Events</b></font></p>

<p style='text-indent:.5in'><font face="Times New Roman" size="2">On September 5, 2007, Mentor
Corporation (&quot;Mentor&quot; or &quot;the Company&quot;) announced that, after consulting with
Institutional Shareholder Services and certain of its shareholders, its board
of directors has adopted a policy regarding designation of preferred stock.&nbsp; At
the upcoming annual meeting of Mentor's shareholders to be held on September
17, 2007, shareholders are being asked to approve an amendment to Mentor's
Restated Articles of Incorporation to increase the total number of shares of
authorized capital stock and to provide for the issuance of preferred stock in
one or more series, with rights, preferences, privileges and restrictions to be
determined by the board of directors in its discretion.&nbsp; In order to address
concerns regarding the use of the preferred stock, the Mentor board has adopted
a policy requiring that, unless approved by the vote of the shareholders, any
designation of preferred stock in connection with the adoption of a shareholder
rights plan include provisions effecting the termination of that plan within
one year.&nbsp; The policy also requires that other uses of preferred stock be
limited to bona fide capital raising or business acquisition transactions.</font></p>



<p style='text-indent:.5in'><font face="Times New Roman" size="2">As disclosed in the proxy statement
distributed in connection with the upcoming annual meeting of shareholders, Mentor has no current plans to issue preferred stock, nor is Mentor aware of any proposed
takeover or other transaction that could propel it to consider such issuance.
Rather, this proposal to approve the creation of preferred stock is designed to
provide Mentor's board of directors with the flexibility to issue such
preferred stock, should they, at some time in the future, determine that such
measures are necessary or desirable.&nbsp; Shareholders and other investors are
urged to read the proxy statement, which contains important information that
should be read carefully before any decision is made with respect to all
proposals, including the proposal to approve the creation of the preferred
stock.</font></p>

Events
On September 5, 2007, Mentor
Corporation ("Mentor" or "the Company") announced that, after consulting with
Institutional Shareholder Services and certain of its shareholders, its board
of directors has adopted a policy regarding designation of preferred stock.  At
the upcoming annual meeting of Mentor's shareholders to be held on September
17, 2007, shareholders are being asked to approve an amendment to Mentor's
Restated Articles of Incorporation to increase the total number of shares of
authorized capital stock and to provide for the issuance of preferred stock in
one or more series, with rights, preferences, privileges and restrictions to be
determined by the board of directors in its discretion.  In order to address
concerns regarding the use of the preferred stock, the Mentor board has adopted
a policy requiring that, unless approved by the vote of the shareholders, any
designation of preferred stock in connection with the adoption of a shareholder
rights plan include provisions effecting the termination of that plan within
one year.  The policy also requires that other uses of preferred stock be
limited to bona fide capital raising or business acquisition transactions.
As disclosed in the proxy statement
distributed in connection with the upcoming annual meeting of shareholders, Mentor has no current plans to issue preferred stock, nor is Mentor aware of any proposed
takeover or other transaction that could propel it to consider such issuance.
Rather, this proposal to approve the creation of preferred stock is designed to
provide Mentor's board of directors with the flexibility to issue such
preferred stock, should they, at some time in the future, determine that such
measures are necessary or desirable.  Shareholders and other investors are
urged to read the proxy statement, which contains important information that
should be read carefully before any decision is made with respect to all
proposals, including the proposal to approve the creation of the preferred
stock.

of preferred stock.  These forward-looking statements are based on the
Company's current expectations, management's beliefs and certain assumptions
