assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, conformed or
photostatic copies, and the authenticity of the originals of such copies. Where documents have been provided to us in draft form, we have assumed that the final executed versions of such documents will not differ materially from such drafts. </P>

other jurisdiction under the laws of which any of the entities comprising the Company have been formed, and (c)&nbsp;each of the written agreements to which the Company is a party will be implemented, performed, construed and enforced in accordance

with retroactive effect. Any such change or interpretation could affect our conclusions set forth herein. In this regard, an opinion of counsel with respect to an issue represents counsel&#146;s best judgment as to the outcome on the merits with
respect to such issue, is not binding on the IRS or the courts, and is not a guarantee that the IRS will not assert a contrary position with respect to such issue or that a court will not sustain such a position if asserted by the IRS. </P>
