Syntroleum Synthetic Fuels Showcased at North American International Auto Show

    DETROIT, Jan. 5 -- "In our view, the most exciting thing at
this year's Auto Show isn't a car, it's what's inside," said Mark Agee,
President of Syntroleum Corporation .  A Tulsa, Oklahoma-based
energy technology company, Syntroleum is the developer of the designer fuels
being showcased by DaimlerChrysler in its Dodge Power Wagon
concept car at this week's 1999 North American International Auto Show in
Detroit.
    Syntroleum's fuel, produced using the company's proprietary process for
converting natural gas into synthetic liquid hydrocarbons, contains no sulfur
or aromatic molecules, the components of conventional petroleum-based fuels
that create emissions problems in conventional diesel engines.  The fuel also
has the advantage of being able to run in today's vehicles without
modification, as well as the ability to be distributed through today's
existing pipelines and gas stations.
    "We are very pleased to be working with DaimlerChrysler to explore the
potential for our synthetic fuel technology to provide an abundant source of
clean, affordable and higher-performing fuels for the future," said Mr. Agee.
"We have been very impressed with their commitment to cleaner and more
efficient engine technology, as well as their obvious technical expertise."
In October, Syntroleum and Chrysler signed an agreement to jointly develop
designer fuels, lubricants and automatic transmission fluids using the
Syntroleum Process.
    In addition to producing synthetic transportation fuels, lubricants and
other specialty products, Syntroleum's GTL technology offers a number of other
potential benefits for the environment and economic development.  These
include:

    --  alleviating the need for flaring natural gas, which is believed to
        contribute to global warming and has been outlawed in a number of
        countries; and

    --  helping to meet increasingly stringent environmental standards and the
        requirements of the 1992 Energy Policy Act, which requires the federal
        government and many large cities to convert an increasing percentage
        of their transportation fleets to alternative fuels.

    Syntroleum licenses its proprietary process for converting natural gas
into synthetic crude oil and transportation fuels.  Current licensees include
Texaco, ARCO, Marathon Oil, Kerr-McGee, ENRON and YPF.
    This document includes forward-looking statements as well as historical
information.  Forward-looking statements include, but are not limited to,
statements relating to the testing, certification, characteristics
and use of synthetic fuels and alternative fuels, the Syntroleum Process and
related technologies and products, GTL plants based on the Syntroleum Process
(including the development of planned plants), the economic use of such plants
and the continued development of the Syntroleum Process.  When used in this
document, the words "anticipate," "believe," "estimate," "expect," "intent,"
"may," "project," "plan," "should," and similar expressions are intended to be
among the statements that identify forward-looking statements.  Although
Syntroleum believes that its expectations reflected in these forward-looking
statements are reasonable, such statements involve risks and uncertainties and
no assurance can be given that actual results will be consistent with these
forward-looking statements. Important factors that could cause actual results
to differ from these forward-looking statements include the potential that
commercial-scale GTL plants will not achieve the same results as those
demonstrated on a laboratory or pilot basis or that such plants will
experience technological and mechanical problems, the potential that
improvements to the Syntroleum Process currently under development may not be
successful, the impact on plant economics of operating conditions (including
energy prices), competition, intellectual property risks, Syntroleum's
ability to obtain financing and other risks described in the company's filings
with the Securities and Exchange Commission.
