             APPLICATION AND CONTRACT FOR INTERCONNECTION FACILITIES
                         PLUS OPERATION AND MAINTENANCE

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

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

1.       Seller shall pay to Edison, prior to the start of construction of the
         Interconnection Facilities, the total estimated costs for the
         Interconnection Facilities as determined by Edison and entered on page
         A-11 hereof. In the event Seller abandons its plans for installation of
         such Interconnection Facilities, for any reason whatsoever, including
         failure to obtain any required permits, Seller shall reimburse Edison
         upon receipt of supporting documentation for any and all expenses
         incurred by Edison pursuant to this agreement with thirty (30) days
         after presentation of a bill.

                                      A-4

                              SCE STANDARD CONTRACT
                            LONG-TERM POWER PURCHASE

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

3.       The parties also understand and agree that due to equipment acquisition
         lead time and construction time requirements, Edison requires a minimum
         of six (6) months from the time of authorization to construct the
         aforementioned Interconnection Facilities and place them in operation.
         Edison shall have no obligation to Seller with regard to any target
         date established by Seller which is less than eighteen (18) months from

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

5.      Whenever a change is made in the Interconnection Facilities which
        results in changes in the added equipment investment, the monthly
        charge will be adjusted on the basis of the revised added equipment
        investment. The cost of such change shall be payable by Seller within
        sixty (60) days from the date of presentation of a bill thereof. The
        description of the Interconnection Facilities will be amended by Edison
        on page A-10 hereof to reflect any changes in equipment, installation
        and removal cost, amount of added equipment investment, and monthly
        charge resulting from any such change in the Interconnection Facilities
        or adjustment as aforesaid.

6.      The monthly charges payable hereunder shall commence upon the date when
        said Interconnection Facilities are available for use but not before
        service is first established and rendered through Edison's normal
        facilities and shall first be payable when Edison shall submit the first
        energy bill after such date and shall continue until the abandonment of
        such Interconnection Facilities by Seller, subject to the provisions of
        Paragraphs 4 and 5 hereof.

7.      Seller agrees to utilize said Interconnection Facilities in accordance
        with good operating practice and to reimburse Edison for damage to said
        Facilities occasioned or caused by the

                                 A-6

        Seller or any of his agents, employees or licensees. Failure so to
        exercise due diligence in the utilization of said Interconnection
        Facilities will give Edison the right to terminate this Agreement.

8.      Edison's performance under this Contract is subject to the availability
        of materials required to provide the Interconnection Facilities provided
        for herein and to all applicable Tariff Schedules of Edison.

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

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

B.   Conditions.

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

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

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

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

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

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

     2.   Interconnection while out of synchronization.

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

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

          and the Producer has established creditworthiness to the Company's
          satisfaction, the Company shall finance those added facilities it
          deems to be removable and reusable equipment. Such equipment shall
          include, but not be limited to, transformation, disconnection, and
          metering equipment. Added facilities provided under either of the
          foregoing arrangements are subject to the monthly charge as set forth
          in Section H of the Company's Rule No. 2. Description of Service, on
          file with and authorized by the Commission.

     3.   When a Producer wishes to reserve facilities paid for by the
          Producer, but idled by an energy sale conversion, the Company shall
          Impose a special facilities charge reimbursing the Company for costs
          related to its operation and maintenance of the facility. When a
          Producer no longer needs facilities for which it has paid, the
          Producer shall, at a minimum, receive from the Company credit for the
          net salvage value of the facilities dedicated to Company use. If the
          Company is able to make use of these facilities to serve other
          customers, the Producer sha11 receive the fair market value of the
          facilities determined as of the date the Producer either decides no
          longer to use the facilities or fails to pay the required maintenance
          fee.

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

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

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

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

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

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

E.   Allocation of the Company's Existing Line Capacity.

     1.   a.   For purposes of interconnecting the Producer with the Company,
               existing capacity on the Company's transmission and/or
               distribution system and a priority to such line capacity will be
               allocated in accordance with the applicable Qualifying Facility
               Milestone Procedure ("QFMP"). In order to establish and maintain
               a priority for existing line capacity, the Producer must perform
               each of the milestones of such applicable QFMP.

          b.   The following Producers shall be exempt from QFMP compliance:

               1.   projects of less than 100 kW design capacity;

               2.   projects using all power internally;

               3.   Producers that executed an interconnection facilities
                    agreement prior to January 16, 1985;

               4.   Producers that bid for and receive Final Standard Offer No.
                    4 contracts; and

               5.   Producers that sign Uniform Standard Offer 1 contracts.

          c.   For a Producer that bids for and receives a Final Standard Offer
               No. 4 power purchase agreement, entitlement to existing capacity
               on the Company's transmission and/or distribution system and a
               priority to such line capacity will be established as of the date
               its bid is determined to be a winner. Such Producers must
               thereafter comply with the Commission's authorized bidding
               protocol and not default in performance of its agreement or it
               shall lose entitlement to line capacity.

E.   Allocation of the Company's Existing Line Capacity. (Continued)

     1.   (Continued)

          d.   For a Producer that signs a Uniform Standard Offer No. 1 power
               purchase agreement, entitlement to existing capacity on the
               Company's transmission and/or distribution system and a priority
               to such line capacity will be established as of the date the
               Producer pays the project fee and provides information for and
               pays the cost of the Preliminary Interconnection Study or the
               Interconnection Study pursuant to its agreement. Such a Producer
               must thereafter not default in performance of its agreement or it
               shall lose its entitlement to line capacity.

     2.   Where existing line capacity is allocated to a Producer, the Producer
          shall incur no obligation for costs associated with future line
          upgrades needed to accommodate other producers or customers. If two or
          more producers establish priority rights simultaneously, the producers
          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 producer will
          add to the line.

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

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

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

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

     4.   The Producer shall be responsible for the costs of only those future
          system alterations which are necessary to maintain the California
          Public Utilities Commission's adopted interconnection standards for
          the Producer's particular interconnection facilities. The relevant
          interconnection standards shall be those in effect at the time the
          contract is signed. Should such alterations not be directly required
          by, or beneficial to the Producer, the Producer shall be treated like
          any other customer on the Company's system.

G.   Metering.

     1.   If the Produce desires to sell electric power to the Company, the
          Company shall provide, own and maintain at the Produce's expense all
          necessary meters and associated equipment to be utilized for the
          measurement of energy and capacity for determining the Company's
          payment to the Produce pursuant to an applicable agreement.

     2.   For purposes of monitoring generator operation and determination of
          standby charges, the Company shall have the right to install
          generation metering at the Producer's expense. Where the Producer's
          generation is 10 KV or greater, telemetering equipment may also be
          required at the Producer's expense.

     3.   The Producer shall provide, at no expense to the Company, a suitable
          location for all meters and associated equipment in accordance with
          Rule No. 16.

     4.   Where necessary the Company and the Producer shall agree on an
          appropriate compensation method for transformer losses as specified in
          the agreement.

     5.   The Company shall install a ratchet device so as to prevent reverse
          operation on the meter(s) recording power provided by the Company, and
          where appropriate in each of the following cases, on (i) the meter(s)
          recording reactive demand imposed on the Company's electric system,
          and (ii) the meter(s) recording power purchased by the Company.

     6.   Provision for meter tests and adjustments of bills or payments to the
          Producer for meter error shall be consistent with Rule No. 17.

             APPLICATION AND CONTRACT FOR INTERCONNECTION FACILITIES
                          PLUS OPERATION AND MAINTENANCE
                     ("INTERCONNECTION FACILITIES CONTRACT")

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

     in changes in the added equipment investment, the monthly charge will be
     adjusted on the basis of the revised added equipment investment. The cost
     of such change shall be payable by Seller within sixty (60) days from the
     date of presentation of a bill thereof. The description of the
     Interconnection facilities will be amended by Edison on the last page
     hereof to reflect any changes in equipment, installation and removal cost,

             APPLICATION AND CONTRACT FOR INTERCONNECTION FACILITIES

                         PLUS OPERATION AND MAINTENANCE

                     ("INTERCONNECTION FACILITIES CONTRACT")

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

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

     1. It Seller elects Option I in Section A.3.7, Seller shall pay to Edison,
prior to the start of construction of the Interconnection Facilities, the total
estimated costs for the Interconnection Facility as determined by Edison and
entered on the last page hereof. In the event Seller abandons its plans for
installation of such Interconnection Facility, for any reason whatsoever,
including failure to obtain any required permits, Seller shall reimburse Edison
upon receipt of supporting documentation for any and all expenses incurred by
Edison pursuant to this Interconnection Facilities Contract within thirty (30)
days after presentation of a bill.

                                       -1-

                        LONG-TERM POWER PURCHASE CONTRACT

     2. If Seller elects Option II in Section A.3.7, Edison shall have the right
to observe the construction of the Interconnection Facilities and inspect and
test said facilities after construction is completed at the Seller's expense.

     3. The parties also understand and agree that due to equipment acquisition
lead time and construction time requirements, Edison requires a minimum of six
(6) months from the time of authorization to construct the aforementioned
Interconnection Facility and place it in operation. Edison shall have no
obligation to Seller with regard to any target date established by Seller which
is less than eighteen (18) months from the date this application is executed.
However, Edison shall exercise its best effort to meet Seller's projected
operational date.

     4. Seller shall pay a monthly charge for the Interconnection Facilities'
operation and maintenance in the amount of 0.9% of the added equipment
investment as determined by Edison and as entered by Edison on the last page
hereof. The monthly charge shall be adjusted periodically in accordance with the
pro-rata operation and maintenance charges for added facilities pursuant to Rule
No. 2.H. The monthly charge may be based upon estimated costs of the
Interconnection Facilities and when the recorded book cost of the
Interconnection Facilities has been determined by Edison, the charges shall be
adjusted retroactively to the date when service is first rendered by means of
such Interconnection Facilities. Additional charges resulting from such
adjustment shall, unless other terms are mutually agreed upon, be payable within
thirty (30) days from the date of presentation of a bill

                                       -2-

                        LONG-TERM POWER PURCHASE CONTRACT

therefor. Any credits resulting from such adjustment will, unless other terms
are mutually agreed upon, be refunded upon demand of Seller.

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

     6. The monthly charges payable hereunder shall commence upon the date when
said Interconnection Facilities are available for use but not before service is
first established and rendered through Edison's normal facilities and shall
first be payable when Edison shall submit the first energy bill after such date
and shall continue until the abandonment of such Interconnection Facilities by
Seller, subject to the provisions of Paragraphs 5. and 6 hereof.

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

                                      -3-

                        LONG-TERM POWER PURCHASE CONTRACT

diligence in the utilization of said Interconnection Facilities will give Edison
the right to terminate this Agreement.

     8. Edison's performance under this Interconnection Facilities Contract is
subject to the availability of materials required to provide the Interconnection
Facilities provided for herein and to all applicable Tariff Schedules of Edison.

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

     10. This Interconnection Facilities Contract shall at all times be subject
to such changes or modifications by the Public Utilities commission of the State
of California as said Commission may, from time to time, direct in the exercise
of its jurisdiction.
