distributions as is equal, together with the Subject Securities previously

alleged omission) to state therein (or in any related registration statement,
notification or the like) a material fact required to be stated therein or

interest thereon (i) at the rate of 10.5% per annum with respect to amounts
owing to the Noteholders (as Assignees) and (ii) at a rate equal to the
