F3	Under Mr. Scheiner's arrangement with the Adviser, Mr. Scheiner holds the option for the benefit of the Fund and the Nexus Fund. Mr. Scheiner is obligated to turn over to the Adviser any net cash or stock received upon exercise of the option, which will offset advisory fees owed by the Fund and the Nexus Fund to the Adviser.
