securities laws of any other jurisdiction. The Notes will not be qualified by a prospectus in Canada. Unless they

are registered or qualified by a prospectus, the Notes may be offered and sold, only in transactions that are exempt

from registration requirements and from prospectus qualification under Canadian securities laws. In the United

States, the Notes will be offered and sold, only to “qualified institutional buyers” (as defined in Rule 144A under

the Securities Act) and outside the United States, to non-U.S. persons in compliance with Regulation S under the

Securities Act.

This press release is neither an offer to sell nor the solicitation of an offer to buy the Notes, the Existing Notes or

any other securities and shall not constitute an offer to sell or solicitation of an offer to buy, or a sale of, the Notes,

the Existing Notes or any other securities in any jurisdiction in which such offer, solicitation or sale is unlawful.

This press release does not constitute a notice of redemption with respect to the Existing Notes.
