PART I/ITEM 1.    FINANCIAL STATEMENTS

         The unaudited condensed financial statements contained herein have been
prepared pursuant to the rules and regulations of the United States Securities
and Exchange Commission (the "Commission"). Certain information and footnote
disclosures normally included in annual financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted. While the management of LS Power Funding Corporation ("Funding"),
LSP-Cottage Grove, L.P. ("Cottage Grove") and LSP-Whitewater Limited Partnership
("Whitewater"), (Cottage Grove and Whitewater sometimes referred to herein
individually as a "Partnership" and collectively as the "Partnerships") believes
that the disclosures made are adequate to make the information presented not
misleading, these unaudited condensed financial statements should be read in
conjunction with the audited financial statements included in the Annual Report
on Form 10-K for the year ended December 31, 1999, filed by Funding, and the
Partnerships.


PART I/ITEM 2.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                  AND RESULTS OF OPERATIONS

         In addition to discussing and analyzing Funding and the Partnerships'
recent historical financial results and condition, the following "Management's
Discussion and Analysis of Financial Condition and Results of Operations"
includes statements concerning certain trends and other forward-looking
information affecting or relating to Funding and the Partnerships which are
intended to qualify for the protections afforded "Forward-Looking Statements"
under the Private Securities Litigation Reform Act of 1995, Public Law 104-67.
The forward-looking statements made herein are inherently subject to risks and
uncertainties which could cause Funding's and the Partnerships' actual results
to differ materially from the forward-looking statements.

GENERAL

         Cottage Grove is a single purpose Delaware limited partnership
established in December 1993 to develop, finance, construct and own a gas-fired
cogeneration facility located in Cottage Grove, Minnesota (the "Cottage Grove
Facility"). The 1% general partner, LSP-Cottage Grove, Inc., and the 72% limited
partner, Cogentrix Cottage Grove, LLC, are indirect subsidiaries of Cogentrix
Energy, Inc. ("Cogentrix Energy"). The other limited partner is TPC Cottage
Grove, Inc. ("TPC Cottage Grove") and is not affiliated with Cogentrix Energy.
Whitewater is a single purpose Delaware limited partnership established in
December 1993 to develop, finance, construct and own a gas-fired cogeneration
facility located in Whitewater, Wisconsin (the "Whitewater Facility", and
collectively with the Cottage Grove Facility, the "Facilities"). The 1% general
partner, LSP-Whitewater I, Inc., and the 73% limited partner, Cogentrix
Whitewater, LLC, are indirect subsidiaries of Cogentrix Energy. The other
limited partner is TPC Whitewater ("TPC Whitewater"), an affiliate of TPC
Cottage Grove that is not affiliated with Cogentrix Energy. The Partnerships
sell electric capacity and energy generated by their Facilities to two utilities
under separate long-term power purchase agreements (individually, the "Power
Purchase Agreement" and collectively, the "Power Purchase Agreements").
Whitewater sells up to 236.5 megawatts of electric capacity and associated
energy generated by the Whitewater Facility to Wisconsin Electric Power Company
("WEPCO") pursuant to a 25-year Power Purchase Agreement. Whitewater may also
sell to third parties up to 12 megawatts of electric capacity and any energy not
dispatched by WEPCO. All of the electric capacity and energy generated by the
Cottage Grove Facility is sold to Northern States Power Company ("NSP") pursuant
to a 30-year Power Purchase Agreement. The Partnerships also have long-term
steam supply agreements with steam hosts to supply thermal energy produced by
the Facilities.

         The Whitewater Facility commenced commercial operations on September
18, 1997, and the Cottage Grove Facility commenced commercial operations on
October 1, 1997. The Whitewater and Cottage Grove Power Purchase Agreements meet
the criteria of a "sales-type" capital lease as described in Statement of
Financial Accounting Standards ("SFAS") No. 13, "Accounting for Leases." Cottage
Grove and Whitewater each recognized a gain on sales-type capital lease for the
difference between the estimated fair market value and the historical cost of
the Facilities as of the commencement of each respective Power Purchase
Agreement's terms (commencement of commercial operations). The Partnerships each
recorded a net investment in lease that reflects the present value of future
minimum lease payments. Future minimum lease payments represent the amount of
capacity payments due from the utilities under the Power Purchase Agreements in
excess of fixed operating costs (i.e., executory costs).



                                       3
<PAGE>   4
The difference between the undiscounted future minimum lease payments due from
the utilities and the net investment in lease represents unearned income. This
unearned income will be recognized as lease revenue over the respective terms of
the Power Purchase Agreements using the effective interest rate method. The
Partnerships will also recognize service revenue related to the reimbursement of
costs incurred in operating the Facilities and providing electricity and thermal
energy. The amount of service revenue recognized by each Partnership will be
directly related to the level of dispatch of the Facilities by the respective
utilities and to a lesser extent the level of thermal energy required by the
steam hosts.

Funding

         Funding was organized in June 1995 as a special purpose Delaware
corporation to issue debt securities in connection with financing the
construction of the Facilities. Funding's sole business activities are limited
to maintaining its organization and activities necessary pursuant to the
offering of the Senior Secured Bonds (defined below) and its acquisition of the
First Mortgage Bonds (defined below) from the Partnerships.

         The Senior Secured Bonds are the following:

                  7.19% Senior Secured Bonds Due 2010, Series A of LS Power
                  Funding Corporation
                  8.08% Senior Secured Bonds Due 2016, Series A of LS Power
                  Funding Corporation

         The First Mortgage Bonds are the following:

                  7.19% First Mortgage Bonds of LSP-Cottage Grove, L.P. Due 2010
                  8.08% First Mortgage Bonds of LSP-Cottage Grove, L.P. Due 2016
                  7.19% First Mortgage Bonds of LSP-Whitewater Limited
                  Partnership Due 2010
                  8.08% First Mortgage Bonds of LSP-Whitewater Limited
                  Partnership Due 2016

         Cottage Grove and Whitewater each own 50% of the outstanding stock of
Funding.

RESULTS OF OPERATIONS

Cottage Grove

         Operating revenues increased approximately 9.1% for the first quarter
of 2000 as compared to the first quarter of 1999. This increase was primarily a
result of an increase in service revenue and commodity sales. The increase in
service revenue resulted from an increase in the variable energy rate charged to
the purchasing utility as a result of an increase in natural gas prices. The
increase in service revenue was partially offset by a decrease in megawatt hours
provided to the purchasing utility. The increase in commodity sales resulted
primarily from an increase in remarketed fuel sales to third party purchasers.

         Operating expenses increased approximately 18.4% for the first quarter
of 2000 as compared to the first quarter of 1999. This increase was the result
of increases in cost of services and commodity sales expense. The increase in
cost of services resulted from an increase in fuel expense, a component of cost
of services, as a result of an increase in natural gas prices. The increase in
fuel expense was partially offset by a decrease in other operating expenses
as a result of a decrease in megawatt hours provided to the purchasing utility.
Commodity sales expense increased due to an increase in remarketed fuel sales to
third party purchasers.

         Interest expense consists primarily of interest expense on the First
Mortgage Bonds and amortization of the costs incurred to issue the bonds.

Whitewater

         Operating revenues increased approximately 16.6% for the first quarter
of 2000 as compared to the first quarter of 1999. This increase was primarily
the result of an increase in service revenue and commodity sales. The increase
in service revenue resulted from an increase in the variable energy rate charged
to the purchasing utility as a result of an increase in natural gas prices,
which was partially offset by a decrease in megawatt hours provided to the



                                       4
<PAGE>   5

purchasing utility. Commodity sales expense increased due to an increase in
remarketed fuel sales to third party purchasers.

         Operating expenses increased approximately 32.3% for the first quarter
of 2000 as compared to the first quarter of 1999. This increase was primarily
the result of increases in cost of services and commodity sales expense. The
increase in cost of services resulted from an increase in fuel expense, a
component of cost of services, as a result of an increase in natural gas prices,
which was partially offset by decreased megawatt hours sold to the purchasing
utility. Commodity sales expense increased due to an increase in remarketed fuel
sales to third party purchasers.

         Interest expense consists primarily of interest expense on the First
Mortgage Bonds and amortization of the costs incurred to issue the bonds.

OPERATIONS AND MAINTENANCE

Operations and Maintenance Agreements

         Each of the Cottage Grove and Whitewater Facilities is operated by its
respective general partner pursuant to operations and maintenance agreements (an
"O&M Agreement", and collectively, the "O&M Agreements") expiring in 2004. Under
each O&M Agreement, the general partners are required to provide certain
services during the operation of the Facilities. As compensation for its
services, each general partner is reimbursed under each O&M Agreement on a
monthly basis for certain approved costs incurred in connection with operating
the related Facility. In addition, each general partner will receive an annual
management fee of $350,000 (subject to adjustment each year based on specified
indices). The Partnerships contract directly with certain subcontractors for
materials and services which are outside the scope of the general partners'
obligations under the O&M Agreements, including major maintenance of the
Facilities. The general partners are also subject to an annual performance bonus
or penalty depending upon each Facility's availability relative to certain
performance criteria reflecting aspects of similar criteria contained in each
Facility's Power Purchase Agreement. Furthermore, the general partners are
subject to a penalty payment depending upon each Facility's ability to produce
an uninterrupted supply of thermal energy.

LIQUIDITY AND CAPITAL RESOURCES

Cottage Grove

         The principal components of operating cash flow for the three-month
period ending March 31, 2000 were net income of $1.9 million, a $0.1 million
adjustment for amortization of debt issuance and financing costs and a net $4.9
million of cash provided by changes in other working capital assets and
liabilities, which were partially offset by amortization of unearned lease
income, net of minimum lease payments received of $0.1 million. Cash flow
provided by operating activities of $6.8 million was primarily used to fund $6.4
million of restricted cash.

Whitewater

         The principal components of operating cash flow for the three-month
period ended March 31, 2000 were net income of $2.1 million, a $0.2 million
adjustment for depreciation and amortization of debt issuance and financing
costs, a net $4.3 million of cash provided by changes in other working capital
assets and liabilities and amortization of unearned lease income, net of minimum
lease payments received of $0.1 million. Cash flow provided by operating
activities of $6.7 million and a portion of the cash on hand at the beginning of
the period of $0.1 million was primarily used to fund $6.8 million of restricted
cash.

         The $332,000,000 of proceeds received by Funding from the sale of the
Senior Secured Bonds were used by Funding to acquire (i) $155,000,000 of Cottage
Grove First Mortgage Bonds and (ii) $177,000,000 of Whitewater First Mortgage
Bonds. In addition to the proceeds of the First Mortgage Bonds, the Partnerships
each received equity contributions from TPC Cottage Grove and TPC Whitewater in
1997, in the respective amounts of $18,167,000 for Cottage Grove and $20,556,000
for Whitewater (the "Equity Contribution Amounts"). The net proceeds from the
sale of the Partnerships' First Mortgage Bonds and the Equity Contribution
Amounts together with other sources of funds available to the Partnerships were
used to: (i) finance the development, design,



                                       5
<PAGE>   6
engineering, construction, testing, inspection and start-up of the Facilities,
(ii) pay interest on the Partnerships' First Mortgage Bonds during construction
and (iii) maintain a debt service reserve fund as required by certain financing
documents. During 1999 and 1998, the Partnerships transferred the cash held in
their debt service reserve funds to Cogentrix Energy. The funds, currently equal
to $6,585,000 and $7,519,000 for Cottage Grove and Whitewater, respectively, are
included on the respective balance sheets as a Note Receivable from Affiliate.
The receivables are backed by an irrevocable letter of credit issued on behalf
of a subsidiary of Cogentrix Energy.

         In addition to funds received through the acquisition of the First
Mortgage Bonds by Funding and through the Equity Contribution Amounts, each
Partnership may each receive on its behalf certain letters of credit to be
issued pursuant to a letter of credit facility which expires in June 2002. Each
letter of credit facility provides for letters of credit in a face amount not to
exceed $5,000,000 for Whitewater and $5,500,000 for Cottage Grove, which may be
drawn on by the respective Partnership from time to time. Such letters of credit
will satisfy certain requirements of the Partnerships under various project
agreements. Cottage Grove has issued a $500,000 letter of credit under the
Cottage Grove letter of credit facility to secure certain obligations of Cottage
Grove under the Cottage Grove Power Purchase Agreement.

         In order to provide for the Partnerships' working capital needs, the
Partnerships have each entered into a working capital facility. Each working
capital facility will provide for working capital loans in an aggregate
principal amount not to exceed $3,000,000 for each Partnership. At March 31,
2000, no amounts were outstanding under the working capital facilities.

         The Partnerships expect that payments from the utilities under the
Power Purchase Agreements will provide the substantial majority of their
revenues. Under and subject to the terms of the Power Purchase Agreements, each
utility is obligated to purchase electric capacity made available to it and
energy that it requests from the related Partnership. For additional information
regarding NSP and WEPCO, reference is made to the respective Annual Reports
filed on Form 10-K, the Quarterly Reports filed on Form 10-Q, proxy, and any
other filings made by NSP and WEPCO with the Commission.

         The Power Purchase Agreements are dispatchable contracts that provide
the utilities the right to suspend or reduce purchases of electricity from the
Facilities. The Power Purchase Agreements are structured such that the
Partnerships will continue to receive capacity payments during any period of
dispatch. Each Partnership is dependent on capacity payments under its Power
Purchase Agreement to meet its fixed obligations, including the payment of debt
service under each Partnership's First Mortgage Bonds (which will be Funding's
sole source of revenues for payment of debt service under the Senior Secured
Bonds). Capacity payments by each of NSP and WEPCO are based on the tested
capacity and availability of the Facilities and are unaffected by levels of
dispatch. Each Facility's capacity is subject to semi-annual verification
through testing. Capacity payments are subject to reduction if a Facility is
operating at reduced or degraded capacity at the time of such test, although
each Facility is permitted a retest subject to certain retest limitations. Also,
capacity payments for each Facility are subject to rebate or reduction if the
respective Facility does not maintain certain minimum levels of availability.
Under the Cottage Grove Power Purchase Agreement, capacity payments are further
adjusted by, among other things, the capacity loss factor which is determined in
accordance with procedures jointly agreed to by Cottage Grove and NSP. The
Partnerships expect to achieve the minimum capacity and availability levels;
however, any material shortfall in tested capacity or availability over a
significant period could result in a shortage of funds to the Partnerships.

         Each Partnership presently believes that funds available from cash and
investments on hand, restricted funds, operations and letter of credit and
working capital facilities will be more than sufficient to liquidate each
Partnership's obligations as they come due, pay project debt service and make
required contributions to project reserve accounts.

         As with any power generation facility, operation of the Facilities will
involve certain risks, including the performance of a Facility below expected
levels of output or efficiency, interruptions in fuel supply, pipeline
disruptions, disruptions in the supply of thermal or electrical energy, power
shut-downs due to the breakdown or failure of equipment or processes, violation
of permit requirements (whether through operation, or change in law), operator
error, labor disputes or catastrophic events such as fires, earthquakes,
explosions, floods or other similar occurrences affecting a Facility or its
power purchasers, thermal energy purchasers, fuel suppliers or fuel
transporters. The occurrence of any of these events could significantly reduce
or eliminate revenues generated by a



                                       6
<PAGE>   7

Facility or significantly increase the expenses of that Facility, thereby
impacting the ability of a Partnership to make payments of the amounts necessary
to fund principal of and interest on its First Mortgage Bonds, and,
consequently, Funding's ability to make payments of principal of and interest on
the Senior Secured Bonds. Not all risks are insured and the proceeds of such
insurance applicable to covered risks may not be adequate to cover a Facility's
lost revenues or increased expenses. In addition, extended unavailability under
the Power Purchase Agreements, which may result from one or more of such events,
may entitle the respective power purchaser to terminate its Power Purchase
Agreement.


IMPACT OF ENERGY PRICE CHANGES, INTEREST RATES AND INFLATION

         The Partnerships have attempted to mitigate the risk of increases in
fuel and transportation costs by providing contractually for matching increases
in the energy payments the Partnerships receive from the utilities purchasing
electricity generated by the Facilities. In addition, the Partnerships have
hedged against the risk of fluctuations in interest rates by arranging
fixed-rate financing.

                          LS POWER FUNDING CORPORATION
                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                                    UNAUDITED


1.       FINANCIAL STATEMENTS

     The balance sheet as of March 31, 2000 and the statements of income and
cash flows for the three-month periods ended March 31, 2000 and 1999 have been
prepared by LS Power Funding Corporation ("Funding"), without audit. In the
opinion of management, these unaudited condensed financial statements include
all adjustments (consisting of normal recurring adjustments) necessary to
present fairly Funding's financial position as of March 31, 2000, and the
results of its operations and its cash flows for the three-month periods ended
March 31, 2000 and 1999.

     The unaudited condensed financial statements have been prepared pursuant to
the rules and regulations of the United States Securities and Exchange
Commission. Certain information and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted. While management believes that the
disclosures made are adequate to make the information presented not misleading,
these unaudited condensed financial statements should be read in conjunction
with Funding's audited financial statements included in Funding's Annual Report
on Form 10-K for the fiscal year ended December 31, 1999.

2.       ORGANIZATION

     Funding was established on June 23, 1995 as a special purpose Delaware
corporation to issue debt securities in connection with financing construction
of two gas-fired cogeneration facilities, one located in Cottage Grove,
Minnesota and the other located in Whitewater, Wisconsin. LSP-Cottage Grove,
L.P. ("Cottage Grove") and LSP-Whitewater Limited Partnership ("Whitewater") are
single purpose Delaware limited partnerships established to develop, finance,
construct and own the facilities at Cottage Grove and Whitewater, respectively.
Cottage Grove and Whitewater each owns 50% of the outstanding stock of Funding.
Funding's sole business activities are limited to maintaining its organization,
the offering of the Senior Secured Bonds and its acquisition of the First
Mortgage Bonds issued by Cottage Grove and Whitewater.

3.       RECLASSIFICATION

     Certain reclassifications have been made to the prior year's financial
statements to conform with the classification used in the financial statements
as of March 31, 2000, and for the three-months ended March 31, 2000.

                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                                    UNAUDITED


1.       FINANCIAL STATEMENTS

         The balance sheet as of March 31, 2000 and the statements of income and
cash flows for the three-month periods ended March 31, 2000 and 1999 have been
prepared by LSP-Cottage Grove, L.P. (the "Partnership"), without audit. In the
opinion of management, these unaudited condensed financial statements include
all adjustments (consisting of normal recurring adjustments) necessary to
present fairly the Partnership's financial position as of March 31, 2000, and
the results of its operations and its cash flows for the three-month periods
ended March 31, 2000 and 1999.

         The unaudited condensed financial statements have been prepared
pursuant to the rules and regulations of the United States Securities and
Exchange Commission. Certain information and footnote disclosures normally
included in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted. While management believes
that the disclosures made are adequate to make the information presented not
misleading, these unaudited condensed financial statements should be read in
conjunction with the Partnership's audited financial statements included in the
Partnership's Annual Report on Form 10-K for the Fiscal Year ended December 31,
1999.


2.       ORGANIZATION

         The Partnership is a Delaware limited partnership that was formed on
December 14, 1993 to develop, finance, construct and own a gas-fired
cogeneration facility with a design capacity of approximately 245 megawatts
located in Cottage Grove, Minnesota (the "Facility"). Construction and start-up
of the Facility was substantially completed and commercial operation commenced
October 1, 1997 (the "Commercial Operations Date"). The 1% general partner of
the Partnership is LSP-Cottage Grove, Inc., ("Cottage Grove"), a wholly-owned
subsidiary of Cogentrix Cottage Grove, LLC, ("Cogentrix Cottage Grove").
Cogentrix Cottage Grove and TPC Cottage Grove, Inc., are the sole limited
partners of the Partnership, owning approximately 72% and 27% limited
partnership interests, respectively. The ultimate parent of Cogentrix Cottage
Grove is Cogentrix Energy, Inc. ("Cogentrix Energy"), a North Carolina
corporation.

         The Partnership holds a 50% equity ownership interest in LS Power
Funding Corporation ("Funding"), which was established on June 23, 1995 as a
special purpose funding corporation to issue debt securities (the "Senior
Secured Bonds") in connection with financing construction of the Facility and a
similar gas-fired cogeneration facility located in Whitewater, Wisconsin. On
June 30, 1995, a portion of the proceeds from the offering and sale of the
Senior Secured Bonds issued by Funding was used to purchase $155 million of
First Mortgage Bonds issued simultaneously by the Partnership.

         All of the electric capacity and energy generated by the Facility is
sold to Northern States Power Company, (the "Utility") under a 30-year power
purchase agreement (the "Power Purchase Agreement"). The thermal energy
generated by the Facility is sold in the form of steam to Minnesota Mining and
Manufacturing Company (the "Steam Purchaser") under a 30-year thermal energy
sales agreement.


3.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

CASH AND CASH EQUIVALENTS

         For purposes of reporting cash flows, cash equivalents include
unrestricted short-term investments with original maturities of three months or
less.


                                      F-9
<PAGE>   19


RESTRICTED CASH

         The majority of the revenue received by the Partnership is required to
be deposited into accounts administered by the trustee under the trust indenture
for the First Mortgage Bonds (the "Trustee"). The Trustee invests funds held in
these accounts at the direction of the Partnership. The funds are invested in
commercial paper, high grade government money market funds and overnight
repurchase obligations secured by U.S. Treasury Notes. The investments are
carried at cost, which approximates market at March 31, 2000 and December 31,
1999. In addition, special accounts are established to provide for debt service
reserves and payments, and major maintenance reserves. Amounts held by the
Trustee in accounts designated for debt service and major maintenance, which
might otherwise be considered cash equivalents, are treated as restricted cash.

POWER PURCHASE AGREEMENT

         All of the electric capacity and energy generated by the Facility is
sold to the Utility under the Power Purchase Agreement. The Power Purchase
Agreement has characteristics similar to a lease in that the agreement confers
to the Utility the right to use specific property, plant and equipment. At the
Commercial Operations Date, the Partnership accounted for the Power Purchase
Agreement as a "sales-type" capital lease in accordance with Statement of
Financial Accounting Standards ("SFAS") No. 13, "Accounting for Leases" (see
Note 4).

NOTE RECEIVABLE FROM AFFILIATE

         At March 31, 2000, the Partnership had a note receivable from Cogentrix
Energy. This amount represents funds required to be on account for debt service.
The note receivable is backed by a letter of credit issued to the Partnership.
The note receivable bears interest at the three-month LIBOR rate plus 0.25%, and
is due December 15, 2016.

LEASE REVENUE

         Lease revenue represents the amortization of unearned income on the
lease using the effective interest rate method as well as contingent rentals
that result from changes in payment escalators occurring subsequent to the
Commercial Operations Date. These contingent rentals are not expected to
materially change the lease revenue recognized over the life of the Power
Purchase Agreement.

SERVICE REVENUE

         Service revenue represents reimbursement to the Partnership of costs
incurred to operate the Facility and to provide variable electric energy to the
Utility and thermal energy to the Steam Purchaser.

COMMODITY SALES

         Commodity sales consist primarily of commodity sales of excess natural
gas fuel inventory, including amounts remarketed directly to third parties.

COST OF SERVICES

         Cost of services represents expenses related to operating the Facility
and providing variable electric energy to the Utility as well as thermal energy
to the Steam Purchaser.

INCOME TAXES

         Under current tax laws, income or loss of partnerships is included in
the income tax returns of the partners. Accordingly, the Partnership makes no
provision for federal and state income taxes. The tax returns of the Partnership
are subject to examination by federal and state taxing authorities. If such
examinations occur and result in changes with respect to the Partnership
qualification, or in changes in distributable partnership income or loss, the
tax liability of the partners would be changed accordingly.

USE OF ESTIMATES

         The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

RECLASSIFICATION

         Certain reclassifications have been made to the prior period's
financial statements to conform with the classification used in the financial
statements as of March 31, 2000, and for the three-months then ended.


4.       SALES-TYPE CAPITAL LEASE

         Upon the Commercial Operations Date of the Facility, the Partnership
recognized a gain on sales-type capital lease of $87.1 million reflecting the
difference between the estimated fair market value ($233.6 million) and the
historical cost ($146.5 million) of the Facility. The interest rate implicit in
the lease is 9.01%. The estimated residual value of the Facility at the end of
the lease term is $0. The components of the net investment in lease at March 31,
2000, are as follows (dollars in thousands):

                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                                    UNAUDITED


1.       FINANCIAL STATEMENTS

         The balance sheet as of March 31, 2000 and the statements of income and
cash flows for the three-month periods ended March 31, 2000 and 1999 have been
prepared by LSP-Whitewater Limited Partnership (the "Partnership"), without
audit. In the opinion of management, these unaudited condensed financial
statements include all adjustments (consisting of normal recurring adjustments)
necessary to present fairly the Partnership's financial position as of March 31,
2000 and the results of its operations and its cash flows for the three-month
periods ended March 31, 2000 and 1999.

         The unaudited condensed financial statements have been prepared
pursuant to the rules and regulations of the United States Securities and
Exchange Commission. Certain information and footnote disclosures normally
included in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted. While management believes
that the disclosures made are adequate to make the information presented not
misleading, these unaudited condensed financial statements should be read in
conjunction with the Partnership's audited financial statements included in the
Partnership's Annual Report on Form 10-K for the Fiscal Year ended December 31,
1999.


2.       ORGANIZATION

         LSP-Whitewater Limited Partnership is a Delaware limited partnership
that was formed on December 14, 1993 to develop, finance, construct and own a
gas-fired cogeneration facility with a design capacity of approximately 245
megawatts located in Whitewater, Wisconsin (the "Facility"). Construction and
start-up of the Facility was substantially completed and commercial operation
commenced September 18, 1997 (the "Commercial Operations Date"). The 1% general
partner of the Partnership is LSP-Whitewater I, Inc., a wholly-owned subsidiary
of Cogentrix Whitewater, LLC ("Cogentrix Whitewater"). Cogentrix Whitewater and
TPC Whitewater, Inc. are the sole limited partners of the Partnership, owning
approximately 73% and 26% limited partnership interests, respectively. The
ultimate parent of Cogentrix Whitewater is Cogentrix Energy, Inc. ("Cogentrix
Energy"), a North Carolina corporation.

         The Partnership holds a 50% equity ownership interest in LS Power
Funding Corporation ("Funding"), which was established on June 23, 1995 as a
special purpose Delaware corporation to issue debt securities (the "Senior
Secured Bonds") in connection with financing construction of the Facility and a
similar gas-fired cogeneration facility located in Cottage Grove, Minnesota. On
June 30, 1995, a portion of the proceeds from the offering and sale of the
Senior Secured Bonds issued by Funding was used to purchase $177 million of
First Mortgage Bonds issued simultaneously by the Partnership.

         The Partnership sells up to 236.5 megawatts of electric capacity and
associated energy generated by the Facility to Wisconsin Electric Power Company
("WEPCO" or, as the context requires, the "Utility") pursuant to a 25-year power
purchase agreement (the "Power Purchase Agreement"). The Partnership may also
sell to third parties up to 12 megawatts of electric capacity and any energy
that is not dispatched by WEPCO. The thermal energy generated by the Facility is
provided in the form of steam to the University of Wisconsin - Whitewater under
a steam supply agreement expiring on June 30, 2005 and in the form of hot water
to a greenhouse owned by the Partnership (collectively, the "Steam Purchasers").


3.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

CASH AND CASH EQUIVALENTS

         For purposes of reporting cash flows, cash equivalents include
unrestricted short-term investments with original maturities of three months or
less.

RESTRICTED CASH

         The majority of the revenue received by the Partnership is required to
be deposited into accounts administered by the trustee under the trust indenture
for the First Mortgage Bonds (the "Trustee"). The Trustee invests funds held in
these accounts at the direction of the Partnership. The funds are invested in
commercial paper, high grade government money market funds and overnight
repurchase obligations secured by U.S. Treasury Notes. The investments are
carried at cost, which approximates market at March 31, 2000 and December 31,
1999. In addition, special accounts are established to provide for debt service
reserves and payments, and major maintenance reserves. Amounts held by the
Trustee in accounts designated for debt service and major maintenance, which
might otherwise be considered cash equivalents, are treated as restricted cash.

POWER PURCHASE AGREEMENT

         The Partnership sells up to 236.5 megawatts of electric capacity and
associated energy generated by the Facility to the Utility pursuant to the Power
Purchase Agreement. The Power Purchase Agreement has characteristics similar to
a lease in that the agreement confers to the Utility the right to use specific
property, plant and equipment. At the Commercial Operations Date, the
Partnership accounted for the Power Purchase Agreement as a "sales-type" capital
lease in accordance with Statement of Financial Accounting Standards ("SFAS")
No. 13, "Accounting for Leases" (see Note 4).

NOTE RECEIVABLE FROM AFFILIATE

         At March 31, 2000, the Partnership had a note receivable from Cogentrix
Energy. This amount represents funds required to be on account for debt service.
The note receivable is backed by a letter of credit issued to the Partnership.
The note receivable bears interest at the three-month LIBOR rate plus 0.25%, and
is due December 15, 2016.

GREENHOUSE FACILITY

         Depreciation on the greenhouse facility and related equipment is
computed using the straight-line method over 25 years and 10 years,
respectively.

LEASE REVENUE

         Lease revenue represents the amortization of unearned income on lease
using the effective interest rate method as well as contingent rentals that
result from changes in payment escalators occurring subsequent to the Commercial
Operations Date. These contingent rentals are not expected to materially change
the lease revenue recognized over the life of the Power Purchase Agreement.

SERVICE REVENUE

         Service revenues represent reimbursement to the Partnership of costs
incurred to operate the Facility and to provide variable electric energy to the
Utility and thermal energy to the Steam Purchaser.

COMMODITY SALES

         Commodity sales consist primarily of sales of excess natural gas fuel
inventory, including amounts remarketed directly to third parties and related
parties.

COST OF SERVICES

         Cost of services represents expenses related to operating the Facility
and providing variable electric energy to the Utility as well as thermal energy
to the Steam Purchaser.

INCOME TAXES

         Under current tax laws, income or loss of partnerships is included in
the income tax returns of the partners. Accordingly, the Partnership makes no
provision for federal and state income taxes. The tax returns of the Partnership
are subject to examination by federal and state taxing authorities. If such
examinations occur and result in changes with respect to the Partnership
qualification, or in changes in distributable partnership income or loss, the
tax liability of the partners would be changed accordingly.

USE OF ESTIMATES

         The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

RECLASSIFICATION

         Certain reclassifications have been made to the prior period financial
statements to conform with the classification used in the financial statements
as of March 31, 2000 and for the three-months then ended.


4.       SALES-TYPE CAPITAL LEASE

         Upon the Commercial Operations Date of the Facility, the Partnership
recognized a gain on sales-type capital lease of $97.0 million reflecting the
difference between the estimated fair market value ($261.7 million) and the
historical cost ($164.7 million) of the Facility. The interest rate implicit in
the lease is 9.79%. The estimated residual value of the Facility at the end of
the lease term is $0. The components of the net investment in lease at March 31,
2000 are as follows (dollars in thousands):

                Gross Investment in Lease        $    564,147
                Unearned Income on Lease             (300,752)
                                                 ------------
                Net Investment in Lease          $    263,395
                                                 ============

         Gross investment in lease represents total capacity payments receivable
over the term of the Power Purchase Agreement, net of executory costs, which are
considered minimum lease payments in accordance with SFAS No. 13.
