Acquisition Limited
2023 Employee Stock Purchase Plan



Adopted
by the Board of Directors:June 6, 2023
Approved by the Shareholders: June 12, 2023



1.             General;
Purpose.



(a)           The
Plan provides a means by which Eligible Employees of the Company and certain Designated Companies may be given an opportunity to purchase
Shares. The Plan permits the Company to grant a series of Purchase Rights to Eligible Employees.



(b)           The
Company, by means of the Plan, seeks to retain the services of such Employees, to secure and retain the services of new Employees and
to provide incentives for such persons to exert maximum efforts for the success of the Company and its Designated Companies.



2.             Administration.



(a)           The
Board will administer the Plan unless and until the Board delegates administration of the Plan to a Committee or Committees, as provided
in Section 2(c). References herein to the Board shall be deemed to refer to the Committee where such administration has been delegated.



(b)           The
Board will have the power, subject to, and within the limitations of, the express provisions of the Plan:



(i)            to
determine how and when Purchase Rights will be granted and the provisions of each Offering (which need not be identical);



(ii)           to
designate from time to time  which Affiliates will be eligible to participate in the Plan as Designated Companies;



(iii)          to
construe and interpret the Plan and Purchase Rights, and to establish, amend and revoke rules and regulations for its administration.
The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan, in a manner and to the extent
it deems necessary or expedient to make the Plan fully effective;



(iv)          to
settle all controversies regarding the Plan and Purchase Rights granted under the Plan;



(v)           to
suspend or terminate the Plan at any time as provided in Section 12(b);



(vi)          to
amend the Plan at any time as provided in Section 12(a); and













(vii)         to
adopt such rules, procedures and sub-plans as are necessary or appropriate to permit or facilitate participation in the Plan by Employees
who are foreign nationals or employed or located outside Jersey, Channel Islands. Without limiting the foregoing, the Board specifically
is authorized to adopt rules, procedures, and sub-plans regarding, without limitation, eligibility to participate in the Plan, the definition
of Compensation, handling and making of Contributions, establishment of bank or trust accounts to hold Contributions, payment of interest,
conversion of local currency, obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures
and handling of share issuances, any of which may vary according to applicable requirements.



(c)           The
Board may delegate some or all of the administration of the Plan to a Committee or Committees. If administration is delegated to a Committee,
the Committee will have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been
delegated to the Committee, including the power to delegate to a subcommittee any of the administrative powers the Committee is authorized
to exercise (and references in this Plan to the Board will thereafter be to the Committee or subcommittee), subject, however, to such
resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. The Board may retain
the authority to concurrently administer the Plan with the Committee and may, at any time, revest in the Board some or all of the powers
previously delegated. Whether or not the Board has delegated administration of the Plan to a Committee, the Board will have the final
power to determine all questions of policy and expediency that may arise in the administration of the Plan.



(d)           All
determinations, interpretations and constructions made by the Board in good faith will not be subject to review by any person and will
be final, binding and conclusive on all persons.



3.            Shares
Subject to the Plan.



(a)           Subject
to the provisions of Section 11(a) relating to Capitalization Adjustments, the maximum number of Shares that may be issued under
the Plan will not exceed 1,522,991 Shares, plus the number of Shares that are automatically added on January 1st of each year for
a period of up to five years, commencing on the first January 1st following the year in which the Plan is adopted and ending on (and
including) January 1, 2027, in an amount equal one percent (1%) of the total number of issued and outstanding Shares on December 31st
of the preceding calendar year. Notwithstanding the foregoing, the Board may act prior to the first day of any calendar year to provide
that there will be no January 1st increase in the share reserve for such calendar year or that the increase in the share reserve
for such calendar year will be a lesser number of Shares than would otherwise occur pursuant to the preceding sentence.



(b)           If
any Purchase Right granted under the Plan terminates without having been exercised in full, the Shares not purchased under such Purchase
Right will again become available for issuance under the Plan.



(c)           The
shares purchasable under the Plan will be authorized but unissued Shares, including shares repurchased by the Company on the open market.



(d)           The
number of shares of Common Stock available for issue under the Plan in accordance with paragraph (a) above to Eligible Employees
in Australia made in reliance on Division 1A of Part 7.12 of the Corporations Act 2001 (Cth) (“Corporations Act”)
shall not exceed the maximum number permitted to be issued in reliance on that Division unless otherwise authorised under Australian law.





2







4.             Grant
of Purchase Rights; Offering.



(a)           The
Board may from time to time grant or provide for the grant of Purchase Rights to Eligible Employees under an Offering (consisting of one
or more Purchase Periods) on an Offering Date or Offering Dates selected by the Board. Each Offering will be in such form and will contain
such terms and conditions as the Board will deem appropriate. The terms and conditions of an Offering shall be incorporated by reference
into the Plan and treated as part of the Plan. The provisions of separate Offerings need not be identical, but each Offering will include
(through incorporation of the provisions of this Plan by reference in the document comprising the Offering or otherwise) the period during
which the Offering will be effective, and the substance of the provisions contained in Sections 5 through 8, inclusive. The Company may
impose restrictions on eligibility and participation of Eligible Employees who are officers and directors to facilitate compliance with
federal or state securities laws or foreign laws.



(b)           If
a Participant has more than one Purchase Right outstanding under the Plan, unless he or she otherwise indicates in forms delivered to
the Company: (i) each form will apply to all of his or her Purchase Rights under the Plan (and, if there is more than one such form,
the latest filed form will apply unless otherwise indicated), and (ii) a Purchase Right with a lower exercise price (or an earlier-granted
Purchase Right, if different Purchase Rights have identical exercise prices) will be exercised to the fullest possible extent before a
Purchase Right with a higher exercise price (or a later-granted Purchase Right if different Purchase Rights have identical exercise prices)
will be exercised.



(c)           The
Board will have the discretion to structure an Offering so that if the Fair Market Value of a Class A Share on the first Trading
Day of a new Purchase Period within that Offering is less than or equal to the Fair Market Value of a Class A Share on the Offering
Date for that Offering, then (i) that Offering will terminate immediately as of that first Trading Day, and (ii) the Participants
in such terminated Offering will be automatically enrolled in a new Offering beginning on the first Trading Day of such new Purchase Period.



(d)           To
the extent an Offering is made to Eligible Employees in Australia, paragraphs (a) through (c) above apply, provided that to
the extent an Offering cannot be made to an Eligible Employee in reliance on an exception under section 708 of the Corporations Act or
under any other exception available under the Corporations Act, an Offering must be made via an offer document that complies with Division
1A of Part 7.12 of the Corporations Act.



5.             Eligibility.



(a)           Purchase
Rights may be granted only to Employees of the Company or, as the Board may designate in accordance with Section 2(b), to Employees
of a Designed Company. Except as provided in Section 5(b) or as required by applicable law, an Employee will not be eligible
to be granted Purchase Rights unless, on the Offering Date, the Employee has been in the employ of the Company or the Designed Company,
as the case may be, for such continuous period preceding such Offering Date as the Board may require.





3







(b)           The
Board may provide that each person who, during the course of an Offering, first becomes an Eligible Employee will, on a date or dates
specified in the Offering that coincides with the day on which such person becomes an Eligible Employee or which occurs thereafter, receive
a Purchase Right under that Offering, which Purchase Right will thereafter be deemed to be a part of that Offering. Such Purchase Right
will have the same characteristics as any Purchase Rights originally granted under that Offering, as described herein, except that:



(i)            the
date on which such Purchase Right is granted will be the “Offering Date” of such Purchase Right for all purposes, including
determination of the exercise price of such Purchase Right;



(ii)           the
period of the Offering with respect to such Purchase Right will begin on its Offering Date and end coincident with the end of such Offering;
and



(iii)          the
Board may provide that if such person first becomes an Eligible Employee within a specified period of time before the end of the Offering,
he or she will not receive any Purchase Right under that Offering.



(c)           No
Employee will be eligible for the grant of any Purchase Rights if, immediately after any such Purchase Rights are granted, such Employee
owns shares possessing five percent or more of the total combined voting power or nominal value of the authorized issued share capital
of the Company or of any Designated Company.



(d)           Officers
of the Company and any Designated Company, if they are otherwise Eligible Employees, will be eligible to participate in Offerings under
the Plan.



(e)           Notwithstanding
anything in this Section 5 to the contrary, an Eligible Employee (or group of Eligible Employees) may be excluded from participation
in the Plan or an Offering if the Board has determined, in its sole discretion, that participation of such Eligible Employee(s) is
not advisable or practical for any reason.



6.             Purchase
Rights; Purchase Price.



(a)           On
each Offering Date, each Eligible Employee, pursuant to an Offering made under the Plan, will be granted a Purchase Right to purchase
up to 25,000 Shares (or such lesser number of shares determined by the Board prior to the commencement of the Offering), but not exceeding 15%
(or such lesser percentage determined by the Board prior to the commencement of an Offering) of such Employee’s Compensation during
the period that begins on the Offering Date (or such later date as the Board determines for a particular Offering) and ends on the date
stated in the Offering, which date will be no later than the end of the Offering.



(b)           The
Board will establish one or more Purchase Dates during an Offering on which Purchase Rights granted for that Offering will be exercised
and Shares will be purchased in accordance with such Offering. Unless the Board determines otherwise, Offerings and Purchase Periods shall
be concurrent six-month periods, commencing on January 1 and July 1 of each year, with the first such Offering and Purchase
Period commencing on January 1, 2022.





4







(c)           In
connection with each Offering made under the Plan, the Board may specify (i) a maximum number of Shares that may be purchased by
any Participant on any Purchase Date during such Offering, (ii) a maximum aggregate number of Shares that may be purchased by all
Participants pursuant to such Offering and/or (iii) a maximum aggregate number of Shares that may be purchased by all Participants
on any Purchase Date under the Offering. Unless the Board determines otherwise, the maximum number of shares that all Participants may
purchase in the aggregate on any Purchase Date is ten percent (10%) of the available shares reserved under this Plan as of the date of
the commencement of the Offering. If the aggregate purchase of Shares issuable on exercise of Purchase Rights granted under the Offering
would exceed any such maximum aggregate number, then, in the absence of any Board action otherwise, a pro rata (based on each Participant’s
accumulated Contributions) allocation of the Shares (rounded down to the nearest whole share) available will be made in as nearly a uniform
manner as will be practicable and equitable.



(d)           The
purchase price of Shares acquired pursuant to Purchase Rights will not be less than the lesser of:



(i)            an
amount equal to 85% of the Fair Market Value of the Shares on the Offering Date; or



(ii)           an
amount equal to 85% of the Fair Market Value of the Shares on the applicable Purchase Date.



7.             Participation;
Withdrawal; Termination.



(a)           An
Eligible Employee may elect to participate in an Offering and authorize payroll deductions as the means of making Contributions by completing
and delivering to the Company, within the time specified in the Offering, an enrollment form provided by the Company. The enrollment form
will specify the amount of Contributions not to exceed the maximum amount specified by the Board. To the extent any Participant is an
Eligible Employee in Australia, such Participant’s Contributions must be held in a dedicated trust account established by the Company
with an authorised deposit-taking institution in Australia to the extent required by Division 1A of Part 7.12 of the Corporations
Act. Each Participant’s Contributions will be credited to a bookkeeping account for such Participant under the Plan and will be
deposited with the general funds of the Company except where applicable law or regulations requires that Contributions be deposited with
a third party. If permitted in the Offering, a Participant may begin such Contributions with the first payroll occurring on or after the
Offering Date (or, in the case of a payroll date that occurs after the end of the prior Offering but before the Offering Date of the next
new Offering, Contributions from such payroll will be included in the new Offering). If permitted in the Offering, a Participant may thereafter
reduce (including to zero) or increase his or her Contributions. Except as otherwise determined by the Board, a Participant only will
be permitted to increase or reduce his or her Contributions once per Offering. If required under applicable law or regulations or if specifically
provided in the Offering, in addition to or instead of making Contributions by payroll deductions, a Participant may make Contributions
through payment by cash, check or wire transfer prior to a Purchase Date.





5







(b)           During
an Offering, a Participant may cease making Contributions and withdraw from the Offering by delivering to the Company a withdrawal form
provided by the Company. The Company may impose a deadline before a Purchase Date for withdrawing. On such withdrawal, such Participant’s
Purchase Right in that Offering will immediately terminate, and the Company will distribute as soon as practicable to such Participant
all of his or her accumulated but unused Contributions, without interest or earnings (unless otherwise required by applicable law) and
such Participant’s Purchase Right in that Offering shall thereupon terminate. A Participant’s withdrawal from that Offering
will have no effect on his or her eligibility to participate in any other Offerings under the Plan, but such Participant will be required
to deliver a new enrollment form to participate in subsequent Offerings.



(c)           Unless
otherwise required by applicable law or regulations, Purchase Rights granted pursuant to any Offering under the Plan will terminate immediately
if the Participant either (i) is no longer an Employee for any reason or for no reason (subject to any post-employment participation
period required by applicable law) or (ii) is otherwise no longer eligible to participate. The Company will distribute as soon as
practicable to such individual all of his or her accumulated but unused Contributions without interest or earnings (unless otherwise required
by applicable law).



(d)           Unless
otherwise determined by the Board, a Participant whose employment transfers or whose employment terminates with an immediate rehire (with
no break in service) by or between the Company and a Designated Company or between Designated Companies will not be treated as having
terminated employment for purposes of participating in the Plan or an Offering.



(e)           During
a Participant’s lifetime, Purchase Rights will be exercisable only by such Participant. Purchase Rights are not transferable by
a Participant, except by will, by the laws of descent and distribution or, if permitted by the Company, by a beneficiary designation as
described in Section 10.



(f)            Unless
otherwise specified in the Offering or required by applicable law or regulations, the Company will have no obligation to pay interest
on Contributions.



8.             Exercise
of Purchase Rights.



(a)           On
each Purchase Date, each Participant’s accumulated Contributions will be applied to the purchase of Shares, up to the maximum number
of Shares permitted by the Plan and the applicable Offering, at the purchase price specified in the Offering. No fractional shares will
be issued unless specifically provided for in the Offering. Unless the Board determines otherwise, shares will be issued to and held under
the name of a Plan Broker designated by the Company or to a designated agent of the Company, and the Company may utilize electronic or
automated methods of share transfer. Unless the Board determines otherwise, a Participant must retain such shares with the Plan Broker
until the later of the two-year anniversary of the date of grant of the associated Purchase Rights or the one-year anniversary of the
exercise date of the associated Purchase Rights, but unless the Board elects to restrict dispositions during such period, a Participant
may sell the shares at any time after the shares are issued to a Plan Broker.





6







(b)           Unless
otherwise provided in the Offering, if any amount of accumulated Contributions remains in a Participant’s account after the purchase
of Shares on the final Purchase Date of an Offering, then such remaining amount will not roll over to the next Offering and will instead
be distributed in full to such Participant as soon as practicable after the final Purchase Date of such Offering without interest or earnings
(unless otherwise required by applicable law or regulations).



(c)           No
Purchase Rights may be exercised to any extent unless the Shares to be issued on such exercise under the Plan are covered by an effective
registration statement pursuant to the Securities Act, and the Plan is in material compliance with all applicable U.S. federal, state,
foreign and other securities and other laws applicable to the Plan. If on a Purchase Date the Shares are not so registered or the Plan
is not in such compliance, no Purchase Rights will be exercised on such Purchase Date, and the Purchase Date will be delayed until the
Shares are subject to such an effective registration statement, and the Plan is in material compliance. If, on the Purchase Date, as delayed
to the maximum extent permissible, the Shares are not registered and the Plan is not in material compliance with all applicable laws and
regulations, as determined by the Company in its sole discretion, no Purchase Rights will be exercised and all accumulated but unused
Contributions will be distributed to the Participants without interest.



9.            Covenants
of the Company.



The Company will seek to obtain
from each U.S. federal, state, foreign or other regulatory commission or agency or governmental body having jurisdiction over the Plan
such authority as may be required to grant Purchase Rights and issue and sell Shares thereunder unless the Company determines, in its
sole discretion, that doing so is not practical or would cause the Company to incur costs that are unreasonable. If, after commercially
reasonable efforts, the Company is unable to obtain the authority that counsel for the Company deems necessary for the grant of Purchase
Rights or the lawful issuance and sale of Shares under the Plan, and at a commercially reasonable cost, the Company will be relieved from
any liability for failure to grant Purchase Rights and/or to issue and sell Shares on exercise of such Purchase Rights.



10.          Designation
of Beneficiary.



(a)           The
Company may, but is not obligated to, permit a Participant to submit a form designating a beneficiary who will receive any Shares and/or
Contributions from the Participant’s account under the Plan if the Participant dies before such shares and/or Contributions are
delivered to the Participant. The Company may, but is not obligated to, permit the Participant to change such designation of beneficiary.
Any such designation and/or change must be on a form approved by the Company.



(b)           If
a Participant dies, and in the absence of a valid beneficiary designation, the Company will deliver any Shares and/or Contributions to
the executor or administrator of the estate of the Participant. If no executor or administrator has been appointed (to the knowledge of
the Company), the Company, in its sole discretion, may issue or deliver (as the case may be) such Shares and/or Contributions, without
interest, to the Participant’s spouse, dependents or relatives, or if no spouse, dependent or relative is known to the Company,
then to such other person as the Company may designate.





7







11.          Adjustments
on Changes in Shares; Corporate Transactions.



(a)           In
the event of a Capitalization Adjustment, the Board will appropriately and proportionately adjust: (i) the class(es) and maximum
number of securities subject to the Plan pursuant to Section 3(a), (ii) the class(es) and maximum number of securities reserved
automatically each year pursuant to Section 3(a), (iii) the class(es) and number of securities subject to, and the purchase
price applicable to outstanding Offerings and Purchase Rights, and (iv) the class(es) and number of securities that are the subject
of the purchase limits under each ongoing Offering. The Board will make these adjustments, and its determination will be final, binding
and conclusive.



(b)           In
the event of a Corporate Transaction, then: (i) any surviving corporation or acquiring corporation (or the surviving or acquiring
corporation’s parent company) may assume or continue outstanding Purchase Rights or may substitute similar rights (including a right
to acquire the same consideration paid to the shareholders in the Corporate Transaction) for outstanding Purchase Rights, or (ii) if
any surviving or acquiring corporation (or its parent company) does not assume or continue such Purchase Rights or does not substitute
similar rights for such Purchase Rights, then the Participants’ accumulated Contributions will be used to purchase Shares (rounded
down to the nearest whole share) within ten business days prior to the Corporate Transaction under the outstanding Purchase Rights, and
the Purchase Rights will terminate immediately after such purchase.



12.          Amendment,
Termination or Suspension of the Plan.



(a)           The
Board may amend the Plan at any time in any respect the Board deems necessary or advisable. However, except as provided in Section 11(a) relating
to Capitalization Adjustments, shareholder approval will be required for any amendment of the Plan for which shareholder approval is required
by applicable law, regulations or listing requirements.



(b)           The
Board may suspend or terminate the Plan at any time. No Purchase Rights may be granted under the Plan while the Plan is suspended or after
it is terminated.



(c)           Any
benefits, privileges, entitlements and obligations under any outstanding Purchase Rights granted before an amendment, suspension or termination
of the Plan will not be materially impaired by any such amendment, suspension or termination except (i) with the consent of the person
to whom such Purchase Rights were granted, (ii) as necessary to comply with any laws, listing requirements, or governmental regulations
including without limitation any such regulations or other guidance that may be issued or amended after the date the Plan is adopted by
the Board, or (iii) as necessary to obtain or maintain favorable tax, listing, or regulatory treatment. Notwithstanding anything
in the Plan or any Offering Document to the contrary, the Board will be entitled to: (i) establish the exchange ratio applicable
to amounts withheld in a currency other than U.S. dollars; (ii) permit Contributions in excess of the amount designated by a
Participant in order to adjust for mistakes in the Company’s processing of properly completed Contribution elections; (iii) establish
reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase
of Shares for each Participant properly correspond with amounts withheld from the Participant’s Contributions; and (iv) establish
other limitations or procedures as the Board determines in its sole discretion advisable that are consistent with the Plan. The actions
of the Board pursuant to this paragraph will not be considered to alter or impair any Purchase Rights granted under an Offering as they
are part of the initial terms of each Offering and the Purchase Rights granted under each Offering.





8







13.          Tax
Qualification; Tax Withholding.



(a)           Although
the Company may endeavor to (i) qualify a Purchase Right for special tax treatment or avoid adverse tax treatment, the Company makes
no representation to that effect and expressly disavows any covenant to maintain special or to avoid unfavorable tax treatment, notwithstanding
anything to the contrary in this Plan. The Company will be unconstrained in its corporate activities without regard to the potential negative
tax impact on Participants.



(b)           Each
Participant will make arrangements, satisfactory to the Company and any applicable Designated Company, to enable the Company or the Designated
Company to fulfill any withholding obligation for Tax-Related Items. Without limitation to the foregoing, in the Company’s sole
discretion and subject to applicable law, such withholding obligation may be satisfied in whole or in part by (i) withholding from
the Participant’s salary or any other cash payment due to the Participant from the Company or a Designated Company; (ii) withholding
from the proceeds of the sale of Shares acquired under the Plan, either through a voluntary sale or a mandatory sale arranged by the Company;
or (iii) any other method deemed acceptable by the Board. The Company shall not be required to issue any Shares under the Plan until
such obligations are satisfied.



(c)           This
Plan, as it relates to Purchase Right issued to a Participant who is an Eligible Employee in Australia, is a plan to which Subdivision
83A-C of the Income Tax Assessment Act 1997 (“Tax Act”) applies (subject to the conditions in the Tax Act),
unless the Offering provides that Subdivision 83A-C is not to apply to that Purchase Right.



14.          Effective
Date of Plan; Term of Plan



The Plan will become effective
immediately prior to and contingent on the occurrence of the Closing Date. No Purchase Rights will be exercised unless and until the Plan
has been approved by the shareholders of the Company, which approval must be within 12 months before or after the date the Plan is adopted
(or if required under Section 12(a) above, materially amended) by the Board. If not terminated earlier pursuant to Section 12,
the Plan will have a term that expires on the tenth anniversary of its adoption by the Board.



15.          Miscellaneous
Provisions.



(a)           Proceeds
from the sale of Shares pursuant to Purchase Rights will constitute general funds of the Company.





9







(b)           A
Participant will not be deemed to be the holder of, or to have any of the rights of a holder with respect to, Shares subject to Purchase
Rights unless and until the Participant’s Shares acquired on exercise of Purchase Rights are recorded in the register of members
of the Company or branch register maintained by its transfer agent.



(c)           The
Plan and Offering do not constitute an employment contract. Nothing in the Plan or in the Offering will in any way alter the at-will nature
of a Participant’s employment, if applicable, or be deemed to create in any way whatsoever any obligation on the part of any Participant
to continue in the employ of the Company, a Designated Company or an Affiliate, or on the part of the Company, a Designated Company or
an Affiliate to continue the employment of a Participant.



(d)           This
Plan and all determinations made and actions taken pursuant to this Plan shall be governed by the internal laws of the Jersey, Channel
Islands, without giving effect to principles of conflicts of laws, and construed accordingly.



(e)           If
any particular provision of the Plan is found to be invalid or otherwise unenforceable, such provision will not affect the other provisions
of the Plan, but the Plan will be construed in all respects as if such invalid provision was omitted.



(f)            If
any provision of the Plan does not comply with applicable law or regulations, such provision shall be construed in such a manner as to
comply with applicable law or regulations.

nonrecurring cash dividend, share subdivision, liquidating dividend, share consolidation, exchange of shares, change in corporate structure
or other similar equity restructuring transaction, as that term is used in Financial Accounting Standards Board Accounting Standards Codification
