AMERIVEST PROPERTIES ANNOUNCES KEYBANK AGREEMENT

DENVER, CO, October 22, 2004 – AmeriVest Properties Inc. (AMEX: AMV) announced today that as of October 20, 2004, it has entered into an agreement with KeyBank National Association as Administrative Agent for its Unsecured Revolving Credit Facility.  KeyBank has assumed and amended the Unsecured Credit Facility of $30,000,000 dated December 15, 2003 from Fleet Bank of Boston, a Bank of America company.  The amended KeyBank Unsecured Facility has been increased from $30,000,000 to $40,000,000 and the maturity date extended from November 12, 2005 to November 12, 2007.  The amended Unsecured Facility has the option of a one-time increase to $50,000,000, available up to December 31, 2005.   In addition, the original provision of the Unsecured Facility which required an annual thirty-day pay down to zero has been modified to a pay down to $20,000,000 with the additional option, at the Agent’s discretion, of a 90-day extension.

The amendment to the Unsecured Facility changes the interest rate options to LIBOR plus 350 basis points (from LIBOR plus 400 basis points) or the KeyBank Prime Rate Spread of Prime plus 275 basis points (from Prime plus 250). The previous annual Facility Fee has been removed and replaced with a one-time commitment fee that will be capitalized and amortized to interest expense over the life of the loan agreement.

The Company is currently negotiating a similar agreement with KeyBank on its Secured Credit Facility.

In discussing the transaction, Charles Knight, president and COO of AmeriVest, said, “We are pleased to enter into this new relationship with KeyBank and believe the loan restructuring allows us increased capacity and flexibility at a more attractive price.  KeyBank has been responsive to our needs and we feel they will be a valuable business partner to AmeriVest as we continue to grow.”
