         4)  Hazardous  Materials.  To the  best  knowledge  of  Lessor,  (a) no

         Lessee, its agents, contractors,  stockholders,  directors, successors,
         representatives,  and assigns  from and  against,  all  losses,  costs,
         claims,  liabilities and damages (including attorneys' and consultants'
         fees) of every type and nature,  directly or indirectly  arising out of

         or about the Building, the Development, or the soil, air, improvements,
         groundwater  or  surface  water  thereof,   or  the  violation  of  any
         environmental  Law,  except  to the  extent  that any of the  foregoing
         actually results from the release or emission of Hazardous  Material by
         Lessee or Lessee's  Parties in  violation of  applicable  environmental
         Laws.  "Hazardous  Material"  shall mean any  material  which is now or
         hereafter regulated by any governmental  authority which poses a hazard
         to the  environment  or human  health.  Hazardous  Materials  shall not
         include  products  used by Lessee for  typical  office  and  janitorial
         purposes.

         5) Repairs and  Maintenance.  Lessor shall perform and  construct,  and
         Lessee  shall  have no  responsibility  to perform  or  construct,  any
         repair,  maintenance  or  improvements  which  could  be  treated  as a
         "capital expenditure" under generally accepted accounting principles.

         6) Lessor's  Insurance;  Waiver of  Subrogation.  Lessor shall maintain
         "all risk" property  insurance  insuring against risk of loss or damage
         to the  Building  and the  Development  for the full  replacement  cost
         thereof.  Notwithstanding anything in the Lease to the contrary, Lessor
         and  Lessee  hereby  release  each other and their  respective  agents,
         employees,  successors, assignees and sublessees from all liability for
         injury to any  person or  damage to any  property  that is caused by or
         results  from a risk  which  is  actually  insured  against,  which  is
         required to be insured against under the Lease, or which would normally
         be covered  by "all risk"  property  insurance,  without  regard to the
         negligence  or willful  misconduct of the person or entity so released.
         All of Lessor's and Lessee's repair and indemnity obligations under the
         Lease  shall be subject to the waiver  and  release  contained  in this
         paragraph.  Each party shall cause each insurance  policy it obtains to
         provide  that the  insurer  thereunder  waives all  recovery  by way of
         subrogation as required  herein in connection with any injury or damage
         covered by such policy.

         7) Remedies. Lessor shall have no security interest or lien on any item
         of Lessee's  trade  fixtures,  furniture,  equipment and other personal
         property ("Lessee's Property"). Within ten (10) days following Lessee's
         request, Lessor shall execute documents reasonably acceptable to Lessee
         to evidence  Lessor's waiver of any right,  title,  lien or interest in
         Lessee's Property and giving any lenders holding a security interest or
         lien on Lessee's  Property  reasonable rights of access to the Premises
         to remove such Lessee's Property, provided that such lenders repair any
         damage  caused by such  removal.  Lessor  shall use its best efforts to
         mitigate  any damages  resulting  from a default by Lessee,  and Lessee
         shall not in any event be liable for


                                       11



         any damages reasonably mitigable by Lessor.  Lessor waives any right of
         distraint, distress for rent or Lessor's lien that may arise at law.

         8)  Subordination.  The  subordination  of Lessee's rights and interest
         under the Lease to any  mortgage or deed of trust  shall be  contingent
         upon Lessee's having received from any such mortgagee or beneficiary of
         any deed of trust a written  recognition  agreement in form  reasonably
         satisfactory  to Lessee  providing  that  Lessee's  rights and interest
         shall  not be  disturbed  in the event of any  foreclosure  of any such
         mortgage or deed of trust and confirming  that Lessee shall receive all
         of the rights and services provided for under the Lease.

IN WITNESS WHEREOF, the parties have executed this Addendum.
