Fair Market Rental Value or "Fair Market Sales Value" shall mean with respect to any property or service as of any date, the cash rent or cash price obtainable in an arm's length lease, sale or supply, respectively, between an informed and willing lessee or purchaser under no compulsion to lease or purchase and an informed and willing lessor or seller or supplier under no compulsion to lease or sell or supply of the property or service in question, and shall, in the case of any Unit or an Owner Lessor's Interest, be determined (except pursuant to Section 17 of the Facility Lease or as otherwise provided below or in the Operative Documents) on the basis that (a) the conditions contained in Sections 7 and 8 of the Facility Lease shall have been complied with in all respects, (b) the lessee or buyer shall have rights in, or an assignment of, the Operative Documents to which the Owner Lessor is a party and the obligations relating thereto, (c) the Unit or the Owner Lessor's Interest, as the case may be, is free and clear of all Liens (other than Owner Lessor's Liens, Owner Participant's Liens and Indenture Trustee's Liens), (d) taking into account the remaining terms of the Site Lease and the Site Sublease, and (e) in the case of the Fair Market Rental Value, taking into account the terms of the Facility Lease and the other Operative Documents. If the Fair Market Sales Value or Fair Market Rental Value of the Owner Lessor's Interest is to be determined during the continuance of a Lease Event of Default or in connection with the exercise of remedies by the Owner Lessor pursuant to Section 17 of the Facility Lease, such value shall be determined by an appraiser appointed solely by the Owner Lessor on an "as-is", "where-is" and "with all faults" basis and shall take into account all Liens (other than Owner Lessor's Liens, Owner Participant's Liens and Indenture Trustee's Liens); provided, however, in any such case where the Owner Lessor shall be unable to obtain constructive possession sufficient to realize the economic benefit of the Owner Lessor's Interest, Fair Market Sales Value or Fair Market Retail Value of the Owner Lessor's Interest shall be deemed equal to $0. If in any case other than in the preceding sentence the parties are unable to agree upon a Fair Market Sales Value or Fair Market Rental Value of the Owner Lessor's Interest within 30 days after a request therefor has been made, the Fair Market Sales Value or Fair Market Rental Value of the Owner Lessor's Interest shall be determined by appraisal pursuant to the Appraisal Procedures. Any fair market value determination of a spare part or Severable Modification for purposes of Section 5.2(d) of the Facility Lease shall take into consideration any liens or encumbrances to which the spare part or Severable Modification being appraised is subject and which are being assumed by the transferee, and that such spare part or Severable Modification is being transferred on an "as-is", "where-is" basis.
