NOW, THEREFORE,
in consideration of the promises and the mutual covenants contained herein and other good and valuable consideration, the receipt

d.       “Registration
Statement” means a registration statement of the Company covering only the sale of the Registrable Securities.


 


2.            REGISTRATION.


 


a.       Mandatory
Registration. The Company shall within Ten (10) Business Days from the date hereof file with the SEC the Registration Statement.
The Registration Statement shall register only the Registrable Securities and no other securities of the Company. Except as provided
herein, the Buyer and its counsel shall have a reasonable opportunity to review and comment upon such Registration Statement or
any amendment to such Registration Statement and any related prospectus prior to its filing with the SEC. The Buyer shall furnish
all information reasonably requested by the Company for inclusion therein. The Company shall use its reasonable best efforts to
have the Registration Statement or any amendment declared effective by the SEC as soon as reasonably practicable. Subject to Permitted
Delays (as defined below) and Section 3(e), the Company shall use reasonable best efforts to keep the Registration Statement effective
pursuant to Rule 415 promulgated under the 1933 Act and available for sales of all of the Registrable Securities at all times until
the earlier of (i) the date as of which the Buyer may sell all of the Registrable Securities without restriction pursuant to Rule
144 promulgated under the 1933 Act (or successor thereto) or (ii) the date on which the Buyer shall have sold all the Registrable
Securities and no Available Amount remains under the Purchase Agreement (the “Registration Period”). Except
as contemplated in Section 3(e), and except with respect to the information furnished in writing to the Company by the Buyer expressly
for use in connection with the preparation of the Registration Statement and any amendments or supplements thereto or prospectus
contained therein (as to which the Company makes no representation or warranty), the Registration Statement (including any amendments
or supplements thereto and prospectuses 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
under which they were made, not misleading.


 


b.       Rule
424 Prospectus. The Company shall, to the extent required by applicable securities regulations, from time to time file with
the SEC, pursuant to Rule 424 promulgated under the 1933 Act, a prospectus and prospectus supplements, if any, to be used in connection
with sales of the Registrable Securities under the Registration Statement. The Buyer and its counsel shall have two (2) Business
Days to review and comment upon such prospectus prior to its filing with the SEC. The Buyer shall use its reasonable best efforts
to comment upon such prospectus within two (2) Business Days from the date the Buyer receives the final version of such prospectus.


 


c.       Sufficient
Number of Securities Registered. In the event the number of securities available under the Registration Statement is insufficient
to cover the Registrable Securities, the Company shall, to the extent necessary and permissible, amend the Registration Statement
or file a new registration statement (a “New Registration Statement”), so as to cover all such Registrable Securities
as soon as reasonably practicable, but in any event not later than ten (10) Business Days after the necessity therefor arises.
The Company shall use its reasonable best efforts to have such amendment and/or New Registration Statement become effective as
soon as reasonably practicable following the filing thereof.


 






    	 	2	 



     


    

 


3.            RELATED
OBLIGATIONS.


 


With respect to the
Registration Statement and whenever any Registrable Securities are to be registered pursuant to Sections 2(a) and (c), including
on any New Registration Statement, the Company shall use its reasonable best efforts to effect the registration of the Registrable
Securities in accordance with the intended method of disposition thereof and, pursuant thereto, the Company shall have the following
obligations:


 


a.       The
Company shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to any Registration
Statement and the prospectus used in connection with such Registration Statement, as may be necessary to keep the Registration
Statement or any New Registration Statement effective at all times during the Registration Period, subject to Permitted Delays
and Section 3(e) hereof and, during such period, comply with the provisions of the 1933 Act with respect to the disposition of
all Registrable Securities of the Company covered by the Registration Statement or any New Registration Statement until such time
as all of such Registrable Securities shall have been disposed of in accordance with the intended methods of disposition by the
seller or sellers thereof as set forth in such Registration Statement. Should the Company file a post-effective amendment to the
Registration Statement or a New Registration Statement, the Company will use its reasonable best efforts to have such filing declared
effective by the SEC within thirty (30) consecutive Business Days following the date of filing, 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. If
(i) there is material non-public information regarding the Company which the Company’s Board of Directors reasonably determines
not to be in the Company’s best interest to disclose and which the Company is not otherwise required to disclose or (ii)
there is a significant business opportunity (including, but not limited to, the acquisition or disposition of assets (other than
in the ordinary course of business) or any merger, consolidation, tender offer or other similar transaction) available to the
Company which the Company’s Board of Directors reasonably determines not to be in the Company’s best interest to disclose
and which the Company would be required to disclose under a Registration Statement or a New Registration Statement, then the Company
may postpone or suspend filing or effectiveness of such Registration Statement or New Registration Statement or use of the prospectus
under the Registration Statement or New Registration Statement for a period not to exceed thirty (30) consecutive days, provided
that the Company may not postpone or suspend its obligation under this Section 3(a) for more than sixty (60) days in the aggregate
during any twelve (12) month period (each, a “Permitted Delay”).


 


b.       The
Company shall submit to the Buyer for review and comment any disclosure in the Registration Statement, any New Registration Statement
and all amendments and supplements thereto (other than prospectus supplements that consist only of a copy of a filed Form 20-F
or a Report on Form 6-K or any amendment as a result of the Company’s filing of a document that is incorporated by reference
into the Registration Statement or New Registration Statement) containing information provided by the Buyer for inclusion in such
document and any descriptions or disclosure regarding the Buyer, the Purchase Agreement, including the transaction contemplated
thereby, or this Agreement at least two (2) Business Days prior to their filing with the SEC, and not file any document in a form
to which Buyer reasonably and timely objects. Upon request of the Buyer, the Company shall provide to the Buyer all disclosure
in the Registration Statement or any New Registration Statement and all amendments and supplements thereto (other than prospectus
supplements that consist only of a copy of a filed Form 20-F or Report on Form 6-K or any amendment as a result of the Company’s
filing of a document that is incorporated by reference into the Registration Statement or New Registration Statement) at least
two (2) Business Days prior to their filing with the SEC, and not file any document in a form to which Buyer reasonably and timely
objects. The Buyer shall use its reasonable best efforts to comment upon the Registration Statement or any New Registration Statement
and any amendments or supplements thereto within two (2) Business Days from the date the Buyer receives the final version thereof.
The Company shall furnish to the Buyer, without charge, any correspondence from the SEC or the staff of the SEC to the Company
or its representatives relating to the Registration Statement or any New Registration Statement.


 






    	 	3	 



     


    

 


c.       Upon
request of the Buyer, the Company shall furnish to the Buyer, (i) promptly after the same is prepared and filed with the SEC, at
least one copy of the Registration Statement and any amendment(s) thereto, including all financial statements and schedules, all
documents incorporated therein by reference and all exhibits, (ii) upon the effectiveness of a Registration Statement, a copy of
the prospectus included in such Registration Statement and all amendments and supplements thereto (or such other number of copies
as the Buyer may reasonably request) and (iii) such other documents, including copies of any preliminary or final prospectus, as
the Buyer may reasonably request from time to time in order to facilitate the disposition of the Registrable Securities owned by
the Buyer.


 


d.       The
Company shall use reasonable best efforts to (i) register and qualify, unless an exemption from registration and qualification
is available, the Registrable Securities covered by a Registration Statement under such other securities or “blue sky”
laws of such jurisdictions in the United States as the Buyer reasonably requests, (ii) subject to Permitted Delays, prepare and
file in those jurisdictions, such amendments (including post-effective amendments) and supplements to such registrations and qualifications
as may be necessary to maintain the effectiveness thereof during the Registration Period, (iii) take such other actions as may
be necessary to maintain such registrations and qualifications in effect at all times during the Registration Period, and (iv)
take all other actions reasonably necessary or advisable to qualify the Registrable Securities for sale in such jurisdictions;
provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (x) qualify to do
business in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(d), (y) subject itself
to general taxation in any such jurisdiction, or (z) file a general consent to service of process in any such jurisdiction. The
Company shall promptly notify the Buyer who holds Registrable Securities of the receipt by the Company of any notification with
respect to the suspension of the registration or qualification of any of the Registrable Securities for sale under the securities
or “blue sky” laws of any jurisdiction in the United States or its receipt of actual notice of the initiation or threat
of any proceeding for such purpose.


 


e.       Subject
to Permitted Delays, as promptly as reasonably practicable after becoming aware of such event or facts, the Company shall notify
the Buyer in writing if the Company has determined that the prospectus included in any Registration Statement, as then in effect,
includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were made, not misleading, and as promptly as reasonably
practical (taking into account the Company’s good faith assessment of any adverse consequences to the Company and its stockholders
of premature disclosure of such event or facts) prepare a prospectus supplement or amendment to such Registration Statement to
correct such untrue statement or omission, and, upon the Buyer’s request, deliver a copy of such prospectus supplement or
amendment to the Buyer. In providing this notice to the Buyer, the Company shall not include any other information about the facts
underlying the Company’s determination and shall not in any way communicate any material nonpublic information about the
Company or the Securities to the Buyer. The Company shall also promptly notify the Buyer in writing (i) when a prospectus or any
prospectus supplement or post-effective amendment has been filed, and when a Registration Statement or any post-effective amendment
has become effective (notification of such effectiveness shall be delivered to the Buyer by facsimile or e-mail on the same day
of such effectiveness), (ii) of any request by the SEC for amendments or supplements to any Registration Statement or related prospectus
or related information, and (iii) of the Company’s reasonable determination that a post-effective amendment to a Registration
Statement would be appropriate. In no event shall the delivery of a notice under this Section 3(e), or the resulting unavailability
of a Registration Statement, without regard to its duration, for disposition of securities by Buyer be considered a breach by the
Company of its obligations under this Agreement. The preceding sentence in this Section 3(e) does not limit whether an event of
default has occurred as set forth in Section 9(a) of the Purchase Agreement.


 






    	 	4	 



     


    

 


f.       The
Company shall use its reasonable best efforts to prevent the issuance of any stop order or other suspension of effectiveness of
any Registration Statement, or the suspension of the qualification of any Registrable Securities for sale in any jurisdiction and,
if such an order or suspension is issued, to obtain the withdrawal of such order or suspension at the earliest practical time and
to notify the Buyer of the issuance of such order and the resolution thereof or its receipt of actual notice of the initiation
or threat of any proceeding for such purpose.


 


g.       The
Company shall (i) cause all the Registrable Securities to be listed on each securities exchange on which securities of the same
class or series issued by the Company are then listed, if any, if the listing of such Registrable Securities is then permitted
under the rules of such exchange, or (ii) secure designation and quotation of all the Registrable Securities if the Principal Market
(as such term is defined in the Purchase Agreement) is an automated quotation system. The Company shall pay all fees and expenses
in connection with satisfying its obligation under this Section.


 


h.       The
Company shall cooperate with the Buyer to facilitate the timely preparation and delivery of certificates (not bearing any restrictive
legend) representing the Registrable Securities to be offered pursuant to any Registration Statement and enable such certificates
to be in such denominations or amounts as the Buyer may reasonably request and registered in such names as the Buyer may request.


 


i.       The
Company shall at all times provide a transfer agent and registrar with respect to its Securities.


 


j.       If
reasonably requested by the Buyer, the Company shall (i) promptly incorporate in a prospectus supplement or post-effective amendment
to the Registration Statement such information as the Buyer believes should be included therein relating to the sale and distribution
of Registrable Securities, including, without limitation, information with respect to the number of Registrable Securities being
sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities; (ii) make all required
filings of such prospectus supplement or post-effective amendment as promptly as practicable once notified of the matters to be
incorporated in such prospectus supplement or post-effective amendment; and (iii) supplement or make amendments to any Registration
Statement (including by means of any document incorporated therein by reference).


 


k.       The
Company shall use its reasonable best efforts to cause the Registrable Securities covered by any Registration Statement to be registered
with or approved by such other governmental agencies or authorities in the United States as may be necessary to consummate the
disposition of such Registrable Securities.





 






    	 	5	 



     


    

 


l.       Within
two (2) Business Days after any Registration Statement is ordered effective by the SEC, the Company shall deliver to the Transfer
Agent for such Registrable Securities (with copies to the Buyer) confirmation that such Registration Statement has been declared
effective by the SEC in the form attached hereto as Exhibit A. Thereafter, if reasonably requested by the Buyer at any
time, the Company shall deliver to the Buyer a written confirmation of whether or not the effectiveness of such Registration Statement
has lapsed at any time for any reason (including, without limitation, the issuance of a stop order) and whether or not the Registration
Statement is currently effective and available to the Buyer for sale of all of the Registrable Securities.


 


m.       The
Company agrees to take all other reasonable actions as necessary and reasonably requested by the Buyer to expedite and facilitate
disposition by the Buyer of Registrable Securities pursuant to any Registration Statement.


 


4.            OBLIGATIONS
OF THE BUYER.


 


a.       The
Buyer has furnished to the Company in Exhibit B hereto such information regarding itself, the Registrable Securities held
by it and the intended method of disposition of the Registrable Securities held by it as required to effect the registration of
such Registrable Securities and shall execute such documents in connection with such registration as the Company may reasonably
request. The Company shall notify the Buyer in writing of any other information the Company reasonably requires from the Buyer
in connection with any Registration Statement hereunder. The Buyer will as promptly as practicable notify the Company of any material
change in the information set forth in Exhibit B, other than changes in its ownership of the Registrable Securities.


 


b.       The
Buyer agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing
of any amendments and supplements to any Registration Statement hereunder.


 


c.       The
Buyer agrees that, upon receipt of any notice from the Company of the happening of any event or existence of facts of the kind
described in Section 3(f) or any notice of the kind described in the first sentence of Section 3(e), the Buyer will immediately
discontinue disposition of Registrable Securities pursuant to any registration statement(s) covering such Registrable Securities
until the Buyer’s receipt (which may be accomplished through electronic delivery) of the copies of the filed supplemented
or amended registration statement and/or prospectus contemplated by Section 3(f) or the first sentence of Section 3(e). In addition,
upon receipt of any notice from the Company of the kind described in the first sentence of Section 3(e), the Buyer will immediately
discontinue purchases or sales of any securities of the Company unless such purchases or sales are in compliance with applicable
U.S. securities laws. Notwithstanding anything to the contrary, the Company shall cause its Transfer Agent to deliver as promptly
as practicable Securities without any restrictive legend in accordance with the terms of the Purchase Agreement in connection with
any sale of Registrable Securities with respect to which the Buyer has received a Purchase Notice or VWAP Purchase Notice (both
as defined in the Purchase Agreement) prior to the Buyer’s receipt of a notice from the Company of the happening of any event
of the kind described in Section 3(f) or the first sentence of Section 3(e) and for which the Buyer has not yet settled.


 






    	 	6	 



     


    

 


5.            EXPENSES
OF REGISTRATION.


 


All reasonable expenses
of the Company, other than sales or brokerage commissions and fees and disbursements of counsel for the Buyer, incurred in connection
with registrations, filings or qualifications pursuant to Sections 2 and 3, including, without limitation, all registration, listing
and qualifications fees, printers and accounting fees, and fees and disbursements of counsel for the Company, shall be paid by
the Company.


 


6.            INDEMNIFICATION.


 


a.       To
the fullest extent permitted by law, the Company will, and hereby does, indemnify, hold harmless and defend the Buyer, each Person,
if any, who controls the Buyer, the members, the directors, officers, partners, employees, agents, representatives of the Buyer
and each Person, if any, who controls the Buyer within the meaning of the 1933 Act or the Securities Exchange Act of 1934, as amended
(the “1934 Act”) (each, an “Indemnified Person”), against any third party losses, claims,
damages, liabilities, judgments, fines, penalties, charges, costs, reasonable attorneys’ fees, amounts paid in settlement
(with the prior consent of the Company, such consent not to be unreasonably withheld) or reasonable expenses, (collectively, “Claims”)
reasonably incurred in investigating, preparing or defending any action, claim, suit, inquiry, proceeding, investigation or appeal
taken from the foregoing by or before any court or governmental, administrative or other regulatory agency or body or the SEC,
whether pending or threatened, whether or not an indemnified party is or may be a party thereto (“Indemnified Damages”),
to which any of them may become subject insofar as such Claims (or actions or proceedings, whether commenced or threatened, in
respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of a material fact in the
Registration Statement, any New Registration Statement or any post-effective amendment thereto or in any filing made in connection
with the qualification of the offering under the securities or other “blue sky” laws of any jurisdiction in which Registrable
Securities are offered (“Blue Sky Filing”), or the omission or alleged omission to state a material fact required
to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement
of a material fact contained in the final prospectus (as amended or supplemented, if the Company files any amendment thereof or
supplement thereto with the SEC) or the omission or alleged omission to state therein any material fact necessary to make the statements
made therein, in light of the circumstances under which the statements therein were made, not misleading, or (iii) any violation
or alleged violation by the Company of the 1933 Act, the 1934 Act, any other law, including, without limitation, any state securities
law, or any rule or regulation thereunder relating to the offer or sale of the Registrable Securities pursuant to the Registration
Statement or any New Registration Statement (the matters in the foregoing clauses (i) through (iii) being, collectively, “Violations”).
The Company shall reimburse each Indemnified Person promptly as such expenses are incurred and are due and payable, for any reasonable
legal fees or other reasonable expenses incurred by them in connection with investigating or defending any such Claim. Notwithstanding
anything to the contrary contained herein, the indemnification agreement contained in this Section 6(a): (A) shall not apply to
a Claim by an Indemnified Person arising out of or based upon a Violation which occurs in reliance upon and in conformity with
information furnished in writing to the Company by the Buyer or such Indemnified Person expressly for use in connection with the
preparation of the Registration Statement, any New Registration Statement or any such amendment thereof or supplement thereto,
if such prospectus was timely made available by the Company; (B) with respect to any superseded prospectus, shall not inure to
the benefit of any such person from whom the person asserting any such Claim purchased the Registrable Securities that are the
subject thereof (or to the benefit of any other Indemnified Person) if the untrue statement or omission of material fact contained
in the superseded prospectus was corrected in the revised prospectus, as then amended or supplemented, if such revised prospectus
was timely made available by the Company pursuant to Section 3(c) or Section 3(e), and the Indemnified Person was promptly advised
in writing not to use the incorrect prospectus prior to the use giving rise to a violation; (C) shall not be available to the extent
such Claim is based on a failure of the Buyer to deliver, or to cause to be delivered, the prospectus made available by the Company,
if such prospectus was theretofore made available by the Company pursuant to Section 3(c) or Section 3(e); and (D) 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. Such indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable Securities by the Buyer pursuant
to Section 9.


 






    	 	7	 



     


    

 


b.       In
connection with the Registration Statement or any New Registration Statement or prospectus, the Buyer agrees to indemnify, hold
harmless and defend, to the same extent and in the same manner as is set forth in Section 6(a), the Company, each of its directors,
each of its officers who signs the Registration Statement or any New Registration Statement, each Person, if any, who controls
the Company within the meaning of the 1933 Act or the 1934 Act (collectively and together with an Indemnified Person, an “Indemnified
Party”), against any Claim or Indemnified Damages to which any of them may become subject, under the 1933 Act, the 1934
Act or otherwise, insofar as such Claim or Indemnified Damages arise out of or are based upon any Violation, in each case to the
extent, and only to the extent, that such Violation occurs in reliance upon and in conformity with written information about the
Buyer set forth on Exhibit B attached hereto or updated from time to time in writing by the Buyer and furnished to the Company
by the Buyer expressly for use in the Registration Statement or any New Registration Statement or from the failure of the Buyer
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 3(c) or Section 3(e); and, subject to Section 6(d), the Buyer will reimburse any legal or other
expenses reasonably incurred by them in connection with investigating or defending any such Claim; provided, however, that the
indemnity agreement contained in this Section 6(b) and the agreement with respect to contribution contained in Section 7 shall
not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Buyer,
which consent shall not be unreasonably withheld; provided, further, however, that the Buyer shall be liable under this Section
6(b) for only that amount of a Claim or Indemnified Damages as does not exceed the net proceeds to the Buyer as a result of the
sale of Registrable Securities pursuant to such registration statement. Such indemnity shall remain in full force and effect regardless
of any investigation made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities
by the Buyer pursuant to Section 9.


 






    	 	8	 



     


    

 


c.       Promptly
after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any action or
proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified Party shall,
if a Claim in respect thereof is to be made against any indemnifying party under this Section 6, deliver to the indemnifying party
a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense
thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the
case may be, and upon such notice, the indemnifying party shall not be liable to the Indemnified Person or Indemnified Party for
any legal or other expenses subsequently incurred by the Indemnified Person or Indemnified Party in connection with the defense
thereof; provided, however, that an Indemnified Person or Indemnified Party (together with all other Indemnified Persons and Indemnified
Parties that may be represented without conflict by one counsel) shall have the right to retain its own counsel with the fees and
expenses to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the
representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate
due to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other party represented
by such counsel in such proceeding. The Indemnified Party or Indemnified Person shall cooperate with the indemnifying party in
connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying
party all information reasonably available to the Indemnified Party or Indemnified Person which relates to such action or claim.
The indemnifying party shall keep the Indemnified Party or Indemnified Person fully apprised as to the status of the defense or
any settlement negotiations with respect thereto. No indemnifying party shall be liable for any settlement of any action, claim
or proceeding effected without its written consent, provided, however, that the indemnifying party shall not unreasonably withhold,
delay or condition its consent. No indemnifying party shall, without the consent of the Indemnified Party or Indemnified Person,
consent to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional term
thereof the giving by the claimant or plaintiff to such Indemnified Party or Indemnified Person of a release from all liability
in respect to such claim or litigation. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated
to all rights of the Indemnified Party or Indemnified Person with respect to all third parties, firms or corporations relating
to the matter for which indemnification has been made. The failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified
Person or Indemnified Party under this Section 6, except to the extent that the indemnifying party is prejudiced in its ability
to defend such action.


 


d.       The
indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the investigation
or defense, as and when bills are received or Indemnified Damages are incurred. Any person receiving a payment pursuant to this
Section 6 which person is later determined to not be entitled to such payment shall return such payment (including reimbursement
of expenses) to the person making it.


 


e.       The
indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified Party
or Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject
to pursuant to the law.


 


7.            CONTRIBUTION.


 


To the extent any indemnification
by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect
to any amounts for which it would otherwise be liable under Section 6 to the fullest extent permitted by law; provided, however,
that: (i) no seller of Registrable Securities guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the
1933 Act) shall be entitled to contribution from any party who was not guilty of fraudulent misrepresentation; and (ii) contribution
by any seller of Registrable Securities shall be limited in amount to the net amount of proceeds received by such seller from the
sale of such Registrable Securities.

8.            REPORTS
AND DISCLOSURE UNDER THE SECURITIES ACTS.


 


With a view to making
available to the Buyer the benefits of Rule 144 promulgated under the 1933 Act or any other similar rule or regulation of the SEC

RE: AKARI THERAPEUTICS, PLC


 


Ladies and Gentlemen:


 


We refer to that certain
Securities Purchase Agreement, dated as of June 30, 2020 (the “Purchase Agreement”), entered into by and between
AKARI THERAPEUTICS, PLC, a public limited company incorporated under the laws of England and Wales (the “Company”)
and ASPIRE CAPITAL FUND, LLC (the “Buyer”) pursuant to which the Company has agreed to issue to the Buyer
American Depositary Shares (“ADSs”) representing interests in ordinary shares of the Company (“Ordinary
Shares” and together with the ADSs, the “Securities”) , in an amount up to Thirty Million Dollars
($30,000,000), in accordance with the terms of the Purchase Agreement. In connection with the transactions contemplated by the
Purchase Agreement, the Company has registered with the U.S. Securities and Exchange Commission (the “SEC”)
the sale by the Buyer of the following Securities:


 


		(1)	up to __________________________ ADSs representing interests in Ordinary Shares to be issued upon
purchase from the Company by the Buyer from time to time (the “Purchase Securities”); and



 


(2) 407,609
ADSs representing interests in Ordinary Shares which have been previously issued to the Buyer under the Securities Purchase Agreement
(the “Issued Securities”).


 


In connection with the transactions contemplated
by the Purchase Agreement, the Company has filed a registration statement on Form F-1 (File No. 333_________) (the “Registration
Statement”) with the SEC relating to the sale by the Buyer of the Purchase Securities and the Issued Securities. Accordingly,
we advise you that (i) the SEC has entered an order declaring the Registration Statement effective under the Securities Act of
1933 Act (the “1933 Act”) at ___ [A./P.]M. on __________, 202_, (ii) we have no knowledge, after review of the
stop order notification website maintained by the SEC, that any stop order suspending its effectiveness has been issued or that
any proceedings for that purpose are pending before, or threatened by, the SEC and (iii) the Purchase Securities and the Issued
Securities are available for sale under the 1933 Act pursuant to the Registration Statement. Accordingly, and in reliance on certain
covenants made by the Buyer regarding the manner of sale of the Securities, (1) the restrictive legend on the certificates representing
the Issued Securities may be removed and (2) certificates representing Purchase Securities to be issued may be issued without any
restrictive legend.


 



     

     


    




 





	 	Very truly yours,
	 	 	 
	 	 	 
	 	By:	____________________

Plan of Distribution


 


The Securities may be sold or distributed from time to time
by the selling security holder directly to one or more purchasers or through brokers, dealers, or underwriters who may act solely
as agents at market prices prevailing at the time of sale, at prices related to the prevailing market prices, at negotiated prices,
or at fixed prices, which may be changed. The sale of the Securities offered by this prospectus may be effected in one or more
of the following methods:


 


		·	ordinary brokers’ transactions;


 

		·	transactions involving cross or block trades;


 

		·	through brokers, dealers, or underwriters who may act solely as agents;


 

		·	“at the market” into an existing market for the Securities;


 

		·	in other ways not involving market makers or established business
markets, including direct sales to purchasers or sales effected through agents;


 

		·	in privately negotiated transactions; or


 

		·	any combination of the foregoing.



 


In order to comply with the securities
laws of certain states, if applicable, the securities may be sold only through registered or licensed brokers or dealers. In addition,
in certain states, the securities may not be sold unless they have been registered or qualified for sale in the state or an exemption
from the registration or qualification requirement is available and complied with.


 


The selling security holder may transfer
the Securities by other means not described in this prospectus.


 


Brokers, dealers, underwriters, or agents
participating in the distribution of the securities as agents may receive compensation in the form of commissions, discounts, or
concessions from the selling security holder and/or purchasers of the Securities for whom the broker-dealers may act as agent.
Aspire Capital has informed us that each such broker-dealer will receive commissions from Aspire Capital which will not exceed
customary brokerage commissions.


 






     

     


    

 


The selling security holder and its affiliates
have agreed not to engage in any direct or indirect short selling or hedging of our Securities during the term of the Purchase
Agreement.


 


The selling security holder is an “underwriter”
within the meaning of the Securities Act. We have agreed to provide indemnification and contribution to the selling security holder
against certain civil liabilities, including liabilities under the Securities Act.


 


We have advised the selling security holder
that while it is engaged in a distribution of the securities included in this prospectus, it is required to comply with Regulation
M promulgated under the Securities Exchange Act of 1934, as amended. With certain exceptions, Regulation M precludes the selling
security holder, any affiliated purchasers, and any broker-dealer or other person who participates in the distribution from bidding
for or purchasing, or attempting to induce any person to bid for or purchase any security which is the subject of the distribution
until the entire distribution is complete. Regulation M also prohibits any bids or purchases made in order to stabilize the price
of a security in connection with the distribution of that security. All of the foregoing may affect the marketability of the securities
offered hereby this prospectus.


 


We may suspend the sale of securities by
the selling security holder pursuant to this prospectus for certain periods of time for certain reasons, including if the prospectus
is required to be supplemented or amended to include additional material information.


 


This offering as it relates to Aspire Capital
will terminate on the date that all Securities offered by this prospectus have been sold by Aspire Capital.
