Q: Will my shares be voted if I do not sign and return my proxy card?
A: They could be, but not for the approval of the adoption of Southern Unions Third Amended and Restated 2003 Stock and Incentive Plan. If your shares are held in street name and you do not instruct your broker, bank or other nominee how to vote your shares, pursuant to NYSE rules, your broker, bank or nominee may either use its discretion to vote your shares on routine matters or leave your shares unvoted. For any non-routine matters being considered at the meeting (such as the adoption of Southern Unions Third Amended and Restated 2003 Stock and Incentive Plan), your broker or other nominee would not be able to vote on such matters. If your shares are held in street name, your broker, bank or nominee will include a voting instruction card with this Proxy Statement. We strongly encourage you to vote your shares by following the instructions provided on the voting instruction card. Please return your proxy card to your broker, bank or other nominee and contact the person responsible for your account to ensure that a proxy card is voted on your behalf.
