If any provision of this Second Supplemental Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provisions shall be deemed to apply to the Indenture as so modified or excluded, as the case may be.

Except as otherwise required by Section 22 of the Notes, the Company hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The Borough of Manhattan, New York, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is

This Series B-2 Senior Convertible Note Due 2024 (including all Senior Convertible Notes issued in exchange, transfer or replacement hereof, this “Note”) is one of an issue of Senior Convertible Notes (collectively, the “Notes”, and such other Senior Convertible Notes, the “Other Notes”) issued pursuant to (i) Section 1 of that certain Securities Purchase Agreement, dated as of December 30, 2022, by and among the Company and the investors (the “Buyers”) referred to therein, as amended from time to time (the “Securities Purchase Agreement”), (ii) the Indenture, (iii) a Supplemental Indenture, and (iv) the Company’s Registration Statement on Form S-3 (File number 333-264068 ) (the “Registration Statement”). Certain capitalized terms used herein are defined in Section 31.

ARTICLE I.PAYMENTS OF PRINCIPAL. On the Maturity Date, the Company shall pay to the Holder an amount in cash representing all outstanding Principal, accrued and unpaid Interest on such outstanding Principal and accrued and unpaid Late Charges (as defined in Section 23(c)) on such Principal and Interest. Other than as specifically permitted or required by this Note, the Company may not prepay any portion of the outstanding Principal, Make-Whole Amount, accrued and unpaid Interest or accrued and unpaid Late Charges on Principal, Make-Whole Amount and Interest, if any. Notwithstanding anything herein to the contrary, with respect to any conversion or redemption hereunder, as applicable, the Company shall convert or redeem, as applicable, First, all accrued and unpaid Late Charges on any Principal and Interest hereunder and under any other Notes held by the Holder and all other amounts owed to the Holder under any other Transaction Document (as such term is defined in the Securities Purchase Agreement), Second, all accrued and unpaid Interest and Make-Whole Amount, if any, hereunder and under any Other Notes held by such Holder, Third, all other amounts (other than Principal) outstanding under any Other Notes held by such Holder and, Fourth, all Principal outstanding hereunder and under any Other Notes held by such Holder, in each case, allocated pro rata among this Note and such Other Notes held by such Holder.

ARTICLE II.INTEREST; INTEREST RATE.

(1)Interest on this Note shall commence accruing on the Issuance Date and shall be computed on the basis of a 360-day year consisting of twelve 30-day months and shall

be payable in arrears on the first calendar day of each calendar quarter (each, an “Interest Date”) with the first Interest Date being July 1, 2023. Interest shall be payable on each Interest Date, to the record holder of this Note on the applicable Interest Date, in shares of Common Stock (“Interest Shares”) so long as there has been no Equity Conditions Failure; provided, however, that the Company may, at its option following notice to the Holder, pay Interest on any Interest Date in cash (“Cash Interest”) or in a combination of Cash Interest and Interest Shares. The Company shall deliver a written notice (each, an “Interest Election Notice”) to each holder of the Notes on or prior to the tenth (10th) Trading Day immediately prior to the applicable Interest Date (each, an “Interest Notice Due Date”) (the date such notice is delivered to all of the holder, the “Interest Notice Date”) which notice (i) either (A) confirms that Interest to be paid on such Interest Date shall be paid entirely in Interest Shares or (B) elects to pay Interest as Cash Interest or a combination of Cash Interest and Interest Shares and specifies the amount of Interest that shall be paid as Cash Interest and the amount of Interest, if any, that shall be paid in Interest Shares and (ii) if such Interest payment includes Interest Shares, certifies that there has been no Equity Conditions Failure as of the Interest Notice Date; provided, however, that the Company shall be deemed to have certified that no Equity Conditions Failure exists if the Company does not deliver any notice to the contrary. If an Equity Conditions Failure has occurred as of the Interest Notice Date, then unless the Company has elected to pay such Interest as Cash Interest, the Interest Election Notice shall indicate that unless the Holder waives the Equity Conditions Failure, the Interest shall be paid as Cash Interest. Notwithstanding anything herein to the contrary, if no Equity Conditions Failure has occurred as of the Interest Notice Date but an Equity Conditions Failure subsequently occurs at any time prior to the applicable Interest Date, (A) the Company shall provide the Holder a subsequent notice to that effect and (B) unless the Holder waives the Equity Conditions Failure, the Interest shall be paid in cash. Interest to be paid on an Interest Date in Interest Shares shall be paid in a number of fully paid and nonassessable shares (rounded to the nearest whole share in accordance with Section 3(a)) of Common Stock equal to the quotient of (1) the amount of Interest payable on such Interest Date less any Cash Interest paid and (2) the Interest Conversion Price in effect on the applicable Interest Date.

(2)When any Interest Shares are to be paid on an Interest Date, the Company shall (A) provided that the Company’s transfer agent (the “Transfer Agent”) is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program (“FAST”), credit such aggregate number of Interest Shares to which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system, or (B) if the Transfer Agent is not participating in FAST, issue and deliver on the applicable Interest Date, to the address set forth in the register maintained by the Company for such purpose pursuant to the Securities Purchase Agreement or to such address as specified by the Holder in writing to the Company at least two (2) Business Days prior to the applicable Interest Date, a certificate, registered in the name of the Holder or its designee, for the number of Interest Shares to which the Holder shall be entitled. Any Cash Interest payable on an Interest Date shall be paid to the Holder in accordance with Section 23(c).

(3)Prior to the payment of Interest on an Interest Date, Interest on this Note shall accrue at the Interest Rate and be payable by way of inclusion of the Interest in the Conversion Amount on each Conversion Date in accordance with Section 3(b)(i) or upon any redemption in accordance with Section 10 or any required payment upon any Bankruptcy Event of Default. From and after the occurrence and during the continuance of any Event of Default, the Interest Rate in effect with respect to such determination shall automatically be increased to twelve and a half percent (12.5%) per annum (the “Default Rate”). In the event that such Event of Default is subsequently cured (and no other Event of Default then exists, including, without limitation, for the Company’s failure to pay such Interest at the Default Rate on the applicable Interest Date), the adjustment referred to in the preceding sentence shall cease to be effective as

of the calendar day immediately following the date of such cure; provided that the Interest as calculated and unpaid at such increased rate during the continuance of such Event of Default shall continue to apply to the extent relating to the days after the occurrence of such Event of Default through and including the date of such cure of such Event of Default.

ARTICLE III.CONVERSION OF NOTES. At any time on or after the date hereof, this Note shall be convertible into validly issued, fully paid and non-assessable shares of Common Stock (as defined below), on the terms and conditions set forth in this Section 3.

(1)Conversion Right. Subject to the provisions of Section 3(d), at any time or times on or after the date hereof, the Holder shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount (as defined below) into validly issued, fully paid and non-assessable shares of Common Stock in accordance with Section 3(c), at the Conversion Rate (as defined below). The Company shall not issue any fraction of a share of Common Stock upon any conversion. If the issuance would result in the issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock up to the nearest whole share. The Company shall pay any and all transfer, stamp, issuance and similar taxes, costs and expenses (including, without limitation, fees and expenses of the Transfer Agent (as defined below)) that may be payable with respect to the issuance and delivery of Common Stock upon conversion of any Conversion Amount.

(2)Conversion Rate. The number of shares of Common Stock issuable upon conversion of any Conversion Amount pursuant to Section 3(a) shall be determined by dividing (x) such Conversion Amount by (y) the Conversion Price (the “Conversion Rate”).

(3)Mechanics of Conversion.

(a)Optional Conversion. To convert any Conversion Amount into shares of Common Stock on any date (a “Conversion Date”), the Holder shall deliver (whether via electronic mail or otherwise), for receipt on or prior to 11:59 p.m., New York time, on such date, a copy of an executed notice of conversion in the form attached hereto as Exhibit I (each, a “Conversion Notice”) to the Company and the Trustee. If required by Section 3(c)(iii), within two (2) Trading Days following a conversion of this Note as aforesaid, the Holder shall surrender this Note to a nationally recognized overnight delivery service for delivery to the Company (or an indemnification undertaking with respect to this Note in the case of its loss, theft or destruction as contemplated by Section 17(b)). On or before the first (1st) Trading Day following the date of receipt of a Conversion Notice, the Company shall transmit by electronic mail an acknowledgment, in the form attached hereto as Exhibit II, of confirmation of receipt of such Conversion Notice (each, an “Initial Acknowledgement”) to the Holder, the Trustee and the Transfer Agent which confirmation shall constitute an instruction to the Transfer Agent to process such Conversion Notice in accordance with the terms herein. On or before the second (2nd) Trading Day following the date on which the Company has received a Conversion Notice (or such earlier date as required pursuant to the 1934 Act or other applicable law, rule or regulation for the settlement of a trade initiated on the applicable Conversion Date of such shares of Common Stock issuable pursuant to such Conversion Notice) (each, an “Initial Share Delivery Deadline”), whether or not the Company shall have delivered an Acknowledgment with respect thereto, the Company shall (1) provided that the Transfer Agent is participating in FAST, credit such aggregate number of shares of Common Stock equal to the quotient of (x) the

applicable Conversion Amount, divided by (y) the applicable Conversion Base Price then in effect (each, a “Base Conversion Share”) to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system or (2) if the Transfer Agent is not participating in FAST, upon the request of the Holder, issue and deliver (via reputable overnight courier) to the address as specified in the Conversion Notice, a certificate, registered in the name of the Holder or its designee, for such Base Conversion Shares. On or before the second (2nd) Trading Day following the end of the Conversion Measuring Period, if the Holder has not elected in such Conversion Notice to waive the right to make a Remainder Eligible Election with respect to such Conversion Notice, the Holder shall deliver a written notice to the Company, the Trustee and the Transfer Agent with respect to the remaining shares of Common Stock, if any, to be issued to the Holder in such conversion in the form attached hereto as Exhibit III (each, a “Remainder Conversion Notice”). On or before the first (1st) Trading Day following the date of receipt of a Remainder Conversion Notice, the Company shall transmit by electronic mail an acknowledgment, in the form attached hereto as Exhibit IV, of confirmation of receipt of such Conversion Notice (each, an “Additional Acknowledgement”, and together with each Initial Acknowledgement, each an “Acknowledgment”) to the Holder, the Trustee and the Transfer Agent which confirmation shall constitute an instruction to the Transfer Agent to process such Conversion Notice in accordance with the terms herein. On or prior to the second (2nd) Trading Day following the date on which the Company has received a Remainder Conversion Notice (each, an “Additional Share Delivery Deadline”, and together with each Initial Share Delivery Deadline, each a “Share Delivery Deadline”), the Company shall deliver to the Holder such number of additional shares of Common Stock, if any, equal to the difference of (I) the quotient of (x) the applicable Conversion Amount, divided by (y) the applicable Conversion Price less (II) the aggregate number of applicable Base Conversion Shares with respect thereto (each, a “Remaining Conversion Share”); provided, that in the event of the Conversion Price Floor Condition, on or prior to the fourth (4th) Trading Day after applicable Conversion Date (or, if later, the applicable Additional Share Delivery Deadline, if any), the Company shall also deliver to the Holder the applicable Conversion Floor Amount (which, for the avoidance of doubt, shall not include any cash payment with respect to any Exchange Cap Shares (as defined below) and shall not be in duplication of any Exchange Cap Amount (as defined below)). If this Note is physically surrendered for conversion pursuant to Section 3(c)(iii) and the outstanding Principal of this Note is greater than the Principal portion of the Conversion Amount being converted, then the Company shall as soon as reasonably practicable and in no event later than two (2) Business Days after receipt of this Note and at its own expense, issue and deliver to the Holder (or its designee) a new Note (in accordance with Section 17(d)) representing the outstanding Principal (and accrued and unpaid Interest and Make-Whole Amount thereon) not converted. The Person or Persons entitled to receive the shares of Common Stock issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such shares of Common Stock on the Conversion Date.

(b)Company’s Failure to Timely Convert. If on or prior to the Share Delivery Deadline (A) if the Transfer Agent is not participating in FAST, the Company shall fail to issue and deliver to the Holder (or its designee) a certificate and register such shares of Common Stock on the Company’s share register or (B) if the Transfer Agent is participating in FAST, the Transfer Agent shall fail to credit the balance account of the Holder or the Holder’s designee with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s conversion hereunder or pursuant to the Company’s obligation pursuant to clause (II)

below (collectively, a “Conversion Failure”), and if on or after such Share Delivery Deadline the Holder acquires (in an open market transaction, stock loan or otherwise) shares of Common Stock corresponding to all or any portion of the number of shares of Common Stock issuable upon such conversion that the Holder is entitled to receive from the Company and has not received from the Company in connection with (or as a result of) such Conversion Failure (a “Buy-In”), then, in addition to all other remedies available to the Holder, the Company shall, within two (2) Business Days after receipt of the Holder’s request and in the Holder’s discretion, either: (I) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions, stock loan costs and other out-of-pocket expenses, if any) for the shares of Common Stock so acquired (including, without limitation, by any other Person in respect, or on behalf, of the Holder) (the “Buy-In Price”), at which point the Company’s obligation to so issue and deliver such certificate (and to issue such shares of Common Stock) or credit the balance account of such Holder or such Holder’s designee, as applicable, with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s conversion hereunder (as the case may be) (and to issue such shares of Common Stock) shall terminate, or (II) promptly honor its obligation to so issue and deliver to the Holder a certificate or certificates representing such shares of Common Stock or credit the balance account of such Holder or such Holder’s designee, as applicable, with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s conversion hereunder (as the case may be) and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (x) such number of shares of Common Stock multiplied by (y) the lowest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date of the applicable Conversion Notice and ending on the date of such issuance and payment under this clause (II) (the “Buy-In Payment Amount”). Nothing shall limit the Holder’s right to pursue any other remedies available to it hereunder, at law or in equity, including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing shares of Common Stock (or to electronically deliver such shares of Common Stock) upon the conversion of this Note as required pursuant to the terms hereof.

(c)Registration; Book-Entry. The Trustee shall maintain a register (the “Register”) for the recordation of the names and addresses of the holders of each Note and the principal amount of the Notes held by such holders (the “Registered Notes”) as provided in Section 2.11 of the Supplemental Indenture. The entries in the Register shall be conclusive and binding for all purposes absent manifest error. The Company and the holders of the Notes shall treat each Person whose name is recorded in the Register as the owner of a Note for all purposes (including, without limitation, the right to receive payments of Principal, Make-Whole Amount and Interest hereunder) notwithstanding notice to the contrary. A Registered Note may be assigned, transferred or sold in whole or in part only by registration of such assignment or sale on the Register. Upon its receipt of a written request to assign, transfer or sell all or part of any Registered Note by the holder thereof, the Trustee shall record the information contained therein in the Register and issue one or more new Registered Notes in the same aggregate principal amount as the principal amount of the surrendered Registered Note to the designated assignee or transferee pursuant to Section 16, provided that if the Company does not so record an assignment, transfer or sale (as the case may be) of all or part of any Registered Note within two (2) Business Days of such a request, then the Register shall be automatically deemed updated to reflect such assignment, transfer or sale (as the case may be).

Notwithstanding anything to the contrary set forth in this Section 2 or in the Indenture or in any applicable Supplemental Indenture, following conversion of any portion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Company unless (A) the full Conversion Amount represented by this Note is being converted (in which event this Note shall be delivered to the Company following conversion thereof as contemplated by Section 3(c)(i)) or (B) the Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting reissuance of this Note upon physical surrender of this Note. The Holder, the Trustee and the Company shall maintain records showing the Principal, Make-Whole Amount, Interest and Late Charges converted and/or paid (as the case may be) and the dates of such conversions, and/or payments (as the case may be) or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this Note upon conversion. If the Company does not update the Register to record such Principal, Make-Whole Amount, Interest and Late Charges converted and/or paid (as the case may be) and the dates of such conversions, and/or payments (as the case may be) within two (2) Business Days of such occurrence, then the Register shall be automatically deemed updated to reflect such occurrence. Any Holder that sells a participation in this Note shall, acting solely for this purpose as a non-fiduciary agent of the Company, maintain a register substantially similar to the Register on which it enters the name and address of each participant and the principal amounts (and stated interest) of each participant’s interest in the participated Notes (the “Participant Register”); provided such Holder shall have no obligation to disclose all or any portion of the Participant Register (including the identity of any participant) to the Company except to the extent that such disclosure is necessary to establish that the Note is in registered form under Treasury Regulations Section 5f.103-1(c). The entries in the Participant Register shall be conclusive and binding absent manifest error, and Holder shall treat the Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Note notwithstanding any notice to the contrary. This Section 3(c)(iii) shall be construed so that the Note is at all times maintained in “registered form” within the meaning of Internal Revenue Code of 1986, as amended (the “IRC”) Sections 163(f), 871(h)(2) and 881(c)(2) and any related regulations (or any successor provisions of the IRC or such regulations).

(d)Pro Rata Conversion; Disputes. In the event that the Company receives a Conversion Notice from more than one holder of Notes for the same Conversion Date and the Company can convert some, but not all, of such portions of the Notes submitted for conversion, the Company, subject to Section 3(d), shall convert from each holder of Notes electing to have Notes converted on such date a pro rata amount of such holder’s portion of its Notes submitted for conversion based on the principal amount of Notes submitted for conversion on such date by such holder relative to the aggregate principal amount of all Notes submitted for conversion on such date. In the event of a dispute as to the number of shares of Common Stock issuable to the Holder in connection with a conversion of this Note, the Company shall issue to the Holder the number of shares of Common Stock not in dispute and resolve such dispute in accordance with Section 22.

(4)Limitations on Conversions.

(a)Beneficial Ownership. The Company shall not effect the conversion of any portion of this Note, and the Holder shall not have the right to convert any portion of this Note pursuant to the terms and conditions of this Note and

any such conversion shall be null and void and treated as if never made, to the extent that after giving effect to such conversion, the Holder together with the other Attribution Parties collectively would beneficially own in excess of 4.99% (the “Maximum Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such conversion. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by the Holder and the other Attribution Parties shall include the number of shares of Common Stock held by the Holder and all other Attribution Parties plus the number of shares of Common Stock issuable upon conversion of this Note with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be issuable upon (A) conversion of the remaining, nonconverted portion of this Note beneficially owned by the Holder or any of the other Attribution Parties and (B) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any convertible notes or convertible preferred stock or warrants) beneficially owned by the Holder or any other Attribution Party subject to a limitation on conversion or exercise analogous to the limitation contained in this Section 3(d)(i). For purposes of this Section 3(d)(i), beneficial ownership shall be calculated in accordance with Section 13(d) of the 1934 Act. For purposes of determining the number of outstanding shares of Common Stock the Holder may acquire upon the conversion of this Note without exceeding the Maximum Percentage, the Holder may rely on the number of outstanding shares of Common Stock as reflected in the most recent of (x) the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the SEC, as the case may be, (y) a more recent public announcement by the Company or (z) any other written notice by the Company or the Transfer Agent, if any, setting forth the number of shares of Common Stock outstanding (the “Reported Outstanding Share Number”). If the Company receives a Conversion Notice from the Holder at a time when the actual number of outstanding shares of Common Stock is less than the Reported Outstanding Share Number, the Company shall notify the Holder in writing of the number of shares of Common Stock then outstanding and, to the extent that such Conversion Notice would otherwise cause the Holder’s beneficial ownership, as determined pursuant to this Section 3(d)(i), to exceed the Maximum Percentage, the Holder must notify the Company of a reduced number of shares of Common Stock to be purchased pursuant to such Conversion Notice. For any reason at any time, upon the written or oral request of the Holder, the Company shall within one (1) Business Day confirm orally and in writing or by electronic mail to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Note, by the Holder and any other Attribution Party since the date as of which the Reported Outstanding Share Number was reported. In the event that the issuance of shares of Common Stock to the Holder upon conversion of this Note results in the Holder and the other Attribution Parties being deemed to beneficially own, in the aggregate, more than the Maximum Percentage of the number of outstanding shares of Common Stock (as determined under Section 13(d) of the 1934 Act), the number of shares so issued by which the Holder’s and the other Attribution Parties’ aggregate beneficial ownership exceeds the Maximum Percentage (the “Excess Shares”) shall be deemed null and void and shall be cancelled ab initio, and the Holder shall not have the power to vote or to transfer the Excess Shares. Upon delivery of a written notice to the Company, the Holder may from time to time increase (with such increase not effective until the sixty-first (61st) day after delivery of such notice) or decrease the Maximum Percentage to any other percentage not in excess of 9.99% as specified in such notice;

provided that (i) any such increase in the Maximum Percentage will not be effective until the sixty-first (61st) day after such notice is delivered to the Company and (ii) any such increase or decrease will apply only to the Holder and the other Attribution Parties and not to any other holder of Notes that is not an Attribution Party of the Holder. For purposes of clarity, the shares of Common Stock issuable pursuant to the terms of this Note in excess of the Maximum Percentage shall not be deemed to be beneficially owned by the Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the 1934 Act. No prior inability to convert this Note pursuant to this paragraph shall have any effect on the applicability of the provisions of this paragraph with respect to any subsequent determination of convertibility. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 3(d)(i) to the extent necessary to correct this paragraph (or any portion of this paragraph) which may be defective or inconsistent with the intended beneficial ownership limitation contained in this Section 3(d)(i) or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitation contained in this paragraph may not be waived and shall apply to a successor holder of this Note.

(b)Principal Market Regulation. The Company shall not issue any shares of Common Stock upon conversion of this Note or otherwise pursuant to the terms of this Note if the issuance of such shares of Common Stock would exceed the aggregate number of shares of Common Stock which the Company may issue upon conversion of the Notes or otherwise pursuant to the terms of this Note without breaching the Company’s obligations under the rules or regulations of the Principal Market (the number of shares which may be issued without violating such rules and regulations, including rules related to the aggregate of offerings under NASDAQ Listing Rule 5635(d), the “Exchange Cap”), except that such limitation shall not apply in the event that the Company (A) obtains the approval of its stockholders as required by the applicable rules of the Principal Market for issuances of shares of Common Stock in excess of such amount or (B) obtains a written opinion from counsel to the Company that such approval is not required, which opinion shall be reasonably satisfactory to the Holder. Until such approval or such written opinion is obtained, no Buyer shall be issued in the aggregate, upon conversion or exercise (as the case may be) of any Notes or otherwise pursuant to the terms of the Notes, shares of Common Stock in an amount greater than the product of (i) the Exchange Cap as of the Issuance Date multiplied by (ii) the quotient of (1) the original principal amount of Notes issued to such Buyer pursuant to the Securities Purchase Agreement on the Initial Closing Date (as defined in the Securities Purchase Agreement) divided by (2) the aggregate original principal amount of all Notes issued to the Buyers pursuant to the Securities Purchase Agreement on the Initial Closing Date (with respect to each Buyer, the “Exchange Cap Allocation”). In the event that any Buyer shall sell or otherwise transfer any of such Buyer’s Notes, the transferee shall be allocated a pro rata portion of such Buyer’s Exchange Cap Allocation with respect to such portion of such Notes so transferred, and the restrictions of the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation so allocated to such transferee. Upon conversion and exercise in full of a holder’s Notes, the difference (if any) between such holder’s Exchange Cap Allocation and the number of shares of Common Stock actually issued to such holder upon such holder’s conversion in full of such Notes shall be allocated, to the respective Exchange Cap Allocations of the remaining holders of Notes on a pro rata basis in proportion to the shares of Common Stock underlying the Notes then held by each such holder of Notes. At any time the Company is prohibited from issuing shares of Common Stock pursuant to this Section 3(d)(ii) (the “Exchange Cap

Shares”), the Company shall pay cash in exchange for the cancellation of such portion of this Note convertible into such Exchange Cap Shares at a price equal to the sum of (i) the product of (x) such number of Exchange Cap Shares and (y) the greater of (I) Closing Sale Price of the Common Stock on the applicable Conversion Date and (II) the greatest VWAP of the Common Stock on any of the three (3) Trading Days during the period commencing on, and including, such Conversion Date, and (ii) to the extent of any Buy-In related thereto (but without duplication with respect to the underlying Exchange Cap Shares), any Buy-In Payment Amount, any brokerage commissions and other out-of-pocket expenses, if any, of the Holder incurred in connection therewith (collectively, the “Exchange Cap Share Cancellation Amount”).

(5)Right of Alternate Conversion Upon an Event of Default.

(a)General. Subject to Section 3(d), at any time during an Event of Default Redemption Right Period (as defined below) (regardless of whether such Event of Default has been cured, or if the Company has delivered an Event of Default Notice to the Holder or if the Holder has delivered an Event of Default Redemption Notice to the Company or otherwise notified the Company that an Event of Default has occurred), the Holder may, at the Holder’s option, convert (each, an “Alternate Conversion”, and the date of such Alternate Event of Default Conversion, each, an “Alternate Conversion Date”) all, or any part of, the Conversion Amount (such portion of the Conversion Amount subject to such Alternate Conversion, the “Alternate Conversion Amount”) into shares of Common Stock at an alternate conversion rate equal to the quotient of (x) Redemption Premium of the Conversion Amount divided by (y) the Conversion Price.

(b)Mechanics of Alternate Conversion. On any Alternate Conversion Date, the Holder may voluntarily convert any Alternate Conversion Amount pursuant to Section 3(c) (with “Redemption Premium of the Conversion Amount” replacing “Conversion Amount” in clause (x) of the definition of Conversion Rate above with respect to such Alternate Conversion) by designating in the Conversion Notice delivered pursuant to this Section 3(e) of this Note that the Holder is electing an Alternate Conversion. Notwithstanding anything to the contrary in this Section 3(e), but subject to Section 3(d), until the Company delivers shares of Common Stock representing the applicable Alternate Conversion Amount to the Holder, such Alternate Conversion Amount may be converted by the Holder into shares of Common Stock pursuant to Section 3(c) without regard to this Section 3(e).

ARTICLE IV.RIGHTS UPON EVENT OF DEFAULT.

(1)Event of Default. Each of the following events shall constitute an “Event of Default” and each of the events in clauses (vi), (vii) and (viii) shall constitute a “Bankruptcy Event of Default”:

(a)the suspension from trading or the failure of the Common Stock to be trading or listed (as applicable) on an Eligible Market for a period of five (5) consecutive Trading Days;

(c)except to the extent the Company is in compliance with Section 9(b) below, at any time following the tenth (10th) consecutive day that the Holder’s Authorized Share Allocation (as defined in Section 9(a) below) is less than the number of shares of Common Stock that the Holder would be entitled to receive upon a conversion of the full Conversion Amount of this Note (without regard to any limitations on conversion set forth in Section 3(d) or otherwise);

(d)the Company’s failure to pay to the Holder any amount of Principal, Make-Whole Amount, Interest, Late Charges or other amounts when and as due under this Note (including, without limitation, the Company’s failure to pay any redemption payments or amounts hereunder) or any other Transaction Document or any other agreement, document, certificate or other instrument delivered in connection with the transactions contemplated hereby and thereby, except, in the case of a failure to pay any Make-Whole Amount, Interest, Late Charges or other amounts when and as due, in which case only if such failure remains uncured for a period of at least three (3) Trading Days;

(e)the Company fails to remove any restrictive legend on any certificate or any shares of Common Stock issued to the Holder upon conversion or exercise (as the case may be) of any Securities (as defined in the Securities Purchase Agreement) acquired by the Holder under the Securities Purchase Agreement (including this Note) as and when required by such Securities or the Securities Purchase Agreement, unless otherwise then prohibited by applicable federal securities laws, and any such failure remains uncured for at least five (5) days;

of any such action or the taking of any action by any Person to commence a Uniform Commercial Code foreclosure sale or any other similar action under federal, state or foreign law;

(j)default by the Company and/or any Subsidiary with respect to any Debt in excess of $30,000,000 (or its foreign currency equivalent) in the aggregate of the Company, and/or any such Subsidiary, whether such Debt now exists or shall hereafter be created (i) resulting in such Debt becoming or being declared due and payable prior to its stated maturity or (ii) constituting a failure to pay the principal of any such indebtedness when due and payable (after the expiration of all applicable grace periods) at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise and, in each such case, such indebtedness is not discharged, or such acceleration is not otherwise cured or rescinded within 30 days;

(2)Notice of an Event of Default; Redemption Right. Upon actual knowledge by the Company of the occurrence of an Event of Default with respect to this Note or any Other Note, the Company shall within one (1) Business Day deliver written notice thereof via electronic mail and overnight courier (with next day delivery specified) (an “Event of Default Notice”) to the Holder and the Trustee. The obligation of the Company to deliver an Event of Default Notice is in addition to, and may not be substituted by, the Trustee’s delivery of notice of the same Event of Default to the Holder in accordance with Section 602 of the Indenture. At any time after the earlier of the Holder’s receipt of an Event of Default Notice and the Holder becoming aware of an Event of Default (such earlier date, the “Event of Default Right Commencement Date”) and ending (such ending date, the “Event of Default Right Expiration Date”, and each such period, an “Event of Default Redemption Right Period”) on the twentieth (20th) Trading Day after the later of (x) the date such Event of Default is cured and (y) the Holder’s receipt of an Event of Default Notice that includes (I) a reasonable description of the applicable Event of Default, (II) a certification as to whether, in the opinion of the Company, such Event of Default is capable of being cured and, if applicable, a reasonable description of any existing plans of the Company to cure such Event of Default and (III) a certification as to the date the Event of Default occurred and, if cured on or prior to the date of such Event of Default Notice, the applicable Event of Default Right Expiration Date, the Holder may require the Company to redeem (regardless of whether such Event of Default has been cured on or prior to the Event of Default Right Expiration Date) all or any portion of this Note by delivering written notice thereof (the “Event of Default Redemption Notice”) to the Company and the Trustee which Event of Default Redemption Notice shall indicate the portion of this Note the Holder is electing to redeem. Each portion of this Note subject to redemption by the Company pursuant to this Section 4(b) shall be redeemed by the Company at a price equal to the greater of (i) the product of (A) the Conversion Amount to be redeemed multiplied by (B) the Redemption Premium and (ii) the product of (X) the Conversion Rate (calculated assuming an Alternate Conversion as of the date of the Event of Default Redemption Notice) with respect to the Conversion Amount in effect at such time as the Holder delivers an Event of Default Redemption Notice multiplied by (Y) the product of (1) the Redemption Premium multiplied by (2) the greatest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date immediately preceding such Event of Default and ending on the Trading Day immediately prior to the date the Company makes the entire payment required to be made under this Section 4(b) (the “Event of Default Redemption Price”). Redemptions required by this Section 4(b) shall be made in accordance with the provisions of Section 10. To the extent redemptions required by this Section 4(b) are deemed or determined by a court of competent jurisdiction to be prepayments of this Note by the Company, such redemptions shall be deemed to be voluntary prepayments. Notwithstanding anything to the contrary in this Section 3(e), but subject to Section 3(d), until the Event of Default Redemption Price (together with any Late Charges thereon) is paid in full, the Conversion Amount submitted for redemption under this Section 4(b) (together with any Late Charges thereon) may be converted, in whole or in part, by the Holder into Common Stock pursuant to the terms of this Note and any such Conversion Amount converted (whether by Alternate Conversion or otherwise) shall reduce the Event of Default Redemption Price hereunder on a dollar-for-dollar basis. In the event of the Company’s redemption of

any portion of this Note under this Section 4(b), the Holder’s damages would be uncertain and difficult to estimate because of the parties’ inability to predict future interest rates and the uncertainty of the availability of a suitable substitute investment opportunity for the Holder. Accordingly, any redemption premium due under this Section 4(b) is intended by the parties to be, and shall be deemed, a reasonable estimate of the Holder’s actual loss of its investment opportunity and not as a penalty. Any redemption upon an Event of Default shall not constitute an election of remedies by the Holder, and all other rights and remedies of the Holder shall be preserved.

(3)Mandatory Redemption upon Bankruptcy Event of Default. Notwithstanding anything to the contrary herein, and notwithstanding any conversion that is then required or in process, upon any Bankruptcy Event of Default, whether occurring prior to or following the Maturity Date, the Company shall immediately pay to the Holder an amount in cash representing (i) all outstanding Principal, Make-Whole Amount, accrued and unpaid Interest and accrued and unpaid Late Charges on such Principal, Make-Whole Amount and Interest, multiplied by (ii) the Redemption Premium, in addition to any and all other amounts due hereunder, without the requirement for any notice or demand or other action by the Holder or any other person or entity, provided that the Holder may, in its sole discretion, waive such right to receive payment upon a Bankruptcy Event of Default, in whole or in part, and any such waiver shall not affect any other rights of the Holder hereunder, including any other rights in respect of such Bankruptcy Event of Default, any right to conversion, and any right to payment of the Event of Default Redemption Price or any other Redemption Price, as applicable.

ARTICLE V.RIGHTS UPON FUNDAMENTAL TRANSACTION.

(1)Assumption. The Company shall not enter into or be party to a Fundamental Transaction unless (i) the Successor Entity (if other than the Company) assumes in writing all of the obligations of the Company under this Note and the other Transaction Documents in accordance with the provisions of this Section 5(a) (which written assumption document shall be subject to the approval, not to be unreasonably withheld, of the Required Holders prior to such Fundamental Transaction), and delivers to each holder of Notes in exchange for such Notes a security of the Successor Entity (substantially similar to the Notes in all material respects) and evidenced by a written instrument in form and substance reasonably satisfactory to the Required Holders, including, without limitation, having a principal amount and interest rate equal to the principal amounts then outstanding and the interest rates of the Notes held by such holder, having similar conversion rights as the Notes and having similar ranking to the Notes and (ii) the Successor Entity (or Parent Entity, as applicable) (if other than the Company) is a publicly traded corporation whose common stock (or the equivalent) is quoted on or listed for trading on an Eligible Market. Upon the occurrence of any Fundamental Transaction, the Successor Entity (if other than the Company) shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Note and the other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity (if other than the Company)), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Note and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of a Fundamental Transaction, the Successor Entity (if other than the Company) shall deliver to the Holder confirmation that there shall be issued upon conversion or redemption of this Note at any time after the consummation of such Fundamental Transaction, in lieu of the shares of Common Stock (or other securities, cash, assets or other property (except such items still issuable under Sections 6 and 14,

which shall continue to be receivable thereafter)) issuable upon the conversion or redemption of the Notes prior to such Fundamental Transaction, such shares of the publicly traded common stock (or their equivalent) of the Successor Entity (or its Parent Entity, as applicable) (if other than the Company) which the Holder would have been entitled to receive upon the happening of such Fundamental Transaction had this Note been converted immediately prior to such Fundamental Transaction (without regard to any limitations on the conversion of this Note), as adjusted in accordance with the provisions of this Note. Notwithstanding the foregoing, the Holder may elect, at its sole option, by delivery of written notice to the Company to waive this Section 5(a) to permit the Fundamental Transaction without the assumption of this Note. The provisions of this Section 5 shall apply similarly and equally to successive Fundamental Transactions and shall be applied without regard to any limitations on the conversion of this Note.

(2)Notice of a Change of Control; Redemption Right. No later than ten (10) Trading Days prior to the expected consummation of a Change of Control (the “Change of Control Date”), but not prior to the public announcement of such Change of Control, the Company shall deliver written notice thereof via electronic mail or overnight courier to the Holder and the Trustee (a “Change of Control Notice”). At any time during the period beginning after the Holder’s receipt of a Change of Control Notice or the Holder becoming aware of a Change of Control if a Change of Control Notice is not delivered to the Holder in accordance with the immediately preceding sentence (as applicable) and ending on twenty (20) Trading Days after the later of (A) the date of consummation of such Change of Control or (B) the date of receipt of such Change of Control Notice or (C) the date of the public announcement of such Change of Control, the Holder may require the Company to redeem all or any portion of this Note by delivering written notice thereof (“Change of Control Redemption Notice”) to the Company and the Trustee, which Change of Control Redemption Notice shall indicate the Conversion Amount the Holder is electing to redeem. The portion of this Note subject to redemption pursuant to this Section 5 shall be redeemed by the Company in cash at a price equal to the greatest of (i) the product of (w) the Change of Control Redemption Premium multiplied by (y) the Conversion Amount being redeemed, (ii) the product of (x) the Change of Control Redemption Premium multiplied by (y) the product of (A) the Conversion Amount being redeemed multiplied by (B) the quotient determined by dividing (I) the greatest Closing Sale Price of the shares of Common Stock during the period beginning on the date immediately preceding the earlier to occur of (1) the consummation of the applicable Change of Control and (2) the public announcement of such Change of Control and ending on the date the Holder delivers the Change of Control Redemption Notice by (II) the Conversion Price then in effect and (iii) the product of (y) the Change of Control Redemption Premium multiplied by (z) the product of (A) the Conversion Amount being redeemed multiplied by (B) the quotient of (I) the aggregate cash consideration and the aggregate cash value of any non-cash consideration per share of Common Stock to be paid to the holders of the shares of Common Stock upon consummation of such Change of Control (any such non-cash consideration constituting publicly-traded securities shall be valued at the highest of the Closing Sale Price of such securities as of the Trading Day immediately prior to the consummation of such Change of Control, the Closing Sale Price of such securities on the Trading Day immediately following the public announcement of such proposed Change of Control and the Closing Sale Price of such securities on the Trading Day immediately prior to the public announcement of such proposed Change of Control) divided by (II) the Conversion Price then in effect (the “Change of Control Redemption Price”). Redemptions required by this Section 5 shall be made in accordance with the provisions of Section 10 and shall have priority to payments to stockholders in connection with such Change of Control. To the extent redemptions required by this Section 5(b) are deemed or determined by a court

of competent jurisdiction to be prepayments of this Note by the Company, such redemptions shall be deemed to be voluntary prepayments. Notwithstanding anything to the contrary in this Section 5, but subject to Section 3(d), until the Change of Control Redemption Price (together with any Late Charges thereon) is paid in full, the Conversion Amount submitted for redemption under this Section 5(b) (together with any Late Charges thereon) may be converted, in whole or in part, by the Holder into Common Stock pursuant to Section 3. In the event of the Company’s redemption of any portion of this Note under this Section 5(b), the Holder’s damages would be uncertain and difficult to estimate because of the parties’ inability to predict future interest rates and the uncertainty of the availability of a suitable substitute investment opportunity for the Holder. Accordingly, any redemption premium due under this Section 5(b) is intended by the parties to be, and shall be deemed, a reasonable estimate of the Holder’s actual loss of its investment opportunity and not as a penalty.

ARTICLE VI.RIGHTS UPON ISSUANCE OF PURCHASE RIGHTS AND OTHER CORPORATE EVENTS.

(1)Purchase Rights. In addition to any adjustments pursuant to Sections 7 or 14 below, if at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to all or substantially all of the record holders of any class of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of this Note (without taking into account any limitations or restrictions on the convertibility of this Note and assuming for such purpose that the Note was converted at the Conversion Price as of the applicable record date) immediately prior to the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, that to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Purchase Right to the extent of the Maximum Percentage (and shall not be entitled to beneficial ownership of such shares of Common Stock as a result of such Purchase Right (and beneficial ownership) to the extent of any such excess) and such Purchase Right to such extent shall be held in abeyance (and, if such Purchase Right has an expiration date, maturity date or other similar provision, such term shall be extended by such number of days held in abeyance, if applicable) for the benefit of the Holder until such time or times, if ever, as its right thereto would not result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, at which time or times the Holder shall be granted such right (and any Purchase Right granted, issued or sold on such initial Purchase Right or on any subsequent Purchase Right held similarly in abeyance (and, if such Purchase Right has an expiration date, maturity date or other similar provision, such term shall be extended by such number of days held in abeyance, if applicable)) to the same extent as if there had been no such limitation).

(2)Other Corporate Events. In addition to and not in substitution for any other rights hereunder, prior to the consummation of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make appropriate provision to ensure that the Holder will thereafter have the right to receive upon a conversion of this Note, at the Holder’s option

(i) in addition to the shares of Common Stock receivable upon such conversion, such securities or other assets to which the Holder would have been entitled with respect to such shares of Common Stock had such shares of Common Stock been held by the Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility of this Note) or (ii) in lieu of the shares of Common Stock otherwise receivable upon such conversion, such securities or other assets received by the holders of shares of Common Stock in connection with the consummation of such Corporate Event in such amounts as the Holder would have been entitled to receive had this Note initially been issued with conversion rights for the form of such consideration (as opposed to shares of Common Stock) at a conversion rate for such consideration commensurate with the Conversion Rate. Provision made pursuant to the preceding sentence shall be in a form and substance reasonably satisfactory to the Required Holders. The provisions of this Section 6 shall apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations on the conversion or redemption of this Note.

ARTICLE VII.RIGHTS UPON ISSUANCE OF OTHER SECURITIES.

(1)[Intentionally Omitted]

(2)Adjustment of Reference Price upon Subdivision or Combination of Common Stock. Without limiting any provision of Section 6 or Section 14, if the Company at any time on or after the Subscription Date subdivides (by any stock split, stock dividend, stock combination, recapitalization or other similar transaction) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Reference Price in effect immediately prior to such subdivision will be proportionately reduced. Without limiting any provision of Section 6 or Section 14, if the Company at any time on or after the Subscription Date combines (by any stock split, stock dividend, stock combination, recapitalization or other similar transaction) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Reference Price in effect immediately prior to such combination will be proportionately increased. Any adjustment pursuant to this Section 7(b) shall become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment under this Section 7(b) occurs during the period that a Reference Price is calculated hereunder, then the calculation of such Reference Price shall be adjusted appropriately to reflect such event.

(3)Holder’s Right of Adjusted Conversion Price. In addition to and not in limitation of the other provisions of this Section 7 or in the Securities Purchase Agreement, if the Company in any manner issues or sells or enters into any agreement to issue or sell, any Common Stock, Options or Convertible Securities (other than with respect to a Permitted ATM or the Permitted Equity Lines (each as defined in the Securities Purchase Agreement)) or additional Notes pursuant to the Securities Purchase Agreement (or, for the avoidance of doubt, the Company’s 8.00% / 11.00% Convertible Senior PIK Toggle Notes due 2026 (the “2026 Notes”)) (any such securities, “Variable Price Securities”) regardless of whether securities have been sold pursuant to such agreement and whether such agreement has subsequently been terminated, prior to or after the Subscription Date that are issuable pursuant to such agreement or convertible into or exchangeable or exercisable for shares of Common Stock, in each case, at a price which varies or may vary with the market price of the shares of Common Stock, including by way of one or more reset(s) to a fixed price, but exclusive of such formulations reflecting customary anti-dilution provisions (such as share splits, share combinations, share dividends and similar transactions) (each of the formulations for

such variable price being herein referred to as, the “Variable Price”), the Company shall provide written notice thereof via electronic mail and overnight courier to the Holder on the date of such agreement and the issuance of such Common Stock, Convertible Securities or Options. From and after the date the Company enters into such agreement or issues any such Variable Price Securities (other than with respect to a Permitted ATM or pursuant to the Permitted Equity Lines or the 2026 Notes), the Holder shall have the right, but not the obligation, in its sole discretion to substitute the Variable Price for the Conversion Price upon conversion of this Note by designating in the Conversion Notice delivered upon any conversion of this Note that solely for purposes of such conversion the Holder is relying on the Variable Price rather than the Conversion Price then in effect. The Holder’s election to rely on a Variable Price for a particular conversion of this Note shall not obligate the Holder to rely on a Variable Price for any future conversion of this Note.

(4)Other Events. In the event that the Company (or any Subsidiary) shall take any action to which the provisions hereof are not strictly applicable, or, if applicable, would not operate to protect the Holder from dilution or if any event occurs of the type contemplated by the provisions of this Section 7 but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then the Company’s board of directors shall in good faith determine and implement an appropriate adjustment in the Reference Price so as to protect the rights of the Holder, provided that no such adjustment pursuant to this Section 7(d) will increase the Reference Price as otherwise determined pursuant to this Section 7, provided further that if the Holder does not accept such adjustments as appropriately protecting its interests hereunder against such dilution, then the Company’s board of directors and the Holder shall agree, in good faith, upon an independent investment bank of nationally recognized standing to make such appropriate adjustments, whose determination shall be final and binding absent manifest error and whose fees and expenses shall be borne by the Company.

(5)Calculations. All calculations under this Section 7 shall be made by rounding to the nearest cent or the nearest 1/100th of a share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company, and the disposition of any such shares shall be considered an issue or sale of Common Stock.

(6)Voluntary Adjustment by Company. Subject to the rules and regulations of the Nasdaq Stock Market, the Company may at any time during the term of this Note, with the prior written consent of the Required Holders (as defined in the Securities Purchase Agreement), reduce the then current Reference Price of each of the Notes to any amount and for any period of time deemed appropriate by the board of directors of the Company.

ARTICLE VIII.NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation (as defined in the Securities Purchase Agreement), Bylaws (as defined in the Securities Purchase Agreement) or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Note, and will at all times in good faith carry out all of the provisions of this Note and take all action as may be required to protect the rights of the Holder of this Note. Without limiting the generality of the foregoing or any other provision of this Note or the other Transaction Documents, the Company (a) shall not increase the par value of any shares of Common Stock receivable upon conversion of this Note above the

Conversion Price then in effect, and (b) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the conversion of this Note. Notwithstanding anything herein to the contrary, if after the sixty (60) calendar day anniversary of the Issuance Date, the Holder is not permitted to convert this Note in full for any reason (other than pursuant to restrictions set forth in Section 3(d) hereof), the Company shall use its best efforts to promptly remedy such failure, including, without limitation, obtaining such consents or approvals as necessary to permit such conversion into shares of Common Stock.

ARTICLE IX.RESERVATION OF AUTHORIZED SHARES.

(1)Reservation. So long as any Notes remain outstanding, the Company shall at all times reserve at least 150% of the number of shares of Common Stock as shall from time to time be necessary to effect the conversion, including without limitation, Alternate Conversions, of all of the Notes then outstanding (without regard to any limitations on conversions and assuming such Notes remain outstanding until the Maturity Date) at the lowest Conversion Price then in effect (the “Required Reserve Amount”). The Required Reserve Amount (including, without limitation, each increase in the number of shares so reserved) shall be allocated pro rata among the holders of the Notes based on the original principal amount of the Notes held by each holder on the Initial Closing Date or increase in the number of reserved shares, as the case may be (the “Authorized Share Allocation”). In the event that a holder shall sell or otherwise transfer any of such holder’s Notes, each transferee shall be allocated a pro rata portion of such holder’s Authorized Share Allocation. Any shares of Common Stock reserved and allocated to any Person which ceases to hold any Notes shall be allocated to the remaining holders of Notes, pro rata based on the principal amount of the Notes then held by such holders.

(2)Insufficient Authorized Shares. If, notwithstanding Section 9(a), and not in limitation thereof, at any time while any of the Notes remain outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon conversion of the Notes at least a number of shares of Common Stock equal to the Required Reserve Amount (an “Authorized Share Failure”), then the Company shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for the Notes then outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than ninety (90) days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its stockholders for the approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company shall provide each stockholder with a proxy statement and shall use its best efforts to solicit its stockholders’ approval of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal. Notwithstanding the foregoing, if at any such time of an Authorized Share Failure, the Company is able to obtain the written consent of a majority of the shares of its issued and outstanding shares of Common Stock to approve the increase in the number of authorized shares of Common Stock, the Company may satisfy this obligation by obtaining such consent and submitting for filing with the SEC an Information Statement on Schedule 14C. In the event that the Company is prohibited from issuing shares of Common Stock pursuant to the terms of this Note due to the failure by the Company to have sufficient shares of Common Stock available out of the authorized but unissued shares of Common Stock (such unavailable number of shares of Common Stock, the “Authorized Failure Shares”), in lieu of delivering such

Authorized Failure Shares to the Holder, the Company shall pay cash in exchange for the redemption of such portion of the Conversion Amount convertible into such Authorized Failure Shares at a price equal to the sum of (i) the product of (x) such number of Authorized Failure Shares and (y) the greatest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date the Holder delivers the applicable Conversion Notice with respect to such Authorized Failure Shares to the Company and ending on the date of such issuance and payment under this Section 9(a); and (ii) to the extent the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of Authorized Failure Shares, any brokerage commissions and other out-of-pocket expenses, if any, of the Holder incurred in connection therewith (but without any duplication of any Buy-In Payment Amount). Nothing contained in Section 9(a) or this Section 9(b) shall limit any obligations of the Company under any provision of the Securities Purchase Agreement.

ARTICLE X.SUBSEQUENT PLACEMENT OPTIONAL REDEMPTION

(1)General. At any time an Equity Conditions Failure exists at the time of consummation of a Subsequent Placement (as defined in the Securities Purchase Agreement)(in each case, other than with respect to Excluded Securities (as defined in the Securities Purchase Agreement)) (each, an “Eligible Subsequent Placement”), the Holder shall have the right, in its sole discretion, to require that the Company redeem (each, an “Subsequent Placement Optional Redemption”) all, or any portion, of the Conversion Amount under this Note not in excess of (together with any Subsequent Placement Optional Redemption Amount (as defined in the applicable other Note of the Holder) of any other Notes of the Holder) the Holder’s Holder Pro Rata Amount of 100% of the gross proceeds of such Eligible Subsequent Placement (the “Eligible Subsequent Placement Optional Redemption Amount”) by delivering written notice thereof (each, an “Subsequent Placement Optional Redemption Notice”) to the Company. To be effective, a Subsequent Placement Optional Redemption Notice, must be delivered to the Company no later than tenth (10th) Trading Day following the later of (x) the date of consummation of the related Eligible Subsequent Placement and (y) the date the Company delivers written notice to the Holder with respect to the related Eligible Subsequent Placement. Notwithstanding the foregoing, if the Holder is participating in an Eligible Subsequent Placement, upon the written request of the Holder, the Company shall apply all, or any part, as set forth in such written request, of any amounts that would otherwise be payable to the Holder in such Subsequent Placement Optional Redemption, on a dollar-for-dollar basis, against the purchase price of the securities to be purchased by the Holder in such Eligible Subsequent Placement.

(2)Mechanics. Each Subsequent Placement Optional Redemption Notice shall indicate that all, or such applicable portion, as set forth in the applicable Subsequent Placement Optional Redemption Notice, of the Eligible Subsequent Placement Optional Redemption Amount the Holder is electing to have redeemed (each, a “Subsequent Placement Optional Redemption Amount”) and the date of such Subsequent Placement Optional Redemption (each, a “Subsequent Placement Optional Redemption Date”), which shall be the later of (x) the fifth (5th) Business Day after the date of the applicable Subsequent Placement Optional Redemption Notice and (y) the date of the consummation of such Eligible Subsequent Placement. The portion of this Note subject to redemption pursuant to this Section 10 shall be redeemed by the Company in cash at a price equal to 100% of the Subsequent Placement Optional Redemption Amount (each, a “Subsequent Placement Optional Redemption Price”). Redemptions required by this Section 10 shall be made in accordance with the provisions of Section 11.

ARTICLE XI.REDEMPTIONS.

(1)Mechanics. The Company, or at the Company’s written direction and at the Company’s expense, the Trustee, shall deliver the applicable Event of Default Redemption Price to the Holder in cash within five (5) Business Days after the Company’s receipt of the Holder’s Event of Default Redemption Notice. If the Holder has submitted a Change of Control Redemption Notice in accordance with Section 5(b), the Company, or at the Company’s direction, the Trustee, shall deliver the applicable Change of Control Redemption Price to the Holder in cash concurrently with the consummation of such Change of Control if such notice is received prior to the consummation of such Change of Control and within five (5) Business Days after the Company’s receipt of such notice otherwise. The Company shall deliver the applicable Subsequent Placement Optional Redemption Price to the Holder in cash on the applicable Subsequent Placement Optional Redemption Date. Notwithstanding anything herein to the contrary, in connection with any redemption hereunder at a time the Holder is entitled to receive a cash payment under any of the other Transaction Documents, at the option of the Holder delivered in writing to the Company, the applicable Redemption Price hereunder shall be increased by the amount of such cash payment owed to the Holder under such other Transaction Document and, upon payment in full or conversion in accordance herewith, shall satisfy the Company’s payment obligation under such other Transaction Document. In the event of a redemption of less than all of the Conversion Amount of this Note, the Company shall promptly cause to be issued and delivered to the Holder a new Note (in accordance with Section 17(d)) representing the outstanding Principal which has not been redeemed. In the event that the Company does not pay the applicable Redemption Price to the Holder within the time period required, at any time thereafter and until the Company pays such unpaid Redemption Price in full, the Holder shall have the option, in lieu of redemption, to require the Company to promptly return to the Holder all or any portion of this Note representing the Conversion Amount that was submitted for redemption and for which the applicable Redemption Price (together with any Late Charges thereon) has not been paid. Upon the Company’s receipt of such notice, (x) the applicable Redemption Notice shall be null and void with respect to such Conversion Amount, (y) the Company shall immediately return this Note, or issue a new Note (in accordance with Section 17(d)), to the Holder, and in each case the principal amount of this Note or such new Note (as the case may be) shall be increased by an amount equal to the difference between (1) the applicable Redemption Price (as the case may be, and as adjusted pursuant to this Section 10, if applicable) minus (2) the Principal portion of the Conversion Amount submitted for redemption. The Holder’s delivery of a notice voiding a Redemption Notice and exercise of its rights following such notice shall not affect the Company’s obligations to make any payments of Late Charges which have accrued prior to the date of such notice with respect to the Conversion Amount subject to such notice.

(2)Redemption by Other Holders. Upon the Company’s receipt of notice from any of the holders of the Other Notes for redemption or repayment as a result of an event or occurrence substantially similar to the events or occurrences described in Section 4(b) or Section 5(b) (each, an “Other Redemption Notice”), the Company shall immediately, but no later than one (1) Business Day of its receipt thereof, forward to the Holder by electronic mail a copy of such notice. If the Company receives a Redemption Notice and one or more Other Redemption Notices, during the seven (7) Business Day period beginning on and including the date which is two (2) Business Days prior to the Company’s receipt of the Holder’s applicable Redemption Notice and ending on and including the date which is two (2) Business Days after the Company’s receipt of the Holder’s applicable Redemption Notice and the Company is unable to redeem all

principal, make-whole amount, interest and other amounts designated in such Redemption Notice and such Other Redemption Notices received during such seven (7) Business Day period, then the Company shall redeem a pro rata amount from each holder of the Notes (including the Holder) based on the principal amount of the Notes submitted for redemption pursuant to such Redemption Notice and such Other Redemption Notices received by the Company during such seven (7) Business Day period.

ARTICLE XII.VOTING RIGHTS. The Holder shall have no voting rights as the holder of this Note, except as required by law (including, without limitation, the Delaware General Corporation Law) and as expressly provided in this Note.

(3)Restricted Payments and Investments. The Company shall not, and the Company shall cause each of its Subsidiaries to not, directly or indirectly, redeem, defease, repurchase, repay or make any payments in respect of, by the payment of cash or cash equivalents (in whole or in part, whether by way of open market purchases, tender offers, private transactions or otherwise), all or any portion of any Debt (other than the Notes) whether by way of payment in respect of principal of (or premium, if any) or interest on, such Debt or make any Investment, as applicable, if at the time such payment with respect to such Debt and/or Investment, as applicable, is due or is otherwise made or, after giving effect to such payment, (i) an event constituting an Event of Default has occurred and is continuing or (ii) an event that with the passage of time and without being cured would constitute an Event of Default has occurred and is continuing; provided, however, that the Company may make any such payment if the Company concurrently makes the payment of the Event of Default Redemption Price on the outstanding portion of this Note.

(4)Change in Nature of Business.  The Company shall not, and the Company shall cause each of its Subsidiaries to not, directly or indirectly, engage in any material line of business substantially different from those material lines of business conducted by or publicly contemplated to be conducted by the Company and each of its Subsidiaries on the Subscription Date.

(7)Maintenance of Intellectual Property. The Company will, and will cause each of its Subsidiaries to, take all action necessary or advisable to maintain all of the Intellectual Property Rights (as defined in the Securities Purchase Agreement) of the Company and/or any of its Subsidiaries that are necessary or material to the conduct of its business in full force and effect.

The Company shall not, directly or indirectly, without the prior written consent of the holders of a majority in aggregate principal amount of the Notes then outstanding, (i) issue any Notes (other than as contemplated by the Securities Purchase Agreement and the Notes) or (ii) issue any other securities that would cause a breach or default under the Notes, unless the proceeds from the issuance of such securities are used to repay all amounts due on the Notes and the other Transaction Documents or (iii) issue any shares of Common Stock pursuant to any equity line or at-the-market offering during the three (3) Trading Day period immediately following any Conversion Date hereunder.

(11)Taxes. The Company and its Subsidiaries shall pay when due all taxes, fees or other charges of any nature whatsoever (together with any related interest or penalties) now or hereafter imposed or assessed against the Company and its Subsidiaries or their respective assets or upon their ownership, possession, use, operation or disposition thereof or upon their rents, receipts or earnings arising therefrom (except where the failure to pay would not, individually or in the aggregate, have a material effect on the Company or any of its Subsidiaries). The Company and its Subsidiaries shall file

on or before the due date therefor all personal property tax returns (except where the failure to file would not, individually or in the aggregate, have a material effect on the Company or any of its Subsidiaries). Notwithstanding the foregoing, the Company and its Subsidiaries may contest, in good faith and by appropriate proceedings, taxes for which they maintain adequate reserves therefor in accordance with GAAP.

(12)Independent Investigation. At the reasonable request of the Holder either (x) at any time when an Event of Default has occurred and is continuing, (y) upon the occurrence of an event that with the passage of time or giving of notice would constitute an Event of Default or (z) at any time the Holder reasonably believes an Event of Default may have occurred or be continuing, the Company shall hire an independent, reputable investment bank selected by the Company and approved by the Required Holders to investigate as to whether any breach of this Note has occurred (the “Independent Investigator”). If the Independent Investigator determines that such breach of this Note has occurred, the Independent Investigator shall notify the Company of such breach and the Company shall deliver written notice to each holder of a Note of such breach. In connection with such investigation, the Independent Investigator may, during normal business hours, inspect all contracts, books, records, personnel, offices and other facilities and properties of the Company and its Subsidiaries and, to the extent available to the Company after the Company uses reasonable efforts to obtain them, the records of its legal advisors and accountants (including the accountants’ work papers) and any books of account, records, reports and other papers not contractually required of the Company to be confidential or secret, or subject to attorney-client or other evidentiary privilege, and the Independent Investigator may make such copies and inspections thereof as the Independent Investigator may reasonably request. The Company shall furnish the Independent Investigator with such financial and operating data and other information with respect to the business and properties of the Company as the Independent Investigator may reasonably request. The Company shall permit the Independent Investigator to discuss the affairs, finances and accounts of the Company with, and to make proposals and furnish advice with respect thereto to, the Company’s officers, directors, key employees and independent public accountants or any of them (and by this provision the Company authorizes said accountants to discuss with such Independent Investigator the finances and affairs of the Company and any Subsidiaries), all at such reasonable times, upon reasonable notice, and as often as may be reasonably requested.

ARTICLE XIV.DISTRIBUTION OF ASSETS. In addition to any adjustments pursuant to Sections 6 or 7, if the Company shall declare or make any dividend or other distributions of its assets (or rights to acquire its assets) to any or all holders of shares of Common Stock, by way of return of capital or otherwise (including without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (the “Distributions”), then the Holder will be entitled to such Distributions as if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of this Note (without taking into account any limitations or restrictions on the convertibility of this Note and assuming for such purpose that the Note was converted at the Conversion Price as of the applicable record date) immediately prior to the date on which a record is taken for such Distribution or, if no such record is taken, the date as of which the record holders of Common Stock are to be determined for such Distributions (provided, however, that to the extent that the Holder’s right to participate in any such Distribution would result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Distribution to the extent of the Maximum Percentage (and shall not be entitled to beneficial ownership of such shares of Common Stock as a result of such Distribution (and beneficial ownership) to the extent of any such excess) and the portion of such Distribution

shall be held in abeyance for the benefit of the Holder until such time or times, if ever, as its right thereto would not result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, at which time or times the Holder shall be granted such Distribution (and any Distributions declared or made on such initial Distribution or on any subsequent Distribution held similarly in abeyance) to the same extent as if there had been no such limitation).

ARTICLE XV.AMENDING THE TERMS OF THIS NOTE. Except for Section 3(d), which may not be amended, modified or waived by the parties hereto, the prior written consent of the Required Holders shall be required for any amendment, modification or waiver to this Note. Any amendment, modification or waiver so approved shall be binding upon all existing and future holders of this Note and any Other Notes; provided, however, that no such change, waiver or, as applied to any of the Notes held by any particular holder of Notes, shall, without the written consent of that particular holder, (i) reduce the amount of Principal, reduce the amount of accrued and unpaid Interest or Make-Whole Amount, or extend the Maturity Date, of the Notes, (ii) disproportionally and adversely affect any rights under the Notes of any holder of Notes; or (iii) modify any of the provisions of, or impair the right of any holder of Notes under, this Section 15.

ARTICLE XVI.TRANSFER. This Note and any shares of Common Stock issued upon conversion of this Note may be offered, sold, assigned or transferred by the Holder without the consent of the Company, subject only to the provisions of Section 3(c)(iii) hereof and to the provisions of the Leak-Out Agreements (as defined in the Securities Purchase Agreement).

ARTICLE XVII.REISSUANCE OF THIS NOTE.

(1)Transfer. If this Note is to be transferred, the Holder shall surrender this Note to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Note (in accordance with Section 17(d)), registered as the Holder may request, representing the outstanding Principal being transferred by the Holder and, if less than the entire outstanding Principal is being transferred, a new Note (in accordance with Section 17(d)) to the Holder representing the outstanding Principal not being transferred. The Holder and any assignee, by acceptance of this Note, acknowledge and agree that, by reason of the provisions of Section 3(c)(iii) following conversion or redemption of any portion of this Note, the outstanding Principal represented by this Note may be less than the Principal stated on the face of this Note.

(2)Lost, Stolen or Mutilated Note. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Note (as to which a written certification and the indemnification contemplated below shall suffice as such evidence), and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary and reasonable form and, in the case of mutilation, upon surrender and cancellation of this Note, the Company shall execute and, following authentication of such new Note, deliver to the Holder a new Note (in accordance with Section 17(d)) representing the outstanding Principal.

(3)Note Exchangeable for Different Denominations. This Note is exchangeable, upon the surrender hereof by the Holder at the principal office of the Company, for a new Note or Notes (in accordance with Section 17(d) and in principal amounts of at least $1,000) representing in the aggregate the outstanding Principal of this Note, and each such new Note will represent such portion of such outstanding Principal as is designated by the Holder at the time of such surrender.

(4)Issuance of New Notes. Whenever the Company is required to issue a new Note pursuant to the terms of this Note, such new Note (i) shall be of like tenor with this Note, (ii) shall represent, as indicated on the face of such new Note, the Principal remaining outstanding (or in the case of a new Note being issued pursuant to Section 17(a) or Section 17(c), the Principal designated by the Holder which, when added to the principal represented by the other new Notes issued in connection with such issuance, does not exceed the Principal remaining outstanding under this Note immediately prior to such issuance of new Notes), (iii) shall have an issuance date, as indicated on the face of such new Note, which is the same as the Issuance Date of this Note, (iv) shall have the same rights and conditions as this Note, (v) shall be duly authenticated in accordance with the Indenture and (vi) shall represent accrued and unpaid Interest, Make-Whole Amount and Late Charges on the Principal, Make-Whole Amount and Interest of this Note, from the Issuance Date.

ARTICLE XVIII.REMEDIES, CHARACTERIZATIONS, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies provided in this Note shall be cumulative and in addition to all other remedies available under this Note and any of the other Transaction Documents at law or in equity (including a decree of specific performance and/or other injunctive relief). No failure on the part of the Holder to exercise, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof; nor shall any single or partial exercise by the Holder of any right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. In addition, the exercise of any right or remedy of the Holder at law or equity or under this Note or any of the documents shall not be deemed to be an election of Holder’s rights or remedies under such documents or at law or equity. The Company covenants to the Holder that there shall be no characterization concerning this instrument other than as expressly provided herein. Amounts set forth or provided for herein with respect to payments, conversion and the like (and the computation thereof) shall be the amounts to be received by the Holder and shall not, except as expressly provided herein, be subject to any other obligation of the Company (or the performance thereof). The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the Holder shall be entitled, in addition to all other available remedies, to specific performance and/or temporary, preliminary and permanent injunctive or other equitable relief from any court of competent jurisdiction in any such case without the necessity of proving actual damages and without posting a bond or other security. The Company shall provide all information and documentation to the Holder that is requested by the Holder to enable the Holder to confirm the Company’s compliance with the terms and conditions of this Note (including, without limitation, compliance with Section 7).

ARTICLE XIX.PAYMENT OF COLLECTION, ENFORCEMENT AND OTHER COSTS. If (a) this Note is placed in the hands of an attorney for collection or enforcement or is collected or enforced through any legal proceeding or the Holder otherwise takes action to collect amounts due under this Note and/or any other Transaction Document or to enforce the provisions of this Note and/or any other Transaction Document or (b) there occurs any bankruptcy, reorganization, receivership of the Company or other proceedings affecting Company creditors’ rights and involving a claim under this Note, then the Company shall pay the reasonable out-of-pocket costs incurred by the Holder for such collection, enforcement or action or in connection with such bankruptcy, reorganization, receivership or other proceeding, including, without limitation, reasonable attorneys’ fees and disbursements. The Company expressly acknowledges and agrees that no amounts due under this Note and/or any other

Transaction Document, as applicable, shall be affected, or limited, by the fact that the purchase price paid for this Note was less than the original Principal amount hereof.

ARTICLE XX.CONSTRUCTION; HEADINGS. This Note shall be deemed to be jointly drafted by the Company and the initial Holder and shall not be construed against any such Person as the drafter hereof. The headings of this Note are for convenience of reference and shall not form part of, or affect the interpretation of, this Note. Unless the context clearly indicates otherwise, each pronoun herein shall be deemed to include the masculine, feminine, neuter, singular and plural forms thereof. The terms “including,” “includes,” “include” and words of like import shall be construed broadly as if followed by the words “without limitation.” The terms “herein,” “hereunder,” “hereof” and words of like import refer to this entire Note instead of just the provision in which they are found. Unless expressly indicated otherwise, all section references are to sections of this Note. Terms used in this Note and not otherwise defined herein, but defined in the other Transaction Documents, shall have the meanings ascribed to such terms on the Initial Closing Date in such other Transaction Documents unless otherwise consented to in writing by the Holder.

ARTICLE XXI.FAILURE OR INDULGENCE NOT WAIVER. No failure or delay on the part of the Holder in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privilege. No waiver shall be effective unless it is in writing and signed by an authorized representative of the waiving party. Notwithstanding the foregoing, nothing contained in this Section 21 shall permit any waiver of any provision of Section 3(d).

ARTICLE XXII.DISPUTE RESOLUTION.

(1)Submission to Dispute Resolution.

(a)In the case of a dispute relating to a Closing Bid Price, a Closing Sale Price, a Conversion Price, Conversion Base Price, a VWAP or a fair market value or the arithmetic calculation of a Conversion Rate or the applicable Redemption Price (as the case may be) (including, without limitation, a dispute relating to the determination of any of the foregoing), the Company or the Holder (as the case may be) shall submit the dispute to the other party via electronic mail (A) if by the Company, within two (2) Business Days after the occurrence of the circumstances giving rise to such dispute or (B) if by the Holder at any time after the Holder learned of the circumstances giving rise to such dispute. If the Holder and the Company are unable to promptly resolve such dispute relating to such Closing Bid Price, such Closing Sale Price, such Conversion Price, such Conversion Base Price, such VWAP or such fair market value, or the arithmetic calculation of such Conversion Rate or such applicable Redemption Price (as the case may be), at any time after the second (2nd) Business Day following such initial notice by the Company or the Holder (as the case may be) of such dispute to the Company or the Holder (as the case may be), then the Holder may, at its sole option, select an independent, reputable investment bank to resolve such dispute.

(b)The Holder and the Company shall each deliver to such investment bank (A) a copy of the initial dispute submission so delivered in accordance with the first sentence of this Section 22 and (B) written documentation supporting its position with respect to such dispute, in each case, no later than 5:00 p.m. (New York time) by the fifth (5th) Business Day immediately following the date on

which the Holder selected such investment bank (the “Dispute Submission Deadline”) (the documents referred to in the immediately preceding clauses (A) and (B) are collectively referred to herein as the “Required Dispute Documentation”) (it being understood and agreed that if either the Holder or the Company fails to so deliver all of the Required Dispute Documentation by the Dispute Submission Deadline, then the party who fails to so submit all of the Required Dispute Documentation shall no longer be entitled to (and hereby waives its right to) deliver or submit any written documentation or other support to such investment bank with respect to such dispute and such investment bank shall resolve such dispute based solely on the Required Dispute Documentation that was delivered to such investment bank prior to the Dispute Submission Deadline). Unless otherwise agreed to in writing by both the Company and the Holder or otherwise requested by such investment bank, neither the Company nor the Holder shall be entitled to deliver or submit any written documentation or other support to such investment bank in connection with such dispute (other than the Required Dispute Documentation).

(c)The Company and the Holder shall use their reasonable best efforts to cause such investment bank to determine the resolution of such dispute and notify the Company and the Holder of such resolution no later than ten (10) Business Days immediately following the Dispute Submission Deadline. The fees and expenses of such investment bank shall be borne solely by the Company, and such investment bank’s resolution of such dispute shall be final and binding upon all parties absent manifest error.

(2)Miscellaneous. The Company expressly acknowledges and agrees that (i) this Section 22 constitutes an agreement to arbitrate between the Company and the Holder (and constitutes an arbitration agreement) under § 7501, et seq. of the New York Civil Practice Law and Rules (“CPLR”) and that the Holder is authorized to apply for an order to compel arbitration pursuant to CPLR § 7503(a) in order to compel compliance with this Section 22, (ii) the terms of this Note and each other applicable Transaction Document shall serve as the basis for the selected investment bank’s resolution of the applicable dispute, such investment bank shall be entitled (and is hereby expressly authorized) to make all findings, determinations and the like that such investment bank determines are required to be made by such investment bank in connection with its resolution of such dispute and in resolving such dispute such investment bank shall apply such findings, determinations and the like to the terms of this Note and any other applicable Transaction Documents, (iii) the Holder (and only the Holder), in its sole discretion, shall have the right to submit any dispute described in this Section 22 to any state or federal court sitting in The City of New York, Borough of Manhattan in lieu of utilizing the procedures set forth in this Section 22 and (iv) nothing in this Section 22 shall limit the Holder from obtaining any injunctive relief or other equitable remedies (including, without limitation, with respect to any matters described in this Section 22).

(3)Payments. Whenever any payment of cash is to be made by the Company to any Person pursuant to this Note, unless otherwise expressly set forth herein, such payment shall be made in lawful money of the United States of America by a certified check drawn on the account of the Company and sent via overnight courier service to such Person at such address as previously provided to the Company in writing (which address, in the case of each of the Buyers, shall initially be as set forth on the Schedule of Buyers attached to the Securities Purchase Agreement), provided that the Holder may elect to receive a payment of cash via wire transfer of immediately available funds by providing the Company with prior written notice setting out such request and the Holder’s wire transfer instructions. Whenever any amount expressed to be due by the terms of this Note is due on any day which is not a Business Day, the same shall instead be due on the next succeeding day which is a Business Day. Any amount of Principal or other amounts due under the Transaction Documents which is not paid when due (except to the extent such amount is simultaneously accruing Interest at the Default Rate hereunder) shall result in a late charge being incurred and payable by the Company in an amount equal to interest on such amount at the rate of fifteen percent (15%) per annum from the date such amount was due until the same is paid in full (“Late Charge”).

ARTICLE XXIV.CANCELLATION. After all Principal, Make-Whole Amount, accrued Interest, Late Charges and other amounts at any time owed on this Note or any other Transaction Documents have been paid in full, this Note shall automatically be deemed canceled, shall be surrendered to the Company for cancellation and shall not be reissued.

ARTICLE XXVI.GOVERNING LAW. This Note shall be construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Note shall be governed by, the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. Except as otherwise required by Section 22 above, the Company hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of

any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. Nothing contained herein (i) shall be deemed or operate to preclude the Holder from bringing suit or taking other legal action against the Company in any other jurisdiction to collect on the Company’s obligations to the Holder, or to enforce a judgment or other court ruling in favor of the Holder or (ii) shall limit, or shall be deemed or construed to limit, any provision of Section 22. THE COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS NOTE OR ANY TRANSACTION CONTEMPLATED HEREBY.

ARTICLE XXVII.JUDGMENT CURRENCY.

(1)If for the purpose of obtaining or enforcing judgment against the Company in any court in any jurisdiction it becomes necessary to convert into any other currency (such other currency being hereinafter in this Section 27 referred to as the “Judgment Currency”) an amount due in U.S. dollars under this Note, the conversion shall be made at the Exchange Rate prevailing on the Trading Day immediately preceding:

(a)the date actual payment of the amount due, in the case of any proceeding in the courts of New York or in the courts of any other jurisdiction that will give effect to such conversion being made on such date: or

(b)the date on which the foreign court determines, in the case of any proceeding in the courts of any other jurisdiction (the date as of which such conversion is made pursuant to this Section 27(a)(ii) being hereinafter referred to as the “Judgment Conversion Date”).

(2)If in the case of any proceeding in the court of any jurisdiction referred to in Section 27(a)(ii) above, there is a change in the Exchange Rate prevailing between the Judgment Conversion Date and the date of actual payment of the amount due, the applicable party shall pay such adjusted amount as may be necessary to ensure that the amount paid in the Judgment Currency, when converted at the Exchange Rate prevailing on the date of payment, will produce the amount of US dollars which could have been purchased with the amount of Judgment Currency stipulated in the judgment or judicial order at the Exchange Rate prevailing on the Judgment Conversion Date.

(3)Any amount due from the Company under this provision shall be due as a separate debt and shall not be affected by judgment being obtained for any other amounts due under or in respect of this Note.

ARTICLE XXVIII.TAX MATTERS.

(1)Any and all payments by the Company hereunder, including any amounts (or shares of Common Stock) received on a conversion or redemption of the Note and any amounts on account of interest or deemed interest, shall be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, unless the Company is

required to withhold or deduct any amounts for, or on account of any applicable law (each, a “Withheld Amount”). If the Company shall be required to deduct any Withheld Amount from or in respect of any sum payable hereunder to the Holder, (i) the sum payable shall be increased by the amount by which the sum payable would otherwise have to be increased (the “tax make-whole amount”) to ensure that after making all required deductions (including deductions applicable to the tax make-whole amount) the Holder would receive an amount equal to the sum it would have received had no such deductions been made, (ii) the Company shall make such deductions and (iii) the Company shall pay the full amount withheld or deducted to the relevant governmental authority within the time required.

(a)In addition, the Company agrees to pay to the relevant governmental authority in accordance with applicable law any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from any payment made hereunder or in connection with the execution, delivery, registration or performance of, or otherwise with respect to, this Note (“Other Taxes”).

(b)The Company shall deliver to the Holder official receipts, if any, in respect of any taxes payable hereunder promptly after payment of such taxes or other evidence of payment reasonably acceptable to the Holder.

(c)If the Company fails to pay any amounts in accordance with this Section 28, the Company shall indemnify the Holder within ten (10) calendar days after written demand therefor, for the full amount of any such taxes, plus any related interest or penalties, that are paid by the Holder to the relevant governmental authority as a result of such failure.

(d)The obligations of the Company under this Section 28(a) shall survive the termination of this Note and the payment of the Note and all other amounts payable hereunder.

(2)Each Holder and beneficial owner of this Note, by the acceptance of this Note or acquisition of any beneficial interest therein, and the Company each mutually covenant and agree, to treat this Note as indebtedness for all purposes and will not take any action contrary to such characterization, including filing any tax returns or financial statements inconsistent therewith.

(3)Each Holder and beneficial owner of a Note, by the acceptance of such Note or acquisition of any beneficial interest therein, covenants and agrees, for the benefit of the Company, to the extent it is legally able to do so, to provide to the Company and its paying agent (if any) such properly completed and executed reasonable documentation, information or certification (including, but not limited to, Internal Revenue Service Forms W-8BEN, W-8BEN-E, W-8IMY, W-8ECI, W-8EXP and W-9, (or any successor forms) and portfolio interest certificates) as (1) would reduce or eliminate withholding taxes imposed on any amount payable by the Company (and its paying agent, if any) and/or (2) may be helpful (as reasonably determined by the Company or its paying agent) for the Company (and its paying agent, if any) to satisfy its obligations relating to FATCA, withholding (including backup withholding) and information reporting under the Code and any other applicable law.

(4)To the extent this Note is subject to Section 871(m) of the Code, for purposes of Section 871(m) of the Code and the regulations thereunder, the Common

Stock is not expected to have a dividend during the life of the Note and therefore the estimate of the dividend amount for such purposes is zero.

ARTICLE XXIX.SEVERABILITY. If any provision of this Note is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Note so long as this Note as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).

ARTICLE XXX.MAXIMUM PAYMENTS. Without limiting Section 9(d) of the Securities Purchase Agreement, nothing contained herein shall be deemed to establish or require the payment of a rate of interest or other charges in excess of the maximum permitted by applicable law. In the event that the rate of interest required to be paid or other charges hereunder exceed the maximum permitted by such law, any payments in excess of such maximum shall be credited against amounts owed by the Company to the Holder and thus refunded to the Company.
