ITEM 5. OTHER EVENTS.

     On July 15, 2002, Dynegy Inc. ("Dynegy") issued a press release announcing
that it will adjust its previously disclosed estimated second quarter pre-tax
charge from $450 to $500 million. The adjustment is the result of an increase in
an expected non-cash charge in the company's natural gas marketing business. A
portion of the expected natural gas marketing charge was included in Dynegy's
June 24, 2002 estimate for the second quarter charge. Dynegy has since
determined, through a balance sheet review and reconciliation process started
early in 2002, that the natural gas marketing charge will be approximately $125
million. Management believes the charge is largely associated with the process
of reconciling accrued to actual results in its natural gas marketing business
and that it accumulated over a number of years.

     Dynegy will record the natural gas marketing charge at the end of the
second quarter and, if necessary, correct prior period financial statements
based on its continuing review process to determine the periods affected. Dynegy
has requested that its independent auditor, PricewaterhouseCoopers, re-audit its
financial statements for 1999 and 2000. PricewaterhouseCoopers is already
conducting a re-audit of Dynegy's 2001 financial statements. Dynegy estimates
that it will take the remainder of the year to complete the three-year re-audit.
PricewaterhouseCoopers will conduct an interim review of Dynegy's quarterly
financial statements for 2002 once the re-audit has been completed.

     Dynegy also announced that it expects the criteria for and interpretation
of hedge accounting under the Statement of Financial Accounting Standards No.
133 ("FAS 133") to be one of the issues addressed in the re-audits. FAS 133
governs whether derivative transactions should be accounted for on the basis of
accrual or mark-to-market accounting. During the five-quarter period ended March
31, 2002, Dynegy accounted for certain derivative transactions as hedges of its
generation facilities. Dynegy received in cash and recognized operating margin
of approximately $80 million in such hedge transactions on an accrual basis over
the five quarters. If Dynegy's accounting treatment relating to FAS 133 were to
change as a result of the re-audit, the income recognized over the five quarters
may be re-allocated within the period. Cash flow for the five-quarter period
would remain unaffected by a change in the timing of income statement
recognition, if any.

     Dynegy also provided an update on its liquidity and financial position,
stating that it has maintained adequate liquidity to meet its current
obligations and commitments. Dynegy further announced that it completed a $200
million interim financing which matures in six months and is secured by
interests in the Renaissance and Rolling Hills merchant power generation
facilities. After taking into account the $200 million financing and July 15
maturities of $200 million at Dynegy Holdings Inc. and $96 million at Illinois
Power Company, Dynegy stated that its liquidity remains above $900 million.

exhibit 99.1 and is incorporated herein by this reference.
