Item 1.  Business

         Magellan  Petroleum  Corporation  (the  "Company" or "MPC") is engaged,
directly and through its majority-owned  subsidiary,  in the sale of oil and gas
and the  exploration  for and  development of oil and gas reserves.  At June 30,
1999,  the  Company's  principal  asset  was a  50.9%  equity  interest  in  its
subsidiary,  Magellan Petroleum Australia Limited ("MPAL"),  which has one class
of stock that is publicly held and traded in Australia.

         MPAL owns interests in various oil and gas properties in Australia, the
United States and Belize,  Central America.  MPAL's major Australian  assets are
two  petroleum  production  leases  covering the Mereenie oil and gas field (35%
working  interest) and one petroleum  production  lease covering the Palm Valley
gas field (50.8% working interest). Both fields are located in the Amadeus Basin
in the  Northern  Territory  of Australia  ("Northern  Territory").  Santos Ltd.
("Santos"), a publicly owned Australian company, owns a 48% interest in the Palm
Valley  field,  a 65%  interest  in the  Mereenie  field  and  18.2%  of  MPAL's
outstanding stock. Boral Limited, a publicly owned Australian  company,  owned a
17.1% interest in MPAL's outstanding stock at June 30, 1999.

         The Company has a direct 2.67% carried  interest in the  Kotaneelee gas
field in the Yukon  Territory  of  Canada.  The  Company  has not  received  any
revenues from this field to date. See Item 3 - Legal  Proceedings.  In addition,
the Company has a 3% working  interest in a Belize  project (in which MPAL has a
20% working interest) and a 20% working interest in two wells in Texas.

         (a)      General Development of Business.

                  Operational  Developments  Since  the  Beginning  of  the Last
                  Fiscal Year.

AUSTRALIA

Mereenie

         MPAL (35%) and  Santos  (65%),  the  operator,  (together  known as the
Mereenie  Participants)  own the Mereenie  field which is located in the Amadeus
Basin of the Northern  Territory.  MPAL's share of production  from the field is
subject  to net  overriding  royalties  aggregating  3.0625%  and the  statutory
government  royalty of 10%. MPAL's share of the Mereenie field proved  developed
oil reserves was approximately 730,000 barrels at June 30, 1999.

         The field was producing about 1,700 (MPAL share - 595) barrels of crude
oil per day ("bpd") at June 30, 1999. During 1999, MPAL's share of oil sales was
236,000  barrels and 3.4 billion  cubic feet ("bcf") of gas sold from 41 oil and
gas wells. The oil is transported by means of a 167 mile eight-inch oil pipeline
from the field to the Brewer Estate industrial park near Alice Springs.  Most of
the oil is then  shipped  south  approximately  950  miles by rail and road to a
refinery in the Adelaide area. The cost of transporting  the oil to the refinery
is being borne by the producers.  The Mereenie  Participants  are also providing
Mereenie gas in the Northern Territory to the Power and Water Authority ("PAWA")
and Gasgo  Pty.  Ltd.,  a company  it wholly  owns,  for use in Darwin and other
Northern Territory centers. See "Gas Supply Contracts".

         During 1999, the Mereenie  Participants  had been  negotiating  for the
sale of Liquid  Petroleum  Gas from the field to a purchaser but the project was
terminated after it was determined that it was uneconomic.

Palm Valley

         MPAL has a 50.8% interest in and is the operator of the Palm Valley gas
field which is located in the Northern  Territory.  Santos,  the operator of the
Mereenie field, owns a 48% interest in Palm Valley.  Ten wells have been drilled
in the field,  five of which are currently  connected to the gas treatment plant
and are flowed at maximum  deliverability  levels to meet the Alice  Springs and
Darwin supply  contracts  with PAWA. See "Gas Supply  Contracts".  During fiscal
1999,   MPAL's   share  of  gas  sales  was  3.7  bcf.   In  order  to  increase
deliverability,  field  compression  began  in  November  1996  with  two 400 HP
compressors.  A third 800 HP compressor was installed  during fiscal 1999.  MPAL
has recommended  that four additional wells be drilled at Palm Valley to improve
the field's production  capacity.  Under the gas supply agreement with PAWA, the
costs  of  these  wells  are   reimbursed   by  PAWA  and,   consequently,   the
recommendation is under review by PAWA's consultants.


<PAGE>

         MPAL's  share of Palm  Valley  production  revenues is subject to a 10%
statutory government royalty and net overriding royalties aggregating 4.2548%.

Gas Supply Contracts

         In 1983,  the Palm  Valley  Participants  commenced  the sale of gas to
Alice Springs under a 1981 agreement.  In 1985, the Palm Valley Participants and
Mereenie  Participants  signed agreements for the sale of gas to PAWA for use in
PAWA's Darwin generating station and at a number of other generating stations in
the  Northern  Territory.  The gas is being  delivered  via the 922 mile Amadeus
Basin to Darwin gas pipeline which was built by an Australian consortium.  Since
1985, there have been several additional contracts for the sale of Mereenie gas.
The  following  is a  summary  of MPAL's  interest  in the Palm  Valley  and the
Mereenie gas supply contracts:

</TABLE>

         Under the 1985  contracts,  there is a difference in price between Palm
Valley  gas and most of the  Mereenie  gas for the first 20 years of the 25 year
contracts  which  takes  into  account  the  additional  cost  to  the  pipeline
consortium  to build a spur line to the Mereenie  field and increase the size of
the pipeline from Palm Valley to Mataranka.

         In consideration for the Palm Valley  Participants  forgoing 20% of the
Amadeus Basin to Darwin gas supply  contract during the first 20 contract years,
Mereenie  Participants  made  a  payment  to the  Palm  Valley  Participants  to
partially  compensate the Palm Valley  Participants  for the reduced net present
value of the future gas sales  revenues which were postponed from contract years
1 to 20 to contract  years 21 to 26. The  agreement  also provides that when the
Mereenie  Participants sell any additional gas from the Mereenie field, the Palm
Valley  Participants are entitled,  as additional  consideration,  to 35% of the
revenues  from the first 38 bcf (MPAL share - 19.5 bcf) of gas sold. At June 30,
1999, the balance of the Mereenie  Participants  gas subject to this entitlement
was 9.7 bcf (MPAL share - 4.8 bcf).


<PAGE>


Dingo Gas Field

         MPAL has a 34.3%  interest  in the Dingo gas field  which is held under
Retention  License 2 and is subject  to  renewal  in 2003.  The Dingo gas field,
which  is  located  in  the  Amadeus  Basin  in  the  Northern  Territory,   has
approximately 25 bcf of presently proved and recoverable  reserves based on four
delineation  wells. Dingo 2 and Dingo 3 wells are estimated to have the capacity
of producing a combined rate of 5 million  cubic feet  ("mmcf") per day.  MPAL's
share of  potential  production  from  these  permit  areas is  subject to a 10%
statutory government royalty and overriding royalties aggregating 2.5043%.

Ngalia Basin

         MPAL had a 40%  interest  in permit  EP-15 in the  Ngalia  basin in the
Northern Territory which expired during May 1999. During July 1998, the Newhaven
well was plugged and  abandoned.  MPAL's  share of the drilling  costs  incurred
through June 30, 1998 were  included in  exploratory  and dry hole costs for the
1998 fiscal year. The costs to drill the well subsequent to June 30, 1998 in the
amount of $316,000  are  included in  exploratory  and dry hole costs for fiscal
1999.

Northern Surat Basin

         During  fiscal  1998,  MPAL  sold  its  15.625%  interest  in ATP  378P
Queensland,  Australia to its partner,  Santos. The $636,000  difference between
the carrying  cost and the sale price was included in loss on the sale of assets
for the 1998 fiscal year.

Surat Basin

         During the 1998 fiscal  year,  MPAL earned a 17% interest in Block D of
ATP 244P in  Queensland  by  completing a pilot  seismic  reprocessing  program.
During the 1999 fiscal year, MPAL abandoned its interest in the permit.

         During  fiscal  1998,  MPAL  earned  a 15%  interest  in  ATP  626P  in
Queensland. During fiscal 1999, MPAL relinquished its interest in the permit.

Timor Sea

         During April 1998,  MPAL acquired a 5% interest in  Exploration  Permit
WA-199-P in the  Bonaparte  Basin in the Timor Sea offshore  Western  Australia.
MPAL  earned its  interest  in the permit by funding 10% of the cost of drilling
the Kittiwake-1  well which was a dry hole.  MPAL's cost of the well was written
off in the fourth quarter of fiscal 1998 and was included in exploratory and dry
hole costs.  MPAL relinquished its interest in the permit during the 1999 fiscal
year.

Browse Basin

         During the 1999  fiscal  year,  MPAL was  granted a 17.5%  interest  in
exploration permits WA-281-P, WA-282-P and WA-283-P in the Browse Basin offshore
Western Australia. During the 1999 fiscal year, MPAL spent approximately $67,000
toward the Year 1 work obligations. MPAL's share of the work obligations for the
three permits is as follows:

                       WA-281-P        WA-282-P        WA-283-P          Total

Carnarvon Basin

         MPAL earned a 15% interest in  exploration  permits  TP/12 and EP398 in
the Carnarvon  Basin  offshore  Western  Australia by funding 30% of the cost of
drilling the Springbok-1  well. The  Springbok-1  well was plugged and abandoned
during August 1998.  MPAL's cost of drilling the well was written off during the
first quarter of fiscal 1999.



<PAGE>


         During April 1999, MPAL was awarded permit  WA-291-P,  offshore Western
Australia in the Carnarvon  Basin. The minimum  expenditure  obligations for the
first three year period totals $347,000. The discretionary  commitment for years
4-6 totals approximately $4.8 million.

Maryborough Basin

         MPAL holds a 98%  interest in  exploration  permit ATP 613P,  a 670,000
acre block, in the Maryborough Basin in Queensland, Australia. A third party has
agreed to drill an exploration  well in exchange for an approximate 50% interest
in the permit. The well will be drilled during the 2000 fiscal year.

Cooper Basin

         During April 1999,  MPAL (50%) and its partner Beach  Petroleum NL were
successful in bidding for two  exploration  blocks in South  Australia's  Cooper

Baca County, Colorado

         MPC (10%) and MPAL  (90%)  participated  in an  exploration  program in
Colorado.  During 1995, MPAL commenced a three well drilling program.  All three
wells  were dry  holes.  During  fiscal  1995 and 1996,  the  Company  wrote off
$809,000 and $1,691,000 in costs, respectively.  During fiscal 1997, the Company
drilled a fourth well which was a dry hole and all of the remaining costs of the
project,  which totaled  $3,008,000,  were written off. During fiscal 1999, MPAL
spent approximately $16,000 on the project and it is allowing most of the leases
to expire.

Tapia Canyon, California

         Effective December 1, 1997, MPC acquired an 18% interest in a heavy oil
recovery  project  in  Tapia  Canyon,   California.   Because  the  Company  was
dissatisfied  with the  program to develop the field  reserves,  the Company has
sold its  interest for its  approximate  cost of $101,000  effective  August 31,
1999.

Stephens County, Texas

         During  fiscal  1999,  MPC  participated  (20%) in the  drilling of the
Puckett No. 1 well which is presently  suspended.  There are  indications of oil
and additional work will be performed  during  September 1999.  During late June
1999,  MPC also  participated  (21.4%) in the  drilling  of the Smith No. 1 well
which also has  indications  of oil.  MPC's  capitalized  costs at June 30, 1999
totaled $71,000.

BELIZE

Southern Offshore Block PSA

         During  March 1998,  MPC (3%),  MPAL (20%) and the other joint  venture
participants  entered into a new Production  Sharing  Agreement ("PSA") with the
Government of Belize.  The new Southern  Offshore Block PSA ("SOB PSA") combines
most of the blocks previously  included in the Gladden PSA and the Block 13 PSA,
and totals approximately  893,000 acres. The work obligations of the new PSA are
as follows: Year 1 - $100,000, Year 2 - $300,000, Year 3 - $3,000,000 and Year 4
- -  $150,000.  The  participants  in the PSA have been  seeking  partners  in the
venture. The first year obligations have been completed and the participants are
negotiating with the Government of Belize to reduce the Year 2 obligations.

Gladden Basin PSA/Block 13 PSA

         During  1997, the Gladden No. 1 well was plugged and  abandoned and the
Company's  cost of the well was written off.  During March 1998,  this block was
consolidated into the SOB PSA.

         MPC and MPAL were also  participants in a Production  Sharing Agreement
("Block 13 PSA") offshore Belize  adjoining the western and southern  boundaries
of the Gladden PSA. The Block 13 PSA covered approximately 788,000 acres. During
March 1998, this block was consolidated into the SOB PSA.

CANADA

         The Company  owns a 2.67%  carried  interest in a lease  (31,885  gross
acres, 850 net acres) in the southeast Yukon Territory,  Canada,  which includes
the Kotaneelee gas field. Anderson Oil & Gas, Inc., ("Anderson") is the operator
of this partially developed field which is connected to a major pipeline system.
Two wells are currently producing gas from the field approximately 60-65 mmcfd.

         Although   production  at  the  Kotaneelee  field  commenced  in  1979,
sustained  production  from the field did not begin until February  1991.  Total
production from the field, according to government reports, has been as follows:

         In a 1989  application to the National Energy Board, a reserve study by
the then operator  estimated gas in place at 1.6 trillion cubic feet with proved
and probable recoverable reserves of 781 bcf.

         The operator has not permitted the Company  access to detailed  pricing
and volume information,  citing the litigation regarding the field. See Item 3 -
Legal  Proceedings  for a discussion  of litigation  relating to the  Kotaneelee
field which may affect the status of the carried  interest and the amount of the
carried interest account.

         The Company is not  entitled  to any  revenue  from the field until the
working  interest owners recover their costs.  The operator last reported to the
Company  unrecovered  development  costs totaling  approximately  Cdn.$8,873,000
(Company  share -  U.S.$159,000)  at May  31,  1999.  The  amount  of  remaining
recoverable  costs  is one of  the  issues  being  contested  in the  Kotaneelee
litigation.  The Company  claims,  and the defendants  deny, that the defendants
have made  improper  charges to the carried  interest  account and one defendant
(Amoco Canada Oil and Gas) maintains that the carried interest account should be
charged  additional  amounts  for gas  processing  fees.  Amoco  claims that the
remaining costs to be recovered at February 28, 1999 were Cdn.$77,983,000.


<PAGE>

         Projections by the operator  indicate that the carried interest account
may  reach  payout  status  prior to  December  1999.  However,  there can be no
assurances that payout will occur within that time frame,  inasmuch as there are
uncertainties as to production  levels, gas pricing,  field operating  expenses,
additional capital expenditures and the impact of the Kotaneelee litigation.

         For financial  statement  purposes in fiscal 1987 and 1988, the Company
wrote down its Canada cost  center  which  included  the  Kotaneelee  field to a
nominal value because of the uncertainty as to the date when sales of Kotaneelee
gas might begin and the  immateriality  of the carrying value of the investment.
Although the field is now producing and payout may occur by December  1999,  the
Company  has not yet  classified  its share of the  Kotaneelee  gas  reserves as
proved  because  the gas field is still the subject of  litigation.  The Company
will  reclassify  the reserves at the  Kotaneelee  field as proved when there is
greater assurance as to the timing and assumptions regarding the investment.

         (b)      Financial Information about Industry Segments.

                  Since the Company is engaged in only one industry, namely, oil
and  gas  exploration,  development,  production  and  sale,  this  item  is not
applicable to the Company.

         (c)      (1)     Narrative Description of the Business.

                  The Company was  incorporated in 1957 under the laws of Panama
and was  reorganized  under the laws of Delaware in 1967. The Company is engaged
in the  exploration  for, and the development and production and sale of oil and
gas  reserves  in the  United  States,  Canada,  and  Belize  and,  through  its
subsidiary MPAL, in Australia, the United States and Belize.

         (i)      Principal Products.

                  MPAL has an  interest  in the Palm Valley gas field and in the
Mereenie oil and gas field.  See Item 1(a) - Australia - for a discussion of the
oil and gas production from the Mereenie and Palm Valley fields. The Company has
a direct 2.67% carried interest in the Kotaneelee gas field in Canada.

         (ii)     Status of Product or Segment.

                  See Item 1(a) -  Australia  -  for a discussion of the current
and future operations of the Mereenie and Palm Valley fields in Australia.

                  Held.

                  In  Australia,   the  Company  has   interests   directly  and
indirectly  through its  subsidiaries in the following  permits.  Permittees are
required to carry out agreed work and expenditure programs.

                  In 1981, the Northern  Territory issued Petroleum Leases No. 4
and No. 5 which cover the Mereenie oil and gas field to MPAL's subsidiaries.  As
part of the lease conditions, MPAL and its Mereenie partners agreed to construct
an oil refinery near Alice Springs,  if it were  determined that such a refinery
is  economically  feasible.  MPAL  believes  that the oil refinery  would not be
economically viable under current market conditions,  and the Northern Territory
has not raised any current  objection  to this  conclusion.  In the event that a
refinery  becomes  economically  viable  and  the MJV  does  not  construct  the
refinery,  MPAL and its partners will be required to pay the Northern  Territory
liquidated  damages  based on the value of the crude oil produced from the lands
under  lease.  The  amount to be paid to the  Territory  is an amount per barrel
which is the  greater of (a)  A.$3.00  per barrel or (b) A.$2.00 per barrel plus
10% of the  amount by which  the  market  price of  Mereenie  crude oil  exceeds
A.$27.50. Production is subject to a statutory 10 percent royalty payable to the
Northern Territory.

                  In 1982 the Northern  Territory  granted Petroleum Lease No. 3
for the Palm Valley gas field to a MPAL  subsidiary.  Production is subject to a
statutory 10 percent royalty payable to the Northern Territory.

                  The above leases are subject to the Petroleum (Prospecting and
Mining) Act of the  Northern  Territory.  Lessees  have the  exclusive  right to
produce  petroleum from the land subject to a lease upon payment of a rental and
a royalty at the rate of 10% of the wellhead  value of the  petroleum  produced.
Rental  payments may be offset  against the royalty paid. The term of a lease is
21 years, and leases may be renewed for successive terms of 25 years each.

                  Since 1992,  there has been an ongoing  controversy  regarding
the  Aborigines  and the ownership of their  traditional  lands.  There has been
legislation aimed at resolving this  controversy.  The Company does not consider
that this issue will have a material adverse impact on MPAL's properties.

                  In Belize, Central America, the Company has interests directly
and  indirectly  through a subsidiary  in the  following PSA is which issued for
eight years but work and  expenditure  obligations  are  calculated  in two year
blocks. Application is made ninety days prior to the two year block expiration.

         (v)      Seasonality of Business.

                  Although the Company's  business is not  seasonal,  the demand
for oil and especially gas is subject to fluctuations in the Australian weather.

         (vi)     Working Capital Items.

                  See Item 7 - Liquidity and Capital  Resources for a discussion
of this information.

         (vii)    Customers.

                  Although the majority of the  Company's  producing oil and gas
properties  are located in a relatively  remote area in central  Australia  (See
Item 1 - Business and Item 2 -  Properties),  the  completion in January 1987 of
the Amadeus Basin to Darwin gas pipeline has provided access to and expanded the
potential market for the Company's gas production.

                  Natural Gas Production

                  MPAL's  principal  customer and the most likely major customer
for future gas sales is PAWA, a governmental authority of the Northern Territory
Government,  which also has substantial regulatory authority over MPAL's oil and
gas  operations.  The loss of PAWA as a customer  would have a material  adverse
effect on MPAL's business.

                  Oil Production

                  There is presently a small local market for the Mereenie crude
oil in the Alice Springs area. Most of the crude oil production is being shipped
and sold to a refinery in Adelaide.

         (ix)     Renegotiation of Profits or Termination of
                  Contracts or Subcontracts at the Election
                  of the Government.

                  Not applicable.

         (x)      Competitive Conditions in the Business.

                  The  exploration  for and production of oil and gas are highly
competitive  operations.  The  ability to exploit a  discovery  of oil or gas is
dependent upon such  considerations as the ability to finance development costs,
the  availability  of equipment,  and engineering  and  construction  delays and
difficulties.  The Company  also must compete  with major  companies  which have
substantially greater resources than the Company.

                  Furthermore,   competitive  conditions  may  be  substantially
affected  by  various  forms of  energy  legislation  which  have been or may be
proposed in Australia,  Canada, the United States and Belize; however, it is not
possible to predict the nature of any such  legislation  which may ultimately be
adopted or its effects upon the future operations of the Company.

                  At the present time, the Company's  principal income producing
operations are in Australia and for this reason,  current competitive conditions
in Australia are material to the Company's  future.  Currently,  most indigenous
crude oil is consumed within  Australia.  In addition,  imports of crude oil are
made by refiners and others to meet the overall  demand in  Australia.  The Palm
Valley Participants and the Mereenie  Participants are developing and separately
marketing  the  production  from each field.  Because of the  relatively  remote
location of the Amadeus Basin and the inherent  nature of the market for gas, it
would be impractical for each working  interest partner to attempt to market its
respective share of production from each field.

         (xii)    Environmental Regulation.

                  The  Company  is  subject  to  the   environmental   laws  and
regulations  of the  jurisdictions  in which it  carries  on its  business,  and
existing or future laws and regulations  could have a significant  impact on the
exploration for and development of natural resources by the Company. However, to
date,  the Company has not been required to spend any unusual  material  amounts
for  environmental  control  facilities.  The federal and state  governments  in
Australia strictly monitor  compliance with these laws but compliance  therewith
has not had any adverse  impact on the  Company's  operations  or its  financial
resources.

         (xiii)   Number of Persons Employed by Company.

                  At June 30,  1999,  the Company had no full time  employees in
the United States and MPAL had 33 employees in Australia.  The Company relies to
a great extent on consultants for legal, accounting and administrative services.

         (d)      Financial Information About Foreign and Domestic
                  Operations and Export Sales.

                  (1)      Financial Information Relating to Foreign and
                           Domestic Operations.

                           See Note 12 to the Consolidated Financial Statements.

                  (2)      Risks Attendant to Foreign Operations.

                           Most of the  properties  in  which  the  Company  has
interests are located outside the United States and are subject to certain risks
involved in the ownership and  development of such foreign  property  interests.
These  risks  include  but  are  not  limited  to  those  of:   nationalization;
expropriation;  confiscatory  taxation;  changes in foreign  exchange  controls;
currency  revaluations;  price  controls or  excessive  royalties;  export sales
restrictions;  limitations on the transfer of interests in exploration licenses;
and  other  laws and  regulations  which  may  adversely  affect  the  Company's
properties,  such as those providing for conservation,  proration,  curtailment,
cessation,  or other limitations of controls on the production of or exploration
for  hydrocarbons.  Thus, an investment in the Company  represents a speculation
with risks in addition  to those  inherent  in  domestic  petroleum  exploratory
ventures.

                  (3)      Data Which  are  Not  Indicative of Current or Future
                           Operations.

                           MPAL and its co-venturer  in the  Mereenie field have
been  negotiating  with PAWA and other  parties  to sell  production  out of the
field's uncommitted gas reserves.  A new gas supply contract for the uncommitted
reserves in the  Mereenie  field could  increase  revenue  from gas sales in the
future.

Crude oil (per bbl)                  A.$20.20         A.$24.55          A.$27.71

                           The average  production  cost per unit  of production
for the  following  fiscal years has been  impacted by  transportation  costs on
Mereenie oil in  Australia.  During 1999,  the cost of remedial  work on various
wells in the Mereenie field and lower production increased production costs.

Item 3.  Legal Proceedings.

Kotaneelee Gas Field

         The Company's  2.67% carried  interest in the  Kotaneelee  gas field is
held in trust by Canada Southern Petroleum Ltd. ("Canada  Southern") which has a
30%  carried  interest  in the  field.  Canada  Southern  and the  Company  (the
"Plaintiffs")  believe that the working  interest  owners in the  Kotaneelee gas
field have not  adequately  pursued the  attainment of contracts for the sale of
Kotaneelee gas; accordingly,  legal action in the United States was commenced by
Canada  Southern  in 1987  against  AlliedSignal  Inc.  and  Allied  Corporation
(collectively,  Allied Signal).  This suit was ultimately  dismissed in December
1988.


<PAGE>


         In October 1989 and in March 1990,  Canada Southern filed statements of
claim in the Court of Queens  Bench of  Alberta,  Judicial  District of Calgary,
Canada,  against the working interest  partners in the Kotaneelee gas field. The
named defendants were Amoco Canada Petroleum  Corporation,  Ltd., Dome Petroleum
Limited  (now  Amoco  Canada  Resources  Ltd.),  and  Amoco  Production  Company
(collectively  the "Amoco Dome Group"),  Columbia Gas Development of Canada Ltd.
("Columbia"), Mobil Oil Canada Ltd. ("Mobil") and Esso Resource of Canada Ltd.
("Esso") (collectively the "Defendants").

         The  Plaintiffs  claim that the Defendants  breached  either a contract
obligation  or a fiduciary  duty owed to the  Plaintiffs  to market gas from the
Kotaneelee gas field when it was possible to so do. The  Plaintiffs  assert that
marketing  the  Kotaneelee  gas was  possible  in 1984 and  that the  Defendants
deliberately  failed  to do so.  The  Company  seeks  monetary  damages  and the
forfeiture of the Kotaneelee gas field.  The  Plaintiffs  presented  evidence at
trial that the monetary damages  sustained by the Plaintiffs were  approximately
Cdn.$110 million (Company share-U.S.$5.8 million).

         In addition,  the Plaintiffs have claimed that the Plaintiff's  carried
interest  account  should be reduced  because of the negligent  operation of the
field and improper  charges to the carried  interest  account by the Defendants.
The Plaintiffs claim that when the Defendants in 1980 suspended  production from
the field's gas wells, they failed to take  precautionary  measures necessary to
protect and maintain the wells in good operating condition. The wells thereafter
deteriorated,  which caused unnecessary  expenditures to be incurred,  including
expenditures  to  redrill  one well.  In  addition,  the  Plaintiffs  claim that
expenditures made to repair and rebuild the field's  dehydration plant would not
have been necessary had the facilities been properly  constructed and maintained
by the Defendants. The expenditures,  the Plaintiffs claim, were inappropriately
charged to the field's  carried  interest  account.  The effect of an  increased
carried  interest  account is to extend the period  before  payout begins to the
carried interest account owners.

         The  Plaintiffs  claim  that  production  from the  field  should  have
commenced  in 1984.  At that  time the  field's  carried  interest  account  was
approximately  Cdn.$63 million. The Company claims that by 1993 at least Cdn.$34
million of  unnecessary  expenses  had been  wrongfully  charged to the  carried
interest  account.   The  Company's  2.6%  share  of  these  expenses  would  be
approximately  Cdn.$.9 million. The Plaintiffs further claim that, if production
had commenced in 1984, the carried  interest account would have been paid off in
approximately  two years and the  Company  would have begun to receive  revenues
from the field in 1986.  Projections  by the operator  indicate that the carried
interest  account may reach  payout  status  prior to the end of 1999.  However,
there can be no  assurances  that  payout  will  occur  within  that  timeframe,
inasmuch as there are uncertainties as to production levels, gas pricing,  field
operating  expenses,  additional  capital  expenditures  and the  impact  of the
Kotaneelee litigation.


<PAGE>


         Columbia has filed a counterclaim  against the Plaintiffs  seeking,  if
the  Plaintiffs  are  successful  in its claim for the  forfeiture of the field,
repayment  from  the  Plaintiffs  of  all  sums  Columbia  has  expended  on the
Kotaneelee lands before the Plaintiffs are entitled to their interest.

         The parties to the litigation have conducted  extensive discovery since
the filing of the claims.  The trial,  which  started on September  3, 1996,  is
still in progress. The trial was adjourned during the period December 1996-April
1997,  July-August 1997, and July-August 1998. The trial resumed on September 8,
1998  and the  Plaintiff's  case  was  completed  on  September  16,  1998.  The
Defendants  began their case on September  16, 1998 and the trial was  adjourned
for the July-August 1999 period and resumed on September 7, 1999.

Matters Ancillary to Kotaneelee Litigation

         In its 1989  statement of claim,  the  Plaintiffs  sought a declaratory
judgment regarding two issues:

         (1)      whether interest accrued on the carried interest account; and

         (2)      whether  expenditures  for  gathering  lines  and  dehydration
                  equipment are expenditures  chargeable to the carried interest
                  account or whether the Plaintiff will be assessed a processing
                  fee on gas throughput.

         With  respect  to the first  issue,  the  Plaintiffs  maintain  that no
interest should accrue on the account and the Defendants have not contested this
position.  With regard to the second  issue,  the  Plaintiffs  maintain that the
expenditures are chargeable to the carried  interest  account.  Mobil,  Esso and
Columbia have essentially  agreed to the Company's position while the Amoco Dome
Group  continues to contest this issue and claims that the remaining costs to be
recovered  at  February  28,  1999 were  Cdn.$78  million  (U.S.$52  million) as
compared to the other party's amount of Cdn.$13.5  million  (U.S.$9  million) at
such date.

         On January 22,  1996,  the  Plaintiffs  settled two claims  outstanding
against  the  Company  in the Court of Queens  Bench,  Calgary,  Alberta,  which
related to a suit brought against AlliedSignal in Florida which was dismissed on
the basis that Canada was the appropriate forum for the litigation. AlliedSignal
had sought  additional  relief  against the Company in Canada to preclude  other
types of suits by the  Company  and to recover  the costs of the  defense of the
initial action. The settlement bars AlliedSignal from making a claim against the
Plaintiffs  for any costs in  connection  with the  Kotaneelee  Litigation.  The
Plaintiffs  agreed not to bring any action  against  AlliedSignal  in connection
with the  Kotaneelee gas field.  Neither party made any monetary  payment to the
other party.



<PAGE>


         In 1991,  Anderson  Exploration Ltd.  acquired Columbia and changed its
name to Anderson Oil & Gas Inc. ("Anderson").  Anderson is now the sole operator
of the field and is a direct defendant in the Canada Court lawsuits.  Columbia's
previous  parent,  The Columbia Gas System,  Inc.,  which was  reorganized  in a
bankruptcy  proceeding in the United States, is contractually liable to Anderson
in the legal proceeding described above.

         The working  interest  owners have reported that they have been selling
Kotaneelee  gas since February 1991. The Company is uncertain as to what impact,
if any, these sales may have on the status of the litigation.

         Under  Canadian law,  certain  costs (known as "taxable  costs") of the
litigation may be assessed against the  non-prevailing  party.  Previously,  the
Company  had  reported  that  while such  costs  were not  determinable,  Canada
Southern had estimated that taxable costs,  assuming a twelve month trial, could
be approximately Cdn.$1.5 million and noted that the judge in complex and length
trials has the discretion to increase an award.  MPC has not agreed to share any
costs that might be assessed against Canada Southern,  however,  MPC's potential
share would not have exceeded U.S.$80,000.

         Effective September 1, 1998, the Alberta Rules of Court were amended to
provide  for a  material  increase  in the  costs  which may be  awarded  to the
prevailing party in matter before the Court. In addition, the trial has extended
well beyond its original time estimates  and,  therefore,  potential  assessable
costs would increase accordingly.

         The trial has been lengthy,  complicated  and costly to all parties and
the Company believes that the prevailing party or parties in the litigation will
argue for a substantial  assessment of costs against the non-prevailing party or
parties.  The Court has very broad  discretion  as to whether to award costs and
disbursements   and  as  to  the  calculation  of  the  amount  to  be  awarded.
Accordingly,  the  Company  is unable to  determine  whether,  in the event that
Canada Southern does not prevail on its claims in the litigation,  costs will be
assessed against it or in what amount.  However, since the costs incurred by the
Defendants have been  substantial,  and since the Court has broad  discretion in
the awarding of costs, an award to the Defendants potentially could be material,
if such costs were to be directly assessed against the Company.

         There is no  assurance  whatever  that Canada  Southern and the Company
will be  successful  on the merits of their claims, which have been vigorously
defended by the  Defendants.  There is also no assurance that Canada Southern or
the Company will be awarded any damages,  or that,  if damages are awarded,  the
Court will apply the  measure of damages  that Canada  Southern  and the Company
claim should be applied.



<PAGE>


         Canada  Southern has been  advancing and paying all the legal and other
expenses  of  the  Kotaneelee  litigation.  The  Company  has  not  received  an
accounting of the amounts  spent to date and  understands  that Canada  Southern
expects to recover its costs only from any judgment in favor of the  Plaintiffs.
The  Company  believes  that the  outcome of the  Kotaneelee  litigation  is not
reasonably  likely to have a material  adverse  effect on the  Company's  future
consolidated financial condition or results of operations.

Item 7.  Management's Discussion and Analysis of Financial Condition
         and Results of Operations.

(1)      Liquidity and Capital Resources - June 30, 1999

Consolidated

         At June 30, 1999, the Company on a consolidated basis had approximately
$15.5 million of cash and securities.

         A summary of the major changes in cash and cash equivalents  during the
period is as follows:

         Cash and cash equivalents at beginning of period           $12,436,000
         Cash provided by operations                                  4,993,000
         Dividends to MPAL minority shareholders                       (687,000)

                                                                    -----------
         Cash and cash equivalents at end of period                 $13,381,000
                                                                    ===========

As to the Company (unconsolidated)

         At  June  30,  1999,  Magellan  Petroleum  Corporation  ("MPC"),  on an
unconsolidated  basis, had working capital of approximately $3.6 million.  MPC's
annual operating budget is approximately  $700,000 and its current cash position
and  annual  MPAL  dividend   should  be  adequate  to  meet  its  current  cash
requirements.  During  the  fiscal  year 2000,  MPC has  budgeted  approximately
$200,000 for oil and gas  exploration  compared to the $92,000  expended  during
1999.  MPC has in the past  invested  and may in the future  invest  substantial
portions  of its  cash to  maintain  its  majority  interest  in its  subsidiary
company,  MPAL.  During fiscal 1999,  MPC purchased  113,000 shares of MPAL at a
cost of approximately $112,000.

         During  December  1998,  MPC  received a dividend from MPAL of $599,000
(after the $106,000 Australian withholding tax) which was added to MPC's working
capital.

As to MPAL

         At June 30,  1999,  MPAL  had  working  capital  of  approximately  $11
million.  MPAL has budgeted  approximately $2.5 million for specific exploration
projects in the fiscal year 2000 and  allocated  $1.3 million for  potential new
projects as compared to the $2 million  expended during fiscal 1999. The current
composition of MPAL's oil and gas reserves are such that MPAL's future  revenues
in the long term are expected to be derived from the sale of gas in Australia.



<PAGE>


         The  following  is  a  summary  of  MPAL's   required  and   contingent
commitments for exploration expenditures for the five year period ended June 30,
2004. The contingent amounts will be dependent on such factors as the results of
the current program to evaluate the exploration  permits,  drilling  results and
the Company's financial position.

                      ==========                ===========          ===========

         MPAL expects to fund its  exploration  costs through its cash flow from
Australian  operations  and any  balance  from its  A.$10  million  bank line of
credit.

         The Company has assessed  that its Year 2000  readiness is compliant at
June 30,  1999.  The Year 2000  change had no material  impact on the  Company's
internal  operations or financial results.  The Company will be dependent on its
suppliers, partners and customers to make their systems year 2000 compliant, but
this  reliance  should not have a  material  effect on the  Company's  financial
results.

(2)      Results of Operations

1999 vs. 1998

         The Company  had  consolidated  net income of $945,212  for fiscal 1999
compared  to net  income of  $1,036,513  for  fiscal  1998.  The  components  of
consolidated net income for the comparable periods were as follows:

          Oil  sales  decreased  37% in  fiscal  1999.  Oil  sales in  Australia
decreased  in 1999 to  $2,573,000  from  $4,098,000  in 1998  because  of an 18%
decrease  in oil  prices,  the 8%  Australian  foreign  exchange  rate  decrease
discussed below and a 17% decrease in the number of units  produced.  Because of
low oil prices,  it has not been economic to drill  additional wells to increase
production.  Oil unit sales (before deducting royalties) in barrels ("bbls") and
the average price per barrel sold during the periods indicated were as follows:

 Gas sales in Australia  decreased 8% in fiscal 1999.  Gas sales  decreased from
$10,485,000  in 1998 to $9,640,000 in 1999 because of the 8% Australian  foreign
exchange  rate  decrease  discussed  below.  The  volumes in billion  cubic feet

         Other production income increased 82% to $1,185,000 in 1999 compared to
$652,000 in 1998.  The primary reason for this increase was that MPAL's share of
gas pipeline  tariffs  increased to  $1,061,000  in 1999 compared to $531,000 in
1998.  In the 4th  quarter  of fiscal  1999 the amount  increased  because of an
anticipated  resolution  of a  dispute  regarding  the  producers'  share of the
tariffs.

         Interest income decreased 3% to $717,000 in 1999 from $741,000 in 1998.
Although  additional  funds were available for investment,  substantially  lower
interest rates and the 8% Australian  foreign  exchange rate decrease  discussed
below offset the increase.

                               Costs and Expenses

         Production costs increased 20% to $4,372,000 in 1999 from $3,647,000 in
1998. The increase relates to the costs at Mereenie where  substantial  remedial
work was  performed  on 8 wells and the costs  associated  with the proposed LPG
plant.  During the 4th quarter of fiscal year 1999, the loss attributable to the
LPG plant was reduced by $300,000 to $190,000.

         Salaries and employee benefits decreased 10% from $1,435,000 in 1998 to
$1,297,000 in 1999.  Compensation costs decreased in Australia together with the
8% Australian foreign exchange rate decrease discussed below.

          Depreciation,  depletion  and  amortization  increased  7% in  1999 to
$2,357,000  from  $2,205,000  in  1998.  The  increase  was  the  result  of the
additional costs from the Mereenie Central  Treatment Plant upgrade added to the
depletion  calculation  which was partially offset by the 8% Australian  foreign
exchange rate decrease discussed below.

         Exploratory and dry hole costs totaled  $2,059,000 during 1999 compared
to $3,346,000 in 1998.  The costs in 1999 related  primarily to the  Springbok-1
well offshore Western Australia which was plugged and abandoned during the first
quarter and the Belize project which was written off in the third quarter of the
fiscal year. In 1998, the Schilling-1  well and the Kittiwake-1  well which were
drilled offshore Western Australia were also abandoned. The costs (in thousands)
in fiscal 1999 and fiscal 1998 for MPC and MPAL were as follows:

         Auditing,  accounting and legal expenses  increased 6% from $480,000 in
1998 to $510,000 in 1999.  The increase in the 1999 period  relates to the legal
and tax advice sought in connection with an unsuccessful  bid to acquire certain
oil and gas properties in Australia.

         Shareholder communications increased 9% to $185,000 in 1999 compared to
$169,000 in 1998 because of increased exchange listing fees.

         Other  administrative  expenses  decreased 20% from $957,000 in 1998 to
$765,000  in 1999.  Rent and  travel  expenses  decreased  and  there  was an 8%
Australian foreign exchange rate decrease as discussed below.

                                  Income Taxes

         Income  tax  expense  decreased  from  $144,000  in 1998 to a credit of
$52,000 in 1999.  The effective  income tax rate for 1999 was -2% compared to 5%
in 1998.  The  components  of income tax  expense  between  MPC and MPAL were as
follows:

                                                =========              ========

         In 1998,  there was no 15% Australian  withholding  tax on the dividend
paid by MPAL to MPC  compared  to a  withholding  tax of  $105,000  in 1999.  In
addition, MPAL's income tax expense in 1999  (recognized during the 4th quarter)
and 1998 was lower due to the effect of permanent tax benefits under  Australian
tax law and the  utilization  of prior  year  losses not  previously  taken into
account.

                                 Exchange Effect

         The  value  of  the  Australian  dollar  relative  to the  U.S.  dollar
increased to $.6675 at June 30, 1999 compared to the value of $.6194 at June 30,
1998.  This  resulted  in  a  $1,314,000   credit  to  accumulated   translation
adjustments  for fiscal  1999.  The 8% increase  in the value of the  Australian
dollar  increased the reported asset and liability  amounts in the balance sheet
at June 30, 1999 from the June 30, 1998  amounts.  The annual  average  exchange
rate used to  translate  MPAL's  operations  in  Australia  for fiscal  1999 was
$.6281, which is a 8% decrease compared to a $.6810 rate for the comparable 1998
period.

1998 vs. 1997

         The Company had  consolidated  net income of $1,036,513 for fiscal 1998
compared  to  net  income  of  $693,987  for  fiscal  1997.  The  components  of
consolidated net income for the comparable periods were as follows:

          Oil  sales  decreased  39% in  fiscal  1998.  Oil  sales in  Australia
decreased  in 1998 to  $4,098,000  from  $6,740,000  in  1997  because  of a 11%
decrease  in oil prices,  the 13%  Australian  foreign  exchange  rate  decrease
discussed  below and a 19%  decrease in the number of units  produced.  Oil unit
sales (before deducting royalties) in barrels ("bbls") and the average price per
barrel sold during the periods indicated were as follows:

          Gas sales  in  Australia  decreased  9%  in  fiscal  1998.  Gas  sales
decreased  from  $11,552,000  in 1997 to  $10,485,000 in 1998 because of the 13%
Australian  foreign  exchange rate decrease  discussed below which was partially
offset by a 3% increase in the volume of gas sold.  The volumes in billion cubic

         Other  production  income decreased 60% to $652,000 in 1998 compared to
$1,644,000 in 1997.  The primary  reason for this decrease was that MPAL's share
of gas pipeline tariffs  decreased to $531,000 in 1998 compared to $1,498,000 in
1997. The 1998 amount  decreased  because of a dispute  regarding the producers'
share of the tariffs.

         Interest  income  decreased  10% to $741,000  in 1998 from  $822,000 in
1997.  Although  additional  funds were available for investment,  substantially
lower  interest  rates and the 13%  Australian  foreign  exchange  rate decrease
discussed below offset the increase.

         Loss on sale of assets.  During  March  1998,  MPAL  agreed to sell its
15.625%  interest in ATP 378P  Queensland,  Australia  to its  partner,  Santos,
Limited. The $636,000 difference between the carrying cost and the sale price is
included in loss on the sale of assets.

                               Costs and Expenses

         Production costs decreased 24% to $3,647,000 in 1998 from $4,811,000 in
1997.  The  decrease  relates to a decrease in costs at Mereenie and Palm Valley
and the 13% Australian foreign exchange rate decrease discussed below.

          Depreciation,  depletion  and  amortization  increased  3% in  1998 to
$2,205,000  from  $2,140,000  in  1997.  The  increase  was  the  result  of the
additional costs added to the depletion  calculation  which was partially offset
by the 13% Australian foreign exchange rate decrease discussed below.

         Exploratory and dry hole costs totaled  $3,346,000 during 1998 compared
to $6,243,000 in 1997. In 1998, the Schilling-1  and the Kittiwake-1  well which
were drilled  offshore  Western  Australia  were  abandoned.  In 1997,  the Baca
County,  Colorado project was abandoned.  In Belize,  the Gladden No. 1 well was
also plugged and  abandoned in 1997.  The costs (in  thousands) in 1998 and 1997
for MPC and MPAL are as follows:

         Bad  debts  increased  to  $239,000   during  the  1998  period.   MPAL
established a reserve for the amount due from Pegasus Gold  Australian Pty. Ltd.
because of its bankruptcy filing.

                                  Income Taxes

         Income tax expense  decreased  from  $1,442,000  in 1997 to $144,000 in
1998. The effective income tax rate for 1998 was 5% compared to 34% in 1997. The
components of income tax expense between MPC and MPAL were as follows:

         In 1998,  there was no 15% Australian  withholding  tax on the dividend
paid by MPAL to MPC. In  addition,  MPAL's  income tax expense in 1998 was lower
due to the effect of permanent tax benefits under Australian tax law.

                                 Exchange Effect

         The  value  of  the  Australian  dollar  relative  to the  U.S.  dollar
decreased to $.6194 at June 30, 1998 compared to the value of $.7538 at June 30,
1997.  This  resulted  in  a  $3,284,000   charge  to  accumulated   translation
adjustments  for fiscal 1998.  The 18%  decrease in the value of the  Australian
dollar  decreased the reported asset and liability  amounts in the balance sheet
at June 30, 1998 from the June 30, 1997  amounts.  The annual  average  exchange
rate used to  translate  MPAL's  operations  in  Australia  for fiscal  1998 was
$.6810,  which is a 13%  decrease  compared to a $.7830 rate for the  comparable
1997 period.

Item 7A. Quantitative and Qualitative Disclosure About Market Risk.

         The Company  does not have any  significant  exposure to market risk as
the only market risk  sensitive  instruments  are its  investments in marketable
securities.  At June  30,  1999,  the  carrying  value of such  investments  was
approximately $2.10 million, the fair value was $2.06 million and the face value
was $2.09 million. Since the Company expects to hold the investment to maturity,
the maturity  value should be realized.  During the year 1999,  the value of the
Australian  dollar  relative to the U.S.  dollar  increased 8% and increased the
reported asset amounts at June 30, 1999 from the June 30, 1998 amounts.

                         MAGELLAN PETROLEUM CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                  June 30, 1999

1.       Summary of significant accounting policies

         Principles of consolidation

         The accompanying consolidated financial statements include the accounts
of  Magellan  Petroleum  Corporation  ("MPC")  and its  subsidiaries,  hereafter
referred to collectively as the "Company".  All intercompany  transactions  have
been  eliminated.  At June 30,  1999  and  1998,  MPC  owned a 50.9%  and  50.7%
interest, respectively, in Magellan Petroleum Australia Limited ("MPAL"). During
fiscal 1999,  MPC increased its interest in MPAL by purchasing  additional  MPAL
shares for $112,000.

         Revenue Recognition

         The  Company  recognizes  oil and gas  revenue  from its  interests  in
producing  wells as oil and gas is produced and sold from those  wells.  Oil and
gas sold is not significantly  different from the Company's share of production.
Revenues  from  the  purchase,  sale  and  transportation  of  natural  gas  are
recognized  upon  completion  of the  sale  and  when  transported  volumes  are
delivered.

         Oil and Gas Properties

         Oil and gas properties are located in Australia, Canada, Belize and the
United States.  The Company follows the successful  efforts method of accounting
for its oil and gas  operations.  Under  this  method,  the costs of  successful
wells, development dry holes and productive leases are capitalized and amortized
on a  unit-of-production  basis  over the  life of the  related  reserves.  Cost
centers for  amortization  purposes are  determined on a  field-by-field  basis.
Estimated  future  abandonment and site  restoration  costs,  net of anticipated
salvage values,  are accrued based on units of production.  Unproved  properties
with significant  acquisition costs are periodically  assessed for impairment in
value,  with any impairment  charged to expense.  The successful  efforts method
also  imposes  limitations  on the  carrying or book value of proved oil and gas
properties  and  requires an  impairment  provision  or noncash  charge  against
earnings for any quarter in which their carrying value exceeds the  standardized
measure of  undiscounted  future net cash flows from proved oil and gas reserves
based  on  prices  received  for oil and  gas  production  as of the end of that
quarter or a subsequent  date prior to publication of financial  results for the
quarter.

                         MAGELLAN PETROLEUM CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                  June 30, 1999

1.       Summary of significant accounting policies (Cont'd)

         Exploratory   drilling   costs  are   initially   capitalized   pending
determination  of  proved  reserves  but are  charged  to  expense  if no proved
reserves  are  found.   Other  exploration  costs,   including   geological  and
geophysical expenses, leasehold expiration costs and delay rentals, are expensed
as incurred.

         Use of Estimates

         The preparation of consolidated financial statements in conformity with
generally accepted  accounting  principles requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

         Land, buildings and equipment and field equipment

         Land,  buildings and equipment and field equipment are carried at cost.
Depreciation and  amortization are provided on a straight-line  basis over their
estimated useful lives.  The estimated  useful lives are:  buildings - 40 years,
equipment and field equipment - 3 to 15 years.

         Inventories

         Inventories  consist of crude oil in  various  stages of transit to the
point of sale and are valued at the lower of cost (determined on an average cost
basis) or market.

         Foreign currency translations

         The accounts of the Company's  Australian  subsidiaries  are translated
into U.S. dollars in accordance with Statement of Financial Accounting Standards
No. 52. The translation  adjustment is included as a component of  stockholders'
equity and comprehensive income (loss), whereas gain or loss on foreign currency
transactions  is  included  in the  determination  of  income.  All  assets  and
liabilities  are  translated  at the rates in effect at the balance sheet dates.
Revenues,  expenses,  gains and losses are translated using a quarterly weighted
average exchange rate for the period.  At June 30, 1999 and 1998, the Australian
dollar was equivalent to U.S.$.6675, and $.6194, respectively.

         Recently issued accounting standards

         As of July 1,  1998,  the  Company  adopted  Statement  130,  Reporting
Comprehensive Income.  Statement 130 establishes new rules for the reporting and
display of  comprehensive  income and its components;  however,  the adoption of
this  Statement  had no  impact on the  Company's  net  income or  shareholders'
equity.  Statement  130  requires  unrealized  gains or losses on the  Company's
available-for-sale securities and foreign currency translation adjustments to be
included in other comprehensive  income. Prior to the adoption of Statement 130,
these  items  were  reported  separately  in  stockholders'  equity.  Prior year
financial  statements have been  reclassified to confirm to the  requirements of
Statement 130.

         For the year ended June 30,  1999,  the Company  adopted  SFAS No. 132,
Employers'  Disclosures about Pension and Other  Postretirement  Benefits.  This
Statement  revises  employers'  disclosures  about pension  plans,  but does not
result  in any  financial  impact.  SFAS No.  132  standardizes  the  disclosure
requirements  for  pensions  benefits  to  the  extent   practicable,   requires
additional information on changes in the benefits obligations and fair values of
plan assets that will  facilitate  financial  analysis,  and eliminates  certain
disclosures (see Note 10 of Notes to Financial Statements).

         In June 1998,  FASB  issued  SFAS No. 133,  Accounting  for  Derivative
Instruments  and Hedging  Activities  ("SFAS No. 133").  SFAS No. 133 provides a
comprehensive  and consistent  standard for the  recognition  and measurement of
derivatives and hedging activities. The statement requires all derivatives to be
recognized on the balance sheet at fair value and establishes  standards for the
recognition  of changes in such fair value.  SFAS No. 133 is  effective  for the
Company's  2001  fiscal  year.  Because  the  Company  does  not  currently  use
derivatives,  the adoption of SFAS No. 133 will not have a significant effect on
earnings or the financial condition of the Company.

         Accounting for income taxes

         The Company  follows  FASB  Statement  109,  the  liability  method  in
accounting  for  income  taxes.  Under  this  method,  deferred  tax  assets and
liabilities are determined based on differences  between the financial reporting
and tax bases of assets and  liabilities  and are measured using the enacted tax
rates and laws  that will be in effect  when the  differences  are  expected  to
reverse.

         Cash and cash equivalents

         The Company  considers all highly  liquid short term  investments  with
maturities  of  three  months  or less at the  date  of  acquisition  to be cash
equivalents.  Cash and cash  equivalents are carried at cost which  approximates
market value. The components of cash and cash equivalents are as follows:

         Earnings per share

         Earnings per common share is based upon the weighted  average number of
common and common  equivalent  shares  outstanding  during the period.  The only
reconciling  item in the  calculation  of diluted EPS is the dilutive  effect of
stock options which was computed using the treasury stock method.  The Company's
basic and diluted calculations of EPS are the same.

         Financial instruments

         The carrying value for cash and cash equivalents,  accounts receivable,
marketable  securities  and accounts  payable  approximates  fair value based on
anticipated cash flows and current market conditions.

         Segment Disclosure

         FASB  Statement No. 131 requires the  disclosure  of certain  financial
data based on an  entity's  operating  segments.  The  Company's  two  operating
segments are MPC and MPAL.  Condensed financial statements of these segments are
included in Notes 3 and 4 and additional segment data are included in Note 11.

          (a)     Australia

Mereenie

         MPAL (35%) and  Santos  (65%),  the  operator,  (together  known as the
Mereenie  Participants)  own the Mereenie  field which is located in the Amadeus
Basin of the Northern  Territory.  MPAL's share of production  from the field is
subject  to net  overriding  royalties  aggregating  3.0625%  and the  statutory
government  royalty of 10%. MPAL's share of the Mereenie field proved  developed
oil reserves was approximately 730,000 barrels at June 30, 1999.


<PAGE>


2.       Oil and gas properties (Cont'd)

         The field was producing about 1,700 (MPAL share - 595) barrels of crude
oil per day ("bpd") at June 30, 1999. During 1999, MPAL's share of oil sales was
236,000  barrels and 3.4 billion  cubic feet ("bcf") of gas sold from 41 oil and
gas wells. The oil is transported by means of a 167 mile eight-inch oil pipeline
from the field to the Brewer Estate industrial park near Alice Springs.  Most of
the oil is then  shipped  south  approximately  950  miles by rail and road to a
refinery in the Adelaide area. The cost of transporting  the oil to the refinery
is being borne by the producers.  The Mereenie  Participants  are also providing
Mereenie gas in the Northern Territory to the Power and Water Authority ("PAWA")
and Gasgo  Pty.  Ltd.,  a company  it wholly  owns,  for use in Darwin and other
Northern Territory centers. See "Gas Supply Contracts".

         During 1999, the Mereenie  Participants  had been  negotiating  for the
sale of Liquid  Petroleum  Gas from the field to a purchaser but the project was
terminated after it was determined that it was uneconomic.

Palm Valley

         MPAL has a 50.8% interest in and is the operator of the Palm Valley gas
field which is located in the Northern  Territory.  Santos,  the operator of the
Mereenie field, owns a 48% interest in Palm Valley.  Ten wells have been drilled
in the field,  five of which are currently  connected to the gas treatment plant
and are flowed at maximum  deliverability  levels to meet the Alice  Springs and
Darwin supply  contracts  with PAWA. See "Gas Supply  Contracts".  During fiscal
1999,   MPAL's   share  of  gas  sales  was  3.7  bcf.   In  order  to  increase
deliverability,  field  compression  began  in  November  1996  with  two 400 HP
compressors.  A third 800 HP compressor was installed  during fiscal 1999.  MPAL
has recommended  that four additional wells be drilled at Palm Valley to improve
the field's production  capacity.  Under the gas supply agreement with PAWA, the
costs  of  these  wells  are   reimbursed   by  PAWA  and,   consequently,   the
recommendation is under review by PAWA's consultants.

         MPAL's  share of Palm  Valley  production  revenues is subject to a 10%
statutory government royalty and net overriding royalties aggregating 4.2548%.

Gas Supply Contracts

         In 1983,  the Palm  Valley  Participants  commenced  the sale of gas to
Alice Springs under a 1981 agreement.  In 1985, the Palm Valley Participants and
Mereenie  Participants  signed agreements for the sale of gas to PAWA for use in
PAWA's Darwin generating station and at a number of other generating stations in
the  Northern  Territory.  The gas is being  delivered  via the 922 mile Amadeus
Basin to Darwin gas pipeline which was built by an Australian consortium.  Since
1985, there have been several additional contracts for the sale of Mereenie gas.
The  following  is a  summary  of MPAL's  interest  in the Palm  Valley  and the
Mereenie gas supply contracts:

</TABLE>

         Under the 1985  contracts,  there is a difference in price between Palm
Valley  gas and most of the  Mereenie  gas for the first 20 years of the 25 year
contracts  which  takes  into  account  the  additional  cost  to  the  pipeline
consortium  to build a spur line to the Mereenie  field and increase the size of
the pipeline from Palm Valley to Mataranka.

         In consideration for the Palm Valley  Participants  forgoing 20% of the
Amadeus Basin to Darwin gas supply  contract during the first 20 contract years,
Mereenie  Participants  made  a  payment  to the  Palm  Valley  Participants  to
partially  compensate the Palm Valley  Participants  for the reduced net present
value of the future gas sales  revenues which were postponed from contract years
1 to 20 to contract  years 21 to 26. The  agreement  also provides that when the
Mereenie  Participants sell any additional gas from the Mereenie field, the Palm
Valley  Participants are entitled,  as additional  consideration,  to 35% of the
revenues  from the first 38 bcf (MPAL share - 19.5 bcf) of gas sold. At June 30,
1999, the balance of the Mereenie  Participants  gas subject to this entitlement
was 9.7 bcf (MPAL share - 4.8 bcf).

         At June 30,  1999,  the Company had  accrued  $849,000  for future site
restoration  costs for the Mereenie and Palm Valley  fields.  The balance of the
estimated  liability is  $3,246,000  at June 30, 1999 which will be accrued over
the remaining life of the related reserves based on units of production.

Dingo Gas Field

         MPAL has a 34.3%  interest  in the Dingo gas field  which is held under
Retention  License 2 and is subject  to  renewal  in 2003.  The Dingo gas field,
which  is  located  in  the  Amadeus  Basin  in  the  Northern  Territory,   has
approximately 25 bcf of presently proved and recoverable  reserves based on four
delineation  wells. Dingo 2 and Dingo 3 wells are estimated to have the capacity
of producing a combined rate of 5 million  cubic feet  ("mmcf") per day.  MPAL's
share of  potential  production  from  these  permit  areas is  subject to a 10%
statutory government royalty and overriding royalties aggregating 2.5043%.

Ngalia Basin

         MPAL had a 40%  interest  in permit  EP-15 in the  Ngalia  basin in the
Northern Territory which expired during May 1999. During July 1998, the Newhaven
well was plugged and  abandoned.  MPAL's  share of the drilling  costs  incurred
through June 30, 1998 were  included in  exploratory  and dry hole costs for the
1998 fiscal year. The costs to drill the well subsequent to June 30, 1998 in the
amount of $316,000  are  included in  exploratory  and dry hole costs for fiscal
1999.

Northern Surat Basin

         During  fiscal  1998,  MPAL  sold  its  15.625%  interest  in ATP  378P
Queensland,  Australia to its partner,  Santos. The $636,000  difference between
the carrying  cost and the sale price was included in loss on the sale of assets
for the 1998 fiscal year.

Surat Basin

         During the 1998 fiscal  year,  MPAL earned a 17% interest in Block D of
ATP 244P in  Queensland  by  completing a pilot  seismic  reprocessing  program.
During the 1999 fiscal year, MPAL abandoned its interest in the permit.

         During  fiscal  1998,  MPAL  earned  a 15%  interest  in  ATP  626P  in
Queensland. During fiscal 1999, MPAL relinquished its interest in the permit.

Timor Sea

         During April 1998,  MPAL acquired a 5% interest in  Exploration  Permit
WA-199-P in the  Bonaparte  Basin in the Timor Sea offshore  Western  Australia.
MPAL  earned its  interest  in the permit by funding 10% of the cost of drilling
the Kittiwake-1  well which was a dry hole.  MPAL's cost of the well was written
off in the fourth quarter of fiscal 1998 and was included in exploratory and dry
hole costs.  MPAL relinquished its interest in the permit during the 1999 fiscal
year.

Browse Basin

         During the 1999 fiscal year,  MPAL  was  granted  a 17.5%  interest  in
exploration permits WA-281-P, WA-282-P and WA-283-P in the Browse Basin offshore
Western Australia. During the 1999 fiscal year, MPAL spent approximately $67,000
toward the Year 1 work obligations. MPAL's share of the work obligations for the
three permits is as follows:

Carnarvon Basin

         MPAL earned a 15% interest in  exploration  permits  TP/12 and EP398 in
the Carnarvon  Basin  offshore  Western  Australia by funding 30% of the cost of
drilling the Springbok-1  well. The  Springbok-1  well was plugged and abandoned
during August 1998.  MPAL's cost of drilling the well was written off during the
first quarter of fiscal 1999.

         During April 1999, MPAL was awarded permit  WA-291-P,  offshore Western
Australia in the Carnarvon  Basin. The minimum  expenditure  obligations for the
first three year period totals $347,000. The discretionary  commitment for years
4-6 totals approximately $4.8 million.

Maryborough Basin

         MPAL holds a 98%  interest in  exploration  permit ATP 613P,  a 670,000
acre block, in the Maryborough Basin in Queensland, Australia.

Cooper Basin

         During April 1999,  MPAL (50%) and its partner Beach  Petroleum NL were
successful in bidding for two  exploration  blocks in South  Australia's  Cooper
Basin.  The formal  grant of the  permit is  pending.  MPAL's  share of the work
obligations during the five year period of the permit are as follows:

          (b)     Canada

          The Company has a 2.67% carried  interest in the  Kotaneelee gas field
in the Yukon Territory which has been on production  since February 1991.  There
are two wells  capable  of  production  in the  field  which is part of a permit
covering 31,885 gross acres. For financial statement purposes in fiscal 1987 and
1988,  the  Company  wrote down its  Canada  cost  center,  which  included  the
Kotaneelee  field to a nominal value because of the  uncertainty  as to the date
when sales of Kotaneelee gas might begin and the  immateriality  of the carrying
value of the  investment.  Although the field is now producing,  the Company has
not yet  classified  its share of the  Kotaneelee gas reserves as proved because
the gas field is still the subject of  litigation.  The Company will  reclassify
the reserves at the Kotaneelee  field as proved when there is greater  assurance
as to the timing and assumptions  regarding the  investment.  Projections by the
operator  of the field,  indicate  that the carried  interest  account may reach
payout status prior to December 1999.

          (c)     United States

Baca County, Colorado

         MPC (10%) and MPAL  (90%)  participated  in an  exploration  program in
Colorado.  During 1995, MPAL commenced a three well drilling program.  All three
wells  were dry  holes.  During  fiscal  1995 and 1996,  the  Company  wrote off
$809,000 and $1,691,000 in costs, respectively.  During fiscal 1997, the Company
drilled a fourth well which was a dry hole and all of the remaining costs of the
project,  which totaled  $3,008,000,  were written off. During fiscal 1999, MPAL
spent approximately $16,000 on the project and it is allowing most of the leases
to expire.

Tapia Canyon, California

         Effective December 1, 1997,  MPC acquired a 20% interest in a heavy oil
recovery  project  in  Tapia  Canyon,   California.   Because  the  Company  was
dissatisfied  with the  program to develop the field  reserves,  the Company has
sold its  interest for its  approximate  cost of $101,000  effective  August 31,
1999.

Stephens County, Texas

         During  fiscal  1999,  MPC  participated  (20%) in the  drilling of the
Puckett No. 1 well which is presently  suspended.  There are  indications of oil
and additional work will be performed  during  September 1999.  During late June
1999,  MPC also  participated  (21.4%) in the  drilling  of the Smith No. 1 well
which also has  indications  of oil.  MPC's  capitalized  costs at June 30, 1999
totaled $71,000.

          (d)     Belize

Southern Offshore Block PSA

         During  March 1998,  MPC (3%),  MPAL (20%) and the other joint  venture
participants  entered into a new Production  Sharing  Agreement ("PSA") with the
Government of Belize.  The new Southern  Offshore Block PSA ("SOB PSA") combines
most of the blocks previously  included in the Gladden PSA and the Block 13 PSA,
and totals approximately  893,000 acres. The work obligations of the new PSA are
as follows: Year 1 - $100,000, Year 2 - $300,000, Year 3 - $3,000,000 and Year 4
- -  $150,000.  The  participants  in the PSA have been  seeking  partners  in the
venture. The first year obligations have been completed and the participants are
negotiating with the Government of Belize to reduce the Year 2 obligations.

Gladden Basin PSA/Block 13 PSA

         During  1997,  the Gladden No. 1 well was plugged and abandoned and the
Company's  cost of the well was written off.  During March 1998,  this block was
consolidated into the SOB PSA.

         MPC and MPAL were also  participants in a Production  Sharing Agreement
("Block 13 PSA") offshore Belize  adjoining the western and southern  boundaries
of the Gladden PSA. The Block 13 PSA covered approximately 788,000 acres. During
March 1998, this block was consolidated into the SOB PSA.

5.       Capital and stock options

         The Company's Certificate of Incorporation  provides that any matter to
be voted upon must be approved not only by a majority of the shares  voted,  but
also by a majority of the  stockholders  casting  votes  present in person or by
proxy and entitled to vote thereon.

         On October 5, 1989,  the Company  adopted a Stock Option Plan  covering
one million shares of the Company's  common stock. The plan provides for options
to be  granted  at a price of not less than fair  value on the date of grant and
for a term of not greater  than ten years.  On  December  3, 1997,  the Board of
Directors  approved a new stock option plan for an additional one million shares
which was approved at the 1998 Annual Meeting of Stockholders.

         At June 30, 1999, all of the stock options  outstanding were vested and
exercisable.  Options to purchase  146,000 shares expire on October 20, 2003 and
options to purchase  50,000 (which were  repriced from $2.75 to $1.57,  the fair
value on the date of  repricing)  shares  expire on September  25, 2001.  During
fiscal 1999,  options to purchase  175,000 shares of common stock were exercised
in a  cashless  exchange  which  resulted  in the  issuance  of  75,731  shares.
Following is a summary of option transactions for the three years ended June 30,
1999:

Options outstanding              Number of shares          Exercise Prices ($)
July 1, 1996                           516,250                 .75 - 1.0625

                                      --------
  Granted                              146,000                     1.57
  Exercised                           (225,000)                   .8125
                                      ---------
June 30, 1999                          196,000                     1.57
                                      ========
                                                        ($1.57 weighted average)
Options reserved for future grants   1,000,000

         The Company has elected to follow  Accounting  Principles Board Opinion
No. 25,  "Accounting  for Stock  Issued to  Employees"  (APB No. 25) and related
interpretations in accounting for its stock options because the alternative fair
value  accounting  provided under FASB Statement No. 123,  "Accounting for Stock
Based  Compensation,"  requires  use of option  valuation  models  that were not
developed  for use in  valuing  stock  options.  Under APB No. 25,  because  the
exercise  price of the Company's  stock  options  equals the market price of the
underlying stock on the date of grant, no compensation expense is recognized.

5.       Capital and stock options (Cont'd)

         Upon exercise of options, the excess of the proceeds over the par value
of the shares  issued is credited to capital in excess of par value.  No charges
have been made against  income in accounting  for options  during the three year
period ended June 30, 1999.

         Pro forma  information  regarding  net income and earnings per share is
required  by  Statement  123,  and has been  determined  as if the  Company  had
accounted for its stock  options under the fair value method of that  Statement.
The fair value for these  options  was  estimated  at the date of grant  using a
Black-Scholes option pricing model.

         Option  valuation  models  require  the  input  of  highly   subjective
assumptions including the expected stock price volatility.  The assumptions used
in the 1997 valuation model were: risk free interest rate - 6.55%, expected life
- - 5 years,  expected  volatility - .579,  expected dividend - 0. The assumptions
used in the 1999 valuation model were: risk free interest rate - 4.45%, expected
life - 5 years,  expected  volatility - 1.0,  expected dividend - 0. Because the
Company's stock options have characteristics  significantly different from those
of traded options,  and because changes in the subjective input  assumptions can
materially affect the fair value estimate, in management's opinion, the existing
models do not necessarily provide a reliable single measure of the fair value of
its stock options.

         For the purpose of pro forma  disclosures,  the estimated fair value of
the  stock  options  is  expensed  in the year of grant  since the  options  are
immediately exercisable. The Company's pro forma information follows:

                                                          Amount       Per Share

not be construed as being exact and verifiable  quantities.  The reserves may or

future net cash flows.  Moreover,  estimates of proved  reserves may increase or
decrease  as a result of future  operations  and  economic  conditions,  and any
production from these properties may commence earlier or later than anticipated.

Discounted future net cash flows:

         The following is the standardized measure of discounted (at 10%) future
net cash flows (in thousands) relating to proved oil and gas reserves during the
three years ended June 30, 1999.  Australia was the only cost center with proved
reserves. At June 30, 1999, approximately 49.1% (49.3% for 1998 and 1997) of the
reserves and the respective discounted future net cash flows are attributable to
minority interests.

Reserves - Natural Gas

         Future net cash flows from net proved gas  reserves in  Australia  were
based on MPAL's share of reserves in the Palm Valley and  Mereenie  fields which
have been limited to the quantities of gas committed to specific contracts.

Reserves and Costs - Oil

         At June 30,  1999,  future  net cash  flows  from  the net  proved  oil
reserves  in  Australia  were  calculated  by  the  Company.   Estimated  future
production and development  costs were based on current costs and rates for each
of the three years ended at June 30,  1999.  All of the crude oil  reserves  are
developed  reserves.  Undeveloped  proved reserves have not been estimated since
there are only tentative plans to drill additional wells.

Income taxes

         Future Australian income tax expense  applicable to the future net cash
flows  has  been  reduced  by the tax  effect  of  approximately  A.$13,081,000,
A.$9,995,000 and A.$9,236,000 in unrecouped  capital  expenditures at 1999, 1998
and 1997,  respectively.  The tax rate in computing Australian future income tax
expense was 36%.

          For financial  statements  purposes in fiscal 1987 and 1988, MPC wrote
down its Canada cost center which included the Kotaneelee gas field to a nominal
value because of the  uncertainty  as to the date when sales of  Kotaneelee  gas
might  begin and the  immateriality  of the  carrying  value of the  investment.
Although  the field is now  producing,  the Company has not yet  classified  its
share of the  Kotaneelee  gas reserves as proved  because the gas field is still
the subject of  litigation.  The Company  will  reclassify  the  reserves at the
Kotaneelee field as proved when there is greater  assurance as to the timing and
assumptions of the investment.

ARTICLE II - PRELIMINARY

2.1      GAS RESERVES

         The Purchaser accepts and the Producer warrants that natural gas having
         an  equivalent  energy  value  (based  on Gross  Heating  Value)  of 40
         petajoules  (approximately  1,000 million cubic metres) is in existence
         within the  fractures  in the Gas  Field.  However,  should  subsequent
         investigations  demonstrate  the existence of additional  quantities of
         Specification  Natural Gas which can be delivered  without the need for
         additional  capital  investment by the Producers,  this Agreement shall
         apply to such  additional  quantities up to an equivalent  energy value
         (based on Gross Heating Value) of 15 petajoules.

2.2      ROUTINE PRODUCTION AND INSTALLATION OF GAS DELIVERY SYSTEM

         As soon as  practicable  after the execution of this  Agreement and the
         granting of the  Petroleum  Lease and the  receipt of the  notification
         from the  Purchaser  provided for under Clause 2.4 hereof the Producers
         will at their own expense  proceed with due diligence to render the Gas
         Field  suitable  for routine  production  and install the Gas  Delivery
         System  with  sufficient  supply  provisions  to enable the  continuous
         supply  of  Specification  Natural  Gas to the  Purchaser  at the Field
         Delivery Station pursuant to Clause 2.3.

2.3      CONTINUITY OF SUPPLY

         The Producers,  except by reasons of force majeure,  and their right to
         suspend deliveries of gas in accordance with Clause 8.4 hereof, warrant
         a sufficient supply of Specification  Natural Gas to the Field Delivery
         Station   to   maintain   continuity   of  supply  to  the   Purchaser.
         Notwithstanding  this  warranty,  it is  recognised  that the Producers
         must, on occasion,  shut in  production  facilities in the Gas Field to
         perform reservoir tests and evaluations.  Provided such testing periods
         do not exceed the following  durations and frequencies,  no damages due
         to loss of  Specification  Natural Gas supply  shall  become due to the
         Purchaser under this provision.

         Years following Initial
         Delivery into Trunk               Permissible duration
         Pipeline                          of Shut in                  Frequency
         -----------------------           --------------------        ---------

            1 and 2                              120 hours             Quarterly
            3 and 4 and 5                         96 hours             Quarterly
            6 and 7 and 8                         72 hours             Quarterly
            9 until contract                      48 hours             Annually
            expiration

         The time chosen for field  testing shall be arranged with the Purchaser
         to correspond with periods of low electrical  demand. In addition,  the
         Producers  shall be allowed  additional shut in periods for unscheduled
         events not  exceeding a total of  forty-eight  (48) hours in each year.
         Should loss of field production  availability exceed the limits defined
         above,  or such other  limits as may  otherwise  be agreed  between the
         Purchaser  and the  Producers,  and any such  loss of field  production
         availability  in excess of the agreed limits results in an interruption
         of supply to Alice Springs Power Station,  the Producers shall,  unless
         otherwise agreed between the Purchaser and Producers, become liable for
         fuel supply  damages for the excess  duration.  Such  damages  shall be
         computed  on the  differential  costs of fuel for  generation  at Alice
         Springs   caused  by  the  need,   arising   from  the  excess   supply
         interruption,  to  substitute  distillate  for natural gas in the Power
         Station.  Distillate  used in such  circumstances  shall be costed on a
         L.I.F.O.  basis from the Purchaser's inventory at Alice Springs, or the
         actual  cost of  acquisition  at the power  station,  whichever  is the
         greater,  and  Specification  Natural  Gas shall  also be costed at its
         delivered  cost to the Purchaser at the Alice Springs Power Station and
         any  claims  under  this  provision  may be  subject  to  audit  by the
         Producers.


<PAGE>

2.4      GAS TRANSMISSION

         The   Purchaser   shall   complete    necessary    arrangements    with
         Owner/Operators  of the  Trunk  Pipeline  for  the  transmission  at no
         expense to the Producers of all quantities of Specification Natural Gas
         sold  under this  Agreement  from the Field  Delivery  Station to Alice
         Springs.  The Purchaser shall notify the Producer when it has completed
         the necessary  arrangements with  Owner/Operators of the Trunk Pipeline
         at least nine (9) months prior to anticipated commissioning date of the
         Trunk  Pipeline and the  Purchaser  shall have no right to terminate or
         withdraw  from this  agreement if it does not complete  such  necessary
         arrangements.

2.5      NO ENTITLEMENT TO PIPELINE LICENCE

         Nothing in this  agreement  is to be  construed  either  directly or by
         implication, to entitle or to prohibit any or all or any combination of
         the parties to this agreement,  to an entitlement to a pipeline licence
         under the Energy  Pipelines  Act in  respect  of an  "energy  pipeline"
         outside the boundaries of the Lease area.

2.6      OBLIGATION TO TRUNK PIPELINE OPERATOR

         Force  majeure  and  the  Producers'   right  to  suspend  delivery  in
         accordance  with Clause 8.4 hereof  excepted,  if the Producers fail to
         offer for delivery,  quantities of  Specification  Natural Gas required
         under the minimum take and or pay  obligation  of Schedule II Column A,
         and if, as a result,  the Purchaser  becomes liable for payments to the
         Trunk  Pipeline  Operator,  at  the  end of any  Contract  Year,  which
         payments   are  in  excess  of   Specification   Natural  Gas  actually
         transported  up to that time,  any excess  payments  for  Specification
         Natural Gas not actually  transported up to the minimum take and/or pay
         quantities of Schedule II Column A shall become the  obligations of the
         Producers.

ARTICLE III - PURCHASE AND SALE OF GAS

3.1      QUANTITY OF GAS

         Each of the Producers in the  percentages of the separate  ownership of
         each as set out in Recital (d) hereof  agree to sell the  Specification
         Natural Gas having an aggregate equivalent energy value (based on Gross
         Heating  Value) of not less  than 40  petajoules  (approximately  1,000
         million cubic metres) and such additional  Specification Natural Gas as
         can  be  made  available  without  the  need  for  additional   capital
         investment by the Producers up to an equivalent  energy value (based on
         Gross Heating Value) of 15 petajoules. Prior to the sale of Natural Gas
         or natural  gas liquids  from the Palm  Valley  field to other than the
         Purchaser under the terms of this agreement, the Producers will warrant
         the supply at the Field Delivery Station of  Specification  Natural Gas
         having an aggregate  energy  equivalent  value (based on Gross  Heating
         Value) of 55 petajoules over the term of this  Agreement.  Furthermore,
         as provided in Clause 5.3 hereof,  the Purchaser  agrees to buy on take
         and/or  pay  basis,  Specification  Natural  Gas  having  an  aggregate
         equivalent energy value (based on Gross Heating Value) of not less than
         32.2  petajoules  (approximately  805 million cubic metres)  during the
         twenty (20) years  following  initial  delivery into the Field Delivery
         Station.

3.2      SCHEDULE OF QUANTITIES

         Each of the Producers  shall deliver at the flange  connecting  the Gas
         Delivery  System to the Trunk  Pipeline and the Purchaser  shall buy at

         3.1 in accordance with SCHEDULES II and III attached.


<PAGE>

ARTICLE IV - TERM OF AGREEMENT

4.1      TERM OF AGREEMENT

         This  Agreement  shall become  effective upon the date of execution and
         shall  continue in effect for at least  twenty (20) years from the date
         of  initial   delivery  into  the  Field  Delivery   Station  or  until
         Specification  Natural Gas having an aggregate  equivalent energy value
         (based on Gross Heating  Value) of 40 petajoules  (approximately  1,000
         million cubic metres) and such additional  quantities of  Specification
         Natural Gas as may be available  pursuant to Clauses 2.1 and 3.1 hereof
         shall have been delivered whichever later occurs but in any event until
         not later than twenty-five (25) years from the date of initial delivery
         at the Field Delivery Station.

ARTICLE V - PRICE

5.1      BASE PRICE

         The  agreed  base  price  for  Specification  Natural  Gas  under  this
         Agreement is $1.12 per gigajoule  (based on Gross Heating Value) at 1st
         October 1981.  It is further  agreed that the price will be adjusted at
         each Review Date as defined in Clause  1.10 in  accordance  with Clause
         5.2 and the Price Review Formula specified in SCHEDULE III attached.

5.2      PRICE REVIEW

         The price per gigajoule  (based on Gross  Heating  Value) to be paid by
         the  Purchaser  to  each  of  the  Producers  for  each   gigajoule  of
         Specification  Natural Gas under this Agreement shall be fixed for each
         Quarter  in  accordance  with the Price  Review  Formula  specified  in
         SCHEDULE III attached.


<PAGE>

5.3      TAKE AND/OR PAY PROVISIONS

         During a maximum  period of twenty (20) years after the date upon which
         the Producers commence to deliver  Specification  Natural Gas hereunder
         or 1st December  1984  whichever  first occurs the  Purchaser  shall be
         bound to take  and/or  pay for  Specification  Natural  Gas  having  an
         aggregate  equivalent  energy value (based on Gross  Heating  Value) of
         32.2 petajoules  (approximately 805 million cubic metres) in accordance
         with  SCHEDULES  II and III attached  PROVIDED  ALWAYS that any of this
         said gas paid for but not actually  taken by the Purchaser may be taken
         by the Purchaser  without  further  payment in any subsequent  Contract
         Year, (without counting as part of the Specification  Natural Gas which
         the Purchaser is otherwise bound to take in such  subsequent  year) and
         any such  adjustments  may be credited  forward within the term of this
         Agreement. If deliveries of Specification Natural Gas commence on other
         than the 1st July, the amount of gas to be taken and/or paid for in the
         first  Contract  Year shall be calculated  pro rata and the  difference
         between  that  figure and the figure in Column A of Schedule II will be
         applied  to reduce  the  total  take  and/or  pay  requirement  of 32.2
         petajoules.  Such  adjustments  shall be  performed  at the end of each
         Contract  Year and payments  billed in the first month of the following
         Contract Year.

5.4      CONSUMER PRICE INDEX

         In the event that the  Consumer  Price  Index as defined in Clause 1.12
         shall be  discontinued  or  modified  the  parties  shall  request  the
         Commonwealth  Statistician  to provide  figures or indices  which shall
         give an  equivalent  comparison  to that  contemplated  by the Consumer
         Price Index. If the parties are unable to obtain from the  Commonwealth
         Statistician figures or indices which give an equivalent  comparison to
         that  provided  by the said  index  and are  unable  to  agree  between
         themselves  as to such figures or indices  either the  Producers or the
         Purchaser may request the President for the time being of the Economics
         Society of Australia  and New Zealand or his nominee to provide at each
         review date figures or indices which give an  equivalent  comparison to
         that  contemplated  by the  Consumer  Price  Index and such  figures or
         indices  shall then for the purposes of this  Agreement be deemed to be
         the Consumer Price Index.


<PAGE>

5.5      PRICE ADJUSTMENT

         If at any time during the term of the Agreement additional royalties or
         severance or sales tax or taxes of a similar  nature or  equivalent  in
         effect shall be validly imposed or increased by any lawful Governmental
         Authority  of the  Northern  Territory  on  the  gas  delivered  to the
         Purchaser  pursuant  to  this  Agreement,  or on or in  respect  of the
         production  thereof  or on  the  sale  thereof,  so  that  each  of the
         Producers  shall be required to pay such new or additional or increased
         rate of taxes either directly or indirectly, the price per gigajoule to
         be paid by the Purchaser to each of the Producers shall, subject to the
         condition  hereinafter  set forth, be increased to include any such new
         or  additional  or  increased  rate  of tax  PROVIDED  HOWEVER  that in
         computing  any such new or  additional  or increased  rate of tax there
         shall not be included increases in income taxes.

5.6      NEW ADDITIONAL LEVY ROYALTY TAX

         If at any time during the term of this Agreement any new, additional or
         increased levy,  royalty,  severance tax or sales tax shall be lawfully
         imposed by any Government other than the Northern Territory  Government
         or its agencies on the  Producers in respect of  Specification  Natural
         Gas sold  hereunder  the payment of which shall  required the Producers
         thereafter to produce and sell gas hereunder on a continuing basis at a
         loss,  the  Producers  may  thereupon  give a notice  to the  Purchaser
         containing  the  calculations   which  result  in  such  loss  and  the
         additional  price per  gigajoule  which it would be  necessary  for the
         Purchaser to pay to enable the Producers to produce and sell gas to the
         Purchaser  without  loss.  If within  ninety (90) days of the giving of
         such notice the  Purchaser  fails to enter into an  undertaking  to the
         Producers to pay such additional price per gigajoule for  Specification
         Natural  Gas  thereafter  sold  and  delivered  to  the  Purchaser  the
         Producers  may at any time within ninety (90) days  thereafter  rescind
         this Agreement.  If the Purchaser  disputes any of the  calculations of
         the Producers including the additional price per gigajoule contained in
         the first notice from the Producers the Purchaser may refer the matters
         in dispute to  arbitration  pursuant to Article  XII.  Any right of the
         Producers to rescind  shall be  postponed  until  twenty-one  (21) days
         after the final determination of the arbitration. If during such period
         the Purchaser  shall  undertake to the Producers to pay the  additional
         amount per gigajoule found necessary to enable the Producers to produce
         and sell gas to the Purchaser  without loss the Producers shall have no
         right to rescind consequent thereupon.


<PAGE>

         Profit or loss for the  purpose of this  clause  shall bring to account
         all capital  costs and all expenses and  outgoings  incurred or paid by
         the  Producers  subsequent  to the  date of this  Agreement  and in the
         course of the performance thereof and shall be determined in accordance
         with generally accepted accounting standards.

ARTICLE VI - ADJUSTMENT OF GAS TO SPECIFICATION

6.1      RIGHTS OF PURCHASER

         Should the natural gas tendered for delivery hereunder fail to meet all
         of the  specifications  set forth in SCHEDULE I attached the  Purchaser
         shall have the  right,  after  written  notification  to the  Producers
         showing  evidence  of the gas  specification  deficiency,  to refuse to
         accept further  deliveries of such gas until such failure is rectified,
         and the Producer shall become liable for fuel supply  damages  incurred
         as defined in Clause 2.4 and if such failure  continues for a period of
         not  less  than  seven  (7)  days  or  such  further  period  as may be
         reasonably necessary in the circumstances  bearing in mind the cause of
         such failure after the  Purchaser  shall have notified the Producers in
         writing  thereof,  the  Purchaser at its option may accept such gas and
         install,  operate and maintain  such  facilities  as may be required to
         cause such gas to meet such  specifications.  The Purchaser  shall have
         the right to recover from each of the Producers in the  percentages set
         out in Recital (d) hereof all costs incidental thereto,  including fuel
         supply damages,  depreciation,  overhead and costs of capital by way of
         deduction from sums payable for gas delivered  hereunder.  In the event
         that the gas supplied fails to achieve a minimum Gross Heating Value of
         36MJ/m3,  the Producer shall  compensate the Purchaser for the pipeline
         tariff costs associated with the movement of the additional  volumes of
         gas  through  the  Trunk  Pipeline   required  to  achieve  the  energy
         equivalence  of gas rated at 36MJ/m3 over the period of delivery of the
         specification breach.


<PAGE>

6.2      REMOVAL OF CONSTITUENTS

         So long as the Specification  Natural Gas remains within specification,
         the Producers  may, prior to delivery  thereof,  submit such gas to any
         process  the  Producers  desire  for the  removal  of  constituents  or
         elements  therein  other than for the removal of methane  (except where
         methane  removal is an unavoidable  consequence of the removal of other
         constituents).  Such separate  constituents or elements will remain the
         property of the Producers in the  percentages of separate  ownership of
         each as set out in Recital (d) hereof.

ARTICLE VII - MEASUREMENT

7.1      UNITS OF MEASUREMENT

         The  unit of  measurement  for gas  delivered  hereunder  shall  be one
         gigajoule  (109  joules)  based  on  Gross  Heating  Value.  Volumetric
         measurement for computation  purposes shall be in units of cubic metres
         (volumetric  measurements  made in other  units  will be  converted  as
         appropriate).

7.2      MEASUREMENT FACTORS

         Unless  otherwise  specifically  set out,  the volume of gas  delivered
         hereunder  shall  be  computed  in  accordance  with  the  instructions
         contained  in the Gas  Measurement  Committee  Report  Number  3 of the
         American Gas Association, dated April 1955, together with all presently
         existing  supplements,  amendments  and  appendices to the said Report.
         Such  instructions  to be converted where necessary for compliance with
         Australian Standard AS1000-1979 "The International System of Units (SI)
         and Its Application",  the Commonwealth "Weights and Measures (National
         Standards) Act 1960-1966" and Regulations thereunder and the Australian
         Gas Association  publication  "Metric Units and Conversion  Factors For
         Use  In  The  Australian  Gas  Industry".   Factors   required  in  the
         computations  to be made in accordance with the said Report No. 3 shall
         be  determined  in the  following  manner  using  equipment  installed,
         maintained and operated by the Producers:


<PAGE>

         (a)      The  temperature  of gas  flowing  through  the meter shall be
                  continuously  measured  by a  recording  thermometer  so as to
                  record properly the temperature of the flowing gas.

         (b)      The  pressure  of gas  at  the  meter  shall  be  continuously
                  measured  by a  recording  pressure  device  so as  to  record
                  properly the pressure of the gas at the meter.

         (c)      A composite sample of gas shall be collected monthly (over the
                  Billing  Period)  by means of a gas  sampler  at the  point of
                  measurement of the gas at the Field Delivery Station.

         (d)      The  Gross  Heating  Value  of the gas  shall be  measured  by
                  passing  the  composite  sample  referred to in (c) through an
                  approved calorimeter.

         (e)      The  gravity  of the gas  shall be  measured  by  passing  the
                  composite  sample  referred  to in  (c)  through  an  approved
                  gravitometer.

         (f)      The correction for deviation of the gas from Boyle's Law shall
                  be made in accordance  with the said Report No. 3 on a monthly
                  basis.

7.3      BAROMETRIC PRESSURE

         The  average  atmospheric  pressure  at the  point for the  purpose  of
         calculation   hereunder  shall  be  accurately  measured  by  a  method
         acceptable  to both  parties  at the Field  Delivery  Station or if the
         parties are unable to agree upon an acceptable  method then by a method
         nominated by the Bureau of Meteorology.


<PAGE>

7.4      METERS

         All gas  delivered at the Field  Delivery  Station shall be measured by
         means of meters of standard type selected by the Producers and approved
         by all parties to the Agreement  (such approval not to be  unreasonably
         withheld)  which shall be  installed,  operated and  maintained  by the
         Producers  together with all appurtenant  field equipment  necessary to
         measure accurately and record the volumes of gas delivered. Such meters
         shall at all reasonable times be subject to check,  test and inspection
         by  the  Purchaser  of its  agent  but  the  reading,  calibrating  and
         adjusting  thereof and the changing of charts shall be done only by the
         Producers  being  witnessed by the Purchaser or its agent should it see
         fit.  The  records  from such  measuring  equipment  shall  remain  the
         property of the  Producers,  but they shall submit to the  Purchaser or
         its agent, as may from time to time be reasonably requested,  copies of
         the records and charts  together  with the  calculations  therefrom for
         inspection and verification.  All such charts and other similar records
         (or microfilm copies thereof) shall be preserved by the Producers for a
         period of at least seven (7) years.

7.5      CHECK METERS

         The  Purchaser or its agent at its option and expense,  may install and
         operate adjacent to the Producers' meters check meters of the same type
         installed and operated by the Producers to check the Producers' meters,
         but measurements of gas shall be by the Producers'  meters only, except
         in cases herein  specifically  provided to the  contrary.  Check meters
         shall be subject at all reasonable times to inspections or examinations
         by the Producers,  but the reading,  calibrating and adjusting  thereof
         and the changing of charts  shall be done only by the  Purchaser or its
         agent being witnessed by the Producers should they see fit.


<PAGE>

7.6      TEST AND CORRECTION OF ERRORS

         The accuracy of the Producers measuring equipment (including where used
         but not limited to orifice meters,  temperature and pressure recorders,
         calorimeter,  and  gravitometer)  shall be  verified,  at  intervals no
         longer than 33 days by the Producers and, if requested, in the presence
         of the  Purchaser  or its  agent.  If any  party at any time  desires a
         special test of any measuring  equipment,  it will promptly  notify the
         other  parties and the parties will then  co-operate to secure a prompt
         calibration  test.  If, upon test any error in  measuring  equipment is
         found to affect  volumes  being  measured by not more than two percent,
         previous  recording  of such  equipment  shall be  considered  as being
         correct in measuring  deliveries  of gas; but such  equipment  shall be
         adjusted  at once to record  accurately.  If,  upon test,  any error in
         measuring  equipment is found to affect  volumes being measured by more
         than  two  percent,  previous  recordings  of such  equipment  shall be
         corrected to zero error for any period  during which the error is known
         definitely  or agreed to have  existed,  but in case such period is not
         known  definitely or agreed upon, such correction shall be for a period
         extending  over  one-half  of the time  elapsed  since the date of last
         test,  not  exceeding a correction  period of sixteen  (16) days.  Such
         equipment shall be adjusted at once to record  accurately.  If, for any
         reason,  any measuring  equipment is out of service or out of repair so
         that the amount of gas delivered cannot be ascertained or computed from
         the reading thereof, the amount of gas delivered during the period such
         equipment is out of service or out of repair  shall be  estimated  upon
         the basis of the best data available,  using the first of the following
         methods which is feasible:

         (a)      By  using  the registration ofany check meter  or  meters,  if
                  installed and accurately registering.

         (b)      By using the wellhead meters.

         (c)      By estimating the quantity of gas delivered by comparison with
                  gas  deliveries   during   preceding   periods  under  similar
                  conditions when the equipment was registering accurately.


<PAGE>

7.7      SEPARATE OWNERSHIP

         All gas measured by meters and delivered to the  Purchaser  pursuant to
         this Agreement shall be and be deemed to be separately owned by each of
         the Producers in the percentages set out in Recital (d) hereof.

ARTICLE VII - BILLING AND PAYMENT

         Purchaser  the right to pay the amount so due to the  Producers  within
         such seven (7) day period.

8.5      DISPUTED MONTHLY STATEMENTS

         In the  event of  disputes  arising  from  differences  in  measurement
         between the Producers'  meters and the Purchaser's or its agent's check
         meters,  the Producer shall waive the suspending and termination rights
         contained in Clause 8.4,  provided the Purchaser  makes payments within
         the  required  dates,  the  amounts  due  according  to the check meter
         quantities.  Monies  withheld,  and  subsequently  found to be payable,
         shall accrue the  interest  penalty of Clause 8.4, and shall be due and

         washouts,  arrests and  restraints  of  governments  and people,  civil
         disturbances,  explosions,  temporary  failure of gas supply because of
         breakages or accidents to machinery or lines of pipe, the necessity for
         making  repairs  to or  alterations  of  lines  of pipe  or  production
         facilities  beyond  that  required  for  normal  maintenance,   hydrate
         obstructions in wells lines of pipe or production facilities, any other
         unusual event reasonably  unforeseeable  causing interruption of supply
         from a well, and any other event or  circumstances  whether of the kind
         herein mentioned,  or otherwise,  not within the reasonable control and
         without the fault or negligence of the party  claiming  suspension  and
         which by the exercise of due diligence  such party is unable to prevent
         or  overcome.  It is  understood  and  agreed  that the  settlement  of
         strikes,  lockouts  and other  labour  difficulties  shall be  entirely
         within the discretion of the party having the difficulty,  and that the
         above  requirements  that any force  majeure shall be remedied with all
         reasonable  despatch  shall not  require the  settlement  of strikes or
         lockouts by acceding  to the  demands of the  opposing  party when such
         course  is  inadvisable  in the  discretion  of the  party  having  the
         difficulty.


<PAGE>

11.2     TERMINATION FOR PROLONGED FORCE MAJEURE

         If the  inability of either the Producer or the  Purchaser to carry out

         one (1) year the other  party may by thirty (30) days notice in writing
         given  at any  time  within  a  period  of six  (6)  months  after  the
         expiration of such year terminate this Agreement.  Any such termination
         shall be without  prejudice to any of the rights of the parties accrued
         prior to the date of such termination.

11.3     TERMINATION FOLLOWING UNDUE DELAY

         If for any reason beyond the control of the Purchaser,  it is unable to
         accept  delivery of the gas at Alice  Springs by the 1st December  1984
         then the  remaining  rights and  obligations  of the  Producers and the
         Purchaser  under this  Agreement  shall be at an end provided  that the
         Purchaser  reimburses the Producers for sums expended in fulfillment of
         their  obligations  under  this  Agreement  since  notification  of the
         anticipated  commissioning date of the Trunk Pipeline as required under
         Clause 2.4.  Any such  claims may be subject to audit by the  Purchaser
         and shall  apply  only to field  facility  improvements  and  additions
         specific to this Agreement.

ARTICLE XII - ARBITRATION

12.1     ARBITRATION

         Any  controversy  with respect to provisions  of this  Agreement in any
         case where  arbitration  is expressly  required under the provisions of
         this Agreement and in any other case if the Producers and the Purchaser
         agree,  shall be submitted to arbitration in Darwin or elsewhere as the
         parties  agree upon and the  following  principles  shall apply to such
         arbitration.


<PAGE>

         Upon  written  demand of either  the  Producers  or the  Purchaser  the
         parties shall meet and attempt to appoint a single  arbitrator.  If the
         parties are unable to agree on a single  arbitrator  then upon  written
         demand of either the  Producers  or the  Purchaser  and within ten (10)
         days of such demand the Producers and the Purchaser  shall each name an
         arbitrator and the two  arbitrators so named shall promptly  thereafter
         choose a third.  If either the Producer or the Purchaser  shall fail to
         name an  arbitrator  within  ten (10) days from such  demand,  then the
         second  arbitrator  shall be  appointed by the  President  for the time
         being of the Northern  Territory Law Society  Incorporated.  If the two
         arbitrators  shall fail within ten (10) days from their  appointment to
         agree  upon  and  appoint  the  third  arbitrator,  then  upon  written
         application  by  either  the  Producers  or the  Purchaser  such  third
         arbitrator  shall be appointed by the  President  for the time being of
         the Northern  Territory  Law Society  Incorporated.  The  arbitrator or
         arbitrators  selected to act hereunder  shall be qualified by education
         and training to pass judgement upon the particular question in dispute.
         The  single  arbitrator  or the  arbitrators  so chosen  shall  proceed
         immediately to hear and determine the question or questions in dispute.
         The decision of the single  arbitrator shall be made within  forty-five
         (45) days after his appointment, subject to any reasonable delay due to

<PAGE>

            (B) In work not chargeable or recoupable from C-M-O:

                (a) H-S  shall  commence in 1959 a program of exploration on the
            properties  or on the  optioned  acreage  which  shall  include  the
            drilling of a minimum of five  exploratory  wells,  irrespective  of
            cost, to at least a depth to test the known producing  horizons,  or
            igneous or other impenetrable formations, or a depth of 12,000 feet,
            whichever  is the  least,  of which at least one such well  shall be
            drilled  into the Pre Cambrian and one such well shall be located on
            the Western  block of the  properties,  consisting  of Permits  Nos.
            1006,  1007,  1132, 1133 and 1135. The first such  exploratory  well
            shall be located on the North Petitot structure and shall be drilled
            during the first drilling season and one well may be on the optioned
            acreage  but such well shall not be in lieu of the well  required to
            be drilled on the North Petitot structure.

                (b) In the event the  total  cost  of  the  exploratory  program
            described in (a) above should be less than $3,000,000,  then H-S are
            obligated to  spend the  difference  between  such  total  cost  and
            $3,000,000,  in exploration  and development  work on the properties
            and costs incidental or ancillary thereto.

                (c) The work  and  expenditures  described  in (a) and (b) above
            shall be completed  within five years from the date of the execution
            of this Agreement.

                (d) H-S will be obligated to reconvey the properties to C-M-O in
            the event they should fail to meet the obligations described in this
            paragraph  (B).  Such  reconveyance  shall  not  serve in any way to
            constitute partial or liquidated damages or to cancel any obligation
            undertaken by H-S under the terms of this Agreement.

            (C) Subsequent to the completion of both  (A)  and  (B)  above,  H-S
       shall permit C-M-O to enjoy  the  following  preferential  position  with
       respect to further  work done  on the  properties so long as  the work is
       performed prior to the time when any  particular or potential  oil or gas
       field is producing into a trunk pipe line, or, in the case of oil,  prior
       to the time oil moves to  market  in  quantities  that  permit  C-M-O  to
       finance its  share  of  further reasonable development pursuant to normal
       commercial banking arrangements.

                (1) Should H-S drill,  deepen  or  complete  a discovery well in
            accordance  with  the  provisions  of  Clause  N  of  the  Operating
            Procedure, in the cost of which  C-M-O  does  not  participate,  the
            rights of H-S to recoup therefrom under the terms of Clause N of the
            Operating Procedure  shall be  limited  to 300%;  that  is,  H-S may
            recoup from C-M-O's interest in such discovery well three times what
            would have been C-M-O's cost of participating in the said well.

                (2) Should H-S  drill,  deepen  or  complete  a  delineation  or
            development well  in accordance with  the provisions of  Clause N of
            the Operating Procedure,  in  the  cost  of  which  C-M-O  does  not
            participate,  the rights of H-S  to recoup therefrom under the terms
            of Clause N of the Operating Procedure  shall  be limited  to  105%;
            that is, H-S may recoup from C-M-O's interest in such delineation or
            development  well 100%  of what  would  have  been  C-M-O's  cost of
            participating in the said well plus 5%.


<PAGE>

            (D) H-S will assure the earliest feasible development and  marketing
       of oil and/or gas found on the properties.


                                   ARTICLE IV

      4.1 H-S shall have an  exclusive  option to buy from C-M-O,  for the price
and during the period hereinafter  stated, an undivided one-half interest in and
to the South one-half of Permits Numbers 1137 and 2301 comprising  approximately
31,966 acres, subject to the payment of 50% of the royalty described in Schedule
"A".  If,  as and when the  option  is  exercised,  the  optioned  acreage  will
thereafter  become  subject to this  Agreement  as a part of the  properties  as
defined. No amounts paid, in connection with the option as hereinafter provided,
shall be chargeable to or recoupable from C-M-O.

      4.2 The prices  at  which  and  periods  within  which  the  option may be
exercised are as follows:

            Before August 1, 1960, $400. per net acre acquirable;
            Before August 1, 1961, $600. per net acre acquirable;
            Before August 1, 1962, $800. per net acre acquirable;
            Before August 1, 1963, $1,000. per net acre acquirable.

      4.3 Payment shall be made upon  exercise of the option in accordance  with
the then  existing  law or  regulations  governing  oil and gas  permits  in the
Northwest Territories.  In the event that modification of the law or regulations
subsequent to the exercise of the option permits greater acreage  acquirement by
the permittees within the boundary of the optioned acreage then H-S may elect to
purchase a 50% interest in such  additional  acquirable  acreage and  additional
payment shall promptly be made  accordingly  determined by the price  pertaining
when the original option was exercised.

      4.4 Once payment has been made for  acquirable oil and/or gas rights under
any surface  acre and if other oil or gas rights are  acquirable  under the same
surface acre,  no  additional  payment shall be required to be made to C-M-O for
such other rights under such surface acre.

      4.5 Prior to the exercise of the option or its expiration  C-M-O will give
H-S thirty  (30)  days'  prior  written  notice of any well to be drilled on the
optioned acreage. H-S may participate 50% with C-M-O in the cost of drilling any
such well or wells on the optioned  acreage.  Failure to  participate,  however,
will serve to terminate  the option unless within thirty (30) days H-S agrees to
drill and does  thereafter  diligently  commence and drill a well thereon to the
known producing horizons or to igneous or other impenetrable  formations or to a
depth of 12,000 feet, whichever is the least.

      4.6 Prior to the  exercise of the option or its  expiration,  H-S may have
access to the area  under  option  and any  information  in  C-M-O's  possession
pertaining  thereto.  H-S may, upon prior written notice,  commence and drill an
exploratory  test well on the option  area at the sole cost and  expense of H-S,
none of which shall be chargeable to or recoupable from C-M-O.


<PAGE>

      4.7 Any well drilled under the  provisions  of Clauses 4.5  or  4.6  above
shall,  after its  completion,  be operated by the then operator of the optioned
acreage.

      4.8 Prior to the expiration of the option described in Article IV, neither
C-M-O nor H-S shall make  application  for oil and/or gas leases and/or licenses
under any permit  which  includes  any part of the  optioned  acreage  except by
mutual agreement, provided that, if during this period, any rules or regulations
governing  oil and gas in the Northwest  Territories  shall require or render it
advantageous  to apply for oil and/or gas leases  and/or  licenses on any of the
optioned  acreage,  then C-M-O and H-S shall meet  promptly  for the  purpose of
agreeing  upon such  application.  Consent  by H-S to the areas to be covered by
such  application  with  respect to any permit  which  includes  any part of the
optioned acreage shall not be unreasonably withheld.

      4.9 Any  exploratory  well  drilled by H-S under this  Article IV shall be
considered  one of the wells  required to be drilled  under  Article III and the
cost of any well drilled by H-S whether  exploratory or not, and the cost of any
well in which H-S participates on the optioned lands shall be considered part of
the expenditures required to be made under Article 3.1(B) (b).

      4.10 Participation in a well or any work  done on the optioned lands shall
not be deemed an exercise of the option by H-S.


                                    ARTICLE V

      5.1 At any time after a period of five (5) years  following  the execution
of this  Agreement,  C-M-O shall have the right to call for a division of all or
any of the areas which have gone to lease or license and which are jointly owned
by H-S and C-M-O and the  termination  of this  Agreement  to the extent that it
affects the areas to be subdivided.  The subdivision shall in no case affect the
obligation of H-S to assure the earliest feasible  marketing of oil or gas found
on the areas  jointly owned by H-S and C-M-O,  including  those which may become
subdivided.  The  procedure  for such  division  of said  area or areas  and the
termination of such agreement shall be as follows:

            C-M-O shall advise H-S in writing of its desire.

            Upon  receipt of this  notice  there  shall ensue a period of thirty
      (30) days within  which the parties  shall  endeavour by agreement to work
      out a division of the area or areas.

            If by the  expiration  of the said thirty (30) days no agreement has
      been reached,  C-M-O may within fifteen (15) days  thereafter  prepare and
      present  to H-S a division  into two parts of all areas to be divided  and
      other assets jointly owned in connection  therewith  under this Agreement.
      Such plan of  division  shall be in a  checkerboard  pattern  in which the
      units shall be a maximum size calculated to avoid forcible  unitization if
      possible  and a  minimum  of one  section  except  in the  case  of  lands
      producing  oil the maximum  shall be a maximum  size  calculated  to avoid
      forcible unitization if possible and a minimum of one-quarter section. H-S
      shall  have a period of thirty  (30) days  from  receipt  of the  proposed
      division  to elect  which of the two parts it desires to  receive.  If H-S
      does not make its  election  within the said thirty (30) days by notice in
      writing to C-M-O, the latter shall, within ten (10) days thereafter, elect
      which of the two parts it desires and so notify H-S.


<PAGE>

      5.2 At all times mentioned in this Article existing  contracts between the
parties shall remain in full force and effect and normal  operations  thereunder
shall  continue.  Thirty  (30) days after the final  election  is made by either
party in accordance with the above established procedure, all existing contracts
shall  terminate  with respect to the divided  properties  except as provided in
this Article.  All joint  operations in respect of the divided  properties shall
then cease and all  obligations  except the  liquidation of current  accounts of
either party to the other and  obligations  to third  parties shall be at an end
except as  provided in this  Article but during such final  thirty (80) days and
thereafter the parties will  individually  and together take whatever  action is
necessary  to  conserve  the area or areas and assets  jointly  owned by H-S and
C-M-O and to expedite final  transfer of titles and  liquidation of any accounts
and other matters pending as of the date of the termination.


                                   ARTICLE VI

      6.1 C-M-O shall promptly deliver to Home,  C-M-O's files or copies thereof
relating to the areas covered by this  Agreement,  retaining  copies thereof for
C-M-O's own use.  C-M-O shall give to Home  original or duplicate  copies of all
data  obtained by C-M-O or available to C-M-O with respect to the geology of the
areas covered by this Agreement and all other  information  which C-M-O may have
on hand or is  presently  entitled to acquire with  respect to  exploration  and
development of the areas covered by this Agreement.


                                   ARTICLE VII

INCORPORATION OF OPERATING PROCEDURE

      7.1 The  parties  agree that the  provisions  contained  in the  Operating

Where there is any conflict  between the  provisions  of this  Agreement and the

      to the  exploratory  and  development  work on the  lands;  the same to be
      furnished promptly upon completion of each such log, report, map and other
      data. Final reports shall be furnished upon the completion of each job.

            (b) The right to receive progress reports and maps from time to time
      or  immediately  upon  request.  Such reports  shall  include,  but not be
      limited  to, all facts and data  obtained  on a  drilling  well on a daily
      basis  and  the  progress,   location  and  data  obtained  by  any  other
      exploratory  operation,  including  seismic  parties,  surface  geological
      parties and core hole programs on a weekly basis.

            (c) Access to the said lands and the wells  thereon and the right at
      all times to inspect and observe the operations  being  conducted  thereon
      and therein.

            (d) The  right to  examine  the  books and  records  of the  Manager
      Operator  relating to all wells  drilled on the said lands and of sales of
      production.

            (e) Upon  request  made to  the  Manager  Operator  therefor,  to be
      furnished with copies of driller's  reports of wells drilled upon the said
      lands,  samples of cores and cuttings  taken  therefrom  and copies of all
      seismograms obtained upon the properties.

      G.2  Each  Joint  Operator   hereto  shall  treat   geological  and  other
exploratory  data  obtained in  connection  with the said lands as  confidential
information and will reveal no part of it to any third person, except with prior
written approval of the other Joint  Operators;  provided that this clause shall
not  prevent  disclosure  to  the  Government  of  information  required  by the
Government  in order to  establish  credit  for work  requirements,  or  prevent
disclosure  of  information  relating to the geology and reserves  data of known
producing  structures  to  the  extent  such  disclosures  may  be  required  in
connection  with financing by any Joint Operator,  or prevent  disclosure of any
information  to any  experts in order that such  Joint  Operator  may obtain the
opinions of such experts, or disclosure of information  relating to its reserves
relating to known  producing  structures  in a report to its  shareholders;  and
provided  further that  information  obtained from the wells  themselves  may be
disclosed  at the  discretion  of any Joint  Operator,  and that  purchasers  or
prospective  purchasers  of  gas  produced  from  the  said  lands  may,  at the
discretion  of any Joint  Operator,  for use in  connection  with  purchases  or
prospective purchases, be given all information,  whether obtained from wells or
otherwise,  of a kind that is reasonably or  customarily  given to purchasers or
prospective  purchasers of gas in like  circumstances.  Appropriate  precautions
will be taken by each Joint  Operator  to  prevent  inadvertent  disclosures  of
confidential information.

                                    CLAUSE J

ADVANCES

      J.1 The Manager Operator at its election from time to time may require any
Joint Operator to advance its proportionate share of authorized  expenditures by
furnishing such Joint Operator with an estimate of such expenditures required to
cover  operations for a period not in excess of sixty (60) days.  Within fifteen
(15)  days  after  receipt  of such  estimate  or within  ten (10)  days  before
commencement of the period covered by the estimate, whichever is the later, such
Joint Operator shall pay its proportionate part thereof.

      The  accounts  between the Joint  Operators in respect of any such advance
shall be adjusted at the end of each calendar  month in  accordance  with actual
expenditures.  Any amount not paid within the time  hereinbefore  limited  shall
bear interest at the rate of Six (6%) percent per annum.

      J.2 In the event that any Joint  Operator  fails to advance  such money as
required or make any other  payment  required  under this  Agreement,  the other
Joint Operators  participating in the operation concerned shall, upon request by

sum, or upon the Manager Operator  otherwise  recovering all or any part of such
sum, the Manager Operator shall immediately pay the amount received or recovered
to the Joint  Operators  making the  advancement  in like  proportions  and such
amount  shall be applied  first in reduction of interest and second in reduction
of capital. Provided,  however, that the members of C-M-O shall not be obligated
in respect of any expenditures to be incurred in respect of the program referred
to in Article III or the payments referred to in Article IV.

                                    CLAUSE K

LIEN

      K.1 The Manager Operator shall have a lien on the participating  equity of
each other Joint  Operator to secure payment of such Joint  Operator's  share of
all costs and expenses hereunder,  but such lien shall not attach to any portion
of  such  Joint  Operator's  share  of  production  at  any  time  prior  to the
enforcement of the same by the Manager Operator as hereinafter provided.


<PAGE>

      K.2 In the event  that any Joint  Operator  shall fail to pay its share of
any costs or expenses hereunder (and such default shall continue for thirty (30)
days after the Manager Operator shall have served written notice upon such Joint
Operator  specifying  such default and  requiring  the same to be remedied)  the
Manager  Operator may enforce such lien by taking  possession of all or any part
of the participating  equity of such Joint Operator and the Manager Operator may
sell and dispose of all or any part of such participating equity either in whole
or in separate  parcels at public  auction or by private tender at such time and
on such  terms as it shall  appoint,  having  first  given  notice to such Joint
Operator of the time and place of such sale, and the Manager  Operator is hereby
constituted  irrevocably  the attorney of such Joint Operator for the purpose of
making any such sale and executing such deeds and agreements in the name of such
Joint  Operator as may be necessary  to carry out the same.  The proceeds of any
such sale shall be first applied by the Manager Operator in payment of any costs
or  expenses  to be paid by such  Joint  Operator  and not  paid by it,  and any
balance  remaining  shall be paid to such Joint  Operator  after  deducting  the
reasonable costs of such sale. Any such sale shall be a perpetual bar in law and
equity  against such Joint  Operator and any person  claiming all or any part of
the property sold, by, from, through or under such Joint Operator.

      K.3 If any Joint Operator advances any money under the preceding clause in
respect of the  default of another  Joint  Operator  it shall have the same lien
rights in respect thereto as has the Manager Operator under this clause.

                                    CLAUSE L

DIVISION OF PRODUCTION

      L.1  Each  Joint  Operator  shall  own  its  participating  equity  in the
petroleum  substances  produced hereunder exclusive of any quantity thereof that
may be  delivered  in kind as  royalty  or  production  which may be used by the
Manager  Operator  in  developing  and  producing  operations  hereunder  and in
preparing  and  treating   production  for  marketing  purposes  and  production
unavoidably  lost.  Each Joint Operator  shall,  upon payment of or securing the
payment of any royalty with respect thereto, be entitled to take delivery of its
share of production at the point of production.  Each Joint Operator electing to
take  delivery of its  participating  equity in the petroleum  substances  shall
provide  at its own risk and  expense  adequate  facilities  for  receiving  its
production and shall bear any additional  expense to which the Manager  Operator
may be subject in delivering such production separately.  In the event any Joint
Operator fails to make arrangements to take delivery of its participating equity
in the petroleum substances the Manager Operator may sell the same upon the same
terms and  conditions  that it is selling its share of production and such Joint
Operator  shall be entitled to receive from the Manager  Operator not later than
the last day of the month  following such sale,  the net proceeds  received from
the sale of its  participating  equity in the petroleum  substances so sold. Any
market  available to a Joint Operator shall be shared by it with the other Joint
Operators to the intent and purpose that no Joint Operator shall be obligated to
store its participating  equity in production except to the proportionate extent
that the production  owned by the other Joint Operators is so stored for lack of
market.

OBLIGATORY OPERATIONS

      M.1 Upon the completion of the program provided for in Article III of this
Agreement,  each Joint  Operator  shall be obligated,  provided that the Manager
Operator  has made a bona fide but  unsuccessful  attempt  to obtain a waiver of
such  obligations,  to join in the renewal of any document of title and to pay a
share  equivalent  to its  participating  equity in that part of the said  lands
concerned of any rental and of the cost of any operation, including the drilling
of any well,  necessary  to  maintain  all or any part of the said lands in good
standing except the drilling obligations contained in any document of title when
the person  entitled to enforce the  performance  thereof is not  enforcing  the
same,  unless  such Joint  Operator  has  surrendered  or disposed of all of its
participating  equity in that part of the said  lands to which  such  obligation
applies at least thirty (30) days prior to the date on which such rental becomes
payable or on which such  operation  must be commenced in order to maintain such
part of the said  lands in good  standing.  Provided  that  C-M-O  shall  not be
obligated to participate in any obligatory well while it enjoys the preferential
rights  granted to it by Article 3.1 (C) but if it does not so  participate  the
applicable penalty under the said Article shall apply.

INDEPENDENT OPERATIONS

      N.1 Except as hereinbefore provided in Clause M hereof and Article III, no
Joint  Operator  shall be  required  to  participate  in the  cost of  drilling,
deepening, or reworking any well hereunder.

      N.2 Upon  completion  of the  program  provided  for in Article  III,  and
provided  no well is then being  drilled or  deepened  on the said lands for the
joint account, and provided no drilling or deepening operation on the said lands
has then been approved in any budget, the following provisions shall apply:

            (a) Should any Joint  Operator  desire to deepen or re-work any well
      which is incapable of producing petroleum  substances in paying quantities
      or to drill any new well, such Joint Operator shall notify the other Joint
      Operators in writing of its intention to perform the proposed operation at
      its own cost and risk. Such notice (hereinafter called "the first notice")
      shall contain information as to the location,  depth and estimated cost of
      the  operation.  In such event each Joint Operator shall be deemed to be a
      participant  in such  operation  unless it has given written notice to the
      other Joint  Operators  within thirty (30) days after receipt by it of the
      first notice,  of its intention not to  participate;  PROVIDED that if the
      operation  is the  deepening  of a well on which  the  drilling  rig to be
      utilized in such operation is then located, the time herein-before limited
      for giving written notice of intention not to participate shall be reduced
      to three (3) days exclusive of Sundays and statutory holidays, and any rig
      time  for  such  three  (3) day  period  shall  be paid  for by the  Joint
      Operators participating in the operation.


<PAGE>

            (b) The Joint Operator giving first notice shall,  together with the
      Joint Operators  participating,  be entitled to have the Manager  Operator
      commence  such  operation  within  sixty (60) days from the receipt by the
      other Joint  Operators of the first notice and  thereafter  prosecute  the
      operation  to  completion  at the sole cost and risk of the  participating
      Joint Operators in the  proportions  that their  respective  participating
      equities  in  the  spacing  unit   concerned   are  of  the  sum  of  such
      participating equities.

            (c) If the Joint Operators  participating in such operation commence
      the  same  within  the said  period  of sixty  (60)  days and  carry it on
      diligently and continuously to the depth proposed in the first notice

                 (i) if the  operation is the drilling of an  exploratory  well,
            each non-participating  Joint Operator shall forthwith assign to the
            participating   Joint  Operators  in  the  proportions   that  their
            respective   participating   equities   are  of  the   sum  of  such
            participating  equities,  all of  its  participating  equity  in all
            formations in:

                    A. six (6) Northwest Territory sections of the said lands if
               such well is drilled to a depth of more than six thousand (6,000)
               feet and provided  commercial  production  has not been  obtained
               above the depth of six thousand (6,000) feet, and

                    B. four (4) Northwest  Territory  sections of the said lands
               in the case of any other  well,  such  sections  to  include  the
               section on which such well is located  and the other  sections to
               be  selected  by the  participating  Joint  Operators  from those
               sections  laterally or diagonally  adjoining the section on which
               such well is located.

                 (ii) if the operation is a deepening or reworking  operation or
            the drilling of a development  well,  each  non-participating  Joint
            Operator  shall  have the  right,  until  the  elapse of a period of
            thirty (30) days after the participating Joint Operators have served
            on each of the  non-participating  Joint Operators written notice of
            the results of all tests  carried out on the well  concerned  (or in
            the case of a dry hole, written notice to that effect) and have made
            available to such  nonparticipating  Joint Operators all information
            concerning such well which is in the possession of the participating
            Joint Operators,  to pay to the participating Joint Operators in the
            proportions that their respective  participating equities are of the
            sum of such participating  equities,  a sum equal to three (3) times
            the  amount  it would  have  been  called  upon to pay had all Joint
            Operators being entitled to participate  originally  participated in
            the operation, and upon such payment being made, such Joint Operator
            shall  participate  in such  well and the  production  therefrom  ab
            initio to the extent that it would have been entitled to participate
            had all Joint Operators entitled to participate so participated, and
            in the  event  that it  does  not  pay  such  sum  within  the  time
            hereinbefore   limited,   such  Joint   Operator  shall  assign  its
            participating  equity in such well, in the spacing unit on which the
            same is located and in the surface  location,  to the  participating
            Joint   Operators   in  the   proportions   that  their   respective
            participating   equities  are  of  the  sum  of  such  participating
            equities, in which case the Joint Operators receiving the assignment
            shall have the right to produce the well concerned and to market the
            production of petroleum substances therefrom and the Joint Operators
            making the  assignment  shall not be  entitled  to any share of such
            production.


<PAGE>

      N.3 Notwithstanding  anything hereinbefore  contained,  if the lands to be
assigned  under this clause contain any other well then capable of production of
petroleum  substances,  such well and any zone or formation,  whichever the case
may be, underlying the spacing unit of such other well and from which it is then
capable of obtaining production shall be excluded from the lands to be assigned.

                                    CLAUSE O

SELECTION OF LEASES

      O.1 The Joint  Operators shall meet to determine the lands to be contained
in an  application  for  petroleum  and natural  gas leases.  The meeting may be
called by any Joint  Operator on the same notice as is provided in Clause D. All
decisions  relating to any such  application  and the  selection  of lands to be
included  therein shall be made by mutual  agreement and failing such  agreement
shall be made by the Joint Operators owning in the aggregate more than Sixty-six
and  two-thirds (66 2/3%) percent of the  participating  equities in such permit
provided that in making such selection leases of sections must be chosen so that
any Joint  Operator  who is  entitled to any section or sections by virtue of an
independent operation may obtain such section or sections.

                                    CLAUSE P

SURRENDER

      Upon  completion of the program  provided for in Article III the following
provisions shall apply:

      P.1 Any Joint  Operator may,  from time to time and at any time,  provided
that the Crown must or will accept the same,  surrender  all of its  interest in
all or any part of the said lands except that no such surrender shall be made:

            (a) within  thirty (30) days before the accrual of the rental or any
      other  obligation,  excepting  any  drilling  obligation  contained in any
      document  of title when the person  entitled  to enforce  the  performance
      thereof  is not  enforcing  the same,  in respect to that part of the said
      lands to be surrendered,

            (b) respecting an area of less than a spacing unit,

            (c) until the Joint  Operator  desiring  to  surrender  (hereinafter
      called "the  offeror")  shall notify in writing the other Joint  Operators
      (hereinafter  called  "the  recipients")  of the  interest  it  desires to
      surrender.  The  recipients  shall  have the right for a period of fifteen
      (15) days after the receipt of such notice to advise the offeror by notice
      in writing  that it will accept an  assignment  of such  interest.  In the
      event any  recipient  does not notify  within the time herein  limited the
      offeror that it will accept an assignment of such interest, such recipient
      shall  join in the  surrender  of  such  part of the  said  lands.  If any
      recipient  agrees  to  accept  such  assignment,  such  interest  shall be
      assigned to such  recipient.  If more than one recipient  agrees to accept
      such  assignment such interest shall be assigned to such recipients in the
      proportions that their respective  participating interests bear to the sum
      of such participating interests.

      Q.1 No Joint Operator shall dispose of any interest  hereunder  unless the
person  receiving the same agrees with the other Joint  Operators to be bound by
all of the terms and provisions of this Agreement.  If such disposition  imposes
greater obligations or expenses on the Manager Operator or other Joint Operators
then  such  person  shall  agree to pay all  costs and  expenses  in  connection
therewith.

      Joint  Operator to such  assignment  and such consent  cannot be obtained,
      such  interest  shall be held in trust by the Joint  Operator  required to
      make the assignment for the Joint Operators entitled to receive the same.

                        (Unit and Joint Lease Operations)


                              I. GENERAL PROVISIONS

1.    DEFINITIONS

      subject area covered by the agreement to which this "Accounting Procedure"
      is attached.

      The term  "Operator"  as herein used shall be  construed to mean the party
      designated  to conduct the  development  and operation of the subject area
      for the joint account.

      The term  "Non-Operator" as herein used shall be construed to mean any one
      or more of the non-operating parties.

      The  term  "rentals"  shall,  in  addition  to its  ordinary  meaning,  be
      construed  to  include  delay  rentals,  renewal  fees and  generally  all
      periodical payments of monies required to be made in order to maintain the
      rights of the parties in and to the joint property in force and effect.

2.    STATEMENTS AND BILLINGS

      The  Operator  shall bill  Non-Operator  on or before the last day of each
      month for its  proportionate  share of costs and  expenditures  during the
      preceding month. Such bills will be accompanied by statements,  reflecting
      the total cost and charges as set forth under sub-paragraph A below:

      A.    Statement in detail of all charges and credits to the joint account.

      B.    Statement  of  all  charges  and  credits  to  the  joint   account,
            summarized by appropriate  classifications  indicative of the nature
            thereof.

      C.    Statements, as follows:

            (1)  Detailed   statement   of    material   ordinarily   considered
                 controllable by operators of oil and gas properties;


<PAGE>

            (2)  Statement of all other charges and credits to the joint account
                 summarized  by  appropriate  classifications  indicative of the
                 nature thereof; and

            (3)  Statement of any other receipts and credits.

3.    PAYMENTS BY NON-OPERATOR

      Each party shall pay all such bills within fifteen (15) days after receipt
      thereof.  If payment is not made within such time,  the unpaid balance may
      bear  interest  at the rate of six per cent  (6%) per  annum  until  paid.
      Operator  shall have and be entitled to a prior lien on all the rights and
      interests  of  Non-Operator  in  said  joint  properties,  the  production
      therefrom,  and the material and equipment thereon,  to secure the payment
      by Non-Operator of Non-Operator's portion of cost, purchases, and expenses
      of developing  and operating the joint property as herein  provided.  Upon
      request  Operator  may  require  Non-Operator  to  advance  his  share  of
      estimated cash outlay for the current month's operations.

4.    AUDITS

      Payment of any such bills shall not prejudice the right of Non-Operator to
      protest or question the correctness  thereof.  All statements  rendered to
      Non-Operator  by Operator  during any calendar year shall be  conclusively
      presumed to be true and correct after eighteen months  following the close
      of any such calendar year, unless within said eighteen months Non-Operator
      takes written exception thereto and makes claim on Operator for adjustment
      or commences an audit of Operator's  accounts and records  relating to the
      accounting hereunder. Failure on the part of Non-Operator to make claim on
      Operator for adjustment,  or to commence an audit within such period shall
      establish  the  correctness  thereof and preclude the filing of exceptions
      thereto or the making of claims for adjustment  thereon.  A  Non-Operator,
      upon notice in writing to Operator and all other Non-Operators, shall have
      the  right  to audit  Operator's  accounts  and  records  relating  to the
      accounting  hereunder,  within eighteen months next following the close of
      any calendar year.  Non-Operator  shall have six months next following the
      examination  of the  Operator's  records  within  which  to  take  written
      exception to and make any and all claims on Operator.  The  provisions  of
      this paragraph shall not prevent  adjustments  resulting from the physical
      inventory of property as provided for in Section VI, Inventories, hereof.


                      II. DEVELOPMENT AND OPERATING CHARGES

      Per Well Basis:

A.    (1)   $15 per day for each drilling  well,  beginning on the date the well
            is spudded and terminating  when it is on production  or is plugged,
            as the case may be,  except that no charge  shall be made during the

      $30.00 per day for each seismograph reflection party.

      $30.00 per day for each seismograph refraction party.

            as producing oil wells.

      (3)   Wells  permanently  shut down but on which  plugging-operations  are
            deferred,  shall  be  dropped  from  overhead  schedule  at the time
            shutdown is effective.  When such wells are plugged,  overhead shall
            be charged at the  producing  well rate during the time required for
            the plugging operations.

      (4)   Wells being  plugged back  or drilled  deeper shall  be included  in
            overhead schedule the same as drilling wells.

      (5)   Various  wells may be shut down  temporarily  and later  replaced on
            production.  If  and  when a well  is  shut  down  (other  than  for
            proration)  and not  produced  or worked upon for a period of a full
            calendar  month,  it shall not be included in the overhead  schedule
            for such month.

      (6)   Salt water disposal wells shall not be included in overhead schedule
            as producing wells.

      The above  specific  overhead  rates may be  amended  from time to time by
      agreement  between  Operator and  Non-Operator  if, in practice,  they are
      found to be insufficient or excessive.

      It is specifically  understood that the above Overhead rates apply only to
      Drilling  and  Producing  Operations  and are not  intended  to cover  the
      construction  or  operations  of  additional  facilities  such as, but not
      limited to, gasoline plants,  compressor  plants,  repressuring  projects,
      salt water disposal  facilities,  major road  construction  projects,  and
      similar installations. If at any time any or all of these become necessary
      to the  operation  a separate  agreement  will be reached  relative  to an
      overhead charge and allocation of District Expense.

13.   WAREHOUSE HANDLING CHARGES

      A handling  charge to cover the cost of handling  material into and in the

      material  received or receivable by each party and  corresponding  credits
      will be made by the Operator to the joint account,  and such credits shall
      appear in the monthly statement of operations.

4.    SALES TO OUTSIDERS

      Sales to outsiders of material from the joint  property  shall be credited

      (b)   At 75% of current new price less  depreciation  consistent  with its
            usage  on  and  service  to  the  joint  property  if  material  was
            originally charged to the joint property as secondhand at 75% of new
            price.

3.    OTHER USED MATERIAL

      Other used material (Condition "C"), being material which:

      (a)   After  reconditioning  will  be  further  serviceable  for  original

<PAGE>

2.    NOTICE

      Notice of intention to take inventory  shall be given by Operator at least
      ten (10) days before any inventory is to begin, so that  Non-Operator  may
      be represented when any inventory is taken.

3.    FAILURE TO BE REPRESENTED

      Failure of Non-Operator to be represented at the physical  inventory shall
      bind Non-Operator to accept the inventory taken by Operator,  who shall in
      that event furnish Non-Operator with a copy thereof.

                  hereinafter collectively referred to as "H-S" and individually
                  as a member of the H-S Group),

         WITNESSETH THAT WHEREAS:

         A. By Agreement  dated May 28,  1959,  the parties  hereto  agreed on a
program for the exploration and development for oil, gas and other  hydrocarbons
of  certain  lands  situated  in the  Northwest  Territories  and  in the  Yukon
Territory of Canada,  all as more  particularly  described in said Agreement and
all subject to the terms, conditions and provisions as therein contained.

         B. Pursuant to paragraph  3.1 (B)(a) of Article III of said  Agreement,
H-S is to drill a minimum of five (5) exploratory  wells on the lands subject to
said Agreement,  of which at least one such well shall be located on the Western
Block of the properties (as that term is defined in said Agreement),  consisting
of Permits Nos. 1006, 1007, 1132, 1133 and 1135.

         C. As a result of present  information,  it now appears that a required
well drilled on said Western Block would not be to the mutual  advantages of the
parties hereto.

         NOW,  THEREFORE,  for and in  consideration  of the sum of Ten  Dollars
($10.00)  paid  by H-S to each  member  of the  C-M-O  Group  and of the  mutual
benefits  to be  obtained  and of other  good and  valuable  consideration,  the
receipt and  sufficiency  of all of which are hereby  acknowledged,  the parties
hereto hereby agree that said Agreement  shall be modified and  supplemented  as
follows:

1.       H-S shall have no  obligation  under said Agreement dated May 28, 1959,
to C-M-O, or otherwise,  to drill any of the five (5) exploratory wells referred
to in paragraph 3.1 (B)(a) of Article III  of said  Agreement  on  said  Western
Block.


<PAGE>

2.       H-S shall in respect of any operations required to be carried out by it
pursuant to Article III of the said Agreement dated May 28, 1959, carry blow out
insurance with a reputable  insurance company or companies in the minimum amount
of $1,000,000.00  and with a maximum  deductible of $25,000.00 in respect of any
one claim.

3.       Expenditures incurred by H-S in respect of any blow out which occurs in
operations  conducted by H-S pursuant to Article III of the said Agreement dated
May 28, 1959, whether incurred before or after the date of this agreement, shall
be  included  in the  total  cost  of the  exploratory  program  referred  to in
paragraph  3.1  (B)(b)  of  the  said  Agreement,   after  deduction  from  such
expenditures of any amount received by H-S pursuant to the insurance required to
be carried by H-S pursuant to clause 2 of this amending  agreement.  For greater
clarity it is  acknowledged  that any deductible up to the maximum  specified in
clause 2 of this amending agreement which H-S is required to pay on the occasion
of any claim  pursuant  to such  insurance  shall be included in the cost of the
said exploratory  program. In addition,  the cost of premiums in respect of such
insurance shall also be included in the cost of the said exploratory program.

4.       The well known as Home Signal  C.S.P.  Celibeta  No. 2  well  shall  be

<PAGE>

         c)       The Carried Interest Account presently stands at approximately

         d)       Operations on the Block A lands are governed  by the  Existing
                  Agreements.


III.     RENTALS

                  Columbia  will  reimburse  the Farmors on a per diem basis for
         all  rentals  attributable  to the Block I lands  from the date  hereof
         until  Columbia  has earned its interest in the Block I lands as herein
         provided.   Columbia   will  also   reimburse   the   Farmors  for  its
         proportionate  share of the rentals  attributable to the Block II lands
         on a per diem basis from and after the date hereof.  After Columbia has
         earned its interest hereunder rentals shall be shared by the parties in
         accordance with the Existing Agreements.


IV.      TEST WELL

                  Columbia undertakes, during the 1976-77 winter drilling season
         to make its best  efforts to  commence a well (Test Well) at a location
         of its choice, but in proximity to the North Beaver River YT I-27 well,
         and will thereafter, at its sole cost, risk and expense, drill the same
         to a depth  sufficient  to test the Nahanni  Formation or to a depth of
         10,000  feet  sub-sea,   whichever  occurs  first  (hereinafter  called
         Contract  Depth),  and  upon  reaching  Contract  Depth  will  test and
         complete  or abandon the same in  accordance  with  generally  accepted
         oilfield  practice and  applicable  government  regulations.  If due to
         circumstances  beyond its control  Columbia  is unable to commence  the
         Test  Well  during  the  1976-77  winter  drilling   season,   Columbia
         undertakes  to  drill  the Test  Well in the  1977-78  winter  drilling
         season.


V.       SUBSTITUTIONAL WELL

                  If in the drilling and/or completing of the Test Well Columbia
         encounters  severe  operating  difficulties  of a mechanical  nature or
         impenetrable  formations  which render  further  drilling or completion
         impractical  or impossible  Columbia  shall give notice  thereof to the
         Farmors and may then abandon the well. Upon abandonment  Columbia shall
         have the right, but not the obligation,  to commence within 60 days the
         drilling of a like well in close proximity to the Test Well and in this
         event the substitute well shall be deemed to be the Test Well.



<PAGE>

VI.      ABANDONMENT

                  If  Columbia  wishes  at any time to  abandon  the  Test  Well
         Columbia  shall give notice  thereof to the Farmors.  The Farmors shall
         have the right, jointly or severally, within 48 hours of receipt of the
         notice to elect to take over and attempt to complete the Test Well.  If
         the Farmor(s)  successfully  completes  the well for the  production of
         petroleum substances, Columbia shall assign to the Farmor(s) all of its
         right,  title and  interest  in the Test Well and the  spacing  unit on
         which the same is located.  Concurrently, the Farmor(s) shall reimburse
         Columbia for the estimated salvage value of the salvagable material and
         equipment   assigned  to  the  Farmor(s)  and  Columbia  shall  not  be
         responsible for any subsequent abandonment or completion costs.


VII.     DATA

                  In the drilling of the Test Well Columbia shall furnish to the
         Farmors on a current basis all pertinent  data relating to the drilling
         and/or  completion of the Test Well.  All  information  acquired by the
         parties hereto relating to the Test Well shall be held  confidential by
         the parties and shall not be divulged to any third party unless  agreed
         to in writing by each of the Farmors and Columbia.


VIII.    COMPLETION

                  In the event the Test Well is capable of producing natural gas
         in paying  quantities,  Columbia  undertakes at its sole cost, risk and
         expense,  to provide and install the necessary  facilities to place the
         Test Well on production.


IX.      INTEREST EARNED FROM DOME, AMOCO AND ALMINEX

                  Upon drilling the Test Well to Contract  Depth and  completing
         or abandoning  same as herein  provided,  Columbia will have earned and
         Dome, Amoco and Alminex will assign to Columbia,  an undivided one-half
         of each of such parties  beneficial  interest (working interest) in and
         to the Block I lands.



<PAGE>

X.       INTEREST EARNED FROM CANADA SOUTHERN

                  Upon drilling the Test Well to Contract  Depth and  completing
         or abandoning the same as herein provided,  Canada Southern will reduce
         its  50%  carried  interest  in and to the  Block  A  lands  (excepting
         therefrom  Sections 27 and 50 contained  within Lease No.  411-68) to a
         33.33%  carried  interest  and convert  the  remaining  16.66%  carried
         interest to a 16.66% working  interest which will thereupon be assigned
         to Columbia.  In addition,  Canada  Southern will assign to Columbia an
         undivided  16.66%  working  interest  in  and  to  Sections  27  and 50
         contained within Lease No. 411-68.


XI.      CARRIED INTEREST

                  Upon  Columbia   earning  its  interest  as  herein  provided,
         Sections 27 and 50 contained  within Lease No.  411-68 shall  thereupon
         also be subject  to the  Carried  Interest  Provisions  so that  Canada
         Southern's  resultant  interest  in all of the Block A lands will be in
         the nature of a 33.33%  carried  interest and be subject to the Carried
         Interest Provisions.

                  For greater  certainty,  each of the working  interest owners,
         including Columbia, will thereafter bear its proportionate share of the
         obligation to advance the operational costs on Canada Southern's behalf
         so that the obligations and beneficial  interest of each party would be
         as follows:

         (a)      Section 27 contained within Lease No. 411-68:

                  Company              Obligation        Beneficial Interest

         Canada Southern                  0.00%          33.33% carried interest

         (b)      Balance of the Block I lands:

         Alminex                          1.87%           1.25% working interest

XII.     ALLOCATION OF REVENUE

                  Notwithstanding anything herein contained to the contrary, the
         parties agree that all revenue  generated from the Block I lands (after
         deducting all royalties and operating costs) shall accrue  concurrently
         and proportionately to:

         (1)      Columbia  until Columbia has recovered the total cost incurred
                  by Columbia related to the drilling, completing and placing on
                  production of the Test Well and,

         (2)      the Farmors  (excluding  Canada  Southern)  until such time as
                  they have  recovered  an amount  equal to that  portion of the
                  Carried  Interest Account which is attributable to the Block I
                  lands. Columbia shall be entitled to conduct an audit of those
                  amounts  which  have been  included  in the  Carried  Interest
                  Account.

                  For greater certainty it is intended that the Carried Interest
         Account (as the same  relates to the Block I lands)  shall be recovered
         by the parties advancing the same concurrently and proportionately with
         Columbia recovering its costs as herein stated. Thereafter, all revenue
         generated  from the Block I lands (after  deducting  all  royalties and
         operating  costs),  shall  accrue to  Columbia  in an  amount  equal to
         Columbia's  beneficial  interest  in the  spacing  unit from  which the
         revenue  is  obtained  and the  balance  shall  accrue  to the  Farmors
         (excepting  Canada  Southern)  until  such  time  as the  Farmors  have
         recovered  the balance of the  Carried  Interest  Account.  Thereafter,
         revenue shall be shared by the parties in accordance with their working
         or carried  interest,  whichever  the case may be, in the spacing  unit
         from which such revenue is obtained.



<PAGE>

XIII.    OPERATIONS

                  After Columbia has earned its interest  hereunder,  operations
         on the Block I lands shall be conducted in accordance with the Existing
         Agreements as hereby amended, and Columbia shall act as Operator. It is
         proposed that the overhead rates in the existing  accounting  procedure
         be revised to more accurately  reflect  current rates.  Notwithstanding
         the above, the parties  undertake to enter into a more formal agreement

                  Expenditure  from the  Operator  give to the Operator a notice
                  requiring  the  Operator  to call a meeting  of the  Operating
                  Committee to consider the  variation of the Detailed  Estimate

10.7     APPROVED PROGRAMME  TO  CONTINUE  UNLESS  MODIFIED  Notwithstanding the
giving of a notice by the  Operator  pursuant to Clause 10.6 hereof the Operator
shall continue with the conduct of the programme  approved  unless and until the

proposed  well  location  in the form of a square or  rectangular  figure  whose
length  does not  exceed  twice its width with the well  location  in the centre
thereof.  Before receiving such information the Non-Consenting Party must pay to
the consenting Parties five (5) times what such Non-Consenting  Party's share of
the cost of conducting  the operations in the said selected area would have been

such operations in which it did not participate on the Concession (regardless of
whether  all or a  portion  of the lands  comprising  the  Concession  have been
surrendered)  which would have been charged to such Party had it participated in
all such operations theretofore conducted on the Concession.

15.      INDEPENDENT OPERATIONS
         DRILLING OF WELLS

15.1     APPLICATION OF PART  The provisions  of  this  Part 15  relate  to  the
drilling or deepening of wells on the Concession  which are not, or which are in
excess of,  operations  necessary to keep the  Concession  in good standing free
from forfeiture or cancellation under the Petroleum Act and which are not agreed
to by all  Parties.  Any Party or  Parties  nay carry out such  operations  upon
complying with the requirements of this Part.

15.2     DEFINITION OF TERMS  In this Part 15 the following words shall have the
meanings hereinafter assigned: -

         (i)      "PRODUCER  OF PETROLEUM  IN PAYABLE  QUANTITIES"  means a well
                  which would considering the cost of production operations, the
                  probable life of the well, the available market for production
                  therefrom  and the price,  nature and quality of the petroleum
                  produced, commercially and economically warrants the continued
                  taking of production from such well.

         (ii)     "DEVELOPMENT  WELL" means a well which at the time of spudding
                  in is located at a distance of less than eight (8)  kilometres
                  from any well (whether located on the concession or not) being
                  or  capable  of  being a  Producer  of  Petroleum  in  Payable
                  Quantities from the same zone to which it is intended to drill
                  the proposed  well or from any  shallower  zone whether or not
                  such other well is  completed  as a Producer of  Petroleum  in
                  Payable Quantities.

         (iii)    "EXPLORATORY WELL" means either -

                  (a)      a well which at the time of spudding in is located at
                           a distance of eight (8)  kilometres  or more from any
                           other well (whether located on the Concession or not)
                           being or capable of being a Producer of  Petroleum in
                           Payable  Quantities  from the  same  zone or from any
                           shallower  zone than the zone to which it is intended
                           to drill the proposed well whether such other well is
                           a Producer of Petroleum in Payable Quantities or not;
                           or


<PAGE>

                  (b)      a well which at the time of spudding in is located at
                           a  distance  of less than eight (8)  kilometres  from
                           such other well but which it is  proposed to drill to
                           a deeper  formation  than  that  from  which the said
                           other well is  Producing  or is capable of  Producing
                           Petroleum in payable quantities.

                           in  such  further   Work   without   being  deemed  a
                           Non-Desiring  Party  shall be reduced to  forty-eight
                           (48) hours;

                  (ii)     If the Desiring  Party or Parties  shall not commence
                           the actual deepening  stimulation  testing or further
                           testing of the said well  within  thirty (30) days of
                           the  election  of  the  Non-Desiring   Party  not  to
                           participate   in   such   further   Work   then   the
                           consequences  provided by Clause 15.8 shall follow as
                           if such further Work was a drilling  operation  dealt

16.      DISPOSITION OF PRODUCTION

16.1     SEPARATE OWNERSHIP OF PETROLEUM  Each  Party  shall  have the right and
obligation to receive and take in kind as its own property at the Delivery Point
and  separately  dispose  of  its  share  of all  Petroleum  produced  from  the
Concession  except  such  Petroleum  as may be  used in  drilling,  development,
testing,  producing,  processing,   compression  and  other  operations  on  the
Concession and in preparing,  treating and transporting  Petroleum for marketing
and except such Petroleum as may be unavoidable  lost. A Non-Operator may confer
upon the Operator  authority to deliver to the buyer thereof all or part of that
Non-Operator's share of Petroleum produced from the Concession.

16.2     RIGHT TO SEPARATE FACILITIES A Party shall have the right to construct,
maintain and operate  within the  Concession  all necessary  facilities  for the
purpose of taking in kind and  separately  disposing  of its share of  Petroleum
produced from the Concession  provided they are so  constructed,  maintained and
operated as not to interfere with other  operations able to be carried out under
this  Agreement.  Any extra  expenditure  or costs  incurred by the  Operator by
reason  of the  delivery  in  kind of any  portion  of  such  Petroleum  to such
facilities shall be borne by the owner of such portion.

16.3     UNDERLIFTING PROCEDURE If any Party fails to take in kind or separately
dispose of any and all of such  Party's  share of  Petroleum  produced  from the
Concession, the Operator, subject to any restrictions imposed by law, may: -

         (a)      dispose of the quantity of Petroleum concerned  by sale to the
                  purchasers  of the share  of the Petroleum  produced  from the
                  Concession  of  the  other  Parties   and  pro  rata  to  such
                  purchasers in  proportion  to  the  quantity of such Petroleum
                  being purchased  by  them.  Any  such  quantity  of  Petroleum
                  involved shall be so  sold at the same  point or points and at
                  the same arms  length  price  or  prices  at which  such other
                  Petroleum is being sold.  Any such  purchase or  sale shall be
                  subject to  revocation  at will by the  Party owning the share
                  involved  (without  however  affecting  any  contract  of sale
                  already  entered  into with  respect to such  Petroleum).  Any
                  contract of sale relating to such share and entered into  with
                  a third  party  or  third  Parties  shall  be  for  a term not
                  exceeding such reasonable period of time as is consistent with
                  the minimum needs of the industry under the  circumstances but
                  in no event shall any such contract be for a term in excess of
                  one (1) year.  The price or  proceeds of sale of the Petroleum
                  concerned  (less all  costs and  expenses of and incidental to
                  such sale not incurred for the  Joint  Account) shall promptly
                  be paid over to the owner of such Petroleum; or


<PAGE>

         (b)      store such  Petroleum on the  Concession  in existing  storage
                  facilities  or in  storage  facilities  established  for  such
                  purpose and the cost of such storage and of  establishing  any
                  such storage facilities shall be borne by the Party owning the
                  Petroleum so stored;

                  or

         (c)      otherwise deal with such Petroleum  as the Operating Committee
                  may determine.

16.4     PAYMENTS DIRECT TO EACH PARTY  Subject to  Clause 17  hereof,  where  a
Party  enters into a contract of sale for all or part of its share of  Petroleum
produced  from the  Concession,  that Party shall be entitled to receive  direct
from the  purchaser  thereof all sale  proceeds due under such contract of sale.
Each Party shall pay or cause to be paid all  royalties  and other like payments
attributable to its interest or share of Petroleum produced.

16.5     EXTRA EXPENDITURE   Any  extra  expenditure  incurred  by  a  Party  in
receiving  or  separately  disposing  of its  share  of the  Petroleum  from the
Concession shall be borne by such Party.

17.      DEFAULTS IN PAYMENT

17.lA    NOTICE OF DEFAULT If any Party  including the Operator  (herein  called
the "Defaulting  Party") fails to make any payment as required by this Agreement
or by any of the  other  Joint  Venture  Documents  on or  before  the due  date
thereof,  the Operator  shall upon becoming aware of such failure give notice by
telex cable or  telegram  of such  failure to the  Defaulting  Party.  If at the
expiration of two (2) days after the receipt or deemed receipt of such notice by
the Defaulting  Party payment of the amount due by the Defaulting  Party remains
unpaid the Operator shall thereupon give a notice of the default to all Parties.

Such notice ("the Default Notice") shall contain a statement of the amount owing
by the Defaulting  Party and for the purpose of this Clause 17 all Parties other
than  the  Defaulting  Party  are  herein  referred  to as  "the  Non-Defaulting
Parties".

17.1B    PAYMENT BY OPERATOR In the event that the  payment which the Defaulting
Party  has  failed to make is a  payment  due  under  any of the  Joint  Venture
Documents to a person who is not a Party,  the Operator  shall if so directed by
the Operating  Committee  pay the same to such person.  Any amount so paid shall
constitute a debt  immediately  due and payable by the  Defaulting  Party to the
Operator.  Notwithstanding the foregoing, the Operator may make any such payment
without  the prior  approval  of the  Operating  Committee  where such action is
necessary to preserve the Concession or to save it from forfeiture.


<PAGE>

17.2     DEFAULTING PARTY MAY BE SUED  Without prejudice to any other remedy for
or consequence of default provided for in this Agreement,  the Operator shall if
so directed by the  Operating  Committee in any Court of competent  jurisdiction
sue a  Defaulting  Party  (including  without  limiting  the  generality  of the
foregoing, any Party removed from the position of Operator for failing to pay or
contribute,  its proportionate share of the costs and expenses herein mentioned)
for the recovery of any moneys payable to the Operator by that Defaulting  Party
under any of the Joint  Venture  Documents  remaining  unpaid by the  Defaulting
Party at the  expiration of fourteen (14) days after the delivery of the Default
Notice to the Defaulting Party.

17.3     NON-DEFAULTING PARTIES TO CONTRIBUTE If at the end of the fourteen (14)
day  period  referred  to in Clause  17.2  hereof  the  Operator  shall not have
received  from the  Defaulting  Party the amount due ("the Unpaid  Amount") plus
interest at the Default  Interest Rate the Operator may and shall if so directed
by the  Operating  Committee  require  the  Non-Defaulting  Parties  to pay  the
Operator the Unpaid Amount.  The amount to be reimbursed by each  Non-Defaulting
Party shall bear the same ratio to the Unpaid Amount as does such Non-Defaulting
Party's Working  Interest bear to the aggregate of the Working  Interests of all
the  Non-Defaulting  Parties.  A Party  which does not pay all amounts due by it
under  Clause 17.3 hereof  shall be regarded as a  Defaulting  Party and all the
provisions  of this Clause 17 shall apply to such Party in respect of any amount
not so paid.

17.4     RIGHTS OF CONTRIBUTING PARTIES A  Non-Defaulting  Party  (including the
Operator  in its  capacity as a Party)  which pays to the  Operator or bears any
amount  payable by it under Clause 17.3 hereof is  hereinafter  called "a Paying
Party" and shall be deemed to have advanced such amount to the Defaulting  Party
on the terms that it is immediately  repayable and may sue the Defaulting  Party
to recover the same but without prejudice to any other rights and remedies.  The
amount owing by a Defaulting  Party to a Paying Party shall bear interest at the
Default  Interest  Rate from the date the Paying  Party made the  payment  under
Clause 17.3 to the date it has recovered the same in full.

17.5     CROSS CHARGE  For the purposes of better securing the payment:-

         (a)      to the Operator of any amount due and  payable  to it pursuant
                  to any of the Joint Venture Documents;

         (b)      to each of the Paying Parties of any amount due and payable to
                  it pursuant to Clause 17.4 hereof;

each of the Parties shall forthwith  execute and deliver a Deed in substantially
the form and to the  effect of the form of Deed set out in  Annexure  "B" hereto
("Clause 17 Cross Charge") and shall obtain all necessary consents and approvals
in relation  thereto and shall duly  register  the same and shall file or record
such other documents or notices relating thereto,  in such  jurisdictions as may
be required by law to perfect the security given thereby.


<PAGE>

17.6     SUSPENSION OF RIGHTS OF DEFAULTING PARTY  Subject to the  provisions of
Clause 9.7(3) hereof a Defaulting  Party shall not be entitled  either to attend
or vote through its representative at any meeting of the Operating  Committee or
the Parties or otherwise be consulted  with respect to Work unless and until any
amount payable by that  Defaulting  Party in accordance with the terms of any of
the Joint Venture  Documents  shall have been received in full or the default is
otherwise rectified or waived.

17.7     DEFAULT OF OPERATOR IN PAYMENT  In the event  that the  Operator  is in
default in payment  of any amount  payable by it under any of the Joint  Venture
Documents in its capacity as a  Non-Operator  and for any reason the Operator is
not removed  from that  position,  then the rights  prescribed  for the Operator
under this Clause 17 and  elsewhere  herein shall be exercised for and on behalf
of the  Non-Defaulting  Parties by such person as the Operating  Committee shall
determine and such person shall be deemed to be the Operator for such purpose.

17.8     APPLICATION OF DEFAULTING PARTY'S FUNDS  Upon default  by any  Party in
the payment of any moneys payable under any of the Joint Venture Documents,  the
Operator shall  (notwithstanding  anything  contained herein or in any Clause 17
Cross  Charge  to the  contrary,  and  without  prejudice  to other  rights  and
remedies),  retain any  moneys  which may be held for such  Defaulting  Party or
which come to the hands of the Operator on behalf of such Defaulting  Party, and
apply such moneys  until the amount owed by such  Defaulting  Party as aforesaid
has been paid in full.

17.9     OPTION TO PURCHASE DEFAULTING PARTY'S INTEREST  If at the  end of sixty
(60)  days  from  the due  date on  which  moneys  were to have  been  paid by a
Defaulting  Party to the  Operator or any  Non-Defaulting  Party such moneys and
interest  thereon  remain  unpaid  by such  Defaulting  Party,  then each of the
Non-Defaulting  Parties  shall have the option and each Party which may become a
Defaulting Party hereby grants to each of the Non-Defaulting  Parties the option
to purchase  the Working  Interest  of the  Defaulting  Party at the date of the
exercise of the option (and if more than one Non-Defaulting  Party exercise such
option)  in the  proportions  which  the  respective  Working  Interests  of the
Non-Defaulting  Parties exercising the option bear to the total of their Working
Interests (or in such other  proportions  as such  Non-Defaulting  Parties shall
agree) upon and upon the following terms and conditions:-

         (a)      The  option  shall  be  exercisable  for so long as a  default
                  giving  rise to the  option  has  not  been  cured  and may be
                  exercised by notice in writing to the Defaulting  Party signed
                  by those  Non-Defaulting  Parties  which wish to exercise  the
                  option.


<PAGE>

         (b)      The  purchase  price  shall be a sum equal to  eighty  percent
                  (80%) of the value of the Working  Interest of the  Defaulting
                  Party at the date of the  exercise of the  option.  Each Party
                  hereby  agrees that the  difference  between the full value of
                  the Working  Interest of the Defaulting  Party and the selling
                  price  under this Clause  constitutes  a  pre-estimate  of the
                  liquidated   damages   which   will   be   sustained   by  the
                  Non-Defaulting  Parties by reason of breach of this  Agreement
                  by the Defaulting Party.

         (c)      If within thirty (30) days of the  exercise  of the option the
                  Defaulting  Party and the purchasers  have not agreed upon the
                  purchase price  for the  Working Interest  of  the  Defaulting
                  Party, the value of the  Working Interest  of  the  Defaulting
                  Party  at  the  date  of  the  exercise  of  option  shall  be
                  determined  by the nominee of the  Chairman for the time being
                  of the Australian Petroleum Exploration Association Limited on
                  the  application  of either the  Defaulting Party  or the Non-
                  Defaulting  Parties  exercising  the  option.  In making  such
                  determination  the said  nominee  shall be acting as an expert
                  and not an  arbitrator and  his  decision  shall be  final and
                  binding upon all Parties. For the purposes hereof,  the value
                  of the Defaulting Party's Working Interest shall be determined
                  on the basis that the Joint Venture is a going concern and the
                  price payable is that which would be paid by a willing but not
                  anxious  buyer to a willing but not  anxious seller dealing at
                  arm's length.

         (d)      The  completion  of the purchase  shall be effected as soon as
                  reasonably practicable after the determination of the purchase
                  price pursuant to  paragraphs  (b) and (c)  hereof.  Upon such
                  completion the purchasers shall be at liberty  to deduct  from
                  the purchase price the amount required to discharge or satisfy
                  liabilities  secured by any  charge or  encumbrance  over  the
                  Working  Interest  of  the  Defaulting  Party  and the several
                  liabilities at the date of completion of the  Defaulting Party
                  under this Agreement or other Joint Venture Documents.  Any of
                  the purchasers  shall also  be  entitled  to  deduct  from the
                  purchase  price the  amount of  any stamp  duty payable on any
                  transfer or  other  instrument  arising  from  the exercise of
                  option.

         (e)      Upon and in exchange  for the payment to it of the balance (if
                  any) of the purchase price pursuant to the preceding paragraph
                  (d) hereof,  the Defaulting  Party shall forthwith do all such
                  acts and things and execute and deliver to the  purchasers all
                  such transfers  deeds and other  documents as are necessary to
                  give effect to and complete  the sale  pursuant to this Clause
                  17.9.

         (f)      If the  Defaulting  Party fails to act in the manner  provided
                  for in the preceding  paragraph  (e), then a person  nominated
                  for the purpose by the  Non-Defaulting  Parties exercising the
                  option  shall be and be deemed to be the agent and attorney of
                  the Defaulting Party for all purposes necessary to give effect
                  to the sale pursuant to this Clause 17.9.


<PAGE>

         (g)      In the event  that a Court  of  competent  jurisdiction  shall
                  determine  that the  method of  determination  of the purchase
                  price pursuant to  paragraph  (b)  of  this  Clause 17.9 would
                  constitute  a penalty or  for any other  reason would have the
                  consequence  of rendering  void or voidable the option in this
                  Clause 17.9  contained then the  purchase  price,  pursuant to
                  this Clause 17.9,  shall be and be  deemed to be the value of
                  the  Working  Interest of the Defaulting  Party at the date of
                  the exercise of the option  less the  damages sustained by the
                  Non-Defaulting  Parties by reason of the breach of contract by
                  the Defaulting Party  such damages being  such amount as shall
                  be agreed between the Defaulting Party and the  Non-Defaulting
                  Parties or in the absence of agreement, as shall be determined
                  by a Court of competent jurisdiction.

         (h)      If the purchase price is determined  pursuant to the preceding
                  paragraph  (g)  hereof and  differs  from the  purchase  price
                  determined  pursuant to  paragraphs  (b) and (c) hereof and if
                  completion has already taken place,  then the balance (if any)
                  of the purchase  price  payable to the  Purchaser  pursuant to
                  paragraphs  (d) and (e)  hereof  shall  be  re-calculated  and
                  appropriate   adjustments  (if  any)  of  the  amount  payable
                  pursuant to  paragraph  (e) hereof as between  the  Defaulting
                  Party and the Purchasers shall be forthwith paid and received.

         (i)      Any sale  pursuant  to this  Clause  shall be  subject  to all
                  Governmental  consents and  approvals  required by law. If any
                  such consent or approval is refused any  contract  constituted
                  by an exercise of option hereunder shall cease to have further
                  force or effect.

         (j)      For the  purpose of this Clause  17.9 a  Non-Defaulting  Party
                  which has not notified the other Non-Defaulting Parties within
                  thirty (30) days after the option becoming exercisable that it
                  wishes to exercise the option shall not thereafter be entitled
                  to join in the  exercise of the option  without the consent of
                  the  Non-Defaulting  Party or Parties  which have as aforesaid
                  indicated their wish to exercise the option.

18.      WITHDRAWAL

Interests bear to the aggregate of their Working Interests. If some only of such
Parties accept such offer or if the acceptance of any accepting Party is limited
in percentage, then the interest of the Withdrawing Party or the portion of such
interest  remaining  after the  allocation of any limited  percentages  accepted
shall be distributed  amongst the other accepting Parties in the proportion that
their  respective  Working  Interests  bear to the  aggregate  of their  Working
Interests of such  Parties or in such other  proportions  as such Parties  agree

         done in the  course  of Work on or  before  the  effective  date of its
         withdrawal; and
(iii)    the royalties mentioned in Clause 3.3 hereof.

         The Withdrawing  Party shall remain  responsible  for such  obligations

is not in default under any of the Joint Venture  Documents may at any time sell
transfer  or assign to any other  Party or to an  Affiliate  or to any person or
entity not a party to this  Agreement,  its Working  Interest in the whole or in
part PROVIDED HOWEVER THAT: -

(a)      No assignment  of a part of a Party's  Working  Interest  shall be made
         unless  it is a  uniform  assignment  of the  whole of that part of the

         Commonwealth or  Northern Territory Governments  unless  such  increase

                  such form or forms as the Operating Committee   shall  approve

         Parties and an executed  counterpart shall be delivered to the assignee
         promptly thereafter.

19.3     ASSIGNMENT TO A CROWN CORPORATION  Notwithstanding  the  provisions  of
Clause  19.2  hereof an  assignee  being a  subsidiary  of  Australian  Industry

                                  ANNEXURE "A"

- --------------------------------------------------------------------------------


                              ACCOUNTING PROCEDURE

                              1. GENERAL PROVISIONS

1.       DEFINITIONS

         Any term used  herein  shall  have the  meaning  assigned  to it by the
         Operating Agreement to which this Accounting Procedure is attached.

2.       STATEMENTS AND ACCOUNTS

         The  Operator  shall on or before  the last day of a month  debit  each
         Non-Operator  for its  proportionate  share of costs  and  expenditures
         during  such  preceding  month  and  forward  to each  Non-Operator  an
         accounting statement showing the details of all charges and credits for
         the Joint Account.

3.       PAYMENTS BY NON-OPERATOR

         Each Party shall pay its proportion of all such accounts within fifteen
         (15) days after receipt of such accounting statement. If payment is not
         made within such time the unpaid  balance  shall bear interest from the
         end of the said period at the Default Interest Rate until paid.

4.       ADJUSTMENTS

         Payments  of any such  accounts  shall not  prejudice  the right of any
         Non-Operator to protest or question the correctness thereof. Subject to
         the  exception  noted in  Clause  5 of this  Section  1 all  statements
         rendered to any  Non-Operator  by the Operator during any calendar year
         shall conclusively be presumed to be true and correct after twenty-four
         (24) months  following  the end of any such calendar year unless within
         the said twenty-four (24) month period such Non-Operator  takes written
         exception thereto and makes a claim on the Operator for adjustment. The
         failure  on the  part of  such  Non-Operator  to  make a  claim  on the
         Operator  for  adjustment   within  such  period  shall  establish  the
         correctness  thereof and preclude it from filing objections  thereto or
         making claims for  adjustment  thereon.  The  provisions of this Clause
         shall not prevent  adjustments  resulting  from  physical  inventory of
         property as provided for in Section 6 "Inventories" hereof.

5.       AUDITS

         (i)      A  Non-Operator upon not less than thirty (30) days  notice in
                  writing to the Operator and all the other  Non-Operators shall
                  have the right to  audit the Operator's  accounts and  records
                  relating to the  accounting  hereunder  for  any calendar year
                  within the twenty-four (24) month  period following the end of
                  such calendar year provided however that the Non-Operator must
                  take written exception  to and make a  claim upon the Operator
                  for all discrepancies  disclosed by the  said audit within the
                  said twenty-four (24) month period.  Where  there  are  two or
                  more   Non-Operators   the   Non-Operators  shall  make  every
                  reasonable effort to conduct joint or simultaneous audits in a
                  manner which will  result in a minimum of inconvenience to the
                  Operator.

         (ii)     The Operator shall cause its external auditors to carry out an
                  audit of the  accounts  and  records of the Joint  Venture and
                  records  relating to the accounting  hereunder for each period
                  of twelve calendar months ending on each 30th June. Such audit
                  shall be carried out as soon as is reasonably possible and the
                  Operator  shall  forward a copy of the audit  report  given by
                  such  auditors to each  Non-Operator.  The costs of such audit
                  shall be for the Joint Account.

         unusual  causes over which the Operator has no control the Operator may
         charge  the  Parties  for the  required  materials  on the basis of the
         Operator's   direct  cost  and  expense   incurred  in  procuring  such
         materials,  in  making  it  suitable  for use,  and in moving it to the

         Non-Operators  for the material and/or equipment  acquired  pursuant to
         this provision,  whereupon any Non-Operator  shall have the right by so

         said Non-Operators.

         the value of the material received or receivable by each Party, and the
         corresponding  credits  will  be  made  by the  Operator  to the  Joint
         Account.  Such  credits  shall  appear  in  the  monthly  statement  of

3.       SALES TO OUTSIDERS

         Sales to  outsiders  of  material  from  the  Concession  or the  Joint

         by the purchaser for defective  material or otherwise  shall be charged
         back for the Joint Account if and when paid by the Operator.

         current new price (plus sales tax, if any).

         serviceable condition suitable for re-use without reconditioning:-

         (a)      At seventy-five percent (75%) of current new price if material
                  was charged for the Joint Account as new, or

         (b)      At  sixty-five  percent (65%) of current new price if material
                  was originally  charged for the Joint Account as secondhand at
                  seventy-five percent (75%) of the new price.

4.       OTHER USED MATERIAL

         Used  material  (Condition  "C") at fifty  percent (50%) of current new
         price, being used material which:-

         (a)      After reconditioning will be further serviceable for  original

         prices.

7.       TEMPORARILY USED MATERIAL

         shall be priced on a basis  that will  leave a net charge for the Joint
         Account consistent with the value of the service rendered.

         part  of  the  Joint  Facilities  inventories  shall  be  taken  by the
         Operator,  subject  to the  Agreement  which  shall  include  all  such
         material as is ordinarily  considered  controllable by Operators of oil
         and gas properties. Written notice of intention to take inventory shall
         be given by the Operator at least thirty (30) days before any inventory
         is to begin  so that  the  Non-Operators  may be  represented  when any
         inventory is taken.

         Failure of any  Non-Operator  to be represented  at an inventory  shall
         bind such  Non-Operator  to accept the inventory taken by the Operator,

         A  reconciliation  of  inventory  shall  be  made by the  Operator  and
         approved by the Operating  Committee.  Inventory  adjustments  shall be
         made by the Operator for averages and shortages, but the Operator shall
         be held  accountable  to the  Non-Operators  only for  shortages due to
         negligence on its part.

         Special  inventories  may be taken  at the  expense  of a  Non-Operator
         whenever  there is any sale or change of interest in the Concession and

         provision that any such other mortgage,  charge,  security  interest or

(a)      fifteen (15) days from the Due Date of that Indebtedness; and

(b)      twenty-one (21) days from the date written notice has been given by any
         Non-Defaulting  Participant or the Operator to any Special  Chargee who
         has the benefit of any outstanding  Special Charges from the Defaulting
         Participant   notifying   that  Special   Chargee  of  the   Defaulting
         Participant's Indebtedness,

then,  unless and until such  Indebtedness  is paid in full, any  non-defaulting

5.       The Operator  or any  other Participant  entitled pursuant  to Clause 3
hereof to take  action to  enforce  the said  charge  may at any time  after its
entitlement  to enforce the said charge arises  appoint a Receiver or a Receiver

assets of the Defaulting  Participant charged hereunder (hereinafter called "the
Charged  Property") and may in like manner from time to time remove any Receiver
so appointed and appoint another in his stead.  Any such  appointment or removal
shall be in writing.  A Receiver so  appointed  shall be deemed the agent of the
Defaulting  Participant  which  shall  be  solely  responsible  for his acts and
defaults and for his remuneration.

6.       The Receiver  or Operator  or  any  other party  to this  Deed entitled
pursuant  to  Clause  3  hereof  to take  action  to  enforce  the  said  charge

the Receiver) may exercise any or all of the following  powers,  authorities and
discretions  (which shall be interpreted  separately and not be reference to one
another) in addition to all other powers,  authorities and discretions conferred

         that purpose to raise and use money on the Charged Property in priority
         to this charge;

(c)      to direct  any buyer  under a Sales  Contract  to which the  Defaulting
         Participant  is a  party  to pay  direct  to the  Enforcing  Party  any
         proceeds of sale due to that Participant;

(d)      to  receive  store  and/or  sell  what  otherwise  would  have been the
         Defaulting  Participant's  share of products  derived  from or produced
         from the  Concession  (provided  such products are not the subject of a
         Sales Contract) on terms and conditions similar to those which may have
         been obtained by any other  Participant and the exercise of such powers
         by the Receiver shall not be prevented or hindered by the terms hereof;

(e)      to let or lease any or all of the Charged Property;

(f)      to sell or concur in selling the Charged  Property or any part  thereof

         sale  into  effect by  conveying  and  transferring  in the name and on
         behalf of the Defaulting Participant or otherwise;

(g)      to execute all such contracts, deeds, transfers and other assurances in
         the name and on behalf of the Defaulting Participant for the purpose of
         carrying into effect any of the powers and authorities conferred on the
         Enforcing Party as he may see fit;

(h)      to make any arrangement or compromise which he thinks expedient;  and

(i)      generally  to do or cause to be done such acts and things with  respect

         damage which happens thereby) as he may think necessary and which could
         have  been  done or  caused  to be done by any  Receiver  if he had the

<PAGE>

Any person paying money to or otherwise  dealing with the Enforcing  Party shall
not be  concerned to enquire  whether any event has  occurred to  authorise  the
Enforcing  Party to act and the  receipt  of any such  Enforcing  Party  for any
moneys arising under any of the powers aforesaid shall be a sufficient discharge
without obliging the persons paying the same to see to the application thereof.

7.       The proceeds realised from the  exercise  of the  powers referred to in
Clause 6 hereof for the sale thereof shall be applied:-

FIRSTLY:          in payment of  any obligations  having priority  to the charge
                  hereby created;

SECONDLY:         in  payment  of  all  costs,   charges  and  expenses  of  and
                  incidental to the appointment of the Receiver and the exercise
                  by the Enforcing Party of all or any of the  powers  aforesaid
                  including the reasonable remuneration of the Enforcing Party;

THIRDLY:          to the Operator the amount of any  Indebtedness  to the extent
                  that  the same has not  been  paid by  other  Participants  in
                  accordance  with the  provisions  of  Clause  17.3 of the Palm
                  Valley Operating  Agreement,  and to the Participants who have
                  paid their full  proportionate  share of any  Indebtedness  on
                  behalf of the Defaulting  Participant  in accordance  with the
                  provisions  of  Clause  17.3  of  the  Palm  Valley  Operating
                  Agreement such proportionate share of any Indebtedness so paid
                  and not otherwise recovered;

FOURTHLY:         in payment of any outstanding obligation;  or liability of the
                  Defaulting  Participant  under   any  of  the   Joint  Venture
                  Documents; and then

FIFTHLY:          all amounts  (if any)  recovered in excess of the sum required
                  to discharge the  Indebtedness  shall subject to proper claims
                  enforceable under other encumbrances be paid to the Defaulting
                  Participant.

Save as  aforesaid  neither the  Non-Defaulting  Participants  nor the  Operator
(unless it be a  Participant  in default)  shall be under any  liability  to the
Enforcing Party for his remuneration costs, charges or expenses or otherwise.

8.       Claims  arising  from  the  priority  described  within  the  paragraph
"THIRDLY"  of Clause 7 hereof  shall as between such claims rank pari passu with
the result that if the amount  realised in any such action shall be insufficient
to discharge  all  Indebtedness  described  in such clause the amount  available
therefor  shall be  apportioned  among  the  claimants  in  proportion  to their
respective claims.

9.       The charge  created  by  this  Deed  shall  be  deemed  a  running  and
continuing  security  notwithstanding  any  settlement  on account of particular
amounts or any other matter or thing  whatsoever  and shall remain in full force
until a final  discharge  thereof  has been  executed  by the  Operator  and the
Non-Defaulting Participants.

10.      Insofar as this charge pertains  to the  Participating  Interest of the
Defaulting  Participant   enforcement  hereof  shall  also  be  subject  to  the
provisions of Clauses 19.4.2(a),  19.4.2(b), 19.4.2(c), 18 and 28.10 of the Palm
Valley  Operating  Agreement and in the event of any conflict  between this Deed
and a Deed in the form of Annexure "C" to the Palm Valley Operating Agreement on
the one hand and the said Clauses of the Palm Valley Operating  Agreement on the
other hand the latter shall prevail.

11.      Each Participant shall  from  time  to  time  execute and  deliver such
further charges and other documents  (including  without limiting the generality
of the foregoing,  mortgages or charges collateral hereto of its interest in all
or some of the titles  constituting  the  Concession in a form  registrable as a
legal  mortgage  or charge  under the laws  pursuant  to which  such  titles are
granted) as may be  reasonably  requested  by any chargee in order to confirm or
effectuate the intent and purposes of this Deed. Each of the Parties  granting a
charge  hereunder  shall  forthwith  duly register or record this Deed and shall
file  or  record  such  other  notice  or  documents  relating  thereto  in such
jurisdictions as may be required by law to perfect the security hereby given.

other  Participants that it has full power to enter into this Deed and to charge
the Charged Property as provided herein.

and the  Operator  to  execute  and  deliver  all  such  assurances,  deeds  and
instruments  and do all such acts and things  whatsoever  as may be necessary to
release and discharge the charge hereby  created to enable a Participant to sell
and  transfer  its  Participating  Interest  where such sale and  transfer is in
accordance with the Palm valley Operating  Agreement and to duly register,  file
or record all such notices or documents  relating thereto in such  jurisdictions
as may be required by law to perfect such release,  discharge or substitution as
aforesaid.

14.      Each and every  power  and  remedy   herein   specifically   given to a
non-defaulting  Participant  or the Operator shall be in addition to every other
power and remedy now or  hereafter  existing  at law or in equity,  and each and
every power and remedy may be exercised from time to time and  simultaneously as
often and in such order as may be deemed expedient. All such powers and remedies
shall be cumulative, and the exercise of one shall not be deemed a waiver of the
right to exercise  any other power or remedy and no renewal or  extension of any
Indebtedness shall impair any such power or remedy or shall be construed to be a
waiver of any default or an acquiescence therein.

15.      It is acknowledged  and agreed  that no covenant or  charge is given or
created under Clause 2 of this Deed by any  subsidiary  of  Australian  Industry
Development Corporation which becomes a Participant, although such subsidiary on
becoming  a  Participant   shall  have  the  benefit  of  this  Deed  and  as  a
non-defaulting  Participant shall be entitled to enforce the rights and remedies
of a Non-Defaulting Participant hereunder.

16.      All notices required  to  be given  by or  pursuant to  this Deed shall
unless  otherwise  provided  in this  Deed  be  given  in  accordance  with  the
provisions of Clause 27 of the Palm Valley Operating Agreement.

17.      This Deed shall take effect  as of the date first  above set forth when
one or more  counterparts  thereof shall have been signed by each of the Parties
hereto and such signed  counterparts  shall have been  delivered by each of such
Parties to each of the other such Parties.  Upon  termination of the Palm Valley
Operating  Agreement  each of the Parties to whom a charge is granted  hereunder
shall  promptly  execute  and  deliver a release  and  discharge  of such charge
provided that there be in fact no Indebtedness then owing under such charge.

18.      This Deed shall be governed by and be construed in accordance  with the
laws of the Northern  Territory  of Australia  and for the purposes of this Deed
the Parties hereby consent and submit to the  jurisdiction of the Courts of such
Territory.

of such budget or that expenditures on any item in such approved  programme will
or are likely to exceed  the  budget or the  Detailed  Estimate  of  Expenditure
approved or deemed approved for such item by more than TEN PERCENT (10%) thereof

the  giving of a notice by the  Operator  pursuant  to Clause  10.6  hereof  the
Operator  shall continue with the conduct of the programme  approved  unless and
until the Operating  Committee modifies the approved programme so as to avoid or
reduce such excess  expenditure.  The Operator  shall be entitled to recover any
expenditures  duly  incurred by it under  Clause 10.6 hereof or this Clause 10.7

period of thirty  (30)  clear  days shall be deemed a refusal on its part of its
right to participate in the drilling of the proposed well.

15.5              Unanimous Participation  If all Parties receiving  such notice
elect to  participate  in the said  well and so  advise  the  Desiring  Party or
Parties of such  election  then the said well  shall be drilled by the  Operator
under the terms of this  Agreement  with the costs  thereof  being for the Joint
Account.

15.6              Non-Desiring Party If any Party receiving the aforesaid notice
shall  refuse  expressly  or  impliedly  to  participate  in the drilling of the
proposed well (any such party being  hereinafter  referred to as a "Non-Desiring
Party") the provisions hereinafter provided shall apply.

15.7              Operator  For Sole Risk  Drilling The Operator for the purpose
of Notified  Operations  shall if the Operator of the  Concession  is a Desiring
Party be such  Operator.  In the event that the Desiring Party or Parties do not
include such Operator then the Desiring Party or Parties voting in proportion to
their  respective  Working  Interests in the  Concession  shall by majority vote
elect a Party to be the Sole  Risk  Operator  for the  purpose  of the  Notified
Operations.  This  Agreement  shall bind the parties  participating  in Notified
Operations  and the Party  acting  as Sole  Risk  Operator  in  respect  of such
Notified  Operations as though it was a separate Operating Agreement applying to
such  Notified  Operations.   Such  Sole  Risk  Operator  shall  if  appropriate
co-operate with the Operator of the Concession for the purpose of satisfying all
recording and other  obligations  of the  Concession in relation to the Notified
Operations.

15.8              Time For Commencement The Desiring Party or Parties shall have
one hundred  and twenty  (120) clear days after the end of the thirty (30) days'
period  referred to in Clause 15.4 in which to commence the Notified  Operations
at the  location  specified  in the said notice and unless an  extension of this
period is agreed to by the Non-Desiring  Party or Parties if the actual drilling
of the well is not  commenced  within the said  period or within  any  extension
thereof  so agreed,  the right of the  Desiring  Party or  Parties  to  commence
drilling  will be lost and all rights  flowing from the giving of the notice and
the  election to  participate  in the Notified  Operations  of the well shall be
terminated.

15.9              Obligation of Desiring Parties If the Sole Risk Operator shall
commence  the  Notified  Operations  at the  location set out in the said notice
within the said period referred to in Clause 15.8 then:-

         (a)      it shall  proceed  with  diligence  to drill  such well to the
                  depth or  geological  target  specified in the notice (or such
                  lesser depth as may be dictated by  operational  hazard) in an
                  attempt to find and produce Petroleum;

         (b)      the entire cost and risk of the Notified  Operations  shall be
                  borne by the  Desiring  Party or Parties (and if more than one
                  then  pro  rata in  proportion  to  their  respective  Working
                  Interests)  and the Desiring  Party or Parties  shall keep the
                  Concession  free and clear of all liens  and  encumbrances  of
                  every  kind  and  character  created  by or  arising  from the
                  Notified  Operations  and the Desiring  Party or Parties shall
                  indemnify  and  keep  indemnified  the  Non-Desiring  Party or
                  Parties  against  each and every  liability  arising from such
                  operations;


<PAGE>

         (c)      in the  event  that  such  well  is not  completed  after  the
                  Desiring  Party or Parties shall have  terminated the drilling
                  of the well then the Desiring  Party or Parties shall plug and
                  abandon the well  pursuant to the terms and  provisions of all
                  the   applicable   laws   rules   and   regulations   and  the
                  environmental standards currently prevailing in the region and
                  shall  restore the location by filling and  levelling  the rig
                  cellar  and all  slush  pits  and by  removing  all  leasehold
                  equipment  material and debris placed  thereon by the Desiring
                  Party or Parties;  all being at the sole cost risk and expense
                  of the Desiring Party or Parties.

15.10             Conformity to Spacing  Patterns  Without the mutual consent of
all Parties  holding a Working  Interest no Petroleum  shall be produced  from a
source of supply  from  which a well  located  elsewhere  on the  Concession  is
producing or scheduled to produce unless such well conforms to the then existing
well  spacing  pattern  for such  source of supply  laid down by a  governmental
authority or by the Operating Committee.

15.11             Penalties  Payable By  Non-Desiring  Parties  If  pursuant  to
Clause 15.9 hereof any well is drilled and  completed by the  Desiring  Party or
Parties then the following provisions shall apply:-

         (a)      The Desiring Party or Parties shall be entitled to sell all of
                  the  Non-Desiring  Party's  or  Parties'  share  of  Petroleum
                  production  of such well and to retain  the  proceeds  of sale
                  thereof for the use of the Desiring  Party or Parties pro rata
                  as hereinabove  provided until such proceeds (after  deducting
                  all royalties payable thereon all taxes on production  thereof
                  except income taxes and all operating  expenses  applicable to
                  the  Non-Desiring  Party's or Parties'  interest in production
                  all hereinafter called "Deductible Expenses") shall equal:-

                  (a)      200% in the case of an Appraisal Well; or

                  (b)      1000% in the case of an Exploration Well;

                  of the amount which would have been the  Non-Desiring  Party's
                  or Parties' share of the cost of drilling  testing  completing
                  and equipping  such well for  production if such well had been
                  carried  out by the  Desiring  Party or Parties  for the Joint
                  Account of the Parties (which share of costs is hereinafter in
                  the whole of this  clause  called "the  Non-Desiring  Share of
                  Cost").


<PAGE>

         (b)      When the Desiring Party or Parties shall have received:-

                  (a)      200% in the case of an Appraisal Well; or

                  (b)      1000% in the case of an Exploration Well;

                  of the Non-Desiring  Share of Cost the said well together with
                  all equipment therein or used in connection  therewith and all
                  of the  Petroleum  production  therefrom  shall  thereafter be
                  owned in the same manner as  Petroleum  production  from wells
                  drilled  pursuant to this Agreement  (other than wells drilled
                  under  Clause 15 hereof) and shall  thereafter  be operated by
                  the Operator  constituted under Clause 5 hereof in like manner
                  as other  wells  (other  than wells  drilled  under  Clause 15
                  hereof) under this Agreement.

         (c)      In determining the costs and expenses incurred by the Desiring
                  Party  or  Parties  in the  drilling  testing  completing  and
                  equipping of the said well the Accounting  Procedure  shall be
                  followed.

         (d)      Within 120 clear days  after the said well is  completed  as a
                  producer of  Petroleum  the  Desiring  Party or Parties  shall
                  furnish  to the  Non-Desiring  Party or Parties  complete  and
                  detailed  statements  setting out the cost of drilling testing
                  completing  and equipping  such well for  production  the said
                  well  together with an inventory of the material and equipment
                  in and on the said well for use in connection therewith.

         (e)      During  the  time the  Desiring  Party or  Parties  are  being
                  reimbursed as above  provided,  the Desiring  Party or Parties
                  shall render monthly  statements to the Non-Desiring  Party or
                  Parties  reflecting  for each  calendar  month  the  costs and
                  expenses   incurred  in  operating  the  well,  the  Petroleum
                  produced and saved  therefrom,  the proceeds  derived from the
                  sale  thereof and the  quantity of Petroleum in storage at the
                  end of the said month.  Such  statement  covering the previous
                  month's  operating  shall be rendered within thirty (30) clear
                  days following the close of such calendar month.

         (f)      The Non-Desiring  Party or Parties shall have the right at all
                  reasonable  times to inspect and audit the Desiring Party's or
                  Parties' books and records  including run tickets meter charts
                  and invoices pertaining to any matter of account hereunder.


<PAGE>

         (g)      In the event that the Desiring  Party or Parties are unable to
                  recover  from the  Non-Desiring  Party or Parties its or their
                  share of cost the Desiring Party or Parties shall own pro rata
                  all the material equipment and supplies placed or installed by
                  the  Desiring  Party or  Parties  on the  said  well or on the
                  Concession in connection  therewith  PROVIDED  HOWEVER that if
                  such  material  equipment and supplies have a salvage value in
                  excess of the unrecovered  amounts to which the Desiring Party
                  or Parties are entitled as hereinbefore provided,  such excess
                  shall be owned by the Parties  hereto in  proportion  to their
                  Working Interests at the time.

15.12             Deepening of Wells Every prior  provision of this Clause 15
having regard to a proposal to drill a well shall apply equally to a proposal to
deepen a well which has been drilled on the Concession (as a dry hole or without
encountering  Petroleum  in  Payable  Quantities  or which has ceased to produce
Petroleum) except that:-

         (a)      (i)      If the rig with  which the  well was  drilled or  any
                           other  rig  capable  of  carrying  out the  deepening
                           operation  is on  location  at the time a  notice  is
                           given  the time  within  which the Party to which the
                           notice is given by the Desiring Party or Parties must
                           agree  to  participate  in the  drilling  of the well
                           without  being deemed a  Non-Desiring  Party shall be
                           reduced to forty-eight (48) hours;

                  (ii)     If the Desiring  Party or Parties  shall not commence
                           the actual  deepening of the said well within  thirty
                           (30) days of the election of the  Non-Desiring  Party
                           not  to   participate  in  such  deepening  then  the
                           consequences  provided by Clause 15.8 shall follow as
                           if the deepening  operation were a drilling operation
                           dealt with by that Clause;

         (b)      In the event that as a result of the deepening  operations the
                  well is drilled and completed by the Desiring Party or Parties
                  as a Producer  of  Petroleum  in Payable  Quantities  then the
                  provisions   of  Clause  15.11  shall  apply  subject  to  the
                  modification  that  the  Non-Desiring  Party's  share  of cost
                  defined in Clause  15.11(a) shall be calculated with regard to
                  the cost of deepening  testing  completing  and  equipping the
                  said  well  from the  depth  to  which it has been  previously
                  drilled.

16.               DISPOSITION OF PRODUCTION

16.1              Separate  Ownership of Petroleum  Each Party hereto shall have
the right to take in kind or  separately  dispose of its share of all  Petroleum
produced from the  Concession  except such Petroleum as may be used in drilling,
development, testing, producing, processing, compression and other operations on
the  Concession  and in  preparing,  treating  and  transporting  Petroleum  for
marketing and except such Petroleum as may be  unavoidable  lost. A Non-Operator
may confer upon the Operator  authority  to deliver to the buyer  thereof all or
part of that Non-Operator's  share of Petroleum produced from the Concession and
a  Party  shall  be  deemed  to have  exercised  its  rights  to take in kind or
separately dispose of Petroleum hereunder upon the making of such a contract for
the sale of such Petroleum to the extent of the quantities sold.

16.2              Right to Separate  Facilities  The  Parties  holding a Working
Interest  shall have the right to  construct,  maintain  and operate  within the
Concession  all  necessary  facilities  for the  purpose  of  taking  in kind or
separately  disposing of their respective shares of Petroleum  produced from the
Concession  provided they are so constructed,  maintained and operated as not to
interfere with other operations able to be carried out under this Agreement. Any
extra expenditure or costs incurred by the Operator by reason of the delivery in
kind of any portion of such Petroleum to such  facilities  shall be borne by the
owner of such portion.

16.3              Underlifting Procedure  If any  Party  hereto fails to take in
kind or  separately  dispose of any and all of such  Party's  share of Petroleum
produced from the Concession,  the Operator, subject to any restrictions imposed
by law, may either:-

         (a)      dispose of the quantity of Petroleum  concerned by sale to the
                  purchasers of the share  of  the  Petroleum  produced from the
                  Concession  of  the  other  Parties   and  pro  rata  to  such
                  purchasers in proportion  to  the  quantity of such  Petroleum
                  being  purchased by  them.  Any  such  quantity  of  Petroleum
                  involved shall be so  sold at the  same point or points and at
                  the same arms length  price or  prices  at  which  such  other
                  Petroleum  is being sold.   Any such purchase or sale shall be
                  subject to revocation  at will  by the Party  owning the share
                  involved  (without  however  affecting  any  contract  of sale
                  already entered into with  respect  to  such  Petroleum).  Any
                  contract of sale relating to  such share and entered into with
                  a third Party  or  third  Parties  shall  be  for  a  term not
                  exceeding such reasonable period of time as is consistent with
                  the minimum needs of the industry under the  circumstances but
                  in no event shall any such contract be for a term in excess of
                  one (1) year.  The price or proceeds of  sale of the Petroleum
                  concerned  (less all costs  and expenses of  and incidental to
                  such sale not incurred for the  Joint  Account) shall promptly
                  be paid over to the owner of such Petroleum; or


<PAGE>

         (b)      store such  Petroleum on the  Concession  in existing  storage
                  facilities  or in  storage  facilities  established  for  such
                  purpose and the cost of such storage and of  establishing  any
                  such storage facilities shall be borne by the Party owning the
                  Petroleum so stored.

16.4              Payments  Direct to Each Party  Subject  to  Clause 17 hereof,
where a Party  enters  into a  contract  of sale for all or part of its share of
Petroleum produced from the Concession,  that Party shall be entitled to receive
direct from the  purchaser  thereof all sale proceeds due under such contract of
sale.  Each  Party  shall pay or cause to be paid all  royalties  and other like
payments attributable to its interest or share of Petroleum produced.

16.5              Extra  Expenditure  Any  extra  expenditure  incurred  in  the
taking in kind or separate  disposition  by a Party  hereunder  of such  Party's
share of the Petroleum from the Concession shall be borne by such party.

17.               DEFAULTS IN PAYMENT

17.1              Notice of Default If any Party including the Operator  (herein
called the  "Defaulting  Party")  fails to make any  payment to the  Operator as
required by this Agreement on or before the due date thereof, the Operator shall
give notice thereof to all Parties. Such notice shall contain a statement of the
amount owing by the  Defaulting  Party and for the purpose of this Clause 17 all
Parties  other  than  the  Defaulting  Party  are  herein  referred  to as  "the
Non-Defaulting Party".

17.2              Defaulting Party May be Sued  Without  prejudice  to any other
remedy  for or  consequence  of  default  provided  for in this  Agreement,  the
Operator  may in its own name in any  Court of  competent  jurisdiction  sue any
Party  (including  without  limiting the generality of the foregoing,  any Party
removed  from the  position of Operator  for  failing to pay or  contribute  its
proportionate share of the costs and expenses herein mentioned) for the recovery
of any share of authorised  costs and expenses and interest  remaining unpaid by
the Defaulting  Party at the expiration of fourteen (14) days after the delivery
of the notice referred to in Clause 17.1 hereof to the Defaulting Party.


<PAGE>

17.3              Certain  Non-Defaulting Parties to Contribute If at the end of
the  fourteen  (14) day period  referred to in Clause  17.2 hereof the  Operator
shall not have received from the  Defaulting  Party the amount due plus interest
at the Default Interest Rate the Operator may request the Non-Defaulting Parties
to reimburse the Operator such amount due plus interest as aforesaid. The amount
to be reimbursed by each Non-Defaulting Party (if it is bound to do so or elects
to do so)  shall  bear  the  same  ratio  to the  total  amount  not paid by the
Defaulting  Party as does such  Non-Defaulting  Party's Working Interest bear to
the  aggregate of the Working  Interests of all the  Non-Defaulting  Parties who
contributed  or were liable to  contribute  to the cost of the Work to which the
payment  which  is in  default  refers.  Except  as  hereinafter  provided,  the
Non-Defaulting  Parties  shall not be  compelled  to  contribute  the amounts so
requested  by the  Operator  but while  either  Oilmin,  Krewliff,  Transoil  or
International is Operator then Oilmin,  Krewliff,  Transoil,  and  International
shall each  contribute  or bear the amount so requested  from it by the Operator
within  fifteen (15) days of such request by the Operator.  If at the end of the
said fifteen (15) day period a Non-Defaulting Party other than Oilmin, Krewliff,
Transoil and  International has not contributed or borne the amount so requested
from it by the Operator, and either Oilmin, Krewliff,  Transoil or International
is  Operator  then the  Operator  may require  Oilmin,  Krewliff,  Transoil  and
International  to  contribute  or bear  the  amounts  not so  contributed  (plus
interest)  within  twenty-one  (21) days of such  request  and the  amount to be
contributed  or borne by each  shall  be in the  same  ratio to the  total to be
contributed  by them as the Working  Interests  of each is to the total of their
Working  Interests.  Notwithstanding  any provision herein to the contrary,  the
Operator  may  relieve  Oilmin,  Krewliff,  Transoil or  International  of their
respective obligations under this Clause 17.3 hereof.

17.4              Rights  of  Contributing  Parties   A   Non-Defaulting   Party
(including  the  Operator in its capacity as a Party) which pays to the Operator
or bears all of the  amounts due by it under  Clause 17.3 hereof is  hereinafter
called "a Paying Party" and may to recover the same but without prejudice to any
other  rights and  remedies,  invoke the  provisions  of this Clause 17. A Party
which does not pay all  amounts  due by it under  Clause 17.3 hereof or which it
has  elected  to pay  under  Clause  17.3 but does  not pay when  due,  shall be
regarded as a Defaulting  Party and the provisions of this Clause 17 shall apply
in  respect to the amount not so paid and the Party not paying the share in full
shall for all  purposes  of this Clause 17 and the Cross  Charge  referred to in
Clause 17.5, be a Defaulting Party.

17.5              Cross Charge  For the  purposes  of  the  better  securing  of
payment:-

         (a)      to the Operator of any amount  in default and interest accrued
                  thereon pursuant to the terms hereof;


<PAGE>

         (b)      to the Paying Parties  of any debt due  and payable to them or
                  any of them pursuant to Clause 17.3 hereof;

each of the Parties holding a Working Interest shall forthwith  execute and duly
register a Deed in substantially  the form and to the effect of the form of Deed
set out in Annexure "B" hereto  ("Clause 17 Cross  Charge") and shall obtain all
necessary  consents and  approvals in relation  thereto and shall file or record
the  same  and  such  other  documents  or  notices  relating  thereto  in  such
jurisdiction as may be required by law to perfect the security given thereby.

17.6              Suspension of Rights of  Defaulting Party  Notwithstanding any
provision  hereof to the  contrary,  a  Defaulting  Party  shall not be entitled
either to attend vote at any meeting of the  Operating  Committee or the Parties
or otherwise  be  consulted  with respect to Work unless and until the amount in
default of such Party plus  interest in  accordance  with the terms hereof shall
have been  received in full or the default is otherwise  rectified or waived and
for voting  purposes  only the Working  Interest of a Defaulting  Party shall be
proportionately distributed amongst the Paying Parties.

17.7              Default of Operator In Payment  In the event that the Operator
is in default in payment of any amount due from the Operator to meet  authorised
costs and expenses hereunder and for any reason the Operator is not removed from
that position,  then the rights prescribed for the Operator under this Clause 17
and elsewhere herein shall be exercised for and on behalf of the  Non-Defaulting
Parties by such person as they  unanimously  nominate  and such person  shall be
deemed to be the Operator for such purpose.

17.8              Application  of Defaulting  Party's Funds  Upon default by any
Party in the payment to the  Operator or upon default by the Operator as a Party
in making a payment due hereunder, the Operator shall (notwithstanding  anything
contained  herein or in any Clause 17 Cross Charge to the contrary,  and without
prejudice to other rights and remedies), retain any moneys which may be held for
such  Defaulting  Party or which come to the hands of the  Operator on behalf of
such  Defaulting  Party,  and apply such  moneys  until the amount  owed by such
Defaulting  Party,  plus interest in accordance with the terms hereof,  has been
thus paid to the Operator.

17.9              Option to Dilute Interest of Defaulting Party If at the end of
forty-five (45) days from the due date on which moneys were to have been paid by
a Defaulting  Party to the  Operator  such moneys and  interest  thereon  remain
unpaid by such Defaulting  Party, then provided no action has been taken under a
Cross Charge referred to in Clause 17.5 hereof to appoint a Receiver  thereunder
of the interest of the  Defaulting  Party and  provided  all the  Non-Defaulting
Parties have  contributed  to the Operator  pursuant to Clause 17.3 hereof their
respective  shares of such amount and interest due but unpaid,  each Party which
may become a Defaulting  Party hereby grants to the Paying  Parties an option to
dilute the Working Interest of the Defaulting Party concerned in accordance with
Clauses  17.10 to  17.14  hereof  inclusive.  Such  option  to  dilute  shall be
exercised by the unanimous  resolution of the Paying Parties. The Operator shall
serve notice of such resolution on the Defaulting  Party and such dilution shall
become effective on the service of such notice.

17.10             Dilution Formula  If the Paying  Parties  exercise  the option
under Clause 17.9 hereof to dilute the interest of the Defaulting Party, the new
Working  Interest of the Defaulting  Party at the time of such dilution shall be
calculated in accordance with the following formula:-

                  New Working Interest =  C   x 100%;
                                          TC

                  Where C           =       the  total of all contributions made
                                            by  the  Defaulting  Party  to  Work
                                            since the  date  of  this  Agreement
                                            together with the Deemed Expenditure
                                            and the Acquired  Expenditure of the
                                            Defaulting Party; and

                  Where                     TC = the total of all  contributions
                                            male by all Parties (who are Parties
                                            at   that   time)    including   the
                                            Defaulting  Party to Work (including
                                            amounts  contributed to the Operator
                                            under Clause 17. 3 hereof) since the
                                            date of this Agreement together with
                                            the  Acquired   Expenditure  of  all
                                            Parties  (who  are  Parties  at  the
                                            time) the Deemed Expenditure.


<PAGE>

                  For the purpose of this Clause 17.10,  the Deemed  Expenditure
shall be TWENTY MILLION DOLLARS ($20,000,000.00) and the Deemed Expenditure of a
Defaulting  Party shall be  determined by  multiplying  TWENTY  MILLION  DOLLARS
($20,000,000.00)  by the Working  Interest of the Defaulting  Party in existence
immediately prior to such dilution.

                  For  the  purpose  of  this  Clause   17.10,   where  a  Party
("Acquiring Party") has acquired a Working Interest from another Party ("Selling
Party") the Acquiring Party shall have an Acquired Expenditure which shall be an
amount equal to the product of the  proportion  of the then Working  Interest of
the Selling  Party so acquired  multiplied by the  contributions  of the Selling
Party  to  Work  since  the  date  of  this  Agreement  up to the  date  of such
acquisition, and the contributions of the Selling Party to Work shall be reduced
by such Acquired Expenditure.

17.11             Distribution  of Working  Interest  Available on Dilution  The
difference  between the new Working  Interest of the Defaulting Party determined
in accordance  with Clause 17.10 hereof and its Working  Interest  prior to such
dilution  shall be  distributed  to the Paying  Parties in the proportion of the
payments made by each to the Operator under such Clause 17.3 without any payment
or  consideration  except as stated  herein  being  made by such  Parties to the
Defaulting Party.

17.12             Extinguishment  of  Amount  Due   Upon  such  a  dilution  and
distribution being made, the liability of the Defaulting Party to pay the amount
plus  interest  which  had been due and  owing to the  Operator  shall be deemed
extinguished and such amount deemed to be paid.

17.13             Repayment of Loan Funds Where a Defaulting Party had mortgaged
or charged its Working Interest to secure the repayment by it of moneys borrowed
for  expenditure by it on Work, and at the date of  distribution of part of such
Working  Interest  under Clause 17.10  hereof to a  Non-Defaulting  Party moneys
remain to be repaid by the Defaulting  Party under such mortgage or charge,  the
Non-Defaulting Party shall be bound to repay a proportionate part of such moneys
remaining to be repaid with such  proportionate  part being in the same ratio to
the  total to be  repaid  at the  date of  distribution  as is the  ratio of the
Working Interest  distributed to such Non-Defaulting  Party to the total Working
Interest of the Defaulting Party immediately prior to such distribution.


<PAGE>

17.14             Interest Distributed Clear of Charges  Except as  provided  in
Clause 17. 13 hereof,  any Working  Interest so distributed to a  Non-Defaulting
Party shall be distributed  free of any mortgage or  encumbrance  granted by the
Defaulting Party and except as stated in Clause 17.13 hereof the  Non-Defaulting
Parties  shall not  become  responsible  for the  repayment  of any loans or the
satisfaction of any obligations owed by the Defaulting Party.

                                  ANNEXURE "A"

- --------------------------------------------------------------------------------

                              ACCOUNTING PROCEDURE

                              1. GENERAL PROVISIONS

1.       DEFINITIONS

         Any term used  herein  shall  have the  meaning  assigned  to it by the
         Operating Agreement to which this Accounting Procedure is attached.

2.       STATEMENTS AND ACCOUNTS

         The Operator shall debit each Non-Operator on or before the last day of
         a month for its  proportionate  share of costs and expenditures  during
         such  preceding  month.  Such  accounts  will show the  details  of all
         charges and credits for the Joint Account.

3.       PAYMENTS BY NON-OPERATOR

         Each Party shall pay its proportion of all such accounts within fifteen
         (15) days after  receipt  thereof.  If payment is not made  within such
         time the unpaid  balance  shall bear  interest from the end of the said
         period at the Default Interest Rate until paid.

4.       ADJUSTMENTS

         Payments  of any such  accounts  shall not  prejudice  the right of any
         Non-Operator to protest or question the correctness thereof. Subject to
         the  exception  noted in  Clause  5 of this  Section  1 all  statements
         rendered to any  Non-Operator  by the Operator during any calendar year
         shall conclusively be presumed to be true and correct after twenty-four
         (24) months  following  the end of any such calendar year unless within
         the said twenty-four (24) month period such Non-Operator  takes written
         exception thereto and makes a claim on the Operator for adjustment. The
         failure  on the  part of  such  Non-Operator  to  make a  claim  on the
         Operator  for  adjustment   within  such  period  shall  establish  the
         correctness  thereof and preclude it from filing objections  thereto or
         making claims for  adjustment  thereon.  The  provisions of this Clause
         shall not prevent  adjustments  resulting  from  physical  inventory of
         property as provided for in Section 6 "Inventories" hereof.

5.       AUDITS

         (i)      A  Non-Operator  upon not less than thirty (30) days notice in
                  writing to the Operator and all the other  Non-Operators shall
                  have the right to audit the  Operator's  accounts  and records
                  relating to the  accounting  hereunder  for any calendar  year
                  within the twenty-four  (24) month period following the end of
                  such calendar year provided however that the Non-Operator must
                  take  written  exception to and make a claim upon the Operator
                  for all  discrepancies  disclosed by the said audit within the
                  said  twenty-four  (24) month  period.  Where there are two or
                  more   Non-Operators  the   Non-Operators   shall  make  every
                  reasonable effort to conduct joint or simultaneous audits in a
                  manner which will result in a minimum of  inconvenience to the
                  Operator.


<PAGE>

         (ii)     The Operator shall cause its external auditors to carry out an
                  audit of the Operator's  accounts and records  relating to the
                  accounting hereunder for each period of twelve calendar months
                  ending on each 30th June.  Such audit  shall be carried out as
                  soon as is reasonably  possible and the Operator shall forward
                  a copy of the  audit  report  given by such  auditors  to each
                  Non-Operator.  The costs of such audit  shall be for the Joint
                  Account.

         Operator's   direct  cost  and  expense   incurred  in  procuring  such
         materials,  in  making  it  suitable  for use,  and in moving it to the
         location, provided, however, that notice in writing is furnished to the

         Non-Operators  for the material and/or equipment  acquired  pursuant to
         this provision,  whereupon any Non-Operator  shall have the right by so
         electing  and  notifying  the  Operator  within  ten  (10)  days  after
         receiving  notice from the Operator,  to furnish in kind, or in tonnage

                  found to be either excessive or insufficient.

                   4. DISPOSAL OF LEASE EQUIPMENT AND MATERIAL

The  operator  shall be under no  obligation  to  purchase  the  interest of the
Non-Operators  in surplus new or secondhand  material.  The disposition of major
items of surplus material, such as derricks,  tanks, engines, pumping units, and
tubular goods,  shall be subject to mutual  determination by the Parties hereto;
provided the Operator shall have the right to dispose of normal accumulations of
junk and scrap material either by transfer or sale from the Concession.

         Material  purchased by either the Operator or any Non-Operator shall be

<PAGE>

         the value of the material received or receivable by each Party, and the
         corresponding  credits  will  be  made  by the  Operator  to the  Joint
         Account.  Such  credits  shall  appear  in  the  monthly  statement  of
         operations.

3.       SALES TO OUTSIDERS

         Sales to outsiders of material from the Concession shall be credited by
         the  Operator to the Joint  Account of the net amount  collected by the

         material or otherwise  shall be charged  back for the Joint  Account if
         and when paid by the Operator.

Material  purchased  by either the  Operator or any  Non-Operator  or divided in
kind, unless otherwise agreed, shall be valued on the following basis.

1.       NEW PRICE DEFINED

         New price as used in the following clauses shall have the same  meaning
         and application as that  used above in Section 3  "Basis of charges for
         the Joint Account."

2.       NEW MATERIAL

         New  materials  (Condition  "A"),  being new material  procured for the
         Joint Account but never used thereon at one hundred  percent  (100%) of
         current new price (plus sales tax, if any).

3.       GOOD USED MATERIAL

         Good used material  (Condition  "B"),  being used material in sound and
         serviceable condition suitable for re-use without reconditioning:-

         (a)      At seventy-five percent (75%) of current new price if material
                  was charged for the Joint Account as new, or

         (b)      At  sixty-five  percent (65%) of current new price if material
                  was originally  charged for the Joint Account as secondhand at
                  seventy-five percent (75%) of the new price.

4.       OTHER USED MATERIAL

         Used  material  (Condition  "C") at fifty  percent (50%) of current new
         price, being used material which:-

         (a)     After reconditioning  will be further  serviceable for original
                 function as good secondhand material (Condition "B"), or

         (b)     Is serviceable  for original  function  but  substantially  not
                 suitable for reconditioning.


<PAGE>

5.       BAD ORDER MATERIAL

         Material and  equipment  (Condition  "D") which is no longer usable for
         its  original  purpose  without  excessive  repair  cost but is further
         usable for some  other  purpose  shall be priced on a basis  comparable
         with that of items normally used for that purpose.

6.       JUNK

         Junk (Condition  "E"),  being obsolete and scrap material at prevailing
         prices.

7.       TEMPORARILY USED MATERIAL

         When the use of material is temporary  and its service does not justify
         the reduction in price as provided in Clause 3(b) above,  such material
         shall be priced on a basis  that will  leave a net charge for the Joint
         Account consistent with the value of the service rendered.

                                 6. INVENTORIES

1.       PERIODIC INVENTORIES, NOTICE AND REPRESENTATION

         At  least  annually  inventories  shall be  taken  by the  Operator  of
         material,  subject  to the  Agreement  which  shall  include  all  such
         material as is ordinarily  considered  controllable by Operators of oil
         and gas properties. Written notice of intention to take inventory shall
         be given by the Operator at least thirty (30) days before any inventory
         is to begin  so that  the  Non-Operators  may be  represented  when any
         inventory is taken.

         Failure of any  Non-Operator  to be represented  at an inventory  shall
         bind such  Non-Operator  to accept the inventory taken by the Operator,
         who shall in that event furnish such Non-Operator with a copy thereof.

2.       RECONCILIATION AND ADJUSTMENT OF INVENTORIES

         The  reconciliation  of inventory  with  charges for the Joint  Account
         shall be made by each Party at  interest,  and a list of  averages  and
         shortages  shall  be  jointly   determined  by  the  Operator  and  the
         Non-Operators.  Inventory adjustments shall be made by the Operator for
         averages and shortages,  but the Operator shall be held  accountable to
         the  Non-Operators  only  for  shortages  due  to  lack  of  reasonable
         diligence.

3.       SPECIAL INVENTORIES

         Special  inventories  may be taken  at the  expense  of the  purchaser,
         whenever there is any sale or change of interest in the Concession; and
         it shall be the duty of the Party  selling to notify all other  Parties
         hereto as quickly as possible  after the  transfer  of  interest  takes
         place.  In such  cases,  both the  seller  and the  purchaser  shall be
         represented  and shall be governed  by the  inventory  so taken,  which
         shall be taken at the cost of the purchaser.

(a)      fifteen (15) days  from  the  Due  Date  of  any  Indebtedness  of  the
         Mortgagor; and

(b)      twenty-one  (21) days from the date of receipt by all Special  Chargees
         who took a Special  Charge from the  Mortgagor of a notice which notice
         may be given at any time  after the Due Date from  another  Participant
         informing   the  Special   Chargee  that  the  Mortgagor  had  incurred
         Indebtedness,

         the  Indebtedness of the Mortgagor has not been paid by Mortgagor or by
         or at the  direction  of any  Special  Chargee  of the  Mortgagor,  the
         Operator  may  take  action  pursuant  to this  Deed in its own name to
         enforce  the charge  granted  hereby  and  exercise  the powers  herein
         contained in respect of all  Indebtedness  owing by the  Mortgagor  and
         shall  take such  action if  requested  to do so by any  Non-Defaulting
         Participant.

3.2      If the Operator  shall have been  requested to take action  pursuant to
         the preceding  provisions  and shall have refused or neglected to do so
         for a period of seven (7) days after the date of such request then (and
         only then) the Party or Parties  who made such  request  may subject to
         the rights of the other Parties  hereunder take action pursuant to this
         Deed in the name of the  Operator  or in the name or names of the Party
         or Parties who made such request to enforce the charge  granted  hereby
         in respect of all  Indebtedness  owing by the Mortgagor to all Chargees
         hereunder.

3.3      Notwithstanding  anything  hereinbefore in Clauses 3.1 to 3.4 inclusive
         and 7 hereof  to the  contrary  the  Operator  shall  not take any such
         action in respect of any Indebtedness (other than Indebtedness owing to
         the Operator as such) if directed in writing by all the  Non-Defaulting
         Participants to refrain from taking such action.

3.4      The Mortgagor hereby irrevocably  appoints the Operator (provided it is
         not a Defaulting  Participant) (and, to the extent empowered by Clauses
         3.1  to  3.3  hereof   inclusive   to  take  action   hereunder,   each
         Non-Defaulting  Participant),  as its attorney to take action on behalf
         of such  Party to  enforce  the  charge  granted  hereby in  respect of
         Indebtedness   owing  to  such  Party   including  the  making  of  any
         declaration  in respect to the stamping of this Deed and the payment of
         any stamp duty payable thereon.

4.       The first floating  charge created by this Deed shall not of itself
(subject always to the provisions of the Mereenie  Operating  Agreement)  hinder
any sale or other dealings of the Mortgagor in the ordinary course of or for the
purpose of carrying on its business of or with the  property and assets  charged
thereby prior to any Indebtedness arising.  Except as provided in Clause 6(b) of
this Deed none of the property or assets charged by this Deed, whether by way of
first  floating  charge or first fixed  charge,  shall be subject to any charge,
mortgage,  security, interest or other encumbrance ranking either in priority to
or pari passu with the charge created by this Deed.

5.       The Operator or any  other Participant  entitled  pursuant to  Clause 3
hereof to take  action to  enforce  the said  charge  may at any time  after its
entitlement  to enforce the said charge arises  appoint a Receiver or a Receiver
and Manager  (hereinafter  referred to as "the  Receiver")  of the  property and
assets of the  Mortgagor  charged  hereunder  (hereinafter  called "the  Charged
Property")  and may in like  manner  from time to time  remove any  Receiver  so
appointed  and appoint  another in his stead.  Any such  appointment  or removal
shall be in writing.


<PAGE>

6.       A Receiver  so  appointed  shall be deemed  the agent of the  Mortgagor
which  shall  be  solely  responsible  for his  acts  and  defaults  and for his
remuneration.  The Receiver or Operator or any other party to this Deed entitled
pursuant  to Clauses 3.1 to 3.4  inclusive  hereof to take action to enforce the
said charge  (hereinafter  referred to as "the Enforcing Party" which expression
shall include the  Receiver)  may exercise any or all of the  following  powers,
authorities  and discretions  (which shall be interpreted  separately and not be
reference  to one  another)  in addition to all other  powers,  authorities  and
discretions  conferred  on  him by law  and  subject  always  to the  terms  and
conditions of the Mereenie Operating Agreement:-

(a)      to take possession of, collect and get in the Charged  Property and for
         that purpose to take any  proceedings  in the name of the  Mortgagor or
         otherwise as seem expedient and to give effectual receipts  accordingly
         for the same;

(b)      to cause the  Mortgagor  to  continue to be  associated  with the other
         Participants  pursuant to the Mereenie  Operating  Agreement as a party
         thereto and to fulfil its several  obligations  thereunder or under the
         Sales  Contracts or concur in the  continuance of the same and for that
         purpose  to use any of the  funds  of  such  Participant  and for  that
         purpose to raise and use money on the  Charged  Property in priority to
         this charge;

(c)      to  receive  store  and/or  sell  what  otherwise  would  have been the
         Mortgagor's  share  of  products  derived  from or  produced  from  the
         Concession  (provided  such  products  are not the  subject  of a Sales
         Contract) on terms and conditions  similar to those which may have been
         obtained by any other  Participant  and the  exercise of such powers by
         the Receiver shall not be prevented or hindered by the terms hereof;

(d)      to let or lease any or all of the Charged Property;

(e)      to sell or concur in  selling  any of the  Charged  Property  either at
         public  auction or by private treaty and either for a lump sum or a sum
         payable by instalments or for a sum on account and a mortgage or charge
         for the balance,  in each case after giving to the  Mortgagor  and each
         Special  Chargee at least seven (7) days'  notice of his  intention  to
         sell  and  to  carry  any  such  sale  into  effect  by  conveying  and
         transferring  in the name and on behalf of the  Mortgagor  or otherwise
         and  the  Mortgagor  shall  execute  all  such  assurances,  deeds  and
         instruments  and do all  such  acts  and  things  whatsoever  as may be
         necessary  to vest the  Charged  Property  in the person or persons who
         purchase the same;

(f)      to execute all such contracts, deeds, transfers and other assurances in
         the name and on behalf of the  Mortgagor  for the  purpose of  carrying
         into  effect  any  of  the  powers  and  authorities  conferred  on the
         Enforcing Party as he may see fit;

(g)      to make any arrangement or compromise which he thinks expedient;  and

(h)      generally  to do or cause to be done such acts and things  representing
         the Charged Property  (without being responsible for any loss or damage
         which happens  thereby) as he may think  necessary and which could have
         been done or caused to be done by any  Receiver if he had the  absolute
         ownership of the Charged Property.

Any person paying money to or otherwise  dealing with the Enforcing  Party shall
not be  concerned to enquire  whether any event has  occurred to  authorise  the
Enforcing  Party to act and the  receipt  of any such  Enforcing  Party  for any
moneys arising under any of the powers aforesaid shall be a sufficient discharge
without obliging the persons paying the same to see to the application thereof.


<PAGE>

7.       The proceeds in  respect  of  the  Charged Property  of  the  Mortgagor
derived from the  exercise of the powers  referred to in Clause 6 hereof for the
sale thereof shall be applied:-

FIRSTLY:          in payment of any moneys having  priority to the charge hereby
                  created;

SECONDLY:         in  payment  of  all  costs,   charges  and  expenses  of  and
                  incidental to the appointment of the Receiver and the exercise
                  by the Enforcing Party of all  or any of  the powers aforesaid
                  including the reasonable remuneration of the Enforcing Party;

THIRDLY:          to the Operator the amount of any  Indebtedness  to the extent
                  that  the same has not  been  paid by  other  Participants  in
                  accordance  with the provisions of Clause 17.3 of the Mereenie
                  Operating  Agreement,  and to the  Participants  who have paid
                  their full  proportionate  share of any Indebtedness on behalf
                  of the Mortgagor in accordance  with the  provisions of Clause
                  17.3 of the Mereenie  Operating  Agreement such  proportionate
                  share of any Indebtedness so paid and not otherwise recovered;
                  and then

FOURTHLY:         all amounts (if any)  recovered in excess  of the sum required
                  to discharge the  Indebtedness  shall subject to proper claims
                  enforceable under other encumbrances be paid to the Mortgagor.

Save as  aforesaid  neither the  Non-Defaulting  Participants  nor the  Operator
(unless it be a  Participant  in default)  shall be under any  liability  to the
Enforcing Party for his remuneration costs, charges or expenses or otherwise.

8.       Claims  arising  from  the  priority  described  within  the  paragraph
"THIRDLY"  of Clause 7 hereof  shall as between such claims rank pari passu with
the result that if the amount  realised in any such action shall be insufficient
to discharge  all  Indebtedness  described  in such clause the amount  available
therefor  shall be  apportioned  among  the  claimants  in  proportion  to their
respective claims.

9.       The  charge  created  by  this  Deed  shall  be  deemed  a running  and
continuing  security  notwithstanding  any  settlement  on account of particular
Indebtedness  or any other matter or thing  whatsoever  and shall remain in full
force until a final discharge  thereof has been executed by the Operator and the
Non-Defaulting Participants.

Mortgagor  enforcement hereof shall also be subject to the provisions of Clauses
19.4.2(a), 19.4.2(b), 19.4.2(c), 18 and 28.8 of the Mereenie Operating Agreement
and in the  event of any  conflict  between  this Deed and a Deed in the form of
Annexure  "D" to the Mereenie  Operating  Agreement on the one hand and the said
Clauses of the Mereenie  Operating  Agreement on the other hand the latter shall
prevail.

11.      The Mortgagor and each Participant  shall from time to time execute and
deliver such further charges and other documents (including without limiting the
generality  of the  foregoing,  mortgages  or charges  collateral  hereto of its
interest  in all or some of the titles  constituting  the  Concession  in a form
registrable  as a legal mortgage or charge under the laws pursuant to which such
titles are  granted) as may be  reasonably  requested by any chargee in order to
confirm or effectuate the intent and purposes of this Deed. The Mortgagor  shall
forthwith  duly register or record this Deed and shall file or record such other
notice or documents relating thereto in such jurisdictions as may be required by
law to perfect the security hereby given.

12.      The Mortgagor hereby covenants with each of the other Participants that
it has full power to charge the Charged  Property  as  provided  herein and also
that, if default is made in payment of the Indebtedness or any part thereof,  it
shall be lawful for the Operator or other party or parties (as applicable having
regard to the provisions of Clauses 3.1 to 3.4 inclusive and 7 hereof), to enter
into and upon or receive and  thenceforth  quietly hold,  occupy,  and enjoy, or
take,  and have the  Charged  Property or any part  thereof,  without any lawful
interruption or disturbance by the Mortgagor and that, freed and discharged from
or otherwise by the Mortgagor  sufficiently  indemnified  against,  all estates,
encumbrances,  claims and demands whatever, other than those subject whereto the
Charge is expressly made.

other  Participants  to  execute  and  deliver  all such  assurances,  deeds and
instruments  and do all such acts and things  whatsoever  as may be necessary to
release  and  discharge  or to  substitute  by way of  additional  security  (as
appropriate) in respect to the first fixed charge hereby created the present and
future interest of the Mortgagor in:-

(a)      each Sales Contract to the extent necessary to accord with the interest
         of the  Mortgagor  from time to time under each such Sales  Contract as
         notified pursuant to the provisions thereof; and

(b)      the Concession to the  extent necessary to give  effect to the Mereenie
         Operating Agreement;

and to duly  register,  file or record all such  notices or  documents  relating
thereto in such jurisdictions as may be required by law to perfect such release,
discharge or substitution as aforesaid.

14.      All notices  required  to be given by or  pursuant  to  this Deed shall

provisions of Clause 27 of the Mereenie Operating Agreement.

                  Springs  Contract  except as provided in clauses  2.24,  2.25,
                  2.26 and 2.26A  hereof  and except for such gas as may be used
                  or  lost  in   drilling   development,   testing,   producing,
                  processing,  compression  and other similar  operations on the

                  accordance with good oilfield practice.

2.24     In the  event  that  from  time  to  time  all or any of the  Producers
         establish to the  reasonable  satisfaction  of the  Purchaser  that the
         reserves in the Gas Field exceed the quantity sufficient to enable each
         Producer to perform its future supply  obligations under this Agreement
         in Contract Years 1 to 20 inclusive (including  contingent  obligations
         under  clause 3.60  unless and until the  Purchaser  has agreed,  or an
         Independent  Expert has certified pursuant to clause 2.25(c) , that the

                           Mereenie Producers  have established their ability to
                           supply  Mereenie Gas in the contracted  quantities on
                           a continuous basis then  it may request the Purchaser
                           to review  its  requirements  in  respect  of  Excess

                           Reserves in calculating  Excess Proven Reserves below
                           the aggregate of:

                           (A)      200%  of the Annual Minimum Quantities still
                                    to be supplied  pursuant to  this Agreement;
                                    and

                  offered that  quantity  for sale to the  Purchaser at the same
                  price (including  provisions for escalation as to price) as it
                  would be prepared to sell the same to any other party.

         (b)      If the Purchaser  fails or declines to accept the offer within
                  such 30 days, the Producer shall be at liberty for a period of
                  180 days  thereafter to sell that quantity to another party at
                  a price  not less than  that  price or on terms or  conditions
                  conferring  economic benefits on the Producer over the life of
                  the contract at least equivalent to that price.

         (c)      In the event of the  Purchaser  accepting the offer in respect
                  of price the  Purchaser  and the Producer  shall  negotiate in
                  good faith the terms and conditions of a purchase contract.

         (d)      In the event that a contract is not executed by the expiration
                  of 60 days after acceptance of price (or such longer period as
                  the parties  shall agree upon) further  negotiations  shall be
                  abandoned and the Producer shall be at liberty for a period of
                  180 days  thereafter to sell that quantity to another party at
                  a price  not less than  that  price or on terms or  conditions
                  conferring  economic benefits on the Producer over the life of
                  the contract at least equivalent to that price.

         (e)      The Purchaser covenants to keep confidential any offer made by
                  any Producer.

2.26A.   (a)      Notwithstanding the provisions of clauses 2.23, 2.24, 2.25 and
                  2.26 hereof  in the event  that the  Mereenie Producers  shall
                  have given notice to the Purchaser as  contemplated  in clause
                  3.64  hereof  of  an   anticipated   failure  in  delivery  of
                  contracted  quantities pursuant to the Mereenie Agreement then
                  in the  absence  of  receipt of a  Shortfall  Notice  from the
                  Purchaser each of the Producers  shall be at liberty to supply
                  to the  Purchaser  on behalf  of the  Mereenie  Producers  its
                  Ownership  Percentage of the Gas which the Mereenie  Producers
                  would  otherwise  fail to deliver;  and in so doing a Producer
                  shall not be in breach  of any of the  provisions  of the said
                  clauses 2.23, 2.24, 2.25 and 2.26 hereof.

         (b)      Any such supply of Gas by a Producer on behalf of the Mereenie

                  be  entitled  to any  payment  from the  Purchaser  in respect
                  thereof  (the  intention  being that the  Producers  will seek
                  payment of an agreed amount from the Mereenie Producers).

2.27     (a)      The Purchaser shall not sell or offer to sell Gas delivered to
                  it pursuant to this Agreement  except  to the Consumers or the

         (b)      The  Purchaser  shall so far as it lies within its  reasonable
                  capacity  ensure  that Gas  delivered  to it  pursuant to this
                  Agreement  is not sold by the  Pipeline  Operator to any party
                  other than a Consumer,  or as provided for in clause 2.28, and
                  is not sold by any  Consumer  to any party for the  purpose of
                  resale or reticulation to the public.

                           remaining  under this  Agreement  is in excess of the
                           quantity of Gas  required by the  Purchaser  in those
                           Contract  Years ("the Excess Take or Pay  Quantity");

                           Quantity by 125% of that reduction.

         (c)      In the event that the Producers do not jointly exercise either
                  of the options provided for in clause 2.28 (b) within the time

                  the Purchaser.

         (d)      If the Purchaser  has made a  confirmation  pursuant to clause
                  3.52 then the  provisions of this clause 2.28 shall not  apply
                  in respect of that Gas.

2.30     Pipeline

2.31     The Purchaser shall at no cost to the Producers  complete all necessary
         arrangements to cause to be constructed and  commissioned  the Pipeline

         Purchaser  shall give  notice to the  Producers  jointly of the precise
         location at the existing  plant or some other  appropriate  point in or
         adjacent  to the  Petroleum  Lease at which  the  inlet  flange  of the
         Pipeline will be constructed.

2.40     Gas Delivery System

2.41     Forthwith upon receipt of the notice from the Purchaser provided for in
         clause 2.32 the Producers jointly undertake that they will proceed with
         due diligence to render the Gas Field  suitable for routine  production
         and  install  the Gas  Delivery  System in such manner as to ensure the
         continuous supply of Gas in accordance with this Agreement.

2.51     (a)      Subject to the provisions of this clause the Producers jointly
                  undertake that they will from  time to time during the term of
                  this Agreement  duly carry  out  in  accordance with  good oil
                  field practice  and  in  a  cost-effective  manner  such  work
                  ("Development Work")  as is necessary  for the  development of
                  the Gas Field to ensure that the Gas Delivery System will have
                  the  delivery  capacity  and will be able  to  deliver  to the
                  Purchaser on  any  Day during the  term of this  Agreement the
                  maximum  quantity  of  Gas  which  the  Purchaser  is entitled
                  pursuant to  clause 3.23  to nominate for delivery on any Day,
                  namely the Daily  Peak  Demand  Quantity  but  ignoring in the
                  absence of a Schedule A Variation Notice any possible increase
                  in such Daily Peak Demand Quantity which may result from such
                  a Notice.

         (b)      Development   Work  for  the  purpose  of  the  definition  in
                  paragraph  (a) shall  subject  however  to the  provisions  of

                  following:

                  (i)      rendering   the   Gas  Field   suitable  for  routine
                           production,

                  (ii)     installing   the   Gas   Delivery  System   and   any
                           modifications and expansions thereof,

                  (iii)    drilling of Additional Wells;


<PAGE>

                  (iv)     completing  all   successful   Additional  Wells  and
                           connecting same to the Gas Delivery System; and

                  (v)      further  work  as  may  be  required by the Purchaser
                           pursuant to clause 2.56.

         (c)      Without  prejudice  to  the  provisions  of  clause  2.53  the
                  Producers  jointly  undertake that they will from time to time
                  prepare  and  deliver  to the  Purchaser  plans and  revisions
                  thereof for the carrying out of Development Work ("Development
                  Plans")  together  with budgets and cost  estimates in respect
                  thereof  itemised  in  reasonable  detail so as to permit  the
                  Purchaser to review the same PROVIDED  ALWAYS that neither the
                  opportunity  for such review nor a failure by the Purchaser to
                  respond to the Producers in respect thereof shall be deemed to
                  estop the Purchaser  from  exercising  its rights under clause
                  2.57.

2.52     (a)      The Gas Delivery System  shall  have  sufficient  capacity  in
                  accordance  with good oil field  practice  to  deliver  to the
                  Purchaser  the  Daily  Peak  Demand  Quantity  on any  Day but
                  subject  always to clause  3.22(a) and ignoring in the absence
                  of a Schedule A Variation Notice any possible increase in such
                  Daily  Peak  Demand  Quantity  which  may  result  from such a
                  Notice.

         (b)      The Purchaser,  having  particular regard to the fact that Gas
                  is to be  supplied  under this  Agreement  for the  purpose of
                  generating electric power for public consumption, acknowledges
                  the  need  for the Gas  Delivery  System  to  have  excess  or
                  redundant capacity.

         (c)      The type, size, location and all other matters relevant to the
                  Gas Delivery  System shall be as  determined  by the Producers
                  jointly after consultation with the Purchaser.

2.53     (a)      The Producers  jointly  shall  notify  the  Purchaser  of  the
                  proposed  location,  depth and  cost of each  Additional  Well
                  proposed by them as Development Work.

         (b)      With  respect  to not  more  than  nine (9)  Additional  Wells
                  proposed   by  the   Producers   the  same  shall   constitute
                  Development  Work to the extent only to which they are in each
                  case  planned,  drilled  and, if  appropriate,  completed  and
                  connected to the Gas Delivery  System in accordance  with good
                  oil field practice and in a cost-effective  manner and subject
                  to  such  other   paragraphs   of  this  clause  as  shall  be
                  applicable.

         (c)      In the case of each  of the first  four (4)  Additional  Wells
                  proposed by the Producers  (or  such  lesser  number  as  they
                  propose):

                  (i)      Each Well shall  constitute  Development  Work unless
                           the Purchaser  notifies the Producers  jointly within
                           30 days of receipt of the Producers' proposal that it
                           does not accept the  proposal in respect of that Well
                           as  Development  Work  based on  expert  opinion  and
                           provides details of the reasons for that opinion.


<PAGE>

                  (ii)     If the  Purchaser  so  notifies  them  the  Producers
                           jointly may either:

                           (A)      before proceeding with the proposal have the
                                    question   determined   by  an   Independent
                                    Expert,   who  shall,   if   supplied   with
                                    sufficient data for that purpose, propose an
                                    alternative  location for any proposed  Well
                                    which he rejects as Development Work, or

                           (B)      proceed  with  the  proposal  without  first
                                    having the question  determined  but without
                                    prejudice  to their  right to claim the same
                                    as Development  Work pursuant to clause 2.51
                                    and  without  prejudice  to the  Purchaser's
                                    right to dispute that such  Additional  Well
                                    constituted  Development  Work  and in  such
                                    case to have the  question  referred ex post
                                    facto to an Independent  Expert and (if such
                                    Independent   Expert   confirms   that  such
                                    Additional  Well did constitute  Development
                                    Work) without prejudice to clause 2.57.

         (d)      In the case of each of the next five (5) Additional Wells  (if
                  any) so proposed by the Producers:

                  (i)      No Additional Well shall constitute  Development Work
                           unless the  Purchaser  accepts the  proposal for that
                           Well  as  Development Work  or unless  an Independent
                           Expert  determines   that   the   proposal   (or   an
                           alternative  location  if  appropriate)   constitutes
                           Development Work.

                  (ii)     If the  Purchaser  does not accept a proposal  by the
                           Producers  within 30 days of receipt of the  proposal
                           under  paragraph  (a)  an  Independent  Expert  shall
                           determine  the  question  subject  to  the  following
                           provisos:

                           (A)      in the  case  of  all  five  (5)  Additional
                                    Wells,  he shall not  determine the question
                                    in favour of the  Producers  unless he first
                                    satisfies  himself that the Proven  Reserves
                                    remaining   in  the  Gas  Field  exceed  the
                                    Warranted Quantities,

                           (B)      in  the  case  of  each  of  the  7th to 9th
                                    Additional Wells, he shall not determine the
                                    question in favour of the  Producers  unless
                                    he also first satisfies himself that further
                                    Development Work is economically justifiable
                                    to the Purchaser, and

                           (C)      where the Independent Expert is satisfied on
                                    each   of  the   matters   referred   to  in
                                    subparagraphs (A) and (B) above he shall, if
                                    supplied  with   sufficient  data  for  that
                                    purpose, propose an alternative location for
                                    any  proposed  Well  which  he  nevertheless
                                    rejects as Development Work.

                  (iii)    For  the  purpose  of  determining   whether  further
                           Development  Work is economically  justifiable to the
                           Purchaser it is agreed that:-

                           A.       further Development Work shall not be deemed
                                    economically  justifiable if at the relevant
                                    time  the  delivered  cost of Gas in  Darwin
                                    (comprising  the  prevailing  Contract Price
                                    for Gas, plus Recovery  Payments  calculated
                                    as if the costs of the proposed  Development
                                    Work  had  been  incurred,  plus the cost of
                                    transportation  of Gas to Darwin through the
                                    Pipeline) would exceed the deemed  delivered
                                    cost of diesel  fuel in Darwin (as  provided
                                    in   paragraph   (iii)   below)   having  an
                                    equivalent energy content; and

                           B.       further  Development  Work  shall be  deemed
                                    economically  justifiable if at the relevant
                                    time the aforesaid  delivered cost of Gas in
                                    Darwin is equal to or less  than the  deemed
                                    delivered  cost of  diesel  fuel  in  Darwin
                                    having an equivalent energy content.

         (iv)     For the purpose of the preceding subparagraph (iii) the deemed
                  delivered  cost of diesel fuel in Darwin shall be whichever is
                  the higher of:-

                  (a)      the then prevailing  delivered cost of diesel fuel in
                           Darwin and

                  (b)      $460 per tonne (being the current  delivered  cost of
                           diesel   fuel  in   Darwin),   escalated   since  the
                           Development  Date to the relevant  time in proportion
                           to movements in the CPI.

2.54     (a)      The  Producers  jointly  shall  from  time to time  notify the
                  Purchaser of Additional  Wells,  in addition to the Additional
                  Wells referred to in clause 2.53, which the Producers  jointly
                  and reasonably  determine are required to be drilled to ensure
                  that the Gas Delivery System has and will continue to have the
                  delivery capacity and will be able to deliver to the Purchaser
                  on any Day the Daily Peak Demand Quantity.

         (b)      The  drilling  of such  Additional  Wells  shall  form part of
                  Development  Work if the  Producers  and the  Purchaser  shall
                  mutually agree upon the location and other matters relevant to
                  the drilling of such Additional Wells.

         (c)      In the event that the Purchaser  fails within 60 days to agree
                  to the  drilling of any  Additional  Well in  accordance  with
                  paragraph (b) the Producers  shall not be obliged to drill any
                  such Additional Well or carry out such work and the provisions
                  of clause 2.55 shall at the request of the Producers apply.


<PAGE>

2.55     After the  expiration  of one (1) month after any  proposed  Additional
         Well has been  rejected as  Development  Work under  clause 2.53 or any
         disagreement  occurring  as referred to in clause 2.54 and at intervals
         of not less than two years  thereafter  the Producers  jointly may from
         time to time by notice to the Purchaser elect to vary either  downwards
         or upwards the Annual Minimum Quantity by a percentage specified by the
         Producers   jointly  any  such   variation  to  take  effect  from  the
         commencement of the next Contract Year PROVIDED HOWEVER as follows:

         (a)      No  increase  under  this  clause  shall  have the  effect  of
                  increasing  the  relevant   quantities  above  the  quantities
                  applying  for  the  relevant  Contract  Year  at the  date  of
                  execution of this Agreement;

         (b)      No decrease  under this clause shall have effect to the extent
                  that it  shall  diminish  the  Purchaser's  entitlement  to be
                  supplied with the Warranted Quantities or such lesser quantity
                  as may be determined under paragraph (c);

         (c)      In the event that an  Independent  Expert  certifies  that the
                  failure  of the  Purchaser  to  agree to the  drilling  of any
                  Additional  Well under clause 2.53 or clause 2.54 is the cause
                  of  the  reduction  in a  Producer's  ability  to  supply  its
                  Ownership  Percentage  of  the  Warranted  Quantities  then  a
                  decrease  under this  clause may take  effect to the extent of
                  such reduction.

2.56     (a)      Without diminishing  the extent of the  Producers' obligations
                  under clause 2.51,  in the event that  the Purchaser is of the
                  opinion that the Proven Reserves  and  production capacity are
                  insufficient  for the purpose of ensuring  that  each Producer
                  can perform its future supply obligations under this Agreement
                  (including contingent  obligations under clause 3.60) then the
                  Purchaser may by notice  to the Producers jointly require them
                  to carry out as provided  in  this  clause 2.50  such  further
                  Development Work  as may  in the  opinion  of the Purchaser be
                  necessary.

         (b)      In the event that the Producers jointly dispute the opinion of
                  the Purchaser  referred to in paragraph (a) the Producers will
                  not be  required  to carry out as provided in this clause 2.50
                  any  such  further   Development  Work  unless  and  until  an
                  Independent  Expert  certifies  that such further  Development
                  Work as he specifies in the certificate is necessary.

         (c)      Upon  receipt of a  certificate  by an  Independent  Expert as
                  provided in paragraph (b) the Producers  shall  promptly carry
                  out as provided  in this  clause 2.50 the further  Development
                  Work certified therein.

2.57     (a)      Following  completion  of each  item of  Development Work  the
                  Producers  jointly shall  promptly  provide to the Purchaser a
                  full accounting  (supported by relevant technical  information
                  and copies of or access to invoices, orders, contracts and the
                  like) of the costs thereof in order to permit the Purchaser to
                  review and/or audit the same.


<PAGE>

         (b)      If the Purchaser is of the bona fide opinion, having regard to
                  inspections under clause 2.42 and to the information  provided
                  under paragraph (a) of this clause,  that any Development Work
                  has not been  carried  out in  accordance  with good  oilfield
                  practise  or  in a  cost-effective  manner  having  regard  to
                  circumstances  prevailing  at the time  then it  shall  within
                  sixty (60) days of receipt of the said information communicate
                  such opinion to the  Producers  jointly and, in the absence of
                  agreement  being  reached  between the parties,  may refer the
                  question to an Independent Expert.

         (c)      To the extent,  if any, to which the  Producers  jointly shall
                  agree or an Independent  Expert shall determine that any costs
                  of Development  Work have been incurred as a result of failure
                  to  observe  good  oilfield   practise  or  failure  to  cause
                  Development Work to be carried out in a cost-effective  manner
                  having  regard to the  circumstances  prevailing  at the time,
                  such costs shall not constitute Development Expenditure.

2.58     Nothing herein  contained  shall be deemed  to prevent the Producers at
         their own risk and expense undertaking any work on the Gas Field.

2.60     Independent Expert

         (a)      For the purposes of this Agreement an Independent Expert shall
                  be an expert in the field in question agreed by the parties or
                  in the absence of agreement determined by the Chairman for the
                  time being of the Australian Petroleum Exploration Association
                  (or its successor) or his nominee on the application of either
                  party with notice to the other.

         (b)      An Independent Expert shall  act  as an  expert  and not as an
                  arbitrator.

         (c)      An  Independent  Expert  shall  furnish  with  all  reasonable
                  expedition a  certificate  as to his decision on any matter in
                  dispute  between the parties and such decision  shall be final
                  and binding.

         (d)      Each party shall have the right to make written submissions to
                  an  Independent  Expert,  to  receive  copies of each  other's
                  submissions  and to reply thereto,  such right to be exercised
                  promptly.

         (e)      The costs of an  Independent  Expert  shall be borne as to one
                  half  by the  Purchaser  and as to the  remaining  half by the
                  Producers  in   proportion  to  their   respective   Ownership
                  Percentages.

                  (i)      its  Ownership  Percentage  of  the  Monthly  Minimum
                           Quantity of Gas;

                  (ii)     its Ownership  Percentage of such additional Gas (not
                           being Gas committed to other  contracts in any manner
                           permitted by the terms  hereof) as the  Purchaser may
                           require under clauses 3.22 and 3.24, and

                  (iii) its share of Default Gas due under clause 3.47,

                  and upon and subject to the terms and conditions  contained in
                  this  Agreement  the  Purchaser  agrees to  purchase  and take

         (b)      In each Month of each Contract Year the Purchaser's obligation
                  to purchase the Monthly Minimum  Quantity for that Month shall
                  be reduced by the aggregate of:

                  (i)      any  portion  of the  Monthly  Minimum  Quantity  not
                           tendered for delivery in that Month whether by reason
                           of permitted  interruption pursuant to clause 3.33 or
                           pursuant to clause 3.66 or otherwise;

                  (ii)     any portion of the Monthly Minimum Quantity which the

                           (A)      by Force Majeure affecting the Producers; or

                           (B)      by Pipeline Force Majeure.

                  (iii)    all excess quantities which the Purchaser is entitled
                           to credit  against the Monthly  Minimum  Quantity for
                           that  Month  pursuant  to clause  3.25  (that is, not
                           exceeding one half of the Monthly Minimum Quantity).

         (c)      If in any  Month  the  Purchaser  fails  to take  the  Monthly
                  Minimum Quantity  reduced if applicable  pursuant to paragraph
                  (b)  the  Purchaser  shall  pay  the  Contract  Price  for the
                  quantity not so taken as if the same had been delivered during
                  that Month  subject  always to refund if the Gas Field becomes
                  depleted in accordance with clause 4.30.

3.22     Subject to clause  3.24 and to any  interruptions  under  clause  3.33,
         throughout the term of this Agreement from the Date of Initial Delivery
         Gas  shall  be  delivered  to the  Purchaser  on each  Day at the  rate
         required by the Purchaser up to:

         (a)      the Daily Peak Demand Quantity on not more than 50 Days in any

                  nominate:

                  (i)      the rate at which  delivery of Gas is  required  (not
                           exceeding the quantities provided for in clause 3.22)
                           and not in any event  exceeding the quantity which on
                           that Day the  Purchaser is entitled to have  accepted
                           for  transmission  through the Pipeline and which the
                           Pipeline is capable of accepting on that Day; and

                  (ii)     the Day and hour  when  such  nomination  shall  take
                           effect  not being  less than four hours from the time
                           of nomination,

                  the parties shall agree on more frequent nomination procedures
                  and shorter nomination times under paragraph (ii) in the event
                  that the Gas  Delivery  System is  automated  or for any other
                  reason is able to accommodate such changes.

         (b)      The total  quantity  of Gas which  would be  delivered  by all
                  Producers  during  any Day if  delivery  was to  occur  at the
                  nominated rate or rates shall constitute Obligation Gas.

         (c)      All  nominations  may  be  made  by  telephone  but  shall  be
                  confirmed by written notification within 24 hours.

                  Purchaser's most recent nomination until superseded by a later
                  nomination.

         (e)      The  Purchaser  shall  prior  to  the  commencement  of  every
                  Contract Year give notice to the Producers jointly of:

                  (i)      Its likely  annual requirements  of Gas  for the next
                           five Contract Years;

                  (ii)     Its likely Monthly requirements  of Gas for the  next
                           twelve Months.

         (f)      The Purchaser  shall prior to the  commencement  of each Month
                  give  notice to the  Producers  jointly  of its  likely  daily
                  requirements of Gas for that Month.


<PAGE>

3.24     If on any Day or Days the Purchaser  requires  amounts of Gas at a rate
         in excess of the Daily Peak  Demand  Quantity or (if the number of Days
         upon which the Daily Peak Demand  Quantity  has been  nominated  in any
         Contract Year is equal to or more than 50) the Daily  Maximum  Quantity
         it may request by notice given to the Producers jointly that deliveries
         be made at such  rate and each  Producer  will  deliver  its  Ownership
         Percentage of Gas at such rate  PROVIDED  HOWEVER that if a Producer is
         unable to do so having  regard to the capacity of the then existing Gas
         Delivery  System it shall notify such  inability to the  Purchaser  and
         shall  not be  obliged  to  deliver  Gas  in  excess  of its  Ownership
         Percentage  of the Daily  Peak  Demand  Quantity  or the Daily  Maximum
         Quantity as the case may be.

3.25     (a)      In the event  that  in  any  Month of any  Contract  Year  the
                  Purchaser  purchases  and takes  Gas in excess of the  Monthly
                  Minimum Quantity less any increase  therein effected  pursuant
                  to a Shortfall  Notice plus all Make-up Gas  accumulated up to
                  and including that Month, such excess shall be carried forward
                  and credited against the Purchaser's subsequent commitments to
                  purchase and take the Monthly Minimum Quantity.

         (b)      No  credit   pursuant  to  paragraph   (a)  shall  reduce  the
                  Purchaser's commitments to purchase and take below one half of
                  the  Monthly  Minimum   Quantity  in  any  Month.  Any  credit
                  remaining  after any  reduction to such level shall be carried
                  forward as a credit in a subsequent month or months.

         (c)      If by the  application  of a credit  pursuant to paragraph (a)
                  the  Purchaser in any Month shall  purchase and take less than
                  the Monthly  Minimum  Quantity in that Month then the quantity
                  of  Gas  equivalent  to the  difference  between  the  Monthly
                  Minimum  Quantity  in that  Month  and the  quantity  actually
                  purchased  and taken by the  Purchaser  in that Month shall at
                  the option of the  Producers  jointly be debited  against  the
                  Dedicated Quantity.

3.26     The Purchaser  shall use  reasonable  endeavours to ensure that on each
         Day during the term of this  Agreement it purchases  from each Producer
         that Producer's  Ownership  Percentage of 80% of the Purchaser's Excess
         Requirements of Gas on that Day.

         For purposes of this clause the Purchaser's  Excess  Requirement of Gas
         means in respect of any Day so much of the Purchaser's  requirements of
         Gas on that Day as exceeds the aggregate of the Daily Minimum  Quantity
         and the Daily  Minimum  Quantity as  applicable  for that Day under the
         Mereenie Agreement, but does not exceed 125% of that aggregate.

3.30     Continuity of Supply

3.31     It is an  essential  term  of  this  Agreement  that  supply  of Gas in
         accordance   with  this  Agreement   shall  commence  at  the  time  of
         commissioning of the Pipeline as notified pursuant to clause 2.30.


<PAGE>

3.32     Subject to the terms of this Agreement each Producer undertakes that it
         will  throughout  the term of this  Agreement  maintain  continuity  of
         supply to the  Purchaser  at the inlet  flange of the  Pipeline  of its
         Ownership  Percentage  of  the  Purchaser's   requirements  of  Gas  in
         accordance with this Agreement.

3.33     The  Producers  jointly may  nevertheless  interrupt  supply to perform
         reservoir  tests and  evaluations in accordance with and subject to the
         following limitations and procedures:

         (a)      Each interruption shall not exceed the following durations and
                  frequencies:

         Contract Years                Maximum                   Maximum
         Years                         Duration                  Frequency
         --------------------------------------------------------------------

         1 to 5 inclusive              120 hours                 Quarterly
         6 until contract              120 hours                 Half Yearly
         expiration

         (b)      The dates and times chosen for testing  shall be arranged with
                  the  Purchaser  and with the  Pipeline  Operator  and with the
                  Mereenie  Producers  as far as  possible  in advance and shall
                  always unless otherwise agreed  correspond with periods of low
                  demand for electricity and shall not unless  otherwise  agreed
                  correspond  with  periods of  interruption  under the Mereenie
                  Agreement.

         (c)      The   Producers   jointly   shall   be   allowed    additional
                  interruptions  for  unforeseen  and  unscheduled  events  (not
                  constituting   Force   Majeure)  not   exceeding  a  total  of
                  forty-eight (48) hours in each year.

         (d)      In the event of any  interruption in transmission  through the
                  Pipeline or cessation of electricity  production at any of the
                  power stations the Purchaser may notify the Producers  jointly
                  and  the  Producers   jointly  undertake  to  use  their  best
                  endeavours to carry out testing during such  interruptions  in
                  lieu of those provided for in this clause.

3.34     Whenever a Producer  becomes  aware that it cannot or may become unable
         to maintain  continuity of supply in accordance  with this Agreement it
         shall forthwith advise the Purchaser and the Mereenie Producers of that
         fact so as to enable the  Purchaser  at the earliest  possible  time to
         make arrangements for purchase of Gas from the Mereenie Producers.

3.40     Failure to Supply

3.41     In the event that for any reason other than Force  Majeure or permitted
         interruptions  under  clause  3.33 a  Producer  fails  to  deliver  its
         Ownership  Percentage of  Obligation  Gas on any Day then that Producer
         ("the  Defaulting  Producer")  shall be deemed to have made  default in
         delivery of the quantity of Gas equivalent to its Ownership  Percentage
         of the quantity of Obligation Gas on that Day minus the quantity of Gas
         actually  delivered on that Day by the  Defaulting  Producer  ("Default
         Gas") and the  following  provisions  of this  clause  3.40 shall apply
         PROVIDED THAT the Defaulting  Producer shall be deemed not to have made
         default in delivery as aforesaid if:

         (a)      (i)      such failure does not exceed two continuous Days;

                  (ii)     the  Defaulting  Producer  delivers not less than its
                           Ownership Percentage of the Daily Minimum Quantity on
                           that Day; and

                  (iii)    the Defaulting Producer delivers within the following
                           two days an additional  quantity of Gas equivalent to
                           the quantity of Default Gas.

         or

         (b)      the Defaulting  Producer  delivers or procures the delivery of
                  Gas or natural gas with  specifications to which the Purchaser
                  has agreed from a source other than from the  Petroleum  Lease
                  to the Field  Delivery  Station  or any other  field  delivery
                  station  linked to the  Pipeline and the  Defaulting  Producer
                  shall be duly paid the Contract Price for any such gas.

         or

         (c)      clause 3.66 operates  to relieve the  Defaulting Producer of a
                  default.

3.42     Upon a Defaulting  Producer making default in delivery as aforesaid the
         Defaulting  Producer  shall  have  the  opportunity  to  supply  to the
         Consumers at their various points of consumption other energy in a form
         compatible  with the power  generation  equipment of NTEC and having an
         energy  content in whole or in part  equivalent to the Default Gas. Any
         such  other  energy  shall  be  supplied  at the  cost  and risk of the
         Defaulting Producer without charge to the Consumers,  and the Purchaser
         shall duly pay for such other energy so supplied the Contract Price for
         Gas having an energy content equivalent thereto.

3.43     If the  Defaulting  Producer  shall have made  default in  delivery  as
         aforesaid and if that Producer shall not have delivered other energy in
         exercise of its right under  clause 3.42 then the  Defaulting  Producer
         shall  subject  to  clause  3.43A  promptly  pay and  reimburse  to the
         Purchaser by way of liquidated damages the amount (if any) by which the
         Delivered  Cost of Substitute  Energy  exceeds what would have been the
         Contract  Price of an  amount  of  Obligation  Gas  deliverable  by the
         Defaulting Producer having an energy value equivalent to the Substitute
         Energy but not  exceeding  the energy value of the Default Gas provided
         that such Substitute  Energy shall be obtained as far as practicable in
         the circumstances at the least cost.


<PAGE>

         For the purpose of this clause:

         (a)      The term  "Delivered  Cost" shall mean the unit cost  actually
                  incurred by NTEC or which would have been incurred by NTEC had
                  it been the  Consumer in relation to the  relevant  Substitute
                  Energy;  the cost  actually  incurred  by any  other  Consumer
                  (whether greater or smaller) shall be irrelevant;

         (b)      The term "Substitute  Energy" shall mean the total quantity of
                  energy  actually  consumed by all  Consumers at their  various
                  points of  consumption  for the purpose of  maintaining  their
                  power  generation  or  other  operations  as a  result  of the
                  Defaulting   Producer  having  made  default  in  delivery  as
                  aforesaid.

         (c)      If any Substitute  Energy is held in stock by the Consumers it
                  shall be costed on a  replacement  basis  from the  Consumers'
                  inventory at the relevant point of consumption.

3.43A    Where on any Day the amount of Obligation Gas exceeds the Daily Maximum
         Quantity (the difference being hereinafter  called "the Excess Amount")
         then the Defaulting  Producer's obligation to pay liquidated damages in
         regard to such Excess Amount under clause 3.43 shall be reduced by 90%.

3.44     The Purchaser  shall at the request of any Producer permit a registered
         company  auditor  nominated by that  Producer to have access to such of
         the books and records of the Purchaser as may be necessary to check any
         claims by the Purchaser pursuant to clause 3.43.

3.45     Save as provided in this clause 3.40 no Producer shall be liable to the
         Purchaser or any of the Consumers  (and the Purchaser  shall  indemnify
         and keep  indemnified each Producer against any such liability) for any
         other or  consequential  loss or damage resulting from the failure of a
         Producer  to supply its  Ownership  Percentage  of any  Obligation  Gas
         during  the  term of the  agreement  including  inability  to  generate
         electricity loss of electricity supply or loss of profits.  No Producer
         shall  in any  event  be  liable  for  any  liability  incurred  by the
         Purchaser under the Gas Supply Agreements.

3.46     It shall be no defence to any action by the  Purchaser  for recovery of
         damages  pursuant  to  clause  3.43 that the  Purchaser  shall not have
         personally  incurred  the  cost of the  Substitute  Energy  where  such
         Substitute Energy has been acquired by the Consumers or any of them.

3.47     If a Producer  becomes a  Defaulting  Producer  under this  clause each
         other  Producer  shall be obliged to deliver  each Day on the terms and
         conditions  herein  contained a quantity of Gas equal to the proportion
         of Default Gas which its  Ownership  Percentage  bears to the aggregate
         Ownership  Percentages  of all  Producers  other  than  the  Defaulting
         Producer.

3.50     The Final Contract Years

3.51     A  Producer  ("the  Notifying  Producer")  may at any time prior to 1st
         January in the 20th Contract Year give notice to the Purchaser  that it
         desires to sell to a third  party  natural gas from the Gas Field which
         but for this clause it would be required to sell in the Contract  Years
         numbered 21 to 26 inclusive ("the Final Contract Years").

3.52     Except in Contract  Years 1 to 10 inclusive  (during  which period this
         clause 3.52 shall not apply) the  Purchaser  may after  receipt of such
         notice give notice to the Notifying  Producer  affirming this Agreement
         in respect of the Final  Contract  Years,  in which case this Agreement
         (so far as it is a  separate  agreement  with the  Notifying  Producer)
         shall continue in full force and effect  according to its terms and the
         notice given pursuant to Clause 3.51 shall be of no force or effect.

3.53     Forthwith upon receipt of any notice from a Notifying Producer given in
         Contract  Years 1 to 10 pursuant to clause 3.51,  or in any  subsequent
         Contract  Year if the  Purchaser  fails to give  notice to a  Notifying
         Producer  pursuant to Clause 3.52 within sixty (60) days after  receipt
         of that Producer's notice under Clause 3.51, then:-

         (a)      The Notifying Producer shall have no obligation to deliver any
                  Gas in the Final  Contract  Years and all  references  in this
                  Agreement  to  Annual  Minimum  Quantities,   Monthly  Minimum
                  Quantities  and the like  shall in  respect  of the  Notifying
                  Producer be read down accordingly

         (b)      the Notifying Producer may sell to a third party the Gas which
                  it is no longer  obliged to deliver  to the  Purchaser  in the
                  Final Contract Years

         (c)      the Dedicated Quantity  shall  be  reduced  by  the  Notifying
                  Producer's Ownership Percentage of 50 PJ, and

         (d)      in all other respects  this  Agreement  shall continue in full
                  force and effect.

         (e)      The Purchaser  may by notice to each  Producer  other than the
                  Notifying  Producer amend this Agreement (so far as it relates
                  to each such other  Producer)  in the same  respects  (mutatis
                  mutandis)  as provided in  paragraphs  (a) and (c) above,  and
                  paragraphs  (b)  and  (d)  above  shall  also  apply  (mutatis
                  mutandis) in respect of each such other Producer.

3.60     Failure of Delivery under the Mereenie Agreement

3.61     The  Producers,  having  regard to the fact that  natural  gas is to be
         supplied under both this  Agreement and the Mereenie  Agreement for the
         purpose of generating  electric power for public  consumption,  jointly
         acknowledge that the Purchaser requires  continuous delivery of the Gas
         the subject of each such Agreement according to their respective terms.


<PAGE>

3.62     If the Mereenie Agreement shall at any time be terminated by either the
         Purchaser or the Mereenie  Producers then the Purchaser may give notice
         to the Producers  jointly of such  termination (a "Schedule A Variation
         Notice") which shall specify that the Purchaser  requires each Producer
         to supply to the Purchaser upon and subject to the terms and conditions
         contained in this  Agreement its  Ownership  Percentage of the whole or
         any part of the  natural gas to which the  Purchaser  would have become
         entitled to delivery  under the Mereenie  Agreement,  and in particular
         shall specify:-

         (a)      in Part A thereof in respect of each whole remaining  Contract
                  Year an  amended  Annual  Minimum  Quantity  being the  Annual
                  Minimum  Quantity  specified  in Schedule A  increased  by the
                  whole  or any part of the  relevant  Annual  Minimum  Quantity
                  specified  in Schedule A to the  Mereenie  Agreement  for that
                  Contract Year and;

         (b)      in Part B thereof in respect of each remaining  whole Month of
                  the  Contract  Year  current  at the time of such  notice,  an
                  amended  Monthly  Minimum  Quantity being the Monthly  Minimum
                  Quantity  applicable  under this  Agreement  increased  by the
                  whole or any part of the  relevant  Monthly  Minimum  Quantity
                  applicable under the Mereenie Agreement; and

         (c)      in Part C thereof,  in respect of the period to the end of the
                  then current  Month,  the amount of  additional  Gas which the
                  Purchaser  requires to be delivered on a daily basis until the
                  end of such Month.

3.63     As from the date of receipt by  the Producers of a Schedule A Variation
         Notice:-

         (a)      Schedule A shall  forthwith be varied in the manner  specified
                  in Part A of such Notice with effect from the  commencement of
                  the next succeeding Contract Year;

         (b)      the Monthly  Minimum  Quantity  applicable for each succeeding
                  Month of the current  Contract Year shall be forthwith  varied
                  in the manner  specified  in Part B of such Notice with effect
                  from the commencement of the next succeeding Month, and

         (c)      the Daily  Minimum  Quantity of Gas for each  remaining Day of
                  the current  Month shall be increased in the manner  specified
                  in  Part C of the  said  Notice  with  effect  from  the  next
                  succeeding day

         but subject always to clauses 3.66 and 3.67.

3.64     If from  time to time or at any time  during  the term of the  Mereenie
         Agreement the Mereenie Producers fail to deliver contracted  quantities
         of  Mereenie  Gas or give  notice to the  Purchaser  of an  anticipated
         failure  in  delivery  of  contracted  quantities,  then  provided  the
         Purchaser  has not in respect of such  failure  delivered  a Schedule A
         Variation Notice the Purchaser may give notice to the Producers jointly
         under this Clause ("a Shortfall Notice") which shall specify:


<PAGE>

         (a)      the nature of the  delivery  failure  or  anticipated  failure
                  under the Mereenie Agreement;

         (b)      the  aggregate  quantity of Gas which the  Purchaser  requires
                  each Day to be delivered by the Producers  upon and subject to
                  the  terms  and  conditions  contained  in this  Agreement  in
                  substitution for Mereenie Gas ("Shortfall Gas") and

         (c)      the period during which Shortfall Gas is likely to be required
                  by the Purchaser ("Shortfall Period").

3.65     Upon receipt of a Shortfall  Notice the Daily Minimum Quantity for each
         Day of the Shortfall  Period shall be ipso facto increased by the daily
         quantity of Shortfall Gas specified as aforesaid, but subject always to
         clause 3.66.

3.66     (a)      If the Producers  are or  will  be  unable  despite their best
                  endeavours  but having  regard to good oil field  practice  to
                  supply  upon and  subject to the terms and  conditions  herein
                  contained  any quantity of the  additional  Gas required to be
                  delivered  by a Schedule  A  Variation  Notice or a  Shortfall
                  Notice then they shall  forthwith  jointly give notice thereof
                  to the Purchaser and shall specify therein the extent to which
                  and period during which they expect to be unable to supply the
                  required quantities,  the reasons therefor, and the additional
                  Development  Work which in their opinion would be necessary in
                  order to meet the Purchaser's requirements.

         (b)      Upon receipt by the Purchaser of a  notice  given  pursuant to
                  paragraph (a) of this clause the Purchaser may either:

                  (i)      accept  the   Producers'   inability  to  supply  the
                           additional  Gas specified in which case paragraph (f)
                           of this clause shall apply, or

                           Producers' inability to supply or the extent (if any)
                           of  the  Development   Work  necessary  to  meet  the
                           Purchaser's requirements.

         (c)      Upon any reference  pursuant to  paragraph (b)  of this clause
                  the Independent Expert shall certify as to:

                  (i)      whether the Producers ought in all the  circumstances
                           (including  without  limiting the generality  thereof
                           the capacity of the existing Gas Delivery  System) be
                           excused from their  respective  liabilities  for such
                           non-delivery or any part thereof and

         (d)      Where  the  Independent   Expert   certifies  that  additional
                  Development   Work  is  necessary  to  meet  the   Purchaser's
                  requirements the Purchaser may either

                  (i)      require the  Producers  jointly to proceed  with such
                           additional  Development  Work in which case paragraph
                           (e) of this clause shall apply, or

                  (ii)     accept the  Producers'  inability  to supply in which
                           case paragraph (f) of this clause shall apply.

         (e)      Where  pursuant  to this  clause the  Purchaser  requires  the
                  Producers jointly to proceed with additional  Development Work
                  then the Producers  jointly  undertake  that they will proceed
                  with all  expedition to carry out the same and the  provisions
                  of clause 2.50 shall (mutatis mutandis) apply thereto.

         (f)      Where and to the  extent  that  pursuant  to this  clause  the
                  Purchaser accepts or an Independent  Expert certifies that the
                  Producers are unable to supply any part of the  additional Gas
                  requested  then no  Producer  shall  be  deemed  to have  made
                  default in delivery of such Gas and the Daily Minimum Quantity
                  and Monthly Minimum  Quantity for the period in question shall
                  be reduced accordingly.

3.67     Notwithstanding  the  foregoing  provisions  of  this  clause  3.60  no
         Producer  shall be obliged to supply Gas  pursuant to clauses  3.62 and
         3.63 to the extent that such supply would reduce the Proven Reserves of
         the Gas  Field  below the  Warranted  Quantities  unless  and until the
         Purchaser  shall first agree in writing that the  Warranted  Quantities
         shall be reduced to the resulting Proven Reserves.

                  clause)  this Agreement would otherwise be at an end paragraph
                  (a) shall apply on the basis that the  Purchaser  shall in any
                  Month be  entitled  to take  Make-up Gas  notwithstanding that
                  no Minimum  Monthly  Quantity applies for the Month,  PROVIDED
                  ALWAYS that the Purchaser's rights under this sub-clause shall
                  be suspended for any period during which  natural gas from the
                  Gas Field  is  not  being  supplied  either  to  the Purchaser
                  (pursuant to a renewal or replacement agreement)  or any other
                   party but the period of 5 years referred to in this paragraph
                  (b) shall be extended by the period of any such suspension.

4.30     Refund if Gas Field Depleted

         If at any  time  the  report  of  the  independent  reservoir  engineer
         pursuant  to clause 2.22 or any other  report of a  reservoir  engineer
         acceptable to the Purchaser and the Producers  establishes  that Proven
         Reserves in the Gas Field together with Proven Reserves in an Alternate
         Gas Field (if any) are less than those  necessary  for the  delivery of
         the  remaining  Gas  which  is  required  to be  delivered  under  this
         Agreement (that is, less than the lesser of:-

         (a)      the  balance  of  the   Dedicated  Quantity  remaining  to  be
                  delivered or

         (b)      the aggregate of the remaining  Annual Minimum Quantities plus
                  Make-up Gas)


<PAGE>

         then the  Purchaser  shall be entitled to have  delivered  to it to the
         extent to the deficiency of Proven Reserves  Make-up Gas in priority to
         any Annual Minimum  Quantities.  To the extent that it appears that the
         Purchaser  will not  thereby  receive  any  quantity  of Make-up  Gas a
         Producer shall forthwith upon demand repay to the Purchaser in cash all
         payments made to it in accordance  with paragraph (c) of clause 3.21 in
         respect of such amount  plus  interest  on all such  payments  from the
         respective dates of payment at the same rate as Recovery Interest.

         For the purposes of this clause:

         (i)      "Alternate  Gas Field"  means a gas field  (other than the Gas
                  Field)  from which the  Producers  shall be  entitled  and are
                  capable of supplying Gas for the purposes of this Agreement.

         (ii)     "Proven Reserves in an Alternate Gas Field" means the quantity
                  of Proven Reserves in an Alternate Gas Field which are at that

         shall request the Australian Bureau of Statistics to provide figures or
         indices which shall give an  equivalent  comparison to that provided by
         the CPI.

4.42     If the  parties  are  unable to obtain  from the  Australian  Bureau of
         Statistics  figures or indices which given an equivalent  comparison to
         that  provided  by the said  index  and are  unable  to  agree  between
         themselves as to such figures or indices  either the Producers  jointly
         or the  Purchaser  may request the  President for the time being of the
         Institute  of  Chartered  Accountants  in  Australia  or his nominee to
         provide at each review date figures or indices which give an equivalent
         comparison to that  contemplated by the CPI and such figures or indices
         shall then for the purposes of this Agreement be deemed to be the CPI.

4.50     Increase in Commonwealth Imposts

         (a)      For the purpose of this Clause the Base Level of Imposts means
                  the  aggregate of  N.T. Imposts and Commonwealth Imposts as at
                  the Development Date.

         (b)      If any  increase  of  Commonwealth  Imposts  has the effect of
                  increasing  the  aggregate  of  N.T. Imposts and  Commonwealth
                  Imposts to 150% or more of the Base Level of Imposts then each
                  of the Producers shall be entitled to recover as Imposts Price
                  in respect of Gas  delivered  by it any part of that  increase
                  and the  amount of any  subsequent  increase  of  Commonwealth
                  Imposts  which has the effect of  increasing  the aggregate of
                  N.T. Imposts and Commonwealth  Imposts beyond 150% of the Base
                  Level of Imposts.

                  increasing  the  aggregate  of N.T.  Imposts and  Commonwealth
                  Imposts to 110% or more of the Base Level of Imposts then each
                  of the Producers shall be entitled to recover as Imposts Price
                  in respect of Gas  delivered by it the whole of such  increase
                  or increases of N.T.  Imposts which since the Development Date
                  or the Date of Last Review (whichever is applicable)  together
                  shall have had the effect of so  increasing  the  aggregate of
                  the N.T.  Imposts and the Commonwealth  imposts.  The "Date of
                  Last  Review"  shall  mean the date on which a  Producer  last

5.00     ADJUSTMENT OF GAS TO SPECIFICATION

5.10     Rights of Purchaser

         5.11     Without  prejudice  to any  other  rights or  remedies  of the
                  Purchaser against a Producer for losses incurred, in the event
                  that Gas tendered  for  delivery  hereunder by any Producer (a
                  "defaulting Producer") fails to meet any of the specifications
                  set forth in Schedule B:-

                  (a)      The  Purchaser  shall  have the  right to  refuse  to
                           accept   further   deliveries   from  the  defaulting
                           Producer  until such failure is  rectified,  and that
                           Producer   shall  become   liable  for  the  cost  of
                           alternative  fuel  supply in  accordance  with clause
                           3.40.  The  Purchaser  shall  forthwith  notify  such
                           refusal by  telephone  to the  Producers  jointly and
                           shall confirm the same by written notification within
                           24 hours specifying the nature of the deficiency.

                  (b)      The  Purchaser may  knowingly or  unknowingly  accept
                           such Gas and may install,  operate and maintain  such
                           facilities  as may be  required  to cause such Gas to
                           meet such  specifications in which case the Purchaser
                           shall have the right to recover  from the  defaulting
                           Producer all costs incidental thereto, including fuel
                           supply damages,  depreciation,  overhead and costs of
                           capital  all of  which  may  be  deducted  from  sums
                           payable by the Purchaser to the  defaulting  Producer
                           hereunder.

         5.12     Without  prejudice  to any  other  rights or  remedies  of the
                  Purchaser against the defaulting  Producer for losses incurred
                  in the  event  that Gas  supplied  fails to  achieve a minimum
                  Gross Heating Value of 36MJ/m3,  the defaulting Producer shall
                  compensate the Purchaser for all  additional  costs payable by
                  the Purchaser  associated  with the movement of the additional
                  volumes of Gas  through the  Pipeline  required to achieve the
                  energy  equivalence of Gas rated at 36MJ/m3 over the period of
                  delivery  of  the  specification   breach.  Any  statement  or
                  calculation  of such  costs  by the  Purchaser  shall be prima
                  facie evidence thereof.

         5.13     It shall be no  defence  to any  action by the  Purchaser  for
                  recovery of costs  pursuant to clauses  5.11 and 5.12 that the
                  Purchaser  shall not have  personally  incurred  such costs or
                  shall be entitled to recoup such costs from the Consumers.

5.20     Removal of Constituents

         So long as the Gas remains within specification,  the Producers jointly
         may, prior to delivery thereof or otherwise as the Purchaser may agree,
         submit  such Gas to any process the  Producers  jointly  desire for the
         removal of constituents or elements  therein other than for the removal
         of methane (except where methane removal is an unavoidable  consequence
         of the removal of other  constituents).  Such separate  constituents or
         elements will remain the property of the  Producers in their  Ownership
         Percentages.

5.30     Quality Tests

         The  Purchaser and the  Producers  jointly shall agree upon  reasonable
         methods and  procedures  and determine the  instruments  to be used for
         making  tests to determine  whether Gas conforms to the  specifications
         set forth in Schedule B.

         If the parties are unable to agree upon such  procedures  any party may
         refer the question for determination by an Independent Expert.

6.10     Measuring Equipment

6.11     Installation

         The Purchaser  shall ensure that the Pipeline  Operator  shall furnish,
         install,  maintain  and  operate  at  the  Custody  Transfer  Area  all
         measuring equipment.

6.12     Compliance with Standards

         All  measuring  equipment  shall be of a type approved for the intended
         use  under the  provisions  of the  appropriate  authority  where  such
         approvals are required,  or of a type approved by the Producers jointly
         where  such  approvals  are  not  required  (such  approval  not  to be
         unreasonably withheld).

6.13     Check Measuring Equipment

         The Producers jointly may install and operate check measuring equipment
         within the Custody Transfer Area (as part of Development Work) provided
         the same does not interfere with the operation of the Pipeline.

6.14     Pulsation Dampening

         If there are any compression  facilities upstream of the Field Delivery
         Station,  the  Producers  jointly  undertake  that they will provide or
         cause to be provided sufficient  pulsation dampening equipment (as part
         of Development  Work) to ensure that the compression  facilities do not
         interfere with the operation of the Pipeline.

6.15     Calibration

         (a)      The accuracy of the  measuring  equipment  shall be tested and
                  verified  by the  Purchaser  once each  month or at such other
                  intervals as may be required by the type of equipment.

         (b)      Reasonable notice of the time and nature of each test shall be
                  given to the Producers jointly to permit them to arrange for a
                  representative   to  observe  the  test  and  any  adjustments
                  resulting from such test. If, after notice, the Producers fail
                  to have a  representative  present,  the  results  of the test
                  shall nevertheless be considered accurate.


<PAGE>

6.16     Correction

         If at any time,  any of the  measuring  equipment is found to be out of
         service or  registering  inaccurately,  it shall be adjusted at once to
         read as accurately as possible and the readings of such equipment shall
         be adjusted to zero error for a period definitely known or agreed upon,
         or if not known or agreed  upon,  for  period of  sixteen  (16) days or
         one-half  (1/2) of the elapsed  time since the last test,  whichever is
         shorter.  The  measurement  during  the  appropriate  period  shall  be
         determined  by the  Pipeline  Operator  on the  basis of the best  data
         available using the first of the following methods which is feasible:

         (a)      by using the data recorded by any check measuring equipment if
                  installed and accurately registering; or

         (b)      by making the appropriate correction if the deviation from the
                  accurate  reading  is  ascertainable  by  calibration  test or
                  mathematical calculation; or

         (c)      by estimating  based upon receipts or deliveries under similar
                  conditions  during a period when the equipment was registering
                  accurately.

6.17     Additional Tests

         (a)      The  Producers  jointly   may  require   additional  tests  at
                  reasonable intervals.

         (b)      If upon testing,  the deviation  from the accurate  reading is
                  found to be less than two percent (2%),  each  Producer  shall
                  bear its Ownership Percentage of the expense of the additional
                  test.

6.18     Inspection of Equipment and Records

         (a)      Each party shall have the right at all times to have access to
                  the Custody Transfer Area and to inspect  measuring  equipment
                  installed or furnished by the other.

         (b)      Each  party  shall  have the right to  inspect  the charts and
                  other  measurement  or test  data of the  other  at all  times
                  during normal business hours.

         (c)      The reading,  calibration and adjustment of such equipment and
                  changing  of the  charts  shall  be done  only  by the  person
                  installing or furnishing  the same and each Producer  shall be
                  entitled  to be  present  at such time but shall be subject to
                  all  reasonable  requirements  of the Pipeline  Operator  with
                  regard to the  security of the Custody  Transfer  Area and the

6.20     Method of Measurement

         All  measurements,  calculations  and  procedures  used in  determining
         volume, except for the correction for deviation from Boyle's Law, shall
         be  made in  accordance  with  the  instructions  contained  in the Gas
         Measurement  Committee Report Number 3 of the American Gas Association,
         dated April 1955,  together  with all presently  existing  supplements,
         amendments and appendices to the said Report.  Such  instructions to be
         converted  where  necessary for  compliance  with  Australian  Standard
         AS1000-1979   "The   International   System  of  Units   (SI)  and  Its
         Application",   the  Commonwealth   "Weights  and  Measures   (National
         Standards) Act 1960-1966" and Regulations thereunder and the Australian
         Gas Association  publication  "Metric Units and Conversion  Factors For
         Use In the Australian Gas Industry".  The correction for deviation from
         Boyle's  Law  shall  be  determined  from the  data  contained  in "PAR
         Research Project NX-19" as published by the American Gas Association in
         1962,  or any revision  thereof  acceptable  to the  Purchaser  and the
         Producers jointly.

6.30     Unit of Measurement

         The unit of volume for purposes of measurement hereunder,  shall be one
         103m3 of Gas and be  expressed to the nearest  one-tenth  103m3 or such
         other unit of volume agreed to by Purchaser and the Producers jointly.

6.40     Atmospheric Pressure

         For the purpose of measurement atmospheric pressure shall be determined
         by a  recognised  formula  applied to the  nearest one  hundredth  of a
         kilopascal absolute (.01 kPa) and deemed to be a constant.

6.50     Flowing Temperature

         The  flowing  temperature  of Gas  shall be  determined  by means of an
         approved recording thermometer of standard make. The arithmetic mean of
         all  readings  each day shall be deemed to be the Gas  temperature  and
         shall be used in computing volume.

6.60     Determination of Gas Characteristics

         The gas characteristics  including,  without limiting the generality of
         the foregoing,  Gross Heating  Value,  relative  density,  nitrogen and
         carbon  dioxide  content  of gas  shall  be  determined  by  continuous
         recording equipment or by laboratory equipment. If continuous recording
         equipment is used the  arithmetic  mean of all  recordings for each day
         will be used to  determine  gas  characteristics.  If spot  samples are
         taken or a spot sampler is used, gas characteristics will be determined
         from  the  analysis  of the  samples  using  laboratory  equipment  and
         recognised analytical methods.

                  information  promptly after receipt  thereof from the Pipeline
                  Operator.

         (b)      The Producers  jointly shall cause to be sent to the Purchaser
                  promptly  upon  request  copies  of the  information  kept  or
                  obtained by them.

6.80     Preservation of Measurement Records

         The parties  shall  preserve  all  measurement  test data,  measurement
         charts and other  similar  records for the greater of a period of seven
         (7) years or the minimum period  required by record  retention rules of
         any governmental  agencies having  jurisdiction or the currency of this
         Agreement.

                  overcome  the effect of the Force  Majeure or  Pipeline  Force
                  Majeure as quickly as possible  but this shall not require the
                  settlement of strikes or labour  disputes on terms contrary to
                  the reasonable wishes of the party affected.

10.10    Negative Pledges

10.11    Each of the Producers  hereby gives to the Purchaser a negative  pledge
         namely a pledge that it will not  without the consent of the  Purchaser
         charge its interest in the Petroleum Lease other than in respect of:

         (i)      a charge which it shall be entitled to give to a financier for

                  Operating Agreement.

10.12    Each of the Producers  shall  be  entitled  to  be  released  from  the
         negative pledge given pursuant to clause 10.11 hereof:

         (a)      at any  time  upon  the  Producers  establishing  and  jointly
                  covenanting to maintain during the balance of the term of this
                  agreement  Proven  Reserves  of  not  less  than  250%  of the
                  aggregate of:

                           pursuant to this Agreement  in  Contact Years 1 to 20

                  (ii)     the Maximum  Delivery  Obligations  as defined in the
                           Alice Springs Contract still to be delivered pursuant
                           to that Contract; or

         (b)      at any time after the expiration of two years from the Date of
                  Initial  Delivery upon the Producers  establishing and jointly

                           to that Contract; or

         (c)      at any time  upon  the  Producer  giving  to the  Purchaser  a
                  performance bond in respect of its Ownership  Percentage of 20
                  million dollars  escalated in accordance with movements in the
                  CPI  from  the  31st  March,  1985 to the  date on  which  the
                  performance bond is given.


<PAGE>

         The Purchaser  agrees that the  requirements  of paragraph (a), (b) and
         (c) above are interchangeable at the option of any Producer at any time
         and from  time to time to the  intent  that if,  by way of  example,  a
         Producer shall have secured a release from the negative pledge given by
         it by satisfying the requirements of paragraph (a) it may thereafter be
         discharged from its obligations pursuant to paragraph (a) by satisfying
         the  requirements  of paragraph  (b) or paragraph (c) and upon doing so
         the  Purchaser  shall  release and  discharge  that  Producer  from its
         obligations pursuant to paragraph (a). If, as aforesaid,  that Producer
         shall have elected to satisfy the  requirements  of paragraph (c), that
         Producer may thereafter be discharged from its obligations  pursuant to
         paragraph  (c) and the  Purchaser  shall  return to that  Producer  its
         performance  bond upon satisfying the requirements of paragraph (b) and
         so on.

10.13    (a)      A Producer may at any time request the Purchaser to review its
                  need for a continuing negative pledge from that Producer.

         (b)      The  Purchaser  shall in good  faith  conduct  such  review in
                  response  to a request  made on or after five years  after the
                  Date of Initial Delivery and at intervals of not less than two
                  years thereafter.

         (c)      In the event that the Purchaser determines at any time that it
                  has no reasonable  need for a continuing  negative pledge from
                  that  Producer it shall release the Producer from its negative
                  pledge.

10.20    Default by Producers

         If any one or more of the following events occurs, namely:

         (a)      if any order is made for the  liquidation  of a Producer  or a
                  Producer  institutes any proceedings or  arrangements  for its
                  liquidation  in whole or in part or for the  appointment  of a
                  receiver or any  receiver is appointed of any of its assets or
                  a Producer  is unable to pay its debts  within the  meaning of
                  that expression in the Companies  legislation of the Territory
                  and  as a  result  of  any  of  the  foregoing  the  Purchaser
                  reasonably believes that the supply of Gas by that Producer to
                  the  Purchaser is placed in jeopardy or that the Purchaser may
                  be  unable  to  obtain  a good  discharge  in  respect  of its
                  obligations;

         (b)      if a Producer  make default in the due  performance  of any of
                  its substantial  covenants or obligations under this Agreement
                  (not being a covenant or obligation of the kind referred to in
                  sub-clause  (c) of this  clause)  and if a  Producer  fails to
                  remedy or to commence and diligently continue in good faith to
                  remedy that  default  within a  reasonable  time after  notice
                  specifying the default is given to the Producer; or

         (c)      if a Producer  makes  default in the due payment of any moneys
                  payable hereunder and any such default remains  unremedied for
                  a period  exceeding  thirty days after notice  specifying  the
                  default is given to the Producer;


<PAGE>

         then and in any such events the  Purchaser  may by notice in writing to
         the  relevant  Producer  (so far as the  separate  Agreement  with that
         Producer is concerned):-

                  (i)      Suspend its  obligations to make payments  under this
                           Agreement other than payments under clause 7.10 until
                           the default is remedied; or

                  (ii)     Terminate  such  separate  Agreement   whereupon  the
                           Purchaser  shall  have no further  liability  to that
                           Producer  hereunder  and shall be entitled to recover
                           from  that  Producer  as and  by  way  of  liquidated
                           damages  the  net  present   value   (determined   as
                           hereinafter provided) of the liquidated damages which
                           would be recoverable  from that Producer  pursuant to
                           clause 3.43 if that Producer made default in delivery
                           of that  quantity of  Obligation  Gas  required to be
                           delivered   by  that   Producer   from  the  date  of
                           termination by the Purchaser as aforesaid to the date
                           on  which  this   Agreement   would   otherwise  have
                           terminated ("Date of Expiry").  The net present value
                           of such damages shall be determined by:

                           (A)      ascertaining  the  amount of the  liquidated
                                    damages which would be recoverable from that
                                    Producer in respect of the Month immediately
                                    preceding  the date of  termination  if that
                                    Producer  had made  default in  delivery  of
                                    133%  of  its  Ownership  Percentage  of the
                                    Monthly Minimum Quantity during that month;

                           (B)      assuming  that the same amount of liquidated
                                    damages  as in  paragraph  (A)  above  would
                                    apply in respect of each Month from the date
                                    of termination to the Date of Expiry;

                           (C)      discounting   the  amounts  referred  to  in
                                    paragraph (B) above to present  value at the
                                    rate of 8 percent per annum.

                           Termination  of this  Agreement  with  respect to any
                           Producer shall be without  prejudice to the rights of
                           any party accruing prior to termination,  but subject
                           thereto  and to the  provisions  of this  clause  the
                           Purchaser  shall  not  have  and  shall  not make any
                           further or other  claims upon the  relevant  Producer
                           arising out of or in any way in  connection  with any
                           default  by  the  Producer  or  termination  of  this
                           Agreement as aforesaid.  Upon the termination of this
                           Agreement as aforesaid no further  liquidated damages
                           under clause 3.43 shall accrue.

10.30    Default by Purchaser

         If the  Purchaser  in  relation  to any  Producer  is in default in the
         observance or  performance  of any  substantial  covenant or obligation
         under this Agreement and such default shall continue for a period of 90
         days after written notice  specifying the default shall have been given
         to the  Purchaser by such  Producer then that Producer may by notice in
         writing to the Purchaser (so far as the separate  Agreement between the
         Purchaser and that Producer is concerned):


<PAGE>

         (i)      Suspend   deliveries  of  Gas  hereunder   provided  that  the
                  Purchaser  shall remain liable to pay that Producer the amount
                  due to it for Monthly Minimum  Quantities  which will not give
                  any entitlement to Make-up Gas; and/or

         (ii)     Terminate such separate Agreement.

         In the event that a Producer  terminates  such  separate  Agreement  as
         aforesaid  the  Purchaser  shall pay to that  Producer as and by way of
         liquidated damages its Ownership Percentage of:

         (i)      the  unrecouped  balance  of  Development  Expenditure  and in
                  addition  such part of the sum of $6.5 million  referred to in
                  the definition of Development Expenditure as has been expended
                  to the date of termination; and

         (ii)     the net  present  value of the Base  Price  for the  aggregate
                  Annual Minimum Quantities remaining to be delivered under this
                  Agreement as at the date of termination. The net present value
                  as aforesaid shall be determined by:

                  (A)      Ascertaining  the Base Price  which  applied or would
                           have   applied   under  this   Agreement   using  the
                           assumptions set out in (B) below in each Quarter from
                           the start of the Contract  Year in which  termination
                           occurs until the aggregate Annual Minimum  Quantities
                           remaining to be delivered  under this Agreement would
                           have been delivered;

                  (B)      The   actual   impact  on  the  Base   Price  of  CPI
                           Escalation,  Mega CPI Escalation and Fuel  Escalation
                           is to be averaged on an annual  basis over  whichever
                           of the following  periods prior to termination is the
                           longer namely:

                           (I)      three years; and

                           (II)     the  period   since  the   Date  of  Initial
                                    Delivery.

                  (C)      Assuming the Base Price  ascertained in paragraph (A)
                           above for the four  Quarters in each of the  relevant
                           Contract  Years and  dividing the sum thereof by four
                           to derive the average  Base Price  applicable  to the
                           respective Contract Years.

                  (D)      Multiplying the Annual Minimum  Quantities  remaining
                           to be delivered under this Agreement from the date of
                           termination  by  the  average  Base  Price  for  each
                           relevant Contract Year to derive the price payable by
                           the Purchaser in respect of each such Contract Year.

                  (E)      Discounting  each  of  the  amounts  referred  to  in
                           paragraph  (D) above to  present  value as a mid year
                           stream at the rate of 7 percent  per annum  above the
                           CPI for the relevant  Contract Year, and  aggregating
                           the resulting amounts.

         (a)      No assignment by a Producer of this Agreement or of its rights
                  hereunder  shall be of any effect  whatsoever  unless with the
                  written  consent of the  Purchaser  which consent shall not be
                  unreasonably  withheld  in  the  case  of  a  financially  and
                  technically   competent  assignee  PROVIDED  ALWAYS  that  the
                  assignee  shall  covenant in writing with the  Purchaser to be
                  bound by all the terms and conditions of this Agreement so far
                  as they apply to the assignor.

         (b)      No  assignment  by the  Purchaser of this  Agreement or of its
                  rights hereunder shall be of any effect whatsoever unless with
                  the written  consent of each of the  Producers  which  consent
                  shall  not  be   unreasonably   withheld  in  the  case  of  a
                  financially and technically competent assignee PROVIDED ALWAYS
                  that  the  assignee   shall  covenant  in  writing  with  each
                  Purchaser to be bound by all the terms and  conditions of this
                  Agreement so far as they apply to the assignor.

         (c)      The  Purchaser's  consent  to  any  proposed  assignment  by a
                  Producer  which is  also  a Mereenie  Producer  shall  not  be
                  deemed  unreasonably  withheld where that  Producer has failed
                  to satisfy  the Purchaser  that  the  resulting  loss  of  the
                  Purchaser's right of set off under clause 7.50 hereof will not
                  adversely  affect  the  Purchaser's  interests  to a  material
                  degree, or unless that Producer's  interests in  the Gas Field

                  deemed to have been  adversely  affected  to a material degree
                  where a  Producer who is a  Mereenie Producer  provides to the
                  Purchaser a letter of credit or other  acceptable  security in
                  an amount equal to the net  present value  (calculated using a
                  discount rate of 12% per annum)  of $2.7 million per annum for
                  each unexpired year of this Agreement up to Contract Year 20.

         listed in  Column 2  above is  the year  in which  the Date  of Initial
         Delivery occurs and Column 1 shall be adjusted accordingly.

(ii)     If the Date of  Initial  Delivery  is other  than 1st July in the first
         Contract Year then the Annual Minimum  Quantity for that first Contract
         Year shall be the quantity specified in Column 3 in respect of the year
         in which the Date of Initial Delivery occurs divided by 182 if the Date
         of Initial Delivery is prior to 30 June 1987, and 365 in any other case
         and then  multiplied  by the  number of days  from the Date of  Initial
         Delivery to the end of that first Contract Year.

(iii)    The Daily  Minimum  Quantity for that first  Contract Year shall be the
         Annual  Minimum  Quantity for that first  Contract  Year  determined as
         aforesaid  divided  by the  number  of days  from the  date of  Initial
         Delivery to the end of that first Contract Year.

(iv)     If the Date of  Initial  Delivery  is later  than 1 July  1986 then the
         aggregate  Annual  Minimum  Quantities  shown  in  Column  3  remaining
         undelivered  on 1 July  2012  shall be taken  by the  Purchaser  in the

TABLE III
NOTES

         1.       This table is derived in the case of:

                  (a)      Coln 3 to Coln 6 from Table I; and

                  (b)      Coln's 7 and 9 from Table II.

         2.       Coln's 3, 5 and 9,  respectively,  are derived by applying the
                  Quarterly CPI (Coln 5 Table I), MEGA (Coln 6 Table I) and Fuel
                  (Coln 4 Table II) escalators to that portion of the Base Price
                  (including  any previous  such  escalations)  as apply to that
                  escalator.  The result being the annual  increment in the Base
                  Price attributable to that escalator.  For the purpose of this
                  calculation the respective portions are:

                  (a)      in the June Quarter 1985:

                           (i)      $0.375 for CPI Escalation
                           (ii)     $1.125 for Mega Escalation
                           (iii)    $1.500 for Fuel Escalation

                  (b)      In latter quarters the June 1985 Base plus escalation
                           to the quarter of concern.

         3.       Coln's 4, 6 and 7 are  derived  for any  quarter by adding the
                  respective  cummulative  total in the previous  quarter to the
                  increment in the current quarter.

                  Example

                           Coln 4, Row 17 = [0.395 + 0.0158] = 0.411

         4.       Coln 8 = sum of Coln's 4, 6 and 7.

         5.       Coln 10 = sum of Coln's 8 and 9.

                             FUEL ESCALATION FORMULA


1.       DATA SOURCE

         The  following  data  can  be  obtained  from  the  Electricity  Supply
         Association of Australia (ESAA)  publication  "The  Electricity  Supply
         Industry  in  Australia"  issued  in about  April  each  year with data
         relating to the previous  financial year. This data is available to all
         ESAA members,  of which NTEC is one, and will be made  available to the
         producers  when it  becomes  available  to  NTEC.  In the  event of the
         intended  source  of  data  becoming  unavailable  or any of the  bases
         therefor  being  materially  altered  then in the absence of  agreement
         between the  Purchaser  and the  Producers  jointly the matter shall be
         referred to an Independent Expert for determination.

2.       EXTENT OF DATA

         Data is required to be totalled  for each  Utility (as the term is used
         by ESAA) for each of:

         (1)      NSW;
         (2)      QUEENSLAND; and
         (3)      WESTERN AUSTRALIA

         provided that should  complete data sets become  available for Victora,
         and or, South Australia these States should also be incorporated.

3.       DATA REQUIRED

         The following data is required:-

         (a)      Income from  all  sales  for  each  Utility  for  the relevant
                  financial year in $M (Table 7, Item 7.7 of ESAA document).

         (b)      Consumption of  electricity  for each Utility for the relevant
                  financial  year in million of kWh (Table 6, Item 6.7,  of ESAA
                  document).

         (c)      The CPI (as  herein  defined)  for the relevant financial year
                  expressed as a percentage.

4.       DERIVATIONS FROM DATA

         Step 1:  Aggregation

         Add  each of (a) and (b) in 3 above  to  produce  a three  State  total
         (hereinafter A and B respectively).


<PAGE>

         Step 2:  Fuel Cost Ratio

         The Fuel Cost Ratio (F) for the purpose of  calculating  the fuel price
         escalator shall be 0.24.

         Step 3:  Average Sale Price

         Derive  the  average  sale  price  of  electricity  during  the year in
         cents/kWh  by dividing  total income from all sales (See 3(a) above) by
         consumption (see 3(b) above).

                                      G = A
                                          -
                                          B

         Step 4:  Annual Percentage Sales Price Movement

         Derive  the  annual   percentage  change  in  the  sale  price  of  (H)
         electricity.

                                  (Gt -G t-1)
                               H = _________ x 100

                                     Gt-1

                 where subscript:   t refers to the present year

                           exceeding the quantities provided for in clause 3.22)
                           and not in any event  exceeding the quantity which on
                           that Day the  Purchaser is entitled to have  accepted
                           for  transmission  through the Pipeline and which the
                           Pipeline is capable of accepting on that Day; and

                  (ii)     the Day and hour  when  such  nomination  shall  take
                           effect  not being  less than four hours from the time
                           of nomination,

                  the parties shall agree on more frequent nomination procedures
                  and shorter nomination times under paragraph (ii) in the event
                  that the Gas  Delivery  System is  automated  or for any other
                  reason is able to accommodate such changes.

         (b)      The total  quantity  of Gas which  would be  delivered  by all
                  Producers  during  any Day if  delivery  was to  occur  at the
                  nominated rate or rates shall constitute Obligation Gas.

         (c)      All  nominations  may  be  made  by  telephone  but  shall  be
                  confirmed by written notification within 24 hours.

         (d)      Delivery  shall be  maintained  at the rate  specified  in the
                  Purchaser's most recent nomination until superseded by a later
                  nomination.

         (e)      The  Purchaser  shall  prior  to  the  commencement  of  every
                  Contract Year give notice to the Producers jointly of:

                  (i)      Its likely annual  requirements  of  Gas for the next
                           five Contract Years;

                  (ii)     Its likely Monthly  requirements  of Gas for the next
                           twelve Months.

         (f)      The Purchaser  shall prior to the  commencement  of each Month
                  give  notice to the  Producers  jointly  of its  likely  daily
                  requirements of Gas for that Month.


<PAGE>

3.24     If on any Day or Days the Purchaser  requires  amounts of Gas at a rate
         in excess of the Daily Peak  Demand  Quantity  it may request by notice
         given to the Producers jointly that deliveries be made at such rate and
         each Producer will deliver its Ownership Percentage of Gas at such rate
         PROVIDED  HOWEVER  that if the  Producers  are  unable  to do so having
         regard to the capacity of the then  existing  Gas  Delivery  System and
         their  obligations  under  other gas sales  contracts  entered  into in
         accordance  with this  Agreement it shall notify such  inability to the
         Purchaser  and shall not be  obliged  to  deliver  Gas in excess of its
         Ownership Percentage of the Daily Peak Demand Quantity.

3.25     (a)      In the event  that in  any Month  of  any  Contract  Year  the
                  Purchaser  purchases  and takes  Gas in excess of the  Monthly
                  Minimum Quantity less any increase  therein effected  pursuant
                  to a Shortfall  Notice plus all Make-up Gas  accumulated up to
                  and including that Month, such excess shall be carried forward
                  and credited against the Purchaser's subsequent commitments to
                  purchase and take the Monthly Minimum Quantity.

         (b)      No  credit   pursuant  to  paragraph   (a)  shall  reduce  the
                  Purchaser's commitments to purchase and take below one half of
                  the  Monthly  Minimum   Quantity  in  any  Month.  Any  credit
                  remaining  after any  reduction to such level shall be carried
                  forward as a credit in a subsequent month or months.

         (c)      If by the  application  of a credit  pursuant to paragraph (a)
                  the  Purchaser in any Month shall  purchase and take less than
                  the Monthly  Minimum  Quantity in that Month then the quantity
                  of  Gas  equivalent  to the  difference  between  the  Monthly
                  Minimum  Quantity  in that  Month  and the  quantity  actually
                  purchased  and taken by the  Purchaser  in that Month shall at
                  the option of the  Producers  jointly be debited  against  the
                  Dedicated Quantity.

3.30     Continuity of Supply

3.31     It is an  essential  term  of  this  Agreement  that  supply  of Gas in
         accordance   with  this  Agreement   shall  commence  at  the  time  of
         commissioning of the Pipeline as notified pursuant to clause 2.30.

3.32     Subject to the terms of this Agreement each Producer undertakes that it
         will  throughout  the term of this  Agreement  maintain  continuity  of
         supply to the  Purchaser  at the inlet  flange of the  Pipeline  of its
         Ownership  Percentage  of  the  Purchaser's   requirements  of  Gas  in
         accordance with this Agreement.

3.33     The  Producers  jointly may  nevertheless  interrupt  supply to perform
         reservoir  tests and  evaluations in accordance with and subject to the
         following limitations and procedures:

         (a)      There shall be not more than 6 occasions  of  interruption  in
                  any Contract Year and the total duration of such interruptions
                  shall not exceed 144 hours in any Contract Year.


<PAGE>

         (b)      The dates and times chosen for testing  shall be arranged with
                  the Purchaser and with the Pipeline Operator and with the Palm
                  Valley  Producers  as far as  possible  in  advance  and shall
                  always unless otherwise agreed  correspond with periods of low
                  demand for electricity and shall not unless  otherwise  agreed
                  correspond with periods of interruption  under the Palm Valley
                  Agreement.

         (c)      The   Producers   jointly   shall   be   allowed    additional
                  interruptions  for  unforeseen  and  unscheduled  events  (not
                  constituting   Force   Majeure)  not   exceeding  a  total  of
                  forty-eight (48) hours in each year.

         (d)      In the event of any  interruption in transmission  through the
                  Pipeline or cessation of electricity  production at any of the
                  power stations the Purchaser may notify the Producers  jointly
                  and  the  Producers   jointly  undertake  to  use  their  best
                  endeavours to carry out testing during such  interruptions  in
                  lieu of those provided for in this clause.

3.34     Whenever a Producer  becomes  aware that it cannot or may become unable
         to maintain  continuity of supply in accordance  with this Agreement it
         shall forthwith  advise the Purchaser and the Palm Valley  Producers of
         that fact so as to enable the  Purchaser at the earliest  possible time
         to  make  arrangements  for  purchase  of  Gas  from  the  Palm  Valley
         Producers.

3.40     Failure to Supply

3.41     In the event that for any reason other than Force  Majeure or permitted
         interruptions  under  clause  3.33 a  Producer  fails  to  deliver  its
         Ownership  Percentage of the full amount of  Obligation  Gas on any Day
         then that Producer  shall be deemed to have made default in delivery of
         the  quantity of Gas  equivalent  to its  Ownership  Percentage  of the
         quantity  of  Obligation  Gas on that Day  minus  the  quantity  of Gas
         actually  delivered on that Day by the  Defaulting  Producer  ("Default
         Gas") and the  following  provisions  of this  clause  3.40 shall apply
         PROVIDED THAT the Defaulting  Producer shall be deemed not to have made
         default in delivery as aforesaid if:

         (a)      (i)      such failure does not exceed two continuous Days;

                  (ii)     the  Defaulting  Producer  delivers not less than its
                           Ownership Percentage of the Daily Minimum Quantity on
                           that Day; and

                  (iii)    the Defaulting Producer delivers within the following
                           two days an additional  quantity of Gas equivalent to
                           the quantity of Default Gas.

         or

         (b)      the Defaulting  Producer  delivers or procures the delivery of
                  Gas or natural gas with  specifications to which the Purchaser
                  has agreed from a source other than from the  Petroleum  Lease
                  to the Field  Delivery  Station  or any other  field  delivery
                  station  linked to the  Pipeline and the  Defaulting  Producer
                  shall be duly paid the Contract Price for any such gas.


<PAGE>

         or

         (c)      clause 3.66 operates to relieve  the  Defaulting Producer of a
                  default.

3.42     Upon a Defaulting  Producer making default in delivery as aforesaid the
         Defaulting  Producer  shall  have  the  opportunity  to  supply  to the
         Consumers at their various points of consumption other energy in a form
         compatible  with the power  generation  equipment of NTEC and having an
         energy  content in whole or in part  equivalent to the Default Gas. Any
         such  other  energy  shall  be  supplied  at the  cost  and risk of the
         Defaulting Producer without charge to the Consumers,  and the Purchaser
         shall duly pay for such other energy so supplied the Contract Price for
         Gas having an energy content equivalent thereto.

3.43     If the  Defaulting  Producer  shall have made  default in  delivery  as
         aforesaid and if that Producer shall not have delivered other energy in
         exercise of its right under  clause 3.42 then the  Defaulting  Producer
         shall  subject  to  clause  3.43A  promptly  pay and  reimburse  to the
         Purchaser by way of liquidated damages the amount (if any) by which the
         Delivered  Cost of Substitute  Energy  exceeds what would have been the
         Contract  Price of an  amount  of  Obligation  Gas  deliverable  by the
         Defaulting Producer having an energy value equivalent to the Substitute
         Energy but not  exceeding  the energy value of the Default Gas provided
         that such Substitute  Energy shall be obtained as far as practicable in
         the circumstances at the least cost.

         For the purpose of this clause:

         (a)      The term  "Delivered  Cost" shall mean the unit cost  actually
                  incurred by NTEC or which would have been incurred by NTEC had
                  it been the  Consumer in relation to the  relevant  Substitute
                  Energy;  the cost  actually  incurred  by any  other  Consumer
                  (whether greater or smaller) shall be irrelevant;

         (b)      The term "Substitute  Energy" shall mean the total quantity of
                  energy  actually  consumed by all  Consumers at their  various
                  points of  consumption  for the purpose of  maintaining  their
                  power  generation  or  other  operations  as a  result  of the
                  Defaulting   Producer  having  made  default  in  delivery  as
                  aforesaid.

         (c)      If any Substitute  Energy is held in stock by the Consumers it
                  shall be costed on a  replacement  basis  from the  Consumers'
                  inventory at the relevant point of consumption.

3.43A    Where on any Day the amount of Obligation Gas exceeds the Daily Maximum
         Quantity (the difference being hereinafter  called "the Excess Amount")
         then the Defaulting  Producer's obligation to pay liquidated damages in
         regard to such Excess Amount under clause 3.43 shall be reduced by 90%.

3.44     The Purchaser  shall at the request of any Producer permit a registered
         company  auditor  nominated by that  Producer to have access to such of
         the books and records of the Purchaser as may be necessary to check any
         claims by the Purchaser pursuant to clause 3.43.


<PAGE>

3.45     Save as provided in this clause 3.40 no Producer shall be liable to the
         Purchaser or any of the Consumers  (and the Purchaser  shall  indemnify
         and keep  indemnified each Producer against any such liability) for any
         other or  consequential  loss or damage resulting from the failure of a
         Producer  to supply its  Ownership  Percentage  of any  Obligation  Gas
         during  the  term of the  agreement  including  inability  to  generate
         electricity loss of electricity supply or loss of profits.  No Producer
         shall  in any  event  be  liable  for  any  liability  incurred  by the
         Purchaser under the Gas Supply Agreements.

3.46     It shall be no defence to any action by the  Purchaser  for recovery of
         damages  pursuant  to  clause  3.43 that the  Purchaser  shall not have
         personally  incurred  the  cost of the  Substitute  Energy  where  such
         Substitute Energy has been acquired by the Consumers or any of them.

3.47     If a Producer  becomes a  Defaulting  Producer  under this  clause each
         other  Producer  shall be obliged to deliver  each Day on the terms and
         conditions  herein  contained a quantity of Gas equal to the proportion
         of Default Gas which its  Ownership  Percentage  bears to the aggregate
         Ownership  Percentages  of all  Producers  other  than  the  Defaulting
         Producer.

3.50     The Final Contract Years

3.51     A  Producer  ("the  Notifying  Producer")  may at any time prior to 1st
         January in the 20th Contract Year give notice to the Purchaser  that it
         desires to sell to a third  party  natural gas from the Gas Field which
         but for this  clause  it would be  required  to sell and the  Purchaser
         would be obliged to purchase in the  Contract  Years  numbered 21 to 26
         inclusive ("the Final Contract Years").

3.52     Except in Contract  Years 1 to 10 inclusive  (during  which period this
         clause 3.52 shall not apply) the  Purchaser  may after  receipt of such
         notice give notice to the Notifying  Producer  affirming this Agreement
         in respect of the Final  Contract  Years,  in which case this Agreement
         (so far as it is a  separate  agreement  with the  Notifying  Producer)
         shall continue in full force and effect  according to its terms and the
         notice given pursuant to Clause 3.51 shall be of no force or effect.

3.53     Forthwith upon receipt of any notice from a Notifying Producer given in
         Contract  Years 1 to 10 pursuant to clause 3.51,  or in any  subsequent
         Contract  Year if the  Purchaser  fails to give  notice to a  Notifying
         Producer  pursuant to Clause 3.52 within sixty (60) days after  receipt
         of that Producer's notice under Clause 3.51, then:-

         (a)      The Notifying Producer shall have no obligation to deliver any
                  Gas in the Final  Contract  Years and  Schedule A hereto shall
                  ipso facto be deemed to be amended by deleting all  references
                  to the  Final  Contract  Years  and  all  references  in  this
                  Agreement  to  Annual  Minimum  Quantities,   Monthly  Minimum
                  Quantities  and the like  shall in  respect  of the  Notifying
                  Producer be read down accordingly

         (b)      the Notifying Producer may sell to a third party the Gas which
                  it is no longer  obliged to  deliver to  the Purchaser  in the
                  Final Contract Years


<PAGE>

         (c)      the Dedicated Quantity  shall  be  reduced  by  the  Notifying
                  Producer's Ownership Percentage of 37.5 PJ, and

         (d)      in all other respects  this  Agreement  shall continue in full
                  force and effect.

         (e)      The Purchaser  may by notice to each  Producer  other than the
                  Notifying  Producer amend this Agreement (so far as it relates
                  to each such other  Producer)  in the same  respects  (mutatis
                  mutandis)  as provided in  paragraphs  (a) and (c) above,  and
                  paragraphs  (b)  and  (d)  above  shall  also  apply  (mutatis
                  mutandis) in respect of each such other Producer.

3.60     Failure of Delivery under the Palm Valley Agreement

3.61     The  Producers,  having  regard to the fact that  natural  gas is to be
         supplied  under both this  Agreement and the Palm Valley  Agreement for
         the  purpose  of  generating  electric  power for  public  consumption,
         jointly  acknowledge that the Purchaser requires continuous delivery of
         the  Gas  the  subject  of  each  such  Agreement  according  to  their
         respective terms.

3.62     If the Palm Valley  Agreement shall at any time be terminated by either
         the Purchaser or the Palm Valley  Producers then the Purchaser may give
         notice to the  Producers  jointly of such  termination  (a  "Schedule A
         Variation Notice") which shall specify that the Purchaser requires each
         Producer to supply to the  Purchaser  upon and subject to the terms and
         conditions  contained in this Agreement its Ownership Percentage of the
         whole or any part of the natural gas to which the Purchaser  would have
         become  entitled to delivery  under the Palm Valley  Agreement,  and in
         particular shall specify:-

         (a)      in Part A thereof in respect of each whole remaining  Contract
                  Year an  amended  Annual  Minimum  Quantity  being the  Annual
                  Minimum  Quantity  specified  in Schedule A  increased  by the
                  whole  or any part of the  relevant  Annual  Minimum  Quantity
                  specified in Schedule A to the Palm Valley  Agreement for that
                  Contract Year and;

         (b)      in Part B thereof in respect of each remaining  whole Month of
                  the  Contract  Year  current  at the time of such  notice,  an
                  amended  Monthly  Minimum  Quantity being the Monthly  Minimum
                  Quantity  applicable  under this  Agreement  increased  by the
                  whole or any part of the  relevant  Monthly  Minimum  Quantity
                  applicable under the Palm Valley Agreement; and

         (c)      in Part C thereof,  in respect of the period to the end of the
                  then current  Month,  the amount of  additional  Gas which the
                  Purchaser  requires to be delivered on a daily basis until the
                  end of such Month.

3.63     As from the date of receipt by  the Producers of a Schedule A Variation
         Notice:-

         (a)      Schedule A shall  forthwith be varied in the manner  specified
                  in Part A of such Notice with effect from the  commencement of
                  the next succeeding Contract Year;


<PAGE>

         (b)      the Monthly  Minimum  Quantity  applicable for each succeeding
                  Month of the current  Contract Year shall be forthwith  varied
                  in the manner  specified  in Part B of such Notice with effect
                  from the commencement of the next succeeding Month, and

         (c)      the Daily  Minimum  Quantity of Gas for each  remaining Day of
                  the current  Month shall be increased in the manner  specified
                  in  Part C of the  said  Notice  with  effect  from  the  next
                  succeeding day

         but subject always to clauses 3.66 and 3.67.

3.64     If from time to time or at any time  during the term of the Palm Valley
         Agreement  the  Palm  Valley  Producers  fail  to  deliver   contracted
         quantities  of Palm  Valley Gas or give notice to the  Purchaser  of an
         anticipated failure in delivery of contracted quantities, then provided
         the Purchaser has not in respect of such failure delivered a Schedule A
         Variation Notice the Purchaser may give notice to the Producers jointly
         under this Clause ("a Shortfall Notice") which shall specify:

         (a)      the nature  of the  delivery failure  or  anticipated  failure
                  under the Palm Valley Agreement;

         (b)      the  aggregate  quantity of Gas which the  Purchaser  requires
                  each Day to be delivered by the Producers  upon and subject to
                  the  terms  and  conditions  contained  in this  Agreement  in
                  substitution for Palm Valley Gas ("Shortfall Gas") and

         (c)      the period during which Shortfall Gas is likely to be required
                  by the Purchaser ("Shortfall Period").

3.65     Upon receipt of a Shortfall  Notice the Daily Minimum Quantity for each
         Day of the Shortfall  Period shall be ipso facto increased by the daily
         quantity of Shortfall Gas specified as aforesaid, but subject always to
         clause 3.66 hereof.

3.66     (a)      If the Producers are  or  will  be  unable  despite their best
                  endeavours  but having  regard to good oil field  practice  to
                  supply  upon and  subject to the terms and  conditions  herein
                  contained  any quantity of the  additional  Gas required to be
                  delivered  by a Schedule  A  Variation  Notice or a  Shortfall
                  Notice then they shall  forthwith  jointly give notice thereof
                  to the Purchaser and shall specify therein the extent to which
                  and period during which they expect to be unable to supply the
                  required quantities,  the reasons therefor, and the additional
                  Development  Work which in their opinion would be necessary in
                  order to meet the Purchaser's requirements.

         (b)      Upon receipt by the Purchaser of a  notice  given  pursuant to
                  paragraph (a) of this clause the Purchaser may either:

                  (i)      accept  the   Producers'   inability  to  supply  the
                           additional  Gas specified in which case paragraph (f)
                           of this clause shall apply, or

                  (ii)     require  the  Producers  jointly to proceed  with the
                           additional  Development  Work  specified  in the said
                           notice,  in which case  paragraph  (e) of this clause
                           shall apply, or

                  (iii)    refer to an  Independent  Expert the  question of the
                           Producers' inability to supply or the extent (if any)
                           of  the  Development   Work  necessary  to  meet  the
                           Purchaser's requirements.

         (c)      Upon any  reference  pursuant to  paragraph (b) of this clause
                  the Independent Expert shall certify as to:

                  (i)      whether the Producers ought in all the  circumstances
                           (including  without  limiting the generality  thereof
                           the capacity of the existing Gas Delivery  System and
                           their  obligations  under  other gas sales  contracts
                           entered into in  accordance  with this  Agreement) be
                           excused from their  respective  liabilities  for such
                           non-delivery or any part thereof and

                  (ii)     the nature and extent of the  additional  Development
                           Work (if any) which  would be  necessary  to meet the
                           Purchaser's requirements.

         (d)      Where  the  Independent   Expert   certifies  that  additional
                  Development   Work  is  necessary  to  meet  the   Purchaser's
                  requirements the Purchaser may either

                  (i)      require the  Producers  jointly to proceed  with such
                           additional  Development  Work in which case paragraph
                           (e) of this clause shall apply, or

                  (ii)     accept the  Producers'  inability to  supply in which
                           case paragraph (f) of this clause shall apply.

         (e)      Where  pursuant  to this  clause the  Purchaser  requires  the
                  Producers jointly to proceed with additional  Development Work
                  then PROVIDED the parties first agree on arrangements  for the
                  recoupment  by  each  Producer  of  some  or all of the  costs
                  thereof,  and upon and  subject  to the terms so  agreed,  the
                  Producers  jointly  undertake  that they will proceed with all
                  expedition  to  carry  out the  same  but in  absence  of such
                  agreement  as  aforesaid  paragraph  (f) of this clause  shall
                  apply.

         (f)      Where and to the  extent  that  pursuant  to this  clause  the
                  Purchaser accepts or an Independent  Expert certifies that the
                  Producers are unable to supply any part of the  additional Gas
                  requested  then no  Producer  shall  be  deemed  to have  made
                  default in delivery of such Gas and the Daily Minimum Quantity
                  and Monthly Minimum  Quantity for the period in question shall
                  be reduced accordingly.

3.67     Notwithstanding  the  foregoing  provisions  of  this  clause  3.60  no
         Producer  shall be obliged to supply Gas  pursuant to clauses  3.62 and
         3.63 to the extent that such supply would reduce the Proven Reserves of
         the Gas  Field  below the  Warranted  Quantities  unless  and until the
         Purchaser  shall first agree in writing that the  Warranted  Quantities
         shall be reduced to the resulting Proven Reserves.

         (a)      If the  Purchaser has paid for a quantity not taken in a Month
                  ("the Debit Month") the Purchaser may in any subsequent  Month
                  ("Credit  Months")  after it has  taken  the  Monthly  Minimum
                  Quantity as reduced in accordance  with clause 3.21(b) for the
                  relevant  Month take free of charge  except for payment of the
                  difference if any in the Contract Price in the relevant Credit
                  Month and Debit  Month a quantity of Gas  (hereinafter  called
                  "Make-up  Gas") up to the  quantity  so paid for in the  Debit
                  Month  PROVIDED  always that Make-up Gas in respect of any one
                  Debit Month shall not be taken  before  available  balances in
                  all previous Debit Months have been made taken.

         (b)      Notwithstanding clause 3.10 but  subject to clauses  10.20 and
                  10.30, this Agreement shall for purposes of this clause remain
                  on foot  beyond 25 years for a period of not more than 5 years
                  but not beyond delivery of the Dedicated Quantity,  until such
                  time as the Purchaser shall have taken delivery of all Make-up
                  Gas to which it is entitled,  and where  (but  for  this  sub-
                  clause)  this Agreement would otherwise be at an end paragraph
                  (a) shall apply on the  basis that the Purchaser  shall in any
                  Month be entitled  to take Make-up Gas notwithstanding that no
                  Minimum  Monthly  Quantity  applies  for  the Month,  PROVIDED
                  ALWAYS that the Purchaser's rights under this sub-clause shall
                  be suspended for any period during which natural  gas from the
                  Gas Field  is  not  being  supplied  either  to the  Purchaser
                  (pursuant to a renewal or replacement agreement)  or any other
                  party but the period of 5 years  referred to in this paragraph
                  (b) shall be extended by the period of any such suspension.

         (c)      To the extent, if any, to which the Contract Price in a Credit
                  Month is to be taken into account  under this clause then such
                  Contract Price shall be the price applicable in that Month for
                  Probable  Gas,  or which  would have been  applicable  in that
                  Month if the  differential  prices for Probably Gas and Excess
                  Gas continued to apply after Contract Year 21.

4.30     Refund if Gas Field Depleted

         If at any  time  the  report  of  the  independent  reservoir  engineer
         pursuant  to clause 2.22 or any other  report of a  reservoir  engineer
         acceptable to the Purchaser and the Producers  establishes  that Proven
         Reserves in the Gas Field together with Proven Reserves in an Alternate
         Gas Field (if any) are less than those  necessary  for the  delivery of
         the  remaining  Gas  which  is  required  to be  delivered  under  this
         Agreement (that is, less than the lesser of:-


<PAGE>

         (a)      the  balance  of  the   Dedicated  Quantity  remaining  to  be
                  delivered or

         (b)      the aggregate of the remaining  Annual Minimum Quantities plus
                  Make-up Gas)

         then the  Purchaser  shall be entitled to have  delivered  to it to the
         extent to the deficiency of Proven Reserves  Make-up Gas in priority to
         any Annual Minimum  Quantities.  To the extent that it appears that the
         Purchaser  will not  thereby  receive  any  quantity  of Make-up  Gas a
         Producer shall forthwith upon demand repay to the Purchaser in cash all
         payments made to it in accordance  with paragraph (c) of clause 3.21 in
         respect of such amount  plus  interest  on all such  payments  from the
         respective dates of payment at the same rate as Recovery Interest.

         For the purposes of this clause:

         (i)      "Alternate  Gas Field"  means a gas field  (other than the Gas
                  Field)  from which the  Producers  shall be  entitled  and are
                  capable of supplying Gas for the purposes of this Agreement.

         (ii)     "Proven Reserves in an Alternate Gas Field" means the quantity
                  of Proven Reserves in an Alternate Gas Field which are at that
                  time  dedicated and  committed  for the  exclusive  purpose of
                  supplying Gas under this Agreement.

         (iii)    To the extent that any payments by the Purchaser  under clause
                  3.21(c) have been made at the  Contract  Price  applicable  to
                  Probable Gas all  repayments  by a Producer  under this clause
                  shall be calculated as if the Purchaser had made such payments
                  at the Contract Price applicable to Excess Gas.

4.40     Consumer Price Index

4.41     In the event that the CPI shall be discontinued or modified the parties
         shall request the Australian Bureau of Statistics to provide figures or
         indices which shall give an  equivalent  comparison to that provided by
         the CPI.

4.42     If the  parties  are  unable to obtain  from the  Australian  Bureau of
         Statistics  figures or indices which given an equivalent  comparison to
         that  provided  by the said  index  and are  unable  to  agree  between
         themselves as to such figures or indices  either the Producers  jointly
         or the  Purchaser  may request the  President for the time being of the
         Institute  of  Chartered  Accountants  in  Australia  or his nominee to
         provide at each review date figures or indices which give an equivalent
         comparison to that  contemplated by the CPI and such figures or indices
         shall then for the purposes of this Agreement be deemed to be the CPI.

4.50     Increase in Commonwealth Imposts

         (a)      For the purpose of this Clause the Base Level of Imposts means
                  the aggregate of N. T. Imposts and  Commonwealth Imposts as at
                  the Development Date.


<PAGE>

         (b)      If any  increase  of  Commonwealth  Imposts  has the effect of
                  increasing  the  aggregate  of N.T.  Imposts and  Commonwealth
                  Imposts to 150% or more of the Base Level of Imposts then each
                  of the Producers shall be entitled to recover as Imposts Price
                  in respect of Gas  delivered  by it any part of that  increase
                  and the  amount of any  subsequent  increase  of  Commonwealth
                  Imposts  which has the effect of  increasing  the aggregate of
                  N.T. Imposts and Commonwealth  Imposts beyond 150% of the Base
                  Level of Imposts.

4.60     Increase in N.T. Imposts

4.61     (a)      For the purpose of this clause the Base Level of Imposts means
                  the aggregate of N.T.  Imposts and  Commonwealth Imposts as at
                  the later of the Development Date or the Date of Last Review.

         (b)      If any increase or increases of N.T. Imposts has the effect of
                  increasing  the  aggregate  of N.T.  Imposts and  Commonwealth
                  Imposts to 110% or more of the Base Level of Imposts then each
                  of the Producers shall be entitled to recover as Imposts Price
                  in respect of Gas  delivered by it the whole of such  increase
                  or increases of N.T.  Imposts which since the Development Date
                  or the Date of Last Review (whichever is applicable)  together
                  shall have had the effect of so  increasing  the  aggregate of
                  the N.T.  Imposts and the Commonwealth  imposts.  The "Date of
                  Last  Review"  shall  mean the date on which a  Producer  last
                  became  entitled to recover  increases in imposts  pursuant to

5.00     ADJUSTMENT OF GAS TO SPECIFICATION

5.10     Rights of Purchaser

         5.11     Without  prejudice  to any  other  rights or  remedies  of the
                  Purchaser against a Producer for losses incurred, in the event
                  that Gas tendered  for  delivery  hereunder by any Producer (a
                  "defaulting Producer") fails to meet any of the specifications
                  set forth in Schedule B:-

                  (a)      The  Purchaser  shall  have the  right to  refuse  to
                           accept   further   deliveries   from  the  defaulting
                           Producer  until such failure is  rectified,  and that
                           Producer   shall  become   liable  for  the  cost  of
                           alternative  fuel  supply in  accordance  with clause
                           3.40.  The  Purchaser  shall  forthwith  notify  such
                           refusal by  telephone  to the  Producers  jointly and
                           shall confirm the same by written notification within
                           24 hours, specifying the nature of the deficiency.

                  (b)      The  Purchaser may  knowingly or  unknowingly  accept
                           such Gas and may install,  operate and maintain  such
                           facilities  as may be  required  to cause such Gas to
                           meet such  specifications in which case the Purchaser
                           shall have the right to recover  from the  defaulting
                           Producer all costs incidental thereto, including fuel
                           supply damages,  depreciation,  overhead and costs of
                           capital  all of  which  may  be  deducted  from  sums
                           payable by the Purchaser to the  defaulting  Producer
                           hereunder.

         5.12     Without  prejudice  to any  other  rights or  remedies  of the
                  Purchaser against the defaulting  Producer for losses incurred
                  in the  event  that Gas  supplied  fails to  achieve a minimum
                  Gross Heating Value of 36MJ/m3,  the defaulting Producer shall
                  compensate the Purchaser for all  additional  costs payable by
                  the Purchaser  associated  with the movement of the additional
                  volumes of Gas  through the  Pipeline  required to achieve the
                  energy  equivalence of Gas rated at 36MJ/m3 over the period of
                  delivery  of  the  specification   breach.  Any  statement  or
                  calculation  of such  costs  by the  Purchaser  shall be prima
                  facie evidence thereof.

         5.13     It shall be no  defence  to any  action by the  Purchaser  for
                  recovery of costs  pursuant to clauses  5.11 and 5.12 that the
                  Purchaser  shall not have  personally  incurred  such costs or
                  shall be entitled to recoup such costs from the Consumers.

5.20     Removal of Constituents

         So long as the Gas remains within specification,  the Producers jointly
         may, prior to delivery thereof or otherwise as the Purchaser may agree,
         submit  such Gas to any process the  Producers  jointly  desire for the
         removal of constituents or elements  therein other than for the removal
         of methane (except where methane removal is an unavoidable  consequence
         of the removal of other  constituents).  Such separate  constituents or
         elements will remain the property of the  Producers in their  Ownership
         Percentages.

5.30     Quality Tests

         The  Purchaser and the  Producers  jointly shall agree upon  reasonable
         methods and  procedures  and determine the  instruments  to be used for
         making  tests to determine  whether Gas conforms to the  specifications
         set forth in Schedule B.

         If the parties are unable to agree upon such  procedures  any party may
         refer the question for determination by an Independent Expert.

6.16     Correction

         If at any time,  any of the  measuring  equipment is found to be out of
         service or  registering  inaccurately,  it shall be adjusted at once to
         read as accurately as possible and the readings of such equipment shall
         be adjusted to zero error for a period definitely known or agreed upon,
         or if not known or agreed  upon,  for  period of  sixteen  (16) days or
         one-half  (1/2) of the elapsed  time since the last test,  whichever is
         shorter.  The  measurement  during  the  appropriate  period  shall  be
         determined  by the  Pipeline  Operator  on the  basis of the best  data
         available using the first of the following methods which is feasible:

         (a)      by using the data recorded by any check measuring equipment if
                  installed and accurately registering; or

         (b)      by making the appropriate correction if the deviation from the
                  accurate  reading  is  ascertainable  by  calibration  test or
                  mathematical calculation; or

         (c)      by estimating  based upon receipts or deliveries under similar
                  conditions  during a period when the equipment was registering
                  accurately.

6.17     Additional Tests

         (a)      The  Producers   jointly  may  require   additional  tests  at
                  reasonable intervals.

         (b)      If upon testing,  the deviation  from the accurate  reading is
                  found to be less than two percent (2%),  each  Producer  shall
                  bear its Ownership Percentage of the expense of the additional
                  test.

6.18     Inspection of Equipment and Records

         (a)      Each party shall have the right at all times to have access to
                  the Custody Transfer Area and to inspect  measuring  equipment
                  installed or furnished by the other.

         (b)      Each  party  shall  have the right to  inspect  the charts and
                  other  measurement  or test  data of the  other  at all  times
                  during normal business hours.

         (c)      The reading,  calibration and adjustment of such equipment and
                  changing  of the  charts  shall  be done  only  by the  person
                  installing or furnishing  the same and each Producer  shall be
                  entitled  to be  present  at such time but shall be subject to
                  all  reasonable  requirements  of the Pipeline  Operator  with
                  regard to the  security of the Custody  Transfer  Area and the
                  equipment.

6.19     Purchaser's Agent and the Producer's Representative

         For the purposes of clause 6.00 the  Purchaser may appoint the Pipeline
         Operator  or any other  person as its  agent to  perform  or act in its
         stead and any Producer may appoint the  Representative  as its agent to
         perform or act in its stead.

6.20     Method of Measurement

         All  measurements,  calculations  and  procedures  used in  determining
         volume, except for the correction for deviation from Boyle's Law, shall
         be  made in  accordance  with  the  instructions  contained  in the Gas
         Measurement  Committee Report Number 3 of the American Gas Association,
         dated April 1955,  together  with all presently  existing  supplements,
         amendments and appendices to the said Report.  Such  instructions to be
         converted  where  necessary for  compliance  with  Australian  Standard
         AS1000-1979   "The   International   System  of  Units   (SI)  and  Its
         Application",   the  Commonwealth   "Weights  and  Measures   (National
         Standards) Act 1960-1966" and Regulations thereunder and the Australian
         Gas Association  publication  "Metric Units and Conversion  Factors For
         Use In the Australian Gas Industry".  The correction for deviation from
         Boyle's  Law  shall  be  determined  from the  data  contained  in "PAR
         Research Project NX-19" as published by the American Gas Association in
         1962,  or any revision  thereof  acceptable  to the  Purchaser  and the
         Producers jointly.

6.30     Unit of Measurement

         The unit of volume for purposes of measurement hereunder,  shall be one
         103m3 of Gas and be  expressed to the nearest  one-tenth  103m3 or such
         other unit of volume agreed to by Purchaser and the Producers jointly.

6.40     Atmospheric Pressure

         For the purpose of measurement atmospheric pressure shall be determined
         by a  recognised  formula  applied to the  nearest one  hundredth  of a
         kilopascal absolute (.01 kPa) and deemed to be a constant.

6.50     Flowing Temperature

         The  flowing  temperature  of Gas  shall be  determined  by means of an
         approved recording thermometer of standard make. The arithmetic mean of
         all  readings  each day shall be deemed to be the Gas  temperature  and
         shall be used in computing volume.

6.60     Determination of Gas Characteristics

         The gas characteristics  including,  without limiting the generality of
         the foregoing,  Gross Heating  Value,  relative  density,  nitrogen and
         carbon  dioxide  content  of gas  shall  be  determined  by  continuous
         recording equipment or by laboratory equipment. If continuous recording
         equipment is used the  arithmetic  mean of all  recordings for each day
         will be used to  determine  gas  characteristics.  If spot  samples are
         taken or a spot sampler is used, gas characteristics will be determined
         from  the  analysis  of the  samples  using  laboratory  equipment  and
         recognised analytical methods.

10.20    Default by Producers

         If any one or more of the following events occurs, namely:

         (a)      if any order is made for the  liquidation  of a Producer  or a
                  Producer  institutes any proceedings or  arrangements  for its
                  liquidation  in whole or in part or for the  appointment  of a
                  receiver or any  receiver is appointed of any of its assets or
                  a Producer  is unable to pay its debts  within the  meaning of
                  that expression in the Companies  legislation of the Territory
                  and  as a  result  of  any  of  the  foregoing  the  Purchaser
                  reasonably believes that the supply of Gas by that Producer to
                  the  Purchaser is placed in jeopardy or that the Purchaser may
                  be  unable  to  obtain  a good  discharge  in  respect  of its
                  obligations;

         (b)      if a Producer  make default in the due  performance  of any of
                  its substantial  covenants or obligations under this Agreement
                  (not being a covenant or obligation of the kind referred to in
                  sub-clause  (c) of this  clause)  and if a  Producer  fails to
                  remedy or to commence and diligently continue in good faith to
                  remedy that  default  within a  reasonable  time after  notice
                  specifying the default is given to the Producer; or

         (c)      if a Producer  makes  default in the due payment of any moneys
                  payable hereunder and any such default remains  unremedied for
                  a period  exceeding  thirty days after notice  specifying  the
                  default is given to the Producer;

         then and in any such events the  Purchaser  may by notice in writing to
         the  relevant  Producer  (so far as the  separate  Agreement  with that
         Producer is concerned):-

                  (i)      Suspend its  obligations to make  payments under this
                           Agreement until the default is remedied; or

                  (ii)     Terminate  such  separate  Agreement   whereupon  the
                           Purchaser  shall  have no further  liability  to that
                           Producer  hereunder  and shall be entitled to recover
                           from  that  Producer  as and  by  way  of  liquidated
                           damages  the  net  present   value   (determined   as
                           hereinafter provided) of the liquidated damages which
                           would be recoverable  from that Producer  pursuant to
                           clause 3.43 if that Producer made default in delivery
                           of that  quantity of  Obligation  Gas  required to be
                           delivered   by  that   Producer   from  the  date  of
                           termination by the Purchaser as aforesaid to the date
                           on  which  this   Agreement   would   otherwise  have
                           terminated ("Date of Expiry").  The net present value
                           of such damages shall be determined by:


<PAGE>

                           (A)      ascertaining  the  amount of the  liquidated
                                    damages which would be recoverable from that
                                    Producer in respect of the Month immediately
                                    preceding  the date of  termination  if that
                                    Producer  had made  default in  delivery  of
                                    133%  of  its  Ownership  Percentage  of the
                                    Monthly Minimum Quantity during that month;

                           (B)      assuming  that the same amount of liquidated
                                    damages  as in  paragraph  (A)  above  would
                                    apply in respect of each Month from the date
                                    of termination to the Date of Expiry;

                           (C)      discounting  the   amounts  referred  to  in
                                    paragraph (B)  above to present value at the
                                    rate of 8 percent per annum.

                           Termination  of this  Agreement  with  respect to any
                           Producer shall be without  prejudice to the rights of
                           any party accruing prior to termination,  but subject
                           thereto and to the  provisions  of this  clause,  the
                           Purchaser  shall  not  have  and  shall  not make any
                           further or other  claims upon the  relevant  Producer
                           arising out of or in any way in  connection  with any
                           default  by  the  Producer  or  termination  of  this
                           Agreement as aforesaid.  Upon the termination of this
                           Agreement as aforesaid no further  liquidated damages
                           under clause 3.43 shall accrue.

10.30    Default by Purchaser

         If the  Purchaser  in  relation  to any  Producer  is in default in the
         observance or  performance  of any  substantial  covenant or obligation
         under this Agreement and such default shall continue for a period of 90
         days after written notice  specifying the default shall have been given
         to the  Purchaser by such  Producer then that Producer may by notice in
         writing to the Purchaser (so far as the separate  Agreement between the
         Purchaser and that Producer is concerned):

         (i)      Suspend   deliveries  of  Gas  hereunder   provided  that  the
                  Purchaser  shall remain liable to pay that Producer the amount
                  due to it for Monthly Minimum  Quantities  which will not give
                  any entitlement to Make-up Gas; and/or

         (ii)     Terminate such separate Agreement.

         In the event that a Producer  terminates  such  separate  Agreement  as
         aforesaid  the  Purchaser  shall pay to that  Producer as and by way of
         liquidated damages its Ownership Percentage of the net present value of
         the Base Price for the aggregate Annual Minimum Quantities remaining to
         be delivered  under this Agreement as at the date of  termination.  The
         net present value as aforesaid shall be determined by:

                  (A)      Ascertaining  the Base Price  which  applied or would
                           have   applied   under  this   Agreement   using  the
                           assumptions set out in (B) below in each Quarter from
                           the start of the Contract  Year in which  termination
                           occurs until the aggregate Annual Minimum  Quantities
                           remaining to be delivered  under this Agreement would
                           have been delivered;


<PAGE>

                  (B)      The   actual   impact  on  the  Base   Price  of  CPI
                           Escalation,  Mega CPI Escalation and Fuel  Escalation
                           is to be averaged on an annual  basis over  whichever
                           of the following  periods prior to termination is the
                           longer namely:

                           (I)      three years; and

                           (II) the period since the Date of Initial Delivery.

                  (C)      Assuming the Base Price  ascertained in paragraph (A)
                           above for the four  Quarters in each of the  relevant
                           Contract  Years and  dividing the sum thereof by four
                           to derive the average  Base Price  applicable  to the
                           respective Contract Years.

                  (D)      Multiplying the Annual Minimum  Quantities  remaining
                           to be delivered under this Agreement from the date of
                           termination  by  the  average  Base  Price  for  each
                           relevant Contract Year to derive the price payable by
                           the Purchaser in respect of each such Contract Year.

                  (E)      Discounting  each  of  the  amounts  referred  to  in
                           paragraph  (D) above to  present  value as a mid year
                           stream at the rate of 7 percent  per annum  above the
                           CPI for the relevant  Contract Year, and  aggregating
                           the resulting amounts.

10.40    Waivers not to affect other defaults

         No waivers by any party of any one or more defaults by any other in the
         performance of any provisions shall operate or be construed as a waiver
         of any other default whether of a like or of a different character, and
         whether occurring before or after such waiver.

12.10    When Consent Required

         (a)      No assignment by a Producer of this Agreement or of its rights
                  hereunder  shall be of any effect  whatsoever  unless with the
                  written  consent of the  Purchaser  which consent shall not be
                  unreasonably  withheld  in  the  case  of  a  financially  and
                  technically   competent  assignee  PROVIDED  ALWAYS  that  the
                  assignee  shall  covenant in writing with the  Purchaser to be
                  bound by all the terms and conditions of this Agreement so far
                  as they apply to the assignor.

                  the written  consent of each of the  Producers  which  consent
                  shall  not  be   unreasonably   withheld  in  the  case  of  a
                  financially and technically competent assignee PROVIDED ALWAYS
                  that  the  assignee   shall  covenant  in  writing  with  each

TABLE III
NOTES

         1.       This table is derived in the case of:

                  (a)      Coln 3 to Coln 6 from Table I; and

                  (b)      Coln's 7 and 9 from Table II.

         2.       Coln's 3, 5 and 9,  respectively,  are derived by applying the
                  Quarterly CPI (Coln 5 Table I), MEGA (Coln 6 Table I) and Fuel
                  (Coln 4 Table II) escalators to that portion of the Base Price
                  (including  any previous  such  escalations)  as apply to that
                  escalator.  The result being the annual  increment in the Base
                  Price attributable to that escalator.  For the purpose of this
                  calculation the respective portions are:

                  (a)      in the June Quarter 1985:

                           (i)      $0.375 for CPI Escalation
                           (ii)     $1.125 for Mega Escalation
                           (iii)    $1.500 for Fuel Escalation

                  (b)      In latter quarters the June 1985 Base plus escalation
                           to the quarter of concern.

         (c)      The CPI (as  herein  defined)  for the relevant financial year
                  expressed as a percentage.

4.       DERIVATIONS FROM DATA

         Step 1:  Aggregation

         Add  each of (a) and (b) in 3 above  to  produce  a three  State  total
         (hereinafter A and B respectively).


<PAGE>

         Step 2:  Fuel Cost Ratio

         The Fuel Cost Ratio (F) for the purpose of  calculating  the fuel price
         escalator shall be 0.24.

         Step 3:  Average Sale Price

         Derive  the  average  sale  price  of  electricity  during  the year in
         cents/kWh  by dividing  total income from all sales (See 3(a) above) by
         consumption (see 3(b) above).

                                      G = A

                              H = __________ x 100

                                     Gt-1

                  where subscript:  t refers to the present year
                                    t-1 refers to the previous year

         Step 5:  CPI - Sale Price Differential

         Derive the difference in  the  annual  percentage  movement in the sale
         price of  electricity  (see Step 4 above)  and  the  CPI (K)  (see 3(c)
         above).

                                    K = H - J

              where J is the Annual Percentage Movement in the CPI

                                 CPIt - CPIt-1
                             J = ____________ x 100

                  contract is a contract by way of gaming or wagering; or

         (u)      set aside,  appropriate or provide out of or from the Fund any

                  contract, the engaging in the transaction or the other dealing
                  is  a  proper  exercise  by  the  Trustee  of  its  powers  or
                  discretions  under this deed, or to see to the  application or
                  use  of  any  money,  rights,   property  or  assets  paid  or

         (b)      In  particular   but  without   limiting  the   generality  of
                  sub-clause (a), no person lending or advancing money or giving
                  credit  or  financial  accommodation  to the  Trustee  need be
                  concerned   to  see  that  the  money,   credit  or  financial
                  accommodation  is  required  or  that no  more  money  than is
                  required is borrowed or raised or to see to the application or
                  use of the money borrowed or raised.

8.8      Each power and  discretion  conferred  on the  Trustee  under this Part
         shall be an  independent  head of power or discretion  and shall not be
         limited  or read  down by  reference  to any  other  head of  power  or
         discretion  under this Part, and may be exercised as the Trustee thinks
         fit in its  absolute  and  uncontrolled  discretion  as if it were  the
         absolute beneficial owner of the Fund, and the Trustee shall have power
         to do all things  incidental to the effective  exercise of any power or
         discretion  conferred  on the  Trustee  under this deed and in addition
         shall have all powers and discretions  conferred on Trustees by statute
         or otherwise by law.

8.9      (a)      A director of the Trustee may be or become a director or other

                  unit holder  (including  the  Special Unit  holder)  that is a
                  corporation.  Any such director  shall  not be  accountable to
                  the Fund or to the unit  holders  (including  the Special Unit
                  holder) for any remuneration or other benefits received by him
                  as a  director  or  officer  of or from  his  interest  in the
                  corporation  or the unit holder  (including  the Special  Unit
                  holder) that is a corporation.


<PAGE>

         (b)      No contract entered into or other transaction engaged in by or
                  on behalf of the Trustee in which a director of the Trustee is
                  in any way, whether  directly or indirectly,  interested shall
                  be avoided nor shall a director  of the Trustee be liable,  by
                  reason of  holding  his office or the  fiduciary  relationship
                  thereby  established,  to  account  to the Fund or to the unit
                  holders  (including  the Special  Unit  holder) for any profit
                  arising from such contracts or other transactions.

         (c)      A director of the Trustee may vote in respect of any  contract
                  or other transaction or proposed contract or other transaction
                  in which he is in any way,  whether  directly  or  indirectly,
                  interested  or in respect of any matter  arising out of such a
                  contract or other  transaction  or proposed  contract or other
                  transaction,  and he may sign or  countersign  a  contract  or
                  other  documents  to which the seal of the  Trustee is affixed
                  notwithstanding  that he is in any way,  whether  directly  or
                  indirectly,  interested in that contract or other  document or
                  in the  matter  to  which  that  contract  or  other  document
                  relates.

                  unit holders shall within 30 days by an  instrument  signed by
                  or on behalf of unit holders holding between them at least 75%
                  of the units issued in the Fund at the  relevant  time appoint
                  any  person or  persons  other  than a unit  holder  (the "new
                  Trustee") to be Trustee in place of the old  Trustee,  and the
                  old Trustee  shall pay or transfer the Fund to the new Trustee
                  and shall  for the  purpose  execute  and  deliver  to the new
                  Trustee all deeds,  transfers,  conveyances,  assignments  and

<PAGE>

         (c)      The new Trustee  shall execute and deliver to the unit holders
                  (including the Special Unit holder) a deed and  declaration of
                  trust in which the new Trustee  undertakes  for the benefit of
                  the unit holders  (including  the Special Unit holder) to take
                  the office of Trustee and perform or discharge the obligations
                  and liabilities of the Trustee under this deed.

12.5     Notwithstanding  any  other  provision  of this  deed or any  provision
         included  or deemed to be included  therein  (whether  expressly  or by
         implication),  the entire liability of each unit holder  (including the
         Special Unit holder) will be limited to the subscription price (if any)
         payable by that unit holder in respect of any units  subscribed  for by
         it  hereunder  and no unit holder  (including  the Special Unit holder)
         shall have any liability to make any further  contribution  to the Fund
         or payment to the Trustee in respect thereof. No unit holder (including
         the Special Unit holder)  shall be under any  obligation  personally to
         indemnify  the Trustee or any creditor of the Trustee in respect of any
         of the liabilities (actual,  contingent or otherwise and whether due to
         any  deficiency or not) of the Trustee in relation to,  arising from or
         in connection  with the Fund,  whether arising from or by reason of the
         holding of any unit or any  relationship  with the Trustee arising from
         any such holding.  Any such liabilities are hereby expressly  excluded.
         The only rights, if any, of indemnity of the Trustee and the respective
         creditors shall be limited to having  recourse to the Fund.  Nothing in
         this deed shall constitute  either the Trustee as the agent of any unit
         holder  (including the Special Unit holder) nor create any relationship
         between any unit holder  (including the Special Unit holder) on the one
         hand and the Trustee  (other  than as trustee) on the other.  Creditors
         and other persons having any dealing with the Trustee hereby  expressly
         disclaim any right or  entitlement  to have recourse to any unit holder


<PAGE>

         (including  the Special Unit holder) in respect of any  liabilities  of
         the  Trust or the  Trustee.  Without  limiting  the  generality  of the
         provisions  of this  clause,  it is  recorded  that  the  unit  holders
         (including  the Special Unit  holder)  shall be entitled to rely on the
         provisions  of this  clause  also in cases  where any  liabilities  are
         incurred  as a result  of any  direction  or  request  of unit  holders
         (including the Special Unit holder).

12.6     The Trustee shall be paid such remuneration for performing its services
         and functions  under this deed as is from time to time determined by an
         instrument  signed by or on behalf of unit holders holding between them
         at least 75% of the units issued in the Fund at the  relevant  time but
         until otherwise determined as aforesaid no remuneration will be paid to
         the Trustee.

         fit.


10.      Return Ceiling

W H E R E A S:

A.       The Palm Valley Producers have negotiated the terms of an agreement for
         the sale by them severally to Gasgo Pty. Limited ("the Purchaser") of a
         quantity of Gas from the Palm Valley Field for transmission through the
         Trunk Pipeline leased by the Pipeline Trust for  consumption  primarily
         by NTEC in electricity generation in Darwin.

B.       The Purchaser  has  requested  the Palm Valley  Producers to relinquish
         part of their  entitlement  to sell Gas to the Purchaser with a view to
         permitting  the Mereenie  Producers to enter into an agreement with the
         Purchaser for the sale of Gas and in the  circumstances the Palm Valley
         Producers  felt  compelled to agree with that request and the agreement
         between the Palm Valley Producers and the Purchaser for the sale of Gas
         ("the Palm Valley Gas Purchase Agreement") reflects that agreement.

C.       In consideration  of the Palm Valley  Producers  agreeing to relinquish
         part of their entitlement to sell Gas to the Purchaser,  the respective
         Mereenie   Producers  have  agreed  with  the  respective  Palm  Valley
         Producers  as  provided  in Clause 2 hereof and to  participate  in the
         Pipeline Benefits in the manner provided in Clause 3 hereof.

D.       In consequence of the agreement by the Palm Valley  Producers  referred
         to in Recital B hereof,  the  Purchaser  has entered  into an agreement
         ("the Mereenie Gas Purchase Agreement") with the Mereenie Producers for
         the purchase of certain quantities of Gas from the Mereenie Field.

E.       The  Northern  Territory  Government  has agreed with the  Producers to
         sponsor the  oversizing of the Trunk  Pipeline  between Palm Valley and
         Matarauka and the construction of the Mereenie Spur Line.


<PAGE>

                            INDEMNIFICATION AGREEMENT


         THIS AGREEMENT is made on this ____ day of  ____________,  ____ between
Magellan  Petroleum  Corporation,  a Delaware  corporation  ("Corporation")  and
_______________ ("Agent").

                              W I T N E S S E T H:

         WHEREAS,  Agent is a director and/or officer of Corporation and in such
capacity is performing a valuable service for Corporation; and

         WHEREAS,  Corporation's  Certificate of Incorporation  provides for the
indemnification of the officers,  directors, agents and employees of Corporation
to the maximum extent  authorized by the Delaware General  Corporation  Laws, as
amended to date (the "State Statutes"); and

         WHEREAS,  the Certificate of  Incorporation  contemplates  and requires
that  contracts  be entered  into  between  Corporation  and its  directors  and
officers with respect to the advance of expenses and indemnification; and

         WHEREAS,  Corporation has purchased and presently maintains a policy or
policies of Directors  and Officers  Liability  Insurance  ("D & O  Insurance"),
covering certain liabilities which may be incurred by its directors and officers
in the performance of their services for Corporation; and

         WHEREAS,  Corporation  desires to hold harmless and indemnify  Agent to
the full extent authorized or permitted by the provisions of the State Statutes,
or by any  amendment  thereof  or  other  statutory  provisions  authorizing  or
permitting such indemnification which may be adopted hereafter; and

         WHEREAS,  Corporation  has entered into this  Agreement and assumed the
obligations  imposed on Corporation  hereby in order to induce Agent to continue
as a director of Corporation,  and acknowledges  that Agent is relying upon this
Agreement in continuing in such capacity; and

         WHEREAS,  on August 19, 1987,  Corporation's  Board of Directors  first
authorized  Corporation  to  enter  into  this  Indemnification  Agreement  with
Corporation's directors and/or officers; and

         WHEREAS, on ________ ___, ____, this agreement was entered into between
Corporation and Agent; and

         WHEREAS,  since  the  execution  of  this  Indemnification   Agreement,
Corporation has purchased  additional D & O Insurance  coverage and other events
in the development of Corporation have occurred, and


<PAGE>



         WHEREAS,  Corporation  now seeks to confirm,  update and  restate  this
Indemnification Agreement.

         NOW,  THEREFORE,  in  consideration of Agent's  continued  service as a
director  and/or  officer  after the date  hereof the  parties  hereto  agree as
follows:

         1.       Maintenance of Insurance and Self Insurance.

                  (a) Corporation  represents that it presently has in force and
effect policies of D & O Insurance in insurance companies and amounts as follows
(the "Insurance Policies").

   Insurer              Policy No.            Amount              Deductible












Subject only to the provisions of Section l(b) hereof, Corporation hereby agrees
that,  so long as Agent  shall  continue  to serve as a  director  or officer of
Corporation  (or shall  continue  at the  request of  Corporation  to serve as a
director, officer, employee or agent of another corporation,  partnership, joint
venture,  trust or other  enterprise)  and  thereafter so long as Agent shall be
subject to any possible claim or threatened,  pending or completed action,  suit
or proceeding,  whether civil,  criminal or  investigative by reason of the fact
that  Agent was a  director  of  Corporation  (or  served  in any of said  other
capacities), Corporation will purchase and maintain in effect for the benefit of
Agent one or more  valid,  binding and  enforceable  policy or policies of D & O
Insurance  providing,  in all  respects,  coverage at least  comparable  to that
presently provided pursuant to the Insurance Policies.

                  (b) Corporation  shall not be required to maintain said policy
or policies of D & O Insurance  in effect if said  insurance  is not  reasonably
available or if, in the  reasonable  business  judgment of the then directors of
Corporation,  either (i) the premium cost for such  insurance  is  substantially
disproportionate to the amount of coverage or (ii) the coverage provided by such
insurance is so limited by exclusions  that there is  insufficient  benefit from
such insurance.

                  (c) In the event Corporation does not purchase and maintain in
effect said policy or policies of D & O Insurance  pursuant to the provisions of
Section 1(b) hereof,  Corporation agrees to hold harmless and indemnify Agent to
the full extent of the coverage which would otherwise have been provided for the
benefit of Agent pursuant to the Insurance Policies.


<PAGE>


         2.  Additional  Indemnity.  Subject only to the exclusions set forth in
Section  3 hereof,  Corporation  hereby  further  agrees  to hold  harmless  and
indemnify Agent:

                  (a) Against any and all expenses (including  attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by Agent in connection with any threatened,  pending or completed action,  suit,
claim,  counterclaim or proceeding,  whether civil, criminal,  administrative or
investigative  (including an action by or in the right of  Corporation) to which
Agent is,  was or at any time  becomes a party,  or is  threatened  to be made a
party,  by  reason  of the fact  that  Agent  is,  was or at any time  becomes a
director or officer of  Corporation,  or is or was serving or at any time serves
at the  request of  Corporation  as a  director,  officer,  employee or agent of
another  corporation,  partnership,  joint  venture,  trust or other  enterprise
(collectively,  "other  entity" or "another  entity").  Each such  indemnifiable
event,  subject to the  limitations  of Section 3 hereof,  shall be  hereinafter
referred to as a "Claim."

                  (b)  Otherwise  to the  fullest  extent as may be  provided to
Agent by Corporation  under the provisions of the  Certificate of  Incorporation
and the By-Laws of Corporation and the State Statutes,  as they now or hereafter
may exist.

         3.       Limitations on Additional Indemnity.  No indemnity pursuant to
Section 2 hereof shall be paid by Corporation:

                  (a)  except  to the  extent  the  aggregate  of  losses  to be
indemnified  thereunder  exceed the sum of $1,000 plus the amount of such losses
for which the Agent is indemnified  either pursuant to Sections 1 or 2 hereof or
pursuant to any D & O Insurance purchased and maintained by Corporation;

                  (b) when  Agent's  claim for  indemnification  hereunder is by
reason of the fact that  Agent is or was  serving  or at any time  serves at the
request of  Corporation  as a  director,  officer,  employee or agent of another
entity,  except to the extent Agent is not indemnified by such other entity, and
to  that  extent  only  after  Agent  has  used  his  best   efforts  to  obtain
indemnification from the other entity.

                  (c) in  respect to  remuneration  paid to Agent if it shall be
determined  by  a  final  judgment  or  other  final   adjudication   that  such
remuneration was in violation of law;

                  (d) on  account  of any suit in  which  judgment  is  rendered
against  Agent for an  accounting  of profits  made from the purchase or sale by
Agent of securities of  Corporation  pursuant to the provisions of Section 16(b)
of the  Securities  Exchange  Act of 1934  and  amendments  thereto  or  similar
provision of any federal, State or local law;



<PAGE>


                  (e) on account of Agent's conduct which is finally adjudged to
have been knowingly fraudulent, deliberately dishonest or willful misconduct;

                  (f) if a final decision by a court having  jurisdiction in the
matter shall determine that such indemnification is not lawful.

         4.  Continuation  of  Indemnity.  All  agreements  and  obligations  of
Corporation  contained  herein  shall  continue  during  the  period  Agent is a
director  or  officer of  Corporation  (or is or was  serving at the  request of
Corporation as a director,  officer,  employee or agent of another  corporation,
partnership,  joint  venture,  trust or other  enterprise)  and  shall  continue
thereafter so long as Agent shall be subject to any possible Claim.

         5.  Notification and Defense of Claim.  Promptly after receipt by Agent
of notice of the commencement of any Claim,  Agent shall, if  indemnification or
advance of expenses in respect thereof is to be sought from Corporation pursuant
to this  Agreement,  give prompt and timely  notification  to Corporation of the
commencement thereof; but the omission so to notify Corporation will not relieve
it from any  liability  which it may have to Agent  otherwise  than  under  this
Agreement.  With respect to any such Claim as to which Agent promptly and timely
notifies Corporation of the commencement thereof:

                  (a) Corporation shall  be entitled  to participate  therein at
its own expense; and

                  (b) Except as otherwise  provided below, to the extent that it
may wish,  Corporation  jointly  with any  other  indemnifying  party  similarly
notified  shall  be  entitled  to  assume  the  defense  thereof,  with  counsel
satisfactory to Agent. After notice from Corporation to Agent of its election so
to assume the defense  thereof,  Corporation  shall not be liable to Agent under
this Agreement for any legal or other expenses subsequently incurred by Agent in
connection with the defense thereof other than reasonable costs of investigation
or as otherwise  provided below. Agent shall have the right to employ counsel in
such Claim but the fees and expenses of such counsel  incurred after notice from
Corporation of its assumption of the defense  thereof shall be at the expense of
Agent  unless (i) the  employment  of counsel  by Agent has been  authorized  by
Corporation,  (ii) Agent  shall have  reasonably  concluded  that there may be a
conflict of interest between Corporation and Agent in the conduct of the defense
of such Claim or (iii)  Corporation  shall not in fact have employed  counsel to
assume the defense of such Claim, in each of which cases the reasonable fees and
expenses of Agent's counsel shall be at the expense of Corporation.  Corporation
shall not be entitled to assume the defense of any Claim brought by or on behalf
of Corporation  or as to which Agent shall have reached the conclusion  provided
for in (ii) above.



<PAGE>


                  (c)  Corporation  shall not be liable to indemnify Agent under
this Agreement for any amounts paid in settlement of any Claim effected  without
its written consent.  Corporation shall not settle any Claim in any manner which
would impose any penalty or limitation on Agent without Agent's written consent.
Neither  Corporation nor Agent shall unreasonably  withhold their consent to any
proposed settlement.

         6.  Advancement  of Expenses.  If  Corporation  does not assume Agent's
defense  pursuant to the  provisions  of Section 5(b) hereof,  then  Corporation
shall advance the expenses of Agent in accordance  with the following  terms and
conditions:

         Within 10 days  after  the  receipt  by  Corporation  from  Agent of an
         invoice from his legal  counsel  representing  a retainer or legal fees
         and expenses,  or from another person or entity for expenses,  actually
         incurred or expected  to be  actually  incurred by Agent in  connection
         with the defense or disposition of any Claim,  including any appeals in
         connection  therewith,  Corporation  shall promptly pay to Agent, or to
         such other person as Agent may instruct,  the amount shown to be due on
         such invoice as an advance in advance of the disposition of such Claim.
         Any  such  invoice  submitted  by  Agent  shall  be  accompanied  by  a
         certificate  signed  by Agent  to the  effect  that  (i) he  reasonably
         believes that the retainer or legal fees and expenses for which payment
         is sought are or would be indemnifiable pursuant to applicable laws and
         (ii) he will  immediately  use the funds so advanced by  Corporation to
         pay such invoice.

         7. Obligation to Repay.  Agent shall repay to Corporation  promptly any
amounts paid by  Corporation  to Agent  pursuant to this Agreement to the extent
that it  shall  be  ultimately  determined  that  Agent  is not  entitled  to be
indemnified by Corporation pursuant to applicable law.
