PRO FORMA FINANCIAL DATA


   The following unaudited pro forma financial data reflects our historical
results as adjusted on a pro forma basis to give effect to our April 2004
offering of common units, together with the completion of the acquisition of
Spectrum Field Services, Inc. and the offering of 2,100,000 common units,
assuming that the underwriters do not exercise their over-allotment option to
purchase up to an additional 315,000 common units, as referred to in Item 5 of
this Form 8-K report. The unaudited pro forma balance sheet is prepared as
though these transactions occurred as of March 31, 2004. The unaudited pro forma
statement of operations for the year ended December 31, 2003 is prepared as
though these transactions occurred as of January 1, 2003. The unaudited pro
forma statement of operations for the three months ended March 31, 2004 is
prepared as though these transactions occurred as of January 1, 2004. The
acquisition and offering adjustments are described in the notes to the unaudited
pro forma financial data. The unaudited pro forma financial data and
accompanying notes should be read together with our "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and our and
Spectrum's historical financial statements and related notes included or
incorporated by reference in the prospectus supplement referred to in Item 5 of
this Form 8-K report. Because we will not complete the Alaska Pipeline
acquisition due to recent events, that acquisition is not included in these
unaudited pro forma financial statements.

   We accounted for the acquisition of Spectrum in the unaudited pro forma
financial statements using the purchase method in accordance with the guidance
of Statement of Financial Accounting Standards No. 141, "Business
Combinations." For purposes of developing the unaudited pro forma financial
information, we have allocated the purchase price to Spectrum's gas gathering
and transmission facilities based on fair market value.

   The unaudited pro forma financial statements presented are for informational
purposes only and are based upon available information and assumptions that we
believe are reasonable under the circumstances. You should not construe the
unaudited pro forma financial statements as indicative of the combined
financial position or results of operations that we and Spectrum would have
achieved had the transaction been consummated on the dates assumed. Moreover,
they do not purport to represent our and Spectrum's combined financial
position or results of operations for any future date or period or constitute
a representation that we will complete the Spectrum acquisition.

                         Atlas Pipeline Partners, L.P.
               Notes to Unaudited Pro Forma Financial Statements


a.   Reflects the net proceeds from our sale of 750,000 common units in April
     2004 and our general partner's 2% capital contribution in accordance with
     the terms of our partnership agreement.

b.   Reflects our purchase of 100% of the equity of Spectrum for $147 million,
     including estimated transaction costs. The acquisition will be financed
     by a $21.9 million preferred equity investment by Atlas America and
     Resource America in our operating subsidiary, the $25 million of net
     proceeds from our April 2004 common unit offering and a $100 million term
     loan under our new credit facility. We describe our new credit facility
     under "Business--New Credit Facility." Adjustments include the payment of
     $3.1 million of estimated financing costs which appear in the pro forma
     balance sheet as other assets.

c.   Reflects the adjustment to interest expense resulting from $100 million
     of borrowings under our new credit facility bearing an interest at the
     London Interbank Offered Rate, or LIBOR, plus 375 basis points, assumed
     to be 5.07% for the six months ended June 30, 2003 and 4.80% for the six
     months ended December 31, 2003. For the three months ended March 31,
     2004, the borrowings bear an interest rate of LIBOR plus 275 basis
     points, assumed to be 3.90%.

d.   Reflects the adjustment to depreciation expense based upon the cost of
     the acquired gas gathering and transmission facilities using depreciable
     lives ranging from 3 to 26.5 years and using the straight-line method.

e.   Reflects the amortization of deferred financing costs related to our new
     credit facility to finance the acquisition.

f.   Reflects the elimination of federal and state income taxes following the
     conversion of Spectrum, currently a C-corporation, to a limited liability
     company concurrent with its acquisition by us.

g.   Reflects the elimination of preferred stock dividends by Spectrum paid
     prior to our acquisition and payment of dividends on the preferred equity
     of our operating subsidiary.

h.   Reflects net proceeds in this offering of $72.1 million after offering
     costs of $4.1 million, assuming the issuance of 2.1 million common units
     at a price of $36.31 per unit (the average closing price from June 29,
     2004 to July 6, 2004), used to repurchase the $23 million preferred
     equity from Resource America and Atlas America (including a $1.1 million
     repurchase premium) and repay $49.1 million of borrowings under the $100
     million term loan.

i.   Reflects the 2% capital contribution from our general partner in
     accordance with the terms of our partnership agreement.

j.   Reflects the adjustment to interest expense resulting from the issuance
     of common units and the repayment of debt incurred to finance the
     Spectrum acquisition.

k.   Reflects a write-off of deferred financing costs in connection with a
     permanent $49.1 million repayment of the $100 million term loan.

l.   Reflects the adjustment to amortization as a result of the write-off of
     deferred financing costs due to the partial repayment of the $100 million
     term loan.

m.   Reflects the elimination of dividends paid on the preferred equity of our
     operating subsidiary as a result of its repurchase from the net proceeds
     of this offering.
