incorporation, bylaws or other organizational or charter documents. The Company is duly qualified to do business and is in good standing as a foreign corporation or other entity in each jurisdiction in which the nature of the business conducted

volume of the shares of Common Stock of the Company or (B) changes in general economic conditions or changes affecting the industry in which the Company operates generally (as opposed to Company-specific changes) so long as such changes do not

duly executed and delivered by the Company and constitutes, and the certificates representing the Common Stock and Warrants, when executed and delivered in accordance with the terms hereof, will constitute, a valid and binding obligation of the
Company enforceable against the Company in accordance with its terms, except as may be limited by (i) applicable bankruptcy, insolvency, reorganization or other laws of general application relating to or affecting the enforcement of
creditors’ rights generally; (ii) the effect of rules of law governing the availability of specific performance, injunctive relief and other equitable remedies; and (iii) insofar as indemnification and contribution provisions may be
limited by applicable law.

the Company of this Agreement or the issuance, sale or delivery of the Securities other than the Required Approvals. Subject to the Required Approvals, the execution and delivery by the Company of this Agreement and the certificates representing the
Common Stock and the Warrants, and the performance by the Company of its obligations hereunder and thereunder, do not and will not (i) conflict with or violate any provision of the Company’s certificate of incorporation, bylaws or other
organizational or charter documents, (ii) conflict with, or constitute a default under (or an event that, with notice or lapse of time or both, would become a default under), or give to others any rights of termination, amendment, acceleration
or cancellation under (with or without notice, lapse of time or both), any agreement, credit facility, debt or other instrument evidencing a debt of the Company or other understanding to which the Company is a party, or by which any of its
properties or assets is bound, except to the extent that such conflict or default or termination, amendment, acceleration or cancellation right would not reasonably be expected to have a Material Adverse Effect, or (iii) result in a violation
of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Company is subject, or by which any of its properties or assets is bound, except to the extent that such
violation would not reasonably be expected to have a Material Adverse Effect.

agreements entered into by the Company relating hereto. Except as disclosed in the SEC Reports, there is no pending or, to the best knowledge of the Company, threatened action, suit, proceeding or investigation before any court, governmental
agency or body, or arbitrator having jurisdiction over the Company, or any of its Affiliates which litigation if adversely determined would reasonably be expected to have a Material Adverse Effect.

the SEC Reports: (i) to the knowledge of the Company, no third party has infringed, misappropriated, diluted or otherwise violated in any material respect any Intellectual Property rights of the Company or any of its subsidiaries, and no claims
for any of the foregoing have been brought against any third party by the Company or any of its subsidiaries; (ii) the Intellectual Property owned by the Company or its subsidiaries and, to the knowledge of the Company, the Intellectual
Property licensed to the Company or its subsidiaries have not been adjudged invalid or unenforceable, in whole or in part, and there is no pending or, to the knowledge of the Company, threatened action, suit, proceeding, investigation or claim
challenging the validity, enforceability, scope, issuance/registration, use or ownership of any such Intellectual Property, and the Company is unaware of any facts which would form a reasonable basis for any such claim; (iii) there is no

property and proprietary rights. 
 (h) Property. The Company does not own any real property. The Company and its subsidiaries have
good and marketable title to all properties and assets described in the SEC Reports as owned by it, in each case free and clear of all Liens, except such as (i) are described in the SEC Reports or (ii) do not materially affect the value of
such property and do not interfere with the use made and proposed to be made of such property by the Company and its subsidiaries. Any real property and buildings held under lease by the Company and its subsidiaries are held by them under valid,

appropriate governmental or regulatory agencies or authorities (collectively, “Permits”) that are necessary to enable them to own, lease and operate their respective properties and to carry on their respective businesses as

liability or development has occurred or exists with respect to the Company or its subsidiaries or their respective business, properties, operations or financial condition, that would be required to be disclosed by the Company under applicable
securities laws at the time this representation is made or deemed made that has not been publicly disclosed at least one Trading Day prior to the date that this representation is made. 

(l) Transactions with Related Parties. Except as set forth in the SEC Reports, none of the officers or directors of the Company and,
to the knowledge of the Company, none of the employees of the Company is presently a party to any transaction with the Company or any subsidiary (other than for services as employees, officers and directors), including any contract, agreement or
other arrangement providing for the furnishing of services to or by, providing for rental of real or personal property to or from, or otherwise requiring payments to or from any officer, director or such employee or, to the knowledge of the Company,
any entity in which any officer, director, or any such employee has a substantial interest or is an officer, director, trustee or partner, in each case as would be required to be disclosed pursuant to the requirements of Item 404 of Regulation
S-K. 
 (m) Nature of Company’s Obligation. The Company further acknowledges that its obligations under the Transaction
Agreements, including, without limitation, its obligation to issue the Warrant Shares, are unconditional and absolute and not subject to any right of set off, counterclaim, delay or reduction, regardless of the effect of any such dilution or any
claim the Company may have against any Purchaser and regardless of the dilutive effect that such issuance may have on the ownership of the other stockholders of the Company. 

(n) No Defaults. Except as disclosed in the Company’s SEC Reports, the Company and its Subsidiaries are not, nor have they
received notice that they would be with the passage of time, giving of notice, or both, in breach or violation of any of the terms and provisions of, or in default under (a) their charters and bylaws, (b) any statute, rule, regulation or
order of any governmental agency or body or any court, domestic or foreign, having jurisdiction over them, or any of their material assets or properties, or (c) any material agreement or instrument to which they are a party or by which they are
bound or to which any of their assets or properties are subject, except, in the case of clauses (b) and (c) only, for such conflicts, breaches or violations as have not and are not reasonably be expected to result in, individually or in
the aggregate, a Material Adverse Effect. 
 (o) Insurance. The Company, on behalf of itself and its subsidiaries, carries, or is
covered by, insurance from insurers of recognized financial responsibility in such amounts and covering such risks as is customary for companies engaged in similar businesses in similar industries. All policies of insurance of the Company and its
subsidiaries are in full force and effect; each of the Company and its subsidiaries is in compliance with the terms of such policies in all material respects; and none of the Company or its subsidiaries has received notice from any insurer or agent
of such insurer that capital improvements or other expenditures are required or necessary to be made in order to continue such insurance; there are no claims by the Company or any of its subsidiaries under any such policy or instrument as to which
any insurance company is denying liability or defending under a reservation of rights clause; and none of the Company or its subsidiaries has any reason to believe that it will not be able 

  
 9 

 
to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that could
not reasonably be expected to have a Material Adverse Effect. 
 (p) Taxes. The Company has filed all federal, state, local and
foreign income and franchise tax returns required to be filed through the date hereof, subject to permitted extensions, and has paid all taxes due thereon, and no tax deficiency has been determined adversely to the Company, nor does the Company have
any knowledge of any tax deficiencies that could, in the aggregate, reasonably be expected to have a Material Adverse Effect. There is no pending dispute with any taxing authority relating to the Company’s payment of taxes in any material
amount except which the Company is contesting in good faith and the Company has no knowledge of any proposed liability for any tax to be imposed upon the properties or assets of the Company for which there is not an adequate reserve reflected in the
Company’s financial statements included or incorporated by reference in the SEC Reports. 
 (q) Trading Market. Except as
disclosed in the SEC Reports, the Company has not, in the twelve (12) months preceding the date hereof, received notice from the Nasdaq Stock Market to the effect that the Company is not in compliance with the listing or maintenance
requirements of the Nasdaq Stock Market. Except as described in the SEC Reports, the Company has no reason to believe that it will not in the foreseeable future continue to be in compliance or regain compliance in a timely manner, as the case may
be, with all such listing and maintenance requirements. The issuance and sale of the Securities hereunder does not contravene, in a manner which is expected to have a Material Adverse Effect, the rules and regulations of the Nasdaq Stock Market and
no stockholder approval is required for the Company to fulfill its obligations under the Transaction Agreements. The Common Stock has been registered pursuant to Section 12(b) of the Exchange Act and is currently listed on the Nasdaq Stock
Market. 
 (r) SEC Reports. The Company has filed all SEC Reports required to be filed by it under the Exchange Act for the two
years preceding the date hereof on a timely basis or has received a valid extension of such time of filing and has filed any such SEC Reports prior to the expiration of any such extension. As of their respective dates, the SEC Reports filed for the
two years preceding the date hereof have complied in all material respects with the requirements of the Exchange Act and the rules and regulations promulgated thereunder, and none of such SEC Reports, when filed, contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. 

(s) Sarbanes-Oxley Compliance. The Company is in compliance in all material respects with all provisions of the Sarbanes-Oxley Act of
2002, as amended, applicable to it, and the applicable rules and regulations promulgated thereunder by all government and regulatory authorities and agencies. The Company maintains a system of internal accounting controls sufficient to provide
reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with
generally accepted accounting principles in the United States and to maintain accountability for assets, (iii) access to assets is permitted only in accordance with management’s general or specific authorization and (iv) the recorded
accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect thereto. The Company has established and maintains and evaluates “disclosure controls and procedures” (as
such term is defined in Rule 13a-15 and Rule 15d-15 under the Exchange Act) and “internal control over financial reporting” (as such term is defined in Rule 13a-15 and Rule 15d-15 under the Exchange Act). The Company’s certifying
officers have evaluated the effectiveness of the Company’s disclosure controls and procedures and the Company presented in its most recent periodic report filed for a completed fiscal quarter in accordance with the Exchange Act, the conclusions
of the Company’s certifying officers about the effectiveness of such disclosure controls and procedures.

 (t) Certain Fees. No brokerage or finder’s fees or commissions are or will be
payable by the Company or any Subsidiary to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the transactions contemplated by the Transaction Agreements. The Purchasers
shall have no obligation with respect to any fees or with respect to any claims made by or on behalf of other Persons for fees of a type contemplated in this Section that may be due in connection with the transactions contemplated by the Transaction

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

3.2 Representations, Warranties and Acknowledgements of the Purchasers. Each Purchaser, severally and not jointly, represents and
warrants with respect to only itself, as of the Closing Date, that: 
 (a) Organization; Authority. Each Purchaser certifies
that it is resident in the jurisdiction set out on the applicable signature page of this Agreement. Such address was not created and is not used solely for the purpose of acquiring the Securities and each Purchaser was solicited to purchase in
such jurisdiction. The Purchaser is either a natural person or an entity, and in the case of an entity, (i) such Purchaser is an entity duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization
and has the requisite corporate, partnership or other power and authority to enter into this Agreement, to subscribe for and purchase the Securities as contemplated herein and to carry out its obligations hereunder, and (ii) the execution and
delivery of, and performance under, this Agreement and the other Transaction Agreements have been duly authorized by all necessary corporate, partnership or other action on the part of such Purchaser. The Purchaser is duly authorized to
execute, deliver and perform this Agreement, the other Transaction Agreements and all other necessary documentation. In the case of all Purchasers, whether or not a natural person, this Agreement has been duly authorized, executed and delivered by
such Purchaser and constitutes a legal, valid and binding obligation of each such Purchaser, enforceable against him, her or it in accordance with its terms, except as may be limited by (A) applicable bankruptcy, insolvency, reorganization or
other laws of general application relating to or affecting the enforcement of creditors’ rights generally, (B) the effect of rules of law governing the availability of specific performance and other equitable remedies, and (C) insofar
as indemnification and contribution provisions may be limited by applicable law. 
 (b) No Conflicts. The execution, delivery and
performance by the Purchaser of this Agreement and each of the Transaction Agreements to which it is a party, and the consummation by the Purchaser of the transactions contemplated by this Agreement and each such Transaction Agreement, do not and
will not (i) conflict with or violate any provision of the Purchaser’s certificate of incorporation, bylaws or other organizational or charter documents, or (ii) conflict with or result in a violation of any law, rule, regulation,
order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Purchaser is subject (including federal and state securities laws and regulations), or by which any property or asset of the Purchaser is
bound or affected. 
 (c) No 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 solicitation or general advertisement. 

  
 11 

 (d) Restricted Securities. Each Purchaser understands that the Common Stock, the
Warrants, and the Warrant Shares, will be characterized as “restricted securities” under U.S. federal securities laws inasmuch as, if issued, they will be acquired from the Company in a transaction not involving a public offering and that,
under U.S. federal securities laws and applicable regulations, the Common Stock, the Warrants, and the Warrant Shares may be resold without registration under the Securities Act only in certain limited circumstances. Such Purchaser acknowledges
that all certificates representing any of the shares of Common Stock, the Warrants, and the Warrant Shares will bear a restrictive legend in a form as set forth below and hereby consents to the transfer agent for the Company’s Common Stock
making a notation on its records to implement the restrictions on transfer described herein. Such Purchaser understands that except as provided in the Transaction Agreements: (i) the Securities have not been and are not being registered
under the Securities Act or any state securities laws, must be held indefinitely and may not be offered for sale, sold, assigned or transferred unless (A) subsequently registered thereunder, (B) such Purchaser shall have delivered to the
Company an opinion of counsel, in a generally acceptable form, to the effect that such Securities to be sold, assigned or transferred may be sold, assigned or transferred pursuant to an exemption from such registration, or (C) such Purchaser
provides the Company with reasonable assurance that such Securities can be sold, assigned or transferred pursuant to Rule 144 or Rule 144A promulgated under the Securities Act (or a successor rule thereto) (collectively, “Rule
144”); (ii) any sale of the Securities made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144 and further, if Rule 144 is not applicable, any resale of the Securities under circumstances in which the
seller (or the Person (through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the Securities Act) may require compliance with some other exemption under the Securities Act or the rules and regulations of the
Commission thereunder; (iii) neither the Company nor any other Person is under any obligation to register the Securities under the Securities Act or any state securities laws or to comply with the terms and conditions of any exemption
thereunder; and (iv) the Company shall bear the reasonable expenses of any legal opinions relating to (I) the sale of Securities made in reliance on Rule 144 by any Purchaser that is not an “affiliate” as defined in Rule 144 made
after the first anniversary of the Closing Date or (II) any private sale or other transfer of Securities. 
 (e) Certain Legends.

 (i) Such Purchaser understands that: 

(A) the Securities are “restricted securities” and that the certificates or other instruments representing the Common Stock and the
Warrant Shares shall bear any applicable legend as required under U.S. federal securities laws and by the “blue sky” laws of any state and a restrictive legend in substantially the following form (and a stop-transfer order may be placed
against transfer of such certificates): 
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND
EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION 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, ASSIGNED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT, OR APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN
AVAILABLE EXEMPTION THEREFROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH
EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY; 

  
 12 

 and (B) the Warrants shall bear a legend as set forth on Exhibit A. 

(ii) The Company may at any time place a stop transfer order on its transfer books against the shares of Common Stock issued pursuant to this
Agreement, including the Warrant Shares. Such stop order will be removed, and further transfer of such shares of Common Stock and Warrant Shares will be permitted, upon an effective registration of the respective shares of Common Stock and Warrant
Shares or the receipt by the Company of an opinion of counsel satisfactory to the Company that such further transfer may be effected pursuant to an applicable exemption from registration. 

(f) Reliance on Representations. Such Purchaser understands that the Securities are being offered and sold to it in reliance on
specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and such Purchaser’s compliance with, the representations,
warranties, agreements, acknowledgments and understandings of such Purchaser set forth herein and in the applicable schedules and exhibits in order to determine the availability of such exemptions and the eligibility of such Purchaser to acquire the
Securities. The Purchaser undertakes to immediately notify the Company of any change in any statement or other information relating to the Purchaser set forth in such applicable schedules and exhibits which takes place prior to the Closing time. No
Person has made any written or oral representations to the Purchaser that (i) any Person will resell or repurchase the shares of Common Stock, the Warrants or the Warrant Shares, (ii) that any Person will refund all or any part of the
Purchase Price, or (iii) as to the future price or value of the shares of Common Stock of the Company. 
 (g) Schedules. Each
Purchaser acknowledges that this Agreement and Schedule A attached hereto require the Purchaser to provide certain personal information to the Company. Such information is being collected by the Company for the purposes of completing the
transactions contemplated by this Agreement, which includes, without limitation, determining the Purchaser’s eligibility to purchase the Securities under the securities laws applicable in the United States and other applicable securities laws,
preparing and registering certificates representing the Securities and completing filings required by any stock exchange or securities regulatory authority. The Purchaser’s personal information may be disclosed by the Company to:
(a) stock exchanges or securities regulatory authorities, (b) any of the other parties involved in the Offering, including legal counsel and may be included in record books in connection with the Offering, and (c) pursuant to any
disclosure requirements existing under the U.S. federal or state securities laws. By executing this Agreement, the Purchaser is deemed to be consenting to the foregoing collection, use and disclosure of the Purchaser’s personal
information; provided, that in the event of a disclosure pursuant to clause (a) of the preceding sentence, the Company shall (to the extent it is legally permitted), use commercially reasonable efforts to give such Purchaser advance notice of
any required disclosure. The Purchaser also consents to the filing of copies or originals of any of the Purchaser’s documents as may be required to be filed with any stock exchange or securities regulatory authority in connection with the
transactions contemplated hereby.
 (h) No Public Sale or Distribution. Each Purchaser will be acquiring the Common Stock, the
Warrants and the Warrant Shares, in the ordinary course of business for his, her or its own account and not for the benefit of any other Person and not with a view towards, or for resale in connection with, the public sale or distribution thereof,
and the Purchaser covenants that it will not resell the Common Stock, the Warrants and the Warrant Shares except pursuant to sales registered under the Securities Act or under an exemption from such registration and in compliance with applicable
U.S. federal and state securities laws, and such Purchaser does not have a present arrangement to effect any distribution of the Common Stock, the Warrants and the Warrant Shares to or through any Person or entity. 

  
 13 

 (i) Investor Status. On the date such Purchaser was offered the Securities and on
the date hereof and such Purchaser is and will be either an “accredited investor” as defined in Rule 501(a) promulgated under Regulation D of the Securities Act or a “qualified institutional buyer” as defined in
Rule 144A(a) under the Securities Act. The Purchaser has properly completed, executed and delivered to the Company the applicable “accredited investor” certificate set forth in the Schedules hereto and the information contained
therein is true and correct. Such Purchaser is not required to be registered as a broker-dealer under Section 15 of the Exchange Act. 

(j) Experience of Purchaser. There are risks associated with the purchase of and investment in the Securities, and the Purchaser,
either alone or together with his, her or 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 entering into this Agreement and making his,
her or its Purchase Price and the merits and risks of the prospective investment in the Securities, and such Purchaser has so evaluated such merits and risks. Such Purchaser understands that he, she or it must bear the economic risk of an
investment in the Securities, if any, indefinitely and is able to bear such risk and to afford a complete loss of such investment. 
 (k)
Access to Information. Such Purchaser acknowledges that he, she or it has reviewed the SEC Reports and has been afforded (i) the opportunity to ask such questions as he, she or it has deemed necessary of, and to receive answers
from, representatives of the Company concerning the terms and conditions of this Agreement and the merits and risks of the prospective investment in the Securities, (ii) access to information about the Company and its Subsidiaries and their
respective financial condition, results of operations, business, properties, management and prospects sufficient to enable him, her or it to evaluate the terms and conditions of this Agreement and the merits and risks of the prospective investment
in the Securities 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 decision. The Purchaser is not purchasing
the Units based on knowledge of material information concerning the Company that has not been generally disclosed. Such Purchaser and its advisors, if any, in acquiring the Securities, have relied solely on their independent investigation of the
Company and have been afforded the opportunity to ask questions of the Company. Neither such inquiries nor any other due diligence investigations conducted by such Purchaser or its advisors, if any, or its representatives shall modify, amend or
affect such Purchaser’s right to rely on the Company’s representations and warranties contained herein. Such Purchaser understands that its investment in the Securities involves a high degree of risk. Such Purchaser has sought such
accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Securities. 

(l) No Governmental Review. Each Purchaser understands that no United States federal or state agency, or any other government or
governmental agency has reviewed or passed on or made, or will pass on or make, any recommendation or endorsement of the Securities or the fairness or suitability of the prospective investment in the Securities. 

(m) Aggregate Investment. Each Purchaser understands that his, her or its subscription for the Securities forms part of a larger
offering of Securities by the Company as described herein. Each Purchaser understands that there is no minimum aggregate subscription required to close the Offering.

(n) Securities and Other Transactions. Other than consummating the transactions contemplated hereunder, the Purchaser has not,
nor has any Person acting on behalf of or pursuant to any 

  
 14 

 
understanding with the Purchaser, directly or indirectly executed any purchases or sales, including Short Sales, of the securities of the Company during the period commencing as of the time that
the Purchaser first became aware of the proposed transactions contemplated hereunder and ending immediately prior to the execution hereof. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby
separate portfolio managers manage separate portions of the Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of the Purchaser’s
assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Units covered by this Agreement. Other than to other Persons party
to this Agreement and its Affiliates and their respective investment advisors, agents, counsel and other advisors, the Purchaser has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the
existence and terms of this transaction). Such Purchaser has no present intent to effect a “change of control” of the Company as such term is understood under the rules promulgated pursuant to Section 13(d) of the Exchange Act. 

(o) No Legal, Tax or Investment Advice. Each Purchaser understands that nothing in this Agreement or any other materials
presented by or on behalf of the Company to him, her or it in connection with this Agreement and the transactions contemplated herein, including the prospective investment in the Securities, constitutes legal, tax or investment advice. Each
Purchaser has consulted such legal, tax and investment advisors as he, she or it, in his, her or its sole discretion, has deemed necessary or appropriate in the circumstances. The Purchaser is not relying on the Company or its counsel in this
regard. 
 (p) Certain Fees. Each Purchaser represents on behalf of itself that it was not introduced to the Company by any
broker-dealer, investment banker, investment advisor or other intermediary, except as may be set forth on a separate schedule to this Agreement. The Purchaser’s participation in the transactions contemplated by this Agreement will not result in
the Company or any Subsidiary being obligated for the payment of any brokerage or finder’s fees or commissions to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the
transactions contemplated by this Agreement. 
 The Company acknowledges and agrees that the Purchaser does not make or has not made any
representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in this Section 3.2.

all times reserve and keep available out of its authorized but unissued shares of Common Stock, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue shares of Common Stock issued upon the exercise of the
Warrants issued as part of the Units purchased pursuant to this Agreement. 
 6.2 Securities Laws Disclosure; Publicity. The Company
shall, by 5:30 p.m. (New York City time) on the fourth Trading Day immediately following the date hereof, file a Current Report on Form 8-K disclosing the material terms of the transactions contemplated hereby and including the form of this
Agreement as an exhibit thereto. From and after the issuance of such Form 8-K, the Company shall have publicly disclosed all material, non-public information delivered to any Purchaser by the Company or any of its subsidiaries, or any of their
respective officers, directors, employees or agents in connection with the transactions contemplated by this Agreement. Except for information that may be provided to the Purchaser pursuant to the Registration Rights Agreement, the Company shall
not, and shall use commercially reasonable efforts to cause each of its officers, directors, employees and agents not to, provide Purchaser with any material nonpublic information regarding the Company from and after the filing of such Form 8-K
without the express written consent of such Purchaser. The Company 

  
 16 

 
understands and confirms that the Purchaser will rely on the representations and covenants set forth in this Section 6.2 in effecting transactions in securities of the Company. The Company
and the Purchasers shall consult with each other in issuing any press releases with respect to the transactions contemplated hereby, and neither the Company nor the Purchasers shall issue any such press release without the prior consent of the
Company, with respect to any press release of any of the Purchasers, or without the prior consent of the Majority in Interest, with respect to any press release of the Company, which consent shall not unreasonably be withheld or delayed, except if
such disclosure is required by law, in which case the disclosing party shall promptly provide the other party with prior notice of such public statement or communication. 

6.3 Use of Proceeds. The Company shall use the additional net proceeds from the sale of the Securities hereunder for general business
and working capital purposes. 
 6.4 Form D and Blue Sky; Listing of Common Stock; Reporting Status. The Company agrees to file a
Form D with respect to the Securities as required under Regulation D promulgated under the Securities Act and to promptly provide a copy thereof to any Purchaser who requests a copy after such filing. 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 Units for sale to the Purchasers at Closing pursuant to this Agreement under the applicable securities or “blue
sky” laws of the states of the United States (or to obtain an exemption from such qualification), and if requested by a Purchaser, shall provide evidence of any such action so taken. The Company shall make such filings and reports relating to
the offer and sale of the Units as required under applicable securities or “blue sky” laws of the states of the United States following or on the Closing Date. No Purchaser shall incur any costs or expenses relating to Form D or such
filings under applicable securities or “blue sky” laws. The Company hereby agrees to use commercially reasonable efforts to maintain the listing of the Common Stock on the Nasdaq Stock Market, and as soon as reasonably practicable, to list
all of the shares of Common Stock issuable pursuant to this Agreement. Until the earlier of (i) the date on which the Purchaser shall have sold all of the Warrant Shares and (ii) the date on which the Purchaser may sell all of the
Securities without restriction pursuant to Rule 144 and without the requirement to be in compliance with Rule 144(c)(1) (or any successor thereto) promulgated under the Securities Act (the “Reporting Period”), the Company shall
timely file all reports required to be filed with the Commission pursuant to the Exchange Act, and the Company shall not terminate its status as an issuer required to file reports under the Exchange Act even if the Exchange Act or the rules and
regulations thereunder would no longer require or otherwise permit such termination. 
 6.5 Certain Transactions and Confidentiality.
Each Purchaser covenants that neither it nor any Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or sales, including Short Sales, of any of the Company’s securities during the period commencing
with the execution of this Agreement and ending at such time that the transactions contemplated by this Agreement are first publicly announced pursuant to Section 6.2. Each Purchaser covenants that until such time as the
transactions contemplated by this Agreement are publicly disclosed by the Company pursuant to Section 6.2, such Purchaser will maintain the confidentiality of the existence and terms of this transaction. Notwithstanding the
foregoing and notwithstanding anything contained in this Agreement to the contrary, the Company expressly acknowledges and agrees that unless a Purchaser possesses material, non-public information with respect to the Company, has entered into a
confidentiality agreement with the Company, or otherwise is restricted in its trading activities with respect to the Company’s Common Stock, (i) no Purchaser makes any representation, warranty or covenant hereby that it will not engage in
effecting transactions in any securities of the Company after the time that the transactions contemplated by this Agreement are first publicly announced; (ii) no Purchaser shall be restricted or prohibited from effecting any transactions in any
securities of the Company in accordance with applicable securities laws from and after the time that the transactions contemplated by this Agreement are first publicly announced; and (iii) no Purchaser shall have any duty of confidentiality to
the Company or its Subsidiaries relating to this Agreement after the initial disclosure of the transactions contemplated by this Agreement. 

  
 17 

 6.6 Integration. The Company shall not 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 would be integrated with the offer or sale of the Securities to the Purchasers in a manner that would require the registration under the
Securities Act of the sale of the Securities to the Purchasers. 
 6.7 Transfer Restrictions. The Securities may only be disposed of
in compliance with state and federal securities laws. In connection with any transfer of Securities other than pursuant to an effective registration statement, to the Company or to an affiliate of a Purchaser or to an entity managed by a Purchaser
(provided, in such case the prospective transferee agrees in all such instances in writing to be subject to the terms hereof to the same extent as if he or she were an original Purchaser hereunder), the Company may require the transferor thereof to
provide to the Company an opinion of counsel, 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; provided that the Company shall bear the reasonable expense of any legal opinions relating to (I) the sale of Securities made in reliance on Rule 144 by any Purchaser that is not an “affiliate” as defined in Rule 144 made after
the first anniversary of the Closing Date or (II) any private sale or other transfer of Securities. As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement. Each Purchaser, severally and not
jointly with the other Purchasers, agrees with the Company that such Purchaser will sell any Securities pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an
exemption therefrom, and that if Securities are sold pursuant to a Registration Statement, they will be sold in compliance with the plan of distribution set forth therein. 

6.8 Right of Participation. 

(a) From the date hereof until the date that is the first anniversary of the Closing Date, upon any issuance by the Company of Common
Stock or Common Stock Equivalents for cash consideration (a “Subsequent Financing”), each Purchaser shall have the right to participate in up to an amount of the Subsequent Financing such that such Purchaser’s beneficial
ownership of the Company (ignoring for such purpose any beneficial ownership caps) on a fully diluted basis immediately following such Subsequent Financing would not be less than its beneficial ownership of the Company (ignoring for such purposes
any beneficial ownership caps) solely based on such Purchaser’s investment in this Offering (the “Participation Maximum”) on the same terms, conditions and price provided for in the Subsequent Financing. 

(b) At least five (5) Trading Days prior to the closing of the Subsequent Financing, the Company shall deliver to each Purchaser a
written notice of its intention to effect a Subsequent Financing (“Pre-Notice”), which Pre-Notice shall ask such Purchaser if it wants to review the details of such financing (such additional notice, a “Subsequent Financing
Notice”). Upon the request of a Purchaser, and only upon a request by such Purchaser, for a Subsequent Financing Notice, the Company shall promptly, but no later than two (2) Trading Days after such request, deliver a Subsequent
Financing Notice to such Purchaser. The Subsequent Financing Notice shall describe in reasonable detail the proposed terms of such Subsequent Financing, the amount of proceeds intended to be raised thereunder and the Person or Persons through
or with whom such Subsequent Financing is proposed to be effected and shall include a term sheet or similar document relating thereto as an attachment. 

(c) Any Purchaser desiring to participate in such Subsequent Financing must provide written notice to the Company by not later than 5:30
p.m. (New York City time) on the second 

  
 18 

 
(2nd) Trading Day after all of the Purchasers have received the Subsequent Financing Notice that such Purchaser is willing to participate in
the Subsequent Financing, the amount of such Purchaser’s participation, and representing and warranting that such Purchaser has such funds ready, willing, and available for investment on the terms set forth in the Subsequent Financing Notice.
If the Company receives no such notice from a Purchaser as of such second (2nd) Trading Day, such Purchaser shall be deemed to have notified the Company that it does not elect to participate.

 (d) If by 5:30 p.m. (New York City time) on the second (2nd) Trading Day
after all of the Purchasers have received the Subsequent Financing Notice, notifications by the Purchasers of their willingness to participate in the Subsequent Financing (or to cause their designees to participate) is, in the aggregate, less than
the total amount of the Subsequent Financing, then the Company may effect the remaining portion of such Subsequent Financing on the terms and with the Persons set forth in the Subsequent Financing Notice.

(e) The Company must provide the Purchasers with a second Subsequent Financing Notice, and the Purchasers will again have the right of
participation set forth above in this Section 6.8, if the Subsequent Financing subject to the initial Subsequent Financing Notice is not consummated for any reason on the terms set forth in such Subsequent Financing Notice within sixty
(60) Trading Days after the date of the initial Subsequent Financing Notice. 
 (f) Notwithstanding the foregoing, this
Section 6.8 shall not apply in respect of an Exempt Issuance or to a registered primary public offering. The right of first refusal set forth in this Section 6.8 is nonassignable, except that (i) such right is assignable by a
Purchaser to any Affiliate of the Purchaser, (ii) upon the death of any individual Purchaser, such right shall pass to the beneficiaries under the deceased Purchaser’s last will and testament or to the distributees of the deceased
Purchaser’s estate, and (iii) such right is assignable by a partnership or limited liability company to its partners or members, as applicable.

 ARTICLE VIII 

GENERAL 
 8.1
Termination. Solely in the event that the Closing has not been consummated on or before November 18, 2013, this Agreement may be terminated by any Purchaser, as to such Purchaser’s obligations hereunder only and without any effect
whatsoever on the obligations between the Company and the other Purchasers, by written notice to the other parties; provided, however, that (a) any Purchaser may elect to extend the foregoing date solely with respect to its purchase of
the Securities hereunder and (b) any such termination will not affect the right of any party to sue for any breach by the other party (or parties). 

8.2 Confidentiality. The Purchasers acknowledge that due to certain of the covenants contained herein or in the other Transaction
Agreements, from time to time the Purchasers may come into possession of confidential information of the Company, including material, non-public information relating to the Company. The Purchasers hereby agree that (i) they shall keep all such
information strictly confidential, applying, at a minimum, the same degree of care as it does to protect its own confidential information of a similar nature; (ii) shall only use such information in connection with the transactions contemplated
by this Agreement; and (iii) shall not disclose any of such information other than: (a) to the Purchaser’s employees, representatives, directors, attorneys, auditors, or Affiliates who are advised of the confidential nature of such
information (so long as any of the foregoing persons agree to be bound by the provisions of this Section), (b) to the extent such information presently is or hereafter becomes available on a non-confidential basis from any source of such
information that is in the public domain at the time of disclosure, (c) to the extent disclosure is required by law (including applicable securities law), regulation, subpoena or judicial order or any administrative body or commission to whose
jurisdiction the Purchasers are subject (provided that notice of such requirement or order shall be promptly furnished to the Company in advance of such disclosure), (d) to assignees or participants or prospective assignees or
participants who agree to be bound by the provisions of this Section, or (e) with the Company’s prior written consent. The Purchasers agree to be responsible for any breach of this agreement by any of the persons identified in
Section 8.2(iii). The Purchasers are aware that, under certain circumstances, the United States securities laws may prohibit a Person who has received material, non-public information from an issuer from purchasing or selling securities
of such issuer or from communicating such information to any other Person under circumstances in which it is reasonably foreseeable that such other Person is likely to purchase or sell such securities. 

8.3 Fees and Expenses. Except as expressly set forth in this Agreement to the contrary, each party shall pay the fees and expenses of
its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such party incident to the negotiation, preparation, execution, delivery and performance of this Agreement. Notwithstanding the foregoing, however, at
the Closing, the Company has agreed to pay to Hahn & Hessen, LLP, counsel to the lead investor, an amount not to exceed $25,000, in payment for its reasonable legal fees incurred in connection with the transactions contemplated by this
Agreement. 
 8.4 Amendments; Waivers. No provision of this Agreement may be amended or waived except in a written instrument
signed, (i) in the case of an amendment, by the Company and Purchasers representing a Majority in Interest, or (ii) in the case of a waiver, by the party against whom enforcement of any such waiver is sought; provided that, in the
case of waiver by or on behalf of all of the Purchasers, such written instrument shall be signed by Purchasers representing a Majority in Interest; and provided, further that that any amendment that would modify this Section 8.4 shall,
in each case, require the approval of each Purchaser to which such amendment shall apply. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future
or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right. 

  
 20 

 8.5 Notices. Any and all notices or other communications or deliveries required or
permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earliest of (a) the date of transmission, if such notice or communication is delivered via facsimile or e-mail at the facsimile number or
e-mail address referred to in this Section 8.5 prior to 5:00 p.m. (Eastern time) on a Business Day, (b) the next Business Day after the date of transmission, if such notice or communication is delivered via facsimile or e-mail at
the facsimile number or e-mail address referred to in this Section 8.5 on a day that is not a Business Day or later than 5:00 p.m. (Eastern time) on any Business Day, (c) the Business Day following the date of deposit with a nationally
recognized overnight courier service or (d) upon actual receipt by the party to whom such notice is required to be given. The addresses, facsimile numbers and e-mail addresses for such notices and communications are those set forth on the
signature pages hereof, or such other address, facsimile number or e-mail address as may be designated in writing hereafter, in the same manner, by the relevant party hereto. 

8.6 Headings. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to
limit or affect any of the provisions hereof. 
 8.7 Entire Agreement. This Agreement, together with the other Transaction
Agreements contain the entire understanding of the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, oral or written, with respect to such matters, which the parties acknowledge have been merged
into such agreements and exhibits. At or after the Closing, and without further consideration, the parties hereto will make, do and execute and deliver, or cause to be made, done and executed and delivered, such further acts, deeds, assurances,
documents and things as may be reasonably requested by any of the other parties hereto in order to give practical effect to the intention of the parties hereunder. 

8.8 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their respective
successors and permitted assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of Purchasers representing a Majority in Interest (other than by merger, consolidation or sale of
all or substantially all of the Company’s assets). A Purchaser may assign any or all of its rights under this Agreement to any Person to whom the Purchaser assigns or transfers any Securities, provided that such transferee agrees in writing to
be bound, with respect to the transferred Securities, by the provisions of this Agreement that apply to the “Purchasers.” 

8.9 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 or entity. 
 8.10
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 legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement (whether brought against a party hereto or its
respective Affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York, Borough of Manhattan. Each party hereby irrevocably submits to the
exclusive jurisdiction of the state and federal courts sitting in the City of New York, borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and
hereby irrevocably waives, and agrees 

  
 21 

 
not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an
inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or
overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained
herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law. If either party shall commence an action or proceeding to enforce any provisions of this Agreement, then the prevailing party in such action
or proceeding shall be reimbursed by the other party for its reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding. 

8.11 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 this Agreement. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in
this Agreement and hereby agree to waive and not to assert in any action for specific performance of any such obligation the defense that a remedy at law would be adequate. 

8.12 Execution. This Agreement may be executed by one or more of the parties hereto on any number of separate counterparts
(including by facsimile or e-mail transmission), all of which when taken together shall be considered one and the same agreement. In the event that any signature is delivered by facsimile transmission or e-mail attachment, 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 e-mail-attached signature page were an original thereof. 

8.13 Survival; Severability. All representations and warranties made by the Company and each of the Purchasers herein will
survive the execution of this Agreement, the Closing and the delivery to the Purchasers of the Securities being purchased and the payment therefor until the first anniversary of the Closing Date, except for those representations and warranties which
speak as of a specific date. All covenants and other agreements set forth in this Agreement shall survive the Closing for the respective periods set forth therein and if no such period is specified until the first anniversary of the Closing Date.
Notwithstanding anything to the contrary contained herein, Sections 7.1 and 8.4 shall survive for the applicable statute of limitations. 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. 
 8.14 Replacement of Certificates. If any
certificate evidencing the securities issued or issuable hereunder is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or
in lieu of and substitution therefor, a new certificate, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity or security, if requested. The applicant for
a new certificate under such circumstances shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement certificates. 

8.15 Interpretation. The parties agree that each of them and/or their respective counsel has reviewed and had an opportunity to revise
this Agreement and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the 

  
 22 

 
interpretation of this Agreement or any amendments hereto. In addition, each and every reference to share prices and shares of capital stock in this Agreement shall be subject to adjustment for
reverse and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after the date of this Agreement. The word “including”, whenever used in this Agreement, shall be deemed to
be followed by the phrase “without limitation”. 
 8.16 Independent Nature of Purchasers’ Obligations and Rights. The
obligations of each Purchaser under any Transaction Agreement are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or non-performance of the obligations of any
other Purchaser under any Transaction Agreement. Nothing contained herein or in any other Transaction Agreement, and no action taken by any Purchaser pursuant 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 Agreements. 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 Agreements, and it shall not be necessary for any other Purchaser to be joined
as an additional party in any proceeding for such purpose. Each Purchaser has been advised to retain its own representation, including its own separate legal counsel, in their review and negotiation of the Transaction Agreements.

 Exhibit 10.2 

REGISTRATION RIGHTS AGREEMENT 

This Registration Rights Agreement (this “Agreement”) is made as of November 11, 2013, among Authentidate Holding Corp.,
a Delaware corporation (the “Company”) and the parties set forth on the signature pages hereto (each, a “Purchaser” and collectively, the “Purchasers”). 

Recitals 
 WHEREAS, the
Company proposes to sell and issue shares of Common Stock and Common Stock Purchase Warrants (the “Warrants”) to the Purchasers pursuant to a Securities Purchase Agreement of even date herewith (the “Purchase
Agreement”); and 
 WHEREAS, as a condition to its investment, the Purchasers have required that the Company enter into this
Agreement with the Purchasers. 
 NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement hereby agree as follows: 

Agreement 
 1. Certain
Definitions. As used in this Agreement, the following terms shall have the following respective meanings: 

“Affiliate” of any specified Person means any other Person directly or indirectly controlling or controlled by or under
direct or indirect common control with such specified Person. For the purposes of this definition, “control”, when used with respect to any specified Person, means the power to direct the management and policies of such Person,
directly or indirectly, whether through the ownership of voting securities, by contract or otherwise; and the terms “controlling” and “controlled” have meanings correlative to the foregoing. 

“Affiliated Fund” shall mean, with respect to a Holder that is a limited liability company or a limited liability
partnership, a fund or entity managed by the same manager or managing member or general partner or management company or by an entity controlling, controlled by or under common control with such manager or managing member or general partner or
management company. 
 “Business Day” means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which
the banking institutions in the City of New York, New York are authorized or obligated by law or executive order to close or be closed. 

“Closing Date” means the Closing Date under the Purchase Agreement. 

“Commission” shall mean the United States Securities and Exchange Commission or any successor agency. 

“Common Stock” shall mean the common stock of Authentidate Holding Corp., par value $0.001 per share. 

“Exchange Act” shall mean the Securities Exchange Act of 1934, as amended. 

 “Holder” shall mean a Purchaser, and any transferee of Registrable Securities
who pursuant to Section 11 below is entitled to registration rights hereunder. 
 “Initiating Holder(s)” means
either a Holder or group of Holders of the Registrable Securities representing at least 50.1% of the then outstanding Registrable Securities (provided that at such time, such Holder or Holders represent at least 50.1% of the shares of Common Stock
sold under the Purchase Agreement). 
 “Majority Holders” means at any time Holders of at least 50.1% of the then
outstanding Registrable Securities. 
 “Person” means an individual or corporation, partnership, trust, incorporated or
unincorporated association, joint venture, limited liability company, joint stock company, government (or an agency or subdivision thereof) or other entity of any kind. 

“Registrable Securities” shall mean: (a) shares of the Common Stock issued pursuant to the Purchase Agreement; and
(b) the shares of Common Stock which may be issued upon the exercise of the Warrants issued pursuant to the Purchase Agreement; provided, however, that with respect to any particular Registrable Security, such security shall cease
to be a Registrable Security when, as of the date of determination, such security is: (i) sold pursuant to a registration statement or pursuant to Rule 144 under the Securities Act; (ii) sold in a transaction exempt from the registration
and prospectus delivery requirements of the Securities Act under Section 4(1) thereof so that all transfer restrictions and restrictive legends with respect thereto, if any, are removed upon the consummation of such sale; (iii) sold by a
person in a transaction in which rights under this Agreement are not assigned; or (iv) in the opinion of counsel to the Company, registration under the Securities Act is no longer required for subsequent public distribution of such security
without volume limitations pursuant to Rule 144 promulgated under the Securities Act, or otherwise. In the event of any merger, reorganization, consolidation, recapitalization or other change in corporate structure affecting the Common Stock, such
adjustment shall be made in the definition of “Registrable Securities” as is appropriate to prevent any dilution or increase of the rights granted hereunder as determined in good faith by the Board of Directors of the Company. 

The terms “register,” “registered” and “registration” refer to a registration effected by
preparing and filing a registration statement in compliance with the Securities Act and the declaration or ordering of the effectiveness of such registration statement. 

“Registration Expenses” shall mean all expenses incurred by the Company in complying with Sections 2 and 3
hereof, including, without limitation, all registration, qualification and filing fees, printing expenses, escrow fees, fees and disbursements of counsel for the Company, blue sky fees and expenses, and the expense of any special audits incident to
or required by any such registration, but excluding all Selling Expenses. 
 “Securities Act” shall mean the Securities Act
of 1933, as amended. 
 “Selling Expenses” shall mean all underwriting discounts, selling commissions, and stock transfer
taxes applicable to the securities registered by the Holders and any fees of counsel to any Holder (other than as allowed as a Registration Expense).

 “Series D Registrable
Securities” shall mean those securities held by the Series D Holders which are determined to be “registrable securities” in accordance with the terms and conditions of the Series D Registration Rights Agreement. 

2. Requested Registration. 

(a) Request for Registration. If, at any time after the first anniversary of the execution of this Agreement, the Company shall receive
from an Initiating Holder or Initiating Holders a written request that the Company file a registration statement under the Securities Act covering all or a part of the Registrable Securities, the Company will: 

(i) promptly (but in any event with fifteen (15) days of receiving such request) give written notice of the proposed registration to all
other Holders and all other security holders of the Company that possess registration rights granted by the Company; and 
 (ii) as soon as
practicable, use commercially reasonable efforts to file and thereafter cause to become effective, the registration under the Securities Act of all Registrable Securities that the Company was requested to register pursuant to Section 2(a) of
this Agreement such as would permit or facilitate the sale and distribution of all or any such portion of such Registrable Securities as are specified in such request, together with all or any such portion of the Registrable Securities of any Holder
or Holders joining in such request as are specified in a written request received by the Company within 20 days after receipt of such written notice from the Company and such other security holders of the Company that possess registration rights
granted by the Company, as contemplated by Section 2(a)(i); provided, however, that the Company shall not be obligated to take any action to effect any such registration pursuant to this Section 2: 

(A) in any particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting
such registration, qualification or compliance unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act; 

(B) prior to 60 days immediately following the effective date of any other registration statement pertaining to securities of the Company
(other than a registration of securities pursuant to Rule 145 promulgated under the Securities Act or with respect to an employee benefit plan); or 

(C) during the period starting with the date ninety (90) days prior to the Company’s good faith estimate of the date of filing of,
and ending on a date one hundred and eighty (180) days after the effective date of, a Company-initiated registration pursuant to Section 3 hereof; provided that at all times during any such period, the Company is actively employing
in good faith all commercially reasonable efforts to cause such registration statement to become effective. 
 (b) Subject to the foregoing
clauses, the Company shall file a registration statement covering the Registrable Securities so requested to be registered as soon as practicable after receipt of the request or requests of an Initiating Holder. If, however, the Company shall
furnish to the Holder or Holders requesting a registration statement pursuant to this Section 2 a certificate signed by the President of the Company stating that, in the good faith judgment of the Board of Directors of the Company, it
would be seriously detrimental to the Company and its stockholders for such registration 

  
 -3- 

 
statement to be filed and it is therefore essential to defer the filing of such registration statement, the Company shall have the right to defer such filing for a period of not more than 180
days after receipt of the request of the Initiating Holder or Initiating Holders; provided, however, that the Company may not utilize this right more than once in any twelve-month period, and provided, further, that the Company
shall not register any securities for the account of itself or any other stockholder during such 180-day period (other than in a registration relating solely to the sale of securities of participants in a Company stock plan, a registration relating
to a corporate reorganization or transaction under Rule 145 of the Securities Act, or a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the
sale of Registrable Securities). The Company shall not be obligated to effect more than one registration pursuant to Section 2 of this Agreement; provided that if the Initiating Holder(s) requesting a registration statement pursuant to this
Section 2 are obliged to reduce the amount of Registrable Securities included in the registration statement pursuant to Section 2(c)(i) below, the Company shall be obliged to effect more than one registration pursuant to this
Section 2 until such time that all Registrable Securities have been registered (or are no longer deemed to be Registrable Securities hereunder), subject to the limit that the Company shall not be required to effect more than two
(2) registrations pursuant to this Section 2 during any twelve (12) month period. 
 (c) Underwriting. If the
Initiating Holder or Initiating Holders, as the case may be, intend to distribute the Registrable Securities covered by its request by means of an underwriting, it shall so advise the Company as a part of such request and the Company shall include
such information in its written notice to the other Holders. The right of any Holder to registration pursuant to this Section 2(c) shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such
Holder’s Registrable Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the Initiating Holder(s) and such Holder) to the extent provided herein. The Company shall (together with all Holders proposing
to distribute their securities through such underwriting) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company (which underwriter or underwriters shall be
reasonably acceptable to a majority in interest of the Initiating Holders). 
 (i) Notwithstanding any other provision of this
Section 2, if the managing underwriter advises the Holders in writing that marketing factors require a limitation of the number of shares to be underwritten, then, the Company shall so advise all Holders and the number of shares of
Registrable Securities and other securities of the Company that may be included in the registration and underwriting shall be allocated, subject to the rights of the Series D Holders requesting to include in the registration Series D Registrable
Securities in accordance with the terms of the Series D Registration Rights Agreement, among (A) all Holders requesting inclusion in the registration in proportion, as nearly as practicable, to the respective amounts of Registrable Securities
originally requested by such Holders to be included in the Registration Statement and (B) all other security holders of the Company that possess registration rights for other securities granted by the Company. No Registrable Securities excluded
from the underwriting by reason of the underwriter’s marketing limitation shall be included in such registration. If the underwriter or underwriters has not limited the number of Registrable Securities to be underwritten, the Company may
include securities for its own account if the underwriter so agrees. 
 (ii) If any Holder of Registrable Securities disapproves of the
terms of the underwriting, such Holder may, subject to Section 4 hereof, decline to participate therein or elect to withdraw therefrom by written notice to the Company, the underwriter(s) and the other Holders. The Registrable Securities
and/or other securities so withdrawn or not participating shall be withdrawn from registration; provided, however, that if by any withdrawal of such Registrable Securities a greater number of Registrable Securities held by other
Holders, respectively, may be included in such registration (up to 

  
 -4- 

 
the maximum of any limitation imposed by the underwriters), then the Company shall offer to all Holders who have included Registrable Securities in the registration the right to include
additional Registrable Securities, in the same proportion used in determining the underwriter limitation in this Section 2(c). 

(d) Withdrawn Requests. The undersigned Holders agree that in the event the Company is requested to effect a registration pursuant to
this Section 2 by the Initiating Holder(s) and thereafter, but before the effectiveness of such registration, any Holder that either acted as the Initiating Holder or that was part of a group of Holders that acted as the Initiating Holders,
notifies the Company that it wishes to withdraw such request or to withdraw from participating in the group, then the following shall apply: (i) the Company may terminate the registration and the ability of such Holder to act as an Initiating
Holder or to participate in a group acting as the Initiating Holders shall immediately terminate or (ii) the Company may elect to continue with the registration of the Registrable Securities (excluding those of the withdrawing Holder) and such
registration shall in all respects continue to be treated as a requested registration pursuant to this Section 2. 
 3. Company
Registration. (a) Notice of Registration. If the Company shall determine to register any of its securities, either for its own account or the account of a security holder or holders exercising their respective registration rights (other
than under Section 2 hereof), other than: (i) a registration relating solely to employee benefit plans (whether effected on Form S-8 or its successor); (ii) a registration relating
to the offer and sale of debt securities; (iii) a registration relating to a corporate reorganization or other transaction under Rule 145 of the Securities Act (whether effected on Form S-4 or its
successor); or (iv) a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities, the Company will: 

(A) provide to each Holder written notice thereof at least seven days prior to the filing of the Registration Statement by the Company in
connection with such registration; and 
 (B) subject to the terms hereof, include in such registration (and any related qualification
under blue sky laws or other compliance), and in any underwriting involved therein, all the Registrable Securities specified in a written request or requests by such Holder or Holders, made within five days after the Company mails the written notice
referred to above, by any Holder or Holders (a “piggyback” registration). 
 (b) Underwriting Cut-Backs and
Allocation. In connection with any offering involving an underwriting of shares of the Company’s capital stock, the Company shall not be required under Section 3 to include any of the Holders’ Registrable Securities in such
underwriting unless they accept the terms of the underwriting as agreed upon between the Company and the underwriters selected by the Company (or by other persons entitled to select the underwriters), and then only, subject to this
Section 3(b), in such quantity as the underwriters determine in their sole discretion will not jeopardize the success of the offering by the Company. If the total amount of securities, including Registrable Securities, requested by
shareholders to be included in such offering, is in such an amount that the underwriters determine in their sole discretion is incompatible with the success of the offering, then the Company shall be required to include in the offering only that
number of such securities, including Registrable Securities, that the underwriters determine in their sole discretion will not jeopardize the success of the offering. The Company shall so advise all holders of securities requesting registration, and
the number of shares of securities that are entitled to be included in the registration and underwriting shall be allocated as follows: (i) first, to the Company for securities being sold for its own account, (ii) second, to the Series D
Holders requesting to include in the registration Series D Registrable Securities in accordance with the terms of the Series D Registration Rights Agreement, (iii) third, to the Holders requesting to include in the

  
 -5- 

 
registration Registrable Securities, based on the pro rata percentage of Registrable Securities held by such Holders and (iii) fourth, to any other securityholders on a pro
rata basis, based on the number of shares held (assuming conversion and exercise of rights to acquire capital stock). For purposes of the preceding sentence concerning apportionment, for any selling shareholder that is a holder of Registrable
Securities and that is a venture capital fund or a partnership or corporation or limited liability company or other entity, the Affiliated Funds, partners, retired partners, members, retired members, parent or subsidiary company and shareholders of
such holder, or the estates and family members of any such partners, retired partners, members, retired members and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single “selling shareholder,” and
any pro-rata reduction with respect to such “selling shareholder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “selling
shareholder,” as defined in this sentence. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the managing underwriter. Any Registrable Securities
excluded or withdrawn from such underwriting shall be withdrawn from such registration. The Holders’ right to have Registrable Securities included in the first registration statement filed by the Company may be deferred to a subsequent
registration statement filed by the Company, which deferral may be continued so long as the registration statements are pursuant to underwritten offerings and the underwriter determines in good faith that marketing factors require exclusion of some
or all of the Registrable Securities held by the Holders, but such deferral shall be only to the extent of such required exclusion as determined by the underwriter. 

(c) Other Covenants. If the registration is an underwritten registration, each Holder of Registrable Securities shall enter into an
underwriting agreement in customary form with the underwriter and provide such information regarding Holder that the underwriter shall reasonably request in connection with the preparation of the prospectus describing such offering, including
completion of FINRA Questionnaires. 
 (d) Right to Terminate Registration. The Company shall have the right to terminate or withdraw
any registration initiated by it under this Section 3 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration. 

4. Expenses of Registration. All Registration Expenses incurred in connection with any registration, qualification or compliance
pursuant to Sections 2 or 3 hereof shall be borne by the Company. All Selling Expenses relating to securities registered by the Holders shall be borne by the Holders of such securities pro rata on the basis of the number of shares
so registered. Notwithstanding the foregoing, the Company shall not be required to pay for Registration Expenses pursuant to Section 2 if the registration request is subsequently withdrawn at the request of the Initiating Holders (which
Holders shall bear such expenses); provided, however, that if at the time of such withdrawal, the Holders have learned of a material adverse change in the condition, business or prospects of the Company from that known to the Holders at the time of
their request, then the Holders shall not be required to pay any of such Registration Expenses. If the Company shall withdraw a registration initiated under Section 3, the expenses of such withdrawn registration shall be borne by the
Company. 
 5. Registration Procedures. In the case of each registration, qualification, or compliance effected by the Company
pursuant to this Agreement, the Company will keep each Holder advised in writing as to the initiation of such registration, qualification, and compliance and as to the completion thereof. In connection with any registration effected pursuant to this
Agreement, the Company will prepare and file such amendments and supplements to its registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such
registration statement. At its expense the Company will furnish such number of prospectuses and 

  
 -6- 

 
other documents incident thereto as a Holder from time to time may reasonably request. In connection with any registration effected pursuant to this Agreement, the Company shall also (to the
extent not otherwise expressly required pursuant to this Agreement): 
 (a) Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its commercially reasonable efforts to cause such registration statement to become effective, and keep such registration statement continuously effective for a period that will terminate upon the
earlier of (i) the date on which the distribution described in such registration statement is completed, and (ii) the date on which all Registrable Securities covered by such registration statement may be sold without any restrictions
pursuant to Rule 144 (the “Effectiveness Period”); provided, however, that (i) the Effectiveness Period shall be extended for a period of time equal to: (A) the period the Holder refrains from selling any
securities included in such registration at the request of an underwriter of Common Stock (or other securities) of the Company; or (B) the period beginning with the Holder’s receipt of the notice described in Section 5(d) below
and ending when the Company furnishes the amendment described in Section 5(d) to the Holders, and (ii) in the case of any registration of Registrable Securities on Form S-3 that are intended
to be offered on a continuous or delayed basis, the Effectiveness Period shall be extended, if necessary, to keep the registration statement effective until all such Registrable Securities are sold, provided that Rule 415, or any successor rule
under the Securities Act, permits an offering on a continuous or delayed basis, and provided further that applicable rules under the Securities Act governing the obligation to file a post-effective amendment permit, in lieu of filing a
post-effective amendment that (x) includes any prospectus required by Section 10(a)(3) of the Securities Act or (y) reflects facts or events representing a material or fundamental change in the information set forth in the
registration statement, the incorporation by reference of information required to be included in (x) and (y) above to be contained in periodic reports filed pursuant to Section 13 or 15(d) of the Exchange Act in the registration
statement. 
 (b) Prepare and file with the SEC such amendments and supplements to such registration statement (including post-effective
amendments) and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement for
the Effectiveness Period and if a registration statement is subject to review by the SEC, promptly respond to all comments and diligently pursue resolution of any comments to the satisfaction of the SEC. 

(c) Use commercially reasonable efforts to register and qualify the securities covered by such registration statement under such other
securities or blue sky laws of such jurisdictions as shall be reasonably requested by the Holders and to do any and all other acts and things which may be reasonably necessary or advisable to enable such Holder to consummate the disposition in such
jurisdictions of the Registrable Securities owned by such Holder; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions (unless the Company is already qualified to do business or subject to service of process in that jurisdiction and except as may be required by the Securities Act). 

(d) Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. As promptly as practicable thereafter, the Company will prepare and file with the SEC, and
furnish without charge to the appropriate Holders and managing underwriter(s), if any, 

  
 -7- 

 
an amendment or supplement to such registration statement or prospectus in order to cause such registration statement or prospectus not to include any untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and will furnish such copies thereof as the Holders or any underwriters may reasonably
request. 
 (e) Furnish to the Holders, without charge, such number of copies of a prospectus, including a preliminary prospectus and any
supplements or amendments thereto, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them. 

(f) Otherwise use commercially reasonable efforts to comply, during the period that such registration statement is effective under the
Securities Act, in all material respects with the Securities Act and the Exchange Act and with all applicable rules and regulations of the SEC with respect to the disposition of all securities covered by such registration statement, and make
available to its security holders, as soon as reasonably practicable, an earnings statement covering a period of at least twelve (12) months, beginning after the effective date of each registration statement, which earnings statement shall
satisfy the provisions of Section 11(a) of the Securities Act. 
 (g) Use commercially reasonable efforts to (i) prevent the
issuance of any stop order or other suspension of effectiveness and (ii) if such order is issued, (A) notify each Holder of Registrable Securities being offered or sold pursuant to such registration statement as promptly as practicable
after becoming aware of the issuance by the SEC of any stop order or other suspension of effectiveness of the registration statement at the earliest possible time and (B) obtain the withdrawal of any such order at the earliest possible moment.

 (h) Permit the Holders of Registrable Securities being included in such registration statement and their legal counsel, at such
Holders’ sole cost and expense (except as otherwise specifically provided in this Agreement), to review and have a reasonable opportunity to comment on the registration statement and all amendments and supplements thereto at least three
(3) Business Days prior to their filing with the SEC. 
 (i) In the event of any underwritten public offering, enter into and perform
its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter(s) of such offering. Each Holder participating in such underwriting shall also enter into and perform its obligations under such an
agreement. 
 (j) Use commercially reasonable efforts to cause all such Registrable Securities registered pursuant to this Agreement to be
listed on each national securities exchange or trading system on which similar securities issued by the Company are then listed. 
 (k)
Cooperate with the Holders of Registrable Securities being offered pursuant to such registration statement to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be offered pursuant to such
registration statement and enable such certificates to be in such denominations or amounts as the Holders may reasonably request and registered in such names as the Holders may request.

 6. Covenants with Respect to Registration. In connection with the registration in which
the Registrable Securities are included, the Company and each Holder covenant and agree as follows: 
 (a) The foregoing registration rights
shall be contingent on the Holders furnishing the Company with such appropriate information as the Company shall reasonably request, including (A) such information regarding itself, the Registrable Securities held by it and the intended method
of disposition of the Registrable Securities held by it, as shall be reasonably required to effect the registration of such Registrable Securities and shall execute such documents in connection with such registration as the Company may reasonably
request. At least seven days prior to the first anticipated filing date of any Registration Statement, the Company shall notify each Holder of the information the Company requires from such Holder if such Holder elects to have any of the Registrable
Securities included in the Registration Statement. A Holder shall provide such information to the Company at least two (2) Business Days prior to the first anticipated filing date of such Registration Statement if it elects to have any of the
Registrable Securities included in the Registration Statement. Each Holder agrees to furnish to the Company a completed selling security holder questionnaire (a “Questionnaire”) in the form provided to it by the Company not less
than two Business Days prior to the filing date of such Registration Statement. The Company shall not be required to include the Registrable Securities of a Holder in a Registration Statement and shall not be required to pay any damages to such
Holder who fails to furnish to the Company a fully completed Questionnaire at least two Business Days prior to the filing date. The Company may require each selling Holder to furnish to the Company a certified statement as to the number of shares of
Common Stock beneficially owned by it and, if required by the Commission, the natural persons thereof that have voting and dispositive control over its shares of Common Stock. 

(b) Each Holder, by its acceptance of the Registrable Securities agrees to cooperate with the Company as reasonably requested by the Company
in connection with the preparation and filing of a Registration Statement hereunder, unless such Holder has notified the Company in writing of its election to exclude all of its Registrable Securities from such Registration Statement. Each Holder
agrees that, upon receipt of any notice from the Company that it must suspend sales of Common Stock pursuant to the Registration Statement, it will immediately discontinue disposition of Registrable Securities pursuant to the Registration Statement
covering such Registrable Securities, until the Holder is advised by the Company that such dispositions may again be made. 
 (c) Each
Holder covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it in connection with sales of Registrable Securities pursuant to a Registration Statement. 

(d) Rule 415; Cutback. If at any time the SEC takes the position that the offering of some or all of the Registrable Securities in a
registration statement filed pursuant to Section 2 or 3 hereof is not eligible to be made on a delayed or continuous basis under the provisions of Rule 415 under the Securities Act or requires any Holder to be named as an
“underwriter”, if the Company believes, in its discretion and upon the advice of counsel, that the Registrable Securities are eligible for registration under Rule 415 or that such Holder is not an “underwriter” for the purposes
of the Securities Act and the registration, the Company shall use commercially reasonable efforts to persuade the SEC that the offering contemplated by the registration statement is a valid secondary offering and not an offering by or on behalf of
the issuer for the purposes of Rule 415 and that such Holder is not an “underwriter.” Such Holder shall provide to the Company in writing all information requested by the Company to support such Holder’s contention that it is not an
“underwriter.” Such Holder shall have the right to participate or have its counsel participate in any meetings or discussions with the SEC regarding the SEC’s position (unless in the reasonable opinion of the Company or its counsel,
such participation will be to the detriment to the Company in that it may cause undue delays in the registration process or for other reasons) and to comment or have their counsel comment on any written submission made to the SEC with respect
thereto. No such written submission regarding the foregoing specifying a Holder shall be made to the SEC to which the Holders’ counsel reasonably objects. The Company shall not agree to name any

  
 -9- 

 
Holder as an “underwriter” in such registration statement without the prior written consent of such Holder. In the event that, despite the Company’s reasonable best efforts and
compliance with the terms of this Section, the SEC refuses to alter its position, the Company shall (i) remove from the registration statement such portion of the Registrable Securities (the “Cut Back Shares”) and/or
(ii) agree to such restrictions and limitations on the registration and resale of the Registrable Securities, in each case as the SEC may require to assure the Company’s compliance with the requirements of Rule 415 (collectively, the
“SEC Restrictions”). Upon the SEC’s initial declaration that the Registration Statement is effective, the Company shall no longer have any obligations under this Agreement to register the Cut Back Shares. 

(e) Each Holder agrees that, upon receipt of any notice from the Company of either (i) the commencement of an Allowed Delay (as defined
below) or (ii) the happening of an event pursuant to Section 5(d) hereof, such Holder will immediately discontinue disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities, until the
Holder is advised by the Company that such dispositions may again be made. The Company may suspend the use of any prospectus included in any Registration Statement contemplated by this Agreement in the event that the Company determines in good faith
that the suspension of the use of any prospectus is necessary to (A) delay the disclosure of material non-public information concerning the Company, the disclosure of which at the time is not, in the good faith opinion of the Company, in the
best interests of the Company or (B) amend or supplement the affected Registration Statement or the related prospectus so that such Registration Statement or prospectus shall not include 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 the prospectus in light of the circumstances under which they were made, not misleading (an “Allowed Delay”); provided,
that the Company shall promptly (a) notify each Holder in writing of the suspension of and the reasons for such suspension, but shall not (without the prior written consent of a Holder) disclose to such Holder any material non-public
information giving rise to an Allowed Delay, (b) advise the Holders in writing to cease all sales under the Registration Statement until the end of the Allowed Delay and (c) use reasonable best efforts to terminate such suspension as
promptly as practicable. 
 7. Termination of Registration Rights. The registration rights granted pursuant to this Agreement shall
terminate on the earlier of: (i) four (4) years after the closing of the sale by the Company of the shares of Common Stock and Warrants pursuant to the Purchase Agreement; or (ii) as to any Holder, at such time as Rule 144 or
another similar exemption is available for the sale without restriction or limitation of all of such Holder’s (together with any person with whom such Holder is required to aggregate sales under Rule 144) shares. At such time as a Holder may
resell its Registrable Securities without restriction (within the scope of clause (ii) of this Section 7, the Registrable Securities held by such Holder will not be considered “then outstanding shares of Registrable
Securities” and the consent of such Holder shall not be counted for purposes of obtaining the majority consent required for purposes of amending this Agreement pursuant to Section 12(e). 

8. Lock-up Agreement. (a) In consideration for the Company agreeing to its obligations under this Agreement, each Holder of Registrable
Securities and each transferee pursuant to Section 11 hereof agrees, in connection with a registration of the Company’s securities under the Securities Act, upon request of the Company or the underwriters managing any underwritten
offering of the Company’s securities, not to: (i) lend, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise
transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (whether such shares or any such securities are then owned by the Holder or are thereafter
acquired); or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (i) or
(ii) above is to be settled by 

  
 -10- 

 
delivery of Common Stock or such other securities, in cash or otherwise, without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to
exceed 180 days from the effective date of such registration statement, the “Lock-up Period”) as may be requested by the Company or such managing underwriters; provided that if (A) the Company issues an earnings release
or material news, or a material event relating to the Company occurs, during the last 17 days of the Lock-up Period, or (B) prior to the expiration of the Lock-up Period, the Company announces that it will release earnings results during the
16-day period beginning on the last day of the Lock-up Period, the restrictions imposed by this agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the
material news or material event to allow any managing underwriter to comply with FINRA Rule 2711(f)(4) (or any comparable rule subsequently adopted by the Financial Industry Regulatory Authority). In no event, however, will the restricted period
extend beyond 215 days after the effective date of the registration statement. Each Holder further agrees to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of an underwritten public offering. Each
Holder agrees that the Company may instruct its transfer agent to place stop-transfer notations in its records to enforce the provisions of this Section 8 until the end of such period. This Section 8 shall supersede any
conflicting provision of Section 2 or Section 3 above. 
 (b) The foregoing obligations described in this
Section 8 shall not apply to a registration relating solely to employee benefit plans, or to a registration relating solely to a transaction pursuant to Rule 145 under the Securities Act. Any release of any person from the lock up
restrictions, at any time during the market stand-off time period, shall be done pro rata among the Holders of Registrable Securities, so that each Holder of Registrable Securities may sell, transfer or otherwise dispose of an equal
percentage of his, her or its shares originally subject to the lock-up restrictions. If any person described in this Section 8(b) is released from the agreements referenced therein, the Holders of Registrable Securities shall be released
to the same extent from the lockup agreements described in Section 8(a). 
 9. Indemnification. In the event any
Registrable Securities are included in a registration statement under this Agreement: 
 (a) To the extent permitted by law, the Company
will indemnify each Holder, each of its officers, directors and partners and such Holder’s legal counsel and independent accountants, and each person controlling such Holder within the meaning of Section 15 of the Securities Act, with
respect to which registration, qualification or compliance has been effected pursuant to this Agreement, against all expenses, claims, losses, damages and liabilities (or actions in respect thereof), including any of the foregoing incurred in
settlement of any litigation, commenced or threatened, arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, offering circular or other document, or any
amendment or supplement thereto, incident to any such registration, qualification or compliance, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances in which they were made, not misleading, or any violation or alleged violation by the Company of the Securities Act or the Exchange Act or the securities laws of any state or any rule or regulation thereunder,
and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance, and will reimburse each such Holder, each of its officers, directors and partners and such Holder’s legal counsel
and independent accountants, and each person controlling such Holder, for any legal and any other expenses reasonably as incurred in connection with investigating, preparing or defending any such claim, loss, damage, liability or action;
provided, however, that (i) in the event that any amounts reimbursed by the indemnifying party hereunder are determined by a final, non-appealable judgment by a court or arbitral tribunal, to have resulted primarily from an
indemnified party’s gross negligence, bad faith or willful misconduct, such indemnified 

  
 -11- 

 
party shall promptly repay such amounts to the indemnifying party and (ii) the Company shall not be liable in any case to the extent that any such claim, loss, damage, liability or expense
arises out of or is based on any untrue statement or omission or alleged untrue statement or omission, made in reliance upon and in conformity with information furnished to the Company by such Holder; and provided further, that the
Company will not be liable to any such person or entity with respect to any such untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus that is corrected in the final prospectus filed with the
Commission pursuant to Rule 424(b) promulgated under the Securities Act (or any amendment or supplement to such prospectus) if the person asserting any such loss, claim, damage or liability purchased securities but was not sent or given a copy
of the prospectus (as amended or supplemented) at or prior to the written confirmation of the sale of such securities to such person in any case where such delivery of the prospectus (as amended or supplemented) is required by the Securities Act,
unless such failure to deliver the prospectus (as amended or supplemented) was a result of the Company’s failure to provide such prospectus (as amended or supplemented). Notwithstanding the foregoing, the indemnity agreement contained in this
Section 9(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld). 

(b) Each Holder will, severally and not jointly, indemnify and hold harmless the Company, each of its directors and officers and its legal
counsel and independent accountants, each underwriter, if any, of the Company’s securities covered by such a registration statement, each person who controls the Company or such underwriter within the meaning of Section 15 of the
Securities Act, and each other such Holder, each of its officers, directors and partners and each person controlling such Holder within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or
actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or other document, or any omission (or alleged
omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company, such other Holders, such directors, officers, legal counsel, independent
accountants, underwriters or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent,
that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with information furnished to the
Company by such Holder; provided, however, that the obligations of such Holders hereunder shall be limited to an amount equal to the gross proceeds to each such Holder of Registrable Securities sold as contemplated herein, except in
the case of fraud or willful misconduct by such Holder. Such indemnity shall remain in full force and effect, regardless of any investigation by or on behalf of the Company or any such director, officer or controlling Person and shall survive the
transfer of such securities by such Holder. 
 (c) Each party entitled to indemnification under this Section 9 (the
“Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided, however, that counsel for the Indemnifying Party, who shall conduct the defense of such claim or
litigation, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld) and the Indemnified Party may participate in such defense at such Indemnified Party’s expense; provided, however, that an
Indemnified Party shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnifying Party, if representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate
due to actual or potential conflict of interests between such Indemnified Party and any other party (including the 

  
 -12- 

 
Indemnifying Party) represented by such counsel in such proceeding. The failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its
obligations under this Agreement, except to the extent, but only to the extent, that the Indemnifying Party’s ability to defend against such claim or litigation is actually prejudiced as a result of such failure to give notice. No Indemnifying
Party in the defense of any such claim or litigation shall, except with the consent of each Indemnified Party, which consent shall not be unreasonably withheld, consent to entry of any judgment or enter into any settlement that does not include as
an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. 

(d) If the indemnification provided for in this Section 9 is held by a court of competent jurisdiction to be unavailable to an
Indemnified Party with respect to any loss, liability, claim, damage or expense referred to therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with
the statements or omissions that resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations, provided, however, that the obligations of such Holders hereunder shall be limited to
an amount equal to the total proceeds to each such Holder of Registrable Securities sold as contemplated herein, except in the case of fraud or willful misconduct by such Holder. The relative fault of the Indemnifying Party and of the Indemnified
Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified
Party and such parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 

(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with an underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control. 

(f) The obligations of the Company and Holders under this Section 9 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Agreement and the termination of this Agreement. 
 10. Information by
Holder. The Holder or Holders of Registrable Securities included in any registration shall furnish to the Company such information regarding such Holder or Holders and the distribution proposed by such Holder or Holders as the Company may
request in writing and as shall be required in connection with any registration, qualification or compliance referred to in this Agreement. 

11. Transfer of Rights. The rights granted hereunder to cause the Company to register securities may be assigned to a transferee

limited liability company. 
 12. General Provisions. (a) Aggregation. For the purposes of this Agreement, the number of
shares of Registrable Securities held by a Holder shall include the holdings of its Affiliates, and such holdings shall be aggregated together. 

(b) Governing Law. This Agreement shall be governed by and interpreted in accordance with the laws of the State of New York,
without giving effect to principles of conflicts of laws. 
 (c) Entire Agreement. This Agreement constitutes the full and
entire understanding among the parties regarding the subject matter hereof and supersedes all prior agreements and understandings between them or any of them as to such subject matter. 

(d) Notices. All notices and other communications required or permitted hereunder shall be in writing and shall be mailed by
registered or certified mail, postage prepaid, or otherwise delivered by hand or by messenger, addressed: (a) if to a Holder, to such Holder’s address as set forth in the books and records of the Company or to such other address as such
Holder shall have furnished to the Company in writing; (b) if to any other person or entity who may become a Holder pursuant to this Agreement, to such address as such person or entity shall have furnished the Company in writing, or, until any
such holder or entity so furnishes an address to the Company, then to the address of the last holder of such Registrable Securities who has so furnished an address to the Company; (c) if to the Company, to its principal executive offices, as

(e) Amendment and Waivers. Any provision of this Agreement may be amended, waived or modified upon the written consent of:
(a) the Company and (b) the Majority Holders; provided, however, that the foregoing notwithstanding, the rights of any individual Holder shall not be amended or waived without the prior written consent of such holder if such
amendment or waiver (a) is adverse to such holder in a manner that differs from how similarly situated holders of Registrable Securities are affected or (b) reduces or alters the rights of any Holder vis-à-vis any other Holder. Any
Holder may waive any of his or her rights or the Company’s obligations hereunder without obtaining the consent of any other Holder; provided, however that any such waiver on any party’s part of any breach, default or noncompliance under
the Agreement or any waiver on such party’s part of any provisions or conditions of this Agreement must be in writing and shall be effective only to the extent specifically set forth in such writing. The Company shall give prompt written notice

 -14- 

 
waiver. It is agreed that no delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under this Agreement shall
impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of any similar breach, default or noncompliance thereafter occurring. All remedies, either
under this Agreement, by law or otherwise afforded to any party, shall be cumulative and not alternative. 
 (f)
Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original and all of which together shall constitute one instrument.

connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any
such court, that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or
proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good
and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law. If either party shall commence an action or proceeding to enforce any
provisions of this Agreement, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and
prosecution of such action or proceeding. 
 (i) Adjustments for Stock Splits, Etc. Wherever in this Agreement there is a
reference to a specific number of shares of Common Stock or preferred stock of the Company of any class or series, then, upon the occurrence of any subdivision, combination or stock dividend of such class or series of stock, the specific number of
shares so referenced in this Agreement shall automatically be proportionately adjusted to reflect the effect on the outstanding shares of such class or series of stock by such subdivision, combination or stock dividend.

transaction in which the Common Stock is converted into the equity securities of another entity, the agreements executed by the Company shall expressly provide that (and such transaction shall be conditioned upon the inclusion of the following
provisions) from and after the effective time of such transaction: (i) such entity shall assume, and by virtue of such transaction be deemed to have assumed, the obligations of the Company hereunder, (ii) the term “Company” shall
be deemed to refer to such entity, and (iii) the term “Registrable Securities” shall be deemed to include the securities received by the Holders in connection with such transaction unless such securities are otherwise freely tradable
