                              NOTES AND DEFINITIONS

The determination of oil and natural gas reserves involves the preparation of
estimates that have an inherent degree of associated uncertainty. Categories of
proved, probable and possible reserves have been established to reflect the
level of these uncertainties and to provide an indication of the probability of
recovery.

The estimation and classification of reserves requires the application of
professional judgment combined with geological and engineering knowledge to
assess whether or not specific reserves classification criteria have been
satisfied. Knowledge of concepts including uncertainty and risk, probability,
statistics and deterministic and probabilistic estimation methods is required to
properly use and apply reserves definitions.

"RESERVES" are estimated remaining quantities of oil, natural gas and related
substances anticipated to be recoverable from known accumulations, from a given
date forward, based on (a) analysis of drilling, geological, geophysical and
engineering data; (b) the use of established technology; and (c) specified
economic conditions, which are generally accepted as being reasonable and shall
be disclosed. Reserves are classified according to the degree of certainty
associated with the estimates.

"PROVED" reserves are those reserves that can be estimated with a high degree of
certainty to be recoverable. It is likely that the actual remaining quantities
recovered will exceed the estimated proved reserves. Nine out of ten times,
proved reserves are likely to increase.

"DEVELOPED PRODUCING" reserves are those reserves that are expected to be
recovered from completion intervals open at the time of the estimate. These
reserves may be currently producing or, if shut-in, they must have previously
been on production and the date of resumption of production must be known with
reasonable certainty.

"DEVELOPED NON-PRODUCING" reserves are those reserves that either have not been
on production, or have previously been on production, but are shut-in and the
date of resumption of production is unknown.

"UNDEVELOPED" reserves are those reserves expected to be recovered from known
accumulations where a significant expenditure, when compared to the cost of
drilling a well, is required to render them capable of production. They must
fully meet the requirements of the reserves classification (proved, probable,
possible) to which they are assigned.

<PAGE>

In multi-well pools, it may be appropriate to allocate total pool reserves
between the developed and undeveloped categories or to sub-divide the developed
reserves for the pool between developed producing and developed non-producing.
This allocation should be based on the estimator's assessment as to the reserves
that will be recovered from specific wells, facilities and completion intervals
in the pool and their respective development and production status.

"PROBABLE" reserves are those additional reserves that are less certain to be
recovered than proved reserves. It is equally likely that the actual remaining
quantities recovered will be greater or less than the sum of the estimated
proved plus probable reserves.

The following terms, when used in this document, have the following meanings, as
set forth in National Instrument 51-101:

"ASSOCIATED GAS" means the gas cap overlying a crude oil accumulation in a
reservoir.

"CONSTANT PRICES AND COSTS" means prices and costs used in an estimate that
are:

        (a)       the company's prices and costs as at the effective date of the
                  estimation, held constant throughout the estimated lives of
                  the properties to which the estimate applies; and

        (b)       if, and only to the extent that, there are fixed or presently
                  determinable future prices or costs to which the company is
                  legally bound by a contractual or other obligation to supply a
                  physical product, including those for an extension period of a
                  contract that is likely to be extended, those prices or costs
                  rather than the prices and costs referred to in paragraph (a).

For the purpose of paragraph (a), the reporting issuer's prices will be the
posted price for oil and the spot price for gas, after historical adjustments
for transportation, gravity and other factors.

"COMPANY" or "COMPTON" or "WE" means Compton Petroleum Corporation.

"CRUDE OIL" or "OIL" means a mixture that consists mainly of pentanes and
heavier hydrocarbons, which may contain sulphur and other non-hydrocarbon
compounds, that is recoverable at a well from an underground reservoir and that
is liquid at the conditions under which its volume is measured or estimated. It
does not include solution gas or natural gas liquids.

"DEVELOPMENT COSTS" means costs incurred to obtain access to reserves and to
provide facilities for extracting, treating, gathering and storing the oil and
gas from the reserves. More specifically, development costs, including
applicable operating costs of support equipment and facilities and other costs
of development activities, are costs incurred to:

        (a)       gain access to and prepare well locations for drilling,
                  including surveying well locations for the purpose of
                  determining specific development drilling sites, clearing
                  ground, draining, road building, and relocating public roads,
                  gas lines and power lines, to the extent necessary in
                  developing the reserves;

        (b)       drill and equip development wells, development type
                  stratigraphic test wells and service wells, including the
                  costs of platforms and of well equipment such as casing,
                  tubing, pumping equipment and the wellhead assembly;

        (c)       acquire, construct and install production facilities such as
                  flow lines, separators, treaters, heaters, manifolds,
                  measuring devices, production storage tanks, natural gas
                  cycling and processing plants and central utility and waste
                  disposal systems; and

        (d)       provide improved recovery systems.

"DEVELOPMENT WELL" means a well drilled inside the established limits of an oil
or gas reservoir, or in close proximity to the edge of the reservoir, to the
depth of a stratigraphic horizon known to be productive.

"EUB" means the Alberta Energy and Utilities Board.

"EXPLORATION COSTS" means costs incurred in identifying areas that may warrant
examination and in examining specific areas that are considered to have
prospects that may contain oil and gas reserves, including costs of drilling
exploratory wells and exploratory type stratigraphic test wells. Exploration
costs may be incurred both before acquiring the related property (sometimes
referred to in part as "prospecting costs") and after acquiring the property.
Exploration costs, which include applicable operating costs of support equipment
and facilities and other costs of exploration activities, are:

        (a)       costs of topographical, geochemical, geological and
                  geophysical studies, rights of access to properties to conduct
                  those studies and salaries and other expenses of geologists,
                  geophysical crews and others conducting those studies
                  (collectively sometimes referred to as "geological and
                  geophysical costs");

        (b)       costs of carrying and retaining unproved properties, such as
                  delay rentals, taxes (other than income and capital taxes) on
                  properties, legal costs for title defense and the maintenance
                  of land and lease records;

or a stratigraphic test well.

"FIELD" means an area consisting of a single reservoir or multiple reservoirs
all grouped on or related to the same individual geological structural feature
and/or stratigraphic condition. There may be two or more reservoirs in a field
that are separated vertically by intervening impervious strata or laterally by
local geologic barriers or both. Reservoirs that are associated by being in
overlapping or adjacent fields may be treated as a single or common operational
field. The geological terms "structural feature" and "stratigraphic condition"
are intended to denote localized geological features, in contrast to broader
terms such as "basin", "trend", "province", "play" or "area of interest".

"FUTURE PRICES AND COSTS" means future prices and costs that are:

                  determinable future prices or costs to which the Company is
                  legally bound by a contractual or other obligation to supply a
                  physical product, including those for an extension period of a
                  contract that is likely to be extended, those prices or costs
                  rather than the prices and costs referred to in paragraph (a).

"FUTURE INCOME TAX EXPENSES" means future income tax expenses estimated
year-by-year:

        (a)       making appropriate allocations of estimated unclaimed costs
                  and losses carried forward for tax purposes, between oil and
                  gas activities and other business activities;

        (b)       without deducting estimated future costs (such as Crown
                  royalties) that are not deductible in computing taxable
                  income;

        (c)       taking into account estimated tax credits and allowances; and

                                      -5-

                  which the Company has an interest.

"NATURAL GAS" means the lighter hydrocarbons and associated non-hydrocarbon
substances occurring naturally in an underground reservoir, which under
atmospheric conditions are essentially gases but which may contain natural gas
liquids. Natural gas can exist in a reservoir either dissolved in crude oil
(solution gas) or in a gaseous phase (associated gas or non-associated gas).
Non-hydrocarbon substances may include hydrogen sulphide, carbon dioxide and
nitrogen.

                  area of properties in which the Company has an interest
                  multiplied by the working interest owned by the Company.

"NON-ASSOCIATED GAS" means an accumulation of natural gas in a reservoir where
there is no crude oil.

"OPERATING COSTS" or "PRODUCTION COSTS" means costs incurred to operate and
maintain wells and related equipment and facilities, including applicable
operating costs of support equipment, facilities and other costs of operating
and maintaining those wells and related equipment and facilities.

"PRODUCTION" means recovering, gathering, treating, field or plant processing
(for example, processing gas to extract natural gas liquids) and field storage
of oil and gas.

"PROPERTY" includes:

        (a)       fee ownership or a lease, concession, agreement, permit,
                  licence or other interest representing the right to extract

                  properties or otherwise serves as producer of the underlying
                  reserves (in contrast to being an independent purchaser,
                  broker, dealer or importer). A property does not include
                  supply agreement or contracts that represent a right to
                  purchase, rather than extract, oil or gas.

"PROPERTY ACQUISITION COSTS" means costs incurred to acquire a property directly
by purchase or lease, or indirectly by acquiring another corporate entity with

production at the present time.

"SOLUTION GAS" means natural gas dissolved in crude oil.

"STRATIGRAPHIC TEST WELL" means a geologically directed drilling effort, to
obtain information pertaining to a specific geologic condition. Ordinarily, such
wells are drilled without the intention of being completed for hydrocarbon
production. They include wells for the purpose of core tests and all types of
expendable holes related to hydrocarbon exploration. Stratigraphic test wells
are classified as (a) "exploratory type" if not drilled into a proved property;
or (b) "development type", if drilled into a proved property. Development type
stratigraphic wells are also referred to as "evaluation wells".

                           FORWARD LOOKING STATEMENTS

This Annual Information Form may contain certain forward looking statements
under the meaning of applicable securities laws. Forward looking statements
include estimates, plans, expectations, opinions, forecasts, projections,
guidance or other statements that are not statements of fact. Although Compton
believes that the expectations reflected in such forward looking statements are
reasonable, it can give no assurance that such expectations will

                                      -7-
<PAGE>

prove to have been correct. There are many factors that could cause forward
looking statements not to be correct, including risks and uncertainties inherent
in the Company's business. These risks include, but are not limited to: crude
oil and natural gas price volatility, exchange rate fluctuations, availability
of services and supplies, operating hazards and mechanical failures,
uncertainties in the estimates of reserves and in projections of future rates
of production and timing of development expenditures, general economic
conditions, and the actions or inactions of third-party operators. The Company's
forward looking statements are expressly qualified in their entirety by this
cautionary statement.

                               CORPORATE STRUCTURE

NAME AND INCORPORATION

Compton was incorporated by articles of incorporation pursuant to the provisions
of the Business Corporations Act (Alberta) on October 15, 1992, as 544201
Alberta Ltd. The articles were amended on April 13, 1993, to change the
Company's name to Compton Petroleum Corporation and the Company commenced active
business operations in July 1993. The articles were amended on November 21, 1994
and March 1, 1996, in order to remove the private company restrictions contained
in the articles. A further amendment was made to the articles on September 1,
1998, in order to create a class of preferred shares issuable in series.

The Company's head and principal office is located at Suite 3300, 425 - 1st
Street S.W., Fifth Avenue Place, East Tower, Calgary, Alberta, Canada, T2P 3L8.
Compton's registered office is located at Suite 3000, 237 - 4th Avenue, S.W.,
Fifth Avenue Place, West Tower, Calgary, Alberta, Canada, T2P 4X7.

Effective January 31, 2001, a general partnership called Compton Petroleum was
formed under the laws of Alberta between Compton and Compton's wholly owned
subsidiary 867791 Alberta Ltd. On July 16, 2001, the partnership agreement was
amended to include Hornet Energy Ltd. Each partner has contributed a majority of
its producing assets to the partnership. The majority of Compton's production
activities are carried out through the partnership.

Effective May 2, 2003, MPP Ltd. ("MPP LTD."), a wholly-owned subsidiary of the
Company, was formed under the laws of Alberta. On June 16, 2003, MPP Ltd., as
general partner, and 1051940 Alberta Ltd., as limited partner, formed a limited
partnership called the Mazeppa Processing Partnership. The Mazeppa Processing
Partnership owns, among other assets, the Mazeppa and Gladys gas plants.


                       GENERAL DEVELOPMENT OF THE BUSINESS

Compton is an Alberta based independent public company actively engaged in the
exploration, development and production of natural gas, ngls and crude oil in
the Western Canadian Sedimentary Basin (the "WCSB") in Canada. The Company's
capital stock is listed and trades on the Toronto Stock Exchange (the "TSX")
under the trading symbol "CMT", and is included in both the S&P/TSX Composite
Index and the TSX Mid-Cap Index.

Compton commenced operations in 1993 with $1 million of share capital, a small
dedicated technical team and a large seismic database. The objective was to
build a company through internal, full cycle exploration, complemented by
strategic acquisitions. Compton's goal was to create a company capable of long
term sustained growth with a primary focus on natural gas. Compton's focus and
strategy have remained unchanged since conception.

THREE YEAR HISTORY

In 2002, Compton continued to focused on the exploration and development of its
internally generated prospects. The Company's $155 million capital program
included the drilling of 87 gross (64 net) wells with a success rate of 90%.
Compton's total established reserves increased 19.8 mmboe from 83.7 mmboe to
103.5 mmboe during 2002.

During 2002, the Company acquired a 50% working interest and operatorship of a
30 mmcf/d natural gas plant, 95 sections of contiguous undeveloped lands and
1,911 mboe of established, deep tight natural gas reserves at Callum. In
December 2002, Compton expanded its land position at Niton through a swap for
100 sections of high working

                                      -8-
<PAGE>

interest lands for non-operated minor working interests in the southern Peace
River Arch area. Both Niton and Callum are now core areas for Compton.

In 2003, Compton focused on the resolution of pipeline and facility constraints
in its Southern Alberta core area. The Mazeppa Processing Partnership purchased
the Mazeppa and Gladys natural gas plants with related compression facilities
and pipelines in Southern Alberta. The partnership is managed and controlled by
Compton and provided Compton flexibility to pursue and accelerate various
processing alternatives, including plant expansions. The Hooker pipeline system
was expanded to 80 mmcf/d and natural gas production from Brant was offloaded to
the ATCO sales pipeline. With processing restrictions removed, Compton intends
to continue to aggressively explore lands adjacent to the Mazeppa, Gladys and
Brant pipeline and plant infrastructures.

The Company continued to pursue the exploration and development of its assets
and prospects in 2003. The Company's capital program totaled approximately $285
million, including the consolidation of the Mazeppa gas plant. The Company
drilled 168 gross (134 net) wells in 2003 with an 83% success rate.

Expansion of the Mazeppa gas plant from 90 mmcf/d to 135 mmcf/d through the
addition of 45 mmcf/d of additional sweet gas processing capacity, was completed
and operational on June 1, 2004. Compton's processing capacity in Southern
Alberta is now 200 mmcf/d and free of restrictions. The Mazeppa Processing
Partnership completed the $75 million external financing of the acquisition,
expansion and operations of the Mazeppa facilities and repaid funds borrowed
from Compton.

Compton continues to be very optimistic about its five separate resource plays
including Coalbed Methane in the Horseshoe Canyon (Edmonton Formation), plains
Belly River, thrusted foothills Belly River, Hooker Basal Quartz sands in
Southern Alberta and the Gething/Rock Creek sands at Niton in Central Alberta.
In 2004, Compton drilled 186 gross (146 net) wells with a 90% success rate. Of
the wells drilled, 77% were classified as development wells and 33% were
classified as exploratory wells. The increasing percentage of development wells
is reflective of the increasing maturity of the Company's oil and natural gas
plays. Capital expenditures totaled $323 million in 2004.

In 2004, Compton added approximately 26 mboe to its proved plus probable
reserves through drilling successes, acquisitions and extensions. Total proved
plus probable reserves increased 22% from the prior year to 145 mboe.

                           DESCRIPTION OF THE BUSINESS

EXPLORATION AND PRODUCTION OPERATIONS

Compton's exploration, development and exploitation activities are concentrated
principally in three core areas: 1) Southern Alberta targeting the plains Belly
River, Horseshoe Canyon coalbed methane, Hooker Basal Quartz and thrusted,
foothills Belly River at Callum; 2) Central Alberta targeting the Gething/Rock
Creek at Niton; and 3) the Peace River Arch area producing from the Charlie Lake
pool at Cecil/Worsley. These areas are the geographic focus of Compton's seismic
database and are areas in which Compton's Management ("MANAGEMENT") and staff
have significant technical expertise and operational experience.

MAZEPPA PROCESSING PARTNERSHIP

In June of 2003, Mazeppa Processing Partnership ("MPP") acquired certain
midstream assets from an independent third party. The assets consist of major
natural gas gathering and processing facilities in southern Alberta. Compton
does not have an ownership position in MPP. Through a management agreement,
Compton manages the activities of MPP and is therefore considered to be the
primary beneficiary of MPP's operations. As a result, Compton consolidates the
accounts of MPP for reporting purposes in accordance with the guidelines issued
by the Accounting Standards Board, in Accounting Guideline AcG-15,
"Consolidation of Variable Interest Entities." The results of the midstream
activities are immaterial to Compton's consolidated financial condition.

EMPLOYEES

As at December 31, 2004, Compton had 115 full-time employees in its Calgary
office and 33 full-time employees at field locations.

                                      -9-

BUSINESS PLAN AND OPERATING STRATEGY

The Company's business plan is to grow Compton's reserves and maximize
production and cash flow from its core geographic areas and other areas where
Compton has technical expertise. Management believes the Company is implementing
this objective by focusing on the efficient exploration, development and
exploitation of its properties, controlling operating costs, adding economic
reserves and production and making strategic acquisitions in its core areas.
Compton has experienced, professional, management, technical and support staff
sufficient to carry out its business plan and its current exploration,
exploitation, development, production, engineering, financial and administrative
functions.

The Company's operating strategy includes the components set forth below:

CONCENTRATE ON CORE GEOGRAPHIC AREAS. The Company has established and is
expanding its core areas within the WCSB. This geographic core area focus
provides Compton with a balanced portfolio of exploitation, exploration and
development prospects. Compton has developed and continues to develop its
natural gas and crude oil reserves primarily through the internal generation of
opportunities. This focus provides the Company with the opportunity for high
working interests, enabling Compton to control the timing of capital
expenditures and facilitates the efficient management of its activities.
Compton's intention is to generate exploration opportunities and to
significantly increase its undeveloped land base within the WCSB.

FOCUS ON NATURAL GAS. Compton has gained considerable technical expertise and
achieved significant success in exploring for deeper, larger, low decline
natural gas reservoirs. The Company plans to continue to focus on finding and
developing long life natural gas reserves.

PURSUE FULL CYCLE EXPLORATION COMPLEMENTED BY SELECTIVE ACQUISITIONS. The
Company plans to continue to reinvest internally generated cash flow to fund the
growth of its exploration and development programs and to further increase
Compton's undeveloped land base to maintain a growing inventory of drilling
prospects in its core geographic areas. The Company has also successfully
completed and integrated a series of strategic acquisitions to grow Compton's
reserves and production base and enhance the level of technical expertise in its
core areas. Depending on commodity price cycles, the Company may defer
exploration projects and enhance its operations and prospects through strategic
acquisitions.

CONTROL OF INFRASTRUCTURE AND OPERATORSHIP. The Company believes that control
over gathering and processing infrastructure and operatorship of drilling
programs will continue to be critical to the success of Compton's full-cycle
exploration program. Compton currently owns or has access to critical
infrastructure in each of its three primary producing areas. Compton operates
approximately 75% of its existing production and, as of December 31, 2004, had a
72% average working interest in its undeveloped lands. This position allows the
Company to exercise discretion in determining the timing and methodology of
Compton's ongoing exploitation, exploration and development programs. The
Company expects to continue to expand its position in its core operating areas
to maximize operating efficiencies and maintain control over ongoing capital
programs.

MAINTAIN A LARGE PORTFOLIO OF UNDEVELOPED LAND AND SEISMIC DATABASE. As of
December 31, 2004, the Company has assembled a significant portfolio of
undeveloped land and has working interests in 1,019,854 (729,429 net) acres of
undeveloped land. Management believes that Compton's existing portfolio of
undeveloped land is sufficient to produce at least five years of internally
generated exploration and development prospects.

Additionally, the Company holds a quality, complementary seismic database. The
Company's rights to approximately 100,700 kilometres of two-dimensional ("2D")
seismic and 2,200 square kilometres of three-dimensional ("3D") seismic are
concentrated primarily in areas throughout Compton's core operating areas within
Alberta. Compton will continue to utilize the seismic database to evaluate and
generate future prospects and to assist in maintaining growth of the Company.

MAINTAIN FINANCIAL FLEXIBILITY. The Company is committed to maintaining
financial flexibility to allow Compton to pursue its full cycle exploration
program in periods of low commodity prices. The Company intends to maintain
flexibility to respond to opportunities for strategic acquisitions as they
arise. Compton has historically funded its


                                      -10-
<PAGE>

exploration and development capital program through internally generated cash
flow and has financed acquisitions through debt, the issuance of common shares
or a combination thereof.

PRINCIPAL PROPERTIES

SOUTHERN ALBERTA

Southern Alberta continues to be the focus of Compton's activities. The Company
has approximately 1,220 (998 net) sections of land. The area is prospective for
multiple zones, including the plains Belly River, foothills type, multiple
thrusted Belly River at Callum, Basal Quartz at Hooker and the
Wabamun/Crossfield. Additional upside exists in the shallower Edmonton
Formation/Horseshoe Canyon Coals. In 2004, Compton drilled 101 gross (88 net)
wells in Southern Alberta with a 94% success rate. The Company plans to spend
$251 million in Southern Alberta in 2005 and drill 269 wells.

HORSESHOE CANYON COAL BED METHANE

Compton holds approximately 960 net sections of land in Southern Alberta within
the dry Horseshoe Canyon Coal Bed Methane ("CBM") fairway. Following an internal
geological assessment of the CBM potential in Compton's lands, the Company is
proceeding to quantify the CBM resource base.

During the third quarter of 2004, the Company re-completed six existing Belly
River wells targeting the uphole Horseshoe Canyon Coals, primarily at Centron,
Gladys and Brant. Results were similar to competitor's CBM wells immediately
north of Compton's acreage. Preliminary internal resource evaluations of the
Edmonton/Horseshoe Canyon Coals estimate gas-in-place is eight to nine bcf per
section. Six to eight wells will be required to fully develop the reserves,
assuming a recovery rate of 50-60%.

Compton is in a unique position regarding future Edmonton/Horseshoe Canyon
development. The Company has previously drilled 250 Belly River wells across the
Southern Alberta core area, primarily on single section spacing. These existing
wells were drilled through the Edmonton formation targeting the Belly River
zone. Behind pipe are unperforated coals and Edmonton sands of similar quality
and quantity to successful competitor CBM plays on lands that lie immediately to
the north and south of Compton's landholdings. With the 2005 budget planning an
additional 186 Belly River wells, Compton will have over 400 wellbores available
for uphole CBM recompletions by year end 2005. The cost to drill, complete,
equip and tie-in a well targeting solely Edmonton/CBM is $400,000, whereas the
cost to workover an existing Belly River well for CBM is only $150,000-$200,000.

Compton currently has an extensive network of low pressure pipelines and
strategically placed compressors throughout Southern Alberta to produce the
Company's Belly River gas wells. As a result little infrastructure will be
required to initiate Edmonton/CBM production.

Compton has insignificant CBM reserves booked as at December 31, 2004, despite
having five wells on continuous production since year end. Quantifying the
reserve and delivery potential of the Edmonton/CBM over Compton's large land
spread is a key objective in 2005. Compton has six CBM pilot projects underway,
with results expected by the middle of the fourth quarter of 2005. The pilots
will not delay Compton's plan to continue uphole recompletions of existing Belly
River wells.

PLAINS BELLY RIVER AT CENTRON, GLADYS AND BRANT

The plains Belly River consists of five to six multi-stacked sands, which occur
extensively over 960 net sections of Compton's Southern Alberta core area. The
Company has an average working interest of 90% in this play. Wells produce
approximately 150-200 mcf/d and cost $500,000 to drill, complete, equip and
tie-in. Based on internal work, the Company estimates gas-in-place could be in
the range of six to eleven bcf and recoveries may average 0.6+ bcf per well.
Ultimate recoveries will depend on well density. Compton believes that four to
six wells per section will optimize recovery of the Belly River gas.

                                      -11-
<PAGE>

In 2004, Compton drilled 60 gross (54 net) wells across the Centron, Gladys and
Brant areas with all wells encountering multiple pay sections. To date, the
Company has drilled 250 wells targeting the Belly River sands. The pipeline and
compression system that Compton owns and operates in Southern Alberta is
extensive.

Historically the majority of Compton's drilling has been on one section spacing.
During the second half of 2004, Compton received approval to proceed with two
wells per section on seven townships of land. This effectively doubles the
Company's current plains Belly River drilling inventory. The Company plans to
drill 183 Belly River wells in 2005.

CALLUM THRUSTED BELLY RIVER

Applying expertise developed in the Company's plains Belly River exploration,
Compton is targeting thrusted, stacked multiple Belly River tight sandstones at
Callum. The Company has a 60% working interest in 110 sections of land on trend.
Based upon limited initial drilling results, the potential gas in place is
estimated to be 80 bcf per section, with ultimate recoveries depending upon well
density. Compton has an average working interest of 60% in the play.

Drilling in the Callum area is completed from pads with an eight well
capability. Each new well costs approximately $2.5 million to drill, complete,
equip and tie-in, with six to eight wells required per section to develop this
play. Seven wells to date have been drilled in the feature, with recent
completions averaging approximately 1 mmcf/d per well.

In 2004, three directional wells were drilled from a pad constructed immediately
south of the Callum gas plant, plus two additional wells north of the plant.
Results were encouraging, however, it is apparent that completion design is the
key to unlocking this technically challenging play. Callum has the potential to
become a very significant resource play for Compton and time spent assessing
completion techniques is critical to the future development of this play.

Quarter section spacing over nine sections was approved by the EUB in the third
quarter of 2004. Site assessment for the next drilling pad was completed in the
fourth quarter of 2004, with drilling expected to commence early in 2005.
Compton plans to drill 21 wells at Callum in 2005.

HOOKER BASAL QUARTZ

The Hooker trend targets tight Lower Cretaceous Basal Quartz sandstones. This
play covers an extensive area of approximately 244 net sections, with Compton's
working interest averaging 75%. Current production extends over four townships,
with the outer boundaries of the play continuing to be expanded. The majority of
the 110 gross (89 net) gas wells drilled to date at Hooker were on single
section spacing, however, two wells per section spacing across 26 sections was
approved by the EUB in the third quarter of 2004. Further downspacing is being
applied for. Compton feels the pool can ultimately be drilled on three wells per
section spacing.

Wells cost an average of $1.5 million to drill, complete, equip and tie in,
while production averages 1 mmcf/d. Mapping by the Company suggests this play
has the potential to grow to nine townships with reserves in place of up to
15-20 bcf per section. The same work suggests the Hooker trend has the potential
to contain up to 1.5 tcf of gas-in-place potential, net to the Company. With
recoveries of 65%, Hooker's resource potential is in excess of 500 bcf of net
gas reserves.

In 2004, 25 gross (22 net) gas wells were drilled, extending the pool boundary
five miles to the north and 1.5 miles to the southeast. The Company received
downspacing approval on the southeast Hooker extension and is currently
proceeding with an additional application for downspacing at the northern end of
Hooker. In 2005, the Company plans to drill 35 wells at Hooker.

SOUTHERN ALBERTA FACILITIES

On June 1, 2004, a 45 mmcf/d sweet gas expansion at the Mazeppa plant was
completed resulting in 90 mmcf/d sour and 45 mmcf/d sweet processing capacity.
Compton gained control and management of the Mazeppa and Gladys gas

                                      -12-
<PAGE>

plants and related infrastructure through the acquisition of the facilities by
Mazeppa Processing Partnership in July of 2003. With the completion of the
Mazeppa sweet gas expansion, Compton's working interest processing capacity in
Southern Alberta is now 200 mmcf/d. Available processing capacity will be
sufficient to accommodate the Company's production additions for the next few
years. Future expansions, when required, can be undertaken by Compton as
operator, ensuring timely completion.

CENTRAL ALBERTA

Central Alberta provides Compton with excellent exploration and development
drilling opportunities using similar techniques gained through years of
experience from Southern Alberta Deep Basin type, tight gas drilling. Compton
holds 757 (407 net) sections of land, the majority located approximately 100 km
West of Edmonton. In 2004 Compton drilled 46 gross (32 net) wells with an 83%
success rate. The Company plans to spend $68 million in Central Alberta in 2005
and drill 58 wells.

NITON GETHING

The Niton area is characterized by multi-zone, deep basin type targets analogous
to the Southern Alberta Hooker area. Compton's primary gas targets include Rock
Creek (Jurassic) and Gething. Secondary targets include Bluesky, Viking and
Cardium.

The Company has assembled 126 net sections, with an average working interest of
75%. In 2004, the Company drilled and cased 16 gross (15 net) gas wells. To
date, 30 gross gas wells have been drilled with average production of 1 mmcf/d
including liquids at an average cost of $1.5 million to drill, complete, equip
and tiein. The Company anticipates the gas-in-place could be in the range of
10-12 bcf per section, with a projected recovery of 75%.

In 2004, Compton received downspacing approval on 18 sections for two wells per
section, with further downspacing approval pending. The Company expects two to
three wells will be required to fully develop this area, with 26 wells planned
in 2005.

During the second quarter of 2004, Compton acquired all of the issued and
outstanding shares of Redwood Energy, Ltd., a junior oil and gas company active
in the Niton Area. Through the acquisition, the Company gained undeveloped
lands, workover opportunities on existing wells, reserves, production and
control of a 35 km gathering system, key to area development.

The Compton owned McLeod River gas plant was operating at maximum capacity in
the third quarter of 2004 as a result of the Company's successful drilling
program at Niton. The gas plant was expanded from 10 mmcf/d to 20 mmcf/d in the
fourth quarter of 2004. A 10 mmcf/d booster compressor at Niton was installed
and operational early in the third quarter of 2004.

PEACE RIVER ARCH

The Peace River Arch area, located north of Grande Prairie, contains multi-zone
potential for exploration and development opportunities. This area includes both
light oil production at Cecil/Worsley and natural gas exploration at Howard and
Pouce Coupe. The Company holds 306 (182 net) sections acres of land in the area.
In 2004, Compton drilled 39 gross (26 net) wells in the Arch with a 92% success
rate. The Company plans to spend $51 million in the area in 2005 and drill 56
wells.

CECIL/WORSLEY

Together, the Cecil and Worsley Charlie Lake pools are estimated to hold in
excess of 200 million barrels of oil-in-place. Compton drilled 10 wells at
Worsley in 2004, doubling the estimate of original oil-in-place. As a result of
the Company's success with the two existing waterflood pilots, Compton made an
application for a pool wide waterflood on the Charlie Lake H and J pool.

Approval was granted in February 2005. Waterflooding in the Worsley Charlie Lake
H and J pool is projected to increase the ultimate recovery rate from 5-7% to
15-17%. Pipelines in the Worsley area were expanded to prepare

                                      -13-
<PAGE>

for implementation of the full scale waterflood over the next two years. A
battery expansion was also completed to accommodate future drilling plans. In
2005, Compton anticipates drilling 39 Charlie Lake extension and infill wells at
Worsley.

Compton participated in drilling 12 horizontal Charlie Lake oil wells at Cecil
in 2004. The Company has a 40% working interest in the play, which is operated
by a major industry partner. The success of the Cecil program has prompted
Compton to expand the 2005 drilling program to 20 wells.

COMPETITIVE CONDITIONS

While the demand for natural gas continues to grow, production may be peaking.
Natural gas wells in the WCSB continued the trend of lower initial production
rates and higher first year decline rates, resulting in an overall increase of
decline rates in the WCSB. In order to maintain current production levels,
producers must increase drilling and pursue unconventional sources of natural
gas.

Unconventional sources of natural gas are necessary to offset conventional
natural gas declines and provide the production growth necessary to fulfill
increasing demand. Unconventional sources include coalbed methane, shale gas,
liquefied natural gas and tight gas. Tight gas, which comprises 80% of Compton's
reserves, is expected to be the largest unconventional form of natural gas
production in the future. The Canadian oil and natural gas industry is also
aggressively pursuing coal bed methane potential and the early results show
significant upside. These new resource plays require a large upfront land base,
technical expertise, experience and difficult project economics which puts more
pressure on the industry.

Drilling rigs, service rigs, equipment and experienced crews continue to operate
at or near maximum capacity, which has resulted in escalating drilling costs and
inefficiencies. Strong demand for experienced professionals has caused a
significant increase in salaries and workloads, further adding to inefficiency
in the industry. Land prices also continue to increase and are consuming an
increasing portion of annual budgets and adding considerably to finding,
development and acquisition ("FD&A") costs. Deeper drilling and more complex
plays have contributed to higher FD&A costs for the industry in general.
Additionally, the increasing complexity and ever changing government rules
regarding license applications, environmental and governance matters is adding
significantly to overall costs, workloads and timing of operations. The end
result is that while commodity prices are strong, the cost, effort and time of
doing business have also risen dramatically.

ENVIRONMENTAL PROTECTION

Compton believes in the importance of protecting the environment and is
committed to conducting all operations in a safe manner that minimizes
environmental impact. The Company is required to remove production equipment,
batteries, pipelines, gas plants and restore land at the end of oil and natural
gas operations. The Company estimates these costs in accordance with existing
laws, contracts and other policies and records an expense in the consolidated
financial statements over the useful life of the assets.

SEISMIC

The Company owns rights to copies of, and rights to utilize, large seismic
databases for its internal purposes. The proprietary rights of such databases
are owned mostly by third parties (although the proprietary rights of some
databases are owned by the Company). These databases include conventional 2-D
seismic covering 101,449 kilometres and 3-D seismic data shot over 3,063 square
kilometres. This data is concentrated primarily in areas throughout Compton's
core operating areas within Alberta. Additionally, the Company has rights to use
6,200 kilometres of seismic covering areas in southern Manitoba. These large
seismic databases are utilized by the Company's exploration team in exploration
and acquisition decisions of the Company.

                ADDITIONAL INFORMATION RELATING TO RESERVES DATA

UNDEVELOPED RESERVES

The following discussion generally describes the basis on which Compton
attributes proved and probable undeveloped reserves and its plans for developing
those undeveloped reserves.

PROVED UNDEVELOPED RESERVES

Proved undeveloped reserves are generally those reserves related to wells that
have been tested and not yet tied-in, wells drilled near the end of the fiscal
year or wells further away from the Company's gathering systems. In addition,
such reserves may relate to planned infill drilling locations. The majority of
these reserves are planned to be on stream within a two year timeframe.

PROBABLE UNDEVELOPED RESERVES

Probable undeveloped reserves are generally those reserves tested or indicated
by analogy to be productive infill drilling locations and lands contiguous to
production. The majority of these reserves are planned to be on stream within a
two year timeframe.

SIGNIFICANT FACTORS OR UNCERTAINTIES AFFECTING RESERVES DATA

The process of estimating reserves is complex. It requires significant judgments
and decisions based on available geological, geophysical, engineering and
economic data. These estimates may change substantially as additional data from
ongoing development activities and production performance becomes available and
as


                                      -21-
<PAGE>

economic conditions impacting oil and natural gas prices and costs change.
The reserve estimates contained herein are based on current production
forecasts, prices and economic conditions. Compton's reserves are evaluated by
Netherland Sewell.

As circumstances change and additional data becomes available, reserve estimates
also change. Estimates made are reviewed and revised, either upward or downward,
as warranted by the new information. Revisions are often required due to changes
in well performance, prices, economic conditions and governmental restrictions.

Although every reasonable effort is made to ensure that reserve estimates are
accurate, reserve estimation is an inferential science. As a result, subjective
decisions, new geological or production information and a changing environment
may impact these estimates. Revisions to reserve estimates can arise from
changes in year-end oil and natural gas prices, and reservoir performance. Such
revisions can be either positive or negative.

FUTURE DEVELOPMENT COSTS

The following table provides a summary of the development costs deducted in the
estimation of future net revenue attributable to each of the following reserves
categories:

Compton estimates that its internally generated cash flow will be sufficient to
fund the future development costs disclosed above. Compton typically has
available three sources of funding to finance its capital expenditure program:
(i) internally generated cash flow from operations; (ii) debt financing when
appropriate; and (iii) new equity issues, if available on favourable terms.

Compton expects to fund its total 2005 capital program with internally generated
cash flow, equity, bank debt and minor property dispositions.

</TABLE>

Approximately 113,638 net acres of undeveloped land could expire by December 31,
2005. However, the Company's 2005 exploration and development activities may
defer the expiry of a portion of these lands. Compton has approximately $54
million of work commitments associated with unproved properties.

FORWARD CONTRACTS

In 2004, Compton's realized average field price was $39.82/boe, comprised of
$6.46/mcf for natural gas and $43.21/bbl for liquids (crude oil and ngls). In
2003, the average field prices of natural gas and liquids were $6.01/mcf and
$34.39/bbl, respectively, for an average price of $35.66/boe.

Compton's natural gas production is sold under a combination of longer term
contracts with aggregators and short term daily or 30 day AECO indexed
contracts. Approximately 12% of the Company's natural gas production in 2004 was
committed to aggregators. The average aggregator price realized was
approximately $0.32/mcf less than the non-aggregator prices realized during the
year.

Compton's crude oil sales are priced at Edmonton postings and are typically sold
on 30 day evergreen arrangements. Ngls are bid out on an annual basis to
establish the most competitive pricing. The Company sells crude oil and ngls
primarily to refineries and marketers of crude oil and ngls.

From time to time, Compton may enter into hedging arrangements to mitigate
commodity price risk and take advantage of opportunistic pricing. In accordance
with Compton's policy, hedging programs will not exceed 50% of non-contracted
production.

ADDITIONAL INFORMATION CONCERNING ABANDONMENT AND RECLAMATION COSTS

Compton is required to remove production equipment, batteries, pipelines and
natural gas plants and to restore land at the end of oil and natural gas
operations. The Company estimates these costs in accordance with existing laws,
contracts and other policies. These obligations are initially measured at fair
value, which is the discounted future value of the liability. This fair value is
also capitalized as part of the cost of the related assets and amortized over
the useful life of the assets.

An independent environmental consulting firm was hired to assist Management in
the estimation of the Company's asset retirement obligations ("ARO"). ARO cost
calculations were derived from a combination of actual third party cost quotes,
EUB cost models and typical industry experience and practices. The deemed ARO
liability for Compton's 1,175 net well sites and facilities is the sum of the
calculated abandonment and reclamation liabilities adjusted for designated
status as active, inactive, abandoned or problem site. Information regarding
environmental remediation costs and other liability issues for site specific
concerns were derived from a review of historical audit and assessment reports
of sites and facilities. An inflation rate of 2.0% and a credit adjusted risk
free rate of 10.8% was used in the fair value calculation.

Total asset retirement costs, net of estimated salvage values, is $68 million or
$11 million when discounted at 10%. The undiscounted ARO associated with
pipelines and facilities is $45 million and is not deducted in estimating total
future net revenue, as calculated in the Company's reserve report. The Company
expects to pay $1 million dollars in ARO costs between 2005 and 2008.

TAX HORIZON

Based upon planned capital expenditure programs and current commodity price
assumptions, the Company will not be cash taxable until 2007.

CAPITAL EXPENDITURES

In 2004, Compton incurred $77 million of exploration costs and $196 million of
development costs. Additionally, $13 million was spent on proved property
acquisitions and $13 million was spent on unproved property acquisitions.

EXPLORATION AND DEVELOPMENT ACTIVITIES

The following table sets forth the number of crude oil, natural gas and service
wells drilled by the Company, or which the Company participated in drilling,
that are capable of production, as well as the number of dry and abandoned
wells, all expressed in terms of gross and net wells during the years ended
December 31, 2004 and 2003. Eight wells drilled in 2004 are standing cased wells
and are awaiting completion and testing. These wells are not included in the
following table.

                                    DIVIDENDS

The Company has neither declared nor paid any dividends on its common shares.
The Company intends to retain its earnings to finance growth and expand its
operations and does not anticipate paying any dividends on its common shares in
the foreseeable future.

                                CAPITAL STRUCTURE

Compton is authorized to issue an unlimited number of common shares and an
unlimited number of preferred shares, of which 127,071,986 common shares are
issued and outstanding as fully paid and non-assessable share as at March 23,
2005. No preferred shares are issued and outstanding as at March 23, 2005. The
following is a description of Company's common and preferred shares.

COMMON SHARES

Common shares have attached to them the following rights, privileges,
restrictions and conditions: (i) except for meetings at which only holders of
another specified class or series of shares of the Company are entitled to vote
separately as a class or series, each holder of a common share is entitled to
receive notice of, to attend and to vote at all meetings of the shareholders of
the Company; (ii) subject to the rights, privileges, restrictions and conditions
attached to any preferred shares, the holders of common shares are entitled to
receive dividends if, and when declared by the Directors of the Company; and
(iii) subject to the rights, privileges, restrictions and conditions attached to
any other class of shares of the Company, the holders of common shares are
entitled to share equally in the remaining property of the Company upon
liquidation, dissolution or winding-up of the Company.

PREFERRED SHARES

The preferred shares may be issued in one or more series, and the Directors are
authorized to fix the number of shares in each series and to determine the
designation, rights, privileges, restrictions and conditions attached to the
shares of each series. The preferred shares are entitled to a priority over the
common shares with respect to the payment of dividends and the distribution of
assets upon the liquidation, dissolution or winding-up of Compton.

SHAREHOLDER RIGHTS PLAN

Compton has a shareholder rights plan (the "Rights Plan") under the terms of a
shareholder rights plan agreement dated as of April 22, 2003 between Compton and
Computershare Trust Company of Canada, as rights agent. The Rights Plan is
designed to encourage the fair treatment of shareholders in connection with a
take-over bid for Compton. Rights issued under the Rights Plan become
exercisable when a person, and any related parties, acquires or announces its
intention to acquire 20% or more of the outstanding Common Shares without
complying with certain provisions set out in the Rights Plan or without approval
of the board of directors of Compton. Should such an acquisition or announcement
occur, each rights holder, other than the acquiring person and related parties,
will have the right to purchase Common Shares at a 50% discount to the market
price at that time.

                  AUDIT, FINANCE AND RISK COMMITTEE INFORMATION

The Charter of the Audit, Finance and Risk Committee is set forth in Schedule C.

COMPOSITION OF AUDIT, FINANCE AND RISK COMMITTEE

Chairman: John A. Thomson
Members: Mel F. Belich, Irvine J. Koop, John W. Preston and Jeffrey T. Smith

All members of the Audit, Finance and Risk Committee are independent, unrelated,
outside Directors. An "independent" director is a director who has no direct or
indirect material relationship with the Company (a material relationship is a
relationship which could, in the view of the Board, reasonably interfere with
the exercise of a director's independent judgment).


An "unrelated" Director is a director who is (a) not a member of Management and
is free from any interest and any business, family or other relationship which
could, or could reasonably be perceived to, materially interfere with the
Director's ability to act with a view to the best interests of the Company,
other than interests and relationships arising from shareholding, (b) not
currently or has not been, within the last three years, an officer, employee of
or material service provider to the Company or any of its subsidiaries or
affiliates, and (c) not a director, officer employee or significant shareholder

The audit related fees incurred in fiscal 2004 related to discussions regarding
the accounting treatment for MPP. Tax fees incurred in fiscal 2004 related to

were incurred to translate the Company's quarterly and annual reports into
French and discussions regarding requirements of the Sarbanes-Oxley Act.

The audit related fees incurred in fiscal 2003 related to the issuance of the
Company's U.S. dollar senior term notes in May 2002 as well as accounting policy
and research discussions. Tax fees incurred in fiscal 2003 related to the review

The Audit, Finance and Risk Committee of the Company considered these fees and
determined that they were reasonable and do not impact the independence of the
Company's auditors. Further, such Committee determined that in order to ensure
the continued independence of the auditors, only limited non-audit related
services would be provided to the Company by Grant Thornton LLP and in such
case, only with the prior approval of the Audit, Finance and Risk Committee. The
Committee has pre-approved Management to retain Grant Thornton LLP to provide
miscellaneous, minor, non-audit services in circumstances where it is not
feasible or practical to convene a meeting of the Audit, Finance and Risk
Committee, subject to an aggregate limit of $20,000 per quarter.

                                  RISK FACTORS

Compton's operations are subject to risks normally associated with the oil and
natural gas industry. The most important of these are set out below, together
with the strategies Compton employs to mitigate and minimize these risks.

INHERENT INDUSTRY RISK THAT EXPLORATION AND DEVELOPMENT PROGRAMS MAY NOT RESULT
IN ECONOMIC RESERVE ADDITIONS TO REPLACE PRODUCTION. Compton's strategies to
minimize this inherent risk include focusing on selected core areas in Western
Canada with high working interests and assuming operatorship of key facilities.
The Company utilizes a team of highly qualified professionals with expertise and
experience in these areas. Compton assesses strategic acquisitions to complement
existing activities while striving for a balance between exploration and lower
risk development and exploitation prospects.

FINANCIAL RISKS INCLUDING COMMODITY PRICES AND EXPENDITURE COSTS SHIFTING DUE TO
CHANGES IN MARKET CONDITIONS. Commodity prices are driven by supply, demand and
market forces outside the Company's influence. However, the Company's product
mix is diversified to reduce exposure to any one commodity's price movements.
Sales of oil and natural gas are aimed at various markets to avoid undue
exposure to any one market. When appropriate, Compton ensures that parental
guarantees or letter of credit are in place to minimize the impact in the event
of default.

Compton monitors and focuses its expenditures to reflect price and production
changes. Compton continuously scrutinizes market conditions and opportunities.
From time to time, the Company will employ financial instruments to manage
exposure related to Canada/U.S. dollar exchange rates and commodity prices.

The Company has commodity and fixed price contracts outstanding. The Company
considers longer term contracts with suppliers, where appropriate, to mitigate
shifts in costs resulting from changes in industry and market conditions.
Compton has no control over government intervention or taxation levels on the
industry.

It is likely that in the future the Company will be required to raise additional
capital via debt and/or equity financings in order to fully realize its
strategic goals and business plans. Compton's ability to raise additional
capital will depend upon a number of factors, such as general economic and
market conditions that are beyond its control. If Compton is unable to obtain
additional financing or to obtain it on favorable terms, the Company might be
required to forego attractive business opportunities. Compton is committed to
maintaining a strong balance sheet, combined with a flexible capital expenditure
program that can be adjusted to capitalize on or reflect acquisition
opportunities or a tightening of liquidity sources.

MECHANICAL AND OPERATIONAL RISKS ASSOCIATED WITH THE DRILLING FOR, PRODUCTION
AND PROCESSING OF NATURAL GAS AND CRUDE OIL, INCLUDING DAMAGE TO THE COMPANY'S
EQUIPMENT AND THE LIABILITY ASSOCIATED WITH AN OCCURRENCE OR MALFUNCTION.
Compton manages operational risks by employing skilled professionals utilizing
leading edge technology and conducting regular maintenance and training
programs. The Company has both an operational emergency response plan and an
operational safety manual. In addition, a comprehensive insurance program is
maintained to mitigate risks and protect against significant losses where
possible.

                                      -32-
<PAGE>

Compton operates in accordance with all applicable environmental legislation.
The Company strives to maintain or surpass compliance with such regulations and
works with government agencies, landholders and other parties to minimize the
environmental impact of its activities.

Compton is also subject to various government-imposed regulatory risks, some of
which are beyond the Company's control. Compton has established an Engineering,
Reserves and Operations Committee to ensure that employees and the environment
are protected while the Company is engaged in its exploration and development
activities. Policies and procedures have been established to ensure
environmental protection standards are maintained and standards of operating
practice are designed to minimize risk to employees and the environment.

                                   SCHEDULE A

                     REPORT ON RESERVES DATA BY INDEPENDENT
                          QUALIFIED RESERVES EVALUATOR

To the Board of Directors of Compton Petroleum Corporation (the "COMPANY"):

1.       We have evaluated the Company's reserves data as at December 31, 2004.
         The reserves data consist of the following:

         (a)      (i)      proved and proved plus probable oil and gas
                           reserves estimated as at December 31, 2004 using
                           forecast prices and costs; and

                  (ii)     the related estimated future net revenue; and

         (b)      (i)      proved and proved plus probable oil and gas
                           reserves estimated as at December 31, 2004 using
                           constant prices and costs; and

                  (ii)     the related estimated future net revenue.

2.       The reserves data are the responsibility of the Company's Management.
         Our responsibility is to express an opinion on the reserves data based
         on our evaluation.

         We carried out our evaluation in accordance with standards set out in
         the Canadian Oil and Gas Evaluation Handbook (the "COGE HANDBOOK")
         prepared jointly by the Society of Petroleum Evaluation Engineers
         (Calgary Chapter) and the Canadian Institute of Mining, Metallurgy &
         Petroleum (Petroleum Society).

3.       Those standards require that we plan and perform an evaluation to
         obtain reasonable assurance as to whether the reserves data are free of
         material misstatement. An evaluation also includes assessing whether
         the reserves data are in accordance with principles and definitions
         presented in the COGE Handbook.

4.       The following table sets forth the estimated future net revenue (before
         deduction of income taxes) attributed to proved plus probable reserves,
         estimated using forecast prices and costs and calculated using a
         discount rate of 10 percent, included in the reserves data of the
         Company evaluated by us for the year ended December 31, 2004 and
         identifies the respective portions thereof that we have audited,
         evaluated and reviewed and reported on to the Company's Board of
         Directors:

5.       In our opinion, the reserves data respectively evaluated by us have, in
         all material respects, been determined and are in accordance with the
         COGE Handbook. We express no opinion on the reserves data that we
         reviewed but did not audit or evaluate.

6.       We have no responsibility to update our reports referred to in
         paragraph 4 for events and circumstances occurring after their
         respective preparation dates.

         events, actual results will vary and the variations may be material.

                CHARTER OF THE AUDIT, FINANCE AND RISK COMMITTEE


MANDATE OF THE COMMITTEE
------------------------

The mandate of the Audit, Finance and Risk Committee (the "COMMITTEE") of the
Board of Directors (the "BOARD") of Compton Petroleum Corporation (the
"COMPANY") is to oversee that management has applied due diligence in creating
and maintaining an effective risk management and control framework. This
framework should provide reasonable assurance that the financial, operational
and regulatory objectives of the Company are achieved and that the statutory
responsibilities of the Board are discharged. The Committee fulfils its role on
behalf of the Board, by overseeing:

1.       the integrity of the Company's financial statements, financial
         information and accounting, financial reporting (including MD&A, as
         hereinafter defined) and auditing processes;

2.       the external auditor's qualifications, independence and performance;

3.       the Company's compliance with legal and regulatory requirements; and

4.       risk management, management information systems, governmental
         legislation and external business of the Company.

While the Committee has the responsibilities and powers set forth in this
Charter, it is not the duty of the Committee to plan or conduct audits, to
determine that the Company's financial statements are complete, accurate and in
accordance with generally accepted accounting principles, or to certify the
Company's financial statements. Management is responsible for preparing the
Company's financial statements and the Company's external auditor is responsible
for auditing the annual financial statements and for reviewing the interim
financial statements. The Committee shall however assist the Board in overseeing
that Management and the external auditor fulfill their responsibilities in the
Company's financial reporting process.

It is not the duty of the Committee to conduct investigations to assure the
Company's compliance with laws, regulations, or the Company's Code of Business
Conduct and Ethics.

The Committee has the authority to obtain independent legal counsel and outside
accounting and other advisors as deemed appropriate to perform its duties and
responsibilities. The Company shall provide appropriate funding to compensate
the external auditor and any advisors that the Committee chooses to engage. The
Committee is authorized to communicate directly with the external auditor to
discuss and review specific issues as necessary.

The Committee will primarily fulfil its responsibilities by carrying out the
activities enumerated in the following sections of this Charter. The Committee
will report regularly to the Board regarding the execution of its duties and
responsibilities.

In fulfilling its mandate, the Committee shall:
