PART I

ITEM 1.  DESCRIPTION OF BUSINESS

General. We were formed as a Delaware limited partnership on July 25, 2005, with Atlas Resources, Inc. as our Managing General Partner, or MGP, to drill natural gas development wells. We drilled and currently operate wells located in Pennsylvania and Tennessee. We have no employees and rely on our MGP for management, which, in turn, relies on its parent company, Atlas Energy Resources, LLC (NYSE:ATN), or Atlas Energy, for administrative services. See Item 10 “Directors, Executive Officers and Corporate Governance”.

We received total cash subscriptions from investors of $52,245,700, which were paid to our MGP acting as operator and general drilling contractor under our drilling and operating agreements. Our MGP contributed leases and paid all syndication and offering costs and has contributed 66.26% of the tangible (“equipment”) costs for a total capital contribution of $24,244,700. We have drilled 188 developmental wells to the Clinton/Medina, Upper Devonian Sandstones and Southern Appalachia Shale geological formations in Pennsylvania and Tennessee.

Atlas Resources Inc. Merged into Atlas Resources, LLC.  In March 2006,Atlas Resources, Inc., our MGP was merged into a newly-formed limited liability company, Atlas Resources, LLC, which became an indirect subsidiary of Atlas Energy, a newly-formed subsidiary of Atlas America, Inc., or Atlas America.  Atlas Resources, LLC serves as our MGP.

Public Offering of Atlas Energy.  In December 2006, Atlas America contributed substantially all of its natural gas and oil assets and its investment partnership management business to Atlas Energy.  Concurrent with this transaction, Atlas Energy issued 7,273,750 common units, representing a 19.4% ownership interest at that moment, in an initial public offering at a price of $21.00 per unit.  The net proceeds of approximately $139.9 million, after underwriting discounts and commissions, were distributed to Atlas America.

Atlas Energy is a limited liability company focused on the development and production of natural gas and, to a lesser extent, oil in northern Michigan's Antrim Shale and the Appalachian Basin region of the United States of America. Atlas Energy is also a leading sponsor of and manages tax-advantaged direct investment partnerships, in which it coinvests to finance the exploitation and development of its acreage.Atlas Energy is managed by Atlas Energy Management, Inc., through which Atlas America provides Atlas Energy with the personnel necessary to manage its assets and raise capital.

Business Strategy.  Our wells are currently producing natural gas and, to a far lesser extent, oil which are our only products.  Most of our gas is gathered and delivered to market through Atlas Pipeline Partners L.P.’s gas gathering system which is managed by an affiliate of our MGP.  We do not plan to sell any of our wells and will continue to produce them until they are depleted or become uneconomical to produce, at which time they will be plugged and abandoned or sold.  No other wells will be drilled and no additional funds will be required for drilling.  See Item 2 “Description of Properties” for information concerning our wells.

3

Our ongoing operating and maintenance costs have been and are expected to be fulfilled through revenues from the sale of our natural gas and oil production.  We pay our MGP a monthly well supervision fee of $296 per well, as outlined in our drilling and operating agreement.  This well supervision fee covers all normal and regularly recurring operating expenses for the production and sale of natural gas and, to a lesser extent, oil such as:

·   well tending, routine maintenance and adjustment;

·   reading meters, recording production, pumping, maintaining appropriate books and records; and

·   preparing reports to us and to government agencies.

The well supervision fees, however, do not include costs and expenses related to the purchase of certain equipment, materials and brine disposal.  If these expenses are incurred, we pay at cost for third-party services, materials, and a reasonable charge for services performed directly by our MGP or its affiliates.  Also, beginning one year after each of our wells has been placed into production our MGP, as operator, may retain $200 per month per well to cover the estimated future plugging and abandonment costs of the well.  At December 31, 2008, our MGP had not withheld any funds for this purpose.

Markets and Competition.  The availability of a ready market for natural gas and oil produced by us, and the price obtained, depends on numerous factors beyond our control, including the extent of domestic production, imports of foreign natural gas and oil, political instability or terrorist acts in oil and gas producing countries and regions, market demand, competition from other energy sources, the effect of federal regulation on the sale of natural gas and oil in interstate commerce, other governmental regulation of the production and transportation of natural gas and oil and the proximity, availability and capacity of pipelines and other required facilities.  Our MGP is responsible for selling our natural gas production. Our natural gas is sold as discussed in Item 2 “Description of Properties.” During 2008 and 2007, we experienced no problems in selling our natural gas and oil. Product availability and price are the principal means of competition in selling natural gas and oil production.

While it is impossible to accurately determine our comparative position in the industry, we do not consider our operations to be a significant factor in the industry.  See Item 2 “Description of Properties” regarding the marketing of our natural gas and oil.

Governmental Regulation.  The energy industry in general is heavily regulated by federal and state authorities, including regulation of production, environmental quality and pollution control.  The intent of federal and state regulations generally is to prevent waste, protect rights to produce natural gas and oil between owners in a common reservoir and control contamination of the environment.  Failure to comply with regulatory requirements can result in substantial fines and other penalties.  The following discussion of the regulation of the United States of America energy industry is not intended to constitute a complete discussion of the various statutes, rules, regulations and environmental orders to which our operations may be subject.

Regulation of oil and gas producing activities.  State regulatory agencies where a producing natural gas well is located provide a comprehensive statutory and regulatory scheme for oil and gas operations such as ours including supervising the production activities and the transportation of natural gas sold in intrastate markets.  Our oil and gas operations in Pennsylvania are regulated by the Department of Environmental Resources, Division of Oil and Gas, our oil and gas operations in Tennessee are regulated by the Tennessee Department of Environment and Conservation and the Division of Geology.

4

Among other things, the regulations involve:

·   new well permit and well registration requirements, procedures and fees;

·   minimum well spacing requirements;

·   restriction on well locations and underground gas storage;

·   certain well site restoration, groundwater protection and safety measures;

·   landowner notification requirements;

·   certain bonding or other security measures;

·   various reporting requirements;

·   well plugging standards and procedures; and

·   broad enforcement powers.

Environmental and Safety Regulation.  Under the Comprehensive Environmental Response, Compensation and Liability Act, the Toxic Substances Control Act, the Resource Conservation and Recovery Act, the Oil Pollution Act of 1990, the Clean Air Act, and other federal and state laws relating to the environment, owners and operators of wells producing natural gas or oil can be liable for fines, penalties and clean-up costs for pollution caused by the wells. Moreover, the owners or operators’ liability can extend to pollution costs from situations that occurred prior to their acquisition of the assets.  State public utility regulators have either adopted federal standards or promulgated their own safety requirements consistent with the federal regulations.

We believe we have complied in all material respects with applicable federal and state regulations and do not expect that these regulations will have a material adverse impact on our operations. Our producing activities also must comply with various federal, state and local laws not mentioned, including those covering the discharge of materials into the environment, or otherwise relating to the protection of the environment.

Where can you find more information.  We will file Form 10-K Annual Report and Form 10-Q Quarterly Reports as well as other non-recurring special purpose reports with the Securities and Exchange Commission.  A complete list of our filings is available on the Securities and Exchange Commission’s website at www.sec.gov. Any of our filings are also available at the SEC's Public Reference Room at 100 F Street, N.E., Washington, D.C. 20549. The Public Reference Room may be contacted at 1-800- SEC-0330 for further information.

Additionally, our MGP will provide copies of any of these reports to you without charge.  Such requests should be made to:

ITEM 2.  DESCRIPTION OF PROPERTIES

Drilling Activity.  For the years ended December 31, 2008 and 2007, we did not drill any wells nor do we expect to do so in future years.

Summary of Producing Wells.  The table below shows the number of producing gross and net wells at December 31, 2008, in which we have a working interest. All wells are located in the Appalachian Basin.

	Number of Producing Wells
	Gross		Net
Gas		186		180.5

5

Production.  The following table shows the quantities of natural gas and oil we produced (net to our interest), our average sales price, and our average production (lifting) cost per equivalent unit of production for the periods indicated.

									Average
Year									Production Cost
Ended	Production				Average Sales Price				(Lifting Cost)
December 31,	Oil (bbls) (1)		Gas (mcf) (1)		per bbl (1)		per mcf (1)		per mcfe (1) (2)
2008		3,000		923,600	$	90.42	$	9.40	$	2.18
2007		3,700		1,460,000	$	60.00	$	8.90	$	1.76

____________

(1)   “Mcf” means one thousand cubic feet of natural gas.  “Mcfe” means a thousand cubic feet equivalent.  Oil production is converted to mcfe at the rate of six mcf per barrel (“bbl”).

(2)   Lifting costs include labor to operate the wells and related equipment, repairs and maintenance, materials and supplies, property taxes, insurance and gathering charges.

Natural Gas and Oil Reserve Information.  The following table summarizes information regarding our estimated proved natural gas and oil reserves as of the date indicated. All of our reserves are located in the United States of America. Our estimates relating to our proved natural gas and oil reserves and our future net revenues from natural gas and oil reserves are based on reports which are reviewed by our independent third-party consultant as discussed below.  In accordance with SEC guidelines, we provide PV-10 estimate of future net cash flows from proved reserves discounted using an annual discount rate of 10%. The estimated future net cash flows from proved reserves are calculated using natural gas and oil sales prices in effect as of the dates of the estimates, which are held constant throughout the life of the properties.  We based our estimates of proved reserves on the following year-end weighted average prices:

	December 31,
	2008		2007
Natural gas (per mcf)	$	6.47	$	7.60
Oil (per bbl)		36.00		88.80

Reserve estimates are imprecise and may change as additional information becomes available. Furthermore, estimates of natural gas and oil reserves are projections based on engineering data. There are uncertainties inherent in the interpretation of this data as well as the projection of future rates of production. Reservoir engineering is a subjective process of estimating underground accumulations of natural gas and oil that cannot be measured in an exact way and the accuracy of any reserve estimate is a function of the quality of available data and of engineering and geological interpretation and judgment. Reserve reports of other engineers might differ from the reports of Wright & Company, our independent consultants. The results of drilling, testing and production of a well subsequent to the date of the reserve estimate for the well may justify revising the estimate of the well’s reserves in the future. Also, future prices we receive from the sale of natural gas and oil may be different from those estimated by Wright & Company in preparing the reserve reports.  The amounts and timing of future operating costs also may differ from those we estimated. In addition, you should not construe the estimated PV-10 values as representative of the fair market value of our proved natural gas and oil properties.  PV-10 values are based on projected cash inflows, which do not provide for changes in natural gas and oil prices or for escalation of expenses. The meaningfulness of these estimates depends on the accuracy of the assumptions on which they were based. The downward revision of oil and gas reserves reflected production results that occurred during 2008 and used historical field level and historical decline curves for the year ended December 31, 2008. This decline reflects a decrease in the average price of natural gas of 15% and the average price of oil of 59% for the year ended December 31, 2008.

6

We evaluate natural gas reserves at constant temperature and pressure.  A change in either of these factors can affect the measurement of natural gas reserves. We deducted when applicable, operating costs, development costs and production-related and ad valorem taxes in arriving at the estimated future cash flows.  We made no provision for income taxes, and based the estimates on operating methods and conditions prevailing as of the dates indicated.  We cannot assure you that these estimates are accurate predictions of future net cash flows from our natural gas and oil reserves or their present value. For additional information concerning our natural gas and oil reserves and estimates of future net revenues, see Note 9 of the “Notes to Financial Statements” in Item 8 “Financial Statements.”

Undiscounted estimate per limited partner unit (5)	$	3,051	$	6,025

_____________

(1)   “Proved reserves” generally means the estimated quantities of crude oil, natural gas, and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions, i.e., prices and costs as of the date the estimate is made. Prices include consideration of changes in existing prices provided only by contractual arrangements, but not on escalations based upon future conditions.  Reservoirs are considered proved if economic production is supported by either actual production or conclusive formation test.  The area of a reservoir considered proved includes:  that portion delineated by drilling and defined by gas-oil and/or oil-water contacts, if any, and the immediately adjoining portions not yet drilled, but which can be reasonably judged as economically productive on the basis of available geological and engineering data.

(2)   “Proved developed reserves” generally means reserves that can be expected to be recovered through existing wells with existing equipment and operating methods.

(3)   The present value of estimated future net cash flows is calculated by discounting estimated future net cash flows by 10% annually.

(4)   Please see Regulation S-X rule 4-10 for complete definitions of each reserve category.

(5)   This value per $10,000 unit is determined by following the methodology used for determining our proved reserves using the data discussed above. However, this value does not necessarily reflect the fair market value of a unit, and each unit is illiquid. Also, the value of a unit for purposes of presentment of the unit to our MGP for purchase is different because it is calculated under a formula set forth in the partnership agreement.

We have not filed any estimates of our gas and oil reserves with, nor were such estimates included in any reports to, any Federal or foreign governmental agency other than the SEC within the 12 months before the date of this filing.

7

Title to Properties.  We believe that we hold good and indefeasible title to our properties in accordance with standards generally accepted in the natural gas industry, subject to exceptions stated in the opinions of counsel employed by us in the various areas in which we conduct our activities.  We do not believe that these exceptions detract substantially from our use of any property.  As is customary in the natural gas industry, our MGP conducts only a perfunctory title examination at the time it acquires a property.  Before our MGP commences drilling operations, it conducts an extensive title examination and performs curative work on defects that it deems significant. Our MGP has obtained title examinations for substantially all of our producing properties. No single property represents a material portion of our holdings.

Our properties are subject to royalty, overriding royalty and other outstanding interests customary in the natural gas industry. Our properties are also subject to burdens such as liens incident to operating agreements, taxes, development obligations under natural gas and oil leases, farm-out arrangements and other encumbrances, easements and restrictions. We do not believe that any of these burdens will materially interfere with our use of our properties.

Acreage.  The table below shows, by state, the estimated acres of developed oil and gas acreage in which we had an interest at December 31, 2008.  There was no undeveloped acreage at December 31, 2008.

	Developed Acreage
Location	Gross (1)		Net (2)
Pennsylvania		3,786.47		3,733.10
Tennessee		800.00		740.00
Total		4,586.47		4,473.10

_____________

(1)   A “gross” acre is an acre in which we own a working interest.

(2)   A “net” acre equals the actual working interest we own in one gross acre divided by one hundred. For example, a 50% working interest in an acre is one gross acre, but a 0.5 net acre.

Delivery Commitments.  Atlas Energy markets our natural gas which is principally located in the Fayette County, PA area, primarily to UGI Energy Services, Inc., Conoco Phillips Company, Exelon Energy Company, Colonial Energy, Inc. Equitable Gas and to third-party natural gas purchasers or marketers.

The pricing arrangements with UGI Energy Services, Inc., Conoco Phillips Company and other third-party gas purchasers or marketers are tied to the New York Mercantile Exchange Commissions or NYMEX monthly futures contract price. The total price received for our gas is a combination of the monthly NYMEX futures price plus a basis adjustment.  For example, the NYMEX futures price is the base price and there is an additional premium paid, because of the location of the gas (the Appalachian Basin) in relation to the gas market, which is referred to as the “basis.”

Pricing for natural gas and oil has been volatile and uncertain for many years. The agreements with UGI Energy Services, Inc. and Conoco Phillips Company, and the other third-party gas purchasers or marketers also permit Atlas Energy and its affiliates to implement gas forward sales transactions through those companies. UGI Energy Services, Inc., Conoco Phillips Company, and the other third-party purchasers or marketers also use NYMEX based financial instruments to hedge their pricing exposure and make price-hedging opportunities available to Atlas Energy, which then makes those arrangements available to us and its other partnerships. The price paid by UGI Energy Services, Inc., Conoco Phillips Company, and any other third-party purchasers for certain volumes of natural gas sold under these hedge agreements may be significantly different from the underlying monthly spot market price. Also, Atlas Energy's hedges may include purchases of regulated NYMEX futures and options contracts and non-regulated over-the-counter futures contracts with qualified counterparties. The futures contracts employed by Atlas Energy are commitments to purchase or sell natural gas at future dates and generally cover one-month periods for up to six years in the future. The overall portion of our natural gas and oil portfolio that is hedged changes from time to time. 

8

To assure that all financial instruments will be used solely for hedging price risks and not for speculative purposes, Atlas Energy has established a committee to assure that all financial trading is done in compliance with Atlas Energy’s hedging policies and procedures. Atlas Energy does not intend to contract for positions that it cannot offset with actual production.

We are not required to provide any fixed and determinable quantities of gas under any agreement other than with Conoco Phillips Company, UGI Energy Services, Inc. and the other third-party gas purchasers or marketers.

ITEM 3.  LEGAL PROCEEDINGS

The MGP is not aware of any legal proceedings filed against us.

Affiliates of the MGP and their subsidiaries are party to various routine legal proceedings arising in the ordinary course of their collective business. The MGP management believes that none of these actions, individually or in the aggregate, will have a material adverse effect on the MGP's financial condition or results of operations.

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

None

PART II

ITEM 5.  MARKET FOR REGISTRANT’S COMMON EQUITY AND RELATED SECURITY HOLDER MATTERS

Market Information.  There is no established public trading market for our units and we do not anticipate a market for our units will develop.  Our units may be transferred only in accordance with the provisions of Article VI of our partnership agreement which require that:

·   our managing general partner consent;

·   the transfer not result in materially adverse tax consequences to us; and

·   the transfer not violate federal or state securities laws.

An assignee of a unit may become a substituted partner only on meeting the following conditions:

·   the assignor gives the assignee the right;

·   our managing general partner consents to the substitution;

·   the assignee pays to us all costs and expenses incurred in connection with the substitution; and

·   the assignee executes and delivers the instruments, which our managing general partner requires to effect the substitution and to confirm his or her agreement to be bound by the terms of our partnership agreement.

9

A substitute partner is entitled to all of the rights of full ownership of the assigned units, including the right to vote.

Holders.  As of December 31, 2008, we had 1,632 unit holders.

Distributions. Our MGP will review our accounts monthly to determine whether cash distributions are appropriate and the amount to be distributed, if any.  We will distribute those funds, which our MGP determines are not necessary for us to retain, to our partners.  We will not advance or borrow funds for purposes of making distributions.

The determination of our revenues and costs is made in accordance with generally accepted accounting principles, consistently applied, and cash distributions to our MGP may only be made in conjunction with distributions to our limited partners.

During the years ended December 31, 2008 and 2007, we distributed the following:

·   $5,215,400 and $7,649,200 to our limited partners; and

·   $2,560,900 and $4,315,800 to our managing general partner, respectively.

ITEM 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION OR PLAN OF OPERATIONS

This Item 7 “Management’s Discussion and Analysis of Financial Condition or Plan of Operations” should be read in conjunction with Item 8 “Financial Statements” and the “Notes to Financial Statements”.

General. We were formed as a Delaware limited partnership on July 25, 2005, with Atlas Resources, Inc. as our Managing General Partner, or MGP, to drill natural gas developmental wells. We do not plan to sell any of our wells and will continue to produce them until they are depleted or become uneconomical to produce at which time they will be plugged and abandoned or sold. No additional funds will be required for drilling.

Atlas Resources Inc. Merged into Atlas Resources, LLC.  In March 2006, our MGP was merged into a newly-formed limited liability company, Atlas Resources, LLC, which became an indirect subsidiary of Atlas Energy Resources, LLC, (NYSE:ATN), or Atlas Energy, a newly-formed subsidiary of Atlas America, Inc., or Atlas America. Atlas Resources, LLC now serves as our MGP.

Public Offering of Atlas Energy.  In December 2006, Atlas America contributed substantially all of its natural gas and oil assets and its investment partnership management business to Atlas Energy Resources, LLC.  Concurrent with this transaction, Atlas Energy issued 7,273,750 common units, representing a 19.4% ownership interest at that moment, in an initial public offering at a price of $21.00 per unit. The net proceeds of approximately $139.9 million, after underwriting discounts and commissions, were distributed to Atlas America.

Atlas Energy is a limited liability company focused on the development and production of natural gas and, to a lesser extent, oil in northern Michigan's Antrim Shale and the Appalachian Basin region of the United States of America. Atlas Energy is also a leading sponsor of and manages tax-advantaged direct investment partnerships, in which it coinvests to finance the exploitation and development of its acreage.Atlas Energy is managed by Atlas Energy Management, Inc., through which Atlas America provides Atlas Energy with the personnel necessary to manage its assets and raise capital.

____________

(1)   “Mcf” means thousand cubic feet, “mcfe” means thousand cubic feet equivalent and “bbls” means barrels.  Bbls are converted to mcfe using the ratio of six mcfs to one bbl.

(2)   The average sales price per mcf before the effects of hedging was $9.72 and $7.64 for the years ended December 31, 2008 and 2007, respectively.

(3)   The average sales price per bbl before the effects of hedging was $92.40 for the year ended December 31, 2008. There was no hedging for oil in 2007.

Natural Gas Revenues.  Our natural gas revenues were $8,680,200 and $12,995,300 for the years ended December 31, 2008 and 2007, respectively, a decrease of $4,315,100 (33%). This decrease was due to a decrease in production volumes to a 2,524 mcf per day for the year ended December 31, 2008 from 4,000 mcf per day for the year ended December 31, 2007, a decrease of 1,476 mcf per day (37%), partially offset by an increase in the average sales price we received for our natural gas to $9.40 per mcf for the year ended December 31, 2008 from $8.90 per mcf for the year ended December 31, 2007, an increase of $.50 per mcf (6%). The $4,315,100 decrease in our natural gas revenues for the year ended December 31, 2008, as compared to the prior year similar period, was attributable to a $4,774,300 decrease due to lower production volumes, and a $459,200 increase due to higher natural gas sales prices, which are driven by market conditions. The overall decrease in natural gas production volumes resulted from the normal decline inherent in the life of the well.

The price we receive for our natural gas is primarily a result of the index-driven agreements with Hess Corporation, UGI Energy Services, Inc. and our other natural gas purchasers. See Item 2 “Description of Properties.” Thus, the price we receive for our natural gas may vary significantly each month as the underlying index changes in response to market conditions.

Oil Revenues. We drill wells primarily to produce natural gas, rather than oil, but some wells have oil production.  Our oil revenues were $271,000 and $222,600 for the years ended December 31, 2008 and 2007, respectively, an increase of $48,400 (22%).  This increase was due to an increase in the average sales price we received for our oil to $90.42 for the year ended December 31, 2008 as compared to $60.00 for the year ended December 31, 2007, an increase of $30.42 per bbl (51%), partially offset by a decrease in the production volumes to 8 bbls per day for the year ended December 31, 2008 from 10 bbls per day for the year ended December 31, 2007, a decrease of 2 bbls per day (20%). The $48,400 increase in oil revenue for the year ended December 31, 2008 as compared to the prior year similar period was attributable to a $91,100 increase due to higher oil prices partially offset by a $42,700 decrease due to lower production volumes.

11

Expenses.  Production expenses were $2,052,000 and $2,607,400 for the years ended December 31, 2008 and 2007, respectively, a decrease of $555,400 (21%). This decrease was primarily due to lower variable expenses and transportation fees charged for the year ended December 31, 2008 as compared to the prior year similar period.

Depletion of our oil and gas properties as a percentage of oil and gas revenues was 50% for the years ended December 31, 2008 and December 31, 2007.

Impairment of oil and gas properties for year the ended December 31, 2008 was $24,849,500. There was no impairment of oil and gas properties for the year ended December 31, 2007. Annually, we compare the carrying value of our proved developed oil and gas producing properties to their estimated fair market value. To the extent our carrying value exceeds the estimated fair market value, an impairment charge is recognized. As a result of this assessment, an impairment charge was recognized for the year ended December 31, 2008. This impairment charge is based on reserve quantities, future market values and our carrying value. We can not provide any assurance that similar charges may or may not be taken in future periods.

General and administrative expenses were $244,900 and $270,400 for the years ended December 31, 2008 and 2007, respectively, a decrease of $25,500 (9%). These expenses include outside costs for services, as well as the monthly administrative fee charged by our MGP. This decrease was primarily due to lower third-party costs as compared to prior year similar period.

Liquidity and Capital Resources.  Cash provided by operating activities decreased $3,987,200 for the year ended December 31, 2008 to $7,490,200 as compared to $11,477,400 for the year ended December 31, 2007. This decrease was due to a decrease in net earnings before depletion, impairment and accretion of $1,181,200, and a decrease in the change in accrued liabilities of $29,600. In addition, there was a decrease in the change in accounts receivable-affiliate of $146,700 and a non-cash gain on derivative value of $2,629,700.

Cash used in financing activities decreased $4,188,800 during the year ended December 31, 2008 to $7,776,300 from $11,965,100 for the year ended December 31, 2007. This decrease was due to lower distributions to partners.

The MGP may withhold funds for future plugging and abandonment costs.  Any additional funds, if required, will be obtained from production revenues or borrowings from our MGP or its affiliates, which are not contractually committed to make loans to us. The amount that we may borrow may not at anytime exceed 5% of our total subscriptions, and we will not borrow from third-parties.

We believe future cash flows from operations and amounts available from borrowings from our MGP or its affiliates will be adequate to fund our operations.

Critical Accounting Policies.  The discussion and analysis of our financial condition and results of operations are based upon our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America.  On an on-going basis, we evaluate our estimates, including those related to our asset retirement obligations, depletion, impairment of long-lived assets, and certain accrued receivables and liabilities.  We base our estimates on historical experience and on various other assumptions that we believe reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

12

For a detailed discussion on the application of policies critical to our business operations and other accounting policies, see Note 2 of the “Notes to Financial Statements” in Item 8 “Financial Statements.”

Use of Estimates.  Preparation of our financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues, costs and expenses during the reporting period. Actual results could differ from these estimates.

Reserve Estimates.  Our estimates of our proved natural gas reserves and oil reserves and future net revenues from them, will be based on reserve analyses that rely on various assumptions, including those required by the SEC, as to natural gas prices, drilling and operating expenses, capital expenditures, abandonment costs, taxes and availability of funds.  Any significant variance in these assumptions could materially affect the estimated quantity of our reserves. As a result, our estimates of our proved natural gas reserves will be inherently imprecise.  Actual future production, natural gas prices, revenues, taxes, development expenditures, operating expenses and quantities of recoverable natural gas reserves may vary substantially from our estimates, or estimates contained in the reserve reports.  In addition, our proved reserves may be subject to downward or upward revision based on production history, results of future exploration and development, prevailing natural gas prices, mechanical difficulties, governmental regulation and other factors, many of which are beyond our control.

Accounts Receivable and Allowance for Possible Losses.  The MGP engages in credit extension, monitoring, and collection. In evaluating our allowance for possible losses, the MGP performs ongoing credit evaluations of our customers and adjusts credit limits based upon payment history and the customer’s current creditworthiness, as determined by our review of our customer’s credit information. The MGP extends credit on an unsecured basis to many of our energy customers. At December 31, 2008 and 2007 our credit evaluation indicated that the MGP has no need for an allowance for possible losses for our oil and gas receivables.

Impairment of Oil and Gas Properties. We review our producing oil and gas properties for impairment on an annual basis and whenever events and circumstances indicate a decline in the recoverability of their carrying values.  We estimate the expected future cash flows from our oil and gas properties and compare such future cash flows to the carrying amount of the oil and gas properties to determine if the carrying amount is recoverable.  If the carrying amount exceeds the estimated undiscounted future cash flows, we will adjust the carrying amount of the oil and gas properties to their fair value in the current period.  The factors used to determine fair value include, but are not limited to, estimates of reserves, future production estimates, anticipated capital expenditures, and a discount rate commensurate with the risk associated with realizing the expected cash flows projected.  Given the complexities associated with oil and gas reserve estimates and the history of price volatility in the oil and gas markets, events may arise that will require us to record an impairment of our oil and gas properties.  During 2008, we recognized an impairment charge of $24,849,500, net of an offsetting gain in other comprehensive income of $2,520,200. There was no impairment charge for the year ended December 31, 2007.

Derivative Instruments.  Atlas Energy on our behalf from time to time enters into natural gas future option and collar contracts to hedge exposure to changes in natural gas prices. At any point in time, such contracts may include regulated NYMEX futures, and options contracts and non-regulated over-the-counter futures contracts with qualified counterparties. NYMEX contracts are generally settled with offsetting positions, but may be settled by the delivery of natural gas. Oil contracts are based on a West Texas Intermediate or WTI index. These contracts have qualified and been designated as cash flow hedges and recorded at their fair values.

We apply the provisions of SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, or 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. See Note 7 on our financial statements.

13

At December 31, 2008, Atlas Energy had allocated open natural gas futures contracts to us related to natural gas sales covering 1,810,300 dekatherms (“Dth”) of gas, maturing through December 31, 2013 at an average settlement price of $8.22 per Dth. In addition, Atlas Energy had allocated oil futures contracts to us related to oil sales covering 2,400 barrels (“Bbls”) of oil, maturing through April 30, 2013 at an average settlement price of $98.31 per Bbl. At December 31, 2008, we reflected a net hedge asset on our Balance Sheets of $2,520,200. Due to the impairment of our oil and gas properties at December 31, 2008 and prior period, a net offsetting unrealized gain of $2,520,200 and $330,800, respectively, was reclassified into earnings from accumulated other comprehensive income. At December 31, 2008, a reclassification remains from a prior period in accumulated other comprehensive loss of $57,700. Of the $57,700 net loss in accumulated other comprehensive loss at December 31, 2008, if the fair values of the instruments remain at current market values, we will reclassify $53,600 of net losses to our Statements of Operations over the next twelve month period as these contracts expire, and $4,100 of net losses in later periods.  Actual amounts that will be reclassified will vary as a result of future price changes. We realized losses of $306,600 and gains of $1,842,100 for the years ended December 31, 2008 and 2007, respectively in our oil and gas revenues within the Statements of Operations related to the settlement of qualifying hedge instruments. Ineffective hedge gains or losses are recorded within the Statements of Operations while the hedge contract is open and may increase or decrease until settlement of the contract. We recognized no gains or losses during the years ended December 31, 2008 and 2007 for hedge ineffectiveness or as a result of the discontinuance of cash flow hedges.

As of December 31, 2008, Atlas Energy had allocated to us the following natural gas and oil volumes hedged:

Fair Value of Financial Instruments

We have adopted the provisions of SFAS 157 at January 1, 2008. SFAS 157 establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. SFAS 157’s hierarchy defines three levels of inputs that may be used to measure fair value:

Level 1– Quoted prices in active markets for identical assets and liabilities that the reporting entity has the ability to access at the measurement date.

Level 2– Inputs other than quoted prices included within Level 1 that are observable for the asset and liability or can be corroborated with observable market data for substantially the entire contractual term of the asset or liability.

Level 3– Unobservable inputs that reflect the entity's own assumptions about the assumptions that market participants would use in the pricing of the asset or liability and are consequently not based on market activity, but rather through particular valuation techniques.

We use the fair value methodology outlined in SFAS 157 to value the assets and liabilities for our outstanding derivative contracts. All of our derivatives contracts are defined as Level 2. Our natural gas and crude oil derivative contracts are valued based on prices quoted on the NYMEX or WTI and adjusted by the respective counterparty using various assumptions including quoted forward prices, time value, volatility factors, and contractual prices for the underlying instruments. In accordance with SFAS 157, the following table represents our fair value hierarchy for our financial instruments at December 31, 2008.

	Fair Value Measurements at December 31, 2008 Using
	Quoted prices		Significant other		Significant
	in active		observable		unobservable
	markets		inputs		inputs

Commodity-based derivatives	$	—	$	2,520,200	$	—
Total	$	—	$	2,520,200	$	—

Revenue Recognition.  Revenues from sales of natural gas and oil are recognized by us when the gas and oil have been delivered to the purchaser. Our natural gas and oil is sold under various contracts entered into by our MGP.  Virtually all of our MGP’s contract pricing provisions are tied to a market index, with certain adjustments based on, among other factors, whether a well delivers to a gathering or transmission line, quality of natural gas and prevailing supply and demand conditions, so that the price we receive from the sale of our natural gas fluctuates to remain competitive with generally available natural gas supplies in the market.

Asset Retirement Obligations.  On an annual basis, we estimate the costs of future dismantlement, restoration, reclamation and abandonment of our natural gas and oil-producing properties. We also estimate the salvage value of equipment recoverable upon abandonment. We comply with SFAS No. 143 Accounting for Asset Retirement Obligations as discussed in Note 8 to our financial statements. As of December 31, 2008 and 2007, our estimate of salvage values was greater than or equal to our estimate of the costs of future dismantlement, restoration, reclamation and abandonment. A decrease in salvage values or an increase in dismantlement, restoration, reclamation and abandonment costs from those we have estimated, or changes in our estimates or cost, would reduce our net earnings.

Off-Balance Sheet Arrangements.  We have no financial statement risk, or any Off-Balance Sheet Arrangements or contractual obligations.

Recently Issued Financial Accounting Standards

In May 2008, the Financial Accounting Standards Board, or FASB, issued Statement of Financial Accounting Standards, No. 162, The Hierarchy of Generally Accepted Accounting Policies, or SFAS 162, which reorganizes the GAAP hierarchy. The purpose of the new standard is to improve financial reporting by providing a consistent framework for determining what accounting principles should be used when preparing U.S. GAAP financial statements. The standard is effective 60 days after the SEC's approval of the PCAOB's amendments to AU Section 411. The adoption of SFAS 162 will not have an impact on our financial position or results of operations.

In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities, or SFAS 161, an amendment of FASB Statement No. 133, Accounting for Derivative Instruments and Hedging Activities, or SFAS 133. SFAS 161 requires entities to provide qualitative disclosures about the objectives and strategies for using derivatives, quantitative data about the fair value of and gains and losses on derivative contracts, and details of credit-risk-related contingent features in their hedged positions. The standard is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged, but not required. SFAS 161 also requires entities to disclose more information about the location and amounts of derivative instruments in financial statements; how derivatives and related hedges are accounted for under SFAS 133 and how the hedges affect the entity’s financial position, financial performance, and cash flows. We will apply the requirements of SFAS No. 161 on its adoption on January 1, 2009. We do not expect it to have an impact on our financial position or results of operations.

In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159, The Fair Value Option for Financial Assets and Financial Liabilities, or SFAS No. 159. SFAS No. 159 permits entities to choose to measure eligible financial instruments and certain other items at fair value. The objective is to improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. By electing the fair value option in conjunction with a derivative, an entity can achieve an accounting result similar to a fair value hedge without having to comply with complex hedge accounting rules. The statement was effective for us as of January 1, 2008. We adopted SFAS No. 159 at January 1, 2008, and have elected not to apply the fair value option to any of our financial instruments not already carried at fair value in accordance with other accounting standards, and therefore the adoption of SFAS No. 159 did not impact our financial statements for the year ended December 31, 2008.

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157, Fair Value Measurement , or SFAS No. 157. SFAS No. 157 addresses the need for increased consistency in fair value measurements, defining fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. It also establishes a framework for measuring fair value and expands disclosure requirements. In February 2008, the FASB issued FSP FAS 157-2, Effective Date of FASB Statement No. 157, or FSP FAS 157-2. FSP FAS 157-2, which was effective upon issuance, delays the effective date of SFAS No. 157 for nonfinancial assets and nonfinancial liabilities, except for items that are recognized or disclosed at fair value at least once a year, to fiscal years beginning after November 15, 2008. On January 1, 2009, we will adopt SFAS No. 157 for nonfinancial assets and liabilities that are not measured at fair value on a recurring basis. Our nonfinancial assets and liabilities will be limited to the initial recognition of asset retirement obligations. FSP FAS 157-2 also covers interim periods within the fiscal years for items within its scope. The delay is intended to allow the FASB and its constituents the time to consider the various implementation issues associated with SFAS No. 157. We adopted SFAS No. 157 as of January 1, 2008 with respect to our derivative instruments which are measured at fair value within our financial statements. See Note 7 for disclosures pertaining to the provisions of SFAS No. 157 with regard to our fair value measurements.

ITEM 8.                      FINANCIAL STATEMENTS

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Partners of

Atlas America Public #15-2005(A) L.P.

We have audited the accompanying balance sheets of Atlas America Public #15-2005(A) L.P. (a Delaware Limited Partnership) as of December 31, 2008 and 2007, and the related statements of operations, comprehensive loss, changes in partners’ capital, and cash flows for the years then ended. 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Partnership is not required to have, nor were we engaged to perform an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Partnership’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, 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 financial statements referred to above present fairly, in all material respects, the financial position of Atlas America Public #15-2005(A) L.P. as of December 31, 2008 and 2007, and the results of its operations and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2008

NOTE 1 – DESCRIPTION OF BUSINESS

Atlas America Public #15-2005 (A) L.P. (the “Partnership”) is a Delaware Limited Partnership, which includes Atlas Resources, LLC of Pittsburgh, Pennsylvania, as Managing General Partner (“MGP”) and Operator, and 1,631 Limited Partners. The Partnership was formed on July 25, 2005 to drill and operate gas wells located primarily in western Pennsylvania, and Tennessee.

In March 2006, Atlas Resources, Inc., the Partnership's MGP was merged into a newly-formed limited liability company, Atlas Resources, LLC, which became an indirect subsidiary of Atlas America, Inc.  Atlas Resources, LLC now serves as the Partnership's MGP.  In December 2006, Atlas America, Inc. contributed substantially all of its natural gas and oil exploration and production assets to Atlas Energy Resources, LLC.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A summary of significant accounting policies applied in the preparation of the accompanying financial statements follows:

Basis of Accounting

The financial statements are prepared in accordance with accounting principles generally accepted in the United States of America.

Use of Estimates

Preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues, costs and expenses during the reporting period.  Actual results could differ from these estimates.

Reclassifications

Certain reclassifications have been made to the 2007 presentation to conform to the 2008 presentation.

Account Receivable and Allowance for Possible Losses

In evaluating the need for an allowance for possible losses, the MGP performs ongoing credit evaluations of its customers and adjusts credit limits based upon payment history and the customer’s current creditworthiness, as determined by Atlas’s review of its customers' credit information.  Credit is extended on an unsecured basis to many of its energy customers. At December 31, 2008 and 2007, the Partnership’s MGP’s credit evaluation indicated that the Partnership had no need for an allowance for possible losses.

Revenue Recognition

Revenues from sales of natural gas and oil are recognized by the Partnership when the gas and oil have been delivered to the purchaser.  The Partnership’s natural gas and oil is sold under various contracts entered into by its MGP.  Virtually all of our MGP’s contract pricing provisions are tied to a market index, with certain adjustments based on, among other factors, whether a well delivers to a gathering or transmission line, quality of natural gas and prevailing supply and demand conditions, so that the price the Partnership receives from the sale of its natural gas fluctuates to remain competitive with natural gas supplies generally available in the market.

NOTES TO FINANCIAL STATEMENTS – (Continued)

DECEMBER 31, 2008

NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Because there are timing differences between the delivery of the Partnership’s natural gas and oil and the receipt of a delivery statement, the Partnership has unbilled revenues.  These revenues are accrued based upon volumetric data from the Partnership’s records and estimates of the related transportation and compression fees which are, in turn, based upon applicable product prices.  The Partnership had unbilled trade receivables of $1,074,300 at December 31, 2008 and $1,559,200 at December 31, 2007, which are included in Accounts receivable-affiliate on the Partnership's Balance Sheets.

Fair Value of Financial Instruments

For cash, receivables and payables, the carrying amounts approximate fair values because of the short maturities of these instruments.

For derivatives, the carrying value approximates fair value because they have been marked to market.

Supplemental Cash Flow Information

The Partnership considers temporary investments with a maturity at the date of acquisition of 90 days or less to be cash equivalents.  No cash was paid by the Partnership for interest or income taxes for the years ended December 31, 2008 and 2007.

Concentration of Credit Risk

Financial instruments, which potentially subject the Partnership to concentrations of credit risk, consist principally of periodic temporary investments of cash and cash equivalents.  The Partnership places its temporary cash investments in deposits with high-quality financial institutions.  At December 31, 2008, the Partnership had $502,500 in deposits at one bank of which $252,500 was over the insurance limit of the Federal Deposit Insurance Corporation and at December 31, 2007, the Partnership had $802,800 in deposits at one bank of which $702,800 was over the insurance limit of the Federal Deposit Insurance Corporation.  No losses have been experienced on such investments.

Comprehensive Loss

Comprehensive loss includes net loss and all other changes in equity of a business during a period from transactions and other events and circumstances from non-owner sources. These changes, other than net loss, are referred to as "other comprehensive income (loss)" and, for the Partnership, include changes in the fair value of hedging contracts related to commodity derivatives.

Oil and Gas Properties

Oil and gas properties are stated at cost.  Depletion is based on cost less estimated salvage value primarily using the unit-of-production method over the assets’ estimated useful lives. Maintenance and repairs are expensed as incurred. Major renewals and improvements that extend the useful lives of property are capitalized.

NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Oil and gas properties consist of the following at the dates indicated:	December 31,
	2008			2007
Natural gas and oil properties:
Proved properties:
Leasehold interests	$	1,526,600		$	1,503,700
Wells and related equipment		64,310,600			63,334,400
		65,837,200			64,838,100
Accumulated depletion		(47,345,200	)		(15,466,000	)
	$	18,492,000		$	49,372,100

The Partnership uses the successful efforts method of accounting for oil and gas producing activities. Costs to acquire mineral interests in oil and gas properties and to drill and equip wells are capitalized. Oil is converted to gas equivalent basis (“mcfe”) at the rate of one barrel equals 6 mcf.

The Partnership’s long-lived assets are reviewed for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Long-lived assets are reviewed for potential impairments at the lowest levels for which there are identifiable cash flows.  The review is done by determining if the historical cost of proved properties less the applicable accumulated depreciation, depletion and amortization and salvage value is less than the estimated expected undiscounted future cash flows. The expected future cash flows are estimated based on the Partnership’s plans to continue to produce and develop proved reserves. The estimated future level of production is based on assumptions surrounding future levels of prices and costs, field decline rates, market demand and supply, and the economic and regulatory climates. If the carrying value exceeds such undiscounted cash flows, an impairment loss is recognized for the difference between the estimated fair market value and the carrying value of the assets. The fair market value is determined as the present value of future net revenues from the production of proved reserves discounted using an annual discount rate of 12% in 2008 and 9% in 2007 and the 12 month NYMEX forward looking strip price for natural gas. During 2008 and 2006, the Partnership recognized impairment loss of $24,849,500 and $3,445,300, respectively, net of an offsetting gain in other comprehensive income of $2,520,200 and $330,800, respectively. There was no impairment charge for the year ended December 31, 2007.

Upon the sale or retirement of a complete or partial unit of a proved property, the cost is eliminated from the property accounts, and the resultant gain or loss is reclassified to accumulated depletion. Upon the sale of an entire interest where the property had been assessed for impairment, a gain or loss is recognized in the Statements of Operations.

Asset Retirement Obligation

The fair values of asset retirement obligations are recognized in the period they are incurred if a reasonable estimate of fair value can be made. Asset retirement obligations primarily relate to the abandonment of oil and gas producing properties and include costs to dismantle and relocate or dispose of production equipment, gathering systems, wells and related structures. Estimates are based on historical experience in plugging and abandoning wells, estimated remaining lives of those wells based on reserve estimates, external estimates as to the cost to plug and abandon the wells in the future and federal and state regulatory requirements. The Partnership does not provide for a market risk premium associated with asset retirement obligations because a reliable estimate cannot be determined, see Note 8.

NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

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 No. 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. Atlas Energy maintains insurance that may cover in whole or in part certain environmental expenditures. For the years ended December 31, 2008 and 2007, the Partnership had no environmental matters requiring specific disclosure or the recording of a liability.

Major Customers

The partnership’s natural gas is sold under contract to various purchasers.  For the year ended December 31, 2008, sales to UGI Energy Services, Inc., Conoco Phillips Company, Exelon Energy Company, Colonial Energy, Inc. and Equitable Gas accounted for 17%, 16%, 14%, 14% and 13%, respectively, of total revenues. For the year ended December 31, 2007, sales to UGI Energy Services, Inc., Exelon Energy Company, Colonial Energy, Inc. and Interstate Gas Supply, Inc. accounted for 31%, 15%, 14% and 12%, respectively, of total revenues. No other customers accounted for 10% or more of total revenues for the years ended December 31, 2008 and 2007.

Income Taxes

The Partnership is not treated as a taxable entity for federal income tax purposes. Any item of income, gain, loss, deduction or credit flows through to the partners as though each partner had incurred such item directly. As a result, each partner must take into account his pro rata share of all items of partnership income and deductions in computing his federal income tax liability.

Recently Issued Financial Accounting Standards

In May 2008, the Financial Accounting Standards Board, ("FASB") issued Statement of Financial Accounting Standards No. 162, The Hierarchy of Generally Accepted Accounting Policies ("SFAS 162"), which reorganizes the GAAP hierarchy. The purpose of the new standard is to improve financial reporting by providing a consistent framework for determining what accounting principles should be used when preparing the U.S. GAAP financial statements. The standard is effective 60 days after the SEC's approval of the PCAOB's amendments to AU Section 411. The adoption of SFAS 162 will not have an impact on the Partnership's financial position or results of operations.

NOTES TO FINANCIAL STATEMENTS – (Continued)

DECEMBER 31, 2008

NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities, or SFAS 161, an amendment of FASB Statement No. 133, Accounting for Derivative Instruments and Hedging Activities, (“SFAS 133”). SFAS 161 requires entities to provide qualitative disclosures about the objectives and strategies for using derivatives, quantitative data about the fair value of and gains and losses on derivative contracts, and details of credit-risk-related contingent features in their hedged positions. The standard is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged, but not required. SFAS 161 also requires entities to disclose more information about the location and amounts of derivative instruments in financial statements; how derivatives and related hedges are accounted for under SFAS 133 and how the hedges affect the entity’s financial position, financial performance, and cash flows. The Partnership will apply the requirements of SFAS No. 161 on its adoption on January 1, 2009 and does not expect it to have an impact on its financial position or results of operations.

In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159, The Fair Value Option for Financial Assets and Financial Liabilities, (“SFAS No. 159”). SFAS No. 159 permits entities to choose to measure eligible financial instruments and certain other items at fair value. The objective is to improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. By electing the fair value option in conjunction with a derivative, an entity can achieve an accounting result similar to a fair value hedge without having to comply with complex hedge accounting rules. The statement was effective for the Partnership as of January 1, 2008. The Partnership adopted SFAS No. 159 at January 1, 2008, and has elected not to apply the fair value option to any of its financial instruments not already carried at fair value in accordance with other accounting standards, and therefore the adoption of SFAS No. 159 did not impact the Partnership’s financial statements for the year ended December 31, 2008.

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157, Fair Value Measurement, (”SFAS No. 157”). SFAS No. 157 addresses the need for increased consistency in fair value measurements, defining fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. It also establishes a framework for measuring fair value and expands disclosure requirements. In February 2008, the FASB issued FSP FAS 157-2, Effective Date of FASB Statement No. 157, (“FSP FAS 157-2”). FSP FAS 157-2, which was effective upon issuance, delays the effective date of SFAS No. 157 for nonfinancial assets and nonfinancial liabilities, except for items that are recognized or disclosed at fair value at least once a year, to fiscal years beginning after November 15, 2008. On January 1, 2009, the Partnership will adopt SFAS No. 157 for nonfinancial assets and liabilities that are not measured at fair value on a recurring basis. For the Partnership, the nonfinancial assets and liabilities will be limited to the initial recognition of asset retirement obligations. FSP FAS 157-2 also covers interim periods within the fiscal years for items within its scope. The delay is intended to allow the FASB and its constituents the time to consider the various implementation issues associated with SFAS No. 157. The Partnership adopted SFAS No. 157 as of January 1, 2008 with respect to its derivative instruments which are measured at fair value within its financial statements. See Note 7 for disclosures pertaining to the provisions of SFAS No. 157 with regard to the Partnership’s fair value measurements.

NOTE 4 – CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS (Continued)

·   Assets contributed from the MGP, which are disclosed in the Partnership's Statement of Cash Flows as a non-cash activity for the year ended December 31, 2008, were $841,700. Assets returned to the MGP, which are disclosed on the Partnership's Statement of Cash Flows as a non-cash activity for the year ended December 31, 2007, were $383,300.

The MGP and its affiliates perform all administrative and management functions for the Partnership including billing revenues and paying expenses. The line-item “Accounts receivable-affiliate” on the Partnership’s Balance Sheets represents the net production revenues due from the MGP.

NOTE 5 - COMMITMENTS

Subject to certain conditions, investor partners may present their interests beginning in 2010 for purchase by the MGP. The purchase price is calculated by the MGP in accordance with the terms of the partnership agreement.  The MGP is not obligated to purchase more than 5% of the units in any calendar year. In the event that the MGP is unable to obtain the necessary funds, the MGP may suspend its purchase obligation.

Beginning one year after each of the Partnership’s wells has been placed into production the MGP, as operator, may retain $200 per month per well to cover the estimated future plugging and abandonment costs.  As of December 31, 2008, the MGP has not withheld any such funds.

NOTE 6 - SUBORDINATION BY MANAGING GENERAL PARTNER

Under the terms of the partnership agreement, the MGP may be required to subordinate up to 50% of its share of production revenues of the Partnership to provide a distribution to the limited partners equal to at least 10% of their agreed subscriptions.  Subordination is determined on a cumulative basis, in each of the first five years of Partnership operations, commencing with the first distribution of revenues to the investor partners (August 2006).  Since inception of the Partnership, the MGP has not been required to subordinate any of its revenues to its limited partners.

NOTE 7 – DERIVATIVE INSTRUMENTS

Atlas Energy on behalf of the Partnership from time to time enters into natural gas future option contracts and collar contracts to hedge exposure to changes in natural gas prices. At any point in time, such contracts may include regulated New York Mercantile Exchange ("NYMEX") futures, options contracts, and non-regulated over-the-counter futures contracts with qualified counterparties. NYMEX contracts are generally settled with offsetting positions, but may be settled by the delivery of natural gas. Oil contracts are based on a West Texas Intermediate ("WTI") index. These contracts have qualified and been designated as cash flow hedges and recorded at their fair values.

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.

NOTE 7 – DERIVATIVE INSTRUMENTS (Continued)

At December 31, 2008, Atlas Energy had allocated open natural gas futures contracts to the Partnership related to natural gas sales covering 1,810,300 dekatherms (“Dth”) of gas, maturing through December 31, 2013 at an average settlement price of $8.22 per Dth. In addition, Atlas Energy had allocated oil futures contracts to the Partnership related to oil sales covering 2,400 barrels (“Bbls”) of oil, maturing through April 30, 2013 at an average settlement price of $98.31 per Bbl. At December 31, 2008, the Partnership reflected a net hedge asset on our Balance Sheets of $2,520,200. Due to the impairment of the Partnership’s oil and gas properties at December 31, 2008 and 2006, a net offsetting unrealized gain of $2,520,200 and $330,800, respectively, was reclassified into earnings from accumulated other comprehensive income, respectively. At December 31, 2008, a reclassification remains in accumulated other comprehensive loss for 2006 of $57,700.  Of the $57,700 net loss in accumulated other comprehensive loss at December 31, 2008, if the fair values of the instruments remain at current market values, the Partnership will reclassify $53,600 net losses to our Statements of Operations over the next twelve month period as these contracts expire, and $4,100 of net losses in later periods. Actual amounts that will be reclassified will vary as a result of future price changes. The Partnership realized losses of $306,600 and gains of $1,842,100 for the years ended December 31, 2008 and 2007, respectively; in our oil and gas revenues within the Statements of Operations related to the settlement of qualifying hedge instruments. Ineffective hedge gains or losses are recorded within the Statements of Operations while the hedge contract is open and may increase or decrease until settlement of the contract. The Partnership recognized no gains or losses during the years ended December 31, 2008 and 2007 for hedge ineffectiveness or as a result of the discontinuance of cash flow hedges.

As of December 31, 2008, Atlas Energy had allocated to the Partnership the following natural gas and oil volumes hedged:

Natural Gas Fixed Price Swaps

Production			Average
Period Ending	Volumes		Fixed Price		Fair Value

Fair Value of Financial Instruments

The Partnership adopted the provisions of SFAS 157 at January 1, 2008. SFAS 157 establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. SFAS 157’s hierarchy defines three levels of inputs that may be used to measure fair value:

Level 1– Quoted prices in active markets for identical assets and liabilities that the reporting entity has the ability to access at the measurement date.

NOTE 7 – DERIVATIVE INSTRUMENTS (Continued)

Level 2– Inputs other than quoted prices included within Level 1 that are observable for the asset and liability or can be corroborated with observable market data for substantially the entire contractual term of the asset or liability.

Level 3– Unobservable inputs that reflect the entity's own assumptions about the assumptions that market participants would use in the pricing of the asset or liability and are consequently not based on market activity, but rather through particular valuation techniques.

The Partnership uses the fair value methodology outlined in SFAS 157 to value the assets and liabilities for its outstanding derivative contracts. All of the Partnership’s derivatives contracts are defined as Level 2. The Partnership's natural gas and crude oil derivative contracts are valued based on prices quoted on the NYMEX or WTI and adjusted by the respective counterparty using various assumptions including quoted forward prices, time value, volatility factors, and contractual prices for the underlying instruments. In accordance with SFAS 157, the following table represents the Partnership's fair value hierarchy for its financial instruments at December 31, 2008.

NOTE 9 - NATURAL GAS AND OIL PRODUCING ACTIVITIES (UNAUDITED) (Continued)

The supplementary information summarized below presents the results of natural gas and oil activities in accordance with Statements of Financial Accounting Standards No. 69, Disclosures about Oil and Gas Producing Activities, (“SFAS No. 69”).  Annually, reserve value information is provided to the investor partners pursuant to the partnership agreement.  The partnership agreement provides a presentment feature whereby the MGP will buy partnership units, subject to annual limitations, based upon a valuation formula price in the partnership agreement. Therefore, certain information required under SFAS No. 69 is not presented.

No consideration has been given in the following information to the income tax effect of the activities, as the Partnership is not treated as a taxable entity for income tax purposes.

(1)   Capitalized Costs Related to Oil and Gas Producing Activities

The following table presents the capitalized costs related to natural gas and oil producing activities at the periods indicated:

	At December 31,
	2008			2007
Mineral interest in proved properties:	$	1,526,600		$	1,503,700
Wells and related equipment		64,310,600			63,334,400
Accumulated depletion		(47,345,200	)		(15,466,000	)
Net capitalized cost	$	18,492,000		$	49,372,100

(2)   Oil and Gas Reserve Information

The information presented below represents estimates of proved developed natural gas and oil reserves. All reserves are proved developed reserves and are located in the Appalachian Basin area. The estimates of the Partnership’s proved developed gas and oil reserves are based upon evaluations made by management and verified by Wright & Company, Inc., an independent petroleum-engineering firm, as of December 31, 2008 and 2007. All reserves are located within the United States of America.  Reserves are estimated in accordance with guidelines established by the Securities and Exchange Commission and the Financial Accounting Standards Board which require that reserve estimates be prepared under existing economic and operating conditions with no provision for price and cost escalation except by contractual arrangements. Proved developed reserves are estimated quantities of crude oil and natural gas which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions, i.e. prices and costs as of the date the estimate is made. Prices include consideration of changes in existing prices provided only by contractual arrangements, but not on escalations based upon future conditions.

Proved developed reserves are those which are expected to be recovered through existing wells with existing equipment and operating methods. Additional oil and gas expected to be obtained through the application of fluid injection or other improved recovery techniques for supplementing the natural forces and mechanisms of primary recovery should be included as “proved developed reserves” only after testing by a pilot project or after the operation of an installed program has confirmed through production response that increased recovery will be achieved.

NOTE 9- NATURAL GAS AND OIL PRODUCING ACTIVITIES (UNAUDITED) (Continued)

There are numerous uncertainties inherent in estimating quantities of proved developed reserves and in projecting future net revenues and the timing of development expenditures. The reserve data presented represents estimates only and should not be construed as being exact.  In addition, the standardized measures of discounted future net cash flows may not represent the fair market value of the Partnership’s gas reserves or the present value of future cash flows of equivalent reserves, due to anticipated future changes in and gas prices and in production and development costs and other factors for which effects have not been provided.

ITEM 9A.  CONTROLS AND PROCEDURES

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Securities Exchange Act of 1934 reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chairman of the Board of Directors, Chief Executive Officer and President, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, our management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

36

Under the supervision of our Chairman of the Board of Directors, Chief Executive Officer and President, we have carried out an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based upon that evaluation, our Chairman of the Board of Directors, Chief Executive Officer and President, concluded that, as of December 31, 2008, our disclosure controls and procedures were effective at the reasonable assurance level.

Management’s Report on Internal Control over Financial Reporting

Our management 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 Chairman of the Board of Directors, Chief Executive Officer and President, 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 cannot 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.

Based on our evaluation under the COSO framework, management concluded that our internal control over financial reporting as of December 31, 2008 was effective.

This annual report does not include an attestation report by Grant Thornton regarding internal control over financial reporting. Management's report was not subject to attestation by Grant Thornton pursuant to temporary rules of the Securities and Exchange Commission that permit the Company to provide only management's report in this annual report.
