Notwithstanding any other provision of this Agreement or the Articles no Shareholder may transfer or otherwise dispose of any right or interest (whether legal, equitable or otherwise) in or grant any Encumbrance over any of its Shares to any person (Transferee) who is not a party to this Agreement unless the proposed Transferee shall prior to such transfer have entered into and lodged with the Company a Deed of Adherence. On receipt of such Deed of Adherence by the Company and upon completion of the transfer the Transferee shall be deemed for all purposes to be a party to this Agreement and to be bound by the provisions and have the benefit of all covenants and undertakings contained in this Agreement (to the extent they remain to be performed) as if such person was a party to this Agreement and named in this Agreement as a party of the same part as the transferor. The provisions of this clause 4.3 shall apply also to any issue of Shares to a person who is not, at the date of such issue, a party to or deemed to be a party to this Agreement and such person will be considered a Shareholder and the Company hereby covenants and agrees that unless the holders of a majority of the Ordinary Shares otherwise agree in writing, it shall be a condition to the issuance of Shares to any person (other than pursuant to the ESOP) that such person shall execute a Deed of

12

Adherence and be bound by the provisions and have the benefit of all covenants and undertakings contained in this Agreement (to the extent they remain to be performed). Furthermore, the Company covenants that it shall be a condition to the issuance of Shares to any person pursuant to the ESOP that such person execute a deed of adherence in such form as the holders of a majority of the Ordinary Shares approve in writing under which such person agrees to be bound by the provisions of clauses 4.2 and 4.5 hereof.

1) the Sellers may procure that the Offer is extended on the same terms to those Shareholders to whom it was not already made (the Dragged Shareholders) (and if the Offer is for less than all of the then outstanding shares of the Company, pro rata to their shareholdings);

2) on procuring that the Offer is extended to the Dragged Shareholders, if the Dragged Shareholders or any of them have not accepted the Offer at the time that the Sellers have accepted it the Sellers will be entitled to accept the Offer on behalf of the Dragged Shareholders (and if the Offer is for less than all of the then outstanding shares of the Company, pro rata to their shareholdings) and for such purpose each Dragged Shareholder (with the exception of Enterprise Ireland) hereby irrevocably appoints each of the Sellers as his attorney to accept the Offer on his behalf and to execute and deliver all documents and instruments required to give effect to such acceptance and to the sale of all of the then outstanding shares of the Company or such proportion of the issued share capital of the Company as the Sellers may direct, which shall if the Sellers so wish, include all of the Sellers’ Shares). Enterprise Ireland shall execute and deliver all documents and instruments reasonably required by the Sellers to give effect to the acceptance by the Sellers of the Offer on behalf of Enterprise Ireland and to the sale of all of the then outstanding shares of the Company or such proportion of the issued share capital of the Company as the Sellers may direct. The Sellers shall procure that the Purchaser will pay to a Dragged Shareholder the consideration for such Dragged Shareholder’s Shares sold by transferring the consideration to such bank account as may be notified by such Dragged Shareholder to the Sellers, and failing such notification by delivering by hand a cheque for the amount payable to such Dragged Shareholder to the address of such Dragged Shareholders shown in the Register of members of the Company Shareholder and on proof that such cheque was delivered by hand, the Sellers and the Purchaser shall be deemed to have discharged all moneys due to such Dragged Shareholder in respect of the sale of some or all of his Shares pursuant to the Offer.

5.1.3. any Shares in respect of which an offer to a Shareholder is accepted shall be issued on the basis of such offer and the Shareholder will be obliged to subscribe for and consummate the purchase of such Shares accordingly;

5.1.4. if any offer is rejected or deemed to have been rejected by a Shareholder, the Shares comprised therein shall be offered for subscription on the same terms to the other Shareholders who have accepted the offers made to them under clause 5.1.1 and in the event of competition their entitlements to subscribe will be proportionate to the numbers of Shares held by them respectively; and

5.1.5. any Shares so offered which are still not taken up shall be offered to the other Shareholders of the Company in accordance with clause 5.2 to 5.5 and after such further offers may at the discretion of the Board, be allotted to any third party but on the same terms any Shares not allotted as they were offered to Shareholders pursuant to this clause 5.
