United BioSource Corporation Receives $125 Million Growth Equity Investment

BETHESDA, Md.--(Business Wire)--
United BioSource Corporationtoday announced that Berkshire Partners LLC, a
Boston-based private equity firm, has made a $125 million growth equity
investment to support the Company`s evidence-based acquisition and service
offering expansion strategy.

Formed in 2003 by Ethan D. Leder and Mark P. Clein, the rapidly growing
Bethesda, Maryland based United BioSource Corporation(UBC) partners with life
sciences companies to develop and commercialize medical products globally by
providing authoritative, impartial and timely real-world evidence that
demonstrates safety, efficacy and value. UBC now has offices in more than 20
countries across the globe with over 1,300 employees.

"With this additional capital investment, we are well positioned to continue our
targeted growth strategy recognizing that over the last six years, a steady and
accelerating momentum has been building among regulators, payors, physicians and
patients for new requirements and standards that go beyond FDA approval and the
traditional drug development process. These demands relate to the provision of a
continuous stream of evidence of product safety, economic value and medical
effectiveness in the peri- and post-approval environment. UBC was created to
address these challenges and the demands of the healthcare marketplace have only
intensified in recent years in this respect. In Berkshire, we found an
additional partner who shares our vision and excitement for our future," said
Ethan Leder, CEO of United BioSource.

"UBC`s management team has an impressive record of successfully integrating
acquisitions, creating value across business lines and servicing the world`s
most progressive life sciences companies. We are excited to have a chance to
partner with a clear leader and innovator in this space," said Randy Peeler,
Managing Director of Berkshire Partners. "We look forward to working together
with UBC`s management and founding investors to help UBC capitalize on the many
growth opportunities we have identified in this dynamic and demanding
marketplace."
