INTERNAL BULLETIN To: All employees From: Chuck Williamson June 10, 2005 FTC ACCEPTS CHEVRON-UNOCAL CONSENT ORDER Today we reached a key milestone on our path to merging with Chevron. The U.S. Federal Trade Commission (FTC) has accepted a consent order for public comment, setting the stage for final regulatory clearance and completion of the transaction. Both companies worked closely with the FTC to address any concerns and help the regulatory process advance swiftly. The single issue raised by the FTC revolved around Unocal's patents for reformulated gasoline. We agreed to dedicate the remaining term of the patents to the public following completion of the merger. The next critical step in the approval process is for Unocal stockholders to vote on the transaction. The U.S. Securities and Exchange Commission is presently reviewing the preliminary registration statement that was filed on May 26. Once the SEC provides final clearance, we will deliver a proxy statement to our stockholders and schedule a special stockholders meeting to vote on the merger. Once the merger closes, we expect the integration of Unocal with Chevron to proceed quickly and smoothly. Our Integration Management Team (IMT) has been working diligently to ensure an efficient transition, with careful consideration of those involved. Chevron views the merger as an event that will significantly enhance its position as a leading global energy provider and partner-of-choice. Chevron also sees this transaction as an opportunity to expand its organizational capabilities with personnel from Unocal's skilled workforce. Although we are progressing quickly in our planning to become one company, we need to remember that until the transaction is completed, Chevron and Unocal are competitors and must operate as individual companies. We must continue to carefully manage the exchange of information by, through and with the guidance of the IMT. While some of you are involved with the integration efforts, most of you should be focused on your current job and helping advance our business priorities and objectives. Above all, your continued focus on safe operations is of paramount importance. Below is the news release that was issued jointly by Unocal and Chevron today. NEWS RELEASE FEDERAL TRADE COMMISSION ACCEPTS CHEVRON'S ACQUISITION OF UNOCAL SAN RAMON, Calif., June 10, 2005 - The Federal Trade Commission has notified Chevron Corporation and Unocal Corporation that Chevron's plans to acquire Unocal have been accepted by the commission, pending public comment. The FTC acceptance followed an agreement by Chevron, Unocal and FTC staff to settle litigation issues relating to Unocal's U.S. reformulated gasoline patents. Following completion of the acquisition, Chevron has agreed to dedicate to the public the remaining term of the patents and not to assert or enforce the patents to recover fees, royalties or damages. Reformulated gasoline is an environmentally-friendly fuel that is sold in selected U.S. cities to reduce smog levels. Details of the FTC decision and order are posted at www.ftc.gov. "The patent settlement is a positive step for America's gasoline consumers," said David O'Reilly, chairman and chief executive officer of Chevron. "It will eliminate expensive litigation over the patents and reduce the costs of producing reformulated gasoline, which is sold in many parts of the U.S." The next step in the approval process is a review of the preliminary Form S-4 filed by Chevron on May 26 with the U.S. Securities and Exchange Commission (SEC). The Form S-4 is a registration statement necessary to issue the shares of Chevron common stock that are part of the merger consideration. The registration statement contains a proxy statement for the special meeting of Unocal stockholders to vote on the merger. After the SEC completes its review of the Form S-4, Unocal will print and mail the final proxy statement to stockholders, scheduling a special stockholder meeting for a vote by Unocal stockholders on the terms of the acquisition. Chevron Corporation is one of the world's leading energy companies. With more than 47,000 employees, Chevron subsidiaries conduct business in approximately 180 countries around the world, producing and transporting crude oil and natural gas, and refining, marketing and distributing fuels and other energy products.
