YOUR VOTE IS IMPORTANT

In order to ensure your representation at the General Meeting, whether or not you plan to attend the meeting, please vote your shares as promptly as possible over the internet by following the instructions on your proxy card. Your participation will help to ensure the presence of a quorum at the General Meeting and save the Company the extra expense associated with additional solicitation. If you hold your shares through a broker, bank or other nominee, your broker, bank or other nominee is not permitted to vote on your behalf in the approval of change of the name of the Company from “JAB Acquisition Corp I” to “Atlantic Acquisition Corp I” (Proposal 1), an amendment to the Company’s current memorandum and articles of association (Proposal 2) and the adjournment of the General Meeting to a later date or dates, or indefinitely (Proposal 3) unless you provide specific instructions to your broker, bank or other nominee by completing and returning any voting instruction form that your broker, bank or other nominee provides or following instructions that allow you to vote your broker-held shares via the internet. Voting your shares in advance will not prevent you from attending the General Meeting, revoking your earlier submitted proxy or voting your shares during the General Meeting.
