sales agent or underwriter has authorized anyone to provide you with different information. If anyone provides you with different or inconsistent
information, you should not rely on it. We are not, and the Agents and any underwriters are not, making an offer to sell the securities

with the SEC before the date of this prospectus supplement, on the other hand, you should rely on the information in this prospectus supplement.
