Other Events. On December 14, 2004, Unocal Corporation ("Unocal") announced by press release that its wholly owned Union Oil Company of California subsidiary reached a final settlement with Agrium Inc. and Agrium U.S. ("Agrium") of all claims arising from litigation regarding the natural gas sales to Agrium's Kenai, Alaska, fertilizer plant and the original sale of that plant to Agrium by Unocal. Under the settlement, all litigation between the companies will be dismissed with prejudice. As part of the settlement, Unocal and Agrium have entered into a new gas sales agreement, which is effective December 1, 2004, with defined monthly gas delivery obligations that terminate on October 31, 2005. Unocal produces natural gas from fields in south Alaska and sells that gas to the Agrium plant as well as to other customers. Agrium purchased the fertilizer plant from Unocal in 2000. The Purchase and Sales Agreement ("PSA") for that transaction continues in effect after the settlement. Under the settlement agreement, Unocal will pay Agrium a net amount of $25 million for early termination of the existing gas sales agreement (which originally ran until June 2009), full release of Unocal of all environmental claims, and resolution of all other issues, including certain contingent payments due Unocal under the PSA. The settlement payment is in addition to the remaining liquidated damages due under the existing sales agreement. Unocal expects to record a $15 million after-tax charge to earnings in the fourth quarter 2004 as a result of the settlement. This filing contains forward-looking statements about matters relating to Unocal's settlement of its dispute with Agrium. Although these statements are based upon Unocal's current expectations and beliefs, they are subject to known and unknown risks and uncertainties that could cause actual results and outcomes to differ materially from those described in, or implied by, the forward-looking statements, including any future disagreements with Agrium regarding the Kenai, Alaska, fertilizer plant; and other factors discussed in Unocal's 2003 Annual Report on Form 10-K, as amended, and subsequent reports filed by Unocal with the Securities and Exchange Commission (SEC File No. 1-8483).
