In relation to any legal action or proceedings to enforce this Agreement or arising out of or in connection with this Agreement (“Proceedings”) each of the Parties irrevocably submits to the exclusive jurisdiction of the District Court Frankfurt and waives any objection to Proceedings in such court on the grounds of venue or on the grounds that the Proceedings have been brought in an inappropriate forum.  However, either party shall be free to seek appropriate injunctive relief without compliance with the mediation procedures set forth herein. Notwithstanding the foregoing, UMC Mainz shall be permitted to enforce claims for payment under Article 4 of this Agreement against ARCA before any court of competent jurisdiction under the laws of the United States also within the United States.

The terms and provisions contained in this Agreement constitute the entire Agreement between the parties and shall supersede all previous communications, representations, agreements or understandings, either oral or written, between the parties hereto with respect to the subject matter hereof, and no agreement or understanding varying or extending this Agreement will be binding upon either party hereto, unless in writing which specifically refers to this Agreement, signed by duly authorized officers or representatives of the respective parties, and the provisions of this Agreement not specifically amended thereby shall remain in full force and effect according to their terms.

The provisions and clauses of this Agreement are severable, and in the event that any provision or clause is determined to be invalid or unenforceable under any controlling body of the law, such invalidity or unenforceability will not in any way affect the validity or enforceability of the remaining provisions and clauses hereof.

This Agreement may be assigned by either party upon thirty (30) days prior written notice.
