Each of the Company and each Significant Subsidiary is duly qualified to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except for such jurisdictions where the failure to so qualify or to be in good standing would not, individually or in the aggregate, result or reasonably be expected to result in a material adverse effect on the condition, financial or otherwise, or on the earnings, business, properties, assets or results of operations, whether or not arising from transactions in the ordinary course of business, of the Company and its Subsidiaries, taken as a whole (a “Material Adverse Effect”). All of the issued and outstanding shares of capital stock, or similar equity interest, of each Subsidiary have been duly authorized and validly issued, are fully paid and nonassessable and are owned by the Company, directly or through subsidiaries, free and clear of any Lien, except that the Company’s obligations under the Credit Agreement are secured by a negative pledge on any of the Company’s non-mortgage properties.
