AMERIVEST PROPERTIES ANNOUNCES SALE OF FINANCIAL PLAZA

AND AMENDED LOAN AGREEMENTS WITH PRIMARY BANK GROUP

DENVER, CO,  January 23, 2006 — AmeriVest Properties Inc. (AMEX: AMV) announced today that it has completed the sale of Financial Plaza in Mesa, Arizona. Financial Plaza, a 310,838 square-foot Class A office property was sold for $55,000,000, or approximately $177 per square foot to Crescent Real Estate Equities Limited Partnership. AmeriVest will record a net gain on the sale of approximately $15.5 million for financial reporting purposes. The property was approximately 91% leased at the time of sale. The estimated net cash proceeds of approximately $30 million, after repayment of approximately $23 million in first mortgage debt and approximately $2 million in closing and related costs and adjustments, will be used to repay indebtedness under AmeriVest’s unsecured credit facility, leaving a balance due under this facility of less than $1 million. The sole remaining asset to be sold under AmeriVest’s strategic asset sale plan announced September 1, 2005, Keystone Office Park in Indianapolis, Indiana, is under contract.

AmeriVest also announced a further loan agreement with its primary bank group which amends its unsecured revolving credit agreement and reinstates a revolving credit facility of up to $10 million to be used for working capital and other limited corporate purposes. The revolver is secured by the Company’s Greenhill Park property and matures December 28, 2006. The amendment also modifies certain covenant requirements and collateral provisions and requires the Company to extend the employment agreement with its Chief Executive Officer through the maturity of the loan.

The Company also announced amendments to the Change in Control and Employment Agreements with two of its officers as follows: The term of the employment agreement with Charles Knight, President and CEO, was extended through December 31, 2006, which satisfies the employment agreement requirement of the new loan amendment. The term of the employment agreement with John Greenman, Chief Investment Officer, was extended 8 days through January 25, 2006 to allow Mr. Greenman to complete the Financial Plaza transaction announced today.

Copies of the amended loan agreement and employment agreements will be filed with the Securities and Exchange Commission in a Form 8-K, together with pro forma financial information relating to the Financial Plaza transaction described above.
