These securities may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective. The registration statement, any amendment or supplement to the registration statement and the documents incorporated by reference therein (including the Kenon lockup agreement) are available at the SEC's website at www.sec.gov. A written prospectus for the offering meeting the requirements of Section 10 of the Securities Act of 1933 (other than a free writing prospectus as defined in Rule 405) including as to the identified paragraphs above a price range where required by rule, may be obtained from the underwriters in ZIM's offering.
