    2

     

    

 

2.                 
BUYER’S REPRESENTATIONS AND WARRANTIES. Each Buyer, severally and not jointly, represents and warrants with respect
to only itself to the Company that, as of the date hereof and as of the Closing Date:

 

(a)              
Organization and Existence. Such Buyer is a duly incorporated or organized and validly existing corporation, limited partnership,
limited liability company or other legal entity, has all requisite corporate, partnership or limited liability company power and authority
to enter into and consummate the transactions contemplated by the Transaction Documents (as defined below) and to carry out its obligations
hereunder and thereunder, and to invest in the Common Shares pursuant to this Agreement, and is in good standing under the laws of the
jurisdiction of its incorporation or organization.

 

(b)              
No Public Sale or Distribution. Such Buyer is acquiring the Common Shares for its own account, not as nominee or agent,
for the purpose of investment and not with a view towards, or for resale in connection with, the public sale or distribution thereof,
except pursuant to sales registered or exempted under the 1933 Act; provided, however, that by making the representations
herein, such Buyer does not agree to hold any of the Common Shares for any minimum or other specific term and reserves the right to dispose
of the Common Shares at any time in accordance with or pursuant to a registration statement or an exemption under the 1933 Act. Such Buyer
is acquiring the Common Shares hereunder in the ordinary course of its business. Such Buyer does not presently have any agreement or understanding,
directly or indirectly, with any Person to distribute any of the Common Shares. For purposes of this Agreement, “Person”
means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an unincorporated organization
and a government or any department or agency thereof.

 

(c)              
Accredited Investor Status; No Disqualification Events. Such Buyer is (i) an “accredited investor” as that term
is defined in Rule 501(a) of Regulation D and (ii) an “Institutional Account” as defined in FINRA Rule 4512(c). Such Buyer
has executed and delivered to the Company a questionnaire in the form attached hereto as Exhibit B (the “Investor Questionnaire”),
to the extent applicable, which such Buyer represents and warrants is true, correct and complete. Such Buyer is a sophisticated institutional
investor with sufficient knowledge and experience in investing in private equity transactions to properly evaluate the risks and merits
of its purchase of the Common Shares. None of the “bad actor” disqualifications described in Rule 506(d)(1)(i) through (viii)
under the 1933 Act (“Disqualification Events”) are applicable to such Buyer or any of its Rule 506(d) Related Parties
(as defined below), except, if applicable, for a Disqualification Event as to which Rule 506(d)(2)(ii) or (iii) or (d)(3) is applicable.
Such Buyer hereby agrees that it shall notify the Company promptly in writing in the event a Disqualification Event becomes applicable
to such Buyer or any of its Rule 506(d) Related Parties, except, if applicable, for a Disqualification Event as to which Rule 506(d)(2)(ii)
or (iii) or (d)(3) is applicable. For purposes of this Section 2(c), “Rule 506(d) Related Party” shall mean
a Person that is a beneficial owner of such Buyer’s securities for purposes of Rule 506(d) of the 1933 Act. Except as set forth
on Schedule 2(c), such Buyer is not, and has not been, for a period of at least three (3) months prior to the date of this Agreement
(a) an officer or director of the Company, (b) an “affiliate” of the Company (as defined in Rule 144) (an “Affiliate”),
or (c) a “beneficial owner” of more than 10% of the Company’s Common Stock (as defined for purposes of Rule 13d-3 of
the 1934 Act (as defined below)).

 

(d)              
No General Solicitation. Such Buyer did not learn of the investment in the Common Shares as a result of any general or public
advertising or, to such Buyer’s knowledge, general solicitation, or publicly disseminated advertisements or sales literature, including
(a) any advertisement, article, notice or other communication published in any newspaper, magazine, website, or similar media, or
broadcast over television or radio, or (b) any seminar or meeting to which such Buyer was invited by any of the foregoing means of
communications.

 

    3

     

    

 

(e)              
Brokers and Finders. No Person will have, as a result of the transactions contemplated by the Transaction Documents, any
valid right, interest or claim against or upon the Company or a Buyer for any commission, fee or other compensation pursuant to any agreement,
arrangement or understanding entered into by, on behalf of such Buyer.

 

(f)               
Short Sales and Confidentiality Prior to the Date Hereof. Other than consummating the transactions contemplated hereunder,
such Buyer has not, nor has any Person acting on behalf of such Buyer or pursuant to any understanding with such Buyer, directly or indirectly
executed any purchases or sales, including “short sales” (as defined in Rule 200 of Regulation SHO under the 1934 Act), of
the securities of the Company, including any derivatives, during the period commencing as of the time that such Buyer was first contacted
by the Company or any other Person regarding the transactions contemplated hereby and ending immediately prior to the date hereof. 
Notwithstanding the foregoing, in the case of a Buyer that is a multi-managed investment vehicle whereby separate portfolio managers manage
separate portions of such Buyer’s assets and the portfolio managers have no direct knowledge of the investment decisions made by
the portfolio managers managing other portions of such Buyer’s assets, the representation set forth above shall only apply with
respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Common Shares covered
by this Agreement. Other than to other Persons party to this Agreement and other than to such Person’s outside attorney, accountant,
auditor or investment advisor only to the extent necessary to permit evaluation of the investment, and the performance of the necessary
or required tax, accounting, financial, legal, or administrative tasks and services and other than as may be required by law, as of the
date of this Agreement such Buyer has maintained the confidentiality of all disclosures made to it in connection with this transaction
(including the existence and terms of this transaction). Notwithstanding the foregoing, for avoidance of doubt, nothing contained herein
shall constitute a representation or warranty, or preclude any actions, with respect to the identification of the availability of, or
securing of, available shares to borrow in order to effect “short sales” or similar transactions in the future.

 

(g)              
Reliance on Exemptions. Such Buyer understands that the Common Shares are being offered and sold to it in reliance on specific
exemptions from the registration requirements of U.S. federal and state securities laws and that the Company is relying in part upon the
truth and accuracy of, and such Buyer’s compliance with, the representations, warranties, agreements, acknowledgments and understandings
of such Buyer set forth herein in order to determine the availability of such exemptions and the eligibility of such Buyer to acquire
the Common Shares.

 

(h)              
Information. Such Buyer has been furnished with all materials relating to the business, finances and operations of the Company
and materials relating to the transactions contemplated hereunder that have been requested by such Buyer. Such Buyer has been afforded
the opportunity to ask questions of the Company. Neither such inquiries nor any other due diligence investigations conducted by such Buyer
or its representatives shall modify, amend or affect such Buyer’s right to rely on the Company’s representations and warranties
contained herein. Such Buyer acknowledges that all of the documents filed by the Company with the SEC under Sections 13(a), 14(a) or 15(d)
of the 1934 Act that have been posted on the SEC’s EDGAR site are available to such Buyer, and such Buyer has not relied on any
statement of the Company not contained in such documents or in this Agreement (including all schedules attached hereto) in connection
with such Buyer’s decision to enter into this Agreement and the transactions contemplated hereby. Such Buyer has not relied on any
information or advice furnished by or on behalf of any other Buyer in connection with the transaction contemplated hereby.

 

    4

     

    

 

(i)                
Risk. Such Buyer understands that its investment in the Common Shares involves a high degree of risk. Such Buyer is able
to bear the risk of an investment in the Common Shares, including, without limitation, the risk of total loss of its investment. Such
Buyer has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect
to the transactions contemplated hereby. Such Buyer understands that there is no assurance that the Common Shares will continue to be
quoted, traded or listed for trading or quotation on the Nasdaq Capital Market (“Nasdaq”) or on any other organized
market or quotation system.

 

(j)                
Intentionally Omitted.

 

(k)              
No Governmental Review. Such Buyer understands that no U.S. federal or state agency or any other government or governmental
agency has passed on or made any recommendation or endorsement of the Common Shares or the fairness or suitability of the investment in
the Common Shares nor have such authorities passed upon or endorsed the merits of the offering of the Common Shares.

 

(l)                
Residency. Such Buyer’s office in which its investment decision with respect to the Common Shares was made is located
at the address immediately below such Buyer’s name on its signature page hereto.

 

(m)               Transfer
or Resale. Such Buyer acknowledges and agrees that the Common Shares are “restricted securities” as defined in Rule 144
promulgated under the 1933 Act as in effect from time to time (or a successor rule thereto) (“Rule 144”) and must
be held indefinitely unless they are subsequently registered under the 1933 Act or an exemption from such registration is available.
Such Buyer has been advised or is aware of the provisions of Rule 144, which permits limited resale of shares purchased in a private
placement subject to the satisfaction of certain conditions, including, among other things: the availability of certain current public
information about the Company during a certain period of time, if any, the resale occurring following the required holding period under
Rule 144 and under certain circumstances the number of shares being sold during any three-month period not exceeding specified limitations.

 

(n)              
Authorization; Validity; Enforcement. Such Buyer has all requisite power and authority to enter into this Agreement and
the other Transaction Documents to which such Buyer is a party, to carry out its obligations hereunder and to consummate the transactions
contemplated hereby. This Agreement and the other Transaction Documents to which such Buyer is a party have been duly and validly authorized,
executed and delivered by such Buyer and shall constitute the legal, valid and binding obligations of such Buyer enforceable against such
Buyer in accordance with their respective terms, except as such enforceability may be limited by general principles of equity or to applicable
bankruptcy, insolvency, reorganization, moratorium, liquidation and other similar laws relating to, or affecting generally, the enforcement
of applicable creditors’ rights and remedies.

 

    5

     

    

 

(o)              
Legends. Such Buyer understands that the certificates or other instruments representing the Common Shares, until such time
as the exchange or resale of the Common Shares have been registered under the 1933 Act, may bear a restrictive legend in the following
form (and a stop-transfer order may be placed against transfer of such Common Shares):

 

THE SECURITIES REPRESENTED HEREBY HAVE
NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF ANY STATE.
THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER
THE ACT AND APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM. INVESTORS SHOULD BE AWARE THAT THEY MAY
BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE SECURITIES MAY REQUIRE
AN OPINION OF COUNSEL IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS
IN COMPLIANCE WITH THE ACT.

 

In addition, if any Buyer is
an affiliate of the Company, the Common Shares issued to such Buyer may bear the following “affiliates” legend:

 

THE SHARES REPRESENTED BY THIS CERTIFICATE
ARE HELD BY AN AFFILIATE OF THE ISSUER AS DEFINED IN RULE 144 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”),
AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IN COMPLIANCE WITH THE REQUIREMENTS OF RULE 144 OR PURSUANT TO A REGISTRATION STATEMENT
UNDER SAID ACT OR AN EXEMPTION FROM SUCH REGISTRATION.

 

(p)              
No Conflicts. The execution, delivery and performance by such Buyer of this Agreement and the other Transaction Documents
to which such Buyer is a party and the consummation by such Buyer of the transactions contemplated hereby and thereby will not (i) result
in a violation of the organizational documents of such Buyer or (ii) conflict with, or constitute a default (or an event which with notice
or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation
of, any agreement, indenture or instrument to which such Buyer is a party, or (iii) result in a violation of any law, rule, regulation,
order, judgment or decree (including federal and state securities laws) applicable to such Buyer, except in the case of clauses (ii) and
(iii) above, for such conflicts, defaults, rights or violations which would not, individually or in the aggregate, reasonably be expected
to have a material adverse effect on the ability of such Buyer to perform its obligations hereunder.

 

(q)              
Current Ownership. As of the date hereof, each Buyer’s (and its Affiliates) ownership of Company securities (including
any derivatives), if any, is set forth on Schedule 2(q).

 

    6

     

    

 

(r)               
Forward Looking Statements. In connection with the due diligence investigation of the Company by each Buyer, such Buyer
has received and may continue to receive after the date hereof from the Company certain estimates, projections, forecasts, regulatory
approval expectations and other forward-looking information, as well as certain business plan information, regarding the Company and its
affiliates and subsidiaries and their respective businesses and operations. Such Buyer hereby acknowledges and agrees (a) that there are
uncertainties inherent in attempting to make such estimates, projections, forecasts, regulatory approval expectations and other forward-looking
statements, as well as business plans, (b) to take full responsibility for making its own evaluation of the adequacy and accuracy of all
such estimates, projections, forecasts, regulatory approval expectations and other forward-looking statements, as well as such business
plans, so furnished to it (including the reasonableness of the assumptions underlying such estimates, projections, forecasts, forward-looking
statements or business plans), and (c) that the Company has not made and is not making any express or implied representation or warranty
with respect to such estimates, projections, forecasts, regulatory approval expectations, forward-looking statements or business plans
(including the reasonableness of the assumptions underlying such estimates, projections, forecasts, regulatory approval expectations,
forward-looking statements or business plans).

 

3.                 
REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

 

The Company represents and warrants
to each of the Buyers that, as of the date hereof and as of the Closing Date, except as set forth in the SEC Reports (as defined below),
which SEC Reports shall be deemed a part hereof, and except as set forth on the Disclosure Schedule attached hereto as Exhibit C
(the “Disclosure Schedule”) (references to a “Schedule” in this Agreement shall be deemed to refer to a
schedule contained in the Disclosure Schedule unless otherwise expressly provided):

 

(a)              
Organization and Qualification. The Company and each of its subsidiaries is an entity duly organized and validly existing
and in good standing under the laws of its jurisdiction of formation, and has the requisite corporate (or other) power and authorization
to own its properties and to carry on its business as now being conducted and as presently proposed to be conducted. The Company and each
of its subsidiaries is duly qualified as a foreign corporation to do business and is in good standing in every jurisdiction in which its
ownership of property or the nature of the business conducted by it makes such qualification necessary, except to the extent that the
failure to be so qualified or be in good standing would not reasonably be expected to have a Material Adverse Effect. As used in this
Agreement, “Material Adverse Effect” means any material adverse effect on (i) the business, properties, assets, liabilities,
operations, results of operations or condition (financial or otherwise) of the Company or any of its subsidiaries, individually or taken
as a whole, or (ii) on the transactions contemplated hereby and the other Transaction Documents or (iii) on the other Transaction Documents
or by the agreements and instruments to be entered into in connection herewith or therewith, or (iv) on the authority or ability of the
Company to perform any of its obligations under any of the Transaction Documents or (v) on the legality, validity, binding effect or enforceability
of any of the Transaction Documents, except that any of the following, either alone or in combination, shall not be deemed a Material
Adverse Effect: (a) effects caused by changes or circumstances affecting general market or other conditions in the U.S. economy or which
are generally applicable to the industry in which the Company operates, provided that such effects are not borne to a materially disproportionate
degree by the Company compared to other companies operating in the same industry as the Company, (b) effects resulting from or relating
to the announcement or disclosure of the sale of the Common Shares or other transactions contemplated by this Agreement, (c) effects caused
by any event, occurrence or condition resulting from or relating to the taking of any action in accordance with this Agreement or the
Transaction Documents, or (d) effects resulting from Hatch-Waxman based litigation relating to the Company’s LIQ861 product candidate.
Except as set forth in the SEC Reports or as set forth on Schedule 3(a), the Company does not, directly or indirectly, own any
of the capital stock or hold an equity or similar interest in any entity.

(b)              
Authorization; Enforcement; Validity. The Company has the requisite corporate power and authority to enter into and perform
its obligations under this Agreement, the Registration Rights Agreement, the Standstill Agreement (as defined in Section 5(vi))
and each of the other agreements entered into by the Company in connection with the transactions contemplated by this Agreement (collectively,
the “Transaction Documents”) and to issue the Common Shares in accordance with the terms hereof and thereof. The execution
and delivery of this Agreement and the other Transaction Documents by the Company and the consummation by the Company of the transactions
contemplated hereby and thereby, including, without limitation, the issuance of the Common Shares, have been duly authorized by the Company’s
Board of Directors and (other than the filing of a Form D with the SEC and any other filings as may be required by any state securities
agencies), no further filing, consent or authorization is required by the Company, its Boards of Directors or its stockholders. This Agreement
and the other Transaction Documents have been duly executed and delivered by the Company, and constitute the legal, valid and binding
obligations of the Company, enforceable against the Company in accordance with their respective terms, except as such enforceability may
be limited by general principles of equity or applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws
relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies.

 

(c)              
Issuance of Common Shares. The issuance of the Common Shares at the Closing is duly authorized and, upon issuance in accordance
with the terms of the Transaction Documents, the Common Shares shall be validly issued and free from all preemptive or similar rights
(except for those which have been validly waived prior to the date hereof), taxes, liens and charges and other encumbrances with respect
to the issue thereof and the Common Shares shall be fully paid and nonassessable with the holders being entitled to all rights accorded
to a holder of Company Common Stock. Assuming the accuracy of each of the representations and warranties set forth in Section 2
of this Agreement, the offer and issuance by the Company of the Common Shares is exempt from registration under the 1933 Act. The offer
and issuance of the Common Shares hereunder will not obligate the Company to issue shares of Company Common Stock or other securities
to any other Person (other than the Buyers) and will not result in the adjustment of the exercise, conversion, exchange or reset price
of any outstanding security.

 

(d)              
No Conflicts. The execution, delivery and performance of the Transaction Documents by the Company and the consummation by
the Company of the transactions contemplated hereby and thereby (including, without limitation, the issuance of the Common Shares) will
not (i) result in a violation of the Company’s certificate of incorporation, as amended and restated and as in effect on the date
hereof or on the Closing, as applicable (the “Certificate of Incorporation”), or the Company’s bylaws, as amended
and restated and as in effect on the date hereof or on the Closing, as applicable (the “Bylaws”), or (ii) conflict
with, or constitute a default (or an event which with notice or lapse of time or both would become a default) in any respect under, or
give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which
the Company is a party, or (iii) result in a violation of any applicable law, rule, regulation, order, judgment or decree (including foreign,
federal and state securities laws and regulations and the rules and regulations of Nasdaq) applicable to the Company or by which any property
or asset of the Company is bound or affected, except, in the case of clauses (ii) and (iii) above, as would not have or reasonably be
expected to result in a Material Adverse Effect.

 

(e)              
Consents. The Company is not required to obtain any consent from, authorization or order of, or make any filing or registration
with (other than the filing of a Form D with the SEC and any other filings as may be required by any state securities agencies), any court,
governmental agency or any regulatory or self-regulatory agency or any other Person in order for it to execute, deliver or perform any
of its obligations under or contemplated by the Transaction Documents, in each case, in accordance with the terms hereof or thereof. All
consents, authorizations, orders, filings and registrations which the Company is required to obtain pursuant to the preceding sentence
have been obtained or effected on or prior to the Closing Date.

(f)               
Acknowledgment Regarding Buyer’s Purchase of Common Shares. The Company acknowledges and agrees that each Buyer is
acting solely in the capacity of an arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated
hereby and thereby and that, except as set forth on Schedule 3(f), no Buyer is (i) an officer or director of the Company, (ii)
an “affiliate” of the Company (as defined in Rule 144) or (iii) to the knowledge of the Company, a “beneficial owner”
(as defined for purposes of Rule 13d-3 of the 1934 Act) of more than 10% of the Company Common Stock. The Company further acknowledges
that no Buyer is acting as a financial advisor or fiduciary of the Company or any other Buyer (or in any similar capacity) with respect
to the Transaction Documents and the transactions contemplated hereby and thereby, and any advice given by a Buyer or any of its representatives
or agents in connection with the Transaction Documents and the transactions contemplated hereby and thereby is merely incidental to such
Buyer’s purchase of the Common Shares. The Company further represents to each Buyer that the Company’s decision to enter into
the Transaction Documents has been based solely on the independent evaluation by the Company and its representatives.

 

(g)              
SEC Reports; Financial Statements. The Company has filed all reports, schedules, forms, statements and other documents required
to be filed by the Company, if any, under the 1933 Act and the Securities Exchange Act of 1934, as amended (the “1934 Act”),
including pursuant to Section 13(a) or 15(d) of the 1934 Act, for the twelve (12) months preceding the date of this Agreement (the foregoing
materials, including the exhibits thereto and documents incorporated by reference therein, being collectively referred to herein as the
 “SEC Reports”) on a timely basis or has received a valid extension of such time of filing and has filed any such SEC
Reports prior to the expiration of any such extension. As of their respective dates, the SEC Reports complied in all material respects
with the requirements of the 1933 Act and the 1934 Act, as applicable, and none of the SEC Reports, when filed, contained any untrue statement
of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein,
in the light of the circumstances under which they were made, not misleading. The financial statements of the Company included in the
SEC Reports comply in all material respects with applicable accounting requirements and the rules and regulations of the Securities Exchange
Commission (the “SEC”) with respect thereto as in effect at the time of filing. Such financial statements have been

lease, dividend or other obligation of another Person if the primary purpose or intent of the Person incurring such liability, or the
primary effect thereof, is to provide assurance to the obligee of such liability that such liability will be paid or discharged, or that
any agreements relating thereto will be complied with, or that the holders of such liability will be protected (in whole or in part) against
loss with respect thereto.

 

(s)               
Absence of Litigation. Except as set forth in the SEC Reports or on Schedule 3(s), there is no action, suit, proceeding,

terminate such officer’s employment with the Company. No executive officer or other key employee of the Company 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 contract or agreement or any restrictive covenant, and the continued employment of each such executive
officer or other key employee (as the case may be) does not subject the Company to any liability with respect to any of the foregoing
matters. The Company is in compliance with all federal, state, local and foreign laws and regulations respecting labor, employment and
employment practices and benefits, terms and conditions of employment and wages and hours, except where failure to be in compliance would
not, either individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect.

 

    13

     

    

 

(u)              
Title. The Company has good and marketable title in fee simple to all real property and good and marketable title to all
personal property owned by it which is material to the business of the Company, in each case free and clear of all liens, encumbrances
and defects except such as do not materially affect the value of such property and do not interfere with the use made and proposed to
be made of such property by the Company. Any real property and facilities held under lease by the Company is held by it under valid, subsisting
and enforceable leases with such exceptions as are not material and do not interfere with the use made and proposed to be made of such
property and buildings by the Company.

 

(v)              
Intellectual Property Rights. The Company and each of its subsidiaries owns, free and clear of all liens, encumbrances and
defects, or has obtained valid and enforceable licenses for, all Intellectual Property (as defined below) (i) described in the SEC Reports

as currently proposed to be conducted, in each case as such business is described in the SEC Reports (collectively, with respect to the
Company and/or any of its subsidiaries, the “Company Intellectual Property”).  To the Company’s knowledge: 
(i) there are no third parties (including any present or former employees or contractors of the Company or any of its subsidiaries)
who have rights to any Company Intellectual Property, except for customary reversionary rights of third-party licensors, and the conduct
of the Company’s or any of its subsidiaries’ businesses as currently conducted or as currently proposed to be conducted (as
such business is described in the SEC Reports) does not infringe, misappropriate or otherwise violate the Intellectual Property of any
third party; and (ii) there is no infringement, misappropriation or other violation by third parties of any Company Intellectual
Property.  Except as set forth in Schedule 3(v), there is no pending or, to the Company’s knowledge, threatened action,
suit, proceeding or claim by others: (A) challenging the Company’s or any of its subsidiaries’ rights in or to any Company
Intellectual Property, and the Company is unaware of any facts which would form a reasonable basis for any such action, suit, proceeding
or claim; (B) challenging the validity, enforceability or scope of any Company Intellectual Property, and the Company is unaware
of any facts which would form a reasonable basis for any such action, suit, proceeding or claim; or (C) asserting that the Company
or any of its subsidiaries infringes, misappropriates or otherwise violates, or would, upon the commercialization of any product or service
described in the SEC Reports as under development, infringe, misappropriate or otherwise violate, any Intellectual Property rights of
others, and the Company is not aware of any facts which would form a reasonable basis for any such action, suit, proceeding or claim. 
The Company has complied in all material respects with the terms of each agreement pursuant to which Intellectual Property has been licensed
to the Company or any of its subsidiaries, and all such agreements are in full force and effect.  The products or product candidates
described in the SEC Reports (each a “Company Product”) as under development by the Company or any of its subsidiaries
fall within the scope of the claims of one or more patents or patent applications owned by, or exclusively licensed to, the Company or
any of its subsidiaries, the rights of the Company or any of its subsidiaries under which entitle (or in the case of patent applications,
once issued, would entitle) the Company or any of its subsidiaries to claim in good faith that a third party should cease the manufacture,
use, sale or importation of such Company Product. The Company has taken commercially reasonable efforts to protect, enforce and maintain
the material Company Intellectual Property. All present or former employees, consultants or independent contractors involved the development
of any material Company Intellectual Property have executed written agreements under which he, she or it assigns all rights to such Intellectual
Property to the Company or any of its subsidiaries and agrees to protect Company’s and its subsidiaries’ trade secrets and
other confidential information. The term “Intellectual Property” means all intellectual property rights, including
inventions, patents, trademarks, trade names, service names, Internet domain names, copyrights, copyrightable works, and trade secrets
and other confidential or proprietary information, and all registration or applications (including, as applicable, any renewals, reissues,
reexaminations, continuations, continuations-in-part, or divisionals thereof) for any of the foregoing.

Effect. The term “Environmental Laws” means all federal, state, local or foreign laws relating to pollution or protection
of human health or the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface
strata), including, without limitation, laws relating to emissions, discharges, releases or threatened releases of chemicals, pollutants,
contaminants, or toxic or hazardous substances or wastes (collectively, “Hazardous Materials”) into the environment,

and procedures reasonably designed to promote and achieve compliance with the laws referred to in (iii) above and with this representation
and warranty; neither the Company nor any of its affiliates will directly or indirectly use the proceeds of the Common Shares or lend,
contribute or otherwise make available such proceeds to any subsidiary, affiliate, joint venture partner or other Person for the purpose
of financing or facilitating any activity that would violate the laws and regulations referred to in (iii) above; there are, and have
been, no allegations, investigations or inquiries with regard to a potential violation of any Anti-Bribery Laws by the Company or its
affiliates, or any of their respective current or former directors, officers, employees, stockholders, representatives or agents, or other
Persons acting or purporting to act on their behalf.

 

    17

     

    

 

(ee)           
No Disqualification Events. Neither the Company nor any of its predecessors, any affiliated issuer, any director, executive
officer, other officer of the Company participating in the offering hereunder, any beneficial owner of 20% or more of the Company’s
outstanding voting equity securities, calculated on the basis of voting power, nor any promoter (as that term is defined in Rule 405 under
the 1933 Act) connected with the Company in any capacity at the time of sale (each, an “Issuer Covered Person” and,
together, “Issuer Covered Persons”) is subject to any Disqualification Event, except, if applicable, for a Disqualification
Event as to which Rule 506(d)(2)(ii) or (iii) or (d)(3) is applicable. The Company has exercised reasonable care to determine whether
any Issuer Covered Person is subject to a Disqualification Event. The Company has complied, to the extent applicable, with its disclosure
obligations under Rule 506(e), and has furnished to the Buyers a copy of any disclosures provided thereunder.

 

(ff)             
Disclosure. The Company confirms that none of them nor any other Person acting on their behalf has provided any of the Buyers
or their agents or counsel with any information that constitutes or could reasonably be expected to constitute material, non-public information
concerning the Company, other than the existence of, and information related to, the transactions contemplated by this Agreement and the
other Transaction Documents. The Company understands and confirms that each of the Buyers will rely on the foregoing representations in
effecting transactions in securities of the Company. All disclosure provided to the Buyers regarding the Company each of its subsidiaries,
their respective businesses and the transactions contemplated hereby, including the schedules to this Agreement, furnished by or on behalf
of the Company is true and correct and does not contain any untrue statement of a material fact or omit to state any material fact necessary
in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. All of the
written information furnished after the date hereof by or on behalf of the Company to you pursuant to or in connection with this Agreement
and the other Transaction Documents, taken as a whole, will be true and correct in all material respects as of the date on which such
information is so provided and will not contain any untrue statement of a material fact or omit to state any material fact necessary in
order to make the statements made therein, in the light of the circumstances under which they are made, not misleading. Each press release
issued by the Company and filed as an exhibit to an SEC Report during the twelve (12) months preceding the date of this Agreement did
not at the time of release contain any untrue statement of a material fact or omit to state a material fact required to be stated therein
or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. No
event or circumstance has occurred or information exists with respect to the Company or its business, properties, liabilities, prospects,
operations (including results thereof) or conditions (financial or otherwise), which, under applicable law, rule or regulation, requires
public disclosure at or before the date hereof or announcement by the Company but which has not been so publicly disclosed. The Company
acknowledges and agrees that no Buyer makes or has made any representations or warranties with respect to the transactions contemplated
hereby other than those specifically set forth in Section 2.

 

(gg)          
Disclosure Controls. The Company maintains systems of internal accounting controls designed to provide reasonable assurance
that (a) transactions are executed in accordance with management’s general or specific authorizations; (b) transactions are recorded
as necessary to permit preparation of financial statements in conformity with GAAP applied on a consistent basis during the periods involved
and to maintain asset accountability; (c) access to assets is permitted only in accordance with management’s general or specific
authorization; and (d) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate
action is taken with respect to any differences. Other than as set forth in the SEC Reports, the Company is not aware of any material
weaknesses or significant deficiencies in its internal control over financial reporting. To the knowledge of the Company, since the date
of the latest audited financial statements of the Company included within the SEC Reports, there has been no change in the Company’s
internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s
internal control over financial reporting. The Company has established disclosure controls and procedures (as defined in 1934 Act Rules
13a-15 and 15d-15) for the Company and designed such disclosure controls and procedures to ensure that material information relating to
the Company is made known to the certifying officers by others within the Company, particularly during the period in which the Company’s
Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, is being prepared. The Company’s certifying officers
evaluated the effectiveness of the Company’s controls and procedures as of a date within 90 days prior to the filing date of the
Annual Report on Form 10-K for the fiscal year most recently ended (such date, the “Evaluation Date”). The Company
presented in its Annual Report on Form 10-K for the fiscal year most recently ended the conclusions of the certifying officers about the
effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date,
there have been no significant changes in the Company’s internal controls (as such term is defined in Item 307(b) of Regulation
S-K under the 1933 Act) or, to the Company’s knowledge, in other factors that would significantly adversely affect the Company’s
internal controls. To the knowledge of the Company, the Company’s “internal control over financial reporting” and “disclosure
controls and procedures” (as such terms are defined under the 1934 Act) are effective at a reasonable assurance level.

 

    18

     

    

 

(hh)          
Clinical Data and Regulatory Compliance.  The preclinical tests and clinical trials, and other studies (collectively,
 “studies”) that are described in, or the results of which are referred to in, the SEC Reports were and, if still pending,
are being conducted in all material respects in accordance with the protocols, procedures and controls designed and approved for such
studies and with standard medical and scientific research procedures; each description of the results of such studies is accurate and
complete in all material respects and fairly presents the data derived from such studies, and the Company does not have any knowledge
of any other studies the results of which are materially inconsistent with, or otherwise call into question, the results described or
referred to in the SEC Reports. Each of the Company and its subsidiaries has made all such filings and obtained all such approvals as
may be required by the Food and Drug Administration of the U.S. Department of Health and Human Services or any committee thereof or from
any other U.S. or foreign government or drug or medical device regulatory agency, or health care facility Institutional Review Board (collectively,
the “Regulatory Agencies”) based on the location and nature of the relevant study; the Company has not received any
notice of, or correspondence from, any Regulatory Agency requiring the termination, suspension or modification of any clinical trials
that are described or referred to in the SEC Reports; and each of the Company and its subsidiaries has operated and currently is in compliance
in all material respects with all applicable rules, regulations and policies of the Regulatory Agencies.

 

(ii)             
Compliance with Health Care and Privacy Laws.  Each of the Company and its subsidiaries is, and at all times has been,
in material compliance with all applicable Health Care and Privacy Laws. For purposes of this Agreement, “Health Care and

U.S.C. Sections 286 and 287, and the health care fraud criminal provisions under the U.S. Health Insurance Portability and Accountability
Act of 1996 (“HIPAA”) (42 U.S.C. Section 1320d et seq.), the exclusion laws (42 U.S.C. Section 1320a-7),
the statutes, regulations and directives of applicable government funded or sponsored healthcare programs, and the regulations promulgated

(the “Privacy Rule”), the Security Standards, and the Standards for Electronic Transactions and Code Sets promulgated
under HIPAA, the Health Information Technology for Economic and Clinical Health Act (42 U.S.C. Section 17921 et seq.), and the
regulations promulgated thereunder and any state or non-U.S. counterpart thereof or other law or regulation the purpose
of which is to protect the privacy of individuals or prescribers; (iv) the Patient Protection and Affordable Care Act of 2010, as

foreign laws, relating to the regulation of the Company, including any of the foregoing concerning data security or privacy (including
the collection, use, storage, processing or disposal of any information that identifies or could reasonably be used to identify any natural
Person). Neither the Company nor any of its subsidiaries has received written notice of any claim, action, suit, proceeding, hearing,
enforcement, investigation, arbitration or other material action from any court or arbitrator or governmental or regulatory authority
or third party alleging that any product, operation or activity is in violation of any Health Care and Privacy Laws nor is any such claim,
action, suit, proceeding, hearing, enforcement, investigation, arbitration or other action threatened. Each of the Company and each of
its subsidiaries has filed, obtained, maintained or submitted all material reports, documents, forms, notices, applications, records,
claims, submissions and supplements or amendments as required by any Health Care and Privacy Laws, and all such reports, documents, forms,
notices, applications, records, claims, submissions and supplements or amendments were in all material respects timely, complete, accurate
and not misleading on the date filed (or were corrected or supplemented by a subsequent submission). Neither the Company or any of its
subsidiaries has received written notice of any claim, action, suit, proceeding, hearing, enforcement, investigation is a party to any
corporate integrity agreements, monitoring agreements, consent decrees, settlement orders, or similar agreements with or imposed by any
governmental or regulatory authority. Additionally, neither the Company, any of its subsidiaries nor any of their respective employees,
officers or directors has been excluded, suspended or debarred from participation in any U.S. federal health care program or human clinical

(jj)             
No Additional Agreements. The Company has no other agreements or understandings (including, without limitation, side letters)
with any Buyer to purchase Common Shares on terms more favorable to such Buyer than as set forth herein.

 

(kk)           
Manipulation of Price.  Neither the Company nor, to the knowledge of the Company, any Person acting on its behalf,
directly or indirectly, (i) has taken any action designed to cause or to result in the stabilization or manipulation of the price of any
security of the Company to facilitate the sale or resale of any of the Common Shares, (ii) sold, bid for, purchased, or paid any compensation
for soliciting purchases of, any of the Common Shares, or (iii) paid or agreed to pay to any Person any compensation for soliciting another
to purchase any other securities of the Company.

 

(ll)             
Eligibility for Registration. As of the Closing, the Company is eligible to register the Common Shares for resale by the
Buyers using Form S-3 promulgated under the 1933 Act.

 

(mm)          
Transfer Taxes. On the Closing Date, all stock transfer or other taxes (other than income or similar taxes) which are required
to be paid in connection with the issuance, sale and transfer of the Common Shares to be sold to each Buyer hereunder will be, or will
have been, fully paid or provided for by the Company, and all laws imposing such taxes will be or will have been complied with.

 

(nn)           
Bank Holding Company Act. Neither the Company nor any of its subsidiaries or affiliates is subject to the Bank Holding Company
Act of 1956, as amended (the “BHCA”) and to regulation by the Board of Governors of the Federal Reserve System (the
 “Federal Reserve”). Neither the Company nor any of its subsidiaries or affiliates owns or controls, directly or indirectly,
five percent (5%) or more of the outstanding shares of any class of voting securities or twenty-five percent (25%) or more of the total
equity of a bank or any entity that is subject to the BHCA and to regulation by the Federal Reserve. Neither the Company nor any of its
subsidiaries or affiliates exercises a controlling influence over the management or policies of a bank or any entity that is subject to
the BHCA and to regulation by the Federal Reserve.

 

(oo)          
Insurance. As applicable, each of the Company and its subsidiaries is insured by insurers of recognized financial responsibility
against such losses and risks and in such amounts as management of the Company believes to be prudent and customary in the businesses
in which the Company and its subsidiaries are engaged. Neither the Company nor any of its subsidiaries have been refused any insurance
coverage sought or applied for and neither the Company nor any of its subsidiaries has any reason to believe that it will be unable to
renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be
necessary to continue its business at a cost that would not have a Material Adverse Effect.

 

(pp)           
Sarbanes-Oxley Act. The Company is in compliance with any and all applicable requirements of the Sarbanes-Oxley Act of 2002,
as amended, that are effective as of the date hereof, and any and all applicable rules and regulations promulgated by the SEC thereunder
that are effective as of the date hereof, except where the failure to be in such compliance would not have, individually or in the aggregate,
a Material Adverse Effect.

 

(qq)           
Off Balance Sheet Arrangements. There is no transaction, arrangement, or other relationship between the Company or any of
its subsidiaries and an unconsolidated or other off balance sheet entity that is required to be disclosed by the Company in its 1934 Act
filings and is not so disclosed or that otherwise would be reasonably likely to have a Material Adverse Effect.

 

    20

     

    

 

4.             COVENANTS.

 

(a)              
Commercially Reasonable Efforts. Each party shall use its commercially reasonable efforts timely to satisfy each of the
covenants and the conditions to be satisfied by it as provided in Section 5 and Section 6 of this Agreement.

 

(b)             No
Conflicting Agreements. The Company will not take any action, enter into any agreement or make any commitment that would conflict
or interfere in any respect with the Company’s obligations to the Buyers under the Transaction Documents.

 

(c)              
Nasdaq Listing. Until the date the Buyers have sold all of the Common Shares (the “Reporting Period”),
the Company will use commercially reasonable efforts to continue the listing and trading of Company Common Stock on Nasdaq, and, in accordance
therewith, will use commercially reasonable efforts to comply with the Company’s reporting, filing and other obligations under the
bylaws or rules of such market or exchange, as applicable.

 

(d)             Reporting
Status. During the Reporting Period, the Company shall timely file all reports required to be filed with the SEC pursuant to the
1934 Act, and the Company shall not terminate its status as an issuer required to file reports under the 1934 Act even if the 1934 Act
or the rules and regulations thereunder would otherwise permit such termination and the Company shall take all actions necessary to maintain
its eligibility to register the Common Shares for resale by the Buyers on Form S-3.

 

(e)              Transfer
or Resale. Notwithstanding any other provision of the Transaction Documents, each Buyer covenants that the Common Shares may be disposed
of only pursuant to an effective registration statement under, and in compliance with the requirements of, the 1933 Act, or pursuant
to an available exemption from, or in a transaction not subject to, the registration requirements of the 1933 Act, and in compliance
with any applicable state and federal securities laws. In connection with any transfer of the Common Shares other than (i) pursuant to
an effective registration statement, (ii) pursuant to Rule 144 at a time when the transferor is not at the time of the sale, or during
the ninety (90) days immediately preceding such sale, an affiliate of the Company, or (iii) to the Company, the Company may require the
transferor thereof to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable to the Company,
provided that Schulte Roth & Zabel LLP shall be deemed reasonably acceptable to the Company, the form and substance of which opinion
shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Common
Shares under the 1933 Act. Notwithstanding the foregoing, provided that no affiliate of such Buyer serves on the Board of Directors of
the Company, the Common Shares may be pledged in connection with a bona fide margin account or other loan or financing arrangement secured
by the Common Shares and such pledge of Common Shares shall not be deemed to be a transfer, sale or assignment of the Common Shares hereunder,
and no such Buyer effecting a pledge of Common Shares shall be required to provide the Company with any notice thereof or otherwise make
any delivery to the Company pursuant to this Agreement or any other Transaction Document, including, without limitation, this Section
4(e).

 

    21

     

    

 

(f)               
Removal of Legends. Subject to the Company’s right to request an opinion of counsel as set forth in Section 4(e),
the legend set forth in Section 2(o) shall be removed and the Company shall issue or cause to be issued a certificate or book-entry
evidence of ownership without such legend or any other legend (except for any “affiliates” legend as set forth in Section
2(o) to the extent applicable) to the holder of the applicable Common Shares upon which it is stamped, if (i) such Common Shares are
registered for resale pursuant to an effective registration statement under the 1933 Act, (ii) such Common Shares are eligible to be sold
pursuant to Rule 144 at a time the transferor is not, and has not been for ninety (90) days prior to such time, an affiliate of the Company
or (iii) such Common Shares are sold or transferred in compliance with Rule 144, including without limitation in compliance with the current
public information requirements of Rule 144 if applicable to the Company at the time of such sale or transfer, and, in the cases of clauses
(ii) and (iii), the holder and its broker have delivered customary documents reasonably requested by counsel to the Company in connection
with such sale or transfer, provided that such documents shall not include a legal opinion if the Common Shares are proposed to be as
described in clauses (i), (ii) or (iii) set forth in Section 4(e). Any fees (with respect to the counsel to the Company or otherwise)
associated with the removal of such legend shall be borne by the Company.

 

(g)              
Use of Proceeds. The Company shall use the proceeds from the sale of the Common Shares in a manner consistent with the Company’s
public statements and filings and for general corporate purposes, but not for (i) the repayment of any outstanding Indebtedness (other
than in connection with the potential refinancing of the Company’s credit facility existing on the date hereof) or (ii) the redemption
or repurchase of any equity securities (other than in connection with net issuances pursuant to the Company’s equity plans existing
on the date hereof).

 

(h)               
Fees. The Company and the Buyers shall each pay the fees and expenses of their respective advisers, counsel, accountants
and other experts, if any, and all other expenses incurred by such party in connection with the negotiation, preparation, execution, delivery
and performance of this Agreement.

 

(i)                Short
Sales and Confidentiality After the Date Hereof.  Each Buyer covenants that neither it nor any Affiliates acting on its behalf
or pursuant to any understanding with it will execute any “short sales” during the period from the date hereof until the
earlier of such time as (i) the transactions contemplated by this Agreement are first publicly announced or (ii) this Agreement
is terminated in full. Each Buyer covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed
by the Company, such Buyer will maintain the confidentiality of all disclosures made to it in connection with this transaction (including
the existence and terms of this transaction), other than to such Person’s outside attorney, accountant, auditor or investment advisor
only to the extent necessary to permit evaluation of the investment, and the performance of the necessary or required tax, accounting,
financial, legal, or administrative tasks and services and other than as may be required by law. Notwithstanding the foregoing, for avoidance
of doubt, nothing contained herein shall preclude any actions with respect to the identification of the availability of, or securing
of, available shares to borrow in order to effect “short sales” or similar transactions in the future. Each Buyer understands
and acknowledges that the SEC currently takes the position that coverage of “short sales” of shares of the Common Stock “against
the box” prior to effectiveness of a resale registration statement with securities included in such registration statement would
be a violation of Section 5 of the 1933 Act, as set forth in Item 239.10 of the Securities Act Rules Compliance and Disclosure Interpretations
compiled by the Office of Chief Counsel, Division of Corporation Finance.

 

    22

     

    

 

(j)            Notice
of Disqualification Events. The Company will notify the Buyers in writing, prior to the Closing Date of (i) any Disqualification
Event relating to any Issuer Covered Person and (ii) any event that would, with the passage of time, become a Disqualification Event
relating to any Issuer Covered Person, in each case of which it is aware.

 

(k)              
Subsequent Equity Sales.

 

(i)                
From the date hereof until 90 days after the Closing Date, without the prior written consent of the Buyers, the Company shall not
offer to sell, sell, contract to sell, grant any option to sell or otherwise dispose of any Company Common Stock or securities convertible
into or exchangeable for Company Common Stock, warrants or any rights to purchase or acquire, Company Common Stock prior to the termination
of this Agreement; provided, however, that such restrictions will not be required in connection with the Company’s
Excluded Securities (as defined below).

 

(ii)             
As used in this Agreement, (i) “Business Day” means any day, excluding Saturday, Sunday and any day which is
a legal holiday in the City of New York or is a day on which banking institutions located in the City of New York are authorized or required
by law or other governmental action to close; (ii) “Excluded Securities” means (a) issuance or sale of Company
Common Stock, options to purchase Company Common Stock, or Company Common Stock issuable upon the exercise of options, restricted stock
units or other equity awards to any employee or director share option, incentive or benefit plan, share purchase or ownership plan, long-term
incentive plan, option exchange program, dividend reinvestment plan, inducement award under the rules of Nasdaq or other compensation
plan of Company Common Stock, whether now in effect or hereafter implemented, disclosed in the SEC Reports (or, in the case of an inducement
award under Nasdaq rules, disclosed by press release), (b) issuance or sale of Company Common Stock issuable upon exchange, conversion
or redemption of securities or the exercise or vesting of warrants, options, restricted stock units or other equity awards outstanding
at the date of this Agreement or disclosed in the SEC Reports and (c) issuance or sale of Company Common Stock or securities convertible
into or exchangeable for Company Common Stock as consideration for mergers, acquisitions, other business combinations, joint ventures
or strategic alliances, marketing or distribution arrangements, collaboration agreements, co-promotion agreements or intellectual property
license agreements occurring after the date of this Agreement but shall not include a transaction in which the Company is issuing securities
for the purpose of raising capital or to an entity whose primary business is investing in securities, provided, that the aggregate number
of Company Common Stock issued or issuable does not exceed 10% of the number of shares of Company Common Stock outstanding immediately
following the Closing.

 

(l)                
Form D and Blue Sky. The Company agrees to file a Form D with respect to the Common
Shares as required under Regulation D and to provide a copy thereof to each Buyer promptly after such filing. The Company shall, on or
before the Closing Date, take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for or
to qualify the Common Shares for sale to the Buyers at the Closing pursuant to this Agreement under applicable securities or “Blue
Sky” laws of the states of the United States (or to obtain an exemption from such qualification), and shall provide evidence of
any such action so taken to the Buyers on or prior to the Closing Date. The Company shall make all filings and reports relating to the
offer and sale of the Common Shares required under applicable securities or “Blue Sky” laws of the states of the United States
following the Closing Date.

 

    23

     

    

 

(m)            
No Integrated Offering. None of the Company, its affiliates nor any Person acting on their behalf will take any action or
steps that would require registration of the issuance of any of the Common Shares under the 1933 Act or cause the offering of any of the
Common Shares to be integrated with other offerings for purposes of any such applicable shareholder approval provisions.

(ix)

(x)             The Company Common Stock (I) shall be designated for quotation or listed on Nasdaq and (II) shall not have been suspended, as of

OF OBLIGATIONS TO EFFECT CLOSING; EFFECTS.

 

The obligations of the Company,
on the one hand, and the Buyers, on the other hand, to effect the Closing shall terminate as follows:

 

(i)               Upon the mutual written consent of the Company and Buyers that agreed to purchase a majority of the Common Shares to be issued
and sold pursuant to this Agreement;

 

(ii)             
By the Company if any of the conditions set forth in Section 5 shall have become incapable of fulfillment, and shall not
have been waived by the Company; or

 

(iii)            By a Buyer (with respect to itself only) if any of the conditions set forth in Section 6 shall have become incapable
of fulfillment, and shall not have been waived in writing by such Buyer;

 

provided, however, that,
except in the case of clause (i) above, the party seeking to terminate its obligation to effect the Closing shall not then be in breach
of any of its representations, warranties, covenants or agreements contained in this Agreement or the other Transaction Documents if such
breach has resulted in the circumstances giving rise to such party’s seeking to terminate its obligation to effect the Closing.

 

    26

     

    

 

In the event of termination by the Company or
any Buyer of its obligations to effect a Closing pursuant to this Section 7, written notice thereof shall be given to the
other Buyers by the Company and any Buyer shall have the right to terminate its obligations to effect the Closing upon written notice
to the Company. Nothing in this Section 7 shall be deemed to release any party from any liability for any breach by such party
of the terms and provisions of this Agreement or the other Transaction Documents or to impair the right of any party to compel specific
performance by any other party of its obligations under this Agreement or the other Transaction Documents.

 

8.             INDEMNIFICATION.

 

(a)       Indemnification.
The Company agrees to indemnify and hold harmless each Buyer and its Affiliates, and their respective directors, officers, trustees, members,
managers, employees, investment advisers and agents (collectively, the “Indemnitees”), from and against any and all
losses, claims, damages, liabilities and expenses (including without limitation reasonable and documented attorney fees and disbursements
and other documented out-of-pocket expenses reasonably incurred in connection with investigating, preparing or defending any action, claim
or proceeding, pending or threatened and the costs of enforcement thereof) to which such Person may become subject as a result of any
breach of representation, warranty, covenant or agreement made by or to be performed on the part of the Company under the Transaction
Documents, and will reimburse any such Person for all such amounts as they are incurred by such Person solely to the extent such amounts
have been judicially determined not to have resulted from such Person’s fraud, bad faith or willful misconduct. To the extent that
the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment
and satisfaction of each of the Indemnified Liabilities that is permissible under applicable law.

 

(b)       Conduct
of Indemnification Proceedings. Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying
party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such
claim with counsel reasonably satisfactory to the indemnified party; provided that any Person entitled to indemnification hereunder
shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel
shall be at the expense of such Person unless (a) the indemnifying party has agreed in writing to pay such fees or expenses, (b) the indemnifying
party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such Person or (c) in the reasonable
judgment of any such Person, based upon written advice of its counsel, a conflict of interest exists between such Person and the indemnifying
party with respect to such claims (in which case, if the person notifies the indemnifying party in writing that such Person elects to
employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense
of such claim on behalf of such Person); and provided, further, that the failure of any indemnified party to give written
notice as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure
to give notice shall materially adversely affect the indemnifying party in the defense of any such claim or litigation. It is understood
that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more
than one separate firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except with the prior written
consent of the indemnified party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim
or litigation. No indemnified party will, except with the consent of the indemnifying party, consent to entry of any judgment or enter
into any settlement.

 

    27

     

    

 

9.             MISCELLANEOUS.

 

(a)              
Governing Law; Jurisdiction; Jury Trial. This Agreement and any related dispute shall be governed by, and construed and
interpreted in accordance with, the laws of the State of New York applicable to contracts executed in and to be performed in that State,
without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions)
that would cause the application of the laws of any jurisdictions other than the State of New York. Each of the parties hereto hereby
(a) irrevocably submits to the personal jurisdiction of the Supreme Court of the State of New York and any state appellate court therefrom
within the State of New York (or, if the Supreme Court of the State of New York declines to accept jurisdiction over a particular matter,
any state or federal court within the State of New York) in the event that any dispute arises out of this Agreement or any of the transactions
contemplated by this Agreement, (b) agrees that it will not attempt to deny or defeat such personal jurisdiction or venue by motion or
other request for leave from any such court and (c) agrees that it will not bring any action relating to this Agreement or any of the
transactions contemplated by this Agreement in any court other than the Supreme Court of the State of New York and any state appellate
court therefrom within the State of New York (or, if the Supreme Court of the State of New York declines to accept jurisdiction over a
particular matter, any state or federal court within the State of New York). EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES,
TO THE EXTENT PERMITTED BY APPLICABLE LEGAL REQUIREMENTS, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, SUIT OR OTHER LEGAL PROCEEDING
ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

 

(b)              
Counterparts. This Agreement may be executed in two or more identical counterparts, all of which shall be considered one
and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party; provided
that a facsimile, .pdf or any other electronic signature complying with the U.S. federal ESIGN Act of 2000 (e.g., www.docusign.com) shall
be considered due execution and shall be binding upon the signatory thereto with the same force and effect as if the signature were an
original, not a facsimile, .pdf or other electronic signature.

 

(c)              
Headings. The headings of this Agreement are for convenience of reference and shall not form part of, or affect the interpretation
of, this Agreement.

 

    28

     

    

 

(d)              
Severability. If any provision of this Agreement is prohibited by law or otherwise determined to be invalid or unenforceable
by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended
to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall
not affect the validity of the remaining provisions of this Agreement so long as this Agreement as so modified continues to express, without
material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability
of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or
the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith
negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as
close as possible to that of the prohibited, invalid or unenforceable provision(s).

 

(e)              
Entire Agreement; Amendments. This Agreement and the other Transaction Documents supersede all other prior oral or written
agreements between the Company, its affiliates and Persons acting on their behalf, on the one hand, and the Buyers, their affiliates and
Persons acting on their behalf, on the other hand, with respect to the matters discussed herein, and this Agreement, the other Transaction
Documents and the instruments referenced herein and therein contain the entire understanding of the parties with respect to the matters
covered herein and therein and, except as specifically set forth herein or therein, neither the Company nor any Buyer makes any representation,
warranty, covenant or undertaking with respect to such matters. No provision of this Agreement may be amended other than by an instrument
in writing signed by the Company and the Required Holders, and any amendment to this Agreement made in conformity with the provisions
of this Section 9(e) shall be binding on all Buyers and permitted assignees Common Shares and the Company; provided, that
any such amendment or waiver that complies with the foregoing but that disproportionately, materially and adversely affects the rights
and obligations of any Buyer relative to the comparable rights and obligations of the other Buyers shall require the prior written consent
of such adversely affected Buyer (for the avoidance of doubt, participation by any Buyer in an unrelated financing by the Company shall
not be deemed to disproportionately affect the Buyers who do not participate in such financing). No provisions hereto may be waived other
than by an instrument in writing signed by the party against whom enforcement is sought. No such amendment shall be effective to the extent
that it applies to less than all of the Buyers or holders of the applicable Common Shares then outstanding. No consideration shall be
offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless
the same consideration (other than the reimbursement of legal fees) also is offered to all of the parties to the Transaction Documents
and holders of Common Shares, as the case may be. As used in this Agreement. “Required Holders” means Buyers or permitted
assignees of at least a majority of the aggregate amount of Common Shares issued and/or issuable hereunder and shall include the Lead
Investor so long as the Lead Investor or any of its Affiliates holds any Common Shares.

 

    29

Agreement or any of the other Transaction Documents must be in writing and will be deemed to have been delivered: (i) upon receipt, when
delivered personally; (ii) upon delivery, when sent by electronic mail (provided, that the sending party does not receive an automated
rejection notice); or (iii) one (1) Business Day after deposit with an overnight courier service, in each case properly addressed to the
party to receive the same. The addresses and e-mail addresses for such communications shall be:

Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their respective
successors and assigns, including any purchasers of the Common Shares. The Company shall not assign this Agreement or any rights or obligations
hereunder without the prior written consent of the Buyers. No Buyer may assign this Agreement or any rights or obligations hereunder without

their mutual intent, and no rules of strict construction will be applied against any party.

 

(l)                
Remedies. Each Buyer and each holder of the Common Shares shall have all rights and remedies set forth in the Transaction
Documents and all rights and remedies which such holders have been granted at any time under any other agreement or contract and all of
the rights which such holders have under any law. The parties agree that irreparable damage may occur in the event that any of the provisions
of the Transaction Documents were not performed in accordance with their specific terms or were otherwise breached and that monetary damages
may not be adequate compensation for any loss incurred by the Buyers or the Company by reason of any breach of any such provisions. As
such, the non-breaching party shall be entitled to seek equitable relief, including an injunction and specific performance, as a remedy
for any such breach.

 

(m)            
Independent Nature of Buyers’ Obligations and Rights. The obligations of each Buyer under any Transaction Document
are several and not joint with the obligations of any other Buyer, and no Buyer shall be responsible in any way for the performance of
the obligations of any other Buyer under any Transaction Document. Nothing contained herein or in any other Transaction Document, and
no action taken by any Buyer pursuant hereto or thereto, shall be deemed to constitute the Buyers as, and the Company acknowledges that
the Buyers do not so constitute, a partnership, an association, a joint venture or any other kind of entity, or create a presumption that
the Buyers are in any way acting in concert or as a group, and the Company shall not assert any such claim with respect to such obligations
or the transactions contemplated by the Transaction Documents and the Company acknowledges that the Buyers are not acting in concert or
as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. The Company acknowledges and
each Buyer confirms that it has independently participated in the negotiation of the transaction contemplated hereby with the advice of
its own counsel and advisors. Each Buyer shall be entitled to independently protect and enforce its rights, including, without limitation,
the rights arising out of this Agreement or out of any other Transaction Documents, and it shall not be necessary for any other Buyer

negotiation and execution of this Agreement by legal counsel of its own choice or has voluntarily declined to seek such counsel; and (c)
it understands the terms and consequences of this Agreement and is fully aware of the legal and binding effect of this Agreement. Each
Buyer understands that the Company has been represented in the preparation, negotiation and execution of this Agreement by DLA Piper LLP
(US) and that DLA Piper LLP (US) now or may in the future represent one or more Buyers or their affiliates in matters unrelated to the
transactions contemplated by this Agreement, including the representation of such Buyers or their affiliates in matters of a nature similar
to those contemplated by this Agreement. The Company and each Buyer hereby acknowledge that they have had an opportunity to ask for and
have obtained information relevant to such representation, including disclosure of the reasonably foreseeable adverse consequences of
such representation, and hereby waives any conflict arising out of such representation solely with respect to the matters contemplated
by this Agreement.

 

    31

     

    

 

(o)              
Publicity. Except as set forth below, no public release or announcement concerning the transactions contemplated hereby
shall be issued by the Buyers without the prior consent of the Company, except as such release or announcement may be required by law
or the applicable rules or regulations of any securities exchange or securities market, in which case the Buyers shall allow the Company
reasonable time to comment on such release or announcement in advance of such issuance. Notwithstanding the foregoing, each Buyer may
identify the Company, the transactions contemplated by the Transaction Documents and the value of such Buyer’s security holdings
in the Company in accordance with applicable investment reporting and disclosure regulations or internal policies without prior notice
to or consent or comment from the Company (including, for the avoidance of doubt, filings pursuant to Sections 13 and 16 of the 1934 Act).
The Company shall not include the name of any Buyer or any affiliate or investment adviser of such Buyer in any press release or public
announcement (which, for the avoidance of doubt, shall not include any SEC filing to the extent such disclosure is required by SEC rules
and regulations) without the prior written consent of such Buyer. By 8:30 a.m. (New York City time) on the Business Day immediately following
the date this Agreement is executed, the Company shall issue a press release disclosing all material terms of the transactions contemplated
by this Agreement and any other material nonpublic information that the Company may have provided any Buyer at any time prior to the filing
of such press release (the “Press Release”). From and after the issuance of the Press Release, no Buyer shall be in
possession of any material nonpublic information received from the Company, any of its subsidiaries or any of their respective officers,
directors, employees or agents. No later than 5:30 p.m. (New York City time) on the first Business Day following the date this Agreement
is executed, the Company will file a Current Report on Form 8-K attaching the press release described in the foregoing sentence as
well as copies of the Transaction Documents. In addition, the Company will make such other filings and notices in the manner and time
required by the SEC or Nasdaq. The Company shall not, and shall cause each of its officers, directors, employees and agents not to, provide

Registration Rights

 

2.1             
Provisions Relating to Company Registration.

 

(a)              
Filing.

 

(i)                
On or prior to the date that is one hundred eighty (180) days following the date hereof (the “Company Filing Deadline”),
the Company shall file with the SEC a Registration Statement on Form S-3 (or, subject to Section 2.1(a)(ii), such other appropriate
form) for an offering to be made on a delayed or continuous basis pursuant to Rule 415 (a “Shelf Registration Statement”)
pursuant to which all of the Shares sold at the Closing constituting Registrable Securities shall be registered for resale by such Holders
(a “Shelf Registration”).

 

(ii)             
If Form S-3 is not available for the Shelf Registration Statement for the resale of Registrable Securities, the Company shall (i)
register the resale of the Registrable Securities on another appropriate form and (ii) undertake to register the Registrable Securities
on Form S-3 as soon as such form is available, provided that the Company shall maintain the effectiveness of such Shelf Registration Statement
then in effect until such time as a Shelf Registration Statement on Form S-3 covering the Registrable Securities has been declared effective
by the SEC.

 

    5

     

    

 

(b)              
Effectiveness. The Company shall use its best efforts to cause the Shelf Registration Statement(s) filed pursuant to Section
2.1(a) to be declared effective by the SEC or otherwise become effective under the Securities Act as soon as practicable after the
filing thereof, but in no event later than the date that is the earlier of (i) in the event that such Shelf Registration Statement (x)
is not subject to a review by the SEC, sixty (60) calendar days after the earlier of (A) the Company Filing Deadline and (B) the date
such Shelf Registration Statement was filed with the SEC and (y) is subject to a review by the SEC, ninety (90) calendar days after the
earlier of (A) the Company Filing Deadline and (B) the date such Shelf Registration Statement was filed with the SEC and (ii) five (5)
Business Days after the date the Company receives written notification from the SEC that such Shelf Registration(s) will not be reviewed
(the “Initial Effectiveness Deadline”). The Company shall use its best efforts to maintain the effectiveness
of such Shelf Registration Statement(s), including by filing any necessary post-effective amendments and Prospectus supplements and by
filing one or more replacement or renewal Shelf Registration Statements upon the expiration of such Shelf Registration Statement(s), continuously
until such time as there are no Registrable Securities remaining. By 9:30 a.m. New York time on the Business Day following the date such
Shelf Registration Statement is declared effective by the SEC, the Company shall file with the SEC in accordance with Rule 424 under the
Securities Act the final prospectus to be used in connection with sales pursuant to such Shelf Registration Statement.

 

(c)              
Additional Registrable Securities; Additional Selling Stockholders. At any time and from time to time that a Shelf Registration
Statement is effective, if a Holder of Registrable Securities requests (i) the registration under the Securities Act of additional Registrable
Securities pursuant to such Shelf Registration Statement or (ii) that such Holder be added as a selling stockholder in such Shelf Registration
Statement, the Company shall as promptly as practicable amend or supplement the Shelf Registration Statement to cover such additional
Registrable Securities and/or Holder.

 

(d)              
Right to Effect Shelf Takedowns. Each Holder shall be entitled, at any time and from time to time when a Shelf Registration
Statement is effective, to sell any or all of the Registrable Securities covered by such Shelf Registration Statement (a “Shelf
Takedown”).

 

(e)              
Underwritten Offering. Any Holder or Holders intending to effect a Shelf Takedown or Demand Registration shall be entitled
to request, by written notice to the Company (an “Underwritten Offering Notice”), that such Shelf Takedown or
Demand Registration be an underwritten offering (an “Underwritten Offering”). The Underwritten Offering Notice
shall specify the number of Registrable Securities intended to be offered and sold by such Holder(s) pursuant to the Underwritten Offering.
The Company shall not be required to effect more than two (2) Underwritten Offerings during the term of this Agreement and shall not be
required to facilitate an Underwritten Offering unless (i) in the case of the first Underwritten Offering, such offering is for the lesser
of (a) expected aggregate gross proceeds of at least $5 million or (b) all of the remaining Registrable Securities of all Holders participating
in such offer and (ii) in the case of the second Underwritten Offering, the Holder(s) participating in such Underwritten Offering request
the inclusion in such Underwritten Offering of all of its or their remaining Registrable Securities (such amount, as applicable, the “Minimum
Amount”).

 

(f)               
Selection of Underwriters. The Holder(s) requesting an Underwritten Offering shall have the right to select the investment
banking firm(s) and manager(s) to administer such Underwritten Shelf Takedown, subject to the approval of the Company (which approval
shall not be unreasonably withheld, conditioned or delayed).

 

    6

     

    

 

(g)              
Rule 415 Cutbacks. Notwithstanding any other provision of this Agreement, if the staff of the SEC or any SEC Guidance sets
forth a limitation on the number of Registrable Securities permitted to be registered on a particular Shelf Registration Statement as
a secondary offering (and notwithstanding that the Company used diligent efforts to advocate with the staff of the SEC for the registration
of all or a greater portion of Registrable Securities), the Company shall reduce the number of Registrable Securities on a pro rata basis
based on the total number of unregistered Registrable Securities held by such Holders. In the event of a cutback hereunder, the Company
shall give each Holder at least five (5) Trading Days prior written notice along with the calculations as to such Holder’s allotment.
In the event the Company amends a Shelf Registration Statement in accordance with the foregoing, the Company will use its reasonable best
efforts to file with the SEC, on the earliest practical date on which the Company is permitted by SEC Guidance to file such additional
Shelf Registration Statement related to the Registrable Securities (the “Additional Filing Deadline”), one or
more Registration Statement(s) on Form S-3 (or such other form available as provided in Section 2.1(a)(ii)) to register for resale
those Registrable Securities that were not registered for resale on the initial Shelf Registration Statement and cause such Shelf Registration
Statement(s) to be declared effective on or prior to the earlier of (i) in the event that such additional Shelf Registration Statement
(x) is not subject to a review by the SEC, sixty (60) calendar days after the earlier of (A) the applicable Additional Filing Deadline
and (B) the date such additional Shelf Registration Statement was filed with the SEC and (y) is subject to a review by the SEC, ninety
(90) calendar days after the earlier of (A) the applicable Additional Filing Deadline and (B) the date such additional Shelf Registration
Statement was filed with the SEC and (ii) five (5) Business Days after the date the Company receives written notification from the SEC
that such additional Shelf Registration(s) will not be reviewed (the “Additional Effectiveness Deadline”). By
9:30 a.m. New York time on the Business Day following the date any such additional Shelf Registration Statement is declared effective
by the SEC, the Company shall file with the SEC in accordance with Rule 424 under the Securities Act the final prospectus to be used in
connection with sales pursuant to such additional Shelf Registration Statement.

 

(h)              
S-1 Demand Registrations. If the Company is not eligible to use a Form S-3 for the Shelf Registration, then, upon request
from Holders of fifty percent (50%) of the Registrable Securities then outstanding that the Company file
a registration statement on Form S-1 (a “Form
S-1 Registration Statement”) with respect to at least the Minimum Amount
then the Company shall (x) within ten (10) days after the date such request is given, give written notice thereof (the “Demand
Notice”) to all Holders other than the Initiating Holders; and (y) as soon as practicable, and in any event within sixty
(60) days after the date such request is delivered to the Company by the Initiating Holders, file a Form
S-1 Registration Statement under the Securities Act covering all Registrable Securities that the Initiating
Holders requested to be registered and any
additional Registrable Securities requested to be included in such registration by any other Holders, as specified by notice given by
each such Holder to the Company within twenty (20) days of the
date the Demand Notice is delivered to such Holder (a “Form S-1 Filing Deadline”)
and use its best efforts to cause such Form S-1 Registration
Statement to be declared effective by the SEC or otherwise become effective under the Securities Act as soon as practicable after
the filing thereof, but in no event later than the date that is the earlier of (i) in the event that such Form S-1 Registration Statement
(x) is not subject to a review by the SEC, sixty (60) calendar days after the earlier of (A) the applicable Form S-1 Filing Deadline and
(B) the date such Form S-1 Registration Statement was filed with the SEC and (y) is subject to a review by the SEC, ninety (90) calendar
days after the earlier of (A) the applicable Form S-1 Filings Deadline and (B) the date such Form S-1 Registration Statement was filed
with the SEC and (ii) five (5) Business Days after the date the Company receives written notification from the SEC that such Form S-1
Registration(s) will not be reviewed (a “Form
S-1 Effectiveness Deadline”), and in each case, subject to the limitations
of Section 2.1(e) (a “Demand Registration”).
 The Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to this Section 2.1(h)
during the period that is sixty (60) days before the Company’s good faith estimate of the date of filing of, and ending on a date
that is ninety (90) days after the effective date of, a Company-initiated registration. All
provisions set forth in this Agreement with respect to Shelf Registration Statements shall apply, mutatis, mutandis, to the Form
S-1 Registration Statements required to be filed hereunder (except to the extent expressly set forth in this Section 2.1(h)).

(iv)            
use reasonable best efforts to cause all Registrable Securities covered by any Registration Statement to be registered with or

Securities in accordance with the intended method or methods of disposition thereof;

with respect to the suspension of the qualification or exemption from qualification of any Registrable Securities for sale under the applicable
securities or blue sky laws of any jurisdiction or the initiation of any proceeding for such purpose;

 

(vii)         
in the event of the issuance of any stop order suspending the effectiveness of a Registration Statement, any order suspending or

of such Registrable Securities required to be stated therein or necessary to make the statements made therein not misleading in light

of the circumstances under which they were made; provided further, that each Holder of Registrable Securities, upon receipt of
any notice from the Company of any event of the kind described in this Section 2.2(a)(viii) shall forthwith discontinue disposition

and customary selling efforts related thereto, in each case to the same extent as if the Company were engaged in a primary underwritten
registered offering of its Common Stock; provided, that the Company’s obligation to make senior management available for
participation in “road show” presentations shall be limited to no more than one underwritten offering during any 12-month
period;

(b)              
Notwithstanding anything to the contrary contained in this Agreement, the Company shall not be required to include Registrable
Securities in any Registration Statement unless the Holder owning the Registrable Securities to be registered on the Registration Statement,
following reasonable advance written request by the Company, furnishes to the Company, no later than seven (7) Business Days after the
date on which the Company has given notice of the Company’s proposed filing of the Registration Statement, an executed stockholder
questionnaire in the form attached hereto as Exhibit A.

 

(c)              
Notwithstanding anything to the contrary, the Company shall cause its transfer agent to deliver unlegended shares of Common Stock
to a transferee of a Holder in connection with any sale of Registrable Securities with respect to which a Holder has entered into a contract
for sale, prior to the Holder’s receipt of a notice by the Company suspending dispositions pursuant to the applicable Registration
Statement and for which a Holder has not yet settled.

 

(d)              
Neither the Company nor any subsidiary or Affiliate thereof shall identify any Holder as an underwriter in any public disclosure
or filing with the SEC or any trading market and any Holder being deemed an underwriter by the SEC shall not relieve the Company of any
obligations it has under this Agreement; provided, however, that the foregoing shall not prohibit the Company from including
the disclosure found in the “Plan of Distribution” section attached hereto as Annex A to Exhibit A in the Registration Statement.

 

    13

     

    

 

2.3             
Participation in Underwritten Offerings. No Person may participate in any underwritten offering pursuant to this Agreement
unless such Person (a) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements in customary
form approved by the Persons entitled under this Agreement to approve such arrangements and (b) completes and executes all customary questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting
arrangements.

 

2.4             
Registration Expenses

 

(a)              
The Company shall bear all Registration Expenses.

 

(b)              
The obligation of the Company to bear and pay the Registration Expenses shall apply irrespective of whether a registration, once
properly demanded or requested, becomes effective or is withdrawn or suspended, including one (1) request by one or more Holder(s) to
withdraw any Registration Statement; provided, that, after such first request by one or more Holder(s), the Registration Expenses
for any Registration Statement withdrawn at the request of one or more Holder(s) shall be borne by such Holder(s).

 

2.5             
Indemnification.

 

(a)              
The Company shall, to the fullest extent permitted by law, indemnify and hold harmless each Holder, any Person who is or might
be deemed to be a “controlling person” of the Holder or any of its subsidiaries within the meaning of the Securities Act or
the Exchange Act (each such Person, a “Controlling Person”) and their respective direct and indirect general
and limited partners, advisory board members, directors, officers, trustees, managers, members, employees, agents, Affiliates and shareholders,
and each other Person, if any, who acts on behalf or controls any such Holder or Controlling Person (collectively, the “Holder
Indemnified Parties”) from and against any losses, claims, damages, liabilities or expenses, joint or several, or any actions
in respect thereof to which each Holder Indemnified Party may become subject under the Securities Act, Exchange Act, any state blue sky
securities laws, any equivalent non-U.S. securities laws or otherwise, insofar as such losses, claims, damages, liabilities, expenses
or actions arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in or incorporated
by reference in any Registration Statement or in any amendment thereof, in each case at the time such became effective under the Securities
Act, or in the preliminary Prospectus, free writing prospectus (as defined in Rule 405 under the Securities Act or any successor rule
thereto) or other information that is deemed, under Rule 159 promulgated under the Securities Act to have been conveyed to purchasers
of securities at the time of sale of such securities (“Disclosure Package”), in the Prospectus or in any amendment
thereof or supplement thereto or (ii) the omission or alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein (in the case of a Disclosure Package or any Prospectus, in the light of the circumstances
under which they were made) not misleading, and the Company shall reimburse, as incurred, the Holder Indemnified Parties for any legal
or other expenses reasonably incurred by them in connection with investigating, defending or settling any such loss, claim, damage, liability,
expense or action in respect thereof; provided, however, that the Company shall not be liable in any such case to the extent that
such loss, claim, damage, liability, expense or action arises out of or is based upon any untrue statement or omission made or incorporated
by reference in any such Registration Statement, the Disclosure Package, any Prospectus or in any amendment thereof or supplement thereto
in reliance upon and in conformity with written information pertaining to a Holder and furnished to the Company by or on behalf of such
Holder Indemnified Party specifically for inclusion therein; and provided further, however, that the Company shall not be liable
in any such case to the extent that such loss, claim, damage, liability, expense or action arises out of or is based upon any untrue statement
or alleged untrue statement or omission or alleged omission made in the Disclosure Package, where (A) such statement or omission had been
eliminated or remedied in any subsequently filed amended prospectus or prospectus supplement (the Disclosure Package, together with such
updated documents, the “Updated Disclosure Package”), the filing of which such Holder had been timely notified
in writing in accordance with the terms of this Agreement, (B) such Updated Disclosure Package was available at the time such Holder sold
Registrable Securities under the Registration Statement, (C) such Updated Disclosure Package was not furnished by such Holder to the Person
asserting the loss, liability, claim, damage, liability, expense or action, or an underwriter involved in the distribution of such Registrable
Securities, at or prior to the time such furnishing is required by the Securities Act, (D) the Updated Disclosure Package would have cured
the defect giving rise to such loss, liability, claim, damage, liability, expense or action, and (E) the Updated Disclosure Package was
provided to the Holder and the Holder failed to use such Updated Disclosure Package and such failure led to the loss, liability, claim,
damage, liability, expense or action. Such indemnity shall remain in full force and effect regardless of any investigation made by or
on behalf of any Holder Indemnified Parties and shall survive the transfer of the Registrable Securities by any Holder and the Company
shall reimburse such Holder, and each such director, officer, employees, Affiliates and agents for any legal or other expenses reasonably
incurred by them in connection with investigating, defending, or settling and such loss, claim, damage, liability, action, or proceeding.
Such indemnity shall remain in full force and effect, regardless of any investigation made by or on behalf of the Company or any such
director, officer, employees, Affiliates and agents and shall survive the transfer by a Holder of such Registrable Securities.

 

    14

     

    

 

(b)              
In connection with any registration in which a Holder of Registrable Securities is participating, each such Holder shall furnish
to the Company in writing such information as the Company reasonably requests for use in connection with any such Registration Statement
or Prospectus and shall to the fullest extent permitted by law, indemnify and hold harmless the Company, its directors and officers, employees,
agents and any Person who is or might be deemed to be a Controlling Person (a “Company Indemnified Party”) from
and against any losses, claims, damages, liabilities or expenses or any actions in respect thereof, to which a Company Indemnified Party
may become subject under the Securities Act, the Exchange Act, any state blue sky securities laws, any equivalent non-U.S. securities
laws or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon (i) any untrue statement
or alleged untrue statement of a material fact contained in the Registration Statement or in any amendment thereof, in each case at the
time such became effective under the Securities Act, or in any Disclosure Package, Prospectus or in any amendment thereof or supplement
thereto, or in any filing made in connection with the qualification of the offering under the securities or other “blue sky”
laws of any jurisdiction in which Registrable Securities are offered, (ii) the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein (in the case of the Disclosure Package or any Prospectus,
in the light of the circumstances under which they were made) not misleading, (iii) any violation or alleged violation by the Company
of the Securities Act, the Exchange Act, any other law, including, without limitation, any state securities law, or any rule or regulation
thereunder relating to the offer or sale of the Registrable Securities pursuant to a Registration Statement or (iv) any violation of this
Agreement, but in each of clauses (i) and (ii), only to the extent that the untrue statement or omission or alleged untrue statement or
omission was made in reliance upon and in conformity with written information pertaining to such Holder and furnished to the Company by
or on behalf of such Holder specifically for inclusion therein, and, subject to the limitation immediately preceding this clause, shall
reimburse, as incurred, Company Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating,
defending or settling any such loss, claim, damage, liability, expense or action in respect thereof. Such indemnity shall remain in full
force and effect regardless of any investigation made by or on behalf of such Holder, or any such director, officer, employees, Affiliates
and agents and shall survive the transfer of such Registrable Securities by such Holder. Such indemnity shall remain in full force and
effect, regardless of any investigation made by or on behalf of the Company or any such director, officer, employees, Affiliates and agents
and shall survive the transfer by a Holder of such Registrable Securities, and such Holder shall reimburse the Company, and each such
director, officer, employees, Affiliates and agents for any legal or other expenses reasonably incurred by them in connection with investigating,
defending, or settling and such loss, claim, damage, liability, action, or proceeding.

 

    15

     

    

 

(c)              
Promptly after receipt by a Holder Indemnified Party or a Company Indemnified Party (each, an “Indemnified Party”)
of notice of the commencement of any action or proceeding (including a governmental investigation), such Indemnified Party will, if a
claim in respect thereof is to be made against the indemnifying party under this Section 2.5, notify the indemnifying party in
writing of the commencement thereof; provided, that the omission to so notify the indemnifying party will not relieve the indemnifying
party from liability under Sections 2.5(a) or 2.5(b) unless and to the extent it did not otherwise learn of such action
and the indemnifying party has been materially prejudiced by such failure. In case any such action is brought against any Indemnified
Party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein
and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof at the
indemnifying party’s expense, with counsel reasonably satisfactory to such Indemnified Party (who shall not, except with the prior
written consent of the Indemnified Party, be counsel to the indemnifying party); provided, that any Indemnified Party shall continue
to be entitled to participate in the defense of such claim or action, with counsel of its own choice, but the indemnifying party shall
not be obligated to reimburse such Indemnified Party for any fees, costs and expenses subsequently incurred by the Indemnified Party in
connection with such defense unless (i) the indemnifying party has agreed in writing to pay such fees, costs and expenses, (ii) the indemnifying
party has failed to assume the defense of such claim or action within a reasonable time after receipt of notice of such claim or action,
(iii) having assumed the defense of such claim or action, the indemnifying party fails to employ counsel reasonably acceptable to the
Indemnified Party or to pursue the defense of such claim or action in a reasonably vigorous manner, (iv) the use of counsel chosen by
the indemnifying party to represent the Indemnified Party would present such counsel with a conflict of interest or (v) the Indemnified
Party has reasonably concluded that there may be one or more legal or equitable defenses available to it and/or other any other Indemnified
Party which are different from or additional to those available to the indemnifying party. In no event shall the indemnifying party be
liable for the fees and expenses of more than one counsel (together with appropriate local counsel) at any time for any Indemnified Party
in connection with any one action or separate but substantially similar or related actions arising in the same jurisdiction out of the
same general allegations or circumstances. An indemnifying party shall not be liable for any settlement of any action or claim referred
to in this Section 2.5 effected without its prior written consent, provided, however, that the indemnifying party
shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the prior written consent of the
Indemnified Party consent to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim
or litigation and such settlement shall not include any admission as to fault on the part of the Indemnified Party. Following indemnification
as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnified Party with respect to all third
parties, firms or corporations relating to the matter for which indemnification has been made.

 

    16

     

    

 

(d)              
If the indemnification provided for in this Section 2.5 is unavailable or insufficient to hold harmless an Indemnified Party
under Sections 2.5(a) or 2.5(b), 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 (or actions in respect thereof) referred to in Sections 2.5(a)
or 2.5(b) in such proportion as is appropriate to reflect the relative fault of the indemnifying party or parties on the one hand
and the Indemnified Party on the other in connection with the statements or omissions that resulted in such losses, claims, damages or
liabilities (or actions in respect thereof) as well as any other relevant equitable considerations. The relative fault of the parties
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 on the one hand or a Holder or Holder Indemnified
Party, as the case may be, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct
or prevent such statement or omission. 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 Section 2.5 shall be deemed to include any legal or other expenses reasonably incurred
by such Indemnified Party in connection with investigating or defending any action or claim that is the subject of this Section 2.5(d).
The parties agree that it would not be just and equitable if contributions were determined by pro rata allocation (even if a Holder
was treated as one Person for such purpose) or any other method of allocation that does not take account of the equitable considerations
referred to above. Notwithstanding anything else in this Agreement, in no event will a Holder be required to pay via indemnification or
contribution an amount in excess of its net proceeds of sales of Shares under the Registration Statement. 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.

until the date on which the Holder no longer hold any Registrable Securities, the Company shall:

 

(a)              
make and keep public information available, as those terms are understood and defined in Rule 144;

 

(b)

under the Securities Act and the Exchange Act; and

reporting requirements of Rule 144 and of the Securities Act and the Exchange Act.

Remedies; Specific Performance. In the event of a breach or a threatened breach by any party to this Agreement of its obligations
under this Agreement, any party injured or to be injured by such breach shall be entitled to specific performance of its rights under
this Agreement or to injunctive relief, in addition to being entitled to exercise all rights provided in this Agreement and granted by
law, it being agreed by the parties that the remedy at law, including monetary damages, for breach of any such provision will be inadequate

at law would be adequate is hereby waived.

 

4.2

thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right,
power or privilege.

 

4.3             
Further Assurances. Each party shall do and perform, or cause to be done and performed, all such further acts and things,

to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity,
legality and enforceability of the remaining provisions hereof, and the invalidity of a particular provision in a particular jurisdiction
shall not invalidate such provision in any other jurisdiction.

SELLING STOCKHOLDER NOTICE AND QUESTIONNAIRE

Notice Address: Liquidia Corporation

419 Davis Drive, Suite 100

Morrisville,
NC 27560

 

The undersigned holder of
shares of common stock of Liquidia Corporation (the “Company”) understands that the Company intends to file
with the Securities and Exchange Commission a registration statement on Form S-3 (the “Registration Statement”)
for the registration and the resale under Rule 415 of the Securities Act of 1933, as amended (the “Securities Act”),
of the Registrable Securities in accordance with the terms of the Common Stock Purchase Agreement, dated April 12, 2021, by and among
the Company and the several signatories thereto (the “Purchase Agreement”). All capitalized terms not otherwise

Annex A

 

PLAN OF DISTRIBUTION

 

We are registering the shares
of common stock previously issued, to permit the resale of these shares of common stock by the holders of the common stock from time to
time after the date of this prospectus. We will not receive any of the proceeds from the sale by the selling stockholders of the shares
of common stock. We will bear all fees and expenses incident to our obligation to register the shares of common stock.

 

The selling stockholders may
sell all or a portion of the shares of common stock beneficially owned by them and offered hereby from time to time directly or through
one or more underwriters, broker-dealers or agents. If the shares of common stock are sold through underwriters or broker-dealers, the
selling stockholders will be responsible for underwriting discounts or commissions or agent’s commissions. The shares of common
stock may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices
determined at the time of sale, or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block
transactions,

 

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

 

		·	in the over-the-counter market;

 

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

 

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

 

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

 

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

 

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

 

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

 

		·	privately negotiated transactions;

 

		·	short sales;

 

		·	sales pursuant to Rule 144;

 

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

 

		·	a combination of any such methods of sale; and

 

		·	any other method permitted pursuant to applicable law.

 

     

     

    

 

If the selling stockholders
effect such transactions by selling shares of common stock to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers
or agents may receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from
purchasers of the shares of common stock for whom they may act as agent or to whom they may sell as principal (which discounts, concessions
or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions
involved). In connection with sales of the shares of common stock or otherwise, the selling stockholders may enter into hedging transactions
with broker-dealers, which may in turn engage in short sales of the shares of common stock in the course of hedging in positions they
assume. The selling stockholders may also sell shares of common stock short and deliver shares of common stock covered by this prospectus
to close out short positions and to return borrowed shares in connection with such short sales. The selling stockholders may also loan
or pledge shares of common stock to broker-dealers that in turn may sell such shares.

 

The selling stockholders may
pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance
of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time to time pursuant
to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933,
as amended, amending, if necessary, the list of selling stockholders to include the pledgee, transferee or other successors in interest
as selling stockholders under this prospectus. The selling stockholders also may transfer and donate the shares of common stock in other
circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for
purposes of this prospectus.

 

The selling stockholders and
any broker-dealer participating in the distribution of the shares of common stock may be deemed to be “underwriters” within
the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be
deemed to be underwriting commissions or discounts under the Securities Act. At the time a particular offering of the shares of common
stock is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of shares of common
stock being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions
and other terms constituting compensation from the selling stockholders and any discounts, commissions or concessions allowed or reallowed
or paid to broker-dealers.

 

Under the securities laws
of some states, the shares of common stock may be sold in such states only through registered or licensed brokers or dealers. In addition,
in some states the shares of common stock may not be sold unless such shares have been registered or qualified for sale in such state
or an exemption from registration or qualification is available and is complied with.

 

There can be no assurance
that any selling stockholder will sell any or all of the shares of common stock registered pursuant to the registration statement, of
which this prospectus forms a part.

 

     

     

    

 

The selling stockholders and
any other person participating in such distribution will be subject to applicable provisions of the Securities Exchange Act of 1934, as
amended, and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the
timing of purchases and sales of any of the shares of common stock by the selling stockholders and any other participating person. Regulation
M may also restrict the ability of any person engaged in the distribution of the shares of common stock to engage in market-making activities
with respect to the shares of common stock. All of the foregoing may affect the marketability of the shares of common stock and the ability
of any person or entity to engage in market-making activities with respect to the shares of common stock.

 

We will pay all expenses of
the registration of the shares of common stock pursuant to the registration rights agreement, estimated to be $[     ]
in total, including, without limitation, Securities and Exchange Commission filing fees and expenses of compliance with state securities
or “blue sky” laws; provided, however, that a selling stockholder will pay all underwriting discounts and selling commissions,
if any. We will indemnify the selling stockholders against liabilities, including some liabilities under the Securities Act, in accordance
with the registration rights agreements, or the selling stockholders will be entitled to contribution. We may be indemnified by the selling
stockholders against civil liabilities, including liabilities under the Securities Act, that may arise from any written information furnished
to us by the selling stockholder specifically for use in this prospectus, in accordance with the related registration rights agreement,
or we may be entitled to contribution.

 

Once sold under the registration
statement, of which this prospectus forms a part, the shares of common stock will be freely tradable in the hands of persons other than
our affiliates.
