NewsReal Please Post Promptly Keep posted through 4/28 Good morning... This is Friday, April 28, 2000 - -------------------------------------------------------------------------------- Reminder: Annual Stockholders Meeting is May 18; Voting Deadline for ESOP Participants is May 14 - -------------------------------------------------------------------------------- The UAL Corporation annual stockholders meeting this year will be held in Chicago May 18. The meeting will take place in the auditorium on the 8th floor of Harris Trust and Savings Bank at 111 West Monroe Street. It is scheduled for 10 a.m., local time. Among the issues stockholders are voting on this year is a proposal for amendments to the company's charter. The amendments would allow ESOP participants to receive any dividend paid on UAL's common stock in the same manner as public stockholders. The board of directors publicly announced in November 1999 its intention to start the proposed dividend program, contingent on the outcome of the charter vote. Detailed information on the vote is included in the proxy materials sent to employees who are ESOP participants or UAL stockholders. United's U.S. ESOP participants may attend the stockholders meeting, but they are not eligible to vote at the meeting. Instead, U.S. ESOP participants who are eligible to vote must cast their votes by 12 midnight (Central Daylight Time) on May 14, 2000, in order for their votes to be counted. (Eligible ESOP participants are U.S. participants who have owned UAL stock through the ESOP on or before March 20, 2000.) Eligible participants can cast their votes by Internet, telephone or mail. Detailed instructions for these methods are included in the proxy package. Public stockholders can vote on the Internet, by telephone, by returning a proxy voting card in the mail, or by voting at the annual stockholders meeting. If you have not yet received your proxy materials, please call Harris Bank at 1-800-647-4488 to request a replacement. - --------------------------------------------------------------------------------
