AMERIVEST PROPERTIES RECEIVES LETTER OF INTEREST IN PORTFOLIO

DENVER, CO, February 21, 2006 — AmeriVest Properties Inc. (AMEX: AMV), a real estate investment trust serving small to medium size office tenants, announced today that it has received a letter of interest for the acquisition of the entire AmeriVest portfolio from Lincoln Property Company Commercial, Inc., a Dallas based institutional real estate investor. AmeriVest recently announced that its Board of Directors had voted to adopt a plan of liquidation, which plan is subject to approval by the Company’s shareholders. The Company is currently working with Trammell Crow Company, its broker, to prepare offering materials for all of its properties as part of a comprehensive marketing process. The letter from Lincoln states that it “would consider investing a range of $130 to $150 million of equity above your estimated current loan balances of approximately $126 million.” Lincoln indicated that this range was based on analysis of public information and has requested additional information from the Company to perform a more thorough analysis. The Company currently has approximately $127.5 million of outstanding indebtedness.

Charles Knight, CEO of AmeriVest stated “We appreciate Lincoln’s interest in our portfolio. We have received and expect to receive many more indications of interest as a result of our Board’s recent adoption of a liquidation plan. We intend to achieve the highest value reasonably attainable for our shareholders in an expeditious manner; however, we must caution that until a prospective purchaser has completed their due diligence and a definitive purchase and sale agreement with respect to one or more of the Company’s properties has been signed there is no agreement on value. We have contacted Lincoln and have directed our broker, Trammell Crow Company, to provide them and all other interested parties with all requested information on the portfolio as soon as that information has been collected.”

The Company is providing this information under Regulation FD because the Company was made aware that the information contained in the letter from Lincoln was also provided selectively by Lincoln to certain shareholders of the Company. The Company does not expect to provide information on other non-binding indications of interest in the future unless otherwise required.”
