Orion - Company Announcement

Orion clarifies information emanating from Capital Markets Day

ORION CORPORATION          STOCK EXCHANGE RELEASE        4 DECEMBER
2009 at 17.00 p.m.

Orion Corporation is clarifying information emanating from the
Capital Markets Day on 1 December 2009 concerning the number of
companies that have submitted Abbreviated New Drug Applications
("ANDAs") in the United States for generic versions of Orion's
entacapone products. As previously announced, companies of two Groups
have submitted ANDAs that challenge the US entacapone basic patent no
5,446,194, which expires on 19 October 2013. Lawsuits have been
initiated against these companies, one of which has been settled, as
announced by Orion on 29 April 2009. In addition, Orion is aware that
a third applicant has submitted an ANDA that challenges only a patent
that will expire after the expiry of the entacapone basic patent, and
this application has not given Orion cause to file a lawsuit or take
further action.

Orion is issuing this release because the number of companies that
have submitted ANDAs could have been misunderstood from the
discussions at the Capital Markets Day, and this misunderstanding has
appeared in some analysts' reports following the Capital Markets Day.

Orion stresses that it does not regard as material to the Company's
communication any application by an applicant for an ANDA to launch
its generic products in the markets only after the expiry of the
entacapone basic patent. More over, Orion does not regard information
about the number of companies that have submitted ANDAs as in itself
material to the Company. Orion will continue to announce in stock
exchange releases all ANDAs known to the Company for generic versions
of entacapone products submitted in the United States that it
considers might have a material effect on the Company's share value.
The Company does not generally publish information about other
applications.
