WORK FOR HIRE STATEMENT. I hereby acknowledge and agree that all original works of authorship (the Works of Authorship) which are produced, developed or authored by me (whether alone or jointly with others), or otherwise resulting from my work within the scope of my employment with the Company and which are protectible by copyright are works made for hire, as that term is defined in the United States Copyright Act (17 U.S.C., Section 101). In the event that any rights to the Works of Authorship are deemed not to be works made for hire, or in the event that I should, by operation of law, be deemed to retain any rights in such Works of Authorship, I hereby irrevocably assign, without any further consideration and regardless of any use by the Company of any such Work of Authorship, all of my rights, title and interest, if any, in and to such Works of Authorship to the Company. I agree that the Company, as the owner of all rights to the Works of Authorship, has the full and complete right to prepare and create derivative works based upon the Works of Authorship and any derivative works of such Works of Authorship and to use, reproduce, publish, print, copy, market, advertise, distribute, transfer, sell, publicly perform and publicly display, and otherwise exploit by all means now known or later developed, such Works of Authorship and derivative works anywhere throughout the world.
