The first tranche of 1.25 million warrants expired unvested on March 1, 2014 and the second tranche of 1.5 million warrants expired unvested on December 31, 2014. There is one tranche of 2.25 million warrants remaining with a strike price of $1.98 and a qualifying order vesting date through September 2015 and an expiration date of August 2018. Any costs associated with the warrants will be recorded as a reduction of potential future revenue recorded under the arrangement. No warrants were vested and no expense was recorded as of January 31, 2015.

The warrant has a term of three years from the Closing Date. The warrants qualified for permanent equity accounting treatment.
