Executive agree that, at any time during or after Executive’s employment with the Company, Executive will, without further compensation but at the Company’s sole expense, sign all papers and cooperate in all other acts reasonably required to secure or protect the Company’s rights in all such property identified in subsection (b) above, including without limitation executing written assignments therefor and applying for, obtaining and enforcing patents thereon in any and all countries.  In the event that Executive is unable or unavailable or will refuse to sign any lawful or necessary documents required in order for the Company to apply for and obtain a patent or patents with respect to any work performed by Executive (including applications or renewals, extensions, divisions or continuations), Executive hereby irrevocably designates and appoints the Company and its duly authorized officers and agents as Executive’s agents and attorneys-in-fact to act for and in Executive’s behalf, and in Executive’s place and stead, to execute and file any such applications and to do all other lawfully permitted acts to further the prosecution and issuance of patents with respect to such new developments with the same legal force and effect as if executed by Executive.
