On August 22, 2011, the Registrant and Samsung Mobile Display Co., Ltd. (“SMD”) entered into an OLED Patent License Agreement (the “License Agreement”) and a Supplemental OLED Material Purchase Agreement (the “Supplemental Agreement”).  The OLED Patent License Agreement and the OLED Supplemental License Agreement between the Registrant and SMD, both dated as of April 19, 2005, as amended since that date, are terminated as of the effective date of the aforementioned agreements.

Pursuant to the License Agreement, the Registrant granted to SMD license rights under various patents owned or controlled by the Registrant for SMD to manufacture and sell certain phosphorescent organic light emitting diode (OLED) display products.  In consideration of the license grant, SMD agreed to pay the Registrant a license fee over the term of the License Agreement, which is through December 31, 2017.

Pursuant to the Supplemental Agreement, the parties agreed that SMD shall purchase from the Registrant, and the Registrant shall supply to SMD, a minimum amount of phosphorescent materials for SMD’s use in the manufacture of licensed products.  This minimum purchase commitment is subject to the Registrant being able to supply SMD with sufficient material to meet its requirements over the term of the Supplemental Agreement, which is concurrent with the term of the License Agreement.
