Kosmos Energy Ltd. (“Kosmos”) (KOS) announced today that, subject to market conditions, it intends to offer an additional $225 million aggregate principal amount of senior secured notes due 2021 in a private offering to eligible purchasers as a non-fungible add-on to the existing $300 million aggregate principal amount of such notes currently outstanding (the “existing notes”). The notes will have identical terms as the existing notes, other than the date of issue, the initial price, the first interest payment date and the first date from which interest will accrue. Kosmos intends to use the net proceeds from this offering to repay a portion of the outstanding indebtedness under its commercial debt facility and for general corporate purposes.

The securities to be offered have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws and unless so registered, the securities may not be offered or sold in the United States without registration or an applicable exemption from the registration requirements of the Securities Act and applicable state securities or blue sky laws and foreign securities laws. The add-on senior secured notes and the related guarantees will be offered only to qualified institutional buyers in reliance on the exemption from registration set forth in Rule 144A under the Securities Act, and outside the United States, to non-U.S. persons in reliance on the exemption from registration set forth in Regulation S under the Securities Act.

This press release is being issued pursuant to, and in accordance with, Rule 135c under the Securities Act, and is neither an offer to sell nor a solicitation of an offer to buy the notes or any other securities and shall not constitute an offer to sell or a solicitation of an offer to buy, or a sale of, the notes or any other securities in any jurisdiction in which such offer, solicitation or sale is unlawful.
