Registration.


 


2.1.1 Request for
Registration. Subject to the provisions of subsection
2.1.4 and Section 2.4
hereof, at any time and from time to time on or after the date the Company consummates the Business Combination, the Holders of
at least fifteen percent (15%) of the then-outstanding number of Registrable Securities (the “Demanding Holders”)
may make a written demand for Registration of all or part of their Registrable Securities, which written demand shall describe
the amount and type of securities to be included in such Registration and the intended method(s) of
distribution thereof (such written demand a “Demand Registration”).
The Company shall, within ten (10) days of the Company’s
receipt of the Demand Registration, notify, in writing, all other Holders of Registrable Securities of such demand, and each Holder
of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s
Registrable Securities in a Registration pursuant to a Demand Registration (each such Holder that includes all or a portion of
such Holder’s Registrable Securities in such Registration,
a “Requesting Holder”)
shall so notify the Company, in writing, within five (5) days
after the receipt by the Holder of the notice from the Company. Upon receipt by the Company of any such written notification from
a Requesting Holder(s) to the Company, such Requesting Holder(s) shall
be entitled to have their Registrable Securities included in a Registration pursuant to a Demand Registration and the Company shall
effect, as soon thereafter as practicable, but not more than forty five (45) days
immediately after the Company’s receipt of the Demand Registration,
the Registration of all Registrable Securities requested by the Demanding Holders and Requesting Holders pursuant to such Demand
Registration. Under no circumstances shall the Company be obligated to effect more than an aggregate of three (3) Registrations
pursuant to a Demand Registration under this subsection
2.1.1 with respect to any or all Registrable Securities; provided, however,
that a Registration shall not be counted for such purposes unless a Form S-1
or any similar long-form registration statement that may be available at such time (“Form S-1”)
has become effective and all of the Registrable Securities requested by the Requesting Holders to be registered on behalf of the
Requesting Holders in such Form S-1 Registration have been
sold, in accordance with Section 3.1 of
this Agreement.


 


2.1.2 Effective Registration.
Notwithstanding the provisions of subsection 2.1.1 above
or any other part of this Agreement, a Registration pursuant to a Demand Registration shall not count as a Registration unless
and until (i) the Registration Statement filed with the Commission
with respect to a Registration pursuant to a Demand Registration has been declared effective by the Commission and (ii) the
Company has complied with all of its obligations under this Agreement with respect thereto; provided, further,
that if, after such Registration Statement has been declared effective, an offering of Registrable Securities in a Registration
pursuant to a Demand Registration is subsequently interfered with by any stop order or injunction of the Commission, federal or
state court or any other governmental agency the Registration Statement with respect to such Registration shall be deemed not to
have been declared effective, unless and until, (i) such stop
order or injunction is removed, rescinded or otherwise terminated, and (ii) a
majority-in-interest of the Demanding Holders initiating such Demand Registration thereafter affirmatively elect to continue with
such Registration and accordingly notify the Company in writing, but in no event later than five (5) days,
of such election; and provided, further,
that the Company shall not be obligated or required to file another Registration Statement until the Registration Statement that
has been previously filed with respect to a Registration pursuant to a Demand Registration becomes effective or is subsequently
terminated. 


 


2.1.3 Underwritten
Offering. Subject to the provisions of subsection 2.1.4 and Section 2.4 hereof,
if a majority-in-interest of the Demanding Holders so advise the Company as part of their Demand Registration that the offering
of the Registrable Securities pursuant to such Demand Registration shall be in the form of an Underwritten Offering, then the right
of such Demanding Holder or Requesting Holder (if any) to include its Registrable Securities in such Registration shall be conditioned
upon such Holder’s participation in such Underwritten Offering
and the inclusion of such Holder’s Registrable Securities
in such Underwritten Offering to the extent provided herein. All such Holders proposing to distribute their Registrable Securities
through an Underwritten Offering under this subsection
2.1.3 shall enter into an underwriting agreement in customary
form with the Underwriter(s) selected for such Underwritten
Offering by the majority-in-interest of the Demanding Holders initiating the Demand Registration.

2.1.4 Reduction of
Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Registration pursuant to a Demand Registration,
in good faith, advises the Company, the Demanding Holders and the Requesting Holders (if any) in writing that the dollar amount
or number of Registrable Securities that the Demanding Holders and the Requesting Holders (if any) desire to sell, taken together
with all other Common Stock or other equity securities that the Company desires to sell and the Common Stock, if any, as to which
a Registration has been requested pursuant to separate written contractual piggy-back registration rights held by any other stockholders
who desire to sell, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten
Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success
of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”),
then the Company shall include in such Underwritten Offering, as follows: (i) first,
the Registrable Securities of the Demanding Holders and the Requesting Holders (if any) (pro rata based on the respective number
of Registrable Securities that each Demanding Holder and Requesting Holder (if any) has requested be included in such Underwritten
Registration and the aggregate number of Registrable Securities that the Demanding Holders and Requesting Holders have requested
be included in such Underwritten Registration (such proportion is referred to herein as “Pro Rata”))
that can be sold without exceeding the Maximum Number of Securities; (ii) second,
to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the Registrable Securities

rights to register their Registrable Securities pursuant to subsection 2.2.1 hereof,
without exceeding the Maximum Number of Securities; and (iii) third,

Number of Securities; and (iv) fourth, to the extent that
the Maximum Number of Securities has not been reached under the foregoing clauses (i), (ii) and

Registration pursuant to separate written contractual arrangements with such persons and that can be sold without exceeding the
Maximum Number of Securities.

or Underwriters (if any) of their intention to withdraw from such Registration prior to the effectiveness of the Registration Statement
filed with the Commission with respect to the Registration of their Registrable Securities pursuant to such Demand Registration.
Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred
in connection with a Registration pursuant to a Demand Registration prior to its withdrawal under this subsection
2.1.5. 


 


2.2 Piggyback
Registration.


 


2.2.1 Piggyback Rights.
If, at any time on or after the date the Company consummates a Business Combination, the Company proposes to file a Registration

or exchangeable for, or convertible into equity securities, for its own account or for the account of stockholders of the Company
(or by the Company and by the stockholders of the Company including, without limitation, pursuant to Section 2.1 hereof),
other than a Registration Statement (i) filed in connection
with any employee stock option or other benefit plan, (ii) for
an exchange offer or offering of securities solely to the Company’s
existing stockholders, (iii) for an offering of debt that
is convertible into equity securities of the Company or (iv) for
a dividend reinvestment plan, then the Company shall give written notice of such proposed filing to all of the Holders of Registrable
Securities as soon as practicable but not less than ten (10) days
before the anticipated filing date of such Registration Statement, which notice shall (A) describe
the amount and type of securities to be included in such offering, the intended method(s) of
distribution, and the name of the proposed managing Underwriter or Underwriters, if any, in such offering, and (B) offer
to all of the Holders of Registrable Securities the opportunity to register the sale of such number of Registrable Securities as
such Holders may request in writing within five (5) days after
receipt of such written notice (such Registration a “Piggyback Registration”).
The Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and shall use
its best efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering to permit the Registrable
Securities requested by the Holders pursuant to this subsection
2.2.1 to be included in a Piggyback Registration on the
same terms and conditions as any similar securities of the Company included in such Registration and to permit the sale or other
disposition of such Registrable Securities in accordance with the intended method(s) of
distribution thereof. All such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under
this subsection 2.2.1 shall
enter into an underwriting agreement in customary form with the Underwriter(s) selected
for such Underwritten Offering by the Company.

and (iii) the Common Stock, if any, as to which Registration
has been requested pursuant to separate written contractual piggy-back registration rights of other stockholders of the Company,

Number of Securities has not been reached under the foregoing clauses (A) and (B), the Common Stock, if any, as to which Registration
has been requested pursuant to written contractual piggy-back registration rights of other stockholders of the Company, which can
be sold without exceeding the Maximum Number of Securities;

no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of his, her or its intention
to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed with the Commission
with respect to such Piggyback Registration. The Company (whether on its own good faith determination or as the result of a request
for withdrawal by persons pursuant to separate written contractual obligations) may withdraw a Registration Statement filed with
the Commission in connection with a Piggyback Registration at any time prior to the effectiveness of such Registration Statement.
Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred
in connection with the Piggyback Registration prior to its withdrawal under this subsection

or any similar short form registration statement that may be available at such time (“Form S-3”); provided, however,

all or such portion of such Holder’s Registrable Securities

2.4 Restrictions
on Registration Rights. If (A) during the period
starting with the date sixty (60) days prior to the Company’s
good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days

Holders prior to receipt of a Demand Registration pursuant to subsection

all reasonable efforts to cause the applicable Registration Statement to become effective; (B) the
Holders have requested an Underwritten Registration and the Company and the Holders are unable to obtain the commitment of underwriters
to firmly underwrite the offer; or (C) in the good faith judgment
of the Board such Registration would be seriously detrimental to the Company and the Board concludes as a result that it is essential
to defer the filing of such Registration Statement at such time, then in each case the Company shall furnish to such Holders a
certificate signed by the Chairman of the Board stating that in the good faith judgment of the Board it would be seriously detrimental

thirty (30) days; provided, however,
that the Company shall not defer its obligation in this manner more than once in any 12-month period.

of Registrable Securities included in such Registration or the legal counsel for any such Holders may request in order to facilitate

    8


     


    

 


3.1.4 prior to any public
offering of Registrable Securities, use its best efforts to (i) register
or qualify the Registrable Securities covered by the Registration Statement under such securities or “blue
sky” laws of such jurisdictions in the United States as the
Holders of Registrable Securities included in such Registration Statement (in light of their intended plan of distribution) may
request and (ii) take such action necessary to cause such
Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental authorities
as may be necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be
necessary or advisable to enable the Holders of Registrable Securities included in such Registration Statement to consummate the
disposition of such Registrable Securities in such jurisdictions; provided, however,
that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be
required to qualify or take any action to which it would be subject to general service of process or taxation in any such jurisdiction
where it is not then otherwise so subject;


 


3.1.5 cause all such
Registrable Securities to be listed on each securities exchange or automated quotation system on which similar securities issued
by the Company are then listed;


 


3.1.6 provide a transfer
agent or warrant agent, as applicable, and registrar for all such Registrable Securities no later than the effective date of such
Registration Statement;


 


3.1.7 advise each seller
of such Registrable Securities, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop
order by the Commission suspending the effectiveness of such Registration Statement or the initiation or threatening of any proceeding
for such purpose and promptly use its reasonable best efforts to prevent the issuance of any stop order or to obtain its withdrawal
if such stop order should be issued;


 


3.1.8 at least five (5) days
prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to such Registration Statement or
Prospectus or any document that is to be incorporated by reference into such Registration Statement or Prospectus, furnish a copy
thereof to each seller of such Registrable Securities and its counsel, including, without limitation, providing copies promptly
upon receipt of any comment letters received with respect to any such Registration Statement or Prospectus; 


 


3.1.9 notify the Holders
at any time when a Prospectus relating to such Registration Statement is required to be delivered under the Securities Act, of
the happening of any event as a result of which the Prospectus included in such Registration Statement, as then in effect, includes
a Misstatement, and then to correct such Misstatement as set forth in Section
3.4 hereof;


 


3.1.10 permit a representative
of the Holders (such representative to be selected by a majority of the participating Holders), the Underwriters, if any, and any
attorney or accountant retained by such Holders or Underwriter to participate, at each such person’s
own expense, in the preparation of the Registration Statement, and cause the Company’s
officers, directors and employees to supply all information reasonably requested by any such representative, Underwriter, attorney
or accountant in connection with the Registration; provided, however,
that such representatives or Underwriters enter into a confidentiality agreement, in form and substance reasonably satisfactory
to the Company, prior to the release or disclosure of any such information; and provided further, the Company may not include
the name of any Holder or Underwriter or any information regarding any Holder or Underwriter in any Registration Statement or Prospectus,
any amendment or supplement to such Registration Statement or Prospectus, any document that is to be incorporated by reference
into such Registration Statement or Prospectus, or any response to any comment letter, without the prior written consent of such
Holder or Underwriter and providing each such Holder or Underwriter a reasonable amount of time to review and comment on such applicable
document, which comments the Company shall include unless contrary to applicable law;


 


3.1.11 obtain a “cold
comfort” letter from the Company’s
independent registered public accountants in the event of an Underwritten Registration which the participating Holders may rely
on, in customary form and covering such matters of the type customarily covered by “cold
comfort” letters as the managing Underwriter may reasonably
request, and reasonably satisfactory to a majority-in-interest of the participating Holders;


 






    9


     


    

 


3.1.12 on the date the
Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion, dated such date, of counsel representing
the Company for the purposes of such Registration, addressed to the Holders, the placement agent or sales agent, if any, and the
Underwriters, if any, covering such legal matters with respect to the Registration in respect of which such opinion is being given
as the Holders, placement agent, sales agent, or Underwriter may reasonably request and as are customarily included in such opinions
and negative assurance letters, and reasonably satisfactory to a majority in interest of the participating Holders;


 


3.1.13 in the event of
any Underwritten Offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form,
with the managing Underwriter of such offering;


 


3.1.14 make available
to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve (12) months
beginning with the first day of the Company’s first full
calendar quarter after the effective date of the Registration Statement which satisfies the provisions of Section 11(a) of
the Securities Act and Rule 158 thereunder (or any successor
rule promulgated thereafter by the Commission);


 


3.1.15 if the Registration
involves the Registration of Registrable Securities involving gross proceeds in excess of $25,000,000, use its reasonable efforts
to make available senior executives of the Company to participate in customary “road
show” presentations that may be reasonably requested by the
Underwriter in any Underwritten Offering; and


 


3.1.16 otherwise, in
good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Holders, in connection
with such Registration.


 


3.2 Registration
Expenses. The Registration Expenses of all Registrations shall be borne by the Company. It is acknowledged by the Holders
that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’
commissions and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the definition of “Registration
Expenses,” all reasonable fees and expenses of any legal
counsel representing the Holders.


 


3.3 Requirements
for Participation in Underwritten Offerings. No person may participate in any Underwritten Offering for equity securities
of the Company pursuant to a Registration initiated by the Company hereunder unless such person (i) agrees
to sell such person’s securities on the basis provided in
any underwriting arrangements approved by the Company and (ii) completes
and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting agreements and other
customary documents as may be reasonably required under the terms of such underwriting arrangements. 


 


3.4 Suspension
of Sales; Adverse Disclosure. Upon receipt of written notice from the Company that a Registration Statement or Prospectus
contains a Misstatement, each of the Holders shall forthwith discontinue disposition of Registrable Securities until he, she or
it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that the Company
hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until
he, she or it is advised in writing by the Company that the use of the Prospectus may be resumed. If the filing, initial effectiveness
or continued use of a Registration Statement in respect of any Registration at any time would require the Company to make an Adverse
Disclosure or would require the inclusion in such Registration Statement of financial statements that are unavailable to the Company
for reasons beyond the Company’s control, the Company may,
upon giving prompt written notice of such action to the Holders, delay the filing or initial effectiveness of, or suspend use of,
such Registration Statement for the shortest period of time, but in no event more than thirty (30) days,
determined in good faith by the Company to be necessary for such purpose. In the event the Company exercises its rights under the
preceding sentence, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of
the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities. The Company shall
immediately notify the Holders of the expiration of any period during which it exercised its rights under this Section 3.4.


 






    10


     


    

 


3.5 Reporting
Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting
company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable
grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections
13(a) or 15(d) of
the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings. The Company further covenants
that it shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable
such Holder to sell shares of Common Stock held by such Holder without registration under the Securities Act within the limitation
of the exemptions provided by Rule 144 promulgated under the
Securities Act (or any successor rule promulgated thereafter
by the Commission), including providing any legal opinions. Upon the request of any Holder, the Company shall deliver to such Holder
a written certification of a duly authorized officer as to whether it has complied with such requirements.


 


3.6 Limitations on
Registration Rights. Notwithstanding anything herein to the contrary, the Sponsor, the Forward Purchaser and any transferee
that is an underwriter and related party (as defined in FINRA Rule 5110 and 5121) in connection with the initial public offering
of B. Riley Principal Merger Corp. II (i) may not exercise its rights under Section 2.1 and 2.2 hereunder after five (5) and seven
(7) years, respectively, after the effective date of the registration statement relating to the Company’s initial public
offering and (ii) may not exercise its rights under Section 2.1 more than one time.

INDEMNIFICATION AND CONTRIBUTION


 


4.1 Indemnification.


 


4.1.1 The Company agrees
to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers and directors and each person
who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses
(including attorneys’ fees) caused by any untrue or alleged
untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment
thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished
in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the Underwriters, their officers
and directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided
in the foregoing with respect to the indemnification of the Holder.


 


4.1.2 In connection with
any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to the Company
in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration
Statement or Prospectus and, to the extent permitted by law, shall indemnify the Company, its directors and officers and agents
and each person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities
and expenses (including without limitation reasonable attorneys’
fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus
or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to
make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information
or affidavit so furnished in writing by such Holder expressly for use therein; provided, however,
that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the
liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such
Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall
indemnify the Underwriters, their officers, directors and each person who controls such Underwriters (within the meaning of the
Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company. 


 


4.1.3 Any person entitled
to indemnification herein shall (i) give prompt written notice
to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt
notice shall not impair any person’s right to indemnification
hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless
in such indemnified party’s reasonable judgment a conflict
of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party
to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed,
the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent
(but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the
defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel (plus local counsel) for all parties
indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a
conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim.
No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any
settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party
pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.


 






    11


     


    

 


4.1.4 The indemnification
provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of
the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the transfer of
securities. The Company and each Holder of Registrable Securities participating in an offering also agrees to make such provisions
as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s
or such Holder’s indemnification is unavailable for any reason.


 


4.1.5 If the indemnification
provided under Section 4.1 hereof
from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims,
damages, liabilities and expenses referred to herein, 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 losses, claims, damages, liabilities
and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party,
as well as any other relevant equitable considerations. The relative fault of the 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 to state a material fact, was made by, or relates to information supplied by,
such indemnifying party or indemnified party, and the indemnifying party’s
and indemnified party’s relative intent, knowledge, access
to information and opportunity to correct or prevent such action; provided, however,
that the liability of any Holder under this subsection
4.1.5 shall be limited to the amount of the net proceeds
received by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the
losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in subsections
4.1.1, 4.1.2 and 4.1.3 above,
any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding.
The parties hereto agree that it would not be just and equitable if contribution pursuant to this subsection
4.1.5 were determined by pro rata allocation or by any
other method of allocation, which does not take account of the equitable considerations referred to in this subsection
4.1.5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution pursuant to this subsection
4.1.5 from any person who was not guilty of such fraudulent
misrepresentation.

of the Founder Shares Lock-up Period or the Private Placement Lock-up Period, as the case may be, no Holder may assign or delegate
such Holder’s rights, duties or obligations under this Agreement,
in whole or in part, except in connection with a transfer of Registrable Securities by such Holder to a Permitted Transferee but
only if such Permitted Transferee agrees to become bound by the transfer restrictions set forth in this Agreement.

permitted assigns of the Holders, which shall include Permitted Transferees.

reasonably satisfactory to the Company, to be bound by the terms and provisions of this Agreement (which may be accomplished by
an addendum or certificate of joinder to this Agreement). Any transfer or assignment made other than as provided in this Section 5.2 shall
be null and void.


 


5.3 Counterparts.

Registrable Securities at the time in question, compliance with any of the provisions, covenants and conditions set forth in this
Agreement may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however,
that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects one Holder, solely in his, her
or its capacity as a holder of the shares of capital stock of the Company, in a manner that is materially different from the other
Holders (in such capacity) shall require the consent of the Holder so affected. No course of dealing between any Holder or the
Company and any other party hereto or any failure or delay on the part of a Holder or the Company in exercising any rights or remedies
under this Agreement shall operate as a waiver of any rights or remedies of any Holder or the Company. No single or partial exercise
of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights
or remedies hereunder or thereunder by such party.


 


5.6 Other

has any right to require the Company to register any securities of the Company for sale or to include such securities of the Company
in any Registration filed by the Company for the sale of securities for its own account or for the account of any other person.
Further, the Company represents and warrants that this Agreement supersedes any other registration rights agreement or agreement

Holders of all Registrable Securities are permitted to sell the Registrable Securities without registration pursuant to Rule 144
(or any similar provision) under the Securities Act with no volume or other restrictions or limitations. The provisions of Section 3.5 and
Article IV shall survive any termination.
