The indemnifying Party will have the right to assume the defense of any suit or claim related to the Liability if it has assumed responsibility for the suit or claim in writing. The indemnified Party may participate in (but not control) the defense thereof at its sole cost and expense. The indemnifying Party shall not agree to any settlement of such action, suit, proceeding or claim without the prior written consent of the indemnified Party, which shall not be unreasonably withheld. It shall be reasonable for the indemnifying Party to withhold consent if the settlement of such action, suit, proceeding or claim or consent to any judgment in respect thereof that does not include a complete and unconditional

| 24 |

release of the indemnified Party from all Liability with respect thereto or if it imposes any Liability or obligation on the indemnified Party without the prior written consent of the indemnified Party.

The non-performing Party will notify the other Party of such Force Majeure within ten (10) days after such occurrence by giving written notice to the other Party stating the nature of the event, its anticipated duration, and any action being taken to avoid or minimize its effect.
