specifically  relate to an earlier date,  in which case they were true,  correct
and complete in all material respects on and as of such earlier date.

                 F.       Absence of Default.  Except  for any Event of Default
and Potential  Event of Default waived  pursuant to Section 2 of this Amendment,
