AmeriVest Announces Liquidating Cash Distribution.

DENVER -- AmeriVest Properties Inc. (AMEX: AMV), a real estate investment trust serving small to medium-size office tenants, announced today that its Board of Directors has declared an initial liquidating cash dividend of $3.50 per share, payable from the proceeds of completed sales of properties under its July 17, 2006 purchase and sale agreement with Koll/PER, LLC (Koll/PER), a limited liability company owned by The Koll Company of Newport Beach, California, and the Public Employee Retirement System of Idaho (PERSI). The dividend will be paid November 16, 2006 to shareholders of record as of November 10, 2006.

To date, AmeriVest has closed six of the 12 properties being purchased by Koll/PER under the terms of the purchase and sale agreement. The remaining properties are cross-collateralized by two loans, one of which is held by Morgan Stanley and the other of which is securitized. Closings on the remaining properties will be scheduled as loan assumption approvals are received from AmeriVest's mortgage lenders and other traditional closing activities are completed. There can be no assurance that any additional closings will occur under the purchase and sale agreement or otherwise

Given the progress of asset sales to date, and to ensure that a liquidating distribution is paid in 2006 to preserve the company's REIT status for the year, the Board of Directors has elected to make this initial distribution at this time. There can be no assurance with respect to the timing or amount of any other distribution or distributions to be made by AmeriVest.
