AmeriVest Properties Announces Fourth Quarter 2003 Occupancy and Other
Information

    DENVER--(BUSINESS WIRE)--Feb. 13, 2004--AmeriVest Properties Inc.
(AMEX:AMV) announced today property occupancy information as of
December 31, 2003. At December 31, 2003, portfolio occupancy was
84.2%, compared to 88.0% at December 31, 2002, and 86.8% at September
30, 2003. "Same-store" occupancy (buildings owned for the entire year)
was 88.9%, compared to 89.9% at the end of 2002. This decrease in
occupancy reflects ongoing challenges in AmeriVest's core markets.
    "Although we are never satisfied with a portfolio occupancy rate
of less than 90%, we are very pleased that our same-store occupancies
and average rent declined only 1% during an extremely difficult year
for office leasing. We are also pleased to have acquired four quality
buildings in Phoenix and Dallas during the year, which we hope to
reposition for our target small-business customers during 2004. We
continue to see increased activity and leasing momentum in all our
markets and remain confident that our focus on providing the best
office space for small- and medium-size companies in markets
well-positioned for long-term growth will result in higher occupancies
over the long term," said Charles Knight, President and Chief
Operating Officer of AmeriVest.
    AmeriVest also noted that during the fourth quarter of 2003, it
incurred additional unbudgeted corporate and operating charges of
approximately $600,000 related to recruiting, severance and other
personnel expenses, rent and bad debt write-offs related to tenants
going out of business and adjustments for unanticipated property tax
and utility increases. On February 26, 2004, the Company intends to
release its financial results for the fourth quarter and year ended
December 31, 2003.
