* This representation is qualified by the fact that, as described in Item 4
of the Schedule 13D, UtiliCorp has the ability to vote or direct the vote
of the shares subject to the Stockholder's Voting Agreements only in two
limited, tax-related circumstances. UtiliCorp expressly disclaims
beneficial ownership to any shares of Common Stock that are subject to the
Stockholder's Voting Agreements.

** The percentage reflected in row 13 above is obtained by using 76,829,934
shares as the denominator (in accordance with Rule 13d-3(d)(1)(i)(B)). This
denominator includes: (a) 59,605,129 shares of Issuer's issued and
outstanding Common Stock (as indicated in Issuer's Form 10-Q filed on
November 14, 2001), and (b) 17,224,805 shares of Common Stock into which
Issuer's Convertible Preferred Stock held by UtiliCorp is convertible.

Also note that the percentage of Common Stock owned by UtiliCorp on a
partially diluted basis is approximately 36.04%. This percentage is
obtained by using 81,145,385 shares as the denominator, which includes (a)
the 76,829,934 shares discussed in the previous paragraph, (b) 1,152,055
shares of Limited Vote Common Stock (as indicated in Issuer's Form 10-Q
filed on November 14, 2001), and (c) 3,163,396 shares of Common Stock into
which the Issuer's Convertible Subordinated Notes can be converted.
UtiliCorp's ownership can be further diluted by (x) other classes of
Issuer's securities that can be converted into Common Stock and (y) shares
of Common Stock issuable under Issuer's Stock Option Plan.
