We note your Information Statement covers actions taken that appear to involve a merger and require the increase in authorized shares of common stock.  Given the nature of the actions to be taken, it is unclear why your Information Statement does not include Items 11, 13 and 14 of Schedule A, pursuant to Note A of that Schedule.  Please advise or revise.
