                  BUYS CENTERRA OFFICE BUILDING FOR $18,700,000

     DENVER, CO, November 12, 2002 -- AmeriVest Properties Inc. (AMEX: AMV)
announced today that it has acquired the Centerra office building, located in
Denver, Colorado for $18,700,000. The Centerra Building contains 186,000
rentable square feet and is 80% leased.

     The Centerra Building is located in the southeast quadrant of the City and
County of Denver, immediately adjacent to the intersection of I-25 and Colorado
Boulevard. The 17-story building and seven-story parking garage on 1.15 acres of
land was built in 1982 and is leased to 36 tenants, with an average tenant size
of 4,200 square feet. The Centerra Building is located directly adjacent to
AmeriVest's 141,000 square foot Sheridan Center project.

     The Centerra Building is being purchased at a first year capitalization
rate in excess of 10.5%. The purchase price of $18,700,000 ($100/SF) is being
paid with $13,100,000 from the proceeds of a loan from Fleet Bank and the
balance paid in cash.

     Charles Knight, President and chief operating officer of AmeriVest, said,
"This is the second acquisition to be funded from the proceeds of AmeriVest's
follow-on common stock offering which was completed in June 2002. We look
forward to the contribution this and future acquisitions will make to our funds
from operations. Centerra fits AmeriVest's target acquisition profile, with a
diversified rent roll in terms of both lease expirations and business sectors.
This property offers a strong mid-town location with great visibility and
access, as well as a range of amenities important to our tenant base, including
an in-house deli and exercise facility. We intend to upscale the property by
adding AmeriVest's standard package of amenities and services to tenants, such
as our state-of-the-art conference room facility."

     The current rent roll of the Centerra Building includes 19,000 square feet
leased to United Air Lines, Inc. "We are aware of the uncertainties regarding
United," said Knight. "As frequent travelers and Denver residents, we support
United in its quest to restructure outside of bankruptcy. Nevertheless, this is
a great small tenant building which we are pleased to own, regardless of the
outcome of United's negotiations."

tenants in select markets. Its common stock is listed on the American Stock
