Unencumbered Asset means any Project which as of any date of determination, (a) is not subject to any Liens other than Permitted Liens set forth in Sections 9.5(i) through 9.5(v), (b) is not subject to any agreement (including any agreement governing Indebtedness incurred in order to finance or refinance the acquisition of such asset) which prohibits or limits the ability of the Borrower, or its Wholly-Owned Subsidiaries, as the case may be, to create, incur, assume or suffer to exist any Lien upon any assets or Capital Stock of the Borrower, or any of its Wholly-Owned Subsidiaries other than a Permitted Negative Pledge, (c) is not subject to any agreement (including any agreement governing Indebtedness incurred in order to finance or refinance the acquisition of such asset) which entitles any Person to the benefit of any Lien (but not subject to any Liens other than Permitted Liens set forth in Sections 9.5(i) through 9.5(v)) on any assets or Capital Stock of the Borrower or any of its Wholly-Owned Subsidiaries or would entitle any Person to the benefit of any Lien (but excluding the Permitted Liens set forth in Sections 9.5(i) through 9.5(v)) on such assets or Capital Stock upon the occurrence of any contingency (including, except in the case of a Material Credit Facility, pursuant to an “equal and ratable” clause), (d) is not the subject of any material architectural/engineering issue, as evidenced by a certification of the Borrower, and (e) is materially compliant with the representations and warranties in Article VI below. Notwithstanding the foregoing, if any Project is a “Superfund” site under federal law or a site identified in writing by the jurisdiction in which such Project is located as having significant environmental contamination under applicable state law, the Borrower shall so advise the Lenders in writing and the Required Lenders shall have the right to request from the Borrower a current detailed environmental assessment (or one which is not more than two years old for Unencumbered Assets owned as of the Agreement Execution Date), and, if applicable, a written estimate of any remediation costs from a recognized environmental contractor and to exclude any such Project from Unencumbered Assets at their election. No Project of a Wholly-Owned Subsidiary shall be deemed to be unencumbered unless such Project and all Capital Stock of such Wholly-Owned Subsidiary or any other intervening Wholly-Owned Subsidiary between the Borrower and such Wholly-Owned Subsidiary is unencumbered and neither such Wholly-Owned Subsidiary nor any other intervening Wholly-Owned Subsidiary between the Borrower and such Wholly-Owned Subsidiary has any Indebtedness for borrowed money (other than Indebtedness due to the Borrower).
