Item 1.  Business

         The  nature of Canada  Southern  Petroleum  Ltd.'s  (the  "Company"  or
"Canada Southern")  business is described at Item 1(c) herein, and a description
of its principal oil and gas properties in Canada appears in Item 2 herein.  For
additional  information regarding the development of the Company's business, see
"Properties" and "Supplemental Information on Oil and Gas Activities".

         (a)  General Development of Business

Yukon Territory - The Kotaneelee Field

         The  Company's  principal  asset  is a  30%  carried  interest  in  the
Kotaneelee  gas field located on Ex-Permit 1007 (31,888 gross acres or 9,566 net
acres) in the extreme southeastern corner of the Yukon Territory. This partially
developed  field is connected to a major  pipeline  system.  Two wells have been
completed  to date that are  capable of an  estimated  output of in excess of 60
million  cubic feet per day, the  capacity of the field  dehydration  plant.  At
December 31, 1998, field production was  approximately  60-65 million cubic feet
("mmcf") per day. The operator is Anderson  Exploration Ltd., which acquired all
of Columbia Gas  Development  of Canada  Ltd.'s  interests.  See Item 3 - "Legal
Proceedings"  for a discussion  of the  Kotaneelee  Litigation  concerning  this
asset.

         Production  at  Kotaneelee  commenced  in February  1991.  According to
government  reports,  total  production  in billion  cubic feet ("bcf") from the
Kotaneelee gas field since 1991 has been as follows:

                       Calendar Year               Production (bcf)
                       -------------               ----------------

                           1993                          17.5

         At  present,  the  Company  does not  receive  any cash  payments  from
production  but is credited with 30% of the gross  revenues until a like percent
of the working interest costs,  exclusive of any interest expense, are recovered
by the  operator.  The Company  will not receive  any  payment  from  production
revenues until its share of the working  interest costs are recovered.  When the
deferred  costs are recovered,  30% of gross  revenues (net of gross  overriding
royalties)  less  30% of  current  working  interest  costs  will be paid to the
Company.  Gross  overriding  royalties  amount  to 10% to the  Canadian  Federal
government  and 4.06% to certain  individuals.  The operator has reported to the
Company  development  costs  totaling  approximately  $95,849,000  and,  of that
amount,  approximately $19,039,000  (Company share = $5,712,000)  remained to be
recovered at December 31, 1998.  The Company has  contested  the amount of costs
that have been charged to the carried interest account. It is estimated that the
Company will not begin to receive  proceeds from the Kotaneelee gas field before
the year 2000,  based  upon a price of $1.28 per mcf  (average  1998  price) and
current production rates. The period before payment to the Company begins may be
shorter or longer,  depending on prevailing market conditions and the results of
the Kotaneelee Litigation.

British Columbia Properties

         The  Company's  major source of income has been from oil and gas fields
in northeast British Columbia. These fields, developed in the 1950's and 1960's,
produce revenue  through both working and carried  interest  agreements.  During
November 1998, the major working interests in these fields were sold to Canadian
Natural Resources Ltd. ("CNRL") for approximately $3.5 million.

         In addition  to the  producing  properties,  since 1988 the Company has
acquired a number of leases in northeast  British  Columbia by  participating in
British  Columbia land sales.  To date five wells have been drilled on the lands
resulting in three oil discoveries and two dry holes. Currently,  the Company is
defining the prospects by geophysics.  Work completed to date indicates that six
of the prospects justify drilling. The Company estimates that the drilling costs
(excluding completion costs) of the six prospects would be $1,625,000.  However,
as most of these wells would be wildcat wells  (exploratory  wells), the Company
plans to reduce its risk by selling or  farming  out part of its  interest.  The
timing of the drilling is dependent on the  availability  of funds.  The Company
anticipates  that its  average  net cost per well  (assuming  a farmout or sale)
would  be  approximately  $75,000,  or a total of  $525,000,  for  drilling  and
completion costs.

         One  prospect  has been farmed out on a seismic  option  basis.  If the
farmee  elects to drill a well,  the Company  will not be required to pay any of
the drilling  costs.  In 1998,  the Company  acquired  leases on two  additional
prospects.

         In the Paradise area, one well that was drilled and completed as an oil
well in 1997 proved to be  non-commercial.  Another oil well,  which was drilled
under a farmout arrangement,  is currently suspended. An additional farmout well
which was drilled in late 1997 has been plugged and abandoned.


<PAGE>

         The Company also has interests at Buick Creek,  Wargen and Siphon.  The
Siphon and Wargen fields have new operators.  As these properties are held under
the  carried  interest  agreements,  the  Company  is not aware of any  proposed
exploration  and  development  plans for these  properties,  but anticipates the
change of operator will cause new work to be done.

Arctic Islands

         As of December 31, 1998,  the Company held working  interests in 45,100
gross  acres  (1,817 net acres) and  carried  interests  in 131,730  gross acres
(37,180 net acres) in the Sverdrup  Basin,  located in the Arctic  Islands.  The
Hecla, Whitefish,  Drake Point, Roche Point,  Kristoffer,  Romulus and Bent Horn
fields have been designated  significant discovery lands ("SDL" ) by the Federal
Government.  The  Company's  interests in the SDL's have been  retained  pending
development.

         Panarctic  Oils Ltd.  ("Panarctic"),  the  operator,  received  Federal
government  regulatory  approvals for a pilot project to move shipments of crude
oil from the Bent Horn field by tanker through the Northwest Passage to southern
Canada in 1985. Through December 31, 1996,  approximately 2.7 million barrels of
Bent Horn crude had been sold with  deliveries  being made at northern  Canadian
and  European  markets as well as the  eastern  seaboard  market.  In 1996,  the
operator  decided  to shut down  production  from the field  and  dismantle  the
production  facilities because of economic  uncertainties.  The Company has a 5%
carried interest in the area which has not yet reached payout status. The timing
of any payout is uncertain.

Northwest Territories Properties

         The Company has a 45% carried interest in the Northwest  Territories in
the Celibeta  field  designated as  Significant  Discovery  Lands ("SDL") by the
Federal  Government  (1,594  gross  acres and 717 net  acres).  The gas field is
presently shut-in.

Alberta

         In 1994,  the Company  purchased a 5% working  interest in the Kitscoty
heavy oil field and the  related  facilities.  Oil  recovery  from this field is
being enhanced by steam injection.

         In 1996, the Company purchased an additional 5% working interest in the
Kitscoty field.  Three more wells were drilled in 1996; two horizontal wells and
one  vertical  well.  All the wells  encountered  oil and were  completed as oil
wells.  One well  also  discovered  three  potential  gas  zones  which  will be
evaluated for future use as fuel for the steam generation  needed to enhance the
oil production.  Scheduled remedial work programs have been postponed pending an
increase in the current low  netbacks on heavy oil.  Additional  work at the new
Lloydminister  heavy oil discovery at 16-2-51-2 W4M has also been  postponed for
this reason.


<PAGE>


         During 1997 and 1998, the Company  participated  in the exploration and
development  of a  glauconite  heavy oil project in the  Atlee/Majestic  area. A
multitude of production problems occurred which caused numerous delays. Although
the project was successful in developing  substantial  reserves,  the prevailing
low heavy oil prices made the economic  return on this  project  less  favorable
than other Company projects. For this reason, the Company's interest was sold in
November 1998 for $2.2 million.

         The  Company  also  acquired a 10-20%  working  interest in over 12,000
acres in four other areas of Alberta. These lands were purchased on the basis of
seismic  work  which  showed  a number  of  promising  prospects.  Subsequently,
additional seismic work has confirmed the potential of those prospects.  One was
drilled in 1997 and completed as a potential gas well. A second well was drilled
in early 1998 and completed as an oil well.

         In 1998,  the  Company  purchased  leases  (100%  interest)  in an area
prospective  for both oil and gas. The leases are currently being evaluated with
the intent of drilling in late 1999 or early 2000.

         In Alberta,  the Company  currently has working  interests ranging from
10% to 100% in a total of 1,920 gross (326 net) developed acres and 26,869 gross
(8,448 net) undeveloped acres.

Saskatchewan

         The  Company  has  a  3.75%  working   interest  in  five  sections  in
Saskatchewan.  During 1997, three wells were drilled on the lands resulting in 2
dry holes and 1 shut-in gas well.

United States

         Texas

         In 1996 and 1997,  the  Company  participated  in the  drilling of four
wells in Texas  which  resulted  in four  potential  oil  wells.  Because of low
production  rates  and low oil  prices,  three  of the  wells  have  since  been
abandoned, leaving one producing oil well. During 1998, the costs of these wells
totaling  $489,000  were written off.  Based on the  technical  results of these
wells in which it has a relatively small interest,  the Company  commenced a new
leasing program and acquired four leases (100% interest) on which it conducted a
seismic  program in 1998.  Currently,  plans are being made to test the first of
several Chappel reef prospects on these leases in the second quarter of 1999.


<PAGE>


         California

         During March 1998,  the Company  agreed to  participate  with two other
companies in a heavy oil recovery project in California.  The field is estimated
to have  approximately  12 million  barrels of oil in place with only 13% of the
oil recovered to date.  The initial  purchase price for a 90% (75% after payout)
interest in the project is U.S.  $200,000  (Company  share 30% - U.S.  $60,000).
Capital  expenditures were expected to be U.S. $600,000 to perform remedial work
on the field and to complete a pilot stream flood program  during the first year
of  the  project  (Company  share  U.S.  $180,000).   If  the  total  amount  of
expenditures is  less than  U.S. $600,000,  the participants'  interests will be
reduced proportionately to an amount which is not less than 10% (Company share -
3%).  Because of the current low price of heavy oil, major  development  work on
the project has been suspended  pending an increase in oil prices.  In addition,
the Company also wrote off the  carrying  costs of the property in the amount of
$196,000 during 1998.

         (b)      Financial Information about Industry Segments

         Since the Company is primarily  engaged in only one  industry,  oil and
gas exploration and development, this item is not applicable to the Company. See
Item 8 - "Financial  Statements  and  Supplemental  Data" for general  financial
information concerning the Company.

         (c)      (1)      Narrative Description of the Business

                  The  Company  was   incorporated  in  1954  under  the  Canada
Corporations   Act.  In  1979,  it  became  subject  to  the  Canadian  Business
Corporations Act and in 1980, was continued under the Nova Scotia Companies Act.

         The Company is,  either in its own right,  or through  other  entities,
engaged in the  exploration  for and  development  of  properties  containing or
believed to contain recoverable oil and gas reserves and the sale of oil and gas
from these properties.  Although many of the properties in which the Company has
interests are undeveloped,  all properties with proved reserves are partially or
fully  developed.  The  Company's  interests  in  exploratory  ventures  are  on
properties located in Alberta, British Columbia, Saskatchewan, the Northwest and
Yukon Territories and the Arctic Islands in Canada and in the United States. The
Company's principal asset is its 30% carried interest in the Kotaneelee field, a
partially  developed gas field (See Item 3 - "Legal  Proceedings".)  The Company
also has interests in producing properties in British Columbia and Alberta.

Most of this acreage is covered by carried  interest  agreements,  which provide
that revenues are not payable to the Company until  expenditures by the carrying
partners have been recouped from  production,  and that operating  decisions are
made by the carrying  partners.  Generally,  the Company may, at any time, as to
each block or economic unit, elect to convert from a carried  interest  position
to  a  working  interest   position  by  paying  its  share  of  the  unrecouped
expenditures  for the unit (i.e.,  expenditures  not  recouped  from  production
revenues).  At December 31, 1998, the Company's share of unrecouped expenditures
were as follows:

         British Columbia:
           Ex-permit 149                   $ 4,013,000

         Yukon and Northwest Territories:
           Ex-permit 1007 (Kotaneelee)*    $19,039,000
           Ex-permit 2713 (Celibeta)       $   321,000

                                    Concessions Held

                                    Permits and concessions are important to the
Company's  operations,  since they allow the  search for and  extraction  of any
crude oil and natural gas  discovered  on the areas  covered.  See the  detailed
schedule of properties under Item 2 - "Properties."

                           (v)      Seasonality of Business

                                    The  Company's  business  is  not  seasonal,
except  that  sales of  natural  gas peak  during  the  winter  heating  season.
Exploration  and  development  activities  are  restricted in certain areas on a
seasonal basis because extreme weather conditions affect  transportation and the
ability to pursue these activities.

                                    Not applicable.

                           (vii)    Customers

                                    Substantially  all  oil production  from the
Company's properties for the current year was purchased by CNRL, the operator of
the majority of the producing properties.  Most of the natural gas produced from
Company  properties  was sold by the  operator,  Petro  Canada,  to various  gas
marketers.  The  production  from the Kotaneelee gas field is also being sold by
the working interest partners who have not disclosed the purchasers.

                                    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,  both internally within the oil and
gas industry and externally with producers of other types of energy. The ability
to exploit a discovery of oil or gas is dependent  upon  considerations  such as
the ability to finance  development  costs, the  availability of equipment,  and
the ability  to overcome  engineering and construction  delays and difficulties.
The  Company  must  compete  with  companies  which have  substantially  greater
resources  available to them.  Because the majority of Company  interests are in
remote areas,  operation of its  properties is more difficult and costly than in
more accessible areas.

                                    Furthermore,  competitive  conditions may be
substantially  affected by various  forms of energy  legislation  which may have
been or may be proposed  in the United  States and  Canada;  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.  For a further
discussion of Canadian  governmental  regulation of the petroleum industry,  see
Item 1(d)(2) - "Risks Attendant to Foreign Operations".

                           (xii)    Environmental Regulation

                                    In the  exploration  for and  development of
natural   resources,   the  Company  is  required  to  comply  with  significant
environmental laws and regulations which add to the expense of those activities.
The Company has not been required to spend significant sums to comply with clean
up laws and regulations.  Compliance by the Company with governmental provisions
regulating the discharge of materials to the  environment or otherwise  relating
to the protection of the  environment are not expected to have a material effect
on the capital expenditures, earnings or competitive position of the Company.

                           (xiii)   Number of Persons Employed by Company


                                    The Company  currently  has  three full time
employees, all of whom are located in Canada. The Company also relies to a great
extent on consultants  (approximately 10) for technical,  legal,  accounting and
administrative  services.  The Company uses consultants  because it is more cost
effective than employing a larger full time staff.

         (d)      Financial Information about Foreign and Domestic Operations
                  and Export Sales

                  (1)      Revenues, Operating Losses and Identifiable Assets

                           Substantially  all of the Company's  operating assets
and revenues are attributable to its operations in Canada.  Operating losses are
substantially attributable to the ongoing Kotaneelee litigation.

                  (2)      Risks Attendant to Foreign Operations

                           The properties in which the Company has interests are
located  primarily  in Canada 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;  native rights;  changes in foreign  exchange  controls;
currency  revaluation;  burdensome  royalty  terms;  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 conversion, proration, curtailment, cessation or other forms
of limiting or  controlling  production of, or  exploration  for,  hydrocarbons.
Thus, an  investment in the Company  represents an exposure to risks in addition
to those inherent in petroleum exploratory ventures.

Governmental Regulation of the Canadian Oil and Natural Gas Industry

         The oil and  natural  gas  industry  in Canada is subject to  extensive
controls and  regulations  imposed by various  levels of government  relating to
land  tenure,   production,   production  facilities,   pricing  and  marketing,
royalties,  environmental protection and other matters.  Outlined below are some
of the more significant  aspects of the legislation,  regulations and agreements
governing the oil and natural gas industry in Canada. All current legislation is
a matter of public  record  and the  Company is unable to  predict  whether  any
additional legislation or amendments may be enacted.

Land Tenure

         Crude oil and natural gas  located in the  western  provinces  is owned
predominantly by the respective provincial  governments.  Provincial governments
grant  rights to explore for and produce oil and natural gas pursuant to leases,
licenses  and  permits  for  varying  terms  from two  years  and on  terms  and
conditions set forth in provincial legislation including requirements to perform
specific work or make  payments.  Oil and natural gas located in such  provinces
can also be  privately  owned and rights to explore for and produce such oil and
natural  gas are  granted  by  lease  on such  terms  and  conditions  as may be
negotiated.  The term of both Crown and freehold leases will generally  continue
as long as oil or natural gas is produced from the property.

         Oil and natural gas rights on federal lands outside of the provinces is
generally  regulated  by the  Government  of Canada  unless  authority  has been
delegated by agreement to the  territorial  government or the  government of the
province  adjacent to the federal  offshore  area. In May 1993, the Canada Yukon
Oil and Gas Accord was signed  which  allowed  for the  transfer to the Yukon of
authority to administer  and control oil and natural gas  resources  within that
territory and for the  establishment  of an Oil and Gas Management  Regime.  The
transfer  has been  completed  and the lands are now  administered  by the Yukon
Government.

Production and Production Facilities

         The Governments of Canada,  Alberta,  British Columbia and Saskatchewan
have enacted statutory  provisions  regulating the production of oil and natural
gas. These regulations may restrict the maximum allowable production from a well
based on reservoir engineering and/or conservation  practices.  The construction
and  operation of facilities to recover and process oil and natural gas are also
subject to regulation.

Pricing and Marketing - Oil

         In Canada, producers of oil negotiate sales contracts directly with oil
purchasers, with the result that the market determines the price of oil. Certain
purchasers  periodically  advertise  for  volumes  of oil they are  prepared  to
purchase and the price being offered for such volumes. The price depends in part
on oil quality,  prices of competing fuels,  distance to market and the value of
refined products.


<PAGE>


Pricing and Marketing - Natural Gas

         In  Canada,  the price of  natural  gas is  determined  by  negotiation
between buyers and sellers, with the result that the market determines the price
of natural gas. Natural gas exported from Canada is subject to regulation by the
National  Energy Board ("NEB") and the Government of Canada.  Exporters are free
to negotiate  prices and other terms with  purchasers,  provided that the export
contracts must continue to meet certain  criteria  prescribed by the NEB and the
Government of Canada. As is the case with oil, natural gas exports for a term of
less than two years must be made  pursuant  to an NEB order,  or, in the case of
exports  for a longer  duration,  pursuant  to an NEB  license  and  Governor in
Council approval.

         The  Governments of Alberta,  British  Columbia and  Saskatchewan  also
regulate the volume of natural gas which may be removed from those provinces for
consumption   elsewhere   based  on  such   factors  as  reserve   availability,
transportation arrangements and market considerations.

Royalties and Incentives

         The royalty regime is a significant  factor in the profitability of oil
and natural gas  production.  Royalties  payable on production  from lands other
than Crown lands are  determined by  negotiations  between the mineral owner and
the  lessee,  although  production  from  such  lands  may  also be  subject  to
provincial taxes and  regulations.  Crown royalties are determined by government
regulation  and are  generally  calculated  as a percentage  of the value of the
gross production, and the rate of royalties payable generally depends in part on
prescribed  reference prices, well productivity,  geographical  location,  field
discovery date and the type or quality of the product produced. The value of the
gross  production  for royalty  purposes  may be based on a deemed value for the
product rather than the actual value received by the interest holder.

         From time to time the Governments of Canada, Alberta,  British Columbia
and Saskatchewan have established incentive programs which have included royalty
rate reductions, royalty holidays and tax credits for the purpose of encouraging
natural gas and oil exploration or enhanced  recovery  projects.  Incentives are
intended to enhance the  existing  cash flow of the oil and natural gas industry
and to improve the economics of finding and  developing  new and more costly oil
and natural gas reserves.  Oil royalty  holidays for specific  wells and royalty
reductions  reduce the amount of Crown  royalties paid by the interest holder to
the  respective  government.  Tax  credit  programs  provide  a rebate  on Crown
royalties paid.

Environmental Regulation

         The oil and natural gas industry is subject to environmental regulation
pursuant to local, provincial and federal legislation. Environmental legislation
provides for restrictions  and prohibitions on spills,  releases or emissions of
various  substances  produced in  association  with  certain oil and natural gas
industry  operations.  An  environmental  assessment  and review may be required
prior  to  initiating   exploration  or  development   projects  or  undertaking
significant changes to existing projects. In addition, legislation requires that
well and facility  sites be abandoned and reclaimed to the  satisfaction  of the
appropriate  authorities.  A  breach  of  such  legislation  may  result  in the
imposition of fines or penalties.  Federal environmental  regulations also apply
to the use and transport of certain  restricted and prohibited  substances.  The
Company is committed to meeting its  responsibilities to protect the environment
wherever  it  operates  and  believes  that it is in  material  compliance  with
applicable environmental laws and regulations. The Company has not been required
to  spend  significant  sums to  comply  with  clean  up laws  and  regulations.
Compliance by the Company with governmental  provisions regulating the discharge
of materials to the  environment or otherwise  relating to the protection of the
environment  are  not  expected  to  have  a  material  effect  on  the  capital
expenditures, earnings or competitive position of the Company.

properties in British Columbia and Alberta and in several exploration prospects.
The exploratory  ventures are properties  located in British Columbia,  Alberta,
Saskatchewan,  the Yukon and  Northwest  Territories  and the Arctic  Islands in
Canada and in the United  States.  Geophysical,  geological and drilling work on
the Company's  properties is conducted by the operators under various agreements
with the Company. The results of this work are reviewed by Company personnel and
consultants retained by the Company.

         (b)  (1)  The  information  regarding  reserves,  costs  of oil and gas
activities,  capitalized costs,  discounted future net cash flows and results of
operations  is  contained in Item 8 - "Financial  Statements  and  Supplementary
Data."

Item 3.  Legal Proceedings

         The  Company,  which has a 30%  interest in the  Kotaneelee  gas field,
believes  that the  working  interest  owners in the field  have not  adequately
pursued the  attainment of contracts for the sale of Kotaneelee  gas. In October
1989 and in March 1990,  the Company  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  Company  claims  that the  Defendants  breached  either a contract
obligation  and/or a  fiduciary  duty owed to the Company to market gas from the
Kotaneelee  gas field when it was  possible to so do. The Company  asserts  that
marketing  the  Kotaneelee  gas was  possible  in 1984 and  that the  Defendants
deliberately failed to do so. The Company seeks money damages and the forfeiture
of the Kotaneelee gas field.  The Company  presented  evidence at trial that the
money damages sustained by the Company were approximately $100 million.

         In  addition,  the  Company  has  claimed  that the  Company's  carried
interest  account should be reduced  because of improper  charges to the carried
interest account by the Defendants.  The Company claims 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 Company claims that  expenditures  made to repair and rebuild the
field's dehydration plant should not have been necessary had the facilities been
properly  constructed and maintained by the Defendants.  The  expenditures,  the
Company claims,  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.


<PAGE>


         The Company claims that production from the field should have commenced
in 1984. At that time the field's carried interest account was approximately $63
million.  The Company  claims  that by 1993 at least $34 million of  unnecessary
expenses  had been  wrongfully  charged to the  carried  interest  account.  The
Company's 30% share of these expenses would be approximately $10.2 million.  The
Company  further  claims 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. At present,
the Company does not expect to receive revenues before the year 2000, based on a
price of Cdn. $1.28 per mcf and current production rates.

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

         The parties to the litigation have conducted  extensive discovery since
the filing of the claims.  The trial began on  September 3, 1996 and the Company
completed the  presentation  of its case against the Defendants on September 16,
1998. Based upon newly discovered evidence, the Company filed a new claim during
May 1998 that the Defendants failed to develop the field in a timely manner. The
Company is unable to estimate the time necessary to conclude the litigation.

Matters Ancillary to Kotaneelee Litigation

         In its 1989  statement  of  claim,  the  Company  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 Company  will be assessed a  processing
                  fee on gas throughput.

         With respect to the first issue, the Company maintains that no interest
should  accrue  on the  account  and the  Defendants  have  not  contested  this
position.  With  regard to the second  issue,  the  Company  maintains  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.



<PAGE>


         On January 22, 1996, the Company settled two claims outstanding against
the Company in the Court of Queens Bench, Calgary,  Alberta,  which related to a
suit brought against  AlliedSignal  Inc.  ("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  Company  for any costs in  connection  with the  Kotaneelee
Litigation.  The Company 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.

         In 1991,  Anderson  Exploration  Ltd.  acquired  all of the  shares  in
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 Canadian
lawsuit.  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.

         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,  the Company
estimated  that  taxable  costs,   assuming  a  twelve  month  trial,  could  be
approximately  $1.5  million  and noted  that the judge in complex  and  lengthy
trials has the discretion to increase an award.

         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 matters before the Court. In addition,  the Company believes
that the trial  will  extend  well  beyond  its  original  time  estimates  and,
therefore, potentially 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 it
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.  A cost award
against the Company  could be of sufficient  magnitude to  necessitate a sale of
Company assets or a debt or equity financing to fund such an award. There are no
assurances that any such sale or financing would be consummated.


<PAGE>

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

         (c)      Dividends

         The Company has never paid a dividend on its Limited Voting Shares. Any
future  dividends  will  be  dependent  on  the  Company's  earnings,  financial
condition, and business prospects. The Company is legally restricted from paying
any  dividend  or making  any other  payment to  shareholders  (except by way of
return of capital) on the Limited  Voting Shares until its  accumulated  deficit
($23,849,000 at December 31, 1998) is eliminated.

         Current  Canadian law does not restrict the  remittance of dividends to
persons not resident of Canada.  Under  current  Canadian tax law and the United
States-Canada tax treaty, any dividends paid to U.S.  shareholders are currently
subject to a 15% Canadian withholding tax.

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

         Statements   included  in  Management's   Discussion  and  Analysis  of
Financial Condition and Results of Operations which are not historical in nature
are intended to be, and are hereby  identified as, "forward looking  statements"
for  purposes  of the  "Safe  Harbor"  Statement  under the  Private  Securities
Litigation Reform Act of 1995. The Company cautions readers that forward looking
statements  are  subject to certain  risks and  uncertainties  that could  cause
actual results to differ  materially from those indicated in the forward looking
statements.

(1)      Liquidity and Capital Resources

         At December 31, 1998, the Company had  approximately $7 million of cash
and securities  available which amount  includes the $5.7 million  proceeds from
the sale of certain  properties that was completed in November 1998. These funds
are expected to be used for general corporate  purposes,  including  exploration
and development  and to continue the Kotaneelee  field  litigation.  The Company
estimates  that it  currently  has adequate  working  capital for 1999 and 2000.
However,  it might be required  to raise  additional  funds  through the sale of
properties or other means in order to complete the Kotaneelee Litigation.

         Cash  flow used in  operations  during  1998  increased  to  $2,351,000
compared to $1,003,000 during the 1997 period. The $1,348,000 difference between
the periods was caused primarily by the following:


                  Increase in loss from operations            $(1,332,000)
                  Increase in accounts receivable and other     1,488,000
                  Net change in current liabilities            (1,504,000)
                                                              ------------

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

         A  significant  proportion  of the  Company's  property  interests  are
covered by carried interest agreements,  which provide that expenditures made by
the operator are recouped solely out of revenues from production.  Major capital
expenditures  made by the operators  have an impact on the  Company's  cash flow
from  operations as no revenues are reported or received until the capital costs
have been  recovered by the  operator.  Certain  properties  in the Fort Nelson,
British  Columbia area in which the Company has carried  interests  have reached
payout status. Proceeds from these carried interests plus oil and gas sales from
working interest  properties are the Company's major sources of working capital.
During 1998, the Company sold the majority of its Canadian  working interest oil
and gas properties, therefore, the Company expects a significant decrease in its
1999 revenues, royalties and lease operating expenses.


<PAGE>


         The Company is currently evaluating and expects to continue to evaluate
oil and gas properties and may make  investments  in such  properties  utilizing
cash on hand. The Company  anticipates  that its capital  expenditures  for land
acquisitions and drilling for the year 1999 will be approximately $1,200,000. In
addition,  substantial  continuing  expenses  are  expected  to be  incurred  in
connection  with the Kotaneelee  Litigation.  During 1998, the Company  expended
approximately  $2.4 million in connection with the Kotaneelee  Litigation  which
has been the principal cause of the Company's losses since 1991.

         The Company has established a reserve for its potential share of future
site  restoration  costs.  The  estimated  amount of these  costs,  which  total
$271,000,  is being  provided on a unit of production  basis in accordance  with
existing legislation and industry practice.

         At  December  31,  1998,  the  Company  believes  that it is year  2000
compliant. In addition, the year 2000 change will have no material impact on the
Company's internal operations or financial results. However, the Company will be
dependent on its  suppliers,  partners and  customers to make their systems year
2000 compliant.

1998 vs. 1997

         The net  loss  for the  year  1998 was  $2,706,537,  ($.19  per  share)
compared to a net loss of  $1,757,664  ($.12 per share) for the 1997  period.  A
summary of revenue and expenses during the periods is as follows:

         Oil sales  decreased  by 20% due  primarily  to a 34%  decrease  in the
average  prices of oil sold  which was  partially  offset  by a 2%  increase  in
production.  There was also a decrease in  royalties  paid by the  Company.  The
Company  sold the  majority  of its oil  producing  properties  in two  separate
transactions  effective  July 1, 1998 and September 1, 1998.  The 1998 royalties
paid amount includes a provincial  royalty tax credit in the amount of $117,000.
Oil unit sales in barrels ("bbls") (before deducting  royalties) and the average
price per barrel sold during the periods indicated were as follows:

         Gas sales  increased  35% because of a 52%  increase in number of units
sold which was  partially  offset by a 6% decrease in the average price for gas.
In addition,  gas sales include  royalty income which decreased 13% in 1998. The
Company sold the majority of its working interest gas properties  effective July
1, 1998. The primary increase in gas production was the payout of two wells that
had been in a penalty  position.  These wells were  included  in the  properties
sold.  The volumes in million  cubic feet  ("mmcf") and the average price of gas
per  thousand  cubic feet  ("mcf")  sold  during the periods  indicated  were as
follows:

         Proceeds under carried  interest  agreements  decreased 57% to $207,000
during 1998 compared to $476,000 in 1997.  During 1998,  there were  significant
expenditures  made  by  the  operators  of  the  carried  interest   properties,
therefore, revenues from these properties will be substantially lower in 1999.

         Interest  and  other  income  decreased  44% in 1998.  Interest  income
decreased  from  $336,000  to  $194,000  in 1998  due to the  decrease  in funds
available for investment and lower interest rates. In addition,  the 1998 period
includes  proceeds  from the  sale of  seismic  data in the  amount  of  $27,000
compared to $59,000 from such sales in 1997.  Interest income should increase in
1999 with the increased funds available from the 1998 sale of properties.  It is
not possible for the Company to estimate the amount of future seismic data sales
which are  dependent on a purchaser's  evaluation  of a prospective  oil and gas
prospect for the related seismic data that the Company owns.

         Gain on the sale of properties in 1998 amounted to $1,378,000 primarily
represents  the sale of the  Company's  heavy oil  properties in Alberta and the
sale of certain working interest properties in British Columbia.

         General and  administrative  costs  increased 18% in 1998 to $1,301,000
from $1,105,000 in 1997 primarily as a result of increased  Company  activity in
connection with the Kotaneelee litigation and the Company's exploration program.
In addition,  the  expenses  increased  in the United  States  because of the 7%
increase in the value of the U.S.  dollar compared to the Canadian dollar during
1998.



<PAGE>


         Legal  expenses  increased  24% during 1998 to  $2,358,000  compared to
$1,898,000  during 1997. These expenses are related primarily to the cost of the
Kotaneelee litigation.  During 1998, the Company continued the presentation of a
major part of its case against the working interest partners. The Company's case
was completed on September 16, 1998 and Defendants' case is now proceeding.  The
1998 costs represent both legal fees and the cost of various Company experts who
testified,   were  being   prepared   for   testimony,   or   assisted   in  the
cross-examination of defense witnesses.

         Lease  operating  costs increased 22% from $799,000 in 1997 to $976,000
in the 1998 period. The increase  represents the charges by the operators of the
Company's properties which is related to the increased production.  In addition,
the  Company's  share  of  production  costs  in  producing  Alberta  heavy  oil
increased.  Lease  operating  costs should  decrease in 1999 because of the 1998
sale of properties.

         Depletion,  depreciation and amortization expense increased 39% in 1998
to $870,000  from  $624,000 in 1997.  The  increase in  depletion in 1998 is the
result  of  increased  production  and the  amount  of  additional  costs  being
depleted.

         A foreign  exchange  gain of $179,000 was recorded in 1998,  contrasted
with a gain of $231,000 on the Company's U.S.  investments in 1997. In 1998, the
gain was  attributable  to the continuing  strengthening  of the U.S.  dollar as
compared to the Canadian dollar on the Company's U.S. investments.

         Abandonments  and write downs were $685,000 which resulted from a write
down of certain of the Company's  properties in California and Texas. There were
no abandonments and write downs in 1997.

         Income taxes. No provision for income taxes was required in 1998. There
has been no income tax  recovery  recorded  in the  accounts  for the  Company's
losses  because there is a lack of virtual  certainty  that the recovery will be
realized.  If at such time as the Company  begins to receive  revenues  from the
Kotaneelee  gas field,  it is expected  that the tax  recovery  benefit of these
losses will be recognized.

1997 vs. 1996

         The net  loss  for the  year  1997 was  $1,757,664,  ($.12  per  share)
compared to a net loss of  $1,461,283  ($.11 per share) for the 1996  period.  A

         Proceeds under carried  interest  agreements  decreased 20% to $476,000
during 1997 compared to $591,000 in 1996. The operator of the Company's  carried
interest  properties  increased  its  development  activities  during late 1996,
thereby incurring additional capital costs which were deducted in 1997. Proceeds
under carried interest agreements are derived from net production revenues after
payout of capital costs.

         Interest  and  other  income  decreased  17% in 1997.  Interest  income
increased  from  $259,000  to  $336,000  in 1997  due to the  increase  in funds
available for investment from the June 1996 rights offering to shareholders.  In
addition, the 1997 period includes proceeds from the sale of seismic data in the
amount of $59,000 compared to $215,000 from such sales in 1996.



<PAGE>


         General and  administrative  costs  increased 23% in 1997 to $1,105,000
from  $895,000 in 1996.  Capital  taxes,  which are based on the  Company's  net
worth,  increased  $48,000 in 1997.  Directors'  fees increased  $44,000 in 1997
because four nonemployee  directors are being paid fees in 1997 compared to 1996
when only two directors  were paid fees.  Geological  and  engineering  expenses
increased $23,000 in 1997 because of the Company's active  exploration  program.
Shareholders'  expenses  increased  $32,000 in 1997  compared to 1996 because of
increased  printing and mailing costs.  Salaries  increased $39,000 in 1997 with
the addition of a new employee.

         Legal  expenses  increased  18% during 1997 to  $1,898,000  compared to
$1,610,000  during 1996. These expenses are related primarily to the cost of the
Kotaneelee  litigation.  During 1997, the Company  presented a major part of its
case against the working interest partners.  The 1997 costs represent both legal
fees and the  cost of  various  Company  experts  who  testified  or were  being
prepared for testimony.

         Lease  operating  costs increased 68% from $477,000 in 1996 to $799,000
in the 1997 period.  The increased costs are relative to the 85% increase in oil
production.  Although the revenue on these  properties also increased during the
period,  the costs are not yet  proportional  to revenue because some of the new
wells are awaiting installation of production facilities.

         A foreign  exchange  gain of $231,000 was recorded in 1997,  contrasted
with a gain of $25,000 on the Company's  U.S.  investments in 1996. In 1997, the
gain was  attributable to a strengthening  of the U.S. dollar as compared to the
Canadian dollar on the Company's U.S. investments.

         Income taxes. No provision for income taxes is required for the current
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 December 31, 1998,  the carrying value of such  investments  was
approximately  $6,703,000 which was  approximately  equal to fair value and face
value of the  investments.  Since the Company expects to hold the investments to
maturity,  the maturity  value should be realized.  In addition,  the  Company's
investments in marketable  securities  included  investments  held in the United
States which are subject to foreign exchange fluctuations. At December 31, 1998,
the investments in the United States totaled $1,823,000.

                         CANADA SOUTHERN PETROLEUM LTD.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                         (Expressed in Canadian dollars)
                        December 31, 1998, 1997 and 1996

1.       Summary of significant accounting policies

Accounting principles

         The  Company  prepares  its  accounts  in  accordance  with  accounting
principles  generally  accepted in Canada which,  except as described in Note 6,
conform  in  all  material  respects  with  United  States  generally   accepted
accounting principles ("U.S. GAAP").

Consolidation

         The  consolidated  financial  statements include the accounts of Canada
Southern Petroleum Ltd. and its wholly-owned subsidiaries,  Canpet Inc. and C.S.
Petroleum Limited.

Use of Estimates

         The  preparation of 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.   Specifically   estimates  were  utilized  in  calculating
depletion,   depreciation  and   amortization,   site  restoration   costs,  and
abandonments and write downs. Actual results could differ from those estimates.

Cash and cash equivalents

         For the purposes of the statement of cash flows, the Company  considers
all highly liquid investments with a maturity of three months or less to be cash
equivalents.

Oil and gas properties and equipment

         The  Company,   which  is  engaged  primarily  in  one  industry,   the
exploration for and the  development of oil and gas  properties,  principally in
Canada,  follows the full cost method of accounting for oil and gas  properties,
whereby all costs associated with the exploration for and the development of oil
and gas reserves are capitalized. Such costs include land acquisition, drilling,
geological, geophysical and overhead expenses.

         The Company  periodically reviews the costs associated with undeveloped
properties  and  mineral  rights  to  determine  whether  they are  likely to be
recovered.  When such  costs  are not  likely to be  recovered,  such  costs are
transferred to the depletable pool of oil and gas costs.

                         CANADA SOUTHERN PETROLEUM LTD.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                         (Expressed in Canadian dollars)
                        December 31, 1998, 1997 and 1996

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

         The net  carrying  cost of the  Company's  oil  and gas  properties  in
producing  cost  centers is limited to an  estimated  recoverable  amount.  This
amount is the  aggregate  of future net  revenues  from proved  reserves and the
costs of  undeveloped  properties,  net of  impairment  allowances,  less future
general and administrative  costs,  financing costs and income taxes. Future net
revenues  are  calculated  using  year  end  prices  that are not  escalated  or
discounted. For Canadian GAAP future net revenues are undiscounted, whereas, for
U.S. GAAP future net revenues are discounted at 10%.

         The costs of the Company's 30% carried  interest in the  Kotaneelee gas
field are  included  in oil and gas  properties  and in the cost  center for the
purpose of computing  depletion.  In addition,  the Company's share of estimated
net reserves  after payout are also  included in the proved oil and gas reserves
base for the purpose of computing depletion. However, no revenue production data
will be reported for financial  statement purposes until the Company is entitled
to participate in the field's revenue after payout status is achieved.

         Gains or losses  are not  recognized  upon  disposition  of oil and gas
properties unless crediting the proceeds against  accumulated costs would result
in a change in the rate of depletion of 20% or more.

         Depletion is provided on costs  accumulated  in producing  cost centers
including production equipment using the unit of production method. For purposes
of the depletion calculation, gross proved oil and gas reserves as determined by
outside  consultants  are  converted to a common unit of measure on the basis of
their approximate relative energy content.

         Depreciation  has been computed for  equipment,  other than  production
equipment,  on the straight-line  method based on estimated useful lives of four
to ten years.

         Substantially   all  of  the  Company's   exploration  and  development
activities  related  to oil  and gas  are  conducted  jointly  with  others  and
accordingly the  consolidated  financial  statements  reflect only the Company's
proportionate interest in such activities.

Revenue recognition

         The Company recognizes revenue on its working interest  properties from
the production of oil and gas in the period the oil and gas are sold.



<PAGE>


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

         Revenue  under  carried  interest  agreements is recorded in the period
when the proceeds become  receivable.  The Company is entitled to participate in
oil and gas net  revenues  after the  repayment  of  exploration,  drilling  and
completion  expenses to the party or parties  bearing  these costs.  The carried
interest  accounts  are subject to  independent  audits  which are  performed in
subsequent  years. In the past,  these audits have resulted in both positive and
negative  adjustments.  For these reasons,  the proceeds under carried  interest
agreements may fluctuate each year  depending on both capital  expenditures  and
any audit adjustments.

Earnings per share

         Earnings per common share is based upon the weighted  average number of
common and common equivalent shares  outstanding  during the period. In February
1997, the FASB issued Statement No. 128,  Earnings per Share ("EPS"),  which the
Company adopted retroactively  in 1997 for purposes of U.S. GAAP reporting.  The
Company's basic and diluted  calculations of EPS are the same  for both U.S. and
Canadian GAAP.

Future site restoration costs

         Total future site  restoration  costs are  estimated to be $271,000 and
are being  provided on a unit of  production  basis.  The  provision is based on
current costs of complying with existing  legislation and industry  practice for
site restoration and abandonment. At December 31, 1998, approximately $36,000 in
such costs have yet to be accrued. The sale of the Company's Alberta and British
Columbia  properties  during 1998  relieved the Company of $533,000 of potential
future restoration costs.

Income taxes

         The Company  follows the deferral  method of tax allocation  accounting
whereby  the income tax  provision  is based on pre-tax  income  reported in the
accounts.  Under this method,  full provision is made for deferred  income taxes
resulting  from  claiming  deductions  at the  rates  permitted  by  income  tax
legislation, which may differ from those used in the accounts.

Foreign currency translation

         Transactions  for  settlement in U.S.  dollars have been  translated at
average monthly exchange rates. Assets and liabilities in U.S. dollars have been
translated at the year end exchange  rates.  Exchange gains or losses  resulting
from these adjustments are included in costs and expenses.

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

Financial instruments

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

Comprehensive income

         In 1997, the Financial Accounting Standards Board issued FASB Statement
No. 130,  Reporting  Comprehensive  Income. As the Company has no items of other
comprehensive  income, the net loss under U.S. GAAP for all periods presented is
equal to the comprehensive loss.

2.       Cash and cash equivalents

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

5.       Limited Voting Shares and stock options

         The Memorandum of Association  (Articles of Continuance) of the Company
provides that no person (as defined) shall vote more than 1,000 shares.

         Under the  terms of the  Company's  1985,  1992 and 1998  stock  option
plans,  the Company is  authorized  to grant  certain  employees,  directors and
consultants  options to purchase  Limited  Voting  Shares at prices based on the
market price of the shares as determined  on the date of the grant.  The options
are normally exercisable  immediately and issued for a period of five years from
the date of grant.

         On January 27, 1998, the Company's Board of Directors  approved a stock
option  plan  that  permits  the  granting  of  both  stock  options  and  stock
appreciation  rights.  The plan for 700,000 shares was approved by the Company's
shareholders at the June 1998 Annual Meeting.  A total of 700,000 Limited Voting
Shares were reserved for the plan.

         In 1996,  the Company sold 1.3 million  shares to its  shareholders  at
$7.50 per share.  The  proceeds to the  Company  from the rights  offering  were
$9,019,609 after deducting the $494,509 cost of the offering.

Options reserved for future grants              869,634

         On July 8, 1996,  137,000 options to purchase  limited voting shares of
the Company which were previously  granted were canceled and reissued to reflect
the June 1996 rights offering.

         For U.S. GAAP, 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.

          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.

5.       Limited Voting Shares and stock options (Cont'd)

          Option  valuation  models  require  that  input of  highly  subjective
assumptions including the expected stock price volatility. All of the valuations
assumed no expected  dividend.  The assumptions used in the 1996 valuation model
were:  risk free  interest  rate - 6.7%,  expected  life - 5 years and  expected
volatility - .396. The  assumptions  used in the 1997 valuation model were: risk
free  interest rate - 5.7%,  expected  life - 5 years and expected  volatility -
 .459. The assumptions  used in the 1998 valuation model were: risk free interest
rate - 4.45%, expected life - 5 years and expected volatility - .328.

          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 is as follows:

6.       Income taxes (Cont'd)

         At December 31, 1998,  the Company had net operating  losses for income
tax  purposes of  approximately  $3,821,000  which are  available  to be carried
forward to future periods.  These losses expire in the following  years:  1999 -
$194,000,  2000 - $294,000, 2001 - $545,000, 2002 - $569,000, 2003 - $1,077,000,
2004 - $544,000 and 2005 - $1,711,000.

         At December 31, 1998,  the  following  oil and gas tax  deductions  are
available to reduce future taxable income,  subject to a final  determination by
taxation authorities.

Canada

Drilling, exploration and lease acquisition costs                     $9,965,000
Earned depletion                                                       1,975,000

Share issue costs                                                        175,000

United States

Exploration and lease acquisition costs                                 $819,000

         The tax benefits  attributable  to the above  accumulated  expenditures
will not be  reflected  in the  consolidated  financial  statements  until  such
benefits are realized.

         Under U.S.  GAAP,  the  provisions for income taxes would have differed
for the reasons set out below:

         In February  1992,  the United States  Financial  Accounting  Standards
Board issued  Statement No. 109,  "Accounting  for Income Taxes",  effective for
fiscal years  beginning  after  December 15, 1993.  Under U.S. GAAP, the Company
would have been required to adopt Statement No. 109 commencing July 1, 1993.

         Under Statement No. 109, the liability method is used in accounting for
income  taxes.  Under this  method,  deferred  tax assets  and  liabilities  are
determined  based on differences  between  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.  Under
Canadian GAAP and previously  under U.S. GAAP,  income tax expense is determined
using the deferral method.  Deferred tax expense is based on items of income and
expense that are reported in different years in the financial statements and tax
returns and are  measured at the tax rate in effect in the year the  differences
originated.

6.       Income taxes (Cont'd)

         The following schedule summarized the Company's income tax recovery and
deferred  tax asset under U.S.  GAAP.  If  Statement  No. 109 was  adopted,  the
Company  would have had a deferred  tax asset  which  primarily  represents  the
excess of  available  resource  deductions  for  income  tax  purposes  over the
recorded  value of oil and gas  properties  together with  operating and capital
income tax loss  carryforwards.  These amounts are expected to be recovered from
the  production of current oil and gas reserves when the  Kotaneelee  litigation
expenditures  have ended.  As certain of the resource  deductions are restricted
and the  operating  loss  carryforwards  are  subject  to  expiration,  there is
considerable  risk  that  certain  of these  deductions  will  not be  utilized.
Accordingly,  the  Company  would have  established  a  valuation  allowance  to
recognize this uncertainty.  Income taxes computed in accordance with U.S. GAAP,
would have resulted in a credit to the provision of taxes.

7.        Line of credit

          The Company has a line of credit with a Canadian  chartered bank which
provides  for a loan of  $500,000.  The line of credit  provides  for a $125,000
operating  loan and  $375,000  for  letters of credit as part of the  directors'
indemnification  agreements. The interest rate on borrowing is at 3/4% above the
bank's prime lending rate. The line of credit is subject to annual review and is
secured by a general  assignment of accounts  receivable  and an  undertaking to
provide security in the form of assignment of future working interest proceeds.
No drawings were made under this line during 1998 or 1997.

8.       Litigation

         The  Company,  which has a 30%  interest in the  Kotaneelee  gas field,
believes  that the  working  interest  owners in the field  have not  adequately
pursued the  attainment of contracts for the sale of Kotaneelee  gas. In October
1989 and in March 1990,  the Company  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  Company  claims  that the  Defendants  breached  either a contract
obligation  and/or a  fiduciary  duty owed to the Company to market gas from the
Kotaneelee  gas field when it was  possible to so do. The Company  asserts  that
marketing  the  Kotaneelee  gas was  possible  in 1984 and  that the  Defendants
deliberately failed to do so. The Company seeks money damages and the forfeiture
of the Kotaneelee gas field.  The Company  presented  evidence at trial that the
money damages sustained by the Company were approximately $100 million.

         In  addition,  the  Company  has  claimed  that the  Company's  carried
interest  account should be reduced  because of improper  charges to the carried
interest account by the Defendants.  The Company claims 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 Company claims that  expenditures  made to repair and rebuild the
field's dehydration plant should not have been necessary had the facilities been
properly  constructed and maintained by the Defendants.  The  expenditures,  the
Company claims,  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.



<PAGE>


8.       Litigation (Cont'd)

         The Company claims that production from the field should have commenced
in 1984. At that time the field's carried interest account was approximately $63
million.  The Company  claims  that by 1993 at least $34 million of  unnecessary
expenses  had been  wrongfully  charged to the  carried  interest  account.  The
Company's 30% share of these expenses would be approximately $10.2 million.  The
Company  further  claims 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. At present,
the Company does not expect to receive revenues before the year 2000, based on a
price of Cdn. $1.28 per mcf and current production rates.

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

         The parties to the litigation have conducted  extensive discovery since
the filing of the claims.  The trial began on  September 3, 1996 and the Company
completed the  presentation  of its case against the Defendants on September 16,
1998. Based upon newly discovered evidence, the Company filed a new claim during
May 1998 that the Defendants failed to develop the field in a timely manner. The
Company is unable to estimate the time necessary to conclude the litigation.

Matters Ancillary to Kotaneelee Litigation

         In its 1989  statement  of  claim,  the  Company  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
Company will be assessed a processing fee on gas throughput.

         With respect to the first issue, the Company maintains that no interest
should  accrue  on the  account  and the  Defendants  have  not  contested  this
position.  With  regard to the second  issue,  the  Company  maintains  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.



<PAGE>


8.       Litigation (Cont'd)

         On January 22, 1996, the Company settled two claims outstanding against
the Company in the Court of Queens Bench, Calgary,  Alberta,  which related to a
suit brought against  AlliedSignal  Inc.  ("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  Company  for any costs in  connection  with the  Kotaneelee
Litigation.  The Company 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.

         In 1991,  Anderson  Exploration  Ltd.  acquired  all of the  shares  in
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 Canadian
lawsuit.  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.

         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,  the Company
estimated  that  taxable  costs,   assuming  a  twelve  month  trial,  could  be
approximately  $1.5  million  and noted  that the judge in complex  and  lengthy
trials has the discretion to increase an award.

         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 matters before the Court. In addition,  the Company believes
that the trial  will  extend  well  beyond  its  original  time  estimates  and,
therefore, potentially assessable costs would increase accordingly.



<PAGE>


8.       Litigation (Cont'd)

         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 it
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.  A cost award
against the Company  could be of sufficient  magnitude to  necessitate a sale of
Company assets or a debt or equity financing to fund such an award. There are no
assurances that any such sale or financing would be consummated.

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

9.       Related party transactions

         In 1991,  the Company  granted  interests to  certain of its  officers,
employees,  directors, counsel and consultants amounting to an aggregate of 7.8%
of any and all benefits to the Company  after  expenses  from the  litigation in
Canada  relating to the  Kotaneelee  gas field.  The Company has reserved a 2.2%
interest in such net  benefits  for  possible  future  grants to persons who may
include officers and directors of the Company.

         Mr. Heath, a director of the Company,  has royalty interests in certain
of the Company's oil and gas properties,  (present and past) which were received
directly  or  indirectly  through  the  Company.  The  Company  and  third-party
operators and/or owners of properties made payments  pursuant to these royalties
for the benefit of Mr. Heath totaling U.S. $8,324,  $11,158 and $10,844 in 1998,
1997 and 1996, respectively.

11.      Year 2000 date issue

         The Year 2000 Issue arises  because many  computerized  systems use two
digits rather than four to identify a year. Date-sensitive systems may recognize
the year 2000 as 1900 or some other date,  resulting in errors when  information
using year 2000 dates is processed.  In addition,  similar problems may arise in
some systems which use certain dates in 1999 to represent something other than a
date. The effects of the Year 2000 Issue may be experienced before, on, or after
January 1, 2000,  and if not  addressed,  the impact on operations and financial
reporting may range from minor errors to significant systems failure which could
affect an entity's  ability to conduct  normal  business  operations.  It is not
possible  to be certain  that all aspects of the Year 2000 Issue  affecting  the
Company,  including  those  related to the efforts of customers,  suppliers,  or
other third parties, will be fully resolved.

            accordance with the provisions of Article 2.4 above.

<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

the same manner as though such  provisions  were  contained  in this  Agreement.
Where there is any conflict  between the  provisions  of this  Agreement and the
Operating Procedure or the Accounting Procedure the provisions of this Agreement
shall prevail and in the case of any conflict  between the  Operating  Procedure
and the  Accounting  Procedure the provisions of the Operating  Procedure  shall

      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

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

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

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.

      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.

then  such  person  shall  agree to pay all  costs and  expenses  in  connection
therewith.

      assigned  except  liabilities  which arose prior to the  agreement to make
      such assignment;

      (c) the  Joint  Operator  agreeing  to make such  assignment  shall not be
      released  from  any  obligation  which  arose  prior  to the  date  of the
      agreement to accept such assignment;

      (d) such assignment  shall be without warranty of title of the interest of
      the assigning party;

      (e) all the  terms  of this  Agreement  shall  continue  to  apply to such
      interest  as  among  the  Joint  Operators  who have  not  assigned  their
      interest;

      (f) where it is necessary to obtain the consent of any person other than a
      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

      The term "joint  property"  as herein used shall be  construed to mean the
      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

      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.

             for the  reason of  repairs or other causes  beyond the  control of
             operation.


<PAGE>

      In  connection  with  overhead  charges,  the status of wells  shall be as
follows:

      (1)   In-put or key wells shall be included  in overhead schedule the same
            as producing oil wells.

      (2)   Producing gas wells shall be included  in overhead schedule the same
            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

      (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

      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
      warehouse  shall  be  assessed  on new and  used  material  and  equipment

                  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
deemed to be a well not capable  of production  in commercial  quantities within
the meaning of the said Agreement dated May 28, 1959.

5.       Except as expressly provided herein,  nothing herein contained shall be
deemed to amend, modify,  enlarge or reduce  the obligation  of H-S  to  drill a
minimum of  five (5)  exploratory  wells  as  otherwise  provided  in  the  said
Agreement dated May 28, 1959,  nor the obligation to incur the total cost of the
exploratory  program referred to in  paragraph 3.1 (B)(b) of Article III of said
Agreement.

6.       Except as herein modified and supplemented,  the said  Agreement  dated
May 28, 1959,  is hereby  ratified and  confirmed and shall remain in full force
and effect.

7.       This agreement  shall enure to  the benefit of  and be binding upon the
parties hereto and their respective successors and assigns.

         IN WITNESS WHEREOF the parties hereto have caused this instrument to be
executed as of the date first above written.

<PAGE>

parties to the Main Agreement and/or their assignee successors in interest.

ARTICLE II

C-M-O Carried Interest

2.1 When this  Schedule "D" has become  effective  pursuant to Clause 8.2 of the
Main Agreement as amended,  C-M-O's  interest in the Permits shall thereafter be
in the nature of a fifty percent  (50%)  carried  interest and the Permits shall
become  carried  interest  lands.  C-M-O's  said  interest  in  the  Permits  is
hereinafter  referred to as "the C-M-O  carried  interest"  or "C-M-O's  carried
interest".

2.2 The parties  hereto hereby  transfer and set over among them all such right,
title  and  interest  as shall  required  to vest in  C-M-O  the  C-M-O  carried
interest.  No formal transfer need,  however, be made of the registered interest
of the parties in the said Permits for this purpose.


<PAGE>

2.3 C-M-O's  carried  interest  shall be and  constitute  the right of C-M-O (in
addition  to the  further  rights  hereinafter  set forth) to  receive,  and the
obligation  of A-D-P to pay to C-M-O fifty  percent (50%) of the amount by which
the  operational  receipts from each Block on and after April 1, 1966 exceed the
operational  costs from each respective  Block on and after April 1, 1966. A-D-P
covenants  and agrees to pay to C-M-O in cash the  amounts (if any) due to C-M-O
from time to time under this Clause 2.3 with respect to each Block.

2.4 Subject to the provisions of the Operating  Procedure  relating to a party's
right to decline  to  participate  in an  operation  and the right to  surrender
pursuant to the Operating Procedure, A-D-P shall from April 1, 1966 maintain the
Permits and the leases or other  documents  of title  derived  therefrom in good
standing,  shall pay all lease rentals, make all required deposits or guarantees
with the Department,  perform all exploratory  work and development  work on the
Permits,  and pay any costs or  expenses  whatever  with  respect to the further
holding,  managing,  exploration and development of the Permits (whether held in
permit  or  lease  stage or  howsoever).  This  Clause  shall  not  apply to any
expenditure  by  C-M-O  with  respect  to  any  operation  instituted  by  it as
hereinafter  provided,  nor shall it prevent a full settlement of accounts among
the parties hereto as at March 31, 1966, with respect to matters  accruing up to
and including March 31, 1966.


<PAGE>

2.5 The  "operational  receipts"  from a Block for the  purposes  of Clause  2.3
hereof and wherever used herein shall mean the cumulative  total of all receipts
(other than refunds of deposits with the Department) by A-D-P on and after April
1, 1966 from the Block,  including the proceeds of sale of petroleum  substances
from the Block and any refund of or cash  contribution  toward  any  operational
costs  charged to that Block and any proceeds  realized upon the disposal of any
machinery  or equipment  charged to the  operational  costs for that Block,  and
including,  without limiting the generality of the foregoing, any receipts which
the  Operator  would be  required  to  credit  to the  joint  account  under the
Accounting Procedure.

2.6 The  "operational  costs" with  respect to a Block for the purpose of Clause
2.3 hereof and  wherever  used  herein  shall mean the  cumulative  total of all
expenditures made by A-D-P on and after April 1, 1966 on or with respect to that
Block, including,  without limiting the generality of the foregoing,  all permit
renewal fees, lease rentals,  exploratory costs,  development costs,  production
costs and marketing costs with respect to that Block, and including all lessor's
royalties  and the  overriding  royalties to which the permits in that Block are
subject as  described in Schedule "A" to the Main  Agreement;  provided  that no
cost  shall be charged as an  operational  cost  unless it can be charged to the
joint account under the Accounting Procedure (or, with respect to the cost of an
independent  operation,  could be so charged if the operation were for the joint
account).

2.7 When the operational receipts with respect to a Block exceed the operational
costs with respect to that Block,  C-M-O shall  become  entitled to its share of
such excess,  notwithstanding that with respect to the other Block or Blocks the
operational costs may still exceed the operational receipts.


<PAGE>

2.8 If any  operational  costs are  incurred  which cover more than one Block in
such a manner that a division  of such costs on an acreage  basis would not be a
fair division  thereof or if it is difficult or impossible to determine to which
Block the  operational  costs should be  attributed,  A-D-P shall  allocate such
costs  according to its best bona fide estimate of the value or  relationship to
each Block of the costs thus incurred.

ARTICLE III

Accounting for the C-M-O Carried Interest

3.1 On and from April 1, 1966,  C-M-O's rights to receive statements and to make
audits with respect to the C-M-O  carried  interest  shall be the same as though
C-M-O were a joint operator (non-operator) under the Accounting Procedure.

3.2 A-D-P agrees to maintain  accounts and render  statements  for each Block so
that the  operational  receipts  and the  operational  costs  may be  separately
determined for each Block and so reported to C-M-O.  Paragraph 2 of Schedule "C"
shall be followed in rendering statements.

3.3 Where a statement of the C-M-O carried  interest account for any month shows
an amount due C-M-O,  payment of the amount due C-M-O shall be forwarded  either
with such statement or not more than 15 days thereafter.

3.4 C-M-O shall not be obligated to repay to A-D-P any moneys paid on account of
the C-M-O carried interest with respect to a Block if the operational  costs for
that Block again exceed the operational receipts for a Block after a period when
the reverse was the case.


<PAGE>

ARTICLE IV

Right to Access and Information, Etc.

4.1  Except  as  may  be  expressly  hereinafter  provided,  C-M-O's  rights  to
information  and data with respect to all  operations on the Permits  (including
that  received  in trade which is related to the  Permits)  shall be the same as
though such  operations were being carried on for the joint account of C-M-O and
A-D-P under the Operating Procedure; and, with the said exception, C-M-O's right
of access to the Permits while  operations are being conducted  thereon shall be
the same as if C-M-O were participating therein as operations for the said joint
account.

4.2 With the  consent of all parties  hereto,  A-D-P or any member or members of
the A-D-P group shall have the right to trade seismic data obtained from or with
respect to the Permits.  Such data shall  otherwise be kept  confidential by the
parties.

4.3 Canada Southern alone or its assigns shall represent C-M-O in exercising the
rights of C-M-O under Clause 4.1 hereof while the C-M-O  carried  interest is in
effect.

ARTICLE V

Independent Operations While Carried Interest in Effect

5.1 For the  purposes  of the  C-M-O  carried  interest  it shall be  immaterial
whether  operational costs and operational  receipts are incurred or received by
one or more members of the A-D-P group, should independent operations be carried
out by less than all the members of the A-D-P group  pursuant to Clause N of the
Operating Procedure (or howsoever).


<PAGE>

5.2 C-M-O shall have the right to propose the drilling,  deepening or re-working
of a well  (hereinafter  called "the  operation"),  on any lands  subject to the
C-M-O carried interest which have been selected under lease from the Permits, in
the same manner and under the same  conditions  as provided in Clause N.2 of the
Operating  Procedure;  provided  that the  approval of a drilling  or  deepening
operation in a budget of the A-D-P group shall not prevent C-M-O from  proposing
an operation under the said Clause N.2 unless A-D-P undertakes to C-M-O to carry
out the  operation  approved in the said budget within the time proposed in such
budget (or, if earlier, within six months). No such operation may be proposed by
C-M-O  unless  upon the basis that  either all  members of the C-M-O  group will
participate  therein or that the participating  members of the C-M-O group shall
bear at least fifty  percent (50%) of the cost of the  operation.  While C-M-O's
interest in a Block is a carried interest and the operation proposed by C-M-O is
with  respect to that Block,  A-D-P  agrees that A-D-P shall act as one party in
electing  whether to participate in the operation so proposed by C-M-O. If A-D-P
does elect so to  participate,  the operation shall be carried out for the joint
account of A-D-P and C-M-O, and C-M-O shall pay in cash its share of the cost of
the operation in the same manner as a Joint Operator.  The share of the costs of
the operation paid by C-M-O shall not be operational costs. Otherwise,  however,
the well and the lands upon which the  operation  is  carried  out shall  remain
subject to the C-M-O carried interest.


<PAGE>

5.3 If A-D-P elects not to participate  in an operation  proposed by C-M-O under
Clause 5.2  hereof,  and if C-M-O  carries out the  operation,  C-M-O shall upon
completion  of the  operation be entitled to the same penalty  under Clause N of
the  Operating  Procedure  as if C-M-O had  proposed  the  operation  as a Joint
Operator. Any cash paid by A-D-P to participate in the operation with respect to
a development well under Subclause N.2(c) (ii) of the Operating  Procedure shall
not be  operational  costs  except to the extent of the amount which A-D-P would
have borne had A-D-P  initially  participated  with C-M-O in the  operation.  If
A-D-P or one or more  members of the A-D-P group elects by payment of cash under
Subclause N.2(c) (ii) of the Operating Procedure to participate in the operation
with respect to a  development  well after the operation has been carried out by
C-M-O,  the spacing  unit of that well  (subject to Clause N.3 of the  Operating
Procedure)  shall cease to be subject to the C-M-O carried interest and shall be
held by the parties  participating  therein as joint lands for their own account
pursuant to the Operating Procedure.

5.4 Any  acreage  which is  forfeited  to C-M-O by reason of the  provisions  of
Clause N of the  Operating  Procedure,  where A-D-P does not  participate  in an
operation  proposed by C-M-O,  shall cease to be subject to this Schedule "D" or
to the Main  Agreement  (except  as to  lease  selection  under  Clause O of the
Operating Procedure).

5.5 Except as provided in Clauses 5.3 and 5.4 hereof,  all lands in a Block upon
which  C-M-O has  conducted  the  operation,  whether or not A-D-P  participated
therein, shall continue to be subject to the C-M-O carried interest.


<PAGE>

5.6 If at the time C-M-O gives  notice of election to convert the C-M-O  carried
interest to a working  interest as  hereinafter  provided any  operations are in
progress  pursuant to Clause E of Schedule  "B" on the  Permits,  C-M-O shall be
deemed to have elected to participate in those operations.  If, however,  notice
of a  proposed  operation  has been  given  under  Clause  N.2 of the  Operating
Procedure and the period for replying to such notice has not expired,  the party
proposing  the  operation  shall give C-M-O a new notice  thereof under the said
Clause N.2 when notice of C-M-O's  conversion of the C-M-O carried interest to a
working  interest  has been  received;  provided  that the  proposing  party may
proceed with the operation,  if it so wishes,  without awaiting C-M-O's election
with respect to participation  in the operation,  in which event the election of
C-M-O shall be treated as retroactive  for determining  costs and  participating
interests.

ARTICLE VI

Work Credits

6.1 For the purposes of the C-M-O carried  interest the operational  costs shall
be  calculated  as if no  grouping  of  permits  or leases  (for the  purpose of
permitting  the allocation of work credits as provided by statute or regulation)
had occurred, whether work credits earned elsewhere are applied to lands subject
to the C-M-O carried interest or whether work credits earned on lands subject to
the C-M-O carried interest are applied to other lands.


<PAGE>

6.2 While the C-M-O  carried  interest is in effect with  respect to one or more
Blocks,  A-D-P  shall by April 30 of each year  after  1966  submit to C-M-O its
proposed allocation of work credits among the Blocks.  Unless C-M-O gives notice
to A-D-P  within  30 days that it is  dissatisfied  with  such  allocation,  the
allocation  shall be deemed  acceptable.  If C-M-O gives such notice the parties
will attempt to arrive at a  mutually-agreeable  allocation.  If either party is
dissatisfied  with the progress of the negotiations in this respect it may elect
to have the  available  work  credits  allocated  among the Blocks on an acreage
basis.  Allocations  of work credits  under this  Article  shall be binding upon
C-M-O if and when it elects to convert the C-M-O  carried  interest to a working
interest.

6.3 Work credits  earned by  operations  by C-M-O under  Article V hereof shall,
except to the extent  that they may be applied to reduce  costs with  respect to
lands forfeited to C-M-O under Article V hereof or lands held jointly as working
interests  by C-M-O  and A-D-P  under the said  Article  V, be  treated  as work
credits earned by A-D-P and shall be allocated under Clause 6.2 hereof.

6.4 Upon the  surrender of any lands out of a Block to another  party or parties
to this Agreement the then existing unused work credits applicable to that Block
shall be deemed to have been allocated equally among each acre in that Block.

ARTICLE VII

Conversion of Permits to lease

7.1 A-D-P  shall  maintain  all the said  Permits in permit  form until at least
their respective anniversary dates in 1967.


<PAGE>

7.2 A-D-P shall  maintain in permit form until the earliest  permit  anniversary
date  falling  in the year  1969 all the  Permits  except  the  total of

         (a)      the Permits or parts thereof which may  meanwhile  be required
                  to be converted to lease by the Department; and

         (b)      the  Permits  or  parts  thereof  which  A-D-P  may  meanwhile
                  surrender to C-M-O;

         and

         (c)      Permit areas totaling not more than 400,000 acres in area.

7.3 A-D-P  shall  maintain  in permit  form until at least the  earliest  permit
anniversary  date  falling in the year 1970 all the Permits  except the total of

         (a)      the Permits or parts thereof which may meanwhile be required
         to be converted to lease by the Department; and

         (b)      the  Permits  or  parts  thereof  which  A-D-P  may  meanwhile
         surrender to C-M-O;

         and

         (c)      Permit areas  totaling not  more than  550,000 acres  in area,
         inclusive of 7.2 (c) areas above.

7.4 A-D-P  shall  maintain  in permit  form until at least the  earliest  permit
anniversary  date  falling in 1971 all the  Permits  except the total of

         (a)      the Permits or parts thereof which may  meanwhile  be required
         to be converted to lease by the Department; and

         (b)      the  Permits  or  parts  thereof  which  A-D-P  may  meanwhile
         surrender to C-M-O;

         and

         (c)      Permit  areas  totaling  not more than  650,000 acres in area,
         inclusive of 7.2 (c) and 7.3 (c) areas above.


<PAGE>

7.5 Subject to the foregoing  Clauses of this Article VII, A-D-P may convert the
remaining  Permits  to lease as A-D-P  sees  fit and  C-M-O  shall  Join in such
conversion and shall accept the selection of leases proposed by A-D-P;  provided
that if C-M-O has prior to the time of any such lease  selection  converted  the
C-M-O  carried  interest  to a  working  interest,  Clause  O of  the  Operating
Procedure shall apply to the lease selection.

7.6 If, while the C-M-O carried interest is in effect, A-D-P does not propose to
take  leases of the  maximum  area which may by law be leased  from any  permit,
A-D-P shall so advise C-M-O not less than 30 days before the lease  selection is
to be  forwarded  to the  Department.  C-M-O shall then have the right to select
further  leases for C-M-O's  account  from that  permit up to the  maximum  area
permitted by law,  provided that any such selection by C-M-O shall not cause any
change in the  lease  selection  already  made by A-D-P.  C-M-O  shall  promptly
furnish to A-D-P the funds required to take such C-M-O leases.

         For the  purpose of this Clause 7.6 A-D-P shall be deemed to have taken
the "maximum  area" if it selects  leases with the intention of  converting  the
entire permit to lease,  notwithstanding  that its manner of lease selection may
not result in the maximum  acreage which it might be possible to select from the
permit if the selection were made in some other manner.

7.7 If any  selection of leases must be made in the names of all parties  hereto
or if such  leases  must be  issued  in the  names of all  parties  hereto or to
parties  not  owning  the  beneficial  interest  therein  in the same  manner as
provided  herein  or in the Main  Agreement,  the  parties  shall  execute  such
assignments  and  documents  as may be necessary to transfer the leases to their
beneficial owners.


<PAGE>

7.8 All such  leases  selected  by A-D-P from the  permits  (except  for C-M-O's
account  under  Clause 7.6  hereof)  shall  continue  to be subject to the C-M-O
carried  interest  with respect to the Block in which the  respective  permit is
contained,  unless C-M-O has converted  the C-M-O carried  interest to a working
interest in that Block prior to the said lease selection.

7.9 All acreage of the permits  which is not  selected  under lease by A-D-P for
A-D-P's account under the foregoing provisions of this Article shall cease to be
subject  hereto or to the Main  Agreement,  except as provided  in Article  VIII
hereof.

7.10 In selected  leases from  Permits  1137 and 2301,  it is  recognized  that,
unless  otherwise  agreed  with the  owners of the south half of each of Permits
1137 and 2301,  the said owners  shall be entitled to select  one-half the total
acreage  which  may be  acquired  under  lease  out of  Permits  1137  and  2301
respectively,  such  selection to be made from acreage in the south half of each
of the said two permits.  By mutual agreement with such owners,  lease selection
may be made across the  boundaries of the north and south half of each or either
of the said two permits, in which case the portion of such leases falling within
each respective half-permit shall be assigned to the owners of that half-permit.

7.11 A-D-P is hereby given the right to arrange with the Department for a common
renewal  date for all or some of the  Permits,  as a matter  of  convenience  of
administration  and  programming of work  requirements.  With respect to each of
those Permits for which such common renewal date is approved by the  Department,
the  "anniversary  date" shall thereafter for all purposes hereof be such common
renewal date.


<PAGE>

7.12 To the extent  that A-D-P is  required  under this  Article VII to keep the
said Permits in permit form and therefore to make  deposits with the  Department
as a guarantee for the  performance  of exploratory  work,  A-D-P agrees that it
will in fact expend on exploratory  work on the Permits an amount  sufficient to
cause to be refunded all such  deposits made and to be made in the calendar year
1966.  A-D-P  agrees to commence on or before  February 1, 1967 the  exploratory
work  necessary to ensure refund of the said deposits made and to be made in the
calendar year 1966.

ARTICLE VIII

After-Acquired Lands

8.1 If any  Permit is  surrendered  to the  Department  by both  C-M-O and A-D-P
(other than for the mere purpose of selecting oil and gas leases therefrom), the
area of the surrendered Permit shall cease to be subject in any way hereto.

8.2 If any lease selected from a Permit is surrendered to the Department by both
C-M-O and A-D-P (except for  replacement  or  amendment)  the area of that lease
shall cease to be subject in any way hereto.

8.3 If any lease is  acquired by A-D-P or C-M-O in such  circumstances  that the
acquiror is expressly  required  hereunder  to offer an interest  therein to the
other party and such other party  declines such offer,  the lease shall cease to
be in any way subject hereto.


<PAGE>

8.4 If, prior to March 31, 1973,  any lands  (hereinafter  called "the  acquired
lands") all or not less than twenty-five  (25%) percent of which fall within the
original  area of a Permit or Permits  and any part of which lie within one mile
of the lands then subject to the C-M-O carried  interest  (excluding lands which
become  subject to the C-M-O  carried  interest  by reason of this  Clause  8.4)
should be for sale,  and provided  the  acquired  lands are not lands which have
ceased to be subject  hereto by reason of Clauses  8.1,  8.2 or 8.3 hereof,  the
parties shall take the following action:

         (a) If no well is then being  drilled by A-D-P on lands  subject to the
         C-M-O  carried  interest,  and if A-D-P  acquires  any of the  acquired
         lands,  A-D-P shall advise  C-M-O what  parcels of the  acquired  lands
         A-D-P has acquired. C-M-O shall then have the right for a period of ten
         (10)  days  after  receipt  of such  advice  to  elect  to have all the
         acquired  lands which have been acquired by A-D-P included in the lands
         subject to the C-M-O carried interest.

         (b) If A-D-P is then  drilling  a well on lands  subject  to the  C-M-O
         carried interest,  and if A-D-P  advises  that the well is being  timed
         for a Crown sale (and such is the case)  A-D-P  shall have the right to
         withhold from C-M-O all information  and derrick floor  privileges with
         respect to the well until after the Crown sale,  and the offer to C-M-O
         to have any  acquisition  by  A-D-P at  the Crown sale  included in the
         lands subject to the C-M-O carried  interest shall be made to C-M-O not
         later than ten (10) days  after the Crown sale,  accompanied by all the
         information which A-D-P had  with respect to the  said well at the time
         it submitted its  bid for  the posted  lands.  Subclause (a) shall then
         apply to such offer. If, however,  A-D-P does not propose to bid at the
         Crown sale where a well is timed for the sale as aforesaid, A-D-P shall


<PAGE>

         so advise C-M-O not later than forty-eight  (48) hours before the Crown
         sale and  give C-M-O  all  the  information  (including  derrick  floor
         privileges)  available  to  A-D-P from the said  well at that time.  If
         C-M-O then  bids at the  Crown sale  and  acquires  any  of  the posted
         lands, such acquisition  shall cease to be subject in any way hereto.

         (c) C-M-O agrees  that,  except as provided  in  Subclause  (b),  C-M-O
         will not bid  independently on  any posted lands  in which  it  must be
         offered a carried interest under Subclause (b) of this Clause 8.4.

8.5 If prior to March 31, 1973,  and while it holds the C-M-O  carried  interest
position in a Block,  C-M-O  should  acquire  from other than A-D-P any lands in
that Block (or which lie at least  twenty-five  (25%) percent in that Block) and
provided  such lands have not then ceased to be subject  hereto by reason of the
provisions  of Clauses 8.1 to and  including  8.4 hereof,  C-M-O shall  promptly
offer such lands to A-D-P at C-M-O's cost  thereof;  and if A-D-P  promptly pays
for such  lands,  they  shall  become  subject  to the  C-M-O  carried  interest
hereunder in that Block.  Such offer shall be accompanied by all the information
which C-M-O has with respect to the acquisition and shall be open for acceptance
by payment for ten (10) days (only) after the receipt thereof.

         This Clause 8.5 shall  not apply to  leases  selected for  C-M-O's  own
account from the Permits under Clause 7.6 hereof.


<PAGE>

         If C-M-O  elects to have any  acquired  lands made subject to the C-M-O
carried  interest  pursuant to Clause 8.4 hereof,  or should any  acquisition of
lands  be  taken  over by A-D-P  from  C-M-O  pursuant  to this  Clause  8.5 the
acquisition  thus made subject to the C-M-O carried  interest  shall be added to
the  Block in which are  situated  or partly  situated  the lands  which are the
subject  of such  acquisition.  Should  such  acquisition  include  lands in two
Blocks, both of which are subject to the C-M-O carried interest, the acquisition
(and the cost thereof) shall be divided  between the respective  Blocks in which
they lie. If such division causes a parcel to be divided between two Blocks, the
acquisition cost of that parcel shall be divided on an acreage basis.

         Any such  acquisition  thus  added to a Block  shall  thereupon  become
subject  to all the  provisions  hereof  (including  the  right  of  conversion)
relating to the C-M-O carried interest lands in that Block.

         The  operational  costs for the Block to which is added any acquisition
made subject to the C-M-O carried  interest  under Clause 8.4 or this Clause 8.5
hereof shall be increased by the bonus consideration and other costs to A-D-P of
the acquisition thereof, and in the case of a bonus consideration there shall be
added to the  operational  costs for the Block six (6%) percent per annum of the
said bonus consideration until such time as either (i) the operational  receipts
for that  Block  have  exceeded  the  operational  costs  (including  such bonus
consideration and interest) for that Block or (ii) the operational receipts from
the acquired  parcel have  exceeded the said bonus  consideration  plus interest
with respect to that parcel, whichever time is earlier.

8.6 No party hereto shall, by use of a parent company, subsidiary,  affiliate or
associate  company or any company nominee or person employed by or controlled by
such party, evade any of its obligations under this Article VIII.


<PAGE>

8.7 Should C-M-O convert the C-M-O carried interest to a working  interest,  the
provisions  of this Clause 8.7 shall apply  thereafter  in lieu of the foregoing
provisions of this Article VIII, (except Clauses 8.1, 8.2 and 8.3 hereof,  which
shall remain in full force and effect):

         (a) If prior to March 31, 1973, any lands,  all or not less than 25% of
         which lie within an area bounded by lines drawn (1) outside of a Permit
         area (2) parallel to the respective  boundaries of that Permit area and
         (3) one mile from the respective  boundaries of that Permit,  should be
         posted for Crown sale (as to the  petroleum  and/or  natural gas rights
         thereunder),  the parties  hereto  shall meet to attempt to arrive at a
         joint bid for such posted lands or for one or more parcels thereof.  If
         the parties do not agree upon a joint bid,  each of the  parties  shall
         disclose to the other parties the bid it proposes to make at such Crown
         sale for the  respective  parcels  upon which it  intends to bid.  If a
         joint bid is agreed upon, it shall be submitted by the Manager-Operator
         for the  account  of the  parties,  each of whom shall be  required  to
         provide its pro rata share of the moneys  required to be tendered  with
         such bid. If a joint bid is not agreed upon and any party is successful
         in  acquiring  at such Crown sale a parcel or parcels at a price  which
         varies  more  than 5% from the  amount  the  acquiror  revealed  as its
         proposed bid for such parcel or parcels, the acquirer shall be required
         to  offer a pro  rata  share of the  acquisition  at cost to the  other
         parties  hereto.  The said offer shall  remain open for a period of ten
         days only (or for 48 hours only if a well is then being drilled  within
         one mile of the parcel or parcels subject to the offer).


<PAGE>

         (b) If any party hereto should  acquire any interest  in lands to which
         Subclause (a)  of this  Clause 8.7 would  apply if such  lands were the
         subject of a Crown sale,  but such acquisition  is made by way of other
         than Crown sale, the acquiror shall offer participation at cost in such
         acquisition  to the other parties hereto.  Subclause (a) shall apply as
         to acceptance of such offer.

         (c) For the purposes of this Clause 8.7,  references  to parties hereto
         shall refer to the individual parties to this agreement rather  than to
         the A-D-P  group and the C-M-O group as such;  and  a  "pro rata share"
         shall mean pro rata to the following percentages:

               Canada Southern     -  45.00%

               Magellan            -   4.00%

               Oil Investments     -   1.00%

               Alminex             -   2.50%

               Pan American        -  25.00%

               Dome                -  15.00%

               Provo               -   7.50%

         (d) Any party hereto who  (in default of its obligation so to do)  does
         not comply  with the foregoing provisions  of this Clause as to bidding
         at the Crown sale shall in any event be  obliged  to offer to the other
         parties hereto an interest  in every acquisition  at such Crown sale in
         the same manner and extent as above  provided for a party hereto who is
         required to offer an interest in its  acquisition  to the other parties
         hereto.

8.8      The provisions of this Article shall  not apply to any lands within the
south half of Permit 1137 and the south half of Permit 2301.

ARTICLE IX

Gas Plants and Gathering Systems

9.1 If A-D-P during the period in which C-M-O holds the C-M-O  carried  interest
in the Blocks or any of them as  aforesaid,  proposes to construct gas gathering
systems and a gas processing  plant for the purpose of putting  natural gas from
that Block or those Blocks in a marketable  state or otherwise to process it for
the  removal  of  liquids  and/or  sulphur,  A-D-P  shall  advise  C-M-O of such
proposal,  giving C-M-O the cost estimates and proposed  specifications  of such
gathering systems and plant.  C-M-O shall have ninety (90) days after receipt of
such information to advise A-D-P whether C-M-O elects to participate in the said
gathering  systems and plant as a fifty (50%) percent working interest owner. If
C-M-O elects so to  participate it shall be required to bear and pay in cash its
fifty (50%)  percent  share of the cost of  construction  of the said  gathering
systems and plant.

9.2 If C-M-O does not elect so to  participate,  A-D-P may proceed to  construct
the gathering  systems and the plant for A-D-P's  account and risk.  Whether the
said  plant and gas  gathering  systems  are  constructed  by C-M-O and A-D-P or
solely by A-D-P,  the cost of construction,  operation and maintenance  thereof,
and the receipts and revenues  therefrom,  shall not be added to the operational
costs or the  operational  receipts  respectively  for the purposes of the C-M-O
carried  interest,  but the  following  provisions  of this Article  shall apply
thereto:

         (a) The said gathering systems and plant shall be owned and operated by
         the parties hereto who bear the cost thereof as provided in this Clause
         9.2  and as a  project  separate  and  apart  from  the  ownership  and
         operation  of the  lands  subject  hereto.


<PAGE>

         (b) The owners of the  said gathering systems  and plant shall have and
         are hereby exclusively  granted the right to gather and process the gas
         produced from the lands subject hereto and to the Main  Agreement which
         are (or are to be) served by the said gathering  systems and plant, and
         to charge for such gathering and  processing a fee or charge which will
         limit  cumulative  net revenue to the said owners of the said gathering
         systems and plant  in accordance with  the principles  expounded in the
         Alberta  Public  Utilities  Board's  Shell-Jumping  Pound  decision  of
         December, 1961, assuming the following in applying such principles:

                  (a)      a rate of return of 8 1/2% on rate base;
                  (b)      a 50/50 debt - equity ratio;
                  (c)      a 6% interest rate on debt;
                  (d)      a 11% return on equity capital;
                  (e)      an income tax  allowance to be computed as 50% of the
                           taxable  income  consisting of the allowed  return on
                           equity and debt  capital  plus income tax  allowance,
                           less interest on debt capital;
                  (f)      depreciation on a unit of throughput  basis (that is,
                           the  factor to be used in  determining  the amount of
                           depreciation  to be allowed in any year is arrived at
                           by dividing the  throughput of the gathering  systems
                           and plant by the remaining  recoverable  gas reserves
                           at the beginning of the period under review);
                  (g)      and provisions  for  working  capital equal to 25% of
                           annual operating costs.

         (c) The  operational  costs for a Block shall include the fee or charge
         which is made under  Subclause  (b) for gathering  and  processing  gas
         produced from that Block while C-M-O holds the C-M-O interest  therein.


<PAGE>

         (d) If any plant to which this  Clause 9.2  applies is also used in any
         calendar  year to process gas from sources other than the lands subject
         hereto  (and the right to process  such other gas is  expressly  hereby
         given) then all costs (including depreciation) of processing gas at the
         plant in that  year,  and the rate  base for that  year,  shall for the
         purposes of  determining  the charge or fee to be made under  Subclause
         (c) of this Clause 9.2 be divided among such other gas and gas from the
         lands subject  hereto in proportion  to the  respective  volumes of gas
         processed from such other lands and from the lands subject hereto.

         (e) If the said  gathering  systems  or  any  part  thereof are used to
         transport such other gas,  an allocation of  the costs of the gathering
         systems or  parts thereof  so used  shall  be  made in  the same manner
         mutatis  mutandis  in  proportion  to  the  respective  volumes  of gas
         transported in the calendar year.

ARTICLE X

Proposed Surrender of Carried Interest Lands

10.1 If A-D-P  proposes  to  surrender  to the  Department  any lands  which are
subject  to  the  C-M-O  carried  interest,  and  if the  lands  proposed  to be
surrendered  are then held in  permit  form,  A-D-P  shall  give  notice of such
proposed  surrender  not less than 90 days before the next  ensuing  anniversary
date of the  permit  (or  respective  permits,  if more  than  one)  which it is
proposed to surrender.  Unless within 60 days after receipt of such notice C-M-O
requests in writing an assignment to C-M-O of the lands which A-D-P has proposed
to  surrender,  C-M-O shall be deemed to have elected to join in such  surrender
and shall in fact join therein.


<PAGE>

         If C-M-O  requests  such  assignment,  A-D-P shall  assign to C-M-O the
interest which A-D-P had proposed to surrender, and such interest shall cease to
be subject hereto or to the Main Agreement.

10.2 If A-D-P  proposes  to  surrender  to the  Department  any lands  which are
subject to the C-M-O carried interest but which are not then in permit form, the
provisions of Clause P of the Operating Procedure shall apply to such surrender,
for which purpose  A-D-P and C-M-O shall each act as one party.  If the interest
proposed to be  surrendered  is assigned to C-M-O pursuant to the said Clause P,
that interest shall cease to be subject in any way hereto.

ARTICLE XI

Operations Generally

11.1 With respect to lands subject to the C-M-O carried interest C-M-O shall not
be  "Joint  Operators"  under  the  Operating  Procedure,  except  as  otherwise
expressly  provided herein.  C-M-O shall be entitled to vote,  however,  for the
appointment of a Manager Operator under the Operating  Procedure as if the C-M-O
carried  interest were a working  interest;  provided that the Manager  Operator
while the C-M-O  carried  interest  is in effect  shall be a member of the A-D-P
group unless A-D-P otherwise unanimously agrees or unless no member of the A-D-P
group  fills the  position  of  Manager  Operator  for a period  of thirty  (30)
consecutive days.

11.2 If C-M-O fails to exercise its vote to join in the appointment of a Manager
Operator as aforesaid,  the Manager  Operator  shall be appointed by A-D-P,  and
each member of the A-D-P group shall have a percentage vote for this purpose pro
rata to its  working  interest as if the  working  interests  of the A-D-P group
totaled 100%.


<PAGE>

ARTICLE XII

Conversion of C-M-O Carried Interest

12.1 With  respect to each Block,  C-M-O shall have the right at any time during
the term hereof to convert the C-M-O  carried  interest in that Block to a fifty
(50%) percent  undivided working interest therein by paying to A-D-P one-half of
the amount by which the operational  costs for that Block exceed the operational
receipts  for  that  Block;  provided  that  if at the  effective  date  of such
conversion the operational receipts exceed the operational costs with respect to
that Block, such conversion may be made without any payment to A-D-P.

12.2 Upon converting the C-M-O carried interest in a Block to a working interest
as provided in Clause 12.1 and making the payment, if any, due thereunder, C-M-O
shall,  without  further  formality  or  assignment,  have and hold an undivided
one-half  working  interest  in all  wells,  batteries,  dehydrators,  treaters,
compressors,  tanks, flow lines, and equipment and material of all kinds in that
Block, the cost of which had been paid as operational costs or incurred prior to
the date hereof  (subject to Article IV of the said amending  agreement of April
1, 1966).

12.3 Upon  converting  the C-M-O  carried  interest  to a working  interest in a
Block,  C-M-O shall then become and be subject to all the rights and liabilities
of a Joint Operator under the Operating Procedure with respect to that Block.

12.4 C-M-O shall give A-D-P written notice of its intention to convert the C-M-O
carried  interest  to a  working  interest  in any  Block  or  Blocks,  and such
conversion  shall become  effective on the first day of the calendar month which
falls next after the  notice,  provided  the  payment,  if any,  due A-D-P under
Clause 12.1 hereof is made.  Such payment  will be adjusted as of the  effective
date as soon as a statement to that date is prepared  and  submitted to C-M-O by
A-D-P.


<PAGE>

12.5 Where any lands  cease to be subject to the C-M-O  carried  interest,  that
fact  shall not  affect  the  operational  receipts  and the  operational  costs
theretofore credited or charged to the account of the C-M-O carried interest.

ARTICLE XIII

Conversion By Less Than All C-M-O

13.1 Each member of the C-M-O group shall have the right  separately  to convert
that  member's  share of the C-M-O carried  interest to a working  interest in a
Block or Blocks.  The working  interest  obtained  upon such  conversion by such
member  (hereinafter  called "a converting member") shall be that shown opposite
the converting member's name below, namely:

         Canada Southern                    -      45.00%

         Magellan                           -       4.00%

         Oil Investments                    -       1.00%

13.2     In making such separate conversion the converting member

         (1) Shall for the  purposes  of Clause 12.1 hereof pay A-D-P a fraction
         of  one-half  the  amount by which the  operational  costs  exceed  the
         operational receipts, which fraction shall be

                  (i)      in the case of Canada Southern     -   45/50ths

                  (ii)     in the case of Magellan            -    4/50ths

                  (iii)    in the case of Oil Investments     -     1/50th

         (2)  Shall for the  purposes  of Clause  12.2  hereof  obtain a working
         interest in wells and other items listed in Clause 12.2 hereof equal to
         the same fraction as in Subclause 13.2(1) hereof of one-half the entire
         working interest therein.


<PAGE>

13.3 After any such conversion is made by less than all the members of the C-M-O
group, the percentage carried interest held by each non-converting member of the
C-M-O group shall be that shown  opposite  its name where first listed in Clause
13.1 hereof. A converting  member shall bear no share of the burden of the C-M-O
carried interest held by the non-converting members of the C-M-O group.

13.4 The payment (if any) made under Clause 12.1 hereof by a  converting  member
of the C-M-O group shall not be considered as  operational  receipts,  nor shall
any  receipts  accruing  to or  expenditures  made  by a  converting  member  be
considered as operational receipts or operational costs for the purposes of this
agreement.

13.5 Unless and until such time as Canada  Southern is a converting  member with
respect to a Block, a converting member who proposes an operation under Clause N
of the Operating  Procedure  shall not be entitled to proceed with the operation
unless all members of the C-M-O group participate  therein. If less than all the
members of the A-D-P  group  participate  in any such  proposed  operation,  the
participating  members of the A-D-P  group shall bear pro rata the same share of
the cost of the  operation  as if all  members of the A-D-P group had elected to
participate  in the  operation  and  shall be  entitled  to the  entire  penalty
accruing  from the  non-participating  member or  members  of the  A-D-P  group,
subject to the C-M-O carried interest still held by the  non-converting  members
of the C-M-O group.

13.6 A converting member of the C-M-O group shall not thereby become a member of
the A-D-P group.


<PAGE>

13.7 For the  purposes of Article  VIII hereof  with  respect to  after-acquired
lands, a converting member of the C-M-O group (provided all members of the C-M-O
group  are not  then  converting  members)  shall,  as  between  A-D-P  and such
converting  member,  be  considered  a member of the C-M-O group except that any
interest  acquired by A-D-P which is to be offered to C-M-O shall,  with respect
to the converting  member only, be offered at cost as a working  interest rather
than as a carried interest.

13.8 For the purposes of Clause 8.5 hereof,  if a converting member acquires any
lands which if  acquired  by C-M-O would be offered to A-D-P under that  clause,
the converting member shall offer A-D-P such acquisition except for a percentage
thereof equal to the  converting  member's  percentage  working  interest in the
Permits. If A-D-P accepts the offer, A-D-P shall then, as provided in Clause 8.4
hereof,  offer to include the  acquisition  by A-D-P in the lands subject to the
C-M-O carried interest.

ARTICLE XIV

C-M-O Rights Re Sale of Production

14.1 Subject to Article IX of this Schedule "D", while C-M-O holds the C-M-O net
carried  interest in a Block C-M-O shall have the right to dispose of 50% of the
petroleum  substances  produced  and saved from that Block  (except  the portion
thereof  required  for use in  operations  on  that  Block),  and to  make  such
contracts for the sale of the said 50% of such petroleum substances as C-M-O may
wish,  provided  such  contracts  shall be at arm's  length (or on terms no less
favourable to C-M-O than if made at arm's  length) and provided  such  contracts
are not at terms less  favourable than those which A-D-P offers C-M-O in writing
before  such  contracts  are made for the same.  The rights of C-M-O  under this
clause may be exercised separately with respect to oil and natural gas.


<PAGE>

l4.2 The  rights  of C-M-O  under  Clause  14.1 may be  exercised  only upon the
condition  that the  proceeds  of all such sales  shall be assigned to A-D-P and
made payable  directly to A-D-P to be applied towards the  operational  receipts
for the  respective  Block  from  which the  petroleum  substances  so sold were
produced,  unless and until A-D-P  agrees in writing to the  contrary  after the
operational receipts exceed the operational costs for that Block.

<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

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

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
         which would  incorporate  the terms hereof and  incorporate  also those
         provisions of the Existing Agreements which remain in effect.

                  With respect to the Block II lands the Existing  Agreements as
         hereby amended shall continue in full force and effect.


XIV.     PRIOR AGREEMENTS TERMINATED

                  That Agreement entered into by Canada Southern Petroleum Ltd.,
         Dome  Petroleum  Limited and Provo Gas Producers Ltd. dated January 10,
         1963 is hereby  terminated.  Furthermore,  that Letter  Agreement dated
         June 24, 1959 entered into by Canada Southern, Home Oil Company Limited
         and Signal Oil and Gas Company is hereby also terminated.


XV.      ALLOCATION OF CREDITS

                  Any grouping or work credits  generated by the drilling of the
         Test Well shall be shared equally between Columbia and the Farmors.


XVI.     INDEMNITY

                  Columbia undertakes to indemnify and hold harmless the Farmors
         from and against any or all claims,  demands,  suits or actions arising
         out of Columbia's operations hereunder.


XVII.    INSURANCE

                  Columbia will comply with the requirements contained in Clause
         I  of  the  HS-CMO  Agreement   relating  to  insurance  and  workman's
         compensation.   The  limits  of  insurance  required  therein  will  be
         increased to reflect current costs.

XVIII.   ALLOCATION OF COSTS

                  The parties agree that all items of cost under this  agreement
         (including  without  limitation  intangible  drilling  and  development
         expenses,  depletion,  lease rentals,  dry hole costs and depreciation)
         shall be allocated to the party which contributed the funds therefore.


         If the above sets out your  understanding of the terms of our agreement
please so indicate  by signing and  returning  the  attached  copy hereof to the
writer at your earliest convenience.

         When accepted by all parties this letter will form a binding  agreement
and continue in effect until replaced by more formal documentation.

         It is our understanding  that in executing this Letter Agreement Canada
Southern is acting on its own behalf and is authorized  also to act on behalf of
its partners, Magellan Petroleum Corporation and Oil Investments, Inc.

         (b) Farmee shall have the right to make any changes or  alterations  in
the seismic program referred to in subclause (a) hereof, PROVIDED THAT Farmor is
relieved of its obligations  respecting  participation  in these  programs.  All
allowable  expenditures  and the benefits  accruing  from  participation  in the
aforesaid survey programs shall accrue to Farmee.

6.       FARMEE'S DRILLING PROGRAM

         Farmee  has  agreed  with  Farmor  to cause a  drilling  program  to be
conducted in the vicinity of the Permits, consisting of the following:

         (a) If seismic work conducted  during the Spring of 1972  establishes a
drill site on Permit No.  484,  200 or more feet  structurally  higher  than the
Hecla  J-60 then a well will be  commenced  not later  than the Fall of 1973 and
drilled to a depth of 5,000 feet, to Paleozoic formation or production whichever
occurs first.

         (b) A well in the Drake  Point  area west of Block V at a  location  of
Farmee's choice to be commenced on or before the first day of April, 1974.

         (c) A well on a location of Farmee's choice on the Isachsen  Penninsula

         (d) Additional  seismic will be conducted on Permit No. 688 during 1972
on the  Louise  Anticline  and if 300  feet  or more of  structural  closure  is
established  at 8,000 feet or a  shallower  depth  then a well at a location  of
Panarctic's  choice will be  commenced by the Spring of 1974 and drilled to test
the stratigraphic  equivalent of the gas productive sand found in the Kristoffer
Bay G-06 and King Christian D-18A wells.

7.       SUPPLYING INFORMATION TO FARMOR

         (a)  Farmee  shall  supply  immediately  Farmor  with   all information
acquired  by it from work  performed  on the  Permits or off permit work that is
part of a program  conducted  on the  Permits.  Farmor shall not be obligated to
participate in the costs of any  exploratory  work  (excluding  drilling) on the

Notwithstanding  that  Farmor  may  not be  participating  in the  cost  of such
exploratory work other than drilling, as aforesaid, Farmor shall nevertheless be
entitled  to  receive  from  Farmee  copies  of all  basic  data  (exclusive  of
interpretation) derived therefrom,  provided that the provisions of clause 33 of

         (a) The right of conversion reserved to the Farmor under the provisions
of this clause may be exercised as to any one or more of the Blocks described in
Schedule "A" hereto.

         (b) Subject to clause 9 hereof,  the Farmor shall be entitled by notice
in writing to Farmee given at any time prior to the earliest anniversary date in
1977 of any permit in said Block to convert  its 50%  working  interest to a 30%

         (c) The  effective  date for  conversion  of the rights of the Farmor's
interest  from a working  interest  to a carried  interest  shall be the date on
which notice is given by the Farmor as aforesaid.

         (d) Upon the effective date of any such conversion, then the provisions
of Schedule  "C" shall  apply to the Block or Blocks with  respect to which such
conversion  is effected  whereupon  the  provisions  of Schedule "B"  (Operating
Agreement) shall have no application to such Block or Blocks, except as provided
in Schedule "C".

9.       WELL PROPOSALS

         If Farmee  proposes a well on any Block on which Farmor has not elected
to convert its interest to a carried interest,  pursuant to Clause 8 hereof, and
prior to the final date for election to so convert Farmor shall, notwithstanding
the  provisions  of Clause 8 hereof,  exercise its right to elect to convert its
interest  in the Block on which the well is  proposed  to be drilled to a thirty
(30%) percent carried interest within thirty (30) days of the date of receipt of
notice  proposing  the well.  If Farmor fails to elect to so convert  within the
said  thirty  (30) day  period,  it will have no further  right to elect on such
Block and such Block shall continue to be subject to the Operating Agreement.

10.      HEMBDT OVERRIDE

         (a) The parties  acknowledge that the Permits are subject to the Hembdt

respective share of the Hembdt override on all Permits  remaining subject to the
Operating  Agreement  which is hereby  charged  to the joint  account  under the
Operating  Agreement.  If Farmor  elects to convert  its  working  interest to a
carried  interest  pursuant  to the  provisions  of clause 8  hereof,  then with
respect to those  Permits in which the  interest has been so  converted,  Farmee
shall pay the Hembdt  royalty and all sums so paid shall be expenses  chargeable

         (b) Farmor shall supply  Farmee  forthwith  upon the  execution of this
Agreement with the agreement or other documents setting forth the particulars of
the Hembdt override.

due to strikes,  lockouts, fire, tempest, or acts of God of the Queen's enemies,
or any other cause (whether  similar or dissimilar to those  enumerated)  beyond
its  control,  but lack of  finances  shall in no event be  deemed to be a cause
beyond a  party's  control;  and in the case of any  obligation  contained  in a
Permit, the rights of the parties hereto with respect to force majeure shall not
exceed those granted to the Permitee named therein.

12.      FURTHER ASSURANCES

affect such party's rights with respect to any other of future breach.

21.      PERFORMANCE OF PERMITS BY FARMEE

         Except as otherwise provided in this Agreement, Farmee shall, as of the

         the other party notifies proposing party in writing of agreement to the
         drilling of the well in accordance with the proposal  notice,  Operator
         shall  drill same on the terms set out in the  proposal  notice and the
         well shall be deemed to be a well drilled for the joint  account of the
         parties.

(b)      If, upon the expiration of sixty (60) days from receipt of the proposal
         notice,  the other  party does not agree in writing to the  drilling of
         such  well  (and  failure  to advise  proposing  party  shall be deemed
         non-agreement),  proposing  party may,  prior to the  expiration of one
         hundred  and twenty  (120) days from  receipt of the  proposal  notice,
         commence  the  drilling of such well and  thereafter  drill same to the
         proposed depth. If such well is not commenced  within the aforesaid one
         hundred and twenty  (120) day period,  the well  proposed  shall not be
         drilled without a new proposal notice.


<PAGE>

(c)      Operations  pursuant to  subclause  (b) hereof  shall be  performed  by
         proposing  party and such well shall be drilled,  completed,  capped or
         abandoned  at the sole risk and  expense of  proposing  party  and,  if
         abandoned,  the  provisions  of Clause 24 hereof shall not apply to the
         other party.

Agreement of 1-1-75:        Exploratory  well defined as  a well 2 or more miles
                            from producing  well.  Penalty for not participating
                            in exploratory well is 6 N.W.T. sections.

(d)      If production of petroleum substances is  encountered  in such well and
         the same is capable of such production and is not abandoned,  then such
         well shall be operated by proposing party for its sole account, and all
         proceeds of production therefrom shall accrue to proposing  party until
         proposing party receives from the proceeds of production from such well
         Three Hundred  (300%) percent of all drilling and  completion  costs of
         such well,  together  with One Hundred (100%) percent of all  operating
         and any other costs incurred with respect to such  well  subsequent  to
         the "on production" date (as set by the applicable governmental agency)
         to the  date  of  recoupment  by  proposing  party  of  such  drilling,
         completion,  and operating and other  costs (the total of the foregoing
         costs is  hereinafter  referred to  as "penalty  expenses").  All  such
         costs are to be computed and charged in accordance with the  Accounting
         Procedure.


<PAGE>

(e)      During  the period in which  proposing  party is  recouping the penalty
         expenses,  it shall  supply  to  the  other  party  a monthly statement
         setting forth all costs  incurred  in  the operation of such well,  the
         revenues  received from the sale of  production therefrom and a current
         statement each month  setting forth a  comparison  of the total of such
         revenues  to the total of  the penalty expenses  incurred to such date.
         If proposing party  receives  out  of  the  proceeds  of production the
         penalty  expenses,  it shall,  within twenty (20) days of such receipt,
         give written  notice to the other party of its receipt of same,  and on
         or before  the  expiration  of thirty  (30) days from  receipt  of such
         written notice,  the  other  party  shall  have  the  right  to  advise
         proposing  party in writing of its  election  to  participate  in  such
         well.  If the other  party so elects to participate  it shall be deemed
         to have participated as of the date the penalty expenses were recovered
         by proposing  party.  Failure of the  other  party  to advise proposing
         party in writing within the time hereinbefore specified of its election
         to participate shall be deemed an election not to participate.

(f)      If the other party elects  to participate in such well  as in subclause
         (e) hereof provided,  Operator shall assume operation  thereof  and the
         well shall  be construed as a well being operated for the joint account
         of the parties from and after  the  effective  participation  date.  In
         such event each  party shall participate  in the well  to the extent of
         its participating  interest.


<PAGE>

(g)      Until such  time  as  any  well  drilled  pursuant  to this  clause  is
         abandoned  or is operated  as a well for the  account  of  both  of the
         parties,  as hereinbefore provided, proposing party shall own the well,
         the equipment  pertaining  thereto  and  all  production  of  petroleum
         substances  therefrom  excepting  production  from  such  well  of  any
         petroleum and/or natural gas that is being produced, or that is capable
         of being  produced,  from any other well or wells the  production  from
         which is attributable  to any  horizons or  formations  of that spacing
         unit on which the well drilled by proposing  party is  located.  At the
         request of proposing  party,  the other party shall execute and deliver
         to proposing  party all documents  as  proposing  party  may reasonably
         request to further evidence the foregoing.

(h)      Proposing party  shall initially  pay and  bear for its own account all
         royalties and taxes applicable to the production obtained from a well
         drilled by it pursuant  to this  clause,  and the other  party shall be
         under no  liability whatsoever for same, provided that all royalties so
         paid shall be first deducted before deducting the penalty expenses.

(i)      All wells drilled on the Lands shall be drilled at a rate substantially
         the same as that prevailing in the area in which the  proposed  well is
         to be located.

(j)      If proposing party is unable to recover from the proceeds of production
         the penalty expenses, it shall own all material, equipment and supplies
         placed or  installed by  it at its sole  expense in the  well or on the
         Lands in connection therewith,  but  if  such  material,  equipment and
         supplies have a salvage value,  less the  estimated  cost  of salvaging
         (such  value  to  be  determined  in  accordance  with  the  Accounting
         Procedure),  in  excess  of  the  unrecovered  amount  of  the  penalty
         expenses,  such excess shall be owned by both parties in  proportion to
         their participating interests.


<PAGE>

(k)      Proposing  party shall indemnify and save harmless the other party from
         and against all actions,  suits,  claims  and demands whatsoever by any
         person or persons  whomsoever in respect of any loss,  injury or damage
         or  obligation to compensate  arising  out  of or  connected  with  the
         operations  carried  on by proposing  party pursuant to this clause and
         prior to the operation of  such well by Operator for the joint  account
         of the parties.

(l)      Proposing  party shall supply to the other  party,  on  or  before  the
         expiration  of ninety (90) days from the rig  release  date  or  the on
         production date of any well  drilled  by it,  whichever  is the  later,
         all factual  data  obtained  from  such  well  covering  the  drilling,
         testing and completion,  capping  or  abandonment,  operations  and the
         other party  shall  be  entitled  to  have  access,  after  the  period
         hereinbefore  specified,  to  all  samples  and  cores  taken from such
         well.

(m)      The foregoing  provisions of this clause shall, mutatis mutandis, apply
         to any deepening,  reworking  and  plugging-back  operations,  with the
         under-noted explicit restrictions:

         (i)      Unless  otherwise  mutually  agreed,  no  well  producing,  or
                  capable  of  producing,   petroleum   substances   in   paving
                  quantities shall be deepened, reworked or plugged-back;

         (ii)     The period for  accepting the proposal  notice shall be forty-
                  eight (48) hours when a rig is present on the  location;

         (iii)    The period for commencing deepening,  reworking  or  plugging-
                  back operations shall be ninety-six (96) hours from receipt of
                  the proposal notice when a rig is present on the location.

         II. Obligation Wells:

         For the purposes of this clause,  an obligation well is a well which is
required to be commenced and drilled on the Lands under the terms of the Permits
or under the terms of any  regulations or statutes  applicable  thereto and that
failure to  commence  and drill the same will result in  forfeiture  of all or a
portion of the Lands.

(a)      If a notice of the  obligation is given,  the party who receives notice
         of the obligation shall notify the other party hereto of the accrual of
         an  obligation  to   commence  the  drilling   of  an  obligation  well
         immediately upon receipt by it of notice or information that such  well
         is required to be commenced.  If the parties hereto, within thirty (30)
         days of both parties having such notice,  do  not  elect  to drill such
         obligation well as a joint account  well or either of them do not elect
         to drill such obligation well pursuant to the provisions of subclause I
         hereof, the Operator shall forthwith:

         (i)      Attempt to secure release ofthe obligation bythe party to whom
                  the obligation is owed; or

         (ii)     Attempt by  settlement or compromise  to make other reasonable
                  arrangements in lieu of drilling  the obligation well with the
                  party to whom the obligation is owed; or

         (iii)    Attempt to have the obligation  performed by an outside  party
                  without  privity  to  this   Operating  Procedure  upon  terms
                  agreeable to the parties hereto.


<PAGE>

(b)      If none of the foregoing  alternatives  can be agreed upon and put into
         effect  within thirty (30) days of  the  expiration  of  the  aforesaid
         thirty (30) day period, and one of the parties hereto desires to drill,
         the party desiring to drill  the  said  well  (hereinafter  called  the
         "drilling party")  may proceed  to do  so at  its sole cost,  risk  and
         expense  provided  it  commences  the  drilling  of  such well at least
         thirty-one  (31)  days  prior  to  the date upon which the well must be
         drilled to satisfy the obligation,  and continues with due diligence to
         complete the drilling thereof.  Any such well shall conform to the then
         existing well spacing program. On completion or abandonment of any such
         well,  the party  which did  not participate  in the  drilling thereof,
         shall assign or transfer to the drilling party all of its  interest  in
         and to that  portion of the Lands which,  under the terms of the Permit
         in question or the applicable regulations or statutes,  as the case may
         be,  would have been  surrendered  or forfeited if such obligation well
         had not been drilled.

         In the event the period of time between the date that both parties have
         notice of the  requirement  to drill the  obligation  well and the date
         within which such well must be drilled is less than the period of  time
         allowed above to comply with the foregoing procedures, then each of the
         thirty (30) day periods referred to above shall be reduced  accordingly
         with a view  to maintaining  such  procedures  but  decreasing the time
         limits within which they must be effected.

(c)      If neither of the parties hereto is desirous of drilling the obligation
         well,  the parties  hereto shall join in taking the steps  necessary to
         surrender  those  portions  of  the  Lands  which  are  required  to be
         surrendered by the terms of the Permit in question or by the applicable
         regulations or statutes.


<PAGE>

(d)      If the obligation may not be avoided by surrender of the Lands in whole
         or in part and failure to perform the same would  support an action for
         specific  performance  or  damages,  then  if  none  of  the  foregoing
         provisions apply and if the parties hereto cannot  mutually  agree upon
         the nature, location, extent and cost of a program necessary to satisfy
         such  obligation,  then  notwithstanding  anything  elsewhere  in  this
         Operating  Procedure contained,  Operator  shall have the sole right to
         determine such program  and  shall  notify  the other  party  hereto in
         writing  of  the  nature,  location,  extent  and  anticipated  cost of
         conducting such program.  In such event,  and  notwithstanding anything
         elsewhere in this Operating Procedure contained,  both  parties  hereto
         shall  participate  in and shall bear their proportionate  share of the
         cost thereof to  the same extent  as if and to  the intent and  purpose
         that such program were in fact  conducted  by mutual  agreement of both
         parties in accordance with the provisions of this Operating Procedure.

7.       MAINTENANCE OF THE PERMITS:

         Except as otherwise provided in this Operating Procedure,  Operator, on
behalf  of both  parties,  shall  comply  with  all the  expressed  and  implied
covenants  and  conditions  contained  in the  Permits  and shall do all  things
necessary to maintain  the Permits in full force and effect but,  subject to the
provisions  of Clause 6 hereof,  Operator  shall not drill any well on the Lands
unless and until the parties have agreed to such drilling.


<PAGE>

8.       GENERAL ACCOUNTING:

         (a) Subject to subclause (b) hereof,  Operator shall  initially pay and
charge to the account of the parties all costs and expenses of whatsoever nature
made or incurred with respect to any operations  whatsoever on,  maintenance of,
and production from the Lands, and all such costs and expenses shall be borne by
the parties in accordance with their respective participating interests, and the
method of handling the  accounting  with respect  thereto shall be in accordance
with the provisions of the Accounting Procedure.

         (b) Any costs or expenses made or incurred  pursuant to the  provisions
of Clause 6 hereof  shall be borne  solely by the party  which made or  incurred
same  pursuant  to said  provision,  and all  taxes  based on or  calculated  on
production of petroleum  substances  from the Lands shall be borne by that party
which was entitled to said  petroleum  substances in the  proportion in which it
was entitled to same.

9.       ADVANCES:

         Operator may, at its option and from time to time, require both parties
to advance their  respective  shares of the estimated  costs and expenses of all
operations  of  whatsoever  nature  carried  out by  Operator  on  behalf of the
parties. If Operator elects to so require any advance it shall, during the first
fifteen (15) days of any month, request in writing that Non-Operator advance its
estimated share for the month of any costs and expenses  authorized by agreement
of the parties or otherwise permitted under Clause 5 herein, and if so requested
Non-Operator  shall pay its share of such  estimated  monthly costs and expenses
within fifteen (15) days of receipt of the request from Operator.

         The accounts  between the parties  shall be adjusted to actual costs by
Operator in the month's statement  following the month in which the actual costs
are ascertained.


<PAGE>

10.      OPERATOR'S LIEN:

         Operator  shall  have a first  and  prior  lien on all  rights  and the
interest of Non-Operator in and to the Lands,  the Permits and in any production
obtained  therefrom  and the material and  equipment  thereon,  and shall have a
right of set-off against monies  otherwise  payable to Non-Operator  pursuant to
this Operating  Procedure,  to secure the payment by Non-Operator of any amounts
owing by it to Operator  pursuant to the terms of this Operating  Procedure.  If
Non-Operator  does not pay to Operator  its share of such monies  within  thirty
(30)  days  after  demand,  Operator  shall  have the right to  enforce  payment
thereof,  together with interest  thereon at Six (6%) percent per annum,  in any
manner in which it is entitled either pursuant to this Operating  Procedure,  or
at law, or both.  The lien and other rights herein  granted to Operator shall be
in addition to and not in substitution for any other rights or remedies Operator
may have with respect to the  non-payment of any amount owing by Non-Operator to
Operator.

11.      OWNERSHIP OF PRODUCTION:

         (a) Each party shall own and, at its own expense,  may take in kind and
separately  dispose  of for its  own  account  its  proportionate  share  of all
petroleum  substances produced and saved from all wells operated on the Lands on
behalf of the parties, subject, however, to deduction from each party's share of
production its proportionate  share (where applicable) of all lessors' and other
royalties  paid in kind and to the terms and  provisions  of the Permits and the
Accounting  Procedure  and to the right of Operator to use such of the petroleum
substances as may be required for the  development and operation of the Lands on
behalf of the parties and in preparing  and treating such  petroleum  substances
for marketing purposes, and exclusive of production unavoidably lost.


<PAGE>

         (b) If  Non-Operator  at any time and from time to time fails to notify
Operator of the  arrangements it has made to take in kind or separately  dispose
of  its   proportionate   share  of   production,   Operator  may  purchase  the
Non-Operator's share of production at prices not less than the prevailing market
price  for  products  of like  kind and  quality,  or sell the same to others at
prices  not  less  than  those  which  Operator  receives  for its own  share of
production  in an arm's length  transaction  for a monetary  consideration  to a
purchaser  other  than an  affiliate  of the  Operator.  If  Operator  is itself
purchasing Non-Operator's share of production, the right is revocable at will by
written notice to Operator. If Operator is selling Non-Operator's  proportionate
share of production to others,  the right is revocable by Non-Operator by giving
written notice to be effective  within a time not less than the period of notice
which  Operator  must give in order to terminate  its sale  arrangements.  In no
event  shall   Operator   enter  into  any  sales   contract   with  respect  to
Non-Operator's  share of  production  which is for a period  greater  than  that
usually  entered into in the area or for a period of one (1) year,  whichever is
the lesser.

         (c) If Operator purchases and/or sells the share of production to which
Non-Operator is entitled as aforesaid,  Operator shall deliver to  Non-Operator,
on or before the last day of each and every calendar month, a complete statement
or statements properly verified,  including Statutory  Declarations if requested
by  Non-Operator,  with  respect to the quantity and kind of that portion of the
petroleum  substances  produced  and saved from the Lands  during  the  previous
calendar month  attributable  to the interest of  Non-Operator.  Operator shall,
with each such  statement,  pay to  Non-Operator  the proceeds  from the sale of
Non-Operator's portion of such production subject to all deductions of royalties
applicable thereto.


<PAGE>

         (d) Any  market  available  to  Operator  shall  be  shared  by it with
Non-Operator to the intent and purpose that Non-Operator  shall not be obligated
to store its participating interest in petroleum substances produced,  except to
the proportionate  extent that petroleum  substances  produced are so stored for
lack of market.

12.      PRE-COMMENCEMENT INFORMATION TO NON-OPERATOR:

         Prior to commencing any well  on behalf of the parties,  Operator shall
furnish to Non-Operator:

15.      LOGGING INFORMATION TO NON-OPERATOR:

         During the  drilling of any well on behalf of the parties and upon such
well reaching the proposed depth, Operator shall run all log surveys agreed upon
among the  parties  hereto,  prior to the  drilling  of such well to provide the
optimum  evaluation  possible  of the  horizons  penetrated.  In addition to the
foregoing,  Operator  shall run such other logs as may be agreed  upon among the
parties subsequent to the drilling of any such well.  Operator shall supply Non-
Operator with copies as requested of each log so run.

16.      VELOCITY SURVEYS:

         (a) Operator,  on its own behalf and at its own expense,  in accordance
with good oilfield and established  modern and scientific  practices,  may run a
velocity survey in any well drilled on behalf of the parties.

subclause  (a) hereof,  Non-Operator,  on its own behalf and at its own expense,
including rig time and any other costs relating to such survey which would be in
excess of normal  drilling  or  operating  costs,  may run such  survey with the
written  consent of  Operator,  and in so doing  Non-Operator  shall  proceed in
accordance with good oilfield and established modern and scientific practices.

         (c) If a velocity  survey is run by Operator  pursuant to subclause (a)
or by Non-Operator  pursuant to subclause (b) hereof,  the party not bearing the
costs  of  same  may   obtain  a  copy   thereof,   together   with  all   basic
non-interpretative  geological  and  geophysical  data  (including  check shots)
obtained  from the well in which such  velocity  survey is run, by paying to the
other party  one-eighth (1/8) of the costs thereof (which costs include rig time
costs). The party running the velocity survey shall,  notwithstanding  Clause 33
hereof,  have the  exclusive  right to trade  and sell the  results  of the said
velocity  survey to any third party or parties.  Any party which runs a velocity
survey shall  indemnify  the other party to this  Operating  Procedure  from and
against all actions,  causes of action,  claims and demands for all loss, injury
or damages such other party may incur or suffer by reason of the exercise of the
rights herein granted.

17.      COMPLETION INFORMATION TO NON-OPERATOR:

         Upon the completion of any well drilled on behalf of the parties,
Operator shall supply to Non-Operator:

         (a)      copies as requested of any directional,  temperature,  caliper
                  or other well surveys or oil, gas, water or other analyses
                  made;

         (b)      samples as requested of at least one (1) quart of water and/or
                  petroleum  substances  other than natural gas  recovered  from
                  each test if  Operator  does not make  analyses  of such water
                  and/or petroleum substances other than natural gas;

         (c)      a complete summary of the drilling and completion;

         (e)      all production  information  and  other  data  relating to the
                  completion of the well.

18.      ADDITIONAL TESTS:

         In  addition  to  its  rights  in  connection  with  velocity  surveys,
Non-Operator shall have the right at its sole cost, risk and expense to make any
other test or survey in any well drilled by the Operator for the joint  account,
provided that Non-Operator shall not make any test or survey in any such well in
the event that the hole is in  unsatisfactory  condition  for such  purposes  as
determined  by  the  Operator  and  provided  further  that  Non-Operator  shall
indemnify  and save  harmless  the other party hereto from and against all loss,
damage,  or cost  which  such  other  party  may  incur or  suffer  by reason of
Non-Operator exercising the rights herein granted.

19.      ACCOUNTS AND INFORMATION:

         Operator shall:

         (a)      at all times keep true and correct books, records and accounts
                  showing  all  operations  carried  on  and  the  quantity  and

may be required to be done in order to determine  the  gasoline  content of gas,
the  gravity  of oil,  the amount of water  content  and the amount of any other
foreign substances  contained in any petroleum  substances,  or the qualities of
any other  substances  shall be taken,  done and  performed  by  Operator by any
method or process  generally  recognized in the industry where the work is to be
done  and is  considered  as  reliable  and in  accordance  with  good  oilfield
practice.

21.      OPERATIONAL PRACTICES:

         Operator shall carry on all operations in a proper manner in accordance

terms  and  provisions  of the  Permits  and this  Operating  Procedure,  and in
compliance  with all applicable  laws,  rules,  orders and  regulations but with
reasonable  allowances  having  regard to the  adverse  and  unusual  conditions
encountered in operations in Arctic areas.

of insurance,  if requested,  evidencing full  compliance with the  requirements
outlined above.  The policy and  certificates  shall include the Non-Operator as

the policies.

         (f)  Each  party  which  carries  on any  operations  pursuant  to this
Operating  Procedure shall maintain  insurance to the limits not less than those

24.      ABANDONMENT OF WELLS:

         (a) If  either  party  desires  to  abandon  any  well  being  drilled,
deepened,  reworked or operated  pursuant to this  Operating  Procedure,  or one
which is  suspended,  it shall give to the other  party  written  notice of same
(hereinafter called "the abandonment notice").  The party not wishing to abandon
shall, within forty-eight (48) hours of the receipt of the abandonment notice in
the case of a well on which a drilling  rig is located,  and within  thirty (30)
days of the receipt of the  abandonment  notice in all other  cases,  notify the
party wishing the abandon of its intention not to abandon, and shall, as soon as
reasonably  possible,  tender to the party  desiring  to  abandon a sum of money
equal to the interest of the party desiring to abandon in the fair salvage value
of all salvable  materials  and  equipment  attributable  to the well,  less the
estimated cost of salvaging the same,  such value  determined in accordance with
the  provisions  of  the  Accounting  Procedure.   Failure  to  respond  to  the
abandonment  notice shall be deemed an election to  participate  in the proposed
abandonment.


<PAGE>

         (b) Upon  receipt of notice from the party not wishing to abandon,  the
abandoning party shall execute and deliver all necessary  documents to convey to
the party  tendering such notice its entire interest in and to the said well and
the casing and equipment therein,  together with all of its rights in all future
production  therefrom  which may be produced  from the interval  from which such
well last produced,  provided  however it is specifically  understood and agreed
that such  conveyance  shall  exclude  production  from  such well of  petroleum
substances or any of them that are being produced,  or that are capable of being
produced,   from  any  other  well  or  wells,  the  production  from  which  is
attributable  to any  horizons or  formations  of that spacing unit on which the
well subject to the abandonment notice is located.

         (c) Upon the execution and delivery of the conveyance by the abandoning
party,  the well and spacing unit covered  thereby  shall cease to be subject to
this  Operating  Procedure  and the  abandoning  party  shall  be  released  and
discharged from all obligations  thereafter  accruing with respect to such well,
but  such   conveyance   shall  not  release  the  abandoning   party  from  its
proportionate  share of any  obligation  or  liability  which ought to have been
performed or may have accrued prior to such conveyance.

         (d) In the event both  parties  desire to abandon the well which is the
subject of the  abandonment  notice,  then  Operator  shall  abandon  such well,
provided  however that,  where such well was drilled by one of the parties only,
pursuant to  provisions  of Clause 6 hereof,  then that party shall abandon such
well.


<PAGE>

25.      SURRENDER:

         (a) Either  party may at any time and from time to time  surrender  its
entire  interest  with respect to any portion or portions of the Lands by giving
to the other  party,  at least  sixty (60) days  before the date for  payment of
rentals  attributable  to those portions of the Lands proposed to be surrendered
or the  accrual  of any  obligation  thereon  other than the  obligation  to pay
royalties,  a written notice (hereinafter called the "surrender notice"),  which
shall be duly  executed  and  which  shall  specify  the  portions  of the Lands
proposed  to  be  surrendered   (which  portions  are  hereinafter   called  the
"surrendered rights"). It is specifically understood that the surrendered rights
shall be of a size and  dimension  which  the  other  party  hereto  can in turn
surrender should it wish to do so.

         (b) If the party to whom the surrender  notice is given fails to advise
the party giving the notice,  in writing,  within twenty (20) days after receipt
of the  surrender  notice,  that  it  elects  to join  in the  surrender  of the
surrendered  rights,  the party giving the surrender  notice shall convey to the
other party its entire interest in and to the surrendered rights, and the wells,
equipment and material located thereon and attributable  thereto,  and thereupon
the parties  hereto shall do all things and  complete and deliver all  documents
necessary to register the entire interest in the surrendered  rights in the name
of the  party  who  did  not  elect  to join in the  surrender,  and  upon  such
conveyance "the Lands" shall be deemed to be amended so as to exclude  therefrom
the surrendered  rights. If Panarctic is the surrendering party as to any Permit
or lease or portion thereof, Panarctic will in addition to its obligations above
insure at its expense that there are sufficient  allowable  expenditures,  cash,
rent or otherwise to maintain the  properties  in good standing for a period not
less  than  one year  from the date of  conveyance.  The  party  receiving  such
conveyance  shall  forthwith  pay to  Operator  for credit to the account of the
parties a sum equal to the fair salvage  value of all  recoverable  material and


<PAGE>

equipment  located  upon and  attributable  to the  surrendered  rights less the
estimated cost of salvaging,  such value to be determined in accordance with the
Accounting  Procedure.  Upon the execution and delivery of the conveyance by the
surrendering party, the surrendering party shall be released and discharged from
all obligations  thereafter accruing with respect to the surrendered rights, but
such conveyance shall not release the surrendering  party from its proportionate
share of any  obligation or liability  which ought to have been performed or may
have accrued prior to the conveyance of the  surrendered  rights.

26.      CHANGE OF OPERATOR:

         (a) An Operator  shall be discharged  forthwith and its powers,  rights
and duties as Operator shall be terminated if, subject to clause 42 hereof:

                  (i)      it  dissolves,  becomes  bankrupt,   liquidates  or
                           terminates its corporate existence, or

                  (ii)     it sells or  otherwise  disposes of a majority of its
                           interest  in the  Lands  other  than to an  affiliate
                           corporation, or

                  (iii)    having  defaulted in the  performance  of any term or
                           condition of this  Operating  Procedure,  it fails to
                           commence to remedy such default  within  fifteen (15)
                           days  after   receipt  of  written   notice   from  a
                           Non-Operator and thereafter to diligently  proceed to
                           remedy such default.

         (b) Subject to subclause (a) hereof,  an Operator may resign its duties
as such after  giving to  Non-Operator  six (6)  months'  written  notice of its
intention to resign.

         (c) At any time after an Operator  has acted in that  capacity  for two
(2) years,  Non-Operator  may, if dissatisfied with the manner in which Operator
is performing its  obligations  hereunder,  serve notice in writing on Operator,
advising Operator of such dissatisfaction and set forth the terms and conditions
under  which it is  prepared  to  operate  the  Lands,  and  which  will be more
efficient  and  beneficial  to the  parties  hereto;  or if the  dissatisfaction
results from uneconomical  operations,  then advising of the specific  economies
that it will effect as Operator.  Unless within sixty (60) days after receipt of


<PAGE>

such notice  Operator agrees in writing to operate the Lands subject to the same
terms and conditions and to effect the same specific  economies and in fact does
so, then  Operator  shall be  discharged  and the party serving the notice shall
become Operator.  If the party serving the notice becomes  Operator  pursuant to
this  subclause then it shall operate the Lands on the same terms and conditions
mentioned in the notice and with the specific economies  described therein;  and
it shall not charge nor be entitled to any costs or  reimbursement in respect of
amounts  spent by it on the  subject of the  specified  economies  except as set
forth in the said notice.  It is  understood  and agreed that the  provisions of
this  subclause  shall not be utilized by any party at intervals  more  frequent
than at least two (2) years from any previous utilization of same.

         (d)  If an  Operator  is  discharged,  the  other  party  shall  become
Operator.  If an Operator submits its resignation,  the other party shall become
Operator.

         (e) If at any time  neither of the parties is able or willing to act as
Operator  pursuant to the  foregoing,  then the parties,  on notice by either of
them,  shall meet together for the purpose of appointing  an  independent  third
party to operate the Lands.  In the event the parties cannot reach  agreement on
an independent third party, then the party holding a majority in interest in the
Permits shall appoint a third party to operate the Lands. Such third party shall
operate  the Lands on the terms and  subject to the  conditions  as set forth in
this Operating Procedure and on such further terms and conditions as may, in the
opinion of the parties or the party holding a majority interest, as the case may
be, be necessary for such operation.


<PAGE>

         (f) Should any Operator for any cause cease to be Operator,  its rights
and  interests  in the Lands shall be  unaffected  thereby  and it shall  become
Non-Operator  herein and shall be thenceforth  bound by the terms and provisions
hereof as Non-Operator.  Either party hereto becoming a successor Operator shall
thereupon succeed to all the duties, powers, obligations, rights and authorities
given to Operator herein with respect to all operations of every kind thereafter
conducted  on the  Lands.  In every  case of a change of  Operator,  the  proper
adjustments  in the  accounts  of  parties  shall be made as of the date of such
change in order that no party  shall  suffer any  penalty or loss as a result of
such change. The outgoing Operator shall surrender  possession of and deliver to
a party hereto  becoming new Operator the exclusive  possession of the operating
rights hereunder and all undistributed cash on hand, together with copies of all
pertinent  books of account and records of the operations and true copies of all
documents, agreements or other papers relating thereto.

27.      LEASE SELECTION:

         (a) The  parties  shall  consult at least  sixty (60) days prior to the
date upon which  Petroleum and Natural Gas Leases may be selected from the lands
and the parties agree that such lands shall remain in the Non-Lease stage for as
long a period as possible.  If the parties can agree on a Lease  selection  then
such Lease selection  shall be the Lease selection of the parties.  If, however,
the parties  cannot  agree as to the Leases to be selected to the full extent of
the fifty (50%) percent of the initial area allowed under the Canada Oil and Gas
Land  Regulations,  then  those  upon which  agreement  can be reached  shall be
selected  and the  balance up to the fifty  (50%)  percent  limitation  shall be
selected, with each party designating Sections in an order determined by lot for
the account of the parties.


<PAGE>

         (b) In the event of  disagreement  as to a Lease  selection,  then if a
party  does not wish to select  Leases to the full  fifty  (50%)  percent  areal
extent referred to under subclause (a) above,  those Leases upon which agreement
can be reached will be selected  and the party  wishing to select the balance up
to the fifty (50%) percent  limitation  may do so and such balance shall be held
by such  selecting  party for its sole  account and any lands  comprised in such
solely  selected  Leases  shall  be held by such  party  free  and  clear of any
obligations under this Agreement.

         (c)  Subclause  (a) and  (b)  shall  apply,  mutatis  mutandis,  to the
selection of the remaining fifty (50%) percent of Leases  permissible,  pursuant
to Section 58 of the Canada Oil and Gas Land  Regulations  in  conjunction  with
Canada Oil and Gas Land Order No. 1, as amended, or similar provisions from time
to time in force.

         (d) It is understood  that any lease  acquired  under this Clause 37 by
either or both of the parties shall be subject to the Hembdt overriding royalty.

28.      RESTRICTIONS ON INDEPENDENT DRILLING:

         Notwithstanding  anything to the contrary in this Operating  Procedure,
and in particular Clause 6 hereof, no party shall be entitled to drill a well on
the Lands pursuant to the provisions of Clause 6 if at that time a well is being
drilled on the Lands  either as a joint  operation of the parties or pursuant to
the independent drilling provisions of Clause 6 hereof.

29.      TERM OF AGREEMENT:

         Except as otherwise  herein  provided,  this Operating  Procedure shall
continue in full force and effect as long as any portion of the Lands is jointly
owned by the parties hereto or at that later date (joint  ownership  continuing)
all  documents of title (and all renewals and  extensions  thereof) to the Lands
have  terminated  and all wells on  jointly  owned  Lands  have been  plugged or
abandoned,  all equipment thereon and therein salvaged,  and final settlement of
accounts had between the parties hereto.


<PAGE>

30.      FORCE MAJEURE:

         The  obligations  of a  party  to this  Operating  Procedure  shall  be
suspended  and it shall not be liable  for  damages  during  the time and to the
extent  that  such  party is  prevented  from  complying  with  its  obligations
hereunder in whole or in part by strikes,  lockouts,  acts of God or the Queen's
enemies,  war, laws,  orders or regulations of governmental  bodies or agencies,
unavoidable  accidents,  delays in transportation,  inclement  weather,  adverse
terrain,  failure of communications,  inability to obtain necessary materials in
the open market, or any other cause, except lack of finances, whether similar or
dissimilar to those  specifically  enumerated,  beyond the reasonable control of
the party affected.

31.      RELATIONSHIP OF PARTIES:

         Except as otherwise in this  Operating  Procedure  provided,  where the
parties hereto incur a liability to any other person,  such liability  shall not
be joint or  several  but each  party  shall be  separately  liable to the other
person for a portion of the total  liability  calculated in accordance  with its
participating  interest.  It is not the purpose of this  Operating  Procedure to
create any partnership,  mining partnership or joint venture  relationship,  and
neither this Operating Procedure nor the operations hereunder shall be construed
or  considered  as  creating  any such  relationship.  Any  trust  or  fiduciary
relationship  which may be created by this Operating  Procedure shall be limited
only to matters  directly  related to those  operations upon the Lands which are
expressly provided for herein.


<PAGE>

32.      CONFORMANCE WITH LAWS:

         This Operating  Procedure and the respective  rights and obligations of
the  parties   hereunder  shall  be  subject  to  all  applicable  laws,  rules,
regulations  and  orders,  and in the  event  this  Operating  Procedure  or any
provision  hereof is, or the  operations  contemplated  hereby are,  found to be
inconsistent  with or contrary to any such law, rule,  regulation or order,  the
latter shall be deemed to control and this Operating Procedure shall be regarded
as modified  accordingly,  and as so modified  shall  continue in full force and
effect.

33.      CONFIDENTIAL INFORMATION:

         All data and  information of whatsoever  nature acquired by the parties
from any  operations  pursuant to this  Operating  Procedure  or supplied by one
party to the other  pursuant  hereto shall be for the sole and exclusive use and
benefit of the parties unless the parties agree in writing to the  dissemination
of such  information  or unless a party is required to give such  information to
any  recognized  association  within the  petroleum  industry,  of which it is a
member, that engages in the exchange of factual information relating to the type
of operations contemplated by this Operating Procedure.

         Notwithstanding the foregoing,  any party shall be at liberty,  without
the written consent of the other party, to release such data and information to

         (a)      an affiliate  corporation provided such affiliate  corporation
                  undertakes  in writing  with the other  party  hereto that the
                  affiliate corporation shall treat such data and information in
                  the strictest of confidence and shall not further disclose, or
                  permit to be disclosed, such data and information to any other
                  person, firm or corporation, or


<PAGE>

         (b)      to  any   nationally   recognized   lending   institution   or
                  underwriting  organization  for the  bona  fide  purpose  of a
                  proposed borrowing or sale of securities  PROVIDED ALWAYS that
                  any  subsequent  release  of data and  information  or studies
                  resulting  therefrom  shall be solely for the  purpose of such
                  lending or sale and shall be limited to the  minimum  required
                  for that purpose, or

         (c)      to any  governmental  authority  when  required  by law. In no
                  event  shall  information  relating  to  wells  drilled  on  a
                  confidential  basis to the  parties,  or  either  of them,  be
                  disclosed, or

         (d)      to  any  of the  parties  (and  their  assigns)  to a  certain
                  agreement  between  Panarctic  Oils Ltd.  and Tenneco Oils and
                  Minerals Ltd., Columbia Gas System, Inc., Northern Natural Gas
                  Company and Texas Eastern  Transmission  Corporation dated the
                  first  day  of  May,  1971  (hereinafter  referred  to as  the

         (e)      to J.  C.  Sproule  and  Eric  Connelly  (and  their  assigns)
                  pursuant to an Agreement  between Panarctic and the said J. C.

                  1st, 1967, or

         (f)      to a prospective purchaser of the interest of either party.

34.      FURTHER ASSURANCES:

         Each of the parties hereto  shall at all times do all such further acts
and  execute  and  deliver  all such  further  deeds and  documents  as shall be
reasonably  required  in order  fully to perform and carry out the terms of this
Operating Procedure.


<PAGE>

35.      OVERRIDING ROYALTIES:

         In the event  the  working  interest  of a party  hereto  is  presently
subject to other than the Hembdt royalty or may hereafter  become subject to any
overriding  royalty,  production  payment  or other  burden  and the same is not
charged to the joint  account of the parties,  such  royalty,  payment or burden
shall be borne  by the  party  creating  the  same or  against  whom the same is
enforced.  Provided  that if a party hereto shall  conduct any operation or make
any  election  as a result of which it becomes  entitled  to receive the working
interest  production  otherwise  belonging to the other party hereto,  the party
entitled to receive the working  interest  production  of the  non-participating
party shall receive such  production  free and clear of all royalties,  payments
and burdens (other than those charged to the joint account as aforesaid) against
such  production  which may have been  created  prior to or  subsequent  to this
Operating  Procedure and the party creating such royalties,  payments or burdens
shall  save the party  acquiring  such  interest  harmless  with  respect to the
receipt of such working interest production. The Hembdt royalty is to be charged
to the joint account.

36.      ENCUMBRANCES:

         Subject to the terms of this Operating  Procedure,  each of the parties
hereto  covenants  that it will not encumber or permit or cause to be encumbered
in any way the Lands or the Permits  without  the  written  consent of the other
party  hereto  being  first had and  obtained,  except  by means of  instruments
evidencing the bona fide loan of money to the encumbering  party,  and then only
if such instrument is restricted to the interest of the encumbering  party,  and
subject to the  provisions  of this  Operating  Procedure and all the rights and
interests of the other party hereto.


<PAGE>

37.      UNITED STATES TAX PROVISION:

         Notwithstanding  any provisions  herein that the rights and liabilities
of the parties  hereto are  separate  and not joint or  collective  or that this
Operating  Procedure  and  the  operations  hereunder  shall  not  constitute  a
partnership,  if for United States  Federal  Income Tax purposes this  Operating

38.      AREA OF COMMON INTEREST:

         Except as hereinafter in this Clause 38 expressly  provided,  if at any
time prior to  December  31st,  l984,  either  party shall  acquire  directly or
indirectly any interest of any nature or kind,  beneficial or otherwise,  in any
permits or leases of or pertaining to oil and/or gas, including mineral or other
substances produced in association with oil and/or gas, covering lands, any part
of which is  located in the area  outlined  in blue on the map  attached  hereto
marked Schedule "D" to the Farmout Agreement  (hereinafter called the "Acquiring
Party"),  it shall forthwith give notice in writing to the other party hereto of
such  acquisition to the extent only that such  acquisition  relates to the area
located  within  the blue  outline  on  Schedule  "D"  (hereinafter  called  the
"Acquired  Interest"),  specifying the description of the lands and documents of
title,  extent of interest and the  consideration  paid or payable and the terms
and conditions,  if any,  attached  thereto (if the  consideration is other than
cash  then  a cash  equivalent  shall  be  specified)  as  well  as any  factual
information  which is then being withheld under Clause 6(1). The party receiving
such  notice  shall have the right and  option for a period of twenty  (20) days
thereafter  within  which to elect  to  acquire  that  portion  of the  Acquired
Interest  which is  equivalent  to its  participating  interest  at such time by
paying to the Acquiring  Party a like proportion of the  consideration  (or cash
equivalent) paid for the Acquired  Interest and assumption of a similar share of
all  obligations  attached  thereto.  In the event that the party receiving such
notice  shall elect to acquire an interest in the  Acquired  Interest,  then the
lands covered by the Acquired  Interest shall thereafter be included in and form
part of the  Lands  and be  subject  to this  Operating  Procedure  and shall be
thereafter  owned and  operated by the  parties  hereto in  accordance  with and
subject to all applicable  terms and  conditions of this Operating  Procedure in
the  proportions  of their  respective  interests  therein.  Each of the parties
covenants  and agrees to execute and deliver all such  assignments,  conveyances
and other  documents as may be necessary to vest title to the Acquired  Interest
in the  parties to this  Operating  Procedure  but if the party  receiving  such
notice fails to exercise the  aforesaid  rights within the time  stipulated,  it
shall thereafter have no right or interest  whatsoever in the Acquired  Interest
or the lands covered thereby.

         The provisions of this Clause shall not apply to

         (a)      any acreage located in the half grid corridors surrounding the
                  Permits  which is subject  to a now  existing  after  acquired
                  provision between Farmee and third parties, or the Farmor, or

         (b)      interests  acquired by either  party in any lands by virtue of
                  the  selection of leases  pursuant to the  provisions  of this
                  Operating Procedure, or

         (c)      interests  acquired in any lands by virtue of an assignment to
                  either  party  pursuant  to the  provisions  of  Clause  24 or
                  subclause II of Clause 6, or which are surrendered or assigned
                  pursuant to the provisions of Clause 25.

39.      ALIENATION:

         (a) Either party may dispose of any interest  hereunder,  provided that
no such  disposition  hereinabove  referred to shall be effective to increase or
multiply the obligations of the other party, whether as Operator or Non-Operator
under this Operating  Procedure,  and any disposition made as aforesaid shall be
subject to this express provision,  and the disposing party and such third party
shall enter into, execute and deliver any documents  necessary to give effect to
this  provision  and assume all the  obligations  attributable  to the  interest
affected.  The  remaining  party hereto shall not be bound to take notice of any
such  disposition  until such  documents are executed end delivered to it by the
disposing party.

         (b) Subject to the foregoing, this Operating Procedure shall be binding
upon and  enure to the  benefit  of the  parties  hereto  and  their  respective
successors and assigns.

40.      PARTITION:

         Each  party to this  Operating  Procedure  covenants  by its  execution

THIS IS EXHIBIT "A" to an Operating Procedure  entered  into  between  PANARCTIC
OILS LTD. and CANADA SOUTHERN PETROLEUM LTD.





                              ACCOUNTING PROCEDURE


                              I. GENERAL PROVISIONS

1.       Definitions

         "Joint  property"  shall mean the  properties  subject to the Operating
         Procedure to which this "Accounting Procedure" is attached.

         "Material" shall include equipment and supplies.

         "Operator"  shall  mean  the  Operator  as  defined  in  the  Operating
         Procedure to which this "Accounting Procedure" is attached.

         "Non-Operator"  shall  mean  any  one  or  more of the  parties  to the
         Operating Procedure who are not the Operator.

2.       Statements and Billings

         The Operator shall bill  Non-Operator  either on or before the last day
         of each month for its share of charges and credits during the preceding
         month. Such bills will be accompanied by statements, as follows:

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

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

         (3)      Detailed statement of any other charges and credits.

3.       Payments by Non-Operator

         Each  Non-Operator  shall pay all such bills  within  fifteen (15) days
         after  receipt  thereof.  If payment is not made within such time,  the
         unpaid  balance  may, at the  Operator's  option,  and without  further
         notice  to the  Non-Operator,  bear  interest  at the  rate of six (6%)
         percent per annum until paid.


<PAGE>

4.       Advances

         Unless otherwise provided for in the Operating Procedure,  the Operator
         may require the  Non-Operator  to advance its share of  estimated  cash
         outlay for the current month's operation.

5.       Adjustments

         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 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  Non-Operator  takes  written  exception
         thereto and makes claim on Operator for adjustment. Failure on the part
         of  Non-Operator  to make claim on Operator for adjustment  within such
         period shall establish the correctness  thereof and preclude the filing
         of exceptions thereto or making of claims for adjustment thereon.

         The  provisions  of  this  paragraph  shall  not  prevent   adjustments
         resulting  from  physical  inventory  of  materials  as provided for in
         Section VI, Inventories, hereof.

6.       Audits

         A  Non-Operator,  upon  notice in  writing  to  Operator  and all other

         audit  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
         Non-Operator  must take  written  exception  to and make claim upon the
         Operator  for all  discrepancies  disclosed  by said audit  within 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.

                  suitable for reconditioning,

         at 50% of current new price.

4.       Bad Order Material

         Bad order material  (Condition  "D"), being material not further usable
         for its original  function but for possible other  service,  at a value

                                 VI. INVENTORIES

1.       Periodic Inventories

         Periodic  inventories  of  material  which  is  ordinarily   considered
         controllable shall be taken by Operator at reasonable  intervals but at
         least once in every five years.

2.       Notice

         Notice of  intention  to take  inventory  shall be given by Operator at
         least  thirty  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.

4.       Reconciliation of Inventory

         Reconciliation  of inventory with charges to the joint account shall be
         made by each party at interest,  and a list of overages  and  shortages
         shall be jointly determined by said parties.

5.       Adjustment of Inventory

         Inventory  adjustments  shall be made by Operator to the joint  account
         for overages and shortages,  but Operator shall be held  accountable to
         Non-Operator only for shortages due to lack of reasonable diligence.

6.       Inventory Expenses

         The expense of more than one  representative of the Operator,  and more
         than one representative for all of the Non-Operators  jointly,  present
         at the taking of regular  inventory,  shall not be charged to the joint
         account.

7.       Special Inventories

         Non-Operator shall have the right at any time to request in writing the
         taking of a special  inventory.  The taking of such  special  inventory
         shall be commenced  within thirty (30) days after the receipt of notice
         thereof.  All expenses  incurred by Operator in conducting  any special
         inventory so requested shall be charged to the separate  account of the
         requesting party.

                     VII. REVISIONS TO ACCOUNTING PROCEDURE

         The parties to the Operating  Procedure  acknowledge and agree that the
         purpose of this Accounting  Procedure is to establish equitable methods
         for determining  charges and credits applicable to operations under the
         Operating Procedure,  it being the parties' intention that the Operator
         as such, should not profit by or suffer any losses by its operations as
         Operator;   the  parties  also  recognize  that  operations   north  of
         70(degree)  Latitude  differ  substantially  from  operations  in  more
         southerly  locations and that at the date of  negotiation  of the terms
         and  provisions of this  Accounting  Procedure  there is  comparatively
         little knowledge or experience in the conduct of operations in the area
         in which the joint property is located.  Accordingly the parties to the
         Operating  Procedure agree that  notwithstanding the provisions of that
         Clause of the Operating  Procedure entitled "Change of Operator" (which
         Clause  shall  remain in full  force and  effect but shall not be or be
         deemed to be a limitation  or  restriction  on the  provisions  of this
         Section VII), this Accounting  Procedure shall be subject to review and
         possible revision from time to time but only in the manner  hereinafter
         provided for.

         If in practice the charges,  rates,  and/or other terms and  provisions
         (whether similar or dissimilar) of this Accounting  Procedure are found
         to be  insufficient  or excessive  then any party hereto may serve upon
         the other  parties  hereto,  at any time during the  calendar  month of
         January in any  calendar  year,  a notice  setting  forth the  specific
         revisions to the Accounting  Procedure  requested by it,  whereupon the
         parties shall meet together,  at the instigation of any of them, during
         the following  calendar month of February and in good faith endeavor to
         agree  on  such   revisions   as  may  be   necessary  to  remedy  such
         insufficiency  or excess and to establish  the  effective  date of such
         revisions, which effective date may be retroactive.

         In the  event  the  parties  cannot  reach  agreement  within  the said
         calendar  month of February  then  Operator  shall during the following
         calendar  month of March  serve upon the other  parties  notice of such
         specific  revisions  to  this  Accounting  Procedure,  together  with a
         suggested effective date of such revisions (which effective date may be
         retroactive  to a date not earlier  than  January 1st of the  preceding
         calendar  year) which it is prepared to accept,  or in the  alternative
         that it does not desire any revisions,  and,  unless one or more of the
         other parties  serves a notice of objection on all other parties within
         fifteen  (15) days of  receipt of the notice  from the  Operator,  this
         Accounting  Procedure  shall  be and be  deemed  to be  revised  or not
         revised,  as the case may be, in accordance with the Operator's notice,
         and any  revisions  shall be effective on that date so specified in the
         Operator's  notice.  In the  event a  Non-Operator  files a  notice  of
         objection as to either the specific revisions or the effective date, or
         both, the matter shall be submitted to  arbitration in accordance  with
         the  provisions of the  Arbitration  Act of the Province of Alberta (in
         the event the parties  cannot reach  agreement on a single  arbitrator,
         each shall appoint an  arbitrator  and those  arbitrators  so appointed
         shall appoint a third) for the purpose of reaching a decision as to the
         most equitable revision,  if any, required to this Accounting Procedure
         and to establish  the most  equitable  effective  date  thereof  (which
         effective  date may be  retroactive  to a date not earlier than January
         1st of the preceding  calendar  year)  provided  always that only those
         items or matters specifically  contained in the notices of the parties,
         including the Operator,  served in accordance with all of the foregoing
         provisions   of  this  Section  VII,   shall  be   considered  in  such
         arbitration.


<PAGE>

         Any revisions made to this Accounting  Procedure shall continue in full
         force and effect and be applicable  as, of and from the effective  date
         thereof  as  established  in  accordance  with the  foregoing  and this
         Accounting Procedure shall be and be deemed to be amended accordingly.

expenses  incurred by it on or with  respect to such Block  after the  effective
date of this Carried Interest  Procedure,  including without limitation drilling

         (b)      the monthly operating costs exceed  the monthly gross proceeds
                  of production,


<PAGE>

it shall be entitled to recover the amount  thereof out of the gross proceeds of
production  from such Block  before  commencing  to make  payments  again to the
Carried Interest Owner as aforesaid, and so on from time to time.

5.       APPLICATION OF OPERATING PROCEDURE:

         Subject to the specific  provisions of this Carried Interest Procedure,
all of the provisions of the Operating  Procedure  shall apply mutatis  mutandis
between the parties hereto and be deemed to be incorporated herein except to the
extent that any such terms and  conditions  are  inconsistent  with the specific
provisions and intent of this Carried Interest  Procedure and generally accepted
understandings  in the  industry  of a net  carried  interest,  and the  Carried
Interest Owner shall have the same rights as a Non-Operator  and Panarctic shall
have the same rights as the Operator  under such  applicable  provisions  of the
Operating Procedure. In particular,  but not so as to restrict the generality or

                  otherwise, or to the expenditure of monies thereon;

         (b)      Panarctic  agrees to advance or obtain the  advancement of all
                  monies for the  conduct of  operations  on the said Lands such
                  that no monies need be advanced by the Carried Interest Owner;

         (c)      the Carried Interest Owner's entire interest in the operations
                  conducted  on the said Lands,  while  subject to this  Carried
                  Interest Procedure,  the equipment pertaining thereto, and the
                  petroleum   substances   produced   therefrom   shall  be  the
                  percentage  of the net  carried  interest  in net  proceeds of
                  production  of  petroleum  substances   produced,   saved  and
                  marketed as provided for above;

                  acquired,  the  provisions  of the Operating  Procedure  shall
                  apply thereto;

         (e)      the  Carried  Interest  Owner  shall have no rights  under the
                  provisions of the Clause of the Operating  Procedure  entitled
                  "Independent Drilling and Deepening".

6.       EFFECTIVE DATE:

         The  effective  date of this Carried  Interest  Procedure  shall be the

Procedure.

9.       ENUREMENT:

         This  agreement  shall enure to the benefit of and be binding  upon the
parties hereto and their respective heirs, executors, administrators, successors
and assigns.

         Agreement 1-1-75

         Canada  Southern  and/or its assigns  shall have the right from time to

         W.I.  position in two stages with no interest so  converted  to be less
         than 1/6th of the 30% C.I. The following  procedure shall apply to such
         conversion mutatis mutandis.

10.      CONVERSION TO WORKING INTEREST:

         (a)      At any time  when  Panarctic  has  recovered  from  the  gross
                  proceeds of production  from any Block  all costs and expenses
                  made by it on such Block, as hereinbefore provided in clause 4
                  (or at any date prior thereto if the  Carried  Interest  Owner
                  pays to Panarctic an amount equal to thirty 30% percent of all
                  such costs and expenses  incurred to that date by Panarctic on
                  such Block and which have not been recovered  by  Panarctic as

                  Thirty (30%) percent  working  interest.  Such election may be
                  made by notice in writing served upon  Panarctic in the manner
                  provided in the Operating Procedure.


<PAGE>

                  Thereafter all the provisions of the Operating Procedure shall
                  apply and the participating  interests of the parties shall be
                  adjusted  accordingly  and  the  provisions  of  this  Carried
                  Interest  Procedure shall no longer apply with respect to such
                  Block.  After converting its net carried interest to a working
                  interest, as in this clause 10 provided,  the Carried Interest
                  Owner  shall  have no  further  right  of  conversion  and its
                  interest shall remain as a working interest.

         (b)      [Replaced  by new clause  giving  C.S.  right to sell & commit

"Company"), and its subsidiaries or affiliates, by making available stock of the
Company  for  purchase  by  eligible  directors,  officers,  key  employees  and
consultants  of the  Company and its  subsidiaries  or  affiliates,  and thus to
provide an additional  incentive to such persons to continue  their  affiliation
with the Company and its  subsidiaries  or affiliates and to give them a greater
interest as stockholders in the success of the Company.

         2.  Stock Subject to Plan.  There shall  be  reserved  for  issuance or
transfer  upon the exercise of options to be granted from time to time under the
Plan an aggregate of 600,000  shares of the  Company's  Limited  Voting  Shares,
$1.00 par value (the  "Shares"),  which shares,  as the Board of Directors shall
from time to time determine,  may be in whole or in part authorized and unissued
shares of stock or issued  shares of stock which shall have been  reacquired  by
the Company.  If any option granted under the Plan shall expire or terminate for
any reason without having been exercised in full, the unpurchased shares subject
thereto shall again be available for the purposes of the Plan.

         3.  Administration. The Board of Director of the Company shall act as a
committee of the whole (the "Committee") to administer the Plan. No director who
is at that time  eligible to receive an option under the Plan shall  participate
as a member of the Committee in the granting of an option to such director.

         The Committee  shall have  absolute  authority in its  discretion,  but
subject to the express  provisions  of the Plan,  to determine  (i) the purchase
price of the Shares  covered by each  option,  (ii) the persons to whom  options
shall be  granted,  (iii) the time or times at which  options  shall be granted,
(iv) the  number of shares to be  subject  to each  option,  and (v) the time or
times at which an option can be exercised and whether in whole or  installments;
to interpret  the Plan; to  prescribe,  amend and rescind rules and  regulations
relating to the Plan;  to determine  the terms and  provisions  (and  amendments
thereof) of the  respective  option  agreements  (which need not be  identical),
including such terms and provisions (and amendments) as shall be required in the
judgment  of the  Committee  to conform  to any change in any law or  regulation
applicable  thereto;  and to  make  any  and  all  other  determinations  deemed
necessary or  advisable  for the  administration  of the Plan.  The  Committee's
determination on the foregoing matters shall be conclusive.

         The Committee shall select one of its members as its chairman and shall
hold its  meetings at such times and places as it may  determine.  A majority of
the members shall constitute a quorum,  and all  determinations of the Committee
shall be made by not less than a majority of its members.  The  Committee  shall
establish such rules and regulations for the conduct of its business as it shall
deem advisable.

         4.  Eligibility.  Options  under  the  Plan  may  be  granted  only  to
directors,  officers,  key employees and  consultants  of (i) the Company,  (ii)
subsidiary  corporations of the Company from time to time  ("Subsidiaries")  and
(iii) any  business  entity in which the Company  shall from time to time have a
substantial interest  ("Affiliate").  In determining the persons to whom options
shall be granted  and the number of shares to be  covered  by each  option,  the
Committee  may take into  account  the nature of the  services  rendered by such
persons,  their present and potential contribution to the Company's success, and
such other factors as the Committee in its discretion shall deem relevant.

         5.  Option  Prices.  The  purchase  price of Shares  under each  option
shall be determined by the  Committee.  The purchase price may be less than fair
market value of the Shares at the time of granting, but may not be less than the
greater of (i) the par value  thereof and (ii) the fair value of the shares less
any discount permitted by The Toronto Stock Exchange.

         6.  Exercise  of  Option.  Unless  otherwise  provided  in  the  option
agreement,  an  option  granted  under  the Plan  shall  become  exercisable  in
installments  as  follows:  to the extent of  twenty-five  (25%)  percent of the
number  of  shares  originally  covered  thereby,  in  the  calendar  year  next
succeeding  the date of grant of the option,  and to the extent of an additional
twenty-five  (25%)  percent  of such  number  of  shares  in  each of the  three
succeeding  years  thereafter.   Such  installments  shall  be  cumulative.  The
Committee  shall have  authority  in its  discretion  to prescribe in any option
agreement that the option may be exercised in different  installments during the
term of the option.  In any event,  options granted to individuals who have been
associated  with the  Company  for not less than ten  years  may be  exercisable
immediately.  The purchase  price of the shares to be acquired  shall be paid in
full upon the exercise of the option,  and the Company  shall not be required to
deliver  certificates for such shares until such payment has been made. The term
of each option shall be for such period as the Committee  shall  determine,  but
not more than ten  years  from the date of  granting  thereof,  or such  shorter
period as described in  Paragraphs 8 and 9 hereof.  As to  employees,  except as
provided in Paragraphs 8 and 9, an option  granted to an employee of the Company
or one of its Subsidiaries or Affiliates, may not be exercised unless the holder
thereof is at the time of such  exercise (and has been since the date or grant),
an  employee or a retiree of the  Company or one of its then  Subsidiaries  or a
then  Affiliate.  The holder of an option  shall not have any of the rights of a
stockholder with respect to the shares subject to option until such shares shall
be issued or transferred to him upon exercise of his option.

         7.  Limited Transferability of Options.  No options  granted under  the
Plan shall be  transferable,  except that options may be  transferred  to and be
exercised by members of an optionee's  immediate family, and each option granted
pursuant to the Plan may be  exercised  during an  optionholder's  lifetime,  or
pursuant to Paragraph 9 hereof.

         8. Termination of Employment. In the event of termination of employment
of an employee to whom an option has been granted under the Plan, other than (a)
a termination  that is either (i) for cause or (ii) voluntary on the part of the
employee and without the written consent of the Company, or (b) a termination by
reason of death,  the  employee  may  (unless  otherwise  provided in his option
agreement)  exercise  his  option at any time  within  three  months  after such
termination of employment,  or such other time as the Committee shall authorize,
but in no event after ten years from the date of granting thereof, to the extent
of the number of shares  covered by his option which were  purchasable by him at
the date of termination of his  employment.  In the event of the  termination of
the  employment of an employee to whom an option has been granted under the Plan
that is  either  (i) for  cause or (ii)  voluntary  on the part of the  employee
without the written  consent of the  Company,  any options held by him under the
Plan,  to the extent  not  theretofore  exercised,  shall  forthwith  terminate.
Nothing in the Plan or any option  granted  pursuant to the Plan shall confer on
any individual any right to continue in any capacity his  relationship  with the
Company or any of its  Subsidiaries  or  Affiliates or interfere in any way with
the right of the Company or any of its  Subsidiaries  or Affiliates to terminate
such relationship at any time.

         This Paragraph 8 is applicable  only to options  granted to and held by
full time  officers and employees  and is not  applicable to options  granted to
directors, retirees of the Company and consultants.

         9.  Death of Holder of Option.  In the event of the death of any holder
of an  option  which  has been  granted  under the  Plan,  such  option  (unless
previously  terminated)  may be exercised (to the extent of the number of shares
covered by such option which were  purchasable by such person at the date of his
death) by a legatee or legatees of such option under such  person's  will, or by
such person's  personal  representative  or  distributees,  at any time within a
period of one year  after his  death,  but not after ten years  from the date of
granting thereof.

         10.  Retirement of Holder of Option.  In the event of the retirement of
a holder of an option which has been granted under the Plan, such option (unless
previously  terminated)  shall  continue to be  exercisable  in accordance  with
Paragraph  6 hereof but no more than ten years from the date of granting or such
shorter period as described in paragraph 9 hereof.

         11.  Adjustment Upon  Changes in  Capitalization.  Notwithstanding  any
other  provisions of the Plan, each option agreement may contain such provisions
as the Committee  shall  determine to be  appropriate  for the adjustment of the
number and class of shares subject to such option and of the option price in the
event of changes  in the  outstanding  Stock by  reasons of any stock  dividend,
split-up,   recapitalization,   combination  or  exchange  of  shares,   merger,
consolidation,  acquisition of property or stock, separation,  reorganization or
liquidation  and  the  like,  and,  in the  event  of  any  such  change  in the
outstanding  Stock, the aggregate number and class of shares available under the
Plan shall be appropriately  adjusted by the Committee,  whose  determination of
such adjustment shall be conclusive.

         12.  Amendment and  Termination.  The Board of Directors of the Company
may terminate the Plan or make such  modifications  or amendments  thereof as it
shall  deem  advisable,  or in  order to  conform  to any  change  in any law or
regulation  applicable  thereto.  Without  the consent of any person to whom any
option shall  therefore  have been  granted,  no  termination,  modification  or
amendment of the Plan shall  adversely  affect any rights  which may  previously
have been granted under the Plan to such person.

         13.  Effectiveness of Plan.  The  Plan  shall  be  effective  upon  its
approval by the shareholders of the Company.

specified the working interests and carried interests to be held by the parties.
The l959  Agreement  contained a detailed  Operating  Procedure  and  Accounting
Procedure.  The April 1, 1966  agreement  added a schedu1e  of Carried  Interest
Provisions to the 1959 Agreement.

10. On or about  February 1, 1977,  Canada  Southern  together with Dome,  Amoco
Canada and the  predecessor  of Mobil,  entered  into a written  agreement  with
Columbia.  Canada Southern  agreed to reduce its 50% carried  interest in and to
the  Kotanelee  field  to a 33 1/3%  carried  interest  and  assigned  a 16 2/3%
interest to Co1umbia. Columbia undertook to drill a test well under the terms of
the agreement and to act as the operator of the lands.


<PAGE>

11. As to Canada  Southern's  carried interest,  the agreements  provided that a
portion of certain  expenditures  made for the joint  account  would be deducted
from  revenues  from  production  before  any  payments  would be made to Canada
Southern by the Defendants.  Columbia has reported that the expenditures for the
joint account, for exploration and development costs,  including gathering lines
and  dehydration  equipment,  amount to over  $61,000,000,  which  amount is not
admitted by Canada Southern.

12. In early 1987, Columbia, as managing operator,  advised Canada Southern, for
the first time,  that interest  would accrue on all  expenditures  for the joint
account and would be charged against Canada Southern's  carried interest.  There
is no provision in the agreements expressly allowing interest to accrue upon the
expenditures  for the joint account and no interest was shown  previously on any
statements of operations provided to Canada Southern.

13. Essentially,  Columbia,  and the other Defendants,  are contending that they
are entitled to receive  interest upon their  investment in the Kotanelee  lands
before Canada Southern will receive any revenue from gas produced.

14.  Canada  Southern  denies  that the working  interest  owners may accrue and
charge  interest  on  expenditures  for the joint  account  and states  that any
attempt to charge  interest is contrary to the terms of the agreements  relating
to the Kotanelee field.

15. Further,  Canada Southern stated that the  expenditures  for gathering lines
and  dehydration  equipment  are,  as has always  been  reported  in the past by
Columbia, expenditures made for the joint account,  notwithstanding any contrary
position that may be taken by certain of the Defendants.

16. This actual  controversy  and dispute  will have a dramatic  effect upon the
expected  revenues to be received by Canada  Southern from  production  from the
Kotanelee field.

         WHEREFORE the Plaintiff Canada Southern Petroleum Ltd.  claims  against
the Defendants and each of them:

         (a)      A declaration  that interest  cannot accrue or be charged upon
                  expenditures for the joint account made by the Defendants;


<PAGE>

         (b)      A  declaration  that  expenditures  for  gathering  lines  and
                  dehydration equipment are expenditures for the joint account;

         (c)      Costs of this action; and

         (d)      Such  further and other  relief as this  Honourable  Court may
                  deem fit.

                           AMENDED STATEMENT OF CLAIM



1. The Plaintiff,  Canada Southern  Petroleum Ltd.  (hereinafter  referred to as
"Canada  Southern") is a body  corporate,  incorporated  pursuant to the laws of
Nova Scotia (formerly under the laws of Canada), registered to carry on business
in the  Province  of Alberta,  with head  office in the City of Calgary,  in the
Province of Alberta.

2. The Defendant,  Amoco Production Company,  (hereinafter referred to as "Amoco
Production") is a body corporate  incorporated pursuant to the laws of the State
of Delaware, of the United States of America, registered to carry on business in
the Province of Alberta.

3. The Defendant,  Amoco Canada Petroleum Company Ltd.  (hereinafter referred to
as "Amoco  Canada")  is a body  corporate  incorporated  pursuant to the laws of
Canada,  registered  to carry on business in the Province of Alberta,  with head
office located in the City of Calgary, in the Province of Alberta.  Amoco Canada
is the assignee and successor in interest to Amoco Production.


<PAGE>

4. The Defendant,  Dome Petroleum Limited (hereinafter referred to as "Dome") is
a body  corporate  incorporated  pursuant to the laws of Canada,  registered  to
carry on business in the  Province of Alberta,  with head office  located in the
City of Calgary,  in the Province of Alberta.  On May 1, 1989,  Dome and another
corporation  amalgamated,  pursuant to the laws of Canada, to form the Defendant
Amoco Canada Resources Ltd. (hereinafter referred to as "Amoco Resources").

5. The Defendant,  Columbia Gas Development of Canada Ltd. (hereinafter referred
to as  "Columbia")  is a body  corporate  incorporated  pursuant  to the laws of
Canada,  registered  to carry on business in the Province of Alberta,  with head
office located in the City of Calgary, in the Province of Alberta.

6. The Defendant,  Mobil Oil Canada Ltd. (hereinafter referred to as "Mobil") is
a body  corporate  incorporated  pursuant to the laws of Canada,  registered  to
carry on business in the  Province of Alberta,  with head office  located in the
City of Calgary, in the Province of Alberta.

7. The Defendant,  Esso Resources  Canada  Limited  (hereinafter  referred to as
"Esso")  is a body  corporate  incorporated  pursuant  to the  laws  of  Canada,
registered  to carry on  business in the  Province of Alberta,  with head office
located in the City of Calgary, in the Province of Alberta.

8.  Amoco  Canada,  Columbia,  Esso,  Mobil and Amoco  Resources  are  currently
interest  owners in the nature of a working  interest in properties now known as
the Kotaneelee area located in the Yukon Territory  (hereinafter  referred to as
the "current working interest owners").  Columbia has been the managing operator
of the Kotaneelee lands since on or about February 1, 1977.

9. Canada Southern was formerly the only working interest owner and is currently
in the nature of a 33 1/3% carried  interest  owner, on behalf of itself and two
other parties, in these same properties in the Kotaneelee area.

10. The  Kotaneelee  lands were  acquired and held by Canada  Southern  prior to
1959,  as part of oil  and  gas  permits  granted  in the  Yukon  and  Northwest
Territories.  Canada Southern  conducted  exploration  upon the Kotaneelee lands
prior to any involvement of the Defendants.


<PAGE>

11. In 1959,  pursuant to an oil and gas exploration,  development and marketing
contract dated as of May 28, 1959 (the "1959 Agreement"), Canada Southern agreed
to transfer a 50%  interest in the oil and gas  permits to the  predecessors  or
assignors  of  Amoco  Canada,  Dome  and  Mobil.  One  of  the  express  recited
considerations  for the transfer of this 50%  interest was that the  transferees
would,  pursuant  to  Article  III 3.1 (D) "...  assure  the  earliest  feasible
development and marketing of oil and/or gas found on the properties."

12. This express  consideration was a fundamental term of the 1959 Agreement and
Canada Southern relied upon the assurance that the properties would be developed
and gas sold at the earliest feasible opportunity.

13. Amoco  Production and Dome expressly agreed to be bound by all the terms and
provisions  of the  1959  Agreement,  when  they  acquired  their  interests  by
assignment,  in the Kotaneelee  lands, in the period from 1959 to 1966, and they
were expressly bound to assure such earliest feasible  development and marketing
of Kotaneelee oil and/or gas, for the benefit of Canada  Southern.  Amoco Canada
as the assignee and  successor in interest to Amoco  Production  is bound by all
the terms and provisions of the 1959 Agreement.  Amoco Resources as the assignee
and  successor in interest to Dome is bound by all the terms and  provisions  of
the 1959 Agreement.

14. Mobil is the  successor  in interest to one of the  original  parties to the
1959  Agreement  and is bound by such  party's  assurance  to develop and market
Kotaneelee gas at the earliest feasible time.

15. The 1959  Agreement was modified,  by an agreement in writing dated April 1,
1966,  in which  Canada  Southern's  50%  interest in the  Kotaneelee  lands was
converted to a 50% interest in the nature of a carried interest.  From that date
to the  present,  Canada  Southern  has had no  rights in the  operation  of the
properties,  save and except for a vote on which of the current working interest
owners  would be manager  operator,  if the  existing  operator  resigned or was
replaced,  and certain other options.  In all other  respects,  Canada  Southern
relied  upon  the  working   interest  owners  who  exercised  their  discretion
concerning operations.


<PAGE>

16.  Columbia  acquired an  interest in the nature of a working  interest in the
Kotaneelee lands pursuant to an agreement in writing dated February 1, 1977 (the
"1977 Agreement").  Columbia agreed to drill a test well on the Kotaneelee lands
and to act as managing  operator of those lands and it further agreed to conduct
all  operations  in  accordance  with  the  terms  and  provisions  of the  1959
Agreement,  as modified.  In turn,  Canada  Southern  again agreed to reduce its
interest in the Kotaneelee lands to an interest in the nature of 33 1/3% carried
interest.

17. Columbia, either expressly or impliedly, agreed with Canada Southern that it
would be bound by the obligation to assure the earliest feasible development and
marketing of oil or gas from the Kotaneelee field.

18.  Esso  acquired  an  interest  in the  nature of a working  interest  in the
Kotaneelee  lands from Columbia in 1977. Since that date, it has taken an active
role in  discussions  and decisions  relating to the operation of the Kotaneelee
field and it is bound,  expressly or impliedly,  by all the terms and provisions
of the 1959 Agreement which remain in effect.

19. Canada Southern states that the effect of the 1959, 1966 and 1977 Agreements
is that the exploration,  development and production of the Kotaneelee lands was
to be a joint venture between Canada  Southern and the current working  interest
owners, for the benefit of all parties. As such, Canada Southern states that the
current  working  interest  owners owe a fiduciary duty to Canada  Southern with
respect to any dealings with the Kotaneelee field.

20. Further,  the current working interest owners, by undertaking to produce and
sell  gas at  the  earliest  feasible  time,  and by  agreeing  to  operate  the
Kotaneelee lands, became the agents of Canada Southern to sell or market any gas
found in the Kotaneelee  field. As agents,  the current working  interest owners
owe Canada  Southern a fiduciary  duty,  requiring that they act with the utmost
good faith.

21.  Further,  Canada  Southern  placed its trust and  confidence in the current
working interest owners and relied upon them to produce and market the gas found
in the Kotaneelee field.  Canada Southern was informed by the managing operator,
and other  Defendants,  of efforts to market the gas  discovered and relied upon
these  reports.  As a result of those  dealings,  the current  working  interest
owners owe a fiduciary duty to Canada Southern.


<PAGE>

22. In the  period  from  1977 to 1980,  three gas  wells  were  drilled  in the
Kotaneelee  field and it was known that there were extensive proven and probable
reserves  of  gas  in  the  structure  underlying  the  lands.  By  1980,  a gas
dehydration  system had been  constructed on the lands and the Kotaneelee  field
had been  tied  into the  Westcoast  Transmission  raw gas  pipeline,  which ran
through the field.

23. Since 1980, the current  working  interest  owners have not marketed or sold
any gas from the Kotaneelee  field,  except to test the gas dehydration  system,
notwithstanding that the field has been ready and able to produce.

24. In November, 1986, Canada Southern, without any prior knowledge, was advised
by Columbia  that a current  working  interest  owner had  declined a market for
Kotaneelee gas, earlier in 1986, as to which Canada Southern had no knowledge.

25. In 1988, Canada Southern,  without any prior knowledge,  discovered that the
operator of the field,  Columbia,  had thereafter refused, in 1986, to undertake
any further efforts to market Kotaneelee gas, after the market had been declined
earlier in 1986.

26. At the  present  time,  gas from the  Kotaneelee  field is not  being  sold,
notwithstanding  that  the  gas  fields  directly  to the  north  and  south  of
Kotaneelee have been produced and marketed to near depletion and notwithstanding
that the current working interest owners have, since 1980, produced and marketed
gas from  other  fields  in which  they hold an  interest.  The gas field to the
immediate  south of the  Kotaneelee  field has recently been reopened and gas is
apparently being marketed from that field.

27.  Canada  Southern  states  that the  current  working  interest  owners have
breached their fiduciary duty, have breached the express agreement to assure the
earliest  feasible  marketing of gas from the Kotaneelee lands and have breached
their obligation to act as prudent operators, by:

         (a)      refusing or failing to sell gas from the Kotaneelee field;

         (b)      declining the market for gas in 1986;


<PAGE>

         (c)      refusing or  declining  other  potential  markets for gas, the
                  particulars  of which will be  provided  prior to the trial of
                  this action;

         (d)      refusing to undertake any  further efforts to market gas after
                  1986;

         (e)      failing  to  make  full  and  complete  disclosure  to  Canada
                  Southern;

         (f)      producing and marketing gas from fields other than Kotaneelee,
                  in direct conflict with the duty owed to Canada Southern;

         (g)      failing  to act  in good faith  or in  the best  interests  of
                  Canada Southern in dealings with the Kotaneelee lands.

28. By reason of the matters  aforesaid,  Canada  Southern has suffered loss and
damage,  equal to Canada  Southern's  interest in the proceeds from sales of gas
which should have been realized and has been deprived of all economic benefit in
the Kotaneelee lands.

29. By reason of the matters aforesaid,  Canada Southern states that the actions
and  decisions  of the current  working  interest  owners  constitute a complete
repudiation  of the joint  venture to produce  and sell gas from the  Kotaneelee
field and are in disregard of the fiduciary duty owed to Canada Southern.

30. Further, as to Canada Southern's interest,  the 1959 Agreement,  as amended,
provided that a portion of certain expenditures made for the joint account would
be deducted from revenues  from  production  before any revenue would be paid to
Canada  Southern.  Columbia has  reported  that the  expenditures  for the joint
account  for  exploration  and  development  costs,  including  gas  dehydration
equipment, amount to over $61 million.

31.  Canada  Southern  disputes  and takes  exception  to the  amount  stated by
Columbia and claims an adjustment to the joint account, the particulars of which
shall be provided prior to the trial of this action.

32. Canada Southern  proposes that the trial of this action be held at the Court
House, in the City of Calgary, in the Province of Alberta.

         WHEREFORE the Plaintiff Canada Southern claims against the Defendants:

         (a)      an order  vesting  the  interests  of the  Defendants,  in the

                  Defendants in the Kotaneelee lands shall be forfeited;

                  Kotaneelee lands between Canada Southern and the Defendants;

                  may be taken, made or given;

4.  Additionally,  the  Defendants,  Amoco  Canada  and  Amoco  Resources,  seek
indemnification from the Third Party,  Anderson, for the claim of the Plaintiffs
on the following bases:

         (a)      (i)      On February 1, 1977 Anderson,  in accordance with the
                           terms of  the Columbia Farmout,  undertook  to  Amoco
                           Resources and Amoco Canada to indemnify and hold each
                           of them harmless from and against any and all claims,
                           demands,  suits or actions  arising out of Columbia's
                           operation thereunder.

                  (ii)     With  respect  to  paragraphs  30-32  of the  Amended
                           Amended  Statement  of Claim these  defendants  state
                           that  if the  Court  determines  there  should  be an
                           adjustment  to the  joint  account  and  the  carried
                           interest  account to reduce  the amount of  otherwise
                           recoverable  operational costs as pleaded,  then such
                           adjustment and this resulting claim,  demand, suit or
                           action arises out of Columbia's  operation  under the
                           1977   Agreement.   Particulars   of  the   aforesaid
                           operation   alleged  by  these   Defendants   against
                           Anderson  include those matters  alleged in paragraph
                           31 of the Amended Amended Statement of Claim.

         (b)      Alternatively or further:

                  (i)      On February 1, 1977 Anderson,  in accordance with the
                           terms  of  the  Columbia  Farmout,  agreed  to act as
                           operator and conduct  operations in  accordance  with
                           the 1959  Agreement,  and  accordingly  is liable for
                           gross  negligence in carrying out or failing to carry
                           out its duties;


<PAGE>

                  (ii)     With  respect  to  paragraphs  30-32  of the  Amended
                           Amended  Statement  of Claim these  defendants  state
                           that  if the  Court  determines  there  should  be an
                           adjustment  to the  joint  account  and  the  carried
                           interest  account to reduce  the amount of  otherwise
                           recoverable  operational costs as pleaded,  then such
                           adjustment   is    necessitated    by   damages   and
                           expenditures  caused by acts and failures of Anderson
                           which   constitute   gross  neglect  under  the  1959

BACKGROUND

8. Amoco Canada, Amoco Resources (formerly Dome),  Anderson (formerly Columbia),
Imperial  (formerly Esso), and Mobil and Mobil Resources carrying on business in
partnership as Mobil Oil Canada Properties, are currently interest owners in the
nature of a working  interest in properties now known as the  Kotaneelee  lands,
located in the Yukon Territory  (hereinafter referred to as the "current working
interest owners").  Anderson (formerly  Columbia) has been the managing operator
of the Kotaneelee lands since on or about February 1, 1977.

9. The Plaintiffs  were formerly the only working  interest owners and currently
hold an  interest  in the  nature of a 33 1/3%  carried  interest  in these same
properties  in the  Kotaneelee  area.  Of the 33 1/3% carried  interest,  Canada
Southern holds a 2 2/3% carried  interest and a 2/3% carried interest as trustee
for Magellan and Pantepec respectively.

10. The  Kotaneelee  lands were  acquired and held by Canada  Southern  prior to
1959,  as part of oil  and  gas  permits  granted  in the  Yukon  and  Northwest
Territories.  Canada Southern  conducted  exploration  upon the Kotaneelee lands
prior to any involvement of the Defendants.


GAS MARKETING OBLIGATIONS

11. In 1959,  pursuant to an oil and gas exploration,  development and marketing
contract dated as of May 28, 1959 (the "1959 Agreement"),  the Plaintiffs agreed
to transfer a 50%  interest in the oil and gas  permits to the  predecessors  or
assignors of Amoco Canada,  Amoco Resources  (formerly Dome) and Mobil Resources
(formerly Canadian Superior).  One of the express recited considerations for the
transfer  of this 50%  interest  was that the  transferees  would,  pursuant  to
Article III 3.1(D) ". . . assure the earliest feasible development and marketing
of oil and/or gas found on the properties."


<PAGE>

12. This express  consideration was a fundamental term of the 1959 Agreement and
the Plaintiffs  relied upon the assurance that the properties would be developed
and gas sold at the earliest feasible opportunity.

12A. It was a further express  provision of Clause L of Schedule "B" to the 1959
Agreement  that each of the  parties  to the  agreement  would  share  available
markets for production with the other parties, including the Plaintiffs.

13. Amoco Production and Amoco Resources  (formerly Dome) expressly agreed to be
bound by all the terms and provisions of the 1959 Agreement,  when they acquired
their interests by assignment,  in the Kotaneelee lands, in the period from 1959
to  1966,  and they  were  expressly  bound to  assure  such  earliest  feasible
development  and marketing of Kotaneelee  oil and/or gas, for the benefit of the
Plaintiffs.  Amoco  Canada as the  assignee  and  successor in interest to Amoco
Production is bound by all the terms and provisions of the 1959 Agreement. Amoco
Resources as the assignee and  successor in interest to Dome is bound by all the
terms and provisions of the 1959 Agreement.

14. Mobil Resources (formerly Canadian Superior) as the successor in interest or
assignee of Alminex Limited,  one of the original parties to the 1959 Agreement,
is bound by such party's  assurance to develop and market  Kotaneelee gas at the
earliest feasible time. Mobil and Mobil Oil Canada Properties, as the successors
in  interest  or  assignees  of Mobil  Resources,  are  bound by the  terms  and
provisions  of the 1959  Agreement.  Alternatively,  Mobil and Mobil Oil  Canada
Properties  have assumed and agreed to be bound by all duties,  obligations  and
liabilities under the 1959 Agreement.

15. The 1959  Agreement  was modified by an agreement in writing  dated April 1,
1966,  in which  the  Plaintiffs'  50%  interest  in the  Kotaneelee  lands  was
converted  to a 50%  interest  in the  nature of a carried  interest  (the "1966
Agreement"). From that date to the present, the Plaintiffs have had no rights in
the  operation  of the  properties,  save and  except for a vote on which of the
current  working  interest  owners  would be manager  operator,  if the existing
operator  resigned or was  replaced,  and certain  other  options.  In all other
respects,  the Plaintiffs  relied upon the working interest owners who exercised
their discretion concerning operations.


<PAGE>

16. Anderson (formerly Columbia) acquired an interest in the nature of a working
interest in the  Kotaneelee  lands  pursuant to an  agreement  in writing  dated
February 1, 1977 (the "1977 Agreement").  Anderson (formerly Columbia) agreed to
drill a test well on the  Kotaneelee  lands and to act as  managing  operator of
those lands and it further agreed to conduct all  operations in accordance  with
the terms and  provisions  of the 1959  Agreement,  as  modified.  In turn,  the
Plaintiffs  again agreed to reduce their interest in the Kotaneelee  lands to an
interest in the nature of 33 1/3% carried interest.

17. Anderson (formerly Columbia), either expressly or impliedly, agreed with the
Plaintiffs  that it would be bound by the  obligation  to  assure  the  earliest
feasible development and marketing of oil or gas from the Kotaneelee lands.

17A. In addition,  Anderson  (formerly  Columbia) claims a further 1.69% working
interest  in the  Kotaneelee  lands,  which it alleges  was  acquired  from Dome
pursuant to an agreement in writing dated November 13, 1970.  Anderson (formerly
Columbia)  agreed that, upon earning its interest,  it would assume and agree to
be bound by the terms and provisions of the 1959 Agreement, as amended.

18.  Imperial  (formerly  Esso)  acquired an interest in the nature of a working
interest in the Kotaneelee lands by assignment from Imperial Oil Limited,  in or
around 1978, Imperial Oil Limited, in turn, acquired its interest by transfer or
assignment from Anderson  (formerly  Columbia),  in or around 1977.  Since 1978,
Imperial  (formerly  Esso) has taken an active role in discussions and decisions
relating to the operation of the Kotaneelee lands and it is bound,  expressly or
impliedly, by all the terms and provisions of the 1959 Agreement which remain in
effect.

18A. Further,  or in the alternative,  the Plaintiffs plead and rely upon Clause
CC.6 of Schedule "B" to the 1959 Agreement which provides that:

         "CC.6 All terms, covenants, provisions and conditions of this Agreement
         shall run with  and be binding  upon the  said lands  during  the  term
         hereof."

Accordingly,  all  of  the  Defendants  who  claim  a  working  interest  in the
Kotaneelee  lands are expressly  bound by all terms,  covenants,  provisions and
conditions of the 1959 Agreement, which run with and bind the lands.


<PAGE>

18B. Further, or in the alternative, the Plaintiffs plead and rely upon Clause Q
of Schedule "B" to the 1959 Agreement which provides that:

         "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."

Those  Defendants who claim an interest in the Kotaneelee lands by assignment or
transfer are obligated to recognize  and accept all of the terms and  provisions
of the 1959 Agreement.

19. The  Plaintiffs  further  state  that the effect of the 1959,  1966 and 1977
Agreements is that the exploration, development and production of the Kotaneelee
lands was to be a joint venture  between the Plaintiffs and the current  working
interest owners,  for the benefit of all parties.  As such, the Plaintiffs state
that the current working  interest owners owe a fiduciary duty to the Plaintiffs
with respect to any dealings with the Kotaneelee lands.

20. Further,  the current working interest owners, by undertaking to produce and
sell  gas at  the  earliest  feasible  time,  and by  agreeing  to  operate  the
Kotaneelee lands,  become the agents of the Plaintiffs to sell or market any gas
found in the Kotaneelee  lands. As agents,  the current working  interest owners
owe the  Plaintiffs a fiduciary  duty,  requiring  that they act with the utmost
good faith.

21.  Further,  the  Plaintiffs  placed their trust and confidence in the current
working interest owners and relied upon them to produce and market the gas found
in the Kotaneelee lands.  Canada Southern was informed by the managing operator,
and other  Defendants,  of efforts to market the gas  discovered and relied upon
these  reports.  As a result of those  dealings,  the current  working  interest
owners owe a fiduciary duty to the Plaintiffs.

2lA.  Further,  the terms and provisions of the 1966 Agreement  obligated  Amoco
Canada,  Amoco Resources  (formerly Dome) and Mobil Resources (formerly Canadian
Superior) to maintain the Kotaneelee lands in good standing,  to perform and pay
the cost of managing,  exploration  and  development  of the lands,  to maintain
accounts  and  render  statements  and to  generally  operate  the lands for the
benefit of the carried  interest  owners.  As such, the current working interest
owners owe a fiduciary duty to the Plaintiffs.


<PAGE>

22. In the  period  from  1977 to 1980,  three gas  wells  were  drilled  in the
Kotaneelee  field and it was known that there were extensive proven and probable
reserves  of  gas  in  the  structure  underlying  the  lands.  By  1980,  a gas
dehydration  system had been  constructed on the lands and the Kotaneelee  field
had been  tied  into the  Westcoast  Transmission  raw gas  pipeline,  which ran
through the field.

23. In the period from 1980 to 1991, the current working interest owners did not
market  or sell  any gas  from  the  Kotaneelee  lands,  except  to test the gas
dehydration system and for brief periods in 1979 and 1980,  notwithstanding that
the lands were ready and able to produce.

24. In November, 1986, Canada Southern, without any prior knowledge, was advised
by  Anderson  (formerly  Columbia)  that a current  working  interest  owner had
declined a market  for  Kotaneelee  gas,  earlier  in 1986,  as to which  Canada
Southern had no knowledge.

25. In 1988, Canada Southern,  without any prior knowledge,  discovered that the
operator of the field, Anderson (formerly Columbia),  had thereafter refused, in
1986,  to undertake  any further  efforts to market  Kotaneelee  gas,  after the
market had been declined earlier in 1986.

26. Except as referred to in paragraph 23 hereof,  the Kotaneelee lands were not
put into production  until 1991,  after the  commencement of these  proceedings,
notwithstanding  that  the  gas  fields  directly  to the  north  and  south  of
Kotaneelee,  in which the Defendant  Amoco Canada held a 100% working  interest,
have been produced and marketed to near depletion and  notwithstanding  that the
current working interest owners have,  since 1980,  produced and market gas from
other  fields in which  they hold an  interest.  The gas field to the  immediate
south of the  Kotaneelee  field has recently been reopened and gas is apparently
being  marketed  from  that  field.  Although  gas is now  being  marketed  from
Kotaneelee,  there is no assurance  that the lands will be kept in production by
the  current  working  interest  owners,  notwithstanding  that  there are other
available markets for the gas.

27. The Plaintiffs  state that the current working interest owners have breached
their fiduciary duty, have breached the express agreement to assure the earliest
feasible  marketing of gas from the  Kotaneelee  lands and have  breached  their
obligation to act as prudent operators, by:

         (a)      refusing or failing to sell gas from the Kotaneelee lands;


<PAGE>

         (b)      declining the market of gas in 1986;

         (c)      refusing or  declining  other  potential  markets for gas, the
                  particulars  of which will be  provided  prior to the trial of
                  this action;

         (d)      refusing to undertake any further  efforts to market gas after
                  1986;

         (e)      failing  to  make   full  and   complete  disclosure   to  the
                  Plaintiffs;

         (f)      producing and marketing gas from fields other than Kotaneelee,
                  in direct conflict with the duty owed to the Plaintiffs;

         (g)      failing to act in good faith or in the  best  interests of the
                  Plaintiffs in dealings with the Kotaneelee lands;

         (h)      failing to share available markets for production.

28. By reason of the matters  aforesaid,  the Plaintiffs  have suffered loss and
damage,  equal to the  Plaintiffs'  interest in the  proceeds  from sales of gas
which should have been realized and have been  deprived of all economic  benefit
in the Kotaneelee lands.

29. By reason of the matters  aforesaid,  the Plaintiffs  state that the actions
and  decisions  of the current  working  interest  owners  constitute a complete
repudiation  of the joint  venture to produce  and sell gas from the  Kotaneelee
lands and are in disregard of the fiduciary duty owed to the Plaintiffs.


THE CARRIED INTEREST ACCOUNT

30. Further,  as to the Plaintiffs  interests,  the 1959 Agreement,  as amended,
provided  that a portion  of  certain  expenditures  made for the joint  account
("operational   costs")  would  be  deducted   from  revenues  from   production
("operational revenues"), before any revenue would be paid to the Plaintiffs.


<PAGE>

30A. As of June 30, 1988,  Anderson (formerly  Columbia) reported that the total
operational   costs   incurred  in  relation  to  the   Kotaneelee   lands  were
$63,504,409.00,  including capital costs and operating  expenses for three wells
and a  dehydration  facility.  This  amount  has  not  been  challenged  by  the
Plaintiffs and they acknowledge that these  expenditures are properly charged to
the carried interest account.

30B. Since the commencement of these proceedings,  Anderson (formerly  Columbia)
has reported  that the total  operational  costs have now  increased to over $97
million,  without the drilling of any new wells or any further  development work
in the field.

31. The  Plaintiffs  dispute,  take  exception to and  challenge the increase in
total  operational  costs.  The  increase,  as reported  by  Anderson  (formerly
Columbia),  amounts to over $34 million.  The Plaintiffs  claim an adjustment to
the  joint  account  and the  carried  interest  account,  to  reduce  the total
operational costs from over $97 million, to the amount of $63,504,409.00,  which
was  reported  in 1988.  The  particulars  of this claim for  adjustment  are as
follows:

         (a)      The parties  expressly agreed that operational costs would not
                  include  damages  or loss  which  could  have been  controlled
                  through the exercise of reasonable  diligence by the operator.
                  Certain of the costs which the current working interest owners
                  seek to charge  to the  joint  account  and  recover  from the
                  Plaintiffs  are for  damages  or loss  which  could  have been
                  avoided  through  reasonable  diligence.  In  particular,  the
                  operator failed to take any steps to protect wells,  that were
                  shut-in, from corrosion.

         (b)      Further,  it was not an express  or  implied  term of the 1966
                  Agreement that "operational costs," as defined therein,  would
                  include unnecessary, improper or wasteful expenditures.

         (c)      Alternatively, the current working interest owners owed a duty
                  in law, as fiduciaries,  or otherwise,  to the Plaintiffs,  to
                  avoid or prevent  over-expenditure  or waste in the conduct of
                  operations  that might be chargeable  to the carried  interest
                  owners.


<PAGE>

         (d)      The Plaintiffs state that unnecessary,  improper, and wasteful
                  costs have been  incurred  in  developing  and  operating  the
                  field.  The current  working  interest  owners failed to avoid
                  gross over-expenditure in the conduct of operations.

         (e)      The unnecessary,  improper and wasteful  expenditures,  to the
                  present knowledge of the Plaintiffs, resulted from among other
                  things:

                  (i)      The entire  delegation of the  management and control
                           of operations to outside contractors;

                  (ii)     failing  to  properly   supervise  or  control  field
                           operations;

                  (iii)    failing to conduct adequate on-site supervision:

                  (iv)     failing to establish cost controls or to follow sound
                           business practices with respect to expenditures;

                  (v)      The  waste  of  the  investment  in  the  dehydration
                           facility  which  had to be  re-built  due to  design,
                           construction  and operation  defects and which is now
                           reported to have cost over $20 million;

                  (vi)     shutting-in   the  wells  without  proper   corrosion
                           protection,  which  resulted  in  the  waste  of  the
                           drilling and completion costs of those wells;

                  (vii)    the  over-expenditures  on the I-48 well which had to
                           be  side-tracked  and  recompleted,   at  a  cost  of
                           approximately  $10  million,  because it was  neither
                           properly  suspended  nor  put  into  production  when
                           markets were available.


<PAGE>

         (f)      Further,   or  in  the   alternative,   the  carried  interest
                  provisions in Schedule D to the 1959  Agreement  provided that
                  operational  costs  could  not be  deducted  from  operational
                  revenues unless certain  statements and accounts were rendered
                  to the Plaintiffs and certain conditions were met. Since 1988,
                  the current  working  interest  owners have failed to maintain
                  proper  accounts  and the  required  statements  have not been
                  rendered to the  Plaintiffs.  In addition,  the conditions for
                  the recording and charging of operational costs to the carried
                  interest owners were not fulfilled by the Defendants.

32. It is  anticipated  that when and if revenues are recovered  from the field,
the  current  working  interest  owners  will  attempt to recover the entire $97
million of reported  operational  costs.  The result will be that the Plaintiffs
will be denied the right to receive their full 33 1/3 percent  carried  interest
share of revenues from the Kotaneelee lands. Accordingly, the Plaintiffs seek an
order  of  this  Honourable  Court  declaring  that  the  proper  amount  of the
operational   costs  which  may  be  deducted  from   operational   revenues  is
$63,504,409.00  and  adjusting the joint  account and carried  interest  account
accordingly.

33. The  Plaintiffs  propose  that the trial of this action be held at the Court
House, in the City of Calgary, in the Province of Alberta.

         WHEREFORE the Plaintiffs claim against the Defendants:

         (a)      an order  vesting the  interests  of the  Defendants,  in  the
                  Kotaneelee lands,  in the Plaintiffs,  for breach of fiduciary
                  duty;

         (b)      in the  alternative,  a declaration  that the Defendants  hold
                  their  interests  in the  Kotaneelee  lands in  trust  for the
                  Plaintiffs  and an order  directing  the  conveyance  of those
                  interests to the Plaintiffs;

         (c)      in the  alternative,  an order  rescinding the 1959,  1966 and
                  1977 Agreements and terminating any interest of the Defendants
                  in the Kotaneelee lands, for breach of fiduciary duty;


<PAGE>

         (d)      in the alternative,  a declaration that the Defendants have no
                  claim to any interest in the Kotaneelee field.

         (e)      further,  or in the  alternative,  a mandatory order requiring
                  and  directing  the  Defendants  promptly  market gas from the
                  Kotaneelee  lands,  in  default of which the  interest  of the
                  Defendants in the Kotaneelee lands shall be forfeited;

         (f)      in  the  alternative,  an  order  directing  division  of  the
                  Kotaneelee lands between the Plaintiffs and the Defendants;

         (g)      damages for breach  of  fiduciary  duty,  in  an  amount to be
                  proven at the trial of this action;

         (h)      in the alternative,  damages  for  breach  of  contract in the
                  amount to be proven at the trial of this action;

         (i)      an order declaring that the proper amount of operational costs
                  included in the carried interest account which may be deducted
                  from operational  revenues before any revenues are paid to the
                  Plaintiffs is $63,504,409.00;

         (j)      an order that all necessary accounts,  inquiries and direction
                  may be taken, made or given;

         (k)      interest  on  any  damages  awarded  herein  pursuant  to  the
                  Judgment Interest Act, S.A. 1984, c.J-0.5;

         (l)      costs of this action on a solicitor/client basis; and,

         (m)      such  further and other  relief as this  Honourable  Court may
                  deem just.

         DATED at the City of Calgary in the  Province of Alberta,  this 7th day
of March, 1990, AND DELIVERED BY MESSRS. BALLEM McDILL MacINNES EDEN, Barristers
and Solicitors,  solicitors for the Plaintiffs,  whose address for service is in

AMENDED  STATEMENT OF DEFENCE  OF ANDERSON OIL AND GAS INC.  (formerly  COLUMBIA
GAS DEVELOPMENT OF CANADA LTD.)  TO  AMENDED  THIRD PARTY  NOTICE FILED BY AMOCO
CANADA  PETROLEUM  COMPANY  LTD.,  AMOCO  PRODUCTION  COMPANY  AND  AMOCO CANADA
RESOURCES LTD. (formerly DOME PETROLEUM LIMITED)


1. Except as hereinafter  admitted,  or as admitted in the Amended  Statement of
Defence filed by Anderson Oil and Gas Inc. (formerly Columbia Gas Development of
Canada Ltd.)  ("Columbia"),  Columbia  denies each and every  allegation  in the
Amended Amended Statement of Claim and the Amended Third Party Notice.  The said
Amended Statement of Defence is incorporated herein by reference.

2.  Columbia  denies the  liability of the  defendants  Amoco  Canada  Petroleum
Company Ltd. ("Amoco Canada"), Amoco Production Company ("Amoco Production") and
Amoco  Canada   Resources  Ltd.   (formerly  Dome  Petroleum   Limited)  ("Amoco
Resources") to the Plaintiffs.

3. In the alternative to paragraph 2 herein, if any of the said defendants Amoco
Canada, Amoco Production or Amoco Resources are liable to the Plaintiffs,  which
is not admitted but is expressly denied, the said defendants are not entitled to
claim  contribution  and  indemnity  from  Columbia  for any portion of the said
liability.

4. In answer to paragraphs 2 and 3 of the Amended Third Party  Notice,  Columbia
specifically  denies that there is any shared obligation as alleged.

5. In  answer  to  paragraph  4 of the  Amended  Third  Party  Notice,  Columbia
specifically denies any obligation as alleged. Columbia admits entering into the
Columbia  Farmout,  but  denies  that the  Columbia  Farmout  has been  properly
characterized  or described in the Amended  Third Party  Notice.  Columbia  will
refer at trial to the Columbia Farmout for its precise terms and effect.

6.  Columbia  specifically  denies any  agreement to indemnify and hold harmless
Amoco Canada or Amoco  Resources as alleged in paragraph 4 of the Amended  Third
Party  Notice.  The  indemnity  given by Columbia  was  restricted  in scope and
duration in the following ways:


<PAGE>

         a) The indemnity was restricted to claims by third parties  arising out
         of Columbia's  operations prior to earning.  Earning has occurred,  and
         the indemnity is therefore no longer in force and effect.

         b) In the  alternative,  if the  indemnity  extends  to claims by other
         parties to the Columbia Farmout, which is not admitted but is expressly
         denied, it was limited to claims prior to earning,  and is therefore no
         longer in force and effect.

         c) In the  alternative  to (a) and (b),  if the  indemnity  is still in
         force and effect,  which is not admitted but is expressly denied, it is
         limited to third party claims arising from Columbia's operations of the
         Block I lands following  earning,  and is not related in any way to the
         claims in this action.

         d) In the  alternative  to (c), if the  indemnity is still in force and
         effect,  and if it extends to claims by other  parties to the  Columbia
         Farmout,  all of which is not  admitted but is  expressly  denied,  the
         indemnity is limited to claims  arising from  Columbia's  operations of
         the Block I lands,  and is not related in any way to the claims in this
         action.

         e) The  indemnity  relates  only  to  claims  arising  from  operations
         actually  undertaken by Columbia,  and not to any claims for operations
         not undertaken.

6A. In further answer to paragraph 4 of the Amended Third Party Notice,  even if
the Plaintiffs are granted an adjustment of the Carried Interest  Account,  such
adjustment  would not reduce the  liability of Amoco  Canada or Amoco  Resources
with  respect  to the  Joint  Account,  nor  would  this  provide  any basis for
indemnity.  As among Columbia,  Amoco Canada and Amoco Resources,  the amount of
the Joint Account is established by  expenditures  made by Columbia on behalf of
the Joint Operators.

6B.      The right of Amoco Canada and Amoco Resources to challenge  Operational
Costs is as  set out in  Clause 4  of the  relevant  Accounting Procedure  which
states:


<PAGE>

         "...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 with 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..."

6C. Neither Amoco Canada nor Amoco  Resources has commenced an audit or made any
written  exception  to  expenditures  since June 30,  1988.  These  amounts  are
therefore conclusively presumed to be true and correct.

6D. In the alternative and in further answer to paragraph 4 of the Amended Third
Party Notice,  the  Plaintiffs  have not alleged gross  negligence or willful or
wanton misconduct.  Columbia will seek further  particulars of these allegations
in the Amended  Third Party Notice.  Furthermore,  since these  allegations  are
based on a different  cause of action than the  Plaintiffs'  claim,  they cannot
form the basis for a claim for  indemnity.  Further or in the  alternative,  the
liability  of  Columbia  as  operator  is limited to where there has been fraud,
dishonesty or gross neglect, or where there has been failure to remedy a default
after  receipt of  written  notice of such  default.  No  allegations  of fraud,
dishonesty or gross neglect have been pleaded by the  Plaintiffs,  and no notice
of default has been given by the Plaintiffs, Amoco Canada or Amoco Resources for
any operations for any operations conducted by Columbia.

6E. In further  answer to  paragraph 4 of the Amended  Third Party  Notice,  the
Production  Facilities Agreement does not form an basis for the alleged claim of
indemnity.  Furthermore,  neither Amoco Canada nor Amoco Resources has commenced
any audit of expenditures, nor has any written execution or claim for adjustment
been made.  Statements rendered by Columbia are therefore  conclusively presumed
to be true and correct.


<PAGE>

7. In answer to the  entire  Amended  Third  Party  Notice,  Columbia  has never
assumed any obligation, by way of indemnity or otherwise, relating to Clause III
3.1(D) of the 1959  Agreement.  But  although  Columbia  has never  assumed  any
obligation to assure the earliest  feasible  development and marketing of oil or
gas,  Columbia  has in fact made every effort to market and develop the gas from
the Block I lands. Columbia has continually researched marketing  opportunities,
Columbia has from time to time  proposed  marketing  opportunities  to the other
working interest owners, and there has been production and marketing of gas from
the Kotaneelee lands.

8. If Amoco Canada,  Amoco  Production or Amoco  Resources have any liability to
the  Plaintiffs,  which  is not  admitted,  but  is  specifically  denied,  this
liability was caused by or contributed to by the actions of Amoco Canada,  Amoco
Production or Amoco Resources or any one or more of them, and not by any actions
of Columbia.

                                   Particulars

         a) Amoco Canada,  Amoco  Production or Amoco  Resources,  or any one or
         more of them,  developed  and marketed gas from other lands in the area
         in which they had an interest and not from the Kotaneelee area;

         b) Amoco Canada,  Amoco  Production or Amoco  Resources,  or any one or
         more of them rejected gas marketing proposals made by Columbia;

         c) Amoco Canada,  Amoco  Production or Amoco  Resources,  or any one or
         more of them  initiated  the  decision  to require  the gas plant to be
         taken out of service;  this decision was voted on  affirmatively by all
         parties except Columbia;

         d) Amoco Canada,  Amoco  Production or Amoco  Resources,  or any one or
         more of  them  (hereinafter  referred  to as  "the  Amoco  Companies"),
         resisted Columbia's efforts to put the gas plant back in service and to
         produce and market the gas. In particular,

                  i)  The  Amoco  Companies   initially   refused  to  authorize
                  expenditures  to put the gas plant back in service  until such
                  time as the Production Facilities Agreement was entered into;


<PAGE>

                  ii) The Amoco Companies refused to include any provision as to
                  sharing of markets in the Production Facilities Agreement; the
                  Amoco Companies indicated that they wanted to market their own
                  share of production of gas;

                  iii) Once the  Production  Facilities  Agreement  was  signed,
                  Amoco  Canada  moved  to take  over  operatorship  under  that
                  Agreement  on the  limited  grounds of supposed  greater  cost
                  efficiency.  Amoco  Canada,  Esso and Mobil voted in favour of
                  Amoco Canada becoming Operator under that Agreement,  Columbia
                  undertook to assign Operatorship to Amoco Canada at such times
                  as Amoco  Canada  (1)  agreed to  execute  Authorizations  for
                  Expenditure   committing  to  the  project,  (2)  Brought  its
                  outstanding  account into good standing,  (3) Assumed existing
                  third  party  obligations  already  in place  and (4)  Assumed
                  Operatorship of the entire project so that there would be only
                  one Operator. Amoco Canada did not agree to these requirements
                  and  specifically  advised  Columbia  that it did not  want to
                  operate  the wells.  Amoco  Canada has  subsequently  executed
                  Authorizations  for  Expenditure  and has  paid  its  share of
                  expenditures.

                  iv) In 1989, Columbia and Esso entered into one year contracts
                  for  marketing  Kotaneelee  gas to Canwest Gas Supply Inc. The
                  Amoco Companies  refused to sign similar contracts and did not
                  sign any other  contract so that in net result,  Columbia  and
                  Esso carried the Amoco Companies, crediting to them a share of
                  the revenue  received  under those  contracts,  and  depriving
                  Columbia of its full share of revenue, and reducing the amount
                  of revenue that would have been Operational  Receipts credited
                  to the Carried Interest Account had the Amoco Companies signed
                  a contract.

         e) Amoco Resources has at all times remained the operator of all lands,
         save and except to the extent of obligations assumed by Columbia in the
         Block I lands pursuant to the Columbia Farmout.


<PAGE>

8D. In further answer to the whole of the Amended Third Party Notice,  the Amoco
Companies have authorized all  expenditures  made for the Joint Account and have
paid their share of expenditures. The Amoco Companies were advised on an ongoing
basis of all operations and  activities,  and had the opportunity to participate
in decisions involving  operations and activities.  The Amoco Companies also had
full  opportunity  to audit the Joint  Account but chose not to do so. The Amoco
Companies  have also  acknowledged  in writing that they are satisfied  with the
operations conducted by Columbia.  Columbia has relied on this conduct of Amoco.
Amoco is therefore  estopped from now asserting that Columbia's  operations were
not carried out properly.

9. In further  answer to the entire  Amended Third Party  Notice,  any claim for
indemnity  against  Columbia is barred by the Limitation of Actions Act,  R.S.A.
1980,  c.L-15,  or the  Limitation  of Actions  Act,  R.S.Y.  1986,  c. 104,  or
alternatively by laches.

         WHEREFORE  Columbia  prays  that the claims  against it in the  Amended
Third Party Notice be dismissed  with costs in favour of Columbia on a solicitor
and client basis, or such other basis as to this Honourable Court may seem just.

         DATED at the City of Calgary, in the Province of Alberta, this 25th day
of January, 1994 AND DELIVERED by McCarthy Tetrault,  Barristers and Solicitors,
Solicitors for the Third Party Columbia, whose address for service is in care of
the said Solicitors at Suite 3300,421 Seven Ave. S.W., Calgary, Alberta T2P 4K9.
