"Company"),  we are familiar with the Company's  Registration  Statement on Form

Exchange  Commission  (the "SEC") under the  Securities Act of 1933 (as amended,
the "Act"),  on the date hereof,  with respect to the offering and issuance from
time to time by the Company of up to  $400,000,000  aggregate  offering price of
the  following:  (i)  one or more  series  of its  debt  securities  (the  "Debt
Securities"),  which may be senior debt  securities,  senior  subordinated  debt
securities or subordinated debt securities,  (ii) shares of its Preferred Stock,
par value $.10 per share (the "Preferred  Stock"), or (iii) shares of its Common
Stock,  par value $.01 per share (the "Common  Stock").  All  capitalized  terms

to agreements and instruments  executed by natural persons,  we have assumed the
legal competency of such persons.
