Agreement --------- In consideration of the premises and of the mutual covenants contained in this Agreement, the Parties agree as follows: 1. Purchase and Sale of Shares. 1.1 Purchase and Sale. Subject to the terms and conditions of this Agreement, Seller agrees to sell to Purchaser, and Purchaser agrees to purchase from Seller, the Plaza Interest. 1.2 Purchase Price. The purchase price (the "Purchase Price") for the Plaza Interest shall be the "Net Equity Value of Plaza" (defined as the fair market value of the balance sheet of Plaza as of March 31, 2001, set forth in Exhibit B), which equals $6,928,646, payable at "Closing" (hereafter defined) as follows: (a) Seller shall redeem Purchaser's LLC Interest for an amount equal to 9.639 percent of the "Net Equity Value of Seller" (defined as the fair market value of the balance sheet of Seller as of March 31, 2001, set forth in Exhibit C) which equals $705,934; and (b) AmeriVest shall deliver the balance of the Purchase Price in the form of 1,121,209 shares of the restricted common stock (the "Common Stock") of AmeriVest at the rate of $5.55 per share (the "AmeriVest Shares").

If the Net Operating Margin (as defined below) from Plaza for the year ending December 31, 2001 is not at least $581,400, then Seller shall pay to Purchaser an amount (the "Adjustment Amount") equal to 37.5 percent of the amount by which $581,400 exceeds the Net Operating Margin for the year ending December 31, 2001. For purposes of this Agreement, Net Operating Margin shall mean, for the year ending December 31, 2001, the net income for Plaza determined in accordance with generally accepted accounting principles ("GAAP") adjusted as follows: (a) increased by depreciation and amortization expenses, (b) increased by the amount by which the actual cash received during the period as rental payments exceeds the amount required to be accrued under GAAP as straight line rental income or decreased by the amount by which the actual cash received during the periods as rental payments is less than the amount required to be accrued under GAAP as straight line rental income, (c) reduced by the principal amortization on the Mortgage Loan (as defined in Section 2 below), and (d) reduced by lender reserves for capital expenditures required by the Mortgage (as defined in Section 2 below). On or before April 1, 2002, management of AmeriVest will provide a written determination of the Net Operating Margin to each of the directors of AmeriVest. At the request of a majority of the disinterested directors of AmeriVest, this determination of Net Operating Margin shall be submitted to AmeriVest's independent auditors (the "Auditors") for approval.

Within five business days of receiving the Objection Notice, Purchaser shall submit the determination and objection to the Auditors and request that the Auditors approve the determination or revise the determination within 10 business days after submission to the Auditors. A copy of the determination or approval of Net Operating Margin by the Auditors shall be delivered by Purchaser to Seller promptly upon receipt by Purchaser. The determination of Net Operating Margin as approved or revised by the Auditors (the "Auditors' Determination") shall be considered as final for purposes of this Section 1.3.
