ERHC Signs Participation Agreement with Noble Energy

Environmental Remediation Holding Corporation has signed a participation agreement with Noble Energy whereby the companies will jointly evaluate and negotiate participation in Block 4 of the Nigeria/Democratic Republic of Sao Tome and Principe Joint Development Zone ("JDZ") in the Gulf of Guinea, offshore West Africa.

This will continue Noble's recent expansion in West Africa and should complement its successful activities in Equatorial Guinea. Noble's successes in production and marketing of natural gas, condensate and gas utilization give it additional flexibility in evaluating and monetizing hydrocarbon discoveries.

Mr. Ali Memon, president and CEO of ERHC, said today: "Noble's experience and superior performance in deep water and participation in record setting offshore operations are factors that make Noble an excellent choice for ERHC."
