CERTAIN FEDERAL INCOME TAX CONSEQUENCES The following tax discussion, when read in conjunction with the discussion of ""Certain Federal  Income  Tax  Consequences''  in  the  Base  Offering  Circular,  describes  the  material federal  income  tax  considerations  for  investors  in  the  Securities.  However,  these  two  tax discussions do not purport to deal with all federal tax consequences applicable to all categories of investors, some of which may be subject to special rules. Investors should consult their own tax advisors in determining the federal, state, local  and  any  other  tax  consequences  to  them  of  the  purchase,  ownership  and disposition of the Securities.
