corrective actions with regard to significant deficiencies and material weaknesses; the principal executive officers (or their
equivalents) and principal financial officers (or their equivalents) of the Company have made all certifications required by the

shall be limited to one law firm serving as counsel for the Indemnified Parties) and other expenses incurred by it in connection
with investigating, preparing to defend or defending, or providing evidence in or preparing to serve or serving as a witness with
respect to, any lawsuit, investigation, claim or other proceeding relating to any of the foregoing, irrespective of whether the
transactions contemplated hereby are consummated, except to the extent such claim, damage, loss, liability, or expense is found
in a Final Order to have resulted from such Indemnified Party’s bad faith, actual fraud, gross negligence, or willful misconduct.
No Indemnified Party shall have any liability (whether direct or indirect, in contract, tort or otherwise) to the Company, for
or in connection with the transactions contemplated hereby, except to the extent such liability is found in a final, non-appealable
order of a court of competent jurisdiction to have resulted from such Indemnified Party’s bad faith, actual fraud, gross
negligence or willful misconduct. In no event, however, shall the Company or any Indemnified Party be liable on any theory of liability
for any special, indirect, consequential or punitive damages. Without the prior written consent of the Indemnified Parties, the
Company agrees that it will not enter into any settlement of any lawsuit, claim or other proceeding arising out of this Agreement,
the other Transaction Documents, or the transactions contemplated hereby or thereby, unless such settlement (i) includes an
explicit and unconditional release from the party bringing such lawsuit, claim or other proceeding of all Indemnified Parties and
(ii) does not include a statement as to or an admission of fault, culpability, or a failure to act by or on behalf of any
Indemnified Party. No Indemnified Party shall be liable for any damages arising from the use by unauthorized persons of any information
made available to the Indemnified Parties by the Company or representatives through electronic, telecommunications or other information
transmission systems that is intercepted by such persons. No Indemnified Party shall settle any lawsuit, claim, or other proceeding
arising out of this Agreement, the other Transaction Documents, or the transactions contemplated hereby or thereby without the
prior written consent of the Company (such consent not to be unreasonably withheld or delayed). Notwithstanding the foregoing,
an Indemnified Party shall be entitled to no indemnification by the Company for any claim, damage, loss, liability, or expense
incurred by or asserted or awarded against such Indemnified Party for (x) any violation of Law by such Indemnified Party, or (y)
to the extent that a claim, damage, loss, liability or expense is attributable to the Purchaser’s breach of any of the representations,
warranties, covenants or agreements made by the Purchaser in this Agreement or in the other Transaction Documents.


Section 10.      MISCELLANEOUS.


10.1     Payments.

10.2     Arm’s
Length Transaction. The Company acknowledges and agrees that (i) the Common Stock Equity Offering and any other transactions
described in this Agreement are an arm’s-length commercial transaction between the Parties and (ii) the Purchaser has
not assumed nor will it assume an advisory or fiduciary responsibility in the Company’s favor with respect to any of the
transactions contemplated by this Agreement or the process leading thereto, and the Purchaser has no obligation to the Company
with respect to the transactions contemplated by this Agreement except those obligations expressly set forth in this Agreement
or the Transaction Documents to which it is a party.


10.3     Survival.
The representations, warranties, covenants, agreements and obligations of the Parties shall survive the Closing as follows (each
such survival period, a “Survival Period”): (i) except for Fundamental Representations and the Tax Representations,
the representations and warranties made by each Party in this Agreement shall survive the Closing until the first anniversary of
the Closing; (ii) Fundamental Representations shall survive the Closing until the fifth anniversary of the Closing, (iii) Tax Representations
shall survive the Closing for the full period of all applicable statutes of limitations related thereto (after giving effect to
any waiver or extension thereof), and (iv) the covenants, agreements, obligations and other undertakings of the Parties shall survive
the Closing until fully performed in accordance with their terms. All liability of the Indemnifying Parties with respect to the
representations, warranties, covenants, agreements and obligations hereunder shall be extinguished at the end of the applicable
Survival Period, except to the extent that notice of an alleged breach of such representations, warranties, covenants, agreements
or obligations has been provided before such date; provided that if notice is given prior to the expiration of the applicable Survival
Period, the claim with respect to such representation, warranty, covenant, agreement or obligation shall continue indefinitely
until finally resolved.


10.4     No
Waiver of Rights. All waivers hereunder must be made in writing, and the failure of any Party at any time to require another
Party’s performance of any obligation under this Agreement shall not affect the right subsequently to require performance
of that obligation. Any waiver of any breach of any provision of this Agreement shall not be construed as a waiver of any continuing
or succeeding breach of such provision or a waiver or modification of any other provision.


10.5     Notices.
All notices, requests, claims, demands and other communications hereunder shall be in writing and shall be given or made (and shall
be deemed to have been duly given or made upon receipt) by delivery in person, by an internationally recognized overnight courier
service, by email or registered or certified mail (postage prepaid, return receipt requested) to the respective Parties at the
following addresses (or at such other address for any Party as shall be specified by such Party in a notice given in accordance
with this Section 10.5).

(b)        If
to the Purchaser, to the address set forth on Exhibit F.


Any of the foregoing addresses may be
changed by giving notice of such change in the foregoing manner, except that notices for changes of address shall be effective
only upon receipt.


10.6     Headings.
The section and subsection headings in this Agreement are inserted for convenience only and shall not affect in any way the meaning
or interpretation of this Agreement.


10.7     Severability.
If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy,
all other terms and provisions of this Agreement shall nevertheless remain in full force and effect for so long as the economic
or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon
such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate
in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable
manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.


10.8     Entire
Agreement. This Agreement and the agreements and documents referenced herein constitute the entire agreement of the Parties
with respect to the subject matter hereof and supersede all prior agreements and undertakings, both written and oral, between the
Parties with respect to the subject matter hereof.


10.9     Successors
and Assigns. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and
permitted assigns. Except as set forth below, neither this Agreement nor any of the rights, interests or obligations under this
Agreement may be assigned by either Party (whether by operation of law or otherwise) without the prior written consent of the other
Party. Notwithstanding the foregoing, the rights, obligations and interests hereunder may be assigned, delegated or transferred,
in whole or in part, by the Purchaser to (i) any Affiliate of the Purchaser upon notice to but without the consent of the Company
or (ii) one or more other third parties with the consent of the Company, which consent shall not be unreasonably withheld or delayed;
provided, however, that any such transferee, as a condition precedent to such transfer, becomes a Party to this Agreement
and assumes the obligations of the Purchaser with respect to the transferred shares under this Agreement by executing an addendum
substantially in the form set forth in Exhibit A (the “Addendum”) and an assumption agreement in
substantially the form set forth in Exhibit B hereto (the “Assumption Agreement”) and deliver the
same to the Company in accordance with Section 10.5, and provided, further, that (a) with respect to
a transfer to an Affiliate of the Purchaser, the Purchaser either (i) shall have provided an adequate equity support letter or
a guarantee of such Affiliate-transferee’s obligations, in form and substance reasonably acceptable to the Company or (ii)
shall remain fully obligated to fund the Purchase Price, and (b) with respect to a transfer to a third party, the Company, acting
in good faith, shall have consented in writing to such transfer (which consent shall not be unreasonably withheld, conditioned
or delayed) and shall have determined, in its reasonable discretion, after due inquiry and investigation, that such transferee
is reasonably capable of fulfilling such obligations, or, absent such a determination, the proposed transferee shall have deposited
with an agent of the Company or into an escrow account under arrangements satisfactory to the Company funds sufficient, in the
reasonable determination of the Company, to satisfy such proposed transferee’s obligations; and provided, further,
that in no event shall the Purchaser make an assignment of any of its rights, obligations or interests under this Agreement that,
to the Purchaser’s actual knowledge, would violate applicable Law. Any transfer that is made in violation of the immediately
preceding sentence shall be null and void ab initio, and the Company shall have the right to enforce the voiding of such transfer.

10.10      No
Third-Party Beneficiaries. This Agreement shall be binding upon and inure solely to the benefit of the Parties and their respective
successors and permitted assigns and, except as expressly set forth in Section 9, nothing herein, express or implied, is
intended to or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever.


10.11      Amendment.
This Agreement may not be altered, amended, or modified except by a written instrument executed by or on behalf of the Company
and the Purchaser.


10.12      Governing
Law. This Agreement shall be interpreted, construed and enforced in accordance with the laws of the State of Delaware, without
regard to the conflicts of law principles thereof.


10.13      Consent
to Jurisdiction. Each of the Parties (a) irrevocably and unconditionally agrees that any actions, suits or proceedings,
at law or equity, arising out of or relating to this Agreement or any agreements or transactions contemplated hereby shall be heard
and determined by the federal or state courts located in the State of Delaware; (b) irrevocably submits to the jurisdiction
of such courts in any such action, suit or proceeding; (c) consents that any such action, suit or proceeding may be brought
in such courts and waives any objection that such Party may now or hereafter have to the venue or jurisdiction of such courts or
that such action or proceeding was brought in an inconvenient forum; and (d) agrees that service of process in any such action,
suit or proceeding may be effected by providing a copy thereof by any of the methods of delivery permitted by Section 10.5
to such Party at its address as provided in Section 10.5 (provided that nothing herein shall affect the right to effect
service of process in any other manner permitted by Law).


10.14      Waiver
of Jury Trial. EACH OF THE PARTIES HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY
HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT
OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT, OR ANY OTHER THEORY). EACH OF THE PARTIES HERETO HEREBY
(A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH
OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE
OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE TRANSACTIONS, AS APPLICABLE, BY, AMONG OTHER THINGS,
THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.14.






    	 	35 	 



     


    

 


10.15      Currency.
Unless otherwise specified in this Agreement, all references to currency, monetary values and dollars set forth herein shall mean
United States (U.S.) dollars and all payments hereunder shall be made in United States dollars.


10.16      Counterparts.
This Agreement may be executed and delivered (including by facsimile or electronic transmission) in one or more counterparts, and
by the different Parties in separate counterparts, each of which when executed shall be deemed to be an original, but all of which
taken together shall constitute one and the same agreement. Signatures of the Parties transmitted by electronic mail shall be deemed
to be their original signatures for all purposes.


10.17      Specific
Performance. Each Party acknowledges that, in view of the uniqueness of the securities referenced herein and the transactions
contemplated by this Agreement, the other Party would not have an adequate remedy at law for money damages in the event that this
Agreement has not been performed in accordance with its terms, and therefore agrees that the other Party shall be entitled to specific
performance and injunctive or other equitable relief, without the necessity of proving the inadequacy of monetary damages as a
remedy.


10.18      Waiver
of Consequential Damages. Notwithstanding any provision in this Agreement to the contrary, in no event shall any Party or its
Affiliates, or their respective managers, members, shareholders or representatives, be liable hereunder at any time for punitive,
incidental, consequential special or indirect damages, including loss of future profits, revenue or income, or loss of business
reputation of any other Party or any of its Affiliates, whether in contract, tort (including negligence), strict liability or otherwise,
and each Party hereby expressly releases each other Party, its Affiliates, and their respective managers, members, shareholders,
partners, consultants, representatives, successors and assigns therefrom.

10.19   Rules
of Construction. The Parties and their respective legal counsel participated in the preparation of this Agreement, and therefore,
this Agreement shall be construed neither against nor in favor of any of the Parties, but rather in accordance with the fair meaning
thereof. All definitions set forth in this Agreement are deemed applicable whether the words defined are used in this Agreement
in the singular or in the plural, and correlative forms of defined terms have corresponding meanings. The term “including”
is not limiting and means “including without limitation.” The term “or” has, except where otherwise indicated,
the inclusive meaning represented by the phrase “and/or.” The words “hereof,” “herein,” “hereby,”
“hereunder” and similar terms in this Agreement refer to this Agreement as a whole and not to any particular provision
of this Agreement. Section, subsection, clause, schedule, annex and exhibit references are to this Agreement unless otherwise specified.
Any reference to this Agreement shall include all alterations, amendments, changes, extensions, modifications, renewals, replacements,
substitutions, and supplements thereto and thereof, as applicable. Whenever the context may require, any pronoun includes the corresponding
masculine, feminine and neuter forms.
