           3.3.1      CONTRACTOR  agrees and undertakes to maintain the drilling
                      fluids  (mud) in  accordance  with the  specifications  of
                      COMPANY's drilling program, as provided by the Mud company
                      representative furnished by COMPANY.


            3.3.2   CONTRACTOR shall use its best endeavors,  in accordance with
                    good oil field practices,  to maintain deviation of the well
                    within the  limits  specified  by  COMPANY  in the  drilling
                    program.  As  often  as  COMPANY  requires,  measurement  of
                    deviation shall be made by CONTRACTOR with its equipment and
                    by methods acceptable to COMPANY.  Should deviation from the

                    special  equipment  and/or  services to make such corrective
                    measures.  CONTRACTOR  shall  deliver  to  COMPANY  the data
                    pertaining to all  meseaurments  made by CONTRACTOR  and all
                    records resulting therefrom.

           3.3.3      Before running casing,  CONTRACTOR agrees to condition the
                      well, if necessary, so that the well will be free from all
                      obstructing  particles  which might impede  running of the
                      casing. CONTRACTOR agrees to keep thread protectors on the
                      casing stands until they are run and to grease the threads
                      with a suitable thread compound.

           3.3.4      If, during drilling  Operations,  CONTRACTOR  encounters a
                      formation  which  reasonably  appears  to be  oil  or  gas
                      bearing,   CONTRACTOR   shall  stop   drilling  and  allow
                      COMPANY's  Representative  to  examine  the  formation  to
                      decide  what  further   Operations,   if  any,  should  be
                      conducted.

                               coventurer Shelf  Philippines  Exploration  B.V.,
                               their  respective  parent(s),   subsidiaries  and
                               affiliates  and  their  officers,  directors  and
                               employees;   and  CONTRACTOR  shall  include  its
                               parent(s),  subsidiaries and affiliates and their

                    in defending  against asserted claims,  for certain areas of

                    CONTRACTOR  has assumed  liability or  responsibility  for a
                    claim,  loss or damage or has  undertaken  to indemnify  the
                    other  party,  the  provision of this  Contract  will apply,
                    notwithstanding  gross, sole and/or concurrent negligence or
                    fault of either  COMPANY  or  CONTRACTOR,  either  active or
                    passive,   unseaworthiness   of  vessels   (whether  or  not
                    preexisting), and/or any theory of strick liability relating
                    to ruin or  defective  premises,  equipment,  facilities  or
                    appurtenances  of either party under any applicable  code or
                    law, any other type of strict liability, whether or not such
                    preexists  this  Contract   and/or  is  latent,   patent  or
                    otherwise.

           7.2.2      Waiver of Subrogation

                         For the risk assumed by each party  hereunder,  neither
                    the underwriters, insurers, nor insurance carriers of either
                    party hereto will have any right of subrogation  against the
                    other party hereto, or its agents, labor, invitees, servants
                    or  coventurers;   or  against  underwriters,   insurers  or
                    insurance  carriers of the other  party;  and such rights of
                    subrogation  with respect to Operations  under this Contract
                    are mutually  waived.  All policies of insurance  possessed,
                    procured or  maintained by either party will be suitably and
                    adequately endorsed to effectuate the waiver of subrogation.

                      Annex E, COMPANY and its  coventurers,  if any,  shall for

                      additional   insured  on  all  coverages.   All  insurance
                      policies  shall,   for  the  risk  assumed  by  CONTRACTOR
                      hereunder,  state the underwriters'  waiver of subrogation
                      and  recourse  against  COMPANY,   its  coventurers,   its
                      underwriters and its contractor and subcontractors.

                      All insurance  provided by CONTRACTOR shall be primary and
                      not  contributory  to any  other  insurance  available  to
                      COMPANY,  to the extent CONTRACTOR has expressly agreed to
                      be liable under this Contract.

                      to  cover  its  own   liabilities   as  per  Article  7.1.
                      CONTRACTOR  shall be named as coinsured  in the  COMPANY's
                      insurance  policies,  which shall state, in addition,  the
                      underwriter's  waiver of subrogation and recourse  against
                      CONTRACTOR    and     CONTRACTOR's     underwriters    and
                      subcontractors.

           7.2.4      Payment of Insurance Premiums

                      The  cost  of  the   different   policies   contracted  by
                      CONTRACTOR  (including  those  that do not  apply  to this
                      Contract)  is  included in the Day Rates,  and  CONTRACTOR
                      shall be responsible for payment of the related premiums.

                      policies or the cover specified therein, provied the cover
                      to the benefit of CONTRACTOR thereby shall not
                      be reduced.  The increase in  premiums, resulting from

                      of corresponding vouchers.


PART 8 - MISCELLANEOUS

8.1        UNSATISFACTORY PERFORMANCE

           COMPANY  is  entitled  to take  over the  operation  of  CONTRACTOR's
           equipment in the following circumstances and subject to the following
           conditions:

           In the event that  COMPANY  becomes  dissatisfied  with  CONTRACTOR's
           conduct of the  Operations  hereunder on account of slow  progress or
           incompetence  in the  performance  of this  Contract,  as a result of
           causes  reasonably  within the control of  CONTRACTOR,  COMPANY shall
           notify   CONTRACTOR,   in  writing,   the  detailed  grounds  of  its
           dissatisfaction.  Should  CONTRACTOR  fail or refuse  to  remedy  the
           matters  complained of or not take steps and diligently proceed to so
           remedy such matters  within two (2) days after the written  notice is
           received by CONTRACTOR,  COMPANY shall have the right, at its option,
           to either take over the operation of  CONTRACTOR's  equipment for the
           purpose of completing  the drilling of the well or to terminate  this
           Contract.  Should  Operations  be taken over by COMPANY,  the cost of
           such  Operations  shall  be  paid  for  by  the  COMPANY,  who  shall
           compensate  CONTRACTOR for the use of  CONTRACTOR's  drilling  tools,
           machinery and  appliances at the applicable  Rate,  less all expenses
           and costs incurred by COMPANY in such  Operations.  COMPANY shall, on
           the completion of the work, return such drilling tools, machinery and
           appliances  to  CONTRACTOR  in as good  condition as when taken over,
           normal  wear  and  tear  excepted.  In  the  event  of  the  drilling
           Operations  being  taken over by  COMPANY,  as herein  provided,  all
           Operations  thereafter shall be conducted at the sole risk of COMPANY
           and  the  liability   provisions   of  this  Contract   intended  for
           CONTRACTOR's  account shall become liabilities for COMPANY's account.
           Subject to underwriter approval, CONTRACTOR shall transfer to COMPANY
           benefit of all policies ensuring CONTRACTOR's operations.

8.2        FORCE MAJEURE

           Each party to this contract  shall be excused from complying with the
           terms of this  Contract  (except for the payment of monies when due),
           and  neither  party to this  Contract  shall be liable for failure to
           perform  under the term of this  Contract  if and for so long as such
           performance is hindered or impeded by Force Majeure, which is defined
           as civil or labor  disturbances,  riots,  strikes (other than strikes
           limited  solely  to  CONTRACTOR's   Personnel),   wars  (declared  or
           undeclared), military actions, insurrection,  rebellion, terrorist or
           anti-government  acts,  acts of any  Governmental  or military agency
           under  actual or assumed  authority,  action of  elements  (excluding
           adverse sea and weather conditions),  floods, storms or other acts of
           nature, or any

                                                         
<PAGE>



           cause beyond the control of either  party,  whether or not similar to
           the matters herein specifically enumerated; and, provided that, where
           applicable,  none of the above  shall  have been  caused by action or
           negligence  of either of the parties.  However,  the party and/or the
           parties shall take any steps under its and/or their control to remedy
           the above circumstances.

           Inability  of either  party to secure  funds,  arrange  bank loans or
           other  financing  or obtain  credit  shall not be  regarded  as Force
           Majeure.

8.3        BANKRUPTCY OR ABANDONMENT OF OPERATIONS BY CONTRACTOR

           Should  CONTRACTOR  becomes  insolvent or enter into any  arrangement
           with or for the benefit of its creditors, or becomes unable or refuse
           or neglect to carry out the  Operations  or any part  thereof,  or if
           CONTRACTOR's equipment is seized or put in execution, COMPANY may, by
           notice,  in writing,  to CONTRACTOR,  terminate this Contract without
           thereby affecting in other respects the obligations or liabilities of
           CONTRACTOR.  On  such  termination,  all  use  by  CONTRACTOR  of the
           equipment,  implements  and  materials  shall cease,  and COMPANY may
           employee  other  contractors  or workmen to perform and  complete the
           work or may itself  complete  the same,  and the costs,  charges  and
           expenses of such  completion  in excess of that which  COMPANY  would
           have paid had the event not  occurred  may be deducted by the COMPANY
           from any monies due to or become due to the CONTRACTOR.

8.4        NON-WAIVER

           No requirement hereof and, in particular,  no breach of this Contract
           hereunder,  shall be  considered as waived by either party unless the
           same is  specifically  waived in writing and then only by the persons
           executing   this   Contract  or  other  duly   authorized   agent  or
           representative of the party.

                      applied,  and the same laws shall  exclusively  govern the
                      merits of any dispute as referred to in Article 8.5.2.

                         based on any other legal  doctrine  which may arise out
                         of  or  in   connection   with  this  Contract  or  the
                         interpretation,  application, implementation, validity,
                         breach  or  termination  of  this  Contract  or of  any
