Regulations”) of the Commission thereunder, and such amendments to such registration statement (including post effective amendments) as may have been required to the date of this Agreement and a preliminary prospectus supplement or
“red herring” pursuant to Rule 424(b) under the Securities Act. Such registration statement, as amended (including any post effective amendments) has been declared effective by the Commission. Such registration statement, including
amendments thereto (including post effective amendments thereto) at such time, the exhibits and any schedules thereto at such time and the documents and information otherwise deemed to be a part thereof or included therein by the Securities Act or
otherwise pursuant to the Rules and Regulations at such time, is herein called the “Registration Statement.” If the Company has filed or files an abbreviated registration statement pursuant to Rule 462(b) under the Securities Act

 The Company is filing with the Commission pursuant to Rule 424 under the Securities Act a final
prospectus supplement relating to the Shares to a form of prospectus included in the Registration Statement. The form of prospectus included in the Registration Statement at the time it was declared effective is hereinafter called the “Base

For purposes of this Agreement, all references to the Registration Statement, the Rule 462 Registration Statement, the Base Prospectus, the

2. Agreement to Act as Placement Agent; Placement of Shares. On the basis of the representations, warranties and agreements of
the Company herein contained, and subject to all the terms and conditions of this Agreement: 
 (a) The Company hereby
authorizes the Placement Agent to act as its exclusive agent to solicit offers for the purchase of all or part of the Shares from the Company in connection with the proposed offering of the Shares (the “Offering”). Until the Closing
Date (as defined in Section 4 below) or earlier upon termination of this Agreement pursuant to Section 9 the Company shall not, without the prior written consent of the Placement Agent, solicit or accept offers to purchase the Shares
otherwise than through the Placement Agent. 
 (b) The Company hereby acknowledges that the Placement Agent has agreed, as agent of the
Company, to use its commercially reasonable “best efforts” to solicit offers to purchase the Shares from the Company on the terms and subject to the conditions set forth in the Prospectus (as defined below). The Placement Agent shall use
commercially reasonable efforts to assist the Company in obtaining performance by each Purchaser whose offer to purchase Shares has been solicited by the Placement Agent and accepted by the Company, but the Placement Agent shall not, except as
otherwise provided in this Agreement, be obligated to disclose the identity of any potential purchaser or have any liability to the Company in the event any such purchase is not consummated for any reason. Under no circumstances will the Placement
Agent be obligated to underwrite or purchase any Shares for its own account and, in soliciting purchases of the Shares, the Placement Agent shall act solely as the Company’s agent and not as principal. 

(c) Subject to the provisions of this Section 2, offers for the purchase of the Shares may be solicited by the Placement Agent as agent
for the Company at such times and in such amounts as the Placement Agent deems advisable. The Placement Agent shall 

  
 2 

 
communicate to the Company, orally or in writing, each reasonable offer to purchase Shares received by it as agent of the Company. The Company shall have the sole right to accept offers to
purchase Shares and may reject any such offer, in whole or in part. 
 (d) The Shares are being sold to the Purchasers at an aggregate
initial public offering price of $1.72 per share (the “Public Offering Price”). The purchases of Shares by the Purchasers shall be evidenced by the execution of Subscription Agreements by each of the Purchasers and the Company. 

(e) As compensation for services rendered, on the Closing Date (as defined in Section 4 below), the Company shall pay to the Placement
Agent by wire transfer of immediately available funds to an account or accounts designated by the Placement Agent, an aggregate amount equal to six percent (6.0%) of the gross proceeds received by the Company (the “Placement
Fee”) from the sale of the Shares on the Closing Date. The Placement Agent may retain other brokers or dealers to act as sub-agents on its behalf in connection with the Offering, the fees of which shall be paid out of the Placement Fee.

 (f) No Shares which the Company has agreed to sell pursuant to this Agreement and the Subscription Agreements shall be deemed to have
been purchased and paid for, or sold by the Company, until such Shares shall have been delivered to the Purchaser thereof against payment by such Purchaser. If the Company shall default in its obligations to deliver Shares to a Purchaser whose offer
it has accepted, the Company shall indemnify and hold the Placement Agent harmless against any loss, claim, damage or expense arising from or as a result of such default by the Company in accordance with the procedures set forth in Section 7(c)
herein. 
 2a. Representations and Warranties of the Company Regarding the Offering. 

(a) The Company represents and warrants to, and agrees with, the Placement Agent, as of the date hereof and as of the Closing Date (as defined
in Section 4 below), except as otherwise indicated, as follows:

The representations and warranties set forth in the two

furnished to the Company by the Placement Agent specifically for use in the preparation thereof, which written information is described in Section 7(f). The Registration Statement contains all exhibits and schedules required to be filed by the
Securities Act or the Rules and Regulations. No order preventing or suspending the effectiveness or use of the Registration Statement or any Prospectus is in effect and no proceedings for such purpose have been instituted or are pending, or, to the

 (ii) The Company has not distributed any
prospectus or other offering material in connection with the offering and sale of the Shares other than the Time of Sale Disclosure Package and the Marketing Materials. 

(iii) (A) The Company has provided a copy to the Placement Agent of each Issuer Free Writing Prospectus (as defined below) used

no proceedings for such purpose have been instituted or are pending, or, to the knowledge of the Company, are contemplated or threatened by the Commission. When taken together with the rest of the Time of Sale Disclosure Package or the Final
Prospectus, since its first use and at all relevant times since then, no Issuer Free Writing Prospectus has, does or will include (1) any untrue statement of a material fact or omission to state any material fact necessary in
order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (2) information that conflicted, conflicts or will conflict with the information contained in the Registration Statement
or the Final Prospectus. The representations and warranties set forth in the immediately preceding sentence shall not apply to statements in or omissions from the Time of Sale Disclosure Package, the Final Prospectus or any Issuer Free Writing
Prospectus in reliance upon, and in conformity with, written information furnished to the Company by the Placement Agent specifically for use in the preparation thereof. As used in this paragraph and elsewhere in this Agreement: 

(1) “Time of Sale Disclosure Package” means the Base Prospectus, the Prospectus most recently filed with
the Commission before the time of this Agreement, including any preliminary prospectus supplement deemed to be a part thereof, each Issuer Free Writing Prospectus, and any description of the transaction provided by the Placement

(C) Each Issuer Free Writing Prospectus satisfied, as of its issue date and at all subsequent times through the Prospectus
Delivery Period, all other conditions as may be applicable to its use as set forth in Rules 164 and 433 under the Securities Act, including any legend, record-keeping or other requirements. 

(iv) The financial statements of the Company, together with the related notes, included or incorporated by reference in the

Company as of the dates indicated and the results of operations and changes in cash flows for the periods therein specified in conformity with generally accepted accounting principles consistently applied throughout the periods involved; and the
supporting schedules included in the Registration Statement, if any, present fairly the information required to be stated therein. No other financial statements, pro forma financial information or schedules are required under the Securities Act to
be included or incorporated by reference in the Registration Statement, the Time of Sale Disclosure Package or the Final Prospectus. To the Company’s knowledge, Grant Thornton LLP, which has expressed its opinion with respect to the financial
statements filed as a part of the Registration Statement and included in the Registration Statement, the Time of Sale Disclosure Package and the Final Prospectus is an independent public accounting firm with respect to the Company within the meaning

Final Prospectus or the Marketing Materials. 
 (vi) All statistical or market-related data included or incorporated by
reference in the Registration Statement, the Time of Sale Disclosure Package or the Final Prospectus, or included in the Marketing Materials, are based on or derived from sources that the Company reasonably believes to be reliable and accurate, and
the Company has obtained the written consent to the use of such data from such sources, to the extent required. 
 (vii) The

 (viii) The Company has not taken, directly or indirectly, any action that is
designed to or that has constituted or that would reasonably be expected to cause or result in the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Shares. 

(ix) The Company is not and, after giving effect to the offering and sale of the Shares and the application of the net proceeds
thereof, will not be an “investment company,” as such term is defined in the Investment Company Act of 1940, as amended. 
 (b)
Any certificate signed by any officer of the Company and delivered to the Placement Agent or to the Placement Agent’s counsel shall be deemed a representation and warranty by the Company to the Placement Agent as to the matters covered thereby.

authority performing functions similar to those performed by the FDA) required for the conduct of its business, and all such Permits are in full force and effect, in each case except where the failure to hold, or comply with, any of them is not
reasonably likely to result in a Material Adverse Effect. 

  
 8 

 (xi) The Company and its subsidiaries have good and marketable title to all
property (whether real or personal) described in the Registration Statement, the Time of Sale Disclosure Package and the Prospectus as being owned by them that are material to the business of the Company, in each case free and clear of all liens,

deficiencies have been asserted by any applicable regulatory authority (including, without limitation, the FDA or any foreign, federal, state or local governmental or regulatory authority performing functions similar to those performed by the FDA)
with respect to any such filings, declarations, listings, registrations, reports or submissions. 
 (xvii) Neither the
Company nor any of its subsidiaries nor, to the knowledge of the Company, any director, officer, employee, representative, agent or affiliate of the Company or any of its subsidiaries is currently subject to any U.S. sanctions administered by the
Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”); and the Company will not directly or indirectly use the proceeds of the offering of the Shares contemplated hereby, or lend, contribute or otherwise make

 5. Covenants. 

(a) The Company covenants and agrees with the Placement Agent as follows: 

(i) During the period beginning on the date hereof and ending on the later of the Closing Date or such date as determined by
the Placement Agent that the Prospectus is no longer required by law to be delivered in connection with sales by an underwriter or dealer (such period, the “Prospectus Delivery Period”), prior to amending or supplementing the
Registration Statement, including any Rule 462 Registration Statement, the Time of Sale Disclosure Package or the Prospectus, the Company shall furnish to the Placement Agent for review and comment a copy of each such proposed amendment or
supplement, and the Company shall not file any such proposed amendment or supplement to which the Placement Agent reasonably objects. 

(ii) From the date of this Agreement until the end of the Prospectus Delivery Period, the Company shall promptly advise the
Placement Agent in writing (A) of the receipt of any comments of, or requests for additional or supplemental information from, the Commission, (B) of the time and date of any filing of any post-effective amendment to the Registration
Statement or any amendment or supplement to the Time of Sale Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus, (C) of the time and date that any post-effective amendment to the Registration Statement becomes effective
and (D) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending its use or the use of the Time of Sale Disclosure Package or any Issuer Free Writing
Prospectus, or of any proceedings to remove, suspend or terminate from listing or quotation the Common Stock from any securities exchange upon which it is listed for trading or included or designated for quotation, or of the threatening or
initiation of any proceedings for any of such purposes. If the Commission shall enter any such stop order at any time during the Prospectus Delivery Period, the Company will use its reasonable efforts to obtain the lifting of such order at the
earliest possible moment. Additionally, the Company agrees that it shall comply with the provisions of Rules 424(b), 430A and 430B, as applicable, under the Securities Act and will use its reasonable efforts to confirm that any filings made by the
Company under Rule 424(b) or Rule 433 were received in a timely manner by the Commission (without reliance on Rule 424(b)(8) or 164(b) of the Securities Act). 

(iii) (A) During the Prospectus Delivery Period, the Company will comply with all requirements imposed upon it by the
Securities Act, as now and hereafter 

  
 12 

 
amended, and by the Rules and Regulations, as from time to time in force, and by the Exchange Act, as now and hereafter amended, so far as necessary to permit the continuance of sales of or
dealings in the Shares as contemplated by the provisions hereof, the Time of Sale Disclosure Package, the Registration Statement and the Prospectus. If during such period any event occurs the result of which the Prospectus (or if the Prospectus is
not yet available to prospective purchasers, the Time of Sale Disclosure Package ) would include an untrue statement of a 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 or appropriate in the opinion of the Company or its counsel or the Placement Agent or its counsel to amend the Registration Statement or supplement the Prospectus (or if the
Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package ) to comply with the Securities Act, the Company will promptly notify the Placement Agent, allow the Placement Agent the opportunity to provide reasonable
comments on such amendment, Prospectus supplement or document, and will amend the Registration Statement or supplement the Prospectus (or if the Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package) so as to
correct such statement or omission or effect such compliance. 
 (B) If at any time following the issuance of an Issuer Free
Writing Prospectus there occurred or occurs an event or development the result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement or any Prospectus or included or
would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the
Company has promptly notified or promptly will notify the Placement Agent and has promptly amended or will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement
or omission. 
 (iv) The Company shall take or cause to be taken all necessary action to qualify the Shares for sale under
the securities laws of such jurisdictions as the Placement Agent reasonably designates and to continue such qualifications in effect so long as required for the distribution thereof, except that the Company shall not be required in connection
therewith to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified, to execute a general consent to service of process in any state or to subject itself to taxation in respect of doing
business in any jurisdiction in which it is not otherwise subject. 
 (v) The Company will furnish to the Placement Agent and
counsel for the Placement Agent copies of the Registration Statement, each Prospectus, any Issuer Free Writing Prospectus, and all amendments and supplements to such documents, in each case as soon as available and in such quantities as the
Placement Agent may from time to time reasonably request. 
 (vi) The Company will make generally available to its security
holders as soon as practicable, but in any event not later than 15 months after the end of the 

  
 13 

 
Company’s current fiscal quarter, an earnings statement (which need not be audited) covering a 12-month period that shall satisfy the provisions of Section 11(a) of the Securities Act
and Rule 158 of the Rules and Regulations. 
 (vii) The Company, whether or not the transactions contemplated hereunder are
consummated or this Agreement is terminated, will pay or cause to be paid (A) all expenses (including transfer taxes allocated to the respective transferees) incurred in connection with the delivery to the Placement Agent of the Shares,
(B) all expenses and fees (including, without limitation, fees and expenses of the Company’s counsel) in connection with the preparation, printing, filing, delivery, and shipping of the Registration Statement (including the financial
statements therein and all amendments, schedules, and exhibits thereto), the Shares, the Time of Sale Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus and any amendment thereof or supplement thereto, (C) all reasonable
filing fees and reasonable fees and disbursements of the Placement Agent’s counsel incurred in connection with the qualification of the Shares for offering and sale by the Placement Agent or by dealers under the securities or blue sky laws of
the states and other jurisdictions that the Placement Agent shall designate, (D) the fees and expenses of any transfer agent or registrar for the Common Stock, (E) the reasonable filing fees and reasonable fees and disbursements of
Placement Agent’s counsel incident to any required review and approval by FINRA of the terms of the sale of the Shares, (F) listing fees, if any, and (G) all other costs and expenses incurred by it incident to the performance of its
obligations hereunder that are not otherwise specifically provided for herein. In addition to the foregoing, the Company will reimburse the Placement Agent for its reasonable out-of-pocket expenses, including the fees and disbursement’s of its
counsel, incurred in connection with the purchase and sale of the Shares contemplated hereby provided, however, that out-of-pocket and legal expenses exceeding $35,000 in the aggregate shall require prior approval of the Company, such approval not
to be unreasonably withheld. In no event may the maximum compensation payable to FINRA members and independent broker-dealers exceed 8.0% of the gross proceeds of this offering. If this Agreement is terminated by the Placement Agent in accordance
with the provisions of Section 6 or Section 9, the Company will reimburse the Placement Agent for all out-of-pocket disbursements (including, but not limited to, reasonable fees and disbursements of counsel, travel expenses, postage,
facsimile and telephone charges) actually incurred by the Placement Agent in connection with its investigation, preparing to market and marketing the Shares or in contemplation of performing its obligations hereunder. 

(viii) The Company intends to apply the net proceeds from the sale of the Shares to be sold by it hereunder for the purposes
set forth in the Time of Sale Disclosure Package and in the Final Prospectus. 
 (ix) The Company has not taken and will not
take, directly or indirectly, during the Prospectus Delivery Period, any action designed to or which might reasonably be expected to cause or result in, or that has constituted, the stabilization or manipulation of the price of any security of the
Company to facilitate the sale or resale of the Shares. 

  
 14 

 (x) The Company represents and agrees that, unless it obtains the prior written
consent of the Placement Agent, and the Placement Agent represents and agrees that, unless it obtains the prior written consent of the Company, it has not made and will not make any offer relating to the Shares that would constitute an Issuer Free
Writing Prospectus; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the free writing prospectuses included in Schedule I. Any such free writing prospectus consented to by the
Company and the Placement Agent is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated or agrees that it will treat each Permitted Free Writing Prospectus as an “issuer
free writing prospectus,” as defined in Rule 433, and has complied or will comply with the requirements of Rule 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and
record-keeping. 
 (xi) The Company hereby agrees that, without the prior written consent of the Placement Agent, it will
not, during the period ending 60 days after the date hereof (“Lock-Up Period”), (i) offer, pledge, issue, sell, contract to sell, purchase, contract to purchase, lend, or otherwise transfer or dispose of, directly or
indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock; or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic
consequences of ownership of the Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise; or (iii) file any
registration statement with the Commission relating to the offering of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock. The restrictions contained in the preceding sentence shall not
apply to (1) the Shares to be sold hereunder, (2) the issuance of Common Stock upon the exercise of options or warrants disclosed as outstanding in the Registration Statement (excluding exhibits thereto), the Time of Sale Disclosure
Package or the Prospectus, or (3) the issuance of employee stock options not exercisable during the Lock-Up Period and the grant of restricted stock awards or restricted stock units pursuant to equity incentive plans described in the
Registration Statement (excluding exhibits thereto), the Time of Sale Disclosure Package and the Prospectus. Notwithstanding the foregoing, if (x) the Company issues an earnings release or material news, or a material event relating to the
Company occurs, during the last 17 days of the Lock-Up Period, or (y) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up
Period, the restrictions imposed by this clause shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event, unless the Placement Agent
waives such extension in writing.

7. Indemnification and Contribution. 

(a) The Company agrees to indemnify, defend and hold harmless the Placement Agent, its affiliates, directors and officers and employees, and
each person, if any, who controls the Placement Agent within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any losses, claims, damages or liabilities to which the Placement Agent or
such person may become subject, under the Securities Act or otherwise (including in settlement of any litigation if such settlement is effected with the written consent of the Company), insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, including the information deemed to

  
 17 

 
be a part of the Registration Statement at the time of effectiveness and at any subsequent time pursuant to Rules 430A and 430B of the Rules and Regulations, or arise out of or are based upon the
omission from the Registration Statement, or alleged omission to state therein, a material fact required to be stated therein or necessary to make the statements therein not misleading (ii) an untrue statement or alleged untrue statement of a
material fact contained in the Time of Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto (including any documents filed under the Exchange Act and deemed to be incorporated by reference into the Registration Statement
or the Prospectus), any Issuer Free Writing Prospectus or the Marketing Materials or in any other materials used in connection with the offering of the Shares, or arise out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, (iii) in whole or in part, any inaccuracy in the representations and warranties
of the Company contained herein or in the Subscription Agreements, or (iv) in whole or in part, any failure of the Company to perform its obligations hereunder, under the Subscription Agreements or under law, and will reimburse the Placement
Agent for any legal or other expenses reasonably incurred by it in connection with evaluating, investigating or defending against such loss, claim, damage, liability or action; provided, however, that the Company shall not be liable in any
such case to the extent that any such loss, claim, damage, liability or action 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 Time of Sale
Disclosure Package, the Prospectus, or any amendment or supplement thereto or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company by the Placement Agent specifically for use in the
preparation thereof, which written information is described in Section 7(f). 
 (b) The Placement Agent will indemnify, defend and hold
harmless the Company, its affiliates, directors, officers and employees, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any
losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Placement Agent),
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 Time of Sale
Disclosure Package, the Prospectus, or any amendment or supplement thereto 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 required to be stated therein or
necessary to make the statements therein 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, the Time of
Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto or any Issuer Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Company by the Placement Agent specifically for use in
the preparation thereof, and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with defending against any such loss, claim, damage, liability or action. 

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action,
such indemnified party shall, if a claim in 

  
 18 

 
respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the failure to notify the
indemnifying party shall not relieve the indemnifying party from any liability that it may have to any indemnified party except to the extent such indemnifying party has been materially prejudiced by such failure. In case any such action shall be
brought against any indemnified party, and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in, and, to the extent that it shall wish, jointly with any other indemnifying
party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of the indemnifying party’s election so to assume the defense
thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof; provided,
however, that if (i) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to
the indemnifying party, (ii) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to
direct the defense of such action on behalf of the indemnified party), or (iii) the indemnifying party has not in fact employed counsel reasonably satisfactory to the indemnified party to assume the defense of such action within a reasonable
time after receiving notice of the commencement of the action, the indemnified party shall have the right to employ a single counsel to represent it in any claim in respect of which indemnity may be sought under subsection (a) or (b) of
this Section 7, in which event the reasonable fees and expenses of such separate counsel shall be borne by the indemnifying party or parties and reimbursed to the indemnified party as incurred. 

The indemnifying party under this Section 7 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 party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or
judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any
indemnified party is a party or could be named and indemnity was or would be sought hereunder by such indemnified party, unless such settlement, compromise or consent (a) includes an unconditional release of such indemnified party from all
liability for claims that are the subject matter of such action, suit or proceeding and (b) 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. 

(d) If the indemnification provided for in this Section 7 is unavailable or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or
(b) above, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Placement Agent on the other from the offering and sale of the Shares or (ii) if the allocation
provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the 

  
 19 

 
relative fault of the Company on the one hand and the Placement Agent on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as
well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Placement Agent on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before
deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Placement Agent, in each case as set forth in the table on the cover page of the Final Prospectus. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Placement Agent and
the parties’ relevant intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Placement Agent agree that it would not be just and equitable if contributions pursuant
to this subsection (d) were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the first sentence of this subsection (d). The amount paid by an
indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of 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 against any action or claim that is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), the Placement Agent shall not be required to contribute any amount in excess of
the amount of the Placement Agent’s commissions actually received by the Placement Agent pursuant to this Agreement. 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) The obligations of the Company
under this Section 7 shall be in addition to any liability that the Company may otherwise have and the benefits of such obligations shall extend, upon the same terms and conditions, to each person, if any, who controls the Placement Agent
within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act; and the obligations of the Placement Agent under this Section 7 shall be in addition to any liability that the Placement Agent may otherwise
have and the benefits of such obligations shall extend, upon the same terms and conditions, to the Company, and its officers, directors and each person who controls the Company within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act. 
 (f) For purposes of this Agreement, the Placement Agent confirms, and the Company acknowledges, that
there is no information concerning the Placement Agent furnished in writing to the Company by the Placement Agent specifically for preparation of or inclusion in the Registration Statement, the Time of Sale Disclosure Package, the Prospectus or any
Issuer Free Writing Prospectus, other than the statements set forth on the cover page of the Prospectus and in the “Underwriting” section of the Prospectus and Time of Sale Disclosure Package, in each case only insofar as such statements
relate to the amount of selling concession and re-allowance or to over-allotment, price stabilization, electronic distribution and related activities that may be undertaken by the Placement Agent. 

8. Representations and Agreements to Survive Delivery. All representations, warranties, and agreements of the Company herein or
in certificates delivered pursuant hereto, 

  
 20 

 
including, but not limited to, the agreements of the Placement Agent and the Company contained in Section 5(a)(vii) and Section 7 hereof, shall remain operative and in full force and
effect regardless of any investigation made by or on behalf of the Placement Agent or any controlling person thereof, or the Company or any of its officers, directors, or controlling persons, and shall survive delivery of, and payment for, the
Shares to and by the Placement Agent hereunder. 
 9. Termination of this Agreement. 

(a) The Placement Agent shall have the right to terminate this Agreement and the obligations of the Purchasers hereunder and under the
Subscription Agreements by giving notice to the Company as hereinafter specified at any time at or prior to the Closing Date, if in the discretion of the Placement Agent, (i) there has occurred any material adverse change in the securities
markets or any event, act or occurrence that has materially disrupted, or in the opinion of the Placement Agent, will in the future materially disrupt, the securities markets or there shall be such a material adverse change in general financial,
political or economic conditions or the effect of international conditions on the financial markets in the United States is such as to make it, in the judgment of the Placement Agent, inadvisable or impracticable to market the Shares or enforce
contracts for the sale of the Shares, (ii) trading in the Company’s Common Stock shall have been suspended by the Commission or the NASDAQ Capital Market or trading in securities generally on the NASDAQ Stock Market, the New York Stock
Exchange or NYSE MKT shall have been suspended, (iii) minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, on any Nasdaq Stock Market, the New York Stock Exchange or
NYSE MKT, by such exchange or by order of the Commission or any other governmental authority having jurisdiction, (iv) a banking moratorium shall have been declared by federal or state authorities, (v) there shall have occurred any attack
on, outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration by the United States of a national emergency or war, any substantial change or development involving a prospective substantial change in
United States or international political, financial or economic conditions or any other calamity or crisis, (vi) the Company suffers any loss by strike, fire, flood, earthquake, accident or other calamity, whether or not covered by insurance,
(vii) in the judgment of the Placement Agent, there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus, any material adverse change in the assets, properties,
condition, financial or otherwise, or in the results of operations, business affairs or business prospects of the Company and its subsidiaries considered as a whole, whether or not arising in the ordinary course of business, or (viii) the
Purchasers shall decline to purchase the Shares for any reason permitted under this Agreement or the Subscription Agreements. Any such termination shall be without liability of any party to any other party except that the provisions of
Section 5(a)(vii) and Section 7 hereof shall at all times be effective and shall survive such termination. 
 (b) If the Placement
Agent elects to terminate this Agreement as provided in this Section, the Company shall be notified promptly by the Placement Agent by telephone, confirmed by letter.

solely to act as Placement Agent in connection with the sale of the Shares and that no fiduciary, advisory or agency relationship between the Company and the Placement Agent has been created in respect of any of the transactions contemplated by this
