To the full extent permitted by applicable law, the Member, the Manager and the Officers shall be entitled to indemnification from the Company for any loss, damage or claim incurred by such Member, Manager or Officers by reason of any act or omission performed or omitted by such Member, Manager or Officers in good faith on behalf of the Company and in a manner reasonably believed to be within the scope of the authority conferred on such Member, Manager or Officers by this Agreement, except that the Member, the Manager or any Officer shall not be entitled to be indemnified in respect of any loss, damage or claim incurred by such Member, Manager or Officer by reason of its gross negligence or willful misconduct with respect to such acts or omissions; provided, however, that any indemnity under this Section 15 shall be provided out of and to the extent of Company assets only, and the Member shall not have personal liability on account thereof.
