     The Coso projects  consist of three 80 MW geothermal  power plants,  called
Navy I, BLM and Navy II, their transmission lines,  wells,  gathering system and
other  related  facilities.  Coso Finance  Partners  owns Navy I and its related
facilities,  Coso Energy Developers owns BLM and its related facilities and Coso
Power Developers owns Navy II and its related facilities. Coso Finance Partners,
Coso Energy Developers and Power Developers are collectively  referred to as the
"Coso Partnerships" and are registrants.

     Caithness Coso Funding Corp.  ("Funding  Corp."),  also a registrant,  is a
single-purpose  Delaware  Corporation  formed  to issue  securities  for its own
account and act as an agent on behalf of the Coso Partnerships. On May 28, 1999,
Funding  Corp.  sold $413 million of senior  secured notes due December 15, 2009
(the  "Existing  Notes"),  of which  approximately  $208  million  is  currently
outstanding.  Pursuant to separate credit  agreements  between Funding Corp. and
each of the  Coso  Partnerships,  the net  proceeds  from  the  offering  of the
Existing Notes by Funding Corp. were loaned to the Coso Partnerships.


Section 1 - Registrants Business and Operations

Item 1.01 Entry into a Material Definitive Agreement

     On August 5, 2005,  Funding  Corp.  issued $375  million of senior  secured
bonds due June 15, 2019 and $90 million of  subordinated  secured notes due June
15, 2014 (collectively, the "Securities"). The senior bonds were issued pursuant
to an  Indenture  dated  August 5, 2005  between  Funding  Corp.  and U.S.  Bank
National  Association,  as trustee (the "Senior Indenture").  The Securities are
secured by the assets of Funding Corp. and the Coso  Partnerships and pledges of
the Coso  Partnerships'  interests by the owners thereof,  and are guaranteed by
each of the Coso Partnerships pursuant to security and guarantee agreements.

Item 1.02 Termination of a Material Definitive Agreement

     The proceeds of the  Securities  will be put into an escrow account for the
benefit of the holders of the Existing Notes, and on approximately  September 6,
2005,  the proceeds of the escrow account will be released to the holders of the
Existing Notes to repay the Existing Notes in full.

     Effective  August 5, 2005,  under the terms of the Indenture (the "Existing
Indenture") of the Existing  Notes,  the covenants of Funding Corp. and the Coso
Partnerships  will be defeased,  and the related security  agreements and pledge
agreements of Funding Corp. and the Coso Partnerships pertaining to the Existing
Notes will be deemed to be satisfied  in full and will no longer be  enforceable
against Funding Corp. or the Coso Partnerships.


Section 2 - Financial Information

Item 2.03  Creation of a Direct Financial Obligation or an Obligation Under an
           Off-Balance Sheet Arrangement of a Registrant

     On August 5, 2005,  Funding Corp.  issued the Securities that constitutes a
direct  financial  obligation of Funding Corp.  The  Securities are secured by a
first  priority lien (for senior  secured  bonds) and a  subordinated  lien (for
subordinated  secured notes) on the assets of Funding Corp. and on the assets of
the  Coso  Partnerships   pursuant  to  separate  guarantees.   Such  guarantees
constitute  obligations  under an off-balance  balance sheet  arrangement of the
Coso Partnerships and are joint and several, unconditional guarantees of payment
of the Securities.

Item 2.04  Triggering Events That Accelerate or Increase a Direct Financial
           Obligation or an Obligation Under an Off-Balance Sheet Arrangement

     The  issuance of the  Securities  triggers  acceleration  of the  principal
amount of the  Existing  Notes  under the  Existing  Indenture.  Therefore,  the
proceeds from the issuance of the Securities  will be placed in escrow on August
5, 2005, for the benefit of the holders of the Existing  Notes.  Under the terms
of the Existing Indenture,  the covenants prohibiting the issuance of the Senior
Bonds and Subordinated Notes will be defeased on August 5, 2005, and the related
security  agreements  and  pledge  agreements  of  Funding  Corp.  and the  Coso
Partnerships  will be  deemed  to be  satisfied  in full and will no  longer  be
enforceable against Funding Corp. or the Coso Partnerships.  Upon release of the
funds  held in escrow to the  holders  of the  Existing  Notes on  approximately
September 6, 2005,  the Existing Notes will be repaid in full and will no longer
be enforceable against Funding Corp. or the Coso Partnerships,  and the Existing
Indenture and related  guarantees of the Coso  Partnerships will be deemed to be
satisfied in full and will no longer be enforceable against Funding Corp. or the
Coso Partnerships.
