Cascal N.V.'s Board Rejects Inadequate and Coercive Sembcorp Offer; Advises Shareholders To Take No Action

LONDON, April 26, 2010 - Cascal N.V. (NYSE: HOO) — The Board of Directors of Cascal today
rejected as inadequate and coercive a proposed acquisition of Cascal by
Sembcorp Industries Ltd. through its wholly owned subsidiary, Sembcorp
Utilities Pte Ltd ("Sembcorp"). Sembcorp today announced that it intended to
make an offer to acquire Cascal's outstanding common shares for US$6.75 per
share in cash, which consideration would be reduced to US$6.40 per share in
the event that Sembcorp is not able to acquire at least 80% or more of
Cascal's outstanding shares.

Cascal, through an independent committee of directors, recently rejected
a similar offer by Sembcorp.

"Cascal is not seeking to sell itself at this time. Sembcorp's announced
two-tiered and below market offer appears to be intended to force
shareholders to sell their securities at an inadequate price or risk both a
reduction in the consideration offered to them and a loss of access to a
liquid market for their securities," said Michael Wager, Chairman of the
Special Committee of the Board of Directors of Cascal. "Cascal intends to do
all things necessary to protect its shareholders from Sembcorp's inadequate
and unsolicited offer."

The proposed offer was made in connection with a privately-negotiated
transaction between the Sembcorp and Biwater Investments Limited ("Biwater").
Cascal understands that Sembcorp has entered into an agreement with Biwater
to acquire Biwater's 17,868,543 shares in Cascal.

The offer was not solicited by Cascal. Cascal's common shares closed at
US$7.61 per share on Friday, April 23, 2010.
