WHEREAS  Article  8.5(b)  of  the  Principal  Contract provides that recovery by
Contractors  of  allowable  costs expended in a Quarter for the Contract Area in
relation  to  Petroleum Operations in respect of Natural Gas shall be allowed up
to  a  maximum  of  fifty  per  cent  (50%)  of  such  costs;

AND  WHEREAS  CARIGALI,  TRITON  AND  TRITON JDA (hereinafter referred to as the
"Contractors") requested MTJA's agreement to an increase to sixty per cent (60%)
in  the  maximum  allowable  cost  to  be  recovered under Article 8.5(b) of the
Principal  Contract  for  certain  costs, in relation to past cost for Petroleum
Operations  in Block A-18 (sunk cost) and cost for development of the Cakerawala
Gas  Field, expended by Contractors for the purpose of assisting the development
of  the  Cakerawala  Gas  Project;

AND  WHEREAS  MTJA  agrees to the request of the Contractors to provide for such
increase  in the maximum allowable cost to be recovered by Contractors to assist
in  the  development  of  the  Cakerawala  Gas  Project and thereby to amend the
Principal  Contract  to  provide  for  same.

NOW  THEREFORE  it  is  hereby  stipulated  and  agreed  as  follows:

1.     The  Parties agree that Article 8.5(b) of the Principal Contract shall be
revised  as  follows  :

"Up  to  a maximum of fifty per cent (50%) shall be applied in the manner herein
provided  for the purpose of recovery by Contractors of allowable costs expended
in  that  Quarter  for  the Contract Area in relation to Petroleum Operations in
respect  of  Natural  Gas,  provided,  however, that a maximum of sixty per cent
(60%)  shall  be  applied  only for the costs stipulated in (i) and (ii) below :

(i)     All  allowable  costs  expended  by Contractors in relation to Petroleum
Operations  in  Block  A-18  in  respect  of Natural Gas from the Effective Date
through  31  December 1997 as reported in the detailed audited accounts as of 31
December 1997, as may be amended, modified or supplemented, until such costs are
fully  recovered  by  Contractors;

(ii)     All  allowable  costs  expended by Contractors from and after 1 January
1998  in  relation  to  capital expenditures incurred for the development of the
Cakerawala  Field  including, without limitation, Cakerawala Booster Compression
and  Cakerawala  Platform D as detailed in the Cakerawala Field Development Plan
Update  1  approved  by  MTJA,  as  may be amended, modified or supplemented and
approved  by  MTJA  until  such  costs  are  fully  recovered  by  Contractors;

For the avoidance of doubt, it is agreed and understood that the said facilities
will not be installed simultaneously and such maximum allowable cost recovery of
sixty  per  cent  (60%)  shall  apply  from  time  to  time;

(iii)     All  detailed  accounts that are required to be provided under Article
11  shall  identify  the  allowable costs permitted under (i) and (ii) above, so
that  the accounts for which a maximum allowable cost recovery of sixty per cent
(60%)  is  allowed  can  be  easily  identified and distinguished from all other
allowable  costs to be recovered by the Contractors for a maximum allowable cost
recovery  of  fifty per cent (50%) and can be audited in accordance with Article
11;  and

(iv)     All allowable costs pertaining to expenditures identified under (i) and
(ii)  above  shall  be recovered first and shall be fully recovered prior to the
recovery  of all other allowable costs which may be recovered by the Contractors
at a maximum allowable cost recovery of fifty per cent (50%) during any Quarter.

Contractors  are  entitled to recover all such allowable costs from the proceeds
of  Natural  Gas  sold  equal  to  the amount of all such allowable costs in the
Contract  Area  (but  subject  to  Article  8.7).

If  in  any  Quarter all such costs expended relating to Petroleum Operations in
respect  of  Natural  Gas (including amounts accumulated or carried forward from
previous Quarters) exceed the maximum permitted value of fifty per cent (50%) or
sixty  per cent (60%) as provided above, as the case may be, of such Natural Gas
sold  from  the  Contract Area, the unrecovered excess may be carried forward to
the  next  succeeding  Quarter  and  added  to all such allowable costs expended
relating to Petroleum Operations in respect of Natural Gas for that Quarter, but
provided  that  such costs can only be recovered for any Quarter up to a maximum
of  fifty  per  cent (50%) or sixty per cent (60%) , as the case may be, of such
Natural  Gas  sold."

2.     Except  as expressly provided in this Supplementary Contract (No. 2), the
Principal  Contract is not otherwise waived, amended and supplemented hereby and
the  terms  therein  shall  remain  in  full  force  and  effect.

3.     Any terms that are defined terms in the Principal Contract shall have the
same  meaning  when  used  in  this Supplementary Contract (No. 2) unless herein
otherwise  expressly  provided.


IN  WITNESS  WHEREOF  MTJA,  CARIGALI,  TRITON  and  TRITON  JDA  have  by their
respective duly authorised officers executed this Supplementary Contract (No. 2)
on  the  day  and  year  first  herein  above  written.
