REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors of Encore Energy Partners GP LLC:

     We have audited the accompanying consolidated balance sheet of Encore Energy Partners GP LLC (the “Company”) as of December 31, 2007. This balance sheet is the responsibility of the Company’s management. Our responsibility is to express an opinion on this balance sheet 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 balance sheet is free of material misstatement. We were not engaged to perform an audit of the Company’s 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 Company’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 balance sheet, assessing the accounting principles used and significant estimates made by management, and evaluating the overall balance sheet presentation. We believe that our audit of the balance sheet provides a reasonable basis for our opinion.

     In our opinion, the consolidated balance sheet referred to above presents fairly, in all material respects, the consolidated financial position of Encore Energy Partners GP LLC at December 31, 2007, in conformity with U.S. generally accepted accounting principles.

     As discussed in Note 2 to the consolidated balance sheet, on January 1, 2007, the Company adopted Financial Accounting Standards Board Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an Interpretation of FASB Statement No. 109.”

NOTES TO CONSOLIDATED BALANCE SHEET

Note 1. Formation of the Company and Description of Business

     Encore Energy Partners GP LLC (the “General Partner”), a Delaware limited liability company, was formed in February 2007 to serve as the general partner of Encore Energy Partners LP (“ENP” or the “Partnership”), a Delaware limited partnership. The General Partner is a wholly owned subsidiary of Encore Partners GP Holdings LLC, a Delaware limited liability company and direct wholly owned subsidiary of Encore Acquisition Company (“EAC”), a publicly traded Delaware corporation. As of December 31, 2007, the General Partner owned a 2 percent general partner interest in the Partnership. The General Partner does not own an interest in any other entities. As of December 31, 2007, approximately 58 percent of the Partnership’s outstanding common units were owned by EAC and its subsidiaries.

     The Partnership was formed in February 2007 by EAC to acquire, exploit, and develop oil and natural gas properties and to acquire, own, and operate related assets. Also in February 2007, Encore Energy Partners Operating LLC (“OLLC”), a Delaware limited liability company and wholly owned subsidiary of the Partnership, was formed to own and operate ENP’s properties. The Partnership’s properties — and oil and natural gas reserves — are located in three core areas:

• the Big Horn Basin of Wyoming and Montana, primarily in the Elk Basin field (the “Elk Basin Assets”);

• the Permian Basin of West Texas; and

• the Williston Basin of North Dakota.

Initial Public Offering and Concurrent Transactions

     In September 2007, the Partnership completed its initial public offering (“IPO”) of 9,000,000 common units at a price to the public of $21.00 per unit. The net proceeds of $171.0 million, after deducting the underwriters’ discount and a structuring fee of $13.2 million, in the aggregate, and offering expenses of $4.7 million, were used to repay in full $126.4 million, including accrued interest, of outstanding indebtedness under OLLC’s subordinated credit agreement and $43.5 million of outstanding borrowings under OLLC’s revolving credit facility. See “Note 6. Debt” for additional discussion of the Partnership’s long-term debt.

     In October 2007, the underwriters exercised their over-allotment option to purchase an additional 1,148,400 common units. The net proceeds of $22.4 million, after deducting the underwriters’ discount and a structuring fee of $1.7 million, in the aggregate, were used to repay outstanding borrowings under OLLC’s revolving credit facility. After completion of the IPO and the underwriters’ over-allotment exercise, approximately 42 percent of the Partnership’s common units were publicly held.

     At the closing of the IPO, the following transactions were completed:

(a) The Partnership entered into a contribution, conveyance and assumption agreement (the “Contribution Agreement”) with the General Partner, OLLC, EAC, Encore Operating, L.P. (“Encore Operating”), a Texas limited partnership and indirect wholly owned subsidiary of EAC, and Encore Partners LP Holdings LLC, a Delaware limited liability company and direct wholly owned subsidiary of EAC. The following transactions, among others, occurred pursuant to the Contribution Agreement:

• Encore Operating transferred certain oil and natural gas properties and related assets in the Permian Basin of West Texas (the “Permian Basin Assets”) to the Partnership in exchange for 4,043,478 common units; and

• EAC agreed to indemnify the Partnership for certain environmental liabilities, tax liabilities, and title defects, as well as defects relating to retained assets and liabilities, occurring or existing before the closing.

These transfers and distributions were made in a series of steps outlined in the Contribution Agreement. In connection with the issuance of the common units by the Partnership in exchange for the Permian Basin Assets, the IPO, and the exercise of the underwriters’ option to purchase additional common units, the General Partner exchanged a certain number of common units for general partner units to enable it to maintain its 2 percent general partner interest.

(b)

The Partnership entered into an amended and restated administrative services agreement (the “Administrative Services Agreement”) with the General Partner, OLLC, Encore Operating, and EAC. Encore Operating performs administrative services for the Partnership, such as accounting, corporate development, finance, land, legal, and engineering. In addition, Encore Operating provides all personnel and any facilities, goods, and equipment necessary to perform these

	services and not otherwise provided by the Partnership. Encore Operating initially received an administrative fee of $1.75 per BOE of the Partnership’s production for such services and reimbursement of actual third-party expenses incurred on the Partnership’s behalf. In addition, Encore Operating is entitled to retain any COPAS overhead charges associated with drilling and operating wells that would otherwise be paid by non-operating interest owners to the operator of a well.
	The Partnership reimburses EAC for any additional state income, franchise, or similar tax paid by EAC resulting from the inclusion of the Partnership (and its subsidiaries) in a combined state income, franchise, or similar tax report with EAC as required by applicable law. The amount of any such reimbursement is limited to the tax that the Partnership (and its subsidiaries) would have paid had it not been included in a combined group with EAC. See “Note 10. Related Party Transactions” for additional discussion regarding the Administrative Services Agreement.
(c)	The Encore Energy Partners GP LLC Long-Term Incentive Plan (the “ENP Incentive Plan”) was approved, which applies to employees, consultants, and directors of EAC, the General Partner, and any of their affiliates who perform services for the Partnership. See “Note 8. Unit-Based Compensation Plans” for additional discussion regarding the ENP Incentive Plan.

Note 2. Summary of Significant Accounting Policies

Basis of Presentation

     In accordance with Emerging Issues Task Force (“EITF”) Issue No. 04-5,“Determining Whether a General Partner, or the General Partners as a Group, Controls a Limited Partnership or Similar Entity When the Limited Partners Have Certain Rights,”the General Partner is deemed to control the Partnership. Under Delaware law and the partnership agreement, the General Partner has the power to direct or cause the direction of the management and the policies of the Partnership. As a result of this substantive control, the Partnership is fully consolidated by the General Partner. The accompanying Consolidated Balance Sheet includes the accounts of the General Partner and the Partnership, its controlled subsidiary (collectively, the “Company”). The public unitholders’ interest is reflected as “Minority interest” in the accompanying Consolidated Balance Sheet. The Company elected to account for gains on ENP’s issuance of common units as capital transactions as permitted by Staff Accounting Bulletin Topic 5H, “Accounting for Sales of Stock by a Subsidiary.” During 2007, the Company reclassified $77.6 million from “Minority interest” to “Owner’s net equity” on the accompanying Consolidated Balance Sheet to recognize the gain on sale of ENP’s common units. All material intercompany balances and transactions have been eliminated in consolidation.

     As discussed above, upon completion of the Partnership’s IPO, EAC contributed the Permian Basin Assets to the Partnership. The contribution of the Permian Basin Assets by EAC was accounted for as a transaction between entities under common control, similar to a pooling of interests. Therefore, the assets and liabilities of the Permian Basin Assets were recorded on the Company’s balance sheet at EAC’s historical basis. In February 2008, the Partnership completed the acquisition of additional oil and natural gas properties and related assets in the Permian Basin of West Texas and oil and natural gas properties and related assets in the Williston Basin of North Dakota (the “Permian and Williston Basin Assets”) from Encore Operating. Because the Permian and Williston Basin Assets were acquired from an affiliate, this acquisition was also accounted for as a transaction between entities under common control, whereby the assets and liabilities were recorded at Encore Operating’s historical cost and the Company’s historical balance sheet was recast to include the acquired properties. Accordingly, the accompanying Consolidated Balance Sheet and notes thereto reflect the combined financial position of the Company, the Permian Basin Assets, and the Permian and Williston Basin Assets as of December 31, 2007.

Use of Estimates

     Preparing financial statements in conformity with accounting principles generally accepted in the United States requires management to make certain estimations and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities in the consolidated balance sheet. Actual results could differ materially from those estimates.

     Estimates made in preparing this consolidated balance sheet include, among other things, estimates of the proved oil and natural gas reserve volumes used in calculating depletion, depreciation, and amortization (“DD&A”) expense; the estimated future cash flows and fair value of properties used in determining the need for any impairment write-down; operating costs

NOTES TO CONSOLIDATED BALANCE SHEET — Continued

accrued; volumes and prices for revenues accrued; and the timing and amount of future abandonment costs used in calculating asset retirement obligations. Future changes in the assumptions used could have a significant impact on reported results in future periods.

Cash and Cash Equivalents

     Cash and cash equivalents include cash in banks, money market accounts, and all highly liquid investments with an original maturity of three months or less.

Accounts Receivable

     The Company’s trade accounts receivable, which are primarily from oil and natural gas sales, are recorded at the invoiced amount and do not bear interest. The Company routinely reviews outstanding accounts receivable balances and assesses the financial strength of its customers. A reserve is recorded for amounts it expects will not be fully recovered. Actual balances are not applied against the reserve until substantially all collection efforts have been exhausted. At December 31, 2007, the Company did not have any allowance for doubtful accounts.

Properties and Equipment

     Oil and Natural Gas Properties.The Company adheres to Statement of Financial Accounting Standards (“SFAS”) No. 19, “Financial Accounting and Reporting by Oil and Gas Producing Companies", utilizing the successful efforts method of accounting for its oil and natural gas properties. Under this method, all costs associated with productive and nonproductive development wells are capitalized. Costs associated with drilling exploratory wells are initially capitalized pending determination of whether the well is economically productive or nonproductive.

     If an exploratory well does not find reserves or does not find reserves in a sufficient quantity as to make them economically producible, the previously capitalized costs are expensed in the period in which the determination was made. If an exploratory well finds reserves but they cannot be classified as proved, the Company continues to capitalize the associated cost as long as the well has found a sufficient quantity of reserves to justify its completion as a producing well and sufficient progress is being made in assessing the reserves and the operating viability of the project. If subsequently it is determined that neither of these conditions continues to exist, all previously capitalized costs associated with the exploratory well are expensed. Re-drilling or directional drilling in a previously abandoned well is classified as development or exploratory based on whether it is in a proved or unproved reservoir. Expenditures to recomplete a current well in a different unproved reservoir are capitalized pending determination that economic reserves have been added. If the recompletion is not successful, the expenditures are charged to expense.

     Significant tangible equipment added or replaced is capitalized. Expenditures to construct facilities or increase the productive capacity from existing reservoirs are capitalized. Capitalized costs are amortized on a unit-of-production basis over the remaining life of proved developed reserves or total proved reserves, as applicable. Natural gas volumes are converted to barrels of oil equivalent (“BOE”) at the rate of six thousand cubic feet (“Mcf”) of natural gas to one barrel (“Bbl”) of oil.

     The costs of retired, sold, or abandoned properties that constitute part of an amortization base are charged or credited, net of proceeds received, to the accumulated DD&A reserve. Gains or losses from the disposal of other properties are recognized in the current period.

     Reserve engineers estimate the Partnership’s reserves annually on December 31. This results in a new DD&A rate which the Company uses for the preceding fourth quarter after adjusting for fourth quarter production. The Company internally estimates reserve additions and reclassifications of reserves from proved undeveloped to proved developed at the end of the first, second, and third quarters for use in determining a DD&A rate for the quarter.

     In accordance with SFAS No. 144,“Accounting for the Impairment or Disposal of Long-Lived Assets,”(“SFAS 144”) the Company is required to assess the need for an impairment of capitalized costs of long-lived assets to be held and used, including proved oil and natural gas properties, whenever events and circumstances indicate that the carrying value of the asset may not be recoverable. If impairment is indicated based on a comparison of the asset’s carrying value to its undiscounted expected future net cash flows, then it is recognized to the extent that the carrying value exceeds fair value. Expected future net cash flows are

ENCORE ENERGY PARTNERS GP LLC

NOTES TO CONSOLIDATED BALANCE SHEET — Continued

based on existing proved reserve and production information and pricing assumptions that management believes are representative of future economics. Any impairment charge incurred is expensed and reduces the recorded basis in the asset.

     Unproved properties, the majority of the costs of which relate to the acquisition of leasehold interests, are assessed for impairment on a property-by-property basis for individually significant balances and on an aggregate basis for individually insignificant balances. If the assessment indicates an impairment, a loss is recognized by providing a valuation allowance at the level consistent with the level at which impairment was assessed. The impairment assessment is affected by economic factors such as the results of exploration activities, commodity price outlooks, remaining lease terms, and potential shifts in business strategy employed by management. In the case of individually insignificant balances, the amount of the impairment loss recognized is determined by amortizing the portion of these properties’ costs which ENP believes will not be transferred to proved over the average life of the lease.

     Amounts shown in the accompanying Consolidated Balance Sheet as “Proved properties, including wells and related equipment” consisted of the following as of December 31, 2007 (in thousands):

Proved leasehold costs	$	372,076
Wells and related equipment — Completed		124,381
Wells and related equipment — In process		4,013
Total proved properties	$	500,470

     Other Property and Equipment. Other property and equipment is carried at cost. Depreciation is expensed on a straight-line basis over estimated useful lives, which range from three to seven years.

Goodwill and Other Intangible Assets

     The Company accounts for intangible assets under the provisions of SFAS No. 142,“Goodwill and Other Intangible Assets”(“SFAS 142”). Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired in business combinations. Goodwill and other intangible assets with indefinite useful lives are tested for impairment annually, or immediately if conditions indicate that an impairment could exist. If indicators of impairment are determined to exist, an impairment charge is recognized for the amount by which the carrying value of the indefinite lived intangible asset exceeds its implied fair value. Intangible assets with definite useful lives are amortized over their estimated useful lives. In accordance with SFAS 144, the Company evaluates the recoverability of intangible assets with definite useful lives whenever events or changes in circumstances indicate that the carrying value of the asset may not be fully recoverable. An impairment loss exists when estimated undiscounted cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount.

     In connection with the Partnership’s acquisition of the Elk Basin Assets, the Partnership acquired a contract to purchase natural gas at a below market price for use as field fuel. The fair value of this contract, net of related amortization, is shown as “Other intangibles, net” on the accompanying Consolidated Balance Sheet as of December 31, 2007. The value of this contract is amortized on a straight-line basis over its estimated useful life of approximately 14 years. As of December 31, 2007, the gross carrying amount of the contract was $4.2 million and accumulated amortization was $0.3 million.

Asset Retirement Obligations

     SFAS No. 143,“Accounting for Asset Retirement Obligations”requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which the liability is incurred. For oil and natural gas properties, this is the period in which an oil or natural gas well is acquired or drilled. An amount equal to and offsetting the asset retirement obligation is capitalized as part of the carrying amount of the Company’s oil and natural gas properties. The liability is recorded at its discounted fair value and then accreted each period until it is settled or the well is sold, at which time the liability is reversed. Estimates are based on historical experience in plugging and abandoning wells and estimated remaining field life based on reserve estimates. See “Note 5. Asset Retirement Obligations” for additional information.

Environmental Costs

     The Company capitalizes or expenses environmental expenditures, as appropriate, depending on whether the expenditure has a future economic benefit. Expenditures that relate to an existing condition caused by past operations and that have no future economic benefit are expensed. Liabilities for such expenditures are recorded on an undiscounted basis when environmental assessments or clean-ups are probable and the costs can be reliably estimated. Expenditures that extend the life of the related property or mitigate or prevent future environmental contamination are capitalized.

Unit-Based Compensation

     The Partnership does not have any employees. However, the ENP Incentive Plan provides for the grant of unit awards and unit-based awards for employees, consultants, and directors of EAC, the General Partner, and any of their affiliates that perform services for the Partnership. In addition, in May 2007, the board of directors of the General Partner (the “Board of Directors”) issued 550,000 management incentive units to certain of its executive officers.

     The Company accounts for unit-based compensation according to the provisions of SFAS No. 123 (revised 2004),“Share-Based Payment”(“SFAS 123R”). SFAS 123R requires the recognition of compensation expense, over the requisite service period, in an amount equal to the fair value of unit-based payments granted. See “Note 8. Unit-Based Compensation Plans” for additional discussion of the Company’s unit-based compensation plans.

Income Taxes

     The General Partner is not a taxable entity for federal and state income tax purposes. The General Partner is included in the consolidated return of its parent, EAC, and the tax on the General Partner’s income is borne by EAC.

     ENP is treated as a partnership for federal and state income tax purposes with each partner being separately taxed on his share of the Partnership’s taxable income. However, in May 2006, the state of Texas enacted a new business tax (the “Texas Margin Tax”) that replaced the Texas franchise tax. The Texas Margin Tax is applicable to numerous types of entities that previously were not subject to the franchise tax. In 2006, a deferred tax liability was recognized for the expected future tax effect of the Texas Margin Tax due to the difference between the book and tax bases of the Partnership’s properties located in Texas.

     On January 1, 2007, ENP adopted the provisions of Financial Accounting Standards Board (“FASB”) Interpretation (“FIN”) No. 48,“Accounting for Uncertainty in Income Taxes — an Interpretation of FASB Statement No. 109”(“FIN 48”). FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an entity’s financial statements in accordance with SFAS No. 109,“Accounting for Income Taxes.”FIN 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The adoption of FIN 48 did not have an impact on the Company’s consolidated balance sheet.

Revenue Recognition

     Revenues are recognized for the Company’s share of jointly owned properties as oil and natural gas is produced and sold, net of royalties. Natural gas revenues are also reduced by any processing and other fees paid, except for transportation costs paid to third parties. Natural gas revenues are recorded using the sales method of accounting, whereby revenue is recognized based on actual sales of natural gas rather than based on the entity’s proportionate share of natural gas production. Royalties and severance taxes are paid based upon the actual price received from the sales. To the extent actual quantities and values of oil and natural gas are unavailable for a given reporting period because of timing or information not received from third parties, the expected sales volumes and values for those properties are estimated and recorded as accounts receivable in the accompanying Consolidated Balance Sheet. If the Company’s overproduced imbalance position (i.e., the Company has cumulatively been over-allocated production) is greater that the Company’s share of remaining reserves, a liability is recorded for the excess at period-end prices. The Company does not recognize revenue for the production in tanks, oil marketed on behalf of joint owners in the Company’s oil and natural gas properties, or oil in pipelines that has not been delivered to the purchaser. Natural gas imbalances as of December 31, 2007 were immaterial. As of December 31, 2007, the Company did not have any oil inventory in pipelines.

Derivatives

     The Partnership uses various financial instruments for non-trading purposes to manage and reduce price volatility and other market risks associated with the Partnership’s oil and natural gas production. These arrangements are structured to reduce the Partnership’s exposure to commodity price decreases, but they can also limit the benefit the Partnership might otherwise receive from commodity price increases. The Partnership’s risk management activity is generally accomplished through over-the-counter forward derivative or option contracts with large financial institutions.

     The Company applies the provisions of SFAS No. 133,“Accounting for Derivative Instruments and Hedging Activities”and its amendments (“SFAS 133”). SFAS 133 requires each derivative instrument to be recorded in the balance sheet as either an asset or liability measured at fair value. The Partnership has elected to not designate its portfolio of commodity derivatives as hedges and records mark-to-market gains or losses through the income statement each quarter.

New Accounting Pronouncements

SFAS No. 157, “Fair Value Measurements” (“SFAS 157”)

     In September 2006, the FASB issued SFAS 157, which standardizes the definition of fair value, establishes a framework for measuring fair value in generally accepted accounting principles (“GAAP”), and expands disclosures related to the use of fair value measures in financial statements. SFAS 157 applies whenever other standards require (or permit) assets or liabilities to be measured at fair value but does not require any new fair value measurements. In February 2008, the FASB issued FASB Staff Position (“FSP”) No. FAS 157-2,“Effective Date of FASB Statement No. 157”(“FSP FAS 157-2”), which delayed the effective date of SFAS 157 for one year for nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). The Company elected a partial deferral of SFAS 157 for all instruments within the scope of FSP FAS 157-2, including but not limited to, its asset retirement obligations and indefinite lived assets. The Company will continue to evaluate the impact of SFAS 157 on these instruments during the deferral period. The adoption of SFAS 157 on January 1, 2008, as it relates to financial assets and liabilities, did not have a material impact on the Company’s financial condition.

SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities — including an amendment of FASB Statement No. 115” (“SFAS 159”)

     In February 2007, the FASB issued SFAS 159, which permits entities to measure many financial instruments and certain other assets and liabilities at fair value on an instrument-by-instrument basis. SFAS 159 allows entities an irrevocable option to measure eligible items at fair value at specified election dates, with resulting changes in fair value reported in earnings. SFAS 159 was effective for the Company on January 1, 2008; however, the Company did not elect the fair value option for eligible instruments existing on that date. Therefore, the adoption of SFAS 159 did not have an impact on the Company’s financial condition. In the future, the Company will assess the impact of electing the fair value option for any newly acquired eligible instruments. Electing the fair value option for such instruments could have a material impact on the Company’s financial condition.

FSP on FIN 39-1, “Amendment of FASB Interpretation No. 39” (“FSP FIN 39-1”)

     In April 2007, the FASB issued FSP FIN 39-1, which amends FIN No. 39,“Offsetting of Amounts Related to Certain Contracts”(“FIN 39”), to permit a reporting entity that is party to a master netting arrangement to offset the fair value amounts recognized for the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) against fair value amounts recognized for derivative instruments that have been offset under the same master netting arrangement in accordance with FIN 39. FSP FIN 39-1 is effective for fiscal years beginning after November 15, 2007. The Company adopted FSP FIN 39-1 effective January 1, 2008. The adoption of FSP FIN 39-1 did not have a material impact on its financial condition.

SFAS No. 141 (revised 2007), “Business Combinations” (“SFAS 141R”)

     In December 2007, the FASB issued SFAS 141R, which replaces SFAS No. 141,“Business Combinations.”SFAS 141R establishes principles and requirements for the reporting entity in a business combination, including: (i) recognition and measurement in the financial statements of the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree; (ii) recognition and measurement of goodwill acquired in the business combination or a gain from a bargain purchase; and (iii) determination of the information to be disclosed to enable financial statement users to evaluate the nature and financial effects of the business combination. SFAS 141R applies prospectively to business combinations consummated in fiscal years beginning on or after December 15, 2008 (for acquisitions that close on or after January 1, 2009 for the Company). Early application is prohibited. The Company is evaluating the impact SFAS 141R will have on its financial condition and the reporting of future acquisitions in the Consolidated Balance Sheet.

SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements — an amendment of ARB No. 51” (“SFAS 160”)

     In December 2007, the FASB issued SFAS 160, which amends Accounting Research Bulletin No. 51,“Consolidated Financial Statements”to establish accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. SFAS 160 clarifies that a noncontrolling interest should be presented as a component of equity in the consolidated financial statements and requires consolidated net income to be reported at amounts that include the amounts attributable to both the parent and the noncontrolling interest. In addition, the standard establishes expanded disclosure requirements and addresses changes in a parent’s ownership of a noncontrolling interest, changes in a parent’s ownership interest while the parent retains its controlling financial interest, and fair value measurement of any retained noncontrolling interest investment. SFAS 160 is effective for financial statements issued for fiscal years beginning on or after December 15, 2008, and interim periods within those fiscal years. The Company does not expect the adoption of SFAS 160 to have a material impact on its financial condition.

SFAS No. 161, “Disclosures about Derivative Instruments and Hedging Activities — an amendment of FASB Statement No. 133” (“SFAS 161”)

     In March 2008, the FASB issued SFAS 161, which amends SFAS 133 to require enhanced disclosures about (i) how and why an entity uses derivative instruments; (ii) how derivative instruments and related hedged items are accounted for under SFAS 133 and its related interpretations; and (iii) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. SFAS 161 is effective for fiscal years beginning on or after November 15, 2008, with early application encouraged. The adoption of SFAS 161 will require additional disclosures regarding the Company’s derivative instruments; however, SFAS 161 will not change the Company’s accounting for its derivative instruments and therefore, will not have an impact on the Company’s financial condition.

SFAS No. 162, “The Hierarchy of Generally Accepted Accounting Principles” (“SFAS 162”)

     In May 2008, the FASB issued SFAS 162, which identifies the sources of accounting principles and the framework for selecting the principles to be used in the preparation of financial statements of nongovernmental entities that are presented in conformity with GAAP. SFAS 162 is effective 60 days following the Securities and Exchange Commission’s (the “SEC”) approval of the Public Company Accounting Oversight Board amendments to AU Section 411,“The Meaning of Present Fairly in Conformity with Generally Accepted Accounting Principles.”The Company does not expect the adoption of SFAS 162 to change its current accounting practice; therefore, the adoption of SFAS 162 will not have an impact on the Company’s financial condition.

Note 3. Acquisition

     In January 2007, EAC entered into a purchase and sale agreement with certain subsidiaries of Anadarko Petroleum Corporation (“Anadarko”) to acquire oil and natural gas properties and related assets in the Big Horn Basin of Wyoming and Montana, which included the Elk Basin Assets. Prior to closing, EAC assigned the rights and duties under the purchase and sale agreement relating to the Elk Basin Assets to OLLC. The closing of the acquisition occurred in March 2007. The total purchase price for the Elk Basin Assets was approximately $330.7 million, including transaction costs of approximately $1.1 million.

     The following displays the calculation of the total purchase price and the allocation to the fair value of the assets acquired and liabilities assumed from Anadarko as of December 31, 2007 (in thousands):

Calculation of total purchase price:
Cash paid to Anadarko	$	329,551
Transaction costs		1,110
Total purchase price	$	330,661
Allocation of purchase price to the fair value of net assets acquired:
Proved properties, including wells and related equipment	$	332,549
Intangibles		4,225
Other property and equipment		346
Accounts receivable		1,444
Total assets acquired		338,564
Current liabilities		(1,120	)
Future abandoment cost and assumed liabilities		(6,783	)
Total liabilities assumed		(7,903	)
Fair value of net assets acquired	$	330,661

     The proved properties amount in the above purchase price allocation includes the fair value of proved leasehold costs, lease and well equipment (including flue gas reinjection facilities used to maintain reservoir pressure by compressing and reinjecting the gas produced), and an oil pipeline and natural gas pipeline used primarily to transport production from the acquired fields. Natural gas liquids are produced as a byproduct of the flue gas tertiary recovery project and are sold at market prices.

     The Partnership financed the acquisition of the Elk Basin Assets through a $93.7 million contribution from EAC and borrowings under its long-term debt agreements. See “Note 6. Debt” for additional discussion of the Partnership’s long-term debt.

Note 4. Commitments and Contingencies

     From time to time, the Company is a party to various legal proceedings in the ordinary course of business. The Company is not currently a party to any litigation or pending claims that it believes would have a material adverse effect on its business, financial condition, results of operations, or liquidity.

     Additionally, the Company has contractual obligations related to future plugging and abandonment expenses on oil and natural gas properties and related facilities disposal, long-term debt, and derivative contracts as discussed more fully in these notes.

Note 5. Asset Retirement Obligations

     The Company’s asset retirement obligations relate to future plugging and abandonment expenses on oil and natural gas properties and related facilities disposal. The following table summarizes the changes in the Company’s estimated asset retirement obligations for 2007 (in thousands):

Future abandonment liability at January 1, 2007	$	1,754
Acquisition of properties		6,343
Wells drilled		117
Accretion of discount		371
Plugging and abandonment costs incurred		(103	)
Revision of estimates		222
Future abandonment liability at December 31, 2007	$	8,704

     As of December 31, 2007, approximately $8.3 million of the Company’s asset retirement obligations was long-term and recorded in “Future abandonment cost, net of current portion” and $0.4 million was current and included in “Other current liabilities” in the accompanying Consolidated Balance Sheet.

     Approximately $4.4 million of the future abandonment liability as of December 31, 2007 represents the cost for decommissioning the Elk Basin natural gas processing plant. The Company expects to continue reserving additional amounts based on the estimated timing to cease operations of the natural gas processing plant. In addition to the future abandonment liability for the Elk Basin plant, as of December 31, 2007, the Company had recorded an estimated liability of $1.0 million related to required environmental plant compliance costs caused by past operations of the plant. The liability was assumed from Anadarko in the acquisition of the Elk Basin Assets. The liability was estimated based on directives from the Bureau of Land Management for required cleanup of environmental contamination.

Note 6. Debt

Revolving Credit Facility

     In conjunction with the closing of the acquisition of the Elk Basin Assets on March 7, 2007, OLLC entered into a five-year credit agreement (as amended, the “OLLC Credit Agreement”) with a bank syndicate comprised of Bank of America, N.A. and other lenders. The OLLC Credit Agreement provides for revolving credit loans to be made to OLLC from time to time and letters of credit to be issued from time to time for the account of OLLC or any of its restricted subsidiaries. The OLLC Credit Agreement matures on March 7, 2012.

     The aggregate amount of the commitments of the lenders under the OLLC Credit Agreement is $300 million. Availability under the OLLC Credit Agreement is subject to a borrowing base, which is redetermined semi-annually and upon requested special redeterminations. At December 31, 2007, the borrowing base was $145 million.

     OLLC’s obligations under the OLLC Credit Agreement are secured by a first-priority security interest in OLLC’s and its restricted subsidiaries’ proved oil and natural gas reserves and in the equity interests of OLLC and its restricted subsidiaries. In addition, OLLC’s obligations under the OLLC Credit Agreement are guaranteed by the Partnership and OLLC’s restricted subsidiaries. Obligations under the OLLC Credit Agreement are non-recourse to EAC and its restricted subsidiaries.

     Loans under the OLLC Credit Agreement are subject to varying rates of interest based on (i) the total amount outstanding in relation to the borrowing base and (ii) whether the loan is a Eurodollar loan or a base rate loan. Eurodollar loans bear interest at the Eurodollar rate plus the applicable margin indicated in the following table, and base rate loans bear interest at the base rate plus the applicable margin indicated in the following table:

	Applicable Margin for			Applicable Margin for
Ratio of Total Outstanding Borrowings to Borrowing Base	Eurodollar Loans			Base Rate Loans
Less than .50 to 1		1.000	%		0.000	%
Greater than or equal to .50 to 1 but less than .75 to 1		1.250	%		0.000	%
Greater than or equal to .75 to 1 but less than .90 to 1		1.500	%		0.250	%
Greater than or equal to .90 to 1		1.750	%		0.500	%

     The “Eurodollar rate” for any interest period (either one, two, three, or six months, as selected by the Partnership) is the rate per year equal to the London Interbank Offered Rate (“LIBOR”), as published by Reuters or another source designated by Bank of America, N.A., for deposits in dollars for a similar interest period. The “base rate” is calculated as the higher of (i) the annual rate of interest announced by Bank of America, N.A. as its “prime rate” and (ii) the federal funds effective rate plus 0.5 percent.

NOTES TO CONSOLIDATED BALANCE SHEET — Continued

     As of December 31, 2007, the aggregate principal amount of loans outstanding under the OLLC Credit Agreement was $47.5 million and there were $0.1 million of outstanding letters of credit. Outstanding letters of credit reduce the availability under the OLLC Credit Agreement. Borrowings under the OLLC Credit Agreement may be repaid from time to time without penalty.

     The OLLC Credit Agreement contains covenants that include, among others:

• a prohibition against incurring debt, subject to permitted exceptions;

• a prohibition against purchasing or redeeming capital stock, or prepaying indebtedness, subject to permitted exceptions;

• a restriction on creating liens on the assets of the Partnership, OLLC and its restricted subsidiaries, subject to permitted exceptions;

• restrictions on merging and selling assets outside the ordinary course of business;

• restrictions on use of proceeds, investments, transactions with affiliates, or change of principal business;

• a provision limiting oil and natural gas hedging transactions (other than puts) to a volume not exceeding 75 percent of anticipated production from proved producing reserves;

• a requirement that OLLC maintain a ratio of consolidated current assets to consolidated current liabilities of not less than 1.0 to 1.0;

• a requirement that OLLC maintain a ratio of consolidated EBITDA (as defined in the OLLC Credit Agreement) to the sum of consolidated net interest expense plus letter of credit fees of not less than 1.5 to 1.0;

• a requirement that OLLC maintain a ratio of consolidated EBITDA (as defined in the OLLC Credit Agreement) to consolidated senior interest expense of not less than 2.5 to 1.0; and

• a requirement that OLLC maintain a ratio of consolidated funded debt (excluding certain related party debt) to consolidated adjusted EBITDA (as defined in the OLLC Credit Agreement) of not more than 3.5 to 1.0.

     The OLLC Credit Agreement contains customary events of default. If an event of default occurs and is continuing, lenders with a majority of the aggregate commitments may require Bank of America, N.A. to declare all amounts outstanding under the OLLC Credit Agreement to be immediately due and payable. At December 31, 2007, OLLC was in compliance with all debt covenants under the OLLC Credit Agreement.

     OLLC incurs a commitment fee on the unused portion of the OLLC Credit Agreement determined based on the ratio of amounts outstanding under the OLLC Credit Agreement to the borrowing base in effect on such date. The following table summarizes the calculation of the commitment fee under the OLLC Credit Agreement:

	Commitment
Ratio of Total Outstanding Borrowings to Borrowing Base	Fee Percentage
Less than .50 to 1		0.250	%
Greater than or equal to .50 to 1 but less than .75 to 1		0.300	%
Greater than or equal to .75 to 1		0.375	%

Subordinated Credit Agreement

     On March 7, 2007, OLLC entered into a six-year subordinated credit agreement with EAP Operating, LLC, a Delaware limited liability company and direct wholly owned subsidiary of EAC. Pursuant to the subordinated credit agreement, a single subordinated term loan was made on March 7, 2007 to the Partnership in the aggregate amount of $120 million. The total outstanding balance of $126.4 million, including accrued interest, was repaid using a portion of the net proceeds from the IPO.

Long-Term Debt Maturities

     The following table illustrates the Partnership’s long-term debt maturities at December 31, 2007:

	Payments Due by Period

Note 7. Owner’s Net Equity and Distributions

     ENP’s partnership agreement requires that, within 45 days after the end of each quarter, it distribute all of its available cash (as defined in the partnership agreement) to its unitholders. Distributions are not cumulative. The Partnership distributes available cash to its unitholders and the General Partner in accordance with their ownership percentages. In distributing available cash, the Partnership assumes that the holders of management incentive units own the equivalent number of common units into which such units are convertible on the date of distribution, provided that distributions payable to holders of management incentive units are subject to a maximum limit equal to 5.1 percent of all distributions to the Partnership’s unitholders at the time of any such distribution. If the 5.1 percent maximum limit on aggregate distributions to the holders of management incentive units is reached, then any available cash that would have been distributed to such holders will be available for distribution to unitholders. See “Note 8. Unit-Based Compensation Plans” for additional discussion of the management incentive units.

     On November 14, 2007, the Partnership paid a prorated quarterly distribution of $0.053 per unit for the period from and including September 17, 2007 (the closing date of the IPO) through September 30, 2007. The total distribution of $1.3 million was paid to unitholders of record as of the close of business on November 8, 2007.

Note 8. Unit-Based Compensation Plans

Management Incentive Units

     In May 2007, the Board of Directors issued 550,000 management incentive units to certain of its executive officers. A management incentive unit is a limited partner interest in the Partnership that entitles the holder to quarterly distributions to the extent paid to the Partnership’s common unitholders and to increasing distributions upon the achievement of 10 percent compounding increases in the Partnership’s distribution rate to common unitholders. A management incentive unit is also convertible into common units upon the occurrence of certain events. The management incentive units are subject to a maximum limit on the aggregate number of common units issuable to, and the aggregate distributions payable to, holders of management incentive units as follows:

• the holders of management incentive units are not entitled to receive, in the aggregate, common units upon conversion of the management incentive units that exceed a maximum limit of 5.1 percent of all the Partnership’s then-outstanding units; and

• the holders of management incentive units are not entitled to receive, in the aggregate, distributions of the Partnership’s available cash in an amount that exceeds a maximum limit of 5.1 percent of all such distributions to all unitholders at the time of any such distribution.

     The holders of management incentive units do not have any voting rights with respect to the units. The management incentive units vest in three equal installments. The first installment vested upon the closing of the IPO, and the subsequent vestings occur on September 17, 2008 and 2009. As of December 31, 2007, the Company had $4.8 million of total unrecognized compensation cost related to unvested, outstanding management incentive units, which is expected to be recognized over a weighted average period of 0.7 years. There have not been any additional issuances or forfeitures of management incentive units.

ENP Incentive Plan

     As discussed in “Note 1. Formation of the Company and Description of Business,” in connection with the IPO, the Board of Directors adopted the ENP Incentive Plan for employees, consultants, and directors of EAC, the General Partner, and any of their affiliates who perform services for the Partnership. The ENP Incentive Plan provides for the grant of options, restricted units, phantom units, unit appreciation rights, distribution equivalent rights, other unit-based awards, and unit awards. An aggregate of 1,150,000 common units may be delivered pursuant to awards under the ENP Incentive Plan. As of December 31, 2007, there were 1,130,000 units available for issuance under the ENP Incentive Plan. The ENP Incentive Plan is administered by the Board of Directors or a committee thereof, referred to as the plan administrator.

12

ENCORE ENERGY PARTNERS GP LLC

NOTES TO CONSOLIDATED BALANCE SHEET — Continued

     In October 2007, the Board of Directors issued 20,000 phantom units to its directors pursuant to the ENP Incentive Plan. A phantom unit entitles the grantee to receive a common unit upon the vesting of the phantom unit or, at the discretion of the plan administrator, cash equivalent to the value of a common unit. These phantom units are classified as liability awards under SFAS 123R. Accordingly, the Company determines the fair value of these awards at each reporting period, based on the closing unit price of the Partnership’s common units, and recognizes the current portion of the liability as a component of “Other current liabilities” and the long-term portion of the liability as a component of “Other noncurrent liabilities” in the accompanying Consolidated Balance Sheet. As of December 31, 2007, the total liability was approximately $31,000. For liability awards, the fair value of the award, which determines the measurement of the liability on the balance sheet, is remeasured at each reporting period until the award is settled. Changes in the fair value of the liability award from period to period are recorded as increases or decreases in compensation expense, over the remaining service period. The phantom units vest in four equal annual installments beginning on October 29, 2008. The holders of phantom units are also entitled to receive distribution equivalent rights prior to vesting, which entitle the grantee to receive cash equal to the amount of any cash distributions made by the Partnership with respect to a common unit during the period the right is outstanding.

     There were no additional issuances or forfeitures under the ENP Incentive Plan during 2007.

     To satisfy common unit awards, the Partnership may issue new common units, acquire common units in the open market, or use common units already owned by EAC and its affiliates.

Note 9. Financial Instruments

     The carrying value of the Company’s cash, accounts receivable, and accounts payable approximate their respective fair value due to the relatively short term of the instruments. The carrying amount of long-term debt approximates fair value as the interest rate is variable. Commodity derivative contracts are marked-to-market each quarter in accordance with the provisions of SFAS 133.

Derivative Financial Instruments

     The Partnership manages commodity price risk with swap contracts, put contracts, collars, and floor spreads. Swap contracts provide a fixed price for a notional amount of volume. Put contracts provide a fixed floor price on a notional amount of volume while allowing full price participation if the relevant index price closes above the floor price. Collar contracts provide a floor price for a notional amount of volume while allowing some additional price participation if the relevant index price closes above the floor price.

     In connection with the acquisition of the Elk Basin Assets, EAC purchased floor contracts for 2,500 Bbls per day (“Bbls/D”) of production at $65.00 per Bbl for April 2007 through December 2008 that were all later contributed to the Partnership at their fair market value on the date of transfer of $9.4 million. In addition to these contributed derivatives, the Partnership has purchased additional derivative financial instruments as part of its risk management strategy.

     Commodity Contracts — Mark-to-Market Accounting.In order to partially finance the cost of premiums on certain purchased floors, the Partnership may sell floors with a strike price below the strike price of the purchased floor. Together the two floors, known as a floor spread or put spread, have a lower premium cost than a traditional floor contract but provide price protection only down to the strike price of the short floor. During 2007, the Partnership entered into floor spreads with a $75 per

14

ENCORE ENERGY PARTNERS GP LLC

NOTES TO CONSOLIDATED BALANCE SHEET — Continued

Bbl purchased floor and a $65 per Bbl short floor for 2,000 Bbls/D in 2008 and 2010 and 1,250 Bbls/D in 2009. As with the Partnership’s other derivative contracts, these are marked-to-market each quarter. In the above table, the purchased floor component and the short floor component of these floor spreads are shown net and included with the Partnership’s other floor contracts. The net cash flows per Bbl upon settlement of the contracts and payment of the related premiums when viewed together change depending on the NYMEX oil price as follows:

• When the NYMEX oil price is greater than $75 per Bbl, the Partnership pays the net purchased floor premium cost per Bbl.

• When the NYMEX oil price is greater than $65 per Bbl but less than $75 per Bbl, the Partnership receives settlements of $75 per Bbl less the NYMEX oil price and pays the net purchased floor premium cost per Bbl.

• When the NYMEX oil price is below $65 per Bbl, the Partnership receives $10 per Bbl less the net purchased floor premium cost per Bbl.

     Counterparty Risk.At December 31, 2007, the Partnership had committed greater than 10 percent of either its oil or natural gas production represented by derivative contracts to the following counterparties:

	Percentage of			Percentage of
	Oil Derivative			Natural Gas
	Contracts			Derivative Contracts
Counterparty	Committed			Committed
Bank of America, N.A.		37.6	%		—
BNP Paribas		40.4	%		23.3	%
Calyon		5.7	%		17.8	%
Wachovia		2.5	%		58.9	%

     The Partnership believes the credit-worthiness of its counterparties is sound and does not anticipate any non-performance of contractual obligations. As long as each counterparty maintains an investment grade credit rating, pursuant to ENP’s derivative contracts, no collateral is required.

     In order to mitigate the credit risk of financial instruments, ENP enters into master netting agreements with significant counterparties. The master netting agreement is a standardized, bilateral contract between a given counterparty and ENP. Instead of treating separately each financial transaction between the counterparty and ENP, the master netting agreement enables the counterparty and ENP to aggregate all financial trades and treat them as a single agreement. This arrangement benefits ENP in three ways: (i) the netting of the value of all trades reduces the requirements of daily collateral posting by ENP, (ii) default by a counterparty under one financial trade can trigger rights to terminate all financial trades with such counterparty, and (iii) netting of settlement amounts reduces ENP’s credit exposure to a given counterparty in the event of close-out.

Note 10. Related Party Transactions

     The Partnership does not have any employees. The employees supporting the operations of the Partnership are employees of EAC. As discussed in “Note 1. Formation of the Company and Description of Business,” at the closing of the IPO, the Partnership entered into the Administrative Services Agreement with Encore Operating, pursuant to which Encore Operating performs administrative services for the Partnership. Under the Administrative Services Agreement, Encore Operating initially received an administrative fee of $1.75 per BOE of the Partnership’s production for such services and reimbursement for actual third-party expenses incurred on the Partnership’s behalf. The Partnership also pays its share of expenses that are directly chargeable to wells under joint operating agreements. In addition, Encore Operating is entitled to retain any COPAS overhead charges associated with drilling and operating wells that would otherwise be paid by non-operating interest owners to the operator of a well. Encore Operating is not liable to the Partnership for its performance of, or failure to perform, services under the Administrative Services Agreement unless its acts or omissions constitute gross negligence or willful misconduct.

     In 2007, the Partnership paid $2.8 million to Encore Operating for administrative fees under the Administrative Services Agreement (including payment of any COPAS recovery) and $3.5 million for reimbursement of actual third-party expenses incurred on the Partnership’s behalf. As of December 31, 2007, the Partnership had a payable to EAC of $6.7 million for services provided by Encore Operating, which is reflected in “Accounts payable — affiliate” in the accompanying Consolidated

NOTES TO CONSOLIDATED BALANCE SHEET — Continued

Balance Sheet. As of December 31, 2007, the Company had a receivable from EAC of $3.3 million, which is reflected in “Accounts receivable — affiliate” in the accompanying Consolidated Balance Sheet.

     During 2007, the Partnership distributed approximately $0.8 million to EAC and certain executive officers of the General Partner related to the third quarter distribution on common units and management incentive units. In addition, the Partnership distributed approximately $27,000 to the General Partner as the holder of 504,851 general partner units.

     As discussed in “Note 6. Debt,” the Partnership used a portion of the net proceeds from the IPO to repay in full the subordinated credit agreement held by a related party of the Partnership.

     EAC (through its subsidiaries) contributed $93.7 million to the Partnership in March 2007. These proceeds were used by the Partnership, along with proceeds from the borrowings under the Partnership’s long-term debt agreements, to purchase the Elk Basin Assets. Additionally, EAC (through its subsidiaries) made a non-cash contribution in March 2007 of derivative oil put contracts representing 2,500 Bbls/D of production at $65.00 per Bbl for the period of April 2007 through December 2008. At the date of transfer, the derivative contracts had a fair value of $9.4 million.

Note 11. Subsequent Events — Unaudited

Acquisitions

     As discussed in “Note 2. Summary of Significant Accounting Policies,” in February 2008, the Partnership completed the acquisition of the Permian and Williston Basin Assets from Encore Operating. The total consideration for the acquisition consisted of approximately $125.3 million in cash and 6,884,776 common units representing limited partner interests in the Partnership, which were valued at $125 million. Upon completion of the acquisition, the borrowing base under OLLC’s revolving credit facility was increased to $240 million. The Partnership financed the cash portion of the purchase price through additional borrowings under the OLLC Credit Agreement. The acquisition was accounted for as a transaction between entities under common control. Therefore, the assets and liabilities were recorded on the Company’s balance sheet at Enocre Operating’s historical basis, and the historical financial position of the Company has been recast to reflect the historical financial position of the combined entities. Upon completion of the acquisition, the General Partner owned a general partner interest of approximately 1.6 percent in the Partnership.

     In May 2008, the Partnership acquired an existing net profits interest in certain of its properties in the Permian Basin of West Texas in exchange for 283,700 common units representing limited partner interests in the Partnership. The issued units were valued at approximately $5.8 million.

     During the first quarter of 2008, the Partnership entered into interest rate swap agreements whereby it swapped $100 million of floating rate debt on OLLC’s revolving credit facility to a weighted average fixed rate of 3.06 percent and an expected margin of 1.25 percent. These interest rate swap agreements were designated as cash flow hedges. The following table summarizes the Partnership’s open interest rate swap agreements as of September 16, 2008:

	Notional		Fixed			Floating
Term	Amount		Rate			Rate
	(in thousands)
Sept. 2008 - Jan. 2011	$	50,000		3.1610	%	1 month LIBOR
Sept. 2008 - Jan. 2011		25,000		2.9650	%	1 month LIBOR
Sept. 2008 - Jan. 2011		25,000		2.9613	%	1 month LIBOR

Distributions

     In May 2008, the Board of Directors approved a new distribution methodology for the Partnership, which returns additional cash flow to the Partnership’s unitholders during high commodity price environments. The Partnership will distribute to unitholders 50 percent of the excess distributable cash flow above (i) maintenance capital requirements; (ii) an implied minimum quarterly distribution of $0.4325 per unit, or $1.73 per unit annually; and (iii) a minimum coverage ratio of 1.10.

     During the eight months ended August 31, 2008, the Partnership paid approximately $52.3 million to unitholders for quarterly distributions, of which $0.8 million was paid to the General Partner and had no impact on the Company’s consolidated cash.

Other Events

     Effective April 1, 2008, the administrative fee paid to Encore Operating under the Administrative Services Agreement increased from $1.75 to $1.88 per BOE of the Partnership’s production as a result of the COPAS Wage Index Adjustment for 2008.

     During the first quarter of 2008, the Board of Directors issued 5,000 phantom units to a new board member pursuant to the ENP Incentive Plan.

Capitalized Costs and Costs Incurred Relating to Oil and Natural Gas Producing Activities

     The capitalized cost of oil and natural gas properties was as follows as of December 31, 2007 (in thousands):

Properties and equipment, at cost — successful efforts method:
Proved properties, including wells and related equipment	$	500,470
Unproved properties		298
Accumulated depletion, depreciation, and amortization		(63,295	)
	$	437,473

     The following table summarizes costs incurred related to oil and natural gas properties for the year ended December 31, 2007 (in thousands):

Acquisitions:
Proved properties	$	353,985
Unproved properties		105
Asset retirement obligations		6,343
Total acquisitions		360,433

Oil & Natural Gas Producing Activities — Unaudited

     The estimates of the Partnership’s proved oil and natural gas reserves, which are located entirely within the United States, were prepared in accordance with guidelines established by the SEC and the FASB. Proved oil and natural gas reserve quantities are derived from estimates prepared by petroleum engineers.

     Future prices received for production and future production costs may vary, perhaps significantly, from the prices and costs assumed for purposes of these estimates. There can be no assurance that the proved reserves will be developed within the periods assumed or that prices and costs will remain constant. Actual production may not equal the estimated amounts used in the preparation of reserve projections. In accordance with SEC guidelines, estimates of future net cash flows from ENP’s properties and the representative value thereof are made using oil and natural gas prices in effect as of the dates of such estimates and are held constant throughout the life of the properties. Year-end prices used in estimating net cash flows were as follows as of December 31, 2007:

Oil (per Bbl)	$	96.01
Natural gas (per Mcf)	$	7.47

     Net future cash inflows have not been adjusted for commodity derivative contracts outstanding at the end of the year. The future cash flows are reduced by estimated production costs and development costs, which are based on year-end economic conditions and held constant throughout the life of the properties, and by the estimated effect of future income taxes due to the Texas Margin Tax. Future federal income taxes have not been deducted from future net revenues in the calculation of the Partnership’s standardized measure as each partner is separately taxed on his share of the Partnership’s taxable income.

SUPPLEMENTARY INFORMATION — Continued

     There are numerous uncertainties inherent in estimating quantities of proved reserves and in projecting future rates of production and timing of development expenditures. Oil and natural gas reserve engineering is and must be recognized as a subjective process of estimating underground accumulations of oil and natural gas that cannot be measured in any exact way, and estimates of other engineers might differ materially from those included herein. The accuracy of any reserve estimate is a function of the quality of available data and engineering, and estimates may justify revisions based on the results of drilling, testing, and production activities. Accordingly, reserve estimates are often materially different from the quantities of oil and natural gas that are ultimately recovered. Reserve estimates are integral to management’s analysis of impairments of oil and natural gas properties and the calculation of DD&A on these properties.

     Estimated net quantities of proved oil and natural gas reserves of the Partnership were as follows as of December 31, 2007:

Proved reserves:
Oil (MBbls)	21,397
Natural gas (MMcf)	61,207
Combined (MBOE)	31,598
Proved developed reserves:
Oil (MBbls)	19,140
Natural gas (MMcf)	51,288
Combined (MBOE)	27,688

     The changes in proved reserves were as follows for 2007:

				Natural			Oil
	Oil			Gas			Equivalent
	(MBbls)			(MMcf)			(MBOE)
Balance, December 31, 2006		3,952			55,241			13,159
