ERHC Energy Reaches Agreement With Kosmos for Block 11, Sao Tome and Principe EEZ

HOUSTON, TX--(Marketwired - Oct 20, 2015) - ERHC Energy Inc. (OTC PINK: ERHE), a publicly traded American company with oil and gas assets in Sub-Saharan Africa, announced today that it has reached an agreement with Kosmos Energy (NYSE: KOS), a leading independent oil and gas exploration and production company focused on frontier and emerging areas to transfer all ERHC's rights to Block 11 of the São Tomé and Principe Exclusive Economic Zone (EEZ) to Kosmos. The agreement has been approved by the National Petroleum Agency of Sao Tome & Principe ("ANP-STP") as required in the requisite Production Sharing Contract ("PSC") for EEZ Block 11.

"Given the difficult global environment for doing deals, particularly for deep-offshore assets in frontier areas, we are very pleased to have concluded the agreement with Kosmos," said ERHC President and CEO Peter Ntephe. "The agreement enables us to immediately monetize one of our offshore holdings while preserving a financial upside in the event that exploration in Block 11 is successful."

ERHC retains 100 percent of the rights to EEZ Block 4 as well as the option to take up to a 15 percent working interest in each of two other unlicensed EEZ blocks of its choice. ERHC and the ANP-STP have agreed in principle to terms of a PSC for Block 4. In Kenya, ERHC holds a 35 percent interest in Block 11A, where the first exploration well is expected to be spudded toward the end of the first quarter of 2016. In Chad, ERHC is accepting tender proposals for a 2-D seismic acquisition program for Block BDS 2008.

ERHC also has interests across several oil blocks in the Nigeria -- São Tomé and Príncipe Joint Development Zone (JDZ).
