## ARTICLE I.

#### PURPOSE, SCOPE AND COMPONENTS OF THE PLAN
1.1. Purpose and Scope . The purpose of the Calix, Inc.

In the event the Company’s stockholders fail to approve the Matching Component of the Plan as set forth herein at the annual meeting of the Company’s stockholders in 2025, then this Plan shall be deemed void ab initio and the Prior Plan shall continue in effect in accordance with its terms.
