(a)The Company
shall prepare and file with the Commission the Initial Registration Statement covering the resale of all of the Registrable Securities
that are not then registered on an effective Registration Statement. The Company shall have
ten (10) days to file the Initial Registration Statement with the Commission. The Registration Statement filed hereunder
shall be on Form S-1 or Form S-3 and shall contain substantially the “Plan of Distribution” attached hereto
as Annex A. If Form S-1 or Form S-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 S-1 or Form S-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 S-1 or Form
S-3 covering the Registrable Securities has been declared effective by the Commission. Subject
to the limitations set forth in Sections 2(c), 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
within forty-five (45) days 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 all Registrable
Securities covered by such Registration Statement (i) have been sold, thereunder or pursuant to Rule 144, or (ii) six (6) months
after the Registrable Securities 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 Holder (the “Effectiveness Period”). The Company shall telephonically request effectiveness

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(g).


 






    	 	3	 



     


    

 


(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 S-1 or Form S-3 or such other form available to register for resale the
Registrable Securities as a secondary offering, subject to the provisions of Section 2(g); with respect to filing on Form S-1
or Form S-3 or other appropriate form, and subject to the provisions of Section 2(g) 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.


 


(c)Reserved.


 


(d)Piggyback
Registration. 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 2(d) 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. 


 






    	 	4	 



     


    

 


(e)Allocation
of Shares. In connection with any offering under Section 2(d) involving an underwriting, the Company shall not be required
to include any Registrable Securities in such underwriting unless the Holder thereof accepts the terms of the underwriting as
agreed upon between the Company and the underwriters selected by it. Further, if the managing underwriter advises the Company
that, in its view, the number of Registrable Securities requested to be included in such registration exceeds the “Maximum
Offering Size” (which shall mean the largest aggregate number of shares which can be sold without having a material adverse
effect on such offering, as determined by the managing underwriter), the Company will include in such registration, in the following
priority, up to the Maximum Offering Size: first, so many shares of Common Stock proposed to be registered by the Company as would
not cause the offering to exceed the Maximum Offering Size; and second, any Registrable Securities requested to be included in
such registration by the Purchaser, allocated, if necessary, pro rata on the basis of their relative number of Registrable Securities
so held. 


 


(f)Notwithstanding
any other provision of this Agreement and subject to the payment of liquidated damages pursuant to Section 2(g), 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 by any Person other
                                         than a Holder; 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);
                                         and



 


		c.	Third,
                                         the Company shall reduce Registrable Securities represented by Conversion Shares (applied,
                                         in the case that some Conversion Shares may be registered, to the Holders on a pro rata
                                         basis based on the total number of unregistered Conversion 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 S-1 or Form S-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	 



     


    

 


(g)If: (i)
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 (5) 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 (ii) 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 (iii) 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 (iv) 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 Holder
is 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 clause (i)
the date on which such five (5) Trading Day period is exceeded, and for purpose of clause (ii) the date which such ten (10) calendar
day period is exceeded, and for purpose of clause (iii) the date on which such Event occurs, and for purpose of clause (iv) 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 Holder 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 Initial Registration Statement is not filed on or prior to the time periods described in Section
2(a) (if the Company files the Initial Registration Statement without affording the Holder 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) (the “Filing
Event Date”), then in addition to any other rights the Holder may have hereunder or under applicable law, 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. Additionally, for each month monthly
anniversary of such Filing Event Date until the Initial Registration Statement is filed, 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 1.0% 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.

(h)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. Notwithstanding the above, the Company shall not be obligated to provide
the Holders advance copies of any universal shelf registration statement registering securities in addition to those required
hereunder, or any Prospectus prepared thereto. 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, within
thirty (30) days, 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, 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) The
Company shall cooperate with any broker-dealer through which a Holder proposes to resell its Registrable Securities in effecting
a filing with the FINRA Corporate Financing Department pursuant to FINRA Rule 5110, as requested by any such Holder, and the Company
shall pay the filing fee required by such filing within two (2) Business Days of request therefor.


 


(i)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.


 






    	 	9	 



     


    

 


(j)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.


 


(k)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(k) to suspend the availability of a Registration Statement and Prospectus, subject to the payment
of partial liquidated damages otherwise required pursuant to Section 2(g), for a period not to exceed sixty (60) calendar days
(which need not be consecutive days) in any 12-month period.


 


(l)Comply
with all applicable rules and regulations of the Commission.


 


(m)The Company
shall use its best efforts to maintain eligibility for use of Form S-1 or Form S-3 (or any successor form thereto) for the registration
of the resale of Registrable Securities.


 


(n)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.

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 Holder.

5. Indemnification.


 


(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 of them, each Person who controls any such Holder (within the meaning of Section 15 of the Securities
Act or Section 20 of the 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 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), but only if and to the extent that following the receipt of the Advice
the misstatement or omission giving rise to such Loss would have been corrected. 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(g).


  


(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.


 






    	 	12	 



     


    

 


(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.


 






    	 	13	 



     


    

 


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.


 






    	 	14	 



     


    

 


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 and no bond or
similar items shall be requested to be posted.


 


(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),
(i) shall not prohibit the Company from filing amendments to registration statements filed prior to the date of this Agreement
and (ii) shall not prohibit the Company from filing a registration statement on Form S-1 or Form S-3 for a primary offering by
the Company, provided that the Company makes no offering of securities pursuant to such shelf registration statement prior to
the effective date of the Registration Statement required hereunder that includes all of the Registrable Securities.


 


(c)Compliance.
Each Holder covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable
to it (unless an exemption therefrom is available) in connection with sales of Registrable Securities pursuant to a Registration
Statement.


 


(d)Discontinued
Disposition. By its acquisition of Registrable Securities, the 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.


 


(e)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 67% 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). 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	 



     


    

 


(f)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.


 


(g)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.


 


(h)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(h), 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.


 


(i)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.


 


(j)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.


 


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


 


(l)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.


 






    	 	16	 



     


    

 


(m)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.


 


(n)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 OTC Bulletin Board 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 securities 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).
