Selected Financial Data

Company Overview

AmeriVest Properties Inc. is a real estate investment trust (REIT) which owns and operates commercial office buildings in selected markets catering to small and medium size businesses.  At September 30, 2005, AmeriVest owned 16 properties totaling approximately 2,451,000 square feet located in metropolitan Denver, Dallas, Phoenix and Indianapolis.  The Company is currently marketing for sale four of its properties, with approximately 716,000 cumulative square feet.

Strategy

We believe that office space for small to medium size businesses is a large and underserved market.  According to data compiled by the Office of Advocacy of the U.S. Small Business Administration, 89% of all U.S. businesses employed fewer than 20 employees.  As a result, we believe that many businesses have office space requirements of no more than 4,000 square feet.

Small to medium size businesses often have specific needs and limitations that are different from larger businesses.  For example, small and medium size businesses generally cannot afford large corporate staffs to manage their office leasing requirements.  These businesses have needs similar to larger firms, such as access to cutting edge technology, conference facilities, high quality telecommunications services and other amenities, but may not have a comparable budget.  Our strategy is to focus on providing an office product targeted to this large market and its unmet needs in a cost effective manner.  The key elements of our strategy include:

Provide a superior, consistent product - We provide amenities for the small and medium size businesses in our office properties that usually only larger companies would be able to obtain, such as conference rooms with the latest telecommunication and presentation equipment, high levels of common area and tenant finish, including well-designed, pre-built move-in ready space, and depending on the location, various other technology and service amenities relative to the needs of our targeted small business tenant.

Streamline the leasing process - Our leasing process is designed to meet the unique needs of a small to medium size tenant with limited real estate expertise, through our “no hassle” leasing philosophy which reduces the lease transaction time and cost for the tenant and us.

Provide a high level of service - With our deliberate focus on small and medium size businesses, we have developed a positive, service-oriented approach specifically tailored for our customer base.

Target select cities - We target cities that have excellent small business growth demographics, where we hope to build meaningful multi-property portfolios over both the near and long term.

As a result of our focused strategy, we believe that our properties provide office space that is particularly attractive for small and medium size businesses.  By executing on our strategy, we believe we have been able to maintain high occupancy rates while still maintaining strong rent per square foot trends in our core markets as compared to the general office market.

Non-GAAP Financial Measures

Funds from Operations -

Funds from Operations (FFO) is a non-GAAP financial measure.  We believe FFO, as defined by the Board of Governors of the National Association of Real Estate Investment Trusts (NAREIT) in the October 1999 White Paper (amended in April 2002), to be an appropriate measure of performance for an equity REIT, for reasons, and subject to the qualifications, specified in the paragraphs entitled “Non-GAAP Financial Measures” below.  The following table reflects the reconciliation of FFO from net loss and a comparison of FFO per share to loss per share, the most directly comparable GAAP measures:

	Three months ended
	9/30/05			6/30/05			3/31/05			12/31/04			9/30/04

Non-GAAP Financial Measures - Funds from Operations (FFO) is a non-GAAP financial measure.  FFO is defined as net income or loss, computed in accordance with generally accepted accounting principles (GAAP), excluding gains or losses from sale of properties, plus real estate related depreciation and amortization and after adjustments for unconsolidated partnerships and joint ventures.  We believe that FFO is helpful to investors as a measure of the performance of an equity REIT because it facilitates an understanding of the operations performance of its properties without giving effect to real estate depreciation and amortization, which assume that the value of real estate assets diminishes predictably over time.  Since real estate values have historically risen or fallen with market conditions, we believe that FFO provides a more meaningful and accurate indication of our performance.  We compute FFO in accordance with standards established by the Board of Governors of the National Association of Real Estate Investment Trusts (NAREIT), which may not be comparable to FFO reported by other REITs that do not define the term in accordance with the current NAREIT definition or that interpret the current NAREIT definition differently than we do.  FFO does not represent cash generated from operating activities determined by GAAP and should not be considered as an alternative to net income or loss (determined in accordance with GAAP) as an indication of our financial performance or to cash flows from operating activities (determined in accordance with GAAP) as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to make cash distributions.  FFO may include funds that may not be available for our management’s discretionary use due to requirements to conserve funds for capital expenditures, debt repayments property acquisitions and other commitments and uncertainties.

Same Store Property Net Operating Income - 

Net Operating Income (NOI) is a non-GAAP financial measure.  NOI is defined as rental revenues less property operating expenses.  Because historically, acquisitions from year to year have had a material impact on the Company’s results of operations, we rely on Same Store NOI for assessing property performance.  We also believe Same Store property NOI is a valuable means of comparing period-to-period property performance.  The following is a reconciliation of Same Store Property NOI to Loss From Continuing Operations (amounts in thousands):

	Three months ended September 30,						Nine months ended September 30,
	2005			2004			2005			2004
Same Store Property NOI	$	4,413		$	3,945		$	9,547		$	8,791
