STOCK PLUS INVESTMENT PLAN: In April 2000, Wisconsin Energy discovered that, due
to an administrative error, sales of Wisconsin Energy common stock under
Wisconsin Energy's dividend reinvestment and stock purchase plan, the Stock Plus
Investment Plan, exceeded the amount of shares registered for the Plan under the
Securities Act of 1933 beginning in December 1999. Upon discovery of the error,
Wisconsin Energy promptly took steps to register additional shares for the Plan.
The oversales amounted to 124,622 shares in December 1999 for an aggregate of
$2,451,702; a total of 615,754 shares in the first quarter of 2000 for an
aggregate of $11,242,716; and 78,963 shares through April 3, 2000 for an
aggregate of $1,576,794. (Added by Wisconsin Energy's amendment No. 1 on Form
