Tulsa, OK--Syntroleum Corporation (NASDAQ: SYNM) announced that stockholders
reelected directors Alvin R. Albe, Jr. and J. Edward Sheridan to the Board of
Directors to hold office for terms to expire in the year 2002 at it's Annual
Stockholders' Meeting today. Mr. Albe has served as a board member since
December 1988 and Mr. Sheridan has served since November 1995.  Continuing board
members are Messrs. Kenneth L. Agee, Mark A. Agee, Frank M. Bumstead, P. Anthony
Jacobs, Robert Rosene, Jr. and James R. Seward. The meeting was held at the
company's corporate headquarters in Tulsa, Oklahoma.

Stockholders also approved the proposal to reincorporate Syntroleum as a
Delaware corporation and ratified the appointment of Arthur Anderson LLP as
independent public accountants for Syntroleum for the year ending December 31,
1999.

Kenneth L. Agee, Chairman and CEO reported that 1998 had been a pivotal year for
Syntroleum as a result of becoming a public company, weathering the decline in
oil prices, and establishing a number of key technology development programs.
He indicated that the company has made substantial progress during the past
year, citing the company's success in attracting outstanding engineering and
scientific professionals as the major driver.  He went on to say that 1999 could
see accelerated development of gas-to-liquids projects as a result of the recent
increase in oil prices and intensified interest in bringing clean fuels to
market.

This document includes forward-looking statements as well as historical
information. Forward-looking statements include, but are not limited to,
statements relating to the development of gas-to-liquids projects and interest
in clean fuels. 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.
