       GIANT INDUSTRIES, INC., AND HOLLY CORPORATION
                       CANCEL MERGER

Scottsdale, Arizona, September 1, 1998   Giant Industries,
Inc., (NYSE:GI) and Holly Corporation (ASE: HOC) announced
today that the two companies have mutually agreed to terminate
their proposed merger.  The Federal Trade Commission expressed
concerns relative to the possible impact of a merger on
portions of the market.  The companies disagreed with these
concerns, but diligently negotiated with the FTC.  They were,
however, unable to reach a solution satisfactory to the
companies.  In addition, various other considerations weighed
in this decision by the companies, including the uncertainty
caused by a lawsuit filed by Longhorn Partners Pipeline against
Holly.

Giant's Chairman and CEO Jim Acridge commented, "We are
disappointed that we were unable to complete this merger. 
Together with Holly, we have worked diligently over the past
four months to successfully resolve the issues with the FTC,
but could not find a solution that we felt was in the best
interest of our stockholders."  Acridge continued, "We are
looking forward to concentrating on our core businesses and
taking advantage of a number of recent changes in our market
area.  Giant, as a net buyer of gasoline and diesel fuel, is in
a unique position to take advantage of these changes."

Giant Industries, Inc., a refiner and marketer of petroleum
products, has reported revenues of $657 million and net
earnings of $15.3 million for fiscal year 1997.  Giant owns and
operates two New Mexico crude oil refineries, a 260 mile crude
