ERHC Company History

ERHC Energy, Inc. is focused on maximizing corporate value and shareholder returns by leveraging its assets in the Joint Development Zone (JDZ) between Sao Tome & Principe and Nigeria and in the exclusive waters of Sao Tome (EEZ) and by pursuing other upstream and downstream oil and gas opportunities wherever attractive projects can be acquired at low cost and transformed into valuable oil and gas assets. ERHC currently is partnering with other oil and gas companies that have technical and financial resources that can help ERHC fully exploit these assets.

1986-1997 – Early ERHC History

ERHC Energy was formed in 1986 as a Colorado corporation that operated in a number of business areas. In 1996, ERHC narrowed its focus and began operating solely as an energy investment company.

In May 1997, the ERHC entered into an exclusive joint venture with the Democratic Republic of Sao Tome & Principe (DRSTP) (the “1997 Agreement”).

1999 – JDZ Prospects/Leads Identified

A report issued by WesternGeco interpreted and mapped out seismic data, highlighted prospectivity and calculated volumetrics in the JDZ. The report identified 56 prospective structures within Blocks 1 to 9 in the JDZ – 17 prospects and 39 leads. The estimate of "recoverable reserves potential" is based on WesternGeco's report, which interpreted and mapped seismic data, highlighted prospectivity and calculated volumetrics. It did not include any attempt to comply with any SEC definition of reserves. ERHC Energy has access to the data under the terms of a data use license with WesternGeco.

2001 - Joint Development Zone Established

In the spring of 2001, the governments of Sao Tome & Principe and Nigeria reached an agreement over a long-standing maritime border dispute. Under the terms of the agreement, the two established the Joint Development Zone to govern commercial activities within the disputed boundaries.

About the JDZ:

• 200 km off the coastline of Nigeria and Sao Tome & Principe
• 34,548 sq km
• 1,500 meters deep in the northern part
• 3,500 meters deep at its southwestern sector.
• Adjacent to several large petroleum discovery areas

Oversight of the JDZ

The JDZ is administered by a Joint Development Authority (JDA) which oversees all future exploration and development activities in the JDZ. The remaining claimed territorial waters of Sao Tome & Principe are known as the Exclusive Economic Zone (EEZ).

Revenue Split

Revenues derived from the JDZ will be shared 60/40 between the governments of Nigeria and Sao Tome and Principe, respectively.

2001 – A New Agreement/New Exploration Rights

On May 21, 2001, the 1997 Agreement was replaced by a Memorandum of Agreement (the “2001 Agreement”), which was embodied in a Consent Award issued by an international arbitrator as a result of the satisfaction of several conditions, including the ratification of a treaty between the FRN and the DRSTP. The 2001 Agreement gave ERHC exploration and production rights in the EEZ and the JDZ.

2003 – Option Agreement

In April 2003, ERHC and DRSTP entered into an Option Agreement (the “2003 Option Agreement”) in which ERHC relinquished certain financial interests in the JDZ in exchange for exploration rights in the same area.

The NSAI report estimated ERHC risked prospective resources in JDZ Blocks 2, 3 and 4 totaled 135.5 million barrels of oil and 144 billion cubic feet of natural gas (P50).
