Issuer GP, continues to serve as a director of the Issuer GP. Four of the six vacancies created by these resignations were filled at the Closing through the appointment of individuals affiliated with the MDP Entities and certain of the C/R Entities.
In addition, on July 21, 2003, Mark G. Papa, an independent director as defined by the NYSE and the SEC, was appointed to the board of directors of Issuer GP. On November 7, 2003, at the annual meeting of Unitholders, one of the directors affiliated
with the MDP Entities and one of the directors affiliated the C/R Entities were re-elected to the board of directors of Issuer GP. On November 21, 2003, the board of directors elected James R. Montague as an independent board member. As soon as
practicable, the Issuer GP intends to expand the size of the board to eight members and appoint one additional director who satisfies the &#147;independence&#148; requirements of the NYSE and the SEC. Most of the pre-Acquisition executive officers
of the Issuer GP have continued in those capacities following the Acquisition.</FONT></TD></TR>
