In the event the Indemnified Parties have a good faith reason to believe that an environmental hazard involving a Hazardous Substance in violation of Environmental Law exists on the Property that, endangers any tenants or other occupants of the Property or their guests or the general public, upon reasonable notice from the Indemnitee, Indemnitor shall, at Indemnitor’s expense, promptly cause an engineer or consultant reasonably satisfactory to the Indemnified Parties to conduct any environmental assessment or audit (the scope of which shall be determined in the sole and absolute discretion of the Indemnified Parties) and take any samples of soil, groundwater or other water, air, or building materials or any other invasive testing requested by Indemnitee and promptly deliver the results of any such assessment, audit, sampling or other testing; provided, however, if such results are not delivered to the Indemnified Parties within a reasonable period, then, upon reasonable notice to Indemnitor, the Indemnified Parties and any other Person designated by the Indemnified Parties, including but not limited to any receiver, any representative of a governmental entity, and any environmental consultant, shall have the right, but not the obligation, to enter upon the Property at all reasonable times to assess any and all aspects of the environmental condition of the Property and its use, including but not limited to conducting any environmental assessment or audit (the scope of which shall be determined in the sole and absolute discretion of the Indemnified Parties) and taking samples of soil, groundwater or other water, air, or building materials, and reasonably conducting other invasive testing, unless, in the case of such results not being delivered to the Indemnified Parties within a reasonable period, such results are delivered to the Indemnified Parties prior to the taking of any such activities by any such Person. If the Indemnified Parties shall have a right of access to the Property pursuant to this Section 3, Indemnitor shall cooperate with and provide the Indemnified Parties and any such Person designated by the Indemnified Parties with such access.
