EXCESS-GENERAL LIABILITY POLICY US International Insurance Company Policy #5234125869 National Surety Corporation Policy #XLX1735756 B SUMMARY OF SIGNIFICANT TERMS OF EXISTING POLICIES The following summary is intended to set forth the significant coverage terms of the insurance policies identified in A1 through A5, inclusive, above, and is 9 qualified in its entirety by reference to such policies, true and correct copies of each of which ZCC III acknowledges have been heretofore supplied to it by the Debtor. For convenience, descriptions in the summary below of the significant coverage terms of the "systems performance policies" refer to the aggregate protection afforded under the policies identified in A1, A2(a) and A2(b) above; such references to "property damage and business interruption policy" refer to the protection afforded under policy identified in A3 above; and such references to "general liability insurance policies" refer to the aggregate protection afforded under the policies identified in A4(a) and A5(a) and A5(b) above. Systems Performance Policies The systems performance policies provide combined aggregate coverage of up to $4.5 million per loss occurrence for a declared project of 100 Turbines. The 240 Turbines purchased by the Debtor are included in the first and second projects declared by the Debtor. The 40 remaining Turbines are contained in a third declared project which also covers 60 Turbines owned and operated by Zond Windsystem Partners, Ltd. Series 85-A primary coverage layer of $2.5 million provides protection against revenue losses due to failure to meet projected energy output, and against physical loss or damage to the Turbines due to mechanical or electrical breakdown or defects in materials, design and fabrication. The excess layers provide $2 million of additional protection against physical loss or damage to the Turbines due to mechanical or electrical breakdown or defects in materials, design and fabrication, including lost revenues attributable to such physical loss or damage (but not lost revenues due to wind deficiencies). The systems performance policies do not protect against revenue losses arising out of a failure or a 10 malfunction of the power substation. The revenue protection provided by these policies is designed to substantially cover the Debtor's anticipated debt service payments under the Series B Purchase Notes and the projected necessary operating costs of Turbines so long as such policies remain in effect. The systems performance policies insure each declared project for a term of five years and may not be cancelled by the insurer except for nonpayment of premiums or fraud in the procurement of the policies. The premiums for the systems performance policies are prepaid for the first five years. The Partnership may extend these policies for each declared project for an additional five-year term upon prepayment of the required premiums whose amount depends in part upon the insurers' loss experience in connection with the declared project in question. Reimbursement for losses due to mechanical or electrical breakdown or defects in materials, design and fabrication (including resulting shortfall between projected and actual revenues until damage is repaired or defects are corrected) and costs incurred to investigate, repair or replace suspected defective components is subject to a deductible amount of $1,500 per Turbine per loss occurrence. A loss occurrence is defined as any one loss, disaster or casualty or a series of losses, disasters or casualties arising out of a single event. Coverage under the systems performance policies for losses due to the failure of a declared project to meet projected electric power production due to wind deficiency, or any cause other than those described above or excluded by the policies, is subject to a deductible amount for each loss period equal to 45% of the projected 11 revenues for the first month after which the Turbines contained in a declared project were first placed in service, 40% for the second month after which the Turbines contained in a declared project were first placed in service, 35% for the third month after which the Turbines contained in a declared project were first placed in service and 30% thereafter No loss period is greater than 12 months in duration Revenue losses incurred with respect to any loss period are calculated as the ,shortfall between the projected and actual revenues generated by the insured Turbines from the production of electric power, after adding back the amount of reimbursement for lost revenues payable on account of the causes described in the preceding paragraph. The amount of such shortfall is computed by taking the difference between the minimum projected kilowatt production for the loss period and the actual kilowatt production, and multiplying it by the applicable purchase price under the Power Agreement. The minimum annual projected power production for each declared Project was established by agreement between the Debtor and the insurer at the time of each project declaration. This minimum projected power production amount will be prorated in the case of loss periods shorter than 12 months. The policy allows the insurer, at its cost and expense including reimbursement of any revenue losses incurred by the Debtor due to interruption of Turbine operation), to evaluate and modify the Turbines if they fail to meet the minimum projected power production estimate set forth in the project declaration. Additionally, the policy requires the Debtor to maintain records of wind speed and power production in order to allow accurate loss calculations. The policies require, with respect to each declared project, the repayment to the insurers of amounts paid as reimbursement for revenue shortfall in any loss period from the 12 excess of actual power production revenues over projected power revenues in subsequent loss periods. Premiums due under the policies for the first five years of coverage are calculated at $9,125 per Turbine and are payable when each Turbine is certified to be operational. Upon expiration of the first five years of coverage, the Partnership will be entitled to a return of a portion of the premiums paid with respect to a project if the aggregate amounts paid under the policy with respect to that project do not exceed 60% of such premiums. Premiums for the remaining five years of coverage have not been fixed and will be determined on a project-by-project basis under a formula which is based in part upon the insurers' loss experience under the policies. In addition to the Debtor, Zond, ZCC III, Vestas Energy A/S "Vestas" Vestas North America Limited "VNA") the general partner of the Debtor and Zond Windsystem Partners, Ltd. Series 85-A and its general partner are each named insureds under the policies and are covered thereunder for liability incurred by them by reason of breaches of their warranties to the Partnership relating to the Turbines. Consequently, claims made by such entities under the policies may cause the amount of premium refund to be reduced, and may cause an increase in the amount of any renewal premium. All losses are payable to the Debtor within 30 days after proofs of loss are filed and accepted by the insurer Losses must first be claimed and adjusted under the insurance policy before any warranty claims may be made by the Partnership against Vestas, VNA, ZCC III or Zond. 13 Under the terms of the policy, the insurers are not liable for losses caused by any insured's willful acts performed with the specific intent to cause or aggravate loss to the property; the absence (but not failure) of the components of the Turbine which protect the equipment which control or regulate yawing, vibration, excessive oil temperature and oil levels (the Turbines are equipped with vibration and yaw control equipment but not equipment to regulate oil-temperature and-oil levels); failure to construct, operate and maintain the Turbines in accordance with the procedures or instructions of Zond, Vestas or VNA; normal deterioration of the Turbines; any loss covered under the "All-Risk" property damage and business interruption policy issued by Continental Insurance Company and identified in A3 above; and other common insurance exclusions such as war, governmental or court intervention, nuclear radiation, strikes riots etc Coverage for revenue shortfall contains additional exclusions for revenue losses caused by loss of market price changes not contemplated by the Power Agreement, the inability to sell electricity produced by the Turbines or the abandonment of the Turbines Coverage for damage or physical loss to the Turbines contains additional exclusions for loss or damage caused by frost or freezing, due to disappearance or inventory shortages, or loss or damage caused by any contractor's equipment or the cost to repair or replace the Power Substation Property Damage and Business Interruption Policy The Debtor, along with Zond, Vestas VNA, ZCC III and Zond Windsystem Partners, Ltd Series 85-A, is a named insured under a one-year "All-Risk" property policy covering the Windsystem As is common with such coverage, the insurer 14 may cancel the policy upon 90 days notice except for premium nonpayment, which requires a 10-day notice. The policy-covers all direct physical damage to the Turbines and the power transfer system. It also provides boiler and machinery coverage with business interruption provisions for the power transfer system which insures against losses of income caused by physical damage to the power transfer system or by the inability of Southern California Edison Company ("SCE") to accept power generated by the Turbines. Risks insured against by the policy include fire, wind, hail, freezing, theft, flood and earthquake. The policy contains aggregate combined limits of $40,000,000 per loss occurrence, with an annual aggregate sublimit of $25,000,000 for losses occasioned by either earthquake or flood. The coverage sublimit for boiler and machinery (property damage) on the power transfer system is $2,000,000 per occurrence; for boiler and machinery (business interruption) is $4,000,000 per occurrence; for contingent business interruption is $2,000,000 per occurrence; and for service interruption due to physical damage caused by a peril covered by the policy is $2,000,000 per occurrence. The policy excludes any loss or damage to the Turbines covered by systems performance policies, and contains other commonly specified exclusions such as nuclear radiation, acts of war or civil disobedience, or fraud. The following table summarizes the policy deductibles and coverage limitations and deductible amounts per occurrence: 15 Per Occurrence Coverage Coverage Limits Deductible - -------------------------- ---------------- ----------- Boiler and Machinery $ 2,000,000 $ 5,000 (Property Damage) on Transformers, Feeder Lines and the Power Substation Boiler and Machinery (Business Interruption) 4,000,000 Contingent Business Interruption 2,000,000 All-Risk Property Damage and Business Interruption 40,000,000 1,0002) Property in Transit 500,000 10,0003) Service Interruption 2,000,000 Earthquake 25,000,000(3 Flood 25,000,000(3) 100,000 16 Will not provide coverage for revenue losses occurring during the first 12 hours of each service interruption Per Turbine deductible per loss occurrence, subject to an aggregate per loss occurrence deductible of $10,000. Annual aggregate sublimit. Each earthquake loss occurrence includes all damage occurring during a continuous period of 72 hours Will not provide coverage for revenue losses occurring during the first 48 hours of each service interruption (5) The deductible amount per loss occurrence for each damaged structure is set out in a schedule which is part of the policy. The deductible amount per loss occurrence with respect to each Turbine and its supporting tower is $5,000 and with respect to the Power Substation is $22,140. General Liability Insurance Policies Zond currently maintains a $1,000,000 primary liability insurance policy with the Hartford Insurance Company, identified in A4 above, a $5,000,000 excess general liability policy from 17 US International Insurance Company identified in A5(a) above and an additional $5,000,000 excess policy from the National Surety Corporation identified in A5(b) above The aggregate liability limits will apply to all facilities and operations of named insureds at the Operating Site The Debtor, along with Zond ZCC III and their affiliates, have been named as insureds under the policies The primary policy expires on July 1, 1986 and the excess policies expire on June 1, 1986.

Additional Zond subsidiaries and affiliates and future Zond-sponsored programs, operating at Tehachapi or elsewhere, may also share in such coverage. To the extent that named insureds other than the Debtor perfect claims under the policies, the protection provided to the Debtor may be correspondingly reduced. 18 ANNEX C EXHIBIT E FORM OF SUBORDINATED NOTE ZOND WINDSYSTEM PARTNERS, LTD.
