Operator may maintain such insurance coverage with respect to the Aircraft and any flights made under this Agreement as Operator may elect in its sole discretion, including aircraft physical damage coverage (hull insurance) and liability coverage for bodily injury and property damage. Operator shall retain all rights and benefits with respect to the proceeds payable under the hull insurance as a result of any incident or occurrence while an Aircraft is being operated on behalf of Lessee under this Agreement. Lessee shall be named as an additional insured on liability insurance policies maintained by Operator on the Aircraft with respect to flights conducted pursuant to this Agreement. Any hull insurance maintained by Operator on the Aircraft shall include a waiver of any rights of subrogation of the insurers against Lessee. Notwithstanding the foregoing and subject to the limitations of FAR 91.501(d), upon Operator’s request, Lessee shall, at Operator’s request, reimburse Operator for the cost and expense of any additional insurance obtained for any specific flight.
