ITEM 1. DESCRIPTION OF BUSINESS

         THE FOLLOWING DISCUSSION CONTAINS FORWARD-LOOKING STATEMENTS REGARDING
EVENTS AND FINANCIAL TRENDS WHICH MAY AFFECT OUR FUTURE OPERATING RESULTS AND
FINANCIAL POSITION. SUCH STATEMENTS ARE SUBJECT TO RISKS AND UNCERTAINTIES THAT
COULD CAUSE OUR ACTUAL RESULTS AND FINANCIAL POSITION TO DIFFER MATERIALLY FROM
THOSE ANTICIPATED IN THESE FORWARD-LOOKING STATEMENTS. THESE FACTORS INCLUDE
FLUCTUATIONS IN THE MARKET FOR NATURAL GAS FROM WHICH OUR REVENUES ARE DERIVED,
PRODUCTION DECLINES FROM WELLS SERVICED BY OUR GATHERING SYSTEMS, REDUCED
DRILLING FOR NEW WELLS IN OUR SERVICE AREAS AND OUR NEED FOR ADDITIONAL CAPITAL
TO EXPAND OUR GATHERING SYSTEMS.

GENERAL

          We are a Delaware limited partnership with common units traded on the
New York Stock Exchange under the symbol "APL." We own and operate approximately
3,280 miles of natural gas pipeline gathering systems through our operating
partnership and its operating subsidiaries. Our pipeline systems currently
consist of approximately 1,380 miles of intrastate gathering systems located in
the Appalachian Basin in eastern Ohio, western New York and western Pennsylvania
and 1,900 miles of intrastate gathering systems in southern Oklahoma and
northern Texas. We have expanded our gathering systems both through extensions
to connect new natural gas supplies and through acquisitions. In addition, we
own and operate a natural gas processing facility in Velma, Oklahoma. Our
gathering systems currently serve approximately 5,100 wells with an average
daily throughput for the years ended December 31, 2004, 2003 and 2002 of 109.8
million cubic feet, or mmcf, 52.5 mmcf and 50.4 mmcf of natural gas,
respectively. Our gathering systems provide a means through which well owners
and operators can transport the natural gas produced by their wells to public
utility pipelines for delivery to customers. To a lesser extent, our gathering
systems transport natural gas directly to customers.

         We originally acquired the gathering systems of Atlas America, Inc.
(NASDAQ:ATLS) and its affiliates, all of which are subsidiaries of Resource
America, Inc. (NASDAQ: REXI), when we commenced operations in January 2000. We
refer to the Resource America energy subsidiaries with which we have contractual
relationships, including Atlas America, collectively as "Atlas America," unless
specifically stated otherwise. Atlas America and its affiliates sponsor limited
and general partnerships to raise funds from investors to explore for natural
gas, and produce natural gas and, to a lesser extent, oil from locations in
eastern Ohio, western New York and western Pennsylvania. Our Appalachian Basin
gathering systems are connected to 4,500 of those wells. Atlas America drilled
and connected 335 wells to our Appalachian Basin gathering systems during the
year ended December 31, 2004, 270 wells during the year ended December 31, 2003
and 195 wells during the year ended December 31, 2002.

         We are party to an omnibus agreement with Atlas America that is
intended to maximize the use and expansion of our gathering systems and the
amount of natural gas they transport. Among other things, the omnibus agreement
requires Atlas America to install required flow lines and connect wells it
operates that are located within 2,500 feet of one of our gathering systems.

         We are also party to natural gas gathering agreements with Atlas
America under which it pays us gathering fees generally equal to a percentage,
generally 16%, of the gross or weighted average sales price of the natural gas
we transport subject, in certain cases, to minimum prices of $.35 or $.40 per
thousand cubic feet, or mcf. Our business, therefore, depends in large part on
the prices at which the natural gas we transport is sold. Due to the volatility
of natural gas prices, our gross revenues can vary materially from period to
period.

                                       -3-

         Acquisition of Spectrum Field Services, Inc. In July 2004, we acquired
Spectrum Field Services, Inc., or Spectrum, which changed its name to Atlas
Pipeline Mid-Continent, LLC. ("APLMC"), for approximately $142.4 million,
including transaction costs and taxes due as a result of the transaction. This
acquisition significantly increased our size and diversifies the natural gas
supply basins in which we operate and the natural gas midstream services we
provide to our customers. Spectrum was a natural gas gathering and processing
company headquartered in Tulsa, Oklahoma. APLMC's business includes gathering
natural gas from oil and gas wells and processing this raw natural gas into
merchantable natural gas, or residue gas, by extracting natural gas liquids, or
NGLs, and removing impurities. APLMC sells natural gas to purchasers at the
tailgate of our gas plant located in Velma, Oklahoma, and sells its NGLs to Koch
Hydrocarbon at the plant under an agreement that is renewed monthly. APLMC's
principal assets consist of a gas processing plant in Velma, Oklahoma and
approximately 1,100 miles of active and 760 miles of inactive natural gas
gathering pipelines in south central Oklahoma and north Texas. APLMC has more
than 650 separate gas purchase contracts. Of these, approximately 75% (by
volume) are percentage of proceeds, or POP, contracts. Under its POP purchasing
arrangements, APLMC purchases natural gas at the wellhead, processes the natural
gas by extracting NGLs and removing impurities and sells the residue gas and
NGLs at market-based prices, remitting to producers a contractually-determined
percentage of the sale proceeds. Unlike "keep whole" contracts, which require
the processor to bear the economic risk (called the processing margin risk) that
the aggregate proceeds from the sale of the processed natural gas and NGLs could
be less than the amount that the processor paid for the unprocessed natural gas,
POP contracts protect the processor against processing margin risk. The
remaining 20% of APLMC's purchase and gathering contracts are fixed fee, under
which APLMC receives a fee for gathering, compressing, treating and processing
natural gas. During the year ended December 31, 2004, APLMC processed an average
of 56.4 million cubic feet, or mmcf, per day of natural gas and produced an
average of 5,799 bbls per day of NGLs. The majority of APLMC's natural gas
supply is from relatively long-lived, mid-continent casinghead gas production.

         We financed the Spectrum acquisition, including approximately $4.2
million of transaction costs, as follows:

         o  borrowing $100.0 million under the term loan portion of our $135.0
            million senior secured term loan and revolving credit facility
            administered by Wachovia Bank, National Association;

         o  using the $20.0 million of net proceeds received from the sale to
            Resource America and Atlas America of preferred units in our
            operating subsidiary; and

         o  using $22.4 million of the net proceeds from our April 2004 common
            unit offering.

         We used a portion of the net proceeds of our July 2004 offering to
repay $40.0 million of the borrowings under our new credit facility and to
repurchase for $20.4 million the preferred units issued to Resource America and
Atlas America.

         Public Offerings. In April and July 2004, we completed public offerings
of 750,000 and 2,100,000 common units of limited partner interest. The net
proceeds after underwriting discounts and commissions were approximately $25.2
million and $67.5 million, respectively. Our general partner simultaneously
contributed $535,000 and $1.5 million to us in order to maintain its 2% general
partner interest in us.

         Settlement of Alaska Pipeline Company Arbitration. In September 2003,
we entered into an agreement with SEMCO Energy, Inc. to purchase all of the
stock of Alaska Pipeline Company. In order to complete the acquisition, we
needed the approval of the Regulatory Commission of Alaska. The Regulatory
Commission initially approved the transaction, but on June 4, 2004 it vacated
its order of approval based upon a motion for clarification or reconsideration
filed by SEMCO. On July 1, 2004, SEMCO sent us a notice purporting to terminate
the transaction. We pursued our remedies under the acquisition agreement. In
connection with the acquisition, subsequent termination, and settlement of the
legal action, we incurred costs of approximately $4.0 million in the year ended
December 31, 2004. On December 30, 2004, we entered into a settlement agreement
with SEMCO settling all issues and matters related to SEMCO's termination of the
sale of Alaska Pipeline Company to us and SEMCO paid us $5.5 million. We show
this settlement, net of expenses on our Consolidated Statement of Income as Gain
on arbitration settlement, net.

                                       -4-

         Distribution Increases. In February, 2004, we paid a quarterly cash
distribution of $0.625 per common unit (an annualized rate of $2.50 per common
unit). In December 2004, the managing board of our general partner approved an
increase in the quarterly cash distribution to $0.72 per common unit (an
annualized rate of $2.88 per common unit). There can be no assurance we will be
able to generate sufficient available cash to make distributions at this level.

APPALACHIAN OPERATIONS

         Public utility pipelines charge transportation fees to the entity
having title to the natural gas being transported, typically the well owner, an
intermediate purchaser such as a natural gas distribution company, or a final
purchaser. We do not have title to the natural gas gathered and delivered by us
and, accordingly, do not pay transportation fees charged by public utility
pipelines. We do not transport any oil produced by wells connected to our
gathering systems.

         We are party to an omnibus agreement with Atlas America, Inc. that is
intended to maximize the use and expansion of our gathering systems and the
amount of natural gas they transport. Among other things, the omnibus agreement
requires Atlas America to install required flow lines and connect wells it
operates that are located within 2,500 feet of one of our gathering systems.

         We are also party to natural gas gathering agreements with Atlas
America under which it pays us gathering fees generally equal to a percentage,
generally 16%, of the gross or weighted average sales price of the natural gas
we transport subject, in most cases, to minimum prices of $0.35 or $0.40 per
thousand cubic feet, or mcf. Our business, therefore, depends in large part on
the prices at which the natural gas we transport is sold. Due to the volatility
of natural gas prices, our gross revenues can vary materially from period to
period. During the year ended December 31, 2004, we received gathering fees
averaging $0.96 per mcf, while during the years ended December 31, 2003 and
2002, our average gathering fees were $0.82 and $0.58 per mcf, respectively.

MID-CONTINENT OPERATIONS

Natural Gas and NGL Supply and Sales

         ChevronTexaco is APLMC's largest supplier of natural gas under a
contract that has a life-of-lease or 10-year term expiring in 2010 with a
year-to-year renewal provision. The 236 wells under ChevronTexaco's contract
supply approximately 10.0 million cubic feet, (mmcf) per day to the APLMC
system. APLMC retains a weighted average of 47% of the NGL revenues and a
weighted average of 10% of the residue gas revenues from sales of this gas.
APLMC's remaining gas contracts have varying terms: the latest expiration date
is 2008, with a few scheduled to terminate in 2005. The term of others has
expired, but the producers continue to sell the gas under the year-to-year
renewal provisions.

         In February, 2004, Spectrum entered into a contract with Zinke & Trumbo
to gather and process natural gas from a new development northwest of Duncan,
Oklahoma. In March 2004, Spectrum completed a 29-mile, large-diameter high
pressure trunkline to connect this new gas supply. The Duncan line is currently
delivering nine mmcf of natural gas per day.

                                       -5-
<PAGE>
         APLMC sells its NGL production to Koch Hydrocarbons at the Velma gas
plant under an agreement that is renewed monthly. Spectrum has the right to
elect (on a monthly basis) whether the NGLs are sold into the Mont Belvieu or
Conway markets. NGLs are priced at the average monthly Oil Price Information
Service price for the selected market. In addition, this agreement provides for
a fee which is based upon the Houston Ship Channel spot-gas price and fluctuates
monthly from $0.0125 and $0.015 per gallon for deliveries to Mont Belvieu.

         APLMC also has a transportation and fractionation contract with Koch
Hydrocarbons, which expires in January 2006. Condensate is collected at both the
Velma gas plant and in the Velma gathering system and sold for APLMC's account
to SemGroup, L.P. under an agreement with a primary term which expired on
November 30, 2004 and continues on a month-to-month basis.

         APLMC sells natural gas to purchasers at the tailgate of the Velma gas
plant. During the year ended December 31, 2004 and 2003, ONEOK Energy Marketing
and Trading accounted for 31% and 85%, respectively, of Spectrum's residue
natural gas sales and Tenaska Marketing Ventures accounted for 12% and 15% of
such sales, respectively. APLMC currently sells the majority of its residue
natural gas at the average of ONEOK Gas Transmission and Southern Star Central
first-of-month indices as published in Inside FERC, with the remainder being
sold on a NYMEX basis, less a fixed basis differential.

Natural Gas and NGL Hedging

         APLMC also uses hedges to limit its exposure to changing natural gas
and NGL prices. These hedges include floating-for-fixed swaps and collars. In a
floating-for-fixed swap, APLMC sells future production to the counterparty at a
fixed price and agrees to purchase production from the counterparty at a price
that will be established on the date of hedge settlement by reference to a
specified index price. In a collar, APLMC purchases a put option for specified
production quantities while simultaneously selling a call option on the same
amount of production. These hedges cover periods of up to two years from the
date of the hedge. To insure that these financial instruments will be used
solely for hedging price risks and not for speculative purposes, APLMC has
established a hedging committee to review its hedges for compliance with its
hedging policies and procedures. In addition, APLMC does not enter into a hedge
where it cannot offset the hedge with physical residue natural gas or NGL sales.

         The portion of residue natural gas and NGLs that APLMC hedges and the
manner in which it is hedged changes from time to time. As of December 31, 2004,
APLMC's hedging position for future months through December 31, 2006 for its
residue and NGL production was approximately as follows:

         o  43% was hedged under floating-for-fixed swaps;

         o  10% was hedged with collars; and

         o  47% was not hedged and was subject to market-based pricing.

            APLMC recognizes gains and losses from the settlement of its hedges
in revenue when it sells the associated physical residue natural gas or NGLs.
Any gain or loss realized as a result of hedging is substantially offset in the
market when APLMC sells the physical residue natural gas or NGLs. All of APLMC's
hedges are characterized as cash flow hedges as defined in Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Accounting." APLMC determines gains or losses on open and closed
hedging transactions as the difference between the hedge price and the physical
price. This mark-to-market uses daily closing NYMEX prices when applicable and
an internally-generated algorithm for hedged commodities that are not traded on
a market.

CREDIT FACILITIES

         Concurrently with the completion of the Spectrum acquisition, in July
2004, we entered into a $135.0 million senior secured term loan and revolving
credit facility administered by Wachovia Bank that replaced our $20.0 million
facility. The facility originally included a $35.0 million four year revolving
line of credit and a $100.0 million five year term loan. Upon the completion of
our July 2004 public offering, we repaid $40.0 million of the $100.0 million
term loan we had borrowed in order to complete the acquisition of Spectrum, and
in December 2004, we repaid an additional $15.0 million by borrowing $10.0
million on our revolving line of credit. In August 2004 and December 2004, the
revolving credit portion of the facility was increased to $75.0 million and
$90.0 million, respectively. Up to $5.0 million of the facility may be used for
standby letters of credit. Borrowings under the facility are secured by a lien
on and security interest in all of our property and that of our subsidiaries and
by the guaranty of each of our subsidiaries. The credit facility bears interest
at one of two rates, elected at our option:

         o  the base rate plus the applicable margin; or

         o  the adjusted LIBOR plus the applicable margin.

         The base rate for any day equals the higher of the federal funds rate
plus 1/2 of 1% or the Wachovia Bank prime rate. The applicable margin for the
revolving line of credit is as follows:

         o  where our leverage ratio, that is, the ratio of our debt to our
            earnings before interest, taxes depreciation and amortization, or
            EBITDA, is less than or equal to 2.5, the applicable margin is 1.00%
            for base rate loans and 2.00% for LIBOR loans;

         o  where our leverage ratio is greater than 2.5 but less than or equal
            to 3.0, the applicable margin is 1.25% for base rate loans and 2.25%
            for LIBOR loans;

         o  where our leverage ratio is greater than 3.0 but less than or equal
            to 3.5, the applicable margin is 1.75% for base rate loans and 2.75%
            for LIBOR loans; and

         o  where our leverage ratio is greater than 3.5, the applicable margin
            is 2.25% for base rate loans and 3.25% for LIBOR loans.

         The applicable margin for the term loan is 0.75% higher for both base
rate loans and LIBOR loans.

         The credit facility requires us to maintain a ratio of funded debt to
EBITDA of not more than 4.0 to 1.0, reducing to 3.5 to 1.0 on June 30, 2005, and
an interest coverage ratio of not less than 3.0 to 1.0. In addition, we will be
required to prepay the term loan with the net proceeds of any asset sales or
issuances of debt. With respect to any issuances of equity, we will be required
to repay the term loan from the proceeds of such issuances to the extent our
ratio of funded debt to EBITDA exceeds 3.5 to 1.0. We are required to pay down
$560,000 in principal on the outstanding balance of the term loan quarterly. Any
prepayments of principal with proceeds from asset or equity sales that it makes
will be credited pro rata against this repayment obligation.

         The credit agreement contains covenants customary for loans of this
size, including restrictions on incurring additional debt and making material
acquisitions, and a prohibition on paying distributions to our unitholders if an
event of default occurs. The events which constitute an event of default are
also customary for loans of this size, including payment defaults, breaches of
our representations or covenants contained in the credit agreement, adverse
judgments against us in excess of a specified amount, and a change of control of
our general partner.

RECENT DEVELOPMENTS

         On March 8, 2005, we entered into an agreement with LG PL, LLC, a Texas
limited liability company, and La Grange Acquisition, L.P., a Texas limited
partnership, both subsidiaries of Energy Transfer Partners, L.P. (NYSE: ETP), to
acquire all of the outstanding equity interests in ETC Oklahoma Pipeline, Ltd.,
a Texas limited partnership. ETC Oklahoma Pipeline's principal assets include
more than 315 miles of natural gas pipelines located in the Anadarko Basin in
western Oklahoma, a natural gas processing facility in Elk City, Oklahoma and a
gas treatment plant in Prentiss, Oklahoma. The total consideration will be
approximately $190 million in cash. The purchase price is subject to
post-closing adjustment based on gas imbalances, certain prepaid costs and
expenses and capital expenditures, and title defects, if any. Consummation of
the acquisition is conditioned on the receipt of various approvals, including
Hart-Scott-Rodino Act approval or early termination of the application waiting
period, and other customary closing conditions.

         We have received a commitment from Wachovia Bank, National Association
and Bank of America, N.A. to arrange the syndication of a $270 million loan
facility. The facility will be comprised of a $225 million 5-year revolving loan
and a $45 million 5-year term loan. Up to $10.0 million of the facility may be
used for standby letters of credit. Borrowings under the facility will be
secured by a lien on and security interest in all of our property and that of
our subsidiaries and by the guaranty of each of our subsidiaries. The loan
proceeds will be used to refinance our existing $135 million facility and to
finance the acquisition of ETC Oklahoma Pipeline.

COMPETITION

         Appalachian Basin. Our Appalachian Basin operations do not encounter
direct competition in their service areas since Atlas America controls the
majority of the drillable acreage in each area. However, because our Appalachian
Basin operations principally serve wells drilled by Atlas America, we are
affected by competitive factors affecting Atlas America's ability to obtain
properties and drill wells, which affects our ability to expand our gathering
systems and to maintain or increase the volume of natural gas we transport and,
thus, our transportation revenues. Atlas America also may encounter competition
in obtaining drilling services from third-party providers. Any competition it
encounters could delay Atlas America in drilling wells for its sponsored
partnerships, and thus delay the connection of wells to our gathering systems.
These delays would reduce the volume of gas we otherwise would have transported,
thus reducing our potential transportation revenues.

         As our omnibus agreement with Atlas America generally requires it to
connect wells it operates to our system, we do not expect any direct competition
in connecting wells drilled and operated by Atlas America in the future. In
addition, we occasionally connect wells operated by third parties. During 2004,
we connected no such wells.

         During 2004, we encountered competition in acquiring gas gathering
systems owned by third parties. In several instances we submitted bids in
auction situations and in direct negotiations for the acquisition of existing
gas gathering systems. Except for our bid for Spectrum, in each case we were
either outbid by others or were unwilling to meet the sellers' expectations and,
as a result, were unsuccessful in acquiring those systems. In the future, we
expect to encounter equal if not greater competition for gathering system
acquisitions because, as gas prices increase, the economic attractiveness of
owning gathering systems increases.

         Mid-Continent. In its southern Oklahoma and north Texas service area,
APLMC competes for the acquisition of well connections with several other
gathering/servicing operations. These operations include plants operated by Duke
Energy Field Services, ONEOK Field Services and Enogex. We believe that the
principal factors upon which competition for new well connections is based are:

         o    the price received by an operator for its production after
              deduction of allocable charges, principally the use of the natural
              gas to operate compressors; and

         o    responsiveness to a well operator's needs.

         We believe that our electric compressors operate more efficiently than
the gas-operated compressors used by our competitors. As a result, we believe
that we can operate as or more cost-effectively than our competitors. We also
believe that our relationships with operators connected to our system are good.
However, if APLMC cannot compete successfully, it may be unable to obtain new
well connections and, possibly, could lose wells already connected to its
system. [See "Risk Factors--APLMC's success depends upon its ability to
continually find and contract for new sources of natural gas supply."]

REGULATION

         Federal Regulation. Under the Natural Gas Act, the Federal Energy
Regulatory Commission regulates various aspects of the operations of any
"natural gas company," including the transportation of natural gas, rates and
charges, construction of new facilities, extension or abandonment of services
and facilities, the acquisition and disposition of facilities, reporting
requirements, and similar matters. However, the Natural Gas Act definition of a
"natural gas company" requires that the company be engaged in the transportation
of natural gas in interstate commerce, or the sale in interstate commerce of
natural gas for resale. Since we believe that each of our individual gathering
systems perform primarily gathering functions, we believe that we are not
subject to regulation under the Natural Gas Act. If we were determined to be a
natural gas company, our operations would become regulated under the Natural Gas
Act. We believe the expenses associated with seeking certificates of authority
for construction, service and abandonment, establishing rates and a tariff for
our gas gathering activities, and meeting the detailed regulatory accounting and
reporting requirements under the Natural Gas Act would substantially increase
our operating costs and would adversely affect our profitability, thereby
reducing our ability to make distributions to unitholders.

                                      -9-
<PAGE>
         State Regulation. Our operations are subject to regulation by the
Public Utility Commission of Ohio, the New York Public Service Commission and
the Pennsylvania Public Utilities Commission. APLMC's operations are subject to
regulation by the Oklahoma Corporation Commission and the Texas Railroad
Commission.

         In Ohio, a producer or gatherer of natural gas may file an application
seeking exemption from regulation as a public utility. We have been granted an
exemption by the Public Utility Commission of Ohio for our Ohio facilities. The
New York Public Service Commission imposes traditional public utility regulation
on the transportation of natural gas by companies subject to its regulation.
This regulation includes rates, services and siting authority for the
construction of certain facilities. Our gas gathering operations currently are
not subject to regulation by the New York Public Service Commission. Our
operations in Pennsylvania currently are not subject to the Pennsylvania Public
Utility Commission's regulatory authority since they do not provide service to
the public generally and, accordingly, do not constitute the operation of a
public utility. In the event the New York and Pennsylvania authorities seek to
regulate our operations, we believe that our operating costs could increase and
our transportation fees could be adversely affected, thereby reducing our net
revenues and ability to make distributions to unitholders.

         APLMC is subject to regulation by the Oklahoma Corporation Commission
and the Texas Railroad Commission. The state of Oklahoma has adopted a
complaint-based statute that allows the Oklahoma Corporation Commission to
remedy discriminatory rates for providing gathering service where the parties
are unable to agree. In a similar way, the Texas Railroad Commission sponsors a
complaint procedure for resolving grievances about natural gas gathering access
and rate discrimination. No such complaint has been made against APLMC to date
in either Oklahoma or Texas.

         Environmental and Safety Regulation. Under the Comprehensive
Environmental Response, Compensation and Liability Act, or CERCLA, the Toxic
Substances Control Act, the Resource Conservation and Recovery Act, or RCRA, the
Clean Air Act, the Clean Water Act and other federal and state laws relating to
discharges of materials into the environment or otherwise protective of the
environment, owners and operators of natural gas pipelines and associated
storage and processing facilities can be liable, sometimes on a strict, joint
and several basis, for fines, penalties investigatory and remedial costs, and
compliance costs including capital expenditures with respect to pollution caused
by the pipelines and associated facilities. Moreover, the owners' and operators'
liability can extend to pollution costs that arose from activities or incidents
that occurred prior to such owners' or operators' acquisition of the pipelines
and associated facilities, even in circumstances where the current owner or
operator did not cause or contribute to the pollution.

         We own, lease or operate properties that in the past have been subject
to pipeline gathering and/or oil and gas processing activities. Although we have
used operating and disposal practices that were standard in the industry at the
time, hydrocarbons and wastes may have been disposed of or released on or under
these properties or on or under other locations where such materials have been
taken for disposal. A number of these properties have been operated by previous
owners or operators whose environmental activities were not under our control.
These properties and the hydrocarbons and wastes disposed thereon may be subject
to CERCLA, RCRA, and analogous state laws. Under such laws, we could be required
to remove or remediate previously disposed hydrocarbons, hazardous substances,
or wastes or property contamination, or to perform investigatory and remedial
actions to prevent future contamination.

                                      -10-
<PAGE>
         Natural gas pipelines are also subject to safety regulation,
administered by state regulators, under the Natural Gas Pipeline Safety Act of
1968 and the Pipeline Safety Act of 1992 which, among other things, dictate the
type of pipeline, quality of pipeline, depth, methods of welding and other
construction-related standards and subjects pipelines to regular inspections.
The state public utility regulators in our service areas have either adopted the
federal standards or promulgated their own safety requirements consistent with
federal regulations. Although we believe that our gathering systems comply in
all material respects with applicable environmental and safety regulations,
risks of substantial costs and liabilities are inherent in pipeline operations,
and we cannot assure you that we will not incur these costs and liabilities.
Moreover, it is possible that other developments, such as increasingly rigorous
environmental laws, regulations and enforcement policies, and claims for damages
to property or persons resulting from our operations, could result in
substantial costs and liabilities to us.

         We are also subject to the requirements of the Occupational Safety and
Health Act, or OSHA, and comparable state statutes. We believe that our
operations comply in all material respects with OSHA requirements, including
general industry standards, record keeping, hazard communication requirements
and monitoring of occupational exposure and other regulated substances.

         We have not expended and do not anticipate that we will be required in
the near future to expend, amounts that are material in relation to our revenues
by reason of environmental and safety laws. However, we cannot predict
legislative or regulatory developments or the costs of compliance with those
developments. In general, however, we anticipate that new laws, regulations or
policies will increase our operating costs and impose additional capital
expenditure requirements on us.

TAX TREATMENT OF PUBLICLY TRADED PARTNERSHIPS UNDER THE INTERNAL REVENUE CODE

         The Internal Revenue Code of 1986, as amended, imposes certain
limitations on the current deductibility of losses attributable to investments
in publicly traded partnerships and treats certain publicly traded partnerships
as corporations for federal income tax purposes. The following discussion
briefly describes certain aspects of the Code that apply to individuals who are
citizens or residents of the United States without commenting on all of the
federal income tax matters affecting us or the holders of our units, and is
qualified in its entirety by reference to the Code. UNITHOLDERS ARE URGED TO
CONSULT THEIR OWN TAX ADVISOR ABOUT THE FEDERAL, STATE, LOCAL AND FOREIGN TAX
CONSEQUENCES TO THEM OF AN INVESTMENT IN US.

         Characterization for Tax Purposes. The Code treats a publicly traded
partnership as a corporation for federal income tax purposes unless, for each
taxable year, 90% or more of its gross income consists of qualifying income.
Qualifying income includes interest, dividends, real property rents, gains from
the sale or disposition of real property, income and gains derived from the
exploration, development, mining or production, processing, refining,
transportation (including pipelines transporting gas, oil or products thereof),
or the marketing of any mineral or natural resource (including fertilizer,
geothermal energy and timber), and gain from the sale or disposition of capital
assets that produce such income. Because we are engaged primarily in the natural
gas pipeline transportation business, we believe that 90% or more of our gross
income has been qualifying income. If this continues to be true and no
subsequent legislation amends that provision, we will continue to be classified
as a partnership and not as a corporation for federal income tax purposes.

         Passive Activity Loss Rules. The Code provides that an individual,
estate, trust, or personal service corporation generally may not deduct losses
from passive activities, to the extent they exceed income from all such passive
activities, against other (active) income. Income that may not be offset by
passive activity losses includes not only salary and active business income, but
also portfolio income such as interest, dividends or royalties or gain from the
sale of property that produces portfolio income. Credits from passive activities
are also limited to the tax attributable to any income from passive activities.
The passive activity loss rules are applied after other applicable limitations
on deductions, such as the at-risk rules and basis limitations.

                                      -11-
<PAGE>
         Under the Code, net income from publicly traded partnerships is not
treated as passive income for purposes of the passive lose rule, but is treated
as non-passive income. Net losses and credits attributable to an interest in a
publicly traded partnership may not be used to offset a partner's other income.
Thus, a unitholder's proportionate share of our net losses may be used to offset
only partnership net income from our trade or business in succeeding taxable
years or, upon a complete disposition of a unitholder's interest in us to an
unrelated person in a fully taxable transaction, may be used to offset gain
recognized upon the disposition, and then against all other income of the
unitholder. In effect, net losses are suspended and carried forward indefinitely
until utilized to offset net income of the partnership from its trade or
business or allowed upon the complete disposition to an unrelated person in a
fully taxable transaction of the unitholder's interest in the partnership. A
unitholder's share of partnership net income may not be offset by passive
activity losses generated by other passive activities. In addition, a
unitholder's proportionate share of our portfolio income, including portfolio
income arising from the investment of our working capital, is not treated as
income from a passive activity and may not be offset by such unitholder's share
of net losses of the partnership.

         Deductibility of Interest Expense. The Code generally provides that
investment interest expense is deductible only to the extent of a non-corporate
taxpayer's net investment income. In general, net investment income for purposes
of this limitation includes gross income from property held for investment, gain
attributable to the disposition of the property held for investment (except for
net capital gains for which the taxpayer has elected to be taxed at special
capital gains rates) and portfolio income (determined pursuant to the passive
lose rules) reduced by certain expenses (other than interest) which are directly
connected with the production of such income. Property subject to the passive
loss rules is not treated as property held for investment. However, the IRS has
issued a Notice which provides that net income from a publicly traded
partnership (not otherwise treated as a corporation) may be included in net
investment income for purposes of the limitation on the deductibility of
investment interest. A unitholder's investment income attributable to its
interest in us will include both its allocable share of our portfolio income and
trade or business income. A unitholder's investment interest expense will
include its allocable share of our interest expense attributable to portfolio
investments.

         Unrelated Business Taxable Income. Certain entities otherwise exempt
from federal income taxes (such as individual retirement accounts, pension plans
and charitable organizations) are nevertheless subject to federal income tax on
net unrelated business taxable income and each such entity must file a tax
return for each year in which it has more than $1,000 of gross income from
unrelated business activities. We believe that substantially all of our gross
income will be treated as derived from an unrelated trade or business and
taxable to such entities. The tax-exempt entity's share of our deductions
directly connected with carrying on such unrelated trade or business are allowed
in computing the entity's taxable unrelated business income.

         State Tax Treatment. During 2004, we owned property or conducted
business in the states of Pennsylvania, New York, Oklahoma, Ohio and Texas. A
unitholder is required to file state income tax returns and to pay applicable
state income taxes in the states and may be subject to penalties for failure to
comply with such requirements. None of these states have required that we
withhold a percentage of income attributable to our operations within the state
for unitholders who are non-residents of the state. In the event that one or
more of them do require withholding in the future, (which may be greater or less
than a particular unitholder's income tax liability to the state), such
withholding would generally not relieve the non-resident unitholder from the
obligation to file a state income tax return.

         Depreciation. Upon our formation in 2000, we elected fifteen-year 150%
declining-balance depreciation for tax purposes. Unitholders, however, will
continue to offset partnership income with individual unitholder depreciation
pursuant to our Section 754 election. Each unitholder's tax situation will
differ depending upon the price paid and when units were purchased. Furthermore,
sale of units will result in a portion of gain (if any) being taxable as
ordinary income through recapture of previous deductions for depreciation.

EMPLOYEES

         As is commonly the case with publicly traded limited partnerships, we
do not directly employ any of the persons responsible for our management or
operations. In general, employees of Atlas America and its parent company,
Resource America, Inc., manage the gathering systems and operate our business.
Affiliates of our general partner will conduct business and activities of their
own in which we will have no economic interest. If these separate activities are
significantly greater than our activities, there could be material competition
between us, our general partner and affiliates of our general partner for the
time and effort of the officers and employees who provide services to our
general partner. The officers of our general partner who provide services to us
are not required to work full time on our affairs. These officers may devote
significant time to the affairs of our general partner's affiliates and be
compensated by these affiliates for the services rendered to them. There may be
significant conflicts between us and affiliates of our general partner regarding
the availability of these officers to manage us.

                                  RISK FACTORS

         Limited partner interests are inherently different from the capital
stock of a corporation, although many of the business risks we encounter are
similar to those that would be faced by a corporation engaged in a similar
business. If any of the following risks actually occurs, our business, financial
condition or results of operations could be materially adversely affected. In
that case, the trading price of our securities could decline and investors may
lose some or all of their investment.

General

         Interest rate increases will increase our interest costs. See Item 7A,
"Quantitative and Qualitative Disclosures about Market Risk." This could have
material adverse effects on us, including reduction of our net income.

Our cash distributions are not assured and may fluctuate with our performance.

         The amounts of cash that we generate may not be sufficient to pay the
minimum quarterly distributions established in our partnership agreement or any
other level of distributions. The actual amounts of cash we generate will depend
upon numerous factors relating to our business which may be beyond our control,
including:

         o the demand for and price of natural gas and NGLs;

         o the volume of natural gas we transport;

                                      -13-
<PAGE>
         o  the availability of local, intrastate and interstate transportation
            systems;

         o  continued development of wells for connection to our gathering
            systems;

         o  the expenses we incur in providing our gathering services;

         o  the cost of acquisitions and capital improvements;

         o  our issuance of equity securities;

         o  required principal and interest payments on our debt;

         o  fluctuations in working capital;

         o  prevailing economic conditions;

         o  fuel conservation measures;

         o  alternate fuel requirements;

         o  government regulation and taxation; and

         o  technical advances in fuel economy and energy generation devices.

         Our ability to make cash distributions depends primarily on our cash
flow. Cash distributions do not depend directly on our profitability, which is
affected by non-cash items. Therefore, cash distributions may be made during
periods when we record losses and may not be made during periods when we record
profits.

The failure of Atlas America to perform its obligations under the natural gas
gathering agreements may adversely affect our revenues.

         A majority of our Appalachian revenues currently consist of the fees we
receive under the master natural gas gathering agreement and other
transportation agreements we have with Atlas America and its affiliates. While
Atlas America receives gathering fees from the well owners, it is contractually
obligated to pay our fees even if the gathering fees paid to it by well owners
are less than the fees it must pay us. Our cash flow could be materially
adversely affected if Atlas America failed to discharge its obligations to us.

The amount of natural gas we transport will decline over time unless new wells
are connected to our gathering systems.

         Production of natural gas from a well generally declines over time
until the well can no longer economically produce natural gas and is plugged and
abandoned. Failure to connect new wells to our gathering systems could,
therefore, result in the amount of natural gas we transport reducing
substantially over time and could, upon exhaustion of the current wells, cause
us to abandon one or more of our gathering systems and, possibly, cease
operations. As a consequence, our revenues and, thus, our ability to make
distributions to unitholders would be materially adversely affected.

         We entered into the omnibus agreement with Atlas America to, among
other things, increase the number of natural gas wells connected to our
gathering systems. However, well connections resulting from that agreement
depend principally upon the success of Atlas America in sponsoring drilling
investment partnerships and completing wells for these partnerships in areas
where our gathering systems are located. If Atlas America cannot or does not
continue to organize these partnerships, if the amount of money raised by these
partnerships decreases, or if the number of wells actually drilled and completed
as commercial producing wells decreases, our revenues and ability to make cash
distributions will be materially adversely affected.

                                      -14-
<PAGE>
APLMCs success depends upon its ability to continually find and contract for new
sources of natural gas supply.

         As with our Appalachian Basin operations, in order for APLMC to
maintain or increase throughput levels on its gathering systems and at its
processing plant, it must continually contract for new natural gas supplies. The
primary factors affecting APLMC's ability to connect new supplies of natural gas
to its gathering systems include its success in contracting for existing wells
that are not committed to other systems and the level of drilling activity near
its gathering systems. Unlike our Appalachian Basin operations, none of the
drillers or operators in APLMC's service area are our affiliates.

         Fluctuations in energy prices can greatly affect production rates and
investments by third parties in the development of new oil and natural gas
reserves. Drilling activity generally decreases as oil and natural gas prices
decrease. We have no control over the level of drilling activity in APLMC's
operating areas, the amount of reserves underlying wells that connect to its
system and the rate at which production from a well will decline, sometimes
referred to as the "decline rate." In addition, APLMC has no control over
producers or their production decisions, which are affected by, among other
things, prevailing and projected energy prices, demand for hydrocarbons, the
level of reserves, geological considerations, governmental regulation and the
availability and cost of capital.

The amount of natural gas we transport may be reduced if the public utility
pipelines to which we deliver gas cannot or will not accept the gas.

         Our gathering systems principally serve as intermediate transportation
facilities between sales lines from wells connected to our systems and the
public utility pipelines to which we deliver natural gas. If one or more of
these public utility pipelines has service interruptions, capacity limitations
or otherwise does not accept the natural gas we transport, and we cannot arrange
for delivery to other public utility pipelines, local distribution companies or
end users, the amount of natural gas we transport may be reduced. Since our
revenues depend upon the volumes of natural gas we transport, this could result
in a material reduction in our revenues.

Our Mid-Continent operations depend on certain key producers for their supply of
natural gas; the loss of any of these key producers could reduce our revenues.

         During 2003, ChevronTexaco, Inc., Chesapeake Operating, Inc. and Mack
Energy Co. supplied Spectrum with approximately 40% of its natural gas supply.
During 2004 those producers, together with Zinke & Trumbo, Inc. supplied
Spectrum with approximately 44% of its natural gas supply. If these producers
reduce the volumes of natural gas that they supply to us, our revenues would be
reduced unless we obtain comparable supplies of natural gas from other
producers.

APLMC is exposed to the credit risk of its customers and an increase in
nonpayment could lead to material losses.

         During the years ended December 31, 2004 and 2003, ONEOK Energy
Marketing and Trading accounted for approximately 31% and 85%, respectively of
APLMC's residue natural gas sales from APLMC's Velma Plant and Tenaska Marketing
Ventures accounted for approximately 12% and 15%, respectively of such sales.
Koch Hydrocarbons, L.P. accounted for all of Spectrum's NGL sales. Should any of
these customers fail to fulfill their payment obligations, become insolvent or
file a petition in bankruptcy, we would incur material losses.

                                      -15-

We have no previous experience either in APLMC's service area or in operating a
natural gas processing plant.

         APLMC's pipelines are located in southern Oklahoma and northern Texas,
areas in which we have had no previous operations. In addition, APLMC operates a
natural gas processing plant, a business with which we have had no previous
operating experience. As a result, we will depend upon the experience, knowledge
and business relationships that have been developed by APLMC's senior
management, who are employees of our general partner, to operate APLMC
successfully. The loss of the services of one or more members of APLMC's senior
management and, in particular, Robert R. Firth, APLMC's President and David D.
Hall, APLMC's Chief Financial Officer, could limit APLMC's growth or its ability
to maintain its current level of operations.

We may be unable to successfully integrate APLMC's operations with our
operations and to realize all of the anticipated benefits of the acquisition.

         We acquired APLMC in July 2004 and are currently in the process of
integrating its operations with ours. The integration of two companies that
previously have operated independently can be a complex, costly and
time-consuming process. The difficulties of combining the companies include,
among other things:

         o  operating a significantly larger combined company;

         o  the necessity of coordinating geographically disparate
            organizations, systems and facilities;

         o  integrating personnel with diverse business backgrounds and
            organizational cultures; and

         o  consolidating corporate and administrative functions.

         Combining the companies may be made particularly difficult by the large
size of APLMC as compared to us and the geographic separation of its operations
and our Appalachian Basin operations. The process of combining the companies
could cause an interruption in our business and, possibly, the loss of key
personnel. The diversion of management's attention and any delays or
difficulties encountered in connection with the integration of the two companies
could harm our business, results of operations, financial condition or
prospects.

Governmental regulation of our pipelines could increase our operating costs,
decrease our revenues, or both.

         Currently our gathering of natural gas from wells is exempt from
regulation under the Natural Gas Act. However, the implementation of new laws or
policies could subject us to regulation by the Federal Energy Regulatory
Commission under the Natural Gas Act. We expect that any such regulation would
increase our costs, decrease our revenues, or both.

         Gas gathering operations are subject to regulation at the state level.
Matters subject to regulation include rates, service and safety. We have been
granted an exemption from regulation as a public utility in Ohio. Presently, our
rates are not regulated in New York and Pennsylvania. The state of Oklahoma has
adopted a complaint-based statute that allows the Oklahoma Corporation
Commission to remedy discriminatory rates for providing gathering service where
the parties are unable to agree. In a similar way, the Texas Railroad Commission
sponsors a complaint procedure for resolving grievances about natural gas
gathering access and rate discrimination. The gathering fees Spectrum charges
are deemed just and reasonable under Oklahoma and Texas law unless challenged by
a complaint. Should a complaint be filed or regulation by either of the
commissions become more active, our revenues could decrease.

         Changes in state regulations, or our status under these regulations
that subject us to further regulation, could increase our operating costs or
require material capital expenditures.

Litigation or governmental regulation relating to environmental protection and
operational safety may result in substantial costs and liabilities.

         Our operations are subject to federal and state environmental laws
under which owners of natural gas pipelines can be liable for clean-up costs and
fines in connection with any pollution caused by their pipelines. We may also be
held liable for clean-up costs resulting from pollution which occurred before
our acquisition of the gathering systems. In addition, we are subject to federal
and state safety laws that dictate the type of pipeline, quality of pipe
protection, depth, methods of welding and other construction-related standards.
Any violation of environmental, construction or safety laws could impose
substantial liabilities and costs on us.

         We are also subject to the requirements of OSHA, and comparable state
statutes. Any violation of OSHA could impose substantial costs on us.

         We cannot predict whether or in what form any new legislation or
regulatory requirements might be enacted or adopted, nor can we predict our
costs of compliance. In general, we expect that new regulations would increase
our operating costs and, possibly, require us to obtain additional capital to
pay for improvements or other compliance action necessitated by those
regulations.

We may not be able to fully execute our growth strategy.

         Our strategy contemplates substantial growth through both the
acquisition of other gathering systems and the development of our existing
system. Typically, we have paid for system development in cash and have made
acquisitions either for cash or a combination of cash and common units. As a
result, limitations on our access to capital or on the market for our common
units will impair our ability to execute our growth strategy. In addition, our
strategy of growth through acquisitions involves numerous risks, including:

         o  we may not be able to identify suitable acquisition candidates;

         o  we may not be able to make acquisitions on economically acceptable
            terms;

         o  our costs in seeking to make acquisitions may be material, even if
            we cannot complete any acquisition we have pursued;

         o  irrespective of estimates at the time we make an acquisition, the
            acquisition may prove to be dilutive to earnings and operating
            surplus; and

         o  we may encounter difficulties in integrating operations and systems.

A decline in natural gas prices could adversely affect our revenues.

         Our gathering fees are generally equal to a percentage of either the
gross or weighted average sales price of the natural gas we transport, although
in some cases we receive a flat fee per mcf of gas transported. Our income
therefore depends upon the prices at which the natural gas we transport is sold.
Historically, the price of natural gas has been volatile; as a result, our
income may vary widely from period to period.

Gathering system operations are subject to operational hazards and unforeseen
interruptions.

         The operations of our gathering systems are subject to hazards and
unforeseen interruptions, including natural disasters, adverse weather,
accidents or other events beyond our control. A casualty occurrence might result
in injury and extensive property or environmental damage. Our insurance coverage
may not be sufficient for any casualty loss we may incur.

ITEM 2. DESCRIPTION OF PROPERTIES

         As of December 31, 2004 our principal facilities in Appalachia include
approximately 1,440 miles of 2 to 12 inch diameter pipeline and 56 compressors,
of which four are leased. Our principal facilities in the Mid-Continent area
consist of a natural gas processing plant, approximately 1,900 miles of active
and inactive 2-to-42 inch diameter pipeline, and 18 compressors, of which seven
are leased. Substantially all of our gathering systems are constructed within
rights-of-way granted by property owners named in the appropriate land records.
In a few cases, property for gathering system purposes was purchased in fee. All
of our compressor stations are located on property owned in fee or on property
under long-term leases.

PIPELINE CHARACTERISTICS

         We set forth in the following table the volumes of the natural gas we
transported, in mcfs, in the years ended December 31, 2004, 2003 and 2002.

</TABLE>
         Of the approximately 4,500 wells currently connected to our Appalachian
gathering systems, approximately 4,400 are owned by Atlas America or its
affiliates or by investment partnerships managed or operated by Atlas America or
its affiliates, with the remainder being owned or managed by third parties. We
have agreements with Atlas America and its affiliates relating to the connection
of future wells owned or controlled by them to our gathering systems and the
transportation fees we will charge. These wells are the principal producers of
gas transported by our gathering systems and we anticipate that wells controlled
by Atlas America will continue in the future to be the principal producers into
our gathering systems. As of December 31, 2004, Atlas America and its affiliates
controlled leases on developed properties in the operational area of our
gathering systems totaling approximately 196,800 gross acres. In addition, Atlas
America and its affiliates control leases on approximately 226,706 undeveloped
gross acres of land. During the year ended December 31, 2004, Atlas America and
its affiliates drilled and connected 335 wells to our gathering systems as
compared to 270 and 214 wells during the years ended December 31, 2003 and 2002,
respectively.

         Our Appalachian gathering systems are generally constructed with 2, 4,
6, 8 and 12 inch cathodically protected and wrapped steel pipe and are generally
buried 36 inches below the ground. Pipelines constructed in this manner
typically are expected to last at least 50 years from the date of construction.
For the years ended December 31, 2004, 2003 and 2002, the cost of operating the
gathering systems, excluding depreciation, was approximately $2.3 million, $2.4
million and $2.1 million, respectively. We do not believe that there are any
significant geographic limitations upon our ability to expand in the areas
served by our gathering systems.

                                      -18-

         APLMC has a Gas Plant and Gathering System located in Velma, Oklahoma.
The Velma Gas Plant has inlet gas processing and treating capacity of 100 MMCFD
(100 million cubic feet per day) and residue gas compression capacity of
approximately 58 MMCFD. The plant receives natural gas from the upstream Velma
Gathering System and delivers residue gas to two pipelines at the tailgate of
the plant and NGL liquids to a liquids pipeline.

         The Velma Gas Plant is a twin-expander cryogenic facility with natural
gas throughput capacity of approximately 100MMCFD. Key components of the plant
are: an amine treating system (for C02 and H2S); an acid gas disposal well; a
12,000 HP electric inlet compression, a 5,000 HP residue electric compression.
The Velma Gathering System is comprised of approximately 1,100 miles of active
and 760 miles of inactive pipeline ranging in size from 2 inches to 42 inches in
diameter and 18 field booster sites providing 14,417 horsepower. It currently
gathers 60 MMCFD of natural gas, which is delivered to the Velma Gas Plant, from
approximately 580 receipt points owned by producers and other gatherers.

         Our revenues are determined primarily by the amount of natural gas
flowing through our gathering systems and the price received for this natural
gas. Our ability to increase the flow of natural gas through our gathering
systems and to offset the natural decline of the production already connected to
our gathering systems will be determined primarily by our ability to connect new
wells to our gathering systems and to acquire additional gathering assets.

         Our property or rights-of-way are subject to encumbrances, restrictions
and other imperfections, although these imperfections have not interfered, and
our general partner does not expect that they will materially interfere with the
conduct of our business. In many instances, lands over which rights-of-way have
been obtained are subject to prior liens which have not been subordinated to the
right-of-way grants. In a few instances, our rights-of-way are revocable at the
election of the land owners. In some cases, not all of the owners named in the
appropriate land records have joined in the right-of-way grants, but in
substantially all such cases signatures of the owners of majority interests have
been obtained. Substantially all permits have been obtained from public
authorities to cross over or under, or to lay facilities in or along, water
courses, county roads, municipal streets, and state highways, where necessary,
although in some instances these permits are revocable at the election of the
grantor. Substantially all permits have also been obtained from railroad
companies to cross over or under lands or rights-of-way, many of which are also
revocable at the grantor's election.

         Certain of our rights to lay and maintain pipelines are derived from
recorded gas well leases, which wells are currently in production; however, the
leases are subject to termination if the wells cease to produce. In some of
these cases, the right to maintain existing pipelines continues in perpetuity,
even if the well associated with the lease ceases to be productive. In addition,
because many of these leases affect wells at the end of lines, these
rights-of-way will not be used for any other purpose once the related wells
cease to produce.

          We rent 8,000 square feet of office space in Tulsa, Oklahoma through
July 2005 for our Mid-Continent operations.

ITEM 3. LEGAL PROCEEDINGS

         On March 9, 2004, the Oklahoma Tax Commission ("OTC") filed a petition
against Spectrum alleging that Spectrum underpaid gross production taxes
beginning in June 2000. The OTC is seeking a settlement of $5.0 million plus
interest and penalties. We plan on defending ourselves vigorously. In addition,
under the terms of the Spectrum purchase agreement, $14.0 million has been
placed in escrow to cover the costs of any adverse settlement resulting from the
petition and other indemnification obligations of the purchase agreement.

         Settlement of Alaska Pipeline Company Arbitration. In September 2003,
we entered into an agreement with SEMCO Energy, Inc. to purchase all of the
stock of Alaska Pipeline Company. In order to complete the acquisition, we
needed the approval of the Regulatory Commission of Alaska. The Regulatory
Commission initially approved the transaction, but on June 4, 2004 it vacated
its order of approval based upon a motion for clarification or reconsideration
filed by SEMCO. On July 1, 2004, SEMCO sent us a notice purporting to terminate
the transaction. We pursued our remedies under the acquisition agreement. In
connection with the acquisition, subsequent termination, and settlement of the
legal action, we incurred costs of approximately $4.0 million in the year ended
December 31, 2004. On December 30, 2004, we entered into a settlement agreement
with SEMCO settling all issues and matters related to SEMCO's termination of the
sale of Alaska Pipeline Company to us and SEMCO paid us $5.5 million.

         We are not, nor are any of our gathering systems, subject to any other
pending legal proceedings.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         No matters were submitted to a vote of the common unitholders during
the fourth quarter of the year ended December 31, 2004.

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED UNITHOLDER MATTERS

         Our common units are listed on the New York Stock Exchange under the
symbol "APL." As of December 31, 2004, 73 holders of record held our common
units. In connection with our initial public offering, we also issued 1,641,026
subordinated units, discussed below, all of which are held by our general
partner. There is no established public trading market for the subordinated
units.

         The following table sets forth the range of high and low sales prices
of our common units and distributions per unit on our common and subordinated
units for the last two years.

         Our partnership agreement generally requires us to distribute available
cash 98% to the limited partners and 2% to our general partner except for our
general partner's incentive distribution rights. These rights require
distributions of increased percentages of available cash to the general partner
as distributions to limited partners exceed specified minimums, as follows:

         Available cash generally means for any of our quarters, all cash on
hand at the end of the quarter less cash reserves that our general partner
determines are appropriate to provide for our operating costs, including
potential acquisitions, and to provide funds for distributions to the partners
for any one or more of the next four quarters.

Our partnership agreement allocates distributions to limited partners in
accordance with their relative number of units except that, during the
subordination period, distributions to subordinated units are subordinated to
the receipt by the common units of a minimum quarterly distribution of $.42 per
common unit, plus any unpaid minimum quarterly distribution amounts from prior
periods. The subordination period terminated on January 1, 2005. Upon expiration
of the subordination period, the subordinated units converted into common units
on a one-for-one basis, and will now participate pro rata with the other common
units in distributions of our available cash.

         We make distributions of available cash to unitholders regardless of
whether the amount distributed is less than the minimum quarterly distribution.

         For information concerning units authorized for issuance under our
long-term incentive plan, see Notes 8 and 15 of our Notes to Consolidated
Financial Statements.

ITEM 6. SELECTED FINANCIAL DATA

         The following selected financial data should be read together with our
consolidated financial statements, the notes to our consolidated financial
statements and "Management's Discussion and Analysis of Financial Condition and
Results of Operations" in Item 7 in this report. We have derived the selected
financial data set forth below for each of the years ended December 31, 2004,
2003 and 2002 and at December 31, 2004 and 2003 from our consolidated financial
statements appearing elsewhere in this report, which have been audited by Grant
Thornton LLP, independent accountants. We derived the financial data as of
December 31, 2002, 2001 and 2000 and for the years ended December 31, 2001
and 2000 from our financial statements, which were audited by Grant Thornton
LLP, and are not included in this report. The financial data for the period
ended December 31, 2000 is for the period beginning with the inception of our
operations on January 28, 2000 through December 31, 2000; and, accordingly, we
deem January 28, 2000 to be the commencement of our operations and we refer to
the period from that date through December 31, 2000 as the year ended December
31, 2000.

         EBITDA means income before net interest expense, income taxes and
depreciation and amortization and other non-cash items such as compensation
expenses associated with unit issuances to employees of the general partner and
directors. EBITDA is not intended to represent cash flow and does not represent
the measure of cash available for distribution. Our method of computing EBITDA
may not be the same method used to compute similar measures reported by other
companies, or EBITDA may be computed differently by us in different contexts
(i.e., public reporting versus computation under financing agreements).

         Certain items excluded from EBITDA are significant components in
understanding and assessing a company's financial performance, such as a
company's cost of capital and its tax structure, as well as historic costs of
depreciable assets. We have included information concerning EBITDA because
EBITDA provides investors and management with additional information as to our
ability to pay our fixed charges and is presented solely as a supplemental
financial measure. EBITDA should not be considered as an alternative to, or more
meaningful than, net income or cash flow as determined in accordance with
generally accepted accounting principles or as an indicator of our operating
performance or liquidity. The table below shows our EBITDA and reconciles it to
our net income.

         The following information is provided to assist in understanding our
financial condition and results of operations. This discussion should be read in
conjunction with our consolidated financial statements and related notes
appearing elsewhere in this report.

GENERAL

         Our principal business objective is to generate income for distribution
to our unitholders.

         Our business is conducted in the midstream natural gas industry and we
are active in the Appalachian and Mid-Continent areas of the United States,
specifically, Pennsylvania, Ohio, New York, Oklahoma and Texas.

         In Appalachia, we gather approximately 53 million cubic feet of gas per
day through our pipeline system from more than 5,200 wells for delivery to a
variety of customers on major intra- or interstate pipeline systems and a
limited number of direct end-users. This transported gas is primarily controlled
by Atlas America, Inc., the parent company of our general partner.

                                      -23-
<PAGE>
         Our Mid-Continent operations began in July 2004 upon our acquisition of
Spectrum Field Services, Inc. In the Mid-Continent, we purchase approximately 56
million cubic feet of gas per day under more than 650 separate gas purchase
contracts. This gas is then transported to our Velma, Oklahoma gas processing
facility where the natural gas liquids, or NGLs, along with various impurities
are removed. The remaining pipeline quality gas is then delivered into a major
intrastate pipeline system where it is sold at market prices. The NGLs are
similarly delivered into a separate major intrastate pipeline system where they
are also sold for a price determined by the value of the actual components of
that liquid stream, for example, ethane, butane, propane etc.

FEE ARRANGEMENTS:

         In Appalachia, substantially all of the gas we transport is for Atlas
America under a POP contract where we earn a fee equal to a percentage,
generally 16% of the selling price of the gas subject, in most cases to a
minimum of $.35 or $.40 per mcf. Since our inception in January 2000, our
transportation fee has always exceeded this minimum. The balance of the
Appalachian gas we transport is for third party operators generally under fee
contracts.

         Our revenues in Mid-Continent are determined primarily by the fees
APLMC earns from the following two types of arrangements:

         Fee-Based Contracts. We receive a set fee for gathering and processing
raw natural gas. Our revenue is a function of the volume of gas that we gather
and process and is not directly dependent on the value of that gas.

         Percent of Proceeds or POP Contracts: These contracts provide for us to
retain a negotiated percentage of the residue natural gas and NGLs resulting
from our gathering and processing operations with the remainder being remitted
to the producer. In this situation, we and the producer are directly dependent
on the volume of the commodity and its value - we own a percentage of that
commodity and are directly subject to its ultimate market value.

         Unlike many of our competitors, we have no keep-whole contracts where
the producer has the right to receive 100% of the thermal value of its produced
raw natural gas based on the value of the processed and delivered pipeline
quality residue natural gas. This type of contract exposes the processing
company to frac-spread risk - the difference between the value of the NGL
extracted from processing and the thermal value equivalent of the residue
natural gas.

         In the Mid-Continent, approximately 75% of our volumes and revenues are
derived from POP contracts. The percentage of the proceeds that we retain is
negotiated and can vary greatly depending on a variety of factors and
circumstances.

         Based on historical trends, we generally expect NGL prices to follow
changes in crude oil prices over the long term, which we believe will in large
part be determined by the level of production from major crude oil exporting
countries and the demand generated by growth in the world economy. We believe
that future natural gas prices will be influenced by supply deliverability, the
severity of winter and summer weather and the level of United States economic
growth. The number of active oil and gas rigs has increased in the past year,
mainly due to recent significant increases in natural gas prices, which could
result in sustained increases in drilling activity during 2004. However, energy
market uncertainty could negatively impact North American drilling activity in
the short term. Lower drilling levels over a sustained period would have a
negative effect on natural gas volumes gathered and processed.

                                      -24-
<PAGE>
         We closely monitor the risks associated with these commodity price
changes on our future operations and, where appropriate, use various commodity
instruments such as natural gas, crude oil and NGL contracts to hedge a portion
of the value of our assets and operations from such price risks. We do not
realize the full impact of commodity price changes because some of our sales
volumes were previously hedged at prices different than actual market prices.
The recognition in our Consolidated Statements of Income of the cumulative
changes in the fair value of these hedge instruments reduced our results of
operations by $259,000 in the year ended December 31, 2004. See "Item 7A.
Quantitative and Qualitative Disclosure About Market Risk". The remaining term
over which we are currently hedging our exposure to the variability of future
cash flows is through the end of 2006.

SPECTRUM ACQUISITION

         On July 16, 2004, we acquired Spectrum Field Services, Inc., which we
refer to as Spectrum, Mid-Continent or APLMC, for approximately $142.4 million,
including the payment of taxes due as a result of the transaction. This
acquisition significantly increased our size and diversified the natural gas
supply basins in which we operate and the natural gas midstream services we
provide to our customers. We expect the Spectrum acquisition to be accretive to
our cash distributions per common unit.

         We financed the Spectrum acquisition, including approximately $4.2
million of transaction costs, as follows:

         o  borrowing $100.0 million under the term loan portion of our new
            $135.0 million senior secured term loan and revolving credit
            facility administered by Wachovia Bank, National Association;

         o  using the $20.0 million of net proceeds received from the sale to
            Resource America, Inc. and Atlas America, Inc. of preferred units in
            our operating subsidiary Atlas Pipeline Operating Partnership, L.P.;
            and

         o  using $22.4 million of the net proceeds from our April 2004 common
            unit offering.

         In July 2004, we completed a public offering of 2,100,000 common units
of limited partner interest whose net proceeds after underwriting discounts and
commissions and costs were $67.5 million. We used a portion of the net proceeds
of this offering to repay $40.0 million of the borrowings under our new credit
facility and to repurchase the preferred units from Resource America and Atlas
America.

         The acquisition of Spectrum significantly changed our financial
position and results of operations. At December 31, 2004, we had an available
borrowing capacity $77.8 million. We intend to finance our growth with a
combination of long-term debt and equity to maintain our financial flexibility
to fund future opportunities.

SETTLEMENT OF ALASKA PIPELINE COMPANY ARBITRATION

         In September 2003, we entered into an agreement with SEMCO Energy, Inc.
to purchase all of the stock of Alaska Pipeline Company. In order to complete
the acquisition, we needed the approval of the Regulatory Commission of Alaska.
The Regulatory Commission initially approved the transaction, but on June 4,
2004 it vacated its order of approval based upon a motion for clarification or
reconsideration filed by SEMCO. On July 1, 2004, SEMCO sent Atlas Pipeline a
notice purporting to terminate the transaction. We pursued our remedies under
the acquisition agreement. On December 30, 2004, we entered into a settlement
agreement with SEMCO settling all issues and matters related to SEMCO's
termination of the sale of Alaska Pipeline Company to us and SEMCO paid us $5.5
million. In connection with the termination and settlement of the legal action,
we incurred costs of approximately $1.4 million. In addition, we also incurred
$2.6 million of costs associated with the acquisition of SEMCO. These proceeds
and costs are shown as "Gain on arbitration settlement, net" on our consolidated
statement of income for the year ended December 31, 2004.

                                      -25-
<PAGE>

RECENT DEVELOPMENTS

         On March 8, 2005, we entered into an agreement with LG PL, LLC, a Texas
limited liability company, and La Grange Acquisition, L.P., a Texas limited
partnership, both subsidiaries of Energy Transfer Partners, L.P. (NYSE: ETP), to
acquire all of the outstanding equity interests in ETC Oklahoma Pipeline, Ltd.,
a Texas limited partnership. ETC Oklahoma Pipeline's principal assets include
more than 315 miles of natural gas pipelines located in the Anadarko Basin in
western Oklahoma, a natural gas processing facility in Elk City, Oklahoma and a
gas treatment plant in Prentiss, Oklahoma. The total consideration will be
approximately $190 million in cash. The purchase price is subject to
post-closing adjustment based on gas imbalances, certain prepaid costs and
expenses and capital expenditures, and title defects, if any. Consummation of
the acquisition is conditioned on the receipt of various approvals, including
Hart-Scott-Rodino Act approval or early termination of the application waiting
period, and other customary closing conditions.

         We have received a commitment from Wachovia Bank, National Association
and Bank of America, N.A. to arrange the syndication of a $270 million loan
facility. The facility will be comprised of a $225 million 5-year revolving loan
and a $45 million 5-year term loan. Up to $10.0 million of the facility may be
used for standby letters of credit. Borrowings under the facility will be
secured by a lien on and security interest in all of our property and that of
our subsidiaries and by the guaranty of each of our subsidiaries. The loan
proceeds will be used to refinance our existing $135 million facility and to
finance the acquisition of ETC Oklahoma Pipeline.

RESULTS OF OPERATIONS

         In the years ended December 31, 2004, 2003 and 2002, our principal
revenues came from the operation of our pipeline gathering systems which
transport, process and compress natural gas. Two variables which affect our
transportation revenues are:

         o  the volumes of natural gas transported by us which, in turn, depend
            upon the number of wells connected to our gathering system, the
            amount of natural gas they produce, and the demand for that natural
            gas; and

         o  the transportation fees paid to us which, in turn, depend upon the
            price of the natural gas we transport, which itself are a function
            of the relevant supply and demand in the mid-Atlantic and
            northeastern areas of the United States.

         We set forth the average volumes we transported, our average gross
margin rate per mcf and average transportation rates per Mcf and revenues
received by us for the periods indicated in the following table:

Year Ended December 31, 2004 Compared to Year Ended December 31, 2003

         Revenues. Our natural gas and liquid revenues are associated with our
acquisition of Spectrum on July 16, 2004. These revenues reflect five and one
half months of operations in the current year. We anticipate that these revenues
will increase in 2005.

         Our transportation and compression revenues increased to $18.8 million
in the year ended December 31, 2004 from $15.7 million in the year ended
December 31, 2003. This increase of $3.1 million (20%) consisted of an increase
in the average transportation rate paid to us ($2.8 million) and an increase in
the volumes of natural gas we transported ($357,000).

         Our transportation rate was $.96 per Mcf in the year ended December 31,
2004 as compared to $.82 per Mcf in the year ended December 31, 2003, an
increase of $.14 per Mcf (17%). During the year ended December 31, 2004, natural
gas prices increased significantly over the year ended December 31, 2003. Since
our transportation rates are generally at fixed percentages of the sale prices
of the natural gas we transport, the higher prices resulted in an increase in
our average transportation rate.

         Our average daily throughput volumes in Appalachia were 53,343 Mcfs in
the year ended December 31, 2004 as compared to 52,472 Mcfs in the year ended
December 31, 2003, an increase of 871 mcfs (2%). The increase in the average
daily throughput volume resulted principally from volumes associated with new
wells added to our pipeline system; we turned on-line 335 and 270 wells in the
years ended December 31, 2004 and 2003, respectively. These increases were
partially offset by the natural decline in production volumes from existing
wells connected to our gathering systems.

                                      -27-
<PAGE>
         Our gain on arbitration settlement, net is the result of a December 30,
2004 settlement agreement with SEMCO settling all issues and matters related to
SEMCO's termination of the sale of Alaska Pipeline Company to us. SEMCO paid us
$5.5 million, which is shown net of $1.4 million of arbitration costs and $2.6
million of acquisition costs.

         Costs and Expenses. Our natural gas and NGL and plant operating
expenses are associated with our acquisition of Spectrum on July 16, 2004. These
expenses reflect five and one half months of operations in the current year. We
anticipate that these expenses will increase in 2005.

         Our transportation and compression expenses decreased to $2.3 million
in the year ended December 31, 2004 as compared to $2.4 million in the year
ended December 31, 2003, a decrease of $161,000 (7%). Our average cost per Mcf
of transportation and compression decreased to $.12 in the year ended December
31, 2004 as compared to $.13 in the year ended December 31, 2003, a decrease of
$.01 (8%). This decrease resulted primarily from a decrease in compressor
expenses due to our purchase of several compressors in the year 2003 which we
had previously leased.

         Our general and administrative expenses increased to $4.6 million in
the year ended December 31, 2004 as compared to $1.7 million in the year ended
December 31, 2003, an increase of $2.9 million (180%). This increase includes
the following:

            o  $1.1 million of general and administrative expenses associated
               with the operations of Spectrum which we acquired on July 16,
               2004;

            o  $821,000 for the expensing of phantom units issued under our
               Long-Term Incentive Plan and the related distributions on those
               units;

            o  $473,000 in increased allocations of compensation and benefits
               from Atlas America and its affiliates due to an increase in
               management time spent on our acquisition and public offerings;
               and

            o  $349,000 from costs associated with the implementation of
               Sarbanes-Oxley and the preparation and filing of two tax returns
               for 2003. The filing of two tax returns was a result of our
               general partner's percentage interest in us being reduced below
               50% as a result of our offering of common units in May 2003,
               requiring a change in our tax year-end from September 30th to
               December 31st which necessitated the filing of an additional
               short year tax return. This expense is non-recurring.

         Our depreciation and amortization expense increased to $4.5 million in
the year ended December 31, 2004 as compared to $1.8 million in the year ended
December 31, 2003, an increase of $2.7 million (153%). This increase resulted
from depreciation associated with the acquisition of Spectrum ($2.4 million),
and our increased asset base associated with pipeline extensions and compressor
upgrades. We anticipate that our depreciation expense will increase in 2005 as a
result of a full year of depreciation associated with APLMC and depreciation
associated with our pipeline extensions and compressor upgrades.

         Our interest expense increased to $2.3 million in the year ended
December 31, 2004 as compared to $258,000 in the year ended December 31, 2003.
This increase of $2.0 million resulted from increased borrowings in the year
ended December 31, 2004 as compared to the year ended December 31, 2003. In July
2004, we borrowed $100.0 million to partially fund our acquisition of Spectrum.
Subsequently, in July 2004, we repaid $40.0 million of these borrowings upon the
completion of our public offering. In December 2004, we borrowed $10.0 million
on our revolver facility in order to repay $15.0 million of our term-loan
borrowings. Our interest expense in the year ended December 31, 2003 consisted
of fees on our outstanding borrowings, commitment fees on amounts not drawn on
our credit facility, and amortization of our debt issuance costs.

Year Ended December 31, 2003 Compared to Year Ended December 31, 2002

         Revenues. Our transportation and compression revenues increased to
$15.7 million in the year ended December 31, 2003 from $10.7 million in the year
ended December 31, 2002. This increase of $5.0 million (47%) resulted from an
increase in the average transportation rate paid to us ($4.4 million) and an
increase in the volumes of natural gas we transported ($629,000).

         Our transportation rate was $.82 per Mcf in the year ended December 31,
2003 as compared to $.58 per Mcf in the year ended December 31, 2002, an
increase of $.24 per Mcf (41%). During the year ended December 31, 2003, natural
gas prices increased significantly over the year ended December 31, 2002. Since
our transportation rates are generally at fixed percentages of the sale prices
of the natural gas we transport, the higher prices resulted in an increase in
our average transportation rate.

         Our average daily throughput volumes were 52,472 Mcfs in the year ended
December 31, 2003 as compared to 50,363 Mcfs in the year ended December 31,
2002, an increase of 2,109 Mcfs (4%). The increase in the average daily
throughput volume resulted principally from volumes associated with new wells
added to our pipeline system; we turned on-line 270 and 214 wells in the years
ended December 31, 2003 and 2002, respectively. These increases were partially
offset by the natural decline in production volumes from existing wells
connected to our gathering systems.

         Costs and Expenses. Our transportation and compression expenses
increased to $2.4 million in the year ended December 31, 2003 as compared to
$2.1 million in the year ended December 31, 2002, an increase of $358,900 (17%).
Our average cost per Mcf of transportation and compression increased to $.13 in
the year ended December 31, 2003 as compared to $.11 in the year ended December
31, 2002, an increase of $.02 (18%). This increase resulted primarily from an
increase in compressor expenses due to the addition of more compressors and
increased lease rates for our compressors. However, during 2003, we have
substantially completed the process of purchasing several compressors which we
previously leased. We anticipate this will reduce future compressor expenses on
a per Mcf basis.

         Our general and administrative expenses increased to $1.7 million in
the year ended December 31, 2003 as compared to $1.5 million in the year ended
December 31, 2002, an increase of $179,000 (12%). This increase primarily
resulted from an increase of $600,000 in allocations of compensation and
benefits from Atlas America and its affiliates due to an increase in management
time spent during the year on acquisitions, potential acquisitions and our
public offering. This increase was largely offset by a decrease in professional
fees which, in the prior period, had been higher than normal due to costs
associated with the proposed acquisition of Triton Coal Company. We were also
reimbursed $156,100 by Atlas America in the year ended December 31, 2003 for one
half of our unreimbursed costs associated with the proposed Triton acquisition.

         Our depreciation and amortization expense increased to $1.8 million in
the year ended December 31, 2003 as compared to $1.5 million in the year ended
December 31, 2002, an increase of $294,900 (20%). This increase resulted from
our increased asset base associated with pipeline extensions and compressor
upgrades and purchases.

LIQUIDITY AND CAPITAL RESOURCES

         Our primary cash requirements, in addition to normal operating
expenses, are for debt service, maintenance capital expenditures, expansion
capital expenditures and quarterly distributions to our unitholders and general
partner. In addition to cash generated from operations, we have the ability to
meet our cash requirements, other than distributions to our unitholders and
general partner, through borrowings under our credit facility. In general, we
expect to fund:

         o  cash distributions and maintenance capital expenditures through
            existing cash and cash flows from operating activities;

         o  expansion capital expenditures and working capital deficits through
            the retention of cash and additional borrowings;

                                      -29-
<PAGE>
         o  debt principal payments through additional borrowings as they become
            due or by the issuance of additional common units.

       At December 31, 2004, we had $54.5 outstanding and $77.8 million of
remaining borrowing capacity under our credit facilities.

         The following table summarizes our financial condition and liquidity at
the dates indicated:

         Net cash provided by operations of $25.6 million in the year ended
December 31, 2004 increased $11.9 million from $13.7 million in the year ended
December 31, 2003. The increase is derived principally from an increase in net
income before depreciation and amortization as a result of an increase in
volumes transported and prices received for our natural gas and NGLs. Net
income before depreciation and amortization was $22.8 million in the year ended
December 31, 2004, an increase of $11.4 million from the year ended December 31,
2003. This increase was principally due to the acquisition of Spectrum on July
16, 2004, resulting in five and one half months of operations included in the
current period. This increase was also due to the increase in the average
transportation rate we received in the year ended December 31, 2004 as compared
to the year ended December 31, 2003. During the year ended December 31, 2004,
our accounts payable-affiliates decreased as a result of the reimbursement of
advances from Atlas America in connection with expenses associated with the
terminated Alaska Pipeline acquisition.

         Net cash used in investing activities was $151.8 million for the year
ended December 31, 2004, an increase of $142.6 million from $9.2 million in the
year ended December 31, 2003. This increase was principally due to the
acquisition of Spectrum on July 16, 2004. In addition, capital expenditures
related to gathering system extensions and compressor upgrades to accommodate
new wells increased $2.4 million.

         Net cash provided by financing activities was $129.3 million for the
year ended December 31, 2004, an increase of $120.6 million from $8.7 million in
the year ended December 31, 2003. The primary reason for the increase was an
increase in proceeds received from our public offerings of $67.5 million and
increased net borrowings of $60.7 million on our revolving credit facility to
fund our acquisition of Spectrum. This increase was partially offset by an
increase of $6.3 million in distributions to partners in the current year period
as a result of an increase in net cash flow from operations and units
outstanding.

PARTNERSHIP DISTRIBUTIONS

         Our partnership agreement requires that we distribute 100% of available
cash to our partners within 45 days following the end of each calendar quarter
in accordance with their respective percentage interests. Available cash
consists generally of all of our cash receipts, less cash disbursements and net
additions to reserves, including any reserves required under debt instruments
for future principal and interest payments.

         Our general partner is granted discretion by our partnership agreement
to establish, maintain and adjust reserves for future operating expenses, debt
service, maintenance capital expenditures, rate refunds and distributions for
the next four quarters. These reserves are not restricted by magnitude, but only
by type of future cash requirements with which they can be associated. When our
general partner determines our quarterly distributions, it considers current and
expected reserve needs along with current and expected cash flows to identify
the appropriate sustainable distribution level.

                                      -30-
<PAGE>
         Available cash is initially distributed 98% to our limited partners and
2% to our general partner. These distribution percentages are modified to
provide for incentive distributions to be paid to our general partner if
quarterly distributions to unitholders exceed specified targets, as described in
Item 5 of this report.

         Incentive distributions are generally defined as all cash distributions
paid to our general partner that are in excess of 2% of the aggregate amount of
cash being distributed. The general partner's incentive distributions declared
for year ended December 31, 2004 was $2.8 million.

CAPITAL EXPENDITURES

         Our property and equipment was approximately 80% and 60% of our total
consolidated assets at December 31, 2004 and 2003, respectively. Capital
expenditures, other than the acquisition of Spectrum, were $10.0 million, $7.6
million and $5.2 million for the years ended December 31, 2004, 2003 and 2002,
respectively. These capital expenditures principally consisted of costs relating
to the expansion of our existing gathering systems to accommodate new wells
drilled in our service area and compressor upgrades. During 2004, we connected
335 wells to our Appalachian gathering system. As of December 31, 2004, we were
committed to expend approximately $8.6 million on pipeline extensions and
compressor station upgrades. We anticipate that our capital expenditures will
increase in 2005 as a result of an increase in the estimated number of well
connections to our gathering systems.

INFLATION AND CHANGES IN PRICES

         Inflation affects the operating expenses of our gathering systems.
Increases in those expenses are not necessarily offset by increases in
transportation fees that the gathering operations are able to charge. While we
anticipate that inflation will affect our future operating costs, we cannot
predict the timing or amounts of any such effects. In addition, the value of our
gathering systems has been and will continue to be affected by changes in
natural gas prices. Natural gas prices are subject to fluctuations which we are
unable to control or accurately predict.

ENVIRONMENTAL REGULATION

         Our operations are subject to federal, state and local laws and
regulations governing the release of regulated materials into the environment or
otherwise relating to environmental protection or human health or safety. We
believe that our operations and facilities are in substantial compliance with
applicable environmental laws and regulations. Any failure to comply with these
laws and regulations may result in the assessment of administrative, civil and
criminal penalties, imposition of remedial requirements, and issuance of
injunctions as to future compliance or other mandatory or consensual measures.
We have an ongoing environmental compliance program. However, risks of
accidental leaks or spills are associated with the transportation of natural
gas. There can be no assurance that we will not incur significant costs and
liabilities relating to claims for damages to property, the environment, natural
resources, or persons resulting from the operation of our business. Moreover, it
is possible that other developments, such as increasingly strict environmental
laws and regulations and enforcement policies hereunder, could result in
increased costs and liabilities to us.

         Environmental laws and regulations have changed substantially and
rapidly over the last 25 years, and we anticipate that there will be continuing
changes. One trend in environmental regulation is to increase reporting
obligations and place more restrictions and limitations on activities, such as
emissions of pollutants, generation and disposal of wastes and use, storage and
handling of chemical substances, that may impact human health, the environment
and/or endangered species. Increasingly strict environmental restrictions and
limitations have resulted in increased operating costs for us and other similar
businesses throughout the United States. It is possible that the costs of
compliance with environmental laws and regulations may continue to increase. We
will attempt to anticipate future regulatory requirements that might be imposed
and to plan accordingly, but there can be no assurance that we will identify and
properly anticipate each such charge, or that our efforts will prevent material
costs, if any, from arising.

CREDIT FACILITY

         Concurrently with the completion of the Spectrum acquisition, in July
2004, we entered into a $135.0 million senior secured term loan and revolving
credit facility administered by Wachovia Bank that replaced our $20.0 million
facility. The facility originally included a $35.0 million four year revolving
line of credit and a $100.0 million five year term loan. Upon the completion of
our July 2004 public offering, we repaid $40.0 million of the $100.0 million
term loan we had borrowed in order to complete the acquisition of Spectrum, and
in December 2004, we repaid an additional $15.0 million by borrowing $10.0
million on our revolving line of credit. In August 2004 and December 2004, the
revolving credit portion of the credit facility was increased to $75.0 million
and $90.0 million, respectively. Up to $5.0 million of the facility may be used
for standby letters of credit. Borrowings under the facility are secured by a
lien on and security interest in all of our property and that of our
subsidiaries and by the guaranty of each of our subsidiaries. The credit
facility bears interest at one of two rates, elected at our option:

         o  the base rate plus the applicable margin; or

         o  the adjusted LIBOR plus the applicable margin.

         The base rate for any day equals the higher of the federal funds rate
plus 1/2 of 1% or the Wachovia Bank prime rate. The applicable margin for the
revolving line of credit is as follows:

         o  where our leverage ratio, that is, the ratio of its debt to our
            earnings before interest, taxes, depreciation and amortization, or
            EBITDA, is less than or equal to 2.5, the applicable margin is 1.00%
            for base rate loans and 2.00% for LIBOR loans;

         o  where our leverage ratio is greater than 2.5 but less than or equal
            to 3.0, the applicable margin is 1.25% for base rate loans and 2.25%
            for LIBOR loans;

         o  where our leverage ratio is greater than 3.0 but less than or equal
            to 3.5, the applicable margin is 1.75% for base rate loans and 2.75%
            for LIBOR loans; and

         o  where our leverage ratio is greater than 3.5, the applicable margin
            is 2.25% for base rate loans and 3.25% for LIBOR loans.

         The applicable margin for the term loan is 0.75% higher for both base
rate loans and LIBOR loans.

         The credit facility requires us to maintain a ratio of funded debt to
EBITDA of not more than 4.0 to 1.0, reducing to 3.5 to 1.0 on June 30, 2005 and
an interest coverage ratio of not less than 3.0 to 1.0. In addition, we are
required to prepay the term loan with the net proceeds of any asset sales or
issuances of debt. With respect to any issuances of equity, it is required to
repay the term loan from the proceeds of such issuances to the extent its ratio
of funded debt to EBITDA exceeds 3.5 to 1.0. We are required to pay down
$560,000 in principal on the outstanding balance of the term loan quarterly. Any
prepayments of principal with proceeds from asset or equity sales that it makes
will be credited pro rata against this repayment obligation.

         The credit agreement contains covenants customary for loans of this
size, including restrictions on incurring additional debt and making material
acquisitions, and a prohibition on paying distributions to Atlas Pipeline's
unitholders if an event of default occurs. The events, which constitute an event
of default, are also customary for loans of this size, including payment
defaults, breaches of our representations or covenants contained in the credit
agreement, adverse judgments against it in excess of a specified amount, and a
change of control of our general partner.

                                      -32-
<PAGE>
         We had $10.0 million outstanding on our revolving credit facility at a
rate of 7.0% and $44.3 million outstanding on our term loan at a rate of 7.75%
at December 31, 2004. In addition, we had $2.2 million outstanding under letters

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

         The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires us to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of actual revenues and
expenses during the reporting period. Although we believe our estimates are
reasonable, actual results could differ from those estimates. Changes in these
estimates could materially affect our financial position, results of operations
or cash flows. Key estimates used by our management include estimates used to
record revenue and expense accruals, depreciation and amortization, asset
impairment and fair values of assets acquired. We summarize our significant
accounting policies in Note 2 to our Consolidated Financial Statements included
in this report. We discuss below the critical accounting policies that we have
identified.

                                      -33-

Revenue Recognition

         We recognize revenues in the Appalachian Basin area at the time the
natural gas is transported through the gathering systems. Under the terms of our
natural gas gathering agreements with Atlas America and its affiliates, we
receive fees for gathering natural gas from wells owned by Atlas America, by
drilling investment partnerships sponsored by Atlas America or by independent
third parties. The fees received for the gathering services are generally the
greater of 16% of the gross sales price for gas produced from the wells, or $.35
or $.40 per mcf, depending on the ownership of the well. Substantially all gas
gathering revenues are derived under this agreement. Fees for transportation
services provided to independent third parties whose wells are connected to our
gathering systems are at separately negotiated prices.

         We recognize revenues in the Mid-Continent area at the time the natural
gas is purchased, processed and the resulting residue gas and NGLs are sold. The
majority of these revenues are based on POP contracts, the remainder are
fixed-fee contracts. Under our POP purchasing arrangements, we purchase natural
gas at the wellhead, process the natural gas by extracting NGLs and removing
impurities and sell the residue gas and NGLs at market-based prices, remitting
to producers a contractually-determined percentage of the sale proceeds.

         We routinely make accruals for both revenues and expenses due to the
timing of receiving information from third parties and reconciling our records
with those of third parties. We have determined these estimates using available
market data and valuation methodologies. We believe our estimates for these
items are reasonable, but cannot assure you that actual amounts will not vary
from estimated amounts.

Depreciation and Amortization

         We calculate our depreciation based on the estimated useful lives and
salvage values of our assets. However, factors such as usage, equipment failure,
competition, regulation or environmental matters could cause us to change our
estimates, thus impacting the future calculation of depreciation and
amortization.

Impairment of Assets

         In accordance with Statement of Financial Accounting Standards, or
SFAS, 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," we
review long-lived assets for impairment whenever events or changes in
circumstances indicate that the carrying amount of long-lived assets may not be
recoverable. We determine if our long-lived assets are impaired by comparing the
carrying amount of an asset or group of assets with the estimated undiscounted
future cash flows associated with such asset or group of assets. If the carrying
amount is greater than the estimated undiscounted future cash flows, an
impairment loss is recognized to reduce the carrying value to fair value.

         Our operations are subject to numerous factors which could affect
future cash flows which we discuss in Item 1, "Business-Risk Factors". We
continuously monitor these factors and pursue alternative strategies to maintain
or enhance cash flows associated with these assets; however, we cannot assure
you that we can mitigate the effects, if any, on future cash flows related to
any changes in these factors.

Goodwill

         At December 31, 2004, we had $2.3 million of goodwill, all of which
relates to our acquisition of pipeline assets. We test our goodwill for
impairment at each year end by comparing fair values to our carrying values. The
evaluation of impairment under SFAS 142, "Goodwill and Other Intangible Assets,"
requires the use of projections, estimates and assumptions as to the future
performance of the operations, including anticipated future revenues, expected
future operating costs and the discount factor used. Actual results could differ
from projections resulting in revisions to our assumptions and, if required,
recognizing an impairment loss. Our test during the current year resulted in no
impairment. We will continue to evaluate our goodwill at least annually and will
reflect the impairment of goodwill, if any, in operating income in the income
statement in the period in which the impairment is indicated.

                                      -34-

Fair Value of Derivative Commodity Contracts

         We utilize various exchange-traded and over-the-counter commodity
financial instrument contracts to limit our exposure to fluctuations in natural
gas and NGL prices, primarily commodity forwards, futures, swaps, options and
certain basis contracts. Many of these contracts, which, in accordance with SFAS
No. 133 "Accounting for Derivative Instruments and Hedging Activities", are not
accounted for as hedges, are marked to fair value on the income statement. We
utilize published settlement prices for exchange-traded contracts, and for our
other contracts, use quotes provided by brokers, and estimates of market prices
based on daily contract activity to estimate the fair value of these contracts.
The values have been adjusted to reflect the potential impact of liquidating a
position in an orderly manner over a reasonable period of time under existing
market conditions. Changes in the methods used to determine the fair value of
these contracts could have a material effect on our results of operations. We do
not anticipate future changes in the methods used to determine the fair value of
these derivative contracts. . On our contracts that are designated as cash flow
hedging instruments in accordance with SFAS No. 133, the effective portion of
the hedged gain or loss is initially reported as a component of other
comprehensive income and is subsequently reclassified into earnings when the
instrument settles. The ineffective portion of the gain or loss is reported in
earnings immediately.

Volume Measurement

         We record amounts for natural gas gathering and transportation revenue,
NGL transportation and processing revenue, natural gas sales and natural gas
purchases, and the sale of production based on volumetric calculations.
Variances resulting from such calculations are inherent in our business.

RECENTLY ISSUED FINANCIAL ACCOUNTING STANDARDS

         In December 2004, the Financial Accounting Standards Board ("FASB")
issued Statement No. 123 (R) (revised 2004) Share-Based Payment, which is a
revision of Statement of Financial Accounting Standards ("SFAS") No. 123,
Accounting for Stock-Based Compensation. Statement 123 (R) supersedes Accounting
Principal Board Opinion (APB) No. 25, Accounting for Stock Issued to Employees,
and amends Statement of Financial Accounting Standards (SFAS) No. 95, Statement
of Cash Flows. Generally, the approach to accounting in Statement 123 (R)
requires all share-based payments to employees, including grants of employee
stock options, to be recognized in the financial statements based on their fair
values. Currently the Company accounts for these payments under the intrinsic
value provisions of APB No. 25 with no expense recognition in the financial
statements. Statement 123 (R) is effective for the Partnership beginning July 1,
2005. The Statement offers several alternatives for implementation. At this
time, management has not made a decision as to the alternative it may select.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         The primary objective of the following information is to provide
forward-looking quantitative and qualitative information about our potential
exposure to market risks. The term "market risk" refers to the risk of loss
arising from adverse changes in interest rates and oil and gas prices. The
disclosures are not meant to be precise indicators of expected future losses,
but rather indicators of reasonable possible losses. This forward-looking
information provides indicators of how we view and manage our ongoing market
risk exposures. All of our market risk sensitive instruments were entered into
for purposes other than trading.

GENERAL

         All of our assets and liabilities are denominated in U.S. dollars, and
as a result, we do not have exposure to currency exchange risks.

         We are exposed to various market risks, principally fluctuating
interest rates and changes in commodity prices. These risks can impact our
results of operations, cash flows and financial position. We manage these risks
through regular operating and financing activities and periodically use
derivative financial instruments.

         The following analysis presents the effect on our earnings, cash flows
and financial position as if the hypothetical changes in market risk factors
occurred on December 31, 2004. Only the potential impacts of hypothetical
assumptions are analyzed. The analysis does not consider other possible effects
that could impact our business.

         Interest Rate Risk At December 31, 2004, we had a $90.0 million
revolving credit facility ($10.0 million outstanding) and a $45.0 million term
loan ($44.3 million outstanding) to fund the expansion of our existing gathering
systems and the acquisitions of other natural gas gathering systems. The
weighted average interest rate for these borrowings was 7.6% at December 31,
2004.

         Holding all other variables constant, if interest rates hypothetically
increased or decreased by 10%, our net annual income would change by
approximately $413,000.

         Commodity Price Risk. We are exposed to commodity prices as a result of
being paid for certain services in the form of commodities rather than cash. For
gathering services, we receive fees or commodities from the producers to bring
the raw natural gas from the wellhead to the processing plant. For processing
services, we either receive fees or commodities as payment for these services,
based on the type of contractual agreement. Based on our current contract mix,
we have a long NGL position and a long gas position. Based upon our portfolio of
supply contracts, a 10% change in the average price of NGLs, the average price
of natural gas and the average price of crude oil sold and processed by APLMC
would result in a change to our annual income of approximately $1.0 million.

         Through our subsidiary, APLMC, we acquired and/or entered into certain
financial swap and option instruments that are classified as cash flow hedges in
accordance with SFAS No. 133. APLMC entered into these instruments to hedge the
forecasted natural gas, natural gas liquids and condensate sales against the
variability in expected future cash flows attributable to changes in market
prices. The swap instruments are contractual agreements between counterparties
to exchange obligations of money as the underlying natural gas, natural gas
liquids and condensate is sold. Under these swap agreements, APLMC receives a
fixed price and pays a floating price based on certain indices for the relevant
contract period. The options fix the price for APLMC within the puts purchased
and calls sold.

         Derivatives are recorded on the balance sheet as assets or liabilities
at fair value. For derivatives qualifying as hedges, the effective portion of
changes in fair value are recognized in stockholders' equity as Other
Comprehensive Income and reclassified to earnings as such transactions are
settled. For non-qualifying derivatives and for the ineffective portion of
qualifying derivatives, changes in fair value are recognized in earnings as they
occur. At December 31, 2004, we reflected a hedging liability on our Balance
Sheet of $2.6 million. Of the $2.6 million liability at December 31, 2004, $1.9
million of losses will be reclassified to earnings over the next twelve month
period as these contracts expire and $708,000 in later periods, if the fair
values of the instruments remain constant. Actual amounts that will be
reclassified will vary as a result of future changes in prices. We
recognized a loss of $2,000 related to these hedging instruments in the year
ended December 31, 2004. Ineffective gains or losses are recorded in income
while the hedge contract is open and may increase or decrease until settlement
of the contract. A loss of $257,000 resulting from ineffective hedges is
included in income for the year ended December 31, 2004. These losses are
included in natural gas and liquids revenues on the Partnership's Consolidated
Statements of Income.

                                      -36-

         A portion of our future natural gas sales is periodically hedged
through the use of swaps and collar contracts. We reflect realized gains and
losses on these instruments in the contract month being hedged as an adjustment
to gas revenue.

         As of December 31, 2004, Atlas Pipeline had the following natural gas
liquids, natural gas, and crude oil volumes hedged.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA


             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


Partners
Atlas Pipeline Partners, L.P.

We have audited the accompanying consolidated balance sheets of Atlas Pipeline
Partners, L.P. and subsidiaries as of December 31, 2004 and 2003, and the
related consolidated statements of income, comprehensive income, partners'
capital (deficit), and cash flows for each of the three years in the period
ended December 31, 2004. These financial statements are the responsibility of
the Partnership's management. Our responsibility is to express an opinion on
these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audits to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Atlas
Pipeline Partners, L.P. and subsidiaries as of December 31, 2004 and 2003 and
the consolidated results of its operations and cash flows for each of the three
years in the period ended December 31, 2004, in conformity with accounting
principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company
Accounting Oversight Board (United States), the effectiveness of Atlas Pipeline
Partners, L.P.'s internal control over financial reporting as of December 31,
2004, based on criteria established in Internal Control-Integrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission
(COSO) and our report dated March 9, 2005 expressed an unqualified opinion.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - NATURE OF OPERATIONS

THE PARTNERSHIP

         Atlas Pipeline Partners, L.P. (the "Partnership") is a Delaware limited
partnership formed in May 1999 to acquire, own and operate natural gas gathering
systems theretofore owned by Atlas America, Inc. ("Atlas" or "Atlas America")
and its affiliates, Viking Resources Corporation ("VRC") and Resource Energy,
Inc. ("REI") (collectively referred to as the "Predecessor"). Atlas America is
an 80% owned subsidiary of Resource America, Inc. ("RAI" or "Parent"). In May
2004, Atlas completed its initial public offering of 2,645,000 shares of its
common stock, which trades under the symbol ATLS on the NASDAQ system. RAI is a
publicly traded company (NASDAQ:REXI) operating in the structured finance,
equipment leasing, real estate and energy sectors.

PARTNERSHIP STRUCTURE AND MANAGEMENT

         The Partnership's operations are conducted through subsidiary entities
whose equity interests are owned by the Partnership's operating subsidiary,
Atlas Pipeline Operating Partnership, L.P., (the "Operating Partnership"). Atlas
Pipeline Partners GP, LLC (a wholly-owned subsidiary of Atlas (the "General
Partner")), owns, through its general partner interests in the Partnership and
the Operating Partnership, a 2% general partner interest in the consolidated
pipeline operations. The remaining 98% consists of limited partner interests of
which 77% consists of common units ("Common Units") and 23% consists of
subordinated units ("Subordinated Units"). The Subordinated Units are
subordinated to the rights of the holders of Common Units. On January 1, 2005,
the subordination period ended and the subordinated units converted into Common
Units on a one-for-one basis. Through its general partner interest, the General
Partner effectively manages and controls both the Partnership and the Operating
Partnership.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         A summary of the significant accounting policies consistently applied
in the preparation of the accompanying consolidated financial statements
follows.

PRINCIPLES OF CONSOLIDATION

         The consolidated financial statements include the accounts of the
Partnership, the Operating Partnership and the Operating Partnership's
wholly-owned subsidiaries. The General Partner's interest in the Operating
Partnership is reported as part of its overall 2% general partner interest in
the Partnership, as opposed to a minority interest. All material intercompany
transactions have been eliminated.

ACCOUNTING ESTIMATES

         Certain amounts included in or affecting the Partnership's consolidated
financial statements and related disclosures must be estimated, requiring the
Partnership to make certain assumptions with respect to values or conditions
that cannot be known with certainty at the time the financial statements are
prepared.

         The preparation of its consolidated financial statements in conformity
with accounting principles generally accepted in the United States of America
requires the Partnership to make estimates and assumptions that affect:

                                      -44-

                 ATLAS PIPELINE PARTNERS, L.P. AND SUBSIDIARIES
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

ACCOUNTING ESTIMATES - (CONTINUED)

         o  the amount the Partnership reports for assets and liabilities;

         o  the Partnership's disclosure of contingent assets and liabilities at
            the date of the financial statements; and

         o  the amounts the Partnership reports for revenues and expenses during
            the reporting period.

         Therefore, the reported amounts of the Partnership's assets and
liabilities, revenues and expenses and associated disclosures with respect to
contingent assets and obligations are necessarily affected by these estimates.
The Partnership evaluates these estimates on an ongoing basis, utilizing
historical experience, consultation with experts and other methods the
Partnership considers reasonable in the particular circumstances. Nevertheless,
actual results may differ significantly from the Partnership's estimates. Any
effects on the Partnership's business, financial position or results of
operations resulting from revisions to these estimates are recorded in the
period in which the facts that give rise to the revision become known.

RECLASSIFICATIONS

         Certain reclassifications have been made to the 2003 and fiscal 2002
consolidated financial statements to conform to the 2004 presentation.

PROPERTY AND EQUIPMENT

         Depreciation is provided for in amounts sufficient to relate the cost
of depreciable assets to operations over the estimated useful lives of the
assets. Gas gathering, transmission and processing facilities are depreciated
over 15 to 40 years using the straight-line method. Other equipment is
depreciated over 5 to 10 years using the straight-line method.

IMPAIRMENT OF LONG-LIVED ASSETS

         The Partnership reviews its long-lived assets for impairment whenever
events or circumstances indicate that the carrying amount of an asset may not be
recoverable. If it is determined that an asset's estimated future cash flows
will not be sufficient to recover its carrying amount, an impairment charge will
be recorded to reduce the carrying amount for that asset to its estimated fair
value if such carrying amount exceeds the fair value.

DISTRIBUTIONS

         The Partnership is required to distribute, within 45 days of the end of
each quarter, all of its available cash (as defined in the partnership
agreement) for that quarter. For each quarter during the subordination period
(through December 31, 2004), to the extent there is sufficient cash available,
the Common Unit holders have the right to receive a minimum quarterly
distribution ("MQD") of $.42 per unit prior to any distribution to the
subordinated units. If distributions in any quarter exceed specified target
levels, the General Partner will receive between 15% and 50% of such
distributions in excess of the specified target levels.

ENVIRONMENTAL MATTERS

         The Partnership is subject to various federal, state and local laws and
regulations relating to the protection of the environment. The Partnership has
established procedures for the ongoing evaluation of its operations, to identify
potential environmental exposures and to comply with regulatory policies and
procedures.

         The Partnership accounts for environmental contingencies in accordance
with SFAS 5, "Accounting for Contingencies." Environmental expenditures that
relate to current operations are expensed or capitalized as appropriate.
Expenditures that relate to an existing condition caused by past operations, and
do not contribute to current or future revenue generation, are expensed.
Liabilities are recorded when environmental assessments and/or clean-ups are
probable, and the costs can be reasonably estimated. The Partnership maintains
insurance which may cover in whole or in part certain environmental
expenditures. For the three years ended December 31, 2004, the Partnership had
no environmental matters requiring specific disclosure or requiring recording of
a liability.

SEGMENT INFORMATION

         The Partnership has two business segments: natural gas gathering and
transmission located in the Appalachian Basin area ("Appalachia") and gathering,
transmission and processing located in the Mid-Continent area ("Mid-Continent").
Appalachian revenues are, for the most part, based on contractual arrangements
with Atlas and its affiliates. Mid-Continent revenues are, for the most part,
derived from the sale of residue gas and NGLs to purchasers at the tailgate of
the processing plant.

REVENUE RECOGNITION

         Revenues in the Appalachian Basin area are recognized at the time the
natural gas is transported through the gathering systems. Under the terms of its
natural gas gathering agreements with Atlas and its affiliates, the Partnership
receives fees for gathering natural gas from wells owned by Atlas, by drilling
investment partnerships sponsored by Atlas or by independent third parties. The
fees received for the gathering services are generally the greater of 16% of the
gross sales price for gas produced from the wells, or $.35 or $.40 per thousand
cubic feet ("mcf"), depending on the ownership of the well. Substantially all
gas gathering revenues are derived under this agreement. Fees for transportation
services provided to independent third parties whose wells are connected to the
Partnership's gathering systems are at separately negotiated prices.

         Revenues in the Mid-Continent area are recognized at the time the
natural gas is processed and the resulting residue gas and natural gas liquids
("NGLs") are sold. The majority of these revenues are based on percentage of
proceeds, or POP contracts; the remainder are fixed-fee contracts. Under its POP
purchasing arrangements, the Partnership purchases natural gas at the wellhead,
processes the natural gas by extracting NGLs and removing impurities and sells
the residue gas and NGLs at market-based prices, remitting to producers a
contractually-determined percentage of the sale proceeds.

FAIR VALUE OF FINANCIAL INSTRUMENTS

         For cash and cash equivalents, receivables and payables, the carrying
amounts approximate fair values because of the short maturity of these
instruments. The carrying value of long-term debt approximates fair market value
since interest rates approximate current market rates.

DERIVATIVE INSTRUMENTS

         The Partnership applies the provisions of SFAS No. 133, "Accounting for
Derivative Instruments and Hedging Activities" ("SFAS 133"). SFAS 133 requires
each derivative instrument to be recorded in the balance sheet as either an
asset or liability measured at fair value. Changes in a derivative instrument's
fair value are recognized currently in earnings unless specific hedge accounting
criteria are met.

CASH FLOW STATEMENTS

         For purposes of the statements of cash flows, all highly liquid debt
instruments purchased with a maturity of three months or less are considered to
be cash equivalents. Supplemental disclosure of cash flow information (in

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

CONCENTRATION OF CREDIT RISK

         Financial instruments, which potentially subject the Partnership to
concentrations of credit risk, consist principally of periodic temporary
investments of cash. The Partnership places its temporary cash investments in
high quality short-term money market instruments and deposits with high quality
financial institutions. At December 31, 2004, the Partnership and its
subsidiaries had $21.9 million in deposits at one bank, of which $21.6 million
was over the insurance limit of the Federal Deposit Insurance Corporation. No
losses have been experienced on such investments. Also see Note 16 with regards
to major customers.

GOODWILL

At December 31, 2004, the Partnership had $2.3 million of goodwill, all of which
relates to its acquisition of pipeline assets. The Partnership tests its
goodwill for impairment at each year end by comparing fair values to its
carrying values. The evaluation of impairment under SFAS 142, "Goodwill and
Other Intangible Assets," requires the use of projections, estimates and
assumptions as to the future performance of the operations, including
anticipated future revenues, expected future operating costs and the discount
factor used. Actual results could differ from projections resulting in revisions
to the Partnership's assumptions and, if required, recognizing an impairment
loss. The Partnership's test during the current year resulted in no impairment.
The Partnership will continue to evaluate its goodwill at least annually and
will reflect the impairment of goodwill, if any, in operating income in the
income statement in the period in which the impairment is indicated.

COMPREHENSIVE INCOME (LOSS)

         Comprehensive (loss) income includes net income (loss) and all other
changes in the equity of a business during a period from transactions and other
events and circumstances from non-owner sources. These changes, other than net
income (loss), are referred to as "other comprehensive income (loss)" and for
the Partnership include changes in the fair value of derivative contracts
accounted for as hedges. The components of accumulated other comprehensive
(loss) income are as follows:

FEDERAL INCOME TAXES

         The Partnership is a limited partnership. As a result, the
Partnership's income for federal income tax purposes is reportable on the tax
returns of the individual partners. Accordingly, no recognition has been given
to income taxes in the accompanying financial statements of the Partnership.

         Net income, for financial statement purposes, may differ significantly
from taxable income reportable to unitholders as a result of differences between
the tax bases and financial reporting bases of assets and liabilities and the
taxable income allocation requirements under the partnership agreement. These
different allocations can and usually will result in significantly different tax
capital account balances in comparison to the capital accounts per the
consolidated financial statements.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

STOCK BASED COMPENSATION

         The Partnership issues phantom units to its directors and employees of
Atlas America and its affiliates under its Long-Term Incentive Plan ("the Plan")
(see Notes 8 and 15). The Partnership accounts for the issuances under this Plan
under the Accounting Principles Board Opinion No. 25, "Accounting for Stock
Issued to Employees" and its related interpretations.

RECENTLY ISSUED FINANCIAL ACCOUNTING STANDARD

         In December 2004, the Financial Accounting Standards Board ("FASB")
issued Statement No. 123 (R) (revised 2004) Share-Based Payment, which is a
revision of Statement of Financial Accounting Standards ("SFAS") No. 123,
Accounting for Stock-Based Compensation. Statement 123 (R) supersedes Accounting
Principal Board Opinion (APB) No. 25, Accounting for Stock Issued to Employees,
and amends Statement of Financial Accounting Standards (SFAS) No. 95, Statement
of Cash Flows. Generally, the approach to accounting in Statement 123 (R)
requires all share-based payments to employees, including grants of employee
stock options, to be recognized in the financial statements based on their fair
values. Currently the Company accounts for these payments under the intrinsic
value provisions of APB No. 25 with no expense recognition in the financial
statements. Statement 123 (R) is effective for the Partnership beginning July 1,
2005. The Statement offers several alternatives for implementation. At this
time, management has not made a decision as to the alternative it may select.

NOTE 3 - NET INCOME PER UNIT

         Net income per limited partner unit is based on the weighted average
number of common and subordinated units outstanding during the period. Basic net
income per limited partner unit is computed by dividing net income, after
deducting the general partner's 2% and incentive distributions, by the weighted
average number of outstanding common units and subordinated units. Diluted net
income per limited partner unit is computed by dividing net income attributable
to limited partners by the sum of the weighted average number of common and
subordinated units outstanding and the weighted average number of phantom units
during the period. Phantom units consist of common units issuable under the
terms of the Partnership's Long-Term Incentive Plan.

         Phantom units issued in 2004 totaling 58,752 units were not included in
the computation of diluted net income per limited partner unit for the year
ended December 31, 2004 as their effect would have been anti-dilutive.

NOTE 6 -SPECTRUM ACQUISITION

         On July 16, 2004, the Partnership acquired Spectrum Field Services,
Inc. ("Spectrum or Mid-Continent"), for approximately $142.4 million, including
transaction costs and the payment of taxes due as a result of the transaction.
Spectrum's principal assets include 1,900 miles of natural gas pipelines and a
natural gas processing facility in Velma, Oklahoma. Spectrum has changed its
name to Atlas Pipeline Mid-Continent, LLC ("APLMC"). This acquisition
significantly increased the Partnership's size and diversifies the natural gas
supply basins in which it operates and the natural gas midstream services it
provides to its customers.

         In connection with the acquisition of Spectrum, the Partnership entered
into commitment agreements with Resource America and Atlas America for the
purchase of up to $25.0 million of preferred units in the Operating Partnership.
In consideration for their commitments, upon the closing of the Spectrum
acquisition and the purchase by each of $10.0 million of preferred units, the
Partnership paid Resource America and Atlas America commitment fees of $750,000
and $500,000, respectively.

         In April and July 2004, the Partnership completed public offerings of
750,000 and 2,100,000 common units, respectively. The net proceeds after
underwriting discounts, commissions and costs were $25.2 million and $67.5
million, respectively. The General Partner simultaneously contributed $535,000
and $1.5 million to the Partnership in order to maintain its 2% general partner
interest in the Partnership.

NOTE 6 - SPECTRUM ACQUISITION  - (CONTINUED)

         The Partnership financed the Spectrum acquisition, including
approximately $4.3 million of transaction costs, as follows:

         o  borrowing $100.0 million under the term loan portion of its $135.0
            million senior secured term loan and revolving credit facility
            administered by Wachovia Bank, National Association (Note 11);

         o  using the $20.0 million of proceeds received from the sale to
            Resource America and Atlas America of preferred units in the
            Operating Partnership; and

         o  using $22.4 million of net proceeds from the Partnership's April
            2004 common unit offering.

         On July 20, 2004, the Partnership used a portion of the July 2004
public offering to repay $40.0 million of the borrowings under its $135.0
million credit facility and to repurchase the preferred units from Resource
America and Atlas America for $20.4 million.

         On March 9, 2004, the Oklahoma Tax Commission ("OTC") filed a petition
against Spectrum alleging that Spectrum underpaid gross production taxes
beginning in June 2000. The OTC is seeking a settlement of $5.0 million plus
interest and penalties. The Partnership plans on defending itself vigorously. In
addition, under the terms of the Spectrum purchase agreement, $14.0 million has
been placed in escrow to cover the costs of any adverse settlement resulting
from the petition and other indemnification obligations of the purchase
agreement.

         The acquisition was accounted for using the purchase method of
accounting under SFAS No. 141 "Business Combinations." The following table
presents the allocation of the acquisition cost, including professional fees and
other related acquisition costs to the assets acquired and liabilities assumed,

NOTE 7 - DERIVATIVE INSTRUMENTS

         The Partnership, through its subsidiary, APLMC, acquired and/or entered
into certain financial swap and option instruments that are classified as cash
flow hedges in accordance with SFAS No. 133. APLMC entered into these
instruments to hedge the forecasted natural gas, natural gas liquids and
condensate sales against the variability in expected future cash flows
attributable to changes in market prices. The swap instruments are contractual
agreements between counterparties to exchange obligations of money as the
underlying natural gas, natural gas liquids and condensate is sold. Under these
swap agreements, APLMC receives a fixed price and pays a floating price based on
certain indices for the relevant contract period. The options fix the price for
APLMC within the puts purchased and calls sold.

NOTE 7 -DERIVATIVE INSTRUMENTS - (CONTINUED)

         The Partnership formally documents all relationships between hedging
instruments and the items being hedged, including the Partnership's risk
management objective and strategy for undertaking the hedging transactions. This
includes matching the natural gas futures and options contracts to the
forecasted transactions. The Partnership assesses, both at the inception of the
hedge and on an ongoing basis, whether the derivatives are highly effective in
offsetting changes in the fair value of hedged items. If it is determined that a
derivative is not highly effective as a hedge or it has ceased to be a highly
effective hedge, due to the loss of correlation between changes in gas reference
prices under a hedging instrument and actual gas prices, the Partnership will
discontinue hedge accounting for the derivative and subsequent changes in fair
value for the derivative will be recognized immediately into earnings.

         Derivatives are recorded on the balance sheet as assets or liabilities
at fair value. For derivatives qualifying as hedges, the effective portion of
changes in fair value are recognized in stockholders' equity as Other
Comprehensive Income and reclassified to earnings as such transactions are
settled. For non-qualifying derivatives and for the ineffective portion of
qualifying derivatives, changes in fair value are recognized in earnings as they
occur. At December 31, 2004, APLMC reflected a net hedging liability on its
Balance Sheet of $2.6 million. Of the $2.6 million net liability at December 31,
2004, $1.9 million ($40,000 is included in accounts receivable, less $2.0
million shown as accrued hedge liability on the consolidated balance sheet) of
losses will be reclassified to earnings over the next twelve month period as
these contracts expire and $708,000 ($14,000 is included in other assets, less
$722,000 shown as other long-term liabilities on the consolidated balance sheet)
will be reclassified in later periods, if the fair values of the instruments
remain constant. Actual amounts that will be reclassified will vary as a result
of future changes in prices. The Company recognized a loss of $2,000 related to
these hedging instruments in the year ended December 31, 2004. Ineffective gains
or losses are recorded in income while the hedge contract is open and may
increase or decrease until settlement of the contract. A loss of $257,000
resulting from ineffective hedges is included in income for the year ended
December 31, 2004. These losses are included in natural gas and liquids revenues
on the Partnership's Consolidated Statements of Income.

         A portion of the Company's future natural gas sales is periodically
hedged through the use of swaps and collar contracts. Realized gains and losses
on these instruments are reflected in the contract month being hedged as an
adjustment to gas revenue.

         As of December 31, 2004, The Partnership had the following natural gas
liquids, natural gas, and crude oil volumes hedged.

NOTE 8 - SPECIAL MEETING OF UNITHOLDERS

         On February 11, 2004, at a special meeting of unitholders, the
following were approved:

         o  The issuance of up to 2.0 million common units in connection with
            the Partnership's proposed acquisition of Alaska Pipeline Company,
            of which 750,000 common units were issued in April 2004 (see
            Note 6).

         o  The Atlas Pipeline Partners, L.P. Long-Term Incentive Plan in which
            officers, employees and non-employee managing board members of the
            General Partner and employees of the General Partner's affiliates,
            consultants and joint venture partners who perform services for the
            Partnership are eligible to participate. The Plan is administered by
            a committee appointed by the General Partner's managing board (the
            "Committee"), which sets the terms of awards under the Plan. The
            Committee may make awards of either phantom units or options for an
            aggregate of 435,000 common units, provided that the maximum number
            of phantom units that may be awarded in total to non-employee
            managing board members is 10,000. A phantom unit entitles the
            grantee to receive a common unit upon the vesting of the phantom
            unit or, at the discretion of the Committee, cash equivalent to the
            fair market value of a common unit. In addition, the Committee may
            grant a participant the right, known as a DER, to receive cash per
            phantom unit in an amount equal to, and at the same time as, the
            cash distributions the Partnership makes on a common unit during the
            period the phantom unit is outstanding. An option entitles the
            grantee to purchase the Partnership's common units at an exercise
            price determined by the Committee, which may be less than, equal to
            or more than the fair market value of the Partnership's common units
            on the date of the grant. The Committee also has

NOTE 8 - SPECIAL MEETING OF UNITHOLDERS - (CONTINUED)

            discretion to determine how the exercise price may be paid. Except
            for phantom units awarded to non-employee managing board members
            of the General Partner, the managing board will determine the
            vesting period for phantom units and the exercise period for
            options. Phantom units awarded to non-employee managing board
            members will vest over a 4-year period at the rate of 25% per
            year. Both types of awards will automatically vest upon a change
            of control, as defined in the Plan (see Note 15).

         After the special meeting of unitholders was adjourned and was
reconvened on March 9, 2004, the unitholders approved amendments to the
Partnership Agreement that removed the limitations on the Partnership's ability
to issue common units and incur debt.

NOTE 9 - RELATED PARTY TRANSACTIONS

         The Partnership is affiliated with RAI and its subsidiaries, including
Atlas, VRC and REI ("Affiliates"). The Partnership is dependent upon the
resources and services provided by RAI and these Affiliates. Accounts
receivable/payable-affiliates represents the net balance due from/to these
Affiliates for natural gas transported through the gathering systems, net of
reimbursements for Partnership costs and expenses paid by these Affiliates.
Substantially all Partnership revenue in Appalachia is from these Affiliates.

         The Partnership does not directly employ any persons to manage or
operate its business. These functions are provided by the General Partner and
employees of RAI and/or its Affiliates. The General Partner does not receive a
management fee or other compensation in connection with its management of the
Partnership apart from its interest as general partner and its right to receive
incentive distributions. The Partnership reimburses Atlas and/or its Affiliates
for all direct and indirect costs of services provided, including the cost of
employees, officer and managing board member compensation and benefits properly
allocable to the Partnership and all other expenses necessary or appropriate to
the conduct of the business of, and allocable to, the Partnership.

         The partnership agreement provides that the General Partner will
determine the costs and expenses that are allocable to the Partnership in any
reasonable manner determined by the General Partner at its sole discretion. For
the years ended December 31, 2004, 2003 and 2002, such reimbursements were
approximately $15.9 million, $11.7 million and $8.8 million, respectively,
including certain costs that have been capitalized by the Partnership.

         Under an agreement with Atlas, VRC and REI, Atlas must construct up to
2,500 feet of sales lines from its existing wells to a point of connection to
the Partnership's gathering systems. The Partnership must, at its own cost,
extend its system to connect to any such lines extended to within 1,000 feet of
its gathering systems. With respect to wells to be drilled by Atlas that will be
more than 3,500 feet from the Partnership's gathering systems, the Partnership
has various options to connect those wells to its gathering systems at its own
cost.

         Atlas had agreed to provide the Partnership with financing for the cost
of constructing new gathering system expansions through February 2, 2005, on a
stand-by basis. The commitment was for a maximum of $1.5 million in any contract
year. This commitment expired without being used.

NOTE 9 - RELATED PARTY TRANSACTIONS - (CONTINUED)

         In connection with the proposed acquisition of Alaska Pipeline Company,
L.L.C. ("Alaska Pipeline") (see Note 14), the Partnership paid RAI a fee of
$70,750 in the year ended December 31, 2004.

NOTE 10 - DISTRIBUTION DECLARED

         The Partnership makes quarterly cash distributions of its available
cash, generally defined as cash on hand at the end of the quarter less cash
reserves deemed appropriate to provide for future operating costs, potential
acquisitions and future distributions.

         On December 17, 2004, the Partnership declared a cash distribution of
$0.72 per unit on its outstanding common units and subordinated units. The
distribution represents the available cash flow less cash reserves for the three
months ended December 31, 2004. The $6.5 million distribution, which includes a
distribution of $1.3 million to the general partner, will be paid on February
11, 2005 to unitholders of record on December 31, 2004.

         Available cash is initially distributed 98% to limited partners and 2%
to the general partner. These distribution percentages are modified to provide
for incentive distributions to be paid to the general partner in the event that
quarterly distributions to unitholders exceed certain specified targets.
Incentive distributions are generally defined as all cash distributions paid to
the general partner that are in excess of 2% of the aggregate amount of cash
being distributed. The general partner's incentive distributions for the
distributions declared for the year ended December 31, 2004, 2003 and 2002 were
$2.8 million, $809,000 and $272,000, respectively.

         Concurrently with the completion of the Spectrum acquisition, in July
2004, the Partnership entered into a $135.0 million senior secured term loan and
revolving credit facility administered by Wachovia Bank that replaced its $20.0
million facility. The facility originally included a $35.0 million four year
revolving line of credit and a $100.0 million five year term loan.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

NOTE 11 -CREDIT FACILITIES - (CONTINUED)

Upon the completion of its July 2004 public offering, the Partnership repaid
$40.0 million of the $100.0 million term loan it had borrowed in order to
complete the acquisition of Spectrum, and in December 2004, the Partnership
repaid an additional $15.0 million by borrowing $10.0 million on its revolving
line of credit. In August 2004 and December 2004, the revolving credit portion
of the facility was increased to $75.0 million and $90.0 million, respectively.
Up to $5.0 million of the facility may be used for standby letters of credit.
Borrowings under the facility are secured by a lien on and security interest in
all of Atlas Pipeline's property and that of its subsidiaries and by the
guaranty of each of its subsidiaries. The credit facility bears interest at one
of two rates, elected at the Partnership's option:

         o  the base rate plus the applicable margin; or

         o  the adjusted LIBOR plus the applicable margin.

         The base rate for any day equals the higher of the federal funds rate
plus 1/2 of 1% or the Wachovia Bank prime rate. The applicable margin for the
revolving line of credit is as follows:

         o  where the Partnership's leverage ratio, that is, the ratio of its
            debt to earnings before interest, taxes, depreciation and
            amortization, or EBITDA, is less than or equal to 2.5, the
            applicable margin is 1.00% for base rate loans and 2.00% for LIBOR
            loans;

         o  where its leverage ratio is greater than 2.5 but less than or equal
            to 3.0, the applicable margin is 1.25% for base rate loans and 2.25%
            for LIBOR loans;

         o  where its leverage ratio is greater than 3.0 but less than or equal
            to 3.5, the applicable margin is 1.75% for base rate loans and 2.75%
            for LIBOR loans; and

         o  where its leverage ratio is greater than 3.5, the applicable margin
            is 2.25% for base rate loans and 3.25% for LIBOR loans.

         The applicable margin for the term loan is 0.75% higher for both base
rate loans and LIBOR loans.

         The credit facility requires the Partnership to maintain a ratio of
funded debt to EBITDA of not more than 4.0 to 1.0, reducing to 3.5 to 1.0 on
June 30, 2005 and an interest coverage ratio of not less than 3.0 to 1.0. In
addition, the Partnership is required to prepay the term loan with the net
proceeds of any asset sales or issuances of debt. With respect to any issuances
of equity, it is required to repay the term loan from the proceeds of such
issuances to the extent its ratio of funded debt to EBITDA exceeds 3.5 to 1.0.
The Partnership is required to pay down $560,000 in principal on the outstanding
balance of the term loan quarterly. Any prepayments of principal with proceeds
from asset or equity sales that it makes will be credited pro rata against this
repayment obligation.

         The credit agreement contains covenants customary for loans of this
size, including restrictions on incurring additional debt and making material
acquisitions, and a prohibition on paying distributions to the Partnership's
unitholders if an event of default occurs. The events which constitute an event
of default are also customary for loans of this size, including payment
defaults, breaches of the Partnership's representations or covenants contained
in the credit agreement, adverse judgments against it in excess of a specified
amount, and a change of control of its general partner.

NOTE 11 -CREDIT FACILITY - (CONTINUED)

         The Partnership had $10.0 million outstanding on its revolving credit
facility at a rate of 7.0% and $44.3 million outstanding on it term loan at a
rate of 7.75% at December 31, 2004. In addition, the Partnership had $2.2
million outstanding under letters of credit.

         Annual debt principal payments over the next five fiscal periods ending
December 31 are as follows: 2005 - $2.3 million; 2006 - $2.3 million; 2007 -
$2.3 million; 2008 - $10.6 million; 2009 - $36.9 million.

NOTE 12 - LEASES AND COMMITMENTS

         The Partnership leases equipment and office space with varying
expiration dates through 2007. Rent expense for the years ended December 31,
2004, 2003 and 2002 was $830,000, $1,039,000 and $840,000, respectively. Minimum
future lease payments for these leases in 2005, 2006 and 2007 are $944,000,
$161,000 and $41,000, respectively.

NOTE 13 - COMMITMENTS AND CONTINGENCIES

         The Partnership is a party to various routine legal proceedings arising
out of the ordinary course of its business. Management believes that none of
these actions, individually or in the aggregate, will have a material adverse
effect on the Partnership's financial condition or results of operations.

NOTE 14 - SETTLEMENT OF TERMINATED ALASKA PIPELINE ARBITRATION

         In September 2003, the Partnership entered into an agreement with SEMCO
Energy, Inc. ("SEMCO") to purchase all of the stock of Alaska Pipeline. In order
to complete the acquisition, the Partnership needed the approval of the
Regulatory Commission of Alaska. The Regulatory Commission initially approved
the transaction, but on June 4, 2004, it vacated its order of approval based
upon a motion for clarification or reconsideration filed by SEMCO. On July 1,
2004, SEMCO sent the Partnership a notice purporting to terminate the
transaction. The Partnership pursued its remedies under the acquisition
agreement. In connection with the acquisition, subsequent termination and legal
action, the Partnership incurred costs of approximately $4.0 million. On
December 30, 2004, the Partnership entered into a settlement agreement with
SEMCO settling all issues and matters related to SEMCO's termination of the sale
of Alaska Pipeline to the Partnership and SEMCO paid the Partnership $5.5
million. The Partnership recognized a gain of $1.5 million on this settlement
which is shown as Gain on arbitration settlement, net, on the Partnership's
consolidated statements of income.

NOTE 15 - LONG-TERM INCENTIVE PLAN

         The Partnership has a Long-Term Incentive Plan as discussed in Note 8.
During the year ended December 31, 2004, 59,598 phantom units were granted.
Grants for 846 units were forfeited during the three months ended June 30, 2004,
leaving 58,752 phantom units outstanding as of December 31, 2004. The
Partnership recognized $821,000 in compensation expense related to these grants
and their associated distributions in the year ended December 31, 2004. The fair
market value associated with these grants at December 31, 2004 was $2.5 million
which will be amortized into expense over the vesting period of the units.

(a) Includes revenues and expenses which do not meet the quantitative threshold
    for reporting segment information and general corporate expenses not
    allocable to any particular segment.

         Segment profit (loss) represents total revenues less costs and expenses
attributable thereto, including interest and depreciation and amortization.

         The Partnership sells natural gas and NGLs under contract to various
purchasers in the normal course of business. For the year ended December 31,
2004, Mid-Continent had two purchasers that accounted for approximately 34% and
25% of the Partnership's revenues. Additionally, two purchasers accounted for
39% and 31% of Mid-Continent's trade receivable at December 31, 2004.
Substantially all Appalachian revenues are derived from a master gas gathering
agreement with Atlas America.

NOTE 18 - SUBSEQUENT EVENTS

         On March 8, 2005 the Partnership entered into an agreement to acquire
all of the outstanding equity interests in ETC Oklahoma Pipeline, Ltd., a Texas
limited partnership for $190 million in cash and subject to certain post-closing
adjustments, including gas imbalances, certain prepaid costs and expenses and
capital expenditures, and any defects. The transaction is expected to be
completed in the second quarter of 2005 and is conditioned on the receipt of
various approvals, including Hart-Scott-Rodino Act approval and other customary
closing conditions. ETC Oklahoma Pipeline's principal assets include more than
315 miles of natural gas pipeline, a natural gas processing facility and a gas
treatment plant in western Oklahoma. The acquisition expands the Partnership
activities in the mid-continent area and provides the potential for further
growth to APLMC's operations based in Tulsa, Oklahoma.

         To finance the acquisition, the Partnership has received a commitment
from Wachovia Bank, National Association and Fleet National Bank, a Bank of
America company, to fully underwrite a new $270 million loan facility. The
facility will be comprised of a $225 million 5-year revolving loan and a $45
million 5-year term loan. The loan proceeds will be used to refinance the
existing $54 million outstanding on the partnership's current $135 million
facility and to finance the acquisition of ETC Oklahoma Pipeline.

        FINANCIAL DISCLOSURE

ITEM 9A. CONTROLS AND PROCEDURES

        MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

         The management of our General Partner is responsible for establishing
and maintaining adequate internal control over financial reporting, as such term
is defined in Exchange Act Rules 13a-15(f). Under the supervision and with the
participation of management, including our General Partner's principal executive
officer and principal financial officer, we conducted an evaluation of the
effectiveness of internal control over financial reporting based upon criteria
set forth by the Committee of Sponsoring Organizations of the Treadway
Commission in Internal Control - Integrated Framework (COSO framework).

         An effective internal control system, no matter how well designed, has
inherent limitations, including the possibility of human error and circumvention
or overriding of controls and therefore can provide only reasonable assurance
with respect to reliable financial reporting. Furthermore, effectiveness of an
internal control system in future periods can not be guaranteed because the
design of any system of internal controls is based in part upon assumptions
about the likelihood of future events. There can be no assurance that any
control design will succeed in achieving its stated goals under all potential
future conditions. Over time certain controls may become inadequate because of
changes in business conditions, or the degree of compliance with policies and
procedures may deteriorate. As such, misstatements due to error or fraud may
occur and not be detected.

         In conducting our evaluation of the effectiveness of our internal
control over financial reporting, we have excluded due to its size and
complexity the acquisition of Spectrum Field Services, Inc. which changed its
name to Atlas Pipeline Mid-Continent, ("APLMC") which was completed in July
2004. This acquisition created a second geographic location with a business line
distinct from that of our Appalachian operations in which financial reporting
will continue to occur with their own control environment, control activities
and proprietary information technology systems. Collectively, this acquisition
constituted 74% of total assets as of December 31, 2004, 76% of total revenues
and 43% of net earnings for the year then ended (See Note 6 to the consolidated
financial statements which contains further discussion of this acquisition and
its impact on our consolidated financial statements). We plan to fully integrate
our two financial reporting locations (APLMC and our existing Appalachian
operations) into a common financial reporting framework in 2005.

<PAGE>
         Based on our evaluation under the COSO framework, management concluded
that internal control over financial reporting was effective as of December 31,
2004. Management's assessment of the effectiveness of internal control over
financial reporting as of December 31, 2004 has been audited by Grant Thornton
LLP, an independent registered public accounting firm, as stated in their report
which is included herein.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


Partners
Atlas Pipeline Partners, L.P.

We have audited management's assessment, included in the accompanying
Management's Report on Internal Control over Financial Reporting, that Atlas
Pipeline Partners, L.P. ("the Partnership") maintained effective internal
control over financial reporting as of December 31, 2004, based on criteria
established in Internal Control--Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO). The Partnership's
management is responsible for maintaining effective internal control over
financial reporting and for its assessment of the effectiveness of internal
control over financial reporting. Our responsibility is to express an opinion on
management's assessment and an opinion on the effectiveness of the partnership's
internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether effective
internal control over financial reporting was maintained in all material
respects. Our audit included obtaining an understanding of internal control over
financial reporting, evaluating management's assessment, testing and evaluating
the design and operating effectiveness of internal control, and performing such
other procedures as we considered necessary in the circumstances. We believe
that our audit provides a reasonable basis for our opinion.

In conducting management's evaluation of the effectiveness of its internal
control over financial reporting, management has excluded, due to its size and
complexity, the Partnership's subsidiary, Atlas Pipeline Mid-Continent, LLC,
(formerly Spectrum Field Services, Inc.) which was recently acquired in July
2004. This acquisition created a second geographic location with a business line
distinct from that of the Partnership's Appalachian operations. Financial
reporting for this new acquisition is performed within a separate control
environment containing separate control activities and proprietary information
technology systems. Collectively, this acquisition constituted 74% of total
consolidated assets as of December 31, 2004 and 76% and 43%, respectively, of
consolidated revenues and net earnings for the year then ended. We believe that
management had sufficient cause to exclude this acquisition in its evaluation of
the effectiveness of its internal control over financial reporting based on the
size and complexity, and timing of the acquisition.

A company's internal control over financial reporting is a process designed to
provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance
with generally accepted accounting principles. A company's internal control over
financial reporting includes those policies and procedures that (1) pertain to
the maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the company; (2)
provide reasonable assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with generally accepted
accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of
the company; and (3) provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use, or disposition of the company's
assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting
may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

In our opinion, management's assessment that the Partnership maintained
effective internal control over financial reporting as of December 31, 2004, is
fairly stated, in all material respects, based on criteria established in
Internal Control--Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO). Also in our opinion, the
Partnership maintained, in all material respects, effective internal control
over financial reporting as of December 31, 2004, based on criteria established
in Internal Control--Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO).

We have also audited, in accordance with the standards of the Public Company
Accounting Oversight Board (United States), the consolidated balance sheets of
the Partnership and its subsidiaries as of December 31, 2004 and 2003, and
related consolidated statements of income, comprehensive income, partners'
capital (deficit) and cash flows for each of the three years ended December 31,
2004, and our report dated March 9, 2005 expressed an unqualified opinion on
those financial statements.

ITEM 10. DIRECTORS AND EXECUTIVE OFFICERS OF THE GENERAL PARTNER

         Our general partner manages our activities. Unitholders do not directly
or indirectly participate in our management or operation or have actual or
apparent authority to enter into contracts on our behalf or to otherwise bind
us. Our general partner will be liable, as general partner, for all of our debts
to the extent not paid, except to the extent that indebtedness or other
obligations incurred by us are specifically with recourse only to our assets.
Whenever possible, our general partner intends to make any of our indebtedness
or other obligations with recourse only to our assets.

         Three members of the managing board of our general partner who are
neither officers nor employees of our general partner nor directors, managing
board members, officers or employees of any affiliate of our general partner
(and have not been for the past five years) serve on the conflicts committee.
Messrs. Michael Bradley, Curtis Clifford and Murray Levin currently serve as the
conflicts committee of the managing board. The conflicts committee has the
authority to review specific matters as to which the managing board believes
there may be a conflict of interest in order to determine if the resolution of
the conflict proposed by our general partner is fair and reasonable to us. Any
matters approved by the conflicts committee are conclusively judged to be fair
and reasonable to us, approved by all our partners and not a breach by our
general partner or its managing board of any duties they may owe us or the
unitholders. In addition, the members of the conflicts committee also constitute
an audit committee which reviews the external financial reporting by our
management, the audit by our independent public accountants, the procedures for
internal auditing and the adequacy of our internal accounting controls. Mr.
Bradley has been designated as the audit committee financial expert by the board
of managers of the general partner, who determined that he is independent within
the meaning of Item 7(d)(3)(iv) of Schedule 14A of the Securities Exchange Act.

         As is commonly the case with publicly traded limited partnerships, we
do not directly employ any of the persons responsible for our management or
operation. Rather, Atlas America personnel manage and operate our business.
Officers of our general partner may spend a substantial amount of time managing
the business and affairs of Atlas America and its affiliates and may face a
conflict regarding the allocation of their time between our business and affairs
and their other business interests.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section 16(a) of the Securities Exchange Act of 1934 requires executive
officers and managing board members of our general partner and persons who own
more than 10% of a registered class of our equity securities to file reports of
ownership and changes in ownership with the Securities and Exchange Commission
and to furnish us with copies of all such reports. Based solely upon our review
of reports received by us, or representations that no filings were required, we
believe that all of the officers and managing board members of our general
partner complied with all applicable filing requirements during 2004, except for
one Form 4 inadvertently filed late by each of Messrs. Banks and Levin in
connection with a grant under our long-term incentive plan. We did not have any
record holders of 10% or more of our common units in 2004.

REIMBURSEMENT OF EXPENSES OF OUR GENERAL PARTNER AND ITS AFFILIATES

         Our general partner does not receive any management fee or other
compensation for its services apart from its general partner and incentive
distribution interests. We reimburse our general partner and its affiliates,
including Atlas, for all expenses incurred on our behalf. These expenses include
the costs of employee, officer and managing board member compensation and
benefits properly allocable to us, and all other expenses necessary or
appropriate to the conduct of our business. Our partnership agreement provides
that our general partner will determine the expenses that are allocable to us in
any reasonable manner determined by our general partner in its sole discretion.
Our general partner allocates the costs of employee and officer compensation and
benefits based upon the amount of business time spent by those employees and
officers on our business. We reimbursed our general partner $15.9 million for
expenses incurred and capitalized costs during 2004, which constituted all of
our transportation and compression, general and administrative costs in our
Appalachian area of operations.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

         Neither we nor the managing board of our general partner has a
compensation committee. Compensation of the personnel of Atlas America and its
affiliates who provide us with services is set by Atlas America and such
affiliates. The independent members of the managing board of our general
partner, however, do review the allocation of the salaries of such personnel for
purposes of reimbursement, discussed in "Reimbursement of Expenses of our
General Partner and Its Affiliates", above and in Item 11, "Executive
Compensation." None of the independent managing board members is an employee or
former employee of ours or of our general partner. No executive officer of our
general partner is a director or executive officer of any entity in which an
independent managing board member is a director or executive officer.

CODE OF BUSINESS CONDUCT AND ETHICS

         We have adopted a Code of Business Conduct and Ethics that applies to
the principal executive officer, principal financial officer and principal
accounting officer of our general partner, as well as to persons performing
services for us generally. This code of ethics is posted on our website at:

ITEM 11. EXECUTIVE COMPENSATION

EXECUTIVE COMPENSATION

         We do not directly compensate the executive officers of our general
partner. Rather, Atlas America and its affiliates allocate the compensation of
the executive officers between activities on behalf of our general partner and
us and activities on behalf of itself and its affiliates based upon an estimate
of the time spent by such persons on activities for us and for Atlas America and
its affiliates. We reimburse our general partner for the compensation allocated
to us. The compensation allocation was $1,081,000, $1,035,000 and $438,000 for
the years ended December 31, 2004, 2003 and 2002, respectively. The following
table sets forth the compensation allocation for the last three fiscal years for
our general partner's Chief Executive Officer and President. No other executive
officer of the general partner received an allocation of aggregate salary and
bonus in excess of $100,000 during the periods indicated.

LONG-TERM INCENTIVE PLAN

       Our general partner has adopted the Atlas Pipeline Partners, L.P.
Long-Term Incentive Plan (the "Plan") for employees and directors of our general
partner and its affiliates who perform services for us. Awards contemplated by
the Plan include phantom units and unit options. The Plan currently permits the
grant of phantom units and unit options covering an aggregate of 435,000 common
units delivered upon vesting of such phantom units or unit options. The Plan is
administered by a committee appointed by the General Partner's managing board
(the "Committee"), which sets the terms of awards under the Plan. The Committee
may make awards of either phantom units or options for an aggregate of 435,000
common units, provided that the maximum number of phantom units that may be
awarded in total to non-employee managing board members is 10,000.

         Phantom Units. A phantom unit entitles the grantee to receive, upon the
vesting of the phantom unit, a common unit (or cash equivalent, depending on the
terms of the grant). As of December 31, 2004, grants of 58,752 unvested phantom
units under the Plan remain outstanding to employees, officers and directors of
our general partner. The Committee may, in the future, make additional grants
under the plan to employees and directors containing such terms as the Committee
shall determine, including tandem distribution equivalent rights with respect to
phantom units. As a result of the vesting of these awards, we recognized an
expense of $700,000 during 2004.

       The issuance of the common units upon vesting of phantom units is
primarily intended to serve as a means of incentive compensation for
performance. Therefore, no consideration is paid to us by the plan participants
upon receipt of the common units.

       Grants of 1,752 phantom units were made in 2004 to current non-employee
directors of our general partner. These units vest and are payable in 25%
increments.

       The following table shows the vesting of phantom units granted under the
Plan during 2004 to the Named Executive Officers.

    unit.

COMPENSATION OF MANAGING BOARD MEMBERS

         Our general partner does not pay additional remuneration to officers or
employees of Atlas America who also serve as managing board members. In fiscal
year 2004 Each non-employee managing board member received an annual retainer of
$20,000 in cash and an annual grant of phantom units (1) with DERs (2) in an
amount equal to the lesser of 500 units or $15,000 worth of units (based upon
the market price of our common units) pursuant to our Long-Term Incentive Plan,
which was approved by our unitholders on February 11, 2004. In addition, our
general partner reimburses each non-employee board member for out-of-pocket
expenses in connection with attending meetings of the board or committees. We
reimburse our general partner for these expenses and indemnify our general
partner's managing board members for actions associated with serving as managing
board members to the extent permitted under Delaware law.

                                      -70-

(1) A phantom unit is one which, upon vesting, entitles the holder to receive a
    common unit or its then fair market value in cash, as specified in the
    grant.

(2) A right, granted in tandem with a specific phantom unit, to receive an
    amount in cash equal to, and at the same time as, the cash distributions

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         At December 31, 2004, our general partner owned 1,641,026 subordinated
units constituting 23% of the limited partner interest in us. Our general
partner also owns, through its 1.0101% general partnership interest in us and
1.0101% general partnership interest in our operating subsidiary, Atlas Pipeline
Operating Partnership, a 2% general partner interest in our consolidated
pipeline operations. We paid our general partner distributions totaling $6.4
million in 2004 in respect of these interests.

         Our omnibus agreement and the natural gas gathering agreements with
Atlas America and its affiliates were not the result of arms-length negotiations
and, accordingly, we cannot assure you that we could have obtained more
favorable terms from independent third parties similarly situated. However,
since these agreements principally involve the imposition of obligations on
Atlas America and its affiliates, we do not believe that we could obtain similar
agreements from independent third parties.

         In connection with the acquisition of Spectrum described in Item 1,
"Business - General," and Item 7, "Management's Discussion and Analysis of
Financial Condition and Results of Operations", we entered into commitment
agreements with Resource America and Atlas America for the purchase by them of
up to $25.0 million of preferred units in Atlas Pipeline Operating Partnership,
L.P., our subsidiary. In consideration for their commitments, upon the closing
of the Spectrum acquisition and the purchase by each of $10.0 million preferred
units, we paid Resource America and Atlas America commitment fees of $750,000
and $500,000, respectively.

         In connection with the proposed acquisition of Alaska Pipeline Company,
L.L.C. we paid Resource America a fee of $70,750 in the year ended December 31,
2004 for its commitment to repay certain financing that would have been required
to complete the acquisition.

         We do not currently directly employ any persons to manage or operate
our business. These functions are provided by employees of Atlas America and/or
its affiliates. As discussed in Items 10 and 11, we reimburse our general
partner, Atlas America and its affiliates for expenses they incur in managing
our operations and for an allocation of the compensation paid to the executive
officers of our general partner.

ITEM 14.  PRINCIPAL ACCOUNTANT FEES AND SERVICES

         Aggregate fees recognized by us during the years ending December 31,
2004 and 2003 by its principal accounting firm, Grant Thornton LLP are set
forth below.
