Commitment Related to Intellectual Property Legal Services

In September 2012, the Company engaged Handal and Associates (“Handal”) to provide IP legal services in connection with licensing and prosecuting claims of infringement of the Company’s patent portfolio. From September 2012 through August 2016, pursuant to a partial contingent fee arrangement, the Company paid a monthly retainer fee of $30,000 to Handal creditable against future contingency recoveries and a fee ranging from 33% to 40% of license fees. A new agreement, which supersedes and replaces all previous agreements, was executed effective September 1, 2016, reducing the monthly retainer fee to $22,500 so long as Handal is simultaneously litigating ten or fewer cases. Parties agreed to meet and discuss an increase in the amount of the monthly retainer should the number of cases exceed ten. Monthly retainers paid are creditable against future contingency recoveries. The Company has agreed to reimburse Handal for pre-approved expenditures advanced on behalf of the Company and to pay Handal a fee of 40% of any net license fee or settlement.
