The issuance of the New Parent Ordinary Shares hereunder shall be to DTC as nominee, in which case the transfer of legal title to the New Parent Ordinary Shares to the holders of Shares (other than Excluded Shares) shall be conditional only upon (i) U.S. Holdco having transferred all of its shares of Lux Finco 2 to New Parent (which US Holdco undertakes to do prior to satisfaction of the condition in Section 6.1(b)) and (ii) compliance by those holders with Section 4.4. In addition, New Parent or U.S. Holdco shall deposit, or cause to be deposited, with the Exchange Agent, as necessary from time to time from and after the Effective Time, any dividends or other distributions payable pursuant to Section 4.6 with respect to the New Parent Ordinary Shares with a record and payment date prior to the surrender of such Shares (such New Parent Ordinary Shares, together with the amount of any dividends or other distributions payable with respect thereto, being hereinafter referred to as the “Exchange Fund”).

Section 4.4 Certificated Shares. Promptly after the Effective Time, the Surviving Corporation shall cause the Exchange Agent to mail to each holder of record of a Certificate, (a) a letter of transmittal (which shall notify holders of the effectiveness of the Merger and specify that delivery shall be effected, and that risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates (or affidavit of loss in lieu thereof as provided in Section 4.9) to the Exchange Agent), and (b) instructions for effecting the surrender of the Certificates (or affidavit of loss in lieu thereof as provided in Section 4.9) to the Exchange Agent in exchange for delivery of the Merger Consideration therefor.

4

the holder of such Certificates shall be entitled to receive in exchange therefor: (x) New Parent Ordinary Shares in non-certificated book-entry form representing the New Parent Ordinary Shares into which the Shares represented by such holder’s Certificates were converted pursuant to Section 4.2, and the Certificates so surrendered shall forthwith be cancelled, and (y) a check in an amount of United States dollars equal to any cash dividends or other distributions that such holder has the right to receive pursuant to Section 4.6 less any applicable withholding Taxes as provided in Section 4.10 and without interest thereon.

Section 4.5 Uncertificated Shares.

Section 4.6 Dividends and Distributions with Respect to Unexchanged Shares; Voting.

(a) All New Parent Ordinary Shares to be issued pursuant to the Merger shall be issued and outstanding as of the Effective Time and whenever a dividend or other distribution is declared by New Parent in respect of the New Parent Ordinary Shares, the record date for which is after the Effective Time, that declaration shall include dividends or other distributions in respect of all New Parent Ordinary Shares issued in the Merger. The Exchange Agent shall hold any New Parent Ordinary Shares in respect of unsurrendered Certificates in trust for the holder of such Certificate until such Certificate (or affidavit of loss in lieu thereof as provided in Section 4.8) has been surrendered for exchange in accordance with this Article IV. No dividends or other distributions in respect of the New Parent Ordinary Shares shall be paid to any holder of any unsurrendered Certificate until such Certificate (or affidavit of loss in lieu thereof as provided in Section 4.8) has been surrendered for exchange in accordance with this Article IV. Subject to applicable Law and the provisions of this Article IV, following surrender of any such Certificate (or affidavit of loss in lieu thereof as provided in Section 4.8), there shall be delivered to the record holder of the certificates representing shares of New Parent Ordinary Shares in exchange therefor, and, after deduction for any applicable withholding Taxes as provided in Section 4.10 and without interest thereon, (i) at the time of such surrender, the dividends or other distributions with a record date after the Effective Time with respect to such New Parent Ordinary Shares and not theretofore paid and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such New Parent Ordinary Shares with a record date after the Effective Time, but with a payment date subsequent to such surrender.

(b) Registered holders of unsurrendered Certificates shall be entitled to direct the Exchange Agent how to vote the number of New Parent Ordinary Shares represented by such unsurrendered Certificates at any meeting of New Parent shareholders with a record date at or after the Effective Time, regardless of whether such holders have exchanged their Certificates.

Any holder of Certificates (as applicable) who has not theretofore complied with this Article IV prior to the one year anniversary of the Effective Time shall thereafter look only to New Parent for delivery of New Parent Ordinary Shares and payment of any dividends and other distributions in respect thereof, in each case, less any applicable withholding Taxes as provided in Section 4.10 and without any interest thereon. Notwithstanding the foregoing, none of the Surviving Corporation, New Parent, the Exchange Agent or any other Person shall be liable to any former holder of Shares for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws.

Section 4.9 Transferred Certificates; Lost, Stolen or Destroyed Certificates. In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and compliance with the replacement requirements established by the Exchange Agent including, if required by the Exchange Agent, the posting by such Person of a bond in customary amount and upon such terms as may be required by New Parent as indemnity against any claim with respect to such Certificate that may be made against it, the Exchange Agent or the Surviving Corporation, the Exchange Agent shall deliver to such Person (or its designee) in exchange for such lost, stolen or destroyed Certificate, the New Parent Ordinary Shares and any dividends and other distributions in respect of the New Parent Ordinary Shares that would have been delivered pursuant to the provisions of this Article IV had such lost, stolen or destroyed Certificate been surrendered. If delivery of the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition of delivery that the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and that the Person requesting such delivery shall have paid to the Exchange Agent any transfer and other Taxes required by reason of the delivery of the Merger Consideration to a Person other than the record holder of the Certificate surrendered or shall have established to the satisfaction of the Exchange Agent that such Tax either has been paid or is not applicable.

Section 4.10 Withholding Rights. Each of New Parent, U.S. Holdco, Merger Sub, the Surviving Corporation and the Exchange Agent, as applicable, shall be entitled to deduct and withhold from any consideration or amount otherwise payable pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under any applicable Tax Law. To the extent that amounts are so withheld by New Parent, U.S. Holdco, Merger Sub, the Surviving Corporation or the Exchange Agent, as the case may be, such withheld amounts (a) shall be remitted to the applicable Governmental Entity and (b) shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made. To the extent that the amount so required to be deducted or withheld under applicable Tax Law from the payment of any consideration

6

otherwise payable to any Person pursuant to this Agreement exceeds the cash consideration otherwise payable to such Person pursuant to this Agreement, each of New Parent, U.S. Holdco, Merger Sub, the Surviving Corporation and the Exchange Agent, as applicable, is hereby authorized to sell such portion of the New Parent Ordinary Shares or other non-cash consideration otherwise payable to such Person as is necessary to provide sufficient funds to enable it to comply with such deduction and withholding requirement.
