2.        Shelf
Registration.


 


(a)              
On or prior to each Filing Date, the Company shall prepare and file with the Commission a Registration Statement covering
the resale of all of the Registrable Securities that are not then registered on an effective Registration Statement for an offering
to be made on a continuous basis pursuant to Rule 415. Each Registration Statement filed hereunder shall be on Form F-3 (except
if the Company is not then eligible to register for resale the Registrable Securities on Form F-3, in which case such registration
shall be on another appropriate form in accordance herewith, subject to the provisions of Section 2(e)) and shall contain (unless
otherwise directed by at least 85% in interest of the Holders) substantially the “Plan of Distribution” attached
hereto as Annex A and substantially the “Selling Stockholder” section attached hereto as Annex B;
provided, however, that no Holder shall be required to be named as an “underwriter” without such Holder’s
express prior written consent. Subject to the terms of this Agreement, the Company shall use its best efforts to cause a Registration
Statement filed under this Agreement (including, without limitation, under Section 3(c)) to be declared effective under the Securities
Act as promptly as possible after the filing thereof, but in any event no later than the applicable Effectiveness Date, and shall
use its best efforts to keep such Registration Statement continuously effective under the Securities Act until the date that all
Registrable Securities covered by such Registration Statement (i) have been sold, thereunder or pursuant to Rule 144, or (ii)
may be sold without volume or manner-of-sale restrictions pursuant to Rule 144 and without the requirement for the Company to
be in compliance with the current public information requirement under Rule 144, as determined by the counsel to the Company pursuant
to a written opinion letter to such effect, addressed and acceptable to the Transfer Agent and the affected Holders (the “Effectiveness
Period”). The Company shall telephonically request effectiveness of a Registration Statement as of 5:00 p.m. (New York
City time) on a Trading Day. The Company shall immediately notify the Holders via facsimile or by e-mail of the effectiveness
of a Registration Statement on the same Trading Day that the Company telephonically confirms effectiveness with the Commission,
which shall be the date requested for effectiveness of such Registration Statement. The Company shall, by 9:30 a.m. (New York
City time) on the Trading Day after the effective date of such Registration Statement, file a final Prospectus with the Commission
as required by Rule 424. Failure to so notify the Holder within one (1) Trading Day of such notification of effectiveness or failure
to file a final Prospectus as foresaid shall be deemed an Event under Section 2(d).


 


(b)              
 Notwithstanding the registration obligations set forth in Section 2(a), if the Commission informs the Company that all
of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering
on a single registration statement, the Company agrees to promptly inform each of the Holders thereof and use its commercially
reasonable efforts to file amendments to the Initial Registration Statement as required by the Commission, covering the maximum
number of Registrable Securities permitted to be registered by the Commission, on Form F-3 or such other form available to register
for resale the Registrable Securities as a secondary offering, subject to the provisions of Section 2(e); with respect to filing
on Form F-3 or other appropriate form, and subject to the provisions of Section 2(d) with respect to the payment of liquidated
damages; provided, however, that prior to filing such amendment, the Company shall be obligated to use diligent
efforts to advocate with the Commission for the registration of all of the Registrable Securities in accordance with the SEC Guidance,
including without limitation, Compliance and Disclosure Interpretation 612.09.


 






    4


     


    

 


(c)              
Notwithstanding any other provision of this Agreement and subject to the payment of liquidated damages pursuant to Section
2(d), if the Commission or any SEC Guidance sets forth a limitation on the number of Registrable Securities permitted to be registered
on a particular Registration Statement as a secondary offering (and notwithstanding that the Company used diligent efforts to
advocate with the Commission for the registration of all or a greater portion of Registrable Securities), unless otherwise directed
in writing by a Holder as to its Registrable Securities, the number of Registrable Securities to be registered on such Registration
Statement will be reduced as follows: 


 


		a.	First, the Company shall
                                         reduce or eliminate any securities to be included other than Registrable Securities;
                                         and



 


		b.	Second, the Company shall
                                         reduce Registrable Securities represented by Warrant Shares (applied, in the case that
                                         some Warrant Shares may be registered, to the Holders on a pro rata basis based on the
                                         total number of unregistered Warrant Shares held by such Holders). 



 


In the event of a cutback hereunder,
the Company shall give the Holder at least five (5) Trading Days prior written notice along with the calculations as to such Holder’s
allotment. In the event the Company amends the Initial Registration Statement in accordance with the foregoing, the Company will
use its best efforts to file with the Commission, as promptly as allowed by Commission or SEC Guidance provided to the Company
or to registrants of securities in general, one or more registration statements on Form F-3 or such other form available to register
for resale those Registrable Securities that were not registered for resale on the Initial Registration Statement, as amended.


 






    5


     


    

 


(d)              
If: (i) the Initial Registration Statement is not filed on or prior to its Filing Date (if the Company files the Initial
Registration Statement without affording the Holders the opportunity to review and comment on the same as required by Section
3(a) herein, the Company shall be deemed to have not satisfied this clause (i)), or (ii) the Company fails to file with the Commission
a request for acceleration of a Registration Statement in accordance with Rule 461 promulgated by the Commission pursuant to the
Securities Act, within five Trading Days of the date that the Company is notified (orally or in writing, whichever is earlier)
by the Commission that such Registration Statement will not be “reviewed” or will not be subject to further review,
or (iii) prior to the effective date of a Registration Statement, the Company fails to file a pre-effective amendment and otherwise
respond in writing to comments made by the Commission in respect of such Registration Statement within ten (10) calendar days
after the receipt of comments by or notice from the Commission that such amendment is required in order for such Registration
Statement to be declared effective, or (iv) a Registration Statement registering for resale all of the Registrable Securities
is not declared effective by the Commission by the Effectiveness Date of the Initial Registration Statement, or (v) after the
effective date of a Registration Statement, such Registration Statement ceases for any reason to remain continuously effective
as to all Registrable Securities included in such Registration Statement, or the Holders are otherwise not permitted to utilize
the Prospectus therein to resell such Registrable Securities, for more than ten (10) consecutive calendar days or more than an
aggregate of fifteen (15) calendar days (which need not be consecutive calendar days) during any 12-month period (any such failure
or breach being referred to as an “Event”, and for purposes of clauses (i) and (iv), the date on which such
Event occurs, and for purpose of clause (ii) the date on which such five (5) Trading Day period is exceeded, and for purpose of
clause (iii) the date which such ten (10) calendar day period is exceeded, and for purpose of clause (v) the date on which such
ten (10) or fifteen (15) calendar day period, as applicable, is exceeded being referred to as “Event Date”),
then, in addition to any other rights the Holders may have hereunder or under applicable law, on each such Event Date and on each
monthly anniversary of each such Event Date (if the applicable Event shall not have been cured by such date) until the applicable
Event is cured, the Company shall pay to each Holder an amount in cash, as partial liquidated damages and not as a penalty, equal
to the product of 2.0% multiplied by the aggregate Subscription Amount paid by such Holder pursuant to the Purchase Agreement.
If the Company fails to pay any partial liquidated damages pursuant to this Section in full within seven days after the date payable,
the Company will pay interest thereon at a rate of 18% per annum (or such lesser maximum amount that is permitted to be paid by
applicable law) to the Holder, accruing daily from the date such partial liquidated damages are due until such amounts, plus all
such interest thereon, are paid in full. The partial liquidated damages pursuant to the terms hereof shall apply on a daily pro
rata basis for any portion of a month prior to the cure of an Event.


 


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


 


(f)               
Notwithstanding anything to the contrary contained herein, in no event shall the Company be permitted to name any Holder
or affiliate of a Holder as any Underwriter without the prior written consent of such Holder.

3.        Registration
Procedures.


 


In connection with
the Company’s registration obligations hereunder, the Company shall:


 


(a)              
Not less than five (5) Trading Days prior to the filing of each Registration Statement and not less than one (1) Trading
Day prior to the filing of any related Prospectus or any amendment or supplement thereto (including any document that would be
incorporated or deemed to be incorporated therein by reference), the Company shall (i) furnish to each Holder copies of all such
documents proposed to be filed, which documents (other than those incorporated or deemed to be incorporated by reference) will
be subject to the review of such Holders, and (ii) cause its officers and directors, counsel and independent registered public
accountants to respond to such inquiries as shall be necessary, in the reasonable opinion of respective counsel to each Holder,
to conduct a reasonable investigation within the meaning of the Securities Act. The Company shall not file a Registration Statement
or any such Prospectus or any amendments or supplements thereto to which the Holders of a majority of the Registrable Securities
shall reasonably object in good faith, provided that, the Company is notified of such objection in writing no later than five
(5) Trading Days after the Holders have been so furnished copies of a Registration Statement or one (1) Trading Day after the
Holders have been so furnished copies of any related Prospectus or amendments or supplements thereto. Each Holder agrees to furnish
to the Company a completed questionnaire in the form attached to this Agreement as Annex B (a “Selling Stockholder
Questionnaire”) on a date that is not less than two (2) Trading Days prior to the Filing Date or by the end of the fourth
(4th) Trading Day following the date on which such Holder receives draft materials in accordance with this Section.


 


(b)              
(i) Prepare and file with the Commission such amendments, including post-effective amendments, to a Registration Statement
and the Prospectus used in connection therewith as may be necessary to keep a Registration Statement continuously effective as
to the applicable Registrable Securities for the Effectiveness Period and prepare and file with the Commission such additional
Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities, (ii) cause
the related Prospectus to be amended or supplemented by any required Prospectus supplement (subject to the terms of this Agreement),
and, as so supplemented or amended, to be filed pursuant to Rule 424, (iii) respond as promptly as reasonably possible to any
comments received from the Commission with respect to a Registration Statement or any amendment thereto and provide as promptly
as reasonably possible to the Holders true and complete copies of all correspondence from and to the Commission relating to a
Registration Statement (provided that, the Company shall excise any information contained therein which would constitute material
non-public information regarding the Company or any of its Subsidiaries), and (iv) comply in all material respects with the applicable
provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by
a Registration Statement during the applicable period in accordance (subject to the terms of this Agreement) with the intended
methods of disposition by the Holders thereof set forth in such Registration Statement as so amended or in such Prospectus as
so supplemented.


 






    7


     


    

 


(c)              
If during the Effectiveness Period, the number of Registrable Securities at any time exceeds 100% of the number of shares
of Common Stock then registered in a Registration Statement, then the Company shall file as soon as reasonably practicable, but
in any case prior to the applicable Filing Date, an additional Registration Statement covering the resale by the Holders of not
less than the number of such Registrable Securities.


 


(d)              
Notify the Holders of Registrable Securities to be sold (which notice shall, pursuant to clauses (iii) through (vi) hereof,
be accompanied by an instruction to suspend the use of the Prospectus until the requisite changes have been made) as promptly
as reasonably possible (and, in the case of (i)(A) below, not less than one (1) Trading Day prior to such filing) and (if requested
by any such Person) confirm such notice in writing no later than one (1) Trading Day following the day (i)(A) when a Prospectus
or any Prospectus supplement or post-effective amendment to a Registration Statement is proposed to be filed, (B) when the Commission
notifies the Company whether there will be a “review” of such Registration Statement and whenever the Commission comments
in writing on such Registration Statement, and (C) with respect to a Registration Statement or any post-effective amendment, when
the same has become effective, (ii) of any request by the Commission or any other federal or state governmental authority for
amendments or supplements to a Registration Statement or Prospectus or for additional information, (iii) of the issuance by the
Commission or any other federal or state governmental authority of any stop order suspending the effectiveness of a Registration
Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose, (iv) of the
receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification
of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such
purpose, (v) of the occurrence of any event or passage of time that makes the financial statements included in a Registration
Statement ineligible for inclusion therein or any statement made in a Registration Statement or Prospectus or any document incorporated
or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to a Registration
Statement, Prospectus or other documents so that, in the case of a Registration Statement or the Prospectus, as the case may be,
it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and (vi) of
the occurrence or existence of any pending corporate development with respect to the Company that the Company believes may be
material and that, in the determination of the Company, makes it not in the best interest of the Company to allow continued availability
of a Registration Statement or Prospectus; provided, however, that in no event shall any such notice contain any
information which would constitute material, non-public information regarding the Company or any of its Subsidiaries.


 






    8


     


    

 


(e)              
Use its best efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order stopping or suspending
the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of
any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable moment.


 


(f)               
Furnish to each Holder, without charge, at least one conformed copy of each such Registration Statement and each amendment
thereto, including financial statements and schedules, all documents incorporated or deemed to be incorporated therein by reference
to the extent requested by such Person, and all exhibits to the extent requested by such Person (including those previously furnished
or incorporated by reference) promptly after the filing of such documents with the Commission; provided, that any such item which
is available on the EDGAR system (or successor thereto) need not be furnished in physical form.


 


(g)              
Subject to the terms of this Agreement, the Company hereby consents to the use of such Prospectus and each amendment or
supplement thereto by each of the selling Holders in connection with the offering and sale of the Registrable Securities covered
by such Prospectus and any amendment or supplement thereto, except after the giving of any notice pursuant to Section 3(d).


 


(h)              
 Prior to any resale of Registrable Securities by a Holder, use its commercially reasonable efforts to register or qualify
or cooperate with the selling Holders in connection with the registration or qualification (or exemption from the Registration
or qualification) of such Registrable Securities for the resale by the Holder under the securities or Blue Sky laws of such jurisdictions
within the United States as any Holder reasonably requests in writing, to keep each registration or qualification (or exemption
therefrom) effective during the Effectiveness Period and to do any and all other acts or things reasonably necessary to enable
the disposition in such jurisdictions of the Registrable Securities covered by each Registration Statement, provided that the
Company shall not be required to qualify generally to do business in any jurisdiction where it is not then so qualified, subject
the Company to any material tax in any such jurisdiction where it is not then so subject or file a general consent to service
of process in any such jurisdiction.


 


(i)                
If requested by a Holder, cooperate with such Holder to facilitate the timely preparation and delivery of certificates
representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall
be free, to the extent permitted by the Purchase Agreement, of all restrictive legends, and to enable such Registrable Securities
to be in such denominations and registered in such names as any such Holder may request.


 






    9


     


    

 


(j)                
Upon the occurrence of any event contemplated by Section 3(d), as promptly as reasonably possible under the circumstances
taking into account the Company’s good faith assessment of any adverse consequences to the Company and its stockholders
of the premature disclosure of such event, prepare a supplement or amendment, including a post-effective amendment, to a Registration
Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference,
and file any other required document so that, as thereafter delivered, neither a Registration Statement nor such Prospectus will
contain an 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. If the Company notifies
the Holders in accordance with clauses (iii) through (vi) of Section 3(d) above to suspend the use of any Prospectus until the
requisite changes to such Prospectus have been made, then the Holders shall suspend use of such Prospectus. The Company will use
its best efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable. The Company shall be entitled
to exercise its right under this Section 3(j) to suspend the availability of a Registration Statement and Prospectus, subject
to the payment of partial liquidated damages otherwise required pursuant to Section 2(d), for a period not to exceed 60 calendar
days (which need not be consecutive days) in any 12-month period.


 


(k)              
Otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the Commission under
the Securities Act and the Exchange Act, including, without limitation, Rule 172 under the Securities Act, file any final Prospectus,
including any supplement or amendment thereof, with the Commission pursuant to Rule 424 under the Securities Act, promptly inform
the Holders in writing if, at any time during the Effectiveness Period, the Company does not satisfy the conditions specified
in Rule 172 and, as a result thereof, the Holders are required to deliver a Prospectus in connection with any disposition of Registrable
Securities and take such other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities
hereunder.


 


(l)                
The Company shall use its best efforts to maintain eligibility for use of Form F-3 (or any successor form thereto) for
the registration of the resale of Registrable Securities.


 


(m)            
The Company may require each selling Holder to furnish to the Company a certified statement as to the number of shares
of Common Stock beneficially owned by such Holder and, if required by the Commission, the natural persons thereof that have voting
and dispositive control over the shares. During any periods that the Company is unable to meet its obligations hereunder with
respect to the registration of the Registrable Securities solely because any Holder fails to furnish such information within three
Trading Days of the Company’s request, any liquidated damages that are accruing at such time as to such Holder only shall
be tolled and any Event that may otherwise occur solely because of such delay shall be suspended as to such Holder only, until
such information is delivered to the Company.


 






    10


     


    

 


4.        Registration

borne by the Company whether or not any Registrable Securities are sold pursuant to a Registration Statement. The fees and expenses
referred to in the foregoing sentence shall include, without limitation, (i) all registration and filing fees (including, without
limitation, fees and expenses of the Company’s counsel and independent registered public accountants) (A) with respect to
filings made with the Commission, (B) with respect to filings required to be made with any Trading Market on which the Common

Blue Sky qualifications or exemptions of the Registrable Securities), (ii) printing expenses (including, without limitation, expenses
of printing certificates for Registrable Securities), (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements
of counsel for the Company, (v) Securities Act liability insurance, if the Company so desires such insurance, and (vi) fees and

this Agreement. In addition, the Company shall be responsible for all of its internal expenses incurred in connection with the
consummation of the transactions contemplated by this Agreement (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expense of any annual audit and the fees and expenses incurred
in connection with the listing of the Registrable Securities on any securities exchange as required hereunder. In no event shall
the Company be responsible for any broker or similar commissions of any Holder or, except to the extent provided for in the Transaction
Documents, any legal fees or other costs of the Holders.

and hold harmless each Holder, the officers, directors, members, partners, agents, brokers (including brokers who offer and sell
Registrable Securities as principal as a result of a pledge or any failure to perform under a margin call of Common Stock), investment

untrue statement of a material fact contained in a Registration Statement, any Prospectus or any form of prospectus or in any
amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission
of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or
supplement thereto, in light of the circumstances under which they were made) not misleading or (2) any violation or alleged violation
by the Company of the Securities Act, the Exchange Act or any state securities law, or any rule or regulation thereunder, in connection
with the performance of its obligations under this Agreement, except to the extent, but only to the extent, that (i) such untrue
statements or omissions are based solely upon information regarding such Holder furnished in writing to the Company by such Holder
expressly for use therein, or to the extent that such information relates to such Holder or such Holder’s proposed method
of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for use
in a Registration Statement, such Prospectus or in any amendment or supplement thereto (it being understood that the Holder has
approved Annex A hereto for this purpose) or (ii) in the case of an occurrence of an event of the type specified in Section 3(d)(iii)-(vi),
the use by such Holder of an outdated, defective or otherwise unavailable Prospectus after the Company has notified such Holder
in writing that the Prospectus is outdated, defective or otherwise unavailable for use by such Holder and prior to the receipt
by such Holder of the Advice contemplated in Section 6(d). The Company shall notify the Holders promptly of the institution, threat
or assertion of any Proceeding arising from or in connection with the transactions contemplated by this Agreement of which the
Company is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of
such indemnified person and shall survive the transfer of any Registrable Securities by any of the Holders in accordance with
Section 6(h).


 






    12


     


    

 


(b)              
Indemnification by Holders. Each Holder shall, severally and not jointly, indemnify and hold harmless the Company,
its directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities
Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses, as incurred, to the extent arising out of or based solely
upon: any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus, or in
any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged
omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus
or supplement thereto, in light of the circumstances under which they were made) not misleading (i) to the extent, but only to
the extent, that such untrue statement or omission is contained in any information so furnished in writing by such Holder to the
Company expressly for inclusion in such Registration Statement or such Prospectus or (ii) to the extent, but only to the extent,
that such information relates to such Holder’s information provided in the Selling Stockholder Questionnaire or the proposed
method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for
use in a Registration Statement (it being understood that the Holder has approved Annex A hereto for this purpose), such Prospectus
or in any amendment or supplement thereto. In no event shall the liability of a selling Holder be greater in amount than the dollar
amount of the proceeds (net of all expenses paid by such Holder in connection with any claim relating to this Section 5 and the
amount of any damages such Holder has otherwise been required to pay by reason of such untrue statement or omission) received
by such Holder upon the sale of the Registrable Securities included in the Registration Statement giving rise to such indemnification
obligation.


 






    13


     


    

 


(c)              
Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled
to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from
whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall have the right
to assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment
of all fees and expenses incurred in connection with defense thereof, provided that the failure of any Indemnified Party to give
such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and
only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject
to appeal or further review) that such failure shall have materially and adversely prejudiced the Indemnifying Party.


 


An Indemnified
Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the
fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (1) the Indemnifying Party
has agreed in writing to pay such fees and expenses, (2) the Indemnifying Party shall have failed promptly to assume the defense
of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding, or (3) the
named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying
Party, and counsel to the Indemnified Party shall reasonably believe that a material conflict of interest is likely to exist if
the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party
notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party,
the Indemnifying Party shall not have the right to assume the defense thereof and the reasonable fees and expenses of no more
than one separate counsel shall be at the expense of the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which consent shall not be unreasonably withheld or delayed.
No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending
Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such
Indemnified Party from all liability on claims that are the subject matter of such Proceeding.


 






    14


     


    

 


Subject
to the terms of this Agreement, all reasonable fees and expenses of the Indemnified Party (including reasonable fees and expenses
to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with
this Section) shall be paid to the Indemnified Party, as incurred, within ten Trading Days of written notice thereof to the Indemnifying
Party, provided that the Indemnified Party shall promptly reimburse the Indemnifying Party for that portion of such fees and expenses
applicable to such actions for which such Indemnified Party is finally determined by a court of competent jurisdiction (which
determination is not subject to appeal or further review) not to be entitled to indemnification hereunder.


 


(d)              
Contribution. If the indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party or insufficient
to hold an Indemnified Party harmless for any Losses, then each Indemnifying Party shall contribute to the amount paid or payable
by such Indemnified Party, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified
Party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable
considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among
other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission
or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party
or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent
such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include,
subject to the limitations set forth in this Agreement, any reasonable attorneys’ or other fees or expenses incurred by
such party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if
the indemnification provided for in this Section was available to such party in accordance with its terms.


 


The parties
hereto agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the
immediately preceding paragraph. In no event shall the contribution obligation of a Holder of Registrable Securities be greater
in amount than the dollar amount of the proceeds (net of all expenses paid by such Holder in connection with any claim relating
to this Section 5 and the amount of any damages such Holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission) received by it upon the sale of the Registrable Securities giving rise to such
contribution obligation.


 


The indemnity
and contribution agreements contained in this Section are in addition to any liability that the Indemnifying Parties may have
to the Indemnified Parties.


 






    15


     


    

 


6.        Miscellaneous.


 


(a)              
Remedies. In the event of a breach by the Company or by a Holder of any of their respective obligations under this
Agreement, each Holder or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law
and under this Agreement, including recovery of damages, shall be entitled to specific performance of its rights under this Agreement.
Each of the Company and each Holder agrees that monetary damages would not provide adequate compensation for any losses incurred
by reason of a breach by it of any of the provisions of this Agreement and hereby further agrees that, in the event of any action
for specific performance in respect of such breach, it shall not assert or shall waive the defense that a remedy at law would
be adequate.


 


(b)              
No Piggyback on Registrations; Prohibition on Filing Other Registration Statements. Neither the Company nor any
of its security holders (other than the Holders in such capacity pursuant hereto) may include securities of the Company in any
Registration Statements other than the Registrable Securities. The Company shall not file any other registration statements until
all Registrable Securities are registered pursuant to a Registration Statement that is declared effective by the Commission, provided
that this Section 6(b) shall not prohibit the Company from filing amendments to registration statements filed prior to the date
of this Agreement.


 


(c)              
[RESERVED]


 


(d)              
Discontinued Disposition. By its acquisition of Registrable Securities, each Holder agrees that, upon receipt of
a notice from the Company of the occurrence of any event of the kind described in Section 3(d)(iii) through (vi), such Holder
will forthwith discontinue disposition of such Registrable Securities under a Registration Statement until it is advised in writing
(the “Advice”) by the Company that the use of the applicable Prospectus (as it may have been supplemented or
amended) may be resumed. The Company will use its best efforts to ensure that the use of the Prospectus may be resumed as promptly
as is practicable. The Company agrees and acknowledges that any periods during which the Holder is required to discontinue the
disposition of the Registrable Securities hereunder shall be subject to the provisions of Section 2(d).


 






    16


     


    

 


(e)              
Piggy-Back Registrations. If, at any time during the Effectiveness Period, there is not an effective Registration
Statement covering all of the Registrable Securities, and in particular the Warrant Shares, and the Company shall determine to
prepare and file with the Commission a registration statement relating to an offering for its own account or the account of others
under the Securities Act of any of its equity securities, other than on Form S-4 or Form S-8 (each as promulgated under the Securities
Act) or their then equivalents relating to equity securities to be issued solely in connection with any acquisition of any entity
or business or equity securities issuable in connection with the Company’s stock option or other employee benefit plans,
then the Company shall deliver to each Holder a written notice of such determination and, if within fifteen days after the date
of the delivery of such notice, any such Holder shall so request in writing, the Company shall include in such registration statement
all or any part of such Registrable Securities such Holder requests to be registered; provided, however, that the
Company shall not be required to register any Registrable Securities pursuant to this Section 6(e) that are eligible for resale
pursuant to Rule 144 (without volume restrictions or current public information requirements) promulgated by the Commission pursuant
to the Securities Act or that are the subject of a then effective Registration Statement that is available for resales or other
dispositions by such Holder.


 


(f)               
Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be
amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the
same shall be in writing and signed by the Company and the Holders of 50.1% or more of the then outstanding Registrable Securities
(for purposes of clarification, this includes any Registrable Securities issuable upon exercise or conversion of any Security),
provided that, if any amendment, modification or waiver disproportionately and adversely impacts a Holder (or group of Holders),
the consent of such disproportionately impacted Holder (or group of Holders) shall be required. If a Registration Statement does
not register all of the Registrable Securities pursuant to a waiver or amendment done in compliance with the previous sentence,
then the number of Registrable Securities to be registered for each Holder shall be reduced pro rata among all Holders and each
Holder shall have the right to designate which of its Registrable Securities shall be omitted from such Registration Statement.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates
exclusively to the rights of a Holder or some Holders and that does not directly or indirectly affect the rights of other Holders
may be given only by such Holder or Holders of all of the Registrable Securities to which such waiver or consent relates; provided,
however, that the provisions of this sentence may not be amended, modified, or supplemented except in accordance with the
provisions of the first sentence of this Section 6(f). No consideration shall be offered or paid to any Person to amend or consent
to a waiver or modification of any provision of this Agreement unless the same consideration also is offered to all of the parties
to this Agreement.


 


(g)              
Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder
shall be delivered as set forth in the Purchase Agreement.


 






    17


     


    

 


(h)              
Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and permitted
assigns of each of the parties and shall inure to the benefit of each Holder. The Company may not assign (except by merger) its
rights or obligations hereunder without the prior written consent of all of the Holders of the then outstanding Registrable Securities.
Each Holder may assign their respective rights hereunder in the manner and to the Persons as permitted under Section 5.8 of the
Purchase Agreement.


 


(i)                
No Inconsistent Agreements. Neither the Company nor any of its Subsidiaries has entered, as of the date hereof,
nor shall the Company or any of its Subsidiaries, on or after the date of this Agreement, enter into any agreement with respect
to its securities, that would have the effect of impairing the rights granted to the Holders in this Agreement or otherwise conflicts
with the provisions hereof. Except as set forth on Schedule 6(i), neither the Company nor any of its Subsidiaries has previously
entered into any agreement granting any registration rights with respect to any of its securities to any Person that have not
been satisfied in full.


 


(j)                
Execution and Counterparts. This Agreement may be executed in two or more counterparts, all of which when taken
together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each
party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event
that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such
signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with
the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.


 


(k)              
Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement
shall be determined in accordance with the provisions of the Purchase Agreement.


 


(l)                
Cumulative Remedies. The remedies provided herein are cumulative and not exclusive of any other remedies provided
by law.


 


(m)            
Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent
jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions
set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially
the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to
be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without
including any of such that may be hereafter declared invalid, illegal, void or unenforceable.


 






    18


     


    

 


(n)              
Headings. The headings in this Agreement are for convenience only, do not constitute a part of the Agreement and
shall not be deemed to limit or affect any of the provisions hereof.


 


(o)              
Independent Nature of Holders’ Obligations and Rights. The obligations of each Holder hereunder are several
and not joint with the obligations of any other Holder hereunder, and no Holder shall be responsible in any way for the performance
of the obligations of any other Holder hereunder. Nothing contained herein or in any other agreement or document delivered at
any closing, and no action taken by any Holder pursuant hereto or thereto, shall be deemed to constitute the Holders as a partnership,
an association, a joint venture or any other kind of group or entity, or create a presumption that the Holders are in any way
acting in concert or as a group or entity with respect to such obligations or the transactions contemplated by this Agreement
or any other matters, and the Company acknowledges that the Holders are not acting in concert or as a group, and the Company shall
not assert any such claim, with respect to such obligations or transactions. Each Holder shall be entitled to protect and enforce
its rights, including without limitation the rights arising out of this Agreement, and it shall not be necessary for any other
Holder to be joined as an additional party in any proceeding for such purpose. The use of a single agreement with respect to the
obligations of the Company contained was solely in the control of the Company, not the action or decision of any Holder, and was
done solely for the convenience of the Company and not because it was required or requested to do so by any Holder. It is expressly
understood and agreed that each provision contained in this Agreement is between the Company and a Holder, solely, and not between
the Company and the Holders collectively and not between and among Holders.

Annex A


 


Plan of Distribution


 


Each Selling Stockholder
(the “Selling Stockholders”) of the securities and any of their pledgees, assignees and successors-in-interest
may, from time to time, sell any or all of their securities covered hereby on the principal Trading Market or any other stock
exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed
or negotiated prices. A Selling Stockholder may use any one or more of the following methods when selling securities:


 


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



 


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



 


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



 


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



 


		·	privately negotiated
                                         transactions;



 


		·	settlement
                                         of short sales;



 


		·	in transactions
                                         through broker-dealers that agree with the Selling Stockholders to sell a specified number
                                         of such securities at a stipulated price per security;



 


		·	through the
                                         writing or settlement of options or other hedging transactions, whether through an options
                                         exchange or otherwise;



 


		·	a combination
                                         of any such methods of sale; or



 


		·	any other method
                                         permitted pursuant to applicable law.



 


The Selling Stockholders
may also sell securities under Rule 144 or any other exemption from registration under the Securities Act of 1933, as amended
(the “Securities Act”), if available, rather than under this prospectus.


 


Broker-dealers engaged
by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions
or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser)
in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction
not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction
a markup or markdown in compliance with FINRA IM-2440.


 






     


     


    

 


In connection with
the sale of the securities or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers
or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions
they assume. The Selling Stockholders may also sell securities short and deliver these securities to close out their short positions,
or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter
into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities
which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which
securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended
to reflect such transaction).


 


The Selling Stockholders
and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within
the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers
or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts
under the Securities Act. Each Selling Stockholder has informed the Company that it does not have any written or oral agreement
or understanding, directly or indirectly, with any person to distribute the securities.


 


The Company is required
to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed
to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the
Securities Act.


 


We agreed to keep
this prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling Stockholders
without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement
for the Company to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule
of similar effect or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act
or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers
if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not
be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or
qualification requirement is available and is complied with.


 


Under applicable rules
and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously
engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation
M, prior to the commencement of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions
of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases
and sales of the common stock by the Selling Stockholders or any other person. We will make copies of this prospectus available
to the Selling Stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior
to the time of the sale (including by compliance with Rule 172 under the Securities Act).

SELLING SHAREHOLDERS


 


The common stock being
offered by the selling shareholders are those previously issued to the selling shareholders, and those issuable to the selling
shareholders, upon exercise of the warrants. For additional information regarding the issuances of those shares of common stock
and warrants, see "Private Placement of Common Shares and Warrants" above. We are registering the shares of common stock
in order to permit the selling shareholders to offer the shares for resale from time to time. Except for the ownership of the
shares of common stock and the warrants, the selling shareholders have not had any material relationship with us within the past
three years.


 


The table below lists
the selling shareholders and other information regarding the beneficial ownership of the shares of common stock by each of the
selling shareholders. The second column lists the number of shares of common stock beneficially owned by each selling shareholder,
based on its ownership of the shares of common stock and warrants, as of ________, 2020, assuming exercise of the warrants held
by the selling shareholders on that date, without regard to any limitations on exercises.


 


The third column lists
the shares of common stock being offered by this prospectus by the selling shareholders.


 


In accordance with
the terms of a registration rights agreement with the selling shareholders, this prospectus generally covers the resale of the
sum of (i) the number of shares of common stock issued to the selling shareholders in the __________________ and (ii) the maximum
number of shares of common stock issuable upon exercise of the related warrants, determined as if the outstanding warrants were
exercised in full as of the trading day immediately preceding the date this registration statement was initially filed with the
SEC, each as of the trading day immediately preceding the applicable date of determination and all subject to adjustment as provided
in the registration right agreement, without regard to any limitations on the exercise of the warrants. The fourth column assumes
the sale of all of the shares offered by the selling shareholders pursuant to this prospectus.


 


Under the terms of
the warrants, a selling shareholder may not exercise the warrants to the extent such exercise would cause such selling shareholder,
together with its affiliates and attribution parties, to beneficially own a number of shares of common stock which would exceed
[4.99%][9.99%]1 of our then outstanding
common stock following such exercise, excluding for purposes of such determination shares of common stock issuable upon exercise
of the warrants which have not been exercised. The number of shares in the second column does not reflect this limitation. The
selling shareholders may sell all, some or none of their shares in this offering. See "Plan of Distribution."
