TAMPA, Fla., June 14, 2013 (GLOBE NEWSWIRE) -- Odyssey Marine Exploration, Inc. (Nasdaq:OMEX), a pioneer in the field of deep-ocean shipwreck and offshore mineral exploration, has received $10 million from the early exercise of an option held by Mako Resources, LLC, an independent investment group, to purchase eight million shares of Oceanica Resources, S. de R.L. owned by Odyssey. Mako was granted the option in connection with Mako's earlier purchase of 15 million shares of Oceanica Resources from Odyssey in February 2013. The option exercise price of $1.25 per share, discounted from the original exercise price of $2.50 per share in order to facilitate this transaction, represents a 25% value increase over the price Mako paid for the Oceanica shares purchased in February 2013. Mako continues to hold the option to purchase an additional seven million shares of Oceanica at $2.50 per share at any time on or before December 31, 2013. As part of the company's strategy to maintain a control position in Oceanica, in parallel with the early exercise, Odyssey has also reached an agreement to purchase one million shares of Oceanica from another Oceanica shareholder at $1.25 per share in a transaction that provides a one-year option to purchase an additional one million shares at $2.50 per share. This transaction also grants Odyssey voting rights on an additional three million shares of Oceanica held by such other Oceanica shareholder so long as there is no change in control of Odyssey. The net effect of these transactions is that Odyssey will ultimately incur less dilution of its Oceanica ownership than originally anticipated under the initial stock sale agreement with Mako and Odyssey will now be able to effectively maintain voting control in the entity. Assuming all options are exercised and based on the total number of shares currently outstanding, Odyssey would own 49.6 percent of Oceanica with voting rights on a total of 52.6 percent of the shares.
