 2. Exercise of Warrant. 

(a) Manner of Exercise. 
 (i) Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial Exercise Date and on or before the Expiration Date by
delivery to the Company (or such other office or agency of the Company as it may designate by notice in writing to the registered Holder at the address of the Holder appearing on the books of the Company) of a duly executed facsimile copy of the
Notice of Exercise Form annexed hereto. Within three (3) Trading Days following the date of exercise as aforesaid, the Holder shall deliver the aggregate Exercise Price for the shares specified in the applicable Notice of Exercise by wire
transfer or cashier’s check drawn on a United States bank unless the cashless exercise procedure specified in Section 2(c) below is specified in the applicable Notice of Exercise. Notwithstanding anything herein to the contrary, the Holder
shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant
to the Company for cancellation within three (3) Trading Days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares
available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing
the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise Form within one (1) Business Day of receipt of such notice. The Holder and any assignee, by acceptance
of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be
less than the amount stated on the face hereof. 

  
 - 2 –

 (ii) Cashless Exercise. Notwithstanding the provisions of Section 2(a)(i)
above (requiring payment by wire transfer), the Company agrees that, if at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of the Warrant
Shares to the Holder, then Holder shall have the right at such time to exercise this Warrant in full or in part on a cashless basis, computed using the following formula: 
 X = Y (A - B) 
      A 

Where: 
 X =
The number of Warrant Shares to be issued to the Holder pursuant to this cashless exercise; 
 Y = The number of Warrant Shares
in respect of which the net issue election is made; 
 A = The Fair Market Value (as defined below) of one Warrant Share at the
time the cashless exercise election is made; and 
 B = The Exercise Price then in effect at the time of such exercise.

 The term “Fair Market Value” shall mean, on any given day: (A) if the class of Warrant Shares is
exchange-traded, the average of the closing sales prices per share of the class of Warrant Shares for the trading day prior to the applicable date of determination of Fair Market Value; or (B) if the class of Warrant Shares is not listed or
admitted to trading on any securities exchange but is regularly traded in any over-the-counter market, then the average of the bid and ask prices per share of the class of Warrant Shares for trading day prior to the applicable date of determination
of Fair Market Value; or (C) if the class of Warrant Shares is not traded as described in clauses (A) or (B), then the per share fair market value of the class of Warrant Shares as determined in good faith by the Company’s Board of
Directors. 
 (b) Delivery of Certificates. The Company shall, at its own cost and expense, cause the transfer agent to
deliver such certificates to the Holder (or to such other nominee as may be designated by the Holder) within three Business Days following the Date of Exercise (the “Delivery Period”). The Holder shall be deemed for all corporate
purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised as of the Date of Exercise, irrespective of the date such certificates are actually delivered by the transfer agent to the
Holder or are credited to the Holder’s Depository Trust Company (“DTC”) account, as the case may be. If fewer than all of the Warrant Shares purchasable under the Warrant are purchased, the Company will, upon such partial
exercise, execute and deliver to the Holder a new Warrant (dated as of the Issue Date), in the same form and tenor as this Warrant, evidencing that portion of the Warrant not exercised. 

(c) Delivery of Electronic Shares. In lieu of delivering physical certificates representing the Warrant Shares issuable upon
exercise (provided that the transfer agent is participating in the DTC Fast Automated Securities Transfer program and provided further that the Holder provides the transfer agent with information required in order to issue such Warrant Shares to the
Holder electronically), upon the request of the Holder as set forth in the Notice of Exercise, the Company shall cause its transfer agent to electronically transmit, within the Delivery Period, the Warrant Shares issuable upon exercise to the Holder
by crediting Holder’s account with DTC through its Deposit Withdrawal Agent Commission system. Any delivery not effected by electronic transmission shall be effected by delivery of physical certificates. 

  
 - 3 –

 (d) No Fractional Shares. If a fractional share of Warrant Shares would, but for the
provisions of this Section 2(d), be issuable upon exercise of the rights represented by this Warrant, the Company shall (i) round a half share or greater to be delivered to Holder up to the next whole share and (ii) round a
less-than-half share to be delivered to Holder down to the nearest whole share. 
 (e) Buy-In. Notwithstanding anything
else to the contrary contained herein, in addition to any other rights available to the Holder, if the Company fails to cause its transfer agent to transmit to the Holder a certificate or certificates representing the applicable Warrant Shares
purchased upon exercise hereof or credit the Holder’s balance account with DTC, as applicable, on or before the end of the Delivery Period (other than a failure caused by any incorrect or incomplete information provided by Holder to the Company
hereunder), and if after such date the Holder purchases shares of Common Stock to deliver in satisfaction of a sale by the Holder of Warrant Shares that the Holder anticipated receiving from the Company upon exercise of this Warrant (a
“Buy-In”), then the Company shall, within three Business Days after the Holder’s request, (1) pay cash to the Holder the amount by which (x) the Holder’s total purchase price (including commissions, if any) for
the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue, by (B) the price
at which the sell order giving rise to such purchase obligation was executed, and (2) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored, or
deliver to the Holder the number of Warrant Shares that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. The Holder shall provide the Company written notice indicating the amounts payable
to the Holder in respect of the Buy-In, together with applicable confirmations and other evidence reasonably requested by the Company. Nothing herein shall limit the Holder’s right to pursue any other remedies available to it hereunder, at law
or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing the Securities as required pursuant to the terms hereof.

 (f) No Charge to Holder Upon Issuance. The issuance of Warrant Shares upon exercise of this Warrant shall be made
without charge to Holder for any issuance tax in respect thereof or other cost incurred by the Company in connection with such exercise and the related issuance of Warrant Shares (other than any transfer taxes resulting from the issuance of Warrant
Shares to any person other than Holder). 
 (g) Reservation of Shares. During the Exercise Period, the Company shall
reserve and keep available out of its authorized but unissued Common Stock such number of Warrant Shares issuable upon the full exercise of this Warrant. All Warrant Shares which are so issuable shall, when issued and upon the payment of the
applicable Exercise Price, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges and not subject to the pre-emptive rights of any holder of Common Stock or any other class or series of stock of the
Company. During the Exercise Period, the Company shall not take any action which would cause the number of authorized but unissued Common Stock to be less than the number of such shares required to be reserved hereunder for issuance upon exercise of
this Warrant. 

  
 - 4 –

 (h) Limitations on Exercises. Notwithstanding anything to the contrary contained in
this Warrant, this Warrant shall not be exercisable by the Holder hereof to the extent (but only to the extent) that the Holder or any of its affiliates would beneficially own in excess of 9.8% (the “Maximum Percentage”) of the
Common Stock. To the extent the above limitation applies, the determination of whether this Warrant shall be exercisable (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 exercisable (as among all such securities owned by the Holder) 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 exercise this Warrant pursuant to this paragraph shall have any effect on the applicability of the provisions of this paragraph with respect to any subsequent determination of exercisability. For
the 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
Exchange Act. The limitations contained in this paragraph shall apply to a successor Holder of this Warrant. 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. The provisions of this
Section 2(h)(i) may be waived by such Holder, at the election of such Holder, upon not less than 61 days’ prior notice to the Company, and the provisions of this Section 2(h)(i) shall continue to apply until such 61st
day (or such later date, as determined by such Holder, as may be specified in such notice of waiver). Notwithstanding anything else set forth herein, in no event shall this Warrant be exercisable by the Holder to the extent that the Holder or any of
its affiliates and any other Person whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”),
would beneficially own in excess of 19.99% of the number of shares of the Company’s Common Stock outstanding at the time of such issuance unless any issuances in excess of the foregoing limitation are approved by the Company’s common
stockholders. 
 3. Adjustments in Certain Events. The number, class, and price of Warrant Shares for which this Warrant may be exercised
are subject to adjustment from time to time upon the happening of certain events as follows: 
 (a) Subdivisions,
Combinations and Other Issuances. If the outstanding shares of the Company’s Common Stock are divided into a greater number of shares, by forward stock split or otherwise, or a dividend in stock is paid on the Common Stock, then the number
of shares of Warrant Shares for which the Warrant is then exercisable will be proportionately increased and the Exercise Price will be proportionately reduced. Conversely, if the outstanding shares of Common Stock are combined into a smaller number
of shares of Common Stock, by reverse stock split or otherwise, then the number of Warrant Shares for which the Warrant is then exercisable will be proportionately reduced and the Exercise Price will be proportionately increased. The increases and
reductions provided for in this Section 3(a) will be made with the intent and, as nearly as practicable, the effect that neither the percentage of the total equity of the Company obtainable on exercise of the Warrants nor the price
payable for such percentage upon such exercise will be affected by any event described in this Section 3(a). 

  
 - 5 –

 (b) Merger, Consolidation, Reclassification, Reorganization, Etc. In case of any
change in the Common Stock through merger, consolidation, reclassification, reorganization, partial or complete liquidation, purchase of all or substantially all the assets of the Company, or other change in the capital structure of the Company,
then, as a condition of such change, lawful and adequate provision will be made so that the Holder will have the right thereafter to receive upon the exercise of the Warrant the kind and amount of shares of stock or other securities or property to
which he would have been entitled if, immediately prior to such event, he had held the number of Warrant Shares obtainable upon the exercise of the Warrant. In any such case, appropriate adjustment will be made in the application of the provisions
set forth herein with respect to the rights and interest thereafter of the Holder, to the end that the provisions set forth herein will thereafter be applicable, as nearly as reasonably may be, in relation to any shares of stock or other property
thereafter deliverable upon the exercise of the Warrant. The Company will not permit any change in its capital structure to occur unless the issuer of the shares of stock or other securities to be received by the Holder, if not the Company, agrees
to be bound by and comply with the provisions of this Warrant. 
 (c) Notice of Record Date, Etc. In the event the
Company shall propose to take any action of the types requiring an adjustment pursuant to this Section 3 or a dissolution, liquidation or winding up of the Company shall be proposed, the Company shall give notice to Holder as provided in
Section 6 below, which notice shall specify the record date, if any, with respect to any such action and the date on which such action is to take place. Such notice shall also set forth such facts with respect thereto as shall be
reasonably necessary to indicate the effect of such action (to the extent such effect may be known at the date of such notice) on the Exercise Price and the number, kind or class of shares or other securities or property which shall be deliverable
or purchasable upon the occurrence of such action or deliverable upon the exercise of the Warrant. In the case of any action which will require the fixing of a record date, unless otherwise provided in this Warrant, such notice shall be given at
least twenty (20) days prior to the date so fixed, and in case of all other action, such notice shall be given at least thirty (30) days prior to the taking of such proposed action. 

(d) If securities of the Company or securities of any subsidiary of the Company are distributed pro rata to holders of Common Stock, such
number of securities will be distributed to the Holder or its assignee upon exercise of its rights hereunder as such Holder or assignee would have been entitled to if this Warrant had been exercised prior to the record date for such distribution.
The provisions with respect to adjustment of the Common Stock provided in this Section 3 will also apply to the securities to which the Holder or its assignee is entitled under this Section 3(d). 

4. No Rights as a Stockholder. Except as otherwise provided herein, the Holder will not, by virtue of ownership of the Warrant, be entitled to any
rights of a stockholder of the Company but will, upon written request to the Company, be entitled to receive such quarterly or annual reports as the Company distributes to its stockholders.

as applicable, at the respective addresses set forth on the signature page to this Warrant or at such other address(es) as they may designate, respectively, by ten (10) days advance written notice to the other party hereto. 

(ii) Upon the occurrence of any adjustments pursuant to Sections 3 or 4 hereof, the Company at its expense shall, as promptly as
reasonably practicable but in any event not later than 10 days thereafter, compute such adjustment in accordance with the terms hereof and furnish to Holder a certificate setting forth such adjustment and showing in detail the facts upon which such
adjustment is based. 
 6. Non-Circumvention. The Company hereby covenants and agrees that the Company will not, by amendment of its
certificate of incorporation, bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other action, avoid or seek to avoid the observance or performance
of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be reasonably required to protect the rights of the Holder. 

7. Governing Law. This Warrant shall be governed by and construed in accordance with the laws of the State of New York, without regard to conflict
of law principles, and notwithstanding the fact that one or more counterparts hereof may be executed outside of the state, or one or more of the obligations of the parties hereunder are to be performed outside of the state. 

8. Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Warrant, and, in the case of loss, theft, or destruction, of indemnity reasonably satisfactory to it, and, if mutilated, upon surrender and cancellation of this Warrant, the Company will execute and deliver a new
Warrant, having terms and conditions identical to this Warrant, in lieu hereof. 
 9. Modification and Waiver. The Warrant and any
provision hereof may be amended, waived, discharged or terminated only by an instrument in writing signed by the Company and the Holder of the Warrant. 
 10. Successors. This Warrant shall be binding and inure to the benefit of the parties and their respective successors and assigns hereunder; provided that this Warrant may be assigned by Holder
only in compliance with the conditions specified in and in accordance with all of the terms of this Warrant. This Warrant does not create and shall not be construed as creating any rights enforceable by any other person or corporation.

 11. Headings. The headings used in this Warrant are used for convenience only and are not to be
considered in construing or interpreting this Warrant. 
 12. Saturdays, Sundays, Holidays. If the last or appointed day for the taking
of any action or the expiration of any right required or granted herein shall be a Saturday or a Sunday or shall be a legal holiday in the State of New York, then such action may be taken or such right may be exercised on the next
succeeding day not a legal holiday. 
 13. Severability. If any provision of this Warrant shall be held to be invalid or unenforceable,
such invalidity or unenforceability shall not affect any other provisions of this Warrant. 
 14. Execution and Counterparts. This
Warrant may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed an original, and such counterparts together shall constitute only one instrument. Any one of such counterparts shall be sufficient
for the purpose of proving the existence and terms of this Warrant, and no party shall be required to produce an original or all of such counterparts in making such proof.

 ARTICLE III. 
 REPRESENTATIONS AND WARRANTIES 

3.1 Representations and Warranties of the Company. The Company hereby represents and warrants to the Purchaser as follows:

 (a) The Company meets the requirements for use of Form S-3 under the Securities Act for a primary
offering. A Registration Statement on Form S-3 (No. 333-161220) with respect to the Units, including a base prospectus (the “Base Prospectus”), and such amendments to such registration statement as may have been required
prior to the date of this Agreement, has been prepared by the Company pursuant to and conforms in all material respects with the requirements of the Securities Act, and has been filed with the Commission under the Securities Act. Such Registration
Statement has been declared effective by the Commission. Copies of such registration statement, including any amendments thereto, each related preliminary prospectus (meeting the requirements of Rules 430, 430A or 430B under the Securities Act)
contained therein, and the exhibits, financial statements and schedules thereto have heretofore been delivered by the Company to the Purchaser. A final prospectus supplement containing information permitted to be omitted at the time of effectiveness
by Rules 430A or 430B under the Securities Act will be filed by the Company with the Commission in accordance with Rule 424(b) under the Securities Act. The term “Registration Statement” as used herein means the
aforementioned registration statement as amended at the time it became effective by the Commission under the Securities Act (the “Effective Date”), including the Base Prospectus and financial statements, all exhibits and all
documents and filings incorporated by reference therein and, if applicable, the information deemed to be included by Rules 430A, 430B or 430C under the Securities Act. If an abbreviated registration statement is prepared

  
 5 

 
and filed with the Commission in accordance with Rule 462(b) under the Securities Act (an “Abbreviated Registration Statement”), the term “Registration
Statement” as used in this Agreement includes the Abbreviated Registration Statement. The term “Prospectus” as used herein means, together with the Base Prospectus, the final prospectus supplement relating to the Units as
filed with the Commission pursuant to Rule 424(b) under the Securities Act that discloses the public offering price and other final terms of the Units, and includes the documents and filings incorporated by reference therein. Any reference in
this Agreement to the Registration Statement, Base Prospectus or the Prospectus shall include the documents and filings incorporated by reference therein. All references in this Agreement to financial statements and schedules and other information
or reports that is “contained,” “included,” “described,” “referenced,” “disclosed,” “set forth” or “stated” in the Registration Statement, the Base Prospectus or the Prospectus
(and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information or reports (including the Company’s reports filed with the Commission pursuant to the Exchange Act)
that is or is deemed to be incorporated by reference in the Registration Statement, the Base Prospectus or the Prospectus, as the case may be. The Prospectus delivered to the Purchaser for use in connection with the offering of the Units has been
and will be identical to the version thereof transmitted to the Commission for filing via the Electronic Data Gathering Analysis and Retrieval System, except to the extent permitted by Regulation S-T. For purposes of this Agreement, the words
“amend,” “amendment,” “amended,” “supplement” or “supplemented” with respect to the Registration Statement or the Prospectus shall mean amendments or supplements to the Registration Statement or the
Prospectus, as the case may be, as well as the documents and filings filed after the date of this Agreement or the issue date of the Base Prospectus or the Prospectus, as the case may be, and are deemed to be incorporated therein by reference.

 (b) Neither the Commission nor any state or other jurisdiction or other regulatory body has issued, and
neither is, to the knowledge of the Company, threatening to issue, any stop order under the Securities Act or other order suspending the effectiveness of the Registration Statement (as amended or supplemented) or preventing or suspending the use of
the Prospectus or suspending the qualification or registration of the Units for offering or sale in any jurisdiction nor instituted or, to the knowledge of the Company, threatened to institute proceedings for any such purpose. The Registration
Statement at the Effective Date, as of 5:30 p.m., New York City time, on the date hereof (the “Initial Time of Sale”) and at all times during which a prospectus is required by the Securities Act to be delivered in connection with
the sale of the Units (the “Prospectus Delivery Period”), and the Prospectus and any amendments or supplements thereto or to the Registration Statement when they are filed with the Commission or become effective, as the case may be,
contain or will contain, as the case may be, all statements that are required to be stated therein by, and in all material respects conform or will conform, as the case may be, as of the date of its delivery to the Purchaser and at all times during
the Prospectus Delivery Period, to the requirements of, the Securities Act. Neither the Registration Statement nor any amendment thereto, as of the applicable effective date, contains or will contain, as the case may be, any untrue statement of a
material fact or omits or will omit to state any material fact required to be stated therein or necessary to make the statements therein, not misleading. Neither the Prospectus nor any supplement thereto contains, as of the date thereof, or will
contain, as the case may be, any untrue statement of a material fact or omits or will omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were
made, not misleading. The 

  
 6 

 
Prospectus contains all information required under the Securities Act with respect to the Units and the distribution of the Units. Each of the documents incorporated by reference or deemed to be
incorporated by reference in the Registration Statement at the time such document was filed with the Commission, or at the time such document became effective, as applicable, complied in all material respects with the requirements of the Exchange
Act. Any future documents incorporated by reference so filed, when they are filed, will comply in all material respects with the requirements of the Exchange Act. No such incorporated document as described in either of the prior two sentences
contained or will contain any untrue statement of a material fact or omit, or will omit, to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they are made,
not misleading; and, when read together and with the other information in the Prospectus, at the time the Registration Statement became effective, as of the date hereof, at the Initial Time of Sale and at the Closing Date, each document incorporated
by reference into the Registration Statement did not or will not, as the case may be, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not
misleading. 
 (c) The Company has been duly incorporated and is validly existing as a corporation in good
standing under the laws of the State of Delaware, with full power and authority (corporate and otherwise) to own its properties and conduct its business as described in the Prospectus, and has been duly qualified as a foreign corporation for the
transaction of business and is in good standing under the laws of each other jurisdiction in which it owns or leases properties or conducts any business so as to require such qualification, except where the failure to be so qualified or in good
standing would not, individually or in the aggregate, be reasonably expected to result in a Material Adverse Effect. 
 (d) The Company has the full corporate power and authority to enter into and to consummate the transactions contemplated by each of the Transaction Documents (as defined below) and otherwise to carry out
its obligations hereunder and thereunder. The execution and delivery of each of the Transaction Documents by the Company and the consummation by it of the transactions contemplated hereby and thereby have been duly authorized by all necessary action
on the part of the Company and other than with respect to the Required Approvals (as defined in Section 3.1(f)) no further consent or action is required by the Company, its Board of Directors or its shareholders. Each of the Transaction
Documents has been (or upon delivery will be) duly executed by the Company and is, or when delivered in accordance with the terms hereof, will constitute, the valid and binding obligation of the Company enforceable against the Company in accordance
with its terms, except as such enforceability may be limited by applicable (x) general equitable principles and bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or similar laws in effect which affect creditors’
rights generally, or (y) laws relating to the availability of specific performance, injunctive relief or other equitable remedies or (z) insofar as indemnification and contribution provisions may be limited by applicable law. The
execution, delivery and performance of the Transaction Documents by the Company and the consummation by the Company of the transactions contemplated hereby and thereby do not and will not: (i) conflict with or violate any provision of the
Company’s certificate of incorporation, bylaws or other organizational or charter documents in effect as 

  
 7 

 
of the date of execution of this Agreement, or (ii) subject to obtaining (A) the Required Approvals (as defined below) and (B) shareholder approval of the decision of the
Company’s board of directors’ to the Company’s certificate of incorporation to increase the number of authorized shares of Common Stock, if necessary, conflict with, breach, or constitute a default (or an event that with notice or
lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation (with or without notice, lapse of time or both) of, any Permit (as defined below), agreement, mortgage,
indenture, credit facility, indebtedness or other instrument (evidencing a Company indebtedness or otherwise) or other understanding to which the Company is a party or by which any property or asset of the Company is bound or affected, or
(iii) result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Company is subject (including federal and state securities laws and
regulations), or by which any property or asset of the Company is bound or affected, except in the case of each of clauses (ii) and (iii) immediately above, such as could not, individually or in the aggregate: (a) adversely affect the
legality, validity or enforceability of this Agreement and any other documents or agreements executed in connection with the transactions contemplated hereunder (collectively, the “Transaction Documents”), (b) could reasonably
be expected to have or result in a material adverse effect on the results of operations, assets, business, management, operations or financial condition of the Company and its subsidiaries, taken as a whole, or (c) adversely impair the
Company’s ability to perform fully on a timely basis its obligations under any of the Transaction Documents (any of foregoing clauses (a), (b) or (c), a “Material Adverse Effect”). 

(e) Neither the Company nor any of its subsidiaries is (i) in violation of its certificate of incorporation, bylaws
or other organizational or charter documents in effect as of the date of execution of this Agreement or (ii) in default in the performance or observance of any material obligation, agreement, covenant or condition contained in any agreement,
mortgage, indenture, credit facility, indebtedness or other instrument (evidencing a Company indebtedness or otherwise) or other understanding to which the Company or any of its subsidiaries is a party or by which any property or asset of the
Company or any of its subsidiaries is bound or affected, except such as could not, individually or in aggregate, have a Material Adverse Effect. 
 (f) The Company is not required to obtain any consent, approval, waiver, authorization or order of, give any notice to, or make any filing or registration with, or qualification of, any court or other
federal, state, local or other governmental authority or other Person in connection with the execution, delivery and performance by the Company of the Transaction Documents, other than (i) the filing of a Form 8-K disclosing the transaction
contemplated hereby, (ii) the filing with the Commission of a prospectus supplement, (iii) notification for the listing of the shares of Common Stock issued as part of the Units by the Nasdaq Stock Market (the “Principal
Market”) for trading thereon in the manner required thereby, and (iv) applicable state securities filings (collectively, the “Required Approvals”). 

(g) Each of the Company and its subsidiaries is, and at all times in the last three years has been, in full
compliance with all laws, statutes, rules, regulations, or guidance applicable to the conduct of the Company’s business, taken as a whole, except where such noncompliance would not, individually or in the aggregate, be reasonably expected to
have 

  
 8 

 
a Material Adverse Effect. None of the Company, its subsidiaries, or agents operating on its behalf have received any notice or claim from any third party alleging that the Company’s actions
violate any applicable laws governing the privacy, storage, distribution or solicitation of personal information, including, without limitation, under the Health Insurance Portability and Accountability Act, as amended, and the rules and regulations
promulgated thereunder. 
 (h) All agreements required to be filed as exhibits to all reports required to be
filed by the Company under the Securities Act and Exchange Act since the Company’s most recent Annual Report on Form 10-K under Item 601 of Regulation S-K to which the Company or any of its subsidiaries is a party, have been filed by
Company as exhibits to such reports (the “Material Contracts”). The Material Contracts have been duly authorized, executed and delivered by the Company or its subsidiaries, constitute valid and binding agreements of the Company or
its subsidiaries (as applicable) and are enforceable against the Company or its subsidiaries (as applicable) in accordance with their respective terms, except as such enforceability may be limited by (i) general equitable principles and
bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or similar laws in effect which affect creditors’ rights generally, (ii) laws relating to the availability of specific performance, injunctive relief or other
equitable remedies, and (iii) insofar as indemnification and contribution provisions may be limited by applicable law, and, to the Company’s knowledge, such Material Contracts are enforceable in accordance with their respective terms by
the Company or its subsidiaries (as applicable) against the other parties thereto, except as such enforceability may be limited by (x) general equitable principles and bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or
similar laws in effect which affect creditors’ rights generally, (y) laws relating to the availability of specific performance, injunctive relief or other equitable remedies, and (z) insofar as indemnification and contribution
provisions may be limited by applicable law, and such contracts are in full force and effect on the date hereof other than those which have expired in accordance with their terms. Neither the Company nor any of its subsidiaries, nor, to the
Company’s knowledge, any other party thereto, is in breach of or default under any of such Material Contracts, except for such breaches or defaults that will not, individually or in the aggregate, be reasonably expected to result in a Material
Adverse Effect. 
 (i) As of September 20, 2011, the authorized capital stock of the Company consists of
(i) 75,000,000 shares of Common Stock, of which (A)46,346,678 shares are issued and outstanding; (B) 4,993,690 shares are reserved for issuance upon exercise of stock options outstanding under the Company’s equity compensation plans;

Except as disclosed in the Prospectus, there are no legal or governmental actions, suits or proceedings pending or, to the Company’s knowledge, threatened to which the Company or any of its subsidiaries is or may be a party or of which property
owned or leased by the Company or any of its subsidiaries is or may be the subject, or related to environmental or discrimination matters, which actions, suits or proceedings, would reasonably be expected, individually or in the aggregate, to have a
Material Adverse Effect. No labor disturbance by the employees of the Company or any of its subsidiaries exists or, to the knowledge of the Company, is imminent that would reasonably be expected to have a Material Adverse Effect. Neither the Company

reasonably be expected to have a Material Adverse Effect. 
 (k) Except as disclosed in the Prospectus, each of
the Company and its subsidiaries owns or has the valid right to use all Intellectual Property (as defined below) necessary for the conduct of the businesses of the Company and its subsidiaries in the manner described in the Prospectus as now
conducted or proposed to be conducted. Except as disclosed in the Prospectus, (i) to the knowledge of the Company, no third party has infringed, misappropriated, diluted or otherwise violated in any material respect any Intellectual Property
rights of the Company or any of its subsidiaries, and no claims for any of the foregoing have been brought against any third party by the Company or any of its subsidiaries; (ii) the Intellectual Property owned by the Company or its
subsidiaries and, to the knowledge of the Company, the Intellectual Property licensed to the Company or its subsidiaries have not been adjudged invalid or unenforceable, in whole or in part, and there is no pending or, to the knowledge of the
Company, threatened action, suit, proceeding, investigation or claim challenging the validity, enforceability, scope, issuance/registration, use or ownership of any such Intellectual Property, and the Company is unaware of any facts which would form
a reasonable basis for any such claim; (iii) there is no pending or, 

  
 10 

 
to the knowledge of the Company, threatened action, suit, proceeding or claim by others that the Company or any of its subsidiaries infringes, misappropriates, dilutes or otherwise violates any
Intellectual Property of others, and none of the Company or any of its subsidiaries has received any written notice of any such claim, and the Company is unaware of any facts which would form a reasonable basis for any such claim; (iv) each of
the Company and its subsidiaries has taken commercially reasonable steps, consistent with industry standards, to maintain and protect all Intellectual Property that is material to the conduct of its business; and (v) to the knowledge of the

dress, domain names, copyrights, licenses, inventions, trade secrets, technology, software, systems, know-how and other intellectual property and proprietary rights. 

(l) The Company does not own any real property. The Company and its subsidiaries have good and marketable title to all
real property and tangible properties and assets described in the Prospectus as owned by it, in each case free and clear of all Liens, except such as (i) are described in the Prospectus or (ii) 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 its subsidiaries. Any real property and buildings held under lease by the Company and its subsidiaries are held by them under valid,
subsisting and enforceable leases with such exceptions as do not interfere with the use made and proposed to be made of such property and buildings by the Company and its subsidiaries. 

(m) The Company and its subsidiaries possess all licenses, certificates, clearances, authorizations or permits issued by
the appropriate governmental or regulatory agencies or authorities (collectively, “Permits”) that are necessary to enable them to own, lease and operate their respective properties and to carry on their respective businesses as
presently conducted, except where the failure to possess such licenses, certificates, authorization or permits would not reasonably be expected to have a Material Adverse Effect. The Company has not received notice of any revocation or modification
of any such Permits and has no reason to believe that any such license, certificate, permit or authorization will not be renewed in the ordinary course. The Company has not received any Form 483 notice of adverse finding from the U.S. Food and Drug
Administration (“FDA”), warning letter, untitled letter or other correspondence or notice from FDA or any other governmental or regulatory authority alleging or asserting noncompliance with any applicable laws or any Permits. The Company
has filed, obtained, maintained or submitted all material reports, documents, forms, notices, applications, records, claims, submissions and supplements or amendments as required by any applicable laws or Permits and that all such reports,
documents, forms, notices, applications, records, claims, submissions and supplements or amendments were complete and correct on the date filed in all material respects (or were corrected or supplemented by a subsequent submission).

Company nor it subsidiaries are bound by any agreement that adversely affects the exclusive right of the Company to develop, manufacture, produce, assemble, distribute, license, market or sell its products. 

(o) The Company, on behalf of itself and its subsidiaries, carries, or is covered by, insurance from insurers of
recognized financial responsibility in such amounts and covering such risks as is customary for companies engaged in similar businesses in similar industries. All policies of insurance of the Company and its subsidiaries are in full force and
effect; each of the Company and its subsidiaries is in compliance with the terms of such policies in all material respects; and none of the Company or its subsidiaries has received notice from any insurer or agent of such insurer that capital
improvements or other expenditures are required or necessary to be made in order to continue such insurance; there are no claims by the Company or any of its subsidiaries under any such policy or instrument as to which any insurance company is
denying liability or defending under a reservation of rights clause; and none of the Company or its subsidiaries has any reason to believe that it will not be able 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 could not reasonably be expected to have a Material Adverse Effect. 

(p) Each of the Company and its subsidiaries (i) is in compliance in all material respects with any and all
applicable foreign, federal, state and local laws and regulations relating to the protection of human health and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants (collectively, “Environmental
Laws”), (ii) has received and is in compliance with all Permits required of it under applicable Environmental Laws to conduct its business and (iii) has not received notice of any actual or potential liability for the
investigation or remediation of any disposal or release of hazardous or toxic substances or wastes, pollutants or contaminants, except where such non-compliance with Environmental Laws, failure to receive required Permits, or liability would not,
individually or in the aggregate, have a Material Adverse Effect, whether or not arising from transactions in the ordinary course of business, except as set forth in the Prospectus. The Company has not been named as a “potentially responsible
party” under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended. 

(q) (i) Each “employee benefit plan” (within the meaning of Section 3(3) of the Employee Retirement
Security Act of 1974, as amended (“ERISA”)) for which the Company or any member of its “Controlled Group” (defined as any organization which is a member of a controlled group of corporations within the meaning of
Section 414 of the Internal Revenue Code of 1986, as amended (the “Code”)) would have any liability (each a “Plan”) has been maintained in all material respects in compliance with its terms and with the
requirements of all applicable statutes, rules and regulations including ERISA and the Code; (ii) with respect to each Plan subject to Title IV of ERISA (a) no “reportable event” (within the meaning of Section 4043(c) of
ERISA) has occurred or is reasonably expected to occur, (b) no “accumulated funding deficiency” (within the meaning of Section 302 of ERISA or Section 412 of the Code), whether or not waived, has occurred or is reasonably

  
 12 

 
expected to occur, (c) the fair market value of the assets under each Plan exceeds the present value of all benefits accrued under such Plan (determined based on those assumptions used to
fund such Plan) and (d) neither the Company nor any member of its Controlled Group has incurred, or reasonably expects to incur, any liability under Title IV of ERISA (other than contributions to the Plan or premiums to the Pension Benefit
Guaranty Corporation in the ordinary course and without default) in respect of a Plan (including a “multiemployer plan”, within the meaning of Section 4001(c)(3) of ERISA); and (iii) each Plan that is intended to be qualified
under Section 401(a) of the Code is so qualified and nothing has occurred, whether by action or by failure to act, which would cause the loss of such qualification. 

(r) The Company has filed all federal, state, local and foreign income and franchise tax returns required to be filed
through the date hereof, subject to permitted extensions, and has paid all taxes due thereon, and no tax deficiency has been determined adversely to the Company, nor does the Company have any knowledge of any tax deficiencies that could, in the
aggregate, reasonably be expected to have a Material Adverse Effect. There is no pending dispute with any taxing authority relating to the Company’s payment of taxes in any material amount except which the Company is contesting in good faith
and the Company has no knowledge of any proposed liability for any tax to be imposed upon the properties or assets of the Company for which there is not an adequate reserve reflected in the Company’s financial statements included or
incorporated by reference in the Prospectus. 
 (s) All corporate action required to be taken by the Company for
the authorization, issuance and sale of the Units has been duly and validly taken. When the shares of Common Stock comprising the Units and the shares of Common Stock issuable upon exercise of the Warrants have been issued and delivered against
payment therefor as provided herein and in the Warrants, as the case may be, such shares of Common Stock, when so issued and delivered, and such shares of Common Stock issuable upon exercise of the Warrants, when issued upon exercise of the
Warrants, will be duly and validly issued, fully paid and non-assessable and the Investors or other persons in whose names such securities are registered will acquire good and valid title to such securities, in each case free and clear of all Liens.
The Units (and the securities comprising the Units) will conform in all material respects to the description thereof contained in the Registration Statement and the Prospectus. No further approval or authority of the stockholders or the Board of
Directors of the Company will be required for the issuance and sale of the Units, the shares of Common Stock comprising part of the Units, the Warrants or the shares of Common Stock issuable upon exercise of the Warrants as contemplated herein. The
Warrants conform, or when issued will conform, to the description thereof contained in the Prospectus and have been duly and validly authorized by the Company and upon delivery to the Purchaser at the Closing Date will be valid and binding
obligations of the Company, enforceable in accordance with their terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the rights and remedies of creditors generally or
subject to general principles of equity. The sale of the securities contemplated by this Agreement is in compliance with the requirements set forth in Instruction I.B.6 of Form S-3. 

(t) The issuance by the Company of the Common Stock and Warrants which comprise the Units has been registered under the
Securities Act and the shares of Common Stock and Warrants which comprise the Units are freely transferable by the Purchaser without restriction as described in the Prospectus. 

  
 13 

 (u) Neither the Company, nor any of its Affiliates, nor any Person acting on
its or their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the Units to be integrated with prior offerings by the
Company for purposes of any applicable stockholder approval provisions, including, without limitation, under the rules and regulations of any exchange or automated quotation system on which any of the securities of the Company are listed or
designated, nor will the Company take any action or steps that would cause the offering of the Units to be integrated with other offerings. Except as disclosed in the Prospectus, the Company has not, in the twelve (12) months preceding the date
hereof, received notice from the Principal Market to the effect that the Company is not in compliance with the listing or maintenance requirements of the Principal Market. Except as described in the Prospectus, the Company has no reason to believe
that it will not in the foreseeable future continue to be in compliance or regain compliance in a timely manner, as the case may be, with all such listing and maintenance requirements. The issuance and sale of the Units hereunder does not
contravene, in a manner which is expected to have a Material Adverse Effect, the rules and regulations of the Principal Market and no stockholder approval is required for the Company to fulfill its obligations under the Transaction Documents. The
Common Stock has been registered pursuant to Section 12(b) of the Exchange Act and is currently listed on the Principal Market. 
 (v) The Company has filed all reports required to be filed by it under the Exchange Act, including pursuant to Section 13(a) or 15(d) thereof, for the two years preceding the date hereof (the
foregoing materials being collectively referred to herein as the “Commission Reports”) on a timely basis or has received a valid extension of such time of filing and has filed any such Commission Reports prior to the expiration of
any such extension. Each Purchaser acknowledges that the Company has filed a Form 12b-25 with the Commission with respect to its Annual Report on Form 10-K for the fiscal year ended June 30, 2011. As of their respective dates, the Commission
Reports complied in all material respects with the requirements of the Exchange Act and the rules and regulations promulgated thereunder, and none of the Commission Reports, when filed, contained any untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. 

(w) The Company is in compliance in all material respects with all provisions of the Sarbanes-Oxley Act of 2002, as
amended, applicable to it, and the applicable rules and regulations promulgated thereunder by all government and regulatory authorities and agencies. The Company maintains a system of internal accounting controls sufficient to provide reasonable
assurance 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 in the United States and to maintain accountability for assets, (iii) access to assets is permitted only in accordance with management’s general or specific authorization and (iv) the recorded
accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect thereto. The Company has established and maintains and evaluates “disclosure controls and procedures”

  
 14 

 
(as such term is defined in Rule 13a-15 and Rule 15d-15 under the Exchange Act) and “internal control over financial reporting” (as such term is defined in Rule 13a-15 and Rule 15d-15
under the Exchange Act). The Company’s certifying officers have evaluated the effectiveness of the Company’s disclosure controls and procedures and the Company presented in its Form 10-Q for the fiscal quarter ended March 31, 2011,
the conclusions of the Company’s certifying officers about the effectiveness of such disclosure controls and procedures. 
 (x) The financial statements of the Company, together with the related schedules and the notes thereto, included or incorporated by reference in the Registration Statement and the Prospectus comply in all
material respects with applicable accounting requirements and the applicable requirements of the Securities Act and Exchange Act as in effect at the time of filing. Such financial statements have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis during the periods involved (“GAAP”), except as may be otherwise specified in such financial statements or the notes thereto, and fairly present in all material respects the
financial position of the Company as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, immaterial, year-end audit adjustments. EisnerAmper
LLP, who has audited certain financial statements of the Company, are independent registered public accountants as required by the Securities Act and Exchange Act and have been appointed by the Company’s audit committee (if so empowered by the
Board of Directors) comprised only of independent directors, or by the Board of Directors, as the case may be. 

(y) Since the date of the latest audited financial statements included in the Prospectus, except as disclosed in the
Prospectus: (i) there has been no event, occurrence or development that, individually or in the aggregate, has had or could result in a Material Adverse Effect, (ii) the Company has not incurred any liabilities (contingent or otherwise)
other than (A) trade payables and accrued expenses incurred in the ordinary course of business consistent with past practice and (B) liabilities not required to be reflected in the Company’s financial statements pursuant to GAAP or
required to be disclosed in filings made with the Commission, (iii) the Company has not altered its method of accounting or the identity of its auditors, (iv) other than with respect to the Company’s outstanding shares of Series B
Convertible Preferred Stock and Series C Convertible Preferred Stock, the Company has not declared or made any dividend or distribution of cash or other property to its shareholders or purchased, redeemed or made any agreements to purchase or redeem
any shares of its capital stock, and (v) the Company has not issued any equity securities to any officer, director or Affiliate, except pursuant to existing equity compensation plans of the Company. Other than as set forth in the Prospectus,
the Company does not have pending before the Commission any request for confidential treatment of information. Except for the issuance of the Units contemplated by this Agreement or as set forth in the Prospectus, no event, liability or development
has occurred or exists with respect to the Company or its subsidiaries or their respective business, properties, operations or financial condition, that would be required to be disclosed by the Company under applicable securities laws at the time
this representation is made or deemed made that has not been publicly disclosed at least one Trading Day prior to the date that this representation is made. 

  
 15 

 (z) Except as set forth in or incorporated into the Prospectus, none of the
officers or directors of the Company and, to the knowledge of the Company, none of the employees of the Company is presently a party to any transaction with the Company or any subsidiary (other than for services as employees, officers and
directors), including any contract, agreement or other arrangement providing for the furnishing of services to or by, providing for rental of real or personal property to or from, or otherwise requiring payments to or from any officer, director or
such employee or, to the knowledge of the Company, any entity in which any officer, director, or any such employee has a substantial interest or is an officer, director, trustee or partner, in each case as would be required to be disclosed pursuant
to the requirements of Item 404 of Regulation S-K. 
 (aa) Neither the Company nor, to the knowledge of the
Company, any other Person acting for or on behalf of the Company including, without limitation, any director, officer, agent or employee of the Company or any of its subsidiaries, has, directly or indirectly, while acting on behalf of the Company or
any of its subsidiaries (i) used any corporate funds for unlawful contributions, gifts, entertainment or other unlawful expenses, or received or retained any funds, relating to political activity; (ii) made any unlawful payment from
corporate funds to, or received or retained any unlawful funds from, foreign or domestic government officials or employees or to or from foreign or domestic political parties or campaigns; (iii) violated any provision of the Foreign Corrupt
Practices Act of 1977, as amended; or (iv) made any other unlawful payment or received or retained any other unlawful funds. 
 (bb) The operations of the Company and its subsidiaries are and have been conducted at all times in compliance with applicable financial recordkeeping and reporting requirements of the Currency and
Foreign Transactions Reporting Act of 1970, as amended, the money laundering statutes of all jurisdictions, the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any
governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or any of its subsidiaries
with respect to the Money Laundering Laws is pending or, to the knowledge of the Company, threatened, except, in each case, as would not reasonably be expected to have a Material Adverse Effect. 

(cc) At the time of filing of the Registration Statement, which is its most recent shelf registration statement, and at
the time of any amendment thereto, the Company was not, and the Company on the date of this Agreement is not, an “ineligible issuer” as defined in Rule 405 under the Securities Act. 

(dd) Without the prior consent of C. K. Cooper & Company, Inc., as placement agent for the Offering (the
“Placement Agent”), the Company has not made and will not make any offer relating to the Units (or any securities comprising the Units) that would constitute a “free writing prospectus” as defined in Rule 405 under the
Securities Act. 
 (ee) Except as set forth in the Prospectus, neither the Company, nor any director or officer
thereof, is or has been the subject of any action involving a claim of violation of or liability under federal or state securities laws or a claim of breach of fiduciary duty, or any criminal statute during the term of such director or
officer’s tenure with the Company, 

  
 16 

 
nor, to the knowledge of the Company, prior to such tenure that is of a nature that would be required to be disclosed pursuant to Item 103 of Regulation S-K with regard to the Company or
Item 401 of Regulation S-K with regard to the Company’s officers or directors. There has not been, and to the knowledge of the Company, there is not pending or contemplated, any investigation by the Commission involving the Company, other
than routine reviews of the Company’s Commission filings which are not currently pending with respect to the Prospectus or the Registration Statement. The Commission has not issued any stop order or other order suspending the effectiveness of
any registration statement filed by the Company under the Exchange Act or the Securities Act. 
 (ff) Any
statistical, industry-related or market-related data included or incorporated by reference in the Registration Statement are based on or derived from sources that the Company reasonably and in good faith believes to be reliable and accurate, and
such data agree with the sources from which they are derived. 
 (gg) Neither the Company nor, to the knowledge
of the Company, any director, officer, agent, employee or affiliate of the Company or any of its subsidiaries is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department
(“OFAC”); and the Company will not directly or indirectly use the proceeds of the offering, or lend, contribute or otherwise make available such proceeds to any affiliate, joint venture partner or other person or entity, which, to
the Company’s knowledge, will use such proceeds for the purpose of financing the activities of any person currently subject to any U.S. sanctions administered by OFAC. 

(hh) Other than fees due under the Placement Agency Agreement entered into on the date hereof with the Placement Agent
(the “Placement Agency Agreement”), neither the Company nor any of its subsidiaries is a party to any contract, agreement or understanding with any Person that would give rise to a valid claim against the Company or the Placement
Agent for a brokerage commission, finder’s fee or like payment in connection with the offering and sale of the Units. 
 (ii) The Company is not an “investment company” or an “affiliated person” of, or “promoter” or “principal underwriter” for, an “investment company”, as
such terms are defined in the Investment Company Act of 1940, as amended (the “Investment Company Act”). 
 (jj) To the knowledge of the Company, there are no affiliations or associations between (i) any member of the Financial Industry Regulatory Authority (“FINRA”) and (ii) the
Company or any of the Company’s officers, directors or 5% or greater securityholders or any beneficial owner of the Company’s unregistered equity securities that were acquired at any time on or after the one hundred eightieth
(180th) day immediately preceding the date the Registration Statement was initially filed with the Commission, except as has been disclosed to the Placement Agent. The Company will inform the Purchaser if it becomes aware that any officer,
director or stockholder of the Company is or becomes an affiliate or associated person of a FINRA member participating in the transactions contemplated by this Agreement. 

(kk) The Company has not, and to its knowledge no one acting on its behalf has, (i) taken, directly or indirectly,
any action designed to cause or to result in the stabilization 

  
 17 

 
or manipulation of the price of any security of the Company to facilitate the sale or resale of any of the Units or the securities comprising the Units, (ii) sold, bid for, purchased, or,
paid any compensation for soliciting purchases of, any of the Units or the securities comprising the Units (other than for the Placement Agent’s placement of the Units), or (iii) paid or agreed to pay to any Person any compensation for
soliciting another to purchase any other securities of the Company. 
 The Purchaser acknowledges and agrees that the Company
does not make and has not made any representations or warranties with respect to the transactions contemplated hereby other than the Registration Statement, the Prospectus, and those representations and warranties specifically set forth in this
Agreement. 
 3.2 Representations and Warranties of the Purchaser. The Purchaser hereby represents and warrants to the
Company as follows: 
 (a) The Purchaser is either an individual or an entity duly organized, validly existing
and in good standing under the laws of the jurisdiction of its organization with full right, corporate, partnership or limited liability company power and authority to enter into and to consummate the transactions contemplated by this Agreement and
otherwise to carry out its obligations hereunder. The execution and delivery of this Agreement and performance by the Purchaser of the transactions contemplated by this Agreement have been duly authorized by all necessary corporate, partnership,
limited liability company or similar action, as applicable, on the part of the Purchaser. This Agreement has been duly executed by the Purchaser, and when delivered by the Purchaser in accordance with the terms hereof, will constitute the valid and
legally binding obligation of the Purchaser, enforceable against it in accordance with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general
application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and
contribution provisions may be limited by applicable law. 
 (b) The execution, delivery and performance by the
Purchaser of the Agreement and the consummation by it of the transactions contemplated hereby do not and will not (i) conflict with or violate any provision of the Purchaser’s certificate of incorporation, bylaws or other organizational or
charter documents, or (ii) conflict with or result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Purchaser is subject (including federal
and state securities laws and regulations), or by which any property or asset of the Purchaser is bound or affected. 
 (c) The Purchaser is acquiring the Units as principal for its own account and not with a view to or for distributing or reselling such Units or any part thereof in violation of the Securities Act or any
applicable state securities law, has no present intention of distributing any of such Units in violation of the Securities Act or any applicable state securities law and has no direct or indirect arrangement or understandings with any other persons
to distribute or regarding the distribution of such Units in violation of the Securities Act or any applicable state securities law (this representation and warranty not limiting the Purchaser’s right to sell the Units or any part thereof in
compliance with applicable federal and state securities laws). The Purchaser is acquiring the Units hereunder in the ordinary course of its business. 

  
 18 

 (d) Other than consummating the transactions contemplated hereunder, the
Purchaser has not, nor has any Person acting on behalf of or pursuant to any understanding with the Purchaser, directly or indirectly executed any purchases or sales, including Short Sales, of the securities of the Company during the period
commencing as of the time that the Purchaser first became aware of the proposed transactions contemplated hereunder and ending immediately prior to the execution hereof. Notwithstanding the foregoing, in the case of a Purchaser that is a
multi-managed investment vehicle whereby separate portfolio managers manage separate portions of the Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing
other portions of the Purchaser’s assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Units covered by this
Agreement. Other than to other Persons party to this Agreement and its Affiliates and their respective investment advisors, agents, counsel and other advisors, the Purchaser has maintained the confidentiality of all disclosures made to it in
connection with this transaction (including the existence and terms of this transaction). Notwithstanding the foregoing, for avoidance of doubt, nothing contained herein shall constitute a representation or warranty, or preclude any actions, with
respect to the identification of the availability of, or securing of, available shares to borrow in order to effect Short Sales or similar transactions in the future. 

(e) At the time such Purchaser was offered the Units, it was, and as of the date hereof it is, and on each date on which
it exercises any Warrants, it will be either: (i) an “accredited investor” as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(5), (a)(6), (a)(7) or (a)(8) under the Securities Act or (ii) a “qualified institutional
buyer” as defined in Rule 144A(a) under the Securities Act. Such Purchaser is not required to be registered as a broker-dealer under Section 15 of the Exchange Act. Such Purchaser, either alone or together with its representatives, has
such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Units and has so evaluated the merits and risks of such investment. Such
Purchaser is able to bear the economic risk of an investment in the Units and, at the present time, is able to afford a complete loss of such investment. 
 (f) Such Purchaser has no present intent to effect a “change of control” of the Company as such term is understood under the rules promulgated pursuant to Section 13(d) of the Exchange Act.

 The Company acknowledges and agrees that the Purchaser does not make or has not made any representations or warranties with
respect to the transactions contemplated hereby other than those specifically set forth in this Section 3.2.

 OTHER AGREEMENTS OF THE PARTIES 
 4.1 Securities Laws Disclosure; Publicity. 
 (a) The Company
shall, by 9:00 a.m. (New York City time) on the Trading Day immediately following the date hereof, issue a press release disclosing the material terms of the transactions contemplated hereby. The Company shall, by 5:00 p.m. (New York City time) on
the fourth Trading Day immediately following the date hereof, file a Current Report on Form 8-K disclosing the material terms of the transactions contemplated hereby 

  
 19 

 
and including the form of this Agreement as an exhibit thereto. From and after the issuance of such press release and Form 8-K, the Company shall have publicly disclosed all material, non-public
information delivered to the Purchaser 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 this Agreement. The Company and the Purchaser
shall consult with each other in issuing any other press releases with respect to the transactions contemplated hereby, and neither the Company nor the Purchaser shall issue any such press release nor otherwise make any such public statement without
the prior consent of the Company, with respect to any press release of the Purchaser, or without the prior consent of the Purchaser, with respect to any press release of the Company, which consent shall not unreasonably be withheld or delayed,
except if such disclosure is required by law, in which case the disclosing party shall promptly provide the other party with prior notice of such public statement or communication. 

(b) Except as may be required pursuant to Item 404 of Regulation S-K, the Company shall not identify the Purchaser by
name in any press release or public filing, or otherwise publicly disclose the Purchaser’s name, without the Purchaser’s prior written consent, unless required by law or the rules and regulations of an applicable securities exchange,
provided, however, that promptly after becoming aware of any request or requirement to so disclose (a “Disclosure Requirement”), and in any event prior to any such disclosure, the Company will provide the Purchaser with
notice of such request or requirement so that the Purchaser may at its election seek a protective order or other appropriate remedy and the Company will fully cooperate with the Purchaser’s efforts to obtain the same; provided, further,
however, if, absent the entry of such a protective order or other remedy, the Company is compelled by applicable law, rule or regulation or a court order, subpoena, similar judicial process, regulatory agency or stock exchange rule to disclose
the Purchaser’s name, the Company may disclose only that portion of such information that the Company is so compelled to disclose and will use its reasonable best efforts to obtain assurance that confidential treatment will be accorded to that
portion of such information that is being disclosed. As of the date hereof, the Company is not aware of any Disclosure Requirement. 
 4.2 Non-Public Information. Except with respect to the material terms and conditions of the transactions contemplated by this Agreement which will subsequently become public information in
accordance with Section 4.1, or upon the filing of the Prospectus, the Company covenants and agrees that neither it, nor any other Person acting on its behalf, will provide the Purchaser or its agents or counsel with any information that
the Company believes constitutes material non-public information, unless prior thereto the Purchaser shall have executed a written agreement with the Company regarding the confidentiality and use of such information. The Company understands and
confirms that the Purchaser shall be relying on the foregoing covenant in effecting transactions in securities of the Company. 

4.3 Use of Proceeds. Except as set forth in the Prospectus, the Company shall use the net proceeds from the sale of the Units
hereunder for working capital purposes. 
 4.4 Indemnification of Purchaser. Subject to the provisions of this
Section 4.4 and to the extent permitted by law, the Company will indemnify and hold the Purchaser, its Affiliates, and their respective directors, managers, officers, shareholders, members, partners, employees and agents (and any other
Persons with a functionally equivalent role of a Person holding such titles notwithstanding 

  
 20 

 
a lack of such title or any other title), each Person who controls the Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, managers, officers, shareholders, agents, members, partners, employees and agents (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title) of such
controlling persons (each, a “Purchaser Party”) harmless from any and all losses, liabilities, obligations, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable
attorneys’ fees and costs of investigation (“Damages”) that any Purchaser Party may suffer or incur due to a claim by a third party as a result of or relating to (a) any breach of any of the representations, warranties,
covenants or agreements made by the Company in this Agreement or (b) any action instituted against a Purchaser in any capacity, or any of them or their respective Affiliates, by any shareholder of the Company who is not an Affiliate of the
Purchaser, with respect to any of the transactions contemplated by this Agreement (except to the extent such Damages are based upon a breach of the Purchaser’s representations, warranties or covenants under this Agreement or any agreements or
understandings the Purchaser may have with any such shareholder or any violations by the Purchaser of state or federal securities laws or any conduct by the Purchaser which constitutes fraud, gross negligence, willful misconduct or malfeasance). If
any action shall be brought against the Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, the Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right to assume the
defense thereof with counsel of its own choosing reasonably acceptable to the Purchaser Party. The Purchaser Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses
of such counsel shall be at the expense of the Purchaser Party except to the extent that (i) the employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time
to assume such defense and to employ counsel or (iii) in such action there is, in the reasonable opinion of counsel, a material conflict on any material issue between the position of the Company and the position of the Purchaser Party, in which
case the Company shall be responsible for the reasonable fees and expenses of no more than one such separate counsel (together with any necessary local counsel). The Company will not be liable to the Purchaser Party under this Agreement (y) for
any settlement by a Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (z) to the extent, but only to the extent that a loss, claim, damage or liability is
attributable to the Purchaser Party’s breach of any of the representations, warranties, covenants or agreements made by the Purchaser Party in this Agreement. The Company will not settle any such claim, action or proceeding without the prior
written consent of the Purchaser Party, which will not be unreasonably withheld or delayed; provided, however, that such consent shall not be required if the settlement includes a full and unconditional release satisfactory to the Purchaser
Party from all liability arising or that may arise out of such claim or proceeding and does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of the Purchaser Party. 

4.5 Reservation of Common Stock. As of the date hereof, the Company has reserved and the Company shall continue to reserve and
keep available at all times, free of any Liens, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue shares of Common Stock issued (i) as part of the Units purchased pursuant to this Agreement and
(ii) upon the exercise of the Warrants issued as part of the Units purchased pursuant to this Agreement. 
 4.6 Listing
of Common Stock. The Company hereby agrees to use reasonable best efforts to maintain the listing of the Common Stock on the Principal Market, and as soon as reasonably practicable (but not later than the Closing Date) to list all of the shares
of Common Stock issued or issuable as part of the Units or upon exercise of the Warrants on such Principal Market. The 

  
 21 

 
Company further agrees, if the Company applies to have the Common Stock traded on any other securities exchange, it will include in such application all of such shares of Common Stock, and will
take such other action as is necessary to cause all of such shares of Common Stock to be listed on such other securities exchange as promptly as possible. The Company will take all action reasonably necessary to continue the listing and trading of
its Common Stock on such securities exchange and will comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of such securities exchange. 

4.7 Equal Treatment of Purchaser. The sale and purchase of the Units under this Agreement is, and shall be, on the same terms and
conditions offered all other purchasers of the Units in the Offering. If the Company offers better terms to any other purchaser of Units in the Offering than are being offered to the Purchaser under this Agreement, including, without limitation, by
amendment or modification to this Agreement or otherwise, then the Company shall afford Purchaser offer to sell the Units to the Purchaser on the same terms. 
 4.8 Certain Transactions and Confidentiality. The Purchaser covenants that neither it nor any Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or
sales, including Short Sales, of any of the Company’s securities during the period commencing with the execution of this Agreement and ending at such time that the transactions contemplated by this Agreement are first publicly announced
pursuant to the initial press release as described in Section 4.1. The Purchaser covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company pursuant to the initial press
release as described in Section 4.1, the Purchaser will maintain the confidentiality of the existence and terms of this transaction. Notwithstanding the foregoing and notwithstanding anything contained in this Agreement to the
contrary, the Company expressly acknowledges and agrees that (i) no Purchaser makes any representation, warranty or covenant hereby that it will not engage in effecting transactions in any securities of the Company after the time that the
transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in Section 4.1, (ii) no Purchaser shall be restricted or prohibited from effecting any transactions in any
securities of the Company in accordance with applicable securities laws from and after the time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in
Section 4.1 and (iii) no Purchaser shall have any duty of confidentiality to the Company or its subsidiaries after the issuance of the initial press release as described in Section 4.1. Notwithstanding the foregoing, in
the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of the Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by
the portfolio managers managing other portions of the Purchaser’s assets, the covenants and agreements set forth in the first two sentences of this Section 4.8 shall only apply with respect to the portion of assets managed by the
portfolio manager that made the investment decision to purchase the Securities covered by this Agreement. 
 4.9 Subsequent
Equity Sales. From the date hereof through the 90 day anniversary of the Closing Date, the Company will not, directly or indirectly, offer, sell, grant any option to purchase, or otherwise dispose of (or announce any offer, sale, grant or any
option to purchase or other disposition of) any of its Common Stock or Common Stock Equivalents. Notwithstanding the foregoing, in no event shall this Section 4.9 prohibit the Company from issuing Excluded Securities.

requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right. 
 5.6 Headings. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. 

5.7 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and

assets). The Purchaser may assign any or all of its rights under this Agreement to any Person to whom the Purchaser assigns or transfers any Units (or securities comprising the Units), provided that such transferee agrees in writing to be bound,

governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations,
enforcement and defense of the transactions contemplated by this Agreement (whether brought against a party hereto or its respective Affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively in the state and
federal courts sitting in the City of New York, Borough of Manhattan. 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 improper or is an inconvenient venue for such proceeding. 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 via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for 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 other manner permitted by law. If either party shall commence an action or
proceeding to enforce any provisions of this Agreement, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its reasonable attorneys’ fees and other costs and expenses incurred with the
investigation, preparation and prosecution of such action or proceeding. 
 5.10 Execution. This Agreement may be
executed in two or more counterparts, all of which when taken together 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, it being understood
that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature 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 facsimile or “.pdf” signature page were an original thereof. 

5.11 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction
to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto
shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared
to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

 5.12 Replacement of Certificates. If any certificate evidencing the shares of Common
Stock issued or issuable hereunder is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu of and substitution
therefor, a new certificate, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity or security, if requested. The applicant for a new certificate under such
circumstances shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement certificates. 
 5.13 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchaser and the Company will be entitled to
specific performance under this Agreement. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in this Agreement and hereby agree to waive and not to assert
in any action for specific performance of any such obligation the defense that a remedy at law would be adequate. 
 5.14
Construction. The parties agree that each of them and/or their respective counsel has reviewed and had an opportunity to revise this Agreement and, therefore, the normal rule of construction to the effect that any ambiguities are to be
resolved against the drafting party shall not be employed in the interpretation of this Agreement or any amendments hereto. In addition, each and every reference to share prices and shares of Common Stock in this Agreement shall be subject to
adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after the date of this Agreement.
