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.


 




    4


     


    

 


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 of Holders (Pro Rata, based on the
respective number of Registrable Securities that each Holder has so requested) exercising their rights to register their Registrable Securities
pursuant to subsection 2.2.1 hereof, without exceeding the Maximum Number of Securities; and (iii) third, to the extent that the
Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), the Common Stock or other equity securities
that the Company desires to sell, which can be sold without exceeding the Maximum 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 (iii), the Common Stock or other
equity securities of other persons or entities that the Company is obligated to register in a Registration pursuant to separate written
contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Securities.

(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

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”).

efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering to permit the Registrable Securities requested

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

Withdrawal. Any Holder of Registrable Securities shall have the right to withdraw from a Piggyback Registration for any or 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 2.2.3.


 


2.2.4 Unlimited Piggyback

Offering. Within five (5) days of the Company’s receipt of a written request from a Holder or Holders of Registrable Securities
for a Registration on Form S-3, the Company shall promptly give written notice of the proposed Registration on Form S-3 to all other Holders
of Registrable Securities, and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s
Registrable Securities in such Registration on Form S-3 shall so notify the Company, in writing, within ten (10) days after the receipt
by the Holder of the notice from the Company. As soon as practicable thereafter, but not more than twelve (12) days after the Company’s
initial receipt of such written request for a Registration on Form S-3, the Company shall register all or such portion of such Holder’s
Registrable Securities as are specified in such written request, together with all or such portion of Registrable Securities of any other
Holder or Holders joining in such request as are specified in the written notification given by such Holder or Holders; provided,
however, that the Company shall not be obligated to effect any such Registration pursuant to Section 2.3 hereof if (i) a
Form S-3 is not available for such offering; or (ii) the Holders of Registrable Securities, together with the Holders of any other equity
securities of the Company entitled to inclusion in such Registration, propose to sell the Registrable Securities and such other equity

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 to the Company for such Registration Statement to be filed in
the near future and that it is therefore essential to defer the filing of such Registration Statement. In such event, the Company shall
have the right to defer such filing for a period of not more than thirty (30) days; provided, however, that the Company
shall not defer its obligation in this manner more than once in any 12-month period.

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, furnish
a copy thereof to each seller of such Registrable Securities and its counsel, including, without limitation, providing copies promptly

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;


 


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);


 




    9


     


    

 


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 such Holder 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 such Holder 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.


 


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.

ARTICLE IV


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.


 


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.


 




    11


     


    

 


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.

Holder’s rights, duties or obligations under this Agreement, in whole or in part, except in connection with a transfer of Registrable

hereto or waiver hereof that adversely affects one Holder, solely in such Holder’s 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 Registration

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

(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.
