Update on the collaboration between RaySearch and Varian

Varian Medical Systems and RaySearch Laboratories are engaged in a long-term
strategic collaboration agreement in which RaySearch will develop advanced
software for integration into Varian's Eclipse™ treatment planning system.

The collaboration involves a number of components aimed at improving radiation
treatments, such as products for radiobiological optimization and optimization
of conventional 3D-CRT treatments. The first product from the collaboration was
previously expected to be released during 2008. This has been postponed and now
the three products for radiobiological evaluation, radiobiological optimization
and optimization of conventional 3D-CRT plans are all expected to be available
to clinicians during the first half of 2009.

“Varian is a very important partner to us and we are dedicating substantial
resources to our joint development project,” says Johan Löf, President and Chief
Executive Officer of RaySearch. “The product development is progressing well and
the first three products are all planned to be demonstrated at the upcoming
trade shows and released during the first half of next year,” concludes Johan
Löf.
