ARTICLE
II

REGISTRATION RIGHTS


 


Section 2.1          Demand
Registration. Upon the written request (a “Notice”) by the Holder, the Company shall file with the Commission,
as soon as reasonably practicable, but in no event more than 30 days following the receipt of the Notice, a registration statement (each,
a “Registration Statement”) under the Securities Act providing for the resale of the Registrable Securities (which
may, at the option of the Holder, be a registration statement under the Securities Act that provides for the resale of the Registrable
Securities pursuant to Rule 415 from time to time by the Holder (a “Shelf Registration Statement”)). The Company shall
use its commercially reasonable efforts to cause each Registration Statement to be declared effective by the Commission as soon as reasonably
practicable after the initial filing of the Registration Statement. Any Registration Statement shall provide for the resale pursuant
to any method or combination of methods legally available to, and requested by, the Holder. To the extent the initial Registration Statement
is not made on Form S-3, the Company shall, upon becoming eligible to file a registration statement on Form S-3, prepare and file a new
Registration Statement on Form S-3 to replace the initial Registration Statement and use its best efforts to cause such subsequent Registration
Statement to be declared effective by the Commission as soon as reasonably practicable thereafter. The Company shall use its commercially
reasonable efforts to cause each Registration Statement filed pursuant to this Section 2.1 to be continuously effective,
supplemented and amended to the extent necessary to ensure that it is available for the resale of all Registrable Securities by the Holder
until all Registrable Securities covered by such Registration Statement have ceased to be Registrable Securities (the “Effectiveness
Period”). Each Registration Statement when effective (and the documents incorporated therein by reference) shall comply as
to form in all material respects with all applicable requirements of the Securities Act and shall not 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 not misleading.
The Holder shall be limited to two demand registrations under this Section 2.1 in any twelve-month period (provided, however,
that there shall be no limit on the number of Shelf Registration Statements that may be required by the Holder hereunder), and the Company
shall not be obligated to file more than one Registration Statement within 120 days after the effective date of any Registration Statement
filed by the Company; provided, further, that no demand registration under this Section 2.1 shall be deemed to have
occurred for purposes of this sentence if the Registration Statement relating thereto (a) does not become effective within 180 days of
the date first filed with the Commission, (b) is not maintained effective for the Effectiveness Period required under this Section
2.1 or (c) the offering of the Registrable Securities pursuant to such Registration Statement is subject to a stop order, injunction,
or similar order or requirement of the Commission during such period.


 


Section 2.2          Underwritten
Offerings.


 


(a)
Request for Underwritten Offering. Subject to Section 2.2(b), in the event that the Holder elects to dispose of Registrable
Securities pursuant to an Underwritten Offering, the Company shall, upon written request by the Holder, retain underwriters in order
to permit the Holder to effect such sale through an Underwritten Offering. The obligation of the Company to retain underwriters shall
include entering into an underwriting agreement in customary form with the Managing Underwriter(s), which shall include, among other
provisions, indemnities to the effect and to the extent provided in Section 2.8 and taking all reasonable actions as are
requested by the Managing Underwriter(s) to expedite or facilitate the disposition of such Registrable Securities. The Company shall,
upon request of the Holder, cause its management to participate in a roadshow or similar marketing effort on behalf of the Holder.


 


(b)
Limitation on Underwritten Offerings. In no event shall the Company be required under Section 2.2(a) to participate
in more than three Underwritten Offerings requested by the Holder in any twelve-month period.





    3


     


    

(c)
General Procedures. In connection with any Underwritten Offering under this Agreement, the Holder shall be entitled, subject to
the Company’s consent (which is not to be unreasonably withheld, conditioned or delayed), to select the Managing Underwriter(s).
In connection with any Underwritten Offering under this Agreement, the Holder and the Company shall be obligated to enter into an underwriting
agreement that contains such representations and warranties, covenants, indemnities and other rights and obligations as are customary
in underwriting agreements for firm commitment offerings of securities. The Holder may not participate in such Underwritten Offering
unless the Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes
all questionnaires, powers of attorney, indemnities and other documents reasonably required under the terms of such underwriting agreement.
The Holder may, at its option, require that (i) any or all of the representations and warranties by, and the other agreements on the
part of, the Company to and for the benefit of such underwriters also be made to and for the Holder’s benefit and that any or all
of the conditions precedent to the obligations of such underwriters under such underwriting agreement also be conditions precedent to
the Holder’s obligations, and (ii) the Company deliver such documents and certificates as may be reasonably requested by the Holder,
its counsel or the Managing Underwriter(s) to evidence the continued validity of the representations and warranties made by the Company
pursuant to this Section 2.2(c) and to evidence compliance with any customary conditions contained in such underwriting agreement.
If the Holder disapproves of the terms of an underwriting, the Holder may elect to withdraw from the Underwritten Offering by notice
to the Company and the Managing Underwriter(s); provided, however, that such withdrawal must be made at a time prior to the time
of pricing of such Underwritten Offering. No such withdrawal shall affect the Company’s obligation to pay Registration Expenses.


 


Section 2.3          Piggyback
Rights.


 


(a)
Participation. If the Company proposes to file (i) a registration statement or (ii) a prospectus supplement to an effective
shelf registration statement and the Holder may be included in the offering to which such prospectus supplement relates without the filing
of a post-effective amendment to such shelf registration statement, in each case, for the sale of Common Stock in an Underwritten Offering
for its own account and/or another Person, then as soon as practicable following the engagement of counsel by the Company to prepare
the documents to be used in connection with such Underwritten Offering, the Company shall give prompt notice (including notification
by electronic mail) of such proposed Underwritten Offering to the Holder and such notice shall offer the Holder the opportunity to include
in such Underwritten Offering such number of Registrable Securities (the “Included Registrable Securities”) as the
Holder may request in writing. Subject to Section 2.3(b), the Company shall include in such Underwritten Offering all included
Registrable Securities with respect to which the Company has received requests within five (5) Business Days (or one (1) Business
Day in connection with a “bought deal” or an “overnight” Underwritten Offering) after the Company’s notice
has been delivered in accordance with Section 3.1. If no written request for inclusion from the Holder is received within
the specified time, the Holder shall have no further right to participate in such Underwritten Offering. If, at any time after giving
written notice of its intention to undertake an Underwritten Offering and prior to the closing of such Underwritten Offering, the Company
shall determine for any reason not to undertake or to delay such Underwritten Offering, the Company may, at its election, give written
notice of such determination to the Holder and, (x) in the case of a determination not to undertake such Underwritten Offering,
shall be relieved of its obligation to sell any Included Registrable Securities in connection with such terminated Underwritten Offering
and (y) in the case of a determination to delay such Underwritten Offering, shall be permitted to delay offering any Included Registrable
Securities for the same period as the delay in the Underwritten Offering. The Holder shall have the right to withdraw the Holder’s
request for inclusion of the Holder’s Registrable Securities in such Underwritten Offering by giving written notice to the Company
of such withdrawal at or prior to the time of pricing of such Underwritten Offering.


 


(b)
Priority of Registration. If the Managing Underwriter(s) of any proposed Underwritten Offering advises the Company in writing
that in its reasonable view the total amount of Registrable Securities that the Holder and any other Persons intend to include in such
offering exceeds the number that can be sold in such offering without being likely to have an adverse effect in any material respect
on the price, timing or distribution of the Common Stock offered or the market for the Common Stock, then the total number of shares
of Common Stock to be included in such Underwritten Offering shall be reduced to such number of shares of Common Stock that such Managing
Underwriter(s) advises the Company can be sold without having such adverse effect, with such number to be allocated (i) first, to
the Company, unless the Holder initiates the Underwritten Offering, in which case it shall be first allocated to the Holder, and (ii) second,
to the Holder (or to the Company, if the Holder initiates the Underwritten Offering).





    4


     


    

Section 2.4          Delay
Rights. If the Company’s board of directors determines that that the filing of a Registration Statement with respect to Registrable
Securities pursuant to Section 2.1 would be materially detrimental to the Company and its shareholders because such registration
would (a) materially interfere with a significant acquisition, reorganization, financing or other similar transaction involving
the Company, (b) require premature disclosure of material information that the Company has a bona fide business purpose for preserving
as confidential or (c) render the Company unable to comply with applicable securities laws, then the Company shall have the right
to postpone compliance with its obligations under this Article II with respect to such Registration Statement for a period of
not more than three months, provided, that such right pursuant to this Section 2.4 may not be utilized more than twice
in any twelve-month period; and provided, further, that the Company shall at all times use its reasonable best efforts
to cause any Registration Statement required under Section 2.1 to be filed as soon as possible. The Company shall promptly give
the Holder written notice of any postponement made in accordance with this Section 2.4.


 


Section 2.5          Sale
Procedures. In connection with its obligations under this Article II, the Company will, as expeditiously as reasonably practicable:


 


(a)
prepare and file with the Commission such amendments and supplements to each Registration Statement and the prospectus used in connection
therewith as may be necessary to keep each Registration Statement effective for the Effectiveness Period and as may be necessary to comply
with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such Registration
Statement;


 


(b)
if a prospectus supplement will be used in connection with the marketing of an Underwritten Offering and the Managing Underwriter(s)
notifies the Company in writing that, in the sole judgment of such Managing Underwriter(s), inclusion of detailed information in such
prospectus supplement is of material importance to the success of the Underwritten Offering of such Registrable Securities, use its commercially
reasonable efforts to include such information in such prospectus supplement;


 


(c)
furnish to the Holder (i) as far in advance as reasonably practicable before filing a Registration Statement or any supplement or
amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits
and each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission), and
provide the Holder the opportunity to object to any information pertaining to the Holder and its plan of distribution that is contained
therein and make the corrections reasonably requested by the Holder with respect to such information prior to filing a Registration Statement
or supplement or amendment thereto, and (ii) such number of copies of such Registration Statement and the prospectus included therein
and any supplements and amendments thereto as such Persons may reasonably request in order to facilitate the public sale or other disposition
of the Registrable Securities covered by such Registration Statement;


 


(d)
if applicable, use its commercially reasonable efforts to register or qualify the Registrable Securities covered by a Registration Statement
under the securities or blue sky laws of such jurisdictions as the Holder or, in the case of an Underwritten Offering, the Managing Underwriter(s),
shall reasonably request; provided, however, that the Company will not be required to qualify generally to transact business in
any jurisdiction where it is not then required to so qualify or to take any action that would subject it to general service of process
in any jurisdiction where it is not then so subject;


 


(e)
promptly notify the Holder and each underwriter, at any time when a prospectus is required to be delivered under the Securities Act,
of (i) the filing of a Registration Statement or any prospectus or prospectus supplement to be used in connection therewith, or
any amendment or supplement thereto, and, with respect to such Registration Statement or any post-effective amendment thereto, when the
same has become effective; and (ii) any written comments from the Commission with respect to any filing referred to in clause (i) and
any written request by the Commission for amendments or supplements to a Registration Statement or any prospectus or prospectus supplement
thereto;





    5


     


    

(f)
immediately notify the Holder and each underwriter, at any time when a prospectus is required to be delivered under the Securities Act,
of (i) the happening of any event as a result of which the prospectus or prospectus supplement contained in a Registration Statement,
as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein
or necessary in order to make the statements therein not misleading (in the case of the prospectus contained therein, in the light of
the circumstances under which a statement is made); (ii) the issuance or threat of issuance by the Commission of any stop order suspending
the effectiveness of a Registration Statement, or the initiation of any proceedings for that purpose; or (iii) the receipt by the
Company of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable
securities or blue sky laws of any jurisdiction. Following the provision of such notice, the Company agrees to, as promptly as practicable,
amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement
does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in
order to make the statements therein not misleading in the light of the circumstances then existing and to take such other commercially
reasonable action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;


 


(g)
upon request and subject to appropriate confidentiality obligations, furnish to the Holder copies of any and all transmittal letters
or other correspondence with the Commission or any other governmental agency or self-regulatory body or other body having jurisdiction
(including any domestic or foreign securities exchange) relating to any offering of Registrable Securities;


 


(h)
in the case of an Underwritten Offering, furnish upon request, (i) an opinion of counsel for the Company dated the date of the closing
under the underwriting agreement and (ii) a “cold comfort” letter, dated the pricing date of such Underwritten Offering
(to the extent available) and a letter of like kind dated the date of the closing under the underwriting agreement, in each case, signed
by the independent public accountants who have certified the Company’s financial statements included or incorporated by reference
into the applicable registration statement, and each such opinion and “cold comfort” letter shall be in customary form and
covering substantially the same matters with respect to such registration statement (and the prospectus and any prospectus supplement
included therein) as have been customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered
to the underwriters in Underwritten Offerings of securities by the Company or its predecessors and such other matters as such underwriters
and the Holder may reasonably request;


 


(i)
otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make available
to its security holders, as soon as reasonably practicable, an earnings statement, which earnings statement shall satisfy the provisions
of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;


 


(j)
make available to the appropriate representatives of the Managing Underwriter(s) and the Holder access to such information and Company
personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act;

Except
to the extent required by applicable law, the Company shall not file any Registration Statement with respect to any Registrable Securities,
or any prospectus used in connection therewith, and shall not file or make any amendment to any such Registration Statement or any amendment
of or supplement to any such prospectus, that refers to the Holder covered thereby by name, or otherwise identifies the Holder as the
holder of any securities of the Company, without the consent of the Holder, such consent not to be unreasonably withheld, conditioned
or delayed, unless and to the extent such disclosure is required by law or regulation, in which case the Company shall provide written
notice to the Holder no less than two (2) Business Days prior to the filing of such Registration Statement or any amendment to any
such Registration Statement or any prospectus used in connection therewith or any amendment of or supplement to any such Prospectus.





    6


     


    

The
Holder, upon receipt of notice from the Company of the happening of any event of the kind described in subsection (f) of this Section 2.5,
shall forthwith discontinue disposition of the Registrable Securities by means of a prospectus or prospectus supplement until the Holder’s
receipt of the copies of the supplemented or amended prospectus contemplated by subsection (f) of this Section 2.5 or

or supplemental filings incorporated by reference in the prospectus.


 


Section 2.6          Cooperation
by Holder. The Company shall have no obligation to include in a Registration Statement, or in an Underwritten Offering pursuant to

Section 2.8          Indemnification.


 


(a)
By the Company. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement,
the Company will indemnify and hold harmless the Holder, its directors, officers, employees and agents, and each Person, if any, who
controls the Holder within the meaning of the Securities Act and the Securities Exchange Act of 1934, as amended, and the rules and regulations
promulgated thereunder (the “Exchange Act”), and its directors, officers, employees or agents, against any losses,
claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”),
joint or several, to which the Holder, director, officer, employee, agent or controlling Person thereof may become subject under the
Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in
respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact (in the case of
any prospectus or any Written Testing-the-Waters Communication, in the light of the circumstances under which such statement is made)
contained in any Written Testing-the-Waters Communication, a Registration Statement, any preliminary prospectus or prospectus supplement,
free writing prospectus or final prospectus or prospectus supplement contained therein, or any amendment or supplement thereof, or arise
out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary
to make the statements therein (in the case of a prospectus or any Written Testing-the-Waters Communication, in the light of the circumstances
under which they were made) not misleading, and will reimburse the Holder, its directors, officers, employees and agents, and each such
controlling Person, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such
Loss or actions or proceedings as such expenses are incurred; provided, however, that the Company will not be liable in any such
case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission
or alleged omission so made in conformity with information furnished by the Holder, its directors, officers, employees and agents or
such controlling Person in writing specifically for use in any Written Testing-the-Waters Communication, a Registration Statement, any
preliminary prospectus or prospectus supplement, free writing prospectus or final prospectus or prospectus supplement contained therein,
or any amendment or supplement thereto, as applicable. Such indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of the Holder or any such directors, officers, employees agents or controlling Person, and shall survive the transfer
of such securities by the Holder.





    7


     


    

(b)
By the Holder. The Holder agrees to indemnify and hold harmless the Company, its directors, officers, employees and agents and
each Person, if any, who controls the Company within the meaning of the Securities Act or of the Exchange Act, and its directors, officers,
employees and agents, to the same extent as the foregoing indemnity from the Company to the Holder, but only with respect to information
regarding the Holder furnished in writing by or on behalf of the Holder expressly for inclusion in any Written Testing-the-Waters Communication,
a Registration Statement, any preliminary prospectus or prospectus supplement, free writing prospectus or final prospectus or prospectus
supplement contained therein, or any amendment or supplement thereof.


 


(c)
Notice. Promptly after receipt by the indemnified party hereunder of notice of the commencement of any action, the indemnified
party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing
thereof, but the omission to so notify the indemnifying party shall not relieve the indemnifying party from any liability that it may
have to any indemnified party. In any action brought against any indemnified party, the indemnified party shall notify the indemnifying
party of the commencement thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume
and undertake the defense thereof with counsel reasonably satisfactory to the indemnified party and, after notice from the indemnifying
party to the indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable
to the indemnified party under this Section 2.8 for any legal expenses subsequently incurred by the indemnified party in
connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided,
however, that, (i) if the indemnifying party has failed to assume the defense or employ counsel reasonably acceptable to the
indemnified party or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and
counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are
different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may
be deemed to conflict with the interests of the indemnifying party, then the indemnified party shall have the right to select a separate
counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and
fees of such separate counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party
as incurred. Notwithstanding any other provision of this Agreement, no indemnified party shall settle any action brought against it with
respect to which it is entitled to indemnification hereunder without the consent of the indemnifying party, unless the settlement thereof
imposes no liability or obligation on, and includes a complete and unconditional release from all liability of, the indemnifying party.


 


(d)
Contribution. If the indemnification provided for in this Section 2.8 is held by a court or government agency of competent
jurisdiction to be unavailable to the indemnified party or is insufficient to hold them harmless in respect of any Losses, then the indemnifying
party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result
of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the
indemnified party on the other in connection with the statements or omissions that resulted in such Losses, as well as any other relevant
equitable considerations. The relative fault of the indemnifying party on the one hand and the indemnified party on the other shall be
determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties’
relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto
agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation
or by any other method of allocation that does not take account of the equitable considerations referred to herein. The amount paid by
the indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal
and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss that is the subject
of this paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any Person who is not guilty of fraudulent misrepresentation.

Section 2.9          Rule
144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the
sale of the Registrable Securities to the public without registration, the Company agrees to use its commercially reasonable efforts
to:


 


(a)
make and keep public information regarding the Company available, as those terms are understood and defined in Rule 144 under the Securities
Act, at all times from and after the date hereof;


 


(b)
file with the Commission in a timely manner all reports and other documents required of the Company under the Exchange Act at all times
from and after the date hereof; and


 


(c)
so long as the Holder owns any Registrable Securities, unless otherwise available via the Commission’s EDGAR system, furnish to
the Holder forthwith upon request a copy of the most recent annual or quarterly report of the Company, and such other reports and documents
so filed as the Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing the Holder to sell
any such securities without registration.


 


Section 2.10          Transfer
or Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities granted to the Holder by
the Company under this Article II may be transferred or assigned by the Holder to one or more transferee(s) or assignee(s) of
such Registrable Securities; provided, however, that (a) unless such transferee or assignee is an Affiliate of Acuitas, each
such transferee or assignee holds Registrable Securities representing at least five percent (5%) of the then-outstanding Registrable
Securities (subject to adjustment pursuant to Section 3.4), (b) the Company is given written notice prior to any said transfer
or assignment, stating the name and address of each such transferee and identifying the Registrable Securities with respect to which
such registration rights are being transferred or assigned, and (c) each such transferee agrees to be bound by this Agreement.


 


Section 2.11          Restrictions
on Public Sale by the Holder of Registrable Securities. In connection with an Underwritten Offering, if requested by the Managing
Underwriter(s), the Holder agrees to enter into a customary letter agreement with such underwriters providing that the Holder will not
effect any public sale or distribution of the Registrable Securities during the 90 calendar day period beginning on the date of a prospectus
or prospectus supplement filed by the Company with the Commission with respect to the pricing of such Underwritten Offering (the “Holdback
Period”), provided that (i) the duration of the foregoing restrictions shall be no longer than the duration of the shortest
restriction generally imposed by the underwriters on the Company or the officers, directors or any other stockholder of the Company on
whom a restriction is imposed and (ii) the restrictions set forth in this Section 2.11 shall not apply to any Registrable
Securities that are included in such Underwritten Offering by the Holder. If any registration pursuant to Section 2.1 shall be
in connection with any Underwritten Offering, during the Holdback Period, the Company will not effect any public sale or distribution
of any shares of Common Stock (or any securities convertible into or exchangeable or exercisable for shares of Common Stock) (other than
a registration statement (x) on Form S 4, Form S 8 or any successor forms thereto or (y) filed solely in connection with an exchange
offer or any employee benefit or dividend reinvestment plan) for its own account.
