             We have reviewed the corporate action of the Company in connection

fact upon, originals or copies certified or otherwise identified to our
satisfaction, of such corporate records, agreements, documents and other
instruments and such certificates or comparable documents of public officials
and of officers and representatives of the Company, and have made such other and
further investigations as we have deemed relevant and necessary as a basis for
