In this Agreement, unless the context dictates otherwise:

In the event that a provision of this Agreement is null and void or unenforceable (either in whole or in part), the remainder of this Agreement shall continue to be effective to the extent that, given this Agreement’s substance and purpose, such remainder is not inextricably related to the null and void or unenforceable provision. The Parties shall make every effort to reach agreement on a new clause whose effect differs as little as possible from the null and void or unenforceable provision, taking into account the substance and purpose of this Agreement.

No amendment to this Agreement shall have any force or effect unless it is in writing and signed by both Parties.

This Agreement contains the entire agreement between the Parties with respect to the subject matter covered hereby and supersedes all earlier agreements and understandings, whether oral, written or otherwise, between Parties.

5

To the extent permitted by law, the Parties hereby waive their rights under Articles 6:265 to 6:272 inclusive of the Civil Code to rescind (ontbinden), or demand in legal proceedings the total or partial rescission (ontbinding) of this Agreement or to nullify this Agreement because of error (dwaling).

Investor may assign this Agreement in whole but not in part to any of its Affiliates. Except for such assignments to Affiliates, the Investor may not transfer or assign this Agreement or any of its rights hereunder. Any transfer or assignment in violation of this Agreement shall be null and void and of no force and effect.

Without prejudice to Clause 7.7, in the event that (i) a Three Director Investor becomes a Two Director Investor, (ii) a Three Director Investor becomes a One Director Investor, or (iii) a Two Director Investor becomes a One Director Investor (in each case, because such Investor, together with its Affiliates, ceases to hold directly or indirectly the requisite amount of the Outstanding Shares of LBI set forth in Clause 4 of this Agreement), such Investor shall notify LBI within three Business Days of such event and, promptly following the written request of the Nominating and Governance Committee of the Supervisory Board, shall cause one or more of the nominees of the Investor, as applicable, to execute and deliver a resignation which shall

6

be effective with respect to LBI on the date of such resignation and shall not permit any such nominee or nominees to revoke any such resignation.

In the event that (i) a One Director Investor becomes a Two Director Investor, (ii) a One Director Investor becomes a Three Director Investor, (iii) a Two Director Investor becomes a Three Director Investor (in each case, because such Investor, together with its Affiliates, acquires directly or indirectly the requisite amount of the Outstanding Shares of LBI set forth in Clause 4 of this Agreement), or (iv) a nominee of the Investor on the Supervisory Board resigns his position or otherwise terminates his membership on the Supervisory Board, such Investor shall notify LBI within three Business Days of such event and, as soon as commercially practicable following the written request of the Investor, LBI shall use its reasonable best efforts to cause the Supervisory Board to take all of the actions that are necessary to ensure that the Investor is able to nominate to the Supervisory Board the number of members indicated in Clause 4 of this Agreement so that the relevant nominee is, or nominees are, appointed to the Supervisory Board within the shortest possible period of time (including, for the avoidance of doubt, the increase of the number of Supervisory Board members, the appointment of additional independent Supervisory Board members to ensure compliance with applicable listing standards, and the appointment of the Investor’s nominee in accordance with Clause 7.11); provided, however, that the failure of such Investor to so notify LBI within three Business Days shall not affect such Investor’s rights to appoint members of the Supervisory Board pursuant to this Agreement. For the avoidance of doubt, if the appointment of the Investor’s nominee(s) pursuant to this Clause 7.9 would cause the Supervisory Board to fail to have a majority of independent members under the applicable listing standards, the appointment of such Investor’s nominee(s) may be delayed for up to ninety (90) days in order to select and appoint a sufficient number of independent Supervisory Board members so that, upon the appointment of such Investor nominee(s), the Supervisory Board will be comprised of a majority of independent members.

As soon as practicable after the date on which the right to nominate one or more members to the Supervisory Board arises, the Investor shall submit to LBI all personal details LBI reasonably requires in connection with the appointment of a Supervisory Board member. Following such submission, LBI shall use its reasonable best efforts to cause the Supervisory Board to take all of the actions to appoint the relevant nominee or nominees as soon as practicable to the Supervisory Board in accordance with the provisions of Article 2:143 of the Civil Code and Article 12.4 of the Articles, which appointment shall terminate on the date of the next general meeting of shareholders of LBI, on which date the relevant nominee or nominees shall be nominated for (re)appointment to the Supervisory Board. If any Investor nominee, for any reason, is not appointed to the Supervisory Board during a general meeting of the shareholders of LBI, the Investor shall as soon as practicable put forward a nominee who shall be appointed to the Supervisory Board by the Supervisory Board in accordance with the

7

provisions of Article 2:143 of the Civil Code and Article 12.4 of the Articles, which appointment shall terminate on the date of the then following general meeting of shareholders of LBI, on which date an Investor nominee shall be nominated for appointment to the Supervisory Board.

In the event the Investor, together with its Affiliates, holds directly or indirectly 5% or more of the Outstanding Shares of LBI, the Investor can require the Supervisory Board to call (and LBI shall use its reasonable best efforts to cause to occur) a general meeting of shareholders at the shortest practicable notice in the event the ability to appoint an additional member of the Supervisory Board pursuant to Clauses 7.9 and 7.10 above would be frustrated by the fact that by doing so the Supervisory Board would need to exceed the 1/3 limit laid down in Article 2:143 of the Civil Code and Article 12.4 of the Articles.

This Agreement shall be exclusively governed by and construed in accordance with the laws of the Netherlands, without regard to any conflict of law rules under Dutch private international law.

All disputes arising in connection with this Agreement shall be finally settled in accordance with the arbitration rules of the Netherlands Arbitration Institute (NAI). The arbitral tribunal shall be composed of three (3) arbitrators: one selected by LBI, one selected by the Investor and the third agreed upon by the first two selected arbitrators. The place of arbitration shall be Amsterdam. The arbitral procedures shall be conducted in the English language. Consolidation of the arbitral proceedings with other arbitral proceedings pending in the Netherlands, as provided in Article 1046 of the Netherlands Code of Civil Procedure, is excluded.
