At any such sale or other disposition, the Agent may, to the extent permitted under applicable law, purchase or license the whole or any part of the Patent Collateral or interests therein sold, licensed or otherwise disposed of.

The Assignor hereby ratifies all that such attorney shall lawfully do or cause to be done by virtue hereof, and releases the Agent from any claims, liabilities, causes of action or demands arising out of or in connection with any action taken or omitted to be taken by the Agent under this power of attorney (except for the Agent’s gross negligence or willful misconduct).

13. COURSE OF DEALING.

No course of dealing among the Assignor, the Holders and the Agent, nor any failure to exercise, nor any delay in exercising, on the part of the Agent or any of the Holders, any right, power or privilege hereunder or under the Indenture shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder or thereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege.
