Allogene Therapeutics, Inc., a Delaware corporation (the “Company”), filed its amended and restated certificate of incorporation on October 15, 2018 (the “Certificate of Incorporation”) with the Secretary of State of the State of Delaware. The Company also adopted amended and restated bylaws that became effective on October 15, 2018 (the “Bylaws”). Article VII of the Certificate of Incorporation and Article XV of the Bylaws each provides in part, that, unless the Company consents in writing to the selection of an alternative forum, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933 (such provision, a “Federal Forum Provision”).

On December 19, 2018, the Delaware Court of Chancery issued a decision in Matthew Sciabacucchi v. Matthew B. Salzberg et al., C.A. No. 2017-0931-JTL (Del. Ch.), finding that provisions such as the Federal Forum Provision are invalid under Delaware law. In light of this decision of the Delaware Court of Chancery, the Company does not intend to enforce the Federal Forum Provision in the Certification of Incorporation and in the Bylaws unless and until such time that the Court of Chancery, or the Delaware Supreme Court, determines that such a provision is valid under Delaware law. To the extent the Delaware Supreme Court makes a final determination that provisions such as the Federal Forum Provision are invalid as a matter of Delaware law, the Company’s Board of Directors intends to amend the Bylaws to remove the Federal Forum Provision in the Bylaws and anticipates seeking stockholder approval to amend the Certificate of Incorporation to remove the Federal Forum Provision in the Certification of Incorporation.
