They were convertible at any time (that's the problem I had with them), but the loan was not due until Aug. 2014. There was an event that triggered it. (Edit-out: early payment at 140.)
"ITEM 2.04 - TRIGGERING EVENTS THAT ACCELERATE OR INCREASE A DIRECT FINANCIAL OBLIGATION OR AN OBLIGATION UNDER AN OFF-BALANCE SHEET ARRANGEMENT
Under the 12% Secured Convertible Debenture (the "Debenture") we issued to WHC
Capital, LLC ("WHC") on August 1, 2013, as disclosed in our Current Report on
Form 8-K filed on August 19, 2013, we were required to register 300% of the
principal amount of the shares into which the Debenture may be converted.
Because such registration was not declared effective by the Securities and
Exchange Commission by December 9, 2013, the principal amount of the Debenture
has increased by 140% to $232,400.
