2.
REGISTRATION.

 

(a)
Following the Closing Date, but no later than sixty (60) days following the Closing Date (such date, the “Mandatory Shelf
Filing Date”), the Issuer shall prepare and use its commercially reasonable efforts to file a Registration Statement
(a “Shelf Registration Statement”) with the SEC providing for registration and resale, on a continuous or delayed
basis pursuant to Rule 415, of all the Registrable Securities then outstanding from time to time. The Issuer shall use its commercially
reasonable efforts to cause the Shelf Registration Statement to be declared effective under the Securities Act by the SEC as soon
as reasonably practicable after the Mandatory Shelf Filing Date, but in any event no later than the earlier of (i) if the Shelf
Registration Statement is subject to review by the SEC, one hundred and twenty (120) days following the Closing Date, and (ii)
if the Shelf Registration Statement is not subject to review by the SEC, ten (10) days following the date of receipt of such notice
from the SEC (such earlier date, the “Effectiveness Deadline”). The Issuer shall use its commercially reasonable
efforts to keep the Shelf Registration Statement continuously effective under the Securities Act and to be supplemented and amended
to ensure that the Shelf Registration Statement is available for the resale of all Registrable Securities by the Holders until
the date when all of the Registrable Securities covered by such Shelf Registration Statement have been sold (the “Effectiveness
Period”). As soon as practicable following the date that the Shelf Registration Statement becomes effective, but in
any event within two (2) Business Days of such date, the Issuer shall provide the Holders with written notice of the effectiveness
of the Shelf Registration Statement.

 

(b)
If a Holder or Holders of at least twenty-five percent (25%) of the Registrable Securities then outstanding elect to distribute
the Registrable Securities covered by the Shelf Registration Statement in an underwritten offering (the “Underwritten
Offering”), they shall so advise the Issuer, and the Issuer shall promptly, but in no event later than five (5) Business
Days after the request from the requesting Holders, provide notice to the other Holders of the proposed Underwritten Offering.
The Holders of a majority of the Registrable Securities initially requesting the Underwritten Offering shall select the investment
banking firm or firms to act as the managing underwriter or underwriters in connection with such offering; provided, that
such selection shall be subject to the consent of the Issuer, which consent shall not be unreasonably withheld, conditioned or
delayed. The Issuer shall not be required to effect an Underwritten Offering more than three (3) times in the aggregate for the
Holders as a group; provided, that an Underwritten Offering shall not count against such limit unless and until the Holder(s)
requesting such registration are able to sell at least seventy-five percent (75%) of the Registrable Securities requested to be
included in such Underwritten Offering.

 

    	 3

    	 

    

 

(c)
The Issuer shall not be obligated to effect any Underwritten Offering within a hundred and twenty (120) days after the effective
date of a previous Underwritten Offering, a previous Piggyback Registration in which Holders sold all of the shares of Registrable
Securities requested to be included therein or a demand registration effected pursuant to the Existing Registration Rights Agreement.
The Issuer may postpone for up to twenty (20) Business Days any Underwritten Offering if the Issuer’s Board of Directors
determines in its reasonable good faith judgment that such Underwritten Offering would (i) materially interfere with a significant
acquisition, corporate organization or other similar transaction involving the Issuer; (ii) require premature disclosure of material
information that the Issuer has a bona fide business purpose for preserving as confidential; or (iii) render the Issuer unable
to comply with requirements under the Securities Act or Exchange Act; provided, that in such event the Holders of a majority
of the Registrable Securities initiating such Underwritten Offering shall be entitled to withdraw such request and, if such request
is withdrawn, such Underwritten Offering shall not count as one of the permitted Underwritten Offerings hereunder and the Issuer
shall pay all expenses in connection with such offering. The Issuer may delay an Underwritten Offering hereunder only twice in
any period of twelve (12) consecutive months.

 

(d)
The Issuer shall not include in any Underwritten Offering any securities which are not Registrable Securities other than the securities
owned by Existing Rights Holders without the prior written consent of the Holders of a majority of the Registrable Securities
included in such Underwritten Offering, which consent shall not be unreasonably withheld or delayed. If the managing underwriter
of the requested Underwritten Offering advises the Issuer and the Holders of Registrable Securities to be included in that Underwritten
Offering in writing that in its opinion the number of shares of Common Stock proposed to be included in the Underwritten Offering,
including all Registrable Securities and all other shares of Common Stock proposed to be included in such Underwritten Offering,
exceeds the number of shares of Common Stock which can be sold in such Underwritten Offering and/or that the number of shares
of Common Stock proposed to be included in any registration would adversely affect the price per share of the Common Stock proposed
to be sold in such Underwritten Offering, the Issuer shall include in such Underwritten Offering (i) first, (x) the number of
shares of Common Stock requested to be included by Holders of Registrable Securities who have requested an Underwritten Offering,
(y) the number of shares of Common Stock that the other Holders of Registrable Securities propose to sell, and (z) if Existing
Rights Holders elect to participate in such Underwritten Offering pursuant to the Existing Registration Rights Agreement, the
number of shares of Common Stock that such Existing Rights Holders propose to sell, pro rata (among clauses (x), (y) and (z))
in accordance with their respective requests and (ii) second, if all of the securities requested to be sold under clause (i) (the
“Clause (i) Securities”) are included the number of shares of Common Stock proposed to be included therein
by any other Persons (including shares of Common Stock to be sold for the account of the Issuer and/or other holders of Common
Stock) allocated among such Persons in such manner as they may agree. If the managing underwriter determines that less than all
of the Clause (i) Securities proposed to be sold can be included in such offering, then the Clause (i) Securities that are included
in such offering shall be allocated pro rata among the respective Holders and Existing Rights Holders, on the basis of the number
of Clause (i) Securities requested to be sold in such Underwritten Offering.

 

(e)
Notwithstanding any other provision of this Agreement, if the SEC or any SEC Guidance sets forth a limitation on the number of
Registrable Securities permitted to be registered on a particular Shelf Registration Statement as a secondary offering (and notwithstanding
that the Issuer used reasonable best efforts to advocate with the SEC for the registration of all or a greater portion of Registrable
Securities) or in any Underwritten Offering, unless otherwise directed in writing by a Holder as to its Registrable Securities,
the number of Registrable Securities to be registered on such Shelf Registration Statement will be reduced as follows:

 

	 	(i)	First,
    the Issuer shall reduce or eliminate any securities to be included other than (A) Registrable Securities held by Holders or
    (B) securities of the Issuer held by Existing Rights Holders subject to registration rights pursuant to the Existing Registration
    Rights Agreement; 

 

	 	(ii)	Second,
if further reduction is required after the elimination of all securities described in Section 2(e)(i), the Issuer shall reduce
the securities of the Issuer held by Existing Rights Holders other than the securities issued pursuant to the Subscription Agreement
(and without limiting such Existing Rights Holders’ rights under the Existing Registration Rights Agreement);

                                                          

	 	(iii)	Third,
        if further reduction is required after the elimination of all securities described in Section 2(e)(i) and (ii), the Issuer
        shall reduce the securities of the Issuer held by Existing Rights Holders issued pursuant to the Subscription Agreement
        (and without limiting such Existing Rights Holders’ rights under the Existing Registration Rights Agreement); and

         

	 	(iv)	Fourth,
if further reduction is required after the elimination of all securities described in Sections 2(e)(i), (ii) and (iii), the Issuer
shall reduce, pro rata in accordance with their respective requests, the Registrable Securities held by Holders.

 

    	 4

    	 

    

 

In
the event of a cutback hereunder, the Issuer shall give each Holder at least five (5) Trading Days prior written notice along
with the calculations as to such Holder’s allotment. In the event the Issuer amends the initial Registration Statement in
accordance with the foregoing, the Issuer will use its best efforts to file with the SEC, as promptly as allowed by the SEC or
SEC Guidance provided to the SEC or to registrants of securities in general, one or more registration statements on Form S-1 or
such other form available to register for resale those Registrable Securities that were not registered for resale on the initial
Shelf Registration Statement, as amended.

 

(f)
If (i) the Issuer has not filed a Shelf Registration Statement pursuant to Section 2(a) by the Mandatory Shelf Filing Date, or
(ii) such Shelf Registration Statement has not been declared effective by the SEC on or before the Effectiveness Deadline, (any
such failure or breach being referred to as an “Event”, and the date on which such Event occurs 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 Issuer shall pay to each Holder an amount in cash, as partial liquidated
damages and not as a penalty, equal to the product of one percent (1.0%) multiplied by the aggregate per share purchase price
paid by such Holder pursuant to the Subscription Agreement. If the Issuer fails to pay any partial liquidated damages pursuant
to this Section 2(f) in full within fifteen (15) days after the date payable, the Issuer will pay interest thereon at a rate of
twelve percent (12%) 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. In the event that the Issuer registers some but not all of the Registrable Securities, the one percent
(1.0%) of liquidated damages referred to above for any monthly period shall be reduced to equal the percentage determined by multiplying
one percent (1.0%) by a fraction, the numerator of which shall be the number of Registrable Securities for which there is not
an effective Registration Statement at such time and the denominator of which shall be the number of Registrable Securities at
such time.

 

3.
PIGGYBACK REGISTRATION

 

(a)
Whenever the Issuer proposes to register any shares of its Common Stock under the Securities Act (other than a registration effected
solely to implement an employee benefit plan or a transaction to which Rule 145 of the Securities Act is applicable, or a Registration
Statement on Form S-4, S-8 or any successor form thereto or another form not available for registering the Registrable Securities
for sale to the public), whether for its own account or for the account of one or more stockholders of the Issuer and the form
of Registration Statement to be used may be used for any registration of Registrable Securities (a “Piggyback Registration”),
the Issuer shall give prompt written notice (in any event no later than ten (10) Business Days prior to the filing of such Registration
Statement) to the Holders of Registrable Securities of its intention to effect such a registration and, subject to Section 3(b)
and Section 3(c), shall include in such registration all Registrable Securities with respect to which the Issuer has received
written requests for inclusion from the Holders of Registrable Securities within five (5) Business Days after the Issuer’s
notice has been given to each such Holder. Each Holder of Registrable Securities agrees that the fact that such a notice has been
delivered shall constitute confidential information. A Piggyback Registration shall not be considered an Underwritten Offering
for purposes of Section 2 of this Agreement.

 

(b)
If a Piggyback Registration is initiated as a primary underwritten offering on behalf of the Issuer and the managing underwriter
advises the Issuer and the Holders of Registrable Securities (if any Holders of Registrable Securities have elected to include
Registrable Securities in such Piggyback Registration) in writing that in its opinion the number of shares of Common Stock proposed
to be included in such registration, including all Registrable Securities and all other shares of Common Stock proposed to be
included in such underwritten offering, exceeds the number of shares of Common Stock which can be sold in such offering and/or
that the number of shares of Common Stock proposed to be included in any such registration would adversely affect the price per
share of the Common Stock to be sold in such offering, the Issuer shall include in such registration (i) first, the number of
shares of Common Stock that the Issuer proposes to sell; (ii) second, (x) the number of shares of Common Stock that the Holders
of Registrable Securities propose to sell and (y) the number of shares of Common Stock that the Existing Rights Holders propose
to sell (subject to such limitations as set forth in the Existing Registration Rights Agreement), allocated pro rata among all
such Holders and Existing Rights Holders on the basis of the number of Registrable Securities proposed for sale by each such holder
and shares of Common Stock subject to registration rights pursuant to the Existing Registration Rights Agreement that the Existing
Rights Holders propose to sell, or in such manner as they may otherwise agree, and (iii) third, if all of the securities described
in clauses (i) and (ii) are included, the number of shares of Common Stock requested to be included therein by holders of Common
Stock (other than Holders and Existing Rights Holders), allocated among such holders in such manner as they may agree.

 

    	 5

    	 

    

 

(c)
If a Piggyback Registration is initiated as an underwritten offering on behalf of a holder of Common Stock other than Registrable
Securities, and the managing underwriter advises the Issuer in writing that in its opinion the number of shares of Common Stock
proposed to be included in such registration, including all Registrable Securities and all other shares of Common Stock proposed
to be included in such underwritten offering, exceeds the number of shares of Common Stock which can be sold in such offering
and/or that the number of shares of Common Stock proposed to be included in any such registration would adversely affect the price
per share of the Common Stock to be sold in such offering, the Issuer shall include in such registration (i) first, the number
of shares of Common Stock requested to be included therein by the holder(s) requesting such registration, (ii) second, (x) the
number of shares of Common Stock that the Holders of Registrable Securities propose to sell and (y) the number of shares of Common
Stock that the Existing Rights Holders propose to sell (subject to such limitations as set forth in the Existing Registration
Rights Agreement), allocated pro rata among all such holders on the basis of the number of Registrable Securities proposed for
sale by each such Holder and shares of Common Stock subject to registration rights pursuant to the Existing Registration Rights
Agreement that the Existing Rights Holders propose to sell, or in such manner as they may otherwise agree, and (iii) third, if
all of the securities described in clauses (i) and (ii) are included, the number of shares of Common Stock requested to be included
therein by holders of Common Stock (other than Holders of Registrable Securities and Existing Rights Holders), allocated among
such holders in such manner as they may agree.

 

(d)
If any Piggyback Registration is initiated as a primary underwritten offering on behalf of the Issuer, the Issuer shall select
the investment banking firm or firms to act as the managing underwriter or underwriters in connection with such offering.

the date such Holders receive the notice referred to in clause (2) and the date referred to in such notice. The amendment and
prospectus supplement provisions of Section 4(g) shall not be applicable during the period of any Allowable Grace Period.

(b)
If on any day after the effective date of a Registration Statement, sales of all of the Registrable Securities included on such
Registration Statement cannot be made (other than during an Allowable Grace Period) pursuant to such Registration Statement or
otherwise (including, without limitation, because the Registrable Shares are not listed on a Trading Market or because of the
suspension of trading of the Common Stock on the Trading Market on which such Common Stock is then traded, a failure to keep such
Registration Statement effective, a failure to disclose such information as is necessary for sales to be made pursuant to such
Registration Statement or the Registration Statement ceases to be effective for any reason or the Prospectus contained therein
is not available for use for any reason), or the Issuer fails to file with the SEC any required reports under Section 13 or 15(d)
of the Exchange Act such that it is not in compliance with Rule 144(c)(1) (or Rule 144(i)(2), if applicable) as a result of which
any of the Holders of Registrable Securities included in such Registration Statement are unable to sell Registrable Securities
without restriction under Rule 144 (including, without limitation, volume restrictions) then, as partial relief for the damages
to any such Holder by reason of any such delay in or reduction of its ability to sell the underlying shares of Common Stock (which
remedy shall not be exclusive of any other remedies available at law or in equity, including, without limitation, specific performance
or any additional obligation to register Registrable Securities pursuant to this Agreement) (any such event, a “Failure”),
the Issuer shall pay to each holder of Registrable Securities relating to such Registration Statement, a cash amount equal to,
or, at such Holder’s election if offered by the Issuer, warrants to purchase Common Stock of the Issuer with a Black-Scholes
value of no less than, one percent (1.0%) of the market value (based upon the most recent closing price of the Common Stock on
the Trading Market on which such Common Stock has been traded) of such Holder’s Registrable Securities, on the thirtieth
(30th) day after the date of a Failure and every thirtieth (30th) day thereafter (pro-rated for periods totaling less than thirty
(30) days) until such Failure is cured. Notwithstanding anything to the contrary contained herein, (i) such payments shall cease
to accrue when all of the Registrable Securities may be sold pursuant to Rule 144 without any restrictions or limitations, and
(ii) in no event shall the aggregate amount of all such payments paid to a Holder exceed an amount equal to ten percent (10%)
of such Holder’s original purchase price (or conversion price, as applicable) for the Registrable Securities.

 

6.
EXPENSES

 

All
expenses (other than Selling Expenses) incurred by the Issuer in complying with its obligations pursuant to this Agreement and
in connection with the registration and disposition of Registrable Securities, including, without limitation, all registration
and filing fees, underwriting expenses (other than fees, commissions or discounts), expenses of any audits incident to or required
by any such registration, fees and expenses of complying with securities and “blue sky” Laws, printing expenses, fees
and expenses of the Issuer’s counsel and accountants and fees and expenses of one counsel for the Holders of Registrable
Securities participating in such registration as a group (selected by Holders of a majority of the Registrable Securities), shall
be paid by the Issuer. All Selling Expenses relating to Registrable Securities registered pursuant to this Agreement shall be
borne and paid by the Holders of such Registrable Securities, in proportion to the number of Registrable Securities registered
for each such Holder.

 

7.
INDEMNIFICATION

 

In
the event any Registrable Securities are included in a Registration Statement under this Agreement:

 

(a)
To the fullest extent permitted by law, the Issuer will, and hereby does, indemnify, hold harmless and defend each Holder and
each Person that is a transferee in accordance with Section 18, the directors, officers, partners, members, employees, agents,
representatives of, and each Person, if any, who controls any Holder within the meaning of the Securities Act or the Exchange
Act (each, an “Holder Indemnified Person”), against any losses, claims, damages, liabilities, judgments, fines,
penalties, charges, costs, reasonable attorneys’ fees, amounts paid in settlement or expenses, joint or several (collectively,
“Claims”), incurred in investigating, preparing or defending any action, claim, suit, inquiry, proceeding,
investigation or appeal taken from the foregoing by or before any court or governmental, administrative or other regulatory agency,
body or the SEC, whether pending or threatened, whether or not an indemnified party is or may be a party thereto (“Indemnified
Damages”), to which any of them may become subject insofar as such Claims (or actions or proceedings, whether commenced
or threatened, in respect thereof) arise out of or are based upon:

 

(i)
any untrue statement or alleged untrue statement of a material fact in a Registration Statement or any post-effective amendment
thereto or in any filing made in connection with the qualification of the offering under the securities or other “blue sky”
laws of any jurisdiction in which Registrable Securities are offered (“Blue Sky Filing”), or the omission or
alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading;

 

(ii)
any untrue statement or alleged untrue statement of a material fact contained in any preliminary Prospectus if used prior to the
effective date of such Registration Statement, or contained in the final Prospectus (as amended or supplemented, if the Issuer
files any amendment thereof or supplement thereto with the SEC) or the omission or alleged omission to state therein any material
fact necessary to make the statements made therein, in light of the circumstances under which the statements therein were made,
not misleading;

 

    	 9

    	 

    

 

(iii)
any violation or alleged violation by the Issuer of the Securities Act, the Exchange Act, any other law, including, without limitation,
any state securities law or any rule or regulation thereunder relating to the offer or sale of the Registrable Securities pursuant
to a Registration Statement; or

 

(iv)
any violation of this Agreement (the matters in the foregoing clause (i) through and including this clause (iv) being, collectively,
“Violations”).

 

Subject
to Section 7(c), the Issuer shall reimburse the Holder Indemnified Persons, promptly as such expenses are incurred and are due
and payable, for any reasonable legal fees or other expenses incurred by them in connection with investigating or defending any
such Claim. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section
7(a): (1) shall not apply to a Claim by a Holder Indemnified Person arising out of or based upon a Violation which occurs in reliance
upon and in conformity with information furnished in writing to the Issuer by such Holder Indemnified Person for such Holder Indemnified
Person expressly for use in connection with the preparation of the Registration Statement or any such amendment thereof or supplement
thereto, if such Prospectus was timely made available by the Issuer; and (2) shall not apply to amounts paid in settlement of
any Claim if such settlement is effected without the prior written consent of the Issuer, which consent shall not be unreasonably
withheld, conditioned or delayed. Such indemnity shall remain in full force and effect regardless of any investigation made by
or on behalf of the Holder Indemnified Person and shall survive the transfer of any of the Registrable Securities by a Holder
pursuant to Section 18.

 

(b)
In connection with any Registration Statement in which a Holder is participating, each such Holder agrees to severally and not
jointly indemnify, hold harmless and defend, to the same extent and in the same manner as is set forth in Section 7(a), the Issuer,
each of its directors, each of its officers who signs the Registration Statement and each Person, if any, who controls the Issuer
within the meaning of the Securities Act or the Exchange Act (each, an “Issuer Indemnified Party”), against
any Claim or Indemnified Damages to which any of them may become subject, under the Securities Act, the Exchange Act or otherwise,
insofar as such Claim or Indemnified Damages arise out of or are based upon:

 

(i)
any untrue statement of a material fact in a Registration Statement or any post-effective amendment thereto or in any Blue Sky
Filing, or the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements
therein not misleading;

 

(ii)
any untrue statement of a material fact contained in any preliminary Prospectus if used prior to the effective date of such Registration
Statement, or contained in the final Prospectus (as amended or supplemented, if the Issuer files any amendment thereof or supplement
thereto with the SEC) or the omission or alleged omission to state therein any material fact necessary to make the statements
made therein, in light of the circumstances under which the statements therein were made, not misleading;

 

in
each case to the extent, and only to the extent, that the foregoing occurs in expressly permitted reliance upon and in strict
conformity with written information furnished to the Issuer by such Holder expressly for use in connection with such Registration
Statement; and, subject to Section 7(c), such Holder shall reimburse the Issuer Indemnified Party for any legal or other expenses
reasonably incurred by an Issuer Indemnified Party in connection with investigating or defending any such Claim; provided,
however, that the indemnity agreement contained in this Section 7(b) and the agreement with respect to contribution contained
in Section 7(f) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written
consent of such Holder, which consent shall not be unreasonably withheld or delayed; provided, further, however, that the
Holder shall be liable under this Section 7(b) for only that amount of a Claim or Indemnified Damages as does not exceed the net
proceeds to such Holder as a result of the sale of Registrable Securities pursuant to such Registration Statement. Such indemnity
shall remain in full force and effect regardless of any investigation made by or on behalf of such Issuer Indemnified Party and
shall survive the transfer of the Registrable Securities by an Holder pursuant to Section 18.

 

    	 10

    	 

    

 

(c)
Promptly after receipt by a Holder Indemnified Person or Issuer Indemnified Party under this Section 7 of notice of the commencement
of any action or proceeding (including any governmental action or proceeding) involving a Claim, such Holder Indemnified Person
or Issuer Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section
7, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right
to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed,
to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Holder Indemnified
Person or the Issuer Indemnified Party, as the case may be; provided, however, that a Holder Indemnified Person or Issuer
Indemnified Party shall have the right to retain its own counsel with the fees and expenses of not more than one counsel for all
such Holder Indemnified Persons or Issuer Indemnified Party(ies) to be paid by the indemnifying party, if, in the reasonable opinion
of counsel retained by the Holder Indemnified Person or Issuer Indemnified Party, as applicable, the representation by such counsel
of the Holder Indemnified Person or Issuer Indemnified Party and the indemnifying party would be inappropriate due to actual or
potential differing interests between such Holder Indemnified Person or Issuer Indemnified Party and any other party represented
by such counsel in such proceeding. In the case of a Holder Indemnified Person, legal counsel referred to in the immediately preceding
sentence shall be selected by the Holders holding at least a majority in interest of the Registrable Securities included in the
Registration Statement to which the Claim relates. The Issuer Indemnified Party or Holder Indemnified Person shall reasonably
cooperate with the indemnifying party in connection with any negotiation or defense of any such action or Claim by the indemnifying
party and shall furnish to the indemnifying party all information reasonably available to the Issuer Indemnified Party or Holder
Indemnified Person which relates to such action or Claim. The indemnifying party shall keep the Issuer Indemnified Party or Holder
Indemnified Person fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto.
No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its prior written
consent, provided, however, that the indemnifying party shall not unreasonably withhold, delay or condition its consent.
No indemnifying party shall, without the prior written consent of the Issuer Indemnified Party or Holder Indemnified Person, consent
to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof
the giving by the claimant or plaintiff to such Issuer Indemnified Party or Holder Indemnified Person of a release from all liability
in respect to such Claim or litigation and such settlement shall not include any admission as to fault on the part of the Issuer
Indemnified Party. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights
of the Issuer Indemnified Party or Holder Indemnified Person with respect to all third parties, firms or corporations relating
to the matter for which indemnification has been made. The failure to deliver written notice to the indemnifying party within
a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Holder
Indemnified Person or Issuer Indemnified Party under this Section 7, except to the extent that the indemnifying party is prejudiced
in its ability to defend such action.

 

(d)
Where the Issuer is the indemnifying party, the indemnification required by this Section 7 shall be made by periodic payments
of the amount thereof during the course of the investigation or defense, as and when bills are received or Indemnified Damages
are incurred.

 

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

 

(f)
To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make
the maximum contribution with respect to any amounts for which it would otherwise be liable under this Section 7 to the fullest
extent permitted by law; provided, however, that: (i) no Person involved in the sale of Registrable Securities which Person
is guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) in connection with such
sale shall be entitled to contribution from any Person involved in such sale of Registrable Securities who was not guilty of fraudulent
misrepresentation (in each case, as determined by a final non-appealable order of a court of competent jurisdiction); and (ii)
contribution by any seller of Registrable Securities shall be limited in amount to the amount of net proceeds received by such
seller from the sale of such Registrable Securities pursuant to such Registration Statement. Notwithstanding the provisions of
this Section 7(f), no Holder shall be required to contribute, in the aggregate, any amount in excess of the amount by which the
net proceeds actually received by such Holder from the applicable sale of the Registrable Securities subject to the Claim exceed
the amount of any damages that such Holder has otherwise been required to pay, or would otherwise be required to pay under Section
7(b), by reason of such untrue or alleged untrue statement or omission or alleged omission.

8.
PARTICIPATION IN UNDERWRITTEN REGISTRATIONS

 

No
Person may participate in any registration hereunder which is underwritten unless such Person, (a) agrees to sell such Person’s
securities on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve
such arrangements, provided such arrangements are customary for similar offerings, and (b) completes and executes all customary
questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such
underwriting arrangements; provided, that no Holder of Registrable Securities included in any underwritten registration
shall be required to make any representations or warranties to the Issuer or the underwriters (other than representations and
warranties regarding such Holder, such Holder’s ownership of its shares of Common Stock to be sold in the offering and such
Holder’s intended method of distribution) or to undertake any indemnification obligations to the Issuer or the underwriters
with respect thereto, except as otherwise provided in Section 7.

 

9.
RULE 144 COMPLIANCE

 

With
a view to making available to the Holders of Registrable Securities the benefits of Rule 144 and any other rule or regulation
of the SEC that may at any time permit a Holder to sell securities of the Issuer to the public without registration or pursuant
to a registration on Form S-1, Form S-3 or any successor forms thereto, the Issuer shall:

 

(a)
make and keep public information available, as those terms are understood and defined in Rule 144, at all times after the Closing
Date;

 

(b)
use reasonable best efforts to file with the SEC in a timely manner all reports and other documents required of the Issuer under
the Securities Act and the Exchange Act, at any time after the Issuer has become subject to such reporting requirements; and

 

(c)
furnish to any Holder so long as the Holder owns Registrable Securities, promptly upon request, a written statement by the Issuer
as to its compliance with the reporting requirements of Rule 144 and of the Securities Act and the Exchange Act, a copy of the
most recent annual or quarterly report of the Issuer, and such other reports and documents so filed or furnished by the Issuer
as such Holder may reasonably request in connection with the sale of Registrable Securities without registration.

 

10.
PRESERVATION OF RIGHTS

 

The
Issuer shall not (a) grant any registration rights to third parties which are more favorable than or inconsistent with the rights
granted hereunder, or (b) enter into any agreement, take any action, or permit any change to occur, with respect to its securities
that violates or subordinates the rights expressly granted to the Holders of Registrable Securities in this Agreement.

 

11.
TERMINATION

 

This
Agreement shall terminate and be of no further force or effect when no securities of the Issuer constitute Registrable Securities;
provided, that the provisions of Section 6 and Section 7 shall survive any such termination.

 

12.
REMEDIES

 

Each
Holder of Registrable Securities, in addition to being entitled to exercise all rights granted by Law, including recovery of damages,
shall be entitled to specific performance of its rights under this Agreement. The Issuer acknowledges that monetary damages would
not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Agreement and the Issuer
hereby agrees to waive the defense in any action for specific performance that a remedy at Law would be adequate.

as otherwise provided herein, the provisions of this Agreement may only be amended, modified, supplemented or waived with the
prior written consent of the Issuer and the Holders of at least a majority of the Registrable Securities, provided, however, that

Except as otherwise set forth in this Agreement, no failure to exercise, or delay in exercising, any right, remedy, power or privilege
arising from this Agreement shall operate or be construed as a waiver thereof; nor shall any single or partial exercise of any
right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right,
remedy, power or privilege.

AMENDMENT TO

 

AMENDED
AND RESTATED REGISTRATION RIGHTS AGREEMENT OF

 

ECO-STIM
ENERGY SOLUTIONS, INC.

 

This
First Amendment to the Amended and Restated Registration Rights Agreement (this “First Amendment”) of
Eco-Stim Energy Solutions, Inc., a Nevada corporation (the “Company”), is entered into by and between
the Company and the other parties named on the signature pages hereto with reference to that certain Amended and Restated Registration
Rights Agreement, dated July 6, 2017 between the Company and the parties identified therein (the “Amended and Restated
Registration Rights Agreement”), to be effective as of the Closing (as defined in the Subscription Agreement). Capitalized
terms used but not defined herein shall have the meaning ascribed to each such term in the Amended and Restated Registration Rights
Agreement.

 

Recitals

 

	 	A.	In
    connection with a proposed private placement of shares of the Company’s common stock, par value $0.001 per share, and
    the Company’s sale and issuance of shares of its common stock pursuant to a Common Stock Subscription Agreement between
    the Company and the Purchasers identified therein, dated as of August 2, 2017 (the “Subscription Agreement”),
    it has been proposed that the Amended and Restated Registration Rights Agreement be amended as provided herein.
	 	 	 
	 	B.	Pursuant
    to Section 20 of the Amended and Restated Registration Rights Agreement, except with respect to certain circumstances not
    relevant here, the Amended and Restated Registration Rights Agreement may be amended, supplemented, or otherwise modified
    pursuant to an instrument in writing executed by the Company, the Note Purchaser, and Holders of at least seventy-five percent
    (75%) of the Registrable Securities (other than the Note Purchaser) (the “Requisite Stockholders”),
    and such written amendment or modification will be binding upon the Company, each Holder and the Note Purchaser.
	 	 	 
	 	C.	The
    undersigned constitute the Requisite Stockholders.

 

Amendment

 

NOW,
THEREFORE, the Rights Agreement is hereby amended effective as of the Closing as follows:

 

	1.	Section
                                         1(a) is hereby amended to include the following:

 

“PIPE
Registration Rights Agreement” means that certain Registration Rights Agreement between the Issuer and the parties named
thereto, to be effective as of the Closing.

 

“PIPE
Rights Holder” or “PIPE Rights Holders” means stockholders of the Issuer who have registration rights
pursuant to the PIPE Registration Rights Agreement.

 

	2.	Section
                                         2(c) is hereby amended and restated in its entirety to provide as follows:

 

(c)
The Issuer shall not be obligated to effect any Demand Registration within a hundred and twenty (120) days after the effective
date of a previous Demand Registration or a previous Piggyback Registration in which Holders were permitted to register, and actually
sold, all of the shares of Registrable Securities requested to be included therein; provided, however, that such one hundred
and twenty (120) day wait period will not apply to any Demand Registration requested within such time period after the shelf registration
statement required pursuant to Section 2(a) of the PIPE Registration Rights Agreement has been declared effective. The Issuer
may postpone for up to twenty (20) Business Days the filing or effectiveness of a Registration Statement for a Demand Registration
if the Issuer’s Board of Directors determines in its reasonable good faith judgment that such Demand Registration would
(i) materially interfere with a significant acquisition, corporate organization or other similar transaction involving the Issuer;
(ii) require premature disclosure of material information that the Issuer has a bona fide business purpose for preserving as confidential;
or (iii) render the Issuer unable to comply with requirements under the Securities Act or Exchange Act; provided, that
in such event the Holders of a majority of the Registrable Securities initiating such Demand Registration shall be entitled to
withdraw such request and, if such request is withdrawn, such Demand Registration shall not count as one of the permitted Demand
Registrations hereunder and the Issuer shall pay all registration expenses in connection with such registration. The Issuer may
delay a Demand Registration hereunder only twice in any period of twelve (12) consecutive months.

 

    	1

    	 		 

    

 

	3.	Section
                                         2(e) is hereby amended and restated in its entirety to provide as follows:

 

(e)
The Issuer shall not include in any Demand Registration any securities which are not Registrable Securities without the prior
written consent of the Holders of a majority of the Registrable Securities included in such registration, which consent shall
not be unreasonably withheld or delayed. If a Demand Registration involves an underwritten offering and the managing underwriter
of the requested Demand Registration advises the Issuer and the Holders of Registrable Securities to be included in that Demand
Registration in writing that in its opinion the number of shares of Common Stock proposed to be included in the Demand Registration,
including all Registrable Securities and all other shares of Common Stock proposed to be included in such underwritten offering,
exceeds the number of shares of Common Stock which can be sold in such underwritten offering and/or the number of shares of Common
Stock proposed to be included in such registration would adversely affect the price per share of the Registrable Securities proposed
to be sold in such underwritten offering, the Issuer shall include in such Demand Registration (i) first, the number of shares
of Common Stock that the Holders of Registrable Securities who are Demand Holders propose to sell, allocated pro rata among the
respective Holders thereof on the basis of the number of Registrable Securities owned by each such Holder, (ii) second, if all
of the shares requested to be sold under clause (i) are included, (x) the number of shares of Common Stock that the other Holders
of Registrable Securities propose to sell and (y) if PIPE Rights Holders elect to participate in such underwritten offering pursuant
to the PIPE Registration Rights Agreement, the number of shares of Common Stock that such PIPE Rights Holders propose to sell,
pro rata (among clauses (x) and (y)) in accordance with their respective requests and (iii) third, if all of the securities requested
to be sold under clauses (i) and (ii) are included the number of shares of Common Stock proposed to be included therein by any
other Persons (including shares of Common Stock to be sold for the account of the Issuer and/or other holders of Common Stock)
allocated among such Persons in such manner as they may agree. If the managing underwriter determines that less than all of the
Registrable Securities proposed to be sold can be included in such offering, then the Registrable Securities that are included
in such offering shall be allocated among the respective Holders thereof, giving effect to the priorities set forth in the immediately
preceding sentence.

 

	4.	Section
                                         2(f) is hereby amended and restated in its entirety to provide as follows:

 

(f)
Notwithstanding any other provision of this Agreement and subject to the payment of liquidated damages pursuant to Section 2(g),
if the SEC 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 Issuer used reasonable best efforts to
advocate with the SEC 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:

 

	 	(i)	First,
    the Issuer shall reduce or eliminate any securities to be included other than (A) Registrable Securities held by Holders or
    (B) securities of the Issuer held by PIPE Rights Holders subject to registration rights pursuant to the PIPE Registration
    Rights Agreement; and
	 	 	 
	 	(ii)
    	Second,
    if further reduction is required after the elimination of all securities described in Section 2(f)(i), the Issuer shall reduce
    pro rata in accordance with their respective requests the securities of the Issuer held by PIPE Rights Holders subject to
    registration pursuant to the PIPE Registration Rights Agreement; and 
	 	 	 
	 	(iii)	Third,
    if further reduction is required after the elimination of all securities described in Sections 2(f)(i) and (ii), the Registrable
    Securities held by Holders.

 

    	2

    	 		 

    

 

In
the event of a cutback hereunder, the Issuer shall give each Holder at least five (5) Trading Days prior written notice along
with the calculations as to such Holder’s allotment. In the event the Issuer amends the initial Registration Statement in
accordance with the foregoing, the Issuer will use its best efforts to file with the SEC, as promptly as allowed by the SEC or
SEC Guidance provided to the SEC or to registrants of securities in general, one or more registration statements on Form S-1 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.	Section
                                         3(b) is hereby amended and restated in its entirety to provide as follows:

 

(b)
If a Piggyback Registration is initiated as a primary underwritten offering on behalf of the Issuer and the managing underwriter
advises the Issuer and the holders of Registrable Securities (if any holders of Registrable Securities have elected to include
Registrable Securities in such Piggyback Registration) in writing that in its opinion the number of shares of Common Stock proposed
to be included in such registration, including all Registrable Securities and all other shares of Common Stock proposed to be
included in such underwritten offering, exceeds the number of shares of Common Stock which can be sold in such offering and/or
that the number of shares of Common Stock proposed to be included in any such registration would adversely affect the price per
share of the Common Stock to be sold in such offering, the Issuer shall include in such registration (i) first, the number of
shares of Common Stock that the Issuer proposes to sell; (ii) second, (x) the number of shares of Common Stock that the Note Purchaser
and the Holders of Registrable Securities propose to sell and (y) the number of shares of Common Stock that the PIPE Rights Holders
propose to sell (subject to such limitations as set forth in the PIPE Registration Rights Agreement), allocated pro rata among
all such Holders and PIPE Rights Holders on the basis of the number of Registrable Securities proposed for sale by each such Holder
and shares of Common Stock subject to registration rights pursuant to the PIPE Registration Rights Agreement that the PIPE Rights
Holders propose to sell, or in such manner as they may otherwise agree, and (iii) third, if all of the securities described in
clauses (i) and (ii) are included, the number of shares of Common Stock requested to be included therein by holders of Common
Stock (other than Holders of Registrable Securities and PIPE Rights Holders), allocated among such holders in such manner as they
may agree; provided, that in any event and so long as the Note Purchaser is permitted to register all of the Registrable
Securities it desires to be included in such registration, the other Holders of Registrable Securities shall be entitled to register
at least twenty-five percent (25%) of the securities to be included in any such registration.

 

	6.	Section
                                         3(c) is hereby amended and restated in its entirety to provide as follows:

 

(c)
If a Piggyback Registration is initiated as an underwritten offering on behalf of a holder of Common Stock other than Registrable
Securities, and the managing underwriter advises the Issuer in writing that in its opinion the number of shares of Common Stock
proposed to be included in such registration, including all Registrable Securities and all other shares of Common Stock proposed
to be included in such underwritten offering, exceeds the number of shares of Common Stock which can be sold in such offering
and/or that the number of shares of Common Stock proposed to be included in any such registration would adversely affect the price
per share of the Common Stock to be sold in such offering, the Issuer shall include in such registration (i) first, the number
of shares of Common Stock requested to be included therein by the holder(s) requesting such registration, (ii) second, (x) the
number of shares of Common Stock that the Note Purchaser and the other Holders of Registrable Securities propose to sell and (y)
the number of shares of Common Stock that the PIPE Rights Holders propose to sell (subject to such limitations as set forth in
the PIPE Registration Rights Agreement), allocated pro rata among all such holders on the basis of the number of Registrable Securities
proposed for sale by each such Holder and shares of Common Stock subject to registration rights pursuant to the PIPE Registration
Rights Agreement that the PIPE Rights Holders propose to sell, or in such manner as they may otherwise agree, and (iii) third,
if all of the securities described in clauses (i) and (ii) are included, the number of shares of Common Stock requested to be
included therein by holders of Common Stock (other than Holders of Registrable Securities and PIPE Rights Holders), allocated
among such holders in such manner as they may agree.

 

	7.	Except
    as amended by this First Amendment, the Amended and Restated Registration Rights Agreement remains the same and in full force
    and effect.
	 	 
	8.	This
    First Amendment may be executed in two or more counterparts, each of which when so executed and delivered shall be deemed
    an original, but all such counterparts together shall constitute but one and the same instrument. This First Amendment shall
    become effective upon the Closing.
