The Company further acknowledges that none of the Investors are acting as a financial advisor or fiduciary of the Company (or in
any similar capacity) with respect to the Transaction Documents and the transactions contemplated hereby and thereby and any advice
given by any of the Investors or any of their respective representatives or agents in connection with the Transaction Documents
and the transactions contemplated hereby and thereby is merely incidental to such Investor's purchase of the Purchase Shares. The
Company further represents to each of the Investors 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 and advisors.

 

(j)            No
Integrated Offering. Neither the Company, nor or any of its affiliates, nor any Person acting on their behalf has, directly
or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would
cause this offering of the Purchase Shares to be integrated with prior offerings by the Company in a manner that would require
stockholder approval pursuant to the rules of the Principal Market on which any of the securities of the Company are listed
or designated. The issuance and sale of the Purchase Shares hereunder does not contravene the rules and regulations of the
Principal Market.

(k)            Intellectual
Property Rights. The Company and its Subsidiaries own or possess adequate rights or licenses to use all material trademarks,
trade names, service marks, service mark registrations, service names, patents, patent rights, copyrights, inventions, licenses,
approvals, governmental authorizations, trade secrets and rights necessary to conduct their respective businesses as now conducted.
None of the Company's material trademarks, trade names, service marks, service mark registrations, service names, patents, patent
rights, copyrights, inventions, licenses, approvals, government authorizations, trade secrets or other intellectual property rights

licenses, service names, service marks, service mark registrations, trade secret or other similar rights of others, or of any such
development of similar or identical trade secrets or technical information by others, and there is no claim, action or proceeding
being made or brought against, or to the Company's knowledge, being threatened against, the Company or its Subsidiaries regarding
trademark, trade name, patents, patent rights, invention, copyright, license, service names, service marks, service mark registrations,
trade secret or other infringement, which could reasonably be expected to have a Material Adverse Effect.

 

(l)            Environmental

wastes, pollutants or contaminants (“Environmental Laws”), (ii) have received all permits, licenses or
other approvals required of them under applicable Environmental Laws to conduct their respective businesses and (iii) are
in compliance with all terms and conditions of any such permit, license or approval, except where, in each of the three foregoing

Except as set forth in the SEC Documents, the Company and its Subsidiaries have good and marketable title in fee simple to all

of the Company and its Subsidiaries, in each case free and clear of all liens, encumbrances and defects (“Liens”)
and, except for Liens as do not materially affect the value of such property and do not materially interfere with the use made
and proposed to be made of such property by the Company and its Subsidiaries and Liens for the payment of federal, state or other
taxes, the payment of which is neither delinquent nor subject to penalties.  Any real property and facilities held under
lease by the Company and its Subsidiaries are held by them under valid, subsisting and enforceable leases with which the Company
and its Subsidiaries are in compliance with such exceptions as are not material and do not interfere with the use made and proposed
to be made of such property and buildings by the Company and its Subsidiaries.

 

(n)            Insurance.
The Company and each of its Subsidiaries are 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 such Subsidiary has been refused any insurance coverage sought or
applied for and neither the Company nor any such Subsidiary has any reason to believe that it will not be able 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 materially and adversely affect the condition, financial or otherwise, or the earnings,
business or operations of the Company and its Subsidiaries, taken as a whole.

 

(o)            Regulatory
Permits. The Company and its Subsidiaries possess all material certificates, authorizations and permits issued by the appropriate
federal, state or foreign regulatory authorities necessary to conduct their respective businesses, and neither the Company nor

(p)            Tax
Status. Except for matters that would not, individually or in the aggregate, have or reasonably be expected to result in a
Material Adverse Effect, the Company and each of its Subsidiaries has made or filed all federal and state income and all other
material tax returns, reports and declarations required by any jurisdiction to which it is subject (unless and only to the extent
that the Company and each of its Subsidiaries has set aside on its books provisions reasonably adequate for the payment of all
unpaid and unreported taxes) and has paid all taxes and other governmental assessments and charges that are material in amount,
shown or determined to be due on such returns, reports and declarations, except those being contested in good faith and has set
aside on its books provision reasonably adequate for the payment of all taxes for periods subsequent to the periods to which such

action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any
distribution under a rights agreement) or other similar anti-takeover provision under the Certificate of Incorporation or the laws
of the state of its incorporation which is or could become applicable to any of the Investors as a result of the transactions contemplated
by this Agreement, including, without limitation, the Company's issuance of the Purchase Shares and the Investors' ownership of
the Purchase Shares.

 

(s)            Disclosure.  Except
with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents that will be timely
publicly disclosed by the Company, the Company confirms that neither it nor any other Person acting on its behalf has provided

and agrees that none of the Investors makes or has made any representations or warranties with respect to the transactions contemplated
hereby other than those specifically set forth in Section 3 hereof and, in that case, only with respect to such Investor and
not with respect to any other Investor.

(t)             Foreign
Corrupt Practices.  Neither the Company, nor to the knowledge
of the Company, any agent or other Person acting on behalf of the Company, has (i) directly or indirectly, used any funds
for unlawful contributions, gifts, entertainment or other unlawful expenses related to foreign or domestic political activity,
(ii) made any unlawful payment to foreign or domestic government officials or employees or to any foreign or domestic political

any Person acting on its behalf of which the Company is aware) which is in violation of law, or (iv) violated in any material
respect any provision of the Foreign Corrupt Practices Act of 1977, as amended.

 

(u)            Registration
Statement. The Company has prepared and filed with the SEC in accordance with the provisions of the Securities Act the Registration
Statement. The Registration Statement was declared effective by order of the SEC on May 18, 2020. The Registration Statement
is effective pursuant to the Securities Act and available for the issuance of the Purchase Shares thereunder, and the Company has
not received any written notice that the SEC has issued or intends to issue a stop order or other similar order with respect to
the Registration Statement or the Prospectus or that the SEC otherwise has (i) suspended or withdrawn the effectiveness of
the Registration Statement or (ii) issued any order preventing or suspending the use of the Prospectus or any Prospectus Supplement,
in either case, either temporarily or permanently or intends or has threatened in writing to do so. The “Plan of Distribution”
section of the Prospectus permits the issuance of the Purchase Shares under the terms of this Agreement. At the time the Registration
Statement and any amendments thereto became effective, at the date of this Agreement and at each deemed effective date thereof
pursuant to Rule 430B(f)(2) of the Securities Act, the Registration Statement and any amendments thereto complied and
will comply in all material respects with the requirements of the Securities Act and did not and will not contain any untrue statement
of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein
not misleading; and the Base Prospectus and any Prospectus Supplement thereto, at the time such Base Prospectus or such Prospectus
Supplement thereto was issued and on the Closing Date, complied and will comply in all material respects with the requirements
of the Securities Act and did not and will not contain an untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided
that this representation and warranty does not apply to statements in or omissions from any Prospectus Supplement made in reliance
upon and in conformity with information relating to the Investor furnished to the Company in writing by or on behalf of the Investor
expressly for use therein. The Company meets all of the requirements for the use of a registration statement on Form S-3 pursuant
to the Securities Act for the offering and sale of the Purchase Shares contemplated by this Agreement in reliance on General Instruction
I.B.1. of Form S-3, and the SEC has not notified the Company of any objection to the use of the form of the Registration Statement
pursuant to Rule 401(g)(1) of the Securities Act. The Company hereby confirms that the issuance of the Purchase Shares
to the Investor pursuant to this Agreement would not result in non-compliance with the Securities Act or any of the General Instructions
to Form S-3. The Registration Statement, as of its effective date, meets the requirements set forth in Rule 415(a)(1)(x) pursuant
to the Securities Act. At the earliest time after the filing of the Registration Statement that the Company or another offering
participant made a bona fide offer (within the meaning of Rule 164(h)(2) of the Securities Act) relating to any of the
Purchase Shares, the Company was not and is not an Ineligible Issuer (as defined in Rule 405 of the Securities Act). The Company
has not distributed any offering material in connection with the offering and sale of any of the Purchase Shares, and, until none
of the Investors hold any of the Purchase Shares, shall not distribute any offering material in connection with the offering and
sale of any of the Purchase Shares, to or by any of the Investors, in each case, other than the Registration Statement or any amendment
thereto, the Prospectus or any Prospectus Supplement required pursuant to applicable law or the Transaction Documents. The Company
has not made, and agrees that unless it obtains the prior written consent of each of the Investors it will not make, an offer relating
to the Purchase Shares that would constitute a “free writing prospectus” as defined in Rule 405 under the Securities
Act. The Company shall comply with the requirements of Rules 164 and 433 under the Securities Act applicable to any such free
writing prospectus consented to by each of the Investors, including in respect of timely filing with the SEC, legending and record
keeping.

the Company of the Purchase Shares contemplated by the Transaction Documents. Without limiting the generality of the foregoing,
neither the Company nor any of its officers, directors or affiliates will take, directly or indirectly, any action designed or
intended to stabilize or manipulate the price of any security of the Company, or which would reasonably be expected to cause or
result in, stabilization or manipulation of the price of any security of the Company.

 

(j)              Integration.
From and after the date of this Agreement, neither the Company, nor any of its affiliates will, and the Company shall use its reasonable
best efforts to ensure that no Person acting on any of their behalf will, directly or indirectly, make any offers or sales of any
security or solicit any offers to buy any security, under circumstances that would cause this offering of the Purchase Shares to
be integrated with other offerings of securities by the Company in a manner that would require stockholder approval pursuant to
the rules and regulations of the Principal Market on which any of the securities of the Company are listed or designated,
unless stockholder approval is obtained before the closing of such subsequent transaction in accordance with the rules of
such Principal Market.

 

(k)             Use
of Proceeds. The Company will use the net proceeds from the offering of the Purchase Shares as described in the Prospectus.

 

(l)             Variable
Rate Transactions. From and after the date of this Agreement until the fifth (5th) anniversary of the Closing Date,
without the prior written consent of the Lead Investor (which may be granted or withheld in its sole discretion), the Company shall
be prohibited from effecting or entering into an agreement to effect any issuance by the Company or any of its Subsidiaries of
Common Stock or Common Stock Equivalents (or a combination of units thereof) involving a Variable Rate Transaction. “Variable
Rate Transaction” means a transaction in which the Company (A) issues or sells any debt or equity securities that
are convertible into, exchangeable or exercisable for, or include the right to receive additional shares of Common Stock either
(1) at a conversion price, exercise price or exchange rate or other price that is based upon and/or varies with the trading
prices of or quotations for the shares of Common Stock at any time after the initial issuance of such debt or equity securities,
or (2) with a conversion, exercise or exchange price that is subject to being reset at some future date after the initial
issuance of such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly related
to the business of the Company or the market for the Common Stock or (B) enters into any agreement (including, without limitation,
an “equity line of credit”) with any Person, other than with the Lead Investor, whereby the Company or any Subsidiary
may sell securities at a future determined price. Notwithstanding the foregoing, beginning on the Trading Day immediately following
the last day of the Restricted Period (and in no event during the Restricted Period), the Company may sell shares of Common Stock
or Common Stock Equivalents in an “at- the-market offering” (as defined in Rule 415(a)(4) under the 1933
Act) through one or more registered broker-dealer(s). The Lead Investor shall be entitled to seek injunctive relief against the
Company and its Subsidiaries to preclude any such agreement, plan, arrangement or transaction, which remedy shall be in addition
to any right to collect damages, without the necessity of showing economic loss and without any bond or other security being required.

(m)           Participation
Right. From and after the date of this Agreement until the first (1st) anniversary of the Closing Date, and except underwritten
public offerings as set forth in clause (x) of this Section 5(m), the Company shall be prohibited from effecting or entering
into an agreement to effect any issuance by the Company or any of its Subsidiaries of Common Stock or Common Stock Equivalents
(or a combination of units thereof) for cash consideration (a “Subsequent Financing”), unless the Company shall
have first complied with this Section 5(m).

 

(i)           
Between 4:00 p.m. and 7:00 p.m., New York time, on the second (2nd) Business Day immediately preceding the Business
Day of a proposed or intended Subsequent Financing (each, a “Subsequent Financing Date”), the Company shall
deliver to the Lead Investor a written notice of its intention to effect a Subsequent Financing (each, a “Pre-Notice”)
(the Company shall use best efforts to ensure that the Lead Investor has received and acknowledged receipt of the Pre-Notice within
such time period), which Pre-Notice shall not contain any information (including, without limitation, material, non-public information)
other than: (x) a statement that the Company proposes or intends to effect a Subsequent Financing (without disclosing the
specific terms or conditions of the proposed Subsequent Financing or the securities to be offered and sold therein, (y) a
representation that such statement (described in clause (x) above) does not constitute material, non-public information regarding
the Company, its business or its securities and (z) a statement informing the Lead Investor that it is entitled to receive
a Subsequent Financing Notice (as defined below) containing material, non-public information with respect to such Subsequent Financing
upon its timely written request in accordance with this Section 5(m).

 

(ii)          
If the Lead Investor consents to receive material, non-public information with respect to such Subsequent Financing, the Lead Investor
shall deliver a written request therefor to the Company, not later than 9:00 a.m., New York time, on the Business Day immediately
preceding the Business Day of the proposed or intended Subsequent Financing, and upon such written request by the Lead Investor
delivered to the Company prior to such time, and only upon such written request by the Lead Investor, the Company shall promptly
thereafter, but not later than two (2) hours after such written request by the Lead Investor was properly delivered to the
Company, deliver to the Lead Investor a written notice of the proposed Subsequent Financing (a “Subsequent Financing Notice”),
which shall (A) describe in reasonable detail the proposed terms and conditions of such Subsequent Financing, including, without
limitation, the proposed terms of the securities to be offered and sold in such Subsequent Financing (the “Offered Securities”),
the total amount of proceeds intended to be raised and the Person or Persons through or with whom such Subsequent Financing is
proposed to be effected, (B) include, as an attachment thereto, a term sheet or similar document setting forth the material
terms and conditions of such Subsequent Financing, including, without limitation, the material terms of the Offered Securities,
and (C) offer to issue and sell to the Lead Investor, upon the terms and subject to the conditions of the Subsequent Financing
set forth in the Subsequent Financing Notice, 50% of the Offered Securities (the “Participation Maximum”) at
the same price per Offered Security to be paid by each other Person participating in such Subsequent Financing.

 

    -17-

     

    

 

(iii)         
In the event that the Lead Investor elects to participate in such Subsequent Financing for all or any part of the Participation
Maximum, the Lead Investor must deliver a written notice to the Company prior to the later of (i) 11:00 a.m., New York time,
on the Business Day on which such proposed or intended Subsequent Financing shall occur as set forth in the Subsequent Financing
Notice and (ii) two (2) hours after the time that the applicable Subsequent Financing Notice is received by the Lead
Investor (the “Notice Termination Time”), setting forth: (A) a statement that the Lead Investor elects
to participate in such Subsequent Financing, (B) the amount of Offered Securities, which shall not exceed the Participation
Maximum, that the Lead Investor elects to purchase in such Subsequent Financing, and (C) a representation that the Lead Investor
has sufficient funds available to purchase such Offered Securities in such Subsequent Financing on the terms and subject to the
conditions set forth in the applicable Subsequent Financing Notice received by the Lead Investor (the “Notice of Acceptance”).
If the Company does not receive a Notice of Acceptance from the Lead Investor prior to the applicable Notice Termination Time,
the Lead Investor shall be deemed to have elected not to participate in the Subsequent Financing on the terms set forth in the
applicable Subsequent Financing Notice received by the Lead Investor.

 

(iv)         
Notwithstanding the foregoing, if the Company desires to change, modify or amend any of the terms or conditions of a Subsequent
Financing, or the Offered Securities to be sold therein, set forth in a Subsequent Financing Notice delivered to the Lead Investor
hereunder, the Company shall promptly, but not later than 10:00 p.m., New York time, on the Business Day immediately preceding
the Business Day on which such Subsequent Financing is intended to occur, deliver to the Lead Investor a new written Subsequent
Financing Notice describing in reasonable detail the terms and conditions of such Subsequent Financing and Offered Securities,
as amended, and the Lead Investor will again have the right to participate in such Subsequent Financing upon the terms and conditions,
as amended, set forth in such new Subsequent Financing Notice, provided the Lead Investor delivers to the Company a Notice of Acceptance
providing the information described in the penultimate sentence of Section 5(m)(iii) above, prior to the Notice Termination
Time with respect to such new Subsequent Financing Notice, which shall be the later of (I) 11:00 a.m., New York time, on the
Business Day on which such proposed Subsequent Financing providing for such amended terms and conditions as set forth in the new
Subsequent Financing Notice delivered to the Lead Investor hereunder is intended to occur and (II) two (2) hours after
the time that such new Subsequent Financing Notice was received by the Lead Investor. If by the Notice Termination Time, the Lead
Investor has delivered to the Company a Notice of Acceptance in which it has elected to purchase in such Subsequent Financing an
aggregate amount of Offered Securities that is greater than the Participation Maximum, the Lead Investor shall be deemed to have
elected to participate for the applicable Participation Maximum in the Subsequent Financing on the terms set forth in the applicable
Subsequent Financing Notice received by the Lead Investor.

 

    -18-

     

    

 

(v)          
If by the Notice Termination Time, the Lead Investor has elected to purchase in such Subsequent Financing an aggregate amount of
Offered Securities that is equal to or less than the Participation Maximum, as reflected in an Acceptance Notice delivered by the
Lead Investor to the Company prior to the Termination Time, or the Lead Investor has not elected to participate in such Subsequent
Financing, then the Company may (A) offer, issue and sell all or any part of such Offered Securities as to which a Notice
of Acceptance has not been given by the Lead Investor, including any Offered Securities the Lead Investor did not elect to purchase
pursuant to a Notice of Acceptance as part of the Participation Maximum (all such Offered Securities that are not designated in
a Notice of Acceptance as Offered Securities to be purchased by the Lead Investor in such Subsequent Financing, the “Other
Securities”), pursuant to a definitive agreement(s) (the “Subsequent Financing Agreement”), but
only to the offerees described in the Subsequent Financing Notice and only upon terms and conditions (including, without limitation,
unit prices and interest rates) that are not more favorable to the acquiring Person or Persons or less favorable to the Company
than those set forth in the most recent Subsequent Financing Notice received by the Lead Investor and (B) to publicly announce
(x) the execution of such Subsequent Financing Agreement, and (y) either (I) the consummation of the transactions
contemplated by such Subsequent Financing Agreement or (II) the termination of such Subsequent Financing Agreement, which
shall be filed with the SEC on a Current Report on Form 8-K with such Subsequent Financing Agreement and any documents contemplated
therein filed as exhibits thereto. If a definitive agreement containing the terms and conditions of such Subsequent Financing as
set forth in the Subsequent Financing Notice delivered to the Lead Investor is not entered into by the Company for any reason within
five (5) Business Days after the date the initial Subsequent Financing Notice for such Subsequent Financing was first delivered
to the Lead Investor hereunder, and to the extent that the Company determines to proceed with such Subsequent Financing, the Company
shall promptly, but not later than 10:00 p.m., New York time, on the Business Day immediately preceding the Business Day on which
such Subsequent Financing is intended to occur, deliver to the Lead Investor a new written Subsequent Financing Notice describing
in reasonable detail the terms and conditions of such Subsequent Financing and Offered Securities, as amended, and the Lead Investor
will again have the right to participate in such Subsequent Financing upon the terms and conditions, as amended, set forth in such
new Subsequent Financing Notice, provided the Lead Investor delivers to the Company a Notice of Acceptance providing the information
described in the penultimate sentence of Section 5(m)(iii) above, prior to the Notice Termination Time with respect to
such new Subsequent Financing Notice, which shall be the time period described in Section 5(m)(iv) above.

 

(vi)         
In the event the Company shall propose to sell less than all the Other Securities (any such sale to be in the manner and on the
terms specified in Section 5(m)(v) above), then the Lead Investor may, at its sole option and in its sole discretion,
reduce the number or amount of the Offered Securities specified in its Notice of Acceptance to an amount that shall be not less
than the number or amount of the Offered Securities that the Lead Investor elected to purchase pursuant to Section 5(m)(iii) above
multiplied by a fraction, (A) the numerator of which shall be the number or amount of Offered Securities the Company actually
proposes to issue, sell or exchange (including Offered Securities to be issued or sold to the Lead Investor pursuant to this Section 5(m) prior
to such reduction) and (B) the denominator of which shall be the original amount of the Offered Securities. In the event that
the Lead Investor so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company
may not issue, sell or exchange more than the reduced number or amount of the Offered Securities unless and until such securities
have again been offered to the Lead Investor in accordance with Section 5(m)(i) and (ii) above.

 

(vii)        
Upon the closing of the issuance, sale or exchange of all or less than all of the Other Securities, the Lead Investor shall acquire
from the Company, and the Company shall issue to the Lead Investor, the number or amount of Offered Securities specified in its
Notice of Acceptance, as reduced pursuant to Section 5(m)(vi) above if the Lead Investor has so elected, upon the terms
and conditions specified in the Subsequent Financing Agreement. The purchase by the Lead Investor of any Offered Securities is
subject in all cases to the preparation, execution and delivery by the Company and the Lead Investor of a separate purchase agreement
relating to such Offered Securities reasonably satisfactory in form and substance to the Lead Investor and its counsel. Any Offered
Securities not acquired by the Lead Investor or other Persons in accordance with this Section 5(m) may not be issued,
sold or exchanged until they are again offered to the Lead Investor under the procedures specified in this Section 5(m).

 

    -19-

     

    

 

(viii)      
The Company and the Lead Investor agree that if the Lead Investor elects to participate in the Subsequent Financing, without the
prior written consent of the Lead Investor (which may be granted or withheld in its sole discretion), neither the Subsequent Financing
Agreement with respect to such Subsequent Financing nor any other transaction documents related thereto (collectively, the “Subsequent
Financing Documents”) shall include any term or provision whereby the Lead Investor shall be required to agree to any
restrictions on trading as to any securities of the Company or be required to consent to any amendment to or termination of, or
grant any waiver, release or the like under or in connection with, any agreement previously entered into with the Company or any
instrument received from the Company.

 

(ix)         
Notwithstanding anything to the contrary in this Section 5(m) and unless otherwise agreed to by the Lead Investor, the
Company shall either confirm in writing to the Lead Investor that the transaction with respect to the Subsequent Financing has
been abandoned or shall publicly disclose its intention to issue the Offered Securities, in either case, in such a manner such
that the Lead Investor will not be in possession of any material, non-public information, by the fifth (5th) Business
Day following delivery of the Subsequent Financing Notice. If by such fifth (5th) Business Day, no public disclosure
regarding a transaction with respect to the Offered Securities has been made, and no notice regarding the abandonment of such transaction
has been received by the Lead Investor, such transaction shall be deemed to have been abandoned and the Lead Investor shall not
be in possession of any material, non-public information with respect to the Company or any of its Subsidiaries. Should the Company
decide to pursue such transaction with respect to the Offered Securities, the Company shall provide the Lead Investor with another
Subsequent Financing Notice and the Lead Investor will again have the right of participation set forth in this Section 5(m).

 

(x)          
The restrictions contained in this Section 5(m) shall not apply in connection with the issuance of any Common Stock or
Common Stock Equivalents (or a combination of units thereof) in a firm commitment underwritten public offering of Common Stock
or Common Stock Equivalents (or a combination of units thereof).

 

(n)            Other
Transactions. The Company shall not enter into, announce or recommend to its stockholders any agreement, plan, arrangement
or transaction in or of which the terms thereof would restrict, materially delay, conflict with or impair the ability or right
of the Company to perform its obligations under any of the Transaction Documents to which it is a party, including, without limitation,
the obligation of the Company to deliver the Purchase Shares to the Investors in accordance with the terms of this Agreement.

 

(o)            Investor
Lock-Up and Voting Agreement. Each Investor, severally and not jointly, hereby agrees that such Investor shall not, during
the period commencing on the date hereof and ending on the earlier of (i) the calendar day immediately following the date
established by the Company’s board of directors as the record date for the Company’s special meeting of stockholders
to be held on March 4, 2021 (the “Record Date”) and (ii) January 21, 2021 (the “Lock-Up
Period”), offer, pledge, sell, contract to sell, grant, lend, or otherwise transfer or dispose of, directly or indirectly,
any of the Purchase Shares set forth opposite such Investor’s name on Schedule I hereto that are being purchased by
such Investor hereunder. Each Investor, severally and not jointly, hereby agrees that such Investor and its affiliates shall vote
all of their shares of Common Stock, including all of the Purchase Shares being purchased by such Investor hereunder, beneficially
owned by such Investor and its affiliates on the Record Date and entitled to vote at the special meeting to be held on March 4,
2021 in favor of each Company proposal that is submitted by the Company to its stockholders for a vote at the special meeting.

6.             TRANSFER
AGENT INSTRUCTIONS.

 

On the Closing Date,
the Company shall issue to the Transfer Agent (and any subsequent transfer agent) irrevocable instructions, in the form heretofore
furnished to the Company, to issue the Purchase Shares in accordance with the terms of this Agreement (the “Irrevocable
Transfer Agent Instructions”). All Purchase Shares to be issued to or for the benefit of the Investors pursuant to this
Agreement shall be issued as DWAC Shares. The Company represents and warrants to each of the Investors that no instruction other
than the Irrevocable Transfer Agent Instructions referred to in this Section 6 will be given by the Company to the Transfer
Agent with respect to the Purchase Shares, and the Purchase Shares shall otherwise be freely transferable on the books and records
of the Company. Certificates and any other instruments evidencing the Purchase Shares shall not bear any restrictive or other legend.
If any Investor effects a sale, assignment or transfer of the Purchase Shares, the Company shall permit the transfer and shall
promptly instruct the Transfer Agent (and any subsequent transfer agent) to issue DWAC Shares in such name and in such denominations
as specified by such Investor to effect such sale, transfer or assignment. The Company acknowledges that a breach by it of its
obligations hereunder will cause irreparable harm to the Investors. Accordingly, the Company acknowledges that the remedy at law
for a breach of its obligations under this Section 6 will be inadequate and agrees, in the event of a breach or threatened
breach by the Company of the provisions of this Section 6, that each of the Investors shall be entitled, in addition to all
other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without
the necessity of showing economic loss and without any bond or other security being required. The Company shall take all actions
to carry out the intent and accomplish the purposes of this Section 6, including, without limitation, delivering or causing
to be delivered all such legal opinions, consents, certificates, resolutions and instructions to the Transfer Agent (and any subsequent
transfer agent) to the extent required or requested by the Transfer Agent (or any subsequent transfer agent) or as necessary or
desirable to carry out the intent and accomplish the purposes of this Section 6. Any fees (with respect to the Transfer Agent,
counsel to the Company or otherwise) associated with the issuance of such legal opinions, consents, certificates, resolutions and
instructions shall be borne by the Company.

use in the Initial Prospectus Supplement), if the Prospectus was timely made available by the Company to such Investor pursuant
to Section 5(l), (III) the indemnity contained in clauses (d), (e) and (f) of this Section 9 shall not
inure to the benefit of an Investor to the extent such Indemnified Liabilities are based on a failure of such Investor to deliver
or to cause to be delivered the Prospectus made available by the Company, if such Prospectus was timely made available by the Company
pursuant to Section 5(l), and if delivery of the Prospectus by such Investor was required under the Securities Act with respect
to the Purchase Shares and such delivery by such Investor would have cured the defect giving rise to such Indemnified Liabilities,
and (IV) the indemnity in this Section 9 shall not apply to amounts paid in settlement of any claim if such settlement
is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld, conditioned or
delayed. 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 which is permissible under applicable
law. Any required indemnification payment for any particular claim shall be made within thirty (30) days from the date an Investor
makes a written request for it. A certificate containing reasonable detail as to the amount of such indemnification submitted to
the Company by an Investor shall be conclusive evidence, absent manifest error, of the amount due from the Company to such Investor.
If any action shall be brought against any Indemnitee in respect of which indemnity may be sought pursuant to this Agreement, such
Indemnitee shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with
counsel of its own choosing reasonably acceptable to the Indemnitee. Any Indemnitee shall have the right to employ separate counsel
in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of
such Indemnitee, except to the extent that (i) the employment thereof has been specifically authorized by the Company in writing,
(ii) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (iii) in
such action there is, in the reasonable opinion of such separate counsel, a material conflict on any material issue between the
position of the Company and the position of such Indemnitee, in which case the Company shall be responsible for the reasonable
fees and expenses of no more than one such separate counsel.

11.          TERMINATION

 

This Agreement may
be terminated only as follows:

 

(a)           If
pursuant to or within the meaning of any Bankruptcy Law, the Company commences a voluntary case or any Person commences a proceeding
against the Company, a Custodian is appointed for the Company or for all or substantially all of its property, or the Company makes
a general assignment for the benefit of its creditors, this Agreement shall automatically terminate without any liability or payment
to the Company (except as set forth below) without further action or notice by any Person.

 

(b)           In
the event that the Closing shall not have occurred on or before January 15, 2021, due to the failure to satisfy the conditions
set forth in Sections 7 and 8 above with respect to the Closing, either the Company, on the one hand, or any Investor, on the other
hand, shall have the option to terminate this Agreement at the close of business on such date or thereafter without liability of
any party to any other party (except as set forth below); provided, however, that the right to terminate this Agreement under this
Section 11(b) shall not be available to any party if such party is then in breach of any covenant or agreement contained
in this Agreement or any representation or warranty of such party contained in this Agreement fails to be true and correct such
that the conditions set forth in Section 7(c) or Section 8(d), as applicable, could not then be satisfied. Any termination
of this Agreement pursuant to this Section 11(b) shall be effected by written notice from the Company to each of the
Investors, or any Investor to the Company and each of the other Investors, as the case may be, setting forth the basis for the
termination hereof.

 

The representations and warranties and
covenants of the Company and the Investors contained in Sections 3, 4, 5, and 6 hereof, the indemnification provisions set forth
in Section 9 hereof and the agreements and covenants set forth in Sections 10, 11 and 12, shall survive the Closing and any
termination of this Agreement. No termination of this Agreement shall be deemed to release the Company or any Investor from any
liability for intentional misrepresentation or willful breach by such party of any of the Transaction Documents to which it is
a party.

 

    -25-

     

    

 

12.          MISCELLANEOUS.

 

(a)           Governing
Law; Jurisdiction; Jury Trial. The corporate laws of the State of Delaware shall govern all issues concerning the relative
rights of the Company and its stockholders. All other questions concerning the construction, validity, enforcement and interpretation
of this Agreement and the other Transaction Documents shall be governed by the internal laws of the State of Illinois, without
giving effect to any choice of law or conflict of law provision or rule (whether of the State of Illinois or any other jurisdictions)
that would cause the application of the laws of any jurisdictions other than the State of Illinois. Each party hereby irrevocably
submits to the exclusive jurisdiction of the state and federal courts sitting in the State of Illinois, County of Cook, for the
adjudication of any dispute hereunder or under the other Transaction Documents or in connection herewith or therewith, or with
any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action
or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding
is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably
waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy
thereof to such party at the address for such notices to it under this Agreement and the other Transaction Documents and agrees
that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be
deemed to limit in any way any right to serve process in any manner permitted by law. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY
RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION
HEREWITH OR ARISING OUT OF THIS AGREEMENT OR ANY OF THE OTHER TRANSACTION DOCUMENTS OR ANY TRANSACTION CONTEMPLATED HEREBY OR THEREBY.

 

(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
signature or signature delivered by e-mail in a “.pdf” format data file, including any electronic signature complying
with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com, www.echosign.adobe.com, etc., 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 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.

 

(d)           Severability.
If any provision of this Agreement shall be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall
not affect the validity or enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability
of any provision of this Agreement in any other jurisdiction.

 

(e)           Entire
Agreement; Amendment. This Agreement and the other Transaction Documents supersede all other prior oral or written agreements
among the Investors, the Company, their respective affiliates and Persons acting on their behalf with respect to the subject matter
hereof, and this Agreement, the other Transaction Documents and the instruments referenced herein 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 of the Investors makes any representation, warranty, covenant or undertaking with respect to such matters.
The Company acknowledges and agrees that is has not relied on, in any manner whatsoever, any representations or statements, written
or oral, other than as expressly set forth in the Transaction Documents. No provision of this Agreement or the other Transaction
Documents may be amended other than by a written instrument signed by each of the parties hereto or thereto.

(g)           Successors
and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and any permitted successors and
assigns of the Company. The Company shall not assign this Agreement or any rights or obligations hereunder without the prior written
consent of each of the Investors, including by merger or consolidation. None of the Investors may assign its rights or obligations
under this Agreement.

 

(h)           No
Third Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and any permitted successors and
assigns of the Company and, except as set forth in Section 9, is not for the benefit of, nor may any provision hereof be
enforced by, any other Person.

 

(i)            Publicity.
The Company shall afford each of the Investors and its counsel with the opportunity to review and comment upon the form and substance
of, and shall give reasonable consideration to all such comments from such Investor or its counsel on, any press release, SEC filing
or any other public disclosure by or on behalf of the Company relating to such Investor, its purchases hereunder or any aspect
of the Purchase Shares, any of the Transaction Documents or the transactions contemplated thereby, not less than 24 hours prior
to the issuance, filing or public disclosure thereof. Each Investor must be provided with a final version of any such press release,
SEC filing or other public disclosure at least 24 hours prior to any release, filing or use by the Company thereof. The Company
agrees and acknowledges that its failure to fully comply with this provision constitutes a Material Adverse Effect. Except as contemplated
in Section 5(f) hereof, no Investor shall issue a press release or any other public disclosure regarding this Agreement
or the substance hereof without the prior written consent of the Company, which consent shall not be unreasonably withheld, conditioned
or delayed.

 

(j)            Further
Assurances. Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall
execute and deliver all such other agreements, certificates, instruments and documents, as the other party may reasonably request
in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated
hereby.

 

(k)            No
Financial Advisor, Placement Agent, Broker or Finder. The Company represents and warrants to each of the Investors that it
has not engaged any financial advisor, placement agent, broker or finder in connection with the transactions contemplated hereby.
Each Investor, severally and only with respect to itself and not jointly, represents and warrants to the Company that it has not
engaged any financial advisor, placement agent, broker or finder in connection with the transactions contemplated hereby. The Company
shall be responsible for the payment of any fees or commissions, if any, of any financial advisor, placement agent, broker or finder
relating to or arising out of the transactions contemplated hereby. The Company shall pay, and hold each of the Investors harmless
against, any liability, loss or expense (including, without limitation, attorneys' fees and out of pocket expenses) arising in
connection with any such claim.

 

(l)             No
Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express
their mutual intent, and no rules of strict construction will be applied against any party.

 

(m)          Remedies,
Other Obligations, Breaches and Injunctive Relief. The Investors’ remedies provided in this Agreement, including, without
limitation, the Investors’ remedies provided in Section 9, shall be cumulative and in addition to all other remedies
available to the Investors under this Agreement, at law or in equity (including a decree of specific performance and/or other injunctive
relief), no remedy of any of the Investors contained herein shall be deemed a waiver of compliance with the provisions giving rise
to such remedy and nothing herein shall limit any Investor's right to pursue actual damages for any failure by the Company to comply
with the terms of this Agreement. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable
harm to the Investors and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the
event of any such breach or threatened breach, any Investor shall be entitled, in addition to all other available remedies, to
an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being
required.

 

    -28-

     

    

 

 

(n)           Enforcement
Costs. If: (i) this Agreement is placed by any Investor in the hands of an attorney for enforcement or is enforced by
any Investor through any legal proceeding; (ii) an attorney is retained to represent any Investor in any bankruptcy, reorganization,
receivership or other proceedings affecting creditors' rights and involving a claim under this Agreement; or (iii) an attorney
is retained to represent any Investor in any other proceedings whatsoever in connection with this Agreement, then the Company shall
pay to such Investor, as incurred by such Investor, all reasonable costs and expenses including attorneys' fees incurred in connection
therewith, in addition to all other amounts due hereunder. If this Agreement is placed by the Company in the hands of an attorney
for enforcement against an Investor or is enforced by the Company against an Investor through any legal proceeding, then such Investor
against whom this Agreement is so enforced shall pay to the Company, as incurred by the Company, all reasonable costs and expenses
including reasonable attorneys’ fees incurred in connection therewith, in addition to all other amounts due hereunder.

 

(o)           Waivers.
No provision of this Agreement may be waived other than in a written instrument signed by the party against whom enforcement of
such waiver is sought. No failure or delay in the exercise of any power, right or privilege hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof
or of any other right, power or privilege.

 

(p)           Independent
Nature of Investors’ Obligations and Rights. The obligations of each Investor under the Transaction Documents are several
and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of
the obligations of any other Investor under any Transaction Document. Nothing contained herein or in any other Transaction Document,
and no action taken by any Investor pursuant hereto or thereto, shall be deemed to constitute the Investors as, and the Company
acknowledges that the Investors do not so constitute, a partnership, an association, a joint venture or any other kind of group
or entity, or create a presumption that the Investors are in any way acting in concert or as a group or entity with respect to
such obligations or the transactions contemplated by the Transaction Documents or any matters, and the Company acknowledges that
the Investors are not 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. The decision of each Investor to purchase Purchase Shares pursuant
to the Transaction Documents has been made by such Investor independently of any other Investor. Each Investor acknowledges that
no other Investor has acted as agent for such Investor in connection with such Investor making its investment hereunder and that
no other Investor will be acting as agent of such Investor in connection with monitoring such Investor’s investment in the
Purchase Shares or enforcing its rights under the Transaction Documents. The Company and each Investor confirms that each Investor
has independently participated with the Company in the negotiation of the transaction contemplated hereby with the advice of its
own counsel and advisors. Each Investor 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
Investor to be joined as an additional party in any proceeding for such purpose. The use of a single agreement to effectuate the
purchase and sale of the Purchase Shares contemplated hereby was solely in the control of the Company, not the action or decision
of any Investor, and was done solely for the convenience of the Company and not because it was required or requested to do so by
any Investor. It is expressly understood and agreed that each provision contained in this Agreement and in each other Transaction
Document is between the Company and an Investor, solely, and not between the Company and the Investors collectively and not between
and among the Investors.

 

    -29-

     

    

 

(q)           Counsel
to Lead Investor. It is expressly understood and agreed by the Company and each of the Investors that Dorsey & Whitney
LLP has acted as counsel and has rendered legal advice only to the Lead Investor, and not to the Company, any other Investor or
any other Person in connection with the transactions contemplated by the Transaction Documents, and that each of the Company and
each Investor other than the Lead Investor has relied for such matters on the advice of its own respective legal counsel.

 

(r)            Expenses.
The Company has agreed to pay the Lead Investor the following: (i) $50,000 upon the signing of the term sheet relating to
this Agreement, and (ii) $50,000 upon the signing of this Agreement, as the full and complete expense reimbursement of the
Lead Investor’s expenses in connection with the transaction contemplated hereby, including any due diligence expenses and
legal fees.
