<p><font face="Arial" size="2">During the
course of October 24 through October 25, 2005, Mentor Corporation (&quot;the
Company&quot;) mistakenly sent a fax message with an attached letter, which was in
draft form, to a portion of the investigators participating in the Company's
adjunct study for its silicone gel-filled breast implants.&nbsp; The draft letter
attachment was intended to be sent only in the potential event of a
notification from the Food and Drug Administration (&quot;FDA&quot;) of an approval of
the Company's pre-market approval (&quot;PMA&quot;) application for its silicone
gel-filled breast implants, and was clearly marked &quot;<i>[SAMPLE LETTER -
Contingent on Final FDA Approval of Devices]</i>&quot;.&nbsp; The fax message was
prepared to inform adjunct study investigators of their subsequent obligations,
and to address appropriate actions that would be required, in the event FDA approved
the PMA application.&nbsp; Upon learning that the fax message with attachment was
being sent in error, the Company immediately ceased sending it to the remaining
study investigators.&nbsp; Subsequently, following discussions with the FDA, the
Company took immediate steps to correct the error and sent follow-up
correspondence to those study investigators on October 27, 2005.&nbsp; The Company
understands that this issue was resolved to FDA's satisfaction.</font></p>



<p><font face="Arial" size="2">The PMA for
the Company's silicone gel-filled breast implants continues to be under review
