Likewise, this clause shall apply to any other Tender Contracts entered into by the Seller Affiliate with any public administrations or those subject to the aforementioned public procurement rules, relating to the Spain Business, and not listed as Spain Tender Contracts in Schedule 2.1.1(b)-I (including, where applicable, private contracts (contratos privados) and publicly funded contracts (contratos subvencionados), bids submitted in the context of public tenders, tenders awarded pending contractual formalization and administrative contracts).

(d)As indicated above, after Closing has occurred, a second communication will be submitted by the Parties to the relevant public contracting authorities of the Spain Tender Contracts informing that the Transaction has been completed, for the purposes of Articles 98 and 144 of the Public Sector Contracts Law in the form attached hereto as Schedule 5.1.1(d).

Certain indemnification obligations of Seller Parent and Seller Affiliate, as applicable, with respect to matters arising under or relating to this Agreement are set forth on Schedule 7.2(f) of the Master Purchase Agreement, as amended. Notwithstanding anything to the contrary herein, Spanish Law shall apply solely to the extent necessary to determine the existence, nature, and amount of any Damages (as defined in the Master Purchase Agreement) owed to Purchaser Parent or Purchaser Affiliate pursuant to Schedule 7.2(f) and shall have no application to any procedural, administrative, or process-related aspects of any indemnification claim brought thereunder. All matters relating to indemnification procedures, processes, and dispute resolution, including without limitation the assertion, defense, settlement, and resolution of indemnification claims, shall be governed exclusively by the Master Purchase Agreement and the Laws of the State of New York, including but not limited to Section 7.5 of the Master Purchase Agreement (Exclusivity of Indemnification Remedies), Section 7.6 of the Master Purchase Agreement (Indemnification Procedures), Section 7.7 of the Master Purchase Agreement (Tax Treatment of Indemnification Payments), and Section 9.7 of the Master Purchase Agreement (Governing Law; Dispute Resolution). In no event shall Purchaser Parent or Purchaser Affiliate be entitled to recover,

11


or shall Seller Parent or Seller Affiliate be obligated to pay, more than once for any Damages arising out of the same facts, circumstances, events, or occurrences, regardless of whether such recovery is sought under this Agreement or the Master Purchase Agreement.

13.Taxes. All taxes and expenses incurred in connection with the Agreement shall be paid in accordance with the allocation in the Master Purchase Agreement.
14.Miscellaneous.
14.1Master Purchase Agreement. Sections 4.7 (Confidentiality), 6 (Termination) and 7 (Indemnification) of the Master Purchase Agreement shall be applicable mutatis mutandis to this Agreement.
14.2Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the Parties agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the Parties agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.
14.3Waiver. Any of the terms or conditions of this Agreement which may be lawfully waived may be waived in writing at any time by each Party which is entitled to the benefits thereof. Any waiver of any of the provisions of this Agreement by any Party hereto shall be binding only if set forth in an instrument in writing signed on behalf of such Party. Neither the waiver by a Party hereto of a breach of or a default under any one or more of the provisions of this Agreement, nor the failure of a Party, on one or more occasions, to enforce any of the provisions of this Agreement or to exercise any right or privilege hereunder shall thereafter be construed as a waiver of any subsequent breach or default of a similar nature, or as a waiver of any such provisions, rights or privileges hereunder.
14.4Amendment. This Agreement may not be amended, modified, altered or supplemented other than by a written instrument duly executed and delivered on behalf of the Purchaser Affiliate and the Seller Affiliate.
14.5Interpretation.
14.5.1The annexes to this Agreement are, for all intents and purposes, an integral part thereof, and, consequently, shall be binding on the Parties.
14.5.2All headings contained in this Agreement are solely for order and organization purposes and shall not entail any interpretation or limitation on the matters regulated by the provisions in which they are used.
14.5.3References to any law or regulation shall be construed as references to such law or regulation as the same may be amended, restated or replaced from time to time.

12


14.5.4The singular shall include the plural and vice versa.
14.5.5References to the words “include”, “including”, “in particular”, or any similar term or expression are not to be construed as implying any limitation and general words introduced by the word “other” (or any similar term) shall not be given a restrictive meaning by reason of the fact that they are preceded by words indicating a particular class of acts, matters or things.
14.5.6The Parties have negotiated, drafted and assessed the rights and obligations of this Agreement jointly and with their advisers, and therefore no contra proferentem criteria shall be applicable in the interpretation of the Agreement.
