Dear Dan:

As you are aware, I have been asked to consider resigning from the board of directors of Oracle Corporation because of a perception that my new position as co-director of the Rock Center on Corporate Governance at Stanford University has the potential to raise issues that were unanticipated as of the time I initially joined the board.

While I am of the view that these concerns are misplaced, I have decided to resign my position as director effective as of June 2, 2006.

Sincerely,

/s/ Joseph A. Grundfest

Joseph A. Grundfest
