On March 4, 2015, Mad Catz Interactive, Inc. (the “Company”) and Harmonix Music Systems, Inc. (“Harmonix”) entered into a Binding Term Sheet for the Co-Publishing of Rock Band 4 video game (“Term Sheet”). Pursuant to the Term Sheet, Harmonix primarily will be responsible for development, marketing and music licensing of the Rock Band 4 video game; and Mad Catz primarily will be responsible for hardware development and manufacturing, physical game manufacturing, distribution, and channel marketing costs related to the Rock Band 4 video game. Mad Catz will act as publisher of record for all Rock Band 4 hardware. In addition, Mad Catz will act as publisher of record for physical copies of the Rock Band 4 game in the event Harmonix does not enter into an agreement with an alternative publisher. Harmonix will act as publisher of record for all digital copies of the Rock Band 4 game and associated downloadable content. Harmonix has the option to seek an alternative publisher for the game, and in the event Harmonix obtains substantially complete terms with an alternative publisher on or before April 15, 2015 (a “Publishing Structure Change”), the Company and Harmonix will negotiate to amend the terms of the Term Sheet (or any subsequent agreement entered into pursuant thereto) to incorporate the Publishing Structure Change. In the event there is no Publishing Structure Change, Mad Catz will be entitled to publish the Rock Band 4 hardware/game bundles, physical copies of the Rock Band 4 stand-alone game, and Rock Band 4 stand-alone hardware. Under the Term Sheet, the Company and Harmonix intend to enter into a Long Form Agreement to fully contain the applicable rights and obligations of the parties.
