                          CAITHNESS COSO FUNDING CORP.
              NOTES TO THE UNAUDITED CONDENSED 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 of  $110,000  of 6.80%  Notes due 2001 and  $303,000 of 9.05%
Notes  due 2009 were  loaned  to the  Partnerships,  and the  Partnerships  have
jointly and severally  guaranteed  repayment on a senior  basis.  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 loans,  and the accrued
interest thereon,  that have been made to the Partnerships.  Also, Funding Corp.
does not conduct any business,  other than issuing the senior  secured notes and
making the 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,
2002.

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.

                              COSO FINANCE PARTNERS
              NOTES TO THE UNAUDITED CONDENSED FINANCIAL STATEMENTS
                             (Dollars in thousands)


(1)     Organization and Operation

Coso Finance Partners (CFP), a general partnership,  is engaged in the operation
of a 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,
2002.

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.

(3)     Accounts Receivable and Revenue Recognition

Due to the uncertainty  surrounding Edison's ability to make payment on past due
amounts,  collection  was not  reasonably  assured  and  CFP had not  recognized
revenue  from  Edison for energy  delivered  during the period  November 1, 2000
through  March 26, 2001.  On March 1, 2002,  Edison  reached  certain  financing
milestones and paid CFP for revenue generated, but not recognized for the period
November 1, 2000 through March 26, 2001. For the three-month  period ended March
31, 2002,  CFP  recognized  revenue for energy  delivered  from November 1, 2000
through March 26, 2001 of $37.3 million.

(4)     Reclassifications

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

(5)     New Accounting Pronouncements

In June 2001,  the  Financial  Accounting  Standards  Board issued  Statement of
Financial  Accounting  Standards (SFAS) No. 143, Accounting for Asset Retirement
Obligations.  This Statement  addresses  financial  accounting and reporting for
obligations associated with the retirement of tangible long-lived assets and the
associated asset  retirement costs and amends SFAS No. 19, Financial  Accounting
and Reporting by Oil and Gas Producing  Companies.  The Statement  requires that
the fair value of a liability for an asset  retirement  obligation be recognized
in the period in which it is incurred if a  reasonable  estimate of a fair value
can be made, and that the associated  asset  retirement  costs be capitalized as
part of the carrying amount of the long-lived  asset. The Statement is effective
for financial  statements issued for fiscal years beginning after June 15, 2002.

                                       11

As a result of the  adoption of SFAS No. 143,  the  Partnership  was required to
recognize  a  liability  of  $2,039,  a net  asset of $259  and a loss  from the
cumulative effect of a change in accounting principle of $1,780 as of January 1,
2003. In 2003  additional  depreciation  and accretion  expense  resulting  from
adoption of SFAS No. 143 is estimated to be $218.

                             COSO ENERGY DEVELOPERS
              NOTES TO THE UNAUDITED CONDENSED FINANCIAL STATEMENTS
                             (Dollars in thousands)


(1)     Organization and Operation

Coso Energy Developers (CED), a general partnership, is engaged in the operation
of a 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,
2002.

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

Due to the uncertainty  surrounding Edison's ability to make payment on past due
amounts,  collection  was not  reasonably  assured  and  CED had not  recognized
revenue  from  Edison for energy  delivered  during the period  November 1, 2000
through  March 26, 2001.  On March 1, 2002,  Edison  reached  certain  financing
milestones and paid CED for revenue generated, but not recognized for the period
November 1, 2000 through March 26, 2001. For the three-month  period ended March
31, 2002,  CED  recognized  revenue for energy  delivered  from November 1, 2000
through March 26, 2001 of $37.1 million.

(4)      Reclassifications

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

(5)     New Accounting Pronouncements

In June 2001,  the  Financial  Accounting  Standards  Board issued  Statement of
Financial  Accounting  Standards (SFAS) No. 143, Accounting for Asset Retirement
Obligations.  This Statement  addresses  financial  accounting and reporting for
obligations associated with the retirement of tangible long-lived assets and the
associated asset  retirement costs and amends SFAS No. 19, Financial  Accounting
and Reporting by Oil and Gas Producing  Companies.  The Statement  requires that
the fair value of a liability for an asset  retirement  obligation be recognized
in the period in which it is incurred if a reasonable estimate of a fair value

                                       16

can be made, and that the associated  asset  retirement  costs be capitalized as
part of the carrying amount of the long-lived  asset. The Statement is effective
for financial  statements issued for fiscal years beginning after June 15, 2002.
As a result of the  adoption  of SFAS No. 143 the  Partnership  was  required to
recognize  a  liability  of  $1,122,  a net  asset of $198  and a loss  from the
cumulative  effect of a change in accounting  principle of $924 as of January 1,
2003. In 2003  additional  depreciation  and accretion  expense  resulting  from
adoption of SFAS No. 143 is estimated to be $120.

                              COSO POWER DEVELOPERS
              NOTES TO THE UNAUDITED CONDENSED FINANCIAL STATEMENTS
                             (Dollars in thousands)


(1)     Organization and Operation

Coso Power Developers (CPD), a general partnership,  is engaged in the operation
of a 80 MW power generation facility located at the Coso Hot Springs, China 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
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,
2002.

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.

(3)     Accounts Receivable and Revenue Recognition

Due to the uncertainty  surrounding Edison's ability to make payment on past due
amounts,  collection  was not  reasonably  assured  and  CPD had not  recognized
revenue  from  Edison for energy  delivered  during the period  November 1, 2000
through  March 26, 2001.  On March 1, 2002,  Edison  reached  certain  financing
milestones and paid CPD for revenue  generated but not recognized for the period
November 1, 2000 through March 26, 2001. For the three-month  period ended March
31, 2002,  CPD  recognized  revenue for energy  delivered  from November 1, 2000
through March 26, 2001 of $38.0 million.

(4)     Reclassifications

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

(5)     New Accounting Pronouncements

In June 2001,  the  Financial  Accounting  Standards  Board issued  Statement of
Financial  Accounting  Standards (SFAS) No. 143, Accounting for Asset Retirement
Obligations.  This Statement  addresses  financial  accounting and reporting for
obligations associated with the retirement of tangible long-lived assets and the
associated asset  retirement costs and amends SFAS No. 19, Financial  Accounting
and Reporting by Oil and Gas Producing  Companies.  The Statement  requires that
the fair value of a liability for an asset  retirement  obligation be recognized
in the period in which it is incurred if a reasonable estimate of a fair value

                                       21

can be made, and that the associated  asset  retirement  costs be capitalized as
part of the carrying amount of the long-lived  asset. The Statement is effective
for financial  statements issued for fiscal years beginning after June 15, 2002.
As a result of the  adoption  of SFAS No. 143 the  Partnership  was  required to
recognize  a  liability  of  $2,131,  a net  asset of $354  and a loss  from the
cumulative effect of a change in accounting principle of $1,777 as of January 1,
2003. In 2003  additional  depreciation  and accretion  expense  resulting  from
adoption of SFAS No. 143 is estimated to be $334.

General

     The Coso Partnerships  consist of three 80MW geothermal power plants, which
are referred to as Navy I, BLM and Navy II, and their transmission lines, wells,
gathering  systems and other related  facilities.  The Coso projects 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. Affiliates of Caithness Corporation and
CalEnergy Company, Inc. ("CalEnergy"),  which is now known as MidAmerican Energy
Holdings  Company,  formed  the  Coso  Partnerships  in the  1980s  to  develop,
construct, own and operate the Coso Partnerships. On February 25, 1999 Caithness
Acquisition  Company,  LLC, (CAC) purchased all of CalEnergy's  interests in the
Coso Partnerships.

     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 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.

                                       23

     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 a Coso Partnership's power purchase agreement expires, Edison makes energy
payments  to the Coso  Partnerships  based on Edison's  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 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 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.  Subsequent  to the  five-year
period, 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.  Estimates of Edison's future avoided cost of energy may vary
significantly  and it is not possible to predict with  accuracy the likely level
of future avoided cost of energy prices.

     From January 1, 2002 through April 30, 2002, the Coso Partnerships  elected
to receive from Edison a fixed  energy rate of 3.25 cents per kWh.  Starting May
1, 2002,  the Coso  Partnerships  received  5.37 cents per kWh,  pursuant to the
agreement discussed above.

     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  California  Public  Utilities  Commission
(CPUC),  and is subject to future revision.  Indices utilized in the calculation
of the Navy I partnership  Unit 1 contract  energy  pricing  remained  unchanged
historically  based  on an  agreement  between  the  U.S.  Navy  and the  Navy I
partnership. In October 2002 and November 2001, modifications to the calculation
of the  reimbursement  pricing  formula  were  made to the  U.S.  Navy  Contract
resulting in a reduction of accrued  royalties of $1.3 million and $6.5 million,
respectively,  which was agreed to by the U.S.  Navy. 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 at 15% of  revenue
received by the Navy I  partnership  through 2003 and will  increase to 20% from
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 $60,000.
The BLM partnership pays a 10% royalty to the Bureau of Land Management based on
the net value of steam produced.  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 was 10% of electricity sales through 1999, and increased to 18% for
2000  through  2004 and will  increase  to 20% from 2005  through the end of the
contract term. 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.

                                       24

     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 issuing 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.

     Periodic  increases in natural gas prices and imbalances between supply and
demand,  among other  factors,  have at times led to  significant  increases  in
wholesale  electricity  prices in California.  During those periods,  Edison had
fixed  tariffs with their retail  customers  that were  significantly  below the
wholesale   prices  it  paid  in   California.   This  resulted  in  significant
under-recoveries  by Edison of its  electricity  purchase  costs. On January 16,
2001,  Edison announced that it was temporarily  suspending  payments for energy
provided,  including  the energy  provided by the Coso  Partnerships,  pending a
permanent solution to its liquidity crisis.  This cash flow shortfall  adversely
affected Edison's liquidity and in turn it did not pay the Coso Partnerships for
energy  delivered  from November 2000 through March 26, 2001. As of December 31,
2001, the Coso Partnerships were unable to determine the time frame during which
any  future  payments  would be  received.  Due to the  uncertainty  surrounding
Edison's  ability  to make  payment  on past  due  amounts,  collection  was not
reasonably  assured  and the  Navy  I,  BLM and  Navy  II  Partnerships  had not
recognized   revenue  of  $22.0  million,   $21.8  million  and  $22.7  million,
respectively, from Edison for Energy delivered during the period January 1, 2001
through March 26, 2001.

     Pursuant  to a CPUC  order,  Edison  resumed  making  payments  to the Coso
Partnerships  beginning with power generated on March 27, 2001. Edison also made
a payment equal to 10% of the unpaid  balance for power  generated from November
1, 2000 to March 26, 2001, and paid interest on the outstanding amount at 7% per
annum.  That payment was made pursuant to the Agreement  between  Edison and the
Coso  Partnerships  described  above.  On March 1, 2002,  Edison reached certain
financing  milestones  and paid  Navy I, BLM and  Navy II $37.3  million,  $37.1
million  and  $38.0  million,   respectively,  for  revenue  generated  but  not
recognized for the period November 1, 2000 through March 26, 2001.

     On  September  23, 2002,  the United  States Court of Appeals for the Ninth
Circuit issued an opinion and order on appeal from a district court's stipulated
judgment,  which affirmed the stipulated judgment in part and referred questions
based on California state law to the California Supreme Court. The appeals court
stated that if the  Agreement  violated  California  state law, then the appeals
court would be required to void the stipulated judgment.  The California Supreme
Court has accepted  the Ninth  Circuit  Court of Appeals  request to address the
issues referred to it in the September 23, 2002 ruling.  Pending the findings of
the  California  Supreme  Court on matters  relating to state law, the Agreement
remains in full force and effect.

     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. The Coso Partnerships'  Agreements set a 1.0 line
loss factor 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, if
Edison's challenge to the CPUC ruling stands.


                                       25

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


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:

     Total energy  production  for the Navy I Partnership  was 173.7 million kWh
for the three-months  ended March 31, 2003, as compared to 184.2 million kWh for
the same period in 2002,  a decrease of 5.7%.  Total energy  production  for the
Navy II Partnership was 169.8 million kWh for the  three-months  ended March 31,
2003,  as compared to 188.4  million kWh for the same period in 2002, a decrease
of  9.9%.  The  decrease  in  energy  production  for  the  Navy I and  Navy  II
Partnerships  was  primarily  due to a  decline  in steam  which  management  is
attempting to remediate through well maintenance and capital  improvements.  The
decline in total energy  production for the BLM  Partnership was not significant
for the period  March 31, 2003 as compared  to March 31,  2002.  In an effort to
increase  production,  the Coso  Partnerships have implemented a capital program
including  drilling two new productions wells and performing  workovers on three
existing  wells  to  regain   production   currently  limited  due  to  wellbore
obstructions.  The Coso Partnerships expect to enhance the steam utilization and
efficiency of the projects  through a turbine  enhancement and  modifications to
wellfield  piping and gas removal  systems.  With respect to the  reservoir,  an
injection  augmentation  program,  aimed at  improving  reservoir  pressure  and
minimizing resource decline, is currently in the engineering design phase.

     Total  operating  revenues  for the Navy I,  BLM and Navy II  Partnerships,
which consist of capacity  payments,  capacity bonus payments,  energy payments,
were  $12.6  million,  $9.3  million  and $8.5  million,  respectively,  for the
three-months  ended March 31, 2003, as compared to $45.5 million,  $43.5 million
and of $44.4 million,  respectively,  for the same period in 2002,  decreases of
$32.9  million,  $34.2  million and $35.9  million,  respectively.  Capacity and
capacity  bonus  revenues  for each of the Navy I, BLM and Navy II  Partnerships
were  $1.3  million,  $1.2  million  and  $1.2  million,  respectively,  for the
three-months  ended March 31, 2003,  as compared to $3.1 million for each of the
Partnerships  for the same  period  in 2002,  decreases  of $1.8  million,  $1.9
million and $1.9 million respectively. Total energy revenues for the Navy I, BLM
and Navy II  Partnerships  were $11.3  million,  $8.1 million and $7.3  million,
respectively,  for the  three-months  ended March 31, 2003, as compared to $42.4
million, $40.4 million and of $41.4 million,  respectively,  for the same period
in  2002,   decreases  of  $31.1  million  $32.3  million  and  $34.1   million,
respectively.  Each of the Coso Partnerships'  decreases in operating  revenues,
capacity and capacity  bonus revenues and energy  revenues for the  three-months
ended March 31, 2003, as compared to the same period in 2002, were primarily due
to the recognition of revenues  generated but not recognized for the period from
November 1, 2000 through March 26, 2001 discussed  above.  On March 1, 2002, the
Navy I, BLM and Navy II Partnerships  received payment and recognized revenue of
$37.3 million,  $37.1 million and $38.0 million,  respectively.  These decreases
were  partially  offset by an increase in the fixed rate of energy to 5.37 cents
per kWh paid  during the  three-months  ended March 31, 2003 as compared to 3.25
cents per kWh for the same period in 2002, also discussed above.

     The Navy II  Partnership's  operating  expenses,  including  operating  and
general and  administrative  expenses,  were $2.4  million for the  three-months
ended March 31, 2003 as compared to $2.0 million for the same period in 2002, an
increase of 20.0%.  The increase for the  three-months  ended March 31, 2003, as
compared to the same period in 2002 was  primarily  due to  increased  insurance
costs and property  tax.  The Navy I and BLM  Partnerships  operating  expenses,
including operating and general and administrative expenses for the three-months
ended March 31,  2003 as  compared to the same period in 2002 had  insignificant
changes over the two periods.  The increased  insurance costs and property taxes
for the Navy I and BLM Partnerships  for the three-month  period ended March 31,
2003  were  insignificant,  due to  increased  drilling  and  maintenance  costs
incurred during the same period in 2002.

     The  Navy I  Partnership's  royalty  expenses  were  $2.7  million  for the
three-months  ended March 31,  2003,  as  compared to $2.2  million for the same
period in 2002, an increase of 22.7%.  The BLM  Partnership's  royalty  expenses
were $25,000 for the  three-months  ended March 31, 2003, as compared to $11,000
for the same period in 2002, an increase of $14,000.  The Navy II  Partnership's
royalty expenses were $1.5 million for the three-months ended March 31, 2003, as
compared  to $1.1  million  for the same  period in 2002,  an increase of 36.4%.
These  increases in royalty expense for the Navy I, BLM and Navy II Partnerships
for the  three-months  ended  March 31,  2003 as  compared to the same period in
2002,  were due to an increase in the fixed rate of energy to 5.37 cents per kWh
for the three-month  period ended March 31, 2003 from 3.25 cents per kWh for the
three-month period ended March 31, 2002 discussed above.

decrease of 26.3%. These decreases in depreciation and amortization  expense for
the  three-months  ended  March 31, 2003 as compared to the same period in 2002,
were due to older wells being fully depreciated during the second half of 2002.

     Interest and other income for the Navy I, BLM and Navy II Partnerships were
$59,000,  $282,000 and $79,000,  respectively,  for the three-months ended March
31, 2003, as compared to $474,000, $642,000 and $482,000,  respectively, for the

These  decreases for the  three-months  ended March 31, 2003, as compared to the
same period in 2002, were primarily due to interest on amounts in arrears,  owed
by Edison in 2001, that were settled and paid by Edison on March 1, 2002.

     The  Navy I  Partnership's  interest  expense  was  $2.5  million  for  the
three-months  ended March 31,  2003,  as  compared to $2.8  million for the same
period in 2002, a decrease of 10.7%. The BLM Partnership's  interest expense was
$2.0  million for the  three-months  ended March 31,  2003,  as compared to $2.2
million  for  the  same  period  in  2002,  a  decrease  of  9.1%.  The  Navy II
Partnership's interest expense was $1.8 million for the three-months ended March
31, 2003, as compared to $1.9 million for the same period in 2002, a decrease of
5.3%. These decreases in interest  expense for the three-months  ended March 31,
2003,  as  compared  to the same  period in 2002 were due to  reductions  in the
principal amount of the project loan from Funding Corp.

                                       29
Change in Accounting Principle

     The Navy I, BLM and Navy II Partnerships  recorded a loss on the cumulative
effect of change in accounting  principle in the amounts of $1.8  million,  $0.9
million and $1.8  million,  respectively  for the  three-months  ended March 31,
2003. This loss was due to adoption of SFAS No. 143 as described in the notes to
the financial statements.


Liquidity and Capital Resources

     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.  As of
December  2001,  the 6.8%  notes  were  repaid,  subsequently  leaving  the Coso
Partnerships with more cash flow annually. 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 debt.

     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 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.  Pending a response from the California Supreme
Court, the Agreement  remains in full force and effect.  Immediately  after this
Edison-CPUC settlement, Edison and each of the Coso Partnerships entered into an
amendment of their respective Agreement (referenced above) pertaining to partial
payment and interest  payments relating to Edison's past due obligations for the
period from November 1, 2000 through March 26, 2001. The Agreement,  as amended,
was approved by the 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  Funding  Corp.
notes.

     On March 1, 2002, Edison reached certain financing  milestones and paid the
Coso  Partnerships for revenue  generated but not recognized for the period from
November 1, 2000 through March 26, 2001. In the first quarter of 2002,  the Navy
I, BLM and Navy II Partnerships  recognized  revenue for energy delivered during
that period of $37.3 million, $37.1 million and $38.0 million, respectively.


     The following  table sets forth a summary of each Coso  Partnership's  cash
flows for the three-months ended March 31, 2003 and March 31, 2002.

recognized for the period November 1, 2000 through March 26, 2001 and a decrease
in amounts due from related parties.

     Cash used in investing  activities at the Navy I  Partnership  decreased by
$0.4 million for the three-months  ended March 31, 2003, as compared to the same

Edison's  payment  received  on March  1,  2002 for  revenue  generated  but not
recognized  for the period  November 1, 2000  through  March 26, 2001  partially
offset by a decrease in trade payables.

     Cash  used  in  investing   activities  at  the  BLM  Partnership  for  the
three-months  ended  March 31,  2003,  as  compared  to the same  period in 2002
decreased by an insignificant amount over the two periods.

     The BLM Partnership's cash used in financing  activities decreased by $22.8
million  for the  three-months  ended  March 31,  2003,  as compared to the same
period in 2002, due to decreased partner  distributions  paid during that period

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


(1)     Basis of Presentation

The accompanying  unaudited condensed combined financial statements were derived
from the stand alone unaudited condensed financial  statements of Caithness Coso
Funding  Corp.,  Coso Finance  Partners,  Coso Energy  Developers and Coso Power
Developers ("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  condensed
combined financial statements should be read in conjunction with each individual
Partnership's unaudited condensed financial statements.

(2)     Accounts Receivable and Revenue Recognition

Due to the uncertainty  surrounding Edison's ability to make payment on past due
amounts, collection was not reasonably assured and the Coso Partnerships had not
recognized  revenue from Edison for energy  delivered during the period November
1, 2000  through  March 26,  2001.  On March 1,  2002,  Edison  reached  certain
financing  milestones and paid the Coso Partnerships for revenue generated,  but
not recognized  for the period  November 1, 2000 through March 26, 2001. For the
three-month  period  ended  March 31,  2002,  the Coso  Partnerships  recognized
revenue for energy  delivered  from  November 1, 2000 through  March 26, 2001 of
$112.4 million.

(3)     Reclassifications

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

(4)     New Accounting Pronouncements

In June 2001,  the  Financial  Accounting  Standards  Board issued  Statement of
Financial  Accounting  Standards (SFAS) No. 143, Accounting for Asset Retirement
Obligations.  This Statement  addresses  financial  accounting and reporting for
obligations associated with the retirement of tangible long-lived assets and the
associated asset  retirement costs and amends SFAS No. 19, Financial  Accounting
and Reporting by Oil and Gas Producing  Companies.  The Statement  requires that
the fair value of a liability for an asset  retirement  obligation be recognized
in the period in which it is incurred if a  reasonable  estimate of a fair value
can be made, and that the associated  asset  retirement  costs be capitalized as
part of the carrying amount of the long-lived  asset. The Statement is effective
for financial  statements issued for fiscal years beginning after June 15, 2002.
As a result of the  adoption  of SFAS No. 143 the  Partnership  was  required to
recognize  a  liability  of  $5,292,  a net  asset  of  $811  and a loss  from a
cumulative effect of a change in accounting principle of $4,481 as of January 1,
2003. In 2003 an additional  depreciation and accretion  expense  resulting from
adoption of SFAS No. 143 is estimated to be $675.
