conditions of any nature now or hereafter imposed or levied by any

the U.S. Department of Treasury, or
            
     (ii) to any item referred to in the preceding sentence that
would not have been imposed but for the failure by such Bank to
comply with applicable certification, information, documentation
or other reporting requirements concerning the nationality,
residence, identity or connections of such Bank with the United
States if such compliance is required by statute or regulation of the
United States as a precondition to relief or exemption from such

respect to payments made by the Trust hereunder or under such other

dispute in connection with this Agreement, the Notes or any of the other
Loan Documents, any rights or obligations hereunder or thereunder or the
