Subsidiaries is bound or subject. Except for the issuance of the Shares and Warrants contemplated by this Agreement, 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 that has not been publicly disclosed at least one
(1) Trading Day prior to the date that this representation is made. 
 (k) Litigation. There is no Action which
(i) adversely affects or challenges the legality, validity or enforceability of any of the Transaction Documents or the issuance of the Securities or (ii) except as specifically disclosed in the SEC Reports, would, if there were an

executive officer of the Company (as defined in Rule 501(f) of the Securities Act) has notified the Company or any such Subsidiary that such officer intends to leave the Company or any such Subsidiary or otherwise terminate such officer’s
employment with the Company or any such Subsidiary. To the Company’s Knowledge, no executive officer is, or is now expected to be, in violation of any term of any material term of any employment contract, confidentiality, disclosure or
proprietary information agreement or non-competition agreement, or any other contract or agreement or any restrictive covenant in favor of a third party, and to the Company’s Knowledge, the continued employment of each such executive officer
does not subject the Company or any Subsidiary to any liability with respect to any of the foregoing matters. The Company and its Subsidiaries are in compliance with all U.S. federal, state, local and foreign laws and regulations relating to
employment and employment practices, terms and conditions of employment and wages and hours, except where the failure to be in compliance would not, individually or in the aggregate, have or reasonably be expected to result in a Material Adverse
Effect. 
 (m) Compliance. Neither the Company nor any of its Subsidiaries (i) is in default under or in violation
of (and no event has occurred that has not been waived that, with notice or lapse of time or both, would result in a default by the Company or any of its Subsidiaries under), nor has the Company or any of its Subsidiaries received written notice of
a claim that it is in default under or that it is in violation of, any Material Contract (whether or not such default or violation has been waived), (ii) is in violation of any order of any court, arbitrator or governmental body having
jurisdiction over the Company, its Subsidiaries or their respective properties or assets, or (iii) is in violation of, or in receipt of written notice that it is in violation of, any statute, rule or regulation of any governmental authority or
self-regulatory organization (including the Principal Trading Market) applicable to the Company, except in each case as would not, individually or in the aggregate, have or reasonably be expected to result in a Material Adverse Effect. 

(n) Regulatory Permits. The Company and each of its Subsidiaries possess all certificates, authorizations and permits issued by
the appropriate federal, state, local or foreign regulatory authorities necessary to conduct its respective business as currently conducted and as described in the SEC Reports, except where the failure to possess such permits, individually or in the
aggregate, has not and would not have or reasonably be expected to result in a Material Adverse Effect (“Material Permits”), and neither the Company nor any of its Subsidiaries has received any notice of Proceedings relating to the
revocation or material adverse modification of any such Material Permits. 
 (o) Title to Assets. The Company and its
Subsidiaries have good and marketable title in fee simple to all real property owned by them. The Company and its Subsidiaries have good and marketable title to all tangible personal property owned by them that is material to the business of the
Company and its Subsidiaries, taken as whole, in each case free and clear of all Liens except such as do not materially affect the value of such property and do not interfere with the use made and proposed to be made of such property by the Company
and 

  
 13 

 
any of its Subsidiaries. Any real property and facilities held under lease by the Company and any of its Subsidiaries are held by them under valid, subsisting and enforceable leases with such
exceptions as are not material and do not interfere with the use made and proposed to be made of such property and facilities by the Company and its Subsidiaries. 
 (p) Patents and Trademarks. To the Company’s Knowledge, the Company and the Subsidiaries own, possess, license or have other rights to use, all patents, patent applications, trade and service
marks, trade and service mark applications and registrations, trade names, trade secrets, inventions, copyrights, licenses, technology, know-how and other intellectual property rights and similar rights described in the SEC Reports as necessary or
material for use in connection with their respective businesses and which the failure to so have would have or reasonably be expected to result in a Material Adverse Effect (collectively, the “Intellectual Property Rights”). Neither
the Company nor any Subsidiary has received a notice (written or otherwise) that any of the Intellectual Property Rights used by the Company or any Subsidiary violates or infringes upon the rights of any Person. There is no pending or, to the
Company’s Knowledge, threatened action, suit, proceeding or claim by any Person that the Company’s business as now conducted infringes or otherwise violates any patent, trademark, copyright, trade secret or other proprietary rights of
another. To the Company’s Knowledge, there is no existing infringement by another Person of any of the Intellectual Property Rights that would have or would reasonably be expected to have a Material Adverse Effect. The Company and its
Subsidiaries have taken reasonable security measures to protect the secrecy, confidentiality and value of all of their Intellectual Property Rights, except where failure to do so could not, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect. 
 (q) Insurance. The Company and each of the Subsidiaries are insured by insurers of
recognized financial responsibility against such losses and risks and in such amounts as the Company believes to be prudent and customary in the businesses and locations in which the Company and the Subsidiaries are engaged, including, but not
limited to, directors and officers insurance coverage. Neither the Company nor any of its Subsidiaries has received any notice of cancellation of any such insurance, nor, to the Company’s Knowledge, will it or any Subsidiary be unable to renew
their respective 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 without a significant increase in cost. 

(r) Transactions With Affiliates and Employees. Except as set forth in the SEC Reports, none of the officers or directors of the
Company and, to the Company’s Knowledge, none of the employees of the Company is presently a party to any transaction (or to a presently contemplated transaction) with the Company or any Subsidiary (other than for services as employees,
officers and directors), that would be required to be disclosed pursuant to Item 404 of Regulation S-K promulgated under the Securities Act. 
 (s) Internal Accounting Controls. 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 GAAP and to maintain asset and liability accountability, (iii) access
to assets or incurrence of liabilities is permitted only in accordance with management’s general or specific authorization, and (iv) the 

  
 14 

 
recorded accountability for assets and liabilities is compared with the existing assets and liabilities at reasonable intervals and appropriate action is taken with respect to any differences.

 (t) Sarbanes-Oxley; Disclosure Controls. The Company is in compliance in all material respects with all of the
provisions of the Sarbanes-Oxley Act of 2002 which are applicable to it as of the Closing Date. The Company has established disclosure controls and procedures (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) for the
Company and designed such disclosure controls and procedures to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the
time periods specified in the Commission’s rules and forms. The Company’s certifying officers have evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end of the period covered by the
Company’s most recently filed periodic report under the Exchange Act (such date, the “Evaluation Date”). The Company presented in its most recently filed periodic report under the Exchange Act the conclusions of the certifying
officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no changes in the Company’s internal control over financial reporting
(as such term is defined in the Exchange Act) that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. 

(u) Certain Fees. No person or entity will have, as a result of the transactions contemplated by this Agreement, any valid right,
interest or claim against or upon the Company or a Purchaser for any commission, fee or other compensation pursuant to any agreement, arrangement or understanding entered into by or on behalf of the Company, other than the Placement Agents with
respect to the offer and sale of the Shares and Warrants (which placement agent fees are being paid by the Company). The Company shall indemnify, pay, and hold each Purchaser harmless against, any liability, loss or expense (including, without
limitation, attorneys’ fees and out-of-pocket expenses) arising in connection with any such right, interest or claim. 

(v) Private Placement. Assuming the accuracy of the Purchasers’ representations and warranties set forth in
Section 3.2 of this Agreement and the accuracy of the information disclosed in the Accredited Investor Questionnaires provided by the Purchasers, no registration under the Securities Act is required for the offer and sale of the
Securities by the Company to the Purchasers under the Transaction Documents. The issuance and sale of the Securities hereunder does not contravene the rules and regulations of the Principal Trading Market. 

(w) Investment Company. The Company is not, and immediately after receipt of payment for the Shares and Warrants, will not be or
be an “investment company” within the meaning of the Investment Company Act of 1940, as amended. The Company shall conduct its business in a manner so that it will not become subject to the Investment Company Act of 1940, as amended.

maintenance requirements of the Principal Trading Market on the date hereof.

Rights Agreements. The Company has not adopted any stockholder rights plan or similar arrangement relating to accumulations of beneficial ownership of Common Stock or a change in control of the Company. The Company and the Board of Directors
have taken all necessary action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar anti takeover provision under the
Company’s charter documents or the laws of its state of incorporation that is or could reasonably be expected to become applicable to any of the Purchasers as a result of the Purchasers and the Company fulfilling their obligations or exercising
their rights under the Transaction Documents, including, without limitation, the Company’s issuance of the Securities and the Purchasers’ ownership of the Securities. 

(aa) Disclosure. The Company confirms that it has not provided, and to the Company’s Knowledge, none of its officers or
directors nor any other Person acting on its or their behalf has provided, and it has not authorized the Placement Agents to provide, any Purchaser or its respective agents or counsel with any information that it believes constitutes material,
non-public information except insofar as the existence, provisions and terms of the Transaction Documents and the proposed transactions hereunder may constitute such information, all of which will be disclosed by the Company in the Press Release as
contemplated by Section 4.5 hereof. The Company understands and confirms that the Purchasers will rely on the foregoing representations in effecting transactions in securities of the Company.

the offer and sale by the Company of the Securities as contemplated hereby or (ii) cause the offering of the Securities pursuant to the Transaction Documents to be integrated with prior offerings by the Company for purposes of any applicable

and (iii) has set aside on its books provisions reasonably adequate for the payment of all taxes for periods subsequent to the periods to which such returns, reports or declarations apply, except, in the case of clauses (i) and
(ii) above, where the failure to so pay or file any such tax, assessment, charge or return would not have or reasonably be expected to result in a Material Adverse Effect. There are no unpaid taxes in any material amount claimed to be due by
the Company or any of its Subsidiaries by the taxing authority of any jurisdiction.

Company’s Knowledge, neither the Company nor any of its Subsidiaries (i) is in violation of any statute, rule, regulation, decision or order of any governmental agency or body or any court, domestic or foreign, relating to the use,

Purchasers is acting solely in the capacity of an arm’s length purchaser with respect to the Transaction Documents and the transactions

warrants as of the date hereof and as of the Closing Date to the Company and the Placement Agents as follows: 
 (a)
Organization; Authority. Such Purchaser is an entity duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization with the requisite corporate or partnership power and authority to enter into
and to consummate the transactions contemplated by the applicable Transaction Documents and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of this Agreement by such Purchaser and performance by such
Purchaser of the transactions contemplated by this Agreement have been duly authorized by all necessary corporate or, if such Purchaser is not a corporation, such partnership, limited liability company or other applicable like action, on the part of
such Purchaser. Each Transaction document to which it is a party has been duly executed by such Purchaser, and when delivered by such Purchaser in accordance with the terms hereof, will constitute the valid and legally binding obligation of such
Purchaser, enforceable against it in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to, or

  
 19 

 
affecting generally the enforcement of, creditors’ rights and remedies or by other equitable principles of general application. 

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

(c) Investment Intent. Such Purchaser understands that the Securities are “restricted securities” and have not been
registered under the Securities Act or any applicable state securities law and is acquiring the Shares and Warrants and, upon exercise of the Warrants, will acquire the Warrant Shares issuable upon exercise thereof as principal for its own account
and not with a view to, or for distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable state securities laws, provided, however, that by making the representations herein, such
Purchaser does not agree to hold any of the Securities for any minimum period of time and reserves the right, subject to the provisions of this Agreement and the Registration Rights Agreement, at all times to sell or otherwise dispose of all or any
part of such Securities pursuant to an effective registration statement under the Securities Act or under an exemption from such registration and in compliance with applicable federal and state securities laws. Such Purchaser is acquiring the
Securities hereunder in the ordinary course of its business. Such Purchaser does not presently have any agreement, plan or understanding, directly or indirectly, with any Person to distribute or effect any distribution of any of the Securities (or
any securities which are derivatives thereof) to or through any person or entity; such Purchaser is not a registered broker-dealer under Section 15 of the Exchange Act or an entity engaged in a business that would require it to be so registered
as a broker-dealer. 
 (d) Purchaser Status. At the time such Purchaser was offered the Shares and Warrants, it was, and
at the date hereof it is, and on each date on which it exercises the Warrants it will be, an “accredited investor” as defined in Rule 501(a) under the Securities Act. 

(e) General Solicitation. Such Purchaser is not purchasing the Securities as a result of any advertisement, article, notice or
other communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general advertisement. 

(f) Experience of Such Purchaser. 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 Securities, and has so evaluated the merits and risks of such investment. Such

  
 20 

 
Purchaser is able to bear the economic risk of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment. 

(g) Access to Information. Such Purchaser acknowledges that it has had the opportunity to review the Disclosure Materials and has
been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Securities and the merits and risks of
investing in the Securities; (ii) access to information about the Company and the Subsidiaries and their respective financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate
its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the
investment. Neither such inquiries nor any other investigation conducted by or on behalf of such Purchaser or its representatives or counsel shall modify, amend or affect such Purchaser’s right to rely on the truth, accuracy and completeness of
the Disclosure Materials and the Company’s representations and warranties contained in the Transaction Documents. Such Purchaser has sought such accounting, legal and tax advice as it has considered necessary to make an informed decision with
respect to its acquisition of the Securities. 
 (h) Certain Trading Activities. Other than with respect to the purchase
of Securities hereunder or pursuant to a transaction in compliance with Rule 10b5-1(c) under the Exchange Act, such Purchaser has not directly or indirectly, nor has any Person acting on behalf of or pursuant to any understanding with such
Purchaser, engaged in any transactions in the securities of the Company (including, without limitation, any Short Sales involving the Company’s securities) since the time that such Purchaser was first contacted by the Company, the Placement
Agents or any other Person regarding the specific investment contemplated hereby. Such Purchaser covenants that neither it nor any Person acting on its behalf or pursuant to any understanding with it will engage in any purchase or sale of securities
of the Company (including Short Sales) prior to the time that the transactions contemplated by this Agreement are first publicly disclosed. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby
separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s
assets, the representation and covenant set forth above shall apply only with respect to the portion of assets managed by the portfolio manager that has knowledge about the financing transaction contemplated by this Agreement. Other than to other
Persons party to this Agreement, such 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. 
 (i) Brokers and Finders. No Person will have, as a result of the transactions
contemplated by this Agreement, any valid right, interest or claim against or upon the Company 

  
 21 

 
or any Purchaser for any commission, fee or other compensation pursuant to any agreement, arrangement or understanding entered into by or on behalf of the Purchaser. 

(j) Independent Investment Decision. Such Purchaser has independently evaluated the merits of its decision to purchase Securities
pursuant to the Transaction Documents, and such Purchaser confirms that it has not relied on the advice of any other Purchaser’s business and/or legal counsel in making such decision. Such Purchaser understands that nothing in this Agreement or
any other materials presented by or on behalf of the Company to the Purchaser in connection with the purchase of the Securities constitutes legal, tax or investment advice. Such Purchaser has consulted such legal, tax and investment advisors as it,
in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Securities. Such Purchaser understands that the Placement Agents have acted solely as the agents of the Company in this placement of the Shares and
Warrants and such Purchaser has not relied on the business or legal advice of the Placement Agents or any of their respective agents, counsel or Affiliates in making its investment decision hereunder, and confirms that none of such Persons has made
any representations or warranties to such Purchaser in connection with the transactions contemplated by the Transaction Documents.

federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and such Purchaser’s compliance with, the representations, warranties, agreements, acknowledgements and understandings of such Purchaser
set forth herein in order to determine the availability of such exemptions and the eligibility of such Purchaser to acquire the Securities. 
 (l) No Governmental Review. Such Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or
endorsement of the Securities or the fairness or suitability of the investment in the Securities nor have such authorities passed upon or endorsed the merits of the offering of the Securities. 

(m) Regulation M. Such Purchaser is aware that the anti-manipulation rules of Regulation M under the Exchange Act may apply to
sales of Common Stock and other activities with respect to the Common Stock by the Purchasers. 
 (n) Residency. Such
Purchaser’s residence (if an individual) or offices in which its investment decision with respect to the Securities was made (if an entity) are located at the address immediately below such Purchaser’s name on its signature page hereto.

 The Company and each of the Purchasers acknowledge and agree that no party to this Agreement has made or makes any representations or
warranties with respect to the transactions contemplated hereby other than those specifically set forth in this Article III and the Transaction Documents.

 ARTICLE IV. 
 OTHER AGREEMENTS OF THE PARTIES 
 4.1 Transfer Restrictions.

 (a) Compliance with Laws. Notwithstanding any other provision of this Article IV, each Purchaser covenants that
the Securities may be disposed of only pursuant to an effective registration statement under, and in compliance with the requirements of, the Securities Act, or pursuant to an available exemption from, or in a transaction not subject to, the
registration requirements of the Securities Act, and in compliance with any applicable state and federal securities laws. In connection with any transfer of the Securities other than (i) pursuant to an effective registration statement,
(ii) to the Company, (iii) pursuant to Rule 144 (provided that the Purchaser provides the Company with reasonable assurances (in the form of seller and, if applicable, broker representation letters) that the securities may be sold
pursuant to such rule) or (iv) in connection with a bona fide pledge as contemplated in Section 4.1(b), the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor and
reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities Act. As
a condition of such transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement and the Registration Rights Agreement and shall have the rights of a Purchaser under this Agreement and the Registration Rights
Agreement with respect to such transferred Securities. 
 (b) Legends. Certificates evidencing the Securities shall bear
any legend as required by the “blue sky” laws of any state and a restrictive legend in substantially the following form, until such time as they are not required under Section 4.1(c): 

NEITHER THESE SECURITIES NOR THE SECURITIES ISSUABLE UPON EXERCISE OF THESE SECURITIES HAVE BEEN REGISTERED] [THESE SECURITIES HAVE NOT
BEEN REGISTERED] UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN
EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OR (B) AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE
SECURITIES LAWS OR BLUE SKY LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY AND ITS TRANSFER AGENT OR (II) UNLESS SOLD PURSUANT TO RULE 144 UNDER THE SECURITIES ACT. NOTWITHSTANDING THE FOREGOING, THE
SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES. 

  
 23 

 The Company acknowledges and agrees that a Purchaser may from time to time pledge, and/or
grant a security interest in, some or all of the legended Securities in connection with applicable securities laws, pursuant to a bona fide margin agreement in compliance with a bona fide margin loan. Such a pledge would not be subject to approval
or consent of the Company and no legal opinion of legal counsel to the pledgee, secured party or pledgor shall be required in connection with the pledge, but such legal opinion shall be required in connection with a subsequent transfer or
foreclosure following default by the Purchaser transferee of the pledge. No notice shall be required of such pledge, but Purchaser’s transferee shall promptly notify the Company of any such subsequent transfer or foreclosure. Each Purchaser
acknowledges that the Company shall not be responsible for any pledges relating to, or the grant of any security interest in, any of the Securities or for any agreement, understanding or arrangement between any Purchaser and its pledgee or secured
party. At the appropriate Purchaser’s expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of Securities may reasonably request in connection with a pledge or transfer of the Securities,
including the preparation and filing of any required prospectus supplement under Rule 424(b)(3) of the Securities Act or other applicable provision of the Securities Act to appropriately amend the list of Selling Stockholders thereunder. Each
Purchaser acknowledges and agrees that, except as otherwise provided in Section 4.1(c), any Securities subject to a pledge or security interest as contemplated by this Section 4.1(b) shall continue to bear the legend set forth in
this Section 4.1(b) and be subject to the restrictions on transfer set forth in Section 4.1(a). 
 (c)
Removal of Legends. The legend set forth in Section 4.1(b) above shall be removed and the Company shall issue a certificate without such legend or any other legend to the holder of the applicable Securities upon which it is
stamped or issue to such holder by electronic delivery at the applicable balance account at the Depository Trust Company (“DTC”), if (i) such Securities are registered for resale under the Securities Act (provided that, if the
Purchaser is selling pursuant to the effective registration statement registering the Securities for resale, the Purchaser agrees to only sell such Securities during such time that such registration statement is effective and not withdrawn or
suspended, and only as permitted by such registration statement), (ii) such Securities are sold or transferred pursuant to Rule 144 (if the transferor is not an Affiliate of the Company), or (iii) such Securities are eligible for sale
under Rule 144, without the requirement for the Company to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable) as to such securities and without volume or manner-of-sale restrictions.
Following the earlier of (i) the Effective Date or (ii) Rule 144 becoming available for the resale of Securities, without the requirement for the Company to be in compliance with the current public information required under Rule 144(c)(1)
(or Rule 144(i)(2), if applicable) as to such securities and without volume or manner-of-sale restrictions, the Company shall cause Company Counsel to issue to the Transfer Agent the legal opinion referred to in the Irrevocable Transfer Agent
Instructions. Any fees (with respect to the Transfer Agent, Company Counsel or otherwise) associated with the issuance of such opinion or the removal of such legend shall be borne by the Company. Following the Effective Date, or at such earlier time
as a legend is no longer required for certain Securities, the Company will no later than three (3) Trading Days following the delivery by a Purchaser (i) to the Transfer Agent (with notice to the Company) of a legended certificate
representing Shares or Warrant Shares (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance and/or transfer) or (ii) to the Company of an Exercise Notice in the manner stated in
the Warrants to effect the exercise of such Warrant in accordance with its terms, and any other documents required by Section 4.1(a), deliver or cause to be 

  
 24 

 
delivered to such Purchaser a certificate representing such Securities that is free from all restrictive and other legends. The Company may not make any notation on its records or give
instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 4.1(c). Certificates for Shares or Warrant Shares subject to legend removal hereunder may be transmitted by the Transfer Agent to the
Purchasers by crediting the account of the Purchaser’s prime broker with DTC as directed by such Purchaser. 
 (d)
Irrevocable Transfer Agent Instructions. The Company shall issue irrevocable instructions to its transfer agent, and any subsequent transfer agent, in the form of Exhibit E attached hereto (the “Irrevocable Transfer Agent
Instructions”). The Company represents and warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 4.1(d) (or instructions that are consistent therewith) will be given by
the Company to its transfer agent in connection with this Agreement, and that the Securities shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement and the other Transaction
Documents and applicable law. The Company acknowledges that a breach by it of its obligations under this Section 4.1(d) will cause irreparable harm to a Purchaser. Accordingly, the Company acknowledges that the remedy at law for a breach
of its obligations under this Section 4.1(d) will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 4.1(d), that a Purchaser shall be entitled, in
addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required.

 (e) Acknowledgement. Each Purchaser hereunder acknowledges its primary responsibilities under the Securities Act and
accordingly will not sell or otherwise transfer the Securities or any interest therein without complying with the requirements of the Securities Act. While the Registration Statement remains effective, each Purchaser hereunder may sell the Shares
and Warrant Shares in accordance with the plan of distribution contained in the Registration Statement and if it does so it will comply therewith and with the related prospectus delivery requirements unless an exemption therefrom is available or
unless the Securities are sold pursuant to Rule 144. Each Purchaser, severally and not jointly with the other Purchasers, agrees that if it is notified by the Company in writing at any time that the Registration Statement registering the resale of
the Shares or the Warrant Shares is not effective or that the prospectus included in such Registration Statement no longer complies with the requirements of Section 10 of the Securities Act, the Purchaser will refrain from selling such Shares
and Warrant Shares until such time as the Purchaser is notified by the Company that such Registration Statement is effective or such prospectus is compliant with Section 10 of the Securities Act, unless such Purchaser is able to, and does, sell
such Shares or Warrant Shares pursuant to an available exemption from the registration requirements of Section 5 of the Securities Act. Both the Company and its Transfer Agent, and their respective directors, officers, employees and agents, may
rely on this Section 4.1(e) and each Purchaser hereunder will indemnify and hold harmless each of such persons from any breaches or violations of this Section 4.1(e). 

(f) Buy-In. If the Company shall fail for any reason or for no reason to issue to a Purchaser unlegended certificates within three
(3) Trading Days of receipt of all documents necessary for the removal of the legend set forth above (the “Deadline Date”), then, 

  
 25 

 
in addition to all other remedies available to such Purchaser, if on or after the Trading Day immediately following such three (3) Trading Day period, such Purchaser purchases (in an open
market transaction or otherwise) shares of Common Stock (or a broker or trading counterparty through which the Purchaser has agreed to sell shares makes such purchase) to deliver in satisfaction of a sale by the holder of shares of Common Stock that
such Purchaser anticipated receiving from the Company without any restrictive legend (a “Buy-In”), then the Company shall, within three (3) Trading Days after such Purchaser’s request and in such Purchaser’s sole
discretion, either (i) pay cash to the Purchaser in an amount equal to such Purchaser’s total purchase price (including reasonable brokerage commissions, if any) for the shares of Common Stock so purchased (the “Buy-In
Price”), at which point the Company’s obligation to deliver such certificate (and to issue such shares of Common Stock) shall terminate, or (ii) promptly honor its obligation to deliver to such Purchaser a certificate or
certificates representing such shares of Common Stock and pay cash to the Purchaser in an amount equal to the excess (if any) of the Buy-In Price over the product of (a) such number of shares of Common Stock, times (b) the Closing Bid
Price per share on the Deadline Date. 
 4.2 Reservation of Common Stock. The Company shall take all action necessary to
at all times have authorized, and reserved for the purpose of issuance from and after the Closing Date, the number of shares of Common Stock issuable upon exercise of the Warrants issued at the Closing (without taking into account any limitations on
exercise of the Warrants set forth in the Warrants). 
 4.3 Furnishing of Information. In order to enable the Purchasers
to sell the Securities under Rule 144, for a period of one year from the Closing, the Company shall make all required filings under Section 15(d) of the Exchange Act and timely file (or obtain extensions in respect thereof and file within the
applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act. During such one year period, if the Company is not required to file reports pursuant to the Exchange Act, it will prepare
and furnish to the Purchasers and make publicly available the information described in Rule 144(c)(2), if the provision of such information will allow the Purchasers to sell the Securities under Rule 144. 

4.4 Integration. The Company shall not, and shall use its commercially reasonable efforts to ensure that no Affiliate of the
Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that will be integrated with the offer or sale of the Securities in a manner that
would require the registration under the Securities Act of the sale of the Securities to the Purchasers, or that will be integrated with the offer or sale of the Securities for purposes of the rules and regulations of any Trading Market such that it
would require stockholder approval prior to the closing of such other transaction unless stockholder approval is obtained before the closing of such subsequent transaction. 
 4.5 Securities Laws Disclosure; Publicity. By 9:00 A.M., New York City time, on the Trading Day immediately following the date hereof, the Company shall issue a press release (the “Press
Release”) reasonably acceptable to the Placement Agents disclosing all material terms of the transactions contemplated hereby. On or before 9:00 A.M., New York City time, on the second (2nd) Trading Day immediately following the
execution of this Agreement, the Company will file a Current Report on Form 8-K with the Commission describing the terms of the Transaction Documents (and including as exhibits to such Current Report on Form 8-K the

  
 26 

 
material Transaction Documents (including, without limitation, this Agreement, the form of Warrant and the Registration Rights Agreement)). Notwithstanding the foregoing, the Company shall not
publicly disclose the name of any Purchaser or any Affiliate or investment adviser of any Purchaser, or include the name of any Purchaser or any Affiliate or investment adviser of any Purchaser in any press release or filing with the Commission
(other than the Registration Statement) or any regulatory agency or Trading Market, without the prior written consent of such Purchaser, except (i) as required by federal securities law in connection with (A) any registration statement
contemplated by the Registration Rights Agreement and (B) the filing of final Transaction Documents (including signature pages thereto) with the Commission and (ii) to the extent such disclosure is required by law, request of the Staff of
the Commission or Trading Market regulations, in which case the Company shall provide the Purchasers with prior written notice of such disclosure permitted under this subclause (ii). From and after the issuance of the Press Release, no Purchaser
shall be in possession of any material, non-public information received from the Company, any Subsidiary or any of their respective officers, directors, employees or agents, that is not disclosed in the Press Release unless a Purchaser shall have
executed a written agreement regarding the confidentiality and use of such information. Each Purchaser, severally and not jointly with the other Purchasers, covenants that until such time as the transactions contemplated by this Agreement are
required to be publicly disclosed by the Company as described in this Section 4.5, such Purchaser will maintain the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of
this transaction). 
 4.6 Shareholder Rights Plan. No claim will be made or enforced by the Company or, with the consent
of the Company, any other Person, that any Purchaser is an “Acquiring Person” under any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or similar anti-takeover plan
or arrangement in effect or hereafter adopted by the Company, or that any Purchaser could be deemed to trigger the provisions of any such plan or arrangement, in either case solely by virtue of receiving Securities under the Transaction Documents or
under any other written agreement between the Company and the Purchasers. 
 4.7 Non-Public Information. Except with
respect to the material terms and conditions of the transactions contemplated by the Transaction Documents, including this Agreement, the Company covenants and agrees that neither it, nor any other Person acting on its behalf, will provide any
Purchaser or its agents or counsel with any information regarding the Company that the Company believes constitutes material non-public information without the express written consent of such Purchaser, unless prior thereto such Purchaser shall have
executed a written agreement regarding the confidentiality and use of such information. The Company understands and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions in securities of the Company.

 4.8 Use of Proceeds. The Company shall use the net proceeds from the sale of the Shares and Warrants hereunder for
working capital and general corporate purposes shall not use such proceeds for: (a) the satisfaction of any portion of the Company’s debt (other than payment of trade payables in the ordinary course of the Company’s business and prior
practices), (b) the redemption of any Common Stock or Common Stock Equivalents or (c) the settlement of any outstanding litigation. 

  
 27 

 4.9 Indemnification of Purchasers. 

(a) In addition to the indemnity provided in the Registration Rights Agreement, the Company will indemnify and hold each Purchaser and
its directors, officers, shareholders, 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), each Person who
controls such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders, agents, members, partners or employees (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, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any such Purchaser Party may suffer or incur 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 in the other Transaction Documents or (b) any action instituted against a Purchaser in any
capacity, or any of them or their respective Affiliates, by any stockholder of the Company who is not an Affiliate of such Purchaser, with respect to any of the transactions contemplated by the Transaction Documents (unless such action is based upon
a breach of such Purchaser’s representations, warranties or covenants under the Transaction Documents or any agreements or understandings such Purchaser may have with any such stockholder or any violations by the Purchaser of state or federal
securities laws or any conduct by such Purchaser which constitutes fraud, gross negligence, willful misconduct or malfeasance). 

(b) Promptly after receipt by any Person (the “Indemnified Person”) of notice of any demand, claim or circumstances
which would or might give rise to a claim or the commencement of any action, proceeding or investigation in respect of which indemnity may be sought pursuant to this Section 4.9, such Indemnified Person shall promptly notify the Company
in writing and the Company shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Person, and shall assume the payment of all fees and expenses; provided, however, that the failure of any
Indemnified Person so to notify the Company shall not relieve the Company of its obligations hereunder except to the extent that the Company is actually and materially prejudiced by such failure to notify. In any such proceeding, any Indemnified
Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless: (i) the Company and the Indemnified Person shall have mutually agreed to the retention
of such counsel; (ii) the Company shall have failed promptly to assume the defense of such proceeding and to employ counsel reasonably satisfactory to such Indemnified Person in such proceeding; or (iii) in the reasonable judgment of
counsel to such Indemnified Person, representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. The Company shall not be liable for any settlement of any proceeding effected
without its written consent, which consent shall not be unreasonably withheld, delayed or conditioned. Without the prior written consent of the Indemnified Person, which consent shall not be unreasonably withheld, delayed or conditioned, the Company
shall not effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party,

  
 28 

 
unless such settlement includes an unconditional release of such Indemnified Person from all liability arising out of such proceeding. 

4.10 Principal Trading Market Listing. In the time and manner required by the Principal Trading Market, the Company shall prepare
and file with such Principal Trading Market an additional shares listing application covering all of the Shares and Warrant Shares and shall use its commercially reasonable efforts to take all steps necessary to cause all of the Shares and Warrant
Shares to be approved for listing on the Principal Trading Market as promptly as possible thereafter. 
 4.11 Form D; Blue
Sky. The Company agrees to timely file a Form D with respect to the Securities as required under Regulation D and to provide a copy thereof, promptly upon the written request of any Purchaser. The Company, on or before the Closing Date, shall
take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for or to qualify the Securities for sale to the Purchasers under applicable securities or “Blue Sky” laws of the states of the United
States (or to obtain an exemption from such qualification) and shall provide evidence of such actions promptly upon the written request of any Purchaser. 
 4.12 Delivery of Shares and Warrants After Closing. The Company shall deliver, or cause to be delivered, the respective Shares and Warrants purchased by each Purchaser to such Purchaser within
three (3) Trading Days of the Closing Date. 
 4.13 Additional Registration Statements. Until the date immediately
following the sixty (60) day anniversary of the Effective Date and at any time thereafter while any Registration Statement is not effective or the prospectus contained therein is not available for use, the Company shall not file a registration
statement under the Securities Act relating to securities that are not the Registrable Securities (as defined in the Registration Rights Agreement). 
 4.14 Additional Issuance of Securities. The Company agrees that for the period commencing on the date hereof and ending on the date immediately following the sixty (60) day anniversary of the
Effective Date (the “Restricted Period”), neither the Company nor any of its Subsidiaries shall directly or indirectly issue, offer, sell, grant any option or right to purchase, or otherwise dispose of (or announce any issuance,
offer, sale, grant of any option or right to purchase or other disposition of) any equity security or any equity-linked or related security (including, without limitation, any “equity security” (as that term is defined under Rule 405
promulgated under the Securities Act), any Convertible Securities (as defined below), any debt, any preferred stock or any purchase rights (any such issuance, offer, sale, grant, disposition or announcement (whether occurring during the Restricted
Period or at any time thereafter) is referred to as a “Subsequent Placement”). Notwithstanding the foregoing, this Section 4.14 shall not apply in respect of the issuance of (A) shares of Common Stock or standard options
to purchase Common Stock (including the issuance of Common Stock upon the exercise of such options) to directors, officers or employees of the Company in their capacity as such pursuant to an Approved Share Plan (as defined below), provided that the
exercise price of any such options is not lowered, none of such options are amended to increase the number of shares issuable thereunder and none of the terms or conditions of any such options are otherwise materially changed in any manner that
adversely affects any of the Purchasers; (B) shares of Common Stock issued upon the conversion or exercise of Convertible Securities (other than standard options to purchase Common Stock issued pursuant to an Approved Share Plan that are
covered 

  
 29 

 
by clause (A) above) issued prior to the date hereof, provided that the conversion or exercise price of any such Convertible Securities is not lowered, none of such Convertible Securities
are amended to increase the number of shares issuable thereunder and none of the terms or conditions of any such Convertible Securities are otherwise materially changed in any manner that adversely affects any of the Purchasers; (C) the Common
Shares and (D) the Warrant Shares (each of the foregoing in clauses (A) through (D), collectively the “Excluded Securities”). “Approved Share Plan” means any employee benefit plan which has been approved
by the board of directors of the Company prior to or subsequent to the date hereof pursuant to which shares of Common Stock and standard options to purchase Common Stock may be issued to any employee, officer or director for services provided to the
Company in their capacity as such. “Convertible Securities” means any capital stock or other security of the Company or any of its Subsidiaries that is at any time and under any circumstances directly or indirectly convertible into,
exercisable or exchangeable for, or which otherwise entitles the holder thereof to acquire, any capital stock or other security of the Company (including, without limitation, Common Stock) or any of its Subsidiaries. 

4.15 Variable Rate Transaction. Until none of the Warrants are outstanding, the Company and each Subsidiary shall be prohibited
from effecting or entering into an agreement to effect any Subsequent Placement involving a Variable Rate Transaction. “Variable Rate Transaction” means a transaction in which the Company or any Subsidiary issues or sells any
Convertible Securities either (A) at a conversion, exercise or exchange rate or other price that is based upon and/or varies with the trading prices of, or quotations for, the shares of Common Stock at any time after the initial issuance of
such Convertible Securities, or (B) with a conversion, exercise or exchange price that is subject to being reset at some future date after the initial issuance of such Convertible Securities or upon the occurrence of specified or contingent
events directly or indirectly related to the business of the Company or the market for the Common Stock, other than pursuant to a customary “weighted average” or “full ratchet” anti-dilution provision. Each Purchaser shall be
entitled to obtain injunctive relief against the Company and its Subsidiaries to preclude any such issuance, which remedy shall be in addition to any right to collect damages. 
 4.16 Participation Right. From the date hereof through the twelve (12) month anniversary of the Closing Date, neither the Company nor any of its Subsidiaries shall, directly or indirectly,
effect any Subsequent Placement unless the Company shall have first complied with this Section 4.16. The Company acknowledges and agrees that the right set forth in this Section 4.16 is a right granted by the Company, separately, to each
Purchaser. 
 (a) At least five (5) Trading Days prior to any proposed or intended Subsequent Placement, the Company shall
deliver to each Purchaser a written notice of its proposal or intention to effect a Subsequent Placement (each such notice, a “Pre-Notice”), which Pre-Notice shall not contain any information (including, without limitation,
material, non-public information) other than: (i) a statement that the Company proposes or intends to effect a Subsequent Placement and (ii) a statement informing such Purchaser that it is entitled to receive an Offer Notice (as defined
below) with respect to such Subsequent Placement upon its written request. Upon the written request of a Purchaser within three (3) Trading Days after the Company’s delivery to such Purchaser of such Pre-Notice, and only upon a written
request by such Purchaser, the Company shall promptly, but no later than one (1) Trading Day after such 

  
 30 

 
request, deliver to such Purchaser an irrevocable written notice (the “Offer Notice”) of any proposed or intended issuance or sale or exchange (the “Offer”) of
the securities being offered (the “Offered Securities”) in a Subsequent Placement, which Offer Notice shall (w) identify and describe the Offered Securities, (x) describe the price and other terms upon which they are to be
issued, sold or exchanged, and the number or amount of the Offered Securities to be issued, sold or exchanged, (y) identify the Persons (if known) to which or with which the Offered Securities are to be offered, issued, sold or exchanged and
(z) offer to issue and sell to or exchange with such Purchaser in accordance with the terms of the Offer 100% of the Offered Securities, provided that the number of Offered Securities which such Purchaser shall have the right to subscribe for
under this Section 4.16 shall be (a) based on such Purchaser’s pro rata portion of the aggregate number of Common Shares purchased hereunder by all Purchasers (the “Basic Amount”), and (b) with respect to each
Purchaser that elects to purchase its Basic Amount, any additional portion of the Offered Securities attributable to the Basic Amounts of other Purchasers as such Purchaser shall indicate it will purchase or acquire should the other Purchasers
subscribe for less than their Basic Amounts (the “Undersubscription Amount”). 
 (b) To accept an Offer, in
whole or in part, such Purchaser must deliver a written notice to the Company prior to the end of the fifth (5th) Business Day after such Purchaser’s receipt of the Offer Notice (the “Offer Period”), setting forth the
portion of such Purchaser’s Basic Amount that such Purchaser elects to purchase and, if such Purchaser shall elect to purchase all of its Basic Amount, the Undersubscription Amount, if any, that such Purchaser elects to purchase (in either
case, the “Notice of Acceptance”). If the Basic Amounts subscribed for by all Purchasers are less than the total of all of the Basic Amounts, then such Purchaser who has set forth an Undersubscription Amount in its Notice of
Acceptance shall be entitled to purchase, in addition to the Basic Amounts subscribed for, the Undersubscription Amount it has subscribed for; provided, however, if the Undersubscription Amounts subscribed for exceed the difference between the total
of all the Basic Amounts and the Basic Amounts subscribed for (the “Available Undersubscription Amount”), such Purchaser who has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of the
Available Undersubscription Amount as the Basic Amount of such Purchaser bears to the total Basic Amounts of all Purchasers that have subscribed for Undersubscription Amounts, subject to rounding by the Company to the extent it deems reasonably
necessary. Notwithstanding the foregoing, if the Company desires to modify or amend the terms and conditions of the Offer prior to the expiration of the Offer Period, the Company may deliver to each Purchaser a new Offer Notice and the Offer Period
shall expire on the fifth (5th) Business Day after such Purchaser’s receipt of such new Offer Notice. 
 (c) The
Company shall have five (5) Business Days from the expiration of the Offer Period above (i) to offer, issue, sell or exchange all or any part of such Offered Securities as to which a Notice of Acceptance has not been given by a Purchaser
(the “Refused Securities”) pursuant to a definitive agreement(s) (the “Subsequent Placement Agreement”), but only to the offerees described in the Offer Notice (if so described therein) and only upon terms and
conditions (including, without limitation, unit prices and interest rates) that are not more favorable to the acquiring Person or Persons or less favorable to the Company than those set forth in the Offer Notice and (ii) to publicly announce
(a) the execution of such Subsequent Placement Agreement, and (b) either (x) the consummation of the transactions contemplated by such Subsequent Placement Agreement or (y) the termination of such Subsequent Placement

  
 31 

 
Agreement, which shall be filed with the Commission on a Current Report on Form 8-K with such Subsequent Placement Agreement and any documents contemplated therein filed as exhibits thereto.

 (d) In the event the Company shall propose to sell less than all the Refused Securities (any such sale to be in the manner
and on the terms specified in Section 4.16(c) above), then such Purchaser may, at its sole option and in its sole discretion, reduce the number or amount of the Offered Securities specified in its Notice of Acceptance to an amount that shall be
not less than the number or amount of the Offered Securities that such Purchaser elected to purchase pursuant to Section 4.16(b) above multiplied by a fraction, (i) the numerator of which shall be the number or amount of Offered Securities
the Company actually proposes to issue, sell or exchange (including Offered Securities to be issued or sold to Purchasers pursuant to this Section 4.16 prior to such reduction) and (ii) the denominator of which shall be the original amount
of the Offered Securities. In the event that any Purchaser so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company may not issue, sell or exchange more than the reduced number or amount of
the Offered Securities unless and until such securities have again been offered to the Purchasers in accordance with Section 4.16(a) above. 
 (e) Upon the closing of the issuance, sale or exchange of all or less than all of the Refused Securities, such Purchaser shall acquire from the Company, and the Company shall issue to such Purchaser, the
number or amount of Offered Securities specified in its Notice of Acceptance. The purchase by such Purchaser of any Offered Securities is subject in all cases to the preparation, execution and delivery by the Company and such Purchaser of a separate
purchase agreement relating to such Offered Securities reasonably satisfactory in form and substance to such Purchaser and its counsel. 
 (f) Any Offered Securities not acquired by a Purchaser or other Persons in accordance with this Section 4.16 may not be issued, sold or exchanged until they are again offered to such Purchaser under
the procedures specified in this Agreement. 
 (g) The Company and each Purchaser agree that if any Purchaser elects to
participate in the Offer, neither the Subsequent Placement Agreement with respect to such Offer nor any other transaction documents related thereto (collectively, the “Subsequent Placement Documents”) shall include any term or
provision whereby such Purchaser shall be required to agree to any restrictions on trading as to any securities of the Company or be required to consent to any amendment to or termination of, or grant any waiver, release or the like under or in
connection with, any agreement previously entered into with the Company or any instrument received from the Company. 
 (h)
Notwithstanding anything to the contrary in this Section 4.16 and unless otherwise agreed to by such Purchaser, the Company shall either confirm in writing to such Purchaser that the transaction with respect to the Subsequent Placement has been
abandoned or shall publicly disclose its intention to issue the Offered Securities, in either case in such a manner such that such Purchaser will not be in possession of any material, non-public information, by the tenth (10th) Business Day
following delivery of the Offer Notice. If by such tenth (10th) Business Day, no public disclosure regarding a transaction with respect to the Offered Securities has been made, and no notice regarding the abandonment of such transaction

  
 32 

 
has been received by such Purchaser, such transaction shall be deemed to have been abandoned and such Purchaser shall not be in possession of any material, non-public information with respect to
the Company or any of its Subsidiaries. Should the Company decide to pursue such transaction with respect to the Offered Securities, the Company shall provide such Purchaser with another Offer Notice in accordance with, and subject to, the terms of
this Section 4.16 and such Purchaser will again have the right of participation set forth in this Section 4.16. The Company shall not be permitted to deliver more than one Offer Notice to such Purchaser in any sixty (60) day period,
except as expressly contemplated by the last sentence of Section 4.16(b). 
 (i) The restrictions contained in this
Section 4.16 shall not apply in connection with the issuance of any Excluded Securities. The Company shall not circumvent the provisions of this Section 4.16 by providing terms or conditions to one Purchaser that are not provided to all.

amendment, by the Company and Purchasers holding at least 75% of the Shares then outstanding or, in the case of a waiver, by the party against whom enforcement of any such waiver provision is sought. No waiver of any default with respect to any

the same consideration is also offered to all Purchasers who then hold Securities. 
 6.5 Construction. 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. 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. This Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any
party by virtue of the authorship of any provisions of this Agreement or any of the Transaction Documents. 
 6.6 Successors
and Assigns. The provisions of this Agreement shall inure to the benefit of and be binding upon the parties and their successors and permitted assigns. This Agreement, or any rights or obligations hereunder, may not be assigned by the Company
without the prior written consent of each Purchaser. Any Purchaser may assign its rights hereunder in whole or in part to any Person to whom such Purchaser assigns or transfers any Securities in compliance with the Transaction Documents and
applicable law, provided such transferee shall agree in writing to be bound, with respect to the transferred Securities, by the terms and conditions of this Agreement that apply to the “Purchasers”. 

6.7 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors
and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except each Purchaser Party is an intended third party beneficiary of Section 4.9. 

  
 36 

 6.8 Governing Law. All questions concerning the construction, validity, enforcement
and interpretation of this Agreement shall be 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 Proceedings
concerning the interpretation, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto or its respective Affiliates, employees or agents) shall be
commenced exclusively in the New York Courts. Each party hereto hereby irrevocably submits to the exclusive jurisdiction of the New York Courts for the adjudication of any dispute hereunder or in connection herewith or with any transaction
contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any Proceeding, any claim that it is not personally subject to the
jurisdiction of any such New York Court, or that such Proceeding has been commenced in an improper or inconvenient forum. Each party hereto hereby irrevocably waives personal service of process and consents to process being served in any such
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 manner permitted by law. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. 

6.9 Survival. Subject to applicable statute of limitations, the representations, warranties, agreements and covenants contained
herein shall survive the Closing and the delivery of the Securities. 
 6.10 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 the
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 signature page were an original thereof. 
 6.11 Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement
shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this
Agreement. 
 6.12 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without
limiting any similar provisions of) the Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods
therein provided, then such Purchaser may rescind or withdraw, in its sole discretion from time 

  
 37 

 
to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights; provided, however, that
in the case of a rescission of an exercise of a Warrant, the applicable Purchaser shall be required to return any shares of Common Stock subject to any such rescinded exercise notice concurrently with the return to such Purchaser of the aggregate
exercise price paid to the Company for such shares and the restoration of such Purchaser’s right to acquire such shares pursuant to such Purchaser’s Warrant. 
 6.13 Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and
substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company and the Transfer Agent of such loss, theft or
destruction and the execution by the holder thereof of a customary lost certificate affidavit of that fact and an agreement to indemnify and hold harmless the Company and the Transfer Agent for any losses in connection therewith or, if required by
the Transfer Agent, a bond in such form and amount as is required by the Transfer Agent. The applicants for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such
replacement Securities. If a replacement certificate or instrument evidencing any Securities is requested due to a mutilation thereof, the Company may require delivery of such mutilated certificate or instrument as a condition precedent to any
issuance of a replacement. 
 6.14 Remedies. In addition to being entitled to exercise all rights provided herein or
granted by law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss
incurred by reason of any breach of obligations described in the foregoing sentence and hereby agree to waive in any action for specific performance of any such obligation (other than in connection with any action for a temporary restraining order)
the defense that a remedy at law would be adequate. 
 6.15 Payment Set Aside. To the extent that the Company makes a
payment or payments to any Purchaser pursuant to any Transaction Document or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other person under any law (including, without
limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full
force and effect as if such payment had not been made or such enforcement or setoff had not occurred. 
 6.16 Adjustments in
Share Numbers and Prices. In the event of any stock split, subdivision, dividend or distribution payable in shares of Common Stock (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly
shares of Common Stock), combination or other similar recapitalization or event occurring after the date hereof and prior to the Closing, each reference in any Transaction Document to a number of shares or a price per share shall be deemed to be
amended to appropriately account for such event. 

  
 38 

 6.17 Independent Nature of Purchasers’ Obligations and Rights. The obligations
of each Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under any
Transaction Document. The decision of each Purchaser to purchase Securities pursuant to the Transaction Documents has been made by such Purchaser independently of any other Purchaser and independently of any information, materials, statements or
opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or any Subsidiary which may have been made or given by any other Purchaser or by
any agent or employee of any other Purchaser, and no Purchaser and none of its agents or employees shall have any liability to any other Purchaser (or any other Person) relating to or arising from any such information, materials, statements or
opinions. Nothing contained herein or in any other Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other
kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Purchaser acknowledges that no other
Purchaser has acted as agent for such Purchaser in connection with making its investment hereunder and that no Purchaser will be acting as agent of such Purchaser in connection with monitoring its investment in the Securities or enforcing its rights
under the Transaction Documents. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be
necessary for any other Purchaser to be joined as an additional party in any Proceeding for such purpose. It is expressly understood and agreed that each provision contained in this Agreement is between the Company and a Purchaser, solely, and not
between the Company and the Purchasers collectively and not between and among the Purchasers. 
 6.18 Termination. This
Agreement may be terminated and the sale and purchase of the Shares and the Warrants abandoned at any time prior to the Closing by either the Company or any Purchaser (with respect to itself only) upon written notice to the other, if the Closing has
not been consummated on or prior to 5:00 P.M., New York City time, on the Outside Date; provided, however, that the right to terminate this Agreement under this Section 6.18 shall not be available to any Person whose failure to
comply with its obligations under this Agreement has been the cause of or resulted in the failure of the Closing to occur on or before such time. The Company shall give prompt notice of any such termination to each other Purchaser. Nothing in this
Section 6.18 shall be deemed to release any party from any liability for any breach by such party of the terms and provisions of this Agreement or the other Transaction Documents or to impair the right of any party to compel specific
performance by any other party of its obligations under this Agreement or the other Transaction Documents. In the event of a termination pursuant to this Section 6.18, the Company shall promptly notify all non-terminating Purchasers.

2. Registration. 
 (a) On or prior to the Filing Deadline, the Company shall prepare and file with the Commission a Registration Statement covering the resale of all of the Registrable Securities not already covered by an
existing and effective Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415 or, if Rule 415 is not available for offers and sales of the Registrable Securities, by such other means of distribution of
Registrable Securities as the Company may reasonably determine (the “Initial Registration Statement”). The Initial Registration Statement shall be on Form S-3 (except if the Company is then ineligible to register for resale the
Registrable Securities on Form S-3, in which case such registration shall be on such other form available to the Company to register for resale the Registrable Securities as a secondary offering) subject to the provisions of Section 2(e)
and shall contain (except if otherwise required pursuant to written comments received from the Commission upon a review of such Registration Statement) the “Plan of Distribution” section attached hereto as Annex A (which may
be modified to respond to comments, if any, provided by the Commission). Notwithstanding the registration obligations set forth in this Section 2, in the event the Commission informs the Company that all of the Registrable Securities
cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering on a single registration statement, the Company agrees to promptly (i) inform each of the Holders thereof and use its commercially reasonable
efforts to file amendments to the Initial Registration Statement as required by the Commission and/or (ii) withdraw the Initial Registration Statement and file a new registration statement (a “New Registration Statement”), in
either case covering the maximum number of Registrable Securities permitted to be registered by the Commission, on Form S-3 or such other form available to the Company to register for resale the Registrable Securities as a secondary offering;
provided, however, that prior to filing such amendment or New Registration Statement, the Company shall be obligated to use its commercially reasonable efforts to advocate with the Commission for the registration of all of the Registrable Securities
in accordance with the SEC Guidance, including without limitation, Securities Act Rules Compliance and Disclosure Interpretation 612.09. Notwithstanding any other provision of this 

  
 4 

 
Agreement, if any SEC Guidance sets forth a limitation of the number of Registrable Securities or other shares of Common Stock, if any, permitted to be registered on a particular Registration
Statement as a secondary offering (and notwithstanding that the Company used diligent efforts to advocate with the Commission for the registration of all or a greater number of Registrable Securities), the number of Registrable Securities or other
shares of Common Stock to be registered on such Registration Statement will be reduced as follows: first, the Company shall reduce or eliminate the shares of Common Stock that are not Registrable Securities hereunder; and second, the Company shall
reduce the Registrable Securities to be included by all Holders on a pro rata basis based on the total number of unregistered Registarble Securities held by such Holders (with each Holder deciding, in its sole discretion, the manner in which its
Registrable Securities subject to reduction shall be reduced), subject to a determination by the Commission that certain Holders must be reduced before other Holders based on the number of Registrable Securities held by such Holders. In the event
the Company amends the Initial Registration Statement or files a New Registration Statement, as the case may be, under clauses (i) or (ii) above, the Company will use its commercially reasonable efforts to file with the Commission, as
promptly as allowed by Commission or SEC Guidance provided to the Company or to registrants of securities in general, one or more registration statements on Form S-3 or such other form available to the Company to register for resale those
Registrable Securities that were not registered for resale on the Initial Registration Statement, as amended, or the New Registration Statement (the “Remainder Registration Statements”). No Holder shall be named as an
“underwriter” in any Registration Statement without such Holder’s prior written consent. 
 (b) The Company shall
use its commercially reasonable efforts to cause each Registration Statement to be declared effective by the Commission as soon as practicable and, with respect to the Initial Registration Statement or the New Registration Statement, as applicable,
no later than the Effectiveness Deadline (including filing with the Commission a request for acceleration of effectiveness in accordance with Rule 461 promulgated under the Securities Act), and shall use its commercially reasonable efforts to keep
each Registration Statement continuously effective under the Securities Act until the earlier of (i) such time as all of the Registrable Securities covered by such Registration Statement have been publicly sold by the Holders or (ii) the
date that all Registrable Securities covered by such Registration Statement may be sold by non-affiliates without volume or manner-of-sale restrictions under Rule 144, without the requirement for the Company to be in compliance with the current
public information requirements under Rule 144(c)(1) (or Rule 144(i)(2), if applicable) (assuming for purposes of the foregoing determination, “cashless exercise” of the Warrants) as determined by counsel to the Company pursuant to a
written opinion letter to such effect, addressed and delivered to the Company’s transfer agent and reasonably acceptable to the effected Holders (the “Effectiveness Period”). The Company shall request effectiveness of a
Registration Statement as of 5:00 P.M. New York City time on a Trading Day. The Company shall promptly notify the Holders via facsimile or electronic mail of a “.pdf” format data file of the effectiveness of a Registration Statement prior
to 9:00 A.M. New York City time on the Trading Day immediately following the Effective Date. The Company shall, by 9:30 A.M. New York City time on the first Trading Day after the Effective Date, file a final Prospectus with the Commission, as
required by Rule 424(b). 
 (c) If: (i) the Initial Registration Statement is not filed with the Commission on or prior to
the Filing Deadline, (ii) the Initial Registration Statement or the New Registration 

  
 5 

 Statement, as applicable, is not declared effective by the Commission (or otherwise does not become
effective) for any reason on or prior to the Effectiveness Deadline, (iii) after its Effective Date, (A) such Registration Statement ceases for any reason (including without limitation by reason of a stop order, or the Company’s
failure to update the Registration Statement), to remain continuously effective as to all Registrable Securities included in such Registration Statement or (B) the Holders are not permitted to utilize the Prospectus therein to resell such
Registrable Securities (in each case of (A) and (B), other than during an Allowable Suspension Period), or (iv) after the date that is six months following the Closing Date, and only in the event a Registration Statement is not effective
or available to sell all Registrable Securities, the Company fails to file with the Commission any required reports under Section 13 or 15(d) of the Exchange Act such that it is not in compliance with Rule 144(c)(1) (or Rule
144(i)(2), if applicable) as a result of which the Holders who are not affiliates are unable to sell Registrable Securities without restriction under Rule 144 (or any successor thereto) (any such failure or breach in clauses (i) through
(iv) above being referred to as an “Event,” and the date on which such Event occurs being referred to as an “Event Date”), then in addition to any other rights the Holders may have hereunder or under applicable
law, on each such Event Date and on each monthly anniversary of each such Event Date (if the applicable Event shall not have been cured by such date) until the applicable Event is cured, the Company shall pay to each Holder an amount in cash, as
partial liquidated damages and not as a penalty (“Liquidated Damages”), equal to two percent (2.0%) of the aggregate purchase price paid by such Holder pursuant to the Purchase Agreement for any unregistered Registrable
Securities held by such Holder on the Event Date. The parties agree that (1) notwithstanding anything to the contrary herein or in the Purchase Agreement, no Liquidated Damages shall be payable (i) if as of the relevant Event Date, the
Registrable Securities may be sold by non-affiliates without volume or manner of sale restrictions under Rule 144 and the Company is in compliance with the current public information requirements under Rule 144(c)(1) (or Rule 144(i)(2), if
applicable), as determined by counsel to the Company pursuant to a written opinion letter to such effect, addressed and delivered to the Company’s transfer agent and reasonably acceptable to the effected Holders, and (ii) with respect to
any period after the expiration of the Effectiveness Period (it being understood that this sentence shall not relieve the Company of any Liquidated Damages accruing prior to the expiration of the Effectiveness Period) and in no event shall, the
aggregate amount of Liquidated Damages payable to a Holder exceed, in the aggregate, ten percent (10%) of the aggregate purchase price paid by such Holder pursuant to the Purchase Agreement and (2) in no event shall the Company be liable
in any thirty (30) day period for Liquidated Damages under this Agreement in excess of two percent (2.0%) of the aggregate purchase price paid by the Holders pursuant to the Purchase Agreement. If the Company fails to pay any Liquidated
Damages pursuant to this Section 2(c) in full within five (5) Business Days after the date payable, the Company will pay interest thereon at a rate of one and one-half percent (1.5%) per month (or such lesser maximum amount
that is permitted to be paid by applicable law) to the Holder, accruing daily from the date such Liquidated Damages are due until such amounts, plus all such interest thereon, are paid in full. The Liquidated Damages pursuant to the terms hereof
shall apply on a daily pro-rata basis for any portion of a month prior to the cure of an Event, except in the case of the first Event Date. The Company shall not be liable for Liquidated Damages under this Agreement as to any Registrable Securities
which are not permitted by the Commission to be included in a Registration Statement due solely to SEC Guidance from the time that it is determined that such Registrable Securities are not permitted to be registered until 

  
 6 

 such time as the provisions of this Agreement as to the Remainder Registration Statements required to be
filed hereunder are triggered, in which case the provisions of this Section 2(c) shall once again apply, if applicable. In such case, the Liquidated Damages shall be calculated to only apply to the percentage of Registrable Securities
which are permitted in accordance with SEC Guidance to be included in such Registration Statement. With respect to any Purchaser that fails to timely provide the Company with information requested by the Company and necessary to complete the
Registration Statement in accordance with the requirements of the Securities Act, the Effectiveness Deadline for a Registration Statement shall be extended without default or Liquidated Damages hereunder in the event that the Company’s failure
to obtain the effectiveness of the Registration Statement on a timely basis results from the failure of such Purchaser to timely provide the Company with such information (for purposes of clarification, the Effectiveness Deadline would be extended
only with respect to Registrable Securities held by such Purchaser and not with respect to Registrable Securities held by other Purchasers that have not failed to timely provide the Company with such information). 

(d) Each Holder agrees to furnish to the Company a completed Selling Stockholder Questionnaire not more than five (5) Trading Days
following the date of this Agreement. At least ten (10) Trading Days prior to the first anticipated filing date of a Registration Statement for any registration under this Agreement, the Company will notify each Holder of the information the
Company requires from that Holder other than the information contained in the Selling Stockholder Questionnaire, if any, which shall be completed and delivered to the Company promptly upon request and, in any event, within three (3) Trading
Days prior to the applicable anticipated filing date. Each Holder further agrees that it shall not be entitled to be named as a selling securityholder in the Registration Statement or use the Prospectus for offers and resales of Registrable
Securities at any time, unless such Holder has returned to the Company a completed and signed Selling Stockholder Questionnaire and a response to any requests for further information as described in the previous sentence. If a Holder of Registrable
Securities returns a Selling Stockholder Questionnaire or a request for further information, in either case, after its respective deadline, the Company shall use its commercially reasonable efforts to take such actions as are required to name such
Holder as a selling security holder in the Registration Statement or any pre-effective or post-effective amendment thereto and to include (to the extent not theretofore included) in the Registration Statement the Registrable Securities identified in
such late Selling Stockholder Questionnaire or request for further information. Each Holder acknowledges and agrees that the information in the Selling Stockholder Questionnaire or request for further information as described in this
Section 2(d) will be used by the Company in the preparation of the Registration Statement and hereby consents to the inclusion of such information in the Registration Statement. 

(e) In the event that Form S-3 is not available for the registration of the resale of Registrable Securities hereunder, the Company shall
(i) register the resale of the Registrable Securities on another appropriate form and (ii) undertake to register the Registrable Securities on Form S-3 promptly after such form is available, provided that the Company shall maintain the
effectiveness of the Registration Statement then in effect until such time as a Registration Statement on Form S-3 covering the Registrable Securities has been declared effective by the Commission.

 3. Registration Procedures 
 In connection with the Company’s registration obligations hereunder: 
 (a)
The Company shall, not less than five (5) Trading Days prior to the filing of each Registration Statement and not less than one (1) Trading Day prior to the filing of any related Prospectus or any amendment or supplement thereto (except
for Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K and any similar or successor reports), (i) furnish to the Holder copies of such Registration Statement, Prospectus or amendment or supplement
thereto, as proposed to be filed, which documents will be subject to the review of such Holder (it being acknowledged and agreed that if a Holder does not object to or comment on the aforementioned documents within such five (5) Trading Day or
one (1) Trading Day period, as the case may be, then the Holder shall be deemed to have consented to and approved the use of such documents) and (ii) use commercially reasonable efforts to cause its officers and directors, counsel and
independent registered public accountants to respond to such inquiries as shall be necessary, in the reasonable opinion of respective counsel to each Holder, to conduct a reasonable investigation within the meaning of the Securities Act. The Company
shall not file any Registration Statement or amendment or supplement thereto in a form to which a Holder reasonably objects in good faith, provided that, the Company is notified of such objection in writing within the five (5) Trading Day or
one (1) Trading Day period described above, as applicable. 
 (b) (i) The Company shall prepare and file with the
Commission such amendments (including post effective amendments) and supplements, to each Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement continuously effective as to the
applicable Registrable Securities for its Effectiveness Period; (ii) the Company shall cause the related Prospectus to be amended or supplemented by any required Prospectus supplement (subject to the terms of this Agreement), and, as so
supplemented or amended, to be filed pursuant to Rule 424; (iii) the Company shall respond as promptly as reasonably practicable to any comments received from the Commission with respect to each Registration Statement or any amendment thereto
and, as promptly as reasonably possible, provide the Holders true and complete copies of all correspondence from and to the Commission relating to such Registration Statement that pertains to the Holders as “Selling Stockholders” but not
any comments that would result in the disclosure to the Holders of material and non-public information concerning the Company; and (iv) the Company shall comply with the provisions of the Securities Act and the Exchange Act with respect to the
disposition of all Registrable Securities covered by a Registration Statement until such time as all of such Registrable Securities shall have been disposed of (subject to the terms of this Agreement) in accordance with the intended methods of
disposition by the Holders thereof as set forth in such Registration Statement as so amended or in such Prospectus as so supplemented; provided, however, that each Purchaser shall be responsible for the delivery of the Prospectus to the Persons to
whom such Purchaser sells any of the Registrable Securities (including in accordance with Rule 172 under the Securities Act), and each Purchaser agrees to dispose of Registrable Securities in compliance with the “Plan of Distribution”
described in the Registration Statement and otherwise in compliance with applicable federal and state securities laws. In the case of amendments and supplements to a Registration Statement which are required to be filed pursuant to this Agreement
(including pursuant to this Section 3(b)) by reason of the Company filing a report on Form 10-K, Form 10-Q or Form 8-K or any analogous report under the Exchange Act, the Company shall have incorporated such report by reference into such

  
 8 

 Registration Statement, if applicable, or shall file such amendments or supplements with the Commission on
the same day on which the Exchange Act report which created the requirement for the Company to amend or supplement such Registration Statement was filed. 
 (c) The Company shall notify the Holders (which notice shall, pursuant to clauses (iii) through (vi) hereof, be accompanied by an instruction to suspend, subject to the limitations on
suspensions set forth in Section 6(d), the use of the Prospectus until the requisite changes have been made) as promptly as reasonably practicable (and, in the case of (i)(A) below, not less than one (1) Trading Day prior to such
filing) and (if requested by any such Person) confirm such notice in writing no later than one (1) Trading Day following the day: (i)(A) when a Prospectus or any Prospectus supplement or post effective amendment to a Registration Statement is
proposed to be filed; (B) when the Commission notifies the Company whether there will be a “review” of such Registration Statement and whenever the Commission comments in writing on any Registration Statement (in which case the
Company shall provide to each of the Holders true and complete copies of all comments that pertain to the Holders as a “Selling Stockholder” or to the “Plan of Distribution” and all written responses thereto, but
not information that the Company believes would constitute material and non-public information); and (C) with respect to each Registration Statement or any post effective amendment, when the same has become effective; (ii) of any request
by the Commission or any other Federal or state governmental authority for amendments or supplements to a Registration Statement or Prospectus or for additional information that pertains to the Holders as “Selling Stockholders” or the
“Plan of Distribution”; (iii) of the issuance by the Commission or any other federal or state governmental authority of any stop order suspending the effectiveness of a Registration Statement covering any or all of the Registrable
Securities or the initiation of any Proceedings for that purpose; (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities
for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; (v) of the occurrence of any event or passage of time that makes the financial statements included in a Registration Statement ineligible for
inclusion therein or any statement made in such Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to such Registration
Statement, Prospectus or other documents so that, in the case of such Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein (in the case of any Prospectus, form of prospectus or supplement thereto, in light of the circumstances under which they were made), not misleading and (vi) of the occurrence or existence of
any pending corporate development with respect to the Company that the Company believes may be material and that, in the determination of the Company, makes it not in the best interest of the Company to allow continued availability of a Registration
Statement or Prospectus, provided that the Company shall not disclose the content of any of any material, non-public information to the Holders. 
 (d) The Company shall use commercially reasonable efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of a Registration Statement, or
(ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, as soon as practicable. 

  
 9 

 (e) The Company shall, if requested by a Holder, furnish to such Holder, without charge, at
least one conformed copy of each Registration Statement and each amendment thereto and all exhibits to the extent requested by such Person (including those previously furnished or incorporated by reference) promptly after the filing of such
documents with the Commission; provided, that the Company shall have no obligation to provide any document pursuant to this clause that is available on the Commission’s EDGAR system. 

(f) The Company shall, prior to any resale of Registrable Securities by a Holder, use its commercially reasonable efforts to register or
qualify or cooperate with the selling Holders in connection with the registration or qualification (or exemption from the registration or qualification) of such Registrable Securities for the resale by the Holder under the securities or Blue Sky
laws of such jurisdictions within the United States as any Holder reasonably requests in writing, to keep each registration or qualification (or exemption therefrom) effective during the Effectiveness Period and to do any and all other acts or
things reasonably necessary to enable the disposition in such jurisdictions of the Registrable Securities covered by each Registration Statement; provided, that the Company shall not be required to qualify generally to do business in any
jurisdiction where it is not then so qualified, subject the Company to any material tax in any such jurisdiction where it is not then so subject or file a general consent to service of process in any such jurisdiction. 

(g) The Company shall cooperate with the Holders to facilitate the timely preparation and delivery of certificates representing
Registrable Securities to be delivered to a transferee pursuant to the Registration Statement, which certificates shall be free, to the extent permitted by the Purchase Agreement and under law, of all restrictive legends, and to enable such
Registrable Securities to be in such denominations and registered in such names as any such Holders may reasonably request. Certificates for Registrable Securities free from all restrictive legends may be transmitted by the Company’s transfer
agent to a Holder by crediting the account of such Holder’s prime broker with DTC as directed by such Holder. 
 (h) The
Company shall, following the occurrence of any event contemplated by Section 3(c), as promptly as reasonably practicable (taking into account the Company’s good faith assessment of any adverse consequences to the Company and its
stockholders of the premature disclosure of such event), prepare and file a supplement or amendment, including a post effective amendment, to the affected Registration Statements or a supplement to the related Prospectus or any document incorporated
or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, no Registration Statement nor any Prospectus will 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 (in the case of any Prospectus, form of prospectus or supplement thereto, in light of the circumstances under which they were made), not misleading. 

(i) The Company may require each selling Holder to furnish to the Company a certified statement as to (i) the number of shares of
Common Stock beneficially owned by such Holder and any Affiliate thereof, (ii) any Financial Industry Regulatory Authority (“FINRA”) affiliations, (iii) any natural persons who have the power to vote or dispose of the
Common Stock and (iv) any other information as may be requested by the Commission, FINRA or any state securities commission. During any periods that the Company is unable to meet its 

  
 10 

 obligations hereunder with respect to the registration of Registrable Securities because any Holder fails to
furnish such information within three (3) Trading Days of the Company’s request, any Liquidated Damages that are accruing at such time as to such Holder only shall be tolled and any Event that may otherwise occur solely because of such
delay shall be suspended as to such Holder only, until such information is delivered to the Company. 
 (j) The Company shall
cooperate with any registered broker through which a Holder proposes to resell its Registrable Securities in effecting a filing with FINRA pursuant to FINRA Rule 5110 as requested by any such Holder and the Company shall pay the filing fee required
for the first such filing within two (2) Business Days of the request therefor. 
 (k) The Company agrees to promptly
deliver to each Holder, without charge, as many copies of each Prospectus or Prospectuses (including each form of prospectus) and each amendment or supplement thereto as such Persons may reasonably request. The Company hereby consents to the use of
such Prospectus and each amendment or supplement thereto by each of the selling Holders in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto. 

(l) Provided the Company is eligible to use Form S-3 as of the date of this Agreement or becomes eligible to use Form S-3 during the term
of this Agreement, the Company shall use its commercially reasonable efforts to maintain eligibility for use of Form S-3 (or any successor form thereto) for the registration of the resale of Registrable Securities. 

(m) If requested by a Holder, the Company shall (i) promptly incorporate in a Prospectus supplement or post-effective amendment to
the Registration Statement such information as the Company reasonably agrees should be included therein and (ii) make all required filings of such Prospectus supplement or such post-effective amendment as soon as reasonably practicable after
the Company has received notification of the matters to be incorporated in such Prospectus supplement or post-effective amendment. 
 (n) The Company shall otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the Commission under the Securities Act and the Exchange Act, including Rule 172,
notify the Holders promptly if the Company no longer satisfies the conditions of Rule 172 and take such other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities hereunder; and make available to its
security holders, as soon as reasonably practicable, but not later than the Availability Date (as defined below), an earnings statement covering a period of at least twelve (12) months, beginning after the effective date of each Registration
Statement, which earning statement shall satisfy the provisions of Section 11(a) of the Securities Act, including Rule 158 promulgated thereunder (for the purpose of this Section 3, “Availability Date” means the
45th day following the end of the fourth fiscal quarter that includes the effective date of such Registration Statement, except that, if such fourth fiscal quarter is the last quarter of the Company’s fiscal year, “Availability Date”
means the 90th day after the end of such fourth fiscal quarter). 
 4. Registration Expenses. All fees and expenses
incident to the Company’s performance of or compliance with its obligations under this Agreement (excluding any underwriting discounts and selling commissions and all legal fees and expenses of legal counsel 

  
 11 

 for any Holder) shall be borne by the Company whether or not any Registrable Securities are sold pursuant to
a Registration Statement. The fees and expenses referred to in the foregoing sentence shall include, without limitation, (i) all registration and filing fees (including, without limitation, fees and expenses (A) with respect to filings
required to be made with any Trading Market on which the Common Stock is then listed for trading, (B) with respect to compliance with applicable state securities or Blue Sky laws (including, without limitation, fees and disbursements of counsel
for the Company in connection with Blue Sky qualifications or exemptions of the Registrable Securities and determination of the eligibility of the Registrable Securities for investment under the laws of such jurisdictions as requested by the
Holders) and (C) if not previously paid by the Company in connection with an issuer filing, with respect to any filing that may be required to be made by any broker through which a Holder intends to make sales of Registrable Securities with
FINRA pursuant to FINRA Rule 5110, so long as the broker is receiving no more than a customary brokerage commission in connection with such sale, (ii) printing expenses (including, without limitation, expenses of printing certificates for
Registrable Securities and of printing Prospectuses if the printing of Prospectuses is reasonably requested by the Holders of a majority of the Registrable Securities included in the Registration Statement), (iii) messenger, telephone and
delivery expenses, (iv) fees and disbursements of counsel for the Company, (v) Securities Act liability insurance, if the Company so desires such insurance, and (vi) fees and expenses of all other Persons retained by the Company in
connection with the consummation of the transactions contemplated by this Agreement. In addition, the Company shall be responsible for all of its internal expenses incurred in connection with the consummation of the transactions contemplated by this
Agreement (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit and the fees and expenses incurred in connection with the listing of the
Registrable Securities on any securities exchange as required hereunder. In no event shall the Company be responsible for any underwriting, broker or similar fees or commissions of any Holder or, except to the extent provided for in the Transaction
Documents, any legal fees or other costs of the Holders. 
 5. Indemnification. 

(a) Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify, defend and
hold harmless each Holder, the officers, directors, agents, partners, members, managers, stockholders, Affiliates and employees of each of them, each Person who controls any such Holder (within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act) and the officers, directors, partners, members, managers, stockholders, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any
and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable costs of preparation and investigation and reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that
arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus or any form of prospectus or in any amendment or supplement thereto or in any preliminary
prospectus, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement
thereto, in light of the circumstances under which they were made) not misleading, or (ii) any violation or alleged violation by the Company of the Securities Act, Exchange Act or any state securities law 

  
 12 

 or any rule or regulation thereunder, in connection with the performance of its obligations under this
Agreement, except to the extent, but only to the extent, that (A) such untrue statements, alleged untrue statements, omissions or alleged omissions are based solely upon information regarding such Holder furnished in writing to the Company by
such Holder expressly for use therein, or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and approved in writing by such Holder expressly
for use in the Registration Statement, such Prospectus or such form of Prospectus or in any amendment or supplement thereto (it being understood that each Holder has approved Annex A hereto for this purpose) or (B) in the case of an
occurrence of an event of the type specified in Section 3(c)(iii)-(vi), related to the use by a Holder of an outdated or defective Prospectus after the Company has notified such Holder in writing that the Prospectus is outdated or
defective and prior to the receipt by such Holder of the Advice contemplated and defined in Section 6(d) below, but only if and to the extent that following the receipt of the Advice the misstatement or omission giving rise to such Loss
would have been corrected or (C) to the extent that any such Losses arise out of the Purchaser’s (or any other indemnified Person’s) failure to send or give a copy of the Prospectus or supplement (as then amended or supplemented), if
required, pursuant to Rule 172 under the Securities Act (or any successor rule) to the Persons asserting an untrue statement or alleged untrue statement or alleged untrue statement or omission or alleged omission at or prior to the written
confirmation of the sale of Registrable Securities to such Person if such statement or omission was corrected in such Prospectus or supplement. The Company shall notify the Holders promptly of the institution, threat or assertion of any Proceeding
arising from or in connection with the transactions contemplated by this Agreement of which the Company is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an Indemnified Party (as
defined in Section 5(c)) and shall survive the transfer of the Registrable Securities by the Holders. 
 (b)
Indemnification by Holders. Each Holder shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers, agents and employees, each Person who controls the Company (within the meaning of
Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the fullest extent permitted by applicable law, from and against all
Losses, as incurred, arising out of or are based solely upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus, or any form of prospectus, or in any amendment or supplement thereto or
in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus, or any form of prospectus
or supplement thereto, in light of the circumstances under which they were made) not misleading (i) to the extent that such untrue statements or omissions are based solely upon information regarding such Holder furnished in writing to the
Company by such Holder expressly for use therein or (ii) to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and approved in writing by such
Holder expressly for use in a Registration Statement (it being understood that the Holder has approved Annex A hereto for this purpose), such Prospectus or such form of Prospectus or in any amendment or supplement thereto or (iii) in the
case of an occurrence of an event of the type specified in Section 3(c)(iii)-(vi), to the extent related to the use by such Holder of an outdated or defective Prospectus after the Company has notified such Holder in writing that the
Prospectus is outdated or defective and prior to the receipt by such

Holder of the Advice contemplated in Section 6(d), but only if and to the extent that following the receipt of the Advice the misstatement or omission giving rise to such Loss would
have been corrected. In no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the net proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such
indemnification obligation. 
 (c) Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted
against any Person entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the
Indemnifying Party shall have the right to assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all reasonable fees and expenses incurred in connection with defense
thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally
determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have materially and adversely prejudiced the Indemnifying Party. 

An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such fees and expenses; (2) the Indemnifying Party shall have failed promptly to assume
the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party
and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that a conflict of interest exists if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified
Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and such counsel shall be at the
expense of the Indemnifying Party); provided, that the Indemnifying Party shall not be liable for the fees and expenses of more than one separate firm of attorneys at any time for all Indemnified Parties. The Indemnifying Party shall not be liable
for any settlement of any such Proceeding effected without its written consent, which consent shall not be unreasonably withheld, delayed or conditioned. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect
any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such
Proceeding. 
 Subject to the terms of this Agreement, all fees and expenses of the Indemnified Party (including reasonable fees and expenses to
the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section 5) shall be paid to the Indemnified Party, as incurred, within twenty (20) Trading Days of
written notice thereof to the Indemnifying Party; provided, that the Indemnified Party shall promptly reimburse the Indemnifying Party for that portion of such fees and expenses applicable to such actions for which such Indemnified Party is finally
judicially determined to not be entitled to indemnification hereunder). The failure to deliver written notice to the Indemnifying Party 

  
 14 

 
within a reasonable time of the commencement of any such action shall not relieve such Indemnifying Party of any liability to the Indemnified Party under this Section 5, except to the
extent that the Indemnifying Party is materially and adversely prejudiced in its ability to defend such action. 
 (d)
Contribution. If a claim for indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party or insufficient to hold an Indemnified Party harmless for any Losses, then each Indemnifying Party, in lieu of
indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified
Party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference
to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such
Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any
Losses shall be deemed to include, subject to the limitations set forth in this Agreement, any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any Proceeding to the extent such party would
have been indemnified for such fees or expenses if the indemnification provided for in this Section 5 was available to such party in accordance with its terms. 
 The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by pro rata allocation or by any other method of allocation that
does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 5(d), (A) no Holder shall be required to contribute, in the aggregate, any
amount in excess of the amount by which the net proceeds actually received by such Holder from the sale of the Registrable Securities subject to the Proceeding exceeds the amount of any damages that such Holder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged omission and (B) no contribution will be made under circumstances where the maker of such contribution would not have been required to indemnify the Indemnified Party
under the fault standards set forth in this Section 5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation. 
 The indemnity and contribution agreements contained in this Section 5 are in
addition to any liability that the Indemnifying Parties may have to the Indemnified Parties and are not in diminution or limitation of the indemnification provisions under the Purchase Agreement. 

6. Miscellaneous. 
 (a) Remedies. In the event of a breach by the Company or by a Holder of any of their obligations under this Agreement, each Holder or the Company, as the case may be, in addition to being entitled
to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this 

  
 15 

 
Agreement. The Company and each Holder agree that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it of any of the provisions of this
Agreement and hereby further agrees that, in the event of any action for specific performance in respect of such breach, it shall waive the defense that a remedy at law would be adequate. 

(b) No Piggyback on Registrations; Prohibition on Filing Other Registration Statements. Except and to the extent specified in the
Disclosure Schedules to the Purchase Agreement, neither the Company nor any of its security holders (other than the Holders in such capacity pursuant hereto) may include securities of the Company in a Registration Statement other than the
Registrable Securities and the Company shall not prior to the Effective Date enter into any agreement providing any such right to any of its security holders. The Company shall not file with the Commission a registration statement relating to an
offering for its own account under the Securities Act of any of its equity securities other than a registration statement on Form S-8 or, in connection with an acquisition, on Form S-4 until the earlier of (i) the date that is thirty
(30) days after the Initial Registration Statement or New Registration Statement, as the case may be, is declared effective or (ii) the date that all Registrable Securities are eligible for resale by non-affiliates without volume or manner
of sale restrictions under Rule 144 and without the requirement for the company to be in compliance with the current public information requirements under Rule 144(c)(1) (or Rule 144(i)(2), if applicable). For the avoidance of doubt, the Company
shall not be prohibited from preparing and filing with the Commission a registration statement relating to an offering of Common Stock by existing stockholders of the Company under the Securities Act pursuant to the terms of registration rights held
by such stockholder or from filing amendments to registration statements filed prior to the date of this Agreement. 
 (c)
Compliance. Each Holder covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it (unless an exemption therefrom is available) in connection with sales of Registrable
Securities pursuant to the Registration Statement and shall sell the Registrable Securities only in accordance with a method of distribution described in the Registration Statement 

(d) Discontinued Disposition. By its acquisition of Registrable Securities, each Holder agrees that, upon receipt of a notice from
the Company of the occurrence of any event of the kind described in Section 3(c)(iii)-(vi), such Holder will forthwith discontinue disposition of such Registrable Securities under a Registration Statement until it is advised in writing
(the “Advice”) by the Company that the use of the applicable Prospectus (as it may have been supplemented or amended) may be resumed. The Company will use its commercially reasonable efforts to ensure that the use of the Prospectus
may be resumed as promptly as is practicable. The Company shall be entitled to exercise its right under this Section 6(d) to suspend the availability of a Registration Statement and Prospectus, subject to the payment of partial
Liquidated Damages otherwise required pursuant to Section 2(c), for a period not to exceed twenty (20) consecutive calendar days or forty (40) calendar days (which need not be consecutive days) in any twelve (12) month
period (each suspension period complying with this provision, an “Allowable Suspension Period”). 

  
 16 

 (e) No Inconsistent Agreements. Neither the Company nor any of its Subsidiaries has
entered, as of the date hereof, nor shall the Company or any of its Subsidiaries, on or after the date hereof, enter into any agreement with respect to its securities, that would have the effect of impairing the rights granted to the Holders in this
Agreement or otherwise conflicts with the provisions hereof. 
 (f) Amendments and Waivers. The provisions of this
Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, or waived unless the same shall be in writing and signed by the Company and Holders holding no less than two-thirds of the then outstanding
Registrable Securities, provided that any party may give a waiver as to itself. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders and
that does not directly or indirectly affect the rights of other Holders may be given by Holders of all of the Registrable Securities to which such waiver or consent relates; provided, however, that the provisions of this sentence may not be amended,
modified, or supplemented except in accordance with the provisions of the immediately preceding sentence. Notwithstanding the foregoing, if any such amendment, modification or waiver would adversely affect in any material respect any Holder or group
of Holders who have comparable rights under this Agreement disproportionately to the other Holders having such comparable rights, such amendment, modification, or waiver shall also require the written consent of the Holder(s) so adversely affected.

 (g) Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder
shall be delivered as set forth in the Purchase Agreement. 
 (h) Successors and Assigns. This Agreement shall inure to
the benefit of and be binding upon the successors and permitted assigns of each of the parties and shall inure to the benefit of each Holder. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties
hereto or their respective successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. The Company may not assign its rights (except by merger or in
connection with another entity acquiring all or substantially all of the Company’s assets) or obligations hereunder without the prior written consent of all the Holders of the then outstanding Registrable Securities. Each Holder may assign its
respective rights hereunder in the manner and to the Persons as permitted under the Purchase Agreement; provided in each case that (i) the Holder agrees in writing with the transferee or assignee to assign such rights and related obligations
under this Agreement, and for the transferee or assignee to assume such obligations, and a copy of such agreement is furnished to the Company within a reasonable time after such assignment, (ii) the Company is, within a reasonable time after
such transfer or assignment, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being transferred or assigned, (iii) at or before the time
the Company received the written notice contemplated by clause (ii) of this sentence, the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained herein and (iv) the transferee is an
“accredited investor,” as that term is defined in Rule 501 of Regulation D. 

  
 17 

 (i) Execution and Counterparts. This Agreement may be executed in two or more
counterparts, each of which when so executed shall be deemed to be an original and, all of which taken together shall constitute 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 were the original thereof. 

(j) Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be
determined in accordance with the provisions of the Purchase Agreement. 
 (k) Cumulative Remedies. The remedies provided
herein are cumulative and not exclusive of any other remedies provided by law. 
 (l) 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 good faith 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. 
 (m) Headings. The headings in this
Agreement are for convenience only and shall not limit or otherwise affect the meaning hereof. 
 (n) Independent Nature of
Purchasers’ Obligations and Rights. The obligations of each Purchaser under this Agreement are several and not joint with the obligations of any other Purchaser hereunder, and no Purchaser shall be responsible in any way for the performance
of the obligations of any other Purchaser hereunder. The decision of each Purchaser to purchase the Securities pursuant to the Transaction Documents has been made independently of any other Purchaser. Nothing contained herein or in any other
agreement or document delivered at any closing, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a
presumption that the Purchasers are in any way acting in concert with respect to such obligations or the transactions contemplated by this Agreement. Each Purchaser acknowledges that no other Purchaser has acted as agent for such Purchaser in
connection with making its investment hereunder and that no Purchaser will be acting as agent of such Purchaser in connection with monitoring its investment in the Securities or enforcing its rights under the Transaction Documents. Each Purchaser
shall be entitled to protect and enforce its rights, including, without limitation, the rights arising out of this Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional 

  
 18 

 
party in any Proceeding for such purpose. The Company acknowledges that each of the Purchasers has been provided with the same Registration Rights Agreement for the purpose of closing a
transaction with multiple Purchasers and not because it was required or requested to do so by any Purchaser.

 ANNEX A 

PLAN OF DISTRIBUTION 
 We
are registering the shares of Common Stock issued to the selling stockholders and issuable upon exercise of the warrants issued to the selling stockholders to permit the resale of these shares of Common Stock by the holders of the shares of Common
Stock and warrants from time to time after the date of this prospectus. We will not receive any of the proceeds from the sale by the selling stockholders of the shares of Common Stock. We will bear all fees and expenses incident to our obligation to
register the shares of Common Stock. 
 The selling stockholders may sell all or a portion of the shares of Common Stock beneficially owned by
them and offered hereby from time to time directly or through one or more underwriters, broker-dealers or agents. If the shares of Common Stock are sold through underwriters or broker-dealers, the selling stockholders will be responsible for
underwriting discounts or commissions or agent’s commissions. The shares of Common Stock may be sold on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale, in the
over-the-counter market or in transactions otherwise than on these exchanges or systems or in the over-the-counter market and in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices
determined at the time of sale, or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions. The selling stockholders may use any one or more of the following methods when selling shares:

  

	 	•	 	 ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers; 

 

	 	•	 	 block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to
facilitate the transaction; 

  

	 	•	 	 purchases by a broker-dealer as principal and resale by the broker-dealer for its account; 

 

	 	•	 	 an exchange distribution in accordance with the rules of the applicable exchange; 

 

	 	•	 	 privately negotiated transactions; 

  

	 	•	 	 settlement of short sales entered into after the effective date of the registration statement of which this prospectus is a part;

  

	 	•	 	 broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;

  

	 	•	 	 through the writing or settlement of options or other hedging transactions, whether such options are listed on an options exchange or otherwise;

	 	•	 	 a combination of any such methods of sale; and 

  

	 	•	 	 any other method permitted pursuant to applicable law. 

 The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act, as permitted by that rule, or
Section 4(1) under the Securities Act, if available, rather than under this prospectus, provided that they meet the criteria and conform to the requirements of those provisions. 
 Broker dealers engaged by the selling stockholders may arrange for other broker dealers to participate in sales. If the selling stockholders effect such transactions by selling shares of Common Stock to
or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from purchasers of the shares of
Common Stock for whom they may act as agent or to whom they may sell as principal. Such commissions will be in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction will not be in
excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with FINRA IM-2440. 
 In connection with sales of the shares of Common Stock or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn
engage in short sales of the shares of Common Stock in the course of hedging in positions they assume. The selling stockholders may also sell shares of Common Stock short and if such short sale shall take place after the date that this Registration
Statement is declared effective by the Commission, the selling stockholders may deliver shares of Common Stock covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The selling
stockholders may also loan or pledge shares of Common Stock to broker-dealers that in turn may sell such shares, to the extent permitted by applicable law. The selling stockholders may also enter into option or other transactions with broker-dealers
or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other
financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). Notwithstanding the foregoing, the selling stockholders have been advised that they may not use shares registered on this
registration statement to cover short sales of our Common Stock made prior to the date the registration statement, of which this prospectus forms a part, has been declared effective by the SEC. 

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the warrants or shares of Common Stock owned by
them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of Common Stock from time to time pursuant to this prospectus or any amendment to this prospectus under Rule
424(b)(3) or other applicable provision of the Securities Act of 1933, as amended, amending, if necessary, the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this
prospectus. The selling stockholders also may transfer and donate the shares of Common Stock in other 

  
 23 

 
circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus. 

The selling stockholders and any broker-dealer or agents participating in the distribution of the shares of Common Stock may be deemed to be
“underwriters” within the meaning of Section 2(11) of the Securities Act in connection with such sales. In such event, any commissions paid, or any discounts or concessions allowed to, any such broker-dealer or agent and any
profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Selling Stockholders who are “underwriters” within the meaning of Section 2(11) of the
Securities Act will be subject to the applicable prospectus delivery requirements of the Securities Act including Rule 172 thereunder and may be subject to certain statutory liabilities of, including but not limited to, Sections 11, 12 and 17 of the
Securities Act and Rule 10b-5 under the Securities Exchange Act of 1934, as amended, or the Exchange Act. 
 Each selling stockholder has
informed the Company that it is not a registered broker-dealer and does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the Common Stock. Upon the Company being notified in writing by a
selling stockholder that any material arrangement has been entered into with a broker-dealer for the sale of Common Stock through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer, a
supplement to this prospectus will be filed, if required, pursuant to Rule 424(b) under the Securities Act, disclosing (i) the name of each such selling stockholder and of the participating broker-dealer(s), (ii) the number of shares
involved, (iii) the price at which such the shares of Common Stock were sold, (iv) the commissions paid or discounts or concessions allowed to such broker-dealer(s), where applicable, (v) that such broker-dealer(s) did not conduct any
investigation to verify the information set out or incorporated by reference in this prospectus, and (vi) other facts material to the transaction. In no event shall any broker-dealer receive fees, commissions and markups, which, in the
aggregate, would exceed eight percent (8.0%). 
 Under the securities laws of some states, the shares of Common Stock may be sold in such states
only through registered or licensed brokers or dealers. In addition, in some states the shares of Common Stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or
qualification is available and is complied with. 
 There can be no assurance that any selling stockholder will sell any or all of the shares of
Common Stock registered pursuant to the shelf registration statement, of which this prospectus forms a part. 
 Each selling stockholder and any
other person participating in such distribution will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including, without limitation, to the extent applicable, Regulation M of the Exchange Act, which
may limit the timing of purchases and sales of any of the shares of Common Stock by the selling stockholder and any other participating person. To the extent applicable, Regulation M may also restrict the ability of any person engaged in the
distribution of the shares of Common Stock to engage in market-making activities with respect to the shares of Common Stock. All of the foregoing may affect the marketability of the shares of Common Stock and the ability of any person or entity to
engage in market-making activities with respect to the shares of Common Stock. 

  
 24 

 We will pay all expenses of the registration of the shares of Common Stock pursuant to the registration
rights agreement, including, without limitation, Securities and Exchange Commission filing fees and expenses of compliance with state securities or “blue sky” laws; provided, however, that each selling stockholder will pay all underwriting
discounts and selling commissions, if any and any related legal expenses incurred by it. We will indemnify the selling stockholders against certain liabilities, including some liabilities under the Securities Act, in accordance with the registration
rights agreement, or the selling stockholders will be entitled to contribution. We may be indemnified by the selling stockholders against civil liabilities, including liabilities under the Securities Act, that may arise from any written information
furnished to us by the selling stockholders specifically for use in this prospectus, in accordance with the related registration rights agreements, or we may be entitled to contribution.

ascribed thereto in the Agreement.
