Indemnification. --------------- (a) Indemnitor shall protect, defend, indemnify, and hold harmless Lender and its respective successors and assigns, and the officers, directors, shareholders, and employees of each of them, in each case in their capacities as such (all such other persons and entities being referred to herein individually as an "INDEMNITEE" and collectively as "INDEMNITEES") from and against any and all claims, demands, inquiries, actions, suits, losses, costs, damages, fines, penalties, expenses, liabilities, judgments, proceedings, or injuries that seek to impose any liability on any Indemnitee attributable to Hazardous Materials or any violation of any Environmental Law and arising out of, or relating to the Indemnitor or the Mortgaged Property (each individually, an "ENVIRONMENTAL CLAIM" or, collectively, "ENVIRONMENTAL CLAIMS") which may be imposed upon or incurred by any Indemnitee, provided, however, that the indemnity provided by -------- ------- the Indemnitor to any Indemnitee pursuant to this Agreement shall extend only to Environmental Claims for which the act or activity giving rise to any such Environmental Claims occurred during the period of time in which the Indemnitor was the owner of title to the Mortgaged Property, and in no event shall the Indemnitor be liable in any way under this Agreement for any acts which occurred on, in or around the Mortgaged Property prior to the time at which the Indemnitor became the owner of title to the Mortgaged Property. (b) In the event that any investigation or remedial work of any kind ("REMEDIAL WORK") is required by any Environmental Law or is necessary to prevent a material adverse effect on the Mortgaged Property in connection with a release of a Hazardous Material on, in or about the Mortgaged Property, Indemnitor shall perform or cause to be performed all such Remedial Work. All costs and expenses of such Remedial Work shall be paid for by Indemnitor.

If the inspection and audit report discloses that no such material environmental problem exists or may exist, Lender shall reimburse Indemnitor for the cost of the inspection and audit. If such inspection indicates the presence of any Hazardous Materials in violation of any Environmental Law, Indemnitor will undertake and complete all Remedial Work required by any Environmental Law or reasonably necessary to prevent a material adverse effect on the Mortgaged Property. (c) Indemnitor shall give immediate written notice to Lender of any information obtained or received by Indemnitor relating to any Environmental Claim.
