Other Events. McMoRan Exploration Co. (McMoRan) announced today the following oil and gas exploration alliance: Today we announced that we have entered into an alliance with Samedan Oil Corporation, a wholly owned subsidiary of Noble Affiliates, Inc. to conduct exploration on our oil and gas acreage in the Gulf of Mexico. Samedan has committed to participate with a 25 percent working interest in six of seven specified prospects as shown in the table below. In addition, Samedan has agreed to work with us in identifying additional future prospects from the acreage position accumulated by us in our previously announced transactions with Shell Offshore Inc. and Texaco Exploration and Production Inc. and Samedan has the right to participate in future prospects. Following are the seven specified prospects with approximate ownership interests: Prospect location (offshore blocks) McMoRan Samedan ---------------------------------- ------------ ------------ WI(1) NRI(1) WI(2) NRI(2) ----- ------ ----- ------ Vermilion 195/196/207 47.5% 34.2% 25.0% 18.0% Eugene Island 96/97/109 - shallow 38.0% 27.4% 25.0% 18.0% Eugene Island 96/97/109 - deep 46.3% 33.2% 25.0% 17.9% Vermilion 144/145 71.3% 57.2% 25.0% 20.1% West Delta 1/12/13/Grand Isle 2 47.5% 32.1% 25.0% 16.9% Louisiana State Lease 340 (portions) 30.4% 23.9% 25.0% 19.6% Garden Banks 272(3) 71.3% 51.3% 25.0% 18.0% (1) Reflects minimum estimated working interests (WI) and net revenue interests (NRI), assuming participation election by others, except that the Halliburton Company right to participate is not included. Halliburton has the right to participate by paying 20 percent of our acquisition, exploration and development costs and receiving 20 percent of our net revenues until payout, after which Halliburton receives 6 percent of our interest. (2) Samedan will share costs on a disproportionate basis to earn these WIs and NRIs. (3) Prospect under evaluation. We have not yet committed to drill an initial test well on this lease. If drilled, Samedan has the option to participate. The Shell and Texaco transactions provide us exploration rights to an aggregate of approximately 660,000 acres on 145 blocks in the Gulf of Mexico from coastal water depths up to 2,200 feet, with a majority in water depths less than 400 feet. In the Shell transaction, we purchased Shell's interest in 56 blocks in the Gulf of Mexico for $37.7 million in cash and Shell retained a one-twelfth overriding royalty interest. In the Texaco transaction, we acquired exploration rights on 89 blocks in the Gulf of Mexico and agreed to spend $110 million on exploration through June 30, 2003. Texaco retained rights to participate on varying terms. Samedan's share of estimated costs for the specified exploration projects is approximately $25 million. This Samedan commitment ensures our $50 million in current availability under a bank credit facility which is guaranteed by Halliburton and secured by our producing properties. No amounts are currently outstanding under this facility. Under our alliance with Halliburton, an integrated team of McMoRan, Halliburton and McMoRan contractor personnel has been established to conduct our exploration, development and production activities and Halliburton services are used in these activities when applicable. We are obligated to raise specified levels of additional capital by December 31, 2000 and 2001. The commitment by Samedan, together with $50 million raised by us in a common stock offering in April 2000, will serve to substantially fulfill the December 31, 2000 obligation. In addition, Halliburton has an option to participate in our interests in the development of our exploration discoveries.
