The Agent shall be required to join in such suitor action as may be necessary to assure the Assignor’s ability to bring and maintain any such suit or action in any proper forum so long as the Agent is completely satisfied that such joinder will not subject the Agent or any of the Holders to any risk of liability.

upon the whole or from time to time any part of the Patent Collateral, or any interest which the Assignor may have therein, and after deducting from the proceeds of sale or other disposition of the Patent Collateral all expenses (including all reasonable expenses for brokers’ fees and legal services), shall apply the residue of such proceeds toward the payment of the Notes as set forth in the Indenture. Notice of any sale, license or other disposition of any of the Patent Collateral shall be given to the Assignor at least ten (10) days before the time that any intended public sale or other disposition of such Patent Collateral is to be made or after which any private sale or other disposition of such Patent Collateral may be made, which the Assignor hereby agrees shall be reasonable notice of such public or private sale or other disposition. 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.

9. COLLATERAL PROTECTION.

If the Assignor shall fail to do any act that it has covenanted to do hereunder, or if any representation or warranty of the Assignor shall be breached, the Agent, in its own name or that of the Assignor (in the sole discretion of the Agent), may (but shall not be obligated to) do such act or remedy such breach (or cause such act to be done or such breach to be remedied), and the Assignor agrees promptly to reimburse the Agent for any reasonable and documented cost or expense incurred by the Agent in so doing.

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). This power of attorney shall be irrevocable for the duration of this Patent Security Agreement.

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.
