 4.1 Organization, Good Standing and Qualification. The
Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware. The Company is duly qualified to transact business and is in good standing in each jurisdiction in which the failure to so
qualify would have a Material Adverse Effect (as defined below) on its business or properties. As used in this Agreement, “Material Adverse Effect” means any material adverse effect on the business, properties, assets, liabilities,
operations, results of operations, condition (financial or otherwise) or prospects of the Company and its Subsidiaries, if any, individually or taken as a whole, or on the transactions contemplated hereby or on the Exchange Documents (as defined
below) or by the agreements and instruments to be entered into (or entered into) in connection herewith or therewith, or on the authority or ability of the Company to perform its obligations under this Agreement. 

4.2 Authorization. All corporate action on the part of the Company, its officers, directors and stockholders necessary for the
authorization, execution and delivery of this Agreement and the other Exchange Documents and the performance of all obligations of the Company hereunder and thereunder, and the authorization of all the transactions contemplated by this Agreement,
including, without limitation, the issuance of the New Note and New Warrants, have been taken on or prior to the date hereof. 
 4.3
Valid Issuance of the New Note and New Warrants. The issuance of the New Notes and the New Warrants are duly authorized and, upon issuance in accordance with the terms of the Exchange Documents, the New Conversion Shares and the New Warrant
Shares shall be validly issued, fully paid and non-assessable and free from all preemptive or similar rights, mortgages, defects, claims, liens, pledges, charges, taxes, rights of first refusal, encumbrances, security interests and other
encumbrances (collectively “Liens”) with respect to the issuance thereof. As of the date hereof, the Company has reserved from its duly authorized capital stock not less than 150% of the sum of (i) the maximum number of New
Conversion Shares issuable upon conversion of the New Notes (assuming for purposes hereof that (x) the 

  
 5 








 
New Notes are convertible at the Alternate Conversion Price (as defined in the Notes) assuming a Conversion Date (as defined in the New Note) as of the date hereof, (y) interest on the Notes
shall accrue through the Maturity Date (as defined in the New Note) and will be converted in shares of Common Stock (as defined below) at a conversion price equal to the Alternate Conversion Price assuming a Conversion Date as of the date hereof and
(z) any such conversion shall not take into account any limitations on the conversion of the New Notes set forth in the New Notes), and (ii) the maximum number of New Warrant Shares initially issuable upon exercise of the New Warrants
(without taking into account any limitations on the exercise of the New Warrants set forth therein). Upon issuance or conversion in accordance with the New Notes or exercise in accordance with the New Warrants (as the case may be), the New
Conversion Shares and the New Warrant Shares, respectively, when issued, will be validly issued, fully paid and nonassessable and free from all preemptive or similar rights or Liens with respect to the issue thereof, with the holders being entitled
to all rights accorded to a holder of Common Stock. The offer and issuance by the Company of the New Securities is exempt from registration under the 1933 Act. Each of the New Securities will be freely tradable and (in the case of the New Warrant
Shares, assuming a cashless exercise of the New Warrants) shall not be required to bear, and shall not bear, any 1933 Act or other restrictive legend. 

4.4 Offering. Neither the Company, nor any of its affiliates, nor any Person acting on its or their behalf, has engaged in any form of
general solicitation or general advertising (within the meaning of Regulation D) in connection with the offer or sale of the New Securities. The Company shall be responsible for the payment of any placement agent’s fees, financial advisory
fees, or brokers’ commissions (other than for persons engaged by the Investor or its investment advisor) relating to or arising out of the transactions contemplated hereby. The Company shall pay, and hold the Investor harmless against, any
liability, loss or expense (including, without limitation, attorney’s fees and out-of-pocket expenses) arising in connection with any such claim. Neither the Company nor any of its Subsidiaries has engaged any placement agent or other agent in
connection with the Exchange and the issuance of the New Securities. The offer, exchange and issuance, as applicable, of the New Securities as contemplated by this Agreement are exempt from the registration requirements of the 1933 Act and the
qualification or registration requirements of state securities laws or other applicable blue sky laws. Neither the Company nor any authorized agent acting on its behalf will take any action hereafter that would cause the loss of such exemptions.

 4.5 Compliance With Laws. The Company has not violated any law or any governmental regulation or requirement which violation has
had or would reasonably be expected to have a Material Adverse Effect, and the Company has not received written notice of any such violation. 

4.6 Consents; Waivers. No consent, waiver, approval or authority of any nature, or other formal action, by any Person, not already
obtained, is required in connection with the execution and delivery of this Agreement by the Company or the consummation by the Company of the transactions provided for herein and therein.

will not (i) result in a violation of the organizational documents of the Company or (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any
rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which the Company is a party or by which it is bound, or (iii) result in a 

  
 7 








 
violation of any law, rule, regulation, order, judgment or decree (including federal and state securities or “blue sky” laws) applicable to the Company, except in the case of clause
(ii) above, for such conflicts, defaults or rights which would not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect. 

4.11 Disclosure. Other than as set forth in the 8-K Filing (as defined below), the Company confirms that neither it nor any other
Person acting on its behalf has provided the Investor or its agents or counsel with any information that constitutes or could reasonably be expected to constitute material, nonpublic information. The Company understands and confirms that the

that all of such Liens and all Collateral (as defined in the Security Agreement) heretofore pledged as security for such Obligations, continue to be and remain collateral for such Obligations from and after the date hereof. For the avoidance of
doubt, each Transaction Document remains in full force and effect. The Company hereby acknowledges that the New Note and New Warrants are not in any way intended to impair or affect the Liens granted, pledged or assigned by the Company to the
Collateral Agent for the holders of the Notes in accordance with the terms of the Security Documents.

Conversion Shares against the Installment Amount (as defined in the Investor Note) due on a future Installment Date and the Investor shall instead be entitled to keep such excess Pre-Installment Conversion Shares as additional interest thereunder.

 7.7 Severability. If one or more provisions of this Agreement are held to be unenforceable
under applicable law, such provision shall be excluded from this Agreement and the balance of the Agreement shall be interpreted as if such provision were so excluded and shall be enforceable in accordance with its terms 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). 

7.8 Entire Agreement . This Agreement together with the other Exchange Documents, represents the entire agreement and understandings
between the parties concerning the Exchange and the other matters described herein and therein and supersedes and replaces any and all prior agreements and understandings solely with respect to the subject matter hereof and thereof. Except as
expressly set forth herein, nothing herein shall amend, modify or waive any term or condition of the other Exchange Documents. 
 7.9
Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 

7.10 Interpretation. Unless the context of this Agreement clearly requires otherwise, (a) references to the plural include the
singular, the singular the plural, the part the whole, (b) references to any gender include all genders, (c) “including” has the inclusive meaning frequently identified with the phrase “but not limited to” and
(d) references to “hereunder” or “herein” relate to this Agreement. 
 7.11 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. 

7.12 Survival. The representations, warranties and covenants of the Company and the Investor contained herein shall survive the Closing
and delivery of the New Note and New Warrants. 
 7.13 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.

 7.14 No Strict 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. 

7.15 Independent Nature of Investor’s Obligations and Rights. The obligations of the Investor under this Agreement are several and
not joint with the obligations of any Other Investor, and the Investor shall not be responsible in any way for the performance of the obligations of any Other Investor under any Other Agreement. Nothing contained herein or in any Other Agreement,
and no action taken by the Investor pursuant hereto, shall be deemed to constitute the Investor and Other Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investor and Other
Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement or any Other Agreement and the Company acknowledges that, to the best of its knowledge, the Investor and the
Other Investors are not acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement or any Other Agreement. The Company and the Investor confirm that the Investor has independently participated
in the negotiation of the transactions contemplated hereby with the advice of its own counsel and advisors. The Investor shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this
Agreement, and it shall not be necessary for any Other Investor to be joined as an additional party in any proceeding for such purpose. 

7.16 Equal Treatment Acknowledgement; Most Favored Nations. The parties hereto herby acknowledge and agree that, in accordance with
Section 9(e) of the Securities Purchase Agreement, the Company is obligated to present the terms of this offering to each Other Investor; provided that each Other Agreement shall be negotiated separately with each Other Investor and shall not
in any way be construed as the Investor or any Other Investor acting in concert or as a group with respect to the purchase, disposition or voting of securities of the Company or otherwise. The Company hereby represents and warrants as of the date
hereof and covenants and agrees that none of the terms offered to any Person with respect to the Exchange, including, without limitation with respect to any consent, release, amendment, settlement, or waiver relating to any Exchange (each an
“Settlement Document”), is or will be more favorable to such Person (other than any reimbursement of legal fees) than those of the Investor and this Agreement. If, and whenever on or after the date hereof, the Company enters into a
Settlement Document, then (i) the Company shall provide notice thereof to the Investor immediately following the occurrence thereof and (ii) the terms and conditions of this Agreement shall be, without any further action by the Investor or
the Company, automatically amended and modified in an economically and legally equivalent manner such that the Investor shall receive the benefit of the more favorable terms and/or conditions (as the case may be) set forth in such Settlement
Document, provided that upon written notice to the Company at any time the Investor may elect not to accept the benefit of any such amended or modified term or condition, in which event the term or condition contained in this Agreement shall apply
to the Investor as it was in effect immediately prior to such amendment or modification as if such amendment or modification never occurred with respect to the Investor. The provisions of this Section 6.16 shall apply similarly and equally to
each Settlement Document.
