In addition, the Company shall deliver to each Holder of Cashed-out Options and Cashed-out RSUs, forthwith after the Effective Time, a cheque issued by the Company (or other form of immediately available funds) representing that amount of cash which such Holder of Cashed-out Options and Cashed-out RSUs has the right to receive, less any amounts withheld pursuant to Section 4.5.

Until surrendered as contemplated by this Section 4.1, each certificate of Shares (excluding Rollover Shares) shall be deemed at all times after the Effective Time to represent only the right to receive upon such surrender a cash payment in the manner contemplated by this Section 4.1, less any amounts withheld pursuant to Section 4.5. The provisions contained in the Rollover Agreement prevail over this Section 4.1 with respect to the securities of the Company subject to such Rollover Agreement.

No dividends or other distributions declared or made after the Effective Time with respect to Shares with a record date after the Effective Time shall be paid to the Holder of any unsurrendered certificate which immediately prior to the Effective Time represented outstanding Shares that were transferred pursuant to Section 3.1.

In the event any certificate which immediately prior to the Effective Time represented one or more outstanding Shares that were transferred pursuant to Section 3.1 is 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, the Depositary will issue in exchange for such lost, stolen or destroyed certificate, a cheque (or other form of immediately available funds) for the cash amount, deliverable in accordance with such Holder’s Letter of Transmittal. When authorizing such payment in exchange for any lost, stolen or destroyed certificate, the Person to whom cash is to be delivered shall, as a condition precedent to the payment thereof, give a bond satisfactory to Parent and the Company and their respective transfer agents in such sum as Parent and the Company may direct or otherwise indemnify Parent and the Company in a manner satisfactory to Parent and the Company against any claim that may be made against Parent or the Company with respect to the certificate alleged to have been lost, stolen or destroyed.

Any certificate which immediately prior to the Effective Time represented outstanding Shares that were transferred pursuant to Section 3.1, and not deposited, with all other instruments required by Section 4.1, on or prior to the sixth anniversary of the Effective Date shall cease to represent a claim or interest of any kind or nature as a shareholder of the Company or for the receipt of cash. On such date, the cash to which the former Holder of the certificate referred to in the preceding sentence was ultimately entitled shall be deemed to have been surrendered for no consideration to Parent. None of Parent or the Company shall be liable to any Person in respect of any cash delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. In addition, in the event of the surrender of a certificate of Shares that is not registered in the transfer records of the Company under the name of the Person surrendering such certificate, the amount of cash to which the registered Holder is entitled pursuant to Section 3.1 shall be paid to such a transferee if such certificate is presented to the Depositary and such certificate is duly endorsed or is accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer Taxes or any other Taxes required by reason of such payments being made in a name other than the registered Holder have been paid. If any amount of cash to which the registered Holder is entitled pursuant to Section 3.1 is to be delivered to a Person whose name is other than that in which the certificate surrendered in exchange therefor is registered, it shall be a condition of such delivery that the Person requesting such delivery shall pay any transfer or other Taxes required to be paid by reason of such delivery to a Person whose name is other than that of the Holder of the certificate surrendered or shall establish to the reasonable satisfaction of Parent that such Tax has been paid or is not applicable.
