ITEM 1.01 Entry into a Material Definitive Agreement
Tool Purchase and Informatics License Agreement, Amendment to CDP Agreement with First Solar

On February 6, 2013, we entered into a Tool Purchase and Informatics License Agreement (the "Purchase Agreement") with First Solar, Inc. ("First Solar").

Under the Purchase Agreement, First Solar will purchase certain equipment and we will grant First Solar non-exclusive licenses to our proprietary HPC platform and to our proprietary Informatics software, for use solely with the purchased equipment for a fixed period. We will also provide warranty services on the equipment under the Purchase Agreement.

In connection with the signing of the Purchase Agreement, we amended the Collaborative Development Program agreement that we entered into with First Solar in December 2012 (the "CDP Agreement"). The amendment modifies certain terms of the CDP Agreement to reflect the parties entering into the Purchase Agreement.

The foregoing descriptions of the Purchase Agreement and the amended CDP Agreement do not purport to be complete and are qualified in their entirety by reference to the agreements, which will subsequently be filed as exhibits to our 2012 Form 10-K.
