                   SLH CORPORATION ANNOUNCES MERGER APPROVAL


     SHAWNEE MISSION, KS - SLH Corporation (SLH) announced that both SLH and 
Syntroleum (R) Corporation stockholders voted to approve the merger between SLH 
and Syntroleum.  The merger is expected to become effective on August 7, 1998.

     In the merger, each share of Syntroleum common stock not presently owned by
SLH will be exchanged for 1.2899 shares of SLH common stock, the name of SLH 
will be changed to "Syntroleum Corporation", and SLH management and six of the 
eight SLH directors will be replaced with Syntroleum management and directors.  
P. Anthony Jacobs, Chairman of SLH, and James R. Seward, President and CEO of 
SLH, who are currently directors of both companies, will remain as directors of 
the merged company.

     Approximately 16,825,000 shares of common stock are to be issued pursuant 
to the merger, resulting in approximately 26,900,000 shares of SLH common stock 
issued and outstanding.  Although the merger will effect a change in the name of
SLH to "Syntroleum Corporation," certificates evidencing shares of SLH common 
stock prior to the merger that bear the name "SLH Corporation" will continue to 
evidence the same number of shares of SLH common stock after the merger.  
However, holders of SLH certificates may obtain new certificates that bear the 
name "Syntroleum Corporation" by delivering the old certificates to SLH's 
transfer agent together with appropriate transmittal documents that may be 
obtained from the transfer agent upon request.  SLH's transfer agent is American
Stock Transfer & Trust Company, 40 Wall Street, 46/th/ Floor, New York, NY 
10005, and the telephone number is (718) 921-8200.

     The common stock of the newly merged company is expected to begin trading 
on the National Market System of Nasdaq on Monday, August 10 under the symbol 
"SYNM".

 (R)Syntroleum is both a service mark and trademark of Syntroleum Corporation.
