FOR IMMEDIATE RELEASE

DayLite Version 1.7.4 & DayLite Mail Integration Module (DMI) 1.1 – Now on
Tiger!

TORONTO, CANADA — April 28, 2005 — Marketcircle Inc. today announced the
release of DayLite v1.7.4, a new version of its business relationship
manager. This update includes compatibility with Apple’s newest operating
system, Mac OS X v10.4 “Tiger”. DayLite v1.7.4 is a required update due to
the fact that DayLite v1.7.3 and lower will not run on Tiger.

Marketcircle Inc. today also announced the update release of DayLite Mail
Integration Module (DMI) v1.1, designed to tightly integrate DayLite with
Apple Mail. DMI v1.1 includes compatibility for Mac OS X Tiger Mail 2. This
update is required as DMI v1.0 is not compatible with Tiger Mail 2.

“A recent pre-release of Tiger unexpectedly broke DayLite v1.7.3. With
DayLite being crucial to the operation of many of our customers’
businesses, our engineers and the team at OpenBase pulled together to
deliver a solid Tiger compatible release,” says Alykhan Jetha (AJ),
President of Marketcircle Inc. “Tiger brings many new useful features to
the Mac and we didn’t want DayLite to hold our customers back from taking
advantage of them now!”

DayLite v1.7.4 and DMI v1.1 will run on both Mac OS X v10.3.5 – v10.3.9 and
v10.4. Both will be available in advance of the April 29th unveiling of Mac
OS X v10.4 “Tiger”.
