Your vote is important regardless of the number of TransGlobe Shares you own. It is very important that you carefully read the proxy related materials prepared for the meeting (the "Meeting Materials") and vote your TransGlobe Shares. You will be eligible to vote if you are a TransGlobe Shareholder of record at the close of business on August 24, 2022. To ensure that your TransGlobe Shares will be represented and voted at the Meeting, you should carefully follow the instructions provided in the Meeting Materials. All TransGlobe Shareholders are encouraged to vote by proxy or in person (virtually) at the Meeting. The deadline for the receipt of proxies is 9:00 a.m. MT on October 5, 2022. However, TransGlobe Shareholders are encouraged to vote their TransGlobe Shares as soon as possible in advance of the Meeting. Detailed instructions on how to vote and how to participate in the Meeting are contained in the Meeting Materials.
