The opinions set forth in paragraphs (1), (2), (5), (6), (7), (8) and (9) above are subject to the following exceptions, limitations and qualifications: (i) the effect of bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other similar laws now or hereafter in effect relating to or affecting the rights or remedies of creditors; (ii) the effect of general principles of equity, whether enforcement is considered in a proceeding in equity or at law, and the discretion of the court before which any proceeding therefor may be brought; (iii) the enforceability under certain circumstances under law or court decisions of provisions providing for the indemnification of or contribution to a party with respect to a liability where such indemnification or contribution is contrary to public policy; and (iv) any requirement that a claim with respect to any Securities denominated other than in United States dollars (or a judgment denominated other than in United States dollars with respect to such a claim) be converted into United States dollars at a rate of exchange prevailing on a date determined pursuant applicable law.

We express no opinion (i) concerning the enforceability of (a) the waiver of rights or defenses contained in the Indentures, the Debt Securities or the Guarantees or (b) the Guarantees to the extent that the obligations underlying the Guarantees are materially modified without the consent of the applicable Guarantor or (ii) with respect to whether acceleration of the Debt Securities may affect the collectibility of any portion of the stated principal amount thereof which might be determined to constitute unearned interest thereon.

We have also assumed that none of the terms of any Securities to be established subsequent to the date hereof, the issuance and delivery of any such Securities, or the compliance by the Company or any applicable Guarantor with the terms of such Securities will violate any applicable law or public policy or result in a violation of any provision of any instrument or agreement then binding upon the Company or any applicable Guarantor or any restriction imposed by any court or governmental body having jurisdiction over the Company or any applicable Guarantor.
