ITEM 1. BUSINESS.

The following discussion contains forward-looking statements regarding events and financial trends that may affect our future operating results and financial position. These statements are subject to risks and uncertainties that could cause our actual results and financial position to differ materially from the results anticipated in those statements. These risks include risks associated with drilling and operating our wells, marketing natural gas and oil production from the wells, and fluctuations in market prices for the natural gas and oil produced from the wells. For a more complete discussion of the risks and uncertainties to which we are subject, See “Risk Factors” in Item 1A beginning on page 12. The terms “we,” “our,” and “us” used in this Form 10 are used as references to Atlas Resources Series 28-2010 L.P.

General

We were formed as a Delaware limited partnership on March 12, 2010, with Atlas Resources, LLC, a Pennsylvania limited liability company, as our managing general partner. We are a drilling program that acquires drilling rights under oil and gas leases for the drilling and production of natural gas wells, although we may have some oil production. The primary areas where our wells are situated are the Marcellus Shale geological formation in Pennsylvania, the New Albany Shale in Indiana, the Niobrara reservoir in Colorado and the Antrim Shale in Michigan. See Item 3 — “Properties” beginning on page 34.

We are filing this General Form for Registration of Securities on Form 10 to register our Units pursuant to Section 12(g) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We are subject to the registration requirements of Section 12(g) because at the end of our first fiscal year on December 31, 2010, the aggregate value of our assets exceeded the applicable threshold of $10 million and our Units of record were held by more than 500 persons. Because of our obligation to register our Units with the Securities and Exchange Commission (the “SEC”) under the Exchange Act, we will be subject to the requirements of the Exchange Act rules and we intend to file:

• quarterly reports on Form 10-Q;

• annual reports on Form 10-K;

• current reports on Form 8-K; and

otherwise comply with the disclosure obligations of the Exchange Act applicable to issuers filing registration statements pursuant to Section 12(g) of the Exchange Act.

Employees. We have no employees. Instead, we rely on our managing general partner for management services, and our managing general partner relies on its indirect parent company, Atlas Energy, L.P. (“Atlas Energy”), and its affiliates for management and administrative services and financing for capital expenditures. See Item 5 “Directors and Executive Officers,” beginning on page 38, and the organizational chart on page 44.

Our Offering. Our offering was conducted in reliance on the exemption from registration provided by Rule 506 under Regulation D and Section 4(2) of the Securities Act. All of our participants were reasonably believed by our managing general partner to be accredited investors at the time of sale. We broke escrow and had our first closing on May 14, 2010. When we had our final closing on September 20, 2010, we had 2,273 investors who purchased our Units (our “participants”). “Units” means our limited partner Units, our converted limited partner Units and our investor general partner Units that will automatically be converted by our managing general partner into the converted limited partner Units once all of our wells are drilled and completed. As of September 20, 2010, we had 7,021 investor general partner Units outstanding, which will automatically be converted by our managing general partner to limited partner Units after all of our wells are drilled and completed, and 479 of limited partner Units outstanding. In accordance with the terms of our offering, 7,312 Units were sold at $20,000 per Unit, and 188 Units were sold at discounted prices to selling agents and their registered representatives and principals and clients of registered investment advisors, and investors who bought Units through the officers and directors of our managing general partner. No Units were sold to our managing general partner, and its officers, directors and affiliates.

Our participants contributed a total of $149,724,600 in subscription proceeds to us, which we paid to our managing general partner serving as our operator and general drilling contractor under our drilling and operating agreement. We used all of our subscription proceeds to drill and complete wells located primarily in western Pennsylvania, central Indiana, northern Colorado and northern Michigan. Under our partnership agreement, all of the subscription proceeds of our participants were used to pay the intangible drilling costs of our wells and a portion of the tangible costs. “Intangible drilling costs” generally means those costs of drilling and completing a well that are currently deductible, as compared with lease costs, which must be recovered through the depletion allowance, and equipment costs, which must be recovered through depreciation deductions. “Tangible costs” generally means the equipment costs of drilling and completing a well that are not currently deductible as intangible drilling costs and are not lease costs. Our managing general partner was required to contribute all of the leases on which our wells are situated, pay and/or contribute services towards our organization and offering costs up to an amount equal to 15% of our participants’ subscription proceeds and pay all of our equipment costs to drill and complete our wells that were not paid with our participants’ subscription proceeds. As of December 31, 2010, the aggregate amount of these contributions by our managing general partner was $33,909,100. A tabular presentation of the respective capital contributions to us of the participants and our managing general partner as of December 31, 2010 is set forth below.

2

Capital Contributions to Us As of 12/31/10 (1)

Participants	$	149,724,600
Managing General Partner	$	33,909,100	(2)

(1)	Our cash distributions are allocated between our managing general partner and our participants in the same percentages as their respective capital contributions bear to our total capital contributions, except that our managing general partner receives an additional 10% of our distributions regardless of the amount of its capital contribution.
(2)	Our managing general partner’s capital contributions to us increased from $33,909,100 as of December 31, 2010 to $37,891,600 as of March 31, 2011 (unaudited) and are expected to increase further as our drilling activities are completed. Currently, our managing general partner anticipates that its total capital contributions to us eventually will be approximately $46,632,000.

Investment Objectives. Our investment objectives are to:

• Provide monthly cash distributions to our participants from the wells drilled with our subscription proceeds until the wells are depleted, with a minimum annual return of capital of 12% during the first 12-month subordination period, 10% during the next three 12-month subordination periods, and 8% during the fifth 12-month subordination period based on $20,000 per Unit regardless of the actual subscription price paid, beginning when natural gas or oil is being sold from at least 75% of our wells. These distributions during the 60-month aggregate subordination period are not guaranteed, but are subject to our managing general partner’s subordination obligation as described in Item 11 “Description of Registrant’s Securities to be Registered — Distributions and Subordination,” beginning on page 61.

Under current conditions, and based in part on the drilling results of the 51.58 net wells which we drilled in 2010 (approximately 43% of our estimated total of 118.69 net wells to be drilled), we believe that our participants will receive the minimum aggregate distributions described above each year during this 60-month aggregate subordination period. See Item 3 “Properties” beginning on page 34, and the “Notes to Financial Statements — Note 10” in Item 13 “Financial Statements and Supplementary Data” beginning on page 89. However, we do not yet know the drilling results of all of the 67.11 net wells which we prepaid in 2010 (approximately 57% of our estimated total of 118.69 net wells to be drilled), since we were still in the process of drilling 35.11 of our net wells on March 31, 2011. Therefore, a participant should not rely on the results of the wells we drilled in 2010 as being indicative of the results of the wells drilled in 2011. Also, current conditions, such as prices for natural gas and our costs for operating our wells, will change during the 60-month aggregate subordination period. See Item 1A “Risk Factors” beginning on page 12.

3

• Obtain federal income tax deductions in 2010 from intangible drilling costs in an amount guaranteed to equal not less than 85% of each participant’s subscription price for his or her Units. Not less than 85% of our subscription proceeds must be used to pay the intangible drilling costs we incur to drill and complete our wells. These deductions for intangible drilling costs may be used to offset a portion of the participant’s taxable income subject to any objections by the IRS, each participant’s individual tax circumstances, and the passive activity rules if the participant invested in us as a limited partner. For example, if a participant paid $20,000 for a Unit the investment would produce a 2010 tax deduction of not less than $17,000 per unit, 85%, against:

• ordinary income, or capital gain in some situations, if the participant invested as an investor general partner; and

• passive income if the participant invested as a limited partner.

In the first quarter of 2011, our IRS Schedule K-1’s to our participants reported a deduction for intangible drilling costs in 2010 in an amount equal to 85% of the subscription price paid by each participant. However, we do not guarantee the IRS’ treatment of our participants’ deductions for intangible drilling costs. If the IRS were to decrease the amount of the deduction, or defer part of the deduction to 2011 for wells we prepaid in 2010, for example, our participants would not be entitled to any reimbursement from us for any increase in taxes owed, penalties or interest or any other lost tax benefits.

• Offset a portion of any gross production income generated by us with tax deductions from percentage depletion.

• Provide each of our participants with tax deductions, in an aggregate amount guaranteed to equal up to the remaining 15% of the participant’s initial investment in us that was used to pay equipment costs of our wells, instead of intangible drilling costs, through annual depreciation deductions over a seven-year cost recovery period, subject to:

• a 50% write-off in 2010 for the costs of qualified equipment acquired before September 8, 2010 and used in wells placed in service for the production of natural gas production in 2010; or

• a 100% write-off in 2010 for the costs of qualified equipment acquired after September 8, 2010 and used in wells placed in service for the production of natural gas in either 2010 or 2011.

Under Section 5.01(a) of our partnership agreement, all of our subscription proceeds that are not used to pay intangible drilling costs must be used to pay the equipment costs we incur to drill and complete our wells. For example, if 86% of our subscription proceeds is used to pay intangible drilling costs, then we guarantee that the remaining 14% of our subscription proceeds will be used to pay equipment costs.

4

The tax benefits of these depreciation deductions to our participants are subject to any objections by the IRS, each participant’s individual tax circumstances, and the passive activity rules if the participant invested as a limited partner or is a converted limited partner. Also, we do not guarantee the IRS’ treatment of our participants’ depreciation deductions for our equipment costs. If the IRS were to decrease the amount of the deductions, for example, our participants would not be entitled to any reimbursement from us for any increase in taxes owed, penalties or interest or any other lost tax benefits.

Oil and Natural Gas Properties. As of December 31, 2010, we had drilled 51.58 net development wells, and as of March 31, 2011 we had drilled an additional 32.00 net development wells and had begun drilling approximately 35.11 more net development wells. Because all of our wells have not yet been drilled and completed, our investor general partner Units have not yet been converted to limited partner Units. We will not drill any wells except the wells funded with our subscription proceeds and our managing general partner’s capital contributions to us as described above. For further information concerning our natural gas and oil properties, including the status of our drilling activities, our leasing practices and our reserve and acreage information, see Item 3 “Properties” beginning on page 34. We believe that our ongoing operating and maintenance costs for our productive wells will be paid through revenues we receive from the sale of our natural gas and oil production as discussed in Item 2 “Financial Information” beginning on page 27. Thus, the subscription proceeds from the offering of our Units in 2010 and our ongoing natural gas and oil production revenues from our wells will satisfy all of our cash requirements and we will not seek to raise additional funds from either our participants or new investors.

We pay our managing general partner a monthly well supervision fee of $975 per well per month in the Marcellus Shale primary area in western Pennsylvania, $1,500 per well per month in the New Albany Shale primary area in central Indiana, and $600 per well per month in the Antrim Shale primary area in northern Michigan, for serving as the operator of our wells. 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, rebuilding of access roads, water hauling, or certain other goods or services provided by our managing general partner’s affiliates at competitive rates in the area or by third-parties. In this regard, our managing general partner will determine competitive industry rates for equipment, supplies and other services by conducting a survey of the interest and/or fees charged by unaffiliated third-parties engaged in similar businesses in the same geographic areas. If possible, our managing general partner will contact at least two unaffiliated third-parties; however, our managing general partner will have sole discretion in determining the amount to be charged us, subject to the foregoing.

5

Production. All of our wells are expected to produce natural gas, and some of our wells are currently producing natural gas and to a far lesser extent oil, which are our only products. We do not plan to sell any of our wells and intend to continue to produce them until they are depleted, at which time they will be plugged and abandoned. See Item 3 “Properties” beginning on page 34 for information concerning:

• our natural gas and oil production quantities;

• average sales prices; and

• average production costs.

Sale of Natural Gas and Oil Production. Our managing general partner is responsible for selling our natural gas and oil production. In the geographic areas where our wells are situated, our managing general partner is a party to natural gas contracts with various natural gas purchasers, each of which is paying a different price for our natural gas. Our managing general partner is also responsible for gathering and transporting the natural gas produced by us to interstate pipeline systems, local distribution companies, and/or end-users in the area (the “gathering services”), and we pay our managing general partner a competitive gathering fee for this service. In providing the gathering services our managing general partner may use gathering systems owned by its affiliates or independent third-parties.

We will pay a gathering fee directly to our managing general partner at competitive rates for the gathering services. The gathering fee paid by us to our managing general partner may be increased from time-to-time by our managing general partner, in its sole discretion, but may not be increased beyond competitive rates as determined by our managing general partner. Currently, our managing general partner has determined that the competitive rates in our primary areas are as follows:

• in the Marcellus Shale primary area, an amount equal to 16% of the gross sales price received by us for our natural gas, and for this purpose gross sales price means the price that is actually received, adjusted to take into account proceeds received or payments made pursuant to hedging arrangements;

• in the New Albany Shale (Indiana) primary area, a gathering fee of $0.005 (1/2 of one cent) per mcf per mile the natural gas is transported, plus a processing fee of $1.00 per mcf if the natural gas is processed through a processing plant in Indiana in which an affiliate of our managing general partner owns an interest; and

• in the Antrim Shale primary area in Michigan, an average gathering fee of approximately $.30 per mcf transported.

6

The payment of a competitive fee to our managing general partner for its gathering services is subject to the following conditions:

• If a third-party gathering system is used by us, then our managing general partner’s gathering fee with respect to our natural gas will be the actual transportation and compression fees charged by the third-party gathering system and our managing general partner will pay all of the gathering fee it receives from us to the third-party gathering the natural gas.

• If both a third-party gathering system and a gas gathering system owned by an affiliate of our managing general partner are used by us, then our managing general partner will receive an amount equal to a competitive fee as described above for the natural gas transported by the segment provided by the gathering system owned by an affiliate of our managing general partner, plus the amount charged by the third-party gathering system for the natural gas transported by the segment provided by the third-party.

Our managing general partner will determine competitive industry rates for its gathering services by conducting a survey of gathering fees charged by unaffiliated third-parties in the same geographic areas. If possible, our managing general partner will contact at least two unaffiliated third-parties; however, our managing general partner will have sole discretion in determining the amount to be charged us, subject to the foregoing.

Our managing general partner considers a drilling area to be a primary drilling area if 10% or more of our subscription proceeds are used to drill wells in the area. In this regard, our managing general partner anticipates that:

• The natural gas produced from the Marcellus Shale primary area in Pennsylvania will be sold primarily to UGI Energy Services, Colonial Energy, Inc., South Jersey Resources Group, ConocoPhillips Company, Dominion Field Services, Inc., EQT Energy LLC, Equitable Gas Company, Sequent Energy Management, L.P., and NJR Energy Services pursuant to various contracts.

• The natural gas produced from the New Albany Shale primary area in Indiana will be sold primarily to Atmos Energy pursuant to contracts which end March 31, 2014.

• The natural gas produced from the Antrim Shale primary area in Michigan will be sold primarily to DTE Energy Company, BP Canada, Conoco Phillips, Sequent Energy, Nexen, and Total Gas & Power pursuant to various contracts or on the spot market.

All of the natural gas contracts described above are between the natural gas purchaser and our managing general partner or its affiliates. Either our managing general partner or its affiliates will receive the sales proceeds from the natural gas purchasers and then distribute the sales proceeds to us based on the volume of natural gas produced by us. Until the sales proceeds are distributed to us, they will be subject to the claims of our managing general partner’s or its affiliates’ creditors.

7

The pricing and delivery arrangements with the vast majority of the natural gas purchasers described above are tied to the settlement of the New York Mercantile Exchange Commission (“NYMEX”) monthly futures contracts price, which is reported daily in the Wall Street Journal, with an additional premium, which is referred to as the basis, paid for natural gas production in the Appalachian Basin because of the relatively close location of the natural gas in relation to the natural gas market. These arrangements do not include our natural gas production from the New Albany Shale primary area in Indiana or the Antrim Shale primary area in Michigan since these areas are not situated in the Appalachian Basin.

Pricing for natural gas and oil production has been volatile and unpredictable for many years. Currently, none of our natural gas production is subject to hedging arrangements. Instead, our production is sold at contract prices in the month produced or at spot market prices. The prices under most of our gas sales contracts are negotiated on an annual basis and are index-based. However, to limit our exposure if natural gas prices fall, we have used hedges in the past, and expect to do so again in the future, to lock in a range of pricing for a significant portion of our production during the periods covered by the hedges. In this regard, in conjunction with the “Asset Acquisition” and the “Chevron Merger” described in Item 5 “Directors and Executive Officers — Managing General Partner,” beginning on page 38, all of the previous derivative contracts related to the natural gas and oil production of the partnerships sponsored by our managing general partner, including us, were monetized and we and the other partnerships will share in the total available hedge gains based on each partnership’s actual production volumes during the period of the original derivative contracts, some which would have extended into 2014.

With respect to future hedging arrangements, our managing general partner and its affiliates may enter into financial hedges through contracts such as NYMEX futures and options contracts and over-the-counter futures contracts through banking counterparties on behalf of us and the other partnerships sponsored by our managing general partner, including future partnerships. They may also use physical hedges through their natural gas purchasers as discussed below. These futures contracts are commitments to purchase or sell natural gas at future dates and generally have covered one-month periods for up to 60 months in the future. To assure that the financial instruments will be used solely for hedging price risks and not for speculative purposes, our managing general partner has established a risk management committee to assure that all financial trading is done in compliance with our managing general partner’s hedging policies and procedures. Our managing general partner does not intend to contract for positions that it cannot offset with actual production. Any physical hedges require firm delivery of natural gas and, therefore, are considered normal sales of natural gas, rather than hedges, for accounting purposes. Additionally, we may enter into our own agreements and financial instruments relating to hedging our natural gas and oil and the pledging of up to 100% of our assets and reserves in connection therewith.

8

The percentages of our natural gas that may hedged in the future through either financial hedges, physical hedges or not hedged at all will change from time to time in the discretion of our managing general partner and its affiliates and are not limited. If the hedges are with our managing general partner or its affiliates, rather than us, it is difficult to project what portion of these hedges will be allocated to us by our managing general partner because of uncertainty about the quantity, timing, and delivery locations of natural gas that may be produced by us. However, the allocations must be based on actual production in accordance with past practice.

Although hedging will provide us some protection against falling prices, these activities also could reduce the potential benefits of price increases and we could incur liability on the financial hedges. See Item 1A “Risk Factors — Risks Related to an Investment in Us — Future Hedging Activities We Anticipate Undertaking May Adversely Affect Our Financial Situation and Results of Operations” on page 24. We and the other partnerships sponsored by our managing general partner and its affiliates will be severally liable for our respective allocated share of the liabilities under any future hedging agreements, but will not be jointly and severally liable for the entire amount of the liabilities under the hedging agreements.

Crude oil produced from our wells will flow directly into storage tanks where it will be picked up by the oil company, a common carrier, or pipeline companies acting for the oil company which is purchasing the crude oil. Unlike natural gas, crude oil does not present any transportation problem. Our managing general partner anticipates selling any oil produced by our wells to regional oil refining companies at the prevailing spot market price for Appalachian crude oil in spot sales.

Subject to our managing general partner’s and its affiliates’ interest in their natural gas contracts, hedging arrangements, and pipelines and gathering systems, all benefits and liabilities from marketing and any other relationships affecting the property of our managing general partner or its affiliates or us must be fairly and equitably apportioned according to the interests of each in the property, consistent with past practice.

Major Customers. Our natural gas and oil is sold to various purchasers. For the period ended March 31, 2011, sales to Atmos Energy Marketing, LLC accounted for 87% of our total revenues. For the period ended December 31, 2010, sales to Atmos Energy Marketing, LLC accounted for 98% of our total revenues. No other customer accounted for more than 10% of our total revenues for the periods ended March 31, 2011 and December 31, 2010, respectively. As of March 31, 2011 and December 31, 2010, only 66% and 39%, respectively, of the total 110.14 net wells we currently expect to drill and complete were online and producing natural gas. Thus, the percentages of sales to our customers as set forth above should not be considered to be representative of our sales and customers after all of our wells are online and producing.

9

Competition. The energy industry is intensely competitive in all of its aspects. Competition arises not only from numerous domestic and foreign sources of natural gas and oil, but also from other industries that supply alternative sources of energy. In selling our natural gas and oil, product availability and price are our principal means of competition. We may also encounter competition in obtaining drilling and operating services from third-party providers. Any competition we encounter could delay the drilling and/or operating of our wells, and thus delay the distribution of our revenues to our participants. While it is impossible for us to accurately determine our comparative position in the natural gas and oil industry, we do not consider our operations to be a significant factor in the industry.

Markets. The availability of a ready market for natural gas and oil, and the price obtained, depend on numerous factors beyond our control as described below in Item 1A “Risk Factors — Risks Relating to Our Business” beginning on page 13. During fiscal years 2008, 2009, and 2010 our managing general partner did not experience problems in selling its and its affiliates’ natural gas and oil, although prices varied significantly during those periods.

Governmental Regulation

Regulation of Production. The production of natural gas and oil is subject to regulation under a wide range of local, state and federal statutes, rules, orders and regulations, such as requirements for permits for drilling operations, drilling bonds and reports concerning operations. Also, each state in which we drill a well has regulations governing conservation matters, including the regulation of well spacing. The effect of these regulations is to limit the number of wells, or the locations where we can drill wells, although we can apply for exemptions to the regulations to reduce the well spacing. The failure to comply with these rules and regulations can result in substantial penalties. Our competitors in the oil and natural gas industry are subject to the same regulatory requirements and restrictions that affect our operations.

Regulation of Transportation and Sale of Natural Gas. Governmental agencies regulate the production and transportation of natural gas. Generally, the regulatory agency in the state where a producing natural gas well is located supervises production activities and the transportation of natural gas sold into intrastate markets, and the Federal Energy Regulatory Commission (“FERC”) regulates the interstate transportation of natural gas.

Natural gas prices have not been regulated since 1993, and the price of natural gas is subject to the supply and demand for natural gas along with factors such as the natural gas’ BTU content and where the wells are located. Since 1985 FERC has sought to promote greater competition in natural gas markets in the United States. Traditionally, natural gas was sold by producers to interstate pipeline companies that served as wholesalers and resold the natural gas to local distribution companies for resale to end-users. FERC changed this market structure by requiring interstate pipeline companies to transport natural gas for third-parties. In 1992 FERC issued Order 636 and a series of related orders that required pipeline companies to, among other things, separate their sales services from their transportation services and provide an open access transportation service that is comparable in quality for all natural gas producers or suppliers. The premise behind FERC Order 636 was that the interstate pipeline companies had an unfair advantage over other natural gas producers or suppliers because they could bundle their sales and transportation services together. FERC Order 636 is designed to ensure that no natural gas seller has a competitive advantage over another natural gas seller because it also provides transportation services.

10

In 2000 FERC issued Order 637 and subsequent orders to enhance competition by removing price ceilings on short-term capacity release transactions. It also enacted other regulatory policies that were intended to enhance competition in the natural gas market and increase the flexibility of interstate natural gas transportation. FERC has further required pipeline companies to develop electronic bulletin boards to provide standardized access to information concerning capacity and prices.

Crude Oil Regulation. Oil prices are not regulated, and the price is subject to the supply and demand for oil, along with qualitative factors such as the gravity of the crude oil and sulfur content differentials.

State Regulation. Each state where we drill a well imposes a comprehensive statutory and regulatory scheme for natural gas and oil operations, including supervising the production activities and the transportation of natural gas sold in intrastate markets, which creates additional financial and operational burdens. For example, in our primary areas our oil and gas operations are regulated by the Department of Environmental Resources in Pennsylvania, the Department of Natural Resources in Indiana and the Department of Natural Resources and Environment in Michigan. Among other things, the regulations involve:

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

• landowner notification requirements;

• certain bonding or other security measures;

• minimum well spacing requirements;

• restrictions on well locations and underground gas storage;

• certain well site restoration, groundwater protection including water disposal plans, and safety measures;

• discharge permits for drilling operations;

• various reporting requirements; and

• well plugging standards and procedures.

Environmental Regulation. Our drilling and producing operations are subject to various federal, state, and local laws covering the discharge of materials into the environment, or otherwise relating to the protection of the environment. The Environmental Protection Agency and state and local agencies will require us to obtain permits and take other measures with respect to:

• the discharge of pollutants into navigable waters;

• disposal of wastewater; and

• air pollutant emissions, which may include CO² emissions from natural gas and oil wells.

11

If these requirements or permits are violated, there can be substantial civil and criminal penalties that will increase if there was willful negligence or misconduct. In addition, we may be subject to fines, penalties and unlimited liability for cleanup costs under various federal laws such as the Federal Clean Water Act, the Clean Air Act, the Resource Conservation and Recovery Act, the Oil Pollution Act of 1990, the Toxic Substance Control Act, and the Comprehensive Environmental Response, Compensation and Liability Act of 1980 for oil and/or hazardous substance contamination or other pollution caused by our drilling activities or our wells and our production activities.

Additionally, our liability can extend to pollution that occurred on our leases before we acquired the leases. Also, each state where we drill a well has either adopted federal standards or promulgated its own environmental 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. Although compliance may cause delays in drilling our wells, which we do not anticipate, or increase our costs, currently we do not believe these costs will be substantial. However, we cannot predict the ultimate costs of complying with present and future environmental laws and regulations because these laws and regulations are frequently changed, and ultimately they may have a material impact on our operations or costs to remain in compliance. Additionally, we cannot obtain insurance to protect against many types of environmental claims, including remediation costs.

Dismantlement, Restoration, Reclamation and Abandonment Costs. When we determine that a well is no longer capable of producing natural gas or oil in economic quantities, we must dismantle the well and restore and reclaim the surrounding area before we can abandon the well. We contract these operations to independent service providers to which we pay a fee. The contractor will also salvage the equipment on the well, which we then sell in the used equipment market.

ITEM 1A. RISK FACTORS

Statements made by us that are not strictly historical facts are “forward-looking” statements that are based on current expectations about our business and assumptions made by our managing general partner. These statements are subject to risks and uncertainties that exist in our operations and business environment that could result in actual outcomes and results that are materially different than those predicted.

Risks Relating to Our Business

Natural Gas and Oil Prices are Volatile and a Substantial Decrease in Prices, Particularly Natural Gas Prices, Would Decrease Our Revenues, Our Cash Distributions and the Value of Our Properties and Could Reduce Our Managing General Partner’s Ability to Loan Us Funds; Meet Its Ongoing Obligations to Indemnify Our Investor General Partners and Purchase Units Under Our Presentment Feature. A substantial decrease in natural gas and oil prices, particularly natural gas prices, would decrease our revenues and the value of our natural gas and oil properties. Our future financial condition and results of operations, and the value of our natural gas and oil properties, will depend on market prices for natural gas and, to a much lesser extent, oil. Further, if natural gas and oil prices decrease during the first years of production from our wells, which is when the wells typically achieve their greatest level of production, there would be a greater adverse effect on our distributions to our participants than price decreases in later years when the wells have a lower level of production. Also, our participants’ return level will decrease during our term, even if there are rising natural gas prices, because of reduced production volumes from our wells.

Prices for natural gas and oil are dictated by supply and demand factors and prices may fluctuate widely in response to relatively minor changes in the supply of and demand for natural gas or oil, and market uncertainty. For example, reduced natural gas demand and/or excess natural gas supplies will result in lower prices. Other factors affecting the price and/or marketing of natural gas and oil production, which are beyond our control and cannot be accurately predicted, are the following:

• the cost, proximity, availability, and capacity of pipelines and other transportation facilities;

• the price and availability of other energy sources such as coal, nuclear energy, solar and wind;

• the price and availability of alternative fuels, including when large consumers of natural gas are able to convert to alternative fuel use systems;

• local, state, and federal regulations regarding production, conservation, water disposal, and transportation;

• overall domestic and global economic conditions;

• the impact of the U.S. dollar exchange rates on natural gas and oil prices;

• technological advances affecting energy consumption;

• domestic and foreign governmental relations, regulations and taxation;

• the impact of energy conservation efforts;

• the general level of supply and market demand for natural gas and oil on a regional, national and worldwide basis;

• weather conditions and fluctuating seasonal supply and demand for natural gas and oil because of various factors such as home heating requirements in the winter months;

• economic and political instability, including war or terrorist acts in natural gas and oil producing countries, including those of the Middle East, Africa and South America;

• the amount of domestic production of natural gas and oil; and

13

• the amount and price of imports of natural gas and oil from foreign sources, including the actions of the members of the Organization of Petroleum Exporting Countries (“OPEC”), which include production quotas for petroleum products from time to time with the intent of increasing, maintaining, or decreasing price levels.

These factors make it extremely difficult to predict natural gas and oil price movements with any certainty. Price decreases would reduce the amount of our cash flow available for distribution to our participants and could make some of our reserves uneconomic to produce which would reduce our reserves and cash flow. Additionally, price decreases may cause the lenders under Atlas Energy, L.P.’s credit facility to reduce its borrowing base because of lower revenues or reserve values, which would indirectly reduce our managing general partner’s liquidity, and could possibly, require mandatory loan repayments from our managing general partner if Atlas Energy, L.P. and its other affiliates called on our managing general partner to do so. This would reduce our managing general partner’s ability to loan us money or to meet its ongoing partnership obligations, such as indemnification of our investor general partners for liabilities in excess of their pro rata share of our assets and insurance proceeds and purchasing Units presented by our participants.

Estimates of Our Natural Gas and Oil Reserves are Based on Many Assumptions that May Prove to be Inaccurate. Any Material Inaccuracies in these Underlying Assumptions Will Materially Affect the Quantities and Present Value of Our Reserves. Underground accumulations of natural gas and oil cannot be measured in an exact way. Natural gas and oil reserve engineering requires subjective estimates of underground accumulations of natural gas and oil and assumptions concerning future natural gas prices, production levels and operating and development costs. As a result, estimated quantities of proved reserves and projections of future production rates and the timing of development expenditures may prove to be inaccurate as discussed in Item 3 “Properties — Natural Gas and Oil Reserve Information” beginning on page 35. Any significant variance from these assumptions by actual figures could greatly affect estimates of reserves, the economically recoverable quantities of natural gas and oil, the classifications of reserves based on risk of recovery and estimates of the future net cash flows. Numerous changes over time to the assumptions on which our reserve estimates are based, as described above, will likely result in the actual quantities of natural gas and oil we ultimately recover being different from our reserve estimates.

The present value of future net cash flows from our proved reserves is not necessarily the same as the current market value of our estimated natural gas reserves. We base the estimated discounted future net cash flows from our proved reserves on historical prices and costs. However, the actual future net cash flows we derive from such properties also will be affected by factors such as:

• actual prices we receive for natural gas;

• the amount and timing of actual production;

14

• the amount and timing of our capital expenditures;

• supply of and demand for natural gas; and

• changes in governmental regulations or taxation.

The timing of both our production and incurrence of expenses in connection with the development and production of natural gas properties will affect the timing of actual future net cash flows from proved reserves, and thus their actual present value. In addition, the 10% discount factor we use when calculating discounted future net cash flows may not be the most appropriate discount factor based on interest rates in effect from time to time and risks associated with us or the natural gas and oil industry in general.

Any significant variance in our assumptions could materially affect the quantity and value of our reserves, the amount of PV-10 and standardized measure, and our financial condition and results of operations. In addition, our reserves or PV-10 and standardized measure may be revised downward or upward based upon production history, prevailing natural gas and oil prices and other factors. A material decline in prices paid for our production can reduce the estimated volumes of our reserves because the economic life of our wells could end sooner. Similarly, a decline in market prices for natural gas or oil may reduce our PV-10 and standardized measure.

Our Managing General Partner Has Limited Experience in Drilling Horizontal Wells to the Marcellus Shale and Horizontal Wells are More Expensive and Difficult to Drill and Complete Than Vertical Wells. As of March 31, 2011, our managing general partner had participated in drilling and served as operator on approximately 31 horizontal wells in the Marcellus Shale, which does not include the 12 horizontal Marcellus Shale wells it is drilling on our behalf. In addition, horizontal wells in the Marcellus Shale are more expensive to drill and complete than vertical wells, because of increased costs associated with the drilling rigs needed to drill a horizontal well, including fracing the wells, and casing for the wells. For example, in the Marcellus Shale, a horizontal well may cost three times the amount of a vertical well and this increased cost to us may not result in greater recoverable reserves. Also, horizontal wells will be more susceptible to mechanical problems associated with completing the wells, such as casing collapse and lost equipment in the wellbore, than vertical wells. Further, fracing the formation in a horizontal well is more complicated than fracing the same geological formation in a vertical well. Thus, there is a greater risk of loss of the well or cost overruns associated with horizontal drilling as compared with vertical drilling.

15

Drilling Our Wells Requires Adequate Sources of Water to Facilitate the Fracturing Process and Our Production Operations Result in Removing Water from Our Wells that We Must Dispose Of. If We are Unable to Dispose of the Water We Remove from a Well at a Reasonable Cost and Within Applicable Environmental Rules, Our Ability to Produce Natural Gas from the Well Could Be Impaired. Our natural gas wells in the Marcellus Shale primary area use a process called hydraulic fracturing, which requires large amounts of water to frac the wells and also results in water discharges that must be treated and disposed of. Environmental regulations governing the injection, withdrawal, storage and use of surface water or groundwater necessary for hydraulic fracturing may increase operating costs and cause delays, interruptions or termination of operations, the extent of which cannot be predicted, all of which could have an adverse effect on our operations and financial performance. For example, before we can drill a well to the Marcellus Shale in Pennsylvania using hydraulic fracturing our well permit application to the Pennsylvania Department of Environmental Protection (“the Pennsylvania DEP”) must, among other things:

• disclose our plans for using casing (e.g. steel pipe) in the well and cementing the casing in place through all fresh water aquifers before drilling to deeper natural gas formations in order to protect groundwater from contamination by natural gas or frac fluid produced from the well;

• disclose the source and location of the water we will use;

• identify where wastewater produced from the well will be stored, treated and disposed of;

• disclose our plans for any pits to temporarily store water for our drilling activities, which must be constructed in accordance with the Pennsylvania DEP standards (e.g. synthetic liners); and

• submit reports to the Pennsylvania DEP on well completion, waste management, annual production, and plugging and abandonment.

Our ability to remove and dispose of water will affect our production, and the cost of water treatment and disposal may affect our profitability.

New federal and state environmental regulations, in addition to those discussed above, could be imposed that would include restrict our ability to conduct hydraulic fracturing or dispose of water, drilling fluids and other substances associated with the exploration, development and production of natural gas and oil. In this regard, the U.S. Environmental Protection Agency (“EPA”) is studying the potential impact of hydraulic fracturing on drinking water, however, the initial results of this study are not expected by the EPA until late 2012, which will be after all of our drilling activities will be completed.

Drilling Wells is Highly Speculative and Some of Our Wells Are Nonproductive or May Be Productive, But Fail to Return the Costs of Drilling and Operating Them. The amount of recoverable natural gas and oil reserves may vary significantly from well to well. We have drilled some wells that are nonproductive (i.e. “dry holes”), and we may drill more nonproductive wells or wells that may be profitable on an operating basis, but do not produce sufficient net revenues to return a profit after drilling, operating and other costs are taken into account. The geologic data and technologies available do not allow us to know conclusively before drilling a well whether or not natural gas or oil is present or can be produced economically.

16

The cost of drilling, completing and operating a well is often uncertain. For example, the increase in natural gas and oil prices over the last several years has increased the demand for drilling rigs and other related equipment, and the costs of drilling and completing natural gas and oil wells also have increased. This has increased our well costs since our wells are drilled by our managing general partner, serving as our general drilling contractor, on a modified cost plus basis, and are not drilled on a turnkey basis for a fixed price that would shift the risk of cost overruns to our managing general partner as drilling contractor. Thus, any cost overruns in drilling and completing our wells could reduce or delay distributions to our participants.

The Drilling of Some of Our Wells Could Be Curtailed, Delayed or Cancelled If Unexpected Events Occur. Some of our drilling operations may be curtailed, delayed or cancelled as a result of many factors, including:

• title problems;

• environmental or other regulatory concerns;

• costs of, or shortages or delays in the availability of, oil field services and equipment;

• unexpected drilling conditions;

• unexpected geological conditions;

• adverse weather conditions;

• equipment failures or accidents;

• limitations on or disruptions in gathering or transmission capacity;

• environmental accidents such as gas leaks, ruptures or discharges of toxic gases, brine or well fluids into the environment or oil leaks, including groundwater contamination;

• fires, blowouts, craterings and explosions; and

• uncontrollable flows of natural gas or well fluids.

As discussed in Item 3 “Properties,” beginning on page 34, all of our wells are not yet completed and online. Any one or more of the factors discussed above could reduce or delay our receipt of a portion, which could be significant, of our natural gas and oil production revenues, thereby reducing or delaying our revenues and our distributions to our participants. In addition, any of these events can cause substantial losses, including personal injury or loss of life, damage to or destruction of property, natural resources and equipment, pollution, environmental contamination, loss of wells and regulatory penalties.

Although we maintain insurance against various losses and liabilities arising from our operations, insurance against all operational risks will not be available to us. Additionally, we may elect not to obtain insurance if we believe that the cost of available insurance is excessive relative to the perceived risks presented. Losses could, therefore, occur for uninsurable or uninsured risks or in amounts in excess of existing insurance coverage. The occurrence of an event that is not fully covered by insurance could reduce our results of operations.

17

If Third-Parties Participating in Drilling Some of Our Wells Fail to Pay Their Share of the Well Costs, We Would Have to Pay Those Costs in Order to Get the Wells Drilled, and If We Are Not Reimbursed the Increased Costs Would Reduce Our Cash Flow and Possibly Could Reduce the Number of Wells We Can Drill. Third-parties have participated with us in drilling some of our wells. Financial risks exist when the cost of drilling, equipping, completing, and operating wells is shared by more than one person. If we pay our share of the costs, but the other interest owner does not pay its share of the costs, then we would have to pay the costs of the defaulting party. In this event, we would receive the defaulting party’s revenues from the well, if any, under penalty arrangements set forth in the operating agreement, which may, or may not, be sufficient to cover the additional costs we paid. If it is insufficient to cover the additional costs, the increased costs would reduce our cash flow and the number of wells we can drill unless we borrow funds to cover the additional costs or the costs of drilling our other wells is less than expected and those excess funds are used to pay the additional costs.

Risks Related to an Investment In Us

An Investment in Us Must be for the Long-Term Because the Units Are Illiquid and Not Readily Transferable. If you invest in us, then you must assume the risks of an illiquid investment. The transferability of the Units is limited by the securities laws, the tax laws, and the partnership agreement. The Units generally cannot be liquidated since there is no readily available market for the sale of the Units. Further, we do not intend to list our Units on any exchange.

Also, a sale of your Units could create adverse tax and economic consequences for you. The sale or exchange of all or part of your Units held for more than 12 months generally will result in a recognition of long-term capital gain or loss. However, previous deductions for depreciation, depletion and intangible drilling costs may be recaptured as ordinary income rather than capital gain regardless of how long you have owned your Units. Also, your pro rata share of our liabilities, if any, as of the date of the sale or exchange of your Units must be included in the amount realized by you. Thus, the gain recognized by you may result in a tax liability greater than the cash proceeds, if any, received by you from the sale or other disposition of your Units, if permitted under the partnership agreement.

Our Managing General Partner’s Management Obligations to Us Are Not Exclusive, and if It Does Not Devote the Necessary Time to Our Management There Could Be Delays in Providing Timely Reports and Distributions to Our Participants, and Our Managing General Partner, Serving as Operator of Our Wells, May Not Supervise the Wells Closely Enough. We do not have any officers, directors or employees. Instead, we rely totally on our managing general partner and its affiliates for our management. Our managing general partner is required to devote to us the time and attention that it considers necessary for the proper management of our activities. However, our managing general partner and its affiliates currently are, and will continue to be, engaged in other natural gas and oil activities, including other partnerships and unrelated business ventures for their own account or for the account of others, during our term. This creates a continuing conflict of interest in allocating management time, services, and other activities among us and its other activities. If our managing general partner does not devote the necessary time to our management, there could be delays in providing timely annual and semi-annual reports, tax information and cash distributions to our participants. Also, if our managing general partner, serving as the operator of our wells, does not supervise the wells closely enough, for example, there could be delays in undertaking remedial operations on a well, if necessary to increase the production of natural gas from the well.

18

Current Conditions May Change and Reduce Our Proved Reserves, Which Could Reduce Our Revenues. A participant will be able to recover his investment in us only through our distribution of our net sales proceeds from the production of natural gas and oil from our productive wells. The quantity of natural gas and oil in a well, which is referred to as its reserves, decreases over time as the natural gas and oil is produced until the well is no longer economical to operate. Our proved reserves will decline as they are produced from our wells, and once all of our wells are online our distributions to our participants generally will decrease each year until our wells are depleted.

Our proved reserves at December 31, 2010 from the wells we drilled, completed and placed online for production in 2010 are set forth in Item 3 “Properties — Natural Gas and Oil Reserve Information” beginning on page 35. However, there is an element of uncertainty in all estimates of proved reserves, and current conditions, such as natural gas and oil prices and the costs of operating our wells and transporting our natural gas, will change in the future and could reduce the amount of our current proved reserves. Also, our estimated proved reserves and revenues from the sale of our natural gas and oil production once all of our wells have been drilled and placed online for production will vary significantly from our expectations associated with the estimated proved reserves of only the wells we drilled, completed and placed online for production in 2010 as presented in Item 3 “Properties — Natural Gas and Oil Reserve Information” beginning on page 35.

We base our estimates of proved natural gas and oil reserves and future net revenues from those reserves on various assumptions, including those required by the SEC, such as natural gas and oil prices, taxes, development expenses, capital expenses, operating expenses and availability of funds. Any significant variance in the future in these assumptions based on actual production, natural gas and oil prices, taxes, development expenses, operating expenses, availability of funds, would materially affect the estimated quantity of our reserves as discussed in Item 3 “Properties” beginning on page 34.

Our properties also may be susceptible to hydrocarbon drainage from wells on adjacent properties in which we do not have an interest. In addition, our proved reserves may be revised downward in the future based on the following:

• the actual production history of our wells;

• results of future exploration and development in the area;

• decreases in natural gas and oil prices;

• governmental regulation; and

• other changes in current conditions, many of which are beyond our control.

19

Government Regulation of the Oil and Natural Gas Industry is Stringent and Could Cause Us to Incur Substantial Unanticipated Costs for Regulatory Compliance, Environmental Remediation of Our Well Sites (Which May Not Be Fully Insured) and Penalties, and Could Delay or Limit Our Drilling Operations. We are subject to complex laws that can affect the cost, manner or feasibility of doing business. Exploration, development, production and sales of natural gas and oil are subject to extensive federal, state and local regulations. We discuss our regulatory environment in more detail in Item 1 “Business — Governmental Regulation” beginning on page 10. We may be required to make large expenditures to comply with these regulations. Failure to comply with these regulations may result in the suspension or termination of our operations and subject us to administrative, civil and criminal penalties. Also, governmental regulations could change in ways that substantially increase our costs, thereby reducing our return on invested capital, revenues and net income.

In addition, our operations may cause us to incur substantial liabilities to comply with environmental laws and regulations. Our natural gas and oil operations are subject to stringent federal, state and local laws and regulations relating to the release or disposal of materials into the environment or otherwise relating to environmental protection. These laws and regulations:

• require the acquisition of a permit before drilling begins;

• restrict the types, quantities, and concentration of substances that can be released into the environment in connection with drilling and production activities;

• limit or prohibit drilling activities on certain lands lying within wilderness, wetlands, and other protected areas; and

• impose substantial liabilities for pollution resulting from our operations.

These laws include, for example:

• the federal Clean Air Act and comparable state laws and regulations that impose obligations related to air emissions;

• the federal Clean Water Act and comparable state laws and regulations that impose obligations related to discharges of pollutants into regulated bodies of water;

• the Resource Conservation and Recovery Act (“RCRA”) and comparable state laws that impose requirements for the handling and disposal of waste, including waste water produced from our wells; and

• the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”) and comparable state laws that regulate the cleanup of hazardous substances produced from our wells.

Failure to comply with these laws and regulations may result in the following:

• assessment of administrative, civil, and criminal penalties;

20

• incurrence of investigatory or remedial obligations; or

• imposition of injunctive relief.

Changes in environmental laws and regulations occur frequently, and any changes that result in more stringent or costly waste handling, storage, transporting, disposal or cleanup requirements could require us to make significant expenditures to maintain compliance or could restrict our methods or times of operation. Under these environmental laws and regulations, we could be held strictly liable for the removal or remediation of previously released materials or property contamination regardless of whether we were responsible for the release or if our operations were standard in the industry at the time they were performed. Pollution and environmental risks generally are not fully insurable. The occurrence of an event that is not covered, or not fully covered, by insurance could reduce our revenues and the value of our assets.

Our Natural Gas and Oil Activities Are Subject to Drilling and Operating Hazards Which Could Result in Substantial Losses to Us. Well blowouts, cratering, explosions, uncontrollable flows of natural gas, oil or well fluids, fires, formations with abnormal pressures, pipeline ruptures or spills, pollution, releases of toxic gas and other environmental hazards and risks are inherent drilling and operating hazards for us. The occurrence of any of those hazards could result in substantial losses to us, including liabilities to third-parties or governmental entities for damages resulting from the occurrence of any of those hazards and substantial investigation, litigation and remediation costs.

Our Total Annual Cash Distributions During Our First Five Years May be Less Than $10,000 Per Unit, Even With Subordination. If our participants’ cash distributions from us are less than 12% of capital ($2,400 per $20,000 unit) in the first 12-month subordination period, 10% of capital ($2,000 per $20,000 unit) in each of the next three 12- month subordination periods, and 8% of capital ($1,600 per $20,000 unit) in the fifth 12-month subordination period based on a $20,000 Unit regardless of the actual price paid) for the 60-month aggregate subordination period beginning when natural gas or oil is being sold from at least 75% of our wells, then our managing general partner has agreed to subordinate a portion of its share of our net production revenues. However, if our wells produce only small natural gas and oil volumes, and/or natural gas and oil prices decrease, then even with subordination our participants may not receive the return of capital in each of the five 12-month subordination periods described above. Also, at any time during the 60-month aggregate subordination period our managing general partner is entitled to an additional share of our revenues to recoup previous subordination distributions to the extent our participants’ cash distributions from us would exceed the return of capital described above. A more detailed discussion of our managing general partner’s subordination obligation is set forth in Item 11 “Description of Registrant’s Securities to be Registered — Distributions and Subordination” beginning on page 61.

21

Our Limited Operating History Creates Greater Uncertainty Regarding Our Ability to Operate Profitably. Our limited history of operating our wells may not indicate the results that we may achieve in the future. Our success depends on generating sufficient revenues by producing sufficient quantities of natural gas and oil from our wells and then marketing that natural gas and oil at sufficient prices to pay the operating costs of our wells and our administrative costs of conducting business as a partnership, and still provide a reasonable rate of return on our participants’ investment in us. If we are unable to pay our costs, then we may need to:

• borrow funds from our managing general partner, which is not contractually obligated to make any loans to us;

• shut-in or curtail production from some of our wells; or

• attempt to sell some of our wells, which we may not be able to do on terms that are acceptable to us.

Also, the events set forth below could decrease our revenues from our wells and/or increase our expenses of operating our wells:

• decreases in the price of natural gas and oil, which are volatile;

• changes in the oil and gas industry, including changes in environmental regulations, which could increase our costs of operating our wells in compliance with any new environmental regulations;

• an increase in third-party costs for equipment or services, or an increase in gathering and compression fees for transporting our natural gas production; and

• problems with one or more of our wells, which could require repairing or performing other remedial work on a well or providing additional equipment for the well.

Competition May Reduce Our Revenues from the Sale of Our Natural Gas. Competition arises from numerous domestic and foreign sources of natural gas and oil, including other natural gas producers and marketers in the Appalachian Basin, Indiana, and Michigan as well as competition from other industries that supply alternative sources of energy. Competition will make it more difficult to market our natural gas. Product availability and price are the principal means of competition in selling natural gas and oil. Many of our competitors possess greater financial or other resources than we do, which may enable them to offer their natural gas to natural gas purchasers on terms, such as lower prices or a greater volume of natural gas that can be delivered to the purchaser that we cannot match. Also, other energy sources such as coal may be available to the purchasers at a lower price. As a result, we may have to seek other natural gas purchasers and we may receive lower prices for our natural gas and incur higher transportation and compression fees if we sell our natural gas to these other natural gas purchasers. In this event, our revenues from the sale of our natural gas would be reduced.

22

We May Have to Replace Our Natural Gas Purchasers and Receive a Lower Price for Our Natural Gas. We will depend on a limited number of natural gas purchasers to purchase the majority of our natural gas production. For example, for the periods ended December 31, 2010 and March 31, 2011, sales to Atmos Energy Marketing, LLC accounted for 98% and 87%, respectively, of our total revenues. Further, we will not be guaranteed a specific natural gas price, unless we engage in hedging in the future. Thus, if our current purchasers were to pay a lower price for our natural gas in the future, our revenues would decrease. Also, if our current purchasers began buying a reduced percentage of our natural gas, or stopped buying any of our natural gas, the sale of our natural gas would be delayed until we found other purchasers, and the substitute purchasers we found may pay lower prices for our natural gas, which would reduce our revenues.

We Could Incur Delays in Receiving Payment, or Substantial Losses if Payment is Not Made, for Natural Gas We Previously Delivered to a Purchaser, Which Could Delay or Reduce Our Revenues and Cash Distributions. There is a credit risk associated with a natural gas purchaser’s ability to pay. We may not be paid or may experience delays in receiving payment for natural gas that has already been delivered. In this event, our revenues and cash distributions to our participants also would be delayed or reduced. In accordance with industry practice, we typically will deliver natural gas to a purchaser for a period of up to 60 to 90 days before we receive payment. Thus, it is possible that we may not be paid for natural gas that already has been delivered if the natural gas purchaser fails to pay for any reason, including bankruptcy. This ongoing credit risk also may delay or interrupt the sale of our natural gas.

We Intend to Produce Natural Gas and/or Oil from Our Wells Until They Are Depleted, Regardless of Any Changes in Current Conditions, Which Could Result in Lower Returns to Our Participants as Compared With Other Types of Investments Which Can Adapt to Future Changes Affecting Their Portfolios. Our natural gas and oil properties are relatively illiquid because there is no public market for working interests in natural gas and oil wells. In addition, one of our investment objectives is to continue to produce natural gas and oil from our wells until the wells are depleted. Thus, unlike mutual funds, for example, which can vary their portfolios in response to changes in future conditions, we do not intend, and in all likelihood we would be unable, to vary our portfolio of wells in response to future changes in economic and other conditions such as decreases or increases in natural gas or oil prices, or increased operating costs of our wells.

Since Our Managing General Partner Is Not Contractually Obligated to Loan Funds to Us, We Could Have to Curtail Operations or Sell Properties if We Need Additional Funds and Our Managing General Partner Does Not Make a Loan to Us. Our revenues from the sale of our natural gas and oil production may be insufficient to pay all of our ongoing expenses, such as our operating and maintenance costs for our productive wells or our costs associated with repairing or performing other remedial work on a well. If this were to occur, we expect that we would borrow the necessary funds from our managing general partner or its affiliates, although they are not contractually committed to make a loan. Also, under our partnership agreement the amount we may borrow may not at any time exceed 5% of our total subscriptions and no borrowings are permitted from third-parties. If, for any reason, our managing general partner did not loan us the funds needed to repair or perform other remedial work on a well, then we might have to curtail operations on the well or attempt to sell the well, although we may not be able to do so on terms that are acceptable to us.

23

Future Hedging Activities We Anticipate Undertaking May Adversely Affect Our Financial Situation and Results of Operations. Because the majority of our proved reserves are currently natural gas reserves, we are more susceptible to movements in natural gas prices. Although currently none of our natural gas is hedged to protect against a decrease in natural gas prices, we expect to engage in hedging activities in the future, as we have done in the past, to help protect us if natural gas prices fall in the future. However, our future hedging activities could reduce the potential benefits of price increases and we could incur liability on financial hedges. For example, we would be exposed to the risk of a financial loss if any of the following occurred:

• our production is substantially less than expected;

• the counterparties to the futures contracts fail to perform under the contracts; or

• there is a sudden, unexpected event materially impacting natural gas prices.

Increases in Prices for Natural Gas and Oil Could Result in Non-Cash Balance Sheet Reductions Due to the Accounting Treatment of Derivative Contracts We Expect to Enter Into in the Future. In conjunction with the “Asset Acquisition” and “Chevron Merger” described in Item 5 “Directors and Executive Officers — Managing General Partner,” beginning on page 38, Atlas Energy, Inc. monetized all of its derivative contracts related to natural gas and oil production. We and the other partnerships sponsored by our managing general partner, including future partnerships, will share in the total available hedge gains based on each partnership’s actual production volumes during the period of the original derivative contracts, some of which extended into 2014. In addition, we anticipate that in the future we will enter into natural gas derivative contracts, either through Atlas Energy or an affiliate or directly for our own account, and we will account for these derivative contracts by applying the provisions of Accounting Standards Codification 815, “Derivatives and Hedging.” Due to the mark-to-market accounting treatment for these contracts, we could recognize incremental hedge liabilities between reporting periods resulting from increases in reference prices for natural gas and oil, which could result in us recognizing a non-cash loss in our accumulated other comprehensive income (loss) and a consequent non-cash decrease in our partners’ equity between reporting periods. Any such decrease could be substantial.

A Decrease in Natural Gas Prices Could Subject Our and Our Managing General Partner’s Oil and Gas Properties to an Impairment Loss under Generally Accepted Accounting Principles. Generally accepted accounting principles require oil and gas properties and other long-lived assets to be reviewed for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. Long-lived assets are reviewed for potential impairments at the lowest levels for which there are identifiable cash flows that are largely independent of other groups of assets. We and our managing general partner will test our respective oil and gas properties on a field-by-field basis by determining if the historical cost of proved properties less the applicable accumulated depletion, depreciation and amortization and abandonment is less than the estimated expected undiscounted

24

future cash flows. The expected future cash flows are estimated based on our or our managing general partner’s own economic interests and our respective plans to continue to produce and develop proved reserves. Expected future cash flow from the sale of production of reserves is calculated based on estimated future prices. We and our managing general partner estimate prices based on current contracts in place at the impairment testing date, adjusted for basis differentials and market related information, including published futures prices. 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. Accordingly, declines in the price of natural gas have caused the carrying values of properties in many of our managing general partner’s previous partnerships to exceed the expected future cash flow. Future declines in the price of natural gas may cause the carrying value of our, our managing general partner’s or its other partnerships’ oil and gas properties to exceed the expected future cash flows, and require an impairment loss to be recognized.

Federal Income Tax Risks.

Changes in the Law May Reduce Our Participants’ Tax Benefits From an Investment in Us. Our participants’ tax benefits from their investment in us may be affected by changes in the tax laws. For example, President Obama’s administration has proposed, among other tax changes, the repeal of certain oil and gas tax benefits, beginning in 2012, including the repeal of the percentage depletion allowance. This proposal may or may not be enacted into law. The repeal of the percentage depletion allowance, if it happens, however, would result in a decrease in our participants’ future tax benefits from their investment in us.

Our Participants’ Deduction for Intangible Drilling Costs May Be Limited for Purposes of the Alternative Minimum Tax. Under current tax law, our participants’ alternative minimum taxable income in 2010 cannot be reduced by more than 40% by their respective shares of our deduction for intangible drilling costs without creating a tax preference item under the alternative minimum tax rules.

Our Limited Partners Need Passive Income to Use Their Deduction for Intangible Drilling Costs. If a participant invested in us as a limited partner (except as discussed below), his or her share of our deduction for intangible drilling costs in 2010 will be a passive loss that cannot be used to offset “active” income, such as salary and bonuses, or portfolio income, such as dividends and interest income. Thus, a limited partner may not have enough passive income from us or net passive income from his or her other passive activities, if any, in 2010 to offset a portion or all of the limited partner’s passive deduction for intangible drilling costs in 2010. However, any unused passive loss from intangible drilling costs may be carried forward indefinitely to offset passive income in subsequent taxable years. Also, except as described below, the passive activity limitations do not apply to a limited partner that is a C corporation which:

• is not a personal service corporation or a closely held corporation;

• is a personal service corporation in which employee-owners hold 10% (by value) or less of the stock, but is not a closely held corporation; or

• is a closely held corporation (i.e., five or fewer individuals own more than 50% (by value) of the stock), but is not a personal service corporation in which employee-owners own more than 10% (by value) of the stock, in which case passive losses may be used to offset net active income (calculated without regard to passive activity income and losses or portfolio income and losses).

25

Our Participants May Owe Taxes in Excess of Their Cash Distributions from Us. Our participants may become subject to income tax liability for their respective shares of our income in any taxable year in an amount that is greater than the cash they receive from us in that taxable year. For example:

• if we borrow money, our participants’ share of our revenues used to pay principal on the loan will be included in their share of our income and will not be deductible;

• income from sales of natural gas and oil may be included in our participants’ income from us in one tax year, even though payment is not actually received by us and, thus, cannot be distributed to our participants until the next tax year;

• if there is a deficit in a participant’s capital account, we may allocate income or gain to the participant even though the participant does not receive a corresponding distribution of our revenues;

• our revenues may be expended by our managing general partner for nondeductible costs or retained in us to establish a reserve for future estimated costs, including a reserve for the estimated costs of eventually plugging and abandoning our wells, which will reduce our participants’ cash distributions from us without a corresponding tax deduction; and

• the taxable disposition of our property or our participants’ Units may result in income tax liability to our participants in excess of the cash they receive from the transaction.

Investment Interest Deductions of Investor General Partners May Be Limited. If a participant invested in us as an investor general partner, his or her share of our deduction for intangible drilling costs in 2010 will reduce the participant’s investment income and may limit the amount of the participant’s deductible investment interest expense, if any.

Our Participants’ Tax Benefits from an Investment in Us Are Not Contractually Protected. An investment in us does not give our participants any contractual protection against the possibility that part or all of the intended tax benefits of their investment will be disallowed by the IRS. No one provides any insurance, tax indemnity or similar agreement for the tax treatment of our participants’ investment in us. Our participants have no right to rescind their investment in us or to receive a refund of any of their investment in us if a portion or all of the intended tax consequences of their investment in us is ultimately disallowed by the IRS or the courts. Also, none of the fees paid by us to our managing general partner, its affiliates or independent third-parties (including special counsel which issued the tax opinion letter) are refundable or contingent on whether the intended tax consequences of their investment in us are ultimately sustained if challenged by the IRS.

26

An IRS Audit of Us May Result in an IRS Audit of the Personal Federal Income Tax Returns of Our Participants. The IRS may audit our annual federal information income tax returns, particularly since our participants will be eligible to claim a deduction for intangible drilling costs in 2010. If we are audited, the IRS also may audit the personal federal income tax returns of a portion or all of our participants, including prior years’ returns and items that are unrelated to us.

Our Deductions May be Challenged by the IRS. If the IRS audits us, it may challenge the amount of our deductions and the taxable year in which the deductions were claimed, including the deductions for intangible drilling costs and depreciation. Any adjustments made by the IRS to our federal information income tax returns could lead to adjustments on the personal federal income tax returns of our participants and could reduce the amount of their deductions from us in 2010 and subsequent tax years. The IRS also could seek to recharacterize a portion of our intangible drilling costs for drilling and completing our wells as some other type of expense, such as lease costs or equipment costs, which would reduce or defer our participants’ share of our deductions for those costs.

We define EBITDA as earnings before interest, taxes, depreciation, depletion and amortization. EBITDA is not a measure of performance calculated in accordance with accounting principles generally accepted in the United States of America or GAAP. Although not prescribed under GAAP, we believe the presentation of EBITDA is relevant and useful because it helps our participants to understand our operating performance and makes it easier to compare our results with other companies that have different financing and capital structures or tax rates. EBITDA should not be considered in isolation from, or as a substitute for, our net income as an indicator of operating performance or cash flows from operating activities as a measure of liquidity. EBITDA, as we calculate it, may not be comparable to EBITDA measures reported by other companies. In addition, EBITDA does not represent funds available for discretionary use. The following reconciles EBITDA to our income from continuing operations for the periods indicated.

This Item 2 “Financial Information” section beginning on page 27, should be read in conjunction with Item 13 “Financial Statements and Supplementary Data — Notes to Financial Statements,” beginning on page 77.

Overview. The following discussion provides information to assist in understanding our financial condition and result of operations. We have drilled and currently operate wells located in Pennsylvania, Indiana, Michigan, and Colorado and are currently drilling additional development wells in the same primary areas. Our operating cash flows are generated from our wells, which produce primarily natural gas, but also some oil. Our produced natural gas and oil is then delivered to market through affiliated or third-party gas gathering systems. 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 managing general partner, as operator, a monthly well supervision fee, which covers all normal and regularly recurring operating expenses for the production and sale of natural gas and oil such as:

• well tending, routine maintenance and adjustment;

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

• preparation of reports for us and 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 cost for third-party services, materials, and a competitive charge for services performed directly by our managing general partner or its affiliates. Also, beginning one year after each of our wells has been placed into production our managing general partner, as operator, may retain $200 per month, per well to cover the estimated future plugging and abandonment costs of the well. As of March 31, 2011, our managing general partner had not withheld any funds for this purpose.

Our managing general partner intends to produce our wells 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.

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 managing general partner is responsible for selling our natural gas production. During 2011 and 2010, 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.

29

Results of Operations. Partnership operations began in April 1, 2010 (commencement of operations). Therefore, no comparative data is available for the period ended December 31, 2010.

The following table sets forth information for the period April 1, 2010 (commencement of operations) through December 31, 2010 relating to revenues recognized, costs and expenses incurred, daily production volumes, average sales prices, and production cost per equivalent unit during the period indicated:

	For the Period April 1, 2010
	(commencement of operations)
	through December 31, 2010
Revenues (in thousands):
Gas(1)	$	2,160
Oil	$	—
Production volumes:
Gas (thousands of cubic feet (mcf)/day)		2,177
Oil (barrels (bbls)/day)		—
Average sales price:
Gas (per mcf)	$	4.72
Oil (per bbl)	$	—
Production costs:
As a percent of sales		46	%
Per equivalent mcf	$	2.19
Depletion per mcfe	$	4.90

(1) Excludes sales of residual gas and sales to landowners.

Natural Gas Revenues. Our natural gas revenues were $2,159,900 for the period April 1, 2010 through December 31, 2010. We expect that our natural gas revenues will increase over the next year as more of our wells are put online and are producing larger volumes of natural gas.

Expenses. Production expenses were $1,000,600 for the period April 1, 2010 through December 31, 2010. Included is $222,300 of operating fees paid to our managing general partner.

General and administrative expenses were $40,500 for the period April 1, 2010 through December 31, 2010. These expenses include third-party costs, audit, tax and other outside services as well as the monthly administrative fees charged by our managing general partner, and vary from year to year due to the timing and billing of the costs and services provided to us.

30

Liquidity and Capital Resources. Cash used in investing activities was $149,724,600 for the period ended December 31, 2010, which was paid to our managing general partner, serving as general drilling contractor, to drill and complete all of our wells pursuant to our drilling and operating agreement. As of December 31, 2010 we had drilled and completed 52 gross wells, which is 45.03 net wells that were online for the sale of production. In addition to the wells we drilled during 2010, our participants’ share of our estimated drilling and equipment costs of 68 gross wells, which is 67.11 net wells, were prepaid by us in 2010 for wells to be drilled in 2011. The drilling of each of the wells we prepaid in 2010 began on or before March 31, 2011, and was not delayed by any shortages of drilling rigs, equipment, supplies or personnel. Cash provided by financing activities was $149,724,600 which came from capital contributions for the period ended December 31, 2010.

Our managing general partner believes that we have adequate capital to develop approximately 127 gross wells under our drilling and operating agreement. Our wells will be drilled primarily in western Pennsylvania, central Indiana, and northern Michigan. Funds contributed by our participants and our managing general partner after our formation will be the only funds available to us for drilling activities. Although we estimate that 127 gross development wells will be drilled, we cannot guarantee that all of our proposed wells will be drilled or completed since there may be cost overruns in drilling and completing the wells. Each of our proposed wells is unique and the ultimate costs incurred may be more or less than our current estimates.

Our ongoing operating and maintenance costs for the next 12-month period are expected by our managing general partner to be fulfilled through revenues from the sale of our gas and oil production. Natural gas prices are volatile and, for example, can be affected by weather conditions and fluctuating seasonal supply and demand for natural gas and oil. Also, our managing general partner has not experienced any problems with selling natural gas in the past three fiscal years as discussed in Item 1 “Business — General — Markets,” beginning on page 10. Although we do not anticipate that there will be a shortfall in our revenues that we use to pay for our ongoing expenses, if one were to occur, we expect that we would borrow the necessary funds from our managing general partner or its affiliates, which are not contractually committed to make a loan. The amount we may borrow may not at any time exceed 5% of our total subscriptions and no borrowings are permitted from third-parties.

We have not and will not devote any funds to research and development activities and no new products or services will be introduced. We do not plan to sell any of our wells and intend to continue to produce them until they are depleted at which time they will be plugged and abandoned. We have no employees and rely on our managing general partner and its affiliates for management.

31

Critical Accounting Policies. The discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of our assets, liabilities, revenues and costs and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related to oil and gas reserves and certain accrued liabilities. We base our estimates on our managing general partner’s historical experience and on various other assumptions that we believe are 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.

We have identified the following policies as critical to our business operations and understanding the results of our operations. For a detailed discussion on the application of these and other accounting policies, see Note 2 in Item 13 “Financial Statements and Supplementary Data — Notes to Financial Statements” beginning on page 77.

Use of Estimates. Preparation of the 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 consolidated financial statements and the reported amounts of revenues and costs and expenses during the reporting period. Actual results could differ from these estimates.

Reserve Estimates. Our estimates of our proved natural gas and oil reserves and our 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 and oil 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 and oil reserves will be inherently imprecise. Actual future production, natural gas and oil prices, revenues, taxes, development expenditures, operating expenses and quantities of recoverable natural gas and oil reserves may vary substantially from our estimates or the 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 and oil prices, mechanical difficulties, governmental regulation and other factors, many of which are beyond our control.

Impairment of Oil and Gas Properties. We will 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 will estimate the expected future cash flows from our oil and gas properties and compare the 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 and impairments may be required in the future.

32

Dismantlement, Restoration, Reclamation and Abandonment Costs. On a periodic 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 on abandonment as discussed in Note 5 to our financial statements in Item 13 “Financial Statements and Supplementary Data — Notes to Financial Statements” on page 83. To cover any shortfall between our participants’ share of the salvage value of the equipment in a well and their share of the plugging and abandoning costs of the well, our managing general partner has the right, beginning one year after each well begins producing, to retain up to $200 per month of our revenues in partnership reserves to cover future plugging and abandonment costs of the well. This $200 also includes our managing general partner’s share of revenues to cover its share of the plugging and abandonment costs of the well. As of December 31, 2010, no reserve for this purpose had been established. A decrease in salvage values or an increase in dismantlement, restoration, reclamation and abandonment costs could reduce our gross profit from energy operations.

Commodity Price Risk. Our major market risk exposure in commodities is fluctuations in the pricing of our natural gas and oil production. Realized pricing is primarily driven by the prevailing worldwide prices for crude oil and spot market prices applicable to United States natural gas production. Pricing for natural gas and oil production has been volatile and unpredictable for many years. Currently, none of our natural gas production is subject to hedging arrangements. Instead, our production is being sold at contract prices in the month produced or at spot market prices. In this regard, the prices under most of our natural gas sales contracts are negotiated on an annual basis and are index-based. Also, in conjunction with the “Asset Acquisition” and the “Chevron Merger” described in Item 5 “Directors and Executive Officers — Managing General Partner,” beginning on page 38, Atlas Energy, Inc. monetized all derivative contracts related to natural gas and oil production, and we and the other partnerships sponsored by our managing general partner will share in the total available hedge gains based on each of each partnership’s actual production volumes during the period of the original derivative contracts.

To limit our exposure to a decrease in natural gas prices, we have used hedges in the past, and we expect to do so again in the future to lock in a range of pricing for a significant portion or all of our production during the periods covered by the hedges.

ITEM 3. PROPERTIES.

Drilling Activity. As of December 31, 2010 we had drilled and completed 52 gross wells, which is 45.03 net wells that were online for the sale of production as shown in the following table. All of the wells we drilled were “development wells,” which means a well drilled within the proved area of an oil or gas reservoir to the depth of a stratigraphic horizon known to be productive. In addition to the wells we drilled during 2010, our participants’ share of our estimated drilling and equipment costs of 68 gross wells, which is 67.11 net wells, were prepaid by us in 2010 for wells to be drilled in 2011. The drilling of each of the wells we prepaid in 2010 began on or before March 31, 2011, and was not delayed by any shortages of drilling rigs, equipment, supplies or personnel. Those prepaid wells are not included in the following table.

	Development Wells
	Productive (1)				Dry (2)
	Gross (3)		Net (4)		Gross (3)		Net (4)
Period Ending December 31, 2010		52.00		45.03		7.00		6.55

(1)	A “productive well” generally means a well that is not a dry hole.
(2)	A “dry hole” generally means a well found to be incapable of producing either oil or natural gas in sufficient quantities to justify completion as an oil or natural gas well. The term “completion” refers to the installation of permanent equipment for the production of oil or natural gas or, in the case of a dry hole, to the reporting of abandonment to the appropriate agency.
(3)	A “gross” well is a well in which we own a working interest.
(4)	A “net” well equals the actual working interest we own in one gross well divided by one hundred. For example, a 50% working interest in a well is one gross well, but a .50 net well.

Summary of Productive Wells. The table below shows the location by state and the number of productive gross and net wells in which we owned a working interest at December 31, 2010. All of our wells are classified as natural gas wells.

Location	Gross		Net
Colorado		6		6.00
Indiana		41		34.26
Michigan		5		4.77
Total		52		45.03

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

	Production				Average Sales Price
Period from First									Average Production
Production to December			Gas						Cost (Lifting Cost)
31, 2010	Oil (bbls)		(mcf)		per bbl		per mcf (1)		per mcfe (1)(2)
		—		457,100	$	—	$	4.72	$	2.19

34

(1)	“Mcf” means one thousand cubic feet of natural gas. “Mcfe” means one thousand cubic feet equivalent.
	“Bbl” means one barrel of oil. Oil production is converted to mcfe at the rate of six mcf per barrel (“bbl”).
(2)	Production costs include labor to operate the wells and related equipment, repairs and maintenance, materials and supplies, property taxes, severance taxes, insurance, gathering charges and production overhead.

Natural Gas and Oil Reserve Information. As of December 31, 2010 we had drilled and completed for the sale of production 45.03 net wells. Under current conditions, our managing general partner is reasonably certain that the proved reserves as shown in the table below will be produced over the life of our wells. All of the wells we drilled were “development wells,” which means a well drilled within the proved area of an oil or gas reservoir to the depth of a stratigraphic horizon known to be productive. In addition to the wells we drilled during 2010, our participants’ share of our estimated drilling and equipment costs of approximately 67.11 net wells were prepaid by us in 2010. The drilling of each of the wells we prepaid in 2010 began on or before March 31, 2011, and those prepaid wells are not included in the table below. Thus, the reserve information set forth below is not representative of our reserves after all of our wells are drilled and completed. All of our reserves are located in the United States, and the primary areas where our wells are situated are the Marcellus Shale geological formation in Pennsylvania, the New Albany Shale in Indiana, the Niobrara reservoir in Colorado and the Antrim Shale in Michigan. The basic information required for reserve estimation on our proved natural gas and oil reserves was provided by our managing general partner and verified for reasonableness by Wright & Company, Inc., independent energy consultants, in accordance with SEC guidelines.

Reserve estimates are imprecise and may change as additional information becomes available. Furthermore, estimates of natural gas and oil reserves, of necessity, are projections based on engineering and other data. There are inherent uncertainties in the interpretation of this data as well as the projection of future rates of production and the timing of development expenditures. 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.

The price of the estimated future production was calculated as the 12-month unweighted arithmetic average price based on the first-day-of-the-month price for each month within the prior 12-month period, which was $4.38 per million British thermal units (MMBtu) for natural gas. In arriving at the estimated future cash flows, operating costs, development costs, and production-related and ad valorem taxes when applicable. Future prices received from the sale of natural gas may be different from those we estimated. The amounts and timing of future operating, development and abandonment costs may also differ from those used. Thus, the reserves set forth in the following table ultimately may not be produced and the proved reserves may not be produced within the periods anticipated. You should not construe the estimated PV-10 values as representative of the fair market value of our proved natural gas 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 and capital costs. The meaningfulness of these estimates depends on the accuracy of the assumptions on which they were based.

35

The following table summarizes information regarding our estimated proved natural gas and oil reserves as of the date indicated.

	December 31, 2010
Natural gas reserves — Proved Reserves (Mcf)(1)(4):
Total proved reserves of natural gas		24,651,600
Oil reserves — Proved Reserves (Bbl)(1)(4)
Total proved reserves of oil		0
Total proved reserves (Mcfe)		24,651,600
PV-10 estimate of cash flows of proved reserves (3)(4):
Total PV-10 estimate	$	25,239,900

(1)	“Proved Reserves” generally means those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible, from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations, prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.
(2)	“Developed reserves” generally means reserves of any category that can be expected to be recovered through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well.
(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 Rule 4-10 of SEC Regulation S-X for complete definitions of each reserve category, including undeveloped reserves.

We have not filed any estimates of our natural gas and oil reserves with, nor were the estimates included in any reports to, any Federal or foreign governmental agency within the 12 months before the date of this filing. For additional information concerning our natural gas reserves and activities, see Item 13 “Financial Statements and Supplementary Data — Notes to Financial Statements,” beginning on page 70.

Title to Properties. We believe that we hold good and indefeasible title or operating rights to our properties in accordance with standards generally accepted in the natural gas and oil 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 and oil industry, we conduct only a perfunctory title examination at the time we acquire a property. Before we begin drilling operations, however, we conduct an extensive title examination and perform curative work on any defects that we deem significant. We have obtained title examinations for substantially all of our managed producing properties. No single property represents a material portion of our holdings.

36

Our properties are subject to royalty, overriding royalty and other outstanding interests in favor of third-parties customary in the industry, such as free gas to the landowner-lessor for home heating requirements, etc. 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 the estimated acres of developed and undeveloped natural gas and oil acreage in which we have an interest, separated by state, at December 31, 2010.

	Developed Acreage				Undeveloped Acreage (3)
Location	Gross (1)		Net (2)		Gross (1)		Net (2)
Pennsylvania		13.27		13.27		—		—
Indiana		9,120.00		7,995.20		1,280		1,222.40
Michigan		560.00		542.40		160		160.00
Colorado		1,720.00		1,720.00		—		—
Total		11,413.27		10,270.87		1,440		1,382.40

(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 .50 net acre.
(3)	“Undeveloped acreage” means those lease acres on which wells have not been drilled or completed to a point that would permit the production of commercial quantities of natural gas and oil regardless of whether or not the acreage contains proved reserves.

ITEM 5. DIRECTORS AND EXECUTIVE OFFICERS

Managing General Partner. We have no officers, directors or employees. Instead, Atlas Resources, LLC, a Pennsylvania limited liability company, serves as our managing general partner and it intends to allocate its management time, services and other functions on an as-needed basis consistent with its fiduciary duties among us and its other activities, such as the 60 other partnerships in which it currently serves as sponsor or managing general partner, oil and gas lease acquisition activities, and wells it participates in drilling for its own account or the account of its other affiliates, if any, so that our administration as a partnership and our natural gas and oil operations are managed properly. This creates a continuing conflict of interest in allocating management time, services, and other

38

activities among us and our managing general partner’s other activities. If our managing general partner does not devote the necessary time to our management, there could be delays in providing timely annual and semi-annual reports, tax information and cash distributions to our participants. Also, if our managing general partner, serving as the operator of our wells, does not supervise the wells closely enough, for example, there is a risk that there could be delays in undertaking remedial operations on a well, if necessary to increase the production of natural gas from the well.

Our managing general partner’s indirect parent company is Atlas Energy, L.P. (NYSE: ATLS) (“Atlas Energy”). Our managing general partner depends on Atlas Energy and its affiliates for all management and administrative functions and financing for capital expenditures. Atlas Energy and its affiliates employ more than 375 persons. Atlas Energy, formerly known as Atlas Pipeline Holdings, L.P. as discussed below, is a publicly-traded Delaware limited partnership. Atlas Energy’s general partner is Atlas Energy GP, LLC. Atlas Energy’s wholly-owned subsidiary, Atlas Pipeline Partners GP, LLC (“Atlas Pipeline GP”), a Delaware limited liability company, is the general partner of Atlas Pipeline Partners, L.P., a publicly-traded Delaware limited partnership (NYSE: APL).

Atlas Energy is headquartered at Westpointe Corporate Center One, 1550 Coraopolis Heights Road, Suite 300, Moon Township, Pennsylvania 15108, near the Pittsburgh International Airport, which is also our managing general partner’s primary office. Since 1985 our managing general partner has sponsored 22 public and 38 private partnerships to conduct natural gas drilling and development activities. Currently, our managing general partner and its affiliates operate more than 8,000 natural gas and oil wells located primarily in the Appalachian Basin.

On February 17, 2011, Atlas Energy completed the transactions, which we refer to as the “Asset Acquisition,” contemplated by Atlas Energy’s transaction agreement (the “Atlas Energy Transaction Agreement”), dated November 8, 2010, with Atlas Energy, Inc. and Atlas Energy Resources, LLC (“ATN”), a wholly-owned subsidiary of Atlas Energy, Inc., which are former indirect parent companies of our managing general partner, pursuant to which Atlas Energy purchased from Atlas Energy, Inc.: (1) its investment partnership business, including the operations of its investment partnerships, including us, in Michigan, Pennsylvania, Tennessee, Indiana and Colorado; (2) its oil and gas exploration, development and production activities conducted in Tennessee, Indiana and Colorado, certain shallow wells and leases in New York and Ohio and certain well interests in Pennsylvania; and (3) its ownership and management of investments in Lightfoot Capital Partners, L.P. and related entities. The assets Atlas Energy purchased included certain Atlas Energy, Inc. subsidiaries. In connection with the Asset Acquisition, Atlas Energy, Inc. contributed Atlas Energy’s general partner, Atlas Energy GP, LLC to Atlas Energy, and Atlas Energy GP, LLC became Atlas Energy’s wholly-owned subsidiary. All of these transactions, along with the Asset Acquisition are referred to collectively as the “Atlas Energy Transactions.”

39

Concurrently with Atlas Energy’s completion of the Asset Acquisition, APL completed its sale to ATN of its 49% non-controlling interest in Laurel Mountain Midstream, LLC (the “Laurel Mountain Sale”) for $413.5 million in cash, including adjustments based on certain capital contributions APL made to and distributions it received from Laurel Mountain after January 1, 2011. APL retained the preferred distribution rights under the limited liability company agreement of Laurel Mountain entitling APL Laurel Mountain LLC to receive all payments made under a note issued to Laurel Mountain by Williams Laurel Mountain, LLC in connection with the formation of Laurel Mountain.

Concurrently with Atlas Energy’s completion of the Asset Acquisition and APL’s completion of the Laurel Mountain Sale, Atlas Energy, Inc. completed its merger transaction with Chevron Corporation (“Chevron”), pursuant to which, among other things, Atlas Energy, Inc. became a wholly-owned subsidiary of Chevron (the “Chevron Merger”). The APL common Units and 12% cumulative Class C preferred Units held directly by Atlas Energy, Inc. were acquired by Chevron as part of the Chevron Merger.

As a result of the Atlas Energy Transactions, our managing general partner became an indirect subsidiary of Atlas Energy, L.P. and was no longer affiliated with Atlas Energy, Inc. or Laurel Mountain Midstream, LLC, nor was it an affiliate of Chevron. Further, the Atlas Energy Transactions did not have any effect on our business or assets, expect as described below:

• Atlas Energy, Inc., Atlas Energy and our managing general partner, entered into a Pennsylvania Operating Services Agreement, dated as of February 17, 2011 (the “Pennsylvania Operating Agreement”), pursuant to which Atlas Energy, Inc. will provide Atlas Energy and our managing general partner and their respective subsidiaries, including drilling partnerships managed by subsidiaries of Atlas Energy, which includes us, certain operational services including, among others, gas volumetric control, measurement and balancing services and water disposal services with respect to certain wells in Pennsylvania (the “Pennsylvania Services”) in exchange for specified fees. Atlas Energy will indemnify Atlas Energy, Inc. against all claims and liabilities arising out of its provision of services under the Pennsylvania Operating Agreement.

Atlas Energy, Inc. will provide the Pennsylvania Services for three years from February 17, 2011, and from month-to-month thereafter until cancelled by either Atlas Energy, Inc., Atlas Energy or our managing general partner. Atlas Energy may terminate the Pennsylvania Services or terminate the Pennsylvania Operating Agreement at any time. Atlas Energy, Inc., Atlas Energy and our managing general partner may agree to terminate the Pennsylvania Operating Agreement at any time, and each of Atlas Energy, Inc., on the one hand, or Atlas Energy or our managing general partner, on the other hand, may terminate the Pennsylvania Operating Agreement following an uncured material breach by such other party.

40

• Atlas Energy, Inc. and Atlas Energy entered into a Petro-Technical Services Agreement, dated as of February 17, 2011 (the “Petro-Technical Services Agreement”), pursuant to which Atlas Energy, Inc. will perform for Atlas Energy certain consulting services including, among others, planning, designing, drilling, stimulating, completing and equipping wells (the “Petro-Technical Services”). Atlas Energy will be obligated to pay the actual costs incurred by Atlas Energy, Inc. in the performance of the Petro-Technical Services, up to a maximum of the market rate for the same or similar services in Pittsburgh, Pennsylvania or Traverse City, Michigan, depending on the location of the well. Atlas Energy will indemnify Atlas Energy, Inc. against all claims and liabilities arising out of its provision of services under the Petro-Technical Services Agreement. Atlas Energy, Inc. will provide the Petro-Technical Services for one year from February 17, 2011 and from month-to-month thereafter until the earlier of (1) cancellation by Atlas Energy, Inc., Atlas Energy or our managing general partner or (2) eighteen months after February 17, 2011. Atlas Energy may terminate the Petro-Technical Services Agreement at any time. Atlas Energy, Inc., Atlas Energy and our managing general partner may agree to terminate the Petro-Technical Services Agreement at any time, and each of Atlas Energy, Inc., on the one hand, or Atlas Energy or our managing general partner, on the other hand, may terminate the Petro-Technical Services Agreement following an uncured material breach by such other party.

• Viking Resources, LLC (“Viking”) and Resource Energy, LLC (“Resource Energy” and, together with our managing general partner and Viking, the “Gas Marketing Parties”), entered into a Base Contract for the Sale and Purchase of Natural Gas with Chevron Natural Gas, a division of Chevron USA Inc. (“Chevron Natural Gas”), dated as of November 8, 2010 (the “Gas Marketing Agreement”). Each of our managing general partner, Viking and Resource Energy were subsidiaries of Atlas Energy, Inc. at the time the Gas Marketing Agreement was entered into and were sold to Atlas Energy pursuant to the Transaction Agreement. Pursuant to the Gas Marketing Agreement, the Gas Marketing Parties will sell gas to Chevron Natural Gas. Under the Gas Marketing Agreement, the Gas Marketing Parties are responsible for transporting the gas to specified delivery points in southwest Pennsylvania, at which points Chevron Natural Gas will assume responsibility for the purchased gas. The Gas Marketing Agreement will terminate upon the expiration of the latest period for which the parties have agreed to make deliveries or upon 30 days’ written notice of any party to the Gas Marketing Agreement.

41

At March 31, 2011, Atlas Energy had a credit facility with a syndicate of banks that matures in March 2016. The maximum lender commitments under the credit facility are $300 million, with an initial borrowing base of $125 million. As of March 31, 2011, Atlas Energy had no outstanding borrowings under the credit facility. The borrowing base under the credit agreement will be redetermined semi-annually, with the first such redetermination to occur on May 1, 2011. Atlas Energy and the administrative agent, at the direction of the super majority lenders (as defined in the credit agreement), each also have the right to initiate one interim redetermination during each six month period, and Atlas Energy may further initiate an interim redetermination in connection with specified transactions including the acquisition of oil and gas properties with values above a threshold specified in the credit agreement. In connection with each redetermination of the borrowing base, the administrative agent will propose a new borrowing base based upon, among other things, reserve reports and such other information as the administrative agent deems appropriate in its reasonable discretion and consistent with its normal oil and gas lending criteria as they exist at the particular time. The borrowing base is automatically reduced by 25% of the stated principal of any senior unsecured notes issued by Atlas Energy. Up to $50 million of the credit facility may be in the form of standby letters of credit, of which no amount was outstanding at March 31, 2011. The facility is secured by substantially all of Atlas Energy’s assets and is guaranteed by each of its material subsidiaries. This includes a guaranty by our managing general partner and a pledge of our managing general partner’s interests in its partnerships, including our managing general partner’s interest in us, but does not include our participants’ Units in us. At Atlas Energy’s election, interest on borrowings under the credit facility is determined by reference to either LIBOR plus an applicable margin between 2.00% and 3.25% per annum or the base rate (which is the higher of the Wells Fargo prime rate, the Federal funds rate plus 0.5% or one-month LIBOR plus 1.00%) plus an applicable margin between 1.00% and 2.25% per annum. These margins will fluctuate based on the utilization of the facility.

The events which constitute an event of default for Atlas Energy’s credit facility are customary for loans of this size, including payment defaults, breaches of representations or covenants contained in the credit agreement, adverse judgments against Atlas Energy in excess of a specified amount and a change of control. In addition, the agreement limits sales, leases or transfers of assets and the incurrence of additional indebtedness. Atlas Energy was in compliance with these covenants as of March 31, 2011. The credit facility also requires Atlas Energy to maintain a ratio of current assets (as defined in the credit facility) to current liabilities (as defined in the credit facility) of not less than 1.0 to 1.0, a ratio of total funded debt (as defined in the credit facility) to earnings before interest, taxes, depreciation, depletion and amortization (“EBITDA”, as defined in the credit facility) of not more than 3.75 to 1.0, and a ratio of EBITDA to consolidated interest expense (as defined in the credit facility) of not less than 2.5 to 1.0.

42

If Atlas Energy were to default under its credit facility, the lenders could proceed against the collateral granted to them to secure that indebtedness and if they accelerate the repayment of the borrowings, Atlas Energy may not have sufficient assets to repay its credit facility and its other indebtedness. In that event, the lenders could seek to recover the amounts owed under Atlas Energy’s credit facility from the managing general partner pursuant to the managing general partner’s guarantee or pledge of its assets as collateral for the credit facility as discussed above, which could adversely affect the managing general partner’s ability to meet its financial commitments to us. See Item 1A “Risk Factors — Risks Related to Our Business — Natural Gas Prices are Volatile and a Substantial Decrease in Prices, Particularly Natural Gas Prices, Would Decrease Our Revenues, Our Cash Distributions and the Value of Our Properties and Could Reduce Our Managing General Partner’s Ability to Loan Us Funds; Meet Its Ongoing Obligations to Indemnify Our Investor General Partners and Purchase Units Under Our Presentment Feature,” on page 13 and the related discussion of Atlas Energy’s credit facility on page 14. Also, Atlas Energy’s borrowings under its credit facility are, and are expected to continue to be, at variable rates of interest and expose it to interest rate risk. If interest rates increase, Atlas Energy’s debt service obligations on the variable rate indebtedness would increase even though the amount borrowed remained the same, and its net income would decrease.

• the requirement that property transactions between us and our managing general partner must be fair and reasonable;

• repayment of borrowings;

• cost overruns;

• remedial work to improve a well’s producing capability, including additional fracs in the Marcellus Shale;

• direct costs and our general and administrative expenses;

• reserves, including a reserve for the estimated costs of eventually plugging and abandoning our wells; or

• indemnification of our managing general partner and its affiliates for losses or liabilities incurred in connection with our activities.

The determination of our revenues and costs will be made in accordance with generally accepted accounting principles, consistently applied. During the period ended December 31, 2010, we did not pay any cash distributions to our managing general partner or our participants. During the period ended March 31, 2011, we distributed $367,700 to our participants and $187,300 to our managing general partner.

ITEM 10. RECENT SALES OF UNREGISTERED SECURITIES.

We sold 7,500 Units to 2,273 investors in a private placement offering of our Units beginning April 19, 2010 and ending September 20, 2010. Anthem Securities, Inc., an affiliate of our managing general partner, served as the dealer-manager of the offering and received the compensation set forth in Item 7 “Certain Relationships and Related Transactions — Dealer-Manager Fees” on page 58. Our net proceeds from the sale of our Units were $149,724,600.

We relied on the exemption from registration provided by Rule 506 under Regulation D and Section 4(2) of the Securities Act in connection with the offering. Our Units were offered and sold to a limited number of persons who had the sophistication to understand the merits and risks of the investment, who had the financial ability to bear those risks, and who were “accredited investors,” as that term is defined in Regulation D (17 CFR 230.501(a)). All of our participants were reasonably believed by our managing general partner to be accredited investors at the time of sale.

ITEM 11. DESCRIPTION OF REGISTRANT’S SECURITIES TO BE REGISTERED.

General. The rights and obligations of the holders of our Units (i.e., our participants) are governed by our partnership agreement. “Units” means limited partner Units, investor general partner Units and the converted limited partner Units into which the investor general partner Units will be automatically converted by our managing general partner after all of our wells have been drilled and completed. We were formed under the Delaware Revised Uniform Limited Partnership Act and are qualified to transact business in the jurisdictions where our wells are located. The following discussion is a summary of the material provisions of our partnership agreement that are not described elsewhere in this registration statement.

General Powers of Our Managing General Partner. Our managing general partner, Atlas Resources, LLC has exclusive management control over all aspects of our business, including generally the following power to:

• determine which leases are developed or abandoned;

• negotiate and execute any contracts or other instruments on our behalf, including the drilling and operating agreement;

• enter into hedging agreements on our behalf with respect to our natural gas and oil production;

• select both affiliated and third-party consultants and contractors and the determine their compensation and other terms of employment or hiring, which compensation may not exceed competitive rates with respect to affiliates of our managing general partner;

• obtain and maintain insurance for our benefit as it deems necessary;

• use our subscription proceeds and revenues, on any terms it sees fit, for the conduct or financing, in whole or in part, of our drilling and other activities; and

• sell, exchange, release or abandon any or all of our assets, including without limitation, leases, wells, equipment and production therefrom, provided that the sale of all or substantially all of our assets shall only be made with the consent of our participants who own a majority of our outstanding Units.

Indemnification of Our Managing General Partner. The partnership agreement provides for indemnification of our managing general partner, the operator, and their affiliates by us against any losses, judgments, liabilities, expenses, and amounts paid in settlement of any claims sustained by them in connection with us provided that:

• they determined in good faith that the course of conduct was in our best interest;

• they were acting on behalf of, or performing services for us; and

• their course of conduct did not constitute negligence or misconduct.

See Item 12 “Indemnification of Directors and Officers” beginning on page 69 for a more detailed discussion.

60

Liability of Participants for Further Calls and Conversion. We are governed by the Delaware Revised Uniform Limited Partnership Act. If a participant invested in us as a limited partner, then generally the participant will not be liable to third-parties for our obligations unless the participant:

• also invested in us as an investor general partner;

• takes part in the control of our business in addition to the exercise of a participant’s rights and powers as a limited partner; or

• fails to make a required capital contribution to the extent of the required capital contribution, which is not required, however, unless the limited partner also invests as an investor general partner and we incur a liability for which the limited partner’s allocable share exceeds his or her pro rata portion of our undistributed assets and insurance proceeds, if any, and our managing general partner’s indemnification of the investor general partners for such liabilities as discussed below.

In addition, a limited partner participant may be required to return any distribution received if the participant knew at the time the distribution was made that it was improper because it rendered us insolvent.

If the participant invested in us as an investor general partner for the tax benefits instead of as a limited partner, then his Units will be automatically converted by our managing general partner to limited partner Units after all of our wells have been drilled and completed. See Item 1 “Business” beginning on page 1. Currently, the conversion has not occurred, because we have not yet drilled and completed all of our wells.

After the investor general partner Units are converted to limited partner Units, which is a nontaxable event, the participant will have the lesser liability of a limited partner under Delaware law for our obligations and liabilities that arise after the conversion, subject to the exceptions described above. However, an investor general partner will continue to have the responsibilities of a general partner for liabilities and obligations that we incurred before the effective date of the conversion. For example, an investor general partner might become liable for any liabilities we incurred in excess of his subscription amount during the time we engaged in drilling activities and for environmental claims that arose during drilling activities, but were not discovered until after conversion. This could result in the former investor general partner being required to make payments, in addition to his original investment, in amounts that are impossible to predict because of their uncertain nature.

Distributions and Subordination. Our managing general partner will review our accounts at least monthly to determine whether cash distributions are appropriate and the amount to be distributed, if any. Subject to our managing general partner’s subordination obligation as described below, our managing general partner and our participants share in all of our production revenues in the same percentage as their respective capital contribution bears to our total capital contributions, except that our managing general partner receives an additional 10% of our natural gas and oil revenues. As of December 31, 2010, our managing general partner received 33.75% of our production revenues and our participants received 66.25% of our production revenues. Subject to the foregoing, these sharing percentages will be adjusted based on the final amount of our managing general partner’s capital contributions to us after all of our wells have been drilled and completed. See our partnership agreement for special allocations between our managing general partner and our participants of equipment proceeds, lease proceeds and interest income.

61

Our partnership agreement is structured to provide our participants with cash distributions equal to at least 12% of capital ($2,400 per $20,000 unit) in the first 12-month subordination period, 10% of capital ($2,000 per $20,000 unit) in each of the next three 12-month subordination periods, and 8% of capital ($1,600 per $20,000 unit) in the fifth 12-month subordination period, based on a subscription price of $20,000 per Unit regardless of the actual subscription price paid by any participant for a Unit, beginning when our managing general partner determines that natural gas or oil is being sold from at least 75% of our wells, excluding any wells drilled that were nonproductive. To help achieve this investment feature, under our partnership agreement our managing general partner will subordinate up to 50% of its share of our partnership net production revenues during this subordination period. The term “partnership net production revenues” means our gross revenues from the sale of our natural gas and oil production from our wells after deduction of the related operating costs, direct costs, administrative costs, and all other costs not specifically allocated in the partnership agreement. However, if our wells produce only small natural gas and oil volumes, and/or natural gas and oil prices decrease, then even with subordination a participant may not receive the return of capital for each of the first five years as described above, or a return of all of his capital during our term, because the subordination is not a guarantee.

Subordination distributions will be determined by debiting or crediting our current period revenues to our managing general partner as may be necessary to provide the distributions to our participants. At any time during the 60- month aggregate subordination period our managing general partner is entitled to an additional share of our revenues to recoup previous subordination distributions to the extent cash distributions from us to our participants would exceed the return of capital described above. The specific formula is set forth in Section 5.01(b)(4)(a) of our partnership agreement.

Participant Allocations. Our participants’ share as a group of our revenues, gains, income, costs, expenses, losses, and other charges and liabilities generally are charged and credited among our participants in accordance with their respective number of Units, based on $20,000 per Unit regardless of the actual subscription price paid by any participant for a Unit. These allocations also take into account any investor general partner’s status as a defaulting investor general partner.

Certain participants, however, paid a reduced amount to acquire their Units. Thus, our intangible drilling costs and our participants’ share of our equipment costs to drill and complete our wells are charged among our participants in accordance with the respective subscription price they paid for their Units, rather than their respective number of Units.

Term, Dissolution and Distributions on Liquidation. We will continue in existence for 50 years unless we are terminated earlier by a final terminating event as described below, or by an event which causes the dissolution of a limited partnership under the Delaware Revised Uniform Limited Partnership Act. However, if an event which causes our dissolution under state law is not a final terminating event, then a successor limited partnership will automatically be formed. Thus, only on a final terminating event will we be liquidated. A final terminating event is any of the following:

• the election to terminate us by our managing general partner or the affirmative vote of our participants whose Units equal a majority of our total Units;

• our termination under Section 708(b)(1)(A) of the Internal Revenue Code because no part of our business is being carried on; or

• we cease to be a going concern.

62

On our liquidation a participant will receive his capital interest in us. Generally, this means an undivided interest in our assets, after payments to our creditors, in the ratio the participant’s capital account bears to all of the capital accounts in us until all capital accounts have been reduced to zero. Thereafter, the participant’s capital interest in our remaining assets will equal the participant’s interest in our related revenues.

Any in-kind property distributions to a participant from us must be made to a liquidating trust or similar entity, unless the participant affirmatively consents to receive an in-kind property distribution after being told the risks associated with the direct ownership of our natural gas and oil properties or there are alternative arrangements in place which assure that the participant will not be responsible for the operation or disposition of our natural gas and oil properties. If our managing general partner has not received a participant’s written consent to the in-kind distribution within 30 days after it is mailed, then it will be presumed that the participant did not consent. Our managing general partner may then sell the asset at the best price reasonably obtainable from an independent third-party, or to itself or its affiliates at fair market value as determined by an independent expert selected by our managing general partner. Also, if we are liquidated our managing general partner will be repaid for any debts owed it by us before there are any distributions to our participants.

Transferability. Our Units may not be sold, assigned or otherwise transferred unless certain conditions set forth in our partnership agreement are satisfied, including:

• an opinion of counsel acceptable to our managing general partner that the transfer of the Unit does not require registration and qualification under the Securities Act of 1933 and applicable state securities laws, unless this requirement is waived by our managing general partner; and

• a determination under the tax laws that a transfer of the Unit would not, in the opinion of our counsel, result in our termination for tax purposes or our being treated as a “publicly-traded” partnership for tax purposes.

Also, under the partnership agreement transfers are subject to the following limitations:

• except as provided by operation of law, we will recognize the transfer of only one or more whole Units unless the participant making the transfer owns less than a whole Unit, in which case the entire fractional interest in the Unit must be transferred;

• the costs and expenses associated with the transfer must be paid by the participant transferring the Unit;

• the form of transfer must be in a form satisfactory to our managing general partner; and

• the terms of the transfer must not contravene those of our partnership agreement.

A transfer of a participant’s Unit will not relieve the participant of responsibility for any obligations related to his Unit under the partnership agreement. Also, the transfer of a Unit does not grant rights under the partnership agreement, as among the transferees, to more than one party unanimously designated by the transferees to our managing general partner. Further, the transfer of a Unit does not require an accounting by our managing general partner.

63

Finally, a sale of a participant’s Units could create adverse tax and economic consequences for the participant. The sale or exchange of Units held for more than 12 months generally will result in recognition of long-term capital gain or loss. However, previous deductions by the participant for depreciation, depletion and intangible drilling costs may be recaptured as ordinary income rather than capital gain, regardless of how long the participant owned the Units. If the Units are held for 12 months or less, then the gain or loss generally will be short-term gain or loss. The participant’s pro rata share of our liabilities, if any, as of the date of the sale or exchange must be included in the amount realized by the participant. Thus, the gain recognized by the participant may result in a tax liability greater than the cash proceeds, if any, received by the participant from the sale or other taxable disposition of his Units.

Under our partnership agreement, an assignee (transferee) of a Unit may become a substituted partner only on meeting certain further conditions. The conditions to become a substituted partner are as follows:

• the assignor (transferor) gives the assignee the right;

• our managing general partner consents to the substitution;

• the assignee pays all costs and expenses incurred in connection with the substitution; and

• the assignee executes and delivers, in a form acceptable to our managing general partner, the instruments necessary to establish that a legal transfer has taken place and to confirm his or her agreement to be bound by all terms and provisions of the partnership agreement.

A substituted partner is entitled to all of the rights of full ownership of the assigned Units, including the right to vote. We will amend our records at least once each calendar quarter to effect the substitution of substituted partners.

Presentment Feature. Beginning in 2015 a participant may present his Units to our managing general partner for purchase. However, a participant is not required to offer his Units to our managing general partner, and may receive a greater return if the Units are retained.

Our managing general partner has no obligation to establish a reserve to satisfy the presentment obligation, and it does not intend to do so. Our managing general partner may immediately suspend its purchase obligation by notice to our participants if it determines, in its sole discretion, that it does not have the necessary cash flow or cannot arrange financing or other consideration for this purpose on terms it deems reasonable.

Our managing general partner will not purchase less than one Unit unless the fractional Unit represents the participant’s entire interest in us, nor more than 5% of our total Units in any calendar year. If fewer than all of the Units presented at any time are to be purchased, then the Units to be purchased will be selected by lot. Our managing general partner may not waive the limit on its purchasing more than 5% of our total Units in any calendar year.

Our managing general partner’s obligation to purchase the Units presented by our participants may be discharged for its benefit by a third-party or an affiliate of our managing general partner. The Unit will be transferred to the party who pays for it, along with the delivery of an executed assignment. The presentment must be within 120 days of our reserve report discussed below and, in accordance with Treas. Reg. §1.7704-1(f), the purchase may not be made by our managing general partner until at least 60 calendar days after written notice of the participant’s intent to present the Unit was made.

64

The amount of the presentment price will be the greater of the following amounts:

• three times the amount of our total distributions to a participant during the previous twelve months; or

• the amount that is generally attributable to the participant’s share of our natural gas and oil reserves, as discussed below.

The amount of the presentment price attributable to our natural gas and oil reserves will be determined based on our last reserve report. Beginning in 2012, and every year thereafter, our managing general partner will prepare an annual reserve report of our natural gas and oil proved reserves which will be reviewed by an independent expert. The presentment price to a participant will be based on his share of our net assets and liabilities as described below, based on the ratio that his number of Units bears to the total number of our Units. The presentment price will include the participant’s share of the sum of the following partnership items:

• an amount based on 70% of the present worth of future net revenues from our proved reserves as described our most recent reserve report as described above;

• cash on hand;

• prepaid expenses and accounts receivable, less a reasonable amount for doubtful accounts; and

• the estimated market value of all assets not separately specified above, determined in accordance with standard industry valuation procedures.

There will be deducted from the foregoing sum the following items:

• an amount equal to the participant’s share of all debts, obligations, and other liabilities, including accrued expenses; and

• any distributions made to the participant between the date of the request and the actual payment. However, if any cash distributed was derived from the sale, after the presentment request, of oil, natural gas, or a producing property, for purposes of determining the reduction of the presentment price the distributions will be discounted at the same rate used to take into account the risk factors employed to determine the present worth of our proved reserves.

The amount may be further adjusted by our managing general partner for estimated changes from the date of the reserve report to the date of payment of the presentment price because of various considerations described in our partnership agreement.

65

Voting Rights and Amendments. Other than as set forth below, a participant generally will not be entitled to vote on any of our partnership matters at any meeting. However, at any time participants whose Units equal 10% or more of our total Units may call a meeting to vote, or vote without a meeting, on the matters set forth below without the concurrence of our managing general partner. On the matters being voted on a participant is entitled to one vote per Unit or, if the participant owns a fractional Unit, that fraction of one vote equal to the fractional interest in the Unit. Participants whose Units equal a majority of our total Units may vote to:

• dissolve us;

• remove our managing general partner and elect a new managing general partner;

• elect a new managing general partner if our managing general partner elects to withdraw from the partnership;

• remove the operator and elect a new operator;

• approve or disapprove the sale of all or substantially all of our assets;

• cancel any contract for services with our managing general partner, the operator, or their affiliates, which is not otherwise described in the private placement memorandum for the offering of our Units or our partnership agreement without penalty on 60 days notice; and

• amend our partnership agreement; provided however, any amendment may not:

• without the approval of our participants or our managing general partner, increase the duties or liabilities of the participants or our managing general partner or increase or decrease the profits or losses or required capital contribution of our participants or our managing general partner; or

• without the unanimous approval of our participants, affect the classification of our income and loss for federal income tax purposes.

Although our managing general partner and its officers, directors, and affiliates could have voted on certain issues as a participant if they had purchased Units, they did not purchase any Units. In addition to amendments by our participants as described above, amendments to our partnership agreement may be proposed in writing by our managing general partner and adopted with the consent of participants whose Units equal a majority of our total Units. Our partnership agreement may also be amended by our managing general partner without the consent of our participants for certain limited purposes set forth in our partnership agreement.

Books and Records. Our managing general partner is required to keep books and records of all of our financial activities in accordance with generally accepted accounting principles. A participant may inspect and copy any of the records, including a list of our participants subject to the conditions described below, at any reasonable time after giving adequate notice to our managing general partner. Access to the list of our participants is subject to the following conditions:

• an alphabetical list of the names, addresses, and business telephone numbers of our participants along with the number of Units held by each of them (the “Participant List”) must be maintained as a part of our books and records and be available for inspection by any participant or his designated agent at our home office on the participant’s request;

• the Participant List must be updated at least quarterly to reflect changes in the information contained in the Participant List;

• a copy of the Participant List must be mailed to any participant requesting the Participant List within 10 days of the written request;

66

• the purposes for which a participant may request a copy of the Participant List include, without limitation, matters relating to the participant’s voting rights under our partnership agreement and the exercise of participant’s rights under the federal proxy laws; and

• our managing general partner may refuse to exhibit, produce, or mail a copy of the Participant List as requested if our managing general partner believes that the actual purpose and reason for the request for inspection or for a copy of the Participant List is to secure the list or other information for the purpose of selling the list or information or copies of the list, or of using the same for a commercial purpose other than in the interest of the applicant as a participant relative to our affairs. Our managing general partner will require the participant requesting the Participant List to represent in writing that the list was not requested for a commercial purpose unrelated to the participant’s interest in us.

Also, our managing general partner may keep logs, well reports, and other drilling and operating data confidential for reasonable periods of time.

Restrictions on Roll-Up Transactions. In connection with any proposed transaction which is considered a “Roll-up Transaction” involving us and the issuance of securities of an entity (a “Roll-up Entity”) that would be created or would survive after the successful completion of the Roll-up Transaction, an appraisal of all of our natural gas and oil properties must be obtained from a competent independent appraiser. Our properties must be appraised on a consistent basis, and the appraisal must be based on the evaluation of all relevant information and must indicate the value of our properties as of a date immediately before the announcement of the proposed Roll-up Transaction. The appraisal must assume an orderly liquidation of our properties over a 12-month period. The terms of the engagement of the independent appraiser must clearly state that the engagement is for the benefit of us and our participants. A summary of the appraisal, indicating all of the material assumptions underlying the appraisal, must be included in a report to our participants in connection with the proposed Roll-up Transaction. A “Roll-up Transaction” is transaction involving our acquisition, merger, conversion or consolidation, directly or indirectly, and the issuance of securities of a Roll-up Entity. This term does not include:

• a transaction involving our securities that have been listed on a national securities exchange or included for quotation on Nasdaq National Market System for at least 12 months; or

• a transaction involving only our conversion to corporate, trust, or association form if, as a consequence of the transaction, there will be no significant adverse change in any of the following: voting rights; the term of our existence; compensation to our managing general partner; or our investment objectives.

In connection with a proposed Roll-up Transaction, the person sponsoring the Roll-up Transaction must offer to our participants who vote “no” on the proposal the choice of:

• accepting the securities of the Roll-up Entity offered in the proposed Roll-up Transaction; or

• one of the following:

• remaining as participants in us and preserving their interests in us on the same terms and conditions as existed previously, or

• receiving cash in an amount equal to each participant’s pro rata share of the appraised value of our net assets.

67

We are prohibited from participating in any proposed Roll-Up Transaction:

• which would result in the diminishment of any participant’s voting rights under the Roll-up Entity’s chartering agreement or limit the ability of a participant to exercise the voting rights of its securities of the Roll-up Entity on the basis of the number of our Units held by the participant;

• in which the democracy rights of our participants in the Roll-up Entity would be less than those provided for under §§4.03(c)(1) and 4.03(c)(2) of our partnership agreement or, if the Roll-up Entity is a corporation, then the democracy rights of our participants must correspond to the democracy rights provided for our participants in our partnership agreement to the greatest extent possible;

• which includes provisions that would operate to materially impede or frustrate the accumulation of shares by any purchaser of the securities of the Roll-up Entity, except to the minimum extent necessary to preserve the tax status of the Roll-up Entity;

• in which our participants’ rights of access to the records of the Roll-up Entity would be less than those provided for under §§4.03(b)(5), 4.03(b)(6) and 4.03(b)(7) of our partnership agreement;

• in which any of the costs of the transaction would be borne by us if our participants whose Units equal a majority of our total Units do not vote to approve the proposed Roll-Up Transaction; and

• unless the Roll-up Transaction is approved by our participants whose Units equal a majority of our total Units.

We currently have no plans to enter into a Roll-Up Transaction.

Withdrawal of Managing General Partner. After 10 years our managing general partner may voluntarily withdraw as our managing general partner for whatever reason by giving 120 days’ written notice to our participants. Although our withdrawing managing general partner is not required to provide a substitute managing general partner, a new managing general partner may be substituted by the affirmative vote of our participants whose Units equal a majority of our total Units. If our participants, however, choose to terminate our existence and do not select a substitute managing general partner, then we would terminate and dissolve which could result in adverse tax and other consequences to our participants.

Also, our managing general partner may assign its general partner interest in us to its affiliates and it may withdraw a property interest from us in the form of a working interest in our wells equal to or less than its revenue interest in us without the consent of our participants.

68

Drilling and Operating Agreement. Our managing general partner serves as the operator of all of our wells under the drilling and operating agreement. The following is a summary of the material provisions of the drilling and operating agreement that are not covered elsewhere in this registration statement:

• The operator may be replaced at any time on 60 days’ advance written notice by our managing general partner acting on our behalf on the affirmative vote of investors whose Units equal a majority of our total outstanding Units.

• The operator may resign as operator after five years without our consent.

• The operator has the right, beginning one year after each of our wells begins producing, to retain $200 per month to cover its estimate of our future plugging and abandonment costs of the well.

• The operator has a first lien and security interest in the wells and related production to secure payment of amounts due to the operator by us.

• The operator must obtain and maintain workmens’ compensation insurance as required under applicable state law and comprehensive general public liability insurance of not less than $1 million per person per occurrence for personal injury or death and $1 million for property damage per occurrence, including blow-outs, and total liability coverage of not less than $10 million.

• The operator is not permitted to incur extraordinary costs with respect to producing wells in excess of $5,000 per well, unless necessary to safeguard persons or property or to protect a well if there is a sudden emergency.

• We may not transfer our interest in fewer than all of our wells unless the transfer is of an equal undivided interest in all of the wells.

• The operator will not have any liability for any loss suffered by us or our participants which arises out of any action or inaction of the operator if the operator determined in good faith that the course of conduct was in our best interest, the operator was performing services for us and the operator’s course of conduct did not constitute negligence or misconduct.

Also, nonperformance under the drilling and operating agreement by the operator due to force majeure, which generally means acts of God, catastrophes and other causes which preclude the operator’s performance and are beyond its control, is suspended during the continuance of the force majeure.

ITEM 12. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Under the terms of our partnership agreement, our managing general partner, the operator, and their affiliates have limited their liability to us and our participants for any loss suffered by us or the participants which arises out of any action or inaction on their part if:

• they determined in good faith that the course of conduct was in our best interest;

• they were acting on our behalf or performing services for us; and

• their course of conduct did not constitute negligence or misconduct.

69

In addition, our partnership agreement provides for our indemnification of our managing general partner, the operator, and their affiliates against any losses, judgments, liabilities, expenses, and amounts paid in settlement of any claims sustained by them in connection with us provided that they meet the standards set forth above. However, there is a more restrictive standard for indemnification for losses arising from or out of an alleged violation of federal or state securities laws. Also, to the extent that any indemnification provision in our partnership agreement purports to include indemnification for liabilities arising under the Securities Act of 1933, as amended, in the SEC’s opinion this indemnification is contrary to public policy and therefore unenforceable.

Payments arising from the indemnification or agreement to hold harmless described above are recoverable only out of our tangible net assets, including our revenues, and any insurance proceeds. Still, the use of our funds or assets for indemnification of our managing general partner, the operator or an affiliate would reduce amounts available for our operations or for distribution to our participants.

Under our partnership agreement, we are not allowed to pay the cost of the portion of any insurance that insures our managing general partner, the operator, or an affiliate against any liability for which they cannot be indemnified as described above. However, our funds can be advanced to them for legal expenses and other costs incurred in any legal action for which indemnification is being sought if we have adequate funds available and certain conditions in our partnership agreement are met.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Partners of
Atlas Resources Series #28-2010 L.P.

We have audited the accompanying balance sheet of Atlas Resources Series #28-2010 L.P. (a Delaware Limited Partnership) as of December 31, 2010, and the related statement of operations, comprehensive income, changes in partners’ capital, and cash flows for the period April 1, 2010 (commencement of operations) through December 31, 2010. 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 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 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 audit provides 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 Resources Series #28-2010 L.P. as of December 31, 2010, and the results of its operations and its cash flows for the period April 1, 2010 (commencement of operations) through December 31, 2010 in conformity with accounting principles generally accepted in the United States of America.

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2010

NOTE 1 — DESCRIPTION OF BUSINESS

Atlas Resources Series 28-2010 L.P. (the “Partnership”) is a Delaware limited partnership, which commenced operations on April 1, 2010 and had production begin in June 2010, with Atlas Resources, LLC serving as its Managing General Partner and Operator (Atlas Resources or “MGP”). Atlas Resources, LLC is an indirect subsidiary of Atlas Energy, Inc., (“Atlas Energy”) (NASDAQ: ATLS). Atlas Energy’s focus is on the development and/or production of natural gas and oil in the Appalachian, Michigan, Illinois, and/or Colorado basin regions of the United States of America. Atlas Energy is also a leading sponsor of and manages tax-advantaged direct investment partnerships, in which it co-invests to finance the exploitation and development of its acreage. Atlas Energy Resource Services, Inc. provides Atlas Energy with the personnel necessary to manage its assets and raise capital.

On February 17, 2011, Atlas Pipeline Holdings, L.P. (“AHD”) (NYSE: AHD), a then-majority owned subsidiary of Atlas Energy and general partner to Atlas Pipeline Partners, L.P. (“APL”) (NYSE: APL), completed an acquisition of assets from Atlas Energy, which included its investment management business, proved reserves located in the Appalachian Basin, New Albany Shale, Antrim Shale, Chattanooga Shale and Niobrara formations, and other assets. Subsequent to the transaction, AHD changed its name to Atlas Energy, L.P. and assumed control of Atlas Resources.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

In management’s opinion, all adjustments necessary for a fair presentation of the Partnership’s financial position, results of operations and cash flows for the periods disclosed have been made. Management has considered for disclosure any material subsequent events through the date the financial statements were issued.

Use of Estimates

The preparation of the Partnership’s 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 disclosure of contingent assets and liabilities that exist at the date of the Partnership’s financial statements, as well as the reported amounts of revenue and costs and expenses during the reporting periods. The Partnership’s financial statements are based on a number of significant estimates, including the revenue and expense accruals, depletion, asset impairments, fair value of derivative instruments, and the probability of forecasted transactions. Actual results could differ from those estimates.

The natural gas industry principally conducts its business by processing actual transactions as much as 60 days after the month of delivery. Consequently, the most recent two months’ financial results were recorded using estimated volumes and contract market prices. Differences between estimated and actual amounts are recorded in the following month’s financial results. Management believes that the operating results presented for the period ended December 31, 2010 represent actual results in all material respects (see “Revenue Recognition” accounting policy for further description).

Accounts 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 review of its customers’ credit information. Credit is extended on an unsecured basis to many of its energy customers. At December 31, 2010 the Partnership’s MGP’s credit evaluation indicated that the Partnership had no need for an allowance for possible losses.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Fair Value of Financial Instruments

The carrying amounts of the Partnership’s cash and receivables approximate fair values because of the short maturities of these instruments.

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 period ended December 31, 2010.

Oil and Gas Properties

Oil and gas properties are stated at cost. Maintenance and repairs are expensed as incurred. Major renewals and improvements that extend the useful lives of property are capitalized. The Partnership follows the successful efforts method of accounting for oil and gas producing activities. Oil is converted to gas equivalent basis (“Mcfe”) at the rate of one barrel equals 6 Mcf.

The Partnership’s depletion expense is determined on a field-by-field basis using the units-of-production method. Depletion rates for lease, well and related equipment costs are based on proved developed reserves associated with each field. Depletion rates are determined based on reserve quantity estimates and the capitalized costs of developed producing properties. Upon the sale or retirement of a complete field of a proved property, the Partnership eliminates the cost from the property accounts and the resultant gain or loss is reclassified to the Partnership’s statement of operations. The Partnership recorded $1,279,000 of dry hole costs for the period ended December 31, 2010 from oil and gas properties to the statement of operations from the retirement of Tennessee producing activities. Upon the sale of an individual well, the Partnership credits the proceeds to accumulated depreciation and depletion within its balance sheet. As a result of retirements, the Partnership reclassified $704,700 for the period ended December 31, 2010, from oil and gas properties to accumulated depletion. At December 31, 2010, construction in progress was $65,071,800, which represented Limited Partner funds paid to the MGP for the completion of natural gas and oil wells.

Impairment of Long-Lived Assets

The Partnership reviews its long-lived assets for impairment whenever events or changes in 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.

DECEMBER 31, 2010

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Impairment of Long-Lived Assets (Continued)

The review of the Partnership’s oil and gas properties is done on a field-by-field basis by determining if the historical cost of proved properties less the applicable accumulated depletion, depreciation and amortization and abandonment 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 proved reserves. Expected future cash flow from the sale of production of reserves is calculated based on estimated future prices. The Partnership estimates prices based upon current contracts in place, adjusted for basis differentials and market related information including published futures prices. The estimated future level of production is based on assumptions surrounding future prices and costs, field decline rates, market demand and supply and the economic and regulatory climates. If the carrying value exceeds the expected future cash flows, an impairment loss is recognized for the difference between the estimated fair market value (as determined by discounted future cash flows) and the carrying value of the assets.

The determination of oil and natural gas reserve estimates is a subjective process and the accuracy of any reserve estimate depends on the quality of available data and the application of engineering and geological interpretation and judgment. Estimates of economically recoverable reserves and future net cash flows depend on a number of variable factors and assumptions that are difficult to predict and may vary considerably from actual results. During the period ended December 31, 2010, the Partnership did not recognize an asset impairment related to oil and gas properties.

Working Interest

The Partnership Agreement establishes that revenues and expenses will be allocated to the MGP and limited partners based on their ratio of capital contributions to total contributions (“working interest”). The MGP is also provided an additional working interest of 10% as provided in the Partnership Agreement. Due to the time necessary to complete drilling operations and accumulate all drilling costs, estimated working interest percentage ownership rates are utilized to allocate revenues and expenses until the wells are completely drilled and turned on-line into production. Once the wells are completed, the final working interest ownership of the partners is determined and any previously allocated revenues and expenses based on the estimated working interest percentage ownership are adjusted to conform to the final working interest percentage ownership.

Revenue Recognition

The Partnership generally sells natural gas and crude oil at prevailing market prices. Revenue is recognized when produced quantities are delivered to a custody transfer point, persuasive evidence of a sales arrangement exists, the rights and responsibility of ownership pass to the purchaser upon delivery, collection of revenue from the sale is reasonably assured and the sales price is fixed or determinable. Revenues from the production of natural gas and crude oil in which the Partnership has an interest with other producers are recognized on the basis of the Partnership’s percentage ownership of working interest. Generally, the Partnership’s sales contracts are based on pricing provisions that are tied to a market index with certain adjustments based on proximity to gathering and transmission lines and the quality of its natural gas.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Revenue Recognition (Continued)

The Partnership accrues unbilled revenue due to timing differences between the delivery of natural gas and crude oil and the receipt of a delivery statement. These revenues are recorded based upon volumetric data from the Partnership’s records and management estimates of the related commodity sales and transportation fees which are, in turn, based upon applicable product prices (see “Use of Estimates” accounting policy for further description). The Partnership had unbilled revenues at December 31, 2010 of $856,100, which are included in accounts receivable — affiliate within the Partnership’s balance sheet.

Asset Retirement Obligation

The Partnership recognizes an estimated liability for the plugging and abandonment of its oil and gas wells and related facilities, or asset retirement obligations (see Note 5). The Partnership recognizes a liability for future asset retirement obligations in the current period if a reasonable estimate of the fair value of the liability can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset.

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.

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 period ended December 31, 2010, the Partnership had no environmental matters requiring specific disclosure or the recording of a liability.

Comprehensive Income

Comprehensive income includes net loss and all other changes in equity of a business during a period from non-owner sources that, under accounting principles generally accepted in the United States of America, have not been recognized in the calculation of net loss, these changes, other than net loss, are referred to as “other comprehensive income, and for the Partnership include changes in the fair value of unsettled derivative contracts accounted for as cash flow hedges.

Recently Adopted Accounting Standards

In April 2010, the FASB issued Accounting Standards Update 2010-14, “Accounting for Extractive Industries — Oil & Gas: Amendments to Paragraph 932-10-S99-1” (“Update 2010-14”). Update 2010-14 provides amendments to add the SEC’s Regulation S-X Rule 4-10, “Financial Accounting and Reporting for Oil and Gas Producing Activities Pursuant to the Federal Securities Laws and the Energy Policy and Conservation Act of 1975” (“S-X Rule 4-10”) to Accounting Standards Codification (“ASC”) Topic 932 “Extractive Activities — Oil and Gas”. S-X Rule 4-10 was included in the SEC’s Final Rule, “Modernization of Oil and Gas Reporting, which became effective January 1, 2010. As Update 2010-14 only served to align the FASB’s ASC Topic 932 with the SEC’s S-X Rule 4-10, its adoption did not have a material impact on the Partnership’s financial position, results of operations or related disclosures.

In February 2010, the FASB issued Accounting Standards Update 2010-09, “Subsequent Events (Topic 855): Amendments to Certain Recognition and Disclosure Requirements” (“Update 2010-09”). Update 2010-09 removes the requirement for an SEC filer to disclose a date through which subsequent events have been evaluated in both issued and revised financial statements. Revised financial statements include financial statements revised as a result of either correction of an error or retrospective application of U.S. generally accepted accounting standards. The requirements of Update 2010-09 were effective upon its issuance on February 24, 2010. The requirements of Update 2010-09 were applied upon its adoption, and it did not have an impact on the Partnership financial position, results of operations or related disclosures.

In January 2010, the FASB issued Accounting Standards Update 2010-06, “Fair Value Measurement and Disclosures (Topic (820) — Improving Disclosures about Fair Value Measurement” (“Update 2010-06”). Update 2010-06 clarifies and requires new disclosures about the transfer of amounts between Level 1 and Level 2, as well as significant transfers in and out of Level 3. In addition, for Level 2 and Level 3 measurements, Update 2010-06 requires additional disclosure about the valuation technique used or any changes in technique. Update 2010-06 also clarifies that entities must disclose fair value measurements by classes of assets and liabilities, based on the nature and risks of the assets and liabilities. The requirements of Update 2010-06 are effective at the start of a reporting entity’s first fiscal year beginning after December 15, 2009 (January 1, 2010 for the Partnership). The requirements of Update 2010-06 were applied upon its adoption on April 1, 2010 and it did not have a material impact on the Partnership’s financial position, results of operations or related disclosures.

Major Customers

The Partnership’s natural gas is sold under contract to various purchasers. For the period ended December 31, 2010, sales to Atmos Energy Marketing, LLC accounted for 98%, of total revenues. No other customers accounted for 10% or more of total revenues for the period ended December 31, 2010.

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 their pro rata share of all items of partnership income and deductions in computing their federal income tax liability.

NOTE 3 — PARTICIPATION IN REVENUES AND COSTS

The MGP and the limited partners will generally participate in revenues and costs in the following manner:

	Managing
	General			Limited
	Partner			Partners
Organization and offering costs		100	%		0	%
Lease costs		100	%		0	%
Revenues (1)		33.75	%		66.25	%

Intangible drilling costs		0	%		100	%
Tangible equipment costs		46	%		54	%

(1)	Subject to the MGP’s subordination obligation, substantially all partnership revenues will be shared in the same percentage as capital contributions are to the total partnership capital contributions, except that the MGP will receive an additional 10% of the partnership revenues.
(2)	These costs will be charged to the partners in the same ratio as the related production revenues are credited.

NOTE 5 — ASSET RETIREMENT OBLIGATION

The Partnership recognizes an estimated liability for the plugging and abandonment of its oil and gas wells and related facilities. It also recognizes a liability for future asset retirement obligations if a reasonable estimate of the fair value of that liability can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. The Partnership also considers the estimated salvage value in the calculation of depletion.

The estimated liability is based on the MGP’s 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 liability is discounted using an assumed credit-adjusted risk-free interest rate. Revisions to the liability could occur due to changes in estimates of plugging and abandonment costs or remaining lives of the wells or if federal or state regulators enact new plugging and abandonment requirements. The Partnership has no assets legally restricted for purposes of settling asset retirement obligations. Except for its oil and gas properties, the Partnership has determined that there are no other material retirement obligations associated with tangible long-lived assets.

A reconciliation of the Partnership’s liability for well plugging and abandonment costs for the period indicated is as follows:

	Period
	Ended
	December 31,
	2010
Asset retirement obligation at beginning of period	$	—
Liabilities incurred from drilling wells		1,407,800
Asset retirement obligations at end of year	$	1,407,800

NOTE 6 — DERIVATIVE INSTRUMENTS

The MGP on behalf of the Partnership uses a number of different derivative instruments, principally swaps, collars and options, in connection with its commodity price risk management activities. The MGP enters into financial instruments to hedge its forecasted natural gas and crude oil sales against the variability in expected future cash flows attributable to changes in market prices. Swap instruments are contractual agreements between counterparties to exchange obligations of money as the underlying natural gas and crude oil is sold. Under swap agreements, the MGP receives or pays a fixed price and receives or remits a floating price based on certain indices for the relevant contract period. Commodity-based option instruments are contractual agreements that grant the right, but not obligation, to purchase or sell natural gas and crude oil at a fixed price for the relevant contract period.

83

ATLAS RESOURCES SERIES 28-2010 L.P.
NOTES TO FINANCIAL STATEMENTS (Continued)
DECEMBER 31, 2010

NOTE 6 — DERIVATIVE INSTRUMENTS (Continued)

The MGP formally documents all relationships between hedging instruments and the items being hedged, including its risk management objective and strategy for undertaking the hedging transactions. This includes matching the commodity derivative contracts to the forecasted transactions. The MGP assesses, both at the inception of the derivative and on an ongoing basis, whether the derivative is effective in offsetting changes in the forecasted cash flow of the hedged item. If it is determined that a derivative is not effective as a hedge or that it has ceased to be an effective hedge due to the loss of adequate correlation between the hedging instrument and the underlying item being hedged, the MGP will discontinue hedge accounting for the derivative and subsequent changes in the derivative fair value, which is determined by the MGP through the utilization of market data, will be recognized immediately within gain (loss) on mark-to-market derivatives in the Partnership’s statement of operations. For derivatives qualifying as hedges, the Partnership recognizes the effective portion of changes in fair value in partners’ capital as accumulated other comprehensive income and reclassifies the portion relating to commodity derivatives to gas and oil production revenues for the Partnership’s derivatives within the Partnership’s statement of operations as the underlying transactions are settled. For non-qualifying derivatives and for the ineffective portion of qualifying derivatives, the Partnership recognizes changes in fair value within gain (loss) on mark-to-market derivatives in its statement of operations as they occur.

Derivatives are recorded on the Partnership’s balance sheet as assets or liabilities at fair value. The Partnership reflected a net derivative asset on its balance sheet of $2,824,700 at December 31, 2010. Of the $2,824,700 net unrealized gain in accumulated other comprehensive income at December 31, 2010, if the fair values of the instruments remain at current market values, the Partnership will reclassify $1,321,200 of gains to the Partnership’s statement of operations over the next twelve month period as these contracts expire. Aggregate gains of $1,503,500 will be reclassified to the Partnership’s statement of operations in later periods as these remaining contracts expire. Actual amounts that will be reclassified will vary as a result of future price changes.

The following table summarizes the fair value of the Partnership’s derivative instruments as of December 31, 2010, as well as the gain or loss recognized in the statement of operations for effective derivative instruments for the period ended December 31, 2010:

NOTE 6 — DERIVATIVE INSTRUMENTS (Continued)

The MGP enters into natural gas and crude oil future option contracts and collar contracts to achieve more predictable cash flows by hedging its exposure to changes in natural gas and oil prices. At any point in time, such contracts may include regulated New York Mercantile Exchange (“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. Crude 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.

In December 2010, the MGP, on behalf of the Partnership, allocated approximately $2,500 in net proceeds from the early settlement of natural gas derivative positions for production periods during 2012. The gain realized upon the early terminations of these derivative positions is reported in accumulated other comprehensive income and will be reclassified to the Partnership’s statement of operations in the same periods in which the hedged production revenues would have been recognized in earnings. The $2,500 in net proceeds is recorded in the hedge receivable balance on the Partnership’s balance sheet at December 31, 2010.

As of December 31, 2010, Atlas Energy had allocated to the Partnership the following natural gas volumes hedged:

Natural Gas Fixed Price Swaps

NOTE 7 — FAIR VALUE OF FINANCIAL INSTRUMENTS

The Partnership has established a hierarchy to measure its financial instruments at fair value which requires it to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The hierarchy defines three levels of inputs that may be used to measure fair value.

Level 1 — Unadjusted quoted prices in active markets for identical unrestricted 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 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.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The Partnership uses a fair value methodology to value the assets and liabilities for its outstanding derivative contracts (see Note 6). The Partnership’s commodity derivative contracts are valued based on observable market data related to the change in price of the underlying commodity and are therefore defined as Level 2 fair value measurements.

NOTE 7 — FAIR VALUE OF FINANCIAL INSTRUMENTS (Continued)

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

The Partnership estimates the fair value of asset retirement obligations using Level 3 inputs based on discounted cash flow projections using numerous estimates, assumptions and judgments regarding such factors at the date of establishment of an asset retirement obligation such as: amounts and timing of settlements; the credit-adjusted risk-free rate of the Partnership; and estimated inflation rates (see Note 5).

NOTE 8 — CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

The Partnership has entered into the following significant transactions with its MGP and its affiliates as provided under the Partnership Agreement:

• Drilling contracts to drill and complete wells for the Partnership are charged at cost plus 18%. The cost of the wells includes reimbursement to the Partnership’s MGP of its general and administrative overhead cost. The Partnership paid $149,724,600 to its MGP for the period ended December 31, 2010.

• The Partnership’s MGP contributed undeveloped leases necessary to cover each of the Partnership’s prospects and as of December 31, 2010 received a credit to its capital account in the Partnership of $5,053,800.

• Administrative costs which are included in general and administrative expenses in the Partnership’s statement of operations are payable at $75 per well per month. Administrative costs incurred during the period ended December 31, 2010 were $12,100.

• Monthly well supervision fees which are included in production expenses in the Partnership’s statement of operations are payable at $975 per well per month for Marcellus wells, $1,500 per well per month for New Albany wells, $600 per well per month for horizontal Antrim Shale wells, and for Colorado wells, a fee of $400 is charged per well per month for operating and maintaining the wells. Well supervision fees incurred during the period ended December 31, 2010 were $222,300.

• Transportation fees, which are included in production expenses in the Partnership’s statement of operations, incurred during the period ended December 31, 2010 were $15,800.

NOTE 8 — CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS (Continued)

• Assets contributed from the MGP, which are disclosed on the Partnership’s statement of cash flows as non-cash investing and financing activities, for the period ended December 31, 2010, were $17,642,100.

• The MGP received a credit to its capital account of $16,267,000 for the period ended December 31, 2010 for fees, commissions and reimbursement costs to organize the Partnership.

The MGP and its affiliates perform all administrative and management functions for the Partnership including billing revenues and paying expenses. Accounts receivable—affiliate on the Partnership’s balance sheet represents the net production revenues due from the MGP.

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 net production revenues of the Partnership to the benefit of the limited partners for an amount equal to at least 12% of their net subscriptions in the first 12-month subordination period, 10% of their net subscriptions in each of the next three 12-month subordination periods, and 8% of their net subscriptions in the fifth 12-month subordination period determined on a cumulative basis, in each of the first five years of Partnership operations, commencing when the MGP determines natural gas or oil is being sold from at least 75% of the partnership’s wells, excluding any wells drilled that were non-productive and expiring 60 months from that date.

NOTE 9 — COMMITMENTS AND CONTINGENCIES

Subject to certain conditions, investor partners may present their interests beginning in 2015 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, it 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 estimated future plugging and abandonment costs. As of December 31, 2010, the MGP has not withheld any such funds.

Legal Proceedings

The Managing General Partner is not aware of any legal proceedings filed against the Partnership.

The Partnership’s MGP 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.

(2) Oil and Gas Reserve Information

The preparation of the Partnership’s natural gas and oil reserve estimates were completed in accordance with its prescribed internal control procedures, which include verification of input data delivered to its third-party reserve specialist, as well as a multi-functional management review. For the period ended December 31, 2010, the Partnership retained Wright & Company, independent, third-party reserves engineers, to prepare a report of proved reserves. The reserves report included a detailed review of our properties. Wright & Company’s evaluation was based on more than 35 years of experience in the estimation of and evaluation of petroleum reserves, specified economic parameters, operating conditions, and government regulations applicable as of December 31, 2010. The Wright & Company report was prepared in accordance with generally accepted petroleum engineering and evaluation principles.

The reserve disclosures that follow reflect estimates of proved reserves consisting of proved developed, net to the Partnership’s interests, of natural gas, crude oil, condensate and NGLs owned at year end and changes in proved reserves during the previous two years. Proved developed reserves are those proved reserves, which can be expected to be recovered from existing wells with existing equipment and operating methods.

There are numerous uncertainties inherent in estimating quantities of proven 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 oil and gas reserves or the present value of future cash flows of equivalent reserves, due to anticipated future changes in oil and gas prices and in production and development costs and other factors for effects have not been proved.

NOTE 11 — SUBSEQUENT EVENTS

Atlas Energy, Inc. Asset Acquisition

On February 17, 2011, Atlas Pipeline Holdings, L.P. (“AHD”) (NYSE: AHD), a then-majority owned subsidiary of Atlas Energy and parent of the general partner to Atlas Pipeline Partners, L.P. (“APL”) (NYSE: APL), completed an acquisition of assets from Atlas Energy, which included its investment management business, proved reserves located in the Appalachian Basin, New Albany Shale, Antrim Shale, Chattanooga Shale and Niobrara formations, and other assets (“Asset Acquisition”). As part of the transaction, Atlas Resources, LLC became an indirect subsidiary of AHD. Concurrent with the Asset Acquisition, Atlas Energy and its subsidiaries completed a merger transaction with Chevron Corporation (“Chevron”), whereby each share of Atlas Energy was converted into the right to receive $38.25 in cash as well as a pro rata distribution of all AHD common units owned by Atlas Energy, and Atlas Energy became a wholly-owned subsidiary of Chevron (“Merger”). Subsequent to the Merger, AHD changed its name to Atlas Energy, L.P.

Laurel Mountain Sale

Concurrently with the completion of the Asset Acquisition, APL, an affiliate of the MGP, completed its sale to Atlas Energy Resources, LLC of its 49% non-controlling interest in the Laurel Mountain joint venture.

Hedge Monetization

In conjunction with the “Asset Acquisition,” Atlas Energy monetized all derivative contracts related to natural gas and oil production. The Partnership will share in the total available hedge gains with all other Partnerships sponsored by the MGP. Each Partnership will participate in the monetized funds based on its production volumes during the period of the original derivative contracts.

NOTES TO FINANCIAL STATEMENTS

March 31, 2011

(Unaudited)

NOTE 1 — DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

Atlas Resources Series 28-2010 L.P. (the “Partnership”) is a Delaware limited partnership, formed on April 2010 with Atlas Resources, LLC serving as its Managing General Partner and operator (“Atlas Resources” or “MGP”). Atlas Resources is an indirect subsidiary of Atlas Energy, L.P., formerly Atlas Pipeline Holdings, L.P. (“Atlas Energy”) (NYSE: ATLS). On February 17, 2011, Atlas Energy, a then-majority owned subsidiary of Atlas Energy, Inc. and parent of the general partner of Atlas Pipeline Partners, L.P. (“APL”) (NYSE: APL), completed an acquisition of assets from Atlas Energy, Inc., which included its investment partnership business; its oil and gas exploration, development and production activities conducted in Tennessee, Indiana, and Colorado, certain shallow wells and leases in New York and Ohio, and certain well interests in Pennsylvania and Michigan; and its ownership and management of investments in Lightfoot Capital Partners, L.P. and related entities.

Atlas Resources’ focus is on the development and/or production of natural gas and oil in the Appalachian, Michigan, Illinois, and/or Colorado basin regions of the United States of America. Atlas Resources is also a leading sponsor of and manages tax-advantaged direct investment partnerships, in which it co-invests to finance the exploitation and development of its acreage. Atlas Energy Resource Services, Inc. provides Atlas Resources with the personnel necessary to manage its assets and raise capital.

The accompanying financial statements, which are unaudited except that the balance sheet at December 31, 2010, is derived from audited financial statements, are presented in accordance with the requirements of Form 10-Q and accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim reporting. They do not include all disclosures normally made in financial statements contained in the Form 10-K. These interim financial statements should be read in conjunction with the audited financial statements and notes thereto presented in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2010. The results of operations for the three months ended March 31, 2011 may not necessarily be indicative of the results of operations for the year ended December 31, 2011.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

In management’s opinion, all adjustments necessary for a fair presentation of the Partnership’s financial position, results of operations and cash flows for the periods disclosed have been made. Management has considered for disclosure any material subsequent events through the date the financial statements were issued.

In addition to matters discussed further in this note, the Partnership’s significant accounting policies are detailed in its audited financial statements and notes thereto in the Partnership’s Form 10-K for the year ended December 31, 2010 filed with the Securities and Exchange Commission (“SEC”).

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 that exist at the date of the Partnership’s financial statements, as well as the reported amounts of revenues and costs and expenses during the reporting periods. The Partnership’s financial statements are based on a number of significant estimates, including the revenue and expense accruals, depletion, asset impairments, fair value of derivative instruments and the probability of forecasted transactions. Actual results could differ from those estimates.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Use of Estimates (Continued)

The natural gas industry principally conducts its business by processing actual transactions as much as 60 days after the month of delivery. Consequently, the most recent two months’ financial results were recorded using estimated volumes and contract market prices. Differences between estimated and actual amounts are recorded in the following months’ financial results. Management believes that the operating results presented for the three months ended March 31, 2011 and 2010 represent actual results in all material respects (see “Revenue Recognition” accounting policy for further description).

Accounts 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 customers’ current creditworthiness as determined by review of its customers’ credit information. Credit is extended on an unsecured basis to many of its energy customers. At March 31, 2011 and December 31, 2010, the Partnership’s MGP’s credit evaluation indicated that the Partnership had no need for an allowance for possible losses.

Oil and Gas Properties

Oil and gas properties are stated at cost. Maintenance and repairs are expensed as incurred. Major renewals and improvements that extend the useful lives of property are capitalized. The Partnership follows the successful efforts method of accounting for oil and gas producing activities. Oil is converted to gas equivalent basis (“Mcfe”) at the rate of one barrel equals 6 Mcf.

The Partnership’s depletion expense is determined on a field-by-field basis using the units-of-production method. Depletion rates for lease, well and related equipment costs are based on proved developed reserves associated with each field. Depletion rates are determined based on reserve quantity estimates and the capitalized costs of developed producing properties. As a result of retirements, the Partnership reclassified $304,400 from oil and gas properties to accumulated depletion for the three months ended March 31, 2011.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Impairment of Long-Lived Assets

The Partnership reviews its long-lived assets for impairment whenever events or changes in 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.

The review of the Partnership’s oil and gas properties is done on a field-by-field basis by determining if the historical cost of proved properties, less the applicable accumulated depletion, and abandonment 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. Expected future cash flow from the sale of production of reserves is calculated based on estimated future prices. The Partnership estimates prices based upon current contracts in place, adjusted for basis differentials and market related information including published futures prices. The estimated future level of production is based on assumptions surrounding future prices and costs, field decline rates, market demand and supply and the economic and regulatory climates. If the carrying value exceeds the expected future cash flows, an impairment loss is recognized for the difference between the estimated fair market value (as determined by discounted future cash flows) and the carrying value of the assets.

The determination of oil and natural gas reserve estimates is a subjective process and the accuracy of any reserve estimate depends on the quality of available data and the application of engineering and geological interpretation and judgment. Estimates of economically recoverable reserves and future net cash flows depend on a number of variable factors and assumptions that are difficult to predict and may vary considerably from actual results. In addition, reserve estimates for wells with limited or no production history are less reliable than those based on actual production. Estimated reserves are often subject to future revisions, which could be substantial, based on the availability of additional information which could cause the assumptions to be modified. The Partnership cannot predict what reserve revisions may be required in future periods. There was no impairment charge recognized during the three months ended March 31, 2011.

Working Interest

The Partnership Agreement establishes that revenues and expenses will be allocated to the MGP and limited partners based on their ratio of capital contributions to total contributions (“working interest”). The MGP is also provided an additional working interest of 10% as provided in the Partnership Agreement. Due to the time necessary to complete drilling operations and accumulate all drilling costs, estimated working interest percentage ownership rates are utilized to allocate revenues and expenses until the wells are completely drilled and turned on-line into production. Once the wells are completed, the final working interest ownership of the partners is determined and any previously allocated revenues and expenses based on the estimated working interest percentage ownership are adjusted to conform to the final working interest percentage ownership.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Revenue Recognition

The Partnership generally sells natural gas and crude oil at prevailing market prices. Revenue is recognized when produced quantities are delivered to a custody transfer point, persuasive evidence of a sales arrangement exists, the rights and responsibility of ownership pass to the purchaser upon delivery, collection of revenue from the sale is reasonably assured and the sales price is fixed or determinable. Revenues from the production of natural gas and crude oil in which the Partnership has an interest with other producers are recognized on the basis of the Partnership’s percentage ownership of working interest. Generally, the Partnership’s sales contracts are based on pricing provisions that are tied to a market index with certain adjustments based on proximity to gathering and transmission lines and the quality of its natural gas.

The Partnership accrues unbilled revenue due to timing differences between the delivery of natural gas and crude oil and the receipt of a delivery statement. These revenues are recorded based upon volumetric data from the Partnership’s records and management estimates of the related commodity sales and transportation fees which are, in turn, based upon applicable product prices (see “Use of Estimates” accounting policy for further description). The Partnership had unbilled revenues at March 31, 2011 and December 31, 2010 of $1,676,400 and $856,100, respectively, which are included in accounts receivable — affiliate within the Partnership’s balance sheets.

Recently Adopted Accounting Standards

As of the date of this filing, there are no newly issued accounting standards which impacted the presentation of the attached financial statements that have not already been adopted.

NOTE 3 — ASSET RETIREMENT OBLIGATION

The Partnership recognizes an estimated liability for the plugging and abandonment of its oil and gas wells and related facilities. It also recognizes a liability for future asset retirement obligations if a reasonable estimate of the fair value of that liability can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. The Partnership also considers the estimated salvage value in the calculation of depletion.

The estimated liability is based on the MGP’s 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 liability is discounted using an assumed credit-adjusted risk-free interest rate. Revisions to the liability could occur due to changes in estimates of plugging and abandonment costs or remaining lives of the wells or if federal or state regulators enact new plugging and abandonment requirements. The Partnership has no assets legally restricted for purposes of settling asset retirement obligations. Except for its oil and gas properties, the Partnership has determined that there are no other material retirement obligations associated with tangible long-lived assets.

NOTE 4 — COMPREHENSIVE LOSS

Comprehensive loss includes net income and all other changes in equity of a business during a period from transactions and other events and circumstances from non-owner sources that, under accounting principles generally accepted in the United States of America, have not been recognized in the calculation of net income. These changes, other than net income, are referred to as “other comprehensive income” and, for the Partnership, include changes in the fair value of unsettled derivative contracts accounted for as cash flow hedges. A reconciliation of the Partnership’s comprehensive loss for the period indicated is as follows:

	Three Months
	Ended
	March 31, 2011
Net income	$	386,200
Other comprehensive loss:
Unrealized holding loss on hedging contracts		(123,700	)
Less: reclassification adjustment for gains realized in net income		(290,000	)
Total other comprehensive loss		(413,700	)
Comprehensive loss	$	(27,500	)

NOTE 5 — DERIVATIVE INSTRUMENTS

The MGP, on behalf of the Partnership, uses a number of different derivative instruments, principally swaps and collars, in connection with its commodity price risk management activities. The MGP enters into financial instruments to hedge the Partnership’s forecasted natural gas and crude oil against the variability in expected future cash flows attributable to changes in market prices. Swap instruments are contractual agreements between counterparties to exchange obligations of money as the underlying natural gas and crude oil is sold. Under swap agreements, the Partnership receives or pays a fixed price and receives or remits a floating price based on certain indices for the relevant contract period. Commodity-based option instruments are contractual agreements that grant the right, but not obligation, to purchase or sell natural gas and crude oil at a fixed price for the relevant contract period.

NOTE 5 — DERIVATIVE INSTRUMENTS (Continued)

Historically, the MGP has entered into natural gas and crude oil future option contracts and collar contracts on behalf of the Partnership to achieve more predictable cash flows by hedging its exposure to changes in natural gas and oil prices. At any point in time, such contracts may include regulated New York Mercantile Exchange (“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. Crude 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 MGP formally documents all relationships between hedging instruments and the items being hedged, including its risk management objective and strategy for undertaking the hedging transactions. This includes matching the commodity derivative contracts to the forecasted transactions. The MGP assesses, both at the inception of the derivative and on an ongoing basis, whether the derivative is effective in offsetting changes in the forecasted cash flow of the hedged item. If it is determined that a derivative is not effective as a hedge or that it has ceased to be an effective hedge due to the loss of adequate correlation between the hedging instrument and the underlying item being hedged, the MGP will discontinue hedge accounting for the derivative and subsequent changes in the derivative fair value, which is determined by the MGP through the utilization of market data, will be recognized immediately within gain (loss) on mark-to-market derivatives in the Partnership’s statements of operations. For derivatives qualifying as hedges, the Partnership recognizes the effective portion of changes in fair value in partners’ capital as accumulated other comprehensive income and reclassifies the portion relating to commodity derivatives to gas and oil production revenues for the Partnership’s derivatives within the Partnership’s statements of operations as the underlying transactions are settled. For non-qualifying derivatives and for the ineffective portion of qualifying derivatives, the Partnership recognizes changes in fair value within gain (loss) on mark-to-market derivatives in its statements of operations as they occur.

Prior to the acquisition on February 17, 2011 (“the Transferred Business”), ATLS monetized its derivative instruments related to the Transferred Business. The monetized proceeds relate to instruments that were originally put into place to hedge future natural gas and oil production of the Transferred Business, including production generated through its Drilling Partnerships. At March 31, 2011, the Partnership recorded a net receivable from the monetized derivative instruments of $1,090,900 in accounts receivable-affiliate and $1,320,100 in long-term receivable-affiliate with the corresponding net unrealized gains in accumulated other comprehensive income on the Partnership’s balance sheets, which will be allocated to natural gas and oil production revenue over the period of the original instruments’ contracts. As a result of the early settlement of natural gas and oil derivative positions, the Partnership recorded a net deferred gain on its balance sheets in other comprehensive income of $2,411,000 as of March 31, 2011. During the period, $72,000 of monetized proceeds were recorded by the Partnership and allocated to the limited partners only. Of the $2,411,000 of net unrealized gain in accumulated other comprehensive income, the Partnership will reclassify $1,090,900 of net gains to the Partnership’s statements of operations over the next twelve month period and the remaining $1,320,100 in later periods.

NOTE 6 — FAIR VALUE OF FINANCIAL INSTRUMENTS

The Partnership has established a hierarchy to measure its financial instruments at fair value which requires it to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The 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 entities 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.

NOTE 6 — FAIR VALUE OF FINANCIAL INSTRUMENTS (Continued)

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The Partnership used a fair value methodology to value the assets and liabilities for its outstanding derivative contracts (see Note 5). The Partnership’s commodity derivative contracts were valued based on observable market data related to the change in price of the underlying commodity and are therefore defined as Level 2 fair value measurements.

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

The Partnership estimates the fair value of asset retirement obligations using Level 3 inputs based on discounted cash flow projections using numerous estimates, assumptions and judgments regarding such factors at the date of establishment of an asset retirement obligation such as: amounts and timing of settlements; the credit-adjusted risk-free rate of the Partnership; and estimated inflation rates (see Note 3).

NOTE 7 — TRANSACTIONS WITH ATLAS RESOURCES, LLC AND ITS AFFILIATES

The Partnership commenced operations on April 1, 2010 and had production begin in June 2010, therefore no comparative data is available for the three months ended March 31, 2010.

The Partnership has entered into the following significant transactions with its MGP and its affiliates as provided under its Partnership Agreement:

• Monthly well supervision fees which are included in production expenses in the Partnership’s Statement of Operations are payable at $975 per well, per month for Marcellus wells, $1,500 per well, per month for New Albany wells and, $600 per well, per month for horizontal Antrim Shale wells and for Colorado wells, a fee of $400 is charged per well, per month for operating and maintaining the wells. Well supervision fees incurred were $201,800 for the three months ended March 31, 2011.

• Administrative costs which are included in general and administrative expenses in the Partnership’s statement of operations are payable at $75 per well per month. Administrative costs incurred for the three months ended March 31, 2011 were $13,600.

• Transportation fees, which are included in production expenses in the Partnership’s statement of operations, incurred for the three months ended March 31, 2011 were $110,100.

• Assets contributed from the MGP which are disclosed on the Partnership’s statement of cash flows as a non-cash activity for the three months ended March 31, 2011 were $3,975,800.

The MGP and its affiliates perform all administrative and management functions for the Partnership including billing revenues and paying expenses. Accounts receivable-affiliate on the Partnership’s balance sheets represents the net production revenues due from the MGP.

DRILLING AND OPERATING AGREEMENT

THIS AGREEMENT made this 15th day of May, 2010, by and between ATLAS RESOURCES, LLC, a Pennsylvania limited liability company (hereinafter referred to as “Atlas” or “Operator”),

and

ATLAS RESOURCES SERIES 28-2010 L.P., a Delaware limited partnership, (hereinafter referred to as the “Developer”).

WITNESSETH THAT:

WHEREAS, the Operator, by virtue of the Oil and Gas Leases (the “Leases”) described on Exhibit A attached to and made a part of this Agreement, has certain rights to develop the One Hundred Twenty Seven (127) initial well locations (the “Initial Well Locations”) identified on the maps attached to and made a part of this Agreement as Exhibits A-1 through A-                     ;

WHEREAS, the Developer, subject to the terms and conditions of this Agreement, desires to acquire certain of the Operator’s rights to develop the Initial Well Locations and to provide for the development on the terms and conditions set forth in this Agreement of additional well locations (“Additional Well Locations”) that the parties may from time to time designate; and

WHEREAS, the Operator is in the oil and gas exploration and development business, and the Developer desires that Operator, as its independent contractor, perform certain services in connection with its efforts to develop the aforesaid Initial and Additional Well Locations (collectively the “Well Locations”) and to operate the wells completed on the Well Locations, on the terms and conditions set forth in this Agreement;

NOW THEREFORE, in consideration of the mutual covenants herein contained and subject to the terms and conditions hereinafter set forth, the parties hereto, intending to be legally bound, hereby agreeas follows:

1. Assignment of Well Locations; Representations and Indemnification Associated with the Assignment of the Lease; Designation of Additional Well Locations; Outside Activities Are Not Restricted.

(a) Assignment of Well Locations. The Operator shall execute an assignment of an undivided percentage of Working Interest in the Well Location for each well to the Developer as shown on Exhibit A attached hereto, which assignment shall be limited by the Operator to the “Prospect” which is defined as the minimum area permitted by state law or local practice on which one well may be drilled, which may be different for different Horizons. Subject to the foregoing sentence, “Prospect” shall be deemed:

• the wellbore plus 125 feet on either side of the center line of a lateral in the well extending from the beginning of the first perforation to the end of the last perforation and from the bottom of the Tully zone to the bottom of the Marcellus Shale formation, in horizontal wells in the Marcellus Shale formation in western Pennsylvania;

• the wellbore plus 125 feet on either side of the center line of a lateral in the well extending from the beginning of the first perforation or open hole section to the end of the last perforation or last open hole section and from the top of the Borden Shale zone to the bottom of the New Albany zone, in horizontal wells in the New Albany Shale reservoir in Indiana;

• the wellbore plus 125 feet on either side of the center line of a lateral in the well extending from the beginning of the first perforation to the end of the last perforation and from the top of the Fort Payne zone to the bottom of the Chattanooga zone, in any horizontal wells in the Chattanooga Shale reservoir in Tennessee;

• the wellbore plus 125 feet on either side of the center line of a lateral in the well extending from the beginning of the first perforation to the end of the last perforation and from the top of the Lachine Member to the bottom of the Antrim zone, in any horizontal wells in the Antrim Shale reservoir in Michigan; and

1

The assignment shall be substantially in the form of Exhibit B attached to and made a part of this Agreement. The amount of acreage, or the wellbore, as the case may be, included in each Initial Well Location and the configuration of the Initial Well Location are indicated on the maps attached to this Agreement as Exhibits A-l through A-_____. The amount of acreage, or the wellbore, as the case may be, included in each Additional Well Location and the configuration of the Additional Well Location shall be indicated on the maps to be attached as exhibits to the applicable addendum to this Agreement as provided in sub-section (c) below.

(b) Representations and Indemnification Associated with the Assignment of the Lease. With respect to the Lease assignements described in Section 1(a), the Operator represents and warrants to the Developer that:

(i)	the Operator is the lawful owner of the Lease and rights and interest under the Lease and of the personal property on the Lease or used in connection with the Lease;
(ii)	the Operator has good right and authority to sell and convey the rights, interest, and property;
(iii)	the rights, interest, and property are free and clear from all liens and encumbrances; and
(iv)	all rentals and royalties due and payable under the Lease have been duly paid.

The Operator agrees to indemnify, protect and hold the Developer and its successors and assigns harmless from and against all costs (including but not limited to reasonable attorneys’ fees), liabilities, claims, penalties, losses, suits, actions, causes of action, judgments or decrees resulting from the breach of any of the above representations and warranties. It is understood and agreed that, except as specifically set forth above, the Operator makes no warranty or representation, express or implied, as to its title or the title of the lessors in and to the lands or oil and gas interests covered by said Leases.

(c) Designation of Additional Well Locations. If the parties hereto desire to designate Additional Well Locations to be developed in accordance with the terms and conditions of this Agreement, then the parties shall execute an addendum substantially in the form of Exhibit C attached to and made a part of this Agreement specifying:

(i) the undivided percentage of Working Interest and the Oil and Gas Leases to be included as Leases under this Agreement;

(ii) the amount and configuration of acreage included in each Additional Well Location on maps attached as exhibits to the addendum; and

(iii) their agreement that the Additional Well Locations shall be developed in accordance with the terms and conditions of this Agreement.

(d) Outside Activities Are Not Restricted. It is understood and agreed that the assignment of rights under the Leases and the oil and gas development activities contemplated by this Agreement relate only to the Initial Well Locations and the Additional Well Locations. Nothing contained in this Agreement shall be interpreted to restrict in any manner the right of each of the parties to conduct without the participation of the other party any additional activities relating to exploration, development, drilling, production, or delivery of oil and gas on lands adjacent to or in the immediate vicinity of the Well Locations or elsewhere.

2

2. Drilling of Wells; Timing; Depth; Interest of Developer; Right to Substitute Well Locations.

(a) Drilling of Wells. Operator, as Developer’s independent contractor, agrees to drill, complete (or plug) and operate One Hundred Twenty Seven (127) oil and gas wells on the One Hundred Twenty Seven (127) Initial Well Locations in accordance with the terms and conditions of this Agreement. Developer, as a minimum commitment, agrees to participate in and pay the Operator’s charges for drilling and completing (or plugging) the wells and any extra costs pursuant to Section 4 in proportion to the share of the Working Interest owned by the Developer in the wells with respect to all initial wells. It is understood and agreed that, subject to sub-section (e) below, Developer does not reserve the right to decline participation in the drilling of any of the initial wells to be drilled under this Agreement.

(b) Timing. Operator shall begin drilling the first well within thirty (30) days after the date of this Agreement, and shall begin drilling each of the other initial wells for which payment is made pursuant to Section 4(b) before the close of the 90^th day after the close of the calendar year in which this Agreement is entered into by Operator and the Developer. Subject to the foregoing time limits, Operator shall determine the timing of and the order of drilling the Initial Well Locations.

(c) Extent of Drilling. All of the wells to be drilled under this Agreement shall be:

(i)	drilled and completed (or plugged) in accordance with the generally accepted and customary oil and gas field practices and techniques then prevailing in the geographical area of the Well Locations; and
(ii)	drilled to a depth sufficient to test thoroughly the objective formation or the deepest assigned depth, whichever is less, in the case of a vertical well, and drilled vertically and horizontally to the extent of the assigned Lease interest necessary to thoroughly test the objective formation in the case of a horizontal well.

(d) Interest of Developer. Except as otherwise provided in this Agreement, all costs, expenses, and liabilities incurred in connection with the drilling and other operations and activities contemplated by this Agreement shall be borne and paid, and all wells, gathering lines of up to approximately 2,500 feet on each Well Location in connection with a natural gas well, equipment, materials, and facilities acquired, constructed or installed under this Agreement shall be owned, by the Developer in proportion to the share of the Working Interest owned by the Developer in the wells. Subject to the payment of lessor’s royalties and other royalties and overriding royalties, if any, production of oil and gas from the wells to be drilled under this Agreement shall be owned by the Developer in proportion to the share of the Working Interest owned by the Developer in the wells. Additionally, all costs, expenses, and liabilities incurred in connection with the leasing, developing, drilling, and operation of water disposal or injection wells, and the transportation or injection of waste water from Developer’s productive wells under this Agreement shall be the sole responsibility of Developer in proportion to the share of the Working Interest owned by the Developer. In the event Operator provides any services related to disposal wells, injection wells, transportation of waste water or similar matters under this Agreement, Operator shall be paid a monthly competitive fee, as determined by Developer and Operator.

(e) Right to Substitute Well Locations. Notwithstanding the provisions of sub-section (a) above, if the Operator or Developer determines in good faith, with respect to any Well Location, before operations begin under this Agreement on the Well Location, that it would not be in the best interest of the parties to drill a well on the Well Location, then the party making the determination shall notify the other party of its determination and the basis for its determination and, unless otherwise instructed by Developer, the well shall not be drilled. This determination may be based on:

(i) the production or failure of production of any other wells that may have been recently drilled in the immediate area of the Well Location;

3

(ii) newly discovered title defects; or

(iii) any other evidence with respect to the Well Location as may have been obtained.

If the well is not drilled, then Operator shall promptly propose a new well location (including all information for the Well Location as Developer may reasonably request) to be substituted for the original Well Location. Developer shall then have seven (7) business days to either reject or accept the proposed new well location. If the new well location is rejected, then Operator shall promptly propose another substitute well location pursuant to the provisions of this sub-section.

Once the Developer accepts a substitute well location or does not reject it within the seven (7) day period, this Agreement shall terminate as to the original Well Location and the substitute well location shall become subject to the terms and conditions of this Agreement.

4. Operator’s Charges for Drilling and Completing Wells; Payment; Completion Determination; Dry Hole Determination; Excess Funds and Cost Overruns-Intangible Drilling Costs; Excess Funds and Cost Overruns-Tangible Costs.

(a) Operator’s Charges for Drilling and Completing Wells. Each oil and gas well that is drilled and completed under this Agreement shall be drilled and completed for an amount equal to the sum of the following items: (i) the Cost of permits, supplies, materials, equipment, and all other items used in the drilling and completion of a well provided by third-parties, or if the foregoing items are provided by Affiliates of the Developer’s Managing General Partner, then those items shall be charged at competitive rates; (ii) fees for third-party services; (iii) fees for services provided by the Developer’s Managing General Partner’s Affiliates, which shall be charged at competitive rates; (iv) an administration and oversight fee at a competitive rate in the area where the well is situated, which is $244,222 per horizontal well in the Marcellus Shale primary area, and $46,122 per horizontal well in the New Albany Shale (Indiana) primary area; and (v) a mark-up in an amount equal to 18% of the sum of (i), (ii), (iii) and (iv), above, for the Developer’s Managing General Partner’s services as general drilling contractor as Operator under this Agreement.

5

“Cost” shall mean the price paid by Operator in an arm’s-length transaction. Additionally, if the Operator drills a well for the Developer that the Developer’s Managing General Partner determines is not an average well in the area because of the well’s depth, complexity associated with either drilling or completion activity or as otherwise determined by the Managing General Partner, the administration and oversight fee for the well described above, if applicable, and in §4.02(d)(1)(iv) of the Developer’s Partnership Agreement, may be increased to a competitive rate as determined by the Managing General Partner.

The estimated price for drilling and completing each of the wells shall be set forth in an Authority for Expenditure (“AFE”) that shall be attached to this Agreement as an Exhibit, and shall cover all ordinary costs which may be incurred in drilling and completing (or plugging) each well. This includes without limitation, site preparation, permits and bonds, roadways, surface damages, power at the site, water, Operator’s compensation as set forth above, rights-of-way, drilling rigs, equipment and materials, costs of title examinations, logging, cementing, fracturing, casing, meters (other than utility purchase meters), connection facilities, salt water collection tanks, separators, siphon string, rabbit, tubing, an average of 2,500 feet of gathering line per well in connection with each gas well, and geological, geophysical and engineering services.

After each intangible well or additional well is drilled and completed under this Agreement, on request Operator shall prepare and deliver to the Developer an amended AFE that sets forth the allocation between Intangible Drilling Costs and Tangible Costs (as those terms are defined in Section 4(b), below, for the well based on the actual costs to drill and complete the well.

(b) Payment. The Developer shall pay to Operator, in proportion to the share of the Working Interest owned by the Developer in the wells, one hundred percent (100%) of the estimated IDCs and Tangible Costs, as those terms are defined below, for drilling and completing all initial wells on execution of this Agreement. Notwithstanding the foregoing, Atlas’ payments for its share of the estimated Tangible Costs, as that term is defined below, of drilling and completing all initial wells as the Managing General Partner of the Developer shall be paid within five (5) business days of notice from Operator that the costs have been incurred. The Developer’s payment shall be nonrefundable in all events in order to enable Operator to do the following:

(i) commence site preparation for the initial wells;

(ii) obtain suitable subcontractors for drilling and completing or plugging the initial wells at currently prevailing prices; and

(iii) insure the availability of equipment and materials.

For purposes of this Agreement, “Intangible Drilling Costs” or “IDCs” shall mean those expenditures associated with property acquisition and the drilling and completion of oil and gas wells that under present law are generally accepted as fully deductible currently for federal income tax purposes. This includes:

(i) all expenditures made with respect to any well before the establishment of production in commercial quantities for wages, fuel, repairs, hauling, supplies and other costs and expenses incident to and necessary for the drilling of the well and the preparation of the well for the production of oil or gas, that are currently deductible pursuant to Section 263(c) of the Internal Revenue Code of 1986, as amended (the “Code”), and Treasury Reg. Section 1.612-4, which are generally termed “intangible drilling and development costs”;

(ii) the expense of plugging and abandoning any well before a completion attempt; and

(iii) the costs (other than Tangible Costs and Lease acquisition costs) to re-enter and deepen an existing well, complete the well to deeper formations or reservoirs, or plug and abandon the well if it is nonproductive from the targeted deeper formations or reservoirs.

6

“Tangible Costs” shall mean those costs associated with property acquisition and the drilling and completion of oil and gas wells that are generally accepted as capital expenditures pursuant to the provisions of the Code. This includes:

(i) all costs of equipment, parts and items of hardware used in drilling and completing (or plugging) a well;

(ii) the costs (other than IDCs and Lease acquisition costs) to re-enter and deepen an existing well, complete the well to deeper formations or reservoirs, or plug and abandon the well if it is nonproductive from the targeted deeper formations or reservoirs; and

(iii) those items necessary to deliver acceptable oil and gas production to purchasers to the extent installed downstream from the wellhead of any well, which are required to be capitalized under the Code and its regulations.

With respect to each additional well drilled on the Additional Well Locations, if any, the Developer shall pay to Operator, in proportion to the share of the Working Interest owned by the Developer in the wells, one hundred percent (100%) of the estimated IDCs and Tangible Costs for drilling and completing the well on execution of the applicable addendum pursuant to Section l(c) above. Notwithstanding the foregoing, Atlas’ payments for its share of the estimated Tangible Costs of drilling and completing all additional wells as the Managing General Partner of the Developer shall be paid within five (5) business days of notice from Operator that the costs have been incurred.

The Developer’s payment shall be nonrefundable in all events in order to enable Operator to do the following:

(i) commence site preparation for the additional wells;

(ii) obtain suitable subcontractors for drilling and completing the additional wells at currently prevailing prices; and

(iii) insure the availability of equipment and materials.

Developer shall pay, in proportion to the share of the Working Interest owned by the Developer in the wells, any extra costs incurred for each well pursuant to sub-section (a) above within ten (10) business days of its receipt of Operator’s statement for the extra costs.

(c) Completion Determination. Operator shall determine whether or not to run the production casing for an attempted completion or to plug and abandon any well drilled under this Agreement. However, a well shall be completed only if Operator has made a good faith determination that there is a reasonable possibility of obtaining commercial quantities of oil and/or gas.

(d) Dry Hole Determination. If Operator determines at any time during the drilling or attempted completion of any well drilled under this Agreement, in accordance with the generally accepted and customary oil and gas field practices and techniques then prevailing in the geographic area of the Well Location that the well should not be completed, then it shall promptly and properly plug and abandon the well.

(e) Excess Funds and Cost Overruns-Intangible Drilling Costs. Any estimated IDCs (which are the IDCs set forth on the AFE Exhibit) prepaid by Developer with respect to any well that exceed Operator’s price specified in sub-section (a) above for the Intangible Drilling Costs of the well (i.e., the actual IDCs) shall be retained by Operator. This excess of estimated IDCs as reflected on the AFE Exhibit over the actual price of the IDCs for the well shall be applied, in proportion to the share of the Working Interest owned by the Developer in the wells, to:

(i) the IDCs of an additional well or wells to be drilled on the Additional Well Locations; or

7

(ii) any cost overruns owed by the Developer to Operator for IDCs on one or more of the other wells on the Well Locations.

Conversely, if Operator’s price specified in sub-section (a) above for the IDCs of any well (i.e., the actual IDCs) exceeds the estimated IDCs (which are the IDCs set forth on the AFE Exhibit) prepaid by Developer for the well, then:

(i) Developer shall pay the additional price to Operator within ten (10) business days after notice from Operator that the additional amount is due and owing; or

(ii) Developer and Operator may agree to delete or reduce Developer’s Working Interest in the well or one or more of the other wells to be drilled under this Agreement to provide funds to pay the additional amounts owed by Developer to Operator. If doing so results in any excess prepaid IDCs, then these funds shall be applied, in proportion to the share of the Working Interest owned by the Developer in the wells, to:

(a) the IDCs of an additional well or wells to be drilled on the Additional Well Locations; or

(b) any cost overruns owed by the Developer to Operator for IDCs of one or more of the other wells on the Well Locations.

The Exhibits to this Agreement with respect to the affected wells shall be amended as appropriate.

(f) Excess Funds and Cost Overruns — Tangible Costs. Any estimated Tangible Costs (which are the Tangible Costs set forth on the AFE Exhibit) prepaid by Developer with respect to any well that exceed Operator’s price specified in sub-section (a) above for the Tangible Costs of the well (i.e., the actual Tangible Costs) shall be retained by Operator. This excess of Tangible Costs as reflected on the AFE Exhibit over the actual price of the Tangible Costs for the well shall be applied, in proportion to the share of the Working Interest owned by the Developer in the wells, to:

(i) the Developer’s Participants’ share of the Tangible Costs for an additional well or wells to be drilled on the Additional Well Locations; or

(ii) any cost overruns owed by the Developer to Operator for the Developer’s Participants’ share of the Tangible Costs or Intangible Drilling Costs of one or more of the other wells on the Well Locations.

Conversely, if Operator’s price specified in sub-section (a) above for the Developer’s Participants’ share of Tangible Costs of any well (i.e., the actual Tangible Costs) exceeds the estimated Tangible Costs (which are the Tangible Costs set forth on the AFE Exhibit) prepaid by Developer for the Developer’s Participants’ share of the Tangible Costs for the well, then:

(i) Developer shall pay the additional price to Operator within ten (10) business days after notice from Operator that the additional price is due and owing; or

(ii) Developer and Operator may agree to delete or reduce Developer’s Working Interest in the well or one or more of the other wells to be drilled under this Agreement to provide funds to pay the additional amounts owed by Developer to Operator. If doing so results in any excess prepaid Tangible Costs, then these funds shall be applied, in proportion to the share of the Working Interest owned by the Developer in the wells, to:

(a) the Developer’s Participants’ share of the Tangible Costs of an additional well or wells to be drilled on the Additional Well Locations; or

(b) any cost overruns owed by the Developer to Operator for the Developer’s Participants’ share of the Tangible Costs or Intangible Drilling Costs of one or more of the other wells on the Well Locations.

8

(iii) The Developer’s Participants’ share of the Tangible Costs, in the aggregate, of all of the wells drilled under this Agreement and any additional wells to be drilled on the Additional Well Locations under any Addendum to this Agreement shall not exceed fifteen percent (15%) of the total price prepaid by Developer to Operator pursuant to Section 4(b) of this Agreement or any Addendum hereto. The Developer’s Managing General Partner shall pay all remaining Tangible Costs owed by Developer to Operator. Developer’s Managing General Partner’s share of Tangible Costs for the wells drilled under this Agreement, or any Addendum hereto, shall be paid within five (5) business days of notice from Operator that the Tangible Costs have been incurred. The Developer’s Participants’ share of the Tangible Costs of any one well drilled under this Agreement shall be determined, subject to the preceding sentence, taking into account the Developer’s share of all of the Tangible Costs of all of the wells to be drilled under this Agreement and any Addendum hereto.

The Exhibits to this Agreement with respect to the affected wells shall be amended as appropriate.

5. Title Examination of Well Locations; Developer’s Acceptance and Liability; Additional Well Locations.

(a) Title Examination of Well Locations, Developer’s Acceptance and Liability. The Developer acknowledges that Operator has furnished Developer with the title opinions identified on Exhibit A, and other documents and information that Developer or its counsel has requested in order to determine the adequacy of the title to the Initial Well Locations and leased premises subject to this Agreement. The Developer accepts the title to the Initial Well Locations and leased premises and acknowledges and agrees that, except for any loss, expense, cost, or liability caused by the breach of any of the warranties and representations made by the Operator in Section l(b), any loss, expense, cost or liability whatsoever caused by or related to any defect or failure of the Developer’s title shall be the sole responsibility of and shall be borne entirely by the Developer.

(b) Additional Well Locations. Before beginning drilling of any well on any Additional Well Location, Operator shall conduct, or cause to be conducted, a title examination of the Additional Well Location, in order to obtain appropriate abstracts, opinions and certificates and other information necessary to determine the adequacy of title to both the applicable Lease and the fee title of the lessor to the premises covered by the Lease. The results of the title examination and such other information as is necessary to determine the adequacy of title for drilling purposes shall be submitted to the Developer for its review and acceptance. No drilling on the Additional Well Location shall begin until the title has been accepted in writing by the Developer or Developer has otherwise authorized the drilling on the Additional Well Location. After any title has been accepted by the Developer or drilling on the Additional Well Location has begun, any loss, expense, cost, or liability whatsoever, caused by or related to any defect or failure of the Developer’s title shall be the sole responsibility of and shall be borne entirely by the Developer, unless such loss, expense, cost, or liability was caused by the breach of any of the warranties and representations made by the Operator in Section l(b).

6. Operations Subsequent to Completion of the Wells; Fee Adjustments; Extraordinary Costs; Pipelines; Price Determinations; Plugging and Abandonment.

(a) Operations Subsequent to Completion of the Wells. Beginning with the month in which a well drilled under this Agreement begins to produce, Operator shall be entitled to an operating fee at a competitive rate in the area where the well is situated, which is $975 per month for each productive well in the Marcellus Shale in western Pennsylvania and $1,500 per month for each productive well in the New Albany Shale in Indiana. The operating fees shall be proportionately reduced, on a well-by-well basis to the extent the Developer owns less than 100% of the Working Interest in a well. This fee shall be in lieu of any direct charges by Operator for its services or the provision by Operator of its equipment for normal superintendence and maintenance of the wells and related pipelines and facilities.

9

The operating fees shall cover all normal, regularly recurring operating expenses for the production, delivery and sale of natural gas, including without limitation:

(i)	well tending, routine maintenance and adjustment;
(ii)	reading meters, recording production, pumping, maintaining appropriate books and records;
(iii)	preparing reports to the Developer and government agencies; and
(iv)	collecting and disbursing revenues.

The operating fees shall not cover costs and expenses related to the following:

(i)	the production and sale of oil;
(ii)	the collection and disposal of salt water or other liquids produced by the wells;
(iii)	the rebuilding of access roads; and
(iv)	the purchase of equipment, materials or third party services;

which, subject to the provisions of sub-section (c) of this Section 6, shall be invoiced by Operator to the Developer on a monthly basis, and shall be paid by the Developer within ten (10) business days after notice from Operator that the additional amounts are due and owing in proportion to the share of the Working Interest owned by the Developer in the wells.

Any well that is temporarily abandoned or shut-in continuously for an entire calendar month shall not be considered a producing well for purposes of determining the number of wells in the month subject to the operating fee.

(b) Fee Adjustments. The monthly operating fee set forth in sub-section (a) above may be adjusted by Operator annually, as of the first day of January (the “Adjustment Date”) of each year, beginning January 1, 2011. This adjustment, if any, shall not exceed the percentage increase in the average weekly earnings of “Crude Petroleum, Natural Gas, and Natural Gas Liquids” workers, as published by the U.S. Department of Labor, Bureau of Labor Statistics, and shown in Employment and Earnings Publication, Monthly Establishment Data, Hours and Earning Statistical Table C-2, Index Average Weekly Earnings of “Crude Petroleum, Natural Gas, and Natural Gas Liquids” workers, SIC Code #131-2, or any successor index thereto, since January l, 2010, in the case of the first adjustment, and since the previous Adjustment Date, in the case of each subsequent adjustment.

In addition, the monthly operating fee set forth in sub-section (a) above for any given well or wells being operated under this Agreement may be increased beyond the annual adjustment described in the prior paragraph without advance notice to the Developer, from time-to-time, to the competitive rate in the area where the well(s) are situated, as determined by the Operator in its sole discretion.

(c) Extraordinary Costs. Without the prior written consent of the Developer, pursuant to a written estimate submitted by Operator, Operator shall not undertake any single project or incur any extraordinary cost with respect to any well being produced under this Agreement that is reasonably estimated to result in an expenditure of more than $5,000, unless the project or extraordinary cost is necessary for the following:

(i) to safeguard persons or property; or

(ii) to protect the well or related facilities in the event of a sudden emergency.

10

In no event, however, shall the Developer be required to pay for any project or extraordinary cost arising from the negligence or misconduct of Operator, its agents, servants, employees, subcontractors, licensees, or invitees.

All extraordinary costs incurred and the cost of projects undertaken under this section with respect to a well being produced under this Agreement shall be billed to the Developer at the invoice cost of third-party services performed or materials purchased together with a reasonable and competitive charge by Operator for any services performed directly by it, in proportion to the share of the Working Interest owned by the Developer in the well. Operator shall have the right to require the Developer to pay in advance all or a portion of the estimated costs of a project undertaken under this section, before undertaking the project, in proportion to the share of the Working Interest owned by the Developer in the well or wells.

(d) Pipelines. Subject to Sections 2 (d) and 4 (a) relating to Developer’s interest in gathering lines for the wells, Developer shall have no interest in any natural gas pipeline and gathering system or processing plant, including but not limited to gathering system’s owned by the Operator or its Affiliates, including Laurel Mountain Midstream, LLC’s gathering system and processing plants in Indiana in which an affiliate of the Developer owns an interest. Also, Developer shall not be charged any cost or expense for the construction, expansion or maintenance of those pipeline and gathering systems or processing plants.

(e) Price Determinations. Notwithstanding anything in this Agreement to the contrary, the Developer shall pay all costs in proportion to the share of the Working Interest owned by the Developer in the wells with respect to obtaining price determinations under and otherwise complying with the Natural Gas Policy Act of 1978 and the implementing state regulations. This responsibility shall include, without limitation, preparing, filing, and executing all applications, affidavits, interim collection notices, reports and other documents necessary or appropriate to obtain price certification, to effect sales of natural gas, or otherwise to comply with the Act and the implementing state regulations.

Operator agrees to furnish the information and render the assistance as the Developer may reasonably request in order to comply with the Act and the implementing state regulations without charge for services performed by its employees.

(f) Plugging and Abandonment. The Developer shall have the right to direct Operator to plug and abandon any well that has been completed under this Agreement as a producer. In addition, Operator shall not plug and abandon any well that has been drilled and completed as a producer under this Agreement before obtaining the written consent of the Developer. However, if the Operator determines that any well drilled and completed under this Agreement as a producer shall be plugged and abandoned in accordance with the generally accepted and customary oil and gas field practices and techniques then prevailing in the geographic area of the well location, and makes a written request to the Developer for authority to plug and abandon the well and the Developer fails to respond in writing to the request within forty-five (45) days following the date of the request, then the Developer shall be deemed to have consented to the plugging and abandonment of the well.

All costs and expenses related to plugging and abandoning wells that have been drilled and completed under this Agreement as producing wells shall be borne and paid by the Developer in proportion to the share of the Working Interest owned by the Developer in the wells. Also, at any time after one (1) year from the date each well drilled and completed under this Agreement is placed into production, Operator shall have the right to deduct each month from the proceeds of the sale of the production from the well up to $200, in proportion to the share of the Working Interest owned by the Developer in the well, for the purpose of establishing a fund to cover the Operator’s estimate of the Developer’s share of the costs of eventually plugging and abandoning the well. All of these funds shall be deposited by Operator in a separate interest bearing escrow account for the account of the Developer, and the total amount so retained and deposited shall not exceed Operator’s reasonable estimate of Developer’s share of the costs of eventually plugging and abandoning the well.

11

However, without the prior written consent of the Developer, the Operator may not assign, transfer, pledge, mortgage, hypothecate, sell or otherwise dispose of any of its interest in this Agreement, or any of its rights or obligations under this Agreement. Notwithstanding, this consent shall not be required in connection with:

(i) the assignment of work to be performed for Operator to subcontractors, it being understood and agreed, however, that any assignment to Operator’s subcontractors shall not in any manner relieve or release Operator from any of its obligations and responsibilities under this Agreement;

(ii) any lien, assignment, security interest, pledge or mortgage arising under Operator’s present or future financing arrangements; or

(iii) the liquidation, merger, consolidation, or other corporate reorganization or sale of substantially all of the assets of Operator.

Further, in order to maintain uniformity of ownership in the wells, production, equipment, and leasehold interests covered by this Agreement, and notwithstanding any other provision of this Agreement to the contrary, the Developer shall not, without the prior written consent of Operator, sell, assign, transfer, encumber, mortgage or otherwise dispose of any of its interest in the wells, production, equipment or leasehold interests covered by this Agreement unless the disposition encompasses either:

(i) the entire interest of the Developer in all wells, production, equipment and leasehold interests subject to this Agreement; or

(ii) an equal undivided interest in all such wells, production, equipment, and leasehold interests.

(b) Transfers. Subject to the provisions of sub-section (a) above, any sale, encumbrance, transfer or other disposition made by the Developer of its interests in the wells, production, equipment, and/or leasehold interests covered by this Agreement shall be made:

(i)	expressly subject to this Agreement;
(ii)	without prejudice to the rights of the Operator; and
(iii)	in accordance with and subject to the provisions of the Leases covering the Well Locations.

(c) Appointment of Agent. If at any time the interest of the Developer is divided among or owned by co-owners, Operator may, in its discretion, require the co-owners to appoint a single trustee or agent with full authority to do the following:

(i)	receive notices, reports and distributions of the proceeds from production;
(ii)	approve expenditures;

(iii) receive billings for and approve and pay all costs, expenses and liabilities incurred under this Agreement;

(iv) exercise any rights granted to the co-owners under this Agreement;

14

(v) grant any approvals or authorizations required or contemplated by this Agreement;

(vi) sign, execute, certify, acknowledge, file and/or record any agreements, contracts, instruments, reports, or documents whatsoever in connection with this Agreement or the activities contemplated by this Agreement; and

(vii) deal generally with, and with power to bind, the co-owners with respect to all activities and operations contemplated by this Agreement.

However, all the co-owners shall continue to have the right to enter into and execute all contracts or agreements for their respective shares of the oil and gas produced from the wells drilled under this Agreement in accordance with sub-section (c) of Section 11.

10. Operator’s Insurance; Subcontractors’ Insurance; Operator’s Liability.

(a) Operator’s Insurance. Operator shall obtain and maintain at its own expense so long as it is Operator under this Agreement all required Workmen’s Compensation Insurance and comprehensive general public liability insurance in amounts and coverage not less than $1,000,000 per person per occurrence for personal injury or death and $1,000,000 for property damage per occurrence, which shall include coverage for blow-outs, and total liability coverage of not less than $10,000,000.

Subject to the above limits, the Operator’s general public liability insurance shall be in all respects comparable to that generally maintained in the industry with respect to services of the type to be rendered and activities of the type to be conducted under this Agreement. Operator’s general public liability insurance shall, if permitted by Operator’s insurance carrier:

(i) name the Developer as an additional insured party; and

(ii) provide that at least thirty (30) days’ prior notice of cancellation and any other adverse material change in the policy shall be given to the Developer.

However, the Developer shall reimburse Operator for the additional cost, if any, of including it as an additional insured party under the Operator’s insurance.

Current copies of all policies or certificates of the Operator’s insurance coverage shall be delivered to the Developer on request. It is understood and agreed that Operator’s insurance coverage may not adequately protect the interests of the Developer and that the Developer shall carry at its expense the excess or additional general public liability, property damage, and other insurance, if any, as the Developer deems appropriate.

(b) Subcontractors’ Insurance. Operator shall require all of its subcontractors to carry all required Workmen’s Compensation Insurance and to maintain such other insurance, if any, as Operator in its discretion may require.

(c) Operator’s Liability. Operator’s liability to the Developer as Operator under this Agreement shall be limited to, and Operator shall indemnify the Developer and hold it harmless from, claims, penalties, liabilities, obligations, charges, losses, costs, damages, or expenses (including but not limited to reasonable attorneys’ fees) as provided in Section 4.05 of the Developer’s Partnership Agreement.

11. Internal Revenue Code Election; Relationship of Parties; Right to Take Production in Kind.

(a) Internal Revenue Code Election. With respect to this Agreement, each of the parties elects under Section 761(a) of the Internal Revenue Code of 1986, as amended, to be excluded from the provisions of Subchapter K of Chapter 1 of Subtitle A of the Internal Revenue Code of 1986, as amended. If the income tax laws of the state or states in which the property covered by this Agreement is located contain, or may subsequently contain, a similar election, each of the parties agrees that the election shall be exercised.

15

Beginning with the first taxable year of operations under this Agreement, each party agrees that the deemed election provided by Section 1.761-2(b)(2)(ii) of the Regulations under the Internal Revenue Code of 1986, as amended, will apply; and no party will file an application under Section 1.761-2 (b)(3)(i) of the Regulations to revoke the election. Each party agrees to execute the documents and make the filings with the appropriate governmental authorities as may be necessary to effect the election.

(b) Relationship of Parties. It is not the intention of the parties to create, nor shall this Agreement be construed as creating, a mining or other partnership or association or to render the parties liable as partners or joint venturers for any purpose. Operator shall be deemed to be an independent contractor and shall perform its obligations as set forth in this Agreement.

(c) Right to Take Production in Kind. Subject to the provisions of Section 8 above, the Developer shall have the exclusive right to sell or dispose of its proportionate share of all oil and gas produced from the wells to be drilled under this Agreement, exclusive of production:

(i)	that may be used in development and producing operations;
(ii)	unavoidably lost; and
(iii)	used to fulfill any free gas obligations under the terms of the applicable Lease or Leases.

Operator shall not have any right to sell or otherwise dispose of the oil and gas. The Developer shall have the exclusive right to execute all contracts relating to the sale or disposition of its proportionate share of the production from the wells drilled under this Agreement.

Developer shall have no interest in any gas supply agreements of Operator, except the right to receive Developer’s share of the proceeds received from the sale of any gas or oil from wells developed under this Agreement. The Developer agrees to designate Operator or Operator’s designated bank agent as the Developer’s collection agent in any contracts. On request, Operator shall assist Developer in arranging the sale or disposition of Developer’s oil and gas under this Agreement and shall promptly provide the Developer with all relevant information that comes to Operator’s attention regarding opportunities for selling production.

If Developer fails to take in kind or separately dispose of its proportionate share of the oil and gas produced under this Agreement, then Operator shall have the right, subject to the revocation at will by the Developer, but not the obligation, to purchase the oil and gas or sell it to others at any time and from time to time, for the account of the Developer at the best price obtainable in the area for the production. Notwithstanding, Operator shall have no liability to Developer should Operator fail to market the production.

Any such purchase or sale by Operator shall be subject always to the right of the Developer to exercise at any time its right to take in-kind, or separately dispose of, its share of oil and gas not previously delivered to a purchaser. Any purchase or sale by Operator of the Developer’s share of oil and gas under this Agreement shall be only for reasonable periods of time as are consistent with the minimum needs of the oil and gas industry under the particular circumstances, but in no event for a period in excess of one (1) year.

12. Effect of Force Majeure; Definition of Force Majeure; Limitation.

(a) Effect of Force Majeure. If Operator is rendered unable, wholly or in part, by force majeure (as defined below) to carry out any of its obligations under this Agreement, including but not limited to beginning the drilling of one or more wells by the applicable times set forth in Section 2(b), or any Addendum to this Agreement, the obligations of the Operator, so far as it is affected by the force majeure, shall be suspended during but no longer than, the continuance of the force majeure. The Operator shall give to the Developer prompt written notice of the force majeure with reasonably full particulars concerning it. Operator shall use all reasonable diligence to remove the force majeure as quickly as possible to the extent the same is within its reasonable control.

16

(b) Definition of Force Majeure. The term “force majeure” shall mean an act of God, strike, lockout, or other industrial disturbance, act of the public enemy, war, terrorist acts, blockade, public riot, lightning, fire, storm, flood, explosion, governmental restraint, unavailability of drilling rigs, equipment or materials, plant shut-downs, curtailments by oil and gas purchasers and any other causes whether of the kind specifically enumerated above or otherwise, which directly preclude Operator’s performance under this Agreement and are not reasonably within the control of the Operator including, but not limited to, the inability of Operator to begin the drilling of the wells subject to this Agreement by the applicable times set forth in Section 2(b) or in any Addendum to this Agreement due to decisions of third-party operators to delay drilling the wells, poor weather conditions, inability to obtain drilling permits, access rights to the drilling site or title problems.

(c) Limitation. The requirement that any force majeure shall be remedied with all reasonable dispatch shall not require the settlement of strikes, lockouts, or other labor difficulty affecting the Operator contrary to its wishes. The method of handling these difficulties shall be entirely within the discretion of the Operator.

13. Term.

This Agreement shall become effective when executed by Operator and the Developer. Except as provided in sub-section (c) of Section 3, this Agreement shall continue and remain in full force and effect for the productive lives of each well being operated under this Agreement.

14. Governing Law; Invalidity.

(a) Governing Law. This Agreement shall be governed by, construed and interpreted in accordance with the laws of the Commonwealth of Pennsylvania, excluding its conflict of law provisions.

(b) Invalidity. The invalidity or unenforceability of any particular provision of this Agreement shall not affect the other provisions of this Agreement, and this Agreement shall be construed in all respects as if the invalid or unenforceable provision were omitted.

15. Integration; Written Amendment.

(a) Integration. This Agreement, including the Exhibits to this Agreement, constitutes and represents the entire understanding and agreement of the parties with respect to the subject matter of this Agreement and supersedes all prior negotiations, understandings, agreements, and representations relating to the subject matter of this Agreement.

(b) Written Amendment. No change, waiver, modification, or amendment of this Agreement shall be binding or of any effect unless in writing duly signed by the party against which the change, waiver, modification, or amendment is sought to be enforced.

16. Waiver of Default or Breach.

No waiver by any party to any default of or breach by any other party under this Agreement shall operate as a waiver of any future default or breach, whether of like or different character or nature.

17

17. Notices.

Unless otherwise provided in this Agreement, all notices, statements, requests, or demands that are required or contemplated by this Agreement shall be in writing and shall be hand-delivered or sent by registered or certified mail, postage prepaid, to the following addresses until a party’s address is changed by certified or registered letter so addressed to the other party:
