REGISTRATIONS

 

2.1 Demand 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 ten percent (10%) in interest 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 three (3) Business 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) Business 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; 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 Ordinary Shares or other equity securities that the Company
desires to sell and the Ordinary Shares, if any, as to which a Registration has been requested pursuant to separate written contractual
piggy-back registration rights held by any other shareholders 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) holds prior to such Underwritten
Registration) 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), Ordinary Shares or other equity securities for the account of other
persons or entities that the Company is obligated to register pursuant to separate written contractual arrangements with such persons
or entities and that 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 (i) and (ii), Ordinary Shares or other equity securities that
the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities.

2.1.5 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 subsection 2.1.1 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,
(i) the Company may effect any Underwritten Registration pursuant to any then effective Registration Statement, including a Form
S-3, that is then available for such offering and (ii) 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 Statement under the Securities Act with respect
to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities,
for its own account or for the account of shareholders of the Company (or by the Company and by the shareholders of the Company including,
without limitation, pursuant to Section 2.1 hereof), other than a Registration Statement (i) filed in connection
with any employee share option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s
existing shareholders, (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) Business 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) Business 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.

 

2.2.2 Reduction of Piggyback Registration. If the managing Underwriter
or Underwriters in an Underwritten Registration that is to be a Piggyback Registration, in good faith, advises the Company and the Holders
of Registrable Securities participating in the Piggyback Registration in writing that the dollar amount or number of Ordinary Shares that
the Company desires to sell, taken together with (i) the Ordinary Shares, 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, (ii) the
Registrable Securities as to which registration has been requested pursuant to Section 2.2 hereof, and (iii) the
Ordinary Shares, if any, as to which Registration has been requested pursuant to separate written contractual piggy-back registration
rights of other shareholders 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 (A) first, Ordinary Shares or other equity securities that the Company desires
to sell, which can be sold without exceeding the Maximum Number of Securities; and (B) second, to the extent that the Maximum Number
of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register
their Registrable Securities pursuant to subsection 2.2.1 hereof and Ordinary Shares, if any, as to which Registration has
been requested pursuant to written contractual piggy-back registration rights of other shareholders of the Company (pro rata based on
the respective number of Registrable Securities that each shareholder holds prior to such Underwritten Registration), which can be sold
without exceeding the Maximum Number of Securities;

 

    6 

     

    

 

(b) If the Registration is pursuant to a request by persons or entities
other than the Holders of Registrable Securities, then the Company shall include in any such Registration (A) first, Ordinary Shares
or other equity securities, if any, of such requesting persons or entities, other than the Holders of Registrable Securities, which can
be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not
been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable
Securities pursuant to subsection 2.2.1 and Ordinary Shares or other equity securities for the account of other persons or
entities that the Company is obligated to register pursuant to separate written contractual arrangements with such persons or entities
(pro rata based on the respective number of Registrable Securities that each shareholder holds prior to such Underwritten Registration),
which can be sold without exceeding the Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of Securities
has not been reached under the foregoing clauses (A) and (B), Ordinary Shares or other equity securities that the Company desires
to sell, which can be sold without exceeding the Maximum Number of Securities.

 

2.2.3 Piggyback Registration 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 (or in the case
of an Underwritten Registration pursuant to Rule 415 under the Securities Act, at least two business days prior to the time of pricing
of the applicable offering). 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 Registration Rights. For purposes
of clarity, any Registration effected pursuant to Section 2.2 hereof shall not be counted as a Registration pursuant
to a Demand Registration effected under Section 2.1 hereof.

 

2.3 Registrations on Form S-3. The Holders of Registrable
Securities may at any time, and from time to time, request in writing that the Company, pursuant to Rule 415 under the Securities
Act (or any successor rule promulgated thereafter by the Commission), register the resale 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 three (3) Business
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 file a Registration Statement relating to 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 securities (if any) at any aggregate price to the public of less than $5,000,001.

 

Any request for an underwritten offering pursuant to a Form S-3 shall
follow the procedures of Section 2.1 (including Section 2.1.4) but shall not count against the number of long form Demand Registrations
that may be made pursuant to Section 2.1.1.

 

    7 

     

    

  

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 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 subsection 2.1.1 and it continues to actively employ, in good faith, 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 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. Notwithstanding anything to the contrary contained in this Agreement, no Registration
shall be effected or permitted and no Registration Statement shall become effective, with respect to any Registrable Securities held
by any Holder, until after the expiration of the Founder Shares Lock-Up Period or the Private Placement Lock-Up Period, as the case
may be.

of process or taxation in any such jurisdiction where it is not then otherwise so subject;

 

    8 

     

    

 

 

 

3.1.5 cause all such Registrable Securities to be listed on each securities

3.1.6 provide a transfer agent or warrant agent, as applicable,

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 or its
counsel;

 

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;

 

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

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

 

    9

     

    

 

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, including, without limitation,
making available senior executives of the Company to participate in any due diligence sessions that may be reasonably requested by the
Underwriter in any Underwritten Offering.

 

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.

 

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 Ordinary Shares 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 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.

 

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.

PRIVATE PLACEMENT WARRANTS PURCHASE AGREEMENT

 

THIS PRIVATE PLACEMENT WARRANTS PURCHASE AGREEMENT, dated as of            , 2021
(as it may from time to time be amended, this “Agreement”), is entered into by and between Sieger Healthcare Acquisition
Corp, a Cayman Islands exempted company (the “Company”), and Sieger Healthcare LLC, a Cayman Island limited liability
company (the “Purchaser”).

 

WHEREAS, the Company intends to consummate an initial public offering
of the Company’s units (the “Public Offering”), each unit consisting of one Class A ordinary share, of par
value $0.0001 per share, of the Company (a “Share”), and one-third of one redeemable warrant, each whole warrant exercisable
for one Share at an exercise price of $11.50 per Share, as set forth in the Company’s registration statement on Form S-1 related
to the Public Offering (the “Registration Statement”); and

 

WHEREAS, the Purchaser has agreed to purchase from the Company an aggregate
of 2,833,333 warrants (or up to 2,983,333 warrants depending on the extent to which the underwriters’ over-allotment option in connection
with the Public Offering is exercised) (the “Sponsor Warrants”), each Sponsor Warrant entitling the holder to purchase
one Share at an exercise price of $11.50 per Share.

 

NOW THEREFORE, in consideration of the mutual promises contained in
this Agreement and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to
this Agreement hereby, intending legally to be bound, agree as follows:

under this Agreement, Purchaser shall pay $4,250,000 (the “Purchase Price”), by wire transfer of immediately available
funds in accordance with the Company’s wiring instructions, at least one (1) business day prior to the initial closing of the
Public Offering, or at such earlier date as the Company and the Purchaser may agree.

 

(ii) In the event that the underwriters’ over-allotment option
is exercised in full or in part, Purchaser shall purchase up to an additional 150,000 Sponsor Warrants (the “Additional Sponsor
Warrants”), in the same proportion as the amount of the over-allotment option that is exercised, simultaneously with such purchase
of Additional Sponsor Warrants. As payment in full for the Additional Sponsor Warrants then being purchased hereunder, at least one (1) business
day prior to the applicable closing of all or any portion of the over-allotment option, or on such earlier date as the Company and the
Purchaser may agree, the Purchaser shall pay $1.50 per Additional Sponsor Warrant, up to an aggregate amount of $225,000, by wire transfer

considered in a proceeding in equity or law).

 

(ii) The execution and delivery by the Purchaser of this Agreement
and the fulfillment of and compliance with the terms hereof by the Purchaser does not and shall not as of the Closing Dates conflict with
or result in a breach by the Purchaser of the terms, conditions or provisions of any agreement, instrument, order, judgment or decree
