ADDENDUM ("Licensed Unit"); and
WHEREAS, CHEVRON RESEARCH is interested in supporting a long-term second
commercial demonstration of the AROMAX process in Licensed
<PAGE> 2
Unit processing only Demonstration Feed in a multi-reactor system with at least
one full catalyst regeneration; and
WHEREAS, SOUTH HAMPTON as CHEVRON RESEARCH's first non-affiliated licensee is
willing to carry out a long-term commercial demonstration meeting CHEVRON
RESEARCH's objectives on the terms and conditions set forth in this ADDENDUM;
NOW, THEREFORE, in consideration of the premises and covenants herein, CHEVRON
RESEARCH and SOUTH HAMPTON agree as follows:

ARTICLE 2-0 TECHNICAL ASSISTANCE
2.1 In order to support the Long-Term Demonstration of the AROMAX Process in
Licensed Unit, Licensed Unit must be modified by the addition of AROMAX
Equipment and new AROMAX Catalyst must be installed in Licensed Unit. In
addition, since Licensed Unit will not provide the estimated hydrogen
requirements for SOUTH HAMPTON's hydrotreating operations at the Refinery,
based upon SOUTH HAMPTON's planned expansion of such operations, it will be
necessary to return the Rheniforming Unit to service. Accordingly, as part
of the Long-Term Demonstration contemplated by this ADDENDUM, the
Rheniforming Unit must be modified by the addition of Rheniforming
Equipment and new Rheniforming F Catalyst must be installed in the
Rheniforming Unit. CHEVRON RESEARCH and SOUTH HAMPTON agree that the
relative responsibilities and obligations of the parties during the
Long-Term Demonstration relating to assistance during pre-startup, startup,
normal, and regeneration operations for Licensed Unit and for the
Rheniforming Unit shall be as follows:
2.1.1 (Pre-Startup) CHEVRON RESEARCH will specify the equipment
modifications required for the Long-Term Demonstration, and will
assist SOUTH HAMPTON to
-3-
<PAGE> 4
locate, inspect, and install AROMAX Equipment and Rheniforming
Equipment. Following installation and inspection of the AROMAX
Equipment and Rheniforming Equipment, CHEVRON RESEARCH will specify
cleanup and dryout procedures to ready Licensed Unit and the
Rheniforming Unit for catalyst loading, and will advise and assist
SOUTH HAMPTON during cleanup and dryout. CHEVRON RESEARCH will specify
and supply the initial charges of new AROMAX Catalyst, Rheniforming
Catalyst, and sorbents required for the Long-Term Demonstration and
will assist SOUTH HAMPTON during loading of such Catalysts and
sorbents. The extent of pre-startup assistance for Licensed Unit and
the Rheniforming Unit to be provided by CHEVRON RESEARCH will be
determined by CHEVRON RESEARCH as required to carry out the Long-Term
Demonstration after consultation with SOUTH HAMPTON. SOUTH HAMPTON
will be responsible for and will carry out pre-startup of Licensed
Unit and the Rheniforming Unit. CHEVRON RESEARCH will perform or have
performed cleanup of Licensed Unit for sulfur removal. When requested
by CHEVRON RESEARCH, SOUTH HAMPTON will provide reasonable assistance
during cleanup and dryout of Licensed Unit. CHEVRON RESEARCH will
reimburse SOUTH HAMPTON for the agreed actual out-of-pocket expenses
-4-
<PAGE> 5
incurred if SOUTH HAMPTON contracts with a third party approved by
CHEVRON RESEARCH for assistance during the cleanup, and will reimburse
SOUTH HAMPTON for the actual cost of any nitrogen purchased at CHEVRON
RESEARCH'S request during the initial dryout of Licensed Unit.
2.1.2 (Startup) The Rheniforming Unit will be returned to service before
starting up Licensed Unit. CHEVRON RESEARCH has previously provided
startup procedures for the Rheniforming Unit and will advise and
assist SOUTH HAMPTON during startup of the Rheniforming Unit. However,
SOUTH HAMPTON will be responsible for carrying out the startup,
including the supply of required feed and all chemicals. Following
startup of the Rheniforming Unit, SOUTH HAMPTON will startup Licensed
Unit with the advice and assistance of CHEVRON RESEARCH. Startup
procedures for Licensed Unit will be specified by CHEVRON RESEARCH.
CHEVRON RESEARCH will also specify the Demonstration Feed, the feed
rate(s), and operating conditions for Licensed Unit during startup.
The extent of startup assistance for Licensed Unit and the
Rheniforming Unit to be provided by CHEVRON RESEARCH will be
determined by CHEVRON RESEARCH as required to carry
-5-
<PAGE> 6
out the Long-Term Demonstration after consultation with SOUTH HAMPTON,
and will include full shift coverage during startup of Licensed Unit.
CHEVRON RESEARCH will reimburse SOUTH HAMPTON for the actual cost of any
nitrogen or electrolytic hydrogen purchased at CHEVRON RESEARCH's
request during startup of Licensed Unit.
2.1.3 (Operation) Operations of the Rheniforming Unit will be controlled by
and will be the sole responsibility of SOUTH HAMPTON. Rheniforming
Process operations will be carried out by SOUTH HAMPTON pursuant to the
terms and conditions of the "Agreement Relating to Rheniforming Process"
dated May 16, 1978, as supplemented and amended by subsequent written
agreements entered into by CHEVRON RESEARCH and SOUTH HAMPTON.
Operations of Licensed Unit during the Long-Term Demonstration will be
controlled by and will be the sole responsibility of SOUTH HAMPTON.
SOUTH HAMPTON will operate Licensed Unit during the Long-Term
Demonstration to process only Demonstration Feed under operating
conditions to be specified by CHEVRON RESEARCH. Feed rate(s) to Licensed
Unit will be specified by CHEVRON RESEARCH in consultation with SOUTH
HAMPTON. However, once established, feed rate
-6-
<PAGE> 7
will be held relatively constant for at least seven (7) days, and
subsequent changes will be limited to twenty-five percent (25%) of the
rate of the previous period, unless otherwise agreed to by CHEVRON
RESEARCH. At no time will the feed rate to Licensed Unit exceed 420
BPOD.
2.1.4 (Regeneration) At times specified by CHEVRON RESEARCH, SOUTH HAMPTON
will regenerate AROMAX Catalyst in Licensed Unit with the advice and
assistance of CHEVRON RESEARCH. AROMAX Catalyst regeneration procedures
will be specified by CHEVRON RESEARCH. CHEVRON RESEARCH will reimburse
SOUTH HAMPTON for the actual cost of any nitrogen or electrolytic
hydrogen purchased at CHEVRON RESEARCH's request during regeneration of
AROMAX Catalyst.
2.2 Neither CHEVRON RESEARCH nor SOUTH HAMPTON will be obligated to
compensate or reimburse the other for services performed or expenses
incurred as a result of the Long-Term Demonstration except as expressly
provided for in this Addendum.

ARTICLE 3-0 CATALYSTS AND SORBENTS
3.1 The initial charge of AROMAX Catalyst and sorbents for use in Licensed Unit
for the Long-Term Demonstration will be supplied by and delivered to the
Refinery by CHEVRON RESEARCH. CHEVRON RESEARCH will retain ownership and
risk of loss at all times. At the conclusion of the Long-Term Demonstration
CHEVRON RESEARCH will assist SOUTH HAMPTON to unload AROMAX Catalyst and
Sorbents and CHEVRON RESEARCH may then use and/or dispose of the AROMAX
Catalyst and sorbents in any manner without accounting to SOUTH HAMPTON.
3.2 The initial charge of Rheniforming Catalyst, not to exceed Two Thousand
(2,000) pounds, for the Rheniforming Unit will be supplied by and delivered
to the Refinery by CHEVRON RESEARCH. Title and risk of loss will pass to
SOUTH HAMPTON upon delivery to the Refinery gate. Rheniforming Catalyst
supplied hereunder, upon transfer of title to SOUTH HAMPTON, will be deemed
subject to the terms and conditions of the "Rheniforming Catalyst Supply
Contract", dated May 6, 1978 entered into by CHEVRON RESEARCH and SOUTH
HAMPTON. Accordingly, SOUTH HAMPTON will not resell or otherwise transfer
ownership, possession, or control of any portion of Rheniforming Catalyst
without CHEVRON RESEARCH's prior written approval.

<PAGE> 9
3.3 Licensed Unit presently contains Rheniforming Catalyst which will be
removed during pre-startup in order to convert to the practice of the
AROMAX Process for the Long-Term Demonstration. SOUTH HAMPTON owns such
Rheniforming Catalyst and will deliver same to CHEVRON RESEARCH at the
Refinery gate immediately upon removal. Title and risk of loss will pass to
CHEVRON RESEARCH upon such delivery. CHEVRON RESEARCH may use and/or
dispose of the Rheniforming Catalyst acquired hereunder in any manner
without accounting to SOUTH HAMPTON.
