TomoTherapy Completes Acquisition of Linear Accelerator Manufacturer in China

MADISON, Wis. - Nov. 4, 2008 - TomoTherapy Incorporated (NASDAQ: TOMO), maker of the Hi·Art® treatment system for advanced radiation therapy, announced today that it has finalized the agreement to acquire privately held linear accelerator manufacturer Chengdu Twin Peak Accelerator Technology Inc., based in Chengdu, China.

A linear accelerator (linac) is a key component in radiation therapy systems used to create high-energy x-rays for cancer treatments. The linear accelerators designed, developed and manufactured by Twin Peak will be used to supplement TomoTherapy's existing supply source.

According to Steve Books, chief operating officer of TomoTherapy, 'With the acquisition of Twin Peak, we are reducing our sole supplier risk associated with our linac supply, a critical component to the Hi·Art treatment system. This acquisition will also expand TomoTherapy's competency in design and manufacturing of linear accelerators which is expected to improve Hi·Art system reliability and positively impact margins.'

Chengdu Twin Peak Accelerator Technology Inc. designs and manufactures linear accelerators for medical equipment. It is located in the provincial capital of Sichuan, China.
