15.5 Should a provision of this Agreement, or a provision included in this Agreement at a later point in time, be or become invalid or null and void as a whole or in part, or should a gap in this Agreement become evident, this does not affect the validity of the remaining provisions or parts thereof. The invalid or null and void provision shall be deemed replaced, or the gap shall be deemed filled, as the case may be, with effect ex tunc by such valid regulation which in legal and economic terms comes closest to what the Parties intended or would have intended in accordance with the purpose of this Agreement if they had considered the point at the time of conclusion of this Agreement.

15.6 Unless expressly provided otherwise herein, the Purchaser shall not be entitled (i) to set off (aufrechnen) any rights and claims it may have against any rights or claims any other party may have under this Agreement or otherwise, or (ii) to refuse to perform any obligation it may have under this Agreement on the grounds that it has a right of retention (Zurückbehaltungsrecht) unless the rights or claims of the relevant party claiming a right to set off (Aufrechnung) or retention have been acknowledged (anerkannt) in writing by the relevant other party/parties or have been confirmed by final decision of a competent court (Gericht).

15.7 The Purchaser acknowledges and agrees that none of Sellers’ Beneficiaries shall have any liability or obligation towards the Purchaser or any Group Company, arising out of, in connection with or resulting from the activities in connection with the preparation, negotiation and implementation of this Agreement and the transactions contemplated thereby (including but not limited to any information or advice given or supplied by the Sellers’ Beneficiaries) unless expressly agreed otherwise in writing between any of the Sellers’ Beneficiaries and the Purchaser.

15.8 Subject to Closing,

15.8.1 the Purchaser hereby waives, and undertakes to not maintain, assert or enforce, any claims in existence at the Closing with respect to their grounds (dem Grunde nach bestehen) and not provided for in this Agreement against the Sellers and Sellers’ Beneficiaries, unless such claim is based on wilful misconduct (Vorsatz); and

15.8.2 the Sellers and RSGG shall waive and not enforce, and shall procure that the Sellers’ Affiliates shall waive and not enforce, any claim against any employee, officer or director of any Group Company, whatever the legal basis whether in connection with or arising out of the preparation, negotiation and implementation of the transactions contemplated by this Agreement or otherwise (in particular, but without limitation, in connection with any claim

of Purchaser or Purchaser Nominee against Seller and/or RSGG under or in connection with this Agreement), unless such claim is based on wilful misconduct (Vorsatz).

15.9 If any payment or other performance is made by the Sellers or RSGG to the Purchaser (or at the Purchaser’s request to any Group Company) or by the Purchaser to the Sellers and/or RSGG in respect of any claim under or in connection with this Agreement, the payment or in case of a non-financial performance its financial value shall be treated as a correction of the consideration paid by the Purchaser for the Shares under this Agreement and such consideration shall be deemed to have been reduced or increased, as the case may be, by the amount of such payment.

15.10 Any obligation or liability of the Sellersor RSGG (other than for a Breach of Clauses 5.2.3 through 5.2.6, 5.10or for a claim under Clause 11) under, or arising from, this Agreement lapses in the event that after Closing (i) the ultimate controlling shareholder (or a group of shareholders acting jointly) of the Purchaser ceases to control (directly or indirectly) the majority of the voting rights or board seats or otherwise the management of the Purchaser, or (ii) the majority of voting rights or board seats or otherwise the management of the Purchaser becomes (directly or indirectly) controlled by a person or group of persons acting jointly who were not in control before.

15.11 The Purchaser shall not, in whole or in part, transact in rem (verfügen) any claims (including future or contingent claims) arising from or in connection with this Agreement by way of sale, transfer, agreement, covenant, assignment, encumbrance or otherwise without the prior written consent of the Sellers. This shall, without limitation, also apply to any disposal by way of a demerger pursuant to Section 123 Reorganisation Act (UmwG) unless the Purchaser’s claims arising from and in connection with this Agreement are by way of such demerger transferred together with all or substantially all other assets of the Purchaser to one and the same receiving entity. The transfer restrictions pursuant to this Clause 15.11 shall not apply in the event of an assignment to lenders or syndicatees (or their agent(s)) in connection with the financing of all or part of the Preliminary Purchase Price or final Purchase Price or the Group’s business.

15.12 The Sellers and RSGG hereby agree, that each of, RSKG and RSGI and the representative for the Sellers as set forth in Clause 15.4, each individually and exempted from the restrictions set forth in Section 181 BGB, are hereby authorized to represent the Sellers through any declaration or notice (in each case made or received) or action or any other legal measure in connection with or under this Agreement. If and to the extent the Sellers and RSGG are entitled to enforce a right or make a declaration, any such enforcement or declaration shall only be valid if made collectively for and by all the Sellers and RSGG.

15.13 This Agreement shall be governed by German law. The English language version shall be determinative (even if a translation is made), provided that where German expressions are used in parentheses, the German expression shall be determinative.

15.14 In this Agreement:

15.14.1 any German legal term for any action, remedy, method of judicial proceeding, legal document, legal status, court, official or any legal concept or thing shall, in respect of any jurisdiction other than Germany, be deemed to include what most nearly approximates in that jurisdiction to the German legal term and any reference to any German statute shall be construed so as to include equivalent or analogous laws of any other jurisdiction; and

15.14.2 the headings shall not affect the interpretation of this Agreement.

15.15 Any dispute arising from or in connection with this Agreement and its consummation shall be finally settled by three arbitrators in accordance with the arbitration rules of the International Chamber of Commerce as applicable from time to time without recourse to the courts of law. The venue of the arbitration shall be Frankfurt am Main, Germany. The language of the arbitral proceedings shall be English, provided however, that the Parties shall be entitled to submit written evidence in the German language. In the event mandatory applicable law requires any matter arising from or in connection with this Agreement and its consummation to be decided upon by a court of law, the competent courts in and for Frankfurt am Main, Germany, shall have the exclusive jurisdiction thereupon.

15.16 The Parties agree that Willkie Farr & Gallagher LLP shall not be prevented from representing the Sellers and their Affiliates (other than any Group Company), directors and officers in any matter in relation to this Agreement, including, but not limited to claims for Breach, claims for indemnification and rescission. The same shall apply mutatis mutandis in relation to Clifford Chance LLP (or any associated firm or entity) representing the Purchaser and/or its Affiliates, including any Group Company following Closing.
