Raymond James & Associates, Inc.

277 Park Avenue, Suite 410

New York, New York 10172

Ladies and Gentlemen:

 

PLx Pharma Inc.,
a Delaware corporation (the “Company”), proposes, subject to the terms and conditions of this Placement
Agency Agreement (the “Agreement”) and the Purchase Agreement (defined below), to issue and sell to
certain investors (each, a “Purchaser” and collectively, the “Purchasers”) (i) up to an
aggregate of 4,755,373 shares (the “Shares”) of the Company’s common stock, par value $0.001 per
share (the “Common Stock”), and (ii) warrants (the “Warrants”) to purchase up to an
additional  5,230,910 shares of Common Stock. The shares of Common Stock issuable upon exercise of the Warrants are referred
to herein as the “Warrant Shares.” The Shares, the Warrants and the Warrant Shares are referred to herein,
collectively, as the “Securities.” The Company desires to engage Raymond James & Associates, Inc. as
the exclusive placement agent in connection with such issuance and sale of the Securities.

 

The Company hereby
confirms its agreement with you as follows:

 

Section 1.              
Agreement to Act as Placement Agent.

 

(a)              
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, Raymond James & Associates, Inc. shall be the Company’s exclusive placement agent (in
such capacity, the “Placement Agent”), acting on a reasonable efforts basis, in connection with the issuance
and sale by the Company of the Securities to the Purchasers in a private placement exempt from registration under the Securities
Act of 1933, as amended (the “Securities Act”), pursuant to Section 4(a)(2) thereof, with the terms of the offering
to be subject to market conditions and negotiations among the Company, the Placement Agent and the prospective Purchasers (such
offering shall be referred to herein as the “Offering”). As compensation for services rendered, and provided
that any of the Securities are sold to Purchasers in the Offering, on the Closing Date (as defined in Section 1(c) hereof)
of the Offering, the Company shall pay to the Placement Agent an amount in the aggregate equal to 6% of the gross proceeds received
by the Company from the sale of the Shares and Warrants (the “Placement Fee”). The Placement Agent will not
receive any fees in connection with the exercise of the Warrants. The sale of the Securities shall be made pursuant to the purchase
agreement in the form included as Exhibit A hereto (the “Purchase Agreement”) on the terms described
therein. The Company shall have the sole right to accept offers to purchase the Securities and may reject any such offer in whole
or in part.

 

     

     

    

 

(b)              
This Agreement shall not give rise to any commitment by the Placement Agent to purchase any of the Securities, and the Placement
Agent shall have no authority to bind the Company to accept offers to purchase the Securities. The Placement Agent shall act on
a reasonable efforts basis and does not guarantee that it will be able to raise new capital in the Offering. 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. Prior to the earlier of (i) the date on which this Agreement is terminated and (ii) the Closing
Date, the Company shall not, without the prior written consent of the Placement Agent, solicit or accept offers to purchase Securities
(other than pursuant to the exercise of options or warrants to purchase Common Stock that are outstanding at the date hereof) otherwise
than through the Placement Agent in accordance herewith.

 

(c)              
Payment of the purchase price for, and delivery of, the Securities shall be made at a closing (the “Closing”)
at the offices of Olshan Frome Wolosky LLP, counsel for the Company, located at 1325 Avenue of the Americas, New York, NY 10019,
promptly following the satisfaction of all conditions for Closing set forth in the Purchase Agreement (the “Closing Conditions”)
or on such later date or at such different location as the parties shall agree in writing, but not prior to or later than the third
Business Day (as defined herein) after, the date that the Closing Conditions have been satisfied or waived by the appropriate party
(such date of payment and delivery being herein called the “Closing Date”). All such actions taken at the Closing
shall be deemed to have occurred simultaneously. No Shares and Warrants which the Company has agreed to sell pursuant to this Agreement
and the Purchase Agreement shall be deemed to have been purchased and paid for, or sold by the Company, until such Shares and Warrants
shall have been delivered to the Purchaser thereof against payment therefor by such Purchaser. If the Company shall default in
its obligations to deliver the Shares and Warrants to a Purchaser whose offer it has accepted, the Company shall indemnify and
hold the Placement Agent harmless against any loss, claim or damage incurred by the Placement Agent arising from or as a result
of such default by the Company. “Business Day” shall mean any day other than a Saturday, a Sunday or a legal
holiday or a day on which banking institutions or trust companies are authorized or obligated by law to close in New York City.

 

(d)              
On the Closing Date and on each closing date of the purchase and sale of Warrant Shares, (i) the Company shall deliver,
or cause to be delivered, the Securities to the Purchasers or their designees, and the Purchasers shall deliver, or cause to be
delivered, the purchase price for their respective Securities to the Company pursuant to the terms of the Purchase Agreement and
(ii) the Company will wire the amounts owed to the Placement Agent as provided in this Agreement.

 

(e)              
The Securities shall be registered in such names and in such denominations as the Placement Agent shall request by written
notice to the Company.

 

(f)               
The Securities shall bear an appropriate restrictive legend referring to the fact that the Securities were sold in reliance
upon the exemption from registration under the Securities Act provided by Section 4(a)(2) thereof. At such time as the registration
statement filed by the Company pursuant to the Purchase Agreement (the “Resale Registration Statement”) becomes
effective, the Company shall deliver to the Company’s transfer agent written instructions in proper form to the effect that,
notwithstanding any legend that is set forth in any certificate or certificates representing any of the Securities being purchased
pursuant to the Purchase Agreement, the Company’s transfer agent can implement and effect any proposed sale by the Purchasers
of any of such Securities if such proposed sale is under the Resale Registration Statement and is accompanied by a separate certificate
of subsequent sale from the applicable Purchaser in the form prescribed under the Purchase Agreement certifying that (i) the Securities
are being sold in accordance with the Resale Registration Statement, the Securities Act and applicable state securities or Blue
Sky laws and (ii) the prospectus delivery requirements under the Securities Act have been satisfied.

in the reports, schedules, forms, statements and other documents filed by the Company under the Securities Exchange Act of 1934,
as amended (the “Exchange Act”) (the foregoing materials, including the exhibits thereto and documents incorporated
by reference therein, and any amendment filed in relation thereto, being collectively referred to herein as the “SEC Reports”),

is a direct or indirect wholly owned subsidiary of the Company. Each Subsidiary is duly organized, validly existing and in good
standing under the laws of its jurisdiction of incorporation and is qualified to do business as a foreign corporation in each jurisdiction

are fully paid and nonassessable, have been issued in compliance with all federal and state securities laws, were not issued
in violation of or subject to any preemptive rights or other rights to subscribe for or purchase securities, and conform in
all material respects to the description contained in the SEC Reports. The Subsidiaries do not have outstanding any options
to purchase, or any preemptive rights or other rights to subscribe for or to purchase, any securities or obligations

Agreement have been duly authorized and, when issued, delivered and paid for in the manner set forth in the Purchase Agreement,
and with respect to the Warrant Shares, upon payment of the exercise price pursuant to the terms of the Warrants, will be validly
issued, fully paid and nonassessable. The Warrant Shares have been duly and validly reserved from the Company’s authorized
capital stock. No stockholder of the Company has any right to require the Company to register the sale of any capital stock owned
by such stockholder under the Resale Registration Statement. No further approval or authority of the stockholders or the Board
of Directors of the Company will be required for the issuance and sale of the Shares and the Warrants to be sold by the Company
as contemplated in the Purchase Agreement.

such laws. The execution and performance of this Agreement and the Purchase Agreement by the Company and the consummation of the
transactions herein and therein contemplated will not violate any provision of the certificate of incorporation or bylaws of the
Company or the organizational documents of any Subsidiary and will not result in the creation of any lien, charge, security interest

or any Subsidiary is a party or by which the Company or any Subsidiary or their respective properties may be bound or affected
and in each case that would have a Material Adverse Effect or any statute or any authorization, judgment, decree, order, rule or
regulation of any court or any regulatory body, administrative agency or other governmental agency or body applicable to the Company
or any Subsidiary or any of their respective properties. No consent, approval, authorization or other order of any court, regulatory
body, administrative agency or other governmental agency or body is required for the execution and delivery of this Agreement,
the Purchase Agreement or the consummation of the transactions contemplated herein and therein, except for compliance with the
Blue Sky laws and federal securities laws applicable to the offering of the Shares and the Warrants. For the purposes of this Agreement,

following, either alone or in combination, shall not be deemed a Material Adverse Effect: (i) effects caused by changes or circumstances

No Defaults or Consents. Neither the execution, delivery and performance of this Agreement or any Purchase Agreement
by the Company nor the consummation of any of the transactions contemplated hereby or thereby (including, without limitation, the
issuance and sale by the Company of the Shares and the Warrants) will give rise to a right to terminate or accelerate the due date
of any payment due under, or conflict with or result in the breach of any term or provision of, or constitute a default (or an
event which with notice or lapse of time or both would constitute a default) under, except such defaults that individually or in
the aggregate would not cause a Material Adverse Effect, or require any consent or waiver under, or result in the execution or
imposition of any lien, charge or encumbrance upon any properties or assets of the Company or its Subsidiaries pursuant to the
terms of, any indenture, mortgage, deed of trust or other agreement or instrument to which the Company or any of its Subsidiaries
is a party or by which either the Company or its Subsidiaries or any of its or their properties or businesses is bound, or any

the Company nor any Subsidiary has received any notice of proceedings relating to the revocation or modification of any such permit
that, if the subject of an unfavorable decision, ruling or finding, could reasonably be expected to have a Material Adverse Effect.

 

     

     

    

 

(v)              
Financial Statements. The financial statements of the Company, and the related notes and schedules thereto, included
in the SEC Reports fairly present in all material respects the financial position, results of operations, stockholders’ equity
and cash flows of the Company at the dates and for the periods specified therein. Such financial statements and the related notes
and schedules thereto have been prepared in accordance with generally accepted accounting principles consistently applied throughout
the periods involved (except as otherwise noted therein) and all adjustments necessary for a fair presentation in all material
respects of results for such periods have been made; provided, however, that the unaudited financial statements are
subject to normal year-end audit adjustments (which are not expected to be material) and do not contain all footnotes required
under generally accepted accounting principles.

 

(w)            
Listing Compliance. The Company complies with all requirements of the NASDAQ Capital Market and shall cause the Shares
and the Warrant Shares to be approved for listing on the NASDAQ Capital Market on the Closing Date.

 

(x)              
Internal Accounting Controls. The Company and each Subsidiary maintains a system of internal accounting controls
sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or
specific authorization; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity
with generally accepted accounting principles and to maintain accountability for assets; (iii) access to assets is permitted only
in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared
with existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company and each
Subsidiary has disclosure controls and procedures (as defined in Rules 13a-14 and 15d-14 under the Exchange Act) that are designed
to ensure that material information relating to such entity is made known to such entity’s principal executive officer and
principal financial officer or persons performing similar functions. The Company and each Subsidiary is otherwise in compliance
in all material respects with all applicable provisions of the Sarbanes-Oxley Act of 2002, as amended, and the rules and regulations
promulgated thereunder.

 

(y)              
Foreign Corrupt Practices. Neither the Company, nor any Subsidiary, nor, to the Company’s knowledge, any director,
officer, agent, employee or other persons acting on behalf of the Company or any Subsidiary has, in the course of its actions for,
or on behalf of, the Company (i) used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful
expenses relating to political activity; (ii) made any direct or indirect unlawful payment to any foreign or domestic government
official or employee from corporate funds; (iii) violated or is in violation of any provision of the U.S. Foreign Corrupt Practices
Act of 1977, as amended; or (iv) made any unlawful bribe, rebate, payoff, influence payment, kickback or other unlawful payment
to any foreign or domestic government official or employee.

 

(z)              
OFAC. Neither the Company nor any Subsidiary nor, to the Company’s knowledge, any director, officer, agent,
employee, affiliate or person acting on behalf of the Company or any Subsidiary 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 knowingly,
directly or indirectly, use the proceeds of the sale of the Shares and the Warrants, or lend, contribute or otherwise make available
such proceeds to any Subsidiary, joint venture partner or other person or entity, towards any sales or operations in any country
sanctioned by OFAC or for the purpose of financing the activities of any person currently subject to any U.S. sanctions administered
by OFAC.

 

     

     

    

 

(aa)           
Money Laundering Laws. The operations of the Company and each Subsidiary are and have been conducted at all times
in material compliance with the money laundering statutes of applicable jurisdictions, the rules and regulations thereunder and
any related or similar rules, regulations or guidelines, issued, administered or enforced by any applicable governmental agency
(collectively, the “Money Laundering Laws”) and to the Company’s and its Subsidiary’s knowledge,
no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the
Company and/or any Subsidiary with respect to the Money Laundering Laws is pending or threatened.

 

(bb)          
Employee Relations. Neither the Company nor any Subsidiary is a party to any collective bargaining agreement or employs
any member of a union. The Company and each Subsidiary believes that their relations with their employees are good. No executive
officer of the Company (as defined in Rule 501(f) promulgated under the Securities Act) has notified the Company, as applicable,
that such officer intends to leave the Company or any Subsidiary, as applicable, or otherwise terminate such officer’s employment
with the Company or any Subsidiary, as applicable. To the knowledge of the Company, no executive officer of the Company or any
Subsidiaries is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure
or proprietary information agreement, non-competition agreement, or any other agreement or any restrictive covenant, and the continued
employment of each such executive officer does not subject the Company or any Subsidiary to any liability with respect to any of
the foregoing matters.

 

(cc)           
ERISA. The Company and each Subsidiary is in compliance in all material respects with all presently applicable provisions
of the Employee Retirement Income Security Act of 1974, as amended, including the regulations and published interpretations thereunder
(herein called “ERISA”); no “reportable event” (as defined in ERISA) has occurred with respect to
any “pension plan” (as defined in ERISA) for which the Company or its Subsidiaries would have any liability; neither
the Company nor its Subsidiaries have incurred and do not expect to incur liability under (i) Title IV of ERISA with respect to
termination of, or withdrawal from, any “pension plan”; or (ii) Sections 412 or 4971 of the Internal Revenue Code of
1986, as amended, including the regulations and published interpretations thereunder (the “Code”); and each
“Pension Plan” for which the Company or its Subsidiaries would have liability that is intended to be qualified under
Section 401(a) of the Code is so qualified in all material respects and nothing has occurred, whether by action or by failure to
act, which would cause the loss of such qualification.

 

(dd)          Environmental
Matters. There has been no storage, disposal, generation, manufacture, transportation, handling or treatment of toxic wastes,
hazardous wastes or hazardous substances by the Company or any Subsidiary (or, to the knowledge of the Company, any of their predecessors
in interest) at, upon or from any of the property now or previously owned or leased by the Company or any Subsidiary in violation
in any material respect of any applicable law, ordinance, rule, regulation, order, judgment, decree or permit or that would require
material remedial action under any applicable law, ordinance, rule, regulation, order, judgment, decree or permit; there has been
no material spill, discharge, leak, emission, injection, escape, dumping or release of any kind into such property or into the
environment surrounding such property of any toxic wastes, medical wastes, solid wastes, hazardous wastes or hazardous substances
due to or caused by the Company or any Subsidiary or with respect to which the Company or any Subsidiary have knowledge; the terms
“hazardous wastes,” “toxic wastes,” “hazardous substances” and “medical wastes”
shall have the meanings specified in any applicable local, state, federal and foreign laws or regulations with respect to environmental
protection.

 

     

     

    

 

(ee)           
Integration; Other Issuances of Securities. Neither the Company nor its Subsidiaries or any affiliates, nor any persons
acting on its or their behalf, has issued any shares of Common Stock or shares of any series of preferred stock or other securities
or instruments convertible into, exchangeable for or otherwise entitling the holder thereof to acquire shares of Common Stock which
would be integrated with the sale of the Shares and the Warrants to the Purchasers pursuant to the Purchase Agreement (i) for purposes
of the Securities Act and would thereby result in the Shares and the Warrants being sold to the Purchasers pursuant to the Purchase
Agreement not to be exempt from the registration requirements of the Securities Act or (ii) for purposes of any applicable stockholder
approval provisions, including, without limitation, under the rules and regulations of any exchange or automated quotation system
on which any of the securities of the Company are listed or designated, nor will the Company or its Subsidiaries or affiliates
take any action or steps that would require registration of any of the Shares or the Warrants under the Securities Act or cause
the offering of the Shares and the Warrants to be integrated with other offerings. Assuming the accuracy of the representations
and warranties of Purchasers, the offer and sale of the Shares and the Warrants by the Company to the Purchasers pursuant to the
Purchase Agreement will be exempt from the registration requirements of the Securities Act.

 

Section 3.              
Covenants.

 

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

 

(a)              
Use of Proceeds. The Company shall use the net proceeds from the sale of the Shares and the Warrants to continue
to advance its clinical programs and for working capital and general corporate purposes.

 

(b)              
Lock-Up Period. For a period of 90 days after the date hereof (the “Lock-Up Period”), the Company
will not directly or indirectly, (1) offer to sell, hypothecate, pledge, announce the intention to sell, contract to sell, or otherwise
transfer or dispose of, directly or indirectly, any shares of Common Stock, or any securities convertible into or exercisable or
exchangeable for shares of Common Stock; (2) except for the Resale Registration Statement, file or cause to become effective a
registration statement under the Securities Act relating to the offer and sale of any shares of Common Stock or securities convertible
into or exercisable or exchangeable for shares of Common Stock; or (3) enter into any swap or other agreement that transfers, in
whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in
clauses (1), (2) or (3) above is to be settled by delivery of shares of Common Stock or such other securities, in cash or otherwise,
without the prior written consent of the Placement Agent (which consent may be withheld in its sole discretion), other than (i)
the Securities to be sold pursuant to the Purchase Agreements, (ii) the issuance of shares of Common Stock, options to acquire
shares of Common Stock or other equity awards for shares of Common Stock pursuant to the Company’s employee benefit plans,
qualified stock option plans or other employee compensation plans as such plans are in existence on the date hereof and the issuance
of shares of Common Stock pursuant to the exercise, vesting or settlement of such options or other equity awards, and (iii) the
issuance of shares of Common Stock pursuant to the exercise of the Warrants and other warrants or rights to purchase the shares
of Common Stock outstanding or in existence on the date hereof. The Company agrees not to make any public announcement during the
Lock-Up Period of any intention to undertake any of the transactions described in clauses (1), (2) or (3) above. The Company further
agrees not to accelerate the vesting of any option or warrant or the lapse of any repurchase right prior to the expiration of the
Lock-Up Period.

 

     

     

    

 

(c)              
Stabilization. The Company will not take, directly or indirectly, any action designed, or that might reasonably be
expected to cause or result in, or that will constitute, stabilization or manipulation of the price of any security of the Company
to facilitate the sale or resale of any of the Securities.

 

(d)              
Investment Company Act. Neither the Company nor any Subsidiary shall invest or otherwise use the proceeds received
by the Company from its sale of the Securities in such a manner as would require the Company to register as an investment company
under the Investment Company Act.

 

Section 4.              
Costs and Expenses.

 

The Company, whether
or not the transactions contemplated hereunder are consummated or this Agreement is terminated, will pay or reimburse if paid by
the Placement Agent all costs and expenses incident to the performance of the Company’s obligations under this Agreement
and in connection with the transactions contemplated hereby, including but not limited to costs and expenses of or relating to
(i) the issue, sale and delivery of the Securities including any stock or transfer taxes and stamp or similar duties payable upon
the sale, issuance or delivery of the Securities and any printing, delivery, shipping of the certificates representing the Securities,
(ii) the fees and expenses of any transfer agent or registrar for the Securities, (iii) fees, disbursements and other charges of
counsel to the Company, (iv) listing fees for the listing or quotation of the Shares and Warrant Shares on the NASDAQ Capital Market,
and (v) the costs and expenses of the Company that were advanced by the Placement Agent in connection with the marketing of the
Offering and the sale of the Securities to prospective investors including, but not limited to, those related to any presentations
or meetings undertaken in connection therewith; provided that the amounts reimbursed to the Placement Agent by the Company
pursuant to this Section 4 and Section 7, if applicable, shall not exceed $35,000 in the aggregate.

 

It is understood that
except as provided in this Section 4, Section 6 and Section 7 hereof, the Placement Agent shall pay all of
its own expenses.

 

Section 5.              
Conditions of Placement Agent’s Obligations.

 

The obligations of
the Placement Agent hereunder are subject to the following conditions:

 

(a)              
No Action Preventing Issuance. No action shall have been taken and no statute, rule, regulation or order shall have
been enacted, adopted or issued by any governmental agency or body which would, as of the Closing Date, prevent the issuance or
sale of the Securities, and no injunction, restraining order or order of any other nature by any federal or state court of competent
jurisdiction shall have been issued as of the Closing Date which would prevent the issuance or sale of the Securities.

 

     

     

    

 

(b)              
No Material Adverse Change.

 

(i)                
Prior to the Closing, there shall not have occurred any change, or any development involving a prospective change, in the
condition, financial or otherwise, or in the earnings, business or operations of the Company and its Subsidiaries from that set
forth in the SEC Reports that, in the Placement Agent’s judgment, is material and adverse and that makes it, in the Placement
Agent’s judgment, impracticable to market the Securities.

 

(ii)             
There shall not have occurred any of the following: (A) a suspension or material limitation in trading in securities generally
on the New York Stock Exchange, the NASDAQ Stock Market, the NASDAQ Global Select Market, the NASDAQ Global Market, the NASDAQ
Capital Market, the NYSE American or the over-the-counter market or the establishing on such exchanges or markets by the SEC or
by such exchanges or markets of minimum or maximum prices that are not in force and effect on the date hereof; (B) a suspension
or material limitation in trading in the Company’s securities on the NASDAQ Stock Exchange or any other exchange or market
or the establishing on any such market or exchange by the SEC or by such market of minimum or maximum prices that are not in force
and effect on the date hereof; (C) a general moratorium on commercial banking activities declared by either federal or any state
authorities; (D) the outbreak or escalation of hostilities involving the United States or the declaration by the United States
of a national emergency or war, which in the Placement Agent’s judgment makes it impracticable or inadvisable to proceed
with the Offering or the delivery of the Securities in the manner contemplated in the Purchase Agreement; or (E) any calamity or
crisis, change in national, international or world affairs, act of God, change in the international or domestic markets, or change
in the existing financial, political or economic conditions in the United States or elsewhere, that in the Placement Agent’s
judgment makes it impracticable or inadvisable to proceed with the Offering or the delivery of the Securities in the manner contemplated
in the Purchase Agreement.

 

(c)              
Representations and Warranties. Each of the representations and warranties of the Company contained herein shall
be true and correct when made and on and as of the date hereof and the Closing Date, as if made on such date (except that those
representations and warranties that address matters only as of a particular date shall remain true and correct as of such date),
and all covenants and agreements herein contained to be performed on the part of the Company and all conditions herein contained
to be fulfilled or complied with by the Company at or prior to the Closing Date shall have been duly performed, fulfilled or complied
with in all material respects.

 

(d)              
Lock-Up Agreements. On or before the Closing Date, the Company shall have obtained for the benefit of the Placement
Agent the agreement, in the form set forth as Exhibit B hereto, of the persons and entities listed on Schedule I

(e)              
Opinion of Counsel to the Company. The Placement Agent shall have received from Olshan
Frome Wolosky LLP, counsel for the Company, such counsel’s written opinion in form and substance as is reasonably satisfactory

Officers’ Certificate. The Placement Agent shall have received on the Closing Date a certificate of the Company,
addressed to the Placement Agent and dated the Closing Date, signed by the Chief Executive Officer or the President and the principal
financial or accounting officer of the Company to the effect that the signers of such certificate have carefully examined the SEC
Reports, as well as any marketing materials used in connection with the offering of the Securities and this Agreement, and that:

 

(i)                
each of the representations, warranties and agreements of the Company in this Agreement were true and correct when originally
made and are true and correct as of the date hereof and the Closing Date (except that those representations and warranties that
address matters only as of a particular date shall remain true and correct as of such date); and the Company has complied with
all agreements and satisfied all the conditions on its part required under this Agreement to be performed or satisfied at or prior
to the Closing Date; and

 

(ii)             
since the date of the most recent financial statements included in the SEC Reports, there has been no material adverse effect
on the condition (financial or otherwise), prospects, earnings, business or properties of the Company and its Subsidiaries, taken

If any condition specified
in this Section 5 is not satisfied when and as required to be satisfied, this Agreement may be terminated by the Placement
Agent by notice to the Company at any time prior to the Closing Date, which termination shall be without liability on the part
of any party to any other party, except that Section 4, Section 6 and Section 7 hereof shall at all times
be effective and shall survive such termination.

 

Section 6.              
Indemnification and Contribution.

 

(a)              
Indemnification of the Placement Agent. The Company agrees to indemnify and hold harmless the Placement Agent, its
affiliates, directors, officers and employees, and agents who have or who are alleged to have participated in the distribution
of the Securities as Placement Agent and each person who controls the Placement Agent within the meaning of either the Securities
Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them
may become subject under the Securities Act, the Exchange Act or other Federal or state statutory law or regulation, at common
law 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 on (i) the breach
of any representation, warranty, covenant or agreement made by the Company herein or in the Purchase Agreement or (ii) any untrue
statement or alleged untrue statement of a material fact or a material omission by or on behalf of the Company for the purpose
of offering and selling the Securities pursuant to the Purchase Agreement; provided that this indemnity shall not apply
(x) to the extent that such loss, claim, liability, expense or damage resulted from the bad faith, willful misconduct or gross
negligence of the Placement Agent or (y) to any matter for which the Placement Agent agrees to indemnify the Company hereunder.
This indemnity agreement will be in addition to any liability which the Company may otherwise have.

 

     

     

    

 

(b)              
Indemnification of the Company. The Placement Agent agrees to indemnify and hold harmless the Company, each of its
directors, each of its senior executive officers and each person who controls the Company within the meaning of either the Securities
Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to the Placement Agent, but only with respect
to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged
untrue statement or omission made in reliance upon and in conformity with any information relating to the Placement Agent furnished
to the Company expressly for use in facilitating the offer and sale of the Securities.

 

(c)              
Notice and Procedures. Promptly after receipt by an indemnified party under this Section 6 of notice of the
commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 6, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify
the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did
not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and
defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than
the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel
of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action
for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however,
that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint
counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel
(including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel
if (w) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a
conflict of interest, (x) the actual or potential defendants in, or targets of, any such action include both the indemnified party
and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available
to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (y)
the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party
within a reasonable time after notice of the institution of such action or (z) the indemnifying party shall authorize the indemnified
party to employ separate counsel at the expense of the indemnifying party; provided, however, that an indemnifying
party shall not be liable for the fees and expenses of more than one such separate counsel (in addition to local counsel) in connection
with any proceeding or related proceeding in the same jurisdiction. An indemnifying party shall not be liable for any settlement
of any proceeding effected without its consent (which consent shall not be unreasonably withheld). Notwithstanding the foregoing
sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for
fees and expenses of counsel as contemplated by Section 6(a) or (b) hereof, the indemnifying party agrees that it
shall be liable for any settlement of any proceeding effected without its written consent if (A) such settlement is entered into
more than 60 days after receipt by such indemnifying party of the aforesaid request, (B) such indemnifying party shall have received
notice of the terms of such settlement at least 30 days before such settlement is entered into and (C) such indemnifying party
shall not have reimbursed the indemnified party in accordance with such request or disputed in good faith the indemnified party’s
entitlement to such reimbursement prior to the date of such settlement. An indemnifying party will not, without the prior written
consent (which consent shall not be unreasonably withheld) of the indemnified parties, settle or compromise or consent to the entry
of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification
or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or
action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding and does not include an admission of fault.

 

     

     

    

 

(d)              
Contribution. In the event that the indemnity provided in paragraph (b) or (c) of this Section 6 is unavailable
to or insufficient to hold harmless an indemnified party for any reason, the Company and the Placement Agent severally agree to
contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection
with investigating or defending the same) (collectively “Losses”) to which the Company and the Placement Agent
may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and
by the Placement Agent on the other from the offering of the Securities.

 

If the allocation
provided by the immediately preceding sentence is unavailable for any reason, the Company and the Placement Agent severally shall
contribute 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 of the Placement Agent on the other in connection with the statements or omissions which resulted in such Losses
as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total
net proceeds from the Offering (before deducting expenses) received by it, and benefits received by the Placement Agent shall be
deemed to be equal to the Placement Fee. Relative fault shall be determined by reference to, among other things, whether any untrue
or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information
provided by the Company on the one hand or the Placement Agent on the other, the intent of the parties and their relative 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 contribution were determined by pro rata allocation or any other method of allocation
which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph
(d), in no event shall the Placement Agent be required to contribute any amount in excess of the amount by which the Placement
Fee received by the Placement Agent with respect to the offering of the Securities exceeds the amount of any damages that the Placement
Agent has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.
Notwithstanding the provisions of this paragraph (d), 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.
For purposes of this Section 6, each person who controls the Placement Agent within the meaning of either the Securities
Act or the Exchange Act and each director, officer, employee, affiliate and agent of the Placement Agent shall have the same rights
to contribution as the Placement Agent, and each person who controls the Company within the meaning of either the Securities Act
or the Exchange Act, each senior executive officer of the Company and each director of the Company shall have the same rights to
contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

 

     

     

    

 

(e)              
Representations and Agreements to Survive Delivery. The obligations of the Company under this Section 6 shall
be in addition to any liability which the Company may otherwise have. The indemnity and contribution agreements of the parties
contained in this Section 6 and the covenants, warranties and representations of the Company contained in this Agreement
shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation
made by or on behalf of the Placement Agent, any person who controls the Placement Agent within the meaning of either the Securities
Act or the Exchange Act or any affiliate of the Placement Agent, or by or on behalf of the Company, its directors or officers or
any person who controls the Company within the meaning of either the Securities Act or the Exchange Act, and (iii) the issuance
and delivery of the Securities. The Company and the Placement Agent agree promptly to notify each other of the commencement of
any proceeding against it and, in the case of the Company, against any of the Company’s officers or directors in connection
with the issuance and sale of the Securities.

 

Section 7.              
Termination.

 

If (i) this Agreement
shall be terminated by the Placement Agent pursuant to Section 5 hereof or (ii) the sale of the Securities to Purchasers
is not consummated because of any failure, refusal or inability on the part of the Company to comply with the terms or perform
any agreement or obligation of this Agreement or any Purchase Agreement, other than by reason of a default by the Placement Agent,
the Company will, in addition to paying the amounts described in Section 4 hereof, reimburse the Placement Agent for all
of its reasonable, documented and actual out-of-pocket disbursements (including, but not limited to, the reasonable and documented
fees and disbursements of its outside counsel); provided that the amounts reimbursed to the Placement Agent by the Company
pursuant to Section 4 and this Section 7 shall not exceed $35,000 in the aggregate.

All statements, requests,
notices and agreements hereunder shall be in writing or by facsimile or email transmission, and:

herein, and shall be owed solely to the Company. Each party hereto disclaims any intention to impose any fiduciary or similar duty
on any other party hereto. Additionally, the Placement Agent has not acted as a financial advisor, nor has advised or is advising,
the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction with respect
to the transactions contemplated hereby. The Company shall consult with its own advisors concerning such matters and shall be responsible
for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Placement Agent shall
have no responsibility or liability to the Company with respect thereto. Any review by the Placement Agent of the Company, the
transactions contemplated hereby or other matters relating to such transactions has been and will be performed solely for the benefit
of the Placement Agent and has not been and shall not be performed on behalf of the Company or any other person. It is understood
that the Placement Agent has not and will not be rendering an opinion to the Company as to the fairness of the terms of the Offering.

and releases, to the fullest extent permitted by law, any claims that the Company may have against the Placement Agent with respect
to any breach or alleged breach of fiduciary duty.

Amendments and Waivers.

 

No supplement, modification
or waiver of this Agreement shall be binding unless executed in writing by the party to be bound thereby. The failure of a party
to exercise any right or remedy shall not be deemed or constitute a waiver of such right or remedy in the future. No waiver of
any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof (regardless
of whether similar), nor shall any such waiver constitute a continuing waiver unless otherwise expressly provided.
