3.    DEFINITIONS 

      3.1   Agreement:  This Standard Offer for Power Purchase and
            Interconnection with a Firm Capacity Qualifying Facility between
            SDG&E and Seller, and exhibits, as amended from time to time.

      3.2.  Alternative Energy Cost

            The lowest estimated expense per Mw-hr which SDG&E would otherwise
            have incurred in generating or purchasing 100 Mw of energy from
            alternative sources.  The value is currently determined by SDG&E's
            Energy Control Center and recorded hourly on the California Power
            Pool Economy Energy Transactions Log as the system decremental
            value.

      3.3   As-Available Capacity: That capacity level, up to the Nameplate
            Rating of the Generating Facility, Seller makes available to SDG&E
            from Initial Operation to the time Generating Facility achieves
            Reliable Operation per the terms of this Agreement.

      3.4   As-Available Capacity Payment Schedule:  SDG&E's schedule of
            time-differentiated payments and conditions for the purchase of
            As-Available Capacity from Qualifying Facilities as updated from
            time-to-time.

      3.5   Bill:  A written statement setting forth charges and requiring
            payment for electrical service, gas service, or both, as more
            fully discussed in SDG&E's Rules of Service.

      3.6   Block Curtailment:  A curtailment period scheduled by SDG&E
            consisting of one 400 consecutive hour period or two 200
            consecutive hour periods.

      3.7   Capacity Factor:  The net kilowatt-hours produced by the
            Generating Facility after Station Load and delivered to the
            Designated Point of Interconnection, for a period of time, divided
            by the product of the Firm Capacity and the number of hours in the
            period of time.

      3.8   Capacity Payment Schedule for Firm Capacity Qualifying Facilities: 
            SDG&E's schedule of prices and conditions for purchase of capacity
            from Firm Capacity Qualifying Facilities.  The capacity prices
            contained therein are derived from SDG&E's full avoided cost as
            approved by the CPUC.  SDG&E's current Firm Capacity Payment

            (b) if Seller terminates this Agreement as a result of an
            Uncontrollable Force prior to Reliable Operation of the Generating
            Facility; (c) if Seller determines as a result of either the Line
            Loss and Transmission Impact Study or the Detailed
            Interconnection/Operation Study that the project is no longer
            feasible or that transmission capacity is not available, (Seller
            must apply for a refund within ninety (90) calendar days after
            receiving written notification of the results of such study.); (d)
            if Seller determines that the cost or conditions of obtaininq
            transmission rights from the Generating Facility to SDG&E's system
            renders the project non-economic, and so notifies SDG&E no later
            than 30 days after the date such transmission rights must be
            secured under Section 5.5; (e) if the conditions of Section 28 are
            not fulfilled and this Agreement is terminated; or (f) if Seller
            terminates this Agreement as a result of the CPUC approval
            described in Section 28 not having been obtained by November 30,
            1990, and Seller notifies SDG&E in writing no later than 30 days
            after the actual date of said CPUC decision.

            4.2.2  The Project Fee, including any interest earned, shall be
            paid to SDG&E in the event Seller fails to complete each and every
            project development milestone set forth in Section 5, whether or
            not SDG&E pursues any other remedy at law or under this Agreement.

            5.9, SDG&E may terminate this Agreement and Seller shall be liable
            for liquidated damages, if any, pursuant to Section 17 of this
            Agreement and such other damages as SDG&E may be entitled to.  If
            SDG&E terminates this Agreement the provision of Sections 5.1.3
            and 5.1.4 shall also apply.

            5.1.3  If SDG&E terminates this Agreement pursuant to 5.1.2,
            Seller may execute another contract with SDG&E only under one of
            the other alternative methods described in Section 5.1.4 and only
            if the following conditions are satisfied.

            (a)  Seller provides SDG&E with a new project definition and
                 provides SDG&E a new project fee in the amount of S5/kw; and

                 have incurred as a result of Seller's failure to perform
                 under this Agreement.  Nothing in this Section 5.1.3 shall
                 limit SDG&E's remedies at law under this Agreement.

            5.1.4  If Seller satisfies the requirements of Section 5.1.3,
            Seller may execute a new contract with SDG&E, to sell power from
            the Generating Facility, by any of the following alternative
            methods:

            (a)  By fulfilling all the prerequisites for eligibility to
            execute and by executing a firm capacity standard offer contract,
            if one is available.  If Seller elects to sign a then current firm
            capacity standard offer contract within two years of the date of
            termination of this Agreement by SDG&E, the price for the firm
            capacity provided under such contract shall be the lesser of the
            then current firm capacity prices specified in the contract or the
            Firm Capacity price Seller would have received under this
            Agreement.

            (b)  By fulfilling all the prerequisites for eligibility to
            execute and by executing an available long-run standard offer
            contract if one is available.  However, Seller may not participate
            in the next long run standard offer update cycle if such cycle
            occurs within two years after the date of termination of this
            Agreement by SDG&E.

            (c)  By fulfilling all the prerequisites for eligibility to
            execute and by executing an as available standard offer contract,
            if one is available.  If Seller signs an as-available standard
            offer because no other standard offer agreement is then currently
            available, Seller may switch to another standard offer agreement
            when one becomes available subject to the conditions of such
            standard offer and this Section 5.1.4.

            (d)  A non-standard agreement subject to the negotiations between
            Seller and SDG&E.

      5.2   Submit Quarterly Status Reports

            5.2.1  Beginning on the first day of the calendar quarter
            following the date of execution of this Agreement, and continuing
            on the first day of each calendar quarter thereafter until the
            Scheduled Firm Capacity Operation Date, Seller shall submit to
            SDG&E a complete and accurate Quarterly Status Report in the form
            attached as Exhibit D.  The Quarterly Status Report shall describe
            the progress of project development and shall include without
            limitation (a) the current status of and schedule for project
            development; (b) Seller's progress since the last submitted
            Quarterly Status Report; and (c) an explanation of any changes to
            the project development schedule since Seller's last submitted
            Quarterly Status Report. If, in SDG&E's judgment, the scheduled
            development of the Generating Facility places Seller in jeopardy
            of missing a project development milestone under this Section 5,
            Seller shall, upon request, provide a summary of the steps which
            Seller has taken and proposes to take to ensure timely Reliable
            Operation of the Generating Facility.

            5.2.2  If Seller fails to provide a Quarterly Status Report in a
            timely manner or if Seller fails to submit a complete and accurate
            Quarterly Status Report, SDG&E will so notify Seller and Seller
            shall promptly provide a complete and accurate Quarterly Status
            Report. If Seller fails to provide two consecutive Quarterly
            Status Reports as provided in Section 5.2.1, SDG&E shall notify
            Seller in writing that Seller has failed to complete this project
            development milestone.  Unless Seller provides SDG&E with a
            complete and accurate Quarterly Status Report within thirty (30)
            calendar days after Seller receives such notice from SDG&E, the
            provisions of Section 5.1.2 shall apply.

      5.3   Maintain Site Control

            5.3.1  Seller warrants that it will secure, and provide evidence
            to SDG&E that it possesses, Site  Control of the site described in
            Section 2.1.3 and Exhibit A before March 31, 1990 and that Seller
            shall maintain continuous Site Control for the term of this
            Agreement.  If SDG&E does not receive evidence sufficient to
            clearly demonstrate that Seller possesses Site Control consistent 
            with Section 5.3.2 prior to said date, this Agreement  shall
            terminate and the provisions of Sections 4.2.2 and  5.1.2 apply.
            Seller shall not have additional time to cure this default.

            5.3.2  Site Control shall consist of the following, or other form
            of Site Control acceptable to  SDG&E:

            (a)  The ownership of the location of Generating Facility
            specified in Section 2.1.3;

            (b)  The leasehold interest in the location specified in Section
            2.1.3 which leasehold interest shall specifically include the
            right to construct and operate the Generating Facility at such
            location;

            (c)  Seller's exclusive and irrevocable contractual right to
            construct and operate the Generating Facility at the location
            specified in Section 2.1.3; or

            (d)  Seller's exclusive and irrevocable option to obtain any of
            the rights described in Section 5.3.2 (a) through (c) above.  This
            alternative shall only constitute Site Control prior to the
            commencement of construction of the Generating Facility.

            5.3.3  Seller shall provide SDG&E with prompt notice of any change
            in the status of its Site Control.  If, at any time, SDG&E has
            reason to believe that Seller has lost Site Control, SDG&E may
            request from Seller evidence that Seller cont- inues to possess
            Site Control.  If Seller fails to provide such evidence within
            thirty (30) calendar days after Seller receives SDG&E's request,
            the provisions of Section 5.1.2 shall apply.

            5.3.4  Where the term of Seller's Site Control does not extend for
            the full term of this Agreement, Seller shall advise SDG&E of the
            date Site Control is scheduled to expire.  Seller shall provide to
            SDG&E, no later than the date Seller's Site Control is scheduled
            to expire, evidence that Seller's Site Control has been renewed 
            or extended.  If Seller fails to provide such evidence, SDG&E
            shall notify Seller in writing that Seller is not in compliance
            with this Section 5.3.4.  Unless Seller provides SDG&E with
            evidence that Site Control has been renewed or extended within
            thirty (30) calendar days after SDG&E's notification, the
            provisions of Section 5.1.2 shall apply.

            5.3.5  This Agreement is project and site specific; however, with
            SDG&E's prior consent, Seller may be permitted to adjust the
            location of the Generating Facility within the proximity of the
            site specified in Section 2.1.3 if necessary for project
            development.

            later than said date.

            5.4.2  Seller shall pay any cost associated with the Preliminary
            Interconnection/Operating Study by the date specified in Section
            5.4.1 or within thirty (30) calendar days of billing by SDG&E,
            whichever is later.

            5.4.3  Except for Generating Facilities located out of SDG&E's
            Service Area, priority for transmission capacity on the SDG&E
            system shall be established on  the date Seller has completed the
            requirements specified in Section 5.4.1 and 5.4.2.

            5.4.4  The results of the Preliminary Interconnection/Operating
            Study are for information purposes only, except that in the event
            the date determined for providing information for and paying the
            cost of the Detailed Interconnection/Operating Study pursuant to
            Section 5.5 is  earlier than the date specified in Section 2.4.3,
            then  such earlier date shall establish the milestone date for 
            this project development milestone pursuant to Section 5.7.1.

            5.4.5  SDG&E may, at its discretion, waive the requirements of
            this Section 5.4 if SDG&E deems that a Preliminary
            Interconnection/Operating Study is unnecessary.

            5.4.6  If Seller fails to either (a) provide the information
            necessary for SDG&E to conduct the Preliminary
            Interconnection/Operating Study or (b) pay the costs of such study
            by the date required, SDG&E shall notify Seller in writing that

            service from the Generating Facility to the Point of Delivery.

            5.5.2  Such firm transmission rights must be acceptable to SDG&E
            in its sole discretion, so as to allow for the proper and safe
            delivery of power from the Generating Facility to SDG&E consistent
            with the obligations of Seller to provide SDG&E with Firm Capacity
            under  this Agreement.  SDG&E's right to approve the firm trans-
            mission rights hereunder shall not entitle it to require terms or
            conditions more burdensome than those normally contained in the
            standard practices in the utility industry with respect to
            interutility firm capacity transactions.

            5.5.3  Such firm transmission rights must commence no later than
            Initial Operation and must remain in effect for the remaining term
            of this Agreement.

            5.5.4  If Seller fails to obtain transmission rights acceptable to

            among other items, identify any line losses associated with
            delivery of Energy and Firm Capacity from the Point of Delivery to
            the Designated Point of Interconnection, as well as identify any
            impacts of operation of the Generation Facility on SDG&E's
            intertie transmission system including those which would restrict
            SDG&E's ability to economically accept power along the designating
            intertie path.

            5.6.5  The results of the Line Loss/Transmission Impact Study
            pertaining to rates for transmission losses are for informational
            purposes only.  Actual rates for losses from the Point of Delivery

            the amount by which the Firm Capacity is reduced as a result of
            such conversion.

      8.5   SDG&E shall process a request by Seller to convert between the
            Options specified in Section 8.1 and institute any changes made
            necessary by such request as expeditiously as possible given
            SDG&E's other resource commitments.  The conversion shall be
            effective on the date SDG&E notifies Seller that all changes
            necessary to accommodate such conversion have been completed.

9.    PURCHASE OF CAPACITY

      9.1   Payment for Capacity shall be based on time of delivery.  The time
            periods currently in effect are shown in Exhibit B and may be
            revised from time to  time.

      9.2   Beginning on Initial Operation and continuing until the Scheduled
            Firm Capacity Operation Date or the Firm Capacity Availability
            Date of the Generating Facility, whichever occurs later subject to
            the provisions of this Agreement, Seller shall sell and deliver
            and SDG&E shall purchase and accept, as available capacity
            produced from the Generating Facility up to the Nameplate Rating
            of the Generating Facility specified in Section 2.1.1, according
            to SDG&E's As Available Capacity Payment Schedule as updated from
            time to time.

            9.2.1  For an out-of-area Generating Facility, capacity payments
            to Seller shall be adjusted to reflect additional losses from the
            Generating Facility to the Point of Delivery and from the Point of
            Delivery to the Designated Point of Interconnection. 
            Additionally, Seller shall receive no line loss adjustments or
            credits for any line losses deemed avoided by on-system Generating
            Facilities.

      9.3   Beginning on the Scheduled Firm Capacity Operation Date or the
            Firm Capacity Availability Date of the Generating Facility,
            whichever occurs later subject to the provisions of this
            Agreement, and continuing for the remaining term of this
            Agreement, Seller shall provide and SDG&E shall purchase Firm 
            Capacity from the Generating Facility to the SDG&E system at the
            Point of Delivery in an amount and for a period as specified in
            Sections 2.2.1 and 2.1.6 respectively, according to one of the 
            following options as selected in Section 2.2.2:

                 Option 1 - Dispatchable
                 Option 2 - Actually Delivered

      9.4   SDG&E shall purchase Firm Capacity based upon one of the following
            options as selected by Seller in Section 2.2.3:

                 Option 1:   The Capacity Payment Schedule for Firm Capacity
                             Qualifying Facilities in effect at the time of
                             execution of this Agreement attached as Exhibit
                             C; and

                 Option 2:   The Capacity Payment Schedule for Firm Capacity
                             Qualifying Facilities in effect as of the
                             Scheduled Firm Capacity Operation Date of the
                             Generating Facility.

      9.5   If Seller has elected to provide SDG&E Firm Capacity according to
            the Dispatchable Option (Option 1), payments for Firm Capacity
            under this Agreement shall be calculated as follows:

            The monthly payment for Firm Capacity will be one-twelfth of the
product of the Firm Capacity Price (CP) taken from the Firm Capacity Payment
schedule in effect at the time of execution, multiplied by the Firm Capacity
(FC) and the Capacity  Bonus Factor (CBF).  Hours of curtailment and energy
deliveries  during curtailments shall be specifically excluded from the
capacity calculations.

            CP =       Firm Capacity Price
            FC =       Firm Capacity (for out-of-service area Generating      
                       Facilities, minus any adjustments for line losses from
                       the Point of Delivery to the Designated Point of
                       Interconnection)
            CBF =      Capacity Bonus Factor (see 9.7)
            ($) =      (1/12) CP x FC x CBF

      9.6   If Seller has elected to provide SDG&E with the Firm Capacity
            according to the Actually Delivered Option (Option 2), payments
            for Firm Capacity under this Agreement shall be calculated as
            follows:  The monthly payment for Firm Capacity will be the 
            product of the Period Price Factor (PPF), the Monthly Delivered
            Capacity (MDC) and the Capacity Bonus Factor (CBF), plus any
            allowable payment for outages due to scheduled maintenance.

            ($) = PPF x MDC x CBF

            The PPF is determined by multiplying the Firm Capacity Price,
            taken from the Firm Capacity Payment Schedule  in effect on the
            date of execution, by the following Al- location Factor (AF):

            AF(yr/month) x Firm Capacity Price($/kw-yr)=PPF($/kw-mo)
            Summer 0.13801 x                   =                        
            Winter 0.04428 x                   =            

            AF = The factor that allocates the Firm Capacity Price between
                 summer and winter months.  These factors may be changed upon
                 one year notice from SDG&E.

            The MDC is determined as follows:

            1)   Determine the Performance Factor (P), which is defined as
                 follows:

                 P  =   A (1-L)   (P is less than or equal to 1)
                       C x (B-S) x E

                 A  =  Total kilowatt-hours delivered during all on-peak and
                       semi-peak hours during the month excluding any Energy
                       associated with generation levels greater than the
                       Firm Capacity.

                 L  =  (for an out-of-service area Seller) The losses,
                       expressed as a decimal fraction, associated with
                       delivery of capacity purchased by SDG&E from the Point
                       of Delivery to the Designated Point of Interconnection
                       as specified in the Section 2.1.2.

                 C  =  Firm Capacity.

                 B  =  Total on-peak and semi-peak hours during the month.

                 S =   Total on-peak and semi-peak hours during the month the
                       Generating Facility is out of service on scheduled
                       maintenance.

                 E =   0.8 to reflect a 20% allowance for forced outage. 

      (2)        Determine the Monthly Capacity Factor (MCF), which is
                 computed using the following expression:

                 MCF = P x (1.0 - M)
                                  D
                 M =   The number of hours during the month the Generating
                       Facility is out of service on scheduled maintenance.

                 D =   The number of hours in the month.

      (3)        Determine the MDC by multiplying the MCF by C:            
                 MDC (kilowatts) = MCF x C

                 The monthly payment for Firm Capacity is then determined by
                 multiplying the proper PPF determined above by MDC and CBF.

                 ($) = PPF x MDC x CBF
                 CBF = Capacity Bonus Factor (See Section 9.7)

            9.6.1  Furthermore, the payment for a month in which there is an
            outage for scheduled maintenance shall also include an amount
            equal to the product of the average hourly capacity payment and
            the number of hours of outage for scheduled maintenance in the
            month calculated according to the following formula:

            Payment =  ($) x S
                       B - S

            where ($) is the monthly payment from the second paragraph of
            Section 9.6, line 6 and B and S are from paragraph 9.6(1).

      9.7   Capacity Bonus Factor.  A Seller who actually delivers Firm
            Capacity during the on-peak hours of the peak months at a Capacity
            Factor of 85%, as defined by the CPUC, is entitled to an incentive
            payment.  The Capacity Bonus Factor (CBF) will be calculated as
            follows:

            CBF = ED ( 1-L)             (CBF is greater
                   C x (PP - SP) x .85  than or equal to 1)

            ED = Energy delivered during on-peak hours of the peak months.

            L  = (for an out-of-service area Seller) The losses, expressed as
                 a decimal fraction, associated with delivery of capacity
                 purchased by SDG&E, from the Point of Delivery to the
                 Designated Point of Interconnection as specified in Section
                 2.1.2.

            C  = Firm Capacity

            PP = On-peak hours in the peak months

            SP = Total on-peak hours during the peak months that the
                 Generating Facility is out of service on Scheduled
                 Maintenance.

      Conditions

      (1)   Agreement must be in effect and Generating Facility must be
            operable for all of the peak months in order that CBF be
            calculated.

      (2)   The CBF for the period October 1 to September 30 will be
            determined by the Generating Facility's performance in the
            preceding peak months.

      (3)   CBF will be equal to 1.0 until Seller's peak months data is      
            available.

      (4)   During probationary periods CBF will be limited to 1.O.

      (5)   Hours of curtailment and energy deliveries during       
            curtailments shall be specifically excluded from the      
            capacity calculations.

      9.8   Minimum Performance Requirements: To receive capacity payments,
            the Generating Facility must meet the following requirements:

            9.8.1  The amount of Firm Capacity shall be dispatchable by SDG&E
            throughout the year (Option 1) or actually delivered to SDG&E for
            all of the on-peak hours of the peak months (Option 2).  These
            months are currently defined as the months of June, July, August
            and September, and may be changed upon one year notice by SDG&E. 
            All Energy generated by the Generating Facility at levels greater
            than the amount of Firm Capacity will be specifically excluded
            from the Firm Capacity payment calculations.  Hours of curtailment
            and energy deliveries during curtailments shall be specifically
            excluded from the capacity calculations.

            9.8.2  If Seller chooses Option 1, the Firm Capacity shall be
            dispatchable by SDG&E throughout the year, subject to a maximum 20
            percent monthly allowance for Forced Outages and scheduled
            maintenance, and also subject to an allowance for up to 45 days
            for a major overhaul.  Except during the peak months on the SDG&E
            system, Seller may accumulate and apply the 20 percent allowance
            for Forced Outages for any consecutive three (3) month period. 
            Dispatchable means that the Generating Facility is operable and is
            capable of delivering capacity, and, when called upon, must
            deliver at least the amount of capacity requested by SDG&E up to
            the full amount of Firm Capacity.  Curtailment rights are as
            defined elsewhere in this Agreement.

            9.8.3  If Seller chooses Option 2, the Firm Capacity must actually
            be delivered to SDG&E for all the on-peak hours of all the peak
            months, excluding scheduled maintenance and subject to a 20
            percent monthly allowance for Forced Outages.

      9.9   Failure to meet minimum Performance requirements.  If Seller fails
            to meet the minimum performance requirements, on a monthly basis,
            then the Seller will be placed on a probationary period not to
            exceed 15 months, and will be subject to the following:

            9.9.1  Under Option 1 (Dispatchable):  During the probationary
            period, the Seller will continue to receive capacity payments for
            the amount of dispatchable capacity available during said period. 
            During the probationary period, the Seller's monthly payment for
            capacity shall be determined by substituting for the Firm
            Capacity, the capacity at which Seller would have met the minimum
            performance requirements.  In any month during the probationary
            period that Seller does not meet the minimum performance
            requirements at whatever capacity was determined for the previous
            month, Seller's monthly payment for capacity shall be determined
            by substituting the capacity at which Seller would have met the
            minimum performance requirements.  If after the expiration of this
            period, the Seller has not demonstrated an ability to provide its
            amount of Firm Capacity to SDG&E, that capacity shall be derated
            and subsequent monthly payments limited to the new amount of
            capacity.  The amount by which the Seller's capacity is reduced
            shall be subject to Section 17 of the Agreement.

            9.9.2  Under Option 2 Actually Delivered: During the probationary
            period, the Seller shall earn capacity payments for the amount of
            capacity actually delivered.  If the Seller fails to deliver the
            full contract capacity during each of the following year's peak
            months, the amount of Firm Capacity shall be derated to the
            greater of the Firm Capacity actually delivered when the minimum
            requirements are not met, or the amount of Firm Capacity which
            would be reasonably likely to be met.  The amount by which the
            Firm Capacity is reduced shall be subject to Section 17 of the
            Agreement.

            9.9.3Hours of curtailment and energy deliveries during
            curtailments shall be specifically excluded from the capacity
            calculations.

      9.10  Scheduled Maintenance:  Scheduled Maintenance for the Generating
            Facility shall be allowed according to the following conditions:

            9.10.1  Outage periods for scheduled maintenance shall not exceed
            840 hours (35 days) in any 12 month period.

            9.10.2  Seller may accumulate unused scheduled 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.

            9.10.3  Major overhauls shall not be scheduled during the peak
            months and shall be limited to once every three years.

            9.10.4  Scheduled maintenance shall not exceed 30 peak hours
            during the peak months.

            9.10.5  Seller shall notify SDG&E 24 hours prior to a scheduled
            outage of less than one day, one week prior to a scheduled outage
            of one day or more (except for major overhauls), and six months
            prior to a major overhaul during periods acceptable to both
            parties. Agreed upon dates shall not be changed without formal
            written notice to SDG&E in accordance with Section 2.6 of this
            Agreement.

            9.10.6  Capacity payments will continue during allowed outages for
            scheduled maintenance.

      9.11  Adjustment to Firm Capacity:  Firm Capacity as specified in
            Section 2.2.1 may be adjusted only under the following conditions:

            9.11.1  Seller may increase the amount of Firm Capacity with the
            approval of SDG&E and receive payment for the additional capacity
            thereafter.  A new overall capacity price will be established
            based on the original capacity price for the original Firm
            Capacity and the applicable capacity price for the remaining term
            of this agreement published by SDG&E at the time the increase is
            first delivered to SDG&E.  This new overall capacity price will be
            prorated in proportion to the original Firm Capacity and the
            increase in Firm Capacity.

            9.11.2  Either Party may request, when it reasonably appears that
            the capacity of the Generating Facility may have changed for any
            reason, that a new Firm Capacity be determined.  If a decrease
            occurs that decrease will be subject to Section 17 of the
            Agreement.

10.   SELLER'S GENERAL OBLIGATIONS

      Seller shall:

      10.1  Design, own, construct, operate and maintain the Generating
            Facility provided that SDG&E shall have the right to require
            modifications to such design as provided in Section 11.2.

      10.2  Operate and maintain the Generating Facility in accordance with
            prudent electrical practices.  If a condition is created by Seller
            which may unreasonably interfere with the reliability or safety of
            operation of the Generating Facility or the SDG&E system, the
            Seller shall correct or eliminate such condition with reasonable
            diligence.

      10.3  Notify SDG&E:  (a) by January l, May l and September l of each
            year, of the estimated scheduled maintenance and estimated daily
            Energy and Firm Capacity for the succeeding four months and (b) by
            September 1 of each year, of the estimated scheduled maintenance
            and estimated daily Energy and Firm Capacity for the following
            year.

      10.4  If an in-service area Generating Facility, place its main
            disconnect switch under the control of both SDG&E and Seller by
            (a) allowing SDG&E to add its lock to Seller's lock on the switch
            door, (b) allowing SDG&E to stencil its markings on the switch
            door and (c) allowing SDG&E 24-hour access to the switch.  Switch
            operation shall be reserved exclusively for SDG&E and Seller
            personnel, and each Party will be able to lock out the switch.
            Switch maintenance shall be performed by Seller's personnel.

      10.5  Provide SDG&E by means of a separate, written instrument, any
            rights-of-way and access required for construction, operation,
            maintenance, inspection and testing of Interconnection Facilities
            and testing, reading of Meters and operating of Seller's main
            disconnect switch.

      10.6  Maintain proper daily Generating Facility operating records,
            including, but not limited to fuel consumption, cogeneration fuel
            efficiency, kilowatts, kilovars and kilowatt-hours generated and
            maintenance performed, and make such records as are reasonably
            needed by SDG&E to implement this Agreement available to SDG&E
            during normal business hours upon request.

      10.7  Provide to SDG&E Generating Facility electrical design and
            Interconnection Facilities design drawings for its review prior to
            finalizing Generating Facility design and before beginning
            construction work based on such drawings.  SDG&E may require
            modification of such design as provided in Section 11.2.

      10.8  Provide to SDG&E reasonable advance written notice of any changes
            in the Generating Facility or Interconnection Facilities and
            provide to SDG&E design drawings of any such changes for its
            review and approval as provided in Section 11.2.

      10.9  If an in-service area Generating Facility, test its
            Interconnection Facilities at least every 12 months, by qualified
            personnel, notify SDG&E at least 72 hours in advance of such tests
            and permit SDG&E to have a representative present at such tests.

      10.10 If an in-service area Generating Facility, design and operate the
            Generating Facility to limit the adverse effects of reactive power
            flow on the utility system.  Seller shall operate the Generating
            Facility in a manner to satisfy the reactive power requirement of
            Seller's load within the limit of the Generating Facility's
            capability as set forth in SDG&E's Electric Department Rule 21.

      10.11 Notify SDG&E of Initial Operation at least forty-five (45) days
            prior to such date.  SDG&E shall inspect the Interconnection
            Facilities within thirty (30) days of receipt of such notice.  If
            SDG&E concludes in good faith that the Interconnection Facilities
            are for any reason unacceptable, SDG&E will notify Seller in
            writing within five (5) days of completion of the inspection,
            stating the reasons for its determination.  Seller shall correct
            any deficiencies noted by SDG&E and shall provide SDG&E with the
            further right to inspect in accordance with the guidelines set
            forth above.

      10.12 Notify SDG&E at least fourteen (14) calendar days prior to:  (a)
            the initial energizing of the Point of Interconnection; (b) the
            initial operation of each of Seller's generators; and (c) the
            initial testing of Seller's protective apparatus.  SDG&E shall
            have the right to have a representative present at such times.

      10.13 Reimburse SDG&E for the cost of acquiring any property rights
            which are determined by SDG&E to be required pursuant to this
            Agreement.

      10.14 Be liable to SDG&E for any loss of whatever kind which SDG&E
            incurs as a result of (a) Seller's failure to obtain or maintain
            any necessary permit or approval, including completion of required
            environmental studies, necessary for the construction, operation
            and maintenance of the Generating Facilities, and (b) Seller's
            failure to comply with necessary permits and approvals or with any
            applicable law.

      10.15 As of Initial Operation and throughout the term of this Agreement,

            Generating Facility meets the requirements of a Qualifying
            Facility established as of the date of execution of this
            Agreement.  Seller warrants that the Generating Facility will meet
            the requirements of a Qualifying Facility as defined herein from
            Initial Operation throughout the term of this Agreement.

      10.16 Comply with the requirements of and design the Generating Facility
            consistently with SDG&E Electric Department Rule 21, to the extent
            that is clear by the context of a particular provision of Rule 21
            that such provision should apply to off-system Generating
            Facilities, provided, however that the charge for operation and
            maintenance of Line Extension and Interconnection Facilities
            specified in Rule 21 is subject to revision from time-to-time as
            authorized by the CPUC.

            of design, adequacy or capacity of the Generating Facility or
            equipment, nor shall SDG&E's acceptance of such specifications or
            designs be deemed to be an endorsement of any facility or
            equipment.  Notwithstanding anything in this Agreement to the
            contrary, SDG&E shall not be liable to Seller and Seller shall
            indemnify and hold SDG&E harmless from any claim, cost, loss,
            damage or liability, including attorney's fees and interest,
            in-connection with SDG&E's exercise of its rights under this
            Section 11.2.

      11.3  Make SDG&E Facilities' records available to Seller upon request as
            are needed by Seller to implement this Agreement.

      11.4  Make available to Seller any data filed in accordance with CPUC

            for ownership, construction, operation and maintenance of the
            Interconnection Facilities pursuant to SDG&E's Electric Department
            Rule 21.  For an out-of service area Generating Facility, SDG&E
            and Seller shall execute a Three Party Operating Agreement, in
            lieu of an Interconnection Facilities Agreement, covering design,
            purchase, installation, ownership operation and maintenance of
            Interconnection Facilities.

      12.2  If an in-service area Generating Facility, SDG&E shall own and
            shall be solely responsible for the design, purchase,
            installation, operation and maintenance of those Interconnection
            Facilities necessary to protect SDG&E's system, employees and
            customers from damage or injury arising out of or connected with
            the operation of the Generating Facility.

      12.3  If an in-service area Generating Facility, SDG&E shall design,
            own, operate and maintain the SDG&E Facilities and Line Extension
            Facilities required to connect the Generating Facility to SDG&E's
            electric system as set forth in the Interconnection Facilities
            Agreement and the Three Party Operating Agreement.

      12.4  If an in-service area Generating Facility, Seller shall be
            allocated existing line capacity in accordance with SDG&E's
            Electric Department Rule 21.

      12.5  The Parties recognize that from time to time certain improvements,
            additions or other changes in the Interconnection Facilities may
            be required for the proper and safe operation of the Generating
            Facility in parallel with SDG&E's system.  SDG&E shall have the
            right to make such changes or require Seller to make such changes,
            whichever is appropriate, upon reasonable advance written notice
            to Seller.  Seller shall reimburse SDG&E for all costs incurred by
            SDG&E for any additions or changes in the SDG&E Facilities to the
            extent required by SDG&E's Electric Department Rule 21 and the
            cost of SDG&E Facilities upon which the O&M charge is based shall
            be adjusted to reflect the cost of such changes.

      12.6  If an in-service area Generating Facility, Seller shall pay for
            operation and maintenance of Line Extension and SDG&E Facilities
            in accordance with SDG&E's Electric Department Rule 21 and Section
            14.2 of this Agreement.  Seller shall be solely responsible for
            maintaining in good operating condition all Interconnection
            Facilities owned by Seller.  When the Generating Facility is
            generating electrical energy whether or not it is operating in
            parallel with SDG&E's system, all Interconnection Facilities shall
            be in good repair and proper operating condition.

      12.7  For an out-of-service area Seller, Seller shall be responsible for
            securing all rights for transmission to the Point of Delivery. 
            Seller shall also be responsible for securing all interconnection
            arrangements with its host utility necessary for the delivery of
            power to the Point of Delivery consistent with Seller's
            obligations under this Agreement.

13.   CANCELLATION CHARGES

      Seller shall be responsible for the reimbursement to SDG&E of any and
      all cancellation charges incurred as a result of SDG&E cancelling
      order(s) for equipment necessary for the interconnection between SDG&E
      and Seller, provided that said charges be due to Seller's cancellation
      or modification of the Generating Facility.  Seller shall pay SDG&E
      within thirty (30) days after receipt of notice for said charges.

14.   BILLING AND PAYMENT

      14.1  SDG&E shall read all Meter(s) monthly according to its regular
            meter reading schedule beginning no more than thirty (30) days
            after Initial Operation.  SDG&E shall mail to Seller not later
            than thirty (30) days after the end of each monthly billing period
            (a) a Statement showing Energy and capacity delivered to SDG&E
            during each of the then currently effective Time-of-Use periods
            during the monthly billing period, (b) SDG&E's computation of the
            amount due Seller, and (c) SDG&E's check in payment of said
            amount.  If within thirty (30) days of receipt of the Statement
            Seller does not make a report in writing to SDG&E of an error,
            Seller shall be deemed to have waived any error in SDG&E's
            Statement, computation, and payment, and they shall be considered
            correct and complete.  SDG&E reserves the right to provide such
            Statement concurrently with any Bill to Seller for electric or gas
            service provided by SDG&E to Seller in accordance with applicable
            Rules of Service.  For off-system QFs, the determination of the
            amount of Energy and Capacity delivered shall be as specified in
            the Three Party Operating Agreement.

      14.2  Seller shall pay SDG&E (a) the installed cost of SDG&E Facilities
            (to the extent appropriate) and the installed cost of any Line
            Extension Facilities, (b) a monthly payment for specified SDG&E
            Facilities, if appropriate, (c) a monthly O&M Charge for Line
            Extension Facilities and SDG&E Facilities, and (d) a monthly
            charge to reimburse SDG&E for leased communication facilities when
            required by SDG&E for telemetering the Generating Facility output
            all in accordance with SDG&E's Electric Department Rule 21 and
            Interconnection/Three Party Operating Agreement. Seller shall pay
            SDG&E for such charges within fifteen (15) days of the receipt of
            a bill for any such charge.

      14.3  If either Party disputes a Statement, payment shall be made as if
            no dispute existed, pending resolution of the dispute.  If the
            Statement is determined to be in error, the amount determined to
            be in error shall be refunded by the Party owing, with monthly
            interest at a rate equal to that applied to SDG&E's Energy Cost
            Adjustment Clause pursuant to Section 9.(j).(4) of SDG&E's
            Electric Department Preliminary Statement, or successor CPUC
            approved interest rate.

      14.4  If either Party disputes a Bill, such dispute shall be resolved in
            accordance with SDG&E's applicable Rules of Service.

15.   METERING OF ENERGY DELIVERIES

      15.1  Metering for electric service to Seller and for Energy purchases
            by SDG&E shall be at the Point of Delivery or as specified in the
            Three Party Operating Agreement.  Metering will be installed which
            will measure and record flows in each direction. All the meters
            and equipment used for measuring power delivered to SDG&E shall be
            located on the side of the Interconnection Facilities selected by
            Seller and selected in Section 2.5 or as otherwise specified in
            the Three Party Operating Agreement.  If Seller selects a metering
            location on Seller's side of the Interconnection Facilities the
            power recorded as delivered to SDG&E shall be adjusted by applying
            the transformer loss compensation factor specified in Section 2.5
            to derive the amount of energy and capacity deemed delivered.  The
            transformer loss compensation factor shall be as agreed to by the
            parties or at Seller's election, shall be calculated based on the
            measured value of transformer losses from the transformer to be
            used.  If Seller chooses this latter option, Seller shall pay
            SDG&E for the cost of determining this measured value.

      15.2  All Meters shall be sealed and the seal shall be broken only by
            SDG&E, upon occasions when the Meters are to be inspected, tested
            or adjusted.

      15.3  SDG&E shall inspect and test all Meters upon their installation
            and on its regular testing schedule.  If requested to do so by
            Seller, SDG&E shall inspect or test a Meter, but the expense of
            such inspection or test shall be paid by Seller unless the Meter
            is found not to comply with the accuracy specifications found in
            SDG&E's Electric Department Rule 18, or any superseding standard.

      15.4  If a Meter is in error, Section B of SDG&E's Electric Department
            Rule 18, or any superseding standard, shall be applied.

      15.5  Seller shall report the hourly and daily Energy recordings to
            SDG&E periodically as agreed upon by the Authorized
            Representatives.  Where the Generating Facility's rated capacity
            is greater than 2 Mw, the Generating Facility's output shall be
            telemetered to SDG&E's Mission Control Center as specified in
            SDG&E's Electric Department Rule 21.

16.   CONTINUITY OF SERVICE

      16.1  SDG&E shall not be obligated to accept or pay for, and SDG&E may
            require Seller to temporarily curtail, interrupt or reduce
            deliveries of Energy upon advance notice to Seller, in order for
            SDG&E to construct, install, maintain, repair, replace, remove,
            investigate or inspect any of its equipment or any part of its
            system, or if SDG&E determines that such curtailment, interruption
            or reduction is necessary because of a System Emergency, forced
            outages on the SDG&E system or its interconnected tie lines,
            operating conditions on its system, or compliance with prudent
            electrical practices, provided that SDG&E shall not interrupt
            deliveries pursuant to this Section solely in order to take
            advantage, or to make purchases, of less expensive energy
            elsewhere.

      16.2  SDG&E shall not be obligated to accept or pay for, and may require
            Seller, with a Qualifying Facility with Nameplate Rating of one
            megawatt or greater, to temporarily curtail, interrupt or reduce
            deliveries of Energy during periods of Minimum Load Condition
            where such purchase results in "negative avoided cost" to SDG&E as
            such term is defined by the CPUC.

      16.3  Notwithstanding any other provision of this Agreement, if at any
            time SDG&E determines that either (a) the Generating Facility may
            endanger SDG&E personnel, or (b) the continued operation of the
            Generating Facility may endanger the integrity of SDG&E's electric
            system, SDG&E shall have the right upon notice to Seller, to
            disconnect the Generating Facility from SDG&E's system.  The
            Generating Facility shall remain disconnected until such time as
            SDG&E is satisfied that the condition(s) referenced in (a) or (b)
            of this Section 16.3 have been corrected.

      16.4  Whenever possible, SDG&E shall give Seller reasonable advance
            notice of its intent to refuse to purchase Energy under this
            Section 16.

      16.5  The Parties will coordinate temporary curtailment and interruption
            or reduction of deliveries of Energy required for either Party to
            construct, install, maintain, repair, replace, remove, investigate
            or inspect equipment in its respective electric system.

      16.6  Curtailment of out-of-service area Generating Facility

            16.6.1  SDG&E may curtail deliveries of Energy from the Generating
            Facility , subject to the conditions set forth in this Section. 

            16.6.2  For purposes of this Section 16.6, each day shall be
            considered to begin at midnight (0001 hrs) and end at midnight
            (2400 hrs).

            16.6.3  In the event an hour of curtailment scheduled pursuant to
            this Section 16.6. coincides with scheduled maintenance, such hour
            shall be counted as scheduled maintenance for the purposes of this
            Agreement.

            16.6.4  SDG&E shall designate the type of curtailment as either
            Flexible Curtailment or Block Curtailment.  SDG&E shall continue
            to make Firm Capacity payments for each curtailment hour subject
            to the provisions of this Section 16.6.  At the time SDG&E gives
            notice of a curtailment period, SDG&E shall also provide a
            non-binding estimate of its expected Alternative Energy Cost
            during the curtailment period.  Seller shall be provided a copy of
            SDG&E's California Power Pool Economy Energy Transactions log
            indicating SDG&E's system decremental value to verify the
            Alternative Energy Cost offers.  This information is confidential
            to SDG&E and Seller shall not provide this information to anyone
            without SDG&E's written consent.

            16.6.5 To schedule a Flexible Curtailment, SDG&E shall notify
            Seller, no later than two (2) hours prior to the start of the
            curtailment period, of the hours, duration, and Alternative Energy
            Cost for the curtailment period.  No later than one-half (1/2)
            hour after SDG&E notifies Seller of such curtailment period,
            Seller shall notify SDG&E of the level at which Seller will
            operate during the curtailment period.  If Seller fails to provide
            SDG&E such notice within the time required, SDG&E shall limit
            Seller's schedule of deliveries during the curtailment period to
            the level at which Seller was delivering to SDG&E at the time
            notice was due.  The price for Energy delivered and accepted by
            SDG&E during these periods shall be as described in Section
            16.6.8.(b).  Each Flexible Curtailment period shall have a
            duration of no less than eight (8) consecutive hours.

            16.6.6  The maximum amount of Flexible Curtailment in any calendar
            year shall be as follows:                                     
                                   Flexible          Maximum            
            Contract               Curtailment       Number of            
            Years                  Hours             Curtailments             
            1 through 9             900               125
            10 through 15           1400              125
            16 thereafter           2200              150

            16.6.7  Each year SDG&E shall notify Seller of SDG&E's intent to
            schedule a Block Curtailment within a six month time period.  When
            SDG&E better evaluates the timing of the Block Curtailment, SDG&E
            shall give Seller not less than three weeks notice of the starting
            time, duration, and Alternative Energy Cost for the Block
            Curtailment.  No later than seven (7) days after SDG&E notifies
            Seller of such curtailment period, Seller shall notify SDG&E of
            the level at which Seller will operate during the curtailment
            period.  If Seller fails to provide SDG&E such notice within the
            time required, SDG&E shall limit Seller's schedule of deliveries
            during the curtailment period to the level at which Seller was
            delivering to SDG&E at the time notice was due.  The price for
            Energy delivered and acc- epted by SDG&E during these periods
            shall be as described in Section 16.6.8.(b).  The amount of Block
            Curtailment in any Contract Year shall not exceed one 400 hour
            block or two 200 hour blocks.

            16.6.8  During each hour of Flexible or Block Curtailment,
            payments shall be made based on the following:

            a)   Firm Capacity payments shall be made in accordance with
                 Section 16.6.11.

            b)   Payments for Energy which Seller has opted to continue to
                 deliver and provided proper notice of such election in
                 accordance with Sections 16.6.5 and 16.6.7 shall be
                 purchased by SDG&E at the Alternative Energy Cost.

            c)   In the event that the output of the Generating Facility
                 during any curtailment hour exceeds the level of scheduled
                 deliveries, pursuant to Sections 16.6.5 and 16.6.7, Seller
                 shall not be paid by SDG&E for any Energy in excess of such
                 scheduled amount during such curtailment hour(s).

            16.6.9  Nothing in this Section 16.6 is intended to provide Seller
            the right, either expressed or implied, to deliver energy to SDG&E
            in amounts greater than that designated in Section 2.2.1.

            16.6.10  The maximum Energy price paid under this Section 16.6 may
            not exceed the applicable time differentiated price for a
            non-curtailment hour as provided in Sections 7 and 8.

            16.6.11  During hours of curtailment designated under this Section
            16.6, SDG&E shall continue to make Firm Capacity payments.  Under
            Option 1, hours of curtailment and energy deliveries during
            curtailments shall be specifically excluded from the capacity
            calculations. Under Option 2, for each curtailment hour, payments
            shall be made pursuant to the following: (i) payments to Seller
            for firm capacity during each on-peak or semi-peak curtailment
            hour shall be calculated using Assumed Production Factors derived
            from Seller's historical performance pursuant to Section 16.6.12,
            provided, that payments for firm capacity calculated using the
            Assumed Production Factors shall not exceed the maximum payments
            provided under Section 9, (ii) nothing in this Section 16.6 shall
            be construed to entitle Seller to payments for Firm Capacity prior
            to the Firm Capacity Availability Date, (iii) no firm capacity
            payment adjustments are applicable for curtailments during
            off-peak and super offpeak hours since no firm capacity payments
            are earned during those periods.

            16.6.12  Assumed Production Factors a) Subject to the provisions
            of Sections 16.6.4, 16.6.5 and 16.6.6, during periods of
            curtailment SDG&E shall pay Seller firm capacity payments, as
            appropriate, calculated using Assumed Production Factors derived
            from Seller's historical performance during the on-peak and
            semi-peak time periods during the previous calendar year.  The
            Assumed Production Factors shall be calculated as follows:

            APFs =     summer kwhp = summer kwhsP
                       C x (summer Hp + Summer Hsp)

            APFp =     summer kwhp
                       C x summer Hp

            where:

            APFs =     Assumed Production Factor for the summer months for
                       the combined on-peak and semi-peak periods.

            APFp =     Assumed Production Factor for the summer on-peak
                       period

            Summer Kwhp, summer kwhsp = the respective on-peak and semi-peak
            Energy (kwh) purchased by SDG&E during the previous calendar
            year's summer billing period excluding any energy purchased during
            periods of Curtailment.

            Summer Hp, summer Hsp = the respective on-peak and semi-peak hours
            during the previous calendar year's summer billing period
            excluding scheduled maintenance hours and curtailment hours under
            Section 16.

            APFw =     winter kwhp +winter kwhsp
                       C x (winter Hp + winter Hsp)

            APFw =     Assumed Production Factor for the winter months for
                       the combined on-peak and semi-peak periods winter
                       kwhp, winter kwhsp = the respective on-peak and
                       semi-peak Energy purchased by SDG&E during the
                       previous calendar year's winter billing period,
                       excluding any Energy purchased during periods of
                       curtailment.

            C =        Firm Capacity

            Winter Hp, winter Hsp = the respective on-peak and semi-peak hours
            during the previous calendar year's winter billing period
            excluding scheduled maintenance and any curtailment hours under
            Section 16.

            b)  During the first twelve (12) monthly billing cycles following
            Initial Operation, the Assumed Production Factors shall be
            calculated based on cumulative available monthly billing data. 
            After the first twelve (12) months and until a full calendar
            year's billing data is available, the Assumed Production Factors
            shall be calculated using the most recent twelve (12) monthly
            billing cycles available.

            c)  During any billing month in which a curtailment period has
            occurred during the peak or semipeak time periods under Section
            16.6, Firm Capacity payments and Bonus Payments made by SDG&E to
            Seller shall be made as follows:

            (1)  The formula for calculation of Performance Factor (P) as
                 defined in Section 9.6 shall be revised as follows:          
                   P =  Aasm(1-L)             P is less than or               
                       C x (B-S) x E           equal to 1

            where Aasm replaces A and where: Aasm = the sum of the total
            kilowatt-hours delivered during all on-peak and semi-peak hours
            excluding any kilowatt-hours delivered during hours of curtailment
            and excluding any Energy  associated with generating levels
            greater than the Firm Capacity, plus the kilowatt-hours associated
            with the applicable Assumed Production Factor for the combined
            time period(s) in which curtailment hour(s) occurred.  The
            kilowatt-hours associated with the Assumed Production Factor shall
            be calculated by multiplying the appropriate APF times the Firm
            Capacity times the hours in the on-peak and semi-peak hours in
            which curtailment was invoked during the monthly billing cycle.   
      2)    The formula for calculation of the Capacity Bonus Factor (CBF) as
            defined in Section 9.7 shall be revised as follows:

            CBF = EDasm (1-L)                CBF is greater than
            C x (PP-SP) x .85                equal to 1

            where EDasm replaces ED

            and where:

            EDasm = the sum of the Energy delivered during the on-peak hours
            of the peak months excluding any Energy delivered during hours of
            Curtailment, plus the kilowatt hours associated with the Assumed
            Production Factor calculated for the summer months.  The kilowatt
            hours associated with the Assumed Production Factor shall be
            calculated by multiplying the APFp times the Firm Capacity times
            the number of summer on-peak hours in which curtailment was
            invoked during the billing cycle.

            16.6.13  During hours of curtailment designed under this section
            16.6, Seller shall have the right to sell such curtailed energy to
            a third party.  It is Seller's obligation not to sell the
            curtailed energy on a firm basis.  If Sell has elected to sell
            energy to a third party during curtailment period, SDG&E shall
            have the right to recall such energy for delivery to SDG&E during
            such curtailment period upon giving Seller one (1) hour prior
            notice of its desire to suspend curtailment.  SDG&E will only
            suspend curtailment if circumstances change the assumptions
            underlying the scheduling of the curtailment.  Seller shall use
            its best efforts to recommence deliveries to SDG&E should SDG&E
            suspend curtailment prior to the time such curtailment period was
            scheduled to end.

17.   DEFAULT AND REMEDIES

      17.1  If either Party defaults in the due performance  or observance of
            any term or condition of this Agreement, said Party shall be in
            default.  Upon the occurrence of any default and at any time
            thereafter so long as the same shall be continu- ing, the
            non-defaulting Party may, by notice to the defaulting Party
            specifying the nature of such default, declare this Agree- ment to
            be in default.  The defaulting Party must remedy such default
            within the time specified in this Agreement, or, if no time is
            specified, within thirty (30) days after receiving written notice
            from the non-defaulting Party.  In the event that the defaulting
            Party fails to cure its default within such period of time, the
            non-defaulting Party may at any time thereafter exe- rcise, at its
            election, any rights or remedies it may have under this Agreement,
            at law or in equity to enforce the terms hereof, including, but
            not limited to, monetary damages, injunctive rel- ief, specific
            performance and termination of this Agreement.

      17.2  Nothing in this Agreement is intended to limit SDG&E's right to
            demand and Seller's obligation to provide adequate assurance in
            the circumstances described in the Uniform Commercial Code.  The
            Parties specifically intend that such rights and obligations shall
            exist whether or not the Uniform Commercial Code otherwise
            applies.

      17.3  Liquidated Damages:  Seller agrees to pay SDG&E in event of
            Seller's default, as Liquidated Damages and not as a penalty, the
            amount calculated pursuant to this Section 17.  The Parties agree
            that said calculations represent a reasonable endeavor to estimate
            fair compensation for SDG&E's foreseeable losses associated with
            Seller's failure to deliver Firm Capacity that might result from
            Seller's default or from a reduction in Firm Capacity under this
            Agreement. The amount of Seller's Liquidated Damages payment shall
            be reduced by the Project Fee, if any, paid to SDG&E pursuant to
            Section 4 of this Agreement; provided, however, if the amount of
            Seller's Liquidated Damages payment is less than the Project Fee
            paid to SDG&E pursuant to Section 4 of this Agreement, Seller
            shall not be entitled to a refund of the Project Fee or any
            portion thereof.  This Section 17 shall not preclude or limit
            SDG&E's entitlement to monetary damages for losses other than for
            failure to deliver Firm Capacity or resulting from other events of
            Seller's default.

      17.4  In the event of default, SDG&E shall bill Seller for all amounts
            due under this Agreement including the amounts calculated in
            Section 17.  Seller shall pay interest on all amounts due from the
            date of notice of default, compounded monthly, at an interest rate
            equal to the lower of (a) the maximum rate allowed by law, or (b)
            one-twelfth of the most recent month's interest rate on Commercial
            Paper (prime, three months) published in the Federal Reserve
            Statistical Release, G.13, (or if such publication is no longer
            being issued, the closest similar publication), plus 50 basis
            points (See Exhibit E). Seller shall pay SDG&E within thirty (30)
            calendar days of receipt of SDG&E's bill.

      17.5  The non-defaulting party shall have the right to offset any
            amounts due it from the defaulting party against any present or
            future payments it owes to the defaulting party and may at all
            times pursue any other remedies available to it.

      17.6  For purposes of this Section 17, "Termination Payment A" shall
            mean an amount equal to the difference between payments for Firm
            Capacity to date based on the original Agreement length and
            payments that would have been made, based upon the period of
            Seller's actual performance, up to the date of reduction or
            termination, plus interest as set forth in Section 17.4.

            17.6.1  If Seller terminates this Agreement, or all or part of the
            Firm Capacity stated in Section 2.2.1 with the following
            prescribed written notice:

            Amount of Capacity
            Terminated                        Length of Notice            
            Under 5,000 kw                      12 months
            5,000 kw to 10,000 kw               36 months
            10,000 kw to 20,000 kw              48 months
            20,001 kw and over                  60 months

            Seller shall refund to SDG&E Termination Payment A as described in
            Section 17.6.  SDG&E shall then make capacity payments to Seller
            for the remainder of Seller's perfor- mance, if any, at an
            adjusted capacity price.

            17.6.2  If Seller terminates this Agreement, or all or part of the
            Firm Capacity stated in Section 2.2.1, without the notice
            prescribed in Section 17.6.1, Seller shall pay SDG&E "Termination
            Payment B".  Termination Payment B shall consist of the sum of (a)
            Termination Payment A and (b) a one-time payment.  The one-time
            payment shall be equal to the amount of Firm Capacity being
            terminated times the difference between the Current Capacity Price
            on the date of termination for a term equal to the balance of the
            term of the Agreement and the Firm Capacity price.  This product
            shall be pro-rated for the length of notice given, if any, by
            taking the difference between the amount of months of notice
            prescribed minus the amount of months of notice given and dividing
            by twelve (See Exhibit E, Example 2).  In the event that the
            Current Capacity Price is less than the Firm Capacity price or the
            termination or reduction is a result of an uncontrollable force on
            the part of the Seller, then only Termination Payment A shall
            apply.

18.   ABANDONMENT

      18.1  If, in any six (6) month period after the Firm Capacity
            Availability Date, Seller fails to deliver to SDG&E at least the
            number of kilowatt hours derived from the product of four hundred
            and thirty-eight (438) hours times the Firm Capacity rating
            measured in kilowatts, Seller shall provide to SDG&E all of the
            following:

            18.1(a)  a written description of the reason for Seller's low
            level of performance;

            18.1(b)  a summary of the action Seller is taking to improve its
            performance; and

            18.1(c)  a schedule for bringing Seller's deliveries up to the
            Firm Capacity rating.

      18.2  In any fifteen (15) month period after the Firm Capacity
            Availability Date, Seller shall deliver to SDG&E not less than the
            number of kilowatt hours derived from the product of one thousand
            and ninety-five (1,095) hours times the Firm Capacity rating
            measured in kilowatts.  If, for any reason, Seller fails to
            deliver this minimum amount, SDG&E may terminate this Agreement on
            written notice.  Unless excused as a result of an Uncontrollable
            Force, such failure shall constitute a default, entitling SDG&E to
            its remedies at law and under Section 17 of this Agreement.

19.   NONDEDICATION OF FACILITIES

      Seller does not hereby dedicate any part of the Generating Facility to
      serve SDG&E, its customers, or the public.  SDG&E does not hereby
      dedicate any part of its system or facilities to serve or accept Energy
      and Firm Capacity from Seller to any greater extent than may be provided
      by law.

20.   LIABILITY

      20.1  Except in the case of Willful Action or sole negligence, neither
            Party shall hold the other Party, its officers, agents or
            employees liable for any loss, damage, claim, cost, or expense for
            loss or damage to property, or injury or death of persons, which
            arises out of the other Party's ownership, operation or
            maintenance of facilities on its own side of the Point of
            Delivery.

      20.2  Except as set forth in Section 20.1, each Party agrees to defend,
            indemnify and save harmless the other Party, its officers, agents,
            and employees against all losses, claims, demands, costs, or
            expenses for loss of or damage to property, or injury or death of
            persons, which directly or indirectly arise out of the
            indemnifying Party's performance pur- suant to this Agreement;
            provided, however, that a Party shall be solely responsible for
            any such losses, claims, demands, costs or expenses which result
            from its sole negligence or Willful Action.

21.   INSURANCE

      21.1  Seller, at its own expense, shall secure and maintain in effect
            during the life of this Agreement the following insu-rance as will
            protect Seller and SDG&E during the performance of operation
            hereunder:

            21.1.1  General Liability Insurance with a combined single limit
            for bodily injury and property damage of not less than (a)
            $1,000,000 each occurrence if the Generating Facility is 100 kw or
            greater; (b) $500,000 each occurrence if the Generating Facility
            is between 20 kw and 100 kw; and (c) $100,000 each occurrence if
            the Generating Facility is 20 kw or less.  Such General Liability
            Insurance shall include coverage for Premises-Operations, Owners
            and Contractors Protective, Products/Completed Operations Hazard,
            Explosion, Collapse, Underground, Contractual Liability, and Broad
            Form Property Damage including Completed Operations.

            21.1.2  The liability insurance specified in Section 21.1.1 shall
            name SDG&E as additional insured and shall contain a severability
            of interest or cross-liability clause.  The requirement to name
            SDG&E as additional insured shall be waived if such requirement
            prevents Seller from obtaining insurance as specified herein.


      21.2  Certificates of Insurance evidencing the coverages and provision
            as required in Sections 21.1.1 and 21.1.2 above shall be furnished
            to SDG&E prior to interconnected operation of the Generating
            Facility and shall provide that written notice be given to SDG&E
            at least thirty (30) days prior to cancellation or reduction of
            any coverage.  SDG&E shall have the right, but not the obligation,
            to inspect the original policies of such insurance. Seller will
            not be allowed to commence interconnected operations unless
            evidence of satisfactory insurance has been provided to SDG&E in a
            timely manner.  SDG&E will allow Seller to self-insure in lieu of
            compliance with the requirements of Section 22.1 under the
            following conditions:

            21.3.1  Seller must be a governmental agency with an established
            record of self-insurance.

            21.3.2  Seller must provide to SDG&E at least thirty (30) days
            prior to the Operation Date evidence of an acceptable plan to
            self-insure to a level of coverage equivalent to that required
            under Section 22.1

            21.3.3  If Seller ceases to self-insure to the level required
            hereunder, or if Seller is unable to provide continuing evidence
            of Seller's ability to self-insure, Seller shall immediately
            obtain the coverage required under Sections 21.1.

22.   UNCONTROLLABLE FORCE

      Neither Party shall be considered to be in default with respect to any
      obligation hereunder, other than the obligations to pay money, if
      prevented from fulfilling such obligation by reason of an uncontrollable
      force.  The term "uncontrollable force" means unforeseeable causes,
      other than Forced Outages, beyond the reasonable control of and without
      the fault or negligence of the Party claiming uncontrollable force,
      including but not limited to, acts of God, labor disputes, sudden
      actions of the elements, actions by any legislative, judicial or
      regulatory agency which conflict with the terms of this Agreement, and
      actions by federal, state, municipal, or any other government agency. 
      Whichever Party is rendered unable to fulfill any obligation by reasons
      of uncontrollable forces shall give prompt written notice of such fact
      to the other Party and shall exercise due diligence to remove such
      inability with all reasonable dispatch. Nothing in this Agreement shall
      require a Party to settle any strike or labor dispute in which it is
      involved.

23.   NON-WAIVER

      None of the provisions of this Agreement shall be considered waived by
      either Party except when such waiver is given in writing.  The failure
      of either Party to insist in any one or more instances upon strict
      performance of any of the provisions of this Agreement or to take
      advantage of any or its rights hereunder shall not be construed as a
      waiver of any such provisions or the relinquishment of any such rights
      for the future, but the same shall continue and remain in full force and
      effect.

24.   SUCCESSORS & ASSIGNS

      24.1  This Agreement shall be binding upon and inure to the benefit of
            the respective successors and assigns of the Parties.

      24.2  Neither Party shall voluntarily assign its rights nor delegate its
            duties under this Agreement, or any part of such rights or duties,
            without the written consent of the other Party, except in
            connection with the sale or merger of a substantial portion of its
            properties. Any such assignment or delegation made without such
            written consent shall be null and void.  Consent for assignment
            will not be withheld unreasonably.  Such assignment shall include,
            unless otherwise specified therein, all of Seller's rights to any
            refunds which might become due under this Agreement.

25.   EFFECT OF SECTION HEADINGS

      Section headings appearing in this Agreement are inserted for
      convenience only, and shall not be construed as interpretations of text.

26.   GOVERNING LAW

      laws of the State of California as if executed and to be performed
      wholly within the State of California.

27.   SEVERAL OBLIGATIONS

      Except where specifically stated in this Agreement to be otherwise, the
      duties, obligations and liabilities of the Parties are intended to be
      several and not joint or collective. Nothing contained in this Agreement
      shall ever be construed to create an association, trust, partnership, or
      joint venture or impose a trust or partnership duty, obligation or
      liability on or with regard to either Party. Each Party shall be
      individually and severally liable for its own obligations under this
      Agreement.

28.   CONDITIONS

      28.1  This Agreement, other than Section 28, and Sections 4.1, 4.2.1,
            4.2.2, and 5.3, is contingent on SDG&E obtaining an order from the
            CPUC that (i) SDG&E's payments made to Seller under this Agreement
            are recoverable, through SDG&E's Energy Cost Adjustment Clause,
            subject to review of the reasonableness of SDG&E's performance
            under the Agreement, and-(ii) this Agreement is reasonable and
            SDG&E's entering into this Agreement is prudent.  SDG&E will use
            best efforts and Seller shall provide such reasonable assistance
            as SDG&E may request in order to expedite obtaining such approval. 
            Both Parties shall evaluate whether the CPUC has approved this
            Agreement based upon the above criteria.  To the extent that the
            CPUC imposes conditions in its decision which increase either
            Party's risk in any respect beyond that which would be present, in
            the reasonable judgement of such Party, had the CPUC merely made
            the order specified in (i) and (ii) above, such Party may notify
            the other that the Agreement has not been Approved by the CPUC. 
            Within ten (10) days of both Parties' receipt of the CPUC
            decision, each Party shall notify the other in writing of its
            determination that the decision (a) approves this Agreement, or
            (b) does not approve this Agreement, based on the criteria above. 
            If either Party determines that the CPUC decision does not approve
            this Agreement, the Parties shall meet forthwith to modify the
            Agreement in a manner to preserve its economic integrity, and
            resubmit it to the CPUC, unless the Parties deem it unnecessary
            and provide written notice to each other consistent with this
            Section 28.1.

      28.2  Upon both Parties' providing notice to the other that this
            Agreement has been approved by the CPUC, the condition set forth
            in Section 28.1 shall be deemed fulfilled.

IN WITNESS WHEREOF, the Parties have caused Agreement to be executed in their
respective names, in duplicate by their respective official representatives as
of the day and year last written below.

                                  EXHIBIT E
                          REDUCTION AND TERMINATION

                               PAYMENT EXAMPLE

      These examples are for demonstration purposes only and should not be
construed as a projection of SDG&E Actual Termination Payments.

Example 1:

      Termination with 36 months written notice given 12 years after the
      Operation Date for termination 15 years after the Operation Date or on
      December 31, 1999.

Assumptions for this example:

      Contract Capacity - 10 megawatts (10,000 kilowatts)
      Contract Term - 25 years
      Operation Date - January 1, 1985
      Contract Capacity Price - $115 per kilowatt per year
      Monthly Interest Rate - 1% per month  (assumed to be constant)

(a)   Total Capacity Payment made = $115/kW-yr x 10,000 kw  = $1,150,000 per
      year 

(b)   Total Capacity Payments which would have been made for a 15 year
      Contract Term = $100/kW-yr x 10,000 kw = $l,000,000 per year.

(c)   The difference between (a) and (b) of annual overpayments = $1,150,000 -
      $l,000,0000/yr = $150,000/yr

Termination Payment A is then the value at the end of the 12th year of the sum
of the annual overpayments multiplied by a one (1%) percent per month interest
charge.

Termination Payment A:

$150,000/yr x 1 yr/12 months x (Compound Amount Factor at 1% per month for 12
years) = $3,988,269.

SDG&E would then pay QF $100/kW-yr for the remaining 36 months of revised
contract term. 


Example 2:

      Termination without prescribed notice 12 years after the Operation Date
      or on December 31, 1997.

Assumption for this Example:

Contract Capacity                             - 10 megawatts
                                              (10,000 kilowatts)
Contract Term                                 - 25 years
Operation Date                                - January 1, 1985
Contract Capacity Price                       - $115 per kilowatt per year
Monthly Interest Rate                         - 1% per month (Assumed to be
                                              constant)
Length of Notice Given                        - 3 months

Termination Payment B is equal in the sum of Termination Payment A (using the
same methodology as in Example 1 above), and a one-time payment, as follows:   
Termination Payment A

(a)   Total Capacity Payment made             = $115/kW-yr x 10,000 kw 
                                              = $l, 150,000/yr

(b)   Total Capacity Payment which would have been made using the same
      Capacity Payment Schedule in effect at the time of execution for a 12
      year contract term = $93/kW-yr x 10,000 kw = $930,000/yr

(c)   The difference between (a) and (b), of overpayment $1,150,000 - $930,000
      = $220,000/yr

Termination Payment A is then the value at the end of the 12th year of the sum
of the annual overpayments multiplied by one (1%) percent per month interest
charge.

Termination Payment A:

      =     $220,000/year x 1 year/12 months x (Compound Amount Factor at 1%
            month for 12 years) = $5,849,460

One Time Payment

      The payment can be formulated as follows: = (Amount of Firm Capacity
      Terminated) x (Current Capacity Price - Firm Capacity Price) x (Amount
      of Notice Prescribed - Amount of Notice Given)
            12 months/year

=     (10,000 kW)(200 S/kW-yr - 115 $/kW-yr)        (36-3 mos)
                                                    (12 mos/yr)

=     $2,337,500


Termination Payment B

      Termination Payment B  = Termination Payment A + One Time Payment
                             = $5,849,460 + $2,337,500
                             = $8,186,960

                                   RULE 21

               CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES

A.    General

      1.    This Rule presents the design and operating guidelines that should
            be applied to Cogeneration and Small Power Production sources that 
            meet the criteria for a Qualifying Facility (QF) as defined by
            Title 18, Code of Federal Regulation (CFR) Section 292.101(b)(1).
            These guidelines are necessary to facilitate safe integration of
            customer generation into the utility's system.  In addition, the
            QF must also comply with the utility's applicable rules         
            regulations.

      2.    These guidelines will cover 1) customer design requirements and
            operating procedures and 2) utility design requirements and
            operating procedures.

      3.    For the purpose of simplicity, the term customer will be used    
            in the guidelines to refer to both cogenerators and small power
            producers.

B.    Customer Systems Description

      1.    The customer may elect to use any of a variety of energy sources
            including solar, wind or other alternative energy sources, in
            addition to conventional fossil fuels.  The end conversion for
            connection to the utility's system must provide 60Hz alternating
            current.

      2.    The customer may elect to run his generator in parallel with the
            utility or as a separate system with capability of non-parallel
            load transfer between the two independent systems.  The
            requirements for these two methods of operation are outlined
            below.

C.    Separate System (See Supplement I in Section K.)

      1.    A separate system is defined as one in which there is no
            possibility of connecting the customer's generation in parallel
            with the utility's system.  For this design to be practical, the
            customer must be capable of transferring load between the two
            systems in an open transition or non-parallel mode.  This can be
            accomplished by either an electrically or mechanically interlocked
            switching arrangement which precludes operation of both switches
            in the closed position.  The customer will be required to provide
            protection to ensure adequate clearing of faults on his own
            system.

Sheet 2                      RULE 21 (Continued)

               CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES

C.    Separate System (See Supplement I in Section K.) (Continued)

      2.    If the customer has a separate system, the utility will require
            verification that the transfer scheme meets the non parallel
            requirements.  This will be accomplished by approval of drawings
            by the utility in writing and, if the utility so elects, by field
            inspection of the transfer scheme.  The utility will not be
            responsible for approving the customer's generation equipment and
            assumes no responsibility for its designor operation.

      3.    Many Uniterruptible Power Supply (UPS) systems do not specifically
            meet the separate system criteria.  However, if they are not
            capable of backfeed they will be classified as a separate system. 
            If they can backfeed, they must meet the requirements of parallel
            operation.

D.    Parallel Operation

      A parallel system is defined as one in which the customer's  generation
      can be connected to a bus common with the utility's system.  A transfer
      of power between the two systems is a direct and generally desired
      consequence.  For this operation to be practical and safe, the
      customer's equipment must meet the following conditions:

      1.    General Design Requirements

            a.   The customer's installation must meet all applicable
                 national, state, and local construction and safety codes.

            b.   All interconnection equipment at the customer's facility
                 shall be installed and maintained by the customer.  If,
                 after review of the customer's design, it is determined that
                 in addition, equipment need be installed on the utility
                 through a power purchase or interconnection agreement with
                 the customer and in accordance with this Rule.

               CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES

D.    Parallel Operation (Continued)

      1.    General Design Requirements (Continued)

            c.   A manual load break disconnect device shall be available  
                 at or near the customer's main service point(s).  This
                 disconnect device may be owned by either party but the
                 utility must have preemptory control for utility outages or
                 switching.  The disconnect device must be capable of being
                 locked in the open position if the customer has access to
                 the disconnect device (see Section K.2.a.).

            d.   Voltage regulation equipment will be required on the
                 customer's generator to maintain service voltage within
                 normal utility limits (not required under 100 Kw).

            e.   Generator characteristics shall be specified and the
                 connection to the utility's system shall be designed to
                 limit voltage harmonic distortion to less than 3% for any
                 single frequency and to less than 5% total harmonic content. 
                 If harmonic distortion causes interference to other utility
                 customers, the responsible party will redesign his system to
                 eliminate such interference.

            f.   The customer shall submit drawings and schematics of
                 interconnecting equipment and associated protection to the
                 utility for review and approval.  Typical required drawings
                 will include, but not necessarily be limited to the 
                 following prints:  single line diagram, relay functional,
                 metering on line and switch gear details, circuit breaker
                 open and close control circuits.  The utility will review
                 only those portions of the drawings and schematics which
                 apply to metering and the protection of the utility system. 
                 The utility assumes no responsibility for review or approval
                 of equipment or circuit drawings pertaining to the
                 protection of the customer's system.

D.    Parallel Operation  (Continued)

      2.    General Operating Requirements

            a.   The customer must maintain service voltage within normal
                 utility limits.  If high or low voltage complaints or
                 flicker complaints result from operation of the customer's
                 generation, such generating equipment shall be disconnected
                 until the problem is resolved.

            b.   The customer shall discontinue parallel operation when
                 requested by the utility:

                 (1)   To facilitate maintenance or repair of utility
                       facilities;

                 (2)   During system emergencies;

                 (3)   When the customer's equipment is operating in a
                       hazardous manner or is operating such that it is
                       interfering with other customers on the system.        
                       
                 NOTE: The utility may disconnect the customer from the
                       utility's system at any time without prior
                       notification, as system conditions may dictate.        
                       
            c.   The customer may not commence parallel operation of its      
                 generator(s) until final written approval has been given by
                 the utility.  The utility reserves the right to inspect the
                 customer's facility and witness testing of any equipment or
                 devices associated with the interconnection.

            d.   The utility reserves the right to inspect the customer's
                 facilities whenever it appears that the customer is
                 operating in an unsafe or harmful manner to the utility's
                 facilities, personnel or other customers.

      D.    Parallel Operation (Continued)

            2.   General Operating Requirements (Continued)

                 e.    To assure the continued and safe operation of the
                       interconnection between the utility and the customer,
                       the utility recommends that the customer maintain and
                       calibrate his equipment and protective devices
                       associated with the interconnection to the utility on
                       a repetitive basis.  The utility reserves the right to 
                       require customers to provide the utility with
                       maintenance and calibration reports.

      E.    Customer Generation Less than 100 Kw (See Supplement II in Section
            L.)

            1.   The utility shall provide and install metering, at a
                 location acceptable to the utility, as necessary to comply
                 with applicable customer generation gas and electric rate
                 schedules, power purchase contracts, or utility
                 requirements.  The installation, operation, and maintenance
                 costs of these metering facilities shall be borne by the
                 customer, except as provided in Section J.l.d.

            2.   Where service is provided at or below 480 V, the customer is
                 to be served by a dedicated distribution transformer except
                 in the following circumstances:
                 a.    The generator is under 10 kw, or
                 b.    The generator is under lOO kw and is an induction
                       generator  wherein the customer explicitly provides
                       for 24-hour immediate utility access to all
                       interconnection facilities as provided in Rule
                       l6.A.l.a.(1).

            3.   The customer should maintain his power factor within a 
                 reasonable range.  For small generators, power factor
                 correction may not be desirable.

            4.   The customer will be required to provide suitable devices to
                 ensure adequate protection for the following:

                 a.    All faults on the customer's system.
                 b.    All faults on the utility's system.
                 c.    Backfeed or start-up of a customer's generator(s) into
                       a dead utility busSheet 6

            L.)   (Continued)

            5.   The following customer protective devices are required as a
                 minimum to   effect connection and separation of the utility
                 and customer systems.  For induction generators below 10 kw,
                 the following are recommended but not required.  The
                 customer will still be responsible for providing        
                 protection for the conditions of Section E.4.              

                 a.    Individual phase overcurrent trip devices.

                 b.    Undervoltage trip devices.
      
                 c.    Underfrequency trip devices.

                 d.    Synchronizing or equivalent controls to ensure a
                       smooth connection  with the utility's system.

            6.   The requirements listed in Section E.5. are based on the
                 utility's forecast that there will be a relatively small
                 amount of customer generation versus load for any particular
                 line on the utility's system.  If a heavy saturation of
                 small power production on some line(s) does occur at a
                 future time, future customers may be required to provide     
                 additional protection at that time.  Where an induction
                 generator is to be installed, some of the trip devices may
                 be waived.  Permission to waive certain devices will be
                 given only after a check of the supply circuit (for
                 capacitance) has been made and it has been determined that   
                 the customer's generation will not be able to backfeed the
                 utility's system.

            7.   The customer shall not reconnect his generator after a
                 protective device  trip unless his system is energized from
                 the utility source or unless he has isolated his system from
                 the utility.Sheet 7

               CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES

      F.    Customer Generation Capacity 100 kw-1Mw (See Supplement III in
            Section M.)

            1.   The utility shall provide and install metering, at a
                 location acceptable to the utility, as necessary to comply
                 with applicable customer generation gas and electric rate
                 schedules, power purchase contracts, or utility
                 requirements.  The installation, operation, and maintenance
                 cost of these metering facilities shall be borne by the
                 customer.

            2.   The customer's generator(s) shall be designed and operated
                 to limit the adverse affects of reactive power flow on the
                 utility's system under all reasonably probable load
                 conditions.  Generators shall be operated in a            
                 manner to satisfy the reactive power requirement of the
                 customer's own load within the limits of the generator's
                 capability unless otherwise specified by the utility.        
                 

                 a.    For synchronous generators, sufficient generator
                       reactive capability shall be provided to withstand
                       normal voltage changes on the utility's system.        
                       
                 b.    For induction generators, capacitor installations will
                       likely be required for reactive power support.  The
                       cost of such capacitors will be borne by the customer. 
                       
            3.   The customer shall install relaying to provide adequate
                 protection for the following:

                 a.    All faults on the customer's system.

                 b.    All faults on the utility's system.

                 c.    Unbalanced or single phase conditions on the utility's
                       system.

                 d.    Backfeed or start-up of the customer's generator(s)
                       into a dead utility bus.Sheet 8

      F.    Customer Generation Capacity 100 kw-1 (See Supplement III in
            Section M.) (Continued)

            4.   Protective devices required are as follows:

                 a.    Individual phase overcurrent trip devices.             

                 b.    Undervoltage trip devices.

                 c.    Sensitive current unbalance relays.

                 d.    Synchronizing controls; either automatic or manual.

                 e.    Over/under frequency trip devices.

            5.   The customer shall not reconnect hi generator after a
                 protective device trip unless his system is energized from
                 the utility source, or unless he has isolated his system
                 from the utility.  To prevent such hazardous connections,
                 the protective devices specified in Sections F.5.b. and      
                 F.4.d. are required.  In addition generator control
                 circuit(s) must be designed to prevent accidental generator
                 connection to a dead utility system.  Design variations are
                 acceptable provided the requirements of Section F.3. are
                 satisfied.

      G.    Customer Generation Capacity Greater the 1 Mw (See Supplement IV
            in Section N.)

            1.   The utility shall provide and install metering, at a
                 location acceptable to the utility, as necessary to comply
                 with applicable customer generation gas and electric rate
                 schedules, power purchase contracts, or utility
                 requirements.  The installation, operation, and maintenance
                 costs of these metering facilities shall be borne by the
                 customer.

      G.    Customer Generation Capacity Greater the 1 Mw (See Supplement IV
            in Section N.) (Continued)

            2.   The customer's generator(s) shall be designed and operated
                 to limit the adverse affects of reactive power flow on the
                 utility's system under all reasonable probable load
                 conditions.  Generators shall be operated in a             
                 manner to satisfy the reactive power requirement of the
                 customer's own load within the limits of the generator's
                 capability unless otherwise specified by the utility.        
                 
                 a.    For synchronous generators, sufficient generator
                       reactive capability shall be provided to withstand
                       normal voltage damages on the utility's system.        
                       
                 b.    For induction generators, capacitor installations will 
                       likely be required for reactive power support.  Such
                       capacitors will be at the expense of the customer.     
                       
            3.   The customer shall install relaying to provide adequate
                 protection for the following:

                 a.    All faults on the customer's system.
      
                 b.    All faults on the utility's system.

                 c.    Unbalanced or single phase conditions, or
                       deteriorating voltage waveform conditions on the
                       customer's generator(s).

                 d.    Backfeed or start-up of the customer's generator(s)
                       into a dead utility bus.

            4.   Protective devices required are as follows:

                 a.    Individual phase overcurrent trip devices.

                 b.    Sensitive ground protection.

                 c.    Over/under voltage trip devices.

            4.   (Continued)

                 d.    Sensitive current unbalance relays.

                 e.    Synchronizing controls; either automatic or manual     
                       synchronizing supervised by a synchronizing relay.

                 f.    Over/under frequency trip devices.

                 g.    Telemetering or supervisory equipment (See Sections
                       G.6., G.7., G.8., and I.2.).

            5.   The customer shall not reconnect his generator after a
                 protective device trip unless his system is energized from
                 the utility source, or unless he has isolated his system
                 from the utility.  To prevent such hazardous connections,
                 the protective devices specified in Sections G.4/c. and      
                 G.4.e. are required.  In addition, generator control
                 circuit(s) must be designed to prevent accidental generator
                 connection to a dead utility system.  Design variations are
                 acceptable provided the requirements of Section G.3. are
                 satisfied.

            6.   Telemetering of Plant Output

                 Telemetering of the plant output (Mw, Mvar) to the Utility
                 Control Center, at customer's cost, is required when the
                 output of the customer's generation is greater than 2 Mw,
                 and the generation is operating in parallel with the
                 utility.

            7.   Utility Supervisory Control

                 When the customer is selling firm capacity greater than or
                 equal to 5 Mw to the utility, one of the following is
                 required:Sheet 11

            in Section N.) (Continued)

            7.   Utility Supervisory Control; (continued)

                 a.    Complete supervisory control system allowing operation
                       of plant generation from the Utility Control Center.

                 b.    Manning of generation facilities during all hours of
                       operation and all periods in which customer's facility
                       may be dispatched to allow operation as directed from
                       the Utility control Center.

            8.   Control and Indication of Customer's Main Breaker

                 When the total output of the customer's generation is less
                 than 5 Mw, control and indication of the customer's main
                 breaker will not generally be required.  However, this
                 decision will be made on an individual basis by the utility. 
                 
      H.    Utility System Description

            1.   The vast majority of, if not all, customers with generation
                 will be connected to the utility's distribution system. 
                 This is a radial system and past experience indicates these
                 loads are of a passive nature.  The encouragement of
                 customers to install onsite generation, however, will        
                 make backfeed a distinct possibility.  The incorporation of
                 protective devices on the customer's equipment cannot be
                 relied upon to prevent all possibilities of backfeed.  Since
                 backfeed is probable, the following design and operating
                 requirements must be incorporated.

            2.   Utility Design Requirements

                 a.    A means of disconnection must be available on both
                       sides of the utility metering; must be under the
                       control of the utility; and shall be applied to all
                       customers with parallel generation.

            2.   Utility Design Requirements (Continued)

                 a.    (Continued)

                       This can be accomplished with switches, load break
                       elbows, cutouts or secondary breakers.  Customer
                       disconnects can also be used provided that:            
                       
                       (1)   The switches meet with utility approval.         

                       (2)   The utility has pre-emptive control.

                 b.    Transformers feeding customers with parallel
                       generation shall be identified with a special tag
                       attached to the transformer or pole.  This will notify
                       field crews of the possibility of backfeed.  Incoming
                       load data sheets should be flagged and used to
                       initiate orders to tag poles.

                 c.    All maps and diagrams used by System Operators to
                       direct switching operations shall have sources of
                       parallel generation identified.

                 d.    A supervisory control and monitoring system will be
                       incorporated for those customers as specified in
                       Sections G.7. and G.8.

      I.    Utility Operation Procedures

            1.   As specified in Section H.1., backfeed from customer
                 generation is a distinct possibility.  To maintain safe
                 working conditions, strict adherence to safety rules is
                 required.  Utility procedure is to ground de-energized lines
                 and equipment upon which work will be performed.

            2.   The utility will exercise direct control over customer
                 generation to the extent allowed by the contract and
                 elsewhere in the Rule.  A supervisory system is required for
                 this control (see Sections G.7 and G.8).

      I.    Utility Operation Procedures (Continued)

            3.   The utility must have discretionary control over all
                 customer generation, independent of magnitude, during
                 outages, equipment maintenance or emergencies.

            4.   Additional safety control or procedures may be required as
                 experience dictates.

            5.   It is normal utility practice to utilize multi-shot high
                 speed reclosing on its distribution circuits.

      J.    Interconnection and Line Extension/Line upgrade Facility Cost*

            1.   General

                 a.    The installation and maintenance costs of facilities
                       related to the interconnection of a customer's
                       facility (interconnection facilities) to the utility's
                       system, utilizing the utility's normal standards,
                       shall be borne by the customer.

                 b.    The installation and maintenance costs of any line
                       extension line upgrade facilities, utilizing the
                       utility's normal standards, shall be borne by the
                       customer.  Line extension/line upgrade facilities      
                       are defined as all facilities exclusive of
                       interconnection facilities, determined by the utility
                       to be necessary to connect the utility's system to the
                       customer's point of delivery in order to accept the
                       output of the customer's generating facility.  The     
                       cost of any portion of the line extension/line upgrade
                       undertaken to serve future additional customers shall
                       be borne by the utility.

      *     As used in this Section J. only, the terms "interconnection
            facilities" and "line extension/line upgrade facilities" refer
            only to such facilities to be owned and maintained by the utility.

            1.    General (Continued)

                 c.    The customer shall be responsible for the costs of
                       exploring the feasibility of a project or its
                       interconnection with the utility's system, including
                       reasonable advance charges imposed by the utility for
                       feasibility studies.  A transmission line study for
                       any customer shall be completed by the utility within
                       the time period identified by the utility in
                       accordance with the applicable procedures as
                       established by the California Public Utilities
                       Commission.

                 d.    The customer shall be responsible for costs of
                       metering, telemetering (to the extent required under
                       this Rule), and safety checks except to the extent
                       that, under the utility's existing other rules, a
                       comparable customer would not be similarly charged. 
                       Where the customer's generating facility is less that
                       20 kw, except those customers remaining on Schedule AD
                       after June 30, 1987, and customer does not require
                       that power delivered to the utility be measured on a
                       time-of-delivery basis, the utility will bear the cost
                       of installing, operating and maintaining one standard
                       watt-hour meter (and current transformers if required)
                       to measure power flows from the customer to the
                       utility.  The customer shall provide and install
                       necessary meter sockets and enclosure equipment at or
                       near the point of delivery.

                 e.    The customer shall be responsible for the installation
                       and maintenance costs of only those future utility
                       system alterations which are necessary to maintain the
                       California Public Utilities Commission's adopted
                       interconnection standards for the customer's
                       particular interconnection facilities.  Said standards
                       shall be those in effect at the time customers and
                       utility sign the power purchase or interconnection
                       agreement.  Should a line extension/line upgrade not
                       be directly required by or beneficial to the customer,
                       the customer shall be treated like any other customer
                       on the utility's system.

      1.    General (Continued)

            f.   When the customer wishes to continue to reserve
                 interconnection and line extension/line upgrade facilities
                 which were previously paid for by the customer, but have
                 been idled by an energy sale conversion, the utility shall
                 continue to charge the customer an operation and maintenance
                 (O&M) charge for these facilities.  When the customer no
                 longer needs the facilities for which he has paid, or fails
                 to pay the required O&M charge, a termination payment due to
                 the utility or customer shall be calculated in accordance
                 with the applicable sections of the Rule and the power
                 purchase or interconnection agreement.

            g.   The utility shall treat any money collected from a customer
                 for a line extension/line upgrade that accommodates a second
                 customer in the same manner as customer advances would be
                 treated under the utility's regular line extension rules for
                 other customers.

            h.   The O&M charge required under this Section J. shall commence
                 at such time as the facilities are installed and able to be
                 used.

      2.    Allocation of the utility's Existing Line Capacity

            For purposes of interconnecting the customer with the utility,
            existing capacity on the utility's transmission and/or
            distribution system and a priority to such line capacity will be
            allocated as follows:

            a.   For a customer who receives either a final Standard Offer
                 #4, a Standard Offer #2, or a Uniform Standard Offer #1, the
                 following shall apply;

                 (1)  For a customer who bids for and receives a final
                 Standard Offer #4 Power Purchase Agreement, entitlement to
                 existing capacity on the utility's transmission and/or
                 distribution system and a priority to such line capacity
                 will be established as of the date its bid is accepted by
                 the utility; or

                 capacity on the utility's transmission and/or distribution
                 system and a priority to such line capacity will be
                 established as of the date the customer pays for and
                 provides all information necessary for the utility to
                 conduct either a preliminary or detailed interconnection
                 study; or for an out-of-service area Seller, as of the date
                 Seller pays the costs and provides all information necessary
                 for the utility to conduct a Line Loss and transmission
                 Impact Study as defined in the Standard Offer #2 Agreement;
                 or

                 (3)  for a customer who signs a Uniform Standard Offer #1
                 Agreement, entitlement to existing capacity on the utility's
                 transmission and/or distribution system and a priority to
                 such line capacity, will be establish as of the date the
                 customer both pays the Project Fee and pays the cost of, and
                 provides all information necessary for the utility to
                 conduct, either a preliminary or detailed interconnection
                 study, as defined in the Uniform Standard Offer #1
                 Agreement.

            b.   For a customer who signs a non-standard power purchase
                 agreement, entitlement to existing capacity on the utility's
                 transmission and/or distribution system and a priority for
                 such capacity will be established per the terms and
                 conditions specified in such non-standard agreement,
                 consistent with the above or as otherwise provided in such
                 non-standard contract.

            c.   If a customer fails to perform any of the obligations
                 specified in the Commission's authorized bidding protocol or
                 queue management procedures, whichever is applicable, or
                 fails to meet one of the performance milestones specified in
                 the power purchase agreement executed by the parties, the
                 customer's allocation of existing capacity and priority to
                 said line capacity shall be terminated and shall be
                 reallocated to other uses.

      Allocation of the Utility's Existing Line Capacity (Continued)

      d.    In the event that the customer losese his priority for available
            line capacity but desires to continue the project, the terms of
            the power purchase agreement and applicable law, shall determine
            whether the power purchase agreement is subject to termination as
            a result of such loss of priority, and the manner in which new
            priority may be established.

      e.    Where existing line capacity is allocated to a customer, the
            customer shall incur no obligation for costs associated with
            future line upgrades needed to accommodate other customers.  If
            existing line capacity is not sufficient to facilitate the
            customer's capacity requirements, the customer shall bear the cost
            of any additional line upgrade necessary to facilitate the
            customer's capacity requirement.  If two or more customers
            establish priority rights simultaneously, the customers shall
            share the costs of any additional line upgrade necessary to
            facilitate their cumulative capacity requirements.  Costs shall be
            shared based on the relative proportion of capacity each customer
            will add to the line.

                             after the interconnection facilities are
                             completely installed by the utility, calculate a
                             revised monthly IF charge based on the actual
                             installed cost of the removable and reusable
                             interconnection facilities.  The utility will
                             either bill or refund to the customer, as
                             applicable, to account for the difference in IF
                             charge based on the estimated versus the actual
                             installed cost of such facilities.  Once the
                             revised monthly IF charge is determined, future
                             monthly payments by the customer to the utility
                             will be at the revised monthly charge.

                       (d)   The customer will make payment to the utility of
                             a monthly operation and maintenance (O&M) charge
                             which shall be determined as 0.7% of the total
                             estimated or actual installed cost (as selected
                             in accordance with Section J.4.b.) of the
                             interconnection facilities.

                       extension/line upgrade facilities.

                 (2)   If the customer chooses to pay for installation based
                       on actual cost (as specified in Section J.4.b.), the

                       previously paid in advance to the utility by the
                       customer.

                       If the advance payment for the line extension/line
                       upgrade was shared among more than one customer, the
                       termination payment for each customer will be
                       determined in the same proportion as each customer's
                       advance payment bears to the total advance payment. 
                       If the termination payment as determined above is
