Madison, WI – February 24, 2004 – TomoTherapy Incorporated announced today that the company has successfully completed a $7.0 million round of equity financing that included participation by Ascension Health Ventures, LLC (AHV) of St. Louis and the company’s current investors. TomoTherapy is a Wisconsin-based company that has developed a revolutionary new medical system to deliver conformal radiation therapy to cancer patients. AHV is the strategic venture investing subsidiary of Ascension Health, the largest nonprofit health system in the U.S.

The TomoTherapy Hi·Art System® is designed to target radiation treatment to the patient’s tumor while helping to limit damage to the surrounding tissues. Using a ring design, the Hi-Art System delivers a sophisticated form of image-guided IMRT, or intensity modulated radiotherapy, and integrates treatment planning, patient positioning and treatment delivery in one system. The company received FDA clearance for the device in 2002.

“Improving cancer care in our System is a priority among our leaders and clinicians,” said John Doyle, president of Ascension Health Ventures. “To participate with the TomoTherapy team in the future development of this technology is exciting for Ascension Health.”

“Our decision to purchase the TomoTherapy Hi·Art System was based on a careful evaluation of competing technologies offered by several radiotherapy vendors,” said Timothy Holmes, PhD, director of medical physics at St. Agnes Hospital in Baltimore, an Ascension Health facility. “It became obvious that the Hi·Art System is the next generation of external beam radiation treatment delivery. I am truly impressed with the design of the Hi·Art System and very grateful to be a part of the acquisition and implementation of helical tomotherapy at St. Agnes Cancer Center.”
“We are pleased to have Ascension Health and their clinical teams involved in the implementation of the TomoTherapy technology across the country,” said John Barni, CEO of TomoTherapy. “The input of the Ascension Health clinicians will be very valuable as we continue to develop and improve this new, image-guided cancer

treatment system. We intend to use this funding to accelerate such future growth opportunities.”
In addition to the $3.0 million raised from AHV, several existing investors also participated in this round, including The Endeavors Group LLC, Avalon Technology LLC, Venture Investors, Open Prairie Ventures, and the State of Wisconsin Investment Board.
