Xsilva Unveils LightSpeed 2.5 Point of Sale for Mac

Next-generation retail solution leverages iPhone and Leopard

MONTREAL, QUEBEC, CANADA -- November 28, 2007 - Xsilva Systems, Inc. has
released LightSpeed 2.5, a new version of the popular, easy-to- use Point
of Sale (POS) solution on Mac OS X--with more reasons than ever for
retailers and small businesses to choose Macintosh as their POS platform.

"With LightSpeed 2.5, Point of Sale on Mac gets even better," said Xsilva
CEO, Dax Dasilva. "Now retailers can view LightSpeed Stats on their iPhone
to get the latest details on sales anywhere, anytime--and use Cover Flow in
both the LightSpeed browser and POS screen to quickly and effortlessly find
the product or customer information they need."

LightSpeed 2.5 also debuts two highly requested features: Multi-Store
Transfers for moving stock between store locations; and a Label Designer
for custom product label templates.

LightSpeed 2.5 highlights:

- iPhone Stats

Now retailers can track sales, payments, returns, and invoice count for the
day, the week, the month or even the year-- with LightSpeed Stats on their
iPhone. They can also see which employees are clocked in at the store, when
they started, and how much time they've spent on Jobs and Tasks. And
contacting an employee directly is as easy as tapping their phone number or
email address.

- Cover Flow Interface

The same Cover Flow interface that makes finding information on iTunes and
the iPhone fast and fun makes it easy to zero in on information in the
LightSpeed Browser and on the LightSpeed POS screen.

- Multi-Store Transfers

LightSpeed 2.5 makes it easy to transfer stock from one store's database to
another and receive stock with ease. Browsing and management tools make it
easy to review 'transfer in' and 'transfer out' documents, run reports on
inventory 'in transit' and export information to accounting software such
as QuickBooks.

- Label Designer

Now it's easy to go beyond pre-made product label layouts and design your
own custom labels. Want a use a different label size? Want to import a
boutique logo? The new Label Designer provides easy-to-use graphical layout
tools to create all types of product labels.
