No opinion of counsel is being filed because the Common Stock to be distributed
in connection with the Plan will consist exclusively of previously issued shares
that are presently held by the registrant as treasury shares and will not
constitute original issuance shares; further, no opinion is being furnished with
respect to ERISA compliance because the Plan covered by the registration
statement is not subject to the requirements of ERISA.

No opinion of counsel is being filed because the Common Stock to be distributed
in connection with the Plan will consist exclusively of previously issued shares
that are presently held by the registrant as treasury shares and will not
constitute original issuance shares; further, no opinion is being furnished with
respect to ERISA compliance because the Plan covered by the registration
statement is not subject to the requirements of ERISA.
