Exhibit 10.1


 


COMMON
STOCK PURCHASE AGREEMENT


 


COMMON
STOCK PURCHASE AGREEMENT (the “Agreement”), dated as of April 27, 2020 by and between SORRENTO
THERAPEUTICS, INC., a Delaware corporation (the “Company”), and Arnaki Ltd., a British Virgin Islands
corporation (including its successors and assigns, the “Purchaser”).  Capitalized terms used herein and
not otherwise defined herein are defined in Section 10 hereof.


 


WHEREAS:


 


Subject to
the terms and conditions set forth in this Agreement, the Company wishes to sell to the Purchaser, and the Purchaser wishes to
buy from the Company, up to Two Hundred and Fifty Million Dollars ($250,000,000) of the Company’s common stock, par value
$0.0001 per share (the “Common Stock” or “Securities”).  The shares of Common Stock
to be purchased hereunder are referred to herein as the “Purchase Shares.”


 


NOW THEREFORE,
the Company and the Purchaser hereby agree as follows:


 


1.                                   PURCHASE
OF COMMON STOCK.


 


Subject to
the terms and conditions set forth in this Agreement, the Company has the right to sell to the Purchaser, and the Purchaser has
the obligation to purchase from the Company, Purchase Shares as follows:


 


(a)                                 Commencement
of Purchases of Common Stock.  Any time after Commencement (as defined below), the purchase and sale of Purchase Shares
hereunder may occur from time to time upon written notices by the Company to the Purchaser on the terms and conditions as set
forth herein following the satisfaction of the conditions (the “Commencement”) as set forth in Sections 6 and
7 below (the date of satisfaction of such conditions, the “Commencement Date”).


 


(b)                                 Fixed
and Optional Purchases.  Subject to the terms and conditions of this Agreement, on any given Business Day from
and after the Commencement Date and during the Facility Term, the Company
shall have the right but not the obligation to (i) direct the Purchaser by its delivery to the Purchaser of a Purchase Notice,
substantially in the form attached hereto as Exhibit A, from time to
time, and the Purchaser thereupon shall have the obligation, subject to Section 1(d), to buy the number of Purchase Shares specified
in such notice, up to 650,000 Purchase Shares on such Business Day (the “Fixed Request Amount”), and/or (ii)
at the Company’s sole discretion, grant the Purchaser an option to buy an additional amount of shares (the “Optional
Purchase,” collectively with the Fixed Request Amount, a “Regular Purchase”) at the Purchase Price
per Purchase Share on the Purchase Date. The Company and the Purchaser may mutually agree to increase the number of Purchase Shares
for the Fixed Request Amount to as much as an additional 3,600,000 Purchase Shares on a Purchase Date.  In
consideration of and in express reliance upon the representations, warranties and covenants, and otherwise upon the terms and
subject to the conditions, of this Agreement, from and after the Commencement Date and
during the Facility Term (i) the Company shall issue and sell to the Purchaser, and the Purchaser agrees to purchase from the
Company, the Purchase Shares in respect of each Fixed Request Amount and (ii) the Purchaser may in its discretion elect to purchase
Purchase Shares in respect of each Optional Purchase.  The issuance and sale of Purchase Shares to the Purchaser pursuant
to any Fixed Request Amount or Optional Purchase shall occur on the applicable Settlement Date in accordance with Section 1(i),
provided that all of the conditions precedent thereto set forth in Section 7 theretofore shall have been fulfilled or (to the
extent permitted by applicable law) waived.


 


The share
amounts in this Section 1(b) shall be appropriately adjusted for any reorganization, recapitalization, non-cash dividend,
stock split, reverse stock split or other similar transaction.


 


(c)                                 Payment
for Purchase Shares.  For each Regular Purchase, the Purchaser shall pay to the Company an amount equal to the Purchase
Amount as full payment for such Purchase Shares via wire transfer of immediately available funds on the same Business Day that
the Purchaser receives such Purchase Shares.  All payments made under this Agreement shall be made in lawful money of the
United States of America via wire transfer of immediately available funds to such account as the Company may from time to time
designate by written notice in accordance with the provisions of this Agreement.  Whenever any amount expressed to be due
by the terms of this Agreement is due on any day that is not a Business Day, the same shall instead be due on the next succeeding
day that is a Business Day.


 






     

     


    

 


(d)                                  Purchase
Price Floor.  The Purchaser shall have the right but not the obligation to purchase any Purchase Shares at the Floor
Price on any Purchase Date where either (i) the VWAP is less than the Floor Price or (ii) the Purchase Price is less than the
Floor Price. “Floor Price” means $1.10 per share of Common Stock, which shall not be adjusted for any reorganization,
recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction. If
trading in the Common Stock on the Principal Market is suspended for any reason for more than three (3) hours on the applicable
Purchase Date (which, for the avoidance of doubt, shall not include any reduced trading hours scheduled in advance by the Principal
Market, such as days surrounding or including holidays where the Principal Market closes at 1:00 PM Eastern Time), the Purchaser
may, at its option, purchase any Purchase Shares on such Purchase Date at a price
per Purchase Share that is equal to the greater of (i) the Purchase Price on such Purchase Date and (ii) the Floor Price.
For each Purchase Date that has reduced trading hours scheduled in advance by the Principal Market, the total amount of the Fixed
Request Amount shall be reduced proportionally (for example, on the days surrounding or including holidays where the Principal
Market closes at 1:00 PM Eastern Time, the total amount of the Fixed Request Amount shall be reduced by 40%).  


 


(e)                                   Records
of Purchases.  The Purchaser and the Company shall each maintain records showing the remaining Available Amount at any
given time and the dates and Purchase Amounts for each purchase, or shall use such other method reasonably satisfactory to the
Purchaser and the Company to reconcile the remaining Available Amount.


 


(f)                                  Taxes. 
The Company shall pay any and all transfer, stamp or similar taxes that may be payable with respect to the issuance and delivery
of any shares of Common Stock to the Purchaser made under this Agreement.


 


(g)                                 Compliance
with Principal Market Rules.  Notwithstanding anything in this Agreement to the contrary, and in addition to the limitations
set forth in Section 1(h), the total number of shares of Common Stock that may be issued under this Agreement shall be limited
to 41,917,130 shares of Common Stock (the “Exchange Cap”), which equals 19.99% of the Company’s outstanding
shares of Common Stock as of the date hereof, unless stockholder approval is obtained to issue more than such 19.99%.  The
Exchange Cap shall be appropriately adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse
stock split or other similar transaction.  The foregoing limitation shall not apply if stockholder approval has not been
obtained and at any time the Exchange Cap is reached and at all times thereafter the average price paid for all shares of Common
Stock issued under this Agreement is equal to or greater than $2.37 (the “Minimum Price”), a price equal to
the lower of (1) the Closing Sale Price immediately preceding the execution of this Agreement or (2) the arithmetic
average of the five (5) Closing Sale Prices for the Common Stock immediately preceding the execution of this Agreement (in
such circumstance, for purposes of the Principal Market, the transaction contemplated hereby would not be “below market”
and the Exchange Cap would not apply). The Minimum Price shall be appropriately adjusted for any reorganization, recapitalization,
non-cash dividend, stock split, reverse stock split or other similar transaction.  Notwithstanding the foregoing, the Company
shall not be required or permitted to issue, and the Purchaser shall not be required to purchase, any shares of Common Stock under
this Agreement if such issuance would breach the Company’s obligations under the rules or regulations of the Principal
Market.  The Company may, in its sole discretion, determine whether to obtain stockholder approval to issue more than 19.99%
of its outstanding shares of Common Stock hereunder if such issuance would require stockholder approval under the rules or
regulations of the Principal Market.


 


(h)                                     Beneficial
Ownership Limitation. The Company shall not issue, and the Purchaser shall not purchase any shares of Common Stock under this
Agreement, if such shares proposed to be issued and sold, when aggregated with all other shares of Common Stock then owned beneficially
(as calculated pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended (the “1934 Act”)
and Rule 13d-3 promulgated thereunder) by the Purchaser and its affiliates would result in the beneficial ownership by the
Purchaser and its affiliates of more than 4.99% of the then issued and outstanding shares of Common Stock.


 


(i)                                     Settlement.
The Purchaser shall deliver to the Company, via facsimile transmission or e-mail in accordance
with this Section 1(i), not later than 8:00 p.m. (New York time) on the Purchase Date, a Purchaser Confirmation, substantially
in the form attached hereto as Exhibit B (the “Purchaser Confirmation”), which shall specify
(i) the total Fixed Request Amount to be purchased by the Purchaser on the applicable Settlement Date, (ii) the Purchase Price
at which the Purchaser will purchase the Purchase Shares pursuant to the Purchase Notice, (iii) the total number of Purchase Shares,
if any, to be purchased by the Purchaser in respect of the applicable Fixed Request Amount, and (iv) the total amount of the Optional
Purchase, if applicable, to be purchased by the Purchaser on the applicable Settlement Date. The payment for, against subsequent
delivery of, Purchase Shares in respect of each Regular Purchase shall be settled on the second Business Day next following the
Purchase Date, or on such earlier date as the parties may mutually agree (the “Settlement Date”).  On
each Settlement Date, the Company shall, or shall cause its transfer agent to, electronically transfer the Purchase Shares purchased
by the Purchaser by crediting the Purchaser’s or its designee(s) account at DTC through its Deposit/Withdrawal at Custodian
(DWAC) system, which Purchase Shares shall be freely tradable and transferable and without restriction on resale, against simultaneous
payment therefor to the Company’s designated account by wire transfer of immediately available funds. 


 






     

     


    

 


(j)                                     Failure
to Deliver. If the Company issues a Purchase Notice and fails to deliver the Purchase
Shares to the Purchaser on the applicable Settlement Date, subject to simultaneous payment, and such failure continues for five
(5) Business Days, the Company shall pay the Purchaser, in cash (or, at the option of the Purchaser, in shares of Common Stock
valued at the applicable Purchase Price of the Purchase Shares failed to be delivered; provided that the issuance thereof by the
Company would not violate the Securities Act or any applicable U.S. federal or state securities laws), as partial damages for
such failure and not as a penalty, an amount equal to 2.0% of the payment required to be paid by the Purchaser on such Settlement
Date (i.e., the sum of the Fixed Request Amount and the Optional Purchase) for the initial thirty (30) days following such Settlement
Date until the Purchase Shares have been delivered, and an additional 2.0% for each additional 30-day period thereafter until
the Purchase Shares have been delivered, which amount shall be prorated for such periods less than thirty (30) days. Nothing in
this Section 1(j) shall be deemed to release the Company from any liability for any breach under this Agreement, or to impair
the rights of the Purchaser to compel specific performance by the Company of its obligations under this Agreement. 


 


(k)                                     Purchase
Notice. Upon the terms and subject to the conditions of this Agreement, the Purchaser is obligated to accept each Purchase
Notice prepared and delivered in accordance with the provisions of this Agreement. A valid
Purchase Notice must be delivered on or before 2:00 p.m. (New York time) on the Purchase Date specified in the Purchase Notice; provided, however,
that with respect to the Purchase Notice received after 9:30 a.m. (New York time) but on or before 2:00 p.m. (New York time) (the
 “Intraday Notice”), the total amount of the Fixed Request Amount shall
be reduced proportionally by 1/13th for each half-hour between 9:30 a.m. (New York time) and
the time at which the Purchase Notice is delivered (for example, if the Intraday Notice is received by the Purchaser at 11:00
a.m. (New York time), the total amount of the Fixed Request Amount shall be reduced
by 3/13 or 150,000 shares).


 


For
the avoidance of doubt, all calculations with respect to the timing of the Intraday Notice shall be rounded up to the nearest
half-hour (for example, 12:10 p.m. (New York time) would
be rounded to 12:30 p.m. (New York time)). All calculations with respect to Purchase
Price of the Intraday Notice shall be based on the intraday VWAP commencing from one minute after the timestamp on the Purchaser’s
receipt of an e-mail (or any equivalent means of communication mutually agreed by the Purchaser and the Company) that contains
a Purchase Notice, or such other time mutually agreed by the Purchaser and the Company, until 4:00 p.m. (New York time).


 


If the Company
delivers the Purchase Notice to the Purchaser later than 2:00 p.m. (New York time) on a Purchase Date, then the Purchase Date
shall not be the Business Day on which the Purchaser received such Purchase Notice, but rather shall be the next Business Day
(unless a subsequent Business Day is therein specified).

representations and warranties contained in Section 3 below.  The Purchaser has sought such accounting, legal and tax
advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Securities.

(f)                                   SEC
Documents; Financial Statements. Except as disclosed in Schedule 3(f), since December 31, 2019, the Company has filed all
reports, schedules, forms, statements and other documents required to be filed by it with the SEC pursuant to the reporting requirements
of the 1934 Act (all of the foregoing filed prior to the date hereof and all exhibits included therein and financial statements
and schedules thereto and documents incorporated by reference therein being hereinafter referred to as the “SEC Documents”). 
As of their respective dates (except as they have been correctly amended), the SEC Documents complied in all material respects
with the requirements of the 1934 Act and the rules and regulations of the SEC promulgated thereunder applicable to the SEC
Documents, and none of the SEC Documents, at the time they were filed with the SEC (except as they may have been properly amended),
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 light of the circumstances under which they were made, not misleading.  As of
their respective dates (except as they have been properly amended), the financial statements of the Company included in the SEC
Documents complied as to form in all material respects with applicable accounting requirements and the published rules and
regulations of the SEC with respect thereto.  Such financial statements have been prepared in accordance with generally accepted
accounting principles, consistently applied, during the periods involved (except (i) as may be otherwise indicated in such
financial statements or the notes thereto or (ii) in the case of unaudited interim statements, to the extent they may exclude
footnotes or may be condensed or summary statements) and fairly present in all material respects the financial position of the
Company as of the dates thereof and the results of its operations and cash flows for the periods then ended (subject, in the case
of unaudited statements, to normal year-end audit adjustments).  Except as disclosed in Schedule 3(f) or routine correspondence,
such as comment letters and notices of effectiveness in connection with previously filed registration statements or periodic reports
publicly available on EDGAR, to the Company’s knowledge, the Company or any of its Subsidiaries are not on the date hereof
the subject of any inquiry, investigation or action by the SEC.


 






     

     


    

 


(g)                                    Absence
of Certain Changes.  Except as disclosed in Schedule 3(g), since December 31, 2019, there has been no material adverse
change in the business, properties, operations, financial condition or results of operations of the Company or its Subsidiaries
taken as a whole.  For purposes of this Agreement, neither a decrease in cash or cash equivalents or in the market price
of the Common Stock nor losses incurred in the ordinary course of the Company’s business shall be deemed or considered a
material adverse change.  The Company has not taken any steps, and does not currently expect to take any steps, to seek protection
pursuant to any Bankruptcy Law nor does the Company or any of its Subsidiaries have any knowledge or reason to believe that its
creditors intend to initiate involuntary bankruptcy or insolvency proceedings.  The Company is financially solvent and is
generally able to pay its debts as they become due.


 


(h)                                    Absence
of Litigation. Except as disclosed in Schedule 3(h), to the Company’s knowledge, there is no action, suit, proceeding,
inquiry or investigation before or by any court, public board, government agency, self-regulatory organization or body pending
or, to the knowledge of the Company or any of its Subsidiaries, threatened against the Company, the Common Stock or any of the
Company’s Subsidiaries or any of the Company’s or the Company’s Subsidiaries’ officers or directors in
their capacities as such, which could reasonably be expected to have a Material Adverse Effect (each, an “Action”). 
A description of each such Action, if any, is set forth in Schedule 3(h).


 


(i)                                     Acknowledgment
Regarding Purchaser’s Status.  The Company acknowledges and agrees that the Purchaser is acting solely in the capacity
of arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated hereby and thereby. 
The Company further acknowledges that the Purchaser is not 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 the Purchaser or any of its representatives or agents in connection with the Transaction Documents and the transactions
contemplated hereby and thereby is merely incidental to the Purchaser’s purchase of the Securities.  The Company further
represents to the Purchaser 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)                                     Intellectual
Property Rights.  To the Company’s knowledge, 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 other intellectual property
rights (collectively, “Intellectual Property”) necessary to conduct their respective businesses as now conducted,
except as set forth in Schedule 3(j) or to the extent that the failure to own, possess, license or otherwise hold adequate
rights to use Intellectual Property would not, individually or in the aggregate, have a Material Adverse Effect.  Except
as disclosed in Schedule 3(j), to the Company’s knowledge, none of the Company’s active and registered Intellectual
Property have expired or terminated, or, by the terms and conditions thereof, will expire or terminate within two years from the
date of this Agreement, except as would not reasonably be expected to have a Material Adverse Effect.  The Company and its
Subsidiaries do not have any knowledge of any infringement by the Company or its Subsidiaries of any Intellectual Property of
others and, except as set forth on Schedule 3(j), 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 Intellectual Property, which
could reasonably be expected to have a Material Adverse Effect.


 






     

     


    

 


(k)                                     Environmental
Laws.  To the Company’s knowledge, the Company and its Subsidiaries (i) are in material compliance with any
and all applicable foreign, federal, state and local laws and regulations relating to the protection of human health and safety
or the environment and with respect to hazardous or toxic substances or wastes, pollutants or contaminants (“Environmental
Laws”), (ii) have received all material permits, licenses or other approvals required of them under applicable
Environmental Laws to conduct their respective businesses and (iii) are in material compliance with all terms and conditions
of any such permit, license or approval, except where, in each of the three foregoing clauses, the failure to so comply or receive
such approvals could not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.


 


(l)                                     Title. 
The Company and its Subsidiaries have good and marketable title to all personal property owned by them that is material to the
business of the Company and its Subsidiaries, in each case free and clear of all liens, encumbrances and defects except such as
are described in Schedule 3(l) or 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 and any of its Subsidiaries or could not reasonably be expected
to have, individually or in the aggregate, a Material Adverse Effect.  Any real property and facilities held under lease
by the Company and any of its Subsidiaries, to the Company’s knowledge, are held by them 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 and its Subsidiaries.


 


(m)                                    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 reasonable and customary in the businesses in which the
Company and its Subsidiaries are engaged.  To the Company’s knowledge, since January 1, 2019, 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,
to the Company’s knowledge, 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 reasonably
be expected to have a Material Adverse Effect.


 


(n)                                    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 as currently conducted,
except when the failure to so possess such certificates, authorizations or permits could not reasonably be expected to have, individually
or in the aggregate, a Material Adverse Effect, and neither the Company nor any such Subsidiary has received any written notice
of proceedings relating to the revocation or modification of any such material certificate, authorization or permit.


 


(o)                                    Tax
Status.  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 reserves reasonably adequate for the payment of all unpaid
and unreported taxes or filed valid extensions) 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 reserves reasonably adequate for the payment of all taxes for periods subsequent to the periods
to which such returns, reports or declarations apply.  To the Company’s knowledge, there are no unpaid taxes in any
material amount claimed to be due by the taxing authority of any jurisdiction.


 


(p)                                    Transactions
With Affiliates.  Except as set forth on Schedule 3(p), and other than (i) the grant or exercise of stock options
or any other equity securities offered pursuant to duly adopted stock or incentive compensation plans as disclosed on Schedule
3(c) and (ii) employment or indemnification agreements approved by the Board of Directors of the Company, none of the
officers, directors or employees of the Company is on the date hereof a party to any transaction with the Company or any of its
Subsidiaries (other than for services as employees, officers and directors and reimbursement for expenses incurred on behalf of
the Company), including any contract, agreement or other arrangement providing for the furnishing of services to or by, providing
for rental of real or personal property to or from, or otherwise requiring payments to or from any officer, director or such employee
or, to the knowledge of the Company, any corporation, partnership, trust or other entity in which any officer, director, or any
such employee has a material interest or is an officer, director, trustee or general partner.


 






     

     


    

 


(q)                                    Application
of Takeover Protections.  The Company and its board of directors have taken or will take prior to the Commencement Date
all necessary 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, other than Section 203 of the General Corporation Law of the State of Delaware,
which is or could become applicable to the Purchaser as a result of the transactions contemplated by this Agreement, including,
without limitation, the Company’s issuance of the Securities and the Purchaser’s ownership of the Securities.


 


(r)                                     Registration
Statement.  The Shelf Registration Statement (as defined in Section 4(a) hereof) has been declared effective
by the SEC, and no stop order has been issued or is pending or, to the knowledge of the Company, threatened by the SEC with respect
thereto.  As of the date hereof, the Company has a dollar amount of securities registered and unsold under the Shelf Registration

4.                                      COVENANTS.


 


(a)                                     Filing
of Form 8-K and Prospectus Supplement.  The Company agrees that it shall, within the time required under the 1934
Act, file a Current Report on Form 8-K disclosing this Agreement and the transaction contemplated hereby (the “Form
8-K”). The Company shall use its reasonable best efforts to keep the existing shelf registration statement on Form S-3
(File No. 333-237142) (the “Shelf Registration Statement”) effective pursuant to Rule 415 promulgated
under the 1933 Act and available for sales of all Securities to the Purchaser until such time as (i) it no longer qualifies
to make sales under the Shelf Registration Statement (which shall be understood to include the inability of the Company to immediately
effectuate sales of Securities to the Purchaser under the Shelf Registration Statement pursuant to General Instruction I.B.1 of
Form S-3), (ii) the date on which all the Securities have been sold under this Agreement and no Available Amount remains
thereunder, or (iii) this Agreement has been terminated.  The Shelf Registration Statement (including any amendments
or supplements thereto and prospectuses or prospectus supplements contained therein) shall not contain any untrue statement of
a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading


 


(b)                                     Blue
Sky. The Company shall take such action, if any, as is reasonably necessary in order to obtain an exemption for or to qualify
(i) the initial sale of the Securities to the Purchaser under this Agreement and (ii) any subsequent sale of the Securities
by the Purchaser, in each case, under applicable securities or “Blue Sky” laws of the states of the United States
in such states as is reasonably requested by the Purchaser from time to time, and shall provide evidence of any such action so
taken to the Purchaser at its written request; provided, however, that the Company shall not be obligated to
file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction
in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it
is not otherwise so subject.


 


(c)                                     Listing. 
The Company shall promptly secure the listing of all of the Securities upon each national securities exchange and automated quotation
system that requires an application by the Company for listing, if any, upon which shares of Common Stock are then listed (subject
to official notice of issuance) and shall maintain such listing, so long as any other shares of Common Stock shall be so listed. 
The Company shall use its reasonable best efforts to maintain the Common Stock’s listing on the Principal Market. 
Neither the Company nor any of its Subsidiaries shall take any action that would be reasonably expected to result in the delisting
or suspension of the Common Stock on the Principal Market, unless the Common Stock is immediately thereafter traded on the New
York Stock Exchange, the NYSE American, the Nasdaq Global Select Market, the Nasdaq Global Market, or the Nasdaq Capital Market. 
The Company shall pay all fees and expenses in connection with satisfying its obligations under this Section.


  


(d)                                    Due
Diligence.  The Purchaser shall have the right, from time to time as the Purchaser may reasonably request, to perform
reasonable due diligence on the Company during normal business hours and subject to reasonable prior notice to the Company. 
The Company and its officers and employees shall provide information and reasonably cooperate with the Purchaser in connection
with any reasonable request by the Purchaser related to the Purchaser’s due diligence of the Company, including, but not
limited to, any such request made by the Purchaser in connection with the Commencement; provided, however, that at no time is
the Company required to disclose material nonpublic information to the Purchaser or breach any obligation of confidentiality or
non-disclosure to a third party or make any disclosure that could cause a waiver of attorney-client privilege.  Except as
may be required by law, court order or governmental authority, each party hereto agrees not to disclose any Confidential Information
of the other party to any third party and shall not use the Confidential Information of such other party for any purpose other
than in connection with, or in furtherance of, the transactions contemplated hereby; provided, that to the extent such disclosure
is required by law, court order or governmental authority, the receiving party shall provide the disclosing party with reasonable
prior written notice of such disclosure and make a reasonable effort to assist the disclosing party in obtaining a protective
order preventing or limiting the disclosure and/or requiring that the Confidential Information so disclosed be used only for the
purposes for which the law, court order or governmental authority requires.  Each party hereto acknowledges that the Confidential
Information shall remain the property of the disclosing party and agrees that it shall take all reasonable measures to protect
the secrecy of any Confidential Information disclosed by the other party.


 






     

     


    

 


(e)                                     Selling
Restrictions.  (i)  Except as expressly set forth below, the Purchaser covenants that from and after the date hereof
through and including the termination of this Agreement (the “Restricted Period”), neither the Purchaser nor
any of its affiliates nor any entity managed or controlled by the Purchaser (collectively, the “Restricted Persons”
and each of the foregoing is referred to herein as a “Restricted Person”) shall, directly or indirectly, (x)
engage in any Short Sales (as defined in Rule 200 promulgated under Regulation SHO under
the Exchange Act) involving the Company’s securities or (y) grant any option to purchase, or acquire any right to
dispose of or otherwise dispose for value of, any shares of Common Stock or any securities convertible into or exercisable or
exchangeable for any shares of Common Stock, or enter into any swap, hedge or other similar agreement that transfers, in whole
or in part, the economic risk of ownership of the Common Stock or establishes a net short position with respect to the Common
Stock. Notwithstanding the foregoing, it is expressly understood and agreed that nothing contained herein shall (without implication
that the contrary would otherwise be true) prohibit any Restricted Person during the Restricted Period from:  (1) selling
 “long” (as defined under Rule 200 promulgated under Regulation SHO) any shares of Common Stock; or (2) selling a number
of shares of Common Stock equal to (x) the number of shares of Common Stock that such Restricted Person is or may be obligated
to purchase under a pending Fixed Request Amount and/or (y) the number of shares of Common Stock that such Restricted Person may
purchase under a pending Optional Purchase, but, in each case, has not yet taken possession of so long as such Restricted Person
(or a broker-dealer of such Restricted Person, as applicable) delivers the Purchase Shares purchased pursuant to such Fixed Request
Amount and/or Optional Purchase to the purchaser thereof or the applicable broker-dealer; provided, however,
such Restricted Person (or the applicable broker-dealer, as applicable) shall not be required to so deliver any such shares of
Common Stock subject to such Fixed Request Amount or Optional Purchase, as the case may be, if (a) such Fixed Request Amount or
Optional Purchase, as the case may be, is terminated by mutual agreement of the Company and the Purchaser and, as a result of
such termination, no such shares of Common Stock are delivered to the Purchaser under this Agreement or (b) the Company otherwise
fails to deliver such shares of Common Stock to the Purchaser on the applicable Settlement Date upon the terms and subject to
the provisions of this Agreement.


 


(ii) In
addition to the foregoing, in connection with any sale of Securities (including any sale permitted by Section 4(e)(i) above),
the Purchaser shall comply in all respects with all applicable laws, rules, regulations and orders, including, without limitation,
the requirements of the Securities Act and the Exchange Act.


  


5.                                      TRANSFER
AGENT INSTRUCTIONS.


 


All of the
Purchase Shares to be issued under this Agreement shall be issued without any restrictive legend unless the Purchaser expressly
consents otherwise.  The Company shall issue irrevocable instructions to the Transfer Agent, and any subsequent transfer
agent, to issue Common Stock in the name of the Purchaser for the Purchase Shares (the “Irrevocable Transfer Agent Instructions”). 
The Company warrants to the Purchaser that no instruction other than the Irrevocable Transfer Agent Instructions referred to in
this Section 5, will be given by the Company to the Transfer Agent with respect to the Purchase Shares and that the Purchase
Shares shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement.

captioned “The Transaction” and “Plan of Distribution”, and (C) with respect to the prospectus,
the foregoing indemnity shall not inure to the benefit of the Purchaser or any such Person from whom the Person asserting any
loss, claim, damage, liability or expense purchased Common Stock, if copies of all prospectus supplements required to be filed
pursuant to Section 7(l), together with the base prospectus, were timely delivered or made available to the Purchaser pursuant
hereto and a copy of the base prospectus, together with a prospectus supplement (as applicable), was not sent or given by or on
behalf of the Purchaser or any such Person to such Person, if required by law to have been delivered, at or prior to the written
confirmation of the sale of the Common Stock to such Person, and if delivery of the base prospectus, together with a prospectus
supplement (as applicable), would have cured the defect giving rise to such loss, claim, damage, liability or expense.


 






     

     


    

 


The Company
shall reimburse the Purchaser and each such director, officer, partner, employee, agent, representative and affiliate or controlling
Person promptly upon demand (with accompanying presentation of documentary evidence) for all legal and other costs and expenses
reasonably incurred by the Purchaser or such indemnified Persons in investigating, defending against, or preparing to defend against
any such claim, action, suit or proceeding with respect to which it is entitled to indemnification.


 


(b)                                     Indemnification
by the Purchaser.  The Purchaser shall indemnify and hold harmless the Company, each of its directors, officers, partners,
employees, agents, representatives and affiliates, and each Person, if any, who controls the Company within the meaning of Section
15 of the Securities Act or Section 20(a) of the Exchange Act from and against all losses, claims, damages, liabilities and expenses
(including reasonable and documented costs of defense and investigation and all reasonable and documented attorneys’ fees)
to which the Company and each such other Person may become subject, under the Securities Act or otherwise, insofar as such losses,
claims, damages, liabilities and expenses arise out of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in the Form 8-K, the Shelf Registration Statement or any prospectus supplement or free writing prospectus,
or any amendment thereof or supplement thereto, or the omission or alleged omission to state therein any material fact required
to be stated therein or necessary to make the statements therein, in light of the circumstances under which the statements therein
were made, not misleading, in each case, to the extent, and only to the extent, that such untrue statement, alleged untrue statement,
omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by
or on behalf of the Purchaser expressly for use in the Form 8-K or any prospectus supplement or free writing prospectus, or any
amendment thereof or supplement thereto, including, without limitation, the information set forth on Exhibit C hereto for
inclusion in the Prospectus Supplement in the sections captioned “The Transaction” and “Plan of Distribution”
or updated from time to time in writing by the Purchaser and furnished to the Company by the Purchaser expressly for inclusion
in the Form 8-K, the Shelf Registration Statement a prospectus or any new registration statement or from the failure of the Purchaser
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 this Agreement.


 


The Purchaser
shall reimburse the Company and each such director, officer, partner, employee, agent, representative and affiliate or controlling
Person promptly upon demand (with accompanying presentation of documentary evidence) for all legal and other costs and expenses
reasonably incurred by the Company or such indemnified Persons in investigating, defending against, or preparing to defend against
any such claim, action, suit or proceeding with respect to which it is entitled to indemnification.


 






     

     


    

 


(c)                                      Promptly
after a Person receives notice of a claim or the commencement of an action for which the Person intends to seek indemnification
under Section 8(a) or (b), the Person will notify the indemnifying party in writing of the claim or commencement of the action,
suit or proceeding; provided, however, that failure to notify the indemnifying party will not relieve
the indemnifying party from liability under Section 8(a) or (b), except to the extent it has been materially prejudiced by the
failure to give notice.  The indemnifying party will be entitled to participate in the defense of any claim, action, suit
or proceeding as to which indemnification is being sought, and if the indemnifying party acknowledges in writing the obligation
to indemnify the party against whom the claim or action is brought, the indemnifying party may (but will not be required to) assume
the defense against the claim, action, suit or proceeding with counsel satisfactory to it.  After an indemnifying party notifies
an indemnified party that the indemnifying party wishes to assume the defense of a claim, action, suit or proceeding, the indemnifying
party will not be liable for any legal or other expenses incurred by the indemnified party in connection with the defense against
the claim, action, suit or proceeding except that if, in the opinion of counsel to the indemnifying party, one or more of the
indemnified parties should be separately represented in connection with a claim, action, suit or proceeding, the indemnifying
party will pay the reasonable fees and expenses of one separate counsel for the indemnified parties.  Each indemnified party,
as a condition to receiving indemnification as provided in Section 8(a) or (b), will cooperate in all reasonable respects with
the indemnifying party in the defense of any action or claim as to which indemnification is sought.  No indemnifying party
will be liable for any settlement of any action effected without its prior written consent.  Notwithstanding the foregoing
sentence, if at any time an indemnified party shall have requested (by written notice provided in accordance with Section 11(f))
an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that
it shall be liable for any settlement of the nature contemplated hereby effected without its written consent if (i) such settlement
is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party
shall have received written notice of the terms of such settlement at least 30 days prior to such settlement being entered into
and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the
date of such settlement.  No indemnifying party will, without the prior written consent of the indemnified party, effect
any settlement of a pending or threatened action with respect to which an indemnified party is, or is informed that it may be,
made a party and for which it would be entitled to indemnification, unless the settlement includes an unconditional release of
the indemnified party from all liability and claims which are the subject matter of the pending or threatened action.


 


If
for any reason the indemnification provided for in this Agreement is not available to, or is not sufficient to hold harmless,
an indemnified party in respect of any loss or liability referred to in Section 8(a) or (b) as to which such indemnified party
is entitled to indemnification thereunder, each indemnifying party shall, in lieu of indemnifying the indemnified party, contribute
to the amount paid or payable by the indemnified party as a result of such loss or liability, (i) in the proportion which is appropriate
to reflect the relative benefits received by the indemnifying party, on the one hand, and by the indemnified party, on the other
hand, from the sale of Securities which is the subject of the claim, action, suit or proceeding which resulted in the loss or
liability or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause (i) above, but also the relative fault of the indemnifying party,
on the one hand, and the indemnified party, on the other hand, with respect to the statements or omissions which are the subject
of the claim, action, suit or proceeding that resulted in the loss or liability, as well as any other relevant equitable considerations.


 


The
remedies provided for in Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available
to any indemnified Person at law or in equity.


 


9.                                      EVENTS
OF DEFAULT.


 


An “Event
of Default” shall be deemed to have occurred at any time as any of the following events occurs:


 


(a)                                    during
any period in which the effectiveness of any registration statement is required to be maintained pursuant to the terms of this
Agreement, the effectiveness of such registration statement lapses for any reason (including, without limitation, the issuance
of a stop order) or is unavailable to the Company for the sale of all of the Purchase Shares to the Purchaser, and such lapse
or unavailability continues for a period of ten (10) consecutive Business Days or for more than an aggregate of thirty (30)
Business Days in any 365-day period, which is not in connection with a post-effective amendment to any such registration statement
or the filing of a new registration statement; provided, however, that in connection with any post-effective amendment to such
registration statement or filing of a new registration statement that is required to be declared effective by the SEC, such lapse
or unavailability may continue for a period of no more than thirty (30) consecutive Business Days, which such period shall be
extended for an additional thirty (30) Business Days if the Company receives a comment letter from the SEC in connection therewith;


 






     

     


    

 


(b)                                 the
suspension from trading or failure of the Common Stock to be listed on a Principal Market for a period of three (3) consecutive
Business Days;


 


(c)                                  the
delisting of the Common Stock from the Principal Market, and the Common Stock is not immediately thereafter trading on the New
York Stock Exchange, the NYSE American, the Nasdaq Global Select Market, the Nasdaq Global Market, or the Nasdaq Capital Market;


 


(d)                                 the
failure for any reason by the Transfer Agent to issue Purchase Shares to the Purchaser after the applicable
Settlement Date that the Purchaser is entitled to receive, and such failure continues
for five (5) Business Days;


 


(e)                                  the
Company’s breach of any representation or warranty (as of the dates made), covenant or other term or condition under any
Transaction Document if such breach could reasonably be expected to have a Material Adverse Effect and except, in the case of
a breach of a covenant which is reasonably curable, only if such breach continues uncured for a period of at least five (5) Business
Days;


 


(f)                                   if
any Person commences a proceeding against the Company pursuant to or within the meaning of any Bankruptcy Law;


 


(g)                                  if
the Company pursuant to or within the meaning of any Bankruptcy Law; (A) commences a voluntary case, (B) consents to
the entry of an order for relief against it in an involuntary case, (C) consents to the appointment of a Custodian of it
or for all or substantially all of its property, (D) makes a general assignment for the benefit of its creditors or (E) becomes
insolvent;


 


(h)                                   a
court of competent jurisdiction enters an order or decree under any Bankruptcy Law that (A) is for relief against the Company
in an involuntary case, (B) appoints a Custodian of the Company or for all or substantially all of its property, or (C) orders
the liquidation of the Company or any Subsidiary; or


 


(i)                                    if
at any time after the Commencement Date, the Exchange Cap is reached unless and until stockholder approval has been obtained pursuant
to Section 1(h) hereof.  The Exchange Cap shall be deemed to be reached at such time if, upon submission of a Purchase
Notice under this Agreement, the issuance of such shares of Common Stock would exceed the number of shares of Common Stock which
the Company may issue under this Agreement without breaching the Company’s obligations under the rules or regulations
of the Principal Market.


 


In addition to any other rights
and remedies under applicable law and this Agreement, including the Purchaser termination rights under Section 11(k) hereof,
so long as an Event of Default has occurred and is continuing, or if any event which, after notice and/or lapse of time, would
become an Event of Default, has occurred and is continuing, or so long as the VWAP is below the Floor Price, the Company may not
require and the Purchaser shall not be obligated to purchase any shares of Common Stock under this Agreement.  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, (any of which would be an Event of Default as described in Sections 9(f),
9(g) and 9(h) hereof) this Agreement shall automatically terminate without any liability or payment to the Company without
further action or notice by any Person.  No such termination of this Agreement under Section 11(k)(i) shall affect
the Company’s or the Purchaser’s obligations under this Agreement with respect to pending purchases and the Company
and the Purchaser shall complete their respective obligations with respect to any pending purchases under this Agreement.

(k)                                  Termination. 
This Agreement may be terminated only as follows:


 


(i)                                     By
the Purchaser any time an Event of Default exists without any liability or payment to the Company.  However, 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, (any of which would be an Event of Default as described in Sections 9(f),
9(g) and 9(h) hereof) this Agreement shall automatically terminate without any liability or payment to the Company without
further action or notice by any Person.  No such termination of this Agreement under this Section 11(k)(i) shall
affect the Company’s or the Purchaser’s obligations under this Agreement with respect to pending purchases and the
Company and the Purchaser shall complete their respective obligations with respect to any pending purchases under this Agreement.


 






     

     


    

 


(ii)                                  In
the event that the Commencement shall not have occurred the Company shall have the option to terminate this Agreement for any
reason or for no reason without any liability whatsoever of either party to the other party under this Agreement.


 


(iii)                                 In
the event that the Commencement shall not have occurred within ten (10) Business Days of the date of this Agreement, due
to the failure to satisfy any of the conditions set forth in Sections 6 and 7 above with respect to the Commencement, either party
shall have the option to terminate this Agreement at the close of business on such date or thereafter without liability of either
party to any other party; provided, however, that the right to terminate this Agreement under this Section 11(k)(iii) shall
not be available to either party if such failure to satisfy any of the conditions set forth in Sections 6 and 7 is the result
of a breach of this Agreement by such party or the failure of any representation or warranty of such party included in this Agreement
to be true and correct in all material respects.


 


(iv)                               
At any time after the Commencement Date, the Company shall have the option to terminate this Agreement for any reason or for no
reason by delivering notice (a “Company Termination Notice”) to the Purchaser electing to terminate this Agreement
without any liability whatsoever of either party to the other party under this Agreement.  The Company Termination Notice
shall not be effective until one (1) Business Day after it has been received by the Purchaser.


 


(v)                                 This
Agreement shall automatically terminate on the date that the Company sells and the Purchaser purchases the full Available Amount
as provided herein, without any action or notice on the part of any party and without any liability whatsoever of any party to
any other party under this Agreement.


 


(vi)                                If
by the conclusion of the Facility Term for any reason or for no reason the full Available Amount under this Agreement has not
been purchased as provided for in Section 1 of this Agreement, this Agreement shall automatically terminate on the date that
is 36 months from the Commencement Date, without any action or notice on the part of any party and without any liability whatsoever
of any party to any other party under this Agreement.


 


Except as set forth
in Sections 11(k)(i) (in respect of an Event of Default under Sections 9(f), 9(g) and 9(h)), 11(k)(v) and 11(k)(vi),
any termination of this Agreement pursuant to this Section 11(k) shall be effected by written notice from the Company
to the Purchaser, or the Purchaser to the Company, as the case may be, setting forth the basis for the termination hereof. 
The representations and warranties of the Company and the Purchaser contained in Sections 2, 3 and 5 hereof, the indemnification
provisions set forth in Section 8 hereof and the agreements and covenants set forth in Sections 4(e) and 11, shall survive
the Commencement and any termination of this Agreement.  No termination of this Agreement shall affect the Company’s
or the Purchaser’s rights or obligations under this Agreement with respect to pending purchases and the Company and
the Purchaser shall complete their respective obligations with respect to any pending purchases under this Agreement.


 


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


 






     

     


    

 


(m)                                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.


 


(n)                                 Failure
or Indulgence Not Waiver.  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.
