                    PROXY STATEMENT AND INFORMATION CIRCULAR

                          OPTIMA PETROLEUM CORPORATION
                           SUITE 600 - 595 HOWE STREET
                           VANCOUVER, BRITISH COLUMBIA
                                 CANADA V6C 2T5
                                TEL: 604-684-6886

           (all information as at May 7, 1998 unless otherwise noted)



                         PERSONS MAKING THE SOLICITATION

This Proxy Statement and Information Circular ("Proxy Statement") is furnished
in connection with the solicitation of proxies being made by Management and the
Board of Directors of OPTIMA PETROLEUM CORPORATION (the "Company" or "Optima")
for use at the Annual and Special Meeting of Shareholders (the "AGM" or
"Meeting") to be held on Thursday, June 11, 1998 at the time and place and for
the purposes set forth in the accompanying Notice of Annual and Special Meeting
of Shareholders. While it is expected that the solicitation will be made
primarily by mail, proxies may be solicited personally or by telephone by
directors, officers and employees of the Company.

All costs of this solicitation will be borne by the Company.

                      APPOINTMENT AND REVOCATION OF PROXIES

This Proxy Statement and the accompanying Proxy will first be mailed to
shareholders on or about May 8, 1998.

The individuals named in the accompanying Proxy are directors and/or officers of
the Company. A SHAREHOLDER WISHING TO APPOINT SOME OTHER PERSON (WHO NEED NOT BE
A SHAREHOLDER) TO REPRESENT HIM OR HER AT THE AGM HAS THE RIGHT TO DO SO, EITHER
BY INSERTING SUCH PERSON'S NAME IN THE BLANK SPACE PROVIDED IN THE PROXY OR BY
COMPLETING ANOTHER PROXY. The Proxy will not be valid unless it is completed and
delivered to the Montreal Trust Company of Canada not less than 48 hours
(excluding Saturdays, Sundays and holidays) before the AGM at which the person
named therein purports to vote in respect thereof, or deposited with the Chair
of the Meeting on the day of the Meeting prior to its commencement.

A shareholder who has given a Proxy may revoke it by an instrument in writing
delivered either to the registered office of the Company at any time up to and
including the last business day preceding the day of the AGM or an adjournment
thereof, or to the Chair of the Meeting on the day of the AGM or an adjournment
thereof.

Revocation of a Proxy does not affect any matter on which a vote has been taken
before the revocation.

                             EXERCISE OF DISCRETION

The individuals named in the accompanying Proxy will, if the instructions are
certain, vote the shares represented thereby on any poll, and where a choice
with respect to any matter to be acted upon has been specified in the Proxy, the
shares will be voted in accordance with the specification so made. On a poll
<PAGE>   9
they will vote such shares for the approval of each matter disclosed in the
Proxy for which no specification has been made.

A properly executed proxy marked "ABSTAIN", although counted for purposes of
determining whether there is a quorum and for purposes of determining the
aggregate voting power and number of shares represented and entitled to vote at
the Meeting, will not be voted. Accordingly, abstentions will have the same
effect as a vote against the proposal. Shares represented by "broker non-votes"
(i.e., shares held by brokers or nominees which are represented at a meeting but
with respect to which the broker or nominee is not empowered to vote on a
particular proposal) will be counted for purposes of determining the aggregate
voting power and number of shares represented at the Meeting but will
disregarded in the calculation of a plurality or of "votes cast". Accordingly,
"broker non-votes" will have no effect on the proposal as to which the broker
has no authority to vote.

The enclosed Proxy confers discretionary authority upon the person appointed
proxy thereunder with respect to amendments or variations of matters identified
in the Notice of Annual and Special Meeting of Shareholders and with respect to
other matters which may properly come before the AGM. At the time of printing of
this Proxy Statement, Management of the Company knows of no such amendment,
variation or other matter to come before the AGM.

          VOTING SECURITIES AND PRINCIPAL HOLDERS OF VOTING SECURITIES

As of May 7, 1998, the Company had outstanding 11,002,346 fully paid and
non-assessable common shares without par value, each share carrying the right to
one vote.

Only shareholders of record at the close of business on May 7, 1998 will be
entitled to receive the Notice of Annual and Special Meeting of Shareholders and
to vote or to have their shares voted at the AGM.

The following table sets forth the beneficial ownership of common shares of the
Company as at May 7, 1998 of each person (including any group as that term is
used in section 13(d)(3) of the U.S. Securities Exchange Act of 1934, as
amended) known by the Company to be the beneficial owner of more than five
percent of the common shares of the Company, of each Director or nominee who
owns any such shares, of each Named Executive Officer (as defined below) and of
all officers and directors of the Company as a group:

         December 31, 1997 (ie. fiscal year end) was $1.50.

LONG-TERM INCENTIVE PLANS - AWARDS IN MOST RECENTLY COMPLETED FISCAL YEAR

The Company does not have a Long-Term Incentive Plan in place and therefore
there were no awards made under any long-term plan to the Named Executive
Officers during the Company's most recently completed fiscal year. A "Long-Term
Incentive Plan" is a plan under which awards are based on performance over a
period longer than one fiscal year, other than a plan for options, SARs (stock
option appreciation rights) or restricted share compensation.

DEFINED BENEFIT OR ACTUARIAL PLAN DISCLOSURE

The Company has no defined benefit or actuarial plan, under which benefits are
determined by final compensation of years of services for the Company's officers
and key employees.

COMPENSATION OF DIRECTORS

Directors who are Named Executive Officers are compensated as disclosed above in
their capacities as executive officers; they receive no compensation for acting
as directors.

Directors who are not executive officers of the Company are entitled a fee of
$500 for each meeting of the Board of Directors attended. Payment is made in the
form of 138 shares at a deemed price of $3.63 per share. Additionally,
non-executive officers and Directors were granted incentive stock options to
purchase an aggregate of 50,000 common shares.

During the Company's most recently completed fiscal year, the following
incentive stock options were granted to the Company's Directors, other than the
Named Executive Officers:

EMPLOYMENT CONTRACTS, TERMINATION OF EMPLOYMENT AND CHANGE IN CONTROL
ARRANGEMENTS

The Company has no employment contracts with the Named Executive Officers,
however, it has entered into consulting agreements which include termination
provisions. Refer to "Management Contracts" for further particulars.

REPORT ON REPRICING OF OPTIONS/SARS

The Company has not, since October 31, 1993 and during the most recently
completed financial year, repriced downward any options or SARs held by the
Named Executive Officers.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

Robert L. Hodgkinson, Emile D. Stehelin and Martin G. Abbott were members of the
Compensation Committee in 1997. Mr. Hodgkinson is the Chair of the Committee. He
has served as the Company's Chief Executive Officer since 1989.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

The Compensation Committee is responsible for reviewing the Company's
compensation policies and practices and making recommendations to the Board with
respect to compensation matters. It has no formal compensation policy. However,
executive officers are compensated in a manner consistent with their respective
contributions to the overall benefit of the Company.

Executive compensation is based on a combination of factors, including a
comparative review of information provided to the Compensation Committee by
compensation consultants, recruitment agencies, and auditors, as well as
historical precedent.

The Company's executive compensation is based upon the recognition that the
Company is a young, growing company which is best served by executives who are
prepared to accept lower levels of cash compensation in return for the
potentially greater rewards which may become available if the Company proves
successful. Therefore, the compensation programs are strongly oriented towards
long-term incentives which are designed to provide the Company's executives with
substantial rewards based upon the Company's long-term success. This approach
has the further benefit of aligning the interests of the Company's executives
with those of its shareholders.

With these principles in mind, the Compensation Committee has set forth the
following guidelines:

1.       Provide a total compensation package that will attract talented
         individuals to the Company and provide them with motivation to excel in
         their performance with a view to building long-term shareholder value;

2.       limit cash compensation to amounts which are reasonable but moderate in
         view of the Company's current stage of growth; and

3.       provide substantial long-term incentive benefits which will reward
         long-term commitment to the Company.

The Company currently pays each of its Named Executive Officers annual
consulting fees pursuant to consulting agreements. Refer to "Management
Contracts" for further particulars. Fees are fixed by the 


                                       -6-
<PAGE>   14
Board of Directors after consultation with the Compensation Committee. Fee
levels are reviewed at least annually and more often when circumstances warrant.

Stock options are granted to executive officers and other key employees whose
contributions are considered important to the long-term success of the Company.
Stock options have historically been granted by the Board of Directors on a
case-by-case basis based upon the Board's evaluation of an individual's past and
potential future contributions to the Company. Stock options are used to attract
new management personnel to the Company. In granting stock options, the Board of
Directors take into consideration the fact that compensation paid to its
executive officers and key employees may tend to be below industry averages. No
stock options were granted to executive officers in 1997.

The Compensation Committee is prepared to consider a compensation component
which is performance related. There was no compensation based on performance
paid during the most recently completed fiscal year.

Officers):

1.       Pursuant to a consulting agreement dated February 1, 1996 (the
         "Agreement"), $12,500 per month was paid to Hodgkinson Equities

                  STATEMENT OF CORPORATE GOVERNANCE PRACTICES

to provide guidance to the Company's management in the following areas:

         -        long term strategic planning

         -        risk analysis and monitoring of risk management systems

                                      -13-
<PAGE>   21
         -        overseeing the appointment and training of senior management
                  and monitoring their performance, including succession
                  planning

         -        establishing and monitoring the Company's communications
                  policy as implemented by the Company's investor relations

                  concerns of shareholders in particular

         -        ensuring the integrity of the Company's systems for internal
                  controls and management information

         -        develop the description for the Board and the CEO, including
                  the corporate objectives to be met by the CEO

The Board is aware of the expectations of The Toronto Stock Exchange ("TSE")
regarding corporate governance and it conducts itself, to the best of its
ability, in a manner consistent with those expectations.

COMPOSITION OF THE BOARD

The Company's Board presently consists of five Directors. Two members of the
Board are outside Directors who are not members of Management. All of these
outside Directors, representing a minority of the Board, can be considered
"unrelated" directors in that they do not have any interest or business or other
relationship which could or could reasonably be perceived to materially
interfere with their ability to act with a view to the best interests of the
Company. The Company does not have a significant shareholder who is able to
elect a majority of the Company's Board.

The Company does not have the recommended majority of its Board comprised of
unrelated directors. The Board believes that the extra cost of additional
unrelated directors is not presently warranted by the Company's size, although
this matter will be kept under review in light of future developments.

COMMITTEES

The Board presently has three committees to which it has assigned specific
responsibilities.

AUDIT COMMITTEE

The Audit Committee consists of three Directors, two of whom are outside
Directors and all of whom are unrelated directors. It carries out the following
responsibilities:

         *        reviewing the Company's audited financial statements

         *        meeting with the Company's management and auditors for that
                  purpose

         *        oversight responsibility for management reporting on internal
                  control

During the 1997 fiscal year, the Audit Committee held one meeting.



                                      -14-
<PAGE>   22
COMPENSATION COMMITTEE

The Compensation Committee presently consists of three Directors, two of whom
are outside Directors and all of whom are unrelated Directors. It carries out
the following responsibilities:

         *        considering and approving compensation of management and of
                  the Board and ensuring that it is commensurate with the level
                  of responsibility and risk involved

THE MERGER TRANSACTION

DESCRIPTION OF THE MERGER TRANSACTION

Optima and its Nevada subsidiary, Optima Energy (U.S.) Corporation ("Optima US")
have entered into a transaction whereby Optima US will acquire the entities that
own all of the shares of American Explorer, L.L.C. ("Amex") in exchange for the
issuance of Optima shares and rights to receive additional Optima shares (the
"Merger Transaction"). As part of this Merger Transaction, Optima US will
reincorporate as a Louisiana corporation and merge with the Target Corporations,
Optima will continue as a Delaware corporation and Amex will remain a wholly
owned Louisiana subsidiary of Optima US.

PURPOSE OF THE MERGER TRANSACTION

The purpose of the Merger Transaction is to combine the management and assets of
Optima and Amex. Optima and Amex have property interests in common (see
Valentine Prospect and Turtle Bayou prospects under "Information Concerning the
Company - Principal Producing Properties" and "Information concerning Amex and
the Target Corporation - Principal Producing Properties"). American Explorer,
Inc., a company owned by Charles T. Goodson and Alfred J. Thomas, II, is
operator of both prospects. As such, Optima Management has had the opportunity
to work with these individuals over a period of seven years and feel that they
will bring valuable industry experience to Optima's Board and Management.

THE PLAN AND AGREEMENT OF MERGER

Pursuant to a plan and agreement of merger (the "Merger Agreement") dated as of
February 11, 1998, Optima and Optima US agreed that Optima US will acquire all
of the issued and outstanding shares and membership interests of three Louisiana
corporations (the "Target Corporations"), which in turn, hold all of the issued
and outstanding membership interests of Amex. As consideration for this
acquisition, Optima has agreed to issue the Target Corporations an aggregate of
7,335,001 Optima common shares (the "Shares") and rights ("Contingent Stock
Issue Rights") to receive, subject to certain conditions, an additional
1,667,001 Optima common shares ("Rights Shares"). As at the record date, the
Company has 11,002,346 shares issued and outstanding. After the issuances of the
Shares, the Company will have 18,337,347 shares outstanding, with the Shares
representing 40% of the then outstanding stock. Upon the issuance of all the
Rights Shares, the Company will have 20,004,348 shares outstanding and the
Shares and Rights Shares will represent 45% of the then outstanding shares.

The Contingent Stock Issue Rights provide for the issue of Rights Shares if at
anytime on or before three years from the date of issue of the Contingent Stock
Issue Rights, the Fair Market Value of Optima's common shares is at or above
US$5.00 per share for a period of 20 consecutive trading days. The Fair Market
Value of an Optima share means, on any trading day, the closing sale price for
an Optima share on such day on the NASDAQ National Market System, or if no such
sales occur, the average of the closing bid and ask prices on The Toronto Stock
Exchange, or if no such sales occur, the closing bid and ask prices as quoted on
NASDAQ, or if not quoted on NASDAQ, the average of the closing bid and ask
prices as quoted on any recognized stock exchange on which the Optima shares are
listed.

</TABLE>

Robert R. Brooksher, a proposed nominee for director, holds an option to acquire
up to a 5% ownership interest in Amex, which option, if not exercised prior to
the closing of the Merger Transaction, shall continue in up to 5% of the
aggregate Optima's common shares and contingent stock issue rights issued to the
stockholders and members of the Target Corporations as a result of the Merger
Transaction.

Each of the Target Corporations has granted a security interest in all of its
membership interests in Amex to Compass Bank to secure Amex's obligations under
its bank facility, which security interest is to be released on or prior to the
closing of the Merger Transaction.

RECOMMENDATION OF OPTIMA BOARD OF DIRECTORS

THE OPTIMA BOARD BELIEVES THAT THE MERGER TRANSACTION IS FAIR AND IN THE BEST
INTERESTS OF OPTIMA AND THE OPTIMA SHAREHOLDERS, HAS VOTED UNANIMOUSLY TO
APPROVE THE MERGER TRANSACTION AND RECOMMENDS THAT THE OPTIMA SHAREHOLDERS
APPROVE THE MERGER TRANSACTION.

In reaching its conclusion, the Optima Board reviewed presentations from and
discussed the terms and conditions of the transaction with Optima senior
management, representatives of its legal counsel and its auditors.

The Optima Board considered a number of factors, including:

- -        Fairness Opinion. R P & C International, Inc. ("RP&C") rendered an
         opinion to the Optima Board to the effect that the Merger Transactions
         is fair from a financial point of view to the Optima shareholders. See
         "Fairness Opinion" below for particulars of matters considered by RP&C
         in the course of its review. A copy of the written opinion to the
         Optima Board dated as of March 7, 1998 is attached as Appendix B to
         this Proxy Statement.

- -        Evaluations of Interested Parties. Beginning in September, 1997,
         Optima initiated discussions and negotiations with several industry
         participants to initiate a transaction to enhance shareholder value.
         During this process, certain of these participants evaluated Optima and
         the Merger Transaction compared favourably to all other proposals.

- -        Common Interests. The Merger Transaction will combine the working
         interests of Optima and Amex in Optima's key Louisiana prospects. The
         strategic and operational fit between the two companies is also
         excellent.



                                      -18-
<PAGE>   26
- -        Complementary Reserves. Optima's reserves are primarily oil and are
         short-lived while Amex's are primarily gas and long-lived.

- -        Complementary Objectives. Optima is primarily a participant in
         prospects generated by others, while American Explorer, Inc. is a
         prospect generator. Upon completion of the Merger, Amex will become the
         prospect generating entity and American Explorer, Inc. will become
         inactive.

- -        Amex Management. Amex's senior management, led by Charles Goodson, has
         a proven track record in the U.S. oil and gas industry. Given Optima's
         U.S. asset base, U.S. based management is a logical progression for
         Optima.

FAIRNESS OPINION

RP&C International, Inc. has rendered to the Optima Board its opinion to the
effect that, as of the date of such opinion, based on RP&C's review and subject
to the considerations and limitations set forth insuch opinion, the
consideration to be paid pursuant to the terms and subject to the conditions set
forth in the Plan and Agreement of Merger, dated February 11, 1998 by and among
Optima Petroleum Corporation, Optima Energy (U.S.) Corporation and Goodson
Exploration Company, NAB Financial, L.L.C., Dexco Energy, Inc. and American
Explorer, L.L.C. was fair from a financial point of view to the holders of
Optima common stock. A copy of the full text of the written opinion of RP&C,
which sets forth the assumptions made, the procedures followed, matters
considered and limits of its review, is attached in Appendix B to this Proxy
Statement and should be read carefully in its entirety. The opinion of RP&C is
addressed to the Board of Optima and addresses only the fairness of the Merger
Transaction from a financial point of view of the Merger consideration to the
holders of Optima common stock and does not constitute a recommendation to any
holder as to how such holder should vote on this matter.

INTEREST OF INSIDERS IN THE MERGER

American Explorer, Inc., a corporation owned by Charles T. Goodson and Alfred J.
Thomas, II, owns 30,000 Optima common shares which were issued to it in 1995 in
consideration for facilitating Optima's acquisition of additional working
interests in the prospects operated by American Explorer, Inc. Mr. Robert
Brooksher owns 11,600 shares of Optima and holds an option to purchase up to a
5% ownership interest in Amex and Messrs. Goodson and Thomas are principals of
two of the Target Corporations. American Explorer, Inc. is not a party to the
Merger Transaction.

Pursuant to the Merger Agreement, Optima has agreed to put forward five
appointees of Amex as nominees for the Optima Board to be elected at the meeting
of Optima shareholders.

Pursuant to the Merger Agreement, Optima has agreed to enter into an agreement
to purchase a 5% working interest in the Valentine Prospect from certain Optima
insiders. As required by The Toronto Stock Exchange, Optima is seeking approval
of a majority of disinterested Optima shareholders to this acquisition. See
"Acquisition of 5% working interest in the Valentine Prospect".

Pursuant to the Merger Agreement, Optima will be entering into certain
severance, release and consulting agreements with the three executive officers
of Optima and employment agreements with four executive officers of Amex, which
provide for a payment in the event that an officer's employment is terminated by
Optima at any time other than for just cause.

Pursuant to the Merger Agreement, Optima has agreed to grant incentive stock
options to certain directors, officers and employees of Optima and Amex,
pursuant to a new Stock Option Plan to be approved by Optima shareholders.

<PAGE>   27
OPTIMA LOAN TO AMEX

On February 25, 1998, Optima US entered into a loan agreement with Amex that
provides for loan advances to Amex not to exceed US$2,500,000 in the aggregate,
to be advanced in amounts not to exceed US$500,000, and to be used by Amex
solely to finance its participation in an offshore exploration program. A total
of US$          [US$600,000 to date] has been advanced to Amex to date. The loan
agreement provides for the granting of security to Optima over Amex's Louisiana
and Texas properties, subordinate only to a first charge on these properties
held by Compass Bank. All advances under the loan agreement are repayable in
full on March 1, 1999 and bear interest at a rate of ten percent per annum.
Accrued interest is payable on the first business day of the next month, with
the first interest payment due on June 1, 1998. In the event of termination of
the Merger Agreement, the advances shall thereafter bear interest at a rate of
16% per annum.

ACCOUNTING TREATMENT

The Merger Transaction will be accounted for as a purchase of Amex by Optima for
Canadian GAAP (generally accepted accounting principles) purposes. For
presentation of certain anticipated effects on the accounting treatment on the
combined financial position and results of operation of Optima after giving
effect to the purchase of Amex by Optima, see the audited pro forma financials
statements attached as Appendix D to this Proxy Statement.

CONDUCT OF MEETING AND SHAREHOLDER APPROVAL

The meeting is being held on June 11, 1998 at the office of Campney & Murphy,
2100 - 1111 West Georgia Street, Vancouver, British Columbia.

The TSE requires, as a condition of its acceptance of the issuance of the
consideration by Optima pursuant to the Merger Transaction, "disinterested
shareholder approval", meaning a majority of the votes cast at the shareholders'
meeting other than votes attaching to the securities beneficially owned by
Robert Brooksher, Charles T. Goodson, Alfred J. Thomas, II and by their
associates and affiliates. As at the record date, Robert Brooksher, Charles T.
Goodson, Alfred J. Thomas, II and their associates and affiliates beneficially
own 41,600 common shares of the Company. The text of this resolution is set out
under "The Merger Transaction - Shareholder Approval." MANAGEMENT WILL BE ASKING
FOR DISINTERESTED SHAREHOLDERS' APPROVAL OF THE ISSUANCE OF THE CONSIDERATION BY
OPTIMA PURSUANT TO THE MERGER TRANSACTION ONLY IF THE CONTINUATION RESOLUTION IS
APPROVED (SEE "CONTINUATION INTO THE STATE OF DELAWARE").

Pursuant to the Merger Agreement, Optima has agreed to continue from the
jurisdiction of the Canada Business Corporations Act to Delaware and the
Delaware General Corporation Law. This continuation must be approved by a
special resolution, which requires the vote of not less than 66 2/3% of the
votes cast by those Optima shareholders who, being entitled to do so, vote in
person or by proxy at the meeting. The text of this resolution is set out under
"Continuation Into the State of Delaware - The Continuation Resolution".

Pursuant to the Merger Agreement, Optima has also agreed to enter into an
agreement to acquire a 5% working interest in the Valentine Prospect for certain
insiders of Optima. This agreement must be approved by a majority of
disinterested shareholders. The text of this resolution is set out under
"Acquisition of 5% Working Interest in the Valentine Prospect - Shareholder
Approval".

independent engineers. Arenosa was subsequently wound up after transferring all
of its assets to Optima US.

Optima participates as a working interest holder in numerous oil and gas
prospects which are operated by third parties. By funding its proportionate
share of drilling costs of a successfully completed well, Optima earns an
interest in the well and in the related acreage, based on the terms of the
applicable participation agreement.

TURTLE BAYOU/KENT BAYOU PROPERTY, LOUISIANA

Gross daily field production for the month of February, 1998 averaged 7,764 MCF
of natural gas and 188 barrels of condensate per day. The Company's working
interest varies between 13.475% and 24.25% with a weighted average of barrels on
proven reserves of 13.9%. The field operator is American Explorer, Inc.
Currently, there are 5 producing wells in these fields. During December, 1997
and January, 1998 a recompletion program was undertaken on 4 wells. This program
resulted in production from previously non-producing formations in the well
bore.

A 3-D regional seismic survey is currently being shot which incorporates the
Turtle Bayou field. The operator, American Explorer, Inc. has negotiated access
to the data set which should be available later in 1998. Any further exploration
will be contingent on the interpretation of this data set identifying new deep
drilling targets

A number of voluntary production units were established with the Department of
Conservation State of Louisiana in February, 1997 and accordingly, Optima's
current leased acreage position is 2,251 gross acres.

Amex also holds a weighted average working interest of 8.5% in this prospect
(see "Information Concerning Amex and Target Corporation - Principal Producing
Properties"). After giving effect to the Merger Transaction, Optima's combined
interests will vary between 32.1% and 11.9% with a weighted average working
interest of 24%.

VALENTINE PROSPECT, LOUISIANA

The Company owns a 35% working interest (at an average 82.5% net revenue
interest) in 24 wells, of which 4 are producing at an average daily rate of 698
MCF and 149 barrels of oil. As at December 31, 



                                      -24-
<PAGE>   32
1997, Optima's gross acreage position on the prospect was 29,317 gross acres,
including 18,742 acres held under option.

As a condition to an acquisition of additional working and net revenue interests
in 1997, Optima US, along with the other working interest holders (including
Amex) was required to fund from production its pro rata share of a US$1.4
million escrow account. The proceeds from this account will be utilized for
wellsite restoration. This escrow account was fully funded as at January 31,
1997.

In 1997, a major oil and gas company entered into an agreement with Optima US
and the other working interest holders to fund a US$10 million seismic program
to identify deeper drilling targets on the Valentine salt dome. For further
particulars of this program, which requires Optima and Amex to assign 50% of
their respective working interests in the 100 square mile program over to such
oil and gas company, see "Information concerning Amex and the Target Corporation
- - Principal Producing Properties - Valentine Field, Lafourche Parish, LA".

Management is seeking disinterested shareholders' approval for the acquisition
of a further 5% working interest in the Valentine prospect, which if completed,
will increase Optima US's interests to a 40% working interest.
See "Acquisition of 5% Working Interest in the Valentine Prospect".

Amex also holds a working interest of 47.5% in this prospect (See "Information
Concerning Amex Principal Producing Properties"). After giving effect to the
Merger Transaction and the 5% acquisition discussed above, Optima US's combined
interests will result in an 87.5% working interest in the existing producing
properties.

TEXAS MERIDIAN JOINT VENTURE, LOUISIANA

Pursuant to the master participation agreement with Meridian Resource
Corporation ("TMR") dated October 1, 1993, Optima US has evaluated ten prospect
areas of which five have been drilled, four rejected pursuant to the geological
and geophysical review and one prospect at Stella is to be drilled during 1998.
Seven features have been evaluated by drilling resulting in five gas wells, four
oil wells and five dry holes.

OTHER PROPERTIES

Optima US acquired a 25% working interest in the Chrysler prospect in Lea
County, New Mexico. The target is the Devonian formation and is supported by
interpreted 3-D seismic. The first well, Savage #34-1 was spudded in December,
1996, drilled to 13,000 feet and abandoned on February 17, 1997. A second well
is scheduled to be drilled in 1998. During 1996 two more wells were drilled to
the Smackover "C" sands at East Haynesville. Both wells the Garrett #1 and
Delaney #1 are producing in the Smackover "C". Further development will occur in
this field once the Commissioner of Conservation, State of Louisiana assigns 320
acre production units in both the Smackover Lime and "C" formations. A hearing
is scheduled in mid-April, 1998. The Company holds a 28% working interest at
East Haynesville.

After the sale of substantially all of its Canadian properties in June, 1997,
Optima retains a 77% working interest in a shut-in well located at 05-10-58-23
W5M in Wildhay, Alberta. This well is the subject of litigation between Optima,
Dunhaven Energy Inc. (a co-participant), Artisan Corporation (the drilling
contractor) and TuboscopeVetco Canada Inc. (the drillpipe supplier). For further
information, see "Information concerning the Company - Legal Proceedings".

A report dated March 12, 1998 prepared by LaRoche Petroleum Consultants, Ltd.
values the U.S. lands (other than the Stella Prospect, Louisiana) at
US$3,855,311. The Stella Prospect has been valued at cost (US$231,859) for a
total value of US$4,087,170 or $5,846,000.

RESERVES

Substantially all of Optima's oil and gas reserves are located in Louisiana.
LaRoche Petroleum Consultants, Ltd. ("LaRoche") and Ryder Scott Company ("RS"),
both independent reservoir engineers, have evaluated Optima's reserves (the
"LaRoche Report" and the "RS Report") effective December 31, 1997. The crude oil
and natural gas reserves and revenues estimates upon which this evaluation is
based were determined in accordance with generally accepted evaluation
practices.

The following table summarizes LaRoche's and RS's evaluations. ALL EVALUATIONS
OF FUTURE NET PRODUCTION REVENUE SET FORTH IN THE TABLES ARE STATED PRIOR TO
PROVISIONS FOR INCOME TAXES AND INDIRECT COSTS. IT SHOULD NOT BE ASSUMED THAT
THE DISCOUNTED FUTURE NET REVENUES SHOWN BELOW ARE REPRESENTATIVE OF THE FAIR
MARKET VALUE OF OPTIMA'S RESERVES. Other assumptions and qualifications relating
to costs, prices for future production and other matters are included in the
LaRoche Report and the RS Report. The LaRoche Report evaluates those prospects
operated by American Explorer, Inc. and the RS Report evaluates those prospects
operated by TMR.

(1)      "Proved Reserves" are defined as those quantities of crude oil, natural
         gas and natural gas by-products, which, upon analysis of drilling,
         geological, geophysical and engineering data, are estimated to be
         recoverable under current technology and existing economic conditions
         from that portion of a reservoir which can be reasonably evaluated as
         economically productive, including reserves obtainable by enhanced
         recovery procedures demonstrated to be economic and technically
         successful in the subject reservoir. There is relatively little
         engineering and geological risk associated with these reserves.

(2)      "Proved Producing Reserves" are those proved reserves that are actually
         on production or if not producing, that could be recovered from
         existing wells or facilities or where the reasons for the current
         non-producing status is the choice of the owner rather than the lack of
         markets or some other reason. "Proved Undeveloped Reserves" are
         reserves that have been drilled and casing run through the zone. A
         workover may be required to place these reserves on producing status.
         "Proved Non-Producing Reserves" are proved reserves that are currently
         not producing either due to lack of facilities and/or markets.

(3)      "Probable Additional Reserves" are those reserves which analysis of
         drilling, geological, geophysical and engineering data does not
         demonstrate to be proved under current technology and existing economic
         conditions, but where such analysis suggest the likelihood of their
         existence and future recovery. Probable Additional Reserves to be
         obtained by the application of enhanced recovery processes will be in
         the increased recovery over and above that estimated in the proved
         category. THERE IS SOME DEGREE OF GEOLOGICAL AND ENGINEERING RISK
         ASSOCIATED WITH PROBABLE RESERVES. ADJUSTMENTS WERE MADE TO THE FUTURE
         NET PRODUCTION REVENUE FROM PROBABLE RESERVES TO ACCOUNT FOR THE
         GEOLOGICAL AND ENGINEERING RISK ASSOCIATED WITH THESE RESERVES. The
         risk associated with the probability of obtaining production from
         probable reserves has been assessed at 50%.

(4)      Constant pricing in US dollars on a property by property basis,
         adjusted for quality, transportation and heating value where necessary,
         have been used in the LaRoche and RS Reports. Base produce prices used
         for Louisiana (varying by field) were $2.43/mcf for gas and $17.28/BBL
         for oil in the LaRoche Report and $2.27 - $2.43/mcf gas and $17.53 -
         $17.78/BBL oil with the RS Report.

(5)      Abandonment and reclamation costs and salvage credits have not been
         considered in the valuation of reserves.

(6)      Current operating costs were held constant throughout the life of the
         properties. No deduction was made for indirect costs which were not
         charged directly to the leases and wells.

NOTES:

1.       "Gross Wells" refers to all wells in which Optima participated.

2.       "New Wells" refers to the aggregate of the percentage working interest
         of Optima in Gross Wells.

3.       "Dry Wells" refers to a well which is not a productive well or a
         service well. A productive well is a well which is capable of producing
         oil or gas in commercial quantities considered by the operator to be
         sufficient to justify the costs required to complete, equip and produce
         the well. A service well refers to a well such as a water or gas
         injection or water-disposal well. Such wells do not have marketable
         reserves of crude oil or natural gas attributed to them but are
         essential to the production of the crude oil and natural gas reserves.

VARIATIONS IN OPERATING RESULTS

The following is a summary of the variations in Optima's operating results for
the periods indicated.

TWELVE MONTHS ENDED DECEMBER 31, 1997 TO TWELVE MONTHS ENDED DECEMBER 31, 1996

The Company reported a loss for the year of $4,835,220 being $0.43 per share as
compared to earnings of $228,573 in 1996 of $0.02 per share. The decline of
$5,063,793 is due to a combination of production volume decline, a $2,252,000
ceiling test writedown of U.S. resources properties and a $1,023,998 provision
for revenue dispute. The 70% reduction in natural gas volume from 3,309,000 mcf
in 1996 to 



                                      -29-
<PAGE>   37
1,003,147 mcf is primarily due to the sale of Canadian petroleum and natural gas
assets effective January 1, 1997. Canadian operations represented between 55% to
60% total entity production over the previous 12 to 18 months. Although oil
production was also impacted by the Canadian asset sale, new production at Back
Ridge, Louisiana resulted in only an 8% decline in production volume. Oil prices
declined slightly by 6% whereas natural gas prices were 48% higher than 1996.

Earnings before interest, depletion, depreciation, amortization and income taxes
("EBITDA") decreased to $2,358,229 or $0.21 per share as compared to $6,662,544
in 1996 or $0.61 per share. The weighted average number of shares used in the
calculation of earnings for the year and for EBITDA was 11,159,633 shares
whereas the 1996 calculations are based on 10,945,927 shares. The number of
issued and outstanding shares was 11,318,894 as at January 1, 1997 but due to
share repurchase program was reduced to 11,002,346 shares at December 31, 1997.

Operating Expense. Oil and natural gas operating expenses decreased from
$1,649,650 in 1996 to $1,018,211 in 1997. On a boe basis, operating expenses
increased to $3.29 as compared to $2.34 in 1996. The increase is due to
workovers at Valentine and declining gas productivity at Lake Boeuf.

Interest and Other Income. Interest revenue of $250,916 in 1997 as compared to
$26,095 a year earlier reflects the significant improvement in the Company's
cash position resulting from the sale of Canadian assets.

Interest Expense. Proceeds from the sale of Canadian assets were utilized to pay
off the Canadian bank loan. Additionally the Company reduced its U.S. bank loan
to US$100,000. As a result the interest and bank charges fell to $188,468 in
1997 as compared to $685,942 a year earlier.

Depletion, Depreciation and Amortization. Depletion and depreciation decreased
to $4,269,785 in 1997 from $5,661,205 in 1996 or 25%. On a boe basis in 1997,
the expense was $13.62 per boe versus $8.03 per boe in 1996 (this comparison is
based on an energy equivalent of 6mcf per boe). The calculation of depletion and
depreciation is based on the Evaluation Reports as at December 31, 1997 prepared
by the independent engineering consultants. These reports assume unescalated
pricing and do not recognize the results of subsequent drilling and completion
activity after December 31, 1997.

The amortization expense of $68,494 did not change from 1996 as deferred charges
are being amortized over 60 months.

General and Administrative Expense. General and administrative expense of
$1,691,779 in 1997 is an increase of $28,368 over 1996, a change of 2%. On a boe
basis, general and administrative expenses were $5.40 per boe, up 129% from
$2.36 per boe in 1996 to reflect the decline in the 1997 production, as
discussed above.

Investment Carrying Value. Pursuant to both Canadian and United States full cost
method of accounting the Company is required to meet certain ceiling tests in
respect of the carrying value of petroleum and natural gas interests on the
balance sheet as at December 31, 1997. A ceiling test writedown of $2,520,000 of
petroleum natural gas interest was reflected in the Consolidated Statement of
Operations and Deficit.

Balance Sheet. The Company's total assets as at December 31, 1997 were
$28,143,343 as compared to $41,214,668 a year earlier. The decline of 32% over
the past year is due to the combination of the sale of Canadian assets and
paydown of Canadian and U.S. bank loans.



                                      -30-
<PAGE>   38
Petroleum and natural gas interests were reduced to $17,695,968 (being
$34,691,297 less $16,995,329) from $34,764,350 a year earlier. Canadian
petroleum and natural gas interests are $1,211,921 as at December 31, 1997 as
compared to $16,848,304 last year whereas U.S. petroleum and natural gas
interests declined by $1,431,999 from $17,916,046 as at December 31, 1996 to
$16,484,047 at the end of the current year.

In respect of liabilities and shareholders' equity, long term debt declined to
$143,050 from $6,119,670 being 98%. Shareholders' equity at December 31, 1997
decreased to $25,738,200 from $31,472,428 at the end of 1996. The decline of
$5,734,226 being 18% is a result of the net loss of $4,835,220 along with the
repurchase of common shares.

YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995

The Company realized earnings for the year of $228,573 being $0.02 per share as
compared to a loss in 1995 of $1,155,062 or $0.13 per share. This improvement of
$1,384,235 is a result of increased oil and gas production and improved
commodity prices. Gross natural volumes increased 40% from 2,364,489 mcf to
3,309,438 mcf. The increase in oil production was 116% from 71,122 barrels to
153,699 barrels. Combined with strong oil prices, this improvement resulted in
gross oil revenue increasing by 165% from $1,719,186 in 1995 to $4,549,235 in
1996. The combined oil and gas revenue for 1996 was $12,862,701 as compared to
$6,762,407 in 1995.

Earnings before interest, depletion, depreciation, amortization and income taxes
("EBITDA") increased to $6,662,544 or $0.61 per share as compared to $2,481,057
in 1995 or $0.27 per share. The weighted average number of shares used in the
calculation of earnings for the year and for EBITDA was 10,945,927 shares
whereas the 1995 calculations are based on 9,031,583 shares. The primary reason
for this difference is the 1,374,227 shares from the plan of arrangement with
Roxbury Capital Corp. ("Roxbury") which were issued in September, 1995 and
shares issued from treasury in 1996.

Operating Expense. Oil and natural gas operating expenses increased from
$926,159 in 1995 to $1,649,650 in 1996. On a boe basis, operating expenses fell
to $2.34 in 1996 from $3.03 in 1995, an improvement of 23%. Canadian operating
costs fell from $3.49 per boe in 1995 to $2.51 in 1996. Although operating
expenses in the U.S. varied slightly, $2.22 per boe in 1996 versus $2.34 per boe
in 1995, the 110% increase in Canadian gas production accounts for the
differential.

Interest and Other Income. Interest revenue of $26,096 in 1996 did not vary
significantly from $25,784 a year earlier. Short term Canadian interest rate
averaged between 3% and 4.5% over the year.

Interest Expense. Interest expense and bank charges were $685,942 in 1996, as
compared to $461,531 in 1995. The primary reason for this increase was that the
combined bank loan and debenture principal balance for 1996 averaged $7.5
million Canadian, whereas in 1995 the average principal balance was below $5.0
million.

Depletion, Depreciation and Amortization. Depletion and depreciation increased
to $5,661,205 in 1996 from $3,207,118 in 1995, an increase of 77% on a boe basis
in 1996 expense was $8.03 per boe versus $6.84 in 1995, (this comparison is
based on an energy equivalent of 6 mcf per boe). The calculation of depletion
and depreciation is based on the Evaluation Reports as at December 31, 1996,
prepared by the independent engineering consultants. These reports assume
unescalated pricing and do not recognize the results of subsequent dividing and
completion after December 31, 1996.



                                      -31-
<PAGE>   39
The amortization expense of $68,494 is derived from the costs of the 1995
Roxbury plan of arrangement in 1996. These deferred charges are being amortized
on a straight line basis over 60 months from the date of acquisition.

General and Administrative Expense. General and administrative expense of
$1,663,411 in 1996 is an increase of $193,328 over 1995, a change of 13%. On a
boe basis, general and administrative expenses were $2.36 down 25% from $3.16
per boe in 1995.

Investment Carrying Value. Pursuant to both Canadian and United States full cost
method of accounting, the Company is required to meet certain ceiling tests in
respect of the carrying value of petroleum and natural gas interests on the
balance as at December 31, 1996. The Company met these ceiling tests, and
accordingly, no write-down of petroleum and natural gas interests was required.

Balance Sheet. The Company's total assets as at December 31, 1996 were
$41,214,688 as compared to $39,178,076 a year earlier. This increase of 5% over
the past year is due primarily to an improvement in working interest capital of
$541,651. Whereas the increase in petroleum and natural interests to $34,764,350
(being $50,376,801 of capital costs less $15,612,451 in accumulated
depreciation, depletion and write-offs) was only $1,264,670, a reduction in the
level of year end activity reduced the advances to operators by $881,352. The
note receivable at year end of $497,692 is in respect of the sale at Elm Grove
which closed in 1996. In respect of liabilities and shareholders' equity, long
term debt (including current portion) declined slightly to $6,850,017 from
$7,390,400 a year earlier. This change is a combination of higher bank debt and
the redemption of $829,000 of convertible debentures. Shareholders' equity at
December 31, 1996 increased to $31,472,428 from $28,477,535. This change is a
combination of $228,573 in income for the year end and the net issuance of Cdn
759,452 common shares for $2,766,320.

TWELVE MONTHS ENDED DECEMBER 31, 1995 TO DECEMBER 31, 1994

The Company realized a substantial increase in production as compared to 1994
which contributed to the increase in gross revenue and earnings before interest,
depletion, depreciation of taxes. Gross natural gas volumes increased 80% from
1,311,852 mcf to 2,364,489 mcf where oil production almost doubled to 71,122
barrels from 36,337. Based on a barrel of oil equivalent basis ("boe") of 10 to
1 (1 barrel equals 10 mcf) which in the Company's opinion reflects the
comparative financial value of oil and gas, production increased from 167,455
boe in 1994 to 307,571 in 1995, an increase of 82%. Gross revenue increased by
63% from $4,137,141 in 1994 to $6,762,407 in 1995. Whereas 75% of the Company's
production is in the form of natural gas, the 17% decline in the average gas
price resulted in the rate of increase in revenue to lag behind in the increase
in production.

Earnings before interest, depletion, depreciation and taxes in 1995 increased to
$2,481,057 from $1,358,079 in 1994, an increase of 83%. Loss per share in 1995
fell to $0.13 per share being $1,155,062 from $0.56 in 1994, an improvement of
77%. The weighted average number of shares used in the calculation was 9,031,583
shares in 1995 as compared to 7,625,417 shares in 1994 and reflects the issuance
of 1,374,727 shares from the Roxbury plan of arrangement.

Operating Expenses. Oil and natural gas operating expenses increased to $926,159
in 1995 from $615,477 in 1994. On a boe basis operating expense fell by 14% to
$3.03 per boe in 1995 from $3.68 per boe in 1994. This improvement results from
the benefit of economics of scale at Wildhay River and Lake Boeuf, where the
Company was realizing higher production levels.




                                      -32-
<PAGE>   40
Interest and Other Income. Interest revenue fell from $45,628 in 1994 to $25,784
reflecting lower short-term interest rates in Canada and a lower average cash
balance throughout 1995. Other income of $47,748 is a result of the conversion
of debentures received on the sale of debenture received on the sale of marginal
properties to SLN Ventures Corporation.

Interest Expense. Interest expense and bank charges increased to $461,351 in
1995 from $126,399 in 1994 as a direct result of an increase of $5,561,400 in
bank debt.

Depletion, Depreciation and Amortization. Depletion and depreciation increased
substantially from $1,719,897 in 1994 to $3,207,118 in 1995, an increase of 86%.
On a boe basis, the 1995 expense was $6.84 per boe versus $6.74 in 1994 (this
comparison is based on 6 mcf equal to 1 barrel which is the energy equivalent).
The calculation of depreciation and depletion is based on the Evaluation Reports
as at December 31, 1995 which assumes unescalated commodity pricing and does not
recognize the results of subsequent drilling and completion after December 31,
1995.

The amortization expense of $22,587 is derived from the costs of the plan of
arrangement with Roxbury Capital Corporation. These deferred charges are being
amortized on a straight line basis over 60 months from the date of acquisition.

General and Administrative Expense. General and administrative expense of
$1,470,083 in 1995 is an increase of $362,736 over 1994, a change of 33%. The
increase is due to a combination of consultants expense and office rent absorbed
in a plan of arrangement with Roxbury as well as on an increase in the level of
remuneration. General and administrative expense were $3.16 per boe in 1995 as
compared to $4.34 per boe in 1994.

Investment Carrying Value Adjustment. There was no write down of petroleum and
natural gas interests in 1995 as compared to $4,000,000 in 1994. The Company met
the ceiling tests under Canadian generally accepted accounting principles. Under
the United States full cost method of accounting for petroleum and natural gas
interests, the Company, using oil and gas prices at the balance sheet date,
would have been required to write down its Canadian petroleum and natural gas
interests by approximately $800,000.

Balance Sheet. Total assets as at December 31, 1995 were $39,178,076 as compared
to $24,794,082 a year earlier. The major source of the change is in petroleum
and natural gas interest of $33,499,680 (being $43,597,549 in capital costs less
$10,097,869 in accumulated depreciation, depletion and write-offs) which
increased $11,240,175 in 1995. During 1995 the Company participated in the
drilling of 11 gross wells (2.84 net wells). Additionally, the increase in
petroleum and natural gas interests reflects the acquisition of Roxbury and
additional interests in Turtle Bayou, Louisiana. In respect of the liabilities
and shareholders' equity, long term debt increased from $1,849,000 as at
December 31, 1994 to $7,390,400 as at December 31, 1995. Shareholders' equity as
at December 31, 1995 increased to $28,477,535 from $20,837,561. The major change
is due to the issuance of 2,137,340 shares for $8,795,036 in cash and assets
combined with the loss for the year of $1,155,062.

TWELVE MONTHS ENDED DECEMBER 31, 1994 TO TWELVE MONTHS ENDED DECEMBER 31, 1993

Net loss for the year ended December 31, 1994 was $4,305,090 as compared to a
loss of $260,732 for the previous year. The major reason for this difference is
a ceiling test write down of petroleum and natural gas interests of $4,000,000.



                                      -33-
<PAGE>   41
Loss per share for the year ended December 31, 1994 was $0.56 compared to a loss
of $0.05 for the 1993 fiscal year.

Optima reported petroleum and natural gas sales, after royalties and production
taxes, of $3,080,903 compared with $2,486,000 in 1993. Interest revenue was
$45,628 as compared to $107,975 for the previous year.

Depreciation and depletion expense was $1,719,897 for 1994 as compared to
$815,655 for the 1993 fiscal year. The increase in these non-cash expenses is
due to the combination of increased production and the 1995 capital expenditures
program which was focused on leasehold acquisition, seismic, geological and
geophysical expenditures; specifically significant land acquisition at Wildhay,
the Texas Meridian Joint Venture and the drilling of the Vermillion State Lease
#1-28 well.

LIQUIDITY AND CAPITAL RESOURCES

Twelve Months Ended December 31, 1997 to Twelve Months Ended December 31, 1996

Working capital as at December 31, 1997 was $7,856,820 as compared to $1,185,511
a year earlier. Cash and cash equivalents increased to $5,660,354 at year end
from $2,055,062 at December 31, 1996. In addition, a further $715,250 was held
in trust to fund future abandonment and site restoration work in the Valentine
field.

The increase in working capital of $6,671,609 over the fiscal year 1997 is a
result of a is primarily due to the sale of Canadian operations. Cash flow from
operations was $2,528,992 in 1997 as compared to $5,958,272 in 1996, a decline
of $3,429,280. After utilizing $1,807,809 of cash flow to reduce accounts
payable, and a further $440,586 consumed in the sale of the Canadian petroleum
and natural interests, the Company had $577,024 to finance its capital
expenditures. A year earlier discretionary cash flow was $5,348,360, which
represents a reduction of $4,771,336.

Net capital receipts for 1997 were $9,508,049 as compared to cash requirements
of $6,045,068 in 1996. Proceeds from sale of petroleum and natural interests net
petroleum and natural gas expenditures was $16,750,000 in 1996 as compared to
$1,176,849 a year earlier.

In respect of financial activities, the Company redeemed common shares in the
amount of $899,006 and reduced its bank debt by $6,707,567.

The Company as of the date of this Proxy Statement is not in a position to
forecast 1998 capital requirements. The Merger Transaction, if consummated, will
allow for a more precise determination of capital requirements.

RISKS AND UNCERTAINTIES

Optima operates a growing business in a competitive market. There are a number
of risks inherent to Optima's business. There is competition from other oil and
gas exploration and development companies with operations similar to those of
Optima. Many of the oil and gas companies with which Optima competes have
operations and financial strength many times that of Optima. Nevertheless, the
market for Optima's existing and/or possible future production of petroleum and
natural gas tends to be commodity oriented, rather than company oriented.
Accordingly, Optima expects to compete by keeping its production costs low
through judicious selection of which property to develop, the practice of joint
venturing its interests, and keeping overhead charges under control.



                                      -34-
<PAGE>   42
The business of exploration for and production of oil and gas involves a
substantial risk of investment loss. Drilling oil and gas wells involves the
risk that the wells will be unproductive or that, although productive, the wells
do not produce oil or gas in economic quantities. Other hazards, such as unusual
or unexpected geological formations, pressures, fires, blowouts, loss of
circulation of drilling fluids or other conditions may substantially delay or
prevent completion of any well. Adverse weather conditions can also hinder
drilling operations. A productive well may become uneconomic if water or other
deleterious substances are encountered, which impair or prevent the production
of oil or gas from the well. In addition, production from any well may be
unmarketable if it is impregnated with water or other deleterious substances.
The marketability of crude oil and natural gas is affected by numerous factors
beyond the control of Optima. These factors include market fluctuations, the
world price of crude oil, the proximity and capacity of crude oil and natural
gas pipelines and processing equipment and government regulations, including
regulations relating to prices, taxes, royalties, land tenures, allowable
production, the import and export of crude oil and natural gas and environmental
protection. The effect of these factors cannot be predicted.

As with any oil or gas property, there can be no assurance that oil or gas will
continue to be produced from Optima's properties. Although the operators of
Optima's properties maintain insurance in amounts customary in the industry for
liability and property damage on behalf of the working interest participants,
Optima may suffer losses from uninsurable hazards or from hazards which Optima
may choose not to insure against because of high premium costs or other reasons.

As is customary with working interests in U.S. oil and gas leases, the interests
acquired by Optima are generally assigned without warranty of title or title
insurance. In most cases, drill site opinions are obtained by operators prior to
drilling rather than formal title opinions. In addition, Optima's interests are
not actually transferred to it until the wells are drilled, or in certain
prospects, until the prospects are unitized.

DESCRIPTION OF SHARE CAPITAL

The authorized share capital of Optima consists of an unlimited number of shares
of common stock without par value of which 11,002,346 are outstanding as of
December 31, 1997.

The holders of common shares are entitled: (i) to receive notice of and to
attend and vote, with one vote for each common share held, at any meeting of the
shareholders of Optima other than meetings of holders of another class of
shares; (ii) subject to the rights attached to any other class of shares, to
receive any dividend declared by Optima on the common shares; and (iii) subject
to the rights attaching to any other class of shares, to receive the remaining
property of Optima upon dissolution.

LEGAL PROCEEDINGS

Except as disclosed below, there are no material legal proceedings to which
Optima or any of its subsidiaries is a party or to which any of their properties
is subject and no other material legal proceedings are known to be contemplated.

S.W. Holmwood

The Company is a party to litigation in the United States District Court,
Western District of Louisiana (Amoco Production Company vs. Texas Meridian
Resource Exploration, Inc.) by virtue of its master participation agreement with
Meridian Resource Corporation (formally known as Texas Meridian Resource
Corporation).

The litigation enures from a joint exploration agreement between the plaintiff
and defendant whereby adjoining petroleum and natural gas leases were pooled on
a 50%/50% joint ownership basis. Two producing oil wells have been drilled and
placed on production. The plaintiff is claiming a breach of trust and demands
surrender of 100% of the wells ownership on a retroactive basis and has received
a favourable summary judgement. The operator pending the court's granting of
damages intends to appeal the judgement.

The Company holds a beneficial 4% working interest. Since the outcome of this
litigation is not determinable, the Company has recorded 100% of the cumulative
net operating income to date aggregating to $1,023,000 as Revenue in Dispute.

Wildhay

The Company is party to a statement of claim and counterclaim with a drilling
contractor in the Judicial District of Calgary, Court of Queen's Bench, Alberta.
The nature of this litigation is based on a contract wherein the drilling
contractor drilled a well on behalf of the Company and a joint venture partner.
The working interest participants are demanding $2,738,568 in throw away costs
and expenses plus $1,001,755 for loss of the original well as well as $5,932,000
of reservoir damage from the drilling contractor. The well in question is
reflected in property and equipment at $1.1 million and an additional $1.2
million is included as a receivable from the Company's joint venture partner.

<PAGE>   46
Immediately prior to the completion of the Merger Transaction, the only assets
of Goodson, Dexco and NAB will be their respective membership interests in Amex.

Amex is an oil and gas exploration and production company. Its main focus is
exploration in the Gulf Coast region of Southern United States and offshore Gulf
of Mexico. It participates in the production of five fields, consisting in the
aggregate of 51 wells. For the month ended December 31, 1997, daily production
averages 7.6 MMCFGPD and 180 BOPD.

Amex has 25 full time employees and consultants, which include landmen (4),
geologists and geophysicists (6), petroleum engineers (3), accountants (4) and
support personnel along with 15 field personnel which work in the field
operations.

Future exploration emphasis will be primarily focused in two areas: the Onshore
Gulf Coast region and the State and Federal waters off the Louisiana and Texas
Coast.

Amex's main focus in exploration across all of the above areas will be to
generate or acquire and complement with added data, prospects that have low risk
developmental potential along with medium to high risk exploration potential.

Onshore, Amex's most successful efforts to date have been in existing fields
primarily developed by the major oil companies in the 1940's, 50's and early
60's which have exhibited steep declines in their production rates and thus
allow for farmouts or property purchases. In some cases companies have actually
allowed leases to expire, thus providing Amex the opportunity to acquire new
leases. With the advent of much improved 2-D and 3-D seismic data Amex is able
to focus on deeper objectives that remain virtually untested. As has been proven
out in the offshore, onshore 3-D will meet with states of exploration and
development success, i.e., first pass 3-D surveys will most certainly not always
correctly image all or in many cases most of the subsurface opportunities. Amex
will therefore continue to monitor the many onshore leads and opportunities that
it has developed.

In the offshore, Amex plans to focus only on areas where 3-D data is available
for future lease sales and existing leases that are available for farmout or
sale. In addition, Amex's area of interest is in the shallow to mid-depth water
where facility costs are reasonable and pipeline accessibility is readily
available, thus resulting in short term investments prior to realizing cash
flow.

PRINCIPAL PRODUCING PROPERTIES

SOUTH LOUISIANA AND ZONE 1

Turtle Bayou Field, Terrebonne Parish, LA

Amex has participated in the drilling of 10 wells in Turtle Bayou Field.
Currently, there are 5 producing wells in the field that Amex holds a working
interest. Collectively the 5 producing wells averaged 7764 MCF of natural gas
and 188 barrels of condensate per day for the month of February 1998. Amex's
working interest varies between 18.6% and 4.9% with a weighted average working
interest of 8.5%.

A 3-D regional seismic survey is currently being shot which incorporates the
Turtle Bayou Field. Amex has negotiated access to the data set which should be
available later this year. Any further exploration will be contingent on the
interpretation of this data set identifying new deep drilling targets. As of
February 28, 1998, Amex, as operator, has assembled a total of 2,251 gross acres
through farmout and lease acquisition in Turtle Bayou Field. For further
information on this property, see "Information Concerning the Company--Principal
Producing Properties".



                                      -39-
<PAGE>   47
Bully Camp Field, Lafourche Parish, LA

Amex acquired a 100% working interest in this property in 1993. Amex, in late
1997, drilled two (2) new field wells (one productive and one dry hole) and
continued to upgrade its field facilities. These operations increased production
by 4 MMCFGPD.

Valentine Field, Lafourche Parish, LA

Amex, for the account of all working interest owners, negotiated a Joint 3-D
Seismic Program with a major oil and gas company ("Program Partner"). The
salient points of the contract are as follows:

1.       Amex and partners will reserve all existing production and existing
         well bores. Amex has a 47.5% working interest and Optima has a 40%
         working interest.

2.       Amex and partners will assign to Program Partner 50% of their leasehold
         interest within a 100 square mile area, approximately 10,576 gross
         acres. This results in a combined working interest of Optima and Amex
         of 43.75%.

3.       Program Partner, at its cost, will option jointly approved unleased
         prospective acreage, totalling approximately 18,742 acres and permit
         the remaining acreage necessary to acquire the 3-D survey. Acreage
         currently under option and lease totals 29,318 gross acres.

4.       Program Partner at its cost will design and acquire an approximate 100
         square mile 3-D survey and deliver one complete data set to Amex in the
         third quarter of 1998.

5.       All further cost to reprocess, interpret, exercise lease options, lease
         additional acreage and drill and develop the Valentine area will be on
         an actual cost basis borne by all working interest owners.

Amex will be the operator of the exploration, development and operations of the
Valentine prospect. Program Partner is to act as operator of the 3-D survey
design and acquisition.

Additional South Louisiana and Zone 1

Amex currently has under lease, seismic options or is in the process of
assembling 5 prospects in this area covering 2,328 acres. South Louisiana and
Zone 1 will continue to be a core area of exploration and development where Amex
anticipates spending 25% to 40% of its annual budget.

CENTRAL AND WESTERN GULF OF MEXICO

Eugene Island 147, Jaguar Prospect

Amex acquired a 18.75% interest in this property in 1995. Amex drilled and
logged several productive zones on this prospect in early 1996. One quarter of
the block is currently under farmout to TDC which plans a 2-3 well development
program in the first half of 1998. Should TDC not drill the planned wells, the
acreage will revert back to Amex. Amex also maintains a higher risk development
project which it expects to test in the next 18-24 months.

<PAGE>   48
Brazos Block 446, Texas Offshore State Waters, Pompano

Amex acquired a 44% interest in this property in late 1996. It anticipates
drilling 1-2 development/exploratory wells by the end of 1999. Current
production is approximately 4.5 MMCFGPD from three wells.

High Island 494, Snapper Prospect

Amex acquired a 29% interest this property in late 1996. It anticipates the
drilling of 1-2 exploratory wells during 1998. Current production is
approximately 1 MMCFGPD from one well.

Galveston Block 303, Barracuda Prospect

Amex acquired a 21.875% interest in this property in 1996. Amex along with its
partner, Burlington Resources (Operator), has completed the initial phase of
exploration and development of this field. Current production is approximately
26 MMCFGPD from four wells. In addition to drilling and completing 3 wells, one
well and a production platform were acquired.

Other Properties

Amex has in inventory five prospects in the Central and Western Gulf of Mexico,
inclusive of the above prospects. Amex plans to continue to expand its
activities in the Gulf of Mexico where it anticipates spending 60% - 75% of its
annual budget.

         successful in the subject reservoir. There is relatively little
         engineering and geological risk associated with these reserves.

(2)      "Proved Producing Reserves" are those proved reserves that are actually
         on production or if not producing, that could be recovered from
         existing wells or facilities or where the reasons for the current
         non-producing status is the choice of the owner rather than the lack of
         markets or some other reason. "Proved Undeveloped Reserves" are
         reserves that have been drilled and casing run through the zone. A
         workover may be required to place these reserves on producing status.

                                      -42-
<PAGE>   50
         "Proved Non-Producing Reserves" are proved reserves that are currently
         not producing either due to lack of facilities and/or markets.
(3)      "Probable Additional Reserves" are those reserves which analysis of
         drilling, geological, geophysical and engineering data does not
         demonstrate to be proved under current technology and existing economic
         conditions, but where such analysis suggests the likelihood of their
         existence and future recovery. Probable Additional Reserves to be
         obtained by the application of enhanced recovery processes will be in
         the increased recovery over and above that estimated in proved
         category. THERE IS SOME DEGREE OF GEOLOGICAL AND ENGINEERING RISK
         ASSOCIATED WITH PROBABLE RESERVES. ADJUSTMENTS WERE MADE TO THE FUTURE
         NET PRODUCTION REVENUE FROM PROBABLE RESERVES TO ACCOUNT FOR THE
         GEOLOGICAL AND ENGINEERING RISK ASSOCIATED WITH THESE RESERVES. The
         risk associated with the probability of obtaining production from
         probable reserves has been assessed at 50%.
(4)      Constant pricing in U.S. dollars for U.S. properties, on a property by
         property basis, adjusted for quality, transportation and heating value
         where necessary, have been used in the DOR report. Base product prices
         used were US$2.24/MMBTU for gas, US$17.00 BBL for oil and condensate.

NOTES:

(1)      "Gross Wells" refers to all wells in which Amex participated.
(2)      "Net Wells" refers to the aggregate of the percentage working interest
         of Amex in Gross Wells.
(3)      "Dry Wells" refers to a well which is not a productive well or a
         service well. A productive well is a well which is capable of producing
         oil or gas in commercial quantities considered by the operator to be
         sufficient to justify the costs required to complete, equip and produce
         the well. A service well refers to a well such as a water or gas
         injection or water-disposal well. Such wells do not have marketable
         reserves of crude oil or natural gas attributed to them but are
         essential to the production of the crude oil and natural gas reserves.

</TABLE>


VARIATIONS IN OPERATING RESULTS
TWELVE MONTHS ENDED DECEMBER 31, 1997 TO DECEMBER 31, 1996
1997 oil and gas sales increased US$2,200,000 over 1996 or 50%. This was
primarily due to the drilling activity at Galveston Block 303. Three wells were
placed on production in 1997 resulting in increased gas sales of 3,900 mcf/day.
Product prices did not change significantly between years averaging US$20.02/bbl
and US$2.38/mcf in 1996 compared to US$19.58/bbl and US$2.45/mcf in 1997.

Operating Expenses. Operating expenses increased from US$1,400,000 to
US$2,300,000 or 66%. This was caused by the additional wells at Galveston Block
303 as well as increased operating expenses at the Bully Camp Field due to its
age.

Production Taxes. Production taxes remained relatively constant even though
revenue and production increased because the increase was offshore in Federal
waters where no severance taxes are paid.

Depletion, Depreciation and Amortization. Depreciation, depletion and
amortization increased 150% in 1997 because of the production profile of
Galveston Block 303 and the lack of production history for the related wells.
Typically, an offshore well will produce at high rates. In addition, as with
most wells, there has not yet been enough production history to support
additional proved reserves. Also, the investment in oil and gas properties
increased US$6,000,000.

General and Administrative Expense. General and administrative expenses
increased US$100,000 in 1997. This is due to an increase in the management fee
paid to American Explorer, Inc. which resulted from the addition of employees to
generate properties for Amex and manage its affairs. The increase would have
been more except the management fee was suspended for the last four months of
the year because of cash requirements for drilling commitments of Amex during
the last part of 1997.

Interest Expense. Interest expense decreased for 1997 because of lower debt
levels during the year. The note at December 31, 1996 was paid down during the
beginning of the year to an insignificant amount from July though September.
Beginning in October, draws on the new line began.

LIQUIDITY AND CAPITAL RESOURCES
Working capital (before considering debt) decreased from a negative of
US$500,000 to a negative of US$800,000. This was caused by an increase in
drilling activity during the last one and one half months of 1997 partially
offset by the increase in revenues discussed above. Two wells were drilled at
the Bully Camp Field during this period for a total cost to Amex of
US$2,000,000. One well was completed as a gas well and the other was a dry hole.

In October, 1997, Amex entered into a new agreement with a bank for a reducing
revolving line of credit. The initial borrowing base was US$4,000,000 which
reduced US$220,000 per month through February,


                                      -45-
<PAGE>   53
1998 when it was redetermined and set at US$3,700,000 effective April 1, 1998.
This borrowing base reduces US$210,000 per month and is redetermined
semi-annually.

Cash flow from operations was US$3,700,000 in 1997. This cash flow, the
additional bank debt, and the decrease in working capital were used to add to
the evaluated oil and gas properties as well as fund an additional US$1,000,000
in unevaluated properties.

Amex presently has no commitments regarding capital expenditures and believes
that its current sources of liquidity are sufficient to fund its current
operations. However, in order to continue its exploration and development
activities, Amex will need additional financing. Assuming consummation of the
Merger Transaction, cash held by Optima of approximately $5,660,354 (as of
December 31, 1997) would be available for these activities. In addition Amex
anticipates that in the future it will need financing in addition to the cash
held by Optima to pursue its exploration and development strategy, which may
include the sale of equity and debt securities and additional bank financing.
There can be no assurances that such additional financing will be available on
acceptable terms, if at all.

DESCRIPTION OF SHARE CAPITAL
Since Amex is a Louisiana limited liability company, no stock has been issued.
Its ownership is thirty-five percent (35%) by Goodson, thirty-five percent (35%)
by NAB and thirty percent (30%) by Dexco.

CAPITALIZATION
The following table sets forth the capitalization of Amex as of December 31,
1997:

</TABLE>

PRIOR SALES
In May, 1997 Goodson, Dexco and NAB contributed their interests in the Valentine
Field to Amex. As a result, the ownership in Amex changed from thirty-three and
one third percent (33.33%) for each member to thirty-five percent (35%) for each
of Goodson and NAB and thirty percent (30%) for Dexco. During 1997, Robert R.
Brooksher was granted an option to purchase five percent (5%) of the membership
interest of the members.

LEGAL PROCEEDINGS
There are no suits, actions, claims, investigations, reviews, or other proceeds
pending or, to the knowledge of Amex or the Target Corporations, threatened
against Amex or any of the Target Corporations.

Robert R. Brooksher                       Chief Financial Officer
</TABLE>

EXECUTIVE COMPENSATION
None of the officers or directors of Amex presently have employment agreements
with Amex. However, the Merger Agreement provides that as a condition to
closing, Messrs. Goodson, Thomas, Daigle and Brooksher will each enter into an
employment agreement with Optima providing for annual salaries of US$210,000,
US$210,000, US$180,000 and US$180,000, respectively (the "Employment
Agreements"). The Employment Agreements provide for a three year term, with
automatic one year renewals thereafter unless terminated. The Employment
Agreements also provide for termination with or without cause (as defined), with
12 months severance provided in the event of termination without cause. Each
employment agreement also contains a non-competition agreement prohibiting the
employee from competing with Optima during his employment and for one year after
termination of the agreement for cause or by the employee for any reason.

OPTIONS TO PURCHASE SECURITIES
Robert R. Brooksher holds an option to purchase up to 5% of the percentage
ownership in Amex , which option, if not exercised prior to the closing of the
Merger Transaction, shall continue in up to 5% of the aggregate Optima's common
shares and contingent stock issue rights issued to the stockholders and members
of the Target Corporations as a result of the Merger Transaction.

Each of the Target Corporations has granted a security interest in all of its
membership interests in Amex to Compass Bank to secure Amex's obligations under
its bank facility, which security interest is to be released on or prior to the
closing of the Merger Transaction.

Except as directed above, there are no outstanding subscriptions, options,
rights, warrants or other agreements or commitments of any kind obligating
Goodson and Dexco to issue any security of or equity interest in Goodson and
Dexco or obligating Amex and NAB to issue any membership interest in Amex or
NAB.

INTEREST OF MANAGEMENT AND OTHERS IN MATERIAL TRANSACTIONS
Amex has no employees. It is managed by American Explorer, Inc. ("AEI"), a
corporation owned by two members of Amex. In addition, AEI is the operator of
certain of the oil and gas wells in which Amex has an interest. In 1997 and
1996, AEI charged Amex management fees of US$520,000 and US$444,000,

development effort (see Note A of Amex's financial statement attached as
Appendix E to this Proxy Statement) in 1997 and 1996, respectively. The
remainder is included in general and administrative expense. At December 31,
1997, and 1996 Amex owed AEI approximately US$2,458,000, and US$1,423,000,
respectively. In June, 1997, the members contributed their interests in the
Valentine Field to Amex. The contribution was recorded at the amount of the
members' cost in the Valentine Field of approximately US$53,000.

CONTINUATION INTO THE STATE OF DELAWARE

GENERAL
Optima is presently a corporation formed and operating under the Canada Business
Corporations Act ("CBCA"). The shareholders of the Company will be asked at the
AGM to pass a Special Resolution (the "Continuation Resolution") authorizing the
Company to continue in the State of Delaware under the Delaware General
Corporation Law (the "DGCL") pursuant to section 388 thereof (the
"Continuation"), thereby continuing the Company as if it had been originally
incorporated under the DGCL as a Delaware corporation. The Continuation
Resolution also provides for approval of the Delaware Certificate of
Incorporation (substantially in the form attached as Appendix C to this Proxy
Statement) and alters the Company's authorized capital from an unlimited number
of common shares without par value to 75,000,000 shares of Common Stock and
5,000,000 shares of Preferred Stock, each with a par value of US$.001 per share.

Upon Continuation, the CBCA ceases to apply and the DGCL becomes applicable to
the Company as if it had been originally incorporated in Delaware.

The Continuation will not result in any change in the business of the Company or
its assets, liabilities, net worth or management. However, the Board of
Directors may increase the size of the Company's Board of Directors after the
Continuation (see "Corporate governance Differences - Size of the Board of
Directors"). A shareholder's holdings will not change. The Continuation is not a
reorganization, amalgamation or merger.

Upon consummation of the Continuation, the Company will file a Current Report on
Form 8-K with the SEC to reflect the Continuation for the purposes of Section
15(d) of the Exchange Act.

The Continuation gives rise to a Right of Dissent (see "Right of Dissent"
below). If the Right of Dissent is exercised by any of the Company's
shareholders entitled to do so, and the Company effects the Continuation, the
Company would be required to purchase for cash the dissenting shareholder's
shares in the Company at the fair value of the shares as at the close of
business on the day before the Continuation Resolution is adopted, subject to
the CBCA. This could have an adverse effect on the Company. The Continuation
Resolution will, therefore, provide authority to the Board of Directors not to
proceed with the Continuation if, in the Board's opinion, it is not in the best
interest of the Company to do so.

PRINCIPAL REASONS FOR CONTINUATION
For many years, Delaware has followed a policy of encouraging incorporation in
that State and, in furtherance of that policy, has adopted comprehensive, modern
and flexible corporate laws, which are periodically updated and revised to meet
changing business needs. As a result, many major corporations have initially
chosen Delaware for their domicile or have subsequently reincorporated in
Delaware in a manner similar to that proposed by the Company. Because of
Delaware's long standing policy of encouraging incorporation in that State, and
consequently its pre-eminence as the State of incorporation for many major
corporations, the Delaware courts have developed considerable expertise in
dealing with corporate issues and a substantial body of case law has developed
construing Delaware law and establishing public policies with respect to
Delaware corporations.


                                      -48-
<PAGE>   56
Because the Company's business focus has shifted from Canada to the United
States, Management believes that it is preferable to be governed by the laws of
a State of the United States. For example, the CBCA requires that a majority of
the Directors of the Company must be ordinarily resident in Canada. It is a
continuing problem for the Company to find qualified individuals in Canada who
are prepared to act as Directors and assume the responsibilities, the expense
and the risk that are inherent with acting as a Director of a company whose
property interests are all in the United States. Management is, therefore, of
the opinion that it is preferable to eliminate this Canadian residency
requirement.

In addition, most of the Company's shareholders are in the United States. The
Company's shares are registered under the United States Securities Exchange Act
of 1934 (the "Exchange Act") and the Company is subject to the Exchange Act
reporting requirements. However, as a CBCA company, the Company is also subject
to the reporting requirements under Canadian law and to Canadian tax law and
rules. The U.S. and Canadian tax and securities reporting requirements often are
in conflict. As a result, the Company must retain both United States and
Canadian securities counsel and tax accountants, which is very expensive for the
Company and very time-consuming for Management. By changing its jurisdiction of
incorporation from the CBCA to Delaware, the Company will simplify its
securities and tax reporting requirements. Consequently, the Company believes
the Continuation will result in substantial savings to the Company.

In connection with the proposed change in the Company's jurisdiction of
incorporation from the CBCA to the State of Delaware, the Board of Directors has
proposed that the par value of the shares of the Company's Common Stock be
changed from no par value to $.001 par value per share because the Delaware
franchise fees applicable to no par value shares are significantly higher than
those for $.001 par value shares. Par value represents the minimum consideration
which must be received by the Company for the issuance of a share of stock. The
change in par value will have no effect upon the rights of existing security
holders. By voting in favour of the Continuation, the shareholders are voting in
favour of the change in par value of the Company's Common Stock. If the
resolution is approved, the change will be reflected in the new Delaware
Certificate of Incorporation which will be filed with the Delaware Secretary of
State's Office.

CONTINUANCE A CONDITION OF MERGER AGREEMENT
The Merger Agreement is subject to certain conditions, including without
limitation, the receipt of all regulatory approvals required for the
consummation of the Merger Transaction, Optima shareholders' approval to the
matters set forth in this Proxy Statement requiring shareholders' approval, the
Continuation of Optima into Delaware and the holders of no more than 1% of
Optima shares, in aggregate, shall have delivered written demand for appraisal
of such shares pursuant to the dissent rights under the CBCA (see "Continuation
into the State of Delaware - Right of Dissent").

CORPORATE GOVERNANCE DIFFERENCES
In approving the Continuation, shareholders of the Company will be approving the
form of Certificate of Incorporation (substantially in the form attached as
Appendix C to this Proxy Statement) and the Bylaws and will be agreeing to hold
securities in a corporation governed by Delaware law. In exercising their vote,
shareholders should consider the distinctions between Delaware law and the CBCA,
some of which are outlined below.

The DGCL and the Company's Delaware Certificate of Incorporation and Bylaws
differ in many respects from the CBCA and the Company's charter documents. This
Proxy Statement summarizes the principal differences that could materially
affect the rights of shareholders of the Company. The following summaries of
certain provisions of the Company's Certificate of Incorporation and Bylaws do
not purport to complete and are subject to, and are qualified in their entirety
by, reference to all of the provisions of the Company's Delaware Certificate of
Incorporation and Bylaws which are available for review by


                                      -49-
<PAGE>   57
shareholders of the Company's offices at 600 - 595 Howe Street, Vancouver,
British Columbia, Canada, V6C 2T5 during business hours and at the AGM.

SHAREHOLDER QUORUM. Under the Company's current Articles, two shareholders (or
proxy holders representing shareholder(s)) holding shares representing in the
aggregate at least 60% of the issued and outstanding shares of the Company that
are entitled to attend and vote at such meeting constitutes a quorum at any
meeting of shareholders. Under Delaware law a corporation's Certificate of
Incorporation and Bylaws may specify the number of shares necessary to
constitute a quorum at any meeting of shareholders; provided, however, that a
quorum may not consist of less than one-third of the shares entitled to vote at
the meeting. The Company's Delaware Bylaws provide that, in general, one-half of
the issued and outstanding shares entitled to vote, present in person or
represented by proxy, is required for a quorum at a meeting of shareholders.

SUPERMAJORITY. Both jurisdictions permit the adoption of a higher requisite vote
for certain types of corporate action, subject to certain limitations.
Notwithstanding any provision contained in a corporation's memorandum and
articles, the CBCA provides that two-thirds of the votes present and voting at a
general meeting of shareholders on a special resolution is required to amend the
Company's charter documents, including changing the corporation's name or
altering its share capital, or any of the rights attached thereto and for
certain extraordinary corporate transactions. Under the DGCL, an amendment to a
corporation's certificate of incorporation requires the approval of a majority
of the outstanding shares entitled to vote, unless such level of approval is
increased by the certificate of incorporation. In addition, under the DGCL, if
an amendment to the certificate of incorporation adversely affects the rights of
a particular class of shares, that class is entitled to vote separately on the
amendment whether or not it is designated as voting shares.

AMENDMENT OF BYLAWS. The CBCA provides that directors may, subject to any
restriction in the articles, bylaws or a unanimous shareholder agreement, make,
amend or repeal any bylaws, but that any such action of the directors is subject
to the later confirmation by resolution passed by a majority of the votes cast
by the shareholders entitled to vote on the resolution. Under the DGCL,
directors of a corporation, if authorized by the certificate of incorporation,
may adopt, amend or repeal bylaws, such action not being subject to later
shareholder confirmation. The Company's Delaware Bylaws provides that any Bylaws
made by the Board of Directors may be altered, amended or repealed by the
Directors or the shareholders, provided the Bylaws shall not be altered, amended
or repealed by shareholder action without the affirmative vote of at least
two-thirds of the then outstanding shares entitled to vote generally in the
election of directors, alter or repeal the Bylaws.

REMOVAL OF DIRECTORS. Under both the CBCA and DGCL, directors may generally be
removed with or without cause, by a vote of the holders of a majority of the
shares being voted. However, under the DGCL, if the board is classified,
directors may be removed only for cause, unless the certificate of incorporation
provides otherwise. Further, if a director is elected by holders of a class of
series of shares, the CBCA provides that only the shareholders of that class or
series can vote to remove that director, with or without cause, where the DGCL
provides that only the shareholders of the class or series can vote to remove
that director without cause.

BOARD VACANCIES. Under the CBCA, a quorum of directors may generally fill a
vacancy among the directors, except a vacancy resulting from an increase in the
number of directors or a failure to elect the number of directors required at
any meeting of shareholders. If there is not a quorum of directors or if there
has been a failure to elect the number of required directors, the remaining
directors are required to call a meeting of shareholders to fill the vacancy. If
any class of shareholders has the right to elect a director or


                                      -50-
<PAGE>   58
directors and a vacancy occurs among such directors, the remaining directors
elected by such class shall fill the vacancy except a vacancy created by an
increase in the number of directors for that class or from a failure to elect
the required number of directors for that class. If there are no remaining
directors from a class entitled to fill a vacancy, any holder of shares of that
class may call a meeting of shareholders for the purpose of filling the vacancy.

Under the DGCL, vacancies and newly created directorships may be filled by a
majority of the remaining directors, although less than a quorum, or by a sole
remaining director. If any class of shareholders has the right to elect one or
more directors, any vacancy or newly created directorship of such class or
series may be filled by the remaining directors elected by such class then in
office. If at any time there are no directors in office, any officer or
shareholder may call a special meeting of shareholders for the purpose of
filling the vacancy.

REQUIRED APPROVALS OF SHAREHOLDERS. The CBCA requires that various extraordinary
corporate transactions, such as a merger, the sale of substantially all of a
corporation's assets or the change of jurisdiction, must be approved by
two-thirds of the votes represented and voting at the meeting called for such
purpose. Under the DGCL, mergers or consolidations require the approval of the
holders of a majority of the outstanding shares of the corporation entitled to
vote thereon except (i) for a corporation which survives the merger where the
merger requires the issuance of common shares not exceeding 20% of such
corporation's shares outstanding immediately prior to the merger, the merger
agreement does not amend in any respect the survivor's certificate of
incorporation, and shareholder approval is not specifically mandated in the
survivor's certificate of incorporation; and (ii) for both corporations where
the corporation surviving the merger was a 90% parent of the other corporation.
Unless a greater percentage is required by the charter, a sale, lease or
exchange of all or substantially all the property or assets of a corporation or
an amendment to the certificate of incorporation also require the approval of
the holders of a majority of the outstanding shares entitled to vote thereon.
Since a quorum under the Company's current Articles is two persons holding
shares representing in the aggregate at least 60% of the issued and outstanding
shares, as compared to the quorum requirement under the Company's Delaware
Bylaws, which is a 50% of the outstanding shares entitled to vote (see
"Corporate Governance Differences - Shareholder Quorum"), shareholder action can
be taken under the Delaware Bylaws with a smaller percentage of the shareholder
vote than is required under the CBCA.

EXAMINATION OF CORPORATE RECORDS. Under the CBCA, any person is entitled to
examine a corporation's articles and bylaws and all amendments thereto, a copy
of any unanimous shareholder agreement, minutes of meetings and resolutions of
shareholders, notices of directors and change of directors, and securities
register upon payment of a reasonable fee for each document examined. In
addition, any person is entitled, on a payment of a reasonable fee, to a copy of
a list setting out the names of shareholders of the Company on filing an
affidavit with the corporation stating that the list is required for corporate
purposes. "Corporate purposes" is defined to mean any effort to influence the
voting of shareholders of the corporation, an offer to acquire shares of the
corporation, or to effect or any other matter relating to the affairs of the
corporation. Under Delaware law, shareholders have the right for any proper
purpose to inspect, upon written demand under oath stating the purpose for such
inspection, the corporation's stock



                                      -51-
<PAGE>   59
ledger, list of shareholders, and its other books and records, and to make
copies or extracts of the same. A proper purpose means a purpose reasonably
related to a person's interest as a shareholder.

MINORITY (DISSENTERS) RIGHTS. Under the CBCA, all of the shareholders of a
corporation have the right to dissent from certain corporate acts involving (i)
certain amendments to the Company's Articles to add, change or remove any
provisions restricting or constraining the issue, transfer or ownership of
shares of a class or to add, change or remove any restrictions on the business
or businesses that the corporation may carry on, (ii) a continuation of the
corporation into another jurisdiction, (iii) various forms of corporate
amalgamations, or (iv) a sale, lease or exchange of all or substantially all of
its property and to exercise their statutory appraisal rights after such
dissent, receiving a cash payment for the repurchase of their shares. Under
Delaware law, shareholders have the right to dissent and exercise appraisal
rights only with respect to certain forms of corporate transaction and
consolidations. In addition, under Delaware law, appraisal rights are not
available with respect to any shares of stock if, at the record date fixed to
determine the shareholders entitled to vote on such merger or consolidation, (i)
such shares were listed on a national security exchange or (ii) held of record
by more than 2,000 holders, unless, under the terms of an agreement of merger or
consolidation, the shareholders are required to accept for their stock something
other than: (i) shares of stock of the surviving corporation; (ii) shares of
stock of any other corporation which is listed on a national securities exchange
or designated as a national market system security or an interdealer quotation
system by the National Association of Securities Dealers, Inc. ("NASD") or which
has more than 2,000 shareholders of record; (iii) cash in lieu of fractional
shares; and/or (iv) any combination thereof. THEREFORE, IN APPROVING THE
CONTINUATION, SHAREHOLDERS WILL BE AGREEING TO FOREGO THE MORE EXTENSIVE
DISSENTERS' RIGHTS UNDER THE CBCA WITH RESPECT TO FUTURE ACTIONS.

DISQUALIFICATION OF DIRECTORS. The CBCA prohibits the following persons from
serving as a Director: (i) persons under age 18; (ii) persons who are of unsound
mind and have been so found by a court in Canada or elsewhere; (iii) persons who
are not individuals; or (iv) persons who have the status of bankrupts. Delaware
law contains no comparable direct prohibitions.

PERSONAL LIABILITY OF DIRECTORS. The CBCA provides that every Director, in
exercising his or her powers and discharging his or her duties, shall act
honestly and in good faith with a view to the best interests of the corporation
and exercise the care, diligence and skill that a reasonably prudent person
would exercise in comparable circumstances. The CBCA also specifically imposes
joint and several personal liability upon Directors who vote for or consent to a
resolution which authorizes the issuance of shares for a consideration other
than money, to make good any amount by which the consideration received is less
than the fair equivalent of the money that the corporation would have received
if the shares had been issued for money on the date of the resolution, purchase,
redemption or other acquisition of shares, payment of a commission. As action to
enforce a liability related to the foregoing may not be commenced two years
after the date of the resolution authorizing the action complaint of.

In addition, under a number of Canadian federal statutes, Directors are
personally liable for certain of the corporation's debts such as those under the
CBCA which imposes liability for the unpaid wages of employees in an amount not
exceeding six months wages for each employee in the event that the corporation
failed to pay the wages. Other statutes impose personal liability on Directors
for corporate acts which have caused damage to third parties.

The CBCA entitles a shareholder or a Director of the corporation, with the
approval of a court, and in the name of the corporation, to commence legal
proceedings or intervene in an action to which the corporation is a party, for
the purpose of prosecuting, defending or discontinuing an action on behalf of
the corporation.



                                      -52-
<PAGE>   60
Under Delaware law, the directors of a corporation act in a fiduciary capacity
and owe the duties of loyalty and due care to the corporation and its
shareholders.

Under Delaware law, shareholders may bring derivative actions against officers
and directors of the corporation for breach of their fiduciary duty to the
corporation and its shareholders or for other fraudulent misconduct, so long as
the shareholder was a shareholder of the corporation at the time of the
transaction in question or that he or she obtained the stock thereafter solely
by operation of law.

Delaware law permits a corporation to adopt a provision in its Certificate of
Incorporation eliminating the liability of a director to the corporation or its
shareholders for monetary damages for breach of the director's fiduciary duty of
care, except where the liability arises (i) from a breach of the Director's duty
of loyalty to the corporation or its shareholders; (ii) from acts or omissions
not in good faith, involving intentional misconduct or a knowing violation of
law; (iii) from unlawfully paying a dividend, approving Delaware stock
repurchases or redemptions; or (iv) from a transaction where the Director
derived an improper personal benefit. The Company's Delaware Certificate of
Incorporation eliminates the liability of its directors to the fullest extent
permissible under applicable law. The foregoing limitations on monetary damages,
however, have no effect on the standard of care to which directors must conform
or the availability of monetary damages.

INDEMNIFICATION. The Delaware General Corporation Law generally provides that a
corporation shall indemnify a Director against all costs, charges and expenses
actually and reasonably incurred by the Director, including an amount paid to
settle an action or satisfy a judgment in a civil, criminal or administrative
action to which the Director is a party by reason of his having been a Director,
provided that the Director was acting in good faith. The indemnification
permitted under Delaware law is not substantially different in nature of extent
from that permitted under CBCA and currently provided for in the constituent
documents of the Company.

CUMULATIVE VOTING. Under the CBCA and Delaware law, cumulative voting is
permitted only if provided for in a corporation's Articles or Certificate of
Incorporation, respectively. Neither the Company's Bylaws nor the Company's
Delaware Certificate of Incorporation provide for cumulative voting.

LOANS TO OFFICERS AND EMPLOYEES. The CBCA provides that a corporation or any
corporation with which it is affiliated shall not, directly or indirectly, give
financial assistance by means of a loan, guarantee or otherwise, to any
shareholder, director, officer or employee of the corporation or of an
affiliated corporation or to an associate of any such person for any purpose, or
to any person for the purpose of or in connection with a purchase of a share
issued or to be issued by the corporation or affiliated corporation, where there
are reasonable grounds for believing that the corporation is or, after giving
the financial assistance, would be unable to pay its liabilities as they become
due, or the realizable value of the corporation's assets, excluding the amount
of any financial assistance in the form of a loan and in the form of assets
pledged or encumbered to secure a guarantee, after giving the financial
assistance, would be less than the aggregate of the corporation's liabilities
and stated capital of all classes. Notwithstanding the foregoing, a corporation
may give financial assistance by means of a loan, guarantee or otherwise to any
person in the ordinary course of business if the lending of money is part of the
ordinary business of the corporation, to any person on account of expenditures
incurred or to be incurred on behalf of the corporation, to a holding body
corporate if the corporation is a wholly-owned subsidiary of the holding body
corporate, to a subsidiary body corporate of the corporation; and to employees
of the corporation or any of its affiliates, (i) to enable or assist them to
purchase or erect living accommodation for their own occupation, or (ii) in
accordance with a plan for the purchase of shares of the corporation or any of
its affiliates to be held by a trustee. Under Delaware law, a corporation may
make loan subsidies (including directors who are also officers or employees)
when such action, in the judgment of the directors, may reasonably be expected
to benefit the corporation.


                                     - 53 -
<PAGE>   61
REDEMPTION AND REPURCHASE OF SHARES; DIVIDENDS. The CBCA permits a company to
purchase or redeem any redeemable shares issued by it at prices not exceeding
the redemption price stated in the Company's Articles or calculated according to
a formula stated in the Company's Articles. However, a corporation cannot make
any payment to purchase or redeem any redeemable shares issued by it if there
are reasonable grounds for believing that the corporation is, or would after the
payment be, unable to pay its liabilities as they become due, or the realizable
value of the corporation's assets would after the payment be less than the
aggregate of (i) its liabilities, and (ii) the amount that would be required to
pay the holders of shares that have a right to be paid, on a redemption or in a
liquidation, rateably with or prior to the holders of the shares to be purchased
or redeemed. Delaware law permits a corporation to declare and pay dividends out
of surplus or, if there is no surplus, out of net profits for the fiscal year in
which the dividend is declared and/or for the preceding fiscal year as long as
the amount of capital of the corporation following the declaration and payment
of the dividend is not less than the aggregate amount of the capital represented
by the issued and outstanding stock of all classes having a preference upon the
distribution of assets. In addition, Delaware law generally provides that a
corporation may redeem or repurchase its shares only if such redemption or
repurchase would not impair the capital of the corporation.

INTERESTED DIRECTOR TRANSACTIONS. Under the CBCA, contracts or transactions in
which a director of the company has an interest are not invalid because of such
interest provided that certain conditions such as obtaining the required
approval and fulfilling the requirements of full disclosure and reasonableness,
are met. Under the CBCA, after full disclosure by the interested director or
directors, a majority of the directors at a meeting at which a quorum is present
must approve the proposed contract or transaction with the interested director
abstaining from voting but counted in the quorum if so permitted by the
company's articles; or (b) the shareholders must approve the contract or
transaction, which must be fair and reasonable at the time it was entered into.
Otherwise, a court may, on application of the company or any interested person,
set aside the contract as it sees fit. Under Delaware law, if board approval is
sought, the contract or transaction must be approved by a majority of the
disinterested directors (even though less than a majority of a quorum).
Therefore, certain transactions that the board of a CBCA company would lack the
authority to approve, because of the number of interested directors, could be
approved by a majority of the disinterested directors of the Delaware company
representing less than a majority of a quorum. The Company is not aware of any
plans to propose any transactions involving interested directors of the Company
which the Board would lack the authority under the CBCA but could approve under
Delaware law.

ANTI-TAKEOVER EFFECT. Certain provisions of the DGCL and of the Company's
Delaware Certificate of Incorporation and Bylaws, summarized in the following
paragraphs, may be deemed to have an anti-takeover effect and may delay, defer
or prevent a hostile tender offer or takeover attempt that a shareholder might
consider in his or her best interest, including those attempts that might result
in the payment of a premium over the market price for the shares held by
shareholders. Despite such anti-takeover implications, this Continuation
Resolution is not intended to prevent an acquisition of the Company and
Management is not aware of any effort to accumulate the Company's securities or
to obtain control of the Company by means of a merger, tender offer or
solicitation in opposition to management or otherwise.

DELAWARE ANTI-TAKEOVER LAW. Section 203 of the DGCL (the "Delaware Takeover
Statute") applies to a Delaware corporation with a class of voting stock listed
on a national securities exchange, authorized for quotation on an interdealer
quotation system or held of record by 2,000 or more persons. In general, Section
203 prevents an "interested shareholder" (defined generally as any person
owning, or who is an affiliate or associate of the corporation and has owned in
the preceding three years, 15% or more of a corporation's outstanding voting
stock and affiliates and associates of such person) from engaging in a "business
combination" (as defined) with a Delaware corporation for three years following
the date such


                                     - 54 -
<PAGE>   62
person became an interested shareholder unless (i) before such person became an
interested shareholder, the Board of Directors of the corporation approved
either the business combination or the transaction that resulted in the
shareholder becoming an interested shareholder; (ii) the interested shareholder
owned at least 85% of the voting stock of the corporation outstanding at the
time the transaction commenced (excluding stock held by Directors who are also
officers of the corporation and by employee stock plans that do not provide
employees with the rights to determine confidentially whether shares held
subject to the plan will be tendered in a tender or exchange offer); or (iii) on
or subsequent to the date such person became an interested shareholder, the
business combination is approved by the Board of Directors of the corporation
and authorized at a meeting of shareholders by the affirmative vote of the
holders of two-thirds of the outstanding voting stock of the corporation not
owned by the interested shareholder. Under Section 203, the restrictions
described above do not apply to certain business combinations proposed by an
interested shareholder following the announcement or notification of one of
certain extraordinary transactions involving the corporation and a person who
had not been an interested shareholder during the previous three years or who
became an interested shareholder with the approval of a majority of the
corporation's directors. The Delaware Certificate of Incorporation provides that
the Company has opted out of Section 203.

SIZE OF THE BOARD OF DIRECTORS. The CBCA requires a public company to have no
fewer than three directors. Delaware law permits the corporation to adopt a
provision in its certificate of incorporation or bylaws authorizing the board of
directors alone to change the authorized number or the range of directors by
amendment to the bylaws. The Company's Delaware Certificate of Incorporation
provides that the number of directors of the Company will be as specified in its
Bylaws and authorizes the Board of Directors to make, alter, amend or repeal the
Bylaws. The ability of the Board of Directors to alter the size of the Board
without shareholder approval enables the Company to respond quickly to a
potential opportunity to attract the services of a qualified director or to
eliminate a vacancy for which a suitable candidate is not available. The
Company's Delaware Bylaws provide for a maximum of 12 directors.

SPECIAL MEETING OF SHAREHOLDERS. The CBCA provides that the board of directors
or the holders of five percent (5%) of the issued shares with a right to vote
can call a special meeting. Under Delaware law, a special meeting may be called
by the Board of Directors or by any other person authorized to do so in the
corporation's Certificate of Incorporation or Bylaws. The Delaware Bylaws of the
Company authorize (i) the Board of Directors, (ii) the Chairman of the Board,
(iii) the Chief Executive Officer (iv) the President to call a special meeting;
or by one or more stockholders holding shares in the aggregate entitled to cast
not less than two-thirds of the issued and outstanding shares entitled to vote.

SHAREHOLDER CONSENT IN LIEU OF MEETING. Under the CBCA, a shareholder action
without a meeting may only be taken by written resolution signed by all
shareholders who would be entitled to vote thereon at a meeting. Under the DGCL,
unless otherwise provided in the charter, action by shareholders may be taken
without a meeting if a consent in writing is signed by the holders of
outstanding shares having not less than the minimum number of votes that would
be necessary to authorize such action at a meeting at which all shares entitled
to vote were present and voted.

ADVANCE NOTICE REQUIREMENTS FOR SHAREHOLDER PROPOSALS AND DIRECTOR NOMINATIONS.
The Company's Delaware Bylaws provide that shareholders seeking to bring
business before an annual meeting of shareholders, or to nominate candidates for
election as directors at an annual or a special meeting of shareholders, must
provide timely notice thereof in writing. To be timely, a shareholder's notice
must be delivered to, or mailed and received at, the principal executive offices
of the company (i) in the case of an annual meeting no later than the close of
business 120 days before the date specified in the company's proxy statement
released to shareholders in connection with the prior year's annual meeting of
shareholders, and (ii) in the case of a special meeting of shareholders, not
later than the close of business 60 days before the date of the meeting. The
Company's Delaware Bylaws specify certain requirements


                                     - 55 -
<PAGE>   63
for a shareholder's notice to be in proper written form. These provisions may
preclude some shareholders from bringing matters before the shareholders at an
annual or special meeting or from making nominations for Directors at an annual
or special meeting.

Under the CBCA, a shareholder entitled to vote at an annual meeting of
shareholders may submit to the corporation notice of any matter that he proposes
to raise at the meeting, hereinafter referred to as a "proposal" and discuss at
the meeting any matter in respect of which he would have been entitled to submit
a proposal. A corporation that solicits proxies shall set out the proposal in
the management proxy circular or attach the proposal thereto. If so requested by
the shareholder, the corporation shall include in the management proxy circular
or attach thereto a statement by the shareholder of not more than two hundred
words in support of the proposal, and the name and address of the shareholder. A
proposal may include nominations for the election of directors if the proposal
is signed by one or more holders of shares representing in the aggregate not
less than five per cent of the shares or five per cent of the shares of a class
of shares of the corporation entitled to vote at the meeting to which the
proposal is to be presented, but this subsection does not preclude nominations
made at a meeting of shareholders. A corporation is not required to comply with
the foregoing if the proposal is not submitted to the corporation at least
ninety days before the anniversary date of the previous annual meeting of
shareholders; it clearly appears that the proposal is submitted by the
shareholder primarily for the purpose of enforcing a personal claim or
redressing a personal grievance against the corporation or its directors,
officers or security holders, or primarily for the purpose of promoting general
economic, political, racial, religious, social or similar causes; the
corporation, at the shareholder's request, included a proposal in a management
proxy circular relating to a meeting of shareholders held within two years
preceding the receipt of such request, and the shareholder failed to present the
proposal, in person or by proxy, at the meeting; substantially the same proposal
was submitted to shareholders in a management proxy circular or a dissident's
proxy circular relating to a meeting of shareholders held within two years
preceding the receipt of the shareholder's request and the proposal was
defeated; or the rights conferred by this section are being abused to secure
publicity.

REGULATORY APPROVAL

The Company will apply to the Director, CBCA for permission to continue and will
file with the Secretary of the State of Delaware to continue the Company to the
State of Delaware. Filings must also be made with the TSE and NASDAQ. Such
approval must be obtained for the continuation to take place. There are no other
regulatory approvals necessary for consummation of the continuance.

CANADIAN INCOME TAX CONSIDERATIONS

The following sections summarize certain provisions of Canadian federal income
tax laws that may affect the Company and its shareholders. Although this summary
discusses the principal tax considerations deemed by the Company to be material,
it does not purport to discuss all of the Canadian federal tax consequences that
may be relevant to its shareholders, nor will it apply to the same extent or in
the same way to all shareholders. No information is provided in this commentary
with respect to the effect of any state, local or provincial tax law, rule or
regulation nor is any information provided as to the effect of any foreign tax
law, other than the federal law of Canada to the extent specifically set forth
in this commentary. EACH SHAREHOLDER IS URGED TO CONSULT WITH HIS OR HER OWN
INDIVIDUAL TAX ADVISOR WITH RESPECT TO THE TAX CONSEQUENCES TO SUCH SHAREHOLDER
OF THE DOMESTICATION.

NO ADVANCE TAX RULING OR INTERPRETATION HAS BEEN OR WILL BE SOUGHT FROM ANY
TAX AUTHORITY WITH RESPECT TO ANY OF THE TRANSACTIONS DISCUSSED IN THIS
COMMENTARY.

CANADIAN TAX IMPLICATIONS TO CANADIAN SHAREHOLDERS

The following commentary is confined to provisions of the Income Tax Act
(Canada) (the "Tax Act"), Regulations to it and amendments publicly announced at
this date and, where applicable, is based on the Company's tax advisors'
understanding of current administrative practices of Revenue Canada, Customs,
Excise and Taxation ("Revenue Canada"). No assurance can be given that the
consequences will not be altered by future changes to administrative practices,
judicial decisions or amendments to the law. This discussion addresses in a
general manner the more pertinent Canadian federal income tax consequences to
the Company and to shareholders of the Company, to whom shares of the Company
constitute "capital property" for purposes of the Tax Act, who deal at arms'
length with the Company and who (with persons not acting at arms' length) hold
less than a 10% interest in the Company. Generally speaking, shares of the
Company will be considered capital property unless the holder is a trader or
dealer in securities, has acquired the shares as part of an adventure in the
nature of trade, or holds the shares otherwise than for investment purposes.

Consequences of Optima Continuation to Canadian Shareholders

The Optima Continuation is not considered to give rise to a disposition of the
shares of the Company by its shareholders and is not considered to be a taxable
event to the shareholders. Shareholders of the Company will continue to hold
their shares in the Company following the Optima Continuation at their adjusted
cost basis of the shares immediately before the Optima Continuation. Shares of
the Company will constitute "foreign property" for purposes of deferred income
plans such as RRSP's. As such, any deferred income plans holding such shares are
advised to carefully review their foreign property limits. Depending on the
extent of the interest held, a Canadian resident shareholder may be required to
report his holdings pursuant to new foreign property reporting rules first
advanced in the 1995 Canadian Federal Budget, and pursuant to draft foreign
reporting requirements released on March 5, 1996 as subsequently revised.
Dividends received after the Optima Continuation will no longer be from a
Canadian corporation and accordingly will no longer generate a dividend tax
credit. Withholding tax imposed by the United States may give rise to a foreign
credit tax which may be applied within defined limits as a credit against
Canadian federal income tax.

Consequences of Optima Continuation to the Company

Upon the Optima Continuation, the Company will be deemed to have had a fiscal
year end immediately before the Optima Continuation and will be deemed to have
disposed of each of its properties and to have immediately reacquired them at
their then fair market values. Any resulting gains or losses from such deemed
dispositions will be taken into account in calculating the Company's taxable
income for the fiscal year thus deemed to have ended. Depreciation taken in
excess of fair market values may be "recaptured" and added into income of the
Company. Capital gains may be generated. Three-quarters of any capital gain
being the excess of deemed net proceeds (at fair market value) over cost for tax
is included in income. Three-quarters of any loss is deductible only against
taxable capital gains for that year and the three previous years. However,
income arising from these gains may be offset by net operating loss carry
forwards from the previous seven years. After the Optima Continuation, for
Canadian tax purposes, any unapplied net operating losses will be available to
offset Canadian source net income only.

The Tax Act as well imposes a special branch tax in these circumstances
calculated on the amount by which the aggregate fair market value of the
Company's property immediately before Optima Continuation exceeds the aggregate
of its liabilities (including liability for income tax for the final taxation
year) and the paid up capital of all of its issued and outstanding shares. The
general rate of tax is 25% of such amount but, pursuant to the Canada/U.S. Tax
Treaty, the rate of tax is reduced to 5%.


                                     - 57 -
<PAGE>   65
Upon the Optima Continuation, the Company is deemed to have been incorporated in
Delaware and not to have been incorporated elsewhere. The Company will,
therefore, cease to be resident in Canada for purposes of the Tax Act, so long
as its "mind and management" is not exercised from Canada. In any event, for
most purposes the Canada/U.S. Tax Treaty would deem the Company to be resident
in the U.S. after the Optima Continuation. As such it would subsequently
generally only be subject to Canadian tax in respect of business income
attributable to a permanent establishment in Canada, gains realized on
disposition of taxable Canadian property and withholding tax in respect of
Canadian source passive income.

A branch tax will be imposed upon business profits realized by a branch
operation if the Company retains business operations in Canada. This tax imposed
at the reduced treaty rate of 5%, is payable upon business profits earned in
Canada minus a deduction for corporate income taxes payable upon those profits
and after the deduction of a special reserve allowed for net assets computed by
prescribed rules, invested in Canada.

It is a condition of the Merger Agreement that no tax liability shall be due and
owing by Optima under applicable Canadian law as a result of the Continuation.

UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

GENERAL

The following is a summary of the material United States federal income tax
consequences of the Continuation to both U.S. Holders and Non-U.S. Holders (as
such terms are defined below) and the material United States federal income and
estate tax consequences to Non-U.S. Holders of holding and disposing of the
stock of the Company. This discussion is based on the United States Internal
Revenue Code of 1986, as amended (the "Code"), existing and proposed regulations
thereunder, Internal Revenue Service ("IRS") rulings and pronouncements, reports
of congressional committees, judicial decisions and current administrative
rulings and practice, all as in effect on the date hereof. This discussion is
based on current law, which is subject to change. Any such change could be
retroactive and, accordingly, could modify the tax consequences discussed
herein. No ruling from the IRS with respect to the matters discussed herein has
been requested and there is no assurance that the IRS agree with the conclusions
set forth in this discussion. In addition, no tax opinion has been requested or
received by the Company with respect to the United States federal income tax
consequences of the Continuation.

This discussion does not address tax considerations applicable to U.S. Holders
(as defined below) of 10% or more (by vote or value) of the stock of the Company
who may be required to include amounts of income as a consequence of the
Continuation. In addition, the discussion below does not address all of the
United States federal income tax consequences that may be relevant to particular
shareholders in light of their personal circumstances or to certain types of
shareholders (such as dealers in securities, insurance companies, foreign
individuals and entities, financial institutions and tax-exempt entities) who
may be subject to special treatment under the federal income tax laws. This
discussion also does not address the federal income tax consequences to
shareholders who acquired their stock of the Company through the exercise of
employee stock options or otherwise as compensation. Furthermore, this
discussion does not address any tax consequences under state, local or foreign
laws.

COMPANY SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE
UNITED STATES FEDERAL, STATE, LOCAL AND OTHER TAX CONSIDERATIONS OF
PARTICIPATING IN THE CONTINUATION AND OF HOLDING AND DISPOSING OF SHARES OF THE
COMPANY AFTER THE CONTINUATION.


                                     - 58 -
<PAGE>   66
The term "U.S. Holder" means a beneficial owner of the stock of the Company that
is for United States federal income tax purposes (i) a citizen or resident of
the United States; (ii) a corporation or partnership created or organized in the
United States or under the laws of the United States or of any State thereof;
(iii) an estate or trust described in Section 7701(a)(3) of the Code; or (iv) a
person whose income is includable in gross income for United States federal
income tax purposes regardless of its source. The term "Non-U.S. Holder" means a
beneficial owner of the stock of the Company that is not a U.S. Holder.

TAX CONSEQUENCES TO THE CONTINUATION TO THE COMPANY

The Continuation will constitute a reorganization within the meaning of Section
368(a) of the Code. The Company will recognize no U.S. gain or loss pursuant to
the Continuation provided the Company files certain information with the IRS.

CONSEQUENCES OF THE CONTINUATION TO U.S.  HOLDERS

Generally, U.S. Holders who exchange their shares of the Company pursuant to the
Continuation will recognize no gain or loss on the exchange for United States
federal income tax purposes. Each shareholder's tax basis for the shares of the
Company after the Continuation will equal their tax basis for the shares of the
Company before the Continuation. The holding period for the shares of the
Company after the Continuation will include the holding period of the shares of
the Company before the Continuation provided such shares of Company Stock were
held as a capital asset (as such term is defined under Section 1221 of the Code)
at the effective date of the Continuation.

Cash received as a result of the exercise of dissenter's rights by a U.S. Holder
who dissents from the Continuation (a "Dissenting Shareholder") will be treated
as cash received in redemption of the Dissenting Shareholder's shares of the
Company Stock. A Dissenting Shareholder who, after the Continuation, does not
own (actually or constructively) any capital stock of the Company will generally
recognize gain or loss, measured by the difference between the cash received and
the Dissenting Shareholder's basis in his, her or its Company stock. The gain or
loss should be a capital gain or loss if the Dissenting shareholder holds his,
her or its stock as a capital asset at the effective date of the Continuation.

CONSEQUENCES OF THE CONTINUATION TO NON-U.S. HOLDERS

A Non-U.S. Holder who dissents and receives cash in exchange of his Common
Shares will recognize gain or loss in the manner described above for U.S.
Holders. In general, Non-U.S. Holders will not be subject to United States
federal income tax with respect to capital gains. A Non-U.S. Holder will be
subject to United States federal income tax with respect to capital gains,
however, if (i) such gain is effectively connected with the conduct of a trade
or business within the United States by such holder, or (ii) such holder is an
individual who has been present in the United States for at least 183 days
during the taxable year of the disposition, the Common Stock is a capital asset
and certain other tests are met.

CONSEQUENCES TO NON-U.S.  HOLDERS OF OWNING AND DISPOSING OF COMPANY STOCK

Dividends. In general, dividends paid to a Non-U.S. Holder will be subject to
United States withholding tax at a 30% rate of the gross amount (or a lower rate
prescribed by an applicable income tax treaty) unless the dividends are either
(i) effectively connected with a trade or business carried on by the Non-U.S.
Holder within the United States, or (ii) if certain income tax treaties apply,
attributable to a permanent establishment in the United States maintained by the
Non-U.S. Holder. Dividends effectively connected with such a United States trade
or business or attributable to such a United States permanent establishment
generally will not be subject to United States withholding tax if the Non-U.S.
Holder files


                                     - 59 -
<PAGE>   67
certain forms, including Internal Revenue Service Form 4224, with the payor of
the dividend, and generally will be subject to United States federal income tax
on a net income basis, in the same manner as if the Non-U.S. Holder were a
resident of the United States. A Non-U.S. Holder that is a corporation may be
subject to an additional branch profits tax at a rate of 30% (or such lower rate
as may be specified by an applicable income tax treaty) on the repatriation from
the United States of its "effectively connected earnings and profits," subject
to certain adjustments. Under the income tax treaty between the United States
and Canada, the withholding tax rate on dividends paid to most shareholders who
are resident in Canada will be 15%. To determine the applicability of a tax
treaty providing for a lower rate of withholding under the currently effective
United States Treasury Department regulations (the "Current Regulations"),
dividends paid to an address in a foreign country are presumed to be paid to a
resident of that country absent knowledge to the contrary. Under United States
Treasury Department regulations issued on October 6, 1997 (the "Final
Regulations") generally effective for payments made after December 31, 1998, a
Non-U.S. Holder (including, in certain cases of Non-U.S. Holders that are
fiscally transparent entities, the owner or owners of such entities) will be
required to provide to the payor certain documentation that such Non-U.S. Holder
(or the owner or owners of such fiscally transparent entities) is a foreign
person in order to claim a reduced rate of withholding pursuant to an applicable
income tax treaty.

SALE OF COMMON STOCK. In general, a Non-U.S. Holder will not be subject to
United States federal income tax on any gain realized upon the sale or other
disposition of such holder's shares of Common Stock unless (i) such gain either
is effectively connected with a trade or business carried on by the Non-U.S.
Holder within the United States or, if certain income tax treaties apply, is
attributable to a permanent establishment in the United States maintained by the
Non-U.S. Holder (and in either case, the branch profits tax discussed above may
also apply if the Non-U.S. Holder is a corporation); (ii) the Non-U.S. Holder is
an individual who holds shares of Common Stock as a capital asset and is present
in the United States for at least 183 days during the taxable year of the
disposition, and certain other tests are met; or (iii) the Company is or has
been a "United States real property holding corporation" for federal income tax
purposes and the Non-U.S. Holder owned directly or pursuant to certain
attribution rules at any time during the five-year period ending on the date of
disposition more than 5% of the Company's Common Stock (assuming that Common
Stock is regularly traded on an established securities market). The Company
believes the Company will be a United States real property holding corporation.

ESTATE TAX. Common Stock owned (or treated as owned) by an individual who, at
the time of death, is neither a citizen or a domiciliary of the United States
will be includable in his gross estate for United States federal estate tax
purposes and thus may be subject to United States estate tax, unless an
applicable estate tax treaty provides otherwise.

INFORMATION REPORTING AND BACKUP WITHHOLDING

The Company must report annually to the Internal Revenue Service and to each
shareholder the amount of cash proceeds paid as a result of the Continuation and
dividends paid to, and the tax withheld with respect to, each shareholder. These
reporting requirements apply regardless of whether withholding was reduced or
eliminated by an applicable tax treaty. Copies of these information returns may
also be made available under the provisions of a specific treaty or agreement
with the tax authorities in the country in which a Non-U.S. Holder resides or is
established.

Under the Current Regulations, United States backup withholding tax (which
generally is imposed at the rate of 31% on certain payments to persons that fail
to furnish the information required under the United States information
reporting requirements) and information reporting requirements (other than those
discussed above under "Dividends") generally will not apply to dividends paid on
Common Stock to a Non-U.S. Holder at an address outside the United States.
Backup withholding and information reporting


                                     - 60 -
<PAGE>   68
generally will apply, however, to dividends paid on shares of Common Stock to a
Non-U.S. Holder at an address in the United States, if such holder fails to
establish an exemption or to provide certain other information to the payor.

Under the Current Regulations, the payment of proceeds from the disposition of
Common Stock to or through a United States office of a broker will be subject to
information reporting and backup withholding unless the beneficial owner, under
penalties of perjury, certifies, among other things, its status as a Non-U.S.
Holder or otherwise establishes an exemption. The payment of proceeds from the
disposition of Common Stock to or through a non-U.S. office of a non-U.S. broker
generally will not be subject to backup withholding and information reporting
except as noted below. In the case of proceeds from a disposition of Common
Stock paid to or through a non-U.S. office of a broker that is (i) a United
States person, (ii) a "controlled foreign corporation" for United States federal
income tax purposes, or (iii) a foreign person 50% or more of whose gross income
from certain periods is effectively connected with a United States trade or
business, information reporting (but not backup withholding) will apply unless
the broker has documentary evidence in its files that the owner is a Non-U.S.
Holder (and the broker has no actual knowledge to the contrary).

Under the Final Regulations, the payment of dividends or the payment of proceeds
from the disposition of Common Stock to a Non-U.S. Holder may be subject to
information reporting and backup withholding unless such recipient provides to
the payor certain documentation as to its status as a Non-U.S. Holder or
otherwise establishes an exemption.

Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules from a payment to a Non-U.S. Holder will be refunded or
credited against the Non-U.S. Holder's United States federal income tax
liability, if any, provided that the required information is furnished to the
Internal Revenue Service in a timely manner.

RIGHT OF DISSENT

A dissenting shareholder's right to payment for the Company's shares under the
CBCA are available only if all applicable procedural steps are properly
followed. A dissenting shareholder's failure to vote against the Continuation
will not constitute a waiver of his or her right of dissent. A vote against
Continuation in and of itself will not be deemed to satisfy any notice
requirements under the CBCA. If the number of shareholders exercising
dissenters' rights could adversely affect the Company, the Board of Directors or
officers may abandon the Continuation. The following is a summary of a
shareholder's right to dissent to the Continuance under section 190 of the CBCA.
It is suggested that any holder of shares wishing to avail him or herself to the
right of dissent obtain independent legal advice. The full text of section 190
of the CBCA is set out in Appendix A to this Proxy Statement.

A dissenting shareholder must sent to the Company, at or before the Annual
General Meeting, a written objection to the resolution approving the
Continuation Resolution. The written objection, if mailed, must be sent by
registered mail, addressed to the Company at 600 - 595 Howe Street, Vancouver,
B.C., V6C 2T5. As a result of giving the written objection, the Company will,
within 10 days after the shareholders adopt the Continuation Resolution, send to
each such dissenting shareholder notice that the resolution has been adopted. A
dissenting shareholder shall, within 20 days after receipt of such notice or, if
the shareholder does not receive such notice, within 20 days after the
shareholder learns the Continuation Resolution has been adopted, send to the
Company a written notice containing the shareholder's name and address, the
number and class of shares in respect of which the shareholder dissents, and a
demand for payment of the fair value of such shares ("Demand Notice"). The
dissenting shareholder shall, within 30 days after sending the Demand Notice,
send the certificates representing the shares in respect of which the
shareholders dissents to the Company or its transfer agent. If the dissenting
shareholder fails to send


                                     - 61 -
<PAGE>   69
the share certificate(s) to the Company or its transfer agent within the 30 day
period, the shareholder will have no right to make a claim for payment.

On sending a Demand Notice, a dissenting shareholder ceases to have any rights
as a shareholder of the Company other than the right to be paid the fair value
of the shareholder's shares except where the dissenting shareholder withdraws
his or her Demand Notice before the Company makes an Offer (as described below),
the Company fails to make an Offer and the dissenting shareholder withdraws his
or her notice, or the Directors terminate the application for Continuance. In
such case, the dissenting shareholder's rights as a shareholder are reinstated
as of the date he or she sent the Demand Notice.

The Company shall, no later than 7 days after the later of the day on which the
Continuance is effective or the day the Company receives the Demand Notice, send
to each dissenting shareholder who has sent a Demand Notice a written offer
("Offer") to pay for his or her shares in an amount considered by the Directors
to be the fair value thereof, accompanied by a statement showing how the fair
value was determined, or if there are reasonable grounds for believing that the
Company is or would after the payment be unable to pay its liabilities as they
become due or that the realizable value of the Company's assets would thereby be
less than the aggregate of its liabilities (either such grounds being referred
to as a "Limitation"), a notification that it is unable lawfully to pay
dissenting shareholders for their shares ("Limitation Notice"). Every Offer made
for shares of the same class or series shall be on the same terms.

Subject to any Limitation, the Company shall pay for the shares of a dissenting
shareholder within 10 days after the Offer is accepted. Any such Offer lapses if
the Company does not receive an acceptance within 30 days after the Offer has
been made.

Where the Company fails to make an Offer, or if a dissenting shareholder fails
to accept an Offer, the Company may, within 50 days after the Continuance is
effective or within such further period as a court may allow, apply to a court
to fix a fair value for the shares of any dissenting shareholder. If a Company
fails to apply to a court, a dissenting shareholder may apply to a court for the
same purpose within a further period of 20 days or within such further period as
a court may allow.

A dissenting shareholder, by written notice delivered to the Company within 30
days after receiving a Limitation Notice, may either withdraw his or her notice
of dissent, in which case the Company is deemed to consent to the withdrawal and
the shareholder is reinstated to his or her full rights as a shareholder, or
retain his or her status as a claimant against the Company, to be paid as soon
as the Company is lawfully able to do so or, in a liquidation, to be ranked
subordinate to the rights of creditors of the Company but in priority to its
shareholders.

The fair value of the shares will be determined as of the close of business on
the day before the Continuation Resolution was adopted. The method of
determining "fair value" will vary according to the circumstances of the case.
In reported decisions, the choice of method of valuation has generally been left
to the party appointed by the court or the court itself. It has been held in
previously reported decisions that no discount is to be made to the price of the
shares merely because a minority interest is being purchased. What is to be paid
is the fair value and not the market value. The courts have endeavoured to
determine what is most equitable in the circumstances, including the tax
consequences of the purchase.

If a shareholder elects to dissent and the Continuation Resolution is passed,
and the Company acts on the Continuation Resolution, the procedure which the
Company would propose to follow in order to determine the price to be paid to
the dissenting shareholders with respect to their shares of the Company is as
follows: the Company would attempt to reach a mutually agreed fair value in
direct negotiations


                                     - 62 -
<PAGE>   70
with the dissenting shareholders; if such negotiations were unsuccessful the
Company would propose to appoint a single arbitrator, mutually agreeable to all
of the dissenting shareholders, whose decision would be final and binding on all
parties; in the event that the parties cannot agree upon an acceptable
arbitrator, the matter would be referred to the Supreme Court of British
Columbia. In the event of an arbitration or a court application, all parties
will have the opportunity to present evidence to the arbitrator or court in
order to establish the "fair value". The Company is not required to notify
shareholders of the amount it believes is the "fair value".

The cost of any arbitration or application to the Supreme Court of British
Columbia will be under the discretion of the arbitrator or court. In exercising
such discretion, the Company may be ordered to pay all of the costs incurred by
both the Company and the dissenting shareholders, or the dissenting shareholders
may be ordered to pay all of the costs incurred by the Company and the
dissenting shareholders, or the costs may be divided on some other basis between
the parties. The final decision with respect to the same would be made by the
arbitrator or the court, as the case may be.

A condition to the proposed Merger is that holders of no more than 1% of Optima
shares deliver written demand for appraisal of such shares pursuant to their
dissent rights.

THE CONTINUATION RESOLUTION

Based on the foregoing discussion, the Company's Board of Directors and
Management have approved and believe that it is in the best interests of the
Company and its shareholders to continue the Company into the State of Delaware.
To reduce the franchise fees payable to the Delaware corporate authorities by
the Company following the Continuation, the Company's Board of Directors and
Management believe that it is in the best interest of the Company and its
shareholders to alter the Company's authorized capital from an unlimited number
of common shares of without par value to 75,000,000 shares of Common Stock and
5,000,000 shares of Preferred Stock, each with a par value of $.001 U.S. per
share.

Accordingly, shareholders will be asked at the meeting to consider and if
thought fit, approve a Special Resolution transferring the Company's
jurisdiction of incorporation from the CBCA to Delaware and altering its
authorized share capital in substantially the terms set out below. Management
may elect not to carry out the Continuation if the Merger Resolution is not
approved:

      "Resolved as a Special Resolution that:

      1.    the continuance of the Company's jurisdiction of incorporation from
            Canada to the State of Delaware pursuant to Section 388 of the
            Delaware General corporation Law be approved;

      2.    the Company apply pursuant to Section 188 of the Canada Business
            Corporations Act for authorization to be continued into and be
            registered as a "Corporation" in the State of Delaware pursuant to
            the Delaware General Corporation Law;

      3.    the Company make application to the appropriate authorities in the
            State of Delaware for consent to be domesticated into and registered
            as a "Corporation" pursuant to the Delaware General Corporation Law;

      4.    effective on the date of such continuation under the Delaware
            General Corporation Law, the authorized share capital of the Company
            be altered from an unlimited number of common shares without par
            value to 75,000,000 shares of Common Stock and 5,000,000 shares of
            Preferred Stock, each with a par value of US $.001 per share;


                                     - 63 -
<PAGE>   71
      5.    effective on the date of such continuation as a Corporation under
            the Delaware General Corporation Law, the Company adopt a
            Certificate of Incorporation and Bylaws in substantially the form
            submitted to the shareholders, in substitution for the existing
            Articles and Bylaws of the Company;

      6.    the Board of Directors or officers of the Company be authorized to
            perform such further acts and execute such further documents as may
            be required to give effect to the foregoing; and

      7.    the Directors or officers may, in their sole discretion, elect not
            to act on or carry out this Special Resolution."

THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE CONTINUATION
OF THE COMPANY UNDER THE PROVISIONS OF SECTION 388 OF THE DGCL AND RECOMMENDS
THAT SHAREHOLDERS VOTE FOR THE CONTINUATION INTO THE STATE OF DELAWARE.

NAME CHANGE

GENERAL

In conjunction with the proposed Continuation and Merger, Management proposes to
change the name of the Company to "(diamond)". The approval of the State of
Delaware and the TSE will be required for the name change. For the form of
resolutions proposed, being special resolutions, see "Name Change Shareholder
Resolution" below. Management would like the consent of the shareholders to not
proceed with the name change, notwithstanding the fact that the name change
might be approved by the shareholders, should Management subsequently conclude
that it would not be in the best interests of the Company to proceed.

SHAREHOLDER RESOLUTION

The following special resolution approves the change of name of the Company.

      "Resolved, as a Special Resolution, that the name of the Company be
      changed from Optima Petroleum Corporation to (diamond) and that this name
      be reflected in the Delaware Certificate of Incorporation".

The following special resolution gives management the authority to not proceed
with the name change should it feel it is not necessary. If the Continuation
Resolution and the Merger Resolution are not approved by shareholders, the
Company will not be proceeding with the name change.

      "WHEREAS management proposes to present a special resolution to the
      shareholders at the Meeting with respect to the change of the Company's
      name and may subsequently decide that it is not in the best interests of
      the Company to proceed with such name change;

      Resolved, as a special resolution, that if the directors of the Company
      should resolve after the passing at this Meeting of the special resolution
      relating to the change of the Company's name that it would not be in the
      best interests of the Company to proceed with the name change, then that
      special resolution shall thereupon be rescinded and be of no further
      effect."

ADOPTION OF A NEW STOCK OPTION PLAN

CURRENT STOCK OPTION PLAN

Pursuant to the Company's current stock option plan (the "1996 Plan"), 750,000
common shares have been allotted and reserved for future issuance. As at the
record date, there are outstanding options exercisable into 730,000 common
shares of the Company under the 1996 Plan as well as outstanding options under
the Company's previous plan (the "1995 Plan") exercisable into 52,500 common
shares of Optima. If the Merger is complete, Management proposes to cancel all
of the options currently issued under the 1995 and 1996 Plans and replace them
with options to the following, which are exercisable into 500,000 common shares
of the Company, to be issued under a new stock option plan described below,
having a term of 3 years, granted at the fair market value at the date of the
grant, and vesting immediately on granting.

</TABLE>

(1) The 1995 and 1996 Plans will be cancelled and replaced with the New Plan
upon the completion of the Merger.

In (diamond) of this year, Management of the Company, in conjunction with the
proposed Merger, adopted a new stock option plan (the "New Plan") to be dated
(diamond), 1998. Under the New Plan, 1,800,000 common shares have been allotted
and reserved for future issuance, representing 16% of the currently issued and
outstanding share capital of the Company and 9.8% after giving effect to the
Merger. If the Merger Resolution is not approved by shareholders, Management
will not proceed with the New Plan and proposed grants under the New Plan.
Instead, the 1996 Plan, the 1995 Plan and the presently outstanding options will
remain in place. On the closing of the Merger Transaction, the Company expects
Options to purchase a total of 1,012,300 of Common Stock will be outstanding.
The Options will be granted to the following persons to purchase the number of
shares indicated: (i) options to be granted to Optima optionees (500,000 shares
total) as disclosed above under "Current Stock Option Plan", (ii) Messrs.
Charles Goodson and Alfred Thomas, II (66,000 shares each); (iii) Mr. Ralph
Daigle (60,000 shares); (iv) Mr. Robert Brooksher (38,000 shares); (v) Mr.
Daniel Fournerat (50,000 shares); and (vi) other


                                     - 65 -
<PAGE>   73
employees as a group (232,300 shares). The options in paragraphs (ii) to (vi)
will vest one third on each of December 31, 1989, 1999 and 2000, the option
price will be the fair market value at the date of the grant, and the term of
the Options are 3 years. Options exercisable into 787,700 shares of Common Stock
will be available for further grants.

The Company expects that "insiders" (as defined in the TSE Manual) of the
Company will participate in the Company's New Plan and may acquire the majority
of shares allocated under the New Plan. In addition, the number of shares that
will be reserved for issuance under the New Plan will, together with shares
issued under other existing share compensation arrangements, exceed 10% of the
Company's outstanding issue. "Outstanding issue" is determined on the basis of
the number of shares that are outstanding immediately prior to the share
issuance in question, excluding shares issued pursuant to share compensation
arrangements over the preceding one-year period and outstanding share capital.
For these reasons, the TSE requires that the Company ask the shareholders to
approve the New Plan (see "Shareholder Approval" below).

The following is a discussion of the proposed New Plan.

NEW STOCK OPTION PLAN

GENERAL. The objectives of the New Plan are to attract and retain selected key
employees, consultants and directors, encourage their commitment, motivate their
superior performance, facilitate their obtaining ownership interests in the
Company (aligning their personal interests to those of the Company's
stockholders) and enable them to share in the long-term growth and success of
the Company.

SHARES SUBJECT TO NEW PLAN. Under the New Plan, the Company may issue Incentive
Awards (as defined below) covering 1.8 million shares of Common Stock. No more
than 1.8 million shares of Common Stock will be available for ISOs (as defined
below). As of the closing of the Merger Transaction, options covering 1,012,300
shares of Common Stock will be outstanding and 787,700 shares of Common Stock
then will be available for subsequent Incentive Awards. The number of securities
available under the New Plan and outstanding Incentive Awards are subject to
adjustments to prevent enlargement or dilution of rights resulting from stock
dividends, stock splits, recapitalizations or similar transactions or resulting
from a change in applicable laws or other circumstances.

ADMINISTRATION. The New Plan will be administered by the compensation committee
of the Board of Directors (the "Compensation Committee"). Following the Merger
Transaction, the Compensation Committee will consist solely of directors each of
whom is (i) an "outside director" under Section 162(m) of the Internal Revenue
Code of 1986, as amended (the "Code"), and (ii) a "non-employee director" under
Rule 16b-3 under the Exchange Act. The Compensation Committee may delegate to
the chief executive officer or other senior officers of the Company its duties
under the New Plan, except with respect to any authority to grant Incentive
Awards or take other action with respect to persons who are subject to Section
16 of the Exchange Act or Section 162(m) of the Code. In the case of an
Incentive Award to an outside director, the Board of Directors shall act as the
Compensation Committee. Subject to the express provisions of the New Plan, the
Compensation Committee is authorized to, among other things, select grantees
under the New Plan and determine the size, duration and type, as well as the
other terms and conditions (which need not be identical), of each Incentive
Award. The Compensation Committee also construes and interprets the New Plan and
any related agreements. All determinations and decisions of the Compensation
Committee are final, conclusive and binding on all parties. The Company will
indemnify members of the Compensation Committee against any damage, loss,
liability, cost or expenses arising in connection with any claim, action, suit
or proceeding by reason of any action taken or failure to act under the New
Plan, except for any such act or omission constituting wilful misconduct or
gross negligence.


                                     - 66 -
<PAGE>   74
ELIGIBILITY. Key employees, including officers (whether or not they are
directors), and consultants of the Company and outside directors are eligible to
participate in the New Plan. A key employee generally is any employee of the
Company who, in the opinion of the Compensation Committee, is in a position to
contribute materially to the growth and development and to the financial success
of the Company.

TYPES OF INCENTIVE AWARDS. Under the New Plan, the Compensation Committee may
grant (i) incentive stock options ("ISOs"), as defined in Section 422 of the
Code, (ii) "nonstatutory" stock options ("NSOs"), (iii) stock appreciation
rights ("SARs"), (iv) shares of restricted stock, (v) performance units and
performance shares, (vi) other stock-based awards, and (vii) supplemental
payments dedicated to the payment of income taxes (collectively, "Incentive
Awards"). ISOs and NSOs are sometimes referred to collectively herein as
"Options." The terms of each Incentive Award will be reflected in an agreement
(the "Incentive Agreement") between the Company and the participant.

OPTIONS. Generally, Options must be exercised within 10 years of the grant date.
ISOs may be granted only to employees, and the exercise price of each ISO may
not be less than 100% of the fair market value of a share of Common Stock on the
date of grant. The Compensation Committee will have the discretion to determine
the exercise price of each NSO granted under the New Plan. To the extent that
the aggregate fair market value of shares of Common Stock with respect to which
ISOs are exercisable for the first time by any employee during any calendar year
exceeds US$100,000, such options must be treated as NSOs.

The exercise price of each Option is payable in cash or, in the discretion of
the Compensation Committee, by the delivery of shares of Common Stock owned by
the Optionee or the withholding of shares that would otherwise be acquired on
the exercise of the Option or by any combination of the foregoing.

An employee will not recognize any income for federal income tax purposes at the
time an ISO is granted, nor on the qualified exercise of an ISO, and will
recognize capital gain or loss (as applicable) upon the subsequent sale of
shares acquired in a qualified exercise. The exercise of an ISO is qualified if
a participant does not dispose of the shares acquired by such exercise within
two years after the ISO grant date and one year after such exercise. The Company
is not entitled to a tax deduction as a result of the grant or qualified
exercise of an ISO.

An optionee will not recognize any income for federal income tax purposes, nor
will the Company be entitled to a deduction, at the time an NSO is granted.
However, when an NSO is exercised, the optionee will recognize ordinary income
in an amount equal to the difference between the fair market value of the shares
received and the exercise price of the NSO, and the Company will generally
recognize a tax deduction in the same amount at the same time.

The foregoing federal income tax information is a summary only, does not purport
to be a complete statement of the relevant provisions of the Code and does not
address the effect of any state of local taxes.

SARS. Upon exercise of an SAR, the holder will receive cash, shares of Common
Stock or a combination thereof, as specified in the related Incentive Agreement,
the aggregate value of which equals the amount by which the fair market value
per share of the Common Stock on the date of exercise exceeds the exercise price
of the SAR, multiplied by the number of shares underlying the exercised portion
of the SAR. An SAR may be granted in tandem with or independently of an NSO.
SARs will be subject to such terms and conditions and will be exercisable at
such times as determined by the Compensation Committee, provided, that the
exercise price per share must equal at least 100% of the fair market value of a
share of a Common Stock on the date of grant. The value of an SAR may be paid in
cash, shares of Common Stock or a combination thereof, as determined by the
Compensation Committee.


                                     - 67 -
<PAGE>   75
RESTRICTED STOCK. Restricted stock may be subject to substantial risk of
forfeiture, a restriction on transferability or rights of repurchase or first
refusal of the Company, as determined by the Compensation Committee. Unless
otherwise determined by the Compensation Committee, during the period of
restriction, the grantee will have all other rights of a stockholder, including
the right to vote the shares and receive the dividends paid thereon.

PERFORMANCE UNITS AND PERFORMANCE SHARES. Performance units and performance
shares may be granted only to employees and consultants. For each performance
period (to be determined by the Compensation Committee), the Compensation
Committee will establish specific financial or non-financial performance
objectives, the number of performance units or performance shares and their
contingent values, which values may vary depending on the degree to which such
objectives are met.

OTHER STOCK-BASED AWARDS. Other stock-based awards are awards denominated or
payable in, valued in whole or in part by reference to or otherwise related to
shares of Common Stock. Subject to the terms of the New Plan, the Compensation
Committee may determine any terms and conditions of other stock-based awards,
provided that, in general, the amount of consideration to be received by the
Company shall be either (i) no consideration other than services actually
rendered or to be rendered (in the case of the issuance of shares) or (ii) in
the case of an award in the nature of a purchase right, consideration (other
than services rendered) at least equal to 50% of the fair market value of the
shares covered by such grant on the date of grant. Payment or settlement of
other stock-based awards will be in shares of Common Stock or in other
consideration related to such shares.

SUPPLEMENTAL PAYMENTS FOR TAXES. The Compensation Committee may grant, in
connection with an Incentive Award (except for ISOs), a supplemental payment in
an amount not to exceed the amount necessary to pay the federal and state income
taxes payable by the grantee with respect to the Incentive Award and the receipt
of such supplemental payment.

OTHER TAX CONSIDERATIONS. Upon accelerated exercisability of Options and
accelerated lapsing of restrictions upon restricted stock or other Incentive
Awards in connection with a Change in Control (as defined in the New Plan),
certain amounts associated with such Incentive Awards could, depending upon the
individual circumstances of the participant, constitute "excess parachute
payments" under Section 280G of the Code, thereby subjecting the participant to
a 20% excise tax on those payments and denying the Company a deduction with
respect thereto. The limit on the deductibility of compensation under Section
162(m) of the Code is also reduced by the amount of any excess parachute
payments. Whether amounts constitute excess parachute payments depends upon,
among other things, the value of the Incentive Awards accelerated and the past
compensation of the participant.

Taxable compensation earned by executive officers who are subject to Section
162(m) of the Code in respect of Incentive Awards is subject to certain
limitations set forth in the New Plan generally intended to satisfy the
requirements for "qualified performance-based compensation," but no assurance
can be given that the Company will be able to satisfy these requirements in all
cases, and the Company may, in its sole discretion, determine in one or more
cases that it is in its best interest not to satisfy these requirements even if
it is able to do so.

TERMINATION OF EMPLOYMENT AND CHANGE IN CONTROL. Except as otherwise provided in
the applicable Incentive Agreement, if a participant's employment or other
service with the Company (or its subsidiaries) is terminated (i) other than due
to his death, Disability, Retirement or for Cause (each capitalized term as
defined in the New Plan), his then exercisable Options will remain exercisable
for 90 days after such termination, (ii) by reason of Disability or death, his
then exercisable Options will remain exercisable for one year following such
termination, (iii) due to his retirement, his then exercisable Options will
remain exercisable for one year (except for ISOs, which will remain exercisable
for one


                                     - 68 -
<PAGE>   76
year), or (iv) for Cause, all his Options will expire at the commencement of
business on the date of such termination.

Upon a Change in Control of the Company, any restrictions on restricted stock
and other stock-based awards will be deemed satisfied, all outstanding Options
and SARs will become immediately exercisable and all the performance shares and
units and any other stock-based awards will be fully vested and deemed earned in
full. These provisions could in some circumstances have the effect of an
"anti-takeover" defence because, as a result of these provisions, a Change in
Control of the Company could be more difficult or costly.

INCENTIVE AWARDS NONTRANSFERABLE. No Incentive Award may be assigned, sold or
otherwise transferred by a participant, other than by will or by the laws of
descent and distribution, or be subject to any encumbrance, pledge, lien,
assignment or charge. An Incentive Award may be exercised during the
participant's lifetime only by the participant or the participant's legal
guardian.

AMENDMENT AND TERMINATION. The Company's board of directors may amend or
terminate the New Plan at any time, except that the New Plan may not be modified
or amended, without stockholder approval, if such amendment would (i) increase
the number of shares of Common Stock which may be issued thereunder, except in
connection with a recapitalization of the Common Stock, (ii) amend the
eligibility requirements for employees to purchase Common Stock under the New
Plan, (iii) increase the maximum limits on Incentive Awards that may be issued
to executive officers who are subject to Section 162(m) of the Code, (iv) extend
the term of the New Plan or (v) decrease the authority granted to the
Compensation Committee under the New Plan in contravention of Rule 16b-3 under
the Exchange Act. No termination or amendment of the New Plan shall adversely
affect in any material way any outstanding Incentive Award previously granted to
a participant without his consent.

OTHER SHARE COMPENSATION ARRANGEMENTS

FEES FOR OUTSIDE DIRECTORS. At the annual general meeting of May 24, 1996,
shareholders approved the reservation of 2,500 common shares for issuance to
outside directors for their attendance at directors' meetings. These shares
would be issued at the rate of 138 common shares per outside director per
directors' meeting at the deemed price of $3.63 per share. As at the record
date, 1,380 common shares have been issued.

SHAREHOLDER APPROVAL

As described above, the cancellation of the 1995 and 1996 Plans and the adoption
of the New Plan must be approved generally by the shareholders of the Company.
The rules of the TSE further provide that where a proposed share compensation
arrangement, together with all of a company's other previously established or
proposed share compensation arrangements, could result, at any time, in:

(a)   the number of shares reserved for issuance pursuant to stock options
      granted to insiders exceeding 10% of the company's outstanding issue;

(b)   the issuance to insiders, within a one-year period, of a number of shares
      exceeding 10% of the company's outstanding issue; or

(c)   the issuance to any one insider and such insider's associates, within a
      one-year period, of a number of shares exceeding 5% of the company's
      outstanding issue;


                                     - 69 -
<PAGE>   77
then the share compensation arrangement must be approved by a "disinterested
shareholder vote", meaning a majority of the votes cast at the shareholders'
meeting other than votes attaching to securities beneficially owned by insiders
to whom shares may be issued pursuant to the share compensation arrangement and
their associates. As disclosed above, the Company proposes to issue options to
current insiders and nominees for directors exercisable into 680,000 common
shares of the Company, representing 6.7% of the Company's outstanding issue and
may issue more in the future. Accordingly, the Company is seeking disinterested
shareholders' approval, with the directors and the Amex nominees and their
associates abstaining, to the New Plan. As at the record date, the directors and
the Amex nominees and their associates beneficially own [diamond] common shares
of Optima. The Company will only seek disinterested shareholders' approval to
the New Plan if the Continuation Resolution and the Merger Resolution are
approved (see "Continuation into the State of Delaware" and "The Merger
Transaction").

"IT IS HEREBY RESOLVED THAT (with Robert L. Hodgkinson, William C. Leuschner,
Ronald P. Bourgeois, Emile Stehelin, Martin Abbott, Ralph J. Daigle, Charles T.
Goodson, Alfred J. Thomas II, Robert R. Brooksher and Daniel G. Fournerat and
their associates abstaining):

1.    the Company's current Stock Option Plan (the "1996 Plan") dated April 10,
      1996 and Stock Option Plan of 1995 (the "1995 Plan") be replaced by a new
      Stock Option Plan ("New Plan") to be dated [diamond], 1998 and the New
      Plan be adopted and approved;

2.    all of the options outstanding under the 1996 Plan and 1995 Plan be
      cancelled and certain option holders (five of whom are insiders of the
      Company) under the 1996 Plan and 1995 Plan be issued new options under the
      New Plan, which options shall be exercisable into an aggregate of 500,000
      common shares of the Company;

3.    the Company be authorized to grant stock options pursuant and subject to
      the terms and conditions of the New Plan entitling the option holders to
      purchase up to 1,800,000 common shares of the Company;

4.    the board of directors, by resolution, be authorized to make such
      amendments to the New Plan, from time to time, as may, in its discretion,
      be considered appropriate, provided always that such amendments be subject
      to the approval of all applicable regulatory authorities;

5.    any one director or senior officer of the Company be and he is hereby
      authorized and directed to perform all such acts, deeds and things and
      execute, under the seal of the Company if applicable, all such documents
      and other writings as may be required to give effect to the true intent of
      this resolution."

By way of summary, the total number of shares that will be reserved for issuance
pursuant to the share compensation arrangements discussed above, the New Plan
and the existing stock options will be as follows:

<S>                                              <C>
      Share-compensation to directors                1,120 common shares

      Total:                                     1,801,120 common shares
</TABLE>

As of the record date, the Company had a total of 11,002,346 common shares
issued and outstanding. The foregoing 1,801,120 common shares reserved for
issuance will represent 16% of the Company's currently issued and outstanding
share capital and 9.8% after giving effect to the Merger.

ACQUISITION OF 5% WORKING INTEREST IN THE VALENTINE PROSPECT

GENERAL

Pursuant to an agreement dated April (diamond), 1998, Optima agreed to acquire a
5% working interest in the Valentine prospect from Colima Oil Company ("Colima")
as to 2% and 7804 Yukon, Inc. ("Yukon") as to 3% (the "Acquisition"). The total
purchase price for the 5% working interest is US$675,300 (US$270,120 to Colima
and US$405,180 to Yukon). US$325,300 of the purchase price will be paid by way
of common shares of Optima at the deemed price of US$1.6265 per share. The
shares will be subject to a one year hold period pursuant to Rule 144 of the
U.S. Securities Act of 1933.

VALENTINE PROSPECT

See "The Plan and Agreement of Merger - Information concerning the Company
Principal Production Properties" for a description of the Valentine prospect.

SHAREHOLDER APPROVAL

Yukon is owned by Emile Stehelin, a director of Optima, as to 51% and Robert
Hodgkinson, President and director of Optima, as to 49%. Colima is wholly owned
by William Leuschner, Chairman of Optima. As such, the Acquisition is a
non-arms' length transaction.

The TSE requires, as a condition of its acceptance of this Acquisition,
"disinterested shareholder approval", meaning a majority of the votes cast at
the shareholders' meeting other than votes attaching to securities beneficially
owned by Yukon, Colima and by any of their respective individuals, associates,
affiliates and insiders. As at the record date, Yukon, Colima and their
individuals, associates, affiliates and insiders beneficially own [diamond]
common shares of the Company. Shareholders (with Yukon, Colima, and their
individuals, associates, affiliates and insiders abstaining) will be asked to
approve the resolutions below.

"IT IS HEREBY RESOLVED THAT (with Colima Oil Company, 7804 Yukon, Inc. and
their individuals, associates, affiliates and insiders abstaining):

1.    the acquisition of a 5% working interest ("Acquisition") in the
      Valentine property from Colima Oil Company ("Colima") as to 2% and 7804
      Yukon, Inc. ("Yukon") as to 3% be approved;

2.    the aggregate purchase price of US$675,300 payable to Yukon as to
      US$405,180 and Colima as to US$270,120, US$325,300 of which will be
      payable in common shares of Optima at the deemed price of US$1.6265 per
      share for an aggregate of 200,000 common shares be approved;

3.    the board of directors, by resolution, be authorized to make such
      amendments to the Acquisition Agreement, from time to time, as may, in its
      discretion, be considered appropriate, provided always that such
      amendments be subject to the approval of all applicable regulatory
      authorities;

4.    any one Director or Senior Officer of the Company be and he is hereby
      authorized and directed to perform all such acts, deeds and things and
      execute, under the seal of the Company if applicable, all such documents

                 DATE FOR SUBMISSION OF SHAREHOLDER PROPOSALS

                             SECTION 190 OF THE CBCA

190.  RIGHT TO DISSENT

(1) Subject to sections 191 and 241, a holder of shares of any class of a
corporation may dissent if the corporation is subject to an order under
paragraph 192(4)(d) that affects the holder or if the corporation resolves to

      (a)   amend its articles under section 173 or 174 to add, change or remove
            any provisions restricting or constraining the issue, transfer or
            ownership of shares of that class;

      (b)   amend its articles under section 173 to add, change or remove any
            restriction on the business or businesses that the corporation may
            carry on;

      (c)   amalgamate otherwise than under section 184; (1994, c. 24, s. 23.)

      (d)   be continued under section 188; or (1994, c. 24, s. 23.)

      (e)   sell, lease or exchange all or substantially all its property under
            subsection 189(3).

(2) Further right. A holder of shares of any class or series of shares entitled
to vote under section 176 may dissent if the corporation resolves to amend its
articles in a manner described in that section.

(3) Payment for shares. In addition to any other right he may have, but subject
to subsection (26), a shareholder who complies with this section is entitled,
when the action approved by the resolution from which he dissents or an order
made under subsection 192(4) becomes effective, to be paid by the corporation
the fair value of the shares held by him in respect of which he dissents,
determined as of the close of business on the day before the resolution was
adopted or the order was made.

(4) No partial dissent. A dissenting shareholder may only claim under this
section with respect to all the shares of a class held by him on behalf of any
one beneficial owner and registered in the name of the dissenting shareholder.

(5) Objection. A dissenting shareholder shall send to the corporation, at or
before any meeting of shareholders at which a resolution referred to in
subsection (1) or (2) is to be voted on, a written objection to the resolution,
unless the corporation did not give notice to the shareholder of the purpose of
the meeting and of his right to dissent.

(6) Notice of resolution. The corporation shall, within ten days after the
shareholders adopt the resolution, send to each shareholder who has filed the
objection referred to in subsection (5) notice that the resolution has been
adopted, but such notice is not required to be sent to any shareholder who voted
for the resolution or who has withdrawn his objection.

(7) Demand for payment. A dissenting shareholder shall, within twenty days after
he receives a notice under subsection (6) or, if he does not receive such
notice, within twenty days after he learns that the resolution has been adopted,
send to the corporation a written notice containing

      (a)   his name and address;

      (b)   the number and class of shares in respect of which he dissents; and

      (c)   a demand for payment of the fair value of such shares.

(8) Share certificate. A dissenting shareholder shall, within thirty days after
sending a notice under subsection (7), send the certificates representing the
shares in respect of which he dissents to the corporation or its transfer agent.
<PAGE>   81
(9) Forfeiture. A dissenting shareholder who fails to comply with subsection (8)
has no right to make a claim under this section.

(10) Endorsing certificate. A corporation or its transfer agent shall endorse on
any share certificate received under subsection (8) a notice that the holder is
a dissenting shareholder under this section and shall forthwith return the share
certificates to the dissenting shareholder.

(11) Suspension of rights. On sending a notice under subsection (7), a
dissenting shareholder ceases to have any rights as a shareholder other than the
right to be paid the fair value of his shares as determined under this section
except where

      (a)   the dissenting shareholder withdraws his notice before the
            corporation makes an offer under subsection (12),

      (b)   the corporation fails to make an offer in accordance with subsection
            (12) and the dissenting shareholder withdraws his notice, or

      (c)   the directors revoke a resolution to amend the articles under
            subsection 173(2) or 174(5), terminate an amalgamation agreement
            under subsection 183(6) or an application for continuance under
            subsection 188(6), or abandon a sale, lease or exchange under
            subsection 189(9).

in which case his rights as a shareholder are reinstated as of the date he sent
the notice referred to in subsection (7).

(12) Offer to pay. A corporation shall, not later than seven days after the
later of the day on which the action approved by the resolution is effective or
the day the corporation received the notice referred to in subsection (7), send
to each dissenting shareholder who has sent such notice

      (a)   a written offer to pay for his shares in an amount considered by the
            directors of the corporation to be the fair value thereof,
            accompanied by a statement showing how the fair value was
            determined; or

      (b)   if subsection (26) applies, a notification that it is unable
            lawfully to pay dissenting shareholders for their shares.

(13) Same terms. Every offer made under subsection (12) for shares of the same
class or series shall be on the same terms.

(14) Payment. Subject to subsection (26), a corporation shall pay for the shares
of a dissenting shareholder within ten days after an offer made under subsection
(12) has been accepted, but any such offer lapses if the corporation does not
receive an acceptance thereof within thirty days after the offer has been made.

(15) Corporation may apply to court. Where a corporation fails to make an offer
under subsection (12), or if a dissenting shareholder fails to accept an offer,
the corporation may, within fifty days after the action approved by the
resolution is effective or within such further period as a court may allow,
apply to a court to fix a fair value for the shares of any dissenting
shareholder.

(16) Shareholder application to court. If a corporation fails to apply to a
court under subsection (15), a dissenting shareholder may apply to a court for
the same purpose within a further period of twenty days or within such further
period as a court may allow.

(17) Venue. An application under subsection (15) or (16) shall be made to a
court having jurisdiction in the place where the corporation has its registered
office or in the province where the dissenting shareholder resides if the
corporation carries on business in that province.

(18) No security for costs. A dissenting shareholder is not required to give
security for costs in an application made under subsection (15) or (16).


                                     - 2 -
<PAGE>   82
(19)  Parties.  On an application to a court under subsection (15) or (16),

      (a)   all dissenting shareholders whose shares have not been purchased by
            the corporation shall be joined as parties and are bound by the
            decision of the court; and

      (b)   the corporation shall notify each affected dissenting shareholder of
            the date, place and consequences of the application and of his right
            to appear and be heard in person or by counsel.

(20) Powers of court. On an application to a court under subsection (15) or
(16), the court may determine whether any other person is a dissenting
shareholder who should be joined as a party, and the court shall then fix a fair
value for the shares of all dissenting shareholders.

(21) Appraisers. A court may in its discretion appoint one or more appraisers to
assist the court to fix a fair value for the shares of the dissenting
shareholders.

(22) Final order. The final order of a court shall be rendered against the
corporation in favour of each dissenting shareholder and for the amount of his
shares as fixed by the court.

(23) Interest. A court may in its discretion allow a reasonable rate of interest
on the amount payable to each dissenting shareholder from the date the action
approved by the resolution is effective until the date of payment.

(24) Notice that subsection (26) applies. If subsection (26) applies, the
corporation shall, within ten days after the pronouncement of an order under
subsection (22), notify each dissenting shareholder that it is unable lawfully
to pay dissenting shareholders for their shares.

(25) Effect where subsection (26) applies. If subsection (26) applies, a
dissenting shareholder, by written notice delivered to the corporation within
thirty days after receiving a notice under subsection (24), may

      (a)   withdraw his notice of dissent, in which case the corporation is
            deemed to consent to the withdrawal and the shareholder is
            reinstated to his full rights as a shareholder; or

      (b)   retain a status as a claimant against the corporation, to be paid as
            soon as the corporation is lawfully able to do so or, in a
            liquidation, to be ranked subordinate to the rights of creditors of
            the corporation but in priority to its shareholders.

(26) Limitation. A corporation shall not make a payment to a dissenting
shareholder under this section if there are reasonable grounds for believing
that

      (a)   the corporation is or would after the payment be unable to pay
            its liabilities as they become due; or

      (b)   the realizable value of the corporation's assets would thereby be
            less than the aggregate of its liabilities.

                                FAIRNESS OPINION

                 [LETTERHEAD OF R P & C INTERNATIONAL, INC.]

March 7, 1998

The Board of Directors
Optima Petroleum Corporation
600-595 Howe Street
Vancouver, British Columbia
Canada  V6C 2T5

Members of the Board:

You have requested our opinion as to the fairness, from a financial point of
view, to the holders of the common stock of Optima Petroleum Corporation
("Optima") of the consideration ("Merger Consideration") to be paid pursuant to
the terms and subject to the conditions set forth in the Plan and Agreement of
Merger, dated as of February 11, 1998 (the "Merger Agreement"), by and among
Optima Petroleum Corporation, Optima Energy (U.S.) Corporation and Goodson
Exploration Company, NAB Financial, L.L.C., Dexco Energy, Inc. (collectively the
"Target Corporations"), and American Explorer, L.L.C. ("American Explorer").
Under the terms of the Merger Agreement, an aggregate of 7,335,001 shares of
Optima and 1,667,001 Units of Contingent Interests shall be issued to the
shareholders of the Target Corporations. (The transaction contemplated above
here and after referred to as the "Merger".)

In arriving at our opinion, we reviewed the Merger Agreement. Additionally, we
reviewed the following documents of Optima Petroleum Corporation: Reserve
Reports prepared by Ryder Scott Company and LaRoche Petroleum Consultants, dated
as of December 31, 1997; Annual Reports for 1994, 1995 and 1996; Form 10-K's for
the years 1994, 1995 and 1996; Form 10-Q's for the periods ending September 30,
1997, June 30, 1997 and March 31, 1997; management's Letter to KPMG March 26,
1997, Draft Consolidated Financial Statements for the years ended December 31,
1997, 1996 and 1995, the Articles of Incorporation and By Laws of Optima, Form
20-F Amendment No. 1, December 31, 1994, and a valuation of exploration
prospects and exploratory leads in which Optima owns an interest, prepared by
LaRoche Petroleum Consultants.

We also reviewed the following documents of American Explorer, L.L.C.: Reserve
Reports prepared by DOR Engineering, Inc. dated as of December 31, 1997;
unaudited Statement of Assets, Liabilities & Members' Capital as of September
30, 1997 and December 31, 1996; Statement of Assets, Liabilities & Members'
Capital as of December 31, 1997 and December 31, 1996, marked Tentative For
Discussion Purposes Only; Operating Agreement; the Credit Agreement Between
American Explorer, L.L.C. and Compass Bank dated October 16, 1997, and a
valuation of exploration prospects and exploratory leads in which American
Explorer owns an interest, prepared by LaRoche Petroleum Consultants (addressed
to Mr. William Leuschner, Chairman of Optima).

We met with certain members of management of American Explorer at their offices
in Lafayette, Louisiana, where we reviewed and discussed the significant oil and
gas prospects of American Explorer with management. We held discussions with
certain senior officers of Optima and certain senior officers of American
Explorer concerning the businesses, operations and prospects of Optima and
American Explorer. We discussed the strategy of Optima with its management, and
the methodology employed in determining an exchange ratio of Optima stock for
the stock of American Explorer.
<PAGE>   84
We examined certain publicly available business and financial information
relating to Optima, as well as certain financial forecasts and other information
and data for Optima and American Explorer, which were provided to or otherwise
discussed with us by the respective managements of Optima and American Explorer,
including information relating to certain strategic implications and operational
benefits anticipated to result from the Merger. We reviewed the financial terms
of the Merger as set forth in the Merger Agreement in relation to, among other
things: current and historical market prices and trading volumes of Optima
Common Stock, and the capitalization and financial condition of Optima and
American Explorer.

We considered, to the extent publicly available, the financial terms of other
transactions recently effected which we considered relevant in evaluating the
Merger and analyzed certain financial, stock market and other publicly available
information relating to the businesses of other companies whose operations we
considered relevant in evaluating those of Optima and American Explorer. We also
evaluated the potential pro forma financial impact of the Merger on Optima. In
addition to the foregoing, we conducted such other analyses and examinations and
considered such other financial, economic and market criteria as we deemed
appropriate in arriving at our opinion.

In rendering our opinion, we have assumed and relied, without independent
verification, upon the accuracy and completeness of all financial and other
information and data publicly available or furnished to or otherwise reviewed by
or discussed with us. With respect to financial forecasts and other information
and data provided to or otherwise reviewed by or discussed with us, we have been
advised by the managements of Optima and American Explorer that such forecasts
and other information and data were reasonably prepared on bases reflecting the
best currently available estimates and judgments of the managements of Optima
and American Explorer as to the future financial performance of Optima and
American Explorer and the strategic implications and operational benefits
anticipated to result from the Merger.

We are not expressing any opinion as to what the value of the shares actually
will be when issued, or the price at which the shares will trade or otherwise be
transferable subsequent to the Merger. We have not made an independent
evaluation or appraisal of the assets or liabilities (contingent or otherwise)
of either American Explorer or Optima nor have we made any physical inspection
of the properties or assets of either company. Our opinion is necessarily based
upon information available to us, and financial, stock market and other
conditions and circumstances existing and disclosed to us, as of the date
hereof.

We have received a fee in connection with the delivery of this opinion. We have
had no relationship with Optima or American Explorer or their respective
affiliates in the past.

Our advisory services and the opinion expressed herein are provided for the
information of the Board of Directors of Optima in its evaluation of the
proposed Merger, and our opinion is not intended to be and does not constitute a
recommendation to any stockholder as to how such stockholder should vote on the
proposed Merger. Our opinion may not be published or otherwise used or referred
to, nor shall any public reference to R P & C International, Inc. be made,
without our prior written consent.

Based upon and subject to the following, our experience as investment bankers,
our work as described above and other factors we deemed relevant, we are of the
opinion that, as of the date hereof, the Merger Consideration is fair from a
financial point of view to the holders of Optima Common Stock.

Very truly yours,

R P & C INTERNATIONAL, INC.

        The nature of the business or purposes to be conducted or promoted is to

                                   ARTICLE IV

                            AUTHORIZED CAPITAL STOCK

        The aggregate number of shares of all classes of stock which the
Corporation shall have authority to issue is 80,000,000 shares, consisting of:
(i) 75,000,000 shares of common stock, par value $.001 per share (the "Common
Stock"), and (ii) 5,000,000 shares of preferred stock, par value $.001 per share
(the "Preferred Stock"). Shares of any class of capital stock of the Corporation
may be issued for such consideration and for such corporate purposes as the
Board of Directors of the Corporation (the "Board of Directors") may from time
to time determine. Each share of Common Stock shall be entitled to one vote.

        A. Preferred Stock. The Preferred Stock may be divided into and issued
from time to time in one or more series as may be fixed and determined by the
Board of Directors. The relative rights and preferences of the Preferred Stock
of each series shall be such as shall be stated in any resolution or resolutions
adopted by the Board of Directors setting forth the designation of the series
and fixing and 
<PAGE>   86
determining the relative rights and preferences thereof (a "Directors'
Resolution"). The Board of Directors is hereby authorized to fix and determine
the powers, designations, preferences, and relative, participating, optional or
other rights, including, without limitation, voting powers, full or limited,
preferential rights to receive dividends or assets upon liquidation, rights of
conversion or exchange into Common Stock, Preferred Stock of any series or other
securities, any right of the Corporation to exchange or convert shares into

qualifications, limitations or restrictions thereof, if any, all as shall be
stated in a Directors' Resolution, and the shares of Preferred Stock or any
series thereof may have full or limited voting powers, or be without voting
powers, all as shall be stated in a Directors' Resolution. Except where
otherwise set forth in the Directors' Resolution providing for the issuance of
any series of Preferred Stock, the number of shares comprising such series may
be increased or decreased (but not below the number of shares then outstanding)
from time to time by like action of the Board of Directors. The shares of
Preferred Stock of any one series shall be identical with the other shares in
the same series in all respects except as to the dates from and after which
dividends thereon shall cumulate, if cumulative.

        B. Reacquired Shares of Preferred Stock. Shares of any series of any
Preferred Stock that have been redeemed (whether through the operation of a
sinking fund or otherwise), purchased by the Corporation, or which, if
convertible or exchangeable, have been converted into, or exchanged for, shares
of stock of any other class or classes or any evidences of indebtedness shall
have the status of authorized and unissued shares of Preferred Stock and may be
reissued as a part of the series of which they were originally a part or may be
reclassified and reissued as part of a new series of Preferred Stock or as part
of any other series of Preferred Stock, all subject to the conditions or
restrictions on issuance set forth in the Directors' Resolution providing for
the issuance of any series of Preferred Stock and to any filing required by law.

        C. Increase in Authorized Preferred Stock. The number of authorized
shares of Preferred Stock may be increased or decreased by the affirmative vote
of the holders of a majority of the stock of the Corporation entitled to vote
without the separate vote of holders of Preferred Stock as a class.


                                    ARTICLE V

                                    EXISTENCE

        No stockholder shall be entitled, as a matter of right, to subscribe for
or acquire additional, unissued or treasury shares of any class of capital stock
of the Corporation whether now or hereafter authorized, or any bonds, debentures
or other securities convertible into, or carrying a right to subscribe to or

        At each election of directors, every stockholder entitled to vote at
such election shall have the right to vote in person or by proxy the number of
shares owned by him for as many persons as there are directors to be elected and
for whose election he has a right to vote. No stockholder shall have the right
to cumulate his votes in any election of directors.



                                  ARTICLE VIII

                     NO STOCKHOLDER ACTION WITHOUT A MEETING

        Except as otherwise required by law, any action required or permitted to
be taken by the stockholders of the Corporation must be effected at an annual or
special meeting of stockholders of the Corporation and may not be effected by
any consent in writing by such stockholders. A special meeting of stockholders
of the Corporation may be called only by the Chairman of the Board, the Chief
Executive Officer, the President or the Board of Directors by the written order
of a majority of the entire Board of Directors, and not by the stockholders
except as otherwise provided by law or the Bylaws of the Corporation ("Bylaws").



                                   ARTICLE IX

                               BOARD OF DIRECTORS

        The business and affairs of the Corporation shall be managed by or under
the direction of the Board of Directors. In addition to the authority and powers
conferred upon the Board of Directors by the DGCL or by the other provisions of
this Certificate of Incorporation (this "Certificate of Incorporation"), the
Board of Directors is hereby authorized and empowered to exercise all such
powers and do all such acts and things as may be exercised or done by the
Corporation, subject to the provisions of the DGCL, this Certificate of
Incorporation and the Bylaws; provided, however, that no Bylaws hereafter
adopted by the stockholders of the Corporation, or any amendments thereto, shall
invalidate any prior act of the Board of Directors that would have been valid if
such Bylaws or amendment had not been adopted.

        A. Number, Election and Terms of Directors. The number of directors
which shall constitute the whole Board of Directors shall be fixed from time to
time by a majority of the directors then in office. Each director shall hold
office until the next annual meeting and shall serve until his successor shall
have been duly elected and qualified or until his earlier death, resignation or
removal. Election of directors need not be by written ballot unless the Bylaws
of the Corporation shall so provide.

        B. Removal of Directors. No director of the Corporation shall be removed
from office as a director by vote or other action of the stockholders or
otherwise except for cause, and then only by the affirmative vote of the holders
of at least a majority of the voting power of all outstanding shares of capital
stock of the Corporation generally entitled to vote in the election of
directors, voting together as a single class. Except as may otherwise be
provided by law, cause of removal of a director shall be deemed to exist only
if: (i) the director whose removal is proposed has been convicted, or where a
director is granted immunity to testify where another has been convicted, of a
felony by a court of competent jurisdiction and such conviction is no longer
subject to direct appeal; (ii) such director has been found by the affirmative
vote of a majority of the entire Board of Directors at any regular or special
meeting of the Board of Directors called for that purpose or by a court of
competent jurisdiction to have been grossly negligent or guilty of misconduct in
the performance of his duties to the Corporation in a matter of 


                                     - 3 -
<PAGE>   88
substantial importance to the Corporation; or (iii) such director has been
adjudicated by a court of competent jurisdiction to be mentally incompetent,
which mental incompetency directly affects his ability as a director of the
Corporation.

        C. Vacancies. Newly created directorships resulting from any increase in
the number of directors and any vacancies on the Board of Directors resulting
from death, resignation, removal or other cause shall be filled by the
affirmative vote of a majority of the remaining directors then in office, even
though less than a quorum of the Board of Directors. Any director elected in
accordance with the preceding sentence shall hold office for the remainder of
the full term of the class of directors in which the new directorship was
created or the vacancy occurred and until such director's successor shall have
been elected and qualified or until his earlier death, resignation or removal.
No decrease in the number of directors constituting the Board of Directors shall
shorten the term of any incumbent director.



                                    ARTICLE X

                                 INDEMNIFICATION

        A. Mandatory Indemnification. Each person who at any time is or was a
director or officer of the Corporation, and is threatened to be or is made a
party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative, arbitrative or investigative (a
"Proceeding"), by reason of the fact that such person is or was a director or
officer of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, partner, venturer, proprietor, member,
employee, trustee, agent or similar functionary of another domestic or foreign
corporation, partnership, joint venture, sole proprietorship, trust, employee
benefit plan or other for-profit or non-profit enterprise, whether the basis of
a Proceeding is an alleged action in such person's official capacity or in
another capacity while holding such office, shall be indemnified and held
harmless by the Corporation to the fullest extent authorized by the DGCL, or any
other applicable law as may from time to time be in effect (but, in the case of
any such amendment or enactment, only to the extent that such amendment or law
permits the Corporation to provide broader indemnification rights than such law
prior to such amendment or enactment permitted the Corporation to provide),
against all expense, liability and loss (including, without limitation, court
costs and attorneys' fees, judgments, fines, excise taxes or penalties, and
amounts paid or to be paid in settlement) actually and reasonably incurred or
suffered by such person in connection with a Proceeding, and such
indemnification shall continue as to a person who has ceased to be a director or
officer of the Corporation or a director, officer, partner, venturer,
proprietor, member, employee, trustee, agent or similar functionary of another
domestic or foreign corporation, partnership, joint venture, sole
proprietorship, trust, employee benefit plan or other for-profit or non - profit
enterprise, and shall inure to the benefit of such person's heirs, executors and
administrators. The Corporation's obligations under this Section A include, but
are not limited to, the convening of any meeting, and the consideration of any
matter thereby, required by statute in order to determine the eligibility of any
person for indemnification.

        B. Prepayment of Expenses. Expenses incurred by a director or officer of
the Corporation in defending a Proceeding shall be paid by the Corporation in
advance of the final disposition of such Proceeding to the fullest extent
permitted by, and only in compliance with, the DGCL or any other applicable laws
as may from time to time be in effect, including, without limitation, any
provision of the DGCL which requires, as a condition precedent to such expense
advancement, the delivery to the Corporation of an undertaking, by or on behalf
of such director or officer, to repay all amounts so advanced if it shall
ultimately be determined that such director or officer is not entitled to be
indemnified under Section A of this Article X or otherwise. Repayments of all
amounts so advanced shall be upon such terms and conditions, if any, as the
Corporation's Board of Directors deems appropriate.


                                     - 4 -
<PAGE>   89
        C. Vesting. The Corporation's obligation to indemnify and to prepay
expenses under Sections A and B of this Article X shall arise, and all rights
granted to the Corporation's directors and officers hereunder shall vest, at the
time of the occurrence of the transaction or event to which a Proceeding
relates, or at the time that the action or conduct to which such Proceeding
relates was first taken or engaged in (or omitted to be taken or engaged in),
regardless of when such Proceeding is first threatened, commenced or completed.
Notwithstanding any other provision of this Certificate of Incorporation or the
Bylaws of the Corporation, no action taken by the Corporation, either by
amendment of this Certificate of Incorporation or the Bylaws of the Corporation
or otherwise, shall diminish or adversely affect any rights to indemnification
or prepayment of expenses granted under Sections A and B of this Article X which
shall have become vested as aforesaid prior to the date that such amendment or
other corporate action is effective or taken, whichever is later.

        D. Enforcement. If a claim under Section A or Section B or both Sections
A and B of this Article X is not paid in full by the Corporation within thirty
(30) days after a written claim has been received by the Corporation, the
claimant may at any time thereafter bring suit in a court of competent
jurisdiction against the Corporation to recover the unpaid amount of the claim
and, if successful in whole or in part, the claimant shall also be entitled to
be paid the expense of prosecuting such claim. It shall be a defense to any such
suit (other than a suit brought to enforce a claim for expenses incurred in
defending any Proceeding in advance of its final disposition where the required
undertaking, if any is required, has been tendered to the Corporation) that the
claimant has not met the standards of conduct which make it permissible under
the DGCL or other applicable law to indemnify the claimant for the amount
claimed, but the burden of proving such defense shall be on the Corporation. The
failure of the Corporation (including its Board of Directors, independent legal
counsel, or stockholders) to have made a determination prior to the commencement
of such suit as to whether indemnification is proper in the circumstances based
upon the applicable standard of conduct set forth in the DGCL or other
applicable law shall neither be a defense to the action nor create a presumption
that the claimant has not met the applicable standard of conduct. The
termination of any Proceeding by judgment, order, settlement, conviction, or
upon a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which such
person reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal Proceeding, had reasonable cause
to believe that his conduct was unlawful.

        E. Nonexclusive. The indemnification provided by this Article X shall
not be deemed exclusive of any other rights to which a person seeking
indemnification may be entitled under any statute, bylaw, other provisions of
this Certificate of Incorporation, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in such person's
official capacity and as to action in another capacity while holding such
office.

        F. Permissive Indemnification. The rights to indemnification and
prepayment of expenses which are conferred to the Corporation's directors and
officers by Sections A and B of this Article X may be conferred upon any
employee or agent of the Corporation if, and to the extent, authorized by the
Board of Directors.


                                     - 5 -
<PAGE>   90
        G. Insurance. The Corporation shall have power to purchase and maintain
insurance, at its expense, on behalf of any person who is or was a director,
officer, employee or agent of the Corporation, or is or was serving at the
request of the Corporation as a director, officer, partner, venturer,
proprietor, member, employee, trustee, agent or similar functionary of another
domestic or foreign corporation, partnership, joint venture, sole
proprietorship, trust, employee benefit plan or other for-profit or non-profit
enterprise against any expense, liability or loss asserted against such person
and incurred by such person in any such capacity, or arising out of such
person's status as such, whether or not the Corporation would have the power to
indemnify such person against such expense, liability or loss under the
provisions of this Article X, the Corporation's Bylaws, the DGCL or other
applicable law.

        H. Implementing Arrangements. Without limiting the power of the
Corporation to procure or maintain insurance or other arrangement on behalf of
any of the persons as described in Section G of this Article X, the Corporation
may, for the benefit of persons eligible for indemnification by the Corporation,
(i) create a trust fund, (ii) establish any form of self-insurance, (iii) secure
its indemnity obligation by grant of a security interest or other lien on the
assets of the Corporation, or (iv) establish a letter of credit, guaranty or
surety arrangement.



                                   ARTICLE XI

                           LIMITED DIRECTOR LIABILITY

        No director of the Corporation shall be personally liable to the
Corporation or to its stockholders for monetary damages for breach of fiduciary
duty as a director, provided that this Article XI shall not eliminate or limit
the liability of a director: (i) for any breach of the director's duty of
loyalty to the Corporation or its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the DGCL, as it may hereafter be amended from
time to time, for any unlawful payment of a dividend or unlawful stock purchase
or redemption, or (iv) for any transaction from which the director derived an
improper personal benefit.

        If the DGCL is amended to authorize corporate action further eliminating
or limiting the personal liability of directors, then the liability of a
director of the Corporation shall be eliminated or limited to the fullest extent
permitted by the DGCL, as so amended. No amendment to or repeal of this Article
XI will apply to, or have any effect on, the liability or alleged liability of
any director of the Corporation for or with respect to any acts or omissions of
the director occurring prior to such amendment or repeal.



                                   ARTICLE XII

                                     BYLAWS

        The Board of Directors is expressly authorized to adopt, amend or repeal
the Bylaws of the Corporation, or adopt new Bylaws, without any action on the
part of the stockholders, except as may be otherwise provided by applicable law
or the Bylaws of the Corporation.



                                  ARTICLE XIII

                           ARRANGEMENTS WITH CREDITORS

        Whenever a compromise or arrangement is proposed between the Corporation
and its creditors or any class of them and/or between the Corporation and its
stockholders or any class of them, any court of 


                                     - 6 -
<PAGE>   91
equitable jurisdiction within the State of Delaware may, on the application in a
summary way of the Corporation or of any creditor or stockholder thereof, or on
the application of any receiver or receivers appointed for the Corporation under
Section 291 of Title 8 of the Delaware Code, order a meeting of the creditors or
class of creditors, and/or of the stockholders or class of stockholders of the
Corporation, as the case may be, to be summoned in such manner as the said court
directs. If the majority in number representing three-fourths in value of the
creditors or class of creditors, and/or of the stockholders or class of
stockholders, of the Corporation, as the case may be, agree to any compromise or
arrangement and to any reorganization of the Corporation as a consequence of
such compromise or arrangement, the said compromise or arrangement and the said
reorganization shall, if sanctioned by the court to which the said application
has been made, be binding on all the creditors or class of creditors, and/or on
all the stockholders or class of stockholders, of the Corporation, as the case
may be, and also on the Corporation.



                                   ARTICLE XIV

                     NOTES TO PRO FORMA FINANCIAL STATEMENTS
                 FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1996
                               (CANADIAN DOLLARS)
                                   (UNAUDITED)

1.       BASIS OF PRESENTATION

         The accompanying unaudited pro forma financial statements of Optima
         Petroleum Corporation ("OPC") have been prepared by management in
         accordance with accounting principles generally accepted in Canada.

         The pro forma statements have been prepared from the audited
         consolidated financial statements of OPC for the years ended December
         31, 1997 and 1996 and from audited financial statements of American
         Explorer, LLC ("AMEX") for the years ended December 31, 1997 and 1996,
         together with other publicly available information. In the opinion of
         management, these pro forma statements include all adjustments
         necessary for fair representation.

         The pro forma statements do not include the financial position and
         results of operations of Goodson Exploration Company, NAB Financial,
         L.L.C. or Dexco Energy, Inc., all of which will be acquired under the
         proposed acquisition, as all assets and liabilities of these companies,
         except for their investments in AMEX, will be removed immediately prior
         to the acquisition.

         The audited financial statements of AMEX have been translated from U.S.
         dollars to Canadian dollars using the current rate method. Under this
         method, the balance sheet at December 31, 1997 is translated at a
         current exchange rate at this date of $1.4305 and the statements of
         operations are translated at the average exchange rate for the year
         presented (1997 - $1.3846; 1996 - $1.3635).

         The pro forma statements are not necessarily indicative of either the
         results of operations that would have occurred for the year ended
         December 31, 1997, or of the results of operations expected in 1998 and
         future years. In preparing these pro forma statements, no adjustments
         have been made to reflect the operating synergies and general and
         administrative cost savings expected to result from consolidating the
         operations of OPC and AMEX.

         These pro forma statements should be read in conjunction with the
         audited consolidated financial statements and notes thereto of OPC and
         the audited financial statements and notes thereto of AMEX for the
         years ended December 31, 1997 and 1996.

2.       PRO FORM ASSUMPTIONS AND ADJUSTMENTS

         The pro forma consolidated balance sheet gives effect to the
         acquisition of AMEX and the share issue as at December 31, 1997. The
         pro forma combined statements of operations for the year ended December
         31, 1997 gives effect to the acquisition and the share issue as of
         January 1, 1997, including adjustments in respect to certain
         transactions that may not occur in future years. The pro forma combined
         statements of operations for the year ended December 31, 1996 gives
         effect to the acquisition and the share issue as of January 1, 1996,
         including adjustments in respect of certain transactions that may not
         occur in future years.

         These pro forma statements give effect to the following assumptions and
         adjustments:

         (a)      Accounting for the acquisition of AMEX is by the purchase
                  method of accounting. The following table shows the
                  assumptions made with respect to the allocation of the
                  aggregate purchase price to AMEX's net assets and the
                  adjustments necessary to their historical cost carrying value.
                  Included as part of the adjustments is the elimination of
                  AMEX's shareholders' equity of $5,769,970.

         We have audited the accompanying balance sheets of American Explorer,

years then ended. 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 audit 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.

                          NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1996

NOTE A -ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

         American Explorer, L.L.C. (the "Company") is a Louisiana limited
liability company headquartered in Lafayette, Louisiana. The Company was formed
in March, 1995, through contributions by its members (two individual S-Corps and
a Louisiana limited liability company; collectively "the Members") of interests
in certain oil and gas properties. These initial contributions were recorded by
the Company during 1995 at each Member's respective cost in such properties. The
Company is engaged in the acquisition of and exploration for oil and natural gas
with operations onshore in South Louisiana and offshore in the Gulf of Mexico.

Use of Estimates

         The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

Oil and Gas Properties

         The Company utilizes the full-cost method of accounting, which involves
capitalizing all acquisition, exploration and development costs incurred for the
purpose of finding oil and gas reserves, including the costs of drilling and
equipping productive wells, dry hole costs, lease acquisition costs and delay
rentals. The Company also capitalizes the portion of general and administrative
costs which can be directly identified with acquisition, exploration or
development of oil and gas properties. Costs associated with unevaluated
properties are excluded from amortization. Unevaluated property costs are
transferred to evaluated property costs at such time as wells are completed on
the properties, the properties are sold, or management determines these costs to
have been impaired. Cost of properties, including future development, site
restoration, dismantlement and abandonment costs, which have proved reserves and
those which have been determined to be worthless, are depleted on the units of
production method based on proved reserves. Additionally, the capitalized costs
of oil and gas properties cannot exceed the present value of the estimated net
cash flow from its proved reserves, together with the lower of cost or estimated
fair value of its undeveloped properties (the full cost ceiling). Transactions
involving sales of reserves in place, unless extraordinarily large portions of
reserves are involved, are recorded as adjustments to accumulated depreciation,
depletion and amortization.

         Upon the acquisition or discovery of oil and gas properties, management
estimates the future net costs to be incurred to dismantle, abandon and restore
the property using geological, engineering and regulatory data available. Such
cost estimates are periodically updated for changes in conditions and
requirements. Such estimated amounts are considered as part of the full cost
pool subject to amortization upon acquisition or discovery. Such costs are
capitalized as oil and gas properties as the actual restoration, dismantlement
and abandonment activities take place.

Other Assets

         The Company has capitalized certain organization costs incurred in
connection with the formation of the Company and costs associated with the bank
note. Organization costs are being amortized over a sixty month period and loan
costs are amortized over the life of the loan.
<PAGE>   107
Cash and Cash Equivalents

         The Company considers all highly liquid investments in overnight
securities made through its commercial bank accounts, which result in available
funds the next business day, to be cash and cash equivalents.

Certain Concentrations

         During 1997 and 1996, 79% and 82% respectively, of the Company's oil
and gas production was sold to three customers. Based on the current demand for
oil and gas, the Company does not believe the loss of any of these customers
would have a significant financially disruptive effect on its business or
financial condition.

Income Taxes

         The Company is not a taxable entity and incurs no liability for federal
or state income taxes. Instead, the Company's taxable income or loss and related
taxable items are allocated to the Members in accordance with the operating
agreement.

Fair Value of Financial Instruments

         The fair value of cash and cash equivalents, accounts receivable and
accounts payable approximates book value at December 31, 1997 and 1996 due to
the short-term nature of these accounts. The fair value of the note payable
approximates book value due to the variable rate of interest charged.

NOTE B - NOTE PAYABLE

         At December 31, 1996 the Company's Note Payable was to a bank with
interest at prime plus 2% (10 1/4%). This note was fully repaid in August, 1997.
The note was collateralized by certain of the Company's and Members' oil and gas
properties and was further secured by personal guarantees of the Members.

         In October 1997, the Company entered into an agreement with a bank for
a reducing revolving line of credit with an initial borrowing base of
$4,000,000. This borrowing base was reduced $220,000 per month through February
1998 when it was redetermined and set at $3,700,000. Beginning April 1, 1998,
the borrowing base is reduced $210,000 per month and is redetermined
semi-annually. The current portion of this note payable of $1,800,000 was
therefore determined to be the sum of the required borrowing base reductions
during 1998. If, upon redetermination, the amount outstanding under the line
exceeds the borrowing base, the Company is required to either pay down the line
of credit to the borrowing base, provide additional collateral to the lender, or
some combination of the two. The Company may borrow, pay and reborrow under the
line of credit until June 1, 2000, on which date, the Company must repay in full
all amounts then outstanding. Outstanding amounts bear interest at prime plus
3/4% (9.25% at December 31, 1997) and are secured by substantially all of the
Company's oil and gas properties. A commitment fee of .50% per annum on the
unused available borrowing base is payable quarterly.

         The line of credit agreement contains various covenants including
restrictions on additional indebtedness and distributions to Members as well as
maintenance of certain financial ratios. The Company is in compliance with these
covenants at December 31, 1997.

NOTE C - RELATED PARTY TRANSACTIONS

         American Explorer, L.L.C. has no employees. It is managed by American
Explorer, Inc. (AEI), a corporation owned by two Members of the Company. In
addition, AEI is the operator of certain of the oil and gas wells in which the
Company has an interest. In 1997 and 1996, AEI charged the Company management
<PAGE>   108
fees of $520,000 and $444,000, respectively. Of these amounts $239,200 and
$155,430 were capitalized as part of the acquisition, exploration and
development effort (See Note A) in 1997 and 1996, respectively. The remainder is
included in general and administrative expense. At December 31, 1997, and 1996
the Company owed AEI approximately $2,458,000, and $1,423,000, respectively.
These amounts are included in Accounts Payable.

         In June, 1997, the Members contributed their interests in the Valentine
Field to the Company. The contribution was recorded at the amount of the
Members' cost in the Valentine Field of approximately $53,000.

NOTE D - ESCROWED FUNDS

         At December 31, 1996, the Company had approximately $1,303,000
remaining in a restricted escrow account set up to secure the Company's plugging
and abandonment liability associated with its ownership interest in an oil and
gas field in Lafourche Parish, Louisiana. In February 1997, the Company received
approval for a Site Specific Trust Account in accordance with the Louisiana
Oilfield Site Restoration Law.

Accordingly, the $1,303,000 in the escrow account became available for general
company purposes. In addition, beginning March 1, 1997, the Company is required
to deposit $10,000 per month into a trust account until the amount reaches
approximately $1,800,000 (the "Approved Amount"). As wells and/or sites are
plugged and cleaned up, the Approved Amount may be adjusted accordingly. At
December 31, 1997, the balance in the Site Specific Trust Account was $100,500.

         During 1996, in connection with its acquisition of an interest in
another oil and gas field in Lafourche Parish, Louisiana, the Company was
required to fund an escrow account up to approximately $235,000 for its share of
the plugging and abandonment of this oil and gas field. The account was fully
funded at December 31, 1996. During 1997, in connection with the Members'
contribution of their interest in this oil and gas field to the Company (See
Note C), the Members' interest in the related plugging and abandonment escrow of
approximately $440,000 was also contributed. At December 31, 1997, this escrow
account is fully funded with a balance of approximately $675,000.

NOTE E - INVESTMENT IN OIL AND GAS PROPERTIES

         The following table discloses certain financial data relative to the
Company's oil and gas producing activities, all of which are located onshore and
offshore in the continental United States.

NOTE F - COMMITMENTS AND CONTINGENCIES

                  As described in Note D, a Site Specific Trust Account and an
Escrow Account have been established for future plugging and abandonment
obligations on certain of the Company's oil and gas properties. The management
of the Company believes that these funds will be sufficient to offset those
future liabilities; however, the Company is responsible for any plugging and
abandonment expense in excess of the balances in these accounts. In addition,
the Company has working interest in other oil and gas properties for which it
will be responsible for its share of the cost of plugging and abandonment of
such properties. At December 31, 1997, the Company's share of total estimated
future plugging and abandonment costs was approximately $2,148,000.

NOTE  G- SUBSEQUENT EVENT

         On February 12, 1998, an agreement was signed to effectively merge
American Explorer, L.L.C. with Optima Petroleum Corporation (Optima). Under the
terms of the Agreement, the Members of the Company will receive shares of Optima
stock in exchange for their interests in the Company. Optima will be redomiciled
as a U.S. (Delaware) Corporation headquartered in Lafayette, Louisiana. All of
the Company's officers will become officers of Optima. The transaction is
subject to approval by Optima shareholders, U.S. and Canadian regulatory
authorities, an independent fairness opinion and certain customary due
diligence.

         As a result of the merger, the Company will become a taxable entity
subject to Federal and State income taxes. The Company will also be required to
establish a net deferred tax liability calculated at the applicable Federal and
State tax rates resulting primarily from financial reporting and income tax
reporting basis differences in oil and gas properties. At December 31, 1997,
such net deferred tax liability would have been approximately $500,000.

NOTE H - OIL & GAS RESERVE INFORMATION - UNAUDITED

         The Company's net proved oil and gas reserves have been estimated by
independent petroleum consultants in accordance with guidelines established by
the Securities and Exchange Commission ("SEC"). Accordingly, the following
reserve estimates are based upon existing economic and operating conditions at
the respective dates.

         There are numerous uncertainties inherent in estimating quantities of
proved reserves and in providing the future rates of production and timing of
development expenditures. The following reserve data represents estimates only
and should not be construed as being exact. In addition, the present values
should not be construed as the current market value of the Company's oil and gas
properties or the cost that would be incurred to obtain equivalent reserves.

         The following table sets forth an analysis of the Company's estimated
quantities of net proved and proved developed oil (including condensate) and
gas, all located onshore and offshore in the continental United States:

                  The following tables present the standardized measure of
future net cash flows related to proved oil and gas reserves together with
changes therein, as defined by the FASB. The oil, condensate and gas price
structure utilized to project future net cash flows reflects current prices at
each year end and has been escalated only where known and determinable price
changes are provided by contracts and law. Future production and development
costs are based on current costs with no escalations. Estimated future cash
flows have been discounted to their present values based on a 10% annual
discount rate.

                  Crude oil and natural gas prices have declined subsequent to
December 31, 1997. Accordingly, the discounted future net cash flows would be
reduced if the standardized measure was calculated at the latter date. As a
result of the continued volatility in oil and natural gas markets, future prices
received from oil, condensate and natural gas sales may be higher or lower than
current levels.

         management, please insert your appointed proxyholder's name in the

         abstained from voting in accordance with the instructions of the
         shareholder on any ballot of a resolution that may be called for and,
         if the shareholder specifies a choice with respect to any matter to be
         acted upon, the securities will be voted accordingly. With respect to
         any amendments or variations in any of the resolutions shown on the
         Proxy, or matters which may properly come before the Meeting, the
         securities will be voted by the nominee appointed as the proxyholder,
         in its sole discretion, sees fit.

6.       If the shareholder votes by completing and returning the Proxy, the
         shareholder may still attend the Meeting and vote in person should the
         shareholder later decide to do so. To vote in person at the Meeting,
         the shareholder must revoke the Proxy in writing as set forth in the

         shareholder or by the shareholder's attorney duly authorized by the
         shareholder in writing, or, in the case of a corporation, by its duly

         executed by an attorney for an individual shareholder or joint
         shareholders or by an officer or an attorney of a corporate
         shareholder, the instrument so empowering the officer or the attorney,
