                          ATLAS PIPELINE PARTNERS, L.P.
                        REPORTS RECORD OPERATING RESULTS
                      FOR THE YEAR ENDED DECEMBER 31, 2004

PHILADELPHIA, PA MARCH 11, 2005-ATLAS PIPELINE PARTNERS, L.P. (NYSE: APL) (THE
"PARTNERSHIP OR APL") reported revenues of $91.3 million for the year ended
December 31, 2004 compared to $15.7 million for the year ended December 30,
2003. Net income was $18.3 million or $2.60 per limited partner unit for the
year ended December 31, 2004 as compared to $9.6 million or $2.17 per limited
partner unit for the year ended December 31, 2003. Distributions to limited
partners declared during 2004 were $2.67 per common unit, compared to $2.39 per
common unit during 2003, a 12% increase.

The significant increases in revenues, distributions and net income from period
to period reflect improvements in transported volumes and transportation fees,
and the July 2004 acquisition of Tulsa, Oklahoma based Spectrum Field Services,
Inc.

Earnings before interest, taxes, depreciation and amortization ("EBITDA"), a
non-GAAP measure that is widely used by commercial banks, investment bankers,
rating agencies and investors in evaluating performance relative to peers and
pre-set performance standards, was $24.3 million for the year ended December 31,
2004 compared to $11.7 million for the year ended December 31, 2003. The
following table reconciles EBITDA, net of a one-time adjustment reflecting the
"Gain on arbitration settlement" in connection with the terminated acquisition
of Alaska Pipeline Company, to our net income for the years ended December 31,
2004 and 2003. (See Notes 1 and 2)

Due to the one-time nature of the "Gain on arbitration settlement", APL believes
Pro-forma net income, a non-GAAP measure, more clearly presents APL's true
operating performance during 2004. The following table reconciles net income to
pro-forma net income for the three and nine month periods ended September 30,
2004 and 2003. (See Note 2)

- ----------
Note 1. EBITDA represents net income before interest expense, income tax (not
        applicable to the Partnership), depreciation and amortization.
        Management of APL believes that EBITDA provides additional information
        with respect to APL's ability to meet its debt service, capital expense
        and working capital requirements. EBITDA is a commonly used measure of a
        business' ability to generate cash flow without consideration of its
        financing structure. This measure is widely used by commercial banks,
        investment bankers, rating agencies and investors in evaluating
        performance relative to peers and pre-set performance standards. It is
        also a financial measurement that, with certain negotiated adjustments,
        is reported to APL's banks to establish conformance with its financial
        covenants under its current credit facility. EBITDA is not a measure of
        financial performance under GAAP and, accordingly, should not be
        considered as a substitute for net income, or cash flows from operating
        activities, prepared in accordance with GAAP

Note 2. Pro-forma net income excludes "Gain on arbitration settlement" in
        connection with the terminated acquisition of Alaska Pipeline Company
        ("APC"). Due to its one-time nature, APL believes that net income
        excluding this gain more clearly presents APL's true operating
        performance during 2004. Pro-forma net income which excludes "Gain on
        arbitration settlement" is not a measure of financial performance under
        GAAP and, accordingly, should not be considered as a substitute for net
        income prepared in accordance with GAAP.

HIGHLIGHTS OF THE YEAR:

CORPORATE ACTIVITY

    o   In April 2004 we closed a follow-on equity offering of 750 thousand
        limited partner units at $36.00 per unit, resulting in net proceeds of
        approximately $25.4 million. In July 2004 we closed a follow-on equity
        offering of 2.1 million limited partner units at $34.76 per unit,
        resulting in net proceeds of approximately $69.5 million which was used
        for funding of the Spectrum acquisition.
    o   In May 2004, APL units were listed for trading on the New York Stock
        Exchange.
    o   In July 2004 we completed the acquisition of Spectrum Field Services,
        Inc. for approximately $142.0 million. In connection with this
        transaction, we established a $135.0 million term loan and credit
        facility, led by Wachovia Bank and Key Bank.
    o   In December 2004 we declared our 20th consecutive quarterly distribution
        in the amount of $.72 per unit - the largest distribution in our
        history. During 2004, total distributions of



        $2.67 per common unit were declared compared to $2.39 per unit during
        2003. (Subsequently, in March 2005 we declared a quarterly distribution
        of $.75 per unit.)
    o   At year-end 2004 SEMCO Energy, Inc. paid us $5.5 million to settle our
        claims relating to SEMCO's termination of the sale of Alaska Pipeline
        Company to us. Total costs incurred by us related to this transaction
        were approximately $4.0 million resulting in a "Gain on arbitration
        settlement" of $1.5 million.
    o   In March 2005, APL entered into an agreement to acquire the "Elk City
        system", another gathering and processing system in Oklahoma for total
        consideration of $190 million.

OPERATING ACTIVITY

    o   Total average daily throughput volumes for 2004 increased to an average
        of 109.8 million cubic feet per day, compared to an average of 52.5
        million per day during 2003.
    o   Currently (March 2005)
        o   Mid-continent inlet volumes are approximately 66 million cubic feet
            of gas per day
        o   Appalachian gathered volumes are approximately 53 million cubic feet
            of gas per day
        o   Total through-put volumes are approximately 119 million cubic feet
            of gas per day
    o   We connected 335 new wells to our Appalachian system during 2004
        compared to 270 during 2003.
    o   We connected 81 wells to our mid-continent system during the period from
        July 14, 2004 (the Spectrum acquisition date) to December 31, 2004,
        representing approximately 17 million cubic feet per day of new gathered
        gas.

ATLAS PIPELINE PARTNERS, L.P. is active in the gas gathering and processing
segment of the mid-stream natural gas industry. In Appalachia, it owns and
operates more than 1,400 miles of natural gas gathering pipelines in western
Pennsylvania, western New York and eastern Ohio to which more than 4,500 wells
are currently connected. APL currently gathers approximately 53 million cubic
feet ("mcf") of gas per day from these wells. In the Mid-Continent region of
southern Oklahoma and northern Texas, APL owns and operates approximately 1,900
miles of gas gathering pipeline serving approximately 600 wells. Currently, APL
transports approximately 66 million cubic feet of gas per day to its gas
processing facility in Velma, Oklahoma where natural gas liquids (NGL) are
removed. APL then sells the resulting gas and NGL and remits a portion of those
proceeds to the producer. In both Appalachia and the Mid-Continent, the fees
paid to APL are either a percentage of the gross selling price of the gas or NGL
or a fixed fee per mcf transported. For more information, visit our website at
