Item 1.01. Entry into a Definitive Material Agreement

As previously reported, on August 19, 2014, the Company issued $17.5 million aggregate principal amount of 5.00% Convertible Senior Notes due 2017 (the “Notes”). The Notes are governed by an indenture, dated as of August 19, 2014, between the Company and The Bank of New York Mellon, as trustee.

The interest rate on the Notes is 5.00% per year, payable semiannually in arrears on February 15 and August 15 of each year, beginning on February 15, 2015.

The Notes will mature on August 15, 2017, unless previously converted or repurchased. The Notes are unsecured obligations of the Company, except that the interest payments are secured by funds that have been set aside in an escrow account for that purpose.

Holders may convert the Notes at their option prior to February 15, 2017 when or if certain thresholds have been met or circumstances occur, such as the Company’s stock price exceeds 130% of the conversion price under the Notes for a period of time, or the trading price of the Notes is less than 98% of the conversion price under the Notes for a designated period of time, or certain other specified corporate events occur. In addition, holders may convert their Notes at any time on or after February 15, 2017 and prior to maturity.

The initial conversion price is $7.30 per share (defined in the indenture as a conversion rate of 136.9113 shares of the Company’s common stock per $1,000 principal amount of Notes). The conversion price is subject to customary adjustment events specified in the indenture (including in connection with a “make-whole fundamental change” as defined in the Indenture). In addition, the conversion price is subject to a one-time possible re-set on February 15, 2015, to 110% of the Company’s stock price at that time, if that price per share would be lower than the initial conversion price of $7.30, but in no event may the conversion price be re-set more than 20% downward from the initial conversion price of $7.30. Holders who convert their Notes after February 15, 2015 will, in certain circumstances specified in the indenture, be entitled to receive an interest make-whole payment payable in shares of common stock of the Company.

The Indenture also contains other customary terms for transactions of this type, including a right of note holders, subject to certain conditions, to require the Company to repurchase the Notes in the event of a “fundamental change” (as defined in the indenture) involving the Company.

The indenture also provides for customary events of default which include, without limitation, the following: default in any payment of interest which continues for a period of 30 days; default in the payment of principal of any note when due and payable (whether at stated maturity, upon any required purchase or otherwise); the Company’s failure to comply with its conversion obligations under the notes; certain defaults by the Company or any of its significant subsidiaries with respect to certain indebtedness in excess of $10.0 million; and certain events of bankruptcy, insolvency, or reorganization with respect to the Company or any of its significant subsidiaries; or the pledge and escrow agreement relating to the interest escrow provided for the interest payments for the Notes ceases to be in full force and effect or enforceable prior to its expiration due to a default that fails to be cured within 30 days thereof.

The summary of the foregoing is qualified in its entirety by reference to the text of the Indenture, which is filed as Exhibit 4.1 with this Current Report on Form 8-K and is incorporated herein by reference.

Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

The information set forth under the heading “Indenture” in Item 1.01 of this Current Report on Form 8-K is incorporated herein by reference.

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

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

All Notes presented or surrendered for registration of transfer or for exchange, repurchase or conversion shall (if so required by the Company, the Trustee, the Note Registrar or any co-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 Noteholder thereof or its attorney-in-fact duly authorized in writing.

No service charge shall be charged to the Noteholder for any exchange or registration of transfer of Notes, but the Company or the Trustee may require payment of a sum sufficient to cover any tax, assessments or other governmental charges required by law or that may be imposed in connection therewith as a result of the name of the Noteholder of the new Notes issued upon such exchange or registration of transfer of Notes being different from the name of the Noteholder of the old Notes presented or surrendered for such exchange or registration of transfer.

None of the Company, the Trustee, the Note Registrar or any co-registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion, (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 19 or (iii) any Notes, or a portion of any Note, selected for redemption in accordance with Article 17.

As used in Section 2.06(d) and Section 2.06 (e), the term “transfer” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security.

Until the date (the “Resale Restriction Termination Date”), that is the later of (1) the date that is one year after the last date of original issuance of the Notes, or such shorter period of time as permitted by Rule 144 under the Securities Act or any successor provision thereunder and (2) such later date, if any, as may be required by applicable laws, any certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion thereof which shall bear the legend set forth in Section 2.06(e), if applicable) shall bear a legend in substantially the following form (unless such Notes have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company in writing, with notice thereof to the Trustee):

DUE 2017 (THE ‘‘COMPANY’’), EXCEPT (A) TO THE COMPANY OR ANY AFFILIATE THEREOF, (B) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT, (C) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A UNDER THE SECURITIES ACT (‘‘RULE 144A’’), TO A PERSON IT REASONABLY BELIEVES IS A ‘‘QUALIFIED INSTITUTIONAL BUYER’’ AS DEFINED IN RULE 144A THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A OR (D) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE COMPANY’S AND THE TRUSTEE’S RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSE (D) TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE.

BY ITS ACQUISITION OF THIS SECURITY, THE HOLDER THEREOF WILL BE DEEMED TO HAVE REPRESENTED AND WARRANTED THAT EITHER (1) NO PORTION OF THE ASSETS USED BY SUCH HOLDER TO ACQUIRE OR HOLD THIS SECURITY CONSTITUTES THE ASSETS OF AN EMPLOYEE BENEFIT PLAN THAT IS SUBJECT TO TITLE I OF THE U.S. EMPLOYEE RETIREMENT INCOME SECURITY ACT OF 1974, AS AMENDED (‘‘ERISA’’), OF A PLAN, INDIVIDUAL RETIREMENT ACCOUNT OR OTHER ARRANGEMENT THAT IS SUBJECT TO SECTION 4975 OF THE INTERNAL REVENUE CODE OR PROVISIONS UNDER ANY OTHER FEDERAL, STATE, LOCAL, NON-U.S. OR OTHER LAWS OR REGULATIONS THAT ARE SIMILAR TO SUCH PROVISIONS OF ERISA OR THE INTERNAL REVENUE CODE (‘‘SIMILAR LAWS’’), OR OF AN ENTITY WHOSE UNDERLYING ASSETS ARE CONSIDERED TO INCLUDE ‘‘PLAN ASSETS’’ OF ANY SUCH PLAN, ACCOUNT OR ARRANGEMENT, OR (2) THE ACQUISITION, HOLDING AND, IF APPLICABLE, CONVERSION OF THIS SECURITY WILL NOT CONSTITUTE A NON-EXEMPT PROHIBITED TRANSACTION UNDER SECTION 406 OF ERISA OR SECTION 4975 OF THE INTERNAL REVENUE CODE OR A SIMILAR VIOLATION UNDER ANY APPLICABLE SIMILAR LAWS.

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

Promptly after one-year has elapsed following the last date of (1) original issuance of the Notes or (2) original issuance of any Additional Notes under Section 2.11 of this Indenture, if the Notes (including any Additional Notes with the same terms and the same CUSIP number as the Notes) and Common Stock issued upon conversion of the Notes are freely tradable pursuant to Rule 144 under the Securities Act by holders who are not Affiliates of the Company, the Company shall:

(i) Notify the Trustee to remove the restrictive legends described in this Section 2.06(d) and in Section 2.06(e) from the Notes and Common Stock issued upon conversion of the Notes, respectively, and upon such notice the restrictive legend shall be deemed removed from any Global Securities without further action on the part of holders;

(ii) Notify Noteholders and Common Stock issued upon conversion of the Notes that the restrictive legend has been removed or deemed removed; and

(iii) Notify the Trustee and DTC to change the CUSIP number for the Notes and the Common Stock issued upon conversion of the Notes to the unrestricted CUSIP number.

In no event will the failure of the Company to provide any notice set forth in this paragraph or of the Trustee to remove the restrictive legend constitute a failure by the Company to comply with any of its covenants or agreements set forth in this Indenture for purposes of Section 7.01 of this Indenture or otherwise.

Any Note (or security issued in exchange or substitution therefor) as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of such Note for exchange to the Note Registrar in accordance with the provisions of this Section 2.06, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section 2.06(d). The Company shall notify the Trustee in writing upon the occurrence of the Resale Restriction Termination Date and promptly after a Registration Statement with respect to the Notes or any Common Stock issued upon conversion of the Notes has been declared effective under the Securities Act.

Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Section 2.06(d)), 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 transfers of portions of a Global Note in certificated form made upon request of a member of, or a participant in, the Depositary (for itself or on behalf of a beneficial owner) by written notice given to the Trustee by or on behalf of the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section.

The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as Depositary with respect to the Global Note. Initially, the Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co.

If:

(i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days;

(ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 90 days; or

(iii) an Event of Default in respect of the Notes has occurred and is continuing,

upon the request of the beneficial owner of the Notes, the Company will execute, and the Trustee, upon receipt of an Officers’ Certificate and a Company Order for the authentication and delivery of Notes, will authenticate and deliver Notes in definitive form to each such beneficial owner of the related Notes (or a portion thereof) in an aggregate principal amount equal to the principal amount of such Global Note, in exchange for such Global Note, and upon delivery of the Global Note to the Trustee such Global Note shall be canceled.

Definitive Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.06(d) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such definitive Notes to the Persons in whose names such definitive Notes are so registered.

At such time as all interests in a Global Note have been converted, canceled, repurchased or transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is exchanged for definitive Notes, converted, canceled, repurchased or transferred to a transferee who receives definitive Notes therefor or any definitive Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase.

None of the Company, the Trustee nor any agent of the Company or the Trustee will 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.

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

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION.

THE HOLDER OF THIS SECURITY, BY ACQUISITION HEREOF OR A BENEFICIAL INTEREST HEREIN, (1) REPRESENTS THAT IT IS A QUALIFIED INSTITUTIONAL BUYER AS DEFINED UNDER RULE 144A UNDER THE SECURITIES ACT (“RULE 144A”); (2) AGREES ON ITS OWN BEHALF AND ON BEHALF OF ANY INVESTOR ACCOUNT FOR WHICH IT HAS PURCHASED SECURITIES THAT IT WILL NOT, PRIOR TO THE DATE (THE “RESALE RESTRICTION TERMINATION DATE”), ONE YEAR, OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THEREUNDER, AFTER THE LAST DATE OF ORIGINAL ISSUANCE OF THE 5.00% CONVERTIBLE SENIOR NOTES DUE 2017 OF NORTHWEST BIOTHERAPEUTICS, INC. (THE “COMPANY”), RESELL OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY OR ANY COMMON STOCK THAT MAY BE ISSUABLE UPON CONVERSION OF SUCH SECURITY EXCEPT (A) TO THE COMPANY OR ANY AFFILIATE THEREOF, (B) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER, (C) TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A OR (D) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE COMPANY’S AND THE TRANSFERRED AGENT’S RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSE (2)(D) TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/ OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM; AND (3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THE SECURITY EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN PURSUANT TO CLAUSE 2(B)) A NOTICE OF THIS LEGEND. THIS LEGEND WILL BE REMOVED BY THE COMPANY AFTER THE RESALE RESTRICTION TERMINATION DATE.

Any such Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the restrictive legend required by this Section 2.06(e).

(f) [Reserved].

(g) Notwithstanding any provision of Section 2.06 to the contrary, in the event Rule 144 as promulgated under the Securities Act (or any successor rule) is amended to unconditionally change the one year holding period thereunder (or the corresponding period under any successor rule), from and after receipt by the Trustee of the Officers’ Certificate and Opinion of Counsel provided for in this Section 2.06(g), (i) each reference in Section 2.06 (d) to “one year” and in the restrictive legend set forth in such paragraph to “ONE YEAR” shall be deemed for all purposes hereof to be references to such changed period, (ii) each reference in Section 2.06(e) to “one year” and in the restrictive legend set forth in such paragraph to “ONE YEAR” shall be deemed for all purposes hereof to be references to such changed period and (iii) all corresponding references in the Notes (including the definition of Resale Restriction Termination Date) and the restrictive legends thereon shall be deemed for all purposes hereof to be references to such changed period, provided that such changes shall not become effective if they are otherwise prohibited by, or would otherwise cause a violation of, the then-applicable federal securities laws. The provisions of this Section 2.06(g) will not be effective until such time as the Opinion of Counsel and Officers’ Certificate have been received by the Trustee hereunder. This Section 2.06(g) shall apply to successive amendments to Rule 144 (or any successor rule) changing the holding period thereunder.]

Section 2.07. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. Upon the issuance of any substitute Note, the Company or the Trustee may require the payment by the holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note that has matured or is about to mature or has been tendered for repurchase upon a Fundamental Change or is about to be converted into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent 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 2.07 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 or payment or conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other securities without their surrender.

Section 2.08. Temporary Notes. Pending the preparation of Notes in certificated form, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Notes in certificated form 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 Notes in certificated form. Without unreasonable delay the Company will execute and deliver to the Trustee or such authenticating agent Notes in certificated form (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 5.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Notes in certificated form. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Notes in certificated form authenticated and delivered hereunder.

Section 2.09. Cancellation of Notes Paid, Etc. All Notes surrendered for the purpose of payment, repurchase, conversion, exchange or registration of transfer, shall, if surrendered to the Company or any Paying Agent or any Note Registrar or any Conversion Agent, be surrendered to the Trustee and promptly canceled by it, or, if surrendered to the Trustee, shall be promptly canceled by it in accordance with its customary procedures, and no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of canceled Notes in accordance with its customary procedures and, after such disposition, shall deliver a certificate of such disposition to the Company, at the Company’s written request. If the Company shall acquire any of the Notes, such acquisition shall not operate as satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation.

Section 2.10. 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 Noteholders as a convenience to Noteholders; 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 will promptly notify the Trustee in writing of any change in the “CUSIP” numbers, including, without limitation, at such time as the restricted CUSIP shall be removed from the Notes.

Section 2.11. Additional Notes. The Company may, without the consent of Noteholders, issue additional Notes hereunder in the future on the same terms and conditions of the Notes issued hereunder, including placing a portion of the proceeds of such additional Notes in an escrow account to secure any interest payments on or before February 15, 2018 for such additional Notes in accordance with the terms and conditions of the Pledge and Escrow Agreement, except for any differences in the issue price and interest accrued prior to the issue date or first Interest Payment Date of the additional Notes (and may assign a different CUSIP number to such Notes to the extent required by such differences); provided that such differences do not cause the additional Notes to constitute a different class of securities than the Notes for U.S. federal income tax purposes (such additional Notes, the “Additional Notes”). The Notes initially issued hereunder and any such Additional Notes shall rank equally and ratably with each other and shall be treated as a single series for all purposes under this Indenture. The Company may not issue any Additional Notes if any Event of Default has occurred with respect to the Notes.

Section 2.12. Repurchases. The Company, to the extent permitted by law, may directly or indirectly repurchase or otherwise acquire any Notes in the open market or otherwise, whether by a private or public tender, repurchase or exchange offer at any price or by private agreement, without prior notice to Noteholders. Any notes repurchased by the Company may, at the Company’s option, be surrendered to the Trustee for cancellation, but may not be reissued or resold by the Company. Any Notes surrendered for cancellation may not be reissued or resold and will be promptly cancelled.

The filing of these reports with the SEC through its EDGAR database (or any successor thereto) shall satisfy the Company’s obligation to furnish those reports to the Trustee as of the time such documents are filed via the EDGAR database (or any successor thereto); provided, however, that the Trustee shall have no obligation whatsoever to determine whether or not such filings have been made.

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

In case one or more Events of Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 7.01(j) or Section 7.01(k) with respect to the Company (and not solely with respect to such a Significant Subsidiary or a group of Subsidiaries of the Company that in aggregate would constitute a Significant Subsidiary of the Company)), unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the Noteholders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance with Section 9.04, by notice in writing to the Company (and to the Trustee if given by Noteholders), may declare 100% of the principal of and accrued and unpaid interest on all the Notes to be due and payable on the date of such declaration, and there upon the same shall become and shall automatically be immediately due and payable, anything in this Indenture or in the Notes contained to the contrary notwithstanding. If an Event of Default specified in Section 7.01(j) or Section 7.01(k) with respect to the Company (and not solely with respect to a Significant Subsidiary of the Company, or a group of Subsidiaries of the Company that in aggregate would constitute such a Significant Subsidiary of the Company) occurs and is continuing, the principal of all the Notes and accrued and unpaid interest shall automatically be immediately due and payable. This provision, however, is subject to the conditions that 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 Noteholders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes (other than a Default or an Event of Default resulting from nonpayment of principal or interest that shall have become due otherwise than by acceleration, a failure to repurchase any Notes when required upon a Fundamental Change or a failure to deliver, upon conversion, cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, due upon conversion) and rescind and annul such declaration and its consequences and such Default (other than a Default resulting from nonpayment of principal or interest that shall have become due otherwise than by acceleration, a failure to repurchase any Notes when required upon a Fundamental Change or a failure to deliver, upon conversion, cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, due upon conversion) shall cease to exist, and any Event of Default arising therefrom (other than a Default resulting from nonpayment of principal or interest that shall have become due otherwise than by acceleration, a failure to repurchase any Notes when required upon a Fundamental Change or a failure to deliver, upon conversion, cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, due upon conversion) 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 in this Indenture or in the Notes to the contrary, to the extent the Company elects, the sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations under Section 314(a)(1) of the Trust Indenture Act, if any, or as set forth in Section 5.06(b) shall, for the first 180 days after the occurrence of such an Event of Default consist exclusively of the right to receive supplementary interest (“Supplementary Interest”), on the Notes at a rate equal to (i) 0.25% per annum of the principal amount of the Notes outstanding for each day during the first 90 calendar days after the occurrence of such an Event of Default during which such Event of Default is continuing (or, if earlier, the date on which such Event of Default is cured or waived as provided for in this Indenture) and (ii) 0.50% per annum of the principal amount of the Notes outstanding for each day from, and including, the 91st calendar day until the 180th calendar day during which such Event of Default is continuing (or, if earlier, the date on which such Event of Default is cured or waived as provided for in this Indenture). If the Company so elects, such Supplementary Interest shall be payable in the same manner and on the same dates as regular interest on the Notes. In addition to the accrual of Supplementary Interest, after the 180th day of any violation of any obligations the Company has pursuant to (1) Section 314(a)(1) of the Trust Indenture Act or (2) Section 5.06(b) (if such Event of Default is not cured or waived as provided for in this Indenture), either the Trustee or the Noteholders of not less than 25% in aggregate principal amount of the Notes then outstanding may declare the principal amount of the Notes and any accrued and unpaid interest through the date of such declaration to be immediately due and payable. In the event the Company does not elect to pay the Supplementary Interest following an Event of Default in accordance with this paragraph or the Company elected to pay such Supplementary Interest but does not pay the Supplementary Interest when due, the Notes will be immediately subject to acceleration as provided herein by the Trustee or the Noteholders of not less than 25% in aggregate principal amount of the Notes then outstanding.

In order to elect to pay the Supplementary Interest as the sole remedy during the first 180 days after the occurrence of an Event of Default in accordance with the immediately preceding paragraph, the Company must notify all registered holders of Notes, the Trustee and the Paying Agent of such election in writing prior to the close of business on the fifth Business Day after the date on which such Event of Default would otherwise occur. Upon the Company’s failure to timely give such notice, the Notes will be immediately subject to acceleration as provided herein by the Trustee or the Noteholders of not less than 25% in aggregate principal amount of the Notes then outstanding.

In no event shall Supplementary Interest and Rule 144A Additional Interest, in the aggregate, accrue under the terms of this Indenture at a rate exceeding 0.50% per annum in the aggregate for any violation or Default caused by the Company’s failure to be current in respect of its Exchange Act reporting obligations.

Whenever in this Indenture there is mentioned, in any context, the payment of interest on, or in respect of, any Note, such mention shall be deemed to include mention of the payment of “Supplementary Interest” provided for in this paragraph to the extent that, in such context, Supplementary Interest is, was or would be payable in respect thereof pursuant to the provisions of this paragraph, and express mention of the payment of Supplementary Interest (if applicable) in any provisions hereof shall not be construed as excluding Supplementary Interest in those provisions hereof where such express mention is not made. The provisions of this paragraph will not affect the rights of Noteholders in the event of the occurrence of any other Event of Default.

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 such waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Noteholders, and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Noteholders, and the Trustee shall continue as though no such proceeding had been instituted.

Section 7.02. Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of Section 7.01 shall have occurred, the Company shall, upon demand of the Trustee, pay to it, for the benefit of the Noteholders, the whole amount then due and payable on the Notes for principal and interest, with interest on any overdue principal and interest, at the rate borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 8.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated.

In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 7.02, 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 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 Noteholders 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 the Trustee under Section 8.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Noteholders 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 Noteholders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agent and counsel fees and expenses, and including any other amounts due to the Trustee under Section 8.06, 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 Noteholders 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 Noteholder any plan of reorganization, arrangement, adjustment or composition affecting the Noteholder or the rights of any Noteholder thereof, or to authorize the Trustee to vote in respect of the claim of any Noteholder in any such proceeding.

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

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 Noteholders, and it shall not be necessary to make any Noteholders parties to any such proceedings.

Section 7.03. Application of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 7 with respect to the Notes shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

First, to the payment of all amounts due the Trustee under Section 8.06;

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, including Supplementary Interest, if any, or Rule 144 Additional Interest, if any, in default in the order of the date due of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon the overdue installments of interest at the rate borne by the Notes at such time, such payments to be made ratably to the Persons entitled thereto;

Third, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount including the payment of the Fundamental Change Repurchase Price and the cash component of the Conversion Obligation, if any, then owing and unpaid upon the Notes for principal and interest, with interest on the overdue principal and (to the extent that such interest has been collected by the Trustee) upon overdue installments of interest at the rate borne by the Notes at such time, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal and interest without preference or priority of principal 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; and Fourth, to the payment of the remainder, if any, to the Company.

Section 7.04. Proceedings by Noteholders. No Noteholder 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:

(i) such Noteholder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore provided;

(ii) the Noteholders of at least 25% in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder

(iii) such Noteholder or Noteholders shall have offered to the Trustee such security or indemnity satisfactory to it against any loss, liability or expense to be incurred therein or thereby;

(iv) the Trustee for 60 days after its receipt of such notice, request and offer of security or indemnity, shall have not complied with the request to institute any such action, suit or proceeding; and

(v) no direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the holders of a majority in principal amount of the Notes outstanding within such 60-day period pursuant to Section 7.07;

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 Noteholders 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 Noteholder, 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 Noteholders (except as otherwise provided herein) provided that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Noteholders. For the protection and enforcement of this Section 7.04, each and every Noteholder 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 Noteholder to receive payment of the principal (including the Fundamental Change Repurchase Price) of and accrued and unpaid interest on such Note (or conversion consideration due upon conversion) 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 conversion consideration on or after such respective dates against the Company shall not be impaired or affected without the consent of such Noteholder.

Anything in this Indenture or the Notes to the contrary notwithstanding, the holder of any Note, without the consent of either the Trustee or the holder of any other Note, in its own behalf and for its own benefit, may enforce, and may institute and maintain any proceeding suitable to enforce, its rights of conversion as provided herein.

Section 7.05. Proceedings by Trustee. In case of an Event of Default the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

Section 7.06. Remedies Cumulative and Continuing. Except as provided in the last paragraph of Section 2.07, all powers and remedies given by this Article 7 to the Trustee or to the Noteholders 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 Noteholders, 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 any acquiescence therein; and, subject to the provisions of Section 7.04, every power and remedy given by this Article 7 or by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Noteholders.

Section 7.07. Direction of Proceedings and Waiver of Defaults by Majority of Noteholders. The Noteholders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 9.04 shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or with this Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other Noteholder or that would involve the Trustee in personal liability. The Noteholders of a majority in aggregate principal amount of the Notes at the time outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes) determined in accordance with Section 9.04 may on behalf of the Noteholders of all of the Notes waive any past Default or Event of Default hereunder and its consequences except:

(i) a default in the payment of accrued and unpaid interest on, or the principal (including any Fundamental Change Repurchase Price) of, the Notes when due that has not been cured pursuant to the provisions of Section 7.01;

(ii) a failure by the Company to deliver cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, upon conversion of the Notes; or (iii) a default in respect of a covenant or provision hereof which under Article 11 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 Noteholders 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 7.07, 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 7.08. Notice of Defaults. The Trustee shall, within 90 days after the occurrence and continuance of a Default of which a Responsible Officer has actual knowledge, deliver to all Noteholders as the names and addresses of such holders appear upon the Note Register, notice of all Defaults known to a Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such notice; and provided that, except in the case of a Default in the payment of the principal of, or accrued and unpaid interest on, any of the Notes, including without limiting the generality of the foregoing any Default in the payment of any Fundamental Change Repurchase Price or Redemption Price, then in any such event the Trustee shall be protected in withholding such notice if and so long as it in good faith determines that withholding notice is in the interests of the Noteholders.

Section 7.09. Undertaking to Pay Costs. All parties to this Indenture agree, and each Noteholder 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 7.09 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with Section 9.04, or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of, or accrued and unpaid interest on, any Note (including, but not limited to, the Fundamental Change Repurchase Price and the Redemption Price with respect to the Notes being repurchased as provided in this Indenture) on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article 15.

ARTICLE 8
CONCERNING THE TRUSTEE

Section 8.01. 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 case an Event of Default has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs; 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 Noteholders unless such Noteholders have offered to the Trustee indemnity or security satisfactory to it against the losses, costs, expenses and liabilities 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 negligent action, its own 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, after it has been qualified thereunder, the Trust Indenture Act, 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 and the Trust Indenture Act against the Trustee; and

(ii) in the absence of willful misconduct 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 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 holders of not less than a majority in principal amount of the Notes at the time outstanding determined as provided in Section 9.04 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; 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;

(d) 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-registrar with respect to the Notes;

(e) 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 such Responsible Officer of the Trustee had actual knowledge of such event;

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 agents and any authenticating agent for, and to hold them harmless against, any and all loss, claim, damage, liability or expense, including taxes (other than taxes based upon, measured by, or determined by the income of the Trustee), incurred without 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, and arising out of or in connection with the acceptance or administration of this trust 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 8.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a senior claim 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 7.03, 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 8.06 shall not be subordinate to any other liability or indebtedness of the Company (even though the Notes may be so subordinated). The obligation of the Company under this Section 8.06 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 8.06 shall extend to the officers, directors, agents and employees of the Trustee.

Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of Default specified in Section 7.01(i) or Section 7.01(j) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws.

Section 8.07. Officers’ Certificate as Evidence. Except as otherwise provided in Section 8.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or willful misconduct on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee, and such Officers’ Certificate, in the absence of negligence or willful misconduct on the part of the Trustee, shall be full warrant to the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof.

Section 8.08. Conflicting Interests of Trustee. After qualification of this Indenture under the Trust Indenture Act, if any, if the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either (a) eliminate such interest within 90 days, (b) apply to the SEC for permission to continue as Trustee or (c) resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.

There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 8.10. Resignation or Removal of Trustee. (a) The Trustee may at any time resign by giving written notice of such resignation to the Company and by mailing notice thereof to the Noteholders at their addresses as they shall appear on the Note Register. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment within 60 days after the mailing of such notice of resignation to the Noteholders, the resigning Trustee may, upon ten Business Days’ notice to the Company and the Noteholders, petition at the expense of the Company any court of competent jurisdiction for the appointment of a successor trustee, or any Noteholder who has been a bona fide holder of a Note or Notes for at least one year may, subject to the provisions of Section 7.09, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

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

(i) the Trustee shall fail to comply with Section 8.08 within a reasonable time after written request therefor by the Company or by any Noteholder who has been a bona fide holder of a Note or Notes for at least one year, or the Trustee shall cease to be eligible in accordance with the provisions of Section 8.09 and shall fail to resign after written request therefor by the Company or by any such Noteholder, or

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

then, in any such case, the Company may by a Board Resolution remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 7.09, any Noteholder who has been a bona fide holder of a Note or Notes for at least one year may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

(c) The holders of a majority in aggregate principal amount of the Notes at the time outstanding, as determined in accordance with Section 9.04, may at any time remove the Trustee and nominate a successor trustee that shall be deemed appointed as successor trustee unless within ten days after notice to the Company of such nomination the Company objects thereto, in which case the Trustee so removed, at the expense of the Company, or any Noteholder, upon the terms and conditions and otherwise as in Section 8.10(a) provided, may petition any court of competent jurisdiction for an appointment of a successor trustee.

(d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 8.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 8.11.

Section 8.11. Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 8.10 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 8.06, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by such trustee as such, except for funds held in trust for the benefit of holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 8.06.

No successor trustee shall accept appointment as provided in this Section 8.11 unless at the time of such acceptance such successor trustee shall be qualified under the provisions of Section 8.08 and be eligible under the provisions of Section 8.09.

Upon acceptance of appointment by a successor trustee as provided in this Section 8.11, each of the Company and the successor trustee, at the written direction and at the expense of the Company shall deliver or cause to be delivered notice of the succession of such trustee hereunder to the Noteholders at their addresses as they shall appear on the Note Register. If the Company fails to deliver such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be delivered at the expense of the Company.

Section 8.12. Succession by Merger, Etc. Any corporation or other entity into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee (including the administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that in the case of any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee such corporation or other entity shall be qualified under the provisions of Section 8.08 and eligible under the provisions of Section 8.09.

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

Section 8.13. Limitation on Rights of Trustee as Creditor. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Notes), after qualification under the Trust Indenture Act, the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of the claims against the Company (or any such other obligor).

Section 8.14. Trustee’s Application for Instructions from the Company. Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Noteholders under this Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective.

CONCERNING THE NOTEHOLDERS

Section 9.01. Action by Noteholders. Whenever in this Indenture it is provided that the Noteholders of a specified percentage in 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 Noteholders of such specified percentage have joined therein may be evidenced by:

(a) any instrument or any number of instruments of similar tenor executed by Noteholders in person or by agent or proxy appointed in writing;

(b) the record of the Noteholders voting in favor thereof at any meeting of Noteholders duly called and held in accordance with the provisions of Article 10; or

Whenever the Company or the Trustee solicits the taking of any action by the Noteholders, the Company or the Trustee may fix, but shall not be required to, in advance of such solicitation, a date as the record date for determining Noteholders 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 9.02. Proof of Execution by Noteholders. Subject to the provisions of Section 8.01, Section 8.02 and Section 10.05, proof of the execution of any instrument by a Noteholder 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 Noteholders’ meeting shall be proved in the manner provided in Section 10.06.

Section 9.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any Note Registrar may deem the Person in whose name a Note shall be registered upon the Note Register to be, and may 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 on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall be affected by any notice to the contrary. All such payments so made to any holder for the time being, or upon its order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for monies payable upon any such Note. 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 Note in certificated form in accordance with the provisions of this Indenture.

Section 9.04. Company-Owned Notes Disregarded. In determining whether the Noteholders 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 or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company 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 actually knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section 9.04 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 or a Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 8.01, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination.

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.

(j) make any change to the provisions of Article 16 hereof or provisions of the Pledge and Escrow Agreement related to the Pledged Collateral, in each case if such change would adversely affect the right of the Holders.

Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent of Noteholders as aforesaid and subject to Section 11.05, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture.

It shall not be necessary for the consent of the Noteholders under this Section 11.02 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof. After an amendment under this Indenture becomes effective, the Company shall deliver to the Noteholders a notice briefly describing such amendment. However, the failure to give such notice to all the Noteholders, or any defect in the notice, will not impair or affect the validity of the amendment.

Section 11.03. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of this Article 11, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the Noteholders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

Section 11.04. Notation on Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article 11 may, at the Company’s expense, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may, at the Company’s expense, be prepared and executed by the Company, authenticated by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 20.11) and delivered in exchange for the Notes then outstanding, upon surrender of such Notes then outstanding.

Section 11.05. Evidence of Compliance of Supplemental Indenture to Be Furnished Trustee. In addition to the documents required by Section 20.05, the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant hereto complies with the requirements of this Article 11, is permitted or authorized by the Indenture and that such supplemental indenture is the valid and binding obligation of the Company, enforceable against the Company in accordance with its terms.

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE

Section 12.01. Company May Consolidate, Etc. on Certain Terms.

(a) The Company shall not amalgamate or consolidate with, merge with or into, sell, convey, transfer or lease, or otherwise dispose of its and its Subsidiaries’ properties and assets, taken as a whole, substantially as an entirety to, or enter into a binding share exchange with another Person, unless:

(i) (A) the Company is the surviving entity or (B) if the Company is not the resulting, surviving or transferee Person (the “Successor Company”), the resulting, surviving or transferee Person shall be (I) a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia or (II) a corporation or entity treated as a corporation for U.S. Federal income tax purposes organized and existing under the laws of any other jurisdiction, and in the case of either (b)(i) or (ii) the Successor Company (if not the Company) shall expressly assume, by supplemental indenture, executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of the Company under the Notes and this Indenture;

(ii) immediately after giving effect to such transaction, no Event of Default, and no event which, after notice or lapse of time, or both, would become an Event of Default, shall have occurred and be continuing under this Indenture; and

(iii) the conditions set forth in Section 12.03 have been satisfied.

Subject to the provisions of Section 12.02 with respect to a lease, upon any such amalgamation, consolidation, merger, sale, conveyance, transfer, lease or other disposition the Successor Company (if not the Company) shall succeed to, and may exercise every right and power of, the Company under this Indenture.

For purposes of this Section 12.01, the sale, conveyance, transfer, lease or other disposition of the properties and assets of one or more Subsidiaries of the Company substantially as an entirety to another Person, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute the properties and assets of the Company substantially as an entirety on a consolidated basis, shall be deemed to be the sale, conveyance, transfer, lease or other disposition of the properties and assets of the Company substantially as an entirety to another Person.

Section 12.02. Successor Corporation to Be Substituted. In case of any such amalgamation, consolidation, merger, sale, conveyance, transfer or lease or other disposition and upon the assumption by the Successor Company (if not the Company), by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of, accrued and unpaid interest on, all of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company, such Successor Company shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the officers of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance or transfer or other disposition (but not in the case of a lease), the Person named as the “Company” in the first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article 12 may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture.

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

Section 12.03. Opinion of Counsel to Be Given Trustee. No merger, sale, consolidation, sale, conveyance, transfer or lease or other disposition shall be effective unless the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease or other disposition and any such assumption and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article 12.

ARTICLE 13
IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS

Section 13.01. Indenture and Notes Solely Corporate Obligations. No recourse for the payment of the principal of or accrued and unpaid interest on any Note, nor for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company in this Indenture or in any supplemental indenture or in any Note, nor because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, officer or director or Subsidiary, as such, past, present or future, of the Company or of any Successor Company, either directly or through the Company or any Successor Company, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issue of the Notes.

ARTICLE 15
CONVERSION OF NOTES

Section 15.01. Conversion Privilege. (a) Upon compliance with the provisions of this Article 15, a Noteholder shall have the right, at such Noteholder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Note (i) subject to satisfaction of the conditions described in Section 15.01(b) below, at any time prior to February 15, 2017 under the circumstances and during the periods set forth in Section 15.01(b) below, and (ii) at any time on or after February 15, 2017 and prior to 5:00 p.m., New York City time, on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 136.9113 shares of Common Stock (the “Conversion Rate”), subject to adjustment as provided in Sections 15.03 and 15.04 of this Indenture, per $1,000 principal amount of Notes (subject to the settlement provisions of Section 15.02 (the “Conversion Obligation”).

(b) (i) The Notes may be surrendered for conversion during the five consecutive Business Day period immediately after any five consecutive Trading Day period (the “Measurement Period”), in which the Trading Price per $1,000 principal amount of Notes for each Trading Day of such Measurement Period was less than 98% of the product of the then-applicable Conversion Rate on such Trading Day and the Last Reported Sale Price of the Common Stock on such Trading Day. The Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this clause and the definition of Trading Price set forth in this Indenture. The Company shall provide written notice to the Bid Solicitation Agent of the three independent U.S. nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for each. The Bid Solicitation Agent shall have no obligation to determine the Trading Price of the Notes unless requested by the Company, and the Company shall have no obligation to make such request unless a Noteholder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of the Notes would be less than 98% of the product of the then-applicable Conversion Rate and the Last Reported Sale Price of the Common Stock at such time, at which time the Company shall instruct the Bid Solicitation Agent to determine the Trading Price of the Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the then-applicable Conversion Rate and the Last Reported Sale Price of the Common Stock on such Trading Day. If the Company does not, when obligated, instruct the Bid Solicitation Agent to determine the Trading Price of the Notes as provided in the preceding sentence, or if the Company gives such instruction to the Bid Solicitation Agent and the Bid Solicitation Agent fails to make such determination, then the Trading Price per $1,000 principal amount of Notes will be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the then-applicable Conversion Rate on such Trading Day. If the Trading Price condition set forth above has been met on any Trading Day, the Company will so notify the Noteholders, the Trustee and the Conversion Agent (if other than the Trustee) in writing on such Trading Day. If, at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the then-applicable Conversion Rate and the Last Reported Sale Price of the Common Stock on such Trading Day, the Company shall promptly so notify the Trustee, the Conversion Agent (if other than the Trustee) and the Noteholders in writing.

(ii) In the event that the Company elects to:

(A) distribute to all or substantially all holders of its Common Stock rights, options or warrants (other than in connection with a stockholder rights plan) entitling them, for a period of not more than 45 days from the date for such issuance or distribution, to subscribe for or purchase its Common Stock at a price per share that is less than the average of the Last Reported Sale Price of the Common Stock on the ten consecutive Trading Days ending on, and including, the Trading Day immediately preceding the declaration date for such distribution; or

(B) distribute to all or substantially all holders of its Common Stock cash, other assets, debt securities, or rights to purchase securities of the Company, which issuance or distribution has a per share value (as reasonably determined by the Board of Directors or a duly authorized committee thereof) exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the date of declaration for such distribution,

then, in each case, the Company shall notify all Noteholders, the Trustee and the Conversion Agent in writing at least 20 days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, the Notes may be surrendered for conversion at any time until the earlier of (1) 5:00 p.m., New York City time, on the Business Day immediately prior to such Ex-Dividend Date and (2) the Company’s declaration that such issuance or distribution will not take place. No Noteholder may exercise this right to convert if, as a result of holding the Notes, such Noteholder will otherwise participate in the distribution, without having to convert its Notes, at the same time and on the same terms as holders of the Common Stock as if such Noteholder held a number of shares of the Common Stock equal to the applicable Conversion Rate for each $1,000 principal amount of notes held by such Noteholder (calculated on an aggregate basis per Noteholder).

(iii) If:

(A) a Fundamental Change or Make-Whole Fundamental Change occurs prior to the close of business on the Business Day immediately preceding February 15, 2017; or

(B) the Company is a party to a consolidation, merger, binding share exchange or similar transaction, or a transfer or lease of all or substantially all of the assets of the Company and its Subsidiaries taken as a whole, in each case pursuant to which the Common Stock would be converted into cash, securities or other assets;

a Noteholder may convert all or a portion of its notes at any time from and after the 20th Scheduled Trading Day prior to the anticipated effective date of such transaction or event (or, if later, the Business Day after the Company gives notice of such transaction or event), and may convert at the increased Conversion Rate (if any) in connection with such Make-Whole Fundamental Change, from, and including, the Effective Date of such Make-Whole Fundamental Change) until 5:00 p.m., New York City time, on the Business Day that is on the 30^th Scheduled Trading Day immediately following the actual effective date of such transaction or event (or if such transaction or event also constitutes a Fundamental Change, until 5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental Change Repurchase Date corresponding to such Fundamental Change if later than the Business Day that is the 30th Scheduled Trading Day after the actual effective date of such transaction or event). The Company shall notify the Noteholders, the Trustee and the Conversion Agent in writing as promptly as practicable following the date the Company publicly announces the transaction, provided that

(x) the Company shall use commercially reasonable efforts to determine the anticipated effective date of such transaction and make such announcement in time to give such notice not less than 20 Scheduled Trading Days prior to such anticipated effective date and that the Company is not required to give such notice more than 20 Scheduled Trading Days prior to such anticipated effective date; and

(y) if the Company does not have knowledge of such transaction or event at least 20 Scheduled Trading Days prior to the anticipated effective date of such transaction, the Company will provide such notice within two Business Days of the date upon which the Company receives notice, or otherwise becomes aware, of such transaction or event, but in no event later than the actual effective date of such transaction or event.

(iv) The Notes may be surrendered for conversion in any Calendar Quarter after the Calendar Quarter ending December 31, 2014 and only during any such Calendar Quarter, if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) in a period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding Calendar Quarter is equal to 130% of the then-applicable Conversion Price on each applicable Trading Day (such price, the “Conversion Trigger Price”).

(v) If the Company calls the Notes for redemption prior to the close of business on the Business Day immediately preceding February 15, 2017 pursuant to Article 17 hereof, Noteholders may convert their notes at any time prior to the close of business on the second Scheduled Trading Day prior to the Redemption Date, even if the Notes are not otherwise convertible at such time, after which time the Noteholder’s right to convert the Notes will expire (unless the Company defaults in the payment of the Redemption Price, in which case a Noteholder may convert such Notes until the Redemption Price has been paid or duly provided for).

(i) On or after February 15, 2015, if, for at least 20 Trading Days (whether or not consecutive) during the 30 consecutive Trading Day period ending within five Trading Days prior to a Conversion Date the Last Reported Sale Price of the Common Stock exceeds the applicable Conversion Price on each such Trading Day, the Company will, in addition to the other consideration payable or deliverable in connection with such conversion, make an interest make-whole payment (an “Interest Make-Whole Payment”) to such converting Noteholder equal to the sum of the present values of the scheduled payments of interest that would have been made on the Notes to be converted had such Notes remained outstanding from the Conversion Date through the earlier of (i) the date that is three years after the Conversion Date and (ii) the Maturity Date if the Notes had not been so converted. The present values of the remaining interest payments will be computed using a discount rate equal to 2%. Such present value shall be computed by an internationally recognized independent investment banking firm, which may be one of the initial purchasers described in the Offering Memorandum, retained by the Company for this purpose.

(ii) If a Conversion Date occurs after the close of business, on an Interest Record Date but prior to 9:00 a.m., New York City time, on the corresponding Interest Payment Date, the Company will not pay accrued interest to any converting Noteholder and will instead pay the full amount of the relevant interest payment on such Interest Payment Date to the Noteholder of record on such Interest Record Date. In such case, the Interest Make-Whole Payment to such converting Noteholders will equal the present value of all remaining interest payments, starting with the next Interest Payment Date for which interest has not been provided for until the earlier of (i) the date that is three years after the Conversion Date and (ii) the Maturity Date if the Notes had not been so converted, computed using a discount rate equal to 2%. Such present value shall be computed by an internationally recognized independent investment banking firm, which may be one of the initial purchasers described in the Offering Memorandum, retained by the Company for this purpose.

(iii) The Company will satisfy its obligation to pay any Interest Make-Whole Payment in shares of the Common Stock, without a cash payment in lieu of any fractional shares and without further obligation to deliver any shares of the Common Stock or pay any cash in excess of the threshold described in clause (iv) below. However, if the Company receives Stockholder Approval, it may pay any Interest Make-Whole Payment either in cash or in shares of the Common Stock, at its election.

(iv) Notwithstanding the foregoing, until the Company receives Stockholder Approval, the number of shares the Company may deliver in connection with a conversion of Notes, including those delivered in connection with an Interest Make-Whole Payment, will not exceed 150.6024 shares per $1,000 principal amount of Notes, subject to adjustment at the same time and in the same manner as the Conversion Rate as set forth in Section 15.04.

(v) If the Company pays an Interest Make-Whole Payment in shares of Common Stock, then the number of shares of Common Stock a Noteholder will receive will be that number of shares that equal to the amount of the Interest Make-Whole Payment to be paid to such Noteholder in shares, divided by the the current Conversion Price.

(d) Notwithstanding the foregoing, if in connection with any conversion the Conversion Rate is adjusted pursuant to Section 15.03, then such Noteholder will not receive the Interest Make-Whole Payment with respect to such Note.

Section 15.02. Conversion Procedure.

(a) [Reserved].

(b) Subject to this Section 15.02, upon any conversion of any Note, the Company shall deliver to converting Noteholders, in respect of each $1,000 principal amount of Notes being converted, solely cash, solely shares of Common Stock or a combination of cash and Common Stock and the Interest Make-Whole Payment, if applicable (each a “Settlement Amount”), at its election, as set forth in this Section 15.02.

(i) All conversions on and after (x) February 15, 2017 or (y) after the issuance by the Company of a Redemption Notice and prior to the close of business on the second Scheduled Trading Day immediately preceding the related Redemption Date will be settled using the same Settlement Method (including the same relative proportion of cash and/or shares of Common Stock as all other conversions occurring on or after February 15, 2017 or after the issuance of the Notice of Redemption, as the case may be.

(ii) Prior to February 15, 2017, the Company will elect (or be deemed to have elected) the same Settlement Method for all conversions occurring on any given Conversion Date. Except for any conversions that occur on or after February 15, 2017 and any conversions that occur after the issuance by the Company of a Redemption Notice but prior to the close of business on the second Scheduled Trading Day preceding the related redemption date, the Company need not elect the same Settlement Method with respect to conversions that occur on different Conversion Dates.

(iii) If, in respect of any Conversion Date (or the period beginning on, but including, February 15, 2017 and ending on, and including, the second Scheduled Trading Day immediately preceding the Maturity Date, as the case may be), the Company elects to deliver a notice (the “Settlement Notice”), of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company, or, at the written request and direction of the Company, the Trustee, shall deliver such Settlement Notice to converting Noteholders no later than the close of business on the second Trading Day immediately following the relevant Conversion Date (or in the case of any conversions occurring on or after February 15, 2017, no later than February 15, 2017). Such Settlement Notice shall specify whether the Company shall satisfy its Conversion Obligation by (A) delivering solely shares of Common Stock, (B) paying solely cash or (C) paying and delivering, as the case may be, a combination of cash and shares of Common Stock and in each case the Interest Make-Whole Payment, if applicable. In the case of an election to pay and deliver, as the case may be, a combination of cash and shares of Common Stock, the relevant Settlement Notice shall indicate the Specified Dollar Amount. If, with respect to any Conversion Date, the Company delivers a Settlement Notice electing to pay and deliver, as the case may be, a combination of cash and shares of Common Stock in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount in such Settlement Notice, the Specified Dollar Amount shall be deemed to be equal to $1,000.

If the Company does not timely deliver a Settlement Notice, the Company will be deemed to have elected to deliver a combination of cash and shares of Common Stock in respect of its Conversion Obligation, and the Specified Dollar Amount shall be deemed to be equal to $1,000.

(iv) The Settlement Amount in respect of any conversion of Notes shall be computed as follows:

(A) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by delivering solely Common Stock, the Company will deliver to the converting Noteholder a number of shares of Common Stock equal to (1) the aggregate principal amount of Notes to be converted, divided by $1,000, multiplied by (2) the then-applicable Conversion Rate and the Interest Make-Whole Payment, if applicable;

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by paying solely cash, the Company shall pay to the converting Noteholder cash in an amount per $1,000 principal amount of Notes being converted equal to the sum of the Daily Conversion Values for each of the 40 consecutive VWAP Trading Days during the related Cash Settlement Averaging Period and the Interest Make-Whole Payment, if applicable; and

(C) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by paying and delivering, as the case may be, a combination of cash and shares of Common Stock, if any, the Company shall pay and deliver, as the case may be, in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 40 consecutive VWAP Trading Days during the related Cash Settlement Averaging Period and the Interest Make-Whole Payment, if applicable.

(v) The Company will also deliver to each converting Noteholder cash in lieu of fractional shares of Common Stock as set forth pursuant to Section 15.02(l).

(vi) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Cash Settlement Averaging Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash deliverable in lieu of fractional shares (if any), the Company shall notify the Trustee and the Conversion Agent of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash deliverable in lieu of fractional shares of Common Stock. The Trustee and the Conversion Agents shall have no responsibility for any such determination.

(d) Before any holder of a beneficial interest in a Global Note shall be entitled to convert the same as set forth above, such holder shall comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such holder is not entitled as set forth in Section 15.02(j) and, if required, all transfer or similar taxes and duties, if any, as set forth in Section 15.02(g).

Before a Noteholder of a Note issued in certificated form shall be entitled to convert the same as set forth above, such Noteholder shall:

(1) complete and manually sign and deliver an irrevocable notice to the Conversion Agent in the form on the reverse of such certificated Note (or a facsimile thereof) (Exhibit B hereto) (a “Notice of Conversion”), at the office of the Conversion Agent and shall state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Noteholder wishes the certificate or certificates for any shares of Common Stock, if any, to be delivered upon settlement of the Conversion Obligation to be registered;

(2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent;

(3) if required, furnish appropriate endorsements and transfer documents;

(4) if required, pay all documentary, stamp, transfer or similar taxes, if any as set forth in Section 15.02(g); and

(5) if required, pay funds equal to interest payable on the next Interest Payment Date to which such holder is not entitled as set forth in Section 15.02(j).

The Trustee (and if different, the relevant Conversion Agent) shall notify the Company of any conversion pursuant to this Article 15 on the date of such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a holder thereof if such holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 19.03.

If more than one Note shall be surrendered for conversion at one time by the same holder, the Conversion Obligation with respect to such Notes, if any, that shall be payable upon conversion shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered.

(e) Each conversion shall be deemed to have been effected immediately prior to 5:00 p.m., New York City time, on the date (the “Conversion Date”), that the Noteholders has complied with all of the requirements set forth in Section 15.02(d).

Except as set forth under Section 15.03 and Section 15.06, if the Company elects to satisfy the related Conversion Obligation solely in shares of Common Stock, the Company shall deliver the shares of Common Stock due in respect of the Conversion Obligation on the third Trading Day immediately following the relevant Conversion Date; provided that for all such conversions occurring on or after February 15, 2017, the Company will deliver the Conversion Obligation on the Maturity Date.

Except as set forth under Section 15.03 and Section 15.06, in the case of any other Settlement Method, the Company shall pay and deliver, as the case may be, the cash and/or shares of Common Stock by the close of business on the third Business Day immediately following the last VWAP Trading Day of the Cash Settlement Averaging Period (and delivery on such third Business Day shall be deemed timely and shall not result in any Default under the Notes even if such Business Day occurs after the Maturity Date of the Notes).

If any shares of Common Stock are due to converting Noteholders, the Company shall issue or cause to be issued, and deliver to the stock transfer agent or to such Noteholder, or such Noteholder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the number of full shares of Common Stock to which such Noteholder shall be entitled in satisfaction of such Conversion Obligation.

(f) In case any Note in certificated form shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the holder of the Note so surrendered, without charge to such holder, a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note.

Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation in their books and records as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected through any Conversion Agent other than the Trustee.

(g) If a holder submits a Note for conversion, the Company shall pay all documentary, stamp and other similar issue or transfer tax or other duties, if any, due on the issue of any shares of Common Stock upon conversion, unless such tax is due because the holder requests any shares of Common Stock to be issued in a name other than the holder’s name, in which case the holder will pay that tax. The stock transfer agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the holder’s name until the Trustee receives a sum sufficient to pay any tax that will be due because the shares are to be issued in a name other than the holder’s name. Nothing herein shall preclude any tax withholding required by law or regulations.

(h) Except as provided in Section 15.04, no adjustment shall be made for dividends on any shares issued upon the conversion of any Note as provided in this Article.

(i) [Reserved].

(j) Upon conversion, a Noteholder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth below. The Company’s settlement of its Conversion Obligations as described above shall be deemed to satisfy its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any to, but not including, the Conversion Date. As a result, accrued and unpaid interest, if any to, but not including, the Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of a Note into a combination of cash and shares of Common Stock, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion.

Notwithstanding the final sentence of the preceding paragraph, if Notes are converted after 5:00 p.m., New York City time, on an Interest Record Date but prior to 9:00 a.m., New York City time, on the immediately following Interest Payment Date, Noteholders of such Notes as of 5:00 p.m., New York City time, on the Interest Record Date will receive the interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from 5:00 p.m., New York City time, on any Interest Record Date to 9:00 a.m., New York City time, on the corresponding Interest Payment Date must be accompanied by payment of an amount equal to the interest, if any payable on the Notes so converted (whether or not the Noteholder of such Notes was the holder of record); provided, however, that no such payment shall be required:

(1) if the Company has specified a Fundamental Change Repurchase Date that is after an Interest Record Date but on or prior to the corresponding Interest Payment Date;

(2) to the extent of any overdue interest, if any, existing at the time of conversion with respect to such Note;

(3) if the Notes are surrendered for conversion after 5:00 p.m., New York City time, on the Interest Record Date immediately preceding the Maturity Date; or

(4) if the Company has specified a Redemption Date that is after an Interest Record Date but on or prior to the Business Day immediately following the corresponding Interest Payment Date.

Except as described above, no payment or adjustment will be made for accrued and unpaid interest on converted Notes.

(k) The Person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as a stockholder of record as of 5:00 p.m., New York City time, on the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation solely in shares of Common Stock) or the last Trading Day of the related Cash Settlement Averaging Period (in the case of any other Settlement Method), as the case may be; provided, however, if such Conversion Date or such last Trading Day of the Cash Settlement Averaging Period occurs on any date when the stock transfer books of the Company shall be closed, such occurrence shall not be effective to constitute the Person or Persons entitled to receive any such shares of Common Stock due upon conversion as the record holder or holders of such shares of Common Stock on such date, but such occurrence shall be effective to constitute the Person or Persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at 5:00 p.m., New York City time, on the next succeeding day on which such stock transfer books are open. Upon conversion of Notes, such Person shall no longer be a Noteholder.

(l) For each Note surrendered for conversion, if the Company has elected to deliver a combination of cash and shares of Common Stock in respect of its Conversion Obligation, the number of full shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the applicable Cash Settlement Averaging Period and any fractional shares remaining after such computation shall be paid in cash. The Company shall not issue fractional shares of Common Stock upon conversion of Notes. Instead, the Company shall pay cash in lieu of fractional shares based on the VWAP on the relevant Conversion Date (if the Company elects to satisfy its Conversion Obligation solely in shares of Common Stock) or based on the VWAP on the last VWAP Trading Day of the relevant Cash Settlement Averaging Period (in the case of any other Settlement Method). If more than one Note shall be surrendered for conversion at one time by the same holder, the number of full shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof) so surrendered.

Section 15.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes. (a) Notwithstanding anything herein to the contrary, if the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date, the Conversion Rate applicable to each Note that is surrendered for conversion, in accordance with this Article 15, at any time from, and including, the Effective Date of a Make-Whole Fundamental Change to 5:00 p.m., New York City time, on the Business Day immediately prior to the related Fundamental Change Repurchase Date corresponding to such Make-Whole Fundamental Change (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change), shall be increased by an amount equal to the Conversion Rate that would, but for this Section 15.03, otherwise apply to such Note pursuant to this Article 15, plus an amount equal to the Make-Whole Conversion Rate Adjustment.

Notwithstanding anything to the contrary herein, if the consideration paid for the Common Stock in any Make-Whole Fundamental Change described in clause (b) of the definition thereof is comprised entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation will be calculated based solely on the Stock Price for the transaction and will be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to (x) (i) the applicable Conversion Rate plus (ii) the Make-Whole Conversion Rate Adjustment, multiplied by (y) such Stock Price. In such event, the Conversion Obligation will be determined and paid to holders in cash on the third Business Day following the Conversion Date.

As used herein, “Make-Whole Conversion Rate Adjustment” shall mean, with respect to a Make-Whole Fundamental Change, the amount set forth in the following table that corresponds to the Effective Date of such Make-Whole Fundamental Change and the Stock Price paid or deemed to be paid per share of Common Stock for such Make-Whole Fundamental Change, all as determined by the Company:

Make-Whole Conversion Rate Adjustment
(per $1,000 principal amount of Notes)

Effective	Stock Price
Date	$6.64		$10.00		$12.50		$15.00		$17.50		$20.00		$22.50		$25.00
8/19/2014		13.6913		6.1150		3.8808		2.5720		1.7217		1.1360		0.7196		0.4810
8/15/2015		13.6913		5.1210		3.1864		2.1233		1.4383		0.9615		0.6164		0.3612
8/15/2016		13.6913		3.2960		1.9624		1.3407		0.9417		0.6525		0.4316		0.2592
8/15/2017		13.6913		0.0000		0.0000		0.0000		0.0000		0.0000		0.0000		0.0000

provided, however, that:

(i) if the exact Stock Price of such Make-Whole Fundamental Change is between two Stock Prices listed in the table above under the column titled “Stock Price,” or if the actual Effective Date of such Make-Whole Fundamental Change is between two Effective Dates listed in the table above in the row immediately below the title “Effective Date,” then the Make-Whole Conversion Rate Adjustment for such Make-Whole Fundamental Change shall be determined by the Company by straight-line interpolation between the Make-Whole Conversion Rate Adjustment set forth for such higher and lower Stock Prices, or for such earlier and later Effective Dates based on a 365-day year, as applicable;

(ii) if the exact Stock Price of such Make-Whole Fundamental Change is greater than $25.00 per share (subject to adjustment in the same manner as the Stock Price as provided in Section 15.03(a)(iii)), or if the exact Stock Price of such Make-Whole Fundamental Change is less than $6.64 per share (subject to adjustment in the same manner as the Stock Price as provided in Section 15.03(a)(iii)), then the Make-Whole Conversion Rate Adjustment shall be equal to zero and this Section 15.03 shall not require the Company to increase the Conversion Rate with respect to such Make-Whole Fundamental Change;

(iii) if an event occurs that requires, pursuant to this Article 15 (other than solely pursuant to this Section 15.03), an adjustment to the Conversion Rate, then, on the date and at the time such adjustment is so required to be made, each price set forth in the table above under the column titled “Stock Price” shall be deemed to be adjusted so that such Stock Price, at and after such time, shall be equal to the product of (1) such Stock Price as in effect immediately before such adjustment to such Stock Price and (2) a fraction whose numerator is the Conversion Rate in effect immediately before such adjustment to the Conversion Rate and whose denominator is the Conversion Rate to be in effect, in accordance with this Article 15, immediately after such adjustment to the Conversion Rate;

(iv) [Reserved];

(v) each Make-Whole Conversion Rate Adjustment set forth in the table above shall be adjusted in the same manner in which, and for the same events for which, the Conversion Rate is to be adjusted pursuant to Section 15.04; and

(vi) in no event will the total number of shares of Common Stock issuable upon conversion of the Notes exceed 136.9113 per $1,000 principal amount of Notes, subject to adjustment in the same manner as the applicable Conversion Rate pursuant to Section 15.04.

(b) The Company shall mail to each Noteholder, the Trustee and the Conversion Agent written notice of the Effective Date of any Make-Whole Fundamental Change and will file a Form 8-K, to the extent required by applicable securities laws, announcing such Effective Date. Each such notice shall also state that in connection with such Make-Whole Fundamental Change, the Company shall increase, in accordance herewith, the Conversion Rate applicable to Notes entitled as provided herein to such increase (along with a description of how such increase shall be calculated and the time periods during which Notes must be surrendered in order to be entitled to such increase).

Nothing in this Section 15.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 15.04 in respect of a Make-Whole Fundamental Change.

Section 15.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as follows:

(a) On February 15, 2015 the Conversion Price shall be reset to the lower of (a) the initial Conversion Price or (b) 110% of the common stock price on the 10 trading days ending on February 15, 2015. However, in no event shall the reset Conversion Rate be lower than 80% of the initial Conversion Price, subject to customary adjustments. In connection with any such reset, the Conversion Rate will likewise be adjusted accordingly.

(b) If the Company exclusively issues shares of Common Stock as a dividend or distribution to all or substantially all holders of the outstanding Common Stock on shares of Common Stock, or if the Company effects a share split or share combination, the Conversion Rate will be adjusted based on the following formula:

where

CR₀ =

the Conversion Rate in effect immediately prior to 9:00 a.m., New York City time, on the Ex-Dividend Date for such dividend or distribution, or 9:00 a.m., New York City time, on the effective date of such share split or share combination, as the case may be;

CR¹ =

the Conversion Rate in effect immediately after 9:00 a.m., New York City time, on the Ex-Dividend Date for such dividend or distribution, or 9:00 a.m., New York City time, on the effective date of such share split or share combination, as the case may be;

OS₀ =

the number of shares of Common Stock outstanding immediately prior to 9:00 a.m., New York City time, on the Ex-Dividend Date for such dividend or distribution, or 9:00 a.m., New York City time, on the effective date of such share split or share combination, as the case may be; and

OS¹ =

the number of shares of Common Stock outstanding immediately after, and solely as a result of, such dividend or distribution, or such share split or share combination, as the case may be.

Such adjustment shall become effective immediately after 9:00 a.m., New York City time, on the Ex-Dividend Date for such dividend or distribution or the effective date for such share split or share combination, as the case may be. If any dividend or distribution of the type described in this Section 15.04(b) is declared but not so paid or made, or the outstanding shares of Common Stock are not split or combined, as the case may be, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, or split or combine the outstanding shares of Common Stock, as the case may be, to the Conversion Rate that would then be in effect if such dividend, distribution, share split or share combination had not been declared. For purposes of this Section 15.04(b), “effective date” means the first date on which the shares of Common Stock trade on the Relevant Stock Exchange, regular way, reflecting the relevant share split or share combination, as applicable.

(c) In case the Company shall distribute to all or substantially all holders of its Common Stock any rights, options or warrants entitling them for a period of not more than 45 calendar days after the declaration date of such distribution to subscribe for or purchase shares of the Common Stock, at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the declaration date for such distribution, the Conversion Rate shall be adjusted based on the following formula:

where

CR₀ =

the Conversion Rate in effect immediately prior to 9:00 a.m., New York City time, on the Ex—Dividend Date for such distribution;

CR¹ =

the Conversion Rate in effect immediately after 9:00 a.m., New York City time, on the Ex—Dividend Date for such distribution;

OS₀ =

the number of shares of the Common Stock that are outstanding immediately prior to 9:00 a.m., New York City time, on the Ex-Dividend Date for such distribution;

X =

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

Y =

the number of shares of the Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices of Common Stock over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date relating to such distribution of such rights, options or warrants.

Such adjustment under this Section 15.04(c) shall be successively made whenever any such rights, options or warrants are distributed and shall become effective immediately after 9:00 a.m., New York City time, on the Ex-Dividend Date for such distribution. If any right, option or warrant described in this Section 15.04(c) is not issued or, if so issued, is not exercised prior to the expiration of the exercisability thereof or shares of the Common Stock are not delivered upon exercise of such rights, options or warrants, the new Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such rights, options or warrants had not been so issued or would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of the Common Stock actually delivered.

In determining whether any rights, options or warrants entitle the holders of the Common Stock to subscribe for or purchase shares of the Common Stock at less than the average of the Last Reported Sale Prices of the Common Stock on the ten consecutive Trading Day period ending on and including the Trading Day immediately preceding the declaration date for such distribution, and in determining the aggregate price payable for such shares of the Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

In no event shall the Conversion Rate be decreased pursuant to this Section 15.04(c) (subject to the readjustment provision set forth in this Section 15.04(c)).

(d) In case the Company shall distribute shares of its Capital Stock, evidences of its indebtedness or other of its assets or property, or rights, options, warrants to acquire its Capital Stock or other securities, to all or substantially all holders of its Common Stock, other than:

(i) dividends or distributions covered by Section 15.04(b) and Section 15.04(c);

(ii) dividends or distributions paid exclusively in cash covered by Section 15.04(e); and

(iii) Spin-Offs to which the provisions set forth below in this Section 15.04(d) shall apply

(any of such shares of Capital Stock, evidences of indebtedness, other assets or property, or rights, options or warrants to acquire Capital Stock or other securities, the “Distributed Property”), then, in each such case the Conversion Rate shall be adjusted based on the following formula:

where

CR₀ =

the Conversion Rate in effect immediately prior to 9:00 a.m., New York City time, on the Ex-Dividend Date for such distribution;

CR¹ =

the Conversion Rate in effect immediately after 9:00 a.m., New York City time, on the Ex—Dividend Date for such distribution;

SP₀ =

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

FMV =

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

provided that if “FMV” as set forth above is equal to or greater than “SP0” as set forth above, in lieu of the foregoing adjustment, each Noteholder shall receive, in respect of each $1,000 principal amount of Notes thereof, at the same time and upon the same terms as holders of Common Stock, the amount and kind of Distributed Property such Noteholder would have received had such Noteholder owned a number of shares of Common Stock equal to the Conversion Rate on the record date for such distribution.

If the Board of Directors determines “FMV” for purposes of this Section 15.04(d) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution.

Such adjustment shall become effective immediately after to 9:00 a.m., New York City time, on the Ex-Dividend Date for such distribution.

With respect to an adjustment pursuant to this Section 15.04(d) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company and such Capital Stock or similar equity interest is or when issued will be listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate will be increased based on the following formula:

where

CR₀ =

the Conversion Rate in effect immediately prior to 9:00 a.m., New York City time, on the Ex-Dividend Date for such Spin-Off;

CR¹ =

the Conversion Rate in effect immediately after 9:00 a.m., New York City time, on the Ex-Dividend Date for such Spin-Off;

FMV₀ =

the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock over the first ten consecutive Trading Day period immediately following, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and

MP₀ =

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

The adjustment to the Conversion Rate under the preceding paragraph will be determined on the last Trading Day of the Valuation Period, but will be given effect immediately after the open of business on the Ex-Dividend Date for the Spin-Off. If the Ex-Dividend Date for the Spin-Off is less than ten Trading Days prior to, and including, the end of the observation period in respect of any conversion, references within this clause to ten Trading Days will be deemed to be replaced, solely in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the Spin-Off to, and including, the last Trading Day of such observation period. Notwithstanding the foregoing, in respect of any conversion during the Valuation Period, references within this clause with respect to ten Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date of such Spin-Off to, but excluding, the relevant Conversion Date in determining the Conversion Rate. If any such dividend or distribution described in this Section 15.04(d) is declared but not paid or made, the new Conversion Rate shall be readjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

Subject in all respect to Section 15.10, rights, options or warrants distributed by the Company to all holders of its Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”):

(iv) are deemed to be transferred with such shares of Common Stock;

(v) are not exercisable; and

(vi) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 15.04 (and no adjustment to the Conversion Rate under this Section 15.04 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 15.04(d). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (and a termination or expiration of the existing rights, options or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 15.04 was made:

(1) in the case of any such rights, options or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase; and

(2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued.

For purposes of this Section 15.04(d), Section 15.04(b), and Section 15.04(c), any dividend or distribution to which this Section 15.04(d) is applicable that also includes shares of Common Stock, or rights, options or warrants to subscribe for or purchase shares of Common Stock to which Section 15.04(b) or Section 15.04(c) (or both) applies, shall be deemed instead to be

(1) a dividend or distribution of the evidences of indebtedness, assets or shares of capital stock other than such shares of Common Stock or rights, options or warrants to which Section 15.04(d) applies (and any Conversion Rate adjustment required by this Section 15.04(d) with respect to such dividend or distribution shall then be made) immediately followed by

(2) a dividend or distribution of such shares of Common Stock or such rights, options or warrants (and any further Conversion Rate adjustment required by Section 15.04(b) and Section 15.04(c) with respect to such dividend or distribution shall then be made), except:

(A) the Ex-Dividend Date of such dividend or distribution shall be substituted as “the Ex-Dividend Date,” “the Ex-Dividend Date relating to such distribution of such rights, options or warrants,” the “Record Date for such dividend or distribution” within the meaning of Section 15.04(b) and “the Ex-Dividend Date for such distribution” within the meaning of Section 15.04(c); and

(B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding immediately prior to the Ex-Dividend Date for such dividend or distribution, or the effective date of such share split or share combination, as the case may be” within the meaning of Section 15.04(b) or “outstanding immediately prior to the Ex-Dividend Date for such dividend or distribution” within the meaning of Section 15.04(c).

In no event shall the Conversion Rate be decreased pursuant to this Section 15.04(d) (subject to the readjustment provisions set forth in this Section 15.04(d)).

(e) If the Company shall make any cash dividend or distribution to all or substantially all holders of its Common Stock during any quarterly fiscal period, the Conversion Rate shall be adjusted based on the following formula:

where

CR₀ =

the Conversion Rate in effect immediately prior to 9:00 a.m., New York City time, on the Ex—Dividend Date for such dividend or distribution;

CR¹ =

the Conversion Rate in effect immediately after 9:00 a.m., New York City time, on the Ex—Dividend Date for such dividend or distribution;

SP₀=

the average of the Last Reported Sale Prices of Common Stock over the ten consecutive Trading Day period immediately preceding the Ex-Dividend Date for such dividend or distribution; and

C =

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

Any increase pursuant to this Section 15.04(e) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make or pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Noteholder shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of Common Stock without having to convert its Notes, the amount of cash that such Noteholder would have received if such Noteholder owned a number of shares of Common Stock equal to the Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution.

For the avoidance of doubt, for purposes of this Section 15.04(e), in the event of any reclassification of the Common Stock, as a result of which the Notes become convertible into more than one class of Common Stock, if an adjustment to the Conversion Rate is required pursuant to this Section 15.04(e), references in this Section to one share of Common Stock or Last Reported Sale Price of one share of Common Stock shall be deemed to refer to a unit or to the price of a unit consisting of the number of shares of each class of Common Stock into which the Notes are then convertible equal to the numbers of shares of such class issued in respect of one share of Common Stock in such reclassification. The above provisions of this paragraph shall similarly apply to successive reclassifications.

(f) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer for the Common Stock (including any tender offer that constitutes an exchange offer) and the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders may be made pursuant to such tender offer, the Conversion Rate shall be increased based on the following formula:

where

CR₀ =

the Conversion Rate in effect immediately prior to 9:00 a.m., New York City time, on the Trading Day next succeeding the date such tender offer expires (the “Expiration Date”);

CR¹ =

the Conversion Rate in effect immediately after 9:00 a.m., New York City time, on the Trading Day next succeeding the Expiration Date;

AC =

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

OS₀ =

the number of shares of Common Stock outstanding immediately prior to the Expiration Date (prior to giving effect to such tender offer);

OS¹ =

the number of shares of Common Stock outstanding immediately after the Expiration Date (after giving effect to such tender offer); and

SP¹ =

the average of the Last Reported Sale Prices of Common Stock over the ten consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Expiration Date.

The increase to the Conversion Rate under this Section 15.04(f) shall be determined at the close of business on the tenth Trading Day immediately following, and including, the Trading Day next succeeding the Expiration Date but shall be given effect at the open of business on the Trading Day next succeeding the Expiration Date. Notwithstanding the foregoing, in respect of any conversion within the ten Trading Days immediately following, and including, the Trading Day next succeeding any Expiration Date, references in this Section 15.04(f) with respect to ten Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between such Expiration Date and the Conversion Date in determining the Conversion Rate. Notwithstanding the foregoing, if the Trading Day next succeeding the Expiration Date is less than ten Trading Days prior to, and including, the end of the Observation Period in respect of any conversion of Notes, references in this Section 15.04(f) to ten Trading Days shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, and including, the last Trading Day of such Observation Period.

If the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently prevented by applicable law from effecting any or all or any portion of such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender offer had not been made or had been made only in respect of the purchases that had been effected. In no event shall the Conversion Rate be decreased pursuant to this Section 15.04(f) (except to the extent provided in the preceding sentence).

(g) The term “Record Date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock (or other security) have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise).

(h) [Reserved].

(i) Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices, VWAPs, the Daily Conversion Values or the Daily Settlement Amounts (or any functions of any of these) over a span of multiple days (including a Cash Settlement Averaging Period and, if applicable, the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change), the Board of Directors, or a duly authorized committee thereof, shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, effective date or Expiration Date, as the case may be, of the event occurs, at any time during the period when the Last Reported Sale Prices, the VWAPs, the Daily Conversion Values or the Daily Settlement Amounts (or any functions of any of these) are to be calculated. Notwithstanding this Section 15.04 or any other provision of the Indenture or the Notes, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and a Noteholder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date would be treated as the record holder of the shares of Common Stock as of the related Conversion Date as described under Section 15.02(k) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 15.04, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Noteholder. Instead, such Noteholder shall be treated as if such Noteholder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

(j) In addition to those required by clauses (b), (c), (d), (e) and (f) of this Section 15.04, and to the extent permitted by applicable law and subject to the applicable rules of The Nasdaq Capital Market, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, the Company may also (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection with any dividend or distribution of shares (or rights to acquire shares) or similar event. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to the Noteholder at its last address appearing on the Note Register provided for in Section 2.06 a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

(k) In no event will the Company adjust the Conversion Rate to the extent that the adjustment would reduce the Conversion Price below the par value per share of its Common Stock.

(l) Except as stated herein, the Company shall not adjust the Conversion Rate for the issuance of shares of its Common Stock or any securities convertible into or exchangeable for shares of its Common Stock or the right to purchase shares of its Common Stock or such convertible or exchangeable securities. Without limiting and notwithstanding any of the foregoing, the applicable Conversion Rate will not be adjusted:

(i) on account of stock repurchases that are not tender offers referred to in clause (e) above, including transactions pursuant to any stock repurchase program approved by the Board of Directors;

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

(iii) upon the issuance of any shares of the Common Stock or options or rights to purchase shares of Common Stock pursuant to any present or future employee, director or consultant benefit plan or program or agreement of or assumed by the Company or any of the Company’s Subsidiaries;

(iv) upon the issuance of any shares of the Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in Section 15.04(l)(iii) and outstanding or agreed as of the date the Notes were first issued;

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

(vi) for accrued and unpaid interest, if any; or

(vii) for any transactions described in this Section 15.04 if Noteholders participate (as a result of holding the Notes, and at the same time and on the same terms as holders of Common Stock participate and without having to convert their Notes) in such transactions as if such Noteholders held a number shares of Common Stock equal to the Conversion Rate at the time such adjustment would be required, multiplied by the principal amount (expressed in thousands) of Notes held by such Noteholder.

All calculations and other determinations under this Article 15 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000) of a share. No adjustment in the Conversion Rate shall be required unless such adjustment would require an increase or decrease of at least 1% in such Conversion Rate. However, the Company shall carry forward adjustments that are less than 1% of the Conversion Rate and make such carried forward adjustments (1) when the cumulative net effect of all adjustments not yet made will result in a change of at least 1% of the Conversion Rate or (2) regardless of whether the adjustment (or such cumulative net effect) is less than 1%, (i) on the effective date of any Fundamental Change or Make-Whole Fundamental Change, (ii) (x) on the Conversion Date for any Notes (in the case of Physical Settlement) or in the case of a Cash Settlement following a replacement of Common Stock by Reference Property consisting solely of cash and (y) the first Trading Day of the applicable Observation Period and, in the case of any subsequent adjustments during the applicable Observation Period, on each Trading Day of any Observation Period (in the case of other Cash Settlements or Combination Settlement).

The Trustee and the Conversion Agent shall not at any time be under any duty or responsibility to any holder to determine the conversion rate or whether any facts exist which may require any adjustment of the conversion rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed in making the same. The Trustee and the Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of common stock, or of any securities or property, which may at any time be issued or delivered upon the conversion of any note; and the Trustee and the Conversion Agent make no representations with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for any failure by the Company to issue, transfer or deliver any shares of common stock or stock certificates or other securities or property or cash upon the surrender of any note for the purpose of conversion or to comply with any of our duties, responsibilities or covenants contained in this Indenture.

(m) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly (i) file with the Trustee and any Conversion Agent other than the Trustee an Officers’ Certificate and (ii) file a Form 8-K, to the extent required by applicable securities laws, in each case setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate to the holder of each Note at its last address appearing on the Note Register provided for in Section 2.06 of this Indenture, within ten days of the effective date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(n) For purposes of this Section 15.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company.

(o) If the Company pays withholding taxes on behalf of a Noteholder as a result of an adjustment to the Conversion Rate set forth in this Section 15.04, the Company may, at its option and subject to the other provisions of this Indenture, set off such payments against subsequent payments of cash and Common Stock payable on the Notes or against payments on Common Stock.

Section 15.05. [Reserved].

Section 15.06. Effect of Reclassification, Consolidation, Merger or Sale. Upon the occurrence of:

(i) any recapitalization, reclassification or change of the Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a split, subdivision or combination covered by Section 15.04(b));

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

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

(iv) any statutory share exchange;

in each case pursuant to which Common Stock shall be converted into, or exchanged for, stock, securities or other property or assets (including cash or any combination thereof) (any such event a “Merger Event”), then:

(b) the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) permitted under Section 11.01(b) providing for the conversion and settlement of the Notes as set forth in this Indenture. Such supplemental indenture shall provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 15. If, in the case of any Merger Event, the Reference Property includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, consolidation, merger, combination, sale, conveyance, transfer, lease or other disposition, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Noteholders as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent required by the Board of Directors and practicable the provisions providing for the repurchase rights set forth in Article 19 herein.

In the event the Company shall execute a supplemental indenture pursuant to this Section 15.06, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefore, the kind or amount of stock, securities or other property or assets (including cash or any combination thereof) that will comprise the Reference Property after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Noteholders. The Company shall cause notice of the execution of such supplemental indenture to be delivered electronically or mailed to each Noteholder, at its address appearing on the Note Register provided for in this Indenture, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

(c) Notwithstanding the provisions of Section 15.02(b), and subject to the provisions of Section 15.01 and Section 15.03, at and after the effective time of such Merger Event:

(i) the right to convert each $1,000 principal amount of Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock will be changed to a right to convert such Note into cash, the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such transaction would have owned or been entitled to receive (the “Reference Property”), or a combination of cash and Reference Property; and

(ii) the related Conversion Obligation shall be settled as set forth under Section 15.06(c), it being understood and agreed that for purposes of Section 15.01(b), references therein to “the Last Reported Sale Price of the Common Stock” shall be deemed at and after the effective time of such Merger Event to be references to “the Last Reported Sale Price of a unit of Reference Property comprised of the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of one share of Common Stock immediately prior to such Merger Event would have owned or been entitled to receive (based on the Weighted Average Consideration, if applicable). The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 15.06. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes based on the Common Stock and settled in cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, at the Company’s election, as set forth in Section 15.01 and Section 15.02 prior to the effective date of such Merger Event.

(d) With respect to each $1,000 principal amount of Notes surrendered for conversion after the effective date of any such Merger Event, the Company’s Conversion Obligation shall be settled in cash, units of Reference Property or a combination of cash and units of Reference Property, at the Company’s election, in accordance with Section 15.02(b) as follows:

(i) (A) if the holders of Common Stock receive only cash in as a result of the Merger Event, then for all conversions that occur after the effective date of such Merger Event (A) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any additional shares as described in Section 15.03), multiplied by the price paid per share of Common Stock in such Merger Event and (ii) the Company will satisfy its Conversion Obligation by paying cash to converting Noteholders on the third Business Day immediately following the Conversion Date;

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by delivering solely Reference Property, the Company shall deliver to the converting Noteholder a number of units of Reference Property (each such unit comprised of the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of one share of Common Stock immediately prior to such Merger Event would have owned or been entitled to receive (based on the Weighted Average Consideration, if applicable) equal to (1) the aggregate principal amount of Notes to be converted, divided by $1,000, multiplied by (2) the then-applicable Conversion Rate (as adjusted to reflect the applicable number of units of Reference Property);

(C) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by paying solely cash, the Company shall pay to the converting Noteholder cash in an amount, per $1,000 principal amount of Notes equal to the sum of the Daily Conversion Values for each of the 40 consecutive VWAP Trading Days during the related Cash Settlement Averaging Period, such Daily Conversion Values determined as if the reference to “the VWAP of the Common Stock” in definition thereof were instead a reference to “the VWAP of a unit of Reference Property” comprised of the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of one share of Common Stock immediately prior to such Merger Event would have owned or been entitled to receive (based on the Weighted Average Consideration, if applicable); and

(D) if the Company elects to satisfy its Conversion Obligation through delivery of a combination of cash and Reference Property, the Company shall deliver in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 40 consecutive VWAP Trading Days during the Cash Settlement Averaging Period for such Note, such Daily Settlement Values determined as if the reference to “the VWAP of the Common Stock” in definition of Daily Conversion Value and Daily Share Amount were instead a reference to “the VWAP of a unit of Reference Property comprised of the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of one share of Common Stock immediately prior to such Merger Event would have owned or been entitled to receive (based on the Weighted Average Consideration, if applicable).

(ii) The Company will deliver the cash in lieu of fractional units of Reference Property as set forth pursuant to Section 15.02(l) (provided that the amount of such cash shall be determined as if references in such Section to “the Last Reported Sale Price of the Common Stock” were instead a reference to “the Last Reported Sale Price of a unit of Reference Property” comprised of the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of one share of Common Stock immediately prior to such Merger Event would have owned or been entitled to receive (based on the Weighted Average Consideration, if applicable).

(iii) The Daily Settlement Amounts (if applicable) and Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Cash Settlement Averaging Period.

(iv) For purposes of this Section 15.06, if the Merger Event causes the Common Stock to be converted into the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), the Reference Property into which the notes will be convertible will be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election (the “Weighted Average Consideration”), or, if no holders of our Common Stock affirmatively make such an election, the types and amount of consideration actually received by the holders of Common Stock.

(v) The Company shall notify the Noteholders of the Weighted Average Consideration as soon as practicable after the Weighted Average Consideration is determined.

(vi) If the notes become convertible into Reference Property, the Company will promptly notify the Trustee in writing and file a Form 8-K containing the relevant information, to the extent required by applicable securities laws.

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

Section 15.07. Certain Covenants. (a) The Company shall, prior to the issuance of any Notes hereunder, and from time to time as may be necessary, reserve out of its authorized but unissued Common Stock or shares of Common Stock held in treasury, a sufficient number of shares of Common Stock, free of preemptive rights, to permit the conversion of the Notes.

(b) The Company covenants that all shares of Common Stock issued upon conversion of Notes shall be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof.

(c) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and interpretations of the SEC, secure such registration or approval, as the case may be.

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

Section 15.08. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Noteholder to determine the Conversion Rate (or any adjustment thereto) or Conversion Price or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same.

The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto.

Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article.

Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 15.06 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Noteholders upon the conversion of their Notes after any event referred to in such Section 15.06 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 8.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto.

Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 15.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in Section 15.01(b) with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 15.01(b).

Section 15.09. Notice to Noteholders Prior to Certain Actions.

In case:

(a) the Company shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Conversion Rate pursuant to Section 15.04; or

(b) the Company shall authorize the granting to all of the holders of its Common Stock of rights, options or warrants to subscribe for or purchase any share of any class or any other rights, options or warrants; or

(c) of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Company is a party and for which approval of an stockholders of the Company is required, or of the sale, conveyance, transfer, lease or other disposition of all or substantially all of the assets of the Company; or

(d) of the voluntary or involuntary dissolution, liquidation or winding-up of the Company;

the Company shall cause to be filed with the Trustee and to be mailed to each Noteholder at its address appearing on the Note Register, provided for in Section 2.06 of this Indenture, as promptly as possible but in any event at least 20 days prior to the applicable date hereinafter specified, a notice stating:

(i) the date on which a record is to be taken for the purpose of such dividend, distribution or rights, options or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights are to be determined; or

(ii) the date on which such reclassification, consolidation, merger, sale conveyance, transfer, lease or other disposition, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, conveyance, transfer, lease or other disposition, dissolution or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such divided, distribution, reclassification, consolidation, merger, sale, conveyance, transfer, lease or other disposition, dissolution, liquidation or winding-up.

Section 15.10. Stockholder Rights Plans. To the extent that the Company has a stockholder rights agreement or other “poison pill” in effect upon conversion of the Notes, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights agreement or other poison pill, as the same may be amended from time to time. If at the time of conversion, however, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights agreement or other poison pill so that the Noteholders would not be entitled to receive any rights in respect of Common Stock, if any, issuable upon conversion of the Notes, the Conversion Rate will be adjusted at the time of separation as if the Company has distributed to all or substantially all holders of Common Stock, Distributed Property as provided in Section 15.04(d), subject to readjustment in the event of the expiration, termination or redemption of such rights.

Section 15.11. Exchange in Lieu of Conversion. When a holder surrenders its Notes for conversion, the Company may, at its election (an “Exchange Election”), direct the Conversion Agent to surrender, on or prior to the second Business Day following the relevant Conversion Date, such Notes to a financial institution designated by the Company (the “Designated Institution”), for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion for exchange in lieu of conversion, the Designated Institution must agree to timely deliver, in exchange for such Notes, cash, the shares of Common Stock or a combination of cash and Common Stock that would otherwise be due upon conversion as described in Section 15.02 above and in respect of which the Company has notified to converting Noteholders. If the Company makes the election described above, the Company shall, by 5:00 p.m., New York City time, on the second Business Day following the relevant Conversion Date as part of its Settlement Notice, notify the holder surrendering its Notes for conversion that it has made such Exchange Election. In addition, the Company shall concurrently notify the Designated Institution of the Settlement Method (and, if applicable, the Specified Dollar Amount) that Company has elected with respect to such conversion and the relevant deadline for delivery of the consideration due upon conversion. Any Notes exchanged by the Designated Institution will remain outstanding.

(a) If the Designated Institution agrees to accept any Notes for exchange but does not timely deliver the related consideration due upon conversion to the Conversion Agent, or if the Designated Institution does not accept such Notes for exchange, the Company shall, within the time period specified in Section 15.02(e), convert such Notes into cash and/or shares of Common Stock, as applicable in accordance with the provisions of Section 15.02, as if it had not made such Exchange Election.

(b) For the avoidance of doubt, in no event will the Company’s designation of a Designated Institution pursuant to this Section 15.11 require the Designated Institution to accept any Notes for exchange.

Section 15.12. Limitations Relating to the NASDAQ Shareholder Approval Requirements. Prior to entering into a transaction or series of transactions that would cause the Company to be unable to satisfy its Conversion Obligation in full solely in shares of Common Stock, the Company shall obtain prior stockholder approval in accordance with the Nasdaq listing standards to the extent required thereunder. In addition, in the event the Company elects to satisfy its Conversion Obligation in a combination of cash and shares of Common Stock and the number of shares and conversion price of such shares issuable upon conversion would require prior stockholder approval in accordance with the listing standards of the NASDAQ Stock Market LLC then the Company will either obtain stockholder approval of any issuance of Common Stock upon conversion of the Notes in excess of such limitations or deliver cash in lieu of any shares of Common Stock otherwise deliverable upon conversions in excess of such limitations (such amount of cash to be based on the last Trading Day of the related Cash Settlement Averaging Period).

ARTICLE 16
COLLATERAL SECURITY

Section 16.01. Collateral Security.

(a) On the Issue Date of the initial Notes issued hereunder, the Company shall (i) enter into the Pledge and Escrow Agreement and thereafter comply with the terms and provisions of such agreement and (ii) pledge the Pledged Collateral to the Escrow Agent for the benefit of the Trustee and the ratable benefit of the Noteholders in such amount as will be sufficient upon receipt of scheduled interest and/or principal payments of such Pledged Collateral to provide for payment in full of the first six scheduled interest payments due on the Notes. The Pledged Collateral shall be pledged by the Company to the Escrow Agent for the benefit of the Trustee and the ratable benefit of the Noteholders and shall be held by the Escrow Agent in the Pledge Account pending disposition pursuant to the Pledge and Escrow Agreement. The Pledged Collateral shall also secure the due and punctual payment and performance of all obligations of the Company, whether now or hereafter existing, under the Notes, this Indenture and the Pledge and Escrow Agreement, including interest accrued on the Notes after the commencement of a bankruptcy, reorganization or similar proceeding involving the Company. Notwithstanding the foregoing, the Pledged Collateral shall not secure obligations of the Company to issue and deliver shares of Common Stock (or other Reference Property) upon conversion of the Notes, provided, however that the Pledged Collateral shall secure the obligations of the Company to pay the principal of, and accrued and unpaid interest, if any, on the Notes in the event of an acceleration upon an Event of Default, including a failure by the Company to comply with its obligations to convert the Securities as set forth in Section 7.01.

(b) Each Noteholder, by its acceptance of a Note, consents and agrees to the terms of the Pledge and Escrow Agreement (including the provisions providing for foreclosure and release of the Pledged Collateral) as such agreement may be in effect or may be amended from time to time in accordance with their terms, and authorizes and directs the Escrow Agent and the Trustee to enter into the Pledge and Escrow Agreement and to perform their respective obligations and exercise their respective rights under such agreement in accordance therewith. The Company will do or cause to be done all such acts and things as may be necessary, or as may be required by the provisions of the Pledge and Escrow Agreement, to assure and confirm to the Escrow Agent and the Trustee the security interest in the Pledged Collateral contemplated hereby, by the Pledge and Escrow Agreement or any part of such agreement, as from time to time constituted, so as to render the same available for the security and benefit of this Indenture and of the Notes secured hereby, according to the intent and purposes herein and therein expressed. The Company shall take, or cause to be taken, any and all actions required to create and maintain, as security for the obligations of the Company under this Indenture and the Notes, a valid, enforceable and perfected first priority lien in and on all the Pledged Collateral, in favor of the Escrow Agent for the benefit of the Trustee and the ratable benefit of the Noteholders, superior to and prior to the rights of third Persons and subject to no other liens.

(c) The release of any portion of the Pledged Collateral pursuant to the Pledge and Escrow Agreement will not be deemed to impair the security under this Indenture in contravention of the provisions hereof if and to the extent the Pledged Collateral are released pursuant to this Indenture and the Pledge and Escrow Agreement. To the extent applicable, the Company shall cause Section 314(d) of the Trust Indenture Act relating to the release of property or securities from the lien and security interest of the Pledge and Escrow Agreement and relating to the substitution therefor of any property or securities to be subjected to the lien and security interest of the Pledge and Escrow Agreement to be complied with. Any certificate or opinion required by Section 314(d) of the Trust Indenture Act may be made by an Officer of the Company, except in cases where Section 314(d) of the Trust Indenture Act requires that such certificate or opinion be made by an independent Person, which Person shall be an independent engineer, appraiser or other expert selected by the Company. The Company shall cause Section 314(b) of the Trust Indenture Act, relating to opinions of counsel regarding the lien under the Pledge and Escrow Agreement, to be complied with.

(d) The Escrow Agent and the Trustee may, in their sole discretion and without the consent of the Noteholders, on behalf of the Noteholders, take all reasonable actions in accordance with the Pledge and Escrow Agreement, necessary or appropriate in order to (i) enforce any of the terms of the Pledge and Escrow Agreement and (ii) collect and receive any and all amounts payable in respect of the obligations of the Company under such agreement. The Escrow Agent and the Trustee shall have power (but not the obligation) to institute and to maintain such suits and proceedings as the they may reasonably deem expedient to preserve or protect their interests and the interests of the Noteholders in the Pledged Collateral (including power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any 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 security interest hereunder or be prejudicial to the interests of the Noteholders, the Escrow Agent or of the Trustee).

ARTICLE 17
REDEMPTION

Section 17.01. Right to Redeem; Notices to Trustee.

(a) The Notes are not redeemable by the Company prior to August 15, 2017. On or after August 15, 2017, except for the Notes that the Company is required to repurchase in accordance with Article 15 hereof, the Company may redeem any or all of the Notes in cash at the Redemption Price (as defined below), provided that the Last Reported Sale Price of the Common Stock for 20 or more Trading Days (whether or not consecutive) in a period of 30 consecutive Trading Days ending on the Trading Day immediately prior to the date of the Redemption Notice exceeds 150% of the applicable Conversion Price in effect on such Trading Day; provided that the Company may not redeem the Notes if the Redemption Date would be after the Maturity Date.

(b) The redemption price at which the Notes are redeemable (the “Redemption Price”) shall be equal to the sum of (i) 100% of the principal amount of Notes to be redeemed, payable in cash, plus (ii) accrued and unpaid interest, if any, to, but excluding, the Redemption Date, payable in cash; provided, however, that if the Redemption Date is after a regular Record Date and prior to the Interest Payment Date to which it relates, the Company will not pay accrued and unpaid interest to any Noteholder surrendering its Notes for redemption, and shall instead pay the full amount of the interest due on such Interest Payment Date to the Noteholder of record on the regular Record Date.

(c) The Company may not redeem any Notes if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the relevant Redemption Date (except in the case of an acceleration resulting from a default by the Company in the payment of the Redemption Price with respect to such Securities).

Section 17.02. Selection of Securities to be Redeemed.

If less than all the outstanding Notes are to be redeemed, the Trustee shall select the Notes to be redeemed in principal amounts of $1,000 or multiples of $1,000 (i) in the case of certificated Notes, by lot, on a pro rata basis or by another method the Trustee considers reasonable, fair and appropriate; and (ii) in the case of global notes, in accordance with the Depositary’s procedures and applicable provisions under this Indenture.

Provisions of this Indenture that apply to Notes called for redemption in whole also apply to Notes called for redemption in part. The Trustee shall notify the Company promptly of the Notes or portions of Notes to be redeemed.

If a portion of any Noteholder’s Notes is selected for redemption and such Noteholder has converted a portion of its Notes before termination of the conversion right with respect to the portion of the Notes so selected, the converted portion of such Notes shall be deemed (so far as may be) to be the portion selected for redemption. Notes which have been converted during a selection of Notes to be redeemed may be treated by the Trustee as outstanding for the purpose of such selection.

Section 17.03. Notice of Redemption.

At least 30 calendar days but not more than 90 calendar days before a Redemption Date, the Company shall deliver electronically or mail a notice of redemption by first-class mail, postage prepaid (or, in the case of Notes held in book entry form, by electronic transmission), to the Trustee, the Paying Agent and each Noteholder to be redeemed in whole or in part at its last address as the same appears on the Note Register (a “Redemption Notice”).

The Redemption Notice shall specify the Notes to be redeemed (including the CUSIP numbers, if any) and shall state:

(a) that the Noteholders have a right to convert the Notes called for redemption upon satisfaction of the requirements therefor set forth in this Indenture;

(b) the Redemption Date;

(d) the applicable Conversion Rate and any adjustments thereto; the relevant Settlement Method for Notes converted pursuant to Section 15.01(b)(5) and, if applicable, the Specified Dollar Amount;

(e) the name and address of the Paying Agent and Conversion Agent;

(f) that Notes called for redemption may be converted at any time before the close of business on the second Scheduled Trading Day immediately preceding the Redemption Date; and

(g) the procedures a Noteholder must follow to exercise rights under Section 17.01.

At the Company’s written request (which request must include the information listed in clauses (a) through (g) above and be received by the Trustee not fewer than 75 calendar days prior (or such shorter period of time as may be acceptable to the Trustee) to the Redemption Date) the Trustee, in the name of and at the expense of the Company, shall mail or cause to be mailed (or in the case of Notes held in book entry form, by electronic transmission) the Redemption Notice not fewer than 30 calendar days nor more than 90 calendar days prior to the Redemption Date to each Noteholder to be redeemed as a whole or in part at its last address as the same appears on the Note Register. The notice, if delivered in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the Noteholder receives such notice. In any case, failure to give such notice or any defect in the notice to the Noteholder of a Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Concurrently with the delivery of any such Redemption Notice, the Company shall file a Form 8-K, to the extent required by applicable securities laws, announcing such redemption. The failure to file a Form 8-K, or any defect therein shall not affect the validity of the Redemption Notice or any of the proceedings for the redemption of any Note called for redemption.

Section 17.04. Effect of Notice of Redemption.

Once the Redemption Notice is delivered as set forth in Section 17.03, Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price, except for Notes that are converted in accordance with the terms of this Indenture.

REPURCHASE OF NOTES AT OPTION OF NOTEHOLDERS

Section 19.01. [Reserved].

Section 19.02. Repurchase at Option of Noteholders upon a Fundamental Change. (a) If there shall occur a Fundamental Change at any time prior to the Maturity Date, then each Noteholder shall have the right, at such Noteholder’s option, to require the Company to repurchase for cash all of such Noteholder’s Notes, or any portion thereof that is an integral multiple of $1,000 principal amount, on the date (the “Fundamental Change Repurchase Date”), specified by the Company that is not less than 20 Business Days and not more than 35 Business Days after the date on which the Company provides the Fundamental Change Company Notice (or, if the Company fails to specify a Fundamental Change Repurchase Date, the 35th Business Day following the date of the Fundamental Change Company Notice, without prejudice to any rights or remedies Noteholders may have on account of such failure) at a cash repurchase price (the “Fundamental Change Repurchase Price”) equal to 100% of the principal amount thereof, together with accrued and unpaid interest, thereon to, but excluding, the Fundamental Change Repurchase Date , unless the Fundamental Change Repurchase Date is after an Interest Record Date and on or prior to the related Interest Payment Date, in which case interest accrued to the Interest Payment Date will be paid to Noteholders as of the preceding Interest Record Date and the Fundamental Change Repurchase Price payable to the Noteholder surrendering the Note for repurchase pursuant to this Article 19 shall be equal to the principal amount of Notes subject to repurchase. Repurchases of Notes under this Section 19.02 shall be made, at the option of the Noteholder thereof, upon:

(i) delivery to the Paying Agent by a Noteholder of a duly completed notice (the “Fundamental Change Repurchase Notice”), in the form set forth on the reverse of the Note on or prior to 5:00 p.m., New York City time, of the Business Day immediately preceding the Fundamental Change Repurchase Date (the “Fundamental Change Expiration Time”); and

(ii) delivery or book-entry transfer of the Notes to the Paying Agent at any time after delivery of the Fundamental Change Repurchase Notice (together with all necessary endorsements) at the Corporate Trust Office of the Paying Agent in The Borough of Manhattan, such delivery being a condition to receipt by the holder of the Fundamental Change Repurchase Price therefor; provided that such Fundamental Change Repurchase Price shall be so paid pursuant to this Section 19.02 only if the Note so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Fundamental Change Repurchase Notice.

The Fundamental Change Repurchase Notice shall state:

(A) if certificated, the certificate numbers of Notes to be delivered for repurchase;

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

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

provided, however, that if the Notes are not in certificated form, the Fundamental Change Repurchase Notice must comply with appropriate Depositary procedures.

Any repurchase by the Company contemplated pursuant to the provisions of this Section 19.02 shall be consummated by the payment of the Fundamental Change Repurchase Price on the later of the Fundamental Change Repurchase Date and the time of the book-entry transfer or delivery of the Note as described in Section 19.04(a).

Notwithstanding anything herein to the contrary, any Noteholder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 19.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the Fundamental Change Expiration Time by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 19.03 below.

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

As provided in this Article 19, the Company is required to repurchase the Notes that have been validly tendered and not withdrawn on the Fundamental Change Repurchase Date, subject to extension to comply with applicable law or the rules of the Relevant Stock Exchange.

(b) On or before the twentieth Business Day after the occurrence of the effective date of a Fundamental Change, the Company shall deliver or cause to be delivered to all Noteholders of record and the Trustee and Paying Agent a notice (the “Fundamental Change Company Notice”), of the occurrence of the effective date of the Fundamental Change and of the repurchase right at the option of the Noteholders arising as a result thereof. Each Fundamental Change Company Notice shall specify:

(i) the events causing the Fundamental Change;

(ii) whether the Fundamental Change is a Make-Whole Fundamental Change;

(iii) the effective date of the Fundamental Change or Make-Whole Fundamental Change;

(iv) the last date on which a Noteholder may exercise the repurchase right pursuant to this Article 16;

(v) the Fundamental Change Repurchase Price;

(vi) the Fundamental Change Repurchase Date;

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

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

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

(x) that the Noteholder must exercise the repurchase right on or prior to the Fundamental Change Expiration Time;

(xi) that the Noteholder shall have the right to withdraw any Notes surrendered prior to the Fundamental Change Expiration Time; and

(xii) the procedures that Noteholders must follow to require the Company to repurchase their Notes.

Simultaneously with providing the Fundamental Change Company Notice, the Company shall file a Form 8-K, to the extent required by applicable securities laws, or publish a notice on the Company’s website or through such other public medium as the Company may use at that time, containing the information provided in the Fundamental Change Company Notice.

No failure of the Company to give the foregoing notices and no defect therein shall limit the Noteholders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 19.02.

(c) Notwithstanding the foregoing, no Notes may be purchased by the Company on any date at the option of the Noteholders upon a Fundamental Change if the principal amount of the Notes has been accelerated (other than in connection with a default in the payment of the Fundamental Change Purchase Price), and such acceleration has not been rescinded, on or prior to such date.

(d) In connection with any purchase offer, the Company will:

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

(ii) file a Schedule TO or any successor or similar schedule, if required under the Exchange Act; and

(iii) otherwise comply with all federal and state securities laws in connection with any purchase of, or offer by the Company to purchase, the Notes.

Section 19.03. Withdrawal of Fundamental Change Repurchase Notice. (a) A Fundamental Change Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this Section 19.03 at any time prior to Fundamental Change Expiration Time, specifying:

(i) the certificate number, if any, of the Note in respect of which such notice of withdrawal is being submitted, or the appropriate Depositary information if the Note in respect of which such notice of withdrawal is being submitted is represented by a Global Note;

(ii) the principal amount of the Note with respect to which such notice of withdrawal is being submitted; and

(iii) the principal amount, if any, of such Note that remains subject to the original Fundamental Change Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000;

provided, however, that if the Notes are not in certificated form, the notice must comply with appropriate procedures of the Depositary.

Section 19.04. Deposit of Fundamental Change Repurchase Price. (a) The Company will deposit with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 5.04) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an amount of money sufficient to repurchase on the Fundamental Change Repurchase Date all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn prior to the Fundamental Change Expiration Time) will be made on the later of:

(i) the Fundamental Change Repurchase Date with respect to such Note (provided the Noteholder has satisfied the conditions in Section 19.02); and

(ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Noteholder thereof in the manner required by Section 19.02

by mailing checks for the amount payable to the Noteholders of such Notes entitled thereto as they shall appear in the Note Register, provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price.

(b) If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to make payment on the Fundamental Change Repurchase Date on all the Notes or portions thereof that are to be repurchased as a result of the corresponding Fundamental Change, then:

(i) such Notes will cease to be outstanding and interest will cease to accrue on such Notes; and

(ii) all other rights of the Noteholders of such Notes will terminate (other than (x) the right to receive the Fundamental Change Repurchase Price and (y) if the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the related Interest Payment Date, the right of the Noteholder of record on such Regular Record Date to receive the related interest payment, if applicable);

in each case whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent.

(c) Upon surrender of a Note that is to be repurchased in part pursuant to 16.02, the Company shall execute and the Trustee shall authenticate and deliver to the holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered.

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of and interest, including Supplementary Interest, if any, and Rule 144 Additional Interest, if any, on all Notes may be declared, by either the Trustee or Noteholders of not less than 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture; provided that upon the occurrence of certain Events of Default under the Indenture, the Notes shall automatically become due and payable.

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

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

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and accrued and unpaid interest, Supplementary Interest, if any, and Rule 144 Additional Interest, if any, on this Note at the place, at the respective times, at the rate and in the lawful money herein prescribed.

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

The Notes are not subject to redemption through the operation of any sinking fund or otherwise.

Upon the occurrence of a Fundamental Change, the holder has the right, at such holder’s option, to require the Company to repurchase for cash all of such holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price.

Subject to the provisions of the Indenture, the holder hereof has the right, at its option, during certain periods and upon the occurrence of certain conditions specified in the Indenture, prior to 5:00 p.m., New York City time on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, at a Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.

Exhibit 10.1

PLEDGE AND ESCROW AGREEMENT

THIS PLEDGE AND ESCROW AGREEMENT (this “Agreement”), dated as of August 19, 2014, is by and among Northwest Biotherapeutics, Inc. (the “Company”), as pledgor, The Bank of New York Mellon, as trustee under the Indenture referred to below (the “Trustee”), and The Bank of New York Mellon, in its capacity as securities intermediary and escrow agent (the “Escrow Agent”).

RECITALS

The Company and the Trustee have entered into the Indenture, dated as of August 19, 2014 (the “Indenture”), pursuant to which the Company will issue $17,500,000 in aggregate principal amount of its 5.00% Convertible Senior Notes due 2017 (the “Securities”). “Holder” means the Person in whose name a Security is registered on the books of the Note Registrar.

The Company desires to establish an escrow account with the Escrow Agent into which certain sums, as fully described in Section 2(a) below, will be, simultaneously with the original issuance of the Securities, deposited by or on behalf of the Company to be held and distributed in accordance with the terms and conditions set forth herein, and the Escrow Agent is willing to establish such an account and to accept such funds in accordance with the terms hereinafter set forth.

Capitalized terms used but not defined herein shall have the meanings assigned to such terms in the Indenture.

AGREEMENT

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

SECTION 1. Establishment of Escrow Account. The Escrow Agent shall establish on the date hereof and maintain in the Trustee’s name an escrow account identified as ABA Number: 021000018; Account Number: 860712; Account Name: Northwest Biotherapeutics Escrow (the “Escrow Account”) to which there shall be immediately credited and held amounts received by the Escrow Agent from the Company in accordance with Section 2 hereof. The funds credited to the Escrow Account shall be applied and disbursed only as provided herein. The Escrow Agent shall segregate the funds credited to the Escrow Account from its other funds held as an agent or in trust. The Escrow Account shall be treated as a “securities account” (within the meaning of Section 8-501(a) of the Uniform Commercial Code of the State of New York as in effect from time to time (the “New York UCC”)) for purposes of the New York UCC with respect to securities and a “deposit account” (within the meaning of Section 9-102 of the New York UCC) for purposes of the New York UCC with respect to cash deposited in or credited to the Escrow Account.

SECTION 2. Deposit To The Escrow Account; Investments.

(a) (i) Simultaneously with the original issuance of the Securities, the Company shall deliver or cause to be delivered to the Escrow Agent for deposit $2,625,000 in immediately available funds (the “Initial Escrow Funds”).

(ii) All amounts to be deposited with the Escrow Agent shall be transferred by wire transfer of immediately available funds to the following account:

The Bank of New York Mellon

ABA No. 021000018

Account No. 860712

Acct Name: Northwest Biotherapeutics Escrow

Attn: Corporate Trust Agency/GLA 111-565

(iii) The Escrow Agent may assume without inquiry that all amounts deposited by the Company under this Section 2 have been correctly computed in accordance with the requirements of the Indenture, that no additional amounts are required to be so delivered and that the Escrow Agent is not required under the Indenture to hold in the Escrow Account any additional amounts other than income earned on investments made in accordance with this Section 2. The Escrow Agent shall not be responsible for investing any income earned on investments or any Excess Escrow Funds (as hereinafter defined) unless agreed to in writing by the Company and the Escrow Agent.

(b) (i) Promptly following the deposit of any such funds into the Escrow Account (and in any event on the date hereof), the Company, after consulting with Oppenheimer & Co. Inc., as sole initial purchaser to the Purchase Agreement, dated as of August 13, 2014 (the “Purchase Agreement”), relating to the Securities, shall provide written instructions to the Escrow Agent pursuant to the form of notice attached hereto as Exhibit A (upon which the Escrow Agent may conclusively rely) no later than 10:00 AM New York City Time on the date hereof as to the specific Permitted Securities in which Escrow Funds are to be invested and until such instructions are given by the Company, the Escrow Agent shall not invest such funds. For purposes of this Agreement, “Permitted Securities” shall mean noncallable direct obligations of, or noncallable obligations, the payment of principal of and interest on which are unconditionally guaranteed by, the U.S. or money market securities issued by Permitted Money Market Funds. “Permitted Money Market Funds” means money market funds with assets consisting of cash securities of the U.S. government and permitted government-sponsored enterprises and privately issued money market securities that have been rated by at least one national rating agency and received the highest credit rating (currently A1 in the case of Standard & Poor’s Ratings Service and P1 in the case of Moody’s Investor Service, Inc.) from each such agency that has rated them. All such amounts shall remain so invested until the Scheduled Interest Payment Date (as hereinafter defined) whereupon, at the written direction of the Company, the Escrow Agent shall withdraw such amounts allocated for the applicable Scheduled Interest Payment pursuant to Section 4 hereof. All interest accrued on the Escrow Funds, if any, shall be added to the Escrow Account and be part of the Escrow Account and the Escrow Funds, for all purposes hereunder. On the Business Day before any Escrow Funds and any interest or income thereon, if any, is to be released under this Agreement, the Escrow Agent shall, at the written direction of the Company, cause the Permitted Securities to be converted into cash. All Permitted Securities from time to time credited to the Escrow Account constituting a “security entitlement” as defined in Section 8-102(a)(17) of the New York UCC shall be held in the name of the Trustee (or its nominee) and in no event shall the Company be or be deemed to be the “entitlement holder” (as such term is defined in Section 8-102(a)(7) of the New York UCC) with respect thereto.

(ii) The Escrow Agent shall not be held liable for the selection of “Permitted Securities” or “Permitted Money Market Funds”, for determining whether an investment constitutes “Permitted Securities” or “Permitted Money Market Funds” or by reason of any insufficiency in the Escrow Account resulting from any loss on any investment included therein. In addition, the Escrow Agent shall not have any liability in respect of losses incurred as a result of the liquidation of any investment prior to its stated maturity or the failure by the Company to provide timely written investment direction.

SECTION 3. Security Interest.

(a) Pledge and Assignment. As security for the Secured Obligations (as defined below), the Company hereby irrevocably pledges, assigns and grants to the Trustee, for itself and the equal and ratable benefit of the Holders, a first priority continuing security interest in, and control of, all of the Company’s right, title and interest in and to all of the following whether now owned or existing or hereafter acquired or created (collectively, the “Collateral”):

(i) the Escrow Account, all security entitlements from time to time carried in the Escrow Account, all funds from time to time held in the Escrow Account, including, without limitation, the Escrow Funds and all certificates and instruments, if any, from time to time, representing or evidencing the Escrow Account or the Escrow Funds;

(ii) all investments of funds in the Escrow Account, all of which shall constitute Permitted Securities, and whether held by or registered in the name of the Escrow Agent or any nominee, all certificates and instruments, if any, from time to time representing or evidencing any such Permitted Securities and all security entitlements to such Permitted Securities;

(iii) all promissory notes, certificates of deposit, deposit accounts, checks and other instruments evidencing Permitted Securities from time to time hereafter delivered to or otherwise possessed by the Escrow Agent, for or on behalf of the Company, in substitution for or in addition to any or all of the then existing Collateral;

(iv) all interest, dividends, cash, instruments, securities and other properties from time to time received, receivable or otherwise distributed in respect of or in exchange for any or all of the then existing Collateral; and

(v) all proceeds of the foregoing.

The Trustee hereby appoints the Escrow Agent to act as the Trustee’s agent, on behalf of the Holders, for purposes of perfecting the foregoing pledge, assignment and security interest in the Collateral, and the Escrow Agent hereby accepts such appointment. Subject to Section 9(b), for so long as the foregoing pledge, assignment and security interest remains in effect, the Escrow Agent hereby waives any right of set off or banker’s lien that it, in its individual capacity or in its capacity as an agent for Persons other than the Trustee and the Holders, may have with respect to any or all of the Collateral.

(b) Secured Obligations. So long as this Agreement is in effect, this Agreement secures the due and punctual payment and performance of all obligations of the Company, whether now or hereafter existing, under the Securities, the Indenture and this Agreement, including, without limitation, interest and premium, if any, accrued on the Securities after the commencement of a bankruptcy, reorganization or similar proceeding involving the Company to the extent permitted by applicable law; notwithstanding the foregoing, “Secured Obligations” shall not include the Company’s obligation to issue and deliver shares of Common Stock (or other reference property) upon conversion of the Securities, provided that for the avoidance of doubt, “Secured Obligations” shall include the Company’s obligations to pay the principal of, and accrued and unpaid interest, if any, on, the Securities in the event of any acceleration upon an Event of Default, including a failure to comply with the Company’s obligations to convert the Securities as set forth in Section 7.01 of the Indenture (collectively, the “Secured Obligations”).

(c) Delivery of Collateral. All certificates or instruments, if any, representing or evidencing all or any portion of the Collateral shall be held by the Escrow Agent on behalf of the Trustee pursuant hereto and shall be in suitable form for transfer by delivery, or shall be accompanied by duly executed instruments of transfer or assignments in blank, all in form and substance sufficient to convey a valid security interest in such Collateral to the Trustee for the Trustee and the equal and ratable benefit of the Holders. All securities in uncertificated or book-entry form and all security entitlements, if any, in each case representing or evidencing the Collateral shall be registered in the name of the Trustee (or any of its nominees) as the registered owner thereof, by book-entry or as otherwise appropriate so as to properly identify the interest of the Trustee therein. In addition, the Escrow Agent shall have the right, at any time following the occurrence and during the continuance of an Event of Default, upon the written request of the Company or the Trustee, to transfer to or to register in the name of the Trustee or any of its nominees any or all of the other Collateral. Except as otherwise provided herein, all Collateral shall be deposited and held in the Escrow Account until withdrawn in accordance with this Agreement. The Escrow Agent shall have the right at any time to exchange certificates or instruments representing or evidencing all or any portion of the Collateral for certificates or instruments of smaller or larger denominations in the same aggregate amount.

(d) Maintaining the Escrow Account. So long as this Agreement is in full force and effect, the parties mutually agree:

(i) subject to the other terms and conditions of this Agreement, all Collateral held by the Escrow Agent pursuant to this Agreement shall be held in the Escrow Account, which shall be subject to the exclusive dominion and control of the Trustee for the benefit of the Trustee and the equal and ratable benefit of the Holders;

(ii) the Escrow Account and all Collateral from time to time therein shall remain segregated from all other funds or other property otherwise held by the Trustee or the Escrow Agent, as applicable;

(iii) all amounts (including, without limitation, any Escrow Funds or interest on or other proceeds of the Escrow Funds or any Permitted Securities held in the Escrow Account) shall remain on deposit in the Escrow Account until withdrawn in accordance with this Agreement;

(iv) that either the Trustee for the equal and ratable benefit of the Holders or, to the extent required by applicable law, the Escrow Agent, for the benefit of the Trustee and the equal and ratable benefit of the Holders, shall be the holder or entitlement holder of all Permitted Securities and other uncertificated securities on the books of the applicable Federal Reserve Bank or other applicable securities intermediary; and

(v) notwithstanding anything to the contrary herein, the Escrow Agent shall comply with all written instructions from the Trustee with respect to the Escrow Account and the security entitlements and other Collateral carried therein without further consent from the Company.

(e) Further Assurances. The Company shall, at the Company’s expense, execute and deliver to the Trustee or its designee such other instruments and documents, and take all further action as is necessary to confirm or perfect the security interest of the Trustee granted or purported to be granted hereby or to enable the Trustee to exercise and enforce its rights and remedies hereunder with respect to any Collateral, and the Company shall take all necessary action to preserve and protect the security interest created hereby as a first priority, perfected lien and encumbrance upon the Collateral.

SECTION 4. Distributions from Escrow Account. Assets on deposit in the Escrow Account shall be withdrawn by the Escrow Agent and transferred only in accordance with this Section 4:

(a) Event of Default.

(i) For so long as an Event of Default has occurred and is continuing under the Indenture, no amounts shall be disbursed from the Escrow Account, except as provided in this Section 4.

(ii) If any Event of Default has occurred and is continuing under Section 7.01 of the Indenture:

(1) The Trustee may, without notice to the Company except as required by applicable law and at any time or from time to time, direct the Escrow Agent to redeem or sell all Collateral and transfer all proceeds thereof to the Paying Agent to apply such funds in accordance with Section 7.03 of the Indenture.

(2) If requested by the Holders pursuant to Section 7.07 of the Indenture, the Trustee may also, in addition to the other rights and remedies provided for herein, exercise in respect of the Collateral all the rights and remedies of a secured party upon default under the New York UCC, and may also, without notice except as specified below, redeem or sell the Collateral or any part thereof in one or more parcels at public or private sales, at any of the Trustee’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Trustee may deem commercially reasonable. The Company agrees that, to the extent notice of sale shall be required by law, at least ten (10) days’ notice to the Company of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notice to the Company. The Trustee shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Trustee may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

(3) Any cash held by the Escrow Agent as Collateral and all net cash proceeds received by the Trustee in respect of any sale or liquidation of, collection from, or other realization upon all or any part of the Collateral may, in accordance with the Indenture, be held by the Trustee as collateral for, and then or at any time thereafter be applied (after payment of any costs and expenses incurred in connection with any redemption, sale, liquidation or disposition of or realization upon the Collateral and the payment of any amounts payable to the Trustee or the Escrow Agent) in whole or in part by the Trustee for the equal and ratable benefit of the itself and the Holders against all or any part of the Secured Obligations in such order as described in Section 7.03 of the Indenture.

(iii) In no event shall the Escrow Agent be deemed to have any knowledge of an Event of Default unless and until a responsible officer of the Escrow Agent receives written notice of such Event of Default from the Company or the Trustee.

(b) Scheduled Interest Payments. Pursuant to the Securities, the Company is obligated to make payments of interest on the Securities semiannually on February 15 and August 15 of each year beginning on February 15, 2015 until the Securities mature on August 15, 2017 (each such interest payment, a “Scheduled Interest Payment”, and the date of each such interest payment, a “Scheduled Interest Payment Date”). The Scheduled Interest Payments due on the Securities are to be made, at the election of the Company, from (1) amounts held in the Escrow Account in accordance with the procedures set forth in Section 4(b)(i) below or (2) other sources of funds available to the Company, as anticipated in Section 4(b)(ii) below, or from any combination of (1) and (2) above; provided, however, that nothing herein shall be construed as limiting the Company’s obligation to make all interest payments due on the Securities at the times and in the amounts required by the Securities, which obligation shall be absolute and unconditional.

(i) Payment of Interest. If the Company elects to cause a Scheduled Interest Payment to be made using funds held in the Escrow Account, then, not later than five (5) Business Days prior to the applicable Scheduled Interest Payment Date, the Company shall direct the Escrow Agent in writing pursuant to the form of notice attached hereto as Exhibit B (upon which the Escrow Agent may conclusively rely) to transfer on the applicable Scheduled Interest Payment Date from the Escrow Account to the Paying Agent funds in a specified amount necessary to provide for payment in full (or, if the Company intends to make a portion of such interest payment with funds in the Escrow Account and the remainder of such interest payment with funds other than those in the Escrow Account, such portion) of the next Scheduled Interest Payment on the Securities. The Escrow Agent shall transfer such specified amount at or prior to 5:00 PM, New York City time on the Business Day prior to the applicable Scheduled Interest Payment Date, as set forth in Section 4(d)(ii) hereof, and shall notify the Company in writing that it has made such transfer to the Paying Agent. If the Company does not intend to utilize the funds in the Escrow Account to make any such Scheduled Interest Payment in full, or does not direct the Escrow Agent in writing to make any such Scheduled Interest Payment, then the Company shall make the Scheduled Interest Payment from Company Funds (as defined in Section 4(b)(ii) below).

(ii) Release of Funds to the Company Due to Direct Payment of Interest by the Company. If the Company makes any Scheduled Interest Payment or a portion of any Scheduled Interest Payment from a source of funds other than the Escrow Account (“Company Funds”), the Company may, after payment in full of such Scheduled Interest Payment and upon at least five (5) Business Days’ prior notice, direct the Escrow Agent in writing pursuant to the form of notice attached hereto as Exhibit B (upon which the Escrow Agent may conclusively rely) to release to the Company (or at the written direction of the Company, to release to a designated third party) an amount of funds or Permitted Securities from the Escrow Account, which is less than or equal to the amount of Company Funds so expended in making the Scheduled Interest Payment (which amount shall be calculated by the Company). Upon receipt of such notice, the Escrow Agent shall pay over or transfer to the Company the requested amount.

(c) Excess Escrow Funds. If, (x) in the course of funding the Escrow Account pursuant to Section 2(a) hereof, the Company either elects or is required to deposit in the Escrow Account funds in an amount greater than that which is required to fund the payment of all remaining Scheduled Interest Payments (in order to permit the Escrow Agent to purchase an amount of Permitted Securities equal to or greater than that which is required to fund the payment of the remaining Scheduled Interest Payments or otherwise) or (y) the balance of the Escrow Account exceeds the remaining Scheduled Interest Payments as a result of cumulative interest payments on the Permitted Securities held in the Escrow Account (any such excess amounts under clauses (x) and (y) being hereinafter referred to as “Excess Escrow Funds”), the Company may, (i) in the case of (x), on the date hereof, and (ii) in the case of (y), upon at least five (5) Business Days’ prior written notice, pursuant to the form of notice attached hereto as Exhibit B (upon which the Escrow Agent may conclusively rely), direct the Escrow Agent, to release to the Company (or at the written direction of the Company, to release to a designated third party) an amount of funds from the Escrow Account, the sum of which is less than or equal to the amount of the Excess Escrow Funds (which amount shall be calculated by the Company); provided, however, that with respect to a request to release Excess Escrow Funds arising under clause (x), the Escrow Agent will not require five (5) Business Days’ prior written notice, and such written notice may be provided concurrently with the investment of the Escrow Fund in the Permitted Securities. Upon receipt of such notice, the Escrow Agent shall pay over or transfer to the Company (or its designated third party, as the case may be) the requested amount; provided, however, that the Escrow Agent shall receive such request from the Company no later than 10:00 AM New York City time on the day such funds are to be remitted.

(d) Wire Transfer.

(i) All funds distributed from the Escrow Account to the Company shall be transferred by wire transfer of immediately available funds to the following account:

(e) Written Instructions; Certificates. The Company shall, upon request by the Escrow Agent, execute and deliver to the Escrow Agent such additional written instructions and certificates hereunder as may be reasonably required by the Escrow Agent to give effect to this Section 4.

SECTION 5. Termination of Security Interest. Upon payment in full of the Scheduled Interest Payments or upon payment in full of the Secured Obligations and satisfaction and discharge of the Indenture pursuant to Article 4 of the Indenture, (a) this Agreement and (b) the security interest evidenced by this Agreement in any Collateral remaining in the Escrow Account shall automatically terminate and be of no further force and effect. Furthermore, upon the release of any Collateral from the Escrow Account in accordance with the terms of this Agreement, whether upon release of such Collateral to Holders as payment of interest on the Securities or to the Company pursuant to Sections 4(b)(ii) or 4(c), or upon payment in full of the Secured Obligations and satisfaction and discharge of the Indenture pursuant to Article 4 of the Indenture, then in each case the security interest evidenced by this Agreement in such Collateral so released shall automatically terminate and be of no further force and effect. The Trustee and the Escrow Agent shall, upon request by the Company, execute and deliver to the Company such additional written instructions and certificates (in form and substance reasonably acceptable to the party executing the same) hereunder as may be reasonably required by the Company to give effect to this Section 5.

SECTION 6. Attorneys-in-Fact. The Company hereby irrevocably appoints each of the Trustee and the Escrow Agent as the Company’s attorney-in-fact, coupled with an interest, with full authority in the place and stead of the Company and in the name of the Company or otherwise, from time to time to take any action and to execute any instrument that may be necessary or advisable to accomplish the purposes of this Agreement, including, without limitation, to receive, endorse and collect all instruments made payable to the Company representing any interest payment, dividend or other distribution in respect of the Collateral or any part thereof and to give full discharge for the same, and the expenses of the Trustee and the Escrow Agent incurred in connection therewith shall be payable by the Company; provided that neither the Trustee nor the Escrow Agent is under any obligation or duty to exercise any authority under this Section 6.

SECTION 7. Trustee or Escrow Agent May Perform. Without limiting the authority granted under Section 6 hereof, if the Company fails to perform any agreement contained herein, the Trustee or the Escrow Agent may, but shall not be obligated to, itself perform, or cause performance of, such agreement, and the expenses of the Trustee or the Escrow Agent incurred in connection therewith shall be payable by the Company and shall be secured by the Collateral.

SECTION 8. Representations, Warranties and Agreements.

(a) The Company represents and warrants that:

(i) The execution, delivery and performance by the Company of this Agreement are within its corporate power, have been duly authorized by all necessary corporate action of the Company, and do not contravene, or constitute a default under, any provision of applicable law or regulation or of any judgment, injunction or order or of any agreement or other instrument binding upon the Company other than any contravention or default that would not, individually or in the aggregate, have a Material Adverse Effect (as defined in the Purchase Agreement) or of the certificate of incorporation or by-laws of the Company.

(ii) The Company (a) is duly organized, validly existing and in good standing under the laws of the State of Delaware, (b) has full corporate power and authority to enter into this Agreement and (c) has the power and authority to pledge and grant a security interest in the Collateral as provided by this Agreement.

(iii) This Agreement has been duly executed and delivered by the Company and constitutes a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms except as such enforceability may be limited by bankruptcy, insolvency, reorganization, receivership, moratorium or other similar laws affecting creditors’ rights generally and by general principles of equity.

(iv) Upon the execution and delivery of this Agreement by the parties hereto and the delivery to the Escrow Agent of the Collateral, the pledge of the Collateral pursuant to this Agreement creates a valid and perfected first priority security interest in the Collateral, securing the payment of the Secured Obligations for the benefit of the Trustee, the Escrow Agent and the Holders, enforceable as such against all creditors of the Company and any persons purporting to purchase any of the Collateral from each of them, subject to applicable law.

(v) Other than the filing of a UCC financing statement in respect of the security interest granted hereunder, no consent of any other person and no consent, authorization, approval, or other action by, and no notice to or filing with, any governmental authority or regulatory body is required either (a) for the pledge by the Company of the Collateral pursuant to this Agreement or for the execution, delivery or performance of this Agreement by the Company or (b) for the exercise by the Trustee or the Escrow Agent of the remedies in respect of the Collateral pursuant to this Agreement.

(vi) Other than as set forth in the Time of Sale Information (as defined in the Purchase Agreement), there are no legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or to which any property of the Company or any of its subsidiaries is the subject, which, if determined adversely to the Company or any of its subsidiaries, would individually or in the aggregate have a Material Adverse Effect; and, to the best of the Company’s knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others.

(vii) The pledge of the Collateral pursuant to this Agreement is not prohibited by any applicable law or governmental regulation, release, interpretation or opinion of the Board of Governors of the Federal Reserve System or other regulatory agency (including, without limitation, Regulations T, U and X of the Board of Governors of the Federal Reserve System).

(viii) All information set forth herein relating to the Collateral is accurate and complete in all material respects.

(b) The Company covenants and agrees that:

(i) it will not (and will not purport to) (a) sell, assign (by operation of law or otherwise) or otherwise dispose of, or grant any option or warrant with respect to, any of the Collateral nor (b) create or permit to exist any Lien upon or with respect to any of the Collateral (except for the liens and security interests granted under this Agreement) and at all times will have the right to pledge the Collateral, free and clear of any Lien or adverse claims (except for the liens and security interests granted under this Agreement);

(ii) it will not (a) enter into any agreement or understanding (other than the Indenture) that restricts or inhibits or purports to restrict or inhibit the Trustee’s or the Escrow Agent’s rights or remedies hereunder, including, without limitation, their right to sell or otherwise dispose of the Collateral or (b) fail to pay or discharge any tax, assessment or levy of any nature with respect to the Collateral not later than three Business Days prior to the date of any proposed sale under any judgment, writ or warrant of attachment with respect to the Collateral; and

(iii) it will not change its jurisdiction of incorporation without 5 days’ prior written notice to the Trustee (or such shorter period as the Trustee may agree in its sole discretion).

(c) The Escrow Agent represents and warrants that it is a New York state banking corporation with trust powers that in the ordinary course of its business maintains securities accounts for others and is acting solely in such capacity in respect of the Escrow Account. The Escrow Agent further represents and warrants that it is a “securities intermediary” within the meaning of Section 8-102(a)(14) of the New York UCC.

(d) For purposes of this Section, “Lien” means, with respect to any asset, any mortgage, deed of trust, lien, pledge, hypothecation, encumbrance, charge or security interest in, on or of such asset.

SECTION 9. Fees and Expenses of Escrow Agent.

(a) The Company agrees to pay the Escrow Agent its agreed-upon compensation for its services as Escrow Agent hereunder promptly upon request therefor, and to reimburse the Escrow Agent for all reasonable and documented expenses of or disbursements incurred by the Escrow Agent in the performance of its duties hereunder, including the reasonable fees, expenses and disbursements of legal counsel to the Escrow Agent, all as provided in the Fee Schedule attached as Annex A hereto.

(b) The Escrow Agent shall have a lien upon any Excess Escrow Funds on deposit in the Escrow Account solely for any costs, expenses and fees that may arise hereunder and may retain that portion of the investment income in the Escrow Account equal to such unpaid amounts, until all such costs, expenses and fees have been paid.

SECTION 10. Rights, Duties and Immunities of Escrow Agent. Acceptance by the Escrow Agent of its duties under this Agreement is subject to the following terms and conditions, which all parties to this Agreement hereby agree shall govern and control the rights, duties and immunities of the Escrow Agent:

(a) The duties and obligations of the Escrow Agent shall be determined solely by the express provisions of this Agreement and the Escrow Agent shall not be liable except for the performance of such duties and obligations as are specifically set out in this Agreement. The Escrow Agent shall not be required to inquire as to the performance or observation of any obligation, term or condition under any agreement or arrangement between the Company and the Trustee (including, but not limited to, the occurrence of any Event of Default under the Indenture). The Escrow Agent is not a party to, and is not bound by, any agreement or other document out of which this Agreement may arise. The Escrow Agent shall be under no liability to any party hereto by reason of any failure on the part of any party hereto (other than the Escrow Agent) or any maker, guarantor, endorser or other signatory of any document or any other person to perform such person’s obligations under any such document. The Escrow Agent shall not be bound by any waiver, modification, termination or rescission of this Agreement or any of the terms hereof, unless evidenced by a writing delivered to the Escrow Agent signed by the proper party or parties and, if the duties or rights of the Escrow Agent are affected, unless it shall give its prior written consent thereto. This Agreement shall not be deemed to create a fiduciary relationship between the parties hereto under state or federal law.

(b) The Escrow Agent shall not be responsible in any manner for the validity or sufficiency of this Agreement or of any property delivered hereunder, or for the value or collectibility of any note, check or other instrument, if any, so delivered, or for any representations made or obligations assumed by any party other than the Escrow Agent. Nothing herein contained shall be deemed to obligate the Escrow Agent to deliver any cash, instruments, documents or any other property referred to herein, unless the same shall have first been received by the Escrow Agent pursuant to this Agreement.

(c) The Company shall be liable for and shall reimburse and indemnify the Escrow Agent and hold the Escrow Agent harmless from and against any and all claims, losses, liabilities, costs, damages or expenses (including reasonable attorneys’ fees and expenses) (collectively, “Losses”) arising from or in connection with or related to this Escrow Agreement or being Escrow Agent hereunder (including but not limited to Losses incurred by the Escrow Agent in connection with its successful defense, in whole or in part, of any claim of gross negligence or willful misconduct on its part), provided, however, that nothing contained herein shall require the Escrow Agent to be indemnified for Losses caused by its gross negligence or willful misconduct. The provisions of this clause (c) shall survive the termination of this Agreement and the resignation or removal of the Escrow Agent.

(d) The Escrow Agent shall be fully protected in acting on and conclusively relying upon any written notice, direction, request, waiver, consent, receipt or other paper or document which the Escrow Agent in good faith believes to have been signed and presented by the Company and/or the Trustee.

(e) The Escrow Agent shall not be liable for any error of judgment, or for any act done or step taken or omitted by it in good faith or for any mistake in act or law, or for anything which it may do or refrain from doing in connection herewith, except its own gross negligence or willful misconduct.

(f) The Escrow Agent may seek the advice of legal counsel in the event of any dispute or question as to the construction of any of the provisions of this Agreement or its duties hereunder, and it shall incur no liability and shall be fully protected in respect of any action taken, omitted or suffered by it in good faith in accordance with the advice or opinion of such counsel.

(g) The agreements set forth in this Section 10 shall survive the resignation or removal of the Escrow Agent, the termination of this Agreement and the payment of all amounts hereunder.

(h) In no event shall the Escrow Agent be liable to the Company, the Trustee or any third party for special, punitive, indirect or consequential damages, including but not limited to lost profits, irrespective of whether such party has been advised of the likelihood of such loss or damage and regardless of the form of action arising in connection with this Agreement.

(i) The Escrow Agent shall not be obligated to take any action hereunder which might in the Escrow Agent’s judgment involve any risk of expense, loss or liability, unless it shall have been furnished with indemnity and/or security satisfactory to it.

(j) The Escrow Agent may perform any duties hereunder either directly or by or through agents and attorneys and the Escrow Agent shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder.

(k) If, at any time, (a) there shall exist any dispute with respect to the holding or disposition of all or any portion of the Escrow Funds or any other obligations of the Escrow Agent hereunder or (b) the Escrow Agent is in doubt as to the action to be taken hereunder, the Escrow Agent is authorized to retain the Escrow Funds until (i) such dispute or uncertainty shall be resolved to the satisfaction of the Escrow Agent in its sole discretion or (ii) the Escrow Agent files an interpleader action in any court of competent jurisdiction, and upon the filing thereof, the Escrow Agent shall be relieved of all liability as to the Escrow Funds and shall be entitled to recover attorneys’ fees, expenses and other costs incurred in commencing and maintaining any such interpleader action. The Escrow Agent shall be entitled to act on any agreement, court order or arbitration decision without further question, inquiry or consent. The Escrow Agent shall have no liability to the Company, the Trustee or any other person with respect to any suspension of performance or disbursement into court, specifically including any liability or claimed liability that may arise, or be alleged to have arisen, out of or as a result of any delay in the disbursement of the Escrow Funds or any delay in or with respect to any other action reasonably required or requested of the Escrow Agent.

(l) In no event shall the Escrow Agent be liable for an amount in excess of the value of the Escrow Funds, valued as of the date of deposit.

SECTION 11. Miscellaneous.

(a) Waiver. No waiver of any provision of this Agreement nor consent to any departure by any party therefrom shall in any event be effective unless the same shall be in writing and signed by each of the non-breaching parties and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

(b) Severability. If, for any reason whatsoever, any one or more of the provisions of this Agreement shall be held or deemed to be inoperative, unenforceable or invalid in a particular case or in all cases, such circumstances shall not have the effect of rendering any of the other provisions of this Agreement inoperative, unenforceable or invalid, and the inoperative, unenforceable or invalid provision shall be construed as if it were written so as to effectuate, to the maximum extent possible, the parties’ intent.

(c) Binding Effect. This Agreement shall inure to and be binding upon the parties and their respective successors and permitted assigns; provided, however, that the Company may not assign its rights or obligations hereunder without the express prior written consent of the Escrow Agent and the Trustee.

(d) Choice of Law. The existence, validity, construction, operation and effect of any and all terms and provisions of this Agreement shall be determined in accordance with and governed by the internal laws of the State of New York, including without limitation the New York UCC, without giving effect to the conflicts of law principles of such State. The securities intermediary’s jurisdiction for purposes of Section 8-110 of the New York UCC shall be the State of New York.

(e) Waiver of Jury Trial. Each party hereby waives any right it may have to a trial by jury in respect to any proceeding directly or indirectly arising out of, under or in connection with this agreement or any transaction contemplated hereby. Each party (a) certifies that no agent or attorney of any other party hereto has represented, expressly or otherwise, that such other party would not, in the event of any proceeding, seek to enforce the foregoing waiver and (b) acknowledges that it and the other parties hereto have been induced to enter into this agreement by, among other things, the mutual waivers and certifications in this Section 11(e).

(f) Consent to New York Jurisdiction. Each party irrevocably submits to the jurisdiction of (a) the Supreme Court of the State of New York, New York County, and (b) the United States District Court for the Southern District of New York, for the purposes of any claim, action or proceeding (“Proceedings”) arising out of this Agreement or any transaction contemplated hereby. Each party agrees to commence any such Proceeding either in the United States District Court for the Southern District of New York or, if such Proceeding may not be brought in such court for jurisdictional reasons, in the Supreme Court of the State of New York, New York County. Each party further agrees that service of any process, summons, notice or document by U.S. registered mail to such party’s respective address set forth below shall be effective service of process for any Proceeding in New York with respect to any matters to which it has submitted to jurisdiction in this Section 11(f). Each party irrevocably and unconditionally waives any objection to the laying of venue of any Proceeding arising out of this Agreement or the transactions contemplated hereby in (i) the Supreme Court of the State of New York, New York County or (ii) the United Stated District Court for the Southern District of New York, and hereby further irrevocably and unconditionally waives and agrees not to plea or claim in any such court that any such Proceeding brought in any such court has been brought in an inconvenient forum. Nothwithstanding anything in this Section 11(f) to the contrary, in the event it is finally judicially determined by (x) the Supreme Court of the State of New York or (y) the United States District Court for the Southern District of New York that a Proceeding may not be maintained in either of such jurisdictions, then the parties may bring such Proceeding in an alternate jurisdiction.

(g) Entire Agreement. This Agreement, the Purchase Agreement, the Securities and the Indenture contain the entire agreement among the parties with respect to the subject matter hereof and supersede any and all prior agreements, understandings and commitments with respect thereto; provided, however, that this Agreement is executed and accepted by the Trustee subject to all terms and conditions of its acceptance of the trust under the Indenture, as fully as if said terms and conditions were set forth at length herein.

(h) Amendments. This Agreement may be amended only by a writing signed by duly authorized representatives of all parties. The Trustee and the Escrow Agent may execute an amendment to this Agreement only if the consent of each of the Holders required by Section 11.02 of the Indenture has been obtained or is not required pursuant to the terms thereof.

(i) Notices. All notices, requests, instructions, orders and other communications required or permitted to be given or made under this Agreement to any party hereto shall be delivered in writing by hand delivery or overnight delivery, or shall be delivered by facsimile with machine confirmation of full delivery not more than 24 hours following such facsimile notice. A notice given in accordance with the preceding sentence shall be deemed to have been duly given upon the sending thereof. Notices should be addressed as follows:

To the Company:

Northwest Biotherapeutics, Inc.

4800 Montgomery Lane

Bethesda, Maryland 20814

Attention: Daralyn Grogg

Fax: 240-627-2141

To the Trustee or the Escrow Agent:

The Bank of New York Mellon

101 Barclay Street, Floor 7E

New York, NY 10286

Attn: Corporate Trust Administration

Fax: 212-815-5704

or at such other address or facsimile number as the specified entity most recently may have designated in writing in accordance with this paragraph to the other parties. The Escrow Agent agrees to accept and act upon instructions or directions pursuant to this agreement sent electronically by unsecured e-mail or facsimile transmission or other similar unsecured electronic methods, provided, however, that the Escrow Agent shall have received an incumbency certificate listing persons designated to give such instructions or directions and containing specimen signatures of such designated persons, which such incumbency certificate shall be amended and replaced whenever a person is to be added or deleted from the listing. If the Company provides the Escrow Agent with instructions via electronic transmission (or instructions by a similar electronic method) and the Escrow Agent acts upon such instructions, the Escrow Agent’s understanding of such instructions shall be deemed controlling. The Escrow Agent shall not be liable for any losses, costs or expenses arising directly or indirectly from the Escrow Agent’s reliance upon and compliance with such instructions notwithstanding such instructions conflict or are inconsistent with a subsequent written instruction. The Company agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Escrow Agent, including without limitation the risk of the Escrow Agent acting on unauthorized instructions, and the risk or interception and misuse by third parties.

(j) Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument. Delivery of an executed counterpart of a signature page to this Agreement by facsimile or electronic transmission shall be effective as delivery of a manually executed counterpart of this Agreement.

(k) Interpretation. The headings of the sections contained in this Agreement are solely for convenience of reference and shall not affect the meaning or interpretation of this Agreement.

(l) Tax Matters. The parties acknowledge that, for tax reporting purposes, all interest attributable to the Escrow Funds shall be allocable to the Company. The Parties agree that, for tax reporting purposes, all interest and other income from investment of the Escrow Account shall, as of the end of each calendar year and to the extent required by the Internal Revenue Service, be reported as having been earned by the Company, whether or not such income was disbursed during such calendar year. The Company agrees to provide the Escrow Agent with certified tax identification numbers by furnishing appropriate Form W-9 (or Form W-8, in the case of non-U.S. persons) and other forms and documents that the Escrow Agent may reasonably request. The Company acknowledges that failure to supply such information may obligate the Escrow Agent to withhold a portion of any payments made to the Company pursuant to this Agreement under the applicable provisions of the Internal Revenue Code of 1986, as amended from time to time.

(m) USA Patriot Act Information. To help the government fight the funding of terrorism and money laundering activities, federal law requires all financial institutions to obtain, verify and record information that identifies each person who opens an account. For a non-individual person such as a business entity, a charity, a trust or other legal entity the Escrow Agent will ask for documentation to verify its formation and existence as a legal entity. The Escrow Agent may also ask to see financial statements, licenses, identification and authorization documents from individuals claiming authority to represent the entity or other relevant documentation. The Company agrees to provide all such information and documentation as requested by the Escrow Agent to ensure compliance with United States federal law.

(n) Force Majeure. In no event shall the Escrow Agent be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Escrow Agent shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

(o) Resignation or Removal of the Escrow Agent.

(i) The Company may remove the Escrow Agent at any time by giving to the Escrow Agent thirty (30) calendar days’ prior written notice. The Escrow Agent may resign at any time by giving to the Company and the Trustee fifteen (15) calendar days’ prior written notice thereof.

(ii) Within ten (10) calendar days after giving the foregoing notice of removal to the Escrow Agent or receiving the foregoing notice of resignation from the Escrow Agent, the Company shall appoint a successor Escrow Agent. If a successor Escrow Agent has not accepted such appointment by the end of such 10-day period, the Escrow Agent may apply to a court of competent jurisdiction for the appointment of a successor Escrow Agent or for other appropriate relief. The costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Escrow Agent in connection with such proceeding shall be paid by the Company.

(iii) Upon receipt of the identity of the successor Escrow Agent, the Escrow Agent shall either deliver the Escrow Funds then held hereunder to the successor Escrow Agent, less the Escrow Agent’s fees, costs and expenses or other obligations owed to the Escrow Agent, or hold such Escrow Funds (or any portion thereof), pending distribution, until all such fees, costs and expenses or other obligations are paid.

(iv) Upon delivery of the Escrow Funds to successor Escrow Agent, the Escrow Agent shall have no further duties, responsibilities or obligations hereunder.

(p) Trustee. The parties hereto agree that the Trustee shall be entitled to all of the rights, protections, privileges, indemnities and immunities afforded to the Trustee under the Indenture in connection with its execution of this Agreement and performance of its obligations hereunder.

(q) Shareholder Communication Act, Etc. With respect to securities issued in the United States, the Shareholders Communications Act of 1985 (the “Act”) requires the Escrow Agent to disclose to issuers, upon their request, the name, address and securities position of entities who are (a) the “beneficial owners” (as defined in the Act) of the issuer’s securities, if the beneficial owner does not object to such disclosure, or (b) acting as a “respondent bank” (as defined in the Act) with respect to the securities. (Under the Act, “respondent banks” do not have the option of objecting to such disclosure upon the issuers’ request.) The Act defines a “beneficial owner” as any person who has, or shares, the power to vote a security (pursuant to an agreement or otherwise), or who directs the voting of a security. The Act defines a “respondent bank” as any bank, association or other entity that exercises fiduciary powers which holds securities on behalf of beneficial owners and deposits such securities for safekeeping with a bank, such as the Escrow Agent. Under the Act, the Company is either the “beneficial owner” of the Securities to be held in escrow or a “respondent bank.”

¨ The Company is the “beneficial owner,” as defined in the Act, of the securities to be held by the Escrow Agent hereunder.

¨ The Company is not the beneficial owner of the securities to be held by the Escrow Agent, but is acting as a “respondent bank,” as defined in the Act, with respect to the securities to be held by the Escrow Agent hereunder.

IF NO BOX IS CHECKED, THE ESCROW AGENT SHALL ASSUME THAT THE COMPANY IS THE BENEFICIAL OWNER OF THE SECURITIES.

For beneficial owners of the securities only:

¨ Company objects

¨ Company does not object

to the disclosure of its name, address and securities position to any issuer which requests such information pursuant to the Act for the specific purpose of direct communications between such issuer and the Company.

IF NO BOX IS CHECKED, THE ESCROW AGENT SHALL RELEASE SUCH INFORMATION UNTIL IT RECEIVES A CONTRARY WRITTEN INSTRUCTION FROM THE COMPANY.

With respect to securities issued outside of the United States, information shall be released to issuers only if required by law or regulation of the particular country in which the securities are located.

The Company agrees to disseminate in a timely manner any proxies or requests for voting instructions, other proxy soliciting material, information statements, and/or annual reports that it receives to any other beneficial owners.

(r) Information Sharing. The Bank of New York Mellon Corporation is a global financial organization that provides services to clients through its affiliates and subsidiaries in multiple jurisdictions (the “BNY Mellon Group”). The BNY Mellon Group may centralize functions including audit, accounting, risk, legal, compliance, sales, administration, product communication, relationship management, storage, compilation and analysis of customer-related data, and other functions (the “Centralized Functions”) in one or more affiliates, subsidiaries and third-party service providers. Notwithstanding anything contained elsewhere in this Agreement, the Company consents to the disclosure of and authorizes the Escrow Agent to disclose information regarding the Company to the BNY Mellon Group and to its third-party service providers who are subject to confidentiality obligations with respect to such information, in connection with the Centralized Functions. In addition, the BNY Mellon Group may aggregate the Company’s data with other data collected and/or calculated by the BNY Mellon Group and the BNY Mellon Group will own all such aggregated data, provided that the BNY Mellon Group shall not distribute the aggregated data in a format that identifies the Company or the Company’s data with the Company. In addition, the BNY Mellon Group may store the names and business addresses of the Company’s employees on the systems or in the records of the BNY Mellon Group or its service providers for purposes of the Centralized Functions, and the Company consents and is authorized to consent to such storage and confirms that the disclosure to and storage by the BNY Mellon Group of such information does not violate any relevant data protection legislation.

(s) Authorized Persons. Each of the Company and the Trustee shall, on the date of this Agreement, deliver to the other parties a certificate in the form of Schedule I hereto as to the incumbency and specimen signature of at least two (2) officers or other representatives of such party authorized to act for and give and receive notices, requests and instructions on behalf of such party in connection with this Agreement (each such officer or other representative, an “Authorized Person”). From time to time, the Company or Trustee, as applicable, may, by delivering to the other parties a revised certificate in the form of Annex B, change the information previously given, but each of the parties hereto shall be entitled to rely conclusively on the then-current schedule until receipt of a superseding schedule.
