agreements  of the Lease as  amended  as the same may apply to a  month-to-month
tenancy.  If Tenant holds over after the  expiration of the 5th  Extension  Term
without  Landlord's  prior  written  consent,  Tenant will be deemed a tenant at
sufferance,  at a daily Rental,  payable in advance, equal to 200% of the Rental
per day payable  during the 5th Extension  Term, and Tenant will be bound by all
of the other terms, covenants and agreements of the Lease as amended as the same
may apply to a tenancy at sufferance.

     7.  BROKERS.  Landlord and Tenant  represent  and warrant that no broker or
agent negotiated or was instrumental in negotiating or consummating  this Tenant
Amendment  except  TrizecHahn  Colony Square GP LLC and Richard Bowers & Company
("Brokers"). Neither party knows of any other real estate broker or agent who is

Tenth  Amendment.   Pursuant  to  Georgia  Real  Estate  Commission   Regulation

by brokers or agents claiming through the other party.

     8.  CONFLICTING  PROVISIONS.  If any  provisions  of this  Tenth  Amendment
conflict with any of those of the Lease as amended,  then the provisions of this
Tenth Amendment shall govern.

     9. REMAINING LEASE  PROVISIONS.  Except as stated in this Tenth  Amendment,
