AGREEMENT

 

NOW, THEREFORE, for
and in consideration of the mutual covenants and agreements set forth herein, and other good and valuable consideration, the receipt
and sufficiency of which is hereby acknowledged, the parties, intending to be legally bound, agree as follows:

 

1.          Representations
and Warranties. Each of the parties hereto, by their respective execution and delivery of this Agreement, hereby represents
and warrants to the others and to all third party beneficiaries of this Agreement that (a) such party has the full right, capacity
and authority to enter into, deliver and perform its respective obligations under this Agreement, (b) this Agreement has been duly
executed and delivered by such party and is the binding and enforceable obligation of such party, enforceable against such party

under this Agreement will not conflict with or breach the terms of any other agreement, contract, commitment or understanding to
which such party is a party or to which the assets or securities of such party are bound.

 

    	 

    	 

    

 

Each Holder has independently
evaluated the merits of its decision to enter into and deliver this Agreement, and such Holder confirms that it has not relied
on the advice of the Company, the Company’s counsel, Holder, Holder’s counsel, or any other person.

 

2.          Beneficial
Ownership. Each Holder hereby represents and warrants that it does not beneficially own, directly or through its nominees (as
determined in accordance with Section 13(d) of the Exchange Act of 1934, as amended (the “Exchange Act”),
and the rules and regulations promulgated thereunder) any shares of Company common stock, or any economic interest therein or derivative
therefrom, other than those Company ordinary shares the aggregate counter value of which is specified on the signature page hereto
(the “Agreement Shares”).

 

3.          Sale
of Agreement Shares.

 

(a)          During
the Sale Limitation Period (as defined below), the Holders irrevocably agrees that they will not (i) sell, directly or indirectly,
more than USD 870,000 of Agreement Shares in public market transactions in any calendar month (the “Monthly Target”),
except as provided in Section 3(h) hereof, (ii) publicly disclose the intention to make any offer, sale, pledge or disposition,
or to enter into any transaction, swap, hedge or other arrangement, or engage in any Short Sales (as defined below) with respect
to any security of the Company, or (iii) sell any Agreement Shares or Make-Whole Shares (as defined below) in public market transactions
at a price per share less than the lowest third-party ask price in the market (not including an ask price posted by the Seller
or any of its agents or affiliates).

 

(b)          In
furtherance of the foregoing, the Company will (i) place an irrevocable stop order on all Agreement Shares, including those which
are covered by a registration statement, and (ii) notify its transfer agent in writing of the stop order and the restrictions on
the Agreement Shares under this Agreement and direct its transfer agent not to process any attempts by any Holder
to resell or transfer any Agreement Shares, except in compliance with this Agreement.

 

(c)          For
purposes hereof, “Short Sales” include, without limitation, all “short sales” as defined
in Rule 200 promulgated under Regulation SHO under the Exchange Act and all types of direct and indirect stock pledges, forward
sale contracts, options, puts, calls, swaps and similar arrangements (including on a total return basis), and sales and other transactions
through non-US broker dealers or foreign regulated brokers.

 

(d)          For
purpose hereof, the “Sale Limitation Period” means a period of 9 months from the Closing Date.

 

(e)          To
the extent that the Holders collectively sell all of the Agreement Shares, and the Agreement Shares that are sold in public market
transactions are sold at an average price (the “Average Sales Price”) of less than $10.00 per share,
the Holders shall be entitled to receive from the Company, promptly after the Company receives a request therefor form the Seller,
a number of additional shares (the “Make-Whole Shares”) of Parent’s Common Stock equal to (x)(1)
$10.00 minus the Average Sales Price (the “Shortfall”), multiplied by (2) the number of Agreement Shares
sold in public market transactions, divided by (y) the Fair Market Value of the Parent Common Stock. The Holders shall provide
evidence of the Average Sales Price by providing the Company with copies of sales confirmations for the Agreement Shares along
with the Holders calculations of the Average Sales Price and the Shortfall. In lieu of issuing Make-Whole Shares to the Seller,
the Company may elect to pay the amount of any Shortfall to the Holders in cash within ten (10) business days of receiving notice
of the Shortfall from the Holders.

 

    	2

    	 

    

 

(f)          To
the extent that the Holders sell all of the Make-Whole Shares, and (i) the aggregate consideration received for all Agreement Shares
and Make-Whole Shares sold by the Holders in public market transactions plus (ii) the number of Make-Whole Shares sold in non-public
transactions multiplied by the greater of the actual average sales price of such Make-Whole Shares or the average sales price of
the Agreement Shares and Make-Whole Shares sold by the Holders in public market transactions (the “Make-Whole Share
Average Sales Price”), is less than the Transaction Value (as defined below), then the Company shall, promptly after
receiving a request therefor from the Holders, issue additional Make-Whole Shares equal to (x) (i) the Transaction Value minus
(ii) the aggregate dollar amount received by the Holders for all Agreement Shares and Make-Whole Shares sold in public market transactions,
plus the product of the number of Make-Whole Shares sold by the Holders in non-public transactions multiplied by the Make-Whole
Share Average Sales Price (each a “Make-Whole Shortfall”), divided by (y) the Fair Market Value of the
Parent’s Common Stock. The Holders shall provide evidence of the aggregate consideration received for all of the Agreement
Shares and Make-Whole Shares sold by the Holders by providing the Company with copies of sales confirmations or other comparable
evidence along with the Holders’ calculations of the Make-Whole Shortfall. In lieu of issuing Make-Whole Shares to the Seller,
the Company may elect to pay the amount of any Make-Whole Shortfall to the Holders in cash within thirty business days of receiving
notice of the Make-Whole Shortfall from the Holders. The term Transaction Value means an amount which (a) is the
product of the Agreement Shares sold in public market transactions multiplied by $10.00), minus (b)(i) the aggregate amount of
any dividend payment made by Parent on any Agreement Shares and Make-Whole Shares, and (ii) the value of any payment made under
Article 10.1 of the Stock Purchase Agreements.

 

(g)          The
Holders shall cease selling any Make-Whole Shares, and the provisions of Sections 3(e) and (f) shall terminate and be of no further
force or effect, once the aggregate consideration received by the Holders for all Agreement Shares and Make-Whole Shares
sold in public market transactions, plus the product of the number of Make-Whole Shares sold by the Holders in non-public transactions
multiplied by the Make-Whole Share Average Sales Price equals or exceeds the Transaction Value, and shall so notify the Company
in writing. If, within ten business days of receiving such notification, the Company responds to the Holders Representative in
writing that it wishes to repurchase the remaining Make-Whole Shares owned by the Holders, the Company and the Holders’ Representative
shall set a mutually satisfactory date when the Make-Whole Shares may be sold back to the Company. The purchase price for all of
the remaining Make-Whole Shares shall be an aggregate of $1.00. In the event that the Holders’ Representative does not receive
such a notice from the Company within the ten business day period, the Holders may sell all remaining Agreement Shares and Make
Whole Shares and retain the profits therefrom.

 

    	3

    	 

    

 

(h)          In
the event that, in each calendar month, the Holders collectively are not able to sell the Monthly Target, the Holders will be allowed
to sell, in the following months, in addition to the Monthly Target for that month, a number of Agreement Shares equal to the balance
between the Monthly Target and the number of Agreement Shares actually sold in the previous months, provided that: (i) at the end
of each month in which the Monthly Target has not been reached, the Holders’ Representative has informed the Company in writing
pursuant to Section 8 hereof of the number and the price of the Agreement Shares actually sold in such month; and (ii) a quarterly
threshold of 33% of the Agreement Shares is not exceeded.

 

4.          Breach.

 

If
the Holder materially breaches the terms of Sections 1 through 3 of this Agreement, this Agreement shall automatically terminate
and Parent shall have no further obligations to the Holder pursuant to this Agreement.

 

5.          Company’s
Indemnification Obligations; Pledge. 

 

(a)          The
Holders have issued the guarantees attached as Annex 5 (the “Guarantees”) to guarantee the Targets’ obligations
vis-à-vis certain banks that hold mortgages on the Targets’ assets. The Company undertakes to indemnify and hold harmless
the Holders for any actual disbursement that such Holders may incur as a result of the enforcement of the Guarantees; provided,
however, that the indemnification obligation provided under this Section 5(a) will be enforceable and effective as long as the
Company holds all the issued and outstanding securities of the Targets.

 

(b)          To
secure the Company’s obligations provided under letter (a), at closing, the Company, LuxCo and the Holders will enter into
a pledge agreement pursuant to which the Company and LuxCo will pledge their participation in Targets to the benefit of Holders
during the Sale Limitation Period.

 

6.          Escrow
of Units; Call Option.

 

(a)          The
Units shall be deposited in an escrow within 30 calendar days from the Closing Date (the “Escrow Fund”) with
a financial institution mutually satisfactory to the Parent and the Holders, as escrow agent (the “Escrow Agent”),
to be held in accordance with the terms set forth in this Agreement and the Escrow Agreement that the Parties undertake to
negotiate and agree upon immediately after Closing (the “Escrow Agreement”).

 

(b)          In
the event that (i) in selling the Agreement Shares, the Holders cannot sell a sufficient number of Agreement Shares and Make-Whole
Shares to reach one of the dollar targets set out in Annex 6 hereto, or (ii) the SEC has informed the Company that the registration
statement may not go effective, then the Holders shall have an option (the “Call Option”) to repurchase the
entire equity interest in Targets held by the Company (the “Repurchased Participation”).

 

    	4

    	 

    

 

(c)          In
order to exercise the Call Option, the Holders must (i) comply with the terms and conditions set forth in the Escrow Agreement,
and (ii) within 5 business days from the end of any period set out in Annex 6 hereto or the date the Company notifies the Holder
that the Registration Statement will not go effective, provide the Escrow Agent with a repurchase notice confirming either that
the Target Dollar Value of Shares To Be Sold has not been reached and the amount that the Agreement Shares and Make-Whole Shares
have been sold for, including satisfactory documentation as to the sale price of the Agreement Shares and Make-Whole Shares or
that the SEC has informed the Company that the registration statement may not go effective (the “Repurchase Notice”).
Upon receipt of the Repurchase Notice, the Escrow Agent shall deliver a copy of the Repurchase Notice to the Company. If the Company
does not object to the Repurchase Notice within 7 business days of the date of receipt of the Repurchase Notice, then the Escrow
Agent shall proceed to the closing of the Repurchased Participation according to the terms and conditions of the Escrow Agreement.

 

(d)          In
accordance with the terms of the Escrow Agreement, the closing of any purchase and sale of the Repurchased Participation shall
take place no later than thirty (30) business days following receipt by the Company of the Repurchase Notice.

 

(e)          In
the event that any bankruptcy, insolvency, receivership, liquidation or other similar proceedings is commenced by or against Parent
or LuxCo, or a trustee, receiver, liquidator, or custodian is appointed for Parent or LuxCo, or Parent or LuxCo make a general
assignment for the benefit of creditors, the Holders’ Representative may direct the Escrow Agent to transfer the Escrow Units
to Holders’ Representative in exchange for the Option Consideration (as defined below). Upon receipt of such an instruction
from the Holders’, the Escrow Agent shall advise Parent and LuxCo of such instruction, and, no earlier than 5 business days
after notifying Parent and LuxCo, without any further action by LuxCo or Parent, transfer the Escrow Units to Holders’ Representative
in exchange for the Option Consideration.

 

(f)          At
the closing of the transactions pursuant to this Section 6, the Escrow Agent, (i) shall deliver to a notary public indicated by
Holders’ Representative the irrevocable Power of Attorney delivered to Escrow Agent pursuant to the Escrow Agreement to effect
the transfer of the Repurchased Participation in the corporate books of the Targets, and (ii) shall transfer to the Company (x)
the entire amount the Holders have received by the sale of the Agreement Shares and Make Whole Shares in public market or private
transactions, if any, less (i) the Tax Franchise Amount, (ii) the transaction costs demonstrably incurred by Holders in selling
the Agreement Shares, (iii) the Escrow Agent costs, and (y) any remaining Agreement Shares or Make-Whole Shares held by the Holders
(the “Option Consideration”).

 

(g)          Provided
effectiveness of the registration statement, notwithstanding anything in this Section 6 to the contrary, the Call Option may not
be exercised for an applicable period in the event that the dollar amount of all shares traded for such period is equal to or in
excess of the Target Dollar Value of Shares To Be Sold for such period.
