Nodrog, not sure I follow your question. The positive news releases were designed to get the share price to a level that it would make financial sense to exercise the warrants. So at least to .76.

If that had happened, the exercise money would come into Poet's treasury. If the warrant holders were sufficiently excited by the news releases to increase their position in Poet, they would have just bought the stock on the market for far less thst .75. 

The extensions were courtesies to those that had come to Poet's aid when they bought the debentures, but at the same time, Poet would shore up their balance sheet if the warrants were exercised
