                               EXPLANATORY NOTE

   This quarterly report includes financial statements which have not been
reviewed by an independent public accountant under Rule 10-01(d) of Regulation
S-X. We expect that our independent public accountant, PricewaterhouseCoopers
LLP, will complete the quarterly review required by Rule 10-01(d) of Regulation
S-X following their re-audit of our historical financial statements for the
three-year period ended December 31, 2001. The comparative financial
information contained in this report has been revised to reflect the known
effects of the restatement items described in Note 1 to the accompanying
Condensed Consolidated Financial Statements. Also, concurrent with the filing
of this quarterly report, Dynegy has filed a Current Report on Form 8-K that
includes revised financial statements for each of the years in the three-year
period ended December 31, 2001. These revised financial statements have been
prepared by management and reflect all known restatement items to Dynegy's
2001, 2000 and 1999 financial statements originally filed with its Annual
Report on Form 10-K for the year ended December 31, 2001. However, as a result
of the three-year re-audit and PricewaterhouseCoopers' subsequent review of
Dynegy's 2002 quarterly financial statements, it is possible that additional
adjustments to the unaudited revised financial statements in the Form 8-K and
Dynegy's 2002 quarterly reports may result, some of which could be material.
Dynegy expects to file an amended Form 10-K reflecting the unaudited
restatements described in the Form 8-K as soon as practicable after the date of
this report. Following completion of the re-audit, which the Company expects
will occur early in the first quarter 2003, further amendment of the Form 10-K
will be necessary in order to include the audit report of
PricewaterhouseCoopers LLP as well as to reflect other changes resulting from
the re-audit, if any.

             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

           For the Interim Periods Ended September 30, 2002 and 2001

Note 1--Restatements

   This Quarterly Report on Form 10-Q of Dynegy Holdings Inc. ("Dynegy" or the
"Company") gives effect to the unaudited restatements of the Company's
consolidated financial statements as of December 31, 2001 and for the three-
and nine-month periods ended September 30, 2002 and 2001, respectively.
Concurrent with the filing of this Form 10-Q, Dynegy has filed a Current Report
on Form 8-K that includes unaudited restated financial statements for each of
the three years in the period ended December 31, 2001. The restatements herein
and therein relate to the Project Alpha structured natural gas transaction, a
balance sheet reconciliation project relating principally to the Company's
natural gas marketing business and adjustments relating to a change in the
accounting for certain contracts from hedge accounting to mark-to-market
accounting under Statement of Financial Accounting Standards No. 133,
"Accounting for Derivative Instruments and Hedging Activities," as amended
("Statement No. 133"). Specifically, the restatements are as follows:

   Project Alpha.  Dynegy entered into the Project Alpha structured natural gas
transaction in April 2001. As described in a Current Report on Form 8-K dated
April 25, 2002 (the "Alpha Form 8-K"), Dynegy decided to present the cash flow
associated with the related gas supply contract as a financing activity in its
Consolidated Statements of Cash Flows for 2001. The effect of this decision was
to reclassify approximately $180 million of previously disclosed operating cash
flow to financing cash flow for the nine-month period ended September 30, 2001.
Following the disclosure in the Alpha Form 8-K and in connection with a further
review of Project Alpha, Arthur Andersen ("Andersen") informed the Company that
it could no longer support its tax opinion relating to the transaction.
Andersen's change in position was based in part on its conclusion that the
reclassification of cash flow from operations to cash flow from financing
lessened the factual basis for the opinion. Dynegy's financial statement
recognition of the tax benefit in 2001 was based principally on the Company's
assessment of the relevant issues, as corroborated by Andersen's tax opinion.
After the withdrawal of Andersen's tax opinion, management concluded that
sufficient support to include the income tax benefit for financial statement
presentation purposes no longer existed, the effect of which was a reversal of
the annual tax benefit previously recognized by the Company during the 2001
period. This decision resulted in the reversal of $36 million and $63 million,
respectively, of tax benefit previously reported for the three- and nine-month
periods ended September 30, 2001. Dynegy subsequently concluded that its
restated consolidated financial statements should include the consolidation of
ABG Gas Supply, LLC ("ABG"), one of the entities formed in connection with the
transaction. The consolidation of ABG is included herein based on compilations
of financial information received from an agent of ABG's equity holders. Such
compilations have not been audited and may change upon further assessment by
Dynegy. The most significant impact of consolidating ABG is to increase
Dynegy's consolidated indebtedness by approximately $280 million and $270
million at December 31, 2001 and September 30, 2002, respectively.

   Balance Sheet Reconciliation Project.  Dynegy originally reported an
after-tax charge of approximately $80 million ($124 million pre-tax) in the
second quarter 2002 related to a balance sheet reconciliation project
undertaken by the Company at the beginning of 2002. The charge related
principally to the Company's natural gas marketing business. The original $80
million charge has been excluded from net income for the nine-months ended
September 30, 2002. The table below reflects the impact on net income of the
re-allocation of the $80 million charge from the second quarter 2002 back to
the periods in which the transactions giving rise to the charge originally
occurred (in millions).

   Changes in Accounting Classification Under Statement No. 133.  The Company
adopted Statement No. 133 effective January 1, 2001 and reflected certain
contracts as cash flow hedges upon such adoption. Management has subsequently
determined that following the initial adoption of Statement No. 133, the
documentation of compliance requirements under the standard, particularly as it
relates to the periodic assessment of effectiveness, was inadequate to support
the accounting method previously applied. The resulting restatement reflects
the accounting for these contracts on a mark-to-market basis rather than on the
deferred basis previously employed beginning in the first quarter 2001. The
impact of the change in accounting method for these contracts increased
previously reported net income for the three-month period ended September 30,
2001 by $1 million and reduced previously reported net income from the
nine-month period ended September 30, 2001 by $21 million. The impact of the
change in accounting method for these contracts reduced reported net income for
the nine-month period ended September 30, 2002 by $3 million. The change in
accounting method employed had no impact on previously reported cash flows from
operations in any period.

       NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

           For the Interim Periods Ended September 30, 2002 and 2001


Note 2--Accounting Policies

   The accompanying unaudited condensed consolidated financial statements have
been prepared in accordance with the instructions to interim financial
reporting as prescribed by the SEC, except that they have not been reviewed by
an independent public accountant under Rule 10-01(d) of Regulation S-X. These
interim financial statements should be read in conjunction with the unaudited
restated consolidated financial statements and notes thereto included in the
Company's Current Report on Form 8-K dated November 19, 2002, which includes
unaudited restated financial statements for 1999-2001 reflecting the known
revisions described in Note 1 above (the "Restatement Form 8-K").

   The financial statements contained in this quarterly report include all
material adjustments that, in the opinion of management, are necessary for a
fair presentation of the results for the interim periods. Interim period
results are not necessarily indicative of the results for the full year. The
preparation of the condensed consolidated financial statements in conformity
with generally accepted accounting principles requires management to develop
estimates and make assumptions that affect reported financial position and
results of operations and that impact the nature and extent of disclosure, if
any, of contingent assets and liabilities. The Company reviews significant
estimates affecting its consolidated financial statements on a recurring basis
and records the effect of any necessary adjustments prior to their publication.
Judgments and estimates are based on the Company's beliefs and assumptions
derived from information available at the time such judgments and estimates are
made. Adjustments made with respect to the use of these estimates often relate
to information not previously available. Uncertainties with respect to such
estimates and assumptions are inherent in the preparation of financial
statements. Estimates are primarily used in (1) developing fair value
assumptions, including estimates of future cash flows and discount rates, (2)
analyzing tangible and intangible assets for impairment and (3) determining the
amounts to accrue related to contingencies. Actual results could differ
materially from any such estimates. Certain reclassifications have been made to
prior period amounts in order to conform to current year presentation.

   Change in Accounting Principle. EITF Issue 98-10.  In October 2002, the
Emerging Issues Task Force ("EITF" or "Task Force") reached a consensus to
rescind EITF Issue 98-10, "Accounting for Contracts Involved in Energy Trading
and Risk Management Activities" ("EITF Issue 98-10"). As such, all new energy
trading contracts entered into after October 25, 2002 that do not qualify as
derivatives under Statement No. 133 will not be accounted for using mark to
market accounting. All derivative contracts will continue to be accounted for
in accordance with Statement No. 133. With the rescission of this standard,
Dynegy will no longer record trading inventories at fair market value. The
effective date for the full rescission of EITF Issue 98-10 will be January 1,
2003. The effect of the recission of EITF Issue 98-10 will be reported as the
cumulative effect of a change in accounting principle at the time of adoption;
however, the impact is not currently known.

   Accounting Principles Adopted. EITF Issue 02-3.  In June 2002, the Task
Force reached consensus on two of three issues presented in EITF Issue 02-3,
"Accounting for Contracts Involved in Energy Trading and Risk Management
Activities" ("EITF Issue 02-3"). First, the Task Force concluded that all
mark-to-market gains and losses on energy trading contracts (whether realized
or unrealized) should be shown net in the income statement, irrespective of
whether the contract is physically or financially settled. Beginning in the
third quarter 2002, Dynegy is presenting all mark-to-market gains and losses on
a net basis to reflect this change in accounting principle. In accordance with
the transition provisions in the consensus, comparative period financial
statements have been conformed to reflect this change in accounting principle.
Dynegy has historically classified net unrealized gains and losses from energy
trading contracts as revenue in its consolidated statement of operations.
Transactions that were realized and settled were previously reflected gross in
revenues and cost of sales. This

income, earnings per share or cash flow from operations.

   The second consensus reached by the Task Force in June 2002 related to
required disclosures regarding energy trading operations. However, in October
2002, the Task Force rescinded its earlier consensus. With the rescission of
EITF Issue 98-10, as discussed above, the additional disclosures previously
called for under EITF Issue 02-3 are no longer applicable.

   The third issue addressed by the Task Force in EITF Issue 02-3 deals with
the recognition of unrealized gains and losses at inception of an energy
trading contract (commonly referred to as dealer profit). The Task Force did
not reach a consensus on this issue in October 2002.

   Finally, it is unclear whether the scope of future activities will include a
comprehensive conclusion regarding the appropriateness of the use of models as
a fundamental method for valuing transactions when market quotations are
unavailable. Should the Task Force issue definitive guidance on one or more of
these issues, such guidance may impact Dynegy. However, the extent of the
financial impact to Dynegy, if any, cannot be predicted with any degree of
certainty until the scope of the Task Force's conclusion is known and the
transition alternative is determined. If the Task Force prefers a retroactive
or a cumulative effect transition alternative, then Dynegy's historical
financial position and results of operations will be impacted negatively. If
the Task Force prefers a prospective transition alternative, then Dynegy's
current financial position will be unaffected and the impact to future
operations is not expected to be material as a result of the Company's decision
to exit third party risk management aspects of the marketing and trading
business. Please see Note 4 for further discussion.

   FASB Statement No. 142.  In July 2001, the FASB issued Statement of
Financial Accounting Standards No. 142, "Goodwill and Other Intangible Assets"
("Statement No. 142"). Statement No. 142 discontinued goodwill amortization
over its estimated useful life and provided that goodwill is subject to at
least an annual fair-value based impairment test. The Company adopted Statement
No. 142 effective January 1, 2002. The estimation of fair value is highly
subjective, inherently imprecise and can change materially from period to

period based on, among other things, an assessment of market conditions,
projected cash flows and discount rate. Accordingly, if conditions change in
the future, the Company may record further impairment losses. On an annual
basis, absent any impairment indicators, the Company expects to perform its
annual impairment analysis in the fourth quarter after the annual budgetary
process. The changes in the carrying amount of goodwill for each of Dynegy's

   FASB Statement No. 144.  In August 2001, the FASB issued Statement of
Financial Accounting Standards No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets" ("Statement No. 144"). Statement No. 144
addresses the accounting and reporting for the impairment or disposal of
long-lived assets and supersedes FASB Statement No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of"
and APB Opinion No. 30, "Reporting the Results of Operations--Reporting the
Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and
Infrequently Occurring Events and Transactions." The Company's adoption of
Statement No. 144 on January 1, 2002 did not have any impact on its financial
position, results of operations or cash flows. However, see Note 4 below
regarding the Company's treatment of assets held for sale at September 30, 2002.

   Accounting Principles Not Yet Adopted. FASB Statement No. 143.  Also during
2001, the FASB issued Statement of Financial Accounting Standards No. 143,
"Accounting for Asset Retirement Obligations" ("Statement No. 143"). Statement
No. 143 requires that the fair value of a liability for an asset retirement
obligation be recognized in the period in which it is incurred with the
associated asset retirement costs being capitalized as a part of the carrying
amount of the long-lived asset. The Company is evaluating the future financial
effects of adopting Statement No. 143 and will adopt the standard effective
January 1, 2003.

   FASB Statement No. 146.  In July 2002, the FASB issued Statement of
Financial Accounting Standards No. 146, "Accounting for Exit or Disposal
Activities" ("Statement No. 146"). Statement No. 146 addresses issues regarding
the recognition, measurement and reporting of costs that are associated with
exit and disposal activities, including restructuring activities that are
currently accounted for pursuant to the guidance that the EITF has set forth in
EITF Issue No. 94-3, "Liability Recognition for Certain Employee Termination
Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred
in a Restructuring)." The scope of Statement No. 146 also includes (1) costs
related to terminating a contract that is not a capital lease and
(2) termination benefits that employees who are involuntarily terminated
receive under the terms of a one-time benefit arrangement that is not an
ongoing benefit arrangement or an individual deferred compensation contract.
Statement No. 146 will be effective for exit or disposal activities that are
initiated after December 31, 2002, although early adoption of the standard is
encouraged. The Company is evaluating the impact of this standard on its
current restructuring initiative and will apply provisions of the standard
accordingly.

Note 3--Liquidity and Industry Conditions

   Dynegy believes its current liquidity position should be sufficient to
permit the Company to meet its debt maturities and other obligations through
the first quarter 2003. The sufficiency of the Company's liquidity will depend
upon:

  .   Dynegy's continued compliance with the covenants in its bank credit and
      other debt instruments or its ability to negotiate waivers in the event
      of a covenant default;

  .   Dynegy's ability to repay or refinance its credit facilities that mature
      in the second quarter 2003;

  .   Dynegy's ability to manage its exit from third party risk management
      aspects of the marketing and trading business and the timing of the
      expected cash flows and reduction in collateral from this exit;

  .   the level of earnings and cash flow from Dynegy's assets and businesses,
      which is subject to the effect of changes in commodity prices,
      particularly natural gas and power;

  .   Dynegy's non-investment grade credit ratings, the effect of these ratings
      on Dynegy's ability to access capital markets and to conduct normal
      commercial operations and the effect of any further downgrade in these
      credit ratings on refinancings;

  .   ongoing investigations and litigation relating to Project Alpha, Dynegy's
      trading practices and its activities in the California power markets; and

  .   confidence in Dynegy's financial reporting in light of the previously
      announced restatements and the ongoing re-audit of its 1999-2001
      financial statements.

   Dynegy's liquidity may be significantly adversely affected if it is unable
to refinance the credit facilities that mature in the second quarter 2003.
Dynegy also faces the risk of a covenant default on these facilities or other
debt instruments prior to maturity. The credit facilities contain various
covenants, including EBITDA-to-interest and debt-to-capitalization financial
covenants. The Company was in compliance with the covenants in its credit

facilities and other debt instruments at September 30, 2002. While many of the
charges incurred by the Company during 2002 are excluded from the compliance
calculations, continued weakness in the Company's operating results compared
with results in 2001 will make it more difficult for the Company to continue to
comply with certain of its financial covenants. Compliance with these financial
covenants is measured on a quarterly basis.

   Any failure to satisfy one or more of these financial covenants would
constitute a breach giving rise to a default under the applicable debt
instrument and would permit the lenders under such debt instrument to
accelerate the maturity of Dynegy's outstanding obligations thereunder.
Depending upon the particular debt instrument, such a breach or any action by
the lenders to accelerate the maturity of amounts owing would result in a
default under or trigger cross-acceleration provisions in a significant portion
of the Company's other outstanding debt instruments. In the event of
non-compliance, Dynegy would seek waivers from the lenders under these debt
instruments or attempt to repay or refinance the affected debt instruments. The
Company cannot provide any assurance that it could repay, obtain waivers with
respect to or refinance such debt instruments in the event of any such default.
   Dynegy has executed on the principal elements of its capital plan in order
to meet its current obligations as they mature and provide the necessary
collateral to support its commercial operations. Dynegy believes that the
combination of its liquidity initiatives and the roll off of collateral and
cash flow from its exit from third party risk management aspects of the
marketing and trading business should enable the Company to refinance all or a
sufficient portion of its second quarter 2003 maturities. However, the Company
faces significant risks related to its ongoing operations and other matters
discussed above. Dynegy also faces the risk that it may not be able to reach
agreement with its lenders on mutually acceptable terms. If Dynegy fails to
execute the remaining elements of its strategy, it may be forced to consider
other strategic alternatives including a possible reorganization under the
protection of federal bankruptcy laws.


   The accompanying unaudited condensed consolidated financial statements have
been prepared assuming that the Company will continue as a going concern. This
basis of accounting contemplates the recovery of the Company's assets and the
satisfaction of its liabilities in the normal course of conducting business,
which in turn is subject to the risks and contingencies discussed above.
Management believes that actions presently being taken relative to the
Company's capital plan, its revolving credit facilities and other strategic
alternatives should enable the Company to meet its obligations in a manner
consistent with this accounting treatment.

Note 4--Acquisitions and Dispositions

   Northern Natural Gas. In November 2001, Dynegy Inc., Dynegy's parent,
acquired 1,000 shares of Series A Preferred Stock ("Series A Preferred Stock")
in Northern Natural for $1.5 billion. The Company concurrently acquired an
option to purchase all of the equity of Northern Natural's indirect parent
company. The Company exercised its option to acquire the indirect parent of
Northern Natural in November 2001 upon termination of Dynegy Inc.'s merger
agreement with Enron Corp. ("Enron"), and the closing of the option exercise
occurred on January 31, 2002.

       NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

           For the Interim Periods Ended September 30, 2002 and 2001


   On August 16, 2002, Dynegy Inc. and the Company sold all of their investment
in the preferred stock and the common stock, respectively, of Northern Natural
to MidAmerican for $928 million in cash, subject to adjustment for changes in
working capital. Pursuant to the sales agreement, 95 percent of the purchase
price was allocated to the preferred stock held by Dynegy Inc. and five percent
of the purchase price was allocated to the common stock held by the Company.
Under the terms of this agreement, MidAmerican acquired all of the common and
preferred stock of Northern Natural and assumed all of Northern Natural's $950
million of debt, which debt had a book value of approximately $890 million. The
Company incurred a pre-tax loss of $62 million ($60 million after-tax)
associated with the sale. Subject to resolution of the working capital
adjustments relating to the sale, Dynegy could incur an additional loss in the
fourth quarter 2002.

   On September 30, 2002, the Company sold $90 million in 6.875 percent senior
notes of Northern Natural due May 2005 for approximately $96 million in cash.
The Company had acquired the notes at par value in April 2002 pursuant to a
tender offer that it agreed to effect in order to obtain a bondholder consent
in connection with the acquisition of Northern Natural. The gain on sale of
approximately $4 million is reflected in Other Income and is net of accrued
interest.

   As a result of the disposition during the quarter, Northern Natural is
reported as a discontinued operation in the accompanying financial statements
and these notes. Revenues from Northern Natural were $30 million and $201
million, respectively, for the three- and nine-month periods ended September
30, 2002. Income before taxes was zero and $38 million for the three- and
nine-month periods ended September 30, 2002.

   Marketing & Trading.  In October 2002, the Company announced it would exit
third party risk management aspects of the marketing and trading business. The
decision to exit this business is expected to reduce significantly the
Company's collateral requirements and overall corporate expenses. The Company
expects to complete a significant portion of this exit over the next three to
six months. During this period and thereafter, the Company will maintain the
resources and make the necessary arrangements to meet its customer commitments,
including retaining personnel and risk management capabilities. This decision
to exit third party risk management aspects of the marketing and trading
business will not change the commercial activities of Dynegy's midstream or
generation businesses. The midstream business will continue to manage commodity
price risk associated with its operations related to fuel procurement and to
market natural gas and natural gas liquids. Further, the generation business
will continue to manage commodity price risk existing in its physical asset
positions through optimizing fuel procurement and to market power from these
assets.

   Canadian Gas Marketing.  On October 17, 2002, Dynegy entered into a letter
of intent to sell a portion of its Canadian natural gas marketing business to
The Seminole Group Inc. The sale is expected to close in November 2002, subject
to regulatory approvals and other customary closing conditions. Any loss on the
sale is expected to be less than $10 million and will be recorded upon
consummation of the sale. The remaining Canadian business will consist
primarily of existing power marketing positions and physical gas in storage.

   United Kingdom Storage.  On September 30, 2002, the Company sold a
subsidiary that owned the Hornsea onshore natural gas storage facility in the
United Kingdom for net cash proceeds of approximately $189 million. No gain or
loss was recognized on the transaction. On November 14, 2002, the Company sold
the subsidiaries that owned the Rough offshore natural gas field in the North
Sea and the Easington natural gas processing terminal on the East Yorkshire
coast for cash proceeds of approximately $500 million. The Company does not
expect to recognize a material gain or loss on this transaction. The results of
operations for the United Kingdom storage business are included within
discontinued operations in the accompanying Condensed Consolidated Statements
of Operations. Revenues from the United Kingdom storage business were $47
million and $128

Note 5--Restructuring and Impairment Charges

   During the six-months ended June 30, 2002, the Company recognized a $70
million pre-tax ($46 million after-tax) charge principally related to the
impairment, write-off or obsolescence of certain assets and an accrual for
severance related to a corporate restructuring. The charge primarily relates to
the impairment of investments in securities of entities engaged in
technology-related ventures and a severance charge related to the corporate
restructuring.

   During the third quarter 2002, the Company recognized a $1,121 million
pre-tax ($1,028 million after-tax) charge principally related to the impairment
of goodwill associated with the Company's Wholesale Energy Network ("WEN")
segment, the recognition of a liquidity reserve relating to the Company's
marketing and trading portfolio, an impairment of investments in generating
facilities, a loss on the sale of Northern Natural and the write-off of other
obsolete assets.

</TABLE>

   Impairment of goodwill.  The value of goodwill associated with the WEN
segment was reviewed for impairment at September 30, 2002. Based on this
assessment, a pre-tax charge to earnings of $737 million was recorded to impair
substantially all of the goodwill associated with the WEN segment. There was no
tax basis in this intangible asset resulting in an after-tax charge equal to
the pre-tax amount. The fair value of WEN consists of value associated with
marketing and trading as well as the value associated with power generation.
The fair values of the respective components were estimated utilizing the
expected discounted future cash flows. The primary factors leading to this
impairment are: (1) the reduction in near-term power prices, (2) an increase in
the rate of return required for investors to enter the energy merchant sector
and (3) the Company's decision to exit third party risk management aspects of
the marketing and trading business. The charge was recorded in Goodwill
Impairment in the accompanying Condensed Consolidated Statement of Operations.

   Liquidity reserve.  The Company recognized a pre-tax charge of $223 million
($145 million after-tax) associated with its recognition of a liquidity reserve
in the third quarter 2002 that impairs the mark-to-market value of the
Company's marketing and trading portfolio at September 30, 2002. The
recognition of an incremental liquidity reserve in determining estimated fair
value reflects a substantial reduction during the quarter in market transaction
volumes, principally in the U.S. power marketing and trading business, and
recognizes the negative estimated impact on the realizability of the net asset
value of the portfolio. This charge is included in Revenues in the accompanying
Condensed Consolidated Statement of Operations.

   Impairment of generation investments.  In conjunction with its review of the
carrying value of goodwill, the Company assessed the carrying value of its
generation portfolio on an asset-by-asset basis. The generation portfolio
includes wholly owned generating facilities, which are reflected in Property,
Plant and Equipment, as well as investments in partnerships and limited
liability companies that own generating facilities, which are reflected in
Unconsolidated Investments. Based on this review, the carrying value associated
with the wholly owned generation facilities was considered realizable. However,
certain investments were considered impaired, resulting in a pre-tax charge of
$62 million, which is reflected in Earnings (Losses) from Unconsolidated
Investments in the accompanying Condensed Consolidated Statement of Operations.
This diminution in the fair value of these investments is a result of depressed
energy prices and an increase in the rate of return required by investors to
enter into the power generating business.

   Loss on Sale of Northern Natural.  On August 16, 2002, Dynegy Inc. and the
Company sold all of their investment in the preferred stock and the common
stock, respectively, of Northern Natural to MidAmerican for $928 million in
cash, subject to adjustment for changes in working capital. MidAmerican
acquired all of the common and preferred stock of Northern Natural and assumed
all of Northern Natural's $950 million of debt,

       NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

           For the Interim Periods Ended September 30, 2002 and 2001

which debt had a book value of approximately $890 million. Pursuant to the
sales agreement, 95 percent of the purchase price was allocated to the
preferred stock held by Dynegy Inc. and five percent of the purchase price was
allocated to the common stock held by the Company. The Company incurred a
pre-tax loss of $62 million ($60 million after-tax) associated with the sale.
This charge is recorded in Discontinued Operations in the accompanying
Condensed Consolidated Statement of Operations.

   For federal income tax purposes, the sale resulted in a capital loss, which
may be deducted solely against capital gains, if any, realized by the
enterprise in its consolidated federal tax returns. There is a five-year
carryforward for capital losses under existing federal statutes. For financial
reporting purposes, the Company recorded a valuation allowance against
substantially all of the potential tax benefit as a result of uncertainty of
realization.

   Impairment of technology investments.  The Company has investments that
include ownership in public and private companies and investment funds focused
in the technology sector. The continued downturn in the technology sector
during the second quarter 2002 resulted in an impairment charge relative to
these investments. In the second quarter 2002, the Company recorded a $26
million pre-tax ($17 million after-tax) charge.

   These investments were reevaluated at September 30, 2002 based on the
Company's inability to sell certain investments for their adjusted carrying
values and the continued depressed conditions in the technology sector. Based
on this assessment, the remaining carrying values of such investments were
written off, resulting in a pre-tax charge of $8 million ($5 million
after-tax). The cumulative pre-tax charge related to technology investments for
the nine months ended September 30, 2002 was $34 million ($22 million
after-tax) and is included in Earnings (Losses) From Unconsolidated Investments
in the accompanying Condensed Consolidated Statements of Operations.

   Severance charge.  The Company recognized a pre-tax charge of approximately
$32 million ($21 million after-tax) in the second quarter 2002 for severance
benefits for approximately 309 employees who were from various segments and
included all staffing levels, including the Company's former Chief Executive
Officer and Chief Financial Officer. $28 million ($18 million after-tax) of the
charge is included in Impairment and Other Charges in the accompanying
Condensed Consolidated Statements of Operations. The additional severance
charge of $4 million ($3 million after-tax) was allocated to Northern Natural,
which is included in Discontinued Operations in the accompanying Condensed
Consolidated Statement of Operations. The following is a schedule of the
reduction in the liability related to this charge (in millions):

</TABLE>

A substantial amount of the balance at September 30, 2002 relates to severance
that has not been paid to the Company's former Chief Executive Officer and
Chief Financial Officer.

   Write-off of other obsolete assets.  The Company recognized a pre-tax charge
of $12 million ($8 million after-tax) in the second quarter 2002 related to the
retirement of partially depreciated information technology equipment and
software replaced during the quarter with new system applications and
arrangements as well as miscellaneous deposits that are not expected to provide
future value. The charge was recorded in Other Expenses in the accompanying
Condensed Consolidated Statements of Operations.

   As a result of the Company's decision to exit third party risk management
aspects of the marketing and trading business, its investment in Dynegydirect
was written-off in the third quarter 2002, resulting in a pre-tax charge of $29
million ($19 million after-tax). The charge was recorded in Other Expenses in
the accompanying Condensed Consolidated Statements of Operations.

   Corporate Restructuring.  In October 2002, Dynegy Inc. announced that it is
implementing a restructuring plan designed to improve operational efficiencies
and performance across its lines of business. As part of this restructuring the
Company will adopt a decentralized business structure consisting of a
streamlined corporate center and operating units in power generation and
natural gas liquids. As a result of this restructuring, the Company will
recognize pre-tax charges of approximately $38 million ($25 million after-tax)
and $5 million ($3 million after-tax) in the fourth quarter 2002 and first
quarter 2003, respectively, for severance benefits for approximately 780
employees who were from various segments and included all staff levels.

   The Company is currently assessing other potential fourth quarter charges,
which may include, but are not limited to, charges associated with the recently
announced reduction in workforce and organizational restructuring and charges
associated with exiting third party risk management aspects of the marketing
and trading business.

Note 6--Commercial Operations, Risk Management Activities and Financial
Instruments

   Provisions in Statement No. 133 affect the accounting and disclosure of
certain contractual arrangements and operations of the Company. Under Statement
No. 133, all derivative instruments are recognized in the balance sheet at
their fair values and changes in fair value are recognized immediately in
earnings, unless the derivatives (which are not a part of the Company's
marketing activities) qualify and are designated as hedges of future cash
flows, fair values or net investments or qualify, and are designated, as normal
purchases or sales. Derivatives treated as normal purchases or sales are
recorded and recognized in income using accrual accounting.

   The nature of the Company's business necessarily involves certain market and
financial risks. The Company routinely enters into financial instrument
contracts in an attempt to mitigate or eliminate these various risks. These
risks and the Company's strategy for mitigating these risks are more fully
described in Note 3 to the Annual Report on Form 10-K for the year ended
December 31, 2001 (the "Form 10-K").

   Changes in stockholder's equity related to derivatives for the nine-month

   The Company adopted Statement No. 133, effective January 1, 2001, resulting
in an after-tax cumulative effect gain of approximately $2 million.

   From time to time the Company enters into various financial derivative
instruments which qualify as cash flow hedges. For derivatives treated as
hedges of future cash flows, the effective portion of changes in fair value is
recorded in other comprehensive income until the related hedged items impact
earnings. Any ineffective portion of a hedge is reported in earnings
immediately. Instruments related to the Company's customer and risk-management
and midstream liquids businesses are entered into for purposes of hedging
forward fuel requirements for certain power generation facilities, locking in
future margin in the domestic midstream liquids business and hedging price risk
in the global liquids business. Interest rate swaps are used to convert the
floating interest rate component of certain obligations to fixed rates.

   Dynegy recognized a charge of less than $1 million relating to hedge
ineffectiveness during the nine months ended September 30, 2002, and no amounts
were excluded from the assessment of hedge effectiveness related to the hedge
of future cash flows. Additionally, no amounts were reclassified to earnings in
connection with forecasted transactions that were no longer considered probable
of occurring.

   The balance in other comprehensive income at September 30, 2002 associated
with these cash flow hedges is expected to be reclassified to future earnings
contemporaneously with the related purchases of fuel, sales of electricity or
liquids and payments of interest as applicable to each type of hedge. Of this
amount, approximately $16 million in losses, net of taxes, is estimated to be
reclassed into earnings over the 12-month period ending September 30, 2003.
Actual amounts ultimately reclassed to earnings over the next 12 months could
vary materially from this estimated amount as a result of changes in market
conditions.

   The Company also enters into derivative instruments which qualify as fair
value hedges. For derivatives treated as fair value hedges, changes in the fair
value of the derivative and changes in the fair value of the related asset or
liability are recorded in current period earnings. The Company uses interest
rate swaps to convert a portion of its fixed-rate debt into variable-rate debt.
During the nine months ended September 30, 2002 and 2001, there was no
ineffectiveness from changes in fair value of hedge positions, and no amounts
were excluded from the assessment of hedge effectiveness. Additionally, no
amounts were recognized in relation to firm commitments that no longer
qualified as fair value hedge items.

   The Company has investments in foreign subsidiaries, the net assets of which
are exposed to currency exchange-rate volatility. The Company uses derivative
financial instruments, to hedge this exposure. For derivatives treated as
hedges of net investments in foreign operations, the effective portion of
changes in the fair value of the derivative is recorded in the cumulative
translation adjustment. Any ineffective portion of a hedge is reported in
earnings immediately. For the nine months ended September 30, 2002,
approximately $31 million of

       NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

           For the Interim Periods Ended September 30, 2002 and 2001

net losses related to these contracts were included in the cumulative
translation adjustment. During the nine months ended September 30, 2002,
ineffectiveness from changes in fair value of net investment hedge positions
was a loss of approximately $7 million. There were no net investment hedges
during the nine months ended September 30, 2001.

Note 7--Unconsolidated Investments

   Investments in affiliates that are not controlled by the Company but where
the Company has significant influence over operations are accounted for by the
equity method. The Company's share of net income from these affiliates is
reflected in the Condensed Consolidated Statements of Operations as Earnings
(Losses) from Unconsolidated Investments. The Company's principal equity method
investments consist of entities that operate generation assets and natural gas
liquids assets. These equity investments totaled $690 million and $768 million
at September 30, 2002 and December 31, 2001, respectively. The Company entered
into these ventures principally for the purpose of sharing risk and leveraging
existing commercial relationships. These ventures maintain independent capital
structures and have financed their operations on a non-recourse basis to the
Company.

   Generation Assets.  Generation investments primarily include ownership
interests in 8 joint ventures that own fossil fuel electric generation
facilities as well as a limited number of international ventures. The Company's
ownership is 50 percent in the majority of these ventures. The Company's
aggregate net investment of $574 million at September 30, 2002 represents
approximately 2,400 MW of net generating capacity. Dynegy's most significant
investment in generating capacity is its interest in West Coast Power,
representing approximately 1,400 MW of net generating capacity in California.
The net investment in West Coast Power totaled approximately $355 million and
$330 million at September 30, 2002 and December 31, 2001, respectively. West
Coast Power provided equity earnings of approximately $49 million and $157
million in the nine months ended September 30, 2002 and 2001, respectively. NRG
Energy Inc., the parent company of Dynegy's joint venture partner in two joint
ventures, including West Coast Power, recently announced that it has presented
a restructuring proposal to representatives of its bank lenders and
bondholders. NRG Energy also indicated that a Chapter 11 filing may ultimately
be the means for it to implement any restructuring proposal with its creditors.
Dynegy cannot predict with any degree of certainty the effects of these or
similar actions by NRG Energy on the operations or collateral obligations of
these two joint ventures.

   Midstream Investments.  Midstream investments include a 23 percent ownership
interest in a venture that operates a natural gas liquids ("NGL") processing,
extraction, fractionation and storage facility in the Gulf Coast region as well
as a 39 percent ownership interest in a venture that fractionates NGLs on the
Gulf Coast. At September 30, 2002 and December 31, 2001, the Company's
aggregate net investment in these midstream businesses totaled approximately
$116 million and $146 million, respectively. The $146 million of investments at
December 31, 2001 included Dynegy's investment in West Texas LPG Pipeline
Limited Partnership ("WTLPS"), which was transferred to ChevronTexaco
Corporation in August 2002. Please see Note 9 for further discussion of this
transaction.

midstream investments and Dynegy's equity share thereof was ($ in millions):

   In addition to its equity share of net income from these investments, the
Company recognized an impairment charge of $62 million, which is also included
in Earnings (Losses) from Unconsolidated Investments. See Note 5 for further
discussion regarding the impairment of certain of these assets in the third
quarter 2002.

   Other Investments.  In addition to these equity investments, the Company
holds interests in non-public companies for which it does not have significant
influence over operations. These investments are generally accounted for by the
cost method. Such investments totaled $12 million and $32 million at September
30, 2002 and December 31, 2001, respectively. The change is primarily
attributed to the impairment of technology investments resulting from
unfavorable market conditions. See Note 5 for further discussion regarding
these impairments.

   The Company also owned equity securities that had readily determinable fair
market values and were considered available-for-sale. During the nine months
ended September 30, 2002, the Company impaired the carrying value of these
investments, consistent with a continuing decline in market values, and
eventually sold substantially all of these investments realizing a loss of $2
million. At September 30, 2002, there is no remaining carrying value associated
with these investments.

   The Company's decision to exit third party risk management aspects of the
marketing and trading business is expected to reduce significantly its future
requirements to post collateral in the form of cash or letters of credit.
Accordingly, upon successful execution of the Company's exit from this
business, a corresponding reduction in the Company's second quarter 2003
maturities is anticipated. Please read "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital Resources"
for a discussion of the Company's liquidity and capital plan.

   During the nine-month period ended September 30, 2002, the Company repaid
commercial paper borrowings and revolving credit facilities of approximately
$455 million and borrowed approximately $53 million under the revolving credit
facilities. Additionally, during the nine months ended September 30, 2002,
Dynegy issued an aggregate of $501 million of letters of credit under the
revolving credit facilities. During the period from September 30, 2002 through
November 13, 2002, Dynegy repaid $75 million under the revolving credit
facilities in order to allow for capacity to issue additional letters of
credit. Additionally, as described below, Dynegy used $250 million in proceeds
from sales of its United Kingdom natural gas storage facilities to repay an
interim financing that represented an advance on a portion of the proceeds from
such sales.

   Interim Financings.  In July 2002, the Company completed a $200 million
interim financing, bearing interest at LIBOR plus 1.38 percent. This loan
matures in January 2003 and is secured by interests in Dynegy's Renaissance and
Rolling Hills merchant power generation facilities.

   In June 2002, the Company completed a $250 million interim financing,
bearing interest at LIBOR plus 1.75 percent. This loan matures in June 2003 and
represents an advance on a portion of the proceeds from the sale of the
Company's United Kingdom natural gas storage facilities. In September 2002,
Dynegy sold the entity that owned the Hornsea storage facility and in October
2002 repaid approximately $189 million of this interim financing with the net
proceeds. On November 14, 2002, Dynegy sold the entities that owned the Rough
facilities and repaid the remaining balance of this financing with a portion of
the proceeds therefrom.

   Revolvers.  On April 29, 2002, the Company closed a $900 million unsecured
revolving credit agreement with a syndicate of commercial banks. This facility
matures on April 28, 2003. Generally, borrowings under the credit agreement
bear interest at a Eurodollar rate plus a margin that is determined based on
designated unsecured debt ratings of Dynegy. Facility fees are payable on the
full amount of the facility and are determined based on designated unsecured
debt ratings. As of September 30, 2002, amounts outstanding under this facility
included $203 million of borrowings and $517 million in letters of credit.
During October 2002, Dynegy repaid $75 million of outstanding borrowings under
this facility in order to allow for capacity to issue additional letters of
credit. As of November 14, 2002 amounts outstanding under this facility
included $128 million of borrowings and $661 million in letters of credit.

   Financial covenants under this revolver include debt-to-capitalization tests
(which take into account certain lease and similar commitments of Dynegy and
its subsidiaries) and a 3.5 times EBITDA-to-interest test. The permissible
threshold for the debt-to-capitalization is 60%. Other covenants in the
facility include subordination of certain intercompany debt owed to Dynegy and
its subsidiaries, restrictions on liens and limitations prohibiting

                                      23

subsidiary debt at Dynegy Marketing & Trade, Dynegy Power Marketing, Inc. and
Dynegy Midstream Services, Limited Partnership. Default provisions include
cross-payment default of Dynegy, or any principal subsidiary with respect to
debt or other similar obligations that exceed $100 million, cross acceleration
of Dynegy, or any principal subsidiary under any instrument covering debt or
similar obligations that exceed $100 million and bankruptcy or receivership of
Dynegy, or any principal subsidiary. The facility does not contain any defaults
relating to material adverse changes in the condition of Dynegy after the
closing date or to changes in Dynegy's credit ratings. The facility also does
not contain a "term-out" provision that would permit Dynegy to extend the
maturity for borrowings under the facility beyond the facility's April 28, 2003
maturity date. As such, the amounts outstanding under this facility are
classified as current.

   Dynegy was in compliance with the covenants contained in its revolving
credit agreements and other debt instruments at September 30, 2002. Dynegy's
recent operating losses and any further operating losses will make it more
difficult for Dynegy to continue to satisfy the financial covenants in its
revolving credit agreements, particularly the EBITDA-to-interest covenant.
Management will continue to analyze its covenants relative to its results of
operations. The Company is required to deliver a certificate to the lenders
under its revolving credit facilities attesting to its compliance with the
financial covenants under these facilities on a quarterly basis. Any failure to
satisfy one or more of these covenants would constitute a breach giving rise to
a default under the applicable debt instrument and would permit the lenders
under such debt instrument to accelerate the maturity of Dynegy's outstanding
obligations thereunder. Depending upon the particular debt instrument, such a
breach or any action by the lenders to accelerate the maturity of amounts owing
would result in a default under or trigger cross-acceleration provisions in a
significant portion of the Company's other outstanding debt instruments. In the
event of non-compliance, Dynegy would seek waivers from the lenders under these
facilities or attempt to repay or refinance the affected facilities. The
Company cannot provide any assurance that it could repay, obtain waivers or
amendments with respect to or refinance these facilities in the event of any
such default.

   ABG Gas Supply Credit Agreement.  On April 10, 2001, ABG entered into a
credit agreement with a consortium of lenders in order to provide financing
associated with Project Alpha (the "ABG Credit Agreement"). Advances under the
agreement allowed ABG to purchase NYMEX natural gas contracts with the
underlying physical gas supply to be sold to Dynegy Marketing and Trade under
an existing natural gas purchases and sales agreement. The ABG Credit Agreement
requires ABG to repay the advances in monthly installments commencing February
2002 through December 2004 from funds received from Dynegy Marketing and Trade
under the natural gas purchases and sales agreement. The advances bear interest
at a Eurodollar rate plus a margin as defined in the agreement. Advances of
$272 million were outstanding under the ABG Credit Agreement at September 30,
2002.

   DHI Senior Notes.  On February 21, 2002, Dynegy issued $500 million of 8.75%
senior notes due 2012. Interest on the notes is due on February 15 and August
15 of each year, beginning August 15, 2002. The notes are unsecured and are not
subject to a sinking fund.

   Capital Leases.  In response to the initiatives currently underway at the
FASB, on June 28, 2002 the Company unilaterally undertook certain actions, the
effect of which altered the accounting for some of its existing lease
obligations and anticipated lease obligations relating to assets under
construction. These actions included the delivery of guarantees of lessor debt
in certain existing leases of power generation facilities. In addition, the
Company notified certain lenders of its intent to purchase power generation
facilities that are currently under construction and that were expected to be
placed in synthetic leases upon completion of their construction. As a result
of these actions, approximately $528 million of obligations due in 2005 to 2007
were brought on-balance sheet.

   This non-cash action resulted in an increase to Property, Plant and
Equipment and a corresponding increase in Long-Term Debt on the Company's
Condensed Consolidated Balance Sheet. These obligations were previously
reported as lease obligations in the footnotes to the Company's financial
statements and in the Commercial Financial Obligations and Contingent Financial
Commitments tables in the Form 10-K. In addition, actions taken by the Company
relating to assets under construction required the reclassification of
approximately $673 million from Prepayments and Other Assets to Property, Plant
and Equipment on the Company's Condensed Consolidated Balance Sheet. Property
under capital leases of $525 million at September 30, 2002 is included in
Property, Plant and Equipment and is amortized over the useful life of the
asset, which approximates 40 years.

   The following is a schedule of future minimum lease payments under capital
leases together with the present value of the net minimum lease payments as of
September 30, 2002 (in millions):

   Other.  Dynegy completed an amendment to the Catlin Associates, LLC minority
interest transaction (also referred to as "Black Thunder") in June 2002, which
permanently removed a $270 million obligation which could have been triggered
by declines in Dynegy's credit ratings. The amended agreement requires a
subsidiary of Dynegy to make periodic payments totaling $275 million over the
remaining three years of the transaction. The subsidiary has already paid
approximately $73 million of this total. Quarterly maturities are approximately
$20 million through the first quarter 2005. In addition, Dynegy agreed to grant
mortgages on the midwest generation assets covered by the transaction, post a
letter of credit to secure a contingent obligation expiring December 31, 2002
and make certain structural changes to enhance the security of the third-party
lenders involved in the transaction. As a result of this amendment, $796
million related to Catlin Associates, LLC was reclassified from Minority
Interest to debt on Dynegy's Condensed Consolidated Balance Sheet.

   Also in June 2002, West Coast Power, LLC ("West Coast Power"), a joint
venture owned equally by Dynegy and NRG Energy with generation assets in
California, repaid a non-recourse project financing with cash on hand within
the joint venture entity. This payment eliminated a $31 million obligation
which could have been triggered by declines in Dynegy's credit ratings.
Concurrent with the retirement of the project financing, West Coast Power
entered into an amended $120 million bank facility consisting of a $100 million
letter of credit facility that will be used to collateralize West Coast Power's
obligations, a $10 million term loan and a $10 million working capital
facility. The facility has resulted in the release of approximately $100
million in letters of credit previously posted by Dynegy on behalf of West
Coast Power. Please see "Note 7--Unconsolidated Investments" for a discussion
of recent developments involving NRG Energy.

   Dynegy incurred upfront fees aggregating approximately $19 million in
connection with the interim financings, Black Thunder amendment and West Coast
Power transactions described above. Such amounts are capitalized and amortized
over the term of the respective financing transactions.

Note 9--Related Party Transactions

   ChevronTexaco Commercial Arrangements.  In March 2002, Dynegy and
ChevronTexaco agreed to expand their commercial relationships to include
substantially all of the natural gas and domestic mixed NGLs and NGL products
produced or controlled by the former Texaco.

   In August 2002, Dynegy and ChevronTexaco executed an agreement pursuant to
which the parties amended the existing gas purchase agreement, security
agreement, netting agreement and certain related agreements. Under this new
agreement, Dynegy agreed to accelerate payment to the month of delivery for a
portion of the natural gas it purchases from ChevronTexaco, with the amount of
the accelerated payment generally being equal to 75 percent of the value of the
prior month's gas deliveries, after reduction pursuant to a netting agreement
between Dynegy and ChevronTexaco. This payment arrangement was effective upon
the closing of the sale of Northern Natural described in Note 4 above. The
accelerated payment totaled $152 million at September 30, 2002.

   In connection with Dynegy's announced exit from third party risk management
aspects of the marketing and trading business, Dynegy and ChevronTexaco have
been negotiating to terminate the natural gas purchase agreement between the
parties and to provide for an orderly transition of responsibility for
marketing ChevronTexaco's domestic natural gas production. These discussions
will not affect Dynegy's current contractual agreements with ChevronTexaco
relative to ChevronTexaco's U.S. natural gas processing and the marketing of
ChevronTexaco's domestic NGLs.

   Also in August 2002, in partial satisfaction of certain of its obligations
to ChevronTexaco under these agreements, Dynegy sold to ChevronTexaco its 39.2%
ownership interest in WTLPS, which is the owner of West Texas LPG Pipeline.
ChevronTexaco was already the owner of the largest interest in WTLPS and the
operator of the pipeline. The interest sold to ChevronTexaco was valued at $45
million. This non-cash transaction reduced Accounts Payable to Affiliates and
Unconsolidated Investments by $45 million.

   Other.  At September 30, 2002, the Company had several financing
arrangements under which it was owed approximately $12 million from one of its
equity investees, Nicor Energy. The interest rate varies from zero to prime
plus two percent. The repayment terms for $4 million are over the next fifteen
months, while the remaining $8 million is due when Nicor Energy is sold.

Note 10--Commitments and Contingencies

   Please see Note 11, "Commitments and Contingencies," in the Form 10-K and
Notes 8 and 11, "Commitments and Contingencies," in the Company's Forms 10-Q
for the quarters ended March 31, 2002 and June 30, 2002 (the "Forms 10-Q"),
respectively, for a description of the Company's material legal proceedings.
Set forth below is a description of any material developments that have
occurred with respect to such proceedings since the Company's filing of the
Form 10-Q for the second quarter 2002 and a description of any new matters that
have arisen during the quarter. Except as otherwise indicated, the Company
cannot currently predict with any degree of certainty the outcome of the
proceedings or the amount of any potential liabilities.

   In addition to the matters described below, the Company is party to legal
proceedings arising in the ordinary course of business. In the opinion of
management, the disposition of any such matters will not have a material
adverse effect on the Company's financial condition, results of operations or
cash flows. The Company recognizes estimated losses from contingencies when
information available indicates that a loss is probable and the amount of the
loss is reasonably estimable in accordance with SFAS No. 5, "Accounting for
Contingencies."

   Baldwin Station Litigation.  Illinois Power and Dynegy Midwest Generation,
Inc. (collectively, the "Defendants") are currently the subject of a Notice of
Violation ("NOV") from the Environmental Protection Agency (the "EPA") and a
complaint filed by the EPA and the Department of Justice alleging violations of
the Clean Air Act (the "Act") and the regulations promulgated under the Act.
Similar notices and complaints have been filed against a number of other
utilities. Both the NOV and the complaint allege that certain equipment
repairs, replacements and maintenance activities at the Defendants' three
Baldwin Station generating units constituted "major modifications" under the
Prevention of Significant Deterioration and/or the New Source Performance
Standards regulations. When activities that meet the definition of "major
modifications" occur and they are not otherwise exempt, the Act and related
regulations generally require that generating facilities meet more stringent
emissions standards, which may entail the installation of potentially costly
pollution control equipment. The Defendants filed an answer denying all claims
and asserting various specific defenses and a trial date of June 3, 2003 has
been set.

   The Company believes that it has meritorious defenses to the EPA allegations
and will vigorously defend against these claims. The Company has undertaken
activities to significantly reduce emissions at the Baldwin Station since the
complaint was filed in 1999. In 2000, the Baldwin Station was converted from
high to low sulfur coal. This conversion resulted in sulfur dioxide emission
reductions of over 90% from 1999 levels. Furthermore, selective catalytic
reduction equipment has been installed at two of the three units at Baldwin
Station resulting in significant emission reductions of nitrogen oxides.
However, the EPA may seek to require the installation of the "best available
control technology" (or the equivalent) at the Baldwin Station. Independent
experts hired by Dynegy originally estimated capital expenditures of up to $380
million if the installation of best available control technology is required.
Current estimates suggest that such capital expenditures could be as much as
$410 million. The EPA also has the authority to seek penalties for the alleged
violations in question at the rate of up to $27,500 per day for each violation.
The Company has filed a motion for summary judgment based on the five-year
statute of limitations, which could affect the EPA's ability to collect
penalties. The Company has recorded a reserve for potential penalties that
could be imposed if the EPA were to successfully prosecute its claims.

   None of the Defendants' other facilities are covered in the complaint and
NOV, but the EPA has officially requested information concerning activities at
the Defendants' Vermilion, Wood River, and Hennepin Plants as well as the
Danskammer and Roseton Plants operated by other Dynegy subsidiaries. It is
possible that the EPA will eventually commence enforcement actions based on
activities at those plants as well.

   On June 13, 2002, the EPA announced its intention to implement several
reforms to its regulations governing new source review. These reforms, if made,
would clarify the routine maintenance, repair and replacement exclusion,
provide more certainty in evaluating permit requirements and increase
operational flexibility for affected facilities.

   California Market Litigation.  Six class action lawsuits were filed in 2000
and 2001 against various Dynegy entities based on the events occurring in the
California power market. The complaints allege violations of California's
Business and Professions Code, Unfair Trade Practices Act and various other
statutes. The plaintiffs allege that the defendants, including the owners of
in-state generation and various power marketers, conspired to manipulate the
California wholesale power market to the detriment of California consumers.
Included among the acts forming the basis of the plaintiffs' claims are the
alleged improper sharing of generation outage data, improper withholding of
generation capacity and the manipulation of power market bid practices. The
plaintiffs seek unspecified treble damages.

   All six lawsuits were consolidated before Judge Sammartino, Superior Court
Judge for the County of San Diego. Subsequent to the consolidation two
defendants filed cross complaints against a number of corporations and
governmental agencies that sold power in California's wholesale energy markets.
Four cross defendants removed the six cases to the United States District Court
for the Southern District of California (San Diego). Following removal, certain
cross defendants filed motions to dismiss the cross complaints, which motions
are currently pending. The original plaintiffs in the six consolidated
complaints have filed motions to remand the consolidated cases back to state
court, which motions are currently pending. The defendants in the six
consolidated cases have filed motions to dismiss the complaints based on the
filed rate doctrine and preemption defense. The motion to remand and the cross
defendants' motion to dismiss were heard by the Court and taken under
submission by Federal Judge Whaley on September 19, 2002. If the Court decides
that it has jurisdiction over the claims, the defendants' motion to dismiss
will be heard as soon as possible thereafter.

   On March 11, 2002, the California Attorney General filed, on behalf of the
People of the State of California, complaints in San Francisco Superior Court
against several owners of power generation facilities, including subsidiaries
of West Coast Power. The complaints allege that since June 1998, these
generators sold power in the open market that should have been held in
emergency reserve for the State. In the aggregate, the complaints seek more
than $150 million in penalties, restitution and return of profits from the
generators. These lawsuits were subsequently removed to the United States
District Court for the Northern District of California. The California Attorney
General filed motions to remand the cases back to state court. By Order issued
on August 6, 2002, Judge Walker denied the motions to remand, thus keeping the
cases in federal court. The defendants have filed motions to dismiss, which
were argued and taken under submission by Judge Walker.

   In addition to the six consolidated lawsuits discussed above, eight new
putative class actions were filed on behalf of business and residential
electricity consumers, including consumers residing in the State of Washington.
The lawsuits were filed in various state courts in Northern California, and in
respect to the lawsuit on behalf of consumers in the State of Washington, in
the United States District Court for the Northern District of California. Named
as defendants are various generators and marketers, including Dynegy and
certain affiliates. The complaints allege unfair, unlawful and deceptive
practices in violation of the California Unfair Business Practices Act and seek
to enjoin illegal conduct, restitution and unspecified damages. While some of
the allegations in these lawsuits are similar to the allegations in the other
six lawsuits, these lawsuits include additional allegations based on events
occurring subsequent to the filing of the other six lawsuits. These additional
allegations include allegations similar to those made by the California
Attorney General in the March 11, 2002 lawsuit described above as well as
allegations that contracts between these generators and the

California Department of Water Resources (the "DWR") constitute unfair business
practices resulting from market manipulation. The lawsuits filed in state court
have been removed to federal courts in the Northern and Eastern Districts of
California. Certain defendants have filed a petition with the Judicial Panel
For Multidistrict Litigation seeking to consolidate the new cases with the six
cases consolidated in the United States District Court for the Southern
District of California. By order dated October 11, 2002, the Judicial Panel for
Multidistrict Litigation ordered the new cases consolidated with the original
six cases in the United States District Court for the Southern District of
California.

   Dynegy intends to vigorously defend against the claims made with respect to
its activities in the California power markets. However, an adverse result in
any of these proceedings could have a material adverse effect on the Company's
financial condition and results of operations.

   Enron Litigation.  Dynegy Inc. and the Company were sued on December 2, 2001
by Enron and Enron Transportation Services Co. in the United States Bankruptcy
Court for the Southern District of New York, Adversary Proceeding No. 01-03626
(AJG). Enron claimed that Dynegy Inc. materially breached the Merger Agreement
dated November 9, 2001 between Enron and Dynegy and related entities by
wrongfully terminating that Agreement on November 28, 2001. Enron also claimed
that the Company wrongfully exercised its option to take ownership of Northern
Natural under an Option Agreement dated November 9, 2001. Enron sought damages
in excess of $10 billion and declaratory relief against Dynegy Inc. for breach
of the Merger Agreement. Enron also sought unspecified damages against Dynegy
Inc. and the Company for breach of the Option Agreement. Dynegy Inc. filed an
answer on February 4, 2002, denying all material allegations. On April 12,
2002, the Bankruptcy Court granted Dynegy Inc.'s motion to transfer venue in
the proceeding to the United States District Court for the Southern District of
Texas (Houston Division).

   On August 15, 2002, Dynegy Inc. and Enron entered into an agreement to
settle this lawsuit. Under the terms of the settlement agreement, Dynegy Inc.
agreed to pay Enron $25 million, $10 million of which was paid to Enron upon
approval of the settlement agreement by the Bankruptcy Court, with the
remaining $15 million escrowed until approval of the settlement becomes final.
In addition, the parties agreed to exchange mutual releases of any and all
claims related to the terminated merger and to dismiss such litigation. Dynegy
also agreed not to pursue any claims for working capital adjustments relating
to its acquisition of Northern Natural. The terms of the settlement were
approved by the Bankruptcy Court on August 29, 2002. On September 6, 2002, an
appeal of the Bankruptcy Court's approval was filed by the plaintiffs who had
filed the class action lawsuits described below, and such appeal remains
pending. The effect of the appeal is to delay the effective date of the
settlement, the release of the remaining $15 million to Enron and the dismissal
of the pending Enron lawsuit.

   Dynegy previously described a suit filed against Dynegy Inc. and the Company
by Ann C. Pearl and Joel Getzler in the United States District Court for the
Southern District of New York, Cause No. 01 CV 11652. Plaintiffs filed the
lawsuit as a purported class action on behalf of all persons or entities who
owned common stock of Enron Corp. as of November 28, 2001. A similar suit was
filed by Bernard D. Shapiro and Peter Strub in the 129th Judicial District
Court for Harris County, Texas, Cause No. 2002-00080. Plaintiffs in each case
alleged that they are intended third party beneficiaries of the Merger
Agreement dated November 9, 2001 between Enron and Dynegy and related entities.
Plaintiffs claimed that Dynegy Inc. materially breached the Merger Agreement
by, inter alia, wrongfully terminating that agreement. Plaintiffs also claimed
that Dynegy Inc. breached the implied covenant of good faith and fair dealing.
Plaintiffs sought an award of damages and other relief. Enron moved for an
order of the Bankruptcy Court in the Southern District of New York, directing
that the Pearl and Shapiro plaintiffs be enjoined from prosecuting their
actions and immediately dismiss those actions. The Bankruptcy Court held that
the claims asserted by the Pearl and Shapiro plaintiffs were the exclusive
property of the Enron bankruptcy estate, and that the plaintiffs lacked
standing to sue as third party beneficiaries of the Merger Agreement.
Accordingly, by an order entered on April 19, 2002, the Bankruptcy Court
granted Enron's

motion, enjoined the prosecution of both actions, and directed that they be
dismissed. The Pearl and Shapiro plaintiffs thereafter complied with that
order, but filed an appeal to the United States District Court for the Southern
District of New York. On October 22, 2002, the District Court reversed the
Bankruptcy Court's determination, holding that the Pearl and Shapiro plaintiffs
do have standing to sue as third party beneficiaries, and that their claims are
not the exclusive property of the estate. That ruling is subject to further
review by the United States Court of Appeals for the Second Circuit, should
Enron elect to file an appeal. Shortly after this ruling, certain Enron
shareholders filed an action against Dynegy Inc. for wrongful termination of
the Merger Agreement in the United States District Court for the Southern
District of New York.

   On October 28, 2002, Dynegy Inc. and the Company filed a declaratory action
in Harris County Judicial District Court relating to the Shapiro action. The
action seeks to reinstate the Shapiro action in the 129/th/ Judicial District
Court that is no longer stayed. The action also seeks affirmative declarations
to the effect that Dynegy Inc. did not wrongfully terminate the Merger
Agreement, that the termination did not breach any duty owed to the Shapiro
plaintiffs or to Enron's shareholders generally and that neither the Shapiro
plaintiffs nor Enron's shareholders generally have a right to enforce or to
make claims under the Merger Agreement.

   Should the settlement with Enron fail to be consummated, and/or should the
Pearl and Shapiro lawsuits proceed, Dynegy nevertheless believes that all such
claims arising out of the terminated merger are without merit and will
vigorously defend against these claims. An adverse result in any of these
proceedings, however, could have a material adverse effect on the Company's
financial position or results of operations.

   As a result of Enron's bankruptcy filing, Dynegy recognized in its fourth
quarter 2001 financial statements a pre-tax charge related to the Company's net
exposure for commercial transactions with Enron. As of September 30, 2002, the
Company's net exposure to Enron, inclusive of certain liquidated damages and
other amounts relating to the termination of the transactions, was
approximately $94 million and was calculated by setting off approximately $230
million owed from various Dynegy entities to various Enron entities against
approximately $314 million owed from various Enron entities to various Dynegy
entities. The master netting agreement between Dynegy and Enron and the
valuation of the commercial transactions covered by the agreement, which
valuation is based principally on the parties' assessment of market prices for
such period, remain subject to dispute by Enron with respect to which there
have been negotiations between the parties. These negotiations have focused on
the scope of the transactions covered by the master netting agreement and the
parties' valuations of those transactions. If any disputes cannot be resolved
by the parties, the agreements call for arbitration. Dynegy has instituted
arbitration proceedings against those Enron parties not in bankruptcy, and has
filed a motion with the Bankruptcy Court requesting that it be allowed to
proceed to arbitration against those Enron parties that are in bankruptcy. In
response, the Enron Chapter 11 debtors have filed an objection to Dynegy's
request to proceed to arbitration. This objection (as well as an adversary
proceeding simultaneously filed with the Bankruptcy Court) requests that the
related arbitration proceedings not be allowed to proceed and that the dispute
be settled in Bankruptcy Court. The filing also alleges that the default,
set-off and joint and several liability provisions of the master netting
agreement are unenforceable and that, as a result, Dynegy should be required to
pay to the Enron parties the monies otherwise owed under the Underlying Master
Agreements. If the setoff rights were modified or disallowed, either by
agreement or otherwise, the amount available for Dynegy entities to set off
against sums that might be due Enron entities could be reduced materially.

   Farnsworth Litigation.  On August 2, 2002, Bradley Farnsworth filed a
lawsuit against Dynegy Inc. in Texas state district court claiming breach of
contract and that he was demoted and ultimately fired from the position of
Controller for refusing to participate in illegal activities. Specifically, Mr.
Farnsworth alleges, in the words of his complaint, that certain former
executive officers of the Company requested that he "shave or reduce

for accounting purposes" the forward price curves associated with the natural
gas business in the United Kingdom for the period of October 1, 2000 through
March 31, 2001, in order to indicate a reduction in the Dynegy Inc.'s
mark-to-market losses. Mr. Farnsworth, who seeks unspecified actual and
exemplary damages and other compensation, also alleges that he is entitled to a
termination payment under his employment agreement equal to 2.99 times the
greater of his average base salary and incentive compensation for the highest
three calendar years preceding termination or his base salary and target bonus
amount for the year of termination. The parties have commenced discovery in
this lawsuit. Dynegy understands that Dynegy Inc. intends to vigorously defend
against these claims. The Company does not believe that any liability it might
incur as a result of this litigation would have a material adverse effect on
its financial condition or results of operations.

   SEC Settlement.  On September 24, 2002, Dynegy Inc. announced that it had
concluded a settlement with the SEC of allegations made against it in
connection with the previously disclosed investigation relating to Project
Alpha and round-trip electricity trades with CMS Energy. In the settlement, the
SEC found that Dynegy Inc. engaged in securities fraud in connection with its
disclosures and accounting for Project Alpha, and negligently included
materially misleading information about the round-trip energy trades with CMS
Energy in two press releases it issued in early 2002. In settlement of the
SEC's enforcement action, Dynegy Inc., without admitting or denying the SEC's
findings, agreed to the entry of a cease-and-desist order and to pay a $3
million penalty in a related civil suit filed in the United States District
Court in Houston, Texas. Dynegy is continuing to cooperate with the SEC's
ongoing investigation of other parties related to Project Alpha.

   CFTC Investigation.  The U.S. Commodity Futures Trading Commission ("CFTC")
commenced an investigation in June 2002 relating to the Company's trading
activities. The investigation covers Dynegydirect and round-trip trading and
was recently expanded to cover Dynegy's practices with respect to furnishing
information regarding natural gas trades to various energy industry
publications that compile and report index prices. Dynegy Inc. previously
announced that, during an internal review of its trading activities that is
being conducted in connection with the CFTC investigation, it discovered that
certain employees in its trading business had furnished inaccurate information
to various industry publications. The Company is one of many energy industry
participants who routinely provide trade data to the publications;
consequently, the Company cannot determine whether the inaccurate data had any
impact on the published indices. In response to these findings, Dynegy now
requires that all price information provided to industry publications be
verified by the office of Dynegy's Chief Risk Officer. In addition, in October
2002 Dynegy dismissed six employees and disciplined seven others in its natural
gas trading business as a result of an investigation conducted by Dynegy Audit
and Compliance Committee and in collaboration with independent counsel. Dynegy
also relieved a corporate compliance officer of his responsibilities in
connection with its investigation into this matter. The Company has produced
documents in connection with the CFTC's investigation. The Company has assured
the Staff of the CFTC that it intends to cooperate with this investigation. The
Company cannot predict the ultimate outcome of this matter.

   U.S. Attorney Investigations.  The U.S. Attorney's office in Houston has
commenced an investigation of the Company relating to Project Alpha, roundtrip
trades with CMS Energy and Dynegy's gas trade reporting practices. The Company
has produced documents and witnesses for interviews in connection with this
investigation. The Company is cooperating fully with the U.S. Attorney's office
in its investigation of these matters. The Company cannot predict the ultimate
outcome of this matter.

   Additionally, the U.S. Attorney's office in the Northern District of
California has issued a subpoena to the Company requesting information related
to California energy markets. The Company intends to cooperate fully with the
U.S. Attorney's office in its investigation of these matters. The Company
cannot predict the ultimate outcome of this matter.

  FERC and Related Regulatory Investigations.

   Requests for Refunds.  On July 25, 2002, the FERC initiated a hearing to
establish refunds to electricity customers, or offsets against amounts owed to
electricity suppliers, during the period of October 2, 2000 through June 19,
2001. In particular, the FERC established a methodology to calculate mitigated
market clearing prices in the California Independent System Operator (the
"ISO") and the California Power Exchange (the "PX") markets. During March 2002
and August 2002, hearings on this matter were held before an administrative law
judge. The administrative law judge has stated that his findings of fact will
be issued before the end of 2002. Such findings will then be forwarded to the
FERC Commissioners for final determination.

   In August 2002, the FERC requested comments on a proposal made by the FERC
staff to change the method for determining natural gas prices for purposes of
computing the mitigated market-clearing price that it intends to utilize in
calculating refunds for sales of power in California power markets during the
period from October 2, 2000 to June 19, 2001. As drafted, the proposal would
replace the gas prices used in the computation, thus reducing the mitigated
market clearing price for power and increasing calculated refunds, subject to a
provision that generally would provide full recoverability of gas costs paid by
the generators to unaffiliated third parties. If adopted, this methodology
could have a material effect on any refunds or offsets that the FERC might
order from Dynegy or West Coast Power pursuant to its investigation of the
California power markets.

   Alleged California Market Manipulation and Round-Trip Trades.  On February
13, 2002, the FERC initiated an investigation of possible manipulation of
natural gas and power prices in the western United States during the period
from January 2001 through the present. On May 8, 2002, in response to three
memoranda (authored by individuals employed by or previously employed by Enron)
discovered by the FERC allegedly containing evidence of market manipulation by
Enron in California, the FERC issued requests for information to all sellers in
the ISO and the PX markets during 2000 and 2001 seeking information with
respect to whether those sellers engaged in trading strategies described in the
three Enron memoranda. Dynegy has responded to these requests, indicating that
it did not engage in any of the trading strategies described in the three Enron
memoranda. In August 2002, the FERC staff issued its preliminary report on its
investigation into trading practices in the three Enron memoranda.

   On May 21, 2002, the FERC issued requests for information to all sellers of
wholesale electricity or ancillary services in the Western Systems Coordinating
Council (the "WSCC"), and on May 22, 2002 the FERC issued requests for
information to all sellers of natural gas in the WSCC or Texas, seeking
information with respect to whether those sellers engaged in "wash,"
"round-trip" or "sale/buyback" transactions during 2000-2001. Requests for
similar information with respect to electric power trading activities in the
Electric Reliability Council of Texas were received from the Texas Public
Utility Commission in June 2002.

   Dynegy responded to each of these requests. Based on its investigation to
date, Dynegy believes that its trading practices are consistent with applicable
law and tariffs. In addition, Dynegy's investigations concluded that it did not
engage in "wash," "round-trip" or "sale/buyback" transactions in the WSCC, for
electricity or ancillary services, and the WSCC or Texas for natural gas
transactions. Neither the California State Senate committee nor the Texas
Public Utility Commission has issued its preliminary findings on its
investigation, and Dynegy cannot predict with certainty how such allegations
will ultimately be resolved. Dynegy will continue to cooperate fully with these
investigations.

   On August 13, 2002, the FERC staff issued its preliminary report on its
investigation into the Enron memoranda and "wash," "round-trip" or
"sale/buyback" transactions. The FERC has stated that a final staff report will
not be issued before March 2003.

   On September 17, 2002, California Public Utilities Commission President
Loretta Lynch released a report indicating that Dynegy and five other energy
firms did not produce all available power on days in which the State of
California experienced power service interruptions between November 1, 2000 and
May 31, 2001. No mention is made of prosecuting the named firms in the report.
However, the SEC and FERC have requested additional information and comment
with respect to the report. Dynegy disputes the report's findings and is
cooperating with the SEC and the FERC in connection with their requests.

   Trade Press.  In September 2002, the FERC staff issued requests for
information on issues related to reporting of information on natural gas trades
to energy industry publications that compile and report index prices. Dynegy
has responded to many of these requests and is cooperating with the FERC staff
in connection with this matter.

   Western Long-Term Contract Complaints.  On February 25, 2002 the California
Public Utilities Commission and the California Electricity Oversight Board
filed complaints with the FERC asking that it void or reform power supply
contracts between the DWR and, among others, West Coast Power. The complaints
allege that prices under the contracts exceed just and reasonable prices
permitted under the Federal Power Act. The FERC set these complaints for
evidentiary hearing. While West Coast Power continues in good faith
negotiations with the State of California on reforming the terms of its DWR
contract, settlement ultimately may not be possible. An administrative law
judge has been directed to issue an order by February 14, 2003 as to whether
West Coast Power's or other contacts with the DWR must be reformed. While the
Company believes the terms of its contracts are just and reasonable and do not
reflect alleged market manipulation, it cannot predict the outcome of this
matter.

   In a related complaint, The Kroger Co. filed a complaint with the FERC in
August 2002 asking that the four wholesale contracts between Dynegy Power
Marketing, Inc. and AES New Energy, Inc., which provides retail service to The
Kroger Co., be declared void for their remaining terms, and that the FERC set
just and reasonable rates for prior periods. Alternatively, The Kroger Co. asks
that the FERC allow for an annual review procedure to reset the contract
prices. The complaint alleges that but for the dysfunctional California
electricity markets, it would not have entered into the contracts for delivery
of energy through December 2006. Dynegy intends to vigorously defend against
these claims.

   West Coast Power.  Through its interest in West Coast Power, Dynegy has
credit exposure for past transactions to certain state agencies ("ISO" and
"PX"), which primarily relied on receipts from California utilities to pay
their bills. West Coast Power currently sells directly to the California
Department of Water Resources ("DWR") pursuant to a long-term sales agreement.
Please see "Western Long-Term Contracts Complaints" above for discussion of the
actions taken by various parties with respect to this agreement.

   As a result of West Coast Power's long-term sales arrangement with the DWR,
management believes that Dynegy's primary exposure in the California market
relates to the realization of its share of West Coast Power's receivables from
the ISO and PX and potential refunds or offsets associated with related
transactions. The DWR is current under the terms of its arrangements with West
Coast Power. At September 30, 2002, Dynegy's portion of the receivables owed to
West Coast Power by the ISO and PX approximated $205 million. Management is
continually assessing Dynegy's exposure, as well as its exposure through West
Coast Power, relative to its California receivables and establishes and
maintains reserves as necessary.

Note 11--Regulatory Issues

   The Company is subject to regulation by various federal, state, local and
foreign agencies, including extensive rules and regulations governing
transportation, transmission and sale of energy commodities as well as the
discharge of materials into the environment or otherwise relating to
environmental protection. Compliance with these regulations requires general
and administrative, capital and operating expenditures including those related
to monitoring, pollution control equipment, emission fees and permitting at
various operating facilities and remediation obligations. In addition, the U.S.
Congress has before it a number of bills that could impact regulations or
impose new regulations applicable to Dynegy and its subsidiaries. The Company
cannot predict the outcome of these bills or other regulatory developments or
the effects that they might have on its business. For a more detailed
description of regulatory issues affecting the Company's business, please refer
to "Item 1. Business--Regulation" in the Form 10-K.

Note 12--Segment Information

   Dynegy's operations are divided into three reportable segments: WEN, Dynegy
Midstream Services ("DMS"), and Transmission and Distribution ("T&D"). WEN is
engaged in a broad array of businesses, including physical supply of and
risk-management activities around wholesale natural gas, power, coal and other
similar products. This segment is focused on optimizing the Company's and its
customers' global portfolio of energy assets and contracts, as well as direct
commercial and industrial sales and retail marketing alliances. DMS consists of
the Company's North American midstream gas gathering and processing, NGL
fractionation and NGL marketing businesses and worldwide NGL marketing and
transportation operations. Dynegy's T&D segment includes the operations of
Northern Natural. As described in Note 4, the Company sold Northern Natural in
August 2002. Northern Natural's results are included in the Discontinued
Operation section of the Statements of Operations. Dynegy accounts for
intercompany transactions at prevailing market rates. Unaudited operating
segment information for the three- and nine-month periods ended September 30,
2002 and 2001 is presented below. See Note 4 for an explanation of anticipated

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
           For the Interim Periods Ended September 30, 2002 and 2001

Item 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
       RESULTS OF OPERATIONS

   The following discussion and analysis should be read in conjunction with the
unaudited condensed consolidated financial statements of Dynegy Holdings Inc.
("Dynegy" or the "Company") included herein and with the Company's Current
Report on Form 8-K dated November 19, 2002, which includes unaudited restated
financial statements for 1999-2001 reflecting the known revisions described
elsewhere in this quarterly report (the "Restatement Form 8-K"). As discussed
in the Explanatory Note on the Table of Contents, the comparative financial
information contained in this report has been revised to reflect the known
effects of the restatement items described in Note 1 to the accompanying
Condensed Consolidated Financial Statements. Concurrent with the filing of this
quarterly report, Dynegy has filed the Restatement Form 8-K, which includes
revised financial statements for each of the years in the three-year period
ended December 31, 2001. These revised financial statements have been prepared
by management and reflect all known restatement items as of the date hereof.
However, as a result of the three-year re-audit and PricewaterhouseCoopers'
subsequent review of Dynegy's 2002 quarterly financial statements, it is
possible that additional adjustments to the unaudited financial statements in
the Restatement Form 8-K and Dynegy's 2002 quarterly reports may result, some
of which could be material. Dynegy expects to file an amended Form 10-K
reflecting the unaudited restatements described in the Restatement Form 8-K as
soon as practicable after the date of this report. Following completion of the
re-audit, which the Company expects will occur early in the first quarter 2003,
further amendment of the Form 10-K will be necessary in order to include the
audit report of PricewaterhouseCoopers LLP as well as to reflect other changes
resulting from the re-audit, if any.

                              RECENT DEVELOPMENTS

   A number of significant developments have occurred with respect to Dynegy
since the filing of its second quarter 2002 Form 10-Q. On October 16, 2002,
Dynegy Inc. announced an organizational restructuring plan designed to improve
operational efficiencies and performance across its asset-based lines of
business. The plan provides for the adoption of a decentralized business
structure consisting of a streamlined corporate center and operating units in
power generation, natural gas liquids, regulated energy delivery and
communications.

   Also on October 16th, Dynegy Inc. announced that it would exit third party
risk management aspects of the marketing and trading business. As a result of
its organizational restructuring and exit from third party risk management
aspects of the marketing and trading business, Dynegy Inc. announced a
workforce reduction affecting approximately 780 employees and the resignation
of President and Chief Operating Officer Steve Bergstrom.

   Several events affecting Dynegy precipitated the above actions. These events
include, among others, contraction in the trading markets, downgrades in the
Company's credit ratings, increased collateralization requirements and a weak
commodity price environment for power, as well as various legal proceedings and
investigations involving Project Alpha, Dynegy's trading practices and the
failed merger with Enron Corp. These events have had a severely negative effect
on Dynegy's operating results, liquidity, confidence in Dynegy's ability to
meet its debt and other obligations and its long-term business strategy, all of
which is reflected in continued declines in the market price for Dynegy's debt
securities. These events, affecting Dynegy and the industry in general,
contributed to lower operating results in the third quarter 2002 and have
significantly affected the Company's business and operating capabilities.

   Dynegy has been and remains committed to addressing these issues. Since the
filing of its second quarter 2002 Form 10-Q, Dynegy continued to execute on the
elements of its capital and liquidity plan. In particular, the sale of Northern
Natural Gas Company ("Northern Natural") to MidAmerican Energy Holdings Company

                                      39

           For the Interim Periods Ended September 30, 2002 and 2001

("MidAmerican") in August enabled the Company to meet the sharp increase in
collateral obligations and to improve its liquidity position. This liquidity
position also was improved by the sale of the Company's United Kingdom natural
gas storage assets. The Company's decision to exit third party risk management
aspects of the marketing and trading business is intended to add to the capital
plan by freeing up material amounts of letters of credit and cash collateral
otherwise committed to customers in this business.

   On October 23, 2002, Dynegy Inc. announced the selection of Bruce Williamson
as its new President and Chief Executive Officer. Under Mr. Williamson's
leadership, the Company expects to continue to execute the remaining elements
of the capital plan now enhanced by the exit from third party risk management
aspects of the marketing and trading business and additional general and
administrative expense reductions. On November 14, 2002, Dynegy completed the
sale of the Rough storage facility and certain related assets in the United
Kingdom as described below.

   The goal of Dynegy Inc.'s enhanced capital plan is to enable the Company to
meet its debt obligations as they mature through 2003 and thereafter. Dynegy's
success and its future financial condition will depend on the management of its
exit from third party risk management aspects of the marketing and trading
business and execution of the remaining elements of its capital plan, each of
which is subject to the risks described in this quarterly report. Please read
"Liquidity and Capital Resources" for further details with respect to these
risks and "Uncertainty of Forward-Looking Statements and Information" for
additional factors that could impact Dynegy's future operating results and
financial condition.

                        LIQUIDITY AND CAPITAL RESOURCES

Capital Plan

   In June 2002, Dynegy Inc. announced a $2 billion capital plan designed to
improve liquidity and reduce debt. As part of the capital plan, on June 27,
2002, Dynegy completed an amendment to the Catlin Associates, LLC minority
interest transaction (also referred to as "Black Thunder"), which permanently
removed a $270 million obligation that could have been triggered by declines in
Dynegy's credit ratings. Dynegy subsequently completed a $250 million interim
financing as an advance on a portion of the proceeds from the expected sale of
certain of its United Kingdom natural gas storage facilities and a $200 million
interim financing secured by interests in its Renaissance and Rolling Hills
merchant power generation facilities.

   During the third quarter, Dynegy continued to execute on elements of its
capital plan. On August 16, 2002, Dynegy completed the sale of Northern Natural
to MidAmerican for $928 million in cash, subject to adjustment for changes in
working capital. The sale eliminated approximately $890 million of Northern
Natural debt. In September 2002, the Company sold $90 million in 6.875 percent
Northern Natural senior notes due May 2005 for approximately $96 million in
cash. The Company had acquired the notes at par value in April 2002 in order to
obtain a bondholder consent in connection with the acquisition of Northern
Natural.

   In September 2002, Dynegy sold all of the shares of Dynegy Hornsea Limited,
a subsidiary that owned and operated a portion of its natural gas storage
facilities in the United Kingdom, to SSE Energy Supply Limited, a subsidiary of
Scottish and Southern Energy plc. SSE paid approximately $200 million (130
million (Pounds)). The net proceeds from the sale of approximately $189 million
were used to pay down a portion of the related $250 million interim financing
during October 2002.

   During the second and third quarters of 2002, Dynegy took a number of steps
to reduce general and administrative expenses to more appropriately align the
Company's corporate structure with industry conditions

           For the Interim Periods Ended September 30, 2002 and 2001

and the decline in commercial activity. Included among these measures are the
June 2002 and October 2002 workforce reductions affecting approximately 309 and
780 employees, respectively.

   On November 14, 2002, Dynegy sold all of the shares of two subsidiaries that
own and operate the Rough storage facility and certain related assets in the
United Kingdom to a subsidiary of Centrica plc for approximately $500 million.
The Company repaid the $60 million remaining balance of the related $250
million interim financing with proceeds from the sale.

   Additionally, the capital plan has been enhanced by the Company's decision
to exit third party risk management aspects of the marketing and trading
business and certain other actions that are expected to result in reduced
collateral requirements, which actions are further described below.

   The remaining elements of the capital plan are subject to a number of risks,
including market conditions for asset sales, the timeliness and ability to
obtain required regulatory approvals for asset sales and the negative effects
of Dynegy's current financial condition, weak operating results and ongoing
investigations and litigation. Dynegy currently does not expect to pursue in
the near term the previously announced initial public offering of Dynegy Energy
Partners L.P. Dynegy cannot guarantee that any of the remaining transactions
will be successfully completed or that, if completed, they will occur on terms
that the Company currently anticipates.

Available Credit Capacity, Liquidity and Debt Maturities

   Sources of Liquidity.  Dynegy's liquidity position has improved since the
filing of its second quarter 2002 Form 10-Q, primarily from the cash proceeds
received from the sale of Northern Natural in August 2002 and the sale of its
United Kingdom natural gas storage assets in September 2002 and November 2002.
Dynegy has relied on these cash proceeds, together with cash proceeds from the
other capital plan initiatives described above, cash from operations and
limited borrowings available under its revolving credit facilities, to satisfy
its capital requirements. Given its current non-investment grade credit
ratings, the ongoing re-audit of its 1999-2001 financial statements and its
limited access to the capital markets, Dynegy expects to continue to rely
primarily on cash on hand, cash from operations and proceeds from its capital
plan initiatives to fund its near-term obligations.

   The following table summarizes Dynegy's consolidated credit capacity and
liquidity position at September 30, 2002 ($ in millions):

   Uses of Liquidity and Current Liquidity Position.  During the third quarter
2002, significant uses of liquidity included the following:

  .   Retirement of $200 million in DHI senior notes which matured on July 15,
      2002.

  .   Funding of a $19 million quarterly payment under the restructured Black
      Thunder financing.

  .   Funding of a $17 million payment under the ABG Gas Supply financing.

  .   Issuance of approximately $455 million of cash collateral and letters of
      credit relating to the Company's marketing and trading business and other
      commercial obligations.

   Since September 30, 2002, Dynegy has repaid the $250 million interim
financing relating to the sale of the UK storage facilities and the $19 million
fourth quarter payment under the Black Thunder financing.

   After giving effect to the Rough sale and the repayment of the $250 million
interim financing, together with the above-described uses of liquidity, the
Company's total available liquidity as of November 14, 2002 was approximately
$1,307 million, including approximately $784 million in cash, $129 million in
available borrowing capacity and $394 million in highly liquid inventory.

   Debt Maturities.  As of November 14, 2002, the Company's debt maturities and
related obligations through December 31, 2003 were approximately as follows:

   As indicated above, Dynegy has significant revolver maturities in the second
quarter 2003. Dynegy has begun discussions with its lenders with respect to the
refinancing of all or a portion of these revolving credit facilities. If Dynegy
is successful in entering into one or more new revolving credit facilities, it
expects such facilities would likely be smaller and would have higher pricing
and more restrictive terms than the current facilities. However, the Company
and its lenders may be unable to reach mutually agreeable terms for one or more
new revolving credit facilities. Dynegy faces significant risks relating to the
satisfaction or refinancing of the obligations under these facilities. Please
read "Conclusion" below for discussion of Dynegy's plans with respect to these
obligations and the covenant compliance and other execution risks inherent
therein.

Financing Trigger Events

   Dynegy's debt instruments and other financial obligations include routine
provisions, which, if not met, could require early payment, additional
collateral support or similar actions. For Dynegy, these trigger events include
leverage ratios, insolvency events, defaults on scheduled principal or interest
payments, acceleration of other financial obligations and change of control
provisions. Dynegy does not currently have any trigger events tied to specified
credit ratings or stock price in its debt instruments and has not executed any
transactions that require it to issue equity based on credit rating or other
trigger events. Please read "Conclusion" for a discussion of the Company's
compliance with other covenants contained in its debt instruments.

Collateral Obligations

   As a result of Dynegy's non-investment grade credit ratings and
counterparties' reduced confidence in its ability to satisfy its obligations,
the Company has received numerous requests from counterparties to provide
collateral support for its marketing and trading and other commercial
obligations, including obligations to support DMS. These requests generally are
made under the Uniform Commercial Code, which allows for demands of adequate
assurance of performance when reasonable grounds for insecurity exist, or
contracts containing "adequate assurance" provisions or specific ratings
triggers that address collateral posting requirements. Specific ratings
triggers generally give counterparties the right to request collateral or, if
collateral is not provided, suspend or terminate credit if the Company's credit
ratings fall below investment grade; "adequate assurance" provisions permit a
counterparty to request adequate assurance (which is generally not specified in
the agreement) of continued performance. In most instances, Dynegy has
responded by posting cash or letters of credit to collateralize substantially
all of its marketing and trading obligations and a large portion of its other
commercial obligations. Outstanding letters of credit and cash collateral
totaled approximately $1.3 billion as of November 13, 2002.

   The obligations against which Dynegy has posted collateral include those
relating to certain of its long-term tolling agreements and other related
contracts. The Company is working with various counterparties to determine and
provide mutually acceptable collateral or other adequate assurance under these
contracts. The Company has yet to reach agreement with Sithe/Independence
Funding and Quachita Power LLC regarding a mutually acceptable amount of
collateral. Although the Company is current on all payments, it has received a
notice of default from each of these counterparties with regard to collateral
assurance and is continuing to negotiate these issues. The Company's annual net
payments under the Sithe/Independence and Quachita Power arrangements
approximate $66 million and $55 million, respectively, and the contracts extend
through 2014 and 2012, respectively.

   In response to the ongoing reductions in the liquidity of the trading
markets and the actions of counterparties either requiring additional
collateral or refusing to trade with the Company, Dynegy continued to scale
back the level of its customer and risk-management business activities during
the third quarter 2002. On October 16,

           For the Interim Periods Ended September 30, 2002 and 2001

2002, Dynegy Inc. announced its decision to exit third party risk management
aspects of the marketing and trading business. This announcement has no impact
on the commercial activities of Dynegy's power generation or midstream
businesses. The power generation business will continue to manage commodity
price risk existing in its physical asset positions through optimizing fuel
procurement and the marketing of power from these assets. Further, the
midstream business will continue to manage commodity price risk associated with
its operations related to fuel procurement and the marketing of natural gas and
natural gas liquids in the markets where it operates.

   In connection with the Company's decision to exit third party risk
management aspects of the marketing and trading business, it subsequently
announced that it entered into a letter of intent to sell a significant portion
of its Canadian natural gas business to The Seminole Group, Inc. Dynegy also
agreed to sell to Seminole its 50 percent ownership in Tidal Energy Marketing,
Inc., a wholesale crude oil marketing company. The transactions, which are
subject to the negotiation and execution of definitive documentation,
regulatory approval and other customary conditions, are expected to close in
November 2002.

   The Company's decision to exit third party risk management aspects of the
marketing and trading business is expected to reduce significantly its
collateral requirements and overall corporate expenses.

Credit Rating Discussion

   Credit ratings impact the Company's ability to obtain short- and long-term
financing, the cost of such financing and the execution of its commercial
strategies. In determining the Company's credit ratings, the rating agencies
consider a number of factors. Quantitative factors that management believes are
given significant weight include, among other things, EBITDA; operating cash
flow; total debt outstanding; off balance sheet obligations and other
commitments; fixed charges such as interest expense, rent or lease payments;
payments to preferred stockholders; liquidity needs and availability; and
various ratios calculated from these factors. Qualitative factors include,
among other things, predictability of cash flows, business strategy, industry
position, litigation, regulatory investigations and other contingencies.
Although these factors are among those considered by the rating agencies, each
agency may calculate and weigh each factor differently.

   Since the Company filed its second quarter 2002 Form 10-Q on August 14,
2002, Moody's Investors Service again lowered its ratings on Dynegy. The senior
unsecured debt ratings were lowered from "B1" to "B3" by Moody's who has
indicated that the ratings outlook for all of Dynegy's ratings remained
negative. Moody's stated that this ratings actions was based on continuing
concerns due to, among other things, increased amounts of secured debt and the
expectation that future renewals of existing bank debt will likely be done on a
secured basis, effectively subordinating the Company's senior unsecured lenders.

   As of November 13, 2002, Dynegy's credit ratings were as set forth in the
table below. All three major credit rating agencies maintained a negative
outlook with respect to their ratings.

Series B preferred stock provide that all of the outstanding shares of the

are restrictions under applicable state law that prevent the Company from
redeeming the preferred stock if it would render the Company insolvent. If such
redemption is restricted under applicable law, the Company believes that the
redemption obligation will remain outstanding until such time as the law would
permit such redemption and such redemption obligation is satisfied. The failure
to redeem the Series B preferred stock on the redemption date as described
above is not an event of default under any of the Company's bank borrowings,
secured debt, senior notes or other debt obligations. The shares of Series B
preferred stock are not entitled to a dividend in cash or in kind or Board
representation either before or after the redemption date.

Capital Leases

   In response to the initiatives currently underway at the FASB, on June 28,
2002 the Company unilaterally undertook certain actions, the effect of which
altered the accounting for some of its existing lease obligations and
anticipated lease obligations relating to assets under construction. These
actions included the delivery of Dynegy guarantees of lessor debt in certain
existing leases of power generation facilities. In addition, the Company
notified certain lenders of its intent to purchase power generation facilities
that are currently under construction and that were expected to be placed in
synthetic leases upon completion of their construction. As a result of these
actions, approximately $525 million of obligations due in 2005 to 2007 were
brought on-balance sheet. This non-cash action resulted in an increase to
Property, Plant and Equipment and a corresponding increase in Long-Term Debt on
the Company's Condensed Consolidated Balance Sheet. These obligations were
previously reported as lease obligations in the footnotes to the Company's
financial statements and in the Commercial Financial Obligations and Contingent
Financial Commitments tables in the Annual Report on Form 10-K for the period
ending December 31, 2001 (the "Form 10-K"). In addition, actions taken by the
Company relating to assets under construction required the reclassification of
approximately $673 million from Prepayments and Other Assets to Property, Plant
and Equipment on the Company's Condensed Consolidated Balance Sheet.

Capital Expenditures

   Capital spending for the three- and nine-month periods ended September 30,
2002 totaled $74 million and $539 million, respectively, and related primarily
to the WEN segment. For the anticipated future, the Company intends to limit
its capital expenditures primarily to required maintenance capital
expenditures. The Company expects that its required maintenance capital
expenditures will total approximately $38 million for the fourth quarter 2002
and approximately $151 million for the entirety of 2003.

Conclusion

   Dynegy believes its current liquidity position should be sufficient to
permit the Company to meet its debt maturities and other obligations through
the first quarter 2003. The sufficiency of the Company's liquidity will depend
upon:

  .   Dynegy's continued compliance with the covenants in its bank credit and
      other debt facilities or its ability to negotiate waivers in the event of
      a covenant default;

  .   Dynegy's ability to repay or refinance the revolvers which mature in the
      second quarter 2003;

  .   Dynegy's ability to manage its exit from third party customer risk
      management aspects of the marketing and trading business and the timing
      of the expected cash flows and reduction in collateral from this exit;

  .   the level of earnings and cash flow from Dynegy's assets and businesses,
      which is subject to the effect of changes in commodity prices,
      particularly natural gas and power;

  .   Dynegy's non-investment grade credit ratings, the effect of these ratings
      on Dynegy's ability to access capital markets and to conduct normal
      commercial operations and the effect of any further downgrade in its
      credit ratings on refinancings;

  .   ongoing investigations and litigation relating to Project Alpha, Dynegy's
      trading practices and its activities in the California power markets; and

  .   confidence in Dynegy's financial reporting in light of the previously
      announced restatements and the ongoing re-audit of its 1999-2001
      financial statements.

   Dynegy's liquidity may be significantly adversely affected if it is unable
to refinance the credit facilities that mature in the second quarter 2003.
Dynegy also faces the risk of a covenant default on these facilities or other
debt instruments prior to maturity. The bank facilities contain various
covenants, which include EBITDA-to-interest and debt-to-capitalization
financial covenants. The Company was in compliance with the covenants in its
credit facilities and other debt instruments at September 30, 2002. While many
of the charges incurred by the Company during 2002 are excluded from the
compliance calculations, continued weakness in the Company's operating results
compared with results in 2001 will make it more difficult for the Company to
continue to comply with certain of its financial covenants. Compliance with
these financial covenants is measured on a quarterly basis.

   Any failure to satisfy one or more of its financial covenants would
constitute a breach giving rise to a default under the applicable debt
instrument and would permit the lenders under such debt instrument to
accelerate the maturity of Dynegy's outstanding obligations thereunder.
Depending upon the particular debt instrument, such a breach or any action by
the lenders to accelerate the maturity of amounts owing would result in a
default under or trigger cross-acceleration provisions in a significant portion
of the Company's other outstanding debt instruments. Consequently, in the event
of non-compliance, Dynegy may repay these facilities, seek waivers or
amendments from the lenders under these facilities or attempt to refinance
these facilities prior to their scheduled maturity. The Company cannot provide
any assurance that it could repay, obtain waivers or amendments with respect to
or refinance these facilities in the event of any such default.

   Dynegy has executed on the principal elements of its capital plan in order
to meet its current obligations as they mature and provide the necessary
collateral to support its commercial operations. Dynegy believes that the
combination of its liquidity initiatives and the roll off of collateral and
cash flow from its exit of marketing and trading should enable the Company to
retrieve all or a sufficient portion of its second quarter 2003 maturities.
However, the Company faces significant risks related to its ongoing operations
and other matters discussed above. Dynegy also faces the risk that it may not
be able to reach agreement with its lenders on mutually acceptable terms. If
Dynegy fails to execute the remaining elements of its strategy, it may be
forced to consider other strategic alternatives including a possible
reorganization under the protection of federal bankruptcy laws.

                       RECENT ACCOUNTING PRONOUNCEMENTS

   See Note 2 to the accompanying financial statements for a discussion of
recently issued accounting pronouncements affecting the Company. Specifically,
Dynegy adopted the net presentation provisions of Emerging Issues Task Force
Issue No. 02-3 in the third quarter 2002. Please see Note 2 for the impact such
adoption had on the Company's Condensed Consolidated Statements of Operations.

                            ACCOUNTING METHODOLOGY

   The Company has identified three critical accounting policies that require a
significant amount of judgment and are considered to be the most important to
the portrayal of Dynegy's financial position and results of operations: the
accounting for long-lived assets, the evaluation of counterparty credit and
other similar risks and revenue recognition. See Note 3 to the financial
statements included in the Form 10-K for a discussion of the process
surrounding the evaluation of counterparty credit and other similar risks. For
disclosure on the Company's accounting for long-lived assets and revenue
recognition, refer to Note 2 to the financial statements included in the Form
10-K. Accounting methodology and application of accounting methodologies are
more fully described in the Form 10-K.

             ENTERPRISE RISK MANAGEMENT, VALUATION AND MONITORING

   Market Risk.  The Company is exposed to commodity price risk related to its
natural gas, NGLs, electricity and coal businesses. In addition, fuel
requirements at its power generation, gas processing and fractionation
facilities represent additional commodity price risks to the Company. In order
to manage these commodity price risks, Dynegy has routinely utilized certain
types of fixed-price forward purchase and sales contracts, futures and option
contracts traded on the New York Mercantile Exchange and swaps and options
traded in the over-the-counter financial markets to:

  .   Manage and hedge its fixed-price purchase and sales commitments;

  .   Provide fixed-price commitments as a service to its customers and
      suppliers;

  .   Reduce its exposure to the volatility of cash market prices;

  .   Protect its investment in storage inventories; and

  .   Hedge fuel requirements.

   The potential for changes in the market value of Dynegy's commodity,
interest rate and currency portfolios is referred to as "market risk." A
description of each market risk category is set forth below:

  .   Commodity price risks result from exposures to changes in spot rates,
      forward prices and volatilities in commodities, such as electricity,
      natural gas, coal, NGLs, and other similar products;

  .   Interest rate risks primarily result from exposures to changes in the
      level, slope and curvature of the yield curve and the volatility of
      interest rates; and

  .   Currency rate risks result from exposures to changes in spot rates,
      forward rates and volatilities in currency rates.

   Dynegy seeks to manage these market risks through diversification,
controlling position sizes and executing hedging strategies. The ability to
manage an exposure may, however, be limited by adverse changes in market
liquidity or other factors.

   In October 2002, Dynegy Inc. announced it would exit aspects of the
marketing and trading business relating to third party or customer risk
management for natural gas and power. The decision to exit the third party risk
management aspects of this business is expected to reduce significantly the
Company's collateral requirements and overall corporate expenses. The Company
expects to complete a significant portion of the exit from this business over
the next three to six months. The Company will maintain the resources and make
the necessary arrangements to meet its customer commitments, including
retaining personnel and risk management capabilities. This announcement has no
impact on the commercial activities of Dynegy's midstream and generation
businesses. The midstream business will continue to manage commodity price risk
associated with its

                                      47

operations related to fuel procurement and the marketing of natural gas and
natural gas liquids in the markets in which it operates. Further, the
generation business will continue to manage commodity price risk existing in
its physical asset positions through optimizing fuel procurement and the
marketing of power from these assets.

   Valuation Criteria and Management Estimates.  As more fully described in the
Form 10-K, Dynegy utilizes a fair value accounting model for certain aspects of
its operations as required by generally accepted accounting principles. The net
gains or losses resulting from the revaluation of these contracts during the
period are recognized currently in the Company's results of operations. For
financial reporting purposes, assets and liabilities associated with these
transactions are reflected on the Company's balance sheet as risk management
assets and liabilities, classified as short- or long-term pursuant to each
contract's individual tenor. Net unrealized gains and losses from these
contracts are classified as revenue in the accompanying statement of
operations. As a result of EITF 02-3 the Company recorded, realized and settled
amounts net in the income statement and have been restated as such for prior
periods herein.

   Dynegy has historically estimated the fair value of its marketing portfolio
using a liquidation value approach assuming normal liquidity. The estimated
fair value of the portfolio is computed by multiplying all existing positions
in the portfolio by estimated mid-market prices, reduced by a LIBOR-based time
value of money adjustment and deduction of reserves for credit, price and
market risks. Current market conditions coupled with Dynegy's stated intent to
exit aspects of the marketing and trading business relating to third party or
customer risk management for natural gas and power changes the assumptions used
by the Company in extracting the realizability of its portfolio. (See
discussion in Results of Operations below.)

   Dynegy's forward power price curves are derived by modeling a combined cycle
gas facility as a "spark spread" option in the calculation of required cost of
capital returns. A spark spread option represents the implied value
relationship between natural gas as a fuel for the combined cycle gas facility
and the conversion value of the power generated by the facility. This price
curve assumption is based on the premise that a portfolio manager would be
indifferent to holding these two assets (the spark spread option or the
generation facility) and is reflective of how Dynegy manages its own portfolio
of physical and financial positions. Dynegy's modeling methodology has been
consistently applied during 2002 and the three years ended December 31, 2001.
Dynegy's proprietary models compute forward prices over a time horizon based on
the following set of inputs:

 Monthly On and Off Peak Curve Shapes  Local Taxes and Environmental Restriction
   Regional Correlation Assessments            Industry Cost of Capital
        Supply/Demand Balance
</TABLE>

   Dynegy's cost-based pricing models depend on extensive, region specific
studies regarding the cost of new generation, as well as detailed proprietary
competitive intelligence on new generation additions, retirements and estimates
of regional power demand growth. Dynegy believes its pricing models are based
on reasonable and sound assumptions. Risks associated with these assumptions
include actual versus estimated regional supply/demand balance, the accuracy of
cost and cost of capital estimates and assumptions regarding the preferred
future technologies and regulatory factors that could impact the continued
formation of competitive markets. As with pricing curves derived from quoted
market prices, the application of forecasted pricing curves to contractual
commitments may result in realized cash returns on these commitments that vary
significantly, either positively or negatively, from the estimated values.

   Dynegy's enterprise-wide risk department, led by Dynegy's Chief Risk
Officer, independently verifies the outputs from the Company's proprietary
pricing models. This department routinely applies a mathematical model approach
to independently assess forward price curves. This methodology derives forward
energy prices from assumptions about the random factors driving energy prices
and other key variables such as the long-term price and mean reversion rate.
This method is consistent with market observable forward prices and
volatilities. The method models the evolution of the entire forward curve
conditioned on the initial forward curve. Material differences, if any, between
the forward curves developed from Dynegy's proprietary systems and the
mathematical model are reviewed, assessed and, if deemed necessary by the Chief
Risk Officer and Controller, adjusted in determining the reported fair value of
the marketing portfolio.

   Risk-Management Asset and Liability Disclosures.  The following tables

    position after deduction of time value, credit, price and other reserves
    necessary to determine fair value. These amounts exclude the fair value
    associated with certain derivative instruments designated as hedges. The
    net risk-management assets at September 30 of $690 million on the Condensed
    Consolidated Balance Sheet include the $658 million herein as well as
    emission allowance credits, hedging instruments and other non-trading
    amounts.

    2001 row.

   The increases (decreases) in the Net Risk-Management Asset and Liabilities
were impacted by the following:

  .   The recognition of a $223 million liquidity reserve in the third quarter
      2002 that impairs the mark-to-market value of the Company's marketing and
      trading portfolio at September 30, 2002. The recognition of an
      incremental liquidity reserve in determining estimated fair value
      reflects a substantial reduction during the quarter in market transaction
      volumes, principally in the U.S. power marketing and trading business and
      recognizes the negative estimated impact on the realizability of the net
      asset value of the portfolio;

  .   The realization of approximately $442 million of cash related to
      contracts settled during the first three quarters of 2002;

  .   A net deferral of the anticipated timing of cash inflows totaling $95
      million from the 2002 through 2004 time periods to beyond 2006 related to
      long-term natural gas storage transactions. The change in the timing of
      cash inflows on these transactions resulted from the decision to extend
      the term of the contract through 2007;

  .   The execution in the first quarter of 2002 of a large power origination
      transaction, which increased anticipated cash inflows beyond 2006 by $114
      million; and

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
           For the Interim Periods Ended September 30, 2002 and 2001

--------
(1) This amount includes approximately $140 million which represents
    management's estimate of the initial value of new contracts entered into in
    the nine months ended September 30, 2002.
(2) This amount includes a $223 million liquidity reserve discussed more fully
    in Note 5 to the accompanying Condensed Consolidated Financial Statements.
(3) This amount includes cash settlements of hedging instruments and other
    non-trading amounts in addition to the cash settlement of commodity
    contracts.
(4) Dynegy's modeling methodology has been consistently applied period over
    period.
(5) This amount consists primarily of changes in value of foreign currency and
    interest rate hedges.
(6) This amount consists primarily of changes in value of interest rate hedges.
(7) This amount consists primarily of the customer and risk-management portion
    of WEN's operating income before the deduction of Depreciation and
    Amortization, Impairment and Other Charges and General and Administrative
    Expenses.
(8) This amount represents cash received for sales of emission credits, cash
    received associated with the settlement of fuel hedges and cash payments
    associated with foreign currency hedges.
(9) This amount is calculated as "Cash received during the period" less "Net
    recognized operating loss."

   The following table provides an assessment of net contract values by year
based on the Company's valuation methodology described above. Approximately 62
percent of Dynegy's net risk-management asset value at September 30, 2002 was
determined by market quotations or validation against industry posted prices.
This is a significant reduction from the December 31, 2001 amount of 92
percent. The percentage reduction resulted from a significant realization of
cash during the nine-month period, a significant power origination transaction
during the first quarter, the impact of reduced industry liquidity on the
portfolio and a transfer of $105 million of cash flows from Other External
Sources to Prices Based on Models during the second quarter 2002. As a result
of reduced industry liquidity, the Company recognized a pre-tax charge of $223
million to impair the mark-to-market value of the marketing and trading
portfolio. The Company will continue to assess the liquidity of the market, as
a prolonged downturn in transaction volumes in the industry as a whole or
within specific regions could result in further reduction in the availability
of market quotations.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
           For the Interim Periods Ended September 30, 2002 and 2001

   Value at Risk ("VaR").  In addition to applying business judgment, senior
management uses a number of quantitative tools to manage the Company's exposure
to market risk. These tools include:

  .   Risk limits based on a summary measure of market risk exposure, referred
      to as VaR; and

  .   Stress and scenario analyses performed daily that measure the potential
      effects of various market events, including substantial swings in
      volatility factors, absolute commodity price changes and the impact of
      interest rate and foreign exchange rate movements.

   The modeling of the risk characteristics of Dynegy's marketing portfolio
involves a number of assumptions and approximations. Dynegy estimates VaR using
a JP Morgan RiskMetrics(TM) approach assuming a one-day holding period. Inputs
for the VaR calculation are prices, positions, instrument valuations and a
variance-covariance matrix. While management believes that these assumptions
and approximations are reasonable, there is no uniform industry methodology for
estimating VaR, and different assumptions and/or approximations could produce
materially different VaR estimates.

   Dynegy uses historical data to estimate the Company's VaR and, to better
reflect current asset and liability volatilities, these historical data are
weighted to give greater importance to more recent observations. Given its
reliance on historical data, VaR is effective in estimating risk exposures in
markets in which there are not sudden fundamental changes or shifts in market
conditions. An inherent limitation of VaR is that past changes in market risk
factors, even when weighted toward more recent observations, may not produce
accurate predictions of future market risk. VaR should be evaluated in light of
this and the methodology's other limitations.

   VaR represents the potential loss in value of Dynegy's enterprise-wide
marketing portfolio due to adverse market movements over a defined time horizon
within a specified confidence level. For the VaR numbers reported below, a
one-day time horizon and a 95% confidence level were used. This means that
there is a one in 20 statistical chance that the daily portfolio value will
fall below the expected maximum potential reduction in portfolio value at least
as large as the reported VaR. Thus, a change in portfolio value greater than
the expected change in portfolio value on a single trading day would be
anticipated to occur, on average, about once a month. Gains or losses on a
single day can exceed reported VaR by significant amounts. Gains or losses can
also accumulate over a longer time horizon such as a number of consecutive
trading days.

   In addition, Dynegy has provided its VaR using a one-day time horizon and a
99% confidence level. The purpose of this disclosure is to provide an
indication of earnings volatility using a higher confidence level. Under this
presentation, there is one in 100 statistical chance that the daily portfolio
value will fall below the expected maximum potential reduction in portfolio
value at least as large as the reported VaR. The Company has also disclosed an
average VaR for the nine-month period ended September 30, 2002 and the year
ended December 31, 2001 in order to provide context around the one-day amounts.

(1) Amounts have not been updated for restatement items discussed in Note 1 to
    the accompanying Condensed Consolidated Financial Statements as such
    amounts cannot be retroactively recalculated.

   The decrease in One Day VaR from December 31, 2001 is due primarily to the
reduction in exposure in the domestic power portfolio. The reduced exposure is
a result of less price volatility and less trading caused by the current market
conditions and the downgrades to Dynegy's credit ratings. The increase in
Average VAR from December 31, 2001 is due primarily to the long-term power
origination transactions executed in the first quarter 2002.

   Credit Risk.  Credit risk represents the loss that the Company would incur
if a counterparty fails to perform under its contractual obligations. To reduce
the Company's credit exposure, the Company seeks to enter into payment netting
agreements with counterparties that permit Dynegy to offset receivables and
payables with such counterparties. Dynegy attempts to further reduce credit
risk with certain counterparties by entering into agreements that enable the
Company to obtain collateral or to terminate or reset the terms of transactions
after specified time periods or upon the occurrence of credit-related events.
The Company may, at times, use credit derivatives or other structures and
techniques to provide for third-party guarantees of the Company's
counterparties' obligations.

   Dynegy's industry has historically operated under negotiated credit lines
for physical delivery contracts. Dynegy's Credit Department, based on
guidelines set by Dynegy's Credit Policy Committee, establishes Dynegy's
counterparty credit limits. For collateralized transactions, the Company also
evaluates potential exposure over a shorter collection period and gives effect
to the value of collateral received. The Company further seeks to measure
credit exposure through the use of scenario analyses and other quantitative
tools. Dynegy's credit management systems monitor current and potential credit
exposure to individual counterparties and on an aggregate basis to
counterparties and their affiliates. Recent events in the merchant energy
industry have affected historical credit activities in the industry. Please
read "Trade Credit and Other Collateral Obligations" above.

   Interest Rate Risk.  Interest rate risk results from variable rate financial
obligations and from providing risk-management services to customers, since
changing interest rates impact the discounted value of future cash flows used
to value risk-management assets and liabilities. Management continually
monitors its exposure to fluctuations in interest rates and may execute swaps
or other financial instruments to hedge and mitigate this exposure.

   The following table sets forth the daily and average VaR associated with the
interest rate component of the marketing portfolio. Dynegy seeks to manage its
interest rate exposure through application of various hedging strategies.
Hedging instruments executed to mitigate such interest rate exposure in the
marketing portfolio are included in the VaR as of September 30, 2002 and
December 31, 2001 and are reflected in the table below.

</TABLE>

   The decrease in One Day VaR is due to the timing of removing positions with
Enron from the Company's portfolio at the end of December 2001 and not changing
the hedge positions until early January 2002. The decrease in Average VaR is
due to the impact of the Company's hedging program since the entire nine months
of 2002 were under this program that was initiated in November 2001.

   In addition to the marketing portfolio, the Company is exposed to
fluctuating interest rates as it relates to other variable rate financial
obligations. Based on sensitivity analysis as of September 30, 2002, it is
estimated that a one percentage point interest rate movement in the average
market interest rates (either higher or (lower)) over the twelve months ended
September 30, 2003 would (decrease) increase income before taxes by
approximately $11 million. Hedging instruments executed to mitigate such
interest rate exposure are included in the sensitivity analysis.

   Foreign Currency Exchange Rate Risk.  Foreign currency risk arises from the
Company's investments in affiliates and subsidiaries owned and operated in
foreign countries. Such risk is also a result of risk management transactions
with customers in countries outside the U.S. Management continually monitors
its exposure to fluctuations in foreign currency exchange rates. When possible,
contracts are denominated in or indexed to the U.S. dollar, or such risk may be
hedged through debt denominated in the foreign currency or through financial
contracts. At September 30, 2002, the Company's primary foreign currency
exchange rate exposures were the United Kingdom Pound, Canadian Dollar and
European Euro.

   The following table sets forth the daily and average foreign currency
exchange VaR. Hedging instruments executed to mitigate such foreign currency
exchange exposure are included in the VaR as of September 30, 2002 and December

                             RESULTS OF OPERATIONS

   On October 16, 2002, Dynegy Inc. announced a restructuring plan designed to
improve operational efficiencies and performance across its lines of business.
The plan provides for the adoption of a decentralized business structure
consisting of a streamlined corporate center and operating units in power
generation and natural gas liquids and regulated energy delivery. Dynegy's
operations are reported in three segments: Wholesale Energy Network ("WEN"),
Dynegy Midstream Services ("DMS") and Transmission and Distribution ("T&D").
Dynegy's T&D segment includes the operations of Northern Natural, which was
sold in August 2002 and is therefore included as a discontinued operation.

   Provided below are a narrative and tabular presentation of certain operating
and financial data and statistics for the Company's businesses for the three-
and nine-month periods ended September 30, 2002 and 2001. The comparative
financial information contained herein has been revised to reflect the known
effects of the restatement items described in Note 1 to the accompanying
Condensed Consolidated Financial Statements. For segment reporting purposes,
all general and administrative expenses incurred by Dynegy on behalf of its
subsidiaries are charged to the applicable subsidiary as incurred. Dynegy
allocates indirect general and administrative expenses to its subsidiaries
using a two-step formula that considers both payroll expense and the net book
value of property, plant and equipment. Interest expense incurred by Dynegy on
behalf of its subsidiaries is allocated based on the subsidiaries' debt to
equity relationship. Other income (expense) items incurred by Dynegy on behalf
of its subsidiaries are allocated equally among sub-components of the four
segments.

   Net income (loss) include the following charges (in millions):

--------
 (1) The Company recognized an after-tax charge of $737 million associated with
     the impairment of goodwill in the WEN segment. There was no tax basis in
     this intangible asset resulting in a pre-tax charge equal to the after-tax
     amount. This third quarter charge is included in Goodwill Impairment in
     the accompanying Condensed Consolidated Statement of Operations.
 (2) The Company recognized an after-tax charge of $145 million ($223 million
     pre-tax) associated with recognition of a liquidity reserve in the third
     quarter 2002 that impairs the mark-to-market value of the Company's
     marketing and trading portfolio at September 30, 2002. The recognition of
     an incremental liquidity reserve in determining estimated fair value
     reflects a substantial reduction during the quarter in market transaction
     volumes, principally in the U.S. power marketing and trading business, and
     recognizes the negative estimated impact on the realizability of the net
     asset value of the portfolio. This charge is included in Revenues in the
     accompanying Condensed Consolidated Statement of Operations.

           For the Interim Periods Ended September 30, 2002 and 2001

 (3) The Company recognized an after-tax charge of approximately $62 million
     for the impairment of certain investments in generation assets in the
     third quarter 2002. The charge is included in Earnings (Losses) From
     Unconsolidated Investments in the accompanying Condensed Consolidated
     Statement of Operations.
(4) Dynegy incurred an after-tax loss of $60 million ($62 million pre-tax) on
    the sale of Northern Natural to MidAmerican during the third quarter 2002.
    (See Note 4 to the accompanying financial statements.) This loss is
    included in Discontinued Operations in the accompanying Condensed
    Consolidated Statement of Operations.
(5) The Company recognized an after-tax charge of approximately $5 million ($8
    million pre-tax) for the impairment of technology investments in the third
    quarter 2002. For the nine-month period ended September 30, 2002, the
    Company recognized a cumulative after-tax charge of approximately $22
    million ($34 million pre-tax) for the impairment of technology investments.
    These charges are included in Earnings (Losses) from Investments in
    Unconsolidated Investments in the accompanying Condensed Consolidated
    Statement of Operations.
(6) The Company recognized an after-tax charge of approximately $21 million
    ($32 million pre-tax) for severance benefits for approximately 309
    employees, including the Company's former Chief Executive Officer and Chief
    Financial Officer in the second quarter. $18 million ($28 million pre-tax)
    is included in Impairment and Other Charges in the accompanying Condensed
    Consolidated Statement of Operations. The additional severance charge of $3
    million after-tax ($4 million pre-tax) was allocated to Northern Natural,
    which is included in Discontinued Operations.
(7) The amount represents $4 million after-tax ($6 million pre-tax) of fees
    related to a voluntary action that the Company took in the second quarter
    2002 that altered the accounting for certain lease obligations.
    Additionally, the Company had $4 million after-tax ($6 million pre-tax) of
    write-offs in the second quarter 2002 related to information technology
    equipment. In the third quarter 2002, in conjunction with the Company's
    decision to exit certain aspects of the marketing and trading business
    relating to third party or customer risk management for natural gas and
    power, the Company's investment in Dynegydirect was written off. This
    resulted in an after-tax charge of $19 million ($29 million pre-tax). These
    amounts are included in Other Expenses in the accompanying Condensed
    Consolidated Statement of Operations.

Three-Month Periods Ended September 30, 2002 and 2001

   For the quarter ended September 30, 2002, Dynegy recorded a net loss of
$1,068 million, compared with third quarter 2001 net income of $261 million.
Charges recognized in the third quarter 2002, as more fully described in the
footnotes to the table above, included after-tax charges for a $737 million
goodwill impairment, a $145 million liquidity reserve, a $62 million impairment
of generation investments, a $60 million loss on the sale of Northern Natural,
a $19 million after-tax charge related to the write-off of Dynegydirect, and a
$5 million after-tax impairment of technology investments. There were no such
adjustments during the third quarter 2001.

   Dynegy Inc. announced in early October 2002 an organizational restructuring
and its intent to exit third party risk management aspects of the marketing and
trading business. Dynegy Inc. also announced a work force reduction affecting
approximately 780 employees. The Company estimates that it will recognize
pre-tax charges associated with severance of $38 million ($25 million
after-tax) in the fourth quarter 2002 and $5 million ($3 million after-tax) in
the first quarter 2003.

   Operating income decreased approximately $1,405 million quarter-to-quarter
due primarily to the negative impact of the goodwill impairment and the
liquidity reserve, as well as reduced margins from operating units. Operating
income also reflects increased depreciation and amortization expense associated
with the expansion of

Dynegy's depreciable asset base. General and administrative expenses were lower
period-to-period principally as a result of significantly lower variable
compensation costs in the 2002 period, which were partially offset by higher
legal and audit fees.

   Dynegy's losses from unconsolidated investments were approximately $39
million in the 2002 period compared to earnings of $96 million in 2001.
Variances period-to-period in these results primarily reflect the impact of the
$62 million impairment of generation investments, the $8 million impairment of
technology investments and a $75 million decrease in earnings related to West
Coast Power due to lower in delivered volumes.

   Interest expense totaled $71 million for the three-month period ended
September 30, 2002, compared to $33 million for the 2001 period. The variance
is primarily attributable to higher average principal balances in the 2002
period compared to the 2001 period partially offset by lower average interest
rates on borrowings.

   Other income and expenses, net (including minority interest expense and
accumulated distributions associated with trust preferred securities) totaled
$36 million in expense in the quarter ended September 30, 2002. Combined other
income and other expenses totaled $24 million in expense in 2001. The 2002
quarter includes the $29 million pre-tax write-down of Dynegydirect.

   The Company reported an income tax benefit of $155 million for the quarter
ended September 30, 2002, compared to an income tax provision of $155 million
for the 2001 period. The effective tax rates approximated 13 percent and 37
percent in 2002 and 2001, respectively. The 2002 tax provision was reduced from
statutory rates as a result of book-tax basis differences (principally
impacting the goodwill impairment), the effect of foreign equity investments,
the amortization of intangibles, state income taxes and valuation allowances
recognized in the period relative to the realizability of certain capital loss
carryforwards arising from the sale of Northern Natural and foreign tax credit
carryforwards. The tax provision in the 2001 period varied from the statutory
tax rate of 35 percent principally as a result of book-tax basis differentials
related to the amortization of certain intangibles, other book-tax basis
differences and the effect of foreign equity investments and state income taxes.

Nine-Month Periods Ended September 30, 2002 and 2001

   For the nine months ended September 30, 2002, Dynegy recorded a net loss of
$956 million, compared with net income of $438 million in the same 2001 period.
The nine- month period ended September 30, 2002 included charges related to the
items described above for the three- month period plus the impairment of
technology investments and a severance charge.

   In addition to these charges, 2002 net income decreased period-to-period due
primarily to market events that negatively affected the gas and power marketing
and trading industry in 2002 and the resulting negative impact these events had
on Dynegy's liquidity and creditworthiness, which in turn reduced the
effectiveness and profitability of the Company's marketing and trading,
generation and NGL businesses.

   Operating income decreased $1,511 million period over period primarily due
to the reasons described in the previous paragraph as well as the
aforementioned goodwill charge and liquidity reserve recorded in the third
quarter 2002 and the impairment and other charges taken during the previous two
quarters in 2002 that are more fully described in Note 5 to the accompanying
financial statements.

   Dynegy's earnings (losses) from unconsolidated investments were
approximately $8 million of losses and $186 million of earnings in the 2002 and
2001 periods, respectively. Variances period-to-period in these results

           For the Interim Periods Ended September 30, 2002 and 2001

primarily reflect the impact of the impairment of $62 million of generation
investments, the impairment of $34 million of technology investments resulting
from unfavorable market conditions and a $108 million decrease in earnings
related to West Coast Power due to a decrease in realized prices as well as an
overall decline in demand.

   Interest expense totaled $154 million for the nine-month period ended
September 30, 2002, compared to $96 million for the equivalent 2001 period. The
variance is primarily attributed to higher average principal balances in the
2002 period compared to the 2001 period, partially offset by lower average
interest rates on borrowings.

   Other income and expenses, net (including minority interest expense and
accumulated distributions associated with trust preferred securities) totaled
$50 million in expense in the nine-month period ended September 30, 2002
compared with $48 million in expense in the same 2001 period. Variances
period-to-period in these results primarily reflect losses associated with the
impairment of IT systems in 2002.

   The Company reported an income tax benefit of $114 million for the
nine-month period ended September 30, 2002, compared to an income tax provision
of $270 million for the 2001 period. The effective tax rates approximated 11
percent and 38 percent in 2002 and 2001, respectively. The difference from the
effective tax rates and the statutory tax rate of 35 percent result from the
same factors impacting the third quarter periods.

   Effect of Accounting for Goodwill. As described in Note 2 to the
accompanying financial statements, the Company adopted Statement of Financial
Accounting Standards No. 142, "Goodwill and Other Intangible Assets"
("Statement No. 142"), effective January 1, 2002. Had Statement No. 142 been in
effect in 2001, the Company's net income for the three months ended September
30, 2001 would have been $265 million compared to actual net income reported of
$261 million. For the nine-months ended September 30, 2001, net income would
have been $448 million compared to actual net income reported of $438 million.

Three-Month Periods Ended September 30, 2002 and 2001

   WEN reported a net loss of $1,012 million for the three-month period ended
September 30, 2002, compared with net income of $249 million in the 2001
quarter. The results reflect an overall decline in market liquidity principally
caused by increasing credit concerns in the merchant energy sector,
counterparty concerns over Dynegy's non investment grade credit ratings and a
reduction in the spread between natural gas and power prices. The segment
results generally reflect lower returns from its generation portfolio as a
result of lower power prices and excess generation capacity in the market. As
previously discussed, the segment's operating results include a liquidity
reserve charge in response to current market conditions. The recognition of an
incremental liquidity reserve in determining estimated fair value reflects a
substantial reduction during the quarter in market transaction volumes,
principally in the U.S. power marketing and trading business, and recognizes
the negative estimated impact on the realizability of the net asset value of
the portfolio. Additionally, the Company recognized an after-tax charge of $737
million associated with the impairment of goodwill. There was no tax basis in
this intangible asset resulting in a pre-tax charge equal to the after-tax
amount. The reported earnings were also negatively impacted by the third
quarter 2002 impairment of equity investments and the write-down of
Dynegydirect. Additionally, there was a $75 million decline in earnings from
the equity investment in West Coast Power due to a decrease in delivered
volumes period-over-period. Interest expense was higher in the third quarter
2002 due to higher average borrowings, partially offset by lower average
interest rates.

   Total physical MW hours sold in the third quarter 2002 decreased to 52.3
million MW hours as compared to 125.1 million MW hours in the third quarter
2001. Total natural gas volumes sold in the third quarter 2002 decreased to
11.0 billion cubic feet per day as compared to 12.6 billion cubic feet per day
during last year's third quarter. The decrease in power and gas volumes is due
primarily to the decline in market liquidity resulting from increasing credit
concerns related to Dynegy and in the merchant energy sector generally.

Nine-Month Periods Ended September 30, 2002 and 2001

   WEN reported a net loss of $932 million for the nine-month period ended
September 30, 2002, compared with net income of $393 million in the same 2001
period. Absent the charges discussed above, the decrease in operating results
generally reflect the significant downturn in profitability in the marketing
and trading business period-over-period resulting from credit, liquidity and
market concerns as well as significantly lower price realization in the
generation business in 2002. In addition to the items described above for the
third quarter

comparisons, Dynegy's customer and risk-management business' operating income
for the nine-month period included significant customer origination during the
first quarter 2002 in both the wholesale and commercial and industrial
businesses. The increased origination resulted from new contracts for the
acquisition of long-term power supply at competitive prices and incremental
natural gas storage contracts. The segment's 2002 results include a $109
million decline in earnings from the equity investment in West Coast Power due
to a decrease in realized power prices period-over-period as well as an overall
decline in demand and impairment of technology investments. The results also
include an allocated charge of $19 million associated with severance and
related costs recorded in the second quarter 2002.

   Total physical MW hours sold in the nine-month period ended September 30,
2002 increased to 379.7 million MW hours compared to 282.0 million MW hours in
the same period in 2001 due primarily to increased physical MW hours sold in
Europe and greater customer origination in the first quarter of 2002. Total
natural gas volumes sold in the nine months ended September 30, 2002 increased
to 13.2 billion cubic feet per day as compared to 12.4 billion cubic feet per
day during the same period last year due to the inclusion of incremental
ChevronTexaco volumes associated with former Texaco equity production and
increases in gas volumes sold in Europe.

WEN Outlook

   The weak power price environment has continued into the fourth quarter 2002.
Increased collateralization requirements resulting from credit concerns have
also continued, resulting in higher interest expense and other capital costs in
order to satisfy counterparties' credit concerns. Going forward, Dynegy expects
that its managed exit from third party risk management aspects of the marketing
and trading business will significantly reduce this segment's collateral
requirements and general and administrative expenses. During this period, which
the Company expects will take up to six months, Dynegy will make appropriate
arrangements regarding its long-term contractual obligations, including
retaining personnel and risk-management capabilities and continuing capacity to
support its customers. The Company's ability to successfully manage this exit,
which is dependent on a number of factors, some of which are outside of the
Company's control, will effect the amount of cash that is ultimately realized
from its marketing and trading portfolio.

   Following the exit from third party risk management aspects of the marketing
and trading business, Dynegy's WEN segment will consist primarily of its
generation assets (as well as any remaining risk management positions that
remain, pending a roll-off over the contract term). The results of operations
for Dynegy's generation assets will reflect a sensitivity to natural gas and
power prices as well as terms of contracts for contracted generation. The
Company expects that this business will continue its efforts to manage this
price risk through the optimization of fuel procurement and the marketing of
power generated from its owned and controlled assets. Dynegy's sensitivity to
prices and its ability to manage this sensitivity, however, is subject to a
number of factors, including general market liquidity, Dynegy's liquidity
position and the willingness of counterparties to transact business with Dynegy
given its non-investment grade credit ratings. Other factors that could affect
the prices at which transactions can be consummated and this segment's results
of operations include governmental actions or excess generation capacity in the
markets it serves.

Three-Month Periods Ended September 30, 2002 and 2001

   DMS reported net income of $4 million in the third quarter 2002 compared
with net income of $12 million in the third quarter 2001. The segment's results
of operations during the third quarter 2002 were impacted by lower
fractionation spreads and lower realized prices as compared to higher
fractionation spreads and higher realized prices during the third quarter 2001
as a result of the Company's hedging program and forward selling products at a
higher price than the prevailing market price during such quarter. In addition,
as a result of slow economic recovery, high industry-wide inventory levels,
reduced NGL liquidity and Dynegy specific credit limitations, the segment
experienced a decline in domestic and foreign marketing volumes and margins.
DMS' quarterly results were negatively impacted by $4 million, net of tax, due
to allocated charges related to the impairment of technology investments as
more fully discussed in Note 5 to the Condensed Consolidated Financial
Statements. There were no such charges recorded in the third quarter 2001.

   Aggregate domestic NGL processing volumes totaled 91.6 thousand gross
barrels per day in the third quarter 2002 compared to 82.4 thousand gross
barrels per day during the same period in 2001. A small

percentage of this volume increase resulted from the inclusion of incremental
ChevronTexaco volumes associated with former Texaco equity production. The
majority of the volume growth is related to the Louisiana straddle plants and
is the direct result of an increasing need to process Gulf of Mexico natural
gas production to meet third party pipeline dew point specification limits.

   The average fractionation spread was $1.40 for the three months ended
September 30, 2002, compared to $1.51 for the comparable 2001 period.
Traditional keep-whole processing is only marginally economical at this level.
Historically, the Louisiana straddle plants would not have operated in this
pricing environment.

Nine-Month Periods Ended September 30, 2002 and 2001

   DMS reported net income of $13 million in the nine months ended September
30, 2002 compared with net income of $45 million in the nine months ended
September 30, 2001. In addition to the items described above for the second
quarter comparisons, warmer winter temperatures influenced results of
operations period-to-period. DMS' results for the nine-months ended September
30, 2002 were negatively impacted by $8 million, net of tax, due to allocated
charges related to severance costs and the impairment of technology investments
as more fully discussed in Note 5 to the Condensed Consolidated Financial
Statements. There were no such charges recorded in the nine-month period in
2001.

   Aggregate domestic NGL volumes from processing totaled 91.5 thousand gross
barrels per day in the nine months ended September 30, 2002 compared to 81.5
thousand gross barrels per day during the same period in 2001. A small
percentage of this volume resulted from the inclusion of incremental
ChevronTexaco volumes associated with former Texaco equity production. The
majority of the volume growth related to the Company's Louisiana straddle
plants and is the direct result of an increasing need to process Gulf of Mexico
natural gas production to meet third party pipeline dew point specification
limits.

   The average fractionation spread was $1.24 for the nine months ended
September 30, 2002, compared to $0.80 for the comparable 2001 period. Despite
the year-over-year increase in this spread, traditional keep-whole processing
is only marginally economical at this level. Historically, the Louisiana
straddle plants would not have operated in this pricing environment.

DMS Outlook

   The weak fractionation spread environment has continued into the fourth
quarter 2002. Increased collateralization requirements resulting from credit
concerns have also continued, particularly with respect to the global liquids
business. The Company is exploring alternatives for the global liquids business
to reduce its collateral commitments or to otherwise align it with Dynegy's
current liquidity position, which may include a sale. Going forward, Dynegy
expects that its DMS segment will incur higher interest expenses and other
capital costs in order to satisfy counterparties' credit concerns. Credit
concerns have also made it more difficult for DMS to execute new long-term
commercial agreements or to renew expiring commercial agreements in the
ordinary course of business, potentially resulting in reduced results of
operation.

   DMS' sensitivity to commodity prices can be expected to continue and is
impacted by a number of factors, including:

  .   The correlation between the price of crude oil and NGLs;

  .   The absolute price of natural gas;

                                      65

                           AND RESULTS OF OPERATIONS
           For the Interim Periods Ended September 30, 2002 and 2001


  .   The spread between the price of natural gas and the price of NGLs;

  .   The relative impact of all of these factors based on DMS' mix of
      processing contracts; and

  .   The resulting volumes of NGLs available for DMS' fee-driven downstream
      business.

Sensitivity to commodity prices varies at any point in time based on the
relative combination of the above factors. DMS intends to manage its commodity
price exposure by hedging its natural gas and NGL production within the limits
of market liquidity and credit availability. Typically, this hedging strategy
primarily focuses on the forward twelve months.

   In addition, DMS' business is dependent on producer drilling activity in the
producing regions that its gathering systems serve. At current natural gas
price levels, producers are actively drilling new wells and DMS' new connect
gas volumes for processing are currently growing enough to offset the natural
decline in production. The producers supplying DMS' facilities are primarily
independent producers who, as a group, react quickly to changes in gas prices.
As natural gas prices decline significantly from current levels, these
producers have historically reduced their drilling investment. If this occurs
going forward, DMS could experience difficulty in acquiring enough volumes to
offset natural declines. Conversely, as gas prices strengthen from current
levels, producers have historically invested more heavily in drilling and
development.

</TABLE>

   Operating Cash Flow.  Cash flow from operating activities totaled $149
million for the nine-month period ended September 30, 2002 compared to $457
million reported in the same 2001 period. Non-cash add-backs were greater in
the 2002 period, primarily due to the following charges, which are further
described in Notes 4 and 5 to the accompanying financial statements:

  .   The $737 million goodwill impairment associated with the WEN segment;

  .   The $62 million loss on the sale of Northern Natural;

  .   Write-offs within Earnings (Losses) from Unconsolidated Investments in
      the first three quarters of 2002 of $34 million representing technology
      investment impairments based on the Company's change in business strategy
      and continued downturn in the technology sector. Of the total write-offs,
      $32 million related to WEN, with the remaining amounts allocated to DMS
      and T&D. Additionally, the Company wrote off $62 million of generation
      investments in the third quarter 2002, all of which was associated with
      the WEN segment.

   Other changes in non-cash items include the following:

  .   Depreciation and amortization expense increased by $89 million primarily
      due to the inclusion of Northern Natural from February through July 2002
      and the United Kingdom natural gas storage facilities beginning in
      November 2001 offset by the discontinued amortization of goodwill in 2002;

                           AND RESULTS OF OPERATIONS
           For the Interim Periods Ended September 30, 2002 and 2001


  .   A reduction in Earnings (Losses) from Unconsolidated Investments of
      approximately $108 million related to West Coast Power;

  .   Deferred income taxes are a $97 million benefit position for the nine
      months ended September 30, 2002, compared to an expense of $137 million
      in the same 2001 period, producing a $234 million decreased add-back; and

  .   Risk Management activity produced a $444 million add-back, compared to a
      deduction of $76 million in the 2001 period. The add-backs represent cash
      realized for settled contracts in excess of gains recognized combined
      with non-cash losses realized in the period in excess of cash
      settlements, including the $223 million liquidity reserve recorded in the
      third quarter 2002.

   Changes in working capital had a negative impact on cash flow from
operations for the nine-month period ended September 30, 2002 primarily due to
the following:

  .   Increased cash collateral requirements resulting from the Company's below
      investment grade credit rating;

  .   Settlement of foreign exchange swaps; and

  .   Amortization of liabilities associated with previous acquisitions.

   Capital Expenditures and Investing Activities.  Cash provided by investing
activities during the nine-month period ended September 30, 2002 totaled $646
million. Capital spending and investments in unconsolidated investments totaled
$551 million and relate primarily to generation asset additions and
improvements, environmental compliance and first quarter investments in
technology infrastructure. Cash spent for the acquisition of Northern Natural
totaled $20 million, net of cash acquired. These cash outflows were offset by
$270 million in proceeds primarily from the sales of Northern Natural and the
Hornsea UK storage facility. Affiliate transactions totaled $862 million and
consisted primarily of cash received by the Company for Dynegy Inc.'s sale of
its preferred stock in Northern Natural. Other Investing activities include
proceeds from the sale of the Northern Natural bonds.

   Financing Activities.  Cash used in financing activities during the
nine-month period ended September 30, 2002 totaled $144 million.

   Long-term debt proceeds, net of issuance costs, for the nine-months ended
September 30, 2002 consisted of $496 million from the issuance of 8.75 percent
senior notes due February 2012 and $36 million from ABG. Repayments of
long-term debt totaled $409 million for the nine-months ended September 30,
2002 and consisted of the following:

  .   $90 million relating to the April 2002 purchase of Northern Natural's
      senior unsecured notes due 2005;

  .   $73 million in principle payments related to the Black Thunder financing;
      and

  .   $200 million relating to the July 2002 6.785% senior note repayment;

  .   $46 million relating to ABG.

   Net proceeds from short-term financing consisted of a $245 million net cash
advance for the anticipated sale of certain United Kingdom gas storage assets
as well as $192 million in financings secured by interests in two of the
Company's generating facilities. Additionally, during the nine months ended
September 30, 2002, Dynegy repaid $455 million in commercial paper and
borrowings under revolving credit lines and drew upon $53    million under the
Company's revolvers. Also, as more fully described in Note 1 in the
accompanying financial statements, the consolidation of ABG Gas Supply
increased cash flows from financing activities in 2001 by approximately $282
million.

   Finally, other financing cash payments totaled $14 million for the
nine-months ended September 30, 2002. These payments primarily consisted of $13
million in minority interest associated with Black Thunder prior to the
September 2002 restructuring (see Note 8 to the accompanying financial
statements for more information).

      capital in amounts or on terms that are considered favorable;

  .   Cost and other effects of legal and administrative proceedings,
      settlements, investigations and claims, including legal proceedings
      related to the terminated merger with Enron, the California power market

      insurance, as well as the SEC, FERC, CFTC and other similar
      investigations primarily surrounding Project Alpha and the Company's
      trading practices;

  .   Other North American regulatory or legislative developments that affect
      the regulation of the electric utility industry, the demand for energy
      generally, increase the environmental compliance cost for Dynegy's power

      owners of such facilities; and

  .   General political conditions and developments in the United States and in
      foreign countries whose affairs affect Dynegy's lines of business,
      including any extended period of war or conflict.

   Many of these factors will be important in determining Dynegy's actual
future results. Consequently, no forward-looking statement can be guaranteed.
Dynegy's actual future results may vary materially from those expressed or

ITEM 3--QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

   The Quantitative and Qualitative Disclosures About Market Risk are set forth
in "Item 2. Management's Discussion and Analysis of Financial Condition and
Results of Operations" herein.

ITEM 4--CONTROLS AND PROCEDURES

   Within the 90-day period immediately preceding the filing of this report, an
evaluation was carried out under the supervision and with the participation of

Accounting Officer (as Dynegy's responsible financial officer), of the
effectiveness of the design and operation of its disclosure controls and
