being or will be transferred to Operator and/or the Project Partnerships are
referred to herein as the "Asset Transfer Documents".

     E.   The Project Partnerships own the following geothermal electrical
generating projects (which include, without limitation, power generation
facilities, related geothermal steam fields, drilling pads, exploratory,
production and injection wells, pipelines, separators and other equipment (each,
a "Project")), and intend to utilize the Leases, the Jointly-Owned Assets (as
that term is defined below) and the Right of Way Grants (collectively, the
"Cotenancy Assets") in connection with the Projects.  More specifically:

          (1) CED owns the Project commonly known as the "BLM Project" (which
     consists of the "BLM East" and "BLM West" facilities), which is located on
     land in the vicinity of the Leasehold Premises, which land is leased from
     the BLM and is included in the Coso Known Geothermal Resource Area in the
     China Lake area of California (the "KGRA").

          (2) CPD owns the Project commonly known as the "Navy II Project",
     which is located on land in the vicinity of the Leasehold Premises, which

          5.2.  Plant Resource and Use Requirement.  Notwithstanding any other
provision of this Agreement, each Project Partnership shall be entitled to enter
upon and use the Leasehold Premises for geothermal resource production and
injection purposes if such Project Partnership determines, in its exercise of
reasonable business judgement, that it has insufficient steam economically
available to it from other sources.  If such a determination is made, then such
Project Partnership may utilize the geothermal resources on the Leasehold
Premises to the extent of the geothermal resources reasonably required to be
produced, or spent geothermal effluent reasonably required to be injected, in
order to maximize the operation and profitability of its Project (the "Plant
Resource and Use Requirement").

          6.1  The Leasehold Premises.  Except as otherwise provided in this
Agreement, the Project Partnerships intend that any buildings, structures,
facilities, improvements, fixtures, wells, sumps, ponds, machinery, tools,
equipment or other real or personal property constructed, installed or placed
upon the Leasehold Premises shall belong exclusively to the Project Partnership
that paid for or funded the same.  In that regard:

               6.1.1     The CED Existing Wells.  The Project Partnerships
acknowledge that the prior operator, on behalf of CED, drilled on the Leasehold
Premises those certain production wells designated as Well 58A-18 and Well 58B-
18, and installed on the Leasehold Premises certain wellhead valves, piping,
pipe supports and other equipment required to transport geothermal resources
from such wells to the BLM Project (collectively, the "CED Existing Wells"), all

additional buildings, structures, facilities, improvements, fixtures, wells
(whether production, injection or exploratory), sumps, ponds, machinery, tools,
equipment or any other real or personal property on the Leasehold Premises
(each, an "Additional Asset"), then such Additional Asset shall belong
exclusively to such Project Partnership, and no other Project Partnership shall
have any right, title or interest therein. The CED Existing Wells and all the
Additional Assets are individually and collectively referred to herein as the
"Individually-Owned Assets").

          6.2  The Right of Way Property.   The Project Partnerships intend that

Individually-Owned Assets.  The Operator shall coordinate, manage and implement
all repairs and other matters associated with any such damage or destruction.

          10.2.   Condemnation.  The Project Partnerships shall collectively
bear the risk of a taking of the Property, the Jointly-Owned Assets or any part
thereof by eminent domain, each in proportion to its Interest; except that each
Project Partnership shall bear the risk of a taking of its Individually-Owned
Assets.  The Operator shall coordinate, manage and implement all matters
associated with any such taking.

     11.  SALE OR OTHER TRANSFER OF INTERESTS; WAIVER OF PARTITION

          11.1.  In General.  In the circumstances set forth in this Section 11,
a Project Partnership may be compelled to offer to sell, and to then sell, its
Interest to one or more of the other Project Partnerships.  In all such
circumstances, the offeror-Project Partnership is referred to herein as the
"Selling Project Partnership" and the offeree-Project Partnership or Project
Partnerships are collectively referred to herein as the "Remaining Project
Partnerships".

          11.2.  Voluntary Sales. (a) no partial sales or other partial
transfers of Interests shall be permitted except to other Project Partnerships;
(b) no Project Partnership shall be permitted to sell or otherwise transfer its
Interest separately from its Individually-Owned Assets; and (c) no Project
Partnership shall have the right to sell or otherwise transfer its entire
Interest to any other person or entity that is not a Project Partnership, or
surrender its interest in the Cotenancy Assets or any part thereof to the BLM,
unless it first offers to sell such Interest to the other Project Partnerships.

                 11.2.1. The Interest which the Selling Project Partnership
intends to sell, transfer or surrender shall first be offered in writing (such
written offer being hereafter referred to as the "Offering Notice") to all the
Remaining Project Partnerships at the stated price at which the Interest is
proposed to be sold or otherwise transferred to such third person or entity and
on the proposed terms thereof. The Remaining Project Partnerships, collectively
and individually, shall have a period of thirty (30) days after the giving of
the Offering Notice (as determined in accordance with Section 15.3 hereof) in
which to accept or reject said offer (the "Offer Period").

                 11.2.2. If the Remaining Project Partnerships, or any of them,
accepts the offer within the Offer Period, then the purchase and sale shall be
completed as soon as reasonably possible, and all costs and expenses associated
with such purchase and sale shall be borne by the Selling Project Partnership.
If no Remaining Project Partnership elects, within the Offer Period, to purchase
the Selling Project Partnership's Interest, then the Selling Project Partnership
may (a) surrender its interest in the Cotenancy Assets or any thereof to the BLM
or (b) sell or otherwise transfer its Interest to any third person or entity
during the three (3) month period immediately following the expiration of the
Offer Period, but not at a price lower than the

                                       10


proposed price or on terms more favorable to the purchaser than the proposed
terms set out in the Offering Notice. After the expiration of said three (3)
month period, the Selling Project Partnership's interest may not be sold,
transferred or surrendered without that Interest again first being re-offered to
the Remaining Project Partnerships in accordance with Section 11.2.1 hereof.

          11.3.  Other Events Constituting Offers to Sell.

                 11.3.1. Upon the occurrence of any of the following events
(each, an "Offer To Sell Event"), such event shall be deemed to constitute an
offer by the affected Project Partnership, or its principals or successors-in-
interest, or the trustee of its estate, as the case may be (the appropriate one
of which shall be deemed to be the Selling Project Partnership for purposes of
this Section), to sell its entire Interest to the other Project Partnerships, or
any of them, for the price determined under Section 11.3.2 hereof:

                    a.   The dissolution of such Project Partnership;

                    b.   The voluntary or involuntary filing of a petition in
     bankruptcy or for protection under similar insolvency Laws, or any general
     assignment of assets for the benefit of creditors; or

                    c.   Any Default under (and as that term is defined in)
     Section 13.1 hereof.

                 11.3.2.   Upon an Offer To Sell Event, the Remaining Project
Partnerships, collectively or individually, shall have the right to purchase the
Selling Project Partnership's Interest for an amount equal to the sum of the
then-current fair market value of (a) such Interest and (b) any Individually-
Owned Assets owned by the Selling Project Partnership, by giving written notice
to the Selling Project Partnership within thirty (30) days after the occurrence
of the Offer To Sell Event.  If the Selling Project Partnership and the
Remaining Project Partnerships cannot agree on such fair market value, then,
within fifteen (15) days after a written demand by the Selling Project
Partnership or the Remaining Partnerships, the parties shall either (i) jointly
appoint an M.A.I. appraiser for the purpose of determining said fair market
value or (ii) failing such joint action, each separately designate an M.A.I.
appraiser.  In the latter case, within five (5) days after their appointment,
the designated appraisers shall jointly designate a third M.A.I. appraiser,
whose determination of such Interest's and Individually-Owned Assets' fair
market value shall be binding and conclusive.  The failure of the Selling
Project Partnership or the Remaining Partnerships to timely appoint an appraiser
shall be deemed an express approval of the other party's appraiser, and such
appraiser's appraisal shall determine and be the fair market value.  The fees of
the appraiser(s) shall be paid in equal shares by said parties.

          11.4.   Notwithstanding anything contained in this Agreement, the
Governing Documents or any rule of law or equity which would otherwise allow the
Project Partnerships to partition or to seek or obtain a partitioning of the
Cotenancy Assets, the Project Partnerships shall not have and hereby waive the
right to partition all or any portion of the Cotenancy Assets, or to make
application to any court or authority or to commence or prosecute any action or
proceeding for partition of the Cotenancy Assets.  Each Project Partnership and
the Lender shall

                                       11


be entitled to a decree or order restraining or enjoining such partition,
application, action or proceeding upon any breach of the provisions of this
Section 11.4.  The Project Partnerships acknowledge and agree that they have
been paid full consideration for the waiver herein provided.  The Lender is
hereby made a third-party beneficiary of the waiver and covenants herein
provided; and the Project Partnerships agree that they will not participate in
or permit any revocation, termination or amendment of such waiver or covenants
without the prior written consent of the Lender.

     12.  TRANSFER, TERMINATION AND AMENDMENT OF THE LEASES AND THE RIGHT OF WAY
GRANTS.  Except as expressly provided herein, the Cotenancy Assets or any
portion thereof may be sold or otherwise transferred, or may be amended or
terminated, only upon (a) the written agreement of all of the Project
Partnerships and (b) approval of the Lender if such approval is required under
Section 14 hereof.  Subject to Section 14 hereof, each of the Project
Partnerships hereby covenants and agrees to execute all documents as may be
required to effect any such approved sale, other transfer, amendment or
termination.  Subject to the terms and conditions of the Financing Documents (as
that term is defined in the Indenture), the proceeds from any sale of the
Cotenancy Assets or any specific portion thereof shall be divided among the
Project Partnerships in proportion to their respective Interests; provided,
however, that such division shall be equitably adjusted to take into account the
fair market value (which shall be determined in a manner consistent with Section
11.3.2 hereof) of any Individually-Owned Assets existing on the Property on the
date of such sale.  All costs and expenses directly resulting from the sale or
other transfer of the Cotenancy Assets, including, without limitation, escrow
costs, title insurance premiums and documentary transfer taxes, shall be divided
among the Project Partnerships in proportion to their respective Interests.

     13.  DEFAULT AND REMEDIES

          13.1.  Events of Default; Default. If a Project Partnership shall fail
to perform its obligations hereunder in any material respect (an "Event of
Default"), then such Project Partnership shall not be in Default hereunder
unless such Project Partnership shall have failed to cure such Event of Default
within thirty (30) days after such Project Partnership has received written
notice of such Event of Default ("Notice of Default") from a non-defaulting
Project Partnership or the Operator; provided, however, that if the nature of
such obligation or obligations is such that more than thirty (30) days are
required, in the exercise of commercially reasonable diligence, for performance
of such obligation(s), then such Project Partnership shall not be in Default if
it commences such performance within such thirty (30) day period and thereafter
pursues the same to completion with commercially reasonable diligence.  A
Project Partnership shall be in "Default" hereunder if its Event of Default is
not cured within the time set forth above in this Section.

          13.2.  Remedies.  In addition to all other remedies permitted by Law
or under this Agreement (all of which shall be cumulative), the Project
Partnership or Project Partnerships, as the case may be, that is/are not in
Default hereunder, shall have the right to purchase the Interest of the Project
Partnership that is in Default hereunder, as provided in Section 11.3 hereof.



                                       12


          13.3.  Performance By Non-Defaulting Project Partnership(s).  In the
event that any Project Partnership fails to make any payment or perform any
obligation required to be made or performed by such Project Partnership
hereunder, under the Leases or under the Right of Way Grants (regardless whether
the same constitutes a Default hereunder), then any other Project Partnership or
the Operator shall be entitled (but not obligated) to make the required payment
or perform the required obligation in fulfillment of such Project Partnership's
obligations, whereupon the defaulting Project Partnership shall, upon demand,
reimburse the paying or performing Project Partnership(s) or the Operator, as
the case may be, for the amount of such payment and the cost of such
performance.

          13.4.  Specific Performance.  The Project Partnerships agree that
damages may be an inadequate remedy for a Default under this Agreement, the
Leases or the Right of Way Grants and that each Project Partnership shall be
entitled to seek injunctive and other equitable relief against any other Project
Partnership to prevent or eliminate such Default.

     14.  LENDER PROTECTIONS

          14.1.  The following provisions are for the benefit of the Lender, and
shall be in effect while there exists any outstanding amount payable, or any
performance required, under the Indenture (as that term is defined below),
including, without limitation, any amount payable under the Senior Secured Notes
(as that term is defined in the Indenture). Once all of the outstanding amounts
payable and all performance required under the Indenture have been fully paid
and performed, all references in this Agreement to the Lender shall be deemed
null and void and all such provisions shall, without any further actions, have
no further force and effect.

          14.2.    The Lender shall have the right, but not the obligation, upon
the occurrence of an Event of Default, to (a) make any payments due under this
Agreement or the Governing Documents, and (b) do any other act or thing that may
be necessary or appropriate to be done in the performance and observance of the
terms hereof.  All payments so made and all things so done and performed by the
Lender shall be as effective to prevent or cure any Event of Default under this
Agreement and the Governing Documents as they would have been if made, done and
performed by the Project Partnerships, and each Project Partnership agrees to
accept such performance, payment and cure.  Each Project Partnership agrees to
make all payments (if any) to be made by it to a defaulting Project Partnership
directly to the Lender upon receipt of the Lender's written instructions to that
effect.

          14.3.  As used herein, the term (a) "Lender" means U.S. Bank Trust
National Association, not in its individual capacity but solely as trustee and
collateral agent pursuant to the Indenture of even date herewith (the
"Indenture") among it, Caithness Coso Funding Corp., as issuer, and the Project
Partnerships as borrowers and guarantors, and its agents, representatives,
successors and assigns, (b) "Lender's Lien" means the hypothecation, mortgage or
pledge of all or any portion of the Project Partnership Assets (as that term is
defined below) to the Lender as security for the repayment of the indebtedness
and performance of the obligations under the Indenture, the Guarantees or any
other Financing Document (as those terms are defined in the Indenture) and (c)
"Project Partnership Assets" means, collectively, a Project Partnership's right,
title and interest in and under this Agreement and the Governing

                                       13


Documents and in and to the Property, the Cotenancy Assets and any Individually-
Owned Assets.

          14.4.  Each Project Partnership agrees for the benefit of the Lender
that it will not, without the prior written consent of the Lender (which consent
shall be given or withheld on the basis of the documents governing the
relationship between the Lender and such Project Partnership): (a) amend or
modify, or take any action causing, consenting to or accepting the amendment or
modification of this Agreement or the Governing Documents, if such amendment or
modification would reduce the rights or remedies of the Lender hereunder or
impair or reduce the security for the Lender's Lien, or (b) cancel, terminate or
suspend, or take any action causing, consenting to or accepting the
cancellation, termination or suspension of, this Agreement or the Governing
Documents.

          14.5.  Each Project Partnership shall deliver to the Lender a
duplicate copy of any and all Notices of Default that it may from time to time
deliver to a defaulting Project Partnership hereunder or under the Governing
Documents, and such copies shall be delivered to the Lender at the same time
such Notices of Default are delivered to such defaulting Project Partnership.
No such Notice of Default shall be deemed to have been given to a defaulting
Project Partnership hereunder unless and until a copy thereof shall have been
given to the Lender.

          14.6.  Upon a defaulting Project Partnership's failure to cure any
Event of Default hereunder or under any Governing Document within the time
provided in Section 13.1 hereof, then the Lender shall have an additional sixty
(60) days thereafter to cure such Event of Default; provided, however, that if
such Event of Default cannot reasonably be cured within such additional sixty
(60) day period, then the Lender shall have such additional time to cure such
Event of Default as may be reasonably necessary.  Any Event of Default that
cannot be cured by the Lender shall nevertheless be deemed to have been cured
and remedied if (a) on or before sixty (60) days after receiving such Notice of
Default, the Lender shall have acquired the defaulting Project Partnership's
then-remaining Project Partnership Assets, or shall have commenced foreclosure
or other appropriate proceedings for such purposes and shall be prosecuting such
proceedings to completion with commercially reasonable diligence, (b) the Lender
shall have fully cured within such sixty (60) day period any failure on the part
of the defaulting Project Partnership to perform its monetary obligations
hereunder and shall thereafter continue to perform such monetary obligations and
(c) after obtaining the defaulting Project Partnership's then-remaining Project
Partnership Assets, the Lender commences performance of the obligations of the
defaulting Project Partnership hereunder.  All rights of the Project
Partnerships to terminate this Agreement as a result of the occurrence of an
Event of Default hereunder shall be expressly conditioned upon (i) the Lender
having first received a copy of the Notice of Default as and when provided in
Section 14.5 hereof and (ii) the Lender having failed to cure the Event of
Default or acquire possession of the defaulting Project Partnership's Project
Partnership Assets or commence foreclosure or other appropriate proceedings as
set forth, and within the time specified, in this Section 14.6.

          14.7.  If the Lender is prohibited by any process or injunction issued
by, or by reason of any action of, any court having jurisdiction over any
bankruptcy, reorganization, insolvency or other debtor-relief proceeding from
commencing or prosecuting foreclosure or other appropriate proceedings, then the
times specified in Section 14.6 hereof for commencing or

                                       14


prosecuting such foreclosure or other proceedings shall be extended for the
period of such prohibition; provided, however, that the Lender shall have fully
cured, within the time specified in Section 14.6 hereof, any failure on the part
of the defaulting Project Partnership to perform its monetary obligations
hereunder, and shall thereafter continue to perform such monetary obligations
when and as due hereunder.

          14.8.  The transfer of a defaulting Project Partnership's Project
Partnership Assets or any part thereof to the Lender and/or to one or more
purchasers or grantees (a) at a foreclosure sale by judicial or nonjudicial
foreclosure and sale, (b) by a conveyance in lieu of foreclosure or (c) by any
other assignment or conveyance, including, without limitation, by the Lender or
such other purchaser(s) or grantee(s) following foreclosure and sale, or as a
result of any other legal proceeding, shall not require the consent of the other
Project Partnerships, and such other Project Partnerships agree that upon such
foreclosure, sale, conveyance, assignment or other proceeding, they shall
recognize the Lender or such other purchaser(s) or grantee(s) as the successor
to the defaulting Project Partnership under this Agreement and the Governing
Documents; provided, however, that, subject to Section 14.10 hereof, the Lender
or such purchaser(s) or grantee(s) assumes the obligations of the defaulting
Project Partnership under this Agreement, the Leases and/or the Exchange
Agreement and pays all amounts in arrears due from the defaulting Project
Partnership to the other Project Partnerships hereunder.

          14.9.  In the event that this Agreement or the Exchange Agreement is
rejected by a trustee or debtor-in-possession in any bankruptcy or insolvency
proceeding, or if this Agreement or the Exchange Agreement is terminated for any
reason other than an Event of Default which could have been but was not cured by
a Lender as provided in this Section 14, and if, within sixty (60) days after
receiving notice of such rejection or termination, the Lender shall so request,
then, so long as the Lender has cured any monetary default by the defaulting
Project Partnership and is making commercially reasonable efforts to cure any
non-monetary default by the defaulting Project Partnership as provided herein,
the other Project Partnerships shall execute and deliver to the Lender or its
designee one or more new agreements, which new agreement(s) shall be on the same
terms and conditions as this Agreement and/or the Exchange Agreement (as the
case may be), for the remaining term of this Agreement and/or the Exchange
Agreement (as the case may be) before giving effect to such rejection or
termination.

          14.10.  The Lender or any such purchaser(s) or grantee(s) shall not
have any duty, obligation or liability under this Agreement or the Governing
Documents prior to the time of its entry into physical possession of a Project
or its commencement of performance of a defaulting Project Partnership's
obligations under this Agreement or the Governing Documents or under a new
agreement entered into as provided in Section 14.9 hereof, and shall not
otherwise be required to perform (or be subject to any defenses or offsets by
reason of) any defaulting Project Partnership's other obligations under this
Agreement or the Governing Documents that were unperformed at such time.  In the
event that the Lender elects to perform a defaulting Project Partnership's
obligations under this Agreement and/or the Governing Documents, or to enter
into a new agreement as provided in Section 14.9 hereof, then the Lender shall
not have any personal liability to any Project Partnership for the performance
of such obligations, and the sole recourse of such Project Partnerships in
seeking the enforcement of such obligations shall be to the Lender's interest in
the defaulting Project Partnership's Project Partnership Assets.  In the event
that the Lender assigns its interest in this Agreement, the Governing Documents
or a new

                                       15


agreement entered into pursuant to Section 14.9 hereof to any person or entity,
then the Lender shall be released from any further liability hereunder.

          14.11.  The Project Partnerships shall cooperate in including herein,
by suitable amendment from time to time, any provision which the Lender
reasonably requests for the purpose of implementing or amending the provisions
of this Section 14 or affording the Lender reasonable protection of its Lender's
Lien in the event of a default by a Project Partnership; provided, however, that
the Project Partnerships shall not be required to include herein any additional
term or provision which materially impairs the rights of the non-defaulting
Project Partnerships under this Agreement.  Each of the Project Partnerships
agrees to execute and deliver (and to acknowledge, if necessary for recording
purposes) any document or instrument reasonably necessary to give effect to any
such provision.

          14.12.  Each of the Project Partnerships and the Operator shall, upon
not less than ten (10) days prior written notice from a requesting Project
Partnership or from the Lender, execute an estoppel certificate (a) certifying
that this Agreement and the Governing Documents are in full force and effect and
have not been modified, (b) certifying that to the best of such Project
Partnership's knowledge there are no uncured events of default under this
Agreement or the Governing Documents (or, if any such uncured events of default
exist, stating with particularity the nature thereof) and (c) containing any
other certifications as may reasonably be requested.  Any such statements may be
conclusively relied upon by the requesting Project Partnership or the Lender.
The failure of a Project Partnership or the Operator to deliver such statement
within such time shall be conclusive upon such Project Partnership and the
Operator that (i) this Agreement and the Governing Documents are in full force
and effect and have not been modified and (ii) there are no uncured events of
default by any Project Partnership under this Agreement or the Governing
Documents.

          14.13.  Each Project Partnership agrees to have its successor under
this Agreement and the Governing Documents assume in writing its obligations
under this Agreement and the Governing Documents; provided, however, that
nothing contained herein shall be deemed a consent by the Lender to any
assignment that is prohibited, or to which the Lender may withhold its consent,
under the Financing Documents (as that term is defined in the Indenture).

          14.14.  At the Lender's option, this Agreement, the Governing
Documents or any thereof shall be subordinated to the Lender's Lien and/or to
any encumbrance now of record or recorded after the date of this Agreement.
Further, at the Lender's option, the lien of any mortgage, deed of trust or
security interest hereafter encumbering all or any portion of a Project
Partnership's Project Partnership Assets shall be subordinated to this
Agreement, the Governing Documents or any thereof, and/or to the Lender's Lien.

          14.15.  All insurance and condemnation proceeds payable to the Project
Partnerships under this Agreement or any of the Governing Documents as a result
of damage, destruction or condemnation of any portion of the Property shall be
paid to the Lender for handling in accordance with the terms of the Financing
Documents.  The Project Partnerships shall not enter into any settlement or
adjustment relating to such proceeds without the prior written consent of the
Lender.

                                       16


          14.16.  The Project Partnerships agree that, upon the occurrence of an
event of default hereunder, under a Governing Document or under any of the
Financing Documents, the Lender or a receiver shall have the right to enter,
possess and use the Project Partnership Assets at such reasonable times and
manner as are necessary or desirable to effectuate the remedies and enforce the
rights of the Lender under the Financing Documents.

          14.17.  This Agreement and the Conveyance Documents shall be binding
upon the successors and assigns of the Project Partnerships and shall inure,
together with the rights and remedies of the Lender hereunder, to the benefit of
the Project Partnerships and the Lender and their respective successors,
transferees and assigns.  Each Project Partnership agrees to confirm such
continuing obligation in writing upon the reasonable request of any other
Project Partnership, the Lender or their respective successors, transferees or
assigns.

     15   GENERAL PROVISIONS

          15.1 Effect of This Agreement.  This Agreement shall automatically
attach and apply (a) to the Leases and the CLC Pre-Existing Assets at such time

Assets at such time as the Operator Assignment is completed, in each case
without the need for any other documentation or consent by or from any party
hereto; and, at such time, each Project Partnership's rights in and to all of
the Cotenancy Assets, the Property and Individually-Owned Assets shall be

indemnify, defend and hold harmless the other Project Partnerships (each, an
"Indemnified Project Partnership") from and against any and all losses, damages,
liabilities, claims, judgments, liens, penalties, costs and expenses, including,
without limitation, reasonable attorneys' and consultants' fees, which may be
imposed upon or incurred by such the Indemnified Project Partnership or asserted
against such Indemnified Project Partnership by any third person or entity in
connection with (a) any acts, omissions, operations or activities of the
Indemnifying Project Partnership on or in connection with (i) the Cotenancy
Assets or the Property or (ii) such Indemnifying Project Partnership's
Individually-Owned Assets and (b) any Event of Default or Default by the
Indemnifying Project Partnership in the performance of its obligations under
this Agreement.

                15.2.2 The Project Partnerships acknowledge that when CLC
acquired the Leases from the Los Angeles Department of Water and Power
("LADWP"), it made certain covenants and gave certain indemnities to LADWP.
Without limiting the generality of the Lease Assignment, the Project
Partnerships hereby agree to abide by such covenants and to assume such
indemnities in proportion to their respective Interests.

Acquisition Agreement and the Governing Documents collectively contain all
agreements of the Project Partnerships with respect to the subject matter
hereof, and all other prior or contemporaneous agreements, understandings,

further force or effect, and are superseded hereby.

          15.8 Severability.  The invalidity or unenforceability of any
provision hereof as determined by a court of competent jurisdiction shall in no
way affect the validity and enforceability of any other provision hereof; and in
the event that any part or provision of this Agreement shall be determined by a
court of competent jurisdiction to be invalid or unenforceable, then the
