WHEREAS,
concurrently with the execution and delivery of this Share Purchase Agreement and the Merger Agreement, as part of the Secondary
Transactions, certain other existing shareholders of Issuer (each, an “Other Seller” and each purchaser thereunder,
“Other Purchaser”) are, severally and not jointly, entering into (i) a separate share purchase agreement with
the Issuer (the “Employee Share Purchase Agreement”) substantially similar to this Share Purchase Agreement,
providing for the sale by Other Sellers of two million one hundred twenty thousand (2,120,000) Ordinary Shares, in the aggregate
(the “Aggregate Employee Share Amount”), for an aggregate purchase price of Twenty One Million Two Hundred
Thousand Dollars ($21,200,000) and (ii) that certain Side Letter executed in connection with the Secondary Transactions pursuant
to which the purchasers thereunder (including the Purchaser) receive registration rights with respect to the Secondary Shares,
in each case, after the Issuer has effected the Forward Stock Split (the “Secondary Side Letter”).

 

NOW,
THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions,
herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

 

1. Purchase
of Shares.

 

1.1 Purchase.
Subject to the terms hereof and any adjustments pursuant to Section 1.2, at the Closing, (a) each Purchaser, severally
and not jointly, hereby irrevocably agrees to subscribe for and purchase the number of Shares set forth on such Purchaser’s
signature page from the Sellers in accordance with the allocations set forth on each such Purchaser’s Closing Notice, (b)
each Seller, severally and not jointly, hereby agrees to sell such Seller’s Secondary Shares to the Purchasers in accordance
with the allocations set forth in each such Seller’s Closing Notice and (c) solely in the event of a Minimum Cash Adjustment
(as defined below), Issuer hereby irrevocably agrees to issue and sell the Primary Shares (as defined below) to the Purchasers
in accordance with the allocations set forth in their respective Closing Notices (the transactions described in clauses (a), (b)
and (c) above, collectively, the “Purchase”). For the avoidance of doubt, each Seller acknowledges and agrees
that the payment of each such Secondary Purchase Price shall be subject to such taxes and withholding taxes pursuant to applicable
law (domestic or foreign) or pursuant to Israeli Tax. Such taxes duly deducted and withheld, if any, shall be deemed, for all
purposes, as having been paid to such Seller in connection with such Secondary Purchase Price.

 

1.2 Minimum
Cash Adjustment. If the Shortfall Amount (as defined below) is greater than zero (a “Minimum Cash Adjustment”),
then:

 

1.2.1 the
Issuer shall issue and sell to the Purchasers a number of Ordinary Shares equal to the quotient of (i) the Shortfall Amount divided
by (ii) the Ordinary Share Price (as calculated after giving effect to the Forward Stock Split) (the “Primary Shares”),
in consideration of the payment of an amount equal to the Shortfall Amount by or on behalf of the Purchasers to the Issuer; and

 

    2

     

    

 

1.2.2 the
aggregate number of Secondary Shares to be sold by the Sellers pursuant to Section 1.1 shall be automatically reduced by
the number of Primary Shares, on a pro rata basis, such that the sum of the Primary Shares plus the Secondary Shares
plus the Aggregate Employee Share Amount equals the Aggregate Secondary Share Amount. For the avoidance of doubt, if the
Shortfall Amount is greater than the Aggregate Institutional Amount, the Sellers herein will not sell any Secondary Shares hereunder.

 

For
purposes of this Section 1.2:

 

(a) The
“Shortfall Amount” is equal to (i) $200,000,000 minus (ii) the Total Balance Sheet Proceeds, provided
that the Shortfall Amount shall not be less than zero (but may be equal to zero).

 

(b) The
“Total Balance Sheet Proceeds” is equal to the sum of (A) the funds contained in the Trust Account as of immediately
after giving effect to the ION Shareholder Redemptions and the payment of the ION Transaction Costs, the Company Transaction Costs
and the Unpaid ION Liabilities plus (B) the PIPE Investment Amount.

 

2. Representations,
Warranties and Agreements.

 

2.1 Purchasers’
Representations, Warranties and Agreements. Each Purchaser, severally and not jointly, hereby represents and warrants to the

such Purchaser. If such Purchaser is an individual, the signature on this Share Purchase Agreement is genuine, and such Purchaser

2.1.3 The
execution, delivery and performance by such Purchaser of this Share Purchase Agreement (including compliance by such Purchaser
with all of the provisions hereof) and the consummation of the transactions contemplated herein do not and will not (i) conflict
with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the

any disclosure or offering document in connection with the offer and sale of such Shares. Such Purchaser further acknowledges

exists.

it maintains policies and procedures reasonably designed to ensure that the funds held by such Purchaser and used to purchase

effect on the legal authority of the Issuer to enter into and perform its obligations under this Share Purchase Agreement (a “Issuer
Material Adverse Effect”), (ii) result in any violation of the provisions of the organizational documents of the Issuer
or any of its subsidiaries, as applicable, or (iii) result in any violation of any statute or any judgment, order, rule or regulation
of any court or governmental agency or body, domestic or foreign, having jurisdiction over the Issuer or any of its subsidiaries,
as applicable, or any of their respective properties that would reasonably be expected to have an Issuer Material Adverse Effect.

2.3.5 There
are no securities or instruments issued by or to which the Issuer is a party containing anti-dilution or similar provisions that
will be triggered by the issuance of (i) the Shares, (ii) any Ordinary Shares to be issued pursuant to the Employee Share Purchase
Agreement or (iii) any shares of capital stock of the Issuer to be issued pursuant to the other Transactions, in each case, that
have not been or will not be validly waived or terminated prior to the Closing Date.

 

2.3.6 As
of the date of this Share Purchase Agreement, the authorized capital shares of the Issuer consists of (i) 65,366,595 Ordinary
Shares of no par value (“Existing Ordinary Shares”) and (ii) 45,688,037 preferred shares of no par value (“Preferred
Shares”). As of the date of this Share Purchase Agreement: (i) 14,389,390 Existing Ordinary Shares are issued and outstanding
and (ii) 44,978,000 Preferred Shares are issued and outstanding (consisting of (a) 3,687,739 series A convertible preferred shares

Immediately prior to the Closing, the Preferred Shares in (ii) will be converted to Ordinary Shares.

 

2.3.7 Concurrently
with the execution and delivery of this Share Purchase Agreement, the Issuer is entering into (i) separate subscription agreements
with certain other “qualified institutional buyers” (as defined in Rule 144A under the Securities Act) or “accredited
investors” (within the meaning of Rule 501(a) under the Securities Act) (“Primary Subscribers”) pursuant
to which each such Primary Subscriber has agreed to purchase Issuer’s Ordinary Shares at the Closing at the same per share
purchase price as the Purchasers hereunder, and the aggregate amount of securities to be sold by the Issuer to the Primary Subscribers
equals, as of the date hereof, thirteen million five hundred thousand (13,500,000) Ordinary Shares (the “Primary Subscription
Agreements”), (ii) the Employee Share Purchase Agreement and (iii) the Secondary Side Letter. Other than the Primary
Subscription Agreements, the Other Employee Share Purchase Agreement, the Secondary Side Letter, the Merger Agreement, the Investors’
Rights Agreement and any other agreement contemplated by the Merger Agreement, neither the Company nor the Issuer has entered
into any side letter or similar agreement with any other investor (including any Other Seller) in connection with such investor’s
direct or indirect investment in the Issuer (other than any side letter or similar agreement relating to the transfer to any investor
of (a) securities of the Issuer by existing securityholders of the Issuer, which may be effectuated as a forfeiture to the Issuer
and reissuance or (b) securities to be issued to the direct or indirect securityholders of the Issuer pursuant to the Merger Agreement).
Except as may be required by applicable law or regulatory requirements in connection with the Closing, the Employee Share Purchase
Agreement (as may be amended in accordance with its terms) does not include terms and conditions that are materially more advantageous
to any Other Sellers or Other Purchasers than the Sellers and Purchasers hereunder, as applicable, and the Employee Share Purchase
Agreement has not been amended or modified in any material respect following the date of this Share Purchase Agreement.

no registration under the Securities Act and no prospectus approved under the Securities Law is required for the offer and sale
of the Primary Shares issued by the Issuer to the Purchasers.

 

2.3.9 Neither
the Issuer nor any person acting on its behalf has, directly or indirectly, made any offers or sales of any securities of the
Issuer or solicited any offers to buy any securities of the Issuer under circumstances that would adversely affect reliance by
(i) the Sellers on Section 4(a)(1 1/2) or (ii) the Issuer on Section 4(a)(2) of the Securities Act for the exemption from registration
for the transactions contemplated hereby or would require registration of the sale of the Secondary Shares or issuance of the
Primary Shares under the Securities Act.

 

2.3.10 Neither
the Issuer, nor any person acting on its behalf has conducted any general solicitation or general advertising, including methods
described in section 502(c) of Regulation D under the Securities Act, in connection with the offer or sale of any of the Shares
and neither the Issuer, nor any person acting on its behalf has offered any of the Shares in a manner involving a public offering
under, or in a distribution in violation of, the Securities Act or any state securities laws.

 

2.3.11 The
Issuer is classified as a Subchapter C corporation for U.S. federal income tax purposes.

 

2.3.12 The
Issuer is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration
with, any court or other federal, state, local or other governmental authority, self-regulatory organization or other person in
connection with the execution, delivery and performance by the Issuer of this Share Purchase Agreement (including, without limitation,
the issuance of the Shares), other than filings (i) with the Commission of the Registration Statement (as defined in the Secondary
Side Letter), (ii) required by applicable state or federal securities laws, (iii) required in accordance with the Merger Agreement,
(iv) required by the New York Stock Exchange (the “NYSE”) or The Nasdaq Stock Market (“NASDAQ”)
and (v) the failure of which to obtain would not be reasonably expected to have, individually or in the aggregate, an Issuer Material
Adverse Effect.

 

2.3.13 As
of the Closing, the Issuer’s Ordinary Shares will be registered pursuant to Section 12(b) of the Exchange Act and are listed
for trading on the NYSE or NASDAQ under the symbol “TBLA”. There is no suit, action, proceeding or investigation pending
or to the knowledge of the Issuer, threatened against the Issuer by the NYSE, NASDAQ or the Commission with respect to any intention
by such entity to deregister the Ordinary Shares or prohibit or terminate the listing of Ordinary Shares on the NYSE or NASDAQ.

 

2.3.14 Other
than the Placement Agents, Issuer represents and warrants to the other parties hereto that no broker, finder or other financial
consultant has acted on its behalf in connection with this Share Purchase Agreement or the transactions contemplated hereby in
such a way as to create any liability on any other parties hereto.

 

2.3.15 Issuer
is not currently (and at all times through Closing will refrain from being or becoming) a member of a “group” (within
the meaning of Section 13(d)(3) or Section 14(d)(2) of the Exchange Act, or any successor provision), including any group acting
for the purpose of acquiring, holding or disposing of equity securities of the Company (within the meaning of Rule 13d-5(b)(1)
under the Exchange Act).

 

    12

     

    

 

2.3.16 The
Shares to be issued to the Purchasers pursuant to the terms and conditions of this Share Purchase Agreement will not be subject
to any ‘lock up’ restrictions.

 

3. Settlement
Date, Delivery and Closing.

 

3.1 The
closing of the Purchase contemplated hereby (the “Closing”) shall occur immediately prior to or concurrently
with the consummation of the Merger (the date of such Closing, the “Closing Date”). At least five (5) Business
Days prior to the date that the Issuer reasonably expects all conditions to the closing of the Merger to be satisfied, a written
notice (the “Closing Notice”) shall be delivered from (or on behalf of) the Issuer to (a) each Seller, which
shall include a schedule that sets forth (i) the number of Secondary Shares to be sold by each such Seller to each Purchaser (after
giving effect to the Forward Stock Split and any pro rata adjustments in accordance with Section 1.2 hereof) and
(ii) the Secondary Purchase Price payable by each Purchaser in respect thereof, and (b) each Purchaser, which shall include (i)
a schedule that sets forth the number of Secondary Shares to be purchased by each such Purchaser from each Seller and the Primary
Shares to be purchased by such Purchaser (in each case, after giving effect to the Forward Stock Split and any pro rata
adjustments in accordance with Section 1.2 hereof, as applicable), (ii) the aggregate purchase price payable in respect
of the Shares to be acquired by such Purchaser (the “Purchase Price”), and (iii) wire instructions with respect
to the Purchase Price to be paid by such Purchaser. At least two (2) Business Days prior to the anticipated Closing Date, each
Purchaser shall deliver such Purchaser’s Purchase Price for the Shares, as set forth in the Closing Notice received by such
Purchaser, by wire transfer of United States dollars in immediately available funds to the account(s) specified in the Closing
Notice (the “Prepaid Funds”). The Prepaid Funds shall be held by a Paying Agent appointed by the Issuer for
the benefit of, and on behalf of, the Sellers (the “Paying Agent”) whereupon (x) subject to any withholding
required under any applicable law, each Seller (or any nominee of the Seller) shall receive from the Prepaid Funds an amount equal
to the Secondary Purchase Price payable thereto as set forth in the Closing Notice delivered to each such Seller and (y) the Issuer
shall receive the Prepaid Funds remaining after giving effect to the payments contemplated by clause (x) above, if any. Immediately
following the Closing, upon satisfaction of the foregoing conditions with respect to payment set forth in this Section 2.3,
the Shares shall be issued to each Purchaser and subsequently registered in book entry form in the name of each Purchaser (or
its nominee in accordance with its delivery instructions) or to a custodian designated by such Purchaser, as applicable and as
set forth on each Purchaser’s signature page hereto, on Issuer’s share register (which book entry records shall contain
an appropriate notation concerning transfer restrictions of the Shares, in accordance with applicable securities laws of the states
of the United States and other applicable jurisdictions), and will provide to each such Purchaser evidence of such issuance from
the Issuer’s transfer agent.

 

3.1.1 
Notwithstanding the foregoing, with respect to Israeli Tax and in accordance with the Paying Agent undertaking provided by the
Paying Agent to the Purchasers as required under Section 6.2.4.3 of the Income Tax Circular 19/2018 (Transaction for Sale of Rights
in a Corporation that includes Consideration that will be transferred to the Seller at Future Dates) (the “Paying Agent
Undertaking”), the Purchase Price payable to each Seller shall be paid to, and retained by, the Paying Agent, in each
case, for the benefit of each such Seller for a period of one-hundred eighty (180) days from the Closing Date or an earlier date
if requested in writing by such Seller (the “Withholding Drop Date”) (during which time, unless requested otherwise
by the Israeli Tax Authority in writing, no payments shall be made by the Paying Agent to any payment recipient and no amounts
for Israeli Taxes shall be withheld from the payments deliverable pursuant to this Agreement‎, except as provided herein and
during which time each Seller may obtain a Valid Tax Certificate). If such Seller delivers a Valid Tax Certificate to the Paying
Agent no later than three (3) Business Days prior to the Withholding Drop Date, then the deduction and withholding of any Israeli
Taxes shall be made only in accordance with the provisions of such Valid Tax Certificate and the balance ‎of the payment that
is not withheld shall be paid to such Seller. If such Seller (i) does not provide the Paying Agent with a Valid Tax Certificate
in a timely manner or (ii) submits a written request to the Paying Agent to release such Seller’s Secondary Purchase Price
prior to ‎the Withholding Drop Date and fails to submit a Valid Tax Certificate no later than three (3) Business Days before
such time, then the amount of Israeli Tax to be withheld from such payment shall be according to the Income Tax Regulations )Withholding
from Payment for Services or Assets) - 1977 and calculated in New Israeli Shekels, which amount shall be timely delivered or caused
to be delivered to the Israeli Tax Authority by the Paying Agent, and the balance ‎of the payment that is not withheld shall
be paid to such Seller; provided, any currency conversion commissions will be borne by such Seller and deducted from the
Secondary Purchase Price to be remitted to such Seller. For clarity, unless otherwise specified in this Agreement or as required
by applicable law, all references to currency, monetary values and dollars set forth herein shall mean United States dollars and
all payments hereunder shall be made in United States dollars. Each party hereto agrees that to the extent this Agreement provides
for any valuation, measurement or test as of a given date based on an amount specified in United States dollars and the subjects
of such valuation, measurement or test are comprised of items or matters that are, in whole or in part, denominated in New Israeli
Shekels (as in this Section 3.1.1), such New Israeli Shekel amounts shall be converted into United States dollars using
the New Israeli Shekel to United States dollar exchange rate published by the Bank of Israel on the payment date of such payment.

 

    13

     

    

 

3.2 In
the event that the consummation of the Merger does not occur within five (5) Business Days after the anticipated Closing Date
specified in the Closing Notice, unless otherwise agreed to in writing by the Issuer, on behalf of the Sellers and itself, and
the Purchasers, the Issuer shall cause the Paying Agent to promptly (but in no event later than eight (8) Business Days after
the anticipated Closing Date specified in the Closing Notice) return the Purchase Price so delivered by each Purchaser by wire
transfer in immediately available funds to the account specified by each Purchaser, and any book entries shall be deemed repurchased
and cancelled. Notwithstanding such repurchase, return or cancellation, each Purchaser acknowledges and agrees that (i) a failure
to close on the anticipated Closing Date specified in the Closing Notice shall not, by itself, be deemed to be a failure of any
of the conditions to Closing set forth in this Section 3 to be satisfied or waived on or prior to the Closing Date and
(ii) unless and until this Share Purchase Agreement is terminated in accordance with Section 5 herein, such Purchaser shall
remain obligated (A) to redeliver funds to the Paying Agent, on behalf of the Sellers and the Issuer, following the Issuer’s
delivery to such Purchaser of a new Closing Notice and (B) to consummate the Closing on the Closing Date and immediately following
the consummation of the Merger. For the purposes of this Share Purchase Agreement, “Business Day” means any
day other than a Friday, Saturday, Sunday or any other day on which commercial banks are required or authorized to close in the
State of New York, Tel-Aviv, Israel, or the Cayman Islands.

 

3.3 Conditions
to Closing of the Purchasers. Each Purchaser’s obligation to purchase the Shares at the Closing is subject to the fulfillment
or (to the extent permitted by applicable law) written waiver by such Purchaser, on or prior to the Closing Date, of each of the
following conditions:

 

3.3.1 The
representations and warranties made by the Seller in Section 2.2 hereof and by the Issuer in Section 2.3 hereof shall be true
and correct in all material respects when made (other than representations and warranties that are qualified as to materiality,
Seller Material Adverse Effect or Issuer Material Adverse Effect, which representations and warranties shall be true and correct
in all respects) and shall be true and correct in all material respects on and as of the Closing Date (unless they specifically
speak as of another date in which case they shall be true and correct in all material respects as of such date) (other than representations
and warranties that are qualified as to materiality, Seller Material Adverse Effect or Issuer Material Adverse Effect, which representations
and warranties shall be true and correct in all respects) with the same force and effect as if they had been made on and as of
such date), but, in each case (x) without giving effect to consummation of the Transactions and (y) other than failures to be
true and correct that would not result, individually or in the aggregate, in a Seller Material Adverse Effect or an Issuer Material
Adverse Effect.

 

3.3.2 The
Issuer and the Sellers shall have performed, satisfied and complied in all material respects with the covenants, agreements and
conditions required by this Share Purchase Agreement to be performed, satisfied or complied with by the Issuer and the Sellers
at or prior to the Closing, except where the failure of such performance or compliance would not or would not reasonably be expected
to prevent, materially delay, or materially impair the ability of the Issuer and the Sellers to consummate the Closing.

 

    14

     

    

 

3.3.3 There
shall not be in force any order, judgment or injunction by or with any governmental authority in the United States, Israel or
the Cayman Islands enjoining or prohibiting the consummation of the Purchase.

 

3.3.4 There
shall not have occurred any suspension of the Shares for sale or trading on the NYSE or NASDAQ and, to the Issuer’s knowledge,
no proceedings for any such purpose shall have been initiated or threatened.

 

3.3.5 The
Transactions set forth in the Merger Agreement shall have been or will be consummated concurrently with the Closing (it being
understood that in the event such Transactions have not been or would not reasonably be expected to be consummated due to the
assertion by the Company that any of the conditions set forth in Section 7.03 of the Merger Agreement has not been or would not
be satisfied, the Issuer acknowledges and agrees that the Purchaser shall not have any obligation to consummate the Closing or
any liability with respect thereto; provided that, subject to Section 4 hereof, if the Issuer and the Company subsequently consummate
the Transaction, the foregoing shall no longer apply); and the terms of the Merger Agreement (including the conditions thereto)
shall not have been amended, and the Company shall not have waived any such term, in a manner that is materially adverse to any
Purchaser (in its capacity as such).

 

3.4 Conditions
to Closing of the Sellers and the Issuer. Each Seller’s obligation to sell such Secondary Shares, and the Issuer’s
obligation to issue and sell Primary Shares in the event there is a Minimum Cash Adjustment, as applicable, at the Closing is
subject to the fulfillment or (to the extent permitted by applicable law) written waiver by such Seller and, if applicable, the
Issuer, on or prior to the Closing Date, of each of the following conditions:

 

3.4.1 The
Purchasers shall have performed, satisfied and complied in all material respects with the covenants, agreements and conditions
required by this Share Purchase Agreement to be performed, satisfied or complied with by the Purchasers at or prior to the Closing,
except where the failure of such performance or compliance would not or would not reasonably be expected to prevent, materially
delay, or materially impair the ability of the Purchasers to consummate the Closing.

 

3.4.2 There
shall not be in force any order, judgment or injunction by or with any governmental authority in the United States, Israel or
the Cayman Islands enjoining or prohibiting the consummation of the Purchase.

 

4. Termination.
This Share Purchase Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of
the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earlier
to occur of (i) such date and time as the Merger Agreement is validly terminated in accordance with its terms, (ii) upon the mutual
written agreement of each of the parties hereto to terminate this Share Purchase Agreement, (iii) if any of the conditions to
Closing set forth in Section 3.3 or Section 3.4 are not satisfied or waived by the party entitled to grant such waiver on or prior
to the Closing and, as a result thereof, the transactions contemplated by this Share Purchase Agreement are not consummated at
the Closing, and (iv) if the Closing shall not have occurred on or before July 9, 2021; provided, that (a) Section 3.2
shall survive any termination of this Agreement that occurs following the funding by any Purchaser of the Purchase Price payable
thereby in accordance with the terms and conditions of Section 3.1, and (b) nothing herein will relieve any party from liability
for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity
to recover losses, liabilities or damages arising from such breach. The Issuer shall notify the Sellers and the Purchasers of
the termination of the Merger Agreement promptly after the termination of such agreement.

 

    15

     

    

 

5. Miscellaneous.

 

5.1 Further
Assurances. At the Closing, the parties hereto shall execute and deliver such additional documents and take such additional
actions as the parties reasonably may deem to be practical and necessary in order to consummate the Purchase as contemplated by
this Share Purchase Agreement.

 

5.1.1 Each
Purchaser acknowledges that the Sellers, the Issuer, the Company and the Placement Agents will rely on the acknowledgments, understandings,
agreements, representations and warranties made by such Purchaser contained in this Share Purchase Agreement. Prior to the Closing,
each Purchaser agrees to promptly notify the Sellers and the Issuer if any of the acknowledgments, understandings, agreements,
representations and warranties made by such Purchaser set forth herein are no longer accurate in all material respects. Each Purchaser
further acknowledges and agrees that each Placement Agent is a third-party beneficiary of the representations and warranties of
each Purchaser contained in Section 2.1.8 and Section 2.1.9 of this Share Purchase Agreement to the extent such
representations and warranties relate to such Placement Agent.

 

5.1.2 Each
of the Sellers, the Purchasers, the Issuer and the Company is irrevocably authorized to produce this Share Purchase Agreement
or a copy hereof to any interested party in any administrative or legal proceeding or official inquiry with respect to the matters
covered hereby.

 

5.1.3 The
Sellers or the Issuer may request from each Purchaser such additional information as the Sellers or the Issuer may deem necessary
to evaluate the eligibility of such Purchaser to acquire such Shares, and such Purchaser shall promptly provide such information
as may be reasonably requested, to the extent within Purchaser’s possession and control and consistent with internal policies
and procedure; provided, that, Sellers and Issuer agree to keep any such information provided by Purchaser confidential except
as required by law.

 

5.1.4 Each
party shall pay all of its own expenses in connection with this Share Purchase Agreement and the transactions contemplated herein.

 

5.1.5 Each
Purchaser, each Seller and the Issuer shall take, or cause to be taken, all actions and do, or cause to be done, all things necessary,
proper or advisable to consummate the transactions contemplated by this Share Purchase Agreement on the terms and conditions described
therein no later than immediately following the consummation of the Merger.

 

    16

     

    

 

5.1.6 Each
Purchaser hereby acknowledges and agrees that it will not, nor will any person acting at such Purchaser’s direction or pursuant
to any understanding with such Purchaser (including such Purchaser’s controlled affiliates), directly or indirectly, offer,
sell, pledge, contract to sell, sell any option in, or engage in hedging activities or execute any “short sales” (as
defined in Rule 200 of Regulation SHO under the Exchange Act) with respect to, any Shares or any securities of the Company or
any instrument exchangeable for or convertible into any Shares or any securities of the Company until the consummation of the
Merger (or such earlier termination of this Share Purchase Agreement in accordance with its terms). Notwithstanding the foregoing,
(i) nothing herein shall prohibit any entities under common management with the Purchaser that have no knowledge of this Share
Purchase Agreement or of the Purchaser’s participation in the transactions contemplated hereby (including the Purchaser’s
controlled affiliates and/or affiliates) from entering into any short sales; and (ii) in the case of a Purchaser that is a multi-managed
investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio
managers have no knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s
assets, this Section 5.1.6 shall only apply with respect to the portion of assets managed by the portfolio manager that made the
investment decision to purchase the Shares covered by this Share Purchase Agreement.

 

5.1.7 The
Issuer acknowledges and agrees that, notwithstanding anything herein to the contrary, the Shares may be pledged by each Purchaser
in connection with a bona fide margin agreement, provided such pledge shall be (i) pursuant to an available exemption from the
registration requirements of the Securities Act or (ii) pursuant to, and in accordance with, a registration statement that is
effective under the Securities Act at the time of such pledge, and such Purchaser effecting a pledge of Shares shall not be required
to provide Issuer with any notice thereof; provided, however, that neither Issuer or their counsel shall be required to take any
action (or refrain from taking any action) in connection with any such pledge, other than providing any such lender of such margin
agreement with an acknowledgment that the Shares are not subject to any contractual prohibition on pledging or lock up, the form
of such acknowledgment to be subject to review and comment by Issuer in all respects.

 

5.2 Notices.
Any notice or communication required or permitted hereunder shall be in writing and either delivered personally, emailed or sent
by overnight mail via a reputable overnight carrier, or sent by certified or registered mail, postage prepaid, and shall be deemed

any commitment letter entered into relating to the subject matter hereof.

 

5.4 Modifications
and Amendments. This Share Purchase Agreement may not be amended, modified, supplemented or waived except by an instrument
in writing, signed by the Issuer, on the one hand; provided, that (x) any amendment, modification, supplement or waiver of this
Share Purchase Agreement that would result in any Seller (an “Amending Seller”) receiving terms and conditions

the prior written consent of the holders of a majority of the Secondary Shares (other than the Secondary Shares held by the Amending
Seller) and (y) any amendment, modification, supplement or waiver of this Share Purchase Agreement that would result in any Purchaser
(an “Amending Purchaser”) receiving terms and conditions that are materially more advantageous than the terms
and conditions applicable to the other Purchasers signatories hereto shall require the prior written consent of the Purchasers
who will be acquiring a majority of the Ordinary Shares to be acquired under this Share Purchase Agreement (other than the Ordinary
Shares to be acquired by the Amending Purchaser), and the Seller or the Purchaser, as applicable, requesting an amendment, modification,

sought, on the other hand.

 

    19

     

    

 

5.5 Assignment.
Neither this Share Purchase Agreement nor any rights, interests or obligations that may accrue to the parties hereunder (including
each Purchaser’s rights to purchase Shares) may be transferred or assigned without the prior written consent of each of
the other parties hereto (other than such Shares acquired hereunder, if any, and then only in accordance with this Share Purchase
Agreement). Notwithstanding the foregoing, each Purchaser may assign some or all of its rights and obligations under this Share
Purchase Agreement to any fund or account managed or advised by the same investment manager or investment adviser as such Purchaser
or by an affiliate of such investment manager (which shall include any Person in which such investment manager holds 50% or more
of such Person’s voting securities) without the prior consent of the other parties hereto; provided that (x) prior to such
assignment, any such assignee shall agree in writing to be bound by the terms hereof and (y) no such assignment shall relieve
such Purchaser of its obligations hereunder.

 

5.6 Benefit.
Except as otherwise provided herein, this Share Purchase Agreement shall be binding upon, and inure to the benefit of the parties
hereto and their heirs, executors, administrators, successors, legal representatives, and permitted assigns, and the agreements,
representations, warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon,
such heirs, executors, administrators, successors, legal representatives and permitted assigns. This Share Purchase Agreement
shall not confer rights or remedies upon any person other than the parties hereto and their respective successors and assigns.

 

5.7 Governing
Law. This Share Purchase Agreement, and any claim or cause of action hereunder based upon, arising out of or related to this
Share Purchase Agreement (whether based on law, in equity, in contract, in tort or any other theory) or the negotiation, execution,
performance or enforcement of this Share Purchase Agreement, shall be governed by and construed in accordance with the Laws of
the State of Delaware, without giving effect to the principles of conflicts of law thereof.

 

5.8 Consent
to Jurisdiction; Waiver of Jury Trial. Each of the parties irrevocably consents to the exclusive jurisdiction and venue of
the Court of Chancery of the State of Delaware, provided, that if subject matter jurisdiction over the matter that is the subject
of the legal proceeding is vested exclusively in the U.S. federal courts, such legal proceeding shall be heard in the U.S. District
Court for the District of Delaware (together with the Court of Chancery of the State of Delaware, the “Chosen Courts”),
in connection with any matter based upon or arising out of this Share Purchase Agreement. Each party hereby waives, and shall
not assert as a defense in any legal dispute, that (i) such person is not personally subject to the jurisdiction of the Chosen
Courts for any reason, (ii) such legal proceeding may not be brought or is not maintainable in the Chosen Courts, (iii) such person’s
property is exempt or immune from execution, (iv) such legal proceeding is brought in an inconvenient forum or (v) the venue of
such legal proceeding is improper. Each party hereby consents to service of process in any such proceeding in any manner permitted
by Delaware law, further consents to service of process by nationally recognized overnight courier service guaranteeing overnight
delivery, or by registered or certified mail, return receipt requested, at its address specified pursuant to Section 5.2
and waives and covenants not to assert or plead any objection which they might otherwise have to such manner of service of process.
Notwithstanding the foregoing in this Section 5.8, a party may commence any action, claim, cause of action or suit in a
court other than the Chosen Courts solely for the purpose of enforcing an order or judgment issued by the Chosen Courts. TO THE
EXTENT NOT PROHIBITED BY APPLICABLE LAW WHICH CANNOT BE WAIVED, EACH OF THE PARTIES WAIVES ANY RIGHT TO TRIAL BY JURY ON ANY CLAIMS
OR COUNTERCLAIMS ASSERTED IN ANY LEGAL DISPUTE RELATING TO THIS SHARE PURCHASE AGREEMENT WHETHER NOW EXISTING OR HEREAFTER ARISING.
IF THE SUBJECT MATTER OF ANY SUCH LEGAL DISPUTE IS ONE IN WHICH THE WAIVER OF JURY TRIAL IS PROHIBITED, NO PARTY SHALL ASSERT
IN SUCH LEGAL DISPUTE A NONCOMPULSORY COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS SHARE PURCHASE AGREEMENT. FURTHERMORE, NO
PARTY SHALL SEEK TO CONSOLIDATE ANY SUCH LEGAL DISPUTE WITH A SEPARATE ACTION OR OTHER LEGAL PROCEEDING IN WHICH A JURY TRIAL
CANNOT BE WAIVED.

 

    20

     

    

 

5.9 Severability.
If any provision of this Share Purchase Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability
of the remaining provisions of this Share Purchase Agreement shall not in any way be affected or impaired thereby and shall continue
in full force and effect.

 

5.10 No
Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in exercising any right, power or remedy under
this Share Purchase Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right,
power or remedy of such party. No single or partial exercise of any right, power or remedy under this Share Purchase Agreement
by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such
party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of
any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice
to or demand on a party not expressly required under this Share Purchase Agreement shall entitle the party receiving such notice
or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the
party giving such notice or demand to any other or further action in any circumstances without such notice or demand.

 

5.11 Remedies.

 

5.11.1 The
parties agree that irreparable damage would occur if this Share Purchase Agreement was not performed or the Closing is not consummated
in accordance with its specific terms or was otherwise breached and that money damages or other legal remedies would not be an
adequate remedy for any such damage. It is accordingly agreed that the parties hereto shall be entitled to equitable relief, including
in the form of an injunction or injunctions, to prevent breaches or threatened breaches of this Share Purchase Agreement and to
enforce specifically the terms and provisions of this Share Purchase Agreement in an appropriate court of competent jurisdiction
as set forth in Section 5.8, this being in addition to any other remedy to which any party is entitled at law or in equity,
including money damages.  The right to specific enforcement shall include the right of the Sellers or the Issuer, on one
hand, to cause each Purchaser, and the Purchasers, on the other hand, to cause the Sellers and the Issuer, to cause the transactions
contemplated hereby to be consummated on the terms and subject to the conditions and limitations set forth in this Share Purchase
Agreement. The parties hereto further agree (i) to waive any requirement for the security or posting of any bond in connection
with any such equitable remedy, (ii) not to assert that a remedy of specific enforcement pursuant to this Section 5.11
is unenforceable, invalid, contrary to applicable law or inequitable for any reason and (iii) to waive any defenses in any action
for specific performance, including the defense that a remedy at law would be adequate. 

 

    21

     

    

 

5.11.2 The
parties acknowledge and agree that this Section 5.11 is an integral part of the transactions contemplated hereby and without
that right, the parties hereto would not have entered into this Share Purchase Agreement.

 

5.12 Survival
of Representations and Warranties. All representations and warranties made by each of the parties hereto in this Share Purchase
Agreement shall survive the Closing. For the avoidance of doubt, if for any reason the Closing does not occur immediately following
the consummation of the Merger, all representations, warranties, covenants and agreements of the parties hereunder shall survive
the consummation of the Merger and remain in full force and effect.

 

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

 

5.14 Counterparts.
This Share Purchase 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
parties, it being understood that the 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.

 

5.15 Construction.
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 Share Purchase Agreement,” “herein,” “hereof,”
“hereby,” “hereunder,” and words of similar import refer to this Share Purchase 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.
All references in this Share Purchase Agreement to numbers of shares, per share amounts and purchase prices shall be appropriately
adjusted to reflect any stock split, stock dividend, stock combination, recapitalization or the like occurring after the date
hereof (it being understood that the number of Shares and Purchase Price per Share set forth in this Share Purchase Agreement
assumes that the Issuer has effected the Forward Stock Split prior to the Effective Time in order to cause the value of each Ordinary
Share to equal $10.00, and no further adjustment shall be required on account of such Forward Stock Split).

 

    22

     

    

 

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

 

6. Cleansing
Statement; Consent to Disclosure.

 

6.1 The
Company shall, by 9:00 a.m., New York City time, on the first (1st) Business Day immediately following the date of this Share
Purchase Agreement, issue one (1) or more press releases or file with the Commission a Current Report on Form 8-K (collectively,
the “Disclosure Document”) disclosing all material terms of the transactions contemplated hereby and by the
Employee Share Purchase Agreement, and the Transactions. From and after the publication of the Disclosure Document, the Purchaser
shall not be in possession of any material, nonpublic information received from the Company or any of its officers, directors,
employees or agents in connection with the transactions contemplated by this Share Purchase Agreement and the Transactions, and
Purchaser shall no longer be subject to any confidentiality or similar obligations under any current agreement, whether written
or oral with the Issuer, the Placement Agents, or any of their affiliates in connection with the Transactions; provided, that
the foregoing shall not apply to the Sponsors.

 

6.2 Each
Purchaser hereby consents to the disclosure in the Form 8-K filed by the Company with the SEC in connection with the execution
and delivery of the Merger Agreement and the Proxy Statement (and, as and to the extent otherwise required by the federal securities
laws or the SEC or any other securities authorities, any other documents or communications provided by the Issuer or the Company
to any governmental authority or to securityholders of the Issuer or the Company) of such Purchaser’s identity and beneficial
ownership of its Shares and the nature of such Purchaser’s commitments, arrangements and understandings under and relating
to this Share Purchase Agreement and, if deemed appropriate by the Issuer or the Company, a copy of this Share Purchase Agreement;
provided that, in the case of such disclosures by the Issuer or the Company, the Issuer or Company, as applicable, shall provide
each Purchaser with prior written notice (including by e-mail) of such permitted disclosure, and shall reasonably consult with
such Purchaser regarding such disclosure, in each case, to the extent such disclosure specifically names such Purchaser. Other
than in the Registration Statement contemplated by the Secondary Side Letter, as required by any laws, rules or regulations (including,
without limitation, securities laws, rules or regulations), at the request of the staff of the Commission or any regulatory agency
or as set forth in the immediately preceding sentence, without Purchaser’s prior written consent (including by email), neither
the Issuer nor the Company shall, and shall cause their respective officers, directors, affiliates, and agents (including the
Placements Agents) not to, publicly disclose the name of any Purchaser or any of its affiliates or investment advisers (i) in
any press release or marketing materials or (ii) in any filing with the Commission or any regulatory agency or trading market
other than as set forth above, except to the Sellers’ and the Issuer’s securityholders, lawyers, independent accountants
and other advisors and service providers who reasonably require such information in connection with the provision of services
to such person, are advised of the confidential nature of such information and are obligated to keep such information confidential.
Each Purchaser will promptly provide any information reasonably requested by the Issuer or the Company for any regulatory application
or filing made or approval sought in connection with the Transactions (including filings with the SEC).

 

    23

     

    

 

7. Trust
Account Waiver. Notwithstanding anything to the contrary set forth herein, each Purchaser and each Seller acknowledges that
it has read the Investment Management Trust Agreement, dated as of October 1, 2020, by and between the Company and Continental
Stock Transfer & Trust Company, a New York corporation, and understands that the Company has established the trust account
described therein (the “Trust Account”) for the benefit of the Company’s public shareholders and that
disbursements from the Trust Account are available only in the limited circumstances set forth therein. Each Purchaser and each
Seller further acknowledges and agrees that the Company’s sole assets consist of the cash proceeds of the Company’s
initial public offering and private placements of its securities, and that substantially all of these proceeds have been deposited
in the Trust Account for the benefit of its public shareholders. Accordingly, each Purchaser and each Seller (on behalf of itself
and its affiliates) hereby waives any past, present or future claim of any kind against, and any right to access, the Trust Account,
any trustee of the Trust Account and the Company to collect from the Trust Account any monies that may be owed to them by the
Company or any of its affiliates for any reason whatsoever, and will not seek recourse against the Trust Account at any time for
any reason whatsoever, including for any knowing and intentional material breach by any of the parties to this Share Purchase
Agreement of any of its representations or warranties as set forth in this Share Purchase Agreement, or such party’s material
breach of any of its covenants or other agreements set forth in this Share Purchase Agreement, which material breach constitutes,
or is a consequence of, a purposeful act or failure to act by such party with the knowledge that the taking of such act or failure
to take such act would cause a material breach of this Share Purchase Agreement; provided, however, that nothing in this Section
7 shall be deemed to limit any Purchaser’s or any Seller’s right, title, interest, or claim to the Trust Account by
virtue of such Person’s record or beneficial ownership of securities of the Company acquired by any means, other than pursuant
to this Share Purchase Agreement, including any redemption right with respect to any such securities of the Company. In the event
any Purchaser or any Seller has any Claim against the Company under this Share Purchase Agreement, such Person shall pursue such
Claim solely against the Company and its assets outside the Trust Account and not against the property or any monies in the Trust
Account. This Section 7 shall survive the termination of this Share Purchase Agreement for any reason.

 

8. Rule
144. From and after such time as the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or
regulation of the Commission that may allow any Purchaser to sell its Shares to the public without registration are available
to holders of the Issuer’s Ordinary Shares and until the third (3rd) anniversary of the Closing Date, the Issuer shall,
at its expense:

 

8.1 make
and keep public information available, as those terms are understood and defined in Rule 144;

 

8.2 use
commercially reasonable efforts to file with the Commission in a timely manner all reports and other documents required of the
Issuer under the Securities Act and the Exchange Act so long as the Issuer remains subject to such requirements and the filing
of such reports and other documents is required for the applicable provisions of Rule 144 to enable each Purchaser to sell its
Shares under Rule 144 for so long as such Purchaser holds any Shares;

 

    24

     

    

 

8.3 furnish
to each Purchaser, promptly upon such Purchaser’s reasonable request, (i) a written statement by the Issuer, if true, that
it has complied with the reporting requirements of Rule 144, the Securities Act, and the Exchange Act, (ii) a copy of the most
recent annual or quarterly report of the Issuer and such other reports and documents so filed by the Issuer, and (iii) such other
information as may be reasonably requested to permit such Purchaser to sell such securities pursuant to Rule 144 without registration;
and

 

8.4 If
in the opinion of counsel to the Issuer, it is then permissible to remove the restrictive legend from the Shares pursuant to Rule
144 under the Securities Act, then at a Purchaser’s request, the Issuer will request its transfer agent to remove the legend
set forth in Section 2.1.5.

 

8.5 The
obligations of each Purchaser under this Share Purchase Agreement are several and not joint with the obligations of any other
Purchaser, Other Purchaser or any other investor under the Employee Share Purchase Agreement, and no Purchaser shall be responsible
in any way for the performance of the obligations of any other Purchaser, Other Purchaser or any other investor under the Employee
Share Purchase Agreement, or the Issuer under the Merger Agreement. The decision of each Purchaser to purchase Shares pursuant
to this Share Purchase Agreement has been made by such Purchaser independently of any other Purchaser, Other Purchaser or any
other investor and independently of any information, materials, statements or opinions as to the business, affairs, operations,
assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Issuer, the Company
or any of their respective subsidiaries which may have been made or given by any other Purchaser, Other Purchaser or investor
or by any agent or employee of any other Purchaser, Other Purchaser or investor, and neither such Purchaser nor any of its agents
or employees shall have any liability to any other Purchaser, Other Purchaser or investor (or any other Person) relating to or
arising from any such information, materials, statements or opinions. Nothing contained herein, in any Employee Share Purchase
Agreement or in the Merger Agreement, and no action taken by any Purchaser, any investor or the Issuer hereunder or thereunder,
shall be deemed to constitute any Purchaser, the other investors or the Issuer as a partnership, an association, a joint venture
or any other kind of entity, or create a presumption that any Purchaser, the other investors or the Issuer are in any way acting
in concert or as a group with respect to such obligations or the transactions contemplated by this Share Purchase Agreement, the
Employee Share Purchase Agreement or the Merger Agreement. Each Purchaser shall be entitled to independently protect and enforce
its rights, including without limitation the rights arising out of this Share Purchase Agreement, and it shall not be necessary
for any other Purchaser, Other Purchaser or investor to be joined as an additional party in any proceeding for such purpose.

Execution Version

 

SIDE LETTER

 

This SIDE LETTER (this
“Side Letter”) is entered into this 25th day of January, 2021, by and among the purchasers who have executed
a signature page hereto (collectively, the “Purchasers” and each, individually, a “Purchaser”)
and Taboola.com Ltd., a company organized under the laws of the State of Israel (the “Issuer”).

 

WHEREAS, the undersigned
are parties to a Share Purchase Agreement, dated as of the date hereof (each, a “Share Purchase Agreement” and,
collectively, the “Share Purchase Agreements”), pursuant to which the Purchasers desire to purchase ordinary
shares of the Issuer of no par value (the “Ordinary Shares”) subject to the terms and conditions thereof and
in connection with the transactions contemplated by that certain Agreement and Plan of Merger, dated as of the date hereof, by
and among the Issuer, Toronto Sub Ltd., a Cayman Islands exempted company and wholly owned subsidiary of the Issuer, and ION Acquisition
Corp. 1 Ltd., a Cayman Islands exempted company (the “Transactions”); and

 

WHEREAS, the Purchasers
wish to receive, and the Issuer wishes to provide, certain registration rights with respect to the Ordinary Shares to be acquired
by the Purchasers pursuant to the Share Purchase Agreements.

 

NOW, THEREFORE, in
consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, herein
contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

 

1. Registration
Statement.

 

1.1 The
Issuer agrees that, within thirty (30) calendar days after the closing of the Transactions (the “Filing Date”),
the Issuer will file with the Securities and Exchange Commission (“Commission”) (at the Issuer’s sole
cost and expense) a registration statement registering the resale of the Ordinary Shares to be sold to the Purchasers under the
Share Purchase Agreements and any Ordinary Shares sold to other purchasers pursuant to other private placements by the Issuer in
connection with the Transactions (the “Registration Statement”), and the Issuer shall use its commercially reasonable
efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but no later than
the earlier of (i) the 60th calendar day (or 90th calendar day if the Commission notifies the Issuer that
it will “review” the Registration Statement) following the closing of the Transactions and (ii) the 10th Business Day
after the date the Issuer is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement
will not be “reviewed” or will not be subject to further review (such earlier date, the “Effectiveness Date”);
provided, however, that the Issuer’s obligations to include the Ordinary Shares of each Purchaser in the Registration
Statement are contingent upon each such Purchaser furnishing in writing to the Issuer such information regarding such Purchaser,
the securities of the Issuer held by such Purchaser and the intended method of disposition of such Ordinary Shares as shall be
reasonably requested by the Issuer to effect the registration of such Purchaser’s Ordinary Shares, and each such Purchaser
shall execute such documents in connection with such registration as the Issuer may reasonably request that are customary of a
selling shareholder in similar situations, including providing that the Issuer shall be entitled to postpone and suspend the effectiveness
or use of the Registration Statement during any customary blackout or similar period or as permitted hereunder. For purposes of
clarification, any failure by the Issuer to file the Registration Statement by the Filing Date or to effect such Registration Statement
by the Effectiveness Date shall not otherwise relieve the Issuer of its obligations to file or effect the Registration Statement
as set forth above in this Section 1.1.

 

     

     

    

 

1.2 The
Issuer shall, upon reasonable request, inform each Purchaser as to the status of the registration effected by the Issuer pursuant
to this Side Letter. At its expense the Issuer shall:

 

1.2.1 except
for such times as the Issuer is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement,
use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities
laws which the Issuer determines to obtain, continuously effective with respect to the Purchasers, and to keep the applicable Registration
Statement or any subsequent shelf registration statement free of any material misstatements or omissions, until the earlier of
the following: (i) the Purchasers cease to hold any Ordinary Shares, (ii) the date all Ordinary Shares held by the Purchasers may
be sold without restriction under Rule 144, including any volume and manner of sale restrictions under Rule 144 and without the
requirement for the Issuer to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2),
if applicable), and (iii) three (3) years from the Effectiveness Date of the Registration Statement;

 

1.2.2 advise
each Purchaser as expeditiously as possible, but in any event within five (5) Business Days:

 

(a) when
the Registration Statement or any post-effective amendment thereto has become effective;

 

(b) of
the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation of
any proceedings for such purpose; and

 

(c) of
the receipt by the Issuer of any notification with respect to the suspension of the qualification of the Ordinary Shares included
therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose.

 

Notwithstanding
anything to the contrary set forth herein, the Issuer shall not, when so advising a Purchaser of such events, provide such Purchaser
with any material, nonpublic information regarding the Issuer other than to the extent that providing notice to such Purchaser
of the occurrence of the events listed in (a) through (c) above constitutes material, nonpublic information regarding the Issuer;

 

1.2.3 use
its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of the Registration Statement
as soon as reasonably practicable;

 

    2

     

    

 

1.2.4 upon
the occurrence of any event that requires the making of any changes in the Registration Statement or prospectus so that, as of
such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or
necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made)
not misleading, except for such times as the Issuer is permitted hereunder to suspend, and has suspended, the use of a prospectus
forming part of the Registration Statement, the Issuer shall use its commercially reasonable efforts to as soon as reasonably practicable
prepare a post-effective amendment to the Registration Statement or a supplement to the related prospectus, or file any other required
document so that, as thereafter delivered to purchasers of the Ordinary Shares included therein, such prospectus will not include
any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading; and

 

1.2.5 use
its commercially reasonable efforts to cause all Ordinary Shares to be listed on each securities exchange or market, if any, on
which the Issuer’s Ordinary Shares are then listed.

 

1.2.6 Notwithstanding
anything to the contrary in this Share Purchase Agreement, the Issuer shall not have any obligation to prepare any prospectus supplement,
participate in any due diligence, execute any agreements or certificates or deliver legal opinions (other than customary de-legending
certificates and opinions) or obtain comfort letters in connection with any sales of the Ordinary Shares under the Registration
Statement.

 

1.3 Notwithstanding
anything to the contrary in this Share Purchase Agreement, the Issuer shall be entitled to delay or postpone the effectiveness
of the Registration Statement, and from time to time to require the Purchasers not to sell under the Registration Statement or
to suspend the effectiveness thereof, if the negotiation or consummation of a transaction by the Issuer or its subsidiaries is
pending or an event has occurred, which negotiation, consummation or event the Issuer’s board of directors reasonably believes,
upon the advice of legal counsel (which may be in-house legal counsel), would require additional disclosure by the Issuer in the
Registration Statement of material information that the Issuer has a bona fide business purpose for keeping confidential and the
non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of the Issuer’s
board of directors, upon the advice of legal counsel (which may be in-house legal counsel), to cause the Registration Statement
to fail to comply with applicable disclosure requirements (each such circumstance, a “Suspension Event”); provided,
however, that the Issuer may not delay or suspend the Registration Statement on more than three (3) occasions or for more
than sixty (60) consecutive calendar days, or more than one hundred and twenty (120) total calendar days, in each case during any
twelve (12)-month period. Upon receipt of any written notice from the Issuer of the happening of any Suspension Event during the
period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related
prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus)
not misleading, each Purchaser agrees that (i) it will immediately discontinue offers and sales of its Ordinary Shares under the
Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until such Purchaser receives
copies of a supplemental or amended prospectus (which the Issuer agrees to promptly prepare) that corrects the misstatement(s)
or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise
notified by the Issuer that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information
included in such written notice delivered by the Issuer unless otherwise required by law or subpoena. If so directed by the Issuer,
each Purchaser will deliver to the Issuer or, in such Purchaser’s sole discretion destroy, all copies of the prospectus covering
the Ordinary Shares in such Purchaser’s possession; provided, however, that this obligation to deliver or destroy
all copies of the prospectus covering the Ordinary Shares shall not apply (i) to the extent such Purchaser is required to retain
a copy of such prospectus (a) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements
or (b) in accordance with a bona fide pre-existing document retention policy or (ii) to copies stored electronically on archival
servers as a result of automatic data back-up.

1.4 The
Issuer shall, notwithstanding any termination of this Side Letter or the Share Purchase Agreement, indemnify, defend and hold harmless
each Purchaser (to the extent a seller under the Registration Statement), the officers, directors, agents, partners, members, managers,
shareholders, affiliates, employees and investment advisers of each Purchaser, each person who controls such Purchaser (within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act), and the officers, directors, partners, members,
managers, shareholders, agents, affiliates, employees and investment advisers of each such controlling person, to the fullest extent
permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation,
reasonable costs of preparation and investigation and reasonable attorneys’ fees) and expenses (collectively, “Losses”),
as incurred, that arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained in the
Registration Statement, any prospectus included in the Registration Statement or any form of prospectus or in any amendment or
supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state
a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form
of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, or (ii) any violation
or alleged violation by the Issuer of the Securities Act, the Exchange Act or any state securities law or any rule or regulation
thereunder, in connection with the performance of its obligations under this Side Letter, except to the extent, but only to the
extent, that such untrue statements, alleged untrue statements, omissions or alleged omissions are based solely upon information
regarding such Purchaser furnished in writing to the Issuer by such Purchaser expressly for use therein.

 

The Issuer shall notify
each Purchaser promptly of the institution, threat or assertion of any proceeding arising from or in connection with the transactions
contemplated by this Side Letter and the Share Purchase Agreement of which the Issuer is aware. The indemnity under this Section
1.4 shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and
shall survive the transfer of the Shares by any Purchaser.

 

1.5 Each
Purchaser shall, severally and not jointly with any other selling shareholder named in the Registration Statement, indemnify and
hold harmless the Issuer, its directors, officers, agents and employees, each person who controls the Issuer (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such
controlling persons, to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of
or that are based upon any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any prospectus
included in the Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary
prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein
or necessary to make the statements therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in
light of the circumstances under which they were made) not misleading to the extent, but only to the extent, that such untrue statements
or omissions are based solely upon information regarding such Purchaser furnished in writing to the Issuer by such Purchaser expressly
for use therein. In no event shall the liability of any Purchaser be greater in amount than the dollar amount of the net proceeds
received by such Purchaser upon the sale of the Ordinary Shares giving rise to such indemnification obligation.

 

2. Miscellaneous.
The provisions of Sections 4 (Termination), 5 (Miscellaneous), 6 (Consent to Disclosure)
and 7 (Trust Account Waiver) of the applicable Share Purchase Agreement to which the Issuer and the applicable Purchaser
is party shall apply to this Side Letter as if set forth herein, mutatis mutandis.
