ITEM 1. BUSINESS This annual report on Form 10-K is a combined report being filed by two separate Registrants: American States Water Company (hereinafter "AWR") and Southern California Water Company (hereinafter "SCW"). References in this report to "Registrant" are to AWR and SCW, collectively, unless otherwise specified. SCW makes no representations as to the information contained in this report relating to AWR and its subsidiaries, other than SCW. GENERAL AWR, incorporated in 1998, is engaged in the business of holding, for investment, the stock primarily of utility companies. AWR's principal investment is the stock of SCW. SCW is a California public utility company engaged 31, 2001, compared with 11,063 customers at December 31, 2000. ASUS has approximately 90,000 accounts under contract. COMPETITION The businesses of SCW and CCWC are substantially free from direct and indirect competition with other public utilities, municipalities and other public agencies. AWR's other subsidiary, ASUS, actively competes with other investor-owned utilities, other third party providers of water and wastewater services, and governmental entities on the basis of price and quality of service. EMPLOYEE RELATIONS SCW had 481 employees as of December 31, 2001 as compared to 489 at December 31, 2000. Seventeen positions in SCW's Bear Valley Electric customer service area are covered by a collective bargaining agreement, which expires in 2002, with the International Brotherhood of Electrical Workers.

ITEM 2 - PROPERTIES FRANCHISES AND CONDEMNATION OF PROPERTIES SCW holds certificates of public convenience and necessity granted by the CPUC in each of the ratemaking districts it serves. CCWC holds certificates of public convenience and necessity granted by the ACC for the areas in which it serves. CCWC's certificates and similar rights are subject to alteration, suspension or repeal by the respective governmental authorities having jurisdiction. Both SCW and CCWC hold franchises, easements and rights of way pursuant to the terms of agreements that must periodically be renewed. These agreements are also subject to suspension or termination in certain circumstances if SCW or CCWC, as applicable, violate the terms of these agreements. The laws of the State of California and the State of Arizona provide for the acquisition of public utility property by governmental agencies through the power of eminent domain, also known as condemnation. Registrant has not been, within the last three years, involved in activities related to the condemnation of any of its water customer service areas or in its Bear Valley Electric customer service area. ELECTRIC PROPERTIES SCW's electric properties are all located in the Big Bear area of San Bernardino County in California. As of December 31, 2001, SCW operated 28.7 miles of overhead 34.5 kv transmission lines, 0.6 miles of underground 34.5 kv transmission lines, 173.6 miles of 4.16 kv or 2.4 kv distribution lines, 42.3 miles of underground cable and 14 sub-stations. Neither AWR nor any of its subsidiaries own electric generating plants. OFFICE BUILDINGS Registrant's general offices are housed in a single-story office building located in San Dimas, California. The land and the building are owned by SCW. SCW also owns and occupies certain facilities housing regional, district and customer service offices while other such facilities are housed in leased premises. CCWC owns its primary office space. 1

WATER PROPERTIES As of December 31, 2001, SCW's physical properties consisted of water transmission and distribution systems which included 2,719 miles of pipeline together with services, meters and fire hydrants and approximately 430 parcels of land, generally less than 1 acre each, on which are located wells, pumping plants, reservoirs and other water utility facilities, including five surface water treatment plants. As of December 31, 2001, SCW owned 280 wells. Certain wells have been removed from service due to water quality problems. For further information, see the section entitled "Environmental Matters" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. All wells are equipped with pumps with an aggregate capacity of approximately 203 million gallons per day. SCW has 57 connections to the water distribution facilities of the Metropolitan Water District of Southern California (MWD) and other municipal water agencies. SCW's storage reservoirs and tanks have an aggregate capacity of approximately 103 million gallons. SCW owns no dams in its customer service areas.

MORTGAGE AND OTHER LIENS As of December 31, 2001, SCW had no mortgage debt outstanding, and its properties were free of any encumbrances or liens securing indebtedness. As of December 31, 2001, substantially all of the utility plant of CCWC was pledged to secure its Industrial Development Authority Bonds. The Bond Agreement, among other things, restricts CCWC's ability to incur debt and make liens, sell, lease or dispose of assets, or merge with another corporation, and pay dividends. As of December 31, 2001, neither AWR nor ASUS had any mortgage debt or liens securing indebtedness outstanding. 2

ITEM 3 - LEGAL PROCEEDINGS WATER QUALITY-RELATED LITIGATION SCW is a defendant in twenty lawsuits involving claims pertaining to water quality. Seventeen of the lawsuits involve customer service areas located in Los Angeles County in the southern portion of the State of California that have been filed in Los Angeles Superior Court: Adler v. Southern California Water Company, et al., Case No. BC169892, Santamaria v. Suburban Water Systems, et al., Case No. CIV180894, Georgianna v. Dominguez et al. v. Southern California Water Company, et al., Case No. G021657, Anderson, et al. v. Suburban Water Company, et al., Case No. KC028524, Abarca, et al. v. City of Pomona, et al., Case No. K027795, Celi, et al. v. San Gabriel Valley Water Company, Case No. GC020622, Boswell et al. v. Suburban Water Systems, et al., Case No. KC027318, Demciuc et al. v. Suburban Water Systems, et al., Case No. C028732, Adejare, et al. v. Southern California Water Company, Case No. KC031096, Almelia Brooks, et al. v. Suburban Water System, et al., Case No. KC032915, Lori Alexander, et al. v. Suburban Water Systems, et al., Case No. KC031130, David Arnold, et al. v. City of Pomona, et al., Case No. KC034636, Gilda Ambrose-Dubre, et al. v. City of Pomona, et al., Case No. KC032906, Melissa Garrity Alvarado, et al. v. Suburban Water Systems et al., Case No. KC034953 , Charles Alexander, et al. v. City of Pomona, et al., Case No KC035526, Criner, et al. v. San Gabriel Valley Water Company, et al., Case No. GC021658, and Donerson, et al. v. City of Pomona, et al., Case No. KC035987. The lawsuits filed in Los Angeles County Superior Court are based on the allegations that SCW and the other defendants have provided and continue to provide plaintiffs with contaminated water from wells located in an area of the San Gabriel Valley that has been designated a federal superfund site, that the maintenance of this contaminated well water has resulted in contamination of the soil, subsurface soil and surrounding air with trichloroethylene ("TCE"), perchloroethene ("PCE"), carbon tetrachloride and other solvents and that plaintiffs have been injured and their property damaged as a result. Three of the lawsuits involve a customer service area located in Sacramento County in northern California that have been filed in Sacramento County Superior Court: Nathaniel Allen, Jr. v. Aerojet-General Corporation, et al., Case No. 97AS06295, Daphne Adams, et al. v. Aerojet-General Corporation, et al., Case No. 98AS01025, and Wallace Andrew Pennington et al. v. Aerojet-General Corporation, et al., Case No. 00AS02622. The lawsuits filed in Sacramento County Superior Court are based on the allegations that SCW and other defendants have delivered water to plaintiffs that is contaminated with a number of chemicals, including, TCE, PCE, carbon tetrachloride, perchlorate, Freon-113, hexavalent chromium and other unnamed chemicals and that plaintiffs have been injured and their property damaged as a result. On September 1, 1999, the Court of Appeals in San Francisco held that the CPUC had preemptive jurisdiction over regulated public utilities with respect to water quality matters and ordered dismissal of a series of these lawsuits. On October 11, 1999, one group of plaintiffs appealed this decision to the California Supreme Court. On February 4, 2002, the California Supreme Court concluded that (i) the CPUC had preemptive jurisdiction over claims seeking injunctive relief and claims based on the theory that a public utility regulated by the CPUC provided unsafe drinking water even though it had complied with federal and state drinking water standards, but (ii) the CPUC did not have preemptive jurisdiction over damage claims based on allegations of violations of federal and state drinking water standards by public utilities regulated by the CPUC. As a result, damage claims based on allegations of violations of federal and state drinking water standards may proceed while the other claims must be dismissed. In light of the breadth of plaintiffs' claims, the lack of factual information regarding plaintiff's claims and injuries, if any, the impact of the California Supreme Court decision on plaintiffs' claims and the fact that no discovery has yet been completed, SCW is unable at this time to determine what, if any, potential liability it may have with respect to these claims. Based upon the information currently available to it, Registrant believes that these claims are without merit and intends to vigorously defend these claims. SCW is subject to self-insured retention provisions in its applicable insurance policies and has either expensed the self-insured amounts or has reserved against payment of these amounts as appropriate. SCW's various insurance carriers have, to date, provided reimbursement for costs incurred above the self-insured amounts for defense against these lawsuits, subject to a reservation of rights. ORDER INSTITUTING INVESTIGATION (OII) In March 1998, the CPUC issued an OII to regulated water utilities in the state of California, including SCW. The purpose of the OII was to determine whether existing standards and policies regarding drinking water quality adequately protect the public health and whether those standards and policies were being uniformly complied with by those water utilities. On November 2, 2000, a final decision from the CPUC concluded that the Commission has the jurisdiction to regulate the service of water utilities with respect to the health and safety of that service; that the California 3

Department of Health Services' requirements governing drinking water quality adequately protect the public health and safety; and that regulated water utilities, including SCW, have satisfactorily complied with past and present drinking water quality requirements. The CPUC had previously authorized establishment of memorandum accounts to capture expenses related to the OII. Under the memorandum account procedure, SCW may recover litigation costs from ratepayers to the extent authorized by the CPUC. The CPUC has not yet authorized SCW to recover any of its litigation costs. As of December 31, 2001, SCW had recorded a net of $888,700 in this memorandum account. Management believes that these expenses will be fully recovered but is unable to predict when, or if, the CPUC will authorize recovery of all or any of the costs. OTHER WATER QUALITY LITIGATION On October 25, 1999, SCW filed a lawsuit against the California Central Valley Regional Water Quality Control Board (CRWQCB) alleging that the CRWQCB has willfully allowed portions of the Sacramento County Groundwater Basin to be injected with chemical pollution that is destroying the underground water supply in SCW's Rancho Cordova customer service area. Management cannot predict the likely outcome of this proceeding. In a separate case, also filed on October 25, 1999, SCW sued Aerojet-General Corporation (Aerojet) for causing the contamination of the Sacramento County Groundwater Basin. On March 22, 2000, Aerojet filed a cross complaint against SCW for negligence and constituting a public nuisance. Registrant is unable to determine at this time what, if any, potential liability it may have with respect to the cross complaint, but intends to vigorously defend itself against these allegations. Management cannot predict the likely outcome of these proceedings. The CPUC has authorized memorandum accounts to allow for recovery of costs incurred by SCW in prosecuting the suits filed against CRWQCB and Aerojet from customers, less any recovery from the defendants or others. As of December 31, 2001, approximately $6,640,000 has been recorded in the memorandum accounts. The CPUC has authorized SCW to increase rates, effective April 28, 2001, for recovery over a six-year period of approximately $1,800,000, in expenses that were incurred on or before August 31, 2000. SCW will continue to file additional Advice Letters to recover the remaining costs. Management believes these costs are recoverable but cannot give assurance that the CPUC will ultimately allow recovery of all or any of the remaining costs through rates. On April 25, 2001, Registrant filed a lawsuit against all the potentially responsible parties, who stored, transported and dispensed gasoline containing methyl tertiary butyl ether (MTBE) in underground storage tanks, pipelines or other related infrastructure. MTBE contaminated water existing in areas of the basin from which SCW has pumped water through its Charnock Well Field. As a result, SCW ceased operation of its Charnock Well Field in October 1996. Registrant has reached an agreement in this matter that assigns the prosecution of litigation against the potentially responsible parties to the City of Santa Monica, California (Santa Monica). As part of the agreement and in exchange for an assignment payment, Santa Monica will prosecute the case against the potentially responsible parties. Registrant expects that Santa Monica will sign the agreement by the end of the first quarter of 2002. ELECTRIC SERVICE LITIGATION SCW has been, in conjunction with the Southern California Edison (Edison) unit of Edison International, planning to upgrade transmission facilities to 115kv (the 115kv Project) in order to meet increased energy and demand requirements for SCW's Bear Valley Electric Service area. On December 27, 2000, SCW filed a lawsuit against Edison for declaratory relief and seeking damages for breach of contract as a result of delays in the 115kv Project. Subsequently Edison filed a cross-complaint against SCW for breach of contract, anticipatory breach, and quantum meruit. Registrant has discussed various settlement options with Edison regarding this matter. However, management cannot predict the likely outcome of this matter. OTHER LITIGATION Registrant is also subject to ordinary routine litigation incidental to its business. Other than as disclosed above, no legal proceedings are pending, except such incidental litigation, to which Registrant is a party or of which any of its properties is the subject, which are believed to be material. For further information, see Note 8 to the "Notes to Financial Statements in Part II, Item 8 in Financial Statements and Supplementary Data. 4

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATION Unless specifically noted, the following discussion and analysis provides information on AWR's consolidated operations and assets. For the twelve months ended December 31, 2001, there is generally no material difference between the consolidated operations and assets of AWR and the operations and assets of SCW. However, where necessary, the following discussion and analysis includes references specific to AWR's other subsidiaries - CCWC and ASUS. FORWARD-LOOKING INFORMATION Certain matters discussed in this report (including the documents incorporated herein by reference) are forward-looking statements intended to qualify for the "safe harbor" from liability established by the Private Securities Litigation Reform Act of 1995. These forward-looking statements can generally be identified as such because the context of the 6

statement will include words such as Registrant "believes," "anticipates," "expects" or words of similar import. Similarly, statements that describe Registrant's future plans, objectives, estimates or goals are also forward-looking statements. Such statements address future events and conditions concerning capital expenditures, earnings, litigation, rates, water quality and other regulatory matters, adequacy of water supplies, the California energy crisis, liquidity and capital resources, opportunities related to operations and maintenance of water systems owned by governmental entities and other utilities and providing related services, and accounting matters. Actual results in each case could differ materially from those currently anticipated in such statements, by reason of factors such as utility restructuring, including ongoing local, state and federal activities; future economic conditions, including changes in customer demand and changes in water and energy supply cost; future climatic conditions; and legislative, regulatory and other circumstances affecting anticipated revenues and costs. RESULTS OF OPERATIONS YEARS ENDED DECEMBER 31, 2001 AND 2000 Basic earnings per common share in 2001 increased by 5.2% to $2.02 per share as compared to $1.92 per share for the comparable period of 2000. The increases in the recorded results primarily reflect the impact of various rate increases authorized by the Public Utilities Commission of the State of California (CPUC) for SCW, additional revenues generated by CCWC since the acquisition in October 2000, improvement in operating margins and, to some extent Registrant's Cash Preservation Plan (CPP) discussed below. For the year ended December 31, 2001, fully diluted earnings were $2.00 per share as compared to $1.91 per share for the comparable period of 2000. For further information, see the section entitled "Liquidity and Capital Resources" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. Water operating revenues increased by 7.5% in 2001 to $181.5 million from the $168.8 million reported in 2000 due to increases in water rates authorized by the CPUC, and an additional $6.3 million in revenues generated by CCWC. New rates, representing an annualized increase of $3.1 million, in the customer service areas that comprise SCW's Region I were implemented during 2001. Rate increases, representing an annualized increase of $2.9 million, for SCW's Region II and rate increases for SCW's Region III, representing an annualized increase of $3.9 million, were also implemented at various times during 2001. The additional revenues generated by rate increases were partially offset by a 3.4% reduction in water sales throughout most of SCW's customer service areas in 2001 due to relatively mild weather. For further information, see the section entitled "Regulatory Matters" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. Electric revenues increased by 6.3% to $15.3 million in 2001 as compared to $14.4 million in 2000. The increases reflected a rate increase of 12.5% effective May 24, 2001 and an additional 14.8% increase effective August 23, 2001 authorized by the CPUC to recover previously under-collected energy costs. The increases were partially offset by a decrease of 5.3% in kilowatt-hour consumption, primarily due to heavier winter snows experienced in SCW's service area in 2001, which decreased the use of snow making machines at ski resorts in the area. For further information, see the sections entitled "Regulatory Matters" and "Electric Energy Situation in California" in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. Purchased water costs in 2001 decreased by 9.6% to $37.6 million as compared to $41.6 million in 2000 reflecting a decrease in purchased water volume resulting from both lower sales and less purchased water in Registrant's supply mix, as well as refunds received from Registrant's wholesale water suppliers during 2001 of approximately $770,000. There was no similar refund in 2000. Purchased water expense at CCWC was approximately $497,000. Costs of power purchased for pumping increased by 27.7% to $9.6 million in 2001 as compared to $7.5 million recorded in 2000, due to the rate increases implemented by SCW's energy suppliers pursuant to CPUC decisions, and increased pumped water in SCW's supply mix. In 2001, the CPUC approved SCW's Advice Letters to increase revenues by approximately $1.4 million annually to recover the costs of purchased power for its water ratemaking districts. For further information, see the sections entitled "Regulatory Matters" and "Electric Energy Situation in California" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. During 2001, CCWC incurred approximately $423,000 in power costs used for pumping. In 2001, SCW's overall water supply mix improved over the mix authorized in rates due to additional well production capability coming on-line during the year. Changes in actual supply mix as compared to that authorized in rates can favorably or unfavorably impact earnings. There is no assurance that the favorable mix can be sustained in future periods since actual results are affected by availability and quality of water, both purchased and produced from 7

SCW's wells. For further information, see the section entitled "Water Supply" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. Costs of power purchased for resale to customers in SCW's Bear Valley Electric division in 2001 increased by 84.1% to $19.7 million from the $10.7 million recorded in 2000 due primarily to significant increases in wholesale market prices for energy in the State of California. The increase was partially offset by a one-time sale of energy on the spot market that resulted in a $644,000 gain in April 2001. The sale of excess energy on the spot market resulted from a one-month overlap of energy purchase agreements. For further information, see the sections entitled "Liquidity and Capital Resources", "Regulatory Matters" and "Electric Energy Situation in California" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. Groundwater production assessments decreased by 9.3% to $6.8 million in 2001 from $7.5 million in 2000. The decrease occurred principally in SCW's San Gabriel and San Dimas customer service areas due to lower administrative assessments levied against production for the water year 2001 as compared with the previous year, and a credit of $440,000 recorded in the fourth quarter of 2001 for the sale of groundwater in the Chino Basin. There was no such sale in 2000. A positive entry for the provision for supply cost balancing accounts reflects recovery of previously under-collected supply costs. Conversely, a negative entry for the provision for supply cost balancing accounts reflects an under-collection of previously incurred supply costs. The negative entries for 2001 primarily reflect untimely-recovery of electric power costs discussed previously. At December 31, 2001, Registrant had a net under-collected position of $25.8 million in both its water and electric balancing accounts primarily due to the increases in energy costs. For further information, see the sections entitled "Accounting for Supply Costs", "Liquidity and Capital Resources", "Regulatory Matters" and "Electric Energy Situation in California" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. Other operating expenses increased by 3.0% in 2001 to $17.2 million as compared with $16.7 million in 2000 due primarily to operating expenses at CCWC, offset by the effects of the CPP at SCW that reduced or deferred a number of expense items. Administrative and general expenses increased by 34.5% to $35.1 million in 2001 from $26.1 million recorded in 2000 reflecting (i) reserves of $7.9 million established for potential non-recovery of electric power costs incurred to serve customers at SCW's Bear Valley Electric customer service area, (ii) increased reserves for self-insured worker's compensation liabilities, and (iii) additional costs from CCWC. The reserves were established to offset future impacts to earnings in the event that SCW was unable to fully recover all of its purchased power costs through rates. For further information, see the sections entitled "Regulatory Matters" and "Electric Energy Situation in California" in Part II, Item 7 in the Management's Discussion and Analysis of Financial Condition and Results of Operation and Note 7 of "Notes to Financial Statements" included in Part II, Item 8 in Financial Statements and Supplementary Data. Depreciation expense in 2001 increased by 17.6% to $18.0 million reflecting, among other things, the effects of recording approximately $40.1 million in net plant additions at SCW during 2000, depreciation on which began in January 2001, and additional depreciation associated with CCWC's plant. In addition, amortization of goodwill, which represents the difference between the purchase price of the common equity of CCWC and CCWC's book equity at the time of closing, began October 2000. Pursuant to FASB No. 142, Goodwill and Other Intangible Assets, amortization of this goodwill, which was $331,073 in 2001, will cease on January 1, 2002. AWR has concluded that this goodwill is not impaired. As compared to 2000, maintenance expense decreased by 16.5% to $8.6 million due primarily to the implementation of Registrant's CPP in April 2001 to control costs and temporarily to limit capital and maintenance expenditures principally to those projects that were believed necessary to meet public safety and health requirements or otherwise provide for continued service pending CPUC approval of rate increases that would permit SCW to begin recovery of power costs incurred during California's energy crisis. The CPP impacted both the electric and water businesses of SCW. Management estimates that the CPP, through deferral of capital expenditures alone, reduced cash expenditures in 2001 by approximately $20 million. The CPP will remain in effect until SCW receives approval to increase electric rates pursuant to the terms of a settlement agreement. For further information, see the sections entitled "Electric Energy Situation in California" and "Regulatory Matters" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. Taxes on income increased slightly by 2.0% to $15.4 million in 2001 as compared to $15.1 million in 2000 due primarily to an approximately 9.1% increase in pre-tax operating income, the effect of which was partially offset by a lower effective tax rate. 8

Property and other tax expense increased by 7.0% in 2001 to $7.6 million reflecting principally increased property taxes due to higher property valuation assessments, and additional property and payroll taxes at CCWC. The loss recorded in other income for 2001 was due principally to the write-off of expenses associated with the termination of the acquisition of Peerless Water Co. The loss also reflects the effects of recording amortization and interest expenses, starting January 2000, on SCW's 500 acre-foot entitlement in the State Water Project (SWP). During the fourth quarter of 2001, SCW signed an agreement with a property developer requiring an assured water supply to complete construction of a development. Under the terms of this Agreement, the developer will reimburse SCW for the costs related to 350 acre-feet of SCW's SWP entitlement. Interest expense increased by 11.3% in 2001 to $15.7 million as compared to $14.1 million recorded in 2000 due to (i) short-term borrowing to fund capital expenditures, (ii) the issuance of $20 million in long-term debt by SCW in January 2001, (iii) the issuance of $50 million in long-term debt by SCW in December 2001, and (iv) the inclusion of long-term debt at Registrant's CCWC unit. YEARS ENDED DECEMBER 31, 2000 AND 1999 Basic earnings per common share in 2000 increased by 7.3% to $1.92 per share as compared to $1.79 per share for the comparable period of 1999. The increase in the recorded results primarily reflects higher revenues at SCW during 2000, as is more fully discussed below. For the year ended December 31, 2000, fully diluted earnings were $1.91 per share. Registrant had no dilutive securities outstanding in 1999. Water operating revenues increased by 5.7% in 2000 to $168.8 million from the $159.7 million reported in 1999. The increase was due to three factors (i) a 3.0% increase in water sales to customers of SCW, (ii) increased water rates authorized by the CPUC for certain of SCW's water customers, and (iii) additional sales from CCWC. New rates in four customer service areas and implementation of regional rates in the customer service areas that comprise SCW's Region III were effective June 27, 2000. Additional increases in 2000 reflected the general rate case step and attrition increases for a number of SCW's ratemaking areas effective 2000. For further information, see the section entitled "Regulatory Matters" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. Electric operating revenues of $14.4 million were 7.7% higher in 2000 as compared to 1999 due to a 6.8% increase in kilowatt-hour sales, primarily by residential and industrial customers. Other revenues rose from $390,000 in 1999 to $799,000 in 2000 due to higher management fees from increased non-regulated activities. Purchased water costs in 2000 increased by 15.2% to $41.6 million as compared to $36.1 million in 1999 due to a 9.6% increase in volumes purchased. The increase was also affected by a total of $1.6 million in refunds from the Water Replenishment District of Southern California (WRD) received during 1999. There were no similar refunds received in 2000. Costs of power purchased for resale to customers in SCW's Bear Valley Electric division in 2000 increased by 50.7% to $10.7 million from the $7.1 million recorded in 1999 due primarily to significant increases in wholesale market prices for energy in the state of California. Costs of power purchased for pumping increased slightly by 1.6% to $7.5 million in 2000 as compared to $7.4 million recorded in 1999, chiefly as a result of an increase in energy costs, the effect of which was partially offset by a decrease in pumped groundwater in SCW's water supply mix. Groundwater production assessments increased by 4.2% to $7.5 million in 2000 from $7.2 million in 1999 due primarily to increased costs for excess pumping in SCW's San Gabriel and San Dimas customer service areas to meet summer demands. A negative entry for the provision for supply cost balancing accounts reflects an under-collection of previously incurred supply costs. Conversely, a positive entry for the provision for supply cost balancing accounts reflects recovery of previously under-collected supply costs. SCW has a higher net under-collected position in 2000 than in 1999 reflecting the increased energy costs in SCW's Bear Valley electric service area, the aggregate effect of which was 9

partially offset by new water rates effective during 2000, authorized to collect previously incurred supply costs in SCW's various water customer service areas, as well as the WRD refunds during 1999 as discussed previously. For further information, see the sections entitled "Regulatory Matters" and "Accounting for Supply Costs" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. Other operating expenses increased by 7.4% from the $15.6 million recorded in 1999 reflecting increased costs for water treatment, and increased labor and billing costs due to additional billing and customer service contracts obtained by ASUS. Administrative and general expenses decreased by 8.7% to $26.1 million in 2000 from $28.6 million recorded in 1999. The decrease is due primarily to booking reduced reserves for litigation in 2000 and a reduction in pension expenses. For further information, see Part I, Item 3 in Legal Proceedings. Depreciation expense in 2000 increased by 11.7% to $15.3 million reflecting the effects of recording approximately $50 million in net plant additions during 1999, depreciation on which began in 2000. Maintenance expense increased to $10.3 million in 2000 compared to the recorded $9.8 million in 1999 due principally to increased maintenance on SCW's water supply sources and maintenance of water mains. Taxes on income increased by approximately 13.5% to $15.1 million in 2000 as compared to the $13.3 million in 1999 due primarily to a 15.2% increase in pre-tax income, the effect of which was partially offset by a slightly lower effective tax rate. Property and other tax expense increased by 7.6% in 2000 to $7.1 million due to higher property valuation, increased franchise fees associated with higher revenues, and increased payroll taxes due to increased labor costs. The loss of $99,000 in other income recorded for 2000 is related to the effect of recording amortization and interest expenses, starting January 2000, on SCW's entitlement in the State Water Project. For further information, see Note 8 of the "Notes to Financial Statements" included in Part II, Item 8 in Financial Statements and Supplementary Data. In 2000, interest expense increased by 9.3% to $14.1 million from the $12.9 million recorded in 1999 due to additional short-term borrowing at higher rates incurred by SCW to temporarily fund its capital expenditures. ACCOUNTING FOR SUPPLY COSTS As permitted by the CPUC prior to November 29, 2001, SCW maintained water and electric supply balancing accounts to account for under-collections and over-collections of revenues designed to recover such costs. Costs were recorded in income and charged to balancing accounts when such costs were incurred. The balancing accounts were reversed when such costs were recovered through rate adjustments or through refunds of previously incurred costs. SCW accrued interest on its supply cost balancing accounts at the rate prevailing for 90-day commercial paper. CCWC does not maintain a supply cost balancing account. On November 29, 2001, the CPUC ordered water utilities with existing water supply balancing accounts to cease booking amounts to such accounts. In its place, water utilities are now required to establish a memorandum account that works in a manner similar to the balancing account. As a result, the income statements of SCW will no longer include entries reflecting differences between actual unit water supply costs included in rates and actual water supply costs. SCW will not be entitled to recover any deferred costs for providing water service unless it is within its general rate case cycle and is earning less than its authorized rate of return on a weather normalized basis. As a result, any changes in water supply costs as well as any future authorized revenue increases for supply expenses may directly impact earnings. SCW may not be able to recover the under-collection of supply costs if it is earning a rate of return in excess of that allowed. SCW had a net under-collection position of $3.4 million in its water supply balancing account at December 31, 2001 compared to $2.5 million and $2.0 million at December 31, 2000 and December 31, 1999, respectively. Electric power costs incurred by SCW's Bear Valley Electric division will continue to be charged to a balancing account pursuant to the methodology in effect prior to November 29, 2001. The amount of the under-collection in the electric balancing account has increased from $2.8 million at December 31, 1999, to $8.6 million at December 31, 2000 and $22.4 million at December 31, 2001. Due to the nature of the regulatory process, there is a risk of disallowance of full recovery of costs or additional delays in the recovery of costs during any period in which there has been a substantial 10

run-up of costs. For further information, see the sections entitled "Regulatory Matters" and "Electric Energy Situation in California" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. LIQUIDITY AND CAPITAL RESOURCES AWR AWR funds its operating expenses and pays dividends on its outstanding Common and Preferred Shares primarily through dividends from its subsidiaries, principally SCW. AWR has a Registration Statement on file with the Securities and Exchange Commission (SEC) for issuance, from time to time, of up to $60 million in Common Shares, Preferred Shares and/or debt securities. As of December 31, 2001, approximately $31.1 million remained for issuance under this Registration Statement. During 2001, AWR maintained a $25 million credit facility, $20 million of which was outstanding at December 31, 2001. This credit facility expired on January 2, 2002 although AWR expects to enter into a new credit facility in the second quarter of 2002 in the amount of $75 million. SCW SCW funds the majority of its operating expenses, payments on its debt, and dividends on its outstanding Common Shares through internal sources. Internal sources of cash flow are provided primarily by retention of a portion of earnings, amortization of deferred charges and depreciation expense. Internal cash generation is influenced by factors such as weather patterns, environmental regulation, litigation, changes in supply costs, and timing of rate relief. For further information, see the sections entitled "Risk Factors" and "Electric Energy Situation in California" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. SCW also relies on external sources, including equity investments from AWR, long-term debt, contributions-in-aid-of-construction, advances for construction and install-and-convey advances, to fund the majority of its construction expenditures. In January 2001, SCW issued $20 million of long-term debt in a public offering with the proceeds used to reduce then outstanding bank borrowing. On March 30, 2001, AWR made an additional $25 million equity investment in SCW. On November 14, 2001, SCW filed a Registration Statement with the SEC for issuance, from time to time, of up to $100 million in debt securities. In December 2001, SCW issued $50 million of long-term debt under this Registration Statement that initially reduced bank borrowing incurred to fund capital expenditures and power purchase costs. Because of the seasonal nature of its water and electric operations, SCW utilizes its short-term borrowing capacity to finance current operating expenses, including expenses for purchased power distributed through its Bear Valley Electric customer service area. SCW has short-term revolving credit lines totaling an aggregate of $47 million. Of the aggregate amount, $13 million expires in May 2002, $10 million expires in July 2002 and $24 million expires in August 2002. SCW does not intend to enter into any new short-term revolving credit lines in 2002. CCWC CCWC funds the majority of its operating expenses, payments on its debt and dividends, if any, through internal sources. CCWC also relies on external sources, including long-term debt, contributions-in-aid-of-construction, advances for construction and install-and-convey advances, to fund the majority of its construction expenditures. ASUS ASUS funds its operating expenses primarily through contractual management fees. CONTRACTUAL OBLIGATIONS AND OTHER COMMITMENTS In addition to contractual maturities, Registrant has certain debt instruments that contain annual sinking fund or other principal payments. Registrant believes that it will be able to refinance debt instruments at their maturity through public issuance, or private placement, of debt or equity. Annual principal payments are generally made from cash flow from operations. 11

The following table reflects Registrant's contractual obligations and commitments to make future payments pursuant to contracts as of December 31, 2001. All obligations and commitments are obligations and commitments of SCW unless otherwise noted. ($ in thousands) Payments/Commitments Due by Period(1) ---------------------------------------------------------------- Total Less than 1 Year 1-3 Years 4-5 Years After 5 Years -------- ---------------- --------- --------- ------------- Notes/Debentures(2) $185,600 -- $12,500 -- $173,100 Private Placement Notes(3) 28,000 -- -- -- 28,000 Tax-Exempt Obligations(4) 20,820 87 285 218 20,231 Other Debt Instruments(5) 2,644 174 584 451 1,435 Bank Debt(6) 20,000 20,000 -- -- -- Preferred Shares(7) 1,920 1,920 -- -- -- Other Commitments(8) 50,072 -- -- -- -- Chaparral City Water Company(9) 9,388 499 1,684 620 6,585 TOTAL $318,444 $22,680 $15,053 $1,289 $229,351 - ---------- (1) Excludes interest, dividends, commitment and facility fees. (2) The Notes and Debentures are issued under an Indenture dated as of September 1, 1993. The Notes and Debentures do not contain any financial covenants that Registrant believes to be material or cross default provisions. (3) The private placement notes are issued pursuant to the terms of Note Agreements with substantially similar terms. The Note Agreements contain restrictions on the payment of dividends, minimum interest coverage requirements and a negative pledge. For a further discussion of the dividend restrictions, see the sections entitled "Frequency and Amount of Any Dividends Declared and Dividend Restrictions" included in Part II, Item 5 in Market for Registrant's Common Equity and Related Stockholder Matters. Pursuant to the Note Agreements, SCW must maintain a minimum interest coverage ratio of two times interest expense. SCW does not currently have any outstanding mortgages or other encumbrances on its properties. (4) Consists of obligations under a loan agreement supporting $8 million in debt issued by the California Pollution Control Financing Authority, $6 million in obligations supporting $6 million in certificates of participation issued by the Three Valleys Municipal Water District and $7 million of obligations incurred by SCW with respect to its 500 acre foot entitlement to water from the State Water Project. Except as described below, these obligations do not contain any financial covenants believed to be material to Registrant or any cross default provisions. SCW's obligations with respect to the certificates of participation issued by the Three Valleys Municipal Water District are supported by a letter of credit issued by Bank of America. SCW has reimbursement obligations to Bank of America that incorporate by reference SCW's obligations to Bank of America under its short-term revolving credit line with Bank of America discussed below in paragraph (6). The letter of credit expires on July 31, 2002. The letter of credit may be drawn if SCW has not obtained a replacement letter of credit prior to the expiration of this letter of credit. SCW has entered into an agreement with a developer for 350 acre-feet of its entitlement to water from the State Water Project. For further information, see the section entitled "Regulatory Matters-Disallowance of Costs" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. (5) Consists of $1.6 million outstanding under a fixed rate obligation incurred to fund construction of water storage and delivery facilities with the Three Valleys Municipal Water District, $0.6 million outstanding under a variable rate obligation incurred to fund construction of water delivery facilities with the Three Valleys Municipal Water District and an aggregate of $0.4 million outstanding under capital lease obligations. These obligations do not contain any financial covenants believed to be material to Registrant or any cross default provisions. (6) Consists of $20 million outstanding under a term loan facility for AWR that expired on January 2, 2002. (7) AWR intends to redeem or repurchase all of its outstanding Preferred Shares during the first quarter of 2002. (8) Other commitments consists of $47 million available for borrowing by SCW at December 31, 2001 under short-term revolving credit loans $13 million expiring in May 2002, $10 million expiring in July 2002 and $24 million expiring in July 2002, a $2,513,813 irrevocable letter of credit that expires on April 30, 2002 for its self-insured workers 12

compensation plan, an amount of $296,000 with respect to a $6,296,000 irrevocable letter of credit issued by Bank of America to support the certificates of participation of Three Valleys Municipal Water District (the other $6,000,000 is reflected under tax-exempt obligations) that expires on November 15, 2003, an irrevocable letter of credit in the amount of $250,000 that expires on October 1, 2002 for the deductible in Registrant's business automobile insurance policy and outstanding performance bonds of $12,500 to secure performance under franchise agreements with governmental agencies. None of these obligations contain any financial covenants believed to be material to Registrant or any cross default provisions. (9) Consists of $8.1 million of obligations under a loan agreement supporting Industrial Development Revenue Bonds due in 2006 and a $1.3 million repayment obligation to the United States Bureau of Reclamation. The loan agreement contains provisions that establishes a maximum of 65% debt in the capital structure, limits cash distributions when the percentage of debt in the capital structure exceeds 55% and requires a debt service coverage ratio of two times. The Bureau of Reclamation obligation does not contain any financial covenants believed to be material to Registrant or any cross default provisions. Under the terms of its power purchase contracts with Mirant Americas Energy Marketing, LP and Pinnacle West Capital Corporation, SCW is required to post security, at the request of the seller, if SCW is in default under the terms of the contract and the future value of the contract is greater than the future value of contracts of a similar term on the date of default. SCW will be in default under the terms of these contracts if its debt is rated less than BBB- by Standard & Poor's Ratings Service ("S&P") or Fitch, Inc. ("Fitch") or less than Baa3 by Moody's Investor Services, Inc ("Moody's"). SCW currently has a rating of A+ by S&P and A2 by Moody's. Fitch does not rate SCW. S&P debt ratings range from AAA (highest rating possible) to D (obligation is in default). Moody's debt ratings range from Aaa (best quality) to C (lowest quality). Securities ratings are not recommendations to buy, sell or hold a security and is subject to change or withdrawal at any time by the rating agency. ELECTRIC ENERGY SITUATION IN CALIFORNIA BACKGROUND INFORMATION The electric energy environment in California has changed as a result of the December 1995 CPUC decision on restructuring of California's electric utility industry and state legislation passed in 1996. On September 23, 1996, the State of California enacted legislation to provide a transition to a competitive market structure, which was expected to provide competition and customer choice, beginning January 1, 1998, with all consumers ultimately participating by 2002. SCW's Bear Valley electric customer service area was exempted by the CPUC from compliance with most of the provisions of the CPUC order and the state legislation. On January 17, 2001, the Governor of the State of California proclaimed a state of emergency in California due to shortages of electricity available to certain of California's utilities (resulting in blackouts), the unanticipated and dramatic increases in electricity prices and the insufficiency of electricity available from certain of California's utilities to prevent disruption of electric service in California. The Federal Energy Regulatory Commission ("FERC") also implemented a number of changes to the tariff for the California Independent Operator System ("Cal ISO") beginning in December 15, 2000 in an attempt to stabilize the market. The reasons for the high cost of energy are under investigation but are reported to include, among other things, limited supply caused by a lack of investment in new power plants to meet growth in demand, planned and unplanned outages of power plants, decreased availability of hydroelectric power from the Pacific Northwest due to lower than usual precipitation and higher demand for electricity in the region, transmission line constraints, increased prices for natural gas, the fuel used in many of the power plants serving the region, and a dysfunctional power market. Spot market prices dropped dramatically in the summer of 2001 and continue to remain low. A number of factors could, however, result in a substantial increase in spot market prices and the prices of long term contracts for power and capacity. The mitigation measures taken by FERC expire on September 30, 2002 despite the fact that there continues to be insufficient generation resources in California and throughout the West, transmission line constraints, constraints on natural gas pipeline capacity and a dysfunctional power market. In addition, the Cal ISO has proposed a number of market reforms, such as the imposition of an available capacity obligation ("ACAP") on all load-serving entities. The purpose of the ACAP obligation is to ensure that all load-serving entities have sufficient power resources to meet their maximum possible load. If an ACAP obligation of the type proposed by Cal ISO is adopted, SCW could be required to procure substantial additional power and capacity. The cost of procuring this additional power and capacity 13

could have a material adverse impact on SCW if SCW is not permitted to recover the costs of procuring this additional power and capacity from its ratepayers on a timely basis. POWER SUPPLY ARRANGEMENTS All electric energy sold by SCW to customers in its BVE customer service area is purchased from others. Historically, SCW purchased electric energy from the Southern California Edison unit of Edison International. However, in order to keep electric power costs as low as possible, SCW entered into an energy brokerage contract with Sempra Energy Corporation. SCW purchased electric energy for its BVE customer service area from Sempra during the period beginning March 26, 1996 through April 30, 1999. In May 1999, SCW entered into a one-year block forward purchase contract with Illinova Energy Partners for 12 megawatts (MWs) of power at a price of $28.00 per MW hour (MWh). In May 2000, SCW entered into a one-year, block forward purchase contract with Dynegy Power Marketing, Inc. (DYPM) for 12 MWs of electric energy for its BVE customer service area at a price of $35.50 per MWh. This contract expired April 30, 2001. SCW entered into a five-year, block forward purchase contract with Mirant Marketing to supply its BVE customer service area with 15 MWs of electric energy at a price of $95 per MWh beginning April 1, 2001 through December 31, 2006. On December 20, 2001, SCW filed a complaint with FERC seeking to reduce the amount charged by Mirant Marketing under the terms of this contract due to the dysfunctional power market. Management is unable to predict what if any action FERC will take with respect to this complaint. In June 2001, SCW executed an agreement with Pinnacle West Capital for an additional 8 MWs of electric energy to meet BVE's peak winter demands. The contract provides for pricing of $75 per MWh from November 1, 2001 to March 31, 2002, $48 per MWh from November 1, 2002 to March 31, 2003, and $36 per MWh from November 1, 2003 to March 31, 2004. The average minimum load at SCW's Bear Valley Electric customer service area has been approximately 12 MWs. The average winter load has been 18 MWs with a winter peak of 38 MWs when the snowmaking machines at the ski resorts are operating. Under the terms of a contract with DYPM that expires on April 30, 2002, DYPM has agreed to provide electric energy to SCW in excess of the amounts it has purchased under the forward block purchase contracts previously described, to sell excess energy purchased by SCW under the terms of these contracts, if requested by SCW, and to act as scheduling coordinator for SCW. However, SCW has entered into a separate agreement to have Automated Power Exchange, Inc. act as its scheduling coordinator and will not utilize the services of DYPM. SCW has withheld payment on $3.4 million invoiced by DYPM for the period December 20, 2000 through February 20, 2001, pending resolution of certain disputes. Based on information available to it, Registrant expects the amount in dispute to increase due to additional amounts billed by DYPM. TRANSMISSION CONSTRAINTS Demand for energy in SCW's Bear Valley Electric customer service area generally has been increasing. However, the ability of SCW to deliver purchased power to these customers is limited by the ability of the transmission facilities owned by Southern California Edison Company to transmit this power. For further information, see Legal Proceedings in Part I for a discussion of litigation between Edison and SCW regarding Edison's obligations to upgrade these transmission facilities. In order to meet these increasing energy demands, SCW is considering a number of options including (i) the purchase of electric energy from on-site generation facilities installed by a third party, (ii) the use of portable generation, and (iii) the installation of generation owned by SCW. Each of these options may result in further increases in electric energy prices for customers of SCW's BVE customer service area. CONSTRUCTION PROGRAM SCW maintains an ongoing distribution main replacement program throughout its customer service areas, based on the priority of leaks detected, fire protection enhancement and a reflection of the underlying replacement schedule. In addition, SCW upgrades its electric and water supply facilities in accordance with industry standards, local requirements and CPUC requirements. SCW's Board of Directors has approved anticipated net capital expenditures of approximately $55.4 million for 2002. Approved capital expenditures may be limited pending final CPUC approval of the settlement agreement regarding recovery of electric power costs at SCW's Bear Valley electric division. For further information, see the section entitled "Rate Matters-Changes in Rates" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. 14

CCWC has a net capital budget of $1.4 million for 2002. AWR and ASUS have no material capital commitments. However, ASUS actively seeks opportunities to own, lease or operate water and wastewater systems for governmental entities, which may involve significant capital commitments. REGULATORY MATTERS RATE REGULATION SCW is subject to regulation by the CPUC, which has broad powers with respect to service and facilities, rates, classifications of accounts, valuation of properties, the purchase, disposition and mortgaging of properties necessary or useful in rendering public utility service, the issuance of securities, the granting of certificates of public convenience and necessity as to the extension of services and facilities and various other matters. CCWC is subject to regulation by the ACC. Rates that SCW and CCWC are authorized to charge are determined by the CPUC and the ACC, respectively, in general rate cases and are derived using rate base, cost of service and cost of capital, as projected for a future test year in California and using an historical test year, as adjusted in Arizona. Rates charged to customers vary according to customer class and rate jurisdiction and are generally set at levels allowing for all prudently incurred costs, including a return on rate base sufficient to pay principal and interest on debt securities, preferred stock distributions and a reasonable rate of return on equity. Rate base generally consists of the original cost of utility plant in service, plus certain other assets, such as working capital and inventory, less accumulated depreciation on utility plant in service, deferred income tax liabilities and certain other deductions. Adjustments for purchased water and power are permitted in California, to a certain extent, but generally not Arizona. For further information, see the section entitled "Accounting for Supply Costs" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. Neither AWR nor ASUS are regulated by the CPUC. The CPUC does, however, regulate certain transactions between SCW and its affiliates. The ACC also regulates certain transactions between CCWC and its affiliates. The 22 customer service areas of SCW are grouped into 9 water districts and 1 electric district for ratemaking purposes. Water rates vary among the 9 ratemaking districts due to differences in operating conditions and costs. SCW monitors operations on a regional basis in each of these districts so that applications for rate changes may be filed, when warranted. Under the CPUC's practices, rates may be increased by three methods: (i) general rate case increases (GRC's), (ii) offsets for certain expense increases including but not limited to electricity supply cost offset and balancing account amortization, and (iii) advice letter filings related to certain plant additions and other operating cost increases. GRC's are typically for three-year periods, which include step increases for the second and third year. Rates are based on a forecast of expenses and capital costs. GRC's have a typical regulatory lag of one year. Offset rate increases and advice letter filings typically have a two to four month regulatory lag. CHANGES IN RATES The following table lists information on estimated annual rate changes approved by the CPUC during 2001, 2000 and 1999. ($ in 000's) Supply Balancing General Cost Account and Step Advice Year Offset Amortization Increases Letters Total ---- ------- ------------ --------- ------- ------- 2001 $ 1,364 $ 4,422 $ 6,943 $ 595 $13,324 2000 -- (1,474) 6,973 1,040 6,539 1999 $ 23 $ 1,349 $15,175 $ 657 $17,204 New water rates with an annual increase of approximately $2.5 million for seven ratemaking districts in SCW's Region I were implemented in January 2001. SCW's application to combine the seven ratemaking customer service areas into one regional rate was, however, denied by the CPUC. Step increases of approximately $1.7 million for the customer service areas in SCW's Region III were also effective in January 2001. An attrition increase of approximately $2.8 million for Region II was in effect from February 2001. 15

As of December 31, 2001, SCW had accrued approximately $22.4 million in under-collected purchased power costs included in the electric balancing account. In May 2000, SCW filed an Advice Letter with the CPUC for recovery over a five-year period of approximately $2.4 million in under-collected power costs and removal of a negative amortization authorized by the CPUC in 1997. The CPUC issued a final order on May 24, 2001 authorizing an overall rate increase of 12.5%, with a condition of conducting a subsequent audit on the expenses included in the electric balancing account. The audit has been conducted and provided to the CPUC. On August 23, 2001, the CPUC also approved a second Advice Letter filed by SCW on April 9, 2001 seeking recovery, over five years, of an additional under-collection of $8.7 million for energy costs. Rates in SCW's BVE customer service area have increased by approximately 14.8% as a result. On May 11, 2001, SCW filed with the CPUC for an additional increase in electric rates to recover energy costs under the purchase agreement with Mirant Marketing. SCW subsequently withdrew the Advice Letter and filed an application on August 17, 2001 with the CPUC, along with a motion requesting immediate recovery of these costs, subject to refund after completion of the review process. The CPUC rejected SCW's motion for immediate recovery. On February 8, 2002, a settlement agreement among SCW, all intervening parties and the Office of Ratepayer Advocates ("ORA") was filed with the CPUC that will permit SCW to recover $77 per MWh of purchased power costs through rates. SCW will only be allowed to include up to a weighted annual energy purchase cost of $77 per MWh each year for 10 years in its balancing account. To the extent SCW's actual average annual weighted cost for purchased power is less than $77 per MWh, the differential will recover amounts included in the electric supply balancing account. Conversely, to the extent that actual average annual weighted costs for power purchased exceed the $77 per MWh amount, SCW will not be able to include these amounts in its balancing account and such amounts will be expensed against income. SCW has established approximately $7.9 million in reserves as of December 31, 2001 against potential non-recovery of electric power costs. In addition, the settlement extended the previously approved surcharges for an additional five years to allow SCW an opportunity to collect amounts remaining in its electric cost balancing account. The proposed settlement also requires SCW to pursue its complaint filed with FERC in which SCW has requested FERC to reduce the prices in its power purchase contract with Mirant Marketing due to the dysfunctional power market that existed at the time the agreement was signed. A final decision in this matter is expected during the second quarter of 2002. Management believes the CPUC will support the settlement agreement, but is unable to predict when or if the CPUC will authorize recovery of any or all of the costs agreed to in the settlement. For further information, see the sections entitled "Liquidity and Capital Resources" and "Electric Energy Situation in California" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. In March 2001, the CPUC approved SCW's Advice Letters to increase costs of purchased power incurred to pump water for its water customers by $761,351 included in base water rates for each of its ratemaking districts. In April 2001, SCW filed additional Advice Letters by ratemaking areas to increase water rates by approximately $2.3 million company-wide to recover additional electric base rate increases, authorized recently by the CPUC for the Southern California Edison Company and the Pacific Gas and Electric Company. The CPUC approved in the fourth quarter of 2001 increases of approximately $672,900 in base water rates. For further information, see the section entitled "Electric Energy Situation in California" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. The remaining Advice Letters filed by SCW to recover increased power costs used for pumping were rejected by the CPUC due to the change in procedures for collections of water supply costs on November 29, 2001. See the section entitled "Accounting for Supply Costs" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. DISALLOWANCE OF COSTS In 1993, the CPUC disallowed $1.6 million of costs incurred in construction of a water treatment facility in SCW's Clearlake customer service area and Registrant wrote off the disallowed amount at that time. Based on new water quality standards, in 2000, SCW re-applied to the CPUC for inclusion of the disallowed amount in rate base. A draft decision issued on March 30, 2001 by the CPUC allows SCW to include $500,000 of the $1.6 million in the regulated rate base, although an alternate draft decision issued by one of the CPUC Commissioners proposed to deny the relief sought by SCW in its application. An Administrative Law Judge subsequently reopened the proceeding in August 2001 requiring additional information. A final order is not anticipated until the second quarter of 2002. 16

On April 22, 1999, the CPUC issued an order denying SCW's application seeking approval of its recovery through rates of costs associated with its 500 acre-foot participation in the Coastal Aqueduct Extension of the State Water Project (SWP). SCW's participation in the SWP commits it to a 40-year entitlement. SCW's investment of approximately $9.5 million in SWP is currently included in Other Property and Investments. The remaining balance of the related liability of approximately $7 million is recorded as other long-term debt. In October 2001, SCW entered into an agreement with a developer, which obligates the developer to make payments to SCW in exchange for SCW's reservation and dedication of up to 350 acre-feet per year of the SWP entitlement for a five-year period. SCW intends to recover its remaining investment from other developers or through a sale of its remaining entitlement. SCW believes that its full investment and on-going costs associated with its ownership will be recovered. OTHER REGULATORY MATTERS In December 1999, Registrant agreed to acquire Peerless Water Co., a privately owned water company in Bellflower, California, subject to satisfaction of certain conditions, including CPUC approval. The transaction, however, was denied by the CPUC on November 29, 2001. As a result, the acquisition agreement with Peerless Water Co. has been terminated. There are no active regulatory proceedings affecting CCWC or its operations. ENVIRONMENTAL MATTERS 1996 AMENDMENTS TO FEDERAL SAFE DRINKING WATER ACT On August 6, 1996, amendments (the 1996 SDWA amendments) to the Safe Drinking Water Act (the SDWA) were signed into law. The 1996 SDWA revised the 1986 amendments to the SDWA with a new process for selecting and regulating contaminants. The U. S. Environmental Protection Agency (EPA) can only regulate contaminants that may have adverse health effects, are known or likely to occur at levels of public health concern, and the regulation of which will provide "a meaningful opportunity for health risk reduction." The EPA has published a list of contaminants for possible regulation and must update that list every five years. In addition, every five years, the EPA must select at least five contaminants on that list and determine whether to regulate them. The new law allows the EPA to bypass the selection process and adopt interim regulations for contaminants in order to address urgent health threats. Current regulations, however, remain in place and are not subject to the new standard-setting provisions. The DOHS, acting on behalf of the EPA, administers the EPA's program in California. The 1996 SDWA amendments allow the EPA to base primary drinking water regulations on risk assessment and cost/benefit considerations and on minimizing overall risk. The EPA must base regulations on best available, peer-reviewed science and data from best available methods. For proposed regulations that involve the setting of maximum contaminant levels (MCL's), the EPA must use, and seek public comment on, an analysis of quantifiable and non-quantifiable risk-reduction benefits and costs for each such MCL. SCW and CCWC currently test their wells and water systems according to requirements listed in the SDWA. Water from wells found to contain levels of contaminants above the established MCL's is treated to reduce contaminants to acceptable levels before it is delivered to customers or the wells are shut down. Since the SDWA became effective, SCW has experienced increased operating costs for testing to determine the levels, if any, of the constituents in SCW's sources of supply and additional expense to lower the level of any contaminants in order to meet the MCL standards. Such costs and the costs of controlling any other contaminants may cause SCW to experience additional capital costs as well as increased operating costs. The CPUC and ACC ratemaking processes provide SCW and CCWC with the opportunity to recover prudently incurred capital and operating costs associated with water quality. Management believes that such incurred and expected future costs will be authorized for recovery by the CPUC and ACC, as appropriate. PROPOSED ENHANCED SURFACE WATER TREATMENT RULE On July 29, 1994, the EPA proposed an Enhanced Surface Water Treatment Rule (ESWTR), which would require increased surface-water treatment to decrease the risk of microbial contamination. The EPA has proposed several versions of the ESWTR for promulgation. The version selected for promulgation will be determined based on data collected by certain 17

water suppliers and forwarded to the EPA pursuant to EPA's Information Collection Rule, which requires such water suppliers to monitor microbial and other contaminants in their water supplies and to conduct certain tests in respect of such contaminants. The EPA has adopted an Interim ESWTR applicable only to systems serving greater than 10,000 persons. On April 10, 2000, EPA published the proposed Long Term 1 Enhanced Surface Water Treatment Rule and Filter Backwash Rule (LT1FBR) in the Federal Register. This proposed rule will apply to each of SCW's five surface water treatment plants and the CCWC's surface water treatment plant. It basically extends the requirements of the ESWTR to systems serving less than 10,000 persons and will require some systems to institute changes to the return of recycled filter backwash flows within the treatment process to reduce the effects of recycled water on compromising microbial control. Registrant is presently unable to predict the ultimate impact of the LT1FBR, but it is anticipated that all plants will achieve compliance within the three year to five-year time frames identified by EPA. REGULATION OF DISINFECTANT/DISINFECTION BY-PRODUCTS SCW and CCWC are also subject to regulations concerning disinfectant/disinfection by-products (DBP's). Stage I of the regulations were effective in November 1998 with full compliance required by 2002. Stage I requires reduction of trihalomethane contaminants from 100 micrograms per liter to 80 micrograms per liter. Two of SCW's systems are immediately impacted by this rule. SCW implemented modifications to the treatment process in its Bay Point and Cordova systems. Both systems were in full compliance by the end of 2001. A third SCW plant will require treatment modifications in order to comply with this rule. SCW is conducting studies to determine the best treatment methods to comply with this rule. The EPA is not allowed to use the new cost/benefit analysis provided for in the 1996 SDWA amendments for establishing the Stage II rules applicable to DBP's but may utilize the regulatory negotiating process provided for in the 1996 SDWA amendments to develop the Stage II rule. The final rule is expected in 2002. GROUND WATER RULE On May 10, 2000, the EPA published the proposed Ground Water Rule (GWR), which establishes multiple barriers to protect against bacteria and viruses in drinking water systems that use ground water. The proposed rule will apply to all U.S. public water systems that use ground water as a source. The proposed GWR includes system sanitary surveys conducted by the state to identify significant deficiencies; hydrogeologic sensitivity assessments for undisinfected systems, source water microbial monitoring by systems that do not disinfect and draw from hydrogeologically sensitive aquifer or have detected fecal indicators within the system's distribution system; corrective action; and compliance monitoring for systems which disinfect to ensure that they reliably achieve 4-log (99.99%) inactivation or removal of viruses. The GWR is scheduled to be issued as a final regulation in 2002. While no assurance can be given as to the nature and cost of any additional compliance measures, if any, SCW and CCWC do not believe that such regulations will impose significant compliance costs, since they already currently engage in disinfection of their groundwater systems. REGULATION OF RADON AND ARSENIC The regulation on arsenic was published in January 2001 with a new federal standard of 10 parts per billion (ppb). Compliance with an MCL of 10 ppb will require implementation of wellhead treatment remedies for eight affected wells in SCW's system and three wells in CCWC's system. However, the EPA subsequently withdrew the pending arsenic standard for a sixty-day review to seek independent reviews of both the science behind the standard and of the cost estimates to communities of implementing the rule. On October 31, 2001, EPA announced that the arsenic standard in drinking water would be 10 parts per ppb. The effective date for utilities to comply with the standard will be January 2006. It is still not clear what will happen between now and the current effective date of the arsenic regulation of February 22, 2002. No further actions by EPA would simply make this regulation become effective as of that date. The EPA has proposed new radon regulations following a National Academy of Sciences risk assessment and study of risk-reduction benefits associated with various mitigation measures. The National Academy of Sciences study is in agreement with much of EPA's original findings but has slightly reduced the ingestion risk initially assumed by EPA. EPA established an MCL of 300 Pico Curies per liter based on the findings and has also established an alternative MCL of 4000 Pico Curies per liter, based upon potential mitigation measures for overall radon reduction. It is our understanding that the United States Office of Management and Budget has sent the radon rule back to EPA for reconsideration. The final rule was expected to be effective in August 2000, but has been delayed. SCW and CCWC currently monitor their wells for radon in order to determine the best treatment appropriate for affected wells. 18

VOLUNTARY EFFORTS TO EXCEED MINIMUM SURFACE WATER TREATMENT REQUIREMENTS SCW is a voluntary member of the EPA's "Partnership for Safe Water", a national program designed to further protect the public from diseases caused by cryptosporidium and other microscopic organisms. As a volunteer in the program, SCW commits to exceed minimum operating requirements governing surface water treatment, optimize surface water treatment plant operations and ensure that its surface water treatment facilities are performing as efficiently as possible. FLUORIDATION OF WATER SUPPLIES SCW is subject to State of California Assembly Bill 733, which requires fluoridation of water supplies for public water systems serving more than 10,000 service connections. Although the bill requires affected systems to install treatment facilities only when public funds have been made available to cover capital and operating costs, the bill requires the CPUC to authorize cost recovery through rates should public funds for operation of the facilities, once installed, become unavailable in future years. AMMONIUM PERCHLORATE ACTION LEVEL ACTIVITIES The California Department of Health Services (DOHS) recently reduced the action level for ammonium perchlorate. Although neither the EPA nor the DOHS have established a drinking water standard for ammonium perchlorate. In January 1997 DOHS established an action level of 18 parts per billion (ppb). Action levels are advisory in nature and are not enacted into law. In January 2002, SCW was informed that DOHS has reduced the action level from 18 ppb to a level of 4 ppb, based upon new reference dosage for health risk information from EPA. SCW has removed eight wells from service in four separate systems since they contained ammonium perchlorate in amounts in excess of this reduced action level. SCW is continuing to periodically monitor all its wells to determine that levels of perchlorate are below the action level currently in effect. MATTERS RELATING TO SCW'S ARDEN-CORDOVA SYSTEM In January 1997, SCW was notified that ammonium perchlorate in amounts above the state-determined action level had been detected in three of its wells serving its Rancho-Cordova system. Aerojet-General Corp. has, in the past, used ammonium perchlorate in oxidizing rocket fuels. SCW took the three wells detected with ammonium perchlorate in excess of the 1997 action levels out of service. In April 1997, SCW found ammonium perchlorate in three additional wells and, at that time, removed those wells from service until it was determined that the levels were below the state-determined action level. Those wells were returned to service. SCW periodically monitors these wells to determine that levels of ammonium perchlorate are below the action level currently in effect. In January 2002, SCW was informed that DOHS was reducing the action level from 18 ppb to 4 ppb and subsequently removed three wells from service since they contained ammonium perchlorate in amounts in excess of this reduced action level. In February 1998, SCW was informed that nitrosodimethylamine (NDMA) had been detected in amounts in excess of the EPA reference dosage for health risks in four of its wells in its Rancho-Cordova system. The wells have been removed from service. An additional well was also removed from service in September 1999 due to the contamination and another well was removed from service in January 2002. The DOHS established an initial action level of 2 parts per trillion (ppt). In February 2002, DOHS increased the action level to 10 ppt. Management is investigating the impact, if any, that the increase in the action level may have on its abilities to put certain wells back into service. NDMA is an additional by-product from the production of rocket fuel and it is believed that such contamination is related to the activities of Aerojet. Aerojet has reimbursed SCW for constructing a pipeline to interconnect with the City of Folsom water system to provide an alternative source of water supply in SCW's Rancho-Cordova customer service area and has reimbursed SCW for costs associated with the drilling and equipping of two new wells. As of December 31, 2001, Aerojet had previously reimbursed SCW $4.5 million of the approximately $17 million in costs SCW has incurred. The remainder of the costs is subject to further reimbursement, including interest. Reimbursements received from Aerojet will reduce SCW's utility plant and costs of purchased water. For further information regarding litigation related to contamination of ground water in Sacramento County, see the section entitled "Other Water Quality Litigation" included in Part I, Item 3 in Legal Proceedings. 19

MATTERS RELATING TO SCW'S CULVER CITY SYSTEM The compound, methyl tertiary butyl ether (MTBE), an oxygenate used in reformulated fuels, has been detected in the Charnock Basin, located in the city of Santa Monica and within SCW's Culver City customer service area. At the request of the Regional Water Quality Control Board, the City of Santa Monica and the California Environmental Protection Agency, SCW removed two of its wells in the Culver City system from service in October 1996 to help in efforts to avoid further spread of the MTBE contamination plume. Neither of these wells have been found to be contaminated with MTBE. SCW is purchasing water from the Metropolitan Water District of Southern California (MWD) at an increased cost to replace the water supply formerly pumped from the two wells removed from service. Pursuant to an agreement with SCW in December 1998, two of the potentially responsible parties (the Participants) have reimbursed SCW's legal and consulting costs related to this matter and for increased costs incurred by SCW in purchasing replacement water. However, a notice of termination from the Participants to the settlement agreement was received in October 1999 claiming overpayments for replacement water in excess of SCW's water rights. No assurances can be given that future negotiations will result in complete restoration of SCW's water rights or that continued reimbursement of SCW's costs will be forthcoming. MATTERS RELATING TO THE CHARNOCK BASIN On September 22, 1999, the U.S. EPA and the Los Angeles Regional Water Quality Control Board ordered Shell Oil Company, Shell Oil Products Company and Equilon Enterprises LLC to provide replacement drinking water to both SCW and the City of Santa Monica due to MTBE contamination of the Charnock Basin drinking water. The EPA has ordered Shell Oil to reimburse SCW for water replacement costs. The agencies are continuing to investigate the causes of MTBE pollution and intend to ensure that all responsible parties contribute to its clean up. SCW is unable to predict the outcome of the EPA's enforcement efforts. On April 25, 2001, Registrant filed a lawsuit against all the potentially responsible parties, who stored, transported and dispensed gasoline containing methyl tertiary butyl ether (MTBE) in underground storage tanks, pipelines or other related infrastructure. MTBE polluted and contaminated water existed in areas of the basin from which SCW has pumped water through its Charnock Well Field. As a result, SCW ceased operation of its Charnock Well Field in October 1996. Registrant has reached an agreement in this matter that assigns the prosecution of litigation against the potentially responsible parties to the City of Santa Monica, California (Santa Monica). As part of the agreement and in exchange for an assignment payment, Santa Monica will prosecute the case against the potentially responsible parties. Registrant expects that Santa Monica will sign the agreement by the end of the first quarter of 2002. For further information, see section entitled "Other Water Quality Litigation" included in Part I, Item 3 in Legal Proceedings. MATTERS RELATING TO SCW'S YORBA LINDA SYSTEM The compound MTBE has been detected in three wells serving SCW's Yorba Linda system. Two of the wells are standby wells and the third well has not shown MTBE above the DOHS secondary standard of 5.0 ppb at this time. SCW has constructed an interconnection with the MWD to provide for additional supply in the event the third well experiences levels of detection in excess of the DOHS standard. SCW has met with the Regional Water Quality Control Board, the Orange County Water District, the City of Anaheim, the DOHS and three potentially responsible parties (PRP's) to define the extent of the MTBE contamination plume and assess the contribution from the PRP's. The PRP's have voluntarily initiated a work plan for regional investigation. While there have not been significant disruptions to the water supply in Yorba Linda at this point in time, no assurances can be given that MTBE contamination will not increase in the future. SECURITY ISSUES Since the tragic events of September 11, 2001, water utilities, including Registrant, have been advised to increase security at key facilities in order to avoid contamination of water supplies and other disruptions of service. Registrant has implemented a number of steps to address this concern, including the engagement of a security firm to develop further protection measures and an ongoing review of new industry and regulatory agency security measures. Although Registrant has not experienced any material increase in costs related to these measures, management is unable to predict what, if any, additional measures will be implemented and what such measures may cost. Registrant intends to seek recovery of any such 20

costs from the CPUC and the ACC. Management is unable to predict if these regulatory bodies will authorize recovery of any or all of these costs. WATER SUPPLY SCW'S WATER SUPPLY During 2001, SCW supplied a total of 84,103,000 CCF of water. Of this amount, approximately 58.5% came from pumped sources and 39.6% was purchased from others, principally the MWD. The Bureau of Reclamation (the Bureau) supplied the remaining amount under a no-cost contract. During 2000, SCW supplied 87,439,000 CCF of water, 55.7% of which came from pumped sources, 42.4% was purchased, and the Bureau supplied the remainder. SCW's water supply and revenues are significantly affected by changes in meteorological conditions. For the water year ending in September of 2001, California precipitation was at 75% of normal levels with the biggest deficits in Northern California. Southern California experienced only slightly less precipitation than normal, 92% for South Coast and 104% for Central Coast. In January of 2001 statewide reservoirs were at 107% of normal levels. For 2002 statewide the numbers should be much the same albeit reversed with Northern California returning to normal precipitation levels and Southern California entering a slightly dryer and warmer weather pattern. Statewide from October to December precipitation was 130% of normal and reservoirs in January of 2002 were at 95% of normal. As of January 22, 2002, snow pack water content was 105% of average with the North at 110%, Central at 105%, and Southern California at 100%. In the Pacific where the El Nino/Southern Oscillation (ENSO) is formed, near average, sea surface temperature (SST) conditions are predicted through March 2002, followed by slightly warmer than normal SST from mid-March through June. Should the SST warming trend continue, the later half of 2002 could see a mild El Nino effect with associated increases in precipitation for areas of the Southwestern part of the United States. Although overall groundwater conditions remain at adequate levels, certain of SCW's groundwater supplies have been affected to varying degrees by various forms of contamination which, in some cases, have caused increased reliance on purchased water in its supply mix. For further information, see Part I, Item 3 in Legal Proceedings. The MWD is a water district organized under the laws of the State of California for the purpose of delivering imported water to areas within its jurisdiction. Registrant has 57 connections to the water distribution facilities of MWD and other municipal water agencies. MWD imports water from two principal sources: the Colorado River and the State Water Project (SWP). Available water supplies from the Colorado River and the SWP have historically been sufficient to meet most of MWD's requirements and MWD's supplies from these sources are anticipated to remain adequate through 2002. MWD's import of water from the Colorado River is expected to decrease in future years due to the requirements of the Central Arizona Project (CAP). In response, MWD has taken a number of steps to secure additional storage capacity and to increase available water supplies, by effecting transfers of water rights from other sources. Foremost among the safeguards is Diamond Valley Reservoir, a reservoir in southwest Riverside County. Capable of holding 800,000 acre-feet (AF) or 269 billion gallons, the reservoir is currently more than half full. CCWC'S WATER SUPPLY The Colorado River flow has been low. For the 2001 water year 6,929,200 AF of water flowed into Lake Powell from the Colorado River, which is only 52% of normal. However the Lake itself is currently at 75% of capacity, which is 95% of normal for the end of December 2001. If the SST warming trend continues, it is likely that precipitation will return to normal levels over the 2002 water year. In December 2001 there was 279,700 AF of water flow into Lake Powell from the Colorado River, which is 75% of average. The snow pack water content in the upper Colorado River Basin was 70% of normal as of January 31, 2002. The National Weather service expects that normal seasonal rain and snow should gradually improve water supply in Registrant's water service areas. CCWC obtains its water supply from three operating wells and from Colorado River water delivered by the CAP. The majority of CCWC's water supply is obtained from its CAP allocation and well water is used for peaking capacity in excess of treatment plant capability, during treatment plant shutdown, and to keep the well system in optimal operating condition. CCWC has an Assured Water Supply designation, by decision and order of the Arizona Department of Water Resources, providing in part that, subject to its requirements, CCWC currently has a sufficient supply of ground 21

water and CAP water which is physically, continuously and legally available to satisfy current and committed demands of its customers, plus at least two years of predicted demands, for 100 years. Notwithstanding such a designation, CCWC's water supply may be subject to interruption or reduction, in particular owing to interruption or reduction of CAP water. In the event of interruption or reduction of CAP water, CCWC can currently rely on its well water supplies for short-term periods. However, in any event, the quantity of water CCWC supplies to some or all of its customers may be interrupted or curtailed, pursuant to the provisions of its tariffs. BUSINESS SEGMENTS AWR currently has three principal business units: water service and electric distribution utility operations conducted through its SCW subsidiary, water service utility operations conducted through its CCWC subsidiary, and non-utility activities conducted through its ASUS subsidiary. All activities of SCW currently are geographically located within the State of California. All activities of CCWC are located in the state of Arizona. All activities of ASUS are conducted in California and Arizona. Both SCW and CCWC are regulated utilities. On a stand-alone basis, AWR has no material assets other than its investments in its subsidiaries. For further information, see Note 11 to the "Notes to Financial Statements" included in Part II, Item 8 in Financial Statements and Supplementary Data. RISK FACTOR SUMMARY You should carefully read the risks described below and other information in this Form 10-K in order to understand certain of the risks of our business. OUR LIQUIDITY, AND IN CERTAIN CIRCUMSTANCES, EARNINGS, COULD BE ADVERSELY AFFECTED BY INCREASES IN ELECTRICITY PRICES IN CALIFORNIA. Under California law, we are permitted to file for a rate increase to recover electric power costs not being recovered in current rates. Increases in electric power costs generally have no direct impact on profit margins, unless recovery of these costs is disallowed, but do affect cash flows and can therefore impact the amount of our capital resources. Electric power costs increased substantially in California during the fall of 2000 until the summer of 2001. As of December 31, 2001, SCW had accrued $22.4 million in unrecovered power costs in its electric balancing accounts. FERC mitigation measures are expected to expire on September 30, 2002. In addition, Cal ISO has proposed a number of market reforms that could require SCW to procure substantial additional power and/or capacity. This could result in an increase in the level and volatility of electric prices in California. We have been funding these power costs from our short-term borrowing facilities. In addition, in April 2001, the Company implemented a Cash Preservation Plan to control costs and temporarily to limit capital and maintenance expenditures. SCW has filed Advice Letters to recover the under-collection of power costs in its water and electric balancing accounts and intends to continue to do so until such time as its actual power costs are being fully recovered in rates. However, due to the nature of the regulatory process, there is a risk of disallowance of full recovery of supply costs during any period in which there has been a substantial run-up in these costs. Any material disallowance of purchased power costs could have a material adverse impact on cash flow and earnings. In addition, we believe that timely action by the CPUC to authorize the recovery of these costs is necessary to avoid a material adverse effect on SCW's financial condition. Delays in obtaining regulatory approval or disallowance of recovery of costs could also affect SCW's ability to pay dividends to AWR. AWR's ability to pay dividends on its Common Shares is dependent upon the payment of dividends by SCW. We have reached a settlement with the CPUC Staff and all other intervening parties that would authorize us to included $0.077 per kilowatt-hour (KWh) in rates to recover our electric power costs. If our actual annual costs exceed this amount, we cannot recover the excess and the amount will be expensed against income. If our actual annual energy costs are less that $0.077 per KWh, we can use this difference to collect amounts previously included in the balancing account. We are unable to predict if the CPUC will approve the settlement and, if the settlement is approved, whether or not the CPUC will implement new rates. The Company has established approximately $7.9 million in reserves for its Bear Valley Electric division for possible non-recovery of power costs included in the electricity supply cost balancing accounts. 22

CHANGES IN WATER SUPPLY COSTS, EITHER UNIT COST CHANGE OR SUPPLY MIX CHANGE, WILL DIRECTLY IMPACT THE COMPANY'S EARNINGS. Prior to November 29, 2001, we recovered certain water supply costs through a balancing account mechanism. Water supply costs include the cost of purchased water and power and groundwater production assessments. The balancing account was not, however, designed to insulate SCW's earnings against changes in supply mix. As a result, SCW was not permitted to recover increased costs due to increased use of purchased water, which is generally more expensive than groundwater, through the balancing account mechanism. On November 29, 2001, the CPUC ordered SCW to suspend the use of all current water balancing account, and instead started a memorandum account for each offsettable expense of purchased water, purchased power and pump tax for its water service areas. We may recover certain water supply costs based on the memorandum account if we are within our rate case cycle and we are not earning an amount in excess of our authorized rate of return. SCW may not otherwise recover increased costs due to increased unit cost. Additionally, changes in water supply costs compared to the authorized amount, as well as any future authorized offset increases may directly affect our earnings. SIGNIFICANT CLAIMS HAVE BEEN ASSERTED AGAINST US IN WATER QUALITY LITIGATION. SCW and others have been sued in twenty water quality related lawsuits alleging personal injury and property damage as a result of the delivery of water that was allegedly contaminated. Seventeen of the lawsuits involve plaintiffs who received water from the San Gabriel Basin in Los Angeles County. The other lawsuits involve plaintiffs in Sacramento County. In March 1998, the CPUC issued an Order Instituting Investigation as a result of water quality lawsuits being filed against water utilities in California. On November 2, 2000, the CPUC issued a final order concluding that the CPUC has jurisdiction to regulate the service of water utilities with respect to the health and safety of that service; that DOHS requirements governing drinking water quality adequately protect the public health and safety; and that regulated water utilities, including SCW, have satisfactorily complied with past and present drinking water quality requirements. On February 5, 2002, the California Supreme Court ruled that water utilities regulated by the CPUC may be sued for damages based on allegations that the utility failed to comply with federal and state safe drinking water requirements. As a result, plaintiffs may proceed on their claims against SCW to the extent that these claims are based on violations of federal and state law. SCW is unable to predict the outcome of any of this litigation or the extent to which it will be able to recover its litigation costs from ratepayers or other third parties. OUR OPERATING COSTS HAVE INCREASED AND ARE EXPECTED TO CONTINUE TO INCREASE AS A RESULT OF GROUNDWATER CONTAMINATION. SCW's operations have been impacted by groundwater contamination in certain of its service territories. We have taken a number of steps to address this contamination, including the removal of wells from service, the construction of water treatment facilities and securing alternatives sources of supply from other areas not affected by the contamination. In some cases, potentially responsible parties have reimbursed us for our costs. In other cases, we have taken legal action against parties that we believe to be potentially responsible for the contamination. Certain government officials have suggested that water producers, such as SCW and CCWC, may have liability under certain environmental statutes if their pumping operations affect the movement of the contamination. SCW has been required to remove certain wells from service because its pumping activities might affect the movement of contamination in other service areas. Currently, neither the Environmental Protection Agency nor any other governmental agency has identified the Company or, to our knowledge, any other water producer, as a potentially responsible party. We cannot assure you, however, that SCW or CCWC will not be identified as a potentially responsible party in the future. Our future results of operations could be adversely affected if either SCW or CCWC is required to pay clean-up costs and is not allowed to recover such costs in rates. 23

ENVIRONMENTAL REGULATION HAS INCREASED, AND IS EXPECTED TO CONTINUE TO INCREASE, OUR OPERATING COSTS. SCW and CCWC are subject to increasingly stringent environmental regulations that will result in increasing capital and operating costs. These regulations include: - The 1996 amendments to the Safe Drinking Water Act that require increased testing and treatment of water to reduce specified contaminants to maximum contaminant levels - Approved regulations requiring increased surface-water treatment to decrease the risk of microbial contamination; these regulations will affect SCW's five surface water treatment plants and one CCWC plant - Additional regulation of disinfection/disinfection byproducts expected to be adopted before the end of 2002; these regulations will potentially affect two of SCW's systems - Additional regulations expected to be adopted requiring disinfection of certain groundwater systems - Currently pending regulation of arsenic and radon - California customer requirements to fluoridate public water systems serving over 10,000 customers - Reduction in the action level for ammonium perchlorate to 4 ppb in 2002; we have removed 8 wells from service due to the presence ammonium perchlorate above action levels. SCW and CCWC may be able to recover costs incurred to comply with these regulations through the ratemaking process for their regulated systems. We may also be able to recover certain of these costs under our contractual arrangements with municipalities. In certain circumstances, we may be able to recover costs from parties responsible or potentially responsible for contamination. THE ADEQUACY OF OUR WATER SUPPLIES DEPENDS UPON A VARIETY OF FACTORS BEYOND OUR CONTROL. The adequacy of our water supplies varies from year to year depending upon a variety of factors, including: - Rainfall - Availability of Colorado River water - The amount of water stored in reservoirs - The amount of water used by our customers and others - Water quality, and - Legal limitations on use Population growth and increases in the amount of water used have increased limitations on use to prevent over-drafting of groundwater basins. The import of water from the Colorado River, one of SCW's important sources of supply, is expected to decrease in future years due to the requirements of the Central Arizona Project ("CAP"). We have also taken wells out of service due to groundwater contamination. CCWC obtains its water supply from operating wells and from the Colorado River through the CAP. CCWC's water supply may be subject to interruption or reduction if there is an interruption or reduction in CAP water. Water shortages may affect us in a variety of ways: - They adversely affect supply mix by causing us to rely on more expensive purchased water - They adversely affect operating costs - They may result in an increase in capital expenditures for building pipelines to connect to alternative sources of supplies and reservoirs and other facilities to conserve or reclaim water We may be able to recover increased operating and construction costs for our regulated systems through the ratemaking process. We may also be able to recover certain of these costs under the terms of our contractual agreements with municipalities. In certain circumstances, we may recover these costs from third parties that may be responsible, or potentially responsible, for groundwater contamination. 24

OUR EARNINGS ARE GREATLY AFFECTED BY WEATHER DURING DIFFERENT SEASONS. The demand for water and electricity varies by season. Therefore, the results of operations for one period may not indicate results to be expected in another period. For instance, most water consumption occurs during the third quarter of each year when weather tends to be hot and dry. On warm days, use of water by residential and commercial customers may be significantly greater than on cold days because of the increased use of water for outdoor landscaping. Likewise the demand for electricity in our Big Bear service area is greatly affected by winter snows. An increase in winter snows reduces the use of snow making machines at ski resorts in the Big Bear area and, as a result reduces electric revenues. Variability of weather from normal temperatures or changes in snow or rainfall can materially impact results of operations. As a result, weather has been and will continue to be one of the dominant factors in our financial performance. OUR BUSINESS IS HEAVILY REGULATED AND, AS A RESULT, DECISIONS BY REGULATORY AGENCIES AND CHANGES IN LAWS AND REGULATIONS CAN SIGNIFICANTLY AFFECT OUR BUSINESS. Our revenues depend substantially on the rates that we are permitted to charge our customers and our ability to recover our costs in these rates, including the ability to recover the costs of purchased water, groundwater assessments and electric power costs in rates. In April 1999, the CPUC denied our request to recover through rates the costs associated with our participation in the Coastal Aqueduct Extension of the State Water Project. We also have an application pending before the CPUC to include an additional $1.6 million in rate base for a water treatment plant in SCW's Clearlake service area that was previously disallowed by the CPUC in 1993. In addition, we have an application pending to recover our current energy costs. We have been adversely affected by electric restructuring in California and the escalation of energy costs attributable thereto. The California Department of Water Resources has attempted to alleviate the crisis by purchasing electricity for Pacific Gas and Electric Company, Southern California Edison Company and San Diego Gas and Electric Company, but does not purchase any electricity for our Bear Valley electric division. FERC has taken certain actions intended to stabilize the energy market in the West. These mitigation measures expire on September 30, 2002. Registrant is unable to predict what impact the expiration of these measures will have on electric prices. Cal ISO expects to propose additional market reforms that may substantially increase the costs of SCW. This could have a material adverse impact on SCW if SCW is unable to recover these increased costs from its ratepayers. SCW has filed a complaint with FERC seeking a reduction of the rates in its power purchase contract with Mirant Marketing to a just and reasonable price. Registrant is unable to predict the outcome of this proceeding. SCW has also filed an Advice Letter with the CPUC seeking to recover the costs of its power supply costs previously incurred and expected to be incurred under its contracts with Mirant Marketing and Pinnacle West Capital. SCW has reached a settlement regarding the recovery of a substantial portion of these costs. This settlement has not yet been approved by the CPUC. OUR BUSINESS REQUIRES SIGNIFICANT CAPITAL EXPENDITURES. The utility business is capital intensive. On an annual basis, we spend significant sums for additions to or replacement of property, plant and equipment. During calendar years 2001, 2000 and 1999, we spent $50,253,000, $45,982,000, and $51,578,000, respectively, for these purposes. Our budgeted capital expenditures for calendar year 2002 for these purposes are approximately $56,774,000. We obtain funds for these capital projects from operations, contributions by developers and others and advances from developers (which must be repaid). We also periodically borrow money or issue equity for these purposes. We maintain bank lines of credit that we can use for these purposes. We cannot assure you that these sources will continue to be adequate or that the cost of funds will remain at levels permitting us to remain profitable. ACCOUNTING STANDARDS In July 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards (SFAS) No. 141, "Business Combinations," and SFAS No. 142, "Goodwill and Other Intangible Assets." SFAS No. 141 25

eliminates the pooling-of-interests method of accounting, effective June 30, 2001. After that, all business combinations will be recorded under the purchased method of accounting (record goodwill for excess of costs over the net assets acquired). SFAS No. 142 requires that companies cease amortizing goodwill, effective January 1, 2002. Goodwill initially recognized after June 30, 2001, will not be amortized. Goodwill on the balance sheet at June 30, 2001 will be amortized until January 1, 2002. Under SFAS No. 142, goodwill will be tested for impairment using a fair-value approach when events or circumstances occur indicating that impairment might exist. A benchmark assessment for goodwill is also required within six months of the date of adoption of SFAS No. 142. Registrant has determined that goodwill, $12,285,000 at December 31, 2001, associated with its acquisition of CCWC is not impaired and effective January 1, 2002 has ceased amortizing this goodwill. In 2001, $331,073 was amortized against the goodwill. In June of 2001, the Financial Accounting Standards Board issued SFAS No. 143, "Accounting for Asset Retirement Obligations," on the accounting for obligations associated with the retirement of long-lived assets. SFAS 143 requires a liability to be recognized in the financial statements for retirement obligations meeting specific criteria. SFAS 143 is effective for fiscal years beginning after June 15, 2002. Registrant believes that adoption of this statement will not have a significant impact on its financial position or results of operation. In August 2001, the Financial Accounting Standards Board issued SFAS No. 144 "Accounting for the Impairment or Disposal of Long-Lived Assets". SFAS 144 requires that one accounting model be used for long-lived assets to be disposed of by sale and broadens discontinued operations to include more disposal transactions. Operating losses of discontinued operations are recognized in the period in which they occur, instead of accruing future operating losses before they occur. Registrant is assessing the impact on future financial reporting related to both past and future transactions, but believes that adoption of this statement will not have a significant impact on its financial position or results of operation. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Registrant has no derivative financial instruments, financial instruments with significant off-balance sheet risks or financial instruments with concentrations of credit risk except for the block-forward purchase power contracts that meet the normal purchase exception rule under FASB 133, "Accounting for Derivative Instruments and Hedging Activities." Under the terms of its power purchase contracts with Mirant Marketing and Pinnacle West Capital, SCW is required to post security, at the request of the seller, if SCW is in default under the terms of the contract. For further information, see the section entitled "Contractual Obligations and Other Commitments" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. 26

NOTES TO FINANCIAL STATEMENTS American States Water Company (AWR) is the parent company of Southern California Water Company (SCW), American States Utility Services, Inc. (ASUS) and Chaparral City Water Company (CCWC). SCW is a public utility engaged principally in the purchase, production, distribution and sale of water in California. SCW also distributes electricity in several California mountain communities. The California Public Utilities Commission (CPUC) regulates SCW's water and electric business, including properties, rates, services, facilities and other matters. CCWC is a public utility regulated by the Arizona Corporation Commission (ACC) serving approximately 11,000 customers in the town of Fountain Hills, Arizona and a portion of the City of Scottsdale, Arizona. AWR completed the acquisition of the common stock of CCWC on October 10, 2000 for an aggregate value of $31.2 million, including assumption of approximately $12 million in debt. ASUS performs non-regulated, water related services and operations on a contract basis. There is no direct regulatory oversight by either the CPUC or the ACC of ASUS or AWR. The consolidated financial statements include the accounts of AWR, SCW, ASUS and CCWC. AWR's assets and revenues are primarily those of SCW. NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The consolidated financial statements of AWR include the accounts of AWR and its wholly owned subsidiaries SCW, ASUS and CCWC (collectively referred to as Registrant). Inter-company transactions and balances have been eliminated. The preparation of these financial statements required the use of certain estimates by management in determining Registrant's assets, liabilities, revenues and expenses. The utility subsidiaries, SCW and CCWC, have incurred various costs and received various credits reflected as regulatory assets and liabilities. Accounting for such costs and credits as regulatory assets and liabilities is in accordance with Statement of Financial Accounting Standards No. 71 "Accounting for the Effects of Certain Types of Regulation" (SFAS 71). This statement sets forth the application of generally accepted accounting principles for those companies whose rates are established by or are subject to approval by an independent third-party regulator. Under SFAS 71, utility companies defer costs and credits on the balance sheet as regulatory assets and liabilities when it is probable that those costs and credits will be recognized in the rate making process in a period different from the period in which they would have been reflected in income by an unregulated company. These deferred regulatory assets and liabilities are then reflected in the income statement in the period in which the same amounts are reflected in the rates charged for service. Property and Depreciation: SCW and CCWC capitalize, as utility plant, the cost of additions and replacements of retirement units. Such cost includes labor, material and certain indirect charges. Depreciation is computed on the straight-line, remaining-life basis. For the years 2001, 2000 and 1999 the aggregate provisions for depreciation for SCW approximated 2.6%, 2.6% and 2.5% of the beginning of the year depreciable plant, respectively. The aggregate provision for depreciation for CCWC is 2.5% for each of the same three years. At December 31, 2001, Registrant had $12,285,000 in goodwill included in Other Property and Investments. This amount represents the difference between the purchase price of the common equity of CCWC and CCWC's book equity at the time of closing and was being amortized over a period of 40 years. Pursuant to FASB No. 142, Goodwill and Other Intangible Assets, AWR has concluded that this goodwill is not impaired at December 31, 2001. As a result, amortization of this goodwill will cease effective January 1, 2002. AWR is required to reassess impairment annually. Interest: Interest is generally not capitalized for financial reporting purposes as such procedure is not followed for ratemaking purposes. Revenues: Revenues include amounts billed to customers and unbilled revenues representing estimated amounts to be billed for usage from the last meter reading date to the end of the accounting period. Basic Earnings Per Common Share: Basic Earnings per Common Share are based upon the weighted average number of Common Shares outstanding and net income after deducting preferred dividend requirements. Fully Diluted Earnings Per Common Share: Diluted Earnings Per Common Share are based upon the weighted average number of Common Shares including both outstanding and shares potentially issued in connection with stock options granted under Registrant's 2000 Stock Incentive Plan, and net income after deducting preferred dividend requirements. At December 31, 2001 and 2000, respectively, there were 91,647 and 45,657 options outstanding. 40

Supply Cost Balancing Accounts: As permitted by the CPUC prior to November 29, 2001, Registrant maintained water and electric supply cost balancing accounts for SCW to account for under-collections and over-collections of revenues designed to recover such costs. Costs were recorded in income and charged to balancing accounts when such costs were incurred. The balancing accounts were reversed when such costs were recovered through rate adjustments. Registrant accrued interest on its supply cost balancing accounts at the rate prevailing for 90-day commercial paper. On November 29, 2001, the CPUC issued a resolution ordering that water utilities with existing balancing accounts cease booking amounts into these accounts. In its place, the CPUC required water utilities to start a new memorandum account that would work in a manner similar to the balancing account to track the under-collection or over-collection of supply costs for its water utility service areas. In accordance with this resolution, all supply costs will be accounted for and included in the income statement, just as is the case currently. However, the income statements will not include entries in the income statement reflecting the differences between actual unit supply costs included in rates and those actually experienced by SCW for its water utility service areas. Amounts included in deferred costs (balancing accounts) in the balance sheet will continue to be included in such accounts for SCW's Bear Valley Electric division for recovery at a later date in accordance with the pre-November 29, 2001 procedure applicable to both its water and electric supply balancing accounts. SCW, will not be entitled to recover any deferred costs for its water utility service areas unless (i) the utility is within its general rate case cycle and (ii) it is earning less than its authorized rate of return on a weather normalized means test basis. Registrant does not maintain a supply cost balancing account for CCWC. Debt Issue Expense and Redemption Premiums: Original debt issue expenses are amortized over the lives of the respective issues. Premiums paid on the early redemption of debt, which is reacquired through refunding, are deferred and amortized over the life of the debt issued to finance the refunding. The redemption premium on debt reacquired without refunding is amortized over the remaining period the debt would have been outstanding. Other Credits: Advances for construction represent amounts advanced by developers, which are generally refundable at rates ranging from 10% to 22% of the revenue received from the installations for which funds were advanced or in equal annual installments over periods of time ranging from 10 to 40-year periods. Contributions-in-aid of construction are similar to advances, but require no refunding and are amortized over the useful lives of the related property. For CCWC, advances for construction represents amounts advanced by developers which are refundable over 10 to 20 years. Refund amounts under the contracts are based on annual revenues from the extensions. Cash and Cash Equivalents: For purposes of the Statements of Cash Flows, cash and cash equivalents include short-term cash investments with an original maturity of three months or less. Financial Instrument Risk: Registrant does not carry any financial instruments with off-balance sheet risk nor does its operations result in concentrations of credit risk except for the block-forward purchase power contracts. Under the terms of its power purchase contracts with Mirant Americas Energy Marketing, LP (Mirant Marketing) and Pinnacle West Capital Corporation (Pinnacle West Capital), SCW is required to post security, at the request of the seller, if SCW is in default under the terms of the contract and the future value of the contract is greater than the future value of contracts of a similar term on the date of default. SCW will be in default under the terms of these contracts if its debt is rated less than BBB- by Standard & Poor's Ratings Service ("S&P") or Fitch, Inc. ("Fitch") or less than Baa3 by Moody's Investor Services, Inc ("Moody's"). SCW currently has a rating of A+ by S & P and A2 by Moody's. Fitch does not rate SCW. These block-forward purchase power contracts meet the normal purchase exception rule under FASB No.133, "Accounting for Derivative Instruments and Hedging Activities." Fair Value of Financial Instruments: The table below estimates the fair value of each represented class of financial instrument held by Registrant. For cash and cash equivalents, accounts receivable and short-term debt, the carrying amount is used. Otherwise, rates available to Registrant at December 31, 2001 and 2000 for debt with similar terms and remaining maturities were used to estimate fair value for long-term debt. Changes in the assumptions will produce differing results. 41

The $25 Preferred Shares, 5% Series, are subject to mandatory redemption provisions of 1,600 shares per year. The annual aggregate mandatory redemption requirement for this Series for the five years subsequent to December 31, 2001 is $40,000 each year. AWR intends to redeem or repurchase all of its outstanding Preferred Shares during the first quarter of 2002. AWR has a Registration Statement on file with the SEC for issuance, from time to time, of up to $60 million in Common Shares, Preferred Shares and/or debt securities. On August 16, 2000, AWR issued 1,107,000 shares under this Registration Statement. Net proceeds from this sale were used to fund a portion of the purchase price of CCWC and were invested in SCW. As of December 31, 2001, approximately $31,080,000 remained for issuance under this Registration Statement. For the year ended December 31, 2001 and December 31, 1999, all shares issued under Registrant's Common Share Purchase and Dividend Reinvestment Plan (DRP) and the 401(k) Plan were purchased on the open market. For the year ended December 31, 2000, Registrant issued 6,961 and 7,997 Common Shares under Registrant's DRP and 401(k) Plan, respectively. There are 493,039 and 63,411 Common Shares authorized but unissued under the DRP and the 401(k) Plan, respectively, at December 31, 2001. Shares reserved for the 401(k) Plan are in relation to Company matching contributions and for investment purposes by participants. There are 250,000 Common Shares reserved for issuance under Registrant's "2000 Stock Incentive Plan." Under the Plan, stock options representing, 45,657 and 45,999 Common Shares upon exercise were granted to certain eligible employees on May 1, 2000 and January 2, 2001, respectively. The following table sets forth information with respect to all options granted. The fair value for each option granted was determined on the date of grant using the Black-Scholes model. December 31, 2001 2000 ------------ --------------- -------------- Exercise Price/share $34.81 $31.25 Expiration date January 1, 2011 April 30, 2010 Risk-free rate of return 5.7% 6.5% Dividend yield 4.2% 4.0% Expected volatility 30.5% 28.4% Fair value/share $10.90 $9.89 One-third of the stock options granted become excisable on each of the first three anniversaries of the grant date, but may be exercised earlier if there is a change in control of the Company. No options were exercised at December 31, 2001. SCW and CCWC are subject to contractual restrictions on their ability to pay dividends. Dividends in the amount of $13,530,00 and $12,900,000 were paid by SCW in 2001 and 2000, respectively. Dividends in an amount of $1,003,000 were distributed to AWR in 2001 by CCWC. There were no dividends distributed from CCWC to AWR in 2000. 42

In 1998, the Board of Directors adopted a Shareholder Rights Plan (Rights Plan) and authorized a dividend distribution of one right (a Right) to purchase 1/1000th of Junior Participating Preferred Share for each outstanding Common Share. The Rights Plan became effective in September 1998 and will expire in September 2008. The Rights Plan is designed to provide shareholders' protection and to maximize shareholder value by encouraging a prospective acquirer to negotiate with the board. Each Right represents a right to purchase 1/1000th of Junior Participating Preferred Share at the price of $120, subject to adjustment (the Purchase Price). Each Junior Participating Preferred Share is entitled to receive a dividend equal to 1000 times any dividend paid on each Common Share and 100 votes per share in any shareholder election. The Rights become exercisable upon occurrence of a Distribution Date event. A Distribution Date event occurs if (i) any person accumulates 15% of the then outstanding Common Shares, (ii) any person presents a tender offer which caused the person's ownership level to exceed 15% and the board determines the tender offer not to be fair to AWR's shareholders, or (iii) the board determines that a shareholder maintaining a 15% interest in the Common Shares could have an adverse impact on AWR or could attempt to pressure AWR to repurchase the holder's shares at a premium. Until the occurrence of a Distribution Date, each Right trades with the Common Share and is not separately transferable. When a Distribution Date occurs, AWR would distribute separately Rights Certificates to Common Shareholders and the Rights would subsequently trade separate from the Common Shares and each holder of a Right, other than the acquiring person whose Rights will thereafter be void, will have the right to receive upon exercise at its then current Purchase Price that number of Common Shares having a market value of two times the Purchase Price of the Right. If AWR merges into the acquiring person or enters into any transaction that unfairly favors the acquiring person or disfavors AWR's other shareholders, the Right becomes a right to purchase Common Shares of the acquiring person having market value of two times the Purchase Price. The board of directors may determine that, in certain circumstances, a proposal, which would cause a distribution of the Rights, is in the best interest of AWR's shareholders. Therefore, the board of directors may, at its option, redeem the Rights at a redemption price of $0.01 per Right. NOTE 3 - BANK DEBT AWR maintained a non-revolving credit facility with a $25 million aggregate borrowing capacity in 2001. At December 31, 2001, $20 million was outstanding under this facility. It was subsequently paid off on January 2, 2002. The aggregate short-term borrowing capacity available to SCW under its three bank lines of credit was $47 million as of December 31, 2001, of which no amount was outstanding. There were no compensating balances required. Loans can be obtained at the option of Registrant and bear interest at rates based on floating prime borrowing rates or at money market rates. Registrant's short-term borrowing activities for the last three years were as follows: December 31, (in thousands, except percent) 2001 2000 1999 ------- ------- ------- Balance Outstanding at December 31, $20,000 $45,000 $21,000 Interest Rate at December 31, 2.82% 7.19% 7.35% Average Amount Outstanding $34,748 $38,531 $8,775 Weighted Average Annual Interest Rate 4.65% 7.11% 5.11% Maximum Amount Outstanding $50,000 $50,000 $21,000 ------- ------- ------- There were no short-term borrowing activities at ASUS or CCWC. NOTE 4 - LONG TERM DEBT In January 2001, $20 million of Series C Medium Term Notes were sold with net proceeds from the issuance initially used to repay short-term bank borrowings and, after that, to fund construction expenditures. In 2001 SCW filed a Registration Statement for issuance from time to time of up to $100 million in debt securities. SCW issued $50 million in long-term debt in December 2001. The net proceeds were used to repay short-term bank borrowings, with the remaining proceeds used to refund certain existing long-term debt obligations, and for payments for construction, completion, 43

extension or improvement of facilities. SCW has no mortgage debt, and leases and other similar financial arrangements are not material. CCWC has long-term Industrial Development Authority Bonds (IDA Bonds) and a repayment contract due 2006. Substantially all of the utility plant of CCWC is pledged to secure its IDA Bonds. The Bond Agreement, among other things, (i) requires CCWC to maintain certain financial ratios, and (ii) restricts CCWC's ability to incur additional debt, make liens, sell, lease or dispose of assets, merge with another corporation, and pay dividends. SCW has posted an Irrevocable Letter of Credit, which expires April 30, 2002 in the amount of $2,513,183 with an annual fee of 0.75% as security for its self-insured workers' compensation plan. SCW has also provided an Irrevocable Letter of Credit with a fee of 0.9%, which expires November 15, 2003, in the amount of $6,296,000 to a trustee with respect to the variable rate obligation issued by the Three Valleys Municipal Water District. Additionally, in November 2000, SCW posted an Irrevocable Letter of Credit with an annual fee of 0.65%, which expires in October 1, 2002, in the amount of $250,000 as security for the deductible in the Company's business automobile insurance policy. Annual maturities of all long-term debt, including capitalized leases, amount to $759,867, $13,300,444, $849,286, $903,262 and $662,768 for the five years ending December 31, 2002 through 2006, respectively. NOTE 5 - TAXES ON INCOME Registrant provides deferred income taxes for temporary differences under Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes" (SFAS No. 109), for certain transactions which are recognized for income tax purposes in a period different from that in which they are reported in the financial statements. The most significant items are the tax effects of accelerated depreciation, the supply cost balancing accounts and advances for and contributions-in-aid-of- construction. SFAS No. 109 also requires that rate-regulated enterprises record deferred income taxes for temporary differences accorded flow-through treatment at the direction of a regulatory commission. The resulting deferred tax assets and liabilities are recorded at the expected cash flow to be reflected in future rates. Since the CPUC has consistently permitted the recovery of previously flowed-through tax effects, SCW has established regulatory liabilities and assets offsetting such deferred tax assets and liabilities. Deferred investment tax credits are being amortized to other income ratably over the lives of the property, giving rise to the credits. The significant components of deferred tax assets and deferred tax liabilities, as reflected in the balance sheets, and the accumulated net deferred income tax liabilities at December 31, 2001 and 2000 were: December 31, -------------------------- (dollars in thousands) 2001 2000 ------- ------- Deferred tax assets: Other $14,934 $14,969 -------- -------- 14,934 14,969 -------- -------- Deferred tax liabilities Depreciation (48,064) (46,540) Other property related (8,178) (8,728) Other non-property related (2,666) (4,480) Balancing accounts (9,470) (3,103) -------- -------- (68,378) (62,851) -------- -------- Accumulated deferred income taxes - net $(53,444) $(47,882) -------- -------- 44

The normal retirement benefit is equal to 2% of the five highest consecutive years average earnings multiplied by the number of years of credited service, up to a maximum of 40 years, reduced by a percentage of primary social security benefits. There is also an early retirement option. Annual contributions are made to the Plan, which comply with the funding requirements of the Employee Retirement Income Security Act (ERISA). Registrant also provides all active employees medical, dental and vision care benefits through a medical insurance plan. Eligible employees who retired prior to age 65, and/or their spouses, were able to retain the benefits under the active plan until reaching age 65. Eligible employees upon reaching age 65, and those employees retiring at or after age 65, and/or their spouses, receive coverage through a Medicare supplement insurance policy paid for by Registrant subject to an annual cap limit. The CPUC has issued a decision, which provides for the recovery in rates of tax-deductible contributions made to a separate trust fund. In accordance with that decision, Registrant established two separate trusts in 1995, one for those retirees who were subject to a collective bargaining agreement and another for all other retirees. Registrant's funding policy is to contribute annually an amount at least equal to the revenues authorized to be collected through rates for post-retirement benefit costs. Post-retirement benefit costs for 1993, 1994 and 1995 were estimated at a total of $1.6 million 45

and have been recorded as a regulatory asset for recovery over a 20-year period. The unamortized balance at December 31, 2001 was approximately $452,100. At December 30, 2001, Registrant had 740 participants in the Plan, 74 of these are employees covered by collective bargaining agreements, the earliest of which expires in 2002. The following table sets forth the Plan's funded status and amounts recognized in Registrant's balance sheets and the components of net pension cost and accrued post-retirement liability at December 31, 2001 and 2000: Pension Benefits Other Benefits ------------------ ------------------ (dollars in thousands) 2001 2000 2001 2000 ------- ------- ------ ------ CHANGE IN BENEFIT OBLIGATION: Benefit Obligation at beginning of year $40,521 $35,513 $4,585 $4,431 Service Cost 1,868 1,530 115 103 Interest Cost 2,877 2,649 335 313 Actuarial Loss/(Gain) (81) 2,164 159 (32) Plan Amendment 105 -- -- -- Benefits Paid (1,460) (1,335) (255) (230) ------- ------- ------ ------ Benefit Obligation at end of year $43,830 $40,521 $4,939 $4,585 CHANGES IN PLAN ASSETS: Fair Value of Plan Assets at $45,105 $47,776 $2,058 $1,760 beginning of year Actual Return of Plan Assets (1,641) (1,336) (78) 70 Employer Contributions -- -- 468 458 Benefits Paid (1,460) (1,335) (256) (230) ------- ------- ------ ------ Fair Value of Plan Assets at end of year $42,004 $45,105 $2,192 $2,058 RECONCILIATION OF FUNDED STATUS: Funded Status ($1,826) $4,583 ($2,748) ($2,528) Unrecognized Transition Obligation -- -- 5,449 5,868 Unrecognized Net Loss/(Gain) 2,137 (2,969) (1,218) (1,704) Unrecognized Prior Service Cost 372 311 (2,829) (3,028) ------- ------- ------ ------ Prepaid/(Accrued) Pension Cost $683 $1,925 ($1,345) ($1,392) WEIGHTED-AVERAGE ASSUMPTIONS AS OF DECEMBER 31: Discount Rate 7.25% 7.25% 7.25% 7.25% Long-term Rate of Return 8.00% 8.00% 8.00% 8.00% Salary Assumption 4.00% 4.00% -- -- Medical Cost Trend Rate -- -- 8.50% 6.00% A sliding scale for assumed health care cost increase was used for both periods, starting at 6% in 2000 then remaining at 8.5% in 2001 graded down 1/2 percentage point each year to 5% after 7 years.

1-Percentage- 1-Percentage- (dollars in thousands) Point Increase Point Decrease -------------- -------------- Effect on Total of Service and Interest Cost Components $12 ($10) Effect on Postretirement Benefit Obligation $171 ($152) Registrant has a 401(k) Investment Incentive Program under which employees may invest a percentage of their pay, up to a maximum investment prescribed by law, in an investment program managed by an outside investment manager. Company contributions to the 401(k) are based upon a percentage of individual employee contributions and, for 2001, 2000 and 1999, totaled $953,938, $968,019, and $920,340, respectively. NOTE 7 - BUSINESS RISKS AND COMMITMENTS Registrant's utility operations are engaged in supplying water and electric service to the public. Registrant is required to provide service and grant credit to customers within its defined service areas. Although Registrant has a diversified base of residential, industrial and other customers, revenues derived from commercial and residential water customers accounted for approximately 91% of total water revenues in 2001, which is about the same percentage as in 2000. Registrant faces additional risks associated with weather conditions, adequacy and quality of water supplies, regulatory decisions, pronouncements and laws, water-related litigation, general business conditions and condemnation. Approximately 39.6% of SCW's water supply is purchased from wholesalers of imported water, with the remainder produced from Company wells. The long-term availability of imported water supplies is dependent upon, among other things, drought conditions throughout the state, increases in population, water quality standards and legislation that may potentially reduce water supplies. Reservoir storage statewide is at 95% of normal in January of 2002. The Metropolitan Water District of Southern California has publicly assured consumers that it is well prepared to help the region through one or more dry years. CCWC has a long-term water supply contract with the Central Arizona Water Conservation District through September 2043 and is entitled to take 6,978 acre feet of water per year from the Central Arizona Project (CAP). CCWC's water supply may be subject to interruption or reduction, in particular owing to interruption or reduction of CAP water. In the event of interruption or reduction of CAP water, CCWC can rely on its well water supplies for short-term periods. However, in any event, the quantity of water CCWC supplies to some or all of its customers may be interrupted or curtailed, pursuant to the provisions of its tariffs. For the 2001 water year 6,929,200 AF of water flowed into Lake Powell from the Colorado River, which is only 52% of normal. However the Lake itself is currently at 95% of normal level at the end of 2001. The electric energy environment in California has changed as a result of the December 1995 CPUC decision on restructuring of California's electric utility industry and state legislation passed in 1996. SCW's Bear Valley electric customer service area was exempted by the CPUC from compliance with most of the provisions of the CPUC order and the state legislation. On January 17, 2001, the Governor of the State of California proclaimed a state of emergency in California due to shortages of electricity available to certain of California's utilities (resulting in blackouts), the unanticipated and dramatic increases in electricity prices and the insufficiency of electricity available from certain of California's utilities to prevent disruption of electric service in California. The reasons for the high cost of energy are under investigation but are reported to include, among other things, limited supply caused by a lack of investment in new power plants to meet growth in demand, planned and unplanned outages of power plants, decreased availability of hydroelectric power from the Pacific Northwest due to lower than usual precipitation and higher demand for electricity in the region, transmission line constraints, increased prices for natural gas, the fuel used in many of the power plants serving the region, and a dysfunctional power market. All electric energy sold by SCW to customers in its BVE customer service area is purchased from others. In response to the potential for rising electricity costs, SCW entered into block forward purchase contracts with various parties over time. In March 2001, SCW entered into a five-year, block forward purchase contract with Mirant Americas Energy Marketing, LP (Mirant Marketing) to supply its BVE customer service area with 15 MWs of electric energy at a price of $95 per MWh beginning April 1, 2001 through December 31, 2006. SCW has filed a complaint with the Federal Energy Regulatory Commission seeking to reduce the rates in the Mirant Marketing contract to a just and reasonable price. In June 2001, SCW executed a three-year, block forward purchase agreement with Pinnacle West Capital 47

Corporation for an additional 8 MWs of electric energy to meet BVE's peak winter demands at a price of $75 per MWh for the first year, $48 per MWh for the second year and $36 per MWh for the third year. The average minimum load at SCW's Bear Valley Electric customer service area has been approximately 12 MWs. The average winter load has been 18 MWs with a winter peak of 38 MWs when the snowmaking machines at the ski resorts are operating On February 8, 2002, a settlement agreement among SCW, all intervening parties and the Office of Ratepayer Advocates ("ORA") was filed with the CPUC that will permit SCW to recover $77 per MWh of purchased power costs through rates. SCW will only be allowed to include up to a weighted annual energy purchase cost of $77 per MWh each year for 10 years in its balancing account. To the extent SCW's actual average annual weighted cost for purchased power is less than $77 per MWh, the differential will recover amounts included in the electric supply balancing account. Conversely, to the extent that actual average annual weighted costs for power purchased exceed the $77 per MWh amount, SCW will not be able to include these amounts in its balancing account and such amounts will be expensed against income. SCW has established approximately $7.9 million in reserves as of December 31, 2001 against potential non-recovery of electric power costs. In addition, the settlement extended the previously approved surcharges for an additional five years to allow SCW an opportunity to collect amounts remaining in its electric cost balancing account. The proposed settlement also requires SCW to pursue its complaint filed with FERC in which SCW has requested FERC to reduce the prices in its power purchase contract with Mirant Marketing to just and reasonable prices. A final decision in this matter is expected during the second quarter of 2002. Management believes the CPUC will support the settlement agreement, but is unable to predict when or if the CPUC will authorize recovery of any or all of the costs agreed to in the settlement. For further information, see the sections entitled "Liquidity and Capital Resources" and "Electric Energy Situation in California" included in Part II, Item 7 in Management's Discussion and Analysis of Financial Condition and Results of Operation. Demand for energy in SCW's Bear Valley Electric customer service area generally has been increasing. However, the ability of SCW to deliver purchased power to these customers is limited by the ability of the transmission facilities owned by Southern California Edison Company to transmit this power. In order to meet these increasing energy demands, SCW is considering a number of options including (i) the purchase of electric energy from on-site generation facilities installed by a third party, (ii) the use of portable generation, and (iii) the installation of generation owned by Registrant. Each of these options is expected to result in further increases in electric energy prices for customers of SCW's BVE customer service area. NOTE 8 - CONTINGENCIES SCW has been named as a defendant in twenty lawsuits that allege that SCW and others delivered unsafe water to their customers. Plaintiffs in these actions seek damages, including general, special, and punitive damages, according to proof at trial, as well as attorney's fees on certain causes of action, costs of suit, and other unspecified relief. Seventeen of the lawsuits involve customer service areas located in Los Angeles County in the southern portion of California; three of the lawsuits involve a customer service area located in Sacramento County in northern California. On September 1, 1999, the Court of Appeal in San Francisco held that the CPUC had preemptive jurisdiction over regulated public utilities and ordered dismissal of a series of these lawsuits. On October 11, 1999, one group of plaintiffs appealed the decision to the California Supreme Court. On February 4, 2002, the California Supreme Court concluded that (i) the CPUC had preemptive jurisdiction over claims seeking injunctive relief and claims based on the theory that a public utility regulated by the CPUC provided unsafe drinking water even though it had complied with federal and state drinking water standards, but (ii) the CPUC did not have preemptive jurisdiction over damage claims alleging violations of federal and state drinking water standards by public utilities regulated by the CPUC. As a result, damage claims based on allegations of violations of federal and state drinking water standards may proceed while the other claims must be dismissed. In light of the breadth of plaintiffs' claims, the lack of factual information regarding plaintiffs' claims and injuries, if any, the impact of the California Supreme Court decision on plaintiff's claims and the fact that no discovery has yet been completed, SCW is unable at this time to determine what, if any, potential liability it may have with respect to claims based on allegations of violation of federal and state drinking water standards. On October 25, 1999, SCW filed a lawsuit against the California Regional Water Quality Control Board (CRWQCB) alleging that the CRWQCB has willfully allowed portions of the Sacramento County Groundwater Basin to be injected with chemical pollution that is destroying the underground water supply in SCW's Rancho Cordova customer service area. Management cannot predict the likely outcome of this proceeding. 48

In a separate case, also filed on October 25, 1999, SCW sued Aerojet-General Corporation (Aerojet) for causing the contamination of the Sacramento County Groundwater Basin. On March 22, 2000, Aerojet filed a cross complaint against SCW for negligence and constituting a public nuisance. Registrant is unable to determine at this time what, if any, potential liability it may have with respect to the cross complaint, but intends to vigorously defend itself against these allegations. Management cannot predict the likely outcome of this proceeding. The CPUC has authorized memorandum accounts to allow for recovery of costs incurred by SCW in prosecuting the cases against CRWQCB and Aerojet from customers, less any recovery from the defendants or others. As of December 31, 2001, approximately $6,640,000 has been recorded in the memorandum accounts. The CPUC has authorized SCW to increase rates, effective April 28, 2001, for recovery over a six-year period of approximately $1,800,000, in expenses that were incurred on or before August 31, 2000. SCW will continue to file additional Advice Letters to recover the remaining costs. Management believes these costs are recoverable but cannot give assurance that the CPUC will ultimately allow recovery of all or any of the remaining costs through rates. On April 25, 2001, Registrant filed a lawsuit against all the potentially responsible parties, who stored, transported and dispensed gasoline containing methyl tertiary butyl ether (MTBE) in underground storage tanks, pipelines or other related infrastructure. MTBE contaminated water exists in areas of the basin from which SCW has pumped water through its Charnock Well Field. As a result, SCW ceased operation of its Charnock Well Field in October 1996. Registrant has reached an agreement in this matter that assigns the prosecution of litigation against the potentially responsible parties to the City of Santa Monica, California (Santa Monica). As part of the agreement and in exchange for an assignment payment, Santa Monica will prosecute the case against the potentially responsible parties. Registrant expects that Santa Monica will sign the agreement by the end of the first quarter of 2002. SCW has been, in conjunction with the Southern California Edison (Edison) unit of Edison International, planning to upgrade transmission facilities to 115kv (the 115kv Project) in order to meet increased energy and demand requirements for SCW's Bear Valley Electric Service area. On December 27, 2000, SCW filed a lawsuit against Edison for declaratory relief and seeking damages for breach of contract as a result of delays in the 115kv Project. Subsequently Edison filed a cross-complaint against SCW for breach of contract, anticipatory breach and quantum meruit. Registrant has discussed various settlement options with Edison regarding this matter. However, management cannot predict the likely outcome of either the negotiations or the lawsuits. Under the terms of an energy purchase contract with Dynegy Power Marketing, Inc. (DYPM) that expires on April 30, 2002, DYPM has agreed to provide electric energy to SCW in excess of the amounts it has purchased under the forward block purchase contracts previously described, to sell excess energy purchased by SCW under the terms of these contracts, if requested by SCW, and to act as scheduling coordinator for SCW. However, SCW has entered into a separate agreement for Automated Power Exchange, Inc. to act as its scheduling coordinator and will not utilize the services of DYPM. SCW has withheld payment on $3.4 million invoiced by DYPM for the period December 20, 2000 through February 20, 2001, pending resolution of certain disputes. Most of this amount is included in the electric supply cost balancing account. Based on information available to it, Registrant expects the amount in dispute to increase. Management believes that proper insurance coverage and reserves are in place to insure against property, general liability and workers' compensation claims incurred in the ordinary course of business. NOTE 9 - CONSTRUCTION PROGRAM Registrant's 2002 construction budget provides for gross expenditures of approximately $64.5 million; $8.7 million of this amount is to be obtained from developers and others.

REPORT OF MANAGEMENT The consolidated financial statements contained in the annual report were prepared by the management of American States Water Company, which is responsible for their integrity and objectivity. The consolidated financial statements were prepared in accordance with generally accepted accounting principles and include, where necessary, amounts based upon management's best estimates and judgments. All other financial information in the annual report is consistent with the consolidated financial statements and is also the responsibility of management. Registrant maintains systems of internal control, which are designed to help safeguard, the assets of Registrant and provide reasonable assurance that accounting and financial records can be relied upon to generate accurate financial statements. These systems include the hiring and training of qualified personnel, appropriate segregation of duties, delegation of authority and an internal audit function, which has reporting responsibility to the Audit Committee of the board of directors. The Audit Committee, composed of three outside directors, exercises oversight of management's discharge of its responsibilities regarding the systems of internal control and financial reporting. The committee periodically meets with management, the internal auditor and the independent accountants to review the work and findings of each. The committee also reviews the qualifications of, and recommends to the board of directors, a firm of independent accountants. The independent accountants, Arthur Andersen LLP, have performed an audit of the consolidated financial statements in accordance with generally accepted auditing standards. Their audit gave consideration to Registrant's system of internal accounting control as a basis for establishing the nature, timing and scope of their work. The result of their work is expressed in their Report of Independent Public Accountants. s/ FLOYD E. WICKS s/ McCLELLAN HARRIS III - ------------------ ------------------------ Floyd E.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To the Shareholders and the Board of Directors of American States Water Company: We have audited the accompanying consolidated balance sheets and statements of capitalization of American States Water Company and its subsidiaries, and the balance sheets and statements of capitalization of Southern California Water Company (California corporations), as of December 31, 2001 and 2000, and the related consolidated statements of income, changes in common shareholders' equity and cash flows for each of the three years in the period ended December 31, 2001 of American States Water Company and the related statements of income, changes in common shareholders' equity and cash flows for each of the three years in the period ended December 31, 2001 of Southern California Water Company. These financial statements are the responsibility of the Registrant's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of American States Water Company and its subsidiaries, and Southern California Water Company, as of December 31, 2001 and 2000, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2001 in conformity with accounting principles generally accepted in the United States. /s/ Arthur Andersen LLP - -------------------------- Arthur Andersen LLP Los Angeles, California February 14, 2002 53

AUTOMATED POWER EXCHANGE MASTER TERMS AND CONDITIONS: TAB 1 PARTICIPANT APPROVED COUNTER-PARTY TRADING 1. SCOPE. 1.1. This Tab Number 1 to the APX Master Terms and Conditions of Service sets forth the requirements, procedures, and protocols for the effective use of Participant Approved Counter-Party Trading services. Together with other applicable Tabs, the Master Service and Participation Agreement, and the APX Master Terms and Conditions of Service, all of which are expressly incorporated by reference, this Tab constitutes the entire agreement necessary to conduct Participant Approved Counter-Party Trading in the APX Markets. 1.2. References to a Section shall mean a Section of this Tab 1, unless otherwise agreed. In the event of conflict between this Tab 1 and the APX Master Terms, this Tab 1 shall control and take precedence. The Participant Approved Counter-Party Trading service is an APX Market within the meaning of that defined term. 2. DEFINITIONS. 2.1. The following defined terms supplement the Master Terms and are applicable to Participant Approved Counter-Party Trading in APX Markets in the United States and Canada. 2.1.1. "Delivery" means the actual or required exchange of electricity pursuant to a Contracted Order or otherwise. 2.1.2. "Monthly Invoice" means the APX electronic invoice summarizing a Participant's transactional activity for the month. 3. APPROVED COUNTER-PARTY CONTRACTING. 3.1. APX Participants may Contract in APX Markets via the Market Window on a Participant Approved Counter-Party basis for some or all of their APX Product Specification Sheet requirements, as each Participant may elect. In registering for Participant Approved Counter-Party Trades, a Participant will indicate what counter-party entities that registering Participant is accepting as a trading partner. A Participant may amend its Participant Approved Counter-Party registration statement via the APX Market Window from time to time as it may elect, thereby increasing or decreasing the number of Participant Approved Counter-Parties for that amending Participant. Changes are effective immediately upon receipt by APX. A Participant may also choose to use Participant Approved Counter-Party services solely, or in conjunction with, APX Managed Credit Services as described in Tab 3 to these APX Master Terms. 3.2. Participant Approved Counter-Party Trading must be by the mutual consent of both parties. When mutual consent is indicated to APX, the Participant's Market Window software will be enabled such that only the bids and asks of approved counter-parties may be Contracted, though all Orders from all Participants are viewable. As with APX Managed Credit Services, screen entries by others are anonymous to the Participant until Contracted by the Market Engine. Unlike APX Managed Credit Services, counter-party identity is revealed to each side after Contracting. 3.3. Approved Counter-Party Trading is unsecured and all Participants to such trading expressly agree to the following provisions: a.) each Participant is responsible to itself and the other party for full performance of the Contracted Order, whether entailing obligations to make or take Delivery, or actions to ensure transmission rights affecting Delivery; b.) each Participant is free to alter the terms of the Contracted Order with their Participant Approved Counter-Party after the Contracted Order has been accepted by the Market Engine, in the same manner that they can alter any bilateral obligation; c.) each Participant bears the risk of the other's default in making Delivery or taking Delivery; d.) each Participant remains responsible for informing APX if the Contracted Order or any modification causes a change in APX Scheduling Services, and for payment of all applicable Scheduling fees occasioned thereby; e.) each Participant acknowledges that in any dispute concerning a Participant Approved Counter-Party Contracted Order(s), APX cannot be a Party to the dispute, and can only confirm what the Market Engine recorded as the Contracted Order; and f.) a Participant may not cycle their Participant Approved Counter-Party screen feature on and off as a way of discerning counter-party identity prior to Contracting. The ability to engage in such "toggling" is software limited as discussed in the APX Product Specification Sheet. 3.4. A Participant is permitted to use APX Services in part through Participant Approved Counter-Party Trading as it may elect, and as long as it has at least one Approved Counter-Party. In the event that a Participant shifts to APX Managed Credit Services, triggering collateralization of trades encumbering credit, the provisions of the APX Master Terms and Tab 3 (APX Managed Credit Services) relating to Monetary Reserve Facility procedures apply, and control what actions APX and Participants are required to take. 3.5. A Participant who chooses to use the APX California Scheduling Service (APX SC ID) and/or the APX Qualified Scheduling Entity (QSE) Service must continue to maintain a Monetary Reserve Facility as described in Tab 3 (APX Managed Credit Services) even when they engage in Participant Approved Counterparty Trading. 4. PAYMENT. 4.1. Supplementing the Tab 4 description of APX Market Settlement and Billing processes, the following provisions specific to Participant Approved Counter-Party Trading applies to affected APX Participants: a.) Participant Approved Counter-Party transactions will be recorded and displayed for each Participant within the APX Market Window and the counter-party disclosure report prepared for each Participant. b.) In the event of a Participant Approved Counter-Party default, APX will not act to cure the default or minimize its effects on the parties to the defaulted Order or assure that payment to the non-defaulting party is made. APX' sole responsibility to the parties will be to confirm what the Contracted Order was as recorded by the APX Market Engine. c.) Participants are responsible to APX for the payment of fees associated solely with the amount of Contracted Order energy recorded by the APX Market Engine, regardless of the energy actually delivered and accepted. The Monthly Invoice will display the amount of APX fees owed for all energy transacted, while showing only APX-settled units of energy. 5. ADDENDA. 5.1. Unless expressly addressed, nothing herein shall be construed as a waiver of the Representations and Warranties given by the Parties in Section 4 of the APX Master Terms, or of the Code of Conduct requirements of Section 8 of the APX Master Terms. 5.2. For Participant Approved Counter-Party Trading only, the following Sections of the APX Master Terms and Conditions of Service do not apply: a.) 3.4 requiring that a Monetary Reserve Facility (MRF) be established. b.) Tab 3 to these APX Master Terms addressing APX Managed Credit Services. * * * * * * * * * * * * * * * PAGE 1 OF 1 EFFECTIVE SEPTEMBER 1, 2001

"Monetary Reserve Requirement" means the minimum amount of funds (in US dollars) or reserves (in letter of credit form) that a Participant must maintain in its Monetary Reserve Facility at any given time to cover the Participant's Net Exposure. 2.6. "Net Exposure" means APX' good faith estimate of a Participant's maximum net monetary exposure (in US dollars) relating to the APX Services at any given time, as determined by APX in its reasonable discretion. 2.7. "Net Financial Position" means the total amount (in US dollars) due from or payable to a Participant at any given time, based on the aggregate of such Participant's Contracted Orders and other use of the APX Services. 3. APX MANAGED CREDIT TERMS. 3.1. Each APX Managed Credit Participant shall establish and maintain a Monetary Reserve Facility that meets the requirements set forth in this Tab 3 and is otherwise acceptable to APX in its reasonable discretion. Such Monetary Reserve Facility may take one of the following forms: a. an irrevocable and unconditional letter of credit that has been approved by APX and issued by a bank or other financial institution acceptable to APX in its reasonable discretion, as more fully described below; or b. a cash deposit in an interest-bearing Monetary Reserve Account, with interest accruing to the Participant. 3.2. Each Participant shall establish and maintain its Monetary Reserve Facility in an amount that is sufficient to cover its Net Exposure, as determined by APX from time to time. APX reserves the right to set and modify the criteria used to determine Net Exposure from time to time in its sole reasonable discretion, and will notify Participants of changes in such criteria to the extent that such changes have a material effect upon Participant's Monetary Reserve Requirement. 3.3. Letters of credit are shown as a balance under the "Credit Limit" icon of the Participant's Market Window. APX will provide Participants the templated forms for posting letters of credit. APX will accept letters of credit from financial institutions that enjoy a minimum short-term rating of A1+ (Standard & Poor's), P1 (Moody's), or F1+ (Fitch). If an institution's letter of credit rating falls below the required level after a Participant has Registered, the Participant will be notified and has thirty (30) days from the rating downgrade date to replace the letter of credit. 3.4. Participants may mix Monetary Reserve Facility types to meet their estimated credit limit requirements. In the event of a draw on a Participant's Monetary Reserve Facility where the MRF is comprised of mixed species of funds, APX will exercise its reasonable discretion in drawing on one type before another in curing the deficiency. 3.5. APX shall only initiate a draw upon Participant's Monetary Reserve Facility if it appears there are insufficient funds in the APX Clearing Account on the monthly Payment Due Date to cover that Participant's then presenting Net Exposure. In order to avoid or mitigate this potential situation, APX will monitor a Participant's Net Exposure on a daily basis, and may periodically call for increases in the Participant's posted credit levels in any given month. An inability to post additional credit, or a failure to promptly do so in response to APX' request, will cause the Participant's further trading to be suspended until they unwind their financial position or post additional credit. Under some circumstances, APX may withdraw as the Participant's Scheduling Coordinator and/or Qualified Scheduling Entity, as when a Registered Load has been apprised of the need to increase their available credit, and has failed to do so. Credit is encumbered automatically against entered bids, even before such bids have Contracted on the APX Market Window screen. Bids not Contracted lapse at Market Closing Time, and the unused credit returns to the Participant's then available credit limit. 3.6. Prior to initiating any draw upon a Participant's Monetary Reserve Facility, APX will employ reasonable efforts to notify the Participant of the insufficiency in time for such Participant to rectify the shortage; provided that APX shall not be liable for ( i ) any failure to actually notify a Participant prior to initiating a draw under this Section, or ( ii ) initiating a draw under this Section at any time before, after, or contemporaneously with giving such notice. Each time APX initiates a draw on a Participant's Monetary Reserve Facility, the Participant will incur the Default Fee listed in Tab 5 of these APX Master Terms. 3.7. For Participants that are subject to ISO pass-through charges, it may be necessary to periodically increase a trading Participant's APX Clearing Account cash deposits solely to cover the increased cash exposure in that Page 1 of 2 Effective September 1, 2001

AUTOMATED POWER EXCHANGE MASTER TERMS AND CONDITIONS: TAB 3 APX MANAGED CREDIT SERVICES single trading venue. APX will initiate written notification to the Participant if such an increase in Clearing Account cash deposits is required. For those affected Participants whose trading is ultimately secured by a Monetary Reserve Facility letter of credit, any increase in their APX Clearing Account deposits made necessary by the imposition of ISO pass-through charges must be in the form of cash, rather than in an increase in the face amount of the letter of credit. 3.8. Monetary Reserve Facility cash reserves shall bear interest for the Participant at the rate negotiated from time to time between APX and the Depository. For purposes of the amount to be maintained by the Participant as a Monetary Reserve Facility, the Participant shall receive a credit on the tenth Business Day of each month equal to the amount of interest earned during the preceding calendar month. At a Participant's request, annually in January, APX will distribute to such Participants an amount equal to the interest earned on funds held in the Monetary Reserve Account, so long as such distribution does not cause the Participant to have insufficient credit reserves. * * * * * * * * * * * * * * * * * Page 2 of 2 Effective September 1, 2001

AUTOMATED POWER EXCHANGE MASTER TERMS AND CONDITIONS: TAB 4 SETTLEMENT AND PAYMENT SERVICES 1. SCOPE. 1.1.

"Pass-Through Charges" means all charges and taxes levied by a Control Area Operator or any Governmental Authority (other than APX Fees) in connection with ( i ) the purchase, sale, Delivery, and use of APX Products; or ( ii ) the use of any APX Service. 2.7. "Pass-Through Payments" means all payments from a Control Area Operator, or any other entity, to APX for a Participant in connection with such Participant's use of the APX Services that APX accepts for further pass on to Participants. 2.8.

True-Up Amounts will also be posted in the viewable and downloadable Settlement Statement based upon the data available to APX at the time. If Pass-Through Charges and Pass-Through Payments for that reporting day correlate to more than one APX Participant, APX will allocate such Charges and Payments to affected Participants on a pro rata basis according to the amount of electricity Delivered by or to the Participants in connection with their use of any APX Service. 3.2. Promptly after the end of each calendar month, but no later than the seventh day of the next month, APX will post the Participant's Monthly Invoice reflecting that Participant's Net Financial Position for the prior month. The Monthly Invoice will include all defined elements stated above, and any new or adjusted Control Area Operator Charges or credits received up to the posting date, even if such Charges or credits relate to activity preceding the billing month that is the subject of the Monthly Invoice. 3.3. All Settlement Statements and Monthly Invoices will be delivered via such secure electronic means as may be approved by APX from time to time. Participants desiring delivery of Settlement Statements or Monthly Invoices by means other than the password protected APX Internet Site must make alternate arrangements with APX.

Each Participant that owes money to APX or any other Participant at the end of each month shall deposit such amount, in immediately available funds, into the APX Clearing Account on or before the Payment Due Date. Each Participant is responsible for ensuring that sufficient funds to cover payment for all outstanding liabilities are deposited into the APX Clearing Account on or before the Payment Due Date. 4.2. A Participant's liability for amounts owing to APX or any other entity pursuant to these APX Master Terms at the end of the month shall be discharged to the extent available funds have been deposited by the Participant by the applicable Payment Due Date. If a Participant uses APX Services in more than one APX Market, APX will apply the funds in the Clearing Account to the Participant's outstanding obligations in all APX Markets according to the order in which such obligations were incurred. If sufficient funds have not been deposited in the APX Clearing Account by the Payment Due Date, APX will direct the Depository to allocate the available funds that have been deposited by the Participant in APX' reasonable discretion and will initiate a draw upon the Participant's Monetary Reserve Facility in an amount that is sufficient to discharge remaining obligations. Prior to initiating any such draw, however, APX will employ reasonable efforts to notify the Participant of the insufficiency in time for such Page 1 of 2 Effective September 1, 2001

AUTOMATED POWER EXCHANGE MASTER TERMS AND CONDITIONS: TAB 4 SETTLEMENT AND PAYMENT SERVICES Participant to rectify the shortage; provided that APX shall not be liable for (i) any failure to actually notify a Participant prior to initiating a draw under this Section 4.2, or ( ii ) initiating a draw under this Section 4.2 at any time before, after or contemporaneously with giving such notice. Each time APX initiates a draw on a Participant's Monetary Reserve Facility, the Participant will incur the Default Fee listed in Tab 5 to these APX Master Terms. 4.3. APX shall effectuate payment to each Participant that is owed money at the end of the month by withdrawing the amount due from the APX Clearing Account and depositing such amount into an account designated by the Participant. Any such account must be capable of receiving funds via Fed-Wire. Such payment will occur on the Payment Receipt Date or such other date as may be agreed upon in writing between APX and the Participant. 4.4. APX will remit to each Participant all Pass-Through Payments that are owing to such Participant and that APX has received as of the Payment Due Date. Such remittance will occur on the Payment Receipt Date. In performing this function, APX will forward the Pass-Through Payments actually received, and shall bear no responsibility for any shortage, delay, or reduction in Pass-Through Payment that the originator of the payment may have caused. Participants shall be solely responsible for raising, pursuing and resolving any dispute regarding Pass-Through Payments with the applicable party and/or originator, and shall reimburse APX for any costs incurred by APX in connection therewith. In the event of a dispute between Participant and the originator of Pass-Through Payments, APX' responsibility shall be confined to providing information concerning a Participant's Contracted Orders and Scheduled Deliveries in response to the Participant's reasonable request; provided that the provision of such requested information does not cause or induce a violation or breach of confidentiality arising from obligations under these APX Master Terms. 4.5. In the event a Participant's Net Financial Position has changed between the end of the prior month and the Payment Receipt Date from that of net seller to net buyer as a result of activity in the first 12 days of the new month, APX reserves the right to account for that fact in holding back some of the funds that the Participant would be otherwise entitled to solely as a result of its trading activity in the prior month. 4.6. All exchanges of funds by or with the Depository shall be by Fed-Wire or similarly secure electronic funds transfer method proposed by the Participant and approved by APX. All deposits into the APX Clearing Account and payments from the APX Clearing Account shall be in U.S. dollars.

Notwithstanding the provisions of Section 15 of the APX Master Terms, in the event a Participant disputes any amount in a Settlement Statement or Monthly Invoice, such Participant must notify APX of the Participant's dispute within 30 days after the date of the Statement or Invoice in which the disputed amount first appears. Such notification by a Participant must include a complete statement of the basis underlying the Participant's objection to the amounts set forth in the Settlement Statement or Monthly Invoice. A Participant's failure to notify APX of a Settlement Statement or Monthly Invoice dispute within the relevant 30 day period will constitute acceptance by the Participant of the truth and accuracy of the posted statements and a waiver by the Participant of any right to object to such Settlement Statement or Monthly Invoice. Failure to object to an estimated charge shall not serve to waive or minimize a Participant's right to object to any related True-Up Amount in a subsequent Settlement Statement or Monthly Invoice. Lastly, the Participant is obligated to pay Monthly Invoice published charges, even if disputed, by the Payment Due Date. If the dispute is resolved in the Participant's favor after the Payment Due Date, a credit will be posted to the then current Settlement Statement. 4.8. If APX discovers any error in a Settlement Statement or Monthly Invoice, it will correct such error as soon as practicable. Participants shall be responsible for paying any additional amounts owing to APX, and shall receive payment from APX, as a result of a corrected Settlement Statement or Monthly Invoice in the manner described in Section 4.2 or 4.3 as the case may be. 4.9. Notwithstanding the provisions of Section 3.2, APX may, but is not obligated to, send supplemental invoices to a Participant at any time reflecting True-Up Amounts related to Pass-Through Charges. Payment of amounts set forth in a supplemental invoice shall be due on the date indicated by APX in such invoice. The provisions of this Section 4 shall apply to such supplemental invoices. 4.10. In the event that a Participant has not deposited sufficient funds in the APX Clearing Account by the Payment Due Date, and the Participant's Monetary Reserve Facility is inadequate to cover the shortfall, APX may take any action to recover the unpaid amount that is available to it at law or equity. Interest shall accrue on the unpaid amount until paid in full on a daily basis at a fluctuating rate equal to the highest prime rate published in the Wall Street Journal plus six (6) percent, or the maximum interest rate permitted by law, whichever is less. 4.11. In the event that, as a result of a default by a Participant or otherwise, after reasonable and diligent attempts to replenish the Participant's Clearing Account funds and draw down Participant's Monetary Reserve Facility, APX will act to reduce payments to Participants that are owed money in connection with their use of APX Services in the same APX Market as the defaulting Participant. APX will reduce payments to Participants in that APX Market on an individual basis separate from all other APX Markets, such that payments owed to a Participant in one APX Market will not be reduced to offset unpaid amounts that are owing in connection with APX Services in any other APX Market. * * * * * * * * * * * * * Page 2 of 2 Effective September 1, 2001
