They had 20 million in operating expenses which at their current burn rate was supposed to carry them another 2 years back in summer of 2015 so this should bring them far beyond when they expected to generate revenue.
So no need to rush to have them excecuted unless they felt the money may be needed for unforeseen setbacks - so to me the fact they are expiring is a good thing to prevent further dilution especially in the hands of people who have not bee nthe best for the SP in general.
As well willing to let them expire makes me think it is more likely current partnerships and NREs are more likely to be in place or the company feels we are on the right track.
