Medidata Solutions and ICON Reach Two-Year Partnership Milestone

Medidata Solutions, a global provider of electronic clinical data
capture (EDC), management and reporting solutions, and ICON, a global
provider of outsourced development services, today reached a two-year
milestone in their partnership.

Since February 2005, the companies have worked together to deliver
Medidata's Rave EDC platform to biopharmaceutical companies around the
globe and to date, ICON and Medidata have been awarded contracts from
19 companies for 37 clinical trials across Phases I-IV, in a range of
therapeutic areas.

ICON, an early adopter of EDC technology, was Medidata's first
ASPire to Win(TM) partner. This program, which is based on a
non-exclusive application service provider (ASP) partnership and
business model, has enabled ICON to meet sponsor demand for Medidata
Rave(R). ICON has been able to offer the platform in-house by building
and deploying studies with Rave certified resources, while the program
has also allowed Medidata to implement Rave with a range of sponsors
looking to streamline global clinical trials.

"ICON's proven ability to provide clinical research process and
data management expertise complements Medidata's industry-leading
technology and hosting services, offering sponsors a robust and
flexible Rave implementation model," said Tarek Sherif, CEO of
Medidata Solutions. "We value our partnership with ICON and anticipate
further success in 2007."

Tom O'Leary, Global Head of Data Management at ICON, added, "Our
partnership with Medidata has proven extremely beneficial in enabling
us to offer our growing customer base with a user-friendly, flexible
solution to help drive further adoption of EDC for clinical trials
worldwide. We look forward to building on the success of the past two
years as we continue to provide innovative solutions to clients
throughout 2007 and beyond."

Through this partnership, ICON and Medidata will continue to work
together on marketing initiatives that demonstrate how EDC technology
adoption can significantly enhance the clinical trials process.
