4.      GENERATING FACILITY

        4.1     Ownership

                The Generating Facility shall be owned by Seller.

                4.1.1   If the identity of the Project Manager changes for any
                        reason, Edison shall have the right to approve the new
                        Project Manager. Such approval shall be withheld only if
                        the assets, financial

                                       -9-


                        condition, or operating capability of the proposed
                        replacement Project Manager gives Edison reasonable
                        cause to doubt such entity's ability to adequately
                        perform the duties of the Project Manager. To facilitate
                        such approval, Edison may request Seller to furnish any
                        material reasonably necessary for Edison to prudently
                        approve a change in Project Manager. Therefore, except
                        as in conflict with law, any financing documents,
                        partnership agreements, or management contracts which
                        specify the Project Manager's role shall specifically
                        provide for Edison's right of approval of any such
                        Project Manager. Such change in Project Manager and the
                        approval thereof by Edison shall not operate to reduce
                        the rights and obligations of the project owners under
                        the Contract.

                4.1.2   The Project Manager shall have the authority to contract
                        for the owners of the Project on all matters pertaining
                        to the implementation of this Contract. The Project
                        Manager shall provide Edison with satisfactory evidence
                        of its authority to act on behalf of the owners of the
                        Project. Such evidence shall include, but not be limited
                        to, authenticated copies of any partnership
                        agreement(s), fictitious business name statement(s),
                        certificate(s) of partnership, and management
                        agreement(s). The Project Manager shall also provide
                        Edison with authenticated copies of the

                        any time Seller does not hold such authorizations and
                        permits, Seller agrees to reimburse Edison for any loss
                        which Edison incurs as a result of

                                      -16-


                        the Seller's failure to maintain governmental
                        authorization and permits.

                4.4.14  At Edison's request, Seller shall make all reasonable
                        effort to deliver power at an average rate of delivery
                        at least equal to the Contract Capacity during periods
                        of Emergency. In the event that the Seller has
                        previously scheduled an outage coincident with an
                        Emergency, Seller shall make all reasonable efforts to
                        reschedule the outage. The notification periods listed
                        in Section 4.4.5 shall be waived by Edison if Seller
                        reschedules the outage.

        4.5     Maintenance

                4.5.1   Seller shall maintain the Generating Facility in
                        accordance with applicable California utility industry
                        standards and good engineering and operating practices.
                        Edison shall have the right to monitor such maintenance
                        of the Generating Facility. Seller shall maintain and
                        deliver a maintenance record of the Generating Facility
                        to Edison's Operating Representatives upon request.

                4.5.2   Seller shall make a reasonable effort to schedule
                        routine maintenance during Off-Peak Months. Outages for
                        scheduled maintenance shall not exceed a total of 30
                        peak hours for the Peak Months.

                4.5.3   The allowance for scheduled maintenance is as follows:

                        a.      Outage periods for scheduled maintenance shall
                                not exceed 840 hours (35 days) in any 12-month
                                period. This allowance may

                                      -17-


                                be used in increments of an hour or longer on a
                                consecutive or nonconsecutive basis.

                        b.      Seller may accumulate unused maintenance hours
                                on a year-to-year basis up to a maximum of 1,080
                                hours (45 days). This accrued time must be used
                                consecutively and only for major overhauls.

        4.6     Any review by Edison of the design, construction, operation, or
                maintenance of the Project is solely for the information of
                Edison. By making such review, Edison makes no representation as
                to the economic and technical feasibility, operational
                capability, or reliability of the Project. Seller shall in no
                way represent to any third party that any such review by Edison
                of the Project, including but not limited to, any review of the
                design, construction, operation, or maintenance of the Project
                by Edison is a representation by Edison as to the economic and
                technical feasibility, operational capability, or reliability of
                said facilities. Seller is solely responsible for economic and
                technical feasibility, operational capability, and reliability
                thereof.

5.      OPERATING OPTIONS

        5.1     Seller shall elect in Section 1.9 to Operate its Generating
                Facility in parallel with Edison's electric system pursuant to
                one of the following options:

                a.      Operating Option I: Seller agrees to sell the entire
                        Generator output to Edison with no electrical service
                        required from Edison.

                                      -18-


                b.      Operating Option II: Seller agrees to sell the entire
                        Generator output to Edison with electrical service
                        required from Edison.

                c.      Operating Option III: Seller agrees to sell to Edison
                        only that portion of the Generator output in excess of
                        Seller's electrical service requirements. As much as
                        practicable, Seller intends to serve its electrical
                        requirements from the Generator output and will require
                        electrical standby from Edison as designated in
                        Section 1.9.

        5.2     After expiration of the First Period of the Contract Term,
                Seller may change the Operating Option, but not more than once
                per year upon at least 90 days prior written notice to Edison.
                Edison shall not be required to remove or reserve capacity of
                Interconnection Facilities made idle by a change in operating
                options. Edison may dedicate any such idle Interconnection
                Facilities, owned by Edison, at any time to serve other
                customers or to interconnect with other electric power sources.
                Edison shall process requests for changes of operating option in
                the chronological order received.

                5.2.1   When the Seller wishes to reserve Interconnection
                        Facilities paid for by the Seller but idled by a change
                        in operation option, Edison shall impose a special
                        facilities charge related to the operation and
                        maintenance of the Interconnection Facility. When the
                        Seller no longer needs said facilities for which it has
                        paid, the Seller shall receive credit for the net
                        salvage value of the Interconnection

                                      -19-


                        Facilities dedicated to Edison's use. If Edison is able
                        to make use of these facilities to serve other
                        customers, the Seller shall receive the fair market
                        value of the facilities determined as of the date the
                        Seller either decides no longer to use said facilities
                        or fails to pay the required maintenance fee.

6.      INTERCONNECTION FACILITIES

        6.1     The Parties shall execute an Interconnection Facilities
                Agreement selected by Seller in Section 1.10, covering the
                design, installation, operation and maintenance of the
                Interconnection Facilities required in Edison's sole judgment,
                to permit an electrical interface between the Parties pursuant
                to Edison's Tariff Rule No. 21.

        6.2     The cost for the Interconnection Facilities set forth in the
                appendices specified in Section 1.10, are estimates only for
                Seller's information and will be adjusted to reflect recorded
                costs after installation is complete; except that, upon Seller's
                written request to Edison, Edison shall provide a binding
                estimate which shall be the basis for the Interconnection
                Facilities cost in the Interconnection Facilities Agreement
                executed by the Parties.

        6.3     The nature of the Interconnection Facilities and the Point of
                Interconnection shall be set forth either by equipment lists or
                appropriate one-line diagrams and shall be attached to the
                appropriate appendix specified in Section 1.10.

        6.4     The design, installation, operation, maintenance, and
                modifications of the Interconnection Facilities shall be at
                Seller's expense.

                                      -20-


        6.5     Seller shall not commence parallel operation of the Generating
                Facility until written approval for operation of the
                Interconnection Facilities has been received from Edison. The
                Seller shall notify Edison at least forty-five days prior to the
                initial energizing of the Point of Interconnection. Edison shall
                have the right to inspect the Interconnection Facilities within
                thirty days of receipt of such notice. If the facilities do not
                pass Edison's inspection, Edison shall provide in writing the
                reasons for this failure within five days of the inspection.

        6.6     Seller, at no cost to Edison, shall acquire all permits and
                approvals and complete all environmental impact studies
                necessary for the design, installation, operation, and
                maintenance of the Interconnection Facilities.

7.      ELECTRIC LINES AND ASSOCIATED EASEMENTS

        7.1     Edison shall, as it deems necessary or desirable, build electric
                lines, facilities and other equipment, both overhead and
                underground, on and off Seller's Facility, for the purpose of
                effecting the agreements contained in this Contract. The
                physical location of such electric lines, facilities and other
                equipment on Seller's Facility shall be determined by agreement
                of the Parties.

        7.2     Seller shall reimburse Edison for the cost of acquiring property
                rights off Seller's Facility required by Edison to meet its
                obligations under this Contract.

        7.3     Seller shall grant to Edison, without cost to Edison, and by an
                instrument of conveyance, acceptable to Edison, rights of way,
                easements and other property interests necessary to construct,
                reconstruct, use, maintain, alter,

                                      -21-


                add to, enlarge, repair, replace, inspect and remove, at any
                time, the electric lines, facilities or other equipment, both
                overhead and underground, which are required by Edison to effect
                the agreements contained in the Contract. Seller shall also
                grant the rights of ingress and egress at all reasonable times
                necessary for Edison to perform the activities contemplated in
                the Contract.

        7.4     The electric lines, facilities, or other equipment referred to
                in this Section 7 installed by Edison on or off Seller's
                Facility shall be and remain the property of Edison.

        7.5     Edison shall have no obligation to Seller for any delay or
                cancellation due to inability to acquire a satisfactory right of
                way, easements, or other property interests.

8.      METERING

        8.1     All meters and equipment used for the measurement of electric
                power for determining Edison's payments to Seller pursuant to
                this Contract shall be provided, owned, and maintained by Edison
                at Seller's expense in accordance with Edison's Tariff Rule No.
                21.

        8.2     All meters and equipment used for billing Seller for electric
                service provided to Seller by Edison under Operating Options II
                or III shall be provided, owned, and maintained by Edison at
                Edison's expense in accordance with Edison's Tariff Rule No. 16.

        8.3     The meters and equipment used for measuring the Energy sold to
                Edison shall be located on the side of the Interconnection
                Facilities as specified by Seller in Section 1.13. If the
                metering equipment is located on the Seller's

                                      -22-


                side of the Interconnection Facilities, then a loss compensation
                factor agreed upon by the Parties shall be applied. At the
                written request of the Seller, and at Seller's sole expense,
                Edison shall measure actual transformer losses. If the actual
                measured value differs from the agreed-upon loss compensation
                factor, the actual value shall be applied prospectively. If the
                meters are placed on Edison's side of the Interconnection
                Facilities, service shall be provided at the available
                transformer high-side voltage.

        8.4     For purposes of monitoring the Generator operation and the
                determination of standby charges, Edison shall have the right to
                require, at Seller's expense, the installation of generation
                metering. Edison may also require the installation of
                telemetering equipment at Seller's expense for Generating
                Facilities equal to or greater than 10 MW.

        8.5     Edison's meters shall be sealed and the seals shall be broken
                only when the meters are to be inspected, tested, or adjusted by
                Edison. Seller shall be given reasonable notice of testing and
                have the right to have its Operating Representative present on
                such occasions.

        8.6     Edison's meters installed pursuant to this Contract shall be
                tested by Edison, at Edison's expense, at least once each year
                and at any reasonable time upon request by either Party, at the
                requesting Party's expense. If Seller makes such request, Seller
                shall reimburse said expense to Edison within thirty days after
                presentation of a bill therefor.

                                      -23-


        8.7     Metering equipment found to be inaccurate shall be repaired,
                adjusted, or replaced by Edison such that the metering accuracy
                of said equipment shall be within two percent. If metering

                Energy and Contract Capacity delivered during the period of said
                inaccuracy shall be estimated by Edison and agreed upon by the
                Parties.

9.      POWER PURCHASE PROVISIONS

        Prior to the date of Firm Operation, Seller shall be paid for Energy
        only pursuant to Edison's published avoided cost of energy based on
        Edison's full avoided operating cost as periodically updated and
        accepted by the Commission. If at any time Energy can be delivered to
        Edison and Seller is contesting the claimed jurisdiction of any entity
        which has not issued a license or other approval for the Project,
        Seller, in its sole discretion and risk, may deliver Energy to Edison
        and, for any Energy purchased by Edison, Seller shall receive payment
        from Edison for (i) Energy pursuant to this Section, and (ii)
        as-available capacity based on a capacity price from the Standard Offer
        No. 1 Capacity Payment Schedule as approved by the Commission. Unless
        and until all required licenses and approvals have been obtained, Seller
        may discontinue deliveries at any time.

        9.1     Capacity Payments

                Seller shall sell to Edison and Edison shall purchase from
                Seller capacity pursuant to the capacity payment option selected
                by Seller in Section 1.11. The Capacity Payment Schedules will
                be based on Edison's full avoided operating costs as approved by
                the Commission throughout the life of this

                                      -24-


                Contract. Data used to derive Edison's full avoided costs will
                be made available to the Seller, to the extent specified by
                Seller upon request.

                9.1.1   Capacity Payment Option A - As Available Capacity.
                        Seller shall be paid a monthly capacity payment
                        calculated pursuant to the following formula;

        Monthly Capacity Payment =  (A x D) + (B x D) + (C x D)

                        Where A  =  kWh purchased by Edison during on-peak
                                    periods defined in Edison's Tariff Schedule
                                    No. TOU-8.

                              B  =  kWh purchased by Edison during mid-peak
                                    periods defined in Edison's Tariff Schedule
                                    No. TOU-8.

                              C  =  kWh purchased by Edison during off-peak
                                    periods defined in Edison's Tariff Schedule
                                    No. TOU-8.

                              D  =  The appropriate time differentiated capacity
                                    price from the Forecast of Annual
                                    As-Available Capacity Payment Schedule as
                                    specified by Seller in Section 1.11.

                        9.1.1.1     The formula set forth in Section 9.1.1
                                    shall be computed as follows:

                                    a.  During the First Period of the Contract
                                        Term D shall equal the appropriate time
                                        differentiated capacity price from the
                                        Forecast of Annual As-Available Capacity
                                        Payment Schedule.

                                    b.  During the Second Period of the Contract
                                        Term, the formula shall be computed with
                                        D equal to the

                                      -25-


                                        appropriate time differentiated capacity

                                    Marginal Cost of Energy, multiplied by the
                                    decimal equivalent of the percentage of the
                                    forecast specified in Section 1,12, and
                                    (ii)the appropriate time differentiated
                                    energy price from Edison's published avoided
                                    cost of energy multiplied by the decimal
                                    equivalent of the percentage of the
                                    published energy price specified in
                                    Section 1.12.

                9.2.2   Energy Payment Option 2 - Levelized Forecast of Marginal
                        Cost of Energy.

                        If Seller selects energy payment option 2, then during
                        the First Period of the Contract Term, Seller shall be
                        paid a monthly energy payment for Energy delivered by
                        Seller and purchased by Edison each month during the
                        First Period of the Contract Term pursuant to the

                                    No. TOU-8.

                              D  =  The sum of:

                                    (i) the appropriate time differentiated
                                    energy price from the Levelized Forecast of
                                    Marginal Cost of Energy, for the First
                                    Period of the Contract Term multiplied by
                                    the decimal equivalent of the percentage of
                                    the levelized forecast specified in Section
                                    1.12, and (ii) the appropriate time
                                    differentiated energy price from Edison's
                                    published avoided cost of energy multiplied
                                    by the decimal equivalent of the percentage
                                    of the published energy price specified in
                                    Section 1.12.

                        9.2.2.2     Performance Requirement for Energy Payment
                                    Option 2

                                    During the First Period when the annual
                                    forecast referred to in Section 9.2.1 is
                                    greater than the levelized forecast referred
                                    to in Section 9.2.2, Seller shall deliver to
                                    Edison at least 70 percent of the average
                                    annual kWh

                                      -28-


                                    delivered to Edison during those previous
                                    periods when the levelized forecast referred
                                    to in Section 9.2.2 is greater than the
                                    annual forecast referred to in Section 9.2.1
                                    as resource conditions permit for solar,
                                    wind, and hydro Generating Facilities and
                                    excluding uncontrollable forces. If Seller
                                    does not meet the performance requirements
                                    of this Section 9.2.2.1, Seller shall be
                                    subject to Section 9.5.

        9.3     Energy Payments - Second Period

                During the Second Period of the Contract Term, Seller shall be
                paid a monthly energy payment for Energy delivered by Seller and
                purchased by Edison at a rate equal to 100% of Edison's
                published avoided cost of energy based on Edison's full avoided
                operating cost as updated periodically and accepted by the
                Commission, pursuant to the following formula:

         monthly energy payment  =  kWh purchased by Edison for each on-peak,
                                    mid-peak, and off-peak time period defined
                                    in Edison's Tariff Schedule No. TOU-8

                                 x  Edison's published avoided cost of energy
                                    by time of delivery for each time period.

                Data used to derive Edison's full avoided costs will be made
                available to the Seller, to the extent specified by Seller, upon
                request.

                                      -29-


        9.4     Edison shall not be obligated to accept or pay for Energy, and
                may request Seller whose Generating Facility is one (1) MW or
                greater to discontinue or reduce delivery of Energy, for not
                more than 300 hours annually during off-peak hours when (i)
                purchases would result in costs greater than those which Edison
                would incur if it did not purchase Energy from Seller but
                instead utilized an equivalent amount of Energy generated from
                another Edison source, or (ii) the Edison Electric System demand
                would require that Edison hydro-energy be spilled to reduce
                generation.

        9.5     Energy Payment Refund

                If Seller elects energy payment option 2, Seller shall be
                subject to the following:

                9.5.1   If Seller fails to perform the Contract obligations for
                        any reason during the First Period of the Contract Term,
                        or fails to meet the performance requirements set forth
                        in Section 9.2.2.1, and at the time of such failure to
                        perform, the net present value of the cumulative Energy
                        payments received by Seller pursuant to energy payment
                        option 2 exceeds the net present value of what Seller
                        would have been paid pursuant to energy payment option
                        1, Seller shall make an energy payment refund equal to
                        the difference in such net present values in the year in
                        which the refund is due. The present value calculation
                        shall be based upon the rate of Edison's incremental
                        cost of capital specified in Section 1.12.

                                      -30-


                9.5.2   Not less than 90 days prior to the date Energy is first
                        delivered to the Point of Interconnection, Seller shall
                        provide and maintain a performance bond, surety bond,
                        performance insurance, corporate guarantee, or bank
                        letter of credit, satisfactory to Edison, which shall
                        insure payment to Edison of the energy payment refund at
                        any time during the First Period. Edison may, in its
                        sole discretion accept another form of security except
                        that in such instance a 1-1/2 percent reduction shall
                        then apply to the levelized forecast referred to in
                        Section 9.2.2 in computing payments for Energy. Edison
                        shall be provided with certificates evidencing Seller's
                        compliance with the security requirements in this
                        Section which shall also include the requirement that
                        Edison be given 90 days prior written notice of the
                        expiration of such security.

                9.5.3   If Seller fails to provide replacement security not less
                        than 60 days prior to the date of expiration of existing
                        security, the energy payment refund provided in
                        Section 9.5 shall be payable forthwith. Thereafter,
                        payments for Energy shall be 100 percent of the monthly
                        energy payment provided in Section 9.2.1.

                9.5.4   If Edison at any time determines the security to be
                        otherwise inadequate, and so notifies Seller, payments
                        thereafter for Energy shall be 100 percent of the
                        monthly energy payment provided in Section 9.2.1. If
                        within 30 days of the date Edison gives notice of such
                        inadequacies, Seller satisfies Edison's security
                        requirements,

                                      -31-


                        energy payment option 2 shall be reinstated. If Seller
                        fails to satisfy Edison's security requirements within
                        the 30-day period, the energy payment refund provided in
                        Section 9.5 shall be payable forthwith.

10.     PAYMENT AND BILLING PROVISIONS

        10.1    For Energy and capacity purchased by Edison:

                10.1.1  Edison shall mail to Seller not later than thirty days
                        after the end of each monthly billing period (1) a
                        statement showing the Energy and Contract Capacity
                        delivered to Edison during the on-peak, mid-peak, and
                        off-peak periods, as those periods are specified in
                        Edison's Tariff Schedule No. TOU-8 for that monthly
                        billing period, (2) Edison's computation of the amount
                        due Seller, and (3) Edison's check in payment of said
                        amount.

                10.1.2  If the monthly payment period involves portions of two
                        different published Energy payment schedule periods, the
                        monthly Energy payment shall be prorated on the basis of
                        the percentage of days at each price.

                10.1.3  If the payment period is less than 27 days or greater
                        than 33 days, the capacity payment shall be prorated on
                        the basis of the average days per month per year.

                10.1.4  If within thirty days of receipt of the statement Seller
                        does not make a report in writing to Edison of an error,
                        Seller shall be deemed to have waived any error in
                        Edison's statement,

                                      -32-


                        computation, and payment, and they shall be considered

                        10.2.1.1    (Applicable to SCG-1 only) The Standby
                                    Demand for calculation of the standby charge

                                    reserves the right to adjust the Standby
                                    Demand based on recorded demand during
                                    periods standby power is required.

                        10.2.1.2    (Applicable to SCG-I only) The capacity
                                    rating for determination of standby waiver

                                    Generating Facility during the on-peak time
                                    period recorded during the preceding
                                    12-month time period.

                        10.2.1.3    A minimum monthly charge may be established
                                    for standby electric service as provided in
                                    the tariff schedule elected in Section 1.9.
                                    Said minimum monthly charge shall be
                                    specified in Section 1.9.

                10.2.2  Under Operating Options II and III pursuant to Section
                        5.1, electric service shall be provided under terms,
                        conditions, and rates of Edison's tariff schedule

                        authorized by the Commission to be revised. The
                        applicable tariff schedule is:

                                    TOU-8, GS-1 or
                                    GS-2

                        The contract demand for calculation of the minimum
                        demand charge in the applicable tariff schedules is
                        specified in Section 1.9.

                10.2.3  Edison shall commence billing Seller for electric
                        service rendered pursuant to the applicable tariff
                        schedule on the date that the Point of Interconnection
                        is energized.

        10.3    Monthly charges associated with Interconnection Facilities shall
                be billed pursuant to the Interconnection Facilities Agreement
                contained in the Appendix specified in Section 1.10.

        10.4    Energy Payment Refund

                                      -34-


11.     TAXES

        11.1    Seller shall pay ad valorem taxes and other taxes properly
                attributable to the Project. If such taxes are assessed or

                assessment or levy.

        11.2    Seller shall pay ad valorem taxes and other taxes properly

        11.3    Edison shall pay ad valorem taxes and other taxes properly
                attributed to Interconnection Facilities they own. If such taxes
                are assessed or levied against Seller, Edison shall pay Seller
                for such assessment or levy.

        11.4    Seller or Edison shall provide information concerning the
                Project to any requesting taxing authority.

                within 5 years of the date of Contract execution.

13.     LIABILITY

        13.1    Each Party (First Party) releases the other Party (Second
                Party), its directors, officers, employees and agents from any
                loss, damage, claim, cost, charge, or expense of any kind or
                nature (including any direct, indirect or consequential loss,
                damage, claim, cost, charge, or expense), including attorneys'
                fees and other costs of litigation, incurred by the First Party
                in connection with damage to property of the First Party caused
                by or arising out of the Second Party's construction,
                engineering, repair,

                                      -35-


                supervision, inspection, testing, protection, operation,
                maintenance, replacement, reconstruction, use or ownership of
                its facilities, to the extent that such loss, damage, claim,
                cost, charge, or expense is caused by the negligence of Second
                Party, its directors, officers, employees, agents, or any person
                or entity whose negligence would be imputed to Second Party.

        13.2    Each Party shall indemnify and hold harmless the other Party,
                its directors, officers, and employees or agents from and
                against any loss, damage, claim, cost, charge, or expense of any
                kind or nature (including direct, indirect or consequential
                loss, damage, claim, cost, charge, or expense), including
                attorneys' fees and other costs of litigation, incurred by the
                other Party in connection with the injury to or death of any
                person or damage to property of a third party arising out of the
                indemnifying Party's construction, engineering, repair,
                supervision, inspection, testing, protection, operation,
                maintenance, replacement, reconstruction, use, or ownership of
                its facilities, to the extent that such loss, damage, claim,
                cost, charge, or expense is caused by the negligence of the
                indemnifying Party, its directors, officers, employees, agents,
                or any person or entity whose negligence would be imputed to the
                indemnifying Party; provided, however, that each Party shall be
                solely responsible for and shall bear all cost of claims brought
                by its contractors or its own employees and shall indemnify and
                hold harmless the other Party for any such costs including costs
                arising out of any workers compensation law. Seller releases and
                shall defend and indemnify Edison from any claim, cost, loss,
                damage, or

                                      -36-


                liability arising from any contrary representation concerning
                the effect of Edison's review of the design, construction,
                operation, or maintenance of the Project.

        13.3    The provisions of this Section 13 shall not be construed so as
                to relieve any insurer of its obligations to pay any insurance
                claims in accordance with the provisions of any valid insurance
                policy.

        13.4    Neither Party shall be indemnified under this Section 13 for its
                liability or loss resulting from its sole negligence or willful
                misconduct.

14.     INSURANCE

        14.1    Until Contract is terminated, Seller shall obtain and maintain
                in force as hereinafter provided comprehensive general liability
                insurance, including contractual liability coverage, with a
                combined single limit of not less than $1,000,000 each
                occurrence. The insurance carrier or carriers and form of policy
                shall be subject to review and approval by Edison.

        14.2    Prior to the date Seller's Generating Facility is first operated
                in parallel with Edison's electric system, Seller shall (i)
                furnish certificate of insurance to Edison, which certificate
                shall provide that such insurance shall not be terminated nor
                expire except on thirty days prior written notice to Edison,
                (ii) maintain such insurance in effect for so long as Seller's
                Generating Facility is operated in parallel with Edison's
                electric system, and (iii) furnish to Edison an additional
                insured endorsement with respect to such insurance in
                substantially the following form:

                        "In consideration of the premium charged, Southern
                        California Edison Company (Edison) is named as
                        additional insured with

                                      -37-


                        respect to all liabilities arising out of Seller's use
                        and ownership of Seller's Generating Facility. "The
                        inclusion of more than one insured under this policy
                        shall not operate to impair the rights of one insured
                        against another insured and the coverages afforded by
                        this policy will apply as though separate policies had
                        been issued to each insured. The inclusion of more than
                        one insured will not, however, operate to increase the
                        limit of the carrier's liability. Edison will not, by
                        reason of its inclusion under this policy, incur
                        liability to the insurance carrier for payment of
                        premium for this policy.

                        "Any other insurance carried by Edison which may be
                        applicable shall be deemed excess insurance and Seller's
                        insurance primary for all purposes despite any
                        conflicting provisions in Seller's policy to the
                        contrary."

                If the requirement of Section 14.2(iii) prevents Seller from
                obtaining the insurance required in Section 14.1, then upon
                written notification by Seller to Edison Section 14.2(iii) shall
                be waived.

        14.3    The requirements of this Section 14 shall not apply to Seller
                who is a self-insured governmental agency with established
                record of self-insurance.

        14.4    If Seller fails to comply with the provisions of this Section
                14, Seller shall, at its own cost, defend, indemnify, and hold
                harmless Edison, its directors, officers, employees, agents,
                assigns, and successors in interest from and against any and all
                loss, damage, claim, cost, charge, or expense of any

                                      -38-


                kind or nature (including direct, indirect or consequential
                loss, damage, claim, cost, charge, or expense, including
                attorneys' fees and other costs of litigation) resulting from
                the death or injury to any person or damage to any property,
                including the personnel and property of Edison, to the extent
                that Edison would have been protected had Seller complied with
                all of the provisions of this Section 14.

15.     UNCONTROLLABLE FORCES

        15.1    Neither Party shall be considered to be in default in the
                performance of any of the agreements contained in this Contract,
                except for obligations to pay money, when and to the extent
                failure of performance shall be caused by an Uncontrollable
                Force.

        15.2    If either Party because of an Uncontrollable Force is rendered
                wholly or partly unable to perform its obligations under this
                Contract, the Party shall be excused from whatever performance
                is affected by the Uncontrollable Force to the extent so
                affected provided that:

                (1)     the nonperforming Party, within two weeks after the
                        occurrence of the Uncontrollable Force, gives the other
                        Party written notice describing the particulars of the
                        occurrence,

                (2)     the suspension of performance is of no greater scope and
                        of no longer duration than is required by the
                        Uncontrollable Force,

                (3)     the nonperforming Party uses its best efforts to remedy
                        its inability to perform (this subsection shall not
                        require the settlement of any strike, walkout, lockout
                        or other labor dispute on terms which, in the sole
                        judgment of the Party involved in the dispute, are
                        contrary

                                      -39-


                        to its interest. It is understood and agreed that the
                        settlement of strikes, walkouts, lockouts or other labor
                        disputes shall be at the sole discretion of the Party
                        having the difficulty.

                (4)     when the nonperforming Party is able to resume
                        performance of its obligations under this Contract, that
                        Party shall give the other Party written notice to that
                        effect.

        15.3    In the event that either Party's ability to perform cannot be
                corrected when the Uncontrollable Force is caused by the actions
                or inactions of legislative, judicial or regulatory agencies or
                other proper authority, this Contract may be amended to comply
                with the legal or regulatory change which caused the
                nonperformance. If a loss of Qualifying Facility status occurs
                due to an Uncontrollable Force and Seller fails to make the
                changes necessary to maintain its Qualifying Facility status,
                the Seller shall compensate Edison for any economic detriment
                incurred by Edison as a result of such failure.

16.     NONDEDICATION OF FACILITIES

        Neither Party, by this Contract, dedicates any part of its facilities
        involved in this Project to the public or to the service provided under
        the Contract, and such service shall cease upon termination of the
        Contract.

17.     PRIORITY OF DOCUMENTS

        If there is a conflict between this document and any Appendix, the
        provisions of this document shall govern.

        Each Party shall notify the other immediately upon the determination of
        the existence of any such conflict.

                                      -40-

20.     NONWAIVER

        either Edison or Seller to insist in any one or more instances upon
        strict performance of any of the provisions of the Contract or to take
        advantage of any of its rights hereunder shall not be construed as a
        waiver of any such provisions or the relinquishment of any

                                      -41-


        such rights for the future, but the same shall continue to remain in
        full force and effect.

        duties under this Contract, or any part of such rights or duties,
        without the written consent of the other Party, except in connection

                                   APPENDIX A

         INTERCONNECTION FACILITIES - SELLER OWNED AND OPERATED FACILITY

A.l     Seller shall design, purchase, construct, operate and maintain Seller
        owned Interconnection Facilities at its sole expense. Edison shall have
        the right to review the design as to the adequacy of the Protective
        Apparatus provided. Any additions or modifications required by Edison
        shall be incorporated by Seller.

A.2     Notwithstanding the provisions of Section 13, Seller, having elected to
        own, operate, and maintain the Interconnection Facilities, shall accept
        all liability and release Edison from and indemnify Edison against any
        liability for faults or damage to Seller's Interconnection Facility, the
        Edison electric system and the public as a result of the operation of
        Seller's project, except that Edison shall not be indemnified for its
        liability or loss resulting from its sole negligence or willful
        misconduct.

A.3     Edison shall have the right to observe the construction of the
        Interconnection Facilities, and inspect said facilities after
        construction is completed at the Seller's expense.

A.4     Facilities which are deemed necessary by Edison for the proper and safe
        operation of the Interconnection Facilities and which Seller desires
        Edison to own and operate at Seller's expense shall be provided as
        appendant facilities. Edison shall own, operate and maintain any
        necessary appendant facilities which may be installed in connection with
        the Interconnection Facilities at Seller's expense. Edison may, as it
        deems necessary, modify the aforementioned facilities at Seller's

        Interconnection Facilities Plus Operation and Maintenance.

A.7     To the extent that Edison deems it necessary to effect the arrangements
        contemplated by this Agreement, Edison may, from time to time, request
        the Seller to design, install, operate, maintain, modify, replace,
        repair or remove any or all of the Interconnection Facility. Such
        equipment and/or Protective Apparatus shall be treated as
        Interconnection Facilities and added to the Interconnection Facilities
        Contract by amendment pursuant to Section A.4.

A.8     Edison shall have the right to review any changes in the design of the
        Interconnection Facilities and recommend modification(s) to the design
        as it deems necessary for proper and safe operation of the Project when
        in parallel with the Edison electric system.

                                                        ------------------------


             APPLICATION AND CONTRACT FOR INTERCONNECTION FACILITIES
                         PLUS OPERATION AND MAINTENANCE

        The Seller hereby requests the Southern California Edison Company
(Edison) to provide the appendant facilities described on the last page hereof
and by this reference herein incorporated, hereinafter called "Interconnection
Facilities." Interconnection Facilities as defined and used herein are a group
of Added Facilities which have been designated as Interconnection Facilities, to
accommodate negotiation and preparation of contracts for parallel generation
projects. Interconnection Facilities, as are Added Facilities, shall be provided
in accordance with the applicable Tariff Schedules of Edison. Such
Interconnection Facilities are to be owned, operated and maintained by Edison.

        In consideration of Edison's acceptance of this application, Seller
hereby agrees to the following:

1.      Edison shall have the right to observe the construction of the
        Interconnection Facilities and inspect and test said facilities after
        construction is completed at the Seller's expense.

2.      Seller shall pay a monthly charge for the Interconnection Facilities'
        operation and maintenance in the amount of .9% of the added equipment
        investment as determined by Edison and as entered by Edison on the last
        page hereof. The monthly charge shall be adjusted periodically in
        accordance with the pro-rata operation and maintenance charges for added
        facilities pursuant to Rule No. 2.II 2b. The monthly charge may be based
        upon estimated costs of the Interconnection Facilities and when the
        recorded book cost of the Interconnection Facilities has been determined
        by Edison, the charges shall be adjusted retroactively to the date when
        service is first rendered by means of such

                                      -47-


        Interconnection Facilities. Additional charges resulting from such
        adjustment shall, unless other terms are mutually agreed upon, be
        payable within thirty (30) days from the date of presentation of a bill
        therefor. Any credits resulting from such adjustment will, unless other
        terms are mutually agreed upon, be refunded upon demand of Seller.

3.      Whenever a change is made in the Interconnection Facilities which
        results in changes in the added equipment investment, the monthly charge
        will be adjusted on the basis of the revised added equipment investment.
        The cost of such change shall be payable by Seller within sixty (60)
        days from the date of presentation of a bill therefor. The description
        of the Interconnection Facilities will be amended by Edison on the last
        page hereof to reflect any changes in equipment, installation and
        removal cost, amount of added equipment investment, and monthly charge
        resulting from any such change in the Interconnection Facilities or
        adjustment as aforesaid.

4.      The monthly charges payable hereunder shall commence upon the date when
        said Interconnection Facilities are available for use but not before
        service is first established and rendered through Edison's normal
        facilities and shall first be payable when Edison shall submit the first
        energy bill after such date and shall continue until the abandonment of
        such Interconnection Facilities by Seller, subject to the provisions of
        Paragraphs 3. and 4. hereof.

5.      Seller agrees to utilize said Interconnection Facilities in accordance
        with good operating practice and to reimburse Edison for damage to said
        Facilities occasioned or caused by the Seller or any of his agents,
        employees or licensees.

                                      -48-


        Failure so to exercise due diligence in the utilization of said
        Interconnection Facilities will give Edison the right to terminate this
        agreement.

6.      This Application and Contract for Interconnection Facilities supplements
        the appropriate application and contract(s) for electric service
        presently in effect between Seller and Edison.

                                      -49-

                                   (Continued)


SPECIAL CONDITIONS (Continued)
- ------------------

     3. Maximum Demand: Maximum demands shall be established for the on-peak,
mid-peak, and off-peak periods. The maximum demand for each period shall be the
measured maximum average kilowatt input indicated or recorded by instruments to
be supplied by the Company, during any 15-minute metered interval, but (except
for new customers or existing customers electing Contract Demand as defined in
these Special Conditions) not less than the diversified resistance welder load
computed in accordance with the section designated Welder Service in Rule No. 2.
Where the demand is intermittent or subject to violent fluctuations, a 5-minute
interval may be used.

     4. Billing Demand: Separate billing demands for the on-peak, mid-peak, and
off-peak time periods shall be established for each monthly billing period. The
billing demand for each time period shall be the maximum demand for that time
period occurring during the respective monthly billing period. The billing
demand shall be determined to the nearest kW.

     5. Contract Demand: A contract demand will be established by the Company,
based on applicant's demand requirements for any customer newly requesting
service on this schedule and for any customer of record on this schedule who
requests an increase or decrease in transformer capacity in accordance with Rule
No. 12 D. A contract demand arrangement is available upon request for all
customers of record on this schedule. The contract demand will be used only for
purposes of establishing the minimum demand charge for facilities required to
provide service under the rate and will not be otherwise used for billing
purposes. Contract demand is based upon the nominal kilovolt-ampere rating of
the Company's serving transformer(s) or the standard transformer size determined
by the Company as required to serve the customer's stated measurable kilowatt
demand, whichever is less and is expressed in kilowatts.

     6. Minimum Demand Charge: Where a contract demand is established, the
monthly minimum demand charge shall be $1.00 per kilowatt of contract demand.

     7. Excess Transformer Capacity: The transformer capacity in excess of a
customer's contract demand which is either required by the Company because of
the nature of the customer's load or requested by the customer. Excess
transformer capacity shall be billed at $1.00 per kVA per month.

     8. Voltage Discount: The charges before adjustments will be reduced by 3%
for service delivered and metered at voltages of from 2 kV to 10 kV; by 4% for
service delivered and metered at voltages of from 11 kV to 50 kV; and by 5% for
service delivered and metered at voltages over 50 kV; except that when only one
transformation from a transmission voltage level is involved, a customer
normally entitled to a 3% discount will be entitled to a 4% discount.

     9.  Power Factor Adjustment:
         -----------------------

         a.  Service Delivered and Metered at 4 kV or Greater:
             The charges will be adjusted each month for reactive demand. The
             charges will be increased by 20 cents per kilovar of maximum
             reactive demand imposed on the Company in excess of 20% of the
             maximum number of kilowatts.

             The maximum reactive demand shall be the highest measured maximum
             average kilovar demand indicated or recorded by metering to be
             supplied by the Company during any 15-minute metered interval in
             the month. The kilovars shall be determined to the nearest unit.
             A device will be installed on each kilovar meter to prevent
             reverse operation of the meter.

         b.  Service Delivered and Metered at Less than 4 kV:
             The charges will be adjusted each month for the power factor
             as follows:

             The charges will be decreased by 20 cents per kilowatt of measured
             maximum demand and will be increased by 20 cents per kilovar of
             reactive demand. However, in no case shall the kilovars used for
             the adjustment be less than one-fifth the number of kilowatts.

             The kilovars of reactive demand shall be calculated by multiplying
             the kilowatts of measured maximum demand by the ratio of the
             kilovar-hours to the kilowatthours. Demands in kilowatts and
             kilovars shall be determined to the nearest unit. A ratchet device
             will be installed on the kilovar-hour meter to prevent its reverse
             operation on leading power factors.

     10. Temporary Discontinuance of Service: Where the use of energy is
seasonal or intermittent, no adjustments will be made for a temporary
discontinuance of service. Any customer prior to resuming service within twelve
months after such service was discontinued will be required to pay all charges
which would have been billed if service had not been discontinued.

                     ------------ --- ----- ----- ----------

                            INTERCONNECTION STANDARDS
                            --------------- ---------



A.   General. This rule sets forth requirements and conditions for
     interconnected non Company-owned generation where such generation may be
     connected for (1) parallel operation with the service of the Company or (2)
     isolated operation with standby or breakdown service provided by the
     Company. For purposes of this rule, the interconnecting entity shall be
     designated the Producer.

B.   Conditions.

     1.   An agreement executed by the Company and the Producer shall be
          required for interconnected service. Terms for the purchase of power
          by the Company if applicable, shall be included therein.

     2.   Interconnection with the Company's system may not be made until and
          unless the Company has determined that the interconnection complies
          with the design and operating requirements set forth herein.

     3.   Where interconnection protective equipment is owned, operated and
          maintained by the Producer, the Producer shall be responsible for
          damages to the Company or to others arising out of the misoperation or
          malfunction of the Producer-owned equipment.

     4.   The Producer is solely responsible for providing adequate protection
          for the Producer's facilities interconnected with the Company's
          system.

C.   Design and Operating Requirements. Each generation facility which is or can
     be connected to the Company's electric system shall be designed and
     operated so as to prevent or protect against the following adverse
     conditions on the Company's system. These conditions can cause electric
     service degradation, equipment damage, or harm to persons:

     1.   Inadvertent and unwanted re-energization of a utility dead line or
          bus.

     2.   Interconnection while out of synchronization.

     3.   Overcurrent.

     4.   Utility system load imbalance.

     5.   Ground faults.

     6.   Generated alternating current frequency outside permitted safe limits.

     7.   Voltage generated outside permitted limits.

     8.   Poor power factor.

     9.   Harmful wave forms.

     The necessary protective equipment (relays, switchgear, transformers, etc.)
     can be provided by the Producer or by the Company.

     Explanatory information, operating rules and guidelines for meeting the
     above requirements for small (below 100 kW), medium (100-1000 kW), and
     large (above 1000 kW) facilities are contained in the Company's guidelines
     for cogenerators and small power producers. Copies of said guidelines are
     available from the Company.

D.   Interconnection Facilities.

     1.   Interconnection facilities include all required means, and apparatus
          installed, to interconnect the Producer's generation with the
          Company's system. Where the Producer desires to sell power to the
          Company, interconnection facilities include also all required means,
          and apparatus installed, to enable the Company to receive power
          deliveries from the Producer. Interconnection facilities may include,
          but are not limited to:

                                   (Continued)


D.   Interconnection Facilities. (Continued)

          a.   Connection, transformation, switching, communications, control,
               protective and safety equipment; and

          b.   Any necessary reinforcements and additions to the Company's
               system by the Company.

     2.   Where interconnection facilities are to be installed for the
          Producer's use as added facilities, the Producer shall advance to the
          Company the installed cost of the added facilities. At the Producer's
          option, and where such Producer's generation is a qualifying facility
          and the Producer has established credit worthiness to the Company's
          satisfaction, the Company shall finance those added facilities it
          deems to be removable and reusable equipment. Such equipment shall
          include, but not be limited to, transformation, disconnection, and
          metering equipment. Added facilities provided under either of the
          foregoing arrangements are subject to the monthly charge as set forth
          in Section H of the Company's Rule No. 2. Description of Service, on
          file with and authorized by the Commission.

     3.   When a Producer wishes to reserve facilities paid for by the Producer,
          but idled by an energy sale conversion, the Company shall impose a
          special facilities charge reimbursing the Company for costs related to
          its operation and maintenance of the facility. When a Producer no
          longer needs facilities for which it has paid, the Producer shall, at
          a minimum, receive from the Company credit for the net salvage value
          of the facilities dedicated to Company use. If the Company is able to
          make use of these facilities to serve other customers, the Producer
          shall receive the fair market value of the facilities determined as of
          the date the Producer either decides no longer to use the facilities
          or fails to pay the required maintenance fee.

     4.   The Producer shall be responsible for the costs of exploring the
          feasibility of a project or its interconnection with the Company
          system, including reasonable advance charges imposed by the Company
          for feasibility studies.

     5.   An interconnection line study for any Producer shall take no more than
          one year to complete.

     6.   The Producer shall be responsible for costs of telemetering and safety
          checks except to the extent that, under the Company's effective
          tariffs, a comparable customer would not be similarly charged.

     7.   The Company shall, upon request, give the Producer a binding estimate
          for line extension and interconnection costs; however, such estimates
          shall be in effect for a period not to exceed one year from the date
          provided. A reasonable breakdown of cost estimates shall also be
          provided in a form sufficiently detailed and understandable by the
          Producer.

     8.   The Company shall have the right to inspect the Producer's
          interconnection facilities prior to the commencement of parallel
          operations and require modifications as necessary.

     9.   The site of interconnection facilities shall be accessible to Company
          personnel.

E.   Interconnection Reinforcement and/or Additions. The Company's effective
     tariffs governing interconnection costs and added or special facilities
     agreements shall be applied to line and system reinforcement and/or
     additions. In addition, the following shall apply:

     1.   A Producer shall pay for new or additional line capacity if necessary
          for the Company to receive the Producer's power.

     2.   The costs of any line reinforcement and/or addition undertaken at the
          option of the Company to serve additional future customers or
          Producers shall be borne by the Company.

E.   Interconnection Reinforcement and/or Additions. (Continued)

     3.   For two or more Producers seeking to use an existing line, a first
          come, first served approach shall be used. This approach shall require
          that the first Producer to request an interconnection shall, pursuant
          to written agreement, have the right to use the existing line and
          shall incur no obligation for costs associated with future line
          capacity needed to accommodate other Producers or customers. The
          Company's Standard Offer and/or power purchase agreements for
          cogeneration and small power production facilities shall specify the
          date by which the Producer must begin construction. If that date
          passes and construction has not commenced, the Producer shall be given
          30 days to correct the deficiency after receiving a reminder from the
          Company that the construction start-up date has passed. If
          construction has not commenced after the 30-day corrective period, the
          Company shall have the right to withdraw its commitment to the first
          Producer and offer the right to interconnect on the existing line to
          the next Producer in order. If two Producers establish the right of
          first-in-time simultaneously, the two Producers shall share the costs
          of any additional line capacity necessary to facilitate their
          cumulative capacity requirements. Costs shall be shared based on the
          relative proportion of capacity each Producer will add to the line.

     4.   The applicable Company tariff provisions shall be applied to a
          Producer who pays for interconnection reinforcement and/or additions
          that later accommodate a second Producer as those provisions which
          would be applied to a comparable Company customer.

     5.   The Producer shall be responsible for the costs of only those future
          system alterations which are necessary to maintain the California
