QUESTAR BOARD DECLARES 226TH CONSECUTIVE DIVIDEND
WITHOUT A REDUCTION
Questar Recognized as ‘Dividend Achiever'

SALT LAKE CITY — Questar Corp.'s (NYSESTR) board of directors today approved a $.175 (17.5cent) quarterly common stock dividend. The dividend — payable June 18, 2001, to shareholders of record on May 25, 2001 — is the same as the previous quarter's and onehalf cent higher than a year earlier (17 cents). This is the company's 226th consecutive dividend without a reduction. 

Questar also is among only 3 percent of U.S.–based companies recognized as a "Dividend Achiever"— a company that has increased its dividend payments over the past 10 consecutive years. Year 2000 marked the 21st consecutive year in which Questar increased its dividend.

The company is profiled in Mergent FIS's "Handbook of Dividend Achievers, 2001 Edition," a reference guide for investors seeking companies that deliver increasing dividend payments. Of the 10,000 U.S.–based firms tracked by the company, about 290 met its criteria for recognition. For a company to be included, its stock must be actively traded on the New York Stock Exchange, Nasdaq's National Market or the American Stock Exchange. The list is based on the premise that certain equity investments can provide a rising cash return over the long run while offering the additional benefit of potential price appreciation.

Headquartered in Salt Lake City, Questar Corp. is a diversified energy company with $2.5 billion in assets. Through subsidiaries, it engages in energy development and production; gas gathering and processing; wholesale gas, electricity and liquids trading; retail energy services; interstate gas transmission and storage; retail gas distribution; and information systems and technologies.
