In the event the Company elects not to renew the Agreement at the end of its term, Mr. Sparacio is eligible to receive a one-time bonus of $75,000, an increase from $50,000 under Mr. Sparacio’s prior employment agreement. In addition, under the prior employment agreement, all of Mr. Sparacio’s unvested stock options and restricted stock units, with the exception of certain historical grants, were subject to accelerated vesting in the event of non-renewal. Pursuant to the new Agreement, the historical grants are now also subject to acceleration in the event of non-renewal, with a revised acceleration date of November 10, 2016 (assuming Mr. Sparacio remains employed on such date).
