AGREEMENT NO. 2 ADDRESSING RENEWABLE ENERGY PRICING ISSUES
                                     BETWEEN
                       SECOND IMPERIAL GEOTHERMAL COMPANY
                                  QFID NO.3021
                                       AND
                       SOUTHERN CALIFORNIA EDISON COMPANY

1.    PARTIES.

The Parties to this Agreement No. 2 Addressing Renewable Energy Pricing Issues
("Agreement") are SECOND IMPERIAL GEOTHERMAL COMPANY, a California limited
partnership, ("SELLER"), and Southern California Edison Company ("EDISON"), a
California corporation. EDISON and SELLER are hereinafter sometimes referred to
individually as a "Party" and jointly as the "Parties."

2.    RECITALS.

This Agreement is entered into between the Parties with reference to the
following facts:

2.1 On April 16, 1985, SECOND IMPERIAL GEOTHERMAL COMPANY'S predecessor and
EDISON executed a power purchase agreement (the "Contract"), which establishes,
among other things, the terms and conditions pursuant to which EDISON purchases
electric power from SELLER and SELLER sells electric power to EDISON. The power
purchase agreement, together with all amendments is collectively referred to as
the "Contract."

2.2 THIS SECTION INTENTIONALLY LEFT BLANK.

2.3 Among other things, the Contract provides that EDISON will pay SELLER for
energy delivered by SELLER to EDISON in accordance with the short run avoided
cost ("SRAC") methodology established from time to time by the California Public
Utilities Commission ("Commission") for energy payments by EDISON to qualifying
facilities ("QFs").

2.4 On June 19, 2001 SECOND IMPERIAL GEOTHERMAL COMPANY'S predecessor and EDISON
entered into an Agreement Re Renewable Pricing and Payment Issues. On November
30, 2001, SECOND IMPERIAL GEOTHERMAL COMPANY'S predecessor and EDISON entered
into Amendment No. 1 to the Agreement Re Renewable Pricing and Payment Issues.
The Agreement Re Renewable Pricing and Payment Issues and Amendment No. 1 to
Agreement Re Renewable Pricing and Payment Issues are collectively referred to
as the "Renewable Fixed Price Agreement."

2.5 The Renewable Fixed Price Agreement provides, among other things, that,
notwithstanding anything in the Contract to the contrary, the SRAC for energy
delivered to EDISON by SELLER for a period of five (5) years commencing May
1, 2002 (the "Initial Fixed Rate Period"), shall be a "fixed" price of 5.37
cents/kWh (the "Initial Fixed Rate") adjusted by Time-of-Delivery ("TOD")
factors set forth in EDISON's Time-of-

                                       1

Use rate schedule "TOU-8," in lieu of payments based upon the
Commission-approved SRAC methodology.

2.6 The Parties dispute the manner in which the Commission-approved SRAC
methodology should be implemented and applied, and/or whether any new fixed
energy rate should be approved, for energy deliveries under the Contract after
the expiration of the Initial Fixed Rate Period. These issues are currently
being litigated by EDISON at the Commission in Rulemaking ("R.") 04-04-003
and R.04-04-025.

2.7 The Parties have agreed, subject to Commission Approval (as defined herein),
upon New Fixed Rates (as defined herein) to be paid to SELLER for energy
deliveries under the Contract during the New Fixed Rate Period (as defined
herein) and upon certain other terms and conditions related to their agreement
upon the New Fixed Rates and/or to be applicable during the New Fixed Rate
Period.

3.    AGREEMENT.

In consideration of the promises, mutual covenants and agreements hereinafter
set forth, the Parties hereby agree to the following:

3.1   EFFECTIVE DATE.

Except for the provisions the effectiveness of which is expressly conditioned
upon Commission Approval (as defined below), this Agreement shall become
effective on the date that it has been executed by duly authorized
representatives of each of the Parties.

3.2   ENERGY PRICING DURING NEW FIXED RATE PERIOD.

3.2.1 NEW FIXED RATES.

Subject to Commission Approval (as defined below), notwithstanding any provision
of the Contract to the contrary, commencing on May 1, 2007, and for a five (5)
year period thereafter ("New Fixed Rate Period"), SELLER hereby elects, and
EDISON agrees, that the price for energy delivered to EDISON by SELLER during
the New Fixed Rate Period, shall be the prices ("New Fixed Rates") set forth in
the table below, in lieu of the prices resulting from application of the
Commission-approved SRAC methodology; provided, however, that if the Contract
terminates in accordance with its own terms, or for any other lawful reason,
prior to the end of the New Fixed Rate Period, then the New Fixed Rate Period
shall likewise terminate; and provided further, however, that to the extent
SELLER's solar thermal facility augments its energy input with natural gas or
other clean burning alternative fuel, and with respect only to the deliveries
from such facility that would, in the absence of this Agreement, be paid
pursuant to the Commission-approved SRAC methodology, 75% of the energy price
shall be set during the New Fixed Rate Period at the applicable New Fixed Rate
and 25% of the energy price shall be calculated according to the
Commission-approved SRAC methodology applicable at the time (the "Blended Solar
Rates"). During the New Fixed Rate Period, the New Fixed Rates, or, in the case
of solar thermal projects as provided above, the Blended Solar Rates, shall be
adjusted by Time-of-Delivery ("TOD") factors set forth in EDISON's Time-of-Use
rate schedule "TOU-8." The New Fixed Rates payable during the New Fixed Rate
Period are as follows:

                                        2

                                NEW FIXED RATE (CENTS/KWH)
                                    PAYABLE FOR ENERGY

May 1, 2011 - April 30, 2012                6.3997

Commencing on May 1, 2012, the SRAC price payable to SELLER shall, for any
remaining term of the Contract, be established in accordance with the
Commission-approved SRAC methodology, TOD factors and any energy loss adjustment
factor then in effect.

3.2.2 ENERGY LOSS ADJUSTMENT FACTOR.

Unless otherwise specifically provided in the Contract, during the New Fixed
Rate Period, the energy loss adjustment factor ("ELAF") applicable to energy
deliveries made to EDISON by SELLER will be 1.0.

3.3   RELATIONSHIP TO COMMISSION SRAC PROCEEDING.

Effective upon Commission Approval (as defined below), the Parties forever
relinquish any rights or claims to pay or to be paid for energy deliveries
during the New Fixed Rate Period based upon terms or a rate of payment other
than those set forth in this Agreement. The Parties further agree not to seek to
enforce any order by the Commission or any court or governmental agency having
jurisdiction that establishes terms or a rate of payment for energy deliveries
during the New Fixed Rate Period other than those that set forth in this
Agreement.

3.4   ENVIRONMENTAL ATTRIBUTES, CAPACITY ATTRIBUTES AND RESOURCE ADEQUACY
      BENEFITS.

3.4.1 SELLER'S EXCLUSIVE CONVEYANCE TO EDISON OF ENVIRONMENTAL ATTRIBUTES,
      CAPACITY ATTRIBUTES AND RESOURCE ADEQUACY BENEFITS.

Subject to Commission Approval (as defined below), SELLER shall dedicate and
convey all Environmental Attributes, Capacity Attributes and Resource Adequacy
Benefits generated or produced by SELLER during the New Fixed Rate Period to
EDISON and EDISON shall be given sole title during the New Fixed Rate Period to
all such Capacity Attributes, Environmental Attributes and Resource Adequacy
Benefits. SELLER has not and will not convey to any person or entity other than
EDISON any Environmental

                                        3

Attributes, Capacity Attributes and Resource Adequacy Benefits associated with
the output from SELLER'S generating facility throughout the New Fixed Rate
Period.

SELLER shall use commercially reasonable efforts to take all actions and execute
all documents or instruments necessary (or to support EDISON's efforts) such
that, upon the commencement of the New Fixed Rate Period and continuing until
the end of the New Fixed Rate Period: (i) SELLER's generating facility is
certified by the California Energy Commission ("CEC") as an Eligible Renewable
Energy Resource ("ERR") for purposes of the RPS Legislation; and (ii) all
electrical output delivered to Edison from the generating facility is certified
by the CEC as an ERR for purposes of the RPS Legislation.

In addition, SELLER shall take all actions and execute all documents or
instruments necessary to effectuate the use of the Resource Adequacy Benefits
associated with SELLER's generating facility for Edison's sole benefit
throughout the Fixed Rate Period.

Such actions shall include, without limitation:

     Cooperating with and encouraging the regional entity responsible for
     resource adequacy administration to certify or qualify the generating
     facility capacity for resource adequacy purposes;

     Testing the generating facility in order to certify the generating facility
     capacity for resource adequacy purposes; and

     Committing to EDISON the generating facility capacity.

SELLER grants EDISON exclusive right, at any time or from time-to-time during
the Fixed Rate Period, to sell, assign, convey, transfer, allocate, designate,
award, report or otherwise provide any and all such Environmental Attributes,
Capacity Attributes and Resource Adequacy Benefits to third parties.

The inclusion in this Agreement of this Section 3.4 shall not be interpreted to
support any Parties' position with respect to the ownership, or lack thereof, of
Environmental Attributes, Capacity Attributes or Resource Adequacy Benefits
associated with SELLER's generating facility and the electrical output of such
generating facility under the Contract during periods other than the New Fixed
Rate Period. The Parties expressly reserve their respective positions with
respect to the ownership of Environmental Attributes, Capacity Attributes or
Resource Adequacy Benefits associated with SELLER's generating facility and the
electrical output of such generating facility under the Contract during periods
other than the New Fixed Rate Period.

3.4.2 DEFINITIONS.

For purposes of this Agreement, the following terms shall have the following
meanings:

     "Environmental Attributes" means any and all credits, benefits, emissions
     reductions, offsets, and allowances, howsoever entitled, attributable to
     the generation from SELLER's generating facility and its displacement of
     conventional electric energy generation. Environmental Attributes include
     but are not limited to (i) any avoided emissions of pollutants to the air,
     soil or water such as sulfur oxides (SOx), nitrogen oxides (NOx),
     carbon monoxide (CO) and other pollutants; (ii) any avoided emissions of
     carbon dioxide (CO2), methane (CH4) and other greenhouse gases (GHGs)
     that have been determined by the United

                                        4

Nations Intergovernmental Panel on Climate Change to contribute to the actual or
potential threat of altering the Earth's climate by trapping heat in the
atmosphere; and (iii) the reporting rights to these avoided emissions, such as
Green Tag Reporting Rights. Green Tag Reporting Rights are the right of a Green
Tag Purchaser to report the ownership of accumulated Green Tags in compliance
with federal or state law, if applicable, and to a federal or state agency or
any other party at the Green Tag Purchaser's discretion, and include, without
limitation those Green Tag Reporting Rights accruing under Section 1605(b) of
The Energy Policy Act of 1992 and any present or future federal, state, or local
law, regulation or bill, and international or foreign emissions trading program.
Green Tags are accumulated on a kWh basis and one Green Tag represents the
Environmental Attributes associated with one (1) MWh of electric energy.

Environmental Attributes do not include (i) any electric energy, capacity,
reliability or other power attributes from SELLER's generating facility, (ii)
production tax credits associated with the construction or operation of SELLER's
generating facility and other financial incentives in the form of credits,
reductions, or allowances associated with SELLER's generating facility that are
applicable to a state or federal income taxation obligation, (iii) fuel-related
subsidies or 'tipping fees' that may be paid to SELLER to accept certain fuels,
or local subsidies received by the SELLER for the destruction of particular
pre-existing pollutants or the promotion of local environmental benefits, or
(iv) emission reduction credits encumbered or used by SELLER's generating
facility for compliance with local, state, or federal operating and/or air
quality permits. If SELLER's generating facility is a biomass or landfill gas
facility and SELLER receives any tradable Environmental Attributes based on the
greenhouse gas reduction benefits or other emission offsets attributed to its
fuel usage, it shall provide EDISON with sufficient Environmental Attributes to
ensure that there are zero net emissions associated with the production of
electricity from such facility.

"ERR" means an eligible renewable energy resource for purposes of the RPS
Legislation.

"Capacity Attributes" means any and all current or future defined
characteristics certificates, tag, credits, ancillary service attributes, or
accounting constructs, howsoever entitled, including any accounting construct
counted toward any resource adequacy requirements, attributed to or associated
with SELLER's generating facility or any unit of generating capacity of the
generating facility during the New Fixed Rate Period.

"Resource Adequacy Benefits" means the rights and privileges attached to any
generating resource that satisfies any entity's resource adequacy obligations,
as those obligations are set forth in any Resource Adequacy Rulings.

"Resource Adequacy Rulings" means Commission Decisions 04-01-050, 04-10-035 and
any subsequent Commission ruling or decision, or any other resource adequacy
laws, rules or regulations enacted, adopted or promulgated by any applicable
governmental authority, as such decisions, rulings, laws, rules or regulations
may be amended or modified from time to time during the New Fixed Rate Period.

                                        5

     "RPS Legislation" means the State of California Renewable Portfolio
     Standard Program, as codified at California Public Utilities Code Section
     399.11 et seq. or any successor to this legislation.
