                  manufacture, store or dispose of in or about the Premises or
                  the Building any (collectively "Hazardous Materials")
                  flammables, explosives, radioactive materials, hazardous
                  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
                  disposition of environmentally hazardous materials,
                  substances, or wastes (collectively "Environmental Laws").
                  Licensee shall protect, defend, indemnify and hold each and

                  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
                  that to the best of Landlord's knowledge, the Premises are
                  free of Hazardous Materials prior to occupancy by Licensee.

         4.3      Licensee is responsible for all of its agents and visitors and
                  shall ensure that they do not do anything, which Licensee is
                  not allowed to do. Licensee shall faithfully observe and

         shall be payable by Licensee upon request. Upon termination of this
         License Agreement, Licensee shall deliver the Premises to Licensor in
         the same condition as it existing upon commencement of this Agreement.

8.       INDEMNITY AND RELEASE; INSURANCE.

                  and its property manager and other agents (the "Protected
                  Parties") from and against any and all claims (and all related
                  liabilities, costs, and attorneys' fees, collectively
                  "Damages") arising from (a) Licensee's use of the Premises or

                  any of its agents or visitors in or about the Premises, and/or
                  (b) any breach or default by Licensee hereunder, unless such
                  Damages are due to Licensor's gross negligence or willful
                  misconduct. As a material part of the consideration to
                  Licensor, Licensee hereby assumes all risk of damage to
                  property or injury to persons in or about the Premises from
                  any cause whatsoever and waives all claims against Licensor
                  and/or the other Protected Parties on account of the same.

         8.2.     During the term hereof, Licensee shall maintain in full force

                  Licensee's indemnity obligations herein. In addition, Licensee
                  shall insure all of its personal property at 100% of its full
                  replacement value. All insurance shall contain a complete
                  waiver of subrogation in favor of Licensor and the other
                  Protected Parties. Except for insurance relating to personal
                  property owned by Comdisco. A certificate of all such
                  insurance (including a prohibition against change or
                  cancellation of coverage without 30 days prior notice to
                  Licensor) shall be delivered to Licensor prior to Licensee
                  entering the Premises. Any insurance maintained by Licensor
                  will apply in excess of, and not contribute with, insurance
                  provided by Licensor.

9.       ENTRY BY LICENSOR.

         Licensor and its agents shall have the right to enter the Premises for

         this License Agreement, (b) permit the use of the Premises by any
         person or persons other than Licensee, nor (c) sublicense all or any
         part of the Premises.

11.      DEFAULT BY LICENSEE.

         Time is of the essence hereof. Licensee shall be in default if Licensee
         fails to perform any obligation hereunder as and when due. In the event
         of such a default, Licensor shall have all rights and remedies allowed
         by law. In addition, Licensor shall have the right to terminate this
         License Agreement and/or Licensee's right to use the Premises. Upon any
         such termination, Licensee shall immediately yield up possession of the
         Premises and Licensor may take any and all action, including changing

         Agreement, the prevailing party shall be entitled to recover, in
         addition to all other sums and relief, its reasonable costs and
         attorneys fees incurred at and in preparation for arbitration, trial,
         appeal and/or review, including costs and attorneys fees in federal
         bankruptcy proceedings.

         given if delivered to the Premises to the attention of "General
         Counsel" or if sent by certified mail to the Premises to the attention
         of "General Counsel" or to the address (if any) shown at the end of
         this License Agreement.

                  state where the Building is located. This License Agreement
                  contains the entire agreement of the parties. This License
                  Agreement can be amended, or any right or provision waived,
                  only by written document signed by both parties.

         14.2     All obligations, liabilities, indemnities, waivers and
                  releases of Licensee hereunder, as well as the attorneys' fees
                  provision hereof, shall survive the expiration or termination
                  of this License Agreement and/or of Licensee's right to use
