On February 16, 2024, at a Special Meeting (the “Special Meeting”) of the stockholders of 180 Life Sciences Corp. (the “Company,” “we,” “our,” or “us”), the stockholders of the Company approved the Second Amendment (“Second Amendment”) to the First Amended and Restated 180 Life Sciences Corp. 2022 Omnibus Incentive Plan (the First Amended and Restated 2022 Omnibus Incentive Plan, as amended by the Second Amendment, the “OIP”) in accordance with the voting results set forth below under Item 5.07. The Second Amendment was originally approved by the Board of Directors of the Company on December 13, 2023, subject to stockholder approval and the Second Amendment became effective at the time of stockholder approval.

The material terms of the OIP, as amended by the Second Amendment, were described in the Company’s Definitive Proxy Statement on Schedule 14A (the “Proxy Statement”) under the caption “Proposal 2 – Adoption of the Second Amendment to the 180 Life Sciences Corp. 2022 Omnibus Incentive Plan” filed with the Securities and Exchange Commission (SEC) on December 26, 2023. Awards under the OIP may be made in the form of performance awards, restricted stock, restricted stock units, stock options, which may be either incentive stock options or non-qualified stock options, stock appreciation rights, other stock-based awards and dividend equivalents. Awards are generally non-transferable. Subject to adjustment in connection with the payment of a stock dividend, a stock split or subdivision or combination of the shares of common stock, or a reorganization or reclassification of the Company’s common stock, the aggregate number of shares of common stock which may be issued pursuant to awards under the OIP is 4,249,933. The 4,249,933 share limit also applies to the total number of incentive stock options which may be awarded pursuant to the terms of the OIP. The Second Amendment increased the maximum number of shares available to be issued under the OIP from 470,000 shares to 4,249,933 shares.

Employees, non-employee directors, and consultants of the Company and its subsidiaries are eligible to participate in the OIP. Incentive stock options may be granted under the OIP only to employees of our company and its subsidiaries. Employees, directors and consultants of our company and its affiliates are eligible to receive all other types of awards under the OIP.

The above description of the Second Amendment and the OIP does not purport to be complete, and is qualified in its entirety by reference to the full text of the Second Amendment and the OIP as amended by the Second Amendment, which are attached hereto as Exhibits 10.1 and 10.2, and are incorporated by reference into this Item 5.02.
