Mentor Enters into Definitive Acquisition Agreement with Shareholders of Perouse Plastie

Mentor Corporation (NYSE:MNT) announced today that it has entered
into a definitive agreement to acquire all of the outstanding shares
of Perouse Plastie SAS (Perouse), a medical device company based in
Bornel, France. The transaction is subject to customary closing
conditions and is expected to be completed in July.

Perouse is a rapidly growing manufacturer and distributor of
silicone gel breast implants for a number of established and emerging
international markets, and sells its products under the Perouse
Plastie Perthese(R) brand. Perouse's primary manufacturing facility is
located in France.

"This acquisition will increase our leadership in several
international markets and represents our commitment to expanding our
market presence in the surgical aesthetics field," said Joshua H.
Levine, President and Chief Executive Office of Mentor. "The Perouse
product offering is complementary with Mentor's aesthetic products and
the combination will allow us to better serve physicians and their
patients."

Under the terms of the agreement, Mentor will acquire all of the
shares of Perouse for a total enterprise value of 42 million Euros,
including the assumption of approximately 3 million Euros in net debt.
The purchase price is subject to customary post-closing adjustments
and indemnifications. Mentor will update its financial guidance for
fiscal year 2008 and provide an estimate of costs that may be excluded
from adjusted earnings per share at the time of Mentor's first quarter
2008 earnings release. At this time, Mentor does not believe that the
Perouse acquisition will have a materially accretive or dilutive
effect on adjusted earnings per share for fiscal year 2008.

"We are very pleased with this acquisition as Perouse has
manufacturing capabilities which will expand our capacity and ability
to meet growing customer demand for silicone gel breast implant
products worldwide," said Ed Northup, Vice President and Chief
Operating Officer of Mentor. "Perouse's focus on product quality and
customer service makes this a very complementary fit with our breast
implant business."
