PEGASUS BLUE STAR FUND COMPLETES INVESTMENT IN CANCER TREATMENT SERVICES INTERNATIONAL

Apr 4, 2008

PITTSBURGH, Pennsylvania (April 4, 2008) – Pegasus Blue Star Fund announced today that it
has completed its investment in Cancer Treatment Services International, L.P. (“CTSI”), which
is developing an international network of integrated cancer treatment facilities. CTSI is
headquartered in Pittsburgh, Pennsylvania.

In order to improve access to advanced treatment modalities in regions of the world where
cancer treatment options are currently inadequate or nonexistent, CTSI is building an
international network of integrated cancer treatment facilities. “The investment by Pegasus Blue
Star Fund will enable CTSI to expand its operations in the U.S. and India, as well as penetrate
emerging markets such as China, Malaysia and Eastern Europe” says Chairman of the Board Dr.
Jeffery E. Shogan, M.D.

The investment in CTSI extends Pegasus Blue Star Fund’s holding in the healthcare space. Paul
Parmar, Chairman of Pegasus Blue Star Fund said, “We see CTSI’s service offerings as an
emerging trend in cancer treatment. The rapid advancement of medicine makes it harder and
harder for independent physicians to deliver comprehensive cancer treatment without the
centralized clinical and administrative support that comes with a true state-of-the-art network.”
CTSI’s business model focuses on a hub-and-spoke network model that is designed to focus on
1) patient care through the delivery of state-of-the-art, comprehensive outpatient service
offerings and 2) centralization and standardization of key processes and procedures. CTSI
currently operates a treatment center in Casa Grande, Arizona, and is developing treatment
centers in Hyderabad, India and Boca Raton, Florida. Additionally, CTSI has an extensive
development pipeline of projects it plans to begin during 2008, including facilities in China and
the U.S.

“We are excited to have partnered with Dr. Jeffery Shogan and Dr. Stanley Marks to support
their lifelong pursuit to improve cancer treatment. Their medical and business experience will
enable CTSI to become a worldwide leader in delivering cancer treatment abroad and here in the
U.S.” noted Darren Chaffee, Vice President at Pegasus Blue Star Fund, who led the deal on
behalf of Pegasus Blue Star Fund.
