License agreement with TomoTherapy terminated

In 2007, RaySearch Laboratories AB and TomoTherapy Incorporated (now Accuray)
entered into a software licensing and development agreement. Under the
agreement, RaySearch developed a product named SharePlan, which was launched by
TomoTherapy in 2009.

SharePlan is an advanced treatment planning solution that enables transfer of
treatment plans between TomoTherapy systems and conventional linear
accelerators. The product uses highly sophisticated algorithms to automatically
generate a selection of deliverable high-quality IMRT plans based on an existing
TomoTherapy treatment plan. This time-saving concept is an important tool for
optimizing patient benefit and throughput at clinics that have a mixed
environment with both TomoTherapy systems and conventional linear accelerators.

Now RaySearch and Accuray have agreed to cancel the agreement and end the
partnership. Although the partnership will be ending, Accuray and RaySearch are
committed to ensuring that customer needs are supported and maintained. As a
result, SharePlan functionality will continue to be available for new and
existing customers as an integrated module in RaySearch’s RayStation® treatment
planning system that is sold and marketed by RaySearch. Existing SharePlan
customers will be offered a free upgrade to RayStation®.

“Since the original agreement was signed, a lot has changed for both companies
so this solution makes good sense for both parties. RayStation® was not
available four years ago so back then a stand-alone application was the best
solution. Now however, we can offer the same functionality in RayStation® which
is evolving very rapidly and also gives the TomoTherapy System users the option
to select other features and advanced treatment planning tools. This is
attractive for the customers and Accuray alike as it expands the product
offering for these customers”, says Johan Löf, CEO of RaySearch.
