the conduct of Exploitation operations on each Pool discovered
shall be operated jointly, beginning at the award of the
Exploitation Licence, by SONATRACH and ANADARKO who shall, for
that purpose, establish an Exploitation Operations Committee
according to the following provisions.

6.4  Between the dates Operator submits to the Operating
Committee a Discovery Report pursuant to Paragraph 12.1 and a
Development Work Program and Budget pursuant to Paragraph 12.9,
the Operating Committee shall commence discussions relative to a
plan of dual operatorship.  The Operating Committee shall
endeavor to reach agreement for a plan of dual operatorship not
later than the date of the award of the Exploitation Licence
applicable to the first Pool to be developed.  The agreement so
reached is herein called the "Dual Operatorship Plan".  Unless
the Parties agree otherwise, no Exploitation operations shall be
undertaken until the Dual Operatorship Plan has been approved by
the Parties.

6.5  The Dual Operatorship Plan shall:

          A.   Be stated in a written agreement between the
          Parties, being subject to all the terms and provisions
          of this Agreement concerning the rights and obligations
          of the Parties and the Operator;

          B.   Be limited in scope to Exploitation operations,
          unless the Parties agree otherwise;

          C.   Contain a procedure for a phase-in of personnel

          one-half (1/2) by SONATRACH;

          D.   Remain in effect so long as this Agreement remains
          in effect;

          E.   Conform to the provisions stated in Paragraph 6.6
          below;

          F.   Be applicable to all Pools discovered, unless
          SONATRACH requests ANADARKO to carry out solely the
          role of Operator of a particular Pool;

          G.   Provide an equitable manner in which Overhead
          stated in Annex "B" will be allocated between
          Exploration and Exploitation operations so as to
          minimize duplication of services and costs.

6.6  The following provisions shall regulate the Exploitation
Operations Committee:

          A.   To insure joint execution of Exploitation
          operations, and within the framework of the Dual
          Operatorship Plan, the Operating Committee shall reach
          agreement as to the organization and structure of the
          Exploitation Operations Committee;

          B.   During the time ANADARKO serves as the Operator,
          the Technical Advisory Committee shall remain in
          effect.  Thereafter, the Operating Committee shall
          determine whether to continue or discontinue that
          committee, or to absorb its functions into the
          functions of the Exploitation Operations Committee;

          C.   The Exploitation Operations Committee shall be
          managed by two (2) Operations Managers, one (1) of whom
          shall be designated by SONATRACH and the other by
          ANADARKO.  The two Operations Managers shall be jointly
          responsible for managing the current affairs of the
          Exploitation Operations Committee.  However, their
          respective responsibilities shall be as determined by
          the Operating Committee;

          D.   The Exploitation Operations Committee shall not be
          a juristic entity:

          E.   The Exploitation Operations Committee will act
          solely for the account of both Parties on the
          directives and under the control of the Operating
          Committee;

          F.   The Exploitation Operations Committee shall be
          subject to the same provisions stated in this Agreement
          which are applicable to the Operator.

6.7  ANADARKO may resign from its duties as Operator during the
Exploration Phase and as a member of the Exploitation operations
Committee during the Exploitation Phase if six (6) months' Notice
is delivered to SONATRACH before the date of resignation.
ANADARKO may only resign from its duties as the Operator during
the Exploration Phase on the condition that it has fulfilled its
obligations relative to the Minimum Exploration Program.

6.8  Notwithstanding that resignation, ANADARKO'S responsibility
as Operator shall remain until the effective date of its
resignation.

6.9  SONATRACH, or the legal entity appointed to serve as
Operator or as a member of the Exploitation Operations Committee
upon ANADARKO'S resignation from its duties as Operator, shall
not be bound by the studies, technical and/or financial
conclusions of ANADARKO prior to its resignation.

6.10 SONATRACH will have the right to temporarily withdraw
ANADARKO'S status as Operator during the Exploration Phase and
during the Exploitation Phase in the case of a default in its
obligations as stipulated in Paragraphs 7.1 and 7.2 herein.  To
this end SONATRACH will address to ANADARKO an advance Notice
asking it to remedy its default within the time which will be set
in the said advance Notice subject to the circumstances.
     However, except for default which may cause loss of the
Exploration Licence, the stipulations of the foregoing paragraph
do not apply during the Exploration Phase in the case of the
conduct of Petroleum Operations financed at the sole risk of
ANADARKO.

          Petroleum Operations. However, at all times, Operator
          will be  entitled to examine or analyze the said cores,
          cuttings and fluids, and to take samples in reasonable
          quantities and volume. Furthermore, with SONATRACH'S
          approval, Operator will be entitled to export samples
          of cores, cuttings and fluids that were collected.
          Should it become necessary to conduct special whole
          core analyses in a laboratory outside of Algeria and,
          if SONATRACH agrees, Operator may export the core(s)
          under its sole responsibility and control to the
          designated laboratory;

          K.   Keep in Algeria the originals of magnetic tapes
          and, at the end of their processing or analysis,
          transfer the said tapes to SONATRACH.  Copies of
          magnetic tapes or any other technical data which
          Operator desires to have processed or analyzed outside
          Algeria may be exported;

          L.   Perform such other tasks relating to Petroleum
          Operations as directed by the Operating Committee.

7.2  Operator endeavors to conduct Petroleum Operations in a
good, prudent and workman-like manner in accordance with sound
technical principles and good petroleum industry practice.  In
the conduct of Petroleum Operations, SONATRACH acknowledges that
Operator does not guarantee that its efforts will result in a
Commercial Discovery, and that Operator will be responsible only
for providing the means to conduct and of conducting Petroleum
Operations.

7.3  In conducting Petroleum Operations, Operator will not be
liable to Non-Operator for anything done or omitted to be done by
it unless the act or omission causes a loss which is directly due
to Operator's gross negligence or willful misconduct.

7.4  SONATRACH'S ASSISTANCE

     Within the scope of the conduct of Petroleum Operations,
SONATRACH shall, within legal and regulatory limits, give aid to
the Operator to:

     Facilitate its personnel's rights of ingress to and egress
     from the Contract Area and eventually, the surrounding
     areas.

     Accomplish the necessary formalities in obtaining, on the
     one hand, entry and exit visas for its resident expatriate
     personnel or personnel on business trips to Algeria and, on
     the other hand, required authorizations to import into or
     export from Algeria documents and/or materials used in the
     execution of the said operations.

     SONATRACH shall make available to the Operator, without
incurring any liability for exactness, documents, magnetic tapes,
and geological and geophysical information relating to the
Contract Area and that necessary for use in conducting Basin
Evaluation efforts.  If ANADARKO asks SONATRACH to reproduce and
furnish to ANADARKO copies of any such data or information,
ANADARKO agrees to reimburse SONATRACH for its actual cost
incurred.  ANADARKO agrees to use the documents, magnetic tapes,
and geological and geophysical information mentioned above only
for Petroleum Operations under this Agreement.
                            TITLE III
                        EXPLORATION PHASE
                                
                            ARTICLE 8
                          CONTRACT AREA


8.1  The exclusive coordinates of the Contract Area which
comprise the four (4) Exploration Blocks are defined in Annex
"A".

8.2  SONATRACH undertakes that it will not waive, within the
framework of this Agreement, its rights to the Exploration
Licence, to any Provisional Exploitation Authorization or to any
Exploitation Licence awarded without ANADARKO's prior written
consent.  The Parties agree that neither will fail to comply with
any obligation which will cause SONATRACH'S mining title to be
cancelled by the Competent Authority.

8.3  If during the Exploration Phase ANADARKO reasonably believes
that a portion of the Contract Area is not of sufficient economic
potential to justify that ANADARKO start an additional
Exploration Work Program on that portion, ANADARKO shall submit
to SONATRACH a detailed report containing technical and economic
data which supports its position.  The report shall also
indicate, based upon Basin Evaluation efforts conducted by
ANADARKO, that parcel of land outside the Contract Area which,
provided this parcel is a free area under Article 12 of Law
86-14, may be appropriately substituted for the portion of the
Contract Area stated in ANADARKO'S report to enable ANADARKO to
complete its Minimum Exploration Program obligations.  That
report shall include a substitute Exploration Work Program
(herein referred to as the "Substitute Exploration Work Program)
which ANADARKO proposes to undertake on the new parcel of land
(herein referred to as the "Substitute Area").  Within forty-five
(45) days following receipt by SONATRACH of that report, the
Operating Committee shall meet to consider, discuss and approve
such report and the Substitute Exploration Work Program proposed
by ANADARKO.
     If SONATRACH agrees with ANADARKO'S report and the proposed
Substitute Exploration Work Program, then it will submit to the
Competent Authority a request for a new Exploration Licence
covering the Substitute Area and a request for a partial
relinquishment for the areas substituted conforming to the
regulatory provisions applicable for this matter.  If the
Competent Authority accepts the request submitted by SONATRACH,
then the new Contract Area shall be made up of the portion of the
initial Contract Area remaining and the Substitute Area.  If the
Competent Authority refuses the request submitted by SONATRACH
regarding the substitution of areas, ANADARKO shall be held to
pursue the Minimum Exploration Program as it committed to
pursuant to Article 10 herein.  No Work Program approved by the
Operating Committee shall be suspended from execution based on
the submittal of a request as mentioned above, as long as the
Competent Authority has not ruled on the request.
     If the request for substitution of an area mentioned above
is accepted by the Competent Authority, then ANADARKO shall have
no right to make other requests during the Exploration Phase.  If
the request for substitution is refused by the Competent
Authority, then ANADARKO may make another request during the
Exploration Phase.
     If SONATRACH does not agree with ANADARKO'S report or the
Substitute Exploration Work Program proposed, then ANADARKO'S
remaining obligations under the Minimum Exploration Program shall
be reduced by the amount of Exploration work which would have
been conducted for the Minimum Exploration Program on the portion
of the Contract Area which is the subject of the proposed
substitution.  In that event, and without prejudice to the
provisions of Paragraphs 8.7 and 8.8, the portion of the Contract
Area stated above will be deleted from the Contract Area at the
time of disagreement.

8.4  Exploration Costs incurred with respect to areas
relinquished in compliance with this Article 8 shall be carried
forward and consolidated with Exploration Costs incurred on the
totality of the Contract Area.  All costs incurred by ANADARKO
with respect to Basin Evaluation work which is exclusively
related to an area or areas added pursuant to Paragraphs 8.3 and
8.6 shall be included as Exploration Costs reimbursable to
ANADARKO according to the applicable provisions of this
Agreement.

8.5  Should Exploration works show a geological structure
overlapping an area adjacent to the Contract Area, SONATRACH will
request the Competent Authority to add this area to the Contract
Area if it is a Free Adjacent Area.  If that parcel of land is
not a free area, the Parties shall endeavor to reach agreement
with the Third Party(ies) involved for the joint Exploitation of
the discovered Pool overlapping the Contract Area and the said
area, and for an equitable distribution of the Liquid
Hydrocarbons produced from that Pool.

8.6  If the Parties agree that the expansion of the Contract Area
would be advantageous for the conducting together of their
Exploration activities, SONATRACH agrees to request the competent
Authority to include those free areas in the Contract Area as
provided in Article 12 of Law 86-14.

8.7  Upon expiration of the First Exploration Period stated in
Paragraph 9.1 A the surface area of the Contract Area shall be
reduced by an amount equal to the greater of, whichever is
applicable:

          A.   Twenty five percent (25%) of the Contract Area; or

          B.   Twenty five percent (25%) of the Contract Area,
          plus (if applicable) an additional five percent (5%)
          for each of the six (6) Exploration Wells specified in
          Paragraph 10.1 D in which Drilling has not commenced as
          of that expiration date.

8.8  Upon expiration of the Second Exploration Period stated in
Paragraph 9.1 B:

          A.   If ANADARKO exercises the option stated in
          Paragraph 8.9, the surface area of the Contract Area
          shall be reduced by an amount which results in the
          Contract Area containing a remaining surface area equal
          to fifty percent (50%) of the size of the Contract Area
          prior to reduction under Paragraph 8.7 above; or

          B.   If ANADARKO does not exercise the option stated in
          Paragraph 8.9, the surface area of the Contract Area
          shall be reduced:

                    1.   To a size which contains only the full
               extent of the area of the Pools in which Liquid
               Hydrocarbons have been discovered, as provided in
               Paragraph 8.10; or

                    2.   Subject to Article 9, by one hundred
               percent (100%) if ANADARKO elects to withdraw from
               this Agreement.

8.9  Subject to the provisions of Paragraph 9.4 relative to the
extension of time, ANADARKO shall have the option to continue
Exploration works on the Contract Area after expiration of the
Second Exploration Period stated in Paragraph 9.1 by submitting
to SONATRACH, at least seven (7) months prior to expiration of
that period, a supplementary Exploration Work Program which is in
addition to the Minimum Exploration Program therein referred to
as the "Supplemental Exploration Work Program").  If SONATRACH
agrees to the Supplemental Exploration Work Program, the
reduction in the Contract Area shall be as specified in Paragraph
8.8 A above.

8.10 No reduction in the surface area of the Contract Area shall
be required in respect of the full extent of each Pool covered by
an Exploitation Licence.  Reductions in the surface area of the
Contract Area scheduled to be made under either Paragraph 8.7 or
8.8 shall be deferred if either of the following events has
occurred and for a period of sixty (60) Days following expiration
of the applicable event:

          A.   Petroleum Operations are suspended by reason of
          Force Majeure; or

          B.   An application for a Provisional Exploitation
          Authorization or an Exploitation License has been
          submitted to the Competent Authority, but the award is
          pending; or

          C.   SONATRACH has been notified of the discovery of
          Hydrocarbons, but the Operating Committee has not taken
          a decision as to whether the discovery is commercially
          exploitable.

8.11 ANADARKO shall notify SONATRACH seven (7) months in advance
of the date of its proposed reduction under Paragraphs 8.7 and
8.8 A of the portion of the Contract Area proposed to be reduced.
The advance Notice required for the reduction under Paragraph 8.8
B shall be thirty (30) days.  So far as possible, the portions
reduced shall be of sufficient size and shape to enable Petroleum
Operations to be conducted thereon.

8.12 If with respect to any part of the Contract Area which has
been reduced under this Article 8, or if upon expiration of the
term of this Agreement, ANADARKO desires to make a request for
continued Petroleum Operations regarding one or more parts of the
original Contract Area, then, provided such parts of the Contract
Area are free areas under Article 12 of Law 86-14, SONATRACH
agrees to give sympathetic consideration to such request, in
priority to ANADARKO over Third Parties.
                            ARTICLE 9
                  TERM OF THE EXPLORATION PHASE


9.1  The term of the Exploration Phase shall include a First
Exploration Period and a Second Exploration Period and respective
extensions thereof:

          A.   The first period of the Exploration Phase shall
          last for five (5) Contract Years (herein referred to as
          the "First Exploration Period") beginning on the
          Commencement Date.

               The First Exploration Period shall be extended for
          a period of one (1) Contract Year if necessary to
          complete the Drilling of one or more of the six (6)
          Exploration Wells stated in Paragraph 10.1.D.1.
          ANADARKO shall notify its request for extension to
          SONATRACH at least seven (7) months prior to the
          expiration of the First Exploration Period and shall
          attach thereto all necessary documents.

          B.   The second period of the Exploration Phase shall
          last for three (3) Contract Years (herein referred to
          as the "Second Exploration Period").

               The Second Exploration Period will be extended
          for:

                    1.   One (1) Contract Year, if needed, to
               enable ANADARKO to complete the Drilling of one or
               more Delineation Wells; or

                    2.   Two (2) additional Contract Years, if
               ANADARKO exercises the option stated in Paragraph
               8.9, and SONATRACH agrees to the Supplemental
               Exploration Work Program submitted by ANADARKO.

     With at least seven (7) months' Notice prior to expiration
of the then current Exploration Period and in the manner required
by Law, ANADARKO shall furnish to SONATRACH who will submit the
same to the Competent Authority all documents necessary for each
request of renewal of an Exploration Licence.

9.2  If at the expiration of the Exploration Phase (as extended
in accordance with Paragraph 9.1.B.2) no Commercial Discovery has
been established, then this Agreement shall terminate unless:

          A.   Petroleum Operations are then suspended by reason
          of Force Majeure.  In that event, this Agreement shall
          continue for a period of time during which Petroleum
          Operations were so suspended in accordance with Article
          25; or

          B.   ANADARKO is engaged in Drilling operations.  In
          that event, this Agreement shall continue for a period
          of six (6) months following completion of those
          Drilling operations.

     If, however, the Drilling operations (or Drilling operations
conducted during the period extended by reason of Force Majeure)
result in a discovery, this Agreement shall continue until a
determination is made whether or not that discovery is a
Commercial Discovery and whether an application should be
submitted for an Exploitation Licence.  If a determination is
made that a Commercial Discovery has been made, then this
Agreement shall continue for the term of the Exploitation Phase.

9.3  With respect to those portions of the Contract Area released
under Article 8, ANADARKO shall not be entitled to any right or
interest arising from its prior Petroleum Operations on those
portions except as provided in Paragraphs 8.4 and 8.12 of this
Agreement.

9.4  The postponement of deadlines or extensions of the duration
of the Exploration Periods mentioned in Paragraphs 9.1 and 9.2
herein shall be effective only if approved by the Competent
Authority according to the provisions of Decree No. 88-34 of
February 16, 1988, relating to the granting and renewal of
Exploration Licences.  SONATRACH will give Notice to ANADARKO of
all refusals or injunctions by the Competent Authority resulting
from a request to postpone the deadlines or to extend the
duration of an Exploration Period as mentioned above.  If the
Competent Authority issues an injunction relating to the
execution of the Minimum Exploration Program, then ANADARKO may
either commit to take the necessary measures to comply with the
said injunctions within the time eventually prescribed by the
Competent Authority, or in the case where ANADARKO considers that
these injunctions are not justified or if it decides not to
comply with the injunctions it may withdraw from the Exploration
Licence under the condition, however, to pay SONATRACH, within
thirty (30) Days following, an amount equal to the difference
between the value of the Exploration works which had to be
performed during the period at the end of which it withdraws and
the Exploration Costs incurred at the date of its withdrawal.  In
any case, the value of the Exploration works mentioned above for
the First Exploration Period cannot be less than U.S. $63.5
Million where U.S. $48 Million will be for Drilling.
     ANADARKO will not have rights to any indemnification or
reimbursement of the sums stipulated above as penalty based on
the refusal of postponement of deadlines or extensions mentioned
above formulated by the Competent Authority taken at the end of
each period of the Exploration Phase.  However, for Exploration
Costs incurred before the date where ANADARKO refused to conform
to the injunctions of the Competent Authority, the provisions of
Article 18 will be applied in the case of the Exploitation of a
Commercial Discovery.
     Any withdrawal by ANADARKO pursuant to this Paragraph shall
be without prejudice to its rights of Exploitation derived from
any previous Commercial Discovery pursuant to Article 12.
                           ARTICLE 10
                   MINIMUM EXPLORATION PROGRAM


10.1 During the Exploration Phase, ANADARKO shall conduct, and
furnish all sums necessary to finance, a Minimum Exploration

               data furnished by SONATRACH under Paragraph 7.4 of
               this Agreement which ANADARKO determines is
               necessary for the evaluation of the prospective
               potential of the Contract Area;

                    2.   The conduct of geophysical exploration
               through the acquisition of at least one thousand
               (1,000) kilometers of new seismic data over the
               Contract Area, together with the processing and
               interpretation of that data;

          B.   Basin Evaluation efforts stated in Annex "C";

          C.   The installation, operation and maintenance of the
          Seismic Processing Center pursuant to Annex "D";

          D.   The Drilling of ten (10) Exploration Wells on the

                    1.   Six (6) Exploration Wells will be
               drilled during the First Exploration Period; and

                    2.   Four (4) Exploration Wells will be
               drilled during the Second Exploration Period.

               If, during the First Exploration Period, ANADARKO
          drills more than six (6) Exploration Wells, the excess
          Exploration Wells drilled shall be credited against
          Exploration Wells required to be drilled during the
          Second Exploration Period.

          E.   If a discovery of Liquid Hydrocarbons is made, the
          Drilling of up to two (2) Delineation Wells to confirm
          whether that discovery is a Commercial Discovery,
          unless the Operating Committee determines either that:

                    1.   The discovery is a Commercial Discovery
               and it is not necessary to drill one or more
               Delineation Wells; or

                    2.   The discovery can be adequately drained
               by less than three (3) Wells; or

                    3.   The provisions of Paragraph 12.4 are
               applicable.
10.2 ANADARKO'S obligation to conduct the Minimum Exploration
Program shall be considered completely performed and satisfied
upon the first to occur of the following dates:

          A.   The date ANADARKO completes the Minimum
          Exploration Program; or

          B.   If ANADARKO does not complete the Minimum
          Exploration Program, the date ANADARKO has incurred
          Exploration Costs equal in value to U.S. One Hundred
          Million Dollars ($100,000,000.00), of which at least
          the equivalent of U.S. Eighty Million Dollars
          ($80,000,000.00) in Exploration Costs has been incurred
          for the Drilling of all or less than all the
          Exploration Wells specified in Paragraph 10.1 D above;
          or

          C.   To the dates and in the conditions mentioned in
          Paragraph 9.4 above.

10.3 Upon the first to occur of the dates stated in Paragraph
10.2 above:

          A.   ANADARKO will be conclusively deemed to have
          performed and satisfied all financial and work
          commitments required of it in respect of the Minimum
          Exploration Program;

          B.   Without prejudice to the foregoing subparagraph
          and the provisions of Article 9, ANADARKO shall have
          the right to continue Exploration efforts in an effort
          to make a Commercial Discovery during the remainder of
          the term of the Exploration Phase;

          C.   If no Commercial Discovery has been made, ANADARKO
          shall have the option to withdraw from this Agreement.

10.4 If, upon expiration of the Second Exploration Period (as
possibly extended by Paragraph 9.1 B.1) ANADARKO has neither
completed the Minimum Exploration Program nor incurred
Exploration Costs equal to U.S. One Hundred Million Dollars
($100,000,000.00) for those portions of the Minimum Exploration
Program stated in subparagraphs 10.1 A, B, C, and D above, then
ANADARKO shall pay to SONATRACH a sum equal to the difference
between U.S. One Hundred Million Dollars ($100,000,000.00) and
the total sum of Exploration Costs incurred for those portions of
the Minimum Exploration Program specified above.  Payment to
SONATRACH under this Paragraph shall be made not later than
thirty (30) days from the date of determination of the sum owed
by ANADARKO and in the manner directed by SONATRACH.
                           ARTICLE 11
              EXPLORATION WORK PROGRAMS AND BUDGETS


11.1 Not later than thirty (30) Days following the Effective Date
of this Agreement, Operator shall prepare and submit to the
Operating Committee for its review the proposed initial
Exploration Work Program which it proposes to conduct during the
first Contract Year.  The Operating Committee shall meet within
thirty (30) Days thereafter to review and decide on this program.

11.2 On or before October 1 of each Calendar Year other than the
initial Contract Year, Operator shall submit to the Operating
Committee its proposed Exploration Work Program for the next
succeeding Calendar Year.

11.3 Each proposed Exploration Work Program shall be submitted to
and approved by the Operating Committee and:

          A.   Contain all information as is necessary to
          describe fully Petroleum Operations to be conducted
          during the period covered thereby;

          B.   Be satisfactory as to enable ANADARKO to conduct
          Exploration in an orderly progression so that its
          Minimum Exploration Program obligations can be timely
          performed during the Exploration Phase.

     All Exploration work to be conducted will be as consistent
as possible with the Exploration Work Program approved for the
applicable Contract Year.  However, if, for a given period of the
Exploration Phase, Exploration work conducted during a Contract
Year exceeds that to be performed under an approved Exploration
Work Program, the excess shall be carried forward as a credit to
be applied against ANADARKO'S Exploration efforts to be conducted
by ANADARKO in the succeeding Contract Year.  Should ANADARKO
fail to conduct Exploration scheduled to be conducted during a
Contract Year, that part of Exploration not conducted shall be
made up in the succeeding Contract Year.

11.4 In accordance with Annex "B", Operator shall keep complete
books and records of all Exploration Costs incurred.
                            TITLE IV
                       EXPLOITATION PHASE
                                
                           ARTICLE 12
         EVALUATION, DETERMINATION AND DEVELOPMENT PLAN
                    OF A COMMERCIAL DISCOVERY


2.1  If a Hydrocarbon Pool is discovered, Operator shall promptly
notify Non Operator and, within ninety (90) Days, submit a report
to the Operating Committee specifying all pertinent information
concerning the discovery (herein called "Discovery Report"),
together with Operator's recommendation as to whether the
discovery warrants evaluation by the Drilling of one or more
Delineation Wells.

12.2 If Operator concludes that one or more Delineation Wells
should be drilled, Operator shall include with its Discovery
Report a proposed Work Program and Budget for such evaluation
efforts (herein called the "Evaluation Work Program and Budget").

12.3 Within fifteen (15) Days after receipt of the Discovery
Report, the Operating Committee shall meet to consider Operator's
recommendations.  Upon approval of an Evaluation Work Program and
Budget by the Operating Committee, Operator shall proceed with
the Drilling of those Delineation Wells contained therein, with
the understanding that all Delineation Wells (if any) in excess
of two (2) shall be considered Joint Operations.

12.4 If the Operating Committee concludes that the discovery does
not warrant or require the Drilling of any Delineation Well, or
if the discovery is a Non-Associated Gas discovery, then:

          A.   Operator shall not be obligated to drill any
          Delineation Well concerning that discovery;

          B.   If SONATRACH disagrees with Operator's conclusion,
          SONATRACH may drill such number of Delineation Wells as
          it believes are necessary to evaluate that discovery
          pursuant to the provisions of Article 13 hereof;

          C.   If the discovery is a Non-Associated Gas
          discovery, all further Petroleum Operations associated
          with that discovery shall be in accordance with Article
          19 of this Agreement.

12.5 If the Operating Committee fails to approve the Evaluation
Work Program and Budget proposed by Operator (or any amendment
thereto proposed by Non Operator), that part of the Evaluation
Work Program and Budget for which approval was not received shall
be deferred for reconsideration at a second meeting of the
Operating Committee to be held within fifteen (15) Days following
the date of the first meeting.  If, at the second meeting, the
Operating Committee fails to reach a decision, the Evaluation
Work Program and Budget proposed by Operator shall be deemed
approved by the Operating Committee if the works are to be
financed at ANADARKO'S sole risk.

12.6 If the approved Evaluation Work Program and Budget requires
a Provisional Exploitation Authorization to be obtained,
SONATRACH shall, within thirty (30) Days following the date of
approval of the Evaluation Work Program and Budget, submit an
application for a Provisional Exploitation Authorization for the
period determined by the Operating Committee and not exceeding
the maximum term authorized by Law.

12.7 Within thirty (30) Days following completion of the
Evaluation Work Program and Budget, Operator shall submit to the
Operating Committee a preliminary report (herein called the
"Evaluation Report") which sets forth all relevant available
technical and economic data, which shall include the geological
and geophysical information, thicknesses and depth of producing
zones, pressures, petro-physical properties of the Reservoir
rocks, results of analyses of fluids under pressure (PVT),
Hydrocarbon reserve estimates, anticipated drive mechanisms,
anticipated production performance for each Reservoir, relevant
characteristics and analyses of the Hydrocarbons discovered, and
other characteristics of the Reservoir and fluids contained
therein.

12.8 Within one hundred twenty (120) Days following the date
Operator submits the Evaluation Report, Operator shall submit to
the Operating Committee a second report (herein called the
"Commerciality Report") which states whether or not the discovery
is commercially exploitable.

12.9 If Operator concludes that the discovery is commercially
exploitable, Operator shall submit with the Commerciality Report
a proposed Development Plan and a proposed Work Program and
Budget (herein called the "Development Work Program and Budget")
which covers Exploitation operations to be conducted during the
balance of the year in which the Exploitation Licence is awarded
and the entire succeeding Calendar Year.

12.10     The proposed Development Plan shall be designed
following sound engineering and economic principles of the
petroleum industry, and:

          A.   It shall be designed to ensure that the Reservoir
          does not suffer an excessive rate of decline of
          production or an excessive loss of Reservoir energy;
          and

          B.   It shall adopt the optimum economic Well spacing
          for the project considered as a whole.

12.11     The Commerciality Report shall contain:

          A.   A copy of the Evaluation Report and a statement of
          Petroleum Operations conducted pursuant to the
          Evaluation Work Program;

          B.   An economic evaluation demonstrating whether the
          discovery may or may not be exploited profitably;

          C.   Provisions relating to:

                    1.   The Drilling of Development Wells;

                    2.   The design, engineering, construction
               and installation of equipment, lines, systems,
               facilities, materials and related equipment
               necessary to permit the production, collection,
               storage, processing for removal of Natural Gas
               Liquids, Transportation, delivery of Liquid
               Hydrocarbons, and the reinjection of Natural Gas;

          D.   A forecast of Liquid Hydrocarbons that may be sold
          during the Exploitation Phase from that discovery;

          E.   A forecast of the price that may be received from
          the sale of Liquid Hydrocarbons on the international
          market;

          F.   A statement of Exploration Costs incurred by
          ANADARKO in respect of that discovery, together with:

                    1.   A statement of all other unreimbursed
               Exploration Costs; and

                    2.   A forecast of Exploration Costs (if any)
               to be incurred in respect of all further
               Exploration efforts on the Contract Area.

          G.   A statement of Cost Recovery Liquid Hydrocarbons

          Exploitation Licence; and

          K.   Recommendations concerning the obtaining of an
          Exploitation Licence.

12.12     Within thirty (30) Days following receipt of the
Commerciality Report, the Operating Committee shall meet to
consider it.  If a proposed Development Plan and a proposed
Development Work Program and Budget were prepared and submitted
with the Commerciality Report, the Operating Committee shall also
review, discuss and attempt to reach unanimous agreement as to
those matters.

12.13     It is the responsibility of the Operating Committee at
the meeting held pursuant to Paragraph 12.12 above to determine
whether or not a discovery of Liquid Hydrocarbons is commercially
exploitable and, if prepared and submitted by the Operator, to
approve a Development Plan and a Development Work Program and
Budget for that Pool.  In that regard, the following provisions
shall be applicable:

          A.   If the Operating Committee unanimously agrees that
          the discovery is a Commercial Discovery, and if the
          proposed Development Plan and the proposed Development
          Work Program and Budget are approved unanimously, they
          shall be carried out after the granting of the
          Exploitation Licence as stipulated in Paragraph 12.14
          herein.  If the Operating Committee fails to
          unanimously approve the proposed Development Plan
          and/or the proposed Development Work Program and
          Budget, then those parts thereof which were not
          approved shall be deferred for reconsideration at a
          second meeting of the Operating Committee.  This
          meeting shall be held within thirty (30) Days following
          the date of the meeting held pursuant to Paragraph
          12.12 above.  If, at the second meeting, the Operating
          Committee fails to reach unanimous agreement as to
          those parts of the proposed Development Plan and/or the
          proposed Development Work Program and Budget, the
          disagreement shall be resolved in accordance with the
          procedure specified in Article 26 herein;

          B.   If the Operating Committee unanimously agrees that
          the discovery is not a Commercial Discovery, then all
          further operations in respect of that discovery shall
          be suspended;

          C.   If SONATRACH notifies ANADARKO that it believes
          the discovery is a Commercial Discovery, but ANADARKO
          is not in agreement, SONATRACH, pursuant to the
          provisions of subparagraph 13.1 B, shall conduct all
          further Petroleum Operations which it believes are
          necessary; and

          D.   If ANADARKO believes the discovery is a Commercial
          Discovery, but SONATRACH is not in agreement, the
          disagreement shall be resolved in accordance with the
          procedure specified in Article 26 herein.

12.14     Within thirty (30) Days following the date of approval
of the Development Plan and the Development Work Program and
Budget applicable to each Commercial Discovery, SONATRACH shall
submit to the Competent Authority an application for an
Exploitation Licence.  In other portions of the Contract Area,
Exploration may (or will, if ANADARKO has not satisfied its
obligations in respect of the Minimum Exploration Program)
continue concurrently with Development and Exploitation
operations.
                           ARTICLE 13
                SOLE RISK OPERATIONS OF SONATRACH


13.1 The provisions of this Article are applicable if:

          A.   SONATRACH elects to drill one or more Delineation
          Wells pursuant to subparagraph 12.4 B; or

          B.   SONATRACH elects to conduct further Petroleum
          Operations pursuant to subparagraph 12.13 C; or

          C.   During the Drilling of an Exploration Well,
          ANADARKO experiences mechanical difficulties or other
          geological circumstances and notifies SONATRACH that
          ANADARKO does not wish either to continue the Drilling
          of that Well at that location or to drill another
          Exploration Well in substitution of that Well, and
          SONATRACH elects to take over those Drilling
          operations; or

          D.   During the Drilling of an Exploration Well, and if
          ANADARKO refuses to perform supplementary works
          requested by SONATRACH, SONATRACH shall be able to
          conduct at its sole risk and expense all Drilling and
          coring operations or any other investigation for the
          purpose of recognizing or evaluating a formation during
          the Drilling of a Well.  SONATRACH may have these
          additional works conducted by the Operator, if it
          agrees, at the time and in the manner deemed best by
          the Operator taking into account the primary objectives
          of the Drilling in question.

13.2 Should SONATRACH desire to conduct Drilling operations
pursuant to subparagraph 13.1 A above, it shall have the right to
do so at its sole risk and expense, provided that it commences
those Drilling operations within six (6) months from the date it
notifies ANADARKO of its election under subparagraph 12.4 B.

13.3 Before SONATRACH commences Drilling or other operations
under this Article, the Parties shall reach agreement as to the
boundary of the area in which Drilling or other operations at the
sole risk and expense of SONATRACH shall be conducted.  If the
Drilling or other operations stated in subparagraphs 13.1 B and C
are conducted by SONATRACH, the area so determined shall be
reserved for SONATRACH'S exclusive use.

13.4 Upon completion of Drilling pursuant to subparagraph 13.1 A,
SONATRACH shall submit to the Operating Committee an Evaluation
Report and a Commerciality Report containing the information and
data stated in Article 12.

13.5 If the Commerciality Report with respect to Wells drilled
pursuant to subparagraph 13.1 A above confirms that the Liquid
Hydrocarbons are commercially exploitable, the Drilling of all
Development Wells and all further Petroleum Operations shall be
Joint Operations conducted at the expense of the Joint Account.

13.6 Liquid Hydrocarbons from each Pool developed pursuant to
Paragraph 13.5 above shall be divided as follows:

          A.   Liquid Hydrocarbons from Wells drilled at the sole
          cost, risk and expense of SONATRACH shall be produced
          solely for the account of SONATRACH until it has
          received an amount equal in value to five hundred
          percent (500%) of all costs and operating expenses
          borne solely by SONATRACH for the Drilling and
          equipping for production of the applicable Well(s);

          B.   Liquid Hydrocarbons from all Wells other than
          those stated in subparagraph A above (and Liquid
          Hydrocarbons from those Wells after recoupment by
          SONATRACH of the penalty mentioned above) shall be
          divided in accordance with Paragraph 4.3 above.

13.7 If SONATRACH elects to conduct further Petroleum Operations
not included in ANADARKO'S Work Program at its sole risk and
expense pursuant to subparagraph 13.1B, C or D above, and if a
Hydrocarbon Pool is consequently discovered, SONATRACH shall be
solely entitled to that discovery.  SONATRACH shall send Notice
to ANADARKO of the discovery.  ANADARKO shall have the option to
have its rights under this Agreement reinstated in that discovery
by paying cash, in the currency of SONATRACH'S choice, five (5)
times the total costs and expenses of works incurred by SONATRACH
at its sole cost, risk and expense.  The reinstatement option of
ANADARKO shall remain in effect for six (6) months from the date
ANADARKO receives the foregoing Notice from SONATRACH.  The sum
mentioned above shall be paid by ANADARKO within one (1) month
from the date it notifies SONATRACH of the exercise of its
reinstatement option.  The sum paid by ANADARKO to SONATRACH in
consideration of its reinstatement shall not be subject to any
reimbursement obligation by SONATRACH.

13.8 Except as provided in Paragraph 13.7 above, ANADARKO will
have no rights to Liquid Hydrocarbons coming from Pools
established by SONATRACH under subparagraphs 13.1 B, C or D, nor
will ANADARKO be obligated to share in the Exploitation Costs of
those Pools.
                           ARTICLE 14
                 TERM OF THE EXPLOITATION PHASE


14.1 The initial term of the first period of the Exploitation
Phase of each Pool shall be fifteen (15) years from the date the
Exploitation Licence is awarded (herein referred to as the "First
Exploitation Period").  If, due to delays in the installation of
evacuation pipelines by Operator or SONATRACH (or its Affiliate),
ANADARKO does not receive its share of Liquid Hydrocarbons from
that Pool during the term of the Provisional Exploitation
Authorization, the term of the First Exploitation Period of that
Pool shall be extended for that period of time necessary for
ANADARKO to receive a volume of Liquid Hydrocarbons equal to the
volume it would have received if the production from the Pool
could have been delivered by SONATRACH.

14.2 The First Exploitation Period of each Pool shall be extended
in the following manner:

          A.   ANADARKO shall have the option to extend the First
          Exploitation Period of each Pool for an additional
          period of five (5) years (herein referred to as the
          "Second Exploitation Period") by notifying SONATRACH of
          its option to extend the First Exploitation Period at
          least sixty (60) Days prior to expiration of the First
          Exploitation Period;

          B.   Before expiration of the Second Exploitation
          Period, and in order to determine if the term of the
          Exploitation Phase of the Pool in question should be
          extended for an additional period of five (5) years
          (herein referred to as the "Third Exploitation
          Period"), the Operating Committee shall determine if
          the Economic Limit of that Pool has or has not been
          reached.  If the Operating Committee unanimously agrees
          that the Pool in question has not reached its Economic
          Limit, then the Exploitation Phase of that Pool shall
          be automatically extended for the Third Exploitation
          Period.

14.3 If the Operating Committee fails to reach unanimous
agreement as to the Third Exploitation Period stated in
subparagraph 14.2 B above, the impasse shall be resolved as
follows:

          A.   If ANADARKO is of the opinion that Economic Limit
          has been reached as to a particular Pool, but SONATRACH
          disagrees with ANADARKO's opinion, ANADARKO shall have
          the option to withdraw from further participation in
          that Pool by notifying SONATRACH to that effect; or

          B.   If SONATRACH is of the opinion that Economic Limit
          has been reached as to that Pool, but ANADARKO
          disagrees with SONATRACH's opinion, the impasse shall
          be resolved in accordance with the procedure specified
          in Article 26 below.

14.4 If ANADARKO and SONATRACH agree that Economic Limit has been
reached, all Petroleum Operations associated with that Pool shall
be discontinued and equipment from that Pool shall be salvaged as
directed by the Operating Committee.

14.5 Upon the date the Parties agree that Economic Limit has been
reached in respect of the last Pool under Exploitation under this
Agreement, or the date ANADARKO elects to withdraw from further
participation in all Petroleum Operations pursuant to Article 30
hereof, this Agreement shall terminate.
                           ARTICLE 15
             EXPLOITATION WORK PROGRAMS AND BUDGETS


15.1 Operator shall prepare and submit to the Operating Committee
for consideration and approval the following documents relating
to the Joint Operations chargeable to the Joint Account:

          A.   Development Work Programs and Budgets, for which
          the Operating Committee shall meet initially at the
          time(s) stated in Paragraph 12.12 above, and thereafter
          meet at the time stated in Paragraph 5.9;

          B.   Exploitation Work Programs and Budgets, for which
          the Operating Committee shall meet at the times stated

Year, a proposed Work Program and corresponding Budget for the
next succeeding Calendar Year.

15.3 Each Work Program and Budget shall contain such information
as is necessary to describe fully the Petroleum Operations to be
conducted during the period covered thereby and the currency or
currencies in which costs and expenses are anticipated.

15.4 Within the time stated in Annex "B", each Party shall pay to
the Operator, in Dinars or in convertible Foreign Exchange, its
share of Cash Calls required to cover expenses of conducting
Development and Exploitation Work Programs.  Operator will not be
required to continue or to conduct such works, or to commit to
costs required therefor, if a Party has not paid its share of the
Cash Call due.

15.5 Except as otherwise provided:

          A.   With respect to specific projects within Budgets
          approved by the Operating Committee, Operator shall not
          be required to obtain any further approval of
          over-expenditures which do not exceed fifteen percent
          (15%) of the expenditure authorized for that project in
          the Budget for a given Calendar Year.  However, Notice
          of the need for additional expenditures shall be given
          to the Operating Committee as soon as the need becomes
          apparent.

          B.   Operator shall have no authority to use funds
          budgeted for a particular item for any other purpose;
          and

          C.   Operator shall have no authority to use budgeted
          funds for a particular item which will cost in excess
          of Five Million Dinars (5,000,000.00) or its equivalent
          in Foreign Exchange without first having obtained from
          the Operating Committee approval of an authorization
          for expenditure covering that particular item.

15.6 The authorization given by the Operating Committee for the
Drilling of any Well shall include approval of all necessary
expenditures required therefor and for completing, testing and
equipping that Well.

15.7 In an emergency, Operator shall have the right to incur
liabilities on behalf of the Parties without prior authorization
of the Operating Committee.  In that event, Operator shall take
such steps and make such expenditures on behalf of the Parties as
are necessary to protect the interests of the Parties and their
respective employees.  As promptly as possible, Operator shall
report such emergency and the action it has taken to the
Operating Committee.

15.8 No Well which is producing Hydrocarbons (or is capable of
but is not then producing Hydrocarbons) may be plugged and
abandoned without approval of the Operating Committee and the
Competent Authority.  If approval of the Operating Committee and
the Competent Authority is received to plug and abandon a Well,
that Well shall be plugged and abandoned by Operator at the
expense of the Joint Account.  However, if the Well was drilled
by SONATRACH pursuant to Article 13 and recoupment of penalty (if
applicable under Paragraph 13.6.A) has not been achieved, that
Well shall be abandoned at the sole cost and expense of
SONATRACH.

15.9 Except as provided in Article 13, all expenses, risks and
liabilities for Development and Exploitation of each Pool shall
be considered Joint Operations conducted at the joint expense of
the Parties in accordance with their Percentage Share of
Financing.

15.10     All payments which either Party is required to make
(except advances for cash calls of the Operator) shall be made
within thirty (30) Days following receipt of the invoice
requesting such payment.

15.11     In accordance with Annex "B", Operator shall keep
complete books and records of all Exploitation Costs incurred.

15.12     A Party shall be in default if it fails to advance to
Operator its Percentage Share of Financing of cash calls within
the time stated in Annex "B", or fails to pay when due its
Percentage Share of Financing of costs of the Joint Account.
That Party shall remedy its default by paying all amounts due,
plus interest thereon from the date such amount was due and
payable at the rate specified in Annex "B".
                           ARTICLE 16
                VALUATION OF LIQUID HYDROCARBONS


16.1 The quantities of Liquid Hydrocarbons delivered to ANADARKO
as Cost Recovery Liquid Hydrocarbons under Article 18 shall be
valued solely at the sales price of Liquid Hydrocarbons of
identical quality received by SONATRACH on the international
market (hereinafter referred to as the "Sales Price").

16.2 The calculation of the Sales Price applicable for each
Calendar Quarter shall be made on the basis of the average price
received by SONATRACH from sales of Liquid Hydrocarbons during
the three (3) months preceding the month in which the Notice
required by Paragraph 16.3 is made.  The sales to be taken into
consideration in the determination of the Sales Price shall be in
Foreign Exchange FOB at the Port of Loading and shall concern
comparable quantities of Liquid Hydrocarbons, after taking into
consideration adjustments for quality.  No "spot" sales or
contracts involving barter shall be used in the calculation of
the Sales Price.

16.3 The Sales Price referred to in Paragraph 16.2 above shall be
stated for a Calendar Quarter in a Notice delivered by SONATRACH
to ANADARKO at the latest within the first ten (10) Days of the
month preceding such Calendar Quarter.  The Sales Price thus
stated shall apply to Liquid Hydrocarbons taken in the Calendar
Quarter in question.  If such Notice is not delivered within that
time limit, the applicable price shall be that previously
calculated.  However, the Operating Committee may decide to
retain the Market Price applicable for the same period as
stipulated in Paragraph 16.4 herein.  If the new Sales Price
which should have been applied for the said Calendar Quarter is
set after the time limit, an adjustment to the valuation shall be
made by adjusting the quantity of Liquid Hydrocarbons to be taken
during the next Calendar Quarter.

16.4 If one Party believes that the Sales Price referred to in
Paragraph 16.2 differs in a significant manner and for a
significant period of time from the average of a basket of prices
of Liquid Hydrocarbons of the same quality as those Liquid
Hydrocarbons to be taken by ANADARKO (hereinafter referred to as
the "Market Price"), the Operating Committee shall determine the
price to be used for the valuation of Liquid Hydrocarbons.  For
the purpose of the composition of the basket of prices stated
above, and before Liquid Hydrocarbons are taken, the Operating
Committee shall select at least five (5) Liquid Hydrocarbons of
the same quality to determine the Market Price.

16.5 The quantities of Liquid Hydrocarbons to be taken by
ANADARKO during a given Calendar Year shall be calculated on a
provisional basis during the first fifteen (15) days of the month
of December preceding the applicable Calendar Year on the basis
of the elements agreed by the Parties under Paragraph 4.3 B.
Before the end of each Calendar Quarter of the Calendar Year in
question, these quantities shall be adjusted on the basis of
actual data supplied and arrived at by the Parties.  Before the
end of the first Calendar Quarter of the Calendar Year following
the Calendar Year in question, the quantities due to ANADARKO for
that Calendar Year shall be definitely determined.  Any
adjustments made shall apply to quantities of Liquid Hydrocarbons
to be taken during the following Calendar Quarter.
                           ARTICLE 17
               DISPOSITION OF LIQUID HYDROCARBONS


17.1 During the term of this Agreement, each Party shall have the
right to take, receive, export from Algeria, sell, dispose of,
and carry away all its share as stated in Paragraph 4.3 of all
Liquid Hydrocarbons produced and saved from each Pool.

17.2 As part of Joint Operations, Operator shall construct such
Liquid Hydrocarbon storage and handling facilities and evacuation
pipelines which are necessary to connect the respective delivery
facilities of each Pool to the main pipeline(s) of SONATRACH (or
its Affiliate).  All these facilities shall be approved
beforehand by the Operating Committee.  The outlet flange of each
evacuation pipeline at the main pipeline shall be the Point of
Delivery.

17.3 Costs and expenses necessary pursuant to Paragraph 17.2, and
those necessary for the maintenance and operation of those
pipelines and metering stations located upstream from the Point
of Delivery, shall be Joint Account expenses.

17.4 If quantities of Liquid Hydrocarbons as to which ANADARKO is
entitled from a discovered Pool do not have the same
characteristics as those to be delivered to ANADARKO at the Port
of Loading, then, before deliveries commence, the Parties shall
reach agreement as to the characteristics and quantities of
Liquid Hydrocarbons to be delivered by SONATRACH to ANADARKO in
substitution of those ANADARKO should be delivered.  The
quantities of Liquid Hydrocarbons stated above shall be
determined in accordance with an evaluation formula determined by
the Operating Committee.  That formula shall take into
consideration the difference in quality between the Liquid
Hydrocarbons from the Pools discovered and the Liquid
Hydrocarbons to be delivered by SONATRACH to ANADARKO.

17.5 If controls relating to production quotas are imposed such
that the Pools are restricted from being able to produce at their
Maximum Efficient Rate of production, SONATRACH agrees that the
reduction in the production of Liquid Hydrocarbons from said
Pools will not be greater than that imposed on the total
production of Liquid Hydrocarbon Pools of the same kind in
Algeria.  However, should the imposition of quotas for the
conservation of the production result in the said Pools being
produced at a rate below their Economic Limit, the Parties agree
to make every effort to ensure that such Pools are produced at
their Maximum Efficient Rate of production.
                           ARTICLE 18
          REIMBURSEMENT OF THE FIFTY ONE PERCENT SHARE
                      OF EXPLORATION COSTS


18.1 As reimbursement for fifty one percent (51%) of Exploration
Costs incurred, ANADARKO shall receive and SONATRACH commits
itself to deliver (or cause to be delivered) to ANADARKO, FOB at
the Port of Loading, a quantity of Liquid Hydrocarbons valued in
accordance with Article 16 and determined by application of the
provisions of subparagraph 4.3 B (herein referred to as "Cost
Recovery Liquid Hydrocarbons").

18.2 Deliveries of Cost Recovery Liquid Hydrocarbons shall be
made, subject to Paragraphs 18.3 and 18.4 below, from one or more
Pools developed and exploited jointly until ANADARKO has been
reimbursed fully for fifty one percent (51%) of all Exploration
Costs incurred.

18.3 The quantity of Cost Recovery Liquid Hydrocarbons shall be
determined by taking into consideration the legal amortization
rate specified in Article 54 of Law 86-14.

18.4 In determining the quantity of Cost Recovery Liquid
Hydrocarbons, the Parties agree as follows:

          A.   If the Operating Committee determines that a Pool
          would be commercially exploitable if fifty one percent
          (51%) of all Exploration Costs which (i) have not been
          reimbursed to ANADARKO at that time (herein referred to
          as "Unreimbursed Exploration Costs"); and (ii) are
          projected to be incurred by ANADARKO thereafter (herein
          referred to as "Projected Exploration Costs"), were
          charged as a burden against SONATRACH'S share of Liquid
          Hydrocarbons from that Pool, then the Cost Recovery
          Liquid Hydrocarbons shall be equal in value to:

                    1.   Unreimbursed Exploration Costs; and

                    2.   Projected Exploration Costs (subject,
               however, to adjustment based upon the sum of
               actual Exploration Costs incurred in the future),
               even if no further Commercial Discovery is
               achieved; or

          B.   If the Operating Committee determines that the
          Pool would be commercially exploitable only if
          Unreimbursed Exploration Costs and a portion of
          Projected Exploration Costs were charged as a burden
          against SONATRACH'S share of Liquid Hydrocarbons from
          that Pool, then Cost Recovery Liquid Hydrocarbons shall
          be equal in value to:

                    1.   Unreimbursed Exploration Costs; and

                    2.   The agreed portion of Projected
               Exploration Costs (subject, however, to adjustment
               based upon the sum of actual Exploration Costs
               incurred in the future).

               That portion of Exploration Costs not reimbursed
          out of Liquid Hydrocarbons from that Pool shall be
          carried forward for reimbursement as stated in
          subparagraph 18.4 F below; or

          C.   If the Operating Committee determines that the
          Pool would be commercially exploitable if all or a
          portion of Unreimbursed Exploration Costs, but none of
          the Projected Exploration Costs, were charged as a
          burden against SONATRACH'S share of Liquid Hydrocarbons
          from that Pool, then the Cost Recovery Liquid
          Hydrocarbons shall be equal in value to the agreed
          portion of Unreimbursed Exploration Costs.  That
          portion of Exploration Costs not reimbursed out of
          Liquid Hydrocarbons from that Pool shall be carried
          forward for reimbursement as stated in subparagraph
          18.4 F below; or

          D.   If the Operating Committee determines that the
          Pool is commercially exploitable if only fifty one
          percent (51%) of Exploration Costs incurred in respect
          of that Pool were charged as a burden against
          SONATRACH'S share of Liquid Hydrocarbons, then the Cost
          Recovery Liquid Hydrocarbons from that Pool shall be
          equal in value to fifty one percent (51%) of
          Exploration Costs incurred in respect of that Pool
          only.  That portion of Unreimbursed Exploration Costs
          from that Pool shall be carried forward for
          reimbursement as stated in subparagraph 18.4. F below;
          or

          E.   If the Operating Committee determines that a
          particular discovery of Liquid Hydrocarbons is
          commercially exploitable only if not burdened by
          charging SONATRACH'S share of Liquid Hydrocarbons from
          that Pool with a reimbursement obligation, then
          Unreimbursed Exploration Costs and Projected
          Exploration Costs which otherwise would be reimbursable
          to ANADARKO out of Liquid Hydrocarbons from that Pool
          shall be carried forward for reimbursement in the
          manner stated in subparagraph 18.4 F below; and

          F.   The following provisions shall be applicable to
          Exploration Costs which have not been reimbursed to
          ANADARKO from SONATRACH'S share of Liquid Hydrocarbons
          from one or more Pools:

                    1.   Until ANADARKO has received full
               reimbursement for fifty one percent (51%) of all
               Exploration Costs incurred, Exploration Costs
               which have not been reimbursed to ANADARKO when a
               new Pool is determined to be commercially
               exploitable shall be carried forward and
               consolidated for reimbursement to ANADARKO out of
               Liquid Hydrocarbons from that Pool and each Pool
               subsequently established; and

                    2.   During each annual meeting stated in
               subparagraph 5.9 A which occurs after the granting
               of the first Exploitation Licence, the Operating
               Committee shall make a determination as to whether
               the Pool(s) then under production (based upon the
               production performance of that or those Pools, the
               Sales Price or, if appropriate, the applicable
               Market Price of the Hydrocarbon reserves remaining
               in place, production rates greater than
               anticipated in the Development Plan for that or
               those Pools, and other economic factors) would
               remain commercially exploitable if the
               Unreimbursed Exploration Costs are reallocated and
               charged to SONATRACH'S share of Liquid
               Hydrocarbons from that or those Pools.  If the
               Operating Committee determines that a Pool(s)
               would remain commercially exploitable under the
               conditions stated above, the Operating Committee
               shall reach agreement as to the additional
               quantity of Cost Recovery Liquid Hydrocarbons.
               This method of reallocating Exploration Costs will
               also apply when the Operating Committee determines
               that a Pool's (or Pools') actual production
               performance is less than that which was estimated
               in the initial determination of its commerciality.

18.5 If the Representatives fail to reach unanimous agreement as
to any of the matters stated in Article 18, then the impasse
shall be resolved in accordance with Article 26.

                           NATURAL GAS
                                
                           ARTICLE 19
           PROVISIONS RELATING TO GASEOUS HYDROCARBONS


19.1 Associated Gas or Non-Associated Gas shall be used
preferentially for Petroleum Operations relating to the optimum
recovery of Liquid Hydrocarbons in the Pool discovered.  These
uses are to be reviewed and evaluated as a part of the
Development Plan established for each Pool discovered.
Associated or Non-Associated Gas shall have priority use for
Petroleum Operations in Pools discovered anywhere on the Contract
Area, for the purpose of Gas injection to improve production of
Liquid Hydrocarbons, or to produce or conserve Reservoir energy
necessary for Exploitation of Reservoirs.

19.2 If Natural Gas is discovered in quantities sufficient to
lead ANADARKO to believe that such discovery is or may be
commercially exploitable within the framework of Petroleum
Operations and/or for the extraction of Natural Gas Liquids
and/or for the export of surplus Natural Gas, ANADARKO shall
submit a Discovery Report to the Operating Committee.  Following
review of the Discovery Report, the Operating Committee shall
instruct the Technical Advisory Committee to study ANADARKO'S
proposals and report to it all possible economic alternatives
concerning that discovery.

19.3 Upon receipt of the Technical Advisory Committee's report,
the Operating Committee shall reach agreement as to whether a
commercially exploitable Pool has been discovered.  A Natural Gas
Pool shall be deemed to be commercially exploitable if the
proceeds of sale of the volume of Natural Gas that can be
produced are sufficient to cover Exploration and Exploitation
Costs, Transportation charges, Royalty, Taxes, the Bonus owed to
ANADARKO under Paragraph 19.4 A, and still yield a net profit.

19.4 If the Operating Committee agrees that a commercially
exploitable Gas Pool has been discovered, then:

          A.   SONATRACH shall deliver to ANADARKO, FOB at the
          Port of Loading, a quantity of Liquid Hydrocarbons
          equal in value to all Exploration Costs of ANADARKO in
          respect of that Natural Gas discovery, together with an
          additional volume of Liquid Hydrocarbons equal in value
          to a Bonus of one hundred and fifty percent (150%) of
          those Exploration Costs (herein referred to as
          "Bonus").  The delivery of Liquid Hydrocarbons to
          ANADARKO under this subparagraph shall be made within
          one (1) year following the date deliveries of Gas from
          the Gas Pool commence at the Point of Delivery.  The
          reimbursement of Exploration Costs to ANADARKO under
          this subparagraph will be made provided that the
          Exploration Costs associated with the Gas discovery
          were not added to reimbursable Exploration Costs under
          Article 18 of this Agreement; and

          B.   Natural Gas Liquids from the said discovered Pool
          and resulting from Hydrocarbons processing by the
          Parties on the site of said Pool or on another site
          agreed by the Parties shall be distributed under the
          provisions of Paragraph 4.3 of this Agreement.

l9.5 If the Parties further agree to jointly export the surplus
Natural Gas, they shall enter into a protocol agreement under
which a jointly held company ("societe d'economie mixte") ruled
by Algerian law will be created, of which ANADARKO shall have a
participation of forty-nine percent (49%) and SONATRACH will have
a participation of fifty-one percent (51%).

          conducting Petroleum Operations; and

          B.   All temporary or permanent buildings needed to
          house personnel engaged in Petroleum Operations, to
          store or protect Movable Property from environmental
          elements, and offices and housing for Operator's
          personnel (herein referred to as "Immovable Property").

20.2 The purchase of Immovable Property situated in Algeria shall
be subject to the requirements of applicable Laws.

20.3 All agreements for the purchase or rental of any single item
of Movable Property or Immovable Property for use in Joint
Operations chargeable to the Joint Account and whose anticipated
cost will exceed Five Million Dinars (5,000,000.00), or its
equivalent in Foreign Exchange, shall be previously submitted to
the Operating Committee for approval.

20.4 In the purchase or rental of Movable Property for use in
Algeria, Operator shall give preference to Algerian manufactured
Movable Property, provided:

          A.   The quality of the particular product is
          acceptable based upon standards and codes recognized in
          Algeria and internationally which will be as strict as
          those set or established by the American Petroleum
          Institute (API):

          B.   The cost of the particular product is competitive
          with the prevailing rates for Movable Property
          delivered in Algeria and proposed by Non-Algerian
          suppliers; and

          C.   The Algerian supplier can deliver the particular
          product by the time and in the quantity required by
          Operator in comparison with the time and quantities
          proposed by non-Algerian suppliers.

20.5 Operator is authorized to select, in accordance with the
criteria stated in Paragraph 20.7, engage and entrust to
contractors the execution of works within Petroleum Operations.

20.6 All agreements to be entered into by Operator and its
contractors which contemplate an expenditure chargeable to the
Joint Account greater than Five Million Dinars (5,000,000.00), or
its equivalent in Foreign Exchange, shall be previously submitted
to the Operating Committee for approval.

20.7 Operator shall, in selecting contractors, give preference to
SONATRACH and its Affiliates, and to Algerian business persons or
entities, provided that in each instance operator is reasonably
satisfied with their ability to perform the work entrusted to
them and provided that their fees, time, terms and conditions are
competitive with those of other contractors who submit tenders
for such work.  Particularly, the competitive criteria include
the contractor's experience, the condition and availability of
its equipment, the unique capabilities of the contractor's
service and/or equipment and the contractor's compliance with
equipment specifications and performance standards recognized in
the petroleum industry.

20.8 The fixed assets resulting from Petroleum Operations shall
be owned exclusively by SONATRACH, except for the Movable
Property and Immovable Property rented or purchased and imported
by ANADARKO in its own name or by its contractors in their name.
ANADARKO shall have free use of the foregoing property, without
cost, which property shall be under its responsibility as long as
ANADARKO conducts Petroleum Operations under this Agreement.

20.9 The Movable Property purchased and/or imported into Algeria
by ANADARKO in SONATRACH'S name and which it uses in conducting
Petroleum Operations shall pass to SONATRACH when purchased or,
if applicable, when imported into Algeria.  ANADARKO shall have
free use of the foregoing property, without cost, which property
shall be under its responsibility as long as ANADARKO conducts
Petroleum Operations under this Agreement.

24.3 The Parties agree that SONATRACH'S right of preemption under
Decree No. 87-158 in respect of contemplated transfers by
ANADARKO to Non-Affiliates shall be implemented according to the
following procedure:

          A.   ANADARKO shall give notice to SONATRACH of its
          desire to make the transfer, stating the name of the
          Non-Affiliate(s), the price and a summary of all other
          terms and conditions acceptable to ANADARKO;

          B.   Within ninety (90) Days of receipt of the Notice
          mentioned in Paragraph A above, SONATRACH shall give
          Notice to ANADARKO indicating whether it wishes to
          exercise its preemption right based upon the price and
          the other conditions contained in the Notice mentioned
          in Paragraph A above, and whether or not the Competent
          Authority will approve the preemption purchase by
          SONATRACH;

          C.   If SONATRACH exercises its preemption right then:

                    1.   It will be deemed that the Competent
               Authority has approved the transfer to SONATRACH
               from ANADARKO; and

                    2.   Not later than thirty (30) Days from the
               date ANADARKO receives SONATRACH'S Notice, the
               Parties shall enter into such agreements as are
               necessary to finalize the transfer; and

          D.   If SONATRACH does not exercise its preemption
          right, ANADARKO shall have the right to transfer to the
          Non-Affiliates all or part of ANADARKO'S rights and
          obligations stated in its Notice, on terms and
          conditions no less favorable to ANADARKO as the terms
          and conditions offered to SONATRACH.

24.4 If a transfer is made, the transferee shall succeed to the
rights and obligations of ANADARKO, to the extent of the portion
of the Percentage Share of Financing and Percentage Interest
received.  No such transfer shall modify the rights and
obligations of SONATRACH.
     ANADARKO and its transferees shall be jointly and severally
responsible to SONATRACH for all obligations arising from this
Agreement.  It is agreed that SONATRACH shall only have to deal
with ANADARKO who shall represent each of the transferees and
that ANADARKO alone shall be responsible for the execution of all
obligations arising under this Agreement.  Each of the
transferees shall, to that effect, appoint ANADARKO as its
representative with SONATRACH and shall grant to it powers to
take all measures necessary to the execution of this Agreement.

24.5 The substitution or total or partial transfers by SONATRACH
of its rights and obligations under this Agreement to one of its
Affiliates shall not modify or prejudice the rights and
obligations of the other Party to this Agreement.

          able to make a call for funds; and

          D.   Not cause any interruption in the performance of
          obligations under this Agreement for the sole reasons
          of the Conciliation process.

entrusted, the Conciliation Board must take into account:

          A.   If both Parties accept the recommendation, they
          will implement the means which will enable them to

          B.   If one of the Parties rejects the recommendation,
          that Party shall notify the Chairman so that the
          Conciliation Board may give official notice to the
          Parties that the attempt of Conciliation has failed.

          C.   It shall be possible to submit the dispute to the
          competent Algerian jurisdiction according to Article 63
          of Law 86-14, if, at the expiration of sixty (60) Days
          from the recommendation, the recommendation has not
          been expressly accepted by the Parties.

26.8 The recommendation of the Conciliation Board is of a
confidential nature and it cannot be released, produced nor

the other Party or by a Third Party without the specific consent
of all Parties to this Agreement.  The confidential nature of the
recommendation cannot be asserted if the competent jurisdiction

          rate of the Central Bank of Algeria (B.C.A.) for the
          preceding month, to three decimal places, rounded down
          if it is under the number five and up if it is over

          12.  If the Seismic Processing Center is not imported
          and operational in Algeria within six (6) months
          following the Effective Date of the Agreement, ANADARKO
          will, within ten (10) Days from expiration of that
          period, call a meeting of the Operating Committee to
          seek a solution to the problem causing the delay.
          Provided the Operating Committee reaches agreement as
          to a solution, ANADARKO shall have a maximum time of
          three (3) months from the date of that meeting within
          which to import and make the Seismic Processing Center
          operational.

13. In the case one of the two following situations occurs:

          A.   Three (3) months after the Effective Date of the
          Agreement SONATRACH and ANADARKO fail to reach final
          agreement as to the specific terms and provisions
          concerning the Seismic Processing Center Agreement and
          the Operating Committee agrees that all possible means
          of reaching final agreement have been exhausted and the
          principles contained in this Annex have not been
          violated by either Party; or

          B.   ANADARKO fails to import and have the Seismic
          Processing Center operational pursuant to Paragraph 12
          above, whichever event first occurs, then ANADARKO
          shall advance the sums necessary for SONATRACH to
          execute, for ANADARKO'S account, the obligations stated
          in Paragraph 3 above which ANADARKO is unable to
          perform as part of the initial Exploration Work Program
          approved by the Operating Committee.
                            ANNEX "E"
                        TAKING PROCEDURE
                                

                            ARTICLE 1
                        LOADING LIABILITY
                                

SONATRACH shall be liable to ANADARKO for due execution of all
ship loading operations for which it is responsible under the
Agreement and this Annex.  On the other hand, all other purely
port operations shall be the direct responsibility of the partner
or his representatives.

                            ARTICLE 2
           QUARTERLY LOADING PROGRAM AND APPORTIONMENT

     On the basis of the estimated quantities of Liquid
Hydrocarbons which are expected to be at ANADARKO'S disposal,
eighty-five (8) days before the beginning of each Calendar
Quarter, ANADARKO shall give Notice to SONATRACH of the monthly
quantities it expects to take during each Calendar Quarter.
     Within fifteen (15) days of the receipt of the above
mentioned Notice, SONATRACH shall notify ANADARKO either of its
agreement or of the amendments SONATRACH wishes to include in the
program proposed by ANADARKO.

                            ARTICLE 3
         MONTHLY LOADING PROGRAM AND NOMINATION OF SHIPS

3.1  Thirty (30) days before the beginning of each month of the
     quarterly loading program, ANADARKO shall notify SONATRACH
     of the loading program it wishes to follow during that
     month.  That Notice shall indicate the quantity of Liquid
     Hydrocarbons to be loaded-within ten percent (10%)-onto each
     ship and the Expected Time of Arrival ("ETA") for each ship.
     Within five (5) days following receipt of that Notice,
     SONATRACH shall inform ANADARKO if it can or cannot accept
     the ETA proposed by ANADARKO.  In the event of
     non-acceptance, SONATRACH shall set loading dates as close
     as possible to the ones proposed by ANADARKO.

3.2  ANADARKO shall notify SONATRACH ten (10) days in advance of
     the firm date ("Firm Date") of the ship's arrival, of its
     name, principle dimensions, cargo load capacity, the port(s)
     of discharge of cargo and the distribution of the usual
     loading documents.

     Unless the Parties agree otherwise, the Firm Date so
     announced must not be postponed more than two (2) days from
     the date previously set in the monthly loading program
     established in accordance with the provisions of Paragraph
     3.1 of this ANNEX.

3.3  ANADARKO shall take measures to ensure that the captain of
     its ship notifies SONATRACH'S representative at the Port of
     Loading of the ship's ETA at the Port of Loading, as
     follows:

          A.   A first Notice shall be sent either as soon as the
          ship casts off from the last port of call, if that port
          is no more than seventy-two (72) hours away from the
          Port of Loading (which will have been determined by
          SONATRACH) or, if it is not the case, seventy-two (72)
          hours prior to the ship's ETA; then

          B.   A second Notice shall be sent forty-eight (48)
          hours prior to the ship's ETA; and finally,

          C.   A third Notice shall be sent twenty-four (24)
          hours prior to the ship's ETA.

3.4  ANADARKO may substitute a ship previously nominated
     according to the provisions of this Article for another ship
     of the similar type and capacity.

     ANADARKO shall notify SONATRACH of any substitution as soon
     as possible, and at least seventy-two (72) hours prior to
     the ETA of the ship initially nominated.

3.5  Subject to thirty (30) days' prior Notice, SONATRACH
     reserves the right to request the taking of Liquid
     Hydrocarbons as soon as the volumes in storage which are due
     to ANADARKO have reached 50,000 metric tons.

                            ARTICLE 4
                             LOADING


4.1  SONATRACH'S representative will load the ship at the berth
     assigned to it.  The berth shall be free upon the ship's
     arrival and shall permit the ship to enter, exit and anchor
     in security.

4.2  When the ship arrives at a Port of Loading or in a zone
     outside the port, the ship's captain shall notify
     SONATRACH'S representative by letter, telex, or radio that
     the ship is ready to receive the quantity of Liquid
     Hydrocarbons scheduled for that ship, whether the berth is
     free or not.

4.3  If, upon the ship's arrival, the ship is led without delay
     to the berth, the Notice specified in Paragraph 4.2 above
     shall be deemed to have been given as soon as the ship has
     completed mooring.

4.4  If the ship arrives at the Port of Loading within twelve
     (12) hours prior to or after the Firm Date, the lay day
     period shall start either six (6) hours following receipt of
     the Notice, or at the start of loading operations, provided
     it begins before the end of this six (6) hour period.  Any
     other delay caused by the ship shall be added to that six
     (6) hour period.

4.5  If the ship arrives at the Port of Loading more than twelve
     (12) hours prior to the Firm Date, SONATRACH'S
     representative shall cause the loading operations to proceed
     as soon as possible, taking into consideration the
     requirements of the overall loading program of other ships.

     In no case shall SONATRACH'S representative be bound to
     accept the Notice more than six (6) hours prior to the
     expected loading time.  The lay days shall be calculated
     according to the provisions of Paragraph 4.4 above.

4.6  If the ship arrives at the Port of Loading more than twelve
     (12) hours after the Firm Date, SONATRACH'S representative
     shall proceed to the loading operations as soon as possible,
     taking into consideration the overall loading programs for
     other ships and its available supply of Liquid Hydrocarbons.

     The lay day period shall start at the first of the following
     hours:

          A.   Either six (6) hours after the Notice given under
          Paragraph 4.2 above has been declared acceptable by
          SONATRACH'S representative; or

          B.   At the start of loading operations, if loading
          begins less than six (6) hours after acceptance of that
          Notice.

4.7  The lay days shall cease when the loading hose pipes are
     disconnected and the necessary documents are received on
     board.

4.8  The time allotted for the loading shall be equal to one-half
     (1/2) the time stated in the latest edition of the WORLDWIDE
     TANKER NOMINAL FREIGHT SCALE (hereafter referred to as
     "WORLDSCALE") in effect on the day loading is completed, for
     ships of similar type and capacity.

4.9  The ship shall leave its berth upon completion of the
     loading operations.  Any loss or damage suffered by
     SONATRACH or its representative due to the ship's failure to
     quickly leave its assigned berth, including delays suffered
     by other ships waiting for their turn to load, shall be the
     responsibility of ANADARKO.

4.10 All piloting, mooring, "lamanage," and deballasting costs
     shall be borne by the ship.  If, upon SONATRACH'S
     representative's request, there is a change of berth during
     loading operations, the costs corresponding to that change
     shall be borne by SONATRACH.

                            ARTICLE 5
                            DEMURRAGE

5.1  Subject to compliance with the Notice provisions of
     Paragraphs 3.2 and 3.3, SONATRACH will pay ANADARKO, for any
     ship not loaded within the lay day period determined
     according to the provisions of Article 4 above, demurrage
     for the number of hours or portions thereof in excess these
     periods.

5.2  The amount of demurrage shall be calculated at the rate in
     effect as stated in the latest edition of WORLDSCALE, for a
     ship of the same type and capacity transporting the same
     type of Liquid Hydrocarbons.  This rate shall be modified by
     the Average Freight Rate Assessment percentage (hereafter
     referred to as "AFRA") in effect on the day of completion of
     loading operations and applicable to that same category of
     ship.

5.3  If ANADARKO presents a ship for loading whose size and
     Liquid Hydrocarbon tonnage capacity is greater than agreed,
     the demurrage shall be calculated at the Worldscale rate
     corresponding to the said tonnage to which a five percent
     (5%) allowance in respect of fuel and consumables shall be
     added.  The resulting rate shall be modified by the AFRA
     percentage in effect on the date of completion of loading
     operations and applicable to the category of ship with the
     agreed tonnage, to which the said five percent (5%)
     allowance shall be added.

5.4  No demurrage shall be paid by SONATRACH to ANADARKO if the
     difficulty or delay in delivering Liquid Hydrocarbons is due
     to Force Majeure.

5.5  All claims by ANADARKO for the payment of demurrage must be
     received by SONATRACH within three (3) months after the date
     of the bill of lading.  The claim shall include, in addition
     to all the other documents in support of the claim, an
     original invoice and four duplicate copies.  Beyond this
     deadline, the claim shall not be taken into consideration.

                            ARTICLE 6
                 DELIVERY AND LOADING CONDITIONS

     Liquid Hydrocarbons shall be delivered by SONATRACH and
     taken by ANADARKO FOB port of loading.
     The features of the ports of loading shall be communicated
     to ANADARKO before taking begins.

                            ARTICLE 7
                         FREIGHT CONTROL

7.1  The quantity of Liquid Hydrocarbons delivered to ANADARKO
     will be volumetrically determined during loading operations
     based on measurements of the onshore tanks used to load the
     ship.  The volumes will be corrected to a temperature of 15
     C using appropriate conversions, the deduction being made
     for possible BSW.

7.2  ANADARKO will be able to designate, on condition of first
     obtaining SONATRACH'S agreement (which agreement will not be
     unreasonably withheld), a representative to witness the
     inspection of the quantity of Liquid Hydrocarbons during
     loading operations of each ship.  To that end, SONATRACH
     shall place at ANADARKO's representative's disposal a copy
     of the quantity calculations and any other information
     relating to Liquid Hydrocarbons delivered to ANADARKO.  In
     this case, the quantity of Liquid Hydrocarbons received
     which will appear on the bill of lading will be that which
     was determined jointly by SONATRACH and ANADARKO's
     representative.

7.3  SONATRACH shall give to ANADARKO a certificate indicating
     the quantity of Liquid Hydrocarbons delivered to ANADARKO.
     The certificate shall not be contestable after thirty (30)
     days following the date of the bill of lading.

7.4  In case of objection by ANADARKO within the time period
     stated in Paragraph 7.3 above, Article 26 of the Agreement
     will be applied.

7.5  The quality of the Liquid Hydrocarbons shall be determined
     from representative samples taken from the onshore tanks.
     One of these samples shall be sealed and put on board the
     ship for ANADARKO'S use.  Another sealed sample shall be
     kept by SONATRACH for thirty (30) days from the date of the
     bill of lading.

7.6  The quality testing of samples shall take place, except if
     otherwise agreed by the Parties, according to the most
     recent methods of the American Society for Testing Materials
     (ASTM).  The sulfur content and water and sediment content
     (BSW) will be determined according to ASTM-D-129 and
     ASTM-D-96 respectively.
