      AmeriVest Announces Performance and Operating Results for
                          First Quarter 2004

    DENVER--(BUSINESS WIRE)--May 5, 2004--AmeriVest Properties Inc.
(AMEX: AMV) reported results today for the first quarter ended March
31, 2004. Funds From Operations (FFO) for the first quarter of 2004
were $1,877,696 or $0.11 per diluted share, compared with $1,785,612,
or $0.16 per diluted share, for the same period in 2003. The Company
reported a net loss for the quarter of $375,011, or $0.02 per share,
compared with net income of $404,964, or $0.04 per share, for the
prior year period. See the Summary Financial Information for a
reconciliation of FFO and FFO per share from net (loss)/income and
(loss)/earnings per share, the most directly comparable GAAP measures.
    Revenues for the first quarter of 2004 increased 47% over the
prior year period primarily due to the Company's continued growth,
consisting of the inclusion of the operations from the Southwest Gas
Building for a full quarter in 2004 versus a partial quarter in 2003,
the late-2003 acquisitions (Financial Plaza, Scottsdale Norte and
Greenhill Park) for a full quarter in 2004, and the March 2004
Camelback Lakes acquisition for a partial month.
    Property operating expenses increased by 74% from 2003 to 2004
because of these transactions as well as increases in property taxes
and utility costs, which were previously discussed in the Company's
2003 year-end earnings release. Additionally, the Company added
regional operating management personnel in the Phoenix and Dallas
markets during the latter half of 2003 and in the Denver market in the
first quarter of 2004. Management believes it is important to the
Company's strategy to have experienced property management personnel
in its local markets; the regional offices are positioned to absorb
management of existing properties and future acquisitions within each
market.
    "Our first quarter financial results were generally in line with
our expectations," commented William Atkins, Chairman and Chief
Executive Officer of AmeriVest. "Compared to the fourth quarter of
2003, revenues were up 11%, operating margins were up 2%, general and
administrative expenses, as a percentage of revenue, were down almost
4% and FFO per diluted share was up 57%. In addition, our leasing
activity increased markedly during the quarter, with more than 50% of
the square footage leased during the quarter occurring in March. As
our markets continue to improve, we believe we are well positioned to
continue to make operating progress during the remainder of the year,"
continued Atkins.

    First Quarter Highlights

    --  On March 16, the Company acquired the Camelback Lakes office
        complex. Camelback Lakes is located in Phoenix, Arizona and
        contains approximately 203,000 square feet on 12.04 acres of
        land. The purchase price for Camelback Lakes was $31,980,000,
        which was paid with the proceeds from the Company's revolving
        lines of credit from Fleet National Bank.

    --  On March 16, the Company sold its Texas Bank Buildings for
        $4,100,000. The four properties are located in Clifton,
        Georgetown, Henderson and Mineral Wells, Texas and contain an
        aggregate of 60,095 square feet. This sale resulted in a gain
        of approximately $574,000. The operations of these properties,
        including the gain on sale, have been reclassified on the
        Company's consolidated statements of operations to
        discontinued operations for the current and comparable prior
        year period.

    --  During the first quarter, the Company entered into a contract
        to acquire an office property in metropolitan Dallas for
        $16,800,000. The property contains approximately 115,000
        square feet and the transaction is expected to close during
        May. The contract is subject to a number of contingencies and
        there is no assurance that this acquisition will occur.

    --  In March, the Company completed a 6,325,000 share common stock
        offering, which raised approximately $39,940,000 after
        underwriting commissions and offering expenses. RBC Capital
        Markets acted as the sole book-runner, with Ferris, Baker
        Watts, Incorporated, BB&T Capital Markets (a division of Scott
        & Stingfellow, Inc.), J.J.B. Hilliard, W.L. Lyons, Inc. and
        Stifel, Nicolaus & Company, Incorporated, having served as
        co-managers of the offering. The proceeds were used to repay
        the outstanding balance on the unsecured revolving line of
        credit with Fleet National Bank and a portion of the
        outstanding balance on the senior secured revolving line of
        credit, also with Fleet. The Company intends to use available
        amounts under these facilities to fund future property
        acquisitions and other working capital needs.

    --  In March, the Board of Directors declared a quarterly dividend
        of $0.13 per common share, which was paid on April 15, 2004,
        and represents our 31st consecutive quarterly dividend.

    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), to be an
appropriate measure of performance for an equity REIT, for the
reasons, and subject to the qualifications, specified in the paragraph
entitled "Non-GAAP Financial Measures" below. The above summary
financial information table reflects the reconciliation of FFO from
net income or (loss) and a comparison to earnings or (loss) per share,
the most directly comparable GAAP measure, for the periods presented.

    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 sales 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 operating performance of its properties without giving effect
to real estate depreciation and amortization, which assumes 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.
