 PROCEDURES TO DETERMINE 

STATE AND CONTRACTOR CONSIDERATIONS 

This Annex establishes the terms and conditions under which the calculations and payment of the applicable Considerations under this Contract shall be carried
out for any Month during the full term of this Contract, under the provisions of the Hydrocarbons Revenue Law prevailing at the time of the awarding of this Contract. 
  

	1.	Contractual Price 

  

	1.1	The Contractual Price for each type of Hydrocarbon will be determined based on the provisions of the Hydrocarbon Revenues Law, in accordance with the procedure established in this Annex 3. 

 

	1.2	Each Period, the Considerations indicated in Articles 16.2 paragraphs (b) and (c), and 16.3 paragraphs (a) and (b), will be calculated based on the Contractual Price of each type of Hydrocarbon, that shall be
determined based on the criteria established in this Annex 3. 

  

	1.3	For purposes of this Annex 3, t shall mean the sub index corresponding to the Period. In case the Petroleum Activities are conducted during a Period which does not encompass a complete Month, the Period shall be
the number of Days during which this Contract was actually in effect. 

  

	1.4	The Contractual Price of Crude Oil per Barrel will be determined as follows: 

  

	 	(a)	In case that during the Period the Contractor markets under Market Rules at least fifty percent (50%) of the Crude Oil volume delivered to it during the Period or there is a commitment for such marketing (including long
term sale contracts under which the price is determined by Market Rules), the Contractual Price of Crude Oil for the Period in which the marketing is registered shall be equal to the average observed sale price weighted by the corresponding volume,
that the Contractor has marketed or committed to market. 

 In the case of any volume that the Contractor sells or delivers to
an Affiliate or a related party, which is in turn marketed to a third party without any intermediate treatment or processing, the sales price and volume corresponding to such Affiliate or related party transaction with a third party, may be
considered in the calculation of the Contractual Price of Crude Oil during the Period. 
  

	 	(b)	In case that, during the Period, the Contractor does not market under Market Rules at least fifty per cent (50%) of the Crude Oil volume delivered to it in the Period, but the Marketer has registered marketing of the
Crude Oil corresponding to the Contract Area based on Market Rules, the Contractual Price of Crude Oil shall be equal to the average price, weighted by the corresponding volume, reported by the Marketer.

	 	(c)	If at the end of the corresponding Period the Contractor has not registered marketing under Market Rules, of at least fifty percent (50%) of the Crude Oil volume delivered to him during the Period, or by the Marketer,
the Contractual Price of Crude Oil shall be calculated based on the corresponding formula as a function of the API grade and sulfur content corresponding to the Crude Oil extracted within the Contract Area during the Period. The foregoing
considering the prices for Light Louisiana Sweet (LLS) and Brent marker crudes, published during the Period by an international company specialized in the publishing of reference information on prices, according to the following:

  

	 	i.	If the Contractor marketed less than fifty percent (50%) of the Crude Oil volume delivered to it during the Period, or if marketing was carried out by the Contractor or the Marketer with Related Parties, the Contractual
Price of the Crude Oil will be the average of the prices calculated using the corresponding formula at the date of each marketing transaction, using the marker prices for such date, weighted by the volume involved in each transaction carried out
during the Period. 

  

	 	ii.	If there was no marketing because the volume of Crude Oil produced in the period and registered at the Measurement Point was kept in storage under the ownership of the Contractor or the Marketer, the Contractual Price
of Crude Oil will be calculated using the corresponding formula, considering the simple average of the marker prices during the Period. 

The referenced formulas to calculate the Contractual Price of the Crude Oil are: 

 
 

 
 Where: 
  

					
	 PCP,t
	  	=	  	Contractual Price of Crude Oil in Period t.
			
	 API
	  	=	  	Adjustment parameter for quality, using weighted average API Grade of Crude Oil produced in the Contract Area.

	  LLS t
	  	=	  	Average market price of Louisiana Light Sweet Crude (LLS) in Period t.
			
	  Brent t
	  	=	  	Average market price of Brent Crude [ICE] in Period t.
			
	  S
	  	=	  	Adjustment parameter for quality, using the value of the weighted average sulfur content of the Crude Oil produced in the Contract Area, Area using two decimal points (for example, 3.00 will be used for 3%).

 The formulas to calculate the Contractual Price may be updated in this Contract to reflect the structural
adjustments in the Hydrocarbons market, based on the information that the Ministry of Finance publishes in the annual report referenced in article 5 of the Hydrocarbon Revenues Law. 

In case that prices for LLS and Brent marker crudes are no longer published, the Ministry of Finance shall establish a new formula taking into
account other marker crudes that have trading liquidity and reflect market conditions. 
 In case a Crude Oil in the market has the same
quality characteristics (same API grade and sulfur content) than that of the Crude Oil produced in the Contract Area during the corresponding Period, the Contractual Price of Crude Oil used according to this subparagraph (c), may be calculated
considering the referenced market price that is Free On Board (FOB), instead of estimated value using the corresponding formula. 
 Regarding
the previous paragraph, the Contractor must present the documents with the verifiable information, published during the Period by an international company specialized in publishing reference information on prices, which proves that the proposed
Crude Oil has the same API grade and sulfur content than that of the Crude Oil produced in the Contract Area, according to the measurements carried out by CNH during the Period. 

 

	 	(d)	In case that the Contractual Price of Crude Oil in the immediately preceding Period or in the two immediately preceding Periods was determined using the formulas established in subparagraph (c) of this subsection,
and that during the Period there is marketing of Crude Oil under Market Rules by the Contractor or the Marketer in accordance with subparagraphs (a) and (b) of this subsection, the Contractual Price of Crude Oil in the Period will be determined
using the following formula, as long as the difference between the estimated price based on the formula and the observed price during the marketing of Crude Oil based on Market Rules during Period t is less than or equal to fifty per cent
(50%) of the observed price:

	 	(c)	If at the end of the Period neither the Contractor or the Marketer have registered marketing under Market Rules of at least fifty percent (50%) of the volume of Condensates delivered to the Contractor, during the
Period, the Contractual Price shall be calculated considering the average price for Brent marker crude published during Period t by an international company specialized in the publishing of reference information on prices, according to
the following: 

  

	 	i.	If the Contractor marketed less than fifty percent (50%) of the volume of Condensates delivered to it in the Period, and the Marketer performed no transaction, or if marketing was carried out by the Contractor or
Marketer with related parties, the Contractual Price of the Condensates will be the average of the prices calculated using the formula at the date of each marketing transaction, using the crude marker price at such date, weighted by the volume
involved in each transaction carried out during the Period. 

  

	 	ii.	If there was no marketing because the volume of Condensates produced during the Period and registered at the Measurement Point was kept in storage under the ownership of the Contractor or the Marketer, the Contractual
Price of the Condensates will be calculated using the corresponding formula, considering the simple average of the marker price during the Period.

between the State and the Contractor as provided in the Contract.

be updated in the month of January based on the changes in the United States Producer Price Index, as published by the Bureau of Labor Statistics of the United States of America, with identification number WPU00000000, without seasonal adjustment,
which represents an index of all merchandise or, if applicable, its substitute index by decision of the issuing institution. In case such price index changes or is revised, the first published version of the index will prevail. If the reference
Index changes, the Ministry of Finance will announce a new reference that is representative for such purposes. 
  

	 	1.6.	In the event that, in any contracting conducted under the procedures referred to in sections II and III of the preceding subsection, the Costs increase due to unforeseen circumstances, the Contractor shall observe the
following: 

  

	 	I.	If the Costs increase by an amount equal to or lower than 5% (five percent), but are not higher than the benchmarks or market prices, in accordance with the analysis previously performed, it will not be necessary to
justify such increase; 

  

	 	II.	If the Costs increase by an amount greater than 5% (five percent), but are not higher than the benchmarks or market prices, in accordance with the analysis previously performed, it will be necessary to justify such
increase, and 

  

	 	III.	If the increase in Costs is higher than the benchmarks or market prices, the portion of the Costs beyond the range shall not be considered as Recoverable Costs. 

 

	 	1.7	The Operator may directly allocate the contract or acquisition to a related party or a third party, without the need for a contest or bidding process, so long as it is first demonstrated that the bid submitted by the
related party or third party offers a price or consideration that is not higher than the benchmarks or market prices, amounts of consideration or profit margins found in reasonable markets, in accordance with the interquartile method procedure under
the Applicable Laws and, if applicable, the benefits arising from such contracts are reflected in lower Costs to recover. 

If under an accounting and financial verification it is identified that the value of the price is higher than the market benchmark or price,
the difference will not be considered as a Recoverable Cost. 
 In the case of contracting goods and/or services with prices regulated by
the State and no other purchase option exists, the Contractor may carry out make such contracts without a contest or bidding process and without conducting preceding studies.

	 	1.8	If, instead of choosing to conduct any contracting under procedures II and III of subsection 1.5, the Operator directly allocates the procurement of goods and/or services to a related party or third party, the criteria
in subsection 1.6 of this Annex will apply if there are increases in Costs. 

 Any analysis or study with the purpose of
showing that an acquisition or contract is at reference values for transactions with third parties or at market prices for related parties must be accompanied by all information to permit replication of the results obtained, as well as the criteria
followed in its preparation. If the information that the Operator provides is insufficient for the Ministry of Finance to replicate the results, the difference above the median value of the relevant Cost, in accordance with the interquartile method
procedure under the Applicable Laws, shall not be considered as Recoverable Cost.

HISTOGENICS CORPORATION 

$10,000,000 
 EQUITY
DISTRIBUTION AGREEMENT 
 March 15, 2018 
 Canaccord
Genuity Inc. 
 99 High Street, Suite 1200 
 Boston,
Massachusetts 02110 
 Ladies and Gentlemen: 

Histogenics Corporation, a Delaware corporation (the “Company”), confirms its agreement (this “Agreement”)
with Canaccord Genuity Inc. (“Canaccord”), as follows: 
 1. Issuance and Sale of Shares. The Company agrees that, from time to time
during the term of this Agreement, on the terms and subject to the conditions set forth herein, it will issue and sell through Canaccord, acting as sales agent, shares (the “Shares”) of the Company’s common stock, $0.01 par
value per share (the “Common Stock”) having an aggregate offering price of up to $10,000,000. The Shares will be sold on the terms set forth herein at such times and in such amounts as the Company and Canaccord shall agree from time
to time. The issuance and sale of the Shares through Canaccord will be effected pursuant to the Registration Statement (as defined below) filed by the Company and declared effective by the Securities and Exchange Commission (the
“Commission”). 
 2. Placements. 
  

	 	(a)	 Placement Notice. Each time that the Company wishes to issue and sell Shares hereunder (each, a
“Placement”), it will notify Canaccord by e-mail notice (or other method mutually agreed to in writing by the parties) containing the parameters within which it desires to sell the Shares,
which shall at a minimum include the number of Shares (“Placement Shares”) to be issued, the time period during which sales are requested to be made, any limitation on the number of Shares that may be sold in any one day and any
minimum price below which sales may not be made (a “Placement Notice”), a form of which shall be mutually agreed upon by the Company and Canaccord. The Placement Notice shall originate from any of the individuals (each an
“Authorized Representative”) from the Company set forth on Schedule 1 (with a copy to each of the other individuals from the Company listed on such schedule), and shall be addressed to each of the

	 	
individuals from Canaccord set forth on Schedule 1 attached hereto, as such Schedule 1 may be amended from time to time. The Placement Notice
shall be effective upon confirmation by Canaccord unless and until (i) Canaccord declines to accept the terms contained therein for any reason, in its sole discretion, in accordance with the notice requirements set forth in
Section 4, (ii) the entire amount of the Placement Shares have been sold, (iii) the Company suspends or terminates the Placement Notice in accordance with the notice requirements set forth in
Section 4, (iv) the Company issues a subsequent Placement Notice with parameters superseding those on the earlier dated Placement Notice, or (v) the Agreement has been terminated under the provisions of
Section 12. 

  

	 	(i)	Placement Fee. The amount of compensation to be paid by the Company to Canaccord with respect to each Placement (in addition to any expense reimbursement pursuant to Section 7(i)(ii))
shall be equal to 3.0% of gross proceeds from each Placement. 

  

	 	(ii)	No Obligation. It is expressly acknowledged and agreed that neither the Company nor Canaccord will have any obligation whatsoever with respect to a Placement or any Placement Shares unless and until the Company
delivers a Placement Notice to Canaccord, and then only upon the terms specified therein and herein. It is also expressly acknowledged that Canaccord will be under no obligation to purchase Shares on a principal basis. In the event of a conflict
between the terms of this Agreement and the terms of a Placement Notice, the terms of the Placement Notice control. 

 3. Sale of Placement
Shares by Canaccord. Subject to the terms and conditions of this Agreement, upon the Company’s issuance of a Placement Notice, and unless the sale of the Placement Shares described therein has been declined, suspended, or otherwise
terminated in accordance with the terms of this Agreement, Canaccord will use its commercially reasonable efforts consistent with its normal trading and sales practices to sell on behalf of the Company and as agent, such Placement Shares up to the
amount specified, and otherwise in accordance with the terms of such Placement Notice. The Company acknowledges that Canaccord will conduct the sale of Placement Shares in compliance with applicable law including, without limitation, Regulation M
under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and that such compliance may include a delay in commencement of sales efforts after receipt of a Placement Notice. Canaccord will provide written
confirmation to the Company no later than the opening of the Trading Day next following the Trading Day on which they have made sales of Placement Shares hereunder setting forth the number of Placement Shares sold on such day, the compensation
payable by the Company to Canaccord with respect to such sales, and the Net Proceeds (as defined below) payable to the Company. Canaccord may sell Placement Shares by any method permitted by law deemed to be an “at the market” offering
under Rule 415 of the Securities Act of 1933, as amended (the “Securities Act”), including without limitation sales made directly on or through The Nasdaq Capital Market (the “Principal Trading Market”), on any
other existing trading market for the Common Stock, sales to or through a market maker other than on an exchange or in negotiated transactions at market prices prevailing at the time of sale or at prices related to such prevailing market prices.
Notwithstanding anything to the 

  
 -2- 

 
contrary set forth in this Agreement or a Placement Notice, the Company acknowledges and agrees that (i) there can be no assurance that Canaccord will be successful in selling any Placement
Shares or as to the price at which any Placement Shares are sold, if at all, and (ii) Canaccord will incur no liability or obligation to the Company or any other person or entity if they do not sell Placement Shares for any reason other than a
failure by Canaccord to use its commercially reasonable efforts consistent with its normal trading and sales practices to sell on behalf of the Company and as agent such Placement Shares as provided under this Section 3.
For the purposes hereof, “Trading Day” means any day on which the Principal Trading Market is open for trading. 
 4. Suspension of
Sales. The Company or Canaccord may, upon notice to the other party in writing, by telephone (confirmed immediately by verifiable facsimile transmission or e-mail) or by
e-mail notice (or other method mutually agreed to in writing by the parties), suspend any sale of Placement Shares; provided, however, that such suspension shall not affect or impair either party’s
obligations with respect to any Placement Shares sold hereunder prior to the receipt of such notice. The Company agrees that no such notice shall be effective against Canaccord unless it is made to one of the individuals named on
Schedule 1 hereto, as such Schedule may be amended from time to time. 
 5. Settlement. 

 

	 	(a)	Settlement of Placement Shares. Unless otherwise specified in the applicable Placement Notice, settlement for sales of Placement Shares will occur on the third (3rd) Business Day (or such earlier day as is agreed
by the parties to be industry practice for regular-way trading) following the date on which such sales are made (each a “Settlement Date”). The amount of proceeds to be delivered to the
Company on a Settlement Date against the receipt of the Placement Shares sold (“Net Proceeds”) will be equal to the aggregate sales price at which such Placement Shares were sold, after deduction for (i) the commission or other
compensation for such sales payable by the Company to Canaccord, as the case may be, pursuant to Section 2 hereof, as the case may be, (ii) any other amounts due and payable by the Company to Canaccord hereunder
pursuant to Section 7(i) hereof, and (iii) any transaction fees imposed by any governmental or self-regulatory organization in respect of such sales. 

 

	 	(b)	 Delivery of Shares. On each Settlement Date, the Company will, or will cause its transfer agent to,
electronically transfer the Placement Shares being sold by crediting Canaccord’s accounts or its designee’s account at The Depository Trust Company through its Deposit Withdrawal Agent Commission System or by such other means of delivery
as may be mutually agreed upon by the parties hereto and, upon receipt of such Placement Shares, which in all cases shall be freely tradeable, transferable, registered shares in good deliverable form, Canaccord will, on each Settlement Date, deliver
the related Net Proceeds in same day funds delivered to an account designated by the Company prior to the Settlement Date. If the Company defaults in its obligation to deliver Placement Shares on a Settlement Date, the Company agrees that in
addition to and in no way limiting the rights and obligations set forth in Section 10 hereto, it will (i) hold Canaccord 

  
 -3- 

	 	
harmless against any loss, claim, damage, or expense (including legal fees and expenses), as incurred, arising out of or in connection with such default by the Company and (ii) pay to
Canaccord any commission, discount, or other compensation to which it would otherwise have been entitled absent such default. 

 6.
Representations and Warranties of the Company. The Company represents and warrants to, and agrees with, Canaccord that: 
  

	 	(a)	 Registration Statement and Prospectus. The Common Stock is registered pursuant to Section 12(b) of
the Exchange Act, and the Company has filed all reports, schedules, forms, statements and other documents required to be filed by it with the Commission (the “Commission Documents”) since the Company has been subject to the
requirements of Section 12 of the Exchange Act, and all of such filings required to be filed within the last 12 months have been made on a timely basis. The Common Stock is currently quoted on the Principal Trading Market under the trading
symbol “HSGX”. The Company and the transactions contemplated hereby meet the requirements for use of Form S-3 under the Securities Act and the rules and regulations thereunder or the interpretations
thereof by the Commission (“Rules and Regulations”), including but not limited to the transaction requirements for an offering made by the issuer set forth in Instruction I.B.6 to Form S-3.
The Company has prepared and filed with the Commission a registration statement on Form S-3 (Registration Number 333-216741) with respect to the Shares to be offered and
sold by the Company pursuant to this Agreement. Such registration statement, at any given time, including the amendments thereto at such time, the exhibits and any schedules thereto at such time, the documents incorporated by reference therein
pursuant to Item 12 of Form S-3 under the Securities Act at such time and the documents otherwise deemed to be a part thereof or included therein by the Rules and Regulations, is herein called the
“Registration Statement.” The Registration Statement, including the base prospectus contained therein (the “Base Prospectus”) was prepared by the Company in conformity with the requirements of the Securities Act and
all applicable Rules and Regulations. One or more prospectus supplements relating to the Shares (the “Prospectus Supplements,” and together with the Base Prospectus and any amendment thereto and all documents incorporated therein by
reference, the “Prospectus”) have been or will be prepared by the Company in conformity with the requirements of the Securities Act and all applicable Rules and Regulations and have been or will be filed with the Commission in the
manner and time frame required by the Securities Act and the Rules and Regulations. Any amendment or supplement to the Registration Statement or Prospectus required by this Agreement will be so prepared and filed by the Company and, as applicable,
the Company will use commercially reasonable efforts to cause it to become effective as soon as reasonably practicable. No stop order suspending the effectiveness of the Registration Statement has been issued, and no proceeding for that purpose has
been instituted or, to the knowledge of the Company, threatened by the Commission. No order preventing or suspending the use of the Base Prospectus, the Prospectus Supplement, the Prospectus or any Issuer Free Writing Prospectus (as defined

  
 -4- 

	 	
herein) has been issued by the Commission. Copies of all filings made by the Company under the Securities Act and all Commission Documents that were filed with the Commission have either been
delivered to Canaccord or made available to Canaccord on the Commission’s Electronic Data Gathering, Analysis, and Retrieval system (“EDGAR”). Any reference herein to the Registration Statement, the Prospectus, or any amendment
or supplement thereto shall be deemed to refer to and include the documents incorporated (or deemed to be incorporated) by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, and any
reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement or Prospectus shall be deemed to refer to and include the filing after the execution hereof of any document
with the Commission deemed to be incorporated by reference therein. For the purposes of this Agreement, the “Applicable Time” means, with respect to any Shares, the time of sale of such Shares pursuant to this Agreement.

  

	 	(b)	No Misstatement or Omission. Each part of the Registration Statement, when such part became or becomes effective, at any deemed effective date pursuant to Rule 430B(f)(2) on the date of filing thereof with the
Commission and at each Applicable Time and Settlement Date, and the Prospectus, on the date of filing thereof with the Commission and at each Applicable Time and Settlement Date, conformed or will conform in all material respects with the
requirements of the Securities Act and the Rules and Regulations; each part of the Registration Statement, when such part became or becomes effective, did not or will not contain an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein not misleading; and the Prospectus, on the date of filing thereof with the Commission, and the Prospectus and the applicable Issuer Free Writing Prospectus(es) issued at
or prior to such Applicable Time, taken together (collectively, and with respect to any Shares, together with the public offering price of such Shares, the “Disclosure Package”) and at each Applicable Time and Settlement Date, did
not or will not include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; except that the foregoing shall not
apply to statements or omissions in any such document made in reliance on information furnished in writing to the Company by Canaccord expressly stating that such information is intended for use in the Registration Statement, the Prospectus, or any
amendment or supplement thereto, or in any Issuer Free Writing Prospectus(es). 

  

	 	(c)	 Conformity with Securities Act and Exchange Act. The documents incorporated by reference in the
Registration Statement or the Prospectus, or any amendment or supplement thereto, when they became effective under the Securities Act or were filed with the Commission under the Exchange Act, as the case may be, conformed in all material respects
with the requirements of the Securities Act or the Exchange Act, as applicable, and the rules and regulations of the Commission promulgated under the Exchange Act or the interpretations thereof by the Commission (the “Exchange Act

intended for use in any such document.

	 	(yy)	Clinical Studies. The clinical, pre-clinical and other studies and tests conducted by or on behalf of the Company, any of its Subsidiaries or in which the Company or its
products or product candidates has participated, were and, if still pending, are being conducted in material accordance with experimental protocols, procedures and controls and in material accordance with all applicable local, state, federal and
foreign laws, rules, regulations and guidance, including, without limitation, the FFDCA. None of the descriptions of the tests and preclinical and clinical studies, conducted by or on behalf of the Company contained in the Registration Statement,
the Disclosure Package and the Prospectus contains an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading. The Company is not aware of any
studies, tests or trials the results of which the Company believes reasonably call into question the study, test or trial results described or referred to in the Registration Statement, the Disclosure Package and the Prospectus when viewed in the
context in which such results are described and the clinical state of development. Except to the extent disclosed in the Registration Statement, the Disclosure Package and the Prospectus, no investigational device exemption filed by or on behalf of
the Company with the FDA or a Governmental Entity has been terminated or suspended by the FDA or Governmental Entity, and neither the FDA nor any Governmental Entity has commenced, or, to the knowledge of the Company, threatened to initiate, any
action to place a clinical hold order on, or otherwise terminate or suspend any ongoing studies, tests or preclinical or clinical trials or investigations conducted or proposed to be conducted by or on behalf of the Company or any of its
Subsidiaries. 

  

	 	(zz)	Lending Relationship. Except as disclosed in the Registration Statement, the Disclosure Package and the Prospectus, the Company (A) does not have any material lending or other relationship with any bank or
lending affiliate of Canaccord and (B) does not intend to use any of the proceeds from the sale of the Placement Shares to repay any outstanding debt owed to any affiliate of Canaccord. 

 

	 	(aaa)	Statistical and Market-Related Data. Any statistical and market-related data included in the Registration Statement, the Disclosure Package or the Prospectus are based on or derived from sources that the Company
believes, after reasonable inquiry, to be reliable and accurate in all material respects and, to the extent required, the Company has obtained the written consent to the use of such data from such sources. 

  
 -23- 

	 	(bbb)	Maintenance of Rating. The Company does not have any securities rated by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) under the Securities Act).

  

	 	(ccc)	Related Party Transactions. There are no business relationships or related-party transactions involving the Company, any of the Subsidiaries or any other person required to be described in the Registration
Statement, the Prospectus and the Disclosure Package which have not been described as required. The Disclosure Package contains in all material respects the same description of the matters set forth in the preceding sentence contained in the
Prospectus. 

  

	 	(ddd)	Margin Rules. The application of the proceeds received by the Company from the issuance, sale and delivery of the Placement Shares as described in the Registration Statement, the Disclosure Package and the
Prospectus will not violate Regulation T, U or X of the Board of Governors of the Federal Reserve System or any other regulation of such Board of Governors. 

7. Covenants of the Company. The Company covenants and agrees with Canaccord that: 

 

	 	(a)	Registration Statement Amendments. After the date of this Agreement and during the period in which a prospectus relating to the Placement Shares is required to be delivered by Canaccord under the Securities Act
(including in circumstances where such requirement may be satisfied pursuant to Rule 172 or Rule 173(a) under the Securities Act), (i) the Company will notify Canaccord promptly of the time when any subsequent amendment to the Registration Statement
has been filed with the Commission and has become effective (each, a “Registration Statement Amendment Date”) or any subsequent supplement to the Prospectus has been filed and of any request by the Commission for any amendment or
supplement to the Registration Statement or Prospectus or for additional information; (ii) the Company will file promptly all other material required to be filed by it with the Commission pursuant to Rule 433(d) under the Securities Act;
(iii) it will prepare and file with the Commission, promptly upon Canaccord’s request, any amendments or supplements to the Registration Statement or Prospectus that, in Canaccord’s reasonable opinion, may be necessary or advisable in
connection with the distribution of the Placement Shares by Canaccord (provided, however that the failure of Canaccord to make such request shall not relieve the Company of any obligation or liability hereunder, or affect Canaccord’s right to
rely on the representations and warranties made by the Company in this Agreement); and (iv) the Company will submit to Canaccord a copy of any amendment or supplement to the Registration Statement or Prospectus a reasonable period of time
before the filing thereof and will afford Canaccord and Canaccord’s counsel a reasonable opportunity to comment on any such proposed filing prior to such proposed filing; and the Company will cause each amendment or supplement to the Prospectus
to be filed with the Commission as required pursuant to the applicable paragraph of Rule 424 (b) of the Rules and Regulations or, in the case of any document to be incorporated therein by reference, to be filed with the Commission as required
pursuant to the Exchange Act, within the time period prescribed. 

  
 -24- 

	 	(b)	Notice of Commission Stop Orders. The Company will advise Canaccord, promptly after it receives notice thereof, of the issuance by the Commission of any stop order or of any order preventing or suspending the use
of the Prospectus or other prospectus in respect of the Shares, of any notice of objection of the Commission to the use of the form of the Registration Statement or any post-effective amendment thereto
pursuant to Rule 401(g)(2) under the Securities Act, of the suspension of the qualification of the Shares for offering or sale in any jurisdiction, of the initiation or threatening of any proceeding for any such purpose, or of any request by the
Commission for the amending or supplementing of the form of the Registration Statement or the Prospectus or for additional information; and, in the event of the issuance of any such stop order or of any such order preventing or suspending the use of
the Prospectus in respect of the Shares or suspending any such qualification, to promptly use its commercially reasonable efforts to obtain the withdrawal of such order; and in the event of any such issuance of a notice of objection, promptly to
take such reasonable steps as may be necessary to permit offers and sales of the Placement Shares by Canaccord, which may include, without limitation, amending the Registration Statement or filing a new registration statement, at the Company’s
expense (references herein to the Registration Statement shall include any such amendment or new registration statement). 

  

	 	(c)	Delivery of Prospectus; Subsequent Changes. Within the time during which a prospectus relating to the Placement Shares is required to be delivered by Canaccord under the Securities Act (including in circumstances
where such requirement may be satisfied pursuant to Rule 172 or Rule 173(a) under the Securities Act), the Company will comply with all requirements imposed upon it by the Securities Act and by the Rules and Regulations, as from time to time in
force, and will file on or before their respective due dates all reports required to be filed by it with the Commission pursuant to Sections 13(a), 13(c), 15(d), if applicable, or any other provision of or under the Exchange Act. If during such
period any event occurs as a result of which the Prospectus as then amended or supplemented would include an untrue statement of material fact or omit to state a material fact necessary to make the statements therein, in the light of the
circumstances then existing, not misleading, or if during such period it is necessary to amend or supplement the Registration Statement or Prospectus to comply with the Securities Act, the Company will immediately notify Canaccord to suspend the
offering of Shares during such period and the Company will promptly amend or supplement the Registration Statement or Prospectus (at the expense of the Company) so as to correct such statement or omission or effect such compliance.

  

	 	(d)	Nasdaq Filings. In connection with the offering and sale of the Placement Shares, the Company will file with The Nasdaq Capital Market all documents and notices, and make all certifications, required by The
Nasdaq Capital Market of companies that have securities that are listed on The Nasdaq Capital Market. 

  
 -25- 

	 	(e)	Listing of Placement Shares. The Company will use commercially reasonable efforts to cause the Placement Shares to be listed on the Principal Trading Market and to qualify the Placement Shares for sale under the
securities laws of such jurisdictions as Canaccord designates and to continue such qualifications in effect so long as required for the distribution of the Placement Shares; provided that the Company shall not be required in connection therewith to
qualify as a foreign corporation or other entity or as a dealer in securities in any such jurisdiction where it would not otherwise be required to so qualify or to file a general consent to service of process in any such jurisdiction or subject
itself to taxation in any such jurisdiction if it is not otherwise so subject. 

  

	 	(f)	Delivery of Registration Statement and Prospectus. The Company will furnish to Canaccord and its counsel (at the expense of the Company) copies of the Registration Statement, the Prospectus (including all
documents incorporated by reference therein) and all amendments and supplements to the Registration Statement or Prospectus that are filed with the Commission during the period in which a prospectus relating to the Shares is required to be delivered
under the Securities Act (including all documents filed with the Commission during such period that are deemed to be incorporated by reference therein), in each case as soon as reasonably practicable and in such quantities as Canaccord may from time
to time reasonably request and, at Canaccord’s request, will also furnish copies of the Prospectus to each exchange or market on which sales of Placement Shares may be made. 

 

	 	(g)	Company Information. The Company will furnish to Canaccord for a period of one (1) year from the date of this Agreement such information as is furnished to holders of the Shares or furnished to or filed with
the Commission or any national securities exchange or automatic quotation system and is reasonably requested by Canaccord regarding the Company or its Subsidiaries. 

 

	 	(h)	Earnings Statement. The Company will make generally available to its security holders as soon as reasonably practicable, but in any event not later than 15 months after the end of the Company’s current
fiscal quarter, an earnings statement covering a 12-month period that satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 of the Rules and Regulations. 

 

	 	(i)	Expenses. 

  

	 	(i)	 The Company, whether or not the transactions contemplated hereunder are consummated or this Agreement is
terminated, will pay or cause to be paid all expenses incident to the performance of its obligations hereunder, including but not limited to (i) the preparation, printing and filing of the Registration Statement and each amendment and
supplement thereto, of each Prospectus and of each amendment and supplement thereto and each 

  
 -26- 

	 	
Issuer Free Writing Prospectus (as defined in Section 8 of this Agreement), (ii) the preparation, issuance and delivery of the Placement Shares, (iii) all fees
and disbursements of the Company’s counsel, accountants and other advisors, (iv) the qualification of the Placement Shares under securities laws in accordance with the provisions of Section 7(e) of this Agreement,
including filing fees in connection therewith, (v) the printing and delivery to Canaccord of copies of the Prospectus and any amendments or supplements thereto, and of this Agreement, (vi) the fees and expenses incurred in connection with
the listing or qualification of the Placement Shares for trading on the Exchange, and (vii) any filing fees and expenses incident to any review by the Financial Industry Regulatory Authority (including reasonable fees and disbursements of
counsel to Canaccord incurred in connection therewith) of the terms of the sale of the Placement Shares. 

  

	 	(ii)	In addition to any fees that may be payable to Canaccord hereunder and regardless of whether or not the transactions contemplated hereunder are consummated or this Agreement is terminated, the Company shall reimburse
Canaccord for all of its reasonable expenses, up to a maximum reimbursement of $50,000, arising out of this Agreement (including travel and related expenses, the costs of document preparation, production and distribution, third party research and
database services and the reasonable fees and disbursements of counsel to Canaccord) within ten (10) days of the presentation by Canaccord to the Company of a reasonably detailed statement therefor. 

 

	 	(j)	Use of Proceeds. The Company will use the Net Proceeds as described in the Prospectus. 

  

	 	(k)	 Other Sales. Without the prior written consent of Canaccord (which consent shall not be unreasonably
withheld, conditioned or delayed), the Company will not (A) directly or indirectly, offer to sell, sell, announce the intention to sell, contract to sell, pledge, lend, grant or sell any option, right or warrant to sell or any contract to
purchase, purchase any contract or option to sell or otherwise transfer or dispose of any shares of Common Stock (other than the Shares offered pursuant to the provisions of this Agreement) or securities convertible into or exchangeable for Common
Stock, warrants or any rights to purchase or acquire, Common Stock or file any registration statement under the Securities Act with respect to any of the foregoing (other than a registration statement on Form
S-8), or (B) enter into any swap or other agreement or any transaction that transfers in whole or in part, directly or indirectly, any of the economic consequence of ownership of the Common Stock, or any
securities convertible into or exchangeable or exercisable for or repayable with Common Stock, whether any such swap or transaction described in clause (A) or (B) above is to be settled by delivery of Common Stock or such other securities, in
cash or otherwise, during the period beginning on the fifth (5th) Business Day immediately prior to the date on which any Placement Notice is delivered by the Company hereunder and 

  
 -27- 

	 	
ending on the fifth (5th) Business Day immediately following the final Settlement Date with respect to Placement Shares sold pursuant to such Placement Notice; and without the prior written
consent of Canaccord (which consent shall not be unreasonably withheld), the Company will not directly or indirectly in any other “at the market” or continuous equity transaction offer to sell, sell, contract to sell, grant any option to
sell or otherwise dispose of any shares of Common Stock (other than the Placement Shares offered pursuant to the provisions of this Agreement) or securities convertible into or exchangeable for Common Stock, warrants or any rights to purchase or
acquire, Common Stock prior to the later of the termination of this Agreement and the thirtieth (30th) day immediately following the final Settlement Date with respect to Placement Shares sold pursuant to such Placement Notice; provided, however,
that such restrictions will not be applicable to the Company’s issuance or sale of (i) Common Stock, options to purchase shares of Common Stock or Common Stock issuable upon the exercise of options, pursuant to any employee or director

hereafter implemented, and (ii) Common Stock issuable upon conversion of securities or the exercise of warrants, options or other rights in effect or outstanding on the date hereof, and disclosed in writing to Canaccord or otherwise disclosed
in the Registration Statement, Prospectus or Disclosure Package.  

  

	 	(l)	Change of Circumstances. The Company will, at any time during the term of this Agreement, as supplemented from time to time, advise Canaccord immediately after it shall have received notice or obtained knowledge
thereof, of any information or fact that would alter or affect any opinion, certificate, letter or other document provided to Canaccord pursuant to this Agreement. 

 

	 	(m)	Due Diligence Cooperation. The Company will cooperate with any due diligence review conducted by Canaccord or its agents, including, without limitation, providing information and making available documents and
senior corporate officers, as Canaccord may reasonably request; provided, however, that the Company shall be required to make available senior corporate officers only (i) by telephone or at the Company’s principal offices and
(ii) during the Company’s ordinary business hours. 

  

	 	(n)	Affirmation of Representations, Warranties, Covenants and Other Agreements. Upon commencement of the offering of the Placement Shares under this Agreement (and upon the recommencement of the offering of the
Placement Shares under this Agreement following any termination of a suspension of sales hereunder), and at each Applicable Time, each Settlement Date, each Registration Statement Amendment Date (as defined below) and each Company Periodic Report
Date (as defined below), in each case, to the extent no waiver is applicable pursuant to Section 7(p), the Company shall be deemed to have affirmed each representation, warranty, covenant and other agreement contained in this Agreement.

  
 -28- 

	 	(o)	Required Filings Relating to Placement of Placement Shares. In each Annual Report on Form 10-K or Quarterly Report on Form 10-Q
filed by the Company in respect of any quarter in which sales of Placement Shares were made by Canaccord under this Agreement (each date on which any such document is filed, and any date on which an amendment to any such document is filed, a
“Company Periodic Report Date”), the Company shall set forth with regard to such quarter the number of Shares sold through the Canaccord under this Agreement, the Net Proceeds received by the Company and the compensation paid by the
Company to Canaccord with respect to sales of Placement Shares pursuant to this Agreement. 

  

	 	(p)	Representation Dates; Certificate. During the term of this Agreement, on the date of each Placement Notice given hereunder, promptly upon each request of Canaccord, and each time the Company (i) files the
Prospectus relating to the Placement Shares or amends or supplements (other than a prospectus supplement relating solely to an offering of securities other than the Placement Shares) the Registration Statement or the Prospectus relating to the
Placement Shares by means of a post-effective amendment, sticker, or supplement but not by means of incorporation of document(s) by reference to the Registration Statement or the Prospectus relating to the Placement Shares; (ii) files an annual
report on Form 10-K under the Exchange Act; (iii) files its quarterly reports on Form 10-Q under the Exchange Act; or (iv) files a report on Form 8-K containing amended financial information (other than an earnings release, to “furnish” information pursuant to Items 2.02 or 7.01 of Form 8-K or to provide
disclosure pursuant to Item 8.01 of Form 8-K relating to the reclassifications of certain properties as discontinued operations in accordance with Statement of Financial Accounting Standards No. 144)
under the Exchange Act (each date of filing of one or more of the documents referred to in clauses (i) through (iv) shall be a “Representation Date”); the Company shall furnish Canaccord (but in the case of clause
(iv) above only if Canaccord reasonably determines that the financial information contained in such Form 8-K is material) with a certificate, in the form attached hereto as Exhibit A. The
requirement to provide a certificate under this Section 7(p) shall be waived for any Representation Date occurring at a time at which no Placement Notice is pending, which waiver shall continue until the earlier to occur of
the date the Company delivers a Placement Notice hereunder (which for such calendar quarter shall be considered a Representation Date) and the next occurring Representation Date; provided, however, that such waiver shall not apply for any
Representation Date on which the Company files its annual report on Form 10-K. Notwithstanding the foregoing, if the Company subsequently decides to sell Placement Shares following a Representation Date
when the Company relied on such waiver and did not provide Canaccord with a certificate under this Section 7(p), then before the Company delivers the Placement Notice or Canaccord sells any Placement Shares, the Company
shall provide Canaccord with a certificate, in the form attached hereto as Exhibit A, dated the date of the Placement Notice. 

  
 -29- 

	 	(q)	Legal Opinions. Upon execution of this Agreement, upon commencement of the offering of Placement Shares under this Agreement (and upon the recommencement of the offering of the Placement Shares under this
Agreement following any termination of a suspension of sales hereunder), and promptly after each (i) Registration Statement Amendment Date, (ii) Company Periodic Report Date, and (iii) each reasonable request by Canaccord, in each
case, to the extent no waiver is applicable pursuant to Section 7(p), the Company will furnish or cause to be furnished to Canaccord the written opinion and negative assurance letter, to the extent applicable, of (a) Gunderson Dettmer
Stough Villeneuve Franklin & Hachigian, LLP, counsel for the Company, and (b) Troutman Sanders LLP, intellectual property counsel for the Company, or other counsel reasonably satisfactory to Canaccord, dated the date of this Agreement
or the date of such commencement or recommencement or the date of effectiveness of such amendment or the date of filing with the Commission of such supplement or other document, as the case may be, in a form and substance reasonably satisfactory to
Canaccord and its counsel; provided, however, in lieu of such opinion and letter, counsel last furnishing such letter to Canaccord shall furnish Canaccord with a letter substantially to the effect that Canaccord may rely on such last opinion and
letter to the same extent as though each were dated the date of such letter authorizing reliance (except that statements in such last letter shall be deemed to relate to the Registration Statement and the Prospectus as amended and supplemented to
the time of delivery of such letter authorizing reliance). As used in this paragraph, to the extent there shall be an Applicable Time on or following the date referred to in clause (i) or (ii) above, promptly shall be deemed to be on or
prior to the next succeeding Applicable Time. Such opinion and negative assurance letter, to the extent applicable, shall be rendered to Canaccord at the request of the Company and shall state so therein. 

 

	 	(r)	Comfort Letters. Upon execution of this Agreement, upon commencement of the offering of Placement Shares under this Agreement (and upon the recommencement of the offering of the Shares under this Agreement
following any termination of a suspension of sales hereunder), and promptly after each (i) Registration Statement Amendment Date, (ii) Company Periodic Report Date, and (iii) each reasonable request by Canaccord, in each case, to the
extent no waiver is applicable pursuant to Section 7(p) the Company shall cause its independent accountants reasonably satisfactory to Canaccord, to furnish Canaccord letters dated the date of this Agreement or the date of such commencement or
recommencement or the date of effectiveness of such amendment or the date of filing of such supplement or other document with the Commission, as the case may be (the “Comfort Letters”), in form and substance satisfactory to
Canaccord, (i) confirming that they are registered independent public accountants within the meaning of the Securities Act and are in compliance with the applicable requirements relating to the qualification of accountants under Rule 2-01 of Regulation S-X of the Commission, (ii) stating, as of such date, the conclusions and findings of such firm with respect to the financial information and other
matters included in or incorporated by reference in the Registration Statement as ordinarily covered by accountants’ “comfort letters” to underwriters in connection with registered public offerings (the first such letter, the
“Initial Comfort Letter”) and (iii) updating the Initial Comfort Letter with any information which would have been included in the Initial Comfort Letter had it been given on such date and modified as necessary to relate to the
Registration Statement and the Prospectus, as amended and supplemented to the date of such letter. 

  
 -30- 

	 	(s)	Market Activities. The Company will not, directly or indirectly, without giving effect to activities by Canaccord, (i) take any action designed to cause or result in, or that constitutes or might reasonably
be expected to constitute, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Shares or (ii) sell, bid for, or purchase the Shares, or pay anyone any compensation for soliciting
purchases of the Shares other than Canaccord. 

  

	 	(t)	Insurance. The Company and its Subsidiaries shall maintain, or cause to be maintained, insurance in such amounts and covering such risks as is reasonable and customary for companies engaged in similar businesses
in similar industries. 

  

	 	(u)	Compliance with Laws. The Company and its Subsidiaries shall comply with all federal, state and local or foreign law, rule, regulation, ordinance, order or decree, except where failure to so comply would not
reasonably be expected to result in a Material Adverse Effect. Furthermore, the Company and its Subsidiaries shall maintain, or cause to be maintained, all material environmental permits, licenses and other material authorizations required by
federal, state and local law in order to conduct their businesses as described in the Prospectus, and the Company and its Subsidiaries shall conduct their businesses, or cause their businesses to be conducted, in substantial compliance with such
material permits, licenses and authorizations and with applicable environmental laws, except where the failure to maintain or be in compliance with such permits, licenses and authorizations would not reasonably be expected, individually or in the
aggregate, to have a Material Adverse Effect. 

  

	 	(v)	Investment Company Act. The Company will conduct its affairs in such a manner so as to reasonably ensure that it will not be or become, at any time prior to the termination of this Agreement, an “investment
company,” as such term is defined in the Investment Company Act, assuming no change in the Commission’s current interpretation as to entities that are not considered an investment company. 

 

	 	(w)	Securities Act and Exchange Act. The Company will use commercially reasonable efforts to comply with all requirements imposed upon it by the Securities Act and the Exchange Act as from time to time in force, so
far as necessary to permit the continuance of sales of, or dealings in, the Shares as contemplated by the provisions hereof and the Prospectus. 

  

	 	(x)	No Offer to Sell. Other than a free writing prospectus (as defined in Rule 405 under the Securities Act) approved in advance by the Company and Canaccord in its capacity as principal or agent hereunder, neither
Canaccord nor the Company (including its agents and representatives, other than Canaccord in its capacity as such) will make, use, prepare, authorize, approve or refer to any written communication (as defined in Rule 405 under the Securities Act),
required to be filed by it with the Commission, that constitutes an offer to sell or solicitation of an offer to buy Common Stock hereunder. 

  
 -31- 

	 	(y)	Sarbanes-Oxley Act. The Company and the Subsidiaries will use their commercially reasonable efforts to comply with all effective applicable provisions of the Sarbanes-Oxley Act. 

 

	 	(z)	Consent to Canaccord Trading. The Company consents to Canaccord trading in the shares of Common Stock of the Company for Canaccord’s own account and for the account of its clients at the same time as sales
of Placement Shares occur pursuant to this Agreement. 

  

	 	(aa)	Rescission Offers. If, to the knowledge of the Company, all filings required by Rule 424 in connection with this offering shall not have been made or the representation in Section 6
shall not be true and correct on the applicable Settlement Date, the Company will offer to any person who has agreed to purchase Placement Shares from the Company as the result of an offer to purchase solicited by Canaccord the right to refuse to
purchase and pay for such Placement Shares. 

  

	 	(bb)	Actively Traded Security. If, at the time of execution of this Agreement, the Company’s Common Stock is not an “actively traded security” exempted from the requirements of Rule 101 of Regulation M
under the Exchange Act by subsection (c)(1) of such rule, the Company shall notify Canaccord at the time the Common Stock becomes an “actively traded security” under such rule. Furthermore, the Company shall notify Canaccord immediately if
the Common Stock, having once qualified for such exemption, ceases to so qualify. 

  

	 	(cc)	Blue Sky Qualifications. The Company will use its commercially reasonable efforts, in cooperation with Canaccord, to qualify the Placement Shares for sale under the applicable securities laws of such states and
other jurisdictions (domestic or foreign) as Canaccord may designate and to maintain such qualifications in effect so long as required to complete the sale of the Placement Shares; provided, however, that the Company shall not be obligated to file
any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in
which it is not otherwise so subject. 

  

	 	(dd)	Emerging Growth Company Status. The Company will promptly notify Canaccord if the Company ceases to be an Emerging Growth Company at any time prior to the termination of this Agreement. 

  
 -32- 

 8. Additional Representations and Covenants of the Company. 

 

	 	(a)	Issuer Free Writing Prospectuses. 

  

	 	(i)	The Company represents that it has not made, and covenants that, unless it obtains the prior written consent of Canaccord, it will not make any offer relating to the Shares that would constitute a “free writing
prospectus” (as defined in Rule 405 of the Securities Act) (an “Issuer Free Writing Prospectus”) required to be filed by it with the Commission or retained by the Company under Rule 433 of the Securities Act; except as set
forth in a Placement Notice, no use of any Issuer Free Writing Prospectus has been consented to by Canaccord. The Company agrees that it will comply with the requirements of Rules 164 and 433 of the Securities Act applicable to any Issuer Free
Writing Prospectus, including timely filing with the Commission or retention where required and legending. 

  

	 	(ii)	The Company agrees that no Issuer Free Writing Prospectus, if any, will include any information that conflicts with the information contained in the Registration Statement, including any document incorporated by
reference therein that has not been superseded or modified, or the Prospectus. In addition, no Issuer Free Writing Prospectus, if any, will include an untrue statement of a material fact or omit to state a material fact necessary to make the
statements therein, in light of the circumstances under which they were made, not misleading; provided however, the foregoing shall not apply to any statements or omissions in any Issuer Free Writing Prospectus made in reliance on information
furnished in writing to the Company by Canaccord expressly stating that such information is intended for use therein. 

  

	 	(iii)	The Company agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in
the Registration Statement, including any document incorporated by reference therein that has not been superseded or modified, or the Prospectus or would include an untrue statement of a material fact or omit to state a material fact necessary to
make the statements therein, in light of the circumstances under which they were made, not misleading, the Company will give prompt notice thereof to Canaccord and, if requested by Canaccord, will prepare and furnish without charge to Canaccord an
Issuer Free Writing Prospectus or other document which will correct such conflict, statement or omission; provided, however, the foregoing shall not apply to any statements or omissions in any Issuer Free Writing Prospectus made in reliance on
information furnished in writing to the Company by Canaccord expressly stating that such information is intended for use therein. 

  

	 	(b)	 Non-Issuer Free Writing Prospectus. The Company consents to the
use by Canaccord of a free writing prospectus that (a) is not an “Issuer Free Writing Prospectus” as defined in Rule 433 under the Securities Act, and (b) contains only information describing the preliminary terms of the Shares
or their offering, or information permitted under Rule 134 under the Securities Act; provided that 

  
 -33- 

	 	
Canaccord covenants with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) under the Securities Act a free writing
prospectus prepared by or on behalf of Canaccord that otherwise would not be required to be filed by the Company thereunder, but for the action of Canaccord. 

  

	 	(c)	Distribution of Offering Materials. The Company has not distributed and will not distribute, during the term of this Agreement, any offering materials in connection with the offering and sale of the Placement
Shares other than the Registration Statement, Prospectus or any Issuer Free Writing Prospectus reviewed and consented to by Canaccord and included in a Placement Notice (as described in clause (a)(i) above). 

9. Conditions to Canaccord’s Obligations. The obligations of Canaccord hereunder with respect to a Placement will be subject to the continuing
accuracy and completeness of the representations and warranties made by the Company herein and in the applicable Placement Notices, to the due performance by the Company of its obligations hereunder, to the completion by Canaccord of a due diligence
review satisfactory to Canaccord in its reasonable judgment, and to the continuing satisfaction (or waiver by Canaccord in its sole discretion) of the following additional conditions: 

 

	 	(a)	Registration Statement Effective. The Registration Statement shall have become effective and shall be available for the sale of (i) all Placement Shares issued pursuant to all prior Placements and not yet
sold by Canaccord and (ii) all Placement Shares contemplated to be issued by the Placement Notice relating to such Placement. 

  

	 	(b)	 No Material Notices. None of the following events shall have occurred and be continuing: (i) receipt
by the Company of any request for additional information from the Commission or any other federal or state or foreign or other governmental, administrative or self-regulatory authority during the period of effectiveness of the Registration
Statement, the response to which might reasonably require any amendments or supplements to the Registration Statement or the Prospectus; (ii) the issuance by the Commission or any other federal or state or foreign or other governmental
authority of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; (iii) receipt by the Company of any notification with respect to the suspension of the qualification
or exemption from qualification of any of the Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; (iv) the occurrence of any event that makes any statement made in the Registration Statement
or the Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making of any changes in the Registration Statement, related prospectus or documents so that, in the
case of the Registration Statement, 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 not misleading, and in the case of the
Prospectus, it will not 

  
 -34- 

	 	
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 light of the circumstances
under which they were made, not misleading; and (v) the Company’s reasonable determination that a post-effective amendment to the Registration Statement would be appropriate. 

 

	 	(c)	No Misstatement or Material Omission. Canaccord shall not have advised the Company that the Registration Statement or Prospectus, or any amendment or supplement thereto, contains an untrue statement of fact that
in Canaccord’s opinion is material, or omits to state a fact that in Canaccord’s opinion is material and is required to be stated therein or is necessary to make the statements therein not misleading. 

 

	 	(d)	Material Changes. Except as contemplated and appropriately disclosed in the Prospectus, or disclosed in the Company’s reports filed with the Commission, in each case at the time the applicable Placement
Notice is delivered, there shall not have been any material change, on a consolidated basis, in the authorized capital stock of the Company and its Subsidiaries, or any Material Adverse Effect, or any development that may reasonably be expected to
cause a Material Adverse Effect, or a downgrading in or withdrawal of the rating assigned to any of the Company’s securities by any rating organization or a public announcement by any rating organization that it has under surveillance or review
its rating of any of the Company’s securities, the effect of which, in the sole judgment of Canaccord (without relieving the Company of any obligation or liability it may otherwise have), is so material as to make it impracticable or
inadvisable to proceed with the offering of the Placement Shares on the terms and in the manner contemplated in the Prospectus. 

  

	 	(e)	Certificate. Canaccord shall have received the certificate required to be delivered pursuant to Section 7(p) on or before the date on which delivery of such certificate is required
pursuant to Section 7(p). 

  

	 	(f)	Legal Opinions. Canaccord shall have received the opinions of counsel to the Company required to be delivered pursuant Section 7(q) on or before the date on which such delivery of such
opinions are required pursuant to Section 7(q). In addition, Canaccord shall have received the opinion of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., counsel to Canaccord, on such dates and with respect to such
matters as Canaccord may reasonably request. 

  

	 	(g)	Comfort Letters. Canaccord shall have received the Comfort Letter required to be delivered pursuant Section 7(r) on or before the date on which such delivery of such letter is required
pursuant to Section 7(r). 

  

	 	(h)	Approval for Listing; No Suspension. The Placement Shares shall have either been (i) approved for listing, subject to notice of issuance, on the Principal Trading Market, or (ii) the Company shall have
filed an application for listing of the Placement Shares on the Principal Trading Market at or prior to the issuance of the Placement Notice. Trading in the Common Stock shall not have been suspended on such market. 

  
 -35- 

	 	(i)	Other Materials. On each date on which the Company is required to deliver a certificate pursuant to Section 7(p), the Company shall have furnished to Canaccord such appropriate further
information, certificates, opinions and documents as Canaccord may reasonably request. All such opinions, certificates, letters and other documents will be in compliance with the provisions hereof. The Company will furnish Canaccord with such
conformed copies of such opinions, certificates, letters and other documents as Canaccord shall reasonably request. 

  

	 	(j)	Securities Act Filings Made. All filings with the Commission required by Rule 424 under the Securities Act to have been filed prior to the issuance of any Placement Notice hereunder shall have been made within
the applicable time period prescribed for such filing by Rule 424. 

  

	 	(k)	No Termination Event. There shall not have occurred any event that would permit Canaccord to terminate this Agreement pursuant to Section 12(a). 

10. Indemnification and Contribution. 
  

	 	(a)	 Company Indemnification. The Company will indemnify and hold harmless Canaccord and each person, if any,
who controls Canaccord against any losses, claims, damages or liabilities, joint or several, to which Canaccord or controlling person may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus, the Disclosure Package, or any Issuer Free Writing Prospectus
or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or any amendment or supplement to the Registration Statement, the Prospectus or the Disclosure Package, or in any application or
other document executed by or on behalf of the Company or based on written information furnished by or on behalf of the Company filed in any jurisdiction in order to qualify the Placement Shares under the securities laws thereof or filed with the
Commission, or arise out of or are based upon the omission or alleged omission to state in the Registration Statement, the Prospectus, the Disclosure Package, or any Issuer Free Writing Prospectus or any “issuer information” filed or
required to be filed pursuant to Rule 433(d) under the Securities Act, or any amendment or supplement to the Registration Statement, the Prospectus, or the Disclosure Package or in any application or other document executed by or on behalf of the
Company or based on written information furnished by or on behalf of the Company filed in any jurisdiction in order to qualify the Placement Shares under the securities laws thereof or filed with the Commission a material fact required to be stated
in it or necessary to make the statements in it not misleading, and will reimburse Canaccord for any reasonable legal expenses of counsel for Canaccord, and for other expenses reasonably incurred by Canaccord in connection with investigating

  
 -36- 

	 	
or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Prospectus or the Disclosure Package, or any such amendment or supplement thereto, in
reliance upon and in conformity with written information furnished to the Company by and through Canaccord expressly for use therein. 

  

	 	(b)	Canaccord Indemnification. Canaccord will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendments
thereto), the Prospectus (or any amendment or supplement thereto), the Disclosure Package or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact, in the case of the
Registration Statement or any amendment thereto, required to be stated therein or necessary to make the statements therein not misleading and, in the case of the Prospectus or any supplement thereto, the Disclosure Package or the Issuer Free Writing
Prospectus, necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was made in the Registration Statement (or any amendments thereto), the Prospectus (or any amendment or supplement thereto), the Disclosure Package, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with
written information furnished to the Company by and through Canaccord expressly for use therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such
action or claim as such expenses are incurred. 

  

	 	(c)	Procedure. 

  

	 	(i)	 Each indemnified party shall give written notice as promptly as reasonably practicable to each indemnifying party
of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially
prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this Section 10. In the case of parties indemnified pursuant to Section 10(a) above, counsel to the
indemnified parties shall be selected by Canaccord, and, in the case of parties indemnified pursuant to Section 10(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own
expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not 

  
 -37- 

	 	
(except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel
(in addition to any relevant local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations
or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 10 (whether or not the indemnified parties are actual or potential parties
thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a
statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. 

  

	 	(ii)	The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying
person agrees to indemnify each indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested that an indemnifying
party reimburse the indemnified party for reasonable fees and expenses of counsel as contemplated by this section, the indemnifying person shall be liable for any settlement of any proceeding effected without its written consent if (i) such
settlement is entered into (A) more than 60 days after receipt by the indemnifying party of such request and (B) more than 30 days after receipt by the indemnifying party of the proposed terms of such settlement and (ii) the
indemnifying party shall not have reimbursed the indemnified person in accordance with such request prior to the date of such settlement. 

  

	 	(d)	 Contribution. If the indemnification provided for in this Section 10 is unavailable to or
insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one
hand and Canaccord on the other from the offering of the Placement Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required
under subsection (c) above, then each indemnifying party shall 

  
 -38- 

	 	
contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on
the one hand and Canaccord on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The
relative benefits received by the Company on the one hand and Canaccord on the other shall be deemed to be in the same proportion as the total net proceeds from the offering of the Shares (before deducting expenses) received by the Company, bear to
the total underwriting discounts, commissions and other fees received by Canaccord. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company on the one hand or Canaccord on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement
or omission. The Company and Canaccord agree that it would not be just and equitable if contributions pursuant to this subsection (d) were determined by pro rata allocation or by any other method of allocation which does not take account of the
equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection
(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), Canaccord
shall not be required to contribute any amount in excess of the amount by which the total price at which the Placement Shares distributed to the public by it were offered to the public exceeds the amount of any damages which Canaccord has otherwise
been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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. 

  

	 	(e)	Obligations. The obligations of the Company under this Section 10 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and
conditions, to each person, if any, who controls Canaccord within the meaning of the Securities Act; and the obligations of Canaccord under this Section 10 shall be in addition to any liability which Canaccord may otherwise
have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Securities Act. 

11. Representations and Agreements to Survive Delivery. All representations and warranties of the Company herein or in certificates delivered pursuant
hereto shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of Canaccord, any controlling persons, or the Company (or any of their respective officers, directors or controlling persons),
(ii) delivery and acceptance of the Placement Shares and payment therefor or (iii) any termination of this Agreement. 

  
 -39- 

 12. Termination. 
  

	 	(a)	Canaccord shall have the right to terminate this Agreement at any time by giving notice as hereinafter specified if (i) any Material Adverse Effect has occurred, or any development that is reasonably expected to
cause a Material Adverse Effect has occurred or any other event has occurred which, in the sole judgment of Canaccord, may materially impair Canaccord’s ability to proceed with the offering to sell the Shares, (ii) the Company shall have
failed, refused or been unable, at or prior to any Settlement Date, to perform any agreement on its part to be performed hereunder, (iii) any other condition of Canaccord’s obligations hereunder is not fulfilled, or (iv) any
suspension or limitation of trading in the shares of Common Stock of the Company on the Principal Trading Market shall have occurred. Any such termination shall be without liability of any party to any other party except that the provisions of
Section 7(j) (Expenses), Section 10 (Indemnification), Section 11 (Survival of Representations), Section 12(f) (Termination),
Section 17 (Applicable Law; Consent to Jurisdiction) and Section 18 (Waiver of Jury Trial) hereof shall remain in full force and effect notwithstanding such termination. If Canaccord elects to
terminate this Agreement as provided in this Section 12(a), Canaccord shall provide the required notice as specified in Section 13 (Notices). 

 

	 	(b)	The Company shall have the right to terminate this Agreement in its sole discretion at any time by giving ten (10) days’ notice as hereinafter specified. Any such termination shall be without liability of any
party to any other party except that the provisions of Section 7(j), Section 10, Section 11, Section 12(f), Section 17
and Section 18 hereof shall remain in full force and effect notwithstanding such termination. 

  

	 	(c)	In addition to, and without limiting Canaccord’s rights under Section 12(a), Canaccord shall have the right to terminate this Agreement in its sole discretion at any time after the date of
this Agreement by giving ten (10) days’ notice as hereinafter specified. Any such termination shall be without liability of any party to any other party except that the provisions of Section 7(j),
Section 10, Section 11, Section 12(f), Section 17 and Section 18 hereof shall remain in full force and effect
notwithstanding such termination. 

  

	 	(d)	This Agreement shall remain in full force and effect unless terminated pursuant to Sections 12(a), 12(b) or 12(c) above or otherwise by mutual agreement of the parties; provided that any such
termination by mutual agreement shall in all cases be deemed to provide that Section 7(j), Section 10, Section 11, Section 12(f),
Section 17 and Section 18 shall remain in full force and effect. 

  
 -40- 

	 	(e)	Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that such termination shall not be effective until the close of business on the date of receipt of such
notice by Canaccord or the Company, as the case may be. If such termination shall occur prior to the Settlement Date for any sale of Placement Shares, such Placement Shares shall settle in accordance with the provisions of this Agreement.

  

	 	(f)	In the event that the Company terminates this Agreement, as permitted under Section 12(b), the Company shall be under no continuing obligation pursuant to this Agreement to utilize the services
of Canaccord in connection with any sale of securities of the Company or to pay any compensation to Canaccord other than compensation with respect to sales of Placement Shares subscribed on or before the termination date and the Company shall be
free to engage other placement agents and underwriters from and after the termination date with no continuing obligation to Canaccord.

remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. Neither party may assign its rights or obligations under this Agreement without the prior written consent of the other party,

one or more of the provisions contained herein, or the application thereof in any circumstance, is held invalid, illegal or unenforceable, the validity, legality and enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be affected or impaired thereby. 
 17. Applicable Law; Consent to Jurisdiction. This Agreement shall be
governed by, and construed in accordance with, the internal laws of the State of New York without regard to the principles of conflicts of laws. Each party hereby irrevocably submits to the non-exclusive
jurisdiction of the state and federal courts sitting in the City of New York, borough of Manhattan, for the adjudication of any dispute hereunder or in connection with any transaction contemplated hereby, and hereby irrevocably waives, and agrees
not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or
proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof (certified or registered mail, return receipt requested)
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. 

  
 -42- 

 18. Waiver of Jury Trial. The Company and Canaccord hereby irrevocably waive any right either may have to
a trial by jury in respect of any claim based upon or arising out of this Agreement or any transaction contemplated hereby. 
 19. Absence of Fiduciary
Duties. The parties acknowledge that they are sophisticated in business and financial matters and that each of them is solely responsible for making its own independent investigation and analysis of the transactions contemplated by this
Agreement. They further acknowledge that Canaccord has not been engaged by the Company to provide, and has not provided, financial advisory services in connection with the terms of the offering and sale of the Shares nor has Canaccord assumed at any
time a fiduciary relationship to the Company in connection with such offering and sale. The parties also acknowledge that the provisions of this Agreement fairly allocate the risks of the transactions contemplated hereby among them in light of their
respective knowledge of the Company and their respective abilities to investigate its affairs and business in order to assure that full and adequate disclosure has been made in the Registration Statement and the Prospectus (and any amendments and
supplements thereto). The Company hereby waives, to the fullest extent permitted by law, any claims it may have against Canaccord for breach of fiduciary duty or alleged breach of fiduciary duty and agrees Canaccord shall have no liability (whether
direct or indirect) to the Company in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of Company. 

20. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together
