Licensee may terminate and release its license rights hereunder only upon
providing sixty (60) days advance notice in writing to the Licensor. It is

period Licensee shall have corrected such contract default leading to the
cancellation by Licensor, this Agreement shall remain in full force and effect.

of $2,500 for its share of such costs in opposing any and all of such potential
claims of infringement.
