RE:  SHAREHOLDERS  AGREEMENT  DATED  3RD  AUGUST  1998
- ------------------------------------------------------

Pursuant  to a Shareholders Agreement dated 3rd August 1998, ARCO and Triton are
shareholders  of  Triton  International  Oil Corporation.  Triton Oil Company of
Thailand  and  Triton  Oil  Company  of  Thailand (JDA) Limited are wholly owned
subsidiaries  of  Triton  International  Oil  Corporation.

Reference  is made to the recent discussions regarding the imminent signature of
the  Gas  Sales  Agreement.  As  shareholders  of  Triton  International  Oil
Corporation,  ARCO and Triton wish to record their agreement to the following to
supplement  the  Shareholders  Agreement  as  follows:

1.     Unless otherwise defined in this Agreement, capitalized terms used herein
shall  have  the  same  meanings  as  the definitions specified in the Gas Sales
Agreement  between Malaysia-Thailand Joint Authority and Petronas Carigali (JDA)
Sdn., Bhd. and Triton Oil Company of Thailand and Triton Oil Company of Thailand
(JDA)  Limited  as  Sellers  and the Buyers for the Supply of Gas from the Block
A-18  of  the  Malaysia-Thailand  Joint  Development  Area  (the  "Gas  Sales
Agreement").

2.     Subject to the terms and conditions herein, in the event there is a delay
to  the DCD caused by a delay in obtaining the EIA Approval, Triton shall pay to
ARCO an amount equal to one million two hundred and fifty thousand United States
dollars (US$1,250,000.00) for every whole calendar month that the DCD is delayed
after  the  EPC30  Date. The EPC30 Date is the date thirty (30) months after the
engineering,  procurement and construction contract for the Cakerawala Gas Field
Development  is  awarded.  These payments shall be capped at a maximum of thirty
million  United  States  Dollars  (US$30,000,000.00).

3.     In its capacity of shareholder of a Seller under the Gas Sales Agreement,
ARCO confirms that it will continue to act in good faith and in a diligent, safe
and efficient manner in accordance with good and prudent oil field practices and
conservation  principles  generally  followed  by  the  international  petroleum
industry  under  similar  circumstances  in proceeding with the construction and
installation  of  facilities  enabling the production and delivery of gas to the
Buyers  in  order  to  meet  with  Buyers'  timing  of  first  gas  delivery.

4.     Where  a payment by Triton to ARCO is due under this Agreement, ARCO will
issue  demand notices on a monthly basis.  Triton will make such payments within
thirty (30) days following the demand notices issued by ARCO by wire transfer of
immediately  available  funds  to  an  account  specified  by  ARCO.

5.     No  variation  of this Agreement shall be effective unless in writing and
signed  by  or  on  behalf  of  each  of  the  Parties.

6.     This Agreement may be entered into in any number of counterparts, each of
which  when executed and delivered shall be an original but all the counterparts
together  shall  constitute  one  and  the  same  instrument.

7.     This  Agreement  shall  be  governed  by and construed in accordance with
English  law,  excluding  any  conflict of laws principles which would apply the
laws  of  another  jurisdiction.

8.     The  parties irrevocably agree that any disputes in relation hereto shall
be  submitted to binding arbitration in London conducted in the English language
in  accordance  with  the  arbitration  rules  of  the  International Chamber of
