The following information shall not be deemed "filed" for purposes of Section 18
of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or
incorporated by reference in any filing under the Securities Act of 1933, as
amended, or the Exchange Act, except as shall be expressly set forth by specific
reference in such a filing.
On October 28, 2004, Charles River Laboratories International, Inc. issued a

of 1995, as amended, indicating that certain statements about Charles River's
business contained in the press release are "forward-looking" rather than
historic. The press release also states that these and other risks relating to
Charles River are set forth in the documents filed by Charles River with the
Securities and Exchange Commission.
