OAKDALE, Minnesota and BOULDER, Colorado, March 10, 2010 - Imation Corp. (NYSE: IMN), a global leader in removable data storage and
a founding member of the RDX Storage Alliance, together with ProStor Systems,
the leader in enterprise-class removable disk storage systems for business
backup, archiving, and long-term data retention and management, today
announced Imation has extended its RDX(R) license agreement with ProStor
Systems. Under the terms of the agreement, Imation will have a license to
manufacture, market and sell RDX removable hard disk systems through 2020.
Further underscoring the company's commitment, Imation also announced that it
has invested US$5 million to help advance ProStor's technology.

"Removable hard disk storage, which addresses the need for
cost-effective, scalable storage for small and medium businesses, is a
fast-growing and important segment of the data storage market. The RDX system
is clearly the industry standard for removable hard disk storage," said
Subodh Kulkarni, chief technology officer and senior vice president of the
global commercial business for Imation. "Through our extended licensing
agreement with ProStor Systems, we are demonstrating our commitment to the
RDX solution, and to our customers worldwide who want the combined benefits
of disk and tape that RDX offers. We are enthusiastic about ProStor Systems'
roadmap for RDX, and are investing in the technology to help drive the
development of new RDX offerings for our customers."

"RDX momentum continues to grow, and Imation's long-term investment in
this format is another significant milestone in the industry's adoption of
RDX," said Frank Harbist, president and chief executive officer, ProStor
Systems. "Leading OEMs like Dell, IBM, and HP have provided RDX-based
solutions to more than 200,000 customers worldwide and that number is
growing. A company like Imation, with deep technology strength based on more
than 50 years in the data storage industry and extensive global distribution
reach, is an excellent partner for both ProStor RDX and InfiniVault(R). We
look forward to continuing to work with Imation to deliver the next
generations of our RDX technology roadmap as well as other storage
solutions."
