HOUSTON, Dec. 28, 2012 (GLOBE NEWSWIRE) -- ERHC Energy Inc. (OTCBB:ERHE), a publicly traded American company with oil and gas assets in Sub-Saharan Africa, today announced that the Company has commenced its previously announced rights offering. Upon the effectiveness at the close of business yesterday of ERHC's prospectus supplement filed with the Securities and Exchange Commission with respect to the rights offering, ERHC distributed on a pro rata basis to the holders of its common stock one non-transferable subscription right for every three shares of common stock owned as of the close of business on the previously announced December 17, 2012 record date. Each subscription right (with the total number of subscription rights issuable to a holder rounded down to avoid the issuance of fractional rights) entitles its holder to purchase one share of the Company's common stock at a subscription price equal to $0.075 per share. In addition, holders of subscription rights who fully exercise all of their subscription rights may also request to purchase additional shares of the Company's common stock that remain unsubscribed at the expiration of the rights offering, subject to the availability and pro rata allocation of shares among rights holders exercising such over-subscription right. The Company will offer up to an aggregate of 246,486,285 shares of its common stock in the rights offering, inclusive of the over-subscription privileges, representing approximately 33 percent of its current outstanding shares of common stock, if fully subscribed. The rights offering will terminate at 5:00pm, central time, on January 31, 2013, unless extended. Holders of rights will need to exercise their subscription rights prior to that time and date. The Company plans to apply capital raised in the rights offering to fund specific exploration and development activities pursuant to work programs governing its exploration acreage in the Republics of Chad and Kenya, as well as for general corporate purposes and working capital needs.
