provided, h owever , that if any Party shall have designated a different address by notice to the others, then to the last address so designated.

11.5 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void, unenforceable or against its regulatory policy, such determination shall not affect the enforceability of any others or of the remainder of this Agreement; and in connection with such term, provision, covenant or restriction of this Agreement which is held invalid, void, unenforceable or against regulatory policy, the Parties shall negotiate in good faith with a view to the substitution therefor of a suitable and equitable solution in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid term, provision, covenant or restriction and, absent any agreement by the Parties, such court of competent jurisdiction or other authority shall substitute therefore such term, provision, covenant or restriction as is legal, valid and enforceable but otherwise similar to the invalid term, provision, covenant or restriction.

11.8 Waiver. The failure of any Party to enforce any condition or part of this Agreement at any time shall not be construed as a waiver of that condition or part, nor shall it forfeit any rights to future enforcement thereof.

11.9 Governing Law; Jurisdiction. This Agreement (including any claim or controversy arising out of or relating to this Agreement) shall be governed by the law of the State of New York without regard to conflict of law principles that would result in the application of any Law other than the Law of the State of New York. All Actions arising out of or relating to this Agreement shall be heard and determined exclusively in the Supreme Court of the State of New York or the federal courts of the Southern District of New York located in Manhattan, and any appellate court from any thereof, in any Action arising out of or relating to this Agreement, the Other Agreements, the Transactions or for recognition or enforcement of any judgment relating thereto, and each of the Parties hereby irrevocably and unconditionally (a) agrees not to commence any such Action except in such courts, (b) agrees that any claim in respect of any such Action may be heard and determined in the Supreme Court of the State of New York and the federal courts of the Southern District of New York located in Manhattan, (c) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any Action in the Supreme Court of the State of New York or the federal courts of the Southern District of New York located in Manhattan, and (d) waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such Action in the Supreme Court of the State of New York and the federal courts of the Southern District of New York located in Manhattan. Each of the Parties hereto agrees that a final judgment in any such Action shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Each Party to this Agreement irrevocably consents to service of process in the manner provided for notices in S ection 11.4. Nothing in this Agreement will affect the right of any Party to this Agreement to serve process in any other manner permitted by Law.

11.10 Injunctive R elief. Notwithstanding anything to the contrary in this Agreement, either Party will have the right to seek temporary injunctive relief in any court of competent jurisdiction as may be available to such Party under the laws and rules applicable in such jurisdiction with respect to any matters arising out of the other Party’s performance of its obligations under this Agreement. The Parties agree that in the event a Party institutes an appropriate Action seeking injunctive/equitable relief for specific performance under this Agreement, the Party seeking such relief shall not be required to provide the other Party with service of process of a complaint and summons under the procedures set forth in any non-United States judicial process or system. Under such circumstances, the Party seeking such relief need only provide the other Party with two copies of a true, correct and lawfully issued summons and complaint, via FedEx (priority delivery).

11.11 A m end m en t . Any amendment, modification or supplement of or to any provision of this Agreement, including the Schedules hereto, shall be effective only in writing and signed by a duly authorized officer of the Parties.

11.12 Headings. The headings of the sections and subsections of this Agreement are inserted for convenience only and shall not be deemed to constitute a part hereof.

11.13 Counterparts. This Agreement may be executed manually or by facsimile by the Parties, in any number of counterparts, each of which shall be considered one and the same agreement and shall become effective when a counterpart hereof shall have been signed by each of the Parties and delivered to the other Party.

11.14 Schedules. Purchasers agree that any disclosure by Sellers in any Schedule attached hereto shall not establish any threshold of materiality or concede the materiality of any matter or item disclosed.

11.15 Construction. The language in all parts of this Agreement shall be construed, in all cases, according to its fair meaning. The Parties acknowledge that each Party and its counsel have reviewed and revised this Agreement and that any rule of construction to the effect that any ambiguities are to be resolved against the drafting Party shall not be employed in the interpretation of this Agreement.
