PART I Items 1 and 2. Business and Properties General Berry Petroleum Company, ("Berry" or "Company"), is an independent energy company engaged in the production, development, acquisition, exploitation and exploration of crude oil and natural gas. While the Company was incorporated in Delaware in 1985 and has been a publicly traded company since 1987, it can trace its roots in California oil production back to 1909. Currently, Berry's principal reserves and producing properties are located in Kern, Los Angeles and Ventura Counties in California. Information contained in this report on Form 10-K reflects the business of the Company during the year ended December 31, 2001. In March 2002, primarily in an effort to improve its competitive position in attracting and retaining talented personnel, the Company relocated its corporate headquarters to Bakersfield, California from its properties in the South Midway-Sunset field near Taft. Management believes that these new facilities are adequate for its current operations and anticipated growth. The Company's mission is to increase shareholder returns, primarily through maximizing the value and cash flow of the Company's assets. To achieve this, Berry's corporate strategy is to be a low-cost producer and to grow the Company's asset base strategically. To increase production and proved reserves, the Company will compete to acquire oil and gas properties with primarily proved reserves with exploitation potential and will focus on the further development of its existing properties by application of enhanced oil recovery (EOR) methods, developmental drilling, well completions and remedial work. In conjunction with the goals of being a low-cost heavy oil producer and the exploitation and development of its large heavy crude oil base, the Company owns three cogeneration facilities which are intended to provide an efficient and secure long-term supply of steam which is necessary for the economic production of heavy oil. Berry views these assets as a critical part of its long-term success. Berry believes that its primary strengths are its ability to maintain a low-cost operation, its flexibility in acquiring attractive producing properties which have significant exploitation and enhancement potential, its strong financial position and its experienced management team. While the Company continues to seek investment opportunities in California, the Company intends to pursue opportunities in other basins which would establish another core area and provide for additional growth opportunities and diversification of the Company's predominantly heavy oil resource base. The Company has over $100 million of unused borrowing capacity to finance acquisitions and will consider, if appropriate, the issuance of capital stock to finance future purchases. Proved Reserves As of December 31, 2001, the Company's estimated proved reserves were 103 million barrels of oil equivalent, (BOE), of which 99% are heavy crude oil, i.e., oil with an API gravity of less than 20 degrees. A significant portion of these proved reserves is owned in fee. Substantially all of the Company's reserves as of December 31, 2001 were located in California, with 74%, 20% and 4% of total proved reserves in Kern, Los Angeles and Ventura Counties, respectively. The Company's reserves have a long life, in excess of 20 years, which is primarily a result of the Company's strong position in heavy crude oil (the Company's properties in the Midway- Sunset and the Placerita fields average 13 degree API gravity and the Montalvo field averages 16 degree API gravity). Production in 2001 was 5 million BOE, down 9% from 2000 production of 5.5 million BOE. For the five years 1997 through 2001, the Company's average annual reserve replacement rate was 102% and the finding and development cost was $3.69 per BOE. Operations Berry operates all of its principal oil producing properties. The Midway-Sunset and Placerita fields contain predominantly heavy crude oil which requires heat, supplied in the form of steam, injected into the oil producing formations to reduce the oil viscosity which improves the mobility of the oil flowing to the well-bore for production. Berry utilizes cyclic steam recovery methods in the Midway-Sunset field, steam-drive in the Placerita field and primary recovery methods at its Montalvo field. Berry is able to produce its heavy oil at its Montalvo field without steam since the majority of the producing reservoir is at a depth in excess of 11,000 feet and thus the reservoir temperature is high enough to produce the oil without the assistance of additional heat from steam. Field operations include the initial recovery of the crude oil and its transport through treating facilities into storage tanks. After the treating process is completed, which 3

includes removal of water and solids by mechanical, thermal and chemical processes, the crude oil is metered through Lease Automatic Custody Transfer (LACT) units and either transferred into crude oil pipelines owned by other companies or, in the case of the Placerita field, transported via trucks. The point-of- sale is usually the LACT unit or truck loading facility. Revenues The percentage of revenues by source for the prior three years is as follows: 2001 2000 1999 Sales of oil and gas 72% 69% 66% Sales of electricity 26% 31% 33% Other 2% - 1% Oil Marketing The global and California crude oil markets have remained very volatile due to the impacts of the September 11, 2001 (9/11) terrorist attacks on the U.S. and as OPEC attempts to manage crude oil prices in the midst of fluctuating inventory levels and petroleum product demand weakness due to worldwide economic slowdowns. Oil prices remained strong in 2001 until the economic impacts of 9/11 caused the price to decline by $9/Bbl before rebounding a few dollars. The price for West Texas Intermediate (WTI), the U.S. benchmark crude oil, averaged $25.88 for 2001 compared to $30.26 in 2000 and $19.30 in 1999. While the crude oil price differentials between WTI and California's heavy crude has widened slightly over the last two years, the Company believes that the differential will be near its historical norms over the next several years. The crude price differential between WTI and California's heavy crude oil can be volatile and has averaged $7.25, $6.36 and $5.97 for 2001, 2000 and 1999, respectively. Berry markets its crude oil production to competing buyers including independent marketing, pipeline and oil refining companies. Primarily due to the Company's ability to deliver significant volumes of crude oil over a multi-year period, the Company was able to secure a three-year sales agreement, beginning in April 2000, with a major California refiner whereby the Company sells in excess of 80% of its production under a negotiated pricing mechanism. The agreement is based on a monthly determination of the highest price from any of (1) local field posted price plus a fixed bonus, (2) WTI minus a fixed differential or (3) a fixed percentage of WTI. In addition to providing a premium above field postings, the agreement effectively eliminates the Company's exposure to the risk of widening WTI-heavy crude price differentials. From time to time, the Company also enters into crude oil hedge contracts, the terms of which depend on various factors, including Management's view of future crude oil prices and the Company's future financial commitments. In May of 2001, the Company entered into a one-year zero cost bracketed collar on 3,000 barrels/day (BPD) of its crude oil. The maximum the Company was obligated to pay under the hedge was $3.62/Bbl and the maximum the Company could receive under the hedge was $5.60/Bbl. The counterparty to this hedge, Enron, filed for bankruptcy on December 2, 2001. As a result, the Company terminated this contract on December 10, 2001. During 2000, the Company maintained two bracketed zero cost collar hedge contracts with two refiners entered into in previous years as part of its price protection program. This price protection program was designed to moderate the effects of a severe price downturn while allowing Berry to participate in 100% of the upside after a maximum $3.00 per barrel payment on 6,500 BPD. Of this 6,500 BPD, Berry participated on 5,000 BPD above $15.50 per barrel and on 1,500 BPD above $17.50 per barrel. These price triggers were based on California heavy oil postings and both contracts expired at December 31, 2000. All of these price protection activities resulted in a net (benefit) or cost/Bbl to the Company of ($.16) in 2001, $1.31 in 2000 and $.51 in 1999. Berry's 2001 average heavy crude oil sales price was $19.70/Bbl, down $2.00, or 9% from $21.70 in 2000, and $13.08 in 1999. 4

The Company had no crude oil hedges in place at December 31, 2001. However, the Company has entered into oil price protection hedges in 2002 for a one-year period beginning April 1, 2002 on a total of 5,000 BPD. Based on WTI pricing, the hedges have a floor of approximately $20.00/Bbl and a ceiling of approximately $24.00/Bbl. In addition, its existing crude oil sales agreement does provide some protection against a severe price decline. One of the Company's properties, with production in excess of 3,000 BPD, is burdened by a price-sensitive royalty. The royalty is 75% of the heavy oil posted price above $14.30 (for 2002), escalated and calculated annually. Management regularly monitors the crude oil markets and its financial commitments to determine if, when, and at what level some form of crude oil hedging or other price protection is appropriate. Steaming Operations At December 31, 2001, approximately 94% of the Company's proved reserves, or 97 million barrels, consisted of heavy crude oil produced from depths averaging less than 2,000 feet. The Company, in achieving its goal of being a low-cost heavy oil producer, has focused on reducing its steam cost through the purchase of its 38 megawatt (Mw) cogeneration facility in 1995 and another 18 Mw cogeneration facility in 1996 as part of the purchase of additional oil properties in the South Midway-Sunset field. In early 1999, the Company purchased the Placerita oilfield, which is highly dependent on low-cost steam for economic production. This purchase also included a 42 Mw cogeneration facility consisting of two 21 Mw turbines. Steam generation from these facilities is more efficient than conventional steam generators, as both steam and electricity are produced from the same natural gas fuel supply. In addition, the Company's ownership of these facilities allows for control over the steam supply which is crucial for the maximization of oil production and ultimate reserve recovery. The Company believes that it may become advantageous to add additional productive steam capacity for its requirements at South Midway-Sunset and Placerita to allow for full development of its properties. While the Company vigorously pursued the possibility of constructing additional cogeneration facilities at various locations on its properties in 2001, the regulation of the electrical market in California is controlled by a very politically-oriented state government. The Company has been unsuccessful in obtaining an economic power sales agreement to date and has reduced its efforts regarding such contracts until the electrical marketplace in California becomes either less controlled by the state government or until the marketplace allows reasonable economics to prevail. Midway-Sunset Field For its South Midway-Sunset properties, the Company's steam production for 2001 was generated by its 38 Mw and 18 Mw cogeneration facilities (approximately 13,300 barrels of steam per day (BSPD) including duct-fire, 21,000 BSPD in 2000) and, as needed, from conventional steam generators. The Company also has a steam contract from an on-site, non-owned cogeneration facility for a minimum delivery of 2,000 BSPD for use in the Company's operations. Conventional steam generators are used by the Company as warranted to maintain current production levels, to economically produce additional crude oil and as emergency back- up steam generation to the cogeneration facilities. The Company has the capability of generating approximately 17,000 BSPD from conventional steam generators on its South Midway-Sunset properties. On its North Midway-Sunset properties, the Company relies solely on conventional steam generators, which have the capability of generating approximately 3,400 BSPD, for its steam requirements. Placerita On its Placerita properties, the Company generated approximately 8,600 BSPD in 2001 (12,500 BSPD in 2000) from its 42 Mw cogeneration facility and has the capability of generating another 7,600 BSPD from conventional steam generators. 5

Current Steam Output Conventional Steam Generation Effective December 1, 2000, the Company shut-in most of its conventional steam generation capacity due to an unprecedented increase in natural gas prices at the Southern California border (SoCal). The natural gas price for delivery into SoCal was $14.08/Million British Thermal Units (Mmbtu) in December 2000, versus an average of $2.74/Mmbtu in 1999. Historically, the SoCal natural gas price has tracked very close to the NYMEX Henry Hub (HH) price. The SoCal price exploded over HH in December 2000 by approximately $7.72/Mmbtu. This dramatic rise in natural gas prices made conventional steaming operations uneconomic and, thus, forced the Company to suspend most of its conventional steaming operations. High natural gas prices in California persisted into mid-2001. In August 2001, with SoCal prices at approximately $4.00/Mmbtu, the Company began generating steam from its conventional sources. For 2001, the cost of natural gas purchased averaged $5.76/Mmbtu versus $4.95/Mmbtu in 2000. On March 1, 2002, SoCal gas prices were approximately $2.40/Mmbtu. Cogeneration Steam Generation Going into 2001, the Company had four Standard Offer (SO) electricity sales contracts related to its three cogeneration plants. These contracts were based primarily on natural gas costs, thus, as fuel costs rose so did the electrical revenues. The actions that California's two largest utilities (Pacific Gas and Electric Company (PG&E) and Southern California Edison Company (Edison)) took in 2001 negatively impacted Berry and its operations. Edison failed to pay Berry for November 2000 through March 2001 power deliveries. PG&E made full payment for November 2000 and only partial payments, of approximately 15%, for December 2000 and January 2001 deliveries before filing for bankruptcy on April 6, 2001. As a result of non-payment, the Company was forced to suspend operations at its 38 Mw and Placerita Unit II (21 Mw) cogeneration facilities effective February 1, 2001. The Company also suspended operations at its 18 Mw cogeneration facility on February 17, 2001 and on Placerita Unit I (21 Mw) cogeneration facility on April 6, 2001. The PG&E bankruptcy judge approved Berry's contract terminations with PG&E in May of 2001 and on June 14, 2001, the Company was able to restart its 38 Mw and 18 Mw cogeneration facilities by selling its electricity to a creditworthy third party and began once again injecting steam into its heavy oil reservoir at its South Midway-Sunset field. 6

Although Berry terminated its two contracts with Edison in early 2001, Berry and Edison agreed to reinstate the contracts under a revised pricing structure whereby Edison agreed to prepay Berry for power deliveries. One contract continued to be based on the cost of natural gas plus capacity payment while the second contract has a fixed electricity sales price of 5.37 cents/kwh plus capacity payment. Accordingly, the Company refired both 21Mw cogeneration facilities on June 27, 2001, thereby again injecting steam into its heavy oil reservoir at its Placerita field. The Company believes that it will be able to deliver its power generation in 2002 to paying customers and anticipates steam generation volumes from its cogeneration facilities will be similar to its pre-2001 historical levels. Until the Company can re-establish economic long-term electricity sales contracts, the cost of the Company's steam may be volatile from quarter to quarter and year to year. The Company has physical access to gas pipelines, such as the Kern River/El Paso and Southern California Gas Company systems, to transport its gas purchases required for steam generation. The Company has no long-term gas delivery contracts and none of the Company's cogeneration facilities are subject to any long-term gas transportation agreements. Historically, there has been sufficient capacity to deliver adequate quantities of natural gas to the Company's properties, however, it appears that pipeline capacity into and within California was constrained in late 2000 and into 2001 and was at least partially responsible for higher natural gas prices in California. In early 2001, the Company subscribed to 12,000 Mmbtu/day of firm transportation for a ten-year term on the expansion project on the Kern River Pipeline. This project is expected to begin delivering gas in mid-2003, although the project is awaiting FERC approval. The Company has no assurance that it can procure its future natural gas requirements at reasonable prices, however, the natural gas constraint that occurred in late 2000 and early 2001 seems to have abated and recent SoCal gas prices are similar to Henry Hub prices. 6

(2) Approximate average for 2001 based on 365 day year and 2000 based on 366 day year. Electricity Generation The Company's three cogeneration facilities, when combined, have electricity production capacity of 98 Mw of electricity per hour. Each facility is centrally-located on an oil property such that the steam generated by the facility is capable of being delivered to the oil properties that require the steam for production purposes. With higher natural gas prices impacting its operations so significantly, the Company is pursuing other opportunities to secure additional long-term sources of low-cost steam. The Company's investments in its cogeneration facilities have been for the express purpose of lowering the steam costs in its heavy oil operations and securing operating control of the respective steam generation. Expenses of operating the cogeneration plants are analyzed monthly on a companywide basis. Any profits generated from cogeneration are considered profits from electricity generation. If the expenses exceed electricity revenues, the excess expenses are charged to oil and gas operating costs. During the fourth quarter of 2000, the Company experienced a significant increase in the cost of natural gas, which is used as a fuel for its cogeneration plants and steam generators. To protect itself from a pending proposed decision by the California Public Utilities Commission which would de-link the Company's natural gas cost from electricity sales under its standard offer contracts, the Company entered into several derivative contracts to hedge 4,500 Mmbtu/day of natural gas purchases for the three months ended March 31, 2001. During December 2000, the Company recorded operating costs of $.3 million related to the ineffective portion of these derivative instruments and $.4 million (net of tax effects) in other comprehensive income related to unrecognized gains from these derivative instruments. In 2001, the Company earned $1.4 million pre-tax from these hedges which was recorded as a reduction to "Operating cost - electricity generation". See Notes 2 and 3 of Notes to the Financial Statements. One of the Company's major challenges in 2001 was to obtain the necessary approvals to sell the Company's electricity into the marketplace and enter into a contract to sell power to a creditworthy buyer. The Company terminated its two contracts with PG&E on April 2, 2001, just four days before PG&E filed for bankruptcy. On May 16, 2001, the PG&E bankruptcy judge approved a settlement that the Company had reached with PG&E whereby the utility would allow the Company to sell its power into the grid. The Company immediately entered into a sales agreement with a creditworthy third party and is delivering electricity into the grid primarily via spot sales. The Company also pursues monthly or longer-term sales arrangements. In September 2001, the Company assigned its PG&E past-due receivables to a third party for cash in the amount of $9.3 million. 7

Berry also terminated its two contracts with Edison, and when Edison refused to acknowledge such terminations, Berry filed the necessary lawsuits. In June 2001, Berry and Edison reached a settlement whereby Edison would prepay Berry for power deliveries and whereby Berry agreed to "standstill" on litigation matters until December 31, 2001. Berry's Placerita II contract, which expires in May 2002, stayed on a short-run avoided cost (SRAC) pricing mechanism. Berry chose to elect the five-year fixed price of 5.37 cents per kilowatt hour pricing mechanism on its Placerita I contract, which expires in March 2009. These contract amendments were approved by the CPUC in July 2001. The Company entered into two additional contract amendments with Edison whereby 1) the Company received 10% of the past-due amount and 7% accrued interest on the past-due amount, and 2) the Company extended its litigation standstill to allow Edison to become creditworthy and Edison devised a formula payment, although no specific date for payment was established. The Company received interest monthly on the past due amount. At December 31, 2001, Edison owed the Company $13.5 million and Berry had $9.3 million recorded as collectible receivables; the difference was written-off in early 2001. On March 1, 2002, Edison paid the Company $13.5 million, representing the total past due amount plus interest. The Company will record pre-tax income of $4.2 million in the first quarter of 2002 related to this cash receipt. In late July 2001, Berry entered into a three-year SoCal gas swap with Enron for a price of $4.20/Mmbtu on 5,000 Mmbtu/day. The Company terminated this hedge contract with Enron on December 10, 2001, shortly after Enron declared bankruptcy and at the same time, the Company terminated its crude oil price hedge with Enron. The Company anticipates that it will enter into a similar gas purchasing hedge in the near future to protect its favorable spark spread related to Edison's fixed price contract. Impact of Enron Bankruptcy As previously described in "Oil Marketing" and "Electricity Generation" the Company had commodity derivative contracts, both oil and natural gas, in place when Enron declared bankruptcy on December 2, 2001. On December 10, 2001, the Company elected to terminate all contracts with Enron and agreed with Enron as to the value of the contracts as of termination. Based on this agreed value, the Company recorded a pre-tax charge of $1.5 million in the fourth quarter of 2001 and recorded a liability of $1.3 million which is anticipated to be remitted upon the approval of the termination agreement by the Enron bankruptcy judge. The Company had a signed International Swap Dealer's Association (ISDA) master agreement with Enron which allowed for the netting of any receivables and liabilities arising thereunder. Environmental and Other Regulations Berry Petroleum Company is committed to responsible management of the environment, health and safety, as the environment as the Company strives to achieve the long-term goal of sustainable development. Berry makes environmental, health and safety protection an integral part of all business activities, from the acquisition and management of its resources through the decommissioning and reclamation of its wells and facilities. With safety protection one of the key focuses, the Company has gone almost three years without a lost-time accident by any of its employees. The oil and gas production business in which Berry participates is complex. All facets of the Company's operations are affected by a myriad of federal, state, regional and local laws, rules and regulations. Berry is further affected by changes in such laws and by constantly changing administrative regulations. Furthermore, government agencies may impose substantial liabilities if the Company fails to comply with such regulations or for any contamination resulting from the Company's operations. Therefore, Berry has programs in place to address risks, to train employees in the proper performance of their duties and to incorporate viable new technologies. The costs incurred to ensure compliance with environmental, health and safety laws and other regulations are inextricably connected to normal operating expenses such that the Company is unable to separate the expenses related to these matters. Currently, California environmental laws and regulations are being revised to provide for additional emission reductions. Although these requirements do have a substantial impact upon the energy industry, generally these requirements do not appear to affect the Company any differently, or to any greater or lesser extent, than other companies 8

in California. Berry believes that compliance with environmental laws and regulations will not have a material adverse effect on the Company's operations or financial condition. There can be no assurances, however, that changes in, or additions to, laws and regulations regarding the protection of the environment will not have such an impact in the future. Berry maintains insurance coverage that it believes is customary in the industry although it is not fully insured against all environmental or other risks. The Company is not aware of any environmental claims existing as of December 31, 2001 that would have a material impact upon the Company's financial position, results of operations, or liquidity. Competition The oil and gas industry is highly competitive. As an independent producer, the Company does not own any refining or retail outlets and, therefore, it has little control over the price it receives for its crude oil. As such, higher costs, fees and taxes assessed at the producer level cannot necessarily be passed on to the Company's customers. In acquisition activities, significant competition exists as integrated and independent companies, individual producers and operators are active bidders for desirable oil and gas properties. Although many of these competitors have greater financial and other resources than the Company, Management believes that Berry is in a position to compete effectively due to its low cost structure, transaction flexibility, strong financial position, experience and determination. Employees On December 31, 2001, the Company had 110 full-time employees, down from 115 employees at year-end 2000. Oil and Gas Properties Development Midway-Sunset - Berry owns and operates working interests in 35 properties consisting of 3,985 acres located in the Midway- Sunset field. The Company estimates these properties account for approximately 74% of the Company's proved oil and gas reserves and approximately 74% of its current daily production. Of these properties, 18 are owned in fee. The wells produce from an average depth of approximately 1,200 feet, and rely on thermal EOR methods, primarily cyclic steaming. During 2001, like 2000, the primary focus at Midway-Sunset was continued development of the Formax properties acquired in 1996 and the continued application of horizontal well technology in the Monarch sands. Of the 34 wells drilled in this field in 2001, 17 were drilled on the Formax properties, and 13 were horizontal wells. The Company's objectives using this innovative technology are to improve ultimate recovery of original oil-in- place, reduce the development and operating costs of the properties and accelerate production. In 2002, the Company plans to drill an additional 39 wells in this field, including 13 on the Formax properties, 11 of which will be horizontal. Included in the Company's 2002 development plans for Midway- Sunset are seven exploitation wells, in both the North and South Midway-Sunset areas. In the North Midway-Sunset area, a corehole will be drilled to evaluate the extent of the diatomite accumulation in addition to four delineation wells to evaluate the extent of our 2001 step-out discovery in the Upper Tulare Zone. Placerita - The Placerita property consists of six leases (three federal) and three fee properties totaling approximately 750 acres. The Company estimates current reserves from Placerita account for approximately 20% of Berry's proved oil and gas reserves and approximately 19% of Berry's daily production. The average depth of these wells is 1,800 feet and the properties rely extensively on thermal methods, primarily steam flooding. During 2001, the Company drilled three wells at Placerita, one of which was a water disposal service well. The other two wells were the first wells drilled as Phase One of a major development campaign at the north end of the field. Included in the Company's 2002 development plans for Placerita is the continuation of the north end development with four steamflood injection wells, three steamflood producers, and a step-out evaluation well. 9

Montalvo - Berry owns a 100% working interest in six leases, totaling 8,563 acres, in Ventura County, California comprising the entire Montalvo field. The State of California is the lessor for two of the six leases. The Company estimates current proved reserves from Montalvo account for approximately 5% of Berry's proved oil and gas reserves and approximately 7% of Berry's daily production. The wells produce from an average depth of approximately 11,500 feet. No new wells were drilled in 2001. There are no plans at this time to drill any new wells in 2002, however one remedial is planned. We are also pursuing the possibility of running a seismic program over selected portions of the developed area of the field in 2002 to confirm suspected bypassed oil and gas accumulations in this highly faulted, geologically complex field. South Joe Creek - In April 2001, Berry purchased a 15.83% non-operated working interest in the South Joe Creek coalbed methane field. The Company purchased interests in federal, state and local leases totaling approximately 5,800 acres in the Campbell County portion of the Powder River Basin in Wyoming. There were 18 wells (3 net) in existence at the time of the purchase and 67 additional wells (11 net) were drilled in 2001. Another 19 wells (3 net) are planned for drilling and completion in 2002. On February 10, 2002, the production rate was 6.62 million cubic feet of gas (1.05 net) per day. The following is a summary of the Company's capital expenditures incurred during 2001 and 2000 and projected capital expenditures for 2002.

Exploration The Company did not participate in the drilling of any exploratory wells in 2001 or 2000 and has none budgeted for 2002. In recent years, the Company has concentrated on growth through development of existing assets and strategic acquisitions. The Company is pursuing an acquisition strategy which may include some exploration drilling in the future. Enhanced Oil Recovery Tax Credits The Revenue Reconciliation Act of 1990 included a tax credit for certain costs associated with extracting high-cost, capital- intensive marginal oil or gas and which utilizes at least one of nine designated "enhanced" or tertiary recovery methods. Cyclic steam and steam drive recovery methods for heavy oil, which Berry utilizes extensively, are qualifying EOR methods. In 1996, California conformed to the federal law, thus, on a combined basis, the Company is able to achieve credits approximating 12% of its qualifying costs. The credit is earned for only qualified EOR projects by investing in one of three types of expenditures: 1) drilling development wells, 2) adding facilities that are integrally related to qualified EOR production, or 3) utilizing a tertiary injectant, such as steam, to produce oil. The credit may be utilized to reduce the Company's tax liability down to, but not below, its alternative minimum tax liability. This credit is significant in reducing the Company's income tax liabilities and effective tax rate. Oil and Gas Reserves The Company continued to engage DeGolyer and MacNaughton (D&M) to estimate the proved oil and gas reserves and the future net revenues to be derived from properties of the Company for the year ended December 31, 2001. D&M is an independent oil and gas consulting firm located in Dallas, Texas. In preparing their reports, D&M reviewed and examined geologic, economic, engineering and other data considered applicable to properly determine the reserves of the Company. They also examined the reasonableness of certain economic assumptions regarding forecasted operating and development costs and recovery rates in light of the economic environment on December 31, 2001. For the Company's operated properties, these reserve estimates are filed annually with the U.S. Department of Energy. Refer to the Supplemental Information About Oil & Gas Producing Activities (Unaudited) for the Company's oil and gas reserve disclosures. Production The following table sets forth certain information regarding production for the years ended December 31, as indicated: 2001 2000 1999 Net annual production:(1) Oil (Mbbls) 4,996 5,434 5,060 Gas (Mmcf) 288 199 180 Total equivalent barrels(2) 5,044 5,467 5,090 Average sales price: Oil (per Bbl) $19.70 $21.70 $13.08 Gas (per mcf) 5.09 4.34 1.90 Per BOE 19.79 21.72 13.07 Average operating cost - oil and gas 7.99 8.20 5.47 production (per BOE)(3) (1) Net production represents that owned by Berry and produced to its interest, less royalty and other similar interests. (2) Equivalent oil and gas information is at a ratio of 6 thousand cubic feet (mcf) of natural gas to 1 barrel (Bbl) of oil. A barrel of oil (Bbl) is equivalent to 42 U.S. gallons. (3) Includes monthly expenses in excess of monthly revenues from cogeneration operations (per BOE) of $1.31, $0.53 and $0 for 2001, 2000 and 1999, respectively. See Note 2 to the financial statements. 11

Acreage and Wells At December 31, 2001, the Company's properties accounted for the following developed and undeveloped acres: Developed Acres Undeveloped Acres Gross Net Gross Net California 7,226 7,226 7,244 7,244 Other 3,720 573 1,746 277 ------ ------ ------ ------ 10,946 7,799 8,990 7,521 ====== ====== ====== ====== Gross acres represent acres in which Berry has a working interest; net acres represent Berry's aggregate working interests in the gross acres. Berry currently has 2,466 gross oil wells (2,461 net) and 88 gross gas wells (17 net). Gross wells represent the total number of wells in which Berry has a working interest. Net wells represent the number of gross wells multiplied by the percentages of the working interests owned by Berry. One or more completions in the same bore hole are counted as one well. Any well in which one of the multiple completions is an oil completion is classified as an oil well. Drilling Activity The following table sets forth certain information regarding Berry's drilling activities for the periods indicated: 2001 2000 1999 Gross Net Gross Net Gross Net Exploratory wells drilled: Productive - - - - - - Dry(1) - - - - - - Development wells drilled:(2) Productive 103 47 81 81 21 21 Dry(1) 1 - - - - - Total wells drilled: Productive 103 47 81 81 21 21 Dry(1) 1 - - - - - (1) A dry well is a well found to be incapable of producing either oil or gas in sufficient quantities to justify completion as an oil or gas well. (2) Wells drilled for 2001 include 67 wells gross, 11 wells net that were drilled at South Joe Creek which the Company acquired in 2001 and holds a 15.83% working interest. Title and Insurance To the best of the Company's knowledge, there are no defects in the title to any of its principal properties including related facilities. Notwithstanding the absence of a recent title opinion or title insurance policy on all of its properties, the Company believes it has satisfactory title to its properties, subject to such exceptions as the Company believes are customary and usual in the oil and gas industry and which the Company believes will not materially impair its ability to recover the proved oil and gas reserves or to obtain the resulting economic benefits. The oil and gas business can be hazardous, involving unforeseen circumstances such as blowouts or environmental damage. Although it is not insured against all risks, the Company maintains a comprehensive insurance program to address the hazards inherent in operating its oil and gas business. 12

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations The following discussion provides information on the results of operations for each of the three years ended December 31, 2001, 2000 and 1999 and the financial condition, liquidity and capital resources as of December 31, 2001 and 2000. The financial statements and the notes thereto contain detailed information that should be referred to in conjunction with this discussion. The profitability of the Company's operations in any particular accounting period will be directly related to the average realized prices of oil, gas and electricity sold, the type and volume of oil and gas produced and electricity generated and the results of acquisition, development, exploitation and exploration activities. The average realized prices for natural gas and electricity will fluctuate from one period to another due to regional market conditions and other factors, while oil prices will be predominantly influenced by world supply and demand. The aggregate amount of oil and gas produced may fluctuate based on the success of development and exploitation of oil and gas reserves pursuant to current reservoir management. The cost of natural gas used in the Company's steaming operations and electrical generation, production rates, labor, maintenance expenses and production taxes are expected to be the principal influences on operating costs. Accordingly, the results of operations of the Company may fluctuate from period to period based on the foregoing principal factors, among others. Results of Operations The Company earned $21.9 million, or $1.00 per share, in 2001, down 41% from $37.2 million, or $1.69 per share, in 2000, but up 22% from $18 million, or $.82 per share in 1999. Income earned in 2001 represents the second highest income ever achieved by the Company, exceeded only by the $37.2 million earned in 2000. The decrease in income from 2000 was primarily related to lower crude oil prices and lower production which was a direct result of the suspension of steam operations in 2001 due to the California energy crisis and the writedown of electricity receivables from two of California's insolvent public utilities. The following table presents certain operating data for the years ended December 31, 2001, 2000 and 1999: 2001 2000 1999 Oil and Gas Net production - BOE/D 13,820 14,937 13,946 Per BOE: Average sales price $19.79 $21.72 $13.07 Operating costs(1) 7.50 7.77 4.95 Production taxes .49 .43 .52 Total operating costs 7.99 8.20 5.47 DD&A 3.28 2.57 2.42 G&A 1.42 1.42 1.23 Interest expense .74 .58 .78 Electricity Electric power produced - megawatt (Mw) hrs/day 1,251 1,979 1,957 Average sales price/Mw $78.68 $72.85 $47.22 Fuel gas cost/Mmbtu 5.76 4.95 2.74 (1) Including monthly expenses in excess of monthly revenues from cogeneration operations of $1.31, $0.53 and $0 in 2001, 2000 and 1999, respectively. BOE/D - Barrels of oil equivalent per day 16

Operating income from oil and gas producing operations was $42.2 million in 2001, down from $60.3 million in 2000, but up from $26.8 million in 1999. The decrease from 2000 was primarily due to lower sales of oil and gas and higher DD&A, partially offset by lower operating costs. Sales of oil and gas were $100.1 million in 2001, down from $118.8 million in 2000, but higher than $66.6 million in 1999. The decrease from 2000 was related to both lower production and sales prices and the increase from 1999 was due to higher oil prices partially offset by slightly lower production. Production in 2001 at 13,820 BOE/D was 7% and 1% lower than 14,937 in 2000 and 13,946 in 1999, respectively. Production for 2001 peaked at approximately 16,000 BOE/D in the first quarter before the effects of the suspension of steaming operations took effect. The extremely high natural gas costs during the California energy crisis and the suspension of utility payments for cogeneration power made steaming uneconomic for several months in the first half of 2001. The Company was forced to curtail conventional steaming operations in late 2000 and suspend the majority of its cogeneration operations in February 2001 with the remaining turbine shut-in in early April. In June, the Company began increasing its steaming activities, with normal injection levels re-established in August. Due to the steam curtailment, crude oil production fell to a low of approximately 12,800 BOE/D before recovering to a level of approximately 14,000 BOE/D at year-end. The Company expects 2002 crude oil production levels to average approximately 15,000 BOE/D. Oil prices for 2001 were quite strong until the aftermath of September 11 reduced worldwide demand for crude oil and refined products. The average price received/BOE in 2001 of $19.79 was only slightly lower than $21.72 in 2000 and was 51% higher than $13.07 received in 1999. Post September 11, crude oil prices fell $9/Bbl to a low of $11.00 for California heavy oil but subsequently rebounded to $13.25/Bbl at year-end and to $15.25 as of February 13, 2002. Operating costs per barrel in 2001 were $7.99, down from $8.20 in 2000, but higher than $5.47 in 1999. The most significant factor in the reduction of operating costs from 2000 was the suspension of steaming operations. Not only was the cost of gas dramatically reduced, but other factors in the Company's cost structure, such as production rig cost, chemicals for water treating and other areas were greatly diminished or eliminated for the period in which steaming was suspended. Although the suspension was a positive factor in lowering operating costs in 2001, it did, of course, come at the cost of declining production levels. Other factors contributing to the decline in operating costs were the 3D project performed on the Company's Midway- Sunset properties in 2000, higher environmental remediation costs in 2000 and savings from facility consolidation projects on several of the Company's core properties in 2001. It should be pointed out that in the period of suspended cogeneration operations, it was necessary to purchase additional electricity from two California utilities at very high per unit costs which resulted in an increase in power costs of approximately $1.1 million over 2000 levels. The Company estimates that the operating cost per barrel in 2002 will average $7.00 to $8.00 given the current development plan and operating environment. The Company has seen a drastic decline in electricity prices during 2001. Although the average price received for the Company's power was comparable at $.078/Kwh for both 2000 and 2001, the trend in electricity pricing is toward much lower prices which had a negative impact on the Company's steam costs in the fourth quarter of 2001 and will also affect 2002 costs and beyond. Although the Company has negotiated electricity sales contracts on its two Placerita turbines at attractive prices, the remaining electricity generated is sold on the open market which currently has been priced at just $.025/Kwh. As the Company entered 2001, the California energy crisis was just unfolding. Two of the state's major utilities were experiencing extreme cash flow problems related to their inability to pass their cost to obtain electricity to retail and industrial customers. Therefore, in the early portion of 2001, these two utilities suspended payment for electric power produced by the Company under longstanding Standard Offer contracts. The Company was forced to take actions to protect the liquidity of the Company. Prior to Pacific Gas and Electric Company's (PG&E) bankruptcy, the Company terminated its power purchase contracts with PG&E. The Bankruptcy Court confirmed these terminations and Berry paid $.2 million pursuant to the settlement and stipulation with PG&E. In June 2001, the Company entered into a contract with a creditworthy power marketer and re-established power production from its homebase cogeneration capacity. In September 2001, the Company assigned its past-due receivables for approximately 77% of the balance owed by PG&E which effectively ended the Company's direct involvement with PG&E's default. The Company filed litigation against Edison and the California Independent System Operator (ISO) on May 2 and May 7, 2001 to recover non-payment for deliveries of electricity from November 2000 through March 2001 and to resolve other contractual matters. The lawsuits were ultimately coordinated with those of other "qualified facilities" and, on June 27, 2001, the Company and Edison entered into amendments with respect to its existing Power Purchase Agreements which 17

became effective on July 18, 2001. The amendments provided for a standstill of litigation and other matters. On August 27, 2001, the Company entered into Implementing Agreements concerning these amendments requiring the suspension of legal proceedings during the agreed to "Standstill Period". The above agreements were approved by the Court on September 19, 2001. One of the two agreements will expire under its own terms in May 2002, at which time the Company will need to make other arrangements for the sale of the corresponding electricity production. The Standstill Period was extended by a further amendment on December 10, 2001 and a payment formula was established whereby Edison was to make payments, although there was no date identified. Additionally, Edison was required to make monthly payments in advance for power to be delivered and to make interest payments on the outstanding balance until the balance is paid or the amendments terminate. On March 1, 2002, Edison paid the Company $13.5 million, representing the total past-due amount plus interest. The Company will record pre-tax income of $4.2 million in the first quarter of 2002 related to this cash receipt. At year-end the Company had no commodity hedges in place. In December, the Company terminated its crude oil and natural gas derivative contracts with Enron and recognized a net pre-tax loss on termination of these contracts of $1.5 million. The Company anticipates that it will enter into similar gas purchase hedges in the near future in an effort to manage its "spark spread" (the difference between the price received for the sale of electricity and the cost of natural gas) and lower its operating costs. DD&A on a per barrel basis increased to $3.28, up from $2.57 in 2000 and $2.42 in 1999. The increase from prior years was primarily due to a higher depreciable basis resulting from the 2001 and 2000 development activity and facility improvements at the Company's cogeneration facilities and the amortization of the remaining capitalized costs related to the Standard Offer electricity sales contracts which were terminated in 2001. The Company expects DD&A to be slightly lower in 2002 compared to 2001. General G&A expenses in 2001 were $7.2 million, or $1.42 per BOE, down 8% from $7.8 million in 2000, but up 14% from $6.3 million in 1999. The decrease from 2000 was primarily the result of lower personnel costs, legal expenses and consulting charges. The Company expects similar G&A expenses in 2002 compared to 2001. Interest expense increased in 2001 to $3.7 million from $3.2 million in 2000, but decreased from $4.0 million in 1999. To ensure liquidity, the Company drew down $45 million from its credit facility in early 2001 to compensate for the large unpaid receivables from electricity sales in late 2000 and the early months of 2001. The receivable for one of the two utilities was sold in the third quarter eliminating approximately half of the remaining receivable balance. These funds and internally generated funds were sufficient to pay off the $45 million drawdown by the end of the third quarter of 2001. The debt repayment along with much lower interest rates has resulted in lower interest costs incurred thus far in 2002 compared to the average rate experienced in 2001. The Company experienced an effective income tax rate of 19.5% in 2001, down from 28% and 21% in 2000 and 1999, respectively. The lower effective tax rate is primarily a result of significant enhanced oil recovery (EOR) tax credits earned by the Company's continued investment in the development of its thermal EOR projects, both through capital expenditures and continued steam injection volumes. This is the fourth consecutive year that the Company has achieved an effective tax rate below 30%, versus the combined federal and state statutory rate of 40%. The Company believes it will continue to earn significant EOR tax credits and have an effective tax rate below 30% in 2002. Financial Condition, Liquidity and Capital Resources Working capital at December 31, 2001 was $5.8 million, up from ($1.2) million at December 31, 2000, but down from $8.4 million in 1999. Net cash provided by operations was $35.4 million, down 46% from the all-time record of $65.9 million achieved in 2000, but 43% higher than $24.8 million in 1999. The Company used these funds to pay for capital expenditures of $14.9 million, pay dividends of $8.8 million, acquire an interest in producing properties and drillable acreage of $2.3 million and increase the company's cash balance by $4.5 million to a healthy balance of $7.2 million at December 31, 2001. The Company's net debt (i.e., its outstanding long-term debt of $25 million less working capital) was $19.2 million. 18

The Company has a $150 million revolving bank facility with a banking group. As of December 31, 2001, approximately $118 million is available under the agreement after deducting the $25 million long-term debt and $6.7 million in outstanding Letters of Credit. As of June 30, 2001, the Company was owed $15.0 million by Edison for power produced between November 2000 and March 2001. In the third quarter of 2001, $1.5 million of the total was received, leaving a remaining balance of $13.5 million as of December 31, 2001. Of this balance, $9.3 million was recorded as collectible receivables at December 31, 2001. On March 1, 2002, Edison paid the Company $13.5 million, representing the total amount due plus interest. The Company presently intends to use these funds to reduce its long-term debt of $25 million to approximately $12 million. In August 2001, the Board of Directors authorized the Company to repurchase $20 million of Common Stock in the open market. As of December 31, 2001, the Company had repurchased 308,075 shares for approximately $5.1 million. All shares repurchased were retired. The Company has budgeted $19.6 million in capital projects in 2002 consisting of the drilling of 52 Company operated wells on its core California properties, 11 of which will be horizontal, and 33 non-operated (gross wells) in the South Joe Creek field in Wyoming. The development program will also include 31 remedial jobs and other facility improvements of $6.4 million all at the Company's core California properties. At year-end, the Company had no subsidiaries, no special purpose entities and no off-balance sheet debt. The Company did not enter into any significant related party transactions in 2001. Critical Accounting Policies The preparation of financial statements in conformity with generally accepted accounting principles requires Management to make estimates and assumptions for the reporting period and as of the financial statement date. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities and the reported amounts of revenues and expenses. Actual results could differ from those amounts. A critical accounting policy is one that is important to the portrayal of the Company's financial condition and results, and requires Management to make difficult subjective and/or complex judgments. Critical accounting policies cover accounting matters that are inherently uncertain because the future resolution of such matters is unknown. The Company believes the following accounting policies are critical policies; accounting for oil and gas reserves, environmental liabilities, income taxes and asset retirement obligations. Oil and gas reserves include proved reserves that represent estimated quantities of crude oil and natural gas in which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. The oil and gas reserves are based on estimates prepared by independent engineering consultants and are used to calculate DD&A and determine if any potential impairment exists related to the recorded value of the Company's oil and gas properties. The Company reviews, on a quarterly basis, its estimates of costs of compliance with environmental laws and the cleanup of various sites, including sites in which governmental agencies have designated the Company as a potentially responsible party. When it is probable that obligations have been incurred and where a minimum cost or a reasonable estimate of the cost of compliance or remediation can be determined, the applicable amount is accrued. The Company makes certain estimates, which may include various tax planning strategies, in determining taxable income, the timing of deductions and the utilization of tax attributes. Management is required to make judgments based on historical experience and future expectations on the future abandonment cost, net of salvage value, of its oil and gas properties and equipment. The Company reviews its estimate of the future obligation periodically and accrues the estimated obligation monthly based on the units of production method. 19

Impact of Inflation The impact of inflation on the Company has not been significant in recent years because of the relatively low rates of inflation experienced in the United States. Recent Accounting Developments In July 2001, the Financial Accounting Standards Boards (FASB) issued SFAS No. 141, "Business Combinations," which supersedes Accounting Principles Board Opinion (APB) No. 16, "Business Combinations." This Statement requires that all business combinations be accounted for by the purchase method, establishes specific criteria for the recognition of intangible assets separately from goodwill and requires unallocated negative goodwill to be written off immediately as an extraordinary gain. The provisions of the Statement apply to business combinations initiated after June 30, 2001. For business combinations accounted for using the purchase method before July 1, 2001, the provisions of this Statement will be effective in the first quarter of 2002. The Company anticipates that the impact of this new standard will have an immaterial impact on the financial statements taken as a whole. In July 2001, the Financial Accounting Standard Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 142, "Goodwill and Other Intangible Assets," which supersedes the Accounting Principles Board (APB) Opinion No. 17, "Intangible Assets." This Statement addresses the accounting and reporting of goodwill and other intangible assets subsequent to their acquisition. The Statement also provides specific guidance on testing goodwill and intangible assets for impairment. SFAS No. 142 provides that (i) goodwill and indefinite-lived intangible assets will no longer be amortized, (ii) impairment will be measured using various valuation techniques based on discounted cash flows, (iii) goodwill will be tested for impairment at least annually at the reporting unit level, (iv) intangible assets deemed to have an indefinite life will be tested for impairment at least annually and (v) intangible assets with finite lives will be amortized over their useful lives. All provisions of this Statement will be effective in the first quarter of 2002. The Company anticipates that the impact of this new standard will have an immaterial impact on the financial statements taken as a whole. In August 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement Obligations," which addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. This Statement requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. All provisions of this Statement will be effective at the beginning of fiscal 2003. The Company is in the process of determining the impact of this standard on the Company's financial results when effective. In October 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." This Statement supersedes SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of" and amends APB No. 30, "Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions." This Statement requires that long-lived assets that are to be disposed of by sale be measured at the lower of book value or fair value less costs to sell. SFAS No. 144 retains the fundamental provisions of SFAS 121 for (a) recognition and measurement of the impairment of long-lived assets to be held and used and (b) measurement of long-lived assets to be disposed of by sale. This Statement also retains APB No. 30's requirement that companies report discontinued operations separately from continuing operations. All provisions of this Statement will be effective in the first quarter of 2002. The Company anticipates that the impact of this new standard will have an immaterial impact on the financial statements taken as a whole. 20

Item 7A. Quantitative and Qualitative Disclosures About Market Risk The Company has significant market risk exposure related to the prices received for the sale of its crude oil. A $1 change in oil price will equate to an approximately $5.5 million change in annual revenues. The Company periodically enters into hedge contracts to manage the oil price risk. The Company had no crude oil hedges in place at December 31, 2001. However, the Company has entered into oil price protection hedges in 2002 for a one- year period beginning April 1, 2002 on a total of 5,000 BPD. Based on WTI pricing, the hedges have a floor of approximately $20.00/Bbl and a ceiling of approximately $24.00/Bbl. The Company is also at risk for a widening of the differential between the WTI crude oil price and the posted price of the Company's heavy crude oil. To minimize this risk, the Company has a sales contract in place through March 31, 2003 for over 80% of its crude oil production which is priced at the higher of (1) local field posting plus a bonus, (2)WTI minus a fixed differential or (3)a fixed percentage of WTI. The Company also has market risk exposure related to the price received for the sale of its electricity production and the cost paid by the Company for the natural gas used in its cogeneration operations. The Company's three cogeneration facilities, when combined, have electricity production capacity of 98 Mw of electricity/hour (Mwh). Of this total, the Company sells approximately 92 Mwh and the remaining 6 Mwh is consumed in the Company's operations. The Company's goal is to control its "spark spread" (the difference between the sales price received for its electricity and the cost to purchase natural gas used as fuel in the cogeneration operations). This was an extremely difficult goal to achieve during 2001 primarily due our early electrical contract terminations arising out of the utility purchasers' default and the volatility in the electrical market and in natural gas prices. The Company consumes approximately 27,000 Mmbtu/day of natural gas as fuel in these facilities. A change of $.10/Mmbtu in the cost of natural gas equates to a change of approximately $1.0 million in operating costs. The Company has a long-term electricity sales contract in place at a fixed price of $53.70/Mwh plus capacity on approximately 19 Mwh of electricity production with a major utility. A change of $1/Mwh in the price received for electricity on the remaining 73 Mwh equates to approximately $.6 million in annual revenues. The Company is a party to another electricity sales contract for approximately 19 Mwh that is based on a short-run avoided cost (SRAC) pricing mechanism. This provides the Company an electricity price that is directly related to the cost of natural gas. However, this contract terminates in May 2002, whereupon this volume may be sold on the open market. The remainder of the electricity is sold primarily on the open market to a creditworthy customer. As the electricity market stabilizes in California, the Company anticipates entering into longer-term sales contracts for its electricity. The Company was able to enter into a four-month sales contract through June 30, 2002 under which the Company will deliver 25 Mwh of electricity, plus a cash payment, in exchange for a sufficient volume of natural gas needed to generate the 25 Mwh of electricity to fulfill the contract, thereby protecting the spark spread on this volume. The Company is pursuing longer- term arrangements on the sale of its electricity and may enter into additional hedges on its natural gas purchases to seek to improve the spark spread related to these non-utility volumes.

BERRY PETROLEUM COMPANY Notes to the Financial Statements 1. General The Company is an independent energy company engaged in the production, development, acquisition, exploitation and exploration of crude oil and natural gas. Substantially all of the Company's oil and gas reserves are located in California. Approximately 99% of the Company's production is heavy crude oil, which is principally sold to other oil companies, pipeline companies or refiners. The Company has invested in cogeneration facilities which provides steam required for the extraction of heavy oil and which generates electricity for sale. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. 2. Summary of Significant Accounting Policies Cash and cash equivalents The Company considers all highly liquid investments purchased with a remaining maturity of three months or less to be cash equivalents. Short-term investments All short-term investments are classified as available for sale. Short-term investments consist principally of United States treasury notes and corporate notes with remaining maturities of more than three months at date of acquisition. Such investments are stated at cost, which approximates market. The Company utilizes specific identification in computing realized gains and losses on investments sold. Oil and gas properties, buildings and equipment The Company accounts for its oil and gas exploration and development costs using the successful efforts method. Under this method, costs to acquire and develop proved reserves and to drill and complete exploratory wells that find proved reserves are capitalized and depleted over the remaining life of the reserves using the units-of-production method. Exploratory dry hole costs and other exploratory costs, including geological and geophysical costs, are charged to expense when incurred. The costs of carrying and retaining unproved properties are also expensed when incurred. Depletion of oil and gas producing properties is computed using the units-of-production method. Depreciation of lease and well equipment, including cogeneration facilities and other steam generation equipment and facilities, is computed using the units- of-production method or on a straight-line basis over estimated useful lives ranging from 10 to 20 years. The estimated costs, net of salvage value, of plugging and abandoning oil and gas wells and related facilities are accrued using the units-of- production method and are taken into account in determining DD&A expense. Buildings and equipment are recorded at cost. Depreciation is provided on a straight-line basis over estimated useful lives ranging from 5 to 30 years for buildings and improvements and 3 to 10 years for machinery and equipment. Assets are grouped at the field level and if it is determined that the book value of long-lived assets cannot be recovered by estimated future undiscounted cash flows, they are written down to fair value. When assets are sold, the applicable costs and accumulated depreciation and depletion are removed from the accounts and any gain or loss is included in income. Expenditures for maintenance and repairs are expensed as incurred. 28

BERRY PETROLEUM COMPANY Notes to the Financial Statements 2. Summary of Significant Accounting Policies (cont'd) Environmental Expenditures The Company reviews, on a quarterly basis, its estimates of costs of compliance with environmental laws and the cleanup of various sites, including sites in which governmental agencies have designated the Company as a potentially responsible party. When it is probable that obligations have been incurred and where a minimum cost or a reasonable estimate of the cost of compliance or remediation can be determined, the applicable amount is accrued. For other potential liabilities, the timing of accruals coincides with the related ongoing site assessments. Liabilities are not discounted. Hedging From time to time, the Company utilizes options, swaps and collars (derivative instruments) to manage its commodity price risk. On October 1, 2000, the Company adopted Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative Instruments and Hedging Activities", which established new accounting and reporting requirements for derivative instruments and hedging activities. SFAS No. 133, as amended by SFAS No. 138, requires that all derivative instruments subject to the requirements of the statement be measured at fair value and recognized as assets or liabilities in the balance sheet. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation is generally established at the inception of a derivative. For derivatives designated as cash flow hedges and meeting the effectiveness guidelines of SFAS No. 133, changes in fair value, to the extent effective, are recognized in other comprehensive income until the hedged item is recognized in earnings. Hedge effectiveness is measured at least quarterly based on the relative changes in fair value between the derivative contract and the hedged item over time, or in the case of options based on the change in intrinsic value. Any change in fair value of a derivative resulting from ineffectiveness or an excluded component of the gain/loss, such as time value for option contracts, is recognized immediately as operating costs in the statement of operations. See Note 3 - Fair Value of Financial Instruments. Cogeneration Operations The Company operates cogeneration facilities to help minimize the cost of producing steam, which is a necessity in its thermal oil and gas producing operations. Such cogeneration operations produce electricity as a by-product from the production of steam. In each monthly accounting period, the cost of operating the cogeneration facilities, up to the amount of the electricity sales, is considered operating costs from electricity generation. Costs in excess of electricity revenue during each period, if any, are considered cost of producing steam and are reported in Operating costs - oil and gas production. Conventional Steam Costs The costs of producing conventional steam are included in operating costs - oil and gas production. Revenue Recognition Revenues associated with sales of crude oil, natural gas, and electricity are recorded when title passes to the customer, net of royalties, discounts and allowances, as applicable. Revenues from crude oil and natural gas production from properties in which the Company has an interest with other producers are recognized on the basis of the Company's net working interest (entitlement method). Shipping and Handling Costs Shipping and handling costs, which consist primarily of natural gas transportation costs, are included in both "Operating costs - oil and gas production" and "Operating costs -electricity generation." Natural gas transportation costs categories were $1.2 million, $1.6 million and $1.4 million for 2001, 2000 and 1999, respectively. 29

BERRY PETROLEUM COMPANY Notes to the Financial Statements 2. Summary of Significant Accounting Policies (cont'd) Stock-Based Compensation As allowed in SFAS No. 123, "Accounting for Stock-Based Compensation", the Company continues to apply Accounting Principles Board Opinion (APB) No. 25, "Accounting for Stock Issued to Employees", and related interpretations in recording compensation related to its plans. The supplemental disclosure requirements of SFAS No. 123 and further information related to the Company's stock option plans are presented in Note 11 to the Company's financial statements. Income Taxes Income taxes are provided based on the liability method of accounting. The provision for income taxes is based on pre-tax financial accounting income. Deferred tax assets and liabilities are recognized for the future expected tax consequences of temporary differences between income tax and financial reporting, and principally relate to differences in the tax basis of assets and liabilities and their reported amounts using enacted tax rates in effect for the year in which differences are expected to reverse. If it is more likely than not that some portion or all of a deferred tax asset will not be realized, a valuation allowance is recognized. Net Income Per Share Basic net income per share is computed by dividing income available to common shareholders (the numerator) by the weighted average number of common shares outstanding (the denominator). The computation of diluted net income per share is similar to the computation of basic net income per share except that the denominator is increased to include the dilutive effect of the additional common shares that would have been outstanding if all convertible securities had been converted to common shares during the period. Recent Accounting Developments In July 2001, the Financial Accounting Standards Boards (FASB) issued SFAS No. 141, "Business Combinations," which supersedes Accounting Principles Board Opinion (APB) No. 16, "Business Combinations." This Statement requires that all business combinations be accounted for by the purchase method, establishes specific criteria for the recognition of intangible assets separately from goodwill and requires unallocated negative goodwill to be written off immediately as an extraordinary gain. The provisions of the Statement apply to business combinations initiated after June 30, 2001. For business combinations accounted for using the purchase method before July 1, 2001, the provisions of this Statement will be effective in the first quarter of 2002. The Company anticipates that the impact of this new standard will have an immaterial impact on the financial statements taken as a whole. In July 2001, the FASB issued SFAS No. 142, "Goodwill and Other Intangible Assets," which supersedes the APB Opinion No. 17, "Intangible Assets." This Statement addresses the accounting and reporting of goodwill and other intangible assets subsequent to their acquisition. The Statement also provides specific guidance on testing goodwill and intangible assets for impairment. SFAS No. 142 provides that (i) goodwill and indefinite-lived intangible assets will no longer be amortized, (ii) impairment will be measured using various valuation techniques based on discounted cash flows, (iii) goodwill will be tested for impairment at least annually at the reporting unit level, (iv) intangible assets deemed to have an indefinite life will be tested for impairment at least annually and (v) intangible assets with finite lives will be amortized over their useful lives. All provisions of this Statement will be effective in the first quarter of 2002. The Company anticipates that the impact of this new standard will have an immaterial impact on the financial statements taken as a whole. In August 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement Obligations," which addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. This Statement requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The associated asset 30

BERRY PETROLEUM COMPANY Notes to the Financial Statements 2. Summary of Significant Accounting Policies (cont'd) retirement costs are capitalized as part of the carrying amount of the long-lived asset. All provisions of this Statement will be effective at the beginning of fiscal 2003. The Company is in the process of determining the impact of this standard on the Company's financial results when effective. In October 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." This Statement supersedes SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of" and amends APB No. 30, "Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions." This Statement requires that long-lived assets that are to be disposed of by sale be measured at the lower of book value or fair value less costs to sell. SFAS No. 144 retains the fundamental provisions of SFAS 121 for (a) recognition and measurement of the impairment of long-lived assets to be held and used and (b) measurement of long-lived assets to be disposed of by sale. This Statement also retains APB No. 30's requirement that companies report discontinued operations separately from continuing operations. All provisions of this Statement will be effective in the first quarter of 2002. The Company anticipates that the impact of this new standard will have an immaterial impact on the financial statements taken as a whole. Reclassifications Certain reclassifications have been made to the 2000 and 1999 financial statements to conform with the 2001 presentation. 3. Fair Value of Financial Instruments The carrying amounts of cash and short-term investments are not materially different from their fair values because of the short maturity of those instruments. Cash equivalents consist principally of commercial paper investments. Cash equivalents of $6.4 million and $2.3 million at December 31, 2001 and 2000, respectively, are stated at cost, which approximates market. The Company's short-term investments available for sale at December 31, 2001 and 2000 consist of a United States treasury note that matures in less than one year. The carrying value of the Company's long-term debt is assumed to approximate its fair value since it is carried at current interest rates. For the three years ended December 31, 2001, realized and unrealized gains and losses were insignificant to the financial statements. A United States treasury note with a market value of $.6 million is pledged as collateral to the California State Lands Commission as a performance bond on the Company's Montalvo properties. In 2001, the Company established an oil price hedge on 3,000 Bbl/day for a one-year period beginning on June 1; and a natural gas price hedge on 5,000 Mmbtu/day for a three-year period beginning on August 1. Both of these hedges were with Enron as the counterparty. On December 10, 2001, after Enron filed for bankruptcy, the Company elected to terminate all contracts with Enron and agreed with them as to the value of the contracts as of termination. Based on the agreed value, the Company recorded a liability of $1.3 million which will be remitted upon the approval by the Enron bankruptcy judge. To protect the Company's revenues from potential price declines, the Company entered into bracketed zero cost collar hedge contracts with California refiners covering 3,000 BPD to 6,500 BPD of its crude oil production during 2000 and 1999, with the most recent contracts expiring on December 31, 2000. The Company recorded losses of $7.1 million and $2.6 million in 2000 and 1999, respectively, which were reported in "Sales of oil and gas" in the Company's financial statements. 31

BERRY PETROLEUM COMPANY Notes to the Financial Statements 3. Fair Value of Financial Instruments (cont'd) In December 2000, the Company entered into a series of derivative contracts to reduce exposure to unfavorable changes in natural gas prices. These contracts limited the price the Company paid for 4,500 Mmbtu/day of natural gas for the three-month period ending March 31, 2001. In the first quarter of 2001, the Company earned $1.4 million pre-tax from these hedges which was recorded as a reduction to "Operating costs - electricity generation". 4. Concentration of Credit Risks The Company sells oil, gas and natural gas liquids to pipelines, refineries and major oil companies and electricity to major utility companies. Credit is extended based on an evaluation of the customer's financial condition and historical payment record. Primarily due to the Company's ability to deliver significant volumes of crude oil over a multi-year period, the Company was able to secure a three-year sales agreement, beginning in April 2000, with a major California refiner whereby the Company sells in excess of 80% of its production under a negotiated pricing mechanism. The agreement is based on a monthly determination of the highest price from any of (1) local field posted price plus a fixed bonus, (2) WTI minus a fixed differential or (3) a fixed percentage of WTI. In addition to providing a premium above field postings, the agreement effectively eliminates the Company's exposure to the risk of widening WTI-heavy crude price differentials. For the three years ended December 31, 2001, the Company has experienced no credit losses on the sale of oil, gas and natural gas liquids. However, the Company did experience a loss on its electricity sales in 2001. The Company assigned all of its rights, title and interest in its $12.1 million past due receivables from Pacific Gas and Electric Company to an unrelated party for $9.3 million, resulting in a pre-tax loss of $2.8 million. In addition, at December 31, 2001, the Company was owed $13.5 million from Southern California Edison Company (SCE) for past due electricity sales. The Company wrote off $3.6 million of this balance in March 2001. However, see Note 14. The Company places its temporary cash investments with high quality financial institutions and limits the amount of credit exposure to any one financial institution. For the three years ended December 31, 2001, the Company has not incurred losses related to these investments. The following summarizes the accounts receivable balances at December 31, 2001 and 2000 and sales activity with significant customers for each of the years ended December 31, 2001, 2000 and 1999 (in thousands). The Company does not believe that the loss of any one customer would impact the marketability of its oil, gas, natural gas liquids or electricity sold.

At December 31, 2001 and 2000, the Company had $25 and $25 million, respectively, outstanding under the Agreement. In addition to the $25 million in borrowings under the Agreement, the Company has $6.7 million of outstanding Letters of Credit and the remaining credit available under the Agreement is therefore, $118.3 million at December 31, 2001. The maximum amount available is subject to an annual redetermination of the borrowing base in accordance with the lender's customary procedures and practices. Both the Company and the banks have bilateral rights to one additional redetermination each year. The revolving period is scheduled to terminate on January 21, 2004. Interest on amounts borrowed is charged at the lead bank's base rate or at London Interbank Offered Rates (LIBOR) plus 75 to 150 basis points, depending on the ratio of outstanding credit to the borrowing base. The weighted average interest rate on outstanding borrowings at December 31, 2001 was 4.92%. The Company pays a commitment fee of 25 to 35 basis points on the available unused portion of the commitment. The credit agreement contains other restrictive covenants as defined in the Agreement. 7. Shareholders' Equity Shares of Class A Common Stock (Common Stock) and Class B Stock, referred to collectively as the "Capital Stock," are each entitled to one vote and 95% of one vote, respectively. Each share of Class B Stock is entitled to a $1.00 per share preference in the event of liquidation or dissolution. Further, each share of Class B Stock is convertible into one share of Common Stock at the option of the holder. 34

BERRY PETROLEUM COMPANY Notes to the Financial Statements 7. Shareholders' Equity (cont'd) In November 1999, the Company adopted a Shareholder Rights Agreement and declared a dividend distribution of one Right for each outstanding share of Capital Stock on December 8, 1999. Each Right, when exercisable, entitles the holder to purchase one one-hundredth of a share of a Series B Junior Participating Preferred Stock, or in certain cases other securities, for $38.00. The exercise price and number of shares issuable are subject to adjustment to prevent dilution. The Rights would become exercisable, unless earlier redeemed by the Company, 10 days following a public announcement that a person or group has acquired, or obtained the right to acquire, 20% or more of the outstanding shares of Common Stock or, 10 business days following the commencement of a tender or exchange offer for such outstanding shares which would result in such person or group acquiring 20% or more of the outstanding shares of Common Stock, either event occurring without the prior consent of the Company. The Rights will expire on December 8, 2009 or may be redeemed by the Company at $.01 per Right prior to that date unless they have theretofore become exercisable. The Rights do not have voting or dividend rights, and until they become exercisable, have no diluting effect on the earnings of the Company. A total of 250,000 shares of the Company's Preferred Stock has been designated Series B Junior Participating Preferred Stock and reserved for issuance upon exercise of the Rights. This Shareholder Rights Agreement replaced the Shareholder Rights Agreement approved in December 1989 which expired on December 8, 1999. In conjunction with the acquisition of the Tannehill assets in 1996, the Company issued a Warrant Certificate to the beneficial owners of Tannehill Oil Company. This Warrant authorizes the purchase of 100,000 shares of Berry Petroleum Company Class A Common Stock until November 8, 2003 at $14.06 per share. All the warrants are currently outstanding and the underlying shares will not be registered under the Securities Act of 1933. In August 2001, the Board of Directors authorized the Company to repurchase $20 million of Common Stock in the open market. As of December 31, 2001, the Company had repurchased 308,075 shares for approximately $5.1 million. All shares repurchased were retired. The Company issued 6,529, 21,325 and 2,745 shares in 2001, 2000 and 1999, respectively, through its stock option plan. At December 31, 2001, dividends declared on 4,000,894 shares of certain Common Stock are restricted, whereby 37.5% of the dividends declared on these shares are paid by the Company to the surviving member of a group of individuals, the B Group, as long as this remaining member shall live. 8.

BERRY PETROLEUM COMPANY Notes to the Financial Statements 9. Commitment Corporate Offices Operating Lease The Company relocated its corporate offices in March 2002. The lease term is from January 1, 2002 through October 31, 2006 and requires minimum rental payments as follows: Year ending December 31, 2002 $ 366,920 2003 440,305 2004 440,305 2005 440,305 2006 366,920 --------- Total $2,054,755 ========= 10. Contingencies The Company has accrued environmental liabilities for all sites, including sites in which governmental agencies have designated the Company as a potentially responsible party (PRP), where it is probable that a loss will be incurred and the minimum cost or amount of loss can be reasonably estimated. However, because of the uncertainties associated with environmental assessment and remediation activities, future expense to remediate the currently identified sites, and sites which could be identified in the future for cleanup, could be higher than the liability currently accrued. Amounts currently accrued are not significant to the consolidated financial position of the Company and Management believes, based upon current site assessments, that the ultimate resolution of these matters will not require substantial additional accruals. The Company is involved in various other lawsuits, claims and inquiries, most of which are routine to the nature of its business. In the opinion of Management, the resolution of these matters will not materially affect the Company. 11. Stock Option Plan On December 2, 1994, the Board of Directors of the Company adopted the Berry Petroleum Company 1994 Stock Option Plan which was restated and amended in December 1997 (the 1994 Plan) and approved by the shareholders in May 1998. The 1994 Plan provides for the granting of stock options to purchase up to an aggregate of 2,000,000 shares of Common Stock. All options, with the exception of the formula grants to non-employee Directors, will be granted at the discretion of the Compensation Committee of the Board of Directors. The term of each option may not exceed ten years from the date the option is granted. On December 7, 2001 and December 1, 2000, 199,500 and 262,000 options, respectively, were issued to certain key employees at an exercise price of $16.30 and $15.6875 per share, respectively, which was the closing market price of the Company's Class A Common Stock on the New York Stock Exchange on those dates. The options vest 25% per year for four years. No employee options were issued in 1999. The 1994 Plan also allows for option grants to the Board of Directors under a formula plan whereby all non-employee Directors are eligible to receive 5,000 options annually on December 2 at the fair value on the date of grant. The options granted to the non-employee Directors vest immediately. Through the 1994 Plan, 40,000, 40,000 and 40,000 options, respectively, were issued on December 2, 2001, 2000 and 1999, (5,000 options to each of the non-employee Directors each year) at an exercise price of $15.45, $15.6875 and $14.0625 per share, respectively. 37

BERRY PETROLEUM COMPANY Notes to the Financial Statements 11. Stock Option Plan (cont'd) The Company applies APB No. 25 and related interpretations in accounting for its stock option plan. The options issued per the 1994 Plan were issued at market price. Compensation recognized related to the 1994 Plan was $0 million in 2001, $.3 million in 2000 and $0 in 1999. Under SFAS No. 123, compensation cost would be recognized for the fair value of the employee's option rights. The fair value of each option grant was estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions: 2001 2000 1999 Yield 2.72% 2.77% 2.75% Expected option life - years 7.5 4.5 4.0 Volatility 38.71% 36.53% 34.24% Risk-free interest rate 4.65% 4.85% 6.33% Had compensation cost for the 1994 Plan been based upon the fair value at the grant dates for awards under this plan consistent with the method of SFAS No. 123, the Company's net income and earnings per share would have been reduced to the pro forma amounts indicated below (in thousands, except per share data): 2001 2000 1999 Net income as reported $21,938 $37,183 $18,006 Pro forma 21,197 36,581 17,343 Net income per share as reported 1.00 1.69 .82 Pro forma .99 1.66 .79 The following is a summary of stock-based compensation activity for the years 2001, 2000 and 1999. 2001 2000 1999 Options Options Options Balance outstanding, January 1 1,407,837 1,220,630 1,227,630 Granted 239,500 302,000 40,000 Exercised (65,125) (114,793) (22,000) Canceled/expired (107,250) - (25,000) --------- --------- --------- Balance outstanding, December 31 1,474,962 1,407,837 1,220,630 ========= ========= ========= Balance exercisable at December 31 1,010,712 872,587 697,630 ========= ========= ========= Available for future grant 232,550 364,800 666,800 ========= ========= ========= Exercise price-range $ 14.40 $ 16.4375 $ 14.125 to 16.96 to 19.00 to 14.25 Weighted average remaining contractual life (years) 7 8 8 Weighted average fair value per option granted during the $ 5.87 $ 4.62 $ 5.14 year 38

Retirement Plan The Company sponsors a defined contribution retirement or thrift plan (401(k) Plan) to assist all employees in providing for retirement or other future financial needs. Employee contributions (up to 6% of earnings) are matched by the Company dollar for dollar. Effective November 1, 1992, the 401(k) Plan was modified to provide for increased Company matching of employee contributions whereby the monthly Company matching contributions will range from 6% to 9% of eligible participating employee earnings, if certain financial targets are achieved. The Company's contributions to the 401(k) Plan were $.4 million in 2001, $.5 million in 2000 and $.3 million in 1999. 13.

BERRY PETROLEUM COMPANY Supplemental Information About Oil & Gas Producing Activities (Unaudited) The following estimates of proved oil and gas reserves, both developed and undeveloped, represent interests owned by the Company located solely within the United States. Proved reserves represent estimated quantities of crude 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. Proved developed oil and gas reserves are the quantities expected to be recovered through existing wells with existing equipment and operating methods. Proved undeveloped oil and gas reserves are reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells for which relatively major expenditures are required for completion. Disclosures of oil and gas reserves which follow are based on estimates prepared by independent engineering consultants as of December 31, 2001, 2000 and 1999. Such estimates are subject to numerous uncertainties inherent in the estimation of quantities of proved reserves and in the projection of future rates of production and the timing of development expenditures. These estimates do not include probable or possible reserves. The information provided does not represent Management's estimate of the Company's expected future cash flows or value of proved oil and gas reserves. Changes in estimated reserve quantities The net interest in estimated quantities of proved developed and undeveloped reserves of crude oil and natural gas at December 31, 2001, 2000 and 1999, and changes in such quantities during each of the years then ended were as follows (in thousands): 2001 2000 1999 Oil Gas Oil Gas Oil Gas Mbbls Mmcf Mbbls Mmcf Mbbls Mmcf Proved developed and undeveloped reserves: Beginning of year 106,664 4,184 111,888 3,920 91,933 4,060 Revision of previous estimates 33 153 (1,284) 463 3,126 40 Production (4,996) (288) (5,434) (199) (5,060) (180) Purchase of reserves in place - 2,877 1,494 - 21,889 - ------- ----- ------- ----- ------- ----- End of year 101,701 6,926 106,664 4,184 111,888 3,920 ======= ===== ======= ===== ======= ===== Proved developed reserves: Beginning of year 81,132 1,635 86,717 1,371 83,532 1,604 ======= ===== ======= ===== ======= ===== End of year 79,317 3,518 81,132 1,635 86,717 1,371 ======= ===== ======= ===== ======= ===== 40

  DESCRIPTION OF THE SHORT-TERM CASH INCENTIVE PLAN (BONUS)

     Annual cash incentive awards, which are designed to
provide short-term performance incentives, are made to
executives and other employees to recognize and reward
corporate and individual performance. The plan in effect
provides an annual incentive fund of up to 3.5% of the
Company's annual net income, with certain adjustments, for
executives and other employees involved in decision-making
roles which effect the Company's growth and profitability
goals.

	Annually, Management and the Board will set specific
targets to be achieved which will determine the cash payout
as a whole and then to each eligible employee based on a
formula. There shall be specific targets established for
each of the following: production volume, reserve
replacement, and non-steam operating cost.  The Board
retains the flexibility to adjust various items to assure
compliance with the intent of the plans.  All annual cash

Gentlemen:

     In connection with the Annual Report on Form 10-K for the
fiscal year ended December 31, 2001, (the Annual Report) of Berry
Petroleum Company (the Company), we hereby consent to (i) the use
of and reference to our report dated February 25, 2002, entitled
"Appraisal Report, as of December 31, 2001, on Certain Property
Interests owned by Berry Petroleum Company," which pertains to
interests of the Company in certain oil and gas properties
located in California, Louisiana, Nevada, Oklahoma, Texas, and
Wyoming; our report dated February 26, 2001, entitled "Appraisal
Report, as of December 31, 2000, on Certain Property Interests
owned by Berry Petroleum Company," which pertains to interests of
the Company in certain oil and gas properties located in
California, Louisiana, Nevada, Oklahoma, Texas, and Wyoming; our
report dated February 16, 2000, entitled "Appraisal Report, as of
December 31, 1999, on Certain Property Interests owned by Berry
Petroleum Company," which pertains to interests of the Company in
certain oil and gas properties located in California, Louisiana,
Nevada, Oklahoma, Texas, and Wyoming (collectively referred to as
the "Report"), under the caption "Oil and Gas Reserves" in items
1 and 2 of the Annual Report and under the caption "Supplemental

in item 8 of the Annual Report; and (ii) the use of and reference
to the name DeGolyer and MacNaughton as the independent petroleum
engineering firm that prepared the Reports under such items;
provided, however, that since the cash-flow calculations in the
Annual Report include estimated income taxes not included in the
Reports, we are unable to verify the accuracy of the cash-flow
values in the Annual Report.

                              Very truly yours,


                              DeGOLYER and MacNAUGHTON

         UNDERTAKING FOR FORM S-8 REGISTRATION STATEMENT

     For purposes of complying with the amendments to the rules
governing Form S-8 (effective July 13, 1990) under the Securities
Act of 1933, the Company hereby undertakes as follows, which
undertaking shall be incorporated by reference into the Company's
Registration Statements on Form S-8 (No. 333-62799, 333-62871 and
333-62873):

     Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to director, officers and
controlling persons of the Company pursuant to the foregoing
provisions, or otherwise, the Company has been advised that in
the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the
Securities Act of 1933 and is, therefore, unenforceable.  In the
event that a claim for indemnification against such liabilities
(other than the payment by the Company of expenses incurred or
paid by a director, officer or controlling person of the Company
in the successful defense of any action, suit or proceeding is
asserted by such director, officer or controlling person in
connection with the securities being registered, the Company
will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such
indemnification is against public policy as expressed in the Act
and will be governed by the final adjudication of such issue.
