4.2.Security for Costs.  If the potential costs associated with the actions required in Section 4.1, the release of any unpermitted lien against all or any portion of the Property and/or the release or other satisfaction of the liability, if any, of Indemnitors with respect to all or any portion of the Property arising under or related to any of the applicable Environmental Laws or any Environmental Enforcement Action are determined by Agent, in good faith, to exceed $1,000,000.00, Agent shall have the right (in addition to any other right or remedy) to require Indemnitors to provide, and Indemnitors shall provide within thirty (30) days after written request therefor, a bond, letter of credit or other similar financial assurance, in form, amount and substance reasonably satisfactory to Agent, in its good faith judgment based on the reasonably estimated costs for such matter, evidencing to Agent’s reasonable satisfaction that the necessary financial resources will be unconditionally available to pay for all of the foregoing.

4.3.Environmental Assessments.  Without limitation of the provisions of Section 5 below, Agent shall have the right to require Indemnitors, at Indemnitors’ own cost and expense, to obtain a professional environmental assessment of each portion of the Mortgaged Property in accordance with Agent’s then standard environmental assessment requirements and sufficient in scope to comply with the requirements of Section 5.1 upon the occurrence of an Event of Default.

5.Agent’s Rights to Inspect the Property and Take Remedial Actions.

5.1.Assessments.  In addition to, and not in limitation of any of its other rights and remedies under this Agreement, as long as any Obligation with respect to the Indenture remains outstanding, so long as any Event of Default has occurred and is continuing, Agent shall have the right, but not the obligation, through such representatives or independent contractors as it may designate, to enter upon the Mortgaged Property or any of same and to expend funds (provided, however, Agent shall use reasonable efforts to minimize (a) any disruption to Indemnitors’ business operations at the Mortgaged Property, and (b) all costs associated with each such assessment) to cause one or more environmental assessments of all or any portion of the Mortgaged Property to be undertaken, if Agent in its reasonable and good faith discretion at any reasonable time and upon reasonable notice to Indemnitors, and from time to time at reasonable intervals and upon reasonable notice to Indemnitors, determines that Hazardous Materials may exist at the Mortgaged Property in amounts or under circumstances that could give rise to a material liability under applicable Environmental Laws, which determination may be based on regulatory requirements and/or internal

5

5.2.3.Environmental Enforcement Actions.  Comply with, settle or otherwise satisfy any Environmental Enforcement Action, including, but not limited to, the payment of any fines or penalties imposed by any governmental authority and the payment of all amounts required to remove any lien or threat of lien on or affecting any of the Mortgaged Property; and
