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. 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, 2008, except as set forth on Schedule 3(n), (i) the Common Stock has been

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.

disclosed in the SEC Documents, 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). Except as disclosed in the SEC Documents, (i) none of the Company’s or any Subsidiary’s capital stock is subject to preemptive rights or any other similar rights or
any liens or encumbrances suffered or permitted by the Company or any Subsidiary; (ii) there are no outstanding options, warrants, scrip, rights to subscribe to, calls or commitments of any character whatsoever relating to, or securities or

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 securities convertible into, or exercisable or exchangeable for, shares of Common Stock and the material rights of the holders thereof in respect

including obligations so evidenced incurred in connection with the acquisition of property, assets or businesses, (E) all indebtedness created or arising under any conditional sale or other title retention agreement, or incurred as financing,

first refusal, pledge, charge, security interest or other encumbrance 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” 

  
 14 

 
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 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 a government or any department or agency thereof. 

(t) Absence of Litigation. Except as disclosed in the SEC Documents, there is no action, suit, proceeding, inquiry or
investigation before or by the Principal Market, any court, public board, government agency, 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 which is outside of the ordinary course of business or individually or in the aggregate material to the Company or any of its Subsidiaries. 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 believes that its and its Subsidiaries’ relations with their respective
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 

  
 15 

 
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. 
 (w) Title. Except as disclosed in
the SEC Documents, 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, encumbrances and defects except such 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, patents, patent rights, copyrights,
original works, 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 and as presently proposed to be conducted. None of the Company’s or its Subsidiaries’ Intellectual Property Rights have expired, terminated or been abandoned, or are expected to expire,
terminate or be abandoned, within three years from the date of this Agreement. The Company has no knowledge of any infringement by the Company or any of 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 their Intellectual Property Rights. The Company is not aware of any facts or
circumstances which might give rise to any of the foregoing infringements or claims, actions or proceedings. The Company and each of 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 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.

and 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 U.S. Internal Revenue Code of 1986, as amended. 
 (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 generally accepted
accounting principles 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. 

  
 17 

 (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.

the sale of 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”

“derivative” transaction. The Company further understands and acknowledges that following the public disclosure of the transactions contemplated by the Transaction Documents pursuant to the 8-K Filings (as defined below) one or more Buyers
may engage in hedging and/or trading activities at various times during the period that the Securities are outstanding, including, without limitation, during the periods that the value and/or number of the Warrant Shares, the Interest Shares or
Conversion Shares, as applicable, deliverable with respect to the Securities are being determined and (b) 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 on their behalf has, directly or indirectly, (i) taken any action designed to cause or to result in the stabilization or

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. Each press release issued by the Company or any of its Subsidiaries during the twelve (12) months preceding the date of this Agreement did not at the time of release contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they are 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. 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. 
  

	4.	COVENANTS.

 (b) Form D and Blue Sky. The Company agrees to file a
Form D with respect to the Securities as required under Regulation D and to provide a copy thereof to each Buyer promptly after such filing. The Company shall, on or before each Closing Date, take such action as the 

  
 21 

 
Company shall reasonably determine is necessary in order to obtain an exemption for, or to, qualify the Securities being sold at such Closing for sale to the Buyers at such Closing pursuant to
this Agreement under applicable securities or “Blue Sky” laws of the states of the United States (or to obtain an exemption from such qualification), and shall provide evidence of any such action so taken to the Buyers on or prior to such
Closing Date. Without limiting any other obligation of the Company under this Agreement, the Company shall timely make all filings and reports relating to the offer and sale of the Securities required under all applicable securities laws (including,
without limitation, all applicable federal securities laws and all applicable “Blue Sky” laws), and the Company shall comply with all applicable federal, foreign, state and local laws, statutes, rules, regulations and the like relating to

required to file reports under the 1934 Act even if the 1934 Act or the rules and regulations thereunder would no longer require or otherwise permit such termination. The Company shall take all actions necessary to maintain its eligibility to
register the Registrable Securities for resale by the Buyers on Form S-3. 
 (d) Use of Proceeds. The Company will use

Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q, any interim reports or any consolidated balance sheets, income statements, stockholders’ equity statements and/or cash flow statements for any period other than annual, any Current
Reports on Form 8-K and any registration statements (other than on Form S-8) or amendments filed pursuant to the 1933 Act, (ii) unless the following are either filed with the SEC through EDGAR or are otherwise widely disseminated via a
recognized new release service (such as PR Newswire), on the same day as the release thereof, facsimile copies of all press releases issued by the Company or any of its Subsidiaries and (iii) unless the following are filed with the SEC through
EDGAR, copies of any notices and other information made available or given to the stockholders of the Company generally, contemporaneously with the making available or giving thereof to the stockholders. 

(f) Listing. The Company shall promptly secure the listing or designation for quotation (as the case may be) of all of the
Registrable Securities upon each national securities exchange and automated quotation system, if any, upon which the Common Stock is then listed or designated for quotation (as the case may be) (subject to official notice of issuance) and shall
maintain such listing or designation for quotation (as the case may be) of all Registrable Securities from time to time issuable under the terms of the Transaction Documents on such 

  
 22 

 
national securities exchange or automated quotation system. The Company shall maintain the Common Stock’s listing or authorization for quotation (as the case may be) on the Principal Market,
The New York Stock Exchange, the NYSE Amex LLC, the Nasdaq Global Market or the Nasdaq Global Select Market (each, an “Eligible Market”). Neither the Company nor any of its Subsidiaries shall take any action which could be
reasonably expected to result in the delisting or suspension of the Common Stock on an Eligible Market. The Company shall pay all fees and expenses in connection with satisfying its obligations under this Section 4(f). 

(g) Fees. The Company shall reimburse Capital Ventures International (“Capital Ventures”) for all reasonable
costs and expenses incurred by it in connection with preparing and delivering the Transaction Documents (including, without limitation, all reasonable legal fees and disbursements in connection therewith, and due diligence in connection with the
transactions contemplated thereby), which amount may be withheld by Capital Ventures from its applicable Purchase Price at each Closing or paid by the Company on demand by Greenberg Traurig, LLP, less $30,000 which was previously advanced to Capital
Ventures by the Company, provided, however, that the amount payable by the Company to Capital Ventures hereunder shall not exceed $75,000 in the aggregate unless agreed to by the Company. The Company shall be responsible for the payment of any
placement agent’s fees, financial advisory fees, transfer agent fees, DTC (as defined below) fees or broker’s commissions (other than for Persons engaged by any Buyer) relating to or arising out of the transactions contemplated hereby
(including, without limitation, any fees payable to the Placement Agent, who is the Company’s sole placement agent in connection with the transactions contemplated by this Agreement). The Company shall pay, and hold each Buyer harmless against,
any liability, loss or expense (including, without limitation, reasonable attorneys’ fees and out-of-pocket expenses) arising in connection with any claim relating to any such payment. Except as otherwise set forth in the Transaction Documents,
each party to this Agreement shall bear its own expenses in connection with the sale of the Securities to the Buyers. 
 (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 a Buyer in connection with a bona fide margin agreement or other loan or
financing arrangement 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 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. 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. On or before 5:00 p.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 the Warrants and the form of the Registration Rights Agreement) (including all attachments, the “Initial 8-K Filing”). From and
after the filing of the Initial 8-K Filing (but prior to the delivery of an Additional Closing Notice to the Buyers), the Company shall have disclosed all material, non- 

  
 23 

 
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. On or before 8:30 a.m., New York time, on the first
(1st) Business Day after the Company delivers an
Additional Closing Notice to the Buyers, the Company shall file a Current Report on Form 8-K describing all the material terms of the Additional Closing (the “Additional 8-K Filing”, and together with the Initial 8-K Filing, the
“8-K Filings”). From and after the filing of the Additional 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. Except with respect to the delivery of the Additional Closing Notice in accordance with Section 1(b)(ii),
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 issuance of the Additional 8-K Filing without the express prior written consent of such Buyer. In the event of a breach of any of the foregoing covenants, 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, 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. 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 approval of any Buyer, to make any press release or other public disclosure with respect to such transactions (i) in substantial conformity with the 8-K Filings 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, 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 information regarding the Company or any of its Subsidiaries. 
 (j)
Additional Registration Statements. During the period commencing on the date hereof and ending ninety calendar days after the Initial Closing Date (the “Restricted Period”), the Company shall not file a registration statement
under the 1933 Act relating to securities that are not the Registrable Securities. 

  
 24 

 (k) Additional Issuance of Securities. So long as any Buyer beneficially owns any
Securities, the Company will not, without the prior written consent of Buyers holding a majority in aggregate principal amount of the Notes then outstanding, 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 during 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 “equity security” (as that term is defined under Rule 405 promulgated under the 1933 Act), any Convertible Securities (as defined below), any debt (other than Permitted Indebtedness), 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”); provided, further, that until the
eight month anniversary of the Initial Closing Date, no Subsequent Placement shall have a purchase price per share of Common Stock issued or issuable upon conversion or exercise of Convertible Securities (whether at issuance or after any subsequent
reset or amendment thereto) of less than $1.00 (as adjusted for any stock splits, stock dividends, stock combinations, recapitalization or other similar transactions). Notwithstanding the foregoing, this Section 4(k) shall not apply in respect
of the issuance of (A) 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
(1) all such issuances (taking into account the shares of Common Stock issuable upon exercise of such options) after the date hereof pursuant to this clause (A) do not, in the aggregate, exceed more than 5% of the Common Stock issued and
outstanding immediately prior to the date hereof and (2) 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; (B) 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 (A) above) issued prior to the date hereof, provided that the conversion 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 (A) above) is not lowered, 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 (A) 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 (A) above) are otherwise materially changed in any manner that adversely affects any of the Buyers; (C) the Conversion Shares, (D) the Interest Shares, and (E) the Warrant Shares (each of the
foregoing in clauses (A) through (E), collectively the “Excluded Securities”). “Approved Stock Plan” means any employee benefit plan 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 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 

  
 25 

 
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 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 120% of the sum of (i) the maximum number of Conversion Shares
issuable upon conversion of the Notes (assuming for purposes hereof that the Notes are convertible at the Conversion Price (as defined in the Notes) and without taking into account any limitations on the conversion of the Notes set forth therein),
(ii) the maximum number of Interest Shares issuable pursuant to the terms of the Notes from the Initial Closing Date through the thirty (30) month anniversary of the Initial Closing Date (determined without taking into account any
limitations on the issuance of securities set forth in the Notes and assuming all Additional Notes issuable hereunder will be issued on Additional Closing Date) and (iii) the maximum number of Warrant Shares issuable upon exercise of the
Warrants (without taking into account any limitations on the exercise of the Warrants set forth therein). 
 (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 result, either individually or in the
aggregate, in a Material Adverse Effect. 
 (n) Variable Securities. Until the first anniversary of the Initial Closing Date,
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 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) 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) 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 the Principal Market.

  
 26 

 (p) Passive Foreign Investment Company. The Company shall conduct its business in
such a manner as will ensure that the Company will not be deemed to constitute a passive foreign investment company within the meaning of Section 1297 of the U.S. Internal Revenue Code of 1986, as amended. 

(q) Restriction on Redemption and Cash Dividends. So long as any Notes are outstanding, the Company shall not, directly or
indirectly, redeem, or declare or pay any cash dividend or distribution on, any securities of the Company without the prior express written consent of the Buyers, except as required by the terms of any Excluded Securities. 

(r) Corporate Existence. So long as any Buyer owns any Notes or Warrants, the Company shall not be party to any 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 and the Warrants. 

(s) Stock Splits. Until the Notes and Warrants and all notes and warrants issued pursuant to the terms thereof are no longer
outstanding, the Company shall not effect any stock splits, stock dividends, stock combinations, recapitalizations or other similar transactions (or make any public announcement or disclosure with respect to any of the foregoing) without the prior
written consent of the Required Holders (as defined below). 
 (t) Conversion and Exercise Procedures. Each of the form
of Notice of Exercise included in the Warrants and the form of Notice of Conversion included in the Notes set forth the totality of the procedures required of the Buyers in order to exercise the Warrants or convert the Notes. Except as provided in
Section 5(d), no additional legal opinion, other information or 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, Interest Shares and Warrant Shares in accordance with the terms, conditions and time periods set forth in the Notes and Warrants. 
 (u) Closing Documents. On or prior to fourteen (14) calendar days after the Initial Closing Date, the Company agrees to deliver, or cause to be delivered, to each Buyer and Greenberg Traurig,
LLP executed copies of the Transaction Documents, Securities and other document required to be delivered to any party pursuant to Section 7 hereof. 
  

	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, the number of Interest Shares issuable with respect to 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. 

  
 27 

 (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, the Interest 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 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, Interest 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, the Interest 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 

  
 28 

 
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
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 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 two (2) Trading Days 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, Interest 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 

  
 29 

 
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, and if on or after the Required Delivery Date such Buyer (or any other Person in respect, or on behalf, of 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 so anticipated receiving from the Company without any restrictive legend, then, in addition to all other remedies available to such Buyer, the Company shall, within five (5) Trading Days after
such Buyer’s request and in such 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). 
  

	6.	CONDITIONS TO THE COMPANY’S OBLIGATION TO SELL. 

 (a) The obligation of the Company hereunder to issue and sell the Initial Notes and the related Warrants to each Buyer at such Initial Closing is subject to the satisfaction, at or before such Initial
Closing Date, of each of the following conditions, provided that these conditions are for the Company’s sole benefit and may be waived by the Company at any time in its sole discretion by providing each Buyer with prior written notice thereof:

 (i) Such Buyer shall have executed each of the other Transaction Documents to which it is a party and
delivered the same to the Company. 
 (ii) Such Buyer and each other Buyer shall have delivered to the Company

 (iii) The representations and
warranties of such Buyer shall be true and correct in all material respects as of the date when made and as of such Initial Closing Date as though originally made at that time (except for representations and warranties that speak as of a specific

 30 

 
Buyer shall have performed, satisfied and complied in all material respects with the covenants, agreements and conditions required by this Agreement to be performed, satisfied or complied with by
such Buyer at or prior to such Initial Closing Date. 
 (b) The obligation of the Company hereunder to issue and sell the

and such Buyer shall have performed, satisfied and complied in all material respects with the covenants, agreements and conditions required by this Agreement to be performed, satisfied or complied with by such Buyer at or prior to such Additional

	8.	TERMINATION. 

 In the

or after the close of business on such date without liability of such Buyer to any other party; provided, however, (i) the right to terminate this Agreement under this Section 8 shall not be available to such Buyer if the failure of the
transactions contemplated by this Agreement to have been consummated by such date is the result of such Buyer’s breach of this Agreement and (ii) the abandonment of the sale and purchase of the Notes and the Warrants shall be applicable
only to such Buyer providing such written notice, provided further that no such termination shall affect any obligation of the Company under this Agreement to reimburse such Buyer for the expenses described in Section 4(g) above. Nothing
contained in this Section 8 shall be deemed to release any party from any liability for any breach by such party of the terms and provisions of this Agreement or the other Transaction Documents or to impair the right of any party to compel
specific performance by any other party of its obligations under this Agreement or the other Transaction Documents. 

  
 34 

	9.	MISCELLANEOUS. 

 (a)
Governing Law; Jurisdiction; Jury Trial. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of New York, without giving effect to any
choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. Each party hereby irrevocably
submits to the exclusive jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or
discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an
inconvenient forum or that the venue of such suit, action or proceeding is improper. 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 IN CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY. 
 (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. 

  
 35 

 (d) Severability. 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 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 solely with respect to the 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 

  
 36 

 
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 (1) applies to less than all of the holders of the Securities then outstanding 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 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). 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 (i) 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 (ii) 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 Additional Closing Date, each Buyer entitled to purchase Notes at a
Closing hereunder and (ii) on or after Additional Closing Date, holders of all Registrable Securities (excluding any Registrable Securities held by the Company or any of its Subsidiaries) issued or issuable hereunder or pursuant to the Notes
and/or the Warrants. 
 (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, if delivered personally; (ii) when sent, if sent by facsimile (provided confirmation of transmission is mechanically or
electronically generated and kept on file by the sending party); (iii) when sent, if sent by e-mail (provided that such sent e-mail is kept on file (whether electronically or otherwise) by the sending party and the sending party does not
receive an automatically generated message from the recipient’s e-mail server that such e-mail could not be delivered to such recipient) and (iv) if sent by overnight courier service,

 (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 assignee of any of the
Securities. 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) and except that (i) the Placement Agent is an intended third party beneficiary of Sections 2 and 3 hereof and (ii) the Placement Agent shall be permitted to rely on the legal opinions identified in
Section 7(a)(ii) hereof. 
 (i) Survival. The representations, warranties, agreements and covenants shall survive
each 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, 

  
 39 

 
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 (a) any
misrepresentation or breach of any representation or warranty made by the Company or any Subsidiary in any of the Transaction Documents, (b) any breach of any covenant, agreement or obligation of the Company or any Subsidiary contained in any
of the Transaction Documents or (c) 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 on behalf of the Company or any Subsidiary) or
which otherwise involves such Indemnitee that arises out of or results from (i) the execution, delivery, performance or enforcement of any of the Transaction Documents, (ii) any transaction financed or to be financed in whole or in part,
directly or indirectly, with the proceeds of the issuance of the Securities, (iii) any disclosure properly made by such Buyer pursuant to Section 4(i), or (iv) 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. 
 (m) Remedies. Each
Buyer and each holder of any 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. 

  
 40 

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

  
 41 

 
the Judgment Conversion Date and the date of actual payment of the amount due, the applicable party shall pay such adjusted amount as may be necessary to ensure that the amount paid in the
Judgment Currency, when converted at the Exchange Rate prevailing on the date of payment, will produce the amount of US Dollars which could have been purchased with the amount of Judgment Currency stipulated in the judgment or judicial order at the
Exchange Rate prevailing on the Judgment Conversion Date. 
 (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. 
 (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.

SENIOR CONVERTIBLE NOTE 

 

			
	 Issuance Date: November     , 2011
	 	Original Principal Amount: U.S. $[            ]

 FOR VALUE RECEIVED, Odyssey Marine Exploration, Inc., a Nevada corporation (the
“Company”), hereby promises to pay to the order of [BUYER] or its registered assigns (“Holder”) the amount set out 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), acceleration,
redemption or otherwise (in each case in accordance with the terms hereof) and to pay interest (“Interest”) on any outstanding Principal (as defined below) at the applicable Interest Rate (as defined below) from the date set out
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, acceleration,
conversion, redemption or otherwise (in each case in accordance with the terms hereof). This Senior Convertible Note (including all Senior Convertible Notes issued in exchange, transfer or replacement hereof, this “Note”) is one of
an issue of Senior Convertible Notes issued pursuant to the Securities Purchase Agreement (as defined below) either on the Initial Closing Date (as defined below) or, if 

 
applicable, on the Additional Closing Date (as defined below) (collectively, the “Notes” and such other Senior Convertible Notes, the “Other Notes”). Certain
capitalized terms used herein are defined in Section 30. 
 1. PAYMENTS OF PRINCIPAL. On each Installment Date
(which includes the Maturity 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 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 the first Trading
Day of each Fiscal Quarter after the Issuance Date (each, an “Interest Date”) with the first Interest Date being January 2, 2012 and shall compound each month and shall be payable in accordance with the terms of this Note.
Interest shall be payable on each Interest Date prior to the Initial Installment Date in cash and, thereafter, Interest shall be paid on each Installment Date occurring on an Interest Date in accordance with Section 8 below. 

(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 11. From and after the occurrence and during the continuance
of an Event of Default, the Interest Rate shall be increased to fifteen percent (15.0%). In the event that such Event of Default is subsequently cured, the automatic increase to the Interest Rate referred to in the preceding sentence shall cease to
be effective as of 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.
[INSERT IN INITIAL NOTES: This] [INSERT IN ADDITIONAL NOTES: At any time or times on or after the six month anniversary of the Issuance Date (the “Initial Convertibility 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 [INSERT IN INITIAL NOTES: Issuance Date] [INSERT IN ADDITIONAL NOTES: Initial
Convertibility Date], the Holder shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount (as defined 

  
 2 

 
below) into validly issued, fully paid and non-assessable shares of Common Stock in accordance with Section 3(c), at the Conversion Rate (as defined below). The Company shall not issue any
fraction of a share of Common Stock upon any conversion. If the issuance would result in the issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock up to the nearest whole share. The
Company shall pay any and all transfer, stamp, issuance and similar taxes 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 portion of the Principal to be converted, redeemed or otherwise with
respect to which this determination is being made, plus 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.

 (ii) “Conversion Price” means, as of any Conversion Date or other date of determination,
$3.74, 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 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 18(b)). On or before the first
(1st) Trading Day following the date of receipt of a
Conversion Notice, the Company shall transmit by facsimile an acknowledgment of confirmation, in the form attached hereto as Exhibit II, of receipt of such Conversion Notice to the Holder and the Transfer Agent. On or before the second
(2nd) Trading Day following the date of receipt of a
Conversion Notice, the Company shall (1) provided that the Company’s transfer agent (the “Transfer Agent”) is participating in The Depository Trust Company’s (“DTC”) Fast Automated Securities Transfer
Program, credit such aggregate number of shares of Common Stock to which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system or (2) if the Transfer
Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver (via reputable overnight courier) to the address as specified in the Conversion Notice, a certificate, registered in the name of the Holder

  
 3 

 
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 18(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. 
 (ii) Company’s Failure to Timely Convert. If the Company shall fail, for any reason or for no reason, to issue to the Holder within three (3) Trading Days after the Company’s receipt
of a Conversion Notice (whether via facsimile or otherwise) (the “Share Delivery Deadline”), 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 (or any other Person in respect, or on behalf, of 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 written
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 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 (A) such number of shares of Common Stock
multiplied by (B) the lowest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date of the applicable Conversion Notice and ending on the date of such issuance and payment under this clause (ii).

  
 4 

 (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 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 18, 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 its receipt of such a request, then the Register shall be automatically 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) and the dates of such conversions and/or payments (as the case may be) or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this
Note upon conversion. 
 (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 23. 

  
 5 

 (d) Limitations on Conversions. 

(i) Beneficial Ownership. Notwithstanding anything to the contrary contained in this Note, this Note shall not be
convertible by the Holder hereof, and the Company shall not effect any conversion of this Note or otherwise issue any shares of Common Stock pursuant hereto, to the extent (but only to the extent) that after giving effect to such conversion or other
share issuance hereunder the Holder or any of its affiliates would beneficially own in excess of 4.99% (the “Maximum Percentage”) of the Common Stock. To the extent the above limitation applies, the determination of whether
this Note shall be convertible (vis-à-vis other convertible, exercisable or exchangeable securities owned by the Holder or any of its affiliates) and of which such securities shall be convertible, exercisable or exchangeable (as among all
such securities owned by the Holder and its affiliates) shall, subject to such Maximum Percentage limitation, be determined on the basis of the first submission to the Company for conversion, exercise or exchange (as the case may be). No prior
inability to convert this Note, or to issue shares of Common Stock, 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. For
purposes of this paragraph, beneficial ownership and all determinations and calculations (including, without limitation, with respect to calculations of percentage ownership) shall be determined in accordance with Section 13(d) of the 1934 Act
(as defined in the Securities Purchase Agreement) and the rules and regulations promulgated thereunder. The provisions of this paragraph shall be implemented in a manner otherwise than in strict conformity with the terms of this paragraph to correct
this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Maximum Percentage beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to
such Maximum Percentage limitation. The limitations contained in this paragraph shall apply to a successor Holder of this Note. The holders of Common Stock shall be third party beneficiaries of this paragraph and the Company may not waive this
paragraph without the consent of holders of a majority of its Common Stock. 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 to the Holder
the number of shares of Common Stock then outstanding, including by virtue of any prior conversion or exercise of convertible or exercisable securities into Common Stock, including, without limitation, pursuant to this Note or securities issued
pursuant to the Securities Purchase Agreement. By written notice to the Company, any Holder may increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% specified in such notice; provided that (i) any such
increase will not be effective until the 61st day after such notice is delivered to the Company, and (ii) any such increase or decrease will apply only to the Holder sending such notice and not to any other holder of Notes. 

(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 would exceed the aggregate number of shares of Common Stock which the Company may issue upon

  
 6 

 
exercise or conversion (as the case may be) of the Warrants and the Notes or otherwise pursuant to the terms of the Notes without breaching the Company’s obligations under the rules or
regulations of the Principal Market (the number of shares which may be issued without violating such rules and regulations, the “Exchange Cap”), except that such limitation shall not apply in the event that the Company
(A) obtains the approval of its stockholders as required by the applicable rules of the Principal Market for issuances of shares of Common Stock in excess of such amount or (B) obtains a written opinion from outside counsel to the Company
that such approval is not required, which opinion shall be reasonably satisfactory to the Holder. Until such approval or such written opinion is obtained, no Buyer (as defined in the Securities Purchase Agreement) shall be issued in the aggregate,
upon conversion or exercise (as the case may be) of any Notes or any of the Warrants or any other issuance pursuant to the terms of the Notes, shares of Common Stock in an amount greater than the product of (i) the Exchange Cap as of the
Issuance Date multiplied by (ii) the quotient of (1) the original principal amount of Notes issued to such Buyer pursuant to the Securities Purchase Agreement on the Initial Closing Date (as defined in the Securities Purchase Agreement)
divided by (2) the aggregate original principal amount of all Notes issued to the Buyers pursuant to the Securities Purchase Agreement on the Initial Closing Date (with respect to each Buyer, the “Exchange Cap Allocation”). In
the event that any Buyer shall sell or otherwise transfer any of such Buyer’s Notes, the transferee shall be allocated a pro rata portion of such Buyer’s Exchange Cap Allocation with respect to such portion of such Notes so transferred,
and the restrictions of the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation so allocated to such transferee. Upon conversion and exercise in full of a holder’s Notes 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 Warrants on a pro rata basis in proportion to the shares of Common Stock underlying the Notes and Warrants then
held by each such holder. In the event that the Company is prohibited from issuing shares of Common Stock pursuant to this Section 3(d)(ii) (the “Exchange Cap Shares”), the Company shall pay cash in exchange for the
cancellation of such shares of Common Stock at a price 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 such Exchange Cap
Shares would otherwise be required to be delivered to the Holder hereunder and (ii) to the extent the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of
Exchange Cap Shares, any brokerage commissions and other out-of-pocket expenses, if any, of the Holder incurred in connection therewith. 
 4. RIGHTS UPON EVENT OF DEFAULT. 
 (a) Event of
Default. Each of the following events shall constitute an “Event of Default”: 

  
 7 

 (i) a Current Public Information Failure (as defined in the Registration
Rights Agreement) or the suspension from trading or the failure of the Common Stock to be trading or listed (as applicable) on an Eligible Market for a period of five (5) consecutive days or for more than an aggregate of ten (10) days in
any 365-day period; 
 (ii) the Company’s (A) failure to cure a Conversion Failure or a Delivery
Failure (as defined in the Warrants) by delivery of the required number of shares of Common Stock within five (5) Trading Days after the applicable Conversion Date or exercise date (as the case may be) or (B) notice, written or oral, to
any holder of the Notes or Warrants, including, without limitation, by way of public announcement or through any of its agents, at any time, of its intention not to comply, as required, with a request for conversion of any Notes into shares of
Common Stock that is requested in accordance with the provisions of the Notes, other than pursuant to Section 3(d), or a request for exercise of any Warrants for Warrant Shares in accordance with the provisions of the Warrants; 

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

(iv) 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 Purchase Agreement) or any other agreement, document, certificate or other instrument delivered in connection with the transactions contemplated hereby and thereby, except, in the case of a failure to pay Interest and Late Charges when
and as due, in which case only if such failure remains uncured for a period of at least five (5) days; 

(v) the Company fails to remove any restrictive legend on any certificate or any shares of Common Stock issued to the
Holder upon conversion or exercise (as the case may be) of any Securities acquired by the Holder under the Securities Purchase Agreement (including this Note) as and when required by such Securities or the Securities Purchase Agreement, unless
otherwise then prohibited by applicable state or federal securities laws, and any such failure remains uncured for at least five (5) days; 
 (vi) the occurrence of any default under, redemption of or acceleration prior to maturity of an aggregate amount of Indebtedness (as defined in the Securities Purchase Agreement) in excess of $100,000 of
the Company or any of its Subsidiaries, other than with respect to any Other Notes; 
 (vii) bankruptcy,
insolvency, reorganization or liquidation proceedings 

  
 8 

 
or other proceedings for the relief of debtors shall be instituted by or against the Company or any Subsidiary and, if instituted against the Company or any Subsidiary by a third party, shall not
be dismissed within thirty (30) days of their initiation; 
 (viii) the commencement by the Company or any
Subsidiary of a voluntary case or proceeding under any applicable federal, state or foreign bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by
it to the entry of a decree, order, judgment or other similar document in respect of the Company or any Subsidiary in an involuntary case or proceeding under any applicable federal, state or foreign bankruptcy, insolvency, reorganization or other
similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under any applicable federal, state or foreign law, or the
consent by it to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or any Subsidiary or of any substantial part of
its property, or the making by it of an assignment for the benefit of creditors, or the execution of a composition of debts, or the occurrence of any other similar federal, state or foreign proceeding, or the admission by it in writing of its
inability to pay its debts generally as they become due, the taking of corporate action by the Company or any Subsidiary in furtherance of any such action or the taking of any action by any Person to commence a Uniform Commercial Code foreclosure
sale or any other similar action under federal, state or foreign law; 
 (ix) the entry by a court of (i) a
decree, order, judgment or other similar document in respect of the Company or any Subsidiary of a voluntary or involuntary case or proceeding under any applicable federal, state or foreign bankruptcy, insolvency, reorganization or other similar law
or (ii) a decree, order, judgment or other similar document adjudging the Company or any Subsidiary as bankrupt or insolvent, or approving as properly filed a petition seeking liquidation, reorganization, arrangement, adjustment or composition
of or in respect of the Company or any Subsidiary under any applicable federal, state or foreign law or (iii) a decree, order, judgment or other similar document appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or
other similar official of the Company or any Subsidiary or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree, order, judgment or other similar document or any
such other decree, order, judgment or other similar document unstayed and in effect for a period of thirty (30) consecutive days; 
 (x) a final judgment or judgments for the payment of money aggregating in excess of $100,000 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 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 $100,000 amount set forth above so long as the Company 

  
 9 

 
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;

within any applicable grace period, any payment with respect to any Indebtedness in excess of $100,000 due to any third party (other than, with respect to unsecured Indebtedness only, payments contested by the Company and/or such Subsidiary (as the
case may be) in good faith by proper proceedings and with respect to which adequate reserves have been set aside for the payment thereof in accordance with GAAP) or is otherwise in breach or violation of any agreement for monies owed or owing in an
amount in excess of $100,000, which breach or violation permits the other party thereto to declare a default or otherwise 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 prospects of the Company or any of its Subsidiaries, individually or in the aggregate; 

(xii) other than as specifically set forth in another clause of this Section 4(a), the Company or any Subsidiary

three (3) consecutive Trading Days; 
 (xiii) any breach or failure in any respect by the Company or any
Subsidiary to comply with any provision of Section 13 of this Note, except, in the case of a breach of Section 13(j) or 13(k) that is curable, only if such breach remains uncured for a period of five (5) consecutive Trading Days; or

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

(b) Notice of an Event of Default; Redemption Right. Upon the occurrence of an Event of Default with respect to
this Note or any Other Note, the Company shall within one (1) Business Day deliver written notice thereof via facsimile 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, the Holder may require the Company to redeem (regardless of whether such Event of Default has been cured) 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 

  
 10 

 
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 11. To the extent redemptions required by this Section 4(b) are deemed or determined by a court of competent jurisdiction to be prepayments of this Note by the Company, such redemptions shall be deemed to be voluntary
prepayments. Notwithstanding anything to the contrary in this Section 4, but subject to Section 3(d), until the Event of Default Redemption Price (together with any Late Charges thereon) is paid in full, the Conversion Amount submitted for
redemption under this Section 4(b) (together with any Late Charges thereon) may be converted, in whole or in part, by the Holder into Common Stock pursuant to the terms of this Note. In the event of a partial redemption of this Note pursuant
hereto, the Principal amount redeemed shall be deducted from the Installment Amount(s) relating to the applicable Installment Date(s) as set forth in the Event of Default Redemption Notice. In the event of the Company’s redemption of any
portion of this Note under this Section 4(b), the Holder’s damages would be uncertain and difficult to estimate because of the parties’ inability to predict future interest rates and the uncertainty of the availability of a suitable
substitute investment opportunity for the Holder. Accordingly, any redemption premium due under this Section 4(b) is intended by the parties to be, and shall be deemed, a reasonable estimate of the Holder’s actual loss of its investment
opportunity and not as a penalty 
 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), 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 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 

  
 11 

 
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
the Company’s Common Stock (or other securities, cash, assets or other property (except such items still issuable under Sections 6 and 14, which shall continue to be receivable thereafter) issuable upon the conversion or redemption of the Notes
prior to such Fundamental Transaction, such shares of the publicly traded common stock (or their equivalent) of the Successor Entity (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 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 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 greater 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 at the time of delivery by the
Holder of the Change of Control Redemption Notice 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 

  
 12 

 
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 11 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 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 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 before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is
taken, the date as of which the record holders of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, to the extent that the Holder’s right to participate in any such Purchase Right would
result in the Holder exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Purchase Right to such extent 

  
 13 

 
(or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until
such time, if ever, as its right thereto would not result in the Holder exceeding the Maximum Percentage). 
 (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 insure that the Holder will thereafter have the right to receive upon a conversion of this
Note (i) in addition to the shares of Common Stock receivable upon such conversion, such securities or other assets to which the Holder would have been entitled with respect to such shares of Common Stock had such shares of Common Stock been
held by the Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility of this Note) or (ii) in lieu of the shares of Common Stock otherwise receivable upon such
conversion, such securities or other assets received by the holders of shares of Common Stock in connection with the consummation of such Corporate Event in such amounts as the Holder would have been entitled to receive had this Note initially been
issued with conversion rights for the form of such consideration (as opposed to shares of Common Stock) at a conversion rate for such consideration commensurate with the Conversion Rate. Provision made pursuant to the preceding sentence shall be in
a form and substance 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 Subdivision or Combination of Common Stock. Without limiting any provision
of Section 5 , if the Company at any time on or after the Subscription Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) 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 , if the Company at any time on or after the Subscription Date combines (by combination,
reverse stock split or otherwise) 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(a) shall become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment under this Section 7(a) 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. 
 (b) Resets to the Conversion Price. [INSERT IN INITIAL NOTES ONLY: On the six month anniversary of the Initial Closing Date (the “Initial Reset Date”) the Conversion Price shall be
reset to the lesser of (A) the Conversion Price then in effect and 

  
 14 

 
(B) the greater of (x) $1.44 (as adjusted for any stock splits, stock dividends, stock combinations, recapitalizations or other similar transactions) and (y) 110% of the Market Price as
of the Initial Reset Date.] 
 [INSERT IN ADDITIONAL NOTES ONLY: If immediately following the close of business on (A) the
date the applicable Registration Statement filed pursuant to the Registration Rights Agreement shall be effective and the prospectus contained therein shall be available for the resale by the Holder of all of the Registrable Securities (which,
solely for clarification purposes, includes all shares of Common Stock issuable upon conversion of the Initial Notes and the Additional Notes or otherwise pursuant to the terms of the Initial Notes and the Additional Notes and upon exercise of the
Warrants (without regard for any limitations on conversion, issuance or exercise set forth therein) in accordance with the terms of the Registration Rights Agreement) or, (B) if earlier, each of (x) the six month anniversary of the
Additional Closing Date and (y) the Initial Effective Date (as defined in the Registration Rights Agreement) (each, as applicable, an “Additional Reset Date”), the Conversion Price then in effect exceeds the greater of
(I) $1.44 (as adjusted for any stock splits, stock dividends, stock combinations, recapitalizations or other similar transactions) and (II) 110% of the Market Price as of such Additional Reset Date (the “Adjusted Conversion
Price”), the Conversion Price hereunder shall be reset to the Adjusted Conversion Price as of such Additional Reset Date.] 
 (c) 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. 
 8. COMPANY INSTALLMENT CONVERSION OR REDEMPTION. 
 (a) General. On each applicable Installment Date, 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 “Company Conversion”); provided, however, the Company may, at its option as described below, pay all or any part of such Installment Amount by redeeming such Installment Amount in cash (a
“Company Redemption”) or by any combination of a Company Conversion and a Company Redemption so long as the entire amount of such Installment Amount due shall be converted and/or redeemed by the Company on the applicable Installment
Date, subject to the provisions of this Section 8, provided further that the Company shall not be entitled to effect a Company Conversion with respect to any portion of such Installment Amount and shall be required to elect and to pay the
entire amount of such Installment Amount in cash pursuant to a Company Redemption if on the applicable Installment Notice Due Date or on the applicable Installment Date (as the case may be) there is an Equity Conditions Failure, except that a
Company Conversion may still occur on the applicable Installment Date in accordance with Section 8(b) with the written consent of the Holder if the Company properly elected a Company Conversion with respect to such Installment Date. On or prior
to the date which is the eleventh (11th) Trading Day
prior to 

  
 15 

 
each Installment Date (each, an “Installment Notice Due Date”), the Company shall deliver written notice (each, a “Company Installment Notice” and the date all
of the holders receive such notice is referred to as to the “Company Installment Notice Date”), to each holder of Notes and such Company Installment Notice shall (i) either (A) confirm that the applicable Installment
Amount of such holder’s Note shall be converted in whole pursuant to a Company Conversion or (B) (1) state that the Company elects to redeem, or is required to elect and redeem in accordance with the provisions of the Notes, in whole
or in part, the applicable Installment Amount pursuant to a Company Redemption and (2) specify the portion of the applicable Installment Amount which the Company elects, or is required to elect and redeem, pursuant to a Company Redemption (such
amount to be redeemed in cash, the “Company Redemption Amount”) and the portion of the applicable Installment Amount, if any, with respect to which the Company will, and is permitted to, effect a Company 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 “Company Conversion Amount”), which amounts when added together, must equal the entire applicable
Installment Amount and (ii) if the applicable Installment Amount is to be paid, in whole or in part, pursuant to a Company Conversion, certify that there is not then an Equity Conditions Failure as of the date of the applicable Company
Installment Notice. Each Company Installment Notice shall be irrevocable and may not be revoked by the Company. If the Company does not timely deliver a Company Installment Notice in accordance with this Section 8 with respect to a particular
Installment Date, then the Company shall be deemed to have delivered an irrevocable Company Installment Notice confirming a Company 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 on the applicable Installment Notice Due Date and the applicable Installment Date. 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 Company Conversion Amount (whether set forth in the applicable Company Installment Notice or by operation of this Section 8) shall be converted in accordance with Section 8(b) and the
applicable Company Redemption Amount shall be redeemed in accordance with Section 8(c). Notwithstanding anything herein to the contrary, (i) to the extent the Equity Conditions with respect to the Additional Notes have not been satisfied
(or waived) as of the applicable Installment Date, but the Equity Conditions with respect to the Initial Notes have been satisfied as of such Installment Date, the applicable Installment Amount for such Installment Date for all such Notes shall be
satisfied (x) first, from the Initial Notes until the entire Conversion Amount of the Initial Notes has been included in such Installment Amount and (y) thereafter, from the Additional Notes and (ii) to the extent the Equity
Conditions with respect to all the Notes have been satisfied (or waived) as of the applicable Company Installment Notice Date, the Holder may, by delivery of written notice to the Company, elect to have the applicable Installment Amount satisfied
from such portion of the Initial Notes and/or Additional Notes as set forth in such notice. 

  
 16 

 (b) Mechanics of Company Conversion. Subject to
Section 3(d), if the Company delivers a Company Installment Notice and elects, or is deemed to have delivered a Company Installment Notice and deemed to have elected, in whole or in part, a Company Conversion in accordance with
Section 8(a), then the remainder of this Section 8(b) shall apply. The applicable Company Conversion Amount, if any, which remains outstanding as of the applicable Installment Date shall be converted as of the applicable Installment Date
by converting on such Installment Date such Company Conversion Amount at the Company Conversion Price and the Company shall, on the applicable 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 last sentence of this Section 8(b)), provided that there is no Equity Conditions Failure as of such Installment Date and a
Company Conversion is not otherwise prohibited under any other provision of this Note. If there is an Equity Conditions Failure as of such Installment Date or a Company 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 Company
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 Company Conversion shall be null and void with respect to all or any part designated by the Holder of the unconverted Company 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 Company Conversion Amount; provided, however, the Conversion Price for such designated part of such unconverted Company Conversion Amount
shall thereafter be adjusted to equal the lesser of (A) the Company Conversion Price as in effect on the date on which the Holder voided the Company Conversion and (B) the Company 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. 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 on the applicable Installment Date, then
the Holder shall have the rights set forth in Section 11(a) as if the Company failed to pay the applicable Company 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)(xiii)). Notwithstanding anything to the contrary in this Section 8(b), but subject to Section 3(d), until the Company delivers Common Stock representing the Company Conversion
Amount to the Holder, the Company 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 Company Conversion Amount prior to the applicable Installment Date as
set forth in the immediately preceding sentence, the Company 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. 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 Company Conversion hereunder. 

  
 17 

 (c) Mechanics of Company Redemption. If the Company elects, or is
required to elect, a Company Redemption, in whole or in part, in accordance with Section 8(a), then the Company Redemption Amount, if any, which is to be paid to the Holder on the applicable Installment Date shall be redeemed by the Company on
such Installment Date in an amount of cash, and the Company shall pay to the Holder on such Installment Date, by wire transfer of immediately available funds an amount, equal to the applicable Company Redemption Amount (the “Company
Installment Redemption Price”). If the Company fails to redeem the applicable Company Redemption Amount on the applicable Installment Date by payment of the Company Installment Redemption Price on such date, 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 Company Redemption Amount at the Company
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 Company Installment Redemption Price (together with any Late Charges thereon) is paid in full, the Company 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 Company Redemption Amount prior to the applicable Installment Date as set
forth in the immediately preceding sentence, the Company 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 11. 
 (d)
Deferred Installment Amount. Notwithstanding any provision of this Section 8 to the contrary, the Holder may, at its option and in its sole discretion, deliver a written notice to the Company at least two (2) days prior to any
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”) 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 (ii) the Deferral Amount and (ii) the date that such Deferral Amount shall now be payable. Any amount deferred to the Maturity Date pursuant to this Section 8(d) shall continue to
accrue Interest through the Maturity Date and shall be paid on such date in cash. 
 9. 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, the Company (i) shall not increase the par
value of any shares of Common Stock receivable upon conversion of this Note 

  
 18 

 
above the Conversion Price then in effect, (ii) 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 (iii) 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). 
 10. RESERVATION OF AUTHORIZED SHARES. 

(a) Reservation. The Company shall initially reserve out of its authorized and unissued Common Stock a number of
shares of Common Stock for each of the Notes equal to 120% of the entire Conversion Rate with respect to the entire Conversion Amount of each such Note as of the Issuance Date. So long as any of the Notes are 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, 120% of the number of shares of Common Stock as shall from time to time be necessary to
effect the conversion 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) (the “Required Reserve Amount”). The initial number of shares of Common Stock reserved for conversions of the Notes and each increase in the number of shares so reserved shall be allocated pro rata among
the holders of the Notes based on the original principal amount of the Notes held by each holder on the Initial Closing Date or increase in the number of reserved shares (as the case may be) (the “Authorized Share Allocation”). In
the event that a holder shall sell or otherwise transfer any of such holder’s Notes, each transferee shall be allocated a pro rata portion of such holder’s Authorized Share Allocation. Any shares of Common Stock reserved and allocated to
any Person which ceases to hold any Notes shall be allocated to the remaining holders of Notes, pro rata based on the principal amount of the Notes then held by such holders. 

(b) Insufficient Authorized Shares. If, notwithstanding Section 10(a), and not in limitation thereof, at any
time while any of the Notes remain outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon conversion of the Notes at least a number of
shares of Common Stock equal to the Required Reserve Amount (an “Authorized Share Failure”), then the Company shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock to an amount
sufficient to allow the Company to reserve the Required Reserve Amount for the Notes then outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure,
but in no event later than sixty (60) 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 

  
 19 

 
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. Nothing contained in Section 10(a) or this Section 10(b) shall limit any obligations of the Company under any provision of the Securities Purchase Agreement. 

11. HOLDER’S REDEMPTIONS. 
 (a) Mechanics. The Company shall deliver the applicable Event of Default Redemption Price to the Holder in cash within two (2) 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 Fundamental Transaction if such notice is received prior to the consummation of such Fundamental Transaction and within two (2) Business Days after the Company’s receipt of such notice
otherwise. The Company shall deliver the applicable Company Installment Redemption Price to the Holder in cash on the applicable Installment Date. [INSERT IN ADDITIONAL NOTES ONLY: The Company shall deliver the applicable Company Optional Redemption
Price to the Holder in cash on the applicable Company Optional Redemption Date.] 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 18(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 18(d)), to the Holder, and in each case the principal amount of this Note or
such new Note (as the case may be) shall be increased by an amount equal to the difference between (1) the applicable Redemption Price 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) 75% 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) 75% of the arithmetic average of the VWAPs of the Common Stock for the five (5) Trading Day period immediately preceding the Conversion Date of the
applicable conversion. 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. 

  
 20
