                                     PART I
ITEM 1  BUSINESS
 
     (a) FINA, Inc. (and subsidiaries, collectively the "Company" or "FINA") was
organized in 1956 as American Petrofina, Incorporated and is part of an
international group of about 166 companies in 34 countries which are affiliated
with PetroFina S.A., a publicly-held corporation organized under the laws of the
Kingdom of Belgium. Petrofina Delaware, Incorporated ("PDI") owns approximately
85% and 100% of the Class A and Class B common stock of the Company,
respectively. PetroFina S.A. owns 100% of PDI and American Petrofina Holding
Company.
 
     On February 25, 1997, the Company received a letter from PetroFina, S.A.
("PetroFina") proposing a merger transaction in which the Company would become a
wholly-owned affiliate of PetroFina. The transaction would be a negotiated
merger in which each holder of a Class A share not owned by PetroFina and its
affiliates would receive the equivalent of $60 U.S. per share in cash, PetroFina
shares or a combination of cash and PetroFina shares. PetroFina advised that it
intends to seek listing on The New York Stock Exchange of American Depositary
Receipts representing shares of PetroFina concurrently with the transaction.
Consummation of the merger would be subject, among other things, to approval of
the Board of Directors of the Company and the negotiation and execution of a
definitive merger agreement containing customary terms and conditions. In its
letter, PetroFina acknowledged that the Company may wish to consider the
proposal through a special committee of independent directors with its own
independent advisors and invited the Company's representatives to meet with
PetroFina advisors to discuss the proposal.
 
     Following receipt of the merger proposal, the Board of Directors of the
Company acting by written consent appointed a special committee of independent
directors (the "Special Committee") to review and evaluate the merger proposal
of PetroFina. The Special Committee consists of Ernesto Marcos, Robert L.
Mitchell and Patricia M. Wallington. Dr. Marcos and Ms. Wallington currently
serve as directors and Mr. Mitchell, a former director of the Company, was
re-elected to the Board for the specific purpose of serving on the Special
Committee. The members of the Special Committee are not and have not been
employees or officers of the Corporation or employees, officers or directors of
PetroFina and its affiliates. The Special Committee expects to retain
independent legal counsel and independent investment advisors to assist the
members of the Special Committee in carrying out their duties and
responsibilities.
 
     As of March 6, 1997, the Company has not responded to the PetroFina merger
proposal and will not do so until the Special Committee completes its review and
evaluation. It is anticipated that the review and evaluation process will be
completed in the next 60 days.
 
     The Company is aware of two shareholder suits filed in Delaware challenging
the proposed merger. See Item 3 of this Form 10-K Annual Report.
 
     FINA, Inc. is engaged, through its wholly-owned, main operating subsidiary,
Fina Oil and Chemical Company ("FOCC"), in crude oil and natural gas exploration
and production; petroleum products refining, supply and transportation and
marketing; and chemicals manufacturing and marketing. A wholly-owned subsidiary
of the Company, Fina Natural Gas Company, is engaged in natural gas marketing.
Fina Technology, Inc., a subsidiary of the Company, licenses certain proprietary
processes to others.
 
     Capital expenditures for 1996 were $263.3 million, or 21% above the prior
year's $218.4 million. Capital expenditures by segments of the Company are shown
in Note 14 to the Consolidated Financial Statements on pages 31 and 32.
Expenditures associated with refining, supply and transportation and marketing
were $72.2 million of the total capital expenditures primarily for efficiency
and yield improvement projects at both refineries and a marketing investment.
Expenditures of $125.3 million for exploration and production were attributable
primarily to exploration and development drilling activity. Expenditures
relating to chemicals were $54.3 million due to major expansions in two of the
Company's four product lines. The capital expenditures budget for 1997 is $261.6
million.
 
                                        1
<PAGE>   4
 
     No major individual assets or subsidiaries were acquired or disposed of
during the five years ending December 31, 1996.
 
     (b) Segment data is shown in Note 14 "Segment Data" to Consolidated
Financial Statements on pages 31 and 32.
 
     (c) The Company has grouped its businesses into (1) crude oil and natural
gas exploration and production, and natural gas marketing; (2) petroleum
products refining, supply and transportation and marketing; and (3) chemicals
manufacturing and marketing, primarily petrochemicals and plastics including
polypropylene, styrene monomer, polystyrene and high density polyethylene, and
the licensing of certain chemical processes. The energy products are produced by
FOCC, a Delaware corporation. Petrochemicals and plastics are manufactured by
FOCC and by Cos-Mar Company ("Cos-Mar"), a 50% owned joint venture.
 
     The Company markets gasoline and other refined products, including naphtha,
jet fuel, distillates, diesel fuel, heavy oils and asphalt, under the FINA(R)
brand or as unbranded products. FINA(R) transportation fuel products are
primarily sold through 2578 branded retail outlets, of which 38 are
company-owned service stations and the remainder are owned and operated by 225
independent businesses located in 13 states in the Southeastern and Southwestern
regions of the United States. The Company also markets petrochemicals and
plastics under the FINA(R) brand. Fina Natural Gas Company is engaged in natural
gas marketing.
 
     Following are products which accounted for more than 10% of consolidated
revenues in 1996, 1995 and 1994, and their appropriate percentage of revenues
for the three years:

</TABLE>
 
     Additional segment data is shown in Note 14 "Segment Data" to Consolidated
Financial Statements on pages 31 and 32 herein.
 
     Sufficient raw material is available in the foreseeable future for
supplying the needs of the various manufacturing units of the Company, although
political situations in the important oil producing nations can aggravate the
supply situation in the United States where imports of oil are necessary to meet
demand.
 
     The Company licenses its patented chemical processes throughout the world.
The net earnings derived from licensing were not material to the consolidated
results of operations in 1996, 1995 and 1994.
 
     The business of the Company cannot be considered seasonal and is sensitive
to crude oil and natural gas pricing, margins between crude oil and refined
products and chemicals margins. There are, however, fluctuations, such as
increased demand for gasoline during summer months. Inflation increases the
costs of labor and supplies and increases costs of acquiring and replacing
property, plant and equipment.
 
     Inventories of refined products and crude oil vary according to the overall
supply environment and in anticipation of price increases or decreases. Payments
for crude oil are generally expected by the 20th day of the month following the
month in which the crude oil was delivered. Payments for refined products are
generally expected within 10 days of billing. Payments for chemicals are
generally expected within 30 days of billing. Credit is sometimes extended for a
longer period on products when there is a surplus, and in some cases, credit
terms are influenced by credit history and financial stability.
 
     No material part of the business is dependent on a single customer or a few
customers. Most of the Company's customers are located in the Southern and
Midwestern regions of the United States, except with respect to chemicals where
customers are located throughout the United States. No single customer accounted
for more than 5% of the Company's sales in 1996, 1995 or 1994, and no account
receivable from any customer exceeded 5% of the Company's consolidated
stockholders' equity at December 31, 1996, 1995 or 1994.
 
                                        2
<PAGE>   5
 
     No material portion of the business is subject to renegotiation of profits
or termination of contracts or subcontracts at the election of the government.
 
     In both the crude oil and natural gas exploration and production and
natural gas marketing segment and the petroleum products refining, supply and
transportation and marketing segment, the principal methods of competition are
price and availability of product. In the petroleum products and chemicals
segments, quality of the product is also a competitive factor.
 
     During 1996, $13.5 million was expended on pollution control and
environmental protection capital projects. It is estimated that environmental
capital expenditures will be approximately $12.6 million companywide in 1997.
Additionally, during 1996, $43.6 million was charged to expense relating to
ongoing environmental administration and maintenance activities at operating
facilities.
 
     The number of persons employed on December 31, 1996 was 2,615 full time and
49 part time.
 
     (d) Sales, operating profit (loss), and identifiable assets for the three
years ended December 31, 1996 were substantially all attributable to domestic
operations.
 
     (e) "Executive Officers of the Registrant" are described in Part III, Item
10.
 
ITEM 2  PROPERTIES
 
     (a) The Company owns and operates two refineries in Texas. The total raw
materials processed at both refineries averaged 211,000 barrels per day for

     At all times the Company has contractual obligations to deliver natural
gas, usually on an "as needed" basis. Therefore, contract quantities are not
fixed and determinable. In May of 1989, the Company began purchasing gas
produced by unaffiliated companies for resale to the Company's customers. During
1996, 182,843 MMCF of gas was purchased and resold from both affiliated and
unaffiliated companies. The Company's obligations to deliver natural gas have
been met.
 
     On December 31, 1996, the Company was obligated to deliver 6,596,284
barrels of crude oil in January 1997, 2,343,561 barrels in February, 2,745,858
barrels in March and 1,759,355 barrels in April. The Company purchases crude oil
either at the lease, on the spot market or on the futures market to fulfill its
commitments. The Company met its contractual obligations to date.
 
ITEM 3  LEGAL PROCEEDINGS
 
     As of December 31, 1996, neither FINA, Inc. nor any of its subsidiaries was
a party to, nor was any of their property subject to, any uninsured material
pending legal proceedings or claim which exceeds 10% of the current assets.
 
     The Company understands that following the public announcement of the
merger proposal of PetroFina described in Item 1 of this Form 10-K Annual
Report, Alan R. Kahn and Kranie Stern, allegedly stockholders of the Company,
each filed suit in the Court of Chancery of the State of Delaware against
PetroFina, FINA and its directors at the date of filing. The suits, which
purport to be class actions, allege a breach of fiduciary duties and seek to
enjoin the merger or, if consummated, to set it aside. The Company will file an
answer to each of the suits denying the allegations and intends to contest the
litigation vigorously.
 
     Management believes that there is no environmental liability pertaining to
proceedings involving a governmental authority with sanctions in excess of
$100,000 which is reasonably foreseeable in relation to its business activities
and operational permits other than:
 
     1. On March 10, 1993, the United States of America ("USA"), on behalf of
        the Secretary of the Army and the Army Corps of Engineers ("Corps"),
        filed a lawsuit seeking injunctive relief requiring FOCC and others to
        restore and revegetate 37.5 acres of seagrass allegedly damaged during
        drilling. On December 16, 1993, the USA, at the request of the Corps,
        filed a second lawsuit seeking an injunction requiring FOCC to remove an
        oil wellhead and its associated structures from the Laguna Madre. A
        settlement has been reached assessing penalties against FOCC of $1.4
        million, and FOCC will assume responsibility for necessary seagrass
        remediation with substantial contribution from other parties.
 
     2. The Florida Department of Environmental Protection has conducted
        audits of three locations in Florida as part of an investigation into
        the repayment of disallowed credits. In two instances, final audit
        reports were issued with requests for repayment totaling $557,265. An
        initial report in the remaining audit has been issued requesting a
        refund of approximately $203,082. FOCC has filed requests for extension
        of time within which to file request for formal administrative
        proceedings.
 
     Environmental contingencies and the Company's policy regarding
environmental costs are discussed in Note 13 to the Consolidated Financial
Statements, on pages 29 and 30. A reserve has been established in accordance
with the policy. The level of future expenditures for environmental matters,
including clean-up obligations, is impossible to determine with any degree of
accuracy.
 
ITEM 4  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
     There were no matters submitted to a vote of security holders during the
fourth quarter of the Company's fiscal year ended December 31, 1996.

ITEM 7  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
DISCUSSION OF FINANCIAL INFORMATION
 
     Net income for 1996 was $153 million compared to $104 million in 1995 and
$102 million in 1994. Net income for 1995 was $143 million prior to an
accounting change for Statement of Financial Accounting Standards No. 121 ("SFAS
121") resulting in a $38 million reduction to net income.
 
     Earnings per common share in 1996 were $4.91. Earnings per common share in
1995, after SFAS 121, were $3.35 compared to $3.27 in 1994. Stockholders' equity
was $1.2 billion or $39.96 per common share, in 1996 compared to $1.2 billion,
or $37.75 per common share, in 1995 and $1.1 billion, or $36.70 per common
share, in 1994. The increase in stockholders' equity in 1996, 1995 and 1994 was
attributable to net income less annual dividends of $2.70 per share in 1996,
$2.30 per share in 1995 and $1.80 per share in 1994.
 
     Sales and other operating revenues for 1996 were $4.1 billion compared to
$3.6 billion in 1995 and $3.4 billion in 1994. The increase in 1996 was
primarily due to higher crude oil and natural gas prices, higher refined product
prices and higher chemical volumes.
 
                                        7
<PAGE>   10
 
     Total assets in 1996 were $2.9 billion. Total assets in 1995 and 1994 were
$2.5 billion. The increase in 1996 was principally due to capital expenditures
exceeding depreciation, depletion and amortization, additional investments in
affiliates, and an increase in receivables.
 
     Cost of raw materials and products purchased increased 16% in 1996
primarily due to higher crude oil and natural gas prices and higher chemical
volumes. Direct operating expenses as a percent of sales and other operating
revenues were relatively constant for 1996, 1995 and 1994.
 
     Selling, general and administrative expenses were $87.0 million, $86.2
million and $78.1 million in 1996, 1995 and 1994, respectively.
 
     Interest expense decreased in 1996 from 1995 and 1994 because of lower
interest rates, refinancing activities and lower average debt outstanding.
 
     Interest and other income for 1996 is a loss of $2.7 million compared to an
$11.1 million loss in 1995 and a $16.0 million gain in 1994. For 1995 and 1994,
the gain or the loss was primarily associated with asset sales of exploration
and production properties.
 
     Long-term balance sheet obligations less current installments were $587
million at year-end 1996, compared to $498 million at year-end 1995 and $532
million at the end of 1994. Total balance sheet debt was $696 million at
year-end 1996 compared to $554 million at year-end 1995 and $650 million at
year-end 1994. The increase in 1996 was primarily due to the termination of $120
million of off-balance-sheet financing which consisted of an $80 million
accounts receivable sale and a $40 million guaranteed Cos-Mar joint venture
borrowing from a bank which was replaced with an additional investment by the
Company.
 
     During the fourth quarter of 1995, the Company adopted SFAS 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed of", ("SFAS 121") which resulted in a before-tax addition of
$58,723,000 to depreciation, depletion and amortization expense. After tax, the
additional charge was $38,173,000 or $1.22 per share. Under SFAS 121, the
Company now evaluates impairment of exploration and production assets on a
field-by-field basis rather than using a one country cost center for its proved
properties. On this basis, certain fields are impaired because they are not
expected to recover their entire book value from future cash flows. The value of
certain marketing assets in the Company's Downstream business were also impaired
under SFAS 121. As a result, the Company recognized a non-cash, pre-tax charge
of $52,523,000 related to its exploration and production assets and $6,200,000
related to its marketing assets. The fair values of the impaired assets were
determined by using the present value of expected future cash flows for the oil
and gas properties and sales prices for similar assets for marketing assets. If
estimated future cash flows are not achieved with respect to certain fields,
further writedowns may be required.
 
     Crude oil, refined products and chemical inventories are priced at the
lower of cost (last-in, first-out, "LIFO") or market on an aggregate basis.
Materials and supplies are priced at average cost, not in excess of market; in
the case of material salvaged, an allowance is made for obsolescence. The excess
of replacement cost of crude oil and refined products and chemicals over LIFO
cost at December 31, 1996 was approximately $65.8 million and $7.4 million at
December 31, 1995.
 
     The impact of the various lines of business on the financial position and
results of operations is discussed in the following text under appropriate
operating unit subheadings.
 
  Exploration and Production and Natural Gas Marketing
 
     Revenues and earnings (loss) before interest and income tax were $569.0
million and $69.3 million, $352.9 million and ($66.9 million), and $549.2
million and ($3.4 million) for 1996, 1995 and 1994, respectively. Increased net
earnings in 1996 were due to higher crude oil and natural gas prices, higher
production volumes, lower lifting costs, higher natural gas marketing earnings
and the effect of the SFAS 121 charge of $52.5 taken in 1995.
 
     Average crude oil, condensate and natural gas liquids production was 3.8
net million barrels in 1996, an increase from 3.7 net million barrels in 1995.
Natural gas production in 1996 was 56.7 billion cubic feet and 52.1 billion
cubic feet in 1995.
 
                                        8
<PAGE>   11
 
     Average wellhead prices for crude rose $3.80 per barrel to $19.33 in 1996.
Average wellhead prices for natural gas were $2.45 per MCF in 1996, up from
$1.57 per MCF in 1995.
 
     Increased drilling activity resulted in record reserve additions of 26.1
million barrels of oil equivalent. Finding and development costs in 1996 were
$5.71 per barrel oil equivalent, compared to $6.03 in 1995. Lifting costs, at
$4.21 per barrel oil equivalent, were improved from $4.35 in 1995.
 
     The Company participated in 29 gross exploratory wells, compared to 17 in
1995 and 8 in 1994. The success rate was 72% compared to 71% in 1995 and 50% in
1994. The Company's participation in net exploratory wells was 23.9, compared
with 11.8 in 1995 and 2.7 in 1994. The success rate for net exploratory wells
was 75% compared to 73% in 1995 and 56% in 1994.
 
     Natural Gas Marketing sales volumes of 500 million cubic feet per day in
1996 increased from 494 million cubic feet per day in 1995.
 
  Refining, Supply and Transportation and Marketing
 
     Revenues and earnings (loss) before interest and income tax were $2.5
billion and ($16.8 million), $2.2 billion and ($4.7 million) and $2.0 billion
and $47.2 million for 1996, 1995 and 1994, respectively.
 
     Lower results during 1996 were primarily due to lower industry fuels and
aromatics margins and increased turnaround activity at both refineries. These
factors were partially offset by improved yields and plant operations.
 
     1996 was the fifth consecutive year of low Gulf Coast industry margins
primarily due to increased supplies attributed to debottlenecking of industry
upgrading capacity and increased imports. Lower aromatics margins generally
reflected increased supplies from reducing aromatics in gasoline and increased
extraction capacity.
 
     Refinery operations in 1996 included a throughput of 211,000 barrels per
day. Throughput was limited by scheduled major turnarounds at the Port Arthur,
Texas Refinery and in the Big Spring, Texas Refinery which occurs only once
every four years, and by product pipeline constraints. At the Big Spring, Texas
Refinery, a major Fluid Catalytic Cracking Unit enhancement improved yields of
higher value products, but the financial benefits were generally offset by the
planned turnaround.
 
  Chemicals
 
     Revenues and earnings before interest and income taxes were $1.0 billion
and $231.2 million, $1.1 billion and $290.6 million and $890.3 million and
$164.4 million for 1996, 1995 and 1994, respectively.
 
     Chemicals was the largest contributor to earnings, although down 20.4% from
1995 due to a 40% drop in industry margins reflecting new capacity additions
only partially offset by higher volumes. Record production was achieved at all
sites; styrene was up 10%, polystyrene up 27%, polypropylene up 37% and
polyethylene up 9%.
 
     Total chemical sales volumes were up 25% versus the prior year reflecting
the higher production levels and major expansion projects at the polypropylene
and polystyrene plants.
 
     In mid-June, a 250 million pound per year crystal polystyrene production
line was completed, making the Carville, Louisiana Polystyrene Plant the largest
polystyrene plant in the world. At the Polypropylene Plant in LaPorte, Texas, a
500 million pound-per-year expansion started up at the end of 1995, making it
the largest polypropylene plant in the world, and it operated in a sold-out
position throughout the year. Capacity was doubled at the joint venture
Propylene Splitter Plant near Houston. Project implementation began on an
expansion of the High Density Polyethylene Plant near Houston that will double
the facility's production capacity when completed in mid-1998. Engineering also
began on another expansion at the Polypropylene Plant which could further
increase capacity by 550 million pounds in late 1998.

ENVIRONMENTAL MATTERS
 
     The Company was contingently liable at December 31, 1996, under pending
lawsuits and other claims, some of which involved substantial sums. Considering
certain liabilities or reserves that have been set up for the lawsuits and
claims, and the difficulty in determining the ultimate liability in some of
these matters, internal counsel is of the opinion that the amounts, if any, that
ultimately might be due in connection with such lawsuits and claims would not
have a material adverse effect upon the Company's consolidated financial
condition.
 
     The Company is subject to loss contingencies pursuant to federal, state and
local environmental laws and regulations. These regulations, which are currently
changing, regulate the discharge of materials into the environment and may
require the Company to incur future obligations to investigate the effects of
the release or disposal of certain petroleum, chemical and mineral substances at
various sites; to remediate or restore these sites; to compensate others for
damage to property and natural resources and for remediation and restoration
costs. These possible obligations relate to sites owned by the Company or others
and associated with past or present operations, including sites at which the
Company has been identified as a Potentially Responsible Party ("PRP") under the
federal Superfund laws and comparable state laws. The Company is currently
participating in environmental investigations, assessments and cleanups under
these regulations at federal Superfund and state-managed sites, as well as other
cleanup sites, including operating and closed refineries, chemical facilities,
service stations, pipelines and terminals. The Company may in the future be
involved in additional environmental investigations, assessments and cleanups.
The magnitude of future costs will depend on factors such as the unknown nature
of contamination at many sites, the unknown timing, extent and method of the
remedial actions which may be required and the determination of the Company's
liability in proportion to other responsible parties.
 
     Environmental expenditures are expensed or capitalized depending on their
future economic benefit. Expenditures that relate to an existing condition
caused by past operations and that have no future economic benefit are expensed.
Liabilities for expenditures of a noncapital nature are recorded when
environmental assessment and/or remediation is probable, and the costs can be
reasonably estimated. The Company has accrued for environmental remediation
obligations of $20,339,000 and $20,856,000 at December 31, 1996 and 1995,
respectively. Substantially all amounts accrued are expected to be paid out over
the next five to six years. The level of future expenditures for environmental
remediation obligations is impossible to determine with any degree of
reliability. The Company spent approximately $13,484,000 and $14,782,000 at
December 31, 1996 and 1995, respectively, in capital expenditures for
environmental protection and for compliance with federal, state and local
environmental laws and regulations. In addition, the Company expensed
$43,621,000 and $43,135,000 in 1996 and 1995, respectively, for ongoing
environmental administration and maintenance activities at operating facilities.
The Company also paid $10,165,000 for Superfund taxes in 1995. Total
environmental cash expenditures are expected to increase over an extended period
of time. Estimated environmental capital expenditures for 1997 are $12,598,000.
 
CAPITAL RESOURCES AND LIQUIDITY
 
     The Company's cash liquidity requirements for working capital, capital
expenditures, acquisitions and debt interest over the past three years were
financed primarily by a combination of funds generated from operations,
borrowings and dispositions of assets.
 
     Operating cash flows, defined as earnings before interest, taxes,
depreciation, depletion, amortization and lease impairment (EBITDA), was $437.5
million in 1996 compared to $417.9 million in 1995 and $382.9 million in 1996.
The increase in 1996 operating cash flows compared to 1994 and 1995 are the
result of increased operating profits by the Company due to improved Chemical
profits in 1995 and higher Upstream profits in 1996.
 
     During 1996, cash provided by operating activities totaled $221.6 million,
compared with $366.2 million in 1995 and $275.4 million in 1994. Cash flow from
operating activities during 1995 increased $90.2 million compared to the prior
year primarily resulting from a $46.5 million reduction of working capital and a
$40.6 million improvement to earnings prior to the non-cash impact of SFAS 121.
Cash flow from operating
 
                                       10
<PAGE>   13
 
activities during 1996 decreased $144.6 million compared to 1995 primarily due
to the termination of the $80 million account receivable sale and a $10.4
million increase in working capital in 1996 compared to the $46.5 million
decrease in working capital in 1995.
 
     The Company's year-end 1996 balance sheet debt was $696 million compared to
$554 million at year-end 1995 and $650 million at year-end 1994. The increase in
debt during 1996 was primarily due to the termination of the $120 million of
off-balance-sheet financing. During 1995, debt was reduced primarily with
proceeds from the sale of assets and funds from operations. The majority
stockholder of the Company has not been the principal lender in the past three
years.
 
     In July 1996, the Company offered initial public debt of $125 million
five-year notes at market rates. The proceeds were used to refinance debt at
lower costs. The public debt was registered with the Securities and Exchange
Commission on Form S-3 in June 1996 and carried credit ratings of single A from
Standard & Poor's and A-3 from Moody's Investors Service.
 
     The Company replaced its short term bank borrowings with a $400 million
commercial paper program supported fully by its unused revolving credit facility
in the third quarter of 1996.
 
     In 1993, the Company entered into long-term note agreements with certain
insurance companies that provided for unsecured borrowings aggregating $275
million under Series A, Series B, and Series C Senior Notes. Proceeds from these
notes were used to repay other debt.
 
     The Company has an unsecured revolving credit facility with a group of
banks in the amount of $425 million. Under the facility, the Company has
available credit in an amount of $325 million through February 2002.
 
     The Company paid dividends of $2.70 per share in 1996, $2.30 per share in
1995 and $1.80 per share in 1994.
 
     The Company believes that cash provided by operations, together with
borrowings available under the revolving credit facility with banks, will be
sufficient to fund the Company's working capital requirements, capital
expenditures, principal, interest and dividends.

     1996 capital expenditures were 21% above 1995. The projected capital
expenditures budget in 1997 is $262 million.
 
IMPACT OF INFLATION AND CHANGING PRICES
 
     The business of the Company is not seasonal but is sensitive to crude oil
and natural gas pricing, margins between crude oil and refined products and
chemical margins. Inflation impacts the Company by increasing costs of labor and
supplies, and increasing costs of acquiring and replacing property, plant and
equipment. The replacement cost of property, plant and equipment is generally
greater than the historical cost as a result of inflation.
 
     Market conditions continue to be the primary factor in determining the
prices and costs of Company products.

MANAGEMENT RESPONSIBILITY FOR CONSOLIDATED FINANCIAL STATEMENTS
 
     The management of FINA, Inc. is responsible for the financial information
and representations contained in the Consolidated Financial Statements and other
sections of this Annual Report on Form 10-K. The Company believes that the
financial statements fairly reflect the substance of its transactions and
present its consolidated financial position and results of operations in
conformity with generally accepted accounting principles. In preparing the
Consolidated Financial Statements, the Company is required to include amounts
that are based on estimates and judgments which the Company believes are
reasonable under the circumstances.
 
     The Company has developed and maintains a system of internal accounting
controls designed to provide reasonable assurance that assets are safeguarded
from loss or unauthorized use and that transactions are properly recorded. In
establishing and maintaining internal controls, management must exercise
judgment in determining that the cost of such controls does not exceed the
benefits to be derived.
 
     The Board of Directors exercises its oversight role for the Consolidated
Financial Statements through its Audit Committee, which is composed solely of
directors who are not officers or employees of the Company. The Audit Committee
meets with Company management, internal auditors and the independent auditors to
review the audit scope and any recommendations for improvements in the Company's
internal accounting controls. The independent auditors are engaged to provide an
objective, independent view of the fairness of reported operating results and
financial condition.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders
FINA, Inc.:
 
     We have audited the consolidated financial statements of FINA, Inc. and
subsidiaries as listed in the accompanying index. In connection with our audits
of the consolidated financial statements, we also have audited the consolidated
financial statement schedule as listed in the accompanying index. These
consolidated financial statements and financial statement schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements and financial statement
schedule based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of FINA, Inc.
and subsidiaries as of December 31, 1996 and 1995, and the results of their
operations and their cash flows for each of the years in the three-year period
ended December 31, 1996, in conformity with generally accepted accounting
principles. Also, in our opinion, the related consolidated financial statement
schedule, when considered in relation to the basic consolidated financial
statements taken as a whole, presents fairly, in all material respects, the
information set forth therein.
 
     As discussed in note 6 to the consolidated financial statements, the
Company adopted the provisions of the Financial Accounting Standards Board's
Statement of Financial Accounting Standards No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of" in
1995.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1996
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
(A) GENERAL
 
     FINA, Inc. with subsidiaries ("the Company") is an integrated energy
company. The Company's principal lines of business are crude oil and natural gas
exploration and production and natural gas marketing ("Upstream"); petroleum
products refining, supply and transportation and marketing ("Downstream"); and
chemicals manufacturing and marketing ("Chemicals"). The principal markets for
refined products are domestic wholesale and retail markets while natural gas is
sold primarily to domestic marketers and local distribution companies.
Petrochemical and plastic products are primarily sold to domestic manufacturers
of fiber, film, packaging and consumable products. Raw materials are readily
available and the Company is not dependant upon a single supplier or a few
suppliers.
 
     Class A and Class B common stock are identical in all respects except on
any vote for the election of directors. The holders of record of the Class B
Common Stock are entitled to elect the smallest number comprising more than half
of the directors to be elected and the remaining directors are elected by the
holders of record of the Class A Common Stock voting separately as a class.
Petrofina Delaware, Incorporated ("PDI") owns 100% of the Class B common stock
and approximately 85% of the Class A common stock. PetroFina S.A. ("PetroFina"),
a Belgian publicly-held corporation, owns 100% of American Petrofina Holding
Company which owns 100% of the stock of PDI.
 
     On February 25, 1997, the Company received a letter from PetroFina
proposing a merger transaction in which the Company would become a wholly-owned
affiliate of PetroFina. The transaction would be a negotiated merger in which
each holder of a Class A share not owned by PetroFina and its affiliates would
receive the equivalent of $60 U.S. per share in cash, PetroFina shares or a
combination of cash and PetroFina shares. PetroFina advised that it intends to
seek listing on The New York Stock Exchange of American Depositary Receipts
representing shares of PetroFina concurrently with the transaction. Consummation
of the merger would be subject, among other things, to approval of the Board of
Directors of the Company and the negotiation and execution of a definitive
merger agreement containing customary terms and conditions.
 
(B) PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of the Company
and all of its significant subsidiaries. All significant intercompany balances
and transactions have been eliminated in consolidation.
 
(C) STATEMENTS OF CASH FLOWS
 
     For purposes of reporting cash flows, all certificates of deposit and short
term highly liquid debt instruments, such as U.S. Treasury bills and notes, with
original maturities of three months or less are considered cash equivalents.
 
     The indirect method is used to present cash flows from operating
activities. Additional cash flow information follows:

                          FINA, INC. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Capital lease obligations of $27,548,000 in 1994 were converted into debt
as a result of termination of time charters relating to tankers.
 
(D) INVESTMENTS IN AFFILIATES
 
     Investments in affiliates in which the Company owns between 20% and 50% of
the voting stock are carried at amortized cost adjusted for changes in equity
since acquisition.
 
(E) INVENTORIES
 
     Crude oil and refined products and chemicals are priced at the lower of
cost (last-in, first-out) ("LIFO") or market on an aggregate basis. Materials
and supplies are priced at average cost, not in excess of market, less an
allowance for obsolescence. The excess of replacement cost of crude oil and
refined products and chemicals over LIFO cost was $65,846,000 at December 31,
1996 and $7,356,000 at December 31, 1995.
 
     Certain inventory quantities were reduced, resulting in liquidations of
LIFO inventory which decreased pretax earnings by approximately $4,400,000 in
1995.
 
     A summary of inventories follows:

(F) PROPERTY, PLANT AND EQUIPMENT
 
     Oil and gas properties are accounted for in accordance with Statement of
Financial Accounting Standards ("SFAS") No. 19. Costs to acquire mineral
interests in oil and gas properties, to drill exploratory wells that find proved
reserves and to drill and equip development wells are capitalized. Geological
and geophysical costs and costs to drill exploratory wells that do not find
proved reserves are expensed.
 
     Unproved oil and gas properties that are individually significant are
periodically assessed for impairment of value and, if necessary, a loss is
recognized by providing an impairment allowance. The remaining unproved oil and
gas properties are aggregated and an overall impairment allowance is provided
based on prior experience. Capitalized costs of proved oil and gas properties
are depreciated and depleted by the unit-of-production method based on proved
oil and gas reserves estimated by Company engineers.
 
     Substantially all other property, plant and equipment is depreciated by the
straight-line method at rates based on the estimated useful lives of the classes
of property.
 
     Interest is capitalized as a component of the cost of construction and
development projects in progress.
 
     Repairs and maintenance are charged to earnings as incurred. Renewals and
betterments are capitalized. When assets are sold, retired or otherwise disposed
of, the applicable costs and reserves are removed from the accounts and the
resulting gain or loss is recognized.

(H) INCOME TAXES
 
     Income taxes are accounted for pursuant to SFAS 109 "Accounting for Income
Taxes." The Company files a consolidated Federal income tax return with PDI and
its affiliates. Under the terms of the tax sharing agreement with PDI, the
Company is allocated Federal income taxes on a separate return basis.
 
(I) EARNINGS PER COMMON SHARE
 
     Earnings per common share is based on the weighted average number of
outstanding shares. Shares issuable upon the exercise of stock options are
excluded from the computation since their effect is insignificant.
 
(J) FINANCIAL INSTRUMENTS
 
     The Company utilizes derivative financial instruments to manage market
risks and reduce its exposure resulting from fluctuations in interest rates and
the prices of crude oil, refined products and natural gas. Derivative
instruments used include swap agreements, futures and options contracts and
forward purchase commitments. Gains and losses related to qualifying hedges are
deferred and included in the measurement of the related transaction, when the
hedged transaction occurs. Realized and unrealized changes in the fair value of
the remaining derivative financial instruments and forward commitments are
recognized in income in the period in which the change occurs. The Company's
practice is to not hold or issue financial instruments for trading purposes.
 
     Instruments are either exchange-traded or with counterparties of high
credit quality; therefore, the risk of nonperformance by the counterparties is
considered to be negligible. Additional information regarding financial
instruments is shown in Note 4.
 
(K) USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

     The Company has a $400,000,000 revolving bank credit facility through May
2000 of which none was outstanding under the facility at December 31, 1996. The
Company intends to use borrowings under this facility to finance the repayment
of $200,000,000 of commercial paper, classified as long term debt at December
31, 1996. Borrowings under the credit facility bear interest at various market
rate options. This facility was subsequently replaced on February 27, 1997 with
an amended facility with similar terms.
 
     The Senior Notes and the bank revolving credit facility contain provisions
that limit mergers and sales of assets, limit the incurrence of indebtedness and
restrict payments to stockholders. No material amounts of current and long term
debt are collateralized by Company assets.
 
     Letters of credit are maintained with various banks, aggregating
$70,660,000 at December 31, 1996; principally for pollution control, workers'
compensation obligations and Department of Energy crude acquisition.
 
     The aggregate maturities of long term debt and capitalized lease
obligations for the five years ending December 31, 2001 are as follows:
1997 -- $37,188,000; 1998 -- $63,362,000; 1999 -- $54,225,000; 2000 --
$48,467,000; and 2001 -- $148,736,000.
 
(4) FINANCIAL INSTRUMENTS AND FAIR VALUES
 
     The Company uses swap agreements, futures and options contracts and forward
purchase commitments to reduce its exposure to fluctuations in interest rates
and in the prices of crude oil, refined products and natural gas.

                          FINA, INC. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Interest rate swap agreements are used to help manage interest rate
exposure. Amounts to be paid or received under interest rate swap agreements are
accrued as interest rates change and are recognized over the life of the swap
agreements as an adjustment to interest expense. The related amounts payable to,
or receivable from, the counterparties are included in other accrued
liabilities. The fair value of the swap agreements was not recognized in the
consolidated financial statements since they are accounted for as hedges. These
swap agreements expire at various dates through 2003 and effectively convert an
aggregate principal amount of $227,453,000 of fixed rate, long term debt into
variable rate borrowings and $50,000,000 of variable rate borrowings to fixed at
December 31, 1996. The variable interest rates are based on 3 month and 6 month
LIBOR rates. At December 31, 1996 and 1995, the weighted average variable
interest rates under these agreements were 5.6% and 5.9%, respectively, and
fixed rates were 6.2% and 6.5%, respectively.
 
     The estimated fair value of the interest rate swap agreements, based on
current market rates, approximated a net receivable of $4,543,000 and a net
payable of $815,000 at December 31, 1996 and 1995, respectively. Exposure to
credit loss could occur when the fair value of the agreements is a net
receivable. The outstanding borrowings due under the commercial paper program,
to PDI and to various banks bear interest at current market rates and thus, the
carrying amount of debt approximates estimated fair value. The estimated fair
value of the debt instruments that bear interest at fixed rates was $408,743,000
($423,680,000 carrying value) at December 31, 1996, and $331,000,000
($320,000,000 carrying value) at December 31, 1995.
 
     The Company hedges crude oil, refined products and natural gas future
purchases and sales commitments. The Company also uses derivative financial
instruments to reduce financial exposure from price changes related to
anticipated crude oil purchases and refined product and natural gas sales. At
December 31, 1996, the Company had futures contracts to purchase crude oil and
refined products in the amount of $3,763,000 and forward contracts to purchase
crude oil and refined products of $87,197,000. At December 31, 1995, the Company
had futures contracts to sell crude oil and refined products in the amount of
$13,661,000 and forward contracts to purchase crude oil and refined products of
$46,323,000. The estimated fair value and carrying value of these outstanding
contracts was a net receivable of $4,295,000 and $62,000 at December 31, 1996
and 1995, respectively. Crude and refined product futures and forwards contracts
are used to facilitate the supply of crude to the Company's refineries and sales
of refined products while attempting to minimize price risk. The Company
recognizes realized and unrealized gains and losses on these contracts in income
in the period in which the change occurs.
 
     The Company also had futures contracts to sell natural gas as a hedge of
equity production in the amount of $19,388,000 at December 31, 1996. The
estimated fair value and carrying value of these outstanding contracts was a net
receivable of $1,939,000 at December 31, 1996. Gains and losses on these
qualifying hedges are deferred and included in the measurement of the related
transaction, when the hedged transaction occurs. Derivative financial
instruments related to natural gas activities were not significant at December
31, 1995.
 
     The estimated fair values of the futures and forward contracts are based on
quoted market prices and generally have maturities of one year or less.
 
     Market value is not readily determinable for certain equity investments and
long term receivables with a carrying value of $105,290,000 and $36,572,000 at
December 31, 1996 and 1995, respectively. The reported amounts of cash
equivalents, short term receivables and payables and short term debt approximate
fair value due to their short maturities.

(6) IMPAIRMENT OF LONG-LIVED ASSETS
 
     During the fourth quarter of 1995, the Company adopted SFAS 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of" which resulted in a before-tax addition of $58,723,000 to
depreciation, depletion and amortization expense. After tax, the additional
charge was $38,173,000 or $1.22 per share.

                          FINA, INC. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Under SFAS 121, the Company now evaluates impairment of exploration and
production assets on a field-by-field basis rather than using a one country cost
center for its proved properties. On this basis, certain fields are impaired
because they are not expected to recover their entire carrying value from future
cash flows. In addition to the change in grouping of proved properties, the
value of certain marketing assets in the Company's Downstream business were also
determined to be impaired under SFAS 121. As a result, the Company recognized a
non-cash pre-tax charge of $52,523,000 related to its Upstream exploration and
production assets and $6,200,000 related to its Downstream marketing assets. The
fair values of the impaired assets were determined by using the present value of
expected future cash flows for the oil and gas properties and sales prices for
similar assets for certain marketing assets. If estimated future cash flows are
not achieved with respect to certain fields, further writedowns may be required.
 
(7) EMPLOYEE STOCK OPTIONS
 
     Options to purchase shares of Class A Common Stock have been granted to
officers and employees under a stock option plan adopted in 1979. The stock
option plan expired in 1989, and no further grants will be made under that plan.

(9) EMPLOYEE AND POST RETIREMENT BENEFITS
 
     The Company and its subsidiaries have two defined benefit pension plans
covering substantially all employees. The benefits are based on years of service
and the employee's final average monthly compensation. The Company's funding
policy is to contribute annually not less than the minimum required nor more
than the maximum amount that can be deducted for Federal income tax purposes.
Contributions are intended to provide not only for benefits attributed to
service to date but also for those expected to be earned in the future.
 
     A restoration benefit plan provides supplemental pension benefits to
certain participants whose benefits are limited by the defined benefit pension
plans. The funding policy is to annually contribute amounts equal to benefit
payments made.
 
     A summary of the plans' funded status and the amounts recognized in the
consolidated balance sheet follows:

     In addition to providing pension benefits, certain health care and life
insurance benefits are provided to active and certain retired employees who meet
eligibility requirements defined in plan documents. The health care benefits in
excess of certain limits and the life insurance benefits are insured. The costs
of providing these benefits for active employees are expensed when the insurance
premiums and claims are paid. The cost of providing these benefits for active
employees was $8,619,000 in 1996, $8,594,000 in 1995 and $10,092,000 in 1994.

     For measurement purposes, a 7.00% and 6.79% weighted average annual rate of
increase in the per capita cost of covered benefits (i.e., health care cost
trend rate) for pre-65 and post-65 years of age, respectively, was assumed for
1997; the rate was assumed to decrease gradually to 6% for pre-65 and 5% for
post-65 years of age by the year 2002 and remain at that level thereafter. A
7.68% and 7.14% annual rate for pre-65 and post-65 years of age, respectively,
was assumed for 1996. The health care cost trend rate assumption has a
significant effect on the amounts reported. For example, increasing the assumed
health care cost trend rates by one percentage point in each year would increase
the accumulated postretirement benefit obligation as of December 31, 1996 by
$3,280,000 and the aggregate of the service and interest cost components of net
periodic postretirement benefit cost for the year ended December 31, 1996 by
$243,000.
 
     The weighted average discount rate used in determining the accumulated
postretirement benefit obligation was 7.75%, 7.5% and 8.75% at December 31,
1996, 1995 and 1994, respectively. The effect on the accumulated benefit
obligation of these changes was an decrease of $1,674,000 in 1996 and an
increase of $7,766,000 in 1995.
 
     Defined contribution retirement savings plans (Thrift Plans) are available
to substantially all employees. The Thrift Plans permit employees to elect
salary deferral contributions of up to 10% of their compensation on a
tax-deferred basis and requires the Company to match up to the first 6% of the
participants' compensation in the highest matched plan subject to salary caps.
The expense for the Company's contribution was $5,965,000 in 1996, $5,911,000 in
1995 and $5,963,000 in 1994.
 
(10) SALE OF ACCOUNTS AND NOTES RECEIVABLE
 
     The Company sold certain accounts and notes receivable with recourse.
Accounts receivable sold with recourse were $80,000,000 at December 31, 1995.
The Company reimbursed the accounts receivable facility with proceeds from its
commercial paper program in 1996. Notes receivable sold with recourse were
$15,562,000 and $27,742,000 at December 31, 1996 and 1995, respectively. The
Company remains obligated to reimburse the purchasers for any uncollectible
amounts pursuant to the recourse provisions of the agreements.
 
(11) LEASES
 
     The Company occupies certain marketing and manufacturing facilities and
uses certain equipment under leases expiring at various dates over the next 20
years. Under terms of certain lease agreements, the Company has agreed not to
mortgage certain of its interests in oil and gas properties.

     Accounts payable include $34,127,000 and $13,410,000 at December 31, 1996
and 1995, respectively, to affiliates.
 
     Interest expense relating to borrowings from PDI (see note 3) was
$5,125,000 in 1996, $12,938,000 in 1995 and $13,916,000 in 1994. Accrued
liabilities include accrued interest of $607,000 at December 31, 1995, payable
to PDI for such borrowings. Crude oil and natural gas aggregating $13,245,000 in
1996, $8,953,000 in 1995 and $16,626,000 in 1994 were purchased from PDI in the
ordinary course of business.
 
     Refined products and chemicals aggregating $57,913,000 in 1996, $53,542,000
in 1995 and $34,963,000 in 1994 were purchased from PetroFina and its affiliates
other than PDI in the ordinary course of business.
 
(13) CONTINGENCIES
 
     The Company was contingently liable at December 31, 1996, under pending
lawsuits and other claims, some of which involved substantial sums. Considering
certain liabilities that have been set up for the lawsuits and claims, and the
difficulty in determining the ultimate liability in some of these matters,
internal counsel is

of the opinion that the amounts, if any, that ultimately may be due in
connection with such lawsuits and claims would not have a material adverse
effect upon the Company's consolidated financial condition.
 
     The Company is subject to loss contingencies pursuant to federal, state and
local environmental laws and regulations. These regulations, which are currently
changing, regulate the discharge of materials into the environment and may
require the Company to incur future obligations to investigate the effects of
the release or disposal of certain petroleum, chemical and mineral substances at
various sites; to remediate or restore these sites; to compensate others for
damage to property and natural resources and for remediation and restoration
costs. These possible obligations relate to sites owned by the Company or others
and associated with past or present operations, including sites at which the
Company has been identified as a potentially responsible party ("PRP") under the
federal Superfund law and comparable state laws. The Company is currently
participating in environmental investigations, assessments and cleanups under
these regulations at federal Superfund and state-managed sites, as well as other
cleanup sites, including operating and closed refineries, chemical facilities,
service stations, pipelines and terminals. The Company may in the future be
involved in additional environmental investigations, assessments and cleanups.
The magnitude of future costs will depend on factors such as the unknown nature
and contamination at many sites, the unknown timing, extent and method of the
remedial actions which may be required and the determination of the Company's
liability in proportion to other responsible parties.
 
     Environmental expenditures are expensed or capitalized depending on their
future economic benefit. Expenditures that relate to an existing condition
caused by past operations and that have no future economic benefit are expensed.
Liabilities for expenditures of a noncapital nature are recorded when
environmental assessment and/or remediation is probable, and the costs can be
reasonably estimated. The Company has accrued for environmental remediation
obligations of $20,339,000 and $20,856,000 at December 31, 1996 and 1995,
respectively. Substantially all amounts accrued are expected to be paid out over
the next five to six years. The level of future expenditures for environmental
remediation obligations is impossible to determine with any degree of
reliability. The Company spent approximately $13,484,000 and $14,782,000 at
December 31, 1996 and 1995, respectively, in capital expenditures for
environmental protection and for compliance with federal, state and local
environmental laws and regulations. In addition, the Company expensed
$43,621,000 and $43,135,000 in 1996 and 1995, respectively, for ongoing
environmental administration and maintenance activities at operating facilities.
The Company also paid $10,165,000 for Superfund taxes in 1995. Total
environmental cash expenditures at the Company's operating locations are
expected to increase over an extended period of time as the Company complies
with present and future regulatory requirements. Estimated environmental capital
expenditures for 1997 are $12,598,000 (unaudited).

(1) During the fourth quarter of 1995, the Company adopted SFAS 121, "Accounting
    for the Impairment of Long Lived Assets and for Long-Lived Assets to be
    Disposed Of". As a result, the Company recognized a before-tax addition of
    $58,723,000 to depreciation, depletion and amortization expense, of which
    $52,523,000 was related to its Upstream business and $6,200,000 was related
    to its Downstream business. After tax, the additional charge was $38,173,000
    or $1.22 per share.
 
     Consolidated totals are after elimination of inter-segment amounts.
Operating profit (loss) is sales less operating expenses and is substantially
all derived from domestic operations. Identifiable assets are those assets that
are used in the operations in each business segment.
 
     Most customers are located in the South and Midwest regions of the United
States. No single customer accounted for more than 5% of sales in 1996, 1995 or
1994, and no account receivable from any customer exceeded 5% of consolidated
stockholders' equity at December 31, 1996, 1995 or 1994.

(2) During the quarter ended December 31, 1995, the Company adopted SFAS 121,
    "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
    Assets to Be Disposed Of" which resulted in a before-tax addition of

(17) SUBSEQUENT EVENTS
 
     On February 25, 1997, the Company received a letter from PetroFina
proposing a merger transaction in which the Company would become a wholly-owned
affiliate of PetroFina. The transaction would be a negotiated merger in which
each holder of a Class A share not owned by PetroFina and its affiliates would
receive the equivalent of $60 U.S. per share in cash, PetroFina shares or a
combination of cash and PetroFina shares. PetroFina advised that it intends to
seek listing on The New York Stock Exchange of American Depositary Receipts
representing shares of PetroFina concurrently with the transaction. Consummation

merger would be subject, among other things, to approval of the Board of
Directors of the Company and the negotiation and execution of a definitive
merger agreement containing customary terms and conditions.
 
     Following receipt of the merger proposal, the Board of Directors of the
Company acting by written consent appointed a special committee of independent
directors (the "Special Committee") to review and evaluate the merger proposal
of PetroFina. The Special Committee expects to retain independent legal counsel
and independent investment advisors to assist the members of the Special
Committee in carrying out their duties and responsibilities.
 
     The Company understands that following the public announcement of the
merger proposal of PetroFina two shareholders of the Company filed suit in the
Court of Chancery of the State of Delaware against PetroFina, the Company and
its directors at the date of filing. The suits, which purport to be class
actions, allege a breach of fiduciary duties and seek to enjoin the merger or,
if consummated, to set it aside. The Company will file an answer to each of the
suits denying the allegations and intends to contest the litigation vigorously.
Management is of the opinion, to the best of their knowledge, that the amounts,
if any, that ultimately may be due in connection with such suits would not have
a material adverse effect upon the Company's consolidated financial condition.

(D) RESERVE QUANTITY INFORMATION
 
     The following table presents the Company's estimate of its proved oil and
gas reserves, all of which are located in the United States. The Company
emphasizes that reserve estimates are inherently imprecise and that estimates of
new discoveries are more imprecise than those of producing oil and gas
properties. Accordingly, the estimates are expected to change as future
information becomes available. The estimates have been prepared by the Company's
internal petroleum reservoir engineers.

(E) STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS AND CHANGES THEREIN
    RELATING TO PROVED OIL AND GAS RESERVES
 
     The following table, which presents a standardized measure of discounted
future net cash flows and changes therein relating to proved oil and gas
reserves, is presented pursuant to Statement of Financial Accounting Standards
No. 69. In computing this data, assumptions other than those required by the
Financial Accounting Standards Board could produce different results.
Accordingly, the data should not be construed as representative of the fair
market value of the Company's proved oil and gas reserves.
 
     Future cash inflows were computed by applying year end prices of oil and
gas relating to proved reserves to the estimated year end quantities of those
reserves. Future price changes were considered only to the extent provided by
contractual arrangements in existence at year end. Future development and
production costs were computed by estimating the expenditures to be incurred in
developing and producing the proved oil and gas reserves at the end of the year,
based on year end costs. Future income tax expenses were computed by applying
the year end statutory tax rate adjusted for tax credits, with consideration of
future tax rates already legislated, to the future pretax net cash flows
relating to proved oil and gas reserves, less the tax basis of the properties
involved. The standardized measure of discounted future cash flows represents
the present value of estimated future net cash flows using a 10% annual discount
rate.

                        (i)  Such other preferences and relative, 
                participating, optional or other special rights, or 
                qualifications, limitations or restrictions thereof  as shall
                not be inconsistent with this Article  FOURTH. 

                (2)  Except as otherwise required by law and except  for such
        voting powers with respect to the election of  directors or other
        matters as may be stated in the  resolutions of the Board of Directors

        shall  have no voting power whatsoever.

                SECTION B:  Provisions relating to Common Stock:

                (1)  Except as otherwise provided in this Article  FOURTH and
        except as shares  are designated as Class A  Common stock or Class B
        Common Stock as the case may be,  each share of Class A Common Stock
        and each share of Class  B Common Stock shall be identical in all
        respects, shall  have the same powers, preferences and rights without 
        preference of any class or share over any other class or  share, and
        each holder of such shares shall be entitled at  any stockholders'
        meeting to one vote for each such share  standing in his name on the
        books of the Corporation.

                (2)  (a)  Except to the extent otherwise provided in  the  last

        outstanding shares of Class A  Common Stock (and any series of the
        Preferred Stock  entitled to vote for the election of directors) shall
        be  entitled, voting separately (or  together with the  Preferred Stock
        entitled to vote) as a class, to elect the  remaining directors to be
        elected; provided, however, that  this paragraph 2(a) shall not prevent
        the  holders of  shares of Preferred Stock from being entitled, voting 
        separately as a class, to elect not  more than two  directors in case
        dividends on the  Preferred Stock shall  be in default in an amount
        equal to six full quarterly  dividends payable thereon, so long as
        after giving effect  to the election of such two  directors more  than
        one-half   of the directors of the  Corporation shall have been 
        elected by the holders of the shares of Class B Common  Stock.

                (b)  Any director may be removed at any time, either  with or
        without cause, by the affirmative vote of the  holders of record of a
        majority of the issued and  outstanding shares of the class or classes
        of stock of the  Corporation which elected such director or a 
        predecessor  of such director.  A special meeting of the  stockholders

        receipt of written request  therefor signed by or on behalf of the 
        holders of record  of a majority of the issued and outstanding shares
        of the  class or classes of stock of the Corporation which elected 
        such director or his predecessor or  signed by a majority  of the
        directors who were elected by such class or classes.   In the event of
        such removal, the vacancy in the Board of  Directors caused thereby may
        be filled at such meeting by  the affirmative vote of the  holders of
        record of the  issued and outstanding shares of the class or classes of 
        stock of the Corporation the holders of which so removed  such
        director.

                SECTION C.  Provisions relating to all classes of  Stock: 

                (1)  No holder of any class of stock of the  Corporation shall
        have any preemptive right to purchase or  to subscribe for any
        additional issue of stock of the  Corporation of any class, or any
        warrants, options or  rights to purchase any such stock, or any other
        securities  convertible into or exchangeable for, or carrying options 
        or warrants to purchase, stock of any class of the  Corporation. 

                (2)  In the event that any proposed amendment of this 
        Certificate of Incorporation would alter in any manner any 





                                      10

        of the provisions of this  Article FOURTH, then, in  addition
        to any other approvals required by law, by the  provisions of this

        Directors creating any series  of Preferred Stock, the affirmative vote
        of the holders of  record of a majority of the issued and outstanding
        shares  of Class B Common stock, voting separately as a class,  shall
        be necessary to the adoption of such amendment.

and in addition to the powers which may be  conferred by the By-Laws, the Board
of Directors is expressly  authorized: (a)  To make, alter, amend or repeal the

Board of Directors.

                (b)  To remove at any time any officer elected or  appointed by
        the Board of Directors by such vote of the  Board of Directors as may
        be provided for in the By-Laws.   Any other officer of the Corporation
        may be removed at any  time by a vote of the Board of Directors, or by
        any  committee or superior officer upon whom such power of  removal may
        be conferred by the By-Laws or by the vote of  the Board of Directors.

        annual net profits of the Corporation or of its net 





                                      12
<PAGE>   18
        assets in excess of its capital shall be declared in  dividends

                (d)  To fix from time to time the amount of the  profits of the

        extent, and at what time and places and under what  conditions and
        regulations the accounts and books of the  Corporation (other than the

        stockholders; and   no stockholder shall have any right to inspect any
        account  or book or  document of the Corporation, except as  conferred

        of the stockholders.

        amount of their respective participations.

                (g)  To authorize, and cause to be executed,  mortgages and
        liens upon the real and personal property of  the Corporation.

<PAGE>   19
Corporation and any other corporation and no other act of the 
Corporation with relation to any other  corporation shall, in  the absence of
fraud, in any way be invalidated or otherwise  affected by the fact that any
one or more of the directors of  the Corporation are pecuniarily or otherwise
interested in, or  are directors or officers of, such other corporation.  Any 
director of the Corporation individually, or any firm or  association of which
any director may be a member, may be a  party to, or may be pecuniarily or
otherwise interested in, any  contract or transaction of the Corporation,
provided that the  fact that he individually or as a member of such firm or 
association is such a party or so interested and the extent of  such interest
shall be disclosed or shall have been known to a  majority of the whole Board
of Directors present at any meeting  of the Board of Directors at  which action
upon any such  contract or transaction shall be taken; and any director of the 
Corporation who is also a director or officer of such other  corporation or who
is such a party or so interested may be  counted in determining the existence
of a quorum at any meeting  of  the  Board  of  Directors  which  shall 
authorize any  such  contract or  transaction,  with  like  force and  effect
as if  he were not such director or officer of such other corporation  or not
so interested.  Any director of the Corporation may vote  upon any contract or
other transaction between the Corporation  and any subsidiary or affiliated
corporation without regard to  the fact that he is also a director of such
subsidiary or  affiliated corporation.

        ELEVENTH:  The corporation shall indemnify its  directors, officers,
agents,  and employees to the fullest  extent permitted under Delaware General
Corporation Law, as the  same exists or may hereafter be amended.


        The rights conferred on any person by the preceding  sentence shall not
be exclusive of any other right which such  person may have or hereafter
acquire under any statute,  provision of this Certificate of Incorporation,
Bylaws,  agreement, vote of stockholders or disinterested directors or 
otherwise. The Corporation may maintain insurance, at its  expense, to protect
itself and any director, officer, employee  or agent of the Corporation or
another  corporation,  partnership, joint venture, trust, other  enterprise or 
committee against any  expense, liability or loss, whether or  not the
Corporation would have the power to indemnify such  person against such
expense, liability or loss under the  Delaware General Corporation Law.

        No director of the Corporation shall be liable to the  Corporation or
it stockholders for monetary damages for breach  of fiduciary duty as a
director, except for liability (i) for  any breach of the directors' duty of
loyalty to the Corporation  or its stockholders, (ii) for acts or omissions not
in good  faith or which involve intentional misconduct or a knowing  violation
of law, (iii) under Section 174 of the Delaware  General Corporation Law, or
(iv) for any transaction from which 





                                      15
<PAGE>   21
the director derived an improper personal benefit.

        Neither the amendment nor repeal of this Article  ELEVENTH, nor the
adoption of any  provision of the  Corporation's Certificate of Incorporation
inconsistent with  this Article ELEVENTH, shall eliminate or reduce the effect
of  this Article ELEVENTH in respect of any matter  occurring, or  any cause of
action, suit or claim that, but for this Article  ELEVENTH, would accrue or
arise, prior to such  amendment,  repeal or adoption of an inconsistent
provision.

        TWELFTH:  Each officer, director, or member of any  committee
designated by the Board of Directors shall, in the  performance of his duties,
be fully  protected in relying in  good faith upon the books of accounts or
reports made to the  Corporation by any of its officials or by an independent
public  accountant or by an appraiser selected with reasonable care by  the
Board of  Directors or by any  such  committee or in relying  in good faith upon
other records of the Corporation.

        THIRTEENTH:  Both the stockholders and the directors  of the
Corporation may, if the By-Laws so provide, hold their  meeting and the
corporation may have an office or offices and  may keep its books (except such
as are required by the laws of  the State of Delaware to be kept in Delaware)
within or without  the State of Delaware, at such place or places as may from
time  to time be designated by the Board of Directors.

        FOURTEENTH:  The Corporation hereby reserves the  right to amend,
alter, change or repeal any provision contained  in this Certificate of
Incorporation in the manner now or 





                                      16
<PAGE>   22
hereafter prescribed by the laws of the State of Delaware and  all
rights conferred on  stockholders therein are granted  subject to this
reservation.

     Section 4.  Notice of Meetings.  Except as otherwise 
expressly required by law, notice of each meeting of stock holders,
whether annual or special,  shall be given at least

meeting, shall state briefly the objects or purposes thereof.  
Notice of any meeting of stockholders shall not be required to

ten days before every election of directors, a complete list

specified at the place where said election is to be held to 
the examination of any stockholder and shall be produced and 
kept at the time and  place of the election during the whole 
time thereof and subject to the inspection of any stockholder 
who may be present.   The original or a duplicate stock ledger 
shall be the only evidence as to who are the stockholders 
entitled to examine such list or the books of the Corporation 
or to vote in person or by proxy at such election.

     Section 6.  Quorum.  At each meeting of the stockholders, 
the holders of record of 25% of the issued and outstanding 
stock of the Corporation entitled to vote at
such meeting, present in person or by proxy, shall constitute 
a quorum for the transaction of business,  except where 
otherwise provided by law, the Certificate of Incorporation 
or these Bylaws.  In the event that any business to be 




                                      4
<PAGE>   5
transacted at such meeting requires the affirmative vote of 
any class of stock of the Corporation, 25% of the issued and 
outstanding stock of such class, present in person or by 
proxy, shall constitute a quorum for the transaction of such 
business, except where otherwise provided by law, the 
Certificate of Incorporation or these Bylaws.  In the absence 
of a quorum, any officer entitled to preside at, or act as 
Secretary of, such meeting, shall have the power to adjourn 
the meeting from time to time until a quorum shall be 
constituted.   At any such adjourned meeting at which a quorum

but only those stockholders entitled to vote at the meeting as 
originally noticed shall be entitled to vote at any 
adjournment or adjournments thereof.

     Section 7.  Voting.  At every meeting of stockholders 
each holder of record of the issued and outstanding stock of 
the Corporation entitled to vote at such meeting shall be 
entitled to one vote in person or by proxy for each  such 
share of stock entitled to vote held by such stockholder, 
but no proxy shall be voted after three years from its date, 
unless the proxy provides for a longer period and, except 
where the transfer books of the Corporation shall have been 
closed or a date shall have been fixed as the record date for 
the determination of stockholders entitled to vote, no share 
of stock shall be voted on at any election for directors which 




                                      5
<PAGE>   6
shall have been transferred on the books of the Corporation 
within twenty days next preceding such election of directors.  
Shares of its own capital stock belonging to the Corporation 
directly or indirectly shall not be voted upon directly or 
indirectly.  At all meetings of the stockholders, quorum being 
present, all matters shall be decided by a majority vote of 
the shares of stock entitled to vote held by stockholders 
present in person or by proxy,  except as otherwise required 
by the laws of the State of Delaware and except  as otherwise 
specified in the Certificate of Incorporation of the 
Corporation.  Unless demanded by a stockholder of the 
Corporation present in person or by proxy at any meeting of 
the stockholders and entitled to vote thereat or so directed 
by the Chairman of the meeting or required by the laws of the 
State of Delaware, the vote thereat on any question need not 
be by ballot.  On a vote by ballot, each ballot shall be 
signed by the stockholder voting,  or in his name by his 
proxy, if there be such proxy, and shall state the number of 
shares voted by him.   Whenever the vote of stockholders at a 
meeting thereof is required or permitted to be taken in 
connection with any corporate action by any provisions of the 
laws of the State of Delaware or of the Certificate of 
Incorporation or of  these Bylaws, the meeting and vote of 
stockholders may be dispensed with,  if a majority of the stockholders 
who would have been entitled to vote upon the action if such 




                                      6
<PAGE>   7
meeting were held, shall consent in writing to such corporate 
action being taken.

stockholders.  Each director shall hold office until the 
annual meeting of the stockholders next following his election 
and until his successor shall have been elected and shall 
qualify,  or until his death, resignation, or removal.

     Section 3.  Quorum and Manner of Acting.  Unless 
otherwise provided by law,  the presence of one-third of the 
whole Board of Directors,  and in any case not less than three 
directors, shall be necessary to constitute a quorum for the 
transaction of business.  In the absence of a quorum, a 
majority of the directors present may adjourn the meeting from 
time to time until a quorum shall be present.  Notice of any 
adjourned meeting need not be given.  At all meetings of 
directors, a quorum being present, all matters shall be 
decided by the affirmative vote of a majority of the directors 
present, except as otherwise required by the laws of the State

have been lost, stolen, mutilated or destroyed, the Board of 
Directors, in its discretion, may require the owner of any 
such certificate, or his legal representatives, to give the 
Corporation a bond in such  sum and in such form as it may 
direct, to indemnify the Corporation against any claim that 
may be made against it on account of the alleged loss, theft, 
mutilation or destruction of any such certificate or the 
issuance of  such new certificate.  Proper and legal evidence 
of such loss, theft, mutilation or destruction shall be

obtaining such consent, as a record date for the determination
of the stockholders entitled to notice of, and to vote 
at, such meeting, and any adjournment thereof, or to receive 
payment of any dividend, or to receive any such allotment of 
rights, or to exercise the rights in respect of any such 
change, conversion, or exchange of capital stock or to give 
such consent, as the case may be, notwithstanding any 
transfer of any stock on the books of   the Corporation after 


                                      23
<PAGE>   24

    that pay period.                                               

Thrift Contributions shall be made by uniform payroll 
deductions which the Participant shall in writing authorize 
his Employer to withhold from his Basic Compensation and     
pay over to the Trustee.  Deferred Compensation Contributions 
shall be made by uniform payroll deductions pursuant to a  
Basic Compensation reduction agreement between the Participant 
and his Employer which authorizes the Employer to pay such 
contribution to the Trustee on behalf of the Participant.  A 
Participant may change the applicable percentage of payroll 
deductions as of any January 1, or as of any payday suspend  
for a period of at least six months his election to make  
Thrift Contributions or to have Deferred Compensation 
Contributions made on his behalf, provided (1) that written 
notice of such change or suspension is delivered to his 
Employer at least thirty days prior to the effective date 
thereof, and (2) that such a suspension may be made by a 
Participant only once within any period of thirty-six months.  
A Participant's elected contributions shall automatically 
resume upon the expiration of his designated




                                     -13-

suspension period.  No retroactive contributions may be made by 
or on behalf of a Participant.

    Section 3.2  Employer Matching Contributions.  For each  
pay period an Employer shall, out of its Net Profits, make a 
Matching Contribution to the Plan for each Participant in its 
employ in an amount which, when added to any forfeiture amount 
being credited to such Participant for that pay period, will 
equal the lessor (1) 5% of such Participant's Basic 
Compensation for that pay period, or (2) the total amount of 
the Thrift and Deferred Compensation Contributions made by or 
on behalf of such Participant for that pay period.

    Section 3.3  Tax Credit Contributions.  For each Plan Year 
commencing after December 31, 1982, each Employer shall, out of 
its Net Profits, make a Tax Credit Contribution to the Plan in 
an amount equal to the following applicable percentage of the 
aggregate Compensation for that Plan Year of all Participants 
who were in the employ of such Employer on the last day of that 
year, or whose employment with such Employer terminated during 
that year by reason of death or by reason of retirement under 
the normal or early retirement or disability benefit provisions 
of a pension or retirement plan of an Employer or Affiliated 
Company:

The Tax Credit Contribution made to the Plan for a Plan Year 
shall be allocated among the Participants who were in the 
employ of an Employer on the last day of such year, or whose 
employment with such Employer terminated during that year by 
reasons of death or by reason of retirement under the normal or 
early retirement or disability benefit provisions of a pension 
or retirement plan of an Employer or Affiliated Company, in the 
proportion that the Compensation received by each such 
Participant during that year (disregarding any Compensation in 
excess of the first $100,000) bears to the Compensation 
received by all such Participants during that year 
(disregarding any Compensation in excess of the first $100,000 
for any Participant).

    Section 3.4  Payment to Trustee.  The Thrift and Deferred 
Compensation Contributions made to the Plan for a pay period 
ending within a particular month shall be paid to the Trustee 
in cash no later than thirty days after the end of such month.  
The Matching Contribution made to the Plan for a pay period 
ending within a particular month may be made in cash or in the 
form of Company Stock, or in any combination thereof, and shall 
be paid or transferred to the Trustee no later than thirty days 
after the end of such month.  The Tax Credit Contribution to be




                                     -15-
<PAGE>   19
made to the Plan for a particular Plan Year may be made in cash 
or in the form of Company Stock, or any combination thereof, 
and shall be paid or transferred to the Trustee no later than 
thirty days after the due date (including extensions thereof) 
for the filing of the Employers' federal income tax return for 
such year.  The value of any Company Stock contributed to the 
Plan as a Matching Contribution shall be the closing price of 
such stock on the open market as of the date of contribution if 
such stock was traded on the open market on such date, but if 
such stock was not traded on the open market as of the date of 
the contribution, then the value of the Company Stock shall be 
the closing price of such stock on the open market as of the 
date next preceding the date of the contribution that such 
stock was traded on the open market.  The value of any Company 
Stock contributed to the Plan as a Tax Credit Contribution 
shall be the average of the closing price of such stock, as 
reported on the composite tape for securities listed on the 
American Stock Exchange, Inc., for the twenty consecutive 
trading days immediately preceding the date on which such stock 
is contributed to the Plan.  If any Employer is prevented from 
making a contribution which it would otherwise have made under 
this Plan by reason of having no Net Profits or because such 
Net Profits are less than the contribution which it would 
otherwise have made, than so much of the contribution which 
such Employer was so prevented from making shall be made for




                                     -16-
<PAGE>   20
the benefit of the Participants in the employ of such Employer 
by the other Employers to the extent of their Net Profits in 
such proportions as such other Employers may determine.

    Section 3.5  Crediting of Contributions and Forfeitures.  
The Committee shall establish and maintain a Participant Thrift 
Account, a Company Thrift Account, a Participant Deferred 
Account, a Company Matching Account, an ESOP Account and a 
PAYSOP Account for each Participant.  All Thrift Contributions 
made by a Participant pursuant to Section 3.1(a), all Company 
Stock and other amounts attributable to contributions made by 
such Participant to the Thrift Plan, and all Company Stock and 
other amounts attributable to contributions made by such 
Participant to the Employee Stock Ownership Plan which were not 
Matching Employee Contributions thereunder, shall be allocated 
to such Participant's Participant Thrift Account under this 
Plan.  All Company Stock and other amounts attributable to 
Matching Contributions made by an Employer for a Participant 
pursuant to Section 3.2, and all forfeitures applied pursuant 
to Section 6.7 to reduce the Matching Contributions which would 
otherwise have been made by an Employer for such Participant, 
shall be credited to such Participant's Company Matching 
Account under this Plan.  All Company Stock, Company Class B





                                     -17-
<PAGE>   21
Common Stock and other amounts attributable to contributions 
made by an Employer to the Employee Stock Ownership Plan for a 
Participant, and all Company Stock, Company Class B Common 
Stock and other amounts attributable to contributions made by a 
Participant to the Employee Stock Ownership Plan which were 
Matching Employee Contributions thereunder, shall be credited 
to such Participant's ESOP Account under this Plan.  All Tax 
Credit Contributions allocated to a Participant pursuant to 
Section 3.3 shall be credited to such Participant's PAYSOP 
Account under this Plan.  All Deferred Compensation 
Contributions made by an Employer on behalf of a Participant 
pursuant to Section 3.1(b) shall be credited to such 
Participant's Participant Deferred Account; provided, however, 
that if for any Plan Year commencing after December 31, 1983, 
the actual deferral percentage for the highest paid one-third 
of all Employees eligible to elect to have their Employer make 
a Deferred Compensation Contribution to the Plan for them for 
that year fails to satisfy one of the following tests:

           (a)  the actual deferral percentage for said highest 
  paid one-third of such Employees is not more than the     
  actual deferral percentage for all other such Employees   
  multiplied by 1.5, or                                     

           (b)  the excess of the actual deferral percentage for 
  said highest paid one-third of all such Employees over the    
  actual deferral percentage for all other such Employees is    




                                     -18-
<PAGE>   22
    not more than three percentage points, and the actual  
    deferral percentage for said highest paid one-third of 
    such Employees is not more than the actual deferral 
    percentage  for all other such Employees multiplied by 2.5,
then the 10% maximum percentage of Basic Compensation otherwise 
permitted to be credited to the Participant Deferred Accounts 
of said highest paid one-third of such Employees shall be 
reduced in increments of one-half of one percent until the 
actual deferral percentage for said highest paid one-third of 
such Employees satisfies one of said tests.  For the purposes 
of this Section, the term "actual deferral percentage" for a 
specified group of Employees for a Plan Year means the average 
of the ratios (calculated separately for each Employee in such 
group) of (1) the sum of the amounts of the Deferred 
Compensation Contribution, the Tax Credit Contribution and the 
vested portion of the Matching Contributions (determined as of 
the last day of the Plan Year) made to the Plan for or on 
behalf of each such Employee for that year, to (2) the amount 
of such Employee's Compensation for that year.  Any Deferred 
Compensation Contribution made by an Employer on behalf of a 
Participant pursuant to Section 3.1(b) which cannot be credited 
to the Participant Deferred Account of such Participant because 
of the limitation contained in this Section shall be credited 
to such Participant's Participant Thrift Account.

                TRUST AND INVESTMENT PROVISIONS

    Section 4.1  Trust and Trustee.  All of the contributions 
and other amounts paid to the Trustee pursuant to this Plan, 
together with the income therefrom and the increments thereof, 
shall be held in trust by the Trustee under the terms and 
provisions of the separate trust agreement between InterFirst 
Bank Dallas, N.A., as Trustee, and the Employers, a copy of 
which is attached hereto and incorporated herein by this 
reference for all purposes, establishing a trust fund for the 
exclusive benefit of the Participants and their beneficiaries.

    Section 4.2  Investment of ESOP and PAYSOP Accounts.  All 
Tax Credit Contributions credited to a Participant's PAYSOP 
Account which are paid to the Trustee in cash shall be used by 
the Trustee within thirty days of receipt of purchase Company 
Stock for such Account.  All cash dividends, stock dividends, 
stock splits and other amounts received by the Trustee with 
respect to the Company Stock or other property held for an ESOP 
or PAYSOP Account shall be credited to (and, if cash or 
property other than Company Stock, used as soon as practicable 
to purchase Company Stock for) such Account.

    Section 4.3  Investment of Participant Thrift, Participant 
Deferred, Company Thrift and Company Matching Accounts.  Upon 
becoming a Participant in the Plan each Participant shall 
direct, on a form prescribed by and filed with the Committee, 
that:




                                     -20-
<PAGE>   24
    (a)  The contributions and other amounts credited to  his Participant
    Thrift and Participant Deferred Accounts be  invested, in percentage
    multiples authorized by the  Committee, in Company Stock, PSA Stock and/or
    Government  Bonds; and

    (b)  the contributions and other amounts credited to his Company
    Thrift and Company Matching Accounts be  invested, in percentage multiples
    authorized by the  Committee, in Company Stock and/or PSA Stock.

    If a Participant fails to give such investment direction, 
all contributions and other amounts credited to his Participant 
Thrift and Participant Deferred Accounts shall be invested in 
Government Bonds, and all contributions and other amounts 
credited to his Company Thrift and Company Matching Accounts 
shall be invested in Company Stock.  A Participant may change 
his investment direction with respect to future contributions 
or redirect the investment of one or more of said four Account 
balances on any January 1, provided that written notice of such 
change is delivered to the Committee at least thirty days prior 
to the January 1 as of which such change is to become 
effective.  All cash dividends, stock dividends, stock splits, 
interest and other amounts received by the Trustee with respect 
to a particular type of security held for a Participant Thrift, 
Participant Deferred, Company Thrift or Company Matching 
Account shall be credited to (and, if cash or property other 




                                     -21-
<PAGE>   25
than the security from which it was derived, used as soon as 
practicable to purchase said security for) such Account.

    Section 4.4  Purchases of Company and PSA Stock and 
Government Bonds.  Company Stock may be purchased by the 
Trustee in the open market or from the Company.  If Company 
Stock is purchased from the Company, the price of such Company 
Stock shall be the closing price of Company Stock on the open 
market as of the date of the purchase if such stock was traded 
on the open market on such date, or if such stock was not 
traded on the open market as of the date of the purchase, then 
the price of such Company Stock shall be the closing price of 
Company on the open market as of the date next preceding the 
date of the purchase that such stock was traded on the open 
market.  PSA Stock shall be purchased by the Trustee in the 
open market.  Investments in Government Bonds shall be made 
subject to such rules and regulations as may from time to time 
be established by the Committee.  Any cash in the hands of the 
Trustee at any time and not invested may be held by the Trustee 
for the Accounts of the Participants to whom it is attributable 
without obligation to credit interest thereon.  The Trustee 
shall add to the cost of securities purchased any brokerage 
commissions, transfer taxes and other charges or expenses 
incident thereto, or deduct from the gross proceeds from the 
sale of securities, any such charges incident thereto.  The 
cost to a Participant's Account of securities purchased shall




                                     -22-
<PAGE>   26
be the average cost of all securities of the particular issue 
purchased by the Trustee during the calendar month in which the 
securities shall have been purchased for Participants' 
Accounts.  In case of the redemption of any nontransferrable 
Government Bond or on the maturity thereof, the Participant for 
whose Account such Government Bond was purchased shall take 
such steps as the Trustee may prescribe in order to effect the 
redemption or collection thereof by the Trustee.

    Section 4.5  Voting Rights.  Each Participant shall be 
entitled to direct the Trustee as to the manner in which any 
rights (including but not limited to voting rights, 
subscription rights and conversion privileges) with respect to 
the Company Stock and Company Class B Common Stock credited to 
such Participant's ESOP and PAYSOP Accounts are to be 
exercised.  For this purpose, the Committee shall notify each 
Participant of each annual or special meeting of the 
shareholders of the Company and of any other occasion for the 
exercise of voting or other rights by such shareholders, not 
later than the date prior to such meeting or other occasion on 
which the Company notifies its other shareholders.  The 
notification shall include a copy of any proxy solicitation 
material and other information which the Company distributes to 
shareholders regarding the exercise of voting or other rights, 
together with a form requesting instructions to the Trustee as 
to how the Participant's rights are to be exercised.  The 




                                     -23-
<PAGE>   27
Trustee shall tabulate the instructions received and shall vote 
or otherwise exercise rights with respect to said shares of 
stock as instructed.  The Trustee shall not vote or otherwise 
exercise rights with respect to any of said shares of stock as 
to which no instructions from Participants have been duly 
received.

                          ARTICLE V.

                VESTING AND DISTRIBUTION EVENTS

    Section 5.1  Retirement or Disability.   Upon the 
Retirement of a Participant or in the event of a Participant's 
Permanent Disability while employed by or on authorized leave 
of absence from an Employer or Affiliated Company, the amounts 
credited to all Accounts maintained for such Participant shall 
be fully vested and distributed to him in accordance with the 
provisions of Article VI.

    Section 5.2  Death.  Upon the death of a Participant, the 
amounts credited to all Accounts maintained for such 
Participant shall be fully vested and distributed to his 
beneficiary or beneficiaries in accordance with the provisions 
of Article VI.

    Section 5.3  Break in Service.  If a Participant incurs a 
Break in Service prior to his Retirement, Permanent Disability 
or death, such Participant shall be entitled to receive the 
full amount credited to his Participant Thrift, Participant 
Deferred ESOP and PAYSOP Accounts, plus the following portion 




                                     -24-
<PAGE>   28
of the amount credited to his Company Thrift and Company 
Matching Accounts, depending upon the number of Years of 
Service completed by such Participant on the date of such 
separation from employment:

          Years of Service           Percentage Vested
          ----------------           -----------------
             Less Than 3                   None
                 3                          60%
                 4                          80%
             5 or More                     100%

provided, however, that notwithstanding the foregoing schedule, 
a Participant's Company Thrift and Company Matching Accounts 
shall be fully vested on and after  the day such  Participant 
is entitled to receive under this Section shall be distributed 
to such Participant in accordance with the provisions of 
Article VI, and the balance of such Participant's Company 
Thrift and Company Matching Accounts shall be forfeited.


                          ARTICLE VI.

                 DISTRIBUTIONS AND FORFEITURES

    Section 6.1  Time and Form of Distribution.  The 
distribution of amounts withdrawn by or otherwise due to a 
Participant or beneficiary under the Plan shall be made as soon 
as practicable after such Participant or beneficiary becomes 
entitled to distribution, but unless the Participant elects 
otherwise with the consent of the Committee, in no event later 
than sixty days after the end of the Plan Year during which  




                                     -25-
<PAGE>   29
such Participant or beneficiary becomes entitled to such 
distribution.  The portion of any Account invested in 
Government Bonds will be distributed in the form of such bonds 
or in cash, or in any combination thereof, as determined by the 
Committee in its absolute discretion.  The portion of any 
Account (other than an ESOP or PAYSOP Account) invested in 
Company stock will be distributed in the form of such stock or 
in cash, or in any combination thereof, as determined by the 
Committee in its absolute discretion.  The portion of any 
Account invested in PSA Stock will be converted into cash and 
distributed in the form of cash or in the form of Company 
Stock, or in any combination thereof, as determined by the 
Committee in its absolute discretion.  All amounts credited to 
an ESOP or PAYSOP Account will be distributed in the form of 
Company Stock (with cash in lieu of fractional shares).  If any 
portion of an ESOP Account is invested in shares of Company 
Class B Common Stock and a withdrawal or other distribution 
event occurs with respect to said shares, prior to any 
distribution from such ESOP Account the Participant or 
beneficiary to whom such distribution would otherwise be made 
shall instruct the Trustee in writing either to "put" said 
shares of stock to the Company for cash or to exchange said 
shares of stock with the Company for Company Stock on a 
share-for-share basis.  If the "put" is elected, the per share 
value of Company Class B Common Stock shall be deemed to be




                                     -26-
<PAGE>   30
equal to the average closing price per share of Company Stock, 
as reported on the composite tape for securities listed on the 
American Stock Exchange, Inc., for the twenty consecutive 
trading days immediately preceding the date on which such "put" 
is exercised.  Any Company or PSA Stock which is to be 
converted into cash for distribution to a Participant or 
beneficiary shall be sold by the Trustee in the open market 
during the month following the date as of which such withdrawal 
or other distribution event occurs.  The amount of cash to be 
distributed to the Participant or beneficiary with respect to 
such Company or PSA Stock shall be determined on the basis of 
the average net proceeds per share (i.e., gross proceeds from 
the sale less any brokerage commissions, transfer taxes and 
other expenses incident thereto) realized by the Trustee upon 
such sales during said month.  In lieu of making such sale in 
the open market, the Trustee in its discretion may match such 
sales with purchases to be made for such month pursuant to the 
Plan, with the prices of any such matched sales and purchases 
being determined in the same manner as provided in section 4.4 
for determining the price of Company Stock purchased from the 
Company.

    Section 6.2  Distribution of Retirement, Disability and 
Death Benefits.  Any amount payable to a Participant under the 
Plan upon his Retirement or Permanent Disability shall be 
distributed to such Participant in a single distribution.  Any




                                     -27-
<PAGE>   31
amount payable under the plan upon the death of a Participant 
shall be distributed in a single distribution to the 
beneficiary or beneficiaries designated by such Participant.  
Such designation of beneficiary or beneficiaries shall be made 
in writing on a form prescribed by the Committee and, when 
filed with the Committee, shall become effective and remain in 
effect until changed by the Participant by the filing of a new 
beneficiary designation from with the Committee.  If a 
Participant fails to so designate a beneficiary, or in the 
event all of the designated beneficiaries are individuals who 
predeceased the Participant, then the Committee shall direct 
the Trustee to distribute the amount payable under the Plan in 
a single distribution to the estate of such deceased 
Participant.

    Section 6.3  Withdrawals by Vested Participants.  Subject 
to such conditions, limitations and procedures as the Committee 
may from time to time prescribe for application to all Vested 
Participants on a uniform and nondiscriminatory basis, by 
filing a written notice of withdrawal with the Committee prior 
to the end of any month a Vested Participant may withdraw:

         (a)(1)  all or any portion of the amount credited to 
         his Participant Thrift Account as of the end of such month, 
         and (2) if no amount will remain credited to his 
         Participant Thrift Account following such withdrawal, all 
         or any portion of the amount credited to his Company Thrift




                                     -28-
<PAGE>   32
Account as of the end of such month, and if such 
Participant has either attained the age of 59-1/2 years or 
is not in the employ of or on authorized leave of absence 
from an Employer or Affiliated Company, all or any portion 
of the amounts credited to his Participant Deferred and 
Company Matching Accounts as of the end of such month;

     (b)  from his ESOP Account, (1) all or any portion of 
(i) the Company Stock and/or Company Class B Common Stock 
representing Employer contributions which have been 
allocated to such Account (or such Participant's Account 
under the Employee Stock Ownership Plan) as of the end of 
such month for a period of at least 84 months after the 
month as of which such allocation was made, (ii) the 
Company Stock and/or Company Class B Common Stock 
representing Participant contributions which have been 
allocated to such Account (or such Participant's Account 
under the Employee Stock Ownership Plan) as of the end of 
such month for a period of at least 84 months after the 
month as of which such allocation was made, and (iii) the 
Company Stock which has been purchased with Trust income or 
represents dividends paid in Company Stock and which has 
been credited to such Account as of the end of such month, 
or (2) if such Participant is not in the employ of or on 
authorized leave of absence from an Employer or Affiliated 
Company at the end of such month, all (but not less than 




                                     -29-
<PAGE>   33
all) of the Company Stock and Company Class B Common Stock 
credited to such Account;

     (c)  form his PAYSOP Account, (1) if he has attained 
the age of 59-1/2 years, all or any portion of (i) the 
Company Stock representing Employer contributions which 
have been allocated to such Account as of the end of such 
month for a period of at least 84 months after the month as 
of which such allocation was made, and (ii) the Company 
Stock which has been purchased with Trust income or 
represents dividends paid in Company Stock and which has 
been credited to such Account as of the end of such month, 
or (2) if such Participant is not in the employ of or on 
authorized leave of absence from an Employer or Affiliated 
Company at the end of such month, all (but not less than 
all) of the Company Stock credited to such Account;

     (d)  from his Participant Deferred and Company 
Matching Accounts, if such notice of withdrawal requests a 
distribution to alleviate a hardship (within the meaning of 
Section 401(k)(2)(B) of the Code and the regulations 
promulgated thereunder) of such Vested Participant which is 
evidenced to the satisfaction of the Committee, such amount 
as the Committee shall determine to be necessary to meet 
the immediate financial need created by said hardship and 
not reasonably available from other sources.

Subject to such conditions, limitations and procedures as the 
Committee may from time to time prescribe for application to 
all Partially Vested Participants on a uniform and 
nondiscriminatory basis, a Partially Vested Participant may 
withdraw all (but not less than all) of the aggregate value of 
his Participant Thrift Account and the vested portion of his 
Company Thrift Account as of the end of any month by filing a 
written notice of such withdrawal with the Committee prior to 
the end of such month.  Any provision of this Plan to the 
contrary notwithstanding:

         (a)  if the Partially Vested Participant making a 
         withdrawal pursuant to this Section is in the employ of or 
         on authorized leave of absence from an Employer or 
         Affiliated Company at the end of the month as of which such 
         withdrawal is made, (1) no Thrift, Deferred Compensation or 
         Matching Contributions shall be made by, for or on behalf 
         of such Partially Vested Participant for a period of six 
         months following the month as of the end of which such 
         withdrawal was made, and (2) the vested portion of such 
         Participant's Company Thrift Account at all times after the 
         making of such withdrawal shall be determined by the 
         formula P(AB+D)-D, where P is such Participant's vested 
         percentage at the relevant time, AB is the value of said 
         Account at the relevant time, and D is the total amount 
         previously withdrawn from said Account; or




                                     -31-
<PAGE>   35
        (b)  if the Partially Vested Participant making a  withdrawal pursuant
    to this Section is not in the employ of  or on authorized leave of absence
    from an Employer or Affiliated Company at the end of the month as
    of which such  withdrawal is made, upon such withdrawal the unvested 
    portion of such Partially Vested Participant's Company  Thrift Account
    shall be forfeited; provided, however, that  if such Partially Vested
    Participant repays the full amount  of such withdrawal prior to incurring a
    Break in Service  and within two years of the date he is first credited
    with  an Hour of Service following such withdrawal, the amount so 
    forfeited shall be restored to his Company Thrift Account  by an additional
    Employer contribution.

    In addition to the foregoing, a Partially Vested 
Participant who is not in the employ of or on authorized leave 
of absence from an Employer or Affiliated company may withdraw 
all (but not less than all) of the Company Stock and Company 
Class B Common Stock credited to his ESOP and PAYSOP Accounts, 
and all (but not less than all) of the aggregate value of his 
Participant Deferred Account and the vested portion of his 
Company Matching Account .  Upon the withdrawal by a Partially 
Vested Participant of said aggregate value of his Participant 
Deferred Account and the vested portion of his Company Matching 
Account, the unvested portion of his Company Matching Account 
shall be forfeited; provided, however, that if such Partially




                                     -32-
<PAGE>   36
Vested Participant repays the full amount of such withdrawal 
prior to incurring a Break in Service and within two years of 
the date he is first credited with an Hour of Service following 
such withdrawal, the amount so repaid shall be credited to his 
Participant Thrift Account and the amount so forfeited shall be 
restored to his Company Thrift Account by an additional 
Employer contribution.

    Section 6.5  Withdrawals by Nonvested Participants.
Subject to such conditions, limitations and procedures as the 
Committee may from time to time prescribe for application to 
all Nonvested Participants on a uniform and nondiscriminatory 
basis, a Nonvested Participant may withdraw all (but not less 
than all) of the value of his Participant Thrift Account as of 
the end of any month by filing a written notice of such 
withdrawal with the Committee prior to the end of such month.  
Any provision of this Plan to the contrary notwithstanding, if 
a Nonvested Participant makes a withdrawal pursuant to this 
Section:

              (a)  no Thrift, Deferred Compensation or Matching 
         Contributions shall be made by, for on behalf of such 
         Nonvested Participant for a period of six months following 
         the month as of the end of which such withdrawal was made;
         and

              (b)  upon the making of such withdrawal the entire 
         value of such Nonvested Participant's Company Thrift 




                                     -33-
<PAGE>   37
    Account shall be forfeited; provided, however, that if such  Nonvested
    Participant repays the full amount of such  withdrawal prior to incurring a
    Break in Service and within two years of the date he is first
    credited with an Hour of  Service following such withdrawal, the amount so
    forfeited  shall be restored to his Company Thrift Account by an 
    additional Employer contribution.

    In addition to the foregoing, a Nonvested Participant who 
is not in the employ of or on authorized leave of absence from 
an Employer or Affiliated Company may withdraw all (but not 
less than all) of the Company Stock and Company Class B Common 
Stock credited to his ESOP and PAYSOP Accounts, and all (but 
not less than all) of the value of his Participant Deferred 
Account.  Upon the withdrawal by a Nonvested Participant of the 
value of his Participant Deferred Account, the entire value of 
his Company Matching Account shall be forfeited; provided, 
however, that if such Nonvested Participant repays the full 
amount of such withdrawal prior to incurring a Break in Service 
and within two years of the date he is first credited with an 
Hour of Service following such withdrawal, the amount so repaid 
shall be credited to his Participant Thrift Account and the 
amount so forfeited shall be restored to his Company Thrift 
Account by an additional Employer contribution.

    Section 6.6  Break in Service Distribution.  The Vested 
Interest of a Participant which has not been previously




                                     -34-
<PAGE>   38
distributed or withdrawn in accordance with the provisions of 
this Article shall be distributed in a single distribution to 
such Participant upon his incurring a Break in Service.  The 
then unvested portions of a Participant's Company Thrift and 
Company Matching Accounts shall be permanently forfeited when 
he incurs a Break in Service.

    Section 6.7  Application of Forfeitures.  Any forfeitures 
resulting under the provisions of this Article shall be 
credited to a Forfeiture Account and thereafter applied to 
reduce the earliest subsequent Matching Contributions the 
Employers would otherwise be required to make to the Plan: 
provided, however, that if the Plan is terminated, any 
forfeited amounts not then so applied shall be credited ratably 
among the Accounts (other than ESOP and PAYSOP Accounts) 
remaining in the Plan at the time of such termination.

    Section 6.8  Distributions to Minors and Persons Under 
Legal Disability.  If any distribution under the Plan becomes 
payable to a minor or other person under a legal disability, 
such distribution shall be made to the duly appointed guardian 
or other legal representative of the estate of such minor or 
person under legal disability.

                          ARTICLE VII

                      PLAN ADMINISTRATION

    Section 7.1  Appointment of Committee.  This Plan shall be 
administered on behalf of all Employers by a Committee composed 




                                     -35-
<PAGE>   39
of at least three individuals appointed by the Board of 
Directors of the Company.  Each member of the Committee so 
appointed shall serve in such office until his death, 
resignation or removal by the Board of Directors of the 
Company.  The Board of Directors of the Company may remove any 
member of the Committee at any time by giving written notice 
thereof to the members of the Committee.  Vacancies shall 
likewise be filled from time to time by the Board of Directors 
of the Company.  The members of the Committee shall receive no 
remuneration from the Plan for their services as Committee 
members.

    Section 7.2  Powers and Duties of the Committee.  The 
Committee shall interpret and implement the provisions of the 
Plan, and shall perform all of the duties and may exercise all 
of the powers and discretion granted to it under the terms of 
the Plan.  The Committee shall act by a majority of its members 
at the time in office and such action may be taken either by a 
vote at a meeting or in writing without a meeting.  The 
Committee may by such majority action authorize any one or more 
of its members to execute any document or documents on behalf 
of the Committee, in which event the Committee shall notify the 
Trustee in writing of such action and the name or names of its 
member or members so authorized to act.  Every interpretation, 
choice, determination or other exercise by the Committee of any 
power or discretion given either expressly or by implication to




                                     -36-
<PAGE>   40
it shall be conclusive and binding on all parties directly or 
indirectly affected, without restriction, however, on the right 
of the Committee to reconsider and redetermine such actions.  
In performing any duty or exercising any power herein 
conferred, the Committee shall in no event perform such duty or 
exercise such power in any manner which discriminates in favor 
of Employees who are officers, shareholders or highly 
compensated employees of an Employer.

    Section 7.3  Rules, Records and Reports.   The Committee 
may adopt such rules and regulations for the administration of 
the Plan as are consistent with the terms hereof, and shall 
keep adequate records of its proceedings and acts and of the 
status of the Participants' Accounts.  The Committee may employ 
such agents, accountants and legal counsel (who may be agents, 
accountants or legal counsel for an Employer) as may be 
appropriate for the administration of the Plan.  The Committee 
shall annually provide each Participant with a report 
reflecting the status of his Accounts under the Plan and shall 
cause such other information, documents or reports to be 
prepared, provided and/or filed as may be necessary to comply 
with the provisions of the Code, ERISA or other applicable law.

    Section 7.4  Administration Expenses and Taxes.   Unless 
otherwise paid by the Employers in their discretion, the 
Committee shall direct the Trustee to pay all reasonable and 
necessary expenses (including the fees of agents, accountants




                                     -37-
<PAGE>   41
and legal counsel) incurred by the Committee in connection with 
the administration of the Plan.  Should any tax of any 
character (including transfer taxes) be levied upon the Trust 
assets or the income therefrom, such tax shall be paid from and 
charged against the assets of the Trust.

    Section 7.5  Claims Procedure.   If any Participant or 
beneficiary (hereinafter called the "claimant") feels that he 
is being denied a benefit to which he is entitled under the 
Plan, such claimant may file a written claim for said benefit 
with any member of the Committee.  Within sixty days after the 
receipt of such claim the Committee shall determine and notify 
the claimant as to whether he is entitled to such benefit.  
Such notification shall be in writing and, if denying the claim 
for benefit, shall set forth the specific reason or reasons for 
the denial, make specific reference to the pertinent provisions 
of the Plan, and advise the claimant that he may, within sixty 
days of the receipt of such notice, in writing request to 
appear before the Committee or its designated representative 
for a hearing to review such denial.  Any such hearing shall be 
scheduled at the mutual convenience of the Committee or its 
designated representative and the claimant, and at such hearing 
the claimant and/or his duly authorized representative may 
examine any relevant documents and present evidence and 
arguments to support the granting of the benefit being
claimed.  The final decision of the Committee with respect to




                                     -38-
<PAGE>   42
the claim being reviewed shall be made within sixty days 
following the hearing thereon and the Committee shall in 
writing notify the claimant of its final decision, again 
specifying the reasons therefor and the pertinent provisions of 
the Plan upon which such decision is based.  The final decision 
of the Committee shall be conclusive and binding upon all 
parties having or claiming to have an interest in the claim 
being reviewed.

                         ARTICLE VIII.

                   AMENDMENT AND TERMINATION

    Section 8.1  Amendment.  The Company shall have the right 
and power at any time and from time to time to amend this Plan, 
in whole or in part, on behalf of all Employers.  With the 
consent of the company, each Employer shall have the right and 
power at any time and from time to time to amend this Plan, in 
whole or in part, with respect to the Plan's,  application to 
the Participants of the particular amending Employer and the 
assets held in the Trust for their benefit, or to transfer such 
assets or any portion thereof to a new trust for the benefit 
of such Participants.  However, in no event shall any amendment 
or new trust permit any portion of the trust fund to be used 
for or diverted to any purpose other than the exclusive benefit 
of the Participants and their beneficiaries, nor shall any 
amendment or new trust deprive any Participant of his Vested 
Interest under the Plan.  The Employers shall in writing notify 




                                     -39-
<PAGE>   43
the Committee of any amendment or change in the provisions of 
the Plan.

    Section 8.2  Termination.   Each Employer may at any time 
terminate this Plan as it applies to the Participants of such 
Employer by giving written notice thereof to the Committee and 
Trustee.  Any provisions of this Plan to the contrary 
notwithstanding, upon the termination or partial termination of 
the Plan as to any Employer, or in the event any Employer 
should completely discontinue making contributions to the Plan 
without formally terminating it, all amounts credited to the 
Accounts of the affected participants of that particular 
Employer shall be fully vested and nonforfeitable.

                          ARTICLE IX.

               MISCELLANEOUS GENERAL PROVISIONS

    Section 9.1  Spendthrift Provision.   No right or interest 
of any Participant or beneficiary under this Plan may be 
assigned, transferred or alienated, in whole or in part, either 
directly or by operation of law, and no such right or interest 
shall be liable for or subject to any debt, obligation or 
liability of such Participant or beneficiary.

    Section 9.2  Maximum Annual Additional Limitation.   Any 
provision of this Plan to the contrary notwithstanding, the sum 
of (a) the Employer contributions, (b) the lesser of one-half 
of the Participant's contributions (excluding rollover 
contributions) or the Participant's contributions (excluding 




                                     -40-
<PAGE>   44
rollover contributions) in excess of 6% of Compensation and (c) 
the forfeitures allocated to the Accounts of any Participant 
with respect to a Plan Year shall in no event exceed the lesser 
of $30,000 adjusted to take into account any cost-of-living 
adjustment authorized pursuant to Section 415(d) of the Code, 
or 25% of such Participant's Compensation for that year.  For 
the purposes of applying the limitation imposed by this 
Section, an Employer and its Affiliated Companies shall be 
considered a single employer, and all defined contribution 
plans (meaning plans providing for individual accounts and 
benefits based solely on the amounts contributed to such 
accounts and any forfeitures, income, expenses, gains and 
losses allocated to such accounts) described in Section 415(k) 
of the Code, whether or not terminated, maintained by an 
Employer or an Affiliated Company shall be considered a single 
plan.  If the total amount allocable to a Participant's 
Accounts for a Plan Year would, but for this sentence, exceed 
the limitation imposed by this Section, such Participant's 
Thrift Contributions for such year (with the Deferred 
Compensation Contributions made on behalf of such Participant 
for that year being reclassified as Thrift Contributions to the 
extent necessary) shall be refunded to such Participant to the 
extent necessary to permit the maximum permissible allocation 
of ESOP and Matching Contributions to such Participant for that 
year.  Any remaining amount which cannot be allocated to a




                                     -41-
<PAGE>   45
particular Participant for a Plan Year because of the 
limitation imposed by this Section shall be credited to a 
Suspense Account and thereafter reallocated (prior to the 
allocation of forfeitures) to reduce the earliest subsequent 
Matching Contributions the Employers would otherwise be 
required to make to the Plan.

    Section 9.3  Limitations on Responsibilities.  The 
Employers do not guarantee or indemnify the Trust against any 
loss or depreciation of its assets which may occur, nor 
guarantee the payment of any amount which may become payable to 
a Participant or his beneficiaries pursuant to the provisions 
of this Plan.  All payments to Participants and their 
beneficiaries shall be made by the Trustee at the direction of 
the Committee solely from the assets of the Trust and the 
Employer shall have no legal obligation, responsibility or 
liability for any such payments.

    Section 9.4  Committee Indemnification.  The Company will 
indemnify and hold harmless each member of the Committee 
against any claim, cost, expense (including attorney's fees), 
judgment or liability (including any sum paid in settlement of 
a claim with the approval of the Company) arising out of any 
act or omission to act as a member of the Committee under this 
Plan, except in the case of willful misconduct.

    Section 9.5  Employment Noncontractual.  The establishment 
of this Plan shall not enlarge or otherwise affect the terms of




                                     -42-
<PAGE>   46
any Employee's employment with an Employer and an Employer may 
terminate the employment of any Employee as freely and with the 
same effect as if this Plan had not been adopted.

    Section 9.6  Merger or Consolidation.  In no event shall 
this Plan be merged or consolidated into or with any other 
plan, nor shall any of its assets or liabilities be transferred 
to any other plan, unless each Participant would be entitled to 
receive a benefit if the plan in which he then participates 
terminated immediately following such merger, consolidation or 
transfer, which is equal to or greater than the benefit he 
would have been entitled to receive if the Plan had been 
terminated immediately prior to such merger, consolidation or 
transfer.

    Section 9.7  Employee Stock Ownership Plan Merger Into 
Thrift Plan.  The merger of the Employee Stock Ownership Plan 
into the Thrift Plan as contemplated in this Plan is contingent 
upon receiving a determination letter from the Internal Revenue 
Service that this Plan and its related Trust qualify under the 
provisions of Sections 401(a) and (k), 409A and 501(a) of the 
Code.  Any provision of this Plan to the contrary 
notwithstanding, if such determination cannot be obtained 
without the making of amendments to the Plan or its related 
Trust which the Company is unwilling to make, then this Plan 
and its related Trust shall be null and void and the Employee 
Stock Ownership Plan, the Thrift Plan and their respective




                                     -43-
<PAGE>   47
trust agreements shall remain in full force and effect in 
accordance with their respective terms as in effect on December 
31, 1983, with all Thrift and Deferred Compensation 
Contributions made hereunder being considered to have been made 
by Participants to the Thrift Plan, with all Matching 
Contributions made hereunder being considered to have been made 
by the Employers to the Thrift Plan, and with all Tax Credit 
Contributions made hereunder being considered to have been made 
to the Employee Stock Ownership Plan.

    Section 9.8  Applicable Law.  This Plan shall be governed 
and construed in accordance with the laws of the State of Texas 
except where superseded by federal law.

    IN WITNESS WHEREOF, this Plan has been executed at Dallas, 
Texas, on this ______  day of __________________, 1983, to be 
effective as of January 1, 1984.

              Advances for such A Borrowing or any subsequent A Borrowing shall

              of Eurodollar Rate Advances and as a result of circumstances
              referred to in Section 2.02(b)(iii), (iv) or (v) such A Borrowing
              would not consist of Eurodollar Rate Advances, the Borrower may,

              contemplated by Section 2.02(c); and

       (vii)  if the Borrower shall fail to select the duration or continuation

              "Interest Period" in Section 1.01 and this paragraph (b), the

an A Borrowing requested by the Borrower which the related Notice of A
Borrowing specifies is to be comprised of Eurodollar Rate Advances is not made
as an A Borrowing comprised of Eurodollar Rate Advances as a result of Section
2.02(b), the Borrower shall indemnify each Bank against any loss (excluding
loss of profits), cost or expense incurred by such Bank by reason of the
liquidation or reemployment of deposits or other funds acquired by such Bank
(prior to the time such Bank is actually aware that such A Borrowing will not
be so made) to fund the A Advance to be made by such Bank as part of such A
Borrowing.  A certificate in reasonable detail as to the basis for and the
amount of such loss, cost or expense submitted to the Borrower and the Agent by
such Bank shall be prima facie evidence of the amount of such loss, cost or
expense.

       (d)    With respect to any new A Borrowing to be made on the last day of
an Interest Period, the Borrower and each Bank agree that any amounts payable
by the Borrower to such Bank in connection with maturing A Advances on the date
of such Borrowing shall be netted against the amount of the new Borrowing to be
funded by such Bank so as to eliminate where possible the need for actual
payment and readvancement of funds by the parties.  In the event of any A
Borrowing





                                      -15-
<PAGE>   22
subject to the conditions precedent in Section 3.03, unless the Agent shall
have received notice from a Bank prior to the date of such A Borrowing that
such Bank will not make available to the Agent such Bank's ratable portion of
such A Borrowing (to the extent in excess of any maturing A Advances payable to
such Bank), the Agent may assume that such Bank has made such portion available
to the Agent on the date of such A Borrowing in accordance with subsection (a)
of this Section 2.02 and the Agent may, in reliance upon such assumption, make
available to the Borrower on such date a corresponding amount.  If and to the
extent that such Bank shall not have so made such ratable portion available to
the Agent, such Bank and the Borrower severally agree to repay to the Agent
forthwith on demand such corresponding amount together with interest thereon,
for each day from the date such amount is made available to the Borrower until
the date such amount is repaid to the Agent, at (i) in the case of the
Borrower, the interest rate applicable at the time to A Advances comprising
such A Borrowing and (ii) in the case of such Bank, the Federal Funds Rate.  If
such Bank shall repay to the Agent such corresponding amount, such amount so
repaid shall constitute such Bank's A Advance as part of such A Borrowing for
purposes of this Agreement.

       (e)    The failure of any Bank to make the A Advance to be made by it as
part of any A Borrowing shall not relieve any other Bank of its obligation, if
any, hereunder to make its A Advance on the date of such A Borrowing, but no
Bank shall be responsible for the failure of any other Bank to make the A
Advance to be made by such other Bank on the date of any A Borrowing.

       Section 2.03.  Fees.

       (a)    Facility Fee.  The Borrower agrees to pay to each Bank a facility
fee calculated on the amount of such Bank's Commitment (regardless of usage)
from the date hereof until the Termination Date at the Applicable Facility Fee
per annum, payable in arrears on the last day of each calendar quarter during
the term of such Bank's Commitment, and on the Termination Date.

       (b)    Administrative Fee.  The Borrower agrees to pay to the Agent, for
its sole account, an administrative fee as set forth in the Agent's Fee Letter.

       (c)    Bid Request Fee.  The Borrower agrees to pay to the Agent on the
date of each request for B Advances pursuant to Section 2.08 a bid request fee
as set forth in the Agent's Fee Letter.

       (d)    Arrangement Fee.  The Borrower agrees to pay to the Agent on the
date of this Agreement an arrangement fee as set forth in the Agent's Fee
Letter.

       Section 2.04.  Optional Reduction of the Commitments.  The Borrower
shall have the right, upon at least five Business Days notice to the Agent, to
terminate in whole or reduce ratably in part the unused portions of the
respective Commitments of the Banks, provided that each partial reduction shall
be in the aggregate amount of at least $10,000,000, and provided further, that
the aggregate amount of the Commitments of the Banks shall not be reduced to an
amount which is less





                                      -16-
<PAGE>   23
than the aggregate principal amount of the Advances then outstanding.  Any such
reduction or termination of the Commitments shall be permanent.

       Section 2.05.  Repayment and Prepayment of A Advances.  (a) The unpaid
principal amount of each A Advance that is made by each Bank shall be repaid by
the Borrower in full on the last day of the Interest Period for such A Advance.


       (b)    The Borrower may, in respect of Base Rate Advances upon at least
one Business Days' notice, and, in respect of Eurodollar Rate Advances upon at
least three Business Days' notice, to the Agent stating the proposed date
(which shall be a Business Day) and aggregate principal amount of the
prepayment, and if such notice is given the Borrower shall, prepay the
outstanding principal amounts of the A Advances comprising part of the same A
Borrowing in whole or ratably in part, together with accrued interest to the
date of such prepayment on the principal amount prepaid and amounts, if any,
required to be paid pursuant to Section 2.10 as a result of such prepayment;
provided, however, that each partial prepayment pursuant to this Section
2.05(b) shall be in an aggregate principal amount not less than $5,000,000 and
in an aggregate principal amount such that after giving effect thereto no A
Borrowing comprised of Base Rate Advances shall have a principal amount
outstanding of less than $5,000,000 and no A Borrowing comprised of Eurodollar
Rate Advances shall have a principal amount outstanding of less than
$20,000,000.

       Section 2.06.  Interest on A Advances.  The Borrower shall pay interest
on the unpaid principal amount of each A Advance made by each Bank from the
date of such A Advance until such principal amount shall be paid in full, at
the following rates per annum:

       (a)    Base Rate Advances.  If such A Advance is a Base Rate Advance, a
rate per annum equal at all times during the Interest Period for such A Advance
to the Base Rate in effect from time to time during such Interest Period for
such A Advance, payable on the last day of such Interest Period.

       (b)    Eurodollar Rate Advances.  If such A Advance is a Eurodollar Rate
Advance, a rate per annum equal at all times during the Interest Period for
such A Advance to the sum of the Eurodollar Rate for such Interest Period plus
the Applicable Margin in effect from time to time for such A Advance, payable
on the last day of such Interest Period and, if such Interest Period has a
duration of more than three months, on each day which occurs during such
Interest Period every three months from the first day of such Interest Period.

       (c)    Additional Interest on Eurodollar Rate Advances.  The Borrower
shall pay to each Bank, so long as such Bank shall be required under
regulations of the Board of Governors of the Federal Reserve System to maintain
reserves with respect to liabilities or assets consisting of or including
Eurocurrency Liabilities, additional interest on the unpaid principal amount of
each Eurodollar Rate Advance of such Bank, from the date of such Advance until
such principal amount is paid in full, at an interest rate per annum equal at
all times to the remainder obtained by subtracting (i) the Eurodollar Rate for
the Interest Period for such Advance from (ii) the rate obtained





                                      -17-
<PAGE>   24
by dividing such Eurodollar Rate by a percentage equal to 100% minus the
Eurodollar Rate Reserve Percentage of such Bank for such Interest Period,
payable on each date on which interest is payable on such Advance.  Such
additional interest shall be determined by such Bank and notified to the
Borrower through the Agent.  A certificate as to the amount of such additional
interest submitted to the Borrower and the Agent by such Bank shall be
conclusive and binding for all purposes, absent manifest error.

       Section 2.07.  Interest Rate Determination.  (a) Each Reference Bank
agrees to furnish to the Agent timely information for the purpose of
determining each Eurodollar Rate.  If any of the Reference Banks shall not
furnish such timely information to the Agent for the purpose of determining any
such Eurodollar Rate, the Agent shall determine such Eurodollar Rate on the
basis of timely information furnished by the remaining Reference Banks, subject
to Section 2.02(b).

       (b)    The Agent shall give prompt notice to the Borrower and the Banks
of the applicable interest rate for such A Advance determined by the Agent for
purposes of Section 2.06(a) or (b), and the applicable rate, if any, furnished
by each Reference Bank for the purpose of determining the applicable interest
rate under Section 2.06(b).

       Section 2.08.  The B Advances.

       (a) Each Bank severally agrees that the Borrower may make B Borrowings
under this Section 2.08 from time to time on any Business Day during the period
from the date hereof until the date occurring 30 days prior to the Termination
Date in the manner set forth below; provided that, following the making of each
B Borrowing, the aggregate amount of the Advances then outstanding shall not
exceed the aggregate amount of the Commitments of the Banks (computed without
regard to any B Reduction).

       (i)    The Borrower may request a B Borrowing under this Section 2.08 by
              delivering to the Agent, not later than 9:00 A.M. (Dallas time)
              at least five Business Days prior to the date of the proposed B
              Borrowing, a notice of a B Borrowing (a "Notice of B Borrowing"),
              in substantially the form of Exhibit B-2 hereto, specifying the
              date and aggregate amount of the proposed B Borrowing, the
              maturity date for repayment of each B Advance to be made as part
              of such B Borrowing (which maturity date may not be earlier than
              the date occurring 14 days after the date of such B Borrowing or
              later than the earlier of 6 months after the date of such B
              Borrowing or the Termination Date), the interest payment date or
              dates relating thereto, and any other terms to be applicable to
              such B Borrowing (including, without limitation, the basis to be
              used by the Banks in determining the rate or rates of interest to
              be offered by them as provided in paragraph (ii) below and
              prepayment terms, if any, but excluding any waiver or other
              modification to any of the conditions set forth in Article III).
              The Borrower may not select a maturity date for any B Borrowing
              which ends after the Termination Date.  The Agent shall promptly
              notify each Bank of each request





                                      -18-
<PAGE>   25
              for a B Borrowing received by it from the Borrower by sending
              such Bank a copy of the related Notice of B Borrowing.

       (ii)   Each Bank may, if in its sole discretion it elects to do so,
              irrevocably offer to make one or more B Advances to the Borrower
              as part of such proposed B Borrowing at a rate or rates of
              interest specified by such Bank in its sole discretion, by
              notifying the Agent (which shall give prompt notice thereof to
              the Borrower), before 9:00 A.M. (Dallas time) three Business Days
              before the date of such proposed B Borrowing specified in the
              Notice of B Borrowing delivered with respect thereto pursuant to
              paragraph (i) above, of the minimum amount and maximum amount of
              each B Advance which such Bank would be willing to make as part
              of such proposed B Borrowing (which amounts may, subject to the
              proviso to the first sentence of this Section 2.08(a), exceed
              such Bank's Commitment), the rate or rates of interest therefor
              and such Bank's Applicable Lending Office with respect to such B
              Advance; provided that if the Agent in its capacity as a Bank
              shall, in its sole discretion, elect to make any such offer, it
              shall notify the Borrower of such offer before 8:45 A.M. (Dallas
              time) three Business Days before the date of the proposed B
              Borrowing specified in the Notice of B Borrowing delivered with
              respect thereto pursuant to paragraph (i) above.  Any Bank which
              has not notified the Agent of an offer prior to the time
              specified above shall be deemed to have elected not to make such
              an offer.

       (iii)  The Borrower shall, in turn, before 10:00 A.M. (Dallas time)
              three Business Days before the date of such proposed B Borrowing
              specified in the Notice of B Borrowing delivered with respect
              thereto pursuant to paragraph (i) above, either

                     (A)    cancel such B Borrowing by giving the Agent notice
              to that effect, or

                     (B)    accept one or more of the offers made by any Bank
              or Banks pursuant to paragraph (ii) above, in its sole
              discretion, by giving notice to the Agent of the amount of each B
              Advance (which amount shall be equal to or greater than the
              minimum amount, and equal to or less than the maximum amount,
              notified to the Borrower by the Agent on behalf of such Bank for
              such B Advance pursuant to paragraph (ii) above) to be made by
              each Bank as part of such B Borrowing, and reject any remaining
              offers made by Banks pursuant to paragraph (ii) above by giving
              the Agent notice to that effect.

       (iv)   If the Borrower notifies the Agent that such B Borrowing is
              cancelled pursuant to paragraph (iii)(A) above, the Agent shall
              give prompt notice thereof to the Banks and such B Borrowing
              shall not be made.

       (v)    If the Borrower accepts one or more of the offers made by any
              Bank or Banks pursuant to paragraph (iii)(B) above, the Agent
              shall in turn promptly notify (A) each Bank that has made an
              offer as described in paragraph (ii) above, of the date and





                                      -19-
<PAGE>   26
              aggregate amount of such B Borrowing and whether or not any offer
              or offers made by such Bank pursuant to paragraph (ii) above have
              been accepted by the Borrower, (B) each Bank that is to make a B
              Advance as part of such B Borrowing, of the amount of each B
              Advance to be made by such Bank as part of such B Borrowing, and
              (C) each Bank that is to make a B Advance as part of such B
              Borrowing, upon receipt, that the Agent has received forms of
              documents appearing to fulfill the applicable conditions set
              forth in Article III.  Each Bank that is to make a B Advance as
              part of such B Borrowing shall, before 1:00 P.M. (Dallas time) on
              the date of such B Borrowing specified in the notice received
              from the Agent pursuant to clause (A) of the preceding sentence
              or any later time when such Bank shall have received notice from
              the Agent pursuant to clause (C) of the preceding sentence, make
              available for the account of its Applicable Lending Office to the
              Agent at its address referred to in Section 10.02 such Bank's
              portion of such B Borrowing, in same day funds.  Upon fulfillment
              of the applicable conditions set forth in Article III and after
              receipt by the Agent of such funds, the Agent will make such
              funds available to the Borrower at the Agent's aforesaid address.
              Promptly after each B Borrowing the Agent will notify each Bank
              of the amount of the B Borrowing, the consequent B Reduction and
              the dates upon which such B Reduction commenced and will
              terminate.

       (b)    Each B Borrowing shall be in an aggregate amount of not less than
$5,000,000 or an integral multiple of $1,000,000 in excess thereof and,
following the making of each B Borrowing, the Borrower shall be in compliance
with the limitation set forth in the proviso to the first sentence of Section
2.08(a).

       (c)    Within the limits and on the conditions set forth in this Section
2.08, the Borrower may from time to time borrow under this Section 2.08, repay
pursuant to subsection (d) below, and reborrow under this Section 2.08,
provided that no B Borrowing shall be made within three Business Days of the
date of another B Borrowing.

       (d)    The Borrower shall repay to the Agent for the account of each
Bank which has made a B Advance to the Borrower on the maturity date of each B
Advance (such maturity date being that specified by the Borrower for repayment
of such B Advance in the related Notice of B Borrowing delivered pursuant to
subsection (a)(i) above) the then unpaid principal amount of such B Advance.
The Borrower shall not have any right to prepay any principal amount of any B
Advance unless, and then only on the terms, specified by the Borrower for such
B Advance in the related Notice of B Borrowing delivered pursuant to subsection
(a)(i) above and set forth in the B Note evidencing such B Advance.

       (e)    The Borrower shall pay interest on the unpaid principal amount of
each B Advance from the date of such B Advance to the date the principal amount
of such B Advance is repaid in full, at the rate of interest for such B Advance
specified by the Bank making such B Advance in its notice with respect thereto
delivered pursuant to subsection (a)(ii) above, payable on the interest





                                      -20-
<PAGE>   27
payment date or dates specified by the Borrower for such B Advance in the
related Notice of B Borrowing delivered pursuant to subsection (a)(i) above, as
provided in the B Note evidencing such B Advance.

       (f)    The indebtedness of the Borrower resulting from each B Advance
made to the Borrower as part of a B Borrowing shall be evidenced by a separate
B Note of the Borrower payable to the order of the Bank making such B Advance.

       Section 2.09.  Payments, Computations; Interest on Overdue Amounts.

       (a) The Borrower shall make each payment hereunder and under the Notes
to be made by it not later than 10:00 A.M. (Dallas time) on the day when due in
U.S. dollars to the Agent at its address referred to in Section 10.02 in same
day funds.  The Agent will promptly thereafter cause to be distributed like
funds relating to the payment of principal, interest or fees ratably (other
than amounts payable pursuant to Section 2.06(c), 2.08, 2.10, 2.11 or 2.13) to
the Banks for the account of their respective Applicable Lending Offices, and
like funds relating to the payment of any other amount payable to any Bank to
such Bank for the account of its Applicable Lending Office, in each case to be
applied in accordance with the terms of this Agreement.  In no event shall any
Bank be entitled to share any administrative fee paid to the Agent pursuant to
Section 2.03(b), any bid request fee paid to the Agent pursuant to Section
2.03(c) or any other fee paid to the Agent, as such.

       (b)    All computations of interest based on the Base Rate and of fees
shall be made by the Agent on the basis of a year of 365 or 366 days, as the
case may be, and all computations of interest based on the Eurodollar Rate or
the Federal Funds Rate shall be made by the Agent, and all computations of
interest pursuant to Section 2.06(c) shall be made by a Bank, on the basis of a
year of 360 days, in each case for the actual number of days (including the
first day but excluding the last day) occurring in the period for which such
interest or fees are payable.  Each determination by the Agent (or, in the case
of Section 2.06(c), by a Bank) of an interest rate hereunder shall be
conclusive and binding for all purposes, absent manifest error.

       (c)    Whenever any payment hereunder or under the Notes shall be stated
to be due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or fee, as the case may be;
provided, however, if such extension would cause payment of interest on or
principal of Eurodollar Rate Advances to be made in the next following calendar
month, such payment shall be made on the next preceding Business Day.

       (d)    Unless the Agent shall have received notice from the Borrower
prior to the date on which any payment is due by the Borrower to any Bank
hereunder that the Borrower will not make such payment in full, the Agent may
assume that the Borrower has made such payment in full to the Agent on such
date and the Agent may, in reliance upon such assumption, cause to be
distributed to each Bank on such due date an amount equal to the amount then
due such Bank.  If and to the extent the Borrower shall not have so made such
payment in full to the Agent, each Bank shall repay





                                      -21-
<PAGE>   28
to the Agent forthwith on demand such amount distributed to such Bank together
with interest thereon, for each day from the date such amount is distributed to
such Bank until the date such Bank repays such amount to the Agent, at the
Federal Funds Rate.

       (e)    Whenever any reference is made to any Bank's "ratable share" or
"ratable portion" (or any similar reference) of any amount hereunder, such
share or portion shall be calculated to not more than four decimal places,
rounding up or down, as appropriate.

       (f)    Any amount payable hereunder or under the Notes or under any
other Credit Document which is not paid when due (whether at stated maturity,
by acceleration or otherwise) shall bear interest, to the extent permitted by
law, from the date on which such amount became due until such amount is paid in
full, payable on demand, at a rate per annum equal at all times to:  (i) in the
case of any overdue principal of any Advance, the greater of (x) the sum of the
Base Rate in effect from time to time plus 2% per annum and (y) the sum of the
rate per annum required to be paid on such Advance immediately prior to the
date on which such amount became due plus 2% per annum, or (ii) in the case of
any interest, fee or other amount payable hereunder or under the Notes or under
any other Credit Document, the sum of the Base Rate in effect from time to time
plus 2% per annum.

       Section 2.10.  Consequential Losses.  If (a) any payment (or purchase
pursuant to Section 2.11(c)) of principal of any Eurodollar Rate Advance or B
Advance made to the Borrower is made other than on the last day of an Interest
Period relating to such Advance (or in the case of a B Advance, other than on
the original scheduled maturity date thereof), as a result of a prepayment
pursuant to Section 2.05(b) or 2.12 or acceleration of the maturity of the
Notes pursuant to Section 2.15 or Section 8.01 or for any other reason or as a
result of any such purchase; or (b) the Borrower fails to make a principal or
interest payment with respect to any Eurodollar Rate Advance or B Advance on
the date such payment is due and payable, the Borrower shall, upon demand by
any Bank (with a copy of such demand to the Agent), pay to the Agent for the
account of such Bank any amounts required to compensate such Bank for any
additional losses, costs or expenses which it may reasonably incur as a result
of any such payment or purchase, including, without limitation, any loss
(including loss of reasonably anticipated profits, except in the case of such a
purchase pursuant to Section 2.11(c)), cost or expense incurred by reason of
the liquidation or reemployment of deposits or other funds acquired by such
Bank to fund or maintain such Advance.

       Section 2.11.  Increased Costs.

       (a) If, due to either (i) the introduction of or any change (including
without limitation, but without duplication, any change by way of imposition or
increase of reserve requirements included, in the case of Eurodollar Rate
Advances, the Eurodollar Rate Reserve Percentage) in or in the interpretation,
application or applicability of any law or regulation or (ii) the compliance
with any guideline or request from any central bank or other governmental
authority (whether or not having the force of law), there shall be any increase
in the cost to any Bank of agreeing to make or making, funding or maintaining
any Fixed Rate Advance to the Borrower, then the Borrower shall from time





                                      -22-
<PAGE>   29
to time, upon demand by such Bank (with a copy of such demand to the Agent),
pay to the Agent for the account of such Bank additional amounts sufficient to
compensate such Bank for such increased cost.  A certificate as to the amount
of such increased cost, submitted to the Borrower and the Agent by such Bank,
shall be prima facie evidence of the amount of such increased cost.  Promptly
after any Bank becomes aware of any such introduction, change or proposed
compliance, such Bank shall notify the Borrower thereof, provided that the
failure to provide such notice shall not affect such Bank's rights hereunder,
except that such Bank's right to recover such increased costs from the Borrower
for any period prior to such notice shall be limited to the period of (i) 180
days, if such increased cost relates to any outstanding Advance, or (ii) 90
days, in each other event, immediately prior to the date such notice is given
to the Borrower.

       (b)    If any Bank determines that compliance with any law or regulation
or any guideline or request from any central bank or other governmental
authority (whether or not having the force of law) affects or would affect the
amount of capital required or expected to be maintained by such Bank or any
corporation controlling such Bank and that the amount of such capital is
increased by or based upon the existence of such Bank's commitment to lend to
the Borrower hereunder and other commitments of this type, then, upon demand by
such Bank (with a copy of such demand to the Agent), the Borrower shall
immediately pay to the Agent for the account of such Bank, from time to time as
specified by such Bank, additional amounts sufficient to compensate such Bank
or such corporation in the light of such circumstances, to the extent that such
Bank reasonably determines such increase in capital to be allocable to the
existence of such Bank's commitment to lend hereunder.  A certificate as to
such amounts submitted to the Borrower and the Agent by such Bank shall be
conclusive and binding for all purposes, absent manifest error.

       (c)    In the event that any Bank makes a demand for payment under
Section 2.06(c) or this Section 2.11, the Borrower may within ninety days of
such demand, if no Default then exists, replace such Bank with another
commercial bank in accordance with all of the provisions of the last sentence
of Section 10.06(a) (including execution of an appropriate Assignment) provided
that (i) all obligations of such Bank to lend hereunder shall be terminated and
the A Note and any B Note payable to such Bank and all other obligations owed
to such Bank hereunder shall be purchased in full without recourse at par plus
accrued interest at or prior to such replacement, (ii) such replacement bank
shall be reasonably satisfactory to the Agent, (iii) such replacement bank
shall, from and after such replacement, be deemed for all purposes to be a
"Bank" hereunder with a Commitment in the amount of the respective Commitment
of the assigning Bank immediately prior to such replacement (plus, if such
replacement bank is already a Bank prior to such replacement, the respective
Commitment of such Bank prior to such replacement), as such amount may be
changed from time to time pursuant hereto, and shall have all of the rights,
duties and obligations hereunder of the Bank being replaced, and (iv) such
other actions shall be taken by the Borrower, such Bank and such replacement
bank as may be appropriate to effect the replacement of such Bank with such
replacement bank on terms such that such replacement bank has all of the
rights, duties and obligations hereunder as such Bank (including, without
limitation, execution and delivery of new Notes to such replacement bank,
redelivery to the Borrower in due course of the Notes payable to





                                      -23-
<PAGE>   30
such Bank and specification of the information contemplated by Schedule I as to
such replacement bank).

       Section 2.12.  Illegality.  Notwithstanding any other provision of this
Agreement, if any Bank shall notify the Agent that the introduction of or any
change in or in the interpretation of any law or regulation shall make it
unlawful, or any central bank or other governmental authority shall assert that
it is unlawful, for any Bank or its Applicable Lending Office to make any Fixed
Rate Advance or to continue to fund or maintain any Fixed Rate Advance
hereunder, then, on notice thereof to the Borrower by the Agent, (i) the
obligation of each of the Banks to make any Fixed Rate Advance of the same Type
shall be suspended until the Agent shall notify the Borrower and the Banks that
the circumstances causing such suspension no longer exist, and (ii) the
Borrower shall forthwith prepay in full all Fixed Rate Advances then
outstanding of all Banks which are affected Fixed Rate Advances, together with
all accrued interest thereon and all amounts payable pursuant to Section 2.10,
unless each Bank shall determine in good faith in its sole opinion that it is
lawful to maintain the Fixed Rate Advances made by such Bank to the end of the
Interest Period then applicable thereto.

       Section 2.13.  Taxes.

       (a) Any and all payments by the Borrower or the Guarantor hereunder or
under the Notes or any other Credit Document shall be made, in accordance with
Section 2.09, free and clear of and without deduction for any and all present
or future taxes, levies, imposts, deductions, charges or withholdings with
respect thereto, and all liabilities with respect thereto, excluding in the
case of each Bank and the Agent, taxes imposed on its income, and franchise
taxes imposed on it, by the jurisdiction under the laws of which such Bank or
the Agent (as the case may be) is organized or any political subdivision
thereof and, in the case of each Bank, taxes imposed on its income, and
franchise taxes imposed on it, by the jurisdiction of such Bank's Applicable
Lending Office or any political subdivision thereof (all such non-excluded
taxes, levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes").  If the Borrower or the Guarantor shall be
required by law to deduct any Taxes from or in respect of any sum payable by it
hereunder or under any Note or other Credit Document to any Bank or the Agent,
(i) the sum payable shall be increased as may be necessary so that after making
all required deductions (including deductions applicable to additional sums
payable under this Section 2.13) such Bank or the Agent (as the case may be)
receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower or the Guarantor, as the case may be,
shall make such deductions and (iii) the Borrower or the Guarantor, as the case
may be, shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law.

       (b)    In addition, the Borrower or the Guarantor, as the case may be,
agrees to pay any present or future stamp or documentary taxes or any other
excise or property taxes, charges or similar levies which arise from any
payment made by the Borrower or the Guarantor hereunder or under any Note or
other Credit Document executed by it or from the execution, delivery or





                                      -24-
<PAGE>   31
registration of, or otherwise with respect to, this Agreement or any Note or
other Credit Document (hereinafter referred to as "Other Taxes").

       (c)    THE BORROWER AND THE GUARANTOR WILL INDEMNIFY EACH BANK, EACH CO-
AGENT, THE ARRANGER & SYNDICATION AGENT AND THE AGENT FOR THE FULL AMOUNT OF
TAXES OR OTHER TAXES (INCLUDING, WITHOUT LIMITATION, ANY TAXES OR OTHER TAXES
IMPOSED BY ANY JURISDICTION ON AMOUNTS PAYABLE UNDER THIS SECTION 2.13) OWED
AND PAID BY SUCH BANK, SUCH CO-AGENT, THE ARRANGER & SYNDICATION AGENT OR THE
AGENT (AS THE CASE MAY BE) AND ANY LIABILITY (INCLUDING PENALTIES, INTEREST AND
EXPENSES) ARISING THEREFROM OR WITH RESPECT THERETO.  THIS INDEMNIFICATION
SHALL BE MADE WITHIN 30 DAYS FROM THE DATE SUCH BANK, SUCH CO-AGENT, THE
ARRANGER & SYNDICATION AGENT OR THE AGENT (AS THE CASE MAY BE) MAKES WRITTEN
DEMAND THEREFOR.

       (d)    Within 30 days after the date of the payment of Taxes by or at
the direction of the Borrower or the Guarantor, the Borrower will furnish to
the Agent, at its address referred to in Section 10.02, the original or a
certified copy of a receipt evidencing payment thereof.

       (e)    Without prejudice to the survival of any other agreement of the
Borrower or the Guarantor hereunder, the agreements and obligations of the
Borrower and the Guarantor contained in this Section 2.13 shall survive the
payment in full of principal and interest hereunder and under the Notes and
other Credit Documents.

       (f)    Each Bank that is not incorporated under the laws of the United
States of America or a state thereof agrees that it will deliver to the
Borrower and the Agent on the date of this Agreement or upon the effectiveness
of any Assignment and Acceptance (i) two duly completed copies of United States
Internal Revenue Service Form 1001 or 4224 or successor applicable form, as the
case may be, certifying in each case that such Bank is entitled to receive
payments under this Agreement and the Notes payable to it, without deduction or
withholding of any United States federal income taxes, (ii) if applicable, an
Internal Revenue Service Form W-8 or W-9 or successor applicable form, as the
case may be, to establish an exemption from United States backup withholding
tax, and (iii) any other governmental forms which are necessary or required
under an applicable tax treaty or otherwise by law to reduce or eliminate any
withholding tax, which have been reasonably requested by the Borrower.  Each
Bank which delivers to the Borrower and the Agent a Form 1001 or 4224 and Form
W-8 or W-9 pursuant to the next preceding sentence further undertakes to
deliver to the Borrower and the Agent two further copies of the said Form 1001
or 4224 and Form W-8 or W-9, or successor applicable forms, or other manner of
certification, as the case may be, on or before the date that any such form
expires or becomes obsolete or after the occurrence of any event requiring a
change in the most recent form previously delivered by it to the Borrower and
the Agent, and such extensions or renewals thereof as may reasonably be
requested by the Borrower and the Agent certifying in the case of a Form 1001
or 4224 that such Bank is





                                      -25-
<PAGE>   32
entitled to receive payments under this Agreement without deduction or
withholding of any United States federal income taxes.  The Borrower shall
withhold tax at the rate and in the manner required by the laws of the United
States with respect to payments made to a Bank failing to timely provide the
requisite Internal Revenue Service forms.

       Section 2.14.  Payments Pro Rata.  Except as provided in Sections
2.03(b), 2.03(c), 2.03(d), 2.06(c), 2.10, 2.11, or 2.13, each of the Banks
agrees that if it should receive any payment (whether by voluntary payment, by
realization upon security, by the exercise of the right of setoff or banker's
lien, by counterclaim or cross action, by the enforcement of any right under
this Agreement or the Notes or other Credit Documents, or otherwise) in respect
of any obligation of the Borrower or Guarantor hereunder or under the Notes or
other Credit Documents of a sum which with respect to the related sum or sums
received by other Banks is in a greater proportion than the total amount of
principal, interest, fees or any other obligation incurred hereunder, as the
case may be, then owed and due to such Bank bears to the total amount of
principal, interest, fees or any such other obligation then owed and due to all
of the Banks immediately prior to such receipt, then such Bank receiving such
excess payment shall purchase for cash without recourse from the other Banks an
interest in the obligations of the Borrower to such Banks in such amount as
shall result in a proportional participation by all of the Banks in the
aggregate unpaid amount of principal, interest, fees or any such other
obligation, as the case may be, owed to all of the Banks, provided that if all
or any portion of such excess payment is thereafter recovered from such
purchasing Bank, such purchase from each other Bank shall be rescinded and each
such other Bank shall repay to the purchasing Bank the purchase price to the
extent of such other Bank's ratable share (according to the proportion of (i)
the amount of the participation purchased from such other Bank as a result of
such excess payment to (ii) the total amount of such excess payment) of such
recovery together with an amount equal to such other Bank's ratable share
(according to the proportion of (i) the amount of such other Bank's required
repayment to (ii) the total amount so recovered from the purchasing Bank) of
any interest or other amount paid or payable by the purchasing Bank in respect
of the total amount so recovered.  The Borrower agrees that any Bank so
purchasing a participation from another Bank pursuant to this Section 2.14 may,
to the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off) with respect to such participation as fully as
if such Bank were the direct creditor of the Borrower in the amount of such
participation.

       Section 2.15. Increase of Aggregate Commitments.  Provided no Default
has occurred and is continuing, the Borrower may by written notice to the Agent
and the Banks request that the aggregate amount of the Commitments hereunder be
increased up to the Aggregate Commitment Limit; provided, however that in the
event the Parallel Agreement is still in effect, (a) the Borrower shall
simultaneously request a pro rata increase in the  aggregate amount of the
Parallel Agreement Commitments pursuant to Section 2.15 of the Parallel
Agreement, and (b) after giving effect to such increase of the aggregate
Commitments and such pro rata increase of the aggregate Parallel Agreement
Commitments, the total amount of all Commitments and all Parallel Agreement
Commitments shall not exceed the Aggregate Commitment Limit.  Upon the
Borrower's receipt of (a) incremental commitments from such Banks that may
agree to provide an increased Commitment hereunder, and if the Parallel
Agreement is still in effect, an increased Parallel Agreement





                                      -26-
<PAGE>   33
Commitment under the Parallel Agreement (there being no obligation on the part
of any Bank at any time hereunder to increase such Bank's Commitment or such
Bank's Parallel Agreement Commitment but any such increase agreed upon by any
Bank to be pro rata between this Agreement and the Parallel Agreement so that
its ratable percentage of each is the same) and/or (b) commitments from new
lenders willing to become a Bank with a Commitment hereunder, and if the
Parallel Agreement is still in effect, a "Bank" under the Parallel Agreement
with a pro rata Parallel Agreement Commitment, then such increase of the
aggregate Commitments shall become effective simultaneously with any such
increase of the aggregate Parallel Agreement Commitments when the following
conditions precedent and, if applicable,  the conditions precedent set forth in
Section 2.15 of the Parallel Agreement have been satisfied and the Agent shall
have notified the parties hereto to such effect:

       (i)    The Borrower shall have delivered to the Agent, with sufficient
copies for each Bank (A) a certificate of the Chief Financial Officer of the
Borrower addressed to the Banks to the effect that, to the best of such
officer's knowledge, (x) no Default or Event of Default has occurred and is
continuing (or would result from the incurrence of the additional Debt
contemplated by this Section 2.15), and (y) all representations and warranties
herein or in any other Credit Document are true and correct in all material
respects with the same effect as if these representations and warranties had
been made on the date of such certificate (it being understood and agreed that
any representation which by its terms is made as of a specified date shall be
required to be true and correct in all material respects only as of such
specified date), and (B) unless the documentation delivered in connection with
the effectiveness of this Agreement otherwise authorizes Debt hereunder and
under the Parallel Agreement in an aggregate amount up to the Aggregate
Commitment Limit, a certificate of the Borrower's Secretary certifying that the
Borrower has been duly authorized by resolution of the Borrower's Board of
Directors to incur Debt hereunder and, if the Parallel Agreement is still in
effect, under the Parallel Agreement in an amount equal to or exceeding the
increased aggregate amount of the Commitments and, if the Parallel Agreement is
still in effect, the Parallel Agreement Commitments.

       (ii)   An Accession Agreement for each New Bank shall have been duly
executed by each party thereto.

       (iii)  The Agent has received the written consent of each Bank which has
agreed to increase  its Commitment hereunder (but no other Bank's consent shall
be required), such consent to be substantially in the form of the Consent to
Increase of Commitment attached as Exhibit G.

       (iv)   New Notes (including without limitation substitute Notes for
those Banks which have agreed to increase their respective Commitments) shall
have been executed and delivered by the Borrower in substantially the form of
Exhibits A-1 and A-2, as appropriate.

       (v)    No A Advances are outstanding hereunder as of the date such
increase is to become effective, or any such Advances are contemporaneously
repaid on such date.

that on the date of such A Borrowing the following statements shall be true

each case be subject to the further condition precedent that on the date of
such Borrowing, no Default occurred and is continuing, or would result from

and the Agent shall have received such other approvals, opinions or documents

                                   ARTICLE IV

                                    GUARANTY

       Section 4.01.  Guaranty.  The Guarantor hereby unconditionally
guarantees the punctual payment of the Guaranteed Obligations when due, whether
at stated maturity, by acceleration or otherwise, and agrees to pay any and all
expenses (including counsel fees and expenses) incurred by the Agent or any
Bank in enforcing any rights hereunder.  Without limiting the generality of the
foregoing, the Guarantor's liability shall extend to all amounts which
constitute part of the Guaranteed Obligations and would be owed by the Borrower
under this Agreement or any of the Notes but for the fact that the claims to
such amounts are, or are deemed to be, stayed, unenforceable, not allowable,
discharged, or otherwise reduced, restricted or limited in any manner due to
the existence of a bankruptcy, reorganization or similar proceeding involving
the Borrower.

       Section 4.02.  Guaranty Absolute.  The Guarantor guarantees that the
Guaranteed Obligations will be paid strictly in accordance with the terms of
the Credit Documents executed from time to time by the Borrower, regardless of
any law, regulation or order now or hereafter in effect in any jurisdiction
affecting any of such terms or the rights of the Agent or any Bank with respect
thereto.  The obligations of the Guarantor hereunder are independent of the
Guaranteed Obligations, and provided an Event of Default exists as to the
Borrower and is continuing at the time an action is brought, a separate action
or actions may be brought and prosecuted against the Guarantor to enforce this
Agreement, irrespective or whether any action is brought against the Borrower
or whether the Borrower is joined in any such action or actions.  The liability
of the Guarantor hereunder shall be absolute and unconditional irrespective of:

              (i)    any lack of validity or enforceability of any of the
       Credit Documents against the Borrower;

              (ii)   any change in the time, manner or place of payment of, or
       in any other term of, all or any of the Guaranteed Obligations or any
       other liabilities, or any other amendment or waiver of or any consent to
       departure from any of the Credit Documents, including, without
       limitation, any increase in the Guaranteed Obligations or any other
       liabilities resulting from the making of additional Advances guaranteed
       by the Guarantor to the Borrower or otherwise;

              (iii)  any taking, exchange, release or non-perfection of any
       collateral, or any taking, release or amendment or waiver of or consent
       to departure from any other guaranty, for all or any of the Guaranteed
       Obligations or any other liabilities;





                                      -31-
<PAGE>   38
              (iv)   any manner of application of collateral, or proceeds
       thereof, to all or any of the Guaranteed Obligations or any other
       liabilities, or any manner of sale or other disposition of any
       collateral for all or any of the Guaranteed Obligations or any other
       liabilities or any other assets of the Borrower or any of its
       Subsidiaries;

              (v)    any change, restructuring or termination of the corporate
       structure or existence of the Borrower or any of its Subsidiaries; or

              (vi)   any other circumstances which might otherwise constitute a
       defense available to, or a discharge of, the Borrower or a guarantor.

       This guaranty shall continue to be effective or be reinstated, as the
case may be, if at any time any payment of any of the Guaranteed Obligations is

30 consecutive days during which a stay of enforcement of such judgments or
orders, by reason of a pending appeal or otherwise, shall not be in effect; or

         THE AGENT, THE CO-AGENTS, AND THE ARRANGER & SYNDICATION AGENT

       Section 9.01.  Authorization and Action.  Each Bank hereby appoints and
authorizes the Agent to take such action as agent on its behalf and to exercise
such powers under the Credit Documents as are delegated to the Agent by the
terms hereof and thereof, together with such powers as are reasonably
incidental thereto.  As to any matters not expressly provided for by the Credit
Documents (including, without limitation, enforcement or collection of the
Notes), the Agent shall not be required to exercise any discretion or take any
action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions
of the Majority Banks, and such instructions shall be binding upon all Banks
and all holders of Notes; provided, however, that the Agent shall not be
required to take any action which exposes the Agent to personal liability or
which is contrary to any Credit Document or applicable law.  The Agent agrees
to give to each Bank prompt notice of each notice given to it by the Borrower
pursuant to the terms of this Agreement.

       Section 9.02.  Agent's Reliance, Etc.  Neither the Agent nor any of its
directors, officers, agents or employees shall be liable for any action taken
or omitted to be taken by it or them under or in connection with the Credit
Documents, except for its or their own gross negligence or willful misconduct.
Without limitation of the generality of the foregoing, the Agent:  (i) may
treat the payee of any Note as the holder thereof until the Agent receives and
accepts an Assignment executed by the Borrower, the Bank which is the payee of
such Note, as assignor, and the assignee in accordance with Section 10.06; (ii)
may consult with legal counsel (including counsel for the Borrower),
independent public accountants and other experts selected by it and shall not
be liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants or experts; (iii) makes
no warranty or representation to any Bank and shall not be responsible to any
Bank for any statements, warranties or representations made in or in connection
with the Credit Documents; (iv) shall not have any duty to ascertain or to
inquire as to the performance or observance of any of the terms, covenants or
conditions of the Credit Documents on the part of the Borrower or the Guarantor
or to inspect the property (including the books and records) of the Borrower or
the Guarantor; (v) shall not be responsible to any Bank for the due execution,
legality, validity, enforceability, genuineness, sufficiency or value of the
Credit Documents; and (vi) shall incur no liability under or in respect of the
Credit Documents by acting upon any notice, consent, certificate or other
instrument or writing (which may be by telecopier, telegram, cable or telex)
believed by it to be genuine and signed or sent by the proper party or parties.

       Section 9.03.  NationsBank and Affiliates.  With respect to its
Commitment, the Advances made by it and the Notes issued to it, NationsBank
shall have the same rights and powers under the Credit Documents and any Note
payable to NationsBank as any other Bank and may exercise the same as though it
was not the Agent; and the term "Bank" or "Banks" shall, unless otherwise





                                      -46-
<PAGE>   53
expressly indicated, include NationsBank in its individual capacity.
NationsBank and its affiliates may accept deposits from, lend money to, act as
trustee under indentures of, and generally engage in any kind of business with,
the Borrower, the Guarantor, any Subsidiary of the Borrower or the Guarantor
and any Person who may do business with or own securities of the Borrower, the
Guarantor, or any such Subsidiary, all as if NationsBank were not the Agent and
without any duty to account therefor to the Banks.

       Section 9.04.  Bank Credit Decision.  Each Bank acknowledges that it
has, independently and without reliance upon the Agent, the Arranger &
Syndication Agent or any other Bank and based on the financial statements
referred to in Section 5.05 and such other documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into
this Agreement.  Each Bank also acknowledges that it will, independently and
without reliance upon the Agent, the Arranger & Syndication Agent or any other
Bank and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under the Credit Documents.

       SECTION 9.05.  INDEMNIFICATION.  THE BANKS AGREE TO INDEMNIFY THE AGENT,
EACH CO-AGENT, AND THE ARRANGER & SYNDICATION AGENT (TO THE EXTENT NOT
REIMBURSED BY THE BORROWER OR THE GUARANTOR), RATABLY ACCORDING TO THE
RESPECTIVE PRINCIPAL AMOUNTS OF THE A NOTES THEN HELD BY EACH OF THEM (OR IF NO
A NOTES ARE AT THE TIME OUTSTANDING OR IF ANY A NOTES ARE HELD BY PERSONS WHICH
ARE NOT BANKS, RATABLY ACCORDING TO EITHER (I) THE RESPECTIVE AMOUNTS OF THEIR
COMMITMENTS, OR (II) IF ALL COMMITMENTS HAVE TERMINATED, THE RESPECTIVE AMOUNTS
OF THE COMMITMENTS IMMEDIATELY PRIOR TO THE TIME THE COMMITMENTS TERMINATED),
FROM AND AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES,
PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS OF ANY
KIND OR NATURE WHATSOEVER WHICH MAY BE IMPOSED ON, INCURRED BY, OR ASSERTED
AGAINST THE AGENT, SUCH CO-AGENT OR THE ARRANGER & SYNDICATION AGENT IN ANY WAY
RELATING TO OR ARISING OUT OF THE CREDIT DOCUMENTS OR ANY ACTION TAKEN OR
OMITTED BY THE AGENT UNDER THE CREDIT DOCUMENTS, PROVIDED THAT NO BANK SHALL BE
LIABLE TO THE AGENT, SUCH CO-AGENT OR THE ARRANGER & SYNDICATION AGENT FOR ANY
PORTION OF SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS,
JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING FROM THE AGENT'S,
SUCH CO-AGENT'S OR THE ARRANGER & SYNDICATION AGENT'S GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT.  WITHOUT LIMITATION OF THE FOREGOING, EACH BANK AGREES TO
REIMBURSE THE AGENT PROMPTLY UPON DEMAND FOR ITS RATABLE SHARE OF ANY
OUT-OF-POCKET EXPENSES (INCLUDING COUNSEL





                                      -47-
<PAGE>   54
FEES) INCURRED BY THE AGENT IN CONNECTION WITH THE PREPARATION, EXECUTION,
DELIVERY, ADMINISTRATION, MODIFICATION, AMENDMENT OR ENFORCEMENT (WHETHER
THROUGH NEGOTIATIONS, LEGAL PROCEEDINGS OR OTHERWISE) OF, OR LEGAL ADVICE IN
RESPECT OF RIGHTS OR RESPONSIBILITIES UNDER, THE CREDIT DOCUMENTS TO THE EXTENT
THAT THE AGENT IS NOT REIMBURSED FOR SUCH EXPENSES BY THE BORROWER OR THE
GUARANTOR.

       Section 9.06.  Successor Agent.  The Agent may resign at any time as
Agent under this Agreement by giving written notice thereof to the Banks and
the Borrower and may be removed at any time by the Borrower if at any time the
Agent, in its individual capacity as a Bank hereunder, shall hold less than
$30,000,000 of the aggregate Commitments.  Upon any such resignation or
removal, the Borrower shall have the right to appoint, with the consent of the
Majority Banks (which consent shall not be unreasonably withheld), a successor
Agent.  If no successor Agent shall have been so appointed by the Borrower with
such consent of the Majority Banks, and shall have accepted such appointment,
within 30 days after the retiring Agent's giving of notice of resignation or
the Borrower's removal of the retiring Agent, then the retiring Agent may, on
behalf of the Banks, appoint a successor Agent, which shall be a Bank which is
a commercial bank organized under the laws of the United States of America or
of any State thereof and having a combined capital and surplus of at least
$500,000,000.  Upon the acceptance of any appointment as Agent under this
Agreement by a successor Agent, such successor Agent shall thereupon succeed to
and become vested with all the rights, powers, privileges and duties of the
retiring Agent and shall function as the Agent under this Agreement, and the
retiring Agent shall be discharged from its duties and obligations as Agent
under this Agreement.  After any retiring Agent's resignation or removal
hereunder as Agent, the provisions of this Article IX shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent
under this Agreement.

       Section 9.07.  Co-Agents; Arranger & Syndication Agent.  The Co-Agents
and the Arranger & Syndication Agent shall have no duties, obligations, or
liabilities in their capacities as such.

provision of any Credit Document, nor consent to any departure by the Borrower
or the Guarantor therefrom, shall in any event be effective unless the same
shall be in writing and signed by the Borrower and the Majority Banks, and then
such waiver or consent shall be effective only in the specific instance and for
the specific purpose for which given; provided, however, that no amendment,
waiver or consent shall, unless in writing and signed by all the Banks, do any
of the following:  (a) waive any of the

to pay any amount payable by the Guarantor hereunder or (h) amend this Section
10.01; provided, further, that no amendment, waiver or consent shall, unless in
writing and signed by the Agent in addition to the Banks required above to take
such action, affect the rights or duties of the Agent under any Credit
Document; and provided, further, that no amendment, waiver or consent shall,
unless in writing and signed by the Guarantor in addition to any other party
required above to take such action, affect the rights or duties of the
Guarantor under any Credit Document; and provided, further, that no increase
may be made with respect to any Bank's Commitment without the consent of such
Bank.

       Section 10.02.  Notices, Etc.  All notices and other communications
provided for hereunder shall be in writing (including telecopy, telegraphic,

       Section 10.03.  No Waiver; Remedies.  No failure on the part of any Bank
or the Agent to exercise, and no delay in exercising, any right under any
Credit Document shall operate as a waiver thereof; nor shall any single or
partial exercise of any such right preclude any other or further exercise
thereof or the exercise of any other right.  The remedies provided in the
Credit Documents are cumulative and not exclusive of any remedies provided by
law.

unmatured.  Each Bank agrees promptly to notify the Borrower and the Guarantor
after such set-off and application made by such Bank, provided that the failure
to give such notice shall not affect the validity of such set-off and
application.  The rights of each Bank under this Section are in addition to
other rights and remedies (including, without limitation, other rights of
set-off) which such Bank may have.

       Section 10.06.  Bank Assignments and Participations.

       (a)    Assignments.  Any Bank may assign to one or more banks or other
entities all or any portion of its rights and obligations under this Agreement
(including, without limitation, all or a portion of its Commitment, the
Advances owing to it, and the Notes held by it); provided, however, that (i)
each such assignment of an Assigning Bank's Commitment shall be of a constant,
and not a varying, percentage of all of such Bank's rights and obligations
under this Agreement in respect of such Commitment and such Bank shall
simultaneously assign a pro rata portion of  such Bank's rights and obligations
in respect of its Parallel Agreement Commitment so that its pro rata percentage
of each of the Commitments and the Parallel Agreement Commitments is the same,
(ii) the amount of the resulting Commitment and Advances of the assigning Bank
(unless it is assigning all its Commitment and all of its Parallel Agreement
Commitment) and the assignee Bank pursuant to each such assignment (determined
as of the date of the Assignment with respect to such assignment) shall in no
event be less than $10,000,000 and shall be an integral multiple of $1,000,000,
(iii) each such assignment shall be to an Eligible Assignee, (iv) the parties
to each such assignment shall execute and deliver to the Agent, for its
acceptance and recording in the Register, an Assignment, together with the Note
or Notes subject to such assignment, and (v) each Eligible Assignee not already
a Bank hereunder shall pay to the Agent an assignment fee of $3000 in
connection with such assignment. Upon such execution, delivery, acceptance and
recording, from and after the effective date specified in each Assignment,
which effective date shall be at least three Business Days after the execution
thereof, (A) the assignee thereunder shall be a party hereto for all purposes
and, to the extent that rights and obligations hereunder have been assigned to
it pursuant to such Assignment, have the rights and obligations of a Bank
hereunder and (B) such Bank thereunder shall, to the extent that rights and
obligations hereunder have been assigned by it pursuant to such Assignment,
relinquish its rights and be released from its obligations under this Agreement
(and, in the case of an Assignment covering all or the remaining portion of
such Bank's rights and obligations under this Agreement, such Bank shall cease
to be a party hereto).

       (b)    Terms of Assignments.  By executing and delivering an Assignment,
the Bank thereunder and the assignee thereunder confirm to and agree with each
other and the other parties hereto the matters set forth in paragraphs 2 and 3
of such Assignment.





                                      -51-
<PAGE>   58
       (c)    The Register.  The Agent shall maintain at its address referred
to on Schedule I a copy of each Assignment delivered to and accepted by it and
a register for the recordation of the names and addresses of the Banks and the
Commitments of, and principal amount of the Advances owing to, each Bank from
time to time (the "Register").  The entries in the Register shall be conclusive
and binding for all purposes, absent manifest error, and the Borrower, the
Guarantor, the Agent, and the Banks may treat each Person whose name is
recorded in the Register as a Bank hereunder for all purposes of this
Agreement.  The Register shall be available for inspection by the Borrower, the
Guarantor, or any Bank at any reasonable time and from time to time upon
reasonable prior notice.

       (d)    Procedures.  Upon its receipt of an Assignment executed by a Bank
and an Eligible Assignee, together with the Note or Notes subject to such
assignment, the Agent shall, if such Assignment has been completed and is in
substantially the form of the attached Exhibit C, (i) accept such Assignment,
(ii) record the information contained therein in the Register, and (iii) give
prompt notice thereof to the Borrower and the Guarantor.  Within five Business
Days after its receipt of such notice, the Borrower, at its own expense, shall
execute and deliver to the Agent (x) in exchange for the surrendered A Note, a
new A Note to the order of such Eligible Assignee in an amount equal to the
Commitment assumed by it pursuant to such Assignment (without giving affect to
any B Reduction) and, if such assigning Bank has retained any Commitment
hereunder, a new A Note to the order of such Bank in an amount equal to the
Commitment retained by it hereunder (without giving affect to any B Reduction),
and (y) in exchange for any surrendered B Note, a new B Note to the order of
such Eligible Assignee in an amount equal to the B Advances assumed by it
pursuant to such Assignment and, if such assigning Bank has retained any B
Advances hereunder, a new B Note to the order of such Bank in any amount equal
to the B Advances retained by it hereunder.  Such new A Notes and B Notes shall
be dated the effective date of such Assignment and shall otherwise be in
substantially the form of the attached Exhibit A-1 or Exhibit A-2, as the case
may be.

       (e)    Participations.  Each Bank may sell participations to one or more
banks or other entities in or to all or a portion of its rights and obligations
under this Agreement (including, without limitation, all or a portion of its
Commitment, the Advances owing to it, and the Notes held by it); provided,
however, that (i) such Bank's obligations under this Agreement (including,
without limitation, its Commitment to the Borrower hereunder) shall remain
unchanged, (ii) such Bank shall remain solely responsible to the other parties
hereto for the performance of such obligations, (iii) such Bank shall remain
the holder of any such Notes for all purposes of this Agreement, (iv) the
Borrower, the Guarantor, the Agent, and the other Banks shall continue to deal
solely and directly with such Bank in connection with such Bank's rights and
obligations under this Agreement, (v) such Bank shall not require the
participant's consent to any matter under this Agreement, except for changes in
the principal amount of such Bank's Commitment, any Note payable to such Bank
in which the participant has an interest, or the aggregate Commitments,
reductions in fees or interest, the date any amount is due hereunder, or
extending the Termination Date or continuing the Commitment of such Bank
pursuant to Section 2.15 hereof, and (vi) such Bank shall give prompt





                                      -52-
<PAGE>   59
notice to the Borrower of each such participation sold by such Bank.  The
Borrower hereby agrees that participants shall have the same rights under
Sections 2.06(c), 2.10, 2.11, and 10.04 hereof as the Bank to the extent of
their respective participations.

       (f)  Assignment to Federal Reserve Bank.  Notwithstanding the
limitations set forth in paragraph (a) of this Section, any Bank may at any
time assign all or any portion of its rights under this Agreement or any Notes
payable to such Bank to a Federal Reserve Bank without the prior written
consent of the Borrower, the Guarantor, the Agent, the Co-Agents, or the
Arranger & Syndication Agent, provided that no such assignment shall release
such assigning Bank from any of its obligations hereunder or substitute any
such Federal Reserve Bank for such Bank as a party hereto.

       Section 10.07.  Governing Law.  This Agreement, the Notes and the other
Credit Documents shall be governed by, and construed in accordance with, the
laws of the State of Texas.

       Section 10.08.  Interest.

       (a)    It is the intention of the parties hereto that the Agent and each
Bank shall conform strictly to usury laws applicable to it, if any.
Accordingly, if the transactions with the Agent or any Bank contemplated hereby
would be usurious under applicable law, if any, then, in that event,
notwithstanding anything to the contrary in this Agreement, the Notes, or any
other agreement entered into in connection with or as security for this
Agreement or the Notes, it is agreed as follows:  (i) the aggregate of all
consideration which constitutes interest under applicable law that is
contracted for, taken, reserved, charged or received by the Agent or such Bank,
as the case may be, under this Agreement, the Notes, or under any other
agreement entered into in connection with or as security for this Agreement or
the Notes shall under no circumstances exceed the maximum amount allowed by
such applicable law and any excess shall be cancelled automatically and, if
theretofore paid, shall at the option of the Agent or such Bank, as the case
may be, be credited by the Agent or such Bank, as the case may be, on the
principal amount of the obligations owed to the Agent or such Bank, as the case
may be, by the Borrower or refunded by the Agent or such Bank, as the case may
be, to the Borrower, and (ii) in the event that the maturity of any Note or
other obligation payable to the Agent or such Bank, as the case may be, is
accelerated or in the event of any required or permitted prepayment, then such
consideration that constitutes interest under law applicable to the Agent or
such Bank, as the case may be, may never include more than the maximum amount
allowed by such applicable law and excess interest, if any, to the Agent or
such Bank, as the case may be, provided for in this Agreement or otherwise
shall be cancelled automatically as of the date of such acceleration or
prepayment and, if theretofore paid, shall, at the option of the Agent or such
Bank, as the case may be, be credited by the Agent or such Bank, as the case
may be, on the principal amount of the obligations owed to the Agent or such
Bank, as the case may be, by the Borrower or refunded by the Agent or such
Bank, as the case may be, to the Borrower.  To the extent that any Bank may be
subject to Texas law limiting the amount of interest





                                      -53-
<PAGE>   60
payable for its account, such Bank shall utilize the indicated (weekly) rate
ceiling from time to time in effect as provided in Article 5069-1.04 of the
Revised Civil Statutes of Texas, as amended.

       (b)    In the event that at any time the interest rate applicable to any
Advance made by any Bank would exceed the maximum non-usurious rate allowed by
applicable law, the rate of interest to accrue on the Advances by such Bank
shall be limited to the maximum non-usurious rate allowed by applicable law,
but shall accrue, to the extent permitted by law, on the principal amount of
the Advances made by such Bank from time to time outstanding, if any, at the
maximum non-usurious rate allowed by applicable law until the total amount of
interest accrued on the Advances made by such Bank equals the amount of
interest which would have accrued if the interest rates applicable to the
Advances pursuant to Article II had at all times been in effect.  In the event
that upon the final payment of the Advances made by any Bank and termination of
the Commitment of such Bank, the total amount of interest paid to such Bank
hereunder and under the Notes is less than the total amount of interest which
would have accrued if the interest rates applicable to such Advances pursuant
to Article II had at all times been in effect, then the Borrower agrees to pay
to such Bank, to the extent permitted by law, an amount equal to the excess of
(a) the lesser of (i) the amount of interest which would have accrued on such
Advances if the maximum non-usurious rate allowed by applicable law had at all
times been in effect or (ii) the amount of interest rates applicable to such
Advances pursuant to Article II had at all times been in effect over (b) the
amount of interest otherwise accrued on such Advances in accordance with this
Agreement.

       Section 10.09.  Execution in Counterparts.  This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.

       Section 10.10.  Survival of Agreements, Representations and Warranties,
Etc.  All warranties, representations and covenants made by the Borrower or the
Guarantor or any officer of the Borrower or the Guarantor herein or in any
certificate or other document delivered in connection with this Agreement shall
be considered to have been relied upon by the Banks and shall survive the
issuance and delivery of the Notes and the making of the Advances regardless of
any investigation.  Theindemnities and other obligations of the Borrower
contained in this Agreement, and the indemnities by the Banks in favor of the
Agent and its officers, directors, employees and agents, will survive the
repayment of the Advances and the termination of this Agreement.

       Section 10.11.  Borrower's Right to Apply Deposits.  In the event that
any Bank is placed in receivership or enters a similar proceeding, the Borrower
may, to the full extent permitted by law, make any payment due to such Bank
hereunder, to the extent of finally collected unrestricted deposits of the
Borrower in U.S. dollars held by such Bank, by giving notice to the Agent and
such Bank directing such Bank to apply such deposits to such indebtedness.  If
the amount of such





                                      -54-
<PAGE>   61
deposits is insufficient to pay such indebtedness then due and owing in full,
the Borrower shall pay the balance of such insufficiency in accordance with
this Agreement.

       Section 10.12.  Confidentiality.  Each Bank agrees that it will use best
efforts, to the extent not inconsistent with practical business requirements,
not to disclose without the prior consent of the Borrower and the Guarantor
(other than to employees, auditors, accountants, counsel or other professional
advisors of the Agent or any Bank or any Bank's Affiliate) any information with
respect to the Borrower or the Guarantor or their Subsidiaries which is
furnished pursuant to this Agreement and which (i) the Borrower or the
Guarantor in good faith consider to be confidential and (ii) is either clearly
marked confidential or is designated by the Borrower or the Guarantor to the
Agent or the Banks in writing as confidential, provided that any Bank may
disclose any such information (a) as has become generally available to the
public, (b) as may be required or appropriate in any report, statement or
testimony submitted to or required by any municipal, state or Federal
regulatory body having or claiming to have jurisdiction over such Bank or
submitted to or required by the Board of Governors of the Federal Reserve
System or the Federal Deposit Insurance Corporation or similar organizations
(whether in the United States or elsewhere) or their successors, (c) as may be
required or appropriate in response to any summons or subpoena in connection
with any litigation, (d) in order to comply with any law, order, regulation or
ruling applicable to such Bank, (e) to the prospective assignee or participant
in connection with any contemplated transfer of any of the Notes or any
interest therein by such Bank, provided that such prospective assignee or
participant executes an agreement with or for the benefit of the Borrower and
the Guarantor containing provisions substantially identical to those contained
in this Section 10.12.

       Section 10.13.  Binding Effect.  This Agreement shall become effective
when it shall have been executed by the Borrower, the Guarantor and the Agent,
and when each Bank listed on the signature pages hereof has delivered an
executed counterpart hereof to the Agent, has sent to the Agent a facsimile
copy of its signature hereon or has notified the Agent that such Bank has
executed this Agreement and thereafter shall be binding upon and inure to the
benefit of the Borrower, the Guarantor, the Agent, each Bank and their
respective successors and assigns, except that the Borrower and the Guarantor
shall not have the right to assign any of their respective rights hereunder or
any interest herein without the prior written consent of the Banks.

       SECTION 10.14.  ENTIRE AGREEMENT.  PURSUANT TO SECTION 26.02 OF THE
TEXAS BUSINESS AND COMMERCE CODE, A LOAN AGREEMENT IN WHICH THE AMOUNT INVOLVED
IN THE LOAN AGREEMENT EXCEEDS $50,000 IN VALUE IS NOT ENFORCEABLE UNLESS THE
LOAN AGREEMENT IS IN WRITING AND SIGNED BY THE PARTY TO BE BOUND OR THAT
PARTY'S AUTHORIZED REPRESENTATIVE.

       THE RIGHTS AND OBLIGATIONS OF THE PARTIES TO AN AGREEMENT SUBJECT TO THE
PRECEDING PARAGRAPH SHALL BE DETERMINED SOLELY





                                      -55-
<PAGE>   62
FROM THE WRITTEN LOAN AGREEMENT, AND ANY PRIOR ORAL AGREEMENTS BETWEEN THE
PARTIES ARE SUPERSEDED BY AND MERGED INTO THE LOAN AGREEMENT.  THIS WRITTEN
AGREEMENT AND THE CREDIT DOCUMENTS, AS DEFINED IN THIS AGREEMENT, REPRESENT THE
FINAL AGREEMENT AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF
PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

       Section 10.15.  Severability.  In the event that any one or more of the
provisions contained in this Agreement or in any other Credit Document should
be held invalid, illegal or unenforceable in any respect, the validity,
legality and enforceability of the remaining provisions contained herein and
therein shall not in any way be affected or impaired thereby.

"Credit Agreement"), among Fina Oil and Chemical Company, as borrower (the

thereto (the "Banks"), CIBC Inc. and Texas Commerce Bank National Association,
as Co-Agents, NationsBanc Capital Markets, Inc., as Arranger & Syndication
Agent, and NationsBank of Texas, N.A., as Agent for the Banks.  Terms defined
in the Credit Agreement are used herein as therein defined.

       [Opinion format of rendering counsel to be supplied by such counsel.]

                                   Opinions:

              i.            Each of the Borrower and the Guarantor is a
                     corporation duly organized, validly existing and in good
                     standing under the laws of the State of Delaware.

              ii.           Each of (i) the execution, delivery and performance
                     by each of the Borrower and the Guarantor of the Credit
                     Agreement, (ii) the execution, delivery and performance by
                     the Borrower of the A Notes and the other Notes to be
                     executed by the Borrower, and (iii) the consummation of
                     the transactions contemplated by the Credit Agreement, are
                     within the corporate powers of the Borrower and the
                     Guarantor, respectively, have been duly authorized by all
                     necessary corporate action, do not contravene (x) the
                     Certificate of Incorporation or the By-laws of the
                     Borrower or the Guarantor,





<PAGE>   83
                     respectively, or (y) any law, rule or regulation
                     applicable to the Borrower or the Guarantor (including,
                     without limitation, Regulation X of the Board of Governors
                     of the Federal Reserve System) or (z) any contractual or
                     legal restriction and will not result in or require the
                     creation or imposition of any Lien prohibited by the
                     Credit Agreement.  With respect to the Notes to be
                     executed after the date hereof by the Borrower, this
                     opinion is limited to laws, rules and regulations as in
                     force and applied on the date hereof, the Certificate of
                     Incorporation and the Bylaws of the Borrower, and
                     restrictions in effect on the date hereof.  The Credit
                     Agreement has been duly executed and delivered by the
                     Borrower and the Guarantor, and the A Notes have been duly
                     executed and delivered by the Borrower.

              iii.          No authorization, approval or other action by, and
                     no notice to or filing with, any governmental authority or
                     regulatory body is required for the due execution,
                     delivery and performance by the Borrower or the Guarantor
                     of the Credit Agreement, and (in the case of the Borrower)
                     the respective Notes or the consummation of the
                     transactions contemplated by the Credit Agreement.

              iv.           The A Notes executed by the Borrower constitute,
                     and each Note hereafter executed by the Borrower will
                     constitute, a legal, valid and binding obligation of the
                     Borrower, enforceable against the Borrower in accordance
                     with its terms.  The Credit Agreement executed by the
                     Borrower and the Guarantor constitutes legal, valid and
                     binding obligations of the Borrower and the Guarantor,
                     respectively, enforceable against the Borrower and the
                     Guarantor in accordance with its terms.

              v.            There are no pending or overtly threatened actions
                     or proceedings against the Borrower, the Guarantor or any
                     of their respective Subsidiaries before any court,
                     governmental agency or arbitrator which purport to affect
                     the legality, validity, binding effect or enforceability
                     of the Credit Agreement or any of the Notes or which could
                     reasonably be expected to have a materially adverse effect
                     upon the financial condition or operations of the Borrower
                     and its Subsidiaries taken as a whole, or the Guarantor
                     and its Subsidiaries taken as a whole.

              vi.           Neither the Borrower nor the Guarantor is an
                     "investment company" or a company "controlled" by an
                     "investment company" within the meaning of the Investment
                     Company Act of 1940, as amended.  Neither the Borrower nor
                     the Guarantor is a "holding company", or a "subsidiary
                     company" of a

                     "holding company", or an "affiliate" of a "holding

                  FORM OF OPINION OF SPECIAL COUNSEL TO AGENT





                               February 27, 1997


To each of the lenders parties
  to the Credit Agreement
  herein described and to
  NationsBank of Texas, N.A.,
  as Agent

Ladies and Gentlemen:

We have acted as special counsel to NationsBank of Texas, N.A., acting for
itself and as Agent, in connection with the preparation, execution and delivery
of the U.S.$100,000,000 364-Day Credit Agreement dated as of February 27, 1997
(the "Credit Agreement"), among Fina Oil and Chemical Company, as borrower (the
"Borrower"), Fina, Inc., as guarantor (the "Guarantor"), CIBC Inc. and Texas
Commerce Bank National Association, as Co-Agents, NationsBanc Capital Markets,
Inc., as Arranger & Syndication Agent, NationsBank of Texas, N.A., as agent
(the "Agent"), and each of you named as Banks thereunder.  Terms defined in the
Credit Agreement are used herein as therein defined.

In that connection, we have examined the following documents:

              (i)    counterparts of the Credit Agreement, executed by the
       Agent, the Borrower, and the Guarantor, respectively;

              (ii)   the A Notes dated as of February 27, 1997 of the Borrower
       payable to the order of each Bank party to the Credit Agreement as of
       the date hereof (the "A Notes"); and

              (iii)  the opinion dated February 27, 1997 of Cullen M. Godfrey,
       General Counsel for each of the Borrower and the Guarantor ("Opinion").

In our examination of the documents referred to above, we have assumed the
authenticity of all such documents submitted to us as originals, the
genuineness of all signatures and the conformity to the originals of all such
documents submitted to us as copies.  We have also assumed that each of the
Borrower, the Guarantor, the Banks and the Agent has duly executed and
delivered, with all necessary power and authority (corporate and otherwise),
the Credit Agreement, that the Borrower has duly executed and delivered, with
all necessary power and authority (corporate and otherwise),





<PAGE>   86

the A Notes.  We have also assumed that no Bank has requested that the Opinion
required by Section 3.01(d) of the Credit Agreement contain any other matters
not contained in the form of opinion set forth as Exhibit D to the Credit
Agreement.

Based upon the foregoing examination of documents and assumptions and upon such
other investigation as we have deemed necessary, we are of the opinion that the
A Notes and the Opinion, are substantially responsive to the requirements of
the Credit Agreement.

This opinion is solely for the benefit of the Banks, the Agent, their
respective successors, assigns, participants and other transferees and may be
relied upon only by such Persons.



                                        Very truly yours,



                                        Bracewell & Patterson, L.L.P.

              2.02(b)(iii), (iv), or (v));

       (ii)   the Borrower may not select Eurodollar Rate Advances for any A
              Borrowing to be made if the aggregate amount of such Borrowing is
              less than $20,000,000;

       (iii)  if any Bank shall, at least one Business Day before the date of
              any requested A Borrowing to be made, notify the Agent that the
              introduction of or any change in or in the interpretation of any
              law or regulation makes it unlawful, or that any central bank or
              other governmental authority asserts that it is unlawful, for
              such Bank or its Eurodollar Lending Office to perform its
              obligations hereunder to make Eurodollar Rate Advances or to fund
              Eurodollar Rate Advances hereunder, the right of the Borrower to
              select Eurodollar Rate Advances for such A Borrowing or any
              subsequent A Borrowing shall be suspended until such Bank shall
              notify the Agent that the circumstances causing such suspension
              no longer exist, and, except as provided in Section 2.02(b)(vi),
              each Advance comprising such A Borrowing shall be a Base Rate
              Advance;

       (iv)   if the Majority Banks shall, on or before the date of any
              requested A Borrowing to be made, notify the Agent that the
              Eurodollar Rate for Eurodollar Rate Advances comprising such A
              Borrowing will not adequately reflect the cost to such Banks of
              making their respective Eurodollar Rate Advances for such A
              Borrowing, the right of the Borrower to select Eurodollar Rate
              Advances for such A Borrowing or any subsequent A Borrowing shall
              be suspended until the Agent, at the request of the Majority
              Banks, shall notify the Borrower and the Banks that the
              circumstances causing such suspension no longer exist, and,
              except as provided in Section 2.02(b)(vi), each Advance
              comprising such A Borrowing shall be a Base Rate Advance;

       (v)    if less than two Reference Banks furnish timely information to
              the Agent for determining the Eurodollar Rate for Eurodollar Rate
              Advances, comprising any requested A Borrowing to be made, the
              right of the Borrower to select Eurodollar Rate Advances, as the
              case may be, for such A Borrowing or any subsequent A Borrowing
              shall be suspended until the Agent shall notify the Borrower and
              the Banks that the circumstances causing such suspension no
              longer exist, and, except as provided in Section 2.02(b)(vi),
              each Advance comprising such A Borrowing shall be a Base Rate
              Advance;





                                      -14-
<PAGE>   112
        (vi)  if the Borrower has requested a proposed A Borrowing
              consisting of Eurodollar Rate Advances and as a result of
              circumstances referred to in Section 2.02(b)(iii), (iv) or (v)
              such A Borrowing would not consist of Eurodollar Rate Advances,
              the Borrower may, by notice given not later than 2:00 P.M. (Dallas
              time) at least one Business Day prior to the date such proposed A
              Borrowing would otherwise be made, cancel such A Borrowing, in
              which case such A Borrowing shall be cancelled and no Advances
              shall be made as a result of such requested A Borrowing, but the
              Borrower shall indemnify the Banks in connection with such        
              cancellation as contemplated by Section 2.02(c); and
        
        (vii) if the Borrower shall fail to select the duration or continuation
              of any Interest Period for any Eurodollar Rate Advances in
              accordance with the provisions contained in the definition of
              "Interest Period" in Section 1.01 and this paragraph (b), the
              Agent will promptly so notify the Borrower and the Banks and such
              A Advances will be made available to the Borrower on the date of
              such A Borrowing as Base Rate Advances.

       (c)    Each Notice of A Borrowing shall be irrevocable and binding on
the Borrower, except as set forth in Section 2.02(b)(vi).  In the case of any A
Borrowing requested by the Borrower which the related Notice of A Borrowing
specifies is to be comprised of Eurodollar Rate Advances, the Borrower shall
indemnify each Bank against any loss, cost or expense incurred by such Bank as
a result of any failure to fulfill on or before the date specified in such
Notice of A Borrowing for such A Borrowing the applicable conditions set forth
in Article III, including, without limitation, any loss (including loss of
reasonably anticipated profits), cost or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by such Bank to
fund the A Advance to be made by such Bank as part of such A Borrowing when
such A Advance, as a result of such failure, is not made on such date.  A
certificate in reasonable detail as to the basis for and the amount of such
loss, cost or expense submitted to the Borrower and the Agent by such Bank
shall be prima facie evidence of the amount of such loss, cost or expense.  If
an A Borrowing requested by the Borrower which the related Notice of A
Borrowing specifies is to be comprised of Eurodollar Rate Advances is not made
as an A Borrowing comprised of Eurodollar Rate Advances as a result of Section
2.02(b), the Borrower shall indemnify each Bank against any loss (excluding
loss of profits), cost or expense incurred by such Bank by reason of the
liquidation or reemployment of deposits or other funds acquired by such Bank
(prior to the time such Bank is actually aware that such A Borrowing will not
be so made) to fund the A Advance to be made by such Bank as part of such A
Borrowing.  A certificate in reasonable detail as to the basis for and the
amount of such loss, cost or expense submitted to the Borrower and the Agent by
such Bank shall be prima facie evidence of the amount of such loss, cost or
expense.

       (d)    With respect to any new A Borrowing to be made on the last day of
an Interest Period, the Borrower and each Bank agree that any amounts payable
by the Borrower to such Bank in connection with maturing A Advances on the date
of such Borrowing shall be netted against the amount of the new Borrowing to be
funded by such Bank so as to eliminate where possible the need for actual
payment and readvancement of funds by the parties.  In the event of any A
Borrowing





                                      -15-
<PAGE>   113
subject to the conditions precedent in Section 3.03, unless the Agent shall
have received notice from a Bank prior to the date of any A Borrowing that such
Bank will not make available to the Agent such Bank's ratable portion of such A
Borrowing (to the extent in excess of any maturing A Advances payable to such
Bank), the Agent may assume that such Bank has made such portion available to
the Agent on the date of such A Borrowing in accordance with subsection (a) of
this Section 2.02 and the Agent may, in reliance upon such assumption, make
available to the Borrower requesting such A Borrowing on such date a
corresponding amount.  If and to the extent that such Bank shall not have so
made such ratable portion available to the Agent, such Bank and the Borrower
severally agree to repay to the Agent forthwith on demand such corresponding
amount together with interest thereon, for each day from the date such amount
is made available to the Borrower until the date such amount is repaid to the
Agent, at (i) in the case of the Borrower, the interest rate applicable at the
time to A Advances comprising such A Borrowing and (ii) in the case of such
Bank, the Federal Funds Rate.  If such Bank shall repay to the Agent such
corresponding amount, such amount so repaid shall constitute such Bank's A
Advance as part of such A Borrowing for purposes of this Agreement.

       (e)    The failure of any Bank to make the A Advance to be made by it as
part of any A Borrowing shall not relieve any other Bank of its obligation, if
any, hereunder to make its A Advance on the date of such A Borrowing, but no
Bank shall be responsible for the failure of any other Bank to make the A
Advance to be made by such other Bank on the date of any A Borrowing.

       Section 2.03.  Fees.
       
       (a)    Facility Fee.  The Borrower agrees to pay to each Bank a
facility fee calculated on the amount of such Bank's Commitment (regardless of
usage) from the date hereof until the Termination Date at the Applicable
Facility Fee per annum, payable in arrears on the last day of each calendar
quarter during the term of such Bank's Commitment, and on the Termination Date.

       (b)    Administrative Fee.  The Borrower agrees to pay to the Agent, for
its sole account, an administrative fee as set forth in the Agent's Fee Letter.

       (c)    Bid Request Fee.  The Borrower agrees to pay to the Agent on the
date of each request for B Advances pursuant to Section 2.08 a bid request fee
as set forth in the Agent's Fee Letter.

       (d)    Arrangement Fee.  The Borrower agrees to pay to the Agent on the
date of this Agreement an arrangement fee as set forth in the Agent's Fee
Letter.

       Section 2.04.  Optional Reduction of the Commitments.  The Borrower
shall have the right, upon at least five Business Days notice to the Agent, to
terminate in whole or reduce ratably in part the unused portions of the
respective Commitments of the Banks, provided that each partial reduction shall
be in the aggregate amount of at least $10,000,000, and provided further, that
the aggregate amount of the Commitments of the Banks shall not be reduced to an
amount which is less





                                      -16-
<PAGE>   114
than the aggregate principal amount of the Advances then outstanding.  Any such
reduction or termination of the Commitments shall be permanent.

       Section 2.05.  Repayment and Prepayment of A Advances.  (a) The unpaid
principal amount of each A Advance that is made by each Bank shall be repaid by
the Borrower in full on the last day of the Interest Period for such A Advance.


       (b)    The Borrower may, in respect of Base Rate Advances upon at least
one Business Days' notice, and, in respect of Eurodollar Rate Advances upon at
least three Business Days' notice, to the Agent stating the proposed date
(which shall be a Business Day) and aggregate principal amount of the
prepayment, and if such notice is given the Borrower shall, prepay the
outstanding principal amounts of the A Advances comprising part of the same A
Borrowing in whole or ratably in part, together with accrued interest to the
date of such prepayment on the principal amount prepaid and amounts, if any,
required to be paid pursuant to Section 2.10 as a result of such prepayment;
provided, however, that each partial prepayment pursuant to this Section
2.05(b) shall be in an aggregate principal amount not less than $5,000,000 and
in an aggregate principal amount such that after giving effect thereto no A
Borrowing comprised of Base Rate Advances shall have a principal amount
outstanding of less than $5,000,000 and no A Borrowing comprised of Eurodollar
Rate Advances shall have a principal amount outstanding of less than
$20,000,000.

       Section 2.06.  Interest on A Advances.  The Borrower shall pay interest
on the unpaid principal amount of each A Advance made by each Bank from the
date of such A Advance until such principal amount shall be paid in full, at
the following rates per annum:

       (a)    Base Rate Advances.  If such A Advance is a Base Rate Advance, a
rate per annum equal at all times during the Interest Period for such A Advance
to the Base Rate in effect from time to time during such Interest Period for
such A Advance, payable on the last day of such Interest Period.

       (b)    Eurodollar Rate Advances.  If such A Advance is a Eurodollar Rate
Advance, a rate per annum equal at all times during the Interest Period for
such A Advance to the sum of the Eurodollar Rate for such Interest Period plus
the Applicable Margin in effect from time to time for such A Advance, payable
on the last day of such Interest Period and, if such Interest Period has a
duration of more than three months, on each day which occurs during such
Interest Period every three months from the first day of such Interest Period.

       (c)    Additional Interest on Eurodollar Rate Advances.  The Borrower
shall pay to each Bank, so long as such Bank shall be required under
regulations of the Board of Governors of the Federal Reserve System to maintain
reserves with respect to liabilities or assets consisting of or including
Eurocurrency Liabilities, additional interest on the unpaid principal amount of
each Eurodollar Rate Advance of such Bank, from the date of such Advance until
such principal amount is paid in full, at an interest rate per annum equal at
all times to the remainder obtained by subtracting (i) the Eurodollar Rate for
the Interest Period for such Advance from (ii) the rate obtained





                                      -17-
<PAGE>   115
by dividing such Eurodollar Rate by a percentage equal to 100% minus the
Eurodollar Rate Reserve Percentage of such Bank for such Interest Period,
payable on each date on which interest is payable on such Advance.  Such
additional interest shall be determined by such Bank and notified to the
Borrower through the Agent.  A certificate as to the amount of such additional
interest submitted to the Borrower and the Agent by such Bank shall be
conclusive and binding for all purposes, absent manifest error.

       Section 2.07.  Interest Rate Determination.  (a) Each Reference Bank
agrees to furnish to the Agent timely information for the purpose of
determining each Eurodollar Rate.  If any of the Reference Banks shall not
furnish such timely information to the Agent for the purpose of determining any
such Eurodollar Rate, the Agent shall determine such Eurodollar Rate on the
basis of timely information furnished by the remaining Reference Banks, subject
to Section 2.02(b).

       (b)    The Agent shall give prompt notice to the Borrower and the Banks
of the applicable interest rate for such A Advance determined by the Agent for
purposes of Section 2.06(a) or (b), and the applicable rate, if any, furnished
by each Reference Bank for the purpose of determining the applicable interest
rate under Section 2.06(b).

       Section 2.08.  The B Advances.
       
       (a) Each Bank severally agrees that the Borrower may make B Borrowings
under this Section 2.08 from time to time on any Business Day during the period
from the date hereof until the date occurring 30 days prior to the Termination
Date in the manner set forth below; provided that, following the making of each
B Borrowing, the aggregate amount of the Advances then outstanding shall not
exceed the aggregate amount of the Commitments of the Banks (computed without
regard to any B Reduction).

       (i)    The Borrower may request a B Borrowing under this Section 2.08 by
              delivering to the Agent, not later than 9:00 A.M. (Dallas time)
              at least five Business Days prior to the date of the proposed B
              Borrowing, a notice of a B Borrowing (a "Notice of B Borrowing"),
              in substantially the form of Exhibit B-2 hereto, specifying the
              date and aggregate amount of the proposed B Borrowing, the
              maturity date for repayment of each B Advance to be made as part
              of such B Borrowing (which maturity date may not be earlier than
              the date occurring 14 days after the date of such B Borrowing or
              later than the earlier of 6 months after the date of such B
              Borrowing or the Termination Date), the interest payment date or
              dates relating thereto, and any other terms to be applicable to
              such B Borrowing (including, without limitation, the basis to be
              used by the Banks in determining the rate or rates of interest to
              be offered by them as provided in paragraph (ii) below and
              prepayment terms, if any, but excluding any waiver or other
              modification to any of the conditions set forth in Article III).
              The Borrower may not select a maturity date for any B Borrowing
              which ends after the Termination Date.  The Agent shall promptly
              notify each Bank of each request





                                      -18-
<PAGE>   116
              for a B Borrowing received by it from the Borrower by sending
              such Bank a copy of the related Notice of B Borrowing.

       (ii)   Each Bank may, if in its sole discretion it elects to do so,
              irrevocably offer to make one or more B Advances to the Borrower
              as part of such proposed B Borrowing at a rate or rates of
              interest specified by such Bank in its sole discretion, by
              notifying the Agent (which shall give prompt notice thereof to
              the Borrower), before 9:00 A.M. (Dallas time) three Business Days
              before the date of such proposed B Borrowing specified in the
              Notice of B Borrowing delivered with respect thereto pursuant to
              paragraph (i) above, of the minimum amount and maximum amount of
              each B Advance which such Bank would be willing to make as part
              of such proposed B Borrowing (which amounts may, subject to the
              proviso to the first sentence of this Section 2.08(a), exceed
              such Bank's Commitment), the rate or rates of interest therefor
              and such Bank's Applicable Lending Office with respect to such B
              Advance; provided that if the Agent in its capacity as a Bank
              shall, in its sole discretion, elect to make any such offer, it
              shall notify the Borrower of such offer before 8:45 A.M. (Dallas
              time) three Business Days before the date of the proposed B
              Borrowing specified in the Notice of B Borrowing delivered with
              respect thereto pursuant to paragraph (i) above.  Any Bank which
              has not notified the Agent of an offer prior to the time
              specified above shall be deemed to have elected not to make such
              an offer.

       (iii)  The Borrower shall, in turn, before 10:00 A.M. (Dallas time)
              three Business Days before the date of such proposed B Borrowing
              specified in the Notice of B Borrowing delivered with respect
              thereto pursuant to paragraph (i) above, either

                     (A)    cancel such B Borrowing by giving the Agent notice
                            to that effect, or

                     (B)    accept one or more of the offers made by any Bank
              or Banks pursuant to paragraph (ii) above, in its sole
              discretion, by giving notice to the Agent of the amount of each B
              Advance (which amount shall be equal to or greater than the
              minimum amount, and equal to or less than the maximum amount,
              notified to the Borrower by the Agent on behalf of such Bank for
              such B Advance pursuant to paragraph (ii) above) to be made by
              each Bank as part of such B Borrowing, and reject any remaining
              offers made by Banks pursuant to paragraph (ii) above by giving
              the Agent notice to that effect.

       (iv)   If the Borrower notifies the Agent that such B Borrowing is
              cancelled pursuant to paragraph (iii)(A) above, the Agent shall
              give prompt notice thereof to the Banks and such B Borrowing
              shall not be made.

       (v)    If the Borrower accepts one or more of the offers made by any
              Bank or Banks pursuant to paragraph (iii)(B) above, the Agent
              shall in turn promptly notify (A) each Bank that has made an
              offer as described in paragraph (ii) above, of the date and





                                      -19-
<PAGE>   117
       aggregate amount of such B Borrowing and whether or not any offer or
       offers made by such Bank pursuant to paragraph (ii) above have been
       accepted by the Borrower, (B) each Bank that is to make a B Advance as
       part of such B Borrowing, of the amount of each B Advance to be made by
       such Bank as part of such B Borrowing, and (C) each Bank that is to make
       a B Advance as part of such B Borrowing, upon receipt, that the Agent
       has received forms of documents appearing to fulfill the applicable
       conditions set forth in Article III.  Each Bank that is to make a B
       Advance as part of such B Borrowing shall, before 1:00 P.M. (Dallas
       time) on the date of such B Borrowing specified in the notice received
       from the Agent pursuant to clause (A) of the preceding sentence or any
       later time when such Bank shall have received notice from the Agent
       pursuant to clause (C) of the preceding sentence, make available for the
       account of its Applicable Lending Office to the Agent at its address
       referred to in Section 10.02 such Bank's portion of such B Borrowing, in
       same day funds.  Upon fulfillment of the applicable conditions set forth
       in Article III and after receipt by the Agent of such funds, the Agent
       will make such funds available to the Borrower at the Agent's aforesaid
       address.  Promptly after each B Borrowing the Agent will notify each
       Bank of the amount of the B Borrowing, the consequent B Reduction and
       the dates upon which such B Reduction commenced and will terminate.

       (b)    Each B Borrowing shall be in an aggregate amount of not less than
$5,000,000 or an integral multiple of $1,000,000 in excess thereof and,
following the making of each B Borrowing, the Borrower shall be in compliance
with the limitation set forth in the proviso to the first sentence of Section
2.08(a).

       (c)    Within the limits and on the conditions set forth in this Section
2.08, the Borrower may from time to time borrow under this Section 2.08, repay
pursuant to subsection (d) below, and reborrow under this Section 2.08,
provided that no B Borrowing shall be made within three Business Days of the
date of another B Borrowing.

       (d)    The Borrower shall repay to the Agent for the account of each
Bank which has made a B Advance to the Borrower on the maturity date of each B
Advance (such maturity date being that specified by the Borrower for repayment
of such B Advance in the related Notice of B Borrowing delivered pursuant to
subsection (a)(i) above) the then unpaid principal amount of such B Advance.
The Borrower shall not have any right to prepay any principal amount of any B
Advance unless, and then only on the terms, specified by the Borrower for such
B Advance in the related Notice of B Borrowing delivered pursuant to subsection
(a)(i) above and set forth in the B Note evidencing such B Advance.

       (e)    The Borrower shall pay interest on the unpaid principal amount of
each B Advance from the date of such B Advance to the date the principal amount
of such B Advance is repaid in full, at the rate of interest for such B Advance
specified by the Bank making such B Advance in its notice with respect thereto
delivered pursuant to subsection (a)(ii) above, payable on the interest





                                      -20-
<PAGE>   118
payment date or dates specified by the Borrower for such B Advance in the
related Notice of B Borrowing delivered pursuant to subsection (a)(i) above, as
provided in the B Note evidencing such B Advance.

       (f)    The indebtedness of the Borrower resulting from each B Advance
made to the Borrower as part of a B Borrowing shall be evidenced by a separate
B Note of the Borrower payable to the order of the Bank making such B Advance.

       Section 2.09.  Payments, Computations; Interest on Overdue Amounts.
       
       (a) The Borrower shall make each payment hereunder and under the Notes
to be made by it not later than 10:00 A.M. (Dallas time) on the day when due in
U.S. dollars to the Agent at its address referred to in Section 10.02 in same
day funds.  The Agent will promptly thereafter cause to be distributed like
funds relating to the payment of principal, interest or fees ratably (other
than amounts payable pursuant to Section 2.06(c), 2.08, 2.10, 2.11 or 2.13) to
the Banks for the account of their respective Applicable Lending Offices, and
like funds relating to the payment of any other amount payable to any Bank to
such Bank for the account of its Applicable Lending Office, in each case to be
applied in accordance with the terms of this Agreement.  In no event shall any
Bank be entitled to share any administrative fee paid to the Agent pursuant to
Section 2.03(b), any bid request fee paid to the Agent pursuant to Section
2.03(c) or any other fee paid to the Agent, as such.

       (b)    All computations of interest based on the Base Rate and of fees
shall be made by the Agent on the basis of a year of 365 or 366 days, as the
case may be, and all computations of interest based on the Eurodollar Rate or
the Federal Funds Rate shall be made by the Agent, and all computations of
interest pursuant to Section 2.06(c) shall be made by a Bank, on the basis of a
year of 360 days, in each case for the actual number of days (including the
first day but excluding the last day) occurring in the period for which such
interest or fees are payable.  Each determination by the Agent (or, in the case
of Section 2.06(c), by a Bank) of an interest rate hereunder shall be
conclusive and binding for all purposes, absent manifest error.

       (c)    Whenever any payment hereunder or under the Notes shall be stated
to be due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or fee, as the case may be;
provided, however, if such extension would cause payment of interest on or
principal of Eurodollar Rate Advances to be made in the next following calendar
month, such payment shall be made on the next preceding Business Day.

       (d)    Unless the Agent shall have received notice from the Borrower
prior to the date on which any payment is due by the Borrower to any Bank
hereunder that the Borrower will not make such payment in full, the Agent may
assume that the Borrower has made such payment in full to the Agent on such
date and the Agent may, in reliance upon such assumption, cause to be
distributed to each Bank on such due date an amount equal to the amount then
due such Bank.  If and to the extent the Borrower shall not have so made such
payment in full to the Agent, each Bank shall repay





                                      -21-
<PAGE>   119
to the Agent forthwith on demand such amount distributed to such Bank together
with interest thereon, for each day from the date such amount is distributed to
such Bank until the date such Bank repays such amount to the Agent, at the
Federal Funds Rate.

       (e)    Whenever any reference is made to any Bank's "ratable share" or
"ratable portion" (or any similar reference) of any amount hereunder, such
share or portion shall be calculated to not more than four decimal places,
rounding up or down, as appropriate.

       (f)    Any amount payable hereunder or under the Notes or under any
other Credit Document which is not paid when due (whether at stated maturity,
by acceleration or otherwise) shall bear interest, to the extent permitted by
law, from the date on which such amount became due until such amount is paid in
full, payable on demand, at a rate per annum equal at all times to:  (i) in the
case of any overdue principal of any Advance, the greater of (x) the sum of the
Base Rate in effect from time to time plus 2% per annum and (y) the sum of the
rate per annum required to be paid on such Advance immediately prior to the
date on which such amount became due plus 2% per annum, or (ii) in the case of
any interest, fee or other amount payable hereunder or under the Notes or under
any other Credit Document, the sum of the Base Rate in effect from time to time
plus 2% per annum.

       Section 2.10.  Consequential Losses.  If (a) any payment (or purchase
pursuant to Section 2.11(c)) of principal of any Eurodollar Rate Advance or B
Advance made to the Borrower is made other than on the last day of an Interest
Period relating to such Advance (or in the case of a B Advance, other than on
the original scheduled maturity date thereof), as a result of a prepayment
pursuant to Section 2.05(b) or 2.12 or acceleration of the maturity of the
Notes pursuant to Section 2.15 or Section 8.01 or for any other reason or as a
result of any such purchase; or (b) the Borrower fails to make a principal or
interest payment with respect to any Eurodollar Rate Advance or B Advance on
the date such payment is due and payable, the Borrower shall, upon demand by
any Bank (with a copy of such demand to the Agent), pay to the Agent for the
account of such Bank any amounts required to compensate such Bank for any
additional losses, costs or expenses which it may reasonably incur as a result
of any such payment or purchase, including, without limitation, any loss
(including loss of reasonably anticipated profits, except in the case of such a
purchase pursuant to Section 2.11(c)), cost or expense incurred by reason of
the liquidation or reemployment of deposits or other funds acquired by such
Bank to fund or maintain such Advance.

       Section 2.11.  Increased Costs.
       (a) If, due to either (i) the introduction of or any change (including
without limitation, but without duplication, any change by way of imposition or
increase of reserve requirements included, in the case of Eurodollar Rate
Advances, the Eurodollar Rate Reserve Percentage) in or in the interpretation,
application or applicability of any law or regulation or (ii) the compliance
with any guideline or request from any central bank or other governmental
authority (whether or not having the force of law), there shall be any increase
in the cost to any Bank of agreeing to make or making, funding or maintaining
any Fixed Rate Advance to the Borrower, then the Borrower shall from time





                                      -22-
<PAGE>   120
to time, upon demand by such Bank (with a copy of such demand to the Agent),
pay to the Agent for the account of such Bank additional amounts sufficient to
compensate such Bank for such increased cost.  A certificate as to the amount
of such increased cost, submitted to the Borrower and the Agent by such Bank,
shall be prima facie evidence of the amount of such increased cost.  Promptly
after any Bank becomes aware of any such introduction, change or proposed
compliance, such Bank shall notify the Borrower thereof, provided that the
failure to provide such notice shall not affect such Bank's rights hereunder,
except that such Bank's right to recover such increased costs from the Borrower
for any period prior to such notice shall be limited to the period of (i) 180
days, if such increased cost relates to any outstanding Advance, or (ii) 90
days, in each other event, immediately prior to the date such notice is given
to the Borrower.

       (b)    If any Bank determines that compliance with any law or regulation
or any guideline or request from any central bank or other governmental
authority (whether or not having the force of law) affects or would affect the
amount of capital required or expected to be maintained by such Bank or any
corporation controlling such Bank and that the amount of such capital is
increased by or based upon the existence of such Bank's commitment to lend to
the Borrower hereunder and other commitments of this type, then, upon demand by
such Bank (with a copy of such demand to the Agent), the Borrower shall
immediately pay to the Agent for the account of such Bank, from time to time as
specified by such Bank, additional amounts sufficient to compensate such Bank
or such corporation in the light of such circumstances, to the extent that such
Bank reasonably determines such increase in capital to be allocable to the
existence of such Bank's commitment to lend hereunder.  A certificate as to
such amounts submitted to the Borrower and the Agent by such Bank shall be
conclusive and binding for all purposes, absent manifest error.

       (c)    In the event that any Bank makes a demand for payment under
Section 2.06(c) or this Section 2.11, the Borrower may within ninety days of
such demand, if no Default then exists, replace such Bank with another
commercial bank in accordance with all of the provisions of the last sentence
of Section 10.06(a) (including execution of an appropriate Assignment) provided
that (i) all obligations of such Bank to lend hereunder shall be terminated and
the A Note and any B Note payable to such Bank and all other obligations owed
to such Bank hereunder shall be purchased in full without recourse at par plus
accrued interest at or prior to such replacement, (ii) such replacement bank
shall be reasonably satisfactory to the Agent, (iii) such replacement bank
shall, from and after such replacement, be deemed for all purposes to be a
"Bank" hereunder with a Commitment in the amount of the respective Commitment
of the assigning Bank immediately prior to such replacement (plus, if such
replacement bank is already a Bank prior to such replacement, the respective
Commitment of such Bank prior to such replacement), as such amount may be
changed from time to time pursuant hereto, and shall have all of the rights,
duties and obligations hereunder of the Bank being replaced, and (iv) such
other actions shall be taken by the Borrower, such Bank and such replacement
bank as may be appropriate to effect the replacement of such Bank with such
replacement bank on terms such that such replacement bank has all of the
rights, duties and obligations hereunder as such Bank (including, without
limitation, execution and delivery of new Notes to such replacement bank,
redelivery to the Borrower in due course of the Notes payable to





                                      -23-
<PAGE>   121
such Bank and specification of the information contemplated by Schedule I as to
such replacement bank).

       Section 2.12.  Illegality.  Notwithstanding any other provision of this
Agreement, if any Bank shall notify the Agent that the introduction of or any
change in or in the interpretation of any law or regulation shall make it
unlawful, or any central bank or other governmental authority shall assert that
it is unlawful, for any Bank or its Applicable Lending Office to make any Fixed
Rate Advance or to continue to fund or maintain any Fixed Rate Advance
hereunder, then, on notice thereof to the Borrower by the Agent, (i) the
obligation of each of the Banks to make any Fixed Rate Advance of the same Type
shall be suspended until the Agent shall notify the Borrower and the Banks that
the circumstances causing such suspension no longer exist, and (ii) the
Borrower shall forthwith prepay in full all Fixed Rate Advances then
outstanding of all Banks which are affected Fixed Rate Advances, together with
all accrued interest thereon and all amounts payable pursuant to Section 2.10,
unless each Bank shall determine in good faith in its sole opinion that it is
lawful to maintain the Fixed Rate Advances made by such Bank to the end of the
Interest Period then applicable thereto.

       Section 2.13.  Taxes.
       
       (a) Any and all payments by the Borrower or the Guarantor hereunder or
under the Notes or any other Credit Document shall be made, in accordance with
Section 2.09, free and clear of and without deduction for any and all present
or future taxes, levies, imposts, deductions, charges or withholdings with
respect thereto, and all liabilities with respect thereto, excluding in the
case of each Bank and the Agent, taxes imposed on its income, and franchise
taxes imposed on it, by the jurisdiction under the laws of which such Bank or
the Agent (as the case may be) is organized or any political subdivision
thereof and, in the case of each Bank, taxes imposed on its income, and
franchise taxes imposed on it, by the jurisdiction of such Bank's Applicable
Lending Office or any political subdivision thereof (all such non-excluded
taxes, levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes").  If the Borrower or the Guarantor shall be
required by law to deduct any Taxes from or in respect of any sum payable by it
hereunder or under any Note or other Credit Document to any Bank or the Agent,
(i) the sum payable shall be increased as may be necessary so that after making
all required deductions (including deductions applicable to additional sums
payable under this Section 2.13) such Bank or the Agent (as the case may be)
receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower or the Guarantor, as the case may be,
shall make such deductions and (iii) the Borrower or the Guarantor, as the case
may be, shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law.

       (b)    In addition, the Borrower or the Guarantor, as the case may be,
agrees to pay any present or future stamp or documentary taxes or any other
excise or property taxes, charges or similar levies which arise from any
payment made by the Borrower or the Guarantor hereunder or under any Note or
other Credit Document executed by it or from the execution, delivery or





                                      -24-
<PAGE>   122
registration of, or otherwise with respect to, this Agreement or any Note or
other Credit Document (hereinafter referred to as "Other Taxes").

       (c)    THE BORROWER AND THE GUARANTOR WILL INDEMNIFY EACH BANK, EACH CO-
AGENT, THE ARRANGER & SYNDICATION AGENT AND THE AGENT FOR THE FULL AMOUNT OF
TAXES OR OTHER TAXES (INCLUDING, WITHOUT LIMITATION, ANY TAXES OR OTHER TAXES
IMPOSED BY ANY JURISDICTION ON AMOUNTS PAYABLE UNDER THIS SECTION 2.13) OWED
AND PAID BY SUCH BANK, SUCH CO-AGENT, THE ARRANGER & SYNDICATION AGENT OR THE
AGENT (AS THE CASE MAY BE) AND ANY LIABILITY (INCLUDING PENALTIES, INTEREST AND
EXPENSES) ARISING THEREFROM OR WITH RESPECT THERETO.  THIS INDEMNIFICATION
SHALL BE MADE WITHIN 30 DAYS FROM THE DATE SUCH BANK, SUCH CO-AGENT, THE
ARRANGER & SYNDICATION AGENT OR THE AGENT (AS THE CASE MAY BE) MAKES WRITTEN
DEMAND THEREFOR.

       (d)    Within 30 days after the date of the payment of Taxes by or at
the direction of the Borrower or the Guarantor, the Borrower will furnish to
the Agent, at its address referred to in Section 10.02, the original or a
certified copy of a receipt evidencing payment thereof.

       (e)    Without prejudice to the survival of any other agreement of the
Borrower or the Guarantor hereunder, the agreements and obligations of the
Borrower and the Guarantor contained in this Section 2.13 shall survive the
payment in full of principal and interest hereunder and under the Notes and
other Credit Documents.

       (f)    Each Bank that is not incorporated under the laws of the United
States of America or a state thereof agrees that it will deliver to the
Borrower and the Agent on the date of this Agreement or upon the effectiveness
of any Assignment and Acceptance (i) two duly completed copies of United States
Internal Revenue Service Form 1001 or 4224 or successor applicable form, as the
case may be, certifying in each case that such Bank is entitled to receive
payments under this Agreement and the Notes payable to it, without deduction or
withholding of any United States federal income taxes, (ii) if applicable, an
Internal Revenue Service Form W-8 or W-9 or successor applicable form, as the
case may be, to establish an exemption from United States backup withholding
tax, and (iii) any other governmental forms which are necessary or required
under an applicable tax treaty or otherwise by law to reduce or eliminate any
withholding tax, which have been reasonably requested by the Borrower.  Each
Bank which delivers to the Borrower and the Agent a Form 1001 or 4224 and Form
W-8 or W-9 pursuant to the next preceding sentence further undertakes to
deliver to the Borrower and the Agent two further copies of the said Form 1001
or 4224 and Form W-8 or W-9, or successor applicable forms, or other manner of
certification, as the case may be, on or before the date that any such form
expires or becomes obsolete or after the occurrence of any event requiring a
change in the most recent form previously delivered by it to the Borrower and
the Agent, and such extensions or renewals thereof as may reasonably be
requested by the Borrower and the Agent certifying in the case of a Form 1001
or 4224 that such Bank is





                                      -25-
<PAGE>   123
entitled to receive payments under this Agreement without deduction or
withholding of any United States federal income taxes.  The Borrower shall
withhold tax at the rate and in the manner required by the laws of the United
States with respect to payments made to a Bank failing to timely provide the
requisite Internal Revenue Service forms.

       Section 2.14.  Payments Pro Rata.  Except as provided in Sections
2.03(b), 2.03(c), 2.03(d), 2.06(c), 2.10, 2.11, or 2.13, each of the Banks
agrees that if it should receive any payment (whether by voluntary payment, by
realization upon security, by the exercise of the right of setoff or banker's
lien, by counterclaim or cross action, by the enforcement of any right under
this Agreement or the Notes or other Credit Documents, or otherwise) in respect
of any obligation of the Borrower or Guarantor hereunder or under the Notes or
other Credit Documents of a sum which with respect to the related sum or sums
received by other Banks is in a greater proportion than the total amount of
principal, interest, fees or any other obligation incurred hereunder, as the
case may be, then owed and due to such Bank bears to the total amount of
principal, interest, fees or any such other obligation then owed and due to all
of the Banks immediately prior to such receipt, then such Bank receiving such
excess payment shall purchase for cash without recourse from the other Banks an
interest in the obligations of the Borrower to such Banks in such amount as
shall result in a proportional participation by all of the Banks in the
aggregate unpaid amount of principal, interest, fees or any such other
obligation, as the case may be, owed to all of the Banks, provided that if all
or any portion of such excess payment is thereafter recovered from such
purchasing Bank, such purchase from each other Bank shall be rescinded and each
such other Bank shall repay to the purchasing Bank the purchase price to the
extent of such other Bank's ratable share (according to the proportion of (i)
the amount of the participation purchased from such other Bank as a result of
such excess payment to (ii) the total amount of such excess payment) of such
recovery together with an amount equal to such other Bank's ratable share
(according to the proportion of (i) the amount of such other Bank's required
repayment to (ii) the total amount so recovered from the purchasing Bank) of
any interest or other amount paid or payable by the purchasing Bank in respect
of the total amount so recovered.  The Borrower agrees that any Bank so
purchasing a participation from another Bank pursuant to this Section 2.14 may,
to the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off) with respect to such participation as fully as
if such Bank were the direct creditor of the Borrower in the amount of such
participation.

       Section 2.15. Increase of Aggregate Commitments.  Provided no Default
has occurred and is continuing, the Borrower may by written notice to the Agent
and the Banks request that the aggregate amount of the Commitments hereunder be
increased up to the Aggregate Commitment Limit; provided, however that in the
event the Parallel Agreement is still in effect, (a) the Borrower shall
simultaneously request a pro rata increase in the aggregate amount of the
Parallel Agreement Commitments pursuant to Section 2.15 of the Parallel
Agreement, and (b) after giving effect to such increase of the aggregate
Commitments and such pro rata increase of the aggregate Parallel Agreement
Commitments, the total amount of all Commitments and all Parallel Agreement
Commitments shall not exceed the Aggregate Commitment Limit.  Upon the
Borrower's receipt of (a) incremental commitments from such Banks that may
agree to provide an increased Commitment hereunder, and if the Parallel
Agreement is still in effect, an increased Parallel Agreement





                                      -26-
<PAGE>   124
Commitment under the Parallel Agreement (there being no obligation on the part
of any Bank at any time hereunder to increase such Bank's Commitment or such
Bank's Parallel Agreement Commitment but any such increase agreed upon by any
Bank to be pro rata between this Agreement and the Parallel Agreement so that
its ratable percentage of each is the same) and/or (b) commitments from new
lenders willing to become a Bank with a Commitment hereunder, and if the
Parallel Agreement is still in effect, a "Bank" under the Parallel Agreement
with a pro rata Parallel Agreement Commitment, then such increase of the
aggregate Commitments shall become effective simultaneously with any such
increase of the aggregate Parallel Agreement Commitments when the following
conditions precedent and, if applicable, the conditions precedent set forth in
Section 2.15 of the Parallel Agreement have been satisfied and the Agent shall
have notified the parties hereto to such effect:

       (i)    The Borrower shall have delivered to the Agent, with sufficient
copies for each Bank (A) a certificate of the Chief Financial Officer of the
Borrower addressed to the Banks to the effect that, to the best of such
officer's knowledge, (x) no Default or Event of Default has occurred and is
continuing (or would result from the incurrence of the additional Debt
contemplated by this Section 2.15), and (y) all representations and warranties
herein or in any other Credit Document are true and correct in all material
respects with the same effect as if these representations and warranties had
been made on the date of such certificate (it being understood and agreed that
any representation which by its terms is made as of a specified date shall be
required to be true and correct in all material respects only as of such
specified date), and (B) unless the documentation delivered in connection with
the effectiveness of this Agreement otherwise authorizes Debt hereunder and
under the Parallel Agreement in an aggregate amount up to the Aggregate
Commitment Limit, a certificate of the Borrower's Secretary certifying that the
Borrower has been duly authorized by resolution of the Borrower's Board of
Directors to incur Debt hereunder and, if the Parallel Agreement is still in
effect, under the Parallel Agreement in an amount equal to or exceeding the
increased aggregate amount of the Commitments and, if the Parallel Agreement is
still in effect, the Parallel Agreement Commitments.

       (ii)   An Accession Agreement for each New Bank shall have been duly
executed by each party thereto.

       (iii)  The Agent has received the written consent of each Bank which has
agreed to increase  its Commitment hereunder (but no other Bank's consent shall
be required), such consent to be substantially in the form of the Consent to
Increase of Commitment attached as Exhibit G.

       (iv)    New Notes (including without limitation substitute Notes for
those Banks which have agreed to increase their respective Commitments) shall
have been executed and delivered by the Borrower in substantially the form of
Exhibits A-1 and A-2, as appropriate.

       (v)     No A Advances are outstanding hereunder as of the date such
increase is to become effective, or any such Advances are contemporaneously
repaid on such date.

       (f)    Termination of Existing Credit Agreement.  The Agent, the Co-

1995 among the Borrower, the Guarantor, the banks and co-agents parties

as a whole, or (ii) the Guarantor and its Subsidiaries taken as a whole.

       Section 3.02.  Conditions Precedent to Each A Borrowing.  The obligation
of each Bank to make an A Advance on the occasion of any A Borrowing (including
the initial Borrowing) shall be subject to the further conditions precedent
that on the date of such A Borrowing the following statements shall be true
(and each of the giving of the applicable Notice of A Borrowing and the
acceptance by the Borrower of the proceeds of such A Borrowing shall constitute
a representation and warranty by the Borrower that on the date of such A
Borrowing such statements are true):

       (i)    the representations and warranties contained in Article V (other
              than in Section 5.05 and Section 5.06) are correct on and as of
              the date of such A Borrowing, before and after giving effect to
              such A Borrowing and to the application of the proceeds
              therefrom, as though made on and as of such date,

       (ii)   no event has occurred and is continuing, or would result from
              such A Borrowing or from the application of the proceeds
              therefrom, which constitutes an Event of Default, and

       (iii)  after giving effect to such A Borrowing and all other Borrowings
              which have been requested on or prior to such date but which have
              not been made prior to such date,





                                      -29-
<PAGE>   127
       the aggregate principal amount of all Borrowings will not exceed the
       aggregate of the Commitments;

and the Agent shall have received such other approvals, opinions or documents
as any Bank through the Agent may reasonably request.

       Section 3.03.  Conditions Precedent to Certain Borrowings.  The
obligation of each Bank to make that portion of an A Advance on the occasion of
any A Borrowing which would increase the aggregate outstanding amount of A
Advances owing to such Bank over the aggregate amount of A Advances owing to
such Bank outstanding immediately prior to the making of such Advance shall in
each case be subject to the further condition precedent that on the date of
such Borrowing, no Default occurred and is continuing, or would result from
such Borrowing or from the application of the proceeds therefrom (and each of
the giving of the applicable Notice of Borrowing and the acceptance by the

                                   ARTICLE IV

                                    GUARANTY

       Section 4.01.  Guaranty.  The Guarantor hereby unconditionally
guarantees the punctual payment of the Guaranteed Obligations when due, whether
at stated maturity, by acceleration or otherwise, and agrees to pay any and all
expenses (including counsel fees and expenses) incurred by the Agent or any
Bank in enforcing any rights hereunder.  Without limiting the generality of the
foregoing, the Guarantor's liability shall extend to all amounts which
constitute part of the Guaranteed Obligations and would be owed by the Borrower
under this Agreement or any of the Notes but for the fact that the claims to
such amounts are, or are deemed to be, stayed, unenforceable, not allowable,
discharged, or otherwise reduced, restricted or limited in any manner due to
the existence of a bankruptcy, reorganization or similar proceeding involving
the Borrower.

       Section 4.02.  Guaranty Absolute.  The Guarantor guarantees that the
Guaranteed Obligations will be paid strictly in accordance with the terms of
the Credit Documents executed from time to time by the Borrower, regardless of
any law, regulation or order now or hereafter in effect in any jurisdiction
affecting any of such terms or the rights of the Agent or any Bank with respect
thereto.  The obligations of the Guarantor hereunder are independent of the
Guaranteed Obligations, and provided an Event of Default exists as to the
Borrower and is continuing at the time an action is brought, a separate action
or actions may be brought and prosecuted against the Guarantor to enforce this
Agreement, irrespective of whether any action is brought against the Borrower
or whether the Borrower is joined in any such action or actions.  The liability
of the Guarantor hereunder shall be absolute and unconditional irrespective of:

              (i)    any lack of validity or enforceability of any of the
       Credit Documents against the Borrower;

              (ii)   any change in the time, manner or place of payment of, or
       in any other term of, all or any of the Guaranteed Obligations or any
       other liabilities, or any other amendment or waiver of or any consent to
       departure from any of the Credit Documents, including, without
       limitation, any increase in the Guaranteed Obligations or any other
       liabilities resulting from the making of additional Advances guaranteed
       by the Guarantor to the Borrower or otherwise;

              (iii)  any taking, exchange, release or non-perfection of any
       collateral, or any taking, release or amendment or waiver of or consent
       to departure from any other guaranty, for all or any of the Guaranteed
       Obligations or any other liabilities;





                                      -31-
<PAGE>   129
              (iv)   any manner of application of collateral, or proceeds
       thereof, to all or any of the Guaranteed   Obligations or any other
       liabilities, or any manner of sale or other disposition of any collateral
       for all or any of the Guaranteed Obligations or any other liabilities or
       any other assets of the Borrower or any of its Subsidiaries;
        
              (v)    any change, restructuring or termination of the corporate
       structure or existence of the Borrower or any of its Subsidiaries; or

              (vi)   any other circumstances which might otherwise constitute a
       defense available to, or a discharge of, the Borrower or a guarantor.

       This guaranty shall continue to be effective or be reinstated, as the
case may be, if at any time any payment of any of the Guaranteed Obligations is
rescinded or must otherwise be returned by the Agent or any Bank upon the
insolvency, bankruptcy or reorganization of the Borrower or otherwise, all as
though such payment had not been made.

       Section 4.03.  Waiver.  The Guarantor hereby waives promptness,
diligence, notice of acceptance and any other notice with respect to any of the
Guaranteed Obligations and this Guaranty and any requirement that the Agent or
any Bank protect, secure, perfect or insure any security interest or lien or
any property subject thereto or exhaust any right to take any action against
the Borrower or any other Person or any collateral.

       Section 4.04.  Subrogation.  The Guarantor irrevocably waives any and
all rights to which it may be entitled, by operation of law or otherwise, upon
making any payment hereunder (i) to be subrogated to the rights of the Agent
and the Banks against the Borrower or any other Person with respect to such
payment or otherwise to be reimbursed, indemnified or exonerated by the
Borrower or any other Person in respect thereof or (ii) to receive any payment,
in the nature of contribution or for any other reason, from any Person who has
provided security for the Guaranteed Obligations or who has also guaranteed or
is otherwise liable for the Guaranteed Obligations with respect to which such
payment was made.  If any amount shall be paid to the Guarantor on account of
such subrogation or contribution rights at any time, such amount shall be held
in trust for the benefit of the Banks and shall forthwith be paid to the Agent
to be credited and applied upon the Guaranteed Obligations, whether matured or
unmatured, in such order as may be determined by the Agent.

       Section 4.05.  No Waiver; Remedies.  No failure on the part of the Agent
or any Bank to exercise, and no delay in exercising, any right hereunder shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right hereunder preclude any other or further exercise thereof or the exercise
of any other right.  The remedies herein provided are cumulative and not
exclusive of any remedies provided by law.

       Section 4.06.  Continuing Guaranty.  This guaranty is a continuing
guaranty and shall (i) remain in full force and effect until the later of (A)
the payment in full of the Guaranteed Obligations and all other amounts payable
under this guaranty and (B) the expiration or termination





                                      -32-
<PAGE>   130
of each Commitment of each Bank to the Borrower, (ii) be binding upon the
Guarantor, its successors and assigns, (iii) inure to the benefit of, and be
enforceable by, the Agent, the Co-Agents, the Arranger & Syndication Agent, and
each of the Banks and their respective successors, transferees and assigns, and
(iv) not be terminated by the Guarantor or the Borrower.

qualified, as a foreign corporation in each jurisdiction in which qualification
is necessary or desirable in view of its business and operations or the
ownership of its properties, except in the case of any Subsidiary where the
failure of such Subsidiary to so preserve, maintain, qualify and remain
qualified could not reasonably be expected to have a material adverse effect on

imposed upon it or upon its income or profits of property that are material in
amount, prior to the date on which penalties attach thereto and (b) all lawful
claims that are material in amount which, if unpaid, might by law become a Lien
upon its property; provided, however, that neither the Borrower, the Guarantor,
nor any such Subsidiary shall be required to pay or discharge any such tax,
assessment, charge, levy, or claim which is being contested in good faith and
by appropriate proceedings, and with respect to which reserves in conformity
with generally accepted accounting principles have been provided.

unsatisfied and either (i) enforcement proceedings shall have been commenced by
any creditor upon such judgments or orders or (ii) there shall be any period of
30 consecutive days during which a stay of enforcement of such judgments or
orders, by reason of a pending appeal or otherwise, shall not be in effect; or

       (g)    any Termination Event with respect to a Plan shall have occurred
and, 30 days after notice thereof shall have been given to the Borrower and the
Guarantor by the Agent, (i) such Termination Event shall still exist and (ii)

         THE AGENT, THE CO-AGENTS, AND THE ARRANGER & SYNDICATION AGENT

       Section 9.01.  Authorization and Action.  Each Bank hereby appoints and
authorizes the Agent to take such action as agent on its behalf and to exercise
such powers under the Credit Documents as are delegated to the Agent by the
terms hereof and thereof, together with such powers as are reasonably
incidental thereto.  As to any matters not expressly provided for by the Credit
Documents (including, without limitation, enforcement or collection of the
Notes), the Agent shall not be required to exercise any discretion or take any
action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions
of the Majority Banks, and such instructions shall be binding upon all Banks
and all holders of Notes; provided, however, that the Agent shall not be
required to take any action which exposes the Agent to personal liability or
which is contrary to any Credit Document or applicable law.  The Agent agrees
to give to each Bank prompt notice of each notice given to it by the Borrower
pursuant to the terms of this Agreement.

       Section 9.02.  Agent's Reliance, Etc.  Neither the Agent nor any of its
directors, officers, agents or employees shall be liable for any action taken
or omitted to be taken by it or them under or in connection with the Credit
Documents, except for its or their own gross negligence or willful misconduct.
Without limitation of the generality of the foregoing, the Agent:  (i) may
treat the payee of any Note as the holder thereof until the Agent receives and
accepts an Assignment executed by the Borrower, the Bank which is the payee of
such Note, as assignor, and the assignee in accordance with Section 10.06; (ii)
may consult with legal counsel (including counsel for the Borrower),
independent public accountants and other experts selected by it and shall not
be liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants or experts; (iii) makes
no warranty or representation to any Bank and shall not be responsible to any
Bank for any statements, warranties or representations made in or in connection
with the Credit Documents; (iv) shall not have any duty to ascertain or to
inquire as to the performance or observance of any of the terms, covenants or
conditions of the Credit Documents on the part of the Borrower or the Guarantor
or to inspect the property (including the books and records) of the Borrower or
the Guarantor; (v) shall not be responsible to any Bank for the due execution,
legality, validity, enforceability, genuineness, sufficiency or value of the
Credit Documents; and (vi) shall incur no liability under or in respect of the
Credit Documents by acting upon any notice, consent, certificate or other
instrument or writing (which may be by telecopier, telegram, cable or telex)
believed by it to be genuine and signed or sent by the proper party or parties.

       Section 9.03.  NationsBank and Affiliates.  With respect to its
Commitment, the Advances made by it and the Notes issued to it, NationsBank
shall have the same rights and powers under the Credit Documents and any Note
payable to NationsBank as any other Bank and may exercise the same as though it
was not the Agent; and the term "Bank" or "Banks" shall, unless otherwise





                                      -46-
<PAGE>   144
expressly indicated, include NationsBank in its individual capacity.
NationsBank and its affiliates may accept deposits from, lend money to, act as
trustee under indentures of, and generally engage in any kind of business with,
the Borrower, the Guarantor, any Subsidiary of the Borrower or the Guarantor
and any Person who may do business with or own securities of the Borrower, the
Guarantor, or any such Subsidiary, all as if NationsBank were not the Agent and
without any duty to account therefor to the Banks.

       Section 9.04.  Bank Credit Decision.  Each Bank acknowledges that it
has, independently and without reliance upon the Agent, the Arranger &
Syndication Agent or any other Bank and based on the financial statements
referred to in Section 5.05 and such other documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into
this Agreement.  Each Bank also acknowledges that it will, independently and
without reliance upon the Agent, the Arranger & Syndication Agent or any other
Bank and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under the Credit Documents.

       SECTION 9.05.  INDEMNIFICATION.  THE BANKS AGREE TO INDEMNIFY THE AGENT,
EACH CO-AGENT, AND THE ARRANGER & SYNDICATION AGENT (TO THE EXTENT NOT
REIMBURSED BY THE BORROWER OR THE GUARANTOR), RATABLY ACCORDING TO THE
RESPECTIVE PRINCIPAL AMOUNTS OF THE A NOTES THEN HELD BY EACH OF THEM (OR IF NO
A NOTES ARE AT THE TIME OUTSTANDING OR IF ANY A NOTES ARE HELD BY PERSONS WHICH
ARE NOT BANKS, RATABLY ACCORDING TO EITHER (I) THE RESPECTIVE AMOUNTS OF THEIR
COMMITMENTS, OR (II) IF ALL COMMITMENTS HAVE TERMINATED, THE RESPECTIVE AMOUNTS
OF THE COMMITMENTS IMMEDIATELY PRIOR TO THE TIME THE COMMITMENTS TERMINATED),
FROM AND AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES,
PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS OF ANY
KIND OR NATURE WHATSOEVER WHICH MAY BE IMPOSED ON, INCURRED BY, OR ASSERTED
AGAINST THE AGENT, SUCH CO-AGENT OR THE ARRANGER & SYNDICATION AGENT IN ANY WAY
RELATING TO OR ARISING OUT OF THE CREDIT DOCUMENTS OR ANY ACTION TAKEN OR
OMITTED BY THE AGENT UNDER THE CREDIT DOCUMENTS, PROVIDED THAT NO BANK SHALL BE
LIABLE TO THE AGENT, ANY CO-AGENT OR THE ARRANGER & SYNDICATION AGENT FOR ANY
PORTION OF SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS,
JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING FROM THE AGENT'S,
SUCH CO-AGENT'S OR THE ARRANGER & SYNDICATION AGENT'S GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT.  WITHOUT LIMITATION OF THE FOREGOING, EACH BANK AGREES TO
REIMBURSE THE AGENT PROMPTLY UPON DEMAND FOR ITS RATABLE SHARE OF ANY
OUT-OF-POCKET EXPENSES (INCLUDING COUNSEL





                                      -47-
<PAGE>   145
FEES) INCURRED BY THE AGENT IN CONNECTION WITH THE PREPARATION, EXECUTION,
DELIVERY, ADMINISTRATION, MODIFICATION, AMENDMENT OR ENFORCEMENT (WHETHER
THROUGH NEGOTIATIONS, LEGAL PROCEEDINGS OR OTHERWISE) OF, OR LEGAL ADVICE IN
RESPECT OF RIGHTS OR RESPONSIBILITIES UNDER, THE CREDIT DOCUMENTS TO THE EXTENT
THAT THE AGENT IS NOT REIMBURSED FOR SUCH EXPENSES BY THE BORROWER OR THE
GUARANTOR.

       Section 9.06.  Successor Agent.  The Agent may resign at any time as
Agent under this Agreement by giving written notice thereof to the Banks and
the Borrower and may be removed at any time by the Borrower if at any time the
Agent, in its individual capacity as a Bank hereunder, shall hold less than
$30,000,000 of the aggregate Commitments.  Upon any such resignation or
removal, the Borrower shall have the right to appoint, with the consent of the
Majority Banks (which consent shall not be unreasonably withheld), a successor
Agent.  If no successor Agent shall have been so appointed by the Borrower with
such consent of the Majority Banks, and shall have accepted such appointment,
within 30 days after the retiring Agent's giving of notice of resignation or
the Borrower's removal of the retiring Agent, then the retiring Agent may, on
behalf of the Banks, appoint a successor Agent, which shall be a Bank which is
a commercial bank organized under the laws of the United States of America or
of any State thereof and having a combined capital and surplus of at least
$500,000,000.  Upon the acceptance of any appointment as Agent under this
Agreement by a successor Agent, such successor Agent shall thereupon succeed to
and become vested with all the rights, powers, privileges and duties of the
retiring Agent and shall function as the Agent under this Agreement, and the
retiring Agent shall be discharged from its duties and obligations as Agent
under this Agreement.  After any retiring Agent's resignation or removal
hereunder as Agent, the provisions of this Article IX shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent
under this Agreement.

       Section 9.07.  Co-Agents; Arranger & Syndication Agent.  The Co-Agents
and the Arranger & Syndication Agent shall have no duties, obligations, or
liabilities in their capacities as such.

                                 MISCELLANEOUS

       Section 10.01.  Amendments, Etc.  No amendment or waiver of any
provision of any Credit Document, nor consent to any departure by the Borrower
or the Guarantor therefrom, shall in any event be effective unless the same
shall be in writing and signed by the Borrower and the Majority Banks, and then
such waiver or consent shall be effective only in the specific instance and for
the specific purpose for which given; provided, however, that no amendment,

Guarantor under any Credit Document; and provided, further, that no increase
may be made with respect to any Bank's Commitment without the consent of such
Bank.

provided for hereunder shall be in writing (including telecopy, telegraphic,

       Section 10.04.  Costs, Expenses and Taxes.

       (a) The Borrower agrees to pay on demand (i) all reasonable costs
and expenses of the Agent in connection with the preparation, execution,

including, without limitation, the reasonable fees and out-of-pocket expenses
of counsel for the Agent with respect thereto and with respect to advising the

fees and expenses, which may include inside counsel), of the Agent and each
Bank in connection with the enforcement (whether through negotiations, legal
proceedings or otherwise) against the Borrower or the Guarantor of any Credit
Document.

       (b)    THE BORROWER AGREES, TO THE FULLEST EXTENT PERMITTED BY LAW, TO
INDEMNIFY AND HOLD HARMLESS THE AGENT, EACH CO-AGENT, THE ARRANGER &
SYNDICATION AGENT AND EACH BANK AND EACH OF THEIR RESPECTIVE DIRECTORS,
OFFICERS, EMPLOYEES AND AGENTS FROM AND AGAINST ANY AND ALL CLAIMS, DAMAGES,
LIABILITIES AND EXPENSES (INCLUDING, WITHOUT LIMITATION, REASONABLE FEES AND
DISBURSEMENTS OF COUNSEL) FOR WHICH ANY OF THEM MAY BECOME LIABLE OR WHICH MAY
BE INCURRED BY OR ASSERTED AGAINST THE AGENT, SUCH CO-AGENT, THE ARRANGER &
SYNDICATION AGENT OR SUCH BANK OR ANY SUCH DIRECTOR, OFFICER, EMPLOYEE OR AGENT
(OTHER THAN BY ANOTHER BANK OR ANY SUCCESSOR OR ASSIGN OF ANOTHER BANK), IN
EACH CASE IN CONNECTION WITH OR ARISING OUT OF OR BY REASON OF ANY
INVESTIGATION, LITIGATION, OR PROCEEDING, WHETHER OR NOT THE AGENT, SUCH CO-
AGENT, THE ARRANGER & SYNDICATION AGENT OR SUCH BANK OR ANY SUCH DIRECTOR,
OFFICER, EMPLOYEE OR AGENT IS A PARTY THERETO, ARISING OUT OF, RELATED TO OR IN
CONNECTION WITH ANY CREDIT DOCUMENT OR ANY TRANSACTION IN WHICH ANY PROCEEDS OF
ALL OR ANY PART OF THE ADVANCES ARE APPLIED (OTHER THAN ANY SUCH CLAIM, DAMAGE,
LIABILITY OR EXPENSE TO THE EXTENT ATTRIBUTABLE TO THE GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT OF, OR VIOLATION OF ANY LAW OR REGULATION BY, ANY SUCH
INDEMNIFIED PARTY).

       Section 10.05.  Right of Set-off.  Upon (i) the occurrence and during
the continuance of any Event of Default and (ii) the making of the request or
the granting of the consent specified by Section 8.01 to authorize the Agent to
declare the Notes due and payable pursuant to the provisions of Section 8.01,
each Bank is hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by such Bank to or for the credit or the
account of the Borrower or the Guarantor against any and all of the obligations





                                      -50-
<PAGE>   148
of the Borrower or the Guarantor now or hereafter existing under the Credit
Documents, irrespective of whether or not such Bank shall have made any demand
under this Agreement or such Notes and although such obligations may be
unmatured.  Each Bank agrees promptly to notify the Borrower and the Guarantor
after such set-off and application made by such Bank, provided that the failure
to give such notice shall not affect the validity of such set-off and
application.  The rights of each Bank under this Section are in addition to
other rights and remedies (including, without limitation, other rights of
set-off) which such Bank may have.

       Section 10.06.  Bank Assignments and Participations.
       
       (a)    Assignments.  Any Bank may assign to one or more banks or
other entities all or any portion of its rights and obligations under this
Agreement (including, without limitation, all or a portion of its Commitment,
the Advances owing to it, and the Notes held by it); provided, however, that
(i) each such assignment of an Assigning Bank's Commitment shall be of a
constant, and not a varying, percentage of all of such Bank's rights and
obligations under this Agreement in respect of such Commitment and such Bank
shall simultaneously assign a pro rata portion of  such Bank's rights and
obligations in respect of its Parallel Agreement Commitment so that its pro
rata percentage of each of the Commitments and the Parallel Agreement
Commitments is the same, (ii) the amount of the resulting Commitment and
Advances of the assigning Bank (unless it is assigning all its Commitment and
all of its Parallel Agreement Commitment) and the assignee Bank pursuant to
each such assignment (determined as of the date of the Assignment with respect
to such assignment) shall in no event be less than $10,000,000 and shall be an
integral multiple of $1,000,000, (iii) each such assignment shall be to an
Eligible Assignee, (iv) the parties to each such assignment shall execute and
deliver to the Agent, for its acceptance and recording in the Register, an
Assignment, together with the Note or Notes subject to such assignment, and (v)
each Eligible Assignee not already a Bank hereunder shall pay to the Agent an
assignment fee of $3000 in connection with such assignment.  Upon such
execution, delivery, acceptance and recording, from and after the effective
date specified in each Assignment, which effective date shall be at least three
Business Days after the execution thereof, (A) the assignee thereunder shall be
a party hereto for all purposes and, to the extent that rights and obligations
hereunder have been assigned to it pursuant to such Assignment, have the rights
and obligations of a Bank hereunder and (B) such Bank thereunder shall, to the
extent that rights and obligations hereunder have been assigned by it pursuant
to such Assignment, relinquish its rights and be released from its obligations
under this Agreement (and, in the case of an Assignment covering all or the
remaining portion of such Bank's rights and obligations under this Agreement,
such Bank shall cease to be a party hereto).

       (b)    Terms of Assignments.  By executing and delivering an Assignment,
the Bank thereunder and the assignee thereunder confirm to and agree with each
other and the other parties hereto the matters set forth in paragraphs 2 and 3
of such Assignment.





                                      -51-
<PAGE>   149
       (c)    The Register.  The Agent shall maintain at its address referred
to on Schedule I a copy of each Assignment delivered to and accepted by it and
a register for the recordation of the names and addresses of the Banks and the
Commitments of, and principal amount of the Advances owing to, each Bank from
time to time (the "Register").  The entries in the Register shall be conclusive
and binding for all purposes, absent manifest error, and the Borrower, the
Guarantor, the Agent, and the Banks may treat each Person whose name is
recorded in the Register as a Bank hereunder for all purposes of this
Agreement.  The Register shall be available for inspection by the Borrower, the
Guarantor, or any Bank at any reasonable time and from time to time upon
reasonable prior notice.

       (d)    Procedures.  Upon its receipt of an Assignment executed by a Bank
and an Eligible Assignee, together with the Note or Notes subject to such
assignment, the Agent shall, if such Assignment has been completed and is in
substantially the form of the attached Exhibit C, (i) accept such Assignment,
(ii) record the information contained therein in the Register, and (iii) give
prompt notice thereof to the Borrower and the Guarantor.  Within five Business
Days after its receipt of such notice, the Borrower, at its own expense, shall
execute and deliver to the Agent (x) in exchange for the surrendered A Note, a
new A Note to the order of such Eligible Assignee in an amount equal to the
Commitment assumed by it pursuant to such Assignment (without giving affect to
any B Reduction) and, if such assigning Bank has retained any Commitment
hereunder, a new A Note to the order of such Bank in an amount equal to the
Commitment retained by it hereunder (without giving affect to any B Reduction),
and (y) in exchange for any surrendered B Note, a new B Note to the order of
such Eligible Assignee in an amount equal to the B Advances assumed by it
pursuant to such Assignment and, if such assigning Bank has retained any B
Advances hereunder, a new B Note to the order of such Bank in any amount equal
to the B Advances retained by it hereunder.  Such new A Notes and B Notes shall
be dated the effective date of such Assignment and shall otherwise be in
substantially the form of the attached Exhibit A-1 or Exhibit A-2, as the case
may be.

       (e)    Participations.  Each Bank may sell participations to one or more
banks or other entities in or to all or a portion of its rights and obligations
under this Agreement (including, without limitation, all or a portion of its
Commitment, the Advances owing to it, and the Notes held by it); provided,
however, that (i) such Bank's obligations under this Agreement (including,
without limitation, its Commitment to the Borrower hereunder) shall remain
unchanged, (ii) such Bank shall remain solely responsible to the other parties
hereto for the performance of such obligations, (iii) such Bank shall remain
the holder of any such Notes for all purposes of this Agreement, (iv) the
Borrower, the Guarantor, the Agent, and the other Banks shall continue to deal
solely and directly with such Bank in connection with such Bank's rights and
obligations under this Agreement, (v) such Bank shall not require the
participant's consent to any matter under this Agreement, except for changes in
the principal amount of such Bank's Commitment, any Note payable to such Bank
in which the participant has an interest, or the aggregate Commitments,
reductions in fees or interest, the date any amount is due hereunder, or
extending the Termination Date or continuing the Commitment of such Bank
pursuant to Section 2.15 hereof, and (vi) such Bank shall give prompt





                                      -52-
<PAGE>   150
notice to the Borrower of each such participation sold by such Bank.  The
Borrower hereby agrees that participants shall have the same rights under
Sections 2.06(c), 2.10, 2.11, and 10.04 hereof as the Bank to the extent of
their respective participations.

       (f)  Assignment to Federal Reserve Bank.  Notwithstanding the
limitations set forth in paragraph (a) of this Section, any Bank may at any
time assign all or any portion of its rights under this Agreement or any Notes
payable to such Bank to a Federal Reserve Bank without the prior written
consent of the Borrower, the Guarantor, the Agent, the Co-Agents, or the
Arranger & Syndication Agent, provided that no such assignment shall release
such assigning Bank from any of its obligations hereunder or substitute any
such Federal Reserve Bank for such Bank as a party hereto.

       Section 10.07.  Governing Law.  This Agreement, the Notes and the other
Credit Documents shall be governed by, and construed in accordance with, the
laws of the State of Texas.

       Section 10.08.  Interest.

       (a)    It is the intention of the parties hereto that the Agent and each
Bank shall conform strictly to usury laws applicable to it, if any.
Accordingly, if the transactions with the Agent or any Bank contemplated hereby
would be usurious under applicable law, if any, then, in that event,
notwithstanding anything to the contrary in this Agreement, the Notes, or any
other agreement entered into in connection with or as security for this
Agreement or the Notes, it is agreed as follows:  (i) the aggregate of all
consideration which constitutes interest under applicable law that is
contracted for, taken, reserved, charged or received by the Agent or such Bank,
as the case may be, under this Agreement, the Notes, or under any other
agreement entered into in connection with or as security for this Agreement or
the Notes shall under no circumstances exceed the maximum amount allowed by
such applicable law and any excess shall be cancelled automatically and, if
theretofore paid, shall at the option of the Agent or such Bank, as the case
may be, be credited by the Agent or such Bank, as the case may be, on the
principal amount of the obligations owed to the Agent or such Bank, as the case
may be, by the Borrower or refunded by the Agent or such Bank, as the case may
be, to the Borrower, and (ii) in the event that the maturity of any Note or
other obligation payable to the Agent or such Bank, as the case may be, is
accelerated or in the event of any required or permitted prepayment, then such
consideration that constitutes interest under law applicable to the Agent or
such Bank, as the case may be, may never include more than the maximum amount
allowed by such applicable law and excess interest, if any, to the Agent or
such Bank, as the case may be, provided for in this Agreement or otherwise
shall be cancelled automatically as of the date of such acceleration or
prepayment and, if theretofore paid, shall, at the option of the Agent or such
Bank, as the case may be, be credited by the Agent or such Bank, as the case
may be, on the principal amount of the obligations owed to the Agent or such
Bank, as the case may be, by the Borrower or refunded by the Agent or such
Bank, as the case may be, to the Borrower.  To the extent that any Bank may be
subject to Texas law limiting the amount of interest





                                      -53-
<PAGE>   151
payable for its account, such Bank shall utilize the indicated (weekly) rate
ceiling from time to time in effect as provided in Article 5069-1.04 of the
Revised Civil Statutes of Texas, as amended.

       (b)    In the event that at any time the interest rate applicable to any
Advance made by any Bank would exceed the maximum non-usurious rate allowed by
applicable law, the rate of interest to accrue on the Advances by such Bank
shall be limited to the maximum non-usurious rate allowed by applicable law,
but shall accrue, to the extent permitted by law, on the principal amount of
the Advances made by such Bank from time to time outstanding, if any, at the
maximum non-usurious rate allowed by applicable law until the total amount of
interest accrued on the Advances made by such Bank equals the amount of
interest which would have accrued if the interest rates applicable to the
Advances pursuant to Article II had at all times been in effect.  In the event
that upon the final payment of the Advances made by any Bank and termination of
the Commitment of such Bank, the total amount of interest paid to such Bank
hereunder and under the Notes is less than the total amount of interest which
would have accrued if the interest rates applicable to such Advances pursuant
to Article II had at all times been in effect, then the Borrower agrees to pay
to such Bank, to the extent permitted by law, an amount equal to the excess of
(a) the lesser of (i) the amount of interest which would have accrued on such
Advances if the maximum non-usurious rate allowed by applicable law had at all
times been in effect or (ii) the amount of interest rates applicable to such
Advances pursuant to Article II had at all times been in effect over (b) the
amount of interest otherwise accrued on such Advances in accordance with this
Agreement.

       Section 10.09.  Execution in Counterparts.  This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.

       Section 10.10.  Survival of Agreements, Representations and Warranties,
Etc.  All warranties, representations and covenants made by the Borrower or the
Guarantor or any officer of the Borrower or the Guarantor herein or in any
certificate or other document delivered in connection with this Agreement shall
be considered to have been relied upon by the Banks and shall survive the
issuance and delivery of the Notes and the making of the Advances regardless of
any investigation.  The indemnities and other obligations of the Borrower
contained in this Agreement, and the indemnities by the Banks in favor of the
Agent and its officers, directors, employees and agents, will survive the
repayment of the Advances and the termination of this Agreement.

       Section 10.11.  Borrower's Right to Apply Deposits.  In the event that
any Bank is placed in receivership or enters a similar proceeding, the Borrower
may, to the full extent permitted by law, make any payment due to such Bank
hereunder, to the extent of finally collected unrestricted deposits of the
Borrower in U.S. dollars held by such Bank, by giving notice to the Agent and
such Bank directing such Bank to apply such deposits to such indebtedness.  If
the amount of such deposits is insufficient to pay such indebtedness then due
and owing in full, the Borrower shall pay the balance of such insufficiency in
accordance with this Agreement.





                                      -54-
<PAGE>   152
       Section 10.12.  Confidentiality.  Each Bank agrees that it will use best
efforts, to the extent not inconsistent with practical business requirements,
not to disclose without the prior consent of the Borrower and the Guarantor
(other than to employees, auditors, accountants, counsel or other professional
advisors of the Agent or any Bank or any Bank's Affiliate) any information with
respect to the Borrower or the Guarantor or their Subsidiaries which is
furnished pursuant to this Agreement and which (i) the Borrower or the
Guarantor in good faith consider to be confidential and (ii) is either clearly
marked confidential or is designated by the Borrower or the Guarantor to the
Agent or the Banks in writing as confidential, provided that any Bank may
disclose any such information (a) as has become generally available to the
public, (b) as may be required or appropriate in any report, statement or
testimony submitted to or required by any municipal, state or Federal
regulatory body having or claiming to have jurisdiction over such Bank or
submitted to or required by the Board of Governors of the Federal Reserve
System or the Federal Deposit Insurance Corporation or similar organizations
(whether in the United States or elsewhere) or their successors, (c) as may be
required or appropriate in response to any summons or subpoena in connection
with any litigation, (d) in order to comply with any law, order, regulation or
ruling applicable to such Bank, (e) to the prospective assignee or participant
in connection with any contemplated transfer of any of the Notes or any
interest therein by such Bank, provided that such prospective assignee or
participant executes an agreement with or for the benefit of the Borrower and
the Guarantor containing provisions substantially identical to those contained
in this Section 10.12.

       Section 10.13.  Binding Effect.  This Agreement shall become effective
when it shall have been executed by the Borrower, the Guarantor and the Agent,
and when each Bank listed on the signature pages hereof has delivered an
executed counterpart hereof to the Agent, has sent to the Agent a facsimile
copy of its signature hereon or has notified the Agent that such Bank has
executed this Agreement and thereafter shall be binding upon and inure to the
benefit of the Borrower, the Guarantor, the Agent, each Bank and their
respective successors and assigns, except that the Borrower and the Guarantor
shall not have the right to assign any of their respective rights hereunder or
any interest herein without the prior written consent of the Banks.

       SECTION 10.14.  ENTIRE AGREEMENT.  PURSUANT TO SECTION 26.02 OF THE
TEXAS BUSINESS AND COMMERCE CODE, A LOAN AGREEMENT IN WHICH THE AMOUNT INVOLVED
IN THE LOAN AGREEMENT EXCEEDS $50,000 IN VALUE IS NOT ENFORCEABLE UNLESS THE
LOAN AGREEMENT IS IN WRITING AND SIGNED BY THE PARTY TO BE BOUND OR THAT
PARTY'S AUTHORIZED REPRESENTATIVE.

       THE RIGHTS AND OBLIGATIONS OF THE PARTIES TO AN AGREEMENT SUBJECT TO THE
PRECEDING PARAGRAPH SHALL BE DETERMINED SOLELY FROM THE WRITTEN LOAN AGREEMENT,
AND ANY PRIOR ORAL AGREEMENTS BETWEEN THE PARTIES ARE SUPERSEDED BY AND MERGED
INTO THE LOAN AGREEMENT.  THIS WRITTEN AGREEMENT AND THE CREDIT DOCUMENTS, AS
DEFINED IN THIS AGREEMENT, REPRESENT THE FINAL AGREEMENT AMONG





                                      -55-
<PAGE>   153
THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS,
OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

       Section 10.15.  Severability.  In the event that any one or more of the
provisions contained in this Agreement or in any other Credit Document should
be held invalid, illegal or unenforceable in any respect, the validity,
legality and enforceability of the remaining provisions contained herein and
therein shall not in any way be affected or impaired thereby.

principal thereof, shall be recorded by the Bank and, prior to any transfer
hereof, endorsed on the grid attached hereto which is part of this Promissory
Note.

       This Promissory Note is one of the A Notes referred to in, and is
subject to and entitled to the benefits of, the U.S. $325,000,000 5-Year Credit

intent to accelerate, notice of acceleration and any other notice of any kind,

delay in exercising, any rights hereunder on the part of the holder hereof
shall operate as a waiver of such rights.

       This Promissory Note shall be governed by, and construed in accordance
with, the laws of the State of Texas (except that Tex. Rev. Civ. Stat. Ann.
Art. 5069, Ch. 15, which regulates certain revolving credit loan accounts,

                    [FORM OF OPINION OF GENERAL COUNSEL FOR
                        THE BORROWER AND THE GUARANTOR]


                               February 27, 1997


To each of the lenders parties to
  the Credit Agreement herein
  described and  to NationsBank
  of Texas, N.A., as Agent

Ladies and Gentlemen:

This opinion is furnished to you pursuant to Section 3.01 of the U.S.
$325,000,000 5-Year Credit Agreement dated as of February 27, 1995 (the "Credit
Agreement"), among Fina Oil and Chemical Company, as borrower (the "Borrower"),
Fina, Inc., as guarantor (the "Guarantor"), the banks parties thereto (the
"Banks"), CIBC Inc. and Texas Commerce Bank National Association, as Co-Agents,
NationsBanc Capital Markets, Inc., as Arranger & Syndication Agent, and
NationsBank of Texas, N.A., as Agent for the Banks.  Terms defined in the
Credit Agreement are used herein as therein defined.

       [Opinion format of rendering counsel to be supplied by such counsel.]

                                   Opinions:

       1.     Each of the Borrower and the Guarantor is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware.

       2.     Each of (i) the execution, delivery and performance by each of
the Borrower and the Guarantor of the Credit Agreement, (ii) the execution,
delivery and performance by the Borrower of the A Notes and the other Notes to
be executed by the Borrower, and (iii) the consummation of the transactions
contemplated by the Credit Agreement, are within the corporate powers of the
Borrower and the Guarantor, respectively, have been duly authorized by all
necessary corporate action, do not contravene (x) the Certificate of
Incorporation or the By-laws of the Borrower or the Guarantor, respectively, or
(y) any law, rule or regulation applicable to the Borrower or the Guarantor
(including, without limitation, Regulation X of the Board of Governors of the
Federal Reserve System) or (z) any contractual or legal restriction and will
not result in or require the creation or imposition of any Lien prohibited by
the Credit Agreement.  With respect to the Notes to be executed after the date
hereof by the Borrower, this
<PAGE>   174
February 27, 1997
Page 2



opinion is limited to laws, rules and regulations as in force and applied on
the date hereof, the Certificate of Incorporation and the Bylaws of the
Borrower, and restrictions in effect on the date hereof.  The Credit Agreement
has been duly executed and delivered by the Borrower and the Guarantor, and the
A Notes have been duly executed and delivered by the Borrower.

       3.     No authorization, approval or other action by, and no notice to
or filing with, any governmental authority or regulatory body is required for
the due execution, delivery and performance by the Borrower or the Guarantor of
the Credit Agreement, and (in the case of the Borrower) the respective Notes or
the consummation of the transactions contemplated by the Credit Agreement.

       4.     The A Notes executed by the Borrower constitute, and each Note
hereafter executed by the Borrower will constitute, a legal, valid and binding
obligation of the Borrower, enforceable against the Borrower in accordance with
its terms.  The Credit Agreement executed by the Borrower and the Guarantor
constitutes legal, valid and binding obligations of the Borrower and the
Guarantor, respectively, enforceable against the Borrower and the Guarantor in
accordance with its terms.

       5.     There are no pending or overtly threatened actions or proceedings
against the Borrower, the Guarantor or any of their respective Subsidiaries
before any court, governmental agency or arbitrator which purport to affect the
legality, validity, binding effect or enforceability of the Credit Agreement or
any of the Notes or which could reasonably be expected to have a materially
adverse effect upon the financial condition or operations of the Borrower and
its Subsidiaries taken as a whole, or the Guarantor and its Subsidiaries taken
as a whole.

       6.     Neither the Borrower nor the Guarantor is an "investment company"
or a company "controlled" by an "investment company" within the meaning of the
Investment Company Act of 1940, as amended.  Neither the Borrower nor the
Guarantor is a "holding company", or a "subsidiary company" of a "holding
company", or an "affiliate" of a "holding company" or of a "subsidiary company"
of a "holding company", or a "public utility" within the meaning of the Public
Utility Holding Company Act of 1935, as amended.

                  FORM OF OPINION OF SPECIAL COUNSEL TO AGENT


                               February 27, 1997


To each of the lenders parties
  to the Credit Agreement
  herein described and to
  NationsBank of Texas, N.A.,
  as Agent

Ladies and Gentlemen:

We have acted as special counsel to NationsBank of Texas, N.A., acting for
itself and as Agent, in connection with the preparation, execution and delivery
of the U.S. $325,000,000 5-Year Credit Agreement dated as of February 27, 1997
(the "Credit Agreement"), among Fina Oil and Chemical Company, as borrower (the
"Borrower"), Fina, Inc., as guarantor (the "Guarantor"), CIBC Inc. and Texas
Commerce Bank National Association, as Co-Agents, NationsBanc Capital Markets,
Inc., as Arranger & Syndication Agent, NationsBank of Texas, N.A., as agent
(the "Agent"), and each of you named as Banks thereunder.  Terms defined in the
Credit Agreement are used herein as therein defined.

In that connection, we have examined the following documents:

              (1)    counterparts of the Credit Agreement, executed by the
       Agent, the Borrower, and the Guarantor, respectively;

              (2)    the A Notes dated as of February 27, 1997 of the Borrower
       payable to the order of each Bank party to the Credit Agreement as of
       the date hereof (the "A Notes"); and

              (3)    the opinion dated February 27, 1997 of Cullen M. Godfrey,
       General Counsel for each of the Borrower and the Guarantor ("Opinion").

In our examination of the documents referred to above, we have assumed the
authenticity of all such documents submitted to us as originals, the
genuineness of all signatures and the conformity to the originals of all such
documents submitted to us as copies.  We have also assumed that each of the
Borrower, the Guarantor, the Banks and the Agent has duly executed and
delivered, with all necessary power and authority (corporate and otherwise),
the Credit
<PAGE>   176
February 27, 1997
Page 2



Agreement, that the Borrower has duly executed and delivered, with all
necessary power and authority (corporate and otherwise), the A Notes.  We have
also assumed that no Bank has requested that the Opinion required by Section
3.01(d) of the Credit Agreement contain any other matters not contained in the
form of opinion set forth as Exhibit D to the Credit Agreement.

Based upon the foregoing examination of documents and assumptions and upon such
other investigation as we have deemed necessary, we are of the opinion that the
A Notes and the Opinion, are substantially responsive to the requirements of
the Credit Agreement.

This opinion is solely for the benefit of the Banks, the Agent, their
respective successors, assigns, participants and other transferees and may be
relied upon only by such Persons.

                                           Very truly yours,



                                           Bracewell & Patterson, L.L.P.

                                             THROUGH AMENDMENT NO. 3

              AMERICAN PETROFINA, INCORPORATED

      EMPLOYEE NON-QUALIFIED STOCK OPTION PLAN (1979)


     Section 1.     Purpose.  It has been the policy of 
American Petrofina, Incorporated ("Company") since 1957 to 
promote the interests of the Company and its shareholders by 
providing a method whereby officers and other key employees 
of the Company and its subsidiaries may be encouraged to 
invest in the Company's Class A Common Stock and thereby 
increase their proprietary interest in its business, 
encourage them to remain in the employ of the Company and 
increase their personal interest in its continued success 
and progress.  The purpose of this Plan is to continue such 
policy.

    Section 2.      Administration.  (a)  A Committee of the 
Board of Directors of the Company ("Committee"), which shall 
be selected by the Board and none of whose members shall be 
eligible to receive options, shall have full power and 
authority, subject to such orders or resolutions not 
inconsistent with the provisions of the Plan as may from time 
to time be issued or adopted by the Board, to interpret the 
provisions and supervise the administration of the Plan.  
All determinations by the Committee shall be made by the 
affirmative vote of a majority of its members, but any 
determination reduced to writing and signed by all of the





<PAGE>   2
members shall be fully as effective as if it had been made 
by a majority vote at a meeting duly called and held.

    (b)  Each option shall be evidenced by an option 
agreement which shall contain such terms and conditions as may be 
approved by the Committee and shall be signed by an officer 
of the Company and the employee.

    (c)  Subject to any applicable provisions of the 
Company's By-laws, all decisions made by the Committee pursuant 
to the provisions of the Plan and related orders or resolutions 
of the Board shall be final, conclusive and binding on 
all persons, including the Company, shareholders, employees 
and optionees.

    Section 3.      Shares Subject to the Plan.  (a) The 
shares of Class A Common Stock to be delivered upon exercise 
of options granted under the Plan shall be made available, 
at the discretion of the Board of Directors, either from the 
authorized but unissued shares of the Company or from shares 
reacquired by the Company, including shares purchased in the 
open market.

    (b)  Subject to adjustments made pursuant to the 
provisions of paragraph (c) of this Section 3, the aggregate 
number of shares to be delivered upon exercise of all options 
which may be granted under this Plan shall not exceed 
250,000 shares.  If an option granted under this Plan shall 
expire or terminate for any reason during the term of the





<PAGE>   3
Plan, the shares subject to but not delivered under such 
option shall be available for other options under the Plan.

    (c)  In the event of a merger, reorganization, consolidation, 
recapitalization, stock dividend, or other change in 
corporate structure affecting the Company's Class A Common 
Stock, such adjustment shall be made in the aggregate number 
of shares subject to the Plan and the number and option 
price of shares subject to options granted under the Plan as 
may be determined to be appropriate by the Board of 
Directors upon recommendation by the Committee.

    Section 4.      Eligibility and Participation.  The 
employees eligible to receive options shall consist of 
salaried officers and other key employees of the Company and its 
subsidiaries (whether or not directors of the Company).  
Subject to the limitations of the Plan, the Committee shall 
select the employees to be granted options, determine the 
number and option price of the shares subject to each 
option, and determine the times when each option shall be 
granted and within which it may be exercised.  More than one 
option may be granted to the same employee.

    Section 5.      Option Period.  The maximum period 
during which each option may be exercised shall be fixed by 
the Committee at the time such option is granted, but such 
period in no event shall exceed ten years from the date the 
option is granted.





<PAGE>   4
    Section 6.      Option Price and Payment.  The price at 
which shares may be purchased upon exercise of a particular 
option shall be not less than 100 percent of the fair market 
value of such shares on the day such option is granted, as 
determined by the Committee.  For this purpose such fair 
market value shall be the average of the highest and lowest 
prices at which the Company's Class A Common Stock is traded 
on the American Stock Exchange or, if not so traded, the 
average of the closing bid and asked prices thereof on such 
Exchange as reported for the day the option is granted.

    Section 7.      Exercise of Options.   (a) Each option 
granted under this Plan may be exercised only after two 
years of continued employment by the Company or its 
subsidiaries immediately following the date the option is 
granted and, except in case of death, retirement and 
termination of employment as hereinafter provided, only during 
the continuance of the optionee's employment with the Company 
or one of its subsidiaries.  The times when optioned 
shares may be purchased and the number of shares which may 
be purchased at such times shall be fixed by the Committee 
and set forth in the option agreement.  Subject to the 
foregoing limitations and the terms and conditions of the 
option agreement, each option shall be exercisable at any 
time or from time to time, but no option may at any time be





<PAGE>   5
exercised in part with respect to fewer than twenty shares.

    (b)  The Company shall have no obligation to deliver 
shares pursuant to the exercise of any option, in whole or 
in part, until qualified for delivery under such laws and 
regulations as may be deemed by the Company to be applicable 
thereto and until payment in full of the option price 
therefor is received by the Company in cash or cash 
equivalent (or certificates representing shares of common 
stock of the company having a market value equal to the 
Option Price).  No optionee, or the legal representative, 
legatee, or distributee of any optionee, shall be or be 
deemed to be a holder of any shares subject to such option 
unless and until the certificate or certificates therefor 
have been issued.

    Section 8.      Federal Withholding Tax.  The Company 
shall collect a Federal Withholding Tax from the optionee 
when any option, other than an incentive stock option 
granted in accordance with Section 13 of the Plan, is 
exercised, in an amount equal to twenty percent (20%) of the 
difference between the option price and the fair market 
value of shares on the date of exercise of such option.

    Section 9.      Transferability of Options and Shares.  
A Non-Qualified Stock Option granted under the Plan may not 
be transferred except by will or by the laws of descent and
distribution and, during the lifetime of the employee to





<PAGE>   6
whom granted, may be exercised only by such employee.  The 
shares issued to an optionee pursuant to the exercise of an 
Incentive Stock Option granted under the Plan may not be 
assigned, transferred or alienated for a period of two (2) 
years from the date of the issuance of such shares to such 
optionee except by will or by the laws of descent and 
distribution, and the Committee shall affix to the stock 
certificate or certificates representing such shares an 
appropriate legend evidencing such restriction.

    Section 10.     Death, Retirement, and Termination of 
Employment.  Any option, the period of which has not 
theretofore expired, shall terminate at the time of the death of 
the employee to whom granted or of the termination for any 
reason of such employee's employment with the Company and 
its subsidiaries, and no shares may thereafter be delivered 
pursuant to such option, except that, subject to the 
condition that no option may be exercised in whole or in part 
after the expiration of the option period specified in the 
option agreement:

    (a)  After termination of employment due to disability 
or retirement under a retirement plan of the Company, unless 
the Committee elects to cancel such option because of actions 
of the employee deemed inimical to the best interests 
of the Company, an optionee may, within one year after the 
date of such termination, purchase from time to time some or 
at any time all of the shares with respect to which such





<PAGE>   7
optionee was entitled to exercise such option immediately 
prior to such termination, and

    (b)  After the death of any optionee while in active 
service or of any such disabled or retired optionee within 
the one-year period referred to in (a) above, the person or 
persons to whom such optionee's rights under the option are 
transferred by will or the laws of descent and distribution 
may, within one year after the date of such optionee's 
death, purchase from time to time some or at any time all of 
the shares with respect to which such optionee was entitled 
to exercise such option immediately prior to the death of the 
optionee.

    Section 11.     Amendments and Discontinuance.  The 
Board of Directors may amend, suspend, or discontinue the 
Plan, but may not, without the prior approval of the 
shareholders or pursuant to Section 3(c) above, make any 
amendment which operates (a) to abolish the Committee, change the 
qualification of its members, or withdraw the administration 
of the Plan from its supervision, (b) to make any material 
change in the class of eligible employees as defined in the 
Plan, (c) to increase the total number of shares for which 
options may be granted under the Plan, (d) to extend the 
terms of the Plan or the maximum option period, (e) to decrease 
the minimum option price, or (f) to permit adjustment





<PAGE>   8
or reductions of the price at which shares may be purchased 
under any option granted under the Plan.

    Section 12.     Effective Date.   The Plan shall become 
effective as of August 7, 1979, but all options granted 
prior to the Company's 1980 Annual Meeting of Shareholders 
shall be granted subject to approval of the Plan at that 
meeting.

    Section 13.     Incentive Stock Options.  Any option 
granted under the Plan may be designated by the Committee as 
an incentive stock option intended to qualify under Section 
422A of the Internal Revenue Code.  Any provision of the 
Plan to the contrary notwithstanding, (i) no incentive stock 
option shall be granted to any employee who, at the time 
such incentive stock option is granted, owns stock 
possessing more than 10 percent of the total combined voting 
power of all classes of stock of the Company or any 
affiliate unless the purchase price under such incentive stock 
option is at least 110 percent of the fair market value of 
the Company's Class A Common Stock at the date of grant and 
such incentive stock option is not exercisable after the 
expiration of five years from the date of its grant, (ii) no 
incentive stock option granted to any employee shall be 
exercisable while there is outstanding (within the meaning 
of Section 422A of the Internal Revenue Code) any incentive 
stock option which was previously granted under the Plan or





<PAGE>   9
any other such plan to such employee to purchase shares of 
Class A Common Stock (or any other stock of the Company) or 
the stock of an affiliate (or any predecessor corporation of 
the Company or an affiliate) and (iii) the sum of the fair 
market value (determined as of the time an incentive stock 
option is granted) of the Class A Common Stock for which an 
employee may be granted incentive stock options under the 
Plan and the fair market value (determined as of the time 
such incentive stock options are granted) of the stock for 
which such employee may be granted incentive stock options 
under all other such plans of the Company or an affiliate 
shall not, in any calendar year, exceed $100,000 plus any 
"unused limit carryover" as provided in Section 422A of the 
Internal Revenue Code.  Unless otherwise determined by the 
Committee in the case of stock of the Company or an affiliate 
which is not listed or admitted to trading on the 
American Stock Exchange, the term "fair market value" shall 
have the meaning set forth in Section 6 hereof.  As used 
herein, the term "affiliate" means any parent or subsidiary 
corporation of the Company within the meaning of Section 
425(e) and (f) of the Internal Revenue Code.

                          INDEPENDENT AUDITORS' REPORT
 
The Plan Committee
Amdel Inc. Employee Investment Plan:
 
     We have audited the accompanying statements of net assets available for
plan benefits of the Amdel Inc. Employee Investment Plan as of December 31, 1995
and 1994 and the related statements of changes in net assets available for plan
benefits for the years then ended. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the net assets available for plan benefits of the
Amdel Inc. Employee Investment Plan as of December 31, 1995 and 1994, and the
changes in net assets available for plan benefits for the years then ended in
conformity with generally accepted accounting principles.
 
     Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules of assets held
for investment and reportable transactions are presented for the purpose of
additional analysis and are not a required part of the basic financial
statements but are supplementary information required by the Department of
Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. The Fund Information in the statements
of net assets available for plan benefits and the statements of changes in net
assets available for plan benefits is presented for purposes of additional
analysis rather than to present the net assets available for plan benefits and
changes in net assets for plan benefits of each Fund. The supplemental schedules
and Fund Information have been subjected to the auditing procedures applied in
the audits of the basic financial statements and, in our opinion, are fairly

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1995 AND 1994
 
(1)  GENERAL AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  (a)  General
 
     The Amdel Inc. Employee Investment Plan (the Plan) operates for the benefit
of certain employees of American Petrofina Pipe Line Co. and certain employees
of Fina Oil and Chemical Company (FOCC), both of which are wholly-owned
subsidiaries of FINA, Inc. and are hereafter referred to as "employing
companies."
 
     The Plan is a defined contribution plan covering certain full-time
employees of the employing companies who have completed six months of service.
The Plan is subject to the provisions of the Employee Retirement Income Security
Act of 1974, as amended (ERISA). The following description of the Plan reflects
all Plan amendments and is provided for general purposes only. Participants
should refer to the Plan document for more complete information.
 
     The Plan is administered by the Pension Committee appointed by and acting
on behalf of the Board of Directors of FOCC. Pursuant to the Plan's trust
agreement, an independent trustee (Trustee) maintains custody of the Plan's
assets. The Boston Safe Deposit and Trust Company serves as the independent
trustee.
 
  (b)  Basis of Presentation
 
     The accompanying financial statements of the Plan have been prepared on an
accrual basis using fair values for investments. The fair values of investments
are based on closing market quotations or listed redeemable values. Security
transactions are recorded on a trade date basis.
 
  (c)  Expenses Relating to Investment Securities
 
     Expenses relating to the purchase or sale of investment securities are
added to the cost or deducted from the proceeds, respectively.
 
  (d)  Expenses of Administering the Plan
 
     All costs and expenses incurred in administering the Plan, including the
fees and expenses of the Trustee, the fees of its counsel and other
administrative expenses, are the responsibility of the employing companies
through June 30, 1994. Beginning July 1, 1994 all external costs and expenses
incurred in administering the Plan are the responsibility of the Plan's
participants.
 
  (e)  Contributions
 
     Participants may elect to contribute up to 10% of their basic compensation
to the Plan. The employing company will contribute an amount equal to the lesser
of the amount contributed by the participant or 5% of the participant's basic
compensation. Employing company contributions are reduced by participants'
forfeitures.
 
  (f)  Investment Program and Vesting
 
     The Trustee of the Plan by law retains responsibility for the investments
of the Plan. Consistent with the fiduciary standards of ERISA, safeguards are
adhered to in protecting the interests of Plan participants and their
beneficiaries.
 
     A participant may direct the proportions of his or her allotments, employer
contributions, and any earnings received by the Trustee for his or her account
into a money market fund, government securities fund, or the Class A common
stock of FINA, Inc. In the absence of direction, all amounts will be held in
cash

without interest. Participants become completely vested in contributions of the
employing companies upon five years of service with the company.
 
     A description of such rights and provisions and an explanation of the
treatment of forfeitures and other matters are contained in the Plan document.
 
     Participation in each investment option at December 31, 1995 and 1994 is
presented below. The sum of participation by investment option is greater than
the total number of Plan participants because participation is allowed in more
than one option.
 
     A summary of participants by investment options follows:

  (g) Withdrawals
 
     A participant may withdraw securities and cash attributable to his or her
allotments at any time. Withdrawal of any part of the amounts attributable to
the employing companies' contributions, except on retirement under the Amdel
Inc. Noncontributory Retirement Plan, death or disability, is contingent upon
completion of five years of service. Any amounts not eligible for withdrawal due
to employee termination are forfeited and applied to reduce subsequent employing
companies' contributions. In certain circumstances, amounts forfeited may be
restored to terminated employees who are subsequently reemployed provided they
repay the amount previously withdrawn or distributed.
 
     Withdrawals in cash and in kind in the accompanying financial statements
represent the fair value of the assets at date of distribution.
 
  (h)  Form 5500 Reconciliation
 
     The net assets available for plan benefits and withdrawals reported in the
Plan's Form 5500 are different from the corresponding amount reported in the
accompanying financial statements by $786,289 and ($33,735), respectively, as of
and for the year ended December 31, 1995 and $752,554 and $47,611, respectively,
as of and for the year ended December 31, 1994. These differences relate to the
classification of withdrawals currently payable to participants.
 
  (i)  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the plan administrator to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
(2)  FEDERAL INCOME TAXES
 
     The Plan has obtained from the Internal Revenue Service a determination
letter dated August 18, 1995 indicating that the Plan qualifies under the
provisions of Section 401(a) of the Internal Revenue Code and, accordingly, is
exempt from Federal income taxes under Section 501(a). The United States Federal
income tax status of the participants with respect to their contributions to the
Plan is described in information submitted to the participants and subject to
certain limitations.

(3)  PLAN TERMINATION
 
     Although they have not expressed any intent to do so, the employing
companies have the right under the Plan to discontinue their contributions at
any time and to terminate the Plan subject to the provisions of ERISA. In the
event of Plan termination, participants will become 100% vested in their
accounts.

                          INDEPENDENT AUDITORS' REPORT
 
The Plan Committee
FINA Capital Accumulation Plan:
 
     We have audited the accompanying statements of net assets available for
plan benefits of the FINA Capital Accumulation Plan as of December 31, 1995 and
1994, and the related statements of changes in net assets available for plan
benefits for the years then ended. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the net assets available for plan benefits of the FINA
Capital Accumulation Plan as of December 31, 1995 and 1994, and the changes in
net assets available for plan benefits for the years then ended in conformity
with generally accepted accounting principles.
 
     Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules of assets held
for investment and reportable transactions are presented for the purpose of
additional analysis and are not a required part of the basic financial
statements but are supplementary information required by the Department of
Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. The Fund Information in the statements
of net assets available for plan benefits and the statements of changes in net
assets available for plan benefits is presented for purposes of additional
analysis rather than to present the net assets available for plan benefits and
changes in net assets available for plan benefits of each Fund. The supplemental
schedules and Fund Information have been subjected to the auditing procedures
applied in the audits of the basic financial statements and, in our opinion, are
fairly stated in all material respects in relation to the basic financial
statements taken as a whole.

Employees who have completed one year of service are eligible to participate in
the Plan; provided, however, that no employee may become a participant if the
employee is a member of a collective bargaining unit, the recognized
representative of which has not agreed to participation in the Plan by members
of such unit.
 
     The Plan is a defined contribution plan and is subject to the provisions of
the Employee Retirement Income Security Act of 1974, as amended (ERISA). The
following description of the Plan is provided for general purposes only.
Participants should refer to the Plan document for more complete information.
 
     The Plan is administered by the Pension Committee appointed by and acting
on behalf of the Board of Directors of the Company. Pursuant to the Plan's trust
agreement, an independent trustee (Trustee) maintains custody of the Plan's
assets. The Boston Safe Deposit and Trust Company serves as the independent
trustee.
 
  (b)  Basis of Presentation
 
     The accompanying financial statements have been prepared on an accrual
basis using fair values for investments. The fair values of investments are
based on closing market quotations or listed redeemable values. Security
transactions are recorded on a trade date basis.
 
  (c)  Expenses Relating to Investment Securities
 
     Expenses relating to the purchase or sale of investment securities are
added to the cost or deducted from the proceeds, respectively.
 
  (d)  Expenses of Administering the Plan
 
     All costs and expenses incurred in administering the Plan, including the
fees and expenses of the Trustee, the fees of its counsel and other
administrative expenses, were the responsibility of the employing companies
through June 30, 1994. Beginning July 1, 1994 all external costs and expenses
incurred in administering the Plan are the responsibility of the Plan
participants.
 
  (e)  Contributions
 
     Participants may elect to contribute up to 5% of their basic compensation
on an after-tax basis (Thrift Contribution), up to 10% on a pre-tax basis
(Deferred Compensation Contribution), or a combination of pre-tax and after-tax
contributions not exceeding 10% of their basic compensation. If a participant
elects to make a Deferred Compensation Contribution, the participant must enter
into a basic compensation reduction agreement authorizing the employing company
to make such contribution on the participant's behalf.
 
     For each participant, an employing company will contribute an amount equal
to the lesser of the aggregate Thrift and Deferred Compensation Contributions
for the pay period or 6% pre-tax of the participant's basic compensation for the
pay period (Matching Contribution). Matching Contributions are reduced by
participants' forfeitures.
 
     Thrift and Deferred Compensation Contributions are paid to the Trustee in
cash and Matching Contributions are paid to the Trustee in cash or the Company's
Class A common stock.

  (f)  Investment Program and Vesting
 
     Participants may direct the investment of their Thrift and Deferred
Compensation Contributions into a money market fund, U.S. debt index fund,
balanced fund, equity index fund, global equity fund, the Company's Class A
common stock or PetroFina S.A. common stock; and the investment of the Matching
Contributions into the Company's Class A common stock or Petrofina S.A. common
stock. Participants become completely vested in contributions of the employing
companies upon five years of service with the employing companies.
 
     A description of rights and provisions and an explanation of the treatment
of withdrawals, forfeitures and other matters are contained in the Plan
document.
 
     Participation in each investment option at December 31, 1995 and 1994 is
presented below. The sum of participation by investment option is greater than
the total number of Plan participants making contributions because participation
is allowed in more than one investment option.
 
     A summary of participants by investment options follows:

  (g)  Loan Option
 
     A participant may borrow from his or her Participant Deferred Account an
amount which, when added to the greater of the total outstanding balance of all
other loans to such Participant from the Plan or the highest outstanding balance
of all such loans for the one-year period ending the day before the date of the
loan, does not exceed up to one-half of the first $100,000 of such participant's
vested interest under the Plan, or the amount allowed under Section 72(p) of the
Internal Revenue Code. Any such loan made to a participant shall be evidenced by
a promissory note payable to the Trustee, shall bear a reasonable rate of
interest, shall be secured by the borrowing participant's vested interest under
the Plan and shall be repayable within five years; provided, however, that if
such loan is to be used to acquire or construct any dwelling unit which within a
reasonable time is to be used as a principal residence of the participant, the
Committee may direct the Trustee to make such loan repayable over such period
greater than five years. No withdrawal pursuant to any of the withdrawal
provisions of the Plan may be made by a participant to whom a loan is
outstanding from the Plan unless the Committee is satisfied that such loan will
remain nontaxable and fully secured by the withdrawing participant's vested
interest under the Plan following such withdrawal.
 
  (h)  Form 5500 Reconciliation
 
     The net assets available for plan benefits and withdrawals reported in the
Plan's 1995 and 1994 Form 5500's are different from the corresponding amounts
reported in the accompanying financial statements by $1,525,597 and ($613,380),
respectively, as of and for the year ended December 31, 1995 and $912,217 and
$665,945, respectively, as of and for the year ended December 31, 1994. These
differences relate to the classification of withdrawals currently payable to
participants.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  (i)  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the plan administrator to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
(2)  FEDERAL INCOME TAXES
 
     The Plan has obtained from the Internal Revenue Service a determination
letter dated March 19, 1996 indicating that the Plan qualifies under the
provision of Sections 401(a) and 401(k) of the Internal Revenue Code and,
accordingly, is exempt from Federal income taxes under Section 501(a). The
United States Federal income tax status of the participants with respect to
their contributions to the Plan is described in information submitted to the
participants and, subject to certain limitations, such contributions are tax
deferred.
 
(3)  PLAN TERMINATION
 
     Although they have not expressed any intent to do so, the employing
companies have the right under the Plan to discontinue their contributions at
any time and to terminate the Plan subject to the provisions of ERISA. In the
event of Plan termination, participants will become 100% vested in their
accounts.

May 20, 1986

Mr. Ronald W. Haddock
8306 Acupulco Cove Court
Humble, TX  77338

Dear Ron:

In consideration of your decision to join American Petrofina, Incorporated
(API), API agrees to provide you, upon retirement from the active service of
API at age 55 or later, with supplemental retirement benefits as determined in
the following manner:

Your primary retirement benefit will equal 1.6% of your Final Average Earnings
(includes basic salary and paid bonuses) that you receive from API over the 36
consecutive months out of the most recent 120 months immediately prior to
retirement during which such earnings are the highest. Final Average Earnings
shall then be multiplied by the number of completed years and months of service
from June 11, 1963 to the date of your retirement from API, and then reduced by
the lesser of (i) 1-1/2% of your Old Age Social Security benefit for such
completed years and months of service or (ii) 50% of your Old Age Social
Security benefit. If your retirement is prior to age 60,  the retirement
benefit amount will be reduced 5/12% for each month that your retirement
precedes age 60. This retirement benefit amount will be payable as a 5 year and
life annuity.

Your retirement benefit, as determined in the preceding paragraph, shall be
reduced by the following three amounts:

The first amount will equal your vested deferred monthly 5 year certain and
life annuity from the Exxon Corporation plan payable from your retirement date.

The second amount will equal your monthly 5 year certain and life annuity from
the Pension Plan for employees of American Petrofina, Incorporated and Certain
Subsidiaries payable from your retirement date.




<PAGE>   2
Mr. Ronald W. Haddock

Page Two


The third amount will equal your monthly 5 year certain and life annuity from
the Excess Benefit Plan of American Petrofina, Incorporated and Certain
Subsidiaries payable from your retirement date.

Such supplemental retirement benefits may be converted into any of the optional
forms of benefit then permitted under the Pension Plan for employees of API,
using the actuarial equivalence factor applicable under that plan.

As we discussed, such supplemental retirement benefits will not be funded in
advance but will be considered as general obligations of API.

If you find the foregoing to be satisfactory to you, please so indicate in the
spaces provided below. Return one executed copy to me and retain one copy for
your files.

Sincerely,

   /s/

ACCEPTED AND AGREED this  29 day of May , 1986.

                          INTEROFFICE CORRESPONDENCE

                       THIS MEMORANDUM CONSTITUTES THE
                      AMENDMENT TO THE LETTER OF 5/20/86

Date:   December 16, 1993       Subject:   Tax Avoidance by Vesting--
                                           Ron W. Haddock's SERP
From:   Bill H. Bonnett

To:     Paul D. Meek

In order to keep the Company from paying $15,000 in FICA-Medicare taxes and an
equal match by the employee, I recommend a December 1, 1993 vesting of the
Supplemental Executive Retirement Plan (SERP) benefits outlined in the
employment contract you signed for Ron Haddock. This is a result of the Tax
Reform Act (OBRA '93) provision effective January 1, 1994, which requires a
FICA-Medicare tax of 1.45% on past accruals for SERP's at  the point of
vesting. This tax can be avoided if the benefit is vested before January 1,
1994.

When Ron was hired he received an individual employment contract which provided
a supplemental benefit to "keep him whole" with the Exxon equivalent benefit.
In the agreement (see attached) the benefit will vest when age 55 is reached
(7/95). There is no hidden cost to accelerate the vesting of the benefits as
long as Ron remains with FINA until at least age 55.

Your approval of this amendment to the employment contract is respectfully
requested. The attached E-mail form Mike Godfrey confirms approval by our
outside directors and Ron has also received approval from Francois Cornelis.



                                                     /s/

Contributions in cash and in Shares and Shares purchased 
by the Trustee using Company Contributions in cash shall 
be transferred to the Trust Fund prior to or as soon as

46(a)(2)(B), exceeds the limitations on allowable tax 
credits of Internal Revenue Code Section 46(a)(3), then
    
              (i)  that portion of the Shares allocable         
    to investment credit carrybacks of such excess credit       
    shall be transferred to the Trust Fund within the time      
    prescribed in Section 3.2 above for the Company             
    Contribution for the unused credit year, as defined         
    in Internal Revenue Code Section 46(b), and                 
    
              (ii) that portion of Shares allocable to          
    investment credit carryovers of such excess credit          
    shall be transferred to the Trust Fund within the           
    time prescribed in Section 3.2 above for the Year to        
    which such portion is carried over.                         

         3.3  Valuation of Share Contributions.  For 
purposes of Section 3.1 above, Company Contributions in 
Shares shall be valued (i) by taking the average of 
closing sale prices of the Class A Shares, as reported

trading days immediately preceding the date on which the 
Company's Federal income tax return is filed for the Year 
with respect to which such Company Contributions are




                                        
                                      
<PAGE>   16
made, or (ii) in the case of Class B Shares, not listed  
on a national exchange, at the value, as determined in    
(i) above, of the same number of Class A Shares.

         3.4  Initial Plan Qualification. 
Notwithstanding anything contained herein to the  
contrary, if an application for a determination that the 
Plan satisfies the requirements of Sections 301(d) and 
301(e) of the Tax Reduction Act and Internal Revenue Code 
Section 401(a) is filed with the Internal Revenue Service 
not later than 90 days following the date on which the 
Company's tax credit under Internal Revenue Code Section 
38 for 1976 with respect to the Plan is allowed, and if 
such determination is not issued, then all Company 
Contributions made to the Trust Fund may be returned to 
the Company and the Participating Companies within 12 
months after the date on which the Internal Revenue 
Service issues notice to the Company that the Plan does 
not satisfy the foregoing requirements or otherwise 
advises the Company that it refuses to issue a favorable 
determination.

Year, commencing with 1977, each Participant may elect   
to make voluntary Employee Contributions in cash to the 
Trust Fund in an amount not less than 2% nor more than  
10% of the Participant's Compensation for the Year; 
provided, that such Participant must designate in writing 
that his Employee Contributions for that Year shall be 
available as Matching Employee Contributions.  Such 
Employee Contributions shall be made by payroll  
deductions or such other means as the Committee may 
prescribe.  Employee Contributions shall be accumulated 
and held by the Company, without interest, and shall be 
transferred to the Trust Fund at the end of each quarter 
of the Year.

         (b)  Employee Contributions shall be used by the 
Trustee to purchase Shares as soon as reasonably 
practicable following the date on which such Employee 
Contributions are received by the Trustee.  Class A  
Shares and Class B Shares so purchased shall be acquired 
by the Trustee in a ratio, at the date of any acquisition 
of such Shares, substantially equal to the proportion  
that the fair market value of all outstanding Class A 
Shares bears to the fair market value of all outstanding




                                        
                                      
<PAGE>   18
Class B Shares, in both cases excluding all such Shares 
held by the Trust Fund.  For this purpose, Class B Shares 
shall be valued at the same fair market value as the same 
number of Class A Shares.

         3.6  Additional Investment Credit Recapture.
(a) Except as otherwise provided in Section 3.6(b) (iii) 
below, if the amount of any additional investment credit 
determined under Internal Revenue Code Section  
46(a)(2)(B) is recaptured or redetermined in accordance 
with the provisions of said Internal Revenue Code, then 
the Company Contributions attributable thereto which have 
been transferred to the Trust Fund shall remain in the 
Trust Fund and shall continue to be allocated to 
Participants in the Plan.

         (b)  If any such credit is so recaptured, then:

              (i)   the Company or any Participating 
    Company may reduce the amount of its Company           
    Contribution for the Year in which recapture occurs    
    or any succeeding Years by the portion of the amount   
    so recaptured which is attributable to its respective  
    Company Contributions to the Trust Fund, or            




                                        
                                      
<PAGE>   19
              (ii) the Company or any Participating          
    Company may deduct said portion for Federal income  tax      
    purposes, subject to the limitations of Internal Revenue     
    Code Section 404, or                                         
                                                                 
              (iii) the Company or any Participating         
    Company may withdraw from the Trust Fund an amount           
    attributable to Company Contributions which is not           
    in excess of such portion which is recaptured, on            
    condition that (A) while subject to withdrawal               
    because of recapture, such amounts are segregated            
    from other Trust Fund assets, and (B) separate               
    accounts are maintained for Participants on whose            
    behalf said amounts have been allocated.  For this           
    purpose, Shares to be withdrawn from the Trust Fund          
    shall be valued at their fair market value at the            
    date of withdrawal.  Shares, dividends and other             
    assets in the Trust Fund attributable to Employee            
    Contributions may not be withdrawn under this Section        
    3.6(b)(iii).                                                 

         (c)  If the amount of the credit claimed by the 
Company or a Participating Company for any Year under 
Internal Revenue Code Section 38 is reduced because of    
a final redetermination of Federal income tax and Company




                                        
                                      
<PAGE>   20
Contributions were made for such Year, then either:

               (i)  the Company or any Participating 
    Company may reduce the amount of its Company           
    Contribution for the Year in which such                
    redetermination becomes final or any succeeding Year   
    by the portion of the amount of such reduction in the  
    credit or increase in tax which is attributable to     
    such Company Contributions, or                         

              (ii)  the Company or any Participating 
    Company may deduct such portion for Federal income tax       
    purposes, subject to the limitations of Internal             
    Revenue Code Section 404.                                    

SECTION 4.    Allocation of Shares to Participants.


         4.1   Proportionate Allocation.  (a)  All Shares 
directly attributable to Company Contributions which may 
be made without regard to any Matching Employee 
Contributions for any Year, as determined under Internal 
Revenue Code Section 46(a)(2)(B)(i), shall be allocated 
(to the nearest 1/100 of a Share) as of the end of such 
Year to the account of each Participant who completed at 
least 1,000 Hours of Service while a Participant during 
such Year in an amount which bears substantially the same




                                        
                                      
<PAGE>   21
proportion to the amount of all such Shares allocated for 
such Year to all Participants as the amount of such 
Participant's Compensation while a Participant for the 
Year (not in excess of $100,000) bears to the  
Compensation paid to all such Participants, while 
Participants, during that Year (disregarding each 
Participant's Compensation in excess of $100,000).

         (b)  All Shares directly attributable to Company 
Contributions which may be made only to match Matching 
Employee Contributions for the Year, as determined under 
Internal Revenue Code Section 46(a)(2)(B)(ii), shall be 
allocated as of the end of such Year to the account of 
each Participant in an amount equal to such Participant's 
share of the Matching Employee Contributions to the Trust 
Fund for such Year.

         (c)  All Shares purchased with Employee 
Contributions shall be allocated, as soon as reasonably 
practicable after they are purchased by the Trustee, to 
the accounts of the Participants who made such Employee 
Contributions.




                                        
                                      
<PAGE>   22
         (d) All Class A Shares and Class B Shares 
allocated to Participants' accounts under this Section  
4.1 shall be so allocated in the ratio, at the date of 
acquisition of such Shares by the Trustee, as set forth  
in Section 3.5(b) above.

         4.2  Limitations on Allocations.  (a) The total 
"annual addition", as defined below, allocated to any 
Participant's account during any Year shall not exceed  
the lesser of:

              (i)   the sum of (A) $26,825, adjusted for 
    each Year to take into account any cost-of-living       
    increase provided for that Year under Section 415(d)    
    of the Internal Revenue Code, plus (B) the lesser of    
    $26,825, as so adjusted, or the amount of the Company   
    Contributions for the Year, or                          

              (ii)  25% of the Participant's Compensation 
    for the preceding Year.

For purposes of this Section 4.2, the "annual addition" 
for any Year shall mean the sum of (1) the value of  
Shares directly attributable to Company Contributions and 
(2) the lesser of (A) the amount of the Participant's 
Employee Contributions for the Year in excess of 6% of




                                        
                                      
<PAGE>   23
his Compensation for such Year or (B) one-half of his 
Employee Contributions for such Year.

         (b)  For purposes of the computation of the 
limitation in Section 4.2(a) above, the amount referred  
to in Section 4.2(a)(i)(B) above shall be deemed to be 
zero if more than one-third of the Shares directly 
attributable to Company Contributions for that Year are 
allocated to the group of Participants consisting of 
officers of the Company, shareholders owning more than  
10% of the Company's Shares (determined under Internal 
Revenue Code Section 415(c)(6)(a)(iv)) and Participants 
whose Compensation for the Year exceeds an amount equal  
to twice $26,825, adjusted as described above.

         (c)  Notwithstanding the foregoing, in any case 
in which an individual is a Participant in the Plan and   
a participant in a defined benefit plan maintained by the 
Company or a Participating Company, the sum of such 
individual's "defined benefit plan fraction" and his 
"defined contribution plan fraction" for any Year, as 
defined in Internal Revenue Code Section 415(e), may not 
exceed 1.4.  The otherwise permissible "annual additions" 
to any such Participant under the Plan may be reduced to 
the extent necessary, as determined by the Committee, to




                                        
                                      
<PAGE>   24
prevent disqualification of the Plan, or of any other tax- 
qualified plan of deferred compensation maintained by the 
Company or a Participating Company in which such 
Participant is a member, under the 1.4 limitation imposed 
by Internal Revenue Code Section 415(e).  The Committee 
shall advise affected Participants of any additional 
limitation on "annual additions" required by the  
preceding sentences.

         4.3  Reallocation of Shares.  To the extent that 
any Shares directly attributable to Company Contributions 
cannot be allocated for any Year to a Participant's 
account because of the limitations contained in Section 
4.2 above, such Shares shall be proportionately 
reallocated for that Year under Section 4.1 to the 
accounts of other Participants.  If the amount of such 
Shares for any Year exceeds the amount which can be 
allocated under Section 4.2 and this Section 4.3 for that 
Year, such Shares shall be held in an unallocated account 
in the Trust Fund and shall be allocated proportionately 
under Section 4.1 for the next following Year.

SECTION 5.  Dividends.

         5.1  Reinvestment of Dividends.  Except as may 
otherwise be directed by the Committee or otherwise be 
provided in the Plan, all dividends paid on Shares held  
in the Trust Fund shall be used by the Trustee to  
purchase Class A Shares.  Such additional Class A Shares 
purchased with dividends on Shares allocated to a 
Participant's account shall be allocated to such 
Participant in the same proportion as the number of  
Shares (including fractional Shares) which were credited 
to such Participant's account immediately prior to the 
record date of the dividend bears to the total number of 
Shares (including fractional Shares) then credited to all 
such accounts.  Except as provided in Section 9.1(a) 
below, additional Class A Shares purchased with dividends 
and allocated to a Participant's account shall be 
distributed from such account at the same time and manner 
as are the Shares with respect to which said dividends 
were allocated.  Such additional Class A Shares purchased 
with dividends on Shares not allocated to a Participant's 
account shall be held with such unallocated Shares and 
allocated or otherwise distributed or withdrawn from the 
Trust Fund at the same time and manner as are said

Shares.

SECTION 6.    Voting Rights.

         6.1  Voting by Participants.  Each Participant shall be entitled to 
direct the Trustee as to the manner in which any rights--including but not 
limited to voting rights, subscription rights and conversion privileges--with 
respect to any Shares allocated to such Participant's account are to be 
exercised.  For this purpose, the Committee shall notify each Participant of 
each annual or special meeting of the shareholders of the Company and of any 
other occasion for the exercise of voting or other rights by such shareholders 
not later than the date, prior to such meeting or other occasion, on which the 
Company so notifies its other shareholders. The notification shall include a 
copy of any proxy solicitation material and any other information which the 
Company distributes to shareholders regarding the exercise of voting or other 
rights, together with a form requesting instructions to the Trustee as to how 
the Participant's rights are to be exercised.  The Committee shall tabulate and 
certify to the Trustee the instructions received, and the Trustee shall vote or 
otherwise exercise rights with respect to Shares as

the Company may withhold from the amount of the total 
Company Contribution for 1976 so much of the amounts paid 
or incurred in connection with the establishment of the 
Plan as does not exceed the sum of (i) 10% of the first 
$100,000 of such Company Contribution for 1976 and (ii)

other than from Shares purchased with Employee 
Contributions.

<PAGE>   34
         (b)  In case of hardship, a Participant or any 
beneficiary designated by a deceased Participant may so 
apply for the immediate distribution of all or any whole 
number of such Shares, not otherwise distributable from 
the Trust Fund, except that no Shares contributed to the 
Trust Fund as Company Contributions or purchased with

determination shall be final and binding.  For the 
purposes of this Section 9.7, (i) disability shall mean 
incapacity (whether temporary or permanent) from gainful

may be, shall instruct the Trustee in writing either to 
"put" such Class B Shares to the Company for cash or to 
exchange such Shares with the Company for Class A Shares 
on a Share-for-Share basis.  If the "put" is elected, the 
value of the Class B Shares shall be deemed to be equal  
to the fair market value of the same number of Class A 
Shares, determined by taking the average of closing sale 
prices of the Class A Shares, as reported-by the  
composite tape for securities listed on the American  
Stock Exchange, Inc., for the 20 consecutive trading days 
immediately preceding the date on which such "put" is 
exercised.  Following such "put" or exchange, as the case 
may be, the Trustee shall distribute the assets in the 
Participant's account in accordance with the terms of the

enter into a Trust Agreement which shall contain such 
provisions as shall render it impossible for any part of

         11.4  Procedure and Performance of Fiduciary 
Duties.


              (a) The members of the Committee shall  
    elect one of their number as Chairman and shall elect    
    a Secretary who may, but need not, be a member of the    
    Committee; may appoint from their number such            
    committees with such powers as they shall determine;     
    may authorize one or more of their number or any         
    agent to execute or deliver any instrument in their      
    behalf, and may employ such counsel and agents as        
    they may require in carrying out the provisions of       
    the Plan.                                                
          
              (b) The Fiduciary Responsibilities of the 
    Committee may be allocated among its members or     
    delegated to persons who are not members of the     
    Committee; provided, however, that in order to be   
    effective such allocation or delegation of duties   




                                        
                                      
<PAGE>   40
    must (i) be made by a resolution of the Committee         
    unanimously adopted by the members thereof present        
    at a meeting of the Committee at which a quorum is        
    present, (ii) be specifically accepted in writing by      
    the person or persons to whom such duties are             
    allocated or delegated and (iii) be approved by the       
    Board of Directors.  Upon an allocation or delegation     
    of Fiduciary Responsibilities, the person or persons      
    to whom such Fiduciary Responsibilities are allocated     
    or delegated shall be solely responsible for the          
    performance of such Fiduciary Responsibilities, and       
    the other members of the Committee shall not in any       
    respect be responsible for the performance of such        
    Fiduciary Responsibilities, except as provided in the     
    following sentences.  The Committee shall, at least       
    annually, review the performance of any person or         
    persons to whom any Fiduciary Responsibility has been     
    allocated or delegated.  A review may be instigated       
    at the request of any member of the Committee.  In        
    the event such review is satisfactory to the              
    Committee, the Committee may by resolution,               
    unanimously approved by the voting members,               
    specifically approve the performance of such person       
    during the past term and extend for an additional         




                                        
                                      
<PAGE>   41
    twelve-month period the allocation or delegation of      
    Fiduciary Responsibilities to such person or persons.    
    The Committee shall report to the Board of Directors     
    any such resolution and the extension will be            
    effective unless the Board of Directors disapproves      
    it.  In the event the Committee does not adopt an        
    extension resolution, the allocation or delegation       
    shall become immediately null and void and such          
    Fiduciary Responsibilities shall revert immediately      
    to the committee.  The Committee shall perform its       
    allocation and delegation functions in the same          
    manner as it performs all of its other Fiduciary         
    Responsibilities pursuant to paragraph (c) below.        
    
              (c)  The Committee shall perform all of the 
    Fiduciary Responsibilities with respect to the Plan            
    except those Fiduciary Responsibilities which are              
    allocated or delegated pursuant to paragraph (b) above         
    and those Fiduciary Responsibilities which are to be           
    performed by the Trustee pursuant to the Trust                 
    Agreement.

         11.5  Power to Interpret.  The Committee shall 
have the exclusive right to interpret the Plan and to 
determine any question arising under or in connection  
with the administration of the Plan.  Its decision or 
action in respect thereof shall be conclusive and binding 
upon all persons having an interest in the Trust Fund or 
under the Plan.

         11.6  Accounts.  The Trustee shall cause to be 
maintained accounts showing transactions under the Plan 
and the interests of Participants and any beneficiary or 
beneficiaries.  A separate account shall be maintained   
by the Trustee for each Participant and any beneficiary  
to which there shall be credited the Shares and other 
assets allocated to him, and to which there shall be 
charged the amount of any payments made with respect to 
his interest.  At least annually the Trustee shall  
furnish to each Participant and any beneficiary having   
an interest in the Trust Fund a summary statement of the 
transactions of the Trust Fund since the date of the last 
previous statement so furnished and of his interest in  
the Trust Fund.  Any such Participant or beneficiary who 
does not notify the Trustee as to any objection which he 
may have with respect to any such statement within 90

days after the date of distribution thereof shall be 
conclusively presumed to have approved the transactions 
reflected therein.

         11.7 Indemnification.  The Company will  
indemnify and save harmless each member of the Committee 
and any other person to whom Fiduciary Responsibilities 
are allocated or delegated under Section 11.4(b) against 
any claim, cost, expense (including attorney's fees) or 
liability (including any sum paid in settlement of a  
claim with the approval of the Company) arising out of  
any act or omission to act as a member of the Committee, 
or as a delegate, except in the case of willful 
misconduct.

SECTION 12.   Amendment, Suspension and Termination; 
              Merger, Consolidation and Transfer.


         12.1  Amendment.


               (a)  The provisions of the Plan may be 
    amended at any time and from time to time by the           
    Board of Directors (for the Company and for the other      
    Participating Companies), but no such amendment shall      
    have the effect of reinvesting in the Company or any       
    Participating Company any part of the Trust Fund or        




                                        
                                      
<PAGE>   44
    of diverting any part of the Trust Fund to any         
    purpose other than for the exclusive benefit of the    
    Participants or, subject to Section 12.1(b), of        
    reducing any interest of any Participant in the Trust  
    Fund which has accrued prior to any such amendment     
    or increasing the eligibility of officers with         
    respect to allocation of Company Contributions under   
    the Plan.  Without limiting the generality of the      
    foregoing, any such amendment relating to the manner   
    of determining the amount of the Company               
    Contributions may be made applicable to the            
    computation of such contribution for the entire Year   
    in which the amendment is adopted by the Board of      
    Directors, irrespective of the date on which such      
    amendment is adopted.                                  

              (b)  Notwithstanding anything to the   
    contrary herein contained, the Board of Directors may     
    make any and all changes or modifications                 
    (retroactively, if necessary) which in the opinion        
    of the Board of Directors are necessary or advisable      
    in order to comply with the provisions of the             
    Internal Revenue Code, ERISA, the Tax Reduction Act       
    or any other applicable law or regulation pertaining

    to employee stock ownership plans.
    
         12.2  Suspension and Termination.  The Company 
reserves the right, by action of the Board of Directors 
prior to the timely filing of the Company's Federal  
income tax return for any Year, to suspend the operation 
of the Plan by omitting all Company Contributions for  
such Year.  In the event the operation of the Plan is so 
suspended for any Year or Years all the provisions of the 
Plan and Trust Agreement, other than those relating to 
Company Contributions for such Year or Years, shall 
continue in effect.  The Company further reserves the 
right, by action of its Board of Directors, to terminate 
the Plan either completely or partially, or to  
discontinue completely Company Contributions thereto, at 
any time, but no such action may be made effective as of  
a prior Year.  In the event of any such termination, 
partial termination or complete discontinuance of Company 
Contributions, the Board of Directors may either continue 
the Trust Agreement in effect with respect to 
contributions theretofore made or terminate the Trust 
Agreement as well as the Plan.  If the Trust Agreement   
is terminated, the assets of the Trust Fund shall be 
distributed among the Participants (with the interest of




                                         
                                      
<PAGE>   46
any Participant who has died being distributed to his 
designated beneficiary or beneficiaries) in proportion   
to the respective interests in the Trust Fund of such 
Participants; provided, that any Participant or  
designated beneficiary having an interest in the Trust 
Fund may request the Trustee in writing to convert said 
interest entirely into cash prior to distribution thereof 
and the Trustee shall comply with such requests, on a 
uniform and non-discriminatory basis among such 
Participants and designated beneficiaries, to the extent 
practicable, as determined by the Trustee.  In the event 
of any such termination or partial termination of the 
Plan, or complete discontinuance of Company Contributions 
thereto, all Participants' interests in the Trust Fund 
shall be 100% nonforfeitable, except to the extent that 
Shares or other assets may be withdrawn from the Trust 
Fund as provided in Sections 3.6(b)(iii) or 7.4.

         12.3  Merger, Consolidation or Transfer.  In the 
event of any merger or consolidation with, or transfer   
in whole or in part of the assets and liabilities of the 
Trust Fund to, any other trust plan (the "New Plan") of 
deferred compensation maintained or to be established for 
the benefit of all or some of the Participants of this




                                        
                                      
<PAGE>   47
Plan, the assets and liabilities of the Trust Fund 
applicable to such Participants shall be transferred to 
the New Plan only if:
    
              (i)    Each such Participant would receive    
    a benefit immediately after the merger, consolidation   
    or transfer (if the New Plan had then terminated)       
    which is equal to or greater than the benefit such      
    Participant would have been entitled to receive         
    immediately before the merger, consolidation or         
    transfer (if this Plan had then terminated);            

              (ii)   Resolutions of the Board of Directors 
    (for the Company and for the Participating                   
    Companies), or of the board of directors of any new or       
    successor employer of the affected Participants, shall       
    authorize such transfer of assets; and, in the case of       
    the new or successor employer of the affected                
    Participants, its resolutions shall include an               
    assumption of liabilities with respect to such               
    Participants' inclusion in the New Plan; and                 

              (iii)  The New Plan and Trust, if any, are 
    qualified under Sections 401 and 501 of the Internal
    Revenue Code.

SECTION 13.   Miscellaneous.

         13.1 Benefits Payable from Trust Fund.  All 
persons with any interest in the Trust Fund shall look 
solely to the Trust Fund for any payments with respect   
to such interest.

         13.2  Designation of Beneficiary.  Each 
Participant may designate a beneficiary or beneficiaries 
and may change such designation from time to time by 
filing a written designation of beneficiaries with the 
Secretary of the Committee on a form to be prescribed by 
it, provided that no such designation shall be effective 
unless so filed prior to the death of such Participant.

         13.3  Elections.  Elections hereunder shall be 
made by a Participant in writing by the completion and 
delivery to the Secretary of the Committee of forms 
prescribed by the Committee for such purposes, within the 
time limits set forth hereunder with respect to each such 
election or, if no time limit is set forth, as may be 
established by the Committee.




                                        
                                      
<PAGE>   49
         13.4  No Right to Continued Employment.  Neither 
the establishment of the Plan nor the payment of any 
benefits thereunder nor any action of the Company, any 
Participating Company, the Board of Directors or the  
board of directors of any Participating Company, the 
Committee or the Trustee shall be held or construed to 
confer upon any person any legal right to be continued   
in the employ of the Company or any Participating  
Company, and the Company and each Participating Company 
expressly reserves the right to discharge any employee 
whenever the interest of any such company in its sole 
judgment may so require without liability to the Company, 
any Participating Company, the Board of Directors or the 
board of directors of any Participating Company, the 
Committee or the Trustee except as to any rights which  
may be conferred upon such employee under the Plan with 
respect to his interest in the Trust Fund.

         13.5  Inalienability of Benefits and Interests. 
No benefit payable under the Plan or interest in the  
Trust Fund shall be subject in any manner to  
anticipation, alienation, sale, transfer, assignment, 
pledge, encumbrance or charge, and any such attempted 
action shall be void and no such benefit or interest




                                        
                                      
<PAGE>   50
shall be in any manner liable for or subject to debts, 
contracts, liabilities, engagements or torts of any 
Participant or beneficiary.  If any Participant or 
beneficiary shall become bankrupt or shall attempt to 
anticipate, alienate, sell, transfer, assign, pledge, 
encumber or charge any benefit payable under the Plan or 
interest in the Trust Fund, then, to the extent permitted 
by law, the Committee in its discretion may hold or apply 
such benefit or interest or any part thereof to or for  
the benefit of such Participant, or his beneficiary, his 
spouse, children, blood relatives, or other dependents,  
or any of them, in such manner and in such proportions   
as the Committee may consider proper.  Notwithstanding  
the foregoing, any Participant may direct that benefits 
payable pursuant to Section 9 from the Trust Fund shall  
be paid to the trustee of a trust created by him for his 
own benefit or for the benefit of his immediate family.

         13.6  Payments Due Infants or Incompetents.  If 
any person to whom a benefit is payable hereunder is an 
infant, or if the Committee determines that any person to 
whom a benefit is payable is incapable by reason of 
physical or mental disability of taking care of his own 
affairs, the Committee shall have power to cause the




                                        
                                      
<PAGE>   51
payments becoming due to such person to be made to  
another for his benefit without responsibility of the 
Committee or the Trustee to see to the application of  
such payments.  Payments made pursuant to such power  
shall operate as a complete discharge of the obligation  
of the Company, any Participating Company, the Trust  
Fund, the Trustee and the Committee to make such  
payments.

         13.7  Payments for Exclusive Benefits of 
Participants.  Payments of benefits in respect of the 
interest of a Participant under the Plan to any person 
other than such Participant in accordance with the 
provisions of the Plan shall be deemed to be for the 
exclusive benefit of such Participant.

         13.8  Procedure for Denial of Claims.  Subject  
to such regulations as may be prescribed by the Secretary 
of Labor, the Committee shall provide written notice to 
any Participant or surviving beneficiary whose claim for 
benefits under the Plan has been denied, setting forth  
the specific reasons for such denial.  The Committee  
shall afford a reasonable opportunity to any such person 
whose claim for benefits has been denied for a full and 
fair review by the Committee of the decision denying the




                                        
                                      
<PAGE>   52
claim.

         13.9  Profit Sharing or Bonus Payments Outside  
of the Plan.  The adoption of the Plan shall not be 
construed as limiting the authority of the Board of 
Directors to pay bonuses to, and to establish from time  
to time, and to amend or discontinue, profit sharing, 
stock bonus or other supplemental compensation plans for, 
persons employed by the Company or by any branch thereof 
or by any affiliate of the Company who are not eligible to 
participate in the Plan and to pay bonuses or other 
supplemental compensation to Participants in addition to 
any amounts allocated to them hereunder if deemed 
advisable by the Board of Directors.

         13.10  Agent for Service of Process.  The 
Secretary of the Company shall be the Plan's designated 
agent for service of legal process.

         13.11  Texas Law to Govern.  This Plan shall be 
construed and enforced in accordance with the laws of the 
State of Texas and applicable Federal law.

     Pursuant to the provisions of Section 12.1 thereof, 
the Employee Stock Ownership Plan of American Petrofina, 
Incorporated is hereby amended in the following respects 
only:

     FIRST:  Section 1.15 is hereby amended by restatement 
in its entirety to read as follows:

          "1.15  `Matching Employee Contributions' shall 
     mean for any Year the aggregate of the Employee Contributions 
     for such Year which qualify to be matched                     
     by Company Contributions under Internal Revenue Code          
     Section 48(n)."                                               

     SECOND:  Sections 3.1, 3.2, 3.3, 3.4, 3.5 and 3.6 are 
hereby amended by restatement in their entirety to read as 
follows:

          "3.1   Company Contributions.  For each Year 
     commencing after December 31, 1978, the Company and    
     each Participating Company shall contribute, in such   
     proportions as such companies shall together agree, to 
     the Trust Fund cash or Class A Shares of an aggregate  
     value equal to the additional investment credit, if    
     any, claimed under Internal Revenue Code Section       
     46(a)(2)(A)(iii) with respect to the aggregate qualified 
     investment of the Company and all Participating   
     Companies, as determined under Internal Revenue Code   
     Sections 46(c) and 46(d) (the "Company Contribution"). 
     To the extent that a Company Contribution is in cash,  
     such cash shall be used by the Trustee within 30 days  
     of receipt to purchase Class A Shares.  Except as      
     provided in Section 3.5, no other contributions to the 
     Trust Fund shall be required or permitted."             

          "3.2  Time of Company Contributions.  Company 
     Contributions in cash and in Class A Shares shall be 
     transferred to the Trust Fund no later than 30 days  





<PAGE>   57
     after the due date (including extensions) for filing  
     the Company's Federal income tax return for the Year  
     for which the Company Contributions are made;         
     provided, that if any additional investment credit of 
     the Company or any Participating Company determined   
     under Internal Revenue Code Section 46(a)(2) exceeds  
     the limitations on allowable tax credit under Internal
     Revenue Code Section 46(a)(3), then                   

              (i) that portion of the Company Contribution 
     allocable to investment credit carrybacks of such 
     excess credit shall be transferred to the Trust   
     Fund within the time prescribed in Section 3.2    
     above for the Company Contribution for the unused 
     credit year, as defined in Internal Revenue Code  
     Section 46(b), and                                

              (ii) that portion of Company Contribution 
     allocable to investment credit carryovers of such
     excess credit shall be transferred to the Trust  
     Fund within the time prescribed in Section 3.2   
     above for the Year to which such portion is      
     carried over."                                    

         "3.3  Valuation of Share Contributions.  For 
     purposes of Section 3.1 above, Company Contributions in 
     Class A Shares shall be valued by taking the average    
     of closing sale prices of the Class A Shares, as        
     reported by the composite tape for securities listed    
     on the American Stock' Exchange, Inc., for the 20       
     consecutive trading days immediately preceding the      
     date on which the Company's Federal income tax return   
     is filed for the Year with respect to which such        
     Company Contributions are made."                          

         "3.4 Initial Plan Qualification.  Any provision 
     of this Plan to the contrary notwithstanding, if an  
     application for a determination that the Plan        
     satisfies the requirements of Internal Revenue Code  
     Section 409A is filed with the Internal Revenue      
     Service not later than 90 days following the date on 
     which the Company's 1979 tax credit under Section 38 
     of the Internal Revenue Code is claimed, and if such 
     determination is not issued, then, no later than one 
     year after the date on which the Internal Revenue    
     Service issues notice to the Company that the Plan   
     does not satisfy said requirements, all Company      
     Contributions made to the Trust Fund                 





<PAGE>   58
     with respect to Years Commencing after December 31, 
     1978, to the extent not previously distributed to   
     Participants or beneficiaries, shall be returned to 
     the Company and the Participating Companies by the  
     Trustee at the direction of the Committee.          

         "3.5 Employee Contributions.  For each Year 
     commencing after December 1, 1978, each Participant may 
     elect to make voluntary Employee Contributions in cash  
     to the Trust Fund in an amount not less than 2% nor     
     more than 10% of the Participant's Compensation for     
     the Year; provided, that such Participant must          
     designate in writing that his Employee Contributions    
     for that Year shall be available as Matching Employee   
     Contributions. Such Employee Contributions shall be     
     made by payroll deductions or such other means as the   
     Committee may prescribe.  Employee Contributions shall  
     be accumulated and held by the Company, without         
     interest, and shall be transferred to the Trust Fund    
     at the end of each quarter of the Year.  Employee       
     Contributions shall be used by the Trustee as soon as   
     reasonably practicable, but in no event later than 60   
     days after the due date (including extensions) for the  
     filing of the Company's Federal income tax return for   
     the Year for which said Employee Contributions were     
     made, to purchase Class A Shares."                       

         "3. 6 Credit Recapture or Redetermination.  If 
     any amount of the credit claimed by the Company or a    
     Participating Company for a prior Year under Internal   
     Revenue Code Section 38 is recaptured under Internal    
     Revenue Code Section 47, or if such credit is reduced   
     because of a redetermination of Federal income tax for  
     such prior Year which becomes final during the current  
     Year, and Company Contributions were made to the Trust  
     Fund for such prior Year, then the Company or           
     Participating Company (i) may reduce the amount of its  
     Company Contribution otherwise due the Plan for the     
     current Year, or for any succeeding Year, by an amount  
     equal to the portion of the amount so recaptured, or    
     the portion of the amount of such reduction in the      
     credit or increase in tax, which is attributable to     
     its Company Contribution to the Trust Fund, or (ii) to  
     the extent not taken in account under phase (i) above,  
     may deduct an amount equal to such portion subject to   
     the limitations of Internal Revenue Code Section 404."

in its entirety to read as follows:

    Shares directly attributable to Company Contributions 
    which may be made without regard to any Matching Employee 
    Contributions for the Year, as determined under
    Internal Revenue Code Sections 46(a)(2) and           
    48(n)(1)(A), shall be allocated (to the nearest 1/100 
    of a Share) as of the end of each such Year to the    
    account of each Participant who completed at least    
    1,000 Hours of Service while a Participant during such
    Year in an amount which bears substantially the same  
    proportion to the amount of all such Shares allocated 
    for such Year to all such Participants as the amount  
    of such Participant's Compensation for that Year (not 
    in excess of $100,000) bears to the Compensation paid 
    to all such Participants during that Year             
    (disregarding each Participant's Compensation in      
    excess of $100,000)."                                  
    
         "(b) All Class A Shares directly attributable to 
    Company Contributions which may be made only to match 
    Matching Employee Contributions for the Year, as      
    determined under Internal Revenue Code Sections       
    46(a)(2) and 48(n)(1)(B), shall be allocated as of the
    end of such Year to the account of each Participant   
    eligible to share in the allocation under Section     
    4.1(a) above, in an amount equal to such Participant's
    share of the Matching Employee Contributions to the   
    Trust Fund for such Year."                             
    
         "(c) All Class A Shares purchased with Employee 
    Contributions shall be allocated, as soon as           
    reasonably Practicable after they are purchased by the 
    Trustee, to the accounts of the Participants who made  
    such Employee Contributions."                          
    
    FOURTH:   Effective with respect to allocations made 
for Years commencing after December 31, 1979, Paragraph

Company Contributions which may be made without regard to 
any Matching Employee Contributions for the Year, as 
determined under Internal Revenue Code Sections 46(a)(2) and 
48(n)(1)(A), shall be allocated (to the nearest 1/100 of a 
Share) as of the end of each such Year to the account of 
each Participant who either was in the employ of the 
Company or a Participating Company on the last day of such 
Year, or whose employment with the Company or a Participating 
Company terminated during such Year by reason of 
death or by reason of retirement under the normal or early 
retirement or disability benefit provisions of the Pension 
Plan for Non-Represented Employees of American Petrofina, 
Incorporated and Certain Subsidiaries, in an amount which 
bears substantially the same proportion to the amount of 
all such Shares allocated for such Year to all such 
Participants as the amount of such Participant's Compensation 
for that Year (not in excess of $100,000) bears to the 
Compensation paid to all such Participants during that 
Year (disregarding each Participant's Compensation in 
excess of $100,000)."

    FIFTH:  The reference in Section 7.3 to "Internal 
Revenue Code Section 46(a)(2)(B)" is hereby amended to

46(a)(2)(A)."

Year, a Participant may irrevocably elect in writing to 
withdraw from the Trust Fund all or any whole number of 
the Shares which, as of December 31 of such Year, have 
been allocated to and have remained in such Participant's 
account for a period of at least 84 months after the month 
in which such Shares were allocated to his account; 
provided, however, that the Shares referred to in this 
Section 9.1(a) shall be eligible for the election to 
withdraw only in the Year in which such Shares first 
satisfy said 84-month requirement."

    EIGHTH:   Section 9.7  is hereby amended by 
restatement in its entirety to read as follows:

         "9.7   Disability and Hardship Distributions.  In 
    case of disability, a Participant may apply in writing 
    to the Committee at any time for the immediate         
    distribution of all or any whole number of Shares not  
    otherwise distributable from the Trust Fund.  In case  
    of hardship, any beneficiary designated by a deceased  
    Participant may so apply for the immediate             
    distribution of all or any whole number of Shares not  
    otherwise distributable from the Trust Fund.           
    Distributions pursuant to this Section 9.7 shall be    
    made only to the extent that the Committee, in its     
    absolute discretion, determines such to be necessary   
    to alleviate the burdens of such disability or         
    hardship.  In making such determinations the Committee 
    shall use its best efforts to follow uniform and       
    nondiscriminatory practices, and its determinations    
    shall be final and binding.  For the purposes of this  
    Section 9.7, (i) disability shall mean incapacity      
    (whether temporary or permanent) from gainful employment 
    and (ii) hardship shall mean a need for financial 
    assistance in meeting obligations incurred or to be    
    incurred by a designated beneficiary of a deceased     
    Participant for his health or welfare or for the       
    health or welfare of members of his immediate family." 

    NINTH:  The reference in the last sentence of Section
12.2 to "Sections 3.6(b)(iii) or 7.4" is hereby amended to 
make reference to "Section 7.4".

     IN WITNESS WHEREOF, this Amendment has been executed 
by the Company on behalf of itself and all Participating 
Companies on this 12th day of September, 1980, the FOURTH 
and SEVENTH provisions hereof to be effective as of

FINA CAPITAL ACCUMULATION PLAN - 3
<PAGE>   8

who is reemployed following his Termination of Employment shall 
recommence participation as of the first day of the month following

    Section 2.4. Special Rules for Change in Status.

     (a) Participation.

         Change to Eligible Employee Status. A person who changes status  
         from an Ineligible Person (as defined at Section  17.15) to Eligible
         Employee (as defined in Section 17.15)  shall become a Participant in
         the Plan on the later of:

             (i)  the first day of the month following the date on which he
                  first completes an Hour of Service as an Eligible  Employee,
                  or

             (ii) the Entry Date coincident with or next following the date on
                  which he becomes a Participant in accordance with the 
                  requirements of
                  Section 2.1.

         Allocation of the Employer Contribution and Forfeitures, if any,
         for such a Participant for the Plan Year during which such change in
         status occurs shall be based solely on his Compensation as determined
         in accordance with Section 2.2  and his Employee After-Tax and/or
         Employee Pre-Tax  Contributions.

     (b) Change to Ineligible Person Status. A Participant who  ceases to
         be an Eligible Employee but continues to be an Employee (including a
         Participant who becomes a member of a  collective bargaining unit the
         recognized representative of which has not agreed to participation in
         the Plan by  members) shall continue to participate in the Plan for
         all  purposes except that he shall not accrue any further benefit nor
         shall he be entitled to make further Employee  After-Tax or Employee
         Pre-Tax Contributions (if any are  otherwise permitted). However, a
         Participant who ceases to  be an Eligible Employee shall be entitled
         to share in the  Employer Contributions and Forfeitures (if otherwise
         herein  applicable) for the Plan Year during which such change in 
         status occurs based solely on his Compensation, and  Employee
         After-Tax and/or Employee Pre-Tax Contribution  (made prior to such
         change in status) for such Plan Year as  an Eligible Employee.

                             ARTICLE III

               PARTICIPANT AND EMPLOYER CONTRIBUTIONS

    Section 3.1. Participant Elections. Except as herein limited, 
each Eligible Employee who has satisfied the requirements for 
participation may file a written election, on forms to be provided by 
the Committee, directing his Employer to:

     (a)  Pre-Tax Contributions. Withhold a uniform amount 
from his Basic Compensation and make an Employee Pre-Tax 
Contribution of a corresponding amount to the Plan. Such  
salary deferral election may only direct the withholding 
from the Participant's Basic Compensation within the range  
set forth at Section 1.3. Such salary deferral elections  
must be elected in even one percent (1%) increments. All  
such Employee Pre-Tax Contributions shall be credited to  
the Participant's Employee Pre-Tax Account.

              (i)  Calendar Year Individual Pre-Tax ($7,000) Limitation.        
                   Notwithstanding any other provision of the Plan, for each
                   calendar year (regardless of the Plan Year) no  Participant
                   shall contribute an amount through an  Employee Pre-Tax
                   Contribution which exceeds $7,000  (adjusted from time to
                   time for any cost-of-living  increase adjustment provided
                   pursuant to Code Section  4O2(g)(5)).

                   If the Plan would otherwise receive an amount of a 
                   Participant's Pre-Tax Contribution in excess of the 
                   foregoing limit, such amount shall, depending on the 
                   Participant's prior election, either  (A) be deducted        
                   each pay period and contributed as Employee After-Tax 
                   Contributions described in Subsection (b) in addition  to
                   the Participant's other After-Tax Contributions or  (B) if
                   no such election has been made, be deemed an  "Excess
                   Deferral" and be dealt with as provided at  Subparagraph
                   (ii) immediately below.

              (ii) No Distribution of Excess Deferrals. If any portion of       
                   a Participant's Pre-Tax Contributions under this Plan  is
                   designated an Excess Deferral, such Excess Deferral  shall
                   not be distributed until the time it would have  been
                   distributed if such designation had not been  made.

     (b)  After-Tax Contribution. Make an Employee After-Tax 
Contribution to the Plan for each pay period in an amount, 
within the range set forth at Section 1.4, of such Basic 
Compensation. Such employee After-Tax Contribution election 
must be elected in even one percent (1%) increments.




FINA CAPITAL ACCUMULATION PLAN - 5
<PAGE>   10
    (c)  Time for Making or Changing Pre-Tax and/or After-Tax  Elections.
         The applicable percentage of payroll deductions  semiannually
         (as of any date set forth in Section 1.5, or  such other semiannual
         dates as the Committee may from time  to time establish, upon
         reasonable notification to  Participants) by providing written notice
         to the Committee  on a form, in a manner and at such time prior to the 
         payroll period to which it applies as prescribed by the  Committee.

    (d)  Suspension of Contribution Elections. Notwithstanding the limitations
         at Subsection 3.1(c) above, at such time(s) and for such minimum 
         period as provided in Section 1.6,  suspend his Employee Pre-Tax 
         and/or After-Tax  Contributions, by providing written notice to the 
         Committee  (on a form and in a manner prescribed by the Committee) at
         such time prior to the first payroll period to which such suspension 
         applies as the Committee may from time to time administratively 
         establish, provided reasonable notice of such deadline is provided to
         Participants.

         Participant's Employee Pre-Tax Contributions or Employee  After-Tax
         Contributions shall resume automatically at the  prior rate(s) or if
         such Participant chooses (within the   permissible range of such
         contributions) by filing an  appropriate written election at the time
         and in the manner  set forth above for such Participant elections, at
         any  different rate selected by the Participant. No retroactive 
         contributions may be made by or on behalf of a Participant.

    (e)  Omission of Eligible Employee.  Notwithstanding the  preceding
         provisions of this Section 3.1, if, in any Plan  Year, any Employee
         who should be included as a Participant in the Plan is
         erroneously omitted through an  administrative error, such omission
         shall be corrected as  soon as administratively feasible.  If the
         omission is  discovered after a contribution by the Employer for the 
         year has been made, then the Employer shall make a  subsequent
         contribution with respect to the omitted  Employee in the amount which
         the Employer alone would have  contributed with respect to him had he
         not been omitted and  assuming solely for these purposes that the
         omitted  Employee had made the maximum permissible Employee Pre-Tax 
         Contribution and Employee After-Tax Contribution.  Such  Employer
         contribution shall be made regardless of whether  or not it is
         deductible in whole or in part by the Employer  in any taxable year
         under applicable provisions of the  Code.

    (f)  Inclusion of Ineligible Employee.  If any person is  erroneously
         included and such incorrect inclusion is  discovered after an Employee
         After-Tax Contribution or Employee Pre-Tax Contribution (or both)
         or after an  Employer Matching Contribution for the year has been
         made,  the Employee After-Tax and/or Employee Pre-Tax  Contributions
         shall be treated as made under a mistake of  fact and the Employee
         After-Tax or Employee Pre-Tax  Account(s) resulting therefrom shall be
         returned to the



FINA CAPITAL ACCUMULATION PLAN - 6
<PAGE>   11
         individual, as soon as administratively feasible, but such  returned
         monies shall not exceed the actual amount  contributed as Employee
         After-Tax and Employee Pre-Tax  Contributions.  Further, the Employer
         shall not be entitled  to recover the Employer Matching Contribution
         made with respect to the Ineligible Person regardless of whether
         or  not a deduction is allowable with respect to such  contribution. 
         In such case, the amount of Employer  Matching Contribution with
         respect to the Ineligible Person  shall constitute a forfeiture for
         the Plan Year in which  the discovery is made.

      Section 3.2.  Employer Matching Contributions Subject to the  Limitations
of Article IV.
   
    (a)  General Rule.  An Employer shall, out of its Net Profits,      
         make a Matching Contribution to the Plan for each  Participant in its
         employ in an amount which, when added to  any forfeiture amount being
         credited to such Participant  for that pay period, will equal the
         amount determined at  Section 1.7(a).

    (b)  Increased Match.  Effective July 1,  1991,  the Employer       
         Matching Contribution shall be the amount determined at  Section
         1.7(b).

     Section 3.3 Payment to Trustee.  The Employee After-Tax and 
Employee Pre-Tax Contributions for a pay period ending within a 
particular month shall be sent to the Trustee in cash no later than 
30 days after the end of such month.  The Matching Contribution may 
be made in cash or in the form of Company Stock, or in any 
combination thereof, and shall be sent to the Trustee no later than 
30 days after the end of such month.  The value of any Company Stock 
contributed as a Matching Contribution shall be the closing price of 
such stock on the open market as of the date of contribution if such 
stock was traded on the open market on such date.  If such stock was 
not traded on the open market as of the date of the contribution, 
then the value of the Company Stock shall be the closing price of 
such stock on the open market as of the date next preceding the date 
of the contribution that such stock was traded on the open market.  
If any Employer is prevented from making a contribution which it 
would otherwise have made by reason of having no Net Profits or 
because Net Profits are less than the contribution which it would 
otherwise have made, then so much of the contribution which such 
Employer was prevented from making shall be made for the benefit of 
the Participants in the employ of such Employer by the other 
Employers to the extent of their Net Profits in such proportions as 
such other Employers may determine.

     Section 3.4.  Limitations.

     (a)  Limitation on Employee Pre-Tax Contribution.

          (1)  Notwithstanding anything herein to the contrary, if 
               the Actual Deferral Percentage of Highly Compensated 
               Participants exceeds the greater of:

               (i)  1.25 times the Actual Deferral Percentage of all 
                    Non-Highly Compensated Participants for such Plan 
                    Year, or

               (ii) 2 times the Actual Deferral Percentage of 
                    Non-Highly Compensated Participants, provided 
                    that the Actual Deferral Percentage for 
                    Participants who are Highly Compensated Employees 
                    does not exceed the Actual Deferral Percentage of 
                    Non-Highly Compensated Participants by more than 
                    two (2) percentage points,

               or if total Employer Contributions for one or more 
               Participants exceed the applicable limitations of 
               Section 4.1, then the Committee shall take the actions 
               described in paragraphs (2) through (4) below.

               In determining a Highly Compensated Participant or 
               Non-Highly Compensated Participant for purposes of 
               this Section, only Employees who have satisfied the 
               eligibility requirements of Section 2.1, whether or 
               not they made a before tax Salary Deferral 
               Contribution, shall be considered.

          (2)  First, reduce the Employee Pre-Tax Contributions 
               allocable to each affected Participant so as to 
               satisfy the applicable Code Section 415 limitations of 
               Section 4.1.

          (3)  Next, in accordance with Reg.  Section 1.401(k)-1(f)(2), 
               reduce the Employee Pre-Tax Contributions of those 
               Highly Compensated Participants whose deferral 
               percentages are the highest (working in descending 
               order) which, once reduced, will be sufficient to 
               comply with paragraph (a)(1) above.

               Example of Reduction Method:  If Employees A, B and C 
               (all Highly Compensated Participants) had the 
               following compensation and deferral percentages:





FINA CAPITAL ACCUMULATION PLAN - 8
<PAGE>   13
               Employee             Compensation           Deferral
               A                    $100,000                 7.0%
               B                    $200,000                 3.5%
               C                    $200,000                 3.0%
               ADP                                           4.5%

               If necessary to achieve an ADP of 3.3, it would only be 
               necessary to reduce Employee A to 3.5 (3.5 + 3.5 + 3.0 = 3.3).
               If it were necessary to reduce the ADP below 3.3,  then it would
               it become necessary to reduce both Employee A and B.

               Nothing herein shall be deemed to prohibit the Committee  from
               soliciting additional Employee Pre-Tax Contributions  from 
               Non-Highly Compensated Participants.

          (4)  If contributions exceed the Actual Deferral Percentage limits 
               provided for in Subsection 3.4(a)(1) (called "Excess 
               Contributions" in the Code) at the end of the Plan Year, such 
               Excess Contribution (and any income allocable to such  
               contribution) shall be returned to the Highly Compensated  
               Employees whose Pre-Tax Contributions were reduced at paragraph
               (3) above, if administratively reasonable, within  2-1/2 months
               after the close of such Plan Year, but in no  event later than 
               the end of the next Plan Year.

               Income allocable to such Excess Contributions is equal to the 
               sum of the allocable gain or loss for the Plan Year and the
               allocable gain or loss for the period from the end of the
               Plan Year until the date of distribution.  Income  allocable to
               Excess Contributions for the Plan Year is  determined by 
               multiplying the total income for the Plan  Year attributable to
               Pre-Tax Contributions by a fraction  the numerator of which is 
               the Excess Contributions on  behalf of the Highly Compensated 
               Employee for the Plan Year  and the denominator of which is 
               such Employee's Pre-Tax Account balance at the end of the Plan 
               Year reduced by any  gain allocable to such Account for the Plan
               Year and increased by any loss allocated to such Account for the
               Plan Year.  Income allocable to the period between the end of 
               the Plan Year and the date of distribution of the Excess 
               Contribution is 10% of the income for the Plan Year  multiplied
               by the number of months that have elapsed since the end of the 
               Plan Year.  For this purpose a distribution  will be treated as
               made on the last day of the preceding month if it is made on or
               before the 15th day of the month  and at the end of the month
               if it is made after the 15th  day of that month.

          (5)  If the Employer has a plan or plans that must be treated 
               (with this Plan) as one plan for purposes of Sections 401(a)(4)
               and  410(b) of the Code, all elective (401(k)) contributions 
               made under  this Plan and such plans shall be treated as made 
               under a single plan.
               
          (6)  If for any Plan Year any Highly Compensated Employee is 
               eligible to participate in more than one cash or deferred 
               (401K)) arrangement of an Employer, the Actual Deferral 
               Percentage shall be calculated by treating all cash or deferred
               arrangements in which such Highly Compensated Employee is 
               eligible to participate as one arrangement.

     (b)  Definitions.  For purposes of this Article III, the following 
terms shall have the following designated meanings:

               (i)  "Actual Deferral Percentage" for each Plan Year means 
                    the average of the fractions of each Participant, where 
                    the numerator of the fraction is the amount allocated to 
                    the Participant Employee's Pre-Tax Contribution Account 
                    and the denominator is his or her Compensation for such 
                    Year.  For purposes of determining the ratio of Employee 
                    Pre-Tax Contributions to Compensation of a Highly 
                    Compensated Participant who is a five percent (5%) owner 
                    or one of the ten (10) Employees paid the highest 
                    compensation during the year, the Employee Pre-Tax 
                    Contributions and Compensation of such Highly Compensated 
                    Employee shall include the Employee Pre-Tax Contributions 
                    and Compensation of Family Members of such Highly 
                    Compensated Employee, and such Family Members shall be 
                    disregarded in determining the "actual deferral percentage" 
                    for Participants who are not Highly Compensated Employees.
                    Employee Pre-Tax Contributions may be taken into account 
                    for a Plan Year only if they are actually allocated to the
                    Participant's Account as of a day within that Plan Year.

               (ii) "Highly Compensated Participant" means an Employee who has
                    satisfied the eligibility requirements of Section 2.1 
                    whether or not he or she has made an Employee Pre-Tax 
                    Contribution election and who is further defined as a 
                    Highly Compensated Employee in Section 17.26 of this Plan.
                    Application of this test shall be made with reference to 
                    the rules at Code Section 414(q) and any applicable 
                    regulations thereto.

               (iii)"Non-Highly Compensated Participant" means an Employee 
                    who has satisfied the eligibility requirements of Section 
                    2.1 whether or not he or she has made an Employee Pre-Tax




FINA CAPITAL ACCUMULATION PLAN - 10
<PAGE>   15
                    Contribution election and who is further defined as a 
                    Non-Highly Compensated Employee in Section 17.27 of this 
                    Plan.

     (C)  Limitation on Matching Contributions and Employee After-Tax 
          Contribution.

          (1)  Notwithstanding anything herein to the contrary, if the 
               Average Contribution Percentage of Highly Compensated 
               Participants exceeds the greater of:

               (i)  1.25 times the Average Contribution Percentage of all 
                    Non-Highly Compensated Participants for such Plan Year, or

               (ii) 2 times the Average Contribution Percentage of Non-Highly 
                    Compensated Participants, provided that the Average 
                    Contribution Percentage for Participants who are Highly 
                    Compensated Employees does not exceed the Average 
                    Contribution Percentage of Non-Highly Compensated 
                    Participants by more than two (2) percentage points, 

               or if total Employer Contributions for one or more Participants 
               exceed the applicable limitations of Section 4.1, then the 
               Committee shall take the actions described in paragraphs (2) 
               through (4) below.

               In determining who is a Highly Compensated Participant or 
               Non-Highly Compensated Participant for purposes of this Section, 
               only such Employees who have satisfied the eligibility 
               requirements of Section 2.1, Whether or not they made a Pre-Tax
               Salary Deferral Contribution, shall be considered.

          (2)  First, reduce the Employee After-Tax Contributions and Matching
               Contributions allocable to each affected Participant so as to 
               satisfy the applicable Code Section 415 limitations of Section 
               4.1.

          (3)  Next, in accordance with Reg.  Section 1.401(m)-1(e)(2), reduce
               the Employee After-Tax Contributions and Matching Contributions
               of those Highly Compensated Participants whose contribution 
               percentages are the highest (working in descending order) which,
               once reduced, will be sufficient to comply with paragraph (c)(1)
               above.

               This same reduction process shall be used to the extent 
               necessary to reduce the Average Contribution Percentage of 
               Highly Compensated Employees to the extent necessary to comply 
               with the




FINA CAPITAL ACCUMULATION PLAN - 11
<PAGE>   16
           requirements of Section 1.401(m)-2 of the Income Tax Regulations 
           precluding multiple use of the alternative [two percent (2%)] 
           limitation of Section 3.4(a)(1)(ii) and (c)(1)(ii).

      (4)  If contributions exceed the Average Contribution Percentage 
           limits provided for in Section 3.4(c)(1) (called "Excess Aggregate 
           Contributions" in the Code) at the end of the Plan Year, the amount 
           of the Excess Aggregate Contribution for such Plan Year (and any 
           income allocable to such contribution) shall be dealt with as 
           follows:

           (i)  First, Employee After-Tax Contributions that were not matched 
                by Matching Contributions shall be treated as Excess Aggregate
                Contributions, to the extent of such Excess Aggregate 
                Contributions and distributed to the Highly Compensated 
                Employee;

           (ii) Next, any remaining Excess Aggregate Contributions shall be 
                allocated pro rata to remaining Employee After-Tax 
                Contributions and Matching Contributions.  Excess Aggregate 
                Contributions so allocated to Employee After-Tax Contributions
                shall be distributed to the Highly Compensated Employees on 
                whose behalf they were contributed not later than two and 
                one-half (2-1/2) months after the close of the plan year for 
                which they were contributed.  Matching Contributions made with
                respect to such returned Employee After-Tax Contributions 
                shall be forfeited if forfeiture is permissible under Section 
                411 of the Code or, if forfeiture is not permitted by Section 
                411, distributed (with any income allocable thereto) at the 
                same time the Employee After-Tax Contributions are distributed.

                Income allocable to such Excess Aggregate Contributions is 
                equal to the sum of the allocable gain or loss for the Plan 
                Year and the allocable gain or loss for the period from the end
                of the Plan Year until the date of distribution.  Income 
                allocable to Excess Aggregate Contributions for the Plan Year 
                is determined by multiplying the total income for the Plan Year
                attributable to Employee After-Tax Contributions and Matching 
                Contributions by a fraction the numerator of which is the 
                Excess Aggregate Contributions on behalf of the Highly 
                Compensated Employee for the Plan Year and the denominator of 
                which is such Employee's Post-83 Match and Employee After-Tax 
                Account balances at the end of the Plan Year reduced by any 
                gain allocable to such Account for the Plan Year and increased
                by any loss allocated to such Accounts for the Plan Year.  
                Income allocable to the period




FINA CAPITAL ACCUMULATION PLAN - 12
<PAGE>   17
               between the end of the Plan Year and the date of distribution of 
               the excess contribution is 10% of the income for the Plan Year 
               multiplied by the number of months that have elapsed since the 
               end of the Plan Year.  For this purpose a distribution will be 
               treated as made on the last day of the preceding month if it is
               made on or before the 15th day of the month and at the end of 
               the month if it is made after the 15th day of that month.

     (5)  If an Employer has a plan or plans that must be treated (with this 
          Plan) as one plan for purposes of Sections 401(a)(4) and 410(b) 
          of the Code, all Employee After-Tax and Employee Matching 
          Contributions made under this Plan and such plans shall be treated as 
          made under a single plan.

     (6)  If for any Plan Year any Highly Compensated Employee is eligible to 
          participate in more than one arrangement of an Employer subject to 
          Section 401(m) of the Code, the Average Contribution Percentage shall
          be calculated by treating all such arrangements in which such Highly
          Compensated Employee is eligible to participate as one arrangement.

     (7)  For purposes of this Subsection  3.4(c):

          (i)  "Average Contribution Percentage" means for each Plan Year the 
               average of the fractions of each Participant, where the 
               numerator of the fraction is the amount allocated to the 
               Participant's After-Tax Account and Post-83 Match Account and 
               the denominator is his or her Compensation for such Year. For 
               purposes of determining the ratio of Employee After-Tax 
               Contributions and Matching Contributions to Compensation of a 
               Highly Compensated Employee who is a five percent (5%) owner or
               one of the ten (10) Employees paid the highest compensation 
               during that year, the Employee After-Tax Contributions, 
               Matching Contributions and Compensation of such Highly 
               Compensated Employee shall include the Employee After-Tax 
               Contributions, Matching Contributions and Compensation of 
               Family Members of such Highly Compensated Employee, and such 
               Family Members shall be disregarded in determining the Average 
               Contribution Percentage for Participants who are not Highly 
               Compensated Employees.

               Employee After-Tax Contributions and Matching Contributions may
               be taken into account for a Plan Year only if they are actually
               allocated to the Participant's Account as of a day within that 
               Plan Year.

any date during the Limitation Year under this Plan or  any other Defined
Contribution Plan maintained by any Employer:

             (i)  forfeitures and Employer contributions (which includes 
Participant Pre-Tax Contributions, which are for these purposes  employer
contributions); plus

             (ii) Employee After-Tax Contributions, if any (other than rollover 
contributions, if any); plus

             (iii)amounts allocated after March 31, 1984, to any individual 
medical account as defined in Code Section 415(i)(1) which is  part of any
qualified defined benefit plan maintained by the  Company, and

             (iv) amounts derived from contributions paid or accrued after

to post-retirement medical benefits allocated  to the separate account of any
Key Employee, under a welfare  benefit fund as defined in Code Section 419(e)
by any Employer.

                  However, amounts described in (iii) and (iv) above do not 
apply  in determining the percentage limit of Section 4.1(a)(ii).

     Section 4.2. Multiple Plan Reduction.
                            
     (a)  General Rule. If any Participant under this Plan is a Participant 
in one or more Defined Benefit Plans and one or more Defined  Contribution
Plans maintained by any Employer, the sum of his Defined  Benefit Plan Fraction
and the Defined Contribution plan Fraction as  defined by Sections 415(e)(2)
and (3) of the Code) for any such  Limitation Year may not exceed 1.0.

     (b)  The Defined Benefit Plan Fraction for any Limitation Year is a 
fraction in which the: (i)  numerator is the projected Annual Benefit  {as
defined at Subsection 4.2(g)} of the Participant under the Plan  (determined as
of the close of the Plan Year), and (ii) the  denominator is the lesser of: (A) 
product of 1.25 multiplied by the  maximum dollar limitation in effect under
Section 415(b)(1)(A) of the  Code for such Limitation Year, or (B) the product
of 1.4 multiplied  by the amount which may be taken into account under Section 
415(b)(1)(B) of the Code for such Limitation Year.

fraction in which the:  (i) numerator is the sum of the "annual  additions" to
the Participant's Account as of the close of the Plan  Year and the (ii)
denominator is the sum of the lesser of the  following amounts determined for
such year and each prior year of  service with any Employer:  (A) the product
of 1.25 multiplied by the  dollar limitation in effect under Section
415(c)(1)(A) of the Code  for such Limitation Year (determined without regard
to Section  415(c)(6) of the Code), or (B) the product of 1.4 multiplied by the 
amount which may be taken into account under Section 415(c)(1)(B) or  Section
415(c)(7), if applicable, of the Code for such Limitation  Year (For Limitation
Years beginning prior to January 1, 1987, annual  additions shall not be
recomputed to treat all employee contributions  as annual additions).

     (d)  For purposes of the preceding Subsection (c), the term 
"Participant's Account" shall mean the account(s) established and  maintained
for each Participant with respect to his total interest in  the Defined
Contribution Plan maintained by the Employer resulting  from the Employer's

     (e)  Effect of Top Heavy Plan Status on Multiple Plan Reduction Rule.  
Notwithstanding any other provision of this Plan, for any Top  Heavy Plan Year,
unless the Secondary Minimum Annual Allocation is  provided pursuant to
Subsection 13.2, and the secondary minimum  annual allocation or benefit
(whichever is applicable under Code  Section 416(h)) is provided under all
plans of the Required  Aggregation Group (as defined at Subsection 13.1(f)(i)
(or the 7-1/2  percent rule of Subsection 13.2, if applicable, is complied
with),  then in computing the denominators

<PAGE>   20
of the Defined Benefit and Defined Contribution Plan Fractions, a 
factor of 1.0 shall be substituted for 1.25 in Subsections 4.2(b) 
and (c). For any Super Top Heavy Plan Year 1.0 shall be substituted 
for 1.25 in any event.

     (f)  Excessive Benefit - Adjustment.  If the sum of the Defined 
Benefit Plan Fraction and the Defined Contribution Plan Fraction 
shall exceed 1.0 in any Limitation Year for any Participant in this 
Plan, the Committee shall reduce the Annual Additions to this Plan to 
the extent necessary to assure that the sum of both fractions shall 
not exceed 1.0 in any Limitation Year for such Participant, but only 
if the pension plan or plans do not provide for a reduction in 
benefit accruals to satisfy this limitation.

     (g)  Annual Benefit as used in this Article shall mean the 
pension benefit payable from the Pension Plan adjusted in accordance 
with Section 1.415-3(b)(1) of the Income Tax Regulations.

    Section 4.3. Definitions Relating to Annual Addition Limitations. 
For purposes of the Plan, the following definitions shall apply:

      (a)    "Retirement Plan" means (i) any pension, profit sharing, 
or stock bonus plan described in Section 401(a) of the Code, which 
includes a trust exempt from tax under Section 501(a) of the Code, 
(ii) any annuity plan or annuity contract described in Sections 
403(a) or 403(b) of the Code, (iii) any qualified bond purchase plan 
described in Section 405(a) of the Code, and (iv) unless exempt 
pursuant to Code Section 415(c)(2), any individual retirement 
account, individual retirement annuity or retirement bond described 
in Sections 408(a), 408(b) or 409 of the Code and any simplified 
employee pensions described in Section 408(k) of the Code.

      (b)    "Defined Contribution Plan" means a Retirement Plan 
(whether or not terminated) which provides for an individual account 
for each participant and for benefits based solely on the amount 
contributed to the participant's account, and any income, expenses, 
gains and losses, and any forfeiture of accounts of other 
participants which may be allocated to such participant's account.

      (c)    "Defined Benefit Plan" means any Retirement Plan 
(whether or not terminated) which is not a Defined Contribution Plan; 
provided, however, that if a Defined Benefit Plan provides for 
voluntary employee contributions, such voluntary employee 
contributions shall be considered as a separate Defined Contribution 
Plan for purposes of applying the limitations of Section 415 of the 
Code and the provisions of this Article.

      (d)      "Limitation Year" means the twelve consecutive month period 
ending on the last day of the Plan Year.




FINA CAPITAL ACCUMULATION PLAN - 16

or made available by the Company during a Limitation Year for 
services and includable in the Participant's gross income, including 
bonuses, overtime pay, vacation pay and disability pay, but excluding 
deferred compensation, stock options and other distributions which 
are excluded from gross income or receive special tax benefits.

      Section 4.4. Reduction of Annual Additions. If it is determined 
that the Annual Additions to a Participant's accounts for any 
Limitation Year would exceed the limitations of this Article, such 
Annual Additions shall be reduced to bring them within such 
limitations in the following manner:

      (a)    Employee After-Tax Contributions which are included in 
such Annual Additions shall be returned to the Participant to the 
extent permitted by Article III.

      (b)    If further reductions are necessary, then such 
Participant's allocable share of the Employer's contribution and/or 
forfeitures which have been applied in reduction of an Employer's 
obligations for the Plan Year ending within the Limitation Year shall 
be reduced.  The amount of such reduction shall be credited to an 
Unallocated Employer Contribution Account. Such Account shall not be 
subject to adjustment pursuant to Article V and shall be deemed an 
Employer contribution for the succeeding Plan Year.

Notwithstanding the foregoing, if a Participant in this Plan is also 
a participant in another qualified plan maintained by an Employer, 
the Committee may agree with the named fiduciaries of such other 
plans that adjustments to the Participant's accounts and/or benefits 
under such other plans shall be made in addition to or in lieu of the 
adjustments otherwise required by this Section in order to comply 
with the limitations of this Article and Section 415 of the Code.

                      AND DIRECTED INVESTMENTS

      Section 5.1. Plan Accounting Records.  The Committee shall, in 
conjunction with the Plan's recordkeeper, establish and maintain a 
set of accounting records for the Plan for the purpose of accounting

amounts attributable to




FINA CAPITAL ACCUMULATION PLAN - 17
<PAGE>   22
contributions made by such Participant to the First Thrift Plan, 
shall be allocated to such Participant's Employee After-Tax Account 
under this Plan.

      All Company Stock and other amounts attributable to 
contributions made by an Employer to the First Thrift Plan for a 
Participant shall be credited to such Participant's Pre-84 Match 
Account under this Plan.  All amounts attributable to Matching 
Contributions made by an Employer for a Participant pursuant to 
Section 3.2, and all forfeitures applied pursuant to Subsection 
6.3(c)(iv) to reduce the Matching Contributions which would otherwise 
have been made by an Employer for such Participant, shall be credited 
to such Participant's Post-83 Match Account under this Plan.

      All accounts maintained for a Participant shall sometimes be 
collectively referred to as "Account" or "Accounts".  All of the same 
type of Accounts maintained for a Participant shall sometimes be 
collectively referred to in the singular.  In addition, the Plan's 
accounting records shall otherwise be organized and contain such 
information as is necessary and desirable for the preparation of 
financial and other reports and information as required under the 
Plan or by law.

      The fair market value of trust assets shall be determined at 
least once in each Plan Year in accordance with a method consistently 
followed and uniformly applied, and the Accounts of all Participants 
shall be adjusted in accordance with the valuation.

    Section 5.2. Trust and Directed Investment Accounts.
                                                
      (a)    General Rules With Regard to Direction of Investments.  
The Committee shall notify all Participants that they may direct or 
redirect investment of their Accounts as herein set forth by filing a 
written direction with the Committee.  The Committee, in its sole and 
absolute discretion, shall establish and communicate to the 
Participants uniform and nondiscriminatory rules and policies in 
connection therewith which, by way of illustration only and not by 
way of limitation, may:

                (i) require that each Participant who directs the 
investment of his Accounts must control the investment of such entire 
Accounts;

              (ii)  limit the periods during which amounts may be 
transferred and their frequency of transfer to the first month of 
each quarter of the Plan Year, or to semiannual dates etc.

              (iii) limit the right of direction to investment in a 
qualified category of assets.

             Notwithstanding anything herein to the contrary, a 
Participant may direct the investment of his Accounts only in 
investments which are permitted under the provisions of the Plan and 
Trust which would




FINA CAPITAL ACCUMULATION PLAN - 18
<PAGE>   23
not constitute a prohibited transaction pursuant to the Act or Code.

     (b)   Investment of Employee After-Tax. Employee Pre-Tax, Pre-84 and 
Post-83 Match Accounts.  For investment purposes, the Trust may be 
divided into such number and kind of separate and distinct investment 
funds as the Committee may from time to time authorize in its 
absolute discretion ("Investment Funds"); provided, however, that no 
common or preferred stock of a corporation other than that of either 
an Employer or PSA Stock shall be acquired and held for any such 
Investment Fund. Subject to said stock investment limitation, the 
Trust assets allocated to a particular Investment Fund shall be 
invested by the Trustee in such type of property, whether real, 
personal or mixed as the Trustee is directed to acquire and hold for 
such Investment Fund.

     (c)   Direction.  Upon becoming a Participant in the Plan each 
Participant shall direct, on a form prescribed by and filed with the 
Committee, that:

           (i)  the contributions and other amounts credited to his 
Employee After-Tax and Employee Pre-Tax Accounts be invested,  in percentage
multiples authorized by the Committee, in one or more of the following: 
Company Stock, PSA Stock, or one or  more of the Investment Funds authorized
from time to time by  the Committee; and

           (ii) the contributions and other amounts credited to his Pre-84 
and Post-83 Match Accounts be invested, in percentage multiples  authorized by
the Committee, in Company Stock and/or PSA Stock.

     (d)   Failure to Direct.  If a Participant fails to give any such 
investment direction in accordance with Subsection (c) above, all 
contributions and other amounts credited to his Employee After-Tax 
Account, and Employee Pre-Tax Account shall be invested in such money 
market Investment Fund(s) as the Committee shall from time to time in 
its absolute discretion designate, and all contributions and other 
amounts credited to his Pre-84 and Post-83 Match Accounts shall be 
invested in Company Stock.

     (e)  Change of Directed Investments.
                         
          (i)  Future Contributions. A Participant may change his investment 
direction with respect to future contributions to his Pre-Tax  and/or After-Tax
Accounts on such date(s) as set forth at  Section 1.8(a) above (or at such
other times as the Committee  may from time to time in its sole and absolute
discretion  establish upon reasonable notice to Participants), provided that
the written notice of such Participant's change is delivered to the Committee




FINA CAPITAL ACCUMULATION PLAN - 19
<PAGE>   24
by such date prior to the effective date of such change as the 
Committee may from time to time, in its sole and absolute discretion 
establish, also upon reasonable notice of such deadline to 
Participants.

             (ii) Part or All of Account Balances.  In addition, a Participant 
may redirect the investment of part or all of his/her Account  balances, such
change(s) to be processed on such date(s) as  set forth at Section 1.8(b) above
(or at such other times as the  Committee may from time to time, in its sole
and absolute  discretion establish upon reasonable notice of such date(s) to 
the Participants and, provided that the written notice of such  Participant's
change is delivered to the Committee, by such date prior to the effective date
of such change as the Committee may from time to time in its sole and absolute
discretion establish, also upon reasonable notice of such deadline to
Participants.

     (f)   Dividends on Company Stock. All cash dividends, stock 
dividends, stock splits, interest and other amounts received by the 
Trustee with respect to the Company's Stock or PSA Stock held for an 
Employee After-Tax, Employee Pre-Tax, Pre-84 or Post-83 Match Account 
shall be credited to (and, if cash or property other than the 
security from which it was derived, used as soon as practicable to 
purchase said security for), such Account.  At the end of each month 
the portion of any Account invested in a particular Investment Fund 
shall be adjusted to reflect its proportionate share of the fair 
market value of the assets then held by the Trustee for that 
particular Investment Fund.

     (g)   Government Bonds.  Effective upon the attainment of the general 
guarantee base rate maturity for Government Bonds or as soon 
thereafter as administratively feasible, the Trustee shall surrender 
and redeem all Government Bonds.  Coincident with such redemption, 
the Trustee shall provide affected Participants an election to invest 
the proceeds of such surrendered Government Bonds allocable to their 
respective Participant's Account into one or more of the other 
Investment Fund(s).

             If a Participant fails to timely direct the investment 
of the proceeds of the surrendered Government Bonds allocable to such 
Participant's Account, then such proceeds shall be invested in such 
money market Investment Fund(s) as the Committee shall, in its sole 
discretion, have directed for investment of funds for which 
Participant direction was not provided.  No additional monies 
(whether from other Investment Funds or from additional contributions 
to the Plan from any source) may be directed to be invested into 
Government Bonds.




FINA CAPITAL ACCUMULATION PLAN - 20
<PAGE>   25
             The Participant for whose Account such Government Bond was 
previously purchased shall take such steps as the Trustee may  prescribe in
order to effect the surrender and redemption thereof by  the Trustee.

    Section 5.3.  Purchases of Company and PSA Stock. Company Stock 
may be purchased by the Trustee in the open market or from the 
Company.

      If Company Stock is purchased from the Company on a day such 
stock was traded on the open market, the price of such Company Stock 
shall be the closing price of Company Stock on the open market on 
such day.  If such stock was not traded on the open market on the 
date of the purchase from the Company, then the price of such Company 
Stock shall be the closing price of Company Stock on the open market 
on the nearest date next preceding the date of the purchase.  PSA 
Stock shall be purchased by the Trustee in such market or markets as 
may exist from time to time.

      The Trustee shall add to the cost of securities purchased any 
brokerage commissions, transfer taxes and other charges or expenses 
incident thereto, or deduct from the gross proceeds from the sale of 
securities, any such charges incident thereto. The cost to a 
Participant's Account for securities purchased shall be the average 
cost of all securities of the particular issue purchased by the 
Trustee during the calendar month in which the securities shall have 
been purchased for Participants' Accounts.


                             ARTICLE VI

    Section 6.1. Early Retirement Date.  The Retirement Date means 
the date the Participant reaches the age set forth in Section 1.9.

      A Participant who continues employment beyond his Retirement 
Date shall continue to participate herein.

      Section 6.2. Disability Retirement.  "Disability Retirement" 
shall mean the Participant's Termination of Employment because of 
permanent disability.  A Participant will be considered permanently 
disabled for purposes of the Plan if he is considered (or would be 
considered if he were covered thereunder) disabled under the 
Company's long-term disability plan.

<PAGE>   26
     Section 6.3.  Vesting.

     (a)  Employer Contribution Accounts (Pre-84 and Post-83 Match 
Accounts).  Subject to Subsection 6.3(e) and Section 13.3, if a  Participant
incurs 5 consecutive Breaks in Service prior to his  Retirement, Disability
Retirement or death, such Participant shall be  entitled to receive the full
amount credited to his Employee  After-Tax and Employee Pre-Tax Accounts, plus 
a portion of the  amount credited to his Pre-84 and Post-83 Match Accounts, as
set  forth in the applicable schedule in (i) or (ii) below, depending upon  the
number of Years of Service completed by such Participant on the  date of such
separation from employment:

          (i)  Discharge for Cause or Post-Termination Adverse Conduct. If
such Participant was not a Participant on the date this amendment and 
restatement was executed but subsequently became a Participant  and if his
employment with an Employer or Affiliated Company was terminated for Cause, as
defined in Subsection 6.3(e), or such  Participant voluntarily incurred a
termination of employment  whereupon Cause for termination is demonstrated, he
shall be  vested in a percentage of his Pre-84 and Post-83 Match Accounts in
accordance with the following schedule:

                       Years of Service                   Percentage Vested

                        Less than 3                              None
                    3  but less than 4                            20%
                    4  but less than 5                            40%
                    5  but less than 6                            60%
                    6  but less than 7                            80%
                    7  or more                                   100%

          (ii) General Rule.  All other Participants shall be entitled to 
vesting in their Pre-84 and Post-83 Match Accounts in accordance  with the
following schedule:

                       Years of Service                   Percentage Vested

                        Less than 3                               None  
                    3  but less than 4                             60% 
                    4  but less than 5                             80% 
                    5  or more                                    100%

     provided, however, that notwithstanding the foregoing schedules,
a Participant's Pre-84 and Post-83 Match Accounts shall be fully vested on and
after the day such Participant dies, retires by  reason of disability, or
attains the age of 55 years.  The  amount a Participant is entitled to




FINA CAPITAL ACCUMULATION PLAN - 22
<PAGE>   27
receive under this Section shall be distributed to such Participant 
in accordance with the provisions of Articles VI and VII, and the 
balance of such Participant's Pre-84 and Post-83 Match Accounts shall 
be forfeited.

     (b) Employee Pre-Tax and Employee After-Tax Contributions.  A 
Participant shall at all times have a nonforfeitable right in 100% of 
his Employee Pre-Tax Account and his Employee After-Tax Account.

     (c) Forfeitures.
     
         (i)  Upon the earlier of (A) the Participant's Termination 
of Employment and subsequent receipt of a total distribution of the 
Vested portion of his Match Account(s), or (B) the last day of the 
Plan Year during which such Participant incurs five (5) consecutive 
one year Breaks-in-Service, the forfeitable (non-vested) portions of 
his Match Account(s) shall be designated a "forfeiture" as of the 
last day of such Plan Year.

         (ii) The amount of any forfeiture shall be based upon the 
balance in the applicable Accounts as of the Valuation Date 
immediately preceding the date on which the forfeiture occurs.  For 
purposes of this Article VI, a forfeiture shall be charged to the 
applicable Accounts as if it were a distribution on the date the 
forfeiture occurred and, accordingly, that portion of the Account 
which is forfeited shall not share in trust fund earnings.

         (iii) A Participant whose Match Account(s) shall be charged 
with a forfeiture under Subsection 6.3(c)(i) above shall at all times 
have a nonforfeitable right in 100% of the balance in his Match 
Account(s) after the charge for the forfeiture.  Since such 
Participant's nonforfeitable right in any of the Employer 
contributions and forfeitures subsequently allocated to him shall be 
determined in accordance with Subsection 6.3(a), such allocations 
shall be credited to a separate  Match Contribution Account 
established for this purpose.

         (iv) Application of Forfeitures. Any forfeitures resulting 
under the provisions of this Article shall be credited to a 
Forfeiture Account and thereafter applied to reduce the earliest 
subsequent Matching Contributions the Employers would otherwise be 
required to make to the Plan; provided, however, that if the Plan is 
terminated, any forfeited amounts not then so applied shall be 
allocated among and credited to the Post-83 Accounts of the 
Participants in the employ of or on authorized leave of absence from 
an Employer or Affiliated Company on the date of such termination, in 
the proportion that the Basic Compensation received by each




FINA CAPITAL ACCUMULATION PLAN - 23
<PAGE>   28
such Participant during the portion of the then current Plan Year 
prior to said termination bears to the Basic Compensation received by 
all such Participants during the portion of the then current Plan 
Year prior to said termination.

     (d) Reinstatement of Forfeiture/Repayment.

         (i)  If a Participant shall terminate employment and receive a 
total distribution of the vested portion of his Account(s) (whether 
or not he was fully vested in his Match Account(s)) but then is 
reemployed before he has five (5) consecutive One Year Breaks in 
Service after the receipt of his prior distribution, the Participant 
will have a special repayment right.  The Participant may, prior to 
the earlier of the end of the five (5) year period beginning on such 
Participant's resumption of employment or said five (5) consecutive 
One Year Breaks in Service, repay in one single sum payment all, but 
not less than all, of the amount he received as a distribution from 
his Match Account(s).

              If the Participant repays the distribution as provided 
in the first paragraph then the previously forfeited (if any) portion 
of his or her Accounts shall be reinstated as of the last day of the 
Plan Year in which the repayment is made.  However, the repayment and 
reinstatement will be considered made after the trust fund earnings 
have been allocated, which means that the repaid and reinstated 
amounts will not share in income, gains or losses for the Plan 
Year(s) since the date of distribution.  Also, to the extent that all 
or part of the repaid distribution was properly included in the 
Participant's gross income, in a year of distribution, such part 
shall be allocated to the Participant's Employee After-Tax Account as 
of the date of repayment.

         (ii) The amount to be reinstated shall be taken in the Plan 
Year of repayment from the following sources (in each year exhausting 
each source before using a subsequent source):

              (A)    forfeitures;

              (B)    trust fund earnings not specifically otherwise 
allocable, if any.

              (C)    If the above sources are not sufficient to 
completely reinstate one or more Participants' forfeitures, the 
Employer shall make such further contribution as shall be necessary 
to complete the reinstatement.




FINA CAPITAL ACCUMULATION PLAN - 24
<PAGE>   29
              (iii) The amount reinstated shall not be considered an Employer 
Contribution (or an Employee contribution) for purposes of 
calculating a Participant's Annual Additions under Section 4.1 
hereof.

    (e)  Discharge for Cause or Post Termination Adverse Conduct. 
Notwithstanding anything herein to the contrary, any Participant who:

              (i)   has been discharged by the Employer for Cause or

              (ii)  voluntarily incurs a termination of employment 
whereupon Cause for discharge is demonstrated, shall not be entitled 
to any distribution prior to the earlier of:

              (iii) sixty (60) days after the end of the calendar 
year in which either the Participant attains age 55 or terminates 
employment, whichever is later  or

              (iv)  April   1  of the year after the year the 
Participant attains age 70-1/2.

      "Cause" is defined as any misdemeanor or felony or other act 
evidencing theft, embezzlement, extortion, conversion, 
misappropriation or fraud.

    Section 6.4. Commencement of Benefits.

    (a) Distribution Upon Termination, Retirement, Disability and 
Death Benefits Any amount payable to a Participant under the Plan upon his 
Termination of Employment, Retirement or Disability shall be 
distributable to such Participant in a single distribution.  Any 
amount payable under the Plan upon the death of a Participant who was 
married at the time of his death shall be distributed in a single 
distribution to the surviving spouse of such Participant unless such 
Participant had designated otherwise with the written consent of his 
spouse which is witnessed by a member of the Committee or a notary 
public.

    Any amount payable under the Plan upon the death of a 
Participant who is not married or who is married but has designated, 
as provided above, a Beneficiary other than his spouse, shall be 
distributed in a single distribution to the Beneficiary or 
Beneficiaries so designated by the Participant.

    Designation of Beneficiary or Beneficiaries shall be 
made in writing on a form prescribed by the Committee and, when filed 
with the Committee, shall become effective and remain in effect until 
changed by the Participant by the filing of a new Beneficiary 
designation form with the Committee.




FINA CAPITAL ACCUMULATION PLAN - 25
<PAGE>   30
     If an unmarried Participant fails to so designate a Beneficiary, or 
in the event all of the designated beneficiaries are individuals who 
predecease such Participant, then the Committee shall direct the 
Trustee to distribute the amount payable under the Plan in a single 
distribution to the estate of such deceased Participant.

     (b)   Latest Benefit Commencement Date.

           (i)  General Latest Date.  Unless the Participant shall 
otherwise elect pursuant to Subsection 6.4(b) or 6.4(c)(ii), 
distribution of the nonforfeitable portion of his Accounts shall be 
made or commence (in accordance with Article VII), not later than the 
60th day following the last day of the Plan Year during which the 
later of the following events occur:

                (A)   the Participant attains age 55, or

                (B)   the Participant's Termination of Employment.

           (ii) Nonascertainable Distribution.  If the amount of a 
required distribution cannot be ascertained, a distribution 
retroactive to the required commencement date may be made no later 
than 60 days after the earliest date on which the amount of such 
distribution can be ascertained under the Plan.

     (c)   TEFRA/DEFRA Supervening Distribution Requirements.

           (i)  General Life-Time Rule. Notwithstanding any provision 
in this Section or elsewhere in this Plan to the contrary, a 
Participant's entire interest in this Plan shall be distributed to 
him generally not later than the April 1st of the calendar year 
following the calendar year in which he attains age 70-1/2.

           (ii) Grandfather Rule -- Tax Reform Act of 1986. 
Notwithstanding Subsection 6.4(c)(i), in the case of an Employee 
(other than a Five Percent Owner as defined at Article I at anytime 
during the 5-Plan Year period ending in the calendar year in which 
such Five Percent Owner attains age 70), such distribution may begin 
as late as the April 1st of the calendar year following the calendar 
year in which he retires if such individual was both; already age 70 
before January 1, 1988 and was not a Five Percent Owner at any time 
during or after the Plan Year ending with or within the calendar year 
in which such Five Percent Owner attained age 66.

          (iii)  Grandfather Rule -- TEFRA.  Notwithstanding Subsection 
6.4(c)(i) or (ii) above, if such person has had in effect a valid 
designation made under Section 242(b)(2) of the Tax Equity and Fiscal 
Responsibility Act of 1982, such designation shall control.

           (iv)  General Post-Death Rule.

                 (A)   If Benefits Began During Lifetime.  
Notwithstanding any provision in this Plan to the contrary, if a 
Participant's benefits have commenced as provided at Subsection 
6.4(c)(i) above and the Participant dies before his entire interest 
has been distributed to him, the remaining portion of such interest 
will be distributed at least as rapidly as under the method of 
distribution being used under Subsection 6.4(c)(i) above on the date 
of his death.

                 (B)   If Benefits Did Not Begin Before Death - 
Five-Year Rule.  If a Participant dies before his or her 
distributions have commenced, such Participant's entire interest will 
be distributed within five (5) years after his/her death.

                 (C)   Exception To Five-Year Rule.  If the Beneficiary 
is the Participant's spouse, the distribution need only be made by 
the date on which the Participant would have attained age 70-1/2 
provided, however, if the surviving spouse then dies before payments 
are required to begin, then the entire interest must be distributed 
within five (5) years of the surviving spouse's death.

     Section 6.5.  Vesting Years of Service.

     (a)   Vesting Year of Service Defined.  A "Vesting Year 
of Service" means any Plan Year during which an Employee or 
Participant completes 1,000 or more Hours of Service with the Company 
or an Affiliated Company, provided that no "Vesting Year of Service" 
shall be credited for any Plan Year in which the Employee is eligible 
to make but fails to make any Pre-Tax or After-Tax Contribution.

     (b)   Determination of Vesting Years of Service.

           (i)  Post-Break Service - Pre-Break Account.  All of a 
Participant's Vesting Years of Service shall be taken into account; 
provided, however, if a Participant incurs a One Year Break in 
Service during the Plan Year in which his Termination of Employment 
occurs or the immediately following Plan Year, his




FINA CAPITAL ACCUMULATION PLAN - 27
<PAGE>   32
                Vesting Years of Service completed after such One Year Break in 
Service shall be disregarded for purposes of determining his 
forfeitable right in the balance of his pre-break Match Account(s) as 
of the date he incurs five (5) Consecutive One Year Breaks in 
Service.

           (ii) Pre-Break Service.  No Participant shall ever lose 
credit for previously credited Vesting Years of Service (this Plan 
does not contain a vesting "rule of parity").

          (iii)  Vesting Transition Rule.  Notwithstanding Subsection 
6.5(b)(i) above, for purposes of Section 11.2, (with regard to plan 
amendment) all of a Participant's Vesting Years of Service shall be 
taken into account.

           (iv)   Ineligible Person's Hours of Service for Vesting.  For 
purposes of determining Vesting Years of Service, all Hours of 
Service with an Employer or an Affiliated Company shall be counted 
regardless of status as an Ineligible Person.

portion of a Participant's Accounts will be made or commence at the 
time prescribed by Article VI in a single distribution.

     (b)   Government Bonds.  The portion of any Account invested in 
Government Bonds will be distributed in the form of such bonds or in 
cash, or in any combination thereof, as determined by the Committee 
in its absolute discretion.

     (c)   Company Stock.  The portion of any Account invested in Company 
Stock will be distributed in the form of such stock or in cash, or in 
any combination thereof, as determined by the Committee in its 
absolute discretion.

     (d)   PSA Stock. The portion of any Account invested in PSA Stock or 
PSA American Depository Receipts ("ADR's") will be converted into 
cash and distributed in the form of cash or in the form of Company 
Stock, or in any combination thereof, as determined by the Committee 
in its absolute discretion.  Any Company or PSA Stock or PSA ADR's 
which is to be converted into cash for distribution to a Participant 
or beneficiary shall




FINA CAPITAL ACCUMULATION PLAN - 28
<PAGE>   33
be sold by the Trustee in the open market during the month preceding 
the date as of which such withdrawal or other distribution occurs.  
The amount of cash to be distributed to the Participant or 
beneficiary with respect to such Company or PSA Stock or PSA ADR's 
shall be determined on the basis of the average net proceeds per 
share (i.e., gross proceeds from the sale less any brokerage 
commissions, transfer taxes and other expenses incident thereto) 
realized by the Trustee upon such sales during said month.  In lieu 
of making such sales on the open market, the Trustee in its 
discretion may match such sales with purchases to be made for such 
month pursuant to the Plan, with the prices of any such matched sales 
and purchases being determined in the same manner as provided in 
Section 5.3 for determining the price of Company Stock purchased from 
the Company.

      The portion of any Account invested in an Investment Fund 
authorized by the Committee will be converted into and distributed in 
the form of cash.

      Section 7.2.  Date for Determining Value of Account Balance. 
Notwithstanding the date or dates upon which distributions from a 
Participant's Accounts are made, such distributions shall be based 
upon the value of his Accounts as of the immediately preceding 
Valuation Date as determined from time to time by the Committee.

      Section 7.3.  Qualified Domestic Relations Order.  The 
provisions of this Article shall not apply to the extent they 
conflict with a Qualified Domestic Relations Order as determined by 
the Committee pursuant to its Qualified Domestic Relations Order 
procedure.

      Section 7.4.  Effect of Death of Beneficiary.  In the event any 
person entitled to receive death benefits survives the Participant 
but dies prior to his/her receipt of all of the benefits to which 
he/she is entitled, the balance of such benefits shall be paid (in 
accordance with Article VI) to such person's estate.

      Section 7.5.  Minors and Persons Under Other Legal Disability. 
Distributions to a minor or a person under other legal disability 
shall be made by the Trustee at the direction of the Committee:

      (a)    to either one or both of the natural or adoptive 
parents, the legal guardian or conservator of such person, or any 
other person who, as a matter of local law, is responsible for the 
financial affairs of the minor; or

      (b)    to a custodian for such person under any Uniform Gifts 
to Minors Act or Gifts of Securities to Minors Act.

fiduciary with respect to the Plan) shall discharge its duties 
hereunder solely in the interest of the Participants and their 
beneficiaries and --

    (a) for the exclusive purposes of:

          (i)  providing benefits to Participants and their 
beneficiaries; and

          (ii)  defraying reasonable expenses of administering the 
Plan and Trust; and

    (b) with the care, skill, prudence and diligence under the 
circumstances then prevailing that a prudent man acting in a like 
capacity and familiar with such matters would use in the conduct of 
an enterprise of like character and with like aims.

    Section 8.5. Information to be Furnished to Committee. The 
Employer shall furnish the Committee such data and information as it 
may require. The records of the Employer shall be determinative as to 
an Employee's or Participant's period of employment, Termination of

persons being designated and shall set forth the rights, powers and 
duties being delegated.  Either the Company or the Committee may

notification to the person or persons to whom the delegation has been

or to the persons serving as the Committee (if the revocation is made 
by the Company).

     (b)  Copies of all instruments allocating or delegating rights, 
powers and duties of the Committee or the revocation thereof shall be 
provided to the Trustee by the Company.

    Section 8.8. Indemnification of the Committee by the Company. To 
the extent permitted by law, the Company hereby agrees to indemnify a 
member of the Committee who is also an Employee of the Employer for 
and to hold him harmless against any and all liabilities, losses, 
costs or expenses (including legal fees and expenses) of whatsoever 
kind and nature which may be imposed on, incurred by or asserted 
against him at any time by reason of his service under the Plan if he 
did not act dishonestly or otherwise in willful violation of the law 
under which such liability, cost or expense arises.  This indemnity 
shall not preclude such other indemnities as may be available under 
insurance purchased or provided by the Company or under any bylaw, 
agreement, action of stockholders or disinterested directors or 
otherwise, to the extent permitted by law. Payments of any indemnity, 
expenses or fees under this Section shall be made solely from assets 
of the Company and shall not be made directly or indirectly from 
Trust Fund assets.

    Section 8.9. Limitation on Responsibilities.  The functions of 
any agent, attorney, actuary, accountant or other person engaged 
pursuant to Section 8.2 and Qualified Investment Manager, if any, 
engaged pursuant to Section 8.10 shall be limited to the specific 
services and duties for which they are engaged, and such persons 
shall have no other duties or obligations under the Plan or Trust. 
Such persons shall exercise no discretionary authority or control 
respecting management of the Plan and Trust and, unless engaged as 
the Qualified Investment Manager, shall exercise no authority or 
control respecting management or disposition of the assets of the 
Trust. A member of the Committee who is an Employee shall be free 
from all liability for his acts and conduct in the administration of

however, that the foregoing shall not relieve him from any 
responsibility or liability for any responsibility, obligation or 
duty he may have pursuant to the Act.

the Company, and the Qualified Investment Manager and shall set forth 
the rights, powers and duties of the Qualified Investment Manager and 
contain an acknowledgment by the Qualified Investment Manager that he 
is a fiduciary with respect to the Plan and Trust.  The Company may 
revoke the appointment of a Qualified Investment Manager at any time

                             ARTICLE IX

          CLAIM FOR BENEFITS PROCEDURE AND LAPSED BENEFITS

      Section 9.1.  Claim for Benefits.  Any claim for benefits under 
the Plan shall be made in writing to the Committee.  If such claim 
for benefits is wholly or partially denied by the Committee, it 
shall, within a reasonable period of time, but no later than 60 days 
after receipt of the claim, notify the claimant of the denial of the 
claim.  Such notice of denial shall be in writing and shall contain 
(a) the specific reason or reasons for denial of the claim, (b) a 
specific reference to the pertinent Plan and, if applicable, Trust 
provisions upon which the denial is based, (c) a description of any 
additional material or information necessary for the claimant to 
perfect the claim, together with an explanation of why such material 
or information is necessary and (d) an explanation of the Plan's 
claims review procedure.

      Section 9.2.  Request for Review of a Denial of a Claim for 
Benefits. Upon the receipt by the claimant of the written notice of 
denial of the claim or if the claim has not been granted within 60 
days, the claimant may, not later than 90 days thereafter, file a 
written request with the Committee that the Committee conduct a full 
and fair review of the denial of the claimant's claim for benefits, 
which shall include a hearing if deemed necessary by the Committee.  
In connection with the claimant's appeal of the denial of his claim, 
he may review pertinent documents and may submit issues and comments 
in writing.

      Section 9.3.  Decision Upon Claim for Review of a Denial of a 
Claim for Benefits.  The Committee shall render a decision on the 
claim review promptly, but not later than 60 days after the receipt 
of the claimant's request for review, unless special circumstances 
(such as the need to hold a hearing, if necessary) require an 
extension of time for processing, in which case the 60 day period (by 
written notice to the claimant within the 60-day period) shall be 
extended to 120 days. Such decision shall (a) include specific 
reasons for the decision, (b) be written in a manner calculated to be 
understood by the claimant and (c) contain specific references to the 
pertinent Plan and, if applicable, Trust provisions upon which the 
decision is based.  The decision of the Committee shall be final and 
binding on all persons and shall not be




FINA CAPITAL ACCUMULATION PLAN - 33
<PAGE>   38
overturned by any court unless said court first finds such decision 
to be arbitrary and capricious.

      Section 9.4.  Domestic Relations Order.  The Committee shall 
from time to time establish such written procedures for evaluating 
and determining the status of any domestic relations order and shall 
give due notice to any affected parties (Participants and alternate 
payees as defined at Code Section 414(p)(8)), as required by law.  
Notwithstanding anything herein to the contrary, an alternate payee 
shall have no right to direct the investment of a Participant's 
Account.

      Section 9.5.  Lapsed Benefits.

      (a)    General.  If the Committee mails by registered or 
certified mail, return receipt requested, to a Participant or 
beneficiary entitled to a distribution hereunder at his last known 
address, a notification that he is so entitled and said notification 
is returned as being undeliverable because the addressee cannot be 
located at said address, and if, by the last day of the Plan Year 
coinciding with or immediately following the third (3rd) anniversary 
of the date as of which such person first could not be located, said 
person has not informed the Committee of his whereabouts, his entire 
interest in this Plan shall become a forfeiture and shall be 
reallocated as provided in Subsection 9.5(c).  Thereafter such person 
shall have no further right or interest therein except as provided in 
Section 9.5(b).

      (b)    Reinstatement.  If a Participant or a beneficiary prior 
to the Plan Year in which the Plan and Trust terminate, duly claims 
and proves entitlement to a benefit which otherwise lapsed pursuant 
to Subsection (a) above, such benefits as shall then be due, 
unadjusted for trust fund earnings and/or losses subsequent to the 
date of forfeiture, shall be paid by the Plan as soon as is 
administratively feasible.

      (c)    Source of Reinstatement.  The reinstatement of lapsed 
benefits shall first be derived from forfeitures which otherwise 
occur in the Plan Year of the reinstatement pursuant to Subsection 
(b) above and if such forfeitures are not sufficient, such 
reinstatement to the extent necessary shall then next be made from 
trust fund earnings (if any) which are not specifically allocable to 
Participant directed Accounts, and if further funds are necessary 
then from Employer contributions.

       (d)   Disposition of Lapsed Benefits in Plan Year and Trust Termination.
In  the event a Participant's entire interest in the Plan is forfeitable  and
lapses pursuant to Subsection 9.5(a) in the Plan Year in which  both the Plan
and Trust terminate, if the Committee after having  complied with the notice
requirements at Subsection 9.5(a) is unable  to locate Participants (or their
beneficiaries) entitled to a  distribution hereunder by the close of such Plan
Year, then the  following rules of this




FINA CAPITAL ACCUMULATION PLAN - 34
<PAGE>   39
Subsection 9.5(d) shall supersede so much of the rules of Subsections 
9.5(a), (b) and (c) as conflict herewith.  Such person's entire 
interest in the Plan shall be remitted under appropriate transmittal 
to such appropriate state or commonwealth agency responsible for 
unclaimed assets and escheat (as provided below), to be held and 
disposed of by them in accordance with the laws of such state or 
commonwealth.  Once so remitted to such state or commonwealth, any 
such Participant (or other person claiming by, through, or under the 
rights of such Participant) shall have no further claim against this 
Plan and the Trust and such person's rights to any such funds 
otherwise distributable from the Plan and the Trust shall solely be 
pursuant to such rights and legal remedies as exist under the laws of 
such state or commonwealth with respect to funds so remitted, as from 
time to time exists.

      It is intended that this provision comply with the requirements of 
Internal Revenue Code Section 411 and in particular regulation 
Section 1.411(a)-4(b)(6) regarding escheat of benefits to a state, 
thus permitting orderly cessation of all Plan and Trust activity as 
the Trustees deem is consistent with the greatest protection of the 
interest of Participants in the Plan.  In the event of distributions 
to a state or commonwealth pursuant to this Subsection (d), so much 
of the foregoing Section 9.5 as is inconsistent herewith shall be 
deemed null and void.

      The appropriate state or commonwealth to which assets 
shall be remitted hereunder and thereafter escheat, shall be the 
state or commonwealth shown on the last address record with the 
Employer as the address of the Participant; and if more than one 
concurrent address is shown, the one presumed by the Committee to be 
the permanent residence.


                              ARTICLE X

                      LIMITATION UPON REVERSION

      Section 10.1. Exclusive Benefit.  Except as otherwise provided 
by the Code and this Article, no part of the corpus or income of the 
Trust shall revert to the Company or be used for, or directed to, 
purposes other than for the exclusive benefit of Participants and 
their beneficiaries and defraying reasonable expenses of 
administering the Plan and Trust.

      Section 10.2. Permissible Reversions.

      (a)    Mistake of Fact.  If an Employer contribution is made to 
the Trust due to a good faith mistake of fact, then within one year 
of the date of payment of such Employer contribution to the Trust an 
amount equal to the excess of (i) the amount of such Employer 
contribution over (ii) the amount which would have been contributed 
had a mistake of fact not




FINA CAPITAL ACCUMULATION PLAN - 35
<PAGE>   40
occurred (the "Excess Contribution"), shall be returned to the 
Employer. If the trust incurred a loss attributable to such Excess 
Contribution, then the amount of such Excess Contribution shall be 
reduced by such loss.

      (b)    Disallowance of Deduction.  If an Employer contribution 
is made to the Trust conditioned upon its deductibility under Section 
404 of the Code and a good faith mistake is made in determining the 
deductibility of such contribution, then within one year of the date 
of disallowance of the deduction of such Employer contribution to the 
Trust an amount equal to the excess of (i) the amount of such 
Employer contribution over (ii) the amount which would have been 
contributed had a mistake not occurred in determining the 
deductibility of such contribution (the "Excess Contribution"), shall 
be returned to the Employer.  If the trust incurred a loss 
attributable to such Excess Contribution, then the amount of such 
Excess Contribution shall be reduced by such loss.

      (c)    Charge to Accounts - Limitation on Excess Contribution. 
If a Valuation Date has occurred between the date of an Excess 
Contribution and the date of its return pursuant to Subsections 
10.2(a) or (b), then the Match Account(s) of each Participant shall 
be charged with a portion of the Excess Contribution based upon the 
proportion which the Employer Contribution allocated to each 
Participant on such Valuation Date bears to the total Matching 
Contribution allocated on such date; provided, however, that if the 
charge to the Match Account(s) of any Participant would cause the 
balance of such account to be reduced to less than the balance which 
would have been in such Account had the Excess Contribution not been 
contributed, then the amount of the Excess Contribution shall be 
limited so as to avoid any such reduction.

                             ARTICLE XI

                              AMENDMENT

      Section 11.1. In General.  The Company shall have the right and 
power at any time and from time to time to amend this Plan, in whole 
or in part, on behalf of all Employers.  With the consent of the 
Company, each Employer shall have the right and power at any time and 
from time to time to amend this Plan, in whole or in part, with 
respect to the Plan's application to the Participants of the 
particular amending Employer and the assets held in the Trust for 
their benefit, or to transfer such assets or any portion thereof to a 
new trust for the benefit of such Participants. The Employers shall 
in writing notify the Committee of any amendment or change in the 
provisions of the Plan.  Notwithstanding the foregoing, no amendment 
shall:

      (a)    vest in any Employer, directly or indirectly, any 
interest, ownership or control in any assets of the Trust;




FINA CAPITAL ACCUMULATION PLAN - 36
<PAGE>   41
      (b)   with respect to an Employee who is a Participant on the later 
of the date such amendment is adopted or effective, have the effect 
of reducing his nonforfeitable percentage as of such date in his 
Match Account(s); provided, however, that any rights accrued or 
vested under the Plan and Trust may be adjusted among Participants by 
amendments made prior to securing or in order to secure the continued 
approval of the Plan and Trust by the Internal Revenue Service as a 
qualified plan and exempt trust under Sections 401(a) and 501(a), 
respectively, of the Code; or

      (c)   affect the rights, responsibilities or duties of the 
Trustee without the Trustee's written consent.  A copy of any 
amendment shall be delivered to the Committee and the Trustee.

      Section 11.2. Amendments to Vesting Schedule.

      (a)   Availability of Election.  If the Plan's vesting schedule 
is amended, each Participant whose nonforfeitable percentage in his 
Match Account(s) is determined under such schedule as amended, and 
who has completed at least three Vesting Years of Service (prior to 
the expiration of the election period described in this Section) may 
irrevocably elect to have such nonforfeitable percentage determined 
under the Plan without regard to such amendment.  The Committee shall 
provide each such Participant with written notice of the adoption of 
the amendment and the availability of the election.

      (b)    Election Requirements. The election referred to in 
Subsection (a) must be in writing and must be filed with the 
Committee during the period beginning on the date the amendment is 
adopted and ending on the latest of the following:

              (i)   the date 60 days after the date the amendment is 
adopted;

              (ii)  the date 60  days after the date the amendment 
becomes effective; or

              (iii) the date 60 days after the date the Participant 
is issued written notice of the amendment by the Company or the 
Committee.

                             ARTICLE XII

                  TERMINATION OF THE PLAN AND TRUST

      Section 12.1.  Right to Terminate Plan and Trust.  Each 
Employer reserves the right to terminate the Plan and Trust with 
respect to its sponsorship at any time by written notification to the 
Committee and the Trustee.  Upon receipt of such notice, the Trustee 
shall proceed to pay all liabilities of the Trust other than to




FINA CAPITAL ACCUMULATION PLAN - 37
<PAGE>   42
Participants or their beneficiaries.  On a date mutually determined 
by the Committee and the Trustee, the Committee shall make the 
appropriate Account adjustments as if such date were a Valuation 
Date.  As soon thereafter as practicable, the Trustee shall 
completely distribute each affected Participant's Accounts to him or 
his beneficiaries.

      Section 12.2.  Right to Discontinue Contributions.  Each 
Employer reserves the right to permanently discontinue its own 
contributions to the Trust at any time by written notification to the 
Committee and the Trustee.  Thereafter, the provisions of the Plan 
and Trust shall continue in full force and effect (other than the 
provisions relating to contributions by such Employer) until the 
benefits of all Participants and beneficiaries have been distributed 
to them in accordance with the provisions of the Plan, at which time, 
as to such Employer(s), the Plan and Trust shall terminate.

      Section 12.3.  Vesting Upon Termination of Plan or Complete 
Discontinuance of Contributions.  Upon the termination of the Plan or 
the complete discontinuance of contributions by an Employer, each 
Participant employed by such Employer shall have a nonforfeitable 
right in 100% of his/her Match Account(s).  Upon a partial 
termination of the Plan (as determined under the facts and 
circumstances then applicable) each affected Participant shall have a 
nonforfeitable right to 100% of his/her Match Account(s).

      Section 12.4. Merger or Consolidation of Plan and Trust. 
Neither the Plan nor the Trust may be merged or consolidated with, 
nor may their assets or liabilities be transferred to, any other plan 
or trust, unless each Participant would receive a benefit immediately after 
the merger, consolidation or transfer which is equal to or greater 
than the benefit he would have been entitled to receive immediately 
before the merger, consolidation or transfer (if the Plan and Trust 
had then terminated).

                      STAND-BY TOP HEAVY RULES

    Section 13.1. Determination of Top Heavy or Super Top Heavy 
Status.

      (a)    Top Heavy.  This Plan shall be a Top Heavy Plan for any 
Plan Year commencing after December 31, 1983 in which, as of the 
Determination Date, (1) the Present Value of Accrued Benefits of Key 
Employees and/or (2) the sum of the Aggregate Accounts of Key 
Employees under this Plan and any plan of a Required Aggregation 
Group, exceeds sixty percent (60%) of the Present Value of Accrued 
Benefits and/or the Aggregate Accounts of all Participants under this 
Plan and any plan of a Required Aggregation Group.




FINA CAPITAL ACCUMULATION PLAN - 38
<PAGE>   43
     (b) Super Top Heavy. This Plan shall be a Super Top Heavy Plan 
for any Plan Year commencing after December 31, 1983 (and such Plan 
Year shall be a "Super Top Heavy Plan Year") in which, as of the 
Determination Date, (1) the Present Value of Accrued Benefits of Key 
Employees and/or (2) the sum of the Aggregate Accounts of Key 
Employees under this Plan and any plan of a Required Aggregation 
Group, exceeds ninety percent (90%) of the Present Value of Accrued 
Benefits and/or the Aggregate Accounts of all Participants under this 
Plan and any plan of a Required Aggregation Group.

     (c) Effect of Change in Status to Non-Key Employee.  If any 
Participant (or Beneficiary) is a Non-Key Employee (after first 
taking into account the fact that one is a Key Employee if he was a 
Key Employee in any of the four (4) preceding Plan Years) for any 
Plan Year, but such Participant (or Beneficiary) was a Key Employee 
for any prior Plan Year, such Participant's Aggregate Account Balance 
and/or Present Value of Accrued Benefit shall not be taken into 
account for purposes of determining whether this Plan is a Top Heavy 
Plan or Super Top Heavy Plan (or whether any Aggregation Group which 
includes this Plan is a Top Heavy Aggregation Group).

     (d) Benefits Not Considered if No Service Performed for Last 
Five (5) Years. If an individual has not performed any service for 
the Company at any time during the five (5) year period ending on the 
Determination Date, any Accrued Benefit or Account of such individual 
shall be ignored for determining Top Heavy or Super Top Heavy status.

     (e) Aggregate Account.  A Participant's Aggregate Account as of 
the Determination Date is the sum of:

         (i)  the value (as of the Plan's most recent Valuation Date 
occurring within the twelve (12) month period ending on the 
Determination Date) of all accounts maintained on behalf of the 
Participant, whether attributable to Employer or Employee 
Contributions; plus

         (ii) an adjustment for any Employer contributions due as of the 
Determination Date (including, in the case of Plans subject to the 
minimum funding requirements of Code Section 412, contributions 
waived in prior years). Such adjustment shall be the amount of any 
Employer contribution actually made after the Valuation Date, but 
before the Determination Date, provided, however, that for the first 
Plan Year, such adjustment shall also reflect the amount of any 
Employer contribution made after the Determination Date that is 
allocated as of a date in that first Plan Year; plus

         (iii) Any Plan distributions made within the Plan Year, that 
includes the Determination Date or within the four (4) preceding Plan




FINA CAPITAL ACCUMULATION PLAN - 39
<PAGE>   44
Years.  However, in the case of distributions made after the 
Valuation Date and prior to the Determination Date, such 
distributions are not included as distributions for Heavy or Super 
Top Heavy purposes to the extent that such distributions are already 
included in the Participant's Aggregate Account balance as of the 
Valuation Date.  Notwithstanding anything herein to the contrary, all 
distributions, including distributions made prior to January 1, 1984, 
if any, will be counted; plus

           (iv)  Any Employee contributions, whether voluntary or 
mandatory. However, amounts attributable to tax deductible qualified 
voluntary employee contributions (as had been provided for at 
repealed Section 219(e)(2) of the Code) shall not be considered to be 
a part of the Participant's Aggregate Account Balance.

           (v)  With respect to unrelated rollovers and plan-to-plan 
("portability") transfers (ones which are both initiated by the 
Employee and made from a plan maintained by one company to a plan 
maintained by another company), if this Plan provides for rollovers 
or plan-to-plan transfers, it shall always consider such rollover or 
plan-to-plan transfers as a distribution for the purposes of this 
Section.  If this Plan is the plan accepting such rollovers or 
plan-to-plan transfers, it shall not consider such rollovers or 
plan-to-plan transfers accepted after December 31, 1983, as part of 
the Participant's Aggregate Account balance.  However, rollovers or 
plan-to-plan transfers accepted prior to January 1, 1984, shall be 
considered as part of the Participant's Aggregate Account balance.

           (vi)   With respect to related rollovers and plan-to-plan 
transfers (ones either not initiated by the Employee or made to a 
plan maintained by the same company), if this Plan made the rollover 
or plan-to-plan (portability) transfer, it shall not be counted as a 
distribution for purposes of this Section; if this Plan is the plan 
accepting such rollover or plan-to-plan (portability) transfer, it 
shall be treated as part of the Participant's Aggregate Account 
balance, irrespective of the date on which such rollover or 
plan-to-plan (portability) transfer is received.

           (vii)   Notwithstanding Subsection 13.1(e)(iii), or anything 
else herein to the contrary, benefits paid on account of death which 
exceed the present value of accrued benefits existing immediately 
prior to death will not be treated as distributions inclusive for 
these purposes.

     (f)   Aggregation Group means either a Required Aggregation Group or 
a Permissive Aggregation Group as hereinafter determined.




FINA CAPITAL ACCUMULATION PLAN - 40
<PAGE>   45

                (i) Required Aggregation Group.  In determining a Required 
Aggregation Group hereunder, each plan of the Company in which a Key  Employee
is a participant, and each other plan of the Company which  enables any plan in
which a Key Employee participates to meet the  requirements of Code Sections
401(a)(4) (includes comparability of  benefits or contributions) or 410, will
be required to be aggregated.   Such group shall be known as a "Required
Aggregation Group."

             In the case of a Required Aggregation Group, each plan 
in the group will be considered a Top Heavy Plan or Super Top Heavy 
Plan (respectively) if the Required Aggregation Group is a Top Heavy 
Aggregation Group or a Super Top Heavy Aggregation Group 
(respectively).  No plan in the Required Aggregation Group will be 
considered a Top Heavy Plan or Super Top Heavy Plan if the Required 
Aggregation Group is not a Top Heavy Group or Super Top Heavy Group 
(respectively).

             (ii)   Permissive Aggregation Group. The Company may also 
include any other plan not required to be included in the Required 
Aggregation Group, provided the resulting group, taken as a whole, 
would continue to satisfy the provisions of Code Section 401(a)(4) 
(including comparability of benefits or contributions) and 410. Such 
group shall be known as a "Permissive Aggregation Group."

             In the case of a Permissive Aggregation Group, only a 
plan that is part of the Required Aggregation Group will be 
considered a Top Heavy Plan if the Permissive Aggregation Group is a 
Top Heavy Group.  No plan in the Permissive Aggregation Group will be 
considered a Top Heavy Plan if the Permissive Aggregation Group is 
not a Top Heavy Aggregation Group.

             (iii)  Method of Aggregating Plans.  First the Present Value and 
Sum of the Aggregate Accounts is determined separately for each plan  as of
each plan's Determination Date.  The plans are then aggregated  by adding the
results of each plan as of the Determination Dates for  such plans which fall
within the same calendar year.  The combined  results will determine whether or
not a Top Heavy Aggregation Group  exists.

      (g)   Present Value of Accrued Benefit.  In the case of a Defined 
Benefit Plan(s), a Participant's Present Value of Accrued Benefits 
shall be determined under a uniform method that applies to all 
defined benefit plans maintained by the Employer. If no single accrual 
method is used




FINA CAPITAL ACCUMULATION PLAN - 41
<PAGE>   46
by all such plans, the method shall be determined as if the benefits 
accrued at the slowest accrual rate permitted under Section 
411(b)(1)(C) of the Code.

     (h)   "Top Heavy Aggregation Group" means an Aggregation Group in 
which, as of the Determination Date, the sum of:

           (i)  the Present Value of Accrued Benefits of Key Employees 
under all Defined Benefit Plans included in the group, and

           (ii) the Aggregate Accounts of Key Employees under all 
Defined Contribution Plans included in the group, exceeds sixty 
percent (60%) of a similar sum determined for all Participants.  If 
the foregoing determined percentage exceeds ninety percent (90%), the 
Aggregation Group shall be deemed a Super Top Heavy Aggregation 
Group.

     Section  13.2.  Minimum Allocation Requirement for Top Heavy Plan.

     (a)   Minimum Annual Allocation.  Notwithstanding any provision at 
Article IV to the contrary, for any Top Heavy Plan Year, the 
following Minimum Annual Allocation shall be credited to the Account 
of each Non Key Employee unless such minimum annual allocation 
requirement is otherwise satisfied by another plan of the Company or 
by another plan in the Aggregation Group.  Minimum Annual Allocation 
shall mean the Primary Minimum Annual Allocation or both the Primary 
Minimum Annual Allocation and the Secondary Minimum Annual Allocation 
as the context so requires.  Compensation as used in this Section 
shall mean the Participant's Limitation Year Compensation as defined 
in Section 4.3(e).

     (b)   The Primary Minimum Annual Allocation, consisting of the sum of 
Employer Contributions and Forfeitures allocated to the Participant's 
Account shall be equal to the lesser of (i) 3% of each Non-Key 
Employee's Compensation or (ii) the largest percentage allocation of 
Employer Contributions (including Employee Pre-tax Contributions and 
Match Contributions) and Forfeitures allocated to the Account of any 
Key Employee where such percentage allocation is determined as a 
percentage of the first $200,000 (or such larger amount as may be 
permitted to be considered by regulation) of such Key Employee's 
Compensation.




FINA CAPITAL ACCUMULATION PLAN - 42
<PAGE>   47
     (c)   Secondary Minimum Annual Allocation for Top Heavy Plans in 
Order to Retain Higher Code Section 415 Plan Limits (Other Than Super 
Top Heavy Plans). If a Key Employee is a Participant in both a 
defined contribution plan and a defined benefit plan that are both 
plans of a Top Heavy Aggregation Group (but neither of such plans is 
a Super Top Heavy plan), the defined contribution and the defined 
benefit fractions set forth in Subsections 4.2(b) and (c) shall 
remain unchanged as provided for at Subsection 4.2(e) provided that 
for each Top Heavy Plan Year in which one or more Key Employees is a 
Participant in both the defined benefit and defined contribution 
plans which are part of a Top Heavy Aggregation Group each Non-Key 
Employee Participant's Account receives a Secondary Minimum Annual 
Allocation in addition to the Primary Minimum Annual Allocation 
equal to one percent (1%) of the such Non-Key Employee's 
Compensation.

     (d)   Minimum Annual Allocation Despite Ineligibility for Normal 
Allocations.  For any Top Heavy Plan Year, the minimum allocations 
set forth above shall be allocated to the Participant's Account of 
all Non-Key Employees who are Participants and who are employed by an 
Employer on the last day of the Plan Year, including Non-Key 
Employees who (i) failed to be credited with a Year of Service, or 
(ii) declined to make mandatory contributions (if required) to the 
Plan.

     (e)   Nonduplication of Minimum Contributions and Annual Benefits. If 
a Non-Key Employee participates in both a defined benefit plan and a 
defined contribution plan included in a Top Heavy Aggregation Group, 
the Employer is not required to provide such Non-Key Employee with 
both the full and separate Minimum Annual Benefits and the full and 
separate Minimum Annual Allocations.  By elevating the Minimum Annual 
Allocation for any such Non-Key Employee to five percent (5%) (seven 
and one-half percent (7 1/2%) in order to retain the higher 1.25 
factor of Subsection 4.2(e)) of such Non-Key Employee's compensation, 
both plans will be presumed to satisfy the Code Section 416 minimums. 
The first time the issues raised by this Subsection become relevant, 
the Company shall select, by Board Resolution (which choice cannot 
thereafter be changed absent a plan amendment) whether to elevate the 
Minimum Annual Addition to five percent (5%) or seven and one-half 
percent (7-1/2%) or to adopt the floor offset approach described in 
regulation 1.416-1. If a Non-Key Employee participates in two defined 
contribution plans included in a Top Heavy Aggregation Group, only 
one such plan must provide the defined contribution Minimum 
Allocations.  The Committee shall arrange coordination between plans 
to the extent permitted by law.

    Section 13.3. Top Heavy Vesting Rule.

    (a)   Top Heavy Vesting Schedule Overrides Plan Regular Vesting 
Schedule.  Notwithstanding the vesting schedules at Subsection 
6.3(a)(i) and (ii), for any Top Heavy Plan Year, the vested portion 
of any Participant's Match Account(s) (including amounts, if any, 
credited to such Account(s) prior to the effective date of Code 
Section 416 and prior to the Plan becoming Top Heavy and regardless 
of whether a similar schedule applies to such Participant's interest 
in any other plan) shall be determined on the basis of the 
Participant's number of Vesting Years of Service according to the 
following schedule:

                    Vesting Schedule

            Vesting Years of Service                       Percentage

           Less than 2 years                                   0%
           2 years but less than 3                            20%
           3 years but less than 4                            60%
           4 years but less than 5                            80%
           5 years or more                                   100%

    (b)    Discretion to Discontinue Top Heavy Schedule For 
Non-Top-Heavy Plan Years. If in any Plan Year subsequent to a Top 
Heavy Plan Year, the Plan ceases to be a Top Heavy Plan, the 
Committee may, in its sole and absolute discretion, elect to:  (1) 
continue to apply the Top Heavy vesting schedule at Subsection 
13.3(a) above, in determining the Vested portion of any Participant's 
Match Account(s) balance(s), or (2) revert to the vesting schedule in 
effect before this Plan became a Top Heavy Plan.  Any such reversion 
shall be treated as a Plan Amendment pursuant to the terms of Code 
Section 411(a)(1) as set forth at Section 11.2 of the Plan.

      (c)    The Top Heavy vesting rule at Subsection 13.3(a) does 
not apply to the interest of any Participant who has not actually 
worked an Hour of Service after the Plan becomes Top Heavy.

                             WITHDRAWALS

      Section 14.1. Withdrawals by Participants.  By filing a written 
notice of withdrawal with the Committee prior to the end of any 
month, a Vested Participant may, subject to the limitations at 
Section 14.1(d) and (e) below, withdraw:




FINA CAPITAL ACCUMULATION PLAN - 44
<PAGE>   49
      (a)    all or any portion of the amount credited to his 
Employee After-Tax Account as of the end of such month; and

      (b)    if no amount remains credited to his Employee After-Tax 
Account following such withdrawal, all or any portion of the vested 
amount credited to his Pre-84 Match Account as of the end of such 
month; and

      (c)    if such Participant has either attained the age of 
59-1/2 years or is not in the employ of or on authorized leave of 
absence from an Employer or Affiliated Company, all or any portion of 
the amounts credited to his Employee Pre-Tax and Employee After-Tax 
Match Accounts as of the end of such month;

      (d)    provided, however, that no withdrawals may be made on or 
after July 1, 1991, for any sum less than five hundred dollars 
($500.00) and provided further that a Participant may not obtain more 
than two (2) withdrawals in any twelve (12) consecutive month period 
nor more than five (5) withdrawals in any sixty (60) month period; 
and

      (e)    if the Partially Vested Participant making a withdrawal 
pursuant to this Section is in the employ of or on authorized leave 
of absence from an Employer or Affiliated Company at the end of the 
month as of which such withdrawal is made, the vested portion of such 
Participant's Pre-84 Match Account and/or Post-83 Match Account, from 
which the withdrawal was made, shall at all times after the making of 
such withdrawal be determined by the formula P(AB+D)-D, where P is 
such Participant's vested percentage at the relevant time, AB is the 
value of said Account at the relevant time, and D is the total amount 
previously withdrawn from said Account.

      Section 14.2. Loans to Participants.  Subject to such 
conditions and limitations as the Committee may from time to time 
prescribe for application to all Participants on a uniform basis to 
ensure repayment, at the request of a Participant the Committee shall 
direct the Trustee to loan to such Participant from his or her 
Employee Pre-Tax Account an amount of money which does not exceed the 
least of: (a) $50,000 reduced by the total outstanding balance of all 
other loans to such Participant from the Trust, or the highest 
outstanding balance of all such loans for the one year period ending 
the day before the date of the loan (if greater), or (b) one-half of 
such Participant's Vested Interest under the Plan (but excluding in 
such determination such Employee's After-Tax Account), or (c) the 
amount that may otherwise be loaned to such Participant without being 
treated under the provisions of Section 72(p) of the Code as having 
been received by such Participant as a distribution under the Plan.

      Any such loan made to a Participant shall be made from proceeds 
liquidated from the Participant's Account in a priority from time to 
time established by the Committee, shall be evidenced by a promissory 
note payable to the Trustee, shall bear




FINA CAPITAL ACCUMULATION PLAN - 45
<PAGE>   50
a reasonable rate of interest, shall be secured by the borrowing 
Participant's Vested Interest under the Plan and shall be repayable 
in equal installments (not less frequently than quarterly) over a 
period not to exceed five (5) years from the date of the loan; 
provided, however, that if such loan is to be used to acquire or 
Construct any dwelling unit which, within a reasonable time, is to be 
used as a principal residence of the Participant, the Committee may 
direct the Trustee to make such loan repayable over such period 
greater than five (5) years.

      Any provision of this Plan to the contrary notwithstanding, (a) 
the promissory note evidencing any such loan shall be held by the 
Trustee as a segregated investment allocated to and made solely for 
the benefit of the Employee Pre-Tax Account of the borrowing 
Participant, and (b) no withdrawal pursuant to any of the withdrawal 
provisions of this Plan may be made by a Participant to whom a loan 
is outstanding from the Trust unless the Committee is satisfied that 
such loan will remain nontaxable and fully secured by the withdrawing 
Participant's Vested Interest under the Plan following such 
withdrawal.

                             ARTICLE XVI

               HOURS OF SERVICE AND LEAVES OF ABSENCE

    Section 16.1. Hour of Service Defined. "Hour of Service" means 
each hour for which an Employee is:

     (a) paid, or entitled to payment, for the performance of duties,

     (b) awarded back pay or for which back pay has been agreed to, 
irrespective of mitigation of damages; provided, however, that the 
same Hour of Service shall not be credited both under Subparagraph 
16.1(a) or Subparagraph 16.1(c) as the case may be, and under this 
Subparagraph 16.1(b), and

     (c)  paid, or entitled to payment, on account of a period of 
time during which no duties are performed (irrespective of whether 
the employment relationship has terminated) due to vacation, holiday, 
illness, incapacity (including disability), layoff, jury duty, 
military duty or leave of absence (except as may otherwise be 
provided at Section 16.4 with respect to maternity or paternity 
leaves); provided, however, that

             (i)  An hour for which an Employee is directly or 
indirectly paid, or entitled to payment, on account of a period 
during which no duties are performed shall not be credited to him if 
such payment is made or due under a plan maintained solely for the 
purpose of complying with applicable workmen's compensation, or 
unemployment compensation or disability insurance laws; and

             (ii) Hours of Service shall not be credited for a payment 
which solely reimburses an Employee for medical or medically related 
expenses incurred by him.

    For purposes of this Subsection 16.1(c), a payment shall be 
deemed to be made or due from the Employer regardless of whether such 
payment is made by or due from the Employer directly, or is made or 
due indirectly through a trust fund, or insurer, to which the 
Employer contributes or pays premiums. A payment shall also be deemed 
made or due from the Employer whether it is made or due to the trust 
fund, insurer or other entity for the benefit of particular employees 
or for the benefit of a group of employees in the aggregate.




FINA CAPITAL ACCUMULATION PLAN - 48
<PAGE>   53
    Section 16.2. Determination of Hours of Service for Reasons Other 
Than the Performance of Duties. In the case of a payment which is 
made or due on account of a period during which an Employee performs 
no duties, and which results in the crediting of Hours of Service 
under Subsection 16.1(c), or in the case of an award or agreement for 
back pay, to the extent that such award or agreement is made with 
respect to a period described in Subsection 16.1(b), the number of 
Hours of Service to be credited shall be determined in accordance 
with the provisions of Department of Labor Regulation Section 
2530.200b-2(b).

    Section 16.3. Crediting of Hours of Service to Computation 
Periods.

    (a) Except as provided in Subsection 16.3(d), Hours of Service 
described in Subsection 16.1(a) shall be credited to the Computation 
Period in which the duties are performed.

    (b) Except as provided in Subsection 16.3(d), Hours of Service 
described in Subsection 16.1(b) shall be credited to the Computation

          (ii) Hours of Service credited to an Employee by reason of a 
payment which is not calculated on the basis of units of time shall 
be credited to the Computation Period in which the period during 
which no duties are performed occurs.

in connection with a period of no more than 31 days which extends 
beyond one Computation Period, all such Hours of Service shall be

FINA CAPITAL ACCUMULATION PLAN - 49
<PAGE>   54
by such Employee, or (iv) the care of a child for a period beginning 
immediately following such birth or placement, such Employee shall be 
deemed to be credited with the number of Hours of Service he or she 
normally (but for such absence) would have been credited with during 
the applicable Computation Period in which such absence began, up to 
but not exceeding 501 Hours of Service, provided further, however, 
that if such Employee does not need such credit in such Computation 
Period in order to prevent a One Year Break in Service in the Plan 
Year in which the maternity or paternity leave commenced, such credit 
shall be given in the next subsequent Plan Year.  In the event the 
normal Hours of Service the Employee would have been credited with 
are not determinable, the Employee will be credited with eight (8) 
Hours of Service for each normal working day during such maternity or 
paternity leave.

      As a condition of crediting Hours of Service under this 
Section, the Committee may require (applied in a uniform and 
nondiscriminatory manner) that the Employee provide on a timely 
basis, suitable information (which may include a doctor's statement) 
establishing that the absence is for an allowable period and reason; 
unless such information is already accessible to the Committee 
without the Employee's submission of same.

of the total combined voting power of all stock of the Employer (if

                             FINA RESTORATION PLAN


    1.   Purpose. The purpose of the Fina Restoration Plan is to provide
additional benefits for certain highly compensated employees who participate in
the Fina Capital Accumulation Plan and the Fina Pension Plan. The Plan amends
and completely restates the Excess Benefit Plan of American Petrofina,
Incorporated and Certain Subsidiaries adopted by the Company effective January
1, 1977.

    2.   Definitions. The following definitions are used throughout the Plan.

         (a) "Board of Directors" means the Board of Directors of the Company.

         (b) "CAP" means the Fina Capital Accumulation Plan, as amended from
time to time, which is a defined contribution plan established by the Company
that is intended to qualify under Section 401(a) of the Code and to satisfy the
requirements of a qualified cash or deferred arrangement under Section 401(k)
of the Code.

         (c) "Code" means the Internal Revenue Code of 1986, as amended and in
effect from time to time.

         (d) "Committee" means the Retirement Committee of the Company.

         (e) "Company" means Fina, Inc., a Delaware corporation.

         (f) "ERISA" means the Employee Retirement Income Security Act of 1974,
as amended.

         (g) "Participant" means an employee who is eligible to receive
benefits under the Plan. The term "Participant" will include the beneficiary of
a deceased Participant, unless the context clearly requires a different
interpretation.

         (h) "Participating Employer" means the Company and any subsidiary or
other affiliate of the Company that participates in CAP or the Pension Plan.

         (i) "Pension Plan" means the Fina Pension Plan, as amended from time

Company and is intended to qualify under Section 401(a) of the Code.

         (k) "Plan Year" means the calendar year.

         (l) "Restoration CAP Benefit" means the benefit described in Section

         (m) "Restoration Pension Benefit" means the benefit described in
Section 4(b).

         (n) "Restoration Plan Account" means the account established for a
Participant under Section 5.

    3.   Eligibility. An employee of a Participating Employer will be a
Participant if he has elected to participate in CAP and is subject to the
limitation on compensation under Code Section 401(a)(17) or he is a participant
in the Pension Plan and is subject to the limitation on compensation under Code
Section 401(a)(17) or the limitation on benefits under Code Section 415.

    4.   Restoration Benefits.

         (a) Restoration CAP Benefit. A Participant's Restoration CAP Benefit
for any Plan Year will be the difference, if any, between (i) and (ii) below,
where:

             (i) is the amount of employer matching contributions and
    forfeitures that would be contributed and/or allocated to the Participant's
    accounts under CAP on the basis of the Participant's rate of before-tax or
    after-tax contributions to CAP determined without regard to the maximum
    dollar limitation on compensation under Code Section 401(a)(17) but taking
    into account all other applicable limitations on contributions and
    allocations under CAP; and

             (ii) is the amount of employer matching contributions and
    forfeitures actually allocated to the Participant's CAP accounts for the
    Plan Year and not forfeited or distributed to the Participant pursuant to
    Code Section 401(m)(6) or 4979(f).

         (b) Restoration Pension Benefit. A Participant's Restoration Pension
Benefit will be an annual benefit equal to the difference, if any, between (i)
and (ii) below, where:

             (i) is the annual benefit that would be payable to the Participant
    under the Pension Plan beginning on his benefit commencement date if such
    benefit were determined





                                      -2-
<PAGE>   4
    without regard to the maximum dollar limitation on compensation under Code
    Section 401(a)(17) or the maximum benefit limitation under Code Section 415
    but taking into account all other applicable benefit limitations under the
    Pension Plan; and

             (ii) is the annual benefit payable to the Participant under the
    Pension Plan beginning on his benefit commencement date after applying the
    limitations of Code Sections 401(a)(17) and 415 and all other applicable
    benefit limitations under the Pension Plan.

    5.   Restoration Plan Accounts. The amount of a Participant's Restoration
CAP Benefit for any Plan Year will be credited as of a date or dates selected
by the Committee, but not later than the last day of the Plan Year, to an
account established for the Participant under the Plan. Amounts credited to the
Participant's Restoration Plan Account will be deemed to be invested on the
date on which the credit is made in whole and fractional shares of Class A
common stock of the Company.

    6.   Vesting. Subject to the rights of general creditors as set forth in
Section 10 and the right of the Company to discontinue the Plan as provided in
Section 13, a Participant will be vested in his Restoration CAP Benefit to the
same extent that he has a vested interest in his employer-provided benefit
under CAP and will be vested in his Restoration Pension Benefit to the same
extent that he has a vested interest in his employer-provided benefit under the
Pension Plan, unless the Participant's employment with the Company or any
subsidiary of the Company is terminated for Cause (as hereinafter defined). If
a Participant is terminated for Cause, the Participant's Restoration CAP
Benefit and his Restoration Pension Benefit will be forfeited and the
Participant will not be entitled to any benefit under the Plan.  For purposes
of the Plan, "Cause" means any intentional act of fraud, embezzlement, or theft
committed by a Participant in the course of the Participant's employment by a
Participating Employer or any other intentional misconduct engaged in by the
Participant which is materially injurious to the business, reputation or
property of a Participating Employer.

    7.   Commencement of Benefits.

         (a) Restoration CAP Benefit. A Participant's vested interest in his
Restoration CAP Benefit will be paid as soon as practicable following his
termination of employment for any reason (including death) with all
Participating Employers.

         (b) Restoration Pension Benefit. Payment of a Participant's vested
interest in his Restoration Pension benefit will begin on the date that the
Participant begins to receive





                                      -3-
<PAGE>   5
payment of his pension benefit under the Pension Plan. If payment of the
Restoration Pension Benefit begins before the Participant's normal retirement
age under the Pension Plan, the amount of his Restoration Pension Benefit will
be determined by applying the same reduction factors that are applicable to his
Pension Plan benefit.

    8.   Form of Benefits.

         (a) Restoration CAP Benefit. A Participant's vested Restoration CAP
Benefit will be paid in cash, in a single lump sum distribution. The amount of
his Restoration CAP Benefit will be determined by valuing the whole and
fractional shares of Class A common stock of the Company credited to his
Restoration Plan Account as of the valuation date under CAP immediately
preceding the date of distribution.

         (b) Restoration Pension Benefit. A Participant's Restoration Pension
Benefit will be paid in the same form as the normal form of the Participant's
pension benefit under the Pension Plan; provided, however, that if the
Participant elects to receive his Pension Plan benefit in an optional form, the
Restoration plan Benefit will be paid in the same optional form and will be
subject to the same reduction factors used under the Pension Plan to convert
the Participant's normal form of pension benefit to the optional form.
Notwithstanding the foregoing, the Participant may elect to receive his
Restoration Pension Benefit in an actuarially equivalent lump sum payment,
provided he makes such election at least six months prior to his benefit
commencement date or at such other time as the Committee determines is
appropriate. The value of such lump sum payment will be determined by using a
discount rate equal to the published interest rates that would be used (as of
the first day of the calendar quarter in which the distribution is made) by the
Pension Benefit Guaranty Corporation for purposes of determining the present
value of a lump sum distribution on termination of a defined benefit pension
plan and such other actuarial factors as are used in determining actuarial
equivalence under the Pension Plan.

    9.   Death Benefits.

         (a) Restoration CAP Benefit. If a Participant who is entitled to
receive a Restoration CAP Benefit dies before receiving such benefit, the
amount of the Restoration Plan benefit will be paid to the person or persons
(including his estate) who are recognized under CAP as the beneficiary of the
Participant's CAP benefit.

         (b) Restoration Pension Benefit. Upon the death of a Participant who
is receiving a Restoration Pension Benefit, the





                                      -4-
<PAGE>   6
Restoration Pension Benefit will continue to be paid (if at all) in accordance
with the form of payment elected by the Participant under Section 8(b). If a
Participant who is entitled to receive a Restoration Pension Benefit dies
before payment of such benefit begins, the Participant's Restoration Pension
Benefit will be paid as a death benefit in the same manner, to the same extent
and to the same beneficiary as the Participant's pension benefit is continued
(if at all) under the Pension Plan.

    10.  Funding of Benefits. (a) The Plan will be unfunded. All benefits
payable to a Participant under the Plan will be paid from the general assets of
the Participating Employers that employed the Participant, and nothing
contained in the Plan will require the Participating Employers to set aside or
hold in trust any funds for the benefit of a Participant, who will have the
status of a general unsecured creditor with respect to the obligation of the
Participating Employers to make payments under the Plan. Any funds of the
Participating Employers available to pay benefits under the Plan will be
subject to the claims of general creditors of the Participating Employers and
may be used for any purpose by the Participating Employers.

         (b) If the benefits payable under the Plan to a Participant is
attributable to periods of employment with more than one Participating
Employer, the Committee may allocate liability for the payment of the benefit
among the Participating Employers in any manner the Committee, in its sole
discretion, determines to be appropriate.

         (c) Notwithstanding the provisions of Section 10(a), the Company may,
at the direction, and in the absolute discretion, of the Committee, transfer to
the trustee of one or more trusts established for the benefit of one or more
Participants assets from which all or a portion of the benefits provided under
the Plan will be satisfied, provided that such assets held in trust will at all
times be subject to the claims of general unsecured creditors of the
Participating Employers, and no Participant will at any time have a prior claim
to such assets. To the extent that benefits under the Plan are paid from any
such trust, the Participating Employers will be relieved of all liability for
such benefits.

    11.  Administration of the Plan. (a) The Committee will administer the Plan
and will have the full authority and discretion to accomplish that purpose,
including without limitation, the authority and discretion to (i) interpret the
Plan and correct any defect, supply any omission or reconcile any inconsistency
or ambiguity in the Plan in the manner and to the extent that the Committee
deems desirable to carry the purpose of the Plan, (ii) resolve all questions
relating to the eligibility of employees to become Participants, (iii)
determine





                                      -5-
<PAGE>   7
the amount of benefits payable to Participants and authorize and direct the
Company with respect to the payment of benefits under the Plan, (iv) make all
other determinations and resolve all questions of fact necessary or advisable
for the administration of the Plan, and (v) make, amend and rescind such rules
as it deems necessary for the proper administration of the Plan. The Committee
will keep a written record of its action and proceedings regarding the Plan and
all dates, records and documents relating to its administration of the Plan.

         (b) Any action taken or determination made by the Committee will,
except as otherwise provided in Section 12 below, be conclusive on all parties.
No member of the Committee will vote on any matter relating specifically to
such member. In the event that a majority of the members of the Committee will
be specifically affected by any action proposed to be taken (as opposed to
being affected in the same manner as each other Participant in the Plan), such
action will be taken by the Board of Directors.

    12.  Claims Procedure. (a) If a Participant does not receive the benefits
which he believes he is entitled to receive under the Plan, he may file a claim
for benefits with the Committee. All claims will be made in writing and will be
signed by the claimant. If the claimant does not furnish sufficient information
to determine the validity of the claim, the Committee will indicate to the
claimant any additional information which is required.

         (b) Each claim will be approved or disapproved by the Committee within
90 days following the receipt of the information necessary to process the
claim. In the event the Committee denies a claim for benefits in whole or in
part, the Committee will notify the claimant in writing of the denial of the
claim. Such notice by the Committee will also set forth, in a manner calculated
to be understood by the claimant, the specific reason for such denial, the
specific Plan provisions on which the denial is based, a description of any
additional material or information necessary to perfect the claim with an
explanation of why such material or information is necessary, and an
explanation of the Plan's claim review procedure as set forth below. If no
action is taken by the Committee on a claim within 90 days, the claim will be
deemed to be denied for purposes of the review procedure.

         (c) A claimant may appeal a denial of his claim by requesting a review
of the decision by the Committee or a person designated by the Committee, which
person will be a named fiduciary under Section 402(a)(2) of ERISA for purposes
of this Section. An appeal must be submitted in writing within six months after
the denial and must (i) request a review of the claim for benefits under the
Plan, (ii) set forth all of the





                                      -6-
<PAGE>   8
grounds upon which the claimant's request for review is based and any facts in
support thereof, and (iii) set forth any issues or comments which the claimant
deems pertinent to the appeal. The Committee or the named fiduciary designated
by the Committee will make a full and fair review of each appeal and any
written materials submitted in connection with the appeal. The Committee or the
named fiduciary designated by the Committee will act upon each appeal within 60
days after receipt thereof unless special circumstances require an extension of
the time for processing, in which case a decision will be rendered as soon as
possible but not later than 120 days after the appeal is received. The claimant
will be given the opportunity to review pertinent documents or materials upon
submission of a written request to the Committee or named fiduciary, provided
the Committee or named fiduciary finds the requested documents or materials are
pertinent to the appeal. On the basis of its review, the Committee or named
fiduciary will make an independent determination of the claimant's eligibility
for benefits under the Plan. The decision of the Committee or named fiduciary
on any claim for benefits will be final and conclusive upon all parties
thereto. In the event the Committee or named fiduciary denies an appeal in
whole or in part, it will give written notice of the decision to the claimant,
which notice will set forth in a manner calculated to be understood by the
claimant the specific reasons for such denial and which will make specific
reference to the pertinent Plan provisions on which the decision was based.

    13.  Miscellaneous. (a) Nothing in the Plan will confer upon a Participant
the right to continue in the employ of the Participating Employers or will
limit or restrict the right of the Participating Employers to terminate the
employment of a Participant at any time with or without cause.

         (b) Except as otherwise provided in the Plan, no right or benefit
under the Plan will be subject to anticipation, alienation, sale, assignment,
pledge, encumbrance or charge, and any attempt to anticipate, alienate, sell,
assign, pledge, encumber or charge such right or benefit will be void. No such
right or benefit will in any manner be liable for or subject to the debts,
liabilities or torts of a Participant.

         (c) The Plan may be amended at any time by the Committee provided such
amendment does not have the effect of increasing, directly or indirectly, the
benefit of any Participant. The Plan may also be amended or terminated by the
Board of Directors at any time. No action taken by the Committee or by the
Board of Directors to amend or terminate the Plan will have the effect of
decreasing a Participant's Plan benefit as of the date of such action.





                                      -7-
<PAGE>   9
         (d) The Plan is intended to provide benefits for "management or highly
compensated" employees within the meaning of Sections 201, 301 and 401 of
ERISA, and therefore to be exempt from the provisions of Parts 2, 3 and 4 of
Title I of ERISA. Accordingly, the Plan will terminate and no further benefits
will accrue hereunder in the event it is determined by a court of competent
jurisdiction or by an opinion of counsel that the Plan constitutes an employee
pension benefit plan within the meaning of Section 3(2) of ERISA, which is not
so exempt. In addition, in the absolute discretion of the Committee, the
benefit of each Participant accrued under the Plan on the date of termination
will be paid immediately to such Participant in a single lump sum cash payment.

         (e) If any provision in the Plan is held by a court of competent
jurisdiction to be invalid, void or unenforceable, the remaining provisions
will nevertheless continue in full force and effect without being impaired or
invalidated in any way.

         (f) THE PLAN WILL BE CONSTRUED AND GOVERNED IN ALL RESPECTS IN
ACCORDANCE WITH APPLICABLE FEDERAL LAW AND, TO THE EXTENT NOT PREEMPTED BY SUCH
FEDERAL LAW, IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS.

to be held on April 16, 1997. Discretionary authority to vote unmarked Forms of

given by a security holder may be revoked at any time before it is exercised by
giving written notice of revocation to the Secretary. Copies of this statement

     Article FOURTH of the Certificate of Incorporation provides that on any
vote for the election of directors the holders of record of the Class B Common
Stock shall be entitled, voting separately as a class, to elect the smallest
number comprising more than half of the directors to be elected, and the
remaining directors shall be elected by the holders of record of the Class A
Common Stock, voting separately as a class. In accordance with that provision of
Article FOURTH, at the Annual Meeting the holders of record of the Class B
Common Stock will be entitled to elect five directors and the holders of record
of the Class A Common Stock will be entitled to elect four directors.

     other companies which are to be used in the payment calculation have not
     been published. Any such payments are subject to adjustment based upon the
     recommendation of the Compensation Committee. Payments pertaining to fiscal
     1995 were made in May 1996 and are reported in this column.
 
 (2) No options were awarded during the three-year period.

     restoration portion of the Restoration Plan is set forth herein in the
     retirement table.

     Restoration Plan, reimbursement of $275 tax preparation fee, life insurance
     over $50,000 of $2,129 and the Company's $9,000 matching contribution to

     $9,000 matching contribution to the 401(k) plan. The value of the pension
     restoration portion of the Restoration Plan is set forth herein in the

 (8) Gain on a nonqualified stock option of FINA, Inc. Class A Common Stock
     calculated as the spread between the option price and market price.
 
     Amounts are not included for Pension Plan (described herein) contributions
per employee or officers as a group since such contributions cannot be
separately and individually calculated and no contribution was due by the
Company to the Pension Plan for 1996. Compensation used to determine benefits
under the Pension Plan for employees is a formula based on average total
compensation for the highest three consecutive years of the last ten years of
employment prior to retirement and the highest five consecutive years of the
last ten years as to bonus. Payments made under the incentive program will not
be includable in pension calculations.
 
     An agreement providing supplemental retirement benefits between the Company
and Ron W. Haddock provided that upon retirement at age 55 or later, his
retirement benefit will equal 1.6% of base salary and bonuses over any
thirty-six consecutive month period out of the ten-year period preceding
retirement during which such earnings are the highest multiplied by the number
of completed years of service to the industry from June 11, 1963 to his date of
retirement from the Company. The agreement was amended in fiscal 1993 to vest
these benefits immediately. This determined benefit will then be reduced by a
portion of social security benefits, annuities payable by a previous employer,
benefits from the Company's Pension Plan and retirement benefits from the
Company's Restoration Plan. Amounts payable hereunder are currently
undeterminable. The fiscal 1996 incentive payment will be includable in his
pension calculation under the terms of the agreement. Under this arrangement,
the supplemental benefit which would have been owed by the Company in fiscal
1996 was $149,256.
 
     In 1996 the Company provided certain employees with automobiles and club
memberships for use in the Company's business. Currently, no directors and only
one officer, Mr. Daumerie, are furnished automobiles. Records are kept to
conform to the provisions of the Deficit Reduction Act of 1984. Such officers
and employees may, from time to time, make incidental personal use of club
facilities, but the Company does not require such individuals to maintain
records with respect thereto. The Company provided income tax preparation
service by its independent public accountants to Messrs. Meek, Bercy, Godfrey,
Smoak, Lindley, Morris, West and Rupp in 1996 and reimbursed Mr. Haddock for
expenses associated with income tax preparation. The amounts set forth above as
compensation do not reflect personal benefits which may have been derived by
officers and directors. After reasonable inquiry, the Company has concluded that
the amounts involved, if they could be accurately determined, would be less than
$50,000 in the case of each officer or director.
 
COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
     The Compensation Committee is appointed by the Board of Directors in April
of each year. During 1996, there were two members of the Committee. Patricia M.
Wallington, an outside director, was Chairman of the Committee and served in
this capacity since February 1996. The additional member was Francois Cornelis,
an
 
                                       10

executive of PetroFina S.A. and former employee of the Company. There were no
transactions with management or other items required to be disclosed under Item
404 of Regulation S-K with respect to the Committee members.
 
  Compensation Philosophy and Objectives
 
     The Company's total compensation philosophy for executives is to provide a
competitively based program with an overall objective of creating value for the
Company's shareholders. The compensation program is designed and administered to
achieve the following objectives: (a) to maintain a stable, successful
management team motivated to provide good long-term shareholder returns; (b) to
reward executives based on Company performance, as well as individual
performance, with a significant portion of executive compensation "at risk",
particularly for senior executives; and (c) to provide a compensation system
that appropriately balances short-term and long-term considerations.
 
  Compensation Components
 
     For fiscal 1996, the Company's compensation program consisted of: (i) base
salary, (ii) incentive compensation participation as to executive officers,
(iii) matching contributions under the FINA Capital Accumulation Plan, a 401(k)
plan, (the "FINA Plan"), and (iv) accruals under a restoration plan.
 
     Base Salary -- The base salary levels of Executive Officers are reviewed
annually each April to determine whether they are competitive by comparison with
information from a peer group of companies that participate in the "Petroleum
Industry Executive Compensation Comparison" (hereinafter referred to as PIECC)
survey group. The PIECC companies are closely aligned to the asset/revenue size
of the Company and aligned by industry. However, the Standard Industry
Classification code companies used in the performance graph on page 7 include a
broader range in asset/revenue size than the PIECC companies. There are 27 PIECC
companies including: Amerada Hess, Anadarko Petroleum, Diamond Shamrock, Enron
Oil & Gas, Freeport McMoRan Oil & Gas, Kerr McGee, Maxus Energy, Meridian Oil,
Oryx Energy, Placid Oil, Sonat Exploration, Tesoro Petroleum, and Valero Energy.
The Compensation Committee, receives a memorandum from the President and Chief
Executive Officer as to salary recommendations for the Vice Presidents and
Department Heads reporting to the Chief Executive Officer. This recommendation
has been previously reviewed and approved by the majority security holder. After
action by the Compensation Committee, the salaries and incentive compensation
payments, if any, are subject to approval by the Board of Directors. There was
no modification or rejection in any material way by the Board of Directors of
any decision of the Compensation Committee.
 
     An executive's base salary is heavily weighted by individual performance
and level and scope of responsibility. Executive Officers of the Company
received increases in base salary in fiscal 1996 that ranged from 2.5% to 19.2%
compared with a range of 6% to 15% in 1995. The financial performance of the
Company improved over the previous year. Base salaries for the Company's
Executive Officers, including the named Executive Officers, are generally at or
below the average of the surveyed data.
 
     Deferred Compensation -- In fiscal 1996, FINA had no executive deferred
compensation plan other than (i) the FINA Plan, a 401(k) qualified plan provided
to all eligible employees, as defined in the plan document; (ii) the Pension
Plan, a defined benefit plan more fully described herein; and (iii) a
Restoration Plan which restores Pension Plan and FINA Plan benefits to
executives and employees reaching the maximum participation levels permitted by
law. The FINA Plan is a broad-based pre-tax savings plan which qualifies under
401(k) of the Internal Revenue Code permitting eligible employees, not just
executives, to
 
                                       11
<PAGE>   14
 
defer a portion of their compensation and encourage savings to provide
additional financial security for the future.
 
  CEO Compensation
 
     Mr. Ron W. Haddock has been President and Chief Executive Officer since
1989, and the offices of Chief Executive Officer and President have been
combined throughout that time. Only one salary is paid for the combined
positions. Mr. Haddock's compensation package takes into account the
relationship of the Company to PetroFina S.A. Annually, Mr. Haddock's salary is
reviewed in light of the Company's financial results in addition to utilizing
the PIECC survey used for other executives. Mr. Haddock received a 12.4%
increase in 1996 compared to a 7.4% increase in 1995. No bonus has yet occurred
for fiscal 1996 and he is not entitled to any long-term incentive payment for
the period other than contributions and accruals under the FINA Plan and the
Restoration Plan described herein. Mr. Haddock received a cash bonus of $225,000
in 1996 which was a function of the size of the Company's incentive compensation
pool, but the Compensation Committee also gave subjective consideration to Mr.
Haddock's experience, level and scope of responsibilities, and his overall
contribution to the success of the Company. Recognizing the Company's financial
performance in 1996, it is expected that Mr. Haddock will be awarded an
incentive bonus which will be paid at the same time as the distributions to
other executive officers pursuant to the Company's incentive compensation
program discussed below. The Compensation Committee reserves the right to
determine the final payment recommendation for Mr. Haddock.
 
  Options and Incentive Payment Program
 
     The most recent stock option plan of the Company expired by its terms in
1989. Options at $70.50 were awarded to Executive Officers and employees on a
discretionary basis prior to expiration. The price of the last grant was $70.50.
The price and number of shares were adjusted to $35.25 per share to reflect a
2-for-1 stock split in May 1995. At the date of this report an approximate $15
per share gain has occurred, as adjusted for the stock split.
 
     An incentive compensation program covering all exempt employees, including
executive officers, will provide bonuses based on a formula which includes the
overall financial performance of the Company during 1996, the relative
performance of the Company in comparison to the performance of ten other
companies, the financial performance of the separate lines of business, the
relative performance to ten other companies in the same line-of-business and an
individual performance assessment. Because relative performance of the Company
and each line of business can not be measured until other comparable companies
have announced earnings, the payment amount is incalculable.
 
     To calculate the incentive payments, an executive officer's individual
performance assessment and the competitive total cash compensation target for
his individual position must be established. The resulting dollar amount for an
incentive target is then determined. That dollar amount is then multiplied by a
factor which is weighted 75% on overall corporate performance and 25% on
line-of-business performance. Overall corporate performance will be based on (i)
return on capital employed compared to ten companies: Amerada Hess Corp.,
Ashland Oil Inc., Coastal Corp., Kerr McGee Corp., Murphy Oil Corp., Occidental
Petroleum Corp., Phillips Petroleum Co., Sun Co Inc., Unocal Corp. and
USX-Marathon and; (ii) corporate financial performance above an annually
established minimum return on capital employed. The line-of-business performance
is based on (i) a target tied to that line-of-business' return on capital
employed and cost of capital, and; (ii) that line-of-business' return on assets
compared to ten companies in similar lines of business. A dividend paid-out
factor is used to cap the resulting pool of funds for all incentive payments.
While the Compensation Committee reserves the right to determine the final
incentive payment for each executive
 
                                       12
<PAGE>   15
 
officer, the amount determined under the incentive compensation program will be
a key factor considered by the Compensation Committee when recommending final
payments.
 
  Summary
 
     The Compensation Committee believes that the combination of base salary
paid in 1996 and incentive awards to be paid for 1996 based upon individual and
corporate performance provides a program which attracts and retains key
executives. Incentive awards to be paid for 1996 are directly related to the
financial performance of the Company; i.e., net earnings and performance
rankings to other companies. The actual performance of the Company for fiscal
1996 was $153 million. Earnings per common share were $4.91. The performance of
the Company for fiscal 1995 was a net of $142 million before the effect of an
accounting change and earnings per common share were $4.57 before the effect of
an accounting change.
 
     This Report has been submitted by the Compensation Committee: Francois
Cornelis and Patricia Wallington.
 
  Other Benefit Related Matters
 
     Inapplicability of the $1 Million Deduction Limit. Section 162(m) of the
Internal Revenue Code generally limits the corporate deduction for compensation
paid to Executive Officers to $1 million annually, unless certain requirements
are met. No modification of compensation programs is necessary as no Executive
Officer's compensation approaches $1 million annually.
 
     Transactions with Management and Others. In 1996, there were no
transactions with management or others which are required to be disclosed.
 
     Although the Company has joint venture interests with the majority security
holder and affiliates of PetroFina S.A., only administrative officers are common
to both companies; i.e., the Chief Financial Officer, General Counsel and
Secretary. A description of the joint ventures is under the caption
"Transactions with Security Holders" herein.
 
     Compensation Committee Interlocks and Insider Participation. Francois
Cornelis is a member of the Compensation Committee. He is an executive of an
affiliate, PetroFina S.A., currently serving as Chief Executive Officer and
Vice-Chairman.
 
     Pension Plan. The FINA Pension Plan ("Pension Plan") covers employees of
FINA, Inc. and certain subsidiaries. There were no amendments to the Pension
Plan during 1996.
 
     An eligible employee begins to participate in the Pension Plan on the first
day of the month coincident with or next following completion of twelve
consecutive months of employment during which at least 1,000 hours of service
are credited to such employee. Pursuant to the Tax Reform Act of 1986, the
Company has elected to fully vest participants after five years of service. The
pension formula is offset by up to 50% of an employee's social security primary
insurance amount payable at age 65.
 
     A participant reaches normal retirement age upon attainment of his or her
65th birthday. Married participants normally elect a joint and survivor annuity
as the method of receipt for benefits. Unmarried participants and those with
spousal consent may elect a benefit payable for their lifetime only or a reduced
benefit may be shared with an eligible beneficiary.

 * The maximum benefit limitation established by IRC Section 415(b) is $120,000.
   Benefits exceeding this limitation would be paid through the Company's
   Restoration Plan which mirrors the Pension Plan in operation and
   participation. The Restoration (formerly the Excess Plan) has paid
   supplemental benefits only to executive officers, but was implemented to
   benefit all highly compensated employees whose pension benefit exceeds the
   IRC 415(b) limits.
 
** The covered compensation limit established by IRC Section 401(a)(17) is
   $160,000. Pension benefits that are reduced due to this limitation would also
   be paid through the Company's Restoration Plan. The Restoration Plan has paid
   supplemental benefits to executive officers and one other employee and was
   implemented to benefit all employees whose compensation exceeds the
   401(a)(17) limits.
 
     The remuneration covered by the Pension Plan is composed of all salaries
and bonuses through 1995.
 
     Messrs. Haddock, Jack, Smoak, Couch and Godfrey are vested under the
Pension Plan with service credits of 10.5, 10.8, 12.0, 19.9, and 14.3 years,
respectively.

     Fina Restoration Plan. Effective January 1, 1994, the Company adopted a
plan designed to supplement those persons' pension and 401(k) plan benefits
whose compensation exceeds the 401(a) limits. The plan was named the Fina
Restoration Plan and effectively restores pension and 401(k) plan benefits to
persons making $160,000 or more which otherwise would have been lost due to pay
cap tax limits imposed by the Omnibus Budget Reconciliation Act. This plan is
being implemented to benefit those whose compensation exceeds the 401(a)(17)
limits and the 415(b) limits.
 
     The participant's benefit under this plan as to 401(k) compensatory related
sums will be paid in a single, lump-sum distribution upon death, retirement or
termination of employment for any reason. The pension related benefit can be
paid as a lump sum under the same circumstances or can be annuitized over the
lifetime of the person. The pension related benefit is subject to all conditions
of the Fina Pension Plan.
 
     The amount of employer matching contributions and forfeitures that would
have been attributed to the participant will be identified to the participant.
Annual crediting will occur to a bookkeeping account as if shares of the
Company's Class A Common Stock had been purchased with the dollar amount,
although no actual shares of the Company's stock will be purchased or traded.
 
     In 1996, $191,895 was credited to officers' and employees' accounts
compared to $123,629 in 1995.
 
     Employee Thrift Plan. The FINA Capital Accumulation Plan ("FINA Plan"), a
401(k) plan, was renamed in 1991. The Board of Directors adopted the FINA Plan
as described below in April 1991. The FINA Plan has been substantially in the
same form since June 1988 and is described in the following text. In January
1993 the existing plan was amended to recognize service for purposes of
participant vesting based upon length of employment as opposed to length of
participation in the Plan.
 
     In June 1988, the Board of Directors approved an amendment to the FINA
Plan, then known as the Thrift and Employee Stock Ownership Plan of American
Petrofina, Incorporated, which provided that: (1) the plan, as amended, was
renamed the Thrift Plan of American Petrofina, Incorporated, (2) the
participants' interests in the PAYSOP provision was spun off to a separate new
plan named American Petrofina, Incorporated PAYSOP and Trust (the PAYSOP), and
(3) the PAYSOP was then terminated effective July 31, 1988, with the
participants' interests distributed in cash, stock, or transferred into the FINA
Plan. No amendments to the FINA Plan were made in 1989 or in 1990.
 
     Effective January 1, 1984, the former Thrift Plan for Employees of American
Petrofina, Incorporated and the former Employee Stock Ownership Plan of American
Petrofina, Incorporated were combined and renamed "The Thrift and Employee Stock
Ownership Plan of American Petrofina, Incorporated." A 401(k) feature was added
to the FINA Plan allowing employees to invest up to 10% of their basic income on
a tax-deferred basis and allowing employees to purchase PetroFina S.A. common
stock. A Registration Statement Form S-8, was filed to effect the FINA Plan
which was approved by the Board of Directors on December 15, 1983.
 
     The FINA Plan allows participants to contribute up to 5% of basic earnings
on an after-tax basis, up to 10% on a pre-tax basis, or a combination of pre-tax
and after-tax contributions not exceeding 10%. The Company will contribute an
equal amount up to the first 6% pre-tax of the participant's base income.
Company contributions are invested in the Company's Class A Common Stock and/or
PetroFina S.A. Common Stock at the election of the employee. The employee's
contribution is invested at his or her direction in either of these stocks or in
The Northern Trust Collective Short-Term Investment Fund, Wells Fargo U.S. Debt
Index, American Balanced Fund, Wells Fargo Equity Index Fund or a global fund
named New Perspective Fund.

     Stock Options. The employee Non-Qualified Stock Option Plan -- 1979 (the
"1979 Plan") was adopted by the Board of Directors of the Company on August 7,
1979, ratified by the Company's security holders on April 16, 1980, and expired
by its terms in August 1989. Under the 1979 Plan, in 1979, 1981, 1983, 1984 and
1988, 134,000 shares, 16,900 shares, 102,950 shares, 1,800 shares, and 42,550
shares, respectively, were granted to officers and employees of the Company and
its subsidiaries. Of the 1979 and 1981 grants, 43,548 shares and 4,800 shares,
respectively, were converted to Incentive Stock Options. The 1983 and 1984
grants were incentive stock option grants exclusively. The 1988 options granted
were entirely non-qualified in composition. In addition to the options in the
years noted above, an option was exclusively granted in 1986 to Ron W. Haddock
for 5,000 shares at $47.125 per share which was fully exercised in 1992. All
shares subject to the 1979 Plan are shares of the Company's Class A Common
Stock.
 
     The 1979 Plan was amended in April 1984 at the Annual Meeting of Security
Holders to (i) allow stock to be traded for its cash equivalent for option
stock, (ii) allow the Board of Directors to issue Incentive Stock Options, and
(iii) impose a two-year holding period on stock issued pursuant to an Incentive
Stock Option.
 
     No grants were made in 1996 as the 1979 Plan has expired, and no grant
table is presented.

CEO and the other four most highly compensated executives follows in tabulation

     Phantom Share Plan. In 1979 the Board of Directors of the Company adopted a
Phantom Share Plan under which senior management of the Company and designated
subsidiaries ("Participants") may be credited with phantom shares ("Rights") at
the discretion of a committee of the Board of Directors of the Company. During
1996 there were five Participants. Upon retirement or termination of employment,
or in other specified circumstances, a Participant will be entitled to receive
for each phantom share credited to his account the excess, if any, of (a) the 20
day average market price per share of the Company's Class A Common Stock, plus
dividends and other distributions paid on each share of such Class since such
phantom share was credited to his account over (b) the price assigned to such
phantom share by the Committee under the Phantom Share Plan at the time it was
credited to his account. Such amount will generally be paid in cash over a
five-year period. No grant or amendment has been made to the Phantom Share Plan
since 1980.

     The increase in net value during 1996 of the unvested Rights for all
Participants as a group was $1,210 (excluding basis). The formula used to
calculate the annual increase or decrease in value is based on the change in
annual market value per share, plus dividends per share, multiplied by the
number of phantom share rights which remain unvested. No amounts were paid or
distributed during the last fiscal year to the five persons named in the Summary
Compensation Table.
