The Company shall not be liable to make any payment hereunder to the extent payment is actually made to the Trustee under any such insurance policy. If the Trustee, Advisor/Protector, Members and/or Manager is required to pay any amount that the Company is obligated to pay hereunder except for the exclusion in this subsection, before payment is reasonably expected to be made under the insurance policy, the Company shall promptly advance the amount the Trustee, Advisor/Protector, Members and Manager are required to pay for which the Company is liable hereunder.

9. If any provision of this agreement is determined by a court to require the Company to do or to fail to do an act which is in violation of applicable law, such provision shall be limited or modified in its application to the minimum extent necessary to avoid a violation of law, and, as so limited or modified, such provision and the balance of this agreement shall be enforceable in accordance with their terms.
