     1.     The  specific  agreement  terms  stated  on  page  one  and  on  the
Attachrnent(s)  to  this  agreement  shall  control  over  the following general
provisions  and  altogether  comprise  an integrated contract between Texaco and
Seller.
     2.     The  term  "crude  oil"  as used in this agreement shall include all
marketable  liquid  hydrocarbons.
     3.     All  crude  oil  delivered  to  TTTI  under  this agreement shall be
merchantable  crude  oil.  Title  and risk of loss shall pass to TTTI as soon as
TTTI  receives such crude oil into its custody or that of any carrier designated
by  it.
     4.     TTTI  shall  compute  quantity  and quality and make corrections for
temperature  and  deductions for impurities according to the prevailing API/ASTM
standards  in  effect  at  the  time  and  place  of  delivery  and the laws and
regulations  prescribed  by  the  governmental  authorities having jurisdiction.
     5.     Seller  warrants  that  all crude oil delivered under this agreement
will  be  produced  and  delivered  in  compliance  with all applicable laws and
regulations; and free of any and all claims against title when received by TTTI.
     6.     If  TTTI  makes payment to the individual owners of interests in the
crude oil to be delivered to TTTI under this agreement, Seller agrees to provide
accurate  information  concerning  each  owner's title sufficient to enable TTTI
to  make  such  payments  to  protect, indemnify and hold harmless TTTI from any
claims  resulting  from  errors or omissions in such information. TTTI agrees to
protect,  indemnify  and  hold  harmless  Seller  from any claims resulting from
errors  or  omissions  made  by  TTTI in making  payments in accordance with the
information  provided  by  Seller.
     7.     If payment by TTTI to Seller includes payment for interests owned by
others  in  the crude oil, Seller agrees to pay all persons and entities who may
have  any right, title or interest in and to the crude oil and further agrees to
protect,  indemnify  and  hold  harmless TTTI from any claims for payment by any
such  persons  and  entities.
     8.     Neither  party  shall be liable to the other for failure or delay in
making or  accepting  delivery hereunder to the extent such failure or delay may
be due to  compliance with acts, orders, regulations or requests of any federal,
state or  local  civilian or military authority or any persons purporting to act
therefor;  riots;  strikes;  labor  difficulties;  action  of  the  elements;
transportation difficulties; any subsequently enacted law or regulation having a
material  adverse  economic  impact  upon either party's ability to perform this
agreement;  or  any  other  cause  reasonably  beyond the control of such Party,
whether  similar  or  not.
     9.     This  agreement  shall be governed by the laws of the state in which
the crude  oil  is  produced.
     10.    In addition to the legal rights provided by the terms and provisions
of this document, the Seller may have certain statutory rights under the laws of
the  state  of  production.
