 Following the ESPP’s effectiveness, offering periods will not commence under the ESPP until determined by the administrator of the ESPP.

Both the CCIX Board and PlusAI Board believe that an employee stock purchase plan will be an important factor in attracting, motivating, and retaining qualified personnel who are essential to our success. The ESPP provides a significant incentive by allowing employees to purchase shares of Post-Closing Company Class A common stock at a discount. The CCIX Board will approve the ESPP, subject to the approval of CCIX shareholders. If CCIX shareholders do not approve the ESPP, the ESPP will not become effective.
