ITEM 1.   BUSINESS

       GENERAL.

       Seven Seas Petroleum Inc. ("Seven Seas") is engaged in the exploration
and development of oil and gas properties outside of North America. Seven Seas,
through its subsidiaries, owns interests in seven prospective areas located in
Colombia, Australia and Papua New Guinea, all of which are in the initial stages
of exploration and development. Seven Seas and its subsidiaries are collectively
referred to herein as the "Company." Certain oil industry terms used herein are
defined in the Glossary of Technical Terms attached hereto as Appendix A.

       The Company's principal asset is a 57.7% interest in the Dindal
Association Contract and Rio Seco Association Contract (collectively, the
"Association Contracts") which are located in the Upper Magdalena Basin in
Colombia, approximately 90 kilometers northwest of Bogota. In 1996, two
exploratory wells were drilled on the Dindal block. The Company also holds the
following interests in exploratory oil and gas properties: an 11.875% interest
in the Tapir Association Contract in the Llanos Basin in Colombia; an 11.77%
interest in the EP381 Permit and in the Whicher Range Permit Application in
Perth Basin, Australia; a 20% interest in Block T27P in the Bass Basin, offshore
southern Australia; and a 100% interest in PPL-182 in southern Papua New Guinea.
For a description of the Company's interests in these properties, see
"Properties."

       The Company's primary business strategy is to explore and develop the
Dindal and Rio Seco Association Contracts in Colombia. The Company also intends
to explore its other oil and gas interests in Colombia, Australia and Papua New
Guinea and may acquire additional oil and gas exploration opportunities which
management believes have large reserve potential. Although this type of
exploration and development generally involves higher risks, in the view of
management, it holds the potential to produce greater economic rewards.

       SUMMARY OF PROPERTIES

       The following summary of the Company's properties is qualified in its
entirety by the more detailed information included herein under the headings
"Properties" and "Management's Discussion and Analysis of Financial Condition
and Results of Operations".

       DINDAL AND RIO SECO ASSOCIATION CONTRACTS, UPPER MAGDALENA BASIN,
COLOMBIA. The Company's principal asset is a 57.7% interest in the Association
Contracts which entitle the Company to engage in exploration, development and
production activities in approximately 106,000 acres located in the oil
producing Upper Magdalena Basin, about 90 kilometers northwest of Bogota. Recent
discoveries in the Magdalena Basin include Amoco's Opon Field, located
approximately 170 kilometers north of the prospect area, and Lasmo's
Venganza/Revancha complex, located approximately 150 kilometers to the south.

       Three wells have been drilled, to date, on the Dindal block under the
Dindal Association Contract. The El Segundo #1 well commenced drilling on
December 10, 1995, reached total depth in mid-January 1996 and was placed on a
long-term production test in July 1996. The El Segundo #2 well was completed for
testing in November 1996 and a long-term production test commenced in February
1997. The Escuela #1 well, which was drilled in 1994 prior to the acquisition of
an interest in the block by the Company, was plugged and abandoned as a dry
hole. The following table provides a summary of the El Segundo #1 well and the
El Segundo #2 wells:

        El Segundo #2    November 1996          6,820             8,948

(1) References are from production testing only and are not necessarily
indicative of flow rates that may be utilized during long-term production.
Production tests are conducted to obtain an indication of the flow capacity of
individual wells and to give an indication of reservoir quality. Actual
producing rates from individual wells will depend on the results of an
integrated reservoir study and an engineering production plan which will
incorporate data from all wells in the field in a development plan to maximize
economic recovery of oil from the reservoir.

       The first well for the Rio Seco Association Contract, the Tres Pasos #1
well, is expected to commence drilling operations in May 1997. The Tres Pasos #1
well is an appraisal well for the oil accumulation discovered in the Dindal
block and is located some 2.5 kilometers northwest of the surface location of
the El Segundo #1 and #2 wells. The Company plans to drill up to two additional
wells on the Dindal block in 1997 and to acquire permits for a seismic survey,
in each case, to determine the potential size of the oil accumulation by further
delineating the areal extent and reservoir geology of the structure. The Company
may expend up to $12 million on the exploration of the Dindal and Rio Seco
blocks in 1997, including the cost of two wells, estimated at approximately $4.4
million, which are required to be drilled under the terms of the Association
Contracts.

       TAPIR ASSOCIATION CONTRACT, LLANOS BASIN, COLOMBIA. The Tapir Association
Contract is located in the Llanos Basin of east central Colombia and is crossed
by two oil pipelines carrying production from nearby oil fields. An exploratory
well is expected to commence on the Tapir block in late 1997 or in the first
quarter of 1998 following receipt of required permits from the Ministry of the
Environment. The estimated cost to the Company of this well is approximately
$250,000. An existing discovery well, the Macarenas #1, was drilled on the Tapir
block in 1993 and produced 320 BOPD in a short-term test, but was not completed
for production. Since the well was drilled and tested, additional oil pipeline
infrastructure has been built in the area. The operator plans to place the well
on long-term production test after the completion of the exploratory well to
determine sustainable production rates and the extent of the reservoir.

       PERTH BASIN, EP381 AND WHICHER RANGE PERMITS, AUSTRALIA. The Company
currently holds an 11.765% working interest in EP 381, an exploration permit
covering 455,405 acres, and in the Whicher Range Permit Application, covering
439,141 acres, both of which are located in the Perth Basin, Western Australia.
The greater Perth Basin produces gas and oil from accumulations onshore in a
region north of the Company's permit areas and north of the city of Perth. The
Whicher Range Permit Application, which adjoins EP381 to the north and contains
the Whicher Range Gas Field discovered by Union Oil of California in 1968, was
reserved for the applicants pending resolution of native claims pursuant to the
Australian NATIVE CLAIMS ACT 1993.

       The principal exploration interest in the EP 381 and the Whicher Range
Permit areas is for natural gas generated in Permian coal measures and
reservoired within adjacent Permian

                                    - 2 -
<PAGE>
sandstones. The operator of the permit areas has conducted reservoir studies on
the Whicher Range Permit Application area, the results of which indicate that
the use of different drilling technologies and newer completion techniques could
make the Whicher Range Gas Field economic to develop. Based on this technical
assessment and the market for natural gas now believed to be available in the
area, the partners plan to re-enter and test the Whicher Range #1 well in 1997.
If this re-entry and test is successful, the parties may drill an additional
well in late 1997 and initiate additional seismic programs in the block. In
addition, a new seismic study was commenced in March 1997 to delineate further
prospects in the EP381 prospect area. In May 1995, the Scott River #1 well was
drilled in the southern portion of EP 381, encountered Permian sandstones which
had sub-commercial saturations of natural gas and was abandoned.

       BASS BASIN, BLOCK T27P, AUSTRALIA. The Company holds a 20% working
interest in Block T27P, a 1.8 million acre block in about 70 meters of water, in
the Bass Basin, the central of three basins offshore southern Australia. The
easternmost basin is the Gippsland Basin where BHP Petroleum and Esso have a
series of large oil and gas fields. The westernmost basin is the Otway Basin,
the site of recent gas discoveries by BHP Petroleum and others which will likely
serve the South Australia and Victoria gas market. The Bass Basin has been the
site of a series of gas and oil shows and discoveries, including the Yolla
Field, which is adjacent to Block T27P. The Yolla Field was discovered by Amoco
in the mid-1980's but has not yet been appraised or developed for production.

       Globex Exploration, the operator of the permit with a 80% working
interest, has completed a 1,000 kilometer 2D seismic program in the block. The
remaining work commitment in the block consists of a 3D seismic survey and two
exploration wells. Globex Exploration has selected a drillable prospect
approximately 10 kilometers north of the Yolla Field, and is seeking additional
participants in the block to share the cost of an exploratory well which is
estimated to be approximately $5 million. As suitable drilling rigs are not
available in the near term, Globex has applied for a permit extension in the
block until a suitable rig can be contracted.

       PERMIT PPL-182, PAPUA NEW GUINEA. The Company was granted exploration
permit PPL-182 in southern Papua New Guinea effective June 11, 1996. The permit
covers an area of 1,200,000 acres located both onshore and offshore in the Fly
River Delta and the Gulf of Papua. The nearest discovery to the permit area is
the Pandora Gas Discovery located in PPL-82 approximately 150 kilometers to the
east in the Gulf of Papua.

       Past exploration activity within PPL-182 has resulted in the acquisition
of seismic data and the drilling of several exploration wells. The Company's
first year work program consists of a geological and geophysical review of
existing data. Based on the results of this study, the Company will decide
whether to proceed with the second year's work commitment which provides for
seismic reprocessing and acquisition of a high resolution aeromagnetic survey
and is expected to cost approximately $500,000. The Company plans to secure an
industry partner or partners to underwrite a significant portion of future
exploration costs.

       RISKS ASSOCIATED WITH THE COMPANY'S BUSINESS.

       EXPLORATION AND DEVELOPMENTAL RISKS. Oil and gas exploration and
development is a speculative business and involves a high degree of risk. The
Company has expended, and plans to continue to expend, significant amounts of
capital on the acquisition and exploration of its properties. Even if the
results of such activities are favorable, as in Colombia where the Company has
made an oil discovery, subsequent drilling at significant costs must be
conducted on the property to determine if commercial development of the property
is feasible. Oil and gas drilling may involve unprofitable efforts, not only
from dry wells but from wells that are productive but do not produce sufficient
net revenues to return a profit after drilling, operating and other costs. It is
difficult to project the costs of implementing an exploratory drilling program
due to the inherent uncertainties of drilling in unknown formations, the costs
associated with encountering various drilling conditions such as overpressured
zones and tools lost in the hole, and changes in drilling plans and locations as
a result of prior exploratory wells or additional seismic data and
interpretations thereof. Exploration of offshore oil and gas properties also
involves an increased degree of risk relative to onshore or close-to-shore
exploration primarily due to greater technical obstacles. The marketability of
oil and gas which may be acquired or discovered by the Company will be affected
by the quality and viscosity of the production and by numerous factors beyond
its control, including market fluctuations, the proximity and capacity of oil
and gas pipelines and processing equipment, government regulations, including
regulations relating to prices, taxes, royalties, land tenure, importing and
exporting of oil and gas and environmental protection. There can be no assurance
the Company will be able to discover, develop and produce sufficient reserves in
Colombia, Australia, Papua New Guinea, or elsewhere to recover the costs and
expenses incurred in connection with the acquisition, exploration and
development thereof and achieve profitability.

       NEED FOR ADDITIONAL FINANCING. The Company has no significant income
producing properties and its principal asset, the Dindal and Rio Seco blocks, is
in the early stage of exploration and development. Since inception through
December 31, 1996, the Company incurred cumulative losses of $4,314,622 and,
because of its continued exploration activities, expects that it will continue
to incur losses and that its accumulated deficit will increase until
commencement of production from the Dindal and Rio Seco blocks in quantities
sufficient to cover operating expenses related thereto. The exploration and
development of the Company's current properties and any properties acquired in
the future is expected to require substantial amounts of additional capital
which the Company may be required to raise through debt or equity financings,
encumbering properties or entering into arrangements where by certain costs of
exploration will be paid by others to earn an interest in the property. There
can be no assurance that the additional debt or equity financing expected to be
necessary to fund the Company's operations and obligations will be available to
the Company on economically acceptable terms. If sufficient funds cannot be
raised to meet the Company's obligations with respect to a property, the Company
may elect to forfeit its interest in such property. See"Management's Discussion
and Analysis of Financial Condition and Results of Operations."

       RISKS INHERENT IN FOREIGN OPERATIONS. There are risks inherent in the
fact that the Company has acquired and intends to continue to acquire interests
in oil and gas properties located outside of North America in some cases in
countries which may be considered politically and economically unstable.
Accordingly, the Company is subject to risks inherent in the ownership and
development of foreign properties including, without limitation, cancellation or
renegotiation of contracts, royalty and tax increases, retroactive tax claims,
expropriation, adverse changes in currency values, foreign exchange controls,
import and export regulations, 

                                    - 4 -
<PAGE>
environmental controls, and other laws, regulations or international
developments which may adversely affect the Company's properties. The Company's
operations and agreements may be governed by foreign laws and, in the event of a
dispute, the Company may be subject to the exclusive jurisdiction of foreign
courts or may not be successful in subjecting foreign persons to the
jurisdiction of courts in the United States. Certain of the properties for which
the Company has an application pending in Australia are the subject of native
claims which remain unresolved. In addition, there can be significant logistical
problems, costs and risks in conducting oil and gas activities in remote, rugged
and primitive regions such as Papua New Guinea, or in Colombia where the
Company's operations may be exposed to potentially detrimental activities by the
leftist guerrillas that have operated in the region for many years.

       DEPENDENCE ON ACTIVITIES IN COLOMBIA. The Company's success currently
depends to a high degree on its activities in Colombia. This dependence is
likely to be reflected in both the short-term performance and the Company's
long-term financial results. The Company currently intends to drill up to three
additional wells on the Dindal and Rio Seco blocks in 1997. The market price of
the Common Shares may significantly fluctuate based on the outcome of individual
wells.

       RISKS OF JOINT VENTURES. The Company has and expects to continue to
acquire only partial interests in oil and gas properties through joint venture
agreements with other oil and gas corporations which may, by the terms of such
joint venture agreements, be the operators of such programs. Although the
Company can take certain steps to determine if the risk of the program to be
conducted by the operator is appropriately spread over a number of prospects,
there can be no assurance that the risk will be so allocated, that the program
will be carried out by the operator in a manner deemed appropriate by the
Company or that the prospects will be successful. In addition, the Company's
ability to continue its exploration and development programs may be dependent
upon the decision of its joint venture partners to continue exploration and
development programs and to finance their portion of the costs and expenses of
the joint venture. If the Company's partners do not elect to continue and to
finance their obligations to the joint ventures, the Company may be required to
accept an assignment of the partners' interests therein and assume their
financing obligations or relinquish its interest in the joint venture.

       OPERATING HAZARDS AND UNINSURED RISKS. The Company is also subject to all
the risks normally incident to drilling for and producing oil and gas, including
hazards such as over-pressured formations, blowouts, cratering, fires, spills,
or other hazards or conditions, any of which could result in damage to or loss
of life or property. In accordance with industry practice, the Company is not
fully insured against these risks nor are all such risks insurable. Payment of
such potential liabilities would reduce the funds available for exploration,
drilling and production and could have a material adverse effect on the Company.

       LIMITED OPERATING HISTORY; DEPENDENCE ON KEY PERSONNEL. The Company has a
limited operating history and the success of the Company depends to a large
degree upon the efforts of its executive officers, the loss of whose services
could have a material adverse effect on the business and prospects of the
Company. The Company has entered into employment agreements with three of its
executive officers, the terms of which are more particularly described under
"Executive Compensation" below. The Company does not maintain key man insurance.

                                    - 5 -
<PAGE>
       POTENTIAL CONFLICTS. Certain of the directors of Seven Seas also serve as
officers, directors or consultants of other companies involved in natural
resource development which activities may be in competition with the Company and
may result in conflicts of interest. In the event a director has an interest in
an investment or proposed investment of the Company or other conflict of
interest, it is the Company's policy that such director not participate in the
Company's decision-making with respect thereto and that any transactions with
such officers or directors be on terms consistent with industry standards and
sound business practices.

       UNCERTAINTY OF ESTIMATES OF OIL AND NATURAL GAS RESERVES. Estimates of
the Company's proved oil and gas reserves and projected future net revenues
appearing elsewhere herein are based on reserve reports prepared by independent
petroleum engineers. The estimation of reserves requires substantial judgment on
the part of the petroleum engineers, resulting in imprecise determinations,
particularly with respect to new discoveries. Different reserve engineers may
make different estimates of reserve quantities and revenues attributable thereto
based on the same data. Estimates of proved undeveloped reserves, which comprise
a substantial portion of the Company's reserves, are by their nature less
certain. The accuracy of any reserve estimate depends on the quality of the
available data as well as engineering and geological interpretation and
judgment. Results of drilling, testing and production and changes in the
assumptions regarding decline and production rates, crude oil prices, revenues,
taxes, capital expenditures, operating expenses, geologic success and quantities
of recoverable crude oil may vary substantially from those assumed in the
estimates, may result in revisions to such estimates and could materially affect
the estimated quantities and related value of reserves set forth herein. The
estimates of future net revenues reflect oil and gas prices as of the date of
estimation, without escalation. There can be no assurance, however, that such
prices will be realized or that the estimated production volumes will be
produced during the periods indicated. Future performance that deviates
significantly from the reserve reports could have a material adverse effect on
the Company.

       SERVICE AND ENFORCEMENT OF LEGAL PROCESS. The Company is continued under
the laws of the Yukon Territory in Canada. Certain of the directors of the
Company, and certain experts utilized by the Company, are residents of Canada
and all or substantially all of such persons' assets are located outside of the
United States. As a result, it may be difficult for holders of the Common Shares
to effect service within the United States upon the directors and experts who
are not residents of the United States or to realize in the United States upon
judgments of courts of the United States against such persons and the Company
predicated upon civil liability under the United States federal securities laws.
The Company has been advised by its counsel that there is no assurance that
judgments of U.S. courts for liabilities predicated solely upon U.S. federal
securities laws will be enforceable in Canada against the Company or against any
of its directors or experts who are not residents of the United States.

       MARKETS. There is substantial uncertainty as to the prices which the
Company may receive for production from its existing oil reserves or from oil
and gas reserves, if any, which the Company may discover. The availability of a
ready market and the prices received for oil and gas produced depend upon
numerous factors beyond the control of the Company including, but not limited
to, adequate transportation facilities (such as pipelines), the marketing of
competitive fuels, fluctuating market demand, governmental regulation and world
political and economic developments. Prices for crude oil are subject to wide
fluctuation in response to relatively minor changes in supply and demand, market
uncertainty and a variety of additional factors that are beyond the control of
the Company. It is possible that, under market conditions prevailing in the
future, the production and sale of oil, if any, from certain of the Company's

                                    - 6 -
<PAGE>
properties may not be commercially feasible and the production of gas from the
Company's properties in Colombia, the Bass Basin and Papua New Guinea, is not
currently expected to be commercially feasible. The sale of oil from the
long-term production tests on the Company's properties in Colombia is currently
being sold to Ecopetrol.

       COMPETITION. Oil and gas exploration is extremely competitive in all of
its phases and particularly in exploration for and development of new sources of
crude oil and natural gas. The Company must compete with other companies that
are larger and financially stronger in acquiring properties suitable for
exploration, in contracting for drilling equipment and in securing trained
personnel. The Company is not a significant participant in the oil and gas
industry and it may not always be possible to acquire properties suitable for
drilling at economic prices.

       REGULATION. The Company's operations are subject to regulations imposed
by the local regulatory authorities including, without limitation, currency
regulation, import and export regulation, taxation and environmental controls.
The regulations also generally specify, among other things, the extent to which
properties may be acquired or relinquished, permits necessary for drilling of
wells, spacing of wells, measures required for preventing waste of oil and gas
resources and, in some cases, rates of production and sales prices to be charged
to purchasers. Specifically, Colombian operations are governed by a number of
ministries and agencies including Ecopetrol, the Ministry of Mines and Energy,
and the Ministry of the Environment. It is possible that the administration and
enforcement of current environmental laws and regulations or the passage of new
environmental laws or regulations in Colombia could result in substantial costs
and liabilities in the future or in delays in obtaining the necessary permits to
conduct and expand the Company's operations in such country. The Company has
experienced and may continue to experience delays in obtaining the necessary
environmental permits to expand its operations in Colombia. Operations in
Australia are governed by the State of Western Australia and by the State of
Tasmania. Operations in Papua New Guinea are currently governed by the
Department of Mining and Petroleum.

       HISTORY AND ORGANIZATIONAL STRUCTURE.

       Seven Seas became subject to the laws of the Yukon Territory in August
1996. Seven Seas was formed effective June 29, 1995 as a result of an
amalgamation (the "Amalgamation") 

                                    - 7 -
<PAGE>
under the laws of the province of British Columbia of Rusty Lake Resources Ltd.
("Rusty Lake") and Seven Seas Petroleum Inc. (the "Predecessor"), which was
incorporated under the laws of British Columbia on February 3, 1995. Under the
terms of the Amalgamation, the shares of Rusty Lake were exchanged for shares of
Seven Seas on a 35-to-1 basis, while the shares of the Predecessor were
exchanged for shares of Seven Seas on a 1-to-1 basis. Rusty Lake was formed by
an amalgamation of the Lithium Corporation of Canada, Limited and Stockgold
Resources Inc. under the laws of Ontario effective January 31, 1993. Prior to
the Amalgamation, Rusty Lake was a dormant mineral exploration and development
corporation whose common shares were quoted for trading on the Canadian Dealer
Network.

       The Company's principal executive office is located at Suite 960, Three
Post Oak Central, 1990 Post Oak Boulevard, Houston, Texas 77056 and its
telephone number is (713) 622-8218. The Company's operations are managed from
its Houston, Texas headquarters which consists of a staff of five employees,
using professional consulting services as needed. The Company also maintains an
office in Tulsa, Oklahoma with a staff of two employees.

       The following chart details the structure of Seven Seas and its

       MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS.

       LIQUIDITY AND CAPITAL RESOURCES.

       Since inception, the Company's activities have been funded primarily by
proceeds from private placements of the Company's securities resulting in
aggregate net cash proceeds of $19,000,000. In 1996, the Company acquired an
additional 36.7% interest in the Association Contracts in Colombia in exchange
for the issuance of the Company's securities valued at $153,091,430 in the
aggregate. Since inception the Company has expended approximately $7,533,200 for
the acquisition, exploration and development of its oil and gas properties
including approximately $5,934,600 with respect to its interests in Colombia,
approximately $454,600 with respect to its interests in Australia, approximately
$16,300 with respect to its 

                                    - 9 -
<PAGE>
interest in Papua New Guinea, and approximately $1,127,700 for exploration
activities in Argentina, Turkey and other countries, which have been expensed.

       COLOMBIA. The Company is required to drill an additional well on each of
the Dindal and Rio Seco blocks by August and September 1997, respectively, at an
estimated total cost to the Company of $4,400,000, to fulfill its work
commitments for the current contract year. In 1997, the Company also plans to
drill one additional well on the Dindal block and to perform a seismic survey at
an aggregate estimated cost to the Company of approximately $5,200,000. The
Company may also spend up to an additional $2,400,000 in operating costs. An
exploration well is also required to be drilled on the Tapir block at an
estimated proportionate cost to the Company of $250,000.

       In the third and fourth quarters of 1996, the Company had oil and gas
sales of $233,682 which pertained solely to production testing of the Company's
two wells in Colombia. Although the Company intends to continue to sell oil
resulting from long-term production tests, significant production from the El
Segundo #1 well and the El Segundo #2 well is not expected to commence until
further work is done to evaluate the field through the drilling of additional
wells, and producing facilities and pipelines have been constructed. Although
the Company has solicited proposals for various pipeline options, the substance
and timing of any decision regarding appropriate pipeline and production
facilities will depend on the results of the evaluation and appraisal of the
Company's discovery.

       AUSTRALIA. Upon issuance of the Whicher Range Permit Application, the
parties to the permit plan to re-enter the Whicher Range #1 well and perform an
acid-fracture stimulation of the productive intervals in the well at an
estimated cost to the Company of $380,000.

       The operator of the Bass Basin permit plans to drill an exploratory well
on a prospect located 10 kilometers north of the Yolla Field and has applied for
a permit extension until a suitable rig can be contracted. As the operator is
also seeking additional participants in the block to share the cost of the well,
which is estimated to be $5,000,000, the estimated cost of the well to the
Company cannot now be determined.

       PAPUA NEW GUINEA. The cost of the first year work program planned for PPL
182 in Papua New Guinea is estimated to be approximately $100,000. Based on the
results of the first year program, the Company will decide whether to proceed
with the second year work program which is expected to cost approximately
$500,000.

       The Company had working capital of approximately $9,100,000 as of
December 31, 1996 and realized an additional $3,500,000 in cash proceeds in
March 1997 as a result of the exercise of outstanding Common Share purchase
warrants. As the current funds on hand will not be sufficient to meet all
planned exploration costs, additional financing will be necessary to complete
these projects prior to the start-up of production and generation of cash flows
from the Company's oil discovery in Colombia in quantities sufficient to cover
operating expenses related thereto. In addition, it is anticipated that the
Company's future exploration activities with respect to its current properties
and any additional properties which may be acquired will require substantial
amounts of additional capital which the Company may be required to raise through
debt or equity financing, encumbering properties or entering into arrangements
whereby certain costs of exploration will be paid by others to earn an interest
in the property. There can 

                                    - 10 -
<PAGE>
be no assurance that the additional debt or equity financing expected to be
necessary to fund the Company's operations and obligations will be available to
the Company on economically acceptable terms. If sufficient funds are not
available to meet the Company's obligations with respect to a property, the
Company may elect to forfeit its interest in such property. The Company has no
significant lines of credit.

       RESULTS OF OPERATIONS.

       The Company reported a net loss of $2,194,637 ($.17 per share) for the
year ended December 31, 1996 which compares with a net loss of $2,119,985 ($.23
per share) for the period from inception through December 31, 1995. Oil and gas
revenues and production costs for 1996 were $233,700 and $252,500, respectively.
There were no oil and gas revenues or production costs for the year ended
December 31, 1995. Depreciation and amortization increased from $37,700 for the
period from inception through December 31, 1995 to $111,300 for the year ended
December 31, 1996 primarily as a result of the acquisition of GHK Company
Colombia, Esmeralda Limited Liability Company and Cimarrona Limited Liability
Company and the inclusion of a full year of depreciation expense for the
Company.

       Colombian oil production (net to the Company) of 14,188 barrels in 1996
pertained solely to the Company's share of oil produced from production testing
of the Company's two wells and was sold to Ecopetrol at an average price of
$16.47 per barrel.

       Interest income increased from $152,400 for the period from inception
through December 31, 1995 to $341,600 for the year ended December 31, 1996 as a
consequence of higher cash balances resulting from the private placements of the
Company's securities. General and administrative expenses increased from
$1,070,800 for the period from inception through December 31, 1995 to $2,452,500
for the year ended December 31, 1996 principally as a result of the expansion of
the Company's activities, the acquisition of an additional interest in the
Dindal and Rio Seco blocks in Colombia and costs associated with listing the
Company's securities on The Toronto Stock Exchange.

ITEM 3.  PROPERTIES.

COLOMBIA.

DINDAL AND RIO SECO ASSOCIATION CONTRACTS; UPPER MAGDALENA BASIN.

       INTRODUCTION AND REGIONAL OVERVIEW. Two major physiographic features
dominate the geography of Colombia. To the west lie the Andes mountains, which,
north of the Ecuador border, bifurcate into three ranges, the Western, Central
and Eastern Cordillera, extending toward the Caribbean coast. These ranges are
separated by the Cauca and Magdalena valleys, respectively. To the east lies the
Llanos, a savanna within the bounds of the Orinoco Basin, which extends over the
remainder of the country.

       The geology of Colombia has been studied since the mid 1800's and has
continued to the present, amassing some detail of the tectonic framework and
related stratigraphy. During the evolution of the geological knowledge of
Colombia, oil and natural gas exploration has been pursued in the Llanos,
Putumayo and Magdalena basins. Exploration in the Upper Magdalena 

                                    - 11 -
<PAGE>
Valley Basin began in 1918 with the drilling of the Guataqui wells in the
Girardot subbasin, followed in 1951 by the Ortega discovery. As of December
1993, 210 exploratory wells had been drilled, resulting in the discovery of 30
fields.

       This page consists of a map outlining the state of Colombia, South
America and portions of the bordering states of Venezuela, Brazil, Peru and
Ecuador. The Company's Dindal and Rio Seco Blocks and the Tapir Block are shown
in yellow; producing oil fields are indicated by green ovals and the Cusiana,
Cano Limon-Guafita and Shushufindi oil fields are also identified by name; oil
pipelines are indicated by green lines, including outlets to the Pacific Ocean
and Caribbean Sea. The map references distance measurements in kilometers and
miles.

       This page consists of a color map entitled: "Cimarrona Depth Structure
Map" and shows the Dindal and Rio Seco Blocks with a small insert in the upper
left hand corner showing the location of the blocks and Bogota on a small map of
Colombia. The map references distance measurements in kilometers and miles, and
shows the depth in feet of certain areas. The map shows the location of the El
Segundo No. 1 and El Segundo No. 2 oil wells, the proposed appraisal location of
the Tres Pasos No. 1 well and additional proposed appraisal locations. The map
also shows the location of the following wells: Escuela No. 1, Madrigal No. 1,
Ocobo No. 1, Quina No. 1, Las Palmas No. 1, and Tomate No. 1, and additional
wells drilled in the area and, in each case, indicates by symbol whether such
well was a dry well with gas and oil shows, a dry well with gas shows, or a dry
well with oil shows. The map also indicates the existence of oil seeps,
Cimarrona outcrop, the potential oil field area and the location of the Guaduas
Fault.

                                     - 13 -

       The Company's principal asset is a 57.7% interest in the Association
Contracts with Empresa Colombiana de Petroleos, the Colombian national oil
company ("Ecopetrol") which entitle the Company to engage in exploration,
development and production activities in approximately 106,000 acres located in
the oil producing Upper Magdalena Basin, about 90 kilometers northwest of
Bogota. The area is accessible via the main road between Bogota and Honda. The
village of Guaduas lies within the block and provides infrastructure for the
local economy which is primarily agrarian in nature.

       Recent discoveries in the Magdalena Basin include Amoco's Opon Field,
located approximately 170 kilometers north of the prospect area, and Lasmo's
Venganza/Revancha complex, located approximately 150 kilometers to the south.
The main Rio Magdalena oil pipelines (12" to 20" diameters) lie approximately 20
kilometers west of the prospect area and provide an opportunity for oil
transportation from the Company's discovery. Early production from the discovery
well and subsequent wells in Dindal and Rio Seco blocks will likely be truck
transported by road to an oil terminal on the Rio Magdalena pipeline system
approximately 78 miles away, prior to full field development and pipeline
installation.

       PROSPECT GEOLOGY. The Dindal structure is formed by a faulted anticlinal
closure in the foot wall of the Bituima thrust fault system on the eastern side
of the Rio Magdalena river valley. The primary oil reservoir is the Upper
Cretaceous Cimarrona formation which is comprised of both limestones and
sandstones in the vicinity of the Dindal structure. These reservoir sequences
are charged with oil generated from the immediately underlying Villeta shale
which is considered the principal source rock for the oil accumulations
throughout Colombia and Venezuela. The Villeta shale is present in area wells
both in and adjacent to the Dindal block.

       The Cimarrona formation is seen in surface outcrop to the north and west
of the structure, as well as in the Lasmo Madrigal #1 well, the AIPC Quina #1
well and the GHK El Segundo #1 and #2 wells. From this geologic control
information, the Cimarrona is shown to be depositionally complex, exhibiting
rapid changes in both gross thickness and rock types in the region of the Dindal
structure. In the Madrigal #1 well, the Cimarrona is approximately 1,600 feet
thick with mixed rock types including sandstones, conglomerates, siltstones and
shales. Only 9 kilometers east in the El Segundo #2 well, the Cimarrona has
thinned to approximately 450 feet in thickness and contains limestones,
calcareous sandstones, and siltstones. Additional data from appraisal wells
concerning these variations is required before oil reserves can be reliably
assessed for the structure and an appropriate field development plan drafted.

       Evidence for the anticlinal trap at the structure is found in both
seismic data over the prospect and in surface geologic mapping. The trapping
mechanism is believed to be formed by structural closure in three directions
(north, south and west), and an imbricate fault within the Bituima Fault system
to the east, which is evidenced in the Escuela #1 well which was drilled in
1994, prior to the acquisition of an interest in the block by the Company, and
was plugged and abandoned as a dry hole. The Escuela #1 well is located four
kilometers southeast of the El Segundo #1 well location and encountered Tertiary
and Cretaceous shales and siltstones from surface to total depth. This
predominantly shale section, emplaced by thrust faulting adjacent to the
Cimarrona reservoir section, is believed to form the critical element of the
trap for the prospect.

       EXPLORATION ACTIVITY. The El Segundo #1 discovery well commenced drilling
in December 1995 and reached total depth in mid-January, 1996. The well reached
the objective Cimarrona formation at a depth of 5,630 feet, but stopped drilling
after penetrating only 88 feet of the Cimarrona due to circulation problems
encountered while drilling. The well was then completed for testing in February
1996 and drill stem tests recovered 19(degree) API oil at surface limited rates
of 300-500 barrels per day. Operations were then suspended pending receipt of a
permit to transport produced oil by truck from a long-term production test.
Permits for the long-term production test were received in late June 1996 and
production testing commenced in early July. Tests using electric submersible
pumps produced oil at rates of 3,400 barrels per day. No aquifer water was
produced during the tests, and analysis of reservoir pressure response during
testing and the shut-in period following testing showed no evidence of reservoir
boundaries, geologic complexities or oil-water contact. Analysis of oil
recovered during testing showed 19(degree) API gravity, low sulphur crude oil,
with reservoir temperature of 120(degree)F, pressure of 1,640 psi and bubble
point of 1,570 psi (at collection datum). Following testing during August, El
Segundo #1 was shut-in to allow drilling of the El Segundo #2 well from the same
surface location.

       The El Segundo #2 well commenced drilling in early September 1996 and
reached total drilling depth of 6,820 feet in late October. The well was
intentionally deviated from the surface location of the EL SEGUNDO #1 well to a
bottom hole location some 2,000 feet north of the surface location. The well
encountered approximately 450 feet of oil saturated and highly fractured Upper
Cretaceous Cimarrona formation at a drilling depth of 6,052 feet (vertical depth
of 5,588 feet). The well was completed for testing in November, and five drill
stem tests were conducted in late November through February. The first two tests
in the upper Villeta formation and the lower Cimarrona formation recovered no
oil and have been interpreted to be low permeability. The last three tests,
conducted in separate intervals of the upper Cimarrona between 6,052 and 6,280
feet, produced oil at rates from 3,866 to 6,154 barrels per day each. Following
these tests in February 1997, production tests were conducted of the combined
interval between 6,052 and 6,315 feet. These tests produced oil at rates as high
as 8,948 barrels per day. Analysis of reservoir pressure performance during and
following the production testing in El Segundo #2 well supported the conclusions
from the production testing of the El Segundo #1 well in July and August 1996.
In March, 1997 the El Segundo #2 well was placed on long-term production test to
gather further reservoir information.

       The first well for the Rio Seco Association Contract, the Tres Pasos #1
well, is expected to commence drilling operations in May 1997. The Tres Pasos #1
well is an appraisal well for the oil accumulation discovered in the Dindal
block and is located some 2.5 kilometers northwest of the surface location of
the El Segundo #1 and #2 wells. The Company plans to drill up to two additional
wells on the Dindal block in 1997 and to acquire permits for a seismic survey to
further delineate the areal extent and reservoir geology of the structure.

       The Company and its partners have paid all costs of the exploration
program under the Association Contracts to date. Under the terms of the
Association Contract, the Company and its partners are required to drill one
well on each contract per year and will continue to bear all exploration costs
relating to a field until such field is declared commercial. The Company plans
to submit a commerciality application to Ecopetrol during the fourth quarter of
1997 or the first quarter of 1998 with respect to its first discovery.

       GHK Company Colombia, an indirect wholly-owned subsidiary of the Company,
serves as the operator of the joint venture to develop the Dindal and Rio Seco
blocks, pursuant to the terms of operating agreements between the Company, its
respective subsidiaries and its joint venture partners. GHK Company Colombia has
exclusive charge of carrying out the program of operations within the budgets
approved by the operating committee and may demand payment in advance from each
party of its respective shares of estimated monthly expenditures. GHK Company
Colombia has retained GHK Company L.L.C., the principal owner of which is Robert
A. Hefner, III, a director of the Company, to perform the duties and obligations
of GHK Company Colombia under the Association Contracts and as operator of the
Dindal and Rio Seco blocks pursuant to the terms of a Management Agreement more
particularly described under "Certain Relationships and Related Transactions -
The GHK Transaction."

       TERMS OF ASSOCIATION CONTRACTS AND RELATED MATTERS. The Association
Contracts were issued by Ecopetrol in March 1993 and August 1995, respectively,
and provide generally for a six year exploration phase followed by a twenty-two
year production period, with partial relinquishments of acreage, excluding
commercial fields, required commencing at the end of the sixth year of each
contract. Under the terms of the Association Contracts, Ecopetrol will receive a
royalty equal to 20% of production (after pipeline tariffs are deducted) on
behalf of the Colombian government and, in the event a commercially feasible
discovery is made, Ecopetrol will acquire a 50% interest in the remaining
production, bear 50% of the development costs, and reimburse the joint venture,
from Ecopetrol's share of future production, for 50% of the joint venture's
costs of certain exploration activities. Upon acceptance of a field as
commercial, Ecopetrol will acquire a 50% interest therein and the interests of
the other parties to the contract, including the Company, will be reduced by
50%; all decisions regarding the development of a commercial field will be made
by an Executive Committee consisting of representatives of the parties to the
contract who will vote in proportion to their respective interests in such
contract. Decisions of the Executive Committee will be made by the affirmative
vote of the holders of over 50% of the interests in the contract.

       If any commercial field in the respective contract areas produces in
excess of 60 million barrels, Ecopetrol's interest in production and costs for
such contract area increases as follows: (i) under the terms of the Dindal
Association Contract, such increases occur in 5% increments from 50% to 70% as
accumulated production from any field increases in 30 million barrel increments
from 60 million barrels to 150 million barrels; and (ii) under the terms of the
Rio Seco Association Contract, Ecopetrol's interest increases from 50% to 75% as
the ratio of the accumulated income attributable to the parties to the contract
other than Ecopetrol to the accumulated development, exploration and operating
costs of such parties (less any expenses reimbursed by Ecopetrol) increases from
one to one to two to one.

       Under the terms of the Association Contracts, in the event a discovery is
made and is not deemed to be commercially feasible, the joint venture may expend
up to $2 million over a one year period to further develop the field, 50% of
which will be reimbursed if Ecopetrol subsequently accepts the commercial
feasibility thereof. If Ecopetrol does not declare the field commercial, the
joint venture may continue to develop the field at its own expense. In such
event, Ecopetrol will have the right to acquire a 50% interest therein upon
payment of 200% of the amounts expended by the joint venture, which payment may
be made out of Ecopetrol's share of future production.

       Oil produced from the Dindal block to date under the long term production
tests has been sold to Ecopetrol. Upon Ecopetrol's declaration of the
commerciality of the Company's discovery, oil produced from the Dindal and Rio
Seco blocks may be sold to Ecopetrol or to third parties provided that 75% of
the purchase price is paid in U.S. dollars and the remainder in Colombian pesos.
In the event the production is required to satisfy internal demand for oil in
Colombia, the Company may be required to sell some or all of its production to
Ecopetrol at prevailing market prices.

      The Company's net income, as defined under Colombian law, from Colombian
sources is subject to Colombian corporate income tax at a rate of 35%. An
additional remittance tax is imposed upon the remittance of profits abroad at a
rate of 7%.

       ACQUISITION OF INTEREST. Pursuant to an agreement dated August 14, 1995,
as amended, the Company acquired from GHK Company Colombia, a 15% interest in
the Association Contracts in consideration of the payment of $100,000 and its
share of the cost of drilling, testing and completing the El Segundo #1 well and
its proportionate share of the obligations for the first year of the Rio Seco
Association Contract. The Company acquired an additional 36.7% interest in the
Association Contracts indirectly through its acquisition of 100% of the
outstanding securities of GHK Company Colombia and Esmeralda Limited Liability
Company and its acquisition of 62.963% of the outstanding securities of
Cimarrona Limited Liability Company. For a more particular description of these
transactions, see "Certain Transactions."

       The Company acquired a 6% interest in the Association Contracts
indirectly through its acquisition of 100% of the outstanding securities of
Petrolinson S.A. (Petrolinson"), the holder of such 6% interest, in
consideration of the issuance of 1,000,000 Common Shares to the shareholder of
Petrolinson, of which 995,000 shares are held in escrow until July 1997. As the
holders of the remaining 94% interest in the Association Contracts, including
the Company, had previously agreed to pay 100% of the exploration costs
attributable to such 6% interest through the exploration period, approximately
45% of the exploration costs for the Association Contracts attributable to the
6% interest acquired by the Company are paid by the other holders of interests
in the Association Contracts. The exploration period will terminate upon
Ecopetrol's declaration of the commerciality of a field.

       Under the terms of a letter agreement dated September 11, 1992, as
amended, between GHK Company Colombia and Dr. Jay Namson, the holders of
interests in the Association Contracts, as a group, will be required to assign a
2% working interest in the Dindal Association Contract and the Rio Seco
Association Contract to Dr. Namson after recovery from production of 100% of all
costs incurred in connection with the exploration and development of the Dindal
and Rio Seco blocks since the completion of the first year work obligations
under the Dindal Association Contract. Accordingly, when such costs have been
recovered, the Company will be required to assign to Dr. Namson 2% of its
interests (or a 0.577% interest in each Association Contract, after adjusting
for the acquisition of a 50% interest by Ecopetrol which is expected to occur
prior to the assignment to Dr. Namson).

TAPIR ASSOCIATION CONTRACT, LLANOS BASIN

       INTRODUCTION. The Company acquired an 11.875% interest in the Tapir
Association Contract (the "Tapir Association Contract") in April 1996. The Tapir
block consists of 250,000 acres located in the Llanos Basin of east central
Colombia and is crossed by two oil pipelines carrying production from nearby oil
fields. Other Tapir Association Contract interests are held by Ampolex (56.25%),
Mohave Oil & Gas Corp. ("Mohave") (10.205%), Doreal Energy (11.67%) and Heritage
Minerals Colombia ("Heritage Minerals") (10%), which serves as the operator.

       EXPLORATION PROSPECTS. There are three exploration prospect types on the
Tapir block: several conventional Llanos Basin small structural closures, a deep
Paleozoic anomaly and two basal Cretaceous stratigraphic prospects. The small
structural closures are relatively low risk, but are expected to have low
reserves potential (10-30 MMBO each). The Paleozoic prospect is of geologic
interest, but relies on unproven source and reservoir rocks, and is therefore
high risk until further geologic work can be completed. The geologic risk for
the two Cretaceous stratigraphic prospects depends on the effectiveness of the
lateral seal between the Ubaque sandstone and the adjacent Paleozoic section.

       The Mateguafa prospect, one of the small structural closures in the
central portion of the Tapir block, has been selected as the first exploration
drill site in the Tapir block and is expected to commence drilling in late 1997
or the first quarter of 1998, following receipt of required permits from the
Ministry of Environment.

       EXISTING WELL. In 1993, the Macarenas #1 well, a discovery well, was
drilled on the Tapir block and produced 320 BOPD in a short-term test, but was
not completed for production. Since the well was drilled and tested, additional
oil pipeline infrastructure has been built in the area. The operator plans to
place the well on long-term production test after the completion of the
exploratory well to determine sustainable production rates and the extent of the
reservoir.

       TERMS OF TAPIR CONTRACT. The Tapir Association Contract was effective on
February 6, 1995 on terms substantially similar to the Rio Seco Association
Contract. Heritage Minerals, the Tapir Association Contract operator, has
completed an 83 kilometer seismic program in the field, which satisfied the work
program for the first year of the Tapir Association Contract and part of the
second year. The commitment for the second year well has been extended and the
exploration well required in the second year work program is expected to
commence drilling in late 1997 or the first quarter of 1998.

       The Company acquired its interest in the Tapir Association Contract in
April 1996 in consideration of the payment for $104,000 which represents
reimbursement for past seismic costs and permit administration, and its
agreement to pay its proportionate share of the costs of a seismic program, the
first exploratory well, the long-term production test on the Macarenas #1 well
(assuming the parties elect to proceed therewith) and certain additional costs
to earn its interest in the Tapir Contract. The Company estimates that its
proportionate share of these costs, which are required to be paid to retain its
interest in the Tapir Association Contract, is approximately $300,000.

AUSTRALIA

PERTH BASIN, EP381 AND WHICHER RANGE PERMITS.

       The Company holds an 11.77% working interest in Exploration Permit 381
and the Whicher Range Permit Application (which has been conditionally granted
but not yet issued), both of which are located in the southern Perth Basin,
Western Australia. Other interests in these permit areas are held by: Pennzoil
(44.115%), Amity Oil (30.115%) and GeoPetro Company (14%).

       The EP 381 Permit covers an area of 455,405 acres; the Whicher Range
Permit Application covers 439,141 acres and adjoins the EP 381 Permit to the
north for a total area of 894,546 acres. The Whicher Range Permit Application
has been reserved for the applicants pending resolution of native claims
pursuant to the Australian NATIVE CLAIMS ACT 1993.

       The greater Perth Basin produces gas and oil from accumulations onshore
in a region north of the Company's permit areas and north of the city of Perth.
The area in and around the Company's permit areas is the site of farming and
mining activities which has created an apparent strong local demand for energy
which would be the intended market for any natural gas produced from the EP 381
or the Whicher Range Permits.

       The principal exploration interest in the EP 381 and the Whicher Range
Permit areas is for natural gas generated in Permian coal measures and
reservoired within adjacent Permian sandstones. The operator of the permit areas
has conducted reservoir studies on the Whicher Range Permit Application area,
which contains the Whicher Range Gas Field discovered by Union Oil of California
in 1968. The results of these studies indicate that the use of different
drilling technologies and newer completion techniques could make the Whicher
Range Gas Field economic to develop. Based on this technical assessment and the
market for natural gas now believed to be available in the area, the partners
plan to re-enter and test the Whicher Range #1 well in 1997. If this re-entry
and test is successful, the parties may drill an additional well in late 1997
and initiate additional seismic programs in the block. In addition, a new
seismic study was commenced in March 1997 to delineate further prospects in the
EP 381 prospect area. In May 1995, the Scott River #1 well was drilled in the
southern portion of EP 381, encountered Permian sandstones which had
sub-commercial saturations of natural gas and was abandoned.

       The Company acquired its interest in EP381 and the Whicher Range Permit
Application by virtue of a farm-in agreement dated March 6, 1995 and an
additional assignment of an interest in 1996. The parties to EP 381 have
complied with the work commitments required under EP 381 through the end of the
current contract year; the parties to the Whicher Range Permit Application
believe that the planned re-entry in the Whicher Range #1 well will satisfy the
work commitment at least through the first year of such permit.

BASS BASIN, BLOCK T27P.

       The Company holds a 20% working interest in Block T27P, a 1.8 million
acre block in approximately 70 meters of water, in the Bass Basin, the central
of three basins offshore southern Australia. The easternmost basin is the
Gippsland Basin where BHP Petroleum and Esso have a series of large oil and gas
fields. The westernmost basin is the Otway Basin, the 

                                     - 19 -
<PAGE>
site of recent gas discoveries by BHP Petroleum and others which will likely
serve the South Australia and Victoria gas market. The T27P block lies about
halfway between the Victoria coast to the north and the Tasmania coast to the
south (about 90 kilometers each way). The Bass Basin has been the site of a
series of gas and oil shows and discoveries, including the Yolla Field, which is
adjacent to Block T27P. The Yolla Field was discovered by Amoco in the
mid-1980's and has not yet been appraised or developed.

       Globex Exploration, the operator of the permit with an 80% working
interest, was granted the Offshore Petroleum Exploration Permit effective August
10, 1994 (the "Bass Basin Permit"). Globex completed a 1,000 kilometer 2D
seismic program in the block. The remaining work commitment in the block
consists of a 3D seismic survey and two exploration wells. Globex has selected a
drillable prospect some 10 kilometers north of the Yolla Field and is seeking
additional participants in the block to share the cost of an exploratory well
which is estimated to be approximately $5 million. As suitable drilling rigs are
not available in the near term, Globex has applied for a permit extension in the
block until a suitable rig can be contracted.

       In March 1996, the Company acquired a six-month option to purchase its
interest in the block for $250,000 and exercised that option in September 1996.
Pursuant to the terms of the option agreement, the Company may elect to farmout
up to 50% of its interest in the Bass Basin Permit. In addition, if Globex
Exploration and the other interest holders seek to enter into a farmout, the
Company has agreed to participate proportionally with such parties in such
farmout provided that its interest may not be reduced below 10%.

PAPUA NEW GUINEA

PERMIT PPL-182

       The Company holds 100% of exploration permit PPL-182 in southern Papua
New Guinea effective June 11, 1996. The permit covers an area of 1,200,000 acres
located both onshore and offshore in the Fly River Delta and the Gulf of Papua.

       The nearest discovery to the permit area is the Pandora Gas Discovery
located in PPL-82 approximately 150 kilometers to the east in the Gulf of Papua.
The International Petroleum Corporation and Chevron announced in March 1996 a
feasibility study for the delivery of gas from the Pandora Gas Field and from
other fields in Papua New Guinea to be transported south to northern Australia.

       Past exploration activity within PPL-182 has resulted in the acquisition
of seismic data and the drilling of several exploration wells. The Company's
first year work program consists of a geological and geophysical review of
existing data. Based on the results of this study, the Company will decide
whether to proceed with the second year's work commitment which provides for
seismic reprocessing and acquisition of a high resolution aeromagnetic survey
and is expected to cost approximately $500,000. At the end of the second year
work program, the Company will decide whether to continue its exploration
program or relinquish the permit. The Company plans to secure an industry
partner or partners to underwrite a significant portion of future exploration
costs.

OTHER PROPERTIES

       As a result of the Amalgamation, Seven Seas acquired three mineral
properties owned by Rusty Lake, two of which have been sold. The remaining
property, consisting of a 60% interest in two patented mining parcels located in
Whitney Township in the Province of Ontario, is being offered for sale. The
Company has no plans to explore these mining properties.

       Since its inception, the Company has been involved in exploration
activities in Colombia, Australia, Argentina, Turkey and Papua New Guinea.
Exploration activities in Argentina and Turkey have been discontinued and an
option for the right to participate in future exploration activities in North
Africa was never exercised.

VOTING SUPPORT AGREEMENTS

    Under the terms of a Voting Support Agreement executed in connection with
the GHK Transaction described below under "Certain Relationships and Related
Transactions," Seven Seas, Robert A. Hefner III, Breene M. Kerr, Albert E.
Whitehead, George H. Plewes, and Timothy T. Stephens agreed to vote or cause to
be voted all shares owned or controlled by them in favor of the slate of
directors proposed by the Company's chief executive officer. The Voting Support
Agreement also provides that a sale by Messrs. Hefner and Kerr of a block of
10,000 Common Shares or more which were initially subject to the GHK Escrow
Agreement, must first be offered to be made through Yorkton Securities Inc. or
such other investment dealer as may be designated by the Board of Directors or
the securities sold will remain subject to the Voting Support Agreement. In the
event any such dealer is unable or unwilling to sell such securities in a timely
manner at a price acceptable to the seller, the seller may sell to a third party
without being subject to the Voting Support Agreement provided that such sale is
not to a person or one or more of a group of persons acting in concert, who is
acquiring the securities of the seller in connection with a takeover bid, other
than where such takeover bid is an offer made generally to the shareholders of
the Company. The Voting Support Agreement will terminate on the earlier to occur
of July 19, 1998, the date either Messrs. Egolf and Hefner are not elected as
directors; the date two of Messrs. Albert E. Whitehead, George H. Plewes and
Timothy T. Stephens are not elected as directors or cease to be officers of the
Company; if, during any six month period, the Company issues in excess 

                                     - 24 -
<PAGE>
of 25% of the then issued and outstanding shares of the Company at the beginning
of such period, without obtaining shareholder approval; or the failure of the
Company to maintain directors' and officers' insurance.

    Under the terms of a voting support agreement by and between the Company and
Hazel Ventures Ltd., the sole shareholder of Petrolinson ("Hazel Ventures"),
Hazel Ventures agreed that prior to July 19, 1998, it will vote all Common
Shares of the Company owned or controlled by it in favor of the slate of
directors proposed by the Company's chief executive officer and will require any
purchaser of its shares to agree to be bound by the terms of the agreement
unless the purchaser acquires the shares in the open market. Hazel acquired
1,000,000 Common Shares, or 2.9% of the Company's outstanding Common Shares, in
exchange for the transfer of its ownership of Petrolinson, the holder of a 6%
interest in the Association Contracts, to a subsidiary of the Company.

MEETINGS AND COMMITTEES OF THE BOARD

      The Board of Directors of the Company held three meetings during 1996 and
took action by unanimous written consent twenty times during 1996. All directors
attended 75% or more of the total number of meetings of the Board and of the
committees of which they were members.

      The Executive Committee, the Audit Committee and the Stock Option and
Compensation Committee (the "Compensation Committee") are the only standing
committees of the Board. There is no formal nominating committee; the Board of
Directors or the Executive Committee performs this function.

      The Executive Committee, which is currently composed of Messrs. Whitehead,
Stephens, and Hefner, has all the powers of the Board of Directors in the
management of the business and affairs of the Company, except as such powers are
limited by the Yukon Business Corporations Act. During 1996, the Executive
Committee met one time.

                                     - 27 -
<PAGE>
      The Audit Committee, which is currently composed of Messrs. McIntosh and
Zaozirny, consults with the auditors of the Company and such other persons as
the members deem appropriate, reviews the preparations for and scope of the
audit of the Company's annual financial statements, makes recommendations
concerning the engagement and fees of the independent auditors, and performs
such other duties relating to the financial statements of the Company as the
Board of Directors may assign from time to time. The Audit Committee met two
times during 1996 and took action by unanimous consent twice during 1996.

      The Compensation Committee, which currently is composed of Messrs. Millard
and Robinson, has all of the powers of the Board of Directors, including the
authority to issue shares or other securities of the Company, in respect of any
matters relating to the administration of the Company's 1996 Stock Option Plan
and the compensation of officers, directors, employees and other persons
performing substantial services for the Company. The Compensation Committee took
action by unanimous written consent twice during 1996.

DIRECTORS' FEES

      Directors who are officers or employees of the Company receive no
additional compensation for their service as members of the Board of Directors
or as members of Board committees. Directors who are not officers or employees
of the Company are eligible to participate in the Company's Amended 1996 Stock
Option Plan and are reimbursed for their out-of-pocket expenses incurred in
connection with their service as directors, including travel expenses. In July
1996, each non-employee director received a five year option to purchase 10,000
Common Shares at an exercise price of $7.125 per share. In November 1996, upon
their election as directors, Messrs. Hefner and Egolf each received a five year
option to purchase 50,000 Common Shares at an exercise price of $18.75 per
share. In each case, the exercise price of the options was equal to the market
value for a Common Share on the date of grant.

EMPLOYMENT CONTRACTS AND CHANGE OF CONTROL ARRANGEMENTS

       The Company and each of Messrs. Stephens, Dorrier and DeCort have entered
into three year employment contracts which provide that they will receive annual
base salaries of $175,000, $150,000 and $112,500, respectively, and, in the sole
discretion of the Compensation Committee of the Board, may receive annual merit
increases, annual bonuses and stock option awards. The contracts may be
terminated for "cause" which includes death or serious incapacity and the
executive officers may resign upon three months' prior written notice.

      The Company and each of Messrs. Stephens, Dorrier and DeCort have also
entered into agreements which provide for payments to the executive in the event
there is a Change of Control of the Company and the executive's employment is
terminated (i) by the Company within twelve months thereafter, (ii) by the
executive within six months thereafter, or (iii) by the executive between six
and twelve months after a Change of Control if a Triggering Event has occurred.
In any such event, the executive shall be entitled to a payment equal to the
aggregate salary payable for the remaining term of his employment agreement and
the Company shall pay the executive's health insurance premium for a period of
one year unless the executive has secured comparable health insurance prior
thereto. If bonuses are paid by the Company for the year in which the
executive's employment terminated, the executive shall be entitled to a bonus
equal to the most recent annual bonus paid to him. In addition, all stock
options held by the executive shall be extended until the earlier to occur of
the expiration date of the option or eighteen months after the date of the
termination of his employment by the Company or the date of his notice of intent
to 

                                     - 31 -
<PAGE>
terminate his employment if he elected to resign. The agreements also provide
that in the event the exercise price of any option granted simultaneously with
the option issued to the executive is reduced, the exercise price of the
executive's option shall also be reduced. For purposes of the agreement, the
term "Change of Control" is defined to include the acquisition by any person or
combination of persons of a sufficient number of securities of the Company to
materially affect the control of the Company which, for purposes of the
agreement, shall be deemed to occur if 20% or more of the votes which may be
cast in the election of directors have been acquired by any person or
combination of persons; a merger, consolidation, or amalgamation with or into
any other person if all or part of the outstanding voting securities of the
Company shall be changed, reclassified, converted, exchanged or otherwise
acquired for shares or other securities of the Company or any other person or
for cash or any other property, unless such transaction has been approved by a
majority of the directors in office on April 28, 1997; a majority of the
directors in office on April 28, 1997 shall cease to serve as directors of the
Company for any reason including resignation; the sale or other transfer of
assets which constitute more than 50% of the consolidated assets of the Company
(measured by either book value or fair market value) or which generated more
than 50% of the consolidated operating income or cash flow of the Company. The
term "Triggering Event" shall include any adverse change in the duties, powers
or compensation of the executive in effect prior to the Change in Control or a
change in the person to whom the executive reports, other than as a result of a
promotion in the normal course of business.


ITEM 7. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

THE GHK TRANSACTION

      In April 1996, the Company and GHK Company Colombia, an Oklahoma
corporation controlled by Robert A. Hefner III, entered into a non-binding
letter of intent governing a proposed acquisition by the Company of an
additional 35% participating interest in the Association Contracts in
consideration of the issuance of up to 16,000,000 Common Shares by the Company
to three entities holding such interests or to their respective shareholders
(collectively, the "GHK Transaction"). Effective July 26, 1996, pursuant to the
terms of three separate share purchase agreements, the Company agreed to issue
an aggregate of 16,777,143 Common Shares to nineteen unrelated parties, in
consideration of the Company's acquisition of (a) 100% of the issued and
outstanding shares of GHK Company Colombia which serves as the operator under
the Association Contracts and holds a 10.944% interest in such contracts, (b)
100% of the membership interests of Esmeralda Limited Liability Company
("Esmeralda") which holds a 9.776% interest in the Association Contracts, and
(c) 62.963% membership interest in Cimarrona Limited Liability Company
("Cimarrona") which holds a 25.38% interest in the Association Contracts. As a
result of the transaction, the Company acquired an additional 36.7% indirect
interest in the Association Contracts. As a condition to the GHK Transaction,
the Company also entered into the Registration Rights Agreement, the Escrow
Agreement and the Management Agreement, each of which is more particularly
described below, and the Voting Support Agreement which is more particularly
described above under "Principal Stockholders."

      Pursuant to the terms of the share purchase agreement between the Company
and Robert A. Hefner III, the Company purchased 100% of the issued and
outstanding shares of GHK Company Colombia from Mr. Hefner in consideration for
the issuance of 5,002,972 Class A Preferred Shares Series 1 of the Company to
him. Pursuant to the terms of the share purchase agreement between the Company
and the members of Esmeralda, the Company purchased 100% of the membership
interests of Esmeralda from such members in consideration for the issuance of 

                                     - 32 -
<PAGE>
an aggregate of 4,469,028 B Special Warrants (the "B Warrants") to such members.
Pursuant to the terms of the share purchase agreement between the Company and
the members of Cimarrona, the Company purchased a 62.963% membership interest in
Cimarrona from such members in consideration for the issuance of an aggregate of
7,305,143 B Warrants to such members. The Preferred Shares and the B Warrants
were issued at a deemed price per share of $9.125 which was based upon the
closing price of the Company's Common Shares on the Canadian Dealer Network on
July 26, 1996. As a condition to each purchase agreement, the Company agreed
that two representatives of the sellers under such agreements would be appointed
to the Board of Directors of the Company and Messrs. Robert A. Hefner, III and
Brian Egolf are serving on the Board of Directors as their representatives. In
addition, Mr. Hefner and Breene M. Kerr entered into the Voting Support
Agreement, more particularly described above under "Principal Stockholders."

      Each B Warrant was exercisable into one Common Share without payment of
additional consideration and was automatically converted into a Common Share, in
accordance with the terms of the Company's Articles of Continuance, in February
1997. Each Preferred Share was entitled to one vote per share, was exercisable
into one Common Share without payment of additional consideration and was also
automatically converted into a Common Share, in accordance with the terms of the
Company's Articles of Continuance, in February 1997. As the Preferred Shares
were issued to Mr. Hefner in lieu of B Warrants to enable him to effect the sale
of the shares of GHK Company Colombia on a tax-free basis, Mr. Hefner agreed to
indemnify the Company from any tax liability to which the Company became subject
as a result of the transaction.

      The shares of GHK Company Colombia and the 62.963% interest in Cimarrona
were transferred to Seven Seas Petroleum Colombia Inc.; 50% of the membership
interest in Esmeralda was transferred to Seven Seas Petroleum Colombia Inc.; and
50% of such membership interest was transferred to Seven Seas Petroleum
Holdings, Inc. as a limited liability company is required to have a minimum of
two members.

      As a condition of completing the GHK Transaction, the Company also entered
into a Registration Rights Agreement with the holders of the B Warrants and the
Preferred Shares which currently entitles such holders to notice of proposed
public offerings or private placements by the Company under the Securities Act
(Ontario) and to include Common Shares held by such holders in such offerings
subject to limitations which may be imposed by the managing underwriter of any
such offering. The Registration Rights Agreement will terminate on the earlier
to occur of July 26, 1998 or the termination of the Voting Support Agreement.

      As a condition of the Company obtaining the consent of the Ontario
Securities Commission to the GHK Transaction, the Company, the holders of
Preferred Shares and B Warrants and the Montreal Trust Company of Canada, as
trustee, entered into an escrow agreement dated July 26, 1996 (the "GHK Escrow
Agreement") pursuant to which 70% of the securities issued by the Company in the
GHK Transaction, or upon conversion or the securities issued therein, are held
in escrow. An aggregate of 11,744,000 Common Shares are currently held in escrow
and such Common Shares may not be sold, assigned, pledged, or transferred until
released from escrow in accordance with the terms of the GHK Escrow Agreement.
Shares held in escrow may be voted by the registered holders thereof. Pursuant
to the terms of the Escrow Agreement, the securities held in escrow shall be
released as follows: (i) one-third of the securities deposited in escrow shall
be released on each of July 26, 1997, 1998 and 1999 or (ii) the securities may
be released in full if the Company or the owner of such securities provides the
Ontario Securities Commission with technical reports acceptable to the director
thereof that establish a determinate value as of April 26, 1996 for the
interests in the Association Contracts transferred to the Company or its

                                     - 33 -
<PAGE>
subsidiaries, of $118,908,000 or more. If interim technical reports establish a
determinate value of less than $118,908,000 for such interests, proportionate
releases from escrow may be permitted.

      Prior to the GHK Transaction, GHK Company L.L.C. ("GHK L.L.C."), an
Oklahoma limited liability company, the principal owner of which is Robert A.
Hefner, III, provided administrative and management services to GHK Company
Colombia in connection with its obligations as operator of the Dindal and Rio
Seco blocks. As a condition of completing the GHK Transaction, the Company, GHK
Company Colombia and GHK L.L.C. entered into a Management Agreement pursuant to
which GHK L.L.C. was retained by GHK Company Colombia to perform the duties and
obligations of GHK Company Colombia under the Association Contracts and as
operator of the Dindal blocks under the joint operating agreement dated August
1, 1996 (the "JOA"). GHK Company Colombia agreed to pay GHK L.L.C. a monthly sum
equal to 100% of the overhead charges authorized under the JOA relating to such
blocks (which costs are estimated to be approximately $15,000 per month) plus an
additional $15,000 per month and to reimburse GHK L.L.C. for all expenses
incurred in the performance of its duties under the Management Agreement. The
costs and expenses under the JOA are paid by the interest holders under the
Association Contracts proportionately to their percentage interests therein.
From July 26, 1996 to December 31, 1996, GHK Company Colombia paid an aggregate
of $144,305 to GHK L.L.C. for services provided under this agreement. The
Management Agreement may be terminated by either party upon 180 days prior
written notice and will terminate upon the earlier to occur of (i) the drilling
and completion of both the second year well under the Rio Seco Association
Contract and the fourth year well under the Dindal Association Contract, or (b)
the declaration of a commercial field under either of the Association Contracts,
by Ecopetrol.

      Prior to the GHK Transaction, neither Mr. Hefner, Mr. Egolf nor Mr. Kerr
were affiliated with the Company. As a result of the GHK Transaction, Messrs.
Hefner and Egolf were elected directors of the Company and Mr. Hefner and Mr.
Kerr became substantial shareholders of the Company. In addition, as a result of
an agreement between Mr. Hefner, in his capacity as the selling shareholder of
GHK Company Colombia, the members of Esmeralda and Cimarrona and Mr. Egolf
(collectively, the Sellers"), the Sellers paid Mr. Egolf an aggregate of 83,886
B Warrants, which were subsequently converted into 83,886 Common Shares, as
consideration for his services to the Sellers in connection with the GHK
Transaction.

      TRANSACTIONS WITH PROMOTER. Mr. Albert E. Whitehead, Chairman and Chief
Executive Officer of the Company and a director, may be deemed a promotor of the
Company. In connection with the formation of the Predecessor of the Company in
February 1995, Mr. Whitehead received 1,000,000 Common Shares for a total
consideration of $1.00. As of condition of the Common Shares being listed on the
Toronto Stock Exchange ("TSE"), the TSE required Mr. Whitehead to place 500,000
Common Shares held by him in escrow in accordance with the TSE's founder stock
policy. Under the terms of the escrow agreement (the "Founder's Escrow
Agreement") between Mr. Whitehead, the Company and Montreal Trust Company of
Canada as escrow agent dated January 21, 1997, one-third of the shares subject
thereto were to be released from escrow on each of June 29, 1996, 1997 and 1998
and, accordingly, 333,333 Common Shares are currently subject to the Founder's
Escrow Agreement. For a description of the Common Shares and options held by Mr.
Whitehead, see "Principal Stockholders" and "Executive Compensation."

ITEM 8.  LEGAL PROCEEDINGS.

      There are no material legal proceedings to which the Company is a party or
to which any of its property is subject.

ITEM 10.  RECENT SALES OF UNREGISTERED SECURITIES.

      Within the last three years, the Company issued the following securities
which were not registered under the Securities Act of 1933, as amended (the
"Securities Act"):

      On June 30, 1995, upon the Amalgamation, 11,999,999 Common Shares of the
Company were issued to the holders of the common shares of the Predecessor and
680,464 Common Shares of the Company were issued to the holders of shares of
Rusty Lake. The Amalgamation was conducted in Canada, was effected in accordance
with the laws of British Columbia and approved by the Supreme Court of British
Columbia.

      In March 1996, 2,000,000 Special Warrants were issued at a purchase price
of $2.75 per Unit pursuant to a brokered private offering of units conducted in
Canada pursuant to the British Columbia securities laws. The Units were
convertible into one common share and one half of one Class A share purchase
warrant (the "Class A Warrants"). Each whole Class A Warrant entitled the holder
thereof to acquire one additional Common Share at a price of $3.50 per share at
any time on or before March 14, 1997. Yorkton Securities Inc., First Marathon
Securities Limited and Griffiths McBurney & Partners Inc. served as agents for
the private placement and received a 7% commission on the gross proceeds
thereof. To the extent U.S. residents were involved in this transaction, the
Company believes that the issuance of securities was exempt from registration
under the Securities Act by virtue of the provision of Section 4(2) thereof.

      In July 1996, the Company issued the following securities in the GHK
Transaction: (i) an aggregate of 7,305,143 B Special Warrants to certain members
of Cimarrona Limited Liability Company as consideration for the transfer of a
62.963% membership interest in Cimarrona Limited Liability Company by such
members to a subsidiary of the Company,; (ii) 4,469,028 B Special Warrants to
the members of Esmeralda Limited Liability Company as consideration for the
transfer of a 100% membership interest in Esmeralda by such members to a
subsidiary of the Company, and (iii) 5,002,972 Class A Preferred Shares to
Robert A. Hefner III as consideration for the transfer of all of the issued and
outstanding shares of GHK Company Colombia to a subsidiary of the Company. The B
Special Warrants and the Class A Preferred Shares were each issued at a deemed
purchase price of $9.125 per Special Warrant and per Preferred Share. Each B
Special Warrant and each Class A Preferred Share was convertible in each case
into one Common Share of the Company. To the extent U.S. residents were involved
in this transaction, the Company believes that the issuance of securities was
exempt from registration under the Securities Act by virtue of the provision of
Section 4(2) thereof.

      In October 1996, 500,000 C Special Warrants were issued at a purchase
price of $15.00 per Unit pursuant to a brokered private offering of Units
conducted in Canada pursuant to the British Columbia securities laws. The Units
were convertible into one common share and one half of one Class B share
purchase warrant (the "Class B Warrants"). Each whole Class B Warrant entitles
the holder thereof to acquire one additional Common Share at a price of $18.50
per share at any time on or before October 15, 1997. Yorkton Securities and
Tuscarora Capital, Inc. jointly served as the agent for the private placement
and jointly received a 6% commission on the gross proceeds thereof. To the
extent U.S. residents were involved in this transaction, the Company believes
that the issuance of securities was exempt from registration under the
Securities Act by virtue of the provisions of Section 4(2) thereof.

                                     - 36 -
<PAGE>
      In February 1997, 19,277,143 Common Shares were issued upon the automatic
conversion of (i) the Special Warrants issued in March 1996, (ii) the B Special
Warrants and the Class A Preferred Shares issued in July 1996, and (iii) the C
Special Warrants issued in October 1996. As the conversion of such securities
was automatic, to the extent U.S. residents were involved in such transaction,
the Company relied on the exemption from registration under the Securities Act
by virtue of the provisions of Section 3(a)(9) thereof, since the securities
issued were exchanged by the Company with existing security holders exclusively
and no commission or other remuneration was paid or given directly or indirectly
for soliciting such exchange.

      In February 1997, 1,000,000 Common Shares were issued in a private
transaction to Hazel Ventures Ltd., a British Virgin Islands company, in
consideration of the transfer of 100% of the capital stock of Petrolinson S.A.
to a subsidiary of the Company in a transaction conducted outside of the United
States.

      From February 1996 through March 1997, an aggregate of 690,333 Common
Shares were issued to directors and employees of the Company upon the exercise
of employee stock options at purchase prices of $0.75 to $7.125 per share. To
the extent U.S. residents were involved in these transactions, the Company
believes that the issuance of securities was exempt from registration under the
Securities Act by virtue of the provisions of Section 4(2) thereof.

      In March 1997, 1,000,000 Common Shares were issued upon exercise of the
Class A Warrants at an exercise price of $3.50 per share. To the extent U.S.
residents were involved in this transaction, the Company believes that the
issuance of securities was exempt from registration under the Securities Act by
virtue of the provisions of Section 4(2) thereof.

ITEM 11.  DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED.

      The following statements are subject to the detailed provisions of the
Company's Articles of Continuance and By-Laws, do not purport to be complete,
and are qualified in their entirety by reference thereto.

    The Company's Articles of Continuance authorizes the issuance of an
unlimited number of Common Shares without par value and an unlimited number of
Class A Preferred Shares, without par value. As of April 24, 1997, 34,699,575
Common Shares, are issued and outstanding. As of April 29, 1997, the Company had
6,727 shareholders of record.

COMMON SHARES

    No holder of Common Shares has any preemptive right to subscribe for any of
the Company's securities. All outstanding shares are fully paid and
nonassessable. Holders of Common Shares are not entitled to cumulative voting
and are entitled to one vote per share with respect to all matters that are
required by law to be submitted to shareholders, including the election of
directors.

    Subject to the prior rights of the holders of any Preferred Shares that may
be outstanding, holders of Common Shares are entitled to share pro rata in such
dividends as may be declared by the Board of Directors out of funds legally
available for that purpose. In the event of liquidation of the Company, all
assets available for distribution (after satisfaction of the prior rights of the
holders of any outstanding Preferred Shares) are distributable among the holders
of the Common Shares according to their respective holdings.

                                     - 37 -
<PAGE>
    Montreal Trust Company of Canada, Suite 600, 530-8th Avenue, S.W., Calgary,
Alberta T2P 3S8, is the transfer agent and the registrar for the Company's
Common Shares.

    The authorized but unissued Common Shares and Preferred Shares could be used
to dilute the share ownership of persons seeking to obtain control of the
Company, and thereby defeat a possible takeover attempt which, if shareholders
were offered a premium over the market value of their shares, might be viewed as
being beneficial to the Company's shareholders. In addition, the Preferred
Shares could be issued with voting, conversion rights and preferences which
would adversely affect the voting power and other rights of holders of Common
Shares.

PREFERRED SHARES

    The Company's Articles of Continuance provide that the Board of Directors,
without shareholder approval, has the authority to issue Preferred Shares from
time to time in series and to fix the designation, powers (including voting
powers, if any), preferences and relative, participating, optional, conversion
and other special rights, and the qualifications, limitations, and restrictions
of each series, except that with respect to the payment of dividends and the
distribution of assets upon liquidation, each series shall rank equally with any
other series of Preferred Shares outstanding.

    In the event of issuance, the Preferred Shares could be utilized, under
certain circumstances, as a method of discouraging, delaying or preventing a
change in control of the Company. Such actions could have the effect of
discouraging bids for the Company, thereby preventing shareholders from
receiving the maximum value for their shares. Although the Company has no
present intention to issue any additional Preferred Shares, there can be no
assurance that the Company will not do so in the future.

CANADIAN FEDERAL INCOME TAX CONSIDERATIONS.

    The following is a summary of the principal Canadian income tax
considerations generally applicable to nonresidents of Canada who hold the
Common Shares as capital property, deal at arm's length with the Company and do
not use or hold and are deemed not to use or hold their Common Shares in the
course of carrying on a business in Canada and do not carry on insurance
business in Canada. This summary has been prepared by reference to the existing
provisions of the Income Tax Act (Canada) (the "Act"), the Income Tax
Regulations (the "Regulations"), all published proposals for the amendment of
the Act and the Regulations to the date hereof and the published administrative
practices of Revenue Canada, the agency that administers the Act. Although this
summary does not specifically address the provincial income tax consequences of
an investment in Common Shares, generally speaking, provincial taxation does not
apply to persons who are not resident in Canada and who do not own or hold
property in the course of carrying on a business in Canada. Apart from changes
to the Act and the Regulations which have been publicly announced to the date
hereof, this summary does not consider the potential for any future alterations
to Canadian income tax legislation.

    DISPOSITIONS OF COMMON SHARES A nonresident of Canada will only be subject
to taxation in Canada under the Act in respect of a disposition of Common Shares
if such shares constitute "taxable Canadian property" to such nonresident.
Provided that the Common Shares are listed on a recognized stock exchange in
Canada at the time of a disposition, they will only constitute "taxable Canadian
property" to a holder if the holder, either alone or together with persons with
whom the holder does not deal at arm's length, owns or at any time in the five
years prior to the date of 

                                     - 38 -
<PAGE>
dispositions, has owned in excess of 25% of the issued and outstanding shares of
a class or series of the capital of the Company. Persons who are related by
blood or marriage, or are subject to common control are deemed to deal otherwise
than at arm's length; other persons may also be considered to be dealing
otherwise than at arm's length in certain circumstances. For the purposes of
determining the 25% threshold, rights or options to acquire Common Shares will
be treated as ownership thereof. Subject to the comments set out below in
respect of the application of the U.S. -- Canada Income Tax Convention to U.S.
resident holders, nonresidents whose shares constitute "taxable Canadian
property" will be subject to taxation thereon on the same basis as Canadian
residents. Generally speaking, three-quarters of the excess of the holder's
proceeds of disposition, over the adjusted cost base of the Common Shares, must
be included in income as a taxable capital gain, to be taxed at prevailing
federal Canadian rates, which range from approximately 26% to 39%.

    Nonresidents whose shares are repurchased by the Company, except in respect
of certain purchases made by the Company in the open market, will give rise to
the deemed payment of a dividend by the Company to the former holder of Common
Shares in an amount equal to the excess paid over the paid-up capital of the
Common Shares so repurchased. Such deemed dividend will be excluded from the
former holders' proceeds of disposition of his Common Shares for the purposes of
computing any capital gain but will be subject to Canadian nonresident
withholding tax in the manner described below under "Dividends." In certain
limited circumstances, a sale by a holder of the Common Shares to a corporation
resident in Canada with which the holder does not deal at arm's length may give
rise to the deemed payment of a dividend, to the extent the amount received in
consideration therefor exceeds the paid-up capital of the Common Shares disposed
of.

    Pursuant to the U.S. -- Canada Income Tax Convention (the "Convention"),
shareholders of the Company who are resident in the U.S. for the purposes of the
Convention and whose shares might otherwise be "taxable Canadian property" may
be exempt from Canadian taxation in respect of any gains on the Common Shares
provided the principal value of the Company is not derived from real property
located in Canada at the time of the disposition.

    The Company owns no Canadian real property and the Company has no present
intention to acquire Canadian real property.

    DIVIDENDS Under the Act, withholding tax is imposed at the rate of 25% on
the amount of any dividends paid or credited on the Common Shares to a person
not resident in Canada. Pursuant to the Canada U.S. -- Canada Income Tax
Convention, the rate of tax on such dividends is reduced to 6% for dividends
received in 1996 and 5% thereafter by any U.S. resident corporation who owns in
excess of 10% of the voting shares of the corporation, and to 15% in all other
instances.

INVESTMENT CANADA ACT

    The Investment Canada Act (the "ICA") prohibits the acquisition of control
of a Canadian business by non-Canadians without review and approval of the
Investment Review Division of Industry Canada, the agency that administers the
ICA, unless such acquisition is exempt from review under the provisions of the
ICA. Investment Review Division of Industry Canada must be notified of such
exempt acquisitions. The ICA covers acquisitions of control of corporate
enterprises, whether by purchase of assets, shares of "voting interests" of an
entity that controls, directly or indirectly, another entity carrying on a
Canadian business. The ICA will have no effect on the acquisition of shares
covered by this Prospectus.

                                     - 39 -
<PAGE>
    Apart from the ICA, there are no other limitations on the right of
nonresident or foreign owners to hold or vote securities imposed by Canadian law
or the Certificate of Continuance of the Company. There are no other decrees or
regulations in Canada which restrict the export or import of capital, including
foreign exchange controls, or that affect the remittance of dividends, interest
or other payments to nonresident holders of the Company's Common Shares except
as discussed above.


ITEM 12.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    The Yukon BUSINESS CORPORATIONS ACT and the Company's Bylaws provide the
following authority to indemnify directors or officers or former directors or
officers of the Company or of a company of which the Company is or was a
shareholder:

(1) Except in respect of an action by or on behalf of the corporation or a body
    corporate to procure a judgment in its favor, a corporation may indemnify a
    director or officer of the corporation, a former director or officer of the
    corporation or a person who acts or acted at the corporation's request as a
    director or officer of a body corporate of which the corporation is or was a
    shareholder or creditor, and his heirs and legal representatives, against
    all costs, charges and expenses, including an amount paid to settle an
    action or satisfy a judgment, reasonably incurred by him in respect of any
    civil, criminal or administrative action or proceeding to which he is made a
    party by reason of being or having been a director or officer of that
    corporation or body corporate, if (a) he acted honestly and in good faith
    with a view to the best interests of the corporation, and (b) in the case of
    a criminal or administrative action or proceeding that is enforced by a
    monetary penalty, he had reasonable grounds for believing that his conduct
    was lawful.

(2) A corporation may, with the approval of the Supreme Court, indemnify a
    person referred to in subsection (1) in respect of an action by or on behalf
    of the corporation or body corporate to procure a judgment in its favor, to
    which he is made a party by reason by being or having been a director or an
    officer of the corporation or body corporate, against all costs, charges and
    expenses reasonably incurred by him in connection with the action if he
    fulfills the conditions set out in paragraphs (1)(a) and (b).

    The Yukon BUSINESS CORPORATIONS ACT also provides that:

(3) Notwithstanding anything in subsections (1) through (6), a person referred
    to in subsection (1) is entitled to indemnity from the corporation in
    respect of all costs, charges and expenses reasonably incurred by him in
    connection with the defense of any civil, criminal or administrative action
    or proceeding to which he is made a party by reason of being or having been
    a director or officer of the corporation or body corporate, if the person
    seeking indemnity (A) was substantially successful on the merits of his
    defense of the action or proceeding, (B) fulfills the conditions set out in
    paragraphs (1)(a) and (b), and (C) is fairly and reasonably entitled to
    indemnity.

(4) A corporation may purchase and maintain insurance for the benefit of any
    person referred to in subsection (1) against any liability incurred by him
    (a) in his capacity as a director or officer of the corporation, except when
    the liability relates to his failure to act honestly and in good faith with
    a view to the best interests of the corporation, or (b) in his capacity as a
    director or officer of another body corporate if he acts or acted in that
    capacity at the corporation's 

                                     - 40 -
<PAGE>
    request, except when the liability relates to his failure to act honestly
    and in good faith with a view to the best interests of the body corporate.

(5) A corporation or a person referred to in subsection (1) may apply to the
    Supreme Court for an order approving an indemnity under this section and the
    Supreme Court may so order and make any further order it thinks fit.

(6) On an application under subsection (5), the Supreme Court may order notice
    to be given to any interested person and that person is entitled to appear
    and be heard in person or by counsel.

    The Bylaws of the Company also provide that the provisions for
indemnification contained in the Bylaws (outlined in subsections (1) and (2)
above) shall not be deemed exclusive of any other rights to which a person
seeking indemnification may be entitled under any Bylaws, agreement, vote of
shareholders or disinterested directors or otherwise both as to an action in his
official capacity and as to an action in any other capacity while holding such
office and shall continue as to a person who has ceased to be a director of
officer and shall enure to the benefit of the heirs and legal representatives of
such person. The Company maintains director's and officer's insurance.

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers, or persons controlling the
Company pursuant to the foregoing provisions, the Company has been informed that
in the opinion of the Securities and Exchange Commission, such indemnification
is against public policy as expressed in the Act and is therefore unenforceable.

                          GLOSSARY OF TECHNICAL TERMS

ANTICLINAL TRAP means a subsurface, geological structure in the form of a sine
curve (i.e., the information rises to a rounded peak) as a result of which any
oil in the deposit will normally rise to the highest point in the structure.

APPRAISAL WELL means a well drilled subsequent to a discovery well in order to
confirm potential recoverable reserve quantities prior to development drilling
of the field.

AQUIFER means water bearing rock structure.

BOPD means barrels of oil per day.

COMMISSION means the U.S. Securities and Exchange Commission.

COMPLETION means the installation of permanent equipment for the production of
crude oil or gas, or in the case of a dry hole, the reporting of abandonment to
the appropriate agency.

DEVELOPMENT WELL means a well drilled within the proved area of a oil or gas
reservoir to the depth of a strategraphic horizon known to be productive.

DRILL STEM TEST means a method of determining the presence of oil and gas in a
formation. When the depth to be tested has been reached in a well being drilled,
a special tool is lowered into the hole. The drilling mud is removed and the
contents of the formation allowed to flow into the tool while an instrument
measures the pressure.

ECOPETROL means Empresa Colombiana de Petroleos, the Colombian national oil
company.

EXPLORATORY WELL means a well drilled to find and purchase oil and gas reserves
not classified as proved, to find a new reservoir in a field previously found to
be productive of oil and gas in another reservoir or to extend a known
reservoir.

FARMOUT means an agreement whereby the owner of a lease agrees to assign or
transfer the lease (or some portion of it), retaining some interest (such as an
overriding royalty or right to share in production), subject to the drilling of
one or more wells as a prerequisite to completion of the transfer by him.

MMBO means one million barrels of crude oil.

OPERATOR means any person, partnership, corporation or other entity engaged in
the business of exercising direct supervision over the drilling or completion of

production exceed production expenses and taxes.

PROVEN DEVELOPED PRODUCING RESERVES means those proved reserves that are
actually on production or, if not producing, that could be recovered from
existing wells or facilities and where the reasons for the current non-producing
status is the choice of the owner rather than the lack of markets or some other
reasons. An illustration of such a situation is where a well or zone is capable
but is shut-in because its deliverability is not required to meet contract
commitments.
<PAGE>
PROVEN RESERVES means those reserves estimated as recoverable under current
technology and existing economic conditions, from that portion of a reservoir
which can be reasonably evaluated as economically productive on the basis of
analysis of drilling, geological, geophysical and engineering data, including
the reserves to be obtained by enhanced recovery processes demonstrated to be
economic and technically successful in the subject reservoir.

PROVEN UNDEVELOPED RESERVES means those proved reserves that are not currently
producing either due to lack of facilities and/or markets.

RESERVOIR means a porous permeable sedimentary rock containing commercial
quantities of oil or gas.

<PAGE>
                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Stockholders of Seven Seas Petroleum Inc.:

We have audited the accompanying consolidated balance sheets of Seven Seas
Petroleum Inc. (a Yukon Territory, Canada, corporation) and subsidiaries as of
December 31, 1996 and 1995, and the related consolidated statements of
operations and accumulated deficit, stockholders' equity and cash flows for the
year ended December 31, 1996, and for the period from inception (February 3,
1995) through December 31, 1995. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Seven Seas Petroleum
Inc. and subsidiaries as of December 31, 1996 and 1995, and the results of their
operations and their cash flows for the year ended December 31, 1996, and for
the period from inception (February 3, 1995) through December 31, 1995, in
conformity with generally accepted accounting principles (Note 3).

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                (In U.S. Dollars)

1.       NATURE OF OPERATIONS:

Seven Seas Petroleum Inc. (a Yukon Territory, Canada, corporation) was formed on
February 3, 1995. Seven Seas Petroleum Inc. and its subsidiaries, Seven Seas
Petroleum Holdings Inc., Seven Seas Petroleum Argentina Inc., Seven Seas
Petroleum Australia Inc., Seven Seas Petroleum Colombia Inc., Seven Seas
Petroleum Mediterranean Inc., Seven Seas Petroleum Turkey Inc., Seven Seas
Petroleum PNG Inc., Seven Seas Petroleum U.S.A. Inc., GHK Company Colombia,
Esmeralda LLC and Cimarrona LLC, are collectively referred to herein as "Seven
Seas" or "the Company." The Company's business is to acquire, explore and
develop interests in oil and gas projects worldwide.

At December 31, 1996, the Company's unevaluated oil and gas interests were
recently acquired and are in the initial stages of evaluation and development.
Accordingly, the recoverability of such amounts is dependent upon the completion
of exploration work, the discovery of oil and gas reserves in commercial
quantities and the subsequent development, production and sales of these
reserves. Recoverability is also dependent on the Company's ability to finance
the exploration and development activities through operations or outside
financing.

2.       BUSINESS COMBINATION:

On June 29, 1995, the Supreme Court of British Columbia approved an amalgamation
of Seven Seas and Rusty Lake Resources Ltd. Stockholders of Rusty Lake Resources
Ltd. were issued one common share in Seven Seas, the new company after the
amalgamation, for each 35 common shares held in Rusty Lake Resources Ltd.
Additional shares of Seven Seas were issued in settlement of certain
indebtedness of Rusty Lake Resources Ltd. This transaction has been reflected as
an acquisition by Seven Seas using the purchase method of accounting. The net
assets of Rusty Lake Resources Ltd. were recorded on the books of Seven Seas as
follows:

             Marketable securities                      $   3,370
             Goods and services tax receivable              3,099
             Resource properties                          115,693
             Other assets (organization costs)             87,481
             Accounts payable                             (39,527)
             Share capital (680,464 shares)              (170,116)

On July 26, 1996, the Company acquired 100 percent of the outstanding stock
which represented 100 percent of the voting shares held in GHK Company Colombia
and Esmeralda LLC. Additionally, on the same date, the Company acquired 62.963
percent of the outstanding shares and voting stock in Cimarrona LLC. This
transaction has been reflected as an acquisition by Seven Seas using the
purchase method of accounting. Seven Seas issued to the stockholders in GHK
Company Colombia, Esmeralda LLC and Cimarrona LLC a combination of preferred
shares and special warrants which are exchangeable into a total of 16,777,143
common shares upon the earlier of the receipting of a prospectus qualifying the
exchange, or one year from the closing of the transaction. Of the 16,777,143
preferred shares and special warrants, 5,002,972 preferred shares were issued
for all of the common shares in GHK Company Colombia, 4,469,028 special warrants
were issued for all of the common shares in Esmeralda LLC and 7,305,143 special
warrants were issued for 62.963 percent of the common shares in Cimarrona LLC.
The remaining 37.037 percent interest in Cimarrona represents a minority
interest which is reflected as such on the balance sheet. The 16,777,143
preferred shares and special warrants were recorded based on the closing stock
price of Seven Seas on July 26, 1996, at $9.125, totaling $153,091,430. Net
assets acquired include $153,122,523 assigned to oil and

                                      F-6

gas properties (which are subject to future evaluation based on further
appraisal drilling) and other nominal net working capital, less amounts
attributable to the minority interest in Cimarrona LLC. Any income and
expenditures incurred by these three entities after July 26, 1996, are included
in the current year's statement of operations and accumulated deficit.

Of the 16,777,143 preferred shares and special warrants issued, 11,744,000 are
held subject to an escrow agreement, whereby one-third of the Securities are
released each year for three years. The Securities may be released earlier based
upon a valuation of the Seven Seas interests in the contract areas.
Collectively, the acquisition of these three companies resulted in the purchase
of an additional 36.7 percent participating interest in the Dindal and Rio Seco
Blocks in Colombia in which the Company previously held a 15 percent
participating interest. All three entities were oil and gas exploration
companies whose only material asset was the participating interest they held in
the Dindal and Rio Seco Association contracts in Colombia.

3.       SUMMARY OF SIGNIFICANT

    ACCOUNTING POLICIES:

The Company follows accounting principles generally accepted in Canada. A
summary of the Company's significant policies is set out below.

CONSOLIDATION

These consolidated financial statements include the accounts of Seven Seas
Petroleum Inc. and its wholly owned subsidiaries named in Note 1.

CASH AND CASH EQUIVALENTS

Cash and cash equivalents include bank deposits and short-term investments
which, upon acquisition, have a maturity of three months or less.

MARKETABLE SECURITIES

Marketable securities are recorded at the lower of cost or market value.
Declines in market value below carrying value are written down through earnings.
Marketable securities include $14,700 which is restricted until June 4, 1997.

OIL AND GAS INTERESTS

The Company follows the full-cost method of accounting for oil and natural gas
operations, whereby all costs incurred for exploration and development of oil
and natural gas properties are capitalized in country-by-country cost centers.
Such costs include land acquisition costs, geological and geophysical costs,
costs of drilling both productive and nonproductive wells, related plant and
production equipment costs, carrying costs of nonproductive properties and that
portion of administration costs applicable to exploration and development
activities. Proceeds received from the disposal of properties are normally
credited against accumulated costs. No gains or losses are recognized upon the
disposition of oil and natural gas properties except under circumstances which
result in a major disposal of reserves.

The costs of acquiring and evaluating properties are initially excluded from
depletion calculations. These properties are assessed periodically to ascertain
whether impairment has occurred. When evaluated reserves are assigned or when
the property is considered impaired, the cost of the property is added to the
costs subject to depletion. Depletion is recorded on the unit-of-production
basis. If the net capitalized costs of oil and gas properties (net of recorded
deferred taxes and accumulated provision for site restoration and abandonment
costs) in a cost center exceed an amount equal to the sum of the undiscounted
estimated future
<PAGE>
                                       -3-

net revenues from evaluated oil and gas reserves in the cost center (net of site
restoration and abandonment costs, interest, production-related general and
administrative costs) and the costs of properties not being amortized, both
adjusted for income tax effects, such excess is charged to expense.

Substantially all the Company's exploration and production activities are
conducted jointly with others, and the accounts reflect only the Company's
proportionate interest in such activities.

FOREIGN CURRENCY TRANSLATION

The Company's reporting and functional currency is U.S. dollars. Foreign
operations which generally are financially and operationally interdependent with
the parent company are accounted for using the temporal method. Monetary items
are translated using the exchange rate in effect at the balance sheet date;
nonmonetary items are translated at historical exchange rates. Revenues and
expenses are translated at the average rates in effect on the dates they occur.
No material translation gains or losses were recorded during the period.

INCOME TAXES

The deferral method of tax allocation is followed under which the income tax
provision is based on the results of operations reported in the accounts. The
difference between the income tax provision and taxes currently payable would be
reflected as deferred income taxes. For the year ended December 31, 1996, the
Company has recorded tax expense of $2,338. No deferred tax benefits have been
recognized for 1996 or 1995 because the realization of these tax benefits cannot
be reasonably assured.

FIXED ASSETS

Fixed assets are recorded at cost. Depreciation is provided on a straight-line
basis over three to five years.

ORGANIZATION COSTS

Organization costs represent the normal cost of incorporating the Company. In
association with the amalgamation agreement with Rusty Lake Resources Ltd.,
organization costs of $87,481 were recorded to reflect the excess purchase price
of Seven Seas common shares provided to Rusty Lake Resources Ltd. stockholders
over and above the net asset value of Rusty Lake Resources Ltd. as of June 29,
1995. Organization costs are being amortized on a straight-line basis over two
years.

EARNINGS PER SHARE

Basic earnings (loss) per common share are calculated using the weighted average
number of shares outstanding during the period. Fully diluted loss per share has
not been presented as it is antidilutive.

EXPLORATION COSTS

The Company has been involved in exploration activities in Colombia, Australia,
Argentina, Turkey and Papua New Guinea and, also, the Company purchased an
option for the right to participate in future exploration activities in North
Africa, but the option was never exercised. Additionally, the Company acquired
oil and gas properties in Columbia during 1996 totaling $153,122,523 and $57,624
of exploration costs were incurred also in 1996 which were reclassified as
evaluated oil and gas interests. In the third and fourth quarters of 1996, the
Company had oil and gas sales of $233,682 which pertained solely to production
testing of two wells located in Colombia. During the period ending December 31,
1995, exploration costs incurred of $622,006 in Argentina and $500,800 for the
option in North Africa were expensed.

On May 16, 1995, the Company entered into an agreement whereby Seven Seas
purchased an option for $500,000 to acquire a 5 percent participating interest
in three exploration blocks in North Africa upon completion of the first
exploration well drilled. The first exploration well was completed as a dry hole
in July of 1995. After careful review, Seven Seas decided not to exercise its
option. The cost of the well and the option, $500,000, plus additional costs of
$800 incurred toward purchasing this option, were originally recorded as
unevaluated oil and gas interests and were subsequently expensed.

The El Catamarqueno X-1 test well on the Sur Rio Deseado Block in the San Jorge
Basin, Argentina, was determined to be unsuccessful during January of 1996. The
Company determined that further drilling on the block was not justified and,
therefore, expensed exploration interests in Argentina of $622,006.

Empresa Colombiana de Petroleos, the Colombian national oil company (Ecopetrol),
has the right to back into Seven Seas Dindal and Rio Seco Association contracts
in Colombia upon declaration of commerciality at an initial 50 percent
participating interest. Ecopetrol's interest can increase based upon accumulated
production levels. Ecopetrol will at the time of commerciality bear 50 percent
of the future costs in the field and reimburse the other parties in these two
blocks for 50 percent of previously incurred costs associated with successful
exploratory and appraisal wells.

A brokered private placement involving the issuance of 2,000,000 special
warrants at $2.75 per warrant for a net offering after commissions and expenses
of $5,095,548 was completed in Canada on March 15, 1996. Each special warrant is
convertible into one unit. Each unit consists of one share of common stock and a
one-half common share purchase warrant at $3.50 per full share. The warrants are
convertible at the earlier of (a) one year from date of issuance or (b) the date
a receipt is issued for a prospectus qualifying the conversion in the
appropriate jurisdictions (see Subsequent Events).

A brokered private placement involving the issuance of 500,000 special warrants
at $15.00 per warrant for a net offering after commissions and expenses of
$7,013,370 was completed in Canada on October 16, 1996. Each special warrant is

The proceeds of the March 15 and October 16, 1996, private placements will be
used for additional drilling, seismic and production facilities on the Company's
51.7 percent participating interest in the Emerald Mountain, Colombia, oil
discovery and for further exploration activities.

See Note 2 for discussion of other securities issued.

8.       COMMITMENTS AND CONTINGENCIES:

The Company is committed to make minimum payments under contracts for certain
office facilities and equipment. Amounts due under these contracts as of
December 31, 1996, are as follows: $63,799 for 1997, $54,902 for 1998, $25,138
for 1999 and none thereafter.

Two wells estimated at a total cost of $7,600,000 are required to be drilled on
the Company's Rio Seco and Dindal Blocks in Colombia by August and September
1997, respectively, to fulfill the Company's 1997 work commitment on these two
blocks. The Company will be required to pay its proportionate share of the total
cost of these two wells.

9.       SUBSEQUENT EVENTS:

On March 5, 1997, the Company acquired 100 percent of the outstanding stock
which represented 100 percent of the voting shares held in Petrolinson, S.A. The
terms of the transaction were agreed to in a letter of intent dated November 22,
1996. The principal asset owned by Petrolinson, S.A., is a 6 percent
participating interest in the Dindal and Rio Seco Association contracts. As
consideration for the 6 percent interest in the Dindal and Rio Seco Association
contracts, Seven Seas issued to the sole stockholder in Petrolinson, S.A.,
1,000,000 common shares of Seven Seas Petroleum Inc. common stock. The common
shares issued to Petrolinson, S.A., will be subject to an escrow agreement, the
terms of which provide for a 120-day escrow of shares commencing from March 5,
1997. This 6 percent interest will be carried through exploration by the other
94 percent participating interest parties. This transaction will be reflected in
1997 as an acquisition by Seven Seas using the purchase method of accounting.
The 1,000,000 shares will be recorded based on the average
<PAGE>
                                       -7-

closing stock price of Seven Seas for the period beginning 30 days prior to and
30 days subsequent to November 22, 1996, or $18.55. This represents a
transaction cost of $18,550,000. Net assets acquired include $18,537,321
assigned to oil and gas properties (which are subject to future evaluation based
on further appraisal drilling) and other nominal net working capital.

On February 6, 1997, approvals were granted by the Ontario Securities
Commission, British Columbia Securities Commission and the Alberta Securities
Commission receipting a prospectus filed to qualify 2,500,000 special warrants
as common stock pertaining to the March and October 1996 financings.
Additionally, the prospectus qualified 11,774,171 special warrants and 5,002,972
preferred shares as common stock which was issued in connection with the
acquisition of a 36.7 percent participating interest in the Dindal and Rio Seco
Association contracts in Colombia by the Company on July 26, 1996.

10.      DIFFERENCES IN GENERALLY ACCEPTED
         ACCOUNTING PRINCIPLES BETWEEN
         CANADA AND THE UNITED STATES:

The consolidated financial statements have been prepared in accordance with
generally accepted accounting principles (GAAP) in Canada. No material
modifications would be necessary to the financial statements to comply with
generally accepted accounting principles in the United States.

11.      SUPPLEMENTAL OIL AND GAS

     INFORMATION (UNAUDITED):

PRODUCING PROPERTIES

Proved reserves represent estimated quantities of crude oil which geological and
engineering data demonstrate to be reasonably recoverable in the future from
known reservoirs under existing economic and operating conditions. Estimates of
proved developed oil reserves are subject to numerous uncertainties inherent in
the process of developing the estimates including the estimation of the reserve
quantities and estimated future rates of production and timing of development
expenditures. The accuracy of any reserve estimate is a function of the quantity
and quality of available data and of engineering and geological interpretation
and judgment. Results of drilling, testing and production subsequent to the date
of the estimate may justify revision of such estimate. Additionally, the
estimated volumes to be commercially recoverable may fluctuate with changes in
prices of oil. The proved reserves at December 31, 1996, are based only upon the
results of the drilling of the El Segundo No. 1 well on the Dindal Block in
Colombia.

Estimates of future recoverable oil reserves and projected future net revenues
were provided by Sproule International Limited. The Company's proved reserves
were comprised entirely of crude oil in Colombia and are stated in barrels.

Proved developed and undeveloped reserves (number of barrels at December 31,
1996):

The following table presents the standardized measure of discounted future net
cash flows relating to proved oil reserves. Future cash inflows and costs were
computed using prices and costs in effect at the end of the applicable year
without escalation. Crude oil prices at December 31, 1996, were $25.93 per
barrel for West Texas Intermediate as compared to the average for the year of
$22.13. Therefore, a crude price of $22.13
<PAGE>
                                       -8-

unescalated, less a $3.00 gravity adjustment, was used in calculating the
standardized measure of discounted future net cash flows, as the December 1996
year-end price of $25.93 was not representative of current or future pricing.
Future income taxes were computed by applying the appropriate statutory income
tax rate to the pretax future net cash flows reduced by future tax deductions
and net operating loss carryforwards.

The standardized measure of discounted future net cash flows does not purport to
present the fair market value of the Company's proved reserves. An estimate of
fair value would also take into account, among other things, the recovery of
reserves in excess of evaluated reserves, anticipated future changes in prices
and costs and a discount factor more representative of the time value of money
and the risks inherent in reserve estimates.

CLASS A PREFERRED SHARES - SERIES 1

    The first series of Class A Preferred shares of the Corporation shall
consist of an unlimited number of shares and shall be designated as the Class A
Preferred Shares - Series 1
<PAGE>
(the "Class A Preferred Shares - Series 1"). The rights, privileges,
restrictions and conditions attaching to the Class A Preferred Shares - Series 1
are as follows:

    (a) each Class A Preferred Share Series 1 shall entitled the holder thereof
        to receive notice of, to attend and to vote at general meetings of the
        members of the Company on the basis of one vote per share held;

    (b) subject to Article 23.2(e) below, each Class A Preferred Share Series 1
        shall be convertible, at the option of the holder thereof, into common
        shares of the Company (the "Common Shares") on the basis of one Common
        Share for each Class A Preferred Share Series 1 held at any time and
        from time to time after the date of issuance of such share and up to
        5:00 o'clock in the afternoon, Vancouver time, on the earlier of:

        (i) the fifth business day after the day on which a receipt is issued
            for a final prospectus qualifying the conversion of Class A
            Preferred Shares Series 1 into Common Shares by the last of the
            securities commissions of British Colombia, Ontario and Alberta to
            issue such a receipt; or

        (ii) one year from the date of issuance of such Class A Preferred Shares
            Series 1;

        (the "Deemed Conversion Date");

        (c) subject to Article 23.2(e) below, each outstanding Class A Preferred
            Share Series 1 shall be automatically converted into one Common
            Share immediately prior to 5:00 o'clock in the afternoon, Vancouver
            time, on the Deemed Conversation Date;

        (d) Before any holder of Class "A" Preferred Shares Series 1 shall be
            entitled to convert the same into Common Shares, such holder shall
            surrender the certificate or certificates therefor, duly endorsed,
            at the Registered Office of the Company and shall give written
            notice to the Company at its Registered Office of the election to
            convert the same and shall state therein the name or names in which
            the certificate or certificates for Common Shares are to be issued.
            The Company shall, as soon as practicable thereafter, issue and
            deliver to such holder of Class A Preferred Shares Series 1, or to
            the nominee or nominees or such holder, a certificate or
            certificates for the number of Common Shares to which such holder
            shall be entitled as aforesaid. Such conversion shall be deemed to
            have been made immediately prior to 5:00 o'clock in the afternoon,
            Vancouver time, on the date of such surrender of Class A Preferred
            Shares Series 1 to be converted, and the person or persons entitled
            to receive Common Shares issuable upon such conversion shall be
            treated for all purposes as the record holder or holders of such
            Common Shares as of such date;

                                       -2-
<PAGE>
        (e) The number of Common Shares into which the Class A Preferred Shares
            Series 1 shall convert shall be subject to adjustment from time to
            time as follows:

            (i) if and whenever at any time from the date hereof and prior to
                5:00 o'clock in the afternoon, Vancouver time, on the Deemed
                Conversion Date, the Company shall:

                A.  subdivide, redivide or change its outstanding Common Shares
                    into a greater number of shares;

                B.  reduce, combine or consolidate its outstanding Common Shares
                    into a smaller number of shares, or

                C.  issue Common Shares or securities exchangeable or
                    convertible to Common Shares ("Convertible Securities") to
                    the holders of all or substantially all of the outstanding
                    Common Shares by way of a stock dividend or other
                    distribution;

                the number of Common Shares into which a Class A Preferred Share
                Series 1 shall convert shall each be adjusted immediately after
                the effective date of the events referred to in A. and B. above
                or the record date for the issue of the Common Shares or the
                Convertible Securities referred to in C. above by multiplying
                the number of Common Shares theretofore obtainable on the
                conversion of the Class A Preferred Shares Series 1 by a
                fraction of which the numerator shall be the total number of
                Common Shares outstanding immediately after such date or, in the
                case of the issue of convertible securities the total number of
                Common Shares outstanding immediately after such date plus the
                total number of Common Shares issuable upon conversion or
                exchange of such convertible securities and the denominator
                shall be the total number of Common Shares outstanding
                immediately prior to such date. Such adjustment shall be made
                successively whenever any event referred to in this subsection
                shall occur and any issue of Common Shares or convertible
                securities by way of a stock dividend is deemed to have occurred
                on the record date for such dividend for the purpose of
                calculating the number of outstanding Common Shares under this
                subsection;

           (ii) if and whenever at any time from the date hereof and prior to
                5:00 o'clock in the afternoon, Vancouver time, on the Deemed
                Conversion Date, there is a reclassification or redesignation of
                the Common Shares or a capital reorganization of the Company
                other than as described in Article 23.2(e)(i) or a
                consolidation, arrangement, amalgamation or merger of the
                Company with or into any other body corporate, trust,
                partnership or other entity, or a sale or conveyance of the

                                       -3-
<PAGE>
                property and assets of the Company as an entirety or
                substantially as an entirety to any other body corporate, trust,
                partnership or other entity, any holder of Class A Preferred
                Shares Series 1 who has not exercised his right of conversion
                prior to the effective date of such reclassification,
                redesignation, capital reorganization, consolidation,
                arrangement, amalgamation, merger, sale or conveyance, upon the
                exercise of such right thereafter, shall be entitled to receive
                and shall accept, in lieu of the number of Common Shares then
                sought to be acquired by him, the number of shares or other
                securities or property of the Company or of the body corporate,
                trust, partnership or other entity resulting from such merger,
                amalgamation, arrangement, or consolidation, or to which such
                sale or conveyance may be made, as the case may be, that such
                shareholder would have been entitled to receive on such
                reclassification, redesignation, capital reorganization,
                consolidation, arrangement, amalgamation, merger, sale or
                conveyance, if, on the record date or the effective date
                thereof, as the case may be, such holder of the Class A
                Preferred Shares Series 1 had been the registered holder of the
                number of Common Shares receivable upon the conversion of Class
                A Preferred Shares Series 1 then held. If determined appropriate
                by the Company to give effect to or to evidence the provisions
                of this subsection, the Company, its successor, or such
                purchasing body corporate, partnership, trust or other entity,
                as the case may be, shall, prior to or contemporaneously with
                any such reclassification, redesignation, capital
                reorganization, consolidation, amalgamation, arrangement,
                merger, sale or conveyance, enter into an agreement which shall
                provide, to the extent possible, for the application of the
                provisions set forth in these Articles with respect to the
                rights and interests thereafter of the holders of the Class A
                Preferred Shares Series 1 to the end that the provisions set
                forth in these Articles shall thereafter correspondingly be made
                applicable, as nearly as may reasonably be, with respect to any
                shares, other securities or property to which a holder of the
                Class A Preferred Series 1 is entitled on the exercise of his
                conversion rights thereafter. Any agreement entered into between
                the Company, any successor to the Company or such purchasing
                body corporate, partnership, trust or other entity and the
                holders of the Class A Preferred Shares Series 1 shall provide
                for adjustments which shall be as nearly equivalent as may be
                practicable to the adjustments provided in this Article 23.2 and
                which shall apply to successive reclassifications,
                redesignations, capital reorganizations, consolidations,
                arrangements, amalgamations, mergers, sales or conveyances;

          (iii) in any case in which this Article 23.2 shall require that an
                adjustment shall become effective immediately after a record
                date for an event referred to herein, the Company may defer,
                until the occurrence of such 

                                       -4-
<PAGE>
                event, issuing to the holder of any Class A Preferred Share
                Series 1 converted after such record date and before the
                occurrence of such event the additional Common Shares issuable
                upon such conversion by reason of the adjustment required by
                such event before giving effect to such adjustment; provided,
                however, that the Company shall deliver to such shareholder an
                appropriate instrument evidencing such shareholder's right to
                receive such additional Common Shares upon the occurrence of the
                event requiring such adjustment and the right to receive any
                distributions made on such additional Common Shares which may be
                acquired upon the conversion of Class A Preferred Shares Series
                1 declared in favor of holders of record of Common Shares on and
                after the date of conversion or such later date as such
                shareholder would, but for the provisions of this subsection
                (iii), have become the holder of record of such additional
                Common Shares pursuant to this Article 23.2;

           (iv) the adjustments provided for in this Article 23.2(e) in the
                number of Common Shares and classes of securities which are to
                be received on the conversion of Class A Preferred Shares Series
                1, are cumulative. After any adjustment pursuant to this Article
                23.2(e), the term "Common Shares" where used in this Article
                23.2 shall be interpreted to mean securities of any class or
                classes which, as a result of such adjustment and all prior
                adjustments pursuant to this Article 23.2(e), a holder of Class
                A Preferred Shares Series 1 is entitled to receive upon the
                exercise of his Class A Preferred Shares Series 1, and the
                number of Common Shares indicated by any conversion made
                pursuant to a Class A Preferred Share Series 1 shall be
                interpreted to mean the number of Common Shares or other
                property or securities a holder of Class A Preferred Shares
                Series 1 is entitled to receive, as a result of such adjustment
                and all prior adjustments pursuant to this Article 23.2(e), upon
                the full exercise of a Class A Preferred Share Series 1;

            (v) in the event of any question arising with respect to the
                adjustments provided for in this Article 23.2(e) such question
                shall be conclusively determined by the Company's auditors who
                shall have access to all necessary records of the Company, and
                such determination shall be binding upon the Company, all
                holders of Class A Preferred Shares Series 1 and all other
                persons interested therein;

           (vi) as a condition precedent to the taking of any action which
                would require an adjustment in the conversion right attaching to
                the Class A Preferred Shares Series 1, the Company shall take
                any corporate action which may, in the opinion of counsel, be
                necessary in order that the Company has unissued and reserved in
                its authorized capital and may validly and legally issue as
                fully paid and non-assessable all the shares which the holders
                of 

                                       -5-
<PAGE>
                such Class A Preferred Shares Series 1 are entitled to receive
                on the full conversion thereof in accordance with the provisions
                hereof;

          (vii) if and whenever at anytime prior to 5:00 o'clock in the
                afternoon, Vancouver time, on the Demand Conversion Date, the
                Company shall take any action affecting or relating to the
                Common Shares, other than any action described in this Article,
                which in the opinion of the directors would prejudicially affect
                the rights of any holders of Class A Preferred Shares Series 1,
                the conversion rights in effect on any date attaching to the
                Class A Preferred Shares Series 1 will be adjusted by the
                directors in such manner, if any, and at such time, as the
                directors may, in their sole discretion, determine to be
                equitable in the circumstances to such holders of Class A
                Preferred Shares Series 1;

         (viii) all shares of any class, other securities which a holder of
                Class A Preferred Shares Series 1 is at the time in question
                entitled to receive on the conversion of Class A Preferred
                Shares Series 1, whether or not as a result of adjustments made
                pursuant to this Article 23.2(e), shall for the interpretation
                of this Article 23.2, be deemed to be shares and other
                securities which such holder of Class A Preferred Shares Series
                1 is entitled to acquire pursuant to the Class A Preferred
                Shares Series 1;

           (ix) the Company shall from time to time immediately after the
                occurrence of an event which requires an adjustment or
                readjustment as provided in this Article 23.2(e) deliver a
                certificate of the Company to the holders of the Class A
                Preferred Shares Series 1 specifying the nature of the event
                requiring the same and the amount of the adjustment necessitated
                thereby and setting forth in reasonable detail the method of
                calculation and the facts upon which such calculation is based,
                which certificate and the amount of adjustment specified therein
                shall be verified by the holders of the Class A Preferred Shares
                Series 1;

        (f) no dividends shall be declared or payable on the Class A Preferred
            Shares Series 1;

        (g) the Class A Preferred Shares Series 1 shall not, in the event of
            liquidation, dissolution or winding up of the Company, whether
            voluntary or involuntary, entitle the holders thereof to participate
            in the distribution of the assets of the Company pursuant to the
            liquidation, dissolution or winding up; and

        (h) in the event that any Class A Preferred Shares Series 1 are
            converted pursuant to this Article 23.2, the shares so converted
            shall be cancelled and may not be reissued by the Company.

whose term of office has expired or then expires shall retire but, if qualified,
shall be eligible for re-election. A director not elected for an expressly

in office until their successors are elected. The number of directors to be
elected at any such meeting shall be the number of directors whose term of
office has expired or expires unless the directors or the shareholders otherwise

if a time is specified in such resignation, at the time so specified, whichever
is later.

4.07        VACANCIES

            Subject to the Act, a quorum of the board may fill a vacancy in the

if they fail to

                                      6

call such meeting or if they are no directors then in office, any shareholder

the corporation. A share certificate executed as aforesaid shall be valid
notwithstanding that one or both of the officers whose

                                      15
<PAGE>

substitution for a share certificate claimed to have been lost, destroyed or
wrongfully taken on payment of a reasonable fee, and on such terms as to

registered in the name of a shareholder or his legal representative for a debt
of that shareholder to the Corporation, such lien may be enforced, subject to
the Act and to any other provision of the articles by the sale of the shares

address, unless such holder otherwise directs. In the case of joint holders the
cheque shall, unless such joint holders otherwise direct, be made payable to the
order of all such joint holders and mailed to them at their recorded address.

            A meeting of shareholders may be held without notice at any time and
place permitted by the Act:

            (a)   if all shareholders entitled to vote thereat are present in
                  person or represented or if those not present or represented

            (b)   if the auditors and the directors are present or waive notice
                  of or otherwise consent to such meeting being held;

so long as such shareholders, auditors or directors present are not attending
for the express purpose of objecting to the transaction of any business on the
grounds that the meeting is not lawfully called. At such a meeting any business
may be transacted which the Corporation at a meeting of Shareholders may
transact. If the meeting is held at a place outside the Yukon Territory,
shareholders not present or represented by proxy, but who have waived notice of
or otherwise consented to such meeting, shall also be deemed to have consented
to the meeting being held at such place.

opening of any meeting of shareholders, the shareholders present or represented
may proceed with the business of the meeting notwithstanding that a quorum is

any meeting of shareholders, the shareholders present or represented may adjourn
the meeting to a fixed time and place but may not transact any other business

            Every person named in the list referred to in Clause 10.06 shall be

which such list relates, except to the extent that:

            (a)   where the Corporation has fixed a record date in respect of
                  such meeting, such person has transferred any of his shares
                  after such record date or, where the Corporation has not fixed
                  a record date in respect of such meeting, such person has
                  transferred any of his shares after the date on which such
                  list is prepared, and

            (b)   the transferee, having produced properly endorsed certificates
                  evidencing such shares or having otherwise established that he
                  owns such shares, has demanded not later than 10 days before
                  the meeting that his name be included in such list.

In any such excepted case the transferee shall be entitled to vote the
transferred shares at such meeting. If the Corporation is not required to
prepare a list under Clause 10.06, subject to the provisions of the Act and this
by-law as to proxies and representative, at any meeting of shareholders every
person shall be entitled to vote at the meeting who at the time is entered in
the securities register as the holder of one or more shares carrying the right
to vote at such meeting.

authorized and with the authority conferred by the proxy. A proxy shall be in
writing executed by the shareholder or his attorney and shall conform with the
requirements of the Act. Alternately, every such shareholder which is a body
corporate or association may

                                      21
<PAGE>
authorize by resolution of its directors or governing body an individual, who
need not be a shareholder, to represent it at a meeting of shareholders and such
individual may exercise on the shareholders behalf all the powers it could
exercise if it were an individual shareholder. The authority of such an
individual shall be established by depositing with the Corporation a certified
copy of such resolution, or in such other manner as may be satisfactory to the
secretary of the Corporation or the chairman of the meeting.

10.13       TIME FOR DEPOSIT OF PROXIES

            The board may specify in a notice calling a meeting of the
shareholders a time, preceding, the time of such meeting or an adjournment

proxies to be used at such meeting must be deposited. A proxy shall be acted
upon only if, prior to the time so specified, it shall have been deposited with
the Corporation or an agent thereof specified in such notice or, if no such time
is specified in such notice, it has been received by the secretary of the
Corporation or by the chairman of the meeting or any adjournment thereof prior
to the time of voting.

10.14       JOINT SHAREHOLDERS

            If two or more persons hold shares jointly, any one of them present

jointly held by them.

10.15       VOTES TO GOVERN

            At any meeting of shareholders every question shall, unless

who is present and entitled to vote shall have one vote. Whenever a vote by show
of hands shall have been taken upon a question, unless a ballot thereon is so
required or demanded, a declaration by the chairman of the meeting that the vote
upon the question has been carried or carried by a particular majority or not
carried and an entry

                                      22
<PAGE>
to that effect in the minutes of the meeting shall be prima faci evidence of the
fact without proof of the number or proportion of the votes recorded in favour
of or against any resolution or other proceeding in respect of the said
question, and the result of the vote so taken shall be the decision of the
shareholders upon the said question.

10.17       BALLOTS

            On any question proposed for consideration at a meeting of
shareholders, any shareholder or proxyholder entitled to vote at the meeting may
require or demand a ballot, either before or on the declaration of the result of
any vote by show of hands. A ballot so required or demanded shall be taken in
such manner as the chairman shall direct. A requirement or demand for a ballot
may be withdrawn at any time prior to the taking of the ballot. If a ballot is
taken each person present shall be entitled, in respect of the shares which he
is entitled to vote at a meeting upon the question, to that number of votes
provided by the Act or the articles, and the result of the ballot so taken shall
be the decision of the shareholders upon the said question.

10.18       ADMISSION OR REJECTION OF A VOTE

adjournments for an aggregate of 30 days or more, notice of the adjourned
meeting shall be given as for an original meeting.

10.20       RESOLUTION IN WRITING

            A resolution in writing signed by all the shareholders entitled to

the giving or in the time of such notice, as the case may be. Any such waiver or
abridgement shall be in writing except a waiver or notice of a meeting of
shareholders or of the board which may be given in any manner.

each class or series of securities:

            (a)   the names, alphabetically arranged, and the latest

            Subject to the provisions of the Act, no transfer of shares shall be
registered in a securities register except upon presentation of the certificate
representing such shares with a transfer endorsed thereon or delivered therewith
duly executed by the registered holder or by his attorney or successor duly
appointed, together with such reasonable assurances or evidence of signature,
identification and authority to transfer as the board may from time to time

8.          NON-RECOGNITION OF TRUSTS

            Subject to the provision of the Act, the Corporation may treat as
the absolute owner of a share the person in whose name the share is registered
in the securities register as if that person had full legal capacity and
authority to exercise all rights of ownership, irrespective of any indication to
the contrary through knowledge or notice or description in the Corporation's
records or on the share certificate.

8.          SHARE CERTIFICATES

            Every holder of one or more shares of the Corporation shall be

written acknowledgement of his right to obtain a share certificate, stating the
name of the person to whom the certificate or acknowledgement was issued, and
the number and class or series of shares held by him as shown on the securities
register. Share certificates and acknowledgments of a shareholder's right to a
share certificate, shall subject to the Act, be in such form as the board shall

certificates which are not valid unless countersigned by or on behalf of a
transfer agent and/or registrar, the signatures of both signing officers, may be
printed or mechanically reproduced in facsimile upon share certificates and
every such facsimile signature shall for all purposes be deemed to be the
signature of the officer whose
<PAGE>
signature it reproduces and shall be binding upon the corporation. A share
certificate executed as aforesaid shall be valid notwithstanding that one or
both of the officers whose facsimile signatures appears thereon no longer holds
office at the date of issue of the certificate.

8.          REPLACEMENT OF SHARE CERTIFICATE

            The board or any officer or agent designated by the board may in its
or his discretion direct the issue of a new share certificate in lieu of and
upon cancellation of a share certificate that has been mutilated or in
substitution for a share certificate claimed to have been lost, destroyed or
wrongfully taken on payment of a reasonable fee, and on such terms as to
indemnity, reimbursement of expenses and evidence of loss and of title as the
board may from time to time prescribe, whether generally or in any particular
case.

8.          JOINT SHAREHOLDERS

            If two or more persons are registered as joint holders of any share,
the Corporation shall not be bound to issue more than one certificate in respect
thereof, and delivery of such certificate to one of such persons shall be
sufficient delivery to all of them. Any one of such person may give effectual
receipts for the certificate issued in respect thereof or for any dividend,
bonus, return of capital or other money payable or warrant issuable in respect
of such share.

8.10        DECEASED SHAREHOLDER

            In the event of the death of a holder, or of one of the joint
holders, of any share, the Corporation shall not be required to make any entry
in the securities register in respect thereof or to make payment of any
dividends thereon except upon production of all such documents as may be
required by law and upon compliance with the reasonable requirements of the
Corporation and its transfer agents.

8.11        LIEN FOR INDEBTEDNESS

            If the articles provide that the Corporation has a lien on shares
registered in the name of a shareholder or his legal representative for a debt
of that shareholder to the Corporation, such lien may be enforced, subject to
the Act and to any other provision of the articles by the sale of the shares
thereby affected or by any other action, suit, remedy or proceeding authorized
or permitted by law or by equity and, pending such enforcement, the Corporation
may refuse to register a transfer of the whole or any part of such shares.

mailed by prepaid ordinary mail to such registered holder at his recorded
address, unless such holder otherwise directs. In the case of joint holders the
cheque shall, unless such joint holders otherwise direct, be made payable to the
order of all such joint holders and mailed to them at their recorded address.
The mailing of such cheque as aforesaid, unless the same is not paid on due
presentation, shall satisfy and discharge the liability for the dividend to the
extent of the sum represented thereby plus the amount of any tax which the
Corporation is required to and does withhold.

            In the event of non-receipt of any dividend cheque by the person to

            The board may fix in advance a date, preceding by not more than 50
days the date for the payment of any dividend or the date for the issue of any
warrant or other evidence of right to subscribe for securities of the
Corporation, as a record date for the determination of the persons entitled to
receive payment of such dividend or to receive the right to subscribe for such
securities, provided that if the Corporation is a distributing corporation,
notice of any such record date is given, not less than seven days before such
record date, in the manner provided in the Act. Where no record date is fixed in
advance as aforesaid, the record date for the determination of the persons
entitled to receive payment of any dividend or to receive the right to subscribe

            A meeting of shareholders may be held without notice at any time and
place permitted by the Act:

            (a)   if all shareholders entitled to vote thereat are present in
                  person or represented or if those not present or represented
                  waive notice of or otherwise consent to such meeting being
                  held, and

            (b)   if the auditors and the directors are present or waive notice
                  of or otherwise consent to such meeting being held;

so long as such shareholders, auditors or directors present are not attending
for the express purpose of objecting to the transaction of any business on the
grounds that the meeting is not lawfully called. At such a meeting any business
may be transacted which the Corporation at a meeting of Shareholders may
transact. If the meeting is held at a place outside the Yukon Territory,
shareholders not present or represented by proxy, but who have waived notice of
or otherwise consented to such meeting, shall also be deemed to have consented
to the meeting being held at such place.

10.08       CHAIRMAN AND SECRETARY

            The chairman of any meeting of shareholders shall be the president,
or in his absence, a vice-president who is a shareholder. If no such officer is

at the meeting. Any other person may be admitted only on the invitation of the
Chairman of the meeting or with consent of the meeting.

10.10       QUORUM

            A quorum for the transaction of business at any meeting of
shareholders shall be at least two persons present in person, each being a
shareholder entitled to vote thereat or a duly
<PAGE>
appointed proxy or representative for an absent shareholder so entitled, and
representing in the aggregate not less than 5% of the outstanding shares of the
Corporation carrying voting rights at the meeting. If a quorum is present at the
opening of any meeting of shareholders, the shareholders present or represented
may proceed with the business of the meeting notwithstanding that a quorum is
not present throughout the meeting. If a quorum is not present at the opening of
any meeting of shareholders, the shareholders present or represented may adjourn
the meeting to a fixed time and place but may not transact any other business
until a quorum is present.

10.11       RIGHT TO VOTE

            Every person named in the list referred to in Clause 10.06 shall be
entitled to vote the shares shown thereon opposite his name at the meeting to
which such list relates, except to the extent that:

            (a)   where the Corporation has fixed a record date in respect of
                  such meeting, such person has transferred any of his shares
                  after such record date or, where the Corporation has not fixed
                  a record date in respect of such meeting, such person has
                  transferred any of his shares after the date on which such
                  list is prepared, and

            (b)   the transferee, having produced properly endorsed certificates
                  evidencing such shares or having otherwise established that he
                  owns such shares, has demanded not later than 10 days before
                  the meeting that his name be included in such list.

In any such excepted case the transferee shall be entitled to vote the
transferred shares at such meeting. If the Corporation is not required to
prepare a list under Clause 10.06, subject to the provisions of the Act and this
by-law as to proxies and representative, at any meeting of shareholders every
person shall be entitled to vote at the meeting who at the time is entered in
the securities register as the holder of one or more shares carrying the right
to vote at such meeting.

10.12       PROXIES AND REPRESENTATIVES

            Every shareholder entitled to vote at a meeting of shareholders may
appoint a proxyholder, or one or more alternate proxyholders, who need not be
shareholders, to attend and act at the meeting in the manner and to the extent
authorized and with the authority conferred by the proxy. A proxy shall be in
writing executed by the shareholder or his attorney and shall conform with the
requirements of the Act. Alternately, every such shareholder which is a body
corporate or association may
<PAGE>
authorize by resolution of its directors or governing body an individual, who
need not be a shareholder, to represent it at a meeting of shareholders and such
individual may exercise on the shareholders behalf all the powers it could
exercise if it were an individual shareholder. The authority of such an
individual shall be established by depositing with the Corporation a certified
copy of such resolution, or in such other manner as may be satisfactory to the
secretary of the Corporation or the chairman of the meeting.

10.13       TIME FOR DEPOSIT OF PROXIES

            The board may specify in a notice calling a meeting of the
shareholders a time, preceding, the time of such meeting or an adjournment
thereof by not more than 48 hours exclusive of non-business days, before which

jointly held by them.

10.15       VOTES TO GOVERN

            At any meeting of shareholders every question shall, unless
otherwise required by the articles or by-laws, be determined by the majority of

show of hands or upon a poll, the chairman of the meeting shall not be entitled
to a second or casting vote.

who is present and entitled to vote shall have one vote. Whenever a vote by show

<PAGE>
to that effect in the minutes of the meeting shall be prima faci evidence of the
fact without proof of the number or proportion of the votes recorded in favour
of or against any resolution or other proceeding in respect of the said
question, and the result of the vote so taken shall be the decision of the
shareholders upon the said question.

            On any question proposed for consideration at a meeting of
shareholders, any shareholder or proxyholder entitled to vote at the meeting may

any vote by show of hands. A ballot so required or demanded shall be taken in
such manner as the chairman shall direct. A requirement or demand for a ballot
may be withdrawn at any time prior to the taking of the ballot. If a ballot is
taken each person present shall be entitled, in respect of the shares which he
is entitled to vote at a meeting upon the question, to that number of votes
provided by the Act or the articles, and the result of the ballot so taken shall
be the decision of the shareholders upon the said question.

10.18       ADMISSION OR REJECTION OF A VOTE

            In case of any dispute as to the admission or rejection of a vote,
the chairman shall determine the same and such determination made in good faith
shall be final and conclusive.

10.19       ADJOURNMENT

            If a meeting of the shareholders is adjourned by one or more
adjournments for an aggregate of less than 30 days, it shall not be necessary to
give notice of the adjourned meeting, other than by announcement at the time of
an adjournment. If a meeting of shareholders is adjourned by one or more

meeting shall be given as for an original meeting.

10.20       RESOLUTION IN WRITING

            A resolution in writing signed by all the shareholders entitled to
vote on that resolution at a meeting of shareholders is as valid as if it had
been passed at a meeting of the shareholders.

10.21       ONLY ONE SHAREHOLDER

            Where the Corporation has only one shareholder, or only one holder
of any class or series of shares, the shareholder present in person or by proxy

conferred by the Act, determine whether and to what extent and at what time and
place and under what circumstances or regulations the documents, books and

inspection of shareholders and no shareholder shall have any right to inspect
any document or book or register or accounting records of the Corporation except
as conferred by statute or authorized by the board of Directors or by a
resolution of the shareholders.

given (which term includes sent, delivered or served) pursuant to the Act, the
regulations thereunder, the articles, the by-laws or otherwise to a shareholder,
director, officer, auditor or member of a committee of the board shall be
sufficiently given if delivered personally to the person to whom it is to be
given or if delivered to his recorded address or if mailed to him at his
recorded address by prepaid ordinary or air mail or if sent to him at his
recorded address by any means of prepaid transmitted or recorded communication
including facsimile transmission. A notice so delivered shall be deemed to have
been given when it is delivered personally or to the recorded address as
aforesaid; a notice so mailed shall be deemed to have been given when dispatched
or delivered to the appropriate communication company or agency or its
representative for dispatch. The secretary may change or cause to be changed the
recorded address of any shareholder, director, officer, auditor or member of a

reliable.

13.02       NOTICE TO JOINT SHAREHOLDERS

            If two or more persons are registered as joint holders of any share,
any notice shall be addressed to all of such joint holders but notice to one of
such persons shall be sufficient notice to all of them.

13.03       COMPUTATION OF TIME

            In computing the date when notice must be given under any provision
requiring a specified number of days' notice of any meeting or other event, the
date of giving the notice shall be excluded and the date of the meeting or other
event shall be included.

13.04       UNDELIVERED NOTICES

            If notices given to a shareholder pursuant to Clause 13.01 are
returned on three consecutive occasions because he cannot be found, the
Corporation shall not be required to give
<PAGE>
any further notices to such shareholder until he informs the Corporation in
writing of his new address.

13.05       OMISSIONS AND ERRORS

            The accidental omission to give any notice to any shareholder,
director, officer, auditor or member of a committee of the board or the

affecting the substance thereof shall not invalidate any action taken at the
meeting held pursuant to such notice or otherwise founded thereon.

13.06       PERSONS ENTITLED BY DEATH OR OPERATION OF LAW

            Every person who, by operation of law, transfer, death of a
shareholder or any other means whatsoever shall become entitled to any share,
shall be bound by every notice in respect of such share which shall have been
duly given to the shareholder from whom he derives his title to such share prior
to his name and address being entered on the securities register (whether such
notice was given before or after happening of the event upon which he became so
entitled) and prior to his furnishing to the Corporation the proof of authority
or evidence of his entitlement prescribed by the Act.

13.07       WAIVER OF NOTICE

            Any shareholder (or his duly appointed proxyholder), director,
officer, auditor or member of a committee of the board may at any time waive any
notice, or waive or abridge the time for any notice, required to be given to him
under any provision of the Act, the regulations thereunder, the articles, the
by-laws or otherwise and such waiver or abridgement shall cure any default in
the giving or in the time of such notice, as the case may be. Any such waiver or
abridgement shall be in writing except a waiver or notice of a meeting of
shareholders or of the board which may be given in any manner.

CERTIFICATE NO. _________               one such warrant entitling the holder to
                                        purchase 1 Common Share at a price of
                                        U.S. $18.50 per Common Share on or
                                        before October 15, 1997.

THIS IS TO CERTIFY THAT _____________________________________ (herein called the
"holder") is entitled to acquire in the manner herein provided, subject to the
restrictions herein contained, during the period commencing on the date hereof
and ending at 5:00 p.m. (Vancouver time) on October 15, 1997 (the "Expiry
Date"), the number of fully paid and non-assessable common shares ("Common
Shares") without nominal or par value of Seven Seas Petroleum Inc. ("the
Corporation") as set forth above.

Such right to purchase Common Shares may only be exercised by the holder hereof
within the time hereinbefore set out by:
<PAGE>
      (a)   duly completing in the manner indicated and executing the Exercise
            Form attached hereto; and

      (b)   surrendering this Class B Warrant Certificate to Montreal Trust
            Company of Canada (the "Trustee") at the principal office of the
            Trustee in the City of Vancouver, British Columbia; and

      (c)   payment by cash or certified cheque or money order in lawful monies
            of the United States of America, payable to or to the order of the
            Corporation in the amount of EIGHTEEN DOLLARS AND FIFTY CENTS
            ($18.50), for each Common Share to be purchased until the Expiry
            Date (the "Exercise Price") at the principal office of the Trustee
            in the City of Vancouver, British Columbia.

These Class B Warrants shall be deemed to be so surrendered only upon personal
delivery thereof or, if sent by post or other means of transmission, upon actual
receipt thereof by the Trustee at the office referred to above.

Upon such surrender, the person or persons in whose name or names the Common
Shares issuable upon exercise of the Class B Warrants are to be issued shall be
deemed for all purposes (except as provided in the Indenture hereinafter
referred to) the holder or holders of record of such Common Shares and the
Corporation covenants that it will (subject to the provisions of the Indenture)
cause a certificate or certificates representing such Common Shares to be
delivered or mailed to such person or persons at the address or addresses
specified in such Exercise Form.

The registered holder of these Class B Warrants may acquire any lesser number of
Common Shares than the number of Common Shares which may be acquired for the
Class B Warrants represented by this Class B Warrant Certificate and in such
event shall be entitled to receive a new Class B Warrant Certificate in respect
of the balance of the Common Shares which may be acquired.

To the extent that the Class B Warrants represented by this Class B Warrant
Certificate confer the right to acquire a fraction of a Common Share, such right
may be exercised in respect of such fraction only in combination with an
additional Class B Warrant or Class B Warrants which in the aggregate entitle
the holder to acquire a whole number of Common Shares. No fractional Common
Shares will be issued.

The Class B Warrants represented by this Class B Warrant Certificate are issued
under and pursuant to a Class B Warrant indenture (herein called the
"Indenture") made as of October 15, 1996, between the Corporation and the
Trustee (which expression shall include any successor trustee appointed under
the Indenture), to which Indenture and any instruments supplemental thereto
reference is hereby made for a full description of the rights of the holders of
the Class B Warrants and the terms and conditions upon which such Class B
Warrants are, or are to be, issued and held, all to the same effect as if the
provisions of the Indenture and all instruments supplemental thereto were herein
set forth, and to all of which provisions the holder of these Class B Warrants
by acceptance hereof assents.
<PAGE>
In the event of any alteration of the Common Shares, including any subdivision,
consolidation or reclassification, and in the event of any form of
reorganization of the Corporation, including any amalgamation, merger or
arrangement, an adjustment shall be made to the terms of the Class B Warrants
such that the holders thereof, upon exercise of any Class B Warrants following
the completion of any of the above noted events, will be entitled to receive the
same number and kind of securities that they would have been entitled to receive
had they exercised their Class B Warrants immediately prior to such event.

The registered holder of this Class B Warrant Certificate may at any time prior
to the Expiry Date of the Class B Warrants, upon surrender hereof to the Trustee
at its principal office in the City of Vancouver, British Columbia and payment
of the charges provided for in the Indenture, exchange this Class B Warrant
Certificate for other Class B Warrant Certificates evidencing Class B Warrants
entitling the holder to acquire in the aggregate the same number of Common
Shares as may be acquired under this Class B Warrant Certificate.

The holding of the Class B Warrants evidenced by this Class B Warrant
Certificate shall not constitute the holder hereof a shareholder of the
Corporation or entitle such holder to any right or interest in respect thereof
except as herein and in the Indenture expressly provided.

The Indenture contains provisions making binding upon all holders of Class B
Warrant Certificates outstanding thereunder resolutions passed at meetings of
such holders held in accordance with such provisions and instruments in writing
signed by the holders of Class B Warrants entitled to acquire a specified
majority of the Common Shares which may be acquired pursuant to all then
outstanding Class B Warrant Certificates.

The Class B Warrants evidenced by this Class B Warrant Certificate may not be
transferred or assigned.

This Class B Warrant Certificate shall not be valid for any purpose whatever
unless and until it has been countersigned by or on behalf of the Trustee.

Time shall be of the essence hereof.
<PAGE>
Words and phrases defined in the Indenture where used in this Class B Warrant
Certificate shall be given the meanings ascribed thereto in the Indenture unless
otherwise defined herein.

IN WITNESS WHEREOF the Corporation has caused this Class B Warrant Certificate
to be signed by its duly authorized officers effective as of October 15, 1996.

2.03        WARRANTHOLDER NOT A SHAREHOLDER

            Except as provided for in subsection 5.02(g), nothing in this
Indenture or in the holding of a Class B Warrant itself evidenced by a Warrant
Certificate or otherwise, shall confer or be construed as conferring upon a

            the Trustee in the form set out in Schedule "A" hereto, and such
            countersignature by the Trustee upon any Warrant Certificate shall
            be conclusive evidence as against the Corporation that the
            Warrant Certificate so certified has been duly issued hereunder
            and that the holder is entitled to the benefits hereof.

      (b)   The countersignature of the Trustee on Warrant Certificates issued
            hereunder shall not be construed as a representation or warranty by
            the Trustee as to the validity of this Indenture or the Warrant
            Certificates (except the due countersigning thereof) and the Trustee
            shall in no respect be liable or answerable for the use

      (a)   In case any of the Warrant Certificates shall become mutilated or
            be lost, destroyed or stolen, the Corporation, subject to applicable
            law, shall issue and thereupon the Trustee shall certify and
            deliver, a new Warrant Certificate of like tenor as the one
            mutilated, lost, destroyed or stolen in exchange for and in place
            of and upon cancellation of such mutilated Warrant Certificate, or
            in lieu of and in substitution for such lost, destroyed or stolen
            Warrant Certificate, and the substituted Warrant Certificate shall
            be in a form approved by the Trustee and shall be entitled to the
            benefits hereof and shall rank equally in accordance with its terms
            and all other Warrant Certificates issued or to be issued
            hereunder.

      (b)   The applicant for the issue of a new Warrant Certificate pursuant to
            this Section 2.07 shall bear the cost of the issue thereof and in
            case of loss, destruction or theft shall, as a condition precedent
            to the issue thereof, furnish to the Corporation and to the Trustee
            such evidence of ownership and of the loss, destruction or theft of
            the Warrant Certificate so lost, destroyed or stolen as shall be

            discretion, and such applicant may also be required to furnish an
            indemnity or security in amount and form satisfactory to the
            Corporation and the Trustee in their discretion and shall pay the
            reasonable charges of the Corporation and the Trustee in connection
            therewith.

            Warrant Certificate or Warrant Certificates entitling the holder
            thereto to acquire in the aggregate the same number of Common Shares
            as may be acquired under the Warrant Certificate or Warrant

Corporation and the Trustee with respect to such Class B Warrants and neither
the Corporation nor the Trustee shall be bound to inquire into the title of any
such holder.

3.01        METHOD OF EXERCISE OF CLASS B WARRANTS

      (a)   The holder of any Class B Warrant may exercise the right thereby
            conferred on such holder to acquire Common Shares by
            surrendering, prior to the Time of Expiry, to the Warrant Agency

            A Warrant Certificate with the duly completed and executed exercise
            form referred to in this subsection 3.01(a) shall be

                  required to issue or deliver certificates evidencing Common
                  Shares unless or until such Warrantholder shall have paid to
                  the Corporation, or the Warrant Agency on behalf of the
                  Corporation, the amount of such tax or shall have
                  established to the satisfaction of the Corporation that such
                  tax has been paid or that no tax is due;

                  be guaranteed by a Canadian chartered bank or trust company or
                  by a member of the Vancouver, Toronto, Montreal or New York

            Common Shares will not be issued to a person whose address is
            in, or whom the Corporation or the Trustee has reason to believe

            corporation or other entity organized or incorporated under the laws
            of the United States during the 40 day period commencing on the
            exercise of such Class B Warrants except pursuant to a registration
            statement under the UNITED STATES SECURITIES ACT OF 1933 and in
            compliance with applicable securities laws of various States or

            change of the Warrant Agency.

3.02        EFFECT OF EXERCISE OF CLASS B WARRANTS

      (a)   Upon compliance by the holder of any Warrant Certificate with the
            provisions of Section 3.01, and subject to Section 3.03, the Common
            Shares subscribed for shall be deemed to have been issued and the
            person or persons to whom such Common Shares are to be issued shall
            be deemed to have become the holder or holders of record of such
            Common Shares on the Exercise Date unless the transfer registers of
            the Corporation shall be closed on such date, in which case the
            Common Shares subscribed for shall be deemed to have been issued,
            and such person or persons deemed to have become the holder or
            holders of record of such Common Shares, on the date on which such
            transfer registers are reopened.

            Warrant as aforesaid, the Corporation shall cause to be mailed to
            the person or persons in whose name or names the Common Shares so
            subscribed for have been issued, as specified in the subscription,
            at the address specified in such subscription or, if so specified in
            such subscription, cause to be delivered to such person or persons
            at the Warrant Agency where such Warrant Certificate was
            surrendered, a certificate or certificates for the appropriate

3.03        PARTIAL EXERCISE OF CLASS B WARRANTS; FRACTIONS

      (a)   The holder of any Warrant Certificate(s) may acquire a number of
            Common Shares less than the number which the holder is entitled to
            acquire pursuant to the surrendered Warrant Certificate(s) provided
            that, in no event shall fractional Common Shares be issued with
            regard to Class B Warrants exercised. In the event of any
            acquisition of a number of Common Shares less than the number which
            the holder is entitled to acquire, the holder of the Warrant
            Certificate(s) upon exercise thereof shall, in addition, be entitled
            to receive, without charge therefor, a new Warrant Certificate(s) in
            respect of the balance of the Common Shares which such holder was
            entitled to acquire pursuant to the surrendered Warrant
            Certificate(s) and which were not then acquired.

      (b)   Notwithstanding anything herein contained including any
            adjustment provided for in Article IV, the Corporation shall not be
            required, upon the exercise of any Class B Warrants, to issue
            fractions of Common Shares or to distribute certificates which
            evidence fractional Common Shares.  In lieu of fractional Common
            Shares, there shall be paid to the holder upon surrender of
            Warrant Certificate(s) for exercise of Class B Warrants pursuant
            to Section 3.01, within ten Business Days after surrender, an
            amount in lawful money of Canada equal to the then current
            market value of such fractional interest calculated on the basis of
            the closing price of the Common Shares on The Toronto Stock
            Exchange (or such other stock exchange or electronic trading
            facility upon which the Common Shares are then listed) on the
            Trading Day immediately prior to the Exercise Date.

3.04        EXPIRATION OF CLASS B WARRANTS

            After the Time of Expiry, all rights under any Class B Warrant in
respect of which the right of subscription and acquisition herein and therein
provided for shall not theretofore have been exercised in accordance herewith
and therewith shall wholly cease and terminate and such Class B Warrant shall be
void and of no effect.

3.05        CANCELLATION OF SURRENDERED CLASS B WARRANTS

            All Warrant Certificates surrendered to the Warrant Agency pursuant
to Sections 2.07, 2.08, 3.01 and 5.01 shall be returned to the Trustee for
cancellation and, after the expiry of any period of retention prescribed by law,
destroyed by the Trustee and the Trustee shall furnish the Corporation with a
destruction certificate identifying the Warrant Certificates so destroyed and
the number of Class B Warrants

evidenced thereby and the number of Common Shares which could have been acquired
pursuant to each destroyed Warrant Certificate.

3.06        ACCOUNTING AND RECORDING

      (a)   The Trustee shall promptly account to the Corporation with respect
            to Class B Warrants exercised. Any securities or other instruments,
            from time to time received by the Trustee shall be received in trust
            for, and shall be segregated and kept apart by the Trustee in trust
            for, the Corporation.

      (b)   The Trustee shall record the particulars of Class B Warrants
            exercised which shall include the names and addresses of the persons
            who become holders of Common Shares on exercise and the Exercise
            Date. Within five Business Days of each Exercise Date, the Trustee
            shall provide such particulars in writing to the Corporation.

                                  ARTICLE IV
                     ADJUSTMENT OF NUMBER OF COMMON SHARES

4.01        ADJUSTMENT OF NUMBER OF COMMON SHARES

            The acquisition rights in effect at any date attaching to the Class
B Warrants shall be subject to adjustment from time to time as follows:

      (a)   if and whenever at any time from the date hereof and prior to the
            Time of Expiry, the Corporation shall:

            (i)   subdivide, redivide or change its outstanding Common
                  Shares into a greater number of shares; or

            (ii)  reduce, combine or consolidate its outstanding Common
                  Shares into a smaller number of shares,

            the number of Common Shares obtainable under each Class B Warrant
            shall each be adjusted immediately after the effective date of the
            events referred to in (i) and (ii) above by multiplying the number
            of Common Shares theretofore obtainable on the exercise of the Class
            B Warrants by a fraction of which the numerator shall be the total
            number of Common Shares outstanding immediately after such date and
            the denominator shall be the total number of Common Shares
            outstanding immediately
<PAGE>
                                   - 13 -

            prior to such date.  Such adjustment shall be made successively
            whenever any event referred to in this subsection shall occur;

      (b)   if and whenever at any time from the date hereof and prior to the
            Time of Expiry, there is a reclassification or redesignation of the
            Common Shares or a capital reorganization of the Corporation other
            than as described in subsection 4.01(a) or a consolidation,
            arrangement, amalgamation or merger of the Corporation with or into
            any other body corporate, trust, partnership or other entity, or a
            sale or conveyance of the property and assets of the Corporation as
            an entirety or substantially as an entirety to any other body
            corporate, trust, partnership or other entity, any Warrantholder who
            has not exercised his right of acquisition prior to the effective
            date of such reclassification, redesignation, capital
            reorganization, consolidation, arrangement, amalgamation, merger,
            sale or conveyance, upon the exercise of such right thereafter,
            shall be entitled to receive and shall accept, in lieu of the number
            of Common Shares then sought to be acquired by him, the number of
            shares or other securities or property of the Corporation or of the
            body corporate, trust, partnership or other entity resulting from
            such merger, amalgamation, arrangement, or consolidation, or to
            which such sale or conveyance may be made, as the case may be, that
            such Warrantholder would have been entitled to receive on such
            reclassification, redesignation, capital reorganization,
            consolidation, arrangement, amalgamation, merger, sale or
            conveyance, if, on the record date or the effective date thereof, as
            the case may be, the Warrantholder had been the registered holder of
            the number of Common Shares receivable upon the exercise of Class B
            Warrants then held. If determined appropriate by the Trustee to give
            effect to or to evidence the provisions of this subsection 4.01(b),
            the Corporation, its successor, or such purchasing body corporate,
            partnership, trust or other entity, as the case may be, shall, prior
            to or contemporaneously with any such reclassification,
            redesignation, capital reorganization, consolidation, amalgamation,
            arrangement, merger, sale or conveyance, enter into an indenture
            which shall provide, to the extent possible, for the application of
            the provisions set forth in this Indenture with respect to the
            rights and interests thereafter of the Warrantholders to the end
            that the provisions set forth in this Indenture shall thereafter
            correspondingly be made applicable, as nearly as may reasonably be,
            with respect to any shares, other securities or property to which a
            Warrantholder is entitled on the exercise of his acquisition rights
            thereafter. Any indenture entered into between the Corporation and
            the Trustee pursuant to the provision of this
<PAGE>
                                   - 14 -

            subsection 4.01(b) shall be a supplemental indenture entered into
            pursuant to the provisions of Article VIII hereof. Any indenture
            entered into between the Corporation, any successor to the
            Corporation or such purchasing body corporate, partnership, trust or
            other entity and the Trustee shall provide for adjustments which
            shall be as nearly equivalent as may be practicable to the
            adjustments provided in this Section 4.01 and which shall apply to
            successive reclassifications, redesignations, capital
            reorganizations, consolidations, arrangements, amalgamations,
            mergers, sales or conveyances;

      (c)   if and whenever at any time prior to the Time of Expiry, the
            Corporation shall:

            (i)   subdivide the outstanding Common Shares into a greater
                  number of Common Shares,

            (ii)  consolidate the outstanding Common Shares into a lesser
                  number of Common Shares, or

            (iii) issue Common Shares by way of a stock dividend (other than the
                  issue of Common Shares to holders of Common Shares as a stock
                  dividend in lieu of a cash dividend paid in the ordinary
                  course),

            the Exercise Price shall, on the effective date of such subdivision
            or consolidation or on the record date of such subdivision or stock
            dividend, as the case may be, be adjusted to that amount which is in
            the same proportion to the Exercise Price in effect immediately
            prior to such subdivision, consolidation or stock dividend, as the
            number of outstanding Common Shares after giving effect to such
            subdivision, consolidation or stock dividend bears to the number of
            outstanding Common Shares after giving effect such subdivision,
            consolidation or stock dividend. Such adjustment shall be made
            successively whenever any event referred to in this subsection (1)
            shall occur; and any such issue of Common Shares by way of a stock
            dividend shall be deemed to have been made on the record date for
            the stock dividend for the purpose of calculating the number of
            outstanding Common Shares under subsections (d) and (e) of this
            Section 4.01;

      (d)   if and whenever at any time prior to the Time of Expiry, the
            Corporation shall fix a record date for the issuance of rights,
            options or warrants to all or substantially all the holders of the
            outstanding Common Shares entitling them to subscribe for or
<PAGE>
                                   - 15 -

            purchase Common Shares, or securities convertible into Common Shares
            at a price per share or having a conversion or exchange price per
            share less than 95% of the Current Market Price (as defined in
            subsection (f) of this Section 4.01), on such record date, the
            Exercise Price shall be adjusted immediately after such record date
            so that it shall equal the price determined by multiplying the
            Exercise Price in effect on such record date by a fraction of which
            the numerator shall be the total number of Common Shares outstanding
            at such record date plus a number of Common Shares equal to the
            number arrived at by dividing the aggregate price of the total
            number of additional Common Shares offered for subscription or
            purchase, or into which the convertible securities so offered are
            convertible, or the aggregate conversion or exchange price of the
            convertible securities so offered, by such Current Market Price, and
            of which the denominator shall be the total number of Common Shares
            outstanding on such record date plus the total number of additional
            Common Shares offered for subscription or purchase or into which the
            convertible Securities so offered are convertible; Common Shares
            owned by or held for the account of the Corporation or any
            subsidiary of the Corporation shall be deemed not to be outstanding
            for the purpose of any such computation; such adjustment shall be
            made successively whenever such a record date is fixed; to the
            extent that any rights, options or warrants are not so issued or any
            such rights, options or warrants are not exercised prior to the
            expiration thereof, the Exercise Price shall then be readjusted to
            the Exercise Price which would then be in effect if such record data
            had not been fixed or to the Exercise Price which would then be in
            effect based upon the number of Common Shares, or securities
            convertible into Common Shares, actually issued upon the exercise of
            such rights, options or warrants, as the case may be;

      (e)   if and whenever at any time prior to the Time of Expiry, the
            Corporation shall fix a record date for the making of a distribution
            to all or substantially all the holders of its outstanding Common
            Shares of:

            (i)   shares of any class other than Common Shares whether of the
                  Corporation or any other corporation (other than shares
                  distributed to holders of Common Shares as a stock dividend in
                  lieu of a cash dividend paid in the ordinary course), or

            (ii)  rights, options or warrants (other than those referred to in
                  subsection (d) of this Section 4.01), or
<PAGE>
                                   - 16 -

            (iii) evidences of its indebtedness, or

            (iv)  assets (other than cash dividends paid in the ordinary
                  course)

            then, in each such case, the Exercise Price shall be adjusted
            immediately after such record date so that it shall equal the price
            determined by multiplying the Exercise Price in effect on such
            record date by a fraction, of which the numerator shall be the total
            number of Common Shares outstanding on such record date multiplied
            by the Current Market Price on such record date, less the aggregate
            fair market value (as determined by the directors and approved by
            the Trustee) of such shares or rights, options or warrants or
            evidences of indebtedness or assets so distributed, and of which the
            denominator shall be the total number of Common Shares outstanding
            on such record date multiplied by such Current Market Price; Common
            Shares owned by or held for the account of the Corporation or any
            subsidiary of the Corporation shall be deemed not to be outstanding
            for the purpose of any such computation; such adjustment shall be
            made successively whenever such a record date is fixed; and to the
            extent that such distribution is not so made, the Exercise Price
            shall then be readjusted to the Exercise Price which would then be
            in effect if such record date had not been fixed or to the Exercise
            Price which would then be in effect based upon such shares or
            rights, options or warrants or evidences of indebtedness or assets
            actually distributed, as the case may be;

      (f)   for the purpose of any computation under subsections (d) or (e)
            of this Section 4.01, the "Current Market Price" at any date shall
            be the weighted average of the closing prices per share for
            Common Shares for any 30 consecutive trading days selected by
            the Corporation commencing not more than 45 trading days
            before such date on The Toronto Stock Exchange (or such other
            stock exchange or electronic trading facility on which the
            Common Shares shall then trade).  The weighted average price
            shall be determined by dividing the aggregate sale price or the
            average closing bid and ask prices of all such shares sold on the
            said exchange or facility during the said 30 consecutive trading
            days by the total number of such shares so sold;

      (g)   in any case in which this Article IV shall require that an
            adjustment shall become effective immediately after a record date
            for an event referred to herein, the Corporation may defer, until
            the occurrence of such event, issuing to the holder of any Class
<PAGE>
                                   - 17 -

            B Warrant exercised after such record date and before the occurrence
            of such event the additional Common Shares issuable upon such
            exercise by reason of the adjustment required by such event before
            giving effect to such adjustment; provided, however, that the
            Corporation shall deliver to such holder an appropriate instrument
            evidencing such holder's right to receive such additional Common
            Shares upon the occurrence of the event requiring such adjustment
            and the right to receive any distributions made on such additional
            Common Shares which may be acquired upon the exercise of Class B
            Warrants declared in favour of holders of record of Common Shares on
            and after the Exercise Date or such later date as such holder would,
            but for the provisions of this subsection (g), have become the
            holder of record of such additional Common Shares pursuant to
            Section 4.01; and

      (h)   the adjustments provided for in this Article IV in the number of
            Common Shares, Exercise Price and classes of securities which
            are to be received on the exercise of Class B Warrants, are
            cumulative.  After any adjustment pursuant to this Section 4.01,
            the terms "Common Shares" where used in this Indenture shall be
            interpreted to mean securities of any class or classes which, as a
            result of such adjustment and all prior adjustments pursuant to
            this Section 4.01, the Warrantholder is entitled to receive upon
            the exercise of his Class B Warrant, and the number of Common
            Shares indicated by any exercise made pursuant to a Class B
            Warrant shall be interpreted to mean the number of Common
            Shares or other property or securities a Warrantholder is entitled
            to receive, as a result of such adjustment and all prior adjustments
            pursuant to this Section 4.01, upon the full exercise of a Class B
            Warrant.

4.02        ENTITLEMENT TO COMMON SHARES ON EXERCISE OF CLASS B WARRANT

            All shares of any class, or other securities which a Warrantholder
is at the time in question entitled to receive on the exercise of his Class B
Warrant, whether or not as a result of adjustments made pursuant to this Section
shall, for the purposes of the interpretation of this Indenture, be deemed to be
shares and other securities which such Warrantholder is entitled to acquire
pursuant to such Class B Warrant.

4.03        DETERMINATION BY CORPORATION'S AUDITORS

            In the event of any question arising with respect to the adjustments
provided for in this Article IV such question shall be conclusively determined
by the Corporation's auditors who shall have access to all necessary records of
the Corporation, and such determination shall be binding upon the Corporation,
the Trustee, all Warrantholders and all other persons interested therein.

4.04        PROCEEDINGS PRIOR TO ANY ACTION REQUIRING ADJUSTMENT

            As a condition precedent to the taking of any action which would
require an adjustment in any of the acquisition rights pursuant to any of the
Class B Warrants, including the number of Common Shares which are to be received
upon the exercise thereof, the Corporation shall take any corporate action which
may, in the opinion of counsel, be necessary in order that the Corporation has
unissued and reserved in its authorized capital and may validly and legally
issue as fully paid and non-assessable all the shares which the holders of such
Class B Warrants are entitled to receive on the full exercise thereof in
accordance with the provisions hereof.

4.05        CERTIFICATE OF ADJUSTMENT

            The Corporation shall from time to time immediately after the
occurrence of any event which requires an adjustment or readjustment as provided
in Article IV, deliver a certificate of the Corporation to the Trustee
specifying the nature of the event requiring the same and the amount of the
adjustment necessitated thereby and setting forth in reasonable detail the
method of calculation and the facts upon which such calculation is based, which
certificate and the amount of the adjustment specified therein shall be verified
by the Trustee.

4.06        PROTECTION OF TRUSTEE

            The Trustee:

      (a)   shall not at any time be under any duty or responsibility to any
            Warrantholder to determine whether any facts exist which may require
            any adjustment contemplated by Section 4.01 or with respect to the
            nature or extent of any such adjustment when made, or with respect
            to the method employed in making the same;

      (b)   shall not be accountable with respect to the validity or value (or
            the kind or amount) of any Common Shares or of any shares or other
            securities or property which may at any time be issued or delivered
            upon the exercise of the rights attaching to any Class B Warrant;
<PAGE>
                                   - 19 -

      (c)   shall not be responsible for any failure of the Corporation to
            issue, transfer or deliver Common Shares or certificates for the
            same upon the surrender of any Class B Warrants for the purpose of
            the exercise of such rights or to comply with any of the covenants
            contained in this Article IV; and

      (d)   shall not incur any liability or responsibility whatever or be in
            any way responsible for the consequences of any breach on the part
            of the Corporation of any of the representations, warranties or
            covenants herein contained or of any acts of the agents or servants
            of the Corporation.

                                   ARTICLE V
                    RIGHTS OF THE CORPORATION AND COVENANTS

5.01        OPTIONAL PURCHASES BY THE CORPORATION

            The Corporation may from time to time purchase by private contract
or otherwise any of the Class B Warrants. Any such purchase shall be made at the
lowest price or prices at which, in the opinion of the directors, such Class B
Warrants are then obtainable, plus reasonable costs of purchase, and may be made
in such manner, from such persons and on such other terms as the Corporation, in
its sole discretion, may determine. The Warrant Certificate representing the
Class B Warrants purchased pursuant to this Section 5.01 shall forthwith be
delivered to and cancelled by the Trustee.

5.02        GENERAL COVENANTS

            The Corporation covenants with the Trustee that so long as any Class
B Warrants remain outstanding:

      (a)   it will reserve and keep available a sufficient number of Common
            Shares for the purpose of enabling it to satisfy its obligations to
            issue Common Shares upon the exercise of the Class B Warrants in the
            event that the Corporation does not have an unlimited number of
            Common Shares authorized;

      (b)   it will cause the Common Shares and the certificates representing
            the Common Shares from time to time acquired pursuant to the
            exercise of the Class B Warrants to be duly issued and delivered in
            accordance with the Warrant Certificates and the terms hereof;
<PAGE>
                                   - 20 -

      (c)   all Common Shares which shall be issued upon exercise of the right
            to acquire provided for herein and in the Warrant Certificates shall
            be fully paid and non-assessable;

      (d)   it will use its best efforts to maintain its corporate existence;

      (e)   it will use its best efforts to ensure that all Common Shares of the
            Corporation outstanding or issuable from time to time continue to be
            traded on the Canadian Dealing Network and/or such other exchange or
            electronic trading facility as satisfactory to the directors of the
            Corporation;

      (f)   it will make all requisite filings under applicable Canadian
            securities legislation including those necessary to remain a
            reporting issuer not in default in the province of British Columbia;

      (g)   if the Corporation pays a dividend or makes any other distribution
            in cash or property or securities of the Corporation (including
            rights, options or warrants to acquire Common Shares or
            securities convertible into or exchangeable for Common Shares
            and including evidences of its indebtedness) to Shareholders prior
            to the Expiry Date, the Corporation agrees that it will pay the
            same amount of such dividend or make the same distribution to
            the Warrantholders, as if they were holders of such number of
            Common Shares which such Warrantholders are entitled to
            acquire upon the exercise of the Class B Warrants.  The
            Corporation will mail a notice to each holder of Class B Warrants
            specifying the particulars of such payment or distribution within
            two (2) Business Days of such payment or distribution;

      (h)   generally, it will well and truly perform and carry out all of the

5.04        PERFORMANCE OF COVENANTS BY TRUSTEE

            If the Corporation shall fail to perform any of its covenants
contained in this Warrant Indenture, the Trustee may notify the Warrantholders

said covenants capable of being performed by it, but, subject to Section 9.02,
shall be under no obligation to perform said covenants or to notify the
Warrantholders of such performance by it. All sums expended or advanced by the
Trustee in so doing shall be repayable as provided in Section 5.03. No such
performance, expenditure or advance by the Trustee shall relieve the Corporation

herein contained.

                                  ARTICLE VI
                                  ENFORCEMENT

name to enforce each and all of the provisions herein contained for the benefit
of the Warrantholders.

6.02        IMMUNITY OF SHAREHOLDERS, ETC.

            The Trustee and, by the acceptance of the Warrant Certificates and

present or future shareholder, director, officer, employee or agent of the
Corporation or any successor corporation for the issue of the Common Shares
pursuant to any Class B Warrants or on any covenant, agreement, representation
or warranty by the Corporation herein or contained in the Warrant Certificates.

or any of the past, present or future officers, employees or agents of the
Corporation or any successor corporation, but only the property of the
Corporation or any successor corporation shall be bound in respect hereof.

            by extraordinary resolution as provided in Section 7.10) by
            requisition in writing to instruct the Trustee to waive any default
            hereunder and the Trustee shall thereupon waive the default upon

            requisition; or

      (b)   the Trustee shall have power to waive any default hereunder upon

            provision made therefor;

provided that no delay or omission of the Trustee or of the Warrantholders to
exercise any right or power accruing upon any default shall impair any such
right or power or shall be construed to be a waiver of any such default or
acquiescence therein and provided further that no act or omission either of the
Trustee or of the Warrantholders shall extend to or be taken in any manner
whatsoever to affect any subsequent default hereunder or the rights resulting
therefrom.

                                  ARTICLE VII

and upon being indemnified to its reasonable satisfaction by the Corporation or
by the Warrantholders signing such Warrantholders' Request against the costs
which may be incurred in connection with the calling, and holding of such
meeting, convene a meeting of the Warrantholders. In the event of the Trustee
failing to convene a meeting within seven days after receipt of such written
request of the Corporation or such Warrantholders' Request and indemnity given

            At least ten (10) days' prior notice of any meeting of
Warrantholders shall be given to the Warrantholders in the manner provided for
in Section 10.02 and a copy of such notice shall be sent by mail to the Trustee
(unless the meeting has been called by the Trustee) and to the Corporation
(unless the meeting has been called by the Corporation). Such notice shall state
the time when and the place where the meeting is to be held, shall state briefly
the general nature of the business to be transacted thereat and shall contain
such information as is reasonably necessary to enable the Warrantholders to make
a reasoned decision on the matter, but it shall not be necessary for any such
notice to set out the terms of any resolution to be proposed or any of the
provisions of this Article VII.

7.03        CHAIRMAN

            An individual (who need not be a Warrantholder) designated in
writing by the Trustee shall be chairman of the meeting and if no individual is
so designated, or if the individual so designated is not present within 15
minutes from the time fixed for the holding of the meeting, the Warrantholders

chairman.

7.04        QUORUM

            Subject to the provisions of Section 7.11, at any meeting of the

proxy and entitled to acquire at least 25% of the aggregate number of Common
Shares which could be acquired pursuant to all the then outstanding Class B
Warrants, provided that at least two persons entitled to vote thereat are
personally present. If a quorum of the Warrantholders shall not be present
within 30 minutes from the time fixed for holding any meeting, the meeting, if
summoned by the Warrantholders or on a Warrantholders' Request, shall be
dissolved; but in any other case the meeting shall be adjourned to the same day
in the next week (unless such day is not a Business Day, in which case it shall
be adjourned to the next following Business Day) at the same time and place and
no notice of the adjournment need be given. Any business may be brought before
or dealt with at an adjourned meeting which might have been dealt with at the
original meeting in accordance with the notice calling the same. No business
shall be transacted at any meeting unless a quorum be present at the
commencement of business. At the adjourned meeting the Warrantholders present in
person or by proxy shall form a quorum and may transact the business for which
the meeting was originally convened, notwithstanding that they may not be
entitled to acquire at least 25% of the aggregate number of Common Shares which
may be acquired pursuant to all then outstanding Class B Warrants.

7.05        POWER TO ADJOURN

            The chairman of any meeting at which a quorum of the Warrantholders
is present may, with the consent of the meeting, adjourn any such meeting, and
no notice of such adjournment need be given except such notice, if any, as the
meeting may prescribe.

7.06        SHOW OF HANDS

            Every question submitted to a meeting shall be decided in the first
place by a majority of the votes given on a show of hands except that votes on
an extraordinary resolution shall be given in the manner hereinafter provided.
At any such meeting, unless a poll is duly demanded as herein provided, a
declaration by the chairman that a resolution has been carried or carried
unanimously or by a particular majority or lost or not carried by a particular
majority shall be conclusive evidence of the fact.

7.07        POLL AND VOTING

            On every extraordinary resolution, and on any other question
submitted to a meeting and after a vote by show of hands when demanded by the
chairman or by one or more of the Warrantholders acting in person or by proxy
and entitled to acquire in the aggregate at least 5% of the aggregate number of
Common Shares which could be acquired pursuant to all the Class B Warrants then
outstanding, a poll shall be taken in such manner as the chairman shall direct.
Questions other than those required to be determined by extraordinary resolution
shall be decided by a majority of the votes cast on the poll.

            On a show of hands, every person who is present and entitled to
vote, whether as a Warrantholder or as proxy for one or more absent
Warrantholders, or both, shall have one vote. On a poll, each Warrantholder
present in person or represented by a proxy duly appointed by instrument in
writing shall be entitled to one vote in respect of each Common Share which he
is entitled to acquire pursuant to the Class B Warrant or Class B Warrants then
held or represented by him. A proxy need not be a Warrantholder. The chairman of
any meeting shall be entitled, both on a show of hands and on a poll, to vote in
respect of the Class B Warrants, if any, held or represented by him.

7.08        REGULATIONS

            The Trustee, or the Corporation with the approval of the Trustee,

<PAGE>
                                   - 25 -

      (a)   the setting of the record date for a meeting for the purpose of
            determining Warrantholders entitled to receive notice of and to
            vote at a meeting;

      (b)   the issue of voting certificates by any bank, trust company or
            other depository satisfactory to the Trustee stating that the
            Warrant Certificates specified therein have been deposited with it
            by a named person and will remain on deposit until after the
            meeting, which voting certificates shall entitle the persons named
            therein to be present and vote at any such meeting and at any
            adjournment thereof or to appoint a proxy or proxies to represent
            them and vote for them at any such meeting and at any
            adjournment thereof in the same manner and with the same effect
            as though the persons so named in such voting certificates were
            the actual bearers of the Warrant Certificates specified therein;

      (c)   the deposit of voting certificates and instruments appointing
            proxies at such place and time as the Trustee, the Corporation or
            the Warrantholders convening the meeting, as the case may be, may in

            or sent by other means of electronic transmission before the
            meeting to the Corporation or to the Trustee at the place where
            the same is to be held and for the voting of proxies so deposited
            as though the instruments themselves were produced at the
            meeting;

      (e)   the form of the instrument of proxy; and

      (f)   generally for the calling of meetings of Warrantholders and the
            conduct of business thereat.

            Any regulations so made shall be binding and effective and the votes
given in accordance therewith shall be valid and shall be counted. Save as such
regulations may provide, the only persons who shall be recognized at any meeting
as a Warrantholder, or be entitled to vote or be present at the meeting in
respect thereof (subject to Section 7.09), shall be Warrantholders or their
counsel, or proxies of Warrantholders.

7.11        MEANING OF EXTRAORDINARY RESOLUTION

      (a)   The expression "extraordinary resolution" when used in this
            Indenture means, subject as hereinafter provided in this
            Section 7.11 and in Section 7.14, a resolution proposed at a
            meeting of Warrantholders duly convened for that purpose and
            held in accordance with the provisions of this Article VII at which
            there are present in person or by proxy Warrantholders entitled to
            acquire at least 25% of the aggregate number of Common Shares
            which may be acquired pursuant to all the then outstanding Class

      (b)   If, at any meeting called for the purpose of passing an
            extraordinary resolution, Warrantholders entitled to acquire at

            may be acquired pursuant to all the then outstanding Class B
            Warrants are not present in person or by proxy within 30 minutes

            place of such adjourned meeting in the manner provided for in
            Section 10.02. Such notice shall state that at the adjourned meeting
            the Warrantholders present in person or by proxy did not form a

            Any one or more of the powers or any combination of the powers in
this Indenture stated to be exercisable by the Warrantholders by extraordinary
resolution or otherwise may be exercised from time to time and the exercise of
any one or more of such powers or any combination of powers from time to time
shall not be deemed to exhaust the right of the Warrantholders to exercise such
power or powers or combination of powers then or thereafter from time to time.

accordance with the provisions of this Article VII at a meeting of
Warrantholders shall be binding upon all the Warrantholders, whether present at
or absent from such meeting, and every instrument in writing signed by
Warrantholders in accordance with Section 7.14 shall be binding upon all the
Warrantholders, whether signatories thereto or not, and each and every

            or relief shall be or become operative or effective only if, in the
            opinion of the Trustee, based upon the advice of counsel, such
            modification or relief in no way prejudices any of the rights of the
            Warrantholders or of the Trustee, and provided further that the
            Trustee may in its sole discretion decline to enter into any such
            supplemental indenture which in its opinion, based upon the

            Trustee when the same shall become operative; and

      (g)   for any other purpose not inconsistent with the terms of this
            Indenture, including the correction or rectification of any
            ambiguities, defective or inconsistent provisions, errors, mistakes
            or omissions herein, provided that in the opinion of the Trustee,
            based upon the advice of counsel, the rights of the Trustee and of
            the Warrantholders are in no way prejudiced thereby.

8.02        SUCCESSOR CORPORATIONS

            In the case of the consolidation, amalgamation, merger or transfer
of the undertaking or assets of the Corporation as an entirety or substantially
as an entirety to another corporation ("successor corporation"), the successor
corporation resulting from such consolidation, amalgamation, merger or transfer
(if not the Corporation) shall expressly assume, by supplemental indenture
satisfactory in form to the Trustee and executed and delivered to the Trustee,
the due and punctual performance and observance of each and every covenant and
condition of this Indenture to be performed and observed by the Corporation.

                                  ARTICLE IX
                            CONCERNING THE TRUSTEE

9.01        TRUST INDENTURE LEGISLATION

      (a)   If and to the extent that any provision of this Indenture limits,
            qualifies or conflicts with a mandatory requirement of Applicable
            Legislation, such mandatory requirement shall prevail.

      (b)   The Corporation and the Trustee agree that each will, at all times
            in relation to this Indenture and any action to be taken hereunder,
            observe and comply with and be entitled to the benefits of
            Applicable Legislation.

9.02        RIGHTS AND DUTIES OF TRUSTEE

      (a)   In the exercise of the rights and duties prescribed or conferred by
            the terms of this Indenture, the Trustee shall exercise that degree
            of care, diligence and skill that a reasonably prudent trustee would
            exercise in comparable circumstances. No provision of this Indenture
            shall be construed to relieve the Trustee from liability for its own
            negligent action, its own negligent failure to act, or its own
            wilful misconduct or bad faith.

      (b)   The obligation of the Trustee to commence or continue any act,
            action or proceeding for the purpose of enforcing any rights of the
            Trustee or the Warrantholders hereunder shall be conditional upon
            the Warrantholders furnishing, when required by notice by the
            Trustee, sufficient funds to commence or to continue such act,
            action or proceeding and an indemnity reasonably satisfactory to
            the Trustee to protect and to hold harmless the Trustee against
            the costs, charges and expenses and liabilities to be incurred
            thereby and any loss and damage it may suffer by reason thereof.
<PAGE>
                                   - 32 -

            None of the provisions contained in this Indenture shall require the
            Trustee to expend or to risk its own funds or otherwise to incur
            financial liability in the performance of any of its duties or in
            the exercise of any of its rights or powers unless indemnified and
            funded as aforesaid.

      (c)   The Trustee may, before commencing or at any time during the
            continuance of any such act, action or proceeding, require the
            Warrantholders, at whose instance it is acting to deposit with the
            Trustee the Class B Warrants held by them, for which Class B
            Warrants the Trustee shall issue receipts.

      (d)   Every provision of this Indenture that by its terms relieves the
            Trustee of liability or entitles it to rely upon any evidence
            submitted to it is subject to the provisions of Applicable
            Legislation, of this Section 9.02 and of Section 9.03.

9.03        EVIDENCE, EXPERTS AND ADVISERS

      (a)   In addition to the reports, certificates, opinions and other
            evidence required by this Indenture, the Corporation shall furnish
            to the Trustee such additional evidence of compliance with any
            provision hereof, and in such form, as may be prescribed by
            Applicable Legislation or as the Trustee may reasonably require by
            written notice to the Corporation.

      (b)   In the exercise of its rights and duties hereunder, the Trustee may,
            if it is acting in good faith, rely as to the truth of the
            statements and the accuracy of the opinions expressed in statutory
            declarations, opinions, reports, written requests, consents, or
            orders of the Corporation, certificates of the Corporation or other
            evidence furnished to the Trustee pursuant to any provision hereof
            or of Applicable Legislation or pursuant to a request of the
            Trustee, provided that such evidence complies with Applicable
            Legislation and that the Trustee examines the same and determines
            that such evidence complies with the applicable requirements of this
            Indenture.

      (c)   Whenever it is provided in this Indenture or under Applicable
            Legislation that the Corporation shall deposit with the Trustee
            resolutions, certificates, reports, opinions, requests, orders or
            other documents, it is intended that the trust, accuracy and good
            faith on the effective date thereof and the facts and opinions
            stated in all such documents so deposited shall, in each and every
<PAGE>
                                   - 33 -

            such case, be conditions precedent to the right of the Corporation
            to have the Trustee take the action to be based thereon.

      (d)   Proof of the execution of an instrument in writing, including a
            Warrantholders' Request, by an Warrantholder may be made by the
            certificate of a notary public, or other officer with similar
            powers, that the person signing such instrument acknowledged to him
            the execution thereof, or by an affidavit of a witness to such
            execution or in any other manner which the Trustee may consider
            adequate.

      (e)   The Trustee may employ or retain such counsel, accountants,
            appraisers or other experts or advisers as it may reasonably
            require for the purpose of discharging its duties hereunder and
            may pay reasonable remuneration for all services so performed by
            any of them, without taxation of costs of any counsel, and shall
            not be responsible for any misconduct or negligence on the part
            of any such experts or advisers who have been appointed with
            due care by the Trustee.

9.04        DOCUMENTS, MONIES, ETC. HELD BY TRUSTEE

            Any securities, documents of title or other instruments that may at
any time be held by the Trustee subject to the trusts hereof may be placed in
the deposit vaults of the Trustee or of any Canadian chartered bank or deposited
for safekeeping with any such bank. Unless herein otherwise expressly provided,
any monies so held pending the application or withdrawal thereof under any
provisions of this Indenture may be deposited in the name of the Trustee in any
Canadian chartered bank at the rate of interest (if any) then current on similar
deposits or, with the consent of the Corporation, may be:

            (i)   deposited in the deposit department of the Trustee or any
                  other loan or trust company authorized to accept deposits
                  under the laws of Canada or a province thereof, or

            (ii)  invested in securities issued or guaranteed by the
                  Government of Canada or a province thereof or in
                  obligations maturing not more than one year from the date
                  of investment, of any Canadian chartered bank or loan or
                  trust company.  Unless the Corporation shall be in default
                  hereunder, all interest or other income received by the
                  Trustee in respect of such deposits and investments shall
                  belong to the Corporation.

9.05        ACTIONS BY TRUSTEE TO PROTECT INTEREST

            The Trustee shall have power to institute and to maintain such
actions and proceedings as it may consider necessary or expedient to preserve,
protect or enforce its interests and the interests of the Warrantholders.

9.06        TRUSTEE NOT REQUIRED TO GIVE SECURITY

            The Trustee shall not be required to give any bond or security in
respect of the execution of the trusts and powers of this Indenture or otherwise
in respect of the premises.

9.07        PROTECTION OF TRUSTEE

            By way of supplement to the provisions of any law for the time being
relating to Trustees it is expressly declared and agreed as follows:

      (a)   the Trustee shall not be liable for or by reason of any statements
            of fact or recitals in this Indenture or in the Warrant Certificates
            (except the representation contained in Section 9.09 or in the
            signature of the Trustee on the Warrant Certificates) or be required
            to verify the same, but all such statements or recitals are and
            shall be deemed to be made by the Corporation;

      (b)   nothing herein contained shall impose any obligation on the Trustee
            to see to or to require evidence of the registration or filing (or
            renewal thereof) of this Indenture or any instrument ancillary or
            supplemental hereto;

      (c)   the Trustee shall not be bound to give notice to any person or
            persons of the execution hereof; and

      (d)   the Trustee shall not incur any liability or responsibility whatever
            or be in any way responsible for the consequence of any breach on
            the part of the Corporation of any of the covenants herein contained
            or of any acts of any directors, officers, employees, agents or
            servants of the Corporation.

9.08        REPLACEMENT OF TRUSTEE; SUCCESSOR BY MERGER

      (a)   The Trustee may resign its trust and be discharged from all further
            duties and liabilities hereunder, subject to this Section 9.08, by
            giving to the Corporation not less than 90 days' prior notice in
            writing or such shorter prior notice as the Corporation may accept
            as sufficient. The Warrantholders by extraordinary resolution shall
<PAGE>
                                   - 35 -

            have power at any time to remove the existing Trustee and to appoint
            a new trustee. In the event of the Trustee resigning or being
            removed as aforesaid or being dissolved, becoming bankrupt, going
            into liquidation or otherwise becoming incapable of acting
            hereunder, the Corporation shall forthwith appoint a new trustee
            unless a new trustee has already been appointed by the
            Warrantholders; failing such appointment by the Corporation, the
            retiring Trustee or any Warrantholder may apply to a justice of the
            Supreme Court of the Province of British Columbia, on such notice as
            such justice may direct, for the appointment of a new trustee; but
            any new trustee so appointed by the Corporation or by the Court
            shall be subject to removal as aforesaid by the Warrantholders. Any
            new trustee appointed under any provision of this Section 9.08 shall
            be a corporation authorized to carry on the business of a trust
            company in the Province of British Columbia and, if required by the
            Applicable Legislation for any other provinces, in such other
            provinces. On any such appointment the new trustee shall be vested
            with the same powers, rights, duties and responsibilities as if it
            had been originally named herein as Trustee hereunder.

      (b)   Upon the appointment of a successor trustee, the Corporation shall
            promptly notify the Warrantholders thereof in the manner provided
            for in Article X hereof.

      (c)   Any corporation into or with which the Trustee may be merged or
            consolidated or amalgamated, or any corporation resulting
            therefrom to which the Trustee shall be a party, or any
            corporation succeeding to the trust business of the Trustee shall
            be the successor to the Trustee hereunder without any further act
            on its part or any of the parties hereto, provided that such
            corporation would be eligible for appointment as a successor
            trustee under subsection 9.08(a).

      (d)   Any Warrant Certificates countersigned but not delivered by a
            predecessor trustee may be countersigned by the successor trustee in
            the name of the predecessor or successor trustee.

9.09        CONFLICT OF INTEREST

      (a)   The Trustee represents to the Corporation that at the time of
            execution and delivery hereof no material conflict of interest
            exists between its role as a trustee hereunder and its role in any
            other capacity and agrees that in the event of a material conflict
            of interest arising hereafter it will, within 90 days after
            ascertaining
<PAGE>
                                   - 36 -

            that it has such material conflict of interest, either eliminate the
            same or assign its trust hereunder to a successor trustee approved
            by the Corporation and meeting the requirements set forth in
            subsection 9.08(a). Notwithstanding the foregoing provisions of this
            subsection 9.09(a), if any such material conflict of interest exists
            or hereafter shall exist, the validity and enforceability of this
            Indenture and the Warrant Certificates shall not be affected in any
            manner whatsoever by reason thereof.

      (b)   Subject to subsection 9.09(a), the Trustee, in its personal or any
            other capacity, may buy, lend upon and deal in securities of the
            Corporation and generally may contract and enter into financial
            transactions with the Corporation or any subsidiary of the
            Corporation without being liable to account for any profit made
            thereby.

9.10        ACCEPTANCE OF TRUST

            The Trustee hereby accepts the trusts in this Indenture declared and
provided for and agrees to perform the same upon the terms and conditions herein
set forth.

9.11        TRUSTEE NOT TO BE APPOINTED RECEIVER

            The Trustee and any person related to the Trustee shall not be
appointed a receiver, a receiver and manager or liquidator of all or any part of
the assets or undertaking of the Corporation.

9.12        INDEMNIFICATION

            Without limiting any protection or indemnity of the Trustee under
any other provision hereof, or otherwise at law, the Corporation hereby agrees
to indemnify and hold harmless the Trustee from and against any and all
liabilities, losses, damages, penalties, claims, actions, suits, costs, expenses
and disbursements, including reasonable legal or advisor fees and disbursements,
of whatever kind and nature which may at any time be imposed on, incurred by or
asserted against the Trustee in connection with the performance of its duties
and obligations hereunder, other than such liabilities, losses, damages,
penalties, claims, actions, suits, costs, expenses and disbursements arising by
reason of the negligence or fraud of the Trustee. This provision shall survive
the resignation or removal of the Trustee, or the termination of the Indenture.
The Trustee shall not be under any obligation to prosecute or to defend any
action or suit in respect of the relationship which, in the opinion of its
counsel, may involve it in expense or liability, unless the Company shall, so
often as required, furnish the Trustee with satisfactory indemnity and funding
against such expense or liability.

      (c)   If, by reason of a strike, lockout or other work stoppage, actual or
            threatened, involving postal employees, any notice to be given to

            unlikely to reach its destination, such notice shall be valid and

            or if delivered to the address for such Warrantholders contained

represented thereby for all purposes, and the Corporation and the Trustee shall
not be affected by any notice or knowledge to the contrary except where the
Corporation or the Trustee is required to take notice by statute or by order of
a court of competent jurisdiction. A Warrantholder shall be entitled to the
rights evidenced by such Warrant Certificate free from all equities or rights of
set-off or counterclaim between the Corporation and the original or any
intermediate holder thereof and all persons may act accordingly and the receipt
of any such Warrantholder for the Common Shares which may be acquired pursuant
thereto shall be a good discharge to the Corporation and the Trustee for the
same and neither the Corporation nor the Trustee shall be bound to inquire into
the title of any such holder except where the Corporation or the

These Class B Warrants shall be deemed to be so surrendered only upon personal

In the event of any alteration of the Common Shares, including any subdivision,
consolidation or reclassification, and in the event of any form of
reorganization of the Corporation, including any amalgamation, merger or
arrangement, an adjustment shall be made to the terms of the Class B Warrants
such that the holders thereof, upon exercise of any Class B Warrants following
the completion of any of the above noted events, will be entitled to receive the
same number and kind of securities that they would have been entitled to receive
had they exercised their Class B Warrants immediately prior to such event.

The registered holder of this Class B Warrant Certificate may at any time prior
to the Expiry Date of the Class B Warrants, upon surrender hereof to the Trustee
at its principal office in the City of Vancouver, British Columbia and payment
of the charges provided for in the Indenture, exchange this Class B Warrant
Certificate for other Class B Warrant Certificates evidencing Class B Warrants
entitling the holder to acquire in the aggregate the same number of Common
Shares as may be acquired under this Class B Warrant Certificate.

Corporation or entitle such holder to any right or interest in respect thereof
except as herein and in the Indenture expressly provided.

The Indenture contains provisions making binding upon all holders of Class B
Warrant Certificates outstanding thereunder resolutions passed at meetings of
such holders held in accordance with such provisions and instruments in writing
signed by the holders of Class B Warrants entitled to acquire a specified
majority of the Common Shares which may be acquired pursuant to all then

Commercial Field. For the purpose of this clause, the value of each barrel of
Petroleum produced in said field during a calendar month will be the average
price by barrel that THE ASSOCIATE receives of the sales of its participation in
the Petroleum produced in the Contracted Area during the same month. When THE
ASSOCIATE has reimbursed the percentage established in this clause, all the
drilled wells, the installations and all kinds of assets acquired by THE
ASSOCIATE for the exploitation of the field and paid as indicated in this
clause, will become property of the Joint Account free of charge, previous
acceptance of ECOPETROL of participating in the development of such field.

            14.2.1 For the purpose of this clause, field hydrocarbons
accumulation that is found stored within an area accepted as commercial included
the zone of five reservation (5) kilometers wide surrounding it, as referred to
in Clause 8 (subparagraph 8.1) of this contract.

            14.2.2 Should several Commercial Fields be discovered under this
Contract, the production distribution percentage of the field having the
greatest total accumulated production shall apply to the distribution of the
production from all Commercial Fields in the Contracted Area.

            14.2.3 Should a field produce crude oil and gas, in order to apply
the above distribution table, the total accumulated production to be taken into
account shall be that of the main hydrocarbon in keeping with the authorization
granted by the Ministry of Mines and Energy for exploitation of said field. In
order to determine the total accumulated production, the measure for the
equivalent gas is the amount of 7,000 standard cubic feet of gas per barrel of
oil.

            14.3 In addition to the jointly owned tanks and other facilities
each Party shall have the right to build its own production facilities in the
Contracted Area for its own and exclusive use in compliance with legal
regulations. The transport and delivery of each Party's Oil to the pipeline and
to other storage facilities not jointly owned, shall be the sole responsibility
and risk of the receiving Party.

sell it or dispose of it separately, at its own expense, as provided for in
Clause 14 (subparagraph 14.3).

            14.6 If some of the Parties, by any reason, can not separately have
or withdraw from the tanks from the Joint Account all or part of the Petroleum
that corresponds to it according to this contract, the following procedure is
applied:

            14.6.1 If ECOPETROL is the Party that is unable to withdraw in whole
or in part its quota of Oil (in other words, share plus royalty) pursuant to
Clause 12 (subparagraph 12.3), the Operator may continue producing the field and
delivering to THE ASSOCIATE, in addition to the portion representing THE
ASSOCIATE'S quota in the operation on the basis of one hundred percent (100%) of
the MER, all such Oil as THE ASSOCIATE chooses and is able to withdraw up to the
limit of one hundred percent (100%) of the MER, crediting ECOPETROL for
subsequent delivery, the volume of Oil ECOPETROL was entitled to withdraw but
failed to do so. But with respect to volume of Petroleum not withdrawn that
corresponds in the month by royalties to ECOPETROL, THE ASSOCIATE at the request
of ECOPETROL, will pay in dollars of the United States of America, the
difference between the quantity of Petroleum withdrawn and the quantity of
Petroleum that corresponds on account of the royalty referred to in the Clause
13 (subparagraphs 13.1 and 13.2), it being understood that any Oil withdrawal
made by ECOPETROL shall be applied in the first place to royalty payment in
kind, and subsequently, any additional Oil withdrawals shall be applied to
ECOPETROL'S share under Clause 14 (subparagraph 14.2)

            14.6.2 In case that THE ASSOCIATE will be the Party that can not
withdraw, in all or in part, its portion assigned under the Clause 12
(subparagraph 12.3), the Operator will deliver to ECOPETROL, based on one
hundred percent (100%) of the MER, not only the participation and the quota that
corresponds, but also the Petroleum that ECOPETROL is in capacity from
withdrawing until a limit from one hundred percent (100%) of the MER,
accrediting with THE ASSOCIATE subsequent delivery, the part that corresponds
and that may not have been able to withdraw.

            14.7 When both Parties are in of receiving the Oil allocated under
Clause 12 (subparagraph 12.3), the Operator shall deliver to the Party which had
been previously unable to receive its production quota, upon such Party's
request, in addition to its share in the operation, a minimum of ten percent
(10%) per month of the production corresponding to the other Party every month
and, by mutual agreement, up to one hundred (100%) of the non-received share, up
to the time when the total amounts credited to the Party that had been unable to
receive its Oil are canceled out.

            14.8 Without prejudice of the legal dispositions that regulate the
matter, each Party will have freedom, in any moment, of selling or exporting its
quota of obtained Petroleum, according to this contract, or having same in any
shape.

of commercial production from the field, will submit a project on the use of
natural gas for the benefit of the Joint Account. The Executive Committee shall
approve the project and decide on the schedule therefor. If the Operator fails
either to present any project within the two (2) years or to execute the
approved project within the time limits stipulated by the Executive Committee,
ECOPETROL may take free-of-charge all available gas from the exploitation
reservoirs except that required for the efficient exploitation of the field.

CLAUSE 16 - UNITIZATION

            Whenever an economically exploitable reservoir extends continuously
to a structure located in the Contracted Area and to another adjoining area or

operation of such well until when the net value of the production, after
deducting the production costs, or recollections, storage, transport and other
similar costs as well as sales, be equal to two hundred percent (200%) of the
drilling and completion cost of said well, that from now on for intents and
purposes of the present contract shall be the property of the Joint Account. For
purposes of this clause, the value of each barrel of Petroleum produced in said
well, during a calendar month, before deducting the previously mentioned costs,

plug a well that is not in commercial production or a dry well that may have
been drilled by the Joint Account, and if these operations have not been
included in a schedule approved by the Executive Committee, such Party will give
announcement to the other Part of its intention to workover, drill deeper or
plug such 

                                      23
<PAGE>
well. Should there be no equipment at the location the procedure set forth in
Clause 21 (subparagraphs 21.1 and 21.2) shall be applicable. If in the location
of the well is found the adequate equipment to effect the proposed operations,
the Party that receives the notice of the operation. If no response is received

CHAPTER V - JOINT ACCOUNT

CLAUSE 22 - MANAGEMENT

            22.1 Without prejudice to other provisions contained herein,
expenses covering Exploration Operations shall be for THE ASSOCIATE'S account
and risk.

            22.2 As from the time the Parties accept the existence of a
Commercial Field, and subject to the provisions of Clause 5 (subparagraph 5.2)
and Clause 13 (subparagraph 13.1 and 13.2), 

                                      24
<PAGE>
the ownership of the rights or Interest in the Operation of the Contracted Area
shall be divided as follows: ECOPETROL fifty percent (50%) and THE ASSOCIATE
fifty percent (50%). From then on, all expenses, payments, investments, costs
and obligations carried out and contracted for the performance of the operations
thereunder, as well as the investments made by THE ASSOCIATE before and after a
Commercial Field is accepted, in drilling and completing wells, which result in
production within the field, shall be charged to the Joint Account. Except as
provided in Clauses 14 (subparagraph 14.3) and 21, all property acquired or used
thereafter for the performance of activities of the Commercial Field operation
shall be paid and owned by the Parties in the proportions set forth in this
Clause.

            22.3 The first five (5) days of each month the Parties will, in the
bank designated by Operator, pay the Operator their share of Budget according to
the needs and in the currency in which the expenses should be made, that is to
say, in Colombian pesos or in dollars of the United States of America, according
to the Operator according to the schedules and cost estimates approved by the
Executive Committee. When THE ASSOCIATE does not have the necessary Colombian
pesos to cover the quota that it corresponds, to exchange in this currency,
ECOPETROL will have the right to supply such pesos and to receive the credit to
its dollar obligations, using the official rate for purchase of exchange
certificates of the Central Bank on the day ECOPETROL is to make such
contribution, provided such transaction is legally acceptable.

            22.4 The Operator shall present monthly to the Parties, and within
the thirty (30) days following calendar to the completion of each month, a
monthly statement in the one which shows the total anticipated, the effected
expenses, the pending obligations and a report of all the charges and credits
made to the Joint Account, report that is elaborated according to Annex "B". If
the payments as set forth in Clause 22 (subparagraph 22.3) are not made within
the anticipated term and the Operator elects to cover them, the slow paying
Party shall pay the Commercial Interest in the same currency in which may have
been caused the payment, during the term of delinquency.

            22.5 If either Party should fail to timely supply the Joint Account
the total that correspond, as of that such date, the Party shall be considered
"slow-pay" Party and, the other Party the "prompt" Party. If the prompt Party
has paid the delinquent Party's share, in addition to its own, the former shall
have the right, after a sixty (60) days delay, to have the Operator deliver to
the Delinquent Party's total participation in the Contracted Area, (excluding
the royalty percentage), up to such amount of production as shall give the
prompt Party a net income from sales equal to the sum not paid by the Delinquent
Party plus an annual interest equal to the Commercial Interest rate, 

                                      25
<PAGE>
beginning sixty (60) days after the date of commencement of delinquency. "Net
Income" is understood to mean the difference between the sales price of the
crude taken by the prompt Party, less cost of transportation, storage, loading
and other reasonable expenses incurred by the prompt Party in the sale of the
products taken. The prompt Party shall have thirty (30) days from having advised
the Delinquent Party in writing of its intention to take all or a part of the
Delinquent Party's share of the production.

            22.6.1 Without consideration to the percentages of production that
each one of the

Parties receives in the development of the contract, all the Direct Expenses of
the Joint Operation are charged to the Parties in the following proportion:

            The expense or appropriation Budget consists of the operating
expenses Budget and the investment Budget. Each such Budget is prepared
according to the monetary origin of its disbursement in pesos and dollars, and
is presented classified by programs and projects. The programs, in numerical
order within each Budget, represents the different 

                                      13

costs required by the facilities directly serving the Joint Operation and which
must therefore be assumed one hundred percent (100%) by the Joint Account and
charged to the Parties pursuant to Clause 22 (subparagraph 22.6.1 of the
Contract). Indirect costs to be paid from the Joint Account will be calculated
and charged to The Parties, determined as set forth on Clause 22 (subparagraph

                                      16
<PAGE>
            General Expenses shall be calculated by taking into account the
specific needs of the Joint Operation in the normal course of its activity.
Community Assistance will be budgeted on both the requests made by interested
parties and the Executive Committee policies on such matters. In special
duly-justified circumstances, the Operator may deal with requests in its
customary manner, after first advising each of the Parties.

            14.1.4 Budget Execution: The operating Expense Budget shall be
performed as follows:

            14.1.4.1 All services, purchases or contracts charged to the Joint

            14.1.2 When the cost of the service or activity to be contracted is
within the limits established for the Association, the Operator shall have full
autonomy to sign contracts pursuant to its own internal authority and
responsibility.

            14.1.4.3 Purchases, contracts or any other action whose costs exceed
established limits either partially or totally must be submitted to the
Association's Technical Sub-Committee for study and recommendation.

            14.1.5 Budget Execution Control: The Operator is responsible for

14.1.5.4 Justification of possible budget additions, adjustments or transfers
proposed by one of the Parties or which the Operator considers suitable.

            14.2 Investment Budget: This constitutes the basic tool for the
planning, execution and control of each investment project and program planned
by the Joint Operation, and serves as a means of estimating funds required for
the execution of the various programs approved by the Executive Committee.

            First, the Executive Committee, through the respective
Sub-Committees, will fix the general parameters and policies to be considered by
the investment plan.

            14.2.1 The investment Budget is composed of items allotted for the
following:

            14.2.1.1 Acquisition of durable goods, materials and services
required for the different Association projects.

            14.2.1.2 Acquisition of equipment and major maintenance tools for
the Association's workshops in order to guarantee normal operation's
development.

            14.2.1.3 Provision of social amenities and other constructions
and/or building extensions required by the operation, including facilities for
the Joint Account workers.

            14.2.2 Classification of the Investment Budget: For all presentation
purposes, the investment Budget shall be grouped into programs and projects as
follows: Development wells, production facilities, civil works, other assets,
special studies warehouse and other projects. These in turn will be broken down
into the following projects:

                                      18
<PAGE>
            14.2.2.1 Development Wells: Surface or Pumping Equipment and
Workover; Producing Wells; Locations.

            14.2.2.2 Production facilities: System of crudes collection; Storage
system; System of crude treatment; Improved recovery system; Pumping stations;
Transfer lines; Other.

            14.2.2.3 Civil works: Highways; Bridges; Constructions (camps,
workshops, warehouses and offices).

            14.2.2.4 Other Assets: Vehicle Fleet; Fire-fighting equipment;
Communications equipment; Electromechanical Maintenance Equipment; Major tools;
Cleaning or Workover Equipment.

            14.2.2.5 Special Studies: Environmental impact; Reservoir studies,
Simulation studies; Interference tests.

            14.2.2.6 Warehouses: Fluctuation of material stock.

            14.2.2.7 Each one of these projects can be broken down into sub-
projects as needed, maintaining a uniform identification. Final presentation
shall be made on a project-by-project basis, according to the classification
given above and using Forms two (2) and four (4). These forms may be modified by
agreement between the Parties at the Financial Sub-Committee. For greater
clarity in preparation of the investment Budget, the following considerations
should be taken into account.

            14.2.2.7.1 Maintenance Projects: All investments made in equipment,
materials, and construction for the purpose of keeping facilities in good
operating condition as per their original capacity and performance limits.

                                      19
<PAGE>
            14.2.2.7.2 Enlargement Projects: These are investments designed to
increase facilities capacity, the authorized size of the vehicle fleet, office
equipment, etc.

            14.2.2.7.3 Special Projects: All those projects which deserve being
classified as special due to their size, industrial importance, or social or
ecological impact.

            14.2.3 Budget Preparation and Presentation: Each project in the
investment Budget must be fully justified and analyzed before being included in
the general Budget. To this end, the Operator must therefore draw up a
preliminary investment report containing the following general information:
Analysis of requirement/needs; Justification of the project; General project
description; Estimated amount of investment; Time required for execution;
Economic appraisal. The report showing the aforementioned data, as well as
anything else deemed necessary for appraisal purposes, shall be studied jointly
by the SubCommittees, Association's Sub-Committees, who will either recommend or
object to the viability of the project in keeping with the policies established
by the Executive Committee.

            Once such Sub-Committee recommends the execution of a specific
project, it will be included in the General Budget to be approved by the
Association's Executive Committee.

            All the general information used to justify each project will be
compiled in a Technical-Financial Annex which will serve as a support when
presenting the Budget for the approval of the Executive Committee.

            14.2.4 Consolidation of the investments budget: Once the Joint
Operator's requirements have been defined, the Operator will consolidate the
investment Budget according to the classification in Clause 14 (subparagraph
14.2.2) of this Annex and 

                                      20
<PAGE>
shall present it to the Association's Executive Committee for final approval.
The expense Budget, as well as the program investment Budget, will be submitted
in three columns: Dollar-origin disbursements, pesos-origin disbursements, and
consolidated total in dollars.

            For information purposes, the Operator will also prepare a
disbursement schedule, specifying quarterly cash requirements, currency thereof,
the program when it is a case of investments, and total expenses when it is for
operating expenses.

            14.2.5 Budget Performance: The Operator, through its various
facilities, will execute the investment Budget according to previously
established schedules.

            A pre-defined code will be used to identify the appropriations
assigned to each project and will be used in all documents derived from Budget
Performance.

            14.2.6 Budget Control: The Operator shall be responsible for the
performance of each investment program and project and will be responsible for
their execution under the conditions approved therefor.

            Likewise, the Operator shall make sure that procedures needed to
effect the projects are taken in due time and in the proper way. Should the
Operator encounter any difficulty impeding the normal progress of such projects,
it shall immediately advise each Party in writing in order to seek a solution.

            The Operator, as the Party in charge of the projects, shall prepare
quarterly technical and Budget progress reports, submitting them to each Party
sufficiently in advance of the next ordinary meeting of the Executive Committee.

            The quarterly report that should be made by the Operator through his
own facilities should include the following information:

                                      21
<PAGE>
            o  Period covered by the report

            o  Code and description of the project

            o  Total Budget of the project

            o  Financial advances from its start up to cut off date

            o  Investments per current year project, accumulated to date

            o  Technical progress of work

            o  Quarterly projection of work to be executed up to year-end for
               information purposes

CLAUSE 15 - OTHER PROVISIONS

            15.1 Budget Additions: In all cases, the Operator has authority to
incur in all operating expenses and make all investments as may be required by
the Joint Operation within the approved Budget, without exceeding ten percent
(10%) of the appropriates made for each project for the respective term (Clause
11, subparagraph 11.5 of The Contract). However, if during Budget performance,
additions to the value of the appropriations approved by the Executive
Committee, need to be made the applicable changes can be requested.

            From time to time, requests for additions to or carry-overs in
expense or investments budgets can be submitted, analyzed and approved at each
ordinary meeting of the Executive Committee. However, the Executive Committee
can also hold special meetings to discuss budgetary matters whenever a special
situation so requires.

                                      22
<PAGE>
            In consequence, each time a Budget revision is requested, the
Operator must initiate the corresponding proceedings in due time by submitting
applications to the respective Subcommittee for study and subsequent
recommendation to the Executive Committee.

            In any case, applications for additional funds must be fully
justified by explaining the reasons that cause such variation of the sums
allocated, with the respective technical and financial annexes as contemplated
in Clause 14 (subparagraph 14.2.3) of this Agreement.

            15.2 Carry-Overs: Budgetary carry-overs shall be those movements
made from one year to the next for such projects that could not be finished in
the year for which they had been budgeted (due to unavailability of equipment,
importation procedures, bad weather, etc.)

            The value of a project which has not been totally performed will be
carried over to the next year's Budget and submitted to the Executive Committee
for ratification purposes. Each sub project shall be expressly identified in the
Budget and shall be taken into account at the time of preparing the disbursement
schedule mentioned in Clause 15 (subparagraph 15.4) of this Agreement.
Furthermore, carry-overs shall give rise to an attachment explaining the reasons
therefor and how they will be performed in the next period.

            If a project was left more than eighty percent (80%), such must be
included again into the Budget as a new project. Therefore, it must be
accompanied by the information contemplated in Clause 14 (subparagraph 14.2.3)
of this ANNEX.

Utica in the Cundinamarca Department.

The description of this area follows here and also appears on the map which is a
next here as Annex "A", which forms part of this Contract, as does the chart of
corresponding calculation: it has been taken as a reference point the Geodesic
Vertex "CINTA-24" of the Geographical Institute of Agustin Codazzi whose Gauss
plane coordinates with origin Santa Fe of Bogota are: N-1,063,470.38 meters,
E-951,466.09 meters which correspond to the geographic coordinates Latitude
05(degree) 10'22".276 to the north of the equator, Longitude
74(degree)31'07".154 to the west of Greenwich. From this vertex, you continue on
a northern direction to north N 57(degree) 45'09".072 West for a distance of
4,553.45 meters until you reach point "A" which this point's coordinates are:
N-1,065,900.0 meters, E-947,15.00 meters. From this point "A" continue in a
northern direction for a distance of 4,100.00 meters until you reach point "B"
whose coordinates are: N-1,070,000.00 meters, E-

                                       -3-
<PAGE>
947,615.00 meters. From this point "B" continue in an eastern direction for a
distance of 4,385.00 meters until you reach point "C" whose coordinates are:
N-1,070,000.00 meters, E-952,000.00 meters. From this point "C" continue the
direction S 7(degree) 7'30".059 E for a distance of 16,124.51 meters until
reaching point "D" whose coordinates are: N-1,054,000.00 meters, E-954,000.00
meters. From this point "D" continue with a direction S 15(degree) 42'31".096 W
for a distance of 16,620.77 meters until reaching point "E" whose coordinates
are: N-1,038,000.00, E-949,500.00 meters. From this point "E", continue with a
western direction for a distance of 5,800.00 meters until reaching point "F"
whose coordinates are: N-1,038,000.00 meters, E-943,700.00 meters. From this
point "F", continue with a northern direction for a distance of 27,900.00 meters
until reaching point "G" whose coordinates are: N-1,065,900.00 meters,
E-943,700.00 meters. From this point "G" continue in an eastern direction for a
distance of 3,915.00 meters until reaching point "A" which was the departure
point and the closing of the delimitation of the boundaries.

SECOND: Modify Clause 5, points 5.1.1., 5.1.2., and 5.1.3., which will now read
in this fashion:

advises THE ASSOCIATE that it does not acknowledge commercial development. For
purposes of settlement, the dollar equivalent of the disbursements made in pesos
shall be calculated utilizing the exchange rate on the date THE ASSOCIATE made
said disbursements. For the purpose of this clause, the value of each barrel of
Oil produced in said field during a calendar month shall be the average price
per barrel that THE ASSOCIATE receives from the sales of its share in the Oil
produced in the Contracted Area during said month. When THE ASSOCIATE has been
reimbursed for the percentage established in this clause, all the drilled wells,
the installations and all assets acquired by THE ASSOCIATE for the exploitation
of the field and paid as indicated in this clause, shall become property of the
Joint Account free of charge, after agreement by ECOPETROL to participate in the
development of said field.

9.6 ECOPETROL may at any time decide to participate in the operations at the
field discovered and developed by THE ASSOCIATE, without prejudicing THE
ASSOCIATE'S right to reimburse itself for the investments made on its own, in
the manner and percentage stated in Clause 9 (numeral 9.5). Once THE ASSOCIATE
has been reimbursed, ECOPETROL shall start to participate in the financial
results of the developed wells entirely at expense of THE ASSOCIATE.

9.7 To define the limits of a Commercial Field all the geological and
geophysical information shall be considered as well as that pertaining to the
drilled wells within said field or those related to said field.

9.8 If upon expiration of the six (6) year Exploration Period referred to in

                                      -11-
<PAGE>
Where:

IA (THE ASSOCIATE'S ACCUMULATED INCOME): Is the actual value of THE ASSOCIATE'S
accumulated income derived from the total production of hydrocarbons at the
reference price agreed to by the Parties, excluding hydrocarbons re-injected
into the Fields of the Contracted Area, those consumed in the operation and
burnt gas.

The average reference price for hydrocarbons shall be determined pursuant to
mutual agreement between the Parties.

In order to determine Accumulated Income, one should take as base the Monthly
Income, which in turn shall be determined by multiplying the average reference
monthly price by the monthly production, in accordance with MME's Form 9.

ID (ACCUMULATED DEVELOPMENT INVESTMENTS): Consist of fifty percent (50%) of the
accumulated development investment approved by the Association's Executive
Committee. 

A: Consists of the Direct Exploration Costs THE ASSOCIATE has incurred, in
accordance with Clause 9 (numerals 9.2.2, 9.2.3 and 9.2.4) of this Contract.

B: Is the accumulated reimbursement of the previously indicated Direct
Exploration Costs, in accordance with Clause 9 (numerals 9.2.2, 9.2.3 and 9.2.4)
of this Contract.

GO (ACCUMULATED OPERATIONAL COSTS): Consist of the accumulated operational
costs, as approved by the Association's Executive Committee, in the proportion
corresponding to THE ASSOCIATE, plus THE ASSOCIATES accumulated transportation
costs. Transportation costs are understood to be the investment and operational
costs incurred for the transportation of hydrocarbons produced in the commercial
fields located in the Contracted Area, from this Area to the exporting port of
the reference price at a certain site which the Parties have agreed to utilize
for purposes of calculating the IA income. Said transportation costs shall be
determined jointly by the Parties by mutual agreement once the exploitation
stage begins on those fields whose commercial feasibility has been acknowledged
by ECOPETROL.

Operational Costs shall include Special Contributions or similar contributions
having direct application on hydrocarbon exploitation in the Contracted Area.

All values included in the determination of the R Factor shall be given in
current dollars. For this purpose expenses given in pesos shall be converted
into dollars at the Prevailing Exchange Rate as certified by the Bank of the
Republic effective on the date said disbursements took place.

14.2.4 Factor R Calculations: The distribution of production based upon Factor R
shall commence on the first day of the third calendar month following the month
in which the accumulated production in the Contracted Area reaches 60 million
barrels of Oil.
Factor R shall be calculated based upon the closing of the accounting books for
the calendar month in which accumulated production reached 60 million barrels of
Oil. The resulting production distribution shall be applicable until the 30th
day of June of the following year. From that moment, the Factor R distribution
of production shall be carried out annually (from July 1st to June 30th),
settlement being based upon the accumulated value from December 31st of the
previous year in accordance with the corresponding closing of the accounting
books.

14.2.5 Should a field produce crude oil and gas at the same time, in
order to apply the above distribution table, the total accumulated production to
be taken into account shall be that of the principal hydrocarbon, in keeping
with the authorization granted by the Ministry of Mines and Energy

                                      -12-

performance of the operations, in accordance with this contract, as well as the
investments made by THE ASSOCIATE before and after a Commercial Field is
Acknowledged, in drilling and completing wells, which result in production

(30) calendar days following the end of the month, a monthly statement showing

former shall have the right, after a sixty (60) days waiting period, to have the
Operator deliver the Delinquent Party's total participation in the Contracted
Area, (excluding the royalty percentage), up to the amount of production which
permits the prompt Party realize a net income from sales equal to the

Commercial Interest rate, beginning sixty (60) days after the date of
commencement of delinquency. "Net Income" is understood to mean the difference
between the sales price of the crude taken by the prompt Party, less cost of
transportation, storage, loading and other reasonable expenditures incurred by
the prompt Party in the sale of the products taken. The prompt Party shall have
thirty (30) days from the date of written notice to the Delinquent Party of its
intention to take all or a part of the Delinquent Party's share of production.

technical support) and applying the equation a+m (X-b); where X = total annual
investments and expenditures, and "a", "m" and "b", are constants whose value is

              that would be covered by the insurance procured under Article 4.7
              (B), and which the Operating Committee may determine to be
              acceptable. No such determination of acceptability shall in any
              way absolve a non-participating Party from its obligation to meet
              each cash call including any cash call in respect of damages and
              losses and/or the costs of remedying the same in accordance with
              the terms of this Agreement. If such Party obtains other
              insurance, such insurance shall contain a waiver of subrogation in
              favor of all the other Parties and the Operator, but only in
              respect of their interests under this Agreement.

       (D) The cost of insurance in which all the Parties are participating
       shall be for the Joint Account and the cost of insurance in which less
       than all the Parties are participating shall be charged to the Parties
       participating in proportion to their respective Participating Interests.

       (E) Operator shall, in respect of all insurance obtained pursuant to this
       Article:

              (1) promptly inform the participating Parties when such insurance
              is obtained and supply them with copies of the relevant policies
              when the same are issued;

                                       24
<PAGE>
              (2) arrange for the participating Parties, according to their
              respective Participating Interests, to be named as co-insureds on
              the relevant policies with waivers of subrogation in favor of all
              the Parties; and

              (3) duly file all claims and take all necessary and proper steps
              to collect any proceeds and credit any proceeds to the
              participating Parties in proportion to their respective
              Participating Interests.

       (F) Operator shall use its reasonable efforts to require all contractors
       performing work in respect of Joint Operations to obtain and maintain any
       and all insurance in the types and amounts required by any applicable
       laws, rules and regulations or any decision of the Operating Committee
       and shall use its reasonable efforts to require all such contractors to
       name the Parties as additional insureds on contractor's insurance
       policies or to obtain from their insurers waivers of all rights or
       recourse against Operator and Non-Operators.

4.10   REMOVAL OF OPERATOR

       (A) Subject to Article 4.11, Operator shall be removed upon receipt of

       breach. Any decision of Non-Operators to give notice of breach to
       Operator or to remove Operator under this Article 4.10(B) shall be made
       by an affirmative vote of two or more non-

                                       26

       shall vote within thirty (30) Days of such notification on whether or not
       a successor Operator should be named pursuant to Article 4.11. For

        Operator against its will. 

       (B) If the Operator disputes commission of or failure to rectify a
       material breach alleged pursuant to Article 4.10(B) and proceedings are
       initiated pursuant to Article XVIII, no successor Operator may be

       (C) If an Operator is removed, other than in the case of Article 4.10(C)
       or Article 4.10(D), neither Operator nor any Affiliate of Operator shall
       have the right to vote for itself on the appointment of a successor
       Operator, nor be considered as a candidate for the successor Operator.

       (D) A resigning or removed Operator shall be compensated out of the Joint

       or removal, except in the case of Article 4.10(B).

       (E) The Operating Committee shall arrange for the taking of an
       independent inventory of all Joint Property and Hydrocarbons, and an
       audit of the books and records of the removed Operator. Such inventory
       and audit shall be completed, if possible, no later than the effective
       date of the change of Operator. The liabilities and expenses of such
       inventory and audit shall be charged to the Joint Account.

       Operator shall succeed to all duties, rights and authority prescribed for
       Operator. The former Operator shall transfer to the successor Operator
       custody of all Joint Property, books of account, records and other
       documents maintained by Operator pertaining to the Contract Area and to
       Joint Operations. Upon delivery of the above-described property and data,

5.13   EFFECT OF VOTE

       All decisions taken by the Operating Committee pursuant to this Article,
       shall be conclusive and binding on all the Parties, except that: (A) If
       pursuant to this Article, a Joint Operation, other than an operation to
       fulfill the Minimum Work Obligations,

                                       35
<PAGE>
       has been properly proposed to the Operating Committee and the Operating
       Committee has not approved such proposal in a timely manner, then any
       Party shall have the right for the appropriate period specified below to
       propose in accordance with Article VII, an Exclusive Operation involving
       operations essentially the same as those proposed for such Joint
       Operation.

              (1) For proposals involving the use of a drilling rig that is
              standing by in the Contract Area, such right shall be exercisable
              for twenty-four (24) hours after the time specified in Article
              5.12(A)(1) has expired.

              (2) For proposals to develop a Discovery, such right shall be
              exercisable for ten (10) Days after the date the Operating
              Committee was required to consider such proposal pursuant to
              Article 5.6 or Article 5.12;

              (3) For all other proposals, such right shall be exercisable for
              five (5) Days after the date the Operating Committee was required
              to consider such proposal pursuant to Article 5.6 or Article 5.12.

       (B) If a Party voted against any proposal which was approved by the
       Operating Committee and which could be conducted as an Exclusive
       Operation pursuant to Article VII other than any proposal relating to
       Minimum Work Obligations, then such Party shall have the right not to

                                       36
<PAGE>
       participate in the operation contemplated by such approval. Any such
       Party wishing to exercise its right of non-consent must give notice of
       non-consent to all other Parties within five (5) Days (or within
       twenty-four (24) hours if the drilling rig to be used in such operation
       is standing by in the Contract Area) following Operating Committee
       approval of such proposal. The Parties that were not entitled to give or
       did not give notice of non-consent shall be Consenting Parties as to the
       operation contemplated by the Operating Committee approval, and shall
       conduct such operation as an Exclusive Operation under Article VII. Any
       Party that gave notice of non-consent shall be a Non-Consenting Party as
       to such Exclusive Operation. 

       (C) If the Consenting Parties to an Exclusive Operation under Article
       5.13(A) or Article 5.13(B) concur, then the Operating Committee may, at
       any time, pursuant to this Article, reconsider and approve, decide or
       take action on any proposal that the Operating Committee declined to
       approve earlier, or modify or revoke an earlier approval, decision or
       action.

       (D) Once a Joint Operation for the drilling, Deepening, Testing,
       Sidetracking, Plugging Back, Completing, Recompleting, Reworking or
       plugging of a well, has been approved and commenced, such operation shall
       not be

                                       37
<PAGE>
       discontinued without the consent of the Operating Committee; provided,
       however, that such operation may be discontinued, if:

              (1) an impenetrable substance or other condition in the hole is
              encountered which in the reasonable judgment of Operator causes
              the continuation of such operation to be impractical; or

              (2) other circumstances occur which in the reasonable judgment of
              Operator causes the continuation of such operation to be
              unwarranted and after notice the Operating Committee within the
              period required under Article 5.12(A)(1) approves discontinuing
              such operation.

       On the occurrence of either of the above, Operator shall promptly notify
       the Parties that such operation is being discontinued pursuant to the
       foregoing, and any Party shall have the right to propose in accordance
       with Article VII an Exclusive Operation to continue such operation.

                     ARTICLE VI - WORK PROGRAMS AND BUDGETS

6.1    EXPLORATION AND APPRAISAL

                                       38
<PAGE>
       (A) The Parties recognize that they have previously approved the Work
       Program and Budget for the initial Contract Year, which includes the
       first two wells under the Contract as the Minimum Work Obligations for
       such Year. Each Party agrees to pay its share of such wells as set forth
       in Article 3.1(A). The provisions of Articles 6.1(B) shall govern Work
       Programs and Budgets for the second and subsequent Contract Years.

       (B) On or before the first day of the fourth month of each Contract Year,
       Operator shall deliver to the Parties a proposed Work Program and Budget
       detailing the Joint Operations to be performed in the Contract Area for
       the such Contract Year. Within forty-five (45) Days of such delivery, the
       Operating Committee shall meet to consider and to endeavor to agree on a
       Work Program and Budget.

       (C) If a Discovery is made, Operator shall deliver any notice of
       Discovery required under the Contract and shall as soon as possible
       submit to the Parties a report containing available details concerning
       the Discovery and Operator's recommendation as to whether the Discovery
       merits appraisal.

       If the Operating Committee determines that the Discovery merits
       appraisal, Operator within sixty (60) Days, shall deliver to the Parties
       a proposed Work Program and Budget for the appraisal of the Discovery.
       Within thirty (30) Days

                                       39
<PAGE>
       of such delivery, or earlier if necessary to meet any applicable deadline
       under the Contract, the Operating Committee shall meet to consider,
       modify and then either approve or reject the appraisal Work Program and
       Budget. If the appraisal Work Program and Budget is approved by the
       Operating Committee, Operator shall take such steps as may be required
       under the Contract to secure approval of the appraisal Work Program and
       Budget by the Government and Government Oil Company. In the event the
       Government or the Government Oil Company requires changes in the
       appraisal Work Program and Budget, the matter shall be resubmitted to the
       Operating Committee for further consideration.

       (D) Each Party hereby agrees to a Work Program and Budget to the extent
       that it includes the Minimum Work Obligations, required by the Contract
       to be carried out during the Contract Year in question. If within the
       time periods prescribed in this Article the Operating Committee is unable
       to agree on other items included in Work Program and Budget, Operator
       shall take such actions, but only such actions for the Joint Account as
       are necessary to maintain the Contract in full force and effect,
       including the commencement of a Work Program and Budget to fulfill the
       Minimum Work Obligations required for the given Contract Year.

                                       40
<PAGE>
       (E) Subject to Article 6.7, approval of any such Work Program and Budget,
       which includes:

              (1) an Exploration Well, whether by drilling, Deepening or
              Sidetracking, shall include approval for all expenditures
              necessary for drilling, Testing and Completing such Exploration
              Well.

              (2) an Appraisal Well, whether by drilling, Deepening or
              Sidetracking, shall include approval for all expenditures
              necessary for drilling, Testing and Completing such Appraisal
              Well.

       (D) Subject to this Article, any operation that may be proposed and
       conducted as a Joint Operation, other than operations pursuant to an

       Operation.

7.2    PROCEDURE TO PROPOSE EXCLUSIVE OPERATIONS 

       (A) Subject to Articles V and 7.1, if any Party proposes to conduct an
       Exclusive Operation, such Party shall give notice

                                       50

       operation. Such notice shall specify that such operation is proposed as
       an Exclusive Operation, the work to be performed, the location, the
       objectives, and estimated cost of such operation. 

       (B) Any Party entitled to receive such notice shall have the right to
       participate in the proposed operation.

              (1) For proposals to Deepen, Test, Complete, Sidetrack, Plug Back,
              Recomplete or Rework involving the use of a drilling rig that is
              standing by in the Contract Area, any such Party wishing to
              exercise such right must so notify Operator within forty-eight

              Exclusive Operation.

              (3) For all other proposals, any such Party wishing to exercise
              such right must so notify Operator within ten (10) Days after

       (C) Failure of a Party to whom a proposal notice is delivered to properly
       reply within the period specified

                                       51
<PAGE>
       above shall constitute an election by that Party not to participate in
       the proposed operation.

       (D) If all Parties properly exercise their rights to participate, then
       the proposed operation shall be conducted as a Joint Operation. The
       Operator shall commence such Joint Operation as promptly as practicable
       and conduct it with due diligence.

       (E) If less than all Parties entitled to receive such proposal notice
       properly exercise their rights to participate, then:

              (1) The Party proposing the Exclusive Operation, together with any
              other Consenting Parties, shall have the right exercisable for the
              applicable notice period set out in Article 7.2(B), to instruct
              Operator (subject to Article 7.9(G)) to conduct the Exclusive
              Operation.

              (2) If the Exclusive Operation is conducted, the Consenting
              Parties shall bear the sole liability and expense of such
              Exclusive Operation in a fraction, the numerator of which is such
              Consenting Party's Participating Interest as stated in Article 3.1
              and the denominator of which is the aggregate of the Participating
              Interests of the Consenting Parties as stated in Article 3.1, or
              in such other proportion totaling one hundred percent (100%) of
              such liability

                                       52
<PAGE>
              and expense as the Consenting Parties may agree; provided that,
              for operations during the Exploration Period for which Petrolinson
              is carried pursuant to Article 3.1(A), the interest of each Party
              other than Petrolinson shall be increased as provided in that
              Article.

              (3) If work in the field on such Exclusive Operation has not been
              commenced within ninety (90) Days (excluding any extension
              specifically agreed by all Parties or allowed by the force majeure
              provisions of Article XVI), the right to conduct such Exclusive
              Operation shall terminate. If any Party still desires to conduct
              such Exclusive Operation, written notice proposing such operation
              must be resubmitted to the Parties in accordance with Article V,
              as if no proposal to conduct an Exclusive Operation had been
              previously made.

7.3    RESPONSIBILITY FOR EXCLUSIVE OPERATIONS

       (A) The Consenting Parties shall bear in accordance with the
       Participating Interests agreed under Article 7.2(E) the entire cost and
       liability of conducting an Exclusive Operation and shall indemnify the
       Non-Consenting Parties from any and all costs and liabilities incurred
       incident to such Exclusive Operation (including but not limited to all

                                       53

       Participating Interest share of the cost and liability incident to the
       operations in which it participated, including but not limited to
       plugging and abandoning and restoring the surface location, but only to
       the extent those costs were not increased by the Exclusive Operation.

                                       57
<PAGE>
       (B) The In Kind Penalty shall be deemed fully satisfied when the proceeds
       (less taxes measured by production, royalties and other burdens on
       production) of the sale of Hydrocarbons received by the Consenting
       Parties as equals the sum of the In Kind Penalty calculated in U.S.
       dollars pursuant to Articles 7.5(A) and (C)). After such satisfaction the
       Consenting Parties' right to such In Kind Penalty shall terminate, and
       such Non-Consenting Party shall own, take and dispose of its Entitlement
       from such Exploitation Area. Production from other fields in the Contract
       Area, outside such Exploitation Area shall not be used to satisfy the In
       Kind Penalty. Any obligation of the Non-Consenting Party to satisfy the
       In Kind Penalty shall terminate with the cessation of production from the
       Exploitation Area (or well, as the case may be) which the In Kind Penalty
       encumbers.

       (C) Within ninety (90) Days after the Completion of any Exclusive
       Operation, the Operator shall furnish to each NonConsenting Party that
       has granted an In Kind Penalty in respect of such Exclusive Operation an
       inventory of the equipment in and connected to the well, and an itemized
       statement of the cost of such Exclusive Operation, including equipping
       the well for production. Each Calendar Quarter during the period of
       satisfying an In Kind Penalty, Operator

                                       58
<PAGE>
       shall furnish to the Non-Consenting Parties that have granted such In
       Kind Penalty an itemized statement of all costs and liabilities incurred
       in the Exclusive Operation(s), establishing the value of such In Kind
       Penalty together with a statement of the quantity of Hydrocarbons
       produced to satisfy such In Kind Penalty and the amount of proceeds
       realized from the sale of such production during the preceding Calendar
       Quarter.

       (D) In determining the quantity of Hydrocarbons produced for purposes of
       the In Kind Penalty, the Consenting Parties shall use industry accepted
       methods such as but not limited to metering or periodic well tests.

       (E) During the period of time Consenting Parties are entitled to an In
       Kind Penalty, such Consenting Parties shall be responsible for the
       payment of all royalties, charges, taxes, and all other burdens
       established by the Contract directly related to such In Kind Penalty.

       (F) Any amount realized from the sale or other disposition of equipment,
       which was acquired in connection with an Exclusive Operation, shall be
       credited against the satisfaction of the In Kind Penalty.

       (G) On satisfaction of the In Kind Penalty, the right of such
       Non-Consenting Party to own, take in kind and separately dispose of its
       Entitlement granted under Article

                                       59
<PAGE>
       7.5(C), shall be reinstated automatically as of 7:00 a.m. on the Day
       following the Day on which such satisfaction occurs.

7.6    ORDER OF PREFERENCE OF OPERATIONS

       (A) Except as otherwise specifically provided in this Agreement, if any
       Party desires to propose the conduct of an operation that will conflict
       with an existing proposal for an Exclusive Operation, such Party shall
       have the right exercisable for five (5) Days, or forty-eight (48) hours
       if the drilling rig to be used is standing by in the Contract Area, from
       receipt of the proposal for the Exclusive Operation, to deliver to all
       Parties entitled to participate in the proposed operation such Party's
       alternative proposal. Such alternative proposal shall contain the
       information required under Article 7.2(A).

       (B) Each Party receiving such proposals shall elect by delivery of notice
       to Operator within the appropriate response period set out in Article
       7.2(B) to participate in one of the competing proposals. Any Party not
       notifying Operator within the response period shall be deemed not to have
       voted.

       (C) The proposal receiving the largest aggregate Participating Interest
       vote shall have priority over all other competing proposals. In the case
       of a tie vote, the

                                       60
<PAGE>
       Operator shall choose among the proposals receiving the largest aggregate
       Participating Interest vote. Operator shall deliver notice of such result
       to all Parties entitled to participate in the operation within five (5)
       Days of the end of the response period, or forty-eight (48) hours if the
       drilling rig to be used is standing by in the Contract Area.

       (D) Each Party shall then have two (2) Days (or forty-eight (48) hours if
       the drilling rig to be used is standing by in the Contract Area) from
       receipt of such notice to elect by delivery of notice to Operator whether
       such Party will participate in such Exclusive Operation, or will
       relinquish its interest pursuant to Article 7.4(B). Failure by a Party to
       deliver such notice within such period shall be deemed an election not to
       participate in the prevailing proposal.

7.7    STAND-BY COSTS

       (A) When an operation has been performed, all tests have been conducted
       and the results of such tests furnished to the Parties, stand by costs
       incurred pending response to any Party's notice proposing an Exclusive
       Operation for Deepening, Testing, Sidetracking, Completing, Plugging
       Back, Recompleting, Reworking or other further operation in such well
       (including the period required under Article 7.6 to resolve competing
       proposals) shall be charged and borne as part of the operation just
       completed. Stand by costs

                                       61
<PAGE>
       incurred subsequent to all Parties responding, or expiration of the
       response time permitted, whichever first occurs, shall be charged to and
       borne by the Parties proposing the Exclusive Operation in proportion to
       their Participating Interests, regardless of whether such Exclusive
       Operation is actually conducted.

       (B) If a further operation is proposed while the drilling rig to be
       utilized is on location, any Party may request and receive up to five (5)
       additional Days after expiration of the applicable response period
       specified in Article 7.2(B) within which to respond by notifying Operator
       that such Party agrees to bear all stand by costs and other costs
       incurred during such extended response period. Operator may require such
       Party to pay the estimated stand by time in advance as a condition to
       extending the response period. If more than one Party requests such
       additional time to respond to the notice, stand by costs shall be
       allocated between such Parties on a Day-to-Day basis in proportion to
       their Participating Interests.

7.8    SPECIAL CONSIDERATIONS REGARDING DEEPENING

       (A) An Exclusive Well shall not be Deepened without first affording the
       Non-Consenting Parties in accordance with this Article the opportunity to
       participate in such operation.

                                       62
<PAGE>
       (B) In the event any Consenting Party desires to Deepen an Exclusive
       Well, such Party shall initiate the procedure contemplated by Article
       7.2. If a Deepening operation is approved pursuant to such provisions,
       and if any NonConsenting Party to the Exclusive Well elects to
       participate in such Deepening operation, the payment, if any, pursuant to
       Article 7.5 of such Non-Consenting Party shall be calculated based on the
       following liabilities and expenses:

              (1) If the proposal is to Deepen and is made prior to the
              Completion of such well as a Commercial Discovery, then payment
              shall be based on such Non-Consenting Party's Participating
              Interest share of the liabilities and expenses incurred in
              connection with drilling the Exclusive Well from the surface to
              the depth previously drilled which such Non-Consenting Party would
              have paid had such Non-Consenting Party agreed to participate in
              such Exclusive Well, plus the Non-Consenting Party's Participating
              Interest share of the liabilities and expenses of Deepening and of
              participating in any further operations on such Exclusive Well in
              accordance with the other provisions of this Agreement; provided,
              however, all liabilities and expenses for Testing and Completing
              or attempting Completion of the well incurred

                                       63
<PAGE>
              by Consenting Parties prior to the commencement of actual
              operations to Deepen beyond the depth previously drilled shall be
              for the sole account of Consenting Parties in the proportion their
              Participating Interest bears to the aggregate of their
              Participating Interests.

              (2) If the proposal is to Deepen and is made for an Exclusive Well
              that has been previously Completed as a Commercial Discovery, but
              is no longer producing, then payment shall be based on the
              Non-Consenting Party's Participating Interest share of all costs
              of drilling and Completing said well from the surface to the depth
              previously drilled, calculated in the manner provided in Article
              7.8(B)(1), less those costs recouped by the Consenting Parties
              from the sale of production from such Exclusive Well, plus the
              Non-Consenting Party's Participating Interest share of all costs
              of reentering said well, plus the Non-Consenting Party's
              proportionate part (based on the percentage of the Exclusive Well
              such Non-Consenting Party would have owned had it previously
              participated in such Exclusive Well) of the costs of salvable
              materials and equipment remaining in the hole and salvable surface
              equipment used in connection with such well shall be determined in
              accordance with the

                                       64
<PAGE>
              Accounting Procedure. If at the time such Deepening operation is
              conducted the Consenting Parties have recouped from the Exclusive
              Well the amount calculated pursuant to Article 7.5, then a
              Non-Consenting Party may participate in the Deepening of the
              Exclusive Well with no payment for liabilities and expenses
              incurred prior to reentering the well for Deepening.

7.9    MISCELLANEOUS

       (A) Each Exclusive Operation shall be carried out by the Consenting
       Parties acting as the Operating Committee, subject to the provisions of
       this Agreement applied mutatis mutandis to such Exclusive Operation and
       subject to the terms and conditions of the Contract.

       (B) The computation of liabilities and expenses incurred in Exclusive
       Operations, including the liabilities and expenses of Operator for
       conducting such operations, shall be made in accordance with the
       principles set out in the Accounting Procedure.

       (C) Operator shall maintain separate books, financial records and
       accounts for Exclusive Operations which shall be subject to the same
       rights of audit and examination as the Joint Account and related records,
       all as provided in the Accounting Procedure. Said rights of audit and
       examination shall extend to each of the Consenting Parties and each of

                                       65
<PAGE>
        the Non-Consenting Parties so long as the latter are, or may be,
        entitled to elect to participate in such operations. 

       (D) Operator, if it is not a Consenting Party and it is conducting an
       Exclusive Operation for the Consenting Parties, shall be entitled to
       request cash advances and shall not be required to use its own funds to
       pay any cost and expense and shall not be obliged to commence or continue
       Exclusive Operations until cash advances requested have been made, and
       the Accounting Procedure shall apply to Operator in respect of any
       Exclusive Operations conducted by it.

       (E) Should the submission of a Development Plan be approved in accordance
       with Article 5.9, or should any Party propose a development in accordance
       with Article VII, with either proposal not calling for the conduct of
       additional appraisal drilling, and should any Party wish to drill an
       additional Appraisal Well prior to development, then the Party proposing
       the Appraisal Well as an Exclusive Operation shall be entitled to proceed
       first, but without the right to future reimbursement of costs or to any
       Penalty, pursuant to Article 7.5. If, as the result of drilling such
       Appraisal Well as an Exclusive Operation, the Party proposing to apply
       for an Exploitation Area decides to not develop the reservoir, then each
       Non-Consenting Party who voted in favor of such Development Plan prior to
       the drilling of such

                                       66
<PAGE>
       Appraisal Well shall pay to the Consenting Party the amount such
       Non-Consenting Party would have paid had such Appraisal Well been drilled
       as a Joint Operation.

       (F) In the case of any Exclusive Operation for Deepening, Testing,
       Completing, Plugging Back, Recompleting or Reworking, the Consenting
       Parties shall be permitted to use, free of cost, all casing, tubing and
       other equipment in the well, that is not needed for Joint Operations, but
       the ownership of all such equipment shall remain unchanged. On
       abandonment of a well after such Exclusive Operation, the Consenting
       Parties shall account for all such equipment to the Parties who shall
       receive their respective Participating Interest shares, in value, less
       cost of salvage.

       (G) If the Operator is a Non-Consenting Party to an Exclusive Operation
       to Develop a Discovery, then subject to obtaining any necessary
       Government approval the Operator may resign, but in any event shall
       resign on the request of the Consenting Parties, as Operator for the
       Exploitation Area for such Discovery and the Consenting Parties shall
       select a Party to serve as Operator.

                             ARTICLE VIII - DEFAULT

8.1    DEFAULT AND NOTICE

       Any Party that fails to pay when due its Participating Interest share of
       Joint Account expenses including cash

                                       67
<PAGE>
       advances and interest, accrued pursuant to this Agreement (a "Defaulting
       Party") shall be in default under this Agreement. Operator, or any other
       Party in the case of the default of Operator, shall promptly give written
       notice of such default to such Party and each of the non-defaulting
       Parties. The amount not paid by the Defaulting Party shall bear interest
       from the date due until paid in full. Interest will be calculated using
       the Agreed Interest Rate.

8.2    OPERATING COMMITTEE MEETINGS AND DATA

       After any default has continued for five (5) Business Days from the date
       of written notice of default under Article 8.1, and for as long
       thereafter as the Defaulting Party remains in default on any payment due
       under this Agreement, the Defaulting Party shall not be entitled to
       attend Operating Committee meetings or to vote on any matter coming
       before the Operating Committee during the period such default continues.
       Unless agreed otherwise by the non-defaulting Parties, the voting
       interest of each non-defaulting Party shall be in the proportion which
       its Participating Interest bears to the total of the Participating
       Interests of all the non-defaulting Parties. Any matters requiring
       unanimous vote of the Parties shall be deemed to exclude the Defaulting
       Party. After the said five

                                       68
<PAGE>
       (5) Business Days and while the Defaulting Party remains in default as
       aforesaid, the Defaulting Party shall not have access to any data or
       information relating to Joint Operations, and non-defaulting Parties
       shall be entitled to trade data without such Defaulting Party's consent
       and the Defaulting Party shall have no right to any data received on such
       trade unless and until its default is remedied in full.

       Notwithstanding the foregoing, the Defaulting Party shall be deemed to
       have approved, and shall join with the non-defaulting Parties in taking
       any action to maintain and preserve the Contract.

8.3    ALLOCATION OF DEFAULTED ACCOUNTS

       (A) Operator shall, either at the time of giving notice of default as
       provided in Article 8.1, or by separate notice, notify each
       non-defaulting Party of the sum of money it is to pay as its portion
       (such portion being in the ratio that each non-defaulting Party's
       Participating Interest bears to the Participating Interests of all
       non-defaulting Parties) of such amount in default. Each non-defaulting
       Party shall, if such default continues, pay Operator, within five (5)
       Business Days after receipt of such notice, its share of the amount which
       the Defaulting Party failed to pay. If any non-defaulting Party fails to
       pay its share of the amount in default as aforesaid, such non-defaulting
       Party shall

                                       69
<PAGE>
       thereupon be in default and shall be a Defaulting Party subject to the
       provisions of this Article. The non-defaulting Parties which pay the
       amount owed by any Defaulting Party shall be entitled to receive their
       respective share of the principal and interest payable by such Defaulting
       Party pursuant to Article 8.1.

       (B) The total of all amounts paid by the non-defaulting Parties for the
       Defaulting Party, together with interest accrued on such amounts shall
       constitute a debt due and owing by the Defaulting Party to the
       non-defaulting Parties in proportion to such amounts paid. In addition
       the non-defaulting Parties may in the manner contemplated by this
       Article, satisfy such debt (together with interest) and may accrue an
       amount equal to the Defaulting Party's Participating Interest share of
       the estimated cost to abandon any Joint Property.

       (C) A Defaulting Party may remedy its default by paying to Operator the
       total amount due, together with interest calculated as provided in
       Article 8.1, at any time prior to transfer of its interest pursuant to
       Article 8.4, and upon receipt of such payment Operator shall remit to
       each non-defaulting Party its proportionate share of such amount.

       (D) The rights granted to each non-defaulting Party pursuant to this
       Article, shall be in addition to, and not

                                       70
<PAGE>
       in substitution for any other rights or remedies which each
       non-defaulting Party may have at law or equity or pursuant to the other
       provisions of this Agreement.

8.4    TRANSFER OF INTEREST

       (A) For thirty (30) Days after each failure by the Defaulting Party to
       remedy its default by the thirtieth (30th) Day following notice of
       default without prejudice to any other rights of the non-defaulting
       Parties to recover the amounts paid for the Defaulting Party, together
       with interest accrued on such amount, each non-defaulting Party shall
       have the option to give notice to the Defaulting Party requiring the
       Defaulting Party to transfer its interest to the non-defaulting Parties.
       To that end if any of the non-defaulting Parties so elect, the Defaulting
       Party shall be deemed to have transferred and to have empowered the
       electing non-defaulting Parties to execute on said Defaulting Party's
       behalf any documents required to effect a transfer, of all of its right,
       title and beneficial interest in and under this Agreement and the
       Contract, and in all wells and Joint Property to the electing
       non-defaulting Parties. If requested, each Party shall execute a Power of
       Attorney in the form prescribed by the Operating Committee. The
       Defaulting Party shall, without delay following any request from the
       non-defaulting Parties, do any and all acts

                                       71
<PAGE>
        required to be done by applicable law or regulation in order to render
        such transfer legally valid, including, without limitation, the
        obtaining of all governmental consents and approvals, and shall execute
        any and all documents and take such other actions as may be necessary in
        order to effect prompt and valid transfer of the interests described
        above, free of all liens and encumbrances. In the event all Government
        approvals are not timely obtained, the Defaulting Party shall hold its
        Participating Interest in trust for such non-defaulting Parties who
        elected to assume such Defaulting Party's Participating Interest. 

       (B) In the absence of an agreement among the non-defaulting Parties to
       the contrary, any such transfer to the non-defaulting Parties shall be in
       the proportion that the non-defaulting Parties have paid the amounts due
       from the Defaulting Party.

       (C) Subject to Article 12.1(C), on the effective date of such transfer
       the Defaulting Party shall forthwith cease to be a Party to this
       Agreement to the extent of the Participating Interest so transferred. The
       acceptance or non-acceptance by a non-defaulting Party of any portion of
       a Defaulting Party's Participating Interest shall be without prejudice to
       any rights or remedies such non-defaulting

                                       72
<PAGE>
       Parties have to recover the outstanding debts (including interest) owed
       by the Defaulting Party.

8.5    CONTINUATION OF INTEREST

       If within thirty (30) Days after each failure by the Defaulting Party to
       remedy its default by the thirtieth (30th) Day following notice of
       default the non-defaulting Parties elect to not acquire the Defaulting
       Party's Participating Interest as provided in Article 8.4 and to continue
       to bear the Defaulting Party's Participating Interest share of
       liabilities and expenses, then the non-defaulting Parties shall
       accumulate all such liabilities and expenses as a debt pursuant to
       Article VIII, but the Defaulting Party shall continue to be a Party
       subject to Article 8.2 and Article 8.7. If Operator disposes of any Joint
       Property or any other credit or adjustment is made to the Joint Account,
       or if Operator sells any of the Defaulting Party's Participating Interest
       share of Hydrocarbons, then, in respect of the Defaulting Party's
       Participating Interest share of the proceeds of such disposal, credit or
       adjustment or sale, Operator shall be entitled to retain and to set off
       the same against all amounts, together with interest accrued on such
       amount, due and owing from the Defaulting Party plus an accrued amount
       equal to the Defaulting Party's Participating Interest share

                                       73
<PAGE>
       of the estimated cost to abandon any Joint Property. Any surplus
       remaining after setting off the same as aforesaid shall be paid promptly
       to the Defaulting Party.

8.6    ABANDONMENT

       If, within thirty (30) Days after the failure by the Defaulting Party to
       remedy its default by the thirtieth (30th) Day as aforesaid, no
       non-defaulting Party elects to acquire the Defaulting Party's
       Participating Interest as provided in Article 8.4, or to bear the
       Defaulting Party's Participating Interest share of liabilities and
       expenses as provided in Article 8.5, then no transfer shall be made and
       Joint Operations shall be abandoned subject to any necessary consents and
       notices being given, and each Party, including the Defaulting Party shall
       pay its Participating Interest share of all costs of abandoning and
       relinquishing the Contract. If abandonment occurs as aforesaid, all
       monies paid by the non-defaulting Parties for the Defaulting Party
       pursuant to Article 8.3, together with interest accrued on such amount,
       shall remain a debt due and owing by the Defaulting Party.

8.7    SALE OF HYDROCARBONS

       If a Party defaults after the commencement of commercial production and
       has not remedied the default by the thirtieth (30th) Day as aforesaid,
       then, during the

                                       74
<PAGE>
       continuance of such default, the Defaulting Party shall not be entitled
       to its Participating Interest share of Hydrocarbons which shall vest in
       and be the property of the non-defaulting Parties, and Operator shall be
       authorized to sell such Hydrocarbons at the best price obtainable under
       the circumstances and, after deducting all costs, charges and expenses
       incurred by Operator in connection with such sale, pay the proceeds
       proportionately to the non-defaulting Parties which proceeds shall be
       credited against all monies advanced pursuant to Article 8.3, together
       with interest accrued thereon. Any surplus remaining shall be paid to the
       Defaulting Party, and any deficiency shall remain a debt due from the
       Defaulting Party to the non-defaulting Parties. Notwithstanding any such
       sales by Operator, the provisions of Article 8.4 shall continue to apply.

8.8    NO RIGHT OF SET OFF

       Each Party acknowledges and accepts that a fundamental principle of this
       Agreement is that each Party pays its Participating Interest share of all
       amounts due under this Agreement as and when required. Accordingly, any
       Party which becomes a Defaulting Party undertakes that, in respect of
       either any exercise by the non-defaulting Parties of any rights under or
       the application of any of the provisions of this Article, such Party
       shall not raise by way of set off

                                       75
<PAGE>
       or invoke as a defense, whether in law or equity, any failure to pay
       amounts due and owing under this Agreement or any alleged or unliquidated
       claim that such Party may have against Operator or any Non-Operator,
       whether such claim arises under this Agreement or otherwise. Such Party
       further undertakes not to raise by way of defense, whether in law or in
       equity, that the nature or the amount of the remedies granted to the
       non-defaulting Parties is unreasonable or excessive.

                     ARTICLE IX - DISPOSITION OF PRODUCTION

9.1    RIGHT AND OBLIGATION TO TAKE IN KIND

       Except as otherwise provided in this Article, each Party shall have the
       right and obligation to own, take in kind and separately dispose of its
       Participating Interest share of total production available to the Parties
       pursuant to the Contract from any Exploitation Area in such quantities
       and in accordance with such procedures as may be set forth in the offtake
       agreement referred to in Article 9.2 or in the special arrangements for
       natural gas referred to in Article 9.3. If Government Oil Company is
       party to the offtake agreement, then the Parties shall endeavor to obtain
       its agreement to the principles set forth in this Article.

9.2    OFFTAKE AGREEMENT FOR CRUDE OIL

                                       76
<PAGE>
       If crude oil is to be produced from an Exploitation Area, the Parties
       shall in good faith, and not less than three (3) months prior to first
       delivery of crude oil, negotiate and conclude the terms of an agreement
       to cover the offtake of crude oil produced under the Contract. The
       Government Oil Company may, if necessary and practicable, also be party
       to the offtake agreement. This offtake agreement shall, to the extent
       consistent with the Contract, make provision for:

              (A) The delivery point, at which title and risk of loss of
              Participating Interest shares of crude oil shall pass to the
              Parties interested (or as the Parties may otherwise agree);

              (B) Operator's regular periodic advice to the Parties of estimates
              of total available production for suc ceeding periods,
              Participating Interest shares, and grades of crude oil for as far
              ahead as is necessary for Operator and the Parties to plan offtake
              arrangements. Such advice shall also cover for each grade of crude
              oil total available production and deliveries for the preceding
              period, inventory and overlifts and underlifts;

              (C) Nomination by the Parties to Operator of acceptance of their
              Participating Interest share of

                                       77
<PAGE>
              total available production for the succeeding period. Such
              nominations shall in any one period be for each Party's entire
              Participating Interest share arising during that period subject to
              operational tolerances and agreed minimum economic cargo sizes or
              as the Parties may otherwise agree;

              (D) Elimination of overlifts and underlifts;

              (E) If offshore loading or a shore terminal for vessel loading is
              involved, risks regarding acceptability of tankers, demurrage and
              (if applicable) availability of berths;

              (F) Distribution to the Parties of Entitlements to ensure, to the
              extent Parties take delivery of their Entitlements in proportion
              to the accrual of such Entitlements, that each Party shall receive
              currently Entitlements of grades, gravities and qualities of
              Hydrocarbons similar to Hydrocarbons received by each other Party.

              (G) To the extent that distribution of Entitlements on such basis
              is impracticable due to availability of facilities and minimum
              cargo sizes, a method of making periodic adjustments; and

              (H) The option and the right of the other Parties to sell an
              Entitlement which a Party fails to nominate for

                                       78
<PAGE>
              acceptance pursuant to (C) above or of which a Party fails to take
              delivery, in accordance with applicable agreed procedures,
              provided that such failure either constitutes a breach of
              Operator's or Parties' obligations under the terms of the
              Contract, or is likely to result in the curtailment or shut-in of
              production. Such sales shall be made only to the limited extent
              necessary to avoid disruption in Joint Operations. Operator shall
              give all Parties as much notice as is practicable of such
              situation and that a sale option has arisen. Any sale shall be of
              the unnominated or undelivered Entitlement as the case may be and
              for reasonable periods of time as are consistent with the minimum
              needs of the industry and in no event to exceed twelve (12)
              months. The right of sale shall be revocable at will subject to
              any prior contractual commitments. Sales to non-affiliated third
              parties shall be for the realized price f.o.b. the delivery point.
              Sales to any of the Parties or their Affiliates shall be at
              current market value f.o.b. the delivery point. The Party
              arranging the sale shall pay to the Party whose Entitlement is
              involved the above price after deduction of all costs, including
              storage costs, incurred in respect of such sale, reflecting actual

                                       79
<PAGE>
              costs of disposal at immediate notice. Current market value shall
              be the value of the Entitlement in international markets (unless
              the Entitlement was required to be delivered into the Government's
              domestic market, in which case it shall be the value therein)
              between a willing buyer and a willing seller and shall be agreed
              between the two Parties concerned, or failing agreement,
              determined by an expert to be appointed in accordance with
              procedures set forth in the offtake agreement.

9.3    SEPARATE AGREEMENT FOR NATURAL GAS

       The Parties recognize that if natural gas is discovered it may be
       necessary for the Parties to enter into special arrangements for the
       disposal of the natural gas, which are consistent with the Development
       Plan and subject to the terms of the Contract.

                        ARTICLE X - ABANDONMENT OF WELLS

10.1   ABANDONMENT OF WELLS DRILLED AS JOINT OPERATIONS

       (A) Any well which has been drilled as a Joint Operation and which is
       proposed to be plugged and abandoned shall not be plugged and abandoned
       without the consent of all Parties.

                                       80
<PAGE>
       (B) Should any such Party fail to reply within the period prescribed in
       Article 5.12(A)(1) or Article 5.12(A)(2), whichever is applicable, after
       delivery of notice of the Operator's proposal to plug and abandon such
       well, such Party shall be deemed to have consented to the proposed
       abandonment. If all the Parties consent to abandonment, such well shall
       be plugged and abandoned in accordance with applicable regulations and at
       the cost, risk and expense of the Parties who participated in the cost of
       drilling such well.

       (C) If all Parties do not agree to the abandonment of such well, those
       wishing to continue operations shall assume financial responsibility over
       the well and shall be deemed to be Consenting Parties conducting an
       Exclusive Operation pursuant to Article VII. In the case of a producing
       well, the Consenting Parties shall be entitled to continue producing only
       from the Zone open to production at the time they assumed responsibility
       for the well.

       (D) Consenting Parties taking over a well as provided above shall tender
       to each of the Non-Consenting Parties such NonConsenting Parties'
       Participating Interest share of the value of the well's salvable material
       and equipment, determined in accordance with the Accounting Procedure,
       less the estimated cost of salvaging and the estimated cost of

                                       81
<PAGE>
        plugging and abandoning as of the date the Consenting Party assumed
        responsibility for the well; provided, however, that in the event the
        estimated cost of plugging and abandoning and the estimated cost of
        salvaging are higher than the value of the well's salvable material and
        equipment, each of the abandoning Parties shall continue to be liable
        pursuant to Article 7.3(B) for their respective Participating Interest
        shares of the estimated excess cost. 

       (E) Each Non-Consenting Party shall be deemed to have relinquished to the
       Consenting Parties in proportion to their Participating Interests all of
       its interest in the wellbore of a produced well and related equipment in
       accordance with Article 7.4(B), insofar and only insofar as such interest
       covers the right to obtain production from that wellbore in the Zone then
       open to production.

       (F) Subject to Article 7.9(G), Operator shall continue to operate a
       produced well for the account of the Consenting Parties at the rates and
       charges contemplated by this Agreement, plus any additional cost and
       charges which may arise as the result of the separate allocation of
       interest in such well.

10.2   ABANDONMENT OF EXCLUSIVE OPERATIONS

       This Article shall apply mutatis mutandis to the abandonment of an
       Exclusive Well or any well in which an

                                       82
<PAGE>
       Exclusive Operation has been conducted; provided that no well shall be
       permanently plugged and abandoned unless and until all Parties having the
       right to conduct further operations in such well have been notified of
       the proposed abandonment and afforded the opportunity to elect to take
       over the well in accordance with the provisions of this Article X.

                 ARTICLE XI - SURRENDER, EXTENSIONS AND RENEWALS

11.1   SURRENDER

       (A) If the Contract requires the Parties to surrender any portion of the
       Contract Area, Operator shall advise the Operating Committee of such
       requirement at least one hundred and twenty (120) Days in advance of the
       earlier of the date for filing irrevocable notice of such surrender or
       the date of such surrender. Prior to the end of such period, the
       Operating Committee shall determine pursuant to Article V, the size and
       shape of the surrendered area, consistent with the requirements of the
       Contract. If a sufficient vote of the Operating Committee cannot be
       attained, then the proposal supported by a simple majority of the
       Participating Interests shall be adopted. If no proposal attains the
       support of a simple majority of the Participating Interests, then the
       proposal receiving the largest aggregate Participating Interest vote
       shall be adopted. In the event

                                       83
<PAGE>
       of a tie, the Operator shall choose among the proposals receiving the
       largest aggregate Participating Interest vote. The Parties shall execute
       any and all documents and take such other actions as may be necessary to
       effect the surrender. Each Party renounces all claims and causes of
       action against Operator and any other Parties on account of any area
       surrendered in accordance with the foregoing but against its
       recommendation if Hydrocarbons are subsequently discovered under the
       surrendered area.

       (B) A surrender of all or any part of the Contract Area which is not
       required by the Contract shall require the unanimous consent of the
       Parties.

11.2   EXTENSION OF THE TERM

       (A) A proposal by any Party to extend the term of the Exploration or
       Exploitation Period or any phase of the Contract, a proposal to enter
       into a new phase of the Exploration Period, and a proposal to extend the
       term of the Contract shall be brought before the Operating Committee
       pursuant to Article V.

                                       84
<PAGE>
       (B) Any Party shall have the right to extend the term of the Exploration
       or Exploitation Period or any phase of the Contract to enter into a new
       phase of the Exploration Period or extend the term of the Contract to the
       extent provided in the Contract. Any Party not wishing to extend, shall
       have a right to withdraw, subject to the requirements of Article XIII.

       (C) The Contract shall not be modified, or a new contract shall not be
       entered into, without a written agreement duly executed by all Parties.

                  ARTICLE XII - TRANSFER OF INTEREST OR RIGHTS

12.1   OBLIGATIONS

       (A) Subject always to the requirements of the Contract, the transfer of
       all or part of a Party's Participating Interest shall be effective only
       if it satisfies the terms and conditions of this Article.

       (B) Except in the case of a Party transferring all of its Participating
       Interest, no transfer shall be made by any Party which results in the
       transferor or the transferee holding a Participating Interest of less
       than ten percent (10%) or holding any Interest other than a Participating
       Interest in the Contract, the Contract Area and this Agreement.

                                       85
<PAGE>
       (C) The transferring Party shall, notwithstanding the transfer, be liable
       to the other Parties for any obligations, financial or otherwise, which
       have vested, matured or accrued under the provision of the Contract or
       this Agreement prior to such transfer. Such obligations shall include,
       without limitation, any proposed expenditure approved by the Operating
       Committee, prior to the transferring Party notifying the other Parties of
       its proposed transfer.

       (D) The transferee shall have no rights in and under the Contract, the
       Contract Area or this Agreement unless and until it obtains any necessary
       Government or Government Oil Company approval and expressly undertakes in
       writing to perform the obligations of the transferor under the Contract
       and this Agreement in respect of the Participating Interest being
       transferred, to the satisfaction of the Parties and furnishes any
       guarantees required by the Government or the Contract.

       (E) The transferee shall have no rights in and under the Contract, the
       Contract Area or this Agreement unless each Party has consented in
       writing to such transfer, which consent shall be denied only if such
       transferee fails to establish to the reasonable satisfaction of each
       Party its

                                       86
<PAGE>
       financial or technical capability to perform its obligations under the
       Contract and this Agreement.

       (F) Nothing contained in this Article shall prevent a Party from
       mortgaging, pledging, charging or otherwise encumbering all or part of
       its interest in the Contract Area and in and under this Agreement for the
       purpose of security relating to finance provided that:

              (1) such Party shall remain liable for all obligations relating to
              such interest;

              (2) the encumbrance shall be subject to any necessary approval of
              the Government and be expressly subordinated to the rights of the
              other Parties under this Agreement; and

              (3) such Party shall ensure that any such mortgage, pledge, charge
              or encumbrance shall be expressed to be without prejudice to the
              provisions of this Agreement.

       (G) Notwithstanding the foregoing, a Party may transfer all or a part of
       its Participating Interest to an Affiliate of that Party. Such transfer
       shall be effective only upon the transferor furnishing to the Parties a
       guarantee of the obligations of the transferee, in a form satisfactory to
       the other Parties.

12.2   RIGHTS

                                       87

       12.1, to freely transfer its Participating Interest.

                    ARTICLE XIII - WITHDRAWAL FROM AGREEMENT

13.1   RIGHT OF WITHDRAWAL

       (A) Subject to the provisions of this Article, any Party may withdraw
       from this Agreement and the Contract by giving notice to all other
       Parties stating its decision to withdraw and specifying a proposed
       effective date of withdrawal which shall be at least sixty (60) Days, but
       not more than one hundred eighty (180) Days after the date of such
       notice. Such notice shall be unconditional and irrevocable when given.

       (B) Notwithstanding Article 13.1(A) a Party shall not have the right to
       withdraw from this Agreement and the Contract until the Minimum Work
       Obligation set forth in the Contract has been fulfilled. However, if the
       Operating Committee or any Party decides to accept new Minimum Work
       Obligations by voluntarily extending the current or entering into a new
       exploration period under the Contract, a Party that voted against such
       decision shall not be prevented from withdrawing; provided that such
       Party delivers notice of its withdrawal to all Parties within thirty (30)
       Days of such

                                       88
<PAGE>
       vote pursuant to Article 11.2 and fully satisfies its outstanding Minimum
       Work Obligation, if any.

       (C) Subject to Articles 13.1(A) and (B) and Article 13.5, the effective
       date of withdrawal for a withdrawing Party shall be the later of:

              (1) The date proposed in the notice of withdrawal; or

              (2) The date that the withdrawing Party has fulfilled its
              obligations under this Article.

13.2   PARTIAL OR COMPLETE WITHDRAWAL

       (A) Within thirty (30) Days of receipt of each withdrawing Party's
       notification, each of the other Parties may also give notice that it
       desires to withdraw from this Agreement and the Contract. Should all
       Parties give notice of withdrawal, the Parties shall proceed to abandon
       the Contract Area and terminate the Contract and this Agreement. If less
       than all of the Parties give such notice of withdrawal, then the
       withdrawing Parties shall take all steps to withdraw from the Contract
       and this Agreement on the earliest possible date and execute and deliver
       all necessary instruments and documents to assign their Participating
       Interest to the Parties which are not withdrawing, without any
       compensation whatsoever, in accordance with the provisions of Article
       13.6.

                                       89
<PAGE>
       (B) If any part of the withdrawing Party's Participating Interest remains
       unclaimed after sixty (60) Days from the date of the first notice of
       withdrawal, the Parties shall be deemed to have decided to withdraw from
       the Contract and this Agreement, unless at least one Party agrees to
       accept the unclaimed Participating Interest.

       (C) Any Party withdrawing under Article 11.2 or under this Article shall
       withdraw from all exploration activities under the Contract, but not from
       any Exploitation Area, Commercial Discovery, or Discovery whether
       appraised or not, made prior to such withdrawal. Such withdrawing Party
       shall retain its rights in the Joint Property but only insofar as they
       relate to any Exploitation Area, Commercial Discovery or Discovery
       whether appraised or not, and shall abandon all other rights in the Joint
       Property.

13.3   VOTING

       After giving its notification of withdrawal, a Party shall not be
       entitled to vote on any matters coming before the Operating Committee,
       other than matters for which such Party has financial responsibility.

13.4   OBLIGATIONS AND LIABILITIES

       (A) A withdrawing Party, prior to its withdrawal, shall satisfy all
       obligations and liabilities it has incurred or attributable to it prior
       to its withdrawal, including,

                                       90
<PAGE>
       without limitation, any expenditures budgeted and/or approved by the
       Operating Committee prior to its written notification of withdrawal
       (development projects included), and any liability for acts, occurrences
       or circumstances taking place or existing prior to its withdrawal.
       Furthermore, any liens, charges and other encumbrances which the
       withdrawing Party placed on such Party's Participating Interest prior to
       its withdrawal shall be fully satisfied or released, at the withdrawing
       Party's expense, prior to its withdrawal. A Party's withdrawal shall not
       relieve it from liability to the non-withdrawing Parties with respect to
       any obligations or liabilities attributable to the withdrawing Party
       which are not identified or identifiable at the time of withdrawal.

                                       91
<PAGE>
       (B) Notwithstanding the foregoing, a Party shall not be liable for any
       operations or expenditures it voted against if it sends notification of
       its withdrawal within five (5) Days (or within twenty-four (24) hours if
       the drilling rig to be used in such operation is standing by on the
       Contract Area) of the Operating Committee vote approving such operation
       or expenditure, nor shall such Party be liable for any operations or
       expenditures approved by the Operating Committee, excluding those
       approved pursuant to Article 13.5, after notice has been given pursuant
       to Article 13.1.

13.5   EMERGENCY

       A Party's notification of withdrawal shall not become effective if prior

       This Agreement shall be governed by, construed, interpreted and applied
       in accordance with the laws of New

                                      102

       matter to the laws of another jurisdiction.

<PAGE>
18.2   DISPUTE RESOLUTION

       (A) Any dispute, controversy or claim arising out of or relating to this
       contract, or the breach, termination or invalidity thereof, shall be
       settled by arbitration in accordance with the UNCITRAL Arbitration Rules
       (the "Rules") as at present in force.

       (B) The arbitration shall be heard and determined by three (3)
       arbitrators. Each side shall appoint an arbitrator of its own choice
       within ten (10) days of the submission of a Notice of Arbitration. The
       party-appointed arbitrators shall in turn appoint a presiding arbitrator
       of the tribunal within ten (10) days following the appointment of the
       arbitrators. If the party-appointed arbitrators cannot reach agreement on
       a presiding arbitrator of the tribunal, the appointing authority for the
       implementation of such procedure shall be the President for the time
       being of the American Arbitration Association in New York, who shall
       appoint an independent arbitrator who has no financial interest in the
       controversy. If all members of the tribunal were not to accept the
       appointment within ten (10) days after receipt of the Notice of
       Arbitration, and/or one Party refuses to appoint its party-appointed
       arbitrator within said ten (10) days period, either one of the Parties
       may require from the said President the designation of a single

                                      104
<PAGE>
       arbitrator, who has no financial interest in the controversy, to solve
       the controversy. All decisions and awards made by the arbitration
       tribunal shall be by majority vote.

       (C) The controversy may not be submitted to any court.

       (D) Unless otherwise expressly agreed in writing by the Parties to the
       arbitration proceedings:

              (1) The arbitration proceedings shall be held in New York, USA;

              (2) The arbitration proceedings shall be conducted in the English
              language and the arbitrator(s) shall be fluent in the Spanish and
              English languages;

              (3) The arbitrator(s) shall be and remain at all times wholly
              independent and impartial;

              (4) Any procedural issues not determined under the Rules shall be
              determined by the laws of the place of arbitration, except those
              laws which would refer the matter to another jurisdiction;

              (5) The cost of the arbitration proceedings (including attorney's
              fees and costs) shall be borne in the manner determined by the
              arbitrator(s);

              (6) The decision of the sole arbitrator or the decision of a
              majority of the arbitrators, as the case may be, shall be written,
              final and binding without the

                                      105
<PAGE>
              right of appeal, the sole and exclusive remedy regarding any
              claims, counterclaims, issues or accounts presented to the
              arbitrator, made as promptly paid in Dollars free of any deduction
              or offset. Any costs or fees incident to enforcing the award, up
              to the maximum extent permitted by law, will be charged against
              the Party resisting such enforcement;

              (7) Consequential, punitive or other similar damages shall not be
              allowed; provided, however, the award may include appropriate
              punitive damages where a Party has engaged in delaying and
              dilatory actions;

              (8) The award shall include interest from the date of any breach
              of violation of this Agreement, as determined by the arbitral
              award, and from the date of the award until paid in full, at the
              Agreed Interest Rate;

              (9) Judgment upon the award rendered may be entered in any court
              having jurisdiction over the person or the assets of the indebted
              Party, or application may be made to such court for a judicial
              acceptance of the award and an order of enforcement, as the case
              may be; and

              (10) Whenever the Parties are of more than one nationality, the
              single arbitrator or the presiding arbitrator, as the case may be,
              shall not be of the same

Attached to and made part of the Operating Agreement, hereinafter called the
"Agreement," effective as of the 8th day of December, 1993, by and between GHK
Company Colombia, Operator, and others, Non-operators.

                                    SECTION I

                               GENERAL PROVISIONS

1.1    PURPOSE.

       1.1.1     The purpose of this Accounting Procedure is to establish
                 equitable methods for determining charges and credits
                 applicable to operations under the Agreement which reflect the
                 costs of Joint Operations to the end that no Party shall gain
                 or lose in relation to other Parties.

                 It is intended that approval of the Work Program and Budget and
                 AFE's as provided in the Agreement shall constitute approval of
                 the rates and allocation methods used therein to currently
                 charge the Joint Account, but subject to verification by audit
                 at a later date as provided in the Accounting Procedure.

       1.1.2     The Parties agree, however, that if the methods prove unfair or
                 inequitable to Operator or Non-Operators, the Parties shall
                 meet and in good faith endeavor to agree on changes in methods
                 deemed necessary to correct any unfairness or inequity.

1.2    CONFLICT WITH AGREEMENT. In the event of a conflict between the
       provisions of this Accounting Procedure and the provisions of the
       Agreement to which this Accounting Procedure is attached, the provisions
       of the Agreement shall prevail.

       1.4.2     Operator shall maintain accounting records pertaining to Joint
                 Operations in accordance with generally accepted accounting

                 charges and credits applicable to Consenting Parties
                 shall be distinguished by an Exclusive Operation Ac
                 count.  For the purpose of determining and calculating

       1.6       PAYMENTS AND ADVANCES.

       1.6.1     Upon approval of any Work Program and Budget, if Opera
                 tor so requests, each Non-Operator shall advance its
                 share of estimated cash requirements for the succeeding
                 month's operations.  Each such cash call shall be equal
                 to the Operator's estimate of the money to be spent in
                 the currencies required to perform its duties under the
                 approved Work Program and Budget during the month
                 concerned.  For informational purposes the cash call
                 shall contain an estimate of the funds required for the
                 succeeding two (2) months.

       1.6.2     Each such cash call, detailed by major budget catego
                 ries, shall be made in writing and delivered to all Non-
                 Operators not less than fifteen (15) Days before the
                 payment due date.  The due date for payment of such ad
                 vances shall be set by Operator but shall be no sooner
                 than the first Business Day of the month for which the
                 advances are required.  All advances shall be made
                 without bank charges.  Any charges related to receipt of
                 advances from a Non-Operator shall be borne by that Non-
                 Operator.

       1.6.3     Each Non-Operator shall wire transfer its share of the
                 full amount of each such cash call to Operator on or
                 before the due date, in US dollars or Colombian pesos as
                 requested by Operator, and at a bank designated by
                 Operator.  If currency provided by a Non-Operator is
                 other than the requested currency, then the entire cost
                 of converting to the requested currency shall be charged
                 to that Non-Operator.

       1.6.4     Notwithstanding the provisions of Section 1.6.2, should
                 Operator be required to pay any sums of money for the
                 Joint Operations which were unforeseen at the time of
                 providing the Non-Operators with said estimates of its
                 requirements, Operator may make a written request of the
                 Non-Operators for special advances covering the Non-
                 Operators' share of such payments.  Each such Non-

                 Operator shall make its proportional special advances within
                 fifteen (15) Days after receipt of such notice.

       1.6.5     If a Non-Operator's advances exceed its share of cash
                 expenditures, the next succeeding cash advance require
                 ments, after such determination, shall be reduced
                 accordingly.  A Non-Operator may request that its excess
                 advances be refunded.  Operator shall make such refund
                 within ten (10) Days after receipt of the Non-Operator's
                 request provided that the amount is in excess of the
                 requesting Non-Operator's share of the cash advance
                 requirements for the succeeding month.

       1.6.6     If Non-Operator's advances are less than its share of cash
                 expenditures, the deficiency shall, at Operator's option, be
                 added to subsequent cash advance requirements or be paid by
                 Non-Operator within fifteen (15) Days following the receipt of
                 Operator's billing to Non- Operator for such deficiency.

       1.6.7     If, under the provisions of the Agreement, Operator is
                 required to segregate funds received from the Parties,
                 any interest received on such funds shall be applied
                 against the next succeeding cash call or, if directed by
                 the Operating Committee, distributed quarterly.  The
                 interest thus received shall be allocated to the Parties
                 on an equitable basis taking into consideration date of
                 funding by each Party to the accounts in proportion to
                 the total funding into the account.  A monthly statement
                 summarizing receipts, disbursements, transfers to each
                 joint bank account and beginning and ending balances
                 thereof shall be provided by Operator to the Parties.


       1.6.8     If Operator does not request Non-Operators to advance their
                 share of estimated cash requirements, each Non- Operator shall
                 pay its share of cash expenditures within fifteen (15) Days
                 following receipt of Operator's billing.

       1.6.9     Payments of advances or billings shall be made on or before the
                 due date. If these payments are not received by the due date
                 the unpaid balance shall bear and accrue interest from the due
                 date until the payment is received by Operator at the Agreed
                 Interest Rate. For the purpose of determining the unpaid
                 balance and interest owed, Operator shall translate to U.S.
                 currency all amounts owed in other currencies using the
                 currency exchange rate readily available to Operator at the
                 close of the last Business Day prior to the due date for the
                 unpaid balance as quoted by the applicable authority identified
                 in Section 1.4.3 of this Section I.

       1.6.10    Subject to governmental regulation, Operator shall have the
                 right, at any time and from time to time, to convert the funds
                 advanced or any part thereof to other currencies to the extent
                 that such currencies are then required for operations. The cost
                 of any such conver sion shall be charged to the Joint Account.

       1.6.11    Operator shall maintain funds held for the Joint Account in
                 bank accounts at a level consistent with that required for the
                 prudent conduct of Joint Operations.

       1.6.12    If under the Agreement, Operator is required to segre gate
                 funds received from or for the Joint Account, the provisions
                 under this Section 1.6 for payments and advances by
                 Non-Operators shall apply also to Operator.

1.7    ADJUSTMENTS. Payments of any advances or billings shall not prejudice the
       right of any Non-Operator to protest or question the correctness thereof;
       provided, however, all bills and statements rendered to Non-Operators by
       Operator during any Calendar Year shall conclusively be presumed to be
       true and correct after twenty-four (24) months following the end of such
       Calendar Year, unless within the said twenty-four (24) month period a
       Non-Oper ator takes written exception thereto and makes claim on Operator
       for adjustment. Failure on the part of a 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 claims for adjustment thereon. No adjustment favorable
       to Operator shall be made unless it is made within the same prescribed
       period. The provisions of this paragraph shall not prevent adjustments
       resulting from a physical inventory of the Property as provided for in
       Section VI. Operator shall be allowed to make adjustments to the Joint
       Account after such twenty-four (24) month period if these adjustments
       result from audit exceptions outside of this Agreement, third party
       claims, or Government or Government Oil Company requirements. Any such
       adjustments shall be subject to audit within the time period specified in
       Section 1.8.1.

1.8    AUDITS.

       1.8.1     A Non-Operator, upon at least sixty (60) Days advance
                 notice in writing to Operator and all other Non-Opera
                 tors, shall have the right to audit the Joint Accounts
                 and records of Operator relating to the accounting here
                 under for any Calendar Year within the twenty-four (24)
                 month period following the end of such Calendar Year.
                 The cost of each such audit shall be borne by Non-
                 Operators conducting the audit.  It is provided,
                 however, that Non-Operators must take written exception
                 to and make claim upon the Operator for all discrepan
                 cies 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.  Operator and Non-Operators shall make
                 every effort to resolve any claim resulting from an
                 audit within a reasonable period of time.

                 A Non-Operator may audit the records of an Affiliate of
                 Operator relating to that Affiliate's charges. The provisions
                 of this Accounting Procedure shall apply MUTATIS MUTANDIS to

                 provisions of this Section 1.8 which does not relate

                 Agreement.

                 employ a public accounting firm to audit the Joint
                 Account and records of Operator relating to the ac
                 counting hereunder, the cost thereof shall be a charge
                 against the Joint Account, and a copy of the audit shall
                 be furnished to each Party.  On the contrary, audits
                 required to be conducted either to the Operator's or to
                 any of the non-Operator's records, not directly and
                 specifically related to the Joint Operations, shall be
                 borne and paid by the audited company.

1.9    ALLOCATIONS. If it becomes necessary to allocate any costs or
       expenditures to or between Joint Operations and any other opera tions,
       such allocation shall be made on an equitable basis. Upon request,
       Operator shall furnish a description of its allocation procedures
       pertaining to these costs and expenditures.

Operator shall charge the Joint Account with all costs and expenditures incurred
in connection with Joint Operations. It is also understood that charges for
services normally provided by an operator such as those contemplated in Section
2.7.2 which are provided by Operator's Affiliates shall reflect the cost to the
Affiliate, excluding profit, for performing such services, except as otherwise
provided in Section 2.6, Section 2.7.1, and Section 2.5.1 if selected.

The costs and expenditures shall be recorded as required for the settle ment of
accounts between the Parties hereto in connection with the rights and
obligations under this Agreement and for purposes of complying with the tax laws
of the Country of Operations and of such other countries to which any of the
Parties may be subject. Without in any way limiting the generality of the
foregoing, chargeable costs and expenditures shall include:

2.1    LICENSES, PERMITS, ETC. All costs, if any, attributable to the
       acquisition, maintenance, renewal or relinquishment of licenses, permits,
       contractual and/or surface rights acquired for Joint Operations and
       bonuses paid in accordance with the Contract when paid by Operator in
       accordance with the provisions of the Agreement.

2.2    SALARIES, WAGES AND RELATED COSTS.

       2.2.1     The employees of Operator and its Affiliates in the Country of
                 Operations directly engaged in Joint Opera tions whether

                 included in salaries and wages, the Joint Account shall also be
                 charged with the cost to Operator of holiday, vacation,
                 sickness, disability benefits, living and housing allowances,
                 travel time, and other customary allowances applicable to the

                 hospitalization, retirement, and other benefit plans of a like
                 nature applicable to labor costs of Operator. Operator's
                 employees participating in Country of Opera tions benefit plans
                 may be charged at a percentage rate to reflect payments or
                 accruals made by Operator appli cable to such employees. Such
                 accruals for Country of Operations benefit plans shall not be
                 paid by Non- Operators, unless otherwise approved by the
                 Operating Committee, until the same are due and payable to the
                 employee, upon withdrawal of a Party pursuant to the Agreement,
                 or upon termination of the Agreement, which ever occurs first.

       2.2.4     Expenditures or contributions made pursuant to assess ments
                 imposed by governmental authority for payments with respect

                 usual practice, when and as paid or accrued, or on a
                 basis of the Operator's average cost per employee for
                 each job category; and the rates to be charged shall be
                 initially determined by the Operating Committee and
                 reviewed at least annually to reflect the Operator's
                 actual costs.  In determining the average cost per
                 employee for each job category, expatriate and national
                 employee salaries and wages shall be calculated
                 separately.  During a given period of time it is
                 understood that some costs for salaries and wages may be
                 charged on an actual basis while the remaining costs for
                 salaries and wages are charged at a rate based upon the
                 above described average cost

                 for which expenses the employees are reimbursed under the usual
                 practice of Operator.

       2.2.7     If employees are engaged in other activities in addition to the
                 Joint Operations, the cost of such employees shall be allocated
                 on an equitable basis.

                 Joint Operations.  If such employee works on other
                 activities in addition to Joint Operations, such relo

                 another location classified as a foreign location by Operator
                 shall not be chargeable to the Joint Account unless such
                 foreign location is the point of origin of the employee.

                                INDIRECT CHARGES

3.1    PURPOSE. Operator shall charge the Joint Account monthly for the cost of
       indirect services and related office costs of Operator and its Affiliates
       not otherwise provided in this Accounting Procedure. Indirect costs
       chargeable under this Section III represent the cost of general
       counseling and support services provided to Operator by its Affiliate.
       These costs are such that it is not practical to identify or associate
       them with specific projects but are for services which provide Operator
       with needed and necessary resources which Operator requires and provide a
       real benefit to Joint Operations. No cost or expenditure included under
       Section II shall be included or duplicated under this Section III.

3.2    AMOUNT. The charge for the period beginning with the Calendar Year
       through the end of the period covered by Operator's invoice
       ("Year-to-Date") under Section 3.1 above shall be a percentage of the
       Year-to-Date expenditures, calculated on the following scale (U.S.
       Dollars):

                               ANNUAL EXPENDITURES

                      $0 to $2,000,000 of expenditures = 3%

                      Next $3,000,000 of expenditures = 2%

                  Excess above $5,000,000 of expenditures = 1%

          A minimum amount of U.S.$120,000 shall be assessed each year.

3.3    EXCLUSIONS. The expenditures used to calculate the monthly indi rect
       charge shall not include the indirect charge (calculated either as a
       percentage of expenditures or as a minimum monthly charge), rentals on
       surface rights acquired and maintained for the Joint Account, guarantee
       deposits, pipeline tariffs, concession

       acquisition costs, bonuses paid in accordance with the Contract,
       royalties and taxes paid under the Contract, expenditures associated with
       major construction projects for which a separate indirect charge is
       established hereunder, payments to third parties in settlement of claims,
       and other similar items.

       Credits arising from any government subsidy payments, disposition of
       Material, and receipts from third parties for settlement of claims shall
       not be deducted from total expenditures in determin ing such indirect
       charge.

3.4    INDIRECT CHARGE FOR PROJECTS. As to major construction projects (such as,
       but not limited to, pipelines, gas reprocessing and processing plants,
       and final loading and terminalling facilities) when the estimated cost of
       each project amounts to more than U.S. $5,000,000, a separate indirect
       charge for such project shall be set by the Operating Committee at the
       time of approval of the project.

3.5    CHANGES. The indirect charges provided for in this Section III may be
       amended periodically by mutual agreement between the Parties if, in
       practice, these charges are found to be insufficient or excessive.

       4.2.1     NEW MATERIALS (CONDITION "1"). New Materials trans ferred from
                 the warehouse or other properties of Opera tor shall be priced

                 if Operator had purchased such new Material just prior to its
                 transfer. Such net costs shall in no event exceed the then
                 current market price.

       4.2.2     USED MATERIALS (CONDITIONS "2" AND "3").

                 4.2.2.1    Material which is in sound and serviceable condition

                            use after being repaired or reconditioned, shall be
                            classed as Condition "3" and priced at fifty percent

                            classified meet the requirements for Condition "2"
                            Material upon being repaired or reconditioned.

                 4.2.2.3    Material which cannot be classified as Con dition
                            "2" or Condition "3", shall be priced at a value
                            commensurate with its use, but not exceeding the

                            which is no longer useable for its original purpose
                            but is useable for some other purpose, shall be

                            4.2.2 of Section IV. Such Material shall be priced

       prices specified in Sections 4.1 and 4.2 of this Section IV because of
       national emergencies, strikes or other unusual causes over which Operator
       has no control, Operator may charge the Joint Account for the required
       Material at Operator's actual cost incurred procuring such Material, in
       making it suitable for use, and moving it to the Contract Area, provided
       that notice in writing, including a detailed description of the Material
       required and the required delivery date, is furnished to Non-Operators of
       the proposed charge at least 10 Days (or such shorter period as may be
       specified by Operator) before the Material is projected to be needed for
       operations and prior to billing Non-Operators for such Material the cost
       of which exceeds Twenty-five Thousand U.S. dollars (U.S. $25,000). Each
       Non-Operator shall have the right, by so electing and notifying Operator
       within 5 Days (or such shorter period as may be specified by Operator)
       after receiving notice from Operator, to furnish in kind all or part of
       his share of such Material per the terms of the notice which is suitable
       for use and acceptable to Operator both as to quality and time of
       delivery. Such acceptance by Operator shall not be unreasonably withheld.
       If Material furnished is deemed unsuitable for use by Operator, all costs
       incurred in disposing of such Material or returning Material to owner
       shall be borne by the Non-Operator furnishing the same unless otherwise
       agreed by the Parties. If a Non-Operator fails to properly submit an
       election notification within the designated period, Operator is not
       required to accept Material furnished in kind by that Non-Operator. If
       Operator fails to submit proper notification prior to billing
       Non-Operators for such Material, Operator shall only charge the Joint
       Account on the basis of the price allowed during a "normal" pricing
       period in effect at time of movement.

4.4    WARRANTY OF MATERIAL FURNISHED BY OPERATOR. Operator does not warrant the
       Material furnished. In case of defective Material, credit shall not be
       passed to the Joint Account until adjustment has been received by
       Operator from the manufacturers or their agents.

5.1    DISPOSAL. Operator shall be under no obligation to purchase the interest
       of Non-Operators in new or used surplus Materials. Operator shall have
       the right to dispose of Materials but shall advise and secure prior
       agreement of the Operating Committee of any proposed disposition of
       Materials having an original cost to the Joint Account either
       individually or in the aggregate of Twenty-five Thousand U.S. Dollars
       (U.S. $25,000) or more. When Joint Operations are relieved of Material
       charged to the Joint Account, Operator shall advise each Non-Operator of
       the original cost of such Material to the Joint Account so that the
       Parties may eliminate such costs from their asset records. Credits for
       Material sold by Operator shall be made to the Joint Account in the month
       in which payment is received for the Material. Any Material sold or
       disposed of under this Section shall be on an "as is, where is" basis
       without guarantees or warranties of any kind or nature. Costs and
       expenditures incurred by Operator in the disposition of Materials shall
       be charged to the Joint Account.

5.2    MATERIAL PURCHASED BY A PARTY OR AFFILIATE. Material purchased from the
       Joint Property by a Party or an Affiliate thereof shall be credited by
       Operator to the Joint Account, with new Material valued in the same
       manner as new Material under Section 4.2.1 and used Material valued in
       the same manner as used Material under Section 4.2.2, unless otherwise
       agreed by the Operating Committee.

5.3    DIVISION IN KIND. Division of Material in kind, if made between the
       Parties, shall be in proportion to their respective interests in such
       Material. Each Party will thereupon be charged individu ally with the
       value (determined in accordance with the procedure set forth in Section
       5.2) of the Material received or receivable by it.

5.4    SALES TO THIRD PARTIES.  Material purchased from the Joint
       Property by third parties shall be credited by Operator to the
       Joint Account at the net amount collected by Operator from the
       buyer.  If the sales price is less than that determined in

11.         INDEMNITY

11.1 Subject to Section 11.2, the Vendor will indemnify and hold harmless SSPI
from and against:

      (a)   any and all losses, damages or deficiencies resulting from any
            misrepresentation, breach of warranty or non-fulfilment of any
            covenant on the part of the Vendor under this Agreement or from any
            misrepresentation in or omission from any certificate or other
            instrument furnished or to be furnished to SSPI or SSPC hereunder;

      (b)   any and all actions, suits, proceedings, demands, assessments,
            judgments, costs and legal and other expenses incidental to any of
            the foregoing; and

      (c)   any and all liability to which SSPI or SSPC is subject as a result
            of the failure of the Vendor to pay such tax obligations of the
            Vendor as are determined to exist arising from the transactions
            contemplated herein;

and if any action or claim shall be asserted against SSPI or SSPC in respect of
which indemnity may be sought hereunder, SSPI or SSPC, as the case may be, shall
promptly notify the Vendor in writing and the Vendor shall assume the defence
thereof at his expense through legal counsel acceptable to SSPI. No party shall
effect a settlement of such action or claim without the written consent of the
other party, such consent not to be unreasonably withheld or delayed.

11.2 The maximum extent of the liability of the Vendor under Section 11.1 herein
(with the exception of liability arising directly or indirectly by reason of a
misrepresentation or breach of warranty as it relates to the representations and
warranties contained in Section 3.1(a), 3.1(d) and 3.1(ad) to 3.1(ai)) shall be
limited in the aggregate to the market value, as at the date of a claim for
indemnity, of the SSPI Preferred Shares or SSPI Shares of the Vendor, as the
case may be acquired pursuant to this Agreement and then held subject to the
Escrow Agreement as at such date, and the Vendor shall have no further personal
liability to SSPI or SSPC in this regard.

11.3 Subject to the maximum limit on liability in Section 11.2 the Vendor can
satisfy any liability referred to in Section 11.2 herein by either paying the
amount thereof to SSPI or surrendering or causing to be surrendered to SSPI such
of the Vendor's SSPI Preferred Shares or SSPI Shares or the rights thereto then
held subject to the Escrow Agreement as at the date of receipt of a claim for
indemnity as have a market value equal to the amount of the liability.

11.4 In circumstances where the Vendor is liable under Section 11.1 in respect
of a misrepresentation or breach of warranty as it relates to a representation
or warranty contained
<PAGE>
                                     - 28 -

in Sections 3.1(a), 3.1(d) and 3.1(ad) to 3.1(ai), SSPC and SSPI agree that it
shall first exhaust recourse against the SSPI Preferred Shares or SSPI Shares of
such Vendor, as the case may be, then held subject to the Escrow Agreement, to
satisfy such liability in which case the provisions of Section 11.3 apply
mutatis mutandis, and SSPI may only further seek recourse against the Vendor
generally in circumstances where the market value of such SSPI Preferred Shares
or SSPI Shares, as the case may be, is not sufficient to satisfy such liability
under Sections 3.1(a), 3.1(d) and 3.1(ad) to 3.1(aj).

11.5 For the purposes of Sections 11.2 and 11.3, herein the "market value" of
the SSPI Preferred Shares or SSPI Shares or the rights thereto shall be deemed
to be equal to the weighted average of the closing prices at which SSPI's common
shares have traded on the Alberta Stock Exchange or, if such shares are not then
listed on the Alberta Stock Exchange, on such stock exchange or electronic
trading facility on which the shares then trade as may be selected by the board
of directors of SSPI, during the 20 most recent trading days ending on the
trading day immediately prior to the date of a claim for indemnity.

11.6 SSPC and SSPI will indemnify and hold harmless the Vendor from and against:

      (a)   any and all losses, damages or deficiencies resulting from any
            misrepresentation, breach of warranty or non-fulfilment of any
            covenant on the part of SSPC or SSPI under this Agreement or from
            any misrepresentation in or omission from any certificate or other
            instrument furnished or to be furnished to the Vendor hereunder; and

      (b)   any and all actions, suits, proceedings, demands, assessments,
            judgments, costs and legal and other expenses incidental to any of
            the foregoing;

and if any action or claim shall be asserted against the Vendor in respect of
which indemnity may be sought hereunder, the Vendor shall notify SSPI in writing
and SSPI shall assume the defence thereof at its expense through legal counsel
acceptable to the Vendor. No party shall effect a settlement of such action or
claim without the written consent of the other party, such consent not to be
unreasonably withheld or delayed.

11.7 SSPI shall bear the costs relating to the test procedures in respect of the
El Segundo No. 1 well as detailed in Schedule "H". To the extent such costs
exceed the amounts set forth in Schedule "H", the Vendor, together with the
vendors under the Cimarrona Agreement and the Esmeralda Agreement, shall
reimburse SSPI for the excess pursuant to Section 11.8 hereof.

11.8 If the costs relating to the test procedures in respsct of El Segundo No 1
well exceed the amounts set forth in Schedule "H", GHK Company Colombia shall
submit invoices to the Manager (as defined in the Management Contract), SSPI and
the Vendor in respect of such excess amounts within 90 days of the date hereof.
Once satisfied that such invoices accurately reflect actual costs incurred in
respect of the test procedures, the Vendor shall within 30 days after such
90-day period pay to the Manager, and direct the Manager to pay to SSPI, a
portion of such costs equivalent to his pro rata share of the aggregate number
of warrants and preference shares in SSPI issued to the Vendor under this
Agreement and the vendors under the Cimarrona Agreement and the Esmeralda
Agreement.

11.9 The Vendor shall be entitled to a portion, equivalent to his pro rata share
of the aggregate number of warrants and preference shares in SSPI issued to the
Vendor under this Agreement and the vendors under the Cimarrona Agreement and
the Esmeralda Agreement, of any revenues generated by the production or sale of
oil produced from El Segundo No. 1 well prior to the Closing. The Vendor shall
be entitled to require from GHK Company Colombia an accounting of any such
revenues within 90 days of the date hereof and SSPI shall within 30 days after
such 90-day period pay to the Vendor the portion of such proceeds set forth in
this Section 11.9.

12.         CONTRACTUAL RIGHT OF ACTION FOR RESCISSION

12.1 In the event that the Vendor, in circumstances where he acquires the SSPI
Shares upon the conversion of the SSPI Preferred Shares as provided for in the
Final Prospectus, is or becomes entitled under applicable securities legislation
to the remedy of rescission by reason of the Final Prospectus or any amendment
thereto containing a misrepresentation, the Vendor shall be entitled to
rescission not only of the conversion of the SSPI Preferred Shares but also of
the transaction hereunder pursuant to which the SSPI Preferred Shares were
initially acquired. The foregoing is in addition to any other right or remedy
available to the Vendor under applicable securities legislation or otherwise at
law.

Montreal Trust Company of Canada to be held under the terms of the Escrow
Agreement.

            misrepresentation, breach of warranty or non-fulfilment of any
            covenant on the part of such Vendor under this Agreement or from any

      (b)   any and all actions, suits, proceedings, demands, assessments,
            judgments, costs and legal and other expenses incidental to any of
            the foregoing; and

indemnity may be sought hereunder, SSPI shall promptly notify the appropriate
Vendors in writing and the appropriate Vendors shall assume the defence thereof
at their expense through legal counsel acceptable to SSPI. No party shall effect
a settlement of such action or claim without the written consent of the other
party, such consent not to be unreasonably withheld or delayed.

individually or in the aggregate under Section 12.1 herein (with the exception
of liability arising directly or indirectly by reason of a misrepresentation or
breach of warranty as it relates to the representations and warranties contained
in Section 4.1) shall be limited in the aggregate to the market value, as at the
date of a claim for indemnity, of the SSPI Special Warrants or SSPI shares of
such Vendor, as the case may be, acquired pursuant to this Agreement and then
held subject to the Escrow Agreement as at such date, and the Vendors shall have
no further personal liability to SSPI in this regard.

12.3 In circumstances where more than one Vendor is liable under Section 12.1 as
a result of a misrepresentation or breach of warranty contained in Section 4.2,
the liability of such Vendors shall be apportioned such that each Vendor who is

<PAGE>
                                   - 25 -

such liability, limited in the aggregate as stated in Section 12.2, as is equal

to the total number of Special Warrants acquired by all the Vendors who are
liable.

12.4 Subject to the maximum limit on liability in Section 12.2, each Vendor can
satisfy any liability referred to in Section 12.2 and Section 12.3 herein by

surrendered to SSPI such of the Vendor's SSPI Special Warrants or SSPI Shares or
the rights thereto then held subject to the Escrow Agreement as at the date of
receipt of a claim for indemnity as have a market value equal to the amount of
the liability.

12.5 In circumstances where a Vendor is liable under Section 12.1 in respect of
a misrepresentation or breach of warranty as it relates to a representation or
warranty contained in Section 4.1, SSPI agrees that it shall first exhaust
recourse against the SSPI Special Warrants or SSPI Shares of such Vendor, as the
case may be, then held subject to the Escrow Agreement, to satisfy such
liability in which case the provisions of Section 12.4 apply mutatis mutandis,
and SSPI will only further seek recourse against such Vendor generally in
circumstances where the market value of such SSPI Special Warrants or SSPI
Shares, as the case may be, is not sufficient to satisfy such liability under
Section 12.1.

of the SSPI Special Warrants or SSPI shares or the rights thereto shall be

common shares have traded on the Alberta Stock Exchange or, if such shares are
not then listed on the Alberta Stock Exchange, on such stock exchange or
electronic trading facility on which the shares then trade as may be selected by
the board of directors of SSPI, during the 20 most recent trading days ending on
the trading day immediately prior to the date of a claim for indemnity.

            covenant on the part of SSPI under this Agreement or from any
            misrepresentation in or omission from any certificate or other
            instrument furnished or to be furnished to the Vendors hereunder;
            and

      (b)   any and all actions, suits, proceedings, demands, assessments,
            judgments, costs and legal and other expenses incidental to any of
            the foregoing;

and if any action or claim shall be asserted against the Vendors in respect of
which indemnity may be sought hereunder, the Vendors shall notify SSPI in
writing and SSPI shall assume the
<PAGE>
                                   - 26 -

defence thereof at its expense through legal counsel acceptable to the Vendors.

consent of the other party, such consent not to be unreasonably withheld or
delayed.

El Segundo No. 1 well as detailed in Schedule "J". To the extent such costs
exceed the amounts set forth in Schedule "J", the Vendors, together with the

1 well exceed the amounts set forth in Schedule "J", GHK Company Colombia shall
submit invoices to the Manager (as defined in the Management Contract), SSPI and
the Vendors in respect of such excess amounts within 90 days of the date hereof.
Once satisfied that such invoices accurately reflect actual costs incurred in

90-day period pay to the Manager, and direct the Manager to pay to SSPI, a
portion of such costs equivalent to their pro rata share of the aggregate number
of warrants and preference shares in SSPI issued to the Vendors under this
Agreement and the vendors under the Esmeralda Agreement and the GHK Agreement.

12.11 The Vendors shall be entitled to a portion, equivalent to their pro rata
share of the aggregate number of warrants and preference shares in SSPI issued
to the Vendors under this Agreement and the vendors under the Esmeralda
Agreement and the GHK Agreement, of any revenues generated by the production or
sale of oil produced from El Segundo No. 1 well prior to the Closing. The
Vendors shall be entitled to require from GHK Company Colombia an accounting of
any such revenues within 90 days of the date hereof and SSPI shall within 30
days after such 90-day period pay to the Vendors the portion of such proceeds
set forth in this Section 12.11.

incorporated, to be the recipient of all or any part of the SSPI Special
Warrants which are to be issued by SSPI and to which the Vendor shall be
entitled pursuant to Section 2.3 herein. Such nomination will not take effect
until communication thereof to SSPI, or to SSPI's solicitors. Once such
communication has been made, the nominee elected by such Vendor will be deemed
to be such Vendor hereunder for purposes of receiving the applicable SSPI
Special Warrants and for all purposes after the Closing Date, but the Vendor
will in no way be released from its representations, warranties and obligations
hereunder despite the election or appointment of a nominee.

12.2 The maximum extent of the liability of each of the Vendors for all claims
individually or in the aggregate under Section 12.1 herein (with the exception
of liability arising directly or indirectly by reason of a misrepresentation or
breach of warranty as it relates to the representations and warranties contained
in Section 4.1) shall be limited in the aggregate to the market value, as at the
date of a claim for indemnity, or the SSPI Special Warrants or SSPI shares of
such Vendor, as the case may be, acquired pursuant to this Agreement and then
held subject to the Escrow Agreement as at such date, and the Vendors shall have
no further personal liability to SSPI in this regard.

12.3 In circumstances where more than one Vendor is liable under Section 12.1 as
a result of a misrepresentation or breach of warranty contained in Section 4.2,
the liability of such Vendors shall be apportioned such that each Vendor who is
liable bears that portion of the entire liability, limited in the aggregate as
stated in Section 12.2, as is equal to the percentage of the SSPI Special
Warrants acquired by such Vendor pursuant to this Agreement in relation to the
total number of Special Warrants acquired by all the Vendors who are liable.

12.4 Subject to the maximum limit on liability in Section 12.2, each Vendor can
satisfy any liability referred to in Section 12.2 and Section 12.3 herein by
either paying the amount thereof to SSPI or surrendering or causing to be
surrendered to SSPI such of the Vendor's SSPI Special Warrants or SSPI Shares or
the rights thereto then held subject to the Escrow Agreement as at the date of
receipt of a claim for indemnity as have a market value equal to the amount of
the liability.

12.5 In circumstances where a Vendor is liable under Section 12.1 in respect of
a misrepresentation or breach of warranty as it relates to a representation or
warranty contained in Section 4.1, SSPI agrees that it shall first exhaust
recourse against the SSPI Special Warrants or SSPI Shares of such Vendor, as the
case may be, then held subject to the Escrow Agreement, to satisfy such
liability in which case the provisions of Section 12.4 apply mutatis mutandis,
and SSPI will only further seek recourse against such Vendor generally in
circumstances where the market value of such SSPI Special Warrants or SSPI
Shares, as the case may be, is not sufficient to satisfy such liability under
Section 12.1.

12.6 For the purposes of Section 12.2 and Section 12.4 herein the "market value"
of the SSPI Special Warrants or SSPI shares or the rights thereto shall be
deemed to be equal to the weighted average of the closing prices at which SSPI's
common shares have traded on the Alberta Stock Exchange or, if such shares are
not then listed on the Alberta Stock Exchange, on such stock exchange or
electronic trading facility on which the shares then trade as may be selected by
the board of directors of SSPI, during the 20 most recent trading days ending on
the trading day immediately prior to the date of a claim for indemnity.

12.7 The provisions of Section 12 apply mutatis mutandis to Hefner with respect
to any misrepresentation or breach of warranty on the part of Hefner under this
Agreement.

            misrepresentation, breach of warranty or non-fulfilment of any
            covenant on the part of SSPI under this Agreement or from any
            misrepresentation in or omission from any certificate or other
            instrument furnished or to be furnished to the Vendors hereunder;
            and

      (b)   any and all actions, suits, proceedings, demands, assessments,
            judgments, costs and legal and other expenses incidental to any of
            the foregoing;

and if any action or claim shall be asserted against the Vendors in respect of
which indemnity may be sought hereunder, the Vendors shall notify SSPI in
writing and SSPI shall assume the defence thereof at its expense through legal
counsel acceptable to the Vendors. No party shall effect a settlement of such
action or claim without the written consent of the other party, such consent not
to be unreasonably withheld or delayed.

12.9 SSPI shall bear the costs relating to the test procedures in respect of the
El Segundo No. 1 well as detailed in Schedule "J". To the extent such costs
exceed the amounts set forth in Schedule "J", the Vendors, together with the
vendors under the Cimarrona Agreement and the GHK Agreement, shall reimburse
SSPI for the excess pursuant to Section 12.10 hereof.

12.10 If the costs relating to the test procedures in respect of El Segundo No.
1 well exceed the amounts set forth in schedule "J", GHK Company Columbia shall
submit invoices to the Manager (as defined in the Management Contract), SSPI,
and the Vendors in respect of such excess amounts within 90 days of the date
hereof. Once satisfied that such invoices accurately reflect actual costs
incurred in respect of the test procedures, the Vendors shall within 30 days
after such 90-day period pay to the Manager, and direct the Manager to pay to
SSPI, a portion of such costs equivalent to their pro rata share of the
aggregate number of warrants and preference shares in SSPI issued to the Vendors
under this Agreement and the vendors under Cimarrona Agreement and the GHK
Agreement.

12.11 The Vendors shall be entitled to a portion, equivalent to their pro rata
share of the aggregate number of warrants and preference shares in SSPI issued
to the Vendors under this Agreement and the vendors under the Cimarrona
Agreement and the GHK Agreement, of any revenues generated by the production or
sale of oil produced from the el Segundo No. 1 well prior to the Closing. The
Vendors shall be entitled to require from GHK Company Columbia an accounting of
any such revenues within 90 days of the date hereof and SSPI shall within 30
days after such 90-day period pay to the Vendors the portion of such proceeds
set forth in this Section 12.11.

            receipt for a Prospectus qualifying the exchange of the Warrants for
            Common Shares without condition or restriction on the resale of such

<PAGE>
                                                                  EXECUTION COPY
                                      - 4 -

      (b)   staff of any Commission exercises its discretion to refuse to issue
            a final receipt for a Prospectus qualifying the exchange of the
            Warrants for Common Shares without condition or restriction on the
            resale of such Common Shares,

then a Participant shall have the right, to be exercised in accordance with the
terms of this Agreement, to required the Company to use its best efforts to
qualify the Participant's Shares for resale to the public under a Prospectus for
which a final receipt has been received from the Commission in each province in
which the Company is, at the date of such Prospectus, a Reporting Issuer (a
"Required Qualification").

2.2 After receipt of a written request from a Participant requesting a Required
Qualification, the Company shall promptly notify all other Participants in
writing of the receipt of such request and each such Participant may elect (by
written notice sent to the Company within 10 Business Days after the date of
such holder's receipt of the Company's notice) to have its Participant Shares
included in the Required Qualification. Thereupon the Company shall, as
expeditiously as is possible, use its best efforts to file a preliminary
Prospectus and a final Prospectus and obtain receipts therefor under the
Securities Act of each province in which the Company is at the time a Reporting
Issuer qualifying all Participant Shares which the Company has been so requested
to qualify by Participants for sale, all to the extent required to permit the
disposition of the Participant Shares so qualified.

2.3 The rights of Participants under sections 2.1 and 2.2 are subject to the
limitations set forth in sections 8.1 and 8.2.

2.4 The Company shall have the opportunity to include in any Required
Qualification common shares of the Company, provided, however, that any such
shares shall not be included in such Required Qualification unless the Company
agrees to use the managing underwriter selected pursuant to Section 9.1 for the
distribution of the Participant Shares to be offered in such Required
Qualification.

      If the managing underwriter of a Required Qualification shall advise the
Company in writing that, in its opinion, the distribution of Participant Shares
and other shares requested to be included in such Required Qualification would
materially and adversely affect the distribution of such securities at a price
deemed acceptable by the holders of a majority of the Participant Shares to be
included in such Required Qualification, then the Company will include in such
qualification, to the extent of the number of equity securities which the
Company is advised can be sold in such offering:

            FIRST, Participant Shares, allocated pro rata on the basis of the
            number of Participant Shares requested to be registered by
            Participants, and

            SECOND, other shares allocated in such manner as the Company shall
            determine.
<PAGE>
                                                                  EXECUTION COPY
                                      - 5 -

      Except as otherwise provided in Section 5.1 all expenses of such
qualification shall be borne by the Company.

2.5   A Required Qualification shall not be deemed to have been effected

      (a)   unless a final Prospectus with respect thereto has been receipted
            and the Common Shares have not become subject to a cease-trade
            order, injunction or other requirement of the Commission or other
            governmental agency or court for any reason for the shorter of such
            period as is necessary to distribute the Participant Shares of the
            holders requiring such Required Qualification and qualified
            thereunder and 90 days, provided, however, that a Required
            Qualification which does not receive a final receipt after the
            Company has filed a Prospectus with respect thereto solely by reason
            of the refusal to proceed of the holders of Participant Shares shall
            be deemed to have been effected by the Company, or

      (b)   if the conditions to closing specified in the purchase agreement or
            underwriting agreement entered into in connection with such
            qualification are not satisfied, other than by reason of some act or
            omission by the holders of Participant Shares requiring such
            Required Qualification.

SECTION 3 -- PIGGYBACK RIGHTS

3.1 If, so long as the Shareholders Voting Support Agreement is in effect, the
Company at any time proposes to file on its behalf (it shall be deemed a Company
proposal hereunder to file a Prospectus if the shareholders of the Company shall
agree at any time to make such a filing) or on behalf of any of its holders of
Common Shares other than the Participants (the "demanding security holders") a
Prospectus under the Securities Act in order to qualify the sale to the public
of Common Shares (a "Public Offering") or the Company proposes to effect any
prospectus-exempt sale of any of its securities (a "Private Placement"), it will
give written notice to all Participants at least 30 days before the initial
filing with the Commission of such Prospectus or immediately upon determining to
effect a Private Placement, as the case may be, which notice shall set forth the
proposal for disposition of the securities proposed to be sold by the Company.
The notice shall offer to include in such Public Offering or Private Placement
such Participant Shares or Warrants as such Participants may request subject to
Section 3.2 hereof. Where the Company proposes to file on its behalf only (and
not on behalf of any demanding security holders) a prospectus to qualify a
Public Offering or proposes to effect a Private Placement and where the managing
underwriter of such proposed Public Offering or Private Placement shall advise
the Company in writing that, in its opinion, the inclusion of any Participant
Shares or Warrants in the Public Offering or Private Placement concurrently with
the securities being qualified or offered for sale by the Company would
materially and adversely affect the distribution of such securities by the
Company at a price deemed acceptable by the Company, then the Company shall not
be obliged to give written notice to

<PAGE>
                                                                  EXECUTION COPY
                                      - 6 -

the Participants pursuant to this Section 3.1 and shall not be obliged to
include in such Public Offering or Private Placement any Participant Shares or
Warrants.

3.2 Each Participant desiring to have its Participant Shares or Warrants
qualified or offered for sale under this Section 3 shall advise the Company in
writing within 30 days (if a Public Offering) or 15 days (if a Private
Placement) after the date of receipt of such offer from the Company, setting
forth the amount of Participant Shares or Warrants for which qualification or
offering for sale is requested. The Company shall thereupon include in such
Public Offering or Private Placement the Participant Shares or Warrants for
which qualification or offering for sale is so requested and shall use its best
efforts to effect the qualification or offering for sale under the Securities
Act of such Participant Shares or Warrants; provided, that no Participant Shares
or Warrants will be included in such qualification or offering for sale unless
such Participant agrees to use the managing underwriter selected by the Company,
and provided further that the Company, without liability to any Participant, may
terminate such Public Offering or Private Placement at any time. If the managing
underwriter of a proposed Public Offering or Private Placement shall advise the
Company in writing that, in its opinion, the distribution of the Participant
Shares or Warrants requested to be included in the Public Offering or Private
Placement concurrently with the securities being qualified or offered for sale
by the Company would materially and adversely affect the distribution of such
securities by the Company at a price deemed acceptable by the Company, then all
selling security holders (other than the Company, if it is effecting such
qualification for securities to be offered by it for its own account) shall
reduce the amount of securities each intended to distribute through such
offering on a pro rata basis in an aggregate amount recommended by the managing
underwriter. For greater certainty, the aggregate amount so recommended may be
equal to the entire amount of securities that such selling security holders
intended to so distribute. Except as otherwise provided in Section 5.1 all
expenses of such qualification shall be borne by the Company.

SECTION 4 -- QUALIFICATION PROCEDURES

4.1 If the Company is required by the provisions hereof to use its best efforts
to effect the qualification or offering for sale to the public of any of the
Participant Shares or Warrants, the Company will, as expeditiously as possible:

      (a)   prepare and file a preliminary Prospectus with respect to such
            Participant Shares and use its best efforts to cause the Commission
            to issue a receipt for a final Prospectus as required for the
            disposition of such Participant Shares by the holders thereof or
            prepare and complete such other offering document as may be
            necessary or advisable in order to effect a Private Placement of
            Participant Shares or Warrants, as the case may be;

<PAGE>
                                                                  EXECUTION COPY
                                      - 7 -

      (b)   prepare and file with the Commission such supplements or amendments
            to such Prospectus as may be necessary to keep such Prospectus
            accurate in all material respects and to comply with the provisions
            of the Securities Act with respect to the sale of all Participant
            Shares covered by such Prospectus until such time as all such
            Participant Shares have been disposed of in a public offering;

      (c)   furnish to such selling Participants such number of copies of a
            Prospectus, including a preliminary Prospectus, in conformity with
            the requirements of the Securities Act, and such other documents

            Participants may reasonably request;

      (d)   use its best efforts to qualify the Participant Shares covered by
            such Prospectus under such other securities laws of such
            jurisdictions within Canada where the Company is a Reporting Issuer
            on the date of the request as each Participant shall reasonably
            request and do such other reasonable acts and things as may be
            required of it to enable such Participant to consummate the
            disposition in such jurisdiction of the Participant Shares covered
            by such Prospectus;

      (e)   furnish, at the request of any Participant requesting qualification
            or offering for sale to the public of Participant Shares or
            Warrants, on the date that such Participant Shares or Warrants are
            delivered to the underwriters for sale pursuant to such
            qualification or offering, (i) an opinion, dated such date, of the
            independent counsel representing the Company for the purposes of
            such qualification or offering, addressed to the underwriters,
            covering such legal matters in respect of which such opinion is
            being given as such Participants may reasonably request; and (ii) a
            letter dated such date, from the independent chartered accountants
            of the Company, addressed to the underwriters, stating that they are
            independent chartered accountants and that, in the opinion of such
            accountants, the financial statements and other financial data of
            the Company included in the Prospectus or other offering document,
            or any amendment or supplement thereto, comply as to form in all
            material respects with the applicable accounting requirements of the
            Securities Act. Such letter from the independent chartered
            accountants shall additionally cover such other financial matters
            (including information as to the period ending not more than five
            Business Days prior to the date of such letter) with respect to the
            qualification in respect of which such letter is being given as such
            Participants may reasonably request; and

      (f)   enter into customary agreements (including an underwriting agreement
            in customary form) and take such other actions as are reasonably
            required in order to expedite or facilitate the disposition of such
            Participant Shares or Warrants.

      It shall be a condition precedent to the obligation of the Company to take
any action pursuant to this Agreement in respect of the Participant Shares or
Warrants which are to be

<PAGE>
                                                                  EXECUTION COPY
                                      - 8 -

qualified or offered at the request of any Participant that such Participant
shall furnish to the Company such information regarding the Participant Shares
or Warrants held by such Participant as the Company shall reasonably request and
as shall be required in connection with the action taken by the Company.

SECTION 5 -- EXPENSES

5.1 All expenses incurred in complying with this Agreement, including, without
limitation, all filing fees, printing expenses, fees and disbursements of
counsel for the Company, the reasonable fees and expenses of one counsel for the

Participant Shares being qualified), expenses of any special audits incident to
or required by any such qualification and expenses of complying with the
securities laws of any jurisdictions pursuant to Section 4.1(d), shall be paid
by the Company, except to the extent that any expenses are required by
applicable law to be paid by the Participants, and to the extent that the
Company shall not be liable for any fees, discounts or commissions to any
underwriter or any fees or disbursements of counsel for any underwriter in
respect of the Participant Shares or Warrants sold by such Participant.

SECTION 6 -- INDEMNIFICATION AND CONTRIBUTION

6.1 In the event of any qualification of any of the Participant Shares or
Warrants under the Securities Act pursuant to this Agreement, the Company shall
indemnify and hold harmless each Participant, such Participant's directors and
officers, if any, and each other Person (including each underwriter) who
participated in the offering of such Participant Shares or Warrants and each
other Person, if any, who controls such Participant or such other participating
Person within the meaning of the Securities Act, against any losses, claims,
damages or liabilities, joint or several, to which such Participant or any such
director or officer or participating Person or controlling Person may become
subject under the Securities Act or any other statute or at common law, insofar
as such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon (i) any alleged untrue statement of any material
fact contained in any Prospectus or other offering document, or any amendment
thereto, under which such Participant Shares or Warrants were qualified, or (ii)
any alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and shall
reimburse such Participant or such director, officer or participating Person for
any legal or any other expenses reasonably incurred by such Participant or such
director, officer or participating Person in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the Company shall not be liable in any such case to the extent that any
such loss, claim, damage or liability arises out of or is based upon any untrue
statement or omission made in such Prospectus or other offering memorandum or
amendment thereto in reliance upon and in conformity with written information
furnished to the Company by such Participant specifically for use therein or (in
the case of any qualification pursuant to Section 2) so furnished for such
purposes by any underwriter. Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of such Participant
or such
<PAGE>
                                                                  EXECUTION COPY
                                      - 9 -

director, officer or participating Person or controlling Person, and shall
survive the transfer of such Participant Shares or Warrants by such Participant.

6.2 Each Participant shall indemnify and hold harmless the Company, its
directors and officers and each other Person, if any, who controls the Company
within the meaning of the Securities Act against any losses, claims, damages or
liabilities, joint or several, to which the Company or any such director or
officer or any such Person may become subject under the Securities Act or any
other statute or at common law, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon
information in writing provided to the Company by such Participant contained in
any Prospectus or other offering document under which Participant Shares or
Warrants were qualified under the Securities Act at the request of such
Participant, or any amendment thereto and which information constituted an
untrue statement of a material fact or omitted to state a material fact required
to be stated therein necessary to make the statements therein not misleading;
provided, however, the aggregate amount which may be recovered by the Company,
its directors and officers and each other Person who controls the Company within
the meaning of the Securities Act pursuant to the indemnification provided for
in this Section 6 shall be limited to the total price at which the Participant
Shares or Warrants sold by such Participant were offered to the public.

6.3 If the indemnification provided for in this Agreement from the indemnifying
party is unavailable to an indemnified party hereunder in respect of any losses,
claims, damages, liabilities or expenses referred to therein, then the
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or expenses in such proportion as
is appropriate to reflect the relative fault of the indemnifying party and
indemnified parties in connection with the actions which resulted in such
losses, claims, damages, liabilities or expenses as well as any other relevant
equitable considerations. The relative fault of such indemnifying party and
indemnified parties shall be determined by reference to, among other things,
whether any action in question, including any untrue or alleged untrue statement
of a material fact or omission or alleged omission to state a material fact, has
been made by, or relates to information supplied by, such indemnifying party or
indemnified parties, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action. The amount paid
or payable by a party as a result of the losses, claims, damages, liabilities
and expenses referred to above shall be deemed to include any legal or other
fees or expenses reasonably incurred by such party in connection with any
investigation or proceeding.

      The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 6.3 were determined by pro rata allocation
or by any other method of allocation which does not take account of the
equitable considerations referred to in the immediately preceding paragraph. No
Person guilty of fraudulent misrepresentation shall be entitled to contribution
from any Person who was not guilty of such fraudulent misrepresentation.

SECTION 7 -- LISTING ON SECURITIES EXCHANGE

which the Common Shares are listed for the necessary additional listing of all
Common Shares issued thereby.

SECTION 8 -- CERTAIN LIMITATIONS ON QUALIFICATION RIGHTS

8.1 Notwithstanding the other provisions of this Agreement the Company shall not
be obligated to qualify for sale to the public by way of a Public Offering the
Participant Shares or Warrants of any Participant if in the opinion of counsel
to the Company reasonably satisfactory to such Participant and its counsel (or,
if the Participant has engaged an investment banking firm, to such investment
banking firm and its counsel), the sale or other disposition of such
Participant's Participant Shares or Warrants, in the manner proposed by such
Participant (or by such investment banking firm), may be effected without
qualifying such Participant Shares or Warrants under the Securities Act.

8.2 The rights of a Participant under sections 2.1 and 2.2 may only be exercised
three times provided, however, that if the Common Shares become listed and
posted for trading on The Toronto Stock Exchange or the Montreal Exchange, such
rights may only be exercised two times.

SECTION 9  -- SELECTION OF MANAGING UNDERWRITERS

9.1 The managing underwriter or underwriters for any offering of Participant
Shares or Warrants to be qualified pursuant to Section 2 shall be selected by
the holders of a majority of the Participant Shares or Warrants initiating such
Required Qualification and shall be reasonably acceptable to the Company. The
Company shall select the managing underwriter or underwriters for any offering
of securities in which Participant Shares or Warrants are included pursuant to
Section 3.2 hereof.

SECTION 10 -- SUPPLYING INFORMATION

10.1 The Company shall cooperate with each Participant in supplying such
information as may be reasonably necessary for such Participant to complete and
file any information reporting forms presently or hereafter required by the
Commission as a condition to the availability of an exemption from the
Securities Act for the sale of Participant Shares or Warrants; provided,
however, that the Company shall not be required by the terms hereof to become a
Reporting Issuer in any province in which it is not a Reporting Issuer at the
time of the sale.

SECTION 3 - EXERCISE OF VOTING POWER

3.1 EXERCISE OF VOTING POWER. Until termination of this Agreement under section

each of the Shareholders shall vote or cause to be voted all voting shares of

4.1 ORDINARY COURSE SALES. Hefner and Kerr are free to sell any or all Warrants
or common shares of the Company acquired on conversion of the Warrants, provided
that, subject to section 4.2, in the event of a proposed sale by Hefner or Kerr
of any Block, Yorkton Securities or such other investment dealer as may be
designated by the Board from time to time will be afforded the first opportunity
to sell such Block. If Yorkton Securities (or any other such designated dealer)
cannot sell the Block on a timely basis and at a price acceptable to Hefner or
Kerr, as the case may be, Hefner or Kerr will be entitled, acting in good faith,
to conclude a sale to a third party provided that such sale is not to a person,
or one or more of a group of persons acting in concert, who is acquiring the
Block in connection with a takeover bid other than in the circumstances
described in sub-clause 4.2(b). If Hefner or Kerr does not provide Yorkton
Securities (or any other such designated dealer) with the first opportunity to
sell the Block, he will, as a condition of such sale to a third party, require
the third party purchaser to agree to be bound by the terms of this Agreement.

subject to the escrow agreement dated as of the date of this Agreement between,
among others, Hefner, Kerr, the Company and Montreal Trust Company of Canada,
shall not be subject to the selling restrictions contained in section 4.1.

      (b) If a take-over bid or other offer is made generally to shareholders of
the Company by an arms-length third party for all or a portion of the common
shares of the Company, Hefner and Kerr will be free to tender to such bid or
offer any common shares owned by them and shall not be required to comply with
the selling restrictions contained in section 4.1.

            month period which is in excess of 25% of the outstanding share
            capital of the Company at the beginning of such period and does not
            obtain approval therefor from the shareholders of the Company; and

SECTION 6 - CLOSING CERTIFICATE

interpreted in such manner as to be effective and valid under applicable law,

under applicable law, such provision will be ineffective only to the extent of
such prohibition or invalidity, without invalidating the remainder of this
Agreement.

7.5 COUNTERPARTS. This Agreement may be executed simultaneously in two or more
counterparts, each of which shall constitute an original, but all of which taken
together shall constitute one and the same Agreement.

The parties have executed this Agreement.

            NAME                                OFFICE

            Robert A. Hefner III                President and Director
            Larry A. Ray                        Executive Vice President
                                                and Director
            Robert S. May                       Vice President (Finance)
                                                and Assistant Treasurer
            Jane Ryder                          Assistant Secretary
            Russ D. Cunningham                  Vice President (Geology)

It should be noted that Robert A. Hefner III (i) is to become a director of
Seven Seas, (ii) was the sole stockholder of GHK Colombia prior to the date
first above written and (iii) is the principal owner of the Manager. It is also
understood that Al Whitehead is Chairman of the Board, and that Timothy T.
Stephens and David F. DeCort also serve as directors of GHK Colombia.

            C. The parties intend, subject to this Agreement, that the Service
Group shall act on behalf of GHK Colombia in performing its duties and
responsibilities as a member of the Association and as operator under the JOA,
subject to the direction of the directors of GHK Colombia.
<PAGE>
            ACCORDINGLY, premises considered and for the purpose of providing a
basis among which the Manager will provide certain administrative services and
make available certain of its employees to GHK Colombia, the parties have
entered into this Agreement.

            1. MANAGER SERVICES. The Manager will make available, on an as
needed basis, the Service Group, together with its offices and facilities in
Oklahoma City, Oklahoma, and Denver, Colorado, U.S.A. to provide such services
and administrative support as may be required to enable GHK Colombia to perform
its duties and obligations as the operator of the Association and under the JOA.
The services shall be performed, in part, by causing the Service Group to serve
as directors and officers of GHK Colombia as hereinafter provided.

            2. SERVICE GROUP. Members of the Service Group shall serve as
officers and directors of GHK Colombia without compensation or benefits and the
Manager shall be solely responsible for matters relating to their compensation
and for other associated issues relating to employment including but not limited
to payroll taxes, income taxes, unemployment and workman's compensation and
health, accident and other insurances. Subject to the direction of the Board of
Directors of GHK Colombia, the Service Group shall have such authority to act on
behalf of GHK Colombia as are usual and customary for the offices and positions
that they hold; provided, however, no person shall be hired as an employee of
GHK Colombia without specific authorization from the Board of Directors. The
Manager will cause the Service Group to perform their duties as officers and
managers of GHK Colombia in such a way as to enable GHK Colombia to perform its
duties as operator and conduct operations under the JOA and the Association. The
Manager shall cause the Service Group to devote such part of their time as is
reasonably needed to fulfill these duties and manage GHK Colombia and its
business in such a way as to be, at all times during the term of this Agreement,
in compliance with its duties and obligations as a member and operator of the
Association and as operator under the JOA. It is understood that the performance
of such duties will not require the full time services of any member of the
Service Group and nothing in this Agreement shall be construed to prohibit any
member of the Service Group from performing services for the Manager in
connection with its other business activities or to engage in any other activity
that they see fit, subject only to the obligations provided under this
Agreement.

            3. SEVEN SEAS FINANCIAL SUPPORT. Seven Seas shall, as the sole
shareholder of GHK Colombia, elect Messrs. Hefner and Ray as directors of GHK
Colombia and shall cause the GHK Colombia directors to elect members of the
Service Group to the offices herein agreed upon. Seven Seas shall also provide
GHK Colombia capital funds sufficient for it to pay all obligations incurred by
it in connection with the performance of its duties under the Association, the
JOA and hereunder.

                                     -2-
<PAGE>
            4. MANAGER COMPENSATION. As compensation for services, GHK Colombia
will pay the Manager a monthly sum equal to 100% of the overhead charges
authorized under the JOA, plus $15,000. In addition, GHK Colombia will reimburse
the Manager and members of the Service Group for all direct expenses and
third-party costs incurred and paid by them in connection with the performance
of their duties hereunder or as officers and managers of GHK Colombia. Except as
authorized by the directors of GHK Colombia, neither the Manager nor any member
of the Service Group shall be authorized to incur costs and expenses not
authorized under the JOA. There shall be no duplication of reimbursed direct
expenses and third party costs and JOA overhead charges. GHK Colombia will not
be liable to the Manager for the termination by the Manager of any of the
Manager's employees, including those performing services for the benefit of GHK
Colombia hereunder. Seven Seas hereby guarantees the obligations of GHK Colombia
under this paragraph.

            5. INDEMNIFICATION. Neither the Manager nor any member of the
Service Group shall be liable or responsible for damages to GHK Colombia or
Seven Seas for any acts taken or performed or for any omission to act, if such
conduct does not constitute willful misconduct or gross negligence. In any
threatened, pending or completed action, suit or investigation in which the
Manager or any member of the Service Group was or is a party by virtue of its or
their activities under this Agreement or in connection with any member of the
Service Group serving as an officer, employee, director, agent or manager of GHK
Colombia, then GHK Colombia and Seven Seas, jointly and severally, shall
indemnify the Manager, its members, officers, employees and agents against all
judgments, settlements, penalties, fines or expenses, including attorneys' fees
incurred by the Manager or any member of the Service Group in connection
therewith, so long as the Manager's, or the member of the Service Group's,
action or failure to act does not constitute willful misconduct or gross
negligence.

            6. TERM. This Agreement shall continue in effect until the earlier
to occur of (i) the drilling and completion of both the second year well under
the Rio Seco Association Contract and the fourth year well under the Dindal
Association Contract or (ii) such time as "commerciality" is established under
either the Dindal or Rio Seco Association Contracts; provided, however, GHK
Colombia, Seven Seas, or Manager may terminate this Agreement at any time upon
180 days' prior written notice. Upon termination of this Agreement, the Manager
shall cause the members of the Service Group to tender their resignations as
officers and directors of GHK Colombia. Such resignations shall release the
Company from further obligations relating to compensation and other employee
benefits.

            7. GOVERNING LAW. This Agreement shall be governed by and construed
in accordance with the laws of the State of Oklahoma.

                                     -3-
<PAGE>
            8. NO ASSIGNMENT. No party may assign its rights or delegate its
duties under this Agreement without the prior written consent of the other
parties.

            9. COUNTERPARTS. This Agreement may be executed in any number of
identical counterparts, each of which shall be considered an original for all
purposes but all of which shall constitute one and the same agreement.

            EXECUTED as of the day and year first above written.

                                             (hereinafter called the
                                             "Issuer")

WHEREAS the Vendors or predecessors in title of one or more of them and the
Issuer (among others) entered into an agreement dated as of the 26th day of
July, 1996, whereby the Vendors or such predecessors agreed to sell or otherwise
transfer certain working interests in the Dindal and Rio Seco association
contracts located in Colombia (the "Property") to a wholly-owned subsidiary of
the Issuer, the consideration for such property being at least in part the
issuance of securities by the Issuer or the transfer of securities of the Issuer
to the Vendors or such predecessors, the number of securities subject to this
agreement (the "escrowed securities") and the names of the Vendors presently
owning or to receive such securities, being respectively and more particularly
described in Schedule "A" attached to and forming part of this agreement;

AND WHEREAS in furtherance of complying with the requirements of the SECURITIES
ACT, the Vendors are desirous of depositing in escrow certain securities in the
Issuer owned or to be received by them;
<PAGE>
                                      2

AND WHEREAS the Trustee has agreed to undertake and perform its duties according
to the terms and conditions hereof;

NOW THEREFORE this agreement witnesseth that in consideration of the aforesaid
agreements and other good and valuable consideration (the receipt and
sufficiency of which parties do hereby respectively acknowledge each to the
other), the Vendors jointly and severally covenant and agree with the Issuer and
with the Trustee and the Issuer and the Trustee covenant and agree each with the
other and with the Vendors jointly and severally as follows:

(1) Each of the Vendors hereby places and deposits in escrow those of the
Vendor's securities of the Issuer which are represented by the certificates
described or referred to in Schedule "A" hereto, with the Trustee and hereby
undertakes and agrees forthwith to deliver those certificates (including any
replacement securities or certificates if and when such are issued or allotted)
to the Trustee for deposit in escrow.

(2) The parties hereby agree that the securities and the beneficial ownership of
or any interest in them and the certificates representing them (including any
replacement securities or certificates) shall not be sold, assigned,
hypothecated, alienated, released from escrow, transferred within escrow or
otherwise in any manner dealt with, except in accordance with the terms of this
agreement or any written consent, order or direction in writing of the Ontario
Securities Commission (hereinafter referred to as the "Commission") or except as
may be required by reason of the death or bankruptcy of any Vendor, in which
cases the Trustee shall hold the said certificates, subject to this agreement,
for whatever person, firm or corporation shall be legally entitled to be or
become the registered owner thereof.

(3) The Vendors hereby direct the Trustee to retain their respective securities
and the certificates (including any replacement securities or certificates)
representing the same and not to do or cause anything to be done to release the
same from escrow or to allow any transfer, hypothecation or alienation thereof
except in accordance with the terms of this agreement or any written consent,
order or direction of the Commission. The Trustee hereby accepts the
responsibilities placed on it hereby and agrees to perform the same in
accordance with the terms hereof and any written consent, orders or directions
of the Commission. Nothing in this agreement shall prevent the Vendors from
exchanging the escrowed securities (which, initially, shall be special warrants
or convertible securities of the Issuer) in accordance with their terms for
common shares of the Issuer and the Trustee shall take such steps and perform
such acts as may be
<PAGE>
                                      3

necessary in order to effect any such exchange upon receipt of a written
direction from the Vendor or the Vendor's representative in respect of its
escrowed securities provided that the Issuer's common shares delivered to the
Trustee in exchange for the escrowed securities shall be held by the Trustee in
accordance with the terms of this agreement as if they were the escrowed
securities.

(4) If during the period in which any of the said securities are retained in
escrow pursuant hereto, any dividend is received by the Trustee in respect of
the escrowed securities, any such dividend shall be forthwith paid or
transferred to the respective registered owner entitled thereto.

(5) All voting rights attached to the escrowed securities shall at all times be
exercised by the respective registered owners thereof.

(6) The Vendors and the Issuer hereby jointly and severally agree to and do
hereby release and indemnify and save harmless the Trustee from and against all
claims, suits, demands, costs, damages and expenses which may be occasioned by
reason of the Trustee's compliance in good faith with the terms hereof.

(7) The Issuer hereby acknowledges the terms and conditions of this agreement
and agrees to take all reasonable steps to facilitate its performance and to pay
the Trustee's proper charges for its services as trustee of this escrow.

(8) The written consent, order or direction of the Commission as to a release
from escrow of all or part of the said securities, shall terminate this
agreement only in respect to those securities so released.

(9) Subject to any other release consented to by the Commission, the escrowed
securities shall be released from the terms of this agreement on the earlier of:

            a.    on each of the first three anniversaries of the date of the
                  initial issuance of the escrowed securities: one third of the
                  escrowed securities so that after the third anniversary of
                  such date all of the escrowed securities shall be released
                  from the terms of this agreement; and

            b.    such date, from time to time, as a Vendor or the Issuer
                  provides staff of the Commission with technical reports
                  acceptable to the Director that establish a determinate value
                  for the Property (as at April 25, 1996) of U.S. $118,908,000
                  or more;
<PAGE>
                                      4

                  provided that proportionate releases from escrow will be
                  permitted based on interim technical reports that establish a
                  determinate value of less than U.S. $118,908,000.

(10) If the Trustee should wish to resign, it shall give at least six months
notice to the Issuer, who may, with the written consent of the Commission, by
writing appoint another Trustee in its place and such appointment shall be
binding on the Vendors and the new Trustee shall assume and be bound by the
obligations of the Trustee hereunder.

(11) This agreement may be executed in several parts in the same form and such
parts as so executed shall together form one original agreement, and such parts
if more than one shall be read together and construed as if all the signing
parties hereto had executed one copy of this agreement.

(12) Wherever the singular or masculine are used throughout this agreement, the
same shall be construed as being the plural or feminine or neuter where the
context so requires.

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

                               ESCROW AGREEMENT

THIS Agreement made the 21st day of January, 1997

BETWEEN:

            ALBERT E. WHITEHEAD, 9 East 4th Street, Suite 305, Tulsa,
            Oklahoma, 74103 - 5109

            (herein called the "Security Holder")

                                                             OF THE FIRST PART

AND:

            MONTREAL TRUST COMPANY, of Suite 600, 530 - 8th Avenue S.W.,

AND:

            SEVEN SEAS PETROLEUM INC., of Suite 960, Three Post Oak

            U.S.A.

                                                             OF THE THIRD PART

WHEREAS:

A.          The Security Holder presently owns securities of the Issuer;

B.          In furtherance of complying with the requirements of the Toronto
Stock Exchange ( the "Exchange" ), the security holder is desirous of depositing
in escrow certain securities of the Issuer owned or to be received by him;

C.          The Trustee has agreed to undertake and perform its duties according
to the terms and conditions hereof;
<PAGE>
                                   - 2 -

NOW THEREFORE this Agreement witnesseth that in consideration of the aforesaid
agreements, and of the sum of one dollar ($1.00) now paid by the parties hereto,
each to the other (receipt of which sum the parties do hereby respectively
acknowledge each to the other) the Security Holder covenants and agrees with the
Issuer and with the Trustee and the Issuer and the Trustee covenant and agree
each with the other and with the Security Holder as follows:

1. The Security Holder hereby places and deposits in escrow those of his
securities of the Issuer referred to in Schedule "A" hereto with the Trustee and
hereby undertakes and agrees forthwith to deliver those certificates (including
any replacement securities or certificates if and when such are issued or
allotted) to the Trustee for deposit in escrow.

2.          The securities shall, subject to the provisions of paragraph 3
hereof, be released from escrow as follows:

            1/3 on June 29, 1996; 

            1/3 on June 29, 1997; and

            1/3 on June 29, 1998.

3           The parties hereby agree that the securities and the beneficial
ownership of or any interest in them and the certificates representing them
(including any replacement certificates) shall not be sold, assigned,
hypothecated, alienated, released from escrow, transferred within escrow, or
otherwise in any manner dealt with other than as provided for in paragraph 2,
without the express consent, order or direction in writing of the Exchange being
first had and obtained or except as may be required by reason of the death or
bankruptcy of the Security Holder, in which cases the Trustee shall hold the
said certificates subject to this Agreement, for whatever person, firm or
corporation shall be legally entitled to be or become the registered owner
thereof.

4           The Security Holder hereby directs the Trustee to retain his
securities and the certificates (including any replacement securities or
certificates) representing the same and not to do or cause anything to be done
to release the same from escrow or to allow any transfer, hypothecation or
alienation thereof other than as provided for in paragraph 2 except with and as
directed by the written consent, order or direction of the Exchange. The Trustee
hereby accepts the responsibilities placed on it hereby and agrees to perform
the same in accordance with the terms hereof and the written consents, orders or
directions of the Exchange.

5           If during the period in which any of the said securities are
retained in escrow pursuant hereto, any dividend is received by the Trustee in
respect of the escrowed securities, any such dividend shall be forthwith paid or
transferred to the Security Holder entitled thereto.

6           All voting rights attached to the escrowed securities shall at all
times be exercised by the respective registered owners thereof.

7           The parties hereby agree that the Exchange may, in certain
circumstances, including but not limited to the suspension from trading or
delisting of the Issuer by the Exchange, require that all or any of the
securities then in escrow be tendered to the Issuer by
<PAGE>
                                   - 3 -

way of gift or for cancellation. Any such securities shall remain in escrow
subject to the terms and conditions of this Agreement until the securities are
fully and effectually cancelled or otherwise transferred for the benefit of the
Issuer. Where the securities cannot be cancelled, they shall be held for benefit
of the Issuer by the Trustee and remain in escrow subject to the terms and
conditions of this Agreement but they shall not be voted and any dividends shall
be donated back for the benefit of the Issuer.

8           The Issuer and Security Holder hereby agree to and do hereby release
and indemnify and save harmless the Trustee from and against all claims, suits,
demands, costs, damages and expenses which may be occasioned by reason of the
Trustee's compliance in good faith with the terms hereof.

9           The Issuer hereby acknowledges the terms and conditions of this
Agreement and agrees to take all reasonable steps to facilitate its performance
and to pay the trustee's proper charges for its services as trustee of this
escrow.

10          If the Trustee should wish to resign, it shall give at least three
months notice to the Issuer, which may, with the written consent of the
Exchange, by writing appoint another Trustee in its place and such appointment
shall be binding on the Security Holder and the new Trustee shall assume and be
bound by the obligations of the Trustee hereunder.

11          The release from escrow of all or part of the said securities shall
terminate this Agreement only in respect to those securities so released. For
greater certainty, this clause does not apply to securities transferred within
escrow.

12.         If the Issuer is delisted by the Exchange, thereafter any consent,
order or direction of the Exchange herein required will, instead, require the
consent, order or direction of the Ontario Securities Commission and the
Commission may require that escrowed securities be tendered to the Issuer by way
of gift or for cancellation pursuant to paragraph 6 hereof.

13.         This Agreement may be executed in several parts in the same form and
such parts as so executed shall together form one original agreement, and such
parts if more than one shall be read together and construed as if all the
signing parties hereto had executed one copy of this Agreement.

14.         Wherever the singular or masculine are used throughout this
Agreement, the same shall be construed as being the plural or feminine or neuter
where the context so requires.

parties hereto, their and each of their heirs, executors, administrators,
successors and assigns.

                            SEVEN SEAS PETROLEUM INC.

                         AMENDED 1996 STOCK OPTION PLAN

1.          PURPOSE

            The purpose of the Amended 1996 Stock Option Plan (this "Plan) is to
provide a means whereby selected employees, senior officers and directors of
Seven Seas Petroleum Inc. (the "Company"), or of any affiliate thereof, may be
granted incentive stock options to purchase Common Shares (as defined in Section
3) of the Company, in order to attract and retain the services or advice of such
employees, senior officers and directors, and to provide added incentive to such
persons by encouraging share ownership in the Company.

2.          ADMINISTRATION

            This Plan shall be administered by the Board of Directors of the
Company (the "Board") or, in the event the Board shall appoint and/or authorize
a committee to administer this Plan, by such committee. The administrator of
this Plan shall hereinafter be referred to as the "Plan Administrator".

            In the event a member of the Board (or the committee) may be
eligible, subject to the restrictions set forth in Section 4, to participate in
or receive or hold options under this Plan, no member of the Board or the
committee shall vote with respect to the granting of an option hereunder to
himself or herself, as the case may be.

            The members of any committee serving as Plan Administrator shall be
appointed by the Board for such term as the Board may determine. The Board may
from time to time remove members from, or add members to, the committee.
Vacancies on the committee, however caused, may be filled by the Board.

2.1         PROCEDURES

            The Board shall designate one of the members of the Plan
Administrator as chairman. The Plan Administrator may hold meetings at such
times and places as it shall determine. The acts of a majority of the members of
the Plan Administrator present at meetings at which a quorum exists, or acts
reduced to or approved in writing by all Plan Administrator members, shall be
valid acts of the Plan Administrator.

2.2         RESPONSIBILITIES

            Except for the terms and conditions explicitly set forth in this
Plan, the Plan Administrator shall have the authority, in its discretion, to
determine all matters relating to the options to be granted under this Plan,
including selection of the individuals to be granted options, the number of
shares to be subject to each option, the exercise price, and all other terms
<PAGE>
                                      - 2 -

and conditions of the options. Grants under this Plan need not be identical in
any respect, even when made simultaneously. The interpretation and construction
by the Plan Administrator of any terms or provisions of this Plan or any option
issued hereunder, or of any rule or regulation promulgated in connection
herewith, shall be conclusive and binding on all interested parties.

3.          SHARES SUBJECT TO THIS PLAN

            The shares subject to this Plan shall be the Company's common
shares, without par value (the "Common Shares"), presently authorized but
unissued or subsequently acquired by the Company. Subject to adjustment as
provided in Section 6, the aggregate amount of Common Shares to be delivered
upon the exercise of all options granted under this Plan shall not exceed
3,000,000 shares as such Common Shares were constituted on the effective date of
this Plan. If any option granted under this Plan shall expire or be cancelled or
terminated for any reason without having been exercised in full, the unpurchased
shares subject thereto shall thereupon again be available for purposes of this
Plan.

4.          ELIGIBILITY

            An incentive stock option may be granted only to any individual who,
at the time the option is granted, is an employee, senior officer or director of
the Company or an affiliate of the Company as that term is defined in the
BUSINESS CORPORATIONS ACT (Yukon Territory) (an "Affiliate"), a trustee on
behalf of such individual, or an entity, all of the voting securities of which
are beneficially owned by an employee or director. Any party to whom an option
is granted under this Plan shall be referred to hereinafter as an "Optionee".

5.          TERMS AND CONDITIONS OF OPTIONS

            Options granted under this Plan shall be evidenced by written
agreements which shall contain such terms, conditions, limitations and
restrictions as the Plan Administrator shall deem advisable and which are not
inconsistent with this Plan. Notwithstanding the foregoing, options shall
include or incorporate by reference the following terms and conditions:

5.1         NUMBER OF SHARES AND PRICE

            The maximum number of shares that may be reserved pursuant to the
exercise of each option and the price per share at which such option is
exercisable (the "Exercise Price") shall be as established by the Plan
Administrator, provided that the number of shares that may be reserved pursuant
to the exercise of options and granted to any person shall not exceed 5% of the
issued and outstanding share capital of the Company, and further provided that
the Plan Administrator shall act in good faith to establish the exercise price
which shall be not less than the closing price of the Company's shares on the
Toronto Stock Exchange on the day immediately preceding the date of grant of
such options.
<PAGE>
                                      - 3 -

5.2         TERM AND MATURITY

            The term of each incentive stock option shall be as established by
the Plan Administrator and, if not so established, shall be 5 years from the
date it is granted but in no event shall it exceed 10 years.

            To ensure that the Company or Affiliate will achieve the purpose and
receive the benefits contemplated in this Plan, the Plan Administrator may, in
respect of any options granted to any Optionee hereunder, establish a schedule
for the exercise of such option (a "Vesting Schedule").

5.3         EXERCISE

            Subject to any Vesting Schedule each option may be exercised in
whole or in part at any time and from time to time; provided, however, that no
fewer than 100 shares (or the remaining shares then purchasable under the
option, if less than 100 shares) may be purchased upon any exercise of option
rights hereunder and that only whole shares will be issued pursuant to the
exercise of any option. During an Optionee's lifetime, any options granted under
this Plan are personal to him or her and are exercisable solely by such
Optionee. Options shall be exercised by delivery to the Company of notice of the
number of shares with respect to which the option is exercised, together with
payment of the exercise price.

5.4         PAYMENT OF EXERCISE PRICE

            Payment of the option exercise price shall be made in full at the
time the notice of exercise of the option is delivered to the Company and shall
be in cash, bank certified or cashier's cheque, personal cheque (unless at the
time of exercise the Plan Administrator in a particular case determines not to
accept a personal cheque), or such other forms of payment as the Company may
accept, for the Common Shares being purchased.

            The Plan Administrator can determine at any time before exercise
that additional forms of payment will be permitted. To the extent permitted by
the Plan Administrator and applicable laws and regulations (including, but not
limited to, federal tax law, securities laws and regulations and provincial
company law), an option may be exercised by delivery of Common Shares of the
Company held by an Optionee having a fair market value equal to the exercise
price, such fair market value to be determined in good faith by the Plan
Administrator; provided, however, that payment in Common Shares held by an
Optionee shall not be made unless the Common Shares shall have been owned by the
Optionee for a period of at least six months.

5.5         WITHHOLDING TAX REQUIREMENT

            The Company or any Affiliate shall have the right to retain and
withhold from any payment of cash or Common Shares under this Plan the amount of
taxes required by any government to be withheld or otherwise deducted and paid
with respect to such payment. At its discretion, the Company may require an
Optionee receiving Common Shares to reimburse
<PAGE>
                                      - 4 -

the Company for any such taxes required to be withheld by the Company and
withhold any distribution in whole or in part until the Company is so
reimbursed. In lieu thereof, the Company shall have the right to withhold from
any other cash amounts due or to become due from the Company to the Optionee an
amount equal to such taxes. The Company may also retain and withhold or the
Optionee may elect, subject to approval by the Company at its sole discretion,
to have the Company retain and withhold a number of shares having a market value
not less than the amount of such taxes required to be withheld by the Company to
reimburse the Company for any such taxes and cancel (in whole or in part) any
such shares so withheld.

5.6         NON-TRANSFERABILITY OF OPTIONS

            Options granted under this Plan and the rights and privileges
conferred hereby may not be transferred, assigned, pledged or hypothecated in
any manner (whether by operation of law or otherwise) other than by will or by
the applicable laws of descent and distribution and shall not be subject to
execution, attachment or similar process. Any attempt to transfer, assign,
pledge, hypothecate or otherwise dispose of any option under this Plan or any
right or privilege conferred hereby, contrary to the provisions of this Plan, or
the sale or levy or any attachment or similar process upon the rights and
privileges conferred hereby shall be null and void. In the event of the death of
an Optionee the option may be exercised by the personal representative of the
Optionee's estate or by the person or persons to whom the Optionee's rights pass
by will or by the applicable laws of descent and distribution.

5.7         TERMINATION OF RELATIONSHIP

            If the Optionee's relationship with the Company or any Affiliate
ceases for any reason other than termination for cause, death or total
disability, and unless by its terms the option sooner terminates or expires,
then the Optionee may exercise, for a ninety day period that portion of the
Optionee's option which is exercisable at the time of such cessation, but the
Optionee's option shall terminate at the end of such period following such
cessation as to all shares for which it has not theretofore been exercised,
unless such provision is waived in the agreement evidencing the option or by
resolution adopted at any time by the Plan Administrator. If an Optionee's
relationship with the Company or any Affiliate changes (i.e., from employee to
nonemployee, such as a consultant), such change shall constitute a termination
of an Optionee's relationship with the Company or any Affiliate and the
Optionee's option shall terminate in accordance with this subsection 5.7. Upon
the expiration of the ninety day period following cessation of an Optionee's
relationship with the Company or any Affiliate, the Plan Administrator shall
have sole discretion in a particular circumstance to extend the exercise period
following such cessation beyond that specified above, subject to any extension
being pre-cleared by The Toronto Stock Exchange.

            If an Optionee is terminated for cause, any option granted hereunder
shall automatically terminate as of the first discovery by the Company of any
reason for termination for cause, and such Optionee shall thereupon have no
right to purchase any shares pursuant to such option. "Termination for cause"
shall mean dismissal for dishonesty, conviction or confession of a crime
punishable by law (except minor violation), fraud, misconduct or disclosure of
confidential information. If an Optionee's relationship with the Company or any
<PAGE>
                                      - 5 -

Affiliate is suspended pending an investigation of whether or not the Optionee
shall be terminated for cause, all the Optionee's rights under any option
granted hereunder likewise shall be suspended during the period of
investigation.

            If an Optionee's relationship with the Company or any Affiliate
ceases because of a total disability, no further vesting shall occur after the
cessation, the Optionee's option shall not terminate until the end of the
24-month period following such cessation (unless by its terms it sooner
terminates and expires). As used in this Plan, the term "total disability"
refers to a mental or physical impairment of the Optionee which is expected to
last for a continuous period of 12 months or more and which causes the Optionee
to be unable, in the opinion of the Company and two independent physicians, to
perform his or her duties for the Company and to be engaged in any substantial
gainful activity. Total disability shall be deemed to have occurred on the first
day after the Company and the two independent physicians have furnished their
opinion of total disability to the Plan Administrator.

            For purposes of this subsection 5.7 a transfer of relationship
between the Company and any Affiliate shall not be deemed to constitute a
cessation of relationship with the Company or any of its Affiliates. For
purposes of this subsection 5.7, with respect to incentive stock options,
employment shall be deemed to continue while the Optionee is on military leave,
sick leave or other bona fide leave of absence (as determined by the Plan
Administrator). The foregoing notwithstanding, employment shall not be deemed to
continue beyond the first 90 days of such leave, unless the Optionee's
reemployment rights are guaranteed by statute or by contract.

5.8         DEATH OF OPTIONEE

            If an Optionee dies while he or she has a relationship with the
Company or any Affiliate or within the ninety day period (or 24-month period in
the case of totally disabled Optionees) following cessation of such
relationship, any option held by such Optionee to the extent that the Optionee
would have been entitled to exercise such option, no further vesting occurring
after the date of death, may be exercised within one year after his or her death
by their personal representative of his or her estate or by the person or
persons to whom the Optionee's rights under the option shall pass by will or by
the applicable laws of descent and distribution but in any event, options may
not be exercised any later than the expiry date of such option.

5.9         NO STATUS AS SHAREHOLDER

            Neither the Optionee nor any party to whom the Optionee's rights and
privileges under the option may pass shall be, or have any of the rights or
privileges of, a shareholder of the Company with respect to any of the shares
issuable upon the exercise of any option granted under this Plan unless and
until such option has been exercised.
<PAGE>
                                      - 6 -

5.10        CONTINUATION OF EMPLOYMENT

            Nothing in this Plan or in any option granted pursuant to this Plan
shall confer upon any Optionee any right to continue in the employ of the
Company or of an Affiliate, or to interfere in any way with the right of the
Company or of any such Affiliate to terminate his or her employment or other
relationship with the Company at any time.

5.11        MODIFICATION AND AMENDMENT OF OPTION

            Subject to the terms and conditions and within the limitations of
this Plan, the Plan Administrator may modify or amend outstanding options
granted under this Plan, subject to the prior approval of The Toronto Stock
Exchange. The modification or amendment of an outstanding option shall not,
without the consent of the Optionee, impair or diminish any of his or her rights
or any of the obligations of the Company under such option. Except as otherwise
provided in this Plan, no outstanding option shall be terminated without the
consent of the Optionee.

6.          ADJUSTMENTS UPON CHANGES IN CAPITALIZATION

            The aggregate number and class of shares for which options may be
granted under this Plan, the number and class of shares covered by each
outstanding option and the exercise price per share thereof (but not the total
price), and each such option, shall all be proportionately adjusted for any
increase or decrease in the number of issued Common Shares of the Company
resulting from a split-up or consolidation of shares or any like capital
adjustment, or the payment of any share dividend out of the ordinary course.

6.1         EFFECT OF LIQUIDATION OR REORGANIZATION

      (a)   Cash, Shares or Other Property for Shares

            Except as provided in subsection 6.1(b) upon a merger (other than a
            merger of the Company in which the holders of Common Shares
            immediately prior to the merger have the same proportionate
            ownership of Common Shares in the surviving corporation immediately
            after the merger), consolidation, acquisition of property or stock,
            separation, reorganization (other than a mere reincorporation or the
            creation of a holding company) or liquidation of the Company, as a
            result of which the shareholders of the Company, receive cash,
            shares or other property in exchange for or in connection with their
            Common Shares, any option granted hereunder shall terminate, but the
            Optionee shall have the right immediately prior to any such merger,
            consolidation, acquisition of property or shares, separation,
            reorganization or liquidation to exercise such Optionee's option to
            the extent the vesting requirements set forth in the option
            agreement have been satisfied.

      (b)   Conversion of Options on Shares for Share Exchange

            If the shareholders of the Company receive shares in the capital of
            another corporation ("Exchange Shares") in exchange for their Common
            Shares in any transaction involving a merger (other than a merger of
            the Company in which the holders of Common Shares immediately prior
            to the merger have the same proportionate ownership of Common Shares
            in the surviving corporation immediately after the merger),
            consolidation, acquisition of property or shares, separation or
            reorganization (other than a mere reincorporation or the creation of
            a holding company), all options granted hereunder shall be converted
            into options to purchase Exchange Shares unless the Company and the
            corporation issuing the Exchange Shares, in their sole discretion,
            determine that any or all such options granted hereunder shall not
            be converted into options to purchase Exchange Shares but instead
            shall terminate in accordance with the provisions of subsection
            6.1(a). The amount and price of converted options shall be
            determined by adjusting the amount and price of the options granted
            hereunder in the same proportion as used for determining the number
            of Exchange Shares the holders of the Common Shares receive in such
            merger, consolidation, acquisition or property or stock, separation
            or reorganization. Unless accelerated by the Board, the vesting
            schedule set forth in the option agreement shall continue to apply
            to the options granted for the Exchange Shares.

6.2         FRACTIONAL SHARES

            In the event of any adjustment in the number of shares covered by
any option, any fractional shares resulting from such adjustment shall be
disregarded and each such option shall cover only the number of full shares
resulting from such adjustment.

6.3         DETERMINATION OF BOARD TO BE FINAL

            All Section 6 adjustments shall be made by the Board, and its
determination as to what adjustments shall be made, and the extent thereof,
shall be final, binding and conclusive.

7.          SECURITIES REGULATION

            Shares shall not be issued with respect to an option granted under
this Plan unless the exercise of such option and the issuance and delivery of
such shares pursuant thereto shall comply with all relevant provisions of law,
including without limitation the SECURITIES ACT (Ontario) and the SECURITIES ACT
(Alberta), any applicable provincial and state securities laws, the U.S.
SECURITIES ACT OF 1933, as amended, the Exchange Act, the rules and regulations
promulgated thereunder, and the requirements of any stock exchange upon which
the shares may then be listed, and shall be further subject to the approval of
counsel for the Company with respect to such compliance, including the
availability of an exemption from registration for the issuance and sale of any
shares hereunder. Inability of the Company to obtain from any
<PAGE>
                                      - 8 -

regulatory body having jurisdiction, the authority deemed by the Company's
counsel to be necessary for the lawful issuance and sale of any shares hereunder
or the unavailability of an exemption from registration for the issuance and
sale of any shares hereunder shall relieve the Company any liability in respect
of the nonissuance or sale of such shares as to which such requisite authority
shall not have been obtained.

            As a condition to the exercise of an option, the Company may require
the Optionee to represent and warrant at the time of any such exercise that the
shares are being purchased only for investment and without any present intention
to sell or distribute such shares if, in the opinion of counsel for the Company,
such a representation is required by any relevant provision of the
aforementioned laws. At the option of the Company, a stop-transfer order against
any shares may be placed on the official stock books and records of the Company,
and a legend indicating that the shares may not be pledged, sold or otherwise
transferred unless an opinion of counsel is provided (concurred in by counsel
for the Company) stating that such transfer is not in violation of any
applicable law or regulation, may be stamped on share certificates in order to
assure exemption from registration. The Plan Administrator may also require such
other action or agreement by the Optionees as may from time to time be necessary
to comply with the federal and state securities laws. THIS PROVISION SHALL NOT
OBLIGATE THE COMPANY TO UNDERTAKE REGISTRATION OF THE OPTIONS OR SHARES
HEREUNDER.

            Should any of shares of the Company of the same class as the shares
subject to options granted hereunder be listed on a securities exchange or other
securities trading facility, all shares issued hereunder if not previously
listed on such exchange or facility shall be authorized by that exchange or
facility for listing thereon prior to the issuance thereof.

8.          AMENDMENT AND TERMINATION

8.1         BOARD ACTION

            The Board may at any time suspend, amend or terminate this Plan,
            subject to, in the case of amendments, to such amendments being
            pre-cleared with The Toronto Stock Exchange provided that except as
            set forth in Section 6, the approval of the holders of a majority of
            the Company's outstanding voting shares, voting either in person or
            by proxy at a duly held shareholders' meeting is necessary within 12

            Any amendment made to this Plan which would constitute a
"modification" to incentive stock options outstanding on the date of such
amendment, shall not be applicable to such outstanding incentive stock options,
but shall have prospective effect only, unless the Optionee agrees otherwise.

8.2         AUTOMATIC TERMINATION

            Unless sooner terminated by the Board, this Plan shall terminate ten
years from the earlier of:

      (a)   the date on which this Plan is adopted by the Board; or

            Company.

No option may be granted after such termination or during any suspension of this
Plan. The amendment or termination of this Plan shall not, without the consent
of the option holder, alter or impair any rights or obligations under any option
theretofore granted under this Plan.

9.          EFFECTIVENESS OF THIS PLAN

            This Plan shall become effective upon adoption by the Board so long

amended to reflect the provisions of this Section 2.4.
