                   NOTES TO THE UNAUDITED FINANCIAL STATEMENTS
                             (Dollars in thousands)


(1)      Organization and Operations

Caithness Coso Funding Corp.  (Funding  Corp.),  which was incorporated on April
22,  1999,  is a  single-purpose  Delaware  corporation  formed to issue  senior
secured  notes  (Notes) for its own account and as an agent  acting on behalf of
Coso  Finance  Partners  (CFP),  Coso Energy  Developers  (CED),  and Coso Power
Developers  (CPD),  collectively,   the  "Partnerships."  The  Partnerships  are
California general Partnerships.

On May 28, 1999,  Funding  Corp.  sold  $413,000 of Notes.  Pursuant to separate
credit agreements  between Funding Corp. and each Partnership,  the net proceeds
from the offering Notes were loaned to the Partnerships. Payment of the Notes is
provided for by payments made by the Partnerships under their respective project
loans.  Funding Corp. has no material  assets other than the project loans,  and
does not conduct any  operations  apart from having  issued the Notes and making
the project loans to the Partnerships.

(2)      Basis of Presentation

The accompanying  unaudited condensed financial statements have been prepared in
accordance with accounting principles generally accepted in the United States of
America for interim financial information.  Accordingly, certain information and
footnote  disclosures  normally  included in  financial  statements  prepared in
accordance with accounting principles generally accepted in the United States of
America  have been  condensed  or omitted  pursuant  to such  rules.  Management
believes that the disclosures are adequate to make the information presented not
misleading when read in conjunction with the financial  statements and the notes
thereto in the audited  financial  statements  for the year ended  December  31,
2003.

The preparation of unaudited financial  statements in accordance with accounting
principles  generally  accepted in the United States of America requires Funding
Corp.  to make certain  estimates  and  assumptions  for the  reporting  periods
covered by the financial statements.  These estimates and assumptions affect the
reported  amounts  of  assets,  liabilities,  income  and  expenses  during  the
reporting  period.  Actual  results  could  differ  from  these  estimates.  The
financial information herein presented reflects all adjustments, consisting only
of normal  recurring  adjustments,  which are,  in the  opinion  of  management,
necessary for a fair statement of the results for interim periods presented. The
results for the interim periods are not necessarily  indicative of results to be
expected for the full year.

                                 AND SUBSIDIARY
                   NOTES TO THE UNAUDITED FINANCIAL STATEMENTS
                             (Dollars in thousands)


(1)      Organization and Operation

Coso Finance Partners (CFP), a general partnership,  is engaged in the operation
of an 80 MW power  generation  facility  located  at the  China  Lake  Naval Air
Weapons Station,  China Lake California.  CFP sells all electricity  produced to
Southern  California  Edison  (Edison) under a 24-year power  purchase  contract
expiring in 2011.

(2)      Basis of Presentation

The accompanying  unaudited condensed financial statements have been prepared in
accordance with accounting principles generally accepted in the United States of
America for interim financial information.  Accordingly, certain information and
footnote  disclosures  normally  included in  financial  statements  prepared in
accordance with accounting principles generally accepted in the United States of
America  have been  condensed  or omitted  pursuant  to such  rules.  Management
believes that the disclosures are adequate to make the information presented not
misleading when read in conjunction with the financial  statements and the notes
thereto in the audited  financial  statements  for the year ended  December  31,
2003.

The preparation of unaudited financial  statements in accordance with accounting
principles  generally  accepted in the United States of America  requires CFP to
make certain  estimates and assumptions for the reporting periods covered by the
financial  statements.  These  estimates  and  assumptions  affect the  reported
amounts of assets,  liabilities,  revenues  and  expenses  during the  reporting
period.  Actual  results  could  differ  from  these  estimates.  The  financial
information herein presented reflects all adjustments, consisting only of normal
recurring adjustments, which are, in the opinion of management,  necessary for a
fair statement of the results for interim periods presented. The results for the
interim periods are not necessarily indicative of results to be expected for the
full year. CFP has experienced  significant quarterly  fluctuations in operating
results and it expects that these fluctuations in energy revenues,  expenses and
net income will continue.

The data for the consolidated  balance sheets presented herein for June 30, 2004
and  December  31, 2003 were derived  from CFP's  financial  statements  for the
interim   period  and  fiscal  year  then  ended  and  includes  the  effect  of
consolidating  New  CLPSI  Company,  LLC  (CLPSI),  but  does  not  include  all
disclosures  required by accounting  principles generally accepted in the United
States of America.

(3)      New Accounting Pronouncements

The consolidated financial statements of CFP include the accounts of CPLSI, as a
result  of  the  adoption  of  Financial   Accounting   Standards  Board  (FASB)
Interpretation No. 46. (FIN 46)  (Consolidation of Variable Interest  Entities),
an  interpretation  of  Accounting  Research  Bulletin  No. 51. FIN 46  required
certain variable interest entities to be consolidated by the primary beneficiary
of the entity even though the equity  investors do not have the  characteristics
of a controlling  financial  interest,  or do not have sufficient equity at risk
for the  entity  to  finance  its  activities  without  additional  subordinated
financial  support from other parties.  In December 2003, the FASB issued FIN 46
(R),  which  clarified and replaced FIN 46 that  required all variable  interest
entities,  regardless of when they were created to be evaluated under FIN 46 (R)
no later  than the  period  ending  March 15,  2004.  An entity  is  subject  to
consolidation  according  to the  provisions  of FIN 46 (R) if, by  design,  the
following  conditions exist.  As a group, the  holders of the  equity investment

                                       11

at risk lack any one of the  following  three  characteristics  of a controlling
financial  interest:  (1) the direct or indirect ability to make decisions about
an  entity's  activities  through  voting  rights  or  similar  rights;  (2) the
obligation to absorb the expected losses of the entity if they occur; or (3) the
right to receive the expected  residual returns of the entity if they occur. CFP
believes  that  CLPSI,  the  entity  that  holds the  inventory  for Coso  Power
Developers,  Coso Energy  Developer  and CFP is a variable  interest  entity and
under FIN 46 (R) should be consolidated. The inventory, related physical assets,
and payables have been recorded as CFP's assets and  liabilities.  The impact to
CFP's   future   consolidated   statement  of   operations   will  be  increased
depreciation, partially offset by other income.

The  consolidated  financial  statements  related  to prior  periods  have  been
restated to consolidate the accounts of CLPSI as a direct result of the adoption
of FIN 46 (R). There was no cumulative  effect recorded upon the adoption of the
Interpretation.

(4)      Accounts Receivable and Revenue Recognition

Accounts receivable primarily consist of receivables from Edison for electricity
delivered  and sold under a power  purchase  contract.  Operating  revenues  are
recognized  as income  during the period in which  electricity  is  delivered to
Edison.

(5)      Reclassifications

Certain  balances  in prior  years  have been  reclassified  to  conform  to the
presentation adopted in the current year.

                   NOTES TO THE UNAUDITED FINANCIAL STATEMENTS
                             (Dollars in thousands)


(1)      Organization and Operation

Coso Energy Developers (CED), a general partnership, is engaged in the operation
of an 80 MW power  generation  facility  located at the Coso Hot Springs,  China
Lake  California.  CED sells all  electricity  produced to  Southern  California
Edison (Edison) under a 30-year power purchase contract expiring in 2019.

(2)      Basis of Presentation

The accompanying  unaudited condensed financial statements have been prepared in
accordance with accounting principles generally accepted in the United States of
America for interim financial information.  Accordingly, certain information and
footnote  disclosures  normally  included in  financial  statements  prepared in
accordance with accounting principles generally accepted in the United States of
America  have been  condensed  or omitted  pursuant  to such  rules.  Management
believes that the disclosures are adequate to make the information presented not
misleading when read in conjunction with the financial  statements and the notes
thereto in the audited  financial  statements  for the year ended  December  31,
2003.

The preparation of unaudited financial  statements in accordance with accounting
principles  generally  accepted in the United States of America  requires CED to
make certain  estimates and assumptions for the reporting periods covered by the
financial  statements.  These  estimates  and  assumptions  affect the  reported
amounts of assets,  liabilities,  revenues  and  expenses  during the  reporting
period.  Actual  results  could  differ  from  these  estimates.  The  financial
information herein presented reflects all adjustments, consisting only of normal
recurring adjustments, which are, in the opinion of management,  necessary for a
fair statement of the results for interim periods presented. The results for the
interim periods are not necessarily indicative of results to be expected for the
full year. CED has experienced  significant quarterly  fluctuations in operating
results and it expects that these fluctuations in energy revenues,  expenses and
net income will continue.

(3)      Accounts Receivable and Revenue Recognition

Accounts receivable primarily consist of receivables from Edison for electricity
delivered  and sold under a power  purchase  contract.  Operating  revenues  are
recognized  as income  during the period in which  electricity  is  delivered to
Edison.

(4)      Reclassifications

Certain  balances  in prior  years  have been  reclassified  to  conform  to the
presentation adopted in the current year.

Lake  California.  CPD sells all  electricity  produced to  Southern  California
Edison (Edison) under a 20-year power purchase contract expiring in 2010.

(2)      Basis of Presentation

The accompanying  unaudited condensed financial statements have been prepared in
accordance with accounting principles generally accepted in the United States of
America for interim financial information.  Accordingly, certain information and
footnote  disclosures  normally  included in  financial  statements  prepared in
accordance with accounting principles generally accepted in the United States of

believes that the disclosures are adequate to make the information presented not

thereto in the audited  financial  statements  for the year ended  December  31,

The preparation of unaudited financial  statements in accordance with accounting
principles  generally  accepted in the United States of America  requires CPD to
make certain  estimates and assumptions for the reporting periods covered by the
financial  statements.  These  estimates  and  assumptions  affect the  reported
amounts of assets,  liabilities,  revenues  and  expenses  during the  reporting
period.  Actual  results  could  differ  from  these  estimates.  The  financial
information herein presented reflects all adjustments, consisting only of normal
recurring adjustments, which are, in the opinion of management,  necessary for a
fair statement of the results for interim periods presented. The results for the
interim periods are not necessarily indicative of results to be expected for the
full year. CPD has experienced  significant quarterly  fluctuations in operating
results and it expects that these fluctuations in energy revenues,  expenses and
net income will continue.

The data for the consolidated  balance sheets presented herein for June 30, 2004
and  December  31, 2003 were derived  from CPD's  financial  statements  for the
interim   period  and  fiscal  year  then  ended  and  includes  the  effect  of
consolidating  Coso Transmission Line Partners (CTLP),  but does not include all
disclosures  required by accounting  principles generally accepted in the United
States of America.

(3)      New Accounting Pronouncements

The consolidated  financial statements of CPD include the accounts of CTLP, as a
result  of  the  adoption  of  Financial   Accounting   Standards  Board  (FASB)
Interpretation No. 46. (FIN 46)  (Consolidation of Variable Interest  Entities),
an  interpretation  of  Accounting  Research  Bulletin  No. 51. FIN 46  required
certain variable interest entities to be consolidated by the primary beneficiary
of the entity even though the equity  investors do not have the  characteristics
of a controlling  financial  interest,  or do not have sufficient equity at risk
for the  entity  to  finance  its  activities  without  additional  subordinated
financial  support from other parties.  In December 2003, the FASB issued FIN 46
(R),  which  clarified and replaced FIN 46 that  required all variable  interest
entities,  regardless of when they were created to be evaluated under FIN 46 (R)
no  later  than  the period  ending  March 15, 2004.  An  entity  is  subject to

                                       20

consolidation  according  to the  provisions  of FIN 46 (R) if, by  design,  the
following  conditions exist. As a group, the holders of the equity investment at
risk  lack  any one of the  following  three  characteristics  of a  controlling
financial  interest:  (1) the direct or indirect ability to make decisions about
an  entity's  activities  through  voting  rights  or  similar  rights;  (2) the
obligation to absorb the expected losses of the entity if they occur; or (3) the
right to receive the expected  residual returns of the entity if they occur. CPD
believes that CTLP, the entity that holds additional  transmission equipment for
Coso Energy  Developers and CPD is a variable  interest  entity and under FIN 46
(R)  should be  consolidated.  The  additional  transmission  equipment  will be
recorded as CPD's  assets.  The impact to CPD's future  statement of  operations
will be increased depreciation, partially offset by other income.

The  consolidated  financial  statements  related  to prior  periods  have  been
restated to consolidate  the accounts of CTLP as a direct result of the adoption
of FIN 46 (R). There was no cumulative  effect recorded upon the adoption of the
Interpretation.

(4)      Accounts Receivable and Revenue Recognition

Accounts receivable primarily consist of receivables from Edison for electricity
delivered  and sold under a power  purchase  contract.  Operating  revenues  are
recognized  as income  during the period in which  electricity  is  delivered to
Edison.

(5)      Reclassifications

Certain  balances  in prior  years  have been  reclassified  to  conform  to the
presentation adopted in the current year.

                                       21

General

     Each  Coso  Partnership  owns  an  80MW  geothermal  power  plant,  and its
respective  transmission  lines,  wells,  gathering  systems  and other  related
facilities.  The Coso  Partnerships  are located  near one another at the United
States  Naval  Air  Weapons  Center  at  China  Lake,  California.  The  Navy  I
Partnership owns Navy I and its related facilities. The BLM Partnership owns BLM
and its related facilities. The Navy II Partnership owns Navy II and its related
facilities.

     Each Coso partnership  sells 100% of the electrical energy generated at its
plant to Edison under a long-term Standard Offer No.4 power purchase  agreement.
Each power purchase agreement expires after the final maturity date of the 9.05%
Series B Senior Secured Notes (Notes) issued by Funding Corp.

     Each Coso partnership is entitled to the following payments under its power
purchase agreement:

*    Capacity payments for being able to produce  electricity at certain levels.
     Capacity  payments  are fixed  throughout  the life of each power  purchase
     agreement;

*    Capacity  bonus  payments  if the  Coso  partnership  is  able  to  produce
     electricity  above a specified  level.  The maximum  annual  capacity bonus
     payment  available is also fixed throughout the life of each power purchase
     agreement; and

*    Energy  payments  which are based on the  amount  of  electricity  the Coso
     Partnership's plant actually produces.

     Energy  payments were fixed for the first ten years of firm operation under
each power purchase  agreement.  After the first ten years of firm operation and
until  January 1, 2002,  Edison  made energy  payments to the Coso  Partnerships
based on its avoided cost of energy. Edison's avoided cost of energy is Edison's
cost to generate  electricity if Edison were to produce it itself or buy it from
another power producer rather than buy it from the Coso Partnerships.  The fixed
energy price period expired in August 1997 for the Navy I Partnership,  in March
1999 for the BLM Partnership and in January 2000 for the Navy II Partnership.

     Edison entered into an agreement  (Agreement) with the Coso Partnerships on
June 19, 2001 that  addressed  renewable  energy  pricing and issues  concerning
California's  energy crisis.  The  Agreement,  which was amended on November 30,
2001,  established May 1, 2002 as the date the Coso Partnerships began receiving
a fixed energy rate of 5.37 cents per kWh for five (5) years in lieu of the rate
calculated based on the avoided cost of energy. This Agreement was challenged in
the federal courts.  The California State Supreme Court found that no state laws
were  violated,  and the United  States  Court of Appeals for the Ninth  Circuit
(Ninth  Circuit)  affirmed  this  judgment.  As a result of the Ninth  Circuit's
decision, the Agreements remain in full force and effect.

     After the five year period  expires in April 2007,  Edison will be required
to make energy  payments to the Coso  Partnerships  based on its avoided cost of
energy until each  partnership's  power purchase  agreement  expires.  The power
purchase  agreement for the Navy I Partnership  will expire in August 2011,  the
power purchase  agreement for the BLM Partnership will expire in March 2019, and
the power purchase  agreement for the Navy II Partnership will expire in January
2010. The California Public Utilities  Commission (CPUC) has initiated a hearing
to re-evaluate  the methodology of calculating the avoided cost of energy in the
future.  It is not possible to predict with  accuracy the likely level of future
avoided cost of energy prices.

                                       22

     Edison  filed a  petition  for a writ of  review  of a  January  2001  CPUC
decision,  claiming  that the  "floor"  line loss  factor of 0.95 for  renewable
generators  violated the Public Utility Regulatory Policies Act of 1978 (PURPA).
Subsequently,  the  California  Court of Appeals issued a decision on August 20,
2002 in response to the writs  affirming the January 2001 CPUC decision,  except
for the 0.95  "floor",  which it rejected as an abuse of discretion by the CPUC.
While this matter was appealed to the California Supreme Court, the petition for
review was denied.  The Coso  Partnerships  are currently  evaluating  potential
actions to redress this issue.  Their Agreements set the line loss factor at 1.0
for all energy sold between May 2002 through April 2007.  After April 2007,  the
Coso  Partnerships  will have a line loss  factor of less than 1.0,  effectively
decreasing revenues if Edison's challenge to the CPUC ruling stands.

     The  Coso  Partnerships   cannot  predict  whether  any  subsequent  action
regarding this matter will be successful.

     In 1994, the Coso Partnerships  implemented a steam-sharing  program, under
the Coso Geothermal Exchange Agreement. The purpose of the steam-sharing program
is to enhance the management of the Coso geothermal resource and to optimize the
resource's overall benefits to the Coso Partnerships by transferring steam among
the  Coso  Partnerships.  Under  the  steam  sharing  program,  the  partnership
receiving the steam transfer  splits revenue earned from  electricity  generated
with the partnership that transferred the steam.

     The Coso  Partnerships  are required to make  royalty  payments to the U.S.
Navy and the Bureau of Land  Management.  The Navy I Partnership  pays a royalty
for Unit I through  reimbursement  of  electricity  supplied to the U.S. Navy by
Edison from  electricity  generated at the Navy I plant.  The  reimbursement  is
based on a  pricing  formula  that is  included  in the U.S.  Navy  Contract  as
amended.  This formula is primarily based on the tariff rates charged by Edison,
which were increased in 2001 by the CPUC, and is subject to future revision.  On
July 10, 2003, the CPUC adopted a settlement between Edison and other parties to
lower retail electric rates  effective as of August 1, 2003.  These rates are in
effect for one year,  after which new rates will be  established  in  accordance
with CPUC guidelines. Indices utilized in the calculation of the royalties under
the Navy I Partnership Unit 1 contract remained unchanged  historically based on
an agreement between the U.S. Navy and the Navy I Partnership.  In November 2001
and October 2002,  modifications to the calculation of the reimbursement pricing
formula were made to the U.S. Navy Contract.  The parties have currently  agreed
to a  replacement  index  and  true-up  calculation  in  favor  of  the  Navy  I
Partnership. For Units 2 and 3, the Navy I Partnership's royalty expense paid to
the U.S.  Navy is a fixed  percentage  of  electricity  sales  which  was 15% of
revenue received by the Navy I Partnership through 2003 and increased to 20% for
2004 through  2009. In addition,  the Navy I Partnership  is required to pay the
U.S. Navy $25.0 million in December  2009,  the date its contract  expires.  The
payment is secured by funds placed on deposit monthly,  which funds plus accrued
interest are  anticipated to aggregate  $25.0 million by the expiration  date of
the contract. Currently, the monthly amount deposited is approximately $111,000.
The BLM  Partnerships  geothermal lease initially had a term of ten years ending
in 1998 with automatic  extensions until October 31, 2035, so long as geothermal
steam  is  commercially  produced.  The  royalty  paid  to the  Bureau  of  Land
Management  is 10% of the net  value of steam  produced  based on a  calculation
known as the netback which is estimated and paid monthly with an annual  true-up
after year-end. The Navy II partnership pays a royalty to the U.S. Navy based on
a fixed  percentage of electricity  sales to Edison.  The royalty rate is 18% of
electricity  sales through 2004 and will increase to 20% from 2005 through 2010.
The Coso  Partnerships  also pay other royalties,  at various rates which in the
aggregate are not material.

     Funding  Corp.  is  a  special  purpose  corporation  and  a  wholly  owned
subsidiary  of the Coso  Partnerships.  It was formed for the purpose of issuing
the senior  secured  notes (Notes) on behalf of the Coso  Partnerships  who have
jointly, severally, and unconditionally guaranteed repayment of the Notes.

                                       23

     On May 28, 1999,  Funding Corp.  issued $110.0  million of 6.80% Notes that
were due in 2001,  and were paid off on December 15, 2001, and $303.0 million of
9.05%  Notes due in 2009.  The  proceeds  from the Notes were loaned to the Coso
Partnerships  and are payable to Funding  Corp from  payments of  principal  and
interest on the Notes. Funding Corp. does not conduct any other operations apart
from serving as the issuer of the Notes.

     Under the  depository  agreement  with the trustee for the Notes,  the Coso
Partnerships  established  accounts with a depository and pledged those accounts
as security for the benefit of the holders of the Notes.  All amounts  deposited
with the depository are, at the direction of the Coso Partnerships,  invested by
the depository in permitted investments. All revenues or other proceeds actually
received  by the Coso  Partnerships  are  deposited  in a  revenue  account  and
withdrawn upon receipt by the depository of a certificate from the relevant Coso
Partnerships  detailing  the  amounts  to be paid from  funds in its  respective
revenue account.


Capacity Utilization

     For purposes of consistency in financial  presentation,  the plant capacity
factor for each of the Coso  Partnerships is based on a nominal  capacity amount
of 80MW (240MW in the aggregate).  The Coso  Partnerships have a gross operating
capacity  that  allows  for the  production  of  electricity  in excess of their
nominal capacity  amounts.  Utilization of this operating margin is based upon a
number of factors and can be expected to vary  throughout  the year under normal
operating conditions.

     The following  data includes the operating  capacity  factor,  capacity and
electricity  production  (in kWh) for each  Coso  Partnership  on a  stand-alone
basis:

</TABLE>

     Total energy production for the Navy I Partnership  decreased for the three
and six-months  ended June 30, 2004 as compared to the same periods in 2003, due
to  curtailments  by Edison for  transmission  line  maintenance.  Total  energy
production for the BLM Partnership  decreased for the three and six-months ended
June 30,  2004 as  compared  to the same  periods  in 2003,  due to wells  being
temporarily shut down while being repaired. Total energy production for the Navy
II  Partnership  increased for the three and  six-months  ended June 30, 2004 as

                                       24

compared to the same periods in 2003, due to the  successful  effort to increase
production  through well  maintenance  and capital  improvements,  including the
enhancement  of existing  production  wells and  additional  steam-field  piping
modifications.   In  an  effort  to  increase  production   overall,   the  Coso
Partnerships  are  working  to  enhance  the  reservoir   through  an  injection
augmentation program,  which is currently in the engineering design phase, aimed
at improving  reservoir  pressure and  minimizing  resource  decline.  The funds
necessary  to  implement  the capital  improvement  program are  available  from
reserves  established  under the Notes and from excess cash flow generated after
debt service.

transfers discussed above.

     Total operating revenues for the Navy I and BLM Partnerships  decreased for
the three and six-months  ended June 30, 2004 as compared to the same periods in
2003  primarily  due to the  decreases in  production,  discussed  above.  Total
operating  revenues  for the Navy II  Partnership  increased  for the  three and
six-months ended June 30, 2004 as compared to the same periods in 2003 primarily
due to the increase in production, discussed above.

     Plant operating  expense consists of labor and related  expenses,  supplies
and maintenance,  property taxes,  insurance,  well workovers and administrative
expense.  The  increases  in  plant  operating  expense  for the  Navy I and BLM
Partnerships  for the  three-months  ended  June  30,  2004,  and  for the  Coso
Partnership  for the  six-months  ended June 30,  2004,  as compared to the same
periods in 2003,  were  primarily  due to  increased  well  workovers in 2004 to
assist in remediating the decline in steam production,  discussed above.

</TABLE>

     Royalty  expense  for the Navy I  Partnership  decreased  for the three and
six-months  ended  June  30,  2004 as  compared  to the  same  periods  in 2003,
primarily  due to a decrease in Unit 1 royalty,  resulting  from reduced  tariff
rates  charged  by  Edison.  The  decrease  was  partially  offset by  increased
royalties  from Units 2 and 3 resulting  from the scheduled  increase in royalty
rate discussed above. Royalty expense for the BLM Partnership  decreased for the
six-months  ended June 30, 2004 as  compared to the same period in 2003,  due to
the current year reconciliation performed under the netback royalty calculation.
Royalty  expense  for the  Navy II  Partnership  increased  for  the  three  and
six-months  ended June 30, 2004 as compared to the same periods in 2003,  due to
the increase in production discussed above.


Depreciation and Amortization

     Depreciation  and  amortization  expense for the Coso  Partnerships for the
three and  six-months  ended June 30, 2004 as  compared  to the same  periods in
2003,  remains  comparable  as older  wells  and  plant  overhauls  being  fully
depreciated during 2003 were replaced with new capital additions in 2004.


Interest and Other Income

     Interest  and  other  income  for the Coso  Partnerships  for the three and
six-months ended June 30, 2004 as compared to the same periods in 2003,  remains
comparable as the rate of return on  investments  remained  consistent for those
periods.


Interest Expense

     Interest  expense  for the Coso  Partnerships  decreased  for the three and
six-months  ended June 30, 2004 as compared to the same periods in 2003,  due to
the reduction in the principal amount of the project loan from Funding Corp.


Liquidity and Capital Resources

     Each of the  Navy I  Partnership,  the  BLM  Partnership  and  the  Navy II
Partnership derive  substantially all of their cash flow from Edison under their
power purchase  agreements and from interest  income earned on funds on deposit.
The Coso  Partnerships  have used their cash primarily for capital  expenditures
for power plant  improvements,  resource and operating  costs,  distributions to
partners and payments with respect to the project loan.

     The Coso  Partnerships  cash flow  obligations  over the next several years
consist of debt service  payments to Funding  Corp.,  as they come due under the
Notes. The Coso  Partnerships  expect to be able to meet these  obligations from
operating cash flow. Historically, any excess cash after debt service has either
been reserved for capital improvements or distributed to the partners.

                                       26

     The Coso  Partnerships  ability to meet their  obligations as they come due
will depend upon the ability of Edison to meet its  obligations  under the terms
of the standard offer No. 4 power purchase agreements and the Coso Partnerships'
ability to continue to generate electricity.  Edison's shortfall in collections,
coupled  with its near  term  capital  requirements,  materially  and  adversely
affected its liquidity during 2000 and 2001. In resolution of that issue, Edison
settled  with the CPUC on  October  2,  2001,  enabling  it to recover in retail
electric rates its historical shortfall in electric purchase costs. On September
23, 2002,  the United  States Court of Appeals for the Ninth  Circuit  issued an
opinion and order on appeal from the district court's stipulated  judgment which
affirmed  the  stipulated  judgment  in part  and  referred  questions  based on
California  state law to the Supreme  Court of  California.  The  appeals  court
stated  that if the  Agreement  violated  California  state law then the appeals
court would be  required to void the  stipulated  judgment.  California  Supreme
Court accepted the Ninth Circuit Court of Appeals  request to address the issues
referred to it in the September 23, 2002 ruling, and subsequently found that the
stipulated  judgment did not violate  state laws.  Consequently,  the  Agreement
remains in full force and effect and it is unknown if any additional appeals are
planned.  Immediately  after  this  settlement,  Edison  and  each  of the  Coso
Partnerships entered into an amendment of their respective Agreement (referenced
above)  pertaining  to past due  obligations.  The  Agreement,  as amended,  was
approved by CPUC in January of 2002,  and  established  the fixed  energy  rates
discussed  above and set payment terms for the past due amounts owed to the Coso
Partnerships by Edison.  Edison's failure to pay its future obligations may have
a material adverse effect on the Coso Partnerships  ability to make debt service
payments to Funding Corp., as they come due under the Notes.

     Net cash from operating activities for the Navy I Partnership increased for
the  six-months  ended June 30,  2004 as  compared  to the same  period in 2003,
primarily due to increased net income and trade  payables  during 2004. Net cash
from operating  activities for the BLM Partnership  decreased for the six-months
ended June 30, 2004 as compared to the same period in 2003,  primarily  due to a
decrease in net income during 2004. Net cash from  operating  activities for the
Navy II Partnership increased for the six-months ended June 30, 2004 as compared
to the same period in 2003, primarily due to increased net income. Net cash used
in investing  activities for the Coso Partnerships  decreased for the six-months
ended  June 30,  2004 as  compared  to the same  period in 2003,  due to reduced
capital expenditures and lower restricted cash requirements  associated with the
Notes  during  2004.  Net  cash  used  in  financing  activities  for  the  Coso
Partnerships increased for the six-months ended June 30, 2004 as compared to the
same period in 2003, primarily due to increased distributions to partners.


Item 3.  Control and Procedures

     The Registrant's  Chief Executive  Officer and Chief Financial Officer (the
Registrant's  principal  executive  officer  and  principal  financial  officer,
respectively)  have  concluded,  based on their  evaluation as of June 30, 2004,
that the design and  operation  of the  Registrant's  "disclosure  controls  and
procedures" (as defined in Rules 13a-15(e) under the Securities  Exchange Act of
1934,  as  amended  (Exchange  Act) are  effective  to ensure  that  information
required to be disclosed by the  Registrant in the reports filed or submitted by
the  Registrant  under the Exchange  Act is  accumulated,  recorded,  processed,
summarized  and  reported  to  the   Registrant's   management,   including  the
Registrant's  principal  executive officer and principal  financial officer,  as
appropriate  to allow timely  decisions  regarding  whether or not disclosure is
required.

     During  the  quarter  ended  June 30,  2004,  there  were no changes in the
Registrant's  "internal  controls over financial  reporting" (as defined in Rule
13a-15(f)  under  the  Exchange  Act)  that  have  materially  affected,  or are
reasonably likely to materially affect, the Registrant's  internal controls over
financial reporting.

                             NOTES TO THE UNAUDITED
                            CONSOLIDATED AND COMBINED
                              FINANCIAL STATEMENTS
                             (Dollars in thousands)

(1)      Basis of Presentation

The accompanying  unaudited  consolidated and combined financial statements were
derived from the stand alone  unaudited  financial  statements of Caithness Coso
Funding Corp., Coso Finance Partners and Subsidiary,  Coso Energy Developers and
Coso Power Developers and Subsidiary (the Coso  Partnerships).  All intercompany
accounts and transactions were eliminated.  This financial  information has been
provided to  facilitate  a more  comprehensive  understanding  of the  financial
position,  operating results and cash flows of the Coso Partnerships as a whole.
The unaudited  consolidated and combined financial  statements should be read in
conjunction with each individual Partnership's unaudited financial statements.

The preparation of unaudited financial  statements in accordance with accounting
principles generally accepted in the United States of America requires the  Coso
Partnerships to make certain estimates and assumptions for the reporting periods
covered by the financial statements.  These estimates and assumptions affect the
reported  amounts of  assets,  liabilities,  revenues  and  expenses  during the
reporting  period.  Actual  results  could  differ  from  these  estimates.  The
financial information herein presented reflects all adjustments, consisting only
of normal  recurring  adjustments,  which are,  in the  opinion  of  management,
necessary for a fair statement of the results for interim periods presented. The
results for the interim periods are not necessarily  indicative of results to be
expected for the full year. The Coso Partnerships  have experienced  significant
quarterly   fluctuations  in  operating   results  and  it  expects  that  these
fluctuations in energy revenues, expenses and net income will continue.

The data for the  consolidated  and combined balance sheets presented herein for
June 30, 2004 and December  31, 2003 were  derived  from the Coso  Partnership's
financial  statements  for the  interim  period and  fiscal  year then ended and
includes the effect of  consolidating  New CLPSI  Company,  LLC (CLPSI) and Coso
Transmission Line Partners (CTLP), but does not include all disclosures required
by accounting principles generally accepted in the United States of America.

(2)      New Accounting Pronouncements

The  consolidated  financial  statements  of the Coso  Partnerships  include the
accounts of CPLSI and CTLP, as a result of the adoption of Financial  Accounting
Standards  Board  (FASB)  Interpretation  No.  46.  (FIN 46)  (Consolidation  of
Variable Interest  Entities),  an interpretation of Accounting Research Bulletin
No. 51. FIN 46 required certain variable interest entities to be consolidated by
the primary  beneficiary  of the entity even though the equity  investors do not
have the  characteristics of a controlling  financial  interest,  or do not have
sufficient  equity at risk for the  entity to  finance  its  activities  without
additional  subordinated financial support from other parties. In December 2003,
the FASB issued FIN 46 (R),  which  clarified  and replaced FIN 46 that required
all  variable  interest  entities,  regardless  of when they were  created to be
evaluated  under FIN 46 (R) no later than the period  ending March 15, 2004.  An
entity shall be subject to  consolidation  according to the provisions of FIN 46
(R) if, by design,  the following  conditions  exist. As a group, the holders of
the  equity   investment   at  risk  lack  any  one  of  the   following   three
characteristics of a controlling financial interest:  (1) the direct or indirect
ability to make decisions about an entity's  activities through voting rights or
similar  rights;  (2) the obligation to absorb the expected losses of the entity
if they occur; or (3) the right to receive the expected  residual returns of the
entity if they occur.  The Coso  Partnerships  believe that CLPSI and CTLP,  the
entities that holds the inventory and transmission  assets are variable interest
entities and under FIN 46 (R) should be  consolidated.  The  inventory,  related
physical assets, and payables will be recorded as the Coso Partnership's  assets
and  liabilities.  The  impact to the Coso  Partnership's  future  statement  of
operations will be increased depreciation, partially offset by other income.

                                       32

The consolidated and combined financial statements related to prior periods have
been restated to  consolidate  the accounts of CLPSI and CTLP as a direct result
of the adoption of FIN 46 (R). There was no cumulative  effect recorded upon the
adoption of the Interpretation.

(3)      Accounts Receivable and Revenue Recognition

Accounts receivable primarily consist of receivables from Edison for electricity
delivered  and sold under a power  purchase  contract.  Operating  revenues  are
recognized  as income  during the period in which  electricity  is  delivered to
Edison.

(4)      Reclassifications

Certain  balances  in prior  years  have been  reclassified  to  conform  to the
presentation adopted in the current year.
