NOTE 1 — DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

Atlas America Series 26-2005 L.P. (the “Partnership”) is a Delaware Limited Partnership which includes Atlas Resources, LLC of Pittsburgh, Pennsylvania, as Managing General Partner (“MGP”) and Operator, and 588 Limited Partners. The Partnership was formed on May 26, 2005 to drill and operate gas wells located primarily in Pennsylvania and Tennessee.

In March 2006, Atlas Resources, Inc. merged into a newly-formed limited liability company, Atlas Resources, LLC, which became an indirect subsidiary of Atlas Energy Resources, LLC, a newly-formed subsidiary of Atlas America, Inc. In December 2006, Atlas America, Inc. contributed substantially all of its natural gas and oil assets and its investment partnership management business to Atlas Energy Resources, LLC. On September 29, 2009 Atlas Energy Resources, LLC and Atlas America, Inc. merged, with Atlas Energy Resources, LLC becoming a wholly owned subsidiary of Atlas America, Inc. In addition, Atlas America, Inc. changed its name to Atlas Energy, Inc, (NASDAQ: ATLS). Atlas Resources, LLC serves as the Partnership’s MGP.

The accompanying financial statements, which are unaudited except that the balance sheet at December 31, 2009, 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 Form 10-K. 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. 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, 2009. The results of operations for the three months ended March 31, 2010 may not necessarily be indicative of the results of operation for the year ended December 31, 2010.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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, 2009 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 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 three months ended March 31, 2010 represent actual results in all material respects (see “Revenue Recognition” accounting policy for further description).

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Accounts Receivable and Allowance for Possible Losses

In evaluating the need for an allowance for possible losses, the Partnership’s 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 March 31, 2010 and December 31, 2009, the Partnership’s MGP’s credit evaluation indicated that the Partnership had no need for an allowance for possible losses.

Revenue Recognition

The Partnership’s natural gas and oil is sold under various contracts entered into by its MGP. 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 MGP’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 records and estimates of the related commodity sales and transportation and compression fees which are, in turn, based upon applicable product prices. The Partnership had unbilled revenues at March 31, 2010 and December 31, 2009 of $383,800 and $429,600, respectively, which are included in accounts receivable-affiliate within the Partnership’s Balance Sheets.

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, 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 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.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Impairment of Long-Lived Assets (Continued)

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.

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, (“the working interest”). The MGP is also provided an additional working interest of 7% 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.

Oil and Gas Properties

The Partnership follows the successful-efforts method of accounting for oil and gas producing activities. Oil and gas properties are recorded at cost. Depletion is determined on a field-by-field basis using the units-of-production method for well and related equipment costs 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. In addition, accumulated depletion includes impairment adjustments to reflect the write-down to fair market value of the oil and gas properties. Maintenance and repairs are expensed as incurred. Major renewals and improvements that extend the useful lives of the property are capitalized. The Partnership is required to consider estimated salvage value in the calculation of depletion. Oil and gas properties consist of the following at the dates indicated:


	March 31,			December 31,
	2010			2009
Natural gas and oil properties:

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Oil and Gas Properties (Continued)

The Partnership’s long-lived assets are reviewed for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Long-lived assets are reviewed for potential impairments at the lowest levels for which there are identifiable cash flows.

Upon the sale or retirement of a complete or partial unit of a proved property, the cost is eliminated from the property accounts, and the resultant gain or loss is reclassified to accumulated depletion. Upon the sale of an entire interest where the property had been assessed for impairment, a gain or loss is recognized in the Statement of Operations. As a result of retirements the Partnership reclassified $339,800, for the three months ended March 31, 2010 which includes well costs of $345,300 and proceeds from sale of tangible equipment of $5,500 from oil and gas properties, to accumulated depletion.

Recently Adopted Accounting Standards

In January 2010, the FASB issued Accounting Standards Update 2010-02, “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 Partnership applied the requirements of Update 2010-06 upon its adoption on January 1, 2010, and it did not have a material impact on its financial position, results of operations or related disclosures.

NOTE 3 — TRANSACTIONS WITH ATLAS RESOURCES, LLC AND ITS AFFILIATES

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

	•		Administrative costs which are included in general and administrative expenses in the Partnership’s Statements of Operations are payable at $75 per well per month. Administrative costs incurred for the three months ended March 31, 2010 and 2009 were $27,300 and $27,600, respectively.

	•		Monthly well supervision fees which are included in production expenses in the Partnership’s Statements of Operations are payable at $318 per well per month in 2010 and 2009, for operating and maintaining the wells. Well supervision fees incurred for the three months ended March 31, 2010 and 2009 were $114,000 and $115,600, respectively.

	•		Transportation fees which are included in production expenses in the Partnership’s Statements of Operations are generally payable at 13% of the natural gas sales price. Transportation fees incurred for the three months ended March 31, 2010 and 2009 were $81,600 and $109,900, respectively.

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.

NOTE 3 — TRANSACTIONS WITH ATLAS RESOURCES, LLC AND ITS AFFILIATES (Continued)

Subordination by Managing General Partner

Under the terms of the Partnership agreement, the MGP may be required to subordinate up to 50% of its share of production revenues of the Partnership to the benefit of the limited partners for an amount equal to at least 10% of their net subscriptions, determined on a cumulative basis, in each of the first five years of Partnership operations, commencing with the first distribution to the investor partners (September 2006) and expiring 60 months from that date. For the three months ended March 31, 2010, the MGP was required to subordinate $24,900 of its net production of $49,800. Therefore MGP capital was decreased and the limited partners capital was increased by $24,900 as shown on the Statement of Changes in Partners’ Capital for the three months ended March 31, 2010.

NOTE 4 — COMPREHENSIVE INCOME (LOSS)

Comprehensive income (loss) includes net (loss) earnings 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, have not been recognized in the calculation of net (loss) earnings. These changes, other than net (loss) earnings, are referred to as “other comprehensive income (loss)” and, for the Partnership, include changes in the fair value of unsettled derivative contracts accounted for as cash flow hedge. A reconciliation of the Partnership’s comprehensive income (loss) for the periods indicated is as follows:


	Three Months Ended
	March 31,
	2010			2009
Net (loss) earnings	$	(6,900	)	$	149,600

Comprehensive income (loss)	$	483,500		$	(7,000	)

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)

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 Partnership 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 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 will reclassify commodity derivatives to gas and oil production revenues in 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. The following table summarizes the fair value of derivative instruments as of March 31, 2010 and December 31, 2009, as well as the gain or loss on the derivative instruments as of March 31, 2010 and 2009, respectively.

At any point in time, such contracts may include regulated New York Mercantile Exchange (“NYMEX”) futures, options contracts and non-regulated over-the-counter futures contracts with qualified counterparties. NYMEX contracts are generally settled with offsetting positions, but may be settled by the delivery of natural gas. 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.

NOTE 5 — DERIVATIVE INSTRUMENTS (Continued)

At March 31, 2010, the Partnership reflected a net hedge asset on our Balance Sheets of $1,091,300, however unrealized gains of $549,300 recognized in income results in a net accumulated other comprehensive income balance of $542,000. The unrealized gain of $549,300 is from 2008 impairments. Of the remaining $542,000 net unrealized gain in accumulated other comprehensive income at March 31, 2010, if the fair values of the instruments remain at current market values, the Partnership will reclassify $377,500 of net gains to its Statements of Operations over the next twelve month period as these contracts settle, and $164,500 of net gains in later periods. Actual amounts that will be reclassified will vary as a result of future price changes. Ineffective hedge gains or losses are recorded within the Statements of Operations while the hedge contract is open and may increase or decrease until settlement of the contract.

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

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

NOTE 6 — FAIR VALUE OF FINANCIAL INSTRUMENTS (Continued)

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 5). The Partnership’s 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. Assets and Liabilities measured at fair value at March 31, 2010 and December 31, 2009 were as follows.


	March 31, 2010				December 31, 2009
	Level 2		Total		Level 2		Total

Commodity-based derivatives	$	1,091,300	$	1,091,300	$	664,000	$	664,000

Total	$	1,091,300	$	1,091,300	$	664,000	$	664,000

Assets and Liabilities Measured at Fair Value on a Nonrecurring 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: amount and timing of settlements; the risk-free rate of the Partnership; and estimated inflation rates (see Note 7).

The Partnership’s long-lived assets are reviewed for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the carrying value exceeds such undiscounted cash flows, an impairment loss is recognized for the difference between the estimated fair market value and the carrying value of the assets.

NOTE 7 — ASSET RETIREMENT OBLIGATION

The Partnership recognizes an estimated liability for the plugging and abandonment of its oil and gas wells. The associated asset retirement costs are capitalized as part of oil and gas properties. 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 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.

ITEM 2.		MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (UNAUDITED)

Forward-Looking Statements

When used in this Form 10-Q, the words “believes,” “anticipates,” “expects” and similar expressions are intended to identify forward-looking statements. These risks and uncertainties could cause actual results to differ materially from the results stated or implied in this document. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof. We undertake no obligation to publicly release the results of any revisions to forward-looking statements which we may make to reflect events or circumstances after the date of this Form 10-Q or to reflect the occurrence of unanticipated events.

Management’s Discussion and Analysis should be read in conjunction with our Financial Statements and the Notes to our Financial Statements.

General

We were formed as a Delaware limited partnership on May 26, 2005, with Atlas Resources, Inc. as our Managing General Partner, or MGP, to drill natural development wells. Atlas Resources, Inc. was merged into a newly-formed limited liability company, Atlas Resources, LLC, which became an indirect subsidiary of Atlas America, Inc. Atlas Resources, LLC now serves as our MGP.

Our wells are currently producing natural gas and oil which are our only products. Most of our gas is gathered and delivered to market through Laurel Mountain Midstream, LLC’s gas gathering system, a newly formed joint-venture between Atlas Energy, Inc.’s affiliate Atlas Pipeline Partners L.P. (NYSE: APL) and The Williams Companies Inc. (NYSE: WMB). We do not plan to sell any of our wells and will continue to produce them until they are depleted or become uneconomical to produce, at which time they will be plugged and abandoned or sold. No other wells will be drilled and no additional funds will be required for drilling.

Results of Operations

The following table sets forth information relating to our production revenues, volumes, sales prices, production costs and depletion during the periods indicated:


	Three Months Ended
	March 31,
	2010			2009

Production revenues (in thousands):
Gas	$	605		$	708
Oil		31			62

Total	$	636		$	770

Production volumes:
Gas (mcf/day) ⁽¹⁾		1,094			1,176
Oil (bbls/day) ⁽¹⁾		6			18

Total (mcfe/day) ⁽¹⁾		1,130			1,284

Average sales prices: ⁽²⁾
Gas (per mcf) ^{(1) (3)}	$	6.74		$	9.24
Oil (per bbl) ^{(1) (4)}	$	69.34		$	45.29

Average production costs:
As a percent of revenues		43	%		38	%
Per mcfe ⁽¹⁾	$	2.72		$	2.52

Depletion per mcfe	$	3.00		$	2.34


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

(2)		Average sales prices represent accrual basis pricing after reversing the effect of previously recognized gains resulting from prior period impairment charges.

(3)		Average gas prices are calculated by including in total revenue derivative gains previously recognized into income and dividing by the total volume for the period. Previously recognized derivative losses were $58,400 and $269,200 for the three months ended March 31, 2010 and 2009, respectively. The derivative gains are included in other comprehensive income (loss) and resulted from prior period impairment charges.

(4)		Average oil prices are calculated by including in total revenue derivative gains previously recognized into income and dividing by the total volume for the period. Previously recognized derivative losses were $4,700 and $11,000 for the three months ended March 31, 2010 and 2009, respectively. The derivative gains are included in other comprehensive income (loss) and resulted from prior period impairment charges.

Natural Gas Revenues. Our natural gas revenues were $604,900 and $708,000 for the three months ended March 31, 2010 and 2009, respectively, a decrease of $103,100 (15%). The $103,100 decrease in natural gas revenues for the three months ended March 31, 2010 as compared to the prior year period was attributable to a $54,000 decrease in our natural gas sales prices after the effect of financial hedges and a $49,100 decrease in production volumes. Our production volumes decreased to 1,094 mcf per day for the three months ended March 31, 2010 from 1,176 mcf per day for the three months ended March 31, 2009, a decrease of 82 mcf per day (7%). The overall decrease in natural gas production volumes for the three months ended March 31, 2010 resulted primarily from the normal decline inherit in the life of a well.

Oil Revenues. We drill wells primarily to produce natural gas, rather than oil, but some wells have limited oil production. Our oil revenues were $30,600 and $62,300 for the three months ended March 31, 2010 and 2009, respectively, a decrease of $31,700 (51%). The $31,700 decrease in oil revenues for the three months ended March 31, 2010 as compared to the prior year similar period was attributable to a $42,700 decrease in production volumes which was partially offset by a $11,000 increase in oil prices after the effect of financial hedges. Our production volumes decreased to 6 bbls per day for the three months ended March 31, 2010 from 18 bbls per day for the three months ended March 31, 2009, a decrease of 12 bbls per day (67%).

Expenses. Production expenses were $276,200 and $291,600 for the three months ended March 31, 2010 and 2009, respectively, a decrease of $15,400 (5%). The decrease for the three months ended March 31, 2010 was primarily due to lower transportation fees and other variable expenses as compared to the prior year similar period.

Depletion of oil and gas properties as a percentage of oil and gas revenues were 48% and 35% in the three months ended March 31, 2010 and 2009, respectively. These percentage changes are directly attributable to changes in revenues, oil and gas reserve quantities, product prices, production volumes and changes in the depletable cost basis of our oil and gas properties.

General and administrative expenses for the three months ended March 31, 2010 and 2009 were $39,100 and $39,600, respectively a decrease of $500 (1%). These expenses include third-party costs for services as well as the monthly administrative fees charged by our MGP and services provided to us.

Liquidity and Capital Resources

Cash provided by operating activities decreased $430,200 in the three months ended March 31, 2010 to $444,900 as compared to $875,100 for the three months ended March 31, 2009. This decrease was primarily due to a decrease in net earnings before depletion, net non-cash loss on derivative value and accretion of $336,000. In addition, the change in accounts receivable-affiliate decreased operating cash flows by $80,700 in the three months ended March 31, 2010 as compared to the three months ended March 31, 2009.

Cash provided from investing activities for the three months ended March 31, 2010 was $5,500, for the sale of tangible equipment.

Cash used in financing activities decreased $477,900 during the three months ended March 31, 2010 to $417,900 from $895,800 for the three months ended March 31, 2009. This decrease was due to a decrease in cash distributions.

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

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

Critical Accounting Policies

The discussion and analysis of our financial condition and results of operations are based upon our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. On an on-going basis, we evaluate our estimates, including those related to asset retirement obligations, depletion and certain accrued receivables and liabilities. We base our estimates on historical experience and on various other assumptions that we believe reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. A discussion of our significant accounting policies we have adopted and followed in the preparation of our financial statements is included within “Notes to Financial Statements” in Part I, Item 1, “Financial Statements” in this quarterly report and in our Annual Report on Form 10-K for the year ended December 31, 2009.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

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

Under the supervision of our Chairman of the Board of Directors, Chief Executive Officer, President and Chief Financial Officer, we have carried out an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based upon that evaluation, our Chairman of the Board of Directors, Chief Executive Officer, President and Chief Financial Officer, concluded that, at March 31, 2010, our disclosure controls and procedures were effective at the reasonable assurance level.

There have been no changes in the Partnership’s internal control over financial reporting during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially effect, our internal control over financial reporting.

PART II OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS
