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

 

    5 

    	 

    

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 ‎Section 2.01(a) 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 3.01 of this
Agreement.

 

(b)       Effective
Registration. Notwithstanding the provisions of ‎Section 2.01(a) above or any other part of this Agreement, a Registration
pursuant to a Demand Registration shall not count as a Registration unless and until (1) 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 (2) 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.

 

    6 

    	 

    

(c)       Underwritten
Offering. Subject to the provisions of ‎Section 2.01(d) and ‎Section 2.04 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 ‎Section 2.01(c) 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.

 

(d)       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:
(3) 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; (4) 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 ‎Section 2.02(a) hereof, without exceeding the Maximum Number of Securities; and (5) 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 (6) 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

(e)       Demand
Registration Withdrawal. A majority-in-interest of the Demanding Holders initiating a Demand Registration or a majority-in-interest
of the Requesting Holders (if any), pursuant to a Registration under ‎Section 2.01(a) shall have the right to withdraw from
a Registration pursuant to such Demand Registration for any or no reason whatsoever upon written notification to the Company and
the Underwriter 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 ‎Section 2.01(e).

 

Section 2.02.Piggyback
Registration.

 

(a)       Piggyback

exercisable 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
2.01 hereof), other than a Registration Statement (7) filed in connection with any employee stock option or other benefit plan,
(8) for an exchange offer or offering of securities solely to the Company’s existing stockholders, (9) for an offering of
debt that is convertible into equity securities of the Company or (10) 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 ‎Section 2.02(a) 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 ‎Section 2.02(a) shall enter into an underwriting agreement in customary

dollar amount or number of the shares of Common Stock that the Company desires to sell, taken together with (11) the shares of
Common Stock, if any, as to which Registration has been demanded pursuant to separate written contractual arrangements with persons
or entities other than the Holders of Registrable Securities hereunder (12) the Registrable Securities as to which registration
has been requested pursuant to ‎Section 2.02 hereof, and (13) the shares of 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,
exceeds the Maximum Number of Securities, then:

 

(A)       If
the Registration is undertaken for the Company’s account, the Company shall include in any such Registration (i) first,

clause ‎(1), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant
to ‎Section 2.02(a) hereof (pro rata based on the respective number of Registrable Securities that such Holder has requested
be included in such Registration), which can be sold 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 ‎(1) and ‎(2), 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;

or entities, other than the Holders of Registrable Securities, which can be sold without exceeding the Maximum Number of Securities;
(v) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause ‎(1), the
Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to ‎Section 2.02(a),
pro rata based on the number of Registrable Securities that each Holder has requested be included in such Registration and the
aggregate number of Registrable Securities that the Holders have requested to be included in such Registration, which can be sold
without exceeding the Maximum Number of Securities; (vi) third, to the extent that the Maximum Number of Securities has not been
reached under the foregoing clauses ‎(1) and ‎(2), 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 (vii) fourth, to the extent that the Maximum

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 ‎Section 2.02(c).

 

(d)       Unlimited

of any or all of their Registrable Securities on Form S-3 or any similar short form registration statement that may be available
at such time (“Form S-3”); provided, however, that the Company shall not be obligated to effect such request
through an Underwritten 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

faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of,
a Company initiated Registration and provided that the Company has delivered written notice to the Holders prior to receipt of
a Demand Registration pursuant to ‎Section 2.01(a) and it continues to actively employ, in good faith, all reasonable efforts
to cause the applicable Registration Statement to become effective; iii) 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 iv) 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.

of the Registrable Securities owned by such Holders;

 

(d)       prior
to any public offering of Registrable Securities, use its best efforts to (1) 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 (2) 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;

 

(e)       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;

 

(f)       provide
a transfer agent and registrar for all such Registrable Securities no later than the effective date of such Registration Statement;

 

(g)       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;

 

(h)       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 upon receipt of any comment letters received with respect to any such Registration Statement or Prospectus;

 

    12 

    	 

    

(i)       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 3.04 hereof;

 

(j)       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;

 

(k)       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;

 

(l)       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;

 

(m)       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;

 

(n)       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

 

    13 

    	 

    

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);

 

(o)       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

 

(p)       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.

 

Section 3.02.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.

 

Section 3.03.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 (3) agrees to sell such person’s
securities on the basis provided in any underwriting arrangements approved by the Company and (4) 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.

 

Section 3.04.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

 

    14 

    	 

    

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 3.04.

 

Section 3.05.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.

Indemnification and Contribution

 

Section 4.01.Indemnification.

 

(a)       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.

 

(b)       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

 

    15 

    	 

    

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.

 

(c)       Any
person entitled to indemnification herein shall (5) 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 (6) 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.

 

(d)       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.

 

(e)       If
the indemnification provided under ‎Section 4.01 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

 

    16 

    	 

    

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 ‎Section 4.01(e) 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 Sections ‎4.01(a), ‎4.01(b) and ‎4.01(c) 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 ‎Section 4.01(e) 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 ‎Section 4.01(e). 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
‎Section 4.01(e) from any person who was not guilty of such fraudulent misrepresentation.

RE:Private Placement Purchase Agreement

 

Ladies and Gentlemen:

 

Jiya Acquisition Corp., a Delaware corporation
(the “Company”, “we” or “us”), is pleased to accept the offer made by
Jiya Holding Company, LLC, a Delaware limited liability company (“Subscriber” or “you”),
to purchase 500,000 shares (the “Shares”) of Class A common stock of the Company, $0.0001 par value per share
(“Class A Common Stock”), at a price of $10.00 per share concurrently with the Company’s initial public
offering (“IPO”). The terms of the sale by the Company of the Shares to Subscriber, and the Company and Subscriber’s
agreements regarding the Shares, are as follows:

 

1.       
Purchase of Securities.

 

1.1.       Purchase
of Shares. For the sum of $5,000,000 (the “Purchase Price”), which the Company acknowledges receiving in
cash, the Company hereby issues the Shares to Subscriber, and Subscriber hereby purchases the Shares from the Company, on the terms
and subject to the conditions, including regarding forfeiture, set forth in this letter agreement (this “Agreement”).
Concurrently with Subscriber’s execution of this Agreement, the Company shall, at its option, deliver to Subscriber a certificate
registered in Subscriber’s name representing the shares (the “Original Certificate”) or effect such delivery
in book-entry form.

 

2.       Representations,
Warranties and Agreements.

 

2.1.       Subscriber’s
Representations, Warranties and Agreements. To induce the Company to issue the Shares to Subscriber, Subscriber hereby represents
and warrants to the Company and agrees with the Company as follows:

 

2.1.1       Organization
and Authority. Subscriber is a limited liability company, duly organized, validly existing and in good standing under the laws
of State of Delaware, and possesses all requisite power and authority necessary to carry out the transactions contemplated by this
Agreement. This Agreement is a legal, valid and binding agreement of Subscriber, enforceable against Subscriber in accordance with
its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar
laws affecting the enforcement of creditors’ rights generally and subject to general principles of equity (regardless of
whether enforcement is sought in a proceeding at law or in equity).

 

2.1.2       No
Conflicts. The execution, delivery and performance of this Agreement and the consummation by Subscriber of the transactions
contemplated hereby do not violate, conflict with or constitute a default under (i) the formation and governing documents of Subscriber,
(ii) any agreement, indenture or instrument to which Subscriber is a party or (iii) any law, statute, rule, regulation, order,
judgment or decree to which Subscriber is subject.

 

2.1.3       No
Governmental Consents. No governmental, administrative or other third party consents or approvals are required, necessary or
appropriate on the part of Subscriber in connection with the transactions contemplated by this Agreement.

 

2.1.4       Experience,
Financial Capability and Suitability. Subscriber is sophisticated in financial matters and is able to evaluate the risks and
benefits of the investment in the Shares. Subscriber acknowledges that the Shares have not been registered under the Securities
Act of 1933, as amended (the “Securities Act”), and therefore cannot be sold unless subsequently registered under the
Securities Act or an exemption from such registration is available. Subscriber understands that it must bear the economic risk
of this investment until the

 

    	 

    	 

    

Shares are sold pursuant to: (i)
an effective registration statement under the Securities Act or (ii) an exemption from registration available with respect to such
sale. Subscriber is able to bear the economic risk of an investment in the Shares for an indefinite period of time and to afford
a complete loss of Subscriber’s investment in the Shares.

 

2.1.5       No
Government Recommendation or Approval. Subscriber understands that no federal or state agency has passed upon or made any recommendation
or endorsement of the offering of the Shares.

 

2.1.6       Access
to Information; Independent Investigation. Prior to the execution of this Agreement, Subscriber has had the opportunity to
ask questions of and receive answers from representatives of the Company concerning an investment in the Company, as well as the
financial condition, business and prospects of the Company, and the opportunity to obtain additional information to verify the
accuracy of all information so obtained. In determining whether to make this investment, Subscriber has relied solely on Subscriber’s
own knowledge and understanding of the Company and its business based upon Subscriber’s own due diligence investigation.
Subscriber understands that no person has been authorized to make any representations other than as set forth in this Agreement
and Subscriber has not relied on any other written or oral representations relating to the financial condition, business and prospects
of the Company in making its investment decision.

 

2.1.7       Investment
Representations. Subscriber represents that it is an “accredited investor” as such term is defined in Rule 501(a)
of Regulation D under the Securities Act and acknowledges the sale contemplated hereby is being made in reliance on the private
placement exemption in Section 4(a)(2) of the Securities Act and/or said Regulation D and similar exemptions under state law. Subscriber
is purchasing the Shares solely for investment purposes, for Subscriber’s own account and not for the account or benefit
of any other person, and not with a view towards the distribution or dissemination thereof. Subscriber did not decide to enter
into this Agreement as a result of any general solicitation or general advertising within the meaning of Rule 502 under the Securities
Act.

 

2.1.8       Restrictions
on Transfer; Shell Company. Subscriber understands the Shares are being offered in a transaction not involving a public offering
within the meaning of the Securities Act. Subscriber understands the Shares will be “restricted securities” within
the meaning of Rule 144(a)(3) under the Securities Act, and Subscriber understands that the certificates or book-entries representing
the Shares will contain a legend or notation in respect of such restrictions. If, in the future, Subscriber decides to offer, resell,
pledge or otherwise transfer the Shares, such Shares may be offered, resold, pledged or otherwise transferred only pursuant to:
(i) an effective registration statement under the Securities Act or (ii) an exemption from registration available with respect
to such sale. Subscriber agrees that if any transfer of its Shares or any interest therein is proposed to be made, as a condition
precedent to any such transfer, Subscriber may be required to deliver to the Company an opinion of counsel satisfactory to the
Company. Absent registration or available exemption, Subscriber agrees not to resell the Shares. Subscriber further acknowledges
that because the Company is a shell company, Rule 144 may not be available to Subscriber for the resale of the Shares until one
year following consummation of the initial business combination of the Company, despite the release or waiver of any contractual
transfer restrictions.

 

2.2       Company’s
Representations, Warranties and Agreements. To induce Subscriber to purchase the Shares, the Company hereby represents and
warrants to Subscriber and agrees with Subscriber as follows:

 

2.2.1       Organization
and Authority. The Company is a corporation, duly organized, validly existing and in good standing under the laws of the State
of Delaware, and possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement.
This Agreement is a legal, valid and binding agreement of the Company, enforceable against the Company in accordance with its terms,
except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar laws affecting
the enforcement of creditors’ rights generally and subject to general principles of equity (regardless of whether enforcement
is sought in a proceeding at law or in equity).

 

2.2.2       No
Conflicts. The execution, delivery and performance of this Agreement and the consummation by the Company of the transactions
contemplated hereby do not violate, conflict with or constitute a default under (i) the formation and governing documents of the
Company, (ii) any agreement, indenture or instrument to which the Company is a party or (iii) any law, statute, rule, regulation,
order, judgment or decree to which the Company is subject.

 

    2 

    	 

    

2.2.3       No
Governmental Consents. No governmental, administrative or other third party consents or approvals are required, necessary or
appropriate on the part of the Company in connection with the transactions contemplated by this Agreement.

 

2.2.4       Title
to Securities. Upon issuance in accordance with, and payment pursuant to, the terms hereof, the Shares will be duly and validly
issued, fully paid and nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms hereof, Subscriber will
have or receive good title to the Shares, free and clear of all liens, claims and encumbrances of any kind, other than (a) transfer
restrictions hereunder and other agreements to which the Shares may become subject, (b) transfer restrictions under federal and
state securities laws, and (c) liens, claims or encumbrances imposed due to the actions of Subscriber.

 

3.       [Reserved].

 

4.       Waiver
of Redemption Rights. Subscriber may redeem the Shares for a portion of the amounts held in the trust account into which substantially
all of the proceeds of the IPO will be deposited (the “Trust Account”) in the event of the Company’s failure
to timely complete an initial business combination, but, for the avoidance of doubt, not in connection with an extension of the
time period to complete an initial business combination or upon the consummation of an initial business combination.

 

5.       Restrictions
on Transfer.

 

5.1.       Securities
Law Restrictions. In addition to any restrictions to be contained in that certain letter agreement (commonly known as an “Insider
Letter”) to be dated as of the closing of the IPO by and between Subscriber and the Company (which will also contain other
agreements with respect to the Shares), Subscriber agrees not to sell, transfer, pledge, hypothecate or otherwise dispose of all
or any part of the Shares unless, prior thereto, (a) a registration statement on the appropriate form under the Securities Act
and applicable state securities laws with respect to the Shares proposed to be transferred shall then be effective or (b) the Company
has received an opinion from counsel, reasonably satisfactory to the Company, that registration is not required because such transaction
is exempt from registration under the Securities Act and the rules promulgated by the Securities and Exchange Commission thereunder
and all applicable state securities laws.

 

5.2.       Restrictive
Legends. Any certificates representing the Shares shall have endorsed thereon legends substantially as follows (and any book-entries
representing the Shares shall have similar notations):

 

“THE SECURITIES REPRESENTED HEREBY HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND NEITHER THE SECURITIES NOR ANY INTEREST
THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
STATEMENT UNDER SUCH ACT OR SUCH LAWS OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT AND SUCH LAWS WHICH, IN THE OPINION OF COUNSEL,
IS AVAILABLE.”

 

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE
ARE SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER SET FORTH IN A LETTER AGREEMENT WITH THE COMPANY (A COPY OF WHICH MAY BE OBTAINED
FROM THE COMPANY AT THE COMPANY’S PRINCIPAL PLACE OF BUSINESS WITHOUT CHARGE) AND MAY NOT BE OFFERED, SOLD, TRANSFERRED,
PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF IN VIOLATION OF SUCH RESTRICTIONS.”

 

5.3.       Additional
Shares or Substituted Securities. In the event of the declaration of a share dividend, the declaration of an extraordinary
dividend payable in a form other than Shares, a spin-off, a share split, an adjustment in conversion ratio, a recapitalization
or a similar transaction affecting the Company’s outstanding Shares without receipt of consideration, any new, substituted
or additional securities or other property which are by reason of such transaction distributed with respect to any Shares subject
to this Section 5 or into which such Shares thereby become convertible shall immediately be subject to this Section 5 and Section
3 hereof. Appropriate adjustments to reflect the distribution of such securities or property shall be made to the number and/or
class of Shares subject to this Section 5 and Section 3.

 

6.       Other
Agreements.

 

    3 

    	 

    

6.1.       Further
Assurances. Subscriber agrees to execute such further instruments and to take such further action as may reasonably be necessary
to carry out the intent of this Agreement.

 

6.2.       Notices.
All notices, statements or other documents which are required or contemplated by this Agreement shall be in writing and delivered
(i) personally or by certified mail (return receipt requested) or overnight courier service or (ii) by electronic mail, if to the
Company, at the address of its principal offices and any electronic mail address as may be designated in writing by the Company
and, if to Subscriber, at its address in the books and records of the Company and any electronic mail address as may be designated
in writing by Subscriber, or to such other addresses as may be designated in writing by the Company or Subscriber. All such notices,
statements or other documents shall be deemed received on the date of receipt by the recipient thereof if received prior to 8:00
p.m. on a business day in the place of receipt. Otherwise, any such notices, statements or other documents shall be deemed to have
been received on the next succeeding business day in the place of receipt.

 

6.3.       Entire
Agreement. This Agreement, together with the Insider Letter and the registration rights agreement to be entered into with respect
to the Shares, each substantially in the form to be filed as an exhibit to the Registration Statement on Form S-1 associated with
the Company’s IPO, embodies the entire agreement and understanding between Subscriber and the Company with respect to the
subject matter hereof and supersedes all prior oral or written agreements and understandings relating to the subject matter hereof.
No statement, representation, warranty, covenant or agreement of any kind not expressly set forth in this Agreement shall affect,
or be used to interpret, change or restrict, the express terms and provisions of this Agreement.

 

6.4.       Modifications
and Amendments. The terms and provisions of this Agreement may be modified or amended only by written agreement executed by
all parties hereto.

 

6.5.       Waivers
and Consents. The terms and provisions of this Agreement may be waived, or consent for the departure therefrom granted, only
by a written document executed by the party entitled to the benefits of such terms or provisions. No such waiver or consent shall
be deemed to be or shall constitute a waiver or consent with respect to any other terms or provisions of this Agreement, whether
or not similar. Each such waiver or consent shall be effective only in the specific instance and for the purpose for which it was
given, and shall not constitute a continuing waiver or consent.

 

6.6.       Assignment.
The rights and obligations under this Agreement may not be assigned by either party hereto without the prior written consent of
the other party.

 

6.7.       Benefit.
All statements, representations, warranties, covenants and agreements in this Agreement shall be binding on the parties hereto
and shall inure to the benefit of the respective successors and permitted assigns of each party hereto. Nothing in this Agreement
shall be construed to create any rights or obligations except among the parties hereto, and no person or entity shall be regarded
as a third-party beneficiary of this Agreement.

 

6.8.       Governing
Law. This Agreement and the rights and obligations of the parties hereunder shall be construed in accordance with and governed
by the laws of the State of Delaware applicable to contracts wholly performed within the borders of such state, without giving
effect to the conflict of law principles thereof.

 

6.9.       Severability.
In the event that any court of competent jurisdiction shall determine that any provision, or any portion thereof, contained in
this Agreement shall be unreasonable or unenforceable in any respect, then such provision shall be deemed limited to the extent
that such court deems it reasonable and enforceable, and, as so limited, shall remain in full force and effect. In the event that
such court shall deem any such provision, or portion thereof, wholly unenforceable, the remaining provisions of this Agreement
shall nevertheless remain in full force and effect.

 

6.10.       No
Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in exercising any right, power or remedy under
this Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy
of such party. No single or partial exercise of any right, power or remedy under this Agreement by a party hereto, nor any abandonment
or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise
thereof or the exercise of any other right, power or remedy hereunder. The election of any remedy by a party hereto shall not constitute
a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required
under this Agreement shall entitle the party receiving such notice or demand to any other or further notice or

 

    4 

    	 

    

demand in similar or other circumstances or
constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances
without such notice or demand.

 

6.11.       Survival
of Representations and Warranties. All representations and warranties made by the parties hereto in this Agreement or in any
other agreement, certificate or instrument provided for or contemplated hereby, shall survive the execution and delivery hereof
and any investigations made by or on behalf of the parties.

 

6.12.       No
Broker or Finder. Each of the parties hereto represents and warrants to the other that no broker, finder or other financial
consultant has acted on its behalf in connection with this Agreement or the transactions contemplated hereby in such a way as to
create any liability on the other. Each of the parties hereto agrees to indemnify and save the other harmless from any claim or
demand for commission or other compensation by any broker, finder, financial consultant or similar agent claiming to have been
employed by or on behalf of such party and to bear the cost of legal expenses incurred in defending against any such claim.

 

6.13.       Headings
and Captions. The headings and captions of the various subdivisions of this Agreement are for convenience of reference only
and shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof.

 

6.14.       Counterparts.
This Agreement may be executed in one or more counterparts, all of which when taken together shall be considered one and the same
agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being
understood that both parties need not sign the same counterpart. In the event that any signature is delivered in pdf format via
electronic mail, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature
is executed) with the same force and effect as if such signature page were an original thereof.

 

6.15.       Construction.
The parties hereto have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of
intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption
or burden of proof will arise favoring or disfavoring any party hereto because of the authorship of any provision of this Agreement.
The words “include,” “includes,” and “including” will be deemed to be
followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include
any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise
requires. The words “this Agreement,” “herein,” “hereof,” “hereby,”
“hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision
unless expressly so limited. The parties hereto intend that each representation, warranty, and covenant contained herein will have
independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect,
the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the
relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such party
hereto is in breach of the first representation, warranty, or covenant.

 

6.16.       Mutual
Drafting. This Agreement is the joint product of Subscriber and the Company and each provision hereof has been subject to the
mutual consultation, negotiation and agreement of such parties and shall not be construed for or against any party hereto.
