(c) This Agreement constitutes the entire agreement of the parties with respect to the subject matter hereof and is intended to supersede all prior negotiations, understandings and agreements with respect thereto. Except as specifically set forth in this Agreement, no provision of this Agreement may be modified or amended except by a written agreement signed by the parties hereto. (d) In the event that any provision of this Agreement is held to be invalid, prohibited or unenforceable in any jurisdiction for any reason, unless such provision is narrowed by judicial construction, this Agreement shall, as to such jurisdiction, be construed as if such invalid, prohibited or unenforceable provision had been more narrowly drawn so as not to be invalid, prohibited or unenforceable. If, notwithstanding the foregoing, any provision of this Agreement is held to be invalid, prohibited or unenforceable in any jurisdiction, such provision, as to such jurisdiction, shall be ineffective to the extent of such invalidity, prohibition or unenforceability without invalidating the remaining portion of such provision or the other provisions of this Agreement and without affecting the validity or enforceability of such provision or the other provisions of this Agreement in any other jurisdiction. (e) The Administrative Agent and each Secured Party agree that neither this Agreement nor any provision hereof may be waived, amended, supplemented or otherwise modified by the Administrative Agent or such Secured Party except in accordance with the terms of Section 8.4 of the Loan Agreement. (f) This Agreement shall be binding upon and inure to the benefit of each party hereto and its successors and assigns. (g) Each party shall take such further action and execute and deliver such further documents as may be necessary or appropriate in order to carry out the provisions and purposes of this Agreement. (h) This Agreement shall be construed in accordance with the laws of the Republic of Hungary. The parties hereto irrevocably agree that the Hungarian courts shall have jurisdiction to settle any dispute, suit, action or proceedings which may arise out of or in connection with this Agreement. 13 (i) This Agreement may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original and, all of which taken together shall constitute one and the same Agreement. In the event that any signature is delivered by facsimile transmission, such signature shall create a valid binding obligation of the party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such facsimile signature were the original thereof. 14 IN WITNESS WHEREOF, the parties hereto have caused this Security Agreement to be duly executed on the day and year first above written.
