In the event the EGM is cancelled pursuant to the foregoing proviso, the Company shall duly call, give notice of, and hold the EGM as soon as practicable following the date of such cancellation.

(d) The Company shall ensure that the EGM is called, noticed, convened, held and conducted, in compliance in all material respects with all Applicable Law.

The approvals by Company shareholders of the resignations and appointments, the sale of the Company’s assets, the liquidation and dissolution of the Company and the distribution of the liquidation proceeds referred to in Section 2.04(a) (the “ Shareholder Approvals ”) will be effective as of, and conditional upon the occurrence of, the Closing. At the EGM, the Company shall use its reasonable best efforts to secure the Shareholder Approvals, such Shareholder Approvals to be effective as of, and conditional upon, the occurrence of the Closing.

Section 2.05. Directors . As soon as practicable after the date of this Agreement, and no later than the Offer Commencement Date, Buyer shall designate in writing to the Company the new members for the Boards for purposes of Section 2.04(a)(ii) (the “ Buyer Directors ”). For the avoidance of doubt, no fewer than two of the current directors of the Company (the “ Independent Directors ”), to be mutually agreed upon by the Buyer and the Company, shall remain on the supervisory board of the Company until the earlier of (i) such time after the Closing as the Buyer owns 100% of the outstanding Shares, (ii) the date the liquidation of the Company shall have been duly completed, or (iii) one year after the date hereof. The Company shall promptly take all actions and shall include in the Schedule 14D-9 such information with respect to the Company and its officers and directors as any Applicable Law may require in order to fulfill its obligations under Section 2.04. The Company shall take any and all other actions necessary to appoint the Buyer Directors to the Boards effective immediately following the Closing, and shall take all actions reasonably requested by Parent or Buyer in furtherance thereof. Parent shall supply to the Company in writing and be solely responsible for any information with respect to itself and its nominees, officers, directors and Affiliates required by any such Applicable Laws. Buyer shall cause all directors of the Company to be discharged at the annual general meeting of the Company held in 2015 for their acts of management or supervision, as applicable, as appears from the books and records of the Company, provided that no discharge shall have to be granted to a director for acts for which serious blame can be attributed to him or her ( een ernstig verwijt kan worden gemaakt ).

Section 2.06 . Further Actions . If requested by Parent, the Company and Buyer shall take as of the date of this Agreement or as soon thereafter as is reasonably practical, but effective no earlier than the Closing, the following actions to the extent reasonably necessary or desirable to accomplish the Asset Sale and/or the Reorganization: (a) in the case of the Company, the convening of

the necessary meetings of the Company shareholders and the Boards (including the EGM referenced in Section 2.04), (b) in the case of the Company, the consideration and approval of resolutions by the Boards for the purpose of the Reorganization and the consideration and approval of any Board resolutions (the “ Approval of the Boards ”) necessary or desirable to convene the EGM referenced in Section 2.04 and approve the Asset Sale to Buyer or its designee and the liquidation and dissolution of the Company, in each case as set forth in Section 2.04, subject to Section 2.07, and (c) in the case of Buyer and the Company, the execution of any and all reasonably requested documents, agreements or deeds that are necessary or desirable to effectuate the Reorganization and/or the Asset Sale and the filing or registration of any or all of such documents, agreements or deeds with the appropriate Governmental Authorities.

Section 2.07 . Reorganization . As promptly as practicable following the closing of the Subsequent Offering Period, Buyer shall effectuate a corporate reorganization (the “ Reorganization ”) of the Company and its Subsidiaries, which may include, (a) the Asset Sale, which may include, at Parent’s request, the amendment of the Articles of Association of the Company to permit the creation, among other things, of separate classes of shares in order to effect the foregoing or (b) if permissable under Applicable Law, the commencement of a compulsory acquisition by Buyer of Shares from any remaining minority shareholder in accordance with Section 2:92a of the Dutch Civil Code, in each case, which may be accompanied by the termination of the listing of the Shares on the NASDAQ and the deregistration of the Company under the 1934 Act and the cessation of the Company’s reporting obligations thereunder. For the avoidance of doubt and notwithstanding anything to the contrary contained in this Section 2.07, the Reorganization, if completed, shall be conducted in accordance with Applicable Law and shall result in all holders of Shares that were not tendered in the Offer or during the Subsequent Offering Period being offered or receiving in the Reorganization for each Share then held cash and CVRs in an amount equal to the Offer Consideration (in the case of Cash Consideration, without interest, less applicable withholding taxes with respect to the Offer Consideration), as soon as reasonably possible after the Closing. If Parent determines it is not reasonably practicable (which shall be deemed to include adverse tax consequences) to effectuate a Reorganization of the type described in clauses (a) or (b) of the first sentence of this Section 2.07, it will use reasonable best efforts to effectuate a Reorganization in a different manner with the prior approval of the Independent Directors, subject to the immediately foregoing sentence.

Section 2.08 . Certain Adjustments . Without limiting the other provisions of this Agreement, in the event that, during the period between the date hereof and the Expiration Time, the number of outstanding Shares or securities convertible or exchangeable into or exercisable for Shares shall be changed into a different number of shares or securities or a different class as a result of a reclassification,

21

stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, issuer tender or exchange offer or other similar transaction, then the Offer Consideration and any other amounts payable pursuant to this Agreement shall be equitably adjusted, without duplication, to reflect such change; provided that, in any case, nothing in this Section 2.08 shall be construed to permit the Company to take any action with respect to its securities that is prohibited by the terms of this Agreement.

Section 2.09. Withholding . Notwithstanding anything to the contrary in this Agreement, each of Parent, Buyer and the Company shall be entitled to deduct and withhold from the consideration otherwise deliverable under this Agreement, and from any other payments otherwise required pursuant to this Agreement, such amounts as Parent, Buyer, the Company or their Affiliates may be required to deduct and withhold with respect to any such deliveries (including any deliveries of CVRs) and payments under Applicable Law. To the extent that amounts are so withheld, they shall be treated for all purposes of this Agreement as having been delivered and paid to such Person in respect of which such deduction and withholding was made.

Intervening Event; and (ii) prior to effecting such Adverse Recommendation Change, (A) if requested by Parent, the Company shall have, and shall have caused the Company’s Representatives to, during the Intervening Event Notice Period, negotiate with Parent in good faith to make such adjustments in the terms and conditions of this Agreement so that an Adverse Recommendation Change is no longer necessary, and (B) Parent shall not have, during the Intervening Event Notice Period, made a written offer that that, after due consideration of such offer by the Boards in good faith and after consultation with their outside legal counsel and financial advisor of nationally recognized reputation, results in both Boards determining that it would not continue to be likely to be inconsistent with the director’s fiduciary duties under Applicable Law to not effect the Adverse Recommendation Change. In the event of any material changes to the circumstances applicable to the Intervening Event, after the start of the Intervening Event Notice Period, the Company shall be required to deliver a new written notice to Parent pursuant to Section 5.03(f)(i) and to comply with the requirements of this Section 5.03(f) with respect to such new written notice (including a new Intervening Event Notice Period) except the Intervening Event Notice Period shall be at least three Business Days (rather than the five Business Days contemplated by Section 5.03(f)(i) above).
