5. Severance Liability

During 2012, we entered into a separation agreement and a release with our former Chief Executive Officer and member of our board of directors, and in 2013 we entered into a separation agreement and a release with a former vice president level employee. Under the terms of these agreements and releases, we agreed to provide each individual with salary continuation and medical coverage payments for predetermined lengths of time. In addition, we agreed to provide the former Chief Executive Officer with certain stock option benefits including the grant of an additional stock option, accelerated vesting of all then-outstanding options previously granted to him, and an extension of the post-employment exercise period for all of his options, including the newly granted one. All costs associated with the modification of his options and the costs of the new option grant were immediately recognized upon his separation.

In July of 2014 we agreed to provide a terminated employee a lump sum salary payment and 4 months of medical coverage payments which ended December 31, 2014.

As of December 31, 2014 and June 30, 2015, $0 remained outstanding associated with the severance liabilities. During the six-month period ended June 30, 2014, we made total payments of $64,600 to individuals whom these severance amounts were due.
