(i) Liens securing taxes, assessments, governmental charges (including, without limitation, water, sewer and similar charges) or levies or claims for labor, material and supplies that are not yet due and payable;

(ii) deposits or pledges made in connection with, or to secure payment of, worker’s compensation, unemployment insurance, old age pensions or other social security obligations; and deposits with utility companies and other similar deposits made in the ordinary course of business;

Notwithstanding the foregoing provisions of this §8.2, the failure of any Unencumbered Property to comply with the covenants set forth in this §8.2 shall result in such Unencumbered Property’s no longer qualifying as Unencumbered Property under this Agreement, but such disqualification shall not by itself constitute a Default or Event of Default, unless the cause of such non-qualification otherwise constitutes a Default or an Event of Default.”
