2.                       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 S-1 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. Eastern 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. Eastern 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.


 


(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, 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;



 






    4


    


    

 


		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); and



 


		c.	Third, the Company shall reduce Registrable Securities represented
by Pre-Funded Warrant Shares (applied, in the case that some Pre-Funded Warrant Shares may be registered, to the Holders on a pro rata
basis based on the total number of unregistered Pre-Funded 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 to register for resale those Registrable
Securities that were not registered for resale on the Initial Registration Statement, as amended.


 


(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 The parties agree
that the maximum aggregate liquidated damages payable to a Holder under this Agreement shall be 12.0% of 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.


 






    5


    


    

 


(e)            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 four (4) Trading Days
prior to the Filing Date or by the end of the second (2nd) Trading Day following the date on which such Holder receives draft materials
in accordance with this Section.


 






    6


    


    

 


(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.


 


(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.


 






    7


    


    

 


(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, 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.


 


(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).


 






    8


    


    

 


(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.


 


(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.


 






    9


    


    

 


(l)             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.


 


4.                      Registration
Expenses. All fees and expenses incident to the performance of or compliance with, this Agreement by the Company shall be 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 Stock is then listed
for trading, and (C) in compliance with applicable state securities or Blue Sky laws reasonably agreed to by the Company in writing
(including, without limitation, fees and disbursements of counsel for the Company in connection with 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 expenses of all other Persons retained by the
Company in connection with the consummation of the transactions contemplated by 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.

(a)            Indemnification
by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify 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 advisors and employees (and any other Persons
with a functionally equivalent role of a Person holding such titles, notwithstanding a lack of such title or any other title) of each

Exchange Act) and the officers, directors, members, stockholders, partners, agents and employees (and any other Persons with a functionally
equivalent role of a Person holding such titles, notwithstanding a lack of such title or any other title) of each such controlling Person,
to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including,
without limitation, reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, arising out
of or relating to (1) any untrue or alleged 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

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),

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.


 


(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.


 






    12


    


    

 


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.


 


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.


 






    13


    


    

 


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.


 


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 Except as set forth on Schedule 6(b) attached hereto, 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.


 


(c)           [Reserved]


 






    14


    


    

 


(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).


 


(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 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 51% 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.


 






    15


    


    

 


(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.


 


(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 5.7 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.


 






    16


    


    

 


(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.


 


(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.


 






    2


     


    

 


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 and the pre-funded warrants. For additional information regarding the issuances of those shares of common stock,
warrants and pre-funded warrants, see "Private Placement of Securities" 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, the warrants and the pre-funded 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, warrants and pre-funded warrants, as of ________, 2021, assuming exercise of the warrants and pre-funded 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 pursuant to the Purchase Agreement and (ii) the maximum number
of shares of common stock issuable upon exercise of the related warrants and pre-funded warrants, determined as if the outstanding warrants
and pre-funded 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 and the pre-funded
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
and pre-funded warrants, a selling shareholder may not exercise the warrants or pre-funded 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]% 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 and pre-funded 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."
