Our records indicate that you have not yet voted your units. YOUR BOARD OF SUPERVISORS HAS UNANIMOUSLY RECOMMENDED THAT YOU VOTE "FOR" ALL OF THE PROPOSALS ON THE AGENDA AT THE TRI-ANNUAL MEETING. Because the affirmative vote by the holders of a majority of the outstanding Common Units is needed to adopt the Exchange and the Exchange-Related Amendments about which we have previously written to you, your failure to vote will have the same effect as a vote "AGAINST" the adoption of those proposals. YOUR BOARD OF SUPERVISORS RECOMMENDS YOU VOTE "FOR" THE EXCHANGE AND THE EXCHANGE-RELATED AMENDMENTS FOR THE FOLLOWING REASONS: o Unitholders will receive the benefit of 100% of all future distribution growth opportunities. o The Exchange will simplify our capital structure and lower our future cost of equity capital in support of our long-term growth strategies. o The General Partner's Incentive Distribution Rights and economic interest in Suburban and its operating partnership subsidiary will be eliminated in exchange for approximately 7% of the total Common Units to be outstanding. o Unitholders will have the right to elect all Supervisors o The interests in Suburban of our senior management will be entirely in the form of Common Units. YOUR VOTE IS EXTREMELY IMPORTANT NO MATTER HOW MANY UNITS YOU OWN! Please save your Partnership the expense of additional follow-up mailings by voting "FOR" ALL PROPOSALS TODAY by telephone, the Internet or by signing, dating and returning the enclosed proxy card in the postage prepaid envelope provided to ensure that your vote is received in time to be voted at the Tri-Annual Meeting. Thank you for your cooperation. Very truly yours, Paul Abel General Counsel & Secretary ================================================================== IMPORTANT If you have any questions or need assistance voting your shares, please contact: INNISFREE M&A INCORPORATED Unitholders Call Toll Free: (877) 717-3930 Banks & Brokers Call Collect: (212) 750-5833 ==================================================================
