Gentlemen:

     We  refer  you to the  Company's  Registration  Statement  on Form S-8 (the

          awards under the 1998 Plan, and the issuance of up to 1,100,000 shares
          of Common Stock  pursuant to awards under the Director  Plan have been
          duly  approved  by the  board of  directors  of the  Company  and such
          shares,   when  issued  in  accordance  with  the  provisions  of  the
          applicable plan, will be legally issued, fully paid and nonassessable.
          We assume,  for these purposes,  that the issuance of any awards under
          the Plans and of the Common Stock  subject to such awards will be made
          pursuant to the applicable plan, in full accordance with the terms and
          conditions of the  applicable  plan and pursuant to this  Registration
          Statement.
