GLOSSARY OF TERMS

Bbl. One stock tank barrel or 42 U.S. gallons liquid volume.

Bcf. Billion cubic feet.

Boe. One barrel of oil equivalent, determined using a ratio of six Mcf of natural gas to one Bbl of crude oil, condensate or natural gas liquids.

Boe/d. Barrels of oil equivalent per day.

Btu. British thermal unit, which is the heat required to raise the temperature of a one-pound mass of water from 58.5 to 59.5 degrees Fahrenheit.

Developed acreage. The number of acres that are allocated or assignable to productive wells or wells capable of production.

Development project. A drilling or other project which may target proven reserves, but which generally has a lower risk than that associated with exploration projects.

Development well. A well drilled within the proved area of an oil or natural gas reservoir to the depth of a stratigraphic horizon known to be productive.

Dry hole or well. A well found to be incapable of producing hydrocarbons in sufficient quantities such that proceeds from the sale of such production would exceed production expenses and taxes.

Field. An area consisting of a single reservoir or multiple reservoirs all grouped on or related to the same individual geological structural feature and/or stratigraphic condition.

Gross acres or gross wells. The total acres or wells, as the case may be, in which a working interest is owned.

Hydrocarbons. Oil, NGL and natural gas are all collectively considered hydrocarbons.

Liquids. Oil and NGLs.

MBbls. One thousand barrels of crude oil or other liquid hydrocarbons.

MBoe. One thousand barrels of crude oil equivalent, using a ratio of six Mcf of natural gas to one Bbl of crude oil, condensate or natural gas liquids.

Mcf. One thousand cubic feet.

MGal. One thousand gallons of natural gas liquids or other liquid hydrocarbons.

MMBbls. One million barrels of crude oil or other liquid hydrocarbons.

MMBoe. One million barrels of crude oil equivalent, using a ratio of six Mcf of natural gas to one Bbl of crude oil, condensate or natural gas liquids.

MMBtu. One million British thermal units.

MMcf. One million cubic feet.

Net acres or net wells. The sum of the fractional working interests owned in gross acres or gross wells, as the case may be.

NGL or natural gas liquids. The combination of ethane, propane, butane and natural gasolines that when removed from natural gas become liquid under various levels of higher pressure and lower temperature.

Page 3

NYMEX. New York Mercantile Exchange.

Oil. Crude oil and condensate.

Productive well. A well that is found to be capable of producing hydrocarbons in sufficient quantities such that proceeds from the sale of such production exceed production expenses and taxes.

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

Proved developed non-producing or PDNPs. Proved oil and natural gas reserves that are developed behind pipe, shut-in or that can be recovered through improved recovery only after the necessary equipment has been installed, or when the costs to do so are relatively minor. Shut-in reserves are expected to be recovered from (1) completion intervals which are open at the time of the estimate but which have not started producing, (2) wells that were shut-in for market conditions or pipeline connections, or (3) wells not capable of production for mechanical reasons. Behind-pipe reserves are expected to be recovered from zones in existing wells that will require additional completion work or future re-completion prior to the start of production.

Proved reserves. Proved oil and gas reserves are those quantities of oil and gas, which by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations—prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation.

Proved undeveloped drilling location. A site on which a development well can be drilled consistent with spacing rules for purposes of recovering proved undeveloped reserves.

Proved undeveloped reserves or PUDs. Proved oil and natural gas reserves that are expected to be recovered from new wells on undrilled acreage or from existing wells where a relatively major expenditure is required for re-completion. Reserves on undrilled acreage are limited to those drilling units offsetting productive units that are reasonably certain of production when drilled. Proved reserves for other undrilled units are claimed only where it can be demonstrated with certainty that there is continuity of production from the existing productive formation. Estimates for proved undeveloped reserves are not attributed to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proven effective by actual tests in the area and in the same reservoir.

Re-completion. The completion for production of an existing wellbore in another formation from that which the well has been previously completed.

Reserve acquisition cost. The total consideration paid for an oil and natural gas property or set of properties, which includes the cash purchase price and any value ascribed to units issued to a seller adjusted for any post-closing items.

R/P ratio (reserve life). The reserves as of the end of a period divided by the production volumes for the same period.

Reserve replacement. The replacement of oil and natural gas produced with reserve additions from acquisitions, reserve additions and reserve revisions.

Reserve replacement cost. An amount per Boe equal to the sum of costs incurred relating to oil and natural gas property acquisition, exploitation, development and exploration activities (as reflected in our year-end financial statements for the relevant year) divided by the sum of all additions and revisions to estimated proved reserves, including reserve purchases. The calculation of reserve additions for each year is based upon the reserve report of our independent engineers. Management uses reserve replacement cost to compare our company to others in terms of our historical ability to increase our reserve base in an economic manner. However, past performance does not necessarily reflect future reserve replacement cost performance. For example, increases in oil and natural gas prices in recent years have increased the economic life of reserves, adding additional reserves with no required capital expenditures. On the other hand, increases in oil and natural gas prices have increased the cost of reserve purchases and reserves added through development projects. The reserve replacement cost may not be indicative of the economic value added of the reserves due to differing lease operating expenses per barrel and differing timing of

production.

Reservoir. A porous and permeable underground formation containing a natural accumulation of producible oil and/or natural gas that is confined by impermeable rock or water barriers and is individual and separate from other reserves.

Standardized measure. The present value of estimated future net revenues to be generated from the production of proved reserves, determined in accordance with assumptions required by the Financial Accounting Standards Board and the Securities and Exchange Commission (using the average annual prices based on the un-weighted arithmetic average of the first-day-of-the-month price for each month) without giving effect to non-property related expenses such as general and administrative expenses, debt service and future income tax expenses or to depreciation, depletion and amortization and discounted using an annual discount rate of 10%. Because we are a limited partnership that allocates our taxable income to our unitholders, no provisions for federal or state income taxes have been provided for in the calculation of standardized measure. Standardized measure does not give effect to derivative transactions.

Undeveloped acreage. Lease acreage on which wells have not been drilled or completed to a point that would permit the production of commercial quantities of oil and natural gas regardless of whether such acreage contains proved reserves.

Working interest. The operating interest that gives the owner the right to drill, produce and conduct operating activities on the property and a share of production.

Workover. Operations on a producing well to restore or increase production.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)


(1)	Summary of Significant Accounting Policies


(a)	Organization, Basis of Presentation and Description of Business

Legacy Reserves LP and its affiliated entities are referred to as Legacy, LRLP or the Partnership in these financial statements.

Certain information and footnote disclosures normally included in the financial statements prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) have been condensed or omitted in this Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These condensed consolidated financial statements should be read in connection with the consolidated financial statements and notes thereto included in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2011 .

LRLP, a Delaware limited partnership, was formed by its general partner, Legacy Reserves GP, LLC (“LRGPLLC”), on October 26, 2005 to own and operate oil and natural gas properties. LRGPLLC is a Delaware limited liability company formed on October 26, 2005, and owns an approximate 0.04% general partner interest in LRLP.

Significant information regarding rights of the limited partners includes the following:

• Right to receive, within 45 days after the end of each quarter, distributions of available cash, if distributions are declared.

• No limited partner shall have any management power over LRLP’s business and affairs; the general partner shall conduct, direct and manage LRLP’s activities.

• The general partner may be removed if such removal is approved by the unitholders holding at least 66 2/3 percent of the outstanding units, including units held by LRLP’s general partner and its affiliates, provided that a unit majority has elected a successor general partner.

• Right to receive information reasonably required for tax reporting purposes within 90 days after the close of the calendar year.

In the event of liquidation, all property and cash in excess of that required to discharge all liabilities will be distributed to the unitholders and LRLP’s general partner in proportion to their capital account balances, as adjusted to reflect any gain or loss upon the sale or other disposition of Legacy’s assets in liquidation.

Legacy owns and operates oil and natural gas producing properties located primarily in the Permian Basin (West Texas and Southeast New Mexico), Mid-Continent and Rocky Mountain regions of the United States. Legacy has acquired oil and natural gas producing properties and undrilled leaseholds.

The accompanying condensed consolidated financial statements have been prepared on the accrual basis of accounting whereby revenues are recognized when earned, and expenses are recognized when incurred. These condensed consolidated financial statements as of March 31, 2012 and for the three months ended March 31, 2012 and 2011 are unaudited. In the opinion of management, such financial statements include the adjustments and accruals, all of which are of a normal recurring nature, which are necessary for a fair presentation of the results for the interim periods. These interim results are not necessarily indicative of results for a full year.


(b)	Accrued Oil and Natural Gas Liabilities

Below are the components of accrued oil and natural gas liabilities as of March 31, 2012 and December 31, 2011 .

(2)	Credit Facility

Previous Credit Agreement: On March 27, 2009, Legacy entered into a three-year secured revolving credit facility with BNP Paribas as administrative agent (the “Previous Credit Agreement”). Borrowings under the Previous Credit Agreement were set to mature on April 1, 2012. The Previous Credit Agreement permitted borrowings in the lesser amount of (i) the borrowing base, or (ii) $600 million . The borrowing base under the Previous Credit Agreement, initially set at $340 million , was increased to $410 million on March 31, 2010. Under the Previous Credit Agreement, interest on debt outstanding was charged based on Legacy’s selection of a LIBOR rate plus 2.25% to 3.0% , or the alternate base rate (“ABR”) which equaled the highest of the prime rate, the Federal funds effective rate plus 0.50% or LIBOR plus 1.50% , plus an applicable margin between 0.75% and 1.50% .

Current Credit Agreement: On March 10, 2011, Legacy entered into an amended and restated five-year $1 billion secured revolving credit facility with BNP Paribas as administrative agent (the "Current Credit Agreement"). Effective April 20, 2012, Wells Fargo replaced BNP Paribas as administrative agent as a result of the sale of BNP Paribas' energy lending practice to Wells Fargo. Borrowings under the Current Credit Agreement mature on March 10, 2016. The amount available for borrowing at any one time is limited to the borrowing base with a $2 million sub-limit for letters of credit. The borrowing base under the Current Credit Agreement was redetermined and increased to $565 million on March 31, 2012 . The borrowing base is subject to semi-annual re-determinations on April 1 and October 1 of each year. Additionally, either Legacy or the lenders may, once during each calendar year, elect to re-determine the borrowing base between scheduled re-determinations. Legacy also has the right, once during each calendar year, to request the re-determination of the borrowing base upon the proposed acquisition of certain oil and natural gas properties where the purchase price is greater than 10% of the borrowing base. Under the Current Credit Agreement, interest on debt outstanding is charged based on Legacy's selection of a one-, two-, three- or six-month LIBOR rate plus 1.75% to 2.75% , or the ABR which equals the highest of the prime rate, the Federal funds effective rate plus 0.50% or one-month LIBOR plus 1.00% , plus an applicable margin from 0.75% to 1.75% per annum, determined by the percentage of the borrowing base then in effect that is drawn.

The borrowing base permits Legacy to issue up to $500 million in aggregate principal amount of senior notes or new debt issued to refinance senior notes, subject to specified conditions in the Current Credit Agreement, which include that upon the issuance of such senior notes or new debt, the borrowing base will be reduced by an amount equal to (i) in the case of senior notes, 25% of the stated principal amount of the senior notes and (ii) in the case of new debt, 25% of the portion of the new debt that exceeds the original principal amount of the senior notes.

As of March 31, 2012 , Legacy had outstanding borrowings of $333 million at a weighted-average interest rate of 2.58% and approximately $231.9 million of availability remaining under the Current Credit Agreement. For the three month period ended March 31, 2012 , Legacy paid in cash $2.2 million of interest expense on the Current Credit Agreement. Legacy’s Current Credit Agreement also contains covenants that, among other things, require us to maintain specified ratios or conditions as follows:


•	total debt as of the last day of the most recent quarter to EBITDA (as defined in the Current Credit Agreement) in total over the last four quarters of not more than 4.0 to 1.0; and


•	consolidated current assets, as of the last day of the most recent quarter and including the unused amount of the total commitments, to consolidated current liabilities as of the last day of the most recent quarter of not less than 1.0 to 1.0, excluding non-cash assets and liabilities under ASC 815, which includes the current portion of oil, natural gas and interest rate derivatives.

At March 31, 2012 , Legacy was in compliance with all financial and other covenants of the Current Credit Agreement.


(3)	Related Party Transactions

Cary D. Brown, Chairman, President and Chief Executive Officer of LRGPLLC, and Kyle A. McGraw, Director, Executive Vice President and Chief Development Officer of LRGPLLC, own partnership interests which, in turn, own a combined non-controlling 4.16% interest as limited partners in the partnership which owns the building that Legacy occupies. Monthly rent is $33,462 , without respect to property taxes, insurance and operating expenses. The lease expires in September 2015.

Legacy uses Lynch, Chappell and Alsup for some of its legal services. Alan Brown, son of Dale Brown, a director of Legacy, and brother of Cary D. Brown, was a less than ten percent shareholder in this firm until he resigned from his position on September 1, 2011. Legacy paid legal fees during Alan Brown's tenure to this firm of $32,502 for the three months ended March 31, 2011 .

On March 22, 2012, Legacy acquired a 5% working interest in 100,000 acres of prospective Cline Shale acreage from FireWheel Energy, LLC ("FireWheel"), the operator of the properties, for $5.5 million . FireWheel is a private-equity funded oil and natural gas exploration company in which Alan Brown, son of Dale Brown, a director of Legacy, and brother of Cary D. Brown, is a principal. The interests acquired by Legacy were marketed to numerous industry participants and are governed by an industry standard Participation Agreement and Joint Operating Agreement.


(4)	Commitments and Contingencies

From time to time Legacy is a party to various legal proceedings arising in the ordinary course of business. While the outcome of lawsuits cannot be predicted with certainty, except as discussed below, Legacy is not currently a party to any proceeding that it believes could have a potential material adverse effect on its financial condition, results of operations or cash flows.

On April 15, 2011, the Eleventh Court of Appeals (Case No. 11-09-00348-CV), in an appeal styled Raven Resources, LLC, Appellant v. Legacy Reserves Operating, LP, Appellee , on appeal from the 385th District Court, Midland County, Texas, reversed and rendered in part and reversed and remanded in part the trial court’s summary judgment, dated November 10, 2009 (Cause No. CV 46609) (the "Trial Court Summary Judgment"), in favor of Legacy Reserves Operating, LP ("Legacy Operating"), a subsidiary of Legacy Reserves LP. As set forth below, on March 15, 2012, the Court of Appeals affirmed the Trial Court Summary Judgment in favor of Legacy Operating.

In its original petition to the trial court, filed August 15, 2008, Raven Resources, LLC ("Raven") had sought, among other things, a declaratory judgment that the purchase agreement dated July 11, 2007 (the "PSA") providing for the purchase by Legacy Operating of various non-operated oil and natural gas properties and interests primarily in the Permian Basin for $20.3 million , subject to adjustment, was void, as a matter of law, alleging an employee of Raven had forged the signature of David Stewart, Raven's managing member. Raven also asked the trial court to rescind the transaction, and to account for all proceeds received by Legacy Operating since the properties were originally conveyed. Further, Raven alleged that Legacy Operating had failed to pay the full purchase price for the properties as David Stewart had allegedly only been aware of a June 27, 2007 draft of a purchase agreement, which provided for a $26.6 million purchase price, whereas the PSA, following property due diligence and reducing the list of properties to be purchased, contained a reduced purchase price of $20.3 million . Raven alleged that David Stewart, despite having signed 35 assignments incorporating the PSA as well as a certificate acknowledging Mr. Stewart had executed the PSA, was not aware of the revised terms of the PSA, nor the amounts of payments made to Raven until August 27, 2007, when Mr. Stewart purportedly discovered the employee's fraud. With the proceeds received from Legacy at the closing of the transaction on August 3, 2007, Raven had paid its debts and its partners. In addition, Raven alleged that Legacy Operating benefitted from the fraud promulgated by Michael Lee, and asked the trial court for damages in excess of $6 million . Raven does not claim that Legacy knew about the forgery.

Legacy Operating filed a counterclaim for declaratory relief and for money damages based upon indemnity obligations and post-closing adjustments. The trial court granted a partial summary judgment in favor of Legacy Operating, denied a partial summary judgment sought by Raven, and entered a take-nothing judgment against Raven. The trial court severed the counterclaims brought by Legacy Operating.

In its April 15, 2011 ruling (the "Original Opinion"), the Court of Appeals reversed the Trial Court Summary Judgment and rendered judgment that the PSA was void, as a matter of law, and that a void instrument is not subject to ratification.

Page 13

Further, while the Appeals Court held that the incorporation of the PSA into the assignments for the transfer of the properties will not void the assignments, the assignments were not complete in and of themselves in the absence of the terms of the PSA. The Court of Appeals further remanded to the trial court any issues regarding the repayment of the funds advanced by Legacy Operating, as well as any issues regarding any consideration received by Legacy Operating from or related to the properties.

Legacy Operating filed a motion for rehearing on May 11, 2011 (the "Legacy Motion for Rehearing"). On January 12, 2012, the Court of Appeals granted the Legacy Motion for Rehearing, withdrew its former opinion and judgment, and issued a new opinion and judgment which affirmed the judgment of the trial court granting a partial summary judgment in favor of Legacy Operating, denying a partial summary judgment sought by Raven, and entering a take-nothing judgment against Raven.

The Court of Appeals held that, as a matter of law, certain assignments which specifically incorporated the terms of the purchase agreement dated July 11, 2007 providing for the purchase by Legacy Operating from Raven of various non-operated oil and gas properties and interests in the Permian Basin for $20.3 million , constituted valid, enforceable agreements binding upon Raven and Legacy Operating.

Raven did not file a response to the Legacy Motion for Rehearing and the Court of Appeals did not request one. Subsequently, on January 24, 2012, Raven filed a motion for rehearing and on January 26, 2012, the Court of Appeals issued an order withdrawing its opinion and judgment dated January 12, 2012 in order to allow Raven to respond to the Legacy Motion for Rehearing on or before February 10, 2012. On February 10, 2012, Raven filed its response to the Legacy Motion for Rehearing.

On March 15, 2012, the Court of Appeals granted the Legacy Motion for Rehearing, withdrew the Original Opinion and affirmed the trial court's take nothing judgment against Raven. On April 27, 2012, Raven filed a petition for review with the Supreme Court of Texas, requesting that the Supreme Court reverse the Court of Appeals' judgment in every respect except its conclusion that forged documents are void and ineffective and render judgment that Raven was entitled to summary judgment, entitled to rescind the assignments and unwind the transaction. Alternatively, Raven requests that the Supreme Court reverse the Court of Appeals' judgment insofar as it grants Legacy's motion for partial summary judgment and remand the case to the trial court for further proceedings.

At this time, Legacy cannot predict the Texas Supreme Court's action on Raven's petition for review, or the eventual outcome of this matter. Legacy currently believes that any outcome, which may include no payment, the unwinding of the transaction (which Legacy expects would have an effect of less than $6 million) or a payment of approximately $6 million to Raven, will not have a material impact on its financial condition or ability to make cash distributions at expected levels, though it could have a material adverse effect on its net income (loss).

Additionally, Legacy is subject to numerous laws and regulations governing the discharge of materials into the environment or otherwise relating to environmental protection. To the extent laws are enacted or other governmental action is taken that restricts drilling or imposes environmental protection requirements that result in increased costs to the oil and natural gas industry in general, the business and prospects of Legacy could be adversely affected.

Legacy has employment agreements with its officers that specify that if the officer is terminated by Legacy for other than cause or following a change in control, the officer shall receive severance pay ranging from 24 to 36 months salary plus bonus and COBRA benefits, respectively.


(5)	Fair Value Measurements

As defined in ASC 820-10, fair value is the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820-10 requires disclosure that establishes a framework for measuring fair value and expands disclosure about fair value measurements. The statement requires fair value measurements be classified and disclosed in one of the following categories:

Page 14



Level 1:	Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Legacy considers active markets as those in which transactions for the assets or liabilities occur in sufficient frequency and volume to provide pricing information on an ongoing basis.
Level 2:	Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability. This category includes those derivative instruments that Legacy values using observable market data. Substantially all of these inputs are observable in the marketplace throughout the term of the derivative instrument, can be derived from observable data, or are supported by observable levels at which transactions are executed in the marketplace. Instruments in this category include non-exchange traded derivatives such as over-the-counter commodity price swaps and interest rate swaps as well as long-term incentive plan liabilities calculated using the Black-Scholes model to estimate the fair value as of the measurement date.
Level 3:	Measured based on prices or valuation models that require inputs that are both significant to the fair value measurement and less observable from objective sources (i.e. supported by little or no market activity). Legacy’s valuation models are primarily industry standard models that consider various inputs including: (a) quoted forward prices for commodities, (b) time value, and (c) current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Level 3 instruments primarily include derivative instruments, such as natural gas derivative swaps for those derivatives indexed to the West Texas Waha, ANR-Oklahoma and CIG indices, commodity collars and oil swaptions. Although Legacy utilizes third party broker quotes to assess the reasonableness of its prices and valuation techniques, Legacy does not have sufficient corroborating evidence to support classifying these assets and liabilities as Level 2.

As required by ASC 820-10, financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. Legacy’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels.

Fair Value on a Recurring Basis

The following table sets forth by level within the fair value hierarchy Legacy’s financial assets and liabilities that were accounted for at fair value on a recurring basis as of March 31, 2012 :

Legacy estimates the fair values of the swaps based on published forward commodity price curves for the underlying commodities as of the date of the estimate for those commodities for which published forward pricing is readily available. For those commodity derivatives for which forward commodity price curves are not readily available, Legacy estimates, with the assistance of third-party pricing experts, the forward curves as of the date of the estimate. Legacy estimates the option value of the contract floors and ceilings and oil swaptions using an option pricing model which takes into account market volatility, market prices, contract parameters and discount rates based on published LIBOR rates and interest swap rates. Significant changes in the quoted forward prices for commodities and changes in market volatility generally leads to corresponding changes in the fair value measurement of our oil and natural gas derivative contracts. In order to estimate the fair value of our

Page 15

interest rate swaps, Legacy uses a yield curve based on money market rates and interest rate swaps, extrapolates a forecast of future interest rates, estimates each future cash flow, derives discount factors to value the fixed and floating rate cash flows of each swap, and then discounts to present value all known (fixed) and forecasted (floating) swap cash flows. Curve building and discounting techniques used to establish the theoretical market value of interest bearing securities are based on readily available money market rates and interest swap market data. The determination of the fair values above incorporates various factors including the impact of our non-performance risk and the credit standing of the counterparties involved in the Partnership’s derivative contracts. The risk of nonperformance by the majority of the Partnership’s counterparties is mitigated by the fact that such counterparties (or their affiliates) are also bank lenders under the Partnership’s revolving credit facility. In addition, Legacy routinely monitors the creditworthiness of its counterparties including those who are no longer lenders under the revolving credit facility.

The following table sets forth a reconciliation of changes in the fair value of financial assets and liabilities classified as Level 3 in the fair value hierarchy:

Fair Value on a Non-Recurring Basis

Legacy follows the provisions of ASC 820-10 for nonfinancial assets and liabilities measured at fair value on a non-recurring basis. As it relates to Legacy, the statement applies to certain nonfinancial assets and liabilities as may be acquired in a business combination and thereby measured at fair value; impaired oil and natural gas property assessments; and the initial recognition of asset retirement obligations for which fair value is used.

The asset retirement obligation estimates are derived from historical costs as well as management’s expectation of future cost environments. As there is no corroborating market activity to support the assumptions used, Legacy has designated these liabilities as Level 3. A reconciliation of the beginning and ending balances of Legacy’s asset retirement obligation is presented in Note 7.

Assets measured at fair value during the three -month period ended March 31, 2012 include:

(a)

Legacy utilizes ASC 360-10-35 to periodically review oil and natural gas properties for impairment when facts and circumstances indicate that their carrying value may not be recoverable. Legacy compares net capitalized costs of proved oil and natural gas properties to estimated undiscounted future net cash flows using management’s expectations of future oil and natural gas prices. These future price scenarios reflect Legacy’s estimation of future price volatility. During the three -month period ended March 31, 2012 , Legacy incurred impairment charges of $1.3 million as oil and natural gas properties with a net cost basis of $2.7 million were written down to their fair value of $1.4 million . The inputs used by management for the fair value measurements utilized in this review include significant unobservable inputs, and therefore, the fair value measurements employed are classified as Level 3 for these types of assets.

(b)

Legacy utilizes ASC 805-10 to identify and record the fair value of assets and liabilities acquired in a business combination. During the three -month period ended March 31, 2012 , Legacy acquired oil and natural gas properties, inclusive of an unproved acreage acquisition, with a fair value of $7.9 million in 2 individually immaterial transactions. The inputs used by management for the fair value measurements of these acquired oil and natural gas properties include significant unobservable inputs, and therefore, the fair value measurements employed are classified as Level 3 for these types of assets.

The carrying amount of the revolving long-term debt of $333 million as of March 31, 2012 approximates fair value because Legacy's current borrowing rate does not materially differ from market rates for similar bank borrowings. Legacy has classified the revolving long-term debt as a Level 2 item within the fair value hierarchy.


(6)	Derivative Financial Instruments

Commodity derivative transactions

Due to the volatility of oil and natural gas prices, Legacy periodically enters into price-risk management transactions (e.g., swaps, swaptions or collars) for a portion of its oil and natural gas production to achieve a more predictable cash flow, as well as to reduce exposure to price fluctuations. While the use of these arrangements limits Legacy’s ability to benefit from increases in the price of oil and natural gas, it also reduces Legacy’s potential exposure to adverse price movements. Legacy’s arrangements, to the extent it enters into any, apply to only a portion of its production, provide only partial price protection against declines in oil and natural gas prices and limit Legacy’s potential gains from future increases in prices. None of these instruments are used for trading or speculative purposes.

All of these price risk management transactions are considered derivative instruments and are accounted for in accordance with FASB Accounting Standards Codification 815, Disclosures About Derivative Instruments and Hedging Activities ("ASC 815") . These derivative instruments are intended to reduce Legacy’s price risk and may be considered hedges for economic purposes but Legacy has chosen not to designate them as cash flow hedges for accounting purposes. Therefore, all derivative instruments are recorded on the balance sheet at fair value with changes in fair value being recorded in earnings for the three months ended March 31, 2012 and 2011 .

By using derivative instruments to mitigate exposures to changes in commodity prices, Legacy is exposed to credit risk and market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes Legacy, which creates repayment risk. Legacy minimizes the credit or repayment risk in derivative instruments by entering into transactions with high-quality counterparties that are parties to its Current Credit Agreement.

For the three months ended March 31, 2012 and 2011 , Legacy recognized realized and unrealized gains and losses related to its oil and natural gas derivative transactions. The net gain (loss) from derivative activities was as follows:

As of March 31, 2012 , Legacy had the following NYMEX West Texas Intermediate crude oil swaps paying floating prices and receiving fixed prices for a portion of its future oil production as indicated below:



		Average
Calendar Year	Volumes (Bbls)	Price per Bbl	Price Range per Bbl
April-December 2012(a)	1,516,891	$87.37	$67.72	-	$109.20

2016	45,600	$94.53	$91.00	-	$99.85

(a)

On October 6, 2010, as part of an oil swap transaction entered into with a counterparty, Legacy sold two call options to the counterparty that allow the counterparty to extend a swap transaction covering calendar year 2011 to either 2012, 2013 or both calendar years. The counterparty exercised the option covering calendar year 2012 on December 30, 2011 and must exercise or decline the option covering calendar year 2013 on December 31, 2012. As the option was exercised for calendar year 2012, Legacy will pay the counterparty floating prices and receive a fixed price of $98.25 per Bbl on annual notional volumes of 183,000 Bbls ( 137,500 Bbls remaining as of March 31, 2012 ). For calendar year 2013, if exercised, Legacy would pay the counterparty floating prices and receive a fixed price of $98.25 per Bbl on annual notional volumes of 182,500 Bbls in 2013. The premium paid by the counterparty to Legacy for the two call options was in the form of an increase in the fixed price that we received pursuant to the 2011 swap of $98.25 per Bbl on 182,500 Bbls, or 500 Bbls per day, rather than the prevailing market price of approximately $87.00 per Bbl. These additional potential volumes related to the unexercised 2013 option are not reflected in the above table.

As of March 31, 2012 , Legacy had the following NYMEX West Texas Intermediate crude oil derivative collar contracts that combine a long put option or “floor” with a short call option or “ceiling” as indicated below:

As of March 31, 2012 , Legacy had the following NYMEX West Texas Intermediate crude oil derivative three-way collar contracts that combine a long put, a short put and a short call as indicated below:

As of March 31, 2012 , Legacy had the following West Texas Waha natural gas derivative collar contract that combines a long put option or "floor" with a short call option or "ceiling" as indicated below:

Interest rate derivative transactions

Due to the volatility of interest rates, Legacy periodically enters into interest rate risk management transactions in the form of interest rate swaps for a portion of its outstanding debt balance. These transactions allow Legacy to reduce exposure to interest rate fluctuations. While the use of these arrangements limits Legacy’s ability to benefit from decreases in interest rates, it also reduces Legacy’s potential exposure to increases in interest rates. Legacy’s arrangements, to the extent it enters into any, apply to only a portion of its outstanding debt balance, provide only partial protection against interest rate increases and limit Legacy’s potential savings from future interest rate declines. It is never management’s intention to hold or issue derivative instruments for speculative trading purposes. Conditions sometimes arise where actual borrowings are less than notional amounts hedged, which has, and could result in overhedged amounts.

On August 29, 2007, Legacy entered into LIBOR interest rate swaps beginning in October 2007 and extending through November 2011. On January 29, 2009, Legacy revised and extended these LIBOR interest rate swaps. The revised swap transaction had Legacy paying its counterparty fixed rates ranging from 4.09% to 4.11% , per annum, and receiving floating rates on a total notional amount of $54 million . On August 8, 2011 and August 9, 2011, Legacy again revised and extended these LIBOR interest rate swaps. The current swap transaction has Legacy paying its counterparty fixed rates ranging from 3.07% to 3.13% , per annum, and receiving floating rates on a total notional amount of $54 million . These swaps are settled on a monthly basis, beginning in August 2011 and ending in November 2015.

On March 14, 2008, Legacy entered into a LIBOR interest rate swap beginning in April 2008 and extending through April 2011. On January 28, 2009, Legacy revised this LIBOR interest rate swap extending the term through April 2013. The revised swap transaction has Legacy paying its counterparty a fixed rate of 2.65% per annum, and receiving floating rates on a notional amount of $60 million . This swap is settled on a monthly basis, beginning in April 2009 and ending in April 2013. Prior to April 2009, the swap was settled on a quarterly basis.

On October 6, 2008, Legacy entered into two LIBOR interest rate swaps beginning in October 2008 and extending through October 2011. In January 2009, Legacy revised these LIBOR interest rate swaps extending the termination date through October 2013. The revised swap transactions have Legacy paying its counterparties fixed rates ranging from 3.09% to 3.10% , per annum, and receiving floating rates on a total notional amount of $100 million . On August 8, 2011, Legacy further revised one of the aforementioned LIBOR interest rate swaps, extending the termination date through October 2015. The revised swap transaction has Legacy paying its counterparty a fixed rate of 2.50% , per annum, revised from the previous rate of 3.09% , per annum. The revised swaps are settled on a monthly basis, beginning in August 2011 and January 2009, respectively and ending in October 2015 and October 2013, respectively.

On December 16, 2008, Legacy entered into a LIBOR interest rate swap beginning in December 2008 and extending through December 2013. The swap transaction has Legacy paying its counterparty a fixed rate of 2.295% , per annum, and receiving floating rates on a total notional amount of $50 million . The swap is settled on a quarterly basis, beginning in March 2009 and ending in December 2013.

Page 19

On August 8, 2011, Legacy entered into two LIBOR interest rate swaps, beginning in August 2011 and extending through August 2014. The swap transactions have Legacy paying its counterparties fixed rates ranging from 0.702% to 0.71% , per annum, and receiving floating rates on a total notional amount of $100 million . The swaps are settled on a monthly basis, beginning in August 2011 and ending in August 2014.

Legacy accounts for these interest rate swaps pursuant to ASC 815 which establishes accounting and reporting standards requiring that derivative instruments be recorded at fair market value and included in the balance sheet as assets or liabilities.

Legacy does not specifically designate these derivative transactions as cash flow hedges, even though they reduce its exposure to changes in interest rates. Therefore, the mark-to-market of these instruments is recorded in current earnings as a component of interest expense. The total impact on interest expense from the mark-to-market and settlements was as follows:

(7)	Asset Retirement Obligation

ASC 410-20 requires that an asset retirement obligation (“ARO”) associated with the retirement of a tangible long-lived asset be recognized as a liability in the period in which it is incurred and becomes determinable. Under this method, when liabilities for dismantlement and abandonment costs, excluding salvage values, are initially recorded, the carrying amount of the related oil and natural gas properties is increased. The fair value of the ARO asset and liability is measured using expected future cash outflows discounted at Legacy’s credit-adjusted risk-free interest rate. Accretion of the liability is recognized each period using the interest method of allocation, and the capitalized cost is depleted over the useful life of the related asset.

The following table reflects the changes in the ARO during the three months ended March 31, 2012 and year ended December 31, 2011 :

For the three months ended March 31, 2011 , 81,203 restricted units were excluded from the calculation of diluted earnings per unit due to their anti-dilutive effect.


(9)	Unit-Based Compensation

Long-Term Incentive Plan

On March 15, 2006, a Long-Term Incentive Plan (“LTIP”) for Legacy was implemented for its employees, consultants and directors, its affiliates and its general partner. The awards under the LTIP may include unit grants, restricted units, phantom units, unit options and unit appreciation rights. The LTIP permits the grant of awards covering an aggregate of 2,000,000 units. As of March 31, 2012 , grants of awards net of forfeitures covering 1,644,477 units had been made, comprised of 266,014 unit option awards, 757,178 unit appreciation rights awards ("UARs"), 210,004 restricted unit awards, 337,663 phantom unit awards and 73,618 unit awards. The LTIP is administered by the compensation committee (the “Compensation Committee”) of the board of directors of Legacy’s general partner.

ASC 718 requires companies to measure the cost of employee services in exchange for an award of equity instruments based on a grant-date fair value of the award (with limited exceptions), and that cost must generally be recognized over the vesting period of the award. However, ASC 718 stipulates that “if an entity that nominally has the choice of settling awards by issuing stock predominately settles in cash, or if the entity usually settles in cash whenever an employee asks for cash settlement, the entity is settling a substantive liability rather than repurchasing an equity instrument.” Due to Legacy's historical practice of settling unit options, UARs and phantom unit awards in cash, Legacy accounts for unit options, UARs, and phantom unit awards by utilizing the liability method as described in ASC 718. The liability method requires companies to measure the cost of the employee services in exchange for a cash award based on the fair value of the underlying security at the end of each reporting period. Compensation cost is recognized based on the change in the liability between periods.

Unit Appreciation Rights and Unit Options

Page 21

A unit appreciation right is a notional unit that entitles the holder, upon vesting, to receive cash valued at the difference between the closing price of units on the exercise date and the exercise price, as determined on the date of grant. Because these awards are settled in cash, Legacy is accounting for the UARs by utilizing the liability method.

During the year ended December 31, 2011 , Legacy issued 68,000 UARs to employees which vest ratably over a three-year period and 50,034 UARs to employees which vest at the end of a three-year period. During the three -month period ended March 31, 2012 , Legacy issued 17,000 UARs to employees which vest ratably over a three-year period. All UARs granted in 2011 and 2012 expire seven years from the grant date and are exercisable when they vest.

For the three -month periods ended March 31, 2012 and 2011 , Legacy recorded $0.4 million and $0.9 million , respectively, of compensation expense due to the change in liability from December 31, 2011 and 2010 , respectively, based on its use of the Black-Scholes model to estimate the March 31, 2012 and 2011 fair value of these UARs and unit options (see Note 5). As of March 31, 2012 , there was a total of approximately $1.4 million of unrecognized compensation costs related to the unexercised and non-vested portion of these UARs. At March 31, 2012 , this cost was expected to be recognized over a weighted-average period of approximately 1.8 years. Compensation expense is based upon the fair value as of March 31, 2012 and is recognized as a percentage of the service period satisfied. Since Legacy's trading history does not yet match the term of the outstanding UAR and unit option awards, it has used an estimated volatility factor of approximately 49% based upon the historical trends of a representative group of publicly-traded companies in the energy industry and employed the Black-Scholes model to estimate the March 31, 2012 fair value to be realized as compensation cost based on the percentage of service period satisfied. Based on historical data, Legacy has assumed an estimated forfeiture rate of 3.0% . As required by ASC 718, Legacy will adjust the estimated forfeiture rate based upon actual experience. Legacy has assumed an annual distribution rate of $2.20 per unit.

A summary of UAR and unit option activity for the three months ended March 31, 2012 is as follows:



	Units		Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Term	Aggregate Intrinsic Value
Outstanding at January 1, 2012	620,031		$	22.36
Granted	17,000		28.79
Exercised	(51,833	)	21.09
Forfeited	(13,666	)	22.32
Outstanding at March 31, 2012	571,532		$	22.67	4.20	$	3,632,238

UARs and unit options exercisable at March 31, 2012	183,932		$	21.75	1.60	$	1,318,518

The following table summarizes the status of Legacy’s non-vested UARs since January 1, 2012:



	Non-Vested UARs
	Number of Units		Weighted-Average Exercise Price
Non-vested at January 1, 2012	387,766		$	22.80
Granted	17,000		28.79
Vested - Unexercised	(3,500	)	23.73
Vested - Exercised	(500	)	10.20
Forfeited	(13,166	)	22.03
Non-vested at March 31, 2012	387,600		$	23.10

Legacy has used a weighted-average risk-free interest rate of 0.9% in its Black-Scholes calculation of fair value, which approximates the U.S. Treasury interest rates at March 31, 2012 whose terms are consistent with the expected life of the UARs and unit options. Expected life represents the period of time that UARs and unit options are expected to be outstanding and is based on Legacy’s best estimate. The following table represents the weighted-average assumptions used for the Black-Scholes option-pricing model.

Phantom Units

As described below, Legacy has also issued phantom units under the LTIP. A phantom unit is a notional unit that entitles the holder, upon vesting, to receive cash valued at the closing price of units on the vesting date, or, at the discretion of the Compensation Committee, the same number of Partnership units. Because Legacy’s current intent is to settle these awards in cash, Legacy is accounting for the phantom units by utilizing the liability method.

On September 21, 2009, the board of directors of Legacy’s general partner, upon the recommendation of the Compensation Committee, implemented the current equity-based incentive compensation policy applicable to the five executive officers of Legacy. In addition to cash bonus awards, under the compensation plan, the executives are eligible for both subjective and objective grants of phantom units. The subjective, or service-based, grants may be awarded up to a maximum percentage of annual salary ranging from 40% to 100% as determined by the Compensation Committee. Once granted, these phantom units vest ratably over a three-year period. The objective, or performance-based, grants may be awarded up to a maximum percentage of annual salary ranging from 60% to 150% , as determined by the Compensation Committee. However, the amount to vest each year for the three-year vesting period will be determined on each vesting date based on a three-step process, with the first two steps each comprising 50% of the total vesting amount while the third step is the sum of the first two steps. The first step in the process will be a function of Total Unitholder Return (“TUR”) for the Partnership and the ordinal rank of the Legacy TUR among a peer group of upstream master limited partnerships, as determined by the Compensation Committee at the beginning of each year. The percentage of the 50% performance-based award to vest under this step is determined within a matrix which ranges from 0% to 100% and will increase from 0% to 100% as each of the Legacy TUR and the ordinal rank of the Legacy TUR among the peer group increase. The applicable Legacy TUR range is from less than 8% (where 0% to 25% of the amount will vest, depending upon the Legacy TUR ranking among its peer group) to more than 20% (where 50% to 100% of the amount will vest, depending upon the Legacy TUR ranking among its peer group). In the second step, the Legacy TUR will be compared to the TUR of a group of master limited partnerships included in the Alerian MLP Index. The percentage of the 50% of the performance-based award to vest under this step is determined within a matrix which ranges from 0% to 100% and will increase from 0% to 100% as the Legacy TUR and the percentile rank of the Legacy TUR among the Adjusted Alerian MLP Index increases. The applicable Legacy TUR range is from less than 8% (where 0% to 30% of the amount will vest, depending upon the Legacy TUR percentile ranking among the Adjusted Alerian MLP Index) to more than 20% (where 50% to 100% of the amount will vest, depending upon the Legacy TUR percentile ranking among the Adjusted Alerian MLP Index). The third step is the addition of the above two steps to determine the total performance-based awards to vest. Performance based phantom units subject to vesting which do not vest in a given year will be forfeited. With respect to both the subjective and objective units awarded under this compensation policy, DERs will accumulate and accrue based on the total number of actual amounts vested and will be payable at the date of vesting.

On February 18, 2011 , the Compensation Committee approved the award of 32,806 subjective, or service-based, phantom units and 53,487 objective, or performance based, phantom units to Legacy’s five executive officers. On February 1, 2012 and February 2, 2012 , the Compensation Committee approved the award of 30,828 subjective, or service-based, phantom units and 57,189 objective, or performance based, phantom units to Legacy’s five executive officers. Upon his resignation effective March 16, 2012, Legacy's former President and Chief Financial Officer forfeited all of his unvested phantom unit awards.

Compensation expense related to the phantom units and associated DERs was $0.8 million and $0.8 million for the three months ended March 31, 2012 and 2011 , respectively.

Restricted Units

During the year ended December 31, 2011 , Legacy issued an aggregate of 51,365 restricted units to non-executive employees. The restricted units awarded vest ratably over a three-year period, beginning on the date of grant. During the three -month period ended March 31, 2012 , Legacy issued an aggregate of 13,000 restricted units to non-executive employees. The

Page 23

restricted units awarded vest ratably over a three-year period, beginning on the date of grant. Compensation expense related to restricted units was $0.3 million and $0.2 million for the three months ended March 31, 2012 and 2011 , respectively. As of March 31, 2012 , there was a total of $2.0 million of unrecognized compensation expense related to the unvested portion of these restricted units. At March 31, 2012 , this cost was expected to be recognized over a weighted-average period of 2.2 years. Pursuant to the provisions of ASC 718, Legacy’s issued units, as reflected in the accompanying consolidated balance sheet at March 31, 2012 , do not include 115,791 units related to unvested restricted unit awards.

Board Units

On May 11, 2011, Legacy granted and issued 1,630 units to each of its five non-employee directors as part of their annual compensation for serving on the board of directors of Legacy's general partner. The value of each unit was $30.24 at the time of issuance. On August 26, 2011, Legacy granted and issued 1,885 units to each of its five non-employee directors as part of their annual compensation for serving on the board of directors of Legacy's general partner. The value of each unit was $26.94 at the time of issuance.

(10) Subsidiary Guarantors

Legacy and Legacy Reserves Finance Corporation filed an automatic registration statement on Form S-3 on May 23, 2011. Securities that may be offered and sold include debt securities which may be guaranteed by Legacy's subsidiaries and are to be offered on a delayed or continuous basis pursuant to Rule 415 under the Securities Act of 1933. Legacy, as the parent company, has no independent assets or operations. Legacy contemplates that if it offers guaranteed debt securities pursuant to the registration statement, all guarantees will be full and unconditional and joint and several, and any subsidiaries of Legacy other than the subsidiary guarantors will be minor. In addition, there are no restrictions on the ability of Legacy to obtain funds from its subsidiaries by dividend or loan.

(11) Equity Distribution Agreement

Units Issued

Legacy currently has an Equity Distribution Agreement with Knight Capital Americas, L.P. ("KCA") under which Legacy may offer and sell units from time to time through KCA, as Legacy's sales agent. During the year ended December 31, 2011 , Legacy received proceeds from 87,364 units issued pursuant to this agreement of approximately $2.4 million gross and $2.3 million net of commissions, which proceeds were used for general partnership purposes. No sales were made during the quarter ended March 31, 2012 .

(12) Subsequent Events

On April 19, 2012, Legacy’s board of directors approved a distribution of $0.555 per unit payable on May 11, 2012 to unitholders of record on April 30, 2012, representing an increase of $0.005 per unit over the last quarterly distribution.

Overview

We were formed in October 2005. Upon completion of our private equity offering on March 15, 2006, we acquired oil and natural gas properties and business operations from our founding investors and three charitable foundations.

Because of our rapid growth through acquisitions and development of properties, historical results of operations and period-to-period comparisons of these results and certain financial data may not be meaningful or indicative of future results.

Acquisitions have been financed with a combination of proceeds from bank borrowings, issuances of units and cash flow from operations. Post-acquisition activities are focused on evaluating and developing the acquired properties and evaluating potential add-on acquisitions.

Our revenues, cash flow from operations and future growth depend substantially on factors beyond our control, such as

Page 25

economic, political and regulatory developments and competition from other sources of energy. Oil and natural gas prices historically have been volatile and may fluctuate widely in the future.

Sustained periods of low prices for oil or natural gas could materially and adversely affect our financial position, our results of operations, the quantities of oil and natural gas reserves that we can economically produce, our access to capital and the amount of our cash distributions.

We face the challenge of natural production declines. As initial reservoir pressures are depleted, oil and natural gas production from a given well or formation decreases. We attempt to overcome this natural decline by acquiring more reserves than we produce, drilling to find additional reserves, utilizing multiple types of recovery techniques such as secondary (waterflood) and tertiary (CO2 and nitrogen) recovery methods to re-pressure the reservoir and recover additional oil, re-completing or adding pay in existing wellbores and improving artificial lift. Our future growth will depend on our ability to continue to add reserves in excess of production. We will maintain our focus on adding reserves through acquisitions and exploitation projects. Our ability to add reserves through acquisitions and exploitation projects is dependent upon many factors including our ability to raise capital, obtain regulatory approvals and contract drilling rigs and personnel.

Our revenues are highly sensitive to changes in oil and natural gas prices and to levels of production. As set forth under “Investing Activities” below, we have entered into oil and natural gas derivatives designed to mitigate the effects of price fluctuations covering a significant portion of our expected production, which allows us to mitigate, but not eliminate, oil and natural gas price risk. We continuously conduct financial sensitivity analyses to assess the effect of changes in pricing and production. These analyses allow us to determine how changes in oil and natural gas prices will affect our ability to execute our capital investment programs and to meet future financial obligations. Further, the financial analyses allow us to monitor any impact such changes in oil and natural gas prices may have on the value of our proved reserves and their impact, if any, on any redetermination of our borrowing base under our revolving credit facility.

Legacy does not specifically designate derivative instruments as cash flow hedges; therefore, the mark-to-market adjustment reflecting the unrealized gain or loss associated with these instruments is recorded in current earnings.

Production and Operating Costs Reporting

We strive to increase our production levels to maximize our revenue and cash available for distribution. Additionally, we continuously monitor our operations to ensure that we are incurring operating costs at the optimal level. Accordingly, we continuously monitor our production and operating costs per well to determine if any wells or properties should be shut-in or re-completed.

Such costs include, but are not limited to, the cost of electricity to lift produced fluids, chemicals to treat wells, field personnel to monitor the wells, well repair expenses to restore production, well workover expenses intended to increase production, and ad valorem taxes. We incur and separately report severance taxes paid to the states in which our properties are located. These taxes are reported as production taxes and are a percentage of oil and natural gas revenue. Ad valorem taxes are a percentage of property valuation and are reported with production costs. Gathering and transportation costs are generally borne by the purchasers of our oil and natural gas as the price paid for our products reflects these costs. We do not consider royalties paid to mineral owners an expense as we deduct hydrocarbon volumes owned by mineral owners from the reported hydrocarbon sales volumes.

Results of Operations

Three-Month Period Ended March 31, 2012 Compared to Three-Month Period Ended March 31, 2011

Legacy’s revenues from the sale of oil were $76.1 million and $59.3 million for the three-month periods ended March 31, 2012 and 2011 , respectively. Legacy’s revenues from the sale of NGLs were $3.7 million and $4.3 million for the three-month periods ended March 31, 2012 and 2011 , respectively. Legacy’s revenues from the sale of natural gas were $12.8 million and $9.3 million for the three-month periods ended March 31, 2012 and 2011 , respectively. The $16.9 million increase in oil revenues reflects the increase in average realized price of $8.95 per Bbl ( 10% ) and an increase in oil production of 112 MBbls ( 17% ). This increase in production is due to Legacy’s purchase of additional oil and natural gas properties during 2011 as well as Legacy's ongoing development activities that are focused in the Permian Basin, primarily the Wolfberry play. The $0.5 million decrease in NGL sales reflects a decrease in the average realized price of $0.21 per gallon ( 16% ) partially offset by an increase in NGL production of approximately 173 MGals ( 5% ) due primarily to Legacy's purchase of additional oil and natural gas properties during 2011 and development activities. The $3.5 million increase in natural gas revenues reflects an increase in natural gas production partially offset by a decrease in average realized prices. Our natural gas production increased approximately 1,057 MMcf ( 66% ) due primarily to Legacy’s purchase of additional oil and natural gas properties as well as Legacy's ongoing development activities that are primarily focused in the Permian Basin, specifically the Wolfberry play, in which we produce primarily oil but also a significant amount of NGL-rich, casinghead natural gas. Legacy's average realized natural gas price decreased by $0.97 per Mcf ( 17% ), which reflects declining NYMEX natural gas prices. We primarily report and account for our Permian Basin natural gas volumes inclusive of the NGL content contained with those natural gas volumes. Given the price disparity between an equivalent amount of NGLs compared to natural gas, our realized natural gas prices in the Permian Basin and for Legacy as a whole are substantially higher than NYMEX Henry Hub natural gas prices due to the NGL content.

For the three-month period ended March 31, 2012 , Legacy recorded $23.1 million of net losses on oil and natural gas derivatives comprised of realized losses of $2.1 million from net cash settlements of oil and natural gas derivative contracts and a net unrealized losses of $21.0 million . Unrealized gains and losses represent a current period mark-to-market adjustment for commodity derivatives that will be settled in future periods. Legacy had unrealized net losses of $23.3 million from oil derivatives because oil futures prices increased during the three-month period ended March 31, 2012 . Since oil futures prices at March 31, 2012 exceeded the average contract prices of Legacy’s outstanding oil derivatives contracts by a greater margin than at December 31, 2011 , the net liability attributable to unrealized net losses from Legacy’s outstanding oil derivatives increased. Legacy had unrealized net gains from natural gas derivatives of $2.2 million because the NYMEX natural gas futures prices decreased during the three-month period ended March 31, 2012 . Due to this decrease in natural gas prices during the quarter, the positive differential between Legacy’s fixed price natural gas derivatives and NYMEX prices increased. Accordingly, the net asset attributable to unrealized net gains from Legacy’s outstanding natural gas derivatives increased. For the three-month period ended March 31, 2011 , Legacy recorded $75.5 million of net losses on oil and natural gas derivatives, comprised of realized gains of $1.7 million from net cash settlements of oil and natural gas derivative contracts and a net unrealized losses of $77.1 million .

Legacy’s oil and natural gas production expenses, excluding ad valorem taxes, increased to $23.0 million ( $17.49 per Boe) for the three-month period ended March 31, 2012 from $21.5 million ( $21.03 per Boe) for the three-month period ended March 31, 2011 . Production expenses increased primarily due to the purchases of oil and natural gas properties, expenses associated with Legacy's development activity, a $0.4 million increase in workover expenses and industry-wide cost increases due to higher oil prices. Additionally, Legacy's production expense per Boe decreased from $21.03 per Boe for the three month period ended March 31, 2011 to $17.49 for the three month period ended March 31, 2012 . This decrease on a per Boe basis was primarily caused by two factors. Initially, production was 29% higher for the three month period ended March 31, 2012 compared to the same period in 2011 . The 2012 production amounts included production from acquisitions of natural gas properties, which typically have lower operating costs per Boe than oil properties, acquired subsequent to March 31, 2011 . In addition, production expenses per Boe were adversely affected during the three month period ended March 31, 2011 due to lower sales volumes driven by extremely cold weather in the Permian Basin. Legacy’s ad valorem tax expense decreased to $1.9 million ( $1.45 per Boe) for the three-month period ended March 31, 2012 , from $2.3 million ( $2.21 per Boe) for the three-month period ended March 31, 2011 .

Legacy’s production and other taxes were $5.2 million and $4.4 million for the three-month periods ended March 31, 2012 and 2011 , respectively. Production and other taxes increased primarily because of higher realized commodity prices and production volumes, as production and other taxes as a percentage of revenue remained largely unchanged.

Legacy’s general and administrative expenses were $6.5 million and $6.4 million for the three-month periods ended March 31, 2012 and 2011 , respectively. General and administrative expenses increased $0.1 million as increases in salaries and

Page 28

benefits related to the hiring of additional personnel was primarily offset by a decrease in unit-based compensation of $0.4 million.

Legacy’s depletion, depreciation, amortization and accretion expense, or DD&A, was $22.8 million and $19.6 million for the three-month periods ended March 31, 2012 and 2011 , respectively. DD&A increased primarily because of increased production from our development activity and recent acquisitions, as well as proportionate increases in cost basis. These increases were partially offset by increased reserve volumes related to our development activities, acquisitions and higher average commodity prices.

Impairment expense was $1.3 million and $1.0 million for the three-month periods ended March 31, 2012 and 2011 , respectively. In the three-month period ended March 31, 2012 , Legacy recognized impairment expense on 11 separate producing fields primarily related to lower natural gas prices at March 31, 2012 compared to December 31, 2011 , which reduced the future expected cash flows. Impairment expense for the period ended March 31, 2011 , was related to reserve valuation adjustments on properties acquired in late 2010.

Legacy recorded interest expense of $4.3 million and $3.4 million for the three-month periods ended March 31, 2012 and 2011 , respectively. Interest expense increased approximately $1.0 million due primarily to a reduction in the mark-to-market of our interest rate swap derivatives to a $0.3 million reduction in interest expense for the three-month period ended March 31, 2012 , compared to a $1.7 million reduction in interest expense for the three-month period ended March 31, 2011 .

Non-GAAP Financial Measures

For the three months ended March 31, 2012 and 2011 , respectively, Adjusted EBITDA (as defined below) increased 30% to $55.2 million from $42.3 million primarily due to increased revenues from our oil, NGL and natural gas sales in the three months ended March 31, 2012 compared to the three months ended March 31, 2011 , partially offset by higher production and other expenses. These increased revenues were also partially offset by decreased realized commodity derivative settlements of approximately $3.7 million from cash proceeds of $1.7 million to cash payments of $2.1 million for the three months ended March 31, 2011 and 2012 , respectively. For the three months ended March 31, 2012 and 2011 , respectively, Distributable Cash Flow increased 55% to $36.4 million from $23.6 million , primarily due to the increased Adjusted EBITDA.

Legacy's management uses Adjusted EBITDA and Distributable Cash Flow as tools to provide additional information and metrics relative to the performance of Legacy’s business, such as the cash distributions Legacy expects to pay to its unitholders. Legacy’s management believes that both Adjusted EBITDA and Distributable Cash Flow are useful to investors because these measures are used by many companies in the industry as measures of operating and financial performance and are commonly employed by financial analysts and others to evaluate the operating and financial performance of the Partnership from period to period and to compare it with the performance of other publicly traded partnerships within the industry. Adjusted EBITDA and Distributable Cash Flow may not be comparable to a similarly titled measure of other publicly traded limited partnerships or limited liability companies because all companies may not calculate Adjusted EBITDA in the same manner.

The following presents a reconciliation of “Adjusted EBITDA” and “Distributable Cash Flow,” both of which are non-GAAP measures, to their nearest comparable GAAP measure. “Adjusted EBITDA” and “Distributable Cash Flow” should not be considered as alternatives to GAAP measures, such as net income, operating income, cash flow from operating activities, or any other GAAP measure of financial performance.

Adjusted EBITDA is defined in Legacy’s revolving credit facility as net income (loss) plus:


•	Interest expense;


•	Income taxes;


•	Depletion, depreciation, amortization and accretion;


•	Impairment of long-lived assets;


•	(Gain) loss on sale of partnership investment;


•	(Gain) loss on disposal of assets (excluding settlements of asset retirement obligations);


•	Equity in (income) loss of partnership.


•	Unit-based compensation expense related to LTIP unit awards accounted for under the equity or liability methods; and


•	Unrealized (gain) loss on oil and natural gas derivatives.

Distributable Cash Flow is defined as Adjusted EBITDA less:


•	Cash interest expense;


•	Cash income taxes;

Page 29


•	Cash settlements of LTIP unit awards; and


•	Development capital expenditures.

The following table presents a reconciliation of Legacy’s consolidated net income to Adjusted EBITDA and Distributable Cash Flow for the three months ended March 31, 2012 and 2011 , respectively.

Capital Resources and Liquidity

Legacy’s primary sources of capital and liquidity have been bank borrowings, cash flow from operations, the issuance of additional units or a combination thereof. To date, Legacy’s primary uses of capital have been for acquisitions, repayment of bank borrowings and development of oil and natural gas properties.

We continually monitor the capital resources available to us to meet our future financial obligations and planned capital expenditures. Our future success in maintaining and growing reserves and production will be highly dependent on capital resources available to us and our success in acquiring and developing additional reserves. If we were to make significant additional acquisitions for cash, we would need to borrow additional amounts under our credit facility, if available, or obtain additional debt or equity financing. Further, our revolving credit facility imposes specific restrictions on our ability to obtain additional debt financing. Please see “ – Financing Activities – Our Revolving Credit Facility.” Based upon current oil and natural gas price expectations and our extensive commodity derivatives positions for the year ending December 31, 2012 , we anticipate that our cash on hand, cash flow from operations and available borrowing capacity under our credit facility will provide us sufficient working capital to meet our currently planned capital expenditures and future cash distributions at levels to be determined based on cash available for distribution, any remaining borrowing capacity for cash distributions under our credit facility, requirements to repay debt, and any other factors the board of directors of our general partner may consider.

The amounts available for borrowing under our credit facility are subject to a borrowing base, which is currently set at $565.0 million . As of May 3, 2012 , we had $222.9 million available for borrowing under our revolving credit facility. Based on their commodity price expectations, our lenders redetermine the borrowing base semi-annually, with the next redetermination scheduled for October 2012. Please see “— Financing Activities — Our Revolving Credit Facility.”

Cash Flow from Operations

Legacy’s net cash provided by operating activities was $44.8 million and $34.4 million for the three -month periods ended March 31, 2012 and 2011 , respectively. The 2012 period was favorably impacted by higher commodity prices and

Page 30

production volumes, which were partially offset by higher expenses. In addition, the net cash amounts for 2012 and 2011 do not include cash settlements received/(paid) of $(2.1) million and $1.7 million , respectively, from our commodity derivative transactions.

Our cash flow from operations is subject to many variables, the most significant of which is the volatility of oil and natural gas prices. Oil and natural gas prices are determined primarily by prevailing market conditions, which are dependent on regional and worldwide economic activity, weather and other factors beyond our control. Our future cash flow from operations will depend on our ability to maintain and increase production through acquisitions and development projects, as well as the prices of oil and natural gas.

Investing Activities

Legacy’s cash capital expenditures were $20.1 million for the three -month period ended March 31, 2012 . The total includes $7.9 million for the acquisition of oil and natural gas properties in two individually immaterial acquisitions and $12.2 million of development projects. Legacy’s cash capital expenditures were $24.0 million for the three -month period ended March 31, 2011 . The total includes $12.1 million for the acquisition of oil and natural gas properties in six individually immaterial acquisitions and $11.9 million of development projects.

Our capital expenditure budget, which predominantly consists of drilling, re-completion and capital workover projects, is currently $62.0 million for the year ending December 31, 2012 , of which $12.2 million has been expended during the three -months ended March 31, 2012 . Our remaining borrowing capacity under our revolving credit facility is $222.9 million as of May 3, 2012 . The amount and timing of our capital expenditures is largely discretionary and within our control, with the exception of certain projects managed by other operators. We may defer a portion of our planned capital expenditures until later periods. Accordingly, we routinely monitor and adjust our capital expenditures in response to changes in oil and natural gas prices, drilling and acquisition costs, industry conditions and internally generated cash flow. Matters outside our control that could affect the timing of our capital expenditures include obtaining required permits and approvals in a timely manner. Based upon current oil and natural gas price expectations for the year ending December 31, 2012 , we anticipate that we will have sufficient sources of working capital, including our cash flow from operations and available borrowing capacity under our credit facility, to meet our cash obligations including our remaining planned capital expenditures of $49.8 million . Future cash distributions will be at levels to be determined based on cash available for distribution, any remaining borrowing capacity for cash distributions under our credit facility, requirements to repay debt and any other factors the board of directors of our general partner may consider. However, future cash flows are subject to a number of variables, including the level of oil and natural gas production and prices. There can be no assurance that operations and other capital resources will provide cash in sufficient amounts to maintain planned levels of capital expenditures.

We enter into oil and natural gas derivative transactions to reduce the impact of oil and natural gas price volatility on our operations. Currently, we use derivatives to offset price volatility on NYMEX oil and natural gas prices, which do not include the additional net discount that we typically experience in the Permian Basin. For the three -month period ended March 31, 2012 and 2011 we had unfavorable cash settlements of $(2.1) million and favorable cash settlements of $1.7 million , respectively, related to our commodity derivative settlements. At March 31, 2012 , we had in place oil and natural gas derivatives covering significant portions of our estimated 2012 through 2016 oil, NGL and natural gas production. As of May 3, 2012 , we have derivative contracts covering approximately 76% of our remaining expected oil, NGL and natural gas production for 2012 . As of May 3, 2012 , we also have derivative contracts covering approximately 41% of our currently expected oil and natural gas production for 2013 through December 2016.

By reducing the cash flow effects of price volatility from a significant portion of our oil and natural gas production, we have mitigated, but not eliminated, the potential effects of changing prices on our cash flow from operations for those periods. While mitigating negative effects of falling commodity prices, these derivative contracts also limit the benefits we would receive from increases in commodity prices. It is our policy to enter into derivative contracts only with counterparties that are major, creditworthy financial institutions deemed by management as competent and competitive market makers. In addition, these counterparties are current or former lenders under our revolving credit facility, which allows us to avoid margin calls. However, we cannot be assured that all of our counterparties will meet their obligations under our derivative contracts. Due to this uncertainty, we routinely monitor the creditworthiness of our counterparties.

The following tables summarize, for the periods indicated, our oil and natural gas derivatives currently in place as of May 3, 2012 , covering the period from April 1, 2012 through June 30, 2017. We use derivatives, including swaps, collars and 3-way collars, as our mechanism for offsetting the cash flow effects of changes in commodity prices whereby we pay the counterparty floating prices and receive fixed prices from the counterparty, which serves to reduce the effects on cash flow of the floating prices we are paid by purchasers of our oil and natural gas. These transactions are settled based upon the monthly

Page 31

average closing price of the front-month NYMEX WTI oil contract price of oil at Cushing, Oklahoma, and West Texas Waha, Rocky Mountain CIG and ANR-Oklahoma prices of natural gas on the average of the three final trading days of the month and settlement occurs on the fifth day of the production month.

(a)

On October 6, 2010, as part of an oil swap transaction entered into with a counterparty, we sold two call options to the counterparty that allow the counterparty to extend a swap transaction covering calendar year 2011 to either 2012, 2013 or both calendar years. The counterparty exercised the option covering calendar year 2012 on December 30, 2011 and must exercise or decline the option covering calendar year 2013 on December 31, 2012. As the option was exercised for calendar year 2012, we will pay the counterparty floating prices and receive a fixed price of $98.25 per Bbl on annual notional volumes of 183,000 Bbls (137,500 Bbls remaining as of April 1, 2012 ). For calendar year 2013, if exercised, we would pay the counterparty floating prices and receive a fixed price of $98.25 per Bbl on annual notional volumes of 182,500 Bbls in 2013. The premium paid by the counterparty to us for the two call options was in the form of an increase in the fixed price that we received pursuant to the 2011 swap of $98.25 per Bbl on 182,500 Bbls, or 500 Bbls per day, rather than the prevailing market price of approximately $87.00 per Bbl. These additional potential volumes related to the unexercised 2013 option are not reflected in the above table.

On June 24, 2008, we entered into a NYMEX West Texas Intermediate crude oil derivative collar contract that combines a long put option or “floor” with a short call option or “ceiling.” The following table summarizes the oil collar contract currently in place as of May 3, 2012 , covering the period from April 1, 2012 through December 31, 2012:

On January 12, 2011, we entered into a West Texas Waha natural gas derivative collar contract that combines a long put option or "floor" with a short call option or "ceiling." The following table summarizes the natural gas collar contract currently in place as of May 3, 2012 , covering the period from April 1, 2012 through December 31, 2012:

We have entered into multiple NYMEX West Texas Intermediate crude oil derivative three-way collar contracts. Each contract combines a long put, a short put and a short call. The use of the long put combined with the short put allows us to sell a call at a higher ceiling and limits our exposure to future settlement payments while also restricting our downside risk to the difference between the long put and the short put if the price of NYMEX West Texas Intermediate crude oil drops below the price of the short put. This allows us to settle for WTI market plus the spread between the short put and the long put in a case where the market price has fallen below the short put fixed price. In regards to our three-way collar contracts, if the market price has fallen below the short put fixed price, we would receive the market price plus $25 or $30 per barrel, depending on the contract. The following table summarizes the three-way oil collar contracts currently in place as of May 3, 2012 , covering the period from April 1, 2012 through June 30, 2017:

Financing Activities

Legacy’s net cash used in financing activities was $30.6 million for the three months ended March 31, 2012 , compared to net cash used of $13.6 million for the three months ended March 31, 2011 . During the three months ended March 31, 2012 , total net payments under our revolving credit facility were $4.0 million , comprised of borrowings of $76.0 million and repayments of $80.0 million . Additionally, Legacy had cash outflow during the three months ended March 31, 2012 in the amount of $26.4 million for distributions to unitholders. Cash used in financing activities during the three months ended March 31, 2011 , included $14.0 million in net borrowings under our revolving credit facility and $22.9 million for distributions to unitholders.

Our Revolving Credit Facility

Previous Credit Agreement

On March 27, 2009, we entered into a three-year, $600 million secured revolving credit facility (the “Previous Credit Agreement”) and retained BNP Paribas as administrative agent to replace our initial four-year, $300 million revolving credit facility with BNP Paribas as administrative agent. All borrowings outstanding under the Previous Credit Agreement were paid in full on March 10, 2011 with borrowings under the Current Credit Agreement.

Current Credit Agreement

On March 10, 2011, we entered into an amended and restated five-year, $1 billion secured revolving credit facility with BNP Paribas as administrative agent (the "Current Credit Agreement"). In conjunction with BNP Paribas' sale of its energy lending practice to Wells Fargo, Wells Fargo is now the administrative agent under the Current Credit Agreement effective April 20, 2012. Our obligations under the Current Credit Agreement are secured by mortgages on 80% of our oil and natural gas properties as well as a pledge of all of our ownership interests in our operating subsidiaries. Borrowings under the Current Credit Agreement mature on March 10, 2016. The amount available for borrowing at any one time is limited to the borrowing base, originally set at $500 million, currently set at $565 million , with a $2 million sub-limit for letters of credit. The borrowing base is subject to semi-annual redeterminations on or about April 1 and October 1 of each year. Additionally, either Legacy or the lenders may, once during each calendar year, elect to redetermine the borrowing base between scheduled redeterminations. We also have the right, once during each calendar year, to request the redetermination of the borrowing base upon the proposed acquisition of certain oil and natural gas properties where the purchase price is greater than 10% of the borrowing base. Any increase in the borrowing base requires the consent of all the lenders and any decrease in or maintenance of the borrowing base must be approved by the lenders holding at least 66.67% of the outstanding aggregate principal amounts of the loans or participation interests in letters of credit issued under the credit facility. If the required lenders do not agree on an increase or decrease, then the borrowing base will be the highest borrowing base acceptable to the lenders holding 66.67% of the outstanding aggregate principal amounts of the loans or participation interests in letters of credit issued under the credit facility, so long as it does not increase the borrowing base then in effect. Outstanding borrowings in excess of the borrowing base must be prepaid, and, if mortgaged properties represent less than 80% of total value of oil and gas properties evaluated in the most recent reserve report, we must pledge other oil and natural gas properties as additional collateral. Legacy may at any time issue up to $500 million in aggregate principal amount of senior notes or new debt whose proceeds are used to refinance such senior notes, subject to specified conditions in the Current Credit Agreement, which include that upon the issuance of such senior notes or new debt, the borrowing base shall be reduced by an amount equal to (i) in the case of senior notes, 25% of the stated principal amount of the senior notes and (ii) in the case of new debt, 25% of the portion of the new debt that exceeds the principal amount of the senior notes. Also, notwithstanding that a lender (or its affiliate) is no longer a party to the Current Credit Agreement, any lender (or its affiliate) which has entered into any hedging arrangement with us while a party to the Current Credit Agreement will continue to have our obligations under such hedging arrangement secured on a ratable and pari

Page 33

passu basis by the collateral securing our obligations under the Current Credit Agreement, the related loan documents and our hedging arrangements.

We may elect that borrowings be comprised entirely of alternate base rate (“ABR”) loans or Eurodollar loans. Interest on the loans is determined as follows:


•	with respect to ABR loans, the alternate base rate equals the highest of the prime rate, the Federal funds effective rate plus 0.50%, or the one-month London interbank rate (“LIBOR”) plus 1.00%, plus an applicable margin ranging from and including 0.75% and 1.75% per annum, determined by the percentage of the borrowing base then in effect that is drawn, or


•	with respect to any Eurodollar loans, one-, two-, three- or six-month LIBOR plus an applicable margin ranging from and including 1.75% and 2.75% per annum, determined by the percentage of the borrowing base then in effect that is drawn.

We pay a commitment fee equal to 0.50% on the average daily amount of the unused amount of the commitments under the Current Credit Agreement, payable quarterly.

Interest is generally payable quarterly for ABR loans and on the last day of the applicable interest period for any Eurodollar loans.

Our Current Credit Agreement also contains various covenants that limit our ability to:


•	incur indebtedness;


•	enter into certain leases;


•	grant certain liens;


•	enter into certain derivatives;


•	make certain loans, acquisitions, capital expenditures and investments;


•	make distributions other than from available cash;


•	merge, consolidate or allow any material change in the character of our business; or


•	engage in certain asset dispositions, including a sale of all or substantially all of our assets.

Our Current Credit Agreement also contains covenants that, among other things, require us to maintain specified ratios or conditions as follows:


•	total debt as of the last day of the most recent quarter to EBITDA (as defined in the Current Credit Agreement) in total over the last four quarters of not more than 4.0 to 1.0; and


•	consolidated current assets, as of the last day of the most recent quarter and including the unused amount of the total commitments, to consolidated current liabilities as of the last day of the most recent quarter of not less than 1.0 to 1.0, excluding non-cash assets and liabilities under ASC 815, which includes the current portion of oil, natural gas derivatives and interest rate swaps.

If an event of default exists under our Current Credit Agreement, the lenders will be able to accelerate the maturity of the credit agreement and exercise other rights and remedies. Each of the following would be an event of default:


•	failure to pay any principal when due or any reimbursement amount, interest, fees or other amount within certain grace periods;


•	a representation or warranty is proven to be incorrect when made;


•	failure to perform or otherwise comply with the covenants or conditions contained in the credit agreement or other loan documents, subject, in certain instances, to certain grace periods;

Page 34


•	default by us on the payment of any other indebtedness in excess of $2.0 million, or any event occurs that permits or causes the acceleration of the indebtedness;


•	bankruptcy or insolvency events involving us or any of our subsidiaries;


•	the loan documents cease to be in full force and effect;


•	our failing to create a valid lien, except in limited circumstances;

•

a change of control, which will occur upon (i) the acquisition by any person or group of persons of beneficial ownership of more than 35% of the aggregate ordinary voting power of our equity securities, (ii) the first day on which a majority of the members of the board of directors of our general partner are not continuing directors (which is generally defined to mean members of our board of directors as of March 10, 2011 and persons who are nominated for election or elected to our general partner’s board of directors with the approval of a majority of the continuing directors who were members of such board of directors at the time of such nomination or election), (iii) the direct or indirect sale, transfer or other disposition in one or a series of related transactions of all or substantially all of the properties or assets (including equity interests of subsidiaries) of us and our subsidiaries to any person, (iv) the adoption of a plan related to our liquidation or dissolution or (v) Legacy Reserves GP, LLC ceasing to be our sole general partner;


•	the entry of, and failure to pay, one or more adverse judgments in excess of $2.0 million or one or more non-monetary judgments that could reasonably be expected to have a material adverse effect and for which enforcement proceedings are brought or that are not stayed pending appeal; and


•	specified ERISA events relating to our employee benefit plans that could reasonably be expected to result in liabilities in excess of $2.0 million in any year.

As of March 31, 2012 , Legacy was in compliance with all financial and other covenants of the revolving credit facility.

Legacy periodically enters into interest rate swap transactions to mitigate the volatility of interest rates. As of March 31, 2012 , Legacy had interest rate swaps on notional amounts of $364 million with a weighted-average fixed rate of 2.17% . These swaps mature between April 2013 and November 2015.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations is based upon the condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. Certain accounting policies involve judgments and uncertainties to such an extent that there is a reasonable likelihood that materially different amounts could have been reported under different conditions, or if different assumptions had been used. Estimates and assumptions are evaluated on a regular basis. Legacy based its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates and assumptions used in preparation of the financial statements. Changes in these estimates and assumptions could materially affect our financial position, results of operations or cash flows. Management considers an accounting estimate to be critical if:


•	it requires assumptions to be made that were uncertain at the time the estimate was made, and


•	changes in the estimate or different estimates that could have been selected could have a material impact on our consolidated results of operations or financial condition.

Page 35

Please read Note 1 of the Notes to the Condensed Consolidated Financial Statements here and in our Annual Report on Form 10-K for the period ended December 31, 2011 for a detailed discussion of all significant accounting policies that we employ and related estimates made by management.

Nature of Critical Estimate Item: Oil and Natural Gas Reserves — Our estimate of proved reserves is based on the quantities of oil and natural gas which geological and engineering data demonstrate, with reasonable certainty, to be recoverable in future years from known reservoirs under existing economic and operating conditions. LaRoche Petroleum Consultants, Ltd., annually prepares a reserve and economic evaluation of all our properties in accordance with SEC guidelines on a lease, unit or well-by-well basis, depending on the availability of well-level production data. The accuracy of our reserve estimates is a function of many factors including the following: the quality and quantity of available data, the interpretation of that data, the accuracy of various mandated economic assumptions, and the judgments of the individuals preparing the estimates. For example, we must estimate the amount and timing of future operating costs, severance taxes, development costs, and workover costs, all of which may in fact vary considerably from actual results. In addition, as prices and cost levels change from ye
