(AMEX: AMV) announced today that it has acquired the Chateau Plaza office building, located in Dallas, Texas for $22,000,000. Chateau Plaza contains 171,000 rentable square feet and is 98% leased. Chateau Plaza is located within Dallas' renowned Turtle Creek/Uptown District. The property's highly visible location at the northwest corner of McKinney Avenue and Fairmount Street, offers tenants quick access to a multitude of freeways and the McKinney Avenue trolley line. The 18-story building, on approximately one acre of land, was built in 1986 and is leased to 10 tenants. The largest tenant within Chateau Plaza is Dean Foods, which currently leases 120,607 rentable square feet and has been a tenant of the building since 1998. Dean Foods (formerly Suiza Foods) is a leading national specialty food producer. The Dean Foods lease terminates in December 2005, however, Dean Foods has an option to terminate as early as December 2003, upon payment of a substantial penalty. Chateau Plaza is being purchased at a first year capitalization rate in excess of 10.5%. The purchase price of $22,000,000 ($128/SF) is being paid with $15,400,000 from the proceeds of a loan from Fleet Bank and the balance in cash. William Atkins, CEO of AmeriVest, said, "This is the third acquisition to be funded from the proceeds of our June 2002 follow-on common stock offering. It is also our second core property acquisition in Dallas, which we have identified as one of our target expansion cities. To acquire a building of this quality in one of the best sub-markets in Dallas for small and mid-size tenants represents a tremendous opportunity. Upon the eventual termination of Dean Foods' lease, we plan to upgrade the building and market this exceptional space to smaller tenants." "We have not changed our small tenant strategy," said Atkins. "We believe that Chateau Plaza is the best small tenant building in the market and will evolve to an appropriate tenant mix over time."
