CONVERTIBLE NOTE 
  

			
	Issuance Date: [—] 2014	  	Original Principal Amount: U.S. $[—]

 FOR VALUE RECEIVED, Ascent Solar Technologies, Inc., a Delaware corporation (the
“Company”), hereby promises to pay to the order of [BUYER] or its registered assigns (“Holder”) the amount set forth above as the Original Principal Amount (as reduced pursuant to the terms hereof pursuant to
redemption, conversion or otherwise, the “Principal”) when due, whether upon the Maturity Date, on any Installment Date with respect to the Installment Amount due on such Installment Date (each as defined below), or upon
acceleration, redemption or otherwise (in each case in accordance with the terms hereof) and to pay interest (“Interest”) on any outstanding Principal at the applicable Interest Rate (as defined below) from the date set forth above
as the Issuance Date (the “Issuance Date”) until the same becomes due and payable, whether upon the Maturity Date, on any Installment Date with respect to the Installment Amount due on such Installment Date, or upon acceleration,
conversion, redemption or otherwise (in each case in accordance with the terms hereof). This Senior Secured Convertible Note (including all 

 
Senior Secured Convertible Notes issued in exchange, transfer or replacement hereof, this “Note”) is one of an issue of Senior Secured Convertible Notes issued pursuant to the
Securities Purchase Agreement, dated as of November 14, 2014 (the “Subscription Date”), by and among the Company and the investors (the “Buyers”) referred to therein, as amended from time to time (collectively,
the “Notes”, and such other Senior Secured Convertible Notes, the “Other Notes”). Certain capitalized terms used herein are defined in Section 33. 

1. PAYMENTS OF PRINCIPAL. On each Installment Date, the Company shall pay to the Holder an amount equal to the Installment Amount due
on such Installment Date in accordance with Section 8. On the Maturity Date, the Company shall pay to the Holder an amount in cash (excluding any amounts paid in shares of Common Stock on the Maturity Date in accordance with Section 8)
representing all outstanding Principal, accrued and unpaid Interest and accrued and unpaid Late Charges (as defined in Section 26(c)) on such Principal and Interest. Other than as specifically permitted by this Note, the Company may not prepay
any portion of the outstanding Principal, accrued and unpaid Interest or accrued and unpaid Late Charges on Principal and Interest, if any. 

2. INTEREST; INTEREST RATE. 

(a) Interest on this Note shall commence accruing on the Issuance Date and shall be computed on the basis of a 360-day year and
twelve 30-day months and shall be payable in arrears on each Interest Date and shall compound each calendar month and shall be payable in accordance with the terms of this Note. Interest shall be paid (i) on each Interest Date occurring on an
Installment Date in accordance with Section 8 as part of the applicable Installment Amount due on the applicable Installment Date and (ii) with respect to each other Interest Date, on such Interest Date in cash. 

(b) 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 12 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 shall automatically be increased to fifteen percent (15.0%) per annum. In the event that such Event of Default is subsequently cured,
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. 

3. CONVERSION OF NOTES. At any time after the Issuance Date, 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. 

(a) Conversion Right. Subject to the provisions of Section 3(d), at any time or times on or after the Issuance
Date, the Holder shall be entitled to convert any portion of 

  
 2 

 
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. 
 (b)
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”). 
 (i) “Conversion Amount” means the sum of (x) portion of the
Principal to be converted, redeemed or otherwise with respect to which this determination is being made, and (y) all accrued and unpaid Interest with respect to such portion of the Principal amount and accrued and unpaid Late Charges with
respect to such portion of such Principal and such Interest, if any. 
 (ii) “Conversion Price” means, as of
any Conversion Date or other date of determination, $2.25, subject to adjustment as provided herein. 
 (c) Mechanics of
Conversion. 
 (i) Optional Conversion. To convert any Conversion Amount into shares of Common Stock on any date
(a “Conversion Date”), the Holder shall deliver (whether via facsimile, 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 (the “Conversion Notice”) to the Company. If required by Section 3(c)(iii), within three (3) 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 20(b)). On or
before the first (1st) Trading Day following the date of receipt of a Conversion Notice, the Company shall transmit by facsimile or electronic mail an acknowledgment of confirmation, in the form attached hereto as Exhibit II, of receipt
of such Conversion Notice to the Holder and the Company’s transfer agent (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 third (3rd) Trading Day following the date of receipt of 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) (the “Share Delivery Deadline”), the Company shall (1)

  
 3 

 
provided that the Transfer Agent is participating in The Depository Trust Company’s (“DTC”) Fast Automated Securities Transfer Program, credit such aggregate number of
shares of Common Stock 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 (2) if the Transfer Agent is not participating in the DTC
Fast Automated Securities Transfer Program, 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 the number of shares of
Common Stock to which the Holder shall be entitled. 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 practicable and in no event later than three (3) 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 20(d)) representing the outstanding Principal 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. In the event of a partial conversion of this Note pursuant hereto, the Principal amount converted shall be deducted from the Installment Amount(s) relating to the Installment Date(s) as
set forth in the applicable Conversion Notice. Notwithstanding anything to the contrary contained in this Note or the Registration Rights Agreement, the Company shall cause the Transfer Agent to deliver unlegended shares of Common Stock to the
Holder (or its designee) in connection with any sale of Registrable Securities (as defined in the Registration Rights Agreement) with respect to which the Holder has entered into a contract for sale, and delivered a copy of the prospectus included
as part of the particular Registration Statement (as defined in the Registration Rights Agreement) to the extent applicable, after the effective date of such Registration Statement and prior to the Holder’s receipt of the notice of a Grace
Period (as defined in the Registration Rights Agreement) and for which the Holder has not yet settled. 
 (ii)
Company’s Failure to Timely Convert. If the Company shall fail, for any reason or for no reason, on or prior to the applicable Share Delivery Deadline, to issue to the Holder a certificate for the number of shares of Common Stock to
which the Holder is entitled and register such shares of Common Stock on the Company’s share register or to credit the Holder’s or its designee’s balance account with DTC for such number of shares of Common Stock to which the Holder
is entitled upon the Holder’s conversion of any Conversion Amount (as the case may be) (a “Conversion Failure”), and if on or after such Share Delivery Deadline 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 all or any portion of the number of shares of Common Stock, or a sale of a number of shares of Common Stock equal to all or any portion of the number of shares of Common
Stock, issuable upon such conversion that the Holder so anticipated receiving from the Company, then, in addition to all other remedies available to the Holder, the Company shall, within three (3) 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 

  
 4 

 
Holder’s total purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares of Common Stock so purchased (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 or credit the Holder’s balance account 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 Holder’s balance account 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). 

(iii) Registration; Book-Entry. The Company 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 and Restricted Principal held by such holders held by such holders (the “Registered Notes”). 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 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 Company 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 20, 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 3, 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 and the Company shall maintain records showing the Principal, Interest and Late Charges
converted and/or paid (as the case may be) or Restricted Principal becoming unrestricted and the dates of such conversions, Control Account Release (as defined below) and/or payments (as the case may be) or shall use such

  
 5 

 
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, Interest and Late Charges converted and/or paid (as the case may be) or Restricted Principal becoming unrestricted and the dates of such conversions, Control Account Release 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. 

(iv) 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 25. 
 (d) Limitations on
Conversions. 
 (i) Beneficial Ownership Limitation. 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, including the Preferred Shares and the 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 

  
 6 

 
Percentage, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (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 

  
 7 

 
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. 
 (ii) 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 (taken together with the issuance of all other shares of Common Stock upon
conversion of the Other Notes, the Preferred Shares or exercise of the Warrants or otherwise pursuant to the terms of the Notes, the Warrants or the Certificate of Designations) would exceed the aggregate number of shares of Common Stock which the
Company may issue upon exercise or conversion (as the case may be) of the Warrants, the Preferred Shares, the Notes and or otherwise pursuant to the respective terms thereof 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, 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 outside 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, any Preferred Shares, or any of the Warrants or otherwise pursuant to the terms of the Notes, the Warrants or the Certificate of Designations, 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 Closing Date divided by (2) the aggregate original principal
amount of all Notes issued to the Buyers pursuant to the Securities Purchase Agreement on the 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, Preferred Shares and Warrants, 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 and Preferred Shares and such holder’s exercise in full of such Warrants
shall be allocated, to the respective Exchange Cap Allocations of the remaining holders of Notes, Preferred Shares and related Warrants on a pro rata basis in proportion to the shares of Common Stock underlying the Notes, the Preferred Shares and
related Warrants then held by each such holder of Notes, Preferred Shares and related Warrants. In the event that the Company is prohibited from issuing any shares of Common Stock pursuant to this Section 3(d)(ii) (the “Exchange Cap
Shares”), the Company shall pay cash to the Holder in exchange for the redemption of such portion 

  
 8 

 
of the Conversion Amount convertible into such Exchange Cap Shares at a price (the “Exchange Cap Share Cancellation Amount”) equal to the sum of (i) the product of
(x) such number of Exchange Cap Shares and (y) the Closing Sale Price on the Trading Day immediately preceding the date the Holder delivers the applicable Conversion Notice with respect to such Exchange Cap Shares to the Company 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 Exchange Cap Shares, any brokerage commissions and other out-of-pocket expenses,
if any, of the Holder incurred in connection therewith. 
 (e) Right of Alternate Conversion. 

(i) General. At any time the Holder may, at the Holder’s option, by delivery of a Conversion Notice to the Company
(the date of any such Conversion Notice, each an “Alternate Conversion Date”), convert all, or any part of, the Conversion Amount (such portion of the Conversion Amount to be converted pursuant to this Section 3(e)(i), the
“Alternate Conversion Amount”) into shares of Common Stock at the Alternate Conversion Price with (x) any such conversion with respect to such Alternate Conversion Date occurring prior to or after any Event of Default
Redemption Right Period (as defined below), being referred to herein as an “Alternate Optional Conversion” and (y) any such conversion with respect to such Alternate Conversion Date occurring during any Event of Default
Redemption Right Period, being referred to herein as an “Alternate Default Conversion” (with each Alternate Default Conversion and Alternate Optional Conversion collectively being referred to herein as an “Alternate
Conversion”); provided, that, the Holder shall not be permitted to effect an Alternate Optional Conversion hereunder with respect to any given date of determination to the extent the sum of (x) the aggregate Alternate Conversion Amount
of each Alternate Optional Conversion consummated pursuant to this Note prior to the such date of determination and (y) the aggregate Alternate Conversion Amount (as defined in the Certificate of Designations) of each Alternate Optional
Conversion (as defined in the Certificate of Designations) consummated pursuant to the Preferred Shares of the Holder prior to such date of determination, collectively, exceeds the Holder Pro Rata Amount of $28 million. 

(ii) Mechanics of Alternate Conversion. On any Alternate Conversion Date, the Holder may voluntarily convert any
Alternate Conversion Amount pursuant to Section 3(c) (with “Alternate Conversion Price” replacing “Conversion Price” for all purposes hereunder with respect to such Alternate Conversion and, solely with respect to the
calculation of the number of shares of Common Stock issuable upon conversion of any Conversion Amount in an Alternate Default Conversion, 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 to use the Alternate
Conversion Price for such conversion. Notwithstanding anything to the contrary in this Section 3(e), but subject to 

  
 9 

 
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). 
 (f)
Mandatory Conversion. 
 (i) General. If at any time (i) the Closing Sale Price of the Common Stock listed
on the Principal Market exceeds the Conversion Price by 200% for fifteen (15) consecutive Trading Days (each, a “Mandatory Conversion Measuring Period”), and (ii) no Equity Conditions Failure then exists, the Company shall
have the right to require the Holder to convert all, or any part, of the Conversion Amount of this Note, as designated in the Mandatory Conversion Notice (as defined below) into fully paid, validly issued and nonassessable shares of Common Stock in
accordance with Section 3(c) hereof at the Conversion Rate as of the Mandatory Conversion Date (as defined below) (a “Mandatory Conversion”). The Company may exercise its right to require conversion under this Section 3(f)
by delivering within two Trading Days following the end of such Mandatory Conversion Measuring Period a written notice thereof by facsimile and overnight courier to all, but not less than all, of the holders of Notes and the Transfer Agent (the
“Mandatory Conversion Notice” and the date all of the holders received such notice by facsimile is referred to as the “Mandatory Conversion Notice Date”). The Mandatory Conversion Notice shall be irrevocable. The
Mandatory Conversion Notice shall state (i) the Trading Day selected for the Mandatory Conversion in accordance with this Section 3(f), which Trading Day shall be no less than three (3) Trading Days and no more than fifteen
(15) Trading Days following the Mandatory Conversion Notice Date (the “Mandatory Conversion Date”), (ii) the aggregate Conversion Amount, of the Notes subject to mandatory conversion from the Holder and all of the holders
of the Notes pursuant to this Section 3(f) (and analogous provisions under the Other Notes), (iii) the number of shares of Common Stock to be issued to such Holder on the Mandatory Conversion Date and (iv) that there has been no
Equity Conditions Failure. Notwithstanding the foregoing, the Company may effect only one (1) Mandatory Conversion during any twenty (20) consecutive Trading Days. Notwithstanding anything herein to the contrary, (i) if the Closing
Sale Price of the Common Stock listed on the Principal Market fails to exceed the Conversion Price by 200% for each Trading Day commencing on the Mandatory Conversion Notice Date and ending and including the Trading Day immediately prior to the
applicable Mandatory Conversion Date (a “Mandatory Conversion Price Failure”) or an Equity Conditions Failure occurs at any time prior to the Mandatory Conversion Date, (A) the Company shall provide the Holder a subsequent
notice to that effect and (B) unless the Holder waives the applicable Equity Conditions Failure and/or Mandatory Conversion Price Failure, as applicable, the Mandatory Conversion shall be cancelled and the applicable Mandatory Conversion Notice
shall be null and void and (ii) at any time prior to the date the Mandatory Conversion Price is paid, in full, the Mandatory Conversion Amount may be converted, in whole or in part, by the Holders into

  
 10 

 
shares of Common Stock pursuant to Section 3. Notwithstanding the foregoing, any Conversion Amount subject to a Mandatory Conversion may be converted by the Holder hereunder prior to the
applicable Mandatory Conversion Date and such aggregate Conversion Amount converted hereunder on or after the Mandatory Conversion Notice Date and prior to such Mandatory Conversion Date shall reduce the Mandatory Conversion Amount to be converted
on such Mandatory Conversion Date. For the avoidance of doubt, the Company shall have no right to effect a Mandatory Conversion if any Event of Default has occurred and continuing, but any Event of Default shall have no effect upon the Holder’s
right to convert this Note in its discretion. 
 (ii) Pro Rata Conversion Requirement. If the Company elects to cause
a Mandatory Conversion of this Note pursuant to Section 3(f), then it must simultaneously take the same action with respect to all of the Other Notes. 

4. RIGHTS UPON EVENT OF DEFAULT. 

(a) Event of Default. Each of the following events shall constitute an “Event of Default” and each of
the events in clauses (ix), (x) and (xi) shall constitute a “Bankruptcy Event of Default”: 
 (i)
the failure of the applicable Registration Statement (as defined in the Registration Rights Agreement) to be filed with the SEC on or prior to the date that is five (5) days after the applicable Filing Deadline (as defined in the Registration
Rights Agreement) or the failure of the applicable Registration Statement to be declared effective by the SEC on or prior to the date that is ten (10) Trading Days after the applicable Effectiveness Deadline (as defined in the Registration
Rights Agreement); 
 (ii) while the applicable Registration Statement is required to be maintained effective pursuant to the
terms of the Registration Rights Agreement, the effectiveness of the applicable Registration Statement lapses for any reason (including, without limitation, the issuance of a stop order) or such Registration Statement (or the prospectus contained
therein) is unavailable to any holder of Registrable Securities (as defined in the Registration Rights Agreement) for sale of all of such holder’s Registrable Securities in accordance with the terms of the Registration Rights Agreement, and
such lapse or unavailability continues for a period of five (5) consecutive Trading Days or for more than an aggregate of ten (10) Trading Days in any 365-day period (excluding days during an Allowable Grace Period (as defined in the
Registration Rights Agreement)); 
 (iii) 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; 
 (iv) the
Company’s notice, written or oral, to any holder of the Notes, Preferred Shares or Warrants, including, without limitation, by way of public 

  
 11 

 
announcement or through any of its agents, at any time, of its intention not to comply, as required, with a request for conversion of any Notes into shares of Common Stock that is requested in
accordance with the provisions of the Notes, other than pursuant to Section 3(d), or a request for exercise of any Warrants for Warrant Shares in accordance with the provisions of the Warrants or a request for conversion of any Preferred Shares

 14 

 
limitation, the Security Documents and the Guaranties) shall at any time for any reason (other than pursuant to the express terms thereof) cease to be valid and binding on or enforceable against
the parties thereto, or the validity or enforceability thereof shall be contested by any party thereto, or a proceeding shall be commenced by the Company or any Subsidiary or any governmental authority having jurisdiction over any of them, seeking
to establish the invalidity or unenforceability thereof, or the Company or any Subsidiary shall deny in writing that it has any liability or obligation purported to be created under any Transaction Document (including, without limitation, the

curtailment of revenue producing activities at any facility of the Company or any Subsidiary, if any such event or circumstance could have a Material Adverse Effect; or 

(xxii) any Event of Default (as defined in the Other Notes) occurs with respect to any Other Notes. 

(b) Notice of an Event of Default; Redemption Right. Upon 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 facsimile or electronic mail and overnight courier (with next day delivery specified) (an “Event of Default Notice”) to
the Holder. 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 

  
 15 

 
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, 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 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 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 12. 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 4(b), 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.
In the event of a partial redemption of this Note pursuant hereto, the Principal amount redeemed shall be deducted from the Installment Amount(s) relating to the applicable Installment Date(s) as set forth in the Event of Default Redemption Notice.
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. 
 (c) 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, accrued and unpaid Interest and accrued and unpaid Late Charges on such Principal and Interest, multiplied by (ii) the Redemption Premium, in addition to any and all other amounts due hereunder,

  
 16 

 
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. 
 5. RIGHTS UPON FUNDAMENTAL
TRANSACTION. 
 (a) Assumption. The Company shall not enter into or be party to a Fundamental Transaction unless
(i) the Successor Entity 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) pursuant to written agreements in form and
substance satisfactory to the Holder and approved by the Holder prior to such Fundamental Transaction, including agreements to deliver to each holder of Notes in exchange for such Notes a security of the Successor Entity evidenced by a written
instrument substantially similar in form and substance to the Notes, 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 and security to the Notes, and satisfactory to the Holder and (ii) the Successor Entity (including its Parent Entity) is a publicly traded corporation whose common stock
is quoted on or listed for trading on an Eligible Market. Upon the occurrence of any Fundamental Transaction, the Successor Entity 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), 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 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 17, 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 (including its Parent Entity) 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. 

  
 17 

 (b) Notice of a Change of Control; Redemption Right. No sooner than twenty
(20) Trading Days nor later than ten (10) Trading Days prior to the 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 facsimile or electronic mail and overnight courier to the Holder (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 the later of twenty (20) Trading Days
after (A) consummation of such Change of Control or (B) the date of receipt of such Change of Control Notice, 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, 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 12 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 

  
 18 

 
a partial redemption of this Note pursuant hereto, the Principal amount redeemed shall be deducted from the Installment Amount(s) relating to the applicable Installment Date(s) as set forth in
the Change of Control Redemption Notice. 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. 
 6.
RIGHTS UPON ISSUANCE OF PURCHASE RIGHTS AND OTHER CORPORATE EVENTS. 
 (a) Purchase Rights. In addition to any
adjustments pursuant to Section 7 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) 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 such extent (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 such extent) and such Purchase Right to
such extent shall be held in abeyance for 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 to be held similarly in abeyance) to the same extent as if there had been no such limitation). 

(b) 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 

  
 19 

 
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 satisfactory to the Holder.
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. 

7. RIGHTS UPON ISSUANCE OF OTHER SECURITIES. 

(a) Adjustment of Conversion Price upon Issuance of Common Stock. If and whenever on or after the Subscription Date the
Company issues or sells, or in accordance with this Section 7(a) is deemed to have issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the account of the Company, but
excluding any Excluded Securities issued or sold or deemed to have been issued or sold) for a consideration per share (the “New Issuance Price”) less than a price equal to the Conversion Price in effect immediately prior to such
issue or sale or deemed issuance or sale (such Conversion Price then in effect is referred to herein as the “Applicable Price”) (the foregoing a “Dilutive Issuance”), then, immediately after such Dilutive Issuance,
the Conversion Price then in effect shall be reduced to the New Issuance Price. For all purposes of the foregoing (including, without limitation, determining the adjusted Conversion Price and the New Issuance Price under this Section 7(a)), the
following shall be applicable: 
 (i) Issuance of Options. If the Company in any manner grants or sells any Options
and the lowest price per share for which one share of Common Stock is at any time issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option or
otherwise pursuant to the terms thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such
price per share. For purposes of this Section 7(a)(i), the “lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities
issuable upon exercise of any such Option or otherwise pursuant to the terms thereof” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to
any one share of Common Stock upon the granting or sale of such Option, upon exercise of such Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option or otherwise pursuant to the terms
thereof and (y) the lowest exercise price set forth in such Option for which one share of Common Stock is issuable upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable upon
exercise of any such Option or otherwise pursuant to the terms thereof, minus (2) the sum of all amounts paid or 

  
 20 

 
payable to the holder of such Option (or any other Person) upon the granting or sale of such Option, upon exercise of such Option and upon conversion, exercise or exchange of any Convertible
Security issuable upon exercise of such Option or otherwise pursuant to the terms thereof plus the value of any other consideration received or receivable by, or benefit conferred on, the holder of such Option (or any other Person). Except as
contemplated below, no further adjustment of the Conversion Price shall be made upon the actual issuance of such share of Common Stock or of such Convertible Securities upon the exercise of such Options or otherwise pursuant to the terms thereof or
upon the actual issuance of such share of Common Stock upon conversion, exercise or exchange of such Convertible Securities. 

(ii) Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the
lowest price per share for which one share of Common Stock is at any time issuable upon the conversion, exercise or exchange thereof or otherwise pursuant to the terms thereof is less than the Applicable Price, then such share of Common Stock shall
be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section 7(a)(ii), the “lowest price per share
for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof or otherwise pursuant to the terms thereof” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if
any) received or receivable by the Company with respect to one share of Common Stock upon the issuance or sale of the Convertible Security and upon conversion, exercise or exchange of such Convertible Security or otherwise pursuant to the terms
thereof and (y) the lowest conversion price set forth in such Convertible Security for which one share of Common Stock is issuable upon conversion, exercise or exchange thereof or otherwise pursuant to the terms thereof minus (2) the sum
of all amounts paid or payable to the holder of such Convertible Security (or any other Person) upon the issuance or sale of such Convertible Security plus the value of any other consideration received or receivable by, or benefit conferred on, the
holder of such Convertible Security (or any other Person). Except as contemplated below, no further adjustment of the Conversion Price shall be made upon the actual issuance of such share of Common Stock upon conversion, exercise or exchange of such
Convertible Securities or otherwise pursuant to the terms thereof, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of the Conversion Price has been or is to be made pursuant to
other provisions of this Section 7(a), except as contemplated below, no further adjustment of the Conversion Price shall be made by reason of such issue or sale. 

(iii) Change in Option Price or Rate of Conversion. If the purchase or exercise price provided for in any Options, the
additional consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exercisable or exchangeable for shares of Common Stock
increases or decreases at any time, the Conversion Price in effect at the time of such increase or decrease shall 

  
 21 

 
be adjusted to the Conversion Price which would have been in effect at such time had such Options or Convertible Securities provided for such increased or decreased purchase price, additional
consideration or increased or decreased conversion rate (as the case may be) at the time initially granted, issued or sold. For purposes of this Section 7(a)(iii), if the terms of any Option or Convertible Security that was outstanding as of
the Subscription Date are increased or decreased in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof
shall be deemed to have been issued as of the date of such increase or decrease. No adjustment pursuant to this Section 7(a) shall be made if such adjustment would result in an increase of the Conversion Price then in effect. 

(iv) Calculation of Consideration Received. If any Option and/or Convertible Security and/or Adjustment Right is issued
in connection with the issuance or sale or deemed issuance or sale of any other securities of the Company (as determined by the Holder, the “Primary Security”, and such Option and/or Convertible Security and/or Adjustment Right, the
“Secondary Securities”), together comprising one integrated transaction (or one or more transactions if such issuances or sales or deemed issuances or sales of securities of the Company either (A) have at least one investor or
purchaser in common, (B) are consummated in reasonable proximity to each other and/or (C) are consummated under the same plan of financing), the consideration per share of Common Stock with respect to such Primary Security shall be deemed
to be equal to the difference of (x) the lowest price per share for which one share of Common Stock was issued in such integrated transaction (or was deemed to be issued pursuant to Section 7(a)(i) or 7(a)(ii) above, as applicable) solely
with respect to such Primary Security, minus (y) with respect to such Secondary Securities, the sum of (A) the Black Scholes Consideration Value of each such Option, if any, (B) the fair market value (as determined by the Holder in
good faith) or the Black Scholes Consideration Value, as applicable, of such Adjustment Right, if any, and (C) the fair market value (as determined by the Holder) of such Convertible Security, if any, in each case, as determined on a per share
basis in accordance with this Section 7(a)(iv). If any shares of Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor (for the purpose of
determining the consideration paid for such Common Stock, Option or Convertible Security, but not for the purpose of the calculation of the Black Scholes Consideration Value) will be deemed to be the net amount of consideration received by the
Company therefor. If any shares of Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash (for the purpose of determining the consideration paid for such Common Stock, Option or Convertible Security,
but not for the purpose of the calculation of the Black Scholes Consideration Value), the amount of such consideration received by the Company will be the fair value of such consideration, except where such consideration consists of publicly traded
securities, in which case the amount of consideration received by the Company for such securities will be the average VWAP of such security for the five (5) Trading Day period immediately preceding the date of receipt. If any shares of Common
Stock, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any 

  
 22 

 
merger in which the Company is the surviving entity (for the purpose of determining the consideration paid for such Common Stock, Option or Convertible Security, but not for the purpose of the
calculation of the Black Scholes Consideration Value), the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such shares of Common
Stock, Options or Convertible Securities (as the case may be). The fair value of any consideration other than cash or publicly traded securities will be determined jointly by the Company and the Holder. If such parties are unable to reach agreement
within ten (10) days after the occurrence of an event requiring valuation (the “Valuation Event”), the fair value of such consideration will be determined within five (5) Trading Days after the tenth (10th) day following such Valuation Event by an independent, reputable appraiser jointly selected by the Company and the Holder. The determination of such appraiser shall be final and binding upon
all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Company. 
 (v) Record
Date. If the Company takes a record of the holders of shares of Common Stock for the purpose of entitling them (A) to receive a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or
(B) to subscribe for or purchase shares of Common Stock, Options or Convertible Securities, then such record date will be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the
declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase (as the case may be). 

(b) Adjustment of Conversion Price upon Subdivision or Combination of Common Stock. Without limiting any provision of
Section 5 or Section 7(a), 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 Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. Without limiting any provision of Section 5 or Section 7(a), 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 Conversion 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 Conversion Price is calculated hereunder, then the calculation of such Conversion Price shall be adjusted appropriately to reflect such
event. 
 (c) Holder’s Right of Adjusted Conversion Price. In addition to and not in limitation of the other
provisions of this Section 7 or Section 4(n) of the Securities Purchase Agreement, other than with respect to any Excluded Preferred Securities, 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 (any such securities, “Variable Price 

  
 23 

 
Securities”) that are issuable pursuant to such agreement or convertible into or exchangeable or exercisable for shares of Common Stock pursuant to such Options or Convertible
Securities, as applicable, 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 facsimile or electronic mail and overnight courier to the Holder on the date of such agreement and/or the issuance of such shares of Common Stock, Convertible Securities or Options, as applicable. From and after the date the
Company enters into such agreement or issues any such Variable Price Securities, 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. 

(d) Stock Combination Event Adjustments. If at any time and from time to time on or after the Subscription Date there
occurs any stock split, stock dividend, stock combination recapitalization or other similar transaction involving the Common Stock (each, a “Stock Combination Event”, and such date thereof, the “Stock Combination Event
Date”) and the Event Market Price is less than the Conversion Price then in effect (after giving effect to the adjustment in Section 7(b) above), then on the sixteenth
(16th) Trading Day immediately following such Stock Combination Event Date, the Conversion Price then in effect on such sixteenth
(16th) Trading Day (after giving effect to the adjustment in Section 7(b) above) shall be reduced (but in no event increased) to the Event Market Price. 

(e) 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 Conversion Price so as to protect the rights of the Holder, provided that no such adjustment pursuant to this Section 7(e) will increase the Conversion 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. 

(f) Calculations. All calculations under this Section 7 shall be made by

  
 24 

 
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. 

(g) Voluntary Adjustment by Company. The Company may at any time during the term of this Note, with the prior written
consent of the Required Holders, reduce the then current Conversion Price to any amount and for any period of time deemed appropriate by the board of directors of the Company. 

8. INSTALLMENT CONVERSION OR REDEMPTION. 

(a) General. On each applicable Installment Date, provided there has been no Equity Conditions Failure, the Company
shall pay to the Holder of this Note the applicable Installment Amount due on such date by converting such Installment Amount in accordance with this Section 8 (a “Installment Conversion”); provided, however, that
the Company may, at its option following notice to the Holder as set forth below, pay the Installment Amount by redeeming such Installment Amount in cash (a “Installment Redemption”) or by any combination of an Installment
Conversion and an Installment Redemption so long as all of the outstanding applicable Installment Amount due on any Installment Date shall be converted and/or redeemed by the Company on the applicable Installment Date, subject to the provisions of
this Section 8. On the date which is the twenty-first (21st) Trading Day prior to each Installment Date (each, an “Installment Notice Due Date”), the Company shall
deliver written notice (each, a “Installment Notice” and the date all of the holders receive such notice is referred to as to the “Installment Notice Date”), to each holder of Notes and such Installment Notice shall
(i) either (A) confirm that the applicable Installment Amount of such holder’s Note shall be converted in whole pursuant to an Installment Conversion or (B) (1) state that the Company elects to redeem for cash, or is
required to redeem for cash in accordance with the provisions of the Notes, in whole or in part, the applicable Installment Amount pursuant to an Installment Redemption and (2) specify the portion of such Installment Amount which the Company
elects or is required to redeem pursuant to an Installment Redemption (such amount to be redeemed in cash, the “Installment Redemption Amount”) and the portion of the applicable Installment Amount, if any, with respect to which the
Company will, and is permitted to, effect an Installment Conversion (such amount of the applicable Installment Amount so specified to be so converted pursuant to this Section 8 is referred to herein as the “Installment Conversion
Amount”), which amounts when added together, must at least equal the entire applicable Installment Amount and (ii) if the applicable Installment Amount is to be paid, in whole or in part, pursuant to an Installment Conversion, certify
that there is not then an Equity Conditions Failure as of the applicable Installment Notice Date. Each Installment Notice shall be irrevocable. If the Company does not timely deliver an Installment Notice in accordance with this Section 8 with
respect to a particular Installment Date, then the Company shall be deemed to have delivered an irrevocable Installment Notice confirming an Installment Conversion of the entire Installment Amount payable on such Installment Date and shall be deemed
to have certified that there is not then an Equity Conditions Failure in connection with such Installment Conversion. No later than three (3) Trading Days (or 

  
 25 

 
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 Installment Notice Due Date of such
shares of Common Stock issuable pursuant to the applicable Installment Notice) after delivery or deemed delivery (as applicable) of the applicable Installment Notice setting forth an Installment Conversion Amount, the Company shall deliver to the
Holder’s account with DTC such number of shares of Common Stock (the “Pre-Installment Conversion Shares”) equal to the quotient of (x) such Installment Conversion Amount divided by (y) the Pre-Installment Conversion
Price, and as to which the Holder shall be the owner thereof as of such time of delivery or deemed delivery (as the case may be) of such Installment Notice. Except as expressly provided in this Section 8(a), the Company shall convert and/or
redeem the applicable Installment Amount of this Note pursuant to this Section 8 and the corresponding Installment Amounts of the Other Notes pursuant to the corresponding provisions of the Other Notes in the same ratio of the applicable
Installment Amount being converted and/or redeemed hereunder. The applicable Installment Conversion Amount (whether set forth in the applicable Installment Notice or by operation of this Section 8) shall be converted in accordance with
Section 8(b) and the applicable Installment Redemption Amount shall be redeemed in accordance with Section 8(c). 

(b) Mechanics of Installment Conversion. Subject to Section 3(d), if the Company delivers an Installment Notice or
is deemed to have delivered an Installment Notice certifying that such Installment Amount is being paid, in whole or in part, in an Installment Conversion in accordance with Section 8(a), then the remainder of this Section 8(b) shall
apply. The applicable Installment Conversion Amount, if any, shall be converted on the applicable Installment Date at the applicable Installment Conversion Price and the Company shall, on such Installment Date, deliver to the Holder’s account
with DTC such shares of Common Stock issued upon such conversion (subject to the reduction contemplated by the immediately following sentence and, if applicable, the penultimate sentence of this Section 8(b)), provided that the Equity
Conditions are then satisfied (or waived in writing by the Holder) on such Installment Date and an Installment Conversion is not otherwise prohibited under any other provision of this Note. The number of shares of Common Stock to be delivered upon
such Installment Conversion shall be reduced by the number of any Pre-Installment Conversion Shares delivered in connection with such Installment Date. If an Event of Default occurs during any applicable Equity Conditions Measuring Period, then, at
the option of the Holder designated in writing to the Company, either (i) the Holder shall return to the Company all, or any part, of such Pre-Installment Conversion Shares delivered in connection with the applicable Installment Date or
(ii) the Conversion Amount used to calculate the Event of Default Redemption Price shall be reduced by the product of (x) the Installment Conversion Amount applicable to such Installment Date (as adjusted downward proportionally with
respect to any Pre-Installment Conversion Shares returned to the Company pursuant to clause (i) above) multiplied by (y) the Conversion Share Ratio. If the Company confirmed (or is deemed to have confirmed by operation of
Section 8(a)) the conversion of the applicable Installment Conversion Amount, in whole or in part, and there was no Equity Conditions Failure as of the applicable Installment Notice Date (or is deemed to have certified that the Equity
Conditions in connection with any such conversion have been satisfied by operation of Section 8(a)) but an Equity 

  
 26 

 
Conditions Failure occurred between the applicable Installment Notice Date and any time through the applicable Installment Date (the “Interim Installment Period”), the Company
shall provide the Holder a subsequent notice to that effect. If there is an Equity Conditions Failure (which is not waived in writing by the Holder) during such Interim Installment Period or an Installment Conversion is not otherwise permitted under
any other provision of this Note, then, at the option of the Holder designated in writing to the Company, the Holder may require the Company to do any one or more of the following: (i) the Company shall redeem all or any part designated by the
Holder of the unconverted Installment Conversion Amount (such designated amount is referred to as the “Designated Redemption Amount”) and the Company shall pay to the Holder within three (3) days of such Installment Date, by
wire transfer of immediately available funds, an amount in cash equal to 125% of such Designated Redemption Amount, and/or (ii) the Installment Conversion shall be null and void with respect to all or any part designated by the Holder of the
unconverted Installment Conversion Amount and the Holder shall be entitled to all the rights of a holder of this Note with respect to such designated part of the Installment Conversion Amount; provided, however, the Conversion Price for such
designated part of such unconverted Installment Conversion Amount shall thereafter be adjusted to equal the lesser of (A) the Installment Conversion Price as in effect on the date on which the Holder voided the Installment Conversion and
(B) the Installment Conversion Price that would be in effect on the date on which the Holder delivers a Conversion Notice relating thereto as if such date was an Installment Date. In addition, if any of the Equity Conditions are not satisfied
(or waived in writing by the Holder) on such Installment Date or an Installment Conversion is not otherwise permitted under any other provision of this Note, then, at the Holder’s option, either (I) the Holder shall return any
Pre-Installment Conversion Shares delivered in connection with the applicable Installment Date or (II) the applicable Designated Redemption Amount shall be reduced by the product of (X) the Installment Conversion Amount applicable to such
Installment Date multiplied by (Y) the Conversion Share Ratio. If the Company fails to redeem any Designated Redemption Amount by the third (3rd) day following the applicable Installment
Date by payment of such amount by such date, then the Holder shall have the rights set forth in Section 12(a) as if the Company failed to pay the applicable Installment Redemption Price (as defined below) and all other rights under this Note
(including, without limitation, such failure constituting an Event of Default described in Section 4(a)(vi)). Notwithstanding anything to the contrary in this Section 8(b), but subject to 3(d), until the Company delivers Common Stock
representing the Installment Conversion Amount to the Holder, the Installment Conversion Amount may be converted by the Holder into Common Stock pursuant to Section 3. In the event that the Holder elects to convert the Installment Conversion
Amount prior to the applicable Installment Date as set forth in the immediately preceding sentence, the Installment Conversion Amount so converted shall be deducted from the Installment Amount(s) relating to the applicable Installment Date(s) as set
forth in the applicable Conversion Notice. Notwithstanding anything herein to the contrary, if, with respect to an Installment Date, the number of Pre-Installment Conversion Shares delivered to the Holder exceeds the number of Post-Installment
Conversion Shares with respect to such Installment Date, then the number of shares of Common Stock equal to such excess shall constitute a credit, at the option of the Holder, against the number of shares of Common Stock to be issued to such Holder

  
 27 

 
either (x) in any conversion of this Note pursuant to Section 3(c)(i) as selected by the Holder or (y) on the Maturity Date, or, if earlier, the last Installment Date. The Company
shall pay any and all taxes that may be payable with respect to the issuance and delivery of any shares of Common Stock in any Installment Conversion hereunder. 

(c) Mechanics of Installment Redemption. If the Company elects or is required to effect an Installment Redemption, in
whole or in part, in accordance with Section 8(a), then the Installment Redemption Amount, if any, shall be redeemed by the Company in cash on the applicable Installment Date by wire transfer to the Holder of immediately available funds in an
amount equal to the applicable Installment Redemption Amount (the “Installment Redemption Price”). If the Company fails to redeem such Installment Redemption Amount on such Installment Date by payment of the Installment Redemption
Price, then, at the option of the Holder designated in writing to the Company (any such designation shall be a “Conversion Notice” for purposes of this Note), the Holder may require the Company to convert all or any part of the
Installment Redemption Amount at the Installment Conversion Price (determined as of the date of such designation as if such date were an Installment Date). Conversions required by this Section 8(c) shall be made in accordance with the
provisions of Section 3(c). Notwithstanding anything to the contrary in this Section 8(c), but subject to Section 3(d), until the Installment Redemption Price (together with any Late Charges thereon) is paid in full, the Installment
Redemption Amount (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 the Holder elects to convert all or any portion of the Installment Redemption
Amount prior to the applicable Installment Date as set forth in the immediately preceding sentence, the Installment Redemption Amount so converted shall be deducted from the Installment Amounts relating to the applicable Installment Date(s) as set
forth in the applicable Conversion Notice. Redemptions required by this Section 8(c) shall be made in accordance with the provisions of Section 12. 

(d) Deferred Installment Amount. Notwithstanding any provision of this Section 8(d) to the contrary, the Holder
may, at its option and in its sole discretion, deliver a written notice to the Company no later than the Trading Day immediately prior to the applicable Installment Date electing to have the payment of all or any portion of an Installment Amount
payable on such Installment Date deferred (such amount deferred, the “Deferral Amount”, and such deferral, each a “Deferral”) until any subsequent Installment Date selected by the Holder, in its sole discretion, in
which case, the Deferral Amount shall be added to, and become part of, such subsequent Installment Amount and such Deferral Amount shall continue to accrue Interest hereunder. Any notice delivered by the Holder pursuant to this Section 8(d)
shall set forth (i) the Deferral Amount and (ii) the date that such Deferral Amount shall now be payable. 
 (e)
Acceleration of Installment Amounts. Notwithstanding any provision of this Section 8 to the contrary, but subject to Section 3(d), if the Company delivers an Installment Notice and confirms, or is deemed to have delivered and
confirmed, in whole or in part, an Installment Conversion in accordance with Section 8(a) (each such applicable Installment Date, a “Current Installment Date”), during the period commencing on the Installment Notice Due Date
immediately prior to such applicable 

  
 28 

 
Current Installment Date and ending on the Trading Day immediately prior to the next Installment Date (each, an “Installment Period”), the Holder may elect, at its option and in
its sole discretion, at one or more times in such Installment Period, either (x) if such election is made prior to third (3rd) Trading Day immediately prior to such Current Installment Date (each, a “Pre-Delivery Acceleration
Expiration Date”), to increase the Installment Conversion Amount (and related Installment Amount) with respect to such Current Installment Date in which case, such Acceleration Amount(s) (as defined below) shall be added to, and become part
of, the Installment Amount as such Installment Amount may have been increased pursuant to the terms hereof, payable on such applicable Installment Date by including such Acceleration Amount(s) in the Installment Amount for the applicable Installment
Date and shall be payable in Common Stock by including such Acceleration Amount(s) in the Installment Conversion Amount for the applicable Installment Date and (y) if such election is made on or after the Pre-Delivery Acceleration Expiration
Date, to convert other Installment Amounts as of such election date (each, an “Acceleration”, and each such amount of acceleration or conversion, as applicable, an “Acceleration Amount”, and each such election date,
an “Acceleration Date”), in whole or in part, at the Installment Conversion Price of such Current Installment Date (with “Installment Conversion Price” replacing “Conversion Price” and the “Acceleration
Date” replacing “Conversion Date” for all purposes hereunder with respect to such Acceleration) in accordance with the conversion procedures set forth in Section 3 hereunder, mutatis mutandis. Any such notice delivered by
the Holder (each, an “Acceleration Notice”) shall set forth (i) the Acceleration Amount(s), (ii) the applicable Current Installment Date and (iii) the date that such Acceleration Amount(s) should have been paid if not
for the Holder’s right to accelerate such Installment Amount(s) pursuant to this Section 8(e). To the extent more than one Installment Period exists as of an Acceleration Date, the Holder shall also elect in such Acceleration Notice which
Pre-Installment Conversion Price or Installment Conversion Price, as applicable, that shall apply with respect to such Acceleration. The Company shall deliver Pre-Installment Conversion Shares to the Holder with respect to any Acceleration occurring
prior to the Pre-Delivery Acceleration Expiration Date related to the Current Installment Date attributable to such Acceleration as soon as commercially practicable after the applicable Acceleration Date, but no later than the second (2nd) Trading Day after such Acceleration Date. Subject to Section 3(d), until the Company delivers shares of Common Stock representing the applicable Acceleration Amount to the Holder, such
Acceleration Amount may be converted by the Holder into shares of Common Stock pursuant to Section 3(c) without regard to this Section 8(e). Notwithstanding anything to the contrary in this Section 8(e), (with respect to each period
commencing on an Installment Notice Due Date (the “Current Installment Notice Due Date”) and ending on the Trading Day immediately prior to the next Installment Notice Due Date (each, an “Acceleration Measuring
Period”), the Holder may not elect to effect an Acceleration (the “Current Acceleration”, and such date of determination, the “Current Acceleration Determination Date”) during such Acceleration Measuring
Period if the sum of (x) the Installment Conversion Amount with respect to the Installment Date related to such Current Acceleration (as adjusted for such Current Acceleration and any other Accelerations and Deferrals during such Acceleration
Measuring Period)and (y) the Installment Conversion Amount with respect to the Installment Date related to such 

  
 29 

 
Current Acceleration (as adjusted for such Current Acceleration and any other Accelerations and Deferrals during such Acceleration Measuring Period), collectively, exceeds five (5) times the
Installment Amount with respect to the Installment Date related to such Current Acceleration (without regard to any Accelerations or Deferrals with respect to the Installment Date related to such Current Acceleration). 

9. REDEMPTIONS AT THE COMPANY’S ELECTION. 

(a) Company Optional Redemption. At any time after the later of (x) thirty (30) calendar days after the
Applicable Date (as defined in the Securities Purchase Agreement) and (y) the date no Equity Conditions Failure exists, the Company shall have the right to redeem all, but not less than all, of the Conversion Amount then remaining under this
Note (the “Company Optional Redemption Amount”) on the Company Optional Redemption Date (each as defined below) (a “Company Optional Redemption”). The portion of this Note subject to redemption pursuant to this
Section 9(a) shall be redeemed by the Company in cash at a price (the “Company Optional Redemption Price”) equal to 120% of the greater of (i) the Conversion Amount being redeemed as of the Company Optional Redemption Date
and (ii) the product of (1) the Conversion Rate with respect to the Conversion Amount being redeemed as of the Company Optional Redemption Date 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 Company Optional Redemption Notice Date and ending on the Trading Day immediately prior to the date the Company makes the entire payment required to be made under this
Section 9(a). The Company may exercise its right to require redemption under this Section 9(a) by delivering a written notice thereof by facsimile or electronic mail and overnight courier to all, but not less than all, of the holders of
Notes (the “Company Optional Redemption Notice” and the date all of the holders of Notes received such notice is referred to as the “Company Optional Redemption Notice Date”). The Company may deliver only one
Company Optional Redemption Notice hereunder and such Company Optional Redemption Notice shall be irrevocable. The Company Optional Redemption Notice shall (x) state the date on which the Company Optional Redemption shall occur (the
“Company Optional Redemption Date”) which date shall not be less than ninety (90) Trading Days nor more than one hundred (100) Trading Days following the Company Optional Redemption Notice Date, (y) certify that there
has been no Equity Conditions Failure and (z) state the aggregate Conversion Amount of the Notes which is being redeemed in such Company Optional Redemption from the Holder and all of the other holders of the Notes pursuant to this
Section 9(a) (and analogous provisions under the Other Notes) on the Company Optional Redemption Date. Notwithstanding anything herein to the contrary, (i) if no Equity Conditions Failure has occurred as of the Company Optional Redemption
Notice Date but an Equity Conditions Failure occurs at any time prior to the Company Optional Redemption 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 Company Optional Redemption shall be cancelled and the applicable Company Optional Redemption Notice shall be null and void and (ii) at any time prior to the date the Company Optional Redemption Price is paid, in full,
the Company Optional Redemption Amount may be converted, in whole or in part, by the Holder into shares of Common 

  
 30 

 
Stock pursuant to Section 3. All Conversion Amounts converted by the Holder after the Company Optional Redemption Notice Date shall reduce the Company Optional Redemption Amount of this Note
required to be redeemed on the Company Optional Redemption Date. Redemptions made pursuant to this Section 9(a) shall be made in accordance with Section 12. In the event of the Company’s redemption of any portion of this Note under
this Section 9, 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 9 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. For the avoidance of doubt, the Company shall have no right to effect a Company Optional Redemption if any Event of Default has occurred and continuing, but any Event of Default shall have no effect upon the Holder’s right to convert
this Note in its discretion. 
 (b) Pro Rata Redemption Requirement. If the Company elects to cause a Company Optional
Redemption of this Note pursuant to Section 9(a), then it must simultaneously take the same action with respect to all of the Other Notes. 

10. 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, (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, and (c) shall, so long as any of the Notes are outstanding, take all action necessary to reserve and keep available out of its authorized and unissued shares of Common Stock, solely for
the purpose of effecting the conversion of the Notes, the maximum number of shares of Common Stock as shall from time to time be necessary to effect the conversion of the Notes then outstanding (without regard to any limitations on conversion
contained herein). Notwithstanding anything herein to the contrary, if after the seventy-five (75) 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)(i) hereof), the Company shall use its best efforts to promptly remedy such failure, including, without limitation, obtaining such consents or approvals as necessary to effect such conversion into shares of
Common Stock. 
 11. RESERVATION OF AUTHORIZED SHARES. 

(a) Reservation. So long as any Notes remain outstanding, the Company shall at all times reserve at least 200% of the
number of shares of Common Stock as shall from 

  
 31 

 
time to time be necessary to effect the conversion, including without limitation, Installment Conversions, Alternate Conversions and Accelerations, of all of the Notes then outstanding (without
regard to any limitations on conversions and assuming such Notes remain outstanding until the Maturity Date) (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 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. 

(b) Insufficient Authorized Shares. If, notwithstanding Section 11(a), and not in limitation thereof, 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 seventy five (75) 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. In the event that the Company is prohibited from issuing shares of Common Stock upon any conversion 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 11(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. Nothing contained in Section 11(a) or this Section 11(b) shall limit any obligations of the
Company under any provision of the Securities Purchase Agreement. 

  
 32 

 12. REDEMPTIONS. 

(a) Mechanics. The Company 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 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 Installment Redemption Price to the Holder in cash on the applicable Installment Date. The Company shall deliver the applicable Company Optional
Redemption Price to the Holder in cash on the applicable Company Optional 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 20(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 20(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 12, if applicable) minus (2) the Principal portion of the Conversion Amount submitted for redemption and (z) the Conversion Price of this Note or such new Notes (as the case may be)
shall be automatically adjusted with respect to each conversion effected thereafter by the Holder to the lowest of (A) the Conversion Price as in effect on the date on which the applicable Redemption Notice is voided, (B) 80% of the lowest
Closing Bid Price of the Common Stock during the period beginning on and including the date on which the applicable Redemption Notice is delivered to the Company and ending on and including the date on which the applicable Redemption Notice is
voided and (C) 80% of the quotient of (I) the sum of the five (5) lowest VWAPs of the Common Stock during the twenty (20) consecutive Trading Day period ending and 

  
 33 

 
including the Trading Day immediately preceding the applicable Conversion Date divided by (II) five (5) (it being understood and agreed that all such determinations shall be appropriately
adjusted for any stock dividend, stock split, stock combination or other similar transaction during such period). 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.

immediately, but no later than one (1) Business Day of its receipt thereof, forward to the Holder by facsimile or electronic mail a copy of such notice. If the Company receives a Redemption Notice and one or more Other Redemption Notices,

is three (3) Business Days after the Company’s receipt of the Holder’s applicable Redemption Notice and the Company is unable to redeem all principal, 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. 

13. VOTING RIGHTS. The Holder shall have no voting rights as the holder of this Note, except as required by law (including, without

defined below). Each such Controlled Account Agreement shall provide, among other things, that (A) the Controlled Account 

  
 38 

 
Bank will comply with any and all instructions originated by the Collateral Agent directing the disposition of the funds in the Controlled Accounts without further consent by the Company or any
such Subsidiaries, (B) the Controlled Account Bank waives, subordinates or agrees not to exercise any rights of setoff or recoupment or any other claim against the applicable Controlled Account other than for payment of its service fees and

directions or orders of any form with respect to the Operating Accounts other than instructions, directions or orders originated by Collateral Agent. The Collateral Agent shall not issue an Activation Instruction with respect to the Operating
Accounts unless an Event of Default has occurred and is continuing at the time such Activation Instruction is issued. 
 (ii)
Additional Controlled Account Agreements. If at any time on or after the Closing Date, the average daily balance of any Account of the Company or any of its Subsidiaries that is not subject to a Controlled Account Agreement, in form and

month in which the Closing Date occurs), the Company shall either (x) within twenty-one (21) calendar days following the last day of such calendar month, deliver to the Collateral Agent a Controlled Account Agreement, in form and substance

(iii) Maximum Free Cash Amount. Notwithstanding anything to the contrary contained in Section 14(q)(ii) above, and

 39 

 (iv) Holder Master Restricted Account. 

(1) General. The Company shall establish and maintain a bank account for each holder of Notes (collectively, including
the Holder Master Restricted Account, the “Master Restricted Accounts”) at a Controlled Account Bank, which Master Restricted Account applicable to a holder of Notes shall be subject to a Controlled Account Agreement in form and
substance reasonably acceptable to such holder of Notes. On the Issuance Date, the Company shall have directed the initial Buyers to deposit an aggregate of $30.5 million of the Purchase Price (as defined in the Securities Purchase Agreement) into
Master Restricted Accounts. 
 (2) Control Account Release. Upon the occurrence of any Control Account Release Event,
the Holder shall, as soon as commercially practicable, but in no event later than two (2) Trading Days thereafter, cause the applicable Control Account Release Amount to be released from the Holder Master Restricted Account and deposited into
an bank account specified in writing by the Company on or prior to such date (each a “Control Account Release”); provided, that if the Company fails to select a bank account in a writing delivered to the Holder on or prior to such
second Trading Day, the Holder shall effect such Control Account Release as soon as commercially practicable after receipt of such bank account election from the Company. 

(3) Grant of Security Interest. The Company hereby grants and pledges to the Holder a continuing security interest in
any cash or other assets, from time to time, in the Holder Master Restricted Account attributable to the Restricted Principal hereunder (the “Collateral”) to secure prompt repayment of any and all amounts outstanding hereunder from
time to time and to secure prompt performance by the Company of each of its covenants and duties under the Transaction Documents (as defined in the Securities Purchase). Such security interest constitutes a valid, first priority security interest in
the presently existing Collateral, and will constitute a valid, first priority security interest in later-acquired Collateral. Notwithstanding any filings undertaken related to Holder’s rights under the Delaware Uniform Commercial Code, the
Holder’s Lien (as defined in the Notes) on the Collateral shall remain in effect for so long as any Restricted Principal remains outstanding. Notwithstanding the foregoing, upon any Control Account Release, but solely with respect to such
portion of the Restricted Principal hereunder subject to such Control Account Release (each, a “Control Account Release Amount”), the Holder hereby automatically releases any lien hereunder on such Control Account Release
Amount. 
 (4) Cash Payment Obligations. Notwithstanding anything herein to the contrary, at the option of the
Holder, the Holder may satisfy all, or any part, of any redemption or other cash payment obligation of the Company hereunder and/or pursuant to any other Transaction Document (as defined in the Securities Purchase Agreement) (each, a “Cash
Payment Obligation”) from the Collateral in the Holder Master Restricted Account, including, without limitation, 

  
 40 

 
in connection with any Event of Default, Change of Control, Company Installment Redemption or payment due at the Maturity Date. In connection with any Cash Payment Obligation hereunder, the
Company hereby irrevocably consents to the Holder’s delivery of an instruction letter to the Controlled Account Bank to release Collateral from the Holder Master Restricted Account in an amount not to exceed such Cash Payment Obligation to the
Holder. Notwithstanding the foregoing, in the absence of any such election by the Holder, the Company shall remain obligated to pay such Cash Payment Obligation to the Holder without regard to any Collateral in the Holder Master Restricted
Account. Upon the occurrence of any event which could reasonably be expected to result in a Cash Payment Obligation, the Holder may, at the Holder’s option, withdraw any Collateral in the Holder Master Restricted Account; provided that
(x) such withdrawn amount shall not exceed such amount which the Holder reasonably believes would be necessary to satisfy such Cash Payment Obligation, and (y) such withdrawal shall not constitute the delivery of a Redemption Notice
hereunder or payment hereunder unless the Holder specifies in writing to the Company that the Holder has applied such Collateral in satisfaction of such Cash Payment Obligation. 

(5) Breach of Controlled Account Agreement. If the Controlled Account Bank breaches any covenant or other term or
condition of any Account Control Agreement or otherwise fails to promptly comply with the instructions of the Holder in connection with the Collateral, the Holder may, at its option, withdraw the Collateral from the Controlled Account Bank and hold
such Collateral until such time as (x) the Company and the Holder have agreed upon a replacement Controlled Account Bank and (y) a Controlled Account Agreement with respect to such Collateral and a new account shall have been duly executed
by the Company, the Holder and the replacement Controlled Account Bank. Notwithstanding anything herein to the contrary, if the Company or any of its Subsidiaries receives any of the Collateral in breach of any Account Control Agreement (or receives
notice from any holder of Notes that an amount was wired to the Company from a Master Restricted Account attributable to such holder of Notes without the proper authorization of such holder of Notes), the Company shall promptly cause such amounts to
be returned to such applicable Master Restricted Account. 
 (r) Independent Investigation. At the 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 Holder 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 

  
 41 

 
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. 
 15. SECURITY. This Note and the Other Notes are secured to the extent and in the manner set forth in the Transaction
Documents (including, without limitation, the Security Agreement, the other Security Documents and the Guaranties). 
 16. DISTRIBUTION
OF ASSETS. In addition to any adjustments pursuant to Section 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) 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 such extent (and shall not be entitled to beneficial ownership of such shares of Common Stock as a result of such Distribution (and beneficial ownership) to
such extent) and the portion of such Distribution shall be held in abeyance for the Holder until such time or times as its right thereto would not result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, at which time
or times, if any, the Holder shall be granted such rights (and any rights under this Section 17 on such initial rights or on any subsequent such rights to be held similarly in abeyance) to the same extent as if there had been no such
limitation). 
 17. AMENDING THE TERMS OF THIS NOTE. The prior written consent of the holders of Notes representing at least
sixty-five (65%) of the aggregate principal amount of the Notes then outstanding shall be required for any change, waiver or amendment to this Note. Any 

  
 42 

 
change, waiver or amendment 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 extend the Maturity Date, of the
Notes, (ii) disproportionally and adversely affect any rights under the Notes of any holder of Notes (except that a holder of Notes that does not have any of its Notes secured by cash amounts in a Master Control Account will not be deemed to be
disproportionally and adversely effected by any change, waiver or amendment to any other holder’s Notes or consideration granted to any other holder of Notes in connection with any change, waiver or amendment related to any provision relating
to any Master Restricted Account); or (iii) modify any of the provisions of, or impair the right of any holder of Notes under, this Section 17. 

18. TRANSFER. This Note and any shares of Common Stock issued upon conversion of this Note may be offered, sold, assigned or

ASCENT SOLAR TECHNOLOGIES, INC. 

WARRANT TO PURCHASE COMMON STOCK 

Warrant No.:     
 Date of Issuance:
[            ], 2014 (“Issuance Date”) 
 Ascent Solar
Technologies, Inc., a Delaware corporation (the “Company”), hereby certifies that, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, [BUYER], the registered holder hereof or its
permitted assigns (the “Holder”), is entitled, subject to the terms set forth below, to purchase from the Company, at the Exercise Price (as defined below) then in effect, upon exercise of this Warrant to Purchase Common Stock
(including any Warrants to Purchase Common Stock issued in exchange, transfer or replacement hereof, the “Warrant”), at any time or times on or after the six month anniversary of the Issuance Date (the “Initial
Exercisability Date”), but not after 11:59 p.m., New York time, on the Expiration Date (as defined below), 7,777,778 (subject to adjustment as provided herein) fully paid and non-assessable shares of Common Stock (as defined below) (the
“Warrant Shares”, and such number of Warrant Shares, the “Warrant Number”). Except as otherwise defined herein, capitalized terms in this Warrant shall have the meanings set forth in Section 17. This Warrant is one of
the Warrants to Purchase Common Stock (the “SPA Warrants”) issued pursuant to Section 1 of that certain Securities Purchase Agreement, dated as of November 14, 2014 (the “Subscription Date”), by and among
the Company and the investors (the “Buyers”) referred to therein, as amended from time to time (the “Securities Purchase Agreement”). 

 1. EXERCISE OF WARRANT. 

(a) Mechanics of Exercise. Subject to the terms and conditions hereof (including, without limitation, the limitations set forth
in Section 1(f)), this Warrant may be exercised by the Holder on any day on or after the Initial Exercisability Date (an “Exercise Date”), in whole or in part, by delivery (whether via facsimile or otherwise) of a written
notice, in the form attached hereto as Exhibit A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant. Within one (1) Trading Day following an exercise of this Warrant as aforesaid, the
Holder shall deliver payment to the Company of an amount equal to the Exercise Price in effect on the date of such exercise multiplied by the number of Warrant Shares as to which this Warrant was so exercised (the “Aggregate Exercise
Price”) in cash or via wire transfer of immediately available funds if the Holder did not notify the Company in such Exercise Notice that such exercise was made pursuant to a Cashless Exercise (as defined in Section 1(d)). The Holder
shall not be required to deliver the original of this Warrant in order to effect an exercise hereunder. Execution and delivery of an Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of
the original of this Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares. Execution and delivery of an Exercise Notice for all of the then-remaining Warrant Shares shall have the same effect
as cancellation of the original of this Warrant after delivery of the Warrant Shares in accordance with the terms hereof. On or before the first (1st) Trading Day following the date on which
the Company has received an Exercise Notice, the Company shall transmit by facsimile an acknowledgment of confirmation of receipt of such Exercise Notice, in the form attached hereto as Exhibit B, to the Holder and the
Company’s transfer agent (the “Transfer Agent”). On or before the third (3rd) Trading Day following the date on which the Company has received such Exercise 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 of such Warrant Shares initiated on the applicable Exercise Date), the Company shall (X) provided that the Transfer
Agent is participating in The Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program, upon the request of the Holder, credit such aggregate number of shares of Common Stock to which the Holder is entitled
pursuant to such exercise to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer
Program, issue and deliver to the Holder or, at the Holder’s instruction pursuant to the Exercise Notice, the Holder’s agent or designee, in each case, sent by reputable overnight courier to the address as specified in the applicable
Exercise Notice, a certificate, registered in the Company’s share register in the name of the Holder or its designee (as indicated in the applicable Exercise Notice), for the number of shares of Common Stock to which the Holder is entitled
pursuant to such exercise. Upon delivery of an Exercise Notice, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of
the date such Warrant Shares are credited to the Holder’s DTC account or the date of delivery of the certificates evidencing such Warrant Shares (as the case may be). If this Warrant is submitted in connection with any exercise pursuant to this
Section 1(a) and the number of Warrant Shares represented by this Warrant submitted for exercise is greater than the number of Warrant Shares being acquired upon an exercise, then, at the request of the Holder, the Company shall as soon as
practicable and in no event later than three (3) Business Days after any exercise and at its own expense, issue and deliver to the Holder (or its designee) a new Warrant (in accordance with Section 7(d)) representing the right to 

  
 2 

 
purchase the number of Warrant Shares purchasable immediately prior to such exercise under this Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised. No
fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock to be issued shall be rounded up to the nearest whole number. The Company shall pay any and all taxes and fees
which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant. Notwithstanding the foregoing, except in the case where an exercise of this Warrant is validly made pursuant to a Cashless Exercise (as
defined in Section 1(d)), the Company’s failure to deliver Warrant Shares to the Holder on or prior to the second (2nd) Trading Day after the Company’s receipt of the Aggregate Exercise Price shall not be deemed to be a breach of
this Warrant. Notwithstanding anything to the contrary contained in this Warrant or the Registration Rights Agreement, the Company shall cause the Transfer Agent to deliver unlegended shares of Common Stock to the Holder (or its designee) in
connection with any sale of Registrable Securities (as defined in the Registration Rights Agreement) with respect to which the Holder has entered into a contract for sale, and delivered a copy of the prospectus included as part of the particular
Registration Statement (as defined in the Registration Rights Agreement) to the extent applicable, after the effective date of such Registration Statement and prior to the Holder’s receipt of the notice of a Grace Period (as defined in the
Registration Rights Agreement) and for which the Holder has not yet settled. 
 (b) Exercise Price. For purposes of this Warrant,
“Exercise Price” means $2.25, subject to adjustment as provided herein. 
 (c) Company’s Failure to Timely Deliver
Securities. If the Company shall fail, for any reason or for no reason, to issue to the Holder within the later of (i) three (3) Trading Days after receipt of the applicable Exercise 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 of such Warrant Shares initiated on the applicable Exercise Date) and (ii) two (2) Trading Days after the Company’s receipt of the Aggregate
Exercise Price (or valid notice of a Cashless Exercise) (such later date, the “Share Delivery Deadline”), if either (I) the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, a
certificate for the number of Warrant Shares to which the Holder is entitled and register such Warrant Shares on the Company’s share register or, if the Transfer Agent is participating in the DTC Fast Automated Securities Transfer Program, to
credit the Holder’s balance account with DTC for such number of Warrant Shares to which the Holder is entitled upon the Holder’s exercise of this Warrant (as the case may be) or (II) if the Registration Statement covering the resale of the
Warrant Shares that are the subject of the Exercise Notice (the “Unavailable Warrant Shares”) is not available for the resale of such Unavailable Warrant Shares and the Company fails to promptly, but in no event later than as
required pursuant to the Registration Rights Agreement (x) so notify the Holder and (y) deliver the Warrant Shares electronically without any restrictive legend by crediting such aggregate number of Warrant Shares to which the Holder is
entitled pursuant to such exercise to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal At Custodian system (the event described in the immediately foregoing clause (II) is hereinafter referred as a
“Notice Failure” and together with the event described in clause (I) above, a “Delivery Failure”), and if on or after such Share Delivery Deadline 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 all or any portion of the number of Warrant Shares, or a sale of a number of 

  
 3 

 
shares of Common Stock equal to all or any portion of the number of Warrant Shares, issuable upon such exercise that the Holder so anticipated receiving from the Company, then, in addition to
all other remedies available to the Holder, the Company shall, within three (3) Trading Days after 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 and other out-of-pocket expenses, if any) for the shares of Common Stock so purchased (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 or credit the Holder’s balance account with DTC for the number of Warrant Shares to which the Holder is entitled upon the
Holder’s exercise hereunder (as the case may be) (and to issue such Warrant Shares) shall terminate, or (II) promptly honor its obligation to so issue and deliver to the Holder a certificate or certificates representing such Warrant Shares or
credit the Holder’s balance account with DTC for the number of Warrant Shares to which the Holder is entitled upon the Holder’s exercise 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 (A) such number of Warrant Shares multiplied by (B) the lowest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date of the applicable Exercise Notice and
ending on the date of such issuance and payment under this clause (II). 
 (d) Cashless Exercise. Notwithstanding anything
contained herein to the contrary (other than Section 1(f) below), if at the time of exercise hereof a Registration Statement (as defined in the Registration Rights Agreement (as defined in the Securities Purchase Agreement)) is not effective
(or the prospectus contained therein is not available for use) for the resale by the Holder of all of the Warrant Shares, then the Holder may, in its sole discretion, exercise this Warrant in whole or in part and, in lieu of making the cash payment
otherwise contemplated to be made to the Company upon such exercise in payment of the Aggregate Exercise Price, elect instead to receive upon such exercise the “Net Number” of Warrant Shares determined according to the following formula (a
“Cashless Exercise”): 
 Net Number = (A x B) - (A x C)  

                       
             D 
 For purposes of the foregoing formula: 

A= the total number of shares with respect to which this Warrant is then being exercised. 

B = the quotient of (x) the sum of the VWAP of the Common Stock of each of the twenty (20) Trading Days ending at the close of
business on the Principal Market immediately prior to the time of exercise as set forth in the applicable Exercise Notice, divided by (y) twenty (20). 

C = the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise. 

D = as applicable: (i) the Closing Sale Price of the Common Stock on the Trading Day immediately preceding the date of the applicable
Exercise Notice if 

  
 4 

 
such Exercise Notice is (1) both executed and delivered pursuant to Section 1(a) hereof on a day that is not a Trading Day or (2) both executed and delivered pursuant to
Section 1(a) hereof on a Trading Day prior to the opening of “regular trading hours” (as defined in Rule 600(b)(64) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) the Bid Price of the
Common Stock as of the time of the Holder’s execution of the applicable Exercise Notice if such Exercise Notice is executed during “regular trading hours” on a Trading Day and is delivered within two (2) hours thereafter pursuant
to Section 1(a) hereof, or (iii) the Closing Sale Price of the Common Stock on the date of the applicable Exercise Notice if the date of such Exercise Notice is a Trading Day and such Exercise Notice is both executed and delivered pursuant
to Section 1(a) hereof after the close of “regular trading hours” on such Trading Day. 
 For purposes of Rule 144(d)
promulgated under the 1933 Act, as in effect on the Subscription Date, it is intended that the Warrant Shares issued in a Cashless Exercise shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be
deemed to have commenced, on the date this Warrant was originally issued pursuant to the Securities Purchase Agreement 
 (e)
Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the number of Warrant Shares to be issued pursuant to the terms hereof, the Company shall promptly issue to the Holder the
number of Warrant Shares that are not disputed and resolve such dispute in accordance with Section 13. 
 (f) Limitations on
Exercises. 
 (i) Beneficial Ownership Limitation. The Company shall not effect the exercise of any portion of
this Warrant, and the Holder shall not have the right to exercise any portion of this Warrant, pursuant to the terms and conditions of this Warrant and any such exercise shall be null and void and treated as if never made, to the extent that after
giving effect to such exercise, 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 exercise. 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 exercise of this Warrant 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) exercise of the remaining, unexercised portion of this Warrant beneficially owned by the Holder or any of the other Attribution Parties and (B) exercise or conversion of the unexercised or unconverted portion of any other
securities of the Company (including, without limitation, any convertible notes or convertible preferred stock or warrants, including other SPA 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 1(f)(i). For purposes of this Section 1(f)(i), beneficial ownership shall be 

  
 5 

 
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 exercise of this
Warrant without exceeding the Maximum Percentage, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (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 an Exercise 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 (i) notify the Holder in writing of the number of shares of Common Stock then outstanding and, to the extent that such Exercise Notice would otherwise cause the Holder’s beneficial
ownership, as determined pursuant to this Section 1(f)(i), to exceed the Maximum Percentage, the Holder must notify the Company of a reduced number of Warrant Shares to be purchased pursuant to such Exercise Notice (the number of shares by
which such purchase is reduced, the “Reduction Shares”) and (ii) as soon as reasonably practicable, the Company shall return to the Holder any exercise price paid by the Holder for the Reduction Shares. 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 Warrant, 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 exercise of this Warrant 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. As
soon as reasonably practicable after the issuance of the Excess Shares has been deemed null and void, the Company shall return to the Holder the exercise price paid by the Holder for 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 SPA Warrants 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 Warrant 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 

  
 6 

 inability to exercise this Warrant pursuant to this paragraph shall have any effect on the
applicability of the provisions of this paragraph with respect to any subsequent determination of exercisability. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of
this Section 1(f)(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 1(f)(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 Warrant. 

(ii) Principal Market Regulation. The Company shall not issue any shares of Common Stock upon the exercise of this
Warrant if the issuance of such shares of Common Stock (taken together with the issuance of such shares upon the exercise of the SPA Warrants and the conversion of the Preferred Shares, the Notes or otherwise pursuant to the terms of the Notes, the
Certificate of Designations or the SPA Warrants) would exceed the aggregate number of shares of Common Stock which the Company may issue upon exercise or conversion or otherwise pursuant to the terms of the Notes, the Certificate of Designations or
the SPA Warrants (as the case may be) of the Warrants and the Notes 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, 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 outside 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, any of the Preferred Shares or any of the SPA Warrants or otherwise pursuant to the terms of the Notes, the
Certificate of Designations or the SPA Warrants, 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 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 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 SPA Warrants, the transferee
shall be allocated a pro rata portion of such Buyer’s Exchange Cap Allocation with respect to such portion of such SPA Warrants 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, Preferred Shares and SPA Warrants, 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 and Preferred Shares and such holder’s exercise in full of such SPA Warrants shall be allocated, to the respective
Exchange Cap Allocations of the remaining holders of Preferred Shares Notes and related SPA Warrants on a pro rata basis in proportion to the shares of Common Stock 

  
 7 

 
underlying the Notes and related SPA Warrants then held by each such holder of Notes and related SPA Warrants. In the event that the Company is then prohibited from issuing any shares of Common
Stock pursuant to this Section 1(f)(ii) (the “Exchange Cap Shares”), in lieu of issuing and delivering such Exchange Cap Shares to the Holder, the Company shall pay cash to the Holder in exchange for the cancellation of such
portion of this Warrant exercisable into such Exchange Cap Shares (the “Exchange Cap Payment Amount”) at a price equal to the sum of (x) the product of (A) such number of Exchange Cap Shares and (B) 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 Exercise Notice with respect to such Exchange Cap Shares to the Company and ending on the date of such payment
under this Section 1(f)(ii) and (y) 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 Exchange Cap Shares, any brokerage commissions
and other out-of-pocket expenses, if any, of the Holder incurred in connection therewith. 
 (g) Insufficient Authorized Shares. From
and after the Share Reservation Deadline (as defined in the Notes), the Company shall at all times keep reserved for issuance under this Warrant a number of shares of Common Stock at least equal to 200% of the maximum number of shares of Common
Stock as shall be necessary to satisfy the Company’s obligation to issue shares of Common Stock hereunder (without regard to any limitation otherwise contained herein with respect to the number of shares of Common Stock that may be acquirable
upon exercise of this Warrant). If, notwithstanding the foregoing, and not in limitation thereof, at any time after the Share Reservation Deadline, while any of the SPA Warrants 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 exercise of the SPA Warrants at least a number of shares of Common Stock (the “Required Reserve Amount”) equal to 200% of the
maximum number of shares of Common Stock as shall from time to time be necessary to effect the exercise of all of the SPA Warrants then outstanding (without regard to any limitation otherwise contained in the SPA Warrants with respect to the number
of shares of Common Stock that may be acquirable upon exercise of the SPA Warrants) (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 all the SPA Warrants 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 seventy five (75) 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. In the event that the Company is prohibited from issuing shares of Common Stock upon an exercise of this Warrant 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 “Authorization Failure Shares”), in lieu of
delivering such Authorization Failure Shares to the Holder, the Company shall pay cash in exchange for the cancellation of such portion of this Warrant 

  
 8 

 
exercisable into such Authorized Failure Shares at a price equal to the sum of (i) the product of (x) such number of Authorization 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 Exercise Notice with respect to such Authorization Failure Shares to the Company and ending on the date of such issuance and
payment under this Section 1(g); 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 Authorization Failure Shares, any
brokerage commissions and other out-of-pocket expenses, if any, of the Holder incurred in connection therewith. 
 (h) Holder Alternate
Exercise. 
 (i) General. Notwithstanding anything herein to the contrary, at any time during any Event of Default
Redemption Right Period (as defined in the Notes) (assuming, for such purpose, that the Notes remain outstanding as of such time of determination), the Company shall within one (1) Business Day deliver an Event of Default Notice (as defined in
the Notes) via facsimile and overnight courier (with next day delivery specified) (each, an “Alternate Exercise Eligibility Notice”) to the Holder. At any time during any Event of Default Redemption Right Period (as defined in the
Notes) (each, an “Alternate Exercise Eligibility Date”), the Holder may, at such Holder’s option, exercise (each, a “Holder Alternate Exercise”) all, or any part of, this Warrant (such portion of this Warrant being
exercised, the “Holder Alternate Exercise Amount”) into Common Stock at the Alternate Exercise Price. 

(ii) Holder Alternate Exercise. At any time during after the Alternate Exercise Eligibility Date, the Holder may
voluntarily exercise any Holder Alternate Exercise Amount pursuant to Section 1(a) (with “Alternate Exercise Price” replacing “Exercise Price” for all purposes hereunder with respect to such Holder Alternate Exercise)
by designating in the Exercise Notice delivered pursuant to Section 1(a) that the Holder is electing to use the Alternate Exercise Price for such Exercise. Notwithstanding anything to the contrary in this Section 1(h), but subject to
Section 1(f), until the Company delivers Common Stock representing the Holder Alternate Exercise Amount to the Holder, such Holder Alternate Exercise Amount may be exercised by the Holder into Common Stock pursuant to Section 1(a) without
regard to this Section 1(h). 
 2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and number of Warrant Shares
issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 2. 
 (a) Stock
Dividends and Splits. Without limiting any provision of Section 2(b) or Section 4, if the Company, at any time on or after the date of the Securities Purchase Agreement, (i) pays a stock dividend on one or more classes of its then
outstanding shares of Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more
classes of its then outstanding shares of Common Stock into a larger number of shares or (iii) combines (by combination, reverse stock split or otherwise) one or more classes of its then outstanding shares of Common Stock into a smaller number
of shares, then in each such 

  
 9 

 
case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately before such event and of which the
denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of
stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination. If any
event requiring an adjustment under this paragraph occurs during the period that an Exercise Price is calculated hereunder, then the calculation of such Exercise Price shall be adjusted appropriately to reflect such event. 

(b) Adjustment Upon Issuance of Shares of Common Stock. If and whenever on or after the date of the Securities Purchase Agreement, the
Company issues or sells, or in accordance with this Section 2 is deemed to have issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the account of the Company, but
excluding any Excluded Securities issued or sold or deemed to have been issued or sold) for a consideration per share (the “New Issuance Price”) less than a price equal to the Exercise Price in effect immediately prior to such
issuance or sale or deemed issuance or sale (such Exercise Price then in effect is referred to as the “Applicable Price”) (the foregoing a “Dilutive Issuance”), then immediately after such Dilutive Issuance, the
Exercise Price then in effect shall be reduced to an amount equal to the New Issuance Price. For all purposes of the foregoing (including, without limitation, determining the adjusted Exercise Price and the New Issuance Price under this
Section 2(b)), the following shall be applicable: 
 (i) Issuance of Options. If the Company in any manner grants
or sells any Options and the lowest price per share for which one share of Common Stock is at any time issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any
such Option or otherwise pursuant to the terms thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such
Option for such price per share. For purposes of this Section 2(b)(i), the “lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Options or upon conversion, exercise or exchange of any
Convertible Securities issuable upon exercise of any such Option or otherwise pursuant to the terms thereof” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the
Company with respect to any one share of Common Stock upon the granting or sale of such Option, upon exercise of such Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option or otherwise
pursuant to the terms thereof and (y) the lowest exercise price set forth in such Option for which one share of Common Stock is issuable upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible
Securities issuable upon exercise of any such Option or otherwise pursuant to the terms thereof minus (2) the sum of all amounts paid or payable to the holder of such Option (or any other Person) upon the granting or sale of such Option, upon
exercise of such Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option or otherwise pursuant to the terms thereof plus the value of any other consideration

  
 10 

 
received or receivable by, or benefit conferred on, the holder of such Option (or any other Person). Except as contemplated below, no further adjustment of the Exercise Price shall be made upon
the actual issuance of such shares of Common Stock or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities.

 (ii) Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities
and the lowest price per share for which one share of Common Stock is at any time issuable upon the conversion, exercise or exchange thereof or otherwise pursuant to the terms thereof is less than the Applicable Price, then such share of Common
Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section 2(b)(ii), the “lowest
price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof or otherwise pursuant to the terms thereof” shall be equal to (1) the lower of (x) the sum of the lowest amounts of
consideration (if any) received or receivable by the Company with respect to one share of Common Stock upon the issuance or sale of the Convertible Security and upon conversion, exercise or exchange of such Convertible Security and otherwise
pursuant to the terms thereof and (y) the lowest conversion price set forth in such Convertible Security for which one share of Common Stock is issuable upon conversion, exercise or exchange thereof or otherwise pursuant to the terms thereof
minus (2) the sum of all amounts paid or payable to the holder of such Convertible Security (or any other Person) upon the issuance or sale of such Convertible Security plus the value of any other consideration received or receivable by, or
benefit conferred on, the holder of such Convertible Security (or any other Person). Except as contemplated below, no further adjustment of the Exercise Price shall be made upon the actual issuance of such shares of Common Stock upon conversion,
exercise or exchange of such Convertible Securities or otherwise pursuant to the terms thereof, and if any such issuance or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of this Warrant has been or is
to be made pursuant to other provisions of this Section 2(b), except as contemplated below, no further adjustment of the Exercise Price shall be made by reason of such issuance or sale. 

(iii) Change in Option Price or Rate of Conversion. If the purchase or exercise price provided for in any Options, the
additional consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exercisable or exchangeable for shares of Common Stock
increases or decreases at any time, the Exercise Price in effect at the time of such increase or decrease shall be adjusted to the Exercise Price which would have been in effect at such time had such Options or Convertible Securities provided for
such increased or decreased purchase price, additional consideration or increased or decreased conversion rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 2(b)(iii), if the terms of any
Option or Convertible Security that was outstanding as of the date of issuance of this Warrant are increased or decreased in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the shares of
Common Stock deemed issuable upon exercise, 

  
 11 

 
conversion or exchange thereof shall be deemed to have been issued as of the date of such increase or decrease. No adjustment pursuant to this Section 2(b) shall be made if such adjustment
would result in an increase of the Exercise Price then in effect. 
 (iv) Calculation of Consideration Received. If
any Option and/or Convertible Security and/or Adjustment Right is issued in connection with the issuance or sale or deemed issuance or sale of any other securities of the Company (as determined by the Holder, the “Primary Security”,
and such Option and/or Convertible Security and/or Adjustment Right, the “Secondary Securities”), together comprising one integrated transaction, the aggregate consideration per share of Common Stock with respect to such Primary
Security shall be deemed to be equal to the difference of (x) the lowest price per share for which one share of Common Stock was issued (or was deemed to be issued pursuant to Section 2(b)(i) or 2(b)(ii) above, as applicable) in such
integrated transaction (or one or more transactions if such issuances or sales or deemed issuances or sales of securities of the Company either (A) have at least one investor or purchaser in common, (B) are consummated in reasonable
proximity to each other and/or (C) are consummated under the same plan of financing) solely with respect to such Primary Security, minus (y) with respect to such Secondary Securities, the sum of (I) the Black Scholes Consideration
Value of each such Option, if any, (II) the fair market value (as determined by the Holder) or the Black Scholes Consideration Value, as applicable, of such Adjustment Right, if any, and (III) the fair market value (as determined by the Holder) of
such Convertible Security, if any, in each case, as determined on a per share basis in accordance with this Section 2(b)(iv). If any shares of Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or
sold for cash, the consideration received therefor (for the purpose of determining the consideration paid for such Common Stock, Option or Convertible Security, but not for the purpose of the calculation of the Black Scholes Consideration Value)
will be deemed to be the net amount of consideration received by the Company therefor. If any shares of Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration received
by the Company (for the purpose of determining the consideration paid for such Common Stock, Option or Convertible Security, but not for the purpose of the calculation of the Black Scholes Consideration Value) will be the fair value of such
consideration, except where such consideration consists of publicly traded securities, in which case the amount of consideration received by the Company for such securities will be the arithmetic average of the VWAPs of such security for each of the
five (5) Trading Days immediately preceding the date of receipt. If any shares of Common Stock, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the
surviving entity, the amount of consideration therefor (for the purpose of determining the consideration paid for such Common Stock, Option or Convertible Security, but not for the purpose of the calculation of the Black Scholes Consideration Value)
will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such shares of Common Stock, Options or Convertible Securities, as the case may be. The fair value of any
consideration other than cash or publicly traded securities will be determined jointly by the Company and the Holder. If such parties are unable to reach agreement within ten (10) days after the occurrence of an event requiring valuation (the
“Valuation Event”), the fair value of 

  
 12 

 
such consideration will be determined within five (5) Trading Days after the tenth (10th) day following such Valuation Event by an
independent, reputable appraiser jointly selected by the Company and the Holder. The determination of such appraiser shall be final and binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the
Company. 
 (v) Record Date. If the Company takes a record of the holders of shares of Common Stock for the purpose of
entitling them (A) to receive a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to subscribe for or purchase shares of Common Stock, Options or Convertible Securities, then such
record date will be deemed to be the date of the issuance or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such
right of subscription or purchase (as the case may be). 
 (vi) Treatment of Outstanding Excluded Preferred
Securities. For purposes of this Section 2(b), no adjustment of the Exercise Price shall be made with respect to any Excluded Preferred Securities (if at all) unless and until shares of Common Stock (whether upon conversion, exchange,
redemption or otherwise) are actually issued with respect to any such Excluded Preferred Securities (each, a “Preferred Securities Related Issuance”). For the avoidance of doubt, other than with respect to an adjustment to the
Exercise Price upon a Preferred Securities Related Issuance in accordance with this Section 2(b), a change in the deemed conversion price of the Excluded Preferred Securities in accordance with the terms of such Excluded Preferred Securities as
in effect as of the Subscription Date shall not cause any adjustment of the Exercise Price under this Section 2(b). Notwithstanding anything in this Section 2(b)(vi) to the contrary, nothing in this Section 2(b)(vi) shall be deemed to
amend or limit any rights of the Holder to exercise this Warrant pursuant to Section 2(d) below. 
 (c) Number of Warrant
Shares. Simultaneously with any adjustment to the Exercise Price pursuant to paragraphs (a), (b), (d) or (e) of this Section 2, the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or
decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment
(without regard to any limitations on exercise contained herein). 
 (d) Holder’s Right of Alternative Exercise Price Following
Issuance of Certain Options or Convertible Securities. In addition to and not in limitation of the other provisions of this Section 2, 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 (any such securities, “Variable Price Securities”) that are convertible into or exchangeable or exercisable for shares of Common Stock at a price which varies or may vary with the market
price of the Common Shares, 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 

  
 13 

 
written notice thereof via facsimile and overnight courier to the Holder on the date of issuance of such Convertible Securities or Options. From and after the date the Company issues any such
Convertible Securities or Options with a Variable Price, the Holder shall have the right, but not the obligation, in its sole discretion to substitute the Variable Price for the Exercise Price upon exercise of this Warrant by designating in the
Exercise Notice delivered upon any exercise of this Warrant that solely for purposes of such exercise the Holder is relying on the Variable Price rather than the Exercise Price then in effect. The Holder’s election to rely on a Variable Price
for a particular exercise of this Warrant shall not obligate the Holder to rely on a Variable Price for any future exercises of this Warrant. 

(e) Stock Combination Event Adjustment. If at any time and from time to time on or after the Issuance Date there occurs any stock
split, stock dividend, stock combination recapitalization or other similar transaction involving the Common Stock (each, a “Stock Combination Event”, and such date thereof, the “Stock Combination Event Date”) and
the Event Market Price is less than the Exercise Price then in effect (after giving effect to the adjustment in clause (b) above), then on the sixteenth (16th) Trading Day immediately
following such Stock Combination Event, the Exercise Price then in effect on such sixteenth (16th) Trading Day (after giving effect to the adjustment in clause (b) above) shall be
reduced (but in no event increased) to the Event Market Price. 
 (f) Other Events. In the event that the Company (or any Subsidiary
(as defined in the Securities Purchase Agreement)) 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 2 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 Exercise Price and the number of Warrant Shares (if applicable) so as to protect the rights of the Holder, provided that no such
adjustment pursuant to this Section 2(e) will increase the Exercise Price or decrease the number of Warrant Shares as otherwise determined pursuant to this Section 2, 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 and whose fees and expenses shall be borne by the Company. 
 (g)
Calculations. All calculations under this Section 2 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 issuance or sale of Common Stock. 

(h) Voluntary Adjustment By Company. The Company may at any time during the term of this Warrant, with the prior written consent of the
Required Holders, reduce the then current Exercise Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company. 

  
 14 

 3. RIGHTS UPON DISTRIBUTION OF ASSETS. In addition to any adjustments pursuant to Section 2 above, if
the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to 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) (a “Distribution”), at any time after the issuance
of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon
complete exercise of this Warrant (without regard to any limitations or restrictions on exercise of this Warrant, including without limitation, the Maximum Percentage) immediately before the date of which a record is taken for such Distribution, 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 participation in such Distribution (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 such extent (and shall not be entitled
to beneficial ownership of such shares of Common Stock as a result of such Distribution (and beneficial ownership) to such extent) 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). 
 4.
PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS. 
 (a) Purchase Rights. In addition to any adjustments pursuant to Section 2
above, 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 the record holders of any class of shares 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 exercise of this Warrant (without regard to any limitations or restrictions on exercise of this Warrant, including without limitation, the Maximum Percentage) immediately before 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, issuance 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 such extent (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 such extent) and such Purchase Right to
such extent 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 right (and any Purchase Right granted, issued or sold on such initial Purchase Right or on any subsequent Purchase Right held similarly in abeyance) to the same extent as if there had been no such limitation). 

  
 15 

 (b) Fundamental Transactions. The Company shall not enter into or be party to a
Fundamental Transaction unless (i) the Successor Entity assumes in writing all of the obligations of the Company under this Warrant and the other Transaction Documents (as defined in the Securities Purchase Agreement) in accordance with the
provisions of this Section 4(b) pursuant to written agreements in form and substance satisfactory to the Holder and approved by the Holder prior to such Fundamental Transaction, including agreements to deliver to the Holder in exchange for this
Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant, including, without limitation, which is exercisable for a corresponding number of shares of capital stock
equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the
exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such adjustments to the number
of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction) and (ii) the Successor Entity (including its Parent
Entity) is a publicly traded corporation whose common stock is quoted on or listed for trading on an Eligible Market. Upon the consummation of each Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from
and after the date of the applicable Fundamental Transaction, the provisions of this Warrant and the other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and
power of the Company and shall assume all of the obligations of the Company under this Warrant and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of each
Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon exercise of this Warrant at any time after the consummation of the applicable 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 3 and 4(a) above, which shall continue to be receivable thereafter)) issuable upon the exercise of this Warrant prior to the
applicable Fundamental Transaction, such shares of publicly traded common stock (or its equivalent) of the Successor Entity (including its Parent Entity) which the Holder would have been entitled to receive upon the happening of the applicable
Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant), as adjusted in accordance with the provisions of this Warrant.
Notwithstanding the foregoing, and without limiting Section 1(f) hereof, the Holder may elect, at its sole option, by delivery of written notice to the Company to waive this Section 4(b) to permit the Fundamental Transaction without the
assumption of this Warrant. In addition to and not in substitution for any other rights hereunder, prior to the consummation of each 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 insure that the Holder will thereafter have the right to receive upon an exercise of this
Warrant at any time after the consummation of the applicable Fundamental Transaction but prior to the Expiration Date, in 

  
 16 

 
lieu of the shares of the Common Stock (or other securities, cash, assets or other property (except such items still issuable under Sections 3 and 4(a) above, which shall continue to be
receivable thereafter)) issuable upon the exercise of the Warrant prior to such Fundamental Transaction, such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights)
which the Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the
exercise of this Warrant). Provision made pursuant to the preceding sentence shall be in a form and substance reasonably satisfactory to the Holder. 

(c) Black Scholes Value. 

(i) Fundamental Transaction Redemption. Notwithstanding the foregoing and the provisions of Section 4(b) above, at
the request of the Holder delivered at any time commencing on the earliest to occur of (x) the public disclosure of any Fundamental Transaction, (y) the consummation of any Fundamental Transaction and (z) the Holder first becoming
aware of any Fundamental Transaction through the date that is ninety (90) days after the public disclosure of the consummation of such Fundamental Transaction by the Company pursuant to a Current Report on Form 8-K filed with the SEC, the
Company or the Successor Entity (as the case may be) shall purchase this Warrant from the Holder on the date of such request by paying to the Holder cash in an amount equal to the Black Scholes Value. Notwithstanding the foregoing, a Permitted JV
Transfer (as defined in the Notes) shall not be a Fundamental Transaction for purposes of this Section 4(c)(i). 
 (ii)
Event of Default Redemption. Notwithstanding the foregoing and the provisions of Section 4(b) above, at the request of the Holder delivered at any time after the occurrence of an Event of Default (as defined in the Notes)(assuming for
such purpose that the Notes remain outstanding), the Company or the Successor Entity (as the case may be) shall purchase this Warrant from the Holder on the date of such request by paying to the Holder cash in an amount equal to the Event of Default
Black Scholes Value. 
 (d) Application. The provisions of this Section 4 shall apply similarly and equally to successive
Fundamental Transactions and Corporate Events and shall be applied as if this Warrant (and any such subsequent warrants) were fully exercisable and without regard to any limitations on the exercise of this Warrant (provided that the Holder shall
continue to be entitled to the benefit of the Maximum Percentage, applied however with respect to shares of capital stock registered under the 1934 Act and thereafter receivable upon exercise of this Warrant (or any such other warrant)). 

5. 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, issuance 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 Warrant, and will at all times in good faith 

  
 17 

 
carry out all the provisions of this Warrant and take all action as may be required to protect the rights of the Holder. Without limiting the generality of the foregoing, the Company
(a) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, (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 non-assessable shares of Common Stock upon the exercise of this Warrant, and (c) shall, in accordance with Section 1(g) above, after the Share Reservation Deadline, so long as any of the
SPA Warrants are outstanding, take all action necessary to reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting the exercise of the SPA Warrants, 200% of the maximum number of
shares of Common Stock as shall from time to time be necessary to effect the exercise of the SPA Warrants then outstanding (without regard to any limitations on exercise). 

6. WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, the Holder, solely in its capacity as a holder of this
Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in its capacity as the
Holder of this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger,
conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Warrant Shares which it is then entitled to receive upon the due exercise of this Warrant. In
addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are
asserted by the Company or by creditors of the Company. Notwithstanding this Section 6, the Company shall provide the Holder with copies of the same notices and other information given to the stockholders of the Company generally,
contemporaneously with the giving thereof to the stockholders. 
 7. REISSUANCE OF WARRANTS. 

(a) Transfer of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon the
Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 7(d)), registered as the Holder may request, representing the right to purchase the number of Warrant Shares being transferred by
the Holder and, if less than the total number of Warrant Shares then underlying this Warrant is being transferred, a new Warrant (in accordance with Section 7(d)) to the Holder representing the right to purchase the number of Warrant Shares not
being transferred. 
 (b) Lost, Stolen or Mutilated Warrant. Upon receipt by the Company of evidence reasonably satisfactory to the
Company of the loss, theft, destruction or mutilation of this Warrant (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 Warrant, the Company shall execute and deliver to the Holder a new Warrant (in
accordance with Section 7(d)) representing the right to purchase the Warrant Shares then underlying this Warrant. 

  
 18 

 (c) Exchangeable for Multiple Warrants. This Warrant is exchangeable, upon the surrender
hereof by the Holder at the principal office of the Company, for a new Warrant or Warrants (in accordance with Section 7(d)) representing in the aggregate the right to purchase the number of Warrant Shares then underlying this Warrant, and each
such new Warrant will represent the right to purchase such portion of such Warrant Shares as is designated by the Holder at the time of such surrender; provided, however, no warrants for fractional shares of Common Stock shall be given. 

(d) Issuance of New Warrants. Whenever the Company is required to issue a new Warrant pursuant to the terms of this Warrant, such new
Warrant (i) shall be of like tenor with this Warrant, (ii) shall represent, as indicated on the face of such new Warrant, the right to purchase the Warrant Shares then underlying this Warrant (or in the case of a new Warrant being issued
pursuant to Section 7(a) or Section 7(c), the Warrant Shares designated by the Holder which, when added to the number of shares of Common Stock underlying the other new Warrants issued in connection with such issuance, does not exceed the
number of Warrant Shares then underlying this Warrant), (iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance Date, and (iv) shall have the same rights and conditions as this
Warrant. 
 8. NOTICES. Whenever notice is required to be given under this Warrant, unless otherwise provided herein, such notice shall be given in
accordance with Section 9(f) of the Securities Purchase Agreement. The Company shall provide the Holder with prompt written notice of all actions taken pursuant to this Warrant, including in reasonable detail a description of such action and
the reason therefor. Without limiting the generality of the foregoing, the Company will give written notice to the Holder (i) immediately upon each adjustment of the Exercise Price and the number of Warrant Shares, setting forth in reasonable
detail, and certifying, the calculation of such adjustment(s), (ii) at least fifteen (15) days prior to the date on which the Company closes its books or takes a record (A) with respect to any dividend or distribution upon the shares
of Common Stock, (B) with respect to any grants, issuances or sales of any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property to holders of shares of Common Stock or (C) for determining
rights to vote with respect to any Fundamental Transaction, dissolution or liquidation, provided in each case that such information shall be made known to the public prior to or in conjunction with such notice being provided to the Holder,
(iii) at least ten (10) Trading Days prior to the consummation of any Fundamental Transaction and (iv) within one (1) Business Day of the occurrence of an Event of Default (as defined in the Notes), setting forth in reasonable
detail any material events with respect to such Event of Default and any efforts by the Company to cure such Event of Default. To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding the
Company or any of its Subsidiaries, the Company shall simultaneously file such notice with the SEC (as defined in the Securities Purchase Agreement) pursuant to a Current Report on Form 8-K. It is expressly understood and agreed that the time of
execution specified by the Holder in each Exercise Notice shall be definitive and may not be disputed or challenged by the Company. 

  
 19 

 9. AMENDMENT AND WAIVER. Except as otherwise provided herein, the provisions of this Warrant (other than
Section 1(f)) may be amended and the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained the written consent of the Holder. No waiver shall be
effective unless it is in writing and signed by an authorized representative of the waiving party. 
 10. SEVERABILITY. If any provision of this
Warrant 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 Warrant so long as this Warrant 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). 
 11. GOVERNING
LAW. This Warrant shall be governed by and construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Warrant 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. 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 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. 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 WARRANT
OR ANY TRANSACTION CONTEMPLATED HEREBY. 
 12. CONSTRUCTION; HEADINGS. This Warrant shall be deemed to be jointly drafted by the Company and the
Holder and shall not be construed against any Person as the drafter hereof. The headings of this Warrant are for convenience of reference and shall not form part of, or affect the interpretation of, this Warrant. Terms used in this Warrant but
defined in the other Transaction Documents shall have the meanings ascribed to such terms on the Closing Date (as defined in the Securities Purchase Agreement) in such other Transaction Documents unless otherwise consented to in writing by the
Holder. 

  
 20 

 13. DISPUTE RESOLUTION. 

(a) Submission to Dispute Resolution. 

(i) In the case of a dispute relating to the Exercise Price, the Closing Sale Price, the Bid Price, Black Scholes Consideration
Value, Event of Default Black Scholes Value, Black Scholes Value or fair market value or the arithmetic calculation of the number of Warrant Shares (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 facsimile (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 Exercise Price, such Closing Sale
Price, such Bid Price, such Black Scholes Consideration Value, Event of Default Black Scholes Value, Black Scholes Value or such fair market value or such arithmetic calculation of the number of Warrant Shares (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.
