                          CAITHNESS COSO FUNDING CORP.
              NOTES TO THE UNAUDITED CONDENSED FINANCIAL STATEMENTS



(1)      Organization and Operations

Caithness Coso Funding Corp. (Funding Corp.) was incorporated on April 22, 1999,
in Delaware.  Funding Corp. is a special purpose corporation that was formed for
the purpose of issuing senior secured notes on behalf of Coso Finance  Partners,
Coso  Energy  Developers  and Coso  Power  Developers  (the Coso  partnerships),
affiliates  of Funding Corp.  Funding Corp.  has loaned all of the proceeds from
the offering of 6.80%  senior  secured  notes due 2001 and 9.05% senior  secured
notes due 2009 (a total of $413 million) to the Coso partnerships,  and the Coso
partnerships  have jointly and severally  guaranteed on a senior  secured basis,
repayment of the senior secured notes.

Funding  Corp.  has no  material  assets  other than the loans,  and the accrued
interest thereon,  that have been made to the Coso  partnerships.  Also, Funding
Corp. does not conduct any business, other than issuing the senior secured notes
and making the loans to the Coso partnerships.

(2)      Basis of Presentation

The accompanying  unaudited condensed financial statements have been prepared in
accordance with generally accepted  accounting  principles for interim financial
information.  Accordingly, certain information and footnote disclosures normally
included in financial  statements prepared in accordance with generally accepted
accounting  principles  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, 1999.

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
                          COMBINED FINANCIAL STATEMENTS

(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 under a 24-year power purchase contract expiring in 2011.

(2)      Basis of Presentation

The accompanying  unaudited  condensed combined  financial  statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information. Accordingly, certain information and footnote disclosures
normally included in financial  statements prepared in accordance with generally
accepted  accounting  principles 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, 1999.

On May 27, 1999 Coso Finance  Partners II was merged into Coso Finance  Partners
to form one partnership.

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)      Acquisition

On  February  25,  1999,   Caithness   Acquisition   Company,   LLC   (Caithness
Acquisition),  a wholly owned subsidiary of Caithness Energy LLC,  purchased all
of CalEnergy Company Inc.'s (CalEnergy)  interest in CFP for approximately $62.0
million.  The  acquisition was accounted for under the purchase  method,  and no
goodwill was recorded.  After  Caithness  Acquisition's  purchase of CalEnergy's
interest  in CFP, a new basis of  accounting  was  adopted and is referred to as
"New  Basis" as  compared  to the former cost basis which is referred to as "Old
Basis" in the  financial  statements.  The purchase  price was  allocated to the
portion of the assets and liabilities  purchased from CalEnergy based upon their
fair  values,  with the  amount  of fair  value of net  assets  in excess of the
purchase price being allocated to long-lived assets on a pro-rata basis.

In order to complete  the  purchase of  CalEnergy's  interest in CFP,  Caithness
Acquisition  arranged  for  short-term  debt  financing of  approximately  $77.6
million.  This  short-term debt was repaid on May 28, 1999 from a portion of the
proceeds from the offering of senior secured notes (see note 4).

(4)      Debt Financing

On May 28, 1999 Caithness Coso Funding Corp. loaned approximately $151.6 million
to CFP from a portion of the proceeds from the offering of senior secured notes.
The loan  consists  of one note of $29.0  million at 6.80% and another of $122.6
million at 9.05% with maturity dates of December 15, 2001 and December 15, 2009,
respectively.  All prior  project  loans of  approximately  $180.0  million were
repaid from the proceeds of the  financing  and an  extraordinary  loss from the
early  extinguishment of this debt was incurred for approximately  $2.4 million.
The extraordinary  loss was due to a premium and other costs incurred to pay the
prior project loans before maturity.

                             COSO ENERGY DEVELOPERS
              NOTES TO THE UNAUDITED CONDENSED FINANCIAL STATEMENTS

(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
under a 24-year power purchase contract expiring in 2019.

(2)      Basis of Presentation

The accompanying  unaudited condensed financial statements have been prepared in
accordance with generally accepted  accounting  principles for interim financial
information.  Accordingly, certain information and footnote disclosures normally
included in financial  statements prepared in accordance with generally accepted
accounting  principles  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, 1999.

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)      Acquisition

On  February  25,  1999,   Caithness   Acquisition   Company,   LLC   (Caithness
Acquisition),  a wholly owned subsidiary of Caithness Energy LLC,  purchased all
of CalEnergy Company, Inc.'s (CalEnergy) interest in CED for approximately $69.0
million.  The  acquisition was accounted for under the purchase  method,  and no
goodwill was recorded.  After  Caithness  Acquisition's  purchase of CalEnergy's
interest  in CED, a new basis of  accounting  was  adopted and is referred to as
"New  Basis" as  compared  to the former cost basis which is referred to as "Old
Basis" in the  financial  statements.  The purchase  price was  allocated to the
portion of the assets and liabilities  purchased from CalEnergy based upon their
fair  values,  with the  amount  of fair  value of net  assets  in excess of the
purchase price being allocated to long-lived assets on a pro-rata basis.

In order to complete  the  purchase of  CalEnergy's  interest in CED,  Caithness
Acquisition  arranged  for  short-term  debt  financing of  approximately  $55.2
million.  This  short-term debt was repaid on May 28, 1999 from a portion of the
proceeds from the offering of senior secured notes (see note 4).

 (4)     Debt Financing

On May 28, 1999 Caithness Coso Funding Corp. loaned approximately $107.9 million
to CED from a portion of the proceeds from the offering of senior secured notes.
The loan  consists of one note of $11.65  million at 6.80% and another of $96.25
million at 9.05% with maturity dates of December 15, 2001 and December 15, 2009,
respectively. All prior project loans of approximately $93.2 million were repaid
from the  proceeds of the  financing  and an  extraordinary  loss from the early
extinguishment  of this debt was incurred for  approximately  $1.8 million.  The
extraordinary  loss was due to a premium  and other  costs  incurred  to pay the
prior project loans before maturity.

                              COSO POWER DEVELOPERS
              NOTES TO THE UNAUDITED CONDENSED FINANCIAL STATEMENTS

(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
under a 24-year power purchase contract expiring in 2010.

(2)      Basis of Presentation

The accompanying  unaudited condensed financial statements have been prepared in
accordance with generally accepted  accounting  principles for interim financial
information.  Accordingly, certain information and footnote disclosures normally
included in financial  statements prepared in accordance with generally accepted
accounting  principles  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, 1999.

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)      Acquisition

On  February  25,  1999,   Caithness   Acquisition   Company,   LLC   (Caithness
Acquisition),  a wholly owned subsidiary of Caithness Energy LLC,  purchased all
of CalEnergy Company, Inc.'s (CalEnergy) interest in CPD for approximately $75.0
million.  The  acquisition was accounted for under the purchase  method,  and no
goodwill was recorded.  After  Caithness  Acquisition's  purchase of CalEnergy's
interest  in CPD, a new basis of  accounting  was  adopted and is referred to as
"New  Basis" as  compared  to the former cost basis which is referred to as "Old
Basis" in the  financial  statements.  The purchase  price was  allocated to the
portion of the assets and liabilities  purchased from CalEnergy based upon their
fair  values,  with the  amount  of fair  value of net  assets  in excess of the
purchase price being allocated to long-lived assets on a pro-rata basis.

In order to complete  the  purchase of  CalEnergy's  interest in CPD,  Caithness
Acquisition  arranged  for  short-term  debt  financing of  approximately  $78.6
million.  This  short-term debt was repaid on May 28, 1999 from a portion of the
proceeds from the offering of senior secured notes (see note 4).

(4)      Debt Financing

On May 28, 1999 Caithness Coso Funding Corp. loaned approximately $153.6 million
to CPD from a portion of the proceeds from the offering of senior secured notes.
The loan  consists  of one note of $69.4  million at 6.80% and  another  note of
$84.2 million at 9.05% with maturity dates of December 15, 2001 and December 15,
2009, respectively. All prior project loans of approximately $139.9 million were
repaid from the proceeds of the  financing  and an  extraordinary  loss from the
early  extinguishment of this debt was incurred for approximately  $2.1 million.
The extraordinary  loss was due to a premium and other costs incurred to pay the
prior project loans before maturity.

ITEM 2.   Management's Discussion and Analysis of Financial Condition and
          Results of Operations

         Except for  historical  financial  information  contained  herein,  the
matters  discussed in this  quarterly  report may be considered  forward-looking
statements  within the meaning of Section 27A of the  Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as amended, and
subject to the safe harbor  created by the Securities  Litigation  Reform Act of
1995.  Such  statements  include  declarations  regarding the intent,  belief or
current  expectations of Caithness Coso Funding Corp.  ("Funding  Corp."),  Coso
Finance  Partners ("the Navy I Partnership"),  Coso Energy  Developers ("the BLM
Partnership"),  and  Coso  Power  Developers  ("the  Navy II  Partnership",  and
together  with  the  Navy I  Partnership  and the  BLM  Partnership  (the  "Coso
Partnerships")  and  their  respective  management.   Any  such  forward-looking
statements  are not  guarantees  of future  performance  and involve a number of
risks and  uncertainties;  actual  results  could differ  materially  from those
indicated by such forward-looking  statements.  Among the important factors that
could cause actual  results to differ  materially  from those  indicated by such
forward-looking  statements  are: (i) that the  information  is of a preliminary
nature  and may be  subject to  further  adjustment,  (ii) risks  related to the
operation  of power  plants,  (iii) the impact of  avoided  cost  pricing,  (iv)
general  operating risks,  (v) the dependence on third parties,  (vi) changes in
government regulation,  (vii) the effects of competition,  (viii) the dependence
on  senior   management,   (ix)   fluctuations  in  quarterly  results  and  (x)
seasonality.

General

         The Coso projects consist of three 80MW geothermal power plants,  which
are referred to as Navy I, BLM and Navy II, and their transmission lines, wells,
gathering  system 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  projects.  On February 25, 1999  Caithness
Acquisition  Company,  LLC,  purchased all of CalEnergy's  interests in the Coso
projects for $205.0 million in cash,  plus $5.0 million in contingent  payments,
plus the assumption of CalEnergy's and its affiliates' share of debt outstanding
at the Coso projects which then totaled approximately $67.0 million.

         Each Coso partnership  sells 100% of the electrical energy generated at
its plant to Southern  California Edison  ("Edison") under a long-term  Standard
Offer No.4 power purchase agreement. Each Partnership's power purchase agreement
expires after the final  maturity date of the 6.8% Series B Senior Secured Notes
due 2001 and the 9.05% Series B Senior  Secured Notes due 2009 issued by Funding
Corp.

         Each Coso partnership  receives the following  payments under its power
purchase agreement:

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

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

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

                                       20

       Energy  payments  are fixed  for the first ten years of firm  operation
under each power purchase  agreement.  Firm operation was achieved for each Coso
partnership  when Edison and that Coso  partnership  agreed that each generating
unit at such Coso  partnership's  plant was a reliable  source of generation and
could  reasonably be expected to operate  continuously at its effective  rating.
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 partnership
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  the energy
itself  or buy it from  another  power  producer  rather  than  buy it from  the
relevant  Coso  partnership.  The  power  purchase  agreement  for  the  Navy  I
partnership will expire in August 2011, the power purchase agreement for the BLM
partnership  will expire March 2019,  and the power  purchase  agreement for the
Navy II  partnership  will expire in January 2010. The fixed energy price period
in  the  power  purchase  agreement  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.

         The Coso Partnerships have implemented a steam-sharing  program,  which
they established under a Coso Geothermal Exchange Agreement they entered into in
1994.  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 projects.  Under the
steam-sharing  program,  the  partnership  receiving the steam  transfer  splits
revenue earned from electricity  generated with the partnership that transferred
the steam.

         For the three months  ended March 31, 2000 (and since  January 12, 2000
for the Navy II  partnership),  Edison's  average avoided cost of energy paid to
the Navy I, the BLM and the Navy II  Partnerships  was 3.25(cent) per kWh, which
is substantially  below the fixed energy prices earned by the partnerships prior
to the  expiration of the fixed energy price periods of their  respective  power
purchase  agreements.  It is not  possible to predict the likely level of future
avoided cost of energy prices.

         The Coso Partnerships are required to make royalty payments to the Navy
and the Bureau of Land  Management.  The Navy I  partnership  pays a royalty for
Unit I through  reimbursement of electricity supplied to the Navy by Edison from
electricity  generated  at the Navy I  plant.  The  reimbursement  is based on a
pricing  formula that is included in the Navy  Contract.  For Units 2 and 3, the
Navy I partnership's  royalty expense paid to the 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. The BLM partnership pays a
10%  royalty  to the  Bureau  of Land  Management  based  on the  value of steam
produced.  The Navy II  partnership  pays a royalty to the Navy based on a fixed
percentage  of  electricity  sales to  Edison.  The  royalty  rate was  10.0% of
electricity sales through 1999, and increased to 18.0% for 2000 through 2004 and
will increase to 20.0% from 2005 through the end of the contract term.

       Coso 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  on  behalf  of  the  Coso  partnerships.  The  Coso
partnerships have jointly,  severally, and unconditionally  guaranteed repayment
of the senior secured notes.

       On May 28, 1999, Coso Funding Corp. issued $110.0 million of 6.80% senior
secured notes due in 2001 and $303.0  million of 9.05% senior  secured notes due
in 2009.  The proceeds from the notes were loaned to the Coso  partnerships  and
are payable to Coso Funding Corp from  payments of principal and interest on the
notes.  Coso  Funding  Corp.  does not conduct any other  operations  apart from
issuing the notes.

       Under the note agreement, the Coso partnerships established accounts with
a  depositary  and pledged  those  accounts  as security  for the benefit of the
holders of the senior secured notes.  All amounts  deposited with the depositary
are, at the direction of the Coso  partnerships,  invested by the  depositary 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 depositary of a certificate from the relevant Coso partnerships detailing
the amounts to be paid from funds in its respective revenue account.

                                       21

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 capacity 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:

     kWh produced (000s)                        198,906            194,718


         The Navy I partnership's  energy  production for the three months ended
March 31, 2000,  was 197.9  million kWh as compared to 129.1 million kWh for the
same period in 1999,  an increase of 53.3%.  This  increase for the three months
ended March 31, 2000,  is  attributable  to the outage of one turbine  generator
unit during that period in 1999.  The changes in energy  production for the Navy
II and BLM partnership's were insignificant over the two periods.

         Total operating  revenues for the Navy I partnership,  which consist of
capacity  payments,  capacity  bonus  payments  and energy  payments,  were $9.0
million for the three months ended March 31, 2000,  as compared to $13.2 million
for the same  period  in 1999,  a  decrease  of  31.8%.  The Navy I  partnership
capacity  and  capacity  bonus  revenues  were $1.3 million for the three months
ended March 31, 2000, as compared to $0.7 million for the  comparable  period in
1999, an increase of 85.7%.  The Navy I partnership's  energy revenues were $7.7
million for the three months ended March 31, 2000,  as compared to $12.5 million
for the same period in 1999, a decrease of 38.4%. The decreases in operating and
energy revenues for the three month period ending March 31, 2000, were primarily
due to a reduction in steam  transfers  from the Navy I  partnership  to the BLM
partnership  and  the  Navy  II  partnership  during  that  period.   These  two
partnerships  were  both  receiving  higher  fixed  energy  prices  under  their
respective  power  purchase  agreements  during the same period in 1999 and were
passing along the additional revenue to Navy I. For the three months ended March
31,  2000,  the  Navy  I  partnership   recorded  steam  transfer   revenues  of
approximately  $ 0.3 million from the BLM partnership and $ 0.9 million from the
Navy II  partnership.  Steam transfer  revenues for the three months ended March
31, 2000,  were a total of $1.2 million as compared to $8.5 million for the same
period in 1999,  a decrease of $7.3  million.  The  decrease  in steam  transfer
revenues was partially  offset by an increase in energy  revenues  excluding the
steam  transfer  payments  of $2.6  million  due to the  outage  of one  turbine
generator unit during that period in 1999 which increased  capacity and capacity
bonus revenues during that same period in 2000.

         Total operating revenues for the BLM partnership were $ 7.2 million for
the three months ended March 31, 2000, as compared to $21.4 million for the same
period in 1999, a decrease of 66.4%. The BLM partnership's  energy revenues were
$6.0 million for the three  months  ended March 31,  2000,  as compared to $20.2
million for the same  period in 1999,  a decrease  of 70.3%.  These  significant
decreases  were due to the expiration of the fixed energy price period under the
BLM  partnership's  power  purchase  agreement  in March 1999 and the receipt of
energy payments based on Edison's  avoided cost of energy since that time. Until
March 1999 the BLM  partnership  received  approximately  14.6 cents per kWh for
energy delivered.  Under the avoided cost of energy formula, the BLM partnership
has been  receiving  an average of  approximately  3.25 cents per kWh for energy
delivered.  The  decrease in revenues  due to the  reduction in energy price was
partially  offset  by a  reduction  in  steam  transfer  payments  to the Navy I
partnership of $3.2 million compared to the same period in 1999.

                                       23

         Total operating  revenues for the Navy II partnership were $9.8 million
for the three months ended March 31, 2000,  as compared to $24.6 million for the
same  period in 1999,  a decrease  of 60.2%.  The Navy II  partnership's  energy
revenues  were $8.6  million  for the three  months  ended  March 31,  2000,  as
compared to $23.4 million for the same period in 1999, a decrease of 63.2%.  The
decreases  were due to the  expiration in January 2000 of the fixed energy price
period under the Navy II partnership's  power purchase agreement and the receipt
of energy  payments  based on Edison's  avoided  cost of energy since that time.
Until January 11, 2000,  the Navy II  partnership  received  approximately  14.6
cents per kWh for energy  delivered.  Under the avoided cost of energy  formula,
the Navy II  partnership  has been  receiving an average of  approximately  3.25
cents per kWh for  energy  delivered.  Similar  decreases  are  expected  in the
upcoming quarters as the Navy II partnership  experiences the full effect of the
expiration of the fixed energy price period. The decrease in revenues due to the
reduction  in energy  price has been  partially  offset by a reduction  in steam
transfer payments to the Navy I partnership of $4.1 million compared to the same
period in 1999.

     The Navy I  partnership's  interest and other income were  $323,000 for the
three  months  ended March 31,  2000,  as compared to $1.7  million for the same
period in 1999,  a decrease of 81.0%.  The  decrease  for the three months ended
March 31, 2000, is attributable to a $1.6 million  insurance  recovery  recorded
during the first quarter of 1999 in connection  with the shut-down of one of the
Navy I  partnership's  turbine  generator  unit. The  partnership  has recovered
$500,000  with respect to the  insurance  and has reserved  the  remaining  $1.1
million pending  resolution of the insurance  claim.  The decrease was partially
offset by an increase in interest income due to a larger restricted cash balance
during the three months  ended March 31, 2000 from that of March 31,  1999.  The
BLM  partnership's  interest  and other  income was $5.3  million  for the three
months  ended March 31,  2000,  as  compared to $196,000  for the same period in
1999.  This increase of $5.1 million was primarily due to a legal  settlement of
$5  million  with  Dow  Chemical  Company  ("Dow")  paid to the BLM  partnership
combined  with a larger  restricted  cash balance  during the three months ended
March 31, 2000 from that of March 31, 1999. The Navy II  partnership's  interest
and other income was $529,000 for the three month period  ending March 31, 2000,
as compared to $306,000 for the same period in 1999,  an increase of 72.9%.  The
increase resulted from increased interest income due to a larger restricted cash
balance required by the senior secured notes during the three months ended March
31, 2000 from that of March 31, 1999.

         The Navy I partnership's  operating  expenses,  including operating and
general and  administrative  expenses,  were $2.0  million for the three  months
ended March 31, 2000, as compared to $4.6 million for the same period in 1999, a
decrease of 56.5%. The BLM partnership's operating expenses, including operating
and general and administrative  expenses, were $2.5 million for the three months
ended March 31, 2000, as compared to $5.6 million for the same period in 1999, a
decrease  of 55.4%.  The Navy II  partnership's  operating  expenses,  including
operating  and general and  administrative  expenses,  were $2.1 million for the
three  months  ended March 31,  2000,  as compared to $4.5  million for the same
period in 1999, a decrease of 53.3%.  The decreases for each of the partnerships
for the three months ended March 31, 2000, as compared to 1999,  were  primarily
due to reductions in legal  expenses as a result of a settlement  agreement with
Edison that is subject to  California  Public  Utility  Commission  approval and
reductions in operator and management  committee fees due to the  replacement of
the Coso project's  prior operator and managing  partner.  Operating  costs were
also  reduced  as  compared  to the same  period in 1999 with the  exception  of
property  tax  payments  for the  Navy I and  Navy  II  partnerships.  The  Coso
Partnerships  are currently  disputing  their property tax  assessment  with the
County of Inyo.

         The Navy I partnership's royalty expense was $1.2 million for the three
months ended March 31, 2000,  as compared to $1.4 million for the same period in
1999, a decrease of 14.3%.  This  decrease was due to  decreased  steam  sharing
revenues over the same period in 1999. The BLM partnership's royalty expense was
$65,000 for the three months  ended March 31, 2000,  as compared to $1.9 million
for the same period in 1999,  a decrease of 96.6%.  This  decrease  was due to a
reduction in BLM  partnership's  revenue  caused by the  expiration of the fixed
energy price  period under the BLM  partnership's  power  purchase  agreement in
March 1999 and the receipt of energy  payments  under  Edison's  avoided cost of
energy  since that time.  The Navy II  partnership's  royalty  expense  was $1.8
million for the three months  ended March 31, 2000,  as compared to $2.9 million
for the same period in 1999,  a decrease of 37.9%.  This  decrease  was due to a
reduction in Navy II partnership  revenues caused by the expiration of the fixed
energy price period under the Navy II partnership's  power purchase agreement in
January 2000 and the receipt of energy  payments under Edison's  avoided cost of
energy since that time partially  offset by an increase in royalty rate for that
same period in 2000.

an  increase  of 33.3%.  The Navy II  partnership's  interest  expense and other
related  costs were $2.5 million for the three  months ended March 31, 2000,  as
compared to $2.7 million for the same period in 1999, a decrease of 7.4%.  These
changes were due to the allocation of outstanding  debt balances  resulting from
the $413 million senior secured financing which closed on May 28, 1999.

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 development costs,  distributions to
partners and payments with respect to the project debt.

         The  following  table sets  forth a summary of each Coso  partnership's
cash flows for the three months ended March 31, 2000 and March 31, 1999.

</TABLE>


         The Navy I partnership's cash flows from operating activities decreased
by $633,000  for the three  months ended March 31, 2000 as compared to March 31,
1999,  primarily  due to a reduction in net income caused by a decrease in steam
transfer revenue. The decrease was partially offset by an increase in cash flows
caused by decreases in both accounts receivable and intercompany receivables.

         Cash used in investing  activities at the Navy I partnership  decreased
by $3.4  million for the three  months ended March 31, 2000 as compared to March
31, 1999,  primarily due to the use of restricted cash, for the repayment of the
project loan.

         The Navy I partnership's cash flows from financing activities decreased
by $3.6  million for the three  months ended March 31, 2000 as compared to March
31, 1999, primarily due to repayment of the project loan.

         The BLM partnership's cash flows from operating activities decreased by
$7.3  million for the three months ended March 31, 2000 as compared to March 31,
1999,  primarily due to a reduction in net income  resulting from the expiration
of the fixed  energy price period  under the BLM  partnership's  power  purchase
agreement  in March 1999 and the  receipt of energy  payments  based on Edison's
avoided cost of energy  since that time.  Cash flows from  operating  activities
also  decreased  due to  increases  in  both  accounts  receivable  and  prepaid
expenses.

         Cash used in investing  activities at the BLM partnership  decreased by
$3.1  million for the three months ended March 31, 2000 as compared to March 31,
1999,  primarily  due to the use of  restricted  cash,  for the repayment of the
project loan.

         The BLM partnership's cash flows from financing activities decreased by
$4.3  million for the three months ended March 31, 2000 as compared to March 31,
1999, primarily due to repayment of the project loan.

                                     27

         The  Navy  II  partnership's  cash  flows  from  operating   activities
decreased  by $1.5 million for the three months ended March 31, 2000 as compared
to March 31,  1999,  primarily  due to a reduction  in net income  caused by the
expiration in early January 2000 of the fixed energy price period under the Navy
II  partnership's  power purchase  agreement and the receipt of energy  payments
based on Edison's  avoided cost of energy since that time.  The decrease in cash
flows was partially offset by a decrease in accounts receivable.

         Cash  used  in  investing  activities  at  the  Navy  II  partnership's
decreased by $44.2 million for the three months ended March 31, 2000 as compared
to March 31, 1999, primarily due to the use of restricted cash for the repayment
of the project loan.

         The  Navy  II  partnership's  cash  flows  from  financing   activities
decreased by $45.3 million for the three months ended March 31, 2000 as compared
to March 31, 1999, primarily due to repayment of the project loan.

Year 2000

         In 1999, the Coso  partnership's  developed a plan to identify,  assess
and  remediate  "Year 2000"  issues  within each of their  significant  computer
programs and certain  machinery and equipment.  The Coso  partnerships  have not
experienced  disruptions to their  financial or operating  activities  caused by
failure of  computerized  systems from Year 2000 issues.  In addition,  the Coso
partnerships have not experienced disruptions to operations caused by failure of
computerized systems of suppliers or customers from Year 2000 issues. Management
of the Coso  partnerships  do not  expect  Year 2000  issues to have a  material
adverse effect on their power plant's operations or financial results in 2000.

PART II.  OTHER INFORMATION

ITEM 1.  Legal Proceedings

Settlement of Litigation

      In February  2000,  the Navy I, Navy II, and BLM  partnerships  and Edison
reached a settlement, subject to the approval of the California Public Utilities
Commission of litigation  between the Coso Partnerships and Edison as more fully
described in the 10-Q for the quarter ended  September 30, 1999. The cost of the
settlement was allocated among the Coso Partnerships. A portion of that cost was
reflected in the purchase  accounting  applied to the acquisition of CalEnergy's
interest in the partnership.

General

         Except  as  otherwise   described  above,  the  Coso  partnerships  are
currently  parties to  various  minor  items of  litigation,  none of which,  if
determined  adversely,  would be material to the financial condition and results
of operations of the Coso partnerships, either individually or taken as a whole.
