GLOSSARY OF CERTAIN TERMS

The following are definitions of certain significant terms used in this report. Other terms are defined in the text of this report.

“AMI” means the area of mutual interest, or AMI, consists of the Marcellus Shale formation in approximately 121 square miles of property located in Greene County, Pennsylvania in which ECA had leased approximately 9,300 acres and owned substantially all of the working interests at the date of formation of the Trust. ECA is obligated to drill the 52 development wells from drill sites on approximately 9,300 leased acres in the AMI. Until ECA has satisfied its drilling obligation, it will not be permitted to drill and complete any well in the Marcellus Shale formation within the AMI for its own account.

“Completion” (or its derivatives) means that the well has been perforated, stimulated, tested and permanent equipment for the production of natural gas has been installed.

“Dth” means one million British Thermal Units.

“Equivalent PUD Well” is defined as a well that is drilled horizontally in the Marcellus formation for a lateral distance of 2,500 feet measured from the midpoint of the curve to the end of the lateral multiplied by the working interest held by ECA. Wells with a horizontal lateral less than 2,500 feet will count as a fractional well in proportion to total lateral length divided by 2,500 feet. Wells with a horizontal lateral greater than 2,500 feet (subject to a maximum of 3,500 feet) will count as multiple fractions wells in proportion to the total lateral length divided by 2,500 feet.

“FASB ASC” means the Financial Accounting Standards Board Accounting Standards Codification.

“Gas” means natural gas and all other gaseous hydrocarbons, excluding condensate, butane, and other liquid and liquefiable components that are actually removed from the Gas stream by separation, processing, or other means.

“Incentive Threshold” means, for any particular quarter (through the first quarter of 2015), the amount shown in the column titled “Incentive Threshold” in the section titled “Overview” in Management’s Discussion and Analysis in this report. In exchange for agreeing to subordinate the 4,401,250 Trust units it owns, and in order to provide additional financial incentive to ECA to perform its drilling obligation and operations on the Underlying Properties in an efficient and cost-effective manner, ECA is entitled to receive incentive distributions equal to 50% of the amount by which the cash available for distribution on all of the Trust units in any quarter exceeds 150% of the subordination threshold for such quarter. ECA’s right to receive the incentive distributions will terminate upon the expiration of the subordination period.

“MMBtu” means one million British Thermal Units.

“Mcf” means one thousand standard cubic feet of natural gas.

“MMcf” means one million standard cubic feet of natural gas.

“Producing Wells” means the 14 natural gas wells located in Greene County, Pennsylvania and described as the “Producing Wells” in the Prospectus.

“Prospectus” means the final prospectus relating to the initial public offering of the Trust units as filed with the SEC pursuant to rule 424(b) on July 1, 2010.

“PUD Wells” means the horizontal natural gas development wells to be drilled by ECA to the Marcellus Shale formation within the “Area of Mutual Interest,” or “AMI”, described in the Prospectus and located in Greene

ECA MARCELLUS TRUST I

NOTES TO FINANCIAL STATEMENTS

(Unaudited)

NOTE 1. Organization of the Trust

ECA Marcellus Trust I is a Delaware statutory trust formed in March 2010 by Energy Corporation of America (“ECA”) to own royalty interests in fourteen producing horizontal natural gas wells producing from the Marcellus Shale formation, all of which are online and are located in Greene County, Pennsylvania (the “Producing Wells”) and royalty interests in 52 horizontal natural gas development wells to be drilled to the Marcellus Shale formation (the “PUD Wells”) within the “Area of Mutual Interest,” or “AMI”, comprised of approximately 9,300 acres held by ECA, of which it owns substantially all of the working interests, in Greene County, Pennsylvania. The effective date of the Trust was April 1, 2010; consequently, the Trust received the proceeds of production attributable to the PDP Royalty Interest from that date even though the PDP Royalty Interest was not conveyed to the Trust until the closing of the initial public offering on July 7, 2010. The total number of units the Trust is authorized to issue is 17,605,000 units, of which 13,203,750 are common units and 4,401,250 are subordinated units. The royalty interests were conveyed from ECA’s working interest in the Producing Wells and the PUD Wells limited to the Marcellus Shale formation (the “Underlying Properties”). The royalty interest in the Producing Wells (the “PDP Royalty Interest”) entitles the Trust to receive 90% of the proceeds (exclusive of any production or development costs but after deducting post-production costs and any applicable taxes) from the sale of production of natural gas attributable to ECA’s interest in the Producing Wells. The royalty interest in the PUD Wells (the “PUD Royalty Interest” and collectively with the PDP Royalty Interest, the “Royalty Interests”) entitles the Trust to receive 50% of the proceeds (exclusive of any production or development costs but after deducting post-production costs and any applicable taxes) from the sale of production of natural gas attributable to ECA’s interest in the PUD Wells. Approximately 50% of the estimated natural gas production attributable to the Trust’s royalty interests has been hedged with a combination of floors and swaps through March 31, 2014 (the “Hedge Arrangement”). The floor price contracts were transferred to the Trust by ECA, while ECA entered into a back-to-back swap agreement with the Trust to provide the Trust with the benefit of swap contracts entered into between ECA and third parties. ECA will be entitled to recoup the costs of establishing the floor price contracts only if and to the extent cash available for distribution by the Trust exceeds certain levels.

ECA is obligated to drill all of the PUD Wells by March 31, 2013; however, in the event of delays, ECA will have until March 31, 2014 to fulfill its drilling obligation. ECA has granted to the Trust a lien (the “Drilling Support Lien”) on ECA’s interest in the Marcellus Shale formation in the AMI (except the Producing Wells and any other wells which are already producing and not subject to the Royalty Interests) in order to secure the estimated amount of the drilling costs for the Trust’s interests in the PUD Wells. The amount obtained by the Trust pursuant to the Drilling Support Lien may not exceed $91 million. As ECA fulfills its drilling obligation over time, the total dollar amount that may be recovered will be proportionately reduced and the drilled PUD Wells will be released from the lien.

The Trust is not responsible for any costs related to the drilling of development wells or any other development or operating costs. The Trust’s cash receipts in respect of the royalties are determined after deducting post-production costs and any applicable taxes associated with the PDP and PUD Royalty Interests, and the Trust’s cash available for distribution includes cash receipts from its hedging contracts and is reduced by Trust administrative expenses and expenses incurred as a result of being a publicly traded entity. Post-production costs generally consist of costs incurred to gather, compress, transport, process, treat, dehydrate and market the natural gas produced. Any charge payable to ECA for such post-production costs on its Greene County Gathering System will be limited to $0.52 per MMBtu gathered until ECA has fulfilled its drilling obligation (the “Post-Production Services Fee”); thereafter, ECA may increase the Post-Production Services Fee to the extent necessary to recover certain capital expenditures in the Greene County Gathering System. Additionally, in the event that electric compression is utilized in lieu of gas used as fuel in the compression process, the Trust will be charged for the electric usage as provided for in the Trust conveyance documents.

Generally, the percentage of production proceeds to be received by the Trust with respect to a well equals the product of (i) the percentage of proceeds to which the Trust is entitled under the terms of the conveyances (90% for

Table of Contents

the Producing Wells and 50% for the PUD Wells) multiplied by (ii) ECA’s net revenue interest in the well. ECA on average owns an 81.53% net revenue interest in the Producing Wells. Therefore, the Trust is entitled to receive on average 73.37% of the proceeds of production from the Producing Wells. With respect to a PUD Well, the conveyance related to the PUD Royalty Interest provides that the proceeds from the PUD Wells will be calculated on the basis that the underlying PUD Wells are burdened only by interests that in total would not exceed 12.5% of the revenues from such properties, regardless of whether the royalty interest owners are actually entitled to a greater percentage of revenues from such properties. As the applicable net revenue interest of a well is calculated by multiplying ECA’s percentage working interest in such well by the unburdened interest percentage (87.5%), assuming ECA owns a 100% working interest in a PUD Well, such well would have a minimum 87.5% net revenue interest. Accordingly, the Trust would be entitled to 43.75% of the production proceeds from such well. To the extent ECA’s working interest in a PUD well is less than 100%, the Trust’s share of proceeds would be proportionately reduced. Pursuant to the Development Agreement, however, ECA will only satisfy its drilling obligation when it has drilled 52 equivalent wells. Therefore, any reduction in production proceeds attributable to a PUD Well caused by ECA having less than a 100% working interest in the well will be offset by the requirement to drill additional wells to achieve a total of 52 equivalent wells.

The Trust will make quarterly cash distributions of substantially all of its cash receipts, after deducting Trust administrative expenses and the costs incurred as a result of being a publicly traded entity, on or about 60 days following the completion of each quarter through (and including) the quarter ending March 31, 2030 (the “Termination Date”). The first quarterly distribution was made on August 31, 2010 to record unitholders as of August 16, 2010. The Trust will begin to liquidate on the Termination Date and will soon thereafter wind up its affairs and terminate. At the Termination Date, 50% of each of the PDP Royalty Interest and the PUD Royalty Interest will revert automatically to ECA. The remaining 50% of each of the PDP Royalty Interest and the PUD Royalty Interest will be sold, and the net proceeds will be distributed pro rata to the unitholders soon after the Termination Date. ECA will have a first right of refusal to purchase the remaining 50% of the royalty interests at the Termination Date.

In order to provide support for cash distributions on the common units, ECA has agreed to subordinate 4,401,250 of the Trust units it owns, which constitute 25% of the outstanding Trust units. The subordinated units are entitled to receive pro rata distributions from the Trust each quarter if and to the extent there is sufficient cash to provide a cash distribution on the common units which is at least equal to the applicable quarterly subordination threshold. However, if there is not sufficient cash to fund such a distribution on all Trust units, the distribution with respect to the subordinated units will be reduced or eliminated for such quarter in order to make a distribution, to the extent possible, of up to the subordination threshold amount on the common units. In exchange for agreeing to subordinate these Trust units, and in order to provide additional financial incentive to ECA to perform its drilling obligation and operations on the Underlying Properties in an efficient and cost-effective manner, ECA is entitled to receive incentive distributions equal to 50% of the amount by which the cash available for distribution on all of the Trust units in any quarter exceeds 150% of the subordination threshold for such quarter. ECA’s right to receive the incentive distributions will terminate upon the expiration of the subordination period.

ECA incurred costs of approximately $5.0 million for floor price contracts that were transferred to the Trust. ECA is entitled to reimbursement for these expenditures plus interest accrued at 10% per annum only if and to the extent distributions to Trust unitholders would otherwise exceed the incentive threshold. This reimbursement will be deducted, over time, from the 50% of cash available for distribution in excess of the incentive thresholds otherwise payable to the Trust unitholders.

The subordinated units will automatically convert into common units on a one-for-one basis and ECA’s right to receive incentive distributions and to recoup the reimbursement amount will terminate, at the end of the fourth full calendar quarter following ECA’s satisfaction of its drilling obligation to the Trust. Accordingly, ECA bears the risk that it will not be partially or fully reimbursed for the floor price contracts transferred to the Trust. ECA currently expects that it will complete its drilling obligation on or before March 31, 2013 and that, accordingly, the subordinated units will convert into common units on or before March 31, 2014. In the event of delays, it will have until March 31, 2014 under its contractual obligation to drill all the PUD Wells, in which event the subordinated units would convert into common units on or before March 31, 2015. The period during which the subordinated units are outstanding is referred to as the “subordination period.”

Table of Contents

The business and affairs of the Trust are managed by The Bank of New York Mellon Trust Company, N.A. as Trustee. Although ECA operates all of the Producing Wells and substantially all of the PUD Wells, ECA has no ability to manage or influence the management of the Trust.

NOTE 2. Basis of Presentation

The preparation of financial statements requires the Trust to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Without limiting the foregoing statement, the information furnished is based upon certain estimates of the revenues attributable to the Trust from natural gas production for the three months and six months ended June 30, 2011 and is therefore subject to adjustment in future periods to reflect actual production for the periods presented.

The information furnished reflects all adjustments which are, in the opinion of the Trustee, necessary for a fair presentation of the results for the interim period presented. The accompanying unaudited interim financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Trust’s Annual Report on Form 10-K for the year ended December 31, 2010. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America.

NOTE 3. Significant Accounting Policies

The accompanying unaudited financial information has been prepared by the Trustee in accordance with the instructions to Form 10-Q. The financial statements of the Trust differ from financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) because certain cash reserves may be established for contingencies, which would not be accrued in financial statements prepared in accordance with GAAP. Amortization of expired floor price contract premiums does not reduce Distributable Income, rather it is charged directly to Trust Corpus. Amortization of the investment in overriding royalty interests calculated on a unit-of-production basis is charged directly to Trust Corpus. This comprehensive basis of accounting other than GAAP corresponds to the accounting permitted for royalty Trusts by the U.S. Securities and Exchange Commission as specified by FASB ASC Topic 932 Extractive Activities — Oil and Gas: Financial Statements of Royalty Trusts. Income determined on the basis of GAAP would include all expenses incurred for the period presented. However, the Trust serves as a pass-through entity, with expenses for depreciation, depletion, and amortization, interest and income taxes being based on the status and elections of the Trust unitholders. General and administrative expenses, production taxes or any other allowable costs are charged to the Trust only when cash has been paid for those expenses. In addition, the royalty interest is not burdened by field and lease operating expenses. Thus, the statement purports to show distributable income, defined as income of the Trust available for distribution to the Trust unitholders before application of those additional expenses, if any, for depreciation, depletion, and amortization, interest and income taxes. The revenues are reflected net of existing royalties and overriding royalties and have been reduced by gathering/post-production expenses.

Cash:

Cash consists of highly liquid instruments with maturities at the time of acquisition of three months or less.

Use of Estimates in the Preparation of Financial Statements:

The preparation of financial statements requires the Trust to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Revenue and Expenses:

Table of Contents

Income purports to show Income available for distribution before application of those unitholders’ additional expenses, if any, for depletion, interest income and expense, and income taxes.

The Trust uses the accrual basis to recognize revenue, with royalty income recorded as reserves are extracted from the Underlying Properties and sold. Expenses are recognized when paid.

Royalty Interest in Gas Properties:

The Royalty Interests in gas properties are assessed to determine whether their net capitalized cost is impaired, whenever events or changes in circumstances indicate that its carrying amount may not be recoverable, pursuant to Accounting Standards Codification 360, Property, Plant and Equipment (“ASC 360”). The Trust will determine if a writedown is necessary to its investment in the Royalty Interests in gas properties to the extent that total capitalized costs, less accumulated amortization, exceed undiscounted future net revenues attributable to proved gas reserves of the Underlying Properties. The Trust will then provide a writedown to the extent that the net capitalized costs exceed the fair value of the investment in net profits interests attributable to proved gas reserves of the Underlying Properties. Any such writedown would not reduce Distributable Income, although it would reduce Royalty Interest in Gas Properties and Trust Corpus. No impairment in the Underlying Properties was recognized during the three month or six month periods ended June 30, 2011 or June 30, 2010. Significant dispositions or abandonment of the Underlying Properties are charged to Royalty Interests and the Trust Corpus.

Amortization of the Royalty Interests in gas properties is calculated on a units-of-production basis, whereby the Trust’s cost basis in the properties is divided by Trust total proved reserves to derive an amortization rate per reserve unit. Such amortization does not reduce Distributable Income, rather it is charged directly to Trust Corpus. Revisions to estimated future units-of-production are treated on a prospective basis beginning on the date significant revisions are known.

The conveyance of the Royalty Interests to the Trust was accounted for as a purchase transaction. The $352,100,000 reflected in the Statements of Assets, Liabilities and Trust Corpus as Royalty Interests in Gas Properties represents 17,605,000 Trust units valued at $20.00 per unit. The carrying value of the Trust’s investment in the Royalty Interests is not necessarily indicative of the fair value of such Royalty Interests.

Accrued Interest Payable:

Accrued interest payable to ECA by the Trust is calculated at 10% per annum on the outstanding balance of the floor contract premiums payable, but is not recorded by the Trust until paid. As of June 30, 2011, the amount of unrecorded accrued interest payable to ECA was $561,052.

NOTE 4. Commodity Hedges

The Trust is exposed to risk fluctuations in energy prices in the normal course of operations. ECA conveyed to the Trust natural gas derivative floor price contracts and entered into a back-to-back swap agreement with the Trust which conveyed the benefit of certain swap agreements which ECA had previously entered into with third parties. The volumes covered by these agreements equate to approximately 50% of the estimated natural gas to be produced by the Trust properties through March 31, 2014. The swap contracts relate to approximately 7,500 MMBtu per day at a weighted average price of $6.78 per MMBtu for the period from April 1, 2010 through June 30, 2012. The price of the floor hedging contracts is $5.00 per MMBtu on a total volume of 11,268,000 MMBtu for the period from October 1, 2010 through March 31, 2014. The Trust uses the cash method to account for commodity contracts. Under this method, gains or losses associated with the contracts are recognized at the time the hedged production occurs.

Hedge proceeds realized for the quarter ended June 30, 2011 and 2010 totaled $1,805,863 and $1,814,543. Hedge proceeds for the six months ended June 30, 2011 and from inception to date period ended June 30, 2010 totaled $3,735,436 and $1,814,543. The fair market values of the commodity contracts are not included in the accompanying financial statements, as the statements are presented on a modified cash basis of accounting.

NOTE 5. Income Taxes

The Trust is a Delaware statutory trust, which is taxed as a partnership for federal and state income taxes. Accordingly, no provision for federal or state income taxes has been made.

NOTE 6. Related Party Transactions

Trustee Administrative Fee:

Under the terms of the Trust agreement, the Trust pays an annual administrative fee of $150,000 to the Trustee, which may be adjusted beginning on the fifth anniversary of the Trust as provided in the Trust agreement. These costs, as well as those to be paid to ECA pursuant to the Administrative Services Agreement referred to below, will be deducted by the Trust in the period paid. The Trustee waived its administrative fee for the quarter ended June 30, 2010, but does not intend to waive the fee for any other quarter.

Administrative Services Fee:

The Trust entered into an Administrative Services Agreement with ECA that obligates the Trust to pay ECA each quarter an administrative services fee for accounting, bookkeeping and informational services to be performed by ECA on behalf of the Trust relating to the Royalties. The annual fee of $60,000 is payable in equal quarterly installments. After the completion of ECA’s drilling obligation, under certain circumstances, ECA and the Trustee each may terminate the Administrative Services Agreement at any time following delivery of notice no less than 90 days prior to the date of termination. ECA waived its administrative services fee for the quarter ended June 30, 2010, but does not intend to waive the fee for any other quarter.

Drilling Support Lien:

As described in Note 1, ECA has granted to the Trust the Drilling Support Lien. The Drilling Support Lien is limited to $91 million, and as ECA fulfills its drilling obligation over time, the total dollar amount is to be proportionately reduced. As of June 30, 2011, ECA had received partial releases of the Drilling Support Lien in the amount of approximately $38.3 million reducing the Drilling Support Lien to approximately $52.7 million. However, after giving effect to the total number of wells drilled as of June 30, 2011 (37.14 wells, calculated as provided in the Development Agreement) the maximum amount of the Drilling Support Lien would be reduced to approximately $26.0 million.

Secondary Offering:

On April 12, 2011 the Trust entered into an underwriting agreement (the “Underwriting Agreement”) with ECA and the underwriters named therein (the “Underwriters”) providing for the offer and sale in a firm commitment underwritten offering by ECA of 2,525,000 units of beneficial interest in the Trust (“Common Units”) at a public offering price of $29.35 per Common Unit. Pursuant to the Underwriting Agreement, ECA granted the Underwriters a 30-day option to purchase up to 360,723 Common Units to cover over-allotments, if any. Pursuant to this agreement ECA sold 2,525,000 Common Units in a secondary public offering and an additional 181,175 Common Units pursuant to the overallotment option during the quarter ended June 30, 2011. ECA also conveyed an additional 114,600 Common Units to certain employees of ECA in May 2011. As of June 30, 2011, ECA held a total of 180,958 Common Units and 4,401,250 subordinated units of the Trust.

NOTE 7. Subsequent Events

As of August 10, 2011, ECA had received partial releases of the Drilling Support Lien in the amount of approximately $46.9 million reducing the Drilling Support Lien to approximately $44.1 million.

As of August 10, 2011, four additional PUD Wells (4.94 Equivalent PUD Wells) had been brought online by ECA that were producing 3,303 Mcf per day net to the Trust’s interest.

Overview

The Trust is a statutory trust created under the Delaware Statutory Trust Act. The Bank of New York Mellon Trust Company, N.A. serves as trustee. The Trust does not conduct any operations or activities. The Trust’s purpose is, in general, to hold the Royalties (described below), to distribute to the Trust unitholders cash that the Trust receives in respect of the Royalties after the payment of Trust expenses. The Trustee performs certain administrative functions in respect of the Royalties and the Trust units. The Trust derives all or substantially all of its income and cash flows from the Royalties, which in turn are subject to the Hedge Contracts described in Part I, Item 3. The Trust is treated as a partnership for federal income tax purposes.

Initially, the Trust owned royalty interests in the 14 Producing Wells described in the Prospectus (the “Producing Wells”) and royalty interests in 52 horizontal natural gas development wells to be drilled to the Marcellus Shale formation (the “PUD Wells”) within the “Area of Mutual Interest,” or “AMI”, in which ECA presently holds approximately 9,300 acres, of which it owns substantially all of the working interests, in Greene County, Pennsylvania. The Area of Mutual Interest consists of the Marcellus Shale formation in approximately 121 square miles in Greene County, Pennsylvania.

The royalty interests were conveyed from ECA’s working interest in the Producing Wells and the PUD Wells limited to the Marcellus Shale formation (the “Underlying Properties”). The royalty interest in the Producing Wells (the “PDP Royalty Interest”) entitles the Trust to receive 90% of the proceeds (exclusive of any production or development costs but after deducting post-production costs and any applicable taxes) from the sale of production of natural gas attributable to ECA’s interest in the Producing Wells for a period of 20 years commencing on April 1, 2010 and 45% thereafter. The royalty interest in the PUD Wells (the “PUD Royalty Interest”) entitles the Trust to receive 50% of the proceeds (exclusive of any production or development costs but after deducting post-production costs and any applicable taxes) from the sale of production of natural gas attributable to ECA’s interest in the PUD Wells for a period of 20 years commencing on April 1, 2010 and 25% thereafter. Approximately 50% of the estimated natural gas production attributable to the Trust’s royalty interests has been hedged with a combination of floors and swaps through March 31, 2014. ECA is entitled to recoup its costs of establishing the floor price contracts only if and to the extent cash available for distribution by the Trust exceeds certain levels.

ECA is obligated to drill all of the PUD Wells by March 31, 2013. However, in the event of delays, ECA will have until March 31, 2014 to fulfill its drilling obligation. As of June 30, 2011, ECA had drilled 37.14 of the PUD Wells, calculated as provided in the Development Agreement. The Trust is not responsible for any costs related to the drilling of development wells or any other development or operating costs. The Trust’s cash receipts in respect of the royalties are determined after deducting post-production costs and any applicable taxes associated with the PDP and PUD Royalty Interests. The Trust’s cash available for distribution includes cash receipts from the Hedge Contracts and is reduced by Trust administrative expenses and expenses incurred as a result of being a publicly traded entity. Post-production costs generally consist of costs incurred to gather, compress, transport, process, treat, dehydrate and market the natural gas produced. Any charge payable to ECA for such post-production costs on its Greene County Gathering System is limited to $0.52 per MMBtu gathered until ECA has fulfilled its drilling obligation (the “Post-Production Services Fee”); thereafter, ECA may increase the Post-Production Services Fee to the extent necessary to recover certain capital expenditures in the Greene County Gathering System.

Generally, the percentage of production proceeds to be received by the Trust with respect to a well will equal the product of (i) the percentage of proceeds to which the Trust is entitled under the terms of the conveyances (90% for the Producing Wells and 50% for the PUD Wells) multiplied by (ii) ECA’s net revenue interest in the well. ECA on average owns an 81.53% net revenue interest in the Producing Wells. Therefore, the Trust will be entitled to receive on average 73.37% of the proceeds of production from the Producing Wells. With respect to a PUD Well, the conveyance related to the PUD Royalty Interest provides that the proceeds from the PUD Wells will be calculated on the basis that the underlying PUD Wells are burdened only by interests that in total would not exceed 12.5% of the revenues from such properties, regardless of whether the royalty interest owners are actually entitled to a greater percentage of revenues from such properties. As the applicable net revenue interest of a well is calculated by multiplying ECA’s percentage working interest in such well by the unburdened interest percentage (87.5%), assuming ECA owns a 100% working interest in a PUD Well, such well would have a minimum 87.5% net revenue interest. Accordingly, the Trust would be entitled to 43.75% of the production proceeds from such well. To the extent ECA’s working interest in a PUD Well is less than 100%, the Trust’s share of proceeds would be

Table of Contents

proportionately reduced. Pursuant to the Development Agreement, however, ECA will only satisfy its drilling obligation when it has drilled 52 equivalent wells. Therefore, any reduction in production proceeds attributable to a PUD Well caused by ECA having less than a 100% working interest in the well will be offset by the requirement to drill additional wells to achieve a total of 52 equivalent wells.

The Trust expects to make quarterly cash distributions of substantially all of its cash receipts, after deducting Trust administrative expenses and the costs incurred as a result of being a publicly traded entity and reserves on or about 60 days following the completion of each quarter through (and including) the quarter ending March 31, 2030 (the “Termination Date”). The first quarterly distribution was made on August 31, 2010 to record unitholders as of August 16, 2010.

The amount of Trust revenues and cash distributions to Trust unitholders will depend on:

· the timing of initial production from the PUD Wells;

· natural gas prices received;

· the volume and Btu rating of natural gas produced and sold;

· post-production costs and any applicable taxes;

· the reimbursement by the Trust, if any, of ECA’s costs associated with establishing the floor price contracts transferred to the Trust; and

· administrative expenses of the Trust and expenses incurred as a result of being a publicly traded entity, and any changes in amounts reserved for such expenses.

The amount of the quarterly distributions will fluctuate from quarter to quarter, depending on the proceeds received by the Trust, among other factors. There is no minimum required distribution. However, in order to provide support for cash distributions on the common units, ECA has agreed to subordinate 4,401,250 of the Trust units it owns, which constitute 25% of the outstanding Trust units. While the subordinated units will be entitled to receive pro rata distributions from the Trust if and to the extent there is sufficient cash to provide a cash distribution on the common units which is no less than the applicable quarterly subordination thresholds set forth below, if there is not sufficient cash to fund such a distribution on all Trust units, the distribution to be made with respect to the subordinated units will be reduced or eliminated in order to make a distribution, to the extent possible, of up to the subordination threshold amount on the common units. In exchange for agreeing to subordinate these Trust units, and in order to provide additional financial incentive to ECA to perform its drilling obligation and operations on the Underlying Properties in an efficient and cost-effective manner, ECA is entitled to receive incentive distributions equal to 50% of the amount by which the cash available for distribution on all of the Trust units in any quarter exceeds 150% of the subordination threshold for such quarter. ECA’s right to receive the incentive distributions will terminate upon the expiration of the subordination period.

ECA incurred costs of approximately $5.0 million for floor price contracts transferred to the Trust. ECA is entitled to reimbursement for these expenditures plus interest accrued at 10% per annum (“Reimbursement Amount”) only if and to the extent distributions to Trust unitholders would otherwise exceed the incentive threshold. This reimbursement will be deducted, over time, from the 50% of cash available for distribution in excess of the incentive thresholds otherwise payable to the Trust unitholders.

The subordinated units will automatically convert into common units on a one-for-one basis and ECA’s right to receive incentive distributions and to recoup the Reimbursement Amount will terminate, at the end of the fourth full calendar quarter following ECA’s satisfaction of its drilling obligation to the Trust. The Trust currently expects that ECA will complete its drilling obligation on or before March 31, 2013 and that, accordingly, the subordinated units would convert into common units on or before March 31, 2014. In the event of delays, ECA will have until March 31, 2014 under the Development Agreement to drill all the PUD Wells, in which event the subordinated units would convert into common units on or before March 31, 2015.

Table of Contents

The table below sets forth the subordination and incentive thresholds for each calendar quarter through the first quarter of 2015. The effective date of the Trust is April 1, 2010, meaning it has received the proceeds of production attributable to the PDP Royalty Interest from that date even though the PDP Royalty Interest was not conveyed to the Trust until July 7, 2010.

Results of Trust Operations

For the Three Months Ended June 30, 2011 and Three Months Ended June 30, 2010

Distributable income for the three months ended June 30, 2011 increased to $11.1 million from $4.8 million for the three months ended June 30, 2010. This increase was primarily the result of a $6.2 million increase in royalty income and a $0.7 million reduction in cash reserves established by the Trustee, which were partially offset by a $0.6 million increase in general and administrative expenses.

Royalty income increased by $6.2 million, from $3.7 million for the three months ended June 30, 2010 to $9.9 million for the three months ended June 30, 2011 as a result of an increase in production, partially offset by a decrease in the average realized price and an increase in post production costs.

Table of Contents

Production increased 160% from 968 MMcf for the three months ended June 30, 2010 to 2,512 MMcf for the three months ended June 30, 2011. The increased production was a result of an increase in the number of wells online and producing during the quarter ended June 30, 2011. A total of thirty-one wells (14 PDP and 17 actual PUD wells (21.89 Equivalent PUD Wells as calculated as described in the Prospectus)) were online and producing as of June 30, 2011, while there were a total of 8 PDP Wells online and producing as of June 30, 2010. Of the seventeen PUD Wells, seven (9.43 Equivalent PUD Wells) of these wells were brought online during the quarter ended June 30, 2011. Three wells (3.83 Equivalent PUD Wells) were brought online in early April, three (4.20 Equivalent PUD Wells) in late April and one well (1.40 Equivalent PUD Wells) was brought online in mid May. Subsequently, these seven wells (9.43 Equivalent PUD Wells) had an average daily production rate, net to the Trust, of 9,482 Mcf per day for June 2011. The average gross initial per well production for the first thirty days of production for these seven wells (9.43 Equivalent PUD Wells) was 3,345 Mcf per day.

The average price realized for the three months ended June 30, 2011 declined by $1.09 per Mcf to $4.66 per Mcf as compared to $5.75 per Mcf for the three months ended June 30, 2010. This decrease was primarily the result of a decrease in the percentage of volumes hedged from 70.5% for the three months ended June 30, 2010 to 35.5% for the three months ended June 30, 2011. The Trust had swaps covering a total of 682,500 MMbtu, at a price of $6.75 per MMbtu, for the quarters ended June 30, 2010 and 2011 and had floors at a price of $5.00 per MMbtu covering a total of 200,000 MMbtu for the quarter ended June 30, 2011. This decrease was partially offset by an increase in the weighted average monthly closing NYMEX price for the current quarter to $4.32 per MMbtu from the comparable quarter in 2010.

Post production costs averaged $0.62 per Dth for the quarter ended June 30, 2011 as compared to $0.52 per Dth for the prior year’s comparable quarter. Post production costs were higher than the previous year’s quarter due to the utilization of electric compression versus gas compression which resulted in a charge for electric usage, in lieu of gas used as fuel, which is a chargeable cost and properly allocated to the Trust, as provided for in the Trust conveyance documents.

General and administrative expenses paid by the Trust were $0.6 million for the three months ended June 30, 2011. No such expenses were paid during the quarter ended June 30, 2010 as a result of the closing of the initial public offering not occurring until July 7, 2010. For the quarter ended June 30, 2010, the Trustee established a cash reserve of $0.7 million for use in paying the current and future liabilities of the Trust as they became due. This cash reserve reduced the Trust’s distributable income for the period. The cash reserve was not increased or decreased during the quarter ended June 30, 2011.

ECA has drilled an additional fifteen PUD Wells (19.27 Equivalent PUD Wells) as of August 10, 2011. Of these fifteen (19.27 Equivalent PUD Wells) additional wells, four wells (4.94 Equivalent PUD Wells) were turned online and producing while eleven wells (14.33 Equivalent PUD Wells) were undergoing or awaiting Completion operations. To date, ECA has drilled a total of thirty-two actual PUD Wells (41.16 Equivalent PUD Wells calculated as described in the Prospectus). These 41.16 Equivalent PUD Wells drilled count toward the 52 equivalent PUD Wells ECA has committed to drill.

For the Six Months Ended June 30, 2011 and Inception to Date Period Ended June 30, 2010

Distributable income for the six months ended June 30, 2011 increased to $20.3 million from $4.8 million for the inception to date period ended June 30, 2010. This increase was primarily the result of a $14.1 million increase in royalty income, a $1.9 million increase in hedge proceeds and a $0.7 million reduction in cash reserves established by the Trustee, which were partially offset by a $1.2 million increase in general and administrative expenses.

Royalty income increased by $14.1 million, from $3.7 million for the inception to date period ended June 30, 2010 to $17.8 million for the six months ended June 30, 2011 as a result of an increase in production, partially offset by a decrease in the average realized price and an increase in post production costs.

Production increased 376% from 968 MMcf for the inception to date ended June 30, 2010 to 4,609 MMcf for the six months ended June 30, 2011. The increased production was a result of an increase in the number of wells in

Table of Contents

line and producing during the period ended June 30, 2011. A total of thirty-one wells (14 PDP and 17 actual PUD wells (21.89 Equivalent PUD Wells as calculated as described in the Prospectus)) were online and producing as of June 30, 2011, while there were a total of 8 PDP Wells online and producing as of June 30, 2010. Of the seventeen PUD Wells (21.89 Equivalent PUD Wells), eleven of these wells (15.03 Equivalent PUD Wells) were brought online during the period ended June 30, 2011. Two wells (2.80 Equivalent PUD Wells) were brought online in January, two in March (2.80 Equivalent PUD Wells), six (8.03 Equivalent PUD Wells) in April and one well (1.40 Equivalent PUD Wells) was brought online in mid May. Subsequently, these eleven wells (15.03 Equivalent PUD Wells) had an average daily production rate, net to the Trust, of 13,854 Mcf per day for June 2011. The average gross initial per well production for the first thirty days of production for these eleven wells (15.03 Equivalent PUD Wells) was 3,343 Mcf per day.

The average price realized for the six months ended June 30, 2011 declined by $1.07 per Mcf to $4.68 per Mcf as compared to $5.75 per Mcf for the inception to date period ended June 30, 2010. This decrease was primarily the result of a decrease in the percentage of volumes hedged from 70.5% for the inception to date period ended June 30, 2010 to 37.5% for the six months ended June 30, 2011. The Trust had swaps covering a total of 682,500 MMbtu, at a price of $6.75 per MMbtu, for the inception to date ended June 30, 2010 and 1,357,500 MMbtu at a price of $6.75 for the inception to date period ended June 30, 2011. The Trust also had in place floor contracts at a price of $5.00 per MMbtu covering a total of 369,000 MMbtu for the six months ended June 30, 2011. This decrease was partially offset by an increase in the weighted average monthly closing NYMEX price for the current period to $4.22 per MMbtu from the comparable period in 2010.

Post production costs averaged $0.63 per Dth for the six months ended June 30, 2011 as compared to $0.52 per Dth for the prior year’s comparable period. Post production costs were higher than the previous year due to the utilization of electric compression versus gas compression which resulted in a charge for electric usage, in lieu of gas used as fuel, which is a chargeable cost and properly allocated to the Trust, as provided for in the Trust conveyance documents.

General and administrative expenses paid by the Trust were $1.2 million for the six months ended June 30, 2011. No such expenses were paid during the period ended June 30, 2010 as a result of the closing of the initial public offering not occurring until July 7, 2010. For the period ended June 30, 2010, the Trustee established a cash reserve of $0.7 million for use in paying the current and future liabilities of the Trust as they became due. This cash reserve reduced the Trust’s distributable income for the period. The cash reserve was not increased or decreased during the six months ended June 30, 2011.

Liquidity and Capital Resources

The Trust has no source of liquidity or capital resources other than cash flows from the Royalties and the Hedge Arrangements. Other than Trust administrative expenses, including any reserves established by the Trustee for future liabilities, the Trust’s only use of cash is for distributions to Trust unitholders, including, if applicable, incentive distributions to ECA and, if applicable, expense reimbursements to ECA. Administrative expenses include payments to the Trustee and the Delaware Trustee as well as a quarterly fee of $15,000 to ECA pursuant to the Administrative Services Agreement. Each quarter, the Trustee determines the amount of funds available for distribution. Available funds are the excess cash, if any, received by the Trust from the Royalties and other sources (such as interest earned on any amounts reserved by the Trustee) that quarter, over the Trust’s expenses for that quarter, subject in all cases to the subordination and incentive provisions described above. Available funds are reduced by any cash the Trustee determines to hold as a reserve against future expenses or liabilities. The Trustee may borrow funds required to pay expenses or liabilities if the Trustee determines that the cash on hand and the cash

Table of Contents

to be received are insufficient to cover the Trust’s expenses or liabilities. If the Trustee borrows funds, the Trust unitholders will not receive distributions until the borrowed funds are repaid.

Payments to the Trust in respect of the Royalties are based on the complex provisions of the various Conveyances held by the Trust, copies of which are filed as exhibits to this report, and reference is hereby made to the text of the Conveyances for the actual calculations of amounts due to the Trust.

The Trust does not have any transactions, arrangements or other relationships with unconsolidated entities or persons that could materially affect the Trust’s liquidity or the availability of capital resources.

Critical Accounting Policies and Estimates

Significant Accounting Policies

The financial statements of the Trust differ from financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) because certain cash reserves may be established for contingencies, which would not be accrued in financial statements prepared in accordance with GAAP. Amortization of the investment in overriding royalty interests calculated on a unit-of-production basis is charged directly to Trust Corpus. This comprehensive basis of accounting other than GAAP corresponds to the accounting permitted for royalty Trusts by the U.S. Securities and Exchange Commission as specified by FASB ASC Topic 932 Extractive Activities — Oil and Gas: Financial Statements of Royalty Trusts.

Income determined on the basis of GAAP would include all expenses incurred for the period presented. However, the Trust serves as a pass-through entity, with expenses for depreciation, depletion, and amortization, interest and income taxes being based on the status and elections of the Trust unitholders. General and administrative expenses, production taxes or any other allowable costs will only be charged to the Trust when cash has been paid for those expenses. In addition, the royalty interest is not burdened by field and lease operating expenses. Thus, the statement purports to show distributable income, defined as income of the Trust available for distribution to the Trust unitholders before application of those additional unitholders’ additional expenses, if any, for depreciation, depletion, and amortization, interest and income taxes. The revenues are reflected net of existing royalties and overriding royalties and have been reduced by gathering/post-production expenses.

Revenue and Expenses:

The Trust serves as a pass-through entity, with items of depletion, interest income and expense, and income tax attributes being based upon the status and election of the unitholders. Thus, the Statements of Distributable Income purport to show Income available for distribution before application of those unitholders’ additional expenses, if any, for depletion, interest income and expense, and income taxes.

The Trust uses the accrual basis to recognize revenue, with royalty income recorded as reserves are extracted from the Underlying Properties and sold. Expenses are recognized when paid.

Royalty Interest in Gas Properties:

The Royalty Interests in gas properties are assessed to determine whether their net capitalized cost is impaired, whenever events or changes in circumstances indicate that its carrying amount may not be recoverable, pursuant to Accounting Standards Codification 360, Property, Plant and Equipment (“ASC 360”). The Trust will determine if a write down is necessary to its investment in the Royalty Interests in gas properties to the extent that total capitalized costs, less accumulated amortization, exceed undiscounted future net revenues attributable to proved gas reserves of the Underlying Properties. The Trust will then provide a write down to the extent that the net capitalized costs exceed the fair value of the investment in net profits interests attributable to proved gas reserves of the Underlying Properties. Any such write down would not reduce Distributable Income, although it would reduce Trust Corpus.

Significant dispositions or abandonment of the Underlying Properties are charged to Royalty Interests and the Trust Corpus.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

Hedge Contracts

The primary asset of and source of income to the Trust is the Royalties, which generally entitle the Trust to receive varying portions of the net proceeds from gas production from the Underlying Properties. Consequently, the Trust is exposed to market risk from fluctuations in gas prices. Through March 31, 2014, however, the Royalties are subject to the hedge contracts described below, which are expected to reduce the Trust’s exposure to natural gas price volatility.

The hedge contracts consist of natural gas derivative floor price contracts and a back-to-back swap agreement ECA entered into with the Trust to provide the Trust with the benefit of certain contracts previously entered into between ECA and third parties that equate to approximately 50% of the estimated natural gas to be produced by the Trust properties from April 1, 2010 through March 31, 2014. The swap contracts relate to approximately 7,500 MMBtu per day at a weighted average price of $6.78 per MMBtu for the period commencing as of April 1, 2010 through June 30, 2012. The price of any floor price hedging contract is $5.00 per MMBtu.

The following table sets forth the volumes of natural gas covered by the natural gas hedging contracts and the floor price for each quarter during the term of the contracts.

	Swap Volume	Swap Price		Floor Volume	Floor Price
	(MMBtu)	(MMBtu)		(MMBtu)	(MMBtu)

The Trust’s counterparties under the natural gas floor price contracts are Wells Fargo Foothill, Inc. and BP Energy Company, and its counterparty under the back-to-back swap agreement is ECA, whose counterparties are also Wells Fargo Foothill, Inc. and BP Energy Company. In the event that any of the counterparties to the natural gas hedging contracts default on their obligations to make payments to the Trust, the cash distributions to the Trust unitholders would likely be materially reduced as the hedge payments are intended to provide additional cash to the Trust during periods of lower natural gas prices. ECA has no continuing obligation with respect to the natural gas

Table of Contents

floor price contracts. However, ECA will be the Trust’s counterparty under the back-to-back swap agreement and will have continuing obligations with respect to this agreement.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures. The Trustee maintains disclosure controls and procedures designed to ensure that information required to be disclosed by the Trust in the reports that it files or submits under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Trust in the reports that it files or submits under the Act is accumulated and communicated by ECA to The Bank of New York Mellon Trust Company, N.A., as Trustee of the Trust, and its employees who participate in the preparation of the Trust’s periodic reports as appropriate to allow timely decisions regarding required disclosure.

As of the end of the period covered by this report, the Trustee carried out an evaluation of the Trustee’s disclosure controls and procedures. Mike Ulrich, as Trust Officer of the Trustee, has concluded that the disclosure controls and procedures of the Trust are effective.

Due to the contractual arrangements of the Trust Agreement and the conveyances, the Trustee relies on (i) information provided by ECA, including historical operating data, plans for future operating and capital expenditures, reserve information and information relating to projected production, and (ii) conclusions and reports regarding reserves by the Trust’s independent reserve engineers. See Item 1A “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operation”, for a description of certain risks relating to these arrangements and reliance on information.

Changes in Internal Control over Financial Reporting. During the quarter ended June 30, 2011, there has been no change in the Trustee’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Trustee’s internal control over financial reporting relating to the Trust. The Trustee notes for purposes of clarification that it has no authority over, and makes no statement concerning, the internal control over financial reporting of ECA.
