Item  1.02.       Termination of a Material Definitive Agreement.

      In September 2004, the Company entered into a Participation Agreement with
Noble Energy whereby the companies jointly applied for rights in the production
sharing contract for Block 4 of the Joint Development Zone. In May 2005, the
Nigeria-Sao Tome and Principe Joint Development Authority ("JDA") awarded the
ERHC/NOBLE consortium 35 percent interest in Block 4. Noble informed the JDA and
ERHC Energy of its decision to withdraw from participating in Block 4 and from
the ERHC / Noble consortium on October 24, 2005. The Company was informed by the
JDA on October 26, 2005 that it was sorry that the Noble/ERHC consortium was
unable to accept the award of Block 4.

      On October 25, 2005, ERHC entered into a memorandum of understanding with
Addax Petroleum and the parties are currently negotiating a participation
agreement. The memorandum of understanding has been submitted to the JDA
requesting that Addax Petroleum replace Noble in the Noble/ERHC consortium.
