of $240,000, or $10.00 per Additional Unit. Each Right entitles the holder thereof to receive one-tenth (1/10) of one Class A ordinary

Option”) in the Offering is exercised in full or part. The total number of Additional Units to be purchased hereunder shall

1.3. Delivery of the Purchase Price.
At least one business day prior to the effective date of the Company’s registration statement relating to the IPO (“Registration

 “Trust Account”). If the IPO is not consummated within 14 days of the date the Initial Purchase Price is delivered
to CST, the Initial Purchase Price shall be returned to the Purchaser by certified bank check or wire transfer of immediately available
funds denominated in United States Dollars, without interest or deduction.

Agreement”) to be entered into with the Company on or prior to the closing of the IPO.

(as defined in the Insider Letter).

form under the Securities Act and applicable state securities laws with respect to the Securities proposed to be transferred shall then

Commission thereunder and with all applicable state securities laws.

 

7. Waiver of Distributions
from Trust Account

 

In connection with the Securities purchased pursuant
to this Agreement, the Purchaser hereby waives any and all right, title, interest or claim of any kind in or to any distributions from
the Trust Account.

 

8. Rescission Right Waiver and Indemnification

 

8.1. Rescission Waiver. The Purchaser
understands and acknowledges that an exemption from the registration requirements of the Securities Act requires there be no general solicitation
of purchasers of the Units. In this regard, if the Offering were deemed to be a general solicitation with respect to the Units, the offer
and sale of such Units may not be exempt from registration and, if not, the Purchaser may have a right to rescind its purchase of the
Units. In order to facilitate the completion of the Offering and in order to protect the Company, its shareholders and the Trust Account
from claims that may adversely affect the Company or the interests of its shareholders, the Purchaser hereby agrees to waive, to the maximum
extent permitted by applicable law, any claims, right to sue or rights in law or arbitration, as the case may be, to seek rescission of
its purchase of the Units as a result of the issuance of the Units being deemed to be in violation of Section 5 of the Securities
Act. The Purchaser acknowledges and agrees this waiver is being made in order to induce the Company to sell the Units to the Purchaser.
The Purchaser agrees the foregoing waiver of rescission rights shall apply to any and all known or unknown actions, causes of action,
suits, claims or proceedings (collectively, “Claims”) and related losses, costs, penalties, fees, liabilities
and damages, whether compensatory, consequential or exemplary, and expenses in connection therewith, including reasonable attorneys’
and expert witness fees and disbursements and all other expenses reasonably incurred in investigating, preparing or defending against
any Claims, whether pending or threatened, in connection with any present or future actual or asserted right to rescind the purchase of
the Units hereunder or relating to the purchase of the Units and the transactions contemplated hereby.

 

    

     

    

 

8.2. No Recourse Against Trust Account.
The Purchaser agrees not to seek recourse against the Trust Account for any reason whatsoever in connection with its purchase of the Units
or any Claim that may arise now or in the future.

 

8.3. Section 8 Waiver. The Purchaser
agrees that to the extent any waiver of rights under this Section 8 is ineffective as a matter of law, the Purchaser has offered
such waiver for the benefit of the Company as an equitable right that shall survive any statutory disqualification or bar that applies
to a legal right. The Purchaser acknowledges the receipt and sufficiency of consideration received from the Company hereunder in this
regard.

 

9. Terms of the Unit

 

The Units shall be substantially identical to
the Units offered in the IPO as set forth in the Underwriting Agreement, except the Units: (i) will be subject to the transfer restrictions
described herein, and (ii) are being purchased pursuant to an exemption from the registration requirements of the Securities Act
and will become freely tradable only after certain conditions are met or the resale of the Units is registered under the Securities Act.

 

10. Governing Law; Jurisdiction; Waiver
of Jury Trial

in accordance with the laws of the State of New York for agreements made and to be wholly performed within such territory. The parties
hereto hereby waive any right to a jury trial in connection with any litigation pursuant to this Agreement and the transactions contemplated
hereby.

nor any rights hereunder may be assigned by any party to any other person other than by the Purchaser, without the prior consent of the
Company, to one or more persons agreeing to be bound by the terms hereof. Upon such assignment by a Purchaser, the assignee(s) shall
become Purchaser hereunder and have the rights and obligations provided for herein to the extent of such assignment.

 

11.2. Entire Agreement. This
Agreement sets forth the entire agreement and understanding between the parties as to the subject matter hereof and supersedes any and
all prior discussions, agreements and understandings of any and every nature.

 

11.3. Amendment. Except as expressly
provided in this Agreement, neither this Agreement nor any term hereof may be amended, waived, discharged or terminated other than by
a written instrument signed by the party against whom enforcement of any such amendment, waiver, discharge or termination is sought.

 

11.4. Binding upon Successors. This
Agreement shall be binding upon and inure to the benefit of the parties hereto and to their respective heirs, legal representatives, successors
and permitted assigns.

 

12. Notices; Indemnity

 

12.1 Notices. All notices, requests,
consents and other communications hereunder shall be in writing, shall be addressed to the receiving party’s address set forth herein
or to such other address as a party may designate by notice hereunder, and shall be either (a) delivered by hand, (b) sent by
overnight courier, or (c) sent by certified mail, return receipt requested, postage prepaid. All notices, requests, consents and
other communications hereunder shall be deemed to have been given either (i) if by hand, at the time of the delivery thereof to the

fees and expenses) incurred as a result of such party’s breach of any representation, warranty, covenant or agreement set forth
in this Agreement.

 

13. 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 by facsimile transmission or any other form of electronic delivery, 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.

 

14. Survival; Severability

 

14.1. Survival. The representations,
warranties, covenants and agreements of the parties hereto shall survive the Closing until one (1) year following the consummation
of an initial Business Combination.

 

14.2. Severability. In the event that
any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this
Agreement shall continue in full force and effect without said provision; provided that no such severability shall be
effective if it materially changes the economic benefit of this Agreement to any party.

 

15. Headings

 

The titles and subtitles used in this Agreement
are used for convenience only and are not to be considered in construing or interpreting this Agreement.

 

16. 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.

based upon the actual number of days in such month and shall be paid on the first day of the month following the month in which the Commencement Date occurs. 

The Base Rent shall be paid in advance, without notice, in equal monthly installments, on or before the first (1st) day of each calendar month occurring during the Term; provided, however, Subtenant shall pay the first (1st) monthly installment of Base Rent concurrent with Subtenant’s execution of this

rate”) or (b) the maximum rate permitted by applicable law. Subtenant shall be entitled to a one-time waiver of the foregoing late charge and interest the first time Subtenant is late in payment

(f) Sublandlord’s failure to deliver any statements or bills required to be delivered to Subtenant hereunder, or Sublandlord’s

accruing during the Term shall survive the expiration or sooner termination of this Sublease. 
 6. Expenses, Taxes and Other Additional

provided that if such amounts are in respect of additional services provided by the Prime Landlord, Subtenant shall only pay such amounts to the extent such additional services are requested by Subtenant. Such payments shall be paid within ten

obligations under the Prime Lease shall, for all purposes of this Sublease be deemed to be the performance of such obligations by Sublandlord, and Sublandlord’s obligations under the Sublease shall be fully discharged to the extent to which
such obligations are performed by the Prime Landlord under the Prime Lease. Notwithstanding the foregoing, Sublandlord shall use reasonable efforts (excluding litigation) to obtain performance by the Prime Landlord of its obligations under the Prime
Lease, with the reasonable cost of such efforts to be borne solely by Subtenant to the extent such performance relates to the Subleased Premises and to be shared on a proportionate share basis by Sublandlord and Subtenant if such performance also

of Prime Landlord in any situation where such consent is required hereunder or under the Prime Lease, Sublandlord shall promptly request such consent from Prime Landlord. In making any such request, Sublandlord shall be acting solely as agent for

(a) Subject to the terms and conditions of this Sublease, Subtenant shall, at its sole cost and expense, perform all alterations, decorations,
additions or otherwise required in order for Subtenant to utilize the Subleased Premises for the purpose of conducting its business therein. Except as otherwise expressly provided in the Prime Lease as to alterations by the Tenant therein permitted
without the Prime Landlord’s consent, Subtenant shall not be permitted to make any alterations, modifications, or improvements to the Subleased Premises without obtaining the prior written consent of Sublandlord and Prime Landlord and without

12. Assignment and Subletting. Subtenant shall not assign this Sublease, nor sublet the Subleased Premises or any part thereof
nor permit any other person or entity to occupy all or any portion of the Subleased Premises without obtaining in each instance, the prior written consent of Sublandlord and, if required under the Prime Lease, the prior written consent of Prime
Landlord. Sublandlord shall not unreasonably withhold or delay such consent. The provisions of Article 11 of the Prime Lease are hereby incorporated herein in the manner set forth in Article 9 of this Sublease. Subtenant shall not have any right to
hypothecate, mortgage or otherwise encumber this Sublease.

 13. Insurance. From and after the Delivery Date, Subtenant shall maintain insurance
in accordance with the provisions of Article 13 of the Prime Lease solely as it applies to the Subleased Premises, except that Prime Landlord and Sublandlord shall be named as additional insureds on such policies. Subtenant shall deliver to
Sublandlord the certificate(s) evidencing such insurance on or before the Commencement Date and thereafter in accordance with the terms of the Prime Lease. Each of Subtenant and Sublandlord hereby waives and release all claims against the other
party for damage or loss to its property which would be covered by a Special Form policy of insurance covering such property, whether or not such insurance is in place and collectible. 

14. Default. (a) Sublandlord reserves the right to terminate this Sublease and Subtenant’s occupancy of the Subleased Premises
on ten (10) business days written notice to Subtenant in the event that (i) Subtenant fails to make any monthly Base Rent or Additional Rent payment within five (5) business days after delivery of written notice to Subtenant of such
failure, or (ii) Subtenant fails to observe and perform any of its obligations under this Sublease within fifteen (15) days after written notice thereof from Sublandlord, except to the extent such default cannot be cured within said
fifteen (15) day period, in which event Subtenant shall have such additional time as may be necessary to cure such default so long as Subtenant has commenced cure within such fifteen (15) day period and is diligently pursuing the remedies
necessary to cure such default. The acceptance of any late payments of Base Rent or Additional Rent shall not be deemed a waiver of Sublandlord’s rights under this section. 

(b) Notwithstanding any other provision herein, Subtenant shall perform all of its obligations hereunder at such times, by such dates or within
such periods as Sublandlord shall be required to perform its corresponding obligations under the Sublease. If Prime Landlord shall give any notice of failure or default under the Sublease or the Prime Lease, as applicable, arising out of any failure
by Subtenant to perform any of its obligations hereunder (other than payment of money), then Sublandlord shall promptly furnish Subtenant with a copy thereof. If the Sublease or Prime Lease shall provide any grace or cure period for such failure or
default then the grace or cure period hereunder shall expire two (2) business days prior to the date on which the grace or cure period under the Prime Lease shall expire. In no event shall this subsection (b) extend the time, date or
period by or within which Subtenant is required to perform. 
 15. Security Deposit. (a) Concurrent with Subtenant’s
execution and delivery of this Sublease to Sublandlord, Subtenant shall pay to Sublandlord by bank check or wire transfer of immediately available federal funds the sum of $197,370 (the “Security Deposit”) to be held by the
Sublandlord as security for the Subtenant’s performance of all the Subtenant’s obligations under this Sublease. Sublandlord shall retain the Security Deposit in a non-interest-bearing account.
Sublandlord shall in no event be obligated to apply the Security Deposit to Rental in arrears or damages for Subtenant’s default, although Sublandlord may so apply the Security Deposit, at its option. The Security Deposit, if not applied toward
the payment of Rental in arrears or toward the payment of damages suffered by Sublandlord by reason of Subtenant’s default, shall be returned to Subtenant without interest when this Sublease is terminated or as otherwise provided in this
Sublease once Subtenant has vacated the Subleased Premises and delivered possession thereof to Sublandlord in accordance with the terms and provisions hereof. If Sublandlord legally repossesses the Subleased Premises because of Subtenant’s
default, Sublandlord may apply the Security Deposit to damages suffered to the date of such repossession and may apply the Security Deposit to such damages as may be suffered or shall accrue thereafter by reason of Subtenant’s default. If
Sublandlord applies the Security Deposit in whole or in part, Subtenant shall, upon demand by Sublandlord, deposit sufficient funds to maintain the Security Deposit in an amount equal to $197,370. Failure of Subtenant to deposit such additional
security shall entitle Sublandlord to avail itself of the remedies provided in this Sublease for nonpayment of Base Rent and Additional Rent by Subtenant. Provided that no Default by Subtenant then exists (after notice and a reasonable opportunity
to cure), on the third anniversary of the Commencement Date, the Security Deposit shall be reduced to $131,580 for the remainder of the Term. 

  
 7 

 (b) At Subtenant’s election, in lieu of the cash Security Deposit required herein,
Subtenant may deliver to Sublandlord a clean, unconditional irrevocable stand-by letter of credit drawn on a Massachusetts clearinghouse bank in a sum equal to the Security Deposit required hereunder, in the
form attached hereto and made a part hereof as Exhibit C (the “Letter of Credit”). Sublandlord shall have the right to draw down the Letter of Credit in accordance with the provisions of this Section 15(b) and
Section 15(d) hereof. The Letter of Credit and any proceeds thereof drawn down by Sublandlord (the “Security”) shall be held by Sublandlord as security for the payment of all Rental which shall or may become payable for the
Term and for the faithful performance by Subtenant of all of the other covenants and agreements made on its part in this Sublease, but Sublandlord shall in no event be obligated to apply the Security to Rental in arrears or damages for
Subtenant’s default, although Sublandlord may so apply the Security, at its option. Sublandlord shall have the absolute right to draw on the Letter of Credit in full immediately upon the occurrence of either of the following: (a) Subtenant
shall fail to renew or replace the Letter of Credit in accordance with this Article; or (b) Subtenant shall be in default under this Sublease after the expiration of the applicable notice or cure period (a “Default”). If
Sublandlord exercises its right to draw down the Letter of Credit and apply the proceeds thereof to satisfy any Subtenant obligation or Default, Subtenant shall, within five (5) business days of the date of Sublandlord’s draw down, replace
the Letter of Credit with a new letter of credit complying with the provisions of this Section 15(b), so that the amount of the Security held by Sublandlord shall always be the sum herein set forth or such lesser sum provided by this Lease.

 (c) Subtenant shall renew or replace the Letter of Credit at least thirty (30) days prior to its expiration date with a renewal or
replacement Letter of Credit complying with the terms of this Article and having an expiration date no earlier than one year from its issuance, and will thereafter renew or replace such renewal or replacement Letter of Credit and each succeeding
Letter of Credit thirty (30) days prior to its expiration, so that a Letter of Credit complying with the terms of this Sublease shall continuously remain in effect until the date occurring sixty (60) days after the expiration of the Term.

 (d) In addition to its obligations to do so under Section 15(b) and Section 15(c), Subtenant shall replace the Letter of Credit
within five (5) business days of receipt of written notice from Sublandlord that the issuer has (i) entered into a supervisory agreement or consent order with the Federal Deposit Insurance Corporation, the Office of Thrift Supervision, or
any other state or federal regulatory authority with jurisdiction such issuer; or (ii) become subject to an order or directive of any of the foregoing authorities with respect to the regulation of its activities; or (iii) notified
Sublandlord that it shall not (A) honor a draw under the Letter of Credit; or (B) renew or extend the Letter of Credit beyond its then current expiration date. 

16. Subordination. This Sublease is subject and subordinate to the Prime Lease and all matters to which this Sublease and the Prime
Lease are subordinate, and to any mortgage(s) which may now or hereafter affect such leases or the Building and/or the land on which the Building is located and all renewals, modifications, consolidations, replacements and extensions thereof. This
subordination shall be self-operative; however, in confirmation thereof, Subtenant shall execute promptly any commercially reasonable instrument that Sublandlord, Prime Landlord or any mortgagee may request confirming such subordination; provided
that no such instrument shall materially increase Subtenant’s obligation sunder this Sublease or materially decrease any rights of Subtenant under this Sublease.  

17. Termination and Amendment of Prime Lease. Sublandlord shall not voluntarily terminate the Prime Lease except pursuant to a right of
termination arising out of casualty or condemnation expressly set forth in the Prime Lease, and Sublandlord shall not amend the Prime Lease in a manner adverse to Subtenant in any material respect. If the Prime Lease shall terminate for any reason,
then this Sublease shall also terminate. Sublandlord shall not be liable for any such termination unless such termination (a) shall have arisen out of a default under the Sublease by Sublandlord not arising out of a default hereunder by
Subtenant or (b) shall have been effected by Sublandlord in violation of this Section.

Subtenant has obtained the prior consent of Prime Landlord. The number of names that Subtenant shall have the right to install on the directory shall be equal to Subtenant’s Proportionate Share of the number of names Sublandlord is entitled to
install on the directory. Upon the expiration or earlier termination of this Sublease, Subtenant shall remove its identification sign and shall repair any damage caused by said installation and/or removal. 

19. Surrender. Upon the expiration or earlier termination of the Term, Subtenant shall vacate, and cause its agents, contractors,

loss, cost, damage, claim and expense (including reasonable legal fees and disbursements) which the indemnified party may sustain or which may be asserted against the indemnified party by reason of a breach of the foregoing representation by the
indemnifying party. Sublandlord shall pay any fee or commission due Newmark pursuant to a separate agreement, and Newmark will pay to Colliers its agreed upon share of such commission. 

23. Consent. The validity of this Sublease is conditioned upon Sublandlord obtaining the written consent of the Prime Landlord (the
