2.
Shelf Registration.


 


(a)               
On or prior to each Filing Date, the Company shall prepare and file with the Commission a Registration Statement covering the
resale of all of the Registrable Securities that are not then registered on an effective Registration Statement for an offering
to be made on a continuous basis pursuant to Rule 415. Each Registration Statement filed hereunder shall be on Form S-3 (except
if the Company is not then eligible to register for resale the Registrable Securities on Form S-3, in which case such registration
shall be on another appropriate form in accordance herewith, subject to the provisions of Section 2(e)) and shall contain (unless
otherwise directed by at least 85% in interest of the Holders) substantially the “Plan of Distribution” attached
hereto as Annex A; 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, on 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(e); 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)               
Notwithstanding any other provision of this Agreement and subject to the payment of liquidated damages pursuant to Section 2(d),
if the Commission or any SEC Guidance sets forth a limitation on the number of Registrable Securities permitted to be registered
on a particular Registration Statement as a secondary offering (and notwithstanding that the Company used diligent efforts to
advocate with the Commission for the registration of all or a greater portion of Registrable Securities), unless otherwise directed
in writing by a Holder as to its Registrable Securities, the number of Registrable Securities to be registered on such Registration
Statement will be reduced as follows:


 


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



 


		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-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.


 


(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 1.5% of the aggregate purchase
price 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 6% 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.


 


(e)               
If 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-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-3 covering the Registrable Securities has been
declared effective by the Commission.


 


(f)               
Notwithstanding the registration obligations set forth in Section 2(a), if the Commission informs the Company that some or all
of the Registrable Securities identified in clause (d) and/or clause (e) of the definition of Registrable Securities cannot, as
a result of the application of Rule 415, be registered until such time as such Registrable Securities become definitely issuable
and/or the number of such Registrable Securities becomes known, 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,
or such additional Registration Statements, as and when such Registrable Securities become subject to registration. The failure
of the Initial Registration Statement to include Registrable Securities identified in clause (d) and/or clause (e) in the definition
of Registrable Securities when it becomes effective if the number thereof is not known or such securities are not then definitively
issuable at such time shall not subject the Company to damages with respect thereto under Section 2(d) of this Agreement.


 


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 67% or more 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.


 


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


 


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


 


(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.


 


(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(d), for a period
not to exceed 60 calendar days (which need not be consecutive days) in any 12-month period.


 


(l)                
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.


 


(m)            
The Company shall use its best efforts to maintain eligibility for use of 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.

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.


 


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(h).


 


(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: (x) such Holder’s failure to comply with any applicable prospectus delivery requirements of the Securities Act through
no fault of the Company or (y) 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 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 or (iii) in the case of an occurrence of an event of the type specified in Section 3(d)(iii)-(vi), to the extent, but
only to the extent, related to 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. In no event
shall the liability of any selling Holder under this Section 5(b) be greater in amount than the dollar amount of the net proceeds
received by such Holder upon the sale of the Registrable Securities 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.


 


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.


 


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. Notwithstanding the provisions of this Section 5(d), no Holder shall be required to
contribute pursuant to this Section 5(d), in the aggregate, any amount in excess of the amount by which the net proceeds actually
received by such Holder from the sale of the Registrable Securities subject to the Proceeding exceeds the amount of any damages
that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged
omission.


 


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; Prohibition on Filing Other Registration Statements. 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. The Company
shall not file any other registration statements until all Registrable Securities are registered pursuant to a Registration Statement
that is declared effective by the Commission, provided that this Section 6(b) shall not prohibit the Company from filing amendments
to registration statements filed prior to the date of this Agreement.


 


(c)               
[RESERVED]


 


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


 


(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 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.


 


(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.


 


(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

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 OTCQB 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 entered into after the effective date of the registration statement of
                                         which this prospectus is a part;



		•	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 under the Securities Act of 1933, as amended (the “Securities
Act”), if available, rather than under this prospectus.


 


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


 


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


 


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


 


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


 


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


 


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