acquire the Warrant Shares issuable upon exercise thereof, in each case, for its own account and not with a view towards, or for resale in connection with, the public sale or distribution thereof in violation of applicable securities laws, except
pursuant to sales registered or exempted under the 1933 Act; provided, however, by making the representations herein, such Buyer does not agree, or make any representation or warranty, to hold any of the Securities for any minimum or other specific
term and reserves the right to dispose of the Securities at any time in accordance with or pursuant to a registration statement or an exemption from registration under the 1933 Act. Such Buyer does not presently have any agreement or understanding,
directly or indirectly, with any Person to distribute any of the Securities in violation of applicable securities laws.

 (c)
Reliance on Exemptions. Such Buyer understands that the Securities are being offered and sold to it in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that the Company
is relying in part upon the 

  
 3

the availability of such exemptions and the eligibility of such Buyer to acquire the Securities. 
 (d) Information. Such Buyer and
its advisors, if any, have been furnished with all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Securities that have been requested by such Buyer. Neither such
inquiries nor any other due diligence investigations conducted by such Buyer or its advisors, if any, or its representatives shall modify, amend or affect such Buyer’s right to rely on the Company’s representations and warranties contained
herein. Such Buyer and its advisors, if any, have been afforded the opportunity to ask questions of the Company. Such Buyer understands that its investment in the Securities involves a high degree of risk. Such Buyer has sought such accounting,
legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Securities.

governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities nor have such authorities passed upon or endorsed the merits of the offering of the
Securities. 
 (f) Transfer or Resale. Such Buyer understands that except as provided in the Registration Rights Agreement and
Section 4(h) hereof: (i) the Securities have not been and are not being registered under the 1933 Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (A) subsequently registered
thereunder, (B) such Buyer shall have delivered to the Company (if requested by the Company) an opinion of counsel to such Buyer, in a form reasonably acceptable to the Company, to the effect that such Securities to be sold, assigned or
transferred may be sold, assigned or transferred pursuant to an exemption from such registration, or (C) such Buyer provides the Company with reasonable assurance that such Securities can be sold, assigned or transferred pursuant to Rule 144 or
Rule 144A promulgated under the 1933 Act (or a successor rule thereto) (collectively, “Rule 144”); (ii) any sale of the Securities made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144, and
further, if Rule 144 is not applicable, any resale of the Securities under circumstances in which the seller (or the Person (as defined below) through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the 1933
Act) may require compliance with some other exemption under the 1933 Act or the rules and regulations of the SEC promulgated thereunder; and (iii) neither the Company nor any other Person is under any obligation to register the Securities under
the 1933 Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder. Notwithstanding the foregoing, the Securities may be pledged in connection with a bona fide margin account or other loan or financing
arrangement secured by the Securities and such pledge of Securities shall not be deemed to be a transfer, sale or assignment of the Securities hereunder, and no Buyer effecting a pledge of Securities shall be required to provide the Company with any
notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other Transaction Document (as defined in Section 3(b)), including, without limitation, this Section 2(f).

enforcement of applicable creditors’ rights and remedies. 
 (h) No Conflicts. The execution, delivery and performance by such
Buyer of this Agreement, the Collateral Agency Agreement and the Registration Rights Agreement and the consummation by such Buyer of the transactions contemplated hereby and thereby will not (i) result in a violation of the organizational
documents of such Buyer, or (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation
of, any agreement, indenture or instrument to which such Buyer is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws) applicable to such Buyer, except in
the case of clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which could not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of such Buyer to
perform its obligations hereunder.

the Transaction Documents (including all exhibits and schedules thereto) and has been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the

appendices included therein and financial statements, notes and schedules thereto and documents incorporated by reference therein being hereinafter referred to as the “SEC Documents”). The Company has delivered or has made available
to the Buyers or their respective representatives true, correct and complete copies of each of the SEC Documents not available on the EDGAR system. As of their respective dates, the SEC Documents complied in all material respects with the
requirements of the 1934 Act and the rules and regulations of the SEC promulgated thereunder applicable to the SEC Documents, and none of the SEC Documents, at the time they were filed with the SEC, contained any untrue statement of a material fact
or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. As of their respective dates, the financial
statements of the Company included in the SEC Documents complied in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto as in effect as of the time of filing. Such

Company as of the dates thereof and the results of its operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments which will not be material, either individually or in the
aggregate). No other information provided by or on behalf of the Company to any of the Buyers which is not included in the SEC Documents (including, without limitation, information referred to in Section 2(e) of this Agreement) contains any
untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein not misleading, in the light of the circumstance under which they are or were made. The Company is not currently contemplating
to amend or restate any of the financial statements (including, without limitation, any notes or any letter of the independent accountants of the Company with respect thereto) included in the SEC Documents (the “Financial
Statements”), nor is the Company currently aware of facts or circumstances which would require the Company to amend or restate any of the Financial Statements, in each case, in order for any of the Financials Statements to be in compliance
with GAAP and the rules and regulations of the SEC. The Company has not been informed by its independent accountants that they recommend that the Company amend or restate any of the Financial Statements or that there is any need for the Company to
amend or restate any of the Financial Statements. 
 (l) Absence of Certain Changes. Since the date of the Company’s most recent
audited financial statements contained in a Form 10-K, there has been no material adverse

or any of its Subsidiaries. Since the date of the Company’s most recent audited financial statements contained in a Form 10-K, neither the Company nor any of its Subsidiaries has (i) declared or paid any dividends, (ii) sold any
assets, individually or in the aggregate, outside of the ordinary course of business or (iii) made any capital expenditures, individually or in the aggregate, outside of the ordinary course of business. Neither the Company nor any of its
Subsidiaries has taken any steps to seek protection pursuant to any law or statute relating to bankruptcy, insolvency, reorganization, receivership, liquidation or winding up, nor does the Company or any Subsidiary have any knowledge or reason to
believe that any of their respective creditors intend to initiate involuntary bankruptcy proceedings or any actual knowledge of any fact which would reasonably lead a creditor to do so. The Company and its Subsidiaries, individually and on a
consolidated basis, are not as of the date hereof, and after giving effect to the transactions contemplated hereby to occur at the Closing, will not be Insolvent (as defined below). For purposes of this Section 3(l),
“Insolvent” means, (I) with respect to the Company and its Subsidiaries, on a consolidated basis, (i) the present fair saleable value of the Company’s and its Subsidiaries’ assets is less than the amount required
to pay the Company’s and its Subsidiaries’ total Indebtedness (as defined below), (ii) the Company and its Subsidiaries are unable to pay their debts and liabilities, subordinated, contingent or otherwise, as such debts and
liabilities become absolute and matured or (iii) the Company and its Subsidiaries intend to incur or believe that they will incur debts that would be beyond their ability to pay as such debts mature; and (II) with respect to the Company and
each Subsidiary, individually, (i) the present fair saleable value of the Company’s or such Subsidiary’s (as the case may be) assets is less than the amount required to pay its respective total Indebtedness, (ii) the Company or
such Subsidiary (as the case may be) is unable to pay its respective debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured or (iii) the Company or such Subsidiary (as the case
may be) intends to incur or believes that it will incur debts that would be beyond its respective ability to pay as such debts mature. Neither the Company nor any of its Subsidiaries has engaged in any business or in any transaction, and is not
about to engage in any business or in any transaction, for which the Company’s or such Subsidiary’s remaining assets constitute unreasonably small capital. 

(m) No Undisclosed Events, Liabilities, Developments or Circumstances. No event, liability, development or circumstance has occurred or
exists, or is reasonably expected to exist or occur with respect to the Company, any of its Subsidiaries or any of their respective businesses, properties, liabilities, prospects, operations (including results thereof) or condition (financial or
otherwise), that (i) would be required to be disclosed by the Company under applicable securities laws on a registration statement on Form S-1 filed with the SEC relating to an issuance and sale by the Company of its Common Stock and which has
not been publicly announced, (ii) could have a material adverse effect on any Buyer’s investment hereunder or (iii) could have a Material Adverse Effect. 

(n) Conduct of Business; Regulatory Permits. Neither the Company nor any of its Subsidiaries is in violation of any term of or in
default under its Certificate of Incorporation, any certificate of designation, preferences or rights of any other outstanding series of preferred stock of the Company or any of its Subsidiaries or Bylaws or their organizational charter, certificate
of formation or certificate of incorporation or bylaws, respectively. Neither the Company nor any 

  
 11 

 
of its Subsidiaries is in violation of any judgment, decree or order or any statute, ordinance, rule or regulation applicable to the Company or any of its Subsidiaries, and neither the Company
nor any of its Subsidiaries will conduct its business in violation of any of the foregoing, except in all cases for possible violations which could not, individually or in the aggregate, have a Material Adverse Effect. Except as set forth on
Schedule 3(e), without limiting the generality of the foregoing, the Company is not in violation of any of the rules, regulations or requirements of the Principal Market and has no knowledge of any facts or circumstances that could reasonably lead
to delisting or suspension of the Common Stock by the Principal Market in the foreseeable future. Since January 1, 2011, (i) the Common Stock has been listed or designated for quotation on the Principal Market, (ii) trading in the
Common Stock has not been suspended by the SEC or the Principal Market and (iii) except as set forth on Schedule 3(e), the Company has received no communication, written or oral, from the SEC or the Principal Market regarding the suspension or
delisting of the Common Stock from the Principal Market. The Company and each of its Subsidiaries possess all certificates, authorizations and permits issued by the appropriate regulatory authorities necessary to conduct their respective businesses,
except where the failure to possess such certificates, authorizations or permits would not have, individually or in the aggregate, a Material Adverse Effect, and neither the Company nor any such Subsidiary has received any notice of proceedings
relating to the revocation or modification of any such certificate, authorization or permit. 
 (o) Foreign Corrupt Practices.
Neither the Company, the Company’s subsidiary or any director, officer, agent, employee, nor any other person acting for or on behalf of the foregoing (individually and collectively, a “Company Affiliate”) have violated the
U.S. Foreign Corrupt Practices Act (the “FCPA”) or any other applicable anti-bribery or anti-corruption laws, nor has any Company Affiliate offered, paid, promised to pay, or authorized the payment of any money, or offered, given,
promised to give, or authorized the giving of anything of value, to any officer, employee or any other person acting in an official capacity for any Governmental Entity to any political party or official thereof or to any candidate for political
office (individually and collectively, a “Government Official”) or to any person under circumstances where such Company Affiliate knew or was aware of a high probability that all or a portion of such money or thing of value would be
offered, given or promised, directly or indirectly, to any Governmental Official, for the purpose of: 
 (i) (A) influencing any act or
decision of such Government Official in his/her official capacity, (B) inducing such Government Official to do or omit to do any act in violation of his/her lawful duty, (C) securing any improper advantage, or (D) inducing such

of the Company or any of its Subsidiaries, any corporation, partnership, trust or other Person in which any such officer, director, employee or affiliate has a substantial interest or is an employee, officer, director, affiliate, trustee or partner.

 (r) Equity Capitalization. Schedule 3(r) attached hereto summaries the authorized and outstanding equity capitalization of the
Company. No shares of Common Stock are held in treasury. All of such outstanding shares are duly authorized and have been, or upon issuance will be, validly issued and are fully paid and nonassessable. Schedule 3(r) sets forth the number of shares
of Common Stock that are (x) reserved for issuance pursuant to Convertible Securities (as defined below) (other than the Notes and the Warrants) and (y) that are, as of the date hereof, owned by Persons who are “affiliates” (as

Persons are “affiliates” for purposes of federal securities laws) of the Company or any of its Subsidiaries. Except as disclosed in the SEC Documents, to the Company’s knowledge, no Person owns 10% or more of the Company’s issued
and outstanding shares of Common Stock (calculated based on the assumption that all Convertible Securities (as defined below), whether or not presently exercisable or convertible, have been fully exercised or converted (as the case may be)
taking account of any limitations on exercise or conversion (including “blockers”) contained therein without conceding that such identified Person is a 10% stockholder for purposes of federal securities laws). (i) except as disclosed
on Schedule 3(r)(i), None of the Company’s or any Subsidiary’s capital stock is subject to preemptive rights or any other similar rights or Liens suffered or permitted by the Company or any Subsidiary; (ii) except as disclosed in
Schedule 3(r)(ii), there are no outstanding options, warrants, scrip, rights to subscribe to, calls or commitments of any character whatsoever relating to, or securities or rights convertible into, or exercisable or exchangeable for, any

liabilities or obligations required to be disclosed in the SEC Documents which are not so disclosed in the SEC Documents, other than those incurred in the ordinary course of the Company’s or its Subsidiaries’ respective businesses and
which, individually or in the aggregate, do not or could not have a Material Adverse Effect. The Company has furnished to the Buyers true, correct and complete copies of the Company’s Certificate of Incorporation, as amended and as in effect on
the date hereof (the “Certificate of Incorporation”), and the Company’s bylaws, as amended and as in effect on the date hereof (the “Bylaws”), and the terms of all Convertible Securities and the material rights

(G) all indebtedness referred to in clauses (A) through (F) above secured by (or for which the holder of such Indebtedness has an existing right, contingent or otherwise, to be secured by) any Lien upon or in any property or assets
(including accounts and contract rights) owned by any Person, even though the Person which owns such assets or property has not assumed or become liable for the payment of such indebtedness, and (H) all Contingent Obligations in respect of
indebtedness or obligations of others of the kinds referred to in clauses (A) through (G) above; (y) “Contingent Obligation” means, as to any Person, any direct or indirect liability, contingent or otherwise, of that
Person with respect to any indebtedness, lease, dividend or other obligation of another Person if the primary purpose or intent of the Person incurring such liability, or the primary effect thereof, is to provide assurance to the obligee of such
liability that such liability will be paid or discharged, or that any 

  
 14 

 
agreements relating thereto will be complied with, or that the holders of such liability will be protected (in whole or in part) against loss with respect thereto; and
(z) “Person” means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an unincorporated organization, any other entity and any Governmental Entity or any department or agency

court, public board, other Governmental Entity, self-regulatory organization or body pending or, to the knowledge of the Company, threatened against or affecting the Company or any of its Subsidiaries, the Common Stock or any of the Company’s
or its Subsidiaries’ officers or directors , whether of a civil or criminal nature or otherwise, in their capacities as such, except as set forth in Schedule 3(t). No director, officer or employee of the Company or any of its
subsidiaries has willfully violated 18 U.S.C. §1519 or engaged in spoliation in reasonable anticipation of litigation. Without limitation of the foregoing, there has not been, and to the knowledge of the Company, there is not pending or
contemplated, any investigation by the SEC involving the Company, any of its Subsidiaries or any current or former director or officer of the Company or any of its Subsidiaries. The SEC has not issued any stop order or other order suspending the
effectiveness of any registration statement filed by the Company under the 1933 Act or the 1934 Act. 
 (u) Insurance. The Company
and each of its Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as management of the Company believes to be prudent and customary in the businesses in which the Company
and its Subsidiaries are engaged. Neither the Company nor any such Subsidiary has been refused any insurance coverage sought or applied for, and neither the Company nor any such Subsidiary has any reason to believe that it will be unable to renew
its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not have a Material Adverse Effect. 

(v) Employee Relations. Neither the Company nor any of its Subsidiaries is a party to any collective bargaining agreement or employs
any member of a union. The Company and its Subsidiaries believe that their relations with their employees are good. No executive officer (as defined in Rule 501(f) promulgated under the 1933 Act) or other key employee of the Company or any of its
Subsidiaries has notified the Company or any such Subsidiary that such officer intends to leave the Company or any such Subsidiary or otherwise terminate such officer’s employment with the Company or any such Subsidiary. No executive officer or
other key employee of the Company or any of its Subsidiaries is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement, non-competition agreement, or
any other contract or agreement or any restrictive covenant, and the continued employment of each such executive officer or other key employee (as the case may be) does not subject the Company or any of its Subsidiaries to any liability with respect
to any of the foregoing matters. The Company and its Subsidiaries are in compliance with all federal, state, local and foreign laws and regulations respecting labor, employment and employment practices and benefits, terms and conditions of
employment and wages and hours, except where failure to be in compliance would not, either individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect. 

  
 15 

 (w) Title. The Company and its Subsidiaries have good and marketable title in fee simple
to all real property and have good and marketable title to all personal property owned by them which is material to the business of the Company and its Subsidiaries, in each case, free and clear of all Liens except for Permitted Liens and such other
Liens as do not materially affect the value of such property and do not interfere with the use made and proposed to be made of such property by the Company and any of its Subsidiaries. Any real property and facilities held under lease by the Company
or any of its Subsidiaries are held by them under valid, subsisting and enforceable leases with such exceptions as are not material and do not interfere with the use made and proposed to be made of such property and buildings by the Company or any
of its Subsidiaries. 
 (x) Intellectual Property Rights. The Company and its Subsidiaries own or possess adequate rights or licenses
to use all trademarks, trade names, service marks, service mark registrations, service names, original works of authorship, patents, patent rights, copyrights, inventions, licenses, approvals, governmental authorizations, trade secrets and other
intellectual property rights and all applications and registrations therefor (“Intellectual Property Rights”) necessary to conduct their respective businesses as now conducted. Each of patents owned by the Company or any of its
Subsidiaries is listed on Schedule 3(x)(i). Except as set forth in Schedule 3(x)(ii), none of the Company’s Intellectual Property Rights have expired or terminated or have been abandoned or are expected to expire or terminate or are expected to
be abandoned, within three years from the date of this Agreement. The Company does not have any knowledge of any infringement by the Company or its Subsidiaries of Intellectual Property Rights of others. There is no claim, action or proceeding being
made or brought, or to the knowledge of the Company or any of its Subsidiaries, being threatened, against the Company or any of its Subsidiaries regarding its Intellectual Property Rights. Neither the Company nor any of its Subsidiaries is aware of
any facts or circumstances which might give rise to any of the foregoing infringements or claims, actions or proceedings. The Company and its Subsidiaries have taken reasonable security measures to protect the secrecy, confidentiality and value of
all of their Intellectual Property Rights 
 (y) Environmental Laws. The Company and its Subsidiaries (i) are in compliance with
any and all Environmental Laws (as defined below), (ii) have received all permits, licenses or other approvals required of them under applicable Environmental Laws to conduct their respective businesses and (iii) are in compliance with all
terms and conditions of any such permit, license or approval where, in each of the foregoing clauses (i), (ii) and (iii), the failure to so comply could be reasonably expected to have, individually or in the aggregate, a Material Adverse
Effect. The term “Environmental Laws” means all federal, state, local or foreign laws relating to pollution or protection of human health or the environment (including, without limitation, ambient air, surface water, groundwater,
land surface or subsurface strata), including, without limitation, laws relating to emissions, discharges, releases or threatened releases of chemicals, pollutants, contaminants, or toxic or hazardous substances or wastes (collectively,
“Hazardous Materials”) into the environment, or otherwise relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials, as well as all authorizations, codes,
decrees, demands or demand letters, injunctions, judgments, licenses, notices or notice letters, orders, permits, plans or regulations issued, entered, promulgated or approved thereunder.

all other tax returns, reports and declarations required by any jurisdiction to which it is subject, (ii) has timely paid all taxes and other governmental assessments and charges that are material in amount, shown or determined to be due on
such returns, reports and declarations, except those being contested in good faith and (iii) has set aside on its books provision reasonably adequate for the payment of all taxes for periods subsequent to the periods to which such returns,
reports or declarations apply. There are no unpaid taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company and its Subsidiaries know of no basis for any such claim. The Company is
not operated in such a manner as to qualify as a passive foreign investment company, as defined in Section 1297 of the Code. 
 (bb)
Internal Accounting and Disclosure Controls. The Company and each of its Subsidiaries maintains internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the 1934 Act) that is effective to provide reasonable
assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, including that (i) transactions are executed in accordance
with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset and liability accountability, (iii) access
to assets or incurrence of liabilities is permitted only in accordance with management’s general or specific authorization and (iv) the recorded accountability for assets and liabilities is compared with the existing assets and liabilities
at reasonable intervals and appropriate action is taken with respect to any difference. The Company maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the 1934 Act) that are effective in ensuring that
information required to be disclosed by the Company in the reports that it files or submits under the 1934 Act is recorded, processed, summarized and reported, within the time periods specified in the rules and forms of the SEC, including, without
limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the 1934 Act is accumulated and communicated to the Company’s management, including
its principal executive officer or officers and its principal financial officer or officers, as appropriate, to allow timely decisions regarding required disclosure. Neither the Company nor any of its Subsidiaries has received any notice or
correspondence from any accountant or other Person relating to any potential material weakness or significant deficiency in any part of the internal controls over financial reporting of the Company or any of its Subsidiaries. 

(cc) Off Balance Sheet Arrangements. There is no transaction, arrangement, or other relationship between the Company or any of its
Subsidiaries and an unconsolidated or other off balance sheet entity that is required to be disclosed by the Company in its 1934 Act filings and is not so disclosed or that otherwise could be reasonably likely to have a Material Adverse Effect. 

  
 17

the Securities will not be, an “investment company,” an affiliate of an “investment company,” a company controlled by an “investment company” or an “affiliated person” of, or “promoter” or

the public disclosure of the transactions contemplated by the Transaction Documents, in accordance with the terms thereof, none of the Buyers have been asked by the Company or any of its Subsidiaries to agree, nor has any Buyer agreed with the

with or control over any arm’s length counterparty in any “derivative” transaction. The Company further understands and acknowledges that following the public disclosure of the transactions contemplated by the Transaction Documents

value and/or number of the Warrant Shares or Conversion Shares, as applicable, deliverable with respect to the Securities are being determined and such hedging and/or trading activities, if any, can reduce the value of the existing
stockholders’ equity interest in the Company both at and after the time the hedging and/or trading activities are being conducted. The Company acknowledges that such aforementioned hedging and/or trading activities do not constitute a breach of
this Agreement, the Notes, the Warrants or any other Transaction Document or any of the documents executed in connection herewith or therewith. 

(ff) Manipulation of Price. Neither the Company nor any of its Subsidiaries has, and, to the knowledge of the Company, no Person acting

(qq) No Disqualification Events. With respect to Securities to be offered and sold hereunder in reliance on Rule 506(b) under the 1933
Act (“Regulation D Securities”), none of the Company, any of its predecessors, any affiliated issuer, any director, executive officer, other officer of the Company participating in the offering contemplated hereby, any beneficial
owner of 20% or more of the Company’s outstanding voting equity securities, calculated on the basis of voting power, nor any promoter (as that term is defined in Rule 405 under the 1933 Act) connected with the Company in any capacity at the
time of sale (each, an “Issuer Covered Person” and, together, “Issuer Covered Persons”) is subject to any of the “Bad Actor” disqualifications described in Rule 506(d)(1)(i) to (viii) under the 1933
Act (a “Disqualification Event”), except for a Disqualification Event covered by Rule 506(d)(2) or (d)(3). The Company has exercised reasonable care to determine whether any Issuer Covered Person is subject to a Disqualification

 (vv) Ranking of Notes. Except as set forth on Schedule 3(uu), no Indebtedness of the
Company, at the Closing, will be senior to, or pari passu with, the Notes in right of payment, whether with respect to payment or redemptions, interest, damages, upon liquidation or dissolution or otherwise. 

(ww) Disclosure. The Company confirms that neither it nor any other Person acting on its behalf has provided any of the Buyers or their
agents or counsel with any information that constitutes or could reasonably be expected to constitute material, non-public information concerning the Company or any of its Subsidiaries, other than the existence of the transactions contemplated by
this Agreement and the other Transaction Documents. The Company understands and confirms that each of the Buyers will rely on the foregoing representations in effecting transactions in securities of the Company. All disclosure provided to the Buyers
regarding the Company and its Subsidiaries, their businesses and the transactions contemplated hereby, including the schedules to this Agreement, furnished by or on behalf of the Company or any of its Subsidiaries is true and correct and does not
contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. All of the written information
furnished after the date hereof by or on behalf of the Company or any of its Subsidiaries to each Buyer pursuant to or in connection with this Agreement and the other Transaction Documents, taken as a whole, will be true and correct in all material
respects as of the date on which such information is so provided and will not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the
circumstances under which they were made, not misleading. No event or circumstance has occurred or information exists with respect to the Company or any of its Subsidiaries or its or their business, properties, liabilities, prospects, operations
(including results thereof) or conditions (financial or otherwise), which, under applicable law, rule or regulation, requires public disclosure at or before the date hereof or announcement by the Company but which has not been so publicly disclosed.
All financial projections and forecasts that have been prepared by or on behalf of the Company or any of its Subsidiaries and made available to you have been prepared in good faith based upon reasonable assumptions and represented, at the time each
such financial projection or forecast was delivered to each Buyer, the Company’s best estimate of future financial performance (it being recognized that such financial projections or forecasts are not to be viewed as facts and that the actual
results during the period or periods covered by any such financial projections or forecasts may differ from the projected or forecasted results). The Company acknowledges and agrees that no Buyer makes or has made any representations or warranties
with respect to the transactions contemplated hereby other than those specifically set forth in Section 2.

(h) Pledge of Securities. Notwithstanding anything to the contrary contained in this Agreement, the Company acknowledges and agrees
that the Securities may be pledged by an Investor in connection with a bona fide margin agreement or other loan or financing arrangement 

  
 24 

 
that is secured by the Securities. The pledge of Securities shall not be deemed to be a transfer, sale or assignment of the Securities hereunder, and no Investor effecting a pledge of Securities
shall be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other Transaction Document, including, without limitation, Section 2(f) hereof; provided
that an Investor and its pledgee shall be required to comply with the provisions of Section 2(f) hereof in order to effect a sale, transfer or assignment of Securities to such pledgee. The Company hereby agrees to execute and deliver such
documentation as a pledgee of the Securities may reasonably request in connection with a pledge of the Securities to such pledgee by a Buyer. 

(i) Disclosure of Transactions and Other Material Information. The Company shall, on or before 9:30 a.m., New York time, on the
first (1st) Business Day after the date of this Agreement, issue a press release (the “Press Release”) reasonably acceptable to the Buyers disclosing all the material terms
of the transactions contemplated by the Transaction Documents. On or before 9:30 a.m., New York time, on the first (1st) Business Day after the date of this Agreement, the Company shall file
a Current Report on Form 8-K describing all the material terms of the transactions contemplated by the Transaction Documents in the form required by the 1934 Act and attaching all the material Transaction Documents (including, without limitation,
this Agreement (and all schedules to this Agreement), the form of Notes, the form of Voting Agreement, the form of the Warrants, the form of Guaranties, the form of Collateral Agency Agreement, the form of Security Documents and the form of the
Registration Rights Agreement) (including all attachments, the “8-K Filing”). From and after the filing of the 8-K Filing, the Company shall have disclosed all material, non-public information (if any) provided to any of the Buyers
by the Company or any of its Subsidiaries or any of their respective officers, directors, employees or agents in connection with the transactions contemplated by the Transaction Documents. The Company shall not, and the Company shall cause each of
its Subsidiaries and each of its and their respective officers, directors, employees and agents not to, provide any Buyer with any material, non-public information regarding the Company or any of its Subsidiaries from and after the date hereof
without the express prior written consent of such Buyer (which may be granted or withheld in such Buyer’s sole discretion). In the event of a breach of any of the foregoing covenants, including, without limitation, Section 4(o) of this
Agreement, or any of the covenants or agreements contained in any other Transaction Document, by the Company, any of its Subsidiaries, or any of its or their respective officers, directors, employees and agents (as determined in the reasonable good
faith judgment of such Buyer), in addition to any other remedy provided herein or in the Transaction Documents, such Buyer shall have the right to make a public disclosure (after giving prior written notice to the Company), in the form of a press
release, public advertisement or otherwise, of such breach or such material, non-public information, as applicable, without the prior approval by the Company, any of its Subsidiaries, or any of its or their respective officers, directors, employees
or agents. No Buyer shall have any liability to the Company, any of its Subsidiaries, or any of its or their respective officers, directors, employees, stockholders or agents, for any such disclosure. To the extent that the Company delivers any
material, non-public information to a Buyer without such Buyer’s consent, the Company hereby covenants and agrees that such Buyer shall not have any duty of confidentiality with respect to, or a duty not to trade on the basis of, such material,
non-public information. Subject to the foregoing, neither the Company, its Subsidiaries nor any Buyer shall issue any press releases or any other public statements with respect to the transactions contemplated hereby; provided, however, the Company
shall be entitled, without the prior 

  
 25 

 
approval of any Buyer, to make the Press Release and any press release or other public disclosure with respect to such transactions (i) in substantial conformity with the 8-K Filing and
contemporaneously therewith and (ii) as is required by applicable law and regulations (provided that in the case of clause (i) each Buyer shall be consulted by the Company in connection with any such press release or other public
disclosure prior to its release). Without the prior written consent of the applicable Buyer (which may be granted or withheld in such Buyer’s sole discretion), the Company shall not (and shall cause each of its Subsidiaries and affiliates to
not) disclose the name of such Buyer in any filing, announcement, release or otherwise. Notwithstanding anything contained in this Agreement to the contrary and without implication that the contrary would otherwise be true, the Company expressly
acknowledges and agrees that no Buyer has had, and no Buyer shall have (unless expressly agreed to by a particular Buyer after the date hereof in a written definitive and binding agreement executed by the Company and such particular Buyer (it being
understood and agreed that no Buyer may bind any other Buyer with respect thereto)), any duty of confidentiality with respect to, or a duty not to trade on the basis of, any material, non-public information regarding the Company or any of its
Subsidiaries. 
 (j) Additional Registration Statements. Until the Applicable Date (as defined below) and at any time thereafter
while any Registration Statement is not effective or the prospectus contained therein is not available for use or any Current Public Information Failure (as defined in the Registration Rights Agreement) exists, the Company shall not file a
registration statement under the 1933 Act relating to securities that are not the Registrable Securities (other than a registration statement on Form S-8 or such supplements or amendments to registration statements that are outstanding and have been
declared effective by the SEC as of the date hereof (solely to the extent necessary to keep such registration statements effective and available and not with respect to any Subsequent Placement)). “Applicable Date” means the earlier
of (x) the first date on which the resale by the Buyers of all the Registrable Securities required to be filed on the initial Registration Statement (as defined in the Registration Rights Agreement) pursuant to the Registration Rights Agreement
is declared effective by the SEC (and each prospectus contained therein is available for use on such date) or (y) the first date on which all of the Registrable Securities are eligible to be resold by the Buyers pursuant to Rule 144 (or, if a
Current Public Information Failure (as defined in the Registration Rights Agreement) has occurred and is continuing, such later date after which the Company has cured such Current Public Information Failure). 

(k) Additional Issuance of Securities. So long as any Buyer beneficially owns any Securities, the Company will not, without the prior
written consent of the Required Holders, issue any Notes (other than to the Buyers as contemplated hereby) and the Company shall not issue any other securities that would cause a breach or default under the Notes or the Warrants. The Company agrees
that for the period commencing on the date hereof and ending on the date immediately following the 90th Trading Day after the Applicable Date (provided that such period shall be extended by the
number of calendar days during such period and any extension thereof contemplated by this proviso on which any Registration Statement is not effective or any prospectus contained therein is not available for use or any Current Public Information
Failure exists) (the “Restricted Period”), neither the Company nor any of its Subsidiaries shall directly or indirectly issue, offer, sell, grant any option or right to purchase, or otherwise dispose of (or announce any issuance,
offer, sale, grant of any option or right to purchase or other disposition of) any equity security or any equity-linked or related security (including, without limitation, any 

  
 26 

 
“equity security” (as that term is defined under Rule 405 promulgated under the 1933 Act), any Convertible Securities (as defined below), any debt, any preferred stock or any purchase
rights) (any such issuance, offer, sale, grant, disposition or announcement (whether occurring during the Restricted Period or at any time thereafter) is referred to as a “Subsequent Placement”). Notwithstanding the foregoing, this
Section 4(k) shall not apply in respect of the issuance of (i) shares of Common Stock or standard options to purchase Common Stock to directors, officers or employees of the Company in their capacity as such pursuant to an Approved Stock
Plan (as defined below), provided that (A) all such issuances (taking into account the shares of Common Stock issuable upon exercise of such options and restricted stock units) after the date hereof pursuant to this clause (i) together
with any issuance of Common Stock pursuant to clause (iv) below do not, in the aggregate, exceed more than 5% of the Common Stock issued and outstanding immediately prior to the date hereof and (B) the exercise price of any such options is
not lowered, none of such options are amended to increase the number of shares issuable thereunder and none of the terms or conditions of any such options are otherwise materially changed in any manner that adversely affects any of the Buyers;
(ii) shares of Common Stock issued upon the conversion or exercise of Convertible Securities (other than standard options to purchase Common Stock issued pursuant to an Approved Stock Plan that are covered by clause (i) above) issued prior
to the date hereof, provided that the conversion, exercise or other method of issuance (as the case may be) of any such Convertible Security is made solely pursuant to the conversion, exercise or other method of issuance (as the case may be)
provisions of such Convertible Security that were in effect on the date immediately prior to the date of this Agreement (including pursuant to all adjustment provisions of such Convertible Securities in effect prior to the date of this Agreement),
the conversion, exercise or issuance price of any such Convertible Securities (other than standard options to purchase Common Stock issued pursuant to an Approved Stock Plan that are covered by clause (i) above) is not lowered (other than
pursuant to adjustment provisions of such Convertible Securities in effect prior to the date of this Agreement), none of such Convertible Securities (other than standard options to purchase Common Stock issued pursuant to an Approved Stock Plan that
are covered by clause (i) above) are amended to increase the number of shares issuable thereunder and none of the terms or conditions of any such Convertible Securities (other than standard options to purchase Common Stock issued pursuant to an
Approved Stock Plan that are covered by clause (i) above) are otherwise materially changed in any manner that adversely affects any of the Buyers; (iii) shares of Common Stock or Convertible Securities issued or issuable pursuant to a bona
fide firm commitment underwritten public offering, in which all or part of the proceeds of which are used to redeem all Notes then outstanding in full; (iv) shares of Common Stock or Convertible Securities issued or issuable in connection with
strategic alliances, acquisitions, mergers, and strategic partnerships, provided, that (A) the primary purpose of such issuance is not to raise capital, (B) the purchasers or acquirers of the securities in such issuance does not include
any affiliate of the Company or any of its Subsidiaries and solely consists of either (x) the actual participants in such strategic alliance or strategic partnership, (y) the actual owners of such assets or securities acquired in such
acquisition or merger or (z) the stockholders, partners or members of the foregoing Persons, (C) the acquirers of such Common Stock and/or Convertible Securities, as applicable, in such offering enter into a six month lock-up agreement in
form and substance reasonably satisfactory to the Required Holders and (D) all such issuances (taking into account the shares of Common Stock issuable upon exercise of such options and restricted stock units) after the date hereof pursuant to
this clause (iv) together with any issuance of Common Stock 

  
 27 

 
pursuant to clause (i) above do not, in the aggregate, exceed more than 5% of the Common Stock issued and outstanding immediately prior to the date hereof, (v) the Conversion Shares,
and (vi) the Warrant Shares (each of the foregoing in clauses (i) through (vi), collectively the “Excluded Securities”). “Approved Stock Plan” means any employee benefit plan or agreement which has been
approved by the board of directors of the Company prior to or subsequent to the date hereof pursuant to which shares of Common Stock and standard options to purchase Common Stock may be issued to any employee, officer, consultant or director for
services provided to the Company in their capacity as such. “Convertible Securities” means any capital stock or other security of the Company or any of its Subsidiaries that is at any time and under any circumstances directly or
indirectly convertible into, exercisable or exchangeable for, or which otherwise entitles the holder thereof to acquire, any capital stock or other security of the Company (including, without limitation, Common Stock) or any of its Subsidiaries.

 (l) Reservation of Shares. So long as any of the Notes or Warrants remain outstanding, the Company shall take all action necessary
to at all times have authorized, and reserved for the purpose of issuance, no less than (A) if prior to the Stock Split Stockholder Approval Date (as defined below) 100 million shares of Common Stock issuable upon conversion of the Notes
or (B) if on or after the Stock Split Stockholder Approval Date, 150% of (i) the maximum number of shares of Common Stock issuable upon conversion of all the Notes then outstanding (assuming for purposes hereof that (x) the Notes are
convertible at the Conversion Price (then in effect, (y) interest on the Notes shall accrue through the sixty month anniversary of the Closing Date and will be converted in shares of Common Stock at an interest conversion price equal to the
Interest Conversion Price assuming an Interest Date as of the applicable date of determination and (z) any such conversion shall not take into account any limitations on the conversion of the Notes set forth in the Notes), and (ii) the
maximum number of Warrant Shares issuable upon exercise of all the Warrants then outstanding (without regard to any limitations on the exercise of the Warrants set forth therein) (collectively, the “Required Reserve Amount”). If at
any time the number of shares of Common Stock authorized and reserved for issuance is not sufficient to meet the Required Reserved Amount, the Company will promptly take all corporate action necessary to authorize and reserve a sufficient number of
shares, including, without limitation, calling a special meeting of stockholders to authorize additional shares to meet the Company’s obligations pursuant to the Transaction Documents, in the case of an insufficient number of authorized shares,
obtain stockholder approval of an increase in such authorized number of shares, and voting the management shares of the Company in favor of an increase in the authorized shares of the Company to ensure that the number of authorized shares is
sufficient to meet the Required Reserved Amount. 
 (m) Conduct of Business. The business of the Company and its Subsidiaries shall
not be conducted in violation of any law, ordinance or regulation of any Governmental Entity, except where such violations would not reasonably be expected to result, either individually or in the aggregate, in a Material Adverse Effect. 

(n) Other Notes; Variable Securities. So long as any Notes remain outstanding, the Company and each Subsidiary shall be prohibited from
effecting or entering into an agreement to effect any Subsequent Placement involving a Variable Rate Transaction. “Variable Rate Transaction” means a transaction in which the Company or any Subsidiary (i) issues or sells any
Convertible Securities either (A) at a conversion, exercise or exchange rate or other price 

  
 28 

 
that is based upon and/or varies with the trading prices of or quotations for the shares of Common Stock at any time after the initial issuance of such Convertible Securities, or (B) with a
conversion, exercise or exchange price that is subject to being reset at some future date after the initial issuance of such Convertible Securities or upon the occurrence of specified or contingent events directly or indirectly related to the
business of the Company or the market for the Common Stock, other than pursuant to a customary “weighted average” anti-dilution provision or (ii) enters into any agreement (including, without limitation, an equity line of credit or an
“at-the-market” offering) whereby the Company or any Subsidiary may sell securities at a future determined price (other than standard and customary “preemptive” or “participation” rights). Each Buyer shall be entitled
to obtain injunctive relief against the Company and its Subsidiaries to preclude any such issuance, which remedy shall be in addition to any right to collect damages. 

(o) Participation Right. So long as any Notes remain outstanding, neither the Company nor any of its Subsidiaries shall, directly or
indirectly, effect any Subsequent Placement unless the Company shall have first complied with this Section 4(o). The Company acknowledges and agrees that the right set forth in this Section 4(o) is a right granted by the Company,
separately, to each Buyer. 
 (i) At least five (5) Trading Days prior to any proposed or intended Subsequent Placement,
the Company shall deliver to each Buyer a written notice (each such notice, a “Pre-Notice”), which Pre-Notice shall not contain any information (including, without limitation, material, non-public information) other than:
(i) if the proposed Offer Notice (as defined below) constitutes or contains material, non-public information, a statement asking whether the Investor is willing to accept material non-public information or (ii) if the proposed Offer Notice
does not constitute or contain material, non-public information, (A) a statement that the Company proposes or intends to effect a Subsequent Placement, (B) a statement that the statement in clause (A) above does not constitute
material, non-public information and (C) a statement informing such Buyer that it is entitled to receive an Offer Notice (as defined below) with respect to such Subsequent Placement upon its written request. Upon the written request of a Buyer
within three (3) Trading Days after the Company’s delivery to such Buyer of such Pre-Notice, and only upon a written request by such Buyer, the Company shall promptly, but no later than one (1) Trading Day after such request, deliver
to such Buyer an irrevocable written notice (the “Offer Notice”) of any proposed or intended issuance or sale or exchange (the “Offer”) of the securities being offered (the “Offered Securities”) in
a Subsequent Placement, which Offer Notice shall (w) identify and describe the Offered Securities, (x) describe the price and other terms upon which they are to be issued, sold or exchanged, and the number or amount of the Offered
Securities to be issued, sold or exchanged, (y) identify the Persons (if known) to which or with which the Offered Securities are to be offered, issued, sold or exchanged and (z) offer to issue and sell to or exchange with such Buyer in
accordance with the terms of the Offer such Buyer’s pro rata portion of 50% of the Offered Securities, provided that the number of Offered Securities which such Buyer shall have the right to subscribe for under this Section 4(o) shall be
(a) based on such Buyer’s pro rata portion of the aggregate original principal amount of the Notes purchased hereunder by all Buyers (the “Basic Amount”), and (b) with respect to each Buyer that elects to purchase its
Basic Amount, any additional portion of the Offered Securities attributable to the Basic Amounts of other Buyers as such Buyer shall indicate it will purchase or acquire should the other Buyers subscribe for less than their Basic Amounts (the
“Undersubscription Amount”). 

  
 29 

 (ii) To accept an Offer, in whole or in part, such Buyer must deliver a written
notice to the Company prior to the end of the third (3rd) Business Day after such Buyer’s receipt of the Offer Notice (the “Offer Period”), setting forth the portion of
such Buyer’s Basic Amount that such Buyer elects to purchase and, if such Buyer shall elect to purchase all of its Basic Amount, the Undersubscription Amount, if any, that such Buyer elects to purchase (in either case, the “Notice of
Acceptance”). If the Basic Amounts subscribed for by all Buyers are less than the total of all of the Basic Amounts, then such Buyer who has set forth an Undersubscription Amount in its Notice of Acceptance shall be entitled to purchase, in
addition to the Basic Amounts subscribed for, the Undersubscription Amount it has subscribed for; provided, however, if the Undersubscription Amounts subscribed for exceed the difference between the total of all the Basic Amounts and the Basic
Amounts subscribed for (the “Available Undersubscription Amount”), such Buyer who has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription Amount as the Basic
Amount of such Buyer bears to the total Basic Amounts of all Buyers that have subscribed for Undersubscription Amounts, subject to rounding by the Company to the extent it deems reasonably necessary. Notwithstanding the foregoing, if the Company
desires to modify or amend the terms and conditions of the Offer prior to the expiration of the Offer Period, the Company may deliver to each Buyer a new Offer Notice and the Offer Period shall expire on the third (3rd) Business Day after such Buyer’s receipt of such new Offer Notice. 

(iii) The Company shall have five (5) Business Days from the expiration of the Offer Period above (i) to offer,
issue, sell or exchange all or any part of such Offered Securities as to which a Notice of Acceptance has not been given by a Buyer (the “Refused Securities”) pursuant to a definitive agreement(s) (the “Subsequent Placement
Agreement”), but only to the offerees described in the Offer Notice (if so described therein) and only upon terms and conditions (including, without limitation, unit prices and interest rates) that are not more favorable to the acquiring
Person or Persons or less favorable to the Company than those set forth in the Offer Notice and (ii) to publicly announce (a) the execution of such Subsequent Placement Agreement, and (b) either (x) the consummation of the
transactions contemplated by such Subsequent Placement Agreement or (y) the termination of such Subsequent Placement Agreement, which shall be filed with the SEC on a Current Report on Form 8-K with such Subsequent Placement Agreement and any
documents contemplated therein filed as exhibits thereto. 
 (iv) In the event the Company shall propose to sell less than
all the Refused Securities (any such sale to be in the manner and on the terms specified in Section 4(o)(iii) above), then such Buyer may, at its sole option and in its sole discretion, reduce the number or amount of the Offered Securities
specified in its Notice of Acceptance to an amount that shall be not less than the number or amount of the Offered Securities that such Buyer elected to purchase pursuant to Section 4(o)(ii) above multiplied by a fraction, (i) the
numerator of which shall be the number or amount of Offered Securities the Company actually proposes to issue, sell or exchange (including 

  
 30 

 
Offered Securities to be issued or sold to Buyers pursuant to this Section 4(o) prior to such reduction) and (ii) the denominator of which shall be the original amount of the Offered
Securities. In the event that any Buyer so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company may not issue, sell or exchange more than the reduced number or amount of the Offered
Securities unless and until such securities have again been offered to the Buyers in accordance with Section 4(o)(i) above. 

(v) Upon the closing of the issuance, sale or exchange of all or less than all of the Refused Securities, such Buyer shall
acquire from the Company, and the Company shall issue to such Buyer, the number or amount of Offered Securities specified in its Notice of Acceptance. The purchase by such Buyer of any Offered Securities is subject in all cases to the preparation,
execution and delivery by the Company and such Buyer of a separate purchase agreement relating to such Offered Securities reasonably satisfactory in form and substance to such Buyer and its counsel. 

(vi) Any Offered Securities not acquired by a Buyer or other Persons in accordance with this Section 4(o) may not be
issued, sold or exchanged until they are again offered to such Buyer under the procedures specified in this Agreement. 

(vii) The Company and each Buyer agree that if any Buyer elects to participate in the Offer, neither the Subsequent Placement
Agreement with respect to such Offer nor any other transaction documents related thereto (collectively, the “Subsequent Placement Documents”) shall include any term or provision whereby such Buyer shall be required to agree to any
restrictions on trading as to any securities of the Company or be required to consent to any amendment to or termination of, or grant any waiver, release or the like under or in connection with, any agreement previously entered into with the Company
or any instrument received from the Company. 
 (viii) Notwithstanding anything to the contrary in this Section 4(o) and
unless otherwise agreed to by such Buyer, the Company shall either confirm in writing to such Buyer that the transaction with respect to the Subsequent Placement has been abandoned or shall publicly disclose its intention to issue the Offered
Securities, in either case, in such a manner such that such Buyer will not be in possession of any material, non-public information, by the fifth (5th) Business Day following delivery of the
Offer Notice. If by such fifth (5th) Business Day, no public disclosure regarding a transaction with respect to the Offered Securities has been made, and no notice regarding the abandonment
of such transaction has been received by such Buyer, such transaction shall be deemed to have been abandoned and such Buyer shall not be in possession of any material, non-public information with respect to the Company or any of its Subsidiaries.
Should the Company decide to pursue such transaction with respect to the Offered Securities, the Company shall provide such Buyer with another Offer Notice and such Buyer will again have the right of participation set forth in this
Section 4(o). The Company shall not be permitted to deliver more than one such Offer Notice to such Buyer in any sixty (60) day period, except as expressly contemplated by the last sentence of Section 4(o)(ii). 

(ix) The restrictions contained in this Section 4(o) shall not apply in connection with the issuance of any Excluded
Securities. The Company shall not circumvent the provisions of this Section 4(o) by providing terms or conditions to one Buyer that are not provided to all.

 (p) Dilutive Issuances. For so long as any Notes or Warrants remain outstanding, the
Company shall not, in any manner, enter into or affect any Dilutive Issuance (as defined in the Notes) if the effect of such Dilutive Issuance is to cause the Company to be required to issue upon conversion of any Notes or exercise of any Warrant
any shares of Common Stock in excess of that number of shares of Common Stock which the Company may issue upon conversion of the Notes and exercise of the Warrants without breaching the Company’s obligations under the rules or regulations of

announcement or disclosure with respect to any of the foregoing) without the prior written consent of the Required Holders (as defined below). 

(u) Conversion and Exercise Procedures. Each of the form of Notice of Exercise included in the Warrants and the form of Notice of

instructions shall be required of the Buyers to exercise their Warrants or convert their Notes. The Company shall honor exercises of the Warrants and conversions of the Notes and shall deliver the Conversion Shares and Warrant Shares in accordance

in respect of any security (as defined in the 1933 Act) which will be integrated with the sale of the Securities in a manner which would require the registration of the Securities under the 1933 Act or require stockholder approval under the rules
and regulations of the Principal Market and the Company will take all action that is appropriate or necessary to assure that its offerings of other securities will not be integrated for purposes of the 1933 Act or the rules and regulations of the

	5.	REGISTER; TRANSFER AGENT INSTRUCTIONS; LEGEND. 

 (a) Register. The Company shall
maintain at its principal executive offices (or such other office or agency of the Company as it may designate by notice to each holder of Securities), a register for the Notes and the Warrants in which the Company shall record the name and address
of the Person in whose name the Notes and the Warrants have been issued (including the name and address of each transferee), the principal amount of the Notes held by such Person, the number of Conversion Shares issuable upon conversion of the Notes
and the number of Warrant Shares issuable upon exercise of the Warrants held by such Person. The Company shall keep the register open and available at all times during business hours for inspection of any Buyer or its legal representatives. 

(b) Transfer Agent Instructions. The Company shall issue irrevocable instructions to its transfer agent and any subsequent transfer
agent in a form acceptable to each of the Buyers (the “Irrevocable Transfer Agent Instructions”) to issue certificates or credit shares to the applicable balance accounts at The Depository Trust Company (“DTC”),
registered in the name of each Buyer or its respective nominee(s), for the Conversion Shares and the Warrant Shares in such amounts as specified from time to time by each Buyer to the Company upon conversion of the Notes or the exercise of the
Warrants (as the case may be). The Company represents and warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 5(b), and stop transfer instructions to give effect to Section 2(g)
hereof, will be given by the Company to its transfer agent with respect to the Securities, and that the Securities shall otherwise be freely transferable on the books and records of the Company, as applicable, to the extent provided in this
Agreement and the other Transaction Documents. If a Buyer effects a sale, assignment or transfer of the Securities in accordance with Section 2(g), the Company shall permit the transfer and shall promptly instruct its transfer agent to issue
one or more certificates 

  
 34 

 
or credit shares to the applicable balance accounts at DTC in such name and in such denominations as specified by such Buyer to effect such sale, transfer or assignment. In the event that such
sale, assignment or transfer involves Conversion Shares or Warrant Shares sold, assigned or transferred pursuant to an effective registration statement or in compliance with Rule 144, the transfer agent shall issue such shares to such Buyer,
assignee or transferee (as the case may be) without any restrictive legend in accordance with Section 5(d) below. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to a Buyer. Accordingly, the
Company acknowledges that the remedy at law for a breach of its obligations under this Section 5(b) will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 5(b), that a
Buyer shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other
security being required. The Company shall cause its counsel to issue the legal opinion referred to in the Irrevocable Transfer Agent Instructions to the Company’s transfer agent on each Effective Date (as defined in the Registration Rights
Agreement). Any fees (with respect to the transfer agent, counsel to the Company or otherwise) associated with the issuance of such opinion or the removal of any legends on any of the Securities shall be borne by the Company. 

(c) Legends. Each Buyer understands that the Securities have been issued (or will be issued in the case of the Conversion Shares and
the Warrant Shares) pursuant to an exemption from registration or qualification under the 1933 Act and applicable state securities laws, and except as set forth below, the Securities shall bear any legend as required by the “blue sky” laws
of any state and a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of such stock certificates): 

[NEITHER THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE
[CONVERTIBLE] [EXERCISABLE] HAVE BEEN][THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN] REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD,
TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL TO THE HOLDER (IF REQUESTED BY THE COMPANY), IN A FORM
REASONABLY ACCEPTABLE TO THE COMPANY, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD OR ELIGIBLE TO BE SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN
CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES. 
 (d) Removal of
Legends. Certificates evidencing Securities shall not be required to contain the legend set forth in Section 5(c) above or any other legend (i) while a registration 

  
 35 

 
statement (including a Registration Statement) covering the resale of such Securities is effective under the 1933 Act, (ii) following any sale of such Securities pursuant to Rule 144
(assuming the transferor is not an affiliate of the Company), (iii) if such Securities are eligible to be sold, assigned or transferred under Rule 144 (provided that a Buyer provides the Company with reasonable assurances that such Securities
are eligible for sale, assignment or transfer under Rule 144 which shall not include an opinion of Buyer’s counsel), (iv) in connection with a sale, assignment or other transfer (other than under Rule 144), provided that such Buyer
provides the Company with an opinion of counsel to such Buyer, in a generally acceptable form, to the effect that such sale, assignment or transfer of the Securities may be made without registration under the applicable requirements of the 1933 Act
or (v) if such legend is not required under applicable requirements of the 1933 Act (including, without limitation, controlling judicial interpretations and pronouncements issued by the SEC). If a legend is not required pursuant to the
foregoing, the Company shall no later than three (3) Trading Days (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 date such Buyer delivers
such legended certificate representing such Securities to the Company) following the delivery by a Buyer to the Company or the transfer agent (with notice to the Company) of a legended certificate representing such Securities (endorsed or with stock
powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance and/or transfer, if applicable), together with any other deliveries from such Buyer as may be required above in this Section 5(d), as directed by
such Buyer, either: (A) provided that the Company’s transfer agent is participating in the DTC Fast Automated Securities Transfer Program and such Securities are Conversion Shares or Warrant Shares, credit the aggregate number of shares of
Common Stock to which such Buyer shall be entitled to such Buyer’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system or (B) if the Company’s transfer agent is not participating in the
DTC Fast Automated Securities Transfer Program, issue and deliver (via reputable overnight courier) to such Buyer, a certificate representing such Securities that is free from all restrictive and other legends, registered in the name of such Buyer
or its designee (the date by which such credit is so required to be made to the balance account of such Buyer’s or such Buyer’s nominee with DTC or such certificate is required to be delivered to such Buyer pursuant to the foregoing is
referred to herein as the “Required Delivery Date”). The Company shall be responsible for any transfer agent fees or DTC fees with respect to any issuance of Securities or the removal of any legends with respect to any Securities in
accordance herewith. 
 (e) Failure to Timely Deliver; Buy-In. If the Company fails to (i) issue and deliver (or cause to be
delivered) to a Buyer by the Required Delivery Date a certificate representing the Securities so delivered to the Company by such Buyer that is free from all restrictive and other legends or (ii) credit the balance account of such Buyer’s
or such Buyer’s nominee with DTC for such number of Conversion Shares or Warrant Shares so delivered to the Company, then, in addition to all other remedies available to such Buyer, the Company shall pay in cash to such Buyer on each day after
the Required Delivery Date and if on or after the Required Delivery Date such Buyer purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by such Buyer 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 that such Buyer anticipated receiving from the Company without any restrictive legend, then, in addition
to all other remedies available to such Buyer, the Company shall, within three (3) Trading Days after such Buyer’s request and in such 

  
 36 

 
Buyer’s sole discretion, either (i) pay cash to such Buyer in an amount equal to such Buyer’s total purchase price (including brokerage commissions and other out-of-pocket
expenses, if any) for the shares of Common Stock so purchased (including brokerage commissions and other out-of-pocket expenses, if any) (the “Buy-In Price”), at which point the Company’s obligation to so deliver such
certificate or credit such Buyer’s balance account shall terminate and such shares shall be cancelled, or (ii) promptly honor its obligation to so deliver to such Buyer a certificate or certificates or credit such Buyer’s DTC account
representing such number of shares of Common Stock that would have been so delivered if the Company timely complied with its obligations hereunder and pay cash to such Buyer in an amount equal to the excess (if any) of the Buy-In Price over the
product of (A) such number of shares of Conversion Shares or Warrant Shares (as the case may be) that the Company was required to deliver to such Buyer by the Required Delivery Date multiplied by (B) the lowest Closing Sale Price (as
defined in the Warrants) of the Common Stock on any Trading Day during the period commencing on the date of the delivery by such Buyer to the Company of the applicable Conversion Shares or Warrant Shares (as the case may be) and ending on the date
of such delivery and payment under this clause (ii).

hereunder or in connection herewith or under any of the other Transaction Documents or with any transaction contemplated hereby or thereby, 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. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it under this Agreement
and agrees that such service shall constitute good and sufficient service of process and notice thereof. 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 any Buyer from bringing suit or taking other legal action against the Company in any other jurisdiction to collect on the Company’s obligations to such Buyer or to enforce a judgment or other court ruling
in favor of such Buyer. EACH PARTY 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 UNDER ANY OTHER TRANSACTION DOCUMENT OR IN CONNECTION WITH OR ARISING
OUT OF THIS AGREEMENT, ANY OTHER TRANSACTION DOCUMENT OR ANY TRANSACTION CONTEMPLATED HEREBY OR THEREBY. 
 (b) Counterparts.
This Agreement may be executed in two or more identical counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party. In the
event that any signature is delivered by facsimile transmission or by an e-mail which contains a portable document format (.pdf) file of an executed signature page, such signature page shall create a valid and binding obligation of the party
executing (or on whose behalf such signature is executed) with the same force and effect as if such signature page were an original thereof. 

(c) Headings; Gender. The headings of this Agreement are for convenience of reference and shall not form part of, or affect the
interpretation of, this Agreement. Unless the context clearly indicates otherwise, each pronoun herein shall be deemed to include the masculine, feminine, neuter, singular and plural forms thereof. The terms “including,”
“includes,” “include” and words of like import shall be construed broadly as if followed by the words “without limitation.” The terms “herein,” “hereunder,” “hereof” and words of like
import refer to this entire Agreement instead of just the provision in which they are found. 
 (d) Severability; Maximum Payment
Amounts. If any provision of this Agreement 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 Agreement so long as this Agreement 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 

  
 42 

 
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). Notwithstanding anything to
the contrary contained in this Agreement or any other Transaction Document (and without implication that the following is required or applicable), it is the intention of the parties that in no event shall amounts and value paid by the Company and/or
any of its Subsidiaries (as the case may be), or payable to or received by any of the Buyers, under the Transaction Documents (including without limitation, any amounts that would be characterized as “interest” under applicable law) exceed
amounts permitted under any applicable law. Accordingly, if any obligation to pay, payment made to any Buyer, or collection by any Buyer pursuant the Transaction Documents is finally judicially determined to be contrary to any such applicable law,
such obligation to pay, payment or collection shall be deemed to have been made by mutual mistake of such Buyer, the Company and its Subsidiaries and such amount shall be deemed to have been adjusted with retroactive effect to the maximum amount or
rate of interest, as the case may be, as would not be so prohibited by the applicable law. Such adjustment shall be effected, to the extent necessary, by reducing or refunding, at the option of such Buyer, the amount of interest or any other amounts
which would constitute unlawful amounts required to be paid or actually paid to such Buyer under the Transaction Documents. For greater certainty, to the extent that any interest, charges, fees, expenses or other amounts required to be paid to or
received by such Buyer under any of the Transaction Documents or related thereto are held to be within the meaning of “interest” or another applicable term to otherwise be violative of applicable law, such amounts shall be pro-rated over
the period of time to which they relate. 
 (e) Entire Agreement; Amendments. This Agreement, the other Transaction Documents and the
schedules and exhibits attached hereto and thereto and the instruments referenced herein and therein supersede all other prior oral or written agreements between the Buyers, the Company, its Subsidiaries, their affiliates and Persons acting on their
behalf, including, without limitation, any transactions by any Buyer with respect to Common Stock or the Securities, and the other matters contained herein and therein, and this Agreement, the other Transaction Documents, the schedules and exhibits
attached hereto and thereto and the instruments referenced herein and therein contain the entire understanding of the parties solely with respect to the matters covered herein and therein; provided, however, nothing contained in this Agreement or
any other Transaction Document shall (or shall be deemed to) (i) have any effect on any agreements any Buyer has entered into with, or any instruments any Buyer has received from, the Company or any of its Subsidiaries prior to the date hereof
with respect to any prior investment made by such Buyer in the Company or (ii) waive, alter, modify or amend in any respect any obligations of the Company or any of its Subsidiaries, or any rights of or benefits to any Buyer or any other
Person, in any agreement entered into prior to the date hereof between or among the Company and/or any of its Subsidiaries and any Buyer, or any instruments any Buyer received from the Company and/or any of its Subsidiaries prior to the date hereof,
and all such agreements and instruments shall continue in full force and effect. Except as specifically set forth herein or therein, neither the Company nor any Buyer makes any representation, warranty, covenant or undertaking with respect to such
matters. For clarification purposes, the Recitals are part of this Agreement. No provision of this Agreement may be amended other than by an instrument in writing signed by the Company and the Required Holders (as defined below), and any amendment
to any provision of this Agreement made in conformity with the provisions of this Section 9(e) shall be binding on all Buyers and holders of Securities, as applicable, provided that no such amendment shall be effective to the extent that it
(A) applies to less than all of the 

  
 43 

 
holders of the Securities then outstanding or (B) imposes any obligation or liability on any Buyer without such Buyer’s prior written consent (which may be granted or withheld in such
Buyer’s sole discretion). No waiver shall be effective unless it is in writing and signed by an authorized representative of the waiving party, provided that the Required Holders may waive any provision of this Agreement, and any waiver of any
provision of this Agreement made in conformity with the provisions of this Section 9(e) shall be binding on all Buyers and holders of Securities, as applicable, provided that no such waiver shall be effective to the extent that it
(1) applies to less than all of the holders of the Securities then outstanding (unless a party gives a waiver as to itself only) or (2) imposes any obligation or liability on any Buyer without such Buyer’s prior written consent (which
may be granted or withheld in such Buyer’s sole discretion). No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless the same
consideration also is offered to all of the parties to the Transaction Documents, all holders of the Notes or all holders of the Warrants (as the case may be) (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 entitled to any consideration granted to any other holder of Notes in connection with any amendment, consent, waiver or modification related to any provision relating to any Master Control Account). The
Company has not, directly or indirectly, made any agreements with any Buyers relating to the terms or conditions of the transactions contemplated by the Transaction Documents except as set forth in the Transaction Documents. Without limiting the
foregoing, the Company confirms that, except as set forth in this Agreement, no Buyer has made any commitment or promise or has any other obligation to provide any financing to the Company, any Subsidiary or otherwise. As a material inducement for
each Buyer to enter into this Agreement, the Company expressly acknowledges and agrees that (x) no due diligence or other investigation or inquiry conducted by a Buyer, any of its advisors or any of its representatives shall affect such
Buyer’s right to rely on, or shall modify or qualify in any manner or be an exception to any of, the Company’s representations and warranties contained in this Agreement or any other Transaction Document and (y) unless a provision of
this Agreement or any other Transaction Document is expressly preceded by the phrase “except as disclosed in the SEC Documents,” nothing contained in any of the SEC Documents shall affect such Buyer’s right to rely on, or shall modify
or qualify in any manner or be an exception to any of, the Company’s representations and warranties contained in this Agreement or any other Transaction Document. “Required Holders” means (I) prior to the Closing Date,
Buyers entitled to purchase, in the aggregate, at least 65% of the Notes at the Closing and (II) on or after the Closing Date, holders of, in the aggregate, at least 65% of the Registrable Securities as of such time (excluding any Registrable
Securities held by the Company or any of its Subsidiaries as of such time) issued or issuable hereunder or pursuant to the Notes and/or the Warrants (or Buyers that purchased, in the aggregate, at least 65% of the Notes hereunder, with respect to
any waiver or amendment of Section 4(o)). 
 (f) Notices. Any notices, consents, waivers or other communications required or
permitted to be given under the terms of this Agreement must be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by facsimile (provided confirmation of
transmission is mechanically or electronically generated and kept on file by the sending party); or (iii) one (1) Business Day after deposit with an overnight courier service with next day delivery specified, in each case, properly

 (g) Successors and Assigns. This Agreement shall be binding upon and inure to the benefit
of the parties and their respective successors and assigns, including any purchasers of any of the Notes and Warrants. The Company shall not assign this Agreement or any rights or obligations hereunder without the prior written consent of the
Required Holders, including, without limitation, by way of a Fundamental Transaction (as defined in the Warrants) (unless the Company is in compliance with the applicable provisions governing Fundamental Transactions set forth in the Warrants) or a
Fundamental Transaction (as defined in the Notes) (unless the Company is in compliance with the applicable provisions governing Fundamental Transactions set forth in the Notes). A Buyer may assign some or all of its rights hereunder in connection
with any transfer of any of its Securities without the consent of the Company, in which event such assignee shall be deemed to be a Buyer hereunder with respect to such assigned rights. 

(h) No Third Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective permitted
successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, other than the Indemnitees referred to in Section 9(k). 

(i) Survival. The representations, warranties, agreements and covenants shall survive the Closing. Each Buyer shall be responsible only
for its own representations, warranties, agreements and covenants hereunder. 
 (j) Further Assurances. Each party shall do and
perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as any other party may reasonably request in order to carry out the
intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby. 
 (k)
Indemnification. In consideration of each Buyer’s execution and delivery of the Transaction Documents and acquiring the Securities thereunder and in addition to all of the Company’s other obligations under the Transaction Documents,
the Company shall defend, protect, indemnify and hold harmless each Buyer and each holder of any Securities and all of their stockholders, partners, members, officers, directors, employees and direct or indirect investors and any of the foregoing
Persons’ agents or other representatives (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”) from and against any and all actions,
causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and
including reasonable attorneys’ fees and disbursements (the “Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to (i) any misrepresentation or breach of any representation
or warranty made by the Company or any Subsidiary in any of the Transaction Documents, (ii) any breach of any covenant, agreement or obligation of the Company or any Subsidiary contained in any of the Transaction Documents or (iii) any
cause of action, suit, proceeding or claim brought or made against such Indemnitee by a third party (including for these purposes a derivative action brought 

  
 46 

 
on behalf of the Company or any Subsidiary) or which otherwise involves such Indemnitee that arises out of or results from (A) the execution, delivery, performance or enforcement of any of
the Transaction Documents, (B) any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of the issuance of the Securities, (C) any disclosure properly made by such Buyer pursuant to
Section 4(i), or (D) the status of such Buyer or holder of the Securities either as an investor in the Company pursuant to the transactions contemplated by the Transaction Documents or as a party to this Agreement (including, without
limitation, as a party in interest or otherwise in any action or proceeding for injunctive or other equitable relief). To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the
maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. Except as otherwise set forth herein, the mechanics and procedures with respect to the rights and obligations
under this Section 9(k) shall be the same as those set forth in Section 6 of the Registration Rights Agreement. 
 (l)
Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party. No specific representation or
warranty shall limit the generality or applicability of a more general representation or warranty. Each and every reference to share prices, shares of Common Stock and any other numbers in this Agreement that relate to the Common Stock shall be
automatically adjusted for any stock splits, stock dividends, stock combinations, recapitalizations or other similar transactions that occur with respect to the Common Stock after the date of this Agreement. It is expressly understood and agreed
that for all purposes of this Agreement, and without implication that the contrary would otherwise be true, neither transactions nor purchases nor sales shall include the location and/or reservation of borrowable shares of Common Stock. 

(m) Remedies. Each Buyer and in the event of assignment by Buyer of its rights and obligations hereunder, each holder of Securities,
shall have all rights and remedies set forth in the Transaction Documents and all rights and remedies which such holders have been granted at any time under any other agreement or contract and all of the rights which such holders have under any law.
Any Person having any rights under any provision of this Agreement shall be entitled to enforce such rights specifically (without posting a bond or other security), to recover damages by reason of any breach of any provision of this Agreement and to
exercise all other rights granted by law. Furthermore, the Company recognizes that in the event that it or any Subsidiary fails to perform, observe, or discharge any or all of its or such Subsidiary’s (as the case may be) obligations under the
Transaction Documents, any remedy at law may prove to be inadequate relief to the Buyers. The Company therefore agrees that the Buyers shall be entitled to seek specific performance and/or temporary, preliminary and permanent injunctive or other
equitable relief from any court of competent jurisdiction in any such case without the necessity of proving actual damages and without posting a bond or other security. The remedies provided in this Agreement and the other Transaction Documents
shall be cumulative and in addition to all other remedies available under this Agreement and the other Transaction Documents, at law or in equity (including a decree of specific performance and/or other injunctive relief). 

(n) Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the
Transaction Documents, whenever any Buyer 

  
 47 

 
exercises a right, election, demand or option under a Transaction Document and the Company or any Subsidiary does not timely perform its related obligations within the periods therein provided,
then such Buyer may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company or such Subsidiary (as the case may be), any relevant notice, demand or election in whole or in part without prejudice to its future
actions and rights. 
 (o) Payment Set Aside; Currency. To the extent that the Company makes a payment or payments to any Buyer
hereunder or pursuant to any of the other Transaction Documents or any of the Buyers enforce or exercise their rights hereunder or thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are
subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person under any law
(including, without limitation, any bankruptcy law, foreign, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be
revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred. Unless otherwise expressly indicated, all dollar amounts referred to in this Agreement and the other Transaction
Documents are in United States Dollars (“U.S. Dollars”), and all amounts owing under this Agreement and all other Transaction Documents shall be paid in U.S. Dollars. All amounts denominated in other currencies (if any) shall be
converted into the U.S. Dollar equivalent amount in accordance with the Exchange Rate on the date of calculation. “Exchange Rate” means, in relation to any amount of currency to be converted into U.S. Dollars pursuant to this
Agreement, the U.S. Dollar exchange rate as published in the Wall Street Journal on the relevant date of calculation. 
 (p)
Judgment Currency. 
 (i) If for the purpose of obtaining or enforcing judgment against the Company in connection with
this Agreement or any other Transaction Document in any court in any jurisdiction it becomes necessary to convert into any other currency (such other currency being hereinafter in this Section 9(p) referred to as the “Judgment
Currency”) an amount due in US Dollars under this Agreement, the conversion shall be made at the Exchange Rate prevailing on the Trading Day immediately preceding: 

(1) the date actual payment of the amount due, in the case of any proceeding in the courts of New York or in the courts of any
other jurisdiction that will give effect to such conversion being made on such date: or 
 (2) the date on which the foreign
court determines, in the case of any proceeding in the courts of any other jurisdiction (the date as of which such conversion is made pursuant to this Section 9(p)(i)(2) being hereinafter referred to as the “Judgment Conversion
Date”). 
 (ii) If in the case of any proceeding in the court of any jurisdiction referred to in
Section 9(p)(i)(2) above, there is a change in the Exchange Rate prevailing between the Judgment Conversion Date and the date of actual payment of the amount due, the applicable party shall pay such adjusted amount as may be necessary to ensure
that the 

  
 48 

 
amount paid in the Judgment Currency, when converted at the Exchange Rate prevailing on the date of payment, will produce the amount of US Dollars which could have been purchased with the amount
of Judgment Currency stipulated in the judgment or judicial order at the Exchange Rate prevailing on the Judgment Conversion Date. 

(iii) Any amount due from the Company under this provision shall be due as a separate debt and shall not be affected by
judgment being obtained for any other amounts due under or in respect of this Agreement or any other Transaction Document. 
 (q)
Independent Nature of Buyers’ Obligations and Rights. The obligations of each Buyer under the Transaction Documents are several and not joint with the obligations of any other Buyer, and no Buyer shall be responsible in any way for the
performance of the obligations of any other Buyer under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Buyer pursuant hereto or thereto, shall be deemed to constitute the Buyers
as, and the Company acknowledges that the Buyers do not so constitute, a partnership, an association, a joint venture or any other kind of group or entity, or create a presumption that the Buyers are in any way acting in concert or as a group or
entity with respect to such obligations or the transactions contemplated by the Transaction Documents or any matters, and the Company acknowledges that the Buyers are not acting in concert or as a group, and the Company shall not assert any such
claim, with respect to such obligations or the transactions contemplated by the Transaction Documents. The decision of each Buyer to purchase Securities pursuant to the Transaction Documents has been made by such Buyer independently of any other
Buyer. Each Buyer acknowledges that no other Buyer has acted as agent for such Buyer in connection with such Buyer making its investment hereunder and that no other Buyer will be acting as agent of such Buyer in connection with monitoring such
Buyer’s investment in the Securities or enforcing its rights under the Transaction Documents. The Company and each Buyer confirms that each Buyer has independently participated with the Company and its Subsidiaries in the negotiation of the
transaction contemplated hereby with the advice of its own counsel and advisors. Each Buyer shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of any
other Transaction Documents, and it shall not be necessary for any other Buyer to be joined as an additional party in any proceeding for such purpose. The use of a single agreement to effectuate the purchase and sale of the Securities contemplated
hereby was solely in the control of the Company, not the action or decision of any Buyer, and was done solely for the convenience of the Company and its Subsidiaries and not because it was required or requested to do so by any Buyer. It is expressly
understood and agreed that each provision contained in this Agreement and in each other Transaction Document is between the Company, each Subsidiary and a Buyer, solely, and not between the Company, its Subsidiaries and the Buyers collectively and
not between and among the Buyers.

SOLAR TECHNOLOGIES, INC. 
 SENIOR SECURED
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 July 18, 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 32. 

 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 25(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. 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 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 

  
 2 

 
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, (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 and (z) the applicable Make-Whole Amount, if any. 
 (ii) “Conversion
Price” means, as of any Conversion Date or other date of determination, $0.5246, 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 19(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”) . 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) 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 

  
 3 

 
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 19(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 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 

  
 4 

 
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 19,
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 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. 

  
 5 

 (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 24. 

(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][9.99]1% (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 Warrants) beneficially owned by the Holder or any other
Attribution Party subject to a limitation on conversion or exercise analogous to the limitation contained in this Section 3(d)(i). For purposes of this Section 3(d)(i), beneficial ownership shall be calculated in accordance with
Section 13(d) of the 1934 Act. For purposes of determining the number of outstanding shares of Common Stock the Holder may acquire upon the conversion of this Note without exceeding the Maximum Percentage, the Holder may rely on the number of
outstanding shares of Common Stock as reflected in (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 
  

	1 	As elected by the Holder on the applicable Issuance Date 

  
 6 

 
Company or (z) any other written notice by the Company or the Transfer Agent, if any, setting forth the number of shares of Common Stock outstanding (the “Reported Outstanding Share
Number”). If the Company receives a Conversion Notice from the Holder at a time when the actual number of outstanding shares of Common Stock is less than the Reported Outstanding Share Number, the Company shall notify the Holder in writing
of the number of shares of Common Stock then outstanding and, to the extent that such Conversion Notice would otherwise cause the Holder’s beneficial ownership, as determined pursuant to this Section 3(d)(i), to exceed the Maximum
Percentage, the Holder must notify the Company of a reduced number of shares of Common Stock to be purchased pursuant to such Conversion Notice. For any reason at any time, upon the written or oral request of the Holder, the Company shall within one
(1) Business Day confirm orally and in writing or by electronic mail to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to
the conversion or exercise of securities of the Company, including this Note, by the Holder and any other Attribution Party since the date as of which the Reported Outstanding Share Number was reported. In the event that the issuance of shares of
Common Stock to the Holder upon conversion of this Note results in the Holder and the other Attribution Parties being deemed to beneficially own, in the aggregate, more than the Maximum Percentage of the number of outstanding shares of Common Stock
(as determined under Section 13(d) of the 1934 Act), the number of shares so issued by which the Holder’s and the other Attribution Parties’ aggregate beneficial ownership exceeds the Maximum Percentage (the “Excess
Shares”) shall be deemed null and void and shall be cancelled ab initio, and the Holder shall not have the power to vote or to transfer the Excess Shares. Upon delivery of a written notice to the Company, the Holder may from time to time
increase (with such increase not effective until the sixty-first (61st) day after delivery of such notice) or decrease the Maximum Percentage to any other percentage not in excess of 9.99% as
specified in such notice; provided that (i) any such increase in the Maximum Percentage will not be effective until the sixty-first (61st) day after such notice is delivered to the
Company and (ii) any such increase or decrease will apply only to the Holder and the other Attribution Parties and not to any other holder of Notes that is not an Attribution Party of the Holder. For purposes of clarity, the shares of Common
Stock issuable pursuant to the terms of this Note in excess of the Maximum Percentage shall not be deemed to be beneficially owned by the Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the 1934 Act. No
prior inability to convert this Note pursuant to this paragraph shall have any effect on the applicability of the provisions of this paragraph with respect to any subsequent determination of convertibility. The provisions of this paragraph shall be
construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 3(d)(i) to the extent necessary to correct this paragraph (or any portion of this paragraph) which may be defective or inconsistent with
the intended beneficial ownership limitation contained in this Section 3(d)(i) or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitation contained in this paragraph may not be waived and
shall apply to a successor holder of this Note. 

  
 7 

 (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 or
exercise of the Warrants or otherwise pursuant to the terms of the Notes or the Warrants) 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
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 or any of the Warrants or otherwise pursuant to the terms of the Notes, shares of Common Stock in an amount
greater than the product of (i) the Exchange Cap as of the Issuance Date multiplied by (ii) the quotient of (1) the original principal amount of Notes issued to such Buyer pursuant to the Securities Purchase Agreement on the 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 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 such holder’s exercise in full of such
Warrants shall be allocated, to the respective Exchange Cap Allocations of the remaining holders of Notes and related Warrants on a pro rata basis in proportion to the shares of Common Stock underlying the Notes and related Warrants then held by
each such holder of Notes and related Warrants. At any time on or after the Stockholder Meeting Deadline (as defined in the Securities Purchase Agreement), 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 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 

  
 8 

 
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. 

(1) At any time during any Event of Default Redemption Right Period (as defined below) (each, an “Alternate Event of
Default Conversion Date”), the Holder may, at the Holder’s option, convert (each, an “Alternate Event of Default Conversion”) all, or any part of, the Conversion Amount (such portion of the Conversion Amount subject to
such Alternate Conversion, the “Alternate Event of Default Conversion Amount”) into shares of Common Stock at the Alternate Event of Default Conversion Price. 

(2) At any time during the period commencing on any date the Company issues any Excluded Preferred Securities in a Dilutive
Issuance (assuming, notwithstanding anything set forth herein, for the purposes of such determination pursuant to this Section 3(e)(i)(2) that such Excluded Preferred Securities are not Excluded Securities hereunder)(each, an “Preferred
Dilutive Issuance”) in which the New Issuance Price is less than or equal to $0.24 (as adjusted for stock splits, stock dividends, recapitalizations and similar events occurring after the Subscription Date) (each, an “Alternate
Preferred Eligibility Date”) through the sixty-first (61st) consecutive Trading Day (subject to adjustment as provided below) immediately following such subsequent date (each such subsequent date, an “Alternate Preferred Tail
Period Commencement Date”, and each such sixty-one (61) consecutive Trading Day period, subject to adjustment as provided below, each, an “Alternate Preferred Tail Period”) that the quotient of (x) the sum of the
VWAPs of any five consecutive Trading Days after the applicable Alternate Preferred Eligibility Date, divided by (y) five (5) is greater than $0.4197 (as adjusted for stock splits, stock dividends, recapitalizations and similar events
occurring after the Subscription Date) (each, an “Alternate Preferred Conversion Period”), the Holder may, at the Holder’s option, convert (each, an “Alternate Preferred Conversion”, and together with each
Alternate Event of Default Conversion, each, an “Alternate Conversion”, and each such date of an Alternate Preferred Conversion, an “Alternate Preferred Conversion Date”, and together with each Alternate Event of
Default Conversion Date, each an “Alternate Conversion Date”) all, or any part of, the Conversion Amount (such portion of the Conversion Amount subject to such Alternate Conversion, the “Alternate Preferred Conversion
Amount”, and together with each Alternate Event of Default Conversion Amount, each an “Alternate Conversion Amount”) into shares of Common Stock at the lowest New Issuance Price with respect to any Preferred Dilutive
Issuance during such Alternate Preferred Conversion Period (as applicable, the “Alternate Preferred Conversion Price”, and together with each Alternate Event of Default Conversion Price, each an “Alternate Conversion

  
 9 

 
Price”). Notwithstanding the foregoing, if an Equity Conditions Failure occurs on any Trading Day during an Alternate Preferred Tail Period, such Alternate Preferred Tail Period shall
be extended until such time as sixty (60) consecutive Trading Days occur without any Equity Conditions Failure. No later than the first (1st) Trading Day after (x) each Alternate
Preferred Eligibility Date, (y) the date of each Preferred Dilutive Issuance during any Alternate Preferred Conversion Period and (z) each Alternate Preferred Tail Period Commencement Date, as applicable, the Company shall deliver written
notice to the Holder specifying that (A) the applicable Alternate Preferred Eligibility Date, (B) the Alternate Preferred Conversion Price in effect as of the date of such notice and (C) if known as of the date of such notice, the
Alternate Preferred Tail Period Commencement Date and Alternate Preferred Conversion Period. For the avoidance of doubt, all determinations pursuant to this Section 3(e)(i)(2) shall be made as if the Excluded Preferred Securities are not
Excluded Securities hereunder during the applicable Alternate Preferred Conversion Period, mutatis mutandis. 
 (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) 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 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).

(vi) the Company’s or any Subsidiary’s failure to pay to the Holder any amount of Principal, Interest, Late Charges
or other amounts when and as due under this Note (including, without limitation, the Company’s or any Subsidiary’s failure to pay any redemption payments or amounts hereunder) or any other Transaction Document (as defined in the Securities

document or any such other decree, order, judgment or other similar document unstayed and in effect for a period of thirty (30) consecutive days; 

(xii) a final judgment or judgments for the payment of money aggregating in excess of $150,000 are rendered against the Company
and/or any of its Subsidiaries and which judgments are not, within thirty (30) days after the entry thereof, bonded, discharged, settled or stayed pending appeal, or are not discharged within thirty (30) days after the expiration of such
stay; provided, however, any judgment which is covered by insurance or an indemnity from a credit worthy party shall not be included in calculating the $150,000 amount set forth above so long as the Company provides the Holder a written statement
from such insurer or indemnity provider (which written statement shall be reasonably satisfactory to the Holder) to the effect that such judgment is covered by insurance or an indemnity and the Company or such Subsidiary (as the case may be) will
receive the proceeds of such insurance or indemnity within thirty (30) days of the issuance of such judgment; 
 (xiii)
the Company and/or any Subsidiary, individually or in the aggregate, either (i) fails to pay, when due, or within any applicable grace period, any payment with respect to any Indebtedness in excess of $150,000 due to any third party (other

accelerate amounts due thereunder, or (ii) suffer to exist any other circumstance or event that would, with or without the passage of time or the giving of notice, result in a default or event of default under any agreement binding the Company
or any Subsidiary, which default or event of default would or is likely to have a material adverse effect on the business, assets, operations (including results thereof), liabilities, properties, condition (including financial condition) or

five (5) consecutive Trading Days; 

  
 13

material provision of any Security Document shall at any time for any reason cease to be valid and binding on or enforceable against the Company or the validity or enforceability thereof shall be contested by any party thereto, or a proceeding shall
be commenced by the Company or any governmental authority having jurisdiction over the Company, seeking to establish the invalidity or unenforceability thereof; 

(xx) any material damage to, or loss, theft or destruction of, any Collateral, whether or not insured, or any strike, lockout,

Company or any Subsidiary, if any such event or circumstance could have a Material Adverse Effect; or 
 (xxi) any Event of
Default (as defined in the Other Notes) occurs with respect to any Other Notes. 

  
 14 

 (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 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 3(e), but subject to Section 3(d), until the Event of Default Redemption Price (together with any Late Charges thereon) is paid in full, the Conversion Amount submitted for redemption under this Section 4(b) (together with any
Late Charges thereon) may be converted, in whole or in part, by the Holder into Common Stock pursuant to the terms of this Note. 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 

  
 15 

 
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. 
 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 16, 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. 
 (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 

  
 16 

 
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 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

  
 17 

 
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 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

  
 18 

 
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 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 

  
 19 

 
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 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 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 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 

  
 20 

 
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 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 

  
 21 

 
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. Subject to Section 4(n) of the Securities Purchase Agreement and excluding any Excluded Preferred Securities, in addition to and not in limitation of the other provisions of this Section 7, 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”) after the Subscription Date that are issuable pursuant to such agreement or
convertible into or exchangeable or exercisable for shares of Common Stock pursuant to 

  
 22 

 
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 Convertible Securities or
Options, as applicable. Subject to Section 4(n) of the Securities Purchase Agreement, 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. For the avoidance of doubt,
(x) if the adjustment in the immediately preceding sentence would otherwise result in an increase in the Conversion Price hereunder, no adjustment shall be made and (y) this Section 7(d) shall only apply to the first Stock Combination
Event occurring after the initial Issuance Date and not any subsequent Stock Combination Event. 
 (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. 

  
 23 

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

(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. COMPANY 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-sixth (26th) Trading Day prior to each Installment Date (or, with respect to the initial Installment Date, the Initial Installment Notice
Due 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 

  
 24 

 
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 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

  
 25 

 
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 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 

  
 26 

 
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 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 

  
 27 

 
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 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 

  
 28 

 
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) 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 and eighty (180) 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 

  
 29 

 
Amount may be converted, in whole or in part, by the Holders into shares of Common 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 a partial redemption of this Note pursuant hereto, the Principal amount redeemed shall be deducted in reverse order starting from the final Installment Amount to be paid hereunder on the final Installment Date,
unless the Holder otherwise indicates and allocates among any Installment Dates hereunder in a written notice to the Company. 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. 

(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). 

11. RESERVATION OF AUTHORIZED SHARES. 

(a) Reservation. The Company shall initially reserve 100 million shares of Common Stock (as adjusted for stock
splits, stock dividends, recapitalizations and similar events occurring after the Subscription Date) out of its authorized and unissued Common Stock solely for the purpose of effecting the conversion of the Notes, including without limitation,
Installment Conversions and Accelerations. So long as any of the Notes are 

  
 30 

 
outstanding, the Company shall take all action necessary to reserve and keep available out of its authorized and unissued Common Stock, solely for the purpose of effecting the conversion of the
Notes, (x) if on or prior to the Share Reservation Deadline, 100 million shares of Common Stock (as adjusted for stock splits, stock dividends, recapitalizations and similar events occurring after the Subscription Date) out of its
authorized and unissued Common Stock solely for the purpose of effecting the conversion of the Notes, including without limitation, Installment Conversions and Accelerations, (less such number of shares of Common Stock issued upon conversion,
including without limitation, Installment Conversions and Accelerations of the Notes) and (y) if after the Share Reservation Deadline, 150% of the number of shares of Common Stock as shall from time to time be necessary to effect the
conversion, including without limitation, Installment Conversions and Accelerations, of all of the Notes then outstanding, provided that at no time shall the number of shares of Common Stock so reserved be less than the number of shares required to
be reserved by the previous sentence (without regard to any limitations on conversions and assuming this Note remains 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, at any time after the Stockholder Meeting Deadline, 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. At any time after the Stockholder Meeting Deadline, 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. 
 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 19(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
19(d)), 

  
 32 

 
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 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. 
 (b)
Redemption by Other Holders. Upon the Company’s receipt of notice from any of the holders of the Other Notes for redemption or repayment as a result of an event or occurrence substantially similar to the events or occurrences described
in Section 4(b) or Section 5(b) (each, an “Other Redemption Notice”), the Company shall immediately, but no later than one (1) Business Day of its receipt thereof, forward to the Holder by facsimile or electronic mail
a copy of such notice. If the Company receives a Redemption Notice and one or more Other Redemption Notices, during the seven (7) Business Day period beginning on and including the date which is three (3) Business Days prior to the
Company’s receipt of the Holder’s applicable Redemption Notice and ending on and including the date which 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

 (iv) [INSERT IF HOLDER IS INITIALLY REQUIRED TO DEPOSIT ANY AMOUNT IN A MASTER
RESTRICTED ACCOUNT PURSUANT TO THE SECURITIES PURCHASE AGREEMENT: 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 $25 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 

  
 39 

 
Securities Purchase Agreement) (each, a “Cash Payment Obligation”) from the Collateral in the Holder Master Restricted Account, including, without limitation, 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.]

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

 23. FAILURE OR INDULGENCE NOT WAIVER. No failure or delay on the part of the Holder in the
exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or
privilege. No waiver shall be effective unless it is in writing and signed by an authorized representative of the waiving party. Notwithstanding the foregoing, nothing contained in this Section 23 shall permit any waiver of any provision of
