BASIS OF PRESENTATION The condensed financial statements included herein for the quarterly periods ended March 31, 2006 and 2005 have been prepared by Zond-PanAero Windsystem Partners I, a California Limited Partnership (the "Partnership") without audit pursuant to the rules and regulations of the Securities and Exchange Commission (the "Commission"). Accordingly, these statements reflect all adjustments (consisting only of normal recurring entries), which are, in the opinion of the Partnership, necessary for a fair statement of the financial results for the interim periods. Certain information and notes normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such accounting principals. The Partnership believes that the information and notes included in the financial information are adequate to make the information presented not misleading. Operating results for the interim period presented are not necessarily indicative of the results that may be expected for the year ended December 31, 2006. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. NOTE 2 - THE PARTNERSHIP Introduction The Partnership was formed on June 29, 1984, to purchase, own and operate a system of 300 Vestas Energy A/S Model V-15 wind turbine electric generators (the "Turbines"). The electricity generated by the Turbines is sold by the Partnership to its sole customer, Southern California Edison Company ("SCE"). See Note 8 for additional information. Each Turbine has a rated capacity of 65 kilowatts, and the Turbines have an aggregate rated capacity of 19.5 megawatts. The Turbines, together with certain infrastructural improvements (the "Infrastructural Improvements"), which are owned by Mesa Wind Developers ("Mesa"), a joint venture between Enron Wind Systems, LLC ("EWS") and an affiliate of PanAero Corporation ("PanAero"), form an integrated electric power generating facility (the "Windsystem"). The Windsystem is located in the San Gorgonio Pass area of the San Bernardino Mountains near Palm Springs, California (the "Operating Site"). The Turbines are interconnected by a system of transformers and power transfer lines to a substation and SCE's transmission grid. The individual power lines from each of the Turbines are fed into step-up transformers, which increase the voltage from 480 volts to 12.5 kilovolts. Additional 12.5 kilovolt power transfer lines carry electricity to a substation, which steps up the electric power to 115 kilovolts for delivery to SCE. 7 EWS is an operator of commercial wind-powered electric generating facilities and PanAero is a wind resources development company. On January 3, 1997, EWS's parent, Zond Corporation, became a wholly-owned subsidiary of Enron Renewable Energy Corp., which is wholly-owned by Enron Corp. ("Enron"). In May 1997, the name of Zond Corporation was changed to Enron Wind Corp. ("EWC"). The general partner (the "General Partner") of the Partnership is Zond Windsystems Management LLC ("ZWM"), a California limited liability company wholly-owned by EWS. See "Bankruptcy and Mergers" regarding certain affiliated mergers and name changes affecting ZWM, EWS and EWC. The business of the Partnership and the respective rights of its partners, including the Partnership's limited partners (the "Limited Partners" and together with the General Partner, the "Partners"), are governed by the First Amended and Restated Certificate and Agreement of Limited Partnership of Zond-PanAero Windsystem Partners I, a California Limited Partnership, entered into on November 29, 1984, as amended (the "Partnership Agreement"). The Windsystem, which became operational in November 1984, was constructed by Mesa Construction Company ("MCC"), a joint venture between an affiliate of EWS and an affiliate of PanAero. The Partnership paid MCC a total of $48.9 million for the purchase, construction and installation of the Turbines, comprised of $22.4 million in cash and $26.5 million in the form of eighteen-year, 13% notes payable in equal semi-annual installments of principal and interest totaling $1.9 million (the "Purchase Notes"). In March 2006, the Partnership paid the remaining $0.6 million of interest in arrears due under the Purchase Notes. As a result, the Purchase Notes have been paid in full. See Note 5 below for additional information. Dissolution of the Partnership The term of the Partnership ended on December 31, 2005 in accordance with the provisions of the Partnership Agreement. The Partnership dissolved effective on the day on which the term of the Partnership ended. The General Partner will liquidate the assets of the Partnership, apply and distribute the proceeds thereof as contemplated by the Partnership Agreement, and plans to cause the cancellation of the Partnership's Certificate of Limited Partnership with the Secretary of State of the State of California. The Partnership will then terminate and the General Partner plans to file with the Commission a Form 15 to terminate registration of the Units under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The General Partner is currently evaluating the options in connection with the liquidation of the Partnership's assets. The primary liquidation options that the General Partner is evaluating are (i) the sale of the Turbines to a third party or to Mesa or one of its affiliates and (ii) the abandonment of the Turbines to Mesa under the Wind Park Easement Agreement (as defined in "Substantial Transactions and Operating Agreements" below). In connection with the evaluation of the Turbine sale alternative, the General Partner is reviewing the potential sale of only the Turbines by the Partnership, as well as assessing if the Turbines can be combined for sale with other related assets held by Mesa and PanAero Management Corporation ("PAMC"), a California corporation wholly-owned by PanAero. See Note 8 for additional information. In connection with the evaluation of the Turbine abandonment option, the General Partner has obtained two appraisals of the value of the Turbines from independent third party appraisal companies. The General Partner is continuing the operation of the Windsystem during the liquidation period of the Partnership. The Reservation of Rights Agreement, Wind Park Easement Agreement and Management Agreement (as defined in "Operation and Maintenance Services" and "Substantial Transactions and Operating Agreements" below) each were due to expire on December 31, 2005. The term of each of the Reservation of Rights Agreement and the Wind Park Easement Agreement were extended through March 31, 2006, and the term of the Management Agreement was extended through May 31, 2006. See Note 8 for additional information. 8 Under the terms of the Partnership Agreement, the proceeds of the liquidation of the assets of the Partnership are to be distributed in the following order: (i) first, for the payment of any Partnership liquidation expenses and Partnership debts (other than those owing to any of the Partners), such as the Purchase Notes; (ii) second, for the payment of any Partnership debts owing to any of the Partners; and (iii) third, for distributions to the Partners in proportion to their Partnership adjusted capital accounts, after giving effect to all contributions, distributions and allocations for all taxable years of the Partnership, including the taxable year during which the final liquidating distribution occurs. There is no assurance that, following the payment of the liquidation expenses relating to the Partnership and the payment of the Partnership's debts, there will be any remaining proceeds from the liquidation of the Partnership's assets available for distribution to the Partners. Bankruptcy and Mergers Commencing on December 2, 2001, and periodically thereafter, Enron and certain of its subsidiaries filed voluntary petitions for relief under Chapter 11 of the United States Bankruptcy Code (the "Bankruptcy Code"). This matter is referred to herein as the "Enron Bankruptcy". On February 20, 2002, EWC and Enron Wind Systems, Inc. ("EWSI") each filed a voluntary petition for relief under Chapter 11 of the Bankruptcy Code. Additionally, two California limited liability companies formed on February 19, 2002 for the purposes of merging with EWC and EWSI in anticipation of the sale of Enron's wind turbine manufacturing business also filed voluntary petitions for relief under Chapter 11 of the Bankruptcy Code. EWC merged with and into one of such limited liability companies on April 19, 2002 and the surviving limited liability company changed its name to Enron Wind LLC ("EW"). EWSI merged with and into the other limited liability company, also on April 19, 2002, and the surviving limited liability company changed its name to Enron Wind Systems, LLC. On April 12, 2002, Zond Windsystems Management Corporation ("ZWMC"), the general partner of the Partnership at such time, merged with and into a third California limited liability company, formed on March 12, 2002, and the surviving limited liability company changed its name to Zond Windsystems Management LLC. On May 3, 2002, Zond Construction Corp. merged with and into a fourth California limited liability company, formed on March 21, 2002, and the surviving limited liability company changed its name to Zond Construction LLC ("ZC"). Neither ZWM nor ZC has filed for bankruptcy. On November 17, 2004, the Chapter 11 Plan (the "Plan") relating to the Enron Bankruptcy became effective. The Plan provides for Enron and its affiliated debtor companies (including EWS and EW) to sell most of their assets and distribute to their creditors the proceeds of such sales. In connection with the Plan, EWS assumed the Management Agreement (as defined in "Operation and Maintenance Services" below) and that agreement remains in effect. Substituted Limited Partner PAMC formerly served as a general partner of the Partnership (together with ZWMC, the "Former General Partners"). In June 1988, the Partnership solicited a vote by proxy of the Limited Partners to remove PAMC as a general partner. Pursuant to that vote, PAMC was converted to a substituted limited partner. 9 Although the term "Substituted Limited Partner" is defined in the Partnership Agreement as any individual, partnership, corporation, trust or other entity admitted to the Partnership as a Limited Partner pursuant to transfer provisions under the Partnership Agreement, the term Substituted Limited Partner is used in the accompanying financial statements in reference to the substituted limited partner interest created by the removal of PAMC as a general partner. Under an Agreement of Settlement and Mutual Releases (the "Settlement Agreement") executed on June 26, 2000, PAMC agreed to transfer its substituted limited partner interest in the Partnership to ZWMC. Operation and Maintenance Services EWS manages the Windsystem pursuant to a windsystem management agreement with the Partnership executed on July 27, 1988 (the "Management Agreement"). The Management Agreement by its term was due to terminate on March 31, 2006; however, the Partnership and EWS entered into a Sixth Amendment to Windsystem Management Agreement dated as of March 29, 2006, which extended the termination date of the Management Agreement from March 31, 2006 to May 31, 2006. Prior to May 10, 2002, Enron Wind Maintenance LLC, an affiliate of EWS, provided operations and maintenance services for the Windsystem. On May 10, 2002, EWS contracted with GE Wind Energy, LLC to perform certain operations and maintenance services relating to the Windsystem for a period of one year ending on May 10, 2003. In April 2003, EWS entered into an agreement (the "O&M Agreement") with SeaWest Asset Management Services, LLC ("SeaWest") to provide certain operation and maintenance services relating to the Windsystem for a 5-year period ending on May 10, 2008. If EWS terminates the O&M Agreement prior to the end of its stated term, EWS may be required to pay certain agreed demobilization fees to SeaWest. If EWS is required to pay such fees, EWS may attempt to seek recovery from the Partnership of some, or all, of the amount of such fees pursuant to the terms of the Management Agreement. Management currently estimates that as of March 31, 2006, the amount of the demobilization fee, if any, for which EWS could seek recovery from the Partnership would not be in excess of approximately $50,000. Substantial Transactions and Operating Agreements The accompanying financial statements include substantial transactions with related parties. These transactions are further described in Note 6. A summary of the major operating agreements entered into by the Partnership, directly or indirectly, is set forth below: (1) Through June 23, 2005 the Partnership sold the electricity produced by the Turbines to SCE pursuant to a power purchase and sales agreement (the "Power Agreement") that was originally entered into between SCE and PanAero in April 1982 and covered an aggregate of 29.9 megawatts of generating capacity. PanAero assigned the Power Agreement to Mesa in July 1984. Mesa subsequently assigned the portion of the Power Agreement that covers the aggregate rated capacity of the Turbines (19.5 megawatts) to the Partnership pursuant to that certain Partial Assignment of Wind Park Power Purchase and Sales Agreement dated September 28, 1984 (the "Partial Assignment"). Each of the Partial Assignment and the Power Agreement terminated by its terms on or about June 23, 2005. 10 On or about June 23, 2005, the Partnership and PAMC entered into a Reservation of Rights Agreement dated as of June 23, 2005 (the "Reservation of Rights Agreement") pursuant to which the Partnership is permitted to (i) sell power to SCE from the Windsystem under a Reformed Standard Offer 1 As-Available Capacity and Energy Power Purchase Agreement dated June 23, 2005 between SCE and PAMC (the "RSO1 Power Agreement"), and (ii) interconnect the Windsystem with SCE's transmission system under an Interconnection Facilities Agreement between SCE and PAMC which was effective as of June 23, 2005 (the "Interconnection Agreement"). Under the Reservation of Rights Agreement, the Partnership was permitted and agreed to deliver up to 19.5 megawatts of energy to SCE under the RSO1 Power Agreement and to interconnect the Partnership's Windsystem to SCE's transmission system under the Interconnection Agreement. The Reservation of Rights Agreement was due to terminate on December 31, 2005; however, the Partnership and PAMC, which is an affiliate of Mesa, entered into the Amendment to Reservation of Rights Agreement (the "Reservation of Rights Agreement Amendment") effective as of December 31, 2005, which extended the termination date of the Reservation of Rights Agreement from December 31, 2005 to March 31, 2006. See Note 8 for additional information. The Partnership has not been required under the Reservation of Rights Agreement to pay to PAMC a fee for the Partnership's use of the RSO1 Power Agreement or the Interconnection Agreement. The Partnership has been required to pay for a portion of all fees, costs and expenses incurred by PAMC under the RSO1 Power Agreement and the Interconnection Agreement, including, without limitation, interconnection fees, back feed electricity costs and maintenance costs. The portion of such fees, costs and expenses paid by the Partnership has been based on the ratio of (x) the aggregate installed name-plate capacity of the Partnership's Windsystem to (y) the aggregate installed name-plate capacity of all the wind power projects delivering power to SCE under the RSO1 Power Agreement. PAMC also concurrently entered into a separate reservation of rights agreement with Zond-PanAero Windsystem Partners II, a California limited partnership ("ZWP II") and an affiliate of the Partnership, pursuant to which PAMC granted ZWP II the right to sell to SCE under the RSO1 Power Agreement up to 10.4 megawatts of energy from its wind turbine electric power generation facility and to interconnect such wind power generation facility to SCE's transmission grid under the Interconnection Agreement. Under the RSO1 Power Agreement, SCE is required to purchase from PAMC, and PAMC is required to sell to SCE, the output from the Partnership's Windsystem and ZWP II's wind power facility, provided that the aggregate name-plate capacity of all such generating facilities may not exceed 30 megawatts at any one time. The RSO1 Power Agreement has a five-year term, but may be terminated by PAMC upon 30 days advance notice to SCE. The price to be paid by SCE for the energy delivered under the RSO1 Power Agreement is equal to the short run avoided cost to SCE for energy during the delivery period of such energy. Under the RSO1 Power Agreement, SCE will also pay an annual capacity payment for the installed capacity of such generation facilities that is based on SCE's avoided cost for capacity. Unlike the Power Agreement, which terminated on or about June 23, 2005, the RSO1 Power Agreement does not contain a minimum energy price payable by SCE. The minimum price for energy that was paid by SCE under 11 the Power Agreement was $0.102 per kilowatt hour of energy, and SCE generally paid to the Partnership such minimum price for energy during the term of the Power Agreement. As a result, the price received by the Partnership for the sale of energy under the RSO1 Power Agreement has been, and likely will continue to be more volatile as compared with the price that would have been received by the Partnership under the Power Agreement during the same period of time. (2) Since July 1988, the Partnership has contracted with EWS (or its predecessor) for the operation and maintenance of the Turbines and the performance of certain ancillary management services, such as collection of revenues from SCE and the administration and payment of all Partnership expenses. Under the provisions of the Management Agreement, the Partnership pays a management fee of 2% of the Partnership's gross operating proceeds ("Gross Operating Proceeds"). Gross Operating Proceeds are defined as all gross receipts from the sale of electricity generated by the Turbines and all amounts paid in lieu of receipts from the sale of electricity, including, without limitation, any proceeds of systems performance or wind resource insurance, casualty loss and business interruption insurance paid in reimbursement of lost revenues and warranty payments in reimbursement of lost revenues. Under the Management Agreement, EWS is also reimbursed for 115% of the maintenance costs, including labor and material costs that it incurs in the performance of services, including services performed by third parties. See Note 6 for additional information. The Management Agreement was to terminate by its terms on March 31, 2006; however, the Partnership and EWS entered into a Sixth Amendment to Windsystem Management Agreement dated as of March 29, 2006 which extended the termination date of the Management Agreement from March 31, 2006 to May 31, 2006. (3) The Operating Site is situated on two adjoining parcels of land, consisting of approximately 440 acres, located in the San Gorgonio Pass area of the San Bernardino Mountains approximately 16 miles northwest of Palm Springs, California. The Partnership owns the Turbines, including the supporting towers and related concrete support pads and controllers. The Partnership uses the Infrastructural Improvements and a portion of the Operating Site pursuant to an easement granted by Mesa under the terms of a Wind Park Easement Agreement dated as of September 7, 1984, as amended (the "Wind Park Easement Agreement"). The Infrastructural Improvements include roads, fences, power transfer system, substation and maintenance facilities. Mesa has title to the Infrastructural Improvements, but has granted the Partnership a security interest in such assets under the Wind Park Easement Agreement. The Infrastructural Improvements are also utilized by ZPII under a similar arrangement with Mesa. Mesa has rights to develop wind energy resources at the Operating Site, which includes the Infrastructural Improvements, under a right-of-way grant (the "Right-of-Way Grant") from the United States Bureau of Land Management ("BLM"). The Right-of-Way Grant was originally issued to PanAero on January 26, 1983, and was assigned by PanAero to Mesa in April 1984. The primary term of the Right-of-Way Grant expired on January 26, 2003. On December 19, 2002, the Right-of-Way Grant was extended for a ten-year period commencing on January 27, 2003. Pursuant to the Wind Park Easement Agreement, Mesa granted to the Partnership the right to use a portion of the Operating Site and the Infrastructural Improvements in connection with the operation of the Windsystem. Prior to January 1, 2006, the Wind Park Easement Agreement 12 provided that the royalty payment payable by the Partnership to Mesa equaled 5% of Gross Operating Proceeds, as defined in the Wind Park Easement Agreement (the "Prior Royalty Rate"). The Wind Park Easement Agreement, as previously amended, was due to terminate on December 31, 2005; however, on March 3, 2006, the Partnership and Mesa entered into the Amendment to Wind Park Easement Agreement (the "Easement Agreement Amendment"), which amendment was effective as of December 31, 2005. The Easement Agreement Amendment extended the termination date of the Wind Park Easement Agreement from December 31, 2005 to March 31, 2006. See Note 8 for additional information. The Easement Agreement Amendment also provides that after December 31, 2005, the royalty payment payable by the Partnership to Mesa equals 55% of Net Operating Proceeds, as defined in the Easement Agreement Amendment (the "Current Royalty Rate"). It is expected that for any applicable period after December 31, 2005, the royalty payments payable by the Partnership using the Current Royalty Rate will be substantially higher than if such royalty amounts were calculated using the Prior Royalty Rate. At the termination of the Wind Park Easement Agreement, the Partnership may: (1) elect to abandon the Turbines, with Mesa becoming the owner, (2) at its own expense, remove the Turbines, or (3) elect to sell the Turbines. If the Partnership elects to sell the Turbines at any time, the Partnership must first offer the Turbines to Mesa on the same terms and conditions. If the Partnership abandons the Turbines, neither Mesa nor any affiliate shall have the right to operate the Turbines unless Mesa pays to the Partnership the appraised fair market value (as defined) of the Turbines. If the Partnership does not decide to abandon the Turbines, under the Wind Park Easement Agreement, the Partnership is required to remove the Turbines from the Operating Site on or before May 31, 2006. See Note 8 for additional information. Cash Distributions The Partnership makes cash distributions in accordance with the terms of the Partnership Agreement. Due to less-than-projected operating results, the Partnership has not distributed any cash during any fiscal year other than 1985, in which the Partnership distributed an aggregate of approximately $158,000 to the Limited Partners and $2,000 to the then General Partners. Under the Purchase Notes, the Partnership was not permitted to make cash distributions to its Partners unless certain cash reserve balances were maintained, no events of default existed, and certain ratio tests were met. The Partnership did not meet these criteria at any time since 1985 and did not make any cash distributions to its Partners during the first quarter of 2006. NOTE 3 - GOING CONCERN The following matters raise substantial doubt about the Partnership's ability to continue as a going concern: 1. As discussed in Note 2, the term of the Partnership ended on December 31, 2005. The Partnership dissolved effective on the day on which the term of the Partnership ended. The General Partner is currently evaluating opportunities to liquidate the assets of the Partnership. Upon liquidation of the assets of the Partnership, the General Partner will apply and distribute the proceeds thereof as contemplated by the Partnership Agreement, and plans to cause the cancellation of the Partnership's Certificate of Limited Partnership with the Secretary of State of the State of California. The Partnership will then 13 terminate and the General Partner plans to file with the Commission a Form 15 to terminate registration of the Units under the Exchange Act. 2. As discussed in Note 2, the term of the Reservation of Rights Agreement and the Wind Park Easement Agreement ended on March 31, 2006. The General Partner is seeking to extend the Reservation of Rights Agreement and the Wind Park Easement Agreement. However, if the Partnership cannot obtain extensions of these existing agreements, the Partnership will not have a contractual right to generate power at the Operating Site or to sell any power that it may generate after March 31, 2006, and there is no assurance that the Partnership will receive payment under the RSO1 Power Agreement or otherwise with respect to any deliveries of energy to SCE made after March 31, 2006. See Note 8 for additional information. NOTE 4 - SIGNIFICANT ACCOUNTING POLICIES Basis of Accounting The Partnership's accounting records are maintained on the basis used for federal income tax reporting purposes. For purposes of filing with the Commission, the accounting records have been adjusted to reflect accounting principles generally accepted in the United States of America ("GAAP"). Income Taxes The Partnership is not subject to federal and state income taxes. Accordingly, no recognition has been given to income taxes in the accompanying financial statements since the income or loss of the Partnership is to be included in the tax returns of the individual Partners. The tax returns of the Partnership are subject to examination by federal and state taxing authorities. If such examinations result in adjustments to distributive shares of taxable income or loss, the tax liability of the Partners could be adjusted accordingly. The tax attributes of the Partnership's net assets flow directly to each individual Partner. Individual Partners will have different investment bases depending upon the timing and prices of acquisition of Partnership units. Further, each Partner's tax accounting, which is partially dependent upon their individual tax position, may differ from the accounting followed in the financial statements. Accordingly, there could be significant differences between each individual Partner's tax basis and their proportionate share of the net assets reported in the financial statements. Statement of Financial Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes", requires disclosure by a publicly held partnership of the aggregate difference in the basis of its net assets for financial and tax reporting purposes. However, the Partnership does not have access to information about each individual Partner's tax attributes in the Partnership, and the aggregate tax basis cannot be readily determined. In any event, management does not believe that, in the Partnership's circumstances, the aggregate difference would be meaningful information. Cash Equivalents Cash equivalents are considered to be all highly liquid investments purchased with an original maturity of three months or less. 14 Depreciation The Turbines are recorded at cost. The Turbines were fully depreciated as of December 31, 2004. The Turbines were depreciated on the straight-line method over a twenty-year life. Capitalized improvements and the building are being depreciated on a straight-line method over a fifteen-year life. Expenditures that materially increase the useful lives of assets are capitalized, while ordinary maintenance and repairs are charged to operations as incurred. Replacement of defective parts or expenditures designed to modify Turbines to improve their productivity are expensed as incurred. Earnings Per Limited Partner Unit Earnings per Limited Partner unit are calculated based upon the number of Limited Partner units outstanding during each year. Fair Value of Financial Instruments For each class of financial instruments, including cash and cash equivalents, accounts receivable, prepaid insurance and other current assets, accounts payable and accrued expenses, accounts payable to related party and accrued interest to related party, the carrying amount approximates fair value because of the short maturity of those instruments. Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Electricity Sales and Significant Customer Power generated by the Windsystem is recognized as revenue upon delivery of power to SCE at prices as defined in the RSO1 Power Agreement. All power produced is sold to SCE under the Reservation of Rights Agreement, which term expired on March 31, 2006. See Note 2 and Note 8 for additional information. NOTE 5 - PURCHASE NOTES Under an agreement reached in April 1989, MCC reduced the interest rate on the Purchase Notes from 13% to 11% per annum effective in January 1990. The Partnership secured its payment obligations under the Purchase Notes by granting MCC security interests in the Turbines and other intangible collateral including the rights, title and interests of the Partnership under several of the Partnership's major operating agreements. In March 2006, the Partnership paid the remaining $0.6 million of interest in arrears due under the Purchase Notes. As a result, the Purchase Notes have been paid in full. Prior to the date of the payment of such remaining interest in arrears under the Purchase Notes, the Partnership was in default of the Purchase Notes. During such period and upon notice of default, MCC had a right to foreclose against its security interest in all the assets of the Partnership, including the Turbines. However, MCC did not elect to foreclose on its security interest. 15 NOTE 6 - TRANSACTIONS WITH RELATED PARTIES In addition to the Purchase Notes (See Note 5 above) the Partnership had amounts payable to Mesa and EWS, respectively. Amounts payable to Mesa include easement fees and other miscellaneous expenses related to Windsystem operations. Amounts payable to EWS include management fees, maintenance costs and other miscellaneous expenses related to Windsystem operations. The Partnership has the following related party transactions and relationships: (1) Mesa assigned easement rights to a portion of the Operating Site and granted rights to use the Infrastructural Improvements to the Partnership under the Wind Park Easement Agreement (See Note 2 above). The Partnership incurred $0.17 million in easement fees during the first quarter of 2006 as compared to $0.02 million during the first quarter of 2005 pursuant to the Wind Park Easement Agreement. (2) The Partnership has a contract with EWS to operate and maintain the Turbines and to perform certain management and administrative services under the Management Agreement (See Note 2 above). The Partnership incurred expenses of $0.2 million during each of the first quarters of 2006 and 2005, pursuant to the Management Agreement. In 1988, Mesa assigned $581,000 of receivables from the Partnership to each of its partners, EWSI and an affiliate of PanAero. EWSI subsequently forgave its $581,000 of receivables from the Partnership. This forgiveness was treated as a capital contribution in the accompanying financial statements. NOTE 7 - COMMITMENTS AND CONTINGENCIES Leases Payable None. NOTE 8 - SUBSEQUENT EVENTS Sale of Assets The General Partner is currently in discussions with PAMC and Mesa regarding a potential sale of the Partnership's assets jointly with the Windsystem-related assets held by PAMC and Mesa. In connection with such proposed joint sale, the Partnership, in coordination with Mesa and PAMC, has provided to various potential purchasers information relating to the Turbines and the other assets of the Partnership. Reservation of Rights Agreement To date, the Reservation of Rights Agreement has not been extended beyond March 31, 2006; however, the Partnership has continued to operate the Windsystem and deliver power to SCE. The Partnership is seeking to extend the term of the Reservation of Rights Agreement beyond March 31, 2006. However, there is no assurance that PAMC will grant any such extension. Unless an extension is executed, the Partnership will not have contractual rights to deliver power to SCE under the RSO1 Power Agreement or to interconnect the Partnership's Windsystem with the SCE transmission system, and there is no assurance that the 16 Partnership will receive payment under the RSO1 Power Agreement or otherwise with respect to its deliveries of energy to SCE made after March 31, 2006. Wind Park Easement Agreement To date, the Wind Park Easement Agreement has not been extended beyond March 31, 2006; however, the Partnership has continued to operate the Windsystem on the Operating Site. The Partnership is seeking to extend the term of the Wind Park Easement Agreement beyond March 31, 2006. However, there is no assurance that Mesa will grant any such extension. Unless an extension is executed, the Partnership will not have contractual rights to use a portion of the Operating Site for the production of electricity or to use the Infrastructural Improvements in connection with the operation of the Windsystem after March 31, 2006. The Partnership also is in discussions with Mesa to extend the deadline set forth in the Wind Park Easement Agreement for the removal of the Turbines from the Operating Site beyond May 31, 2006. However, there is no assurance that Mesa will grant any such extension. 17 Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Going Concern The following matters raise substantial doubt about the Partnership's ability to continue as a going concern: 1. As discussed in Note 2 to the Financial Statements, the term of the Partnership ended on December 31, 2005. The Partnership dissolved effective on the day on which the term of the Partnership ended. The General Partner is currently evaluating opportunities to liquidate the assets of the Partnership. Upon liquidation of the assets of the Partnership, the General Partner will apply and distribute the proceeds thereof as contemplated by the Partnership Agreement, and plans to cause the cancellation of the Partnership's Certificate of Limited Partnership with the Secretary of State of the State of California. The Partnership will then terminate and the General Partner plans to file with the Commission a Form 15 to terminate registration of the Units under the Exchange Act. 2. As discussed in Note 2 to the Financial Statements, the term of the Reservation of Rights Agreement and the Wind Park Easement Agreement ended on March 31, 2006. The General Partner is seeking to extend the Reservation of Rights Agreement and the Wind Park Easement Agreement. However, if the Partnership cannot obtain extensions of these existing agreements, the Partnership will not have a contractual right to generate power at the Operating Site or to sell any power that it may generate after March 31, 2006, and there is no assurance that the Partnership will receive payment under the RSO1 Power Agreement or otherwise with respect to any deliveries of energy to SCE made after March 31, 2006. See Note 8 to the Financial Statements for additional information. Liquidity and Capital Resources The Partnership's primary source of revenues and liquidity to fund operations of the Windsystem, repay debt, administer the Partnership, and make distributions to its Partners is the production and sale of electricity from the Windsystem. The Partnership's sole customer is SCE. The price paid by SCE for the electricity is contractually defined under the RSO1 Power Agreement. As of March 31, 2006, the Partnership had no current or planned commitments for capital expenditures. Results of Operations for the Three Months Ended March 31, 2006 Compared to the Three Months Ended March 31, 2005. During the first quarter of 2006, the Partnership's electricity revenue was $0.6 million, and the Windsystem produced 7.9 million kWh of electricity sold to SCE. This was a decrease of $0.04 million or 6% in revenue and an increase of 1.2 million kWh or 18% of electricity produced as compared to the first quarter of 2005. The decrease in electricity revenue was primarily due to the effect of the change in price paid by SCE for the energy delivered by the Partnership. See "Note 2 - THE PARTNERSHIP - Substantial Transactions and Operating Agreements". During the first quarter of 2005, the price paid by SCE for energy delivered by the Partnership was at a rate of $0.102 per kWh. During the first quarter of 2006, SCE paid a price equal to its short-run avoided cost for all energy delivered by the Partnership. During the first quarter of 2006, SCE's short-run avoided cost (and the price paid by SCE for energy delivered by the Partnership 18 during this period) ranged from $0.059 to $0.119 per kWh. Other income remained comparable during the first quarter of 2006 as compared to the first quarter of 2005. Costs and expenses in the first quarter of 2006 were $0.5 million, an increase of $0.2 million or 69%, as compared to the first quarter of 2005. Depreciation remained constant during the first three months of 2006 as compared to the first three months of 2005. Property taxes remained constant during the first quarter of 2006 as compared to the first quarter of 2005. Easement fees increased $.15 million during the first quarter of 2006 as compared to the first quarter of 2005. For the first quarter of 2005, the Wind Park Easement Agreement provided that the easement payment payable by the Partnership to Mesa equals 5% of Gross Operating Proceeds (as defined below). For the first quarter of 2006, the Easement Agreement Amendment provided that the easement payment payable by the Partnership to Mesa equals 55% of Net Operating Proceeds (as defined in the Easement Agreement Amendment). Management fees remained comparable during the first three months of 2006 as compared to the first three months of 2005. Management fees are calculated as a percentage of Gross Operating Proceeds. "Gross Operating Proceeds" are defined as all gross receipts from the sale of electricity generated by the Turbines and all amounts paid in lieu of receipts from the sale of electricity, including, without limitation, any proceeds of systems performance or wind resource insurance, casualty loss and business interruption insurance paid in reimbursement of lost revenues and warranty payments in reimbursement of lost revenues. Maintenance expenses remained constant in the first quarter of 2006 as compared with the first quarter of 2005. Insurance costs decreased by $0.02 million in the first three months of 2006 due to a decrease in renewal rates as compared with the first three months of 2005. Other operating costs increased $0.08 million in the first quarter of 2006 due to an increase in the use of outside consultants as compared to the same period in 2005. Other operating costs for the first quarter of 2005 has a negative balance due to the reversal of audit fees accrued in December 2004. Overall, the Partnership reported net income of $0.1 million for the first quarter of 2006 as compared with net income of $0.4 million for the first quarter of 2005. During the first quarter of 2006, the total partners' capital increased $0.1 million to $0.7 million. The net income per Unit was $109 for the first quarter of 2006 compared with net income per Unit of $318 for the first quarter of 2005. Cash flows from operations increased $0.9 million in the first quarter of 2006 as compared to the first quarter of 2005. This increase was primarily due to a decrease in accrued interest due to related parties during the first quarter of 2006 as compared to the first quarter of 2005. Contractual Obligations The Partnership's contractual obligations as of March 31, 2006 are as follows (in millions): |-------------------------------|--------------------| | | 2006* | |-------------------------------|--------------------| | Purchase obligations: | | |-------------------------------|--------------------| | | | |-------------------------------|--------------------| | Scheduled maintenance fees | $0.139 | |-------------------------------|--------------------| | Demobilization fees | $0.050 | |-------------------------------|--------------------| *The term of the Partnership ended on December 31, 2005; however, the Partnership is operating in liquidation and obtained the right to sell power 19 under the Reservation of Rights Agreement, and extended the term of the Wind Park Easement Agreement, through March 31, 2006, and extended the term of the Management Agreement through May 31, 2006. Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK The Partnership's management with the participation of the General Partners' Chief Executive Officer and Chief Financial Officer has evaluated the disclosure requirements of Item 305 of Regulation S-K "Quantitative and Qualitative Disclosures about Market Risk," and has concluded that the Partnership currently has no market risk sensitive instruments for which this disclosure is required. Item 4. CONTROLS AND PROCEDURES (a) Disclosure Controls and Procedures The term "disclosure controls and procedures" is defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. This term means controls and other procedures of a company that are designed to ensure that information required to be disclosed by the company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company's management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. The Partnership's management, with the participation of the General Partner's Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Partnership's disclosure controls and procedures as of March 31, 2006. Based on these evaluations, the General Partner's Chief Executive Officer and Chief Financial Officer concluded that the Partnership's disclosure controls and procedures were effective as of March 31, 2006. (b) Internal Control Over Financial Reporting During the three months ended March 31, 2006, the Partnership made no change in its internal control over financial reporting (as such term is defined in Rules 13a - 15(f) and 15d - 15(f) under the Exchange Act) that materially affected, or is reasonably likely to materially affect, its internal control over financial reporting. 20 PART II - OTHER INFORMATION Item 3.
