 (a) On or prior to the Filing Deadline, the Company shall prepare and file with the Commission a Registration Statement covering the resale of all of the Registrable Securities not already covered by an
existing and effective Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415 or, if Rule 415 is not available for offers and sales of the Registrable Securities, by such other means of distribution of
Registrable Securities as the Holders may reasonably specify (the “Initial Registration Statement”). The Initial Registration Statement shall be on Form S-1 (or such other form available to register for resale the Registrable
Securities as a secondary offering) subject to the provisions of Section 2(e) and shall contain (except if otherwise required pursuant to written comments received from the Commission upon a review of such Registration Statement) a “Plan
of Distribution” section substantially in the form attached hereto as Annex A (which may be modified to respond to comments, if any, provided by the Commission). Notwithstanding the registration obligations set forth in this
Section 2 , in the event the Commission informs the Company that all of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering on a single registration statement,
the Company agrees to promptly (i) inform each of the Holders thereof and use its commercially reasonable efforts to file amendments to the Initial Registration Statement as required by the Commission and/or (ii) withdraw the Initial
Registration Statement and file a new registration statement (a “New Registration Statement”), in either case covering the maximum number of Registrable Securities permitted to be registered by the Commission, on Form S-1 or
such other form available to register for resale the Registrable Securities as a secondary offering; provided, however, that prior to filing such amendment or New Registration Statement, the Company shall be obligated to use its commercially
reasonable efforts to advocate with the Commission for the registration of all of the Registrable Securities in accordance with SEC Guidance, including without limitation, the Manual of Publicly Available Telephone Interpretations D.29 and
Compliance and Disclosure Interpretations. Notwithstanding any other provision of this Agreement and subject to the payment of liquidated damages in Section 2(c), if any SEC Guidance sets forth a limitation of the number of Registrable
Securities permitted to be registered on a particular Registration Statement as a secondary 

  
 4 

 
offering (and notwithstanding that the Company used commercially reasonable efforts to advocate with the Commission for the registration of all or a greater number of Registrable Securities),
unless otherwise directed in writing by a Holder as to its Registrable Securities, the number of Registrable Securities to be registered on such Registration Statement will first be reduced by Registrable Securities not acquired pursuant to the
Purchase Agreement (whether pursuant to registration rights or otherwise), second by Registrable Securities represented by Holders of Warrant Shares (applied, in the case that some Warrant Shares may be registered, to the Holders on a pro rata basis
based on the total number of unregistered Warrant Shares held by such Holders) and third by Registrable Securities represented by Shares (applied, in the case that some Shares may be registered, to the Holders on a pro rata basis based on the total
number of unregistered Shares held by such Holders, subject to a determination by the Commission that certain Holders must be reduced first based on the number of Shares held by such Holders). In the event the Company amends the Initial Registration
Statement or files a New Registration Statement, as the case may be, under clauses (i) or (ii) above, the Company will use its commercially reasonable efforts to file with the Commission, as promptly as allowed by Commission or SEC
Guidance provided to the Company or to registrants of securities in general, one or more registration statements on Form S-1 or such other form available to register for resale those Registrable Securities that were not registered for resale on the
Initial Registration Statement, as amended, or the New Registration Statement (the “Remainder Registration Statements”). 
 (b) The Company shall use its commercially reasonable efforts to cause each Registration Statement or any post-effective amendment thereto to be declared effective by the Commission as soon as practicable
and, with respect to the Initial Registration Statement or the New Registration Statement, as applicable, no later than the Effectiveness Deadline (including, with respect to the Initial Registration Statement or the New Registration Statement, as
applicable, filing with the Commission a request for acceleration of effectiveness in accordance with Rule 461 promulgated under the Securities Act within five (5) Business Days after the date that the Company is notified (orally or in writing,
whichever is earlier) by the Commission that such Registration Statement will not be “reviewed,” or not be subject to further review and the effectiveness of such Registration Statement may be accelerated), and, subject to Sections 2(e)
and (f), shall use its commercially reasonable efforts to keep each Registration Statement continuously effective under the Securities Act until the earlier of (i) such time as all of the Registrable Securities covered by such Registration
Statement have been publicly sold by the Holders or (ii) the date that is one (1) year following the Closing Date (the “Effectiveness Period”). The Company shall promptly notify the Holders via facsimile or electronic mail
of the effectiveness of a Registration Statement or any post-effective amendment thereto on or before the first Trading Day after the date that the Company telephonically confirms effectiveness with the Commission. The Company shall, by 9:30 a.m.
New York City time on the first Trading Day after the Effective Date, file a final Prospectus with the Commission, as required by Rule 424(b). 
 (c) If: (i) the Initial Registration Statement is not filed with the Commission on or prior to the Filing Deadline, (ii) the Initial Registration Statement or the New Registration Statement, as
applicable, is not declared effective by the Commission (or otherwise does not become effective) for any reason on or prior to the Effectiveness Deadline or (iii) after its Effective Date and except for the reasons as set forth in Sections 2(e)
and (f) and Section 3(h), (A) such Registration Statement ceases for any reason (including, without limitation, by reason of a stop order or the Company’s failure to update the Registration Statement), to remain continuously
effective as to all Registrable Securities included in such Registration Statement or (B) the Holders are not permitted to utilize the Prospectus therein to resell such Registrable Securities for any reason (other than due to a change in the
“Plan of Distribution” or the inaccuracy of any information regarding the Holders), in each case, for more than an aggregate of 20 consecutive calendar days or 45 calendar days (which need not be consecutive days) during any 12-month
period (other than as a result of a breach of this Agreement by a Holder, due to a circumstance set forth in Section 2(f) below or a Holder’s failure to return a Selling Stockholder Questionnaire within the

  
 5 

 
time period provided by Section 2(d) hereof), and (iv) the Company fails to satisfy the current public information requirement pursuant to Rule 144(c)(1) as a result of which the
Holders who are not affiliates are unable to sell Registrable Securities without restriction under Rule 144 (or any successor thereto), (any such failure or breach in clauses (i) through (iv) above being referred to as an
“Event,” and, for purposes of clauses (i), (ii) or (iv), the date on which such Event occurs, or for purposes of clause (iii), the date on which such 20 or 45 calendar day period is exceeded, being referred to as an “Event
Date”), then in addition to any other rights the Holders may have hereunder or under applicable law: (x) within five Business Days after an Event Date relating to a failure in clause (i) only, the Company shall pay to each Holder
an amount in cash, as liquidated damages and not as a penalty, equal to 1.0% of the aggregate purchase price paid by such Holder pursuant to the Purchase Agreement for any Registrable Securities held by such Holder on such Event Date; and
(y) on each 30-day anniversary (or pro rata portion thereof) following any Event Date (including, for the avoidance of doubt, a failure in clause (i), in which case each 30-day anniversary shall be measured commencing on the 31st day following such Event Date) until the earlier of (1) the
applicable Event is cured or (2) the Registrable Securities are eligible for resale pursuant to Rule 144 without manner of sale or volume restrictions, the Company shall pay to each Holder an amount in cash, as liquidated damages and not
as a penalty, equal to 1.0% of the aggregate purchase price paid by such Holder pursuant to the Purchase Agreement for any unregistered Registrable Securities then held by such Holder. The amounts payable pursuant to the foregoing clauses
(x) and (y) are referred to collectively as “Liquidated Damages.” The parties agree that (1) the Company will not be liable for Liquidated Damages under this Agreement with respect to any Warrant Shares prior to their
issuance, (2) notwithstanding anything to the contrary herein or in the Purchase Agreement, no Liquidated Damages shall be payable with respect to any period after the expiration of the Effectiveness Period (except in respect of an Event
described in Section 2(c)(iv) herein) and in no event shall the aggregate amount of Liquidated Damages (excluding Liquidated Damages payable in respect of an Event described in Section 2(c)(iv) herein) payable to a Holder exceed, in the
aggregate, 4% of the aggregate purchase price paid by such Holder pursuant to the Purchase Agreement (8% if the only Event is clause (iv)) and (3) in no event shall the Company be liable in any 30-day period for Liquidated Damages under this
Agreement in excess of 1.0% of the aggregate purchase price paid by the Holders pursuant to the Purchase Agreement. If the Company fails to pay any Liquidated Damages pursuant to this Section 2(c) in full within five Business Days after the
date payable, the Company will pay interest thereon at a rate of 1.5% per month (or such lesser maximum amount that is permitted to be paid by applicable law) to the Holder, accruing daily from the date such Liquidated Damages are due until
such amounts, plus all such interest thereon, are paid in full. Unless otherwise specified in Section 2(c), the Liquidated Damages pursuant to the terms hereof shall apply on a daily pro-rata basis for any portion of a month prior to the cure
of an Event, except in the case of the first Event Date. Notwithstanding the foregoing, nothing shall preclude any Holder from pursuing or obtaining any available remedies at law, specific performance or other equitable relief with respect to this
Section 2(c) in accordance with applicable law. The Company shall not be liable for Liquidated Damages under this Agreement as to any Registrable Securities which are not permitted by the Commission to be included in a Registration Statement
due solely to SEC Guidance from the time that it is determined that such Registrable Securities are not permitted to be registered until such time as the provisions of this Agreement as to the Remainder Registration Statements required to be filed
hereunder are triggered, in which case the provisions of this Section 2(c) shall once again apply, if applicable. In such case, the Liquidated Damages shall be calculated to only apply to the percentage of Registrable Securities which are
permitted in accordance with SEC Guidance to be included in such Registration Statement. The Effectiveness Deadline for a Registration Statement shall be extended without default or Liquidated Damages hereunder in the event that the Company’s
failure to obtain the effectiveness of the Registration Statement on a timely basis results from the failure of a Purchaser to timely provide the Company with information requested by the Company and necessary to complete the Registration
Statement in accordance with the requirements of the Securities Act (in which the Effectiveness Deadline would be extended with respect to Registrable Securities held by such Purchaser). 

  
 6 

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

(e) The Company shall (i) initially register the resale of the Registrable Securities on Form S-1 and (ii) if the Company
becomes eligible to use Form S-3 and has ongoing registration obligations hereunder, the Company has the option to undertake to register the Registrable Securities on Form S-3 after such form is available pursuant to a post-effective amendment to
Form S-1 on Form S-3, provided that if the Company exercises such option, the Company shall have a period of up to 75 days between the filing of a post-effective amendment to register the Registrable Securities on Form S-3 and the time
that the Registration Statement covering the Registrable Securities has been declared effective by the Commission, which time period shall not be considered an “Event” hereunder and no Liquidated Damages shall accrue or be payable with
respect thereto. 
 (f) Notwithstanding any provision of this Agreement to the contrary, any time period commencing with the
filing of a post-effective amendment to a Registration Statement and continuing until the time that such Registration Statement has been declared effective by the Commission shall not be considered an “Event” hereunder and no Liquidated
Damages shall accrue or be payable with respect thereto. 
 3. Registration Procedures. 

In connection with the Company’s registration obligations hereunder, the Company shall: 

(a) Not less than five Trading Days prior to the filing of each Registration Statement and not less than one Trading Day prior to the
filing of any related Prospectus or any amendment or supplement thereto (except for Annual Reports on Form 10-K, and Quarterly Reports on Form 10-Q and Current Reports on Form 8-K and any similar or successor reports), (i) furnish to the Holder
copies of such Registration Statement, Prospectus or amendment or supplement thereto, as proposed to be filed, which documents will be subject to the review of such Holder (it being acknowledged and agreed that if a Holder does not object to or
comment on the aforementioned documents within such five Trading Day or one Trading Day period, as the case may be, then the Holder shall be deemed to have consented to and approved the use of such documents) and (ii) use commercially
reasonable efforts to cause its officers and directors, counsel and independent registered public accountants to respond to such inquiries as shall be 

  
 7 

 
necessary, in the reasonable opinion of respective counsel to each Holder, to conduct such review. The Company shall not file any Registration Statement or Prospectus or any amendment or
supplement thereto in a form to which a Holder reasonably objects in good faith, provided that, the Company is notified of such objection in writing within the five Trading Day or one Trading Day period described above, as applicable. 

(b) (i) Subject to Section 2(e) and (f) and Section 3(h), prepare and file with the Commission such amendments (including
post-effective amendments) and supplements to each Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement continuously effective as to the applicable Registrable Securities for
its Effectiveness Period; (ii) cause the related Prospectus to be amended or supplemented by any required Prospectus supplement (subject to the terms of this Agreement), and, as so supplemented or amended, to be filed pursuant to Rule 424;
(iii) respond as promptly as reasonably practicable to any comments received from the Commission with respect to each Registration Statement or any amendment thereto and, as promptly as reasonably possible, provide the Holders true and complete
copies of all correspondence from and to the Commission relating to such Registration Statement that pertains to the Holders as “Selling Stockholders” but not any comments that would result in the disclosure to the Holders of material and
non-public information concerning the Company; and (iv) comply with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by a Registration Statement until such time as
all of such Registrable Securities cease to be Registrable Securities or shall have been disposed of (subject to the terms of this Agreement) in accordance with the intended methods of disposition by the Holders thereof as set forth in such
Registration Statement as so amended or in such Prospectus as so supplemented; provided, however, that each Purchaser shall be responsible for the delivery of the Prospectus to the Persons to whom such Purchaser sells any of the Shares or the
Warrant Shares (including in accordance with Rule 172 under the Securities Act), and each Purchaser agrees to dispose of Registrable Securities in compliance with the “Plan of Distribution” described in the Registration Statement and
otherwise in compliance with applicable federal and state securities laws. In the case of amendments and supplements to a Registration Statement which are required to be filed pursuant to this Agreement (including pursuant to this Section 3(b))
by reason of the Company filing a report on Form 10-K, Form 10-Q or Form 8-K or any analogous report under the Exchange Act, the Company shall have incorporated such report by reference into such Registration Statement, if applicable, or shall file
such amendments or supplements with the Commission on the same day on which the Exchange Act report which created the requirement for the Company to amend or supplement such Registration Statement was filed. 

(c) Notify the Holders (which notice shall, pursuant to clauses (iii) through (v) hereof, be accompanied by an instruction to
suspend the use of the Prospectus until the requisite changes have been made) as promptly as reasonably practicable via facsimile or electronic mail (and, in the case of (i)(A) below, not less than one (1) Trading Day prior to such filing) and
no later than one Trading Day following the day: (i)(A) when a Prospectus or any Prospectus supplement or post-effective amendment to a Registration Statement is proposed to be filed; (B) when the Commission notifies the Company whether there
will be a “review” of such Registration Statement or post-effective amendment and whenever the Commission comments in writing on any Registration Statement or any post-effective amendment thereto (in which case the Company shall provide to
each of the Holders true and complete copies of all comments that pertain to the Holders as a “Selling Stockholder” or to the “Plan of Distribution” and all written responses thereto, but not information that the Company believes
would constitute material and non-public information); and (C) with respect to each Registration Statement or any post-effective amendment thereto, when the same has become effective; (ii) of any request by the Commission or any other
Federal or state governmental authority for amendments or supplements to a Registration Statement or Prospectus or for additional information that pertains to the Holders as “Selling Stockholders” or the “Plan of Distribution”;
(iii) of the issuance by the Commission or any other federal 

  
 8 

 
or state governmental authority of any stop order suspending the effectiveness of a Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings
for that purpose; (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or
threatening of any Proceeding for such purpose and (v) of the occurrence of any event or passage of time that makes the financial statements included in a Registration Statement ineligible for inclusion therein or any statement made in such
Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to such Registration Statement, Prospectus or other documents so that,
in the case of such Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements
therein (in the case of any Prospectus, form of prospectus or supplement thereto, in light of the circumstances under which they were made), not misleading. 
 (d) Use commercially reasonable efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of a Registration Statement, or (ii) any
suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, as soon as practicable. 
 (e) If requested by a Holder, furnish to such Holder, without charge, at least one conformed copy of each Registration Statement and each amendment thereto and all exhibits to the extent requested by such
Person (including those previously furnished or incorporated by reference) promptly after the filing of such documents with the Commission; provided, that the Company shall have no obligation to provide any document pursuant to this clause
that is available on the Commission’s EDGAR system. 
 (f) Prior to any resale of Registrable Securities by a Holder, use
its commercially reasonable efforts to register or qualify or cooperate with the selling Holders in connection with the registration or qualification (or exemption from the registration or qualification) of such Registrable Securities for the resale
by the Holder under the securities or Blue Sky laws of such jurisdictions within the United States as any Holder reasonably requests in writing, to keep each registration or qualification (or exemption therefrom) effective during the Effectiveness
Period and to do any and all other acts or things reasonably necessary to enable the disposition in such jurisdictions of the Registrable Securities covered by each Registration Statement; provided, that the Company shall not be required to
qualify generally to do business in any jurisdiction where it is not then so qualified, subject the Company to any material tax in any such jurisdiction where it is not then so subject or file a general consent to service of process in any such
jurisdiction. 
 (g) If requested by a Holder, cooperate with such Holder to facilitate the timely preparation and delivery of
certificates representing Registrable Securities to be delivered to a transferee pursuant to the Registration Statement, which certificates shall be free, to the extent permitted by the Purchase Agreement and under law, of all restrictive legends,
and to enable such Registrable Securities to be in such denominations and registered in such names as any such Holders may reasonably request. 
 (h) Following the occurrence of any event contemplated by Section 3(c), as promptly as reasonably practicable (taking into account the Company’s good faith assessment of any adverse consequences
to the Company and its stockholders of the premature disclosure of such event), prepare a supplement or amendment, including a post-effective amendment, to the affected Registration Statements or a supplement to the related Prospectus or any
document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, no Registration Statement nor any Prospectus will contain an untrue statement of a material fact or omit
to state a material 

  
 9 

 
fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus, form of prospectus or supplement thereto, in light of the circumstances under which
they were made), not misleading. If the Company notifies the Holders in accordance with clauses (iii) through (v) of Section 3(c) above to suspend the use of any Prospectus until the requisite changes to such Prospectus have been
made, then the Holders shall suspend use of such Prospectus. The Company will use its commercially reasonable efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable. The Company shall be entitled to exercise
its right under this Section 3(h) to suspend the availability of a Registration Statement and Prospectus for a period not to exceed 45 calendar days (which need not be consecutive days) in any 12-month period without incurring liability for
Liquidated Damages otherwise required pursuant to Section 2(c). For the avoidance of doubt, any period of time for which the availability of a Registration Statement and Prospectus are suspended pursuant to Sections 2(e) and (f) shall be
disregarded when determining the time period allotted under this Section 3(h). 
 (i) The Company may require each selling
Holder to furnish to the Company a certified statement as to (i) the number of shares of Common Stock beneficially owned by such Holder and any Affiliate thereof, (ii) any Financial Industry Regulatory Authority, Inc.
(“FINRA”) affiliations, (iii) any natural persons who have the power to vote or dispose of the common stock and (iv) any other information as may be requested by the Commission, FINRA or any state securities commission.
During any periods that the Company is unable to meet its obligations hereunder with respect to the registration of Registrable Securities because any Holder fails to furnish such information within three Trading Days of the Company’s request,
any Liquidated Damages that are accruing at such time as to such Holder only shall be tolled and any Event that may otherwise occur solely because of such delay shall be suspended as to such Holder only, until such information is delivered to the
Company. 
 (j) The Company shall cooperate with any registered broker through which a Holder proposes to resell its Registrable
Securities in effecting a filing with FINRA pursuant to FINRA Rule 5110 as reasonably requested by any such Holder, and the Company shall pay the filing fee required for the first such filing within five Business Days of the request therefor.

 4. Registration Expenses. All fees and expenses incident to the Company’s performance of or compliance with its
obligations under this Agreement (excluding any underwriting discounts and selling commissions and all legal fees and expenses of legal counsel for any Holder) shall be borne by the Company whether or not any Registrable Securities are sold pursuant
to a Registration Statement. The fees and expenses referred to in the foregoing sentence shall include, without limitation, (i) all registration and filing fees (including, without limitation, fees and expenses (A) with respect to filings
required to be made with any Trading Market on which the Common Stock is then listed for trading, (B) with respect to compliance with applicable state securities or Blue Sky laws (including, without limitation, fees and disbursements of counsel
for the Company in connection with Blue Sky qualifications or exemptions of the Registrable Securities and determination of the eligibility of the Registrable Securities for investment under the laws of such jurisdictions as requested by the
Holders) and (C) if not previously paid by the Company pursuant to Section 3(j) hereof, with respect to any filing that may be required to be made by any broker through which a Holder intends to make sales of Registrable Securities with
FINRA pursuant to FINRA Rule 5110, so long as the broker is receiving no more than a customary brokerage commission in connection with such sale, (ii) printing expenses (including, without limitation, expenses of printing certificates for
Registrable Securities and of printing prospectuses if the printing of prospectuses is reasonably requested by the Holders of a majority of the Registrable Securities included in the Registration Statement), (iii) messenger, telephone and
delivery expenses, (iv) fees and disbursements of counsel for the Company, (v) Securities Act liability insurance, if the Company so desires such insurance, and (vi) fees and expenses of all other Persons retained by the Company in
connection with the consummation of the transactions contemplated by this Agreement. In addition, the Company shall be 

  
 10 

 
responsible for all of its internal expenses incurred in connection with the consummation of the transactions contemplated by this Agreement (including, without limitation, all salaries and
expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit and the fees and expenses incurred in connection with the listing of the Registrable Securities on any securities exchange as required
hereunder. In no event shall the Company be responsible for any underwriting, broker or similar fees or commissions of any Holder or, except to the extent provided for in the Transaction Documents, any legal fees or other costs of the Holders.

 5. Indemnification. 
 (a) Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify, defend and hold harmless each Holder, the officers, directors, agents, partners,
members, managers, stockholders, Affiliates and employees of each of them, each Person who controls any such Holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors,
partners, members, managers, stockholders, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without
limitation, reasonable costs of preparation and investigation and reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon (i) any untrue or alleged untrue
statement of a material fact contained in any Registration Statement, any Prospectus or any form of prospectus or in any amendment or supplement thereto (it being understood that the Holder has approved Annex A hereto for this purpose) or in any
preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or
supplement thereto, in light of the circumstances under which they were made) not misleading or (ii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act or any state securities law, or any rule or
regulation thereunder relating to the offer or sale of the Registrable Securities pursuant to the Registration Statement or any violation of this Agreement, except to the extent, but only to the extent that (A) such untrue statements, alleged
untrue statements, omissions or alleged omissions are based solely upon information regarding such Holder furnished in writing to the Company by such Holder expressly for use therein, or to the extent that such information relates to such Holder or
such Holder’s proposed method of distribution of Registrable Securities and was reviewed and approved in writing by such Holder expressly for use in the Registration Statement, such Prospectus or such form of Prospectus or in any amendment or
supplement thereto (it being understood that each Holder has approved Annex A hereto for this purpose) or (B) in the case of an occurrence of an event of the type specified in Section 3(c)(iii)-(v), related to the use by a Holder of
an outdated or defective Prospectus after the Company has notified such Holder in writing that the Prospectus is outdated or defective and prior to the receipt by such Holder of the Advice contemplated and defined in Section 6(d) below,
following the receipt of the Advice the misstatement or omission giving rise to such Loss would have been corrected, or (C) any such Losses arise out of the Purchaser’s (or any other indemnified Person’s) failure to send or give a
copy of the Prospectus or supplement (as then amended or supplemented), if required pursuant to Rule 172 under the Securities Act (or any successor rule), to the Persons asserting an untrue statement or alleged untrue statement or alleged untrue
statement or omission or alleged omission at or prior to the written confirmation of the sale of Registrable Securities to such Person if such statement or omission was corrected in such Prospectus or supplement. The Company shall notify the Holders
promptly of the institution, threat or assertion of any Proceeding arising from or in connection with the transactions contemplated by this Agreement of which the Company is aware. Such indemnity shall remain in full force and effect regardless of
any investigation made by or on behalf of an Indemnified Party (as defined in Section 5(c)) and shall survive the transfer of the Registrable Securities by the Holders. 

  
 11 

 (b) Indemnification by Holders. Each Holder shall, severally and not jointly,
indemnify and hold harmless the Company, its directors, officers, agents, stockholders, Affiliates and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange
Act), and the directors, officers, agents or employees of such controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of or are based solely upon any untrue or alleged untrue
statement of a material fact contained in any Registration Statement, any Prospectus, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged
omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not
misleading (i) to the extent, but only to the extent, that such untrue statements or omissions are based upon information regarding such Holder furnished in writing to the Company by such Holder expressly for use therein or (ii) to the
extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and approved in writing by such Holder expressly for use in a Registration Statement (it being
understood that the Holder has approved Annex A hereto for this purpose), such Prospectus or such form of Prospectus or in any amendment or supplement thereto or (iii) in the case of an occurrence of an event of the type specified in
Section 3(c)(iii)-(v), to the extent, but only to the extent, related to the use by such Holder of an outdated or defective Prospectus after the Company has notified such Holder in writing that the Prospectus is outdated or defective and prior
to the receipt by such Holder of the Advice contemplated in Section 6(d). In no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the net proceeds received by such Holder upon the sale of
the Registrable Securities giving rise to such indemnification obligation. 
 (c) Conduct of Indemnification Proceedings.
If any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the
“Indemnifying Party”) in writing, and the Indemnifying Party shall have the right to assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all reasonable
fees and expenses incurred in connection with defense thereof, provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement,
except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have materially and adversely prejudiced the
Indemnifying Party. 
 An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to
participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such fees and expenses; (2) the
Indemnifying Party shall have failed promptly to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3) the named parties to any such Proceeding (including
any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that a conflict of interest exists if the same counsel were to represent such Indemnified Party and
the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume
the defense thereof and such counsel shall be at the expense of the Indemnifying Party); provided, that the Indemnifying Party shall not be liable for the fees and expenses of more than one separate firm of attorneys at any time for all
Indemnified Parties. The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its prior written consent, which consent shall not be unreasonably withheld, delayed or conditioned. No Indemnifying Party
shall, without the prior written consent of the Indemnified Party, 

  
 12 

 
effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from all
liability on claims that are the subject matter of such Proceeding and such settlement does not include any non-monetary limitation on the actions of any Indemnified Party or any of its affiliates or any admission of fault or liability on behalf of
any such Indemnified Party. 
 Subject to the terms of this Agreement, all fees and expenses of the Indemnified Party (including
reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section 5) shall be paid to the Indemnified Party, as incurred, within 20 Trading
Days of written notice thereof to the Indemnifying Party; provided, that the Indemnified Party shall promptly reimburse the Indemnifying Party for that portion of such fees and expenses applicable to such actions for which such Indemnified
Party is finally judicially determined to not be entitled to indemnification hereunder). The failure to deliver written notice to the Indemnifying Party within a reasonable time of the commencement of any such action shall not relieve such
Indemnifying Party of any liability to the Indemnified Party under this Section 5, except to the extent that the Indemnifying Party is materially and adversely prejudiced in its ability to defend such action. 

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

The indemnity and contribution agreements contained in this Section 5 are in addition to any liability that the Indemnifying Parties
may have to the Indemnified Parties and are not in diminution or limitation of the indemnification provisions under the Purchase Agreement. 

  
 13 

 6. Miscellaneous. 

(a) Remedies. Subject to the limitations set forth elsewhere in this Agreement, in the event of a breach by the Company or by a
Holder of any of their obligations under this Agreement, each Holder or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to
specific performance of its rights under this Agreement. The Company and each Holder agree that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it of any of the provisions of this Agreement
and hereby further agrees that, in the event of any action for specific performance in respect of such breach, it shall waive the defense that a remedy at law would be adequate. 

(b) No Piggyback on Registrations; Prohibition on Filing Other Registration Statements. Neither the Company nor any of its
security holders (other than the Holders in such capacity pursuant hereto) may include securities of the Company in a Registration Statement other than the Registrable Securities and the Company shall not prior to the initial Effective Date of the
Initial Registration Statement enter into any new agreement providing any such right to any of its security holders. The Company shall not file with the Commission a registration statement relating to an offering for its own account under the
Securities Act of any of its equity securities other than a Special Registration Statement until the earlier of (i) the date that the Initial Registration Statement or New Registration Statement, as the case may be, is declared effective or
(ii) the date that all Registrable Securities are eligible for resale by non-affiliates without volume or manner of sale restrictions under Rule 144 and without the requirement for the Company to be in compliance with the current public
information requirements under Rule 144. For the avoidance of doubt, the Company shall not be prohibited from preparing and filing with the Commission a registration statement relating to an offering of Common Stock by existing stockholders of the
Company under the Securities Act pursuant to the terms of registration rights held by such stockholder or from filing amendments to registration statements filed prior to the date of this Agreement. 

(c) Compliance. Each Holder covenants and agrees that it will comply with the prospectus delivery requirements of the Securities
Act as applicable to it (unless an exemption therefrom is available) in connection with sales of Registrable Securities pursuant to the Registration Statement and shall sell the Registrable Securities only in accordance with a method of distribution
described in the Registration Statement 
 (d) Discontinued Disposition. By its acquisition of Registrable Securities,
the Holder agrees that, upon receipt of a notice from the Company of the occurrence of any event of the kind described in Section 3(c)(iii)-(v), such Holder will forthwith discontinue disposition of such Registrable Securities under a
Registration Statement until it is advised in writing (the “Advice”) by the Company that the use of the applicable Prospectus (as it may have been supplemented or amended) may be resumed. The Company will use its commercially
reasonable efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable. The Company may provide appropriate stop orders to enforce the provisions of this paragraph. 

(e) Piggy-Back Registrations. If, at any time during the Effectiveness Period, there is not an effective Registration Statement
covering all of the Registrable Securities and the Company shall determine to prepare and file with the Commission a registration statement relating to an offering for its own account or the account of others under the Securities Act of any of its
equity securities, other than on a Special Registration Statement, then the Company shall deliver to each Holder a written notice of such determination and, if within seven days after the date of the delivery of such notice, any such Holder shall so
request in writing, the Company shall include in such registration statement all or any part of such Registrable Securities such Holder requests to be registered; provided, however, that the Company shall

  
 14 

 
not be required to register any Registrable Securities pursuant to this Section 6(e) that are (i) eligible for resale pursuant to Rule 144 without the requirement for the Company to be
in compliance with the current public information required thereunder and without volume or manner-of-sale restrictions or (ii) the subject of a then-effective Registration Statement. 

(f) No Inconsistent Agreements. The Company has not entered, as of the date hereof, nor shall the Company, on or after the date
hereof, enter into any agreement with respect to its securities, that would have the effect of impairing the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. 

(g) Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended,
modified or supplemented, or waived unless the same shall be in writing and signed by the Company and Holders holding no less than 66 2/3% of the then outstanding Registrable Securities, in which case such amendment, modification, supplement or
waiver shall be binding on all Holders, provided that any party may give a waiver as to itself. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights
of Holders and that does not directly or indirectly affect the rights of other Holders may be given by Holders of all of the Registrable Securities to which such waiver or consent relates; provided, however, that the provisions of this
sentence may not be amended, modified, or supplemented except in accordance with the provisions of the immediately preceding sentence. 
 (h) Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be delivered as set forth in the Purchase Agreement. 

(i) Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and permitted assigns
of each of the parties and shall inure to the benefit of each Holder. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights, remedies,
obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. The Company may not assign its rights (except by merger or in connection with another entity acquiring all or substantially all of the
Company’s assets) or obligations hereunder without the prior written consent of all the Holders of the then outstanding Registrable Securities. Each Holder may assign its respective rights with respect to any or all of its Shares and/or Warrant
Shares hereunder in the manner and to the Persons as permitted under the Purchase Agreement; provided in each case that (i) the Holder agrees in writing with the transferee or assignee to assign such rights and related obligations under
this Agreement, and for the transferee or assignee to assume such obligations, and a copy of such agreement is furnished to the Company within a reasonable time after such assignment, (ii) the Company is, within a reasonable time after such
transfer or assignment, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being transferred or assigned, (iii) at or before the time the
Company received the written notice contemplated by clause (ii) of this sentence, the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained herein and (iv) the transferee is an
“accredited investor,” as that term is defined in Rule 501 of Regulation D. 
 (j) Execution and
Counterparts. This Agreement may be executed in two or more counterparts, each of which when so executed shall be deemed to be an original and, all of which taken together shall constitute one and the same Agreement and shall become effective
when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery
of a “.pdf” format data file, such signature shall create a valid and binding obligation of the 

  
 15 

 
party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature were the original thereof. 

(k) Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be
determined in accordance with the provisions of the Purchase Agreement. 
 (l) Cumulative Remedies. Except as provided
herein, the remedies provided herein are cumulative and not exclusive of any other remedies provided by law. 
 (m)
Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set
forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their good faith reasonable efforts to find and employ an alternative means to achieve the same or
substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and
restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable. 
 (n)
Headings. The headings in this Agreement are for convenience only and shall not limit or otherwise affect the meaning hereof. 
 (o) Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under this Agreement are several and not joint with the obligations of any other Purchaser
hereunder, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser hereunder. The decision of each Purchaser to purchase the Securities pursuant to the Transaction Documents has been made
independently of any other Purchaser. Nothing contained herein or in any other agreement or document delivered at any closing, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the Purchasers as a
partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert with respect to such obligations or the transactions contemplated by this Agreement. Each
Purchaser acknowledges that no other Purchaser has acted as agent for such Purchaser in connection with making its investment hereunder and that no Purchaser will be acting as agent of such Purchaser in connection with monitoring its investment in
the Securities or enforcing its rights under the Transaction Documents. Each Purchaser shall be entitled to protect and enforce its rights, including, without limitation, the rights arising out of this Agreement, and it shall not be necessary for
any other Purchaser to be joined as an additional party in any Proceeding for such purpose. The Company acknowledges that each of the Purchasers has been provided with the same Registration Rights Agreement for the purpose of closing a transaction
with multiple Purchasers and not because it was required or requested to do so by any Purchaser.

 Annex A 
 PLAN OF DISTRIBUTION 
 We are registering the shares of common stock
previously issued to the selling stockholders and issuable upon exercise of the warrants previously issued to the selling stockholders to permit the resale of these shares of common stock by the holders of the common stock and warrants from time to
time after the date of this prospectus. We will not receive any of the proceeds from the sale by the selling stockholders of the shares of common stock. We will bear all fees and expenses incident to our obligation to register the shares of common
stock. 
 The selling stockholders may sell all or a portion of the shares of common stock beneficially owned by them and
offered hereby from time to time directly or through one or more underwriters, broker-dealers or agents. If the shares of common stock are sold through underwriters or broker-dealers, the selling stockholders will be responsible for underwriting
discounts or commissions or agent’s commissions. The shares of common stock may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at
negotiated prices. The selling stockholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. These sales may be effected in transactions, which may involve crosses or block transactions,

  

	 	•	 	 on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale;

  

	 	•	 	 in the over-the-counter market; 

  

	 	•	 	 in transactions otherwise than on these exchanges or systems or in the over-the-counter market; 

 

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

 

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

 

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

  

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

 

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

 

	 	•	 	 privately negotiated transactions; 

  

	 	•	 	 short sales; 

  

	 	•	 	 through the distribution of the common stock by any selling stockholders to its partners, members or stockholders; 

	 	•	 	 through one or more underwritten offerings on a firm commitment or best efforts basis; 

 

	 	•	 	 sales pursuant to Rule 144; 

  

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

  

	 	•	 	 a combination of any such methods of sale; and 

  

	 	•	 	 any other method permitted pursuant to applicable law. 

 If the selling stockholders effect such transactions by selling shares of common stock to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive
commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from purchasers of the shares of common stock for whom they may act as agent or to whom they may sell as principal (which discounts,
concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the shares of common stock or otherwise, the selling
stockholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares of common stock in the course of hedging in positions they assume. The selling stockholders may also sell shares of common
stock short and deliver shares of common stock covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The selling stockholders may also loan or pledge shares of common stock to
broker-dealers that in turn may sell such shares. 
 The selling stockholders may pledge or grant a security interest in some or
all of the shares of common stock or warrants owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time to time pursuant to this
prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending, if necessary, the list of selling stockholders to include the pledgee, transferee or other successors in interest as
selling stockholders under this prospectus. The selling stockholders also may transfer and donate the shares of common stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling
beneficial owners for purposes of this prospectus. 
 The selling stockholders and any broker-dealer participating in the
distribution of the shares of common stock may be deemed to be “underwriters” within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be
underwriting commissions or discounts under the Securities Act. At the time a particular offering of the shares of common stock is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of shares of
common stock being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling stockholders and any discounts, commissions
or concessions allowed or reallowed or paid to broker-dealers. The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares of common stock against certain liabilities, including
liabilities arising under the Securities Act. 

 Under the securities laws of some states, the shares of common stock may be sold in such
states only through registered or licensed brokers or dealers. In addition, in some states the shares of common stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or
qualification is available and is complied with. 
 There can be no assurance that any selling stockholder will sell any or all
of the shares of common stock registered pursuant to the registration statement, of which this prospectus forms a part. 
 The
selling stockholders and any other person participating in such distribution will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act,
which may limit the timing of purchases and sales of any of the shares of common stock by the selling stockholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the shares
of common stock to engage in market-making activities with respect to the shares of common stock. All of the foregoing may affect the marketability of the shares of common stock and the ability of any person or entity to engage in market-making
activities with respect to the shares of common stock. 
 We will pay all expenses of the registration of the shares of common
stock pursuant to the registration rights agreement, estimated to be $              in total, including, without limitation, SEC filing fees and expenses of compliance with state
securities or “Blue Sky” laws; provided, however, that a selling stockholder will pay all underwriting discounts and selling commissions, if any. We will indemnify the selling stockholders against liabilities, including some
liabilities under the Securities Act, in accordance with the registration rights agreement, or the selling stockholders will be entitled to contribution. We may be indemnified by the selling stockholders against civil liabilities, including
liabilities under the Securities Act, that may arise from any written information furnished to us by the selling stockholder specifically for use in this prospectus, in accordance with the registration rights agreement, or we may be entitled to
contribution. 
 Once sold under the registration statement, of which this prospectus forms a part, the shares of common stock
will be freely tradable in the hands of persons other than our affiliates.

compliance with all applicable federal and state securities laws. As of the Closing Date, the Company shall have reserved from its duly authorized capital stock the number of shares of Common
Stock issuable upon exercise of the Warrants (without taking into account any limitations on the exercise of the Warrants set forth in the Warrants). The Company shall, so long as any of the Warrants are outstanding, take all action necessary to
reserve and keep available out of its authorized and unissued capital stock, solely for the purpose of effecting the exercise of the Warrants, the number of shares of Common Stock issuable upon exercise of the Warrants (without taking into account
any limitations on the exercise of the Warrants set forth in the Warrants). 
 (g) Capitalization. The capitalization of
the Company is as described in its most recently filed SEC Report on Form 10-K, except for issuances pursuant to this Agreement, stock option exercises, issuances pursuant to equity incentive plans or exercises of warrants. The Company has not
issued any capital stock since the date of its most recently filed SEC Report other than to reflect stock option and warrant exercises that do not, individually or in the aggregate, have a material affect on the issued and outstanding capital stock,
options and other securities of the Company. No Person has any right of first refusal, preemptive right, right of participation, or any similar right to participate in the transactions contemplated by the Transaction Documents that have not been
effectively waived as of the Closing Date. Except as set forth on Schedule 3.1(g) or a result of the purchase and sale of the Shares and Warrants, there are no outstanding options, warrants, scrip rights to subscribe to, calls or commitments of
any character whatsoever relating to, or securities, rights or obligations convertible into or exercisable or exchangeable for, or giving any Person any right to subscribe for or acquire any shares of Common Stock, or contracts, commitments,
understandings or arrangements by which the Company or any Subsidiary is or may become bound to issue additional shares of Common Stock or Common Stock Equivalents. The issuance and sale of the Shares and Warrants will not obligate the Company to
issue shares of Common Stock or other securities to any Person (other than the Purchasers) and will not result in a right of any holder of Company securities to adjust the exercise, conversion, exchange or reset price under any of such securities.
All of the outstanding shares of capital stock of the Company are validly issued, fully paid and nonassessable, have been issued in compliance in all material respects with all applicable federal and state securities laws, and none of such
outstanding shares was issued in violation of any preemptive rights or similar rights to subscribe for or purchase securities which violation would have or would reasonably be expected to result in a Material Adverse Effect. No further approval or
authorization of any stockholder, the Board of Directors or others is required for the issuance and sale of the Securities. There are no stockholders agreements, voting agreements or other similar agreements with respect to the Company’s
capital stock to which the Company is a party or, to the Company’s Knowledge, between or among any of the Company’s stockholders. 
 (h) SEC Reports; Disclosure Materials. The Company has filed all reports, schedules, forms, statements and other documents required to be filed by it under the Exchange Act, including pursuant to
Section 13(a) or 15(d) thereof, for the 12 months preceding the date hereof (or such shorter period as the Company was required by law or regulation to file such material) (the foregoing materials, including the exhibits thereto and documents
incorporated by reference therein, being collectively referred to herein as the “SEC Reports”, and the SEC Reports, together with the Disclosure Schedules, being collectively referred to as the “Disclosure
Materials”) 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, except where the failure to file on a timely basis would not have or
reasonably be expected to result in a Material Adverse Effect and would not have or 

  
 12 

 
reasonably be expected to result in any limitation or prohibition on the Company’s ability to register the Shares and Warrant Shares for resale on Form S-1 or any Purchaser’s ability to
use Rule 144 to resell any Securities. As of their respective filing dates, or to the extent corrected by a subsequent amendment, the SEC Reports complied in all material respects with the requirements of the Securities Act and the Exchange Act
and the rules and regulations of the Commission promulgated thereunder, and none of the 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 light of the circumstances under which they were made, not misleading. The Company has never been an issuer subject to Rule 144(i) under the Securities Act. Each of the Material Contracts to which the Company
or any Subsidiary is a party or to which the property or assets of the Company or any of its Subsidiaries are subject has been filed (or incorporated by reference) as an exhibit to the SEC Reports. 

(i) Financial Statements. The consolidated financial statements of the Company included in the SEC Reports comply in all material
respects with applicable accounting requirements and the rules and regulations of the Commission with respect thereto as in effect at the time of filing (or to the extent corrected by a subsequent amendment). Such consolidated financial statements
have been prepared in accordance with GAAP applied on a consistent basis during the periods involved, except as may be otherwise specified in such financial statements or the notes thereto and except that unaudited financial statements may not
contain all footnotes required by GAAP, and fairly present in all material respects the financial position of the Company and its consolidated subsidiaries taken as a whole as of and for the dates thereof and the results of operations and cash flows
for the periods then ended, subject, in the case of unaudited statements, to normal, immaterial year-end audit adjustments. 

(j) Material Changes. Since the date of the latest financial statements included within the SEC Reports, except as specifically
disclosed in a subsequent SEC Report filed prior to the date hereof and except as disclosed in Schedule 3.1(j), (i) there have been no events, occurrences or developments that have had or would reasonably be expected to have, either
individually or in the aggregate, a Material Adverse Effect, (ii) the Company has not incurred any material liabilities (contingent or otherwise) other than (A) trade payables and accrued expenses incurred in the ordinary course of
business consistent with past practice and (B) liabilities not required to be reflected in the Company’s financial statements pursuant to GAAP or required to be disclosed in filings made with the Commission, (iii) the Company has not
altered materially its method of accounting or the manner in which it keeps its accounting books and records, (iv) the Company has not declared or made any dividend or distribution of cash or other property to its stockholders or purchased,
redeemed or made any agreements to purchase or redeem any shares of its capital stock (other than in connection with repurchases of unvested stock issued to employees of the Company) and (v) the Company has not issued any equity securities to
any officer, director or Affiliate, except Common Stock issued in the ordinary course as dividends on outstanding preferred stock or issued pursuant to existing Company stock option or stock purchase plans or executive and director compensation
arrangements disclosed in the SEC Reports. Except as disclosed in Schedule 3.1(j) and except for the issuance of the Shares and Warrants contemplated by this Agreement, no event, liability or development has occurred or exists with respect to the
Company or its Subsidiaries or their respective business, properties, operations or financial condition, that would be required to be disclosed by the Company under applicable securities laws at the time this 

  
 13 

 
representation is made that has not been publicly disclosed at least one Trading Day prior to the date that this representation is made. 

(k) Litigation. There is no Action which (i) adversely affects or challenges the legality, validity or enforceability of any
of the Transaction Documents or the Securities or (ii) except as disclosed in Schedule 3.1(k), would, if there were an unfavorable decision, individually or in the aggregate, have or reasonably be expected to result in a Material Adverse
Effect. During the past five years, neither the Company nor any Subsidiary, nor to the Company’s Knowledge any director or officer thereof, is or has been the subject of any Action involving a claim of violation of or liability under federal or
state securities laws or a claim of breach of fiduciary duty. There has not been, and to the Company’s Knowledge there is not pending or contemplated, any investigation by the Commission involving the Company or any current or former director
or officer of the Company. During the past five years, the Commission has not issued any stop order or other order suspending the effectiveness of any registration statement filed by the Company under the Exchange Act or the Securities Act.

 (l) Employment Matters. No material labor dispute exists or, to the Company’s Knowledge, is imminent with respect
to any of the employees of the Company which would have or would reasonably be expected to result in a Material Adverse Effect. None of the Company’s or any Subsidiary’s employees is a member of a labor union that relates to such
employee’s relationship with the Company, and neither the Company nor any of its Subsidiaries is a party to a collective bargaining agreement. Except as disclosed in Schedule 3.1(l), no executive officer of the Company (as defined in Rule
501(f) of the Securities Act) has notified the Company or any of its Subsidiaries that such officer intends to leave the Company or any such Subsidiary or otherwise terminate such officer’s employment with the Company or any such Subsidiary. To
the Company’s Knowledge, no executive officer or key employee, is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement or non-competition
agreement, or any other contract or agreement or any restrictive covenant in favor of any third party, and to the Company’s Knowledge, the continued employment of each such executive officer or key employee does not subject the Company or any
Subsidiary to any liability with respect to any of the foregoing matters, except, in each case, matters that, individually or in the aggregate, would not reasonably be expected to result in a Material Adverse Effect. The Company is in compliance
with all U.S. federal, state, local and foreign laws and regulations relating to employment and employment practices, terms and conditions of employment and wages and hours, except where the failure to be in compliance would not, individually or in
the aggregate, reasonably be expected to result in a Material Adverse Effect. 
 (m) Compliance. Neither the Company nor
any of its Subsidiaries (i) is in default under or in violation of (and no event has occurred that has not been waived that, with notice or lapse of time or both, would result in a default by the Company or any of its Subsidiaries under), nor
has the Company or any of its Subsidiaries received written notice of a claim that it is in default under or that it is in violation of, any Material Contract (whether or not such default or violation has been waived), (ii) is in violation of
any order of any court, arbitrator or governmental body having jurisdiction over the Company or any of its Subsidiaries or their properties or assets, or (iii) is in violation of, or in receipt of written notice that it is in violation of, any
statute, rule or regulation of any governmental authority applicable to the Company or any of its Subsidiaries, except in each 

  
 14 

 
case as would not, individually or in the aggregate, have or reasonably be expected to result in a Material Adverse Effect. 

(n) Regulatory Permits. The Company and each of its Subsidiaries possesses all certificates, authorizations and permits issued by
the appropriate federal, state, local or foreign regulatory authorities necessary to conduct its business as currently conducted, except as set forth in the SEC Reports, or such that where the failure to possess such permits, individually or in the
aggregate, has not and would not have or would not reasonably be expected to result in a Material Adverse Effect (“Material Permits”), and neither the Company nor any of its Subsidiaries has received any notice of Proceedings
relating to the revocation or modification of any such Material Permits. 
 (o) Title to Assets. The Company and each of
its Subsidiaries has good and marketable title to all tangible personal property owned by it that is material to its business, in each case free and clear of all Liens except such as do not materially affect the value of such property and do not
interfere with the use made and proposed to be made of such property by the Company. Any real property and facilities held under lease by the Company and any of its Subsidiaries are held by it under valid, subsisting and enforceable leases with such
exceptions as are not material and do not interfere with the use made and proposed to be made of such property and buildings by the Company and its Subsidiaries. 
 (p) Patents and Trademarks. Except as disclosed in Schedule 3.1(p), to the Company’s Knowledge, the Company and each of its Subsidiaries owns, possesses, licenses or has other rights to use,
all patents, patent applications, trade and service marks, trade and service mark applications and registrations, trade names, trade secrets, inventions, copyrights, licenses, technology, know-how and other intellectual property rights and similar
rights necessary or material for use in connection with its businesses as described in the SEC Reports and which the failure to so have would have or reasonably be expected to result in a Material Adverse Effect (collectively, the
“Intellectual Property Rights”). Except as disclosed in Schedule 3.1(p), to the Company’s Knowledge, none of the Intellectual Property Rights used by the Company or any Subsidiary violates or infringes upon the patent,
trademark, copyright, trade secret or other proprietary rights of any Person. There is no pending or, to the Company’s Knowledge, threatened action, suit, proceeding or claim by any Person that the Company’s or any Subsidiary’s
business as now conducted infringes or otherwise violates any patent, trademark, copyright, trade secret or other proprietary rights of another. To the Company’s Knowledge, there is no existing infringement by another Person of any of the
Intellectual Property Rights that would have or would reasonably be expected to result in a Material Adverse Effect. To the Company’s Knowledge, all patent applications and patents within the Intellectual Property Rights have been prosecuted
with a duty of candor, and, except as disclosed in Schedule 3.1(p), there is no material fact known by the Company that would preclude the issuance of patents with respect to said patent applications or that would render any issued patents invalid
or unenforceable. There is no pending or, to the Company’s Knowledge, threatened action, suit, proceeding or claim by another Person challenging the Company’s or any Subsidiary’s rights in or to any material Intellectual Property
Rights, or challenging inventorship, validity or scope of any such Intellectual Property Rights. The Company has taken reasonable security measures to protect the secrecy, confidentiality and value of all of its and its Subsidiaries’
Intellectual Property Rights, except where failure to do so would not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect. None 

  
 15 

 
of the technology employed by the Company or any of its Subsidiaries has been obtained or is being used by the Company or any Subsidiary in violation of any contractual obligation binding on the
Company or any Subsidiary or, to the Company’s Knowledge, any of its or its Subsidiaries’ officers, directors or employees or otherwise in violation of the rights of any Person, which violations would have or would reasonably be expected
to have a Material Adverse Effect. 
 (q) Insurance. The Company and each of its Subsidiaries is insured by insurers of
recognized financial responsibility against such losses and risks and in such amounts as the Company believes to be prudent and customary in the businesses and locations in which the Company and the Subsidiaries are engaged. None of the Company or
any of its Subsidiaries has received any written notice of cancellation of any such insurance, nor, to the Company’s Knowledge, will it or any Subsidiary be unable to renew its existing insurance coverage as and when such coverage expires or to
obtain similar coverage from similar insurers as may be necessary to continue its business without a material increase in cost. 

(r) Transactions With Affiliates and Employees. Except as set forth in the SEC Reports, none of the executive officers or
directors of the Company and, to the Company’s Knowledge, none of the employees of the Company is presently a party to any transaction with the Company (other than for services as employees, officers and directors) that would be required to be
disclosed pursuant to Item 404 of Regulation S-K promulgated under the Securities Act. 
 (s) Internal Accounting
Controls. The Company maintains a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations,
(ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset and liability accountability, (iii) access to assets or incurrence of liabilities is permitted only in
accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets and liabilities is compared with the existing assets and liabilities at reasonable intervals and appropriate action is taken
with respect to any differences. 
 (t) Sarbanes-Oxley; Disclosure Controls. The Company is in compliance in all material
respects with all of the provisions of the Sarbanes-Oxley Act of 2002 which are applicable to it. The Company has established disclosure controls and procedures (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) for the
Company and designed such disclosure controls and procedures to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the
time periods specified in the Commission’s rules and forms. The Company’s certifying officers have evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end of the period covered by the
Company’s most recently filed periodic report under the Exchange Act (such date, the “Evaluation Date”). The Company presented in its most recently filed periodic report under the Exchange Act the conclusions of the certifying
officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no changes in the Company’s internal control over financial reporting
(as such term is defined in the Exchange Act) that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

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

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

(w) Investment Company. The Company is not, and is not an Affiliate of, and immediately after receipt of payment for the Shares
and Warrants, will not be or be an Affiliate of, an “investment company” within the meaning of the Investment Company Act of 1940, as amended. The Company shall conduct its business in a manner so that it will not become subject to the
Investment Company Act of 1940, as amended. 
 (x) Registration Rights. Other than each of the Purchasers pursuant to the
Registration Rights Agreement, no Person has any right to cause the Company to effect the registration under the Securities Act of any securities of the Company. 
 (y) Listing and Maintenance Requirements. The Company’s Common Stock is registered pursuant to Section 12(b) or 12(g) of the Exchange Act, and the Company has taken no action designed to
terminate the registration of the Common Stock under the Exchange Act, nor has the Company received any notification that the Commission is contemplating terminating such registration. The Company has not, in the 12 months preceding the date hereof,
received written notice from any Trading Market on which the Common Stock is listed or quoted to the effect that the Company is not in compliance with the listing or maintenance requirements of such Trading Market. The Company is, and has no reason
to believe that it will not in the foreseeable future continue to be in compliance with all listing and maintenance requirements of the Principal Trading Market on the date hereof. 

(z) Application of Takeover Protections; Rights Agreements. The Company and the Board of Directors have taken all necessary
action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the Company’s charter
documents or the laws of its state of incorporation that is or could reasonably be expected to become applicable to any of the Purchasers as a result of the Purchasers and the Company fulfilling their obligations or 

  
 17 

 
exercising their rights under the Transaction Documents, including, without limitation, the Company’s issuance of the Securities and the Purchasers’ ownership of the Securities.

 (aa) Disclosure. Except as set forth on Schedule 3.1(aa), the Company confirms that it has not provided, and to the
Company’s Knowledge, none of its officers or directors nor any other Person acting on its or their behalf has provided, and it has not authorized the Placement Agent to provide, any Purchaser or its respective agents or counsel with any
information that it believes constitutes material, non-public information except insofar as the existence, provisions and terms of the Transaction Documents and the proposed transactions hereunder may constitute such information, all of which will
be disclosed by the Company in the Press Release as contemplated by Section 4.6 hereof. The Company understands and confirms that the Purchasers will rely on the foregoing representations in effecting transactions in securities of the Company.
All disclosure furnished by or on behalf of the Company to the Purchasers regarding the Company, its business and the transactions contemplated hereby, including the Disclosure Schedules to this Agreement, is true and correct and does not contain
any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading. The Company acknowledges and agrees that no
Purchaser makes or has made any representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in Section 3.2 hereto. 

(bb) No Integrated Offering. Assuming the accuracy of the Purchasers’ representations and warranties set forth in
Section 3.2, neither the Company nor, to the Company’s Knowledge, any Person acting on its behalf has, directly or indirectly, at any time within the past six months, made any offers or sales of any Company security or solicited any offers
to buy any security under circumstances that would (i) eliminate the availability of the exemption from registration under Regulation D under the Securities Act in connection with the offer and sale by the Company of the Securities as
contemplated hereby or (ii) cause the offering of the Securities pursuant to the Transaction Documents to be integrated with prior offerings by the Company for purposes of any applicable law, regulation or stockholder approval provisions,
including, without limitation, under the rules and regulations of any Trading Market on which any of the securities of the Company are listed or designated.

all other tax returns, reports and declarations required by any jurisdiction to which it is subject, (ii) has paid all taxes and other governmental assessments and charges that are material in amount, shown or determined to be due on such

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

(dd) Environmental Matters. To the Company’s Knowledge, none of the Company or any of its Subsidiaries (i) is in
violation of any statute, rule, regulation, decision or order of any governmental agency or body or any court, domestic or foreign, relating to the use,

(ee) No General Solicitation. Neither the Company nor, to the Company’s Knowledge, any person acting on behalf of the Company
has offered or sold any of the Securities by any form of general solicitation or general advertising. 
 (ff) Off Balance
Sheet Arrangements. There is no transaction, arrangement, or other relationship between the Company, any Subsidiary and an unconsolidated or other off balance sheet entity that is required to be disclosed by the Company in the SEC Reports and is
not so disclosed and would have or reasonably be expected to result in a Material Adverse Effect.

Acknowledgment Regarding Purchasers’ Purchase of Securities. The Company acknowledges and agrees that each of the Purchasers is acting solely in the capacity of an arm’s length purchaser with respect to the Transaction
Documents and the transactions contemplated hereby and thereby. The Company further acknowledges that no Purchaser is acting as a financial advisor or fiduciary of the Company (or in any similar capacity) with respect to the Transaction

understanding with any Purchaser with respect to the transactions contemplated by the Transaction Documents other than as specified in the Transaction Documents. 
 3.2 Representations and Warranties of the Purchasers. Each Purchaser hereby, for itself and for no other Purchaser, represents and warrants as of the date hereof and as of the Closing Date to the
Company and the Placement Agent as follows: 
 (a) Organization; Authority. Such Purchaser is an entity duly organized,
validly existing and in good standing under the laws of the jurisdiction of its organization with the requisite corporate, limited liability company or partnership power and authority to enter into and to consummate the transactions contemplated by
the applicable Transaction Documents and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of this Agreement by such Purchaser and performance by such Purchaser of the transactions contemplated by this
Agreement have been duly authorized by all necessary corporate or, if such Purchaser is not a corporation, such partnership, limited liability company or other applicable like action, on the part of such Purchaser. Each Transaction Document to which
it is a party has been duly executed by such Purchaser, and when delivered by such Purchaser in accordance with the terms hereof, will constitute the valid and legally binding obligation of such Purchaser, enforceable against it in accordance with
its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting generally the enforcement of, creditors’ rights and remedies or by
other equitable principles of general application. 
 (b) No Conflicts. The execution, delivery and performance by such
Purchaser of this Agreement and the Registration Rights Agreement and the consummation by such Purchaser of the transactions contemplated hereby and thereby will not (i) result in a violation of the organizational documents of such Purchaser,
(ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture
or instrument to which such Purchaser is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws) applicable to such Purchaser, except in the case of clauses
(ii) and (iii) above, for such conflicts, defaults, rights or violations which would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of such Purchaser to perform its
obligations hereunder. 
 (c) Investment Intent. Such Purchaser understands that the Securities are “restricted
securities” and have not been registered under the Securities Act or any applicable state securities law and is acquiring the Shares and Warrants and, upon exercise of the Warrants, will acquire the Warrant Shares issuable upon exercise thereof
as principal for its own account and not with a view to, or for distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable state securities laws, provided, however, that by making the

Commission involving the Company’s securities) acquiring, or obtaining the right to acquire, in excess of [4.999/9.999/14.999]% of the outstanding shares of Common Stock or the voting power of the Company on a post-transaction basis that
assumes that such Closing shall have occurred. Such Purchaser does not presently intend to, alone or together with others, make a public filing with the Commission to disclose that it has (or that it together with such other Persons have) acquired,
or obtained the right to acquire, as a result of such Closing (when added to any other securities of the Company that it or they then own or have the right to acquire), in excess of [4.999/9.999/14.999]% of the outstanding shares of Common Stock or
the voting power of the Company on a post-transaction basis that assumes the Closing shall have occurred.

 ARTICLE IV 
 OTHER AGREEMENTS OF THE PARTIES 
 4.1 Transfer Restrictions. 

(a) Compliance with Laws. Notwithstanding any other provision of this Article IV, each Purchaser, severally but not jointly,
covenants that the Securities may be disposed of only pursuant to an effective registration statement under, and in compliance with the requirements of, the Securities Act, or pursuant to an available exemption from, or in a transaction not subject
to, the registration requirements of the Securities Act, and in compliance with any applicable state and federal securities laws. In connection with any transfer of the Securities other than (i) pursuant to an effective registration statement,
(ii) to the Company, (iii) pursuant to Rule 144 (provided that such Purchaser provides the Company with reasonable assurances (in the form of seller and, if applicable, broker representation letters) that the securities may be sold
pursuant to such rule) or 

  
 24 

 
(iv) in connection with a bona fide pledge as contemplated in Section 4.1(b), the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the
transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities under the
Securities Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement and the Registration Rights Agreement and shall have the rights of a Purchaser under this Agreement and the
Registration Rights Agreement with respect to such transferred Securities. 
 (b) Legends. Certificates evidencing the
Securities shall bear any legend as required by the “blue sky” laws of any state and a restrictive legend in substantially the following form, until such time as they are not required under Section 4.1(c): 

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

The Company acknowledges and agrees that a Purchaser may from time to time pledge, and/or grant a security interest in, some or all of
the legended Securities in connection with applicable securities laws, pursuant to a bona fide margin agreement in compliance with a bona fide margin loan. Such a pledge would not be subject to approval or consent of the Company and no legal opinion
of legal counsel to the pledgee, secured party or pledgor shall be required in connection with the pledge, but such legal opinion shall be required in connection with a subsequent transfer or foreclosure following default by such Purchaser
transferee of the pledge. No notice shall be required of such pledge, but such Purchaser’s transferee shall promptly notify the Company of any such subsequent transfer or foreclosure of such legended Securities. Each Purchaser acknowledges that
the Company shall not be responsible for any pledges relating to, or the grant of any security interest in, any of the Securities or for any agreement, understanding or arrangement between any Purchaser and its pledgee or secured party. At the
appropriate Purchaser’s expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of Securities may reasonably request in connection with a pledge or transfer of the Securities, including the
preparation and filing of any required prospectus supplement under Rule 424(b)(3) of the Securities Act or other applicable provision of the Securities Act to appropriately amend the list 

  
 25 

 
of Selling Stockholders thereunder. Each Purchaser acknowledges and agrees that, except as otherwise provided in Section 4.1(c), any Securities subject to a pledge or security interest as
contemplated by this Section 4.1(b) shall continue to bear the legend set forth in this Section 4.1(b) and be subject to the restrictions on transfer set forth in Section 4.1(a). 

(c) Removal of Legends. The legend set forth in Section 4.1(b) above shall be removed and the Company shall issue a
certificate without such legend or any other legend to the holder of the applicable Securities upon which it is stamped or issue to such holder by electronic delivery at the applicable balance account at the Depository Trust Company
(“DTC”), if (i) such Securities are registered for resale under the Securities Act (provided that, if a Purchaser is selling pursuant to the Registration Statement, such Purchaser agrees to only sell such Securities during such
time that the Registration Statement is effective and not withdrawn or suspended, and only as permitted by the Registration Statement), (ii) such Securities are sold or transferred pursuant to Rule 144 (if the transferor is not an Affiliate of
the Company), or (iii) such Securities are eligible for sale under Rule 144, without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to such securities and without volume or
manner-of-sale restrictions. Following the earlier of (i) the Effective Date or (ii) Rule 144 becoming available for the resale of Securities, without the requirement for the Company to be in compliance with the current public information
required under Rule 144 as to such securities and without volume or manner-of-sale restrictions, the Company shall deliver to the Transfer Agent irrevocable instructions that the Transfer Agent shall reissue a certificate representing the applicable
Shares or issue a certificate representing the applicable Warrant Shares without legend upon receipt by the Transfer Agent of the legended certificates for such Shares. Any fees (with respect to the Transfer Agent or otherwise) associated with the
removal of such legend shall be borne by the Company. Following the Effective Date, or at such earlier time as a legend is no longer required for certain Securities (in which case a Purchase shall also be required to provide reasonable assurances
(in the form of seller and, if applicable, broker representation letters), the Company will no later than three Trading Days following the delivery by a Purchaser to the Company or the Transfer Agent (with notice to the Company) of (i) a
legended certificate representing Shares or Warrant Shares (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance and/or transfer) or (ii) an Exercise Notice and payment of the
applicable exercise price in the manner stated in the Warrants to effect the exercise of such Warrant in accordance with its terms, and an opinion of counsel to the extent required by Section 4.1(a) (such third Trading Day, the “Legend
Removal Date”), deliver or cause to be delivered to the transferee of such Purchaser or such Purchaser, as applicable, a certificate representing such Securities that is free from all restrictive and other legends. The Company may not make
any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 4.1(c) other than to comply with applicable law. Certificates for Shares or Warrant Shares subject to
legend removal hereunder may be transmitted by the Transfer Agent to a Purchaser by crediting the account of such Purchaser’s prime broker with DTC as directed by such Purchaser. 

(d) Irrevocable Transfer Agent Instructions. The Company shall issue irrevocable instructions to its transfer agent, and any
subsequent transfer agent, in substantially the form of Exhibit E attached hereto (the “Irrevocable Transfer Agent Instructions”). The Company represents and warrants that no instruction other than the Irrevocable Transfer Agent
Instructions referred to in this Section 4.1(d) (or instructions that are consistent therewith) will be given by the Company to its transfer agent in connection with this Agreement, and that the Securities shall 

  
 26 

 
otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement and the other Transaction Documents and applicable law. The Company
acknowledges that a breach by it of its obligations under this Section 4.1(d) will cause irreparable harm to a Purchaser. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this
Section 4.1(d) will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 4.1(d), that a Purchaser shall be entitled, in addition to all other available remedies, to an
order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required. 

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

(f) Buy-In. If the Company shall fail for any reason or for no reason to issue to a Purchaser unlegended certificates within three
Trading Days after receipt of all documents necessary for the removal of the legend set forth above (the “Deadline Date”), then, in addition to all other remedies available to such Purchaser, if on or after the Trading Day
immediately following such three Trading Day period, such Purchaser is required to purchase (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the holder of shares of Common Stock that such
Purchaser anticipated receiving from the Company without any restrictive legend (a “Buy-In”), then the Company shall, within three Trading Days after such Purchaser’s request and in the Company’s sole discretion, either
(i) pay cash to such Purchaser in an amount equal to such Purchaser’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the
shares of Common Stock held by such Purchaser equal to the number of shares of Common Stock so purchased shall be forfeited to the Company and the Company’s obligation to deliver such certificate (and to issue such shares of Common Stock) shall
terminate, or (ii) promptly honor its obligation to deliver to such Purchaser a certificate or certificates representing such shares of Common Stock and pay cash to the Purchaser in an amount equal to the excess (if any) of the Buy-In Price
over the product of (a) such number of shares of Common Stock, multiplied by (b) the 

  
 27 

 
Closing Bid Price on the Deadline Date. A Purchaser shall provide the Company written notice indicating the amounts payable to such Purchaser in respect of the Buy-In, together with applicable
confirmations and other evidence reasonably requested by the Company. 
 4.2 Reservation of Common Stock. The Company
shall take all action necessary to at all times during the period the Warrants are outstanding have authorized, and reserved for the purpose of issuance from and after the Closing Date, the number of shares of Common Stock issuable upon exercise of
the Warrants issued at the Closing (without taking into account any limitations on exercise of the Warrants set forth in the Warrants). 
 4.3 Acknowledgment of Dilution. The Company acknowledges that the issuance of the Shares may result in dilution of the outstanding shares of Common Stock, which dilution may be substantial under
certain market conditions. The Company further acknowledges that its obligations under the Transaction Documents, including without limitation its obligation to issue the Shares pursuant to the Transaction Documents, 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. 
 4.4 Furnishing of Information. In order to enable the Purchasers
to sell the Securities under Rule 144, until the earlier of (i) the date that the Securities cease to be Registrable Securities (as defined in the Registration Rights Agreement) (and for no less than 12 months from the Closing) or (ii) a
Fundamental Transaction (as defined in the Warrant) pursuant to which the Company is no longer a reporting company under the Exchange Act, the Company shall use its commercially reasonable efforts to timely file (or obtain extensions in respect
thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act. Except as set forth in clause (ii) above, during such period, if the Company is not
required to file reports pursuant to the Exchange Act, it will prepare and furnish to the Purchasers and make publicly available in accordance with Rule 144(c) such information as is required for the Purchasers to sell the Securities under Rule 144.

 4.5 No Integration. The Company shall not, and shall use its commercially reasonable efforts to ensure that no
Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that will be integrated with the offer or sale of the Securities in
a manner that would require the registration under the Securities Act of the sale of the Securities to the Purchasers, or that will be integrated with the offer or sale of the Securities for purposes of the rules and regulations of any Trading
Market such that it would require stockholder approval prior to the closing of such other transaction unless stockholder approval is obtained before the closing of such subsequent transaction. 

4.6 Securities Laws Disclosure; Publicity. By 9:00 a.m., New York City time, on the Trading Day immediately following the date
hereof, the Company shall issue a press release (the “Press Release”) reasonably acceptable to Piper Jaffray & Co. disclosing all material terms of the transactions contemplated hereby. On or before 5:30 p.m., New York City
time, on the fourth Trading Day immediately following the execution of this Agreement, the Company will file a Current Report on Form 8-K with the Commission describing the terms of the Transaction Documents (and including as exhibits to such
Current Report on Form 8-K the material Transaction Documents (including, without limitation, this Agreement, the form of Warrant and the Registration

Affiliate of any Purchaser in any press release or filing with the Commission (other than the Registration Statement) or any regulatory agency or Trading Market, without the prior written consent of such Purchaser, except (i) as required by
federal securities law in connection with (A) any registration statement contemplated by the Registration Rights Agreement and (B) the filing of final Transaction Documents (including signature pages thereto) with the Commission and
(ii) to the extent such disclosure is required by law, request of the Staff of the Commission or Trading Market regulations, in which case the Company shall provide the Purchasers with prior written notice of such disclosure permitted under
this subclause (ii). From and after the issuance of the Press Release, no Purchaser shall be in possession of any material, non-public information received from the Company or any of its officers, directors, employees or agents, that is not
disclosed in the Press Release unless a Purchaser shall have executed a written agreement regarding the confidentiality and use of such information. Each Purchaser, severally and not jointly with the other Purchasers, covenants that it will comply
with the provisions of any confidentiality or nondisclosure agreement executed by it and, in addition, until such time as the transactions contemplated by this Agreement are required to be publicly disclosed by the Company as described in this
Section 4.6, such Purchaser will maintain the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction). 

4.7 Shareholder Rights Plan. No claim will be made or enforced by the Company or, with the consent of the Company, any other
Person, that any Purchaser is an “Acquiring Person” under any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or similar anti-takeover plan or arrangement in effect or
hereafter adopted by the Company, or that any Purchaser could be deemed to trigger the provisions of any such plan or arrangement, in either case solely by virtue of receiving Securities under the Transaction Documents or under any other written
agreement between the Company and the Purchasers. 
 4.8 Non-Public Information. Except with respect to the material
terms and conditions of the transactions contemplated by the Transaction Documents, including this Agreement, or as expressly required by any applicable securities law, the Company covenants and agrees that neither it, nor any other Person acting on
its behalf, will provide any Purchaser or its agents or counsel with any information regarding the Company that the Company believes constitutes material non-public information without the express written consent of such Purchaser, unless prior
thereto such Purchaser shall have executed a written agreement regarding the confidentiality and use of such information. The Company understands and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions
in securities of the Company. 
 4.9 Use of Proceeds. The Company shall use the net proceeds from the sale of the Shares
and Warrants hereunder for working capital and general corporate purposes. 
 4.10 Indemnification of Purchasers. Subject
to the provisions of this Section 4.10, the Company will indemnify and hold each Purchaser and its directors, officers, shareholders, members, partners, employees and agents (and any other Persons with a functionally equivalent role of a Person
holding such titles notwithstanding a lack of such title or any other title), each Person who controls such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers,
shareholders, agents, members, partners or employees (and any other Persons with a functionally equivalent role of a Person holding such titles 

  
 29 

 
notwithstanding a lack of such title or any other title) of such controlling persons (each, a “Purchaser Party”) harmless from any and all losses, liabilities, obligations,
claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any such Purchaser Party may suffer or incur as a result of or
relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents or (ii) any action instituted against a Purchaser in any capacity, or
any Purchaser Party or their respective Affiliates, by any stockholder of the Company who is not an Affiliate of such Purchaser seeking indemnification, with respect to any of the transactions contemplated by the Transaction Documents (unless such
action is based upon a breach of such Purchaser’s representations, warranties or covenants under the Transaction Documents or any other agreement with the Company, or any agreements or understandings such Purchaser may have with any such
stockholder or any violations by the Purchaser of state or federal securities laws or any conduct by such Purchaser which constitutes fraud, gross negligence, willful misconduct or malfeasance). Promptly after receipt by any such Person (the
“Indemnified Person”) of notice of any demand, claim or circumstances which would or might give rise to a claim or the commencement of any action, proceeding or investigation in respect of which indemnity may be sought pursuant to
this Section 4.10, such Indemnified Person shall promptly notify the Company in writing and the Company shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Person, and shall assume
the payment of all fees and expenses relating to such action, proceeding or investigation; provided, however, that the failure of any Indemnified Person so to notify the Company shall not relieve the Company of its obligations hereunder except to
the extent that the Company is actually and materially prejudiced by such failure to notify. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the
expense of such Indemnified Person unless: (i) the Company and the Indemnified Person shall have mutually agreed to the retention of such counsel; (ii) the Company shall have failed promptly to assume the defense of such proceeding and to
employ counsel reasonably satisfactory to such Indemnified Person in such proceeding; or (iii) in the reasonable judgment of counsel to such Indemnified Person, representation of both parties by the same counsel would be inappropriate due to
actual or potential differing interests between them. The Company shall not be liable for any settlement of any proceeding effected without its prior written consent, which consent shall not be unreasonably withheld, delayed or conditioned. Without
the prior written consent of the Indemnified Person, which consent shall not be unreasonably withheld, delayed or conditioned, the Company shall not effect any settlement of any pending or threatened proceeding in respect of which any Indemnified
Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability arising out of such proceeding.

 4.11 Listing of Securities. In the time and manner required by the Principal Trading Market, the Company shall prepare
and file with such Principal Trading Market an additional shares listing application covering all of the Shares and Warrant Shares and shall use its reasonable best efforts to take all steps necessary to cause all of the Shares and Warrant Shares to
be approved for listing on the Principal Trading Market as promptly as possible thereafter. 
 4.12 Form D; Blue
Sky. The Company agrees to timely file a Form D with respect to the Securities as required under Regulation D and to provide a copy thereof, promptly upon the written 

  
 30 

 
request of any Purchaser. The Company, on or before the Closing Date, shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for or to
qualify the Securities for sale to the Purchasers at the Closing pursuant to this Agreement under applicable securities or “Blue Sky” laws of the states of the United States (or to obtain an exemption from such qualification) and shall
provide evidence of such actions promptly upon the written request of any Purchaser. 
 4.13 Delivery of Shares and Warrants
After Closing . The Company shall deliver, or cause to be delivered, the respective Shares and Warrants purchased by each Purchaser to such Purchaser within three Trading Days of the Closing Date. 

4.14 Dispositions and Confidentiality After The Date Hereof. Each Purchaser, severally and not jointly with the other Purchasers
shall not, and shall cause its Trading Affiliates not to, engage, directly or indirectly, in any transactions in the Company’s securities (including, without limitation, any Short Sales involving the Company’s securities) during the period
from the date hereof until the earlier of such time as (i) the transactions contemplated by this Agreement are first required to be publicly announced as described in Section 4.6 or (ii) this Agreement is terminated in full pursuant
to Section 6.16. Each Purchaser, severally and not jointly with the other Purchasers, covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company as described in Section 4.6, such
Purchaser will maintain the confidentiality of the existence and terms of this transaction and the information included in the Transaction Documents. Notwithstanding the foregoing, no Purchaser makes any representation, warranty or covenant hereby
that it will not engage in Short Sales in the securities of the Company after the time that the transactions contemplated by this Agreement are first publicly announced as described in Section 4.6; provided, however, each Purchaser agrees,
severally and not jointly with any Purchasers, that they will not enter into any Net Short Sales (as hereinafter defined) from the period commencing on the Closing Date and ending on the earliest of (x) the Effective Date of the initial
Registration Statement, (y) the 6 month anniversary of the Closing Date or (z) the date that such Purchaser no longer holds any Securities. For purposes of this Section 4.14, a “Net Short Sale” by any Purchaser shall mean a
sale of Common Stock by such Purchaser that is marked as a short sale and that is made at a time when there is no equivalent offsetting long position in Common Stock held by such Purchaser. For purposes of determining whether there is an equivalent
offsetting position in Common Stock held by the Purchaser, Warrant Shares that have not yet been issued pursuant to the exercise of Warrants shall be deemed to be held long by the Purchaser, and the amount of shares of Common Stock held in a long
position shall be all Shares and unexercised Warrant Shares (ignoring any exercise limitations included therein) issuable to such Purchaser on such date, plus any shares of Common Stock or Common Stock Equivalents otherwise then held by such
Purchaser. Notwithstanding the foregoing, in the event that a Purchaser is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct
knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s assets, the representation set forth above shall apply only with respect to the portion of assets managed by the portfolio manager
that have knowledge about the financing transaction contemplated by this Agreement. Moreover, notwithstanding the foregoing, in the event that a Purchaser has sold Securities pursuant to Rule 144 prior to the Effective Date of the initial
Registration Statement and the Company has failed to deliver certificates without legends prior to the settlement date for such sale (assuming that such certificates meet the requirements set forth in Section 4.1(c) for the

  
 31 

 
removal of legends), the provisions of this Section 4.14 shall not prohibit the Purchaser from entering into Net Short Sales for the purpose of delivering shares of Common Stock in
settlement of such sale. 
 4.15 Subsequent Equity Sales. From the date hereof until 30 days after the Effective Date of
the Initial Registration Statement (as defined in the Registration Rights Agreement), the Company shall not issue shares of Common Stock or Common Stock Equivalents; provided, however, the 30-day period set forth in this Section 4.15
shall be extended for the number of Trading Days during such period in which (i) trading in the Common Stock is suspended by any Trading Market within such 30-day period, or (ii) within 30 days of the Effective Date of the Initial
Registration Statement,, the Registration Statement is not effective or the prospectus included in the Registration Statement may not be used by the Purchasers for the resale of the Shares and Warrant Shares. Notwithstanding the foregoing, in no
event shall this Section 4.15 prohibit the Company from issuing shares of Common Stock or Common Stock Equivalents (i) in connection with acquisitions or strategic transactions approved by a majority of the disinterested directors of the
Company, provided that any such issuance shall only be to a Person which is, itself or through its subsidiaries, an operating company in a business synergistic with the business of the Company and in which the Company receives benefits in addition
to the investment of funds, but shall not include a transaction in which the Company is issuing securities primarily for the purpose of raising capital or to an entity whose primary business is investing in securities, (ii) upon the exercise of
any options or warrants outstanding on the date hereof, (iii) upon the exercise of the Warrants or (iv) to employees, directors or consultants pursuant to any stock option or equity incentive or employee stock purchase plan.

ARTICLE VI

amended except in a written instrument signed, in the case of an amendment, by the Company and the Purchasers holding or having the right to acquire 66 2/3% of the Shares and the Warrant Shares on a fully-diluted basis at the time of such amendment

Subscription Amount of any Purchaser, the Purchase Price or Section 2.1(a) of this Agreement or causes any such Purchaser to assume any additional liability or material obligation, may be effected only pursuant to a written instrument signed by
the Company and such Purchaser. 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 either party to exercise any right hereunder in any manner impair the exercise of any such right. No consideration shall be offered or paid to any Purchaser to amend or
consent to a waiver or modification of any 

  
 35 

 
provision of any Transaction Document unless the same consideration is also offered to all Purchasers who then hold Securities. 

6.5 Construction. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed
to limit or affect any of the provisions hereof. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party. This
Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement or any of the Transaction
Documents. 
 6.6 Successors and Assigns. The provisions of this Agreement shall inure to the benefit of and be binding
upon the parties and their successors and permitted assigns. This Agreement, or any rights or obligations hereunder, may not be assigned by the Company without the written consent of Purchasers holding or having the right to acquire 66 2/3% of the
Shares and the Warrant Shares on a fully-diluted basis at the time of such consent except to a successor in the event of a Fundamental Transaction. Any Purchaser may assign its rights hereunder in whole or in part to any Person to whom such
Purchaser assigns or transfers any Securities in compliance with the Transaction Documents and applicable law, provided that such transferee shall agree in writing to be bound, with respect to the transferred Securities, by the terms and conditions
of this Agreement that apply to the “Purchasers”. 
 6.7 No Third-Party Beneficiaries. This Agreement is
intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except (i) the Placement Agent is an intended
third party beneficiary of Article III hereof and (ii) each Purchaser Party is an intended third party beneficiary of Section 4.10. 
 6.8 Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by and construed and enforced in accordance with the
internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that all Proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement
and any other Transaction Documents (whether brought against a party hereto or its respective Affiliates, employees or agents) shall be commenced exclusively in the New York Courts. Each party hereto hereby irrevocably submits to the exclusive
jurisdiction of the New York Courts for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction
Documents), and hereby irrevocably waives, and agrees not to assert in any Proceeding, any claim that it is not personally subject to the jurisdiction of any such New York Court, or that such Proceeding has been commenced in an improper or
inconvenient forum. Each party hereto hereby irrevocably waives personal service of process and consents to process being served in any such Proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence
of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in
any way any right to serve process in any manner permitted by law. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN

  
 36 

 
ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. 
 6.9 Survival. Subject to applicable statute of limitations, the representations, warranties agreements and covenants contained herein shall survive the Closing and the delivery of the Securities.

 6.10 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be
considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any
signature is delivered by facsimile transmission, or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with
the same force and effect as if such facsimile signature page were an original thereof. 
 6.11 Severability. If any
provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will
attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement. 

6.12 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar
provisions of) the Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then
such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights. 

6.13 Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or
destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably
satisfactory to the Company and the Transfer Agent of such loss, theft or destruction and the execution by the holder thereof of a customary lost certificate affidavit of that fact and an agreement to indemnify and hold harmless the Company and the
Transfer Agent for any losses in connection therewith or, if required by the Transfer Agent, a bond in such form and amount as is required by the Transfer Agent. The applicants for a new certificate or instrument under such circumstances shall also
pay any reasonable third-party costs associated with the issuance of such replacement Securities. If a replacement certificate or instrument evidencing any Securities is requested due to a mutilation thereof, the Company may require delivery of such
mutilated certificate or instrument as a condition precedent to any issuance of a replacement. 
 6.14 Remedies. In
addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction Documents. The parties agree
that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of 

  
 37 

 
obligations described in the foregoing sentence and hereby agree to waive in any action for specific performance of any such obligation (other than in connection with any action for a temporary
restraining order) the defense that a remedy at law would be adequate. 
 6.15 Payment Set Aside. To the extent that the
Company makes a payment or payments to any Purchaser pursuant to any Transaction Document or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof
are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other person under any law
(including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and
continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred. 
 6.16
Adjustments in Share Numbers and Prices. In the event of any stock split, subdivision, dividend or distribution payable in shares of Common Stock (or other securities or rights convertible into, or entitling the holder thereof to receive
directly or indirectly shares of Common Stock), combination or other similar recapitalization or event occurring after the date hereof and prior to the Closing, each reference in any Transaction Document to a number of shares or a price per share
shall be deemed to be amended to appropriately account for such event. 
 6.17 Independent Nature of Purchasers’
Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the
obligations of any other Purchaser under any Transaction Document. The decision of each Purchaser to purchase Securities pursuant to the Transaction Documents has been made by such Purchaser independently of any other Purchaser and independently of
any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or any Subsidiary which may have been
made or given by any other Purchaser or by any agent or employee of any other Purchaser, and no Purchaser and any of its agents or employees shall have any liability to any other Purchaser (or any other Person) relating to or arising from any such
information, materials, statement or opinions. Nothing contained herein or in any Transaction Document, 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 Documents. Each Purchaser
acknowledges that no other Purchaser has acted as agent for such Purchaser in connection with making its investment hereunder and that no Purchaser will be acting as agent of such Purchaser in connection with monitoring its investment in the
Securities or enforcing its rights under the Transaction Documents. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement or out of the other
Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in its review and negotiation
of the Transaction Documents. For reasons of administrative convenience only, Purchasers and their respective counsels have chosen to communicate with the Company 

  
 38 

 
through Goodwin Procter LLP, counsel to the Placement Agent. Each Purchaser acknowledges that Goodwin Procter LLP has rendered legal advice to the Placement Agent and not to such Purchaser in
connection with the transactions contemplated hereby, and that each such Purchaser has relied for such matters on the advice of its own respective counsel. The Company has elected to provide all Purchasers with the same terms and Transaction
Documents for the convenience of the Company and not because it was required or requested to do so by any Purchaser. 
 6.18
Termination. This Agreement may be terminated and the sale and purchase of the Shares and the Warrants abandoned at any time prior to the Closing by either the Company or any Purchaser (with respect to itself only) upon written notice to the
other, if the Closing has not been consummated on or prior to 5:00 p.m., New York City time, on the Outside Date; provided, however, that the right to terminate this Agreement under this Section 6.18 shall not be available to any Person
whose failure to comply with its obligations under this Agreement has been the cause of or resulted in the failure of the Closing to occur on or before such time. Nothing in this Section 6.18 shall be deemed to release any party from any
liability for any breach by such party of the terms and provisions of this Agreement or the other Transaction Documents or to impair the right of any party to compel specific performance by any other party of its obligations under this Agreement or
the other Transaction Documents. In the event of a termination pursuant to this Section 6.18, the Company shall promptly notify all non-terminating Purchasers. Upon a termination in accordance with this Section 6.18, the Company and the
terminating Purchaser(s) shall not have any further obligation or liability (including arising from such termination) to the other, and no Purchaser will have any liability to any other Purchaser under the Transaction Documents as a result
therefrom. The Company and any Purchaser(s) may extend the term of this Agreement in accordance with the amendment provisions of Section 6.4 herein.
