ITEM 9.01                                                               FINANCIAL STATEMENTS AND EXHIBITS

(b)                                 Pro forma financial information (unaudited)

The following unaudited Pro Forma Condensed Consolidated Financial Statements are included with this report:

As a result of the approval of the plan of liquidation (the “Plan”) by our stockholders, we adopted the liquidation basis of accounting as of June 1, 2006, and for all subsequent periods. Accordingly, all assets have been adjusted to their estimated net realizable value. Liabilities, including estimated costs associated with implementing the Plan, have been adjusted to their estimated settlement amounts. The estimates of the Company’s assets and liabilities will be periodically reviewed and adjusted as appropriate. The estimates for the valuation of real estate held-for-sale is based on the Purchase and Sale Agreement with Koll/PER, net of estimated selling costs and other potential costs relating to the liquidation. Actual values realized for assets and settlement of liabilities may differ materially from the amounts estimated. Estimated future cash flows from property operations were made based on the anticipated sales dates of the assets. However, due to the uncertainty in the timing of the anticipated sales dates and the cash flows therefrom, revenues and expenses generated by operations may differ materially from amounts estimated. These amounts are presented in the accompanying historic Statement of Net Assets in Liquidation at June 30, 2006. The net assets represent the estimated liquidation value of our assets available to our stockholders upon liquidation. The actual settlement amounts realized for assets and settlement of liabilities may differ materially, perhaps in adverse ways, from the amounts estimated. As such, it is not possible to predict the aggregate amount or timing of future distributions to stockholders and no assurance can be given that the eventual amount of distributions to be paid will equal or exceed the estimated net assets in liquidation included in the financial statements.

The unaudited Pro Forma Condensed Consolidated Statement of Net Assets in Liquidation as of June 30, 2006, reflects the financial position of the Company after giving effect to the disposition of Greenhill Park, Scottsdale Norte and Hackberry View (together referred to as Previously Reported Dispositions) and Parkway Centre III, as discussed in Item 2.01, as if such dispositions took place on June 30, 2006. The unaudited Pro Forma Condensed Consolidated Statements of Operations for the fiscal year ended December 31, 2005 and the five months ended May 31, 2006 give effect to the disposition of Greenhill Park, Scottsdale Norte, Hackberry View and Parkway Centre III as if such dispositions occurred on January 1, 2005.

The unaudited Pro Forma Condensed Consolidated Financial Statements have been prepared by the Company based upon historical financial statements of the Company, the operations of the

properties sold, and assumptions deemed proper by management and have been prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission and for the inclusion in the Form 8-K to be filed by AmeriVest Properties Inc. The unaudited Pro Forma Condensed Consolidated Financial Statements presented herein are shown for illustrative purposes only and are not necessarily indicative of the future financial position or future results of operations of the Company, or of the financial position or results of operations of the Company that would have actually occurred had the sales been consummated on the date indicated. The unaudited Pro Forma Condensed Consolidated Financial Statements should be read in conjunction with the historical financial statements and related notes of the Company previously filed with the Securities and Exchange Commission.
