                  wastes or materials, toxic wastes or materials, or other
                  similar substances, petroleum products or derivatives or any
                  substance subject to regulation by or under any federal, state
                  and local laws, regulations and ordinances relating to the
                  protection of the environment or the keeping, use or

                  liability or costs (including court costs and attorney's fees)
                  incurred by reason of any actual or asserted failure of Lessee
                  to fully comply with all applicable Environmental Laws, or the
                  presence, handling, use or disposition in or from the Premises
                  of any Hazardous Materials, or by reason of any actual or
                  asserted failure of Licensee to keep, observe, or perform any
                  provision of this paragraph. Licensor represents to Licensee

                  Damages are due to Licensor's gross negligence or willful
                  misconduct. As a material part of the consideration to
