         According to the Schedule 14D-1, the principal executive office of
Total is located at 24, cours Michelet, La Defense 10, 92800 Puteaux, France.

ITEM 3.  IDENTITY AND BACKGROUND

         (a)  The name and business address of PetroFina, which is the person
filing this Statement, are set forth in Item 1 above.

         (b)     Except as set forth in this Item 3(b) and disclosed in
Exhibits (c)(1), (c)(2) and (c)(3), to the knowledge of PetroFina, there are no
material contracts, agreements, arrangements or understandings and no actual or
potential conflicts of interest between PetroFina or its affiliates and (i)
PetroFina's executive officers, directors or affiliates or (ii) Total or its
respective executive officers, directors or affiliates.

         Effective January 14, 1999, Total acquired approximately 41% of the
outstanding shares of PetroFina from five of PetroFina's largest shareholders,
Electrafina SA, Compagnie Nationale a Portefeuille S.A. (Fibelpar), Tractabel
N.V., Electrabel N.V. and Fortis AG (the "Contributing Shareholders") in
exchange for shares of Total pursuant to a Protcole d' Accord General and a
Convention d'Apports en Nature (collectively, the "Contribution Agreements").

         On December 1, 1998, the Board of Directors of Total (the "Total
Board") and the Contributing Shareholders announced the proposed transaction
and entered into the Contribution Agreements.  The description of the
Contribution Agreements below is qualified in its entirety by reference to the
Contribution Agreements, which are filed as Exhibits (c)(1) and (c)(2) hereto
and are incorporated by reference.  Following the execution of the Contribution
Agreements, Investor, a subsidiary of Compagnie Nationale a Portefeuille,
affiliated to Fibelpar, was substituted as a party to the Contribution
Agreements.  Pursuant to the Contribution Agreements, the Contributing
Shareholders contributed their PetroFina Shares to Total effective as of
January 14, 1999, following approval of the transaction by (i) European and the
U.S. antitrust authorities and (ii) the combined ordinary and extraordinary
shareholders' meeting of Total.  The waiting period under the Hart-Scott Rodino
Antitrust Improvements Act of 1976 expired on January 17, 1999.  The approval
of the European Commission as to competition law matters was received March 26,
1999.  The shareholders' meeting of Total held on January 14, 1999 approved the
proposed transaction and the corresponding capital increase by a 97% majority.
Pursuant to the Contribution Agreements, Total issued 43,263,855 shares of
Total, nominal value 50 French francs per share ("Total Shares") in exchange
for the 9,614,190 PetroFina Shares contributed by the Contributing
Shareholders.  Total has agreed not to sell the PetroFina Shares contributed to
Total under the Contribution Agreements until January 14, 2001.

         The PetroFina Shares contributed to Total entitle Total to dividend
rights as of January l, 1998, except for the dividend paid to shareholders of
PetroFina for the fiscal year ended 1998 in the amount of BEF 460 per each
share of PetroFina.





                                     - 2 -
<PAGE>   4
         The new Total Shares issued as payment for the PetroFina's controlling
shareholders contributions to Total share capital were issued with dividend
rights as at January 1, 1998, i.e., including any dividend declared for the
1998 fiscal year.

         Electrafina has also agreed that, until January 14, 2004, it will not
solely, or together with Groupe Bruxelles Lambert, cause any affiliates of
either of them not to own in the aggregate more than 10% of the outstanding
Total Shares.  A copy of the Memorandum of Understanding between Total and
Electrafina dated December 1, 1998 is filed as Exhibit (c)(3) hereto and is
incorporated by reference.  Should Electrafina and its affiliates in the
aggregate hold more than 10% of the outstanding Total Shares, Electrafina will
have 30 days to sell the Total Shares exceeding this 10% holding.  This
agreement is automatically renewable for additional one year periods if no
notice of termination is given to the other party at least 3 months prior to
end the current period.

         Electrafina has also acknowledged that it holds Total Shares as a
long-term investment. Therefore, Electrafina will discuss with Total any
proposed transfer to Total Shares or other securities which give the holder
rights to Total Shares before making any such transfer.

         Pursuant to the Contribution Agreements, Total was committed to make a
public exchange offer for all of the remaining PetroFina Shares in exchange for
newly issued Total Shares at the exchange ratio of 9 Total Shares for 2
PetroFina Shares.  Upon completion of the Offer, Total has expressed its
intention to combine its operations with those of PetroFina, to maintain
PetroFina's separate legal existence, to change its name to Total Fina and to
apply for stock exchange listing of the Total Shares to be issued pursuant to
the Contribution Agreements and the Offer.

         On March 23, 1999, Henrique Bandeira Vieira resigned as a member of
the PetroFina Board of Directors (the "PetroFina Board") and was replaced, as
of March 31, 1999, by Jean-Paul Vettier, Total President of Refining and
Marketing, who has been designated as Managing Director of PetroFina with
responsibility for the downstream operations.

ITEM 4.  THE SOLICITATION OR RECOMMENDATION.

         (a) Recommendation

         The PetroFina Board has by a unanimous vote approved the Offer and
determined that the terms of the Offer are consistent with, and in furtherance
of, the long-term business strategy of PetroFina and are fair to PetroFina's
shareholders.  The PetroFina Board  recommends that the PetroFina shareholders
accept the Offer and tender their PetroFina Shares, PetroFina ADSs and
PetroFina Warrants pursuant to the Offer.

         (b) Reasons

         The following information was provided to Total by PetroFina for 
inclusion in Total's Offer.





                                     - 3 -
<PAGE>   5
         Based on the press release dated December 1, 1998, the proposed
transaction between Total and PetroFina had been considered by the PetroFina
Board at its meeting of December 8, 1998.  At such meeting, the PetroFina Board
discussed the proposed transaction, analyzed the strategic and operational
aspects, studied the elements guaranteeing a significant Belgian contribution
and considered the financial and stock-exchange-related elements of the
proposed transaction.  After such deliberation, the PetroFina Board unanimously
approved the transaction proposal in principle, but final approval remained
subject to review of the prospectus setting forth the terms of the Offer.  In
addition, pursuant to the Royal Decree of November 8, 1989 on public takeover
bids and changes in the control of corporations ("the Royal Decree"), the
PetroFina Board deferred expressing an opinion on the proposed terms of the
offer.

         Under the Royal Decree, the PetroFina Board is required, once they
have received the draft prospectus, to give their opinion concerning the Offer.
In performing this task, the PetroFina Board is required to act in the interest
of the securities holders as a whole, of the creditors and the workers of
PetroFina.  The PetroFina Board reviewed the draft prospectus concerning the
Belgian exchange offer proposed by Total after it was delivered to them on
March 31, 1999.

         The recommendation of the PetroFina Board is based on its
consideration of the interest of the shareholders as a whole.  In considering
the interest of the shareholders as a whole, the PetroFina Board noted that the
proposed transaction will lead to the creation of an industrial group which
will be ranked fifth in the world when taking into account the Exxon Mobil
merger that was announced on December 1, 1998 and third in Europe among oil
companies.  The PetroFina Board further concluded that the strategy to be
carried out by the new group should allow the achievement of both growth and
productivity gains, including important synergies in the four main industrial
sectors of the new group:

         -  Exploration-Production
         -  Refining-Marketing
         -  Petrochemicals, and
         -  Specialty Chemicals.

         The PetroFina Board also noted that the permanence notably of the big
industrial areas of Antwerp and Feluy will be ensured.

         The PetroFina Board considered the Offer at a meeting on April 7,
1999.  The recommendation of the PetroFina Board is also based in part upon
fairness opinions the PetroFina Board received from J.P. Morgan and Paribas,
each to the effect that, as of the date thereof, the consideration to be
received by the shareholders pursuant to the Offer is fair to such shareholders
from a financial point of view.  The full text of the J.P. Morgan Fairness
Opinion and Paribas Fairness Opinion, which sets forth the factors considered
and the assumptions made, is filed as Exhibits (a)(5) and (a)(6) hereto.





                                     - 4 -
<PAGE>   6
         The PetroFina Board based its review on the understanding that Total
would offer nine (9) Total Shares to be created, with a face value of 50 French
francs, bearing dividends from January 1, 1998 in exchange for 2 PetroFina
Shares with coupon no. 16 attached.  In addition, the PetroFina Board
considered the treatment of participants in various employee benefit programs.

         The two firms, on the basis of the Offer and publicly available
information, presented to the PetroFina Board an analysis the financial terms
and conditions of the Offer on the basis of criteria they believed appropriate
for this type of transaction.  After deliberation, the PetroFina Board
concluded that the terms and conditions of the exchange proposed by Total are
fair and that it is in the interest of the holders of PetroFina securities as a
whole to accept the Offer.

         The members of the PetroFina Board, who hold in the aggregate 11,430
PetroFina Shares and 4,906 PetroFina Warrants, all expressed to the PetroFina
Board their intention to tender these PetroFina Shares into the Offer.  In
addition, a PetroFina Board member representing Electrafina, indicated that it
still holds 1,010 PetroFina Shares (the equivalent of 10,100 PetroFina ADSs)
and that it intends to tender these PetroFina Shares into the Offer.  The
PetroFina Board member representing Sofina indicated to the PetroFina Board
that it holds 318,627 PetroFina Shares and that it intends to tender these
shares pursuant to the Offer.

         Based on various considerations, the PetroFina Board also concluded
that the Offer does not prejudice the interest of PetroFina's creditors or
employees.  It was also noted that the Moody's and Standards & Poor's have
reconfirmed PetroFina's credit rating based on the proposed transaction.  The
PetroFina Board accordingly noted that the Offer does not prejudice the
interest of the creditors.

         The PetroFina Board also considered the Offer in relation to the
interests of the workers and concluded that the Offer will not prejudice the
interests of the workers.

         The foregoing discussion of the information and factors considered and
given weight by the PetroFina Board is not intended to be exhaustive.  In view
of the variety of factors considered in its evaluation, the PetroFina Board did
not find it practicable to and did not quantify or otherwise assign relative
weights to the specific factors considered in reaching its determinations and
recommendation.  In addition, individual members of the PetroFina Board may
have given different weights to different factors.

         Opinion of JP Morgan

         The full text of the written opinion of J.P. Morgan dated April 7,
1999, which sets forth among other things, the assumptions made, procedures
followed, matters considered and limitations on the scope of the review
undertaken by J.P. Morgan in rendering its opinion, is filed as Exhibit (a)(6)
hereto and is incorporated herein by reference with the consent of J.P. Morgan.
This opinion should be read carefully and in its entirety.  J.P. Morgan's
opinion is addressed to the PetroFina Board, is directed only to the fairness
of the consideration offered in the Offer, does not address any other aspect of
the proposed transaction and does not constitute a





                                     - 5 -
<PAGE>   7
recommendation to any PetroFina stockholder as to whether to tender PetroFina
Shares in the Offer.  The summary of the opinion of J.P. Morgan set forth in
this Schedule 14D-9 is qualified in its entirety by reference to the full text
of such opinion.

         In arriving at its opinion, J.P. Morgan has reviewed

                 -        the terms of the exchange offer as presented in the
                          prospectus;

                 -        certain publicly available information concerning the
                          business of Total, PetroFina and certain other
                          companies engaged in businesses comparable to those
                          of Total and PetroFina, and the reported market
                          prices for certain other companies' securities deemed
                          comparable;

                 -        publicly available terms of certain transactions
                          comparable to this transaction;

                 -        current and historical market prices of the
                          securities of Total and PetroFina;

                 -        the audited financial statements of Total and
                          PetroFina for the fiscal year ended December 31, 1998
                          and December 31, 1997;

                 -        certain presentation made by the Company and the
                          Buyer in 1998 and in 1999 to equity analysts
                          regarding the performance of their respective
                          businesses and potential synergies that are expected
                          to be realized if this exchange offer is successful;

                 -        the schedule to the report submitted by the Total
                          Board to the combined extraordinary and ordinary
                          shareholders' meeting of January 14, 1999;

                 -        the Independent Valuation Auditors' Report from
                          Dominique Ledouble and Rene Ricol dated January 4, 
                          1999,

                 -        Minutes of a meeting of PetroFina's General Meeting
                          of Shareholders, hold on January 4, 1999 which
                          authorized the payment of a dividend of BEF 460 per
                          share;

                 -        the documents relating to the contribution by certain
                          shareholders of PetroFina ("the Contributing
                          Shareholders") of their shares to Total, such
                          documents being the "Protocole d'Accord General",
                          dated 1st December, 1998, the "Convention d'Apports
                          en Nature" dated 1st December, 1998 and the

                          1998. These documents, which are thereafter referred
                          to as the "Contribution Document", have been made
                          available to LP Morgan by Total.





                                     - 6 -
<PAGE>   8
         In addition, J.P. Morgan has participated in discussions with certain
members of the management of PetroFina and Total with respect to certain
aspects of the exchange offer, the past and current business operations of
PetroFina and Total, the financial condition and future prospects and
operations of PetroFina and certain other matters it believed necessary or
appropriate to our inquiry.  In J.P. Morgan has reviewed such other financial
studies and analyses and considered such other information as it deemed
appropriate for the purposes of this opinion.

         In performing its analysis, J.P. Morgan has used the valuation
methodologies it deemed necessary or appropriate for the purposes of its
opinion.  Its view is based on consideration of the information PetroFina and
Total provided to it until the date of its opinion, its understanding of the
terms upon which Total intends to consummate this exchange offer, the capital
structure of both PetroFina and Total and an assumption that the exchange offer
would be consummated within the time periods contemplated in this Prospectus.

         In giving its opinion, J.P. Morgan relied upon and assumed, without
independent verification, the accuracy and completeness of all information that
was publicly available or was furnished to it by PetroFina and Total or
otherwise reviewed by it, and J.P.  Morgan did not assume any responsibility or
liability therefor.  In particular J.P. Morgan has assumed, based on assurances
it received from the management of Total, that

         (a) other than the Contribution Documents, there were no documents,
         arrangements or agreements, whether written or verbal, between Total
         and any other party, including the Contributing Shareholders and any
         other party to any of the Contribution Documents, in respect of or in
         connection with the contribution of their shares to Total or the
         exchange offer, and

         (b) the Contribution Documents in the form it reviewed fully and
         fairly set out and represent all arrangements and agreements between
         the parties thereto in respect of the contribution or the exchange
         offer.

         J.P. Morgan has not conducted any evaluation or appraisal of any
assets or liabilities. nor have any such evaluations or appraisals been
provided to J.P. Morgan.  In relying on financial analyses provided to it of
potential synergies that may be realised from the exchange offer, J.P. Morgan
has assumed that such analyses had been reasonably prepared based an
assumptions reflecting the best currently available estimates and judgments by
management as to such potential synergies.  There will necessarily be
differences in the tax treatment to shareholders of PetroFina, of the exchange
offer, based on inter alia the tax residence and the status as legal or natural
person of each shareholder, and J.P. Morgan has therefore not considered, and
does not opine upon, any differences in the benefits of the exchange offer that
may exist between the shareholders of PetroFina due to differences in their
respective tax situation and condition.

         J.P. Morgan's opinion is necessarily based on economic, market and
other conditions as in effect on, and the information made available to it as
of April 7, 1999.  Subsequent





                                     - 7 -

developments may affect its opinion and J.P. Morgan does not have any
obligation to update, revise, or reaffirm its opinion.

         In accordance with customary investment banking practice, J.P. Morgan
employed generally accepted valuation methods in reaching its opinion.  The
following is a summary of the material financial analyses utilized by J.P.
Morgan in connection with providing Its opinion.

         As a pre-amble to its analysis J.P. Morgan observed that the
Contributing Shareholders had agreed to an exchange ratio of 9 Total Shares for
2 PetroFina Shares, which is equivalent to a ratio of 4.5 Total Shares to 1
PetroFina Share.  The exchange offer to the market, made on the same terms,
would result, if accepted in full, in PetroFina shareholders owning a share of
approximately 30.4% of the combined entity Total PetroFina.

The elements of J.P. Morgan's analysis included:

- -        Checking the premium implied by the exchange offer against market
         precedent and compare it with the potential value to be created by the
         implementation of the synergies expected to result from a combination
         of Total and PetroFina (paragraph 1 and 2);

- -        Reviewing the relative trading performance of each company for the
         past three years and their current trading performance relative to
         comparable companies (paragraph 3);

- -        Assessing the sharing of the combined pro forma entity based on
         historical and forecast financial contribution and historical market
         capitalisation contribution of each company (paragraph 4 and 5);

- -        Comparing the proposed exchange ratio to the implied exchange ratio
         resulting from a divisional sum of the parts valuation analysis
         primarily based on trading multiples and a discounted cash flow
         analysis for each company (paragraph 6 and 7); and

- -        Testing the results on a pro forma Total PetroFina combined entity
         earnings per share for the potential accretion/dilution of earnings
         for the next three years (paragraph 8).

         1.  Premium offered and Analysis of Selected Comparable Transactions.
J.P. Morgan reviewed 39 recently announced or closed large capitalization
stock-for-stock transactions. J.P. Morgan then compared the implied premiums
resulting from the smaller company's share of the pro forma combined company
resulting from the transaction as compared with the smaller company's market
capitalization relative to the combined market capitalization of the companies
prior to announcement of the transaction.

         J.P. Morgan's analysis showed that for transactions involving smaller
companies with a relative market capitalization comparable to that of PetroFina
pre-announcement, a premium of 20% to 25% matched market precedent.  The
analysis indicated that, based on the closing share prices on November 30,
1998, the day prior to announcement of the merger, the implied





                                     - 8 -
<PAGE>   10
premium paid to PetroFina shareholders was approximately 26%.  The analysis
also indicated that, based on closing share prices on November 17, 1998, the
day prior to rumors of a possible transaction involving PetroFina, the implied
premium paid for the benefit of PetroFina shareholders was approximately 39%.

         J.P. Morgan also measured the premium offered to PetroFina
shareholders by comparing PetroFina's share price on November 17, 1998 and
November 30, 1998 with the implied value of the Total offer on these two dates.
The premium (taking into account the BEF 460 gross dividend per PetroFina share
announced on the transaction date and paid by PetroFina on the January 13,
1998) was 58.3% over the November 17, 1999 reference price and 39.4% over the
November 30, 1999 reference price.

         2. Annual Pre-Tax Synergies. J.P. Morgan reviewed and analyzed the
future synergies expected to result from a combination of Total and PetroFina,
estimated by management to reach a total of approximately BEF 18 billion by
2003 on a pre-tax basis. J.P. Morgan estimated that the present value of
these, using a DCF analysis, was approximately BEF 213 billion and observed
that the premium over reference price offered to PetroFina shareholders
represented between 63% and 79% of the estimated present value of synergies.
In addition to expressing no opinion as to the potential future trading price
of PetroFina common stock, J.P. Morgan also pointed out that there could be no
assurance that thou synergies would be realised.

         3. Relative Trading analysis. J.P. Morgan performed an analysis
comparing PetroFina's and Total's one year prospective price to cash flow
multiple ("P/CF multiple") over the past three years.  The source of these was
the one year prospective P/CF multiple estimates from J.P. Morgan equity
research.  Such analysis indicated that PetroFina has been consistently trading
at a discount to Total.  In addition, J.P. Morgan also analyzed the current
relative trading performance of Total compared to a sample of comparable
companies which included BP Amoco, Shell, Exxon, Chevron, Texaco, Elf
Aquitaine, Norsk Hydro, ENI, Phillips and Repsol.  J.P. Morgan's analysis
indicated that Total's current valuation was at the average of the trading
range of this peer group.

         4. Historical Contribution Analysis. J.P. Morgan reviewed and analyzed
the relative historical contribution of both Total and PetroFina to the
combined pro forma entity.

         The following table illustrates the historical relative market
capitalization contribution by PetroFina to a combined Total PetroFina entity
and the implied exchange ratio on a per share basis;

         J.P. Morgan observed that the relative contribution by PetroFina to a
combined Total PetroFina entity in the most recent full year of PetroFina would
have been between 14.9% and 36.5% depending on the measure used, or a 1.81:1 to
5.94:1 exchange ratio.  J.P. Morgan compared this range of relative
contribution with the approximately 30.4% continuing ownership stake that
PetroFina's shareholders would have in the combined company following the
merger as a result of the proposed 4.5:1 exchange ratio. Sources for the
historical financial information used in connection with the ratios were
PetroFina and Total's annual reports.

         5. Forecast Contribution Analysis. J.P. Morgan reviewed and analyzed
the then most current earnings and after-tax operating cash flow forecasts for
1999, 2000 and 2001 based on IBES estimates.  J.P. Morgan observed that the
implied relative contribution and exchange ratio was forecast to be between
3.70:1 and 4.31:1 based on future earnings and between 4.65:1 and 4.76:1 based
on future after-tax operating cash flow of a combined Total PetroFina entity.

         6. Divisional sum of the parts valuation analysis: J P. Morgan
performed a divisional sum of the parts analysis of both Total and PetroFina
using a discounted cash flow analysis for the upstream segment (using the same
methodology as the one described in paragraph 7 below) and a comparable trading
multiple methodology for the other business segments (downstream, chemicals,
specialty chemicals and paints).

         J.P. Morgan determined a sample of comparable companies for each
segment described below:

                 Downstream - Cia Espanola de Petroleos SA CEPSA, ERG Spa,
         Hellenic Petroleum SA. OMV AG, Tesoro Petroleum Corp., Tosco Corp.,
         Ultramar Diamond Shamrock Corp., Valero Energy Corp. New

                 Chemicals - BASF AG, Dow Chemical Co., DSM NV, Eastman
         Chemical Co., Lyondell Petrochemical Co., Millennium Chemicals Inc.,
         Solvay SA, Union Carbide Corp. New

                 Specialty chemicals - Ciba Specialty Chemicals Holding Inc,
         Clariant AG, Croda International Plc., Crompton & Knowles Corp.,
         Degussa-Huels AG, HB Fuller Co., Imperial Chemical Industries Plc.,
         Rhodia, SKW Trostberg AG, Yule Catte & Co. Plc.

                 Paints - Akzo Nobel NV, Imperial Chemical Industries Plc.,
         Laporte Plc., Lilly Industries Inc., Mcleod Russel Holdings Plc., PPG
         Industries Inc., RPM Inc., Sherwin Williams Co., Valspar Co.

The resulting relative valuation produced an implied exchange ratio of 3.20 to
3.28 Total Shares per PetroFina Share as opposed to the estimated exchange
ratio of 4.5 Total Shares for 1 PetroFina Share.





                                     - 11 -
<PAGE>   13
         7.  Discounted Cash Flow Analysis: J.P. Morgan performed a Discounted
Cash Flow ("DCF") analysis of both PetroFina and Total.  In the absence of
management projections for both companies, J.P. Morgan relied on the companies'
historical performance as well as its market expertise, own judgement and
conversations with management to derive its own set of financial projections
for both companies.  J.P. Morgan used an 11 year financial model with the same
macro-economic assumptions for both companies, in particular concerning oil
price forecasts, foreign exchange rates and inflation.  Unlevered free cash
flows of the companies were calculated as EBIT less taxes plus depreciation
plus amortization less capital expenditures less increase in not working
investment and discounted using the companies Weighted Average Cost of Capital.
The resulting relative valuation produced an implied exchange ratio of 3.11 to
3.20 Total Shares per PetroFina Share as opposed to the estimated exchange
ratio of 4.5 Total Shares for 1 PetroFina Share.

         8. Pro Forma Merger Analysis. J.P. Morgan analyzed the then-current
pro forma Total PetroFina earnings per share forecasts for 1999, 2000 and 2001
based on IBES estimates.  The analysis showed, assuming BEF 18 billion in
synergies phased in over five years, on an equivalent share basis, that the
exchange offer would be accretive from 1999 to PetroFina's shareholders,
including non-recurring integration-related costs.

         The summary set forth above is not a complete description of the
analyses or data presented by J.P. Morgan.  The preparation of a fairness
opinion is a complex process and is not necessarily susceptible to partial
analysis or summary description.  In arriving at its opinion, J.P. Morgan
considered the results of all of its analyses as a whole and did not attribute
any particular weight to any analysis or factor considered by it.  Furthermore,
J.P. Morgan believes that selecting any portion of its analyses, without
considering all analyses, would create an incomplete view of the process
underlying its opinion.  In addition, J.P. Morgan may have given various
analyses and factors more or less weight than other analyses and factors, and
may have deemed various assumptions more or less probable than other
assumptions, so that the ranges of valuation resulting from any particular
analysis described should not be taken as J.P. Morgan's view of the actual
value of PetroFina or Total.  In performing its analyses, J.P. Morgan made
numerous assumptions with respect to industry performance, general business and
economic conditions and other matters, many of which are beyond the control of
PetroFina and Total.  Any estimates contained in J.P. Morgan's analyses are not
necessarily indicative of future results or actual values, which may be
significantly more or less favorable than those suggested by such estimates.

         As a part of its investment banking business, J.P. Morgan and its
affiliates are continually engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, investments for passive
and control purposes, negotiated underwritings, secondary distributions of
listed and unlisted securities, private placements, and valuations for estate,
corporate and other purposes.  J.P. Morgan was selected to advise PetroFina,
and to deliver a fairness opinion with respect to the merger on the basis of
such experience and its familiarity with PetroFina.





                                     - 12 -
<PAGE>   14
         For services rendered in connection with the merger and the delivery
of its opinion, PetroFina has agreed to pay J.P.  Morgan customary transaction
fees.  In addition, PetroFina has agreed to reimburse J.P. Morgan for its
reasonable expenses incurred in connection with its services, including the
fees and disbursements of counsel, and will indemnify J.P. Morgan against
certain liabilities arising out of J.P. Morgan's engagement, including
liabilities under the federal securities laws.  The SEC has taken the position
that such indemnification under the federal securities laws may not be
enforceable if it is found to be against public policy.

         J.P. Morgan has in the past provided financial advisory services to
PetroFina, and in the past has provided financial advisory and other services
to Total.  In the ordinary course of their businesses, J.P. Morgan and its
affiliates may actively trade the debt and equity securities of PetroFina or
Total for their own account or for the accounts of customers and, accordingly,
they may at any time hold long or short positions in such securities.

         Opinion of Paribas

         The PetroFina Board engaged Paribas to act as its financial advisor in
connection with the offer proposed to the shareholders of PetroFina by Total
following the Contribution Agreements signed on December 1, 1998.  The
Contribution Agreements were ratified by Total at its extraordinary
shareholders meeting held on January 14, 1999.  The proposed exchange ratio is
nine (9) new Total Shares with dividend rights as of January 1, 1998 for two
(2) shares issued by PetroFina (with coupons n degree 16 and following 
attached).

         The PetroFina Board instructed Paribas to evaluate, from a financial
perspective, the fairness of the consideration to be received by the
shareholders of PetroFina in the Offer.

         On April 7, 1999, Paribas delivered its opinion to the PetroFina
Board, to the effect that as of such date and based upon and subject to certain
matters stated therein, the terms of the Offer proposed by Total to PetroFina's
shareholders is fair from a financial perspective.

         THE FULL TEXT OF THE FAIRNESS OPINION OF PARIBAS IS FILED AS EXHIBIT
(a)(5) TO THIS SCHEDULE 14D-9, AND IS INCORPORATED HEREIN BY REFERENCE WITH THE
CONSENT OF PARIBAS.  HOLDERS OF PETROFINA ARE URGED TO, AND SHOULD, READ SUCH
OPINION CAREFULLY AND IN ITS ENTIRETY FOR A DISCUSSION OF THE ASSUMPTIONS MADE,
FACTORS CONSIDERED AND LIMITATIONS UPON THE REVIEW UNDERTAKEN BY PARIBAS IN
RENDERING ITS OPINION.

         No limitations were imposed by the PetroFina Board on the scope of
Paribas investigation of the procedures to be followed by Paribas in rendering
its opinion.  In arriving at its opinion, Paribas did not ascribe a specific
range of values to  PetroFina but made its determination as to the fairness of
the consideration to be received by the holders of PetroFina in the Offer on
the basis of the financial and comparative analyses described below.  Paribas
advisory services and opinion were provided for the information and assistance
of the PetroFina





                                     - 13 -
<PAGE>   15
Board, in connection with its consideration of the Offer.  Paribas was not
requested to opine as to, and its opinion does not address, the PetroFina's
underlying business decision to proceed with or effect the Offer.

         The following discussion makes reference to certain assumptions and
estimates which are not specified.  In the judgement of Paribas, such
assumptions and estimates are reasonable and consistent with general market
expectations.

         In rendering its opinion, Paribas reviewed and analyzed :

                 -       a draft of the Exchange Offer Prospectus dated March
                         31, 1999 and the specific terms of the public
                         exchange offer to PetroFina's shareholders;

                 -       the Exchange Agreement dated December 1, 1998;

                 -       the report of the independent experts in respect of
                         the value of the PetroFina Shares dated January 4,
                         1999;

                 -       certain publicly available information concerning
                         Total and PetroFina that Paribas believed to be
                         relevant to its analysis, including, without
                         limitation, each of the annual reports of both
                         companies for the last six financial years, certain
                         interim reports and  the prospectus in respect of the
                         listing of PetroFina Shares on the New York Stock
                         Exchange in 1997;

                 -       In addition, Paribas has reviewed the share prices and
                         trading activity in the shares of both companies on
                         the relevant stock exchanges since the announcement of
                         the operation, compared stock market information on
                         both companies with information relating to major
                         comparable listed companies, analysed publicly
                         available terms of certain recent transactions in the
                         oil and gas sector which are similar with this
                         transaction and performed other studies and analyses
                         as Paribas considered appropriate.

In connection with this opinion, Paribas did not have access to either the
valuation reports prepared by Total's advisors or to Total's business plan.

        In addition, Paribas :

                 -       had several meetings with PetroFina's management
                         regarding PetroFina's past and current activities, its
                         financial situation, its prospects, the synergies that
                         the merger with Total are expected to create, and
                         certain other matters Paribas believed necessary or
                         appropriate to its enquiry.

                 -       had some meetings with Total's management regarding
                         Total's past and current activities, its financial
                         situation, its prospects, the synergies that the





                                     - 14 -
<PAGE>   16
                         merger are expected to create, and certain other
                         matters Paribas believed necessary or appropriate to
                         its enquiry.

                 -       undertook such other studies, analyses and
                         investigations as Paribas deemed appropriate.

        In rendering its opinion, Paribas assumed and relied upon the accuracy
and completeness of the financial and other information that was used without
assuming any responsibility for independent verification of such information
and further relied upon the assurances of management of Total and PetroFina
that it was not aware of any facts or circumstances that would lead them to
believe that such information, taken as a whole, was inaccurate or misleading
in any material respect.

        However, for purposes of its analysis, Paribas also made certain
assumptions and estimates with respect to the future financial performance of
PetroFina and Total from 1999 through 2006.  Paribas discussed the assumptions
on PetroFina with the management of PetroFina.  No such discussions were held
with the management of Total.

        In rendering its opinion, Paribas did not conduct a physical inspection
of the properties and facilities of PetroFina nor Total and did not make or
obtain any evaluations or appraisals of the assets or liabilities of PetroFina
nor Total.  In addition, Paribas was not authorized to solicit and it did not
solicit, any indications of interest from any third party, with respect to the
purchase of all or a part of PetroFina. Paribas' opinion necessarily is based
upon market, economic and other conditions as they existed on, and could be
evaluated as of, the date of its opinion letter.

        In connection with rendering its opinion, Paribas performed certain
financial, comparative and other analyses as described below.  The preparation
of a fairness opinion involves various determinations as to the most
appropriate and relevant methods of financial and comparative analysis and the
application of those methods to the particular circumstances, and, therefore,
such an opinion is not readily susceptible to summary description.
Furthermore, in arriving at its fairness opinion, Paribas did not attribute any
particular weight to any analysis or factor considered by it, but rather made
qualitative judgments as to the significance and relevance of each analysis and
factor.  Accordingly, Paribas believes that its analyses must be considered as
a whole and that considering any portion of such analyses and of the factors
considered, without considering all analysing and factors, could create a
misleading or incomplete view of the process underlying the opinion.  In its
analyses, Paribas made numerous assumptions with respect to industry
performance, general business and economic conditions and other matters, many
of which are beyond the control of PetroFina and Total.  Any estimation
contained in the analyses are not necessarily indicative or actual values or
predictive of future results or values, which may be significantly more or less
favourable than as set forth therein.  In addition, analyses relating to the
value of businesses do not purport to be appraisals or to reflect the prices at
which businesses actually may be sold.

        In accordance with customary investment banking practice, Paribas
employed generally accepted valuation methods in reaching its opinion.  The
following is a summary of all material financial analysis used by Paribas in
connection with providing its opinion to the PetroFina Board on April 7, 1999.

        As part of its investment banking business, Paribas and its affiliates
are continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, secondary
distributions of listed and unlisted securities, private placements, and
valuations for corporate and other purposes.  Paribas has been requested by
PetroFina to render a fairness opinion with respect to the merger on the basis
of such experience and its familiarity with PetroFina.

        Pursuant to a letter agreement dated December 4, 1998, PetroFina
engaged Paribas as a financial advisor in connection with the merger.  Pursuant
to the terms of the Paribas engagement letter, PetroFina has agreed to pay
Paribas a fee equal to BEF 60,000,000 (or approximately US$ 1.5 million) upon
the consummation of the merger or acquisition of a majority of the common stock
of PetroFina by Total.  In addition, PetroFina has agreed to reimburse Paribas
for its reasonable expenses incurred in connection with its services, and will
indemnify Paribas against certain liabilities arising out of Paribas'
engagement, including liabilities under the federal securities laws.  The SEC
has taken the position that such indemnification under the federal securities
laws may not be enforceable if it is found to be against public policy.


METHODOLOGY

Paribas used two approaches to assess the fairness of the offer:

                 -       Assessment of the exchange ratio using commonly-used
                         criteria: assuming PetroFina shareholders were offered
                         Total Shares under the terms of the offer;

                 -       Analysis of the conversion value offered to the
                         PetroFina minority shareholders  since the
                         announcement of the transaction: assuming that the
                         high liquidity of the share allows the PetroFina
                         shareholder to sell immediately its shares.


ANALYSIS OF THE TERMS OF THE EXCHANGE OFFER

a) Per share criteria:  To assess the exchange ratio Total/PetroFina, Paribas
reviewed certain historical information commonly used in financial analysis.
In order to be consistent in the methodology, Paribas used the consolidated
accounts based on US GAAP principles (Total accounts were reconciliated from
French GAAP to US GAAP).





                                     - 16 -
<PAGE>   18
                 -       historical net earnings per share (EPS) and cash flow
                         per share (CFPS): This approach consists in comparing
                         the proposed exchange ratio with the historical
                         exchange ratio based on recurring EPS and CFPS.

                 -       historical shareholder's equity per share:  This
                         approach consists in comparing the proposed exchange
                         ratio with the historical exchange ratio based on
                         shareholders equity per share.

                 -       Dividend and distribution policy:  This approach
                         consists in comparing the proposed exchange ratio with
                         the historical exchange ratio based on the parity
                         resulting from recent dividend paid by Total and
                         PetroFina.  This criteria highlights potential
                         differences between the historical dividend policy of
                         the two companies.  This analysis is difficult given
                         the tax impact on the dividends depending on the
                         shareholders nature.

b) Stock market analysis:  taking into account the high liquidity of PetroFina
and Total stocks and the high number of analysts following those two companies,
the historical stock trading analysis is a significant reference in the
analysis of the exchange ratio. Paribas calculated the average of the
historical daily exchange ratios of Total common stock to PetroFina common
stock based on the closing prices for the spot, one month, three months, six
months and one year periods ended November 27, 1998.

c) Selected transaction premiums:  Paribas reviewed and compared certain
information relating to the proposed transaction in relation to certain
publicly available information for  stock-for-stock transactions in the oil
sector and public offers either stock-for-stock or cash offer on the Belgium
market. Paribas compared the premium paid in such transactions to the target's
price one day, one month, three months, six months and one year prior the
announcement (using the weighted average share price).

                 -       Stock for stock Offer of BP on Amoco:  announced on
                         August 11, 1998, the exchange ratio was 3.97 BP common
                         shares for each Amoco share

                 -       Stock for stock offer of Exxon on Mobil: announced on
                         December 1, 1998, the exchange ratio was 1.32015 Exxon
                         shares for each Mobil share

        We also took into account the stock for stock offer of BP Amoco on the
US group Atlantic Richfield (Arco) announced on April 1, 1999.

d) Discounted cash flow analysis:  Paribas performed a discounted cash flow
analysis using projections from 1999-2006.  The purpose of this approach was
not to determine an intrinsic value for PetroFina and Total but to appreciate
the exchange ratio.  A sensibility analysis was conducted on our base case.





                                     - 17 -

        A DCF valuation aims to measure the ability of a company to create
value.  This method relies on future free cash flows from operations.  Value
creation results from the difference between the expected return on capital
employed and the weighted average cost of capital.

        For the oil industry, a DCF valuation is made difficult by the high
volatility of the main operating parameters.  However, we used this method in
order to determine a range of value for PetroFina and Total, based on a wide
number of assumptions regarding the future performance of both companies.

        Financial forecasts are determined for three periods:

                 -       An explicit period, from 1999 to 2006, based on the
                         business plan of the company;

                 -       An intermediary period, from 2007 to 2016, based on a
                         normative cash flow growing at a given rate over the
                         period;

                 -       An implicit period, from 2017 to perpetuity, based on
                         a normative cash flow growing at a given rate.

        The sum of these discounted cash flows represents the value of the
        company's operations. The implied value of the equity is derived by
        subtracting the market value of net debt and minority interests from
        the value of the company's assets, and by adjusting for non- operating
        items.

e) Discarded Methods

Dividend Discount Analysis

Theoretically, the dividend discount analysis should yield the same results as
the Discounted cash flow analysis.  To obtain a relevant value, the dividend
discount analysis requires assumptions on the future dividend policy of both
groups.  In the absence of such assumptions, we discarded this method.

Replacement Cost Analysis (RCA)

We also discarded this method based on the assessment of the assets and
liabilities stated in the financial statements of PetroFina and Total.  Indeed,
there were not enough information to fairly value the intangibles assets of the
group (goodwill, patent, know how...).

Comparable Transaction Multiples

We discarded this method as there was no comparable transaction in Europe.





                                     - 18 -
<PAGE>   20
As PetroFina, Amoco and Mobil are two integrated petroleum groups.  However,
Amoco and Mobil are American companies, and as such have significantly
different trading multiples, from those of European companies, mostly due to
the following factors:

                 -       The US majors operate world-wide and therefore are
                         less subjected to regional issues;

                 -       US cycles are different from European ones,
                         particularly in the refining activity.

These significant differences lead to an irrelevant comparison between the
multiples implied by the terms of the Offer and the multiples implied by the
two selected transactions which took place in the US market.

ANALYSIS OF THE CONVERSION VALUE OFFERED SINCE THE ANNOUNCEMENT OF THE
TRANSACTION

        The analysis of the conversion value offered is conducted applying
various dates to the terms of the exchange.  We have selected two dates to be
our benchmark and analysed the results of changes in the market value.  The
first date is the day prior to the announcement date of the transaction and the
second date is the day before the day we delivered our conclusions to the
PetroFina Board.

        We have analyzed the evolution of the Conversion value offered to a
PetroFina shareholder through the evolution of Total's share prices.

        Additionally, we used the trading multiple analysis, a commonly used
method in the valuation process of a company, to do the analysis of the
conversion value.  The multiples have been computed using the share prices of
Total at the two selected dates, and compared to a sample of comparable
petroleum companies.

1.      EXCHANGE RATIO ANALYSIS

        Paribas calculated historical exchange ratios of Total to PetroFina,
using certain historical commonly used per share ratios (cash flows, ...),
common stock prices of Total and PetroFina on certain periods, comparisons with
selected transactions and valuations of Total and PetroFina's stocks performed
through discounted cash flow analysis.

1.1     PER SHARE TOTAL TO PETROFINA CASH FLOWS, EARNINGS, SHAREHOLDERS FUNDS
AND DIVIDENDS RATIOS: Paribas calculated the 1995 to 1998 above mentioned per
share ratios of Total common stock to PetroFina common stock. Such analysis
indicated:

                 -       that the Total to PetroFina per share cash flows
                         ratios from 1995 to 1998 respectively amounted to 5.6,
                         4.9, 5.0, 5.6, compared to the public exchange ratio
                         of 4.5;





                                     - 19 -
<PAGE>   21
                 -       that the Total to PetroFina recurrent earnings per
                         share ratios from 1995 to 1998 respectively amounted
                         to 5.4, 4.3, 4.5, 5.2, compared to the exchange ratio
                         of 4.5 ;

                 -       that the Total to PetroFina per share shareholder's
                         equity ratios from 1995 to 1998 respectively amounted
                         to 4.0, 3.8, 4.0, 4.3, compared to public the exchange
                         ratio of 4.5;

                 -       that the Total to PetroFina after tax dividend1/
                         ratios from 1995 to 1997 respectively amounted to 5.3,
                         4.9, 4.5, compared to the public exchange ratio of
                         4.5;

                 -       this ratio analysis emphasises the quality of
                         PetroFina's financials. Nevertheless, capital markets
                         have traded PetroFina at a discount to its peers and
                         notably to Total.

1.2     HISTORICAL STOCK TRADING ANALYSIS.  Paribas reviewed the historical
trading prices and volumes for the Total and PetroFina shares both separately
and in comparison to the European Oil integrated (Datastream Europe-DS oil
integrated) price index and to the London Brent Crude Oil price Index (U$/BBL)
for the periods starting respectively in 1973 and in 1990, and ending 27/11/98
(the date before the transaction was publicly announced).  The Historical Stock
trading Analysis showed that (i) Total's share price has been - on a comparable
basis - multiplied by 14 during the 01/01/1973 to 27/11/98 period, whereas
PetroFina's share had only by multiplied by 4 over the same period (ii)
starting in 1990, PetroFina's share constantly under-performed the European Oil
integrated index, that was over-performed by Total over the same period (iii)
based on the 1997 historical earnings figures, Total and PetroFina' P/E ratios
over a period starting on 01/02/1998, show that PetroFina traded at a 12%
discount to its peers, whereas Total traded with an average premium of 37% to
its peers2/ (iv) IBES analysts consensus showed that 56% of those analysts had
a "Hold" position on PetroFina, 24% a "buy" position and 20% a "sell" position,
considering the stock was valued accordingly to their expectations, whereas 79%
of them had a "Buy" recommendation on Total, therefore implying that the stock
was then under-valued.  Paribas calculated the average of the historical daily
exchange ratios of PetroFina common stock to Total common stock for 12 months,
6 months, 3 months, 1 month ended November 27, 1998. Such analysis indicated:

                 -       That the average ratios over such periods were 3.3,
                         3.2, 3.1, 3.1 as compared to the public exchange ratio
                         of 4.5;

                 -       An exchange ratio of 3.3 for the closing price of
                         PetroFina common stock on November 27, 1998, as
                         compared to the public exchange ratio of 4.5.

1.3     ANALYSIS OF SELECTED TRANSACTIONS. Paribas analysed certain information
relating to the Offer in relation to certain publicly available information on
recent public exchange offer transactions on the Brussels's Stock Exchange and
in the Oil sector.

Such analysis indicated that for the selected transactions on the Brussels's
Stock Exchange the premiums paid in such transactions as compared to:

                 -       the target's price (calculated through the exchange
                         ratio proposed) one day prior to the announcement of
                         the transaction (the Announcement Date) ranged from a
                         low of (4.7%) to a high of 18.6%, with a median of
                         2.8% and an average of 4.8%, as compared to 39.2% for
                         the proposed offer;

                 -       the target's 30-day average price (calculated through
                         the exchange ratio proposed) prior to the Announcement
                         Date ranged from a low of 0.7% to a high of 35.6%,
                         with a median of 10.2% and an average of 10.4%, as
                         compared with 51.4% for the proposed offer;

                 -       the target's 3-months average price (calculated
                         through the exchange ratio proposed) prior to the
                         Announcement Date ranged from a low of 3.6% to a high
                         of 41.8%, with a median of 17.9% and an average of
                         18.6%, as compared with 55.1% for the proposed offer;

                 -       the target's 6-months average price (calculated
                         through the exchange ratio proposed) prior to the
                         Announcement Date ranged from a low of 2.1% to a high
                         of 57.4%, with a median of 31.6% and an average of
                         29.7%, as compared with 44.9% for the proposed offer;

                 -       the target's 12-months average price (calculated
                         through the exchange ratio proposed) prior to the
                         Announcement Date ranged from a low of 11.4% to a high
                         of 101.8%, with a median of 45.1% and an average of
                         43.4%, as compared with 44.3% for the proposed offer.

This analysis further indicates that the premium paid in this exchange offer is
significantly higher than the ones shown in the selected transactions, on the
basis of 1-day to 6-months average prices.  On the basis of 12-months average
prices, the premium paid in the proposed exchange offer is consistent with the
ones calculated on our sample of Belgian public offers.

        Such analysis indicated that for the selected transactions in the Oil
sector (Exxon Mobil and BP Amoco) the premiums paid in such transactions as
compared to:

                 -       the target's price (calculated through the exchange
                         ratio proposed) one day prior to the announcement of
                         the transaction (the Announcement Date)





                                     - 21 -
<PAGE>   23
                         ranged from a low of 22.4% to a high of 26.4%, as
                         compared to 39.2% for the proposed offer;

                 -       the target's 30-day average price (calculated through
                         the exchange ratio proposed) prior to the Announcement
                         Date ranged from a low of 23.1% to a high of 33.1%, as
                         compared with 51.4% for the proposed offer;

                 -       the target's 6-months average price (calculated
                         through the exchange ratio proposed) prior to the
                         Announcement Date ranged from a low of 18.4% to a high
                         of 30.5%, as compared with 44.9% for the proposed
                         offer;

                 -       the target's 12-months average price (calculated
                         through the exchange ratio proposed) prior to the
                         Announcement Date ranged from a low of 15.0% to a high
                         of 33.8%, as compared with 44.3% for the proposed
                         offer.

This analysis further indicates that the premium paid in this exchange offer is
significantly higher than the ones paid in other comparable transactions in the
Oil sector.

1.4     DISCOUNTED CASH FLOW ANALYSIS.  Paribas performed a discounted cash
flow analysis for both Total and PetroFina using its own assumptions for both
PetroFina and Total (the assumptions used to value PetroFina have been made by
Paribas on the basis of its own estimates, and on discussions with PetroFina's
management).  Unlevered free cash flows were calculated as EBIT less taxes plus
depreciation less capital expenditures less changes in working capital.  This
analysis has been used to assess the exchange ratio proposed in the offer and
not to perform an intrinsic valuation of both companies.

        Paribas calculated a net present value for the cash flows of both
companies' cash flows for the years 1999 to 2006, an intermediary period from
2007 to 2016 and to terminal values. Paribas calculated terminal values by
applying the Gordon-Shapiro formula, using a perpetual growth rate of 2.5% for
both companies.  The unlevered free cash flow streams and terminal values were
then discounted to the present using a WACC (weighted average cost of capital)
of 7.25% for both companies.  The discounted values were then adjusted by
adding cash and subtracting debt to arrive at implied equity values.  Based on
our analyses, Paribas calculated an exchange ratio, resulting in a PetroFina
to Total per share equity value ratio of 4.4, as compared to the exchange ratio
of 4.5 pursuant to the exchange offer.

        Paribas then conducted a sensitivity analysis based on certain
parameters:  (i) 1% change in 2007-2016 growth rate of free cash flows (ii)
0.5% change in perpetual growth rate beyond 2017 (iii) 0.5% change in WACC
assumption (iv) 1 U$ change in the brent price (U$ price per barrel) (v) 5%
change in the U$/Euro exchange rate.  Based on those analysis, the PetroFina to
Total per share equity value ratio varied in a range comprised between 4.1 to
4.7, as compared to the public exchange ratio of 4.5.

2.1      ANALYSIS OF THE CONVERSION VALUE.  Paribas has reviewed the evolution
of share prices and trading activity in the shares of both companies on the
relevant stock exchanges since the announcement of the operation, and compared
stock market information on both companies with information relating to major
comparable listed companies.

        The analysis of the conversion value consists in analysing the terms of
the exchange  in value for a PetroFina shareholder at certain precise dates.
We used two references for the conversion value, one based on Total share price
on November 27, 1998 just before the announcement of the transaction, and one
based on Total share price on April 1st, 1999 the last trading day before
submitting our conclusion to the PetroFina Board.  The conversion value is
composed of the exchange ratio 4.5 Total share per PetroFina Share plus an
exceptional net dividend of BEF 345 per share (gross dividend of BEF 460 less
equalization tax for BEF 115).

        Using the above formula the conversion value was BEF 19 832 per
PetroFina Share as of November 27, 1998 and BEF 20 531 per PetroFina Share as
of April 1st 1999 (closest available trading data prior to the presentation to
the PetroFina Board).  These conversion values compare to PetroFina share price
of BEF 14 250 as of November 27, 1998 and of BEF 13 739 corresponding to the
average of the twelve months period ending on that day.

2.2      TRADING MULTIPLES ANALYSIS.  Paribas compared the public stock market
trading multiples of Total and PetroFina with those of selected European oil
integrated companies including BP Amoco, Royal Dutch, ENI, Elf, Repsol and
Norsk Hydro.  Using publicly available information, Paribas calculated and
analyzed the market capitalization multiples and equity value multiples of
certain historical and projected financial and operating criteria such as
Earnings, cash flow from operations, EBIT and  EBITDA.

        -        As of November 27, 1998 share prices, the appropriate market
                 capitalization multiples to 1997, 1998, projected 1999
                 Earnings, Operating cash flows were determined to be as
                 follows:

        For the comparable companies, the average projected 1999 P/E and cash
flow multiples were respectively 25.6x and 6.9x.  The average projected 1999
P/E and cash flow multiples of Total Fina showed a 1.1% discount and a 41.0%
premium on those multiples, thus implying a 52.2% premium and a 64.2% premium
compared to PetroFina's multiples as of November 27, 1998.

        We conclude from this trading multiples analysis, that through the
terms of the exchange offer, a PetroFina shareholder accepting to become a
shareholder in Total Fina benefits from a positive re-rating of the value of
his stock.


ITEM 5.

        PetroFina engaged JP Morgan and Paribas to act as it financial advisors
in connection with the Offer.  As part of its role as principal financial
advisor, each of JP Morgan and Paribas delivered to the PetroFina Board a
fairness opinion.  J.P. Morgan's opinion is addressed to the PetroFina Board,
is directed only to the fairness of the consideration offered in the Offer,
does not address any other aspect of the proposed transaction and does not
constitute a recommendation to any PetroFina shareholder as to whether to
tender shares in the Offer.   Paribas advisory services and opinion were
provided for the information and assistance of the PetroFina Board, in
connection with its consideration of the Offer.  Paribas was not requested to
opine as to, and its opinion does not address, PetroFina's underlying
business decision to proceed with or effect the Offer.

        Except as set forth above, neither PetroFina nor any person acting on
its behalf has or currently intends to employ, retain or compensate any person
to make solicitations or recommendations to the PetroFina shareholders on its
behalf with respect to the Offer.

ITEM 6.





                                     - 24 -
<PAGE>   26
        (a)  Except as set forth in Item 3(b), to the best of PetroFina's
knowledge, no transaction in PetroFina Warrants and PetroFina ADSs has been
effected during the past 60 days by the Company or by any executive officer,
director, affiliate or subsidiary of the Company.  However, because PetroFina
Shares may be held in bearer form, PetroFina is unable to confirm whether or
not sales of PetroFina Shares have actually occurred.

        (b)  To PetroFina's knowledge, all of its executive officers, directors
and affiliates or subsidiaries currently intend to tender all PetroFina Shares
which are held of record or beneficially owned by such persons pursuant to the
Offer.

ITEM 7.  CERTAIN NEGOTIATIONS AND TRANSACTIONS BY THE SUBJECT COMPANY

        (a)  Except as set forth herein, PetroFina is not engaged in any
negotiation in response to the Offer which relate to or would result in (i) an
extraordinary transaction, such as a merger or reorganization, involving
PetroFina or any of its subsidiaries; (ii) a purchase, sale or transfer of a
material amount of assets by PetroFina or any of its subsidiaries; (iii) a
tender offer for or other acquisition of securities by or of PetroFina; or (iv)
any material change in the present capitalization or dividend policy of

        Total has indicated in its Schedule 14D-1 that it plans to work with
PetroFina's management to combine the operation of the refining and
distribution businesses in order to leverage the strengths of both entities in
Europe.  In order to reflect the combination of Total and PetroFina, Total has
proposed that at the next meeting of Total shareholders on May 11, 1999, the
shareholders approve the change of Total's corporate name to "Total Fina S.A,"
which would be effective as of June 14, 1999.  In addition, Total has indicated
that following a thorough review of the subsidiaries of Total Fina, some
restructuring may occur.  Total also stated in its Schedule 14D-1 that it did
not intend to modify the dividend policy of PetroFina, but actual payments will
be subject to Total's financial strategy.

        (b)  Except as described in Item 3(b) and Item 4 above (the provisions
of which are hereby incorporated by reference), there are no transactions,
board resolutions, agreements in principle or signed contracts in response to
the Offer which relate to or would result in one or more of the matters
referred to in Item 7(a).

     NONRESIDENT ALIEN INDIVIDUAL: For United States federal income tax
purposes, "nonresident alien individual" means an individual who is neither a
United States citizen nor resident. Generally, an alien is considered to be a
United States resident if:
 
          The individual was a lawful permanent resident of the United States at
     any time during the calendar year, that is the alien held an immigrant visa
     (a "green card"), or
 
          The individual was physically present in the United States on:
 
             (1) at least 31 days during the calendar year, and
 
             (2) 183 days or more during the current year and the two preceding
        calendar years (counting all the days of physical presence in the
        current year, one-third the number of days of presence in the first
        preceding year, and one-sixth of the number of days in the second
        preceding year).
 
     EXEMPT FOREIGN PERSON: If you do not meet the requirements of certification
number two or three above, you may instead certify on Internal Revenue Service
Form 1001, Ownership, Exemption, or Reduced Rate Certificate, that your country
has a tax treaty with the United States that exempts your transactions from
United States tax.

Ladies and Gentlemen:
 
     The undersigned acknowledges that such person has received and reviewed the
Prospectus, dated May 6, 1999 (the "Prospectus"), of Total, a societe anonyme
organized under the laws of the Republic of France ("Total"), and this Letter of
Transmittal, which together with any amendments or supplements hereto or thereto
constitute the offer of Total (collectively, the "Exchange Offer") to exchange
PetroFina securities for Total securities. Unless otherwise defined in this
Letter of Transmittal, capitalized terms used herein have the meaning set forth
in the Prospectus.
 
     The undersigned hereby instructs the US Exchange Agent to accept the
exchange offer on behalf of the undersigned with respect to the PetroFina ADSs
evidenced by PetroFina ADRs (which expression in this Letter of Transmittal
shall, except where the context otherwise requires, be deemed to include,
without limitation, the PetroFina shares represented thereby) specified in the
box entitled "Description of PetroFina ADSs Tendered," subject to the terms and
conditions of the exchange offer, by informing Total in writing that the
exchange offer has been so accepted. The undersigned hereby acknowledges that
delivery of this Letter of Transmittal, the PetroFina ADRs evidencing tendered
PetroFina ADSs (or book-entry transfer of such PetroFina ADSs evidenced by
PetroFina ADRs) and any other required documents to the US Exchange Agent by a
holder of PetroFina ADSs will be deemed (without any further action by the US
Exchange Agent) to constitute acceptance of the exchange offer by such holder in
respect of such holder's PetroFina ADSs, subject to the terms and conditions of
the exchange offer.
 
     The undersigned understands that acceptance of the exchange offer by the
undersigned pursuant to the procedures described herein and in the instructions
hereto, subject to the withdrawal rights described in the Prospectus, will
constitute a binding agreement between the undersigned and Total upon the terms
and subject to the conditions of the exchange offer. IF ACCEPTANCE HAS BEEN MADE
IN RESPECT OF THE PETROFINA ADSs, THEN A SEPARATE ACCEPTANCE IN RESPECT OF THE
PETROFINA SHARES REPRESENTED BY SUCH PETROFINA ADSs MAY NOT BE MADE.
 
     The undersigned hereby delivers to the US Exchange Agent the
above-described PetroFina ADSs evidenced by PetroFina ADRs for which the
exchange offer is being accepted, in accordance with the terms and conditions of
the exchange offer, receipt of which is hereby acknowledged.
 
     Upon the terms of the exchange offer (including, if the exchange offer is
revised, varied, extended or renewed, the terms or conditions of any such
revision, variation, extension, or renewal), and effective at the time that the
condition to the exchange offer has been satisfied, fulfilled or, where
permitted, waived (at which time Total will give notice thereof to the US
Exchange Agent), and if he or she has not validly withdrawn his or her
acceptance, the undersigned hereby sells, assigns and transfers to, or upon the
order of, Total all right, title and interest in and to all PetroFina ADSs
evidenced by PetroFina ADRs with respect to which the exchange offer is being
accepted (and any and all PetroFina ADSs or other securities or rights issuable
in respect of such PetroFina ADSs) and irrevocably constitutes and appoints the
US Exchange Agent the true and lawful agent and attorney-in-fact of the
undersigned with respect to such PetroFina ADSs (and any such other PetroFina
ADSs, securities or rights), with full power of substitution (such power of
attorney being deemed to be an irrevocable power coupled with an interest), to
(a) deliver PetroFina ADSs for such PetroFina ADSs (and any such other PetroFina
ADSs, securities or rights), or accept transfer of ownership of such PetroFina
ADSs (and any such other PetroFina ADSs, securities or rights) on the account
books maintained by The Depository Trust Company together, in any such case,
with all accompanying evidences of transfer and authenticity, to, or upon the
order of, Total, and (b) receive all benefits and otherwise exercise all rights
of beneficial ownership of such PetroFina ADSs (and any such other PetroFina
ADSs, securities or rights), all in accordance with the terms of the exchange
offer.
 
     The undersigned hereby represents and warrants that the undersigned has
full power of authority to accept the exchange offer and to tender, exchange,
sell, assign and transfer the PetroFina ADSs evidenced by PetroFina ADRs (and
the PetroFina shares represented by such PetroFina ADSs) in respect of which the
exchange offer is being accepted or deemed to be accepted (and any and all other
PetroFina ADSs, securities or rights issued or issuable in respect of such
PetroFina ADSs) and Total will acquire good title thereto, free from all liens,
equities, charges, encumbrances and other interests and together with all rights
now or hereafter
                                        4

attaching thereto, including, without limitation, the right to receive and
retain all dividends, interest and other distributions hereafter declared, with
respect to the PetroFina Shares represented by the PetroFina ADSs. The
undersigned will, upon request, execute any additional documents deemed by the
US Exchange Agent or Total to be necessary or desirable to complete the sale,
assignment and transfer of the PetroFina ADSs evidenced by PetroFina ADRs in
respect of which the exchange offer is being accepted (and any and all other
PetroFina ADSs, securities or rights).
 
     The undersigned irrevocably undertakes, represents, and warrants to and
agrees with Total (so as to bind him or her, his or her personal
representatives, heirs, successors and assigns) to the effect that the
undersigned: (i) has not received or sent copies of the Prospectus or any
related documents in, into or from Canada, or any jurisdiction into which the
sending of such documents is prohibited by applicable law, and has not otherwise
utilized in connection with the exchange offer, directly or indirectly, the
Canadian, or the mails or any means or instrumentality (including, without

Canada, or any jurisdiction into which the sending of such documents is
prohibited by applicable law, (ii) is accepting the exchange offer from outside
Canada, or any jurisdiction into which the sending of such documents is
prohibited by applicable law, and (iii) is not an agent or fiduciary acting on a
nondiscretionary basis for a principal, unless such agent or fiduciary is an
authorized employee of such principal or such principal has given any
instructions with respect to the exchange offer from outside Canada, or any
jurisdiction into which the sending of such documents is prohibited by
applicable law.
 
     All authority herein conferred or agreed to be conferred pursuant to this
Letter of Transmittal shall be binding upon the successors, assigns, heirs,
executors, administrators and legal representatives of the undersigned and shall
not be affected by, and shall survive, the death or incapacity of the
undersigned. Except as stated in the Prospectus, this acceptance is irrevocable.
 
     Unless otherwise instructed under "Special Issuance Instructions" below,
the undersigned hereby instructs the US Exchange Agent to register the Total
ADSs to which the undersigned is entitled in the name(s) of the holder(s) shown
above under "Description of PetroFina ADSs Tendered." Unless otherwise
instructed under "Special Delivery Instructions" below, the undersigned hereby
instructs the US Exchange Agent to return, or cause to be returned, any
PetroFina ADRs evidencing PetroFina ADSs in respect of which the exchange offer
is not being accepted or which are not exchanged (and accompanying documents, as
appropriate) and/or deliver the certificates representing the Total ADSs to be
delivered to the undersigned pursuant to the exchange offer to the address(es)
of the registered holder(s) appearing above under "Description of PetroFina ADSs
Tendered." In the case of a book-entry delivery of PetroFina ADSs evidenced by
PetroFina ADRs, the undersigned hereby instructs the US Exchange Agent to credit
the account maintained at The Depository Trust Company with any PetroFina ADSs
in respect of which the exchange offer is not being accepted or which are not
purchased. The undersigned recognizes that the US Exchange Agent will not
transfer any PetroFina ADSs which are not purchased pursuant to the exchange
offer from the name of the registered holder thereof to any other person.
 
     SUBJECT TO THE TERMS OF THE PROSPECTUS, THIS LETTER OF TRANSMITTAL SHALL
NOT BE CONSIDERED COMPLETE AND VALID, AND DELIVERY OF TOTAL ADSs PURSUANT TO THE
EXCHANGE OFFER SHALL NOT BE MADE, UNTIL THE PETROFINA ADRs EVIDENCING THE

OTHER REQUIRED DOCUMENTATION HAVE BEEN RECEIVED BY THE US EXCHANGE AGENT AND THE
UNDERLYING SHARES HAVE BEEN RECEIVED BY THE CUSTODIAN AS PROVIDED IN THE

     3. INADEQUATE SPACE. If the space provided herein is inadequate, the series
numbers of the certificates and/or the number of PetroFina ADSs should be listed
on a separate schedule attached hereto.
 
     4. PARTIAL ACCEPTANCES (NOT APPLICABLE TO BOOK-ENTRY TRANSFERS). If the
exchange offer is to be accepted in respect of less than all of the PetroFina
ADSs evidenced by any PetroFina ADRs delivered to the US Exchange Agent
herewith, fill in the number of PetroFina ADSs in respect of which the exchange
offer is being accepted in the box entitled "Number of PetroFina ADSs Tendered."
In such case, a new PetroFina ADR for the remainder of the PetroFina ADSs (in
respect of which the exchange offer is not being accepted) represented by the
old PetroFina ADR will be sent to the registered holders as promptly as
practicable following the date on which the PetroFina ADSs in respect of which
the exchange offer has been accepted are purchased.
 
     The exchange offer will be deemed to have been accepted in respect of all
PetroFina ADSs evidenced by PetroFina ADRs delivered to the US Exchange Agent
unless otherwise indicated. In the case of partial acceptances, PetroFina ADSs
in respect of which the exchange offer was not accepted will not be reissued to
a person other than the registered holder.
 
     5. SIGNATURES ON LETTER OF TRANSMITTAL, STOCK POWERS AND ENDORSEMENTS. If
this Letter of Transmittal is signed by the registered holder(s) of the
PetroFina ADSs in respect of which the exchange offer is being accepted hereby,
the signature(s) must correspond with the name(s) as written on the face of the
certificates without any change whatsoever.
 
     If any of the PetroFina ADSs evidenced by PetroFina ADRs in respect of
which the exchange offer is being accepted hereby are owned of record by two or
more owners, all such owners must sign this Letter of Transmittal.
 
     If any of the PetroFina ADSs in respect of which the exchange offer is
being accepted are registered in different names on different PetroFina ADRs, it
will be necessary to complete, sign and submit as many separate Letters of
Transmittal as there are different registrations of PetroFina ADRs.
 
     If this Letter of Transmittal or any PetroFina ADRs or stock powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and proper evidence
satisfactory to Total of their authority so to act must be submitted.
 
     When this Letter of Transmittal is signed by the registered holder(s) of
the PetroFina ADSs listed and transmitted hereby, no endorsements of
certificates or separate stock powers are required. Signatures on such PetroFina
ADRs or stock powers must be guaranteed by an Eligible Institution.
 
     If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the PetroFina ADSs listed, the PetroFina ADRs must be
endorsed or accompanied by appropriate stock powers signed exactly as the
name(s) of the registered holder(s) appear(s) on the PetroFina ADRs evidencing
such PetroFina ADSs. Signatures on such PetroFina ADRs or stock powers must be
guaranteed by an Eligible Institution.
 
     6. STOCK TRANSFER TAXES. Total will pay or cause to be paid any stock
transfer taxes with respect to the transfer and sale to it or its order of
PetroFina ADSs evidenced by PetroFina ADRs pursuant to the exchange offer. If,
however, delivery of any of the consideration payable pursuant to the exchange
offer is to be made to any persons other than the registered holder(s), or if
PetroFina ADSs in respect of which the exchange offer is being accepted are
registered in the name of any person other than the person(s) signing this
Letter of Transmittal, the amount of any stock transfer taxes (whether imposed
on the registered holders(s) or such person(s)) payable on account of the
transfer to such person will be deducted from the purchase price (or new Total
Stock will be withheld) unless satisfactory evidence of the payment of such
taxes or exemption therefrom is submitted.
 
     Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the PetroFina ADRs listed in this Letter of
Transmittal.

     7. SPECIAL DELIVERY INSTRUCTIONS. If any PetroFina ADRs evidencing
PetroFina ADSs in respect of which the exchange offer is not being accepted or
which are not purchased are to be returned to a person other than the signer of
this Letter of Transmittal or to an address other than that shown in the box
entitled "Description of PetroFina ADSs Tendered" on the first page of this
Letter of Transmittal, or the new Total Stock is to be registered in the name of
a person other than the signer of this Letter of Transmittal, the boxes labeled
"Special Delivery Instructions" and/or "Special Issuance Instructions" on this
Letter of Transmittal should be completed.
 
     8. WAIVER OF CONDITIONS. Total reserves the absolute right in its sole
discretion to waive the condition of the exchange offer, in whole or in part, to
the extent permitted by applicable law.
 
     9. IMPORTANT TAX INFORMATION; SUBSTITUTE FORM W-9 AND SUBSTITUTE FORM
W-8. Under United States federal income tax law, a holder whose tendered
PetroFina ADSs are accepted for exchange must provide the US Exchange Agent (as
payor) with (i) such holder's correct Taxpayer Identification Number ("TIN") on
Substitute Form W-9 below or (ii) in the case of certain exempt foreign persons,
the Substitute Form W-8 below. If the US Exchange Agent is not provided with the
correct TIN or an adequate basis for exemption, the holder may be subject to a
$50 penalty imposed by the Internal Revenue Service (the "IRS") in addition to
backup withholding in an amount equal to 31% of the gross proceeds resulting
from the exchange offer.
 
     Certain holders (including, among others, all corporations and certain
foreign individuals) are exempt from these backup withholding requirements.
Certain foreign persons can qualify for this exemption by submitting a Form W-8
or Substitute Form W-8 below, signed under penalties of perjury and attesting to
such person's exempt status.
 
     If backup withholding applies, the US Exchange Agent is required to
withhold 31% of the gross proceeds payable to a stockholder or other payee
pursuant to the exchange offer. Backup withholding is not an additional tax.
Rather, the tax liability of persons subject to backup withholding will be
reduced by the amount of tax withheld. If withholding results in overpayment of
taxes, a refund may be obtained from the IRS.
 
     The box in Part 2 of the Substitute Form W-9 may be checked if the
tendering holder has not been issued a TIN and has applied for a TIN or intends
to apply for a TIN in the near future. If the box in Box 2 is checked, the
holder or other payee must also complete the Certificate of Awaiting Taxpayer
Identification Number below in order to avoid backup withholding. Even if the
box in Part 2 is checked and the Certificate of Awaiting Taxpayer Identification
Number is completed, the US Exchange Agent will withhold 31% of all reportable
payments made prior to the time a properly certified TIN is provided to the US
Exchange Agent. Such amounts will be refunded to such holder if a properly
certified TIN is provided to the US Exchange Agent within 60 days.
 
     If the ADR(s) representing PetroFina ADSs are in more than one name or are
not in the name of the actual owner, consult the enclosed guidelines for
information on which TIN to report.
 
     Holders of PetroFina ADSs who acquired shares at different times may have
different tax bases in their PetroFina ADSs and may wish to consult with their
own tax advisors as to the possibility of identifying the specific PetroFina
ADSs surrendered in the exchange offer in order to establish the basis of the
Total Shares received in exchange therefor.
 
     IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A MANUALLY SIGNED FACSIMILE
THEREOF) TOGETHER WITH SHARE CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER
AND ALL OTHER REQUIRED DOCUMENTS MUST BE RECEIVED BY THE US EXCHANGE AGENT, OR A
NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE US EXCHANGE AGENT, PRIOR
TO THE EXCHANGE OFFER EXPIRATION DATE. STOCKHOLDERS ARE ENCOURAGED TO RETURN A
COMPLETED SUBSTITUTE FORM W-9 OR SUBSTITUTE FORM W-8 WITH THEIR LETTER OF
TRANSMITTAL.

on Substitute Form W-9 and Substitute Form W-8 may be directed to the

     11. LOST, DESTROYED OR STOLEN CERTIFICATES. If any PetroFina ADR evidencing
PetroFina ADSs has been lost, destroyed or stolen, the holder thereof should
promptly notify the US Exchange Agent by checking the box immediately following
the Special Issuance Instructions -- Special Delivery Instructions boxes and
indicating the number of PetroFina ADSs evidenced by such lost, destroyed or
stolen PetroFina ADRs. The holder thereof will then be instructed as to the
steps that must be taken in order to replace such PetroFina ADRs. This Letter of
Transmittal and related documents cannot be processed until the procedures for
replacing lost, destroyed or stolen PetroFina ADRs have been followed.
 
     12. HOLDERS OF PETROFINA SHARES NOT REPRESENTED BY PETROFINA ADSS. Holders
of PetroFina shares have been sent a Certificated Share Delivery Instruction
Form with the Prospectus and may not accept the exchange offer in respect of
PetroFina shares pursuant to this Letter of Transmittal, except insofar as those
shares are represented by PetroFina ADSs. If any holder of PetroFina shares
which are not represented by PetroFina ADSs needs to obtain a copy of a
Certificated Share Delivery Instruction Form, such holder should contact
Mackenzie Partners, Inc., at the appropriate address and telephone number set
forth in the Prospectus.
 
     13. FRACTIONAL ENTITLEMENTS. Fractional shares of Total securities will not
be issued to holders of PetroFina ADSs, but will be aggregated and sold in the
market and the net proceeds of the sale will be paid to such holders entitled
thereto.

"nonresident alien individual" means an individual who is neither a United
States citizen nor resident. Generally, an alien is considered to be a United
States resident if:
 
        The individual was a lawful permanent resident of the United States at
    any time during the calendar year, that is the alien held an immigrant visa
    (a "green card"), or
 
        The individual was physically present in the United States on:
 
           (1) at least 31 days during the calendar year, and
 
           (2) 183 days or more during the current year and the two preceding
       calendar years (counting all the days of physical presence in the current
       year, one-third the number of days of presence in the first preceding
       year, and one-sixth of the number of days in the second preceding year).
 
    EXEMPT FOREIGN PERSON: If you do not meet the requirements of certification
number two or three above, you may instead certify on Internal Revenue Service
Form 1001, Ownership, Exemption, or Reduced Rate Certificate, that your country
has a tax treaty with the United States that exempts your transactions from
United States tax.

BY MEANS OF THIS LETTER OF TRANSMITTAL. If you hold PetroFina Shares you may

     Delivery of a Letter of Transmittal, PetroFina Warrant certificates (or a
book-entry transfer of such Warrants) and any other required documents to the US
Exchange Agent by PetroFina Warrant holders will be deemed an acceptance of the
exchange offer by such holder with respect to such PetroFina Warrants subject to
the terms and conditions set out in the Prospectus and this Letter of
Transmittal.
 
     If delivery of PetroFina warrants is to be made by book-entry transfer to
an account maintained by the US Exchange Agent at The Depository Trust Company
pursuant to the procedures for book-entry transfer set forth in "Terms and
Conditions of the Exchange Offer -- Book-Entry Transfer" in the Prospectus, then
either this Letter of Transmittal or an Agent's Message (as defined below)
should be used.
 
     The term "Agent's Message" means a message, transmitted by The Depository
Trust Company and received by the US Exchange Agent and forming a part of a
Book-Entry Confirmation, which states that The Depository Trust Company has
received an express acknowledgment from the participant in The Depository Trust
Company tendering the PetroFina Warrants which are the subject of such
Book-Entry Confirmation that such participant has received and agrees to be
bound by the terms of the Letter of Transmittal.

Ladies and Gentlemen:
 
     The undersigned acknowledges that such person has received and reviewed the
Prospectus, dated May 6, 1999 (the "Prospectus"), of Total, a societe anonyme
organized under the laws of the Republic of France ("Total"), and this Letter of
Transmittal, which together with any amendments or supplements hereto or thereto
constitute the offer of Total (collectively, the "Exchange Offer") to exchange
PetroFina securities for Total securities. Unless otherwise defined in this
Letter of Transmittal, capitalized terms used herein have the meaning set forth
in the Prospectus.
 
     The undersigned hereby instructs the US Exchange Agent to accept the
exchange offer on behalf of the undersigned with respect to the PetroFina
Warrants specified in the box entitled "Description of PetroFina Warrants
Tendered," subject to the terms and conditions of the exchange offer, by
informing Total in writing that the exchange offer has been so accepted. The
undersigned hereby acknowledges that delivery of this Letter of Transmittal, the
tendered PetroFina Warrants (or book-entry transfer of such PetroFina Warrants)
and any other required documents to the US Exchange Agent by a holder of
PetroFina Warrants will be deemed (without any further action by the US Exchange
Agent to constitute acceptance of the exchange offer by such holder in respect
of such holder's PetroFina Warrants, subject to the terms and conditions of the
exchange offer.
 
     The undersigned understands that acceptance of the exchange offer by the
undersigned pursuant to the procedures described herein and in the instructions
hereto, subject to the withdrawal rights described in the Prospectus, will
constitute a binding agreement between the undersigned and Total upon the terms
and subject to the conditions of the offer.
 
     The undersigned hereby delivers to the US Exchange Agent the
above-described PetroFina Warrants for which the exchange offer is being
accepted, in accordance with the terms and conditions of the exchange offer,
receipt of which is hereby acknowledged.
 
     Upon the terms of the exchange offer (including, if the offer is revised,
varied, extended or renewed, the terms or conditions of any such revision,
variation, extension, or renewal), and effective at the time that the condition
to the exchange offer has been satisfied, fulfilled or, where permitted, waived
(at which time Total will give notice thereof to the US Exchange Agent), and if
he or she has not validly withdrawn his or her acceptance, the undersigned
hereby sells, assigns and transfers to, or upon the order of, Total all right,
title and interest in and to all PetroFina Warrants with respect to which the
exchange offer is being accepted (and any and all PetroFina Warrants or other
securities or rights issuable in respect of such PetroFina Warrants) and
irrevocably constitutes and appoints the US Exchange Agent the true and lawful
agent and attorney-in-fact of the undersigned with respect to such PetroFina
Warrants (and any such other PetroFina Warrants, securities or rights), with
full power of substitution (such power of attorney being deemed to be an
irrevocable power coupled with an interest), to (a) deliver such PetroFina
Warrants (and any such other PetroFina Warrants, securities or rights), or
accept transfer of ownership of such PetroFina Warrants (and any such other
PetroFina Warrants, securities or rights) on the account books maintained by The
Depository Trust Company together, in any such case, with all accompanying
evidences of transfer and authenticity, to, or upon the order of Total, and (b)
receive all benefits and otherwise exercise all rights of beneficial ownership
of such PetroFina Warrants (and any such other PetroFina Warrants, securities or
rights), all in accordance with the terms of the exchange offer.
 
     The undersigned hereby represents and warrants that the undersigned has
full power of authority to accept the exchange offer and to tender, exchange,
sell, assign and transfer the PetroFina Warrants in respect of which the
exchange offer is being accepted or deemed to be accepted (and any and all other
PetroFina Warrants, securities or rights issued or issuable in respect of such
PetroFina Warrants) and Total will acquire good title thereto, free from all
liens, equities, charges, encumbrances and other interests and together with all
rights now or hereafter attaching thereto. The undersigned will, upon request,
execute any additional documents deemed by the US Exchange Agent or Total to be
necessary or desirable to complete the sale, assignment and transfer of the
PetroFina Warrants in respect of which the exchange offer is being accepted (and
any and all other PetroFina Warrants, securities or rights).

     The undersigned irrevocably undertakes, represents, and warrants to and
agrees with Total (so as to bind him or her, his or her personal
representatives, heirs, successors and assigns) to the effect that the

Acceptance Form or any related documents in, into or from Canada, or any

sending of such documents is prohibited by applicable law, (ii) is accepting the
exchange offer from outside Canada, or any jurisdiction into which the sending
of such documents is prohibited by applicable law, and (iii) is not an agent or

applicable law.
 
     All authority herein conferred or agreed to be conferred pursuant to this
Letter of Transmittal shall be binding upon the successors, assigns, heirs,

undersigned. Except as stated in the Prospectus, this acceptance is irrevocable.
 
     Unless otherwise instructed under "Special Issuance Instructions" below,
the undersigned hereby instructs the US Exchange Agent to register the Total
Warrants to which the undersigned is entitled in the name(s) of the holder(s)
shown above under "Description of PetroFina Warrants Tendered." Unless otherwise
instructed under "Special Delivery Instructions" below, the undersigned hereby

PetroFina Warrants in respect of which the exchange offer is not being accepted
or which are not exchanged (and accompanying documents, as appropriate) and/or
deliver the certificates representing the Total Warrants to be delivered to the
undersigned pursuant to the exchange offer to the address(es) of the registered
holder(s) appearing above under "Description of PetroFina Warrants Tendered." In
the case of a book-entry delivery of PetroFina Warrants, the undersigned hereby
instructs the US Exchange Agent to credit the account maintained at The
Depository Trust Company with any PetroFina Warrants in respect of which the
exchange offer is not being accepted or which are not purchased. The undersigned
recognizes that the US Exchange Agent will not transfer any PetroFina Warrants
which are not purchased pursuant to the exchange offer from the name of the
registered holder thereof to any other person.
 
     SUBJECT TO THE TERMS OF THE PROSPECTUS, THIS LETTER OF TRANSMITTAL SHALL
NOT BE CONSIDERED COMPLETE AND VALID, AND DELIVERY OF TOTAL WARRANTS PURSUANT TO
THE EXCHANGE OFFER SHALL NOT BE MADE, UNTIL THE PETROFINA WARRANTS IN RESPECT OF
WHICH THE EXCHANGE OFFER IS BEING ACCEPTED AND ALL OTHER REQUIRED DOCUMENTATION

     If any of the PetroFina Warrants in respect of which the exchange offer is
being accepted hereby are owned of record by two or more owners, all such owners
must sign this Letter of Transmittal.
 
     If any of the PetroFina Warrants in respect of which the exchange offer is
being accepted are registered in different names on different PetroFina
Warrants, it will be necessary to complete, sign and submit as many separate
Letters of Transmittal as there are different registrations of PetroFina
Warrants.
 
     If this Letter of Transmittal or any PetroFina Warrants or stock powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and proper evidence
satisfactory to Total of their authority so to act must be submitted.
 
     When this Letter of Transmittal is signed by the registered holder(s) of
the PetroFina Warrants listed and transmitted hereby, no endorsements of
certificates are required. Signatures on such PetroFina Warrants or stock powers
must be guaranteed by an Eligible Institution.
 
     If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the PetroFina Warrants listed, the PetroFina Warrants
must be endorsed or accompanied by appropriate stock powers signed exactly as
the name(s) of the registered holder(s) appear(s) on the PetroFina Warrants.
Signatures on such PetroFina Warrant or stock powers must be guaranteed by an
Eligible Institution.
 
     6. STOCK TRANSFER TAXES. Total will pay or cause to be paid any stock
transfer taxes with respect to the transfer and sale to it or its order of
PetroFina Warrants pursuant to the exchange offer. If, however, delivery of any
of the consideration payable pursuant to the exchange offer is to be made to any
persons other than the registered holder(s), or if PetroFina Warrants in respect
of which the exchange offer is being accepted are registered in the name of any
person other than the person(s) signing this Letter of Transmittal, the amount
of any stock transfer taxes (whether imposed on the registered holders(s) or
such person(s)) payable on account of the transfer to such person will be
deducted from the purchase price (or new Total Warrants will be withheld) unless
satisfactory evidence of the payment of such taxes or exemption therefrom is
submitted.
 
     Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the PetroFina Warrants listed in this
Letter of Transmittal.

     7. SPECIAL DELIVERY INSTRUCTIONS. If any PetroFina Warrants in respect of
which the exchange offer is not being accepted or which are not purchased are to
be returned to a person other than the signer of this Letter of Transmittal or
to an address other than that shown in the box entitled "Description of
PetroFina Warrants Tendered" on the first page of this Letter of Transmittal,
should be completed.
 
     8. WAIVER OF CONDITIONS. Total reserves the absolute right in its sole
discretion to waive any of the specified condition of the exchange offer, in
whole or in part, to the extent permitted by applicable law.
 
     9. IMPORTANT TAX INFORMATION; SUBSTITUTE FORM W-9 AND SUBSTITUTE FORM
W-8. Under United States federal income tax law, a holder whose tendered
PetroFina Warrants are accepted for exchange must provide the US Exchange Agent
(as payor) with (i) such holder's correct Taxpayer Identification Number ("TIN")
on Substitute Form W-9 below or (ii) in the case of certain exempt foreign
persons, the Substitute Form W-8 below. If the US Exchange Agent is not provided
with the correct TIN or an adequate basis for exemption, the holder may be
subject to a $50 penalty imposed by the Internal Revenue Service (the "IRS") in
addition to backup withholding in an amount equal to 31% of the gross proceeds
resulting from the exchange offer.
 
     Certain holders (including, among others, all corporations and certain
foreign individuals) are exempt from these backup withholding requirements.
Certain foreign persons can qualify for this exemption by submitting a Form W-8
or Substitute Form W-8 below, signed under penalties of perjury and attesting to
such person's exempt status.
 
     If backup withholding applies, the US Exchange Agent is required to
withhold 31% of the gross proceeds payable to a Warrant holder or other payee
pursuant to the exchange offer. Backup withholding is not an additional tax.
Rather, the tax liability of persons subject to backup withholding will be
reduced by the amount of tax withheld. If withholding results in overpayment of
taxes, a refund may be obtained from the IRS.
 
     The box in Part 2 of the Substitute Form W-9 may be checked if the
tendering holder has not been issued a TIN and has applied for a TIN or intends
to apply for a TIN in the near future. If the box in Box 2 is checked, the
holder or other payee must also complete the Certificate of Awaiting Taxpayer
Identification Number below in order to avoid backup withholding. Even if the
box in Part 2 is checked and the Certificate of Awaiting Taxpayer Identification
Number is completed, the US Exchange Agent will withhold 31% of all reportable
payments made prior to the time a properly certified TIN is provided to the US
Exchange Agent. Such amounts will be refunded to such holder if a properly
certified TIN is provided to the US Exchange Agent within 60 days.
 
     If the PetroFina Warrants are in more than one name or are not in the name
of the actual owner, consult the enclosed guidelines for information on which
TIN to report.
 
     IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A MANUALLY SIGNED FACSIMILE
THEREOF) TOGETHER WITH WARRANT CERTIFICATES AND ALL OTHER REQUIRED DOCUMENTS
MUST BE RECEIVED BY THE US EXCHANGE AGENT, OR A NOTICE OF GUARANTEED DELIVERY
MUST BE RECEIVED BY THE US EXCHANGE AGENT, PRIOR TO THE OFFER EXPIRATION DATE.
WARRANT HOLDERS ARE ENCOURAGED TO RETURN A COMPLETED SUBSTITUTE FORM W-9 OR
SUBSTITUTE FORM W-8 WITH THEIR LETTER OF TRANSMITTAL.
 
     10. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions and requests
for assistance or additional copies of the Prospectus, this Letter of
Transmittal, the Notice of Guaranteed Delivery and the Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 and
Substitute Form W-8 may be directed to the Information Agent at the address and
telephone number set forth below.
 
     11. LOST, DESTROYED OR STOLEN CERTIFICATES. If any PetroFina Warrants have
been lost, destroyed or stolen, the holder thereof should promptly notify the US
Exchange Agent by checking the box immediately following the Special Issuance
Instructions -- Special Delivery Instructions boxes and indicating the number of
PetroFina Warrants lost, destroyed or stolen. The holder thereof will then be
instructed as to the steps that must be taken in order to replace such PetroFina
Warrants. This Letter of Transmittal and
 
                                       10

     12. HOLDERS OF PETROFINA SHARES. Holders of PetroFina shares [have been
sent a Certificated Share Delivery Instruction Form with the Prospectus] and may

Letter of Transmittal. If any holder of PetroFina shares needs to obtain a copy
of a Certificated Share Delivery Instruction Form, such holder should contact

Board of Directors
PETROFINA S.A
Rue de l'Industrie 52
B-1040 Bruxelles


Dear Sirs,

        You have requested our opinion as to the fairness to the shareholders
of PETROFINA SA ("Petrofina") of the public tender offer proposed by TOTAL SA
("Total") following the "convention d'apports en nature" agreement signed on
December 1, 1998 between Total and Electrafina, Compagnie Nationale a
Portefeuille (Fibelpar(3)), Tractebel, Electrabel and Fortis (AG1824) in
respect of Petrofina shares held by these last five companies to be exchanged
for shares in Total (the "Exchange Agreement"). The Exchange Agreement was
ratified by Total at its extraordinary shareholders meeting held on January 14,
1999. The proposed exchange ratio is nine (9) new Total shares with dividend
rights as of January 1, 1998 for two (2) shares issued by Petrofina (with
"coupons" n degree 16 and following attached).


The terms of the exchange offer made by Total to Petrofina shareholders as
outlined in the preliminary prospectus in respect of its public exchange offer
("the Offer") dated March 31, 1999 and its draft F-4 Form pre-filed with the
Securities and Exchange Commission in Washington DC on March 30, 1999, which
are the subject of our fairness opinion are as follows : for every two (2)
Petrofina shares (with "coupons" n degree 16 and following attached), tendered
pursuant to the Offer, the holder thereof will receive from Total nine (9)
Total shares (with dividend rights as of January 1, 1998) and nine (9) Total
VVPR-Strips. The Offer is also made in respect of Petrofina shares to be issued
upon conversion of warrants issued in 1997 and held by employees of Petrofina
and certain subsidiaries and those issued in 1998 in connection with the merger
of Petrofina and Fina, Inc.


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

(3) Between the date of the signature of the Exchange Agreement and the
completion of the exchange, Fibelpar has transferred all its shares in
Petrofina to Investor.

Paribas, as part of its investment banking business, is regularly requested to
make valuations of companies business activities and securities in connection
with mergers and acquisitions, equity offerings and private placements. We are
familiar with both Petrofina and Total. Petrofina has given us a mandate to act
as its advisor in connection with the Offer. We have in the past acted in
various advisory capacities for several companies which are part of the
Compagnie Nationale a Portefeuille group. We also advised or acted on behalf of
Total in various occasions: in particular we acted in various advisory and
other capacities in connection with previous share offerings. The Chairman of
the Supervisory Board of Paribas is a member of  the Board of Directors of
Total. The Chairman and Chief Executive Officer of Total is a member of the
Supervisory Board of Paribas.



In connection with this opinion, we have reviewed, among other documents, the
terms of the public exchange offer to Petrofina shareholders, dated March 31,
1998 ; the Exchange Agreement dated December 1, 1998; the report of the
independent experts ("commissaire aux apports") in respect of the value of the
Petrofina shares dated January 4, 1999; annual reports of both companies for
the last six financial years ; certain interim reports; the prospectus in
respect of the listing of Petrofina shares on the New York Stock Exchange in
1997; certain management reports on expected trends concerning the activity of
Petrofina. We also had several meetings with Petrofina's management regarding
Petrofina's past and current activities, its financial situation, its
prospects, and the synergies that the merger with Total are expected to create.
We also had some meetings with Total in which Total provided information which
was publicly available. In addition, we have reviewed the share prices and
trading activity in the shares of both companies on the relevant stock
exchanges since the announcement of the operation, compared stock market
information on both companies with information relating to major comparable
listed companies, analysed certain recent transactions in the oil and gas
sector which are similar with this transaction and performed other studies and
analyses as we considered appropriate. In connection with this opinion, we did
not have access to either the valuation reports prepared by Total's advisors or
to Total's business plan.


We have not verified or made independent inquiries in respect of the accuracy
or completeness of any written or other information transmitted to us by
Petrofina or Total for the purpose of this opinion, have relied on the
confirmation by the management of both companies that there were no significant
liabilities in respect of either company which were not disclosed to us.


In addition, we have not made an independent evaluation or appraisal of the
assets and liabilities of the two companies, and Petrofina and Total did not
furnish any such evaluation or appraisal.





                                     - 2 -
<PAGE>   70
We have received from you an affirmation letter in which you consider that you
have brought to our attention all the information in your possession necessary
in order for us to execute our mandate and to provide this opinion.


Based upon the information provided and the evaluation we have performed, and
subject to the foregoing, it is our opinion that, as of the date hereof, the
terms of the Offer proposed by Total to Petrofina's shareholders is fair from a
financial perspective.


In addition, Paribas, on the basis of the various documents it has examined,
has made a comparison between the financial terms of the Exchange Agreement
made by certain shareholders of Petrofina and the financial terms of the Offer
as it has been proposed by Total and considers that there is no difference
between the two.




This fairness opinion is addressed to the Board of Directors of Petrofina to
assist it in the formulation of the statement it has to release in respect of
the Offer ; this fairness opinion does not constitute a recommendation to the
shareholders of Petrofina to accept Total's exchange offer. Furthermore, we are
not expressing any opinion herein as to the prices at which the shares of
Total-Fina will trade when the merger becomes effective.


We remain,


Yours sincerely,





Thierry DORMEUIL                                            Alain RAUSCHER

Gentlemen:

You have requested our opinion as to the fairness, from a financial point of
view, to the shareholders of PetroFina S.A. (the "Company") of the exchange
ratio to be applied in respect of the tender offer (the "Tender Offer") by
Total S.A. (the "Buyer") for the common stock of the Company under the terms of
which 2 shares of common stock of the Company will be exchanged for 9 ordinary
shares of Total (the "Exchange Ratio").  In addition, the Company's
shareholders as of January 13, 1999 have received a dividend of BEF460 per
share and are entitled to a dividend for 1998 from Total on the shares to be
newly issued as a result of the exchange offer.

On January 14, 1999 the Buyer acquired (subject to certain conditions
precedent) a 41% stake in the Company from Electrafina, Fibelpar, Tractebel,
Electrabel and AG 1824 (the "Contributing Shareholders") through the
contribution of the shares held by the Contributing Shareholders against new
shares to be issued by the Buyer ("the Contribution" and, together with the
Tender Offer, the "Transaction").  Under Belgian law, the Contribution
triggered the obligation for the Buyer to propose to all remaining shareholders
in the Company an exchange offer under the same terms, such offer being
described in the Public Offer Document submitted to the Commission bancaire et
financiere ("CBF") on the 31 March, 1999 (the "Belgian Prospectus") and the
draft of F-4 Registration Statement pre-notified to the Securities and Exchange
Commission on the 30 March, 1999, (the "US Prospectus" together with the
Belgian Prospectus, the "Prospectuses").

Please be advised that while certain provisions of the Transaction are
summarized above, the terms of the Transaction are more fully described in the
Prospectuses.  As a result, the description of the Transaction and all other
information contained herein is qualified in its





                                     - 1 -
<PAGE>   72
entirety by reference to the more detailed information appearing or
incorporated by reference in the Prospectuses.

In arriving at our opinion, we have reviewed (i) the terms of the Tender Offer
as presented in the Prospectuses; (ii) certain publicly available information
concerning the business of the Buyer, the Company and certain other companies
engaged in businesses comparable to those of the Buyer and the Company, and the
reported market prices for certain other companies' securities deemed
comparable; (iii) publicly available terms of certain transactions comparable
to the Transaction; (iv) current and historical market prices of the securities
of the Buyer and the Company; (v) the audited financial statements of the
Company and the Buyer for the fiscal year ended December 31, 1998 and December
31, 1997; (vi) certain presentations made by the Company and the Buyer in 1998
and in 1999 to equity analysts regarding the performance of their respective
businesses and potential synergies that may be realized if the Tender Offer is
successful; (vii) the schedule to the report submitted by the Total Board of
Directors to the combined extraordinary and ordinary shareholders' meeting of
14 January 1999; (viii) the Independent Valuation Auditors' Report from
Dominique Ledouble and Rene Ricol dated January 4, 1999, (ix) Minutes of a
meeting of the Company's General Meeting of Shareholders, held on January 4,
1999 which authorized the payment of a dividend of BEF 460 per share; (x) the
documents relating to the Contribution, such documents being the "Protocole
d'Accord General", dated 1st December, 1998, the "Convention d'Apports en
Nature" dated 1st December, 1998 and the "Protocole d'Accord Electrafina" dated
1st December, 1998.  The foregoing documents in sub-paragraph (x), which are
referred to as the "Contribution Documents" have been made available to us by
the Buyer.

In addition, we have participated in discussions with certain members of the
management of the Company and the Buyer with respect to certain aspects of the
Tender Offer, the past and current business operations of the Company and the
Buyer, the financial condition and future prospects and operations of the
Company and certain other matters we believed necessary or appropriate to our
inquiry.  We have in addition reviewed such other financial studies and
analyses and considered such other information as we deemed appropriate for the
purposes of this opinion.

In performing our analysis, we have used such valuation methodologies as we
have deemed necessary or appropriate for the purposes of this opinion.  Our
view is based on (i) our consideration of the information the Company and the
Buyer have supplied to us to date, (ii) our understanding of the terms upon
which the Buyer intends to consummate the Tender Offer, (iii) the current
capital structure of the Company and the Buyer, and (iv) the consummation of
the Tender Offer within the time periods contemplated by the Prospectuses.

In giving our opinion, we have relied upon and assumed, without independent
verification, the accuracy and completeness of all information that was
publicly available or was furnished to us by the Company and the Buyer or
otherwise reviewed by us, and we have not assumed any responsibility or
liability therefor.  In particular we have assumed, based on assurances we have
received from the management of the Buyer, that (a) other than the Contribution
Documents, there are no documents, arrangements or agreements, whether written
or verbal, between the





                                     - 2 -
<PAGE>   73
Buyer and any other party, including the Contributing shareholders and any
other party to any of the Contribution Documents, in respect of or in
connection with the Contribution or the Tender Offer, and (b) the Contribution
Documents in the form we reviewed fully and fairly set out and represent all
arrangements and agreements between the parties thereto in respect of the
Contribution or the Tender Offer.

We have not conducted any evaluation or appraisal of any assets or liabilities,
nor have any such evaluations or appraisals been provided to us.  In relying on
financial analyses provided to us of potential synergies that may be realized
from the Tender Offer, we have assumed that they have been reasonably prepared
based on assumptions reflecting the currently available estimates and judgments
by management as to such potential synergies.  There will necessarily be
differences in the tax treatment to shareholders of the Company of the Tender
Offer, based on inter alia the tax residence and the status as legal or natural
person of each shareholder, and we have therefore not considered, and do not
opine upon, any differences in the benefits of the Tender Offer that may exist
between the shareholders of the Company due to differences in their respective
tax situation and condition.

Our opinion is necessarily based on economic, market and other conditions as in
effect on, and the information made available to us as of, the date hereof.  It
should be understood that subsequent developments may affect this opinion and
that we do not have any obligation to update, revise, or reaffirm this opinion.
It is our belief, based on our review of the Contribution Documents that have
been provided to us and on our assumption that there are no other relevant
documents, and based on the further assumptions set out herein, that the
Exchange Ratio to be offered to the shareholders of the Company in the proposed
Tender Offer is no less favorable, from a financial point of view, than the
financial terms and conditions of the Contributions entered into between the
Buyer and the Contributing Shareholders.  We are expressing no opinion herein
as to the price at which any of the Company's or the Buyer's securities will
trade at any future time.  Similarly, as indicated above, we are expressing no
opinion herein as to the tax or accounting treatment for any of the Company or
its shareholders as a result of the Tender Offer.

We have acted as financial advisor to the Board of Directors of the Company
with respect to the proposed Tender Offer and will receive a fee from the
Company for our services.  As you are aware, in the past we have provided
financial advisory services to both the Company and the Buyer.  In the ordinary
course of their businesses, our affiliates may actively trade the debt and
equity securities of the Company and the Buyer for their own accounts or for
the account of customers and, according, they may at any time hold long or
short positions in such securities. J.P. Morgan has in place internal policies
on conflict of interest and internal procedures on sharing of information.

This opinion may not be used for any other purpose, disclosed, summarized,
quoted or referred to at any time and in any manner without prior written
consent, save that we hereby consent to (a) a reference, in the Belgian
Prospectus to be issued in connection with the Tender Offer, to this





                                     - 3 -
<PAGE>   74
letter, and the fact that the Board of Directors of the Company took it into
account and (b) disclosure of this opinion in the US Prospectus.

In addition, J.P. Morgan was not requested to and did not provide advice
concerning the structure of the Tender Offer, or provide services other than
the delivery of this opinion.  J. P. Morgan was not authorized to and did not
solicit any expressions of interest from any other parties with respect to the
sale of all or any part of the securities of the Company.  J.P. Morgan did not
participate in negotiations with respect to the terms of the Tender Offer and
related transactions. Consequently, no opinion is expressed whether any
alternative transaction might product consideration for holders of the
Company's securities in an amount in excess of that contemplated in the Tender
Offer.

On the basis of and subject to the foregoing, it is our opinion as of the date
hereof that the Exchange Ratio to be offered to the shareholders of the Company
in the proposed Tender Offer is fair, from a financial point of view, to the
shareholders of the Company.

This letter is provided solely for the benefit of the Board of Directors of the
Company in connection with and for the purposes of its evaluation of the Tender
Offer.  This opinion does not constitute a recommendation to any stockholder of
the Company as to how such stockholder should vote with respect to the Tender
Offer and may not be relied upon by any other person.

Very truly yours,


MORGAN GUARANTY TRUST COMPANY OF NEW YORK

4.1      That to the best of their knowledge they may undertake and execute the

(a)      expiration of the waiting period provided for by the American
         Hart-Scott-Rodino Antitrust Improvements Act;

(b)      authorization by the competent European authorities under EC Council
         Regulation No. 4064/89 regarding the control of concentration
         operations between enterprises;

null and void due to failure of the conditions precedent, except if at the end
of a bona fide consultation, the Companies and TOTAL reach an agreement no

deadline required to obtain the approval of said authorities. Assuming such an
agreement, said commitments by the Companies would remain in full effect.

                                                        PARTY OF THE SECOND PART

         (the Companies and TOTAL are hereinafter collectively referred to as
the "PARTIES"),

WHEREAS:

         The Companies are shareholders of PETROFINA, a corporation under
Belgian law with stated capital of BEF 43,605,279,966 divided into 23,459,772
shares without par value, to which could be added 511,255 shares that might be
created by the exercise of various warrants issued by PETROFINA, admitted to
the official listing of the Brussels Stock Exchange and other financial
centers, with registered office in B- 1040 BRUSSELS, 52, rue de l'Industrie,
registered in the Commercial Register of Brussels under No.  227,597
(hereinafter referred to as "PETROFINA").

         The number of PETROFINA shares held by the Companies on the date of
these presents is as follows:

         5,304,018 shares held by ELECTRAFINA;

         referred to as the "SHARES").

         The Parties have sought a mutual rapprochement in order to implement

acquire the Shares held by the Companies. This acquisition will take the form
of contributions in kind, subject to French law, and will be compensated by new
shares of TOTAL ("NEW TOTAL SHARES") under the terms and conditions described
below, whereby the Companies will become shareholders of TOTAL as a result of
these contributions.

<PAGE>   90
         As soon as the contributions, which are the subject of the
Contribution Agreement, have been made, TOTAL will file a notice of a public
exchange offer ("OPE") for the entirety of the shares and, if necessary,
PETROFINA securities equivalent thereto within the meaning of Article 1,
Section 3 of the Royal Decree of November 8, 1989, which are not owned by the
Companies, under the same terms as those offered to the Companies.

         These operations fall within the scope of an industrial rapprochement
between TOTAL and PETROFINA and the purpose of this Memorandum is to clarify
this scope.

NOW THEREFORE IT IS HEREBY AGREED AS FOLLOWS:

TITLE I  -  IMPLEMENTATION OF RAPPROCHEMENT TRANSACTIONS

Article 1.       Signature of Agreement between the Parties for Contributions
in Kind

1.1      To implement the first stage of the industrial rapprochement described
         above, the parties are signing today the Contribution Agreement
         attached as Attachment 1 (hereinafter referred to as "CONTRIBUTION
         AGREEMENT").

1.2      The Board of Directors of TOTAL called a Mixed General Meeting of its
         shareholders on November 30, 1998, notably to approve the contribution
         transaction by the Companies and the corresponding increase in TOTAL's
         capital under the terms of the notice of meeting, which is attached to
         these presents as Attachment 2.  The Board of Directors furthermore
         decided the launching of the OPE and has delegated the necessary
         powers to its Chairman to implement it.

1.3      The report by the Board of Directors of TOTAL to the General Meeting
         of its shareholders, in which it recommends, in particular, the
         approval described in Paragraph 1.2 above, is attached to these
         presents as Attachment 3.

1.4      The parties agree that in the event that the General Meeting of the
         shareholders of TOTAL should fail to approve by February 17, 1999, the
         contributions and the corresponding compensation set forth in the
         Contribution Agreement, TOTAL shall pay to the Companies a
         non-revisable sum of US$ 100,000,000, exclusive of any other sum
         whatsoever, in consideration of the immobilization of the shares,
         which are the subject of the Contribution Agreement. This sum is to be
         distributed among them in proportion to the PETROFINA shares to be
         contributed by each. This clause shall not be construed as a right to
         a penalty for any of the parties.

Article 2.       Launching of an OPE by TOTAL for the PETROFINA Shares

2.1      As soon as the contributions, which are the subject of the
         Contribution Agreement, have been made, TOTAL will file the notice and
         documents with the Belgian Banking and Finance Commission, as
         specified in Articles 4 and 5 of the Royal Decree of November 8, 1989,
         regarding take-over bids and changes in the control of companies,
         required to launch an OPE for the entirety of the shares forming the
         capital of PETROFINA that are not owned by the Companies and, if
         required, securities equivalent thereto within the meaning of Article
         1, Section 3 of the Royal Decree of November 8, 1989, that are not
         owned by the Companies.

2.2      Within the context of the OPE, two (2) common PETROFINA shares
         contributed to the OPE are planned to be exchanged for nine (9) new
         common TOTAL shares with dividend rights as of January 1, 1998 (i.e.,
         providing the right to all dividends paid for fiscal year 1998). TOTAL
         shall have the right to the dividends paid for fiscal year 1998 by
         PETROFINA, except for a one-time interim dividend for fiscal year 1998
         of BEF 460 per share of PETROFINA to be decided by the Board of
         Directors for the benefit of its shareholders, or any other equivalent
         formula for the shareholders' benefit.

         The terms of the OPE to be launched shall be the same as those for the
         contributions made in accordance with the Contribution Agreement.

2.3      The opening of this OPE will be subject to the approval by the Belgian
         Banking and Finance Commission and the competent European Authorities
         under (EC) Council Regulation No. 4064/89 regarding control of
         concentration operations between enterprises and by the competent
         American authorities under the American Hart-Scott-Rodino Antitrust
         Improvements Act.

Article 3.       Failure of Conditions Precedent and Consultation among the
Parties

The approvals by the competent European authorities under (EC) Council
Regulation No. 4064/89 regarding control of concentration operations between
enterprises and by the competent American authorities under the
Hart-Scott-Rodino Antitrust Improvements Act must be obtained within a period
of 3 months from the date when said authorities are notified of the operation.
TOTAL shall complete such notifications by December 18, 1998 at the latest. If
at the end of these 3 months, the concentration has not been authorized, the
commitments by the Companies shall remain in effect for an additional period of
one month. At the end of this one-month period, the commitments by the
Companies shall become null and void due to failure of the conditions precedent
unless, at the end of a good faith consultation, the Companies and TOTAL reach
an agreement no later than fifteen days prior to the expiration of this
one-month period regarding the deadline for obtaining the approval by said
authorities. Assuming such an agreement, the Companies' commitments will remain
in full effect.

TITLE II  -  ORGANIZATION OF SYNERGIES BETWEEN TOTAL AND PETROFINA

Article 4.       General Policy of the New Group Established by TOTAL and
PETROFINA

As soon as the contribution in kind has been completed and TOTAL has obtained
control of PETROFINA within the meaning of Belgian Accounting Law, the
following actions shall be taken:

4.1      TOTAL shall implement a global development strategy that will profit
         from the resources of PETROFINA and its group. To this end. TOTAL is
         planning jointly to manage with PETROFINA their refining-distribution
         assets in order to optimize the advantages of the two entities in
         Europe. In particular, TOTAL shall ensure the continuation of the
         large Belgian industrial sites of Anvers and Feluy and pursue the
         necessary investments.

4.2      To better reflect the alliance between the two entities, TOTAL shall
         propose to the first General Meeting of its shareholders following the
         conclusion of the OPE to change the name "TOTAL" to a new name: "TOTAL
         FINA".

4.3      PETROFINA shall remain an entirely separate legal structure with its
         own corporate bodies and general management. The registered office of
         PETROFINA shall remain in Brussels. Furthermore, the seats of the
         operational general management of TOTAL FINA refining- distribution
         and petrochemicals shall be located in Brussels. Mr. Francois CORNELIS
         shall be appointed a Member and Vice-Chairman of the Executive
         Committee of TOTAL FINA.

4.4      The Board of Directors of PETROFINA shall be composed of 7 members
         appointed by TOTAL and 5 members appointed by the ELECTRAFINA Group.
         The Board of Directors of PETROFINA shall be chaired by Baron A.
         FRERE. Two Managing Directors shall be initially appointed: Mr.
         Francois CORNELIS and Mr. Jean-Paul VETTIER.

4.5      With respect to corporate issues, the planned rapprochement will be
         the subject of major consultation and will be a function of the
         development prospects of the new group. In particular, a joint policy
         of stock ownership and stock options will be implemented for the
         employees of TOTAL FINA following a study of the different systems
         currently in place at the TOTAL and PETROFINA companies.

Article 5.       Transfer

TOTAL shall not transfer the PETROFINA shares contributed by the Companies in
any form whatsoever for a period of two years from the date when such
contributions are made.

                                                        PARTY OF THE SECOND PART

(ELECTRAFINA and TOTAL are hereinafter collectively referred to as the
"PARTIES.")

WHEREAS:

1 .      ELECTRAFINA is a shareholder of PETROFINA, a corporation under Belgian
         law with stated capital of BEF 43,605,279,966 divided into 23,459,772

         law.

These operations fall under the scope of an industrial rapprochement between
TOTAL and PETROFINA and the purpose of this Agreement is to clarify the capital
relations between ELECTRAFINA and TOTAL.

NOW THEREFORE IT IS HEREBY AGREED AS FOLLOWS:

ARTICLE 1.       COMPOSITION OF THE BOARD OF DIRECTORS OF TOTAL FINA

1.1      The Board of Directors of TOTAL is currently composed of twelve (12)
         members.

         The Board of Directors of TOTAL called a Mixed General Meeting of its
         shareholders on November 30, 1998, notably to approve (i) the
         contribution operation, which is the subject of the Contribution
         Agreement, (ii) the corresponding increase in capital of TOTAL, (iii)
         the proposed appointment of three (3) new Directors, namely Baron
         Frere, Mr. Paul Desmarais, Senior, and Mr. Thierry de Rudder, and (iv)
         to proceed with the necessary amendments of the bylaws. The resolution
         by the Board of Directors of TOTAL is attached to these presents as
         Attachment 1.

         Furthermore, the Chairman of the Board of TOTAL shall use his best
         efforts to have the Board of Directors propose the appointment of one
         (1) additional director who is independent and a Belgian citizen to
         the Regular Annual General Meeting of the shareholders of TOTAL, which
         will be held in 1999 and which will pass on the financial statements
         as of December 31, 1998.

1.2      If the vote by the Regular General Meeting of the shareholders of
         TOTAL is favorable and Baron Frere is appointed director, the Chairman
         of the Board of TOTAL will use his best efforts to have the latter
         appointed Vice Chairman of the Board of Directors of TOTAL (Article 21
         of the bylaws of TOTAL will be amended for this purpose).

ARTICLE 2.       NEW TOTAL SHARES HELD BY THE ELECTRAFINA GROUP

2.1      The holding of New Shares by ELECTRAFINA is consistent in terms of
         continuity. Consequently, any planned Transfer of the New Shares, or
         any other security providing access to the capital or to the voting
         rights of TOTAL, by ELECTRAFINA (or any company of its group holding
         said securities) shall first be discussed between the Chairman of
         ELECTRAFINA and the Chairman of TOTAL.  Exempt herefrom is any
         Transfer occurring between companies affiliated with ELECTRAFINA
         within the meaning of Belgian law, which may freely take place.

2.2      For the purpose of these presents, the term "TRANSFER" means any
         transfer to any third parties to this Memorandum of Understanding by
         any legal means whatsoever, either free of charge or for valuable
         consideration and, in particular, by a transaction through the stock
         exchange or over the counter, by public or private sale, by a
         contribution to a public offer for purchase or exchange, by exchange,
         by contribution to a company, by donation, by transfer

         loan, by establishment of a guarantee by a sleeping partner agreement,
         or by transfer in case of liquidation by order of the court.

ARTICLE 3.       STABILIZATION CLAUSE

3.1      Once the operations set forth in the Contribution Agreement have been
         completed, ELECTRAFINA shall refrain from holding more than 10% of the
         share capital of TOTAL, either alone or together with GBL, or any
         company controlled by them, for the entire term of this Memorandum of
         Understanding.

3.2      In the event that ELECTRAFINA, either alone or together with GBL, or
         any company controlled by them, should hold more than the percentage
         specified in Section 3.1 above, ELECTRAFINA shall transfer a
         sufficient number of TOTAL shares to reduce its holdings to said
         percentage within thirty (30) calendar days from the date when this
         threshold was exceeded.  This shall not apply in the case where TOTAL
         buys back its own shares in order to cancel them.
