I don't know if there is a deadline to complete the merger, but there is a 90 day period in which the 15-12g can be voluntarily withdrawn. If it is withdrawn, then the 10k/q and other forms that would have been due April 1 need to be filed.
I recall Pham's options being listed as .25, .50, .75 and 1.00--I wonder if this is any indication of the potential future value in the event of a reverse merger.
