Aliso Viejo, CA - September 28 2005 - Allume Systems, Inc., a division of
Smith Micro Software Inc. (NASDAQ: SMSI), today released Aquazone Seven
Seas Deluxe, the latest catch in the AQUAZONE family and the first version
available for both Windows and Mac OS X operating systems. Seven Seas
Deluxe includes 40 different kinds of fish from goldfish, clown fish,
jellyfish, sea turtles, a giant sunfish, a shark and more! Already on of
the best selling interactive aquariums on the PC, Seven Seas Deluxe allows
Mac users to enjoy own their own virtual aquarium.

Aquazone was the first virtual aquarium to bring an interactive element to
user's computer. In addition to Aquazone's realistic fish, tanks, and
lighting effects, users can "feed" their virtual fish or "tap" on the tank
to see their fish react. Aquazone is also unique in its ability to display
virtually unlimited numbers of fish, even whole schools of some species.

"Aquazone is exciting because of the amazing realism," said David Polzine,
Product Manager at Allume Systems, Inc. "It is the only virtual aquarium
which allows interaction with your fish to "feed" them, "tap" on the tank
or even follow a favorite fish via a virtual 'fish cam' and now with Seven
Seas Deluxe users have the best selection of fish available. But the best
part of Aquazone is you get the pleasure of owning fish even a shark,
without having to clean-up after them"
