                                5,338,513 SHARES

                                  COMMON STOCK
 
                            $.01 PAR VALUE PER SHARE
 
    This Prospectus relates to 5,338,513 shares of common stock (the "Common
Stock") of Freeport-McMoRan Sulphur Inc. ("Freeport Sulphur" or the "Company")
which will be delivered on a pro rata basis to the holders of common stock of
Freeport-McMoRan Inc. ("FTX"), in connection with the proposed merger (the
"Merger") of FTX into IMC Global Inc. ("IGL").
 
    Freeport Sulphur is a newly-formed, wholly-owned subsidiary of
Freeport-McMoRan Resource Partners, Limited Partnership, a Delaware limited
partnership ("FRP"), of which FTX is the administrative managing general partner
and the owner of a 51.6% partnership interest. In connection with the Merger,
FRP has agreed to contribute to Freeport Sulphur the assets and liabilities of
FRP's sulphur business and certain of FRP's oil and gas operations, including
those businesses commonly referred to as the "Main Pass" operations, and IGL has
agreed to transfer its separate interest in the Main Pass operations to FRP,
which FRP will also contribute to Freeport Sulphur. Following those
contributions, Freeport Sulphur will own an 83.3% interest in the Main Pass
operations and will own 100% of the other assets contributed by FRP.
 
    Following the contributions, FRP will distribute all of the shares of Common
Stock to FTX and the other holders of its units of partnership interest in
accordance with their respective partnership interests, such that, following
such distribution and immediately prior to the effective time of the Merger, FTX
will own 5,338,513, or 51.6%, of the shares of Common Stock and FRP's public
unitholders will own in the aggregate 5,008,065, or 48.4%, of the shares of
Common Stock. Upon consummation of the Merger, each FTX stockholder will then
receive a proportionate number of shares of Common Stock received by FTX from
FRP.
 
    Under the terms of an Agreement and Plan of Merger dated August 26, 1997
between FTX and IGL (the "Merger Agreement"), and based on the approximately
25.1 million shares of FTX common stock outstanding as of the date of this
Prospectus, each FTX stockholder would be entitled to receive approximately
0.2123 of a share of Common Stock for each share of FTX common stock held (or
0.1980 of a share of Common Stock if all outstanding options to acquire FTX
common stock were exercised on or before such date). In connection with the
solicitation of the vote of the FTX stockholders and the IGL stockholders on the
Merger Agreement, FTX and IGL have delivered to their respective stockholders a
Joint Proxy Statement/Prospectus (the "Proxy Statement") describing the material
terms of the Merger, to which this Prospectus has been attached as Annex VIII.
 
    All of the shares of Common Stock being delivered hereby are being received
by FTX from FRP and delivered to the FTX stockholders upon consummation and in
consideration of the Merger. No separate consideration will be paid by FTX
stockholders for the shares of Common Stock being delivered hereby. There is
currently no public trading market for the shares of Common Stock. Freeport
Sulphur has applied for listing of the Common Stock on the New York Stock
Exchange upon notice of issuance and expects to receive approval of such listing
prior to the distributions.
 
    RECIPIENTS OF THE COMMON STOCK SHOULD NOTE THE FACTORS DISCUSSED IN "RISK
FACTORS" BEGINNING ON PAGE 10.

<PAGE>
                               PROSPECTUS SUMMARY
 
    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION AND FINANCIAL STATEMENTS, INCLUDING THE NOTES THERETO, APPEARING
ELSEWHERE IN THIS PROSPECTUS. UNLESS OTHERWISE NOTED OR THE CONTEXT REQUIRES
OTHERWISE, REFERENCES HEREIN TO THE HISTORICAL OPERATIONS AND PERFORMANCE OF THE
"COMPANY" OR "FREEPORT SULPHUR" REFER ONLY TO THE OPERATIONS AND PERFORMANCE OF
THE FRP TRANSFERRED BUSINESSES AND NOT OF THE IGL TRANSFERRED BUSINESSES, AND
PROSPECTIVE STATEMENTS ABOUT THE "COMPANY" OR "FREEPORT SULPHUR" REFER TO
FREEPORT SULPHUR AS IF EACH OF THE CONTRIBUTION AND THE DISTRIBUTIONS (AS
DEFINED BELOW) HAD BEEN CONSUMMATED.
 
                        THE MERGER AND THE DISTRIBUTIONS
 
    This Prospectus relates to 5,338,513 shares of Common Stock of the Company
which are to be delivered on a pro rata basis to the holders of common stock,
$.01 par value, of FTX (the "FTX Common Stock") in connection with the proposed
Merger of FTX into IGL (the "FTX Stockholder Distribution"). Under the terms of
the Merger Agreement, each share of FTX Common Stock that is issued and
outstanding at the effective time of the Merger (the "Effective Time") will be
converted into the right to receive, (i) 0.90 of a share of IGL common stock,
$1.00 par value (the "IGL Common Stock"), (ii) one-third of a warrant to
purchase a share of IGL Common Stock, with each whole warrant representing a
right to purchase one share of IGL Common Stock for $44.50 per share, and (iii)
a proportionate number of shares of Common Stock that will be held by FTX
immediately prior to the Effective Time. Cash will be issued in lieu of
fractional shares and fractional warrants. Based on the approximately 25.1
million shares of FTX Common Stock outstanding as of the date of this
Prospectus, each FTX stockholder would be entitled to receive approximately
0.2123 of a share of Common Stock for each share of FTX Common Stock held at the
Effective Time (or approximately 0.1980 of a share of Common Stock if all
outstanding options to acquire FTX Common Stock were exercised on or before the
Effective Time). If all outstanding options to acquire FTX Common Stock that are
"in the money" as of the date of this Prospectus were exercised, there would be
25.9 million shares of FTX Common Stock outstanding and the exchange ratio would
be 0.2064 of a share of Common Stock for each share of FTX Common Stock.
 
    In connection with the Merger, FRP and the Company have entered into a
Contribution and Distribution Agreement dated August 26, 1997 (the "Distribution
Agreement"), pursuant to which FRP has agreed to contribute to Freeport Sulphur
the assets and liabilities of FRP's sulphur business, and of certain of FRP's
oil and gas operations, including those businesses commonly referred to as the
"Main Pass" operations, located offshore Louisiana in the Gulf of Mexico (the
"FRP Transferred Businesses"). Also in connection with the Merger and under the
terms of a separate contribution agreement, IGL has agreed to transfer to FRP
its separate interest in the Main Pass operations (the "IGL Transferred
Businesses"), which FRP will also contribute to Freeport Sulphur. The
contributions by FRP and IGL of the FRP and IGL Transferred Businesses are
referred to herein as the "Contribution," and the assets, liabilities and
businesses so transferred are referred to collectively herein as the
"Transferred Businesses." Following the Contribution, the Company will own an
83.3% interest in the Main Pass operations (with Homestake Sulphur Company
("Homestake") continuing to own the remaining 16.7%), and will own 100% of the
other assets contributed by FRP pursuant to the Distribution Agreement.
 
   
    Following the Contribution, FRP will distribute all 10,346,578 shares of the
Company's Common Stock to FTX and the other holders of its units of partnership
interest (the "FRP Distribution" and together with the FTX Stockholder
Distribution, the "Distributions") in accordance with their respective
partnership interests, such that, following the FRP Distribution and immediately
prior to the Effective Time, FTX will own 5,338,513, or 51.6%, of the
outstanding shares of Common Stock and FRP's public unitholders will own in the
aggregate 5,008,065, or 48.4%, of the outstanding shares of Common Stock. At the
Effective Time, each FTX stockholder will be entitled to receive a proportionate
number of shares of the Common Stock received by FTX in the FRP Distribution.
The FRP Distribution will not be effected until approval of the Merger by the
stockholders of FTX and IGL has been received and all other
    
 
                                       3
<PAGE>
conditions to the Merger (other than the FRP Distribution) have been satisfied
or waived, and the FTX Stockholder Distribution will not be effected until the
FRP Distribution and the Merger have been consummated.
 
   
    The 10,346,578 shares of Common Stock to be distributed to the FTX
stockholders and to the FRP public unitholders in the Distributions will
constitute all of the outstanding Common Stock immediately following the
Distributions. There is currently no public market for the Common Stock,
although it is expected that a "when-issued" trading market may develop on or
about the Effective Time. Freeport Sulphur has applied for listing of the Common
Stock on the New York Stock Exchange (the "NYSE") upon notice of issuance and
expects to receive approval of such listing prior to the Distributions. See
"Description of Capital Stock."
    
 
                                  THE COMPANY
 
    Freeport Sulphur is a Delaware corporation formed in August 1997 to succeed
to the sulphur and certain oil and gas operations of FRP. Management believes
that Freeport Sulphur is the world's largest producer of mined, or "Frasch,"
sulphur and the largest supplier of elemental sulphur in the United States. The
Company's sulphur operations include the mining, purchase, transportation,
terminaling and marketing of sulphur. Its oil and gas operations consist of the
production and sale of oil and gas from its Main Pass facilities.
 
    The Main Pass sulphur deposit, which was discovered offshore Louisiana in
the Gulf of Mexico in 1988, is the largest known sulphur reserve in North
America. The Company's Main Pass offshore mining complex is the largest
structure of its type in the Gulf of Mexico and one of the largest in the world,
and was designed to produce an average of 5,500 long tons (2,240 lbs.) per day
over its life. The Company began operating the Culberson mine in West Texas in
January 1995 following its acquisition of substantially all of the domestic
sulphur assets of Pennzoil Company ("Pennzoil"). As of December 31, 1996, the
Main Pass and Culberson mines were estimated to contain proved sulphur reserves
totaling 53.1 million long tons net to the Company (or 69.7 million long tons
net to the Company on a pro forma basis after the contribution of the IGL
Transferred Business). In addition to the Culberson mine, the Company also
acquired from Pennzoil sulphur terminals and handling facilities in Galveston,
Texas and Tampa, Florida, land and marine transportation equipment, and sales
and other related commercial contracts and obligations.
 
   
    The Company's principal business is the sale of sulphur and the marketing of
its terminaling and transportation assets for use by recovered sulphur producers
and industrial consumers of sulphur. The phosphate fertilizer industry generally
accounts for approximately 90% of the Company's sulphur sales. The Company's
1996 sulphur sales were approximately 2.9 million long tons representing 25% of
domestic consumption (or 3.4 million long tons representing 30% of domestic
consumption on a pro forma basis after the contribution of the IGL Transferred
Businesses). Sales to IMC-Agrico Company, a joint venture partnership between
IGL and FRP that is a manufacturer of phosphate fertilizers and the largest
purchaser of elemental sulphur in the world, ("IMC-Agrico"), represented
approximately 65% of the Company's sulphur sales (or 71% on a pro forma basis
after the contribution of the IGL Transferred Businesses). Pursuant to a Sulphur
Supply Agreement, the Company has agreed to supply and IMC-Agrico has agreed to
purchase approximately 75% of IMC-Agrico's annual sulphur consumption for as
long as IMC-Agrico has an operational need for sulphur. The price per ton for
all sulphur delivered under the agreement is based upon the weighted average
market price for sulphur delivered by other sources to IMC-Agrico's New Wales
production plant in central Florida, except that the Company is entitled to a
premium with respect to approximately 40% of the sulphur that it delivers under
the agreement. IMC-Agrico also pays a portion of the freight costs associated
with the delivery of sulphur under the agreement. Management believes that the
terms of the Sulphur Supply Agreement are no less favorable to the Company than
those that could have been negotiated with an unaffiliated party.
    
 
                                       4
<PAGE>
   
    The Main Pass site also contains proved oil reserves from which the Company
produces and sells oil for the Main Pass joint venture. Oil production averaged
approximately 10,700 barrels per day (5,200 barrels net to the Company, or 7,400
barrels net to the Company on a pro forma basis after the contribution of the
IGL Transferred Businesses) during the year ended December 31, 1996, and 9,400
barrels per day (4,600 barrels net to the Company, or 6,500 barrels net the
Company on a pro forma basis after the contribution of the IGL Transferred
Businesses) during the nine months ended September 30, 1997. As of December 31,
1996, Main Pass was estimated to contain 12.8 million barrels (5.2 million
barrels net to the Company, or 7.4 million barrels net to the Company on a pro
forma basis after the contribution of the IGL Transferred Businesses) of proved
oil reserves. In 1997, such estimates were reduced to 8.2 million barrels (3.2
million barrels net to the Company, or 4.6 million barrels net to the Company on
a pro forma basis after the contribution of the IGL Transferred Businesses) of
proved oil reserves, which are expected to decline substantially in subsequent
years and to be fully depleted by 2001.
    
 
    The Company's principal executive offices are located at 1615 Poydras
Street, New Orleans, Louisiana 70112, and its telephone number is (504)
582-4000.
 
                   SUMMARY OF FEDERAL INCOME TAX CONSEQUENCES
 
    The following summary of the material United States federal income tax
consequences of the receipt by the FTX stockholders of the Company's Common
Stock in the Merger is based on an opinion of Miller & Chevalier, Chartered, tax
counsel to FTX. This summary is qualified by, and amplified in, the discussion
in the section of this Prospectus entitled "Certain Federal Income Tax
Consequences."
 
    FTX stockholders will receive shares of Common Stock as part of the
consideration in the Merger. Each stockholder will recognize gain, if any, but
not loss, on the Merger to the extent of the fair market value of the shares of
Common Stock (including the amount of cash received in lieu of a fractional
share interest) received in the Merger. IGL will determine the fair market value
of the Common Stock for this purpose, but its determination is not binding on
the Internal Revenue Service (the "IRS"). While not free from doubt due to the
absence of controlling precedent, gain recognized by an FTX stockholder who is
not also an IGL stockholder should constitute capital gain, rather than dividend
income, assuming that the stockholder held the FTX Common Stock with respect to
which the Common Stock is received as a capital asset. FTX stockholders who also
own IGL stock should consult their own tax advisors for special considerations
that may apply in regard to the receipt of Common Stock or cash in lieu of a
fractional share thereof. An individual stockholder's capital gain will be
taxable at a maximum federal income tax rate of 20% or 28%, if the FTX
stockholder held the surrendered shares of FTX Common Stock for more than 18
months or 12 months, respectively, as of the Effective Time.
 
    A "Non-U.S. Holder" (as defined in "Certain Federal Income Tax
Consequences") will not be subject to United States federal income tax on any
gain realized on the receipt of Common Stock in the Merger unless (a) the gain
is derived from sources within the United States and the Non-U.S. Holder is a
nonresident alien individual who is present in the United States for 183 days or
more during the taxable year in which the gain is realized; (b) the Non-U.S.
Holder is subject to tax pursuant to the provisions of U.S. federal tax law
applicable to certain United States expatriates; (c) the gain is effectively
connected with the conduct of a trade or business within the United States; or
(d) the FTX Common Stock is a "United States real property interest" as defined
in section 897(c)(1) of the Code and at any time during the five years prior to
the Merger the Non-U.S. Holder held, directly or constructively, more than 5% of
the FTX Common Stock.
 
    The basis of the Common Stock received by an FTX stockholder will be equal
to its fair market value as of the Effective Time. The stockholders' holding
periods for the Common Stock will begin on the day after the Effective Time.

                      SUMMARY FINANCIAL AND OPERATING DATA
 
    The summary financial data provided below reflect the historical results of
operations and financial position of the FRP Transferred Businesses only and do
not include the IGL Transferred Businesses. The historical financial information
is not necessarily indicative of the financial position and results of
operations that would have been achieved had the Company been operated as an
independent entity during the periods covered or the results that may be
achieved in the future. Historical net income and dividends per share amounts
are not presented because the FRP Transferred Businesses were operated through
divisions of FRP for the periods presented. See "Risk Factors--Limited Relevance
of Historical Financial Information."
 
   
    The summary historical financial information as of December 31, 1996 and
1995 and for each of the years in the three-year period ended December 31, 1996
has been derived from the audited financial statements of the FRP Transferred
Businesses included elsewhere herein and does not include the IGL Transferred

- ------------------------
 
(1) As a partnership, FRP pays no federal or state income taxes and historically
    has not provided for income taxes for the FRP Transferred Businesses. Pro
    forma net income includes an estimated tax provision for the applicable
    periods as if the FRP Transferred Businesses operated as a stand-alone
    taxpaying entity.
 
   
(2) In 1995, the Financial Accounting Standards Board adopted Statement of
    Financial Accounting Standards No. 121 ("SFAS No. 121"), which requires an
    assessment of the carrying value of long-lived assets and a reduction of
    such carrying value to fair value when events or changes in circumstances
    indicate that the carrying amount may not be recoverable. In the third
    quarter of 1997, FRP and FTX determined that the sulphur assets were
    impaired within the meaning of SFAS No. 121 because their book value
    exceeded the estimated undiscounted net cash flow recoverable with respect
    thereto. Accordingly, in the third quarter of 1997, FRP and FTX recorded an
    impairment writedown totaling $425.4 million to reduce these properties to
    their fair value (measured by the difference between the carrying value of
    such assets and the current discounted value of estimated future net cash
    flows).
    
 
   
(3) Includes charges totaling $7.0 million allocated to the FRP Transferred
    Businesses to reflect a compensation charge related to FTX stock
    appreciation rights, which was attributable to the significant rise in the
    price of FTX Common Stock during such period. Pursuant to a management
    services agreement with FTX, these costs were allocated to FRP, and thus to
    the FRP Transferred Businesses, based on payroll costs.
    
 
   
(4) EBITDA represents net income before income taxes plus depreciation and
    amortization expense. EBITDA is not a measure of cash flow, operating
    results or liquidity as determined by generally accepted accounting
    principles. The Company has supplementally disclosed information concerning
    EBITDA because management believes that EBITDA is commonly accepted as
    providing useful information regarding a company's historical ability to
    incur and service debt. Management of the Company believes that factors that
    should be considered by investors in evaluating EBITDA include, but are not
    limited to, trends in EBITDA as compared to cash flow from operations, debt
    service requirements and capital expenditures. EBITDA as defined and
    measured by the Company may not be comparable to similarly titled measures
    of other companies. Further, EBITDA should not be considered in isolation or
    as an alternative to, or more meaningful than, net income or cash flow
    provided by operations as determined in accordance with generally accepted
    accounting principles as an indicator of the Company's profitability or
    liquidity.

<PAGE>
                                  RISK FACTORS
 
COMPETITION
 
    There are two principal sources of elemental sulphur: (i) mined sulphur and
(ii) recovered sulphur produced as a by-product by oil refineries and gas
treatment plants. Recovered sulphur from domestic and foreign sources is a major
and lower cost source of supply for most sulphur customers and is the major
source of competition for the Company. As a by-product of the producer's
refining operations, the principal cost recognized by such producers is the cost
of handling and transportation to customers.
 
    Production of recovered sulphur from high-sulphur gas processing plants and
oil refineries in the United States has increased at an average rate of
approximately 125,000 tons per year for the last three years. Because U.S.
recovered sulphur producers do not have the ability to store large inventories
of sulphur, they must move it to market and, depending on the proximity of their
plants to the principal sulphur market of central Florida, such producers may
enjoy a significant cost advantage over the Company.
 
    Because the supply of U.S. recovered sulphur alone cannot meet total
domestic demand, mined sulphur, along with imported recovered sulphur obtained
principally from Canada and Mexico, are required to supply the balance. Canadian
recovered sulphur producers have facilities for storing excess sulphur
production in solid form, and approximately 90% of the Western Hemisphere's
sulphur inventories currently consist of sulphur recovered from natural gas in
the province of Alberta in western Canada. At certain price levels in the U.S.
sulphur markets, and depending on prices in the foreign markets they supply,
Canadian producers can be expected to increase sulphur sales to U. S. buyers in
competition with the Company.
 
    The principal competitive risk to the Company's ability to mine sulphur
profitably is the potential for decreased domestic demand for sulphur, increased
production from domestic recovered sulphur producers, increases in imported
recovered sulphur and the rate at which stored sulphur, particularly in Canada,
is released into the market. In addition, the current level of Canadian sulphur
inventories limits the potential of the Company to realize significant price
increases for its sulphur. See "Business-- Competition."
 
RELIANCE ON IGL AS CONTINUING CUSTOMER
 
   
    Approximately 65% of the Company's 1996 sulphur sales (71% on a pro forma
basis after the contribution of the IGL Transferred Businesses) were made to
IMC-Agrico, and, subsequent to the Distributions, IMC-Agrico will continue to
account for a substantial percentage of the Company's sulphur sales. Sales of
sulphur to IMC-Agrico are generally made at market prices, with a portion of
such sales receiving additional price consideration. Although the Company has a
long-term supply contract with IMC-Agrico that requires IMC-Agrico to purchase
sulphur from the Company as long as IMC-Agrico's phosphate fertilizer operations
require the use of sulphur, the loss of or a significant decline in its sales of
sulphur to IMC-Agrico could have a material adverse effect on the Company's
business and operating results.
    
 
EFFECT OF PRICES ON SULPHUR MINING OPERATIONS
 
    Although current sulphur prices allow the Company to generate positive cash
flows from its mining operations, any significant decline in the market price of
sulphur for a sustained period would require the Company to consider the
suspension or curtailment of mining operations at either or both of its
operating mines. In such event, it is likely that the Culberson mine would be
closed first, because of the higher transportation costs associated with that
site. Because of the costs associated with closing and re-opening mine sites, as
well as the potential loss of mining or mineral development rights if mining
operations were suspended, the Company could decide to operate its mines for
some period even if they did not generate
 
                                       10
<PAGE>
positive cash flow, and if operations were suspended, it could be difficult and
expensive for the Company to subsequently re-open a mine.
 
SEASONALITY AND VOLATILITY OF SULPHUR MARKETS
 
    Because the principal use of sulphur is in the manufacture of phosphate
fertilizers, the Company's ability to successfully market its sulphur is
materially dependent on prevailing agricultural conditions and the worldwide
demand for fertilizers. Although phosphate fertilizer sales are fairly constant
month-to-month, seasonal increases occur in the domestic market prior to the
fall and spring planting season. Generally, domestic phosphate fertilizer sales
are at reduced levels after the spring planting season, although the decline in
domestic sales generally coincides with the time when major commercial and
governmental buyers in China, India and Pakistan purchase product for mid-year
delivery. Sales are also influenced by current and projected grain inventories
and prices, quantities of fertilizers imported to and exported from North
America, domestic fertilizer consumption and the agricultural policies of
certain foreign governments.
 
    Like other commodities, the market and prices for sulphur have been and may
continue to be volatile. The Company's operating margins and cash flow are
subject to substantial fluctuations in response to changes in supply and demand
for sulphur, conditions in the domestic and foreign agriculture industry, market
uncertainties and other factors beyond its control.
 
DEPLETION OF OIL AND GAS RESERVES
 
    Approximately 16.7% of the Company's 1996 revenues and 73.4% of its 1996 net
income were generated from the sale of oil recovered from Main Pass. Oil
revenues are expected to decline substantially in 1997 and subsequent years, and
the Company currently estimates that proved oil reserves at the Main Pass site
will be depleted by the year 2001. The Main Pass site is the Company's only oil
and gas property, and the Company currently does not intend to pursue oil and
gas exploration activities after the Main Pass reserves are depleted.
 
ABSENCE OF INDEPENDENT OPERATING HISTORY
 
    In recent years the Company's operations have been conducted by FRP, FTX and
their predecessors as part of a diversified business that was partly integrated
with FRP's other business activities and not as a stand-alone business.
Following the Distributions, the Company will be an independent entity engaged,
except for the production of oil and gas at the Main Pass operations,
exclusively in the sulphur business, and neither FRP nor FTX will have any
obligation to provide financial or operational support to the Company.
 
LIMITED RELEVANCE OF HISTORICAL FINANCIAL INFORMATION
 
    Because the Company has not been operated in recent years as an independent
entity, the historical financial information included herein was derived from
the audited financial statements of the FRP Transferred Businesses and is not
necessarily indicative of the results of operations, financial position and cash
flows that would have been achieved if the Company had been an independent
entity during the periods presented or that will be achieved in the future. The
Company's operations were an integral part of FRP's operations during the
periods covered by the historical financial statements included herein, and
certain historical financial data included herein has been extracted from FRP's
books and records based on allocations between FRP's sulphur and oil operations
and FRP's other businesses, and based on other assumptions necessary to reflect
the Company's operations as if they had been operated as an independent
enterprise. Additionally, the historical financial information included herein
does not give effect to the contribution of the IGL Transferred Businesses,
which is presented only on a pro forma basis. See "Pro Forma Financial
Statements (Unaudited) of Freeport-McMoRan Sulphur Inc.," including the
discussion of
 
                                       11
<PAGE>
the assumptions reflected therein, and "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
ABSENCE OF TRADING MARKET
 
    There is currently no trading market for the Company's Common Stock and
there can be no assurance that any such market will be established or
maintained. The Company has applied for listing of the Common Stock on the NYSE.
Even if an active trading market develops for the Common Stock, there can be no
assurance that its trading volume will be adequate to assure liquidity of a
stockholder's investment.
 
TAXABLE RECEIPT OF FREEPORT SULPHUR COMMON STOCK
 
   
    An FTX stockholder will recognize gain, if any, but not loss, realized on
the exchange of FTX Common Stock pursuant to the Merger to the extent of the
value of the Common Stock and any cash received in lieu of a fractional share of
Common Stock. While not free from doubt due to the absence of controlling
precedent, the character of the gain recognized by an FTX stockholder who is not
also an IGL stockholder arising from the receipt pursuant to the Merger of
Common Stock and any cash in lieu of a fractional share of Common Stock should
constitute capital gain, rather than dividend income, assuming that such
stockholder holds the FTX Common Stock as a capital asset. FTX stockholders who
are also stockholders of IGL should consult their tax advisors for special
considerations that may apply in regard to the receipt of Common Stock or cash
in lieu of a fractional share thereof.
    
 
DIVIDENDS
 
    The Company intends to retain earnings to meet its working capital needs and
finance its continuing operations. Thus, the Company does not plan to pay cash
dividends to its stockholders for the foreseeable future. See "Dividend Policy."

    The Company's reporting of proved sulphur and oil and gas reserves is based
upon engineering estimates. Reserve engineering is a subjective process of
estimating the recovery from underground accumulations of sulphur, oil and
natural gas that are not susceptible to exact measurement, and the accuracy of
any reserve estimate is a function of the quality of available data and of
engineering and geological interpretation and judgment. Estimates of
economically recoverable sulphur and oil and gas reserves and of future net cash
flows necessarily depend upon a number of variable factors and assumptions, such
as historical production from the area compared with production from other
producing areas, the assumed effects of governmental regulations and assumptions
concerning future sulphur and oil and gas prices, future operating costs,
severance and excise taxes, development costs and workover and remedial costs,
all of which may vary considerably from actual results. Because all reserve
estimates are to some degree speculative, the quantities of sulphur and oil and
natural gas that are ultimately recovered, production and operating costs, the
amount and timing of future development and reclamation expenditures, and future
sulphur and oil and natural gas sales prices may all vary materially from those
assumed in these estimates. In addition, different reserve engineers may make
different estimates of reserve quantities and cash flows based on the same data.
All of the Company's sulphur reserves are considered proved because of extensive
drilling and production experience; nevertheless, reserves are estimates and the
amount of sulphur actually produced may vary from the estimates, and such
variances could be material.
 
    The present values of estimated future net cash flows referred to in this
Prospectus should not be construed as the current market value of the Company's
estimated proved oil and gas reserves. In accordance with applicable
requirements of the Commission, the estimated discounted future net cash flows
from proved reserves are generally based on prices and costs as of the date of
the estimate, while actual future prices and costs may be materially higher or
lower. Actual net cash flows also will be affected
 
                                       12
<PAGE>
by factors such as the amount and timing of production, supply and demand for
oil and gas, curtailments or increases in consumption by gas purchasers and
changes in governmental regulations and taxation. The timing of future net cash
flows from proved reserves, and thus their actual present value, will be
affected by the timing of production and the incurrence of expenses in the
development and production of oil and gas properties. In addition, the 10%
discount factor required by the Commission to be used to calculate discounted
future net cash flows for reporting purposes is not necessarily the most
appropriate discount factor based on interest rates in effect from time to time
and risks associated with the oil and gas reserves owned by the Company or the
oil and gas industry in general.
 
ENVIRONMENTAL MATTERS
 
    The Company's operations include exploration, mining, development and
production of natural resources, and the extraction, handling, production,
storage, transportation and disposal of materials and waste products that may be
toxic or hazardous. Consequently, the Company is subject to numerous
environmental laws and regulations. The Company has incurred, and expects to
continue to incur, significant capital expenditures and operating expenses based
on these laws and regulations. Continued governmental and public emphasis on
environmental issues may result in increased capital and operating costs in the
future, although the impact of future laws and regulations or future changes to
existing laws and regulations cannot be predicted or quantified.
 
    Federal legislation (sometimes referred to as "Superfund" legislation)
imposes liability, without regard to fault, for clean-up of certain waste sites,
even though waste management activities at the site may have been performed in
compliance with regulations applicable at the time. Under the Superfund
legislation, one responsible party may be required to bear more than its
proportional share of clean-up costs if payments cannot be obtained from other
responsible parties. In addition, federal and state regulatory programs and
legislation mandate clean-up of certain wastes at operating sites. Governmental
authorities have the power to enforce compliance with these regulations and
permits, and violators are subject to civil and criminal penalties, including
fines, injunctions or both. Third parties also have the right to pursue legal
actions to enforce compliance. Liability under these laws can be significant and
unpredictable.
 
    The Company may receive in the future notices from governmental agencies
that it is one of many potentially responsible parties at certain sites under
relevant federal and state environmental laws. Some of these sites may involve
significant clean-up costs. The ultimate settlement of liability for the
clean-up of such sites usually occurs many years after the receipt of notices
identifying potentially responsible parties because of the many complex,
technical and financial issues associated with site clean-up. The Company cannot
predict its potential liability for clean-up costs that it may incur in the
future.
 
    The recent trend toward stricter standards in environmental legislation and
regulation is likely to continue. For instance, legislation has been proposed in
Congress from time to time that would reclassify certain crude oil and natural
gas exploration and production wastes as "hazardous wastes," which would make
the wastes subject to significantly more stringent handling, disposal and
clean-up requirements. If such legislation were to be enacted, it could have a
significant impact on the Company's operating costs, as well as the oil and gas
industry in general. Initiatives to further regulate the disposal of crude oil
and natural gas wastes are also pending in certain states and could have a
similar impact. In addition to compliance costs, government entities and other
third parties may assert substantial liabilities against owners and operators of
oil and gas properties for oil spills, discharges of hazardous materials,
remediation and clean-up costs and other environmental damages, including
damages caused by previous property owners. The imposition of any such
liabilities on the Company could have a material adverse effect on the Company's
financial condition and results of operations.
 
    The Oil Pollution Act of 1990 imposes a variety of regulations on
"responsible parties" related to the prevention of oil spills. The
implementation of new, or the modification of existing, environmental laws or
 
                                       13
<PAGE>
regulations, including regulations promulgated pursuant to the Oil Pollution Act
of 1990, could have a material adverse impact on the Company.
 
    In connection with the Contribution, the Company has assumed responsibility
for potential liabilities, including environmental liabilities, associated with
the prior conduct of the Transferred Businesses. Among these are potential
liabilities arising from sulphur mines that were depleted and closed in the past
in accordance with reclamation and environmental laws in effect at the time,
particularly in coastal or marshland areas that have experienced subsidence or
erosion. The Company believes that it is in compliance with existing laws
regarding such closed operations, and has implemented controls in some areas
that it believes exceed its legal responsibilities. Nevertheless, it is possible
that new laws or actions by governmental agencies could result in significant
unanticipated additional reclamation costs. For additional information regarding
certain reclamation obligations, see "Business--Environmental Matters."
 
    The Company could also be subject to potential liability for personal injury
or property damage relating to wellheads and other materials at closed mines in
coastal areas that have become exposed through coastal erosion. Although the
Company has insurance in place to protect it against certain of these
liabilities, there can be no assurance that such insurance coverage would be
sufficient. There can also be no assurance that the Company's current or future
accruals for reclamation costs will be sufficient to fully cover such costs.
 
OPERATING HAZARDS
 
    The Company's offshore sulphur mining, oil production and marine
transportation operations are subject to marine perils, including collisions,
hurricanes and other adverse weather conditions. All of the Company's oil and
sulphur production activities are subject to blowouts, cratering, fires and
other risks, any of which could result in serious personal injury or death and
substantial damage to property and the environment. The Company's operations may
be subject to significant interruption, and the Company may be subject to
significant liability, due to industrial accidents, severe weather or other
natural disasters occurring at one or more of its mining operations.
 
    The Company has in place, through FM Services Company ("FMS"), a company
that, prior to the Distributions was an affiliate of FTX and FRP and subsequent
to the Distributions will be 25% owned by the Company, certain liability,
property damage, business interruption and other insurance coverages in types
and amounts that it considers reasonable and believes to be customary in the
Company's business. This insurance provides protection against loss from some,
but not all, potential liabilities incident to the ordinary conduct of the
Company's business, including coverage for certain types of damages associated
with environmental and other liabilities that arise from sudden, unexpected and
unforeseen events, with such coverage limits, retentions, deductibles and other
features as management deems appropriate. The occurrence of an event that is not
fully covered by insurance could have a material adverse effect on the Company's
financial condition and results of operations.
 
DEPENDENCE ON MANAGEMENT AND ADMINISTRATIVE SERVICES
 
    The Company depends on certain management and administrative services
provided by FMS. Pursuant to a management services agreement (the "Services
Agreement") between the Company and FMS, FMS manages and supports certain of the
Company's operations. The Services Agreement does not assure the Company
unlimited access to all of the executive officers listed under "Management," and
there may be competition between the Company and its former affiliates for the
time and effort of the employees of FMS who provide services to the Company. If
the Company were deprived of adequate access to certain key members of its
management team or other personnel, or lost access to such services altogether,
the Company's results of operations could be materially and adversely affected.
See "Certain Transactions."

<PAGE>
ANTI-TAKEOVER MEASURES
 
    The Company's charter documents contain provisions that may have the effect
of discouraging a proposal for a takeover of the Company in which the Company's
stockholders could receive a substantial premium for some or all of their
shares. These provisions, among other things, authorize the issuance of "blank
check" preferred stock and divide the board of directors into three classes,
serving three-year staggered terms. The Company also intends to enter into a
Stockholder Protection Rights Agreement (the "Rights Agreement"), pursuant to
which each share of Common Stock will have an associated preferred stock
purchase right that, if triggered by the acquisition of 15% or more of the
outstanding Common Stock, would have the effect of significantly increasing the
cost to a potential acquiror of a takeover of the Company. In addition, the
Company is subject to certain provisions of Delaware law that limit, in some
cases, the ability of the Company to engage in certain business combinations
with significant stockholders. Such provisions, either alone, or in combination
with each other and the Rights Agreement, may give the Company's current
directors and executive officers a substantial ability to influence the outcome
of a proposed takeover. See "Description of Capital Stock--Certain Charter and
By-law Provisions."

                        THE MERGER AND THE DISTRIBUTIONS
 
   
    THE FOLLOWING DESCRIPTIONS OF THE MERGER AGREEMENT AND THE DISTRIBUTION
AGREEMENT DO NOT PURPORT TO BE COMPLETE AND ARE QUALIFIED IN THEIR ENTIRETY BY
REFERENCE TO SUCH DOCUMENTS, COPIES OF WHICH ARE ATTACHED AS ANNEX I TO THE
PROXY STATEMENT, AND AS AN EXHIBIT TO THE REGISTRATION STATEMENT OF WHICH THIS
PROSPECTUS FORMS A PART, RESPECTIVELY. ALL FTX STOCKHOLDERS ARE URGED TO READ
THE MERGER AGREEMENT AND THE DISTRIBUTION AGREEMENT IN THEIR ENTIRETY.
    
 
THE MERGER
 
    The Common Stock being registered pursuant to the Registration Statement of
which this Prospectus forms a part is being delivered to FTX stockholders in
connection with the Merger. As more fully described in the Proxy Statement under
the caption "The Merger," at the Effective Time, FTX will be merged with and
into IGL with IGL as the surviving corporation, and each outstanding share of
FTX Common Stock (other than shares owned directly or indirectly by IGL or FTX,
which will be canceled, or shares owned by any stockholder of FTX who is
entitled to and properly exercises appraisal rights under the Delaware General
Corporation Law (the "DGCL")) will be converted into the right to receive (i)
0.90 of a share of IGL Common Stock; (ii) one-third of a warrant to purchase a
share of IGL Common Stock, with each whole warrant representing a right to
purchase one share of IGL Common Stock for $44.50 per share and (iii) a
proportionate number of shares of Common Stock that will be held by FTX
immediately prior to the Effective Time. Under the terms of the Merger
Agreement, the shares of Common Stock received by FTX in the FRP Distribution
will be delivered to holders of FTX Common Stock as of the Effective Time. See
"--The Distribution Agreement--The Distributions." FTX stockholders will receive
cash in lieu of any fractional shares of Common Stock distributable in the FTX
Stockholder Distribution.
 
BACKGROUND OF AND REASONS FOR THE DISTRIBUTIONS
 
    Prior to entering into the Merger Agreement, each of FTX and IGL possessed a
significant indirect investment in IMC-Agrico, a phosphate fertilizer joint
venture, and also possessed a significant interest in the Main Pass operations,
which involve the mining and production of sulphur and the production of oil and
natural gas from deposits at the Main Pass site. During the course of
negotiating the Merger, it became apparent to FTX's management that IGL's
principal interest in pursuing the proposed Merger was in consolidating its
ownership and control of the IMC-Agrico operations, and that IGL was unlikely to
assign a value to the sulphur segment of FTX and FRP's business that would be
acceptable to FTX. As a result, FTX concluded that a better way of assuring that
the FTX stockholders would receive adequate value for the sulphur segment was to
spin off such assets to the owners of FRP including, ultimately, the
stockholders of FTX as part of the Merger consideration. For a discussion of the
background of and FTX's reasons for the Merger, see the Proxy Statement, to
which this Prospectus is attached.
 
THE DISTRIBUTION AGREEMENT
 
    THE CONTRIBUTION
 
    The Distribution Agreement provides for the transfer to the Company of
certain assets of IGL, FTX and FRP and the assumption by the Company of certain
liabilities related to those assets. The assets to be received by the Company in
the Contribution include substantially all of the assets used by FRP in the
production, marketing and distribution of sulphur, including its interest in the
Main Pass operations, as well as the oil and gas production operations at Main
Pass. Pursuant to the Merger Agreement and under the terms of a separate
contribution agreement, IGL's 25% interest in the Main Pass operations will also
be transferred to FRP, which in turn will contribute that interest to the
Company. The liabilities assumed by the Company are generally those liabilities
associated with the ownership, acquisition, conduct or past operation of the
assets received in the Contribution. See "Business."
 
                                       16
<PAGE>
    THE DISTRIBUTIONS
 
    The Distribution Agreement provides that the FRP Distribution will be
effected through the distribution to each holder of record of units of
partnership interests in FRP as of the close of business on the record date for
the FRP Distribution of one share of the Company's Common Stock for every 10
units of partnership interest held. In the FTX Stockholder Distribution, the FTX
stockholders of record as of the Effective Time of the Merger will receive their
pro rata share of the Common Stock received by FTX in the FRP Distribution. The
FRP Distribution will not be effected until approval of the Merger by the
stockholders of FTX and IGL has been received and all other conditions to the
Merger (other than the FRP Distribution) have been satisfied or waived, and the
FTX Stockholder Distribution will not be effected until the FRP Distribution and
the Merger have been consummated.
 
    FRP will distribute 10,346,578 shares of Common Stock in the FRP
Distribution, of which 51.6% or 5,338,513 shares will be distributed to FTX and
48.4% or 5,008,065 shares will be distributed to the FRP public unitholders. All
of the shares of Common Stock received by FTX will be delivered to the FTX
stockholders in the FTX Stockholder Distribution. Based on the approximately
25.1 million shares of FTX Common Stock outstanding as of the date of this
Prospectus, the FTX stockholders will receive approximately 0.2123 of a share of
Common Stock for each share of FTX Common Stock held (or approximately 0.1980 of
a share of Common Stock for each share of FTX Common Stock held if all
outstanding options to purchase FTX Common Stock were exercised on or prior to
the Effective Time.) If all outstanding options to acquire FTX Common Stock that
are "in the money" as of the date of this Prospectus were exercised, there would
be 25.9 million shares of FTX Common Stock outstanding and the exchange ratio
would be 0.2064 of a share of Common Stock for each share of FTX Common Stock.
As a result of the Distributions, the FRP public unitholders and the FTX
stockholders will own all of the outstanding shares of Common Stock of the
Company.
 
    Under the terms of the Distribution Agreement, the Distribution Agent for
each of the FRP Distribution and the FTX Stockholder Distribution will aggregate
any fractional shares of Common Stock otherwise distributable in connection with
the FRP Distribution and the FTX Stockholder Distribution, respectively, sell
them in the open market, and make a pro rata distribution of the proceeds of
such sales to FRP public unitholders or FTX stockholders, as appropriate, who
would otherwise have received a fractional share in the FRP Distribution or the
FTX Stockholder Distribution.
 
    MUTUAL INDEMNITIES
 
    The Distribution Agreement provides that FTX and FRP on the one hand and the
Company on the other will indemnify one another against certain losses, damages,
claims and liabilities assumed or retained by the indemnifying party. Among
other things, FTX and FRP are obligated to indemnify the Company for an
indefinite period against losses related to (i) the failure by FRP or FTX to
perform their respective obligations under the Distribution Agreement, (ii)
liabilities associated with any FRP assets not transferred to, and liabilities
not assumed by, the Company , (iii) taxes relating to the operation of the
Transferred Businesses prior to the Contribution, and (iv) the breach of any
representation or warranty by FRP or FTX contained in the Distribution
Agreement. The Company is obligated to indemnify FRP and FTX for an indefinite
period against (i) the failure by the Company to perform its obligations under
the Distribution Agreement, (ii) liabilities associated with any FRP assets
transferred to the Company pursuant to the Contribution, and liabilities
associated with the operation of the Transferred Businesses prior to the
Contribution, (iii) taxes relating to the operation of the Transferred
Businesses after the Contribution and (iv) the breach of any representation or
warranty of the Company contained in the Distribution Agreement.

THE SOLVENCY OPINION
    
 
   
    The Company and FTX have received the opinion of Valuation Research
Corporation that the FRP Distribution does not violate certain provisions of
Delaware limited partnership law regarding the making of distributions and,
after giving effect to the Contribution and the Distributions, that the Company
(i) will be solvent after taking into account the liabilities and obligations
undertaken in connection with and as a result of the Contribution, (ii) will be
able to pay its debts and liabilities as they become due, and (iii) will not be
left with insufficient capital with which to engage in its businesses. Receipt
of this opinion is a condition precedent to the consummation of the Merger. A
copy of the opinion has been filed as an exhibit to the Registration Statement
of which this Prospectus forms a part.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
   
    The following discussion is the opinion of Miller & Chevalier, Chartered,
tax counsel to FTX and addresses all material United States federal income tax
consequences of the receipt by the FTX stockholders of the Company's Common
Stock in the Merger. The opinion that will be rendered has been filed as an
exhibit to the Registration Statement of which this Prospectus forms a part. An
opinion of counsel is not binding on the IRS or the courts, and no assurance can
be given that the IRS will not challenge the treatment of certain matters
discussed herein or, if it does, that it will not be successful. The discussion
does not address any tax consequences of the receipt of Common Stock under
applicable state, local or foreign tax laws. The discussion is based on the
provisions of the Internal Revenue Code of 1986, as amended (the "Code"), final
and proposed Treasury regulations, administrative positions of the IRS, and
court decisions in effect on the date of this Prospectus. All of the foregoing
are subject to change, possibly with retroactive effect.
    
 
    The summary is included for general information purposes only and does not
address all aspects of federal income taxation that may be relevant to a
particular stockholder in light of his or its personal tax circumstances or all
of the tax consequences that may be relevant to certain types of stockholders
subject to special treatment under the federal income tax laws (such as
individual retirement accounts, insurance companies, and tax-exempt
organizations). The summary also does not address the tax consequences to
subsequent purchasers of the Common Stock and is limited to stockholders who
will hold the Common Stock as capital assets within the meaning of section 1221
of the Code. FTX stockholders should consult their own tax advisors as to the
specific tax consequences to them of the Merger and with respect to the effects
of any state, local, or foreign tax laws to which they may be subject.
 
RECEIPT OF FREEPORT SULPHUR COMMON STOCK IN THE MERGER
 
    FTX stockholders will receive shares of Common Stock as part of the
consideration in the Merger. Each stockholder will recognize gain, if any, but
not loss, on the Merger to the extent of the fair market value of the shares of
Common Stock (including the amount of cash received in lieu of a fractional
share) received in the Merger. IGL will determine the fair market value of the
Common Stock based on the average trading prices of such stock during a
representative period on or following the Effective Time. IGL's determination of
the fair market value of the Common Stock is not binding on the IRS.
 
    Capital gains realized by individuals (but not corporations) are taxed at
preferential rates, while corporate (but not individual) stockholders may be
eligible for tax relief in the form of a dividends received deduction with
respect to dividends received from another corporation. While not free from
doubt due to the absence of controlling precedent, the gain recognized by an FTX
stockholder who is not also an IGL stockholder arising from the receipt of
Common Stock (and cash in lieu of a fractional share) pursuant to the Merger
should constitute capital gain, rather than dividend income, assuming that the
stockholder held the FTX Common Stock with respect to which the Common Stock is
received as a capital asset. FTX stockholders who also own IGL Common Stock
should consult their own tax advisors for special considerations that may apply
in regard to the receipt of Common Stock or cash in lieu of a fractional share
thereof. An individual stockholder's capital gain will be taxable at a maximum
federal income tax rate of 20% or 28%, if the FTX stockholder has held the
surrendered shares of FTX Common Stock for more than 18 months or 12 months,
respectively, as of the Effective Time.
 
    The basis for the Common Stock received by an FTX stockholder will be equal
to its fair market value as of the Effective Time (determined as provided
above). The stockholders' holding periods for the Common Stock will begin on the
day after the Effective Time.
 
SALE OR EXCHANGE OF COMMON STOCK
 
    In general, any gain or loss from the sale or exchange of the Common Stock
will be characterized as capital gain or loss. The gain or loss will be measured
by the difference between the amount realized on the
 
                                       19
<PAGE>
sale and the stockholder's adjusted tax basis in the Common Stock. An individual
stockholder's capital gain generally will be taxed at a maximum rate of 20% if
the stockholder has owned the Common Stock for more than 18 months at the time
of the sale, or a maximum rate of 28% if the stockholder has owned the Common
Stock for more than 12 months but not more than 18 months at the time of the
sale.
 
TAX TREATMENT OF INCOME OR LOSS OF FREEPORT SULPHUR
 
    The Company will be treated as a corporation for federal income tax purposes
and its income will be subject to the federal corporate income tax.
 
DISTRIBUTIONS FROM FREEPORT SULPHUR
 
    Distributions of cash or other property by the Company with respect to the
Common Stock will be dividends to the extent they represent current or
accumulated earnings and profits as determined for federal income tax purposes.
To the extent that a distribution exceeds the Company's earnings and profits, it
will be treated first as a nontaxable return of capital to a stockholder and
then as capital gain if the amount exceeds the stockholder's basis in the Common
Stock. Dividends received by corporate holders may be eligible for the corporate
dividends received deduction, subject to the conditions and limitations
applicable to the deduction, and in certain circumstances may be extraordinary
dividends within the meaning of Code section 1059. Corporate stockholders should
consult their own tax advisors regarding the dividends received deduction and
extraordinary dividend rules. It should be noted, however, that the Company
intends to retain earnings to meet its working capital needs and finance its
continuing operations, and does not expect to pay dividends on its Common Stock
for the foreseeable future. See "Dividend Policy."
 
NON-U.S. HOLDERS
 
    The following summary addresses certain United States federal income and
estate tax consequences of the receipt, ownership and disposition of Common
Stock by a Non-U.S. Holder. Generally, for purposes of this discussion, a
"Non-U.S. Holder" is a beneficial owner of Common Stock who or which is, for
United States federal income tax purposes, a non-resident alien individual, a
foreign corporation, a foreign partnership, or a foreign estate or trust.
Different rules apply for United States federal estate tax purposes. See
"--Federal Estate Taxes," below.
 
   
    RECEIPT OF COMPANY COMMON STOCK IN THE MERGER AND SALE OR EXCHANGE OF COMMON
     STOCK
    
 
    A Non-U.S. Holder will not be subject to United States federal income tax on
any gain realized on the receipt of Common Stock (or cash in lieu of a
fractional share thereof) pursuant to the Merger or on the subsequent sale or
exchange of Common Stock unless (a) the gain is derived from sources within the
United States and the Non-U.S. Holder is a nonresident alien individual who is
present in the United States for 183 days or more during the taxable year in
which the gain is realized; (b) the Non-U.S. Holder is subject to tax pursuant
to the provisions of the United States federal tax law applicable to certain
United States expatriates; (c) the gain is effectively connected with the
conduct of a trade or business within the United States; or (d) the FTX Common
Stock or the Common Stock is a "United States Real Property Interest" as defined
in section 897(c)(1) of the Code and at any time during the five years prior to
the Merger or sale, the Non-U.S. Holder held, directly or constructively more
than 5 percent of the FTX Common Stock or the Common Stock, as the case may be.
The 183-day rule referred to above only applies in limited circumstances because
generally an individual present in the United States for 183 days or more in the
taxable year of the sale, exchange, or other disposition will be treated as a
resident for United States federal income tax purposes and therefore will be
subject to United States federal income tax at graduated rates applicable to
individuals who are United States persons for such purposes.
 
                                       20
<PAGE>
    Non-U.S. Holders should consult applicable tax treaties, which may result in
United States federal income tax treatment on the sale, exchange or other
disposition of stock different than as described above.
 
   
    DIVIDENDS ON COMMON STOCK
    
 
    Subject to the discussion below, dividends paid to a Non-U.S. Holder will be
subject to withholding of United States federal income tax at a rate of 30% of
the gross amount of such dividends or at such lower rate as may be specified by
an applicable tax treaty. Proposed United States Treasury Regulations were
issued on April 15, 1996 (the "Proposed Regulations"), which, if adopted, could
affect the United States taxation of dividends on Common Stock paid to a
Non-U.S. Holder by changing certain presumptions under current law and
regulations upon which the Company may generally rely in determining whether, in
the absence of documentation, a Non-U.S. Holder should be treated as qualified
for the benefits of an applicable tax treaty. Dividends received by a Non-U.S.
Holder that are effectively connected with the conduct of a United States trade
or business of the Non-U.S. Holder will be exempt from the 30% withholding tax,
but will be subject to United States federal income tax at graduated rates as if
the Non-U.S. Holder were a United States person for federal income tax purposes.
Non-U.S. Holders should consult their own tax advisors regarding the United
States federal income taxation of any dividends, including the application of
any treaties to such dividends. It should be noted, however, that the Company
intends to retain earnings to meet its working capital needs and finance its
continuing operations, and does not expect to pay dividends on its Common Stock
for the foreseeable future. See "Dividend Policy."
 
   
    BACKUP WITHHOLDING TAX AND INFORMATION REPORTING
    
 
    Generally, the Company must report to the IRS the amount of dividends paid,
the name and address of the recipient, and the amount, if any, of United States
federal income tax withheld. A similar report is sent to the holder. Pursuant to
tax treaties or other agreements, the IRS may make its reports available to tax
authorities in the recipient's country of residence.
 
    Unless the Company has actual knowledge that a holder is a Non-U.S. Holder,
dividends paid to a holder of Common Stock at an address within the United
States may be subject to backup withholding at a rate of 31% if the holder is
not an "exempt recipient" as defined in existing Treasury Regulations (which
includes corporations) and fails to provide a correct taxpayer identification
number and other information to the Company. Backup withholding will generally
not apply to dividends paid to holders at an address outside the United States
(unless the Company has knowledge that the holder is a United States person for
United States federal income tax purposes).
 
    Proceeds from a disposition of Common Stock by a Non-U.S. Holder effected by
or through a United States office of a broker will be subject to information
reporting and to backup withholding at a rate of 31% of the gross proceeds,
unless such Non-U.S. Holder certifies under penalties of perjury as to, among
other things, his or its name, address and status as a Non-U.S. Holder or
otherwise establishes an exemption. Generally, United States information
reporting and backup withholding will not apply to a payment of disposition
proceeds if the transaction is effected outside the United States by or through
a non-United States office of a broker. However, United States information
reporting requirements (but not backup withholding) will apply to a payment of
disposition proceeds where the transaction is effected outside the United States
if (a) the disposition is made by or through an office outside the United States
of a broker that is either (i) a United States person for United States federal
income tax purposes, (ii) a "controlled foreign corporation" for United States
federal income tax purposes, or (iii) a foreign person which derives 50% or more
of its gross income for certain periods from the conduct of a United States
trade or business and (b) the broker fails to maintain documentary evidence in
its files that the holder is a Non-U.S. Holder and that certain other conditions
are met or that the holder otherwise is entitled to an exemption.

    The Proposed Regulations would, if adopted, alter the foregoing rules in
certain respects. Among other things, the Proposed Regulations would provide
certain presumptions and other rules under which Non-U.S. Holders may be subject
to backup withholding in the absence of required certifications and would revise
the definition of an "exempt recipient" in the case of a corporation.
 
    Backup withholding is not an additional tax. Rather, the tax liability of
persons subject to 31% backup withholding will be reduced by the amount of tax
withheld. If withholding results in an overpayment of United States federal
income taxes, a refund may be obtained, provided that the required information
is furnished to the IRS.
 
   
    FEDERAL ESTATE TAXES
    
 
    An individual Non-U.S. Holder who is treated as the owner of Common Stock at
the time of his death, or has made certain lifetime transfers of an interest in
Common Stock, will be required to include the value of such Common Stock in his
gross estate for United States federal estate tax purposes and may be subject to
United States federal estate tax, unless an applicable treaty provides
otherwise. For United States federal estate tax purposes, a "Non-U.S. Holder" is
an individual who is neither a citizen nor a domiciliary of the United States.
Whether an individual is considered a "domiciliary" of the United States for
federal estate tax purposes is generally determined on the basis of all of the
facts and circumstances.

                                DIVIDEND POLICY
 
    The Company currently intends to retain its earnings to meet its working
capital requirements and finance its business operations and does not plan to
pay cash dividends to its stockholders for the foreseeable future. Any future
determination to pay cash dividends will be made by the Board of Directors in
light of Company's earnings, cash flow, financial position, capital
requirements, credit agreements and such other factors as the Board of Directors
deems relevant at that time.
 
                          DISTRIBUTING SECURITY HOLDER
 
    All of the shares of Common Stock being delivered hereby have been received
by FTX in the FRP Distribution and are being distributed to FTX stockholders in
the FTX Stockholder Distribution in accordance with the terms of the Merger
Agreement. No cash consideration is being paid by FTX stockholders in connection
with the FTX Stockholder Distribution and neither the Company nor FTX will
receive any proceeds from the FTX Stockholder Distribution.

                     SELECTED FINANCIAL AND OPERATING DATA
 
    The selected financial data provided below reflect the historical results of
operations and financial position of the FRP Transferred Businesses only and do
not include the IGL Transferred Businesses. The historical financial information
is not necessarily indicative of the financial position and results of
operations that would have been achieved had the Company been operated as an
independent entity during the periods covered or the results that may be
achieved in the future. Historical net income and dividend per share amounts are
not presented because the FRP Transferred Businesses were operated through
divisions of FRP for the periods presented. See "Risk Factors--Limited Relevance
of Historical Financial Information."
 
   
    The following selected financial data as of December 31, 1996 and 1995 and
for each of the years in the three-year period ended December 31, 1996 has been
derived from the audited financial statements of the FRP Transferred Businesses
and does not include the IGL Transferred Businesses. The selected financial data
as of December 31, 1994, 1993 and 1992 and for each of the years in the two-year
period ended December 31, 1993 are unaudited and were derived from the
accounting records of FRP. The selected financial data as of and for each of the
nine-month periods ended September 30, 1997 and 1996, have been derived from the
unaudited financial statements of the FRP Transferred Businesses, and in the
opinion of management includes all adjusting entries (consisting only of normal
recurring adjustments), necessary for a fair presentation of the results of the
periods presented.
    
 
    The selected financial information of the FRP Transferred Businesses set
forth below should be read in conjunction with "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and the historical

- ------------------------------
 
(1) As a partnership, FRP pays no federal or state income taxes and historically
    has not provided for income taxes for the FRP Transferred Businesses. Pro
    forma net income includes an estimated tax provision for the applicable
    periods as if the FRP Transferred Businesses operated as a stand-alone
    taxpaying entity.
 
   
(2) In 1995, the Financial Accounting Standards Board adopted SFAS No. 121,
    which requires an assessment of the carrying value of long-lived assets and
    a reduction of such carrying value to fair value when events or changes in
    circumstances indicate that the carrying amount of such assets may not be
    recoverable. In the third quarter of 1997, FRP and FTX determined that the
    sulphur assets were impaired within the meaning of SFAS No. 121 because
    their book value exceeded the estimated undiscounted net cash flow
    recoverable with respect thereto. Accordingly, in the third quarter of 1997,
    FRP and FTX recorded an impairment writedown totaling $425.4 million to
    reduce these properties to their fair value (measured by the difference
    between the carrying value of such assets and the current discounted value
    of future net cash flows).
    
 
   
(3) Includes charges totaling $7.0 million allocated to the FRP Transferred
    Businesses to reflect a compensation charge related to FTX stock
    appreciation rights, which was attributable to the significant rise in the
    price of FTX Common Stock during such period. Pursuant to a management
    services agreement with FTX, these costs were allocated to FRP, and thus to
    the FRP Transferred Businesses, based on payroll costs.
    
 
   
(4) Includes charges totaling $11.6 million for restructuring and other related
    charges.

(3) EBITDA represents net income before income taxes plus depreciation and
    amortization expense. EBITDA is not a measure of cash flow, operating
    results or liquidity as determined by generally accepted accounting
    principles. The Company has supplementally disclosed information concerning
    EBITDA because management believes that EBITDA is commonly accepted as
    providing useful information regarding a company's historical ability to
    incur and service debt. Management of the Company believes that factors that
    should be considered by investors in evaluating EBITDA include but are not
    limited to, trends in EBITDA as compared to cash flow from operations, debt
    service requirements and capital expenditures. EBITDA as defined and
    measured by the Company may not be comparable to similarly titled measures
    of other companies. Further, EBITDA should not be considered in isolation or
    as an alternative to, or more meaningful than, net income or cash flow
    provided by operations as determined in accordance with generally accepted
    accounting principles as an indicator of the Company's profitability or
    liquidity.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
    The following Management's Discussion and Analysis of Financial Condition
and Results of Operations relates to the historical results of operations and
financial condition of the FRP Transferred Businesses only and does not include
the IGL Transferred Businesses. Such information should be read in conjunction
with the audited financial statements of the FRP Transferred Businesses and the
Pro Forma Financial Statements of Freeport-McMoRan Sulphur Inc. included
elsewhere herein. Prior to the Contribution, the Company's operations were
conducted as an integral part of FRP's operations, and certain historical
financial data has been extracted from FRP's books and records based on
allocations between the FRP Transferred Businesses and FRP's other businesses,
and based on other assumptions necessary to reflect the Company's operations as
if they had been conducted as an independent enterprise. The results of
operations described below are not necessarily indicative of the operating
results that the Company would have achieved on an independent basis or of
future operating results.
 
    The Company's business consists of the sale of sulphur, the marketing of
logistics services, the operation of two sulphur mines and a logistics system
consisting of sulphur transportation and terminaling assets. The Company's
operations include the Main Pass mine located offshore Louisiana in the Gulf of
Mexico, the Culberson mine located in west Texas, five sulphur terminals located
across the Gulf Coast, and marine and rail transportation assets. The oil
operations consist of FRP's interest in the Main Pass operations.
 
   
IMPAIRMENT ASSESSMENT OF SULPHUR ASSETS
    
 
   
    In 1995, the Financial Accounting Standards Board ("FASB") issued SFAS 121
which requires an assessment of the carrying value of long-lived assets and a
reduction of such carrying value to fair value when events or changes in
circumstances indicate that the carrying amount of such assets may not be
recoverable. As a result of its most recent review of its sulphur assets, FRP
and FTX concluded that the carrying value of the Main Pass sulphur assets
exceeded the undiscounted estimated future net cash flows, such that an
impairment writedown of $416.4 million (based on September 30, 1997 book values)
was required. A similar analysis of the Culberson mine sulphur assets, based on
a reassessment of recoverable reserves utilizing recent production history, also
indicated that a writedown of $9.0 million (based on September 30, 1997 book
values) was required. Fair values were estimated using discounted estimated
future net cash flows related to these assets. The writedowns to fair value were
recorded by FRP and FTX in the third quarter of 1997 and are reflected in the
unaudited September 30, 1997 financial statements as additional depreciation and
amortization charges. Future operating results of the Company will reflect lower
depreciation and amortization expense as a result of these writedowns.

    NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED WITH NINE MONTHS ENDED
     SEPTEMBER 30, 1996
    
 
   
    Sulphur operations reported a net loss of $429.2 million in the nine-month
1997 period compared with net income of $4.7 million for the 1996 period,
primarily because of the asset impairment charges and lower sulphur prices.
Sulphur realized prices for the 1997 period were 4% lower than the 1996 period.
Sulphur sales volumes for 1997 rose slightly from the 1996 period, primarily due
to increased sales to IMC-Agrico. Production levels at the Main Pass and
Culberson sulphur mines were reduced in early 1996 in response to lower domestic
demand for sulphur, and these mines continue to operate at curtailed levels.
Higher sales volumes in 1997 were met through inventory reductions and recovered
sulphur purchases. Combined production from the two mines averaged 7,600 tons
per day for the nine-month 1997 period compared with 8,000 tons per day for the
1996 period.
    
 
   
    Main Pass net income from oil and gas operations totaled $4.0 million in
1997 and $8.2 million in 1996 reflecting slightly lower average realizations and
reduced production levels. Current estimates are that the proved oil reserves at
the Main Pass site will be depleted by the year 2001.
    
 
   
    Production and delivery costs were higher in the 1997 period because of
higher sulphur sales volumes, energy costs and drilling costs. Depreciation and
amortization in the nine-month 1997 period includes the asset impairment
charges, but without the charges was lower compared with the 1996 period because
of the lower production rates. General and administrative expenses were lower in
the 1997 period compared with the 1996 period.
    
 
    1996 COMPARED WITH 1995
 
    Sulphur net income totaled $3.3 million for 1996 compared with $23.0 million
for 1995 primarily because of lower prices and volumes and slightly higher unit
costs. Sulphur sales volumes for 1996 were 5% lower than the 1995 level.
Production levels at the Main Pass and Culberson mines were reduced in early
1996 in response to lower domestic sulphur sales to U.S. phosphate fertilizer
producers. Production averaged 7,800 tons per day for 1996 compared with 8,500
tons per day in 1995. Sulphur market prices were 12% lower than the 1995 period,
reflecting lower demand from the phosphate fertilizer industry and
 
                                       28
<PAGE>
higher recovered sulphur supplies. Unit production costs for 1996 rose slightly
from 1995 levels because of the reduced production levels and increased energy
costs.
 
    Main Pass oil net income for 1996 totaled $9.1 million compared with $2.0
million for 1995. Despite lower sales volumes, net income benefited in 1996 from
a significant increase in average realizations caused by the overall rise in
world oil prices which occurred in mid-1996 and again in late 1996. Lower
production for 1996 reflected declining reservoir production levels.
 
    Production and delivery and depreciation and amortization costs were lower
in 1996 because of the reduced production levels. General and administrative
expenses were lower in 1996 primarily because of a $7.0 million charge ($5.2
million to sulphur operations and $1.8 million to oil operations) that was
allocated to the FRP Transferred Businesses to reflect a compensation charge
related to FTX stock appreciation rights, which was attributable to the
significant rise in the price of FTX Common Stock during such period. Pursuant
to a management services agreement with FTX, these costs were allocated to FRP,
and thus to the FRP Transferred Businesses, based on payroll costs.
 
    1995 COMPARED WITH 1994
 
    Sulphur net income totaled $23.0 million for 1995 compared with $4.3 million
for 1994. Sales increased by 46% due to the Company's acquisition in January
1995 of substantially all of Pennzoil's sulphur assets, including sales
contracts for approximately 900,000 long tons per year, and to the strengthening
in sulphur prices during 1995. Main Pass unit production costs for 1995 were
virtually unchanged from 1994.
 
    Main Pass oil net income was $2.0 million in 1995 compared with $3.1 million
in 1994. Lower production in 1995 was offset by higher average realized prices.
 
    Production and delivery and depreciation and amortization costs were higher
in 1995 primarily because of the Company's acquisition of Pennzoil's sulphur
assets in January 1995. General and administrative expenses were higher in 1995
primarily because of the FTX stock appreciation rights charges discussed above
and the Pennzoil acquisition.
 
CAPITAL RESOURCES AND LIQUIDITY
 
   
    Net cash provided by operating activities totaled $20.8 million for the
nine-month 1997 period, $41.5 million for the nine-month 1996 period, $51.8
million for 1996, $65.4 million for 1995 and $34.2 million for 1994. Lower net
income and increased working capital requirements resulted in lower net cash
provided by operating activities in the nine-month 1997 period compared with the
nine-month 1996 period. Net cash provided by operating activities in 1996 was
lower than in 1995 primarily because of lower net income. Net cash provided by
operating activities in 1995 was $31.2 million higher than in 1994 primarily
because of higher net income and lower reclamation and shutdown expenditures.
    
 
   
    Capital expenditures primarily relate to maintaining current levels of
production. Capital expenditures totaled $3.0 million for the nine-month 1997
period, $4.9 million for the nine-month 1996 period, $3.8 million for 1996, $3.7
million for 1995 and $11.2 million for 1994. Higher capital expenditures in 1994
related to drilling additional development wells at the Main Pass oil
operations. Proceeds from asset sales included certain warehousing and supply
assets of $0.9 million in the nine-month 1997 period, $1.2 million in the
nine-month 1996 period and $2.1 million in 1996 mostly from the sale of certain
marine assets, and $1.2 million from the sale of an airplane and certain marine
assets in 1994. Capital expenditures for 1997 are expected to be slightly higher
compared with 1996 and 1995 because of additional drilling activities scheduled
in 1997 to maintain required levels of water treatment capacity for the sulphur
operations. Funding for capital expenditures is provided by operating cash
flows.
    
 
    Based on current projections, management believes that the Company will
generate sufficient cash flow from operations to fund its ongoing working
capital requirements, reclamation costs and projected
 
                                       29
<PAGE>
capital expenditures for the foreseeable future. Additionally, the Company is in
discussions with various banks and expects to establish a revolving credit
facility to further enhance its liquidity and financial flexibility.
 
ENVIRONMENTAL
 
    The Company, through its predecessors, has a history of commitment to
environmental responsibility. Since the 1940s, long before public attention
focused on the importance of maintaining environmental quality, the Company has
conducted pre-operational, bioassay, marine ecological and other environmental
surveys to ensure the environmental compatibility of its operations. The
Company's environmental policy commits its operations to compliance with local,
state and federal laws and regulations, and prescribes the use of periodic
environmental audits of all facilities to evaluate compliance status and
communicate that information to management. The Company has access to
environmental specialists who have developed and implemented corporate-wide
environmental programs. The Company continues to study methods to reduce
discharges and emissions.
 
    Federal legislation (sometimes referred to as "Superfund" legislation)
requires payments for cleanup of certain waste sites, even though waste
management activities were performed in compliance with regulations applicable
at the time. Under the Superfund legislation, one party may, under certain
circumstances, be required to bear more than its proportional share of cleanup
costs at a site where it has responsibility pursuant to the legislation, if
payments cannot be obtained from other responsible parties. Other legislation
mandates cleanup of certain wastes at operating sites. States also have
regulatory programs that can mandate waste cleanup. Liability under these laws
involves inherent uncertainties.
 
   
    Estimated future expenditures to restore properties and related facilities
to a condition that complies with environmental and other regulations are
accrued over the life of the properties. The future expenditures are estimated
based on current costs, laws and regulations. As of September 30, 1997, the
Company had accrued $45.6 million ($17.0 million of which will be reimbursed by
third parties) for abandonment and restoration of its non-operating sulphur
assets and $8.1 million for the dismantling of the Main Pass oil operations.
Current liabilities include $11.5 million at September 30, 1997 for reclamation
and mine shutdown, $2.5 million of which will be reimbursed by third parties.
The Company's share of abandonment and restoration costs for its two operating
sulphur mines is estimated to total approximately $50 million, $18.8 million of
which had been accrued at September 30, 1997, with essentially all such costs
expected to be incurred after mine closure. These estimates are by their nature
imprecise and can be expected to be revised over time because of changes in
government regulations, operations, technology and inflation.
    
 
    The Company has made, and will continue to make, expenditures at its
operations for protection of the environment. Continued government and public
emphasis on environmental issues can be expected to result in increased future
investments for environmental controls, which will be charged against income
from future operations. Present and future environmental laws and regulations
applicable to current operations may require substantial capital expenditures
and may affect its operations in other ways that cannot now be accurately
predicted.
 
    The Company maintains insurance coverage in amounts deemed prudent for
certain types of damages associated with environmental liabilities that arise
from sudden, unexpected and unforeseen events.
 
CAUTIONARY STATEMENT
 
    This Prospectus contains forward-looking statements regarding the Company's
business strategy, reserve expectations, demand for sulphur, competition, the
availability of financing, the ability to satisfy future cash obligations, and
environmental costs. Important factors that might cause future results to differ
from these projections include the reliance on IGL and FRP as continuing
customers, the seasonality and volatility of sulphur markets, competition, and
environmental issues as described in more detail under "Risk Factors."

                                    BUSINESS
 
GENERAL
 
    Freeport Sulphur is a Delaware corporation formed in August 1997 to succeed
to the sulphur and certain oil and gas operations of FRP. Management believes
that Freeport Sulphur is the world's largest producer of mined, or "Frasch,"
sulphur and the largest supplier of elemental sulphur in the United States.
Pursuant to the Distribution Agreement, FRP will contribute to Freeport Sulphur
all of its sulphur operations, and certain of its oil and gas operations,
including FRP's 58.3% interest in the Main Pass operations and its sulphur mine
in Culberson County, Texas. In addition, in connection with the Merger, IGL will
transfer to FRP, which in turn will contribute to Freeport Sulphur, IGL's 25%
interest in the Main Pass operations, with the result that the Company will have
an 83.3% interest in the Main Pass operations, and Homestake will continue to
own the remaining 16.7% interest. The Company also will continue to serve as the
operator of the Main Pass operations. The Company's sulphur operations include
the mining, purchase, transportation, terminaling and marketing of sulphur. Its
oil and gas operations consist of the production and sale of oil and gas from
its Main Pass facilities.
 
    Sulphur, both in its elemental form and in the form of sulphuric acid, is
essential to agriculture and industry. Sulphur is a base element primarily used
in the production of sulphuric acid, which is used in the manufacture of
phosphate fertilizers and other agricultural chemicals, and has numerous
industrial applications, including ore and metal leaching, petroleum and mineral
refining, and chemical manufacturing. While sulphur is essential in almost every
segment of the economy, it is generally used as a processing agent and is seldom
apparent in the final product.
 
    Freeport Sulphur is the successor to a line of business that has been
conducted by FRP and its predecessors since 1912, making it the longest
continuously operating sulphur company in the United States. Since its founding,
the Company has introduced numerous innovations in the production and
transportation of sulphur, including the development of a mine in marsh terrain
near the mouth of the Mississippi River, the use of directional drilling (a
critical technique for exploiting offshore sulphur deposits), and the
development of technology for transporting molten sulphur, which has earned the
acceptance of U.S. sulphur consumers as an environmentally and economically
superior method. Freeport Sulphur was the first, and remains the only, company
to superheat seawater for sulphur mining, and in 1960 constructed the first
offshore sulphur mine, followed by a second offshore mine constructed in 1968,
and a third offshore mine with the construction of the Main Pass mine in 1992.
Freeport Sulphur remains the only company to successfully operate offshore
sulphur mines. Over its history, the Company has mined more than 160,000,000
long tons of sulphur, and in 1988 discovered the largest sulphur deposit in
North America at Main Pass in the Gulf of Mexico. Through its 1995 acquisition
of substantially all of the sulphur assets of Pennzoil, Freeport Sulphur became
the world's largest producer of mined sulphur and a leading supplier of sulphur
to the United States market, and positioned itself as having the industry's
largest molten sulphur handling system.
 
    The Main Pass sulphur deposit is the largest known sulphur reserve in North
America. The Company's Main Pass offshore mining complex is the largest
structure of its type in the Gulf of Mexico and one of the largest in the world,
and was designed to produce an average of 5,500 long tons per day over its life.
The Company began operating the Culberson mine in January 1995 following its
acquisition of substantially all of Pennzoil's domestic sulphur assets. As of
December 31, 1996, the Main Pass and Culberson mines were estimated to contain
proved sulphur reserves totaling 53.1 million long tons net to the Company (or
69.7 million long tons net to the Company on a pro forma basis after the
contribution of the IGL Transferred Businesses). In addition to the Culberson
mine, the Company also acquired from Pennzoil sulphur terminals and handling
facilities in Galveston, Texas and Tampa, Florida, land and marine
transportation equipment, and sales and other related commercial contracts and
obligations.
 
    The Company's principal business is the sale of sulphur and the marketing of
its terminaling and transportation assets for use by recovered sulphur producers
and industrial consumers of sulphur. The
 
                                       31
<PAGE>
   
phosphate fertilizer industry generally accounts for approximately 90% of the
Company's sulphur sales. The Company's 1996 sulphur sales were approximately 2.9
million long tons, representing 25% of domestic consumption (or 3.4 million long
tons, representing 30% of domestic consumption, on a pro forma basis after the
contribution of the IGL Transferred Businesses). Sales to IMC-Agrico, a
manufacturer of phosphate fertilizers and the largest purchaser of elemental
sulphur in the world, represented approximately 65% of the Company's sulphur
sales (or 71% on a pro forma basis after the contribution of the IGL Transferred
Businesses). Pursuant to a Sulphur Supply Agreement, the Company has agreed to
supply and IMC-Agrico has agreed to purchase approximately 75% of IMC-Agrico's
annual sulphur consumption for as long as IMC-Agrico has an operational need for
sulphur. The price per ton for all sulphur delivered under the agreement is
based upon the weighted average market price for sulphur delivered by other
sources to IMC-Agrico's New Wales production plant in central Florida, except
that the Company is entitled to a premium with respect to approximately 40% of
the sulphur that it delivers under the agreement. IMC-Agrico also pays a portion
of the freight costs associated with the delivery of sulphur under the
agreement. Management believes that the terms of the Sulphur Supply Agreement
are no less favorable to the Company than those that could have been negotiated
with an unaffiliated party.
    
 
    The Company operates the largest molten sulphur handling system in North
America and has the capacity to transport and terminal over five million long
tons of molten sulphur annually. The Company uses this system both to support
the movement of its own mined and purchased sulphur and as a service that it
markets to recovered sulphur producers and industrial consumers.
 
    Freeport Sulphur is a major purchaser of recovered sulphur, which is sulphur
recovered from the refining of sour natural gas and sour crude oil, purchasing
almost one million tons per year. Approximately 30% of the Company's 1996
sulphur sales were supplied from its recovered sulphur purchases. Substantially
all of the sulphur purchased by the Company, along with the sulphur produced at
the Main Pass and Culberson mines, is sold by the Company to industrial
companies for use in the manufacture of sulphuric acid.
 
   
    The Main Pass operations also contain proved oil reserves from which the
Company produces and sells oil for the Main Pass joint venture. Oil production
averaged approximately 10,700 barrels per day (5,200 barrels net to the Company,
or 7,400 barrels net to the Company on a pro forma basis after the contribution
of the IGL Transferred Businesses) during the year ended December 31, 1996, and
9,400 barrels per day (4,600 barrels net to the Company, or 6,500 barrels net
the Company on a pro forma basis after the contribution of the IGL Transferred
Businesses) during the nine months ended September 30, 1997. As of December 31,
1996, Main Pass was estimated to contain 12.8 million barrels (5.2 million
barrels net to the Company, or 7.4 million barrels net to the Company on a pro
forma basis after the contribution of the IGL Transferred Businesses) of proved
oil reserves. In 1997, such estimates were reduced to 8.2 million barrels (3.2
million barrels net to the Company, or 4.6 million barrels net to the Company on
a pro forma basis after the contribution of the IGL Transferred Businesses) of
proved oil reserves, which are expected to decline substantially in subsequent
years and to be fully depleted by 2001.
    
 
STRATEGY
 
    The Company's strategy is to utilize its extensive production facilities and
its transportation and other logistical capabilities to maintain its leadership
position in the U.S. sulphur market and to capitalize on new marketing
opportunities that are expected to develop from projected increases in global
phosphate fertilizer demand and other uses of sulphur. In addition, the Company
may expand its third party transportation and terminaling services business and
seek opportunities to increase its recovered sulphur marketing activities.
 
    The Company is also evaluating related business opportunities including the
possible construction and operation of sulphur recovery and sulphuric acid
plants for third parties. The Company believes it can market its operational,
technological and marketing expertise to other industrial concerns, and enter
into
 
                                       32
<PAGE>
strategic alliances with enterprises having complementary expertise and shared
growth objectives. The Company also plans to seek opportunities to expand its
business in technologies related to its current Main Pass oil operations such as
sour crude oil processing for others in the Gulf of Mexico region, and the
application of its seawater heating technology to such uses as secondary oil
recovery.
 
    Freeport Sulphur's future sulphur sales volumes and realizations will
continue to depend on the level of demand from the phosphate fertilizer industry
and the availability of competing supplies from recovered sulphur producers.
Accordingly, the Company continually evaluates its sulphur business strategy in
light of competitive factors and the dynamics of the sulphur market, including
the possibility of adjusting overall production levels to match changes in
market fundamentals.
 
    With respect to the Company's oil business, the Company does not currently
intend to pursue oil operations that are not related to Main Pass.
 
SULPHUR BUSINESS
 
    SOURCES AND USES OF SULPHUR
 
    Sulphur is present in many areas of the world and its production is
generally classified into three categories: elemental, pyrites and sulphur in
other forms ("SOF"). Elemental sulphur represents over two-thirds of worldwide
supplies of sulphur in all forms. Its sources include sulphur mined by the
Frasch process from underground deposits and recovered sulphur. The remaining
one-third of worldwide sulphur is in the form of pyrites (metal sulphides) and
SOF, with the most significant source being sulphuric acid recovered as a
by-product from the smelting of non-ferrous metals. In the United States, mined
elemental sulphur is principally found in the caprock that covers salt domes in
the coastal areas of the Gulf of Mexico and in strata-bound deposits in West
Texas. Recovered elemental sulphur is produced from the processing of natural
gas that contains hydrogen sulfide and from the refining of sour (high sulphur
content) crude oil. Recovered sulphur is the largest source of sulphur in the
world, representing approximately 85% of global production of elemental sulphur.
 
    Worldwide, over 56 million long tons of sulphur are consumed annually, of
which over 90% is converted to sulphuric acid. The remainder is used in
elemental form in fertilizer applications, chemical manufacturing and other
applications. While sulphur is essential in almost every segment of the economy,
it is generally used as a processing agent and is seldom apparent in the final
product.
 
    Sulphur is used primarily in the manufacture of phosphate fertilizer, with
over 60% of worldwide sulphur consumption being used for this purpose. Sulphur
is burned to form sulphuric acid, which is then used to convert phosphate rock
to phosphoric acid, the base material for the manufacture of phosphate
fertilizer. Approximately 0.4 of a long ton of sulphur is required to produce
one short ton of diammonium phosphate fertilizer, the principal form of
phosphate fertilizer. Although the Company is highly dependent on the phosphate
fertilizer market, management believes that the overall strength of the
phosphate fertilizer market and the resulting demand for sulphuric acid should
support production at current levels for the immediate future. Industry studies
indicate that world demand for phosphate fertilizer, driven by anticipated
population growth, increases in levels of grain consumption and other factors,
will exceed production capacities in the next several years. This has led to
plans to construct new capacity and feasibility studies evaluating the expansion
of existing capacity and the addition of new capacity for the manufacture of
phosphate fertilizer.
 
    Sulphur is itself an important plant nutrient, along with nitrogen,
phosphorous and potassium. In 1996, 9.0 million tons of sulphur were applied to
soils worldwide through fertilizer application. Sulphur is also a key raw
material in the manufacture of many fungicides and other agricultural chemicals.
The Sulphur Institute estimates the current annual worldwide plant nutrient
sulphur deficit at 8.2 million tons and the outlook is for increasing
deficiencies, thus making the use of sulphur as a fertilizer a developing and
growing market.

    In addition to its agricultural applications, sulphur (usually in the form
of sulphuric acid) is essential to the manufacturing processes of
pharmaceuticals, paper, chemicals, paint, steel, petroleum and other products.
Sulphuric acid is also used in the manufacture of detergents and animal feed.
There is a growing demand for sulphur in the form of sulphuric acid for ore
leaching by the non-ferrous metals industry mainly due to advancements in
solvent extraction-electrowinning technology (SX/EW). This advancement has
allowed the development of oxide ore bodies that previously were not considered
commercially exploitable.
 
    SULPHUR MINE OPERATIONS
 
    OVERVIEW.  Although sulphur is one of the most common elements in the
earth's crust, discoveries of elemental sulphur in quantities that can be mined
economically are rare. The Company is currently mining two such deposits, the
Main Pass mine offshore Louisiana in the Gulf of Mexico and the Culberson mine
in West Texas. The Company's sulphur discovery at Main Pass in 1988 was the
first major sulphur discovery in North America in over 25 years. The Main Pass
and Culberson mines utilize the Frasch mining process, which involves drilling
wells and injecting superheated water into the underground sulphur deposit to
melt solid sulphur, which is then recovered in liquid form. The Company has used
the Frasch process for more than 80 years, and has developed technology using
superheated seawater in the Frasch process, thereby enhancing offshore mining.
 
    THE FRASCH PROCESS.  The sulphur deposits at the Company's Culberson and
Main Pass mines are located approximately 400 and 2,000 feet underground,
respectively. Sulphur production wells are drilled into sulphur bearing
formations by rotary drilling rigs employing a directional drilling technique
that permits drilling from the well platform at angles of up to 85 DEG. from
vertical, allowing sulphur within a radius of more than 3,700 feet to be mined
from a single platform. In addition to production wells, pressure control wells
must also be drilled to recover excess water from the underground formation and
to facilitate water flow. The Frasch process used by the Company permits cost
efficient extraction of sulphur from these underground deposits. Superheated
water and compressed air are forced separately through concentric pipes towards
the sulphur deposit where the heated water liquefies the sulphur and the
compressed air helps lift the molten sulphur to the surface. The Frasch process
was developed in the 1890s and Freeport Sulphur was only the second company to
use this technology. The Company has also developed proprietary technology that
enables it to use seawater in the Frasch process without experiencing the
corrosion and scaling that otherwise would affect the heat exchangers and
pipelines. Frasch mining of sulphur deposits at locations where large quantities
of fresh water are unavailable, such as Main Pass, would not be commercially
viable without these techniques.
 
    Natural gas and water are the two resources essential to the Frasch process.
Natural gas is used to fire steam boilers that produce the superheated water
necessary for sulphur liquefaction. The Company's mine operations currently
consume approximately nine billion cubic feet of natural gas annually. The
Company is dependent on others for the supply of natural gas, but has never
experienced difficulty in obtaining the required supply of natural gas because
it has long-term supply agreements in place with prices tied to market indices.
At Main Pass, where the Company consumes the majority of its natural gas
requirements, gas is supplied by a single supplier, but the Company has access
to a large multiple-supplier pipeline should its primary supplier have
difficulties in delivering its requirements. At the Culberson mine and the Port
Sulphur terminal, natural gas is provided by multiple suppliers. In its Main
Pass operations the Company also supplements its natural gas needs with the gas
that is produced in conjunction with its Main Pass oil operations, which is
provided to the sulphur mining operations in exchange for electricity used by
the oil operations. In the event of a national shortage of natural gas,
curtailment may be imposed by federal authorities and may interfere with the
mining process, but the Company believes that the risk of such curtailment
during the anticipated life of the mines is remote. Moreover, if necessary, the
boilers can also operate on fuel oil. The availability of water for the Main
Pass mine is not a factor for the Company because of its ability to use
seawater.

               DIAGRAMMATIC SKETCH OF A SALT DOME SULPHUR DEPOSIT
 
    THE MINES.  The Main Pass deposit was discovered by the Company in 1988. The
mine currently has the highest production rate of any sulphur mine in the world
and contains the largest known Frasch sulphur reserve in North America. The free
sulphur in the Main Pass deposit exists in the porous limestone that is part of
the caprock covering a salt dome. The Main Pass offshore complex, which is more
than a mile in length, is one of the largest structures of its type in the world
and is the largest in the Gulf of Mexico. The Main Pass mine was designed to
produce an average of 5,500 long tons per day over its life and has two sulphur
storage tanks with a combined capacity of 24,000 long tons. The facility, which
has housing capacity for 240 persons, is located in 210 feet of water and is
designed to withstand hurricane force conditions. In the event of a major storm
in the Gulf, personnel would be evacuated, but the mine is designed to remain in
operation through a communications link to Freeport Sulphur's corporate office
in New Orleans. During the year ended December 31, 1996, sulphur production at
Main Pass averaged approximately 5,350 long tons per day. All Main Pass sulphur
is transported to the Company's terminal in Port Sulphur, Louisiana in 7,500-ton
self-propelled tankers. The Company receives a fee from Homestake for operating
the Main Pass mine and for processing, transporting and marketing Homestake's
share of the Main Pass sulphur. At December 31, 1996, the Main Pass deposit was
estimated to contain proved sulphur reserves totaling 66.2 million long tons
(38.6 million long tons net to the Company, or 55.1 million long tons net to the
Company on a pro forma basis after the contribution of the IGL Transferred
Businesses). Production from the Main Pass mine is subject to a royalty of 12.5%
of net mine revenues that is payable to the U.S. Department of Interior-Minerals
Management Services (the "MMS").
 
   
    The Company began operating the Culberson mine, which is located in West
Texas south of the New Mexico border, in January 1995 after acquiring the mine
from Pennzoil. The Culberson mine's free sulphur is part of a strata-bound
orebody located in the Upper Permian and Salado formations. For the year ended
December 31, 1996, production at the Culberson mine averaged approximately 2,450
long tons per day. A unique feature of the Culberson mine is a continuous water
re-injection system, through which water recovered from pressure control wells
is reheated and re-injected into the production wells. This recycling system
results in significant cost savings. Once mined, the liquid sulphur is stored in
on-site tanks with a combined capacity of 45,000 long tons until it is shipped
to the Company's Galveston terminal by a Company-owned 95-car unit train that
averages 8,400 long tons of liquid sulphur per trip. At December 31, 1996, the
Culberson mine was estimated to contain proved sulphur reserves totaling 14.5
million long tons. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Impairment Assessment of Sulphur Assets."
Production from the Culberson mine is subject to a royalty of 9% of net mine
revenues that is payable to the State of Texas and several private land owners
through a unitization agreement.

<PAGE>
   
    The agreement pursuant to which the Company obtained the Culberson mine
requires the Company to make quarterly payments to Pennzoil, based on a unit
volume payment multiplied by an assumed volume of sulphur, both of which are
determined by the average market price of sulphur during the quarter. The
Company is obligated to make these payments irrespective of whether the
Culberson mine is operational. The payments terminate upon the earlier of
January 2015 or the quarter in which the cumulative assumed volume of production
exceeds 18.6 million long tons. Under this arrangement, the Company paid
Pennzoil $2 million and $1.5 million for fiscal 1996 and the first nine months
of 1997, respectively.
    
 
    The Company has the right, exercisable on January 1, 1999 (the "First Option
Date") and each subsequent third anniversary of the First Option Date, to
terminate its obligation to make further quarterly installment payments in
exchange for a lump sum payment of $65 million less a cumulative inflation
adjustment on the date such right is exercised, but in no event less than $10
million. If the Company does not exercise its right on any option date, Pennzoil
may, within a defined time period after each option date, require the Company to
make a single payment of $10 million in exchange for relinquishing its rights to
receive any further payments under the agreement.
 
    The Company also has rights to sulphur deposits at its Caminada Mine,
located eight miles from Grand Isle in the Gulf of Mexico, which the Company is
not currently mining. The Company is maintaining its lease rights to the
remaining sulphur reserves under a "suspension of production" issued by the MMS.
The Company estimates that the Caminada mine has approximately 1.8 million long
tons of recoverable proved sulphur reserves remaining.

    SULPHUR PURCHASES
 
    The Company is a major purchaser of recovered sulphur in the United States
and management expects its sulphur purchasing program, which is currently
averaging almost one million long tons per year, to increase and become a more
significant component of the Company's business. The Company purchases recovered
sulphur principally from oil refineries located along the lower Mississippi
River and in the Louisiana and Texas Gulf Coast regions, and from gas processing
plants in southern Mississippi.
 
                                       36
<PAGE>
    The Company's recovered sulphur purchase program provides it with a source
of sulphur that is as important as the production from its mines in enabling the
Company to meet its sales contract commitments. Approximately 30% of the
Company's 1996 sulphur sales volume was supplied through recovered sulphur
purchases. The Company believes that its position as a leading sulphur supplier
in the domestic market, coupled with its extensive sulphur handling
capabilities, would allow it to replace any curtailed mine production with
purchased recovered sulphur at price levels that would maintain the Company's
profitability; however there can be no assurance that it will be able to do so.
 
    SULPHUR HANDLING OPERATIONS
 
    OVERVIEW.  The Company operates the largest molten sulphur handling system
in North America and has the capacity to transport and terminal over five
million long tons of molten sulphur annually. The Company uses this system both
to support the movement of its own mined and purchased sulphur, and as a service
that it markets to recovered sulphur producers and industrial consumers. The
Company believes that the integration of the sulphur handling business with its
production, purchasing and marketing operations gives the Company a synergistic
competitive advantage over other suppliers of similar services.
 
    MARINE TRANSPORTATION.  The Company operates two molten sulphur tankers,
each having a capacity of approximately 25,000 tons. The two tankers have the
combined capacity to transport 3.5 million long tons of sulphur per year across
the Gulf of Mexico, which are loaded at the Company's Galveston and Port Sulphur
terminals and delivered to its Tampa terminals. The Company's inland barge
system is capable of transporting over one million tons annually. Each of the
Company's barges has a capacity of approximately 2,500 long tons and serves the
Texas, Louisiana and Mississippi Gulf Coast regions and the lower Mississippi
River. Two 7,500-ton tankers are used to transport sulphur from the Main Pass
mine's offshore production platform and can also be used in Gulf Coast service
to transport sulphur from the Company's terminals to its customers.
 
    LAND TRANSPORTATION.  The Company operates a rail car fleet of more than 500
cars, including a 95-car unit train that transports sulphur from the Culberson
mine to the Galveston terminal for loading onto the Company's tankers for
shipment to its Tampa terminals. The Company also makes other rail movements in
connection with transporting sulphur directly to customers' plants. The Company
also transports approximately 500,000 tons of molten sulphur per year through a
third party trucking service used primarily to serve the Galveston, Texas, lower
Mississippi River and Pensacola, Florida areas.
 
    TERMINALS.  The Company owns and operates five sulphur terminals in the
United States, the largest of which is located at Port Sulphur, Louisiana. The
Port Sulphur facility is a combined liquid storage tank farm and stockpile area
for solid sulphur. Liquid sulphur is stored in steam-heated, insulated tanks
having an aggregate capacity of approximately 110,000 long tons. The solid
storage area can hold approximately 1.3 million long tons of solid sulphur.
Because substantially all of the Company's domestic customers consume sulphur in
liquid form, the Company delivers all of its production in liquid form. This
reduces the need to remelt the sulphur, conserves energy and reduces costs, and
is an environmentally superior handling method. Sulphur can be solidified for
long-term storage to maintain inventory reserves. The Company owns a high
capacity sulphur melter that permits the conversion of solid sulphur into liquid
sulphur to supplement mine production during periods of high demand and to cover
shortfalls in mine production or in recovered sulphur purchases. Sulphur is
transported from Port Sulphur by barge to customers' plants in Louisiana on the
lower Mississippi River or along the Gulf Coast of Texas and Mississippi, or by
tanker to the Company's terminals in Tampa.
 
    The Company's other terminals are located in Tampa and Pensacola, Florida
and Galveston, Texas. There are two Tampa terminals, each of which has a liquid
storage capacity of 90,000 long tons and is supplied with sulphur from Port
Sulphur and Galveston by the Company's sulphur tankers. Each of the Tampa
facilities ships molten sulphur to phosphate fertilizer producers in central
Florida by tank truck. The Pensacola terminal has a storage capacity of 10,000
long tons and is used for the storage, handling and
 
                                       37
<PAGE>
shipping of recovered sulphur purchases or transporting recovered sulphur for
third parties. Molten sulphur is shipped by barge from the Pensacola terminal to
either the Port Sulphur terminal or directly to lower Mississippi River
customers.
 
    The Galveston terminal was acquired from Pennzoil in 1995 and has five
15,000-long ton liquid storage tanks and solid storage capacity of one million
long tons. This terminal receives sulphur from the Company's Culberson mine by
unit train, and recovered sulphur purchases by truck, barge or rail, and then
ships sulphur to local customers by truck or barge or to the Tampa terminals by
tanker. The Galveston terminal also has the ability to load solid sulphur aboard
large oceangoing vessels, giving the Company access to international markets
should market conditions favor sulphur exports.
 
    SULPHUR SALES
 
    Substantially all of the Company's sulphur is sold to the phosphate
fertilizer industry for the manufacture of sulphuric acid, which is used to
produce phosphoric acid, a base chemical used in the production of phosphate
fertilizers. Typically, the phosphate fertilizer industry accounts for
approximately 90% of the Company's total sulphur sales. Freeport Sulphur's
domestic shipments to its five largest customers represented 91% of total
shipments in 1996, 89% in 1995 and 94% in 1994. The majority of the Company's
sulphur supply contracts, with the exception of its contract with IMC-Agrico
discussed below, are for a term of one year or longer and generally call for the
repricing of sulphur on a quarterly or six-month basis.
 
    The Company also processes, transports, and markets Homestake's share of
production at the Main Pass mine for a fee. In addition to supplying the
domestic sulphur market and providing transportation and terminaling services
for others, Freeport Sulphur maintains the capability of marketing sulphur
internationally should market conditions favor export sales.
 
   
    Sales to IMC-Agrico, a manufacturer of phosphate fertilizers and the largest
purchaser of elemental sulphur in the world, represented approximately 65% of
the Company's sulphur sales (or 71% on a pro forma basis after the contribution
of the IGL Transferred Businesses) and 54% of its total revenues (or 57% on a
pro forma basis after the contribution of the IGL Transferred Businesses) during
1996. Pursuant to a Sulphur Supply Agreement, the Company has agreed to supply
and IMC-Agrico has agreed to purchase approximately 75% of IMC-Agrico's annual
sulphur consumption for as long as IMC-Agrico has an operational need for
sulphur. The price per ton for all sulphur delivered under the agreement is
based upon the weighted average market price for sulphur delivered by other
sources to IMC-Agrico's New Wales production plant in central Florida, except
that the Company is entitled to a premium with respect to approximately 40% of
the sulphur that it delivers under the agreement. IMC-Agrico also pays a portion
of the freight costs associated with the delivery of sulphur under the
agreement. Management believes that the terms of the Sulphur Supply Agreement
are no less favorable to the Company than those that could have been negotiated
with an unaffiliated party.
    
 
    Revenues from the Company's sulphur sales depend significantly on production
levels of phosphate fertilizer, the availability of sulphur that is recovered
from high-sulphur oil and natural gas refining and the rate at which stored
surpluses, particularly in Canada, are released into the market and depleted.
Improved phosphate consumption rates, coupled with reduced imports and curtailed
mine production, stabilized sulphur prices beginning in mid-year 1996 and
continuing into the first-half of 1997. However, current prices are
substantially weaker than the high levels of the early 1990's, primarily because
of economic and political changes in Eastern Europe and the former Soviet Union,
which led to the closure of plants consuming in excess of seven million tons of
sulphur per year. To the extent that current United States phosphate fertilizer
production remains strong, sustained sulphur demand is expected to continue;
however, the current level of Canadian sulphur inventories limits the potential
for significant price increases. See "Competition."

OIL AND GAS BUSINESS
 
    OVERVIEW
 
    The Main Pass site also contains oil and natural gas reserves located within
the same caprock reservoir that contains the sulphur reserves. The Company's
estimate of proved recoverable oil reserves at Main Pass at December 31, 1996
was 12.8 million barrels (5.2 million barrels net to the Company or 7.4 million
barrels net to the Company on a pro forma basis after the contribution of the
IGL Transferred Businesses). After 1996 such estimates were reduced to 8.2
million barrels (3.2 million barrels net to the Company, or 4.6 million barrels
net to the Company on a pro forma basis after the contribution of the IGL
Transferred Businesses) due to adjustments made by the Company to the 1996
reserve estimate to account for production during the first half of fiscal 1997
and because certain reserves are no longer believed to be recoverable based on
updated geologic information. No credit was taken in this adjustment for
possible offsetting increases in reserves based on recent production history,
but some offset additions may be possible when Ryder Scott Company performs a
review of the reserves at the end of fiscal 1997. The Main Pass oil reserves are
expected to decline substantially in subsequent years and to be fully depleted
by 2001, and the Company does not intend to pursue oil and gas exploration
operations that are not related to Main Pass.
 
    RESERVES AND ACREAGE
 
    For information relating to estimates of the Company's net interests in
proved oil reserves as of December 31, 1996, and for supplementary information
relating to estimates of discounted future net cash flows from proved oil
reserves, and changes in such estimates, reference is made to the audited
financial statements of the FRP Transferred Businesses, included elsewhere
herein.
 
    At various times, the Company is required to report estimates of oil
reserves to various governmental authorities. The basis for reporting estimates
of reserves to these authorities may not be comparable to the reserves presented
herein because of differences in the times at which such estimates are made and
variances in reserve and other definitions of the particular governmental
authority. Generally, however, the reserves data used for these governmental
reports is computed from the same reserve information base as reported herein.
 
    The Company's interest in Main Pass, which is located in federal waters
offshore Louisiana, constitutes the only oil and gas producing property owned by
Freeport Sulphur. The property consists of 1,125 gross acres and is fully
developed within the meaning of governmental reporting requirements.
 
    The Company possesses a leasehold interest in its Main Pass oil property
that is maintained by production and will remain in effect until production and
drilling and development operations cease. The Company believes that the lease
terms are sufficient to allow for reasonable development of the reserves and
that it has satisfactory title to such property.
 
    PRODUCTION
 
   
    Recoverable hydrocarbons at Main Pass are located in the upper portion of
the same caprock that hosts the sulphur reserves and in an overlying layer of
sand. The limestone caprock reservoir and the overlying sand are in fluid
contact with each other, share a common oil and gas composition and have the
same pressure characteristics. Oil production commenced in the fourth quarter of
1991 with cumulative total production as of September 30, 1997 totaling 34.1
million barrels. Oil production has been enhanced by the injection of
superheated water in the sulphur mining operations, which both lowers oil
viscosity, allowing it to flow more freely, and maintains reservoir pressure,
thereby enhancing recovery. Any associated gas that is produced with the oil is
provided to the sulphur mining operation in exchange for electricity used in the
oil operations. The co-development of the sulphur and oil reserves has yielded
significant operating synergies and efficiencies.
    
 
                                       39
<PAGE>
   
    The purchase agreement pursuant to which the Company obtained the rights to
the Main Pass oil lease obligates the Company under certain circumstances to
make an annual production payment to Chevron U.S.A. Inc. The payment amount is
based on the amount of annual oil production at the Main Pass site and the
amount by which the average annual price of oil exceeds certain specified prices
during the term of the contract. If the average annual price of oil does not
exceed the specified prices, no payment is due. No payments were made for fiscal
1996 or the first nine months of 1997 in connection with this obligation. This
payment obligation will convert to a royalty right on behalf of Chevron upon the
occurrence of certain events that the Company anticipates will occur in the
first half of 1998. Under this royalty right, Chevron will be entitled to
receive 25% of revenues (less transportation costs) of oil and gas production
after the first to occur of (i) cumulative oil production at the Main Pass site
in excess of 36 million barrels or (ii) 20 years from the date of first oil
production (November 6, 1991); provided that this 25% overriding royalty is
limited to 50% of net profit realized on oil production.
    
 
    OIL SALES
 
    Oil prices have historically exhibited, and can be expected to continue to
exhibit, volatility as a result of such factors as conflicts in the Middle East,
actions by the Organization of Petroleum Exporting Countries and changes in
worldwide economic and political conditions. Since the beginning of 1997, oil
prices have fallen by approximately 25%, with some experts speculating that
prices may soften further prior to year end. The oil produced at Main Pass
contains sulphur and is generally heavier than other Gulf Coast crude oils. As a
result, it sells at a discount relative to Gulf Coast crude oils containing less
sulphur and to lighter grade crude oils.
 
    Oil produced at the Main Pass mine is sold to two Gulf Coast refiners with
sales volumes split 72% and 28%. Both sales contracts are for a term of six
months and are priced at market for the oil's grade. AMOCO Production Company is
the Company's largest oil customer, accounting for 74% of oil revenues and 12%
of the Company's total revenues for fiscal 1996.
 
COMPETITION
 
    SULPHUR
 
    In the United States, there are two principal sources of elemental sulphur:
(i) mined sulphur produced by Freeport Sulphur and (ii) recovered sulphur
produced by more than 50 companies at more than 130 refineries and gas treatment
plants. There are four producers of mined sulphur worldwide, of which management
believes Freeport Sulphur is the largest and the only mined sulphur producer
serving the United States market. For 1996, Freeport Sulphur estimates that its
production of sulphur accounted for approximately 27% of domestic, and 6% of
world, elemental sulphur production.
 
    The Company estimates that total domestic sulphur consumption in 1996 was
11.5 million tons, of which domestic Frasch sulphur accounted for approximately
25%, domestic recovered sulphur accounted for approximately 60%, and imported
sulphur, primarily from Canada and Mexico, accounted for approximately 14%. The
remaining 1% of domestic sulphur consumption was attributable to sulphuric acid
produced in metal smelting operations and imported sulphuric acid.

                            ------------------------
 
    Recovered sulphur from domestic and foreign sources is the major source of
competition for Freeport Sulphur. Approximately 90% of the Western Hemisphere's
sulphur inventories currently consist of sulphur recovered from natural gas in
the province of Alberta in western Canada, primarily because United States
recovered sulphur suppliers do not have the ability to store large inventories
of sulphur. During the 1990s world sulphur supply has been in surplus resulting
in a build up of Canadian sulphur inventories. Canadian sulphur inventories were
estimated to be 9.8 million tons at year end 1996 and are expected to increase.
 
    Production of recovered sulphur in the United States has increased at an
average rate of approximately 125,000 tons per year for the last three years,
and totaled approximately 7.6 million tons in 1996. High-sulphur gas processing
capacity in the U.S. is not expected to increase above current levels, but the
sulphur content of crude oil feedstocks to U.S. oil refineries is expected to
continue to increase. Although growth in U.S. recovered sulphur production is
expected to continue, the rate of growth is expected to slow, as the refining
industry is consolidating into a smaller number of large refineries, and it is
estimated that total U.S. refinery processing will not increase substantially.
Technology for recovery of sulphur from coal and oil-burning utility plants is
well advanced and this and other sources of sulphur resulting from air pollution
abatement efforts will have some impact on sulphur supplies. Industry studies
vary in their forecast of the worldwide elemental sulphur balance; however it is
widely accepted that a surplus currently exists and will continue into the
foreseeable future.
 
    Recovered sulphur provides a major and lower cost source of supply for most
sulphur customers. The supply of U.S. recovered sulphur alone, however, cannot
satisfy total domestic demand, and mined sulphur, along with imported recovered
sulphur obtained principally from Canada and Mexico are required to supply the
balance. The principal competitive risk to the Company's ability to mine sulphur
profitably is the potential for decreased domestic demand for sulphur, increased
production from domestic recovered sulphur producers, increases in imported
recovered sulphur, and the rate at which stored sulphur, particularly in Canada,
is released into the market.
 
    OIL
 
    A large number of companies and individuals are engaged in the development
and production of oil. A substantial number of the companies engaged in the
development and production of oil possess financial resources considerably
greater than those of the Company.
 
CUSTOMERS
 
    IMC-Agrico is the Company's single largest sulphur customer, accounting for
approximately 65% of sulphur sales and 54% of total sales for fiscal 1996 (or
71% and 57%, respectively, on a pro forma basis after the contribution of the
IGL Transferred Businesses). The Company's next four largest customers represent
approximately 25% of sulphur sales. These companies represent a mix of
industrial companies and phosphate fertilizer manufacturers.
 
                                       41
<PAGE>
    The oil produced from Main Pass is sold to two Gulf Coast refiners with
sales volumes split 72% and 28%. AMOCO Production Company is the largest
customer, accounting for 12% of the Company's total revenues for fiscal 1996.
 
ENGINEERING, RESEARCH AND DEVELOPMENT
 
    Crescent Technology, Inc. ("Crescent") furnishes certain engineering
consulting, research and development, environmental and safety services to the
Company. Many of Crescent's employees are former employees of the Company, FTX
and other formerly related companies who formed Crescent in 1993 to provide
technical services to such companies and others on an outsourced basis. Crescent
owns and operates laboratory and pilot plant facilities at Belle Chase,
Louisiana, where minerals analysis, metallurgical work and other research and
testing are conducted, which contributes to the Company's technical operations
and commercial activities. Additionally, Crescent maintains engineering
consulting and mine development groups in New Orleans, Louisiana, which provide
the engineering consulting, environmental services and design and construction
supervision activities required to implement new ventures and apply improvements
to the Company's existing operations.
 
OPERATING HAZARDS
 
    The Company's oil and gas and sulphur production activities are subject to
all of the risks normally incident to the development and production of
hydrocarbons and sulphur, including blowouts, cratering, fires and other risks,
any of which could result in serious personal injury or death and substantial
damage to property and the environment. Additionally, its offshore sulphur
mining, oil production and marine transportation operations are subject to
marine perils, including collisions, hurricanes and other adverse weather
conditions. Freeport Sulphur carries insurance for certain of these risks, with
such coverage limits, retentions, deductibles, and other features as management
deems appropriate.
 
REGULATORY MATTERS
 
    The Company's mining, production and exploration activities are subject to
various federal, state and local laws governing exploration, development,
production, exports, taxes, labor standards, occupational health and safety,
toxic substances and other matters. Regulations pertaining to the environment
mandate, among other things, the maintenance of air and water quality standards,
solid and hazardous waste standards, protection of underground sources of
drinking water, and protection and regulation of wetland areas. The Company will
succeed to all licenses, permits or other authorizations obtained or held by FRP
or any of its affiliates insofar as they relate to the sulphur and Main Pass oil
and gas businesses. All licenses, permits and other authorizations currently
required of each existing operation have been obtained or timely applied for.
 
    To comply with these federal, state and local laws, material capital and
operating expenditures on environmental projects, both with respect to
maintaining current operations and initiating new operations, may be required in
the future. The amount of such expenditures cannot be estimated at this time,
but such costs could have an adverse effect on the Company's financial condition
and results of operations. There is also a risk that more stringent laws
affecting the operation of mining companies could be enacted, and although such
regulations would affect the industry as a whole, compliance with such new
regulations could be costly.
 
    Domestic oil operations are subject to extensive state and federal
regulation. Compliance is often burdensome, and failure to comply carries
substantial penalties. The heavy and increasing regulatory burden on the oil
industry increases the cost of doing business and consequently affects
profitability.
 
                                       42
<PAGE>
ENVIRONMENTAL MATTERS
 
    Federal laws and regulations have expanded greatly in recent years with
respect to environmental considerations. The United States Department of
Interior, the U.S. Environmental Protection Agency (the "EPA") and the Coast
Guard administer laws and regulations that impose liability upon the lessee
under a federal lease for the cost of cleanup of pollution damages. A serious
incident of pollution may also result in any one of these agencies requiring
lessees under federal leases to suspend or cease operations in the particular
area. The Company carries insurance against some, but not all, of these risks.
 
    The Company, through its predecessors, has a history of commitment to
environmental responsibility. Since the 1940s, long before the general public
recognized the importance of maintaining environmental quality, the Company has
conducted pre-operational, bioassay, marine ecological and other environmental
surveys to ensure the environmental compatibility of its operations. The
Company's environmental policy commits its operations to compliance with
applicable laws and regulations. The Company has implemented corporate-wide
environmental programs and continues to study methods to reduce discharges and
emissions.
 
    The largest effluent from sulphur mining operations is the pressure control
water recovered from the sulphur-bearing formation. At Main Pass, pressure
control wells remove water from the formation and discharge the water under the
terms of a National Pollutant Discharge Elimination System permit issued by the
EPA. At the Culberson mine, the pressure control water is removed from the
formation and reused in the Frasch mining process. The injection of mine water
at Culberson is authorized by an Underground Injection Control permit issued by
the EPA. Other water discharges at the two mines and five terminals are made
under permits issued by the EPA, state regulatory agencies in the States of
Texas, Louisiana or Florida, or local regulatory authorities. All of these
discharges are in substantial compliance with applicable regulations.
 
    The Company has various other permits with respect to air emissions, solid
waste production and disposal, dredging of bottom sediment and the operation of
port facilities that facilitate its business activities. Agencies that provide
these permits and authorizations include the MMS, the U.S. Coast Guard, the
Louisiana Department of Environmental Quality, the Louisiana Department of
Natural Resources, the Texas Natural Resources Conservation Commission, and the
Florida Department of Environmental Protection. The Company believes it is in
compliance in all material respects with the terms and conditions of these
permits and does not anticipate any significant new costs to obtain new permits
or to maintain compliance with existing permits.
 
    In connection with the Contribution, the Company has assumed responsibility
for environmental liabilities associated with the prior conduct of the
Transferred Businesses, including reclamation responsibilities at three
previously producing sulphur mines. Sulphur production was suspended at the
Company's Caminada offshore sulphur mine in 1994, and the Company will be
required to salvage the mining facilities once the remaining reserves are
produced or it becomes certain that such reserves will not be economically
recoverable. The Company's salvage expense will be shared on a 50/50 basis with
Exxon Corporation, and a reserve has been accrued for the estimated expense.
 
    The Company's Grande Ecaille mine, which was depleted in 1978, was salvaged
in accordance with applicable regulations at the time of closure. Although the
Company has no legal obligation to do so, it has undertaken to reclaim wellheads
and other materials, none of which are classified as hazardous, that are being
exposed through coastal erosion, and it is anticipated that these reclamation
activities will continue for several more years. Additional expenditures may be
required from time to time if erosion continues, although the Company does not
expect such expenditures to be material. Additional expenditures may be
necessary in the future to remove building foundations should the Company decide
it is in the best interest of the Company to do so.
 
                                       43
<PAGE>
    Reclamation of the Company's two producing sulphur mines, Main Pass and
Culberson, will be required upon the closure of those facilities, and a reserve
account is being accumulated to cover this expense. The Company has also closed
nine other sulphur mines, all of which have been reclaimed in accordance with
applicable regulations and customary industry practices.
 
    In September 1997 the Company completed the salvage of its Grand Isle mine
in the Gulf of Mexico, which was depleted in 1991, by converting it into an
artificial reef for the enhancement of marine life. The reef was constructed at
the request of the State of Louisiana as part of its "Rigs-to-Reefs" program
through which the State and private industry are cooperating to provide useful
marine habitats using offshore structures that are no longer needed for
commercial activities. The Grand Isle reef is the first in shallow water and is
the largest in the Gulf of Mexico. The reef was donated to the State of
Louisiana, which has assumed all responsibility for its upkeep, although the
Company will retain responsibility for any environmental liabilities that may
arise from previous mining activities with respect to this site.
 
    Although the Company believes that its prior reclamation activities were
carried out in compliance with then applicable laws and regulations and that it
is accruing adequate reserves to cover future reclamation costs, no assurance
can be given that the Company will not incur materially greater reclamation
costs than those anticipated.
 
EMPLOYEES
 
   
    As of September 30, 1997, Freeport Sulphur had 426 active employees. There
are 402 employees working at the Company's mine sites and terminals, and 24
employees located at its New Orleans headquarters. None of the employees of
Freeport Sulphur is represented by any union or covered by any collective
bargaining agreement. The Company believes its employee relations are
satisfactory.
    
 
    The Company also uses contract personnel to perform many of the technical
tasks customarily conducted by Company employees at its Main Pass mine, which
minimizes development costs and allows the Company to use its management staff
to direct the efforts of both the sulphur mine and oil operations. Freeport
Sulphur also receives financial, legal and administrative and other related
services through an administrative services agreement with FMS. See "Risk
Factors--Dependence on Management and Administrative Services."
 
LEGAL PROCEEDINGS
 
    The Company is involved from time to time in various legal proceedings of a
character normally incident to its businesses. The Company believes that its
potential liability in any such pending or threatened proceedings will not have
a material adverse effect on the financial condition or results of operations of
the Company. The Company, through FMS, maintains liability insurance to cover
some, but not all, potential liabilities normally incident to the ordinary
course of its businesses with such coverage limits as management deems prudent.

DIRECTOR COMPENSATION
 
    Each Director who is not an employee of the Company will be paid an annual
director's fee of $15,000 and an attendance fee of $500 for each committee
meeting attended. All Directors will be paid an attendance fee of $1,000 for
each board meeting attended. Each Director will be reimbursed for reasonable
out-of-pocket expenses incurred in attending board and committee meetings. Each
Director who is not an employee of the Company will also be eligible to receive
options to purchase shares of Common Stock under the terms of the Director Plan
described below.
 
COMMITTEES OF THE BOARD OF DIRECTORS
 
    The Company's Board of Directors has established an Audit Committee and a
Corporate Personnel Committee (the "Compensation Committee"). The Audit
Committee is responsible for reviewing the Company's financial statements and
annual audit and meeting with the Company's independent public accountants to
review the Company's internal controls and financial management practices. The
members of the Audit Committee are Messrs. Brown, Clark and Rankin.
 
    The Compensation Committee is responsible for recommending to the Board of
Directors compensation for the Company's key employees, including its Executive
Officers, and administering the Company's incentive plans and performing such
other similar functions as may be assigned by the Board of Directors. The
members of the Compensation Committee are Messrs. Brown and Clark.
 
EXECUTIVE COMPENSATION
 
    The Company was not incorporated until August 26, 1997, and therefore did
not have any Executive Officers or employees during the year ended December 31,
1996. The future compensation and employment arrangements of the Company's
Executive Officers and employees will be determined by the Board of Directors
and the Compensation Committee.
 
    The services of the Executive Officers who are not employed by the Company
will be provided to the Company by FMS under a management services agreement.
The Company will reimburse FMS at FMS' cost, including allocated overhead, for
such services. Such Executive Officers will be compensated exclusively by FMS
for their services to the Company. Those Executive Officers who are also
employees of FMS are eligible to participate in certain FMS employee benefit
plans and programs. The total costs to FMS for such Executive Officers,
including the costs borne by FMS with respect to such plans and programs, will
be allocated to the Company, to the extent practicable, in proportion to the
time spent by such Executive Officers on Company affairs. No other payment will
be made by the Company to FMS for providing such compensation and benefit plans
and programs to such Executive Officers.
 
                                       46
<PAGE>
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    The members of the Company's Compensation Committee are Messrs. Brown and
Clark, neither of whom has ever been an officer or employee of the Company, nor
has or has had any other significant relationship with the Company. No Executive
Officer of the Company serves as a director or member of the compensation
committee of another entity, one of whose executive officers will serve as a
Director or on the Compensation Committee of the Company.
 
THE EMPLOYEE BENEFITS AGREEMENT
 
    The Company, FTX and FRP have entered into the Employee Benefits Agreement
to provide for the transfer of assets and liabilities pertaining to certain
employee benefit plans maintained by FTX for the benefit of FTX employees who
have in the past provided services to FRP in connection with the FRP Transferred
Businesses and to provide for the compensation and benefits of those employees
who will become employees of the Company (the "Transferred Employees"). In
accordance with the terms of the Employee Benefits Agreement, the Company will
sponsor qualified and non-qualified defined contribution and defined benefit
pension plans that initially will have substantially the same provisions as the
FTX pension plans and will provide credit for prior FTX service. All liabilities
under the FTX pension plans with regard to the Transferred Employees will be
transferred to the Company's plans. Assets sufficient to fund the transferred
qualified plan liabilities will be transferred from the FTX plans to the
comparable Company plans, and assets sufficient to fund the transferred
non-qualified plan liabilities will be transferred from FTX to the Company.
 
    The Company will establish new welfare benefit plans, such as medical,
dental, life insurance, disability and sick leave plans, which will credit
Transferred Employees with prior service at FTX and will credit items such as
deductibles, limits and usage of and by Transferred Employees under similar FTX
plans. FTX will pay the Company an actuarially-determined amount to cover the
costs of post-retirement medical benefits for Transferred Employees. The Company
will assume responsibility for all claims made after the Merger by Transferred
Employees on sickness, disability or other leaves of absence. FTX will retain
liability for retiree medical benefits for employees who retired prior to the
Merger, but the Company has agreed to reimburse FTX quarterly for a portion of
those expenses for former employees who provided services primarily for the
Transferred Businesses. In addition, the Company will reimburse FTX for claims
and premiums related to COBRA coverage for certain employees who lose medical
coverage as a result of the Merger and related transactions.
 
    Pursuant to the Employee Benefits Agreement, each outstanding stock option,
stock appreciation right, and stock incentive unit relating to FTX Common Stock
that has been granted under an FTX stock option or stock incentive plan and that
is held by any person other than an employee of IGL or the IMC-Agrico joint
venture (collectively, the "FTX Awards") will be converted into an adjusted FTX
stock option, stock appreciation right, or stock incentive unit, respectively
(an "Adjusted FTX Award"), and a new non-qualified option to purchase Common
Stock (a "Company Option") under the Company's Adjusted Stock Award Plan
described below. Thus, after the FTX Stockholder Distribution, each holder of an
FTX Award will hold an Adjusted FTX Award and a Company Option. The number of
shares of FTX Common Stock subject to the Adjusted FTX Award will be the same as
the number of shares of FTX Common Stock subject to the related FTX Award, and
the number of shares of Common Stock subject to the Company Option will be the
number of shares of Common Stock that a holder of record of the number of shares
of FTX Common Stock subject to the related FTX Award would be eligible to
receive in the FTX Stockholder Distribution.
 
    If the FTX Award that is converted contains a "tax-offset" payment right
feature, the Company Option derived from such FTX Award will relate to a number
of shares of Common Stock determined as described above multiplied by a factor
of 1.6556. No Company Option will contain a "tax-offset" payment
 
                                       47
<PAGE>
right feature. Each Company Option will, however, have in-tandem "limited
rights" equal in number to the number of shares of Common Stock subject to such
Company Option.
 
    The exercise price of each FTX Award will be allocated between the Adjusted
FTX Award and the Company Option based on the relative fair market values of FTX
Common Stock and Common Stock at the time of the Merger. Each Company Option and
each Adjusted FTX Award will have the same exercisability terms, remaining
duration and change of control provisions as the FTX Award from which it was
derived.
 
    In connection with the Merger, each outstanding Adjusted FTX Award, whether
a stock option, stock appreciation right or stock incentive unit, will, in
effect, be converted into an IGL stock option, stock appreciation right or stock
incentive unit, respectively.
 
    In accordance with the terms of the Employee Benefits Agreement, FTX will
calculate, as of the date of the FTX Stockholder Distribution, its liability
under various non-qualified incentive plans in respect of the deferred
compensation of the Transferred Employees. In consideration of a cash payment by
FTX to the Company in an amount equal to such accrued liability, the Company
will assume such liability in respect of the Transferred Employees. Similarly,
FTX shall determine the total amount of cash bonus payments that it would have
made to the Transferred Employees as a group under non-qualified incentive plans
for 1997, and, in consideration of a cash payment by FTX to the Company in an
amount equal thereto, the Company will assume the payment of such amounts to the
Transferred Employees as soon as feasible after 1997 in accordance with
procedures it may later establish for payment of cash incentives to its
employees.
 
STOCK OPTION PLANS
 
   
    COMPANY ADJUSTED STOCK AWARD PLAN
    
 
   
    The Company has adopted the Freeport-McMoRan Sulphur Inc. Adjusted Stock
Award Plan (the "Company Adjusted Stock Award Plan"). The purpose of the Company
Adjusted Stock Award Plan is to provide for the issuance of the Company Options
as described under "The Employee Benefits Agreement" above. No other awards will
be made under the Company Adjusted Stock Award Plan.
    
 
    The maximum number of shares of Common Stock in respect of which stock
options may be granted under the Company Adjusted Stock Award Plan is expected
to be approximately 450,000, and will be determined in accordance with the
conversion procedures described under "The Employee Benefits Agreement" above.
No individual will be granted awards under the Company Adjusted Stock Award Plan
with respect to more than 200,000 shares of Common Stock. The shares of Common
Stock to be delivered under the Company Adjusted Stock Award Plan will be made
available from the authorized but unissued shares of Common Stock or from
treasury shares.
 
    The Company Adjusted Stock Award Plan will be administered by the
Compensation Committee, upon which no Director who is an officer of the Company
may serve. Current and former employees, officers and directors of FTX who hold
FTX Awards at the Effective Time of the Merger are eligible to receive stock
options under the Company Adjusted Stock Award Plan. It is estimated that
approximately 180 persons will receive stock options under the Company Adjusted
Stock Award Plan pursuant to the conversion of FTX Awards described above.
 
    Stock options granted under the Company Adjusted Stock Award Plan will have
the terms described under "The Employee Benefits Agreement" above. If the
Compensation Committee determines that any dividend or other distribution
(whether in the form of cash, securities, or other property), recapitalization,
stock split, reverse stock split, reorganization, merger, consolidation,
split-up, spin-off, combination, repurchase or exchange of shares, issuance of
warrants or other rights to purchase securities of the Company, or other similar
corporate transaction or event affects the Common Stock such that an adjustment
is appropriate to prevent dilution or enlargement of the benefits intended under
the Company
 
                                       48
<PAGE>
Adjusted Stock Award Plan, then the Compensation Committee has discretion to (i)
adjust the number and type of shares (or other securities or property) with
respect to which options may be granted, (ii) make equitable adjustments in the
number and kind of shares (or other securities or property) subject to
outstanding stock options and the respective exercise prices thereof and (iii)
if appropriate, provide for the payment of cash to a participant.
 
    The Company Adjusted Stock Award Plan may be amended at any time by the
Board of Directors, except that stockholder approval will be required if
determined by the Compensation Committee to be necessary or advisable in order
to comply with any tax or regulatory requirement.
 
    The federal income tax consequences of the stock options are described below
under "--Federal Income Tax Consequences."
 
    The following table sets forth information with respect to the stock options
anticipated to be granted under the Company Adjusted Stock Award Plan, to (i)
each of the Executive Officers, (ii) all Executive Officers as a group, (iii)
each of the Directors who is not an Executive Officer, (iv) all Directors who
are not Executive Officers as a group and (v) all employees of the Company,
including all officers who are not Executive Officers as a group, based on the
number of FTX Awards held by each of them as of October 31, 1997 and assuming
that each share of FTX Common Stock converted in the Merger will entitle the
holder to receive 0.2123 of a share of Common Stock. No associate of any
Director or Executive Officer is anticipated to be eligible to participate in
the Company Adjusted Stock Award Plan. Other than the persons identified in the
following table, no person is anticipated to receive more than 5% of the awards
anticipated to be granted under the Company Adjusted Stock Award Plan. Each
option will be immediately exercisable in full and will have a term equal to the
remaining term of the FTX Award. Each stock option is granted in conjunction
with a limited right, the terms of which are as described under "--1997 Stock
Option Plan" below.

    1997 STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS
    
 
    The Company has adopted the Freeport-McMoran Sulphur Inc. 1997 Stock Option
Plan for Non-Employee Directors (the "Director Plan"). The purpose of the
Director Plan is to align more closely the interests of the Company's
non-employee Directors with those of the Company's stockholders by providing
 
                                       49
<PAGE>
for the automatic grant of stock options to such Directors in accordance with
the terms of the Director Plan.
 
    The maximum number of shares of Common Stock in respect of which options may
be granted under the Director Plan is 75,000. The shares of Common Stock to be
delivered under the Director Plan will be made available from the authorized but
unissued shares of Common Stock or from treasury shares.
 
    Except for determinations with respect to the transferability of options,
which will be made by the Compensation Committee, the Director Plan will be
administered by the Board of Directors.
 
    All Directors who are not employees of the Company or a subsidiary will be
"Eligible Directors" under the Director Plan. There will initially be three
Eligible Directors. Each Eligible Director will be granted an option to purchase
5,000 shares of Common Stock upon the Distributions and an option to purchase
1,000 shares on May 1 of each year that the Director Plan is in effect.
 
    Options granted under the Director Plan will be non-qualified options. The
exercise price of options granted under the Director Plan will be 100% of the
fair market value of the underlying shares of Common Stock on the date of grant.
Each option becomes exercisable in 25% annual increments beginning on the first
anniversary of the date of grant, and will have a term of 10 years. Upon
termination of Board service, except in the case of death or retirement, an
option may be exercised, to the extent exercisable at the time of termination of
Board service, for a period of three months, but no later than the expiration
date of the option. Upon death or retirement from service as a Director, a
Director's options that were exercisable on the date of death or retirement or
could have become exercisable within one year after such date will remain
exercisable until the earlier of (i) in the case of death, the first anniversary
of the date of death, or in the case of retirement, the third anniversary of the
date of such retirement or (ii) the expiration date of the option. An option
will become exercisable in full upon a change of control of the Company, as
defined in the Director Plan.
 
    The option exercise price may be satisfied in cash or by delivering shares
of Common Stock owned by the optionee.
 
    If the Board determines that any dividend or other distribution (whether in
the form of cash, securities, or other property), recapitalization, stock split,
reverse stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase or exchange of shares or other securities of the
Company, issuance of warrants or other rights to purchase securities of the
Company, or other similar corporate transaction or event affects the Common
Stock such that an adjustment is appropriate to prevent dilution or enlargement
of the benefits intended under the Director Plan, then the Board has discretion
to (i) adjust the number and type of shares (or other securities or property)
with respect to which options may be granted, (ii) make equitable adjustment in
the number and kind of shares (or other securities or property) subject to
outstanding stock options and the respective exercise prices thereof and (iii)
if appropriate, provide for the payment of cash to a participant. In the event
the Company is merged or consolidated into or with another corporation in a
transaction in which the Company is not the survivor, or in the event that
substantially all of the Company's assets are sold to another entity not
affiliated with the Company, any holder of an option, whether or not then
exercisable, will be entitled to receive (unless the Company takes such
alternative action as may be necessary to preserve the economic benefit of the
option for the optionee) on the effective date of any such transaction, in
cancellation of such option, an amount in cash equal to the excess, if any, of
the fair market value on the effective date of any such transaction of the
shares underlying such option over the aggregate exercise price thereof.
 
    The Director Plan may be amended or terminated at any time by the Board of
Directors, except that no amendment will be made without stockholder approval if
stockholder approval is deemed necessary to comply with regulatory requirements.
 
    The federal income tax consequences of the stock options are described below
under "--Federal Income Tax Consequences."

    1997 STOCK OPTION PLAN
    
 
    The Company has adopted the Freeport-McMoRan Sulphur Inc. 1997 Stock Option
Plan (the "Stock Plan"). The purpose of the Stock Plan is to motivate and reward
key personnel by giving them a proprietary interest in the Company's success.
 
    Awards under the Stock Plan will be made by the Compensation Committee. The
Compensation Committee has full power and authority to designate participants,
set the terms of awards and to make any determinations necessary or desirable
for the administration of the Plan.
 
    Those persons eligible to participate in the Stock Plan are: (a) officers
and key employees of the Company and its existing or future subsidiaries, (b)
officers and employees of any entity with which the Company has contracted to
receive executive, management or legal services and who provide services to the
Company or a subsidiary under such arrangement, (c) any consultant or advisor to
the Company, a subsidiary or an entity with which the Company has contracted to
receive executive, management or legal services and who provides services to the
Company or a subsidiary under such arrangement and (d) any person who has agreed
in writing to become eligible to participate within 30 days. A subsidiary is
defined as (i) a corporation or other entity in which the Company possesses
directly or indirectly equity interests representing at least 50% of the voting
power or 50% of the total value of all classes of equity interests of such
corporation or other entity and (ii) any other entity in which the Company has a
direct or indirect economic interest that is designated as a subsidiary by the
Compensation Committee. The Compensation Committee may delegate to certain
Executive Officers of the Company the power to make awards to eligible persons
who are not Executive Officers or Directors, subject to limitations to be
established by the Compensation Committee. It is anticipated that the
Compensation Committee's determinations of which eligible individuals will be
granted awards and the terms thereof will be based on each individual's present
and potential contribution to the success of the Company and its subsidiaries.
It is estimated that approximately fifty persons will be granted awards under
the Stock Plan.
 
    The maximum number of shares of Common Stock with respect to which awards
payable in shares of Common Stock may be granted under the Stock Plan is
1,000,000, plus, to the extent authorized by the Board, the number of shares
reacquired by the Company in the open market or in private transactions for an
aggregate price no greater than the cash proceeds received by the Company from
the exercise of Stock Plan options. Grants of stock appreciation rights, limited
rights and other stock-based awards not granted in tandem with options and
payable only in cash may relate to no more than 1,000,000 shares. No individual
may receive in any year awards under the Stock Plan that relate to more than
200,000 shares of Common Stock. Shares subject to awards that are forfeited or
canceled will again be available for award. In addition, to the extent that
shares are delivered to pay the exercise price of options or are delivered or
withheld by the Company in payment of the withholding taxes relating to an award
under the Stock Plan, the number of shares withheld or delivered will again be
available for grant under the Stock Plan. The shares to be delivered under the
Stock Plan will be made available from the authorized but unissued shares of
Common Stock or from treasury shares.
 
    Stock options, stock appreciation rights, limited rights, and other
stock-based awards may be granted under the Stock Plan in the discretion of the
Compensation Committee. Options granted under the Stock Plan may be either
non-qualified or incentive stock options. Only employees of the Company and its
subsidiaries will be eligible to receive incentive stock options. Stock
appreciation rights and limited rights may be granted in conjunction with or
unrelated to other awards and, if in conjunction with an outstanding option or
other award, may be granted at the time of such award or thereafter, at the
exercise price of such other award. The Compensation Committee has discretion to
fix the exercise price of such options at a price not less than 100% of the fair
market value of the underlying Common Stock at the time of grant thereof (or at
the time of grant of the related award in the case of a stock appreciation right
or limited right granted in conjunction with an outstanding award), except that
this limitation on the Compensation Committee's discretion does not apply in the
case of awards granted in substitution for outstanding awards previously granted
by an acquired company or a company with which the Company combines. The
 
                                       51
<PAGE>
Compensation Committee has broad discretion as to the terms and conditions upon
which options and stock appreciation rights are exercisable, but under no
circumstances will an option, a stock appreciation right or a limited right have
a term exceeding 10 years.
 
    The option exercise price may be satisfied in cash, or in the discretion of
the Compensation Committee, by exchanging Common Stock owned by the optionee or
by a combination of cash and Common Stock. The ability to pay the option
exercise price in Common Stock would permit an optionee to engage in a series of
successive stock-for-stock exercises of an option (sometimes referred to as
"pyramiding") and thereby fully exercise an option with little or no cash
investment; however, it is expected that the Compensation Committee's policy
will be to require any stock tendered in payment of the exercise price to be in
certificated form and to have been held by the exercising optionee for such time
as is sufficient to avoid any adverse accounting consequences to the Company
resulting from the permitting of stock-for-stock exercises.
 
    Upon the exercise of a stock appreciation right with respect to Common
Stock, a participant would be entitled to receive, for each such share subject
to the right, the excess of the fair market value of such shares on the date of
exercise over the exercise price of such right. The Compensation Committee has
the authority to determine whether the value of a stock appreciation right is
paid in cash or Common Stock or a combination thereof.
 
    Limited rights generally are exercisable only during a period beginning not
earlier than one day and ending not later than 90 days after the expiration date
of any tender offer, exchange offer or similar transaction that results in any
person or group becoming the beneficial owner of more than 40% of all classes
and series of the Company's stock outstanding, taken as a whole that have voting
rights with respect to the election of directors of the Company (not including
shares of preferred stock which may be issued in the future that have the right
to elect directors only if the Company fails to pay dividends). Upon the
exercise of a limited right granted under the Stock Plan, a participant would be
entitled to receive, for each share of Common Stock subject to such right, the
excess, if any, of the highest price paid in or in connection with such
transaction over the grant price of the limited right.
 
    The Stock Plan also authorizes the Compensation Committee to grant to
participants awards of Common Stock and other awards that are denominated in,
payable in, valued in whole or in part by reference to, or are otherwise based
on the value of, Common Stock ("Other Stock-Based Awards"). The Compensation
Committee has discretion to determine the participants to whom Other Stock-Based
Awards are to be made, the times at which such awards are to be made, the size
of such awards, the form of payment, and all other conditions of such awards,
including any restrictions, deferral periods or performance requirements. The
terms of the Other Stock-Based Awards will be subject to such rules and
regulations as the Compensation Committee determines.
 
    Any award under the Stock Plan may provide that the participant has the
right to receive currently or on a deferred basis dividends or dividend
equivalents or other cash payments in addition to or in lieu of such awards, all
as the Compensation Committee determines.
 
    If the Compensation Committee determines that any dividend or other
distribution (whether in the form of cash, securities or other property),
recapitalization, stock split, reverse stock split reorganization, merger,
consolidation, split-up, spin-off, combination, repurchase or exchange of shares
or other securities of the Company, issuance of warrants or other rights to
purchase securities of the Company, or other similar corporate transaction or
event affects the Common Stock such that an adjustment is appropriate to prevent
dilution or enlargement of the benefits intended under the Stock Plan, then the
Compensation Committee has discretion to (i) adjust the number and kind of
shares that may be the subject of future awards under the Stock Plan, (ii) make
equitable adjustment in the number and kind of shares (or other securities or
property) subject to outstanding awards and the respective grant or exercise
prices thereof and (iii) if appropriate, provide for the payment of cash to a
participant.
 
                                       52
<PAGE>
    The Stock Plan may be amended or terminated at any time by the Board of
Directors, except that no amendment may be made without stockholder approval if
such approval is determined by the Compensation Committee to be necessary or
advisable in order to comply with any tax or regulatory requirement, including
any approval requirement that is necessary to qualify awards as
"performance-based" compensation under Section 162(m) of the Code.
 
    The grant of awards under the Stock Plan is entirely in the discretion of
the Compensation Committee. The Compensation Committee has not yet made a
determination as to the awards to be granted under the Stock Plan.
 
   
    FEDERAL INCOME TAX CONSEQUENCES
    
 
    An optionee will not recognize any income for federal income tax purposes
upon the grant of a non-qualified stock option, nor will the Company normally
realize any deduction for federal income tax purposes at the time of grant. When
an optionee exercises a non-qualified option, the difference between the
exercise price and any higher fair market value of the Common Stock on the date
of exercise will be ordinary income to the optionee (subject to withholding) and
will generally be allowed as a deduction at that time for federal income tax
purposes to the Company.
 
    Any gain or loss realized by an optionee on disposition of the Common Stock
acquired upon exercise of a non-qualified option will generally be capital gain
or loss to the optionee, long-term or short-term depending on the holding
period, and will not result in any additional federal income tax consequences to
the Company. The optionee's basis in the Common Stock for determining gain or
loss on the disposition will be the fair market value of the Common Stock
determined generally at the time of exercise.
 
    When an optionee exercises an incentive stock option while employed by the
Company or a subsidiary or within three months (one year for disability) after
termination of employment by reason of retirement or death, no ordinary income
will be recognized by the optionee at that time, but the excess (if any) of the
fair market value of the Common Stock acquired upon such exercise over the
option price will be an adjustment to taxable income for purposes of the federal
alternative minimum tax applicable to individuals. If the Common Stock acquired
upon exercise of the incentive stock option is not disposed of prior to the
expiration of one year after the date of acquisition and two years after the
date of grant of the option, the excess (if any) of the sale proceeds over the
aggregate option exercise price of such Common Stock will be long-term capital
gain, but the Company will not be entitled to any tax deduction with respect to
such gain. Generally, if the Common Stock is disposed of prior to the expiration
of such periods (a "Disqualifying Disposition"), the excess of the fair market
value of such Common Stock at the time of exercise over the aggregate option
exercise price (but not more than the gain on the disposition if the disposition
is a transaction on which a loss, if realized, would be recognized) will be
ordinary income at the time of such Disqualifying Disposition (and the Company
will generally be entitled to a federal income tax deduction in a like amount).
Any gain realized by the optionee as the result of a Disqualifying Disposition
that exceeds the amount treated as ordinary income will be capital in nature,
long-term or short-term depending on the holding period. If an incentive stock
option is exercised more than three months (one year for disability) after
termination of employment, the federal income tax consequences are the same as
described above for non-qualified stock options.
 
    If the exercise price of an option is paid by the surrender of previously
owned shares, the basis of the previously owned shares carries over to the
shares received in replacement therefor. If the option is a non-qualified
option, the income recognized on exercise is added to the basis. If the option
is an incentive stock option, the optionee will recognize gain if the shares
surrendered were acquired through the exercise of an incentive stock option and
have not been held for the applicable holding period. This gain will be added to
the basis of the shares received in replacement of the previously owned shares.
 
    Awards that are granted, accelerated or enhanced upon the occurrence of a
change of control may give rise, in whole or in part, to excess parachute
payments within the meaning of Section 280G of the Code to the extent that such
payments, when aggregated with other payments subject to Section 280G,
 
                                       53
<PAGE>
exceed the limitations contained therein. Such excess parachute payments will be
nondeductible to the Company and subject the recipient of the payments to a 20%
excise tax.
 
    If permitted by the Compensation Committee, at any time that a participant
is required to pay to the Company the amount required to be withheld under
applicable tax laws in connection with the exercise of a stock option or the
issuance of Common Stock, the participant may elect to have the Company withhold
from the shares that the participant would otherwise receive shares of Common
Stock having a value equal to the amount to be withheld. This election must be
made prior to the date on which the amount of tax to be withheld is determined.
 
    The foregoing discussion summarizes the federal income tax consequences of
stock options that may be granted under the Company Adjusted Stock Award Plan,
the Directors Plan and the Stock Plan, based on current provisions of the Code,
which are subject to change. This summary does not cover any foreign, state or
local tax consequences or participation in such plans.
 
   
    RETIREMENT BENEFIT PROGRAM
    
 
    The Company has adopted a retirement benefit program. Under the program,
each participant, including Executive Officers, is entitled to benefits based
upon the sum of his starting account balance, annual benefit credits and annual
interest credits allocated to his "account." The starting account balance is
equal to the value of the participant's accrued benefit under FTX's plan at the
time of the FTX Stockholder Distribution. The annual benefit credit consists of
two parts: (1) 4% of the participant's earnings for the year in excess of the
social security wage base for the year; and (2) a percentage of the
participant's total earnings for the year. The percentage of total earnings is
determined as follows:
 
    - 15%, if as of January 1, 1997, the participant's age plus service totaled
      65 or more, he was at least 50 years old and had at least 10 years of
      service;
 
    - 10%, if as of January 1, 1997, the participant's age plus service totaled
      55 or more, he had at least 10 years of service, and he did not meet the
      requirements for a 15% allocation;
 
    - 7%, if as of January 1, 1997, the participant's age plus service totaled
      45 or more, he had at least 5 years of service, and he did not meet the
      requirements for a greater allocation;
 
    - 4%, if the participant did not meet the requirements for a greater
      allocation.
 
    The annual interest credit is equal to the account balance at the end of the
prior year multiplied by the annual yield on 10-year U.S. Treasury securities on
the last day of the preceding year. Interest credits stop at the end of the year
in which the participant reaches age 60. Upon retirement a participant's account
balance is payable either in a lump sum or an annuity, as selected by the
participant. A participant's "earnings" are comprised of annual base salary,
plus a percentage of certain bonuses, which percentage is the lesser of 50% or
the percentage of the bonus not deferred. Years of service include not only
years with the Company but also any years with FTX and FRP and any of their
predecessors.
 
    Benefits payable to a participant under the FTX retirement benefit program
under which participants in the Company's plan have previously participated were
at one time determined primarily by such individual's final average compensation
and years of service. The Company's retirement benefit program does not
incorporate this design. However, if a participant's age plus service equaled 65
or more as of January 1, 1997, and as of that date the participant had both
attained age 50 and had at least 10 years of service, the participant is
"grandfathered" into a benefit of no less than the benefit under the former FTX
retirement benefit formula based on years of service and final average earnings.
 
    Currently no Executive Officers are participating in this program.
 
                                       54
<PAGE>
                             PRINCIPAL STOCKHOLDERS
 
    None of the individuals serving as a Director or Executive Officer of the
Company currently owns any shares of Common Stock, all of which currently are
owned by FRP. The Directors and Executive Officers will receive shares of Common
Stock in respect of shares of FTX Common Stock and FRP units of partnership
interest held by them at the time of the Distributions. In addition, the Company
has agreed to issue to the Directors and Executive Officers and other holders of
stock options, stock appreciation rights and other similar stock-based awards
granted under certain FTX benefit plans options to purchase Common Stock under
the Company Adjusted Stock Award Plan described above.
 
    The following table sets forth certain information regarding the number of
shares of Common Stock expected to be beneficially owned by (i) each of the
Directors and Executive Officers; (ii) all Directors and Executive Officers as a
group and (iii) each person expected to own more than 5% of the outstanding
Common Stock, immediately after the Distributions, determined in accordance with
Rule 13d-3 under the Securities Exchange Act of 1934 (the "1934 Act"). In
calculating the number of shares, it is assumed that each share of FTX Common
Stock converted in the Merger will entitle the holder to receive 0.2123 of a
share of Common Stock. Except as otherwise noted, each of the individuals will
have sole voting and investment power with respect to such Common Stock.

                              CERTAIN TRANSACTIONS
 
    FRP and the Company are parties to the Distribution Agreement and the
Employee Benefits Agreement, which are discussed elsewhere in this Prospectus.
See "The Merger and the Distributions" and "Management--Employee Benefits
Agreement." At the time these agreements were negotiated and executed, the
Company was a wholly-owned subsidiary of FRP.
 
    Prior to 1996, the Company received certain management and administrative
services from FTX. Beginning in 1996, FMS began providing these services under a
Management Services Agreement that was negotiated and executed when FMS was an
affiliate of FTX and FRP, and the Company was a wholly-owned subsidiary of FRP.
Subsequent to the Distributions, FMS will be 25% owned by the Company. Pursuant
to these arrangements, the Company paid FTX $8.8 million and $15.9 million
(including $7.0 million for stock appreciation right costs) for fiscal 1994 and
1995, respectively, and in 1996 paid FMS and FTX $6.7 million and $2.0 million,
respectively.
 
    IMC-Agrico and the Company are parties to the Sulphur Supply Agreement. At
the time this agreement was negotiated and executed, the Company was a
wholly-owned subsidiary of FRP, which currently owns a 41.45% interest in
IMC-Agrico. For fiscal 1994, 1995 and 1996, payments from IMC-Agrico represented
58%, 54% and 54% of the Company's total revenues, respectively.
 
    Prior to January 1, 1997, the Main Pass operations were managed by
Freeport-McMoRan Oil and Gas Company ("FMOG"), an affiliate of FRP and FTX. For
fiscal 1994, 1995 and 1996, the Company paid FMOG $0.8 million, $0.9 million and
$1.0 million, respectively, for management services provided pursuant to this
arrangement. Since January 1, 1997, the Main Pass operations have been managed
by FRP and, after the Distributions, will be managed by the Company.
 
    Management believes that the terms of all of these agreements are, and
expects that the terms of all future agreements with affiliates will be, on
terms no less favorable to the Company than those that could be obtained in an
arm's-length transaction with an unaffiliated party.

                          DESCRIPTION OF CAPITAL STOCK
 
    The authorized capital stock of the Company consists of 100,000,000 shares
of Common Stock, $.01 par value per share, and 50,000,000 shares of preferred
stock, $.01 par value per share (the "Preferred Stock"). Upon completion of the
Distributions, approximately 10,346,578 shares of Common Stock will be
outstanding, and no shares of Preferred Stock will be outstanding. Prior to the
Distributions, there has been no public market for the Common Stock. Although
application has been made to have the Common Stock listed on the NYSE, there can
be no assurance that a market for the Common Stock will develop or, if
developed, will be sustained. See "Risk Factors--Absence of Trading Market." The
following summary description of the capital stock of the Company is qualified
in its entirety by reference to the Company's Certificate of Incorporation
("Certificate") and By-laws, copies of which are filed as exhibits to the
Registration Statement of which this Prospectus forms a part.
 
COMMON STOCK
 
    Each holder of Common Stock is entitled to one vote for each share of Common
Stock held of record on all matters as to which stockholders are entitled to
vote and stockholders may not cumulate votes for the election of directors.
Subject to any preferences accorded to the holders of the Preferred Stock, if
and when issued by the Board of Directors, holders of Common Stock are entitled
to dividends at such times and in such amounts as the Board of Directors may
determine. The Company does not intend to pay dividends for the foreseeable
future. See "Dividend Policy." Upon the dissolution, liquidation or winding up
of the Company, after payment of debts, expenses and the liquidation preference
plus any accrued dividends on any outstanding shares of Preferred Stock, the
holders of Common Stock will be entitled to receive all remaining assets of the
Company ratably in proportion to the number of shares held by them. Holders of
Common Stock have no preemptive, subscription or conversion rights and are not
subject to further calls or assessments, or rights of redemption by the Company.
The shares of Common Stock being distributed in the Distributions will be
validly issued, fully paid and nonassessable.
 
PREFERRED STOCK
 
    The Company's Board of Directors has the authority, without approval of the
stockholders, to issue shares of Preferred Stock in one or more series and to
fix the number of shares and rights, preferences and limitations of each series.
Among the specific matters that may be determined by the Board of Directors are
the dividend rights, the redemption price, if any, the terms of a sinking fund,
if any, the amount payable in the event of any voluntary liquidation,
dissolution or winding up of the affairs of the Company, conversion rights, if
any, and voting powers, if any.
 
    The existence of authorized but unissued Common Stock and undesignated
Preferred Stock may enable the Board of Directors to make more difficult or to
discourage an attempt to obtain control of the Company by means of a merger,
tender offer, proxy contest or otherwise. If, in the exercise of its fiduciary
responsibilities, the Board of Directors were to determine that a takeover
proposal was not in the Company's best interest, such shares could be issued by
the Board of Directors without stockholder approval in one or more transactions
that might prevent or make more difficult or costly the completion of the
takeover transaction by diluting the voting or other rights of the proposed
acquiror or insurgent stockholder group, by creating a substantial voting block
in institutional or other hands that might undertake to support the position of
the incumbent Board of Directors, by effecting an acquisition that might
complicate or preclude the takeover, or otherwise. The Company's Certificate
grants the Board of Directors broad power to establish the rights and
preferences of the authorized and unissued Preferred Stock, one or more series
of which could be issued entitling holders (i) to vote separately as a class on
any proposed merger or consolidation, (ii) to cast a proportionately larger vote
together with the Common Stock on any such transaction or for all purposes,
(iii) to elect directors having terms of office or voting rights greater than
those of other directors, (iv) to convert Preferred Stock into a greater number
of shares of Common Stock or other securities, (v) to demand redemption at a
specified price under prescribed circumstances related to a change of control or
(vi) to exercise other rights that could have the effect of
 
                                       57
<PAGE>
impeding a takeover. The issuance of shares of Preferred Stock pursuant to the
Board of Directors' authority described above may adversely effect the rights of
holders of the Common Stock.
 
    In addition, certain other charter provisions that are described below may
have the effect, either alone, in combination with each other, or combined with
the existence of authorized but unissued capital stock, of making more difficult
or discouraging an acquisition of the Company deemed undesirable by the Board of
Directors.
 
CERTAIN CHARTER AND BY-LAW PROVISIONS
 
   
    CLASSIFIED BOARD OF DIRECTORS
    
 
    The Company's Certificate and By-laws divide the members of the Board of
Directors into three classes, with each class to be as nearly equal in number of
directors as possible, serving staggered three-year terms.
 
   
    SIZE OF THE BOARD OF DIRECTORS; REMOVAL OF DIRECTORS; FILING OF VACANCIES ON
     THE BOARD OF DIRECTORS
    
 
    The Company's Certificate and By-laws provide that the number of directors
shall be fixed from time to time by the Board of Directors, but shall not be
fewer than the number required by Delaware law. Under the Company's Certificate,
a vote of 80% of the outstanding shares of capital stock entitled to vote
generally in an election of directors (the "Voting Stock") is required to remove
a director, and a director may only be so removed for cause involving fraud or a
violation of the duty of loyalty as determined by a final judgment of a court of
competent jurisdiction. The Certificate also provides that a newly created
directorship resulting from an increase in the number of directors may only be
filled by the Board of Directors and any vacancies on the Board of Directors
resulting from death, resignation, removal or other cause may be filled only by
the affirmative vote of both (a) a majority of the remaining directors then in
office and (b) a majority of all Continuing Directors (defined below), voting as
a separate group. In addition, these provisions specify that any director
elected to fill a vacancy on the Board of Directors will serve for the remainder
of the full term of the class of directors in which the new directorship was
created or in which the vacancy occurred.
 
   
    STOCKHOLDER ACTION BY UNANIMOUS CONSENT
    
 
    Under Delaware law, unless a corporation's certificate of incorporation
specifies otherwise, any action that could be taken by its stockholders at an
annual or special meeting may be taken, instead, without a meeting and without
notice to or a vote of other stockholders, if a consent in writing is signed by
holders of outstanding stock having voting power that would be sufficient to
take such action at a meeting at which all outstanding shares were present and
voted. The Company's Certificate provides that stockholder action may be taken
only at an annual or special meeting of stockholders. As a result, the Company's
stockholders may not act upon any matter except at a duly called meeting.
 
   
    AMENDMENT OF THE BY-LAWS
    
 
    Under Delaware law, the power to adopt, amend or repeal by-laws is conferred
upon the stockholders; however, a corporation may in its certificate of
incorporation also confer upon the board of directors the power to adopt, amend
or repeal its By-laws. The Company's Certificate and By-laws grant the Board of
Directors the power to adopt, amend and repeal the By-laws at any regular or
special meeting of the Board of Directors but only upon the affirmative vote of
both (i) a majority of the directors then in office and (ii) a majority of the
Continuing Directors (defined below), voting as a separate group. The Company's
stockholders may adopt, amend or repeal the By-laws but only at any regular or
special meeting of stockholders by an affirmative vote of 80% of the Voting
Stock.
 
                                       58
<PAGE>
   
    ADVANCE NOTICE OF STOCKHOLDER NOMINATIONS AND STOCKHOLDER BUSINESS
    
 
    The Company's By-laws permit stockholders to nominate a person for election
as a director or bring other matters before a stockholders' meeting only if such
stockholder has been, for at least one year, the beneficial owner of at least 1%
of the Voting Stock and only if written notice of such intent to nominate or
bring business before a meeting is given as described below.
 
    A stockholder intending to nominate a person for election as a director or
to propose other matters at a stockholders' meeting must furnish notice of such
intention to the Company's Secretary not more than 270 days and not less than 60
days in advance of the first anniversary of the preceding year's annual
stockholders' meeting, subject to certain exceptions applicable principally to
special meetings. The notice must, among other things, state the name, age and
address of the stockholder submitting the notice and any persons acting in
concert with such stockholder, the number of shares of Voting Stock held by the
stockholder and the dates such stock was acquired, and must include a
representation by such stockholder that he or she is a holder of record of the
Company's capital stock and intends to appear at the meeting in person and make
the nomination or bring up the specified matter.
 
    In the case of nominations for directors, the notice must also state (i) the
name, age, address and principal occupation of each nominee, (ii) a description
of all arrangements between the nominating stockholder and each nominee, (iii)
other information required to be included in a proxy statement pursuant to the
proxy rules of the Commission and (iv) the consent of each nominee to serve as a
director of the Company if elected and an affidavit of each such nominee
certifying that he meets the qualifications necessary to serve as a director of
the Company. In the case of other proposed business, the notice must set forth a
brief description of the business, the reasons for conducting such business at
the meeting and any material interest of the stockholder therein. The Chairman
of the stockholders' meeting will have the power to disregard any nomination or
other matter that fails to comply with these procedures. In addition, the
Company's Secretary may require any stockholders submitting a notice of intent
to make a nomination or bring other business before a stockholders' meeting to
furnish such documentary information as may be necessary to determine that such
stockholder has been for at least one year the beneficial owner of at least 1%
of the Voting Stock.
 
    With respect to any proposal by a stockholder to bring before a meeting any
matter other than the nomination of directors, the Company's By-laws provide
that the Company may disregard proposals that (i) are substantially duplicative
of a prior-received proposal to be voted upon at an upcoming meeting, (ii) deal
with substantially the same subject matter as a prior proposal that was voted
upon within the preceding five years and that failed to receive affirmative
votes in excess of certain specified levels, which range, depending on the
circumstances, between 3% and 10%, or (iii) in the judgment of the Board of
Directors, are not proper subjects for action by stockholders under Delaware
law.
 
   
    AMENDMENT OF CERTAIN PROVISIONS OF THE CERTIFICATE OF INCORPORATION
    
 
    Under Delaware law, unless the certificate of incorporation specifies
otherwise, a corporation's certificate of incorporation may be amended by the
affirmative vote of the majority of the stockholders. The Company's Certificate
requires the affirmative vote of 80% of the Voting Stock to amend, alter or
repeal certain provisions of the Certificate regarding (i) stockholder unanimous
written consents, (ii) the classification, filling of vacancies and removal of
members of the Board of Directors, (iii) the limitation of liability of
directors, (iv) business combinations and (v) amendments to the Certificate and
the By-laws.
 
   
    SPECIAL MEETINGS OF THE STOCKHOLDERS
    
 
    The Company's By-laws provide that special meetings of stockholders may be
called only by the Chairman of the Board of Directors, the Company's president
or a majority of the Board of Directors. Stockholders do not have the power to
call a special meeting.
 
                                       59
<PAGE>
   
    BUSINESS COMBINATIONS
    
 
    Delaware law provides that, unless otherwise provided in a corporation's
certificate of incorporation, a merger, sale of substantially all of the assets
or dissolution of a company requires the approval of the holders of a majority
of the outstanding capital stock. The Company's Certificate does not alter this
vote requirement generally, but provides that, if one of these transactions or
certain issuances, reclassifications or other transactions affecting the
Company's capital stock involves an Interested Stockholder (defined below), the
transaction must be approved (i) by a majority of both the directors then in
office and a majority of the Continuing Directors (defined below), voting as a
separate group and (ii) by the affirmative vote of (A) the holders of 80% of the
Voting Stock, voting together as a single class, and (B) 75% of the Voting Stock
other than Voting Stock beneficially owned by the Interested Stockholder. An
Interested Stockholder is any person who (i) beneficially owns 15% or more of
the Voting Stock or (ii) is an affiliate of the Company and, at any time within
two years prior to the date in question, beneficially owned 15% or more of the
then outstanding Voting Stock, other than the Company or its subsidiaries, or
any person owning any shares of the capital stock of the Company as of the date
of filing of the Company's Certificate and any person whose beneficial ownership
of any capital of the Company arises solely as a result of a trusteeship or a
custodial relationship with any employee stock ownership or other employee
benefit plan of the Company. A Continuing Director is any member of the Board of
Directors who is not an Interested Stockholder or an affiliate thereof and (i)
was a director prior to the time the Interested Stockholder became an Interested
Stockholder or (ii) was recommended or elected by a majority of the Continuing
Directors at a meeting at which a quorum consisting of a majority of the
Continuing Directors was present. In the absence of an Interested Stockholder,
the Continuing Directors shall mean all the directors then in office.
 
    This additional voting requirement does not apply if the transaction has
been approved by a majority of the Continuing Directors, or if all of the
following conditions have been met: (i) the aggregate amount of consideration
received per share by the holders meet certain "fair price" criteria, (ii) prior
to the consummation of the transaction (a) there has been no failure to declare
or pay dividends on any outstanding Preferred Stock or Common Stock, (b) the
Interested Stockholder has not received the benefits (except proportionately as
a stockholder) of any loans, advances or other financial assistance or tax
advantages provided by the Company, and (c) the Interested Stockholder has not
caused any material change in the Company's equity capital structure, and (iii)
the Interested Stockholder has not become the beneficial owner of any additional
shares of Voting Stock except as part of the transaction that resulted in such
Interested Stockholder becoming an Interested Stockholder or as a result of a
pro rata stock dividend.
 
    The Company is also subject to Section 203 of the DGCL, which imposes a
three-year moratorium on the ability of Delaware corporations to engage in a
wide range of specified transactions with any interested stockholder, defined to
include, among others, any person other than such corporation and any of its
majority-owned subsidiaries who own 15% or more of any class or series of stock
entitled to vote generally in the election of directors, unless, among other
exceptions, the transaction is approved by (i) the Board of Directors prior to
the date the interested stockholder obtained such status, or (ii) the holders of
two-thirds of the outstanding shares of each class or series of stock entitled
to vote generally in the election of directors, not including those shares owned
by the interested stockholder.
 
    The provisions described above may tend to deter any potential unfriendly
offers or other efforts to obtain control of the Company that are not approved
by the Board of Directors and thereby deprive the stockholders of opportunities
to sell shares of Common Stock at prices higher than the prevailing market
price. On the other hand, these provisions will tend to assure continuity of
management and corporate policies and to induce any person seeking control of
the Company or a business combination with the Company to negotiate on terms
acceptable to the then elected Board of Directors.
 
                                       60
<PAGE>
RIGHTS AGREEMENT
 
    The Company plans to adopt the Rights Agreement at or prior to the
Distributions, pursuant to which each share of Common Stock will include an
associated preferred share purchase right (a "Right"). Each Right will entitle
the registered holder to purchase from the Company one one-hundredth of a share
of Participating Preferred Stock, $.01 par value, for an exercise price to be
determined by the Board of Directors (the "Exercise Price"), subject to
adjustment. The Rights will be represented by the Common Stock certificates and
will be exercisable only after an entity acquires 15% or more of the outstanding
Common Stock or commences a tender offer that will result in the entity owning
15% or more of the Common Stock. After an entity acquires 15% or more of the
outstanding Common Stock, each Right would then entitle the holder (other than
the acquiring entity) to purchase, at the Exercise Price, the number of shares
of Common Stock or other securities of the Company (or, in certain situations,
the acquiring entity) having a market value of twice the Right's Exercise Price
(the "Flip-in Date"). The Rights will expire on the tenth anniversary of the
date it is entered into unless earlier redeemed by the Company, as described
below. Until a Right is exercised, the holder, as such, will have no rights as a
stockholder of the Company, including without limitation, the right to vote or
to receive dividends.
 
    The Board of Directors of the Company may, at its option, at any time prior
to the close of business on the Flip-in Date, redeem all (but not less than all)
the then outstanding Rights at a price to be determined by the Board of
Directors (the "Redemption Price"), as provided in the Rights Agreement.
Immediately upon the action of the Board of Directors of the Company electing to
redeem the Rights, without any further action and without any notice, the right
to exercise the Rights will terminate and each Right will thereafter represent
only the right to receive the Redemption Price in cash for each Right so held.
 
    The Rights will not prevent a takeover of the Company. However, the Rights
may cause substantial dilution to a person or group that acquires 15% or more of
the Common Stock unless the Rights are first redeemed by the Board of Directors
of the Company. The Rights are intended to encourage any person desiring to
acquire a controlling interest in the Company to do so through a transaction
negotiated with the Company's Board of Directors rather than through a hostile
takeover attempt. The Rights are intended to assure that any acquisition of
control of the Company will be subject to review by the Board to take into
account, among other things, the interests of all the Company's stockholders.
 
TRANSFER AGENT
 
    The transfer agent and registrar for the Common Stock is ChaseMelon
Shareholder Services, L.L.C.
 
LIMITATION OF DIRECTORS' AND OFFICERS' LIABILITY AND INDEMNIFICATION
 
    In accordance with the DGCL, the Company's Certificate contains provisions
eliminating the personal liability of the directors to the Company and its
stockholders for monetary damages for breaches of their fiduciary duties as
directors to the fullest extent permitted by Delaware law. By virtue of these
provisions, under current Delaware law, a director of the Company will not be
personally liable for monetary damages for a breach of his or her fiduciary duty
except for liability for (a) a breach of his or her duty of loyalty to the
Company or to its stockholders, (b) acts or omissions not in good faith or that
involve intentional misconduct or a knowing violation of law, (c) dividends or
stock repurchases or redemptions that are unlawful under Delaware law and (d)
any transaction from which he or she receives an improper personal benefit. In
addition, the Certificate provides that if Delaware law is amended to authorize
the further elimination or limitation of the liability of a director, then the
liability of the directors shall be eliminated or limited to the fullest extent
permitted by Delaware law, as amended. These provisions pertain only to breaches
of duty by directors as directors and not in any other corporate capacity, such
as officers, and limit liability only for breaches of fiduciary duties under
Delaware corporate law and not for violations of other laws such as the federal
securities laws.
 
                                       61
<PAGE>
    As a result of the inclusion of such provisions, stockholders may be unable
to recover monetary damages against directors for actions taken by them that
constitute negligence or gross negligence or that are in violation of their
fiduciary duties, even though it may be possible to obtain injunctive or other
equitable relief with respect to such actions. If equitable remedies are found
not to be available to stockholders in any particular case, stockholders may not
have any effective remedy against the challenged conduct. These provisions may
have the effect of reducing the likelihood of derivative litigation against
directors that might have benefitted the Company.
 
    The Company believes that such provisions are necessary to attract and
retain qualified individuals to serve as directors. In addition, such provisions
will allow directors to perform their duties in good faith without concern for
the application of monetary liability on a retrospective basis in the event that
a court determines their conduct to have been negligent or grossly negligent.
 
    The Company's By-laws require the Company to indemnify its officers and
directors against expenses and costs, judgments, settlements and fines incurred
in the defense of any claim, including any claim brought by or in the right of
the Company, to which they were made parties by reason of being or having been
officers or directors.

                    COMPARISON OF THE RIGHTS OF STOCKHOLDERS
 
    The following is a summary of material differences between the rights of
holders of the Company's Common Stock and the rights of holders of FTX Common
Stock. As each of Freeport Sulphur and FTX is organized under the laws of
Delaware, these differences arise principally from provisions of the certificate
of incorporation and by-laws of each of Freeport Sulphur and FTX. See
"Description of Capital Stock."
 
    The following summaries do not purport to be complete statements of the
rights of Freeport Sulphur stockholders under the Freeport Sulphur Certificate
and By-laws as compared with the rights of FTX stockholders under the FTX
Restated Certificate of Incorporation, as amended (the "FTX Certificate"), and
Amended and Restated By-laws (the "FTX By-laws") or a complete description of
the specific provisions referred to herein. The identification of specific
differences is not meant to indicate that other equal or more significant
differences do not exist. These summaries are qualified in their entirety by
reference to the DGCL and governing corporate instruments of Freeport Sulphur
and FTX, to which stockholders are referred.
 
DIRECTORS
 
    Freeport Sulphur directors may be removed at any time by the vote of 80% of
the stockholders entitled to vote for such director, but only for cause.
Vacancies or newly created directorships in the Freeport Sulphur Board of
Directors may be filled for the unexpired term only by a majority vote of both
the remaining directors and of the Continuing Directors, defined above.
 
    The FTX Certificate and FTX By-laws do not provide for removal of directors
for cause, however, under the DGCL, where a corporation's board is classified,
stockholders may remove directors only for cause. The FTX Certificate provides
that a newly created directorship resulting from any increase in the number of
directors and any vacancies on the FTX Board resulting from death, resignation,
disqualification, removal or other reason may be filled solely by the
affirmative vote of a majority of the remaining directors then in office, even
though less than a quorum of the FTX Board.
 
RIGHTS AGREEMENT
 
    Freeport Sulphur has adopted the Rights Agreement as discussed above.
Subject to the terms of the Rights Agreement, if an entity acquires 15% or more
of the outstanding Common Stock, each holder of a Right (other than the
acquiring entity) would be entitled to purchase a number of shares of Common
Stock or other securities of Freeport Sulphur (or, in certain situations, the
acquiring entity) having a market value of twice the Right's exercise price.
 
    FTX does not have a stockholder rights plan.
 
BUSINESS COMBINATIONS
 
    Delaware law provides that, unless otherwise provided in a corporation's
certificate of incorporation, a merger, sale of substantially all of the assets
or dissolution of a company requires the approval of the holders of a majority
of the outstanding capital stock. Freeport Sulphur's Certificate generally
provides that if one of these transactions, or other reclassifications or
transactions affecting Freeport Sulphur's capital stock, involves a party owning
in excess of 15% of Freeport Sulphur's outstanding Common Stock, the transaction
must be approved (i) by a majority of the directors then in office and a
majority of the Continuing Directors and (ii) by the affirmative vote of 75% of
the outstanding Common Stock entitled to vote, other than the stock held by the
acquiring party. This additional voting requirement does not apply if the
transaction has been approved by a majority of the Continuing Directors, or if
certain other conditions discussed above have been met. See "Description of
Capital Stock--Business Combinations."
 
    The FTX Certificate has similar provisions requiring that certain

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon completion of the Distributions, the Company will have 10,346,578
shares of Common Stock outstanding, all of which will be owned by the FTX
stockholders and the FRP public unitholders. All such shares will be freely
transferable without restriction under the 1933 Act except by persons who are
deemed to be an "affiliate" of the Company as defined in Rule 144 under the 1933
Act or by persons who may be deemed to be an "affiliate" of FTX or IGL as
defined in paragraphs (c) and (d) of Rule 145 under the 1933 Act. Under the
Company Adjusted Stock Award Plan, the Company will issue options to purchase
Common Stock in substitution for certain options to purchase FTX Common Stock
outstanding under various FTX employee benefit plans at the time of the Merger.
See "Management--The Employee Benefits Agreement." In addition to such stock
options, the Company may grant additional options to purchase Common Stock
pursuant to the Directors Plan and Stock Plan subject to certain restrictions.
See "Management--Stock Option Plans." The Company currently expects to file a
registration statement under the 1933 Act to register shares reserved for

the Company's Stock Option Plans after the effective date of such Registration
Statement (other than shares issued to "affiliates" as such term is defined
under the 1933 Act) generally will be freely tradeable without restriction or
further registration under the 1933 Act.
 
    Pursuant to Rules 144 and 145 under the 1933 Act, the sale of Common Stock
held by affiliates of the Company, former affiliates of FTX or affiliates of IGL
will be subject to certain restrictions. Such persons may sell Common Stock
under such rules only if (i) the Company has filed all reports required to be
filed by Section 13 or 15(d) of the 1934 Act during the preceding twelve months,
(ii) such Common Stock is sold in a "broker's transaction" which is defined
under the 1933 Act as a sale in which (a) the seller does not solicit or arrange
for orders to buy the securities, (b) the seller does not make any payment other
than to the broker, (c) the broker does no more than execute the order and
receive a normal commission and (d) the broker does not solicit customer orders
to buy the securities, and (iii) such sale and all other sales made by such
person within the preceding three months do not exceed the greater of (x) one
percent of the outstanding shares of Common Stock or (y) the average weekly
trading volume of Common Stock on the New York Stock Exchange during the
four-week period preceding the sale. Any former affiliate of FTX who is not an
affiliate of IGL or the Company after the Merger may sell Common Stock without
restriction following the first anniversary of the Effective Time of the Merger.

To Freeport-McMoRan Sulphur Inc.:
 
    We have audited the accompanying balance sheet of Freeport-McMoRan Sulphur
Inc. (a Delaware corporation) as of August 26, 1997. This balance sheet is the
responsibility of the Company's management. Our responsibility is to express an
opinion on this balance sheet based on our audit.
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the balance sheet is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the balance sheet. 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 audit provides a reasonable basis for our opinion.
 
    In our opinion, the balance sheet referred to above presents fairly, in all
material respects, the financial position of Freeport-McMoRan Sulphur Inc. as of
August 26, 1997 in conformity with generally accepted accounting principles.

     The accompanying note is an integral part of this financial statement.
 
                             NOTE TO BALANCE SHEET
 
    On August 26, 1997, IMC Global Inc. ("IGL") and Freeport-McMoRan Inc.
("FTX") executed a definitive agreement for FTX to merge with and into IGL (the
"Merger"). The terms of the Merger provide that each share of FTX common stock
will be converted into the right to receive (i) 0.90 of a share of IGL common
stock, (ii) one-third of a warrant exercisable for a share of IGL common stock
and (iii) a proportionate number of shares of a newly formed company
(Freeport-McMoRan Sulphur Inc.) that would be held by FTX immediately prior to
consummation of the Merger. Completion of the Merger is subject to, among other
things, approval of the definitive merger agreement by the IGL and FTX
shareholders and the expiration or early termination of the waiting period under
the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (early termination
having been granted). Both companies expect the Merger to be completed by the
end of 1997.
 
    On August 26, 1997, Freeport-McMoRan Resource Partners, Limited Partnership
("FRP") acquired 100 shares of Freeport-McMoRan Sulphur Inc. (the "Company")
common stock, par value $0.01 per share for a $100.00 subscription. The Company,
a Delaware corporation, was formed for the purpose of owning and operating the
sulphur business and the 58.3% interest in the Main Pass sulphur and oil
operations owned by FRP, together with the 25.0% interest in Main Pass owned by
IGL, a joint venture partner with FRP, (collectively, the "Transferred
Businesses"). The Company will operate the Transferred Businesses and assume
substantially all liabilities related to the Transferred Businesses.
 
    Immediately prior to the Merger, IGL will transfer its 25% interest in Main
Pass to FRP. FRP will then contribute the Transferred Businesses to the Company.
 
    FRP intends to distribute 100% of the Company's common stock to its public
unitholders and to FTX, the administrative managing general partner and the
owner of 51.6% of FRP's partnership interest. FTX will then distribute the
shares of common stock that it receives from FRP to the FTX stockholders on a
pro rata basis. Until such distributions, the Company will be wholly owned by
FRP. FTX shall bear all of the costs and expenses incurred in connection with
the distributions.
 
    Each share of the Company's common stock will also represent one right under
the Company's Preferred Stock Purchase Rights Plan. The rights are not currently
exercisable. Under certain circumstances the rights become exercisable for the
Company's preferred stock or the stock of a person effecting certain
reorganizations, mergers or combinations with the Company.

    We have audited the accompanying balance sheets of the FRP Transferred
Businesses (Note 1) of Freeport-McMoRan Resource Partners, Limited Partnership
("FRP") as of December 31, 1996 and 1995, and the related statements of
operations, cash flow and changes in net assets to be transferred for each of
the years in the three-year period ended December 31, 1996. These financial
statements are the responsibility of FRP'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 financial position of the FRP Transferred
Businesses as of December 31, 1996 and 1995 and the results of their operations
and cash flow for each of the years in the three-year period ended December 31,
1996 in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
1.  ORGANIZATION AND OPERATIONS AND BASIS OF PRESENTATION
 
    ORGANIZATION AND OPERATIONS.  On August 26, 1997, Freeport-McMoRan Resource
Partners, Limited Partnership ("FRP") acquired 100 shares of Freeport-McMoRan
Sulphur Inc. (the "Company" or "Freeport Sulphur") common stock, par value $0.01
per share, for a $100 subscription. The Company, a Delaware corporation, was
formed for the purpose of owning and operating the sulphur business and the
58.3% interest in the Main Pass sulphur and oil operations owned by FRP (the
"FRP Transferred Businesses"), together with the 25.0% interest in Main Pass
owned by IMC Global Inc. ("IGL"), a joint venture partner with FRP. FRP intends
to transfer these assets and related liabilities to the Company in connection
with the merger of Freeport-McMoRan Inc. ("FTX"), the administrative managing
general partner and the owner of 51.6% of FRP's partnership interest, with and
into IGL (the "Merger").
 
    FRP intends to distribute 100% of the Company's common stock to its public
unitholders and to FTX. FTX will then distribute the shares of Freeport Sulphur
common stock that it receives from FRP to the FTX stockholders on a pro rata
basis in connection with the Merger.
 
    BASIS OF PRESENTATION.  The FRP Transferred Businesses operated as an
integral part of FRP during the periods covered by these financial statements,
which have been prepared from the books and records of FRP. Certain data has
been extracted from FRP records, or in certain cases derived on the basis of
allocations between the FRP Transferred Businesses and FRP's other businesses,
for purposes of presentation in the accompanying financial statements. No
interest expense has been allocated to the FRP Transferred Businesses as no
interest costs have been incurred in the past and no debt previously recorded by
FRP will be assumed by the Company. Intercompany balances between FRP and the
FRP Transferred Businesses have related to various general and administrative
and similar charges and have been settled monthly. FRP is not a taxable entity
and historically has not provided income taxes related to the FRP Transferred
Businesses. The related net deferred tax liability that would have been recorded
by the Company is disclosed in Note 5, but is not included in the accompanying
balance sheets. FTX provides benefit plans for those employees that are expected
to become Freeport Sulphur employees upon completion of the Merger. FTX will
transfer certain liabilities related to these plans to the Company and pay cash
to the Company for the assumption of certain of these liabilities as discussed
further in Note 6. The liabilities and cash amounts are not reflected in the
accompanying balance sheets.
 
   
    The FRP Transferred Businesses balance sheet as of September 30, 1997 and
the related statements of operations, cash flow and changes in net assets to be
transferred for the nine-month periods ended September 30, 1997 and 1996 are
unaudited. These unaudited financial statements have been prepared from the
books and records of FRP and reflect all adjustments which are, in the opinion
of management, necessary for a fair statement of the results for the periods.
All such adjustments are, in the opinion of management, of a normal recurring
nature.
    
 
    Upon completion of the merger, the combined financial statements of the
Company will include the operations of the FRP Transferred Businesses and the
25.0% interest in Main Pass owned by IGL. The Company will account for the 25.0%
interest in Main Pass owned by IGL at fair value under purchase accounting.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    USE OF ESTIMATES.  The preparation of the FRP Transferred Businesses
financial statements in conformity with generally accepted accounting principles
requires management to make estimates and assumptions that affect the amounts
reported in these financial statements and accompanying notes. The
 
                                      F-9

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
more significant areas requiring the use of management estimates include
reclamation and environmental obligations, postretirement and other employee
benefits, future cash flows associated with assets and useful lives for
depreciation and amortization. Actual results could differ from those estimates.
 
    CASH AND CASH EQUIVALENTS.  Highly liquid investments purchased with a
maturity of three months or less are considered cash equivalents.
 
    INVENTORIES.  Inventories are stated at the lower of average cost or market.
 
    PROPERTY, PLANT AND EQUIPMENT.  Property, plant and equipment are carried at
cost, including interest capitalized during the construction and development
period. Expenditures for replacements and improvements are capitalized.
Depreciation for mining and production assets, including mineral interests, is
determined using the unit-of-production method based on estimated recoverable
reserves. Other assets are depreciated on a straight-line basis over estimated
useful lives of 17 to 30 years for buildings and 5 to 25 years for machinery and
equipment.
 
   
    In 1995, the Financial Accounting Standards Board (FASB) issued Statement of
Financial Accounting Standards No. 121 (SFAS 121) which requires an assessment
of the carrying value of long-lived assets and a reduction of such carrying
value to fair value when events or changes in circumstances indicate that the
carrying amount may not be recoverable. As a result of its most recent review of
its sulphur assets, FRP and FTX concluded that the carrying value of the Main
Pass sulphur assets exceeded the undiscounted estimated future net cash flows,
such that an impairment writedown of $416.4 million (based on September 30, 1997
book values) was required. A similar analysis of the Culberson sulphur assets,
based on a reassessment of recoverable reserves utilizing recent production
history, also indicated an impairment writedown of $9.0 million (based on
September 30, 1997 book values) was required. Fair values were estimated using
discounted estimated future net cash flows related to these assets. The
writedowns to fair value were recorded by FRP and FTX in the third quarter of
1997 and are reflected in the unaudited September 30, 1997 financial statements
as additional depreciation and amortization charges. Future operating results of
Freeport Sulphur will reflect lower depreciation and amortization expense as a
result of these writedowns.
    
 
    OIL CAPITALIZED COSTS.  Oil producing operations are reflected using the
successful efforts method of accounting. Costs of leases, productive exploratory
wells and development activities are capitalized. Other exploration costs are
expensed. Depreciation and amortization is determined on a field-by-field basis
using the unit-of-production method. Gain or loss is included in income when
properties are sold.
 
    ENVIRONMENTAL REMEDIATION AND COMPLIANCE.  The FRP Transferred Businesses
incur significant costs for environmental programs and projects. Expenditures
pertaining to future revenues from operations are capitalized. Expenditures
resulting from the remediation of conditions caused by past operations which do
not contribute to future revenue generation are expensed. Liabilities are
recognized for remedial activities when the efforts are probable and the cost
can be reasonably estimated.
 
    Estimated future expenditures to restore properties and related facilities
to a condition that complies with environmental and other regulations are
accrued over the life of the properties. The future expenditures are estimated
based on current costs, laws and regulations. As of December 31, 1996, the
balance sheet included a $57.6 million accrual for abandonment and restoration
of non-operating sulphur assets, including $22.5 million which will be
reimbursed by third parties. Total estimated abandonment cost for Main Pass oil
operations is $10 million and $6.2 million was accrued at December 31, 1996. The
current

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
portion of reclamation and mine shutdown reserves includes $7.9 million which
will be reimbursed by third parties. The FRP Transferred Businesses' share of
abandonment and restoration costs for its two operating sulphur mines is
estimated to total approximately $50 million, $18.3 million of which had been
accrued at December 31, 1996, with essentially all costs being incurred after
mine closure. These estimates are by their nature imprecise and can be expected
to be revised over time because of changes in government regulations,
operations, technology and inflation.
 
    A rollforward of the reclamation and mine shutdown reserves follows (in

    NEW ACCOUNTING STANDARDS.  In June 1997, the FASB issued SFAS 130,
"Reporting Comprehensive Income," and SFAS 131, "Disclosures About Segments of
an Enterprise and Related Information." SFAS 130 establishes standards for the
reporting and display of comprehensive income in the financial statements.
Comprehensive income is the total of net income and all other nonowner changes
in equity. SFAS 131 requires that companies disclose segment data based on how
management makes decisions about allocating resources to segments and measuring
their performance. SFAS 130 and 131 are effective for 1998. Adoption of these
standards is not expected to result in material changes to the FRP Transferred
Businesses' financial statements, financial position or results of operations.

4.  MANAGEMENT SERVICES
 
    FTX has provided certain management and administrative services to FRP (and
thus the FRP Transferred Businesses) including technical, administrative,
accounting, financial, tax and other services under a management services
agreement. The costs of such services, which include related overhead, have been
allocated to the FRP Transferred Businesses based on time spent by FTX employees
in the conduct of the FRP Transferred Businesses' business activities. Such
costs are non-interest bearing and reimbursed monthly. Management believes the
costs for such services do not differ materially from the costs that would have
been incurred had the relevant personnel providing these services been employed
directly by the FRP Transferred Businesses. The total amount charged by FTX to
the FRP Transferred Businesses for such services was $2.0 million in 1996, $15.9
million in 1995 (including $7.0 million for stock appreciation rights costs
resulting from the rise in FTX's common stock price during the year) and $8.8
million in 1994.
 
    Beginning in 1996, FM Services Company (FMS), an entity owned 50 percent
each by FTX and Freeport-McMoRan Copper & Gold Inc., a former subsidiary of FTX,
began providing most of the services previously provided by FTX on a similar
cost-reimbursement basis, totaling $6.7 million for 1996. Prior to 1997, FTX
operated the Main Pass oil facilities and charged the FRP Transferred Businesses
$1.3 million in 1996, $1.0 million in 1995 and $0.8 million in 1994 for
specified overhead and other costs. Beginning in 1997, FRP operated the
facilities and upon consummation of the Merger, Freeport Sulphur will operate
the Main Pass oil facilities.
 
    After the Merger, FMS will continue to provide similar management and
administrative services to Freeport Sulphur pursuant to a management services
agreement. As a result, management believes general and administrative expenses
will not differ materially from those reported in these financial statements,
except that Freeport Sulphur will not have stock appreciation rights and it is
not possible to predict the impact of compensation expenses that are associated
with performance.

5.  INCOME TAXES
 
    Because FRP is not a taxable entity, historically it has not provided for
income taxes. Freeport Sulphur will record deferred income taxes pursuant to
SFAS 109 immediately upon the transfer of assets and liabilities and will
recognize the income tax effect of deferred taxes at that time. The components
of deferred taxes that would have been recorded by Freeport Sulphur as of
December 31, 1996 and 1995, based upon temporary differences existing at that
time, including the estimated deferred compensation, postretirement and pension
benefits related to the FRP Transferred Businesses, follow (in thousands):

    PENSIONS.  Substantially all employees have been covered by FTX's or FMS's
defined benefit plans. Additionally, unfunded nonqualified plans are sponsored
for those participants in the qualified defined benefit plans whose benefits are
limited under federal income tax laws. The accumulated benefits and plan assets
were not separately determined and amounts allocated to the FRP Transferred
Businesses under these plans have not been material. In connection with the
Merger, Freeport Sulphur will form its own defined benefit plans and FTX will
transfer to the new Freeport Sulphur plan (for the qualified plan), or to
Freeport Sulphur (for the nonqualified plan), assets and liabilities pertaining
to those FTX employees who will become Freeport Sulphur employees. The Freeport
Sulphur plans initially will have substantially the same provisions as the FTX
plans and will provide credit for prior FTX service. The final actuarial
valuation will be made as of the date of the consummation of the Merger. The
estimated actuarial liability related to the new Freeport Sulphur plans as of
January 1, 1998 follows (in thousands) and is not included in the FRP
Transferred Businesses balance sheets.

services), $4.7 million in 1995 ($0.2 million and $4.5 million, respectively)
and $4.3 million in 1994 ($0.2 million and $4.1 million, respectively). The FRP
Transferred Businesses' share of the FMS plan was not significant for 1996.
 
    In connection with the Merger, Freeport Sulphur will assume the liability
for the portion of FTX's postretirement benefit liability related to active
employees transferred to Freeport Sulphur and FTX will pay Freeport Sulphur cash
for the amount of the liability. The final actuarial determination will be made
upon consummation of the Merger. The estimated actuarial information as of
January 1, 1998 follows (in thousands) and neither the liability nor the cash
payment is included in the FRP Transferred Businesses balance sheets:

    The initial health care cost trend rate used was 8 percent for 1998,
decreasing 0.5 percent per year until reaching 5 percent. A one percent increase
in the trend rate would increase the amounts by approximately 10 percent. The
discount rate used was 7.75 percent. Freeport Sulphur will have the right to
modify or terminate these benefits.
 
    In connection with the Merger, Freeport Sulphur will assume a liability to
IGL for a portion of IGL's postretirement benefit costs relating to certain
retired employees of FTX. An actuarial determination will be made of the
liability associated with these employees upon consummation of the Merger.
Freeport Sulphur estimates the liability to be approximately $10 million.
 
    STOCK OPTIONS.  Freeport Sulphur will adopt an Adjusted Stock Award Plan to
provide for the issuance of fixed options to holders of FTX fixed options and
FTX stock appreciation rights (SARs). The fixed options granted under the
Adjusted Stock Award Plan will reflect the option holder's economic position
under the FTX options as adjusted for the proportionate market value of Freeport
Sulphur shares at the time of the Merger. The number of fixed options to be
issued by Freeport Sulphur will be based upon the number of FTX options and SARs
outstanding as of the date of consummation of the Merger, adjusted for the
distribution ratio of Freeport Sulphur shares to FTX shares. As of December 31,
1996, FTX had outstanding a total of 2.1 million fixed options and SARs, of
which stock options representing 0.9 million shares were exercisable at an
average option price of $19.01 per share. Compensation expense for the aggregate
intrinsic value of the FTX SARs has already been recorded in the accompanying
FRP Transferred Businesses financial statements through allocations of general
and administrative costs from FTX. As these SARs will be converted to fixed
options under the Freeport Sulphur Adjusted Stock Award Plan, the related
accrued SAR liability will be recorded as additional paid-in capital in the
Freeport Sulphur balance sheets.
 
    Freeport Sulphur will adopt the disclosure only provisions of SFAS 123 and
will continue to apply APB Opinion No. 25 and related interpretations in
accounting for its stock based compensation plans. Had compensation cost for
FTX's fixed stock option grants been determined in accordance with SFAS 123, the
FRP Transferred Businesses would have been allocated additional charges totaling
$1.2 million ($0.7 million to pro forma net income) in 1996 and none in 1995.

6.  PENSION AND OTHER EMPLOYEE BENEFITS (CONTINUED)
    Freeport Sulphur will adopt other benefit plans, certain of which are
related to its performance, which costs will be recognized in general and
administrative expense. Upon consummation of the Merger, Freeport Sulphur will
also assume certain FTX liabilities totaling approximately $0.4 million under
its plans related to those employees transferred from FTX to Freeport Sulphur in
exchange for an equal cash payment.
 
7.  COMMITMENTS AND CONTINGENCIES
 
    LONG-TERM CONTRACTS AND OPERATING LEASES.  FRP Transferred Businesses'
minimum annual contractual charges under noncancelable long-term contracts and
operating leases total $176.9 million, with $18.2 million in 1997, $14.0 million
in 1998, $13.6 million in 1999, $13.5 million in 2000 and $13.4 million in 2001.
 
    ENVIRONMENTAL.  The FRP Transferred Businesses have made, and will continue
to make, expenditures for protection of the environment. The FRP Transferred
Businesses are subject to contingencies as a result of environmental laws and
regulations. The related future cost is indeterminable because of such factors
as the unknown timing and extent of the corrective actions that may be required
and the application of joint and several liability.
 
8.  ACQUISITIONS
 
    In January 1995, FRP acquired essentially all of the domestic assets of
Pennzoil Co.'s sulphur division, including the Culberson sulphur mine in West
Texas. Under the terms of the purchase, Pennzoil will receive quarterly payments
from FRP over 20 years based on the prevailing price of sulphur. These payments
totaled $2.0 million in 1996 and $5.2 million in 1995. The installment payments
may be terminated earlier either by FRP through the exercise of a $65 million
call option or by Pennzoil through the exercise of a $10 million put option.
Neither option may be exercised prior to 1999. Freeport Sulphur will assume the
terms of the purchase agreement with Pennzoil. The purchase price allocation
follows (in thousands):

9.  BUSINESS SEGMENTS
 
    FRP Transferred Businesses operates in two business segments, sulphur and
oil. Frasch sulphur is produced through the offshore Louisiana Main Pass mine
and the Culberson mine in West Texas. The sulphur business segment also includes
an extensive logistics network, including sulphur terminaling and

transportation assets, and purchases of recovered sulphur. Oil is produced at
Main Pass from the same geologic formation that holds the deposit's sulphur.
 
    A significant portion of the sulphur production is sold to the IMC-Agrico
Joint Venture (IMC-Agrico), a chemical fertilizer producer jointly owned by IGL
and FRP, under a long-term supply contract that extends for as long as
IMC-Agrico's operations have a requirement for sulphur. As a percentage of total
FRP Transferred Businesses revenues, sales to IMC-Agrico totaled 54% in 1996,
54% in 1995 and 58% in 1994. Oil produced from Main Pass is sold to two major
Gulf Coast refining companies. As a percentage of total FRP Transferred
Businesses revenues, oil sales to one of these refining companies, Amoco,
totaled 12% in 1996, 11% in 1995 and 19% in 1994. No other single customer
accounted for greater than 10% of total revenues in 1994 through 1996. The
Company's definition of its business segments is not expected to change as a
result of the adoption of SFAS 131.

    Subsequent to December 31, 1996, proved undeveloped reserve estimates were
revised downward by approximately 1 million barrels to reflect recent drilling
results.
 
    STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS FROM PROVED OIL
RESERVES (UNAUDITED). The standardized measure of discounted future net cash
flows and changes therein relating to the proved oil reserves of the FRP
Transferred Businesses were computed using reserve valuations based on
regulations prescribed by the SEC. These regulations provide for the use of
current oil prices (escalated only when known and determinable price changes are
provided by contract and law) in the projection of future net cash flows.

                    NOTES TO PRO FORMA FINANCIAL STATEMENTS
 
   
The accompanying Pro Forma Statements of Income have been prepared assuming the
transaction discussed below occurred on January 1, 1996, whereas the Pro Forma
Condensed Balance Sheet assumes the transaction occurred on September 30, 1997.
The pro forma financial statements are not necessarily indicative of the results
that would have been achieved nor are they indicative of future results.
    
 
1. FRP TRANSFERRED BUSINESSES AND IGL TRANSFERRED BUSINESSES
 
    BACKGROUND.  On August 26, 1997, IMC Global Inc. ("IGL") and
Freeport-McMoRan Inc. ("FTX") executed a definitive agreement for FTX to merge
with and into IGL (the "Merger"). The terms of the Merger provide that each
share of FTX common stock will be converted into the right to receive (i) 0.90
of a share of IGL common stock, (ii) one-third of a warrant exercisable for a
share of IGL common stock and (iii) a proportionate number of shares of a newly
formed company (Freeport-McMoRan Sulphur Inc.) that would be held by FTX
immediately prior to consummation of the Merger. Completion of the Merger is
subject to, among other things, approval of the definitive merger agreement by
the IGL and FTX shareholders and the expiration or early termination of the
waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976
(early termination having been granted). Both companies expect the Merger to be
completed by the end of 1997.
 
    In connection with the Merger, Freeport-McMoRan Resource Partners, Limited
Partnership, a Delaware limited partnership that is 51.6% owned by FTX ("FRP"),
will contribute to Freeport-McMoRan Sulphur Inc. ("Freeport Sulphur"), a newly
formed subsidiary of FRP, certain assets and liabilities described below and the
shares of Freeport Sulphur will be distributed to the FRP unitholders, including
FTX. FTX will then distribute its Freeport Sulphur shares to its stockholders as
part of the Merger consideration.
 
    Among the assets that will be contributed by FRP to Freeport Sulphur is
FRP's 58.3% interest in the Main Pass sulphur and oil joint venture (the "Main
Pass Joint Venture") in which IGL also has a 25% interest. The Main Pass Joint
Venture is primarily a sulphur mining operation, with the related oil deposit
being located in the same caprock containing the sulphur reserves.
 
    Immediately prior to the Merger, IGL will transfer its 25% interest in the
Main Pass Joint Venture to FRP (the "IGL Transferred Businesses"). FRP will then
contribute to Freeport Sulphur the IGL Transferred Businesses, and the FRP
Transferred Business; including FRP's interest in the Main Pass Joint Venture,
FRP's Culberson sulphur mine in West Texas (acquired from Pennzoil Company in
1995) and various related sulphur terminaling and transportation assets in the
Gulf Coast area.
 
   
    The pro forma balance sheet information reflects the pro forma effects of
the contribution of the assets and liabilities attributable to the FRP
Transferred Businesses and the IGL Transferred Businesses, reflected at
September 30, 1997 historical cost. While no consideration will actually be paid
by FRP to IGL for the IGL Transferred Businesses, the receipt of the IGL
Transferred Businesses will be recorded by FRP at fair value. The estimated fair
value of the property, plant and equipment to be contributed by IGL was based on
the same assumptions applied in the impairment assessment of FRP's sulphur
assets as discussed in Note 3. The pro forma income statement information
reflects the pro forma results of the FRP Transferred Businesses and the
historical revenues and direct operating expenses of the IGL Transferred
Businesses for the periods presented.
    
 
2. OTHER ADJUSTMENTS
 
    a.  Upon consummation of the Merger, FTX will (i) reimburse Freeport Sulphur
$6.3 million for certain employee benefits obligations totaling $26.7 million
which Freeport Sulphur will assume relating to

2. OTHER ADJUSTMENTS (CONTINUED)
transferred employees who will become Freeport Sulphur employees and (ii)
establish an operating cash balance of $2.0 million for ongoing Freeport Sulphur
operations.
 
   
    b.  Reflects estimated IGL Transferred Businesses customer receivable
balance ($2.9 million) for its share of sulphur production taken in-kind less
intercompany balances.
    
 
   
    c.  Reflects estimated sulphur and oil inventory balances attributable to
the IGL Transferred Businesses.
    
 
   
    d.  Reflects net deferred tax asset associated with differences in book and
tax asset and liability bases as per Statement of Financial Accounting Standards
No. 109 (SFAS 109) after giving effect to the impairment assessment of FRP's
sulphur assets discussed in Note 3.
    
 
   
    e.  Reflects reductions in accounts payable related to amounts to be settled
by IGL pursuant to the Merger and intercompany balances.
    
 
   
    f.  Reflects elimination of management and similar fees charged IGL by FRP
as operator of the Main Pass Joint Venture.
    
 
   
    g.  Reflects estimated $1.0 million annual increase in insurance cost
related to the IGL Transferred Businesses and an estimated reduction in employee
benefit costs.
    
 
   
    h.  Reflects estimated depreciation and amortization, including reclamation
and shutdown reserve accruals, for the IGL Transferred Businesses based on their
proportionate share of future costs and the estimated fair value of the
property, plant and equipment to be contributed by IGL to FRP.
    
 
   
    i.  Reflects estimated identifiable increase in Freeport Sulphur general and
administrative expenses relative to public entity-related costs ($1.05 million
annually) and estimated general and administrative expenses attributable to the
IGL Transferred Businesses which were previously recovered from IGL.
    
 
   
    j.  Reflects estimated applicable income tax provision associated with the
IGL Transferred Businesses and other pro forma income statement adjustments.
    
 
3. IMPAIRMENT ASSESSMENT OF SULPHUR ASSETS.
 
   
    In 1995, the Financial Accounting Standards Board (FASB) issued Statement of
Financial Accounting Standards No. 121 (SFAS 121) which requires an assessment
of the carrying value of long-lived assets and a reduction of such carrying
value to fair value when events or changes in circumstances indicate that the
carrying amount may not be recoverable. As a result of its most recent review of
its sulphur assets, FRP and FTX concluded that the carrying value of the Main
Pass sulphur assets exceeded the undiscounted estimated future net cash flows,
such that an impairment writedown of $416.4 million (based on September 30, 1997
book values) was required. A similar analysis of the Culberson sulphur assets,
based on a reassessment of recoverable reserves utilizing recent production
history, also indicated an impairment writedown of $9.0 million (based on
September 30, 1997 book values) was required. Fair values were estimated using
discounted estimated future cash flows related to these assets and the
writedowns are reflected in the pro forma September 30, 1997 financial
statements as additional accumulated depreciation and amortization charges. The
writedowns to fair value were recorded by FRP and FTX in the third quarter of
1997.

4. PRO FORMA EARNINGS PER SHARE.
 
    Pro forma earnings per share is computed by dividing pro forma net income by
pro forma common and common equivalent shares outstanding. Pro forma common and
common equivalent shares are based on the number of Freeport Sulphur shares
expected to be issued and outstanding (10,346,578) and the expected number of
common stock equivalents under the Freeport Sulphur Adjusted Stock Award Plan.
In February 1997, the FASB issued SFAS 128, "Earnings Per Share," which
simplifies the computation of earnings per share (EPS). SFAS 128 is effective
for financial statements issued for periods ending after December 15, 1997 and
requires restatement for all prior period EPS data presented. Adoption of SFAS
128 would not change Freeport Sulphur's pro forma EPS.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Freeport-McMoRan Sulphur Inc.:
 
    We have audited the accompanying statement of gross sulphur and oil revenues
and direct operating expenses of the assets to be acquired (IGL Transferred
Businesses) by Freeport-McMoRan Sulphur Inc. (see Note 1) for the year ended
December 31, 1996. This statement is the responsibility of management. Our
responsibility is to express an opinion on the statement based on our audit.
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the statements are free of material
misstatements. 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 presentation of the statements. We
believe our audit provides a reasonable basis for our opinion.
 
    The accompanying statement presents only the gross sulphur and oil revenues
and direct operating expenses (see Note 1) and are not intended to be a complete
presentation of the revenues and expenses of the Contributed Assets.
 
    In our opinion, the statement referred to above presents fairly, in all
material respects, the gross sulphur and oil revenues and direct operating
expenses of the IGL Transferred Businesses for the year ended December 31, 1996
in conformity with generally accepted accounting principles.

    The following statement of gross sulphur and oil revenues and direct
operating expenses of the assets to be acquired (IGL Transferred Businesses) by
Freeport-McMoRan Sulphur Inc. ("Freeport Sulphur") for the year ended December
31, 1996 have been audited by Arthur Andersen LLP, independent public
accountants, as set forth in their accompanying report. The statement is
presented to provide historical data about the IGL Transferred Businesses and
may not be indicative of future results of operations of the IGL Transferred
Businesses.
 
    Separate financial statements for the IGL Transferred Businesses have never
been prepared. Depreciation, depletion and amortization has not been included
because the historical expenses incurred by the predecessor owner may not be
comparable to amounts to be incurred by Freeport Sulphur in future periods.
Further, it is not possible to make a practicable or objective determination of
the portion of general or administrative expenses or other indirect expenses
which were attributable to the IGL Transferred Businesses and any such
allocation would not be indicative of the level of such expenses to be incurred
in the future. In addition, a provision for income taxes has not been included
because the tax position of the predecessor owner will not affect Freeport
Sulphur's future tax provisions.

    BACKGROUND.  On August 26, 1997, IMC Global Inc. ("IGL") and
Freeport-McMoRan Inc. ("FTX") executed a definitive agreement for FTX to merge
with and into IGL (the "Merger"). The terms of the Merger provide that each
share of FTX common stock will be converted into the right to receive (i) 0.90
of a share of IGL common stock, (ii) one-third of a warrant exercisable for a
share of IGL common stock and (iii) a proportionate number of shares of a newly
formed company (Freeport-McMoRan Sulphur Inc.) that would be held by FTX
immediately prior to consummation of the Merger. Completion of the Merger is
subject to, among other things, approval of the definitive merger agreement by
the IGL and FTX shareholders and the expiration or early termination of the
waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976
(early termination having been granted). Both companies expect the Merger to be
completed by the end of 1997.
 
    In connection with the Merger, Freeport-McMoRan Resource Partners, Limited
Partnership, a Delaware limited partnership that is 51.6% owned by FTX ("FRP"),
will contribute to Freeport-McMoRan Sulphur Inc. ("Freeport Sulphur"), a newly
formed subsidiary of FRP, certain assets and liabilities described below and the
shares of Freeport Sulphur will be distributed to the FRP unitholders, including
FTX. FTX will then distribute its Freeport Sulphur shares to its stockholders as
part of the Merger consideration.
 
    Among the assets that will be contributed by FRP to Freeport Sulphur is
FRP's 58.3% interest in the Main Pass sulphur and oil joint venture (the "Main
Pass Joint Venture") in which IGL also has a 25% interest. The Main Pass Joint
Venture is primarily a sulphur mining operation, with the related oil deposit
being located in the same caprock containing the sulphur reserves.
 
    Immediately prior to the Merger, IGL will transfer its 25% interest in the
Main Pass Joint Venture to FRP (the "IGL Transferred Businesses"). FRP will then
contribute to Freeport Sulphur the IGL Transferred Businesses, and the FRP
Transferred Businesses; including FRP's interest in the Main Pass Joint Venture,
FRP's Culberson sulphur mine in West Texas (acquired from Pennzoil Company in
1995) and various related sulphur terminaling and transportation assets in the
Gulf Coast area.
 
    BASIS OF PRESENTATION.  The accompanying statement of gross sulphur and oil
revenues and direct operating expenses relates to the interests in IGL's
producing sulphur and oil properties described above and may not be
representative of future operations. The statement does not include federal and
state income taxes, interest, depreciation, depletion and amortization or
corporate general and administrative expenses because such amounts have
historically not been allocated to the IGL Transferred Businesses or such
amounts would not be indicative of those expenses which would be incurred by
Freeport Sulphur. The statement includes gross sulphur and oil revenues and
direct operating and production expenses, including production and ad valorem
taxes, for the entire periods presented.
 
    With respect to Main Pass sulphur production, IGL takes its share of sulphur
in kind and sells such production under a long-term contract to the IMC-Agrico
Joint Venture (IMC-Agrico), a chemical fertilizer producer jointly owned by IGL
and FRP. The contract price paid by IMC-Agrico for approximately the first
500,000 tons is based on a fixed premium over the per ton weighted average cost
of IGL's purchases of sulphur on behalf of IMC-Agrico under other long-term
supply contracts and tons sold in excess of that amount exclude the fixed
premium.
 
   
    The unaudited statement of gross sulphur and oil revenues and direct
operating expenses for the nine-month period ended September 30, 1997, in the
opinion of management, was prepared on a basis consistent with the audited
statement of gross sulphur and oil revenues and direct operating expenses and

includes all adjustments (which includes normal recurring adjustments) necessary
to present fairly the gross sulphur and oil revenues and direct operating and
production expenses for this interim period and may not be indicative of future
revenues and expenses.
 
2.  SUPPLEMENTAL INFORMATION ON SULPHUR AND OIL RESERVES (UNAUDITED)
 
    Proved and probable sulphur mineral reserves at December 31, 1996 totaled
16.6 million long tons which are subject to a 12.5 percent royalty based on net
mine revenues.
 
    The supplementary oil reserve information presented below is prepared in
accordance with requirements prescribed by the Financial Accounting Standards
Board. Proved oil reserves at December 31, 1996, have been estimated by
independent petroleum engineers in accordance with guidelines established by the
Securities and Exchange Commission (SEC). There are numerous uncertainties
inherent in estimating quantities of proved reserves and in projecting the
future rates of production and timing of development expenditures. Thus, the
following reserve estimates, which relate to reserves attributable to the IGL
Transferred Businesses, are based upon existing economic and operating
conditions; they are only estimates and should not be construed as being exact.
The reserves related to the IGL Transferred Businesses are located in offshore
United States waters. Oil, including condensate and plant products, is stated in
thousands of barrels. An analysis of the estimated changes in quantities of
proved oil reserves of the IGL Transferred Businesses for the year ended
December 31, 1996 is shown below.

    Subsequent to December 31, 1996, proved undeveloped reserve estimates were
revised downward by approximately 0.5 million barrels to reflect recent drilling
results.
 
    The standardized measure of discounted future net cash flows and changes
therein relating to the proved oil reserves of the IGL Transferred Businesses
were computed using reserve valuations based on regulations prescribed by the

    Because the tax position of the predecessor owner will not affect Freeport
Sulphur's future tax provisions, no deductions for future income taxes have been
made above. Oil prices have declined subsequent to December 31, 1996. The future

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
    
 
    Section 145 of the Delaware General Corporation Law (the "DGCL") provides
that a corporation may limit the liability of and indemnify its directors and
officers against liability in a variety of circumstances. In accordance with the
DGCL, the Company's Certificate of Incorporation contains provisions eliminating
the personal liability of the directors except for liability for (a) a breach of
his or her duty of loyalty to the Company or to its stockholders, (b) acts or
omissions not in good faith or that involve intentional misconduct or a knowing
violation of law, (c) dividends or stock repurchases or redemptions that are
unlawful under Delaware law and (d) any transaction from which he or she
receives an improper personal benefit. In addition, the Company's By-laws
require the Company to indemnify its officers and directors against expenses and
costs, judgments, settlements and fines incurred in the defense of any claim,
including any claim brought by or in the right of the Company, to which they
were made parties by reason of being or having been officers or directors.

ITEM 17.  UNDERTAKINGS
 
    Insofar as indemnification for liabilities arising under the 1933 Act may be
permitted to directors, officers and controlling persons of the Registrant
pursuant to the provisions described in Item 14 above, or otherwise, the
Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the 1933 Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the 1933 Act and will be governed by the final
adjudication of such issue.

way that the obtaining of any Consents or approvals or the making of any filings
or applications contemplated by this Agreement will satisfy the provisions of
any or all applicable agreements or the requirements of any or all applicable
laws or judgments, it being agreed and understood that except for the obligation
of FTX, FRP and their Affiliates under Section 3.01(b) and 3.05(b) the Company
shall bear the economic and legal risk that any necessary consents or approvals
are not obtained or that any requirements of law or judgments are not complied
with. 

     Section 3.07.  USE OF NAME "FREEPORT SULPHUR COMPANY".  FTX and FRP consent
to the use by the Company of the name "Freeport Sulphur Company".

     Section 3.08.  RIGHT TO AUDIT.  FTX and its successor shall have the right
to audit all amounts in respect of Section 3.01(a)(vi) and (vii) to insure that

Assets by the giving of written notice to the Company within 30 days of the
Distribution Date.

     Section 3.09.  ADMINISTRATION OF INSURANCE POLICIES.  FTX, FRP and the
Company agree to cooperate with each other with respect to the processing of any
claims that are covered by any insurance policy in existence prior to the
Distribution Date.  The parties agree to execute an agreement pursuant to which
FM Services will administer insurance claims on behalf of FTX, FRP, the Company,
certain other Persons that are also beneficiaries of insurance policies covering
periods prior to the Effective Time and their respective Affiliates.  Among
other things, this agreement will provide that (a) FTX and FM Services will
continue to own those insurance policies that each of FTX and FM Services owns
at the Effective Time; (b) FM Services will administer all claims made (whether
before or after the Effective Time) under any policies owned by FTX and FM
Services at the Effective Time subject to the payment by all such beneficiaries
of the reasonable costs of FM Services to handle such matters with such
administration activities being subject to the direction of the respective
beneficiaries and their respective successors and/or assigns in accordance with
criteria typical to and customary with third party administration relationships
common in the industry; (c) FTX will transfer to FM Services or the appropriate
Person any accruals for the self-insured portion or deductible relating to any
claims or threatened claims against such Person other than FTX or FRP covered by
one or more insurance policies owned by FTX, as funds are required to meet those
obligations; and (d) the FM Services insurance policies under which FTX is a
beneficiary shall be supplemented with the following endorsement or an
endorsement that is otherwise reasonably acceptable to IMC Global Inc. and the
parties hereto:  "In consideration of premiums paid, it is understood and agreed
that IMC Global Inc. is an Additional Named Insured under this policy as their
interests may appear with respect to all operations of FTX which have been
acquired by IMC Global Inc. as of (date of merger)" for all losses covered by
the policy and occurring prior to the Effective Time of the merger. 

     Section 3.10.  OTHER ACTIONS OF THE COMPANY.  In addition to the specific
actions required to be taken by virtue of this Agreement, the Company agrees to
take all such lawful action with respect to the Company Common Stock as may be
necessary or appropriate in order to comply with legal requirements applicable
to the Distribution, the Merger or any of the other transactions contemplated by
this Agreement.

     Section 3.11.  POST-CLOSING OBLIGATIONS.  

          (a)  In the event that any party to this Agreement (the "Paying
Party") makes any payment in respect of any obligation for which any other
Person (the "Obligated Party") is obligated pursuant to this Agreement or
otherwise, the Obligated Party shall reimburse the Paying Party within 30 days
of receiving a written request from the Paying Party containing reasonable
evidence that the Paying Party has made such payment.  To the extent that any
pay period for any Transferred Employees (as such term is defined in the
Employee Benefits Agreement) spans a period of time which includes days both
before and after the Effective Time, the obligation of FTX and the Company for
such amounts shall be prorated, with FTX being obligated to pay an amount equal
to the total employee pay check for such pay period (including all withholdings)
times a fraction the numerator of which is the number of days in the pay period
prior to the date of the Effective Time and the denominator of which is the
total number of days in the pay period, and the Company being 

                                  -18-
<PAGE>

obligated to pay an amount equal to the total pay check for such pay period 
(including all withholdings) times a fraction the numerator of which is the 
number of days during the pay period on or after the Effective Time and the 
denominator of which is the total number of days in the pay period.  The 
Company shall make the payment to the Transferred Employees for such pay 
period and FTX shall reimburse the Company for its pro rata portion thereof 
in accordance with the procedures set forth in the immediately preceding 
sentence.

                                   ARTICLE IV
                   EMPLOYEES, EMPLOYEE BENEFIT PLANS AND TAXES

     Section 4.01.  TERMINATION OF EMPLOYMENT; EMPLOYEES BENEFITS AGREEMENT. 
FTX, FRP and Company agree to execute and be bound by the Employee Benefits
Agreement.  Immediately prior to the Effective Time, FTX and FRP shall terminate
any of their remaining employees who are actively at work at the Effective Time
that have not been transferred to the Company or have not previously left the
employ of FTX.  FTX and FRP acknowledge that the Company intends to offer
employment to many of the employees currently employed by FTX and FRP.

     Section 4.02.  WORK RELATED CLAIMS.  From and after the Distribution Date,
FTX and FRP shall remain solely responsible for any and all Liabilities to or in
respect of any employee, excluding any Transferred Employee (as defined in the
Employee Benefits Agreement), relating to or arising in connection with any and
all claims under applicable workmen's compensation laws, the Jones Act, 46
U.S.C. Section 688, the Longshore and Harbor Workers' Compensation Act, 33
U.S.C. Section 901, ET SEQ. or under similar laws, or arising in connection with
any occupational injury or disease, in each case occurring or existing on or
prior to the Distribution Date.  FTX and FRP will comply with and shall be
responsible for all Liabilities incurred in connection with noncompliance with
the Worker Adjustment and Retraining Notification Act of 1989, 29 U.S.C. Section
2101 ET SEQ., as amended with respect to the respective employees of each such
company.  

     Section 4.03.  EMPLOYMENT TAXES.  (a) FTX and Company will (i) treat
Company as a "successor employer" and FTX as a "predecessor" within the meaning
of Sections 3121(a)(1) and 3306(b)(1) of the Code, with respect to transferred
employees who are employed by the Company for purposes of Taxes imposed under
the United States Federal Unemployment Tax Act (FICA) or the United States
Federal Insurance Contribution Act (FUTA) and (ii) cooperate with each other to
avoid, to the extent possible, the filing of more than one Internal Revenue
Service form W-2 with respect to each such transferred employee for the calendar
year within which the Distribution Date occurs.

                                    ARTICLE V
                                 INDEMNIFICATION

     Section 5.01   (a)  BY FTX AND FRP.  FTX and FRP jointly and severally
covenant and agree (except in the case of subsection (vii) of this Section
4.2(a), in which case FTX individually covenants and agrees) to defend,
indemnify and hold harmless the Company, its officers, directors, 

                                  -19-
<PAGE>

and those entities that are Affiliates of the Company immediately following 
the Effective Time and each of the heirs, executors, successors, and assigns 
of any of the foregoing (collectively the "COMPANY INDEMNITEES"), from and 
against, and pay or reimburse the Company Indemnitees for, any and all 
claims, liabilities, obligations, losses, fines, costs, royalties, penalties, 
proceedings, deficiencies, or damages (whether absolute or accrued, 
conditional or otherwise, and whether or not resulting from third party 
claims), including out-of-pocket expenses and reasonable attorneys' and 
accountants' fees incurred in the investigation or defense of any of the same 
or asserting any of their respective rights hereunder (collectively 
"LOSSES"), to the extent resulting from or arising out of:  (i) any failure 
of FTX, FRP or any of their Affiliates to perform any covenant or agreement 
hereunder or fulfill any other obligation in respect hereof; (ii) any 
Excluded Liabilities; (iii) any Excluded Assets; (iv) any and all Taxes of 
FTX, FRP and/or their respective Affiliates immediately following the 
Effective Time relating to or arising out of the Transferred Businesses or 
any Transferred Asset accruing, or with respect to any event or time period 
occurring, at or prior to the Distribution Date and which FTX or FRP has 
assumed responsibility pursuant to the provisions of this Agreement; (v) any 
and all Liabilities in respect of employees of FTX, FRP or any of their 
Affiliates prior to or as of the Distribution Date, except to the extent 
expressly assumed by the Company pursuant to the Employee Benefits Agreement; 
(vi) any failure of FTX, FRP or any of their Affiliates to comply with 
applicable bulk sales laws (in consideration of which indemnification 
obligation the Company hereby waives compliance by FRP, FTX and their 
Affiliates with applicable bulk sales laws); or (vii) any breach of any 
warranty or inaccuracy of any representation of FTX or FRP contained herein, 
except, to the extent such Losses result from or arise out of the Assumed 
Liabilities or constitute Losses for which the Company is required to 
indemnify the FRP Indemnitees under Section 5.01(b).

     (b)  BY COMPANY.  The Company covenants and agrees to defend, indemnify,
and hold harmless FRP and FTX and their respective officers, directors,
employees, agents, advisors, representatives, contractors, subcontractors and
those entities that are Affiliates of FRP and FTX immediately following the
Effective Time and each of the heirs, executors, successors, and assigns of any
of the foregoing (collectively, the "FRP INDEMNITEES") from and against any and
all Losses to the extent resulting from or arising out of:  (i) any failure of
the Company to perform any covenant or agreement hereunder or fulfill any other
obligation in respect hereof; (ii) any Assumed Liabilities or Transferred
Assets; (iii) any and all Taxes relating to or arising out of the Transferred
Businesses or any Transferred Asset accruing, or with respect to any event or
time period occurring, subsequent to the Distribution Date or in respect of
which the Company has assumed responsibility pursuant to the provisions of this
Agreement; (iv) any Liabilities in respect of employees of FTX, FRP or their
Affiliates to the extent expressly assumed by the Company pursuant to the
Employee Benefits Agreement; except, to the extent such Losses result from or
arise out of the Excluded Liabilities or constitute Losses for which FRP and/or
FTX are required to indemnify Company Indemnitees under Section 5.01(a); or (v)
any breach of any warranty or inaccuracy of any representation of the Company
contained herein.

     (c)  ADJUSTMENTS TO INDEMNIFICATION PAYMENTS.  Any payment made by FRP
and/or FTX to the Company Indemnitees, on the 

                                  -20-
<PAGE>

one hand, or by the Company to the FRP Indemnitees, on the other hand, 
pursuant to this Article V in respect of any claim shall be net of any 
insurance proceeds received by the Indemnified Party in respect of such 
claim.  The Indemnified Party shall use its reasonable efforts to pursue 
insurance claims relating to any claim for which it is seeking 
indemnification pursuant to this Section 5.01; PROVIDED that the Indemnified 
Party shall not be obligated to pursue an insurance claim if the Indemnified 
Party in its reasonable judgment believes the cost of pursing such an 
insurance claim exceed the value of the claim for which the Indemnified Party 
is seeking indemnification. If any Indemnitee shall have received the payment 
required by this Agreement from an Indemnifying Party in respect of an 
indemnifiable Loss and shall subsequently receive insurance proceeds, then 
such Indemnitee shall pay to such Indemnifying Party a sum equal to the 
amount of such insurance proceeds. 

     (d)  INDEMNIFICATION PROCEDURES.  In the case of any claim for 
indemnification pursuant to this Agreement by a party entitled to
indemnification under this Agreement (the "INDEMNIFIED PARTY"), notice shall be
given by the Indemnified Party to the party required to provide indemnification
(the "INDEMNIFYING PARTY") promptly after such Indemnified Party has actual
knowledge of any claim as to which indemnity may be sought, and the Indemnified
Party shall permit the Indemnifying Party (at the expense of such Indemnifying
Party) to assume the defense of any claim or litigation resulting therefrom,
PROVIDED that (i) the Indemnified Party may participate in such defense at such
Indemnified Party's expense, and (ii) the omission by any Indemnified Party to
give notice as provided herein shall not relieve the Indemnifying Party of its
indemnification obligations under this Agreement except to the extent that such
omission results in a failure of actual notice to the Indemnifying Party and
such Indemnifying Party is materially damaged as a result of such failure to
give notice.  Except with the prior written consent of the Indemnified Party, no
Indemnifying Party, in the defense of any such claim or litigation, shall
consent to the entry of any judgment or enter into any settlement that provides
for injunctive or other non-monetary relief affecting the Indemnified Party
where it does not include as an unconditional term thereof the giving by each
claimant or plaintiff to such Indemnified Party of a release from all Liability
with respect to such claim or litigation.  Unless an Indemnifying Party elects
not to assume the defense of or to seek to settle or compromise a third party
claim, such Indemnifying Party shall not be liable to such Indemnitee under this
Article V for any legal or other expenses subsequently incurred by such
Indemnitee in connection with the defense thereof; and in the event that the
Indemnifying Party does not accept the defense of any matter as above provided,
the Indemnified Party shall have the full right to defend against any such claim
or demand and shall be entitled to settle or agree to pay in full such claim or
demand.  In any event, the Indemnifying Party and the Indemnified Party shall
cooperate in the defense of any claim or litigation subject to this Section 5.01
and the records of each shall be available to the other with respect to such
defense.  Upon written demand of an Indemnitee, an Indemnifying Party shall
reimburse such Indemnitee for all direct, out of pocket Losses reasonably
incurred by it in connection with investigating or defending any third party
claim at the request of the Indemnifying Party in advance of its final
disposition; PROVIDED, that such reimbursement need be made only upon delivery
to the Indemnifying Party of an undertaking by such Indemnitee to repay all
amounts so reimbursed or advanced if it shall ultimately be determined that such
Indemnitee is not entitled to indemnification under this Article V or otherwise.


                                  -21-

     (e)  All claims for indemnification under this Article V shall survive
indefinitely after the Effective Time.

                                   INFORMATION

     Section 6.01.  ACCESS TO INFORMATION.  From and after the date hereof, each
party shall afford each other party and its accountants, counsel and other

to give access to persons or firms possessing information) and duplicating
rights during normal business hours to all records, books, contracts,
instruments, computer data and other data and information in such party's
possession relating to the business and affairs of such other party (other than
data and information subject to any attorney/client or other privilege or
otherwise required to be kept confidential pursuant to binding agreements),
insofar as such access is reasonably required by such other party including,
without limitation, for audit, accounting and litigation purposes, as well as
for purposes of fulfilling disclosure and reporting obligations.

     Section 6.02.  LITIGATION COOPERATION.  Each party shall use reasonable
efforts to make available to each other party, upon written request, the
officers, directors, employees and agents of such parties and those entities
that are Affiliates immediately following the Effective Time as witnesses to the
extent that such persons may reasonably be required in connection with any
Action arising out of the business of the Company and its predecessors in which
the requesting party may from time to time be involved.

     Section 6.03.  REIMBURSEMENT.  Each party providing information or
witnesses under Sections 6.01 or 6.02 to any other party shall be entitled to
receive from the recipient, upon the presentation of invoices therefor, payment
for all reasonable, direct, out-of-pocket costs and expenses as may be
reasonably incurred in providing such information or witnesses.

     Section 6.04.  RETENTION OF RECORDS.  Except as otherwise required by law
or agreed to in writing, each party shall preserve and retain all information
relating to each other party's business throughout the term of the and for a
period of seven (7) years thereafter.

benefits, rights or remedies, provided, however, that notwithstanding anything

policy, all other terms, provisions and conditions of this Agreement shall

substance of the transactions contemplated hereby are not affected in any manner
materially adverse to any party hereto.  Upon any determination that any term or
other provision hereof is invalid, illegal or incapable of being enforced, the
parties hereto shall negotiate in good faith to modify this Agreement so as to

acceptable manner in order that the transactions contemplated by this Agreement
may be consummated as originally contemplated to the fullest extent possible.

to or redelivery of such instruments of conveyance, assumption and assignment 
that may be necessary to vest in the Assignee title to or other applicable 
rights in the Assets and (ii) the delivery of originals of stock certificates

Inc. (which will become the indirect parent of IMCAC following the Merger)  have
previously executed a letter agreement clarifying the provisions of Section III

"As-is, Where-is," except for rights or actions in warranty against predecessors

judgments, it being agreed and understood that Assignee shall bear the economic
and legal risk that any necessary Consents are not obtained or that any
requirements

          of the Board of Directors, and the distinctive designation thereof;

               (2)  the dividend rights of such series, the preferences, if any,

                                STOCKHOLDER ACTION

     Action shall be taken by the stockholders only at an annual or special
meeting of stockholders and may not be effected by any written consent of such
holders.

                                   ARTICLE VII
                               BOARD OF DIRECTORS

     1.   POWERS.  All of the powers of the Corporation are hereby conferred
upon the Board of Directors of the Corporation, insofar as such powers may be
lawfully vested by this Certificate of Incorporation in the Board of Directors. 
In furtherance and not in limitation of those powers, the Board of Directors
shall have the power to make, adopt, alter, amend and repeal from time to time
the Corporation's Bylaws, subject to the provisions of Article X, section 2.

     2.   NUMBER OF DIRECTORS.  Subject to the restriction that the number of
directors shall not be less than the number required by the DGCL, the number of
directors may be fixed from time to time pursuant to the Corporation's Bylaws;
provided, however, that the number of directors shall not be reduced so as to
shorten the term of any director at the time in office.

     3.   CLASSIFICATION.  The members of the Board of Directors, other than
those who may be elected by the holders of any one or more series of Preferred
Stock voting separately, shall be classified, with respect to the term during
which they shall hold office, into three classes, designated Class I, II and
III, as nearly equal in number as possible.  Any increase or decrease in the
number of directors shall be apportioned by the Board of Directors so that all
classes of directors shall be as nearly equal in number as possible.  At each
annual meeting of stockholders, directors chosen to succeed those whose terms
then expire shall be elected to hold office for a term expiring at the annual
meeting of stockholders held in the third year following the year of their
election and until their successors are duly elected and qualified.

                                       3

<PAGE>

     4.   VACANCIES.  Subject to any requirements of law and the rights of any
class or series of Capital Stock having a preference over the Common Stock as to
dividends or upon liquidation, and except as provided in Article VII, section 6,
any vacancy on the Board of Directors (including any vacancy resulting from an
increase in the authorized number of directors or from a failure of the
stockholders to elect the full number of authorized directors) may,
notwithstanding any resulting absence of a quorum of directors, be filled only
by the Board of Directors, acting by vote of both (a) a majority of the
directors then in office and (b) a majority of all the Continuing Directors,
voting as a separate group, and any director so appointed shall serve until the
next stockholders' meeting held for the election of directors of the class to
which such director shall have been appointed and until his successor is duly
elected and qualified.

     5.   REMOVAL.  Subject to Article VII, section 6, and notwithstanding any
other provisions of this Certificate of Incorporation or the Corporation's
Bylaws, any director or the entire Board of Directors may be removed at any
time, but only for cause involving fraud or a violation of the duty of loyalty
as determined by a final judgment of a court of competent jurisdiction, and only
by the affirmative vote of holders of not less than 80% of the Voting Stock,
voting together as a single class, at a stockholders' meeting called for such
purpose.  At the same meeting in which the stockholders remove one or more
directors, the stockholders may elect one or more successors for the unexpired
term or terms of the director or directors removed.  Except as set forth in this
Article VII, section 5, directors shall not be subject to removal.

     6.   DIRECTORS ELECTED BY PREFERRED STOCKHOLDERS.  Notwithstanding anything
in this Certificate of Incorporation to the contrary, whenever the holders of
any one or more series of Preferred Stock shall have the right, voting
separately as a class, to elect one or more directors of the Corporation, the
provisions of this Certificate of Incorporation (as amended from time to time)
fixing the rights and preferences of such Preferred Stock shall govern with
respect to the nomination, election, term, removal, vacancies or other related
matters with respect to such directors.

                                  ARTICLE VIII

Combination (regardless of whether such proxy or information statement is
required pursuant to such act).

     2.   EXCEPTIONS TO SUPERMAJORITY VOTE REQUIREMENTS.  If all conditions
specified in either of paragraphs (a) or (b) below are met, the provisions of
Article VIII, section 1, shall not be applicable to any Business Combination,

               same class or series of voting stock on the first day in such
               two-year period on which the Interested Stockholder acquired any
               shares or the same class or series of Voting Stock.

          outstanding stock shall receive the consideration in cash or in the
          same form as the Interested Stockholder has previously paid for shares
          of the same class or series of stock.  If the Interested Stockholder
          has paid for shares of any class of stock with varying forms of
          consideration, the form of consideration for such class of stock shall
          be either in cash or the form used to acquire the largest number of
          shares of such class or series of stock previously acquired by it.  In
          making any price calculation under paragraph (b) of Article VIII,
          section 2, appropriate adjustments shall be made to reflect any
          reclassification or stock split (including any reverse stock split),
          stock dividend, recapitalization, reorganization or any similar
          transaction which has the effect or increasing or reducing the number
          of outstanding shares of stock.  

               (4)  After the Interested Stockholder has become an Interested
          Stockholder and prior to the consummation of such Business
          Combination:

                    (A)  there shall have been no failure to declare and pay at
               the regular date therefor any full periodic dividends, whether or
               not cumulative, on any outstanding Preferred Stock of the
               Corporation or other Capital Stock 

                                       7

<PAGE>

               entitled to a preference over the Common Stock as to dividends 
               or upon liquidation;

                    (B)  there shall have been no reduction in the annual rate
               of dividends paid on the Common Stock, except as necessary to
               reflect any subdivision of the Common Stock, and no failure to
               increase the annual rate of dividends as necessary to reflect any
               reclassification (including any reverse stock split),
               recapitalization, reorganization or other similar transaction
               which has the effect of reducing the number of outstanding shares
               of Common Stock; and

                    (C)  the Interested Stockholder did not become the
               Beneficial Owner of any additional shares of stock of the
               Corporation except as part of the transaction that resulted in
               such Interested Stockholder becoming an Interested Stockholder or
               by virtue of proportionate stock splits or stock dividends.

          The provisions of clauses (A) and (B) immediately preceding shall not
          apply if no Interested Stockholder or any Affiliate or Associate
          thereof voted as a director of the Corporation in favor of foregoing
          or reducing dividends in the manner specified in such clauses and the
          Interested Stockholder, within ten days after any such act or failure
          to act that resulted in such loss or diminution of dividends, notifies
          the Board of Directors of the Corporation in writing that the
          Interested Stockholder disapproves thereof and requests in good faith
          that the Board of Directors rectify such act or failure to act.

               (5)  After the Interested Stockholder has become an Interested
          Stockholder, the Interested Stockholder shall not have received the
          benefit, directly or indirectly, except proportionately as a
          stockholder, of any loans, advances, guarantees, pledges or other
          financial assistance provided by the Corporation or any Subsidiary,
          whether in anticipation of or in connection with such Business
          Combination or otherwise.

     3.   DETERMINATIONS.  For the purpose of this Article VIII, so long as
Continuing Directors constitute at least a majority of the entire Board of

Business Combination (including the power to determine in good faith the book
value or market value of the assets of the Corporation or any Subsidiary) or is
a transaction with or for the benefit of an Interested Stockholder, (e) whether
any of the events referred to in paragraph (b)(4) of Article VIII, section 2,
have occurred, and (f) such other matters with respect to which a determination
is required under this Article VIII.  All such good faith determinations by the
Board of Directors shall

     notice of a proposal that may properly be brought before the meeting, a 
     proposal sufficient notice of which is subsequently received by the 
     Secretary and that is substantively duplicative of the first proposal 
     shall not be deemed properly brought before the meeting.  If in the 
     judgment of the Board of Directors a proposal deals with substantially 
     the same subject matter as a prior proposal submitted to stockholders 
     at a meeting held within the preceding five years, it shall not be 
     properly brought before any meeting held within three years after the 
     latest such previous submission if (A) the proposal was submitted at 
     only one meeting during such preceding period and it received 
     affirmative votes representing less than 3% of the total number of 
     votes cast in regard thereto, (B) the proposal was submitted at only 
     two meetings during such preceding period and it received at the time 
     of its second submission affirmative votes representing less than 6% of 
     the total number of votes cast in regard thereto, or (C) the proposal 
     was submitted at three or more meetings during such preceding period 
     and it received at the time of its latest submission affirmative votes 
     representing less than 10% of the total number of votes cast in regard 
     thereto.

              (ii)  Notwithstanding compliance with all of the procedures 
     set forth above in this Section, no proposal shall be deemed to be 
     properly brought before a meeting of stockholders if, in the judgment 
     of the Board of Directors, it is not a proper subject for action by 
     stockholders under Delaware Law.

          (g)  At the meeting of stockholders, the chairman shall declare out 
of order and disregard any nomination or other matter that is not presented 
in accordance with the foregoing procedures or that is otherwise contrary to 
the foregoing terms and conditions.

registered in the name of each stockholder.  Such list shall be open to the 
examination of any stockholder, for any purpose germane to the meeting, 
during ordinary business hours, for a period of at least ten days prior to 
the meeting, either at a place within the city where the meeting is to be 
held, which place shall be specified in the notice of the meeting, or, if not

voted upon at any stockholders' meeting, the holders of a majority of the 
outstanding shares of each class of Capital Stock, or series thereof, 
entitled to vote thereon, present in person or represented by proxy, shall 
constitute a quorum, provided that two or more classes or series shall be 
considered a single class if the holders thereof are entitled to vote 
together as a single class with respect to such matter.  If, however, a 
quorum shall not be present or represented at any meeting of the stockholders

holders of any class of Capital Stock or series thereof entitled to vote 
thereat (or with respect to any such matter), present in person or 
represented by proxy, shall have the power to adjourn the meeting (or the 
vote upon such matter, without prejudice to the right of the stockholders to 
vote upon any matter as to which a quorum does exist) from time to time, 
without notice other than announcement at the meeting, until a quorum shall

record date is fixed for the adjourned meeting, a notice of the adjourned 
meeting shall be given to each stockholder of record entitled to vote at the 
meeting (or with respect to such matter).

considered at any meeting of stockholders, the vote of the holders of a 
majority of the Voting Stock shall decide such matter, unless the matter is 
one upon which by express provision of law, the Certificate of Incorporation 
or these By-laws, a different vote is required, in which case such express 
provision shall govern and control the decision of such matter.

     2.8  VOTING RIGHTS OF STOCKHOLDERS.  Unless otherwise provided in the 
Certificate of Incorporation, each stockholder shall at every meeting of the 
stockholders be entitled to one vote in person or by proxy for each share of

Stock on any matter, every reference in these By-laws to a majority or other 
proportion of Voting Stock shall refer to such majority or other proportion 
of the total votes accorded such shares of stock.

          (b)  Execution of a proxy may be accomplished by a stockholder or 
his or her authorized officer, director, employee or agent signing such 
writing or causing his or her signature to be affixed to such writing by any 
reasonable means including, without limitation, by facsimile signature.  A 
stockholder may authorize another person or persons to act for him as proxy 
by transmitting or authorizing the transmission of a telegram, cablegram, or 
other means of electronic transmission to the person who will be the holder 
of the proxy or to a proxy solicitation firm, proxy support service

holder of the proxy to receive such transmission, provided that any such 
telegram, cablegram or other means of electronic transmission must either set 
forth or be submitted with information from which it can be determined that 
the telegram, cablegram or other electronic transmission was authorized by 
the stockholder.  If it is determined that such telegrams, cablegrams or 
other electronic transmissions are valid, the inspectors shall specify the 
information upon which they relied.

          (c)  Any copy, facsimile telecommunication or other reliable 
reproduction of the writing or transmission may be substituted or used in 
lieu of the original writing or transmission for any and all purposes for 
which the original writing or transmission could be used, provided that such 
copy, facsimile telecommunication or other reproduction shall be a complete 
reproduction of the entire original writing or transmission.

          (d)  A duly executed proxy shall be irrevocable if it states that 
it is irrevocable and if, and only as long as, it is coupled with an interest 
sufficient in law to support an irrevocable power.  A stockholder may revoke 
any proxy that is not irrevocable by attending the meeting and voting in 
person or by filing an instrument in writing revoking the proxy or another 
duly executed proxy bearing a later date with the Secretary. 

     2.10 NO UNANIMOUS WRITTEN CONSENT.  Unless otherwise provided in the

adjournment a new record date is fixed for the adjourned meeting, notice of

advertise the same in such manner as it shall require and/or give the 
Corporation a bond in such sum as it may direct as indemnity against any 
claim that may be made against the Corporation with respect to the 
certificate alleged to have been lost, stolen or destroyed.

     8.6  TRANSFER OF STOCK.  Upon surrender to the Corporation or the 
transfer agent of a certificate for shares duly endorsed or accompanied by 
proper evidence of succession, assignation or authority to transfer, it shall 
be the duty of the Corporation to issue a new certificate to the person 
entitled thereto, cancel the old certificate and record the transaction upon 
its books. Upon receipt of proper transfer instructions from the registered 
owner of uncertificated shares such uncertificated shares shall be cancelled 
and issuance of new equivalent uncertificated shares or certificated shares 
shall be made to the person entitled thereto and the transaction shall be 
recorded upon the books of the Corporation.

     8.7  REGISTERED STOCKHOLDERS.  Except as otherwise provided by law, the 
Corporation, and its directors, officers and agents, may recognize and treat 
a person registered on its records as the owner of shares, as the owner in 
fact thereof for all purposes, and as the person exclusively entitled to have 
and to exercise all rights and privileges incident to the ownership of such 
shares, and rights

                                      12

under this Section 8.7 shall not be affected by any actual or constructive 
notice that the Corporation, or any of its directors, officers or agents, may 
have to the contrary.


                                   SECTION 9
                                INDEMNIFICATION

     9.1  INDEMNITY.  (a) Except with respect to an action or Claim (other 
than as authorized in Section 9.2) commenced by an Indemnitee against the 
Corporation or by an Indemnitee as a derivative action by or in the right of 
the Corporation that has not been authorized by the Board, the Corporation 
shall indemnify, defend and hold harmless any Indemnitee against Expenses 
reasonably incurred or suffered in connection with any Claim against 
Indemnitee, whether the basis of such Claim is alleged action or inaction in 
an official capacity as Indemnitee or in any other capacity while serving as 
an Indemnitee (including appearances as a witness or in connection with 
giving testimony or evidence), if:

          (i)  the Indemnitee is successful in his defense of the Claim on 
     the merits or otherwise, or

         (ii)  the Indemnitee has been found by the Determining Body to have 
     met the Standard of Conduct (as determined in accordance with the 
     procedures set forth in this Section 9.1), provided that no 
     indemnification shall be made in respect of any Claim by or in the 
     right of the Corporation as to which Indemnitee shall have been 
     adjudicated in a final judgment to be liable to the Corporation, 
     unless, and only to the extent that the court in which such Claim was 
     brought shall determine upon application that, despite such 
     adjudication of liability but in view of all the circumstances of the 
     case, Indemnitee is fairly and reasonably entitled to indemnity for 
     such Expenses which the court shall deem proper.

          (b)  For purposes of this Section 9, the "Standard of Conduct" is 
met when conduct by an Indemnitee with respect to which a Claim is asserted 
was conduct performed in good faith which he reasonably believed to be in, or 
not opposed to, the best interest of the Corporation, and, in the case of a 
Claim which is a criminal action or proceeding, conduct that the Indemnitee 
had no reasonable cause to believe was unlawful.  The termination of any 
Claim by judgment, order, settlement, conviction, or upon a plea of nolo 
contendere or its equivalent, shall not, of itself, create a presumption that 
Indemnitee did not meet the Standard of Conduct.

          (c)  Promptly upon becoming aware of the existence of any Claim as 
to which Indemnitee may be indemnified hereunder, Indemnitee shall notify the 
Chief Executive Officer of the Corporation, but the failure to promptly 
notify the Chief Executive Officer shall not relieve the Corporation from any 
obligation under this Section 9.  Upon receipt of such request, the Chief 
Executive Officer shall promptly advise the members of the Board of the 
request and that the establishment of a Determining Body with respect to 
Indemnitee's request for indemnification as to the Claim will be presented at 
the next regularly scheduled meeting of the Board.  If a meeting of the Board 
is not regularly scheduled within 120 calendar days of the date the Chief 
Executive Officer receives notice of the Claim, the Chief Executive Officer 
shall cause a special meeting of the Board of Directors to be called within 
such period in accordance with the provisions of the By-laws.  After

                                      13
<PAGE>

the Determining Body has been established, the Determining Body shall inform 
the Indemnitee of the constitution of the Determining Body and Indemnitee 
shall provide the Determining Body with all facts relevant to the Claim known 
to such Indemnitee, and deliver to the Determining Body all documents 
relevant to the Claim in Indemnitee's possession.  Before the 60th day after 
its receipt from the Indemnitee of such information (the "Determination 
Date"), together with such additional information as the Determining Body may 
reasonably request of Indemnitee prior to such date (the receipt of which 
shall not begin a new 60-day period) the Determining Body shall determine 
whether or not Indemnitee has met the Standard of Conduct and shall advise 
Indemnitee of its determination.  If Indemnitee shall have supplied the 
Determining Body with all relevant information, including all additional 
information reasonably requested by the Determining Body, any failure of the 
Determining Body to make a determination by or on the Determination Date as 
to whether the Standard of Conduct was met shall be deemed to be a 
determination that the Standard of Conduct was met by Indemnitee.

          (d)  If at any time during the 60-day period ending on the 
Determination Date, Indemnitee becomes aware of any relevant facts not 
theretofore provided by him to the Determining Body, Indemnitee shall inform 
the Determining Body of such facts, unless the Determining Body has obtained 
such facts from another source.  The provision of such facts to the 
Determining Body shall not begin a new 60 day period.

          (e)  The Determining Body shall have no power to revoke a 
determination that Indemnitee met the Standard of Conduct unless Indemnitee 
(i) submits to the Determining Body at any time during the 60 days prior to 
the Determination Date fraudulent information, (ii) fails to comply with the 
provisions of Section 9.1(d), or (iii) intentionally fails to submit 
information or documents relevant to the Claim reasonably requested by the 
Determining Body prior to the Determination Date.

          (f)  In the case of any Claim not involving any threatened or 
pending criminal proceeding:

          (i)  if prior to the Determination Date the Determining Body has 
     affirmatively made a determination that Indemnitee met the Standard of 
     Conduct (not including a determination deemed to have been made by 
     inaction), the Corporation may, in its sole discretion, after notice to 
     Indemnitee, assume all responsibility for the defense of the Claim with 
     counsel satisfactory to Indemnitee (who shall not, except with the 
     written consent of Indemnitee, be counsel to the Corporation), and, in 
     any event, the Corporation and the Indemnitee each shall keep the other 
     informed as to the progress of the defense of the Claim, including 
     prompt disclosure of any proposals for settlement; provided that if the 
     Corporation is a party to the Claim and Indemnitee reasonably 
     determines that there is any conflict between the positions of the 
     Corporation and Indemnitee, with respect to the Claim or otherwise, 
     then Indemnitee shall be entitled to conduct his defense with counsel 
     of his choice at the Corporation's expense in accordance with the terms 
     and conditions of this Section 9; and provided further that Indemnitee 
     shall in any event be entitled at his expense to employ counsel chosen 
     by him to participate in the defense of the Claim; and

                                      14
<PAGE>

         (ii)  The Corporation shall not be obligated to indemnify Indemnitee 
     for any amount paid in a settlement that the Corporation has not 
     approved. The Corporation shall fairly consider any proposals by 
     Indemnitee for settlement of the Claim.  If the Corporation proposes a 
     settlement of the Claim and such settlement is acceptable to the person 
     asserting the Claim, or the Corporation believes a settlement proposed 
     by the person asserting the Claim should be accepted, it shall inform 
     Indemnitee of the terms of such proposed settlement and shall fix a 
     reasonable date by which Indemnitee shall respond.  If Indemnitee 
     agrees to such terms, he shall execute such documents as shall be 
     necessary to make final the settlement. If Indemnitee does not agree 
     with such terms, Indemnitee may proceed with the defense of the Claim 
     in any manner he chooses, provided that if Indemnitee is not successful 
     on the merits or otherwise, the Corporation's obligation to indemnify 
     such Indemnitee as to any Expenses incurred following his disagreement 
     shall be limited to the lesser of (A) the total Expenses incurred by 
     Indemnitee following his decision not to agree to such proposed 
     settlement or (B) the amount that the Corporation would have paid 
     pursuant to the terms of the proposed settlement.  

          (g)  In the case of any Claim involving a proposed, threatened or 
pending criminal proceeding, Indemnitee shall be entitled to conduct the 
defense of the Claim with counsel of his choice and to make all decisions 
with respect thereto; provided, that the Corporation shall not be obliged to 
indemnify Indemnitee for any amount paid in settlement of such a Claim unless 
the Corporation has approved such settlement.

          (h)  After notifying the Corporation of the existence of a Claim in 
accordance with Section 9.1(c), Indemnitee may from time to time request the 
Corporation to pay the Expenses (other than judgments, fines, penalties or 
amounts paid in settlement) that he incurs in pursuing a defense of the Claim 
prior to the time that the Determining Body determines whether the Standard 
of Conduct has been met.  The Disbursing Officer shall pay to Indemnitee the 
amount requested (regardless of Indemnitee's ability to repay such amount) 
upon receipt of an undertaking by or on behalf of Indemnitee to repay such 
amount along with any other amounts advanced or paid after the Determination 
Date in accordance with the provisions of this Section 9.1, if (i) the 
Determining Body determines prior to the Determination Date that Indemnitee 
did not meet the Standard of Conduct or (ii) Indemnitee is prohibited from 
being indemnified by the Corporation by virtue of the provisions of Delaware 
Law.

          (i)  After it has been determined that the Standard of Conduct has 
been met, for so long as and to the extent that the Corporation is required 
to indemnify Indemnitee under this Section 9, the provisions of Section 
9.1(h) shall continue to apply with respect to Expenses incurred after such 
time except that (i) no undertaking shall be required of Indemnitee and (ii) 
the Disbursing Officer shall pay to Indemnitee the amount of any fines, 
penalties or judgments against him that have become final and for which he is 
entitled to indemnification hereunder, and any amount of indemnification 
ordered to be paid to him by a court. 

          (j)  Any determination by the Corporation with respect to settlement 
of a Claim shall be made by the Determining Body.

                                      15
<PAGE>

          (k)  All determinations and judgments made by the Determining Body 
hereunder shall be made in good faith.

          (l)  The Corporation and Indemnitee shall keep confidential to the 
extent permitted by law and their fiduciary obligations all facts and 
determinations provided pursuant to or arising out of the operation of this 
Section 9 and the Corporation and Indemnitee shall instruct its or his agents 
and employees to do likewise.

     9.2  ENFORCEMENT.  (a) The rights provided by this Section 9 shall be 
enforceable by Indemnitee in any court of competent jurisdiction.

          (b)  If Indemnitee seeks a judicial adjudication of his rights 
under this Section 9 Indemnitee shall be entitled to recover from the 
Corporation, and shall be indemnified by the Corporation against, any and all 
Expenses actually and reasonably incurred by him in connection with such 
proceeding but only if he prevails therein.  If it shall be determined that 
Indemnitee is entitled to receive part but not all of the relief sought, then 
the Indemnitee shall be entitled to be reimbursed for all Expenses incurred 
by him in connection with such judicial adjudication if the amount to which 
he is determined to be entitled exceeds 50% of the amount of his claim.   
Otherwise, the Expenses incurred by Indemnitee in connection with such 
judicial adjudication shall be appropriately prorated.

          (c)  In any judicial proceeding described in this Section 9.2, the 
Corporation shall bear the burden of proving that Indemnitee is not entitled 
to the relief sought, even if the Determining Body prior to the Determination 
Date determined that Indemnitee failed to meet the Standard of Conduct.  If 
prior to the Determination Date the Determining Body failed to make a 
determination that Indemnitee did not meet the Standard of Conduct, it shall 
not be a defense to such suit that Indemnitee did not meet the Standard of 
Conduct.

     9.3  REFORMATION.   If any provision of this Section 9 is determined by 
a court having jurisdiction over the matter to violate or conflict with 
applicable law, the court shall be empowered to modify or reform such 
provision so that, as modified or reformed, such provision provides the 
maximum indemnification permitted by Delaware Law, and such provision, as so 
modified or reformed, and the balance of this Section 9 shall be applied in 
accordance with their terms. Without limiting the generality of the 
foregoing, if any portion of this Section 9 shall be invalidated on any 
ground, the Corporation shall nevertheless indemnify an Indemnitee to the 
full extent permitted by any applicable portion of this Section 9 that shall 
not have been invalidated and to the full extent permitted by law with 
respect to that portion that has been invalidated.

     9.4  SUCCESSORS AND ASSIGNS.  This Section 9 shall be binding upon the 
Corporation, its successors and assigns, and shall inure to the benefit of 
the Indemnitee's heirs, administrators, executors, personal representatives 
and assigns and to the benefit of the Corporation, its successors and assigns.

     9.5  AMENDMENTS.  No amendment to or modification of this Section 9 or 
any portion hereof shall limit any Indemnitee's entitlement to 
indemnification in accordance with the provisions

                                      16
<PAGE>

hereof with respect to any acts or omissions of Indemnitee which occur or 
accrue prior to such amendment or modification.

     9.6  CONTRIBUTION.  If the indemnity provided for in this Section 9 is 
for any reason unavailable or insufficient to hold harmless an Indemnitee 
with respect to any Expenses, the Corporation shall make a contribution to 
the Indemnitee for such liabilities to which the Indemnitee may be subject in 
such proportion as is appropriate to reflect the intent of this Section 9.

     9.7  RELIANCE.  Each person who is serving as an Indemnitee shall be 
deemed to be doing so in reliance upon the indemnification provided for in 
this Section 9.  The rights of an Indemnitee hereunder shall be contract 
rights and shall vest in the Indemnitee upon the occurrence of the event, or 
the first event in a chain of events, giving rise to such Claim; provided 
that the adoption of the By-laws shall not affect any right or obligation of 
the Corporation or of any Indemnitee which existed prior to such adoption.

     9.8  NONEXCLUSIVITY.  (a)  The rights conferred herein on any person 
shall (i) be severable, (ii) not be exclusive of any other rights which such 
person may have or hereafter acquire under any statute, certificate of 
incorporation, contract or other agreement, authorization of stockholders or 
disinterested directors or otherwise, and (iii) continue as to an Indemnitee 
who has ceased to serve on behalf of the Corporation in respect of all claims 
arising out of action (or inaction) occurring prior to such time.

          (b)  It is the intent of the Corporation to indemnify and hold 
harmless Indemnitee to the fullest extent permitted by Delaware Law, as such 
law exists or may be amended after the date the By-laws are adopted, but, in 
the case of any such amendment, only to the extent that such amendment 
permits the Company to provide broader indemnification rights than Delaware 
Law permitted prior to the amendment, notwithstanding any provision in 
Section 9 to the contrary.

     9.9  INSURANCE.  The Corporation may procure or maintain insurance or 
other similar arrangement on behalf of any Indemnitee or any person who is or 
was an employee or agent of the Corporation, or is serving at the request of 
the Corporation as an employee or agent of another corporation, partnership, 
joint venture, trust or other enterprise, against any liability asserted 
against or incurred by him in his capacity as such, or arising out of his 
status as such, whether or not the Corporation would have the power to 
indemnify him against such liability under the provisions of Delaware Law.  
Without limiting the power of the Corporation to procure or maintain any 
other kind of insurance or similar arrangement, the Corporation may create a 
trust fund or other form of self-insurance arrangement for the benefit of any 
Indemnitee or such other person to the fullest extent authorized by Delaware 
Law.

exercise any rights in respect to any change, conversion or exchange of stock 
or for the purpose of any other lawful action, the Board may fix in advance a

Except as otherwise provided in the By-laws, a determination of stockholders

stock, subject to the provisions of the Certificate of Incorporation.  Before 
payment of any dividend, there may be set aside out of any funds of the 
Corporation available for dividends such sum or sums as the directors from 
time to time, in their absolute discretion, think proper as a reserve or 
reserves to meet contingencies, or for equalizing dividends, or for repairing 
or maintaining any property of the Corporation, or for such other purpose as 
the directors shall think conducive to the interest of the Corporation, and 
the directors may modify or abolish any such reserve in the manner in which 
it was created.

     10.3 CHECKS.  All checks or demands for money and notes of the 
Corporation shall be signed by such officer or officers or such other person

of Directors.  The seal may be used by causing it or a facsimile thereof to 
be impressed or affixed or reproduced or otherwise.

Dear Sirs:

    We have acted as counsel to Freeport-McMoRan Sulphur Inc. (the "Company") 
in connection with the preparation of the registration statement on Form S-1 
(the "Registration Statement") filed by you with the Securities and Exchange 
Commission on the date hereof, with respect to the distribution of up to 
5,338,513 shares of Common Stock, $.01 par value per share together with 
associated preferred stock purchase rights (the "Shares") in connection with 
the merger of Freeport-McMoRan Inc. with and into IMC Global Inc. pursuant to 
the terms of a Merger Agreement dated August 26, 1997 (the "Merger 
Agreement").  In so acting, we have examined original, or photostatic or 
certified copies, of such records of the Company, certificates of officers of 
the Company and of public officials, and such other documents as we have 
deemed relevant.  In such examination, we have assumed the genuineness of all 
signatures, the authenticity of all documents submitted to us as originals, 
the conformity to original documents of all documents submitted to us as 
certified or photostatic copies and the authenticity of the originals of such 
documents.

    Based upon the foregoing, we are of the opinion that the Shares, when
issued in accordance with the terms of the Merger Agreement, shall be duly
authorized, validly issued, fully paid and non-assessable shares of the
Company's Common Stock.

    We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and the reference to us under the caption "Legal Matters"
as counsel for the Company.  In giving this consent, we do not admit that we are
within the category of persons whose consent is required under Section 7 of the
Securities Act of 1933, as amended, or the general rules and regulations of the
Commission.

                             Very truly yours,

Prospectus of IMC Global Inc. and Freeport-McMoRan Inc. (the "Prospectus") 
and the Freeport-McMoRan Sulphur Inc. Registration Statement on Form S-1, 
dated November 12, 1997, relating to the merger of Freeport-McMoRan Inc. into 
IMC Global Inc. (the "Merger"), and the distribution of Freeport-McMoRan 
Sulphur Inc. common stock in the Merger, respectively.

     This will confirm that our opinions are set forth under the headings

"Certain Federal Income Tax Consequences" in the Form S-1, and such 
discussions are fair, complete, and accurate in all material respects.  Our

     We consent to the use of this opinion as an exhibit to the Form S-4
Registration Statement and the Form S-1 Registration Statement filed with the
SEC in connection with the Merger and the distribution of Freeport-McMoRan
Sulphur Inc. common stock, and to the references to us as tax counsel to FTX in
such filings.

                                             Very truly yours,

ability of Company to terminate the employment of any Transferred Employee or to

    3.   PENSION PLANS.

         (a)  As of the Effective Time, FTX shall cause to be transferred to a
newly-created separate defined-benefit pension plan (the "Spin-Off Plan") the
assets and liabilities of the FTX Pension Plan that are attributable to the
Transferred Employees.  The Spin-Off Plan shall have substantially the same
terms and conditions as the FTX Pension Plan, subject to any limitation required
by Company regarding accrual of benefits after the Effective Time.  In
connection with the transfer, FTX shall make all filings and submissions to
governmental agencies as are required by law, and shall make all amendments to
the FTX Pension Plan and related trust agreement as are necessary.  The accrued
benefits attributable to the Transferred Employees shall be 100% vested.  The
transfer shall be made as of the "Transfer Date", which shall be the Effective
Time, or at such other time as is mutually agreed upon by FTX and Company.

         (b)  The amount of the assets required under Paragraph (a) to be
transferred (the "Transfer Amount") shall be equal to the Account Balances of
the Transferred Employees under the FTX Plan as of the Effective Time, including
Annual Additions with respect to Earnings throught the Effective Time and Annual
Interest Credits through the Effective Time.  The Transfer Amount shall in no
event be less than the minimum amount necessary to satisfy all requirements of
the Code  and regulations.  The Transfer Amount shall be transferred within 30
days after the Effective Time.  The terms Account Balance, Earnings, Annual
Additions, and Annual Interest Credits as used in this paragraph have the same
meaning as in the FTX Pension Plan.

         (c)  As of the Effective Time (or such other date as agreed to by the
Company and FTX) Company shall become the sponsor of the Spin-Off Plan referred
to in Paragraph (a) (hereafter "Company Pension Plan") and its related trust,
which will hold the Transfer Amount.  Company shall take all necessary steps,
including the prompt filing of an application to the Internal Revenue Service
for a favorable determination letter, to assure that the Company Pension Plan is
qualified under Internal Revenue Code Section 401(a).  As of the date of the

                                      4
<PAGE>


transfer of the Transfer Amount, the Company Pension Plan shall assume the
liabilities of the FTX Pension Plan that are attributable to the Transferred
Employees, and the FTX Pension Plan (and FTX as sponsor of the FTX Pension Plan)
shall have no further liability with respect to the Transferred Employees. 
Company shall be under no obligation to accrue benefits under the Company
Pension Plan after the Effective Time at the same rate as under the FTX Pension
Plan, and may terminate the Company Pension Plan.  Company shall have no
obligations or liabilities arising under or attributable to the FTX Pension
Plan, other than as described above.

         (d)  As of the Effective Time, Company shall assume the liabilities in
respect of Transferred Employees under the FTX EBP and the FTX Grandfathered
Plan, and FTX shall have no further obligation under such plans with respect to
such employees.  As consideration  for the assumption of such liabilities by
Company, FTX shall pay to Company an amount, estimated at $700,000, that the
plans' actuary shall determine is equal to the value as of the Effective Time of
the benefits accrued under the plans by the Transferred Employees.  The value of
a Transferred Employee's accrued benefit under the FTX EBP shall be equal to the
difference between the Participant's actual Account Balance under the FTX
Pension Plan and the Account Balance the Participant would have had under the
assumptions set forth in the FTX EBP.  The value of a Transferred Employee's
accrued benefit under the FTX Grandfathered Plan shall be determined under the
assumptions of that plan as if the Transferred Employee had retired as of the
Effective Time and elected to receive an immediate lump-sum benefit.  The
payment with respect to the FTX Grandfathered Plan shall be made only with
respect to the Transferred Employees (if any) who have reached the age of 55 by
the Effective Time. Company shall have no obligation to allow Transferred
Employees to continue to accrue benefits under such plans after the Effective
Time.

    4.    INDIVIDUAL ACCOUNT PLANS

         (a)  As of the Effective Time, Company shall adopt the FTX ECAP and
its related trust, and the documents governing said plan and trust shall be
amended by FTX and the Company to provide that, commencing at the Effective
Time, FTX will no longer have any powers or duties with respect to said plan and
trust, and the Company will have all powers and duties with respect to the plan
and trust that pertain to a plan sponsor. Within 15 days following the Effective
Time, FTX shall pay to the trustee of said trust any amounts payable to the
trust that it has received or withheld from participants, and any matching
contributions due under said plan.

         (b)  The FTX ECAP will be amended prior to the Effective Time to
permit it to hold Company shares.

         (c)  As of the Effective Time, the FTX SECAP document shall be amended
by FTX and the Company to provide that the Company assumes all liabilities in
respect of Transferred Employees under the FTX SECAP, and that FTX has no
further obligation under the FTX SECAP with respect to the account balances of
Transferred Employees.  As consideration for the assumption of such liabilities
by Company, FTX shall pay to Company an amount equal to the account balances of
the Transferred Employees valued as of the date of the 

                                      5
<PAGE>

transfer.  As the vehicle for satisfying the liabilities assumed under this 
Paragraph (c), Company shall establish a Company SECAP.  All account balances 
of Transferred Employees in the Company SECAP shall be 100% vested.  Company 
shall have the right to amend or terminate the Company SECAP at any time, 
provided that no amendment shall reduce participant account balances.

         (d)  The FTX SECAP will be amended prior to the Effective Time to
require immediate payout with respect to all participants other than the
Transferred Employees.

    5.    STOCK PLAN ADJUSTMENTS; ESTABLISHMENT OF NEW ADJUSTED STOCK AWARD
PLAN.

         (a)  Effective as of the Distribution Date, the Company shall adopt
the Adjusted Stock Award Plan and shall take all action necessary in regard to
such Plan, the benefits provided thereunder, and the transactions contemplated
thereby to ensure compliance with Rule 16b-3, Section 162(m) and the Securities
Act, as applicable and as deemed desirable by the Company.  The Adjusted Stock
Award Plan shall be established for the exclusive purpose of granting the
Adjusted Company Awards as described in this Paragraph 5.

         (b)  Each outstanding FTX Award on the Distribution Date shall be
converted, in accordance with the procedures described in this Paragraph 5, into
an Adjusted FTX Award and an Adjusted Company Award.  The number of Company
Shares subject to an Adjusted Company Award shall be that number of Company
Shares that a record holder of the number of FTX Shares underlying the related
FTX Award would have received in the FTX Distribution.  Notwithstanding the
foregoing, if the FTX Award from which the Adjusted Company Award is derived
contains a right to receive a cash payment upon exercise of such FTX Award
related to and intended to defray the income tax liability associated therewith,
the number of Company Shares to be subject to the Adjusted Company Award,
determined according to the provisions of this Paragraph 5(b) (without
disregarding fractional Company Shares), shall be multiplied by 1.6556 and any
fractional Company Share resulting from such adjustment shall be disregarded. 
Such adjustment shall not affect the calculation of the per Company Share
exercise price of the Adjusted Company Award as set forth in Paragraph 5(e)
below.

         (c)  Each Adjusted Company Award and each Adjusted FTX Award will have
the same remaining duration as the FTX Award from which it was derived.  

         (d)  The exercise price of an Adjusted FTX Award shall be determined
by multiplying the exercise price of the FTX Award from which such Adjusted FTX
Award was derived by a fraction, the numerator of which is the FTX Net
Distribution Value, as defined below, and the denominator of which is the FTX
Distribution Value, as defined below.

         (e)  The exercise price of an Adjusted Company Award shall be
determined by multiplying the exercise price of the FTX Award from which such
Adjusted Company Award was derived by a fraction, the numerator of which is the
Company Distribution Value, as defined below, and the denominator of which is
the FTX Distribution Value.

         (f)  For purposes of the foregoing, the "Company Distribution Value"
shall be the weighted average per share price of the Company Shares on the New
York Stock Exchange on the first day that Company Shares are traded on the New
York Stock Exchange after the effective date of the merger of Freeport-McMoRan
Inc. into IMC Global Inc.; the "FTX Distribution Value" shall be the weighted
average per share price of the FTX Shares on the New York Stock Exchange on the
last day that FTX Shares are traded on the New York Stock Exchange before the
effective date of the merger of Freeport-McMoRan Inc. into IMC Global Inc. and
the "FTX Net Distribution Value" shall be (i) the FTX Distribution Value minus
(ii) the product of the Distribution Ratio, as hereinafter defined, and the
Company  Distribution Value.  The "Distribution Ratio" shall mean the number of
Company Shares distributed in the FTX Distribution per FTX Share, rounded to the
nearest one-millionth (.000001) of a Company Share.

    6.   DEFERRED COMPENSATION LIABILITIES.  As of the Distribution, FTX shall
calculate the liability of FTX and its subsidiaries in respect of the
Transferred Employees' deferred compensation, including without limitation
deferred awards under the FTX PIAP, FTX AIP, FTX LTPIP, and predecessor plans,
if any.  In consideration of a cash payment made promptly after the Distribution
Date by FTX to the Company in an amount equal to such accrued liability, the
Company will assume such liability in respect of Transferred Employees.

    7.   WELFARE PLANS.  

         (a)  As of the Effective Time, Transferred Employees shall cease
participation in all FTX Employee Plans and FTX Benefit Arrangements.  Except as
otherwise set forth in this Agreement or in the Merger Agreement, FTX shall
retain all obligations and liabilities under the FTX Employee Plans and FTX
Benefit Arrangements.

         (b)  FTX and its FTX Employee Plans and FTX Benefit Arrangements shall
retain responsibility for the administration, liability, cost of coverage and
all amounts payable by reason of claims incurred by Transferred Employees (and
their dependents and beneficiaries) on or before the Effective Time, by reason
of claims incurred by Retired Employees, and by reason of claims incurred by FTX
employees who as of the Effective Time were on a leave of absence or were
receiving long term disability benefits, sick leave benefits, or similar
benefits.  However, the Company shall assume responsibility for the
administration, liability, cost of coverage, and all amounts payable by reason
of employee benefit plan claims incurred by FTX employees (and their dependents)
who at the time the employees ceased active work for FTX performed services
primarily for the Transferred Businesses and who as of the Effective Time were
on a leave of absence or were receiving long term disability benefits, sick
leave benefits, or similar benefits.  For such purpose, unless otherwise agreed
by FTX and the Company, a claim is deemed incurred on the date of the occurrence
of (i) death, dismemberment, accident, or other loss in the case of claims under
life insurance and accidental death and dismemberment benefits, (ii) in the case
of a hospital stay, based on the date any such hospitalization is initiated, or
(iii) the date on which the treatment or other service was rendered or the
medicine, equipment, supply or other material was furnished, as the case may be,
which resulted in the charge or expense giving rise to the claim in the case of
all other claims.  This paragraph 7(b) shall not apply to claims under
applicable workman's compensation laws, the Jones Act, 46 U.S.C. Section 688,

                                      7
<PAGE>


the Longshore and Harbor Workers' Compensation Act, 33 U.S.C. Section 901, et.
seq., or under similar laws, or arising in connection with any occupational
injury or disease.

         (c)  As of the Effective Time, Company shall be responsible for
post-retirement benefit liabilities in respect of Transferred Employees and FTX
shall have no further obligation for such liabilities with respect to such
employees.  FTX shall pay to Company an amount that equals the liability that
has been accrued for such employees in accordance with the Financial Accounting
Standard Board No. 106 as provided in the Freeport-McMoRan Inc. Retiree Benefit
Plan's January 1, 1997 valuation report.

         (d)  The Company shall reimburse FTX for any payment (a "Reimbursable
Payment") that FTX properly makes to or on behalf of a Former Sulphur Employee
with respect to claims made after the Effective Time (or to an insurance company
to provide coverage for a Former Sulphur Employee after the Effective Time)
under the terms of any retiree medical, dental or life insurance plan or
arrangement of FTX.  No later than 30 days following the end of each calendar
quarter, FTX shall provide the Company with a report providing in reasonable
detail its calculation of the total amount of Reimbursable Payments made by FTX
during the quarter, less any refunds or other offsetting payments or credits
received by FTX.  The amount that Company shall reimburse FTX shall be equal to
the net amount of Reimbursable Payments by FTX, less the Credit Amount.  The
Credit Amount for each calendar quarter shall be equal to 25% of 9.5% of a
fraction of the "Surplus", as defined below, which fraction shall be derived by
dividing the liabilities under the FTX Pension Plan as of the Effective Time 
attributable to the Former Sulphur Employees by the total liabilities of the FTX
Pension Plan as of the Effective Time.  The Surplus shall be the fair market
value of the assets of the FTX Pension Plan, less the total liabilities of the
FTX Pension Plan, as of the Effective Time.  The assets and liabilities used in
this Paragraph 7(d) to calculate the Surplus and the appropriate fraction of the
Surplus shall be determined as of the Effective Time, but only with regard to
the portion of the FTX Pension Plan that remains after the transfer described in
Section 3(b) of this Agreement.  Furthermore, for purposes of this Section 7(d),
the assets and liabilities of the FTX Pension Plan (after the transfer described
in Section 3(b) shall be determined on a FAS 87/88 basis.  If the Credit Amount
for the current calendar quarter (plus any carried-forward excess from the
preceding calendar quarter) exceeds the Reimbursable Payments in a quarter no
payment shall be made between the parties.  Any excess Credit Amount for the
current calendar quarter shall be carried forward to the next calendar quarter. 
Company shall have the right to request an annual audit of the Reimbursable
Payments by an independent certified public accountant.  This paragraph is not
intended to limit any rights that FTX may have to reduce its obligations under
any such plans or arrangements.  However, FTX shall have no right to increase
its cost of benefits for any Former Sulphur Employee without obtaining 30-days
advance approval from Company.  Nor shall FTX have the right to reduce the cost
of coverage for any Retired Employees who are not Former Sulphur Employees
without likewise reducing the cost of coverage for the Former Sulphur Employees.

         (e)  With respect to employees and their dependents (other than
Transferred Employees) who experience a qualifying event as defined in 29 U.S.C.
Section 603 as a result of the transactions contemplated in the Contribution and
Distribution Agreement and the Merger 

                                      8
<PAGE>


Agreement and who elect COBRA continuation group health coverage under 29 
U.S.C. Sections 601, et. seq. ("COBRA Coverage"), the Company shall reimburse 
FTX for any Reimbursable Payment that FTX properly makes to or on behalf of 
such employees or dependents with respect to claims made after the Effective 
Time under the plan providing such COBRA coverage (or to an insurance company 
to provide COBRA Coverage for such employees or dependents after the 
Effective Time) in accordance with the procedures set forth in 7(d) above.

         (f)  The employee benefit plans established by the Company for the
benefit of Transferred Employees shall give effect, in determining or applying
any copayments, benefit limits, deductibles and maximum out-of-pocket
limitations to claims incurred, amounts paid by, and amounts reimbursed to, such
employees under the corresponding FTX Employee Plans or FTX Benefit Arrangements
maintained by FTX for their benefit immediately prior to the Effective Time. 
Further, the employee benefit plans established by the Company for the
Transferred Employees shall give credit for service at FTX and its subsidiaries
for purposes of any eligibility waiting periods and pre-existing condition
limitations.  The employee benefit plans established by the Company that provide
a maximum annual benefit, such as a vacation plan or wage and salary
continuation, will take into account benefits used by the Transferred Employees
under the corresponding FTX Employee Plans or FTX Benefit Arrangements
maintained by FTX for their benefit immediately prior to the Effective Time.

         (g)  The Company will give Transferred Employees full credit for
purposes of eligibility, vesting, benefit accrual and benefit entitlement (as
such purposes may be applicable) under the employee benefit plans of the Company
for such employees' respective service recognized or applied for such purposes
under the corresponding FTX Employee Plan or FTX Benefit Arrangement, to the
extent applicable.

         (h)  FTX and the Company shall provide each other with copies of such
records as are reasonably required to enable the parties to perform their
obligations hereunder.

    8.   CASH BONUSES.  As of the Effective Time, FTX shall in good faith
determine the total amount of cash incentive payments that it would have made to
the Transferred Employees under the FTX PIAP and the FTX PAP for 1997 (without
proration for a partial year), which determination shall be subject to the
limitations and other terms and conditions of Schedule  5.8(c) to the Merger
Agreement.  In consideration of a cash payment made promptly after the Effective
Time by FTX to the Company in an amount equal thereto, the Company will assume
the payment of such amounts to the Transferred Employees, which will be made as
soon as feasible after 1997 in accordance with any procedures it may establish
with respect to the payment of any cash incentive payments to Company employees.

    9.    EXPENSES.  Each of the Company and FTX shall pay its own expenses in
connection with the performance of its obligations under this Agreement.

    10.  GOVERNING LAW.  This Agreement shall be governed by and construed in
accordance with the internal laws of the State of Louisiana.

    11.  AMENDMENT AND WAIVER.  This Agreement may not be altered or amended,
nor may rights hereunder be waived, except by an instrument in writing executed
by each party, or in the case of a waiver by an instrument in writing executed
by the party against whom such waiver is to be effective.  No waiver of any
term, provision or condition of or failure to exercise or delay in exercising
any rights or remedies under this Agreement, in any one or more instances, shall
be deemed to be, or construed as, a further or continuing waiver of any such
term, provision, condition, right or remedy or as a waiver of any other term,
provision or condition of this Agreement.

    12.  COUNTERPARTS.  This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original instrument but all of
which together shall constitute but one and the same Agreement.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be executed as of the date first above written.

                                 MAIN PASS BLOCK 299

    THIS AGREEMENT, dated May 2, 1990, between:

    CHEVRON U.S.A. INC., a Pennsylvania corporation with its principal place of
    business in Louisiana at 935 Gravier Street, New Orleans, Louisiana 70112
    ("Seller); and

    FREEPORT-McMoRan RESOURCE PARTNERS, LIMITED PARTNERSHIP, a Delaware limited
    partnership ("Freeport"), with its principal place of business in Louisiana 
    at 1615 Poydras Street, New Orleans, Louisiana 70112, referred to herein as
    "Buyer",

                                 W I T N E S S E T H:

    That Seller desires to sell to Buyer and Buyer desires to purchase from 
Seller on the terms set forth in this Agreement those certain oil and gas 
interests and associated assets identified in Exhibits "A" and "B" attached 
hereto and made a part hereof.  Accordingly, Seller and Buyer agree as 
follows:

1.  SALE AND PURCHASE OF ASSETS

    1.1  ASSETS TO BE SOLD.  Seller shall sell, transfer, and assign, or cause
         others to sell, transfer and assign to Buyer, and Buyer shall purchase
         and receive the following, to-wit:

         1.1.1     All of Seller's right, title and interests in and to the
                   Segregated Lease, as defined in Exhibit "A".  Seller reserves
                   all other rights in the "Lease" (as identified in 
                   Exhibit "A"), such other rights being the "Retained Lease".

         1.1.2     All of Seller's right, title and interest in and to the
                   materials, equipment, services and contract rights described
                   in Exhibit "B" ("Physical Assets").

         The Segregated Lease and Physical Assets are hereinafter collectively
         referred to as "the Assets".  Such transfer of interests will be made 
         and be effective at Closing.

    1.2  INSTRUMENTS.  Except as may be otherwise noted in this Agreement, the
         Assets to be conveyed by Seller to Buyer Pursuant to Section 1.1 
         shall be conveyed by instruments in form and substance similar to 
         Exhibits "F-1" and "F-2," provided that the Physical Assets shall 
         be conveyed on an "as is" basis.  Seller shall execute such other 
         Bills of Sale as may be required by Buyer for the Physical Assets. 
         The interests to be conveyed by Buyer to Seller shall be conveyed 
         by an instrument in form and substance similar to Exhibit "F-3" or 
         "F-4", as applicable.

    1.3  SELLER'S ELECTION TO EFFECT IRC Section 1031 EXCHANGE.  In the event 
         Seller so elects, Buyer agrees to attempt in good faith to 
         accommodate Seller in effecting a tax-deferred exchange of the 
         properties identified in Section 1.1.1, at the value referred to in 
         Section 2.1.1, under Internal Revenue Code Section 1031, as 
         amended. Seller shall have the right to elect this tax-deferred 
         exchange at any time prior to the date of Closing. If Seller elects 
         to effect a tax-deferred exchange, Buyer agrees to execute 
         additional escrow instructions, documents, agreements, or 
         instruments to effect the exchange, provided that Buyer shall incur 
         no additional costs, expenses, fees, taxes (including any state or 
         local sales, use or transfer taxes) or liabilities as a result of 
         or connected with the exchange. Further, in the event Seller elects 
         to effect a tax-deferred exchange, such transaction shall be 
         subject to the terms and provisions of Section 7.3 hereof and of an 
         agreement similar in form and substance to that attached hereto as 
         Exhibit "F-5."

<PAGE>


         In connection with any such exchange, Buyer does not warrant or 
         represent that any such property selected by Seller will be 
         suitable for Sellers purpose nor that such exchange will qualify 
         for tax deferred treatment under Internal Revenue Code Section 
         1031. Seller will indemnify Buyer for any costs, expenses, fees, 
         taxes or liabilities arising from or in connection with any such 
         exchange, and for any claims made by any third party relating to 
         such exchange.

2.  TERMS OF SALE

    2.1  PRICE.  As consideration for the sale of the Assets, Buyer shall pay 
         to Seller or its designee the following amounts:

         2.1.1     For the Segregated Lease, One Hundred Thirty-Seven Million 
                   United States dollars ($137,000,000).
                   
         2.1.2     For the Physical Assets, the amounts set forth in said 
                   Exhibit "B" (as adjusted for the costs and expenses incurred
                   up to the Closing).

         The amounts set forth in Sections 2.1.1 shall be paid at Closing by 
         wire transfer in Federal Funds to a bank account to be designated 
         by Seller. An invoice with supplier's documentation for the items 
         identified in Section 2.1.2 will be forwarded to Freeport under 
         separate cover within thirty (30) days after Closing. This invoice 
         will contain payment instructions and information as to the status 
         and condition of the materials and equipment being transferred.
         
    2.2  ASSUMPTION OF OBLIGATIONS AND LIABILITIES.  As additional 
         consideration for the sale of the Assets, Buyer shall assume all 
         obligations and liabilities relating to the ownership or use of the 
         Assets, including but by no means limited to the payment of 
         Production Payments, overriding royalty payments or the Final 
         Payment (if applicable) owing to Seller hereunder, and reclamation 
         and the plugging and abandonment of all wells drilled on the 
         Segregated Lease (but not including wells heretofore drilled 
         through the Segregated Lease to depths deeper than a subsea depth 
         of 1,900 feet), whether now or hereafter located on the Segregated 
         Lease.  Buyer shall also assume all accounting and reporting duties 
         and obligations associated with use and ownership of the Assets 
         subsequent to the Closing. Such reclamation and plugging and 
         abandonment shall be performed in a good and workmanlike manner and 
         in accordance with the rules and regulations of the Minerals 
         Management Service and all other applicable laws.  The sale will be 
         made subject to, and Buyer assumes all rights and obligations 
         arising under and in accordance with, the terms of the Segregated 
         Lease, and the agreements listed on Exhibit "A" hereto which affect 
         the Segregated Lease.  Buyer shall assume and be responsible for 
         all obligations of Seller accruing under such agreements after the 
         Closing, to the extent such agreements apply to the Segregated 
         Lease.

    2.3  INDEMNIFICATION BY BUYER.  Buyer shall defend and indemnify Seller, and
         shall save and hold Seller (and Sellers assignee under an exchange
         agreement) free and harmless, from and against any and all liabilities,
         penalties, fines, losses, injuries including death, demands, damages,
         claims and causes of action, of any nature whatsoever, arising directly
         or indirectly from or in connection with:

         2.3.1     Seller's #11 well, previously drilled within the Segregated 
                   Lease and which Seller represents was properly plugged and 
                   abandoned by Seller;

         2.3.2     Buyer's ownership or use of the Segregated Lease, or 
                   operations conducted or caused to be conducted by or on 
                   behalf of Buyer on, in, under or adjacent to the Segregated 
                   Lease for the exploration for or development and production, 
                   gathering, transportation, processing or treatment of oil or 
                   gas or sulphur or any other mineral or substance from or 
                   allocable to the Segregated Lease,

                                      2
<PAGE>


              except to the extent that such liabilities, losses, injuries 
              including death, demands, damages, claims and causes of action are
              finally established, in a ruling from a court of competent 
              jurisdiction not subject to appeal, to be the result of Seller's 
              (or, pursuant to an exchange agreement, Seller's assignee's) 
              negligence or other legal fault.

    2.4  INDEMNIFICATION BY SELLER.  Seller shall save and hold Buyer free and
         harmless from and against any and all liabilities, penalties, 
         fines, losses, injuries including death, demands, damages, claims 
         and causes of action, of any nature whatsoever, arising directly or 
         indirectly from or in connection with Seller's ownership or use of 
         the Retained Lease, or operations conducted or caused to be 
         conducted by or on behalf of Seller on, in, or under the Retained 
         Lease for the exploration for or development and production, 
         gathering, transportation, processing or treatment of oil or gas or 
         sulphur or any other mineral or substance from or allocable to the 
         Retained Lease, except to the extent that such liabilities, losses, 
         injuries including death, demands, damages, claims and causes of 
         action are finally established, in a ruling from a court of 
         competent jurisdiction not subject to appeal, to be the result of 
         Buyer's negligence or other legal fault.

    2.5  CLOSING. The Closing of the transactions contemplated herein and the
         transfer of the Assets shall occur on or before June 1, 1990 (unless
         additional time is required to satisfy the conditions precedent to 
         Closing, as provided in Section 7 hereof), at Chevron's office at 935 
         Gravier Street, New Orleans, Louisiana, at 10:00 a.m., local time, or 
         such other date, time, and place as Seller and Buyer may agree in

3.  INTERESTS TO BE GRANTED TO BUYER BY SELLER

    3.1  PRODUCTION PAYMENT.

         3.1.1     Buyer shall grant, transfer, assign and convey to Seller a
                   "Production Payment" with regard to Buyer's oil production 
                   from or attributable to the Segregated Lease (or any 
                   extension, renewal or replacement of the Segregated Lease 
                   acquired hereafter by Buyer or a parent, subsidiary or 
                   affiliate of Buyer). Said Production Payment shall be 
                   conveyed by an instrument in form and substance similar 
                   either to Exhibit "F-3" or Exhibit "F-4" hereto, as 
                   applicable pursuant to Section 3.2 or 3.3, and is to be 
                   calculated on a calendar year basis, in accordance with
                   Exhibits "C" and "D" attached hereto. Buyer shall pay such
                   Production Payment to Seller on or before a date thirty (30)
                   days after the end of the calendar year to which such payment
                   applies, or on or before a date sixty (60) days after the 
                   discontinuation of Production Payments as provided in 
                   Section 3.2 hereof.

         3.1.2     Concurrently with any such payment made pursuant to Section
                   3.1.1, Buyer shall furnish Seller a statement which shall 
                   include information and data supporting and verifying the 
                   amount of the Production Payment being tendered. Said 
                   payment and said statement shall be sent to the following 
                   address:

         3.1.3     If Buyer does not make such a payment as required by Section

    3.2  OVERRIDING ROYALTY INTEREST - NO EXCHANGE.

         3.2.1     This Section 3.2 shall apply only in the event Seller elects
                   not to effect a tax-deferred exchange as provided in 
                   Section 1.3.

         3.2.2     After cumulative oil production from or allocable to the
                   Segregated Lease produced, saved or used equals or exceeds 
                   36 million stock tank barrels of oil, measured at Buyer's 
                   production facility platform located on or adjacent to the 
                   Segregated Lease (the ability to produce and save such 
                   volumes of oil not being guaranteed by Buyer), or after a 
                   date twenty (20) years from the date of first such oil 
                   production, whichever occurs first, Seller's Production 
                   Payment as provided for in Section 3.1.1 above shall convert 
                   to an overriding royalty of 25% of the value of oil and gas 
                   production thereafter produced and saved or used from or 
                   allocable to the Segregated Lease. Such conversion shall be 
                   set forth in an instrument similar in form and substance to
                   that attached hereto as Exhibit "F-3." Notwithstanding 
                   anything foregoing in this Section 3.2 to the contrary, said 
                   overriding royalty shall be calculated, determined and paid 
                   on the same volumes of production on which the lessors 
                   royalty is calculated, determined and paid; provided, this 
                   25% overriding royalty due in any one month shall never 
                   exceed 50% of the "net operating revenue" for such month. For
                   purposes of this Section 3.2, "net operating revenue" is 
                   defined as gross value realized by the Buyer on production 
                   saved and sold or used in the calendar month, less the 
                   lessor's royalty and normal operating expenses as outlined in
                   Exhibit "E" attached hereto (excluding major workover
                   expenses (i.e., well work requiring a drilling or workover 
                   rig), plugging and abandoning costs, and other expenditures 
                   of a capital nature). Said overriding royalty shall be 
                   calculated on the same basis as the lessors royalties as 
                   provided for in the Segregated Lease and, based on such 
                   calculation, shall be paid concurrently with payment of 
                   royalties under the lease covering the Segregated Lease.  
                   Additionally, said overriding royalty shall bear its 
                   proportionate share of present or future severance, windfall 
                   profits, excise or similar taxes. Any adjustments to the 
                   overriding royalties so paid required by the 50% of net 
                   operating revenue limitation set forth above shall be based 
                   on accrued expenses in accordance with generally accepted
                   accounting principles adjusted to actual expenses in 
                   succeeding months and as consistently applied. Resulting 
                   adjustments to the 25% overriding royalty interest payment 
                   shall be made during such succeeding month or by direct 
                   payment (after confirmation of the appropriate adjustments) 
                   to the party due such payment.


    3.3  OVERRIDING ROYALTY INTEREST AND FINAL PAYMENT - EXCHANGE.

         3.3.1     This Section 3.3 shall apply only if Seller elects to effect 
                   a tax-deferred exchange as provided in Section ?.

         3.3.2     After a date twenty (20) years from the date of first oil
                   production from or allocable to the Segregated Lease, 
                   Seller's Production Payment as provided for in Section ? 
                   above shall convert to an overriding royalty of 25% of the 
                   value of oil and gas production thereafter produced and saved
                   or used from or allocable to the Segregated Lease. Such 
                   conversion shall be set forth in an instrument similar in 
                   form and substance to that attached hereto as Exhibit "F-4." 
                   Notwithstanding anything foregoing in this Section 3.3 to the
                   contrary, said overriding royalty shall be calculated, 
                   determined and paid on the same volumes of production on 
                   which the lessor's royalty is calculated, determined and 
                   paid; provided, this 25% overriding royalty due in any one 
                   month shall never exceed 50% of the "net operating revenue" 
                   for such month. For purposes of this Section ?, "net 
                   operating revenue" is defined as gross value realized by
                   the Buyer on production saved and sold or used in the 
                   calendar month, less the lessor's royalty and normal 
                   operating expenses as outlined in Exhibit 'E' attached 
                   hereto (excluding major workover expenses (i.e., well work 
                   requiring a drilling or workover rig), plugging and 
                   abandoning costs, and other expenditures of a capital 
                   nature).

<PAGE>


                   Said overriding royalty shall be calculated on the same basis
                   as the lessor's royalties as provided for in the
                   Segregated Lease and, based on such calculation, shall be 
                   paid concurrently with payment of royalties under the lease 
                   covering the Segregated Lease. Additionally, said overriding 
                   royalty shall bear its proportionate share of present or 
                   future severance, windfall profits, excise or similar taxes. 
                   Any adjustments to the overriding royalties so paid required 
                   by the 50% of net operating revenue limitation set forth 
                   above shall be based on accrued expenses in accordance with 
                   generally accepted accounting principles adjusted to actual 
                   expenses in succeeding months and as consistently applied. 
                   Resulting adjustments to the 25% overriding royalty interest 
                   payment shall be made during such succeeding month or by 
                   direct payment ( after confirmation of the appropriate 
                   adjustments) to the party due such payment.

         3.3.3     If, prior to a date twenty (20) years from the date of first 
                   oil production from or allocable to the Segregated Lease, oil
                   production from or allocable to the Segregated Lease equals 
                   or exceeds 36 million stock tank barrels, as measured at 
                   Buyer's production facility platform located on or adjacent 
                   to the Segregated Lease, then Section 3.3.2 shall be 
                   inapplicable, and Section 3.3.4 shall apply .

         3.3.4     After cumulative oil production from or allocable to the
                   Segregated Lease produced, saved or used equals or exceeds 
                   36 million stock tank barrels of oil, measured at Buyer's 
                   production facility platform located on or adjacent to the 
                   Segregated Lease (the ability to produce and save such 
                   volumes of oil not being guaranteed by Buyer, and the date 
                   of such point in time being referred to as the "Final Payment
                   Determination Date"), Seller's Production Payment or 
                   overriding royalty, as applicable, shall terminate, and in 
                   lieu thereof the "Final Payment," as defined hereafter, from 
                   Buyer to Seller shall be due. Within thirty (30) days after 
                   the Final Payment Determination Date, the parties hereto 
                   shall meet and agree on the total cumulative recoverable oil 
                   reserves ("Recoverable Reserves") which will be produced and
                   saved from or attributable to the Segregated Lease during its
                   economically productive life. If the parties cannot agree on 
                   the Recoverable Reserves within ten (10) days after their 
                   initial meeting on the matter, then DeGolyer and MacNaughton,
                   or another mutually acceptable consultant, shall conclusively
                   determine such Recoverable Reserves, with Seller and Buyer 
                   equally sharing the fees and expenses of such determination. 
                   Following determination of Recoverable Reserves, the parties 
                   shall determine Seller's "Final Payment" due from Buyer. The 
                   Final Payment shall be calculated as set forth in Exhibit 
                   "G," attached hereto and made a part hereof. Once the Final 
                   Payment has been made by Buyer to Seller, Seller shall have 
                   no further interest in the Segregated Lease or the production
                   therefrom.

    3.4  MANNER OF DEVELOPMENT AND PRODUCTION.  The parties recognize the 
         unique nature, risks and rewards of the simultaneous exploitation 
         of sulphur and oil and gas reserves from the same geologic trap. 
         Buyer shall have the exclusive right to determine the manner of 
         development and production of the Segregated Lease and Buyer's 
         sulphur lease.

4.  TAXES

    PAYMENT OF TAXES.  All ad valorem, property, and other similar forms of 
    taxes for 1990 allocable to the Assets, which have been paid by Seller 
    or which have accrued on or before the Closing, shall be prorated 
    between Seller and Buyer as of the Closing. Buyer shall be responsible 
    for all oil and gas production taxes, and any other similar taxes 
    applicable to oil and gas production occurring on and after the Closing, 
    except as otherwise provided for in this Agreement. Buyer shall be 
    responsible for all sales, use and similar taxes arising out of the sale 
    of the Assets. Buyer shall provide Seller with an offshore exemption 
    certificate or any other documentation if required under applicable law. 
    Buyer shall hold harmless and shall indemnify Seller for any sales or 
    use taxes

    assessed against Seller by any taxing authority in respect of this sale, 
    including the amounts of any penalties, interest and attorneys' fees.

    The parties expect that this purchase and sale will constitute an 
    isolated or occasional sale and will not be subject to sales or use tax 
    with any of the taxing authorities having jurisdiction over this 
    transaction, and as such, no sales tax will be collected by Seller from 
    Buyer at the date of Closing. Seller agrees to cooperate with Buyer in 
    demonstrating that the requirements for an isolated or occasional sale 
    or any other sales tax exemption have been met.

         5.2.5     Buyer shall be fully responsible for compliance with all
                   applicable laws, ordinances, rules and regulations and shall
                   promptly obtain and maintain all permits required by public
                   authorities in connection with the Assets purchased.

         5.2.6     Buyer has made or arranged for others to make an inspection 
                   of the Assets. Subject to Seller's foregoing representations
                   and warranties, Buyer accepts all Physical Assets in "as 
                   is and where is" condition, with an express acceptance and 
                   understanding of the representations and disclaimers 
                   contained herein.

         5.2.7     Buyer acknowledges that the Physical Assets have been used or
                   planned for use for oil and gas drilling and producing
                   operations, related oil field operations and possibly the 
                   storage

                   and disposal of waste materials incidental to or occurring 
                   in connection with such operations, and that Buyer has 
                   entered into this Agreement on the basis of Buyer's own 
                   investigation of the physical condition of the Physical 
                   Assets. Buyer hereby agrees to assume full responsibility 
                   for compliance with all obligations or regulations concerning
                   all of such conditions, known or unknown, and further agrees 
                   to indemnify Seller for same.


6.  ADDITIONAL COVENANTS

    6.1  APPROVALS AND CONSENTS.

         6.1.1     FORM OF TITLE OF ASSIGNED LEASEHOLD RIGHTS.  The transfer and
                   assignment of the Segregated Lease, in the manner intended by
                   Seller and Buyer hereunder, are subject to the approval by 
                   the Minerals Management Service ("MMS"), United States 
                   Department of the Interior. It is the intent and desire of 
                   the parties that the Segregated Lease will be effectively 
                   segregated by the MMS from the Retained Lease, it being 
                   contemplated by Seller and Buyer that the Segregated Lease 
                   and Retained Lease will become separate and distinct 
                   leases and that the anticipated segregation will be 
                   approved by the appropriate officer of the MMS 
                   simultaneously with, and effective as of the Closing. 
                   Seller and Buyer shall work together to obtain such 
                   approvals as appropriate, and will attempt to obtain 
                   concurrence in such segregation from the Secretary of the 
                   Interior ("Secretary"); provided, however, that such 
                   approval by the Secretary shall not be a condition 
                   precedent to Closing, but rather a condition subsequent to 
                   which Section 6.1.3 shall apply if such Secretary's 
                   approval is not granted. Seller shall execute and deliver 
                   to Buyer such instruments, subject to the provisions of 
                   this Agreement, as may be required by the MMS to induce 
                   the MMS to segregate the Segregated Lease. It is the 
                   intent of the parties hereto that Seller shall retain no 
                   obligation or responsibility to operate the Segregated 
                   Lease after same has been assigned to Buyer, that Seller 
                   shall execute any and all necessary Designations of 
                   Operator to a company designated by Buyer and acceptable 
                   to the parties; and that such Designations of Operator 
                   shall be approved by the appropriate officer of the MMS 
                   simultaneously with, and effective as of, the Closing.
                   
         6.1.2     DISAPPROVAL BY MMS.  If the MMS will not, or does not, 
                   approve the segregation of the Segregated Lease from the 
                   Retained Lean as contemplated in Section 6.1.1, after 
                   Seller's and Buyer's good faith attempts to obtain such 
                   approval, the parties shall meet and determine whether an 
                   alternative means can be found which would provide Buyer 
                   with the intended rights in the Segregated Lease, as 
                   defined herein, and be acceptable in form and effect to 
                   Seller, Buyer and the MMS under its delegated authority. 
                   If an alternative which is acceptable to Seller, Buyer and 
                   the MMS cannot be found to the contemplated transfer as 
                   set forth in Section 6.1.1, within six (6) months after 
                   the rejection by the MMS of the contemplated segregating 
                   assignment and transfer of the Segregated Lease, this 
                   Agreement will terminate without liability or obligation 
                   on the part of Seller or Buyer, except for (a) the 
                   obligation of Buyer to reassign the Segregated Lease to 
                   Seller, (b) the obligation of the Seller to return the 
                   purchase price to Buyer, and (c) other settlement of 
                   accounts provided for herein, or necessary and appropriate 
                   under the circumstances.

         6.1.3     DISAPPROVAL BY SECRETARY.  If the MMS approves the 
                   segregation of the Segregated Lease from the Retained 
                   Lease as contemplated in Section 6.1.1, and the Secretary 
                   does not approve such segregation, after Seller's and 
                   Buyer's good faith attempts to obtain such approval, then 
                   at Buyer's request the parties shall meet and determine 
                   (1) whether the transfer instruments theretofore executed, 
                   as interpreted by the Secretary, effect a form of transfer 
                   and assignment which is acceptable to the parties under 
                   the circumstances, or (2) whether additional documents or 
                   agreements need be executed to effect the intended 
                   transfer more perfectly, or (3) whether an alternative 
                   means can be found which would provide 


                                      8
<PAGE>



                   Buyer with the intended rights in the Segregated Lease, as 
                   defined herein, and be acceptable in form and effect to 
                   Seller, Buyer and the applicable governmental authority 
                   (i.e., the MMS or the Secretary). If an alternative which 
                   is acceptable to Seller, Buyer and the applicable 
                   governmental authority cannot be found to the contemplated 
                   transfer as set forth in Section 6.1.1, within six (6) 
                   months after the rejection by the Secretary of the 
                   contemplated segregating assignment and transfer of the 
                   Segregated Lease, this Agreement will terminate without 
                   liability or obligation on the part of Seller or Buyer, 
                   except for (a) the obligation of Buyer to reassign the 
                   Segregated Lease to Seller, (b) the obligation of the 
                   Seller to return the purchase price to Buyer, and (c) 
                   other settlement of accounts provided for herein, or 
                   necessary and appropriate under the circumstances.


    6.2  SERVICE CONTRACTS, PURCHASE ORDERS.  Certain of the service contracts 
         and purchase orders entered into by Seller, with respect to the 
         Physical Assets listed in Exhibit B, are not assignable by Seller; 
         consequently, Buyer and Seller shall work together in good faith to 
         the end that Buyer receive the benefit of such service contracts and 
         purchase orders, including all warranties, to the extent that such 
         affect the materials, equipment and services to be received by Buyer 
         pursuant hereto; provided, however, it is not the intent hereof that 
         Seller shall undertake any obligation or warranty in lieu of the 
         obligations of any vendor or contractor. Seller and Buyer shall 
         execute appropriate documentation required by either vendors, 
         contractors or Seller to effectuate a substitution of Buyer for 
         Seller under such service contracts and purchase orders.


    6.3  OPERATIONS PRIOR TO CLOSING.  After the date of this Agreement and 
         prior to the Closing, Seller shall use and maintain the Assets in 
         substantially the same manner in which they have been used and 
         maintained prior to this Agreement The parties have previously 
         agreed and by this Agreement confirm and establish that as of 
         February 19, 1990, all obligations, liabilities, duties, rights and 
         benefits associated with the physical Assets and their existing 
         purchase orders and service contracts as set forth in Exhibit "B" 
         shall be assumed by and same shall inure to the benefit of Buyer The 
         parties further agree that, if for any reason the Closing under this 
         Agreement is not consummated, they will use their good faith efforts 
         to release, exchange and balance the costs incurred by the parties 
         as a result of the allocation of costs before and after such date, 
         by payment to Buyer or Seller (as required), within sixty (60) days 
         following the termination of this Agreement, of an agreed-upon 
         amount of money, along with execution and delivery of such documents 
         as are required.


    6.4  SELLER'S OPERATIONS AFTER CLOSING.  From and after the Closing, Seller
         shall not conduct thereafter any oil and gas exploration and 
         development operations on Block 299, Main Pass Area, by drilling or 
         producing through the horizons and formations from the surface down 
         to a subsea depth of 1900 feet on the Segregated Lease. Accordingly, 
         unless otherwise consented to or waived by Buyer, which consent 
         shall not be unreasonably withheld, Seller shall conduct all oil and 
         gas exploration, development and production operations on the 
         Retained Lease below the subsea depth of 1900 feet under the 
         Segregated Lease by drilling directional wells from surface 
         locations totally outside the area covered by the Segregated Lease 
         to bottomhole locations below the subsea depth of 1900 feet under 
         the Segregated Lease. Such wells shall not at any point intersect 
         the Segregated Lease. If through inadvertence any portion of a well 
         drilled by Seller does penetrate the Segregated Lease at any depth, 
         then upon discovery of such penetration Seller shall advise Buyer in 
         writing, and unless waived by Buyer, Seller shall sidetrack such 
         well out of the Segregated Lease and into the Retained Lease. Waiver 
         by Buyer of such sidetracking shall not be construed a waiver of 
         Seller's indemnity hereunder, but an attempt by Buyer to mitigate 
         Seller's damages.


    6.5  ACCESS TO ASSETS.  At all times prior to the Closing, if this Agreement
         shall not have first been terminated, Buyer and the employees and 
         agents of Buyer shall have access to the Assets at Buyer's sole 
         cost, risk and expense, and during normal business hours. Seller 
         shall have the right to regulate reasonably the hours and frequency 
         of Buyer's access to the Assets, so as not to interfere unreasonably 
         with Seller's other business and so as to allow Seller to have a 
         representative present 


                                      9
<PAGE>


         (at Seller's option) during Buyer's access. Buyer shall give Seller 
         at least forty-eight (48) hours' notice, during normal business hours,
         of Buyer's desire to access the Assets.

    6.6  CASUALTY LOSS.  In the event any Physical Asset, including fixtures and
         improvements, to be sold hereunder is damaged by fire or other calamity
         before Closing, Seller may repair the damage at its cost or, at its 
         sole option, either reduce the purchase price by the cost of the 
         damage or withdraw the damaged Physical Asset from the sale and 
         reduce the purchase price by the undamaged value thereof.

7.  CONDITIONS PRECEDENT TO CLOSING

    7.1  SELLER'S CONDITIONS PRECEDENT.  The obligations of Seller to consummate
         the transactions contemplated by this Agreement are subject to each of 
         the following conditions:

                   authority shall have been instituted or threatened (and 
                   not subsequently dismissed, settled or otherwise 
                   terminated) which might restrain, prohibit or invalidate 
                   any of the transactions contemplated by this Agreement, 
                   other than an action or proceeding instituted or 
                   threatened by Seller or any of its affiliates.

         7.1.3     Seller shall have executed appropriate amendments to the 
                   existing federal unit agreement and unit operating 
                   agreement to delete and exclude the Segregated Lease from 
                   such unit agreement and unit operating agreement. It is 
                   anticipated that such amendments will be approved by the 
                   MMS simultaneously with, and effective as of the Closing. 
                   The parties intend and desire that the Segregated Lease 
                   will be owned by Buyer, subject to the terms and 
                   provisions of this Agreement, but not subject to the 
                   existing federal unit agreement or any existing operating 
                   agreement, and that Seller shall retain no obligation or 
                   responsibility to operate the Segregated Lease.

         7.1.4     Pursuant to application therefor by Buyer, and simultaneously
                   with segregation of the Segregated Lease from the Retained 
                   Lease, the MMS shall have approved a Suspension of 
                   Production or a Suspension of Operations, such that the 
                   Segregated Lease can be maintained in force and effect for 
                   a period of at least two (2) years, or until actual 
                   production of oil and/or gas can be established, whichever 
                   occurs first.

         7.1.5     All necessary parties shall have executed instruments, in 
                   forms substantially similar to those attached as Exhibits 
                   "F-1," "F-2," either "F-3" or "F-4," and "F-5," whereby 
                   Seller transfers its right, title and interest in the 
                   Assets to Buyer, and whereby Buyer assigns to Seller, the 
                   interests contemplated in Sections 3.1.1, 3.2 and/or 3.3. 
                   Further, if required by any vendor, contractor or either 
                   party hereto, all necessary parties shall execute separate 
                   Bills of Sale with respect to Physical Assets.

    7.2  BUYER'S CONDITIONS PRECEDENT.  The obligations of Buyer to consummate 
         the transactions contemplated by this Agreement are subject to each of 
         the following conditions:

         7.2.1     Seller shall have performed and complied with all terms of 
                   this Agreement required to be performed or complied with by 
                   Seller prior to Closing.

         7.2.2     Buyer and Chevron Pipe Line Company shall have reached a 
                   mutually satisfactory agreement with regard to transportation

                   Lease.

<PAGE>



         7.2.3     No action or proceeding by or before any governmental 
                   authority shall have been instituted or threatened (and not 
                   subsequently dismissed, settled, or otherwise terminated) 
                   which might restrain, prohibit or invalidate any of the 
                   transactions contemplated by this Agreement, other than an 
                   action or proceeding instituted or threatened by Buyer or any
                   of its affiliates.

         7.2.4     All necessary parties shall have executed instruments, in 
                   forms substantially similar to those attached as Exhibits 
                   "F-1," "F-2," either "F-3" or "F-4," and "F-5," whereby 
                   Seller transfers its right, title and interest in the 
                   Assets to Buyer, and whereby Buyer assigns to Seller, the 
                   interests contemplated in Sections 3.1.1, 3.2 and/or 3.3. 
                   Further, if required by any vendor, contractor or either 
                   party hereto, all necessary parties shall execute separate 
                   Bills of Sale with respect to Physical Assets.


    7.3  EFFECTS OF TAX-DEFERRED EXCHANGE.  If Seller elects to effect a
         tax-deferred exchange pursuant to Section 1.3, Buyer and Seller agree 
         to cooperate and execute additional assignments as prudently 
         required to effect the exchange, and in such event Seller shall 
         guarantee the performance of any intermediary corporation used as a 
         part of such exchange transaction. The parties contemplate execution 
         of a direct assignment from Seller to Buyer in the form attached 
         hereto as Exhibit "F-1", at the direction of the intermediary 
         corporation as set forth in Exhibit "F-5," which assignment shall be 
         filed for approval by the MMS and the Secretary of the Interior as 
         set forth in Section 6.1.1.


8.  MISCELLANEOUS

    8.1  PAYMENT OF EXPENSES AND FEES.  Buyer and Seller shall each bear its own
         costs and expenses, including but not limited to attorney's fees 
         incurred in connection with the transactions contemplated in this 
         Agreement; provided, however; Buyer shall pay all recording fees or 
         transfer taxes in connection with the recording of any instrument of 
         transfer of Assets from Seller to Buyer hereunder.

    8.2  NORM.  Any assignment of the Physical Assets shall contain the 
         following provision:

         8.2.1     It is expressly recognized and acknowledged that naturally
                   occurring radioactive material ("NORM") is normally 
                   associated with oil and gas producing operations, and as a 
                   result the Physical Assets transferred herein may be 
                   contaminated by NORM in that certain of the Physical 
                   Assets have previously been used in oil and gas producing 
                   operations. Accordingly, Buyer shall comply with 
                   applicable federal and applicable state laws and 
                   regulations governing NORM and governing Physical Assets 
                   contaminated by or containing NORM.

         8.2.2     The Physical Assets herein transferred which have previously 
                   been used in oil and gas producing operations shall be 
                   used only in connection with oil and gas producing 
                   activities, and shall not be subsequently transferred for 
                   unrestricted use unless the concentrations of NORM 
                   associated therewith are below the levels specified as 
                   allowable for unrestricted transfer as set forth in the 
                   Louisiana Radiation Regulations and subsequent amendments 
                   thereto, as adopted by the Louisiana Department of 
                   Environmental Quality.

         8.2.3     Buyer shall comply with all provisions of the Louisiana 
                   Radiation Regulations and all subsequent amendments 
                   thereto to the extent that the regulations are applicable 
                   to the Physical Assets herein transferred.
                   
         8.2.4     Buyer shall include the provisions of this Section 8.2 in any
                   subsequent sale or assignment of the Physical Assets herein
                   transferred which have previously been used in oil and gas
                   producing operations.


    8.3  TRANSPORTATION OF OIL.  Subject to partial reimbursement by Seller of
         certain costs as provided herein, and except as may be negotiated 
         between Buyer and the purchaser of the oil produced and saved from 


                                      11
<PAGE>



         the Segregated Lease, Buyer shall be responsible for all costs 
         associated with transporting oil from or attributable to the 
         Segregated Lease to the designated sales point.  If such oil is 
         transported through the common carrier pipeline system owned and 
         operated by Chevron Pipe Line Company ("CPL") from Main Pass 299B to 
         Main Pass 69 to the outermost flange of the Empire Terminal located 
         in Plaquemines Parish, Louisiana, then Buyer or the purchaser of 
         such oil will bear any and all costs and expenses associated with 
         the metering and transportation of production through such system to 
         the outermost flange of the Empire Terminal, including but not 
         limited to the following:

         8.3.1     Costs of pipeline installation, tie-in and maintenance 
                   associated with Buyer's connection of its production to 
                   Chevron Pipe Line Company's facilities on Seller's Main 
                   Pass 299B platform, it being understood and agreed that 
                   any plans or drawings for such installation or tie-in, and 
                   the actual work ultimately performed, shall be subject to 
                   Seller's prior review and approval, and subject to such 
                   further notice, oversight and considerations of safety as 
                   customarily apply under such circumstances; and

         8.3.2     Transportation charges and terminal exit fees associated with
                   transport of oil from or attributable to the Segregated Lease
                   through Chevron Pipe Line Company's common carrier pipeline
                   system from Main Pass 299B platform to Main Pass 69 into and
                   through Chevron Pipe Line Company's Empire Terminal. Seller,
                   however, agrees to reimburse Buyer for a certain portion of
                   transportation charges and exit fees, in the manner and in 
                   the amounts set forth in Exhibit "H" attached hereto.

         The parties understand and agree that Buyer, separately and 
         independently of this transaction, shall make its own arrangements 
         with Chevron Pipe Line Company for metering, transportation and 
         delivery of production through the said system and for tying into 
         said system.


    8.4  PIPELINE ACCESS.

         8.4.1     For purposes of this Section 8.4, the terms "sweet crude oil"
                   and "sour crude oil" are used to describe oil produced 
                   from the Retained Lease and from the Segregated Lease, 
                   respectively The parties do not intend to indicate any 
                   particular characteristics of either oil, the terms being 
                   merely a convenient means of relative comparison and 
                   reference.

         8.4.2     If requested by Chevron Pipe Line Company ("CPL"), Seller 
                   will notify CPL in writing that Seller has no objection to 
                   CPL's use of the existing 10-inch O.D. pipeline from Main 
                   Pass 299B platform to Main Pass 69 for transportation of 
                   the sour crude oil to be produced from the Segregated 
                   Lease. Further, Seller agrees to provide Buyer with such 
                   platform space on Main Pass 299B platform as is reasonably 
                   required for the tie-in of production to CPL's pipeline 
                   system, subject to such mutually agreeable terms and 
                   conditions as customarily apply under such circumstances.

         8.4.3     The parties contemplate that sweet crude oil produced and 
                   saved from the Retained Lease and other leases in the 
                   area, and sour crude oil produced and saved from the 
                   Segregated Lease, will be transported by CPL in separate 
                   pipelines from platforms on Main Pass Block 299 to Main 
                   Pass 69, and that the sour crude oil will be "batched" 
                   from Main Pass 69 to the Empire Terminal. The parties 
                   further understand and acknowledge CPL's role in the 
                   determination of which facilities shall be used for 
                   transportation of crude oil.

                   
    8.5  CALL ON OIL.  From time to time and at any time, Seller shall have the
         option, but not the obligation, to purchase or designate a purchaser
         financially acceptable to Buyer of the oil produced from or 
         attributable to the Segregated Lease. If purchased by Seller or a 
         designee, such crude oil would be delivered to a sales point 
         designated by Seller or its designee, which sales point shall be on 
         CPL's system and shall never be beyond the outermost flange of CPL's 
         Empire Terminal located in 


                                      12
<PAGE>

         Plaquemines Parish, Louisiana, unless the parties mutually agree 
         otherwise. The price to be paid to Buyer shall be the higher of (1) 
         fair market value for oil of like gravity and quality, or (2) the 
         price offered to Buyer from a bona fide third party in a written 
         offer by a third party, non-affiliated purchaser ready and able to 
         purchase, which offer Buyer is willing to accept, with comparable 
         terms and conditions. Buyer shall notify Seller in writing of any 
         such bona fide offer, giving the terms and conditions of such 
         acceptable offer.  Upon receiving such notice, Seller shall have ten 
         (10) days to elect to purchase such oil on the same terms and 
         conditions as contained in the bona fide offer. Further, Seller and 
         Buyer agree that in the event Buyer receives at any time and from 
         time to time such a bona fide offer from a third party to purchase 
         Buyer's crude oil at a price higher than that otherwise provided for 
         pursuant to this Section 8.5, Buyer may furnish Seller a copy of 
         such offer, and Seller shall have ten (10) days from receipt of such 
         offer either to agree to pay said higher price or to release Buyer's 
         oil production for sale to such third party in accordance with such 
         offer, including the term thereof.  In no event, however, shall 
         Seller be obligated to discontinue purchase of such crude oil sooner 
         than the first day of the month on or following the thirtieth (30th) 
         day following receipt of such bona fide offer. If at any time and 
         from time to time Seller is purchasing such crude oil hereunder, the 
         purchase of such crude oil by Seller shall be terminable at Seller's 
         option with at least ninety (90) days' prior written notice to 
         Buyer, such termination to be effective on the first day of the 
         calendar month on or following the end of such 90-day notice period, 
         or upon the expiration of the term theretofore offered by a third 
         party and matched by Seller, whichever is later: If purchased by 
         Seller or a designee, Buyer shall be obligated, at its sole cost and 
         expense, to deliver the oil to Seller at standard sour crude 
         pipeline quality, limited to three percent (3%) sulphur by weight 
         and fifty parts per million (50 ppm) hydrogen sulphide.
         
    8.6  ANTITRUST REVIEW. Seller and Buyer recognize that they have been 
         advised that the Federal Trade Commission has granted an early 
         termination of the thirty (30) day waiting period required under the 
         Hart-Scott-Rodino Antitrust Improvements Act of 1976. Each party 
         hereto acknowledges that it has satisfied itself that its 
         obligations under the Hart-Scott-Rodino Antitrust Improvements Act 
         of 1976 have been fulfilled.

    8.7  GAS CONTRACT.  Gas production from the Segregated Lease has been
         permanently released by Southern Natural Gas Company ("Southern") from 
         an Omnibus Contract entered into between Southern and Seller 
         effective January 1, 1988. The Omnibus Contract covered gas 
         previously sold to Southern under long-term interstate contract 
         which were terminated and abandoned under FERC Order No. 490.

    8.8  F.E.R.C. 500.  Any assignment of the Segregated Lease shall be subject 
         to the following provision:

         It is understood that interstate pipelines may refuse to transport 
         under 18 C.F.R. Part 284 gas produced from the properties hereby 
         assigned unless Seller agrees to offer take-or-pay or take-and-pay 
         credit to such pipelines, and the parties hereby agree that Seller 
         may withhold such an offer at its sole discretion, even if the 
         result is to completely bar Buyer's gas from the interests hereby 
         assigned from open access transportation in such pipelines. 
         Notwithstanding the foregoing, Seller agrees to execute offers of 
         credit necessary to render the assigned gas eligible for open access 
         transportation if Seller determines, in its sole discretion, that 
         such gas is exempt from crediting pursuant to FERC rules and 
         regulations or that Seller can otherwise execute such offers of 
         credit without risk of adverse economic consequences to Seller. Any 
         offers of credit executed by Seller pursuant to this provision shall 
         be limited in scope or term as Seller deems necessary.

    8.9  PROVISION OF DATA.  Seller shall have the right to receive from Buyer, 
         at no charge to Seller, all basic data and test results obtained in 
         the course of drilling, testing, evaluating and producing on, in or 
         under the Segregated Lease, to which no proprietary interpretive 
         notes, marks or comments have been added and exclusive of any 
         proprietary extrapolations derived therefrom ("Data").  Seller shall 
         furnish Buyer, at no charge to Buyer, any such Data obtained from 
         Seller's test well drilled on and in the 

                                      13
<PAGE>


         Segregated Lease, which is reasonably necessary to qualify said well 
         as producible under 30 CFR Section 250.11. All such Data which is 
         provided by one party to the other party pursuant to the provisions 
         of this Section 8.9 shall be maintained by the receiving party on a 
         confidential basis in accordance with the provision of Section 8.18.
         
    8.10 LOCATION AND/OR RELOCATION OF FLOWLINES OR FACILITIES.

         8.10.1    Should any of Buyer's operations require or reasonably
                   necessitate the removal, replacement, modification or 
                   relocation of any presently existing flowlines or 
                   facilities owned and operated by Seller or an affiliate of 
                   Seller; including but not limited to CPL, then such 
                   removal, replacement, modification or relocation shall be 
                   accomplished at Buyer's sole cost, risk and expense.

         8.10.2    Seller shall not locate any new flowlines or facilities on 
                   the surface area extent encompassed by the Segregated 
                   Lease without Buyer's prior written consent.

         8.10.3    It is understood that it will be necessary for Buyer to 
                   install flowlines and facilities on the surface area 
                   encompassed by the Retained Lease. Prior to installation 
                   of any such flowlines or facilities, Buyer shall consult 
                   with Seller in an effort to minimize interference with 
                   Seller's current and future operations. Seller shall not 
                   unreasonably withhold consent to such installations, it 
                   being understood that final approval for any such 
                   installations is vested in the MMS.

    8.11 PUBLICITY.  Except as modified by Section 8.18, Seller and Buyer shall
         jointly coordinate the timing and substance of any press releases or
         publicity concerning the transactions contemplated by this Agreement.

    8.12 ASSIGNMENT.  Buyer or Seller may not assign this Agreement or delegate 
         any duties hereunder without the prior written consent of the other, 
         which consent shall not be unreasonably withheld. Such assignment or 
         delegation shall not relieve the assigning party of liability for 
         the performance of its duties and obligations hereunder, and any 
         such assignment shall contain the express assumption by the assignee 
         of all duties and obligations incumbent on its assignor pursuant to 
         this Agreement, the performance of which such assignor guarantees. 
         The terms and conditions of this Agreement shall be real rights 
         attached to and appendages running with the interests in the 
         Segregated Lease and Physical Assets covered and affected by this 
         Agreement, and shall be binding upon and inure to the benefit of the 
         parties hereto, their respective successors and assigns, and their 
         successors and assigns.

         The following shall not be considered a violation of this Section 8.12:

         8.12.1    The assignment by Freeport of an undivided one-fourth (1/4th)
                   interest in this Agreement to IMC Fertilizer, Inc., a 
                   Delaware corporation ("IMC"), and the assignment by 
                   Freeport of an undivided one-sixth (1/6th) interest in 
                   this Agreement to Felmont Oil Corporation, a Delaware 
                   corporation ("Felmont"). In the event of such assignments, 
                   Freeport, IMC and Felmont shall assume, solidarily with 
                   each other, all obligations and liabilities provided for 
                   in Section 2.2 hereof except as may be otherwise provided 
                   with respect to Section 2.3 hereof and such parties, 
                   severally and to the extent of their respective interests, 
                   shall defend and indemnify Seller in accordance with the 
                   provisions of Section 2.3 hereof.

         8.12.2    The designation and appointment of Freeport as operator and 
                   of Freeport-McMoRan Oil & Gas Company as acting operator.

         8.12.3    The assignment by Buyer or Seller to an affiliate or 
                   subsidiary, or the execution of a mortgage, deed of trust, 
                   financing statement or other instrument for borrowing 
                   purposes, 

                                      14
<PAGE>


                   provided that any such instrument for financing purposes 
                   shall be subordinate to the terms and provisions of this 
                   Agreement.

    8.13 RIGHT TO AUDIT.  Seller shall have the right to question the
         appropriateness of the payments made to Seller by Buyer pursuant to 
         Section 3 hereof and of charges for partial reimbursement of 
         transportation costs incurred by Buyer pursuant to Section 8.3.2 
         hereof including without limitation the figures on which such 
         payments or charges were based, the amounts deducted therefrom, and 
         the calculation thereof.  Seller shall have the right, either itself 
         or by an accounting firm of Seller's choosing, to audit Buyer's 
         books and records to confirm or question the correctness of such 
         payments or charges, together with subsequent adjustments thereto, 
         during normal business hours and with no less than thirty (30) days' 
         prior written notice to Buyer. It is provided, however, that any 
         payment, charge or adjustment shall be considered correct and 
         appropriate if not challenged by Seller in writing within two (2) 
         years after the date the payment or invoice for the charge was 
         received by Seller, or within two (2) years after Seller's receipt 
         of notice of a payment adjustment, as applicable. All statements and 
         records shall be maintained for two (2) years after payments have 
         been made.

         Buyer shall have the right to audit Seller's books and records, 
         within the above time frame, to confirm the accuracy and 
         appropriateness of those costs estimated on Exhibit "B" and billed 
         to Buyer in accordance with Section 2.1.2 of this Agreement.
         
    8.14 CONFLICT OF INTEREST.  Buyer and Seller, for themselves and their
         directors, employees and agents, acknowledge that they are familiar 
         with and will comply with each other's Conflict of Interest 
         policies. Each party shall promptly notify the other party of any 
         violation of this Section 8.14, and any consideration received by a 
         party as a result of such violation shall be paid over or credited 
         to the other party. Each party, or its designated representative(s), 
         may audit, for reasonable cause, any pertinent records of the other 
         party for the sole purpose of determining whether there has been 
         compliance with this Section 8.14.

    8.15 TERM. This Agreement shall remain in force and effect for so long as 
         the Segregated Lease, or any extension, renewal or replacement 
         thereof remains in effect, and as long thereafter as necessary to 
         achieve full performance of all obligations assumed by the Buyer and 
         Seller hereunder.
         
    8.16 ENTIRE AGREEMENT.  As used herein, the term "this Agreement" includes 
         not only this Asset Sale Agreement but also all exhibits referred to 
         herein, which exhibits are hereby incorporated by reference for all 
         purposes. This Agreement constitutes the entire agreement between 
         Seller and Buyer with respect to the transactions contemplated 
         herein, and supersedes all prior oral or written agreements, 
         commitments, understandings, or information otherwise furnished by 
         Seller to Buyer with respect to such matters; provided, however, 
         that certain Agreement of Indemnity dated as. of the date of 
         Closing, by and between Chevron U.S.A. Inc. and Freeport-McMoRan 
         Inc. is not merged herein and survives the execution hereof. No 
         amendment shall be binding unless in writing and signed by 
         representatives of both parties. Headings used in this Agreement are 
         only for convenience of reference and shall not be used to define 
         the meaning of any provision. This Agreement is for the benefit of 
         Seller and Buyer only and not for the benefit of any other party.

    8.17 SURVIVAL.  The terms and provisions of this Agreement shall survive any
         assignment, pledge or delegation of any right, duty or obligation 
         covered and affected hereby.

    8.18 CONFIDENTIALITY . The contents of this Agreement, and any notes, 
         summaries, compilations, analyses or other material derived from 
         this Agreement, are confidential, and neither party shall release 
         any of such contents, notes, summaries, compilations, analyses or 
         other material to a third party without first obtaining the express 
         written consent of the other party hereto, except that this 
         prohibition shall not apply to disclosures:

         8.18.1    To any parent corporation, any subsidiary of any parent
                   corporation of or any subsidiary of either party hereto, or 
                   to any banking, accounting, engineering or other 
                   consultant firms to any party hereto, provided that any 
                   such recipient shall have first agreed in writing to be 
                   bound by the provisions of this Section 8.18;

         8.18.2    Required by law (including the rules and regulations of the
                   appropriate stock exchange);

         8.18.3    Of information that is already in the public domain through 
                   no fault of the party then disclosing it;

         8.18.4    Of information which either Buyer or Seller may have or 
                   hereafter lawfully may obtain from any party or parties who 
                   are legally entitled to such data.

         The parties furthermore agree that a party may disclose any of such 
         information to courts, governmental bodies or agencies or stock 
         exchanges if the disclosing party believes in good faith that such 
         disclosure is required by applicable law, regulation or regulatory

(hereinafter called the "Lessee").  In consideration of any cash payment 
heretofore made by the Lessee to the Lessor and in consideration of the 
promises, terms, conditions, and covenants contained herein, including the 
Stipulation(s) numbered 1 AND 3 attached hereto, the Lessee and Lessor agree 
as follows:

SEC. 1.   STATUTES AND REGULATIONS.  This lease is issued pursuant to the 
Outer Continental Shelf (OCS) Lands Act (43 U.S.C. 1331-1356, (1953)), as 
amended, and the regulations issued thereunder (30 CFR Part 256).  The lease 
is issued subject to the Act; all regulations issued pursuant to the Act and 
in existence upon the Effective Date of this lease; all regulations issued 
pursuant to the statute in the future which provide for the prevention of 
waste and conservation of the natural resources of the Outer Continental 
Shelf and the protection of correlative rights therein; and all other 
applicable statutes and regulations.

SEC. 2.   RIGHTS OF LESSEE.  The Lessor hereby grants and leases to the 
Lessee the exclusive right and privilege to drill for, develop, and produce 
sulphur and salt resources in the submerged lands of the Outer Continental 
Shelf containing approximately 4,560.81 acres (hereinafter referred to as the 
"leased area"), described as follows:

ALL OF BLOCK 299, MAIN PASS AREA, SOUTH AND EAST ADDITION, OCS LEASING MAP, 
LOUISIANA MAP NO. 10A.

<PAGE>


These rights include:

     (a)  the nonexclusive right to conduct within the leased area geological 
and geophysical exploration in accordance with applicable regulations;

     (b)  the nonexclusive right to drill water wells within the leased area, 
unless the water is part of geopressured-geothermal and associated resources, 
and to use the water produced therefrom for operations pursuant to the Act 
free of cost, on the condition that the drilling is conducted in accordance 
with procedures approved by the Director of the Minerals Management Service 
or the Director's delegate (hereinafter called the "Director"); and

     (c)  the right to construct or erect and to maintain within the leased 
area artificial islands, installations, and other devices permanently or 
temporarily attached to the seabed and other works and structures necessary 
to the full enjoyment of the lease, subject to compliance with applicable 
laws and regulations.


SEC. 3.   TERM.  This lease shall continue from the Effective Date of the 
lease for the Initial Period and so long thereafter as sulphur and/or salt 
are produced from the leased area in paying quantities, or drilling or well 
reworking operations, as approved by the Lessor, are conducted thereon, or as 
otherwise provided by regulations.


SEC. 4.   RENTALS.  The Lessee shall pay the Lessor, on or before the first 
day of each lease year which commences prior to a discovery in paying 
quantities of sulphur and/or salt on the leased area, a rental as shown on 
the face hereof.


SEC. 5.   MINIMUM ROYALTY.  The Lessee shall pay the Lessor, at the 
expiration of each lease year which commences after a discovery of sulphur 
and/or salt in paying quantities, a minimum royalty as shown on the face 
hereof or, if there is production, the difference between the actual royalty 
required to be paid with respect to such lease year and the prescribed 
minimum royalty if the actual royalty paid is less than the minimum royalty.


SEC. 6.   ROYALTY ON PRODUCTION.

     (a)  The Lessee shall pay a fixed royalty as shown on the face hereof in 
value of production saved, removed, or sold from the leased area.  Any Lessee 
is liable for royalty payments on sulphur and/or salt lost or wasted from a 
lease site when such loss or waste is due to negligence on the part of the 
operator of the lease, or due to the failure to comply with any rule or 
regulation, order, or citation issued under the Act.

     (b)  The value of production for purposes of computing royalty on 
production from this lease shall never be less than 5 percent of the gross 
production or value of the sulphur at the mine.  The value of production 
shall be the estimated reasonable value of the production as determined by 
the Lessor, due consideration being given to the highest price paid for a 
part or for a majority of sulphur and/or salt of like quality in the same 
general area, to the price received by the Lessee, to posted prices, and to 
other relevant matters. Except when the Lessor, in its discretion, determines 
not to consider special pricing relief from otherwise applicable Federal 
regulatory requirements, the value of production for the purposes of 
computing royalty shall not be deemed to be less than the gross proceeds 
accruing to the Lessee from the sale thereof.  in the absence of good reason 
to the contrary, value computed on the basis of the highest price paid or 
offered at the time of production in a fair and open market for the major 
portion of like quality sulphur produced and sold from the field or area 
where the leased area is situated will be considered to be a reasonable value.

     (c)  Royalties shall be due and payable by the last day of the next 
month following the month in which the sulphur and/or salt is produced, 
unless the Lessor prescribes a later date.


SEC. 7.   PAYMENTS.  The Lessee shall make all payments (rentals, royalties, 
and any other payments required by this lease) to the Lessor by electronic 
transfer of funds, check, draft on a solvent bank, or money order unless 
otherwise provided by regulations or by direction of the Lessor. Rentals, 
royalties, and any other payments required by this lease shall be made 
payable to the Minerals Management Service and tendered to the Director. 
Determinations made by the Lessor as to the amount of payment due shall be 
presumed to be correct and paid as due.


SEC. 8.   BONDS.  The Lessee shall maintain at all times the bond(s) required 
by regulation prior to the issuance of the lease and shall furnish such 
additional security as may be required by the Lessor if, after operations 
have begun, the Lessor deems such additional security to be necessary.


SEC. 9.   PLANS.  The Lessee shall conduct all operations on the leased area 
in accordance with approved exploration plans and approved development and 
production plans as are required by regulations.  The Lessee may depart from 
an approved plan only as provided by applicable regulations.


SEC. 10.  PERFORMANCE.  The Lessee shall comply with all regulations and 
Orders.  After due notice in writing, the Lessee shall drill such wells and 
produce at such rates as the Lessor may require in order that the leased area 
or any part thereof may be properly and timely developed and produced in 
accordance with sound operating principles.

<PAGE>


SEC. 11.  SAFETY REQUIREMENTS. The Lessee shall:

     (a)  maintain all places of employment within the leased area in 
compliance with occupational safety and health standards and, in addition, 
free from recognized hazards to employees of the Lessee or of any contractor 
or subcontractor operating within the lease area;

     (b)  maintain all operation within the leased area in compliance with 
regulations or orders intended to protect persons, property, and the 
environment on the Outer Continental Shelf; and

     (c)  allow prompt access, at the site of any operation subject to safety 
regulations, to any authorized Federal inspector and shall provide any 
documents and records which are pertinent to occupational or public health, 
safety, or environmental protection as may be requested.


SEC. 12.  SUSPENSION AND CANCELLATION.

     (a)  The Lessor may suspend or cancel this lease pursuant to Section 5 of 
the Act, and compensation shall be paid when provided by the Act.

     (b)  The lessor may, upon recommendation of the secretary of Defense, 
during a state of war or national emergency declared by Congress or the 
President of the United States, suspend operations under the lease, as 
provided in section 12(c) of the Act, and just compensation shall be paid to 
the Lessee for such suspension.


SEC. 13.  INDEMNIFICATION.  The Lessee shall indemnify the Lessor for, and 
hold it harmless from, any claim, including claims for loss or damage to 
property or injury to person caused by or resulting from any operation on the 
leased area conducted by or on behalf of the Lessee.  However, the Lessee 
shall not be held responsible to the Lessor under this section for any loss, 
damage, or injury caused by or resulting from:

     (a)  negligence of the Lessor other than the commission or omission of a 
discretionary function or duty on the part of a Federal Agency whether or not 
the discretion involved is abused; or

     (b)  the Lessee's compliance with an order or directive of the Lessor 
against which an administrative appeal by the Lessee is filed before the 
cause of action for the claim arises and is pursued diligently thereafter.


SEC. 14.  PURCHASE OF PRODUCTION.  In time of war or when the President of 
the United States shall so prescribe, the Lessor shall have the right of 
first refusal to purchase at the market price all or any portion of the 
sulphur and/or salt produced from the leased area, as provided in Section 
12(b) of the Act.


SEC. 15.  EQUAL OPPORTUNITY CLAUSE.  During the performance of this lease, 
the Lessee shall fully comply with paragraphs (1) through (7) of section 202 
of Executive Order 11246, as amended (reprinted in 41 CFR 60-1.4(a)), and the 
implementing regulations which are for the purpose of preventing employment 
discrimination against persons on the basis of race, color, religion, sex, or 
national origin.  paragraphs (1) through (7) of section 202 of Executive 
Order 11246, as amended, are incorporated in this lease by reference.


SEC. 16.  CERTIFICATION OF NONSEGREGATED FACILITIES.  By entering into this 
lease, the Lessee certifies, as specified in 41 CFR 60-1.8, that it does not 
and will not maintain or provide for its employees any segregated facilities 
at any of its establishments and that it does not and will not permit its 
employees to perform their services at any location under its control where 
segregated facilities are maintained.  As used in this certification, the 
term "segregated facilities" means, but is not limited to, any waiting rooms, 
work areas, restrooms and washrooms, restaurants and other eating areas, 
timeclocks, locker rooms and other storage or dressing areas, parking lots, 
drinking fountains, recreation or entertainment areas, transportation, and 
housing facilities provided for employees which are segregated by explicit 
directive or are in fact segregated on the basis of race, color, religion, or 
national origin, because of habit, local custom, or otherwise.  The Lessee 
further agrees that it will obtain identical certifications from proposed 
contractors and subcontractors prior to award of contracts or subcontracts 
unless they are exempt under 41 CFR 60-1.5.


SEC. 17.  RESERVATIONS TO LESSOR.  All rights in the leased area not 
expressly granted to the Lessee by the Act, the regulations, or this lease 
are hereby reserved to the Lessor.  Without limiting the generality of the 
foregoing, reserved rights included:

     (a)  the right to authorize geological and geophysical exploration in 
the lease area which does not unreasonably interfere with or endanger actual 
operations under the lease, and the right to grant such easements or 
rights-of-way upon, through, or in the leased area as may be necessary or 
appropriate to working of other lands or to the treatment and shipment of 
products thereof by or under authority of the Lessor;

     (b)  the right to grant leases for any minerals other than sulphur 
and/or salt within the leased area, except that operations under such leases 
shall not unreasonably interfere with or endanger operations under this lease;

     (c)  the right, as provided in section 12(d) of the Act, to restrict 
operations in the leased area or any part thereof which may be designated by 
the Secretary of Defense, with

<PAGE>


approval of the President, as being within an area needed for national 
defense and, so long as such designation remains in effect, no operations may 
be conducted on the surface of the leased area or the part thereof included 
within the designation except with the concurrence of the Secretary of 
Defense.  If operations or production under this lease within any designated 
area are suspended pursuant to this paragraph, any payments of rentals and 
royalty prescribed by this lease likewise shall be suspended during such 
period of suspension of operations and production, the term of this lease 
shall be extended by adding thereto any such suspension period, and the 
Lessor shall be liable to the Lessee for such compensation as is required to 
be paid under the Constitution of the United States.


SEC. 18.  TRANSFER OF LEASE. The Lessee shall file for approval with the 
appropriate field office of the Minerals Management Service any instrument of 
assignment or other transfer of this lease, or any interest therein, in 
accordance with applicable laws and regulations.


SEC. 19.  SURRENDER OF LEASE. The Lessee may surrender this entire lease or 
any officially designated subdivision of the leased area by filing with the 
appropriate field office of the Minerals Management Service a written 
relinquishment, in triplicate, which shall be effective as of the date of 
filing.  No surrender of this lease or of any portion of the leased area 
shall relieve the Lessee or its surety of the obligation to pay all accrued 
rentals, royalties, and other financial obligations or to abandon all works 
on the area to be surrendered in a manner satisfactory to the Director.


SEC. 20.  REMOVAL OF PROPERTY ON TERMINATION OF LEASE.  Within a period of 1 
year after termination of this lease in whole or in part, the Lessee shall 
remove all devices, works, and structures from the premises no longer subject 
to the lease in accordance with applicable regulations and orders of the 
Director.  However, the Lessee may, with the approval of the Director, 
continue to maintain devices, works, and structures on the leased area for 
drilling or producing on other Leases.


SEC. 21.  REMEDIES IN CASE OF DEFAULT.


     (a)  Whenever the Lessee fails to comply with any of the provisions of 
the Act, the regulations issued pursuant to the Act, or the terms of this 
lease, the lease shall be subject to cancellation in accordance with the 
provisions of section 5(c) and (d) of the Act and the Lessor may exercise any 
other remedies which the Lessor may have, including the penalty provisions of 
section 24 of the Act.  Furthermore, pursuant to section 8(o) of the Act, the 
Lessor may cancel the lease if it is obtained by fraud or misrepresentation.

     (b)  Nonenforcement by the Lessor of a remedy for any particular 
violation of the provisions of the Act, the regulations issued pursuant to 
the Act, or the terms of this lease shall not prevent the cancellation of 
this lease or the exercise of any other remedies under paragraph (a) of this 
section for any other violation or for the same violation occurring at any 
other time.


SEC. 22.  UNLAWFUL INTEREST.  No member of, or Delegate to, Congress, or 
Resident Commissioner, after election or appointment, or either before or 
after they have qualified, and during their continuance in office, and no 
officer, agent, or employee of the Department of the Interior, except as 
provided in 43 CFR Part 20, shall be admitted to any share or part in this 
lease or derive any benefit that may arise therefrom.  The provisions of 
Section 3741 of the Revised Statutes, as amended, 41 U.S.C. 22, and the Act 
of June 25, 1948, 62 Stat. 702, as amended, 18 U.S.C. 431-433, relating to 
contracts made or entered into or accepted by or on behalf of the United 
States, form a part of this lease insofar as they may be applicable.


SEC. 23.  SPECIAL PROVISIONS.

     (a)  Any lease issued for an initial period of 10 years will be canceled 
after 5 years, following notice pursuant to the Outer Continental Shelf Lands 
Act, where drilling of an exploratory well has not been commenced before the 
end of the 5th year, or if the well has not been drilled in conformance with 
the approved exploration plan criteria, or if there is not a suspension of 
operations in effect.

     (b)  The Lessee is granted the exclusive right to drill salt wells 
within the leased area and to use the salt produced therefrom for 
sulphur-mining operations pursuant to the Act free of royalty on the lease, 
on the condition that the drilling is conducted in accordance with procedures 
approved by the Director.

     (c)  The Lessee shall pay no royalty on salt produced and consumed or 
otherwise used on the lease for the production of sulphur.  The Lessee shall 
pay a fixed royalty of 5% at the mine for any salt produced and used or 
otherwise disposed of off the leased area for purposes other than sulphur 
production.

STIPULATION NO. 1--PROTECTION OF ARCHAEOLOGICAL RESOURCES

(1)  "Archaeological resource" means any prehistoric or historic district, 
site, building, structure, or object (including shipwrecks); such term 
includes artifacts, records, and remains which are related to such a 
district, site, building, structure, or object (Section 301(5), National 
Historic Preservation Act, as amended, 16 U.S.C. 470w(5)).  "Operations" 
means any drilling, mining, or construction or placement of any structure for 
exploration, development, or production of the lease.

(2)  If the Regional Director (RD) believes an archaeological resource may 
exist in the lease area, the RD will notify the lessee in writing.  The 
Lessee shall then comply with subparagraphs (a) through (c).

     (a)  Prior to commencing any operations, the lessee shall prepare a 
report, as specified by the RD, to determine the potential existence of any 
archaeological resource that may be affected by operations.  The report, 
prepared by an archaeologist and a geophysicist, shall be based on an 
assessment of data from remote-sensing surveys and of other pertinent 
archaeological and environmental information.  The lessee shall submit this 
report to the RD for review.

     (b)  If the evidence suggests that an archaeological resource may be 
present, the lessee shall either:

          (i)  Locate the site of any operation so as not to adversely affect 
the area where the archaeological resource may be; or

         (ii)  Establish to the satisfaction of the RD that an archaeological 
resource does not exist or will not be adversely affected by operations.  
This shall be done by further archaeological investigation, conducted by an 
archaeologist and a geophysicist, using survey equipment and techniques 
deemed necessary by the RD.  A report on the investigation shall be submitted 
to the RD for review.

     (c)  If the RD determines that an archaeological resource is likely to 
be present in the lease area and may be adversely affected by operations, the 
RD will notify the lessee immediately.  The lessee shall take no action that 
may adversely affect the archaeological resource until the RD has told the 
lessee how to protect it.

(3)  If the lessee discovers any archaeological resource while conducting 
operations on the lease area, the lessee shall report the discovery 
immediately to the RD.  The lessee shall make every reasonable effort to 
preserve the archaeological resource until the RD has told the lessee how to 
protect it.

STIPULATION NO. 3--HYDROCARBON DISCOVERIES STIPULATION

Sulphur and salt leases are granted separately from oil and gas leases. 
Therefore, any hydrocarbons discovered by the sulphur and salt lessee cannot 
be produced under this lease.  If the lessee discovers hydrocarbons while 
conducting sulphur and salt operations on the lease area, the lessee shall 
report the discovery immediately to the Regional Director (RD).  If the RD 
determines that the discovery is significant and the Director determines that 
release of the information is necessary for the proper development of the 
filed or area, then a public announcement of the significant hydrocarbon 
discovery will be made pursuant to 30 CFR 250.3.

                              II.  INTERESTS OF PARTIES

    2.1  Except as otherwise provided in this Agreement, the Property shall 
be owned as shown on Exhibit "A" attached hereto and made a part hereof for 
all purposes.

    2.2  Subject to the rights of Chevron U.S.A. Inc. to purchase production 
from the Lease and to the other provisions hereof, each Party shall own and 
shall have the right to receive in kind and to separately dispose of its 
proportionate share of the oil and gas production from the Lease which shall 
be delivered to such Party, at its option, at the outlet of the production 
facilities on the production facilities platform(s); or to its credit in the 
pipeline to which the well or wells or production facilities platform(s) may 
be connected. Any extra expenditure incurred in the receiving in kind or 
separate disposition by any Party of its proportionate share of the 
production shall be borne by such Party. Where a Party hereto elects to 
receive in kind or separately dispose of its share of production, such Party 
shall have the obligation to make payment of all royalties and other burdens 
(including the Production Payment reserved or owned by Chevron U.S.A. Inc.) 
attributable to the share of production taken or disposed of by such electing 
Party and such Party shall furnish Operator with full information regarding 
such royalty and other payments. In the event that a Party does not elect to 
receive in kind or separately dispose of its share of production and such 
share is sold by Operator pursuant to the provisions of Paragraph 2.3, 
Operator shall make the royalty and other payments on production attributable 
to such share, but shall not be liable to the party(s) that owns such share 
for any good faith failure to make any such payment properly or punctually.

    2.3  In the event any Party shall fail to take in kind or separately 
dispose of its proportionate share of production from the Lease, Operator 
shall have the right, but not the obligation to purchase such production or 
sell it to others for the time being, at the best price obtainable which 
shall in no event be less than the price which Operator receives for its 
portion of the production from the Lease.  Operator's authority to sell such 
production shall be revocable at the will of the owner thereof, and the term 
of any contract for the sale of such production shall be for no longer period 
than is commensurate with the minimum needs of the industry under the 
particular circumstances and in no event longer than one year. Any such 
purchase or sale by Operator shall be subject always to the right of the 
owner of the production to exercise at any time its right to take in kind, or 
separately dispose of, its share of all production not previously delivered 
to a purchaser. Notwithstanding the foregoing, the Parties agree to apply and 
be bound by the terms and provisions of the Gas Balancing Agreement in the 
form attached hereto as Exhibit "C" and made a part hereof for all purposes.

    2.4  Each Party shall execute all division orders and contracts of sale 
relating to its interest in production from the Lease, or authorize execution 
by Operator on its behalf; provided, however, no Party shall be forced to 
share an available market with any other Party hereto.

                               III.  COSTS AND EXPENSES

    3.1  All costs, expenses and liabilities accruing or resulting from the 
operation and/or ownership of the Property pursuant to this Agreement shall 
be determined in accordance with the applicable provisions of this Agreement 
and shall be shared and borne (except as hereinafter provided) by the Parties 
hereto in the percentages stated in Exhibit "A" hereof (such percentages 
referred to therein and herein as the "Participating Interests").

                                  2
<PAGE>

    3.2  Operator may, at any time, require each Non-operator to pay in 
advance, its proportionate part of reasonable expenditures for the 
development, operation, abandonment and reclamation of the Property for the 
Joint Account (as that term is defined in Exhibit "B" hereto) for the 
succeeding month's operation. Operator shall adjust each monthly billing to 
reflect advances received from the Non-operators. Each Non-operator shall pay 
its proportion of all bills within thirty (30) days after receipt or before 
the first day of the month for which the advance payment is made, whichever 
is later. If such payment is not so made when due, the amount thereof, or any 
unpaid balance, shall bear interest at the rate as provided in Paragraph 3.3. 
Adjustment between estimated expenditures for which advance payments are 
made, and the actual expenditures, shall be made by Operator monthly.

    3.3  Unpaid sums, until paid, shall bear interest at the rate of two 
percent (2%) over the prime rate of interest from time to time charged by 
Manufacturers Hanover Trust Company, but in no event more than the maximum 
rate permitted by applicable law; provided however, if Louisiana is the 
applicable law then the interest rate shall be 2% over the prime rate of 
interest from time to time charged by Manufacturers Hanover Trust Company.

                                    IV.  OPERATOR

    4.1  Freeport shall act as Operator of the Property and subject to the 
terms, conditions, and provisions herein set forth, shall have complete 
charge and control thereof and the management, operation, exploration and 
development thereof for the Joint Account of the Parties hereto. Freeport, 
IMC and Felmont are concurrently entering into a separate agreement effective 
as of the date of this Agreement and entitled "Agreement Designating Acting 
Operator" whereby Freeport-McMoRan Oil & Gas Company ("FMOG"), a Delaware 
corporation and an affiliate of Freeport is designated as the "Acting 
Operator" for the Property, pursuant to the terms and conditions of said 
agreement. Such designation of FMOG as Acting Operator shall not constitute a 
resignation or termination by Freeport of its duties as Operator hereunder. 
The Parties hereto recognize and agree that, as a result of FMOG being 
designated as Acting Operator pursuant to such separate agreement, costs and 
expenses otherwise paid hereunder to Freeport as Operator shall be paid to 
FMOG as Operator as long as FMOG is Acting Operator under such separate 
agreement and that Freeport, as an owner of interest in this Agreement, shall 
make payments to FMOG for its proportionate share of such costs and expenses, 
including the overhead charges provided for in the Exhibit "B" attached 
hereto and made a part hereof for all purposes. Should Operator or any 
successor Operator hereunder (1) dissolve, liquidate or terminate its 
corporate existence or partnership structure, (2) become insolvent, bankrupt, 
or subject to receivership, (3) no longer own an interest in the Property or 
(4) fail materially to perform its duties hereunder, it shall cease to be 
Operator hereunder effective as of the date a new Operator is elected. Change 
of the partnership name or structure of Operator or transfer of Operator's 
interest to any subsidiary, parent, affiliate, successor corporation or 
surviving corporation or partnership in consolidation or merger, shall not 
automatically cause the removal of Operator.

    4.2  Operator or any successor Operator may resign its duties as Operator 
hereunder; provided, however, that the Non-operators shall written notice of 
such resignation at least sixty (60) days prior to the effective date of 
resignation.

    4.3  In the event the total of the Participating Interests owned by 
Operator and/or any Affiliate or Affiliates of Operator should at any time 
fall below a percentage equal to 50%, less the lowest percentage 
Participating Interest owned by a Non-operator at such time, the 
Non-operators shall have the right to remove the Operator without cause upon 
30 days written notice, provided such removal is by the unanimous agreement 
of the Non-operators.

    4.4  Should any Operator or any successor Operator for any cause cease to 
be Operator hereunder, a successor Operator shall be designated by the vote 
of the Parties owning a majority in interest. If the removed Operator fails 
to vote or votes only to succeed itself, the successor Operator shall be 
selected by the affirmative vote of Non-operators having a majority of the 
interest in the Property remaining after excluding the interest of the 
removed Operator. Should Operator or any successor Operator hereunder cease 
to be Operator for any cause, its rights, titles and interests in the 
Property shall be unaffected by such cessation, but it shall thereupon become 
one of the Non-operators hereunder and shall henceforth be bound by the terms 
and provisions hereof, as a Non-operator.

    4.5  Any Party hereto designated as Operator to succeed the Operator 
herein named or any successor Operator shall thereupon succeed to all the 
duties, powers, obligations, rights and authority given to the Operator 
herein named with respect to all operations of every kind thereafter 
conducted on or in respect of the Property. All Equipment acquired for the 
account of the Parties and devoted to operations hereunder shall be 
surrendered promptly to any appointed successor Operator.

                               V.  ACCOUNTING PROCEDURE

    5.1  All costs incurred in the operations hereunder and all credits 
received shall be charged or credited to the account of the Parties hereto in 
accordance with the provisions of Exhibit "B" attached hereto and made a part 
hereof; provided, however, that if any provision of said Exhibit "B" 
conflicts with any provision of this Agreement, this Agreement shall control.

                          VI.  MINIMUM ROYALTIES AND RENTALS

    6.1  Operator shall pay and charge to the Joint Account the rental, 
minimum royalty, and any similar payments provided for in the Lease.

                             VII.  EXPENDITURE LIMITATION

    7.1  No operation shall be conducted on or in respect of the Property 
except as hereinafter provided for by this Agreement. No expenditure shall be 
made by Operator for the Joint Account in developing and operating the 
Property or for capital investment in excess of $100,000 unless made pursuant 
to a Work Plan and Budget approved as provided in Paragraphs 8.5 or 8.6 below 
or in connection with an operation or proposal approved pursuant to the 
non-consent provisions of Article VIII hereof, except in the case of expenses 
reasonably incurred in safeguarding life and property in case of a blowout, 
explosion, fire, flood, storm, hurricane, catastrophe or other sudden 
emergency.

    7.2  Upon written request, a copy of each of Operator's internal 
Authorizations for Expenditure which covers a gross amount of TWENTY-FIVE 
THOUSAND DOLLARS ($25,000.00) or more for the Joint Account shall be 
furnished to Non-operators for information.

                  VIII.  POLICY COMMITTEE AND WORK PLANS AND BUDGETS

    8.1  The Parties establish a Policy Committee to be composed of one 
representative designated by each Party.

         A representative designated pursuant to this Paragraph 8.1 shall 
serve until replaced by the Party that designated such representative. Each 
Party also may designate one or more alternates for any representative 
designated by it. An alternate shall exercise voting rights only in the event 
of a representative's absence. Each representative may bring to Policy 
Committee meetings such advisors as the representative deems necessary or 
desirable; however, such advisors shall have no right to vote on matters 
before the Policy Committee.

         Each Party promptly shall advise the other Parties in writing as to 
the names and addresses of its representative and alternate representative 
who shall have the authority to represent and bind the advising Party with 
respect to any matter to be acted upon by the Policy committee. A Party's 
representative or alternate representative may be changed from time to time 
upon written notice to the other Parties.

    8.2  The Operator will provide to the Non-operators and the members of 
the Policy Committee a proposed Work Plan and Budget for the following 
calendar year not later than September 15 of each year. As used herein the 
term "Work Plan" means a detailed program for Joint Operations to be 
conducted during a Budget Year, adopted pursuant to this Article VIII; the 
term "Budget" means a detailed projection of costs and expenses required for 
Joint Operations during a Budget Year; the term "Budget Year" means January 1 
to December 31, or such period as is mutually agreed upon; and the term 
"Joint Operations" shall have the meaning ascribed to such term in Exhibit 
"B" hereof. The 

                                  4
<PAGE>

designated representatives of Non-operators shall respond by October 15 of 
each year with the regular meeting to be held between October 15 and November 
1 of each year. Special meetings shall be called by the Operator as and when 
the Operator should deem necessary. Any of the other Parties to this 
Agreement shall have the right to call a special meeting provided that no 
such special meeting shall be called sooner than three months after the last 
such special meeting. During the fifth month of each Budget Year the Operator 
shall call an advisory meeting for the sole purpose of informing the Policy 
Committee of the progress of Joint Operations for the current Budget Year to 
date. The Parties and Operator shall attend all regular, special and advisory 
meetings of the Policy Committee. All meetings shall be held at Operator's 
offices, unless all Parties agree to another location. Written notice of the 
time and place of each regular, special and advisory meeting, shall be 
submitted by the Operator to the Parties, not less than 15 days before any 
such meeting, unless such requirement of notice is waived in writing by the 
Parties. The holding of any advisory meeting may be waived provided all 
Parties consent to such waiver.

         The designated representative, or alternate, of Operator shall act 
as chairman at all Policy Committee meetings. Each Party shall bear its own 
cost of attendance. If Operator deems it necessary for any personnel who are 
assigned duties in connection with the conduct of Joint Operations to attend 
any meeting, the additional cost incurred therefor shall be charged to the 
Joint Account.

    8.3  The annual Work Plan shall describe in reasonable detail (i) the 
maintenance, exploration, development and/or production, and abandonment and 
reclamation objectives for the Budget Year covered thereby; (ii) the work to 
be performed in attaining the objectives; (iii) the portion of the Lease on 
which Joint Operations are to be performed; (iv) the technical basis for the 
type of Joint Operation proposed; and (v) such other information as the 
Operator may deem appropriate or as reasonably requested by one (1) or more 
Non-operators. In addition to the foregoing:

         (a)  Work Plans involving development operations shall include: (i) any
         pertinent geological and engineering information; (ii) number, location
         and proposed depth of any wells proposed to be drilled; (iii) reworking
         operations on or abandonment of any well; and (iv) plans for the
         installation of necessary flowlines, facilities and/or platforms; and

         (b)  Work Plans involving production operations shall include: (i) 
         expected production of oil and gas; and (ii) unit costs of such 
         production.

         Each Budget shall describe in reasonable detail the anticipated 
costs to be incurred under the applicable Work Plan and the date or dates 
funds from the Parties are expected to be required.

    8.4  The Policy Committee shall approve all Work Plans and Budgets and 
supplements thereto and revisions thereof, settlement of claims and suits in 
accordance with the provisions of this Agreement, and shall have the right 
and authority to wind up the activities of the Joint Operations following 
termination of this Agreement.

    8.5  Only those Parties owning an interest in the Property of ten percent 
(10%) or more may vote on matters before the Policy Committee. Policy 
Committee approval of any matter requiring Policy Committee approval 
hereunder, shall require the vote of Operator and the vote of at least one 
other Party entitled to vote which is not an Affiliate of the Operator; 
provided, however, that if only one Party other than Operator should be 
entitled to vote then Policy Committee approval of any such matter shall 
require only the vote of Operator.

         With respect to any matter submitted by Operator for Policy 
Committee approval, should Operator be unable to obtain the vote of at least 
one other Party entitled to vote which is not an Affiliate of the Operator, 
then in such event all Parties entitled to vote shall continue good faith 
negotiations to resolve outstanding differences. In the event the Policy 
Committee is unable to secure approval of a proposed Work Plan and Budget 
within 60 days, the Operator shall submit an alternate proposed Work Plan and 
Budget. In any event, the Operator shall incur for the Joint Account such 
expenditures as it reasonably determines to be necessary for the continued 
maintenance of the Lease and shall be permitted to operate the Property at a 
level and in a manner which preserves the value thereof, to the extent that 

                                  5
<PAGE>

such expenditures and operations are not subject to the non-consent 
provisions of this Article VIII. No formal Policy Committee approval shall be 
necessary for such expenditures or for such operations.

         In lieu of deciding any matter at any meeting, the Policy Committee 
may act (a) by instrument(s) in writing signed by the representative of each 
interest owner, which instrument(s) (in one or more counterparts) shall be 
conclusively deemed to be the act of the Policy Committee, or (b) by 
telephone communication provided that such action is unanimous and is 
confirmed in writing by each Party or each Party's representative.

    8.6  The Initial Work Plan and Budget for calendar years 1990 and 1991 
has been submitted to the Non-operators prior to the execution of this 
Agreement and is attached hereto as Exhibit "E". By their execution of this 
Agreement, all Parties hereto hereby approve said initial Work Plan and 
Budget and, accordingly, the Operator is authorized to make the expenditures 
provided for therein. The Parties further recognize that certain of the 
expenditures included in such initial Work Plan and Budget have already been 
expended in anticipation of the execution of this Agreement and the approval 
of such expenditures is hereby confirmed.

    8.7  Operator shall have the sole right to propose Work Plans and Budgets 
and supplements and revisions thereto. Operator shall not be deemed to have 
exceeded any approved Work Plan and Budget provided the total of actual costs 
and expenses incurred by the implementation of such Work Plan and Budget does 
not exceed by more than fifteen percent the total costs and expenses 
authorized for such Work Plan and Budget; provided, however, if such actual 
costs and expenses will exceed such percentage of authorized costs and 
expenses, Operator shall be required to submit a revised Work Plan and Budget 
in respect of such excess costs and expenses for Policy Committee approval. 
Operator shall have discretion in deciding which costs and expenses shall or 
shall not be incurred for purposes of keeping costs and expenses of an 
approved Work Plan and Budget within the limits authorized therefor.  The 
Policy Committee shall consider all Work Plans and Budgets submitted by 
Operator pursuant to the provisions hereof and, except otherwise provided in 
Paragraph 8.5 above, shall take action thereon in accordance with Paragraph 
8.9 below. In the event that (1) the Operator has committed to the 
construction of a platform or related facilities, the drilling of a well, or 
any other operation, included in an approved Work Plan and Budget, (2) it 
subsequently develops that the cost of such operation when added to costs 
incurred pursuant to such approved Work Plan and Budget has exceeded ten 
percent (10%) of the total estimated cost of the approved Work Plan and 
Budget, (3) the Non-operators have declined to approve such excess 
expenditures in a supplemental or revised Work Plan and Budget submitted 
pursuant to Paragraph 8.8 below, and (4) the Operator under its commitment 
diligently pursues such operation, then such excess costs so expended or to 
be incurred by Operator shall be considered an approved budget expenditure in 
the Work Plan and Budget adopted for the succeeding year and paid by the 
Parties in the ordinary course of business as set out herein; provided, 
however, at any time subsequent to the beginning of such succeeding year, 
Operator may bill the Non-operators their unpaid respective shares of such 
expenditures made by Operator in conducting such operation in the preceding 
year, plus interest at the rate provided for in Paragraph 3.3 above on the 
amount so billed; provided further, however, such excess costs expended or 
incurred and paid by Operator pursuant to Item (4) of this sentence 
considered approved in the succeeding year's Work Plan and Budget shall not 
exceed fifteen percent (15%) of the total estimated cost of the said approved 
Work Plan and Budget for the preceding year and further provided, any 
supplemental or revised budget (or a portion thereof ) submitted pursuant to 
Item 3 of this sentence shall not be subject to the non-consent provisions of 
Article VIII.

    8.8  From time to time, Operator, pursuant to Paragraph 8.7 above, may 
propose supplemental or revised Work Plans and Budgets to the Policy 
Committee which shall consider and take action thereon in accordance with 
Paragraph 8.9 below. Any such supplement or revision shall be prepared as 
provided in Paragraph 8.3 above and shall be submitted to the Policy 
Committee as far in advance of implementing the supplemental or revised Work 
Plan and Budget as is reasonably practicable.

    8.9  The Policy Committee shall consult in a good faith effort either to 
approve or adopt each proposed Work Plan and Budget (or revision thereof or 
supplement thereto) as submitted, or to formulate an alternative Work Plan 
and Budget acceptable to the Parties.  Actions on all Work Plans and Budgets 
shall be taken as provided for in Paragraph 8.5 above. Once approved as 
provided in Paragraph 8.5 above, the annual Work Plan and Budget, any 
approved supplement thereto or any approved revision thereof, shall be 
binding on the Parties and shall be carried out by Operator. Notwithstanding 
the foregoing, in the event that the installation of a platform provided for 
in the Initial Work Plan and 

                                  6
<PAGE>
Budget has not been commenced prior to the end of 1992, then in such event 
such platform and any equipment related directly thereto as well as any wells 
proposed to be drilled therefrom shall ipso facto be deleted from the Initial 
Work Plan and Budget and the approval granted by Non-operators herein for 
such platform, related equipment and wells shall accordingly terminate and be 
of no further force and effect.

    8.10 The foregoing provisions of this Article VIII shall apply to 
platforms, any wells drilled therefrom and any other operations that are 
included in the Initial Work Plan and Budget for the calendar years 1990 and 
1991 ("the Initial Work Plan and Budget"). For the purposes of this Article 
VIII, an Extraordinary Operation is defined as (1) the setting of a platform 
and related facilities that is not included in the said Initial Work Plan and 
Budget, (2) the drilling of a well or wells (but not including salt water 
disposal wells) on any part of the Lease that are not included in the Initial 
Work Plan and Budget, (3) a proposal to conduct an enhanced oil recovery 
operation on the Lease, or (4) a proposal to make a capital expenditure (not 
including the cost of drilling a well) not included in the Initial Work Plan 
and Budget in excess of $1,000,000. For the purposes of the immediately 
preceding sentence, the phrase "not included in the Initial Work Plan and 
Budget" shall be deemed to include any operations which were included in the 
Initial Work Plan and Budget but are no longer included therein pursuant to 
the operation of Paragraphs 8.7 and 8.9 hereof . The foregoing provisions of 
Paragraphs 8.1 through 8.9 of this Article VIII shall also apply to 
Extraordinary Operations that are approved by all Parties. The following 
provisions of this Article VIII shall however apply to Extraordinary 
Operations that are not approved by all Parties.

    8.11 Without the consent of all Parties in interest, no Extraordinary 
Operation shall be conducted on the Property except as hereinafter provided 
for by this Agreement and the following provisions of this Article VIII will 
apply only to such Extraordinary Operations conducted on the Property. Once 
an Extraordinary Operation has been considered by the Policy Committee and 
has not received approval of all Parties, any Party, Operator or 
Non-Operator, may at any time thereafter propose such an operation.

    8.12 Such proposal shall be made to all Parties and, in the case of a 
well proposal, shall designate the surface and bottomhole location, the 
proposed depth, the sands or horizons expected to be penetrated and tested, 
the tentative programs for casing, surveying and testing the well, estimated 
cost and the portion thereof to be borne by each Party entitled to 
participate therein, and other relevant information and, in the case of a 
platform, the proposal shall include the estimated cost of designing, 
fabricating, transporting and installing such platform and any other 
information that may be related thereto and, in the case of a proposal to 
conduct an enhanced oil recovery operation, the proposal shall include 
detailed information relating thereto.

    8.13 (a)  Within thirty (30) days (60 days in the case of a platform 
proposal) after its receipt of such proposal and data to be used to make an 
election, each Party to whom the proposal was made may elect to participate 
in the proposed operation or operations to the extent of its interest as 
stated in the proposal, by giving notice thereof to the Operator. Failure to 
give timely notice of an election to participate shall constitute an election 
not to participate in the proposed operation. Operator shall notify each 
Party immediately of all of the elections which are made. Parties who elect 
not to participate are hereinafter each referred to as a "Non-participant" or 
collectively as "Non-participants".

    (b)  In the event fewer than all of the parties elect to participate, 
Operator shall by telex or other written notice advise the Parties electing 
to participate of the aggregate Participating Interests not participating and 
of the pro rata increase in participation which is available to those Parties 
which have elected to participate. Within 72 hours after receipt of such 
notice from the Operator, each such notified Party shall notify the Operator 
by telex or other written notice whether or not it will assume some or all of 
the obligations which would have been assumed by the Non-participants had 
they elected to participate. Failure to respond shall be deemed an election 
not to increase participation. If the Participating Parties elect to assume 
all of the obligations which would have been assumed by the Non-participants 
had they elected to participate, the Operator shall proceed with such 
operation for the account of and at the sole risk and expense and in the 
agreed percentages of those Parties electing to participate. If one or more 
of the Participating Parties do not agree to assume all of the obligations 
which would have been assumed by the Non-participants, the Operator shall not 
proceed with such operation and it will be considered as if no proposal had 
been made.

                                  7
<PAGE>

    8.14 In the event that there are proposals made hereunder to drill more 
than one well, the proposals shall take precedence in the order in which such 
proposals are made. Although a Party may propose more than one well or 
operation at the same time, the Parties receiving such proposal shall have 
the right to consent or not to consent separately as to each individual well 
or operation being proposed; provided however, that the response to all such 
wells or operations shall be made within the time period specified in Section 
8.13(a) hereof.

    8.15 If all Parties receiving the proposal elect to participate in such 
operation, it shall be conducted at the cost and risk of such Parties. If 
less than all such Parties elect to participate in such operation, the Party 
who proposed such operation and any Parties who elected to participate 
therein (herein called "Participating Parties" or "Participants" whether one 
or more) shall cause such operation (hereinafter called "non-consent 
operation") to be conducted by Operator at their cost and risk; provided, 
however, that if such operation is not commenced within one hundred eighty 
(180) days after the date of its proposal and thereafter continued with 
reasonable diligence, it may not be conducted without again being proposed to 
all Parties.

    8.16 All costs and risks of a non-consent operation will be borne and 
shared by the Participating Parties proportionately to their interests stated 
in Exhibit "A" hereof, or proportionately to their interests in the operation 
which is to be conducted, if different from their interests stated in Exhibit 
"A".

    8.17 Subject to the other provisions of this Agreement, including this 
Article VIII, all material and equipment placed in or on a well by the 
Participant(s), whether one or more, in a non-consent operation shall be 
owned by them, and, if the non-consent operation results in production, the 
Participant(s) therein shall own all operating rights therein and all 
production thereby obtained until such time as they shall have received 
currently an amount equal to 400% of the costs incurred by the Participating 
Parties in such operation which would have been paid by the 
Non-Participant(s) had it been a Participant out of (i) the proceeds of the 
sale of the share of such production to which such Non-participant(s) would 
have been entitled had it been a Participant, and (ii) 20% of the proceeds of 
the sale of the share of production to which such Non-participant(s) is 
entitled from production from other portions of the Lease, after deduction of 
the portion of operating expenses, royalty, other payments under Article VI 
hereof, and severance, production or other tax on such production which would 
have been paid by such Non-participant(s) had it been a Participant(s) 
("non-consent deductions"). Notwithstanding the foregoing, the Participants 
shall not be entitled to the aforesaid 20% of proceeds of the sale of the 
share of production on other portions of the Lease in the event that the well 
which was the occasion of the non-consent is not completed as a producer of 
oil or gas nor shall the Participants be entitled to the aforesaid 20% share 
of production from other portions of the Lease from any period of time after 
which production of oil and gas from the well which was the occasion of the 
non-consent has ceased to produce. In the case of the installation of a 
platform or equipment where all of the Parties do not participate therein, 
such platform or equipment shall be owned by the Participants until such time 
as Participants have received an amount equal to 400% of the cost incurred by 
the Participant(s) in designing, fabricating, transporting and installing 
such platform or equipment which would have been paid by the 
Non-participant(s) had it been a Participant(s). In the case of the 
installation of a non-consent platform, Non-participants shall have no 
ownership in such platform and shall be deemed to non-consent any proposals 
to drill a well from such platform until such time as Participants have 
recouped (i) 400% of the aforesaid portion of the cost of such platform, and 
(ii) 400% of the costs incurred by Participant(s) in drilling wells thereon 
which would have been paid by the Non-participant(s) had it been a 
Participant(s), out of the proceeds of the sale of the share of production 
from all wells drilled on such platform to which such Non-participant(s) 
would have been entitled had it been a Participant(s), less non-consent 
deductions. Non-participant(s) shall have the right at any time to become an 
owner of the platform or equipment by paying to Participant(s) in cash the 
then unrecouped balance in the recoupment account. It is further provided 
that the Participants shall not be entitled to the aforesaid 20% of proceeds 
from other portions of the Lease in connection with such non-consent platform 
and wells drilled thereon. In the case of the installation of equipment 
pursuant to the non-consent provisions of this Article VIII, the 
Participant(s) shall be entitled to recover 400% of the aforesaid cost of 
such equipment out of 20% of the proceeds of the sale of the share of 
production to which such Non-participant(s) is entitled from production from 
all wells which benefited from or are serviced by such equipment, less 
non-consent deductions.

         If a well is drilled hereunder as a non-consent operation, and such 
well is drilled from a facility other than a permanent platform, such as from 
a jackup rig or floating drilling vessel, and results in the discovery or 
extension 

                                  8
<PAGE>

of productive formations, 400% of the costs incurred by Participant(s) in the 
drilling of such a well which would have been paid by the Non-participant(s) 
had it been a Participant(s) shall be recouped out of the proceeds of the 
sale of the share of the production to which such Non-participant(s) would 
have been entitled had it been a Participant(s), less non-consent deductions, 
from said well and from the production from all other wells which develop the 
newly discovered or extended productive area completed from any platform 
subsequently located on the Lease, provided such a platform is located within 
three thousand feet (3,000') from the vertical projection of the bottomhole 
location of such non-consent well.

         The above mentioned proceeds shall be received and shared by the 
Participants in the proportions in which they participated in the non-consent 
operation.

    8.18 After the recovery of a Non-participant's recoupment account by 
Participants, such Non-participant shall own the interest in the well and all 
material and equipment therein and all subsequent production therefrom which 
it would have owned initially had it been a Participant. If the Participating 
Parties are unable to recover a Non-participant's recoupment account they 
shall continue to own the share of all material and equipment placed in or on 
said well by them which would have been owned by such Non-participant had it 
been a Participant and shall be entitled to the salvage value thereof, 
provided, however, that if the net salvage value is in excess of the 
unrecovered portion of such recoupment account the excess shall be credited 
to such Non-participant.

    8.19 Any Party or Parties owning an interest in the platform may use it 
free of charge for conducting drilling operations on the Property in 
accordance with this Agreement, but shall indemnify the other Parties against 
any loss, risk or expense resulting from such use.

    8.20 All operating, maintenance and repair expenses and liabilities 
attributable solely to the platform, and not to the drilling or producing of, 
or conducting of other operations in connection with, a particular well or 
wells, and all cost, risk and expense of salvaging the platform, and the net 
salvage thereof, will be shared on the basis of the then ownership of the 
platform. All such expenses and liabilities attributable to or arising out of 
the drilling or producing of, or the conducting of other operations in 
connection with, a particular well or wells will be charged to and borne by 
the then owners of such well or wells. The cost and expense of removing and 
returning the drilling rig initially placed on the platform will be shared on 
the basis of ownership of the platform at the time of its removal. The cost 
and expense of again placing a drilling rig on the platform, and of its 
removal, will be prorated on a well basis to the owners of wells on which it 
is used.

    8.21 At the request of any Party owning an interest in a platform, 
Operator shall furnish to the owners thereof the estimated net deficit or net 
value resulting from the salvage and removal of the platform, and any 
disagreement as to the amount of such deficit or value will be settled by a 
majority in interest of such owners. Within thirty (30) days after the fixing 
of such estimate, any Party owning an interest in a platform may propose to 
the other owners thereof that it be salvaged and removed from the lease, at 
the same time agreeing to convey its interest therein to any owner thereof 
desiring to retain the platform and to pay to or accept from such other 
owners such proposing Party's share of such estimated net deficit or net 
value, as the case may be. Any such other owner may, within thirty (30) days 
after receipt of such proposal, elect to retain the platform by giving notice 
thereof to the other owners, at the same time agreeing to accept its pro rata 
share of the interest of any Parties desiring salvage and removal and to make 
or accept payment for the estimated net value or net deficit attributable to 
such interest as hereinabove provided. The Parties will promptly thereafter 
make such payments and execute a conveyance, effective as of the date of the 
earliest notice given by a Party desiring to retain the platform, of the 
interest of the Parties desiring to salvage and abandon to the Parties 
desiring to retain such platform. From and after such effective date the 
Parties so conveying their interest will have no further rights, obligations 
or liabilities thereafter accruing with respect to such platform. If no Party 
desires to retain the platform, Operator shall proceed promptly to have same 
salvaged and removed at the cost of the owners thereof.

                            IX.  SURRENDER OR ABANDONMENT

                                  9
<PAGE>

    9.1  Unless otherwise provided for in this Agreement, the Parties shall 
not surrender or abandon any of the Property unless all Parties consent to 
the same in writing; provided, however, that such consent shall not 
unreasonably be withheld.

                       X.  SUNDRY RIGHTS AND DUTIES OF OPERATOR

    10.1 Operator shall conduct its activities under this agreement as a 
reasonable prudent operator, in a good and workmanlike manner, with due 
diligence and dispatch, in accordance with good oilfield practice, and in 
compliance with applicable law and regulation, but in no event shall it have 
any liability as Operator to the other Parties for losses sustained or 
liabilities incurred except such as may result from gross negligence or 
willful misconduct. Operator shall have the rights and discharge the duties 
set forth in this Article X, except as may be expressly provided otherwise 
elsewhere in this Agreement.

    10.2 Operator shall have control and supervision of all operations 
hereunder for the exploration and development for oil and gas production 
from, and for the abandonment and reclamation of, the Property. The approval 
of the drilling of any well hereunder shall include all necessary 
expenditures incurred by Operator in connection with drilling the well, 
including but not limited to testing and completing it for production.

    10.3 All wells drilled and all operations performed upon the Property by 
outside contractors shall be drilled or performed by qualified, responsible, 
independent contractors on a competitive contract basis to the extent 
competitive bids are available, or, if the wells are drilled under multi-well 
contracts, at the contract rates. Operator may, if approved by Non-operators, 
employ any of its own drilling equipment, tools or machinery in performing 
any operations under this Agreement, but such work shall be performed by 
Operator acting as an independent contractor under a written contract 
containing the same terms and conditions and at the same rate for using such 
equipment, tools and machinery as is customary, usual and prevailing in 
competitive contracts of independent contractors who are doing work of 
similar nature in the vicinity of the Lease.

    10.4 Operator shall have the right (subject to the provisions of the 
Accounting Procedure, Exhibit "B") to dispose of any salvaged material or 
equipment resulting from operations hereunder. The accounts of the Parties 
shall be credited with the proceeds thereof in proportion to their interest 
therein.

    10.5 Operator shall use reasonable diligence to see to the performance of 
all of the obligations of the Lease affecting the Property.  Operator shall 
endeavor to comply with all laws, rules and regulations governing the 
operations hereunder. Operations conducted hereunder shall be subject to 
applicable Executive Orders and applicable provisions of the Code of Federal 
Regulations. Operator shall endeavor to keep the Property free and clear of 
all liens in favor of third Parties resulting from construction or operations 
on or in respect of such Property. Operator shall undertake to see to the 
payment, on or before the date when they become due and payable, of all taxes 
assessed or levied against the Property, the respective interest of the 
Parties herein, or the production therefrom, including ad valorem taxes, 
production, severance and other taxes (other than income taxes) and 
governmental charges, except to the extent that any such taxes or charges may 
be paid or payable by the purchaser of any of the production.  Operator shall 
be authorized to make payments to the Fisherman's Contingency Fund, to the 
Offshore Oil Pollution Fund and to any other similar funds, and shall charge 
Non-operators for their share of such payments.

    10.6 The number of employees, the selection of such employees, the hours 
of labor and compensation for services to be paid any and all such employees 
shall be determined by the Operator and, as among the Parties hereto, such 
employees shall be the employees of Operator.

    10.7 Operator shall keep accurate books, accounts, and records of 
operations, which shall be available at reasonable times to each Party or its 
authorized representatives.

    10.8 Operator shall make all required reports to governmental authorities 
that it has the duty to make as Operator. Operator shall give timely written 
notice to the Parties of all litigation and hearings which affect the Lease 
or operations hereunder.

              mud logs (if any);

         e)   upon written request received by Operator prior to the 
              commencement of drilling, samples of cuttings and cores marked as 
              to depth to be packaged and shipped at the expense of the 
              requesting Party;

         f)   copies of any well tests, bottomhole pressure surveys, gas and

              operations.

The cost of gathering and furnishing information not ordinarily furnished to all
Parties shall be charged to the Party(s) that requests such information.

                       XI.  ACCESS AND RIGHTS OF NON-OPERATORS

    11.1 Each of the Non-operators hereto, for so long as such Non-operator 
has a Participating Interest, at its sole risk and expense shall have access 
at all reasonable times to the Property, including access to the rig floor, 
to inspect and observe any and all operations thereon. Each of the 
Non-operators, for so long as such Non-operator has a Participating Interest 
and upon reasonable notice, shall also have access at all reasonable times 
during normal office hours to any and all information pertaining to the 
operation, exploration, and development of the Property and the production 
secured therefrom, including Operator's books, records and vouchers relating 
thereto in the office in which such books, records and vouchers are kept.  
Operator shall, upon request, furnish any Party entitled thereto with copies 
of any and all drilling contracts, drilling reports, electric well survey 
logs, well logs, test data, tank tables, daily gauge and run tickets, and 
reports of production and stock on hand on the first day of each calendar 
month.  Operator shall also, upon request, make available to any Party 
entitled thereto samples of any and all cores, cuttings or fluids taken from 
or encountered in any wells drilled on the Property.

           XII.  ASSIGNMENT OF INTEREST AND PREFERENTIAL RIGHT TO PURCHASE

    12.1 For the purposes of this Agreement "Affiliate" shall mean when used 
in relation to the Parties hereto any corporation, partnership, joint venture 
or other entity other than a Party hereto that shall be directly or 
indirectly under the common control of, controlled by, or which controls, 
that Party.

    12.2 Except as provided in Paragraphs 12.3 and 12.4 below and subject to 
the provisions of Paragraph 12.5 below, no Party shall assign or transfer all 
or any part of its interest in the Property or this Agreement, or any of its 
rights and interests hereunder.

                                  11
<PAGE>

    12.3 Subject to the provisions of Paragraph 12.5 below, any Party may 
convey, assign or transfer all or any part of its interest in this Agreement 
and the Property to an Affiliate or to a successor by reason of merger, 
consolidation or reorganization or sale of substantially all of such Party's 
assets.

    12.4 If any Party receives from a person or entity, other than an 
Affiliate or successor as provided for in Paragraph 12.3 above, a bona fide 
offer to purchase or otherwise acquire all or any part of the offeree's 
interest in the Property, which the offeree is willing to accept, the offeree 
shall furnish in writing to the other Parties the complete terms of the 
offer; provided, however, if any part of the consideration offered is other 
than cash, in submitting such offer to the other Parties the offeree shall 
place a reasonable cash value on such non-cash part of the consideration and 
support such cash value with appropriate information and data upon which it 
is based. Each other Party shall have the right (in the proportion that its 
Participating Interest bears to the total Participating Interest of the 
Parties hereto other than the Participating Interest of the offeree Party, or 
in such other proportions as the Parties other than the offeree Party shall 
agree) for a period of 30 days after receipt of the offer to elect in writing 
to purchase or otherwise acquire the same interest upon the same terms and 
conditions as the proposed offer, but with the right to pay the entire 
consideration in cash; provided however, if a majority in interest of the 
other Parties do not agree that cash value of the non-cash part of the offer 
is reasonable, and the offeree and the other Parties are unable to agree 
within ten (10) days after the latest date on which any of the other Parties 
receive the offer (the "Receipt Date"), then both the offeree and the other 
Parties shall select a resident partner of one of the so-called "Big Eight" 
accounting firms (if such Parties are unable to agree on such a person within 
thirteen (13) days after Receipt Date, each side shall immediately designate 
such a partner and the two partners so designated shall within fifteen (15) 
days from Receipt Date select such a partner who shall act solely as 
hereinafter provided) furnish him with information, data and reasons 
supporting their respective cash values, and such partner, on or before 
twenty (20) days from Receipt Date, shall determine the reasonable cash value 
of the non-cash part of the consideration, which determination shall be 
final, unappealable, binding on all Parties and enforceable in a court of 
law, and shall be used in establishing the price at which the offeree may 
elect to reject the offer entirely and, if not, at which the other Parties 
shall elect to acquire or not acquire the interest offered. If the offer is 
not accepted by the other Parties, the offeree Party may sell or otherwise 
dispose of the interest described in the offer at the price and upon the 
terms and conditions of the proposed offer, provided (i) the provisions of 
Paragraph 12.5 below are satisfied, and (ii) that the sale or other 
disposition is effectuated within 120 days after the other Parties' right of 
election has expired. After the 120 day period has expired, the provisions of 
this Paragraph 12.4 shall again apply to the proposed offer for another 30 
day period, if that offer is still effective. The failure of the other 
Parties to exercise their rights to acquire an interest under this Paragraph 
12.4 shall not be deemed to be a waiver of their rights under this Paragraph 
12.4 with respect to subsequent offers.

         The preferential right to purchase and the procedures for 
implementing it set forth in this Paragraph 12.4 shall apply to all sales or 
other dispositions of all or any portion of a Party's interest in all or any 
portion of the Property, regardless of whether other interests or assets of 
the offeree Party also are included in such sale or other disposition. If the 
offeree Party is disposing of all or any portion of its interest in all or 
any portion of the Property together with other interests or assets held by 
the offeree Party, in its notice of offer to the other Parties, the offeree 
Party shall state the offered consideration for the interest in the Property, 
as it is set forth in the offer, including offeree's determination of a 
reasonable cash value for any non-cash part of the consideration, and if it 
is not set forth in the offer separately from the consideration offered for 
the other interests or assets of the offeree Party that are the subject of 
the offer, the offer shall state the reasonable cash value of the offered 
price or consideration relating to the interest in the Property. If the 
offeree and the other Parties cannot agree as to the reasonable cash value of 
the offered price or consideration relating to the interest in the Property, 
such reasonable cash value and the rights of the Parties thereunder shall be 
established as between the offeree and the other Parties following the same 
procedures set out in this Paragraph 12.4 for a determination of the 
reasonable cash value of the non-cash part of the consideration therein 
involved, however, the price so stated for the interest in the Property shall 
not exceed the fair market value of the same. The other Parties may elect, in 
the manner provided above in this Paragraph 12.4, to accept the offer as to 
only the interest in the Property but shall have no right as to the other 
interests and assets described in the notice.

    12.5 Any transfer, sale, assignment or other disposition of all or any 
part of the Property which is allowed under Paragraphs 12.3 or 12.4 hereof 
shall be subject to the following additional conditions: (a) any sale, 
transfer, assignment or other disposition shall be made only to a financially 
responsible Party or Parties; (b) all outstanding 

                                  12
<PAGE>

obligations and liabilities of the transferring Party under this Agreement 
due and owing as of the date of said transfer must be paid; (c) the 
transferee shall execute and deliver to the other Parties an agreement 
whereby it assumes and agrees to keep, observe and perform all of the terms, 
covenants and conditions of this Agreement and the Declaration to be kept, 
observed and performed on the part of the transferor, including without 
limitation a ratification and adoption by such transferee of the restrictions 
upon transfer and encumbrance contained in Article 2 of the Declaration and 
Article XII hereof and the lien and security interest granted under Section 
2.5 of the Declaration and Paragraph 21.1 hereof, (d) any sale, transfer, 
assignment or other disposition shall be subject to obtaining the approval of 
all required governmental authorities, and (e) if the original interest of 
any Party is at any time transferred to four (4) or more transferees, 
Operator may, at its discretion, require such transferees to appoint a single 
trustee with full authority to receive notices and payments, approve 
expenditures, and pay the share of costs which are chargeable against such 
transferees.

    12.6 No Party may execute a Mortgage affecting any part of its interest 
under this Agreement or the Property (other than the lien and security 
interest granted under Paragraph 21.1 hereof and Section 2.5 of the 
Declaration) unless the following conditions are first satisfied:

    (a)  The Mortgage and the rights of the Lender thereunder shall be made
         expressly subject to this Agreement and the Declaration as amended by 
         the Agreement to Coordinate Operating Agreements and the Agreement 
         Designating Acting Operator, executed among the Parties in connection 
         herewith, and as further amended from time to time, (as so amended, the
         "Documents") and the rights of the Parties hereunder and thereunder and
         the Mortgage shall contain a provision which binds the adjudicatee at a
         foreclosure sale arising out of the Mortgage or the transferee in a 
         deed in lieu of such foreclosure to (i) assume and agree to keep, 
         observe and perform all of the terms, covenants and conditions of the 
         Documents to be kept, observed and performed on the part of the 
         Mortgagor, including without limitation a ratification and adoption of 
         the restrictions on transfer and encumbrance contained in Article 2 of 
         the Declaration and Article XII hereof and the lien and security 
         interest granted under Section 2.5 of the Declaration and Paragraph 
         21.1 hereof, (ii) pay, within thirty (30) days of the date on which the
         said adjudicatee or transferee succeeds to any interest of the 
         Mortgagor in this Agreement or the Property all amounts owed by the
         Mortgagor under this Agreement which remain unpaid as of the date that 
         the said adjudicatee or transferee succeeds to any interest of the 
         Mortgagor in this Agreement or the Property, (iii) execute an agreement
         whereby such adjudicatee or transferee evidences its assumption 
         provided for under (i) above and agreement provided for under (iv)

         Agreement or the Property an agreement by the transferee thereto to 
         assume and agree to keep, observe and perform all of the terms, 
         covenants and conditions of the Documents to be kept, observed and 
         performed on the part of the Mortgagor, including without limitation a 
         ratification and adoption by such transferee of the restrictions on

         Article XII hereof and the lien and security interest granted under 
         Section 2.5 of the Declaration and Paragraph 21.1 hereof.

    (b)  The Lender shall agree in writing at the time the Mortgage is granted 
         that if the Lender is the adjudicatee at a foreclosure sale arising out
         of the Mortgage or the transferee in a deed in lieu of such 
         foreclosure, such Lender shall: (i) assume and agree to keep, observe 
         and perform all of the terms, covenants and conditions of the Documents
         to be kept, observed and performed on the part of the Mortgagor, 
         including without limitation a ratification and adoption of the

         conditions of the Documents to be kept, observed and performed on the

         the Declaration and Paragraph 21.1 hereof.

                 XIII.  RELATIONSHIP OF THE PARTIES AND TAX ELECTIONS

    13.1 This Agreement is not intended and shall not be construed to create 
a partnership within the meaning of the federal common law nor under the 
applicable laws of any state nor under the laws of any state in which any 
Party hereto is incorporated, organized or conducting business. The Parties 
expressly agree that no Party hereto shall be responsible for the obligations 
of any other Party, each Party being severally responsible only for its 
obligations arising hereunder and liable only for its allocated share of the 
costs and expenses incurred hereunder. It is not the purpose or intention of 
this Agreement to create, and this Agreement should never be construed as 
creating, a relationship whereby any of the Parties shall be held liable for 
acts, either of omission or commission, of any other Party hereto.

    13.2 The Parties agree to make an election under Internal Revenue Code 
section 761(a) out of the provisions of subchapter K of the Internal Revenue 
Code of 1986. Further, the Parties agree to take no action in contravention 
of this election including but not limited to entering into any agreement, 
contract, undertaking or any other act which would jeopardize the ability to 
make such election. The Parties also agree that, to the extent permissible 
under applicable law, their relationship shall be treated for state income 
tax purposes in the same manner as it is for federal income tax purposes.

                                 XIV.  FORCE MAJEURE

    14.1 In the event of any Party hereto being rendered unable, wholly or in 
part, by force majeure applying to its operations, to carry out its 
obligations under this Agreement (other than to make payments of amounts due 
hereunder), it is agreed that upon such Party's giving detailed written 
notice within a reasonable time of such force majeure to all Parties in 
interest, then the obligations of such Party so far as they are affected by 
such force majeure shall be suspended during the continuance of any inability 
so caused and such cause shall, so far as possible, be remedied with all 
reasonable dispatch. The term "force majeure" as employed herein shall mean 
acts of God, strikes, lockouts, or other industrial disturbances, acts of the 
public enemy, wars, blockades, insurrections, riots, epidemics, landslides, 
lightning, earthquakes, fires, storms, floods, washouts, arrests, and 
restraints of rulers and peoples, including unusual difficulty in obtaining 
pipe or other material or other unusual difficulty in carrying out operations 
hereunder because of government edict or regulations, civil disturbances, 
explosions, breakage or accident to machinery or lines of pipe, and any other 
cause whether of the kind herein enumerated or otherwise not within the 
control of the Party claiming suspension, all of which by the exercise of due 
diligence such Party is unable to foresee or overcome; however, the 
settlement of strikes or lockouts shall be entirely within the discretion of 
the Party having the difficulty, and the above requirement that any force 
majeure shall be remedied with the exercise of due diligence shall not 
require the settlement of strikes or lockouts by acceding to the demands of 
the opposing party when such course is inadvisable in the discretion of the 
Party having the difficulty.

                             XV.  INSURANCE AND LIABILITY

    15.1 Operator shall at all times while operations are conducted by it for 
the Joint Account on the Property carry, pay for and charge to the Joint 
Account such insurance in such amounts and covering such risks as Operator 
deems appropriate, as follows:

    (a)  WORKER'S COMPENSATION:

         Such insurance shall be in full compliance with the law in the state 
         where the work is to take place and shall contain a voluntary 
         compensation endorsement and a waiver of subrogation as to 
         Non-operators. Where applicable, coverage shall also be provided to 
         comply with the:

               wages, maintenance and cure.

         (ii)  A claim "in rem" will be treated as a claim "in personam".

         (iii) A waiver of subrogation as to Non-operators.

    It is agreed that the Operator, subject to the laws in the state or 
    jurisdiction where the work is to take place, may elect to self-insure all 
    or any portion of the Worker's Compensation and Employer's Liability 
    exposures arising out of operations conducted hereunder, provided all 
    Non-operators consent in writing to such election.

    (c)  All vessels owned or chartered by Operator shall be adequately covered 
         by Hull and Protection and Indemnity Insurance.

    (d)  No insurance other than as specified above shall be provided by the
         Operator.

    (e)  The premiums for all insurance policies obtained under this article 
         shall be charged to the Joint Account of the Parties hereto in 
         accordance with Exhibit "B" and Operator, upon written request, shall 
         furnish evidence certifying such insurance.

    (f)  The Operator shall require contractors and subcontractors performing 
         work for the Joint Account to provide such insurance as deemed 
         reasonable by the Operator in relation to the work to be performed by 
         said contractors or subcontractors.

    (g)  Upon request, certificates of insurance evidencing the insurance 
         obtained by Operator hereunder shall be furnished to each Non-operator 
         and each Non-operator shall furnish to Operator certificates of 
         insurance evidencing the insurance obtained by Non-operator in 
         compliance with the provisions hereof.

    (h)  Unless otherwise agreed in writing, Operator and Non-operator shall
         separately carry their own policies of the following insurance:

         (i)   Control of Well Insurance in the minimum amount of $50,000,000 
               for the total loss.

         (ii)  Where applicable, Blanket Charterers' Legal Liability and Cargo 
               Legal Liability with a limit of liability of $500,000.

         (iii) Umbrella Liability Insurance in the amount of $25,000,000 excess
               of all primary limits.

         (iv)  Above insurance coverages, including but not limited to any and 
               all deductibles, self-insured retentions or primary layers, shall
               contain waivers of subrogation as to the Parties hereto.

    15.2 Notwithstanding anything contained in this Agreement to the 
contrary, each Party shall be responsible for all costs, liabilities, claims, 
damages and liens for property or personal injury, as well as pollution cost 
and damage, 

                                  15
<PAGE>

arising out of any operation on the Property in proportion to its 
Participating Interest, except as to such costs, liabilities, claims, damages 
and liens caused by the gross negligence or willful misconduct of any Party 
to this Agreement, in which case such Party shall be liable therefor.

    15.3 Operator shall at any time requested furnish any Non-operator with 
full information concerning the kind, character and amounts of insurance 
carried. Operator shall promptly notify Non-operators of any loss, damage or 
claim not covered by insurance carried by the Operator for the benefit of the 
Joint Account or individual Non-operators.

    15.4 Operator shall not be liable for loss, damage or destruction to any
property of Non-operators in connection with operations hereunder for the Joint
Account on or in respect of the Property, except those arising out of willful
misconduct or gross negligence of Operator.

    15.5 Each Party, in proportion to its Participating Interest shall be 
liable for any losses and expenses that exceed the amount collectable under 
the insurance carried by Operator for the Joint Account (as set forth in 
Paragraph 15.1) on account of personal injury or death to any person in 
connection with operations hereunder; provided however, all Parties shall 
share in the loss to the extent of their interest unless such loss is caused 
by the willful misconduct or gross negligence of one of the Parties hereto; 
then in such event the loss shall be borne entirely by that Party.

    15.6 Subject to the other provisions of this Agreement, each Party, to 
the extent of its Participating Interest, shall indemnify and save harmless 
the other Parties hereto for claims and losses that exceed the amounts 
collectible under the insurance carried by Operator for the Joint Account (as 
set forth in Paragraph 15.1), regardless of the negligent acts or omissions 
of Operator. Nothing contained in this Paragraph 15.6 shall be deemed to 
release the Operator from its obligation under Article X hereof.

    15.7 Liability for (1) damages to property of "third persons" (as used in 
this paragraph, the term "third persons" shall not include the employees, 
agents or representatives of Operator or any Non-operator), (2) fines, 
penalties, damages, losses, etc., arising out of claims, either civil or 
criminal, public or private, relating to actual or alleged pollution of 
water, air, or the environment, or (3) injury to or death of third persons 
arising from operations on or in respect of the Property including the 
expenses incurred in defending claims or actions asserting liabilities of 
this character, shall be borne by the Parties in proportion to said Parties' 
respective Participating Interests, except that when such damage is caused by 
the gross negligence or willful misconduct of Operator, then Operator shall 
be responsible for such liability. In the event such damage is caused by one 
or more of the Non-operators, then in that event, the liability for such 
damage shall be borne by the Non-operator or Non-operators responsible, 
except when a Non-operator is expressly authorized to act for the Joint 
Account, then any such damage except that caused by the gross negligence or 
willful misconduct of such Non-operator shall be borne by the Parties in 
proportion to their respective Participating Interests.

    15.8 In the event of a judgment against Operator as the result of a 
personal injury, death and/or property loss or damage case arising out of 
operations hereunder and brought by a party or parties other than a Party to 
this Agreement, which judgment includes a finding of gross negligence on the 
part of Operator, the Court's finding of gross negligence shall not be 
binding for purposes of determining whether or not any Non-operator is 
obligated hereunder to share the burdens of any such judgment unless the 
gross negligence was found to be attributable to an act or omission of an 
officer or director of Operator. In the event the gross negligence was found 
to be attributable to an act or omission of an employee of Operator other 
than an officer or director, the facts and circumstances giving rise to such 
judgment shall be submitted to a board of arbitration, as hereinafter 
provided, for an independent determination, in light of applicable law and 
generally accepted standards in the offshore oil and gas producing industry, 
of the degree of negligence exhibited by the Operator; provided, however, 
that the previous finding of gross negligence on the part of Operator shall 
not be admitted in evidence in such arbitration proceeding. For purposes of 
this Paragraph 15.8, Operator shall, as soon as practicable following the 
judgment containing the gross negligence finding, give notice of submission 
to the Non-operators, which notice shall name one arbitrator. The 
Non-operators shall, within thirty (30) days after the date such notice is 
given, agree among themselves to the appointment of one arbitrator and give 
notice of such appointment to the Operator, failing in which the arbitrator 
shall be appointed by the then senior United States District 

                                  16
<PAGE>

Judge for the Eastern District of Louisiana. The two arbitrators so selected 
shall select a third arbitrator or umpire within twenty (20) days after the 
giving of notice of the appointment of the second arbitrator. Should the two 
arbitrators selected by Operator and the Non-operators fail so to agree upon 
a third arbitrator or umpire, either Operator or the Non-operators may upon 
ten (10) days' written notice to the other apply to the then senior United 
States District Judge for the Eastern District of Louisiana for the 
appointment of such third arbitrator or umpire. The arbitrators so appointed 
shall promptly hear and determine (after due notice of hearing and giving the 
Parties a reasonable opportunity to be heard) the negligence issue submitted, 
and shall render their decision which shall be final and nonappealable and 
absolutely binding and conclusive upon Operator and Non-operators. The 
expenses of the arbitrator selected by Operator shall be paid by Operator and 
the expenses of the arbitrator selected by the Non-operators shall be paid by 
the Non-operators. The expenses of the third arbitrator shall be borne 
one-half by Operator and one-half by the Non-operators. Operator's attorney 
fees and expenses attributable to the arbitration shall be paid by Operator 
and Non-operators' attorney fees and expenses attributable to the arbitration 
shall be paid by the Non-operators.

    15.9  All references in this Article XV to the extent of or in proportion 
to Participating Interest shall refer to those cases in which all Parties 
participated in an operation, but in the case of an operation in which fewer 
than all of the Parties participated, the reference shall be to the 
Participating Parties and shall apply in proportion to such Parties' 
interests in such operation.

    15.10 Notwithstanding anything contained in this Agreement to the 
contrary, no Party, including the Operator, shall be responsible or liable 
for any consequential loss or damage of the other Parties hereto, included 
but not limited to, inability to produce oil or gas, loss of reserves, loss 
of production or loss of profits.

                             XVI.  CLAIMS AND LITIGATION

    16.1  All investigation, litigation and settlements in connection with 
the titles, claims and causes of action of every kind and joint rights and 
interests hereunder shall be carried on, conducted and defended for and on 
behalf of all Parties involved. Each Party shall notify the others of any 
process served upon it in any suit or claims hereunder. The Policy Committee 
shall decide whether the handling and defense of such suit or claim shall be 
handled by the attorneys of all Parties or by joint counsel selected by a 
majority in interest of the Parties. When such selection has not been made in 
time to permit preparation, filing, appearance or other representation in 
accordance with legal requirements, Operator is authorized to provide such 
legal services as in its discretion are necessary to preserve the rights of 
the Parties and shall charge the cost and expense of same to the Joint 
Account. If less than all Parties participate through their attorneys in such 
litigation, a reasonable charge for legal services provided by participating 
counsel shall be made to the Joint Account. If the attorneys of all Parties 
participate, no fee or expense for their services shall be charged to the 
Joint Account. The fee and expense of any joint counsel selected by the 
Policy Committee shall be charged to the Joint Account.

    16.2  All settlements of all claims and suits shall be subject to the 
approval and agreement of the Policy Committee, except that Operator may 
settle any claim under $100,000 without consulting Non-operators, provided 
the payment is in complete settlement. Operator agrees to keep Non-operators 
advised as to claims for which Non-operators may be partly responsible 
hereunder. The amount of settlement shall be charged to the Joint Account.

    16.3  All references in this Article XVI to charges to the "Joint 
Account" shall refer to those cases in which all Parties participated in an 
operation, but in the case of an operation in which fewer than all of the 
Parties participated, the reference shall be to the Participating Parties and 
shall apply in proportion to such Parties' interests in such operation.

                                   XVII.  DURATION

    17.1  This Agreement shall continue in full force and effect for as long 
as the Lease, or any extensions or renewals thereof, is continued in force as 
to any part of the Property, whether by production or otherwise, and 
thereafter until all Equipment has been salvaged and disposed of and final 
settlement and accounting had between the Parties, unless otherwise mutually 
agreed upon by all Parties hereto.

    19.1  The topical headings appearing at the top of each numbered 
paragraph have been inserted for convenience only and are to be given no 
force or effect whatever. The provisions of this Agreement shall control in 
the event of any conflict or inconsistency with the provisions of any Exhibit 
attached hereto.

                             XX.  SUCCESSORS AND ASSIGNS

    20.1  This Agreement shall be binding upon and inure to the benefit of 
the Parties hereto, their successors and permitted assigns, and the terms, 
conditions and provisions hereof shall constitute covenants running with the 
lands and leasehold estates covered hereby.

                                     XXI.  LIENS

    21.1  Each other Party hereby mortgages, pledges and hypothecates to 
Operator and the Acting Operator, and grants Operator and the Acting Operator 
a security interest, and Operator hereby mortgages, pledges and hypothecates 
to the other Parties and the Acting Operator and grants the other Parties and 
the Acting Operator a security interest, in any interest each Party now owns 
or may hereafter acquire in and to: (i) the Property, (ii) the Equipment, 
(iii) the Collateral, and any (iv) Hydrocarbons, as security for the payment 
and performance of all obligations, liabilities and indebtedness of each 
Party under this Agreement or under the Agreement Designating Acting 
Operator, now or hereafter arising, up to the Limit for each Party as 
hereinafter set forth (as to each Party, the "Secured Obligations"). The lien 
and security interest granted by each Party secures the Secured Obligations 
of such Party and the lien and security granted by the Operator also secures 
the obligations, liabilities and indebtedness of the Acting Operator up to 
the limit for the Operator as hereinafter set forth. Any person acquiring an 
interest in this Agreement and the Property, whether by assignment, merger, 
mortgage, operation of law, or otherwise, shall be deemed to have taken such 
interest subject to the liens and security interests granted by this 
Paragraph 21.1 as to all Secured Obligations attributable to such interest 
being acquired whether or not such Secured Obligations arose before or after 
such interest is acquired. The secured Parties hereunder shall be entitled to 
exercise the rights and remedies of a secured creditor under applicable 
Louisiana law, including but not limited to Chapter 9 of the Louisiana 
Commercial Laws, R.S. 10:9-101 ET SEQ. (the "Act"). The bringing of a suit 
and obtaining of judgment by a Party for Secured Obligations shall not be 
deemed an election of remedies or otherwise affect the lien rights or 
security interests and security for the payment thereof. This Paragraph 21.1 
shall constitute a security agreement under the Act. The lien and security 
interest herein granted shall be superior to and have priority over any 
Mortgage. The maximum amount of the Secured Obligations of each Party to be 
secured hereunder (the "Limit") is fixed as $65,910,000, with reference to 
Freeport, $28,250,000 with reference to IMC, and $18,840,000 with reference 
to Felmont. To perfect the lien and security interest herein provided, each 
Party hereto shall execute and acknowledge any financing statement or other 
instrument prepared or submitted by any Party hereto in connection therewith 
or at any time following execution thereof, and Operator and/or the Acting 
Operator are authorized to file this Agreement as a lien and mortgage in 
applicable real estate records and as a financing statement with the proper 
office under the Act.

                                  18
<PAGE>
         Each Party represents and warrants to the other Parties hereto and 
to the Acting Operator that the lien and security interest granted by such 
Party to the other Parties and to the Acting Operator shall be a first and 
prior lien and security interest, and each Party agrees to maintain the 
priority of said lien and security interest against all persons acquiring an 
interest in the Property by, through or under such Party.

         If any Party does not perform all of its Secured Obligations 
hereunder, and the failure to perform will subject such Party to foreclosure 
or execution proceedings, the defaulting Party waives any available right of 
redemption from and after the date of judgment, any required valuation or 
appraisement of the mortgaged or secured property prior to sale, any 
available right to stay execution or to require a marshalling of assets and 
any required bond in the event a receiver is appointed. In addition, to the 
extent permitted by applicable law, each Party hereby grants to the other 
Parties a power of sale as to any property that is subject to the lien and 
security interest granted hereunder, such power to be exercised in the manner 
provided by applicable law or otherwise in a commercially reasonable manner 
and upon reasonable notice. Each Party agrees that the other Parties shall be 
entitled to utilize the provisions of any applicable oil and gas lien law or 
other lien law to enforce the Secured Obligations of each Party hereunder.

    21.2  In the event any Non-operator should fail to pay its share of the 
charges, costs and expenses incurred under this Agreement within forty-five 
(45) days after actual receipt of a statement of same for any month, except 
as to amounts which are being disputed in good faith, such Non-operator shall 
be deemed delinquent. If after fifteen (15) days following actual receipt of 
notice of delinquency by a Non-Operator (or by an officer of the Non-operator 
if it is a corporation), Operator has not received payment, or the 
Non-operator has not made other arrangements for payment satisfactory to 
Operator, the delinquent Non-operator shall be deemed to be in default and 
Operator, without prejudice to other existing remedies, is authorized, at its 
election, to collect from the purchaser or purchasers of Hydrocarbons, the 
proceeds accruing to the working interest or interests in the Property of the 
delinquent Non-operator free and clear of all liens and encumbrances and of 
any burdens thereon to the extent provided in Paragraph 21.5, up to the 
amount owed by such Non-operator plus interest thereon at the rate specified 
in Paragraph 3.3, and each purchaser of oil and gas is authorized to rely 
upon Operator's statement as to the amount owed by such Non-operator.

    21.3  In the event of neglect or failure of any Non-operator promptly to 
pay its share of the costs and expenses of development and operation when 
due, and provided that the Operator has asserted its lien granted under 
Paragraph 21.1 and 21.2 to production proceeds, and the proceeds from the 
sale of oil and gas, if any, accruing to the delinquent Non-Operator's 
Participating Interest in the Property are being paid to the Operator by the 
purchaser or purchasers, the other Non-operators and Operator, within thirty 
(30) days after the rendition of statements therefor by Operator, shall, in 
proportion to their Participating Interests, contribute to the payment of 
such delinquent indebtedness and the Non-operators so contributing shall be 
entitled to the same lien rights as are granted in Paragraphs 21.1 and 21.2 
to Operator. Upon the payment by the delinquent or defaulting Non-operator to 
Operator of any amount or amounts on such delinquent indebtedness, or upon 
any recovery on behalf of the Parties under the lien conferred in Paragraph 
21.1, the amount or amounts so paid or recovered shall be distributed and 
paid by Operator to the other Non-operators and Operator proportionately in 
accordance with the contributions theretofore made by them.

    21.4  Any Party in default shall, until such time as such Party's 
payments are current, have no access to the maps, records, data, 
interpretations or other information obtained in connection with the 
operations under this Agreement after the default has occurred, shall not be 
represented in the Policy Committee and shall not be entitled to vote on any 
matter. Furthermore, such Party shall not be entitled to receive any notice 
of meetings or decisions of the Policy Committee.

    21.5  If any Party hereto should create any overriding royalty, 
production payment, or other burden against its working interest production 
and if any other Party or Parties shall become entitled to receive the 
working interest production otherwise belonging to another Party hereto 
pursuant to any provisions of this Agreement, the Party or Parties entitled 
to receive the working interest production of the other Party shall receive 
such production free and clear of such burdens against such production which 
may have been created, except as to such Party's or Parties' proportionate 
part of any overriding royalty interest, production payment or other burden 
that proportionately burdens the interests of all Parties hereto, and the 
Party or Parties creating such burdens shall save the other Party or Parties 
harmless with respect to the receipt of such working interest production.

                                  19

    21.6  The Non-operators have acquired their respective interests in the 
Lease and the Equipment from the Operator pursuant to that certain Assignment 
and Conveyance effective June 5, 1990 (the "Assignment and Conveyance") and 
that certain Bill of Sale effective June 5, 1990 (the "Bill of Sale"). 
Pursuant to the Assignment and Conveyance and the Bill of Sale, each 
Non-operator has agreed to indemnify and defend the Operator for certain 
obligations, liabilities and indemnities more particularly described therein, 
and the Operator has agreed to indemnify and defend the Non-operators for 
certain obligations, liabilities and indemnities more particularly described 
therein. As used herein, the term "Secured Obligations" of each of the 
respective Parties shall include without limitation the respective 
obligations, liabilities and indemnities owed by each of the Non-operators to 
the Operator, and owed by the Operator to the Non-operators, under the 
Assignment and Conveyance and the Bill of Sale.

                             XXII.  LAWS AND REGULATIONS

    22.1  All the terms and provisions of this Agreement are hereby expressly 
made subject to all federal and state laws and to all orders, rules and 
regulations of any duly constituted authority having jurisdiction in the 
premises, and no Party shall suffer a forfeiture or be liable in damages for 
failure to comply with any of the provisions of this Agreement if such 
compliance is prevented by or if such failure results from compliance with 
any such law, order, rule or regulation.

                                   XXIII.  DISPUTES

    23.1  In the event of disagreement between any of the Parties as to the 
intent and interpretation hereof, this Agreement shall be subject to and 
interpreted in accordance with the laws of the State of Louisiana and the 
laws of the United States.

                                 XXIV.  NO PARTITION

    24.1  Prior to the termination of this Agreement, a Party or its 
successors or assigns shall not resort to any action to partition the 
Property and, to such extent, each Party waives the benefits of all laws 
authorizing such action.

                                     XXV.  WAIVER

    25.1  The failure or omission by either Party to enforce any provision of 
this Agreement shall not be considered to be a waiver of that provision or of 
the default of another Party of its obligations under that provision or under 
any other provision of this Agreement.

                                 XXVI.  SEVERABILITY

    26.1  It is understood and agreed by the Parties that if any part, term 
or provision of this Agreement is held by a court of competent jurisdiction 
to be illegal or unenforceable or both, the Parties desire that the court of 
competent jurisdiction reform that part, term or provision in such a manner 
as to approximate the intent of the Parties as expressed in this Agreement, 
and the validity of the remaining portions or provisions shall not be 
affected.

                      XXVII.  DECLARATION OF OPERATING AGREEMENT

    27.1  The Parties hereto agree to execute the Declaration for the purpose 
of imparting notice to all persons of the rights and obligations of the

    4.03 RELATIONSHIP OF THE PARTIES.  It is not the purpose or intention of
this Agreement to create a partnership, tax partnership, mining partnership,
commercial partnership, or any other partnership relation between the Parties.
Each Party shall be responsible only for its obligations and liabilities as set
forth in this Agreement. Nothing contained in this Agreement shall be deemed to
constitute any Party the partner of any other Party, or except as otherwise
expressly provided, to constitute any Party the agent or legal representative of
any other Party, or to create any fiduciary relationship among them. No Party
shall have any authority to act for or to assume any obligation or

Parties shall own any and all sulphur produced from the Property in proportion
to their respective Participating Interests (as such Participating Interests may
be adjusted from tine to time under the provisions hereof) subject to the
payment of royalties payable to the lessor of the sulphur and salt mining rights
within the Property. Subject to the further provisions of this Section 4.05
regarding New Technology, the Parties also shall jointly own any and all Joint
Assets held or acquired pursuant to this Agreement in the same proportion as
their respective Participating Interests in the Property. Should any Party,
subsequent to the date of this Agreement, burden any of the Property with any
minimum or overriding royalties or other payments out of production, the same
shall be borne and paid entirely by the Party creating such burden out of that
Party's proportionate part of production from the Property.

    All New Technology shall be owned by the Operator, who shall be free to
deal with and use such New Technology in connection with any commercial or other
operations outside the Joint Operations and to license or otherwise grant
licenses in respect to such New Technology to parties other than Parties to this
Agreement ("NonParties") on such terms and conditions as it may deem fit;
provided, however, that any proceeds derived by the Operator from any such
licenses to Non-Parties shall be divided among the Parties in proportion to
their Participating Interests; and further provided that the Operator hereby
grants each of the Parties a worldwide, nonexclusive, royalty-free license and
right to use the New Technology at any project or venture in which any such
Party, either directly or indirectly through an affiliate or affiliates of said
Party, has an equity of at least sixteen and two-thirds percent (16 2/3%) for as
long as such project or venture remains in commercial operation and such Party

to the New Technology, and shall refrain from disclosing any such information
and data to any Non-Party, except to the extent required for compliance with
applicable laws and rules, regulations and orders of a governmental authority,
or as may be required by any such commercial project or venture in which any
such Party has said equity of at least sixteen and two-thirds percent. Any Party
entering into any such commercial project or venture shall secure from any
Non-Party involved in said commercial project or venture adequate
confidentiality agreements to protect the confidentiality of New Technology data
and information to the same extent as that to which such Party is obligated
hereunder.

                                 V.  POLICY COMMITTEE

    5.01 COMPOSITION.  The Parties establish a Policy Committee to be composed
of one representative designated by each Party.

    A representative designated pursuant to this Section 5.01 shall serve until
replaced by the Party that designated such representative. Each Party also may
designate one or more alternates for any representative designated by it. An
alternate shall exercise voting rights only in the event of a representative's
absence. Each representative may bring to Policy Committee meetings such
advisors as the representative deems necessary or desirable; however, such
advisors shall have no right to vote on matters before the Policy Committee.

    Each Party promptly shall advise the other Parties in writing as to the
names and addresses of its representative and alternate representative who shall
have the authority to represent and bind the advising Party with respect to any
matter to be acted upon by the Policy Committee. A Party's representative or
alternate representative may be changed from time to time upon written notice to
the other Parties.

    5.02 MEETINGS.  The Operator will provide to the Non-operators a proposed
Work Plan and Budget not later than September 15 of each year. The Non-operators
shall respond by October 15 of each year with the regular meeting to be held
between October 15 and November 1 of each year; provided, however, that the
first regular meeting shall be held not later than ninety (90) days after the
Effective Date and shall be for the purpose of review and approval of the Work
Plan and Budget for the period commencing on the Effective Date and ending on
December 31, 1988. Special meetings shall be called by the Operator as and when
the Operator should deem necessary. Any of the Parties to this 

                                  6
<PAGE>

Agreement shall have the right to call a special meeting provided that no 
such special meeting shall be called sooner than three months after the last 
such special meeting. During the fifth month of each Budget Year the Operator 
shall call an advisory meeting for the sole purpose of informing the Policy 
Committee of the progress of Joint Operations for the current Budget Year to 
date. The Parties and Operator shall attend all regular, special and advisory 
meetings of the Policy Committee. All meetings shall be held at operator's 
offices, unless all Parties agree to another location. Written notice of the 
time and place of each regular, special and advisory meeting, shall be 
submitted by the Operator to the Parties, not less than 15 days before any 
such meeting, unless such requirement of notice is waived in writing by the 
Parties. The holding of any advisory meeting may be waived provided all 
Parties consent to such waiver.

    Operator shall act as chairman at all Policy Committee meetings. Each Party
shall bear its own cost of attendance.  If Operator deems it necessary for any
personnel who are assigned duties in connection with the conduct of Joint
Operations to attend any meeting, the cost incurred therefor shall be charged to
the Joint Account.

    5.03 POLICY COMMITTEE POWERS.  The Policy Committee shall approve all Work
Plans and Budgets and supplements thereto and revisions thereof, settlement of
claims and suits in accordance with the provisions of Section 13.02, and shall
have the right and authority to wind up the activities of the Joint Operations
following termination of this Agreement as provided in Section 20.02. Any
contract proposed to be entered into by operator pursuant to an approved Work
Plan and Budget for a capital expenditure in excess of $1,000,000 shall be on a
competitive bid basis; provided, however, that in no event shall any contract be
entered into for a capital expenditure in excess of $5,000,000 without Policy
Committee approval of the amount of such expenditure.

    5.04 POLICY COMMITTEE ACTION.  Only those Parties owning a Participating
Interest of ten percent (10%) or more may vote on matters before the Policy
Committee. Policy Committee approval of any matter requiring Policy Committee
approval hereunder, shall require the vote of Operator and the vote of at least
one other Party entitled to vote; provided, however, that if only one Party
other than Operator should be entitled to vote then Policy Committee approval of
any such matter shall require only the vote of Operator.

    With respect to any matter submitted by Operator for Policy Committee
approval (other than approval of a Feasibility Study), should Operator be unable
to obtain the vote of at least one other Party entitled to vote, then in such
event all Parties entitled to vote shall continue good faith negotiations to
resolve outstanding differences. In the event the Policy Committee is unable to
secure approval of a proposed Work Plan and Budget within 60 days, the Operator
shall submit an alternate proposed Work Plan and Budget. In any event, the
Operator shall incur for the Joint Account such expenditures as it reasonably
determines to be necessary for the continued maintenance of the lease covering
the Property and shall be permitted to operate the Mine at a level which
preserves the value of the Joint Assets. No formal Policy Committee approval
shall be necessary for such expenditures or for such operations.

    In lieu of deciding any matter at any meeting, the Policy Committee (a) may
act by instrument(s) in writing signed by the representative of each
Participating Interest Owner, which instrument(s) (in one or more counterparts)
shall be conclusively deemed to be the act of the Policy Committee, or (b) by
telephone communication provided that such action is unanimous and is confirmed
in writing by each Party or each Party's representative.

                                    VI.  OPERATOR

    6.01 FREEPORT AS OPERATOR.  Freeport is designated as Operator for all

<PAGE>

                  VII.  WORK PLANS AND BUDGETS; FEASIBILITY STUDIES

    7.01 WORK PLANS AND BUDGETS; EXPLORATION BUDGET LIMITATION; BUDGET
OVERRUNS.  Operator shall have the sole right to propose work Plans and Budgets
and Budget Supplements. The Work Plan and Budget for the period commencing on
the Effective Date and ending on December 31, 1988, shall be prepared by the
Operator and submitted to the Policy Committee not later than 30 days prior to
the first regular meeting. Operator shall prepare and submit to the Policy
Committee a Work Plan and Budget for each Budget Year, not less than thirty (30)
days prior to the regular meeting called to review and approve such Work Plan
and Budget, all as more particularly provided in the Operating Provisions. No
Exploration Work Plan and Budget submitted by Operator for a Budget Year shall
provide for costs and expenses for such Budget Year to exceed a total of
$1,500,000.  Operator shall not be deemed to have exceeded any approved Work
Plan and budget provided the total of actual costs and expenses incurred by the
implementation of such Work Plan and Budget does not exceed by more than
twenty-five percent the total costs and expenses authorized for such Work Plan
and Budget; provided, however, if such actual costs and expenses will exceed
such percentage of authorized costs and expenses, Operator shall be required to
submit a revised Work Plan and Budget in respect of such excess costs and
expenses for Policy Committee approval. Operator shall have absolute discretion
in deciding which costs and expenses shall or shall not be incurred for purposes
of keeping costs and expenses of an approved Work Plan and Budget within the
limits authorized therefor. The Policy Committee shall consider all Work Plans
and Budgets submitted by Operator pursuant to the Operating Provisions and,
except as otherwise provided in Section 5.04 above, shall take action thereon in
accordance with Section 7.03 below.

    7.02 SUPPLEMENTAL AND REVISED WORK PLANS AND BUDGETS.  From time to time,
Operator, pursuant to the Operating Provisions or pursuant to Section 7.01
above, may propose supplemental or revised Work Plans and Budgets to the Policy
Committee which shall consider and take action thereon in accordance with
Section 7.03 below. Any such supplement or revision shall be prepared as
provided in the operating Provisions and shall be submitted to the Policy
Committee as far in advance of implementing the supplemental or revised Work
Plan and Budget as is reasonably possible.

    7.03 REVIEW AND APPROVAL OF PROPOSED WORK PLANS AND BUDGETS.  The Policy
Committee shall consult in a good faith effort either to approve or adopt each
proposed Work Plan and Budget (or revision thereof or supplement thereto) as
submitted, or to formulate an alternative Work Plan and Budget acceptable to the
Parties. Actions on all Work Plans and Budgets shall be taken as provided for in
Section 5.04. Once approved as provided in Section 5.04 and, subject to the
rights of the Parties to elect not to participate or to limit their
participation pursuant to Article VIII, the annual Work Plan and Budget, any
approved supplement thereto or any approved revision thereof, shall be binding
on the Parties and shall be carried out by Operator.

    7.04 FEASIBILITY STUDIES AND FIRST DEVELOPMENT OPERATIONS WORK PLAN AND
         BUDGET

    A.   PROPOSAL TO CONDUCT FEASIBILITY STUDY AND APPROVAL OF WORK PLAN AND
BUDGET FOR FEASIBILITY STUDY.  At such times as the operator is of the good
faith and reasonable opinion that an economically viable mining operation may be
possible on the Property, the Operator will propose that a Feasibility Study be
conducted on the Property. Such proposal shall be made in writing to the Policy
Committee, shall reference the Data upon which the operator has based its
opinion and shall include a Work Plan and Budget for the proposed Feasibility
Study. The Operator shall at the same time call a special meeting of the Policy
Committee pursuant to Section 5.02 above. The Work Plan and Budget for such
Feasibility Study shall be deemed to be a revised or supplemental Work Plan and
Budget for Exploration Operations pursuant to the Operating Provisions for the
Budget Year during which the Feasibility Study is proposed to be commenced. The
Policy Committee shall have 30 days in which to approve or disapprove of the
Work Plan and Budget proposed for the Feasibility Study. Upon approval by the
Policy Committee of the Work Plan and Budget for the Feasibility Study in
accordance with Section 7.03 and this Section 7.04A, Operator shall prepare or
cause to be prepared a Feasibility Study in accordance with the approved Work
Plan and Budget therefor.

                                  8
<PAGE>

    B.   APPROVAL OF FEASIBILITY STUDY AND COMMENCEMENT OF DEVELOPMENT
OPERATIONS.  Upon completion of the Feasibility Study, operator shall submit the
Feasibility Study to the Policy Committee which, notwithstanding anything to the
contrary expressed or implied in Section 5.04 or Section 7.03 above, shall have
90 days in which to approve or disapprove of the Feasibility Study. If the
Feasibility Study is approved, the Operator shall prepare and submit in
accordance with the Operating Provisions, the first Development Operations Work
Plan and Budget to commence no later than the beginning of the next ensuing
Budget Year. Once approved by the Policy Committee as provided in Section 7.03
and this Section 7.04B and subject to the rights of the Parties to elect not to
participate or to limit their participation pursuant to Section 8.01, the first
Development Operations Work Plan and Budget shall be binding on the Parties and
shall be carried out by Operator.

                VIII.  CONDUCT OF OPERATIONS BY LESS THAN ALL PARTIES

    8.01 EXPLORATION PROGRAM.  During the Exploration Program, Party may elect
to terminate participation in the Joint Operations by giving written notice to
Operator of its termination at any regular or special meeting of the Policy
Committee. If a Party makes such election, such Party shall relinquish and
assign all of its interest in and to the Joint Assets and the Agreement to the
then remaining Participating Interest Owners in accordance with Section 9.01 and
without any recompense whatsoever from such remaining owners for such
relinquishment and assignment.

    8.02 DEVELOPMENT OPERATIONS; FREEPORT'S DEFERRAL RIGHT.  Each Participating
Interest Owner shall have a period of 30 days after the Approval Date of the
Feasibility Study to elect by notice to Operator prior to the end of such period
(a) to participate in the Development and Production Programs at such owner's
then Participating Interest, or (b) to participate in the Development and
Production Programs at a Participating Interest lower than such owner's then
Participating Interest (provided such lower Participating Interest is not less
than ten percent), or (c) to not participate in the Development and Production
Programs. Should a Participating Interest Owner elect (b), such owner's
Participating Interest shall be adjusted downward in accordance with Section
9.02.  Should a Participating Interest Owner elect (c), such owner shall sell
all of its interest in and to the Joint Assets and this Agreement to the then
remaining Participating Interest Owners in accordance with Section 9.03.

    If the Operator votes to disapprove a Feasibility Study but all other
Participating Interest Owners entitled to vote should vote to approve such
Feasibility Study, the Operator shall have the right, exercisable within 10 days
after Operator's vote of disapproval, to declare a Development Moratorium. As
used in this Agreement, the term "Development Moratorium" shall mean a period of
up to 3 years after the date of such declaration during which the operator may
defer commencement of Development Operations on the Property, subject to
Operator reviewing its position on deferral with the Policy Committee at each
annual regular meeting of such committee held during such period, subject to
maintenance of the Joint Assets during such period, and subject to the condition
that in no event shall the Development Moratorium endure beyond the commencement
of the eighth year of the sulphur lease covering the Property. At any time
during the Development Moratorium, Operator shall have the right to submit to
the Policy Committee a first Work Plan and Budget for Development Operations,
and, upon submission of such Work Plan and Budget, the operator shall be deemed
to have approved the Feasibility Study and the Development Moratorium shall be
deemed to have terminated as of such time. Such Work Plan and Budget shall then
be submitted to the Policy Committee for approval. For purposes of this Section
8.02, the word "Year" shall mean a period of 365 consecutive days.

    Within the aforementioned 10-day period during which Operator may declare a
Development Moratorium, Operator may, in lieu of making such declaration, elect,
by notice to each of the Parties prior to the end of such period, any of the
following courses of action or any compatible combination thereof:

    (i)  resignation as Operator;

    (ii) participation in the Development and Production Programs at Operator's
         then Participating Interest;

                                  9
<PAGE>

    (iii)     participation in the Development and Production Programs at a
              Participating Interest lower than the operator's then
              Participating Interest (provided such lower Participating
              Interest is not less than ten percent) in accordance with and
              subject to the provisions of Section 9.02;

    (iv)      no participation in the Development Program and mandatory sale of 
              all of its interest in and to the Joint Assets and this Agreement 
              to the then remaining Participating Interest Owners in accordance 
              with Section 9.03.

    (The courses of action outlined in items (i) - (iv) above, are hereinafter
collectively referred to as "Operator Development Options").

    Operator shall also have the right to elect any or all of the Operator
Development Options by notice to each of the Parties at any time during the
Development Moratorium or at such time as the Development Moratorium shall have
terminated without Operator having submitted to the Policy Committee a first
Work Plan and Budget for Development Operations.

                        IX.  CHANGE IN PARTICIPATING INTERESTS

    9.01 READJUSTMENT OF INTERESTS WITH RESPECT TO THE EXPLORATION PROGRAM. 
Any Participating Interest Owner electing during the Exploration Program
pursuant to Section 8.01 to cease further participation in the Joint Operations,
shall, upon the date such election becomes effective, relinquish and assign all
of its interest in and to the Joint Assets and this Agreement free and clear of
all liens and encumbrances to the then remaining Participating Interest Owners
in proportion to the ratio of their then Participating Interests as of the time
immediately prior to such relinquishment and assignment. For example, assume
that immediately prior to the relinquishment and assignment the Participating
Interest of Operator is 50% and the Participating Interests of Participating
Interest Owners A, B, and C is 16-2/3% each. Assume further that during the
Exploration Program owner C elects to cease further participation in the Joint
Operations. In such case the portion of the 16-2/3% share owned by owner C
(hereinafter referred to as the "Relinquished Interest") to be allocated to each
of Operator, Owner A and Owner B would be calculated as follows:

EXAMPLE A:
         Participating
         Interest
         Immediately         Proportional Share       Adjusted
         Prior to            of Relinquished          Participating
Party    Relinquishment      Interest                 Interest   
- -----    --------------      ------------------       -------------

Operator 50.00%    +         .6000  X  16.67%         =    60.00%
Owner A  16.66%    +         .1999  X  16.67%         =    19.99%
Owner B  16.67%    +         .2000  X  16.67%         =    20.00%

    For purposes of any readjustment of the percentage interests or burdens of
the Parties hereunder, whether as the result of allocation of a Relinquished
Interest as aforesaid, or pursuant to any other provision of this agreement,
fractions of a percentage shall be rounded off to two decimal places, and, if as
a result of such rounding off the sum of the readjusted percentage interests or
burdens, as the case may be, (i) should total less than one hundred percent,
Operator's interest or burden, as the case may be, shall be increased to the
extent necessary for such sum to equal one hundred percent; or (ii) should such
sum total more than one hundred percent, Operator's interest or burden, as the
case may be, shall be decreased to the extent necessary for such sum to equal
one hundred percent. In Example A above the sum of the adjusted Participating
Interests is 99.99%. In such case, operator's adjusted Participating Interest of
60.00% would be increased to 60.01% in order for the sum of the adjusted
Participating Interests to total one hundred percent.

                                  10
<PAGE>

    9.02 READJUSTMENT OF INTERESTS WITH RESPECT TO THE DEVELOPMENT AND
PRODUCTION PROGRAMS.  Any Participating Interest owner electing pursuant to
Section 8.02 to participate in the Development and Production Programs at a
Participating Interest lower than such owner's Participating Interest prior to
such election, shall in its notice to Operator of such election declare the
percentage constituting the lower Participating Interest at which such owner
desires to participate (which percentage shall in no event be less than 10
percent), and, within 30 days after the date such notice is given, the
percentage interest representing the difference between such owner's
Participating Interest immediately prior to and immediately after such election
(hereinafter referred to as the "Partial Relinquished Interest") shall be
relinquished and assigned free and clear of all liens and encumbrances to the
then remaining Participating Interest Owners as hereinafter in this Section 9.02
provided. The aforesaid relinquishment and assignment of the Partial
Relinquished Interest shall be made to the then Remaining Participating Interest
Owners in proportion to the ratio of their then Participating Interests as of
the time immediately prior to such election.

    For example, assume that immediately prior to the election the
Participating Interest of Operator is 50% and the Participating Interests of
Participating Interest Owners A, B, and C is 16-2/3% each. Assume further that
Owner C elects to participate in the Development Program at a Participating
Interest of 10% rather than its then current Participating Interest of 16-2/3%.
For such case the portion of the 6-2/3% Partial Relinquished Interest to be
allocated to each of Operator, Owner A and Owner B would be calculated as
follows:

EXAMPLE B:

         Participating
         Interest
         Immediately         Proportional Share       Adjusted
         Prior to            of Relinquished          Participating
Party    Relinquishment      Interest                 Interest       
- -----    --------------      -------------------      -------------

Operator 50.00%    +         .6000  X  6.66%          =   54.00%
Owner A  16.66%    +         .1999  X  6.66%          =   17.99%
Owner B  16.66%    +         .1999  X  6.66%          =   17.99%
Owner C  16.66%    +                 NONE             =   10.00%

    9.03 MANDATORY SALE OF PARTICIPATING INTEREST.  Should a Party elect
pursuant to Section 8.02 to not participate in the Development and Production
Programs, such Party shall within 30 days after giving appropriate notice of
such election, sell, transfer and assign, all of its interest in and to the
Joint Assets and this Agreement free and clear of all liens and encumbrances to
the then remaining Participating Interest Owners for a total purchase price
equal to the sum of (i) the total amount paid by such Party to lessor to acquire
such Party's interest in the sulphur lease covering the Property, plus (ii) the
sum of all expenditures made by such Party for Joint Operations on the Property.
The portion of such purchase price to be paid by each of the then remaining
Participating Interest Owners, and the portion of such Party's Participating
Interest to be sold, transferred and assigned to each such remaining owner shall
be allocated proportionately using the proportionate allocation methodology
employed in Sections 9.01 and 9.02 above (with necessary changes in points and
details).

                              X.  LIENS AND ENCUMBRANCES

    10.01     As security for the payment and performance of all obligations,
liabilities and indebtedness of each Party hereto arising under or pursuant to
this Agreement, up to the aggregate sum at any one time outstanding of
$134,159,000 as to the operator, $57,500,000 as to IMC, and $38,341,000 as to
Felmont (the "Obligations"), each Party shall grant to the other Parties hereto
a mortgage lien and pledge affecting such granting Party's interest in (i) the
sulphur lease covering the Property, (ii) all corporeal movables placed on said
lease, and (iii) all minerals produced from said lease together with all
proceeds thereof. At the time of the execution and delivery of this Agreement,
each party shall execute and deliver to the other Parties hereto the instruments
necessary to create the aforementioned mortgage lien and 

                                  11
<PAGE>

pledge, conforming to the form and substance of that collateral mortgage and 
pledge, collateral mortgage note and collateral pledge agreement attached 
hereto as Attachment 1. Any Party may furnish substitute security which must 
be acceptable to all other Parties hereto. If such offered substitute 
security is not acceptable to all other Parties hereto, and such offering 
Party is unable because of prior corporate contractual commitments to furnish 
the mortgage, note and pledge referred to above, then the other Parties shall 
have the right to purchase the non-performing Party's interest in the sulphur 
lease covering the Property at a price equal to that Party's share of the bid 
price and first annual rental of such lease. The right of the other Parties 
to purchase the interest in such lease from the nonperforming Party shall be 
in the proportions as their respective interests in such lease bear to the 
total of their interests in such lease, or in such other proportions as they 
may agree.

    10.02     Subject to Section 10.01 above, no Party shall encumber or cause
or permit a lien to be placed upon such Party's interest in or under this
Agreement or upon any of the Joint Assets without the prior written consent of
the other Parties. Consent shall not be withheld if the purpose of the Party
proposing the encumbrance is to obtain funds to carry out or maintain its
position under this Agreement. If the other Parties do not give the Party
proposing the encumbrance notice of their objections to the proposed encumbrance
and request for consent within thirty (30) days following receipt of notice, the
other Parties shall be deemed to have consented to it. No encumbrance made
pursuant to this Article X shall impair or reduce the rights of any other Party
in any way and all security interests created by such encumbrance shall be
subordinate to all rights of the other Parties under this Agreement.

                                    XI.  INSURANCE

    11.01     Operator shall at all times while operations are conducted by it
for the Joint Account on the Property and the Mine, carry, pay for and charge to
the Joint Account such insurance in such amounts and covering such risks as
Operator deems appropriate, as follows:

              (a)  WORKER'S COMPENSATION:

                   Such insurance shall be in full compliance with the law in 
                   the state where the work is to take place and shall contain a
                   voluntary compensation endorsement and a waiver of 
                   subrogation as to Non-Operators. Where applicable, coverage 
                   shall also be provided to comply with the:

                   (i)   U. S. Longshoremen's and Harbor Worker's Compensation 
                         Act, and the

                   (ii)  Outer Continental Shelf Lands Act.

              (b)  EMPLOYER'S LIABILITY:

                   Such insurance shall have a limit of liability of $1,000,000 
                   per accident and shall be endorsed, where applicable, to 
                   provide:

                   (i)   Maritime (Amendment to Coverage B), to include
                         transportation, wages, maintenance and cure.

                   (ii)  A claim "in rem" will be treated as a claim "in 
                         personam".

                   (iii) A waiver of subrogation as to Non-Operators.

              (c)  No insurance other than as specified above shall be provided 
                   by the Operator.  Operator may elect to self-insure as to the
                   insurance specified above provided all Non-Operators consent 
                   in writing to such election.

                                  12
<PAGE>

              (d)   Operator shall require contractors and subcontractors 
                    performing work for the Joint Account to provide such 
                    insurance as deemed reasonable by the Operator in relation 
                    to the work to be performed by said contractors or 
                    subcontractors.

              (e)   All vessels owned or chartered by Operator shall be 
                    adequately covered by Hull and Protection and Indemnity 
                    Insurance.

              (f)   Upon request, certificates of insurance evidencing the 
                    insurance obtained by operator hereunder shall be furnished 
                    to each Non-Operator and each Non-Operator shall furnish to 
                    Operator certificates of insurance evidencing the insurance 
                    obtained by Non-Operator in compliance with the provisions 
                    hereof.

    11.02     Unless otherwise agreed in writing, Operator and Non-Operator
shall separately carry their own policies of the following insurance:

              (i)   Control of Well Insurance in the minimum amount of 
                    $25,000,000 for the total loss.

              (ii)  Where applicable, Blanket Charterers' Legal Liability and 
                    Cargo Legal Liability with a limit of liability of $500,000.

              (iii) Umbrella Liability Insurance in the amount of $25,000,000
                    excess of all primary limits.

              (iv)  Above insurance coverages, including but not limited to any 
                    and all deductibles, self-insured retentions or primary 
                    layers, shall contain waivers of subrogation as to the 
                    Parties hereto.

    11.03     Notwithstanding anything contained in this Agreement to the
contrary, those Parties participating in any operation on the Property or the
Mine shall be responsible for all costs, liabilities, claims, damages and liens
for loss or damage to property or personal injury or death, as well as pollution
cost and damage, arising out of such operation in the proportion that such
Parties participated in the operation including reclamation and abandonment
costs that gave rise to such costs, liabilities, claims, damages and liens
unless caused by the gross negligence or willful misconduct of any Party to this
agreement, in which case such Party shall be liable therefor; provided, however,
such participating Parties shall not be responsible or liable for any
consequential loss or damage of the other Parties hereto, including but not
limited to, inability to produce sulphur, loss of reserves, loss of production
or loss of profits.

    11.04     Operator shall at any time requested furnish any Non-Operator
with full information concerning the kind, character and amounts of insurance
carried. Operator shall promptly notify Non-Operators of loss, damage or claim
not covered by insurance carried by the Operator for the benefit of the Joint
Account or individual Non-Operators.

    11.05     Operator shall not be liable for loss, damage or destruction to
any property of Non-Operators in connection with operations hereunder for the
Joint Account on the Property or the Mine, except those arising out of willful
misconduct or gross negligence of Operator.

    11.06     Each Party, in proportion to its Participating Interest, or in
the case of Joint Operations in which fewer than all the Parties participate, in
proportion to such Party's Participating Interest shall be liable for any losses
and expenses that exceed the amount collectable under the insurance carried by
operator for the Joint Account (as set forth in Paragraph 11.01) on account of
personal injury or death to any person in connection with Joint Operations
hereunder; provided however, all Parties shall share in the loss to the extent
of their respective Participating Interests unless such loss is caused by the
gross negligence or willful misconduct of one of the Parties hereto; then in
such event the loss shall be borne entirely by that Party.

                                  13
<PAGE>

    11.07     Subject to the other provisions of this Agreement, each Party
shall indemnify and save harmless the other Parties hereto for claims and losses
that exceed the amounts collectible under the insurance carried by Operator for
the Joint Account (as set forth in Section 11-01), regardless of the negligent
acts or omissions of Operator. Nothing contained in this Section 11.06 shall be
deemed to release the Operator from its obligations under this Agreement.

    11.08     Liability for (1) damages to property of "third persons" (as used
in this paragraph, the term "third persons" shall not include the employees,
agents or representative of operator or any Non-Operator), (2) fines, penalties,
damages, losses, etc., arising out of claims, either civil or criminal, public
or private, relating to actual or alleged pollution of water, air, or the
environment, or (3) injury to or death of third persons arising from operations
on the Property or the Mine including the expenses incurred in defending claims
or actions asserting liabilities of this character, shall be borne by the
Parties in proportion to said Parties, respective Participating Interests, or in
the case of Joint operations in which fewer than all the Parties participate, in
proportion to such Party's Participating Interest except that when such damage
is caused by the gross negligence or willful misconduct of Operator, then
operator shall be responsible for such liability. In the event such damage is
caused by one or more of the Non-Operators, then in that event, the liability
for such damage shall be borne by the Non-Operator or Non-Operators responsible,
except when a Non-Operator is expressly authorized to act for the Joint Account,
then any such damage except that caused by the gross negligence or willful
misconduct of such Non-Operator shall be borne by the Parties in proportion to
their respective Participating Interests.

    11.09     In the event of a judgment against operator as the result of a
personal injury, death and/or property loss or damage case arising out of
operations hereunder and brought by a Non-Party or Non-Parties, which judgment
includes a finding of gross negligence on the part of Operator, the court's
finding of gross negligence shall not be binding for purposes of determining
whether or not any Non-Operator is obligated hereunder to share the burdens of
any such judgment unless the gross negligence was found to be attributable to an
act or omission of an officer or director of Operator. In the event the gross
negligence was found to be attributable to an act or omission of an employee of
Operator other than an officer or director, the facts and circumstances giving
rise to such judgment shall be submitted to a board of arbitration, as
hereinafter provided, for an independent determination, in light of applicable
law and generally accepted standards in the offshore mineral producing industry,
of the degree of negligence exhibited by the Operator; provided, however, that
the previous finding of gross negligence on the part of Operator shall not be
admitted in evidence in such arbitration proceeding. For purposes of this
Section 11.09, operator shall, as soon as practicable following the judgment
containing the gross negligence finding, give notice of submission to the
Non-Operators, which notice shall name one arbitrator. The Non-Operators shall,
within thirty (30) days after the date such notice is given, agree among
themselves to the appointment of one arbitrator and give notice of such
appointment to the Operator, failing in which the arbitrator shall be appointed
by the then senior United States District Judge for the Eastern District of
Louisiana. The two arbitrators so selected shall select a third arbitrator or
umpire within twenty (20) days after the giving of notice of the appointment of
the second arbitrator. Should the two arbitrators selected by Operator and the
Non-Operators fail so to agree upon a third arbitrator or umpire, either
Operator or the Non-Operators may upon ten (10) days' written notice to the
other apply to the then senior United States District Judge for the Eastern
District of Louisiana for the appointment of such third arbitrator or umpire.
The arbitrators so appointed shall promptly hear and determine (after due notice
of hearing and giving the parties a reasonable opportunity to be heard) the
negligence issue submitted, and shall render their decision which shall be final
and nonappealable and absolutely binding and conclusive upon Operator and
Non-Operators. The expenses of the arbitrator selected by Operator shall be paid
by Operator and the expenses of the arbitrator selected by the Non-Operators
shall be paid by the Non-Operators. The expenses of the third arbitrator shall
be borne one-half by Operator and one-half by the Non-Operators. Operator's
attorney fees and expenses attributable to the arbitration shall be paid by
Operator and Non-Operators' attorney fees and expenses attributable to the
arbitration shall be paid by the Non-Operators.

                                 XII.  TAX ELECTIONS

    The Parties agree to make an election under Internal Revenue Code section
761(a) out of the provisions of subchapter K of the Internal Revenue Code of
1986. Further, the Parties agree to, take no action in contravention of this

                                  14
<PAGE>

election including but not limited to entering into any agreement, contract,
undertaking or any other act which would jeopardize the ability to make such
election. The Parties also agree that, to the extent permissible under
applicable law, their relationship shall be treated for state income tax
purposes in the same manner as it is for federal income tax purposes.

                             XIII.  CLAIMS AND LITIGATION

    13.01     All investigation, litigation and settlements in connection with
the titles, claims and causes of action of every kind and joint rights and
interests hereunder shall be carried on, conducted and defended for and on
behalf of all Parties involved. Each Party shall notify the others of any
process served upon it in any suit or claims hereunder. The Parties shall decide
by a majority in interest whether the handling and defense of such suit or claim
shall be handled by the attorneys of all Parties or by joint counsel selected by
a majority in interest of the Parties. When such selection has not been made in
time to permit preparation, filing, appearance or other representation in
accordance with legal requirements, Operator is authorized to provide such legal
services as in its discretion are necessary to preserve the rights of the
Parties and shall charge the cost and expense of same to the Joint Account. If
less than all Parties participate through their attorneys in such litigation, a
reasonable charge for legal services provided by participating counsel shall be
made to the Joint Account. If the attorneys of all Parties participate, no fee
or expense for their services shall be charged to the Joint Account.  The fee
and expense of any joint counsel selected by a majority in interest shall be
charged to the Joint Account.

    13.02     All settlements of all claims and suits shall be subject to the
approval and agreement of the Policy Committee, except that operator may settle
any claim under $100,000 without consulting or obtaining the approval of the
Policy Committee, provided the payment is in complete settlement. Operator
agrees to keep Non-Operators advised as to claims for which Non-Operators may be
partly responsible hereunder. The amount of settlement shall be charged to the
Joint Account.

    13.03     All references in this Article XIII to charges to the "Joint
Account" shall refer to those cases in which all Parties participated in such
operation, but in the case of an operation in which fewer than all of the
Parties participated, the reference shall be to the participating Parties and
shall apply in proportion to such Parties' interests in such operation.

                                  XIV.  COMPETITION

    With respect to any property rights outside of the Property, each Party
shall have the free and unrestricted right, independently or in combination with
others, to engage in and receive the full benefits of any and all business
endeavors of any sort whatsoever, including but not limited to the acquisition
of properties, interests, or rights in and the exploration for production and
sale of sulphur whether or not competitive with the endeavors contemplated
herein. Except as provided in this Article XIV or in Article XV below, it is
expressly agreed that a Party shall not have any fiduciary obligation or other
duty of whatsoever character to the other Parties that would prevent it from
engaging in or enjoying the benefits of such competing endeavors or would
require it to consult with or allow such other Parties to participate therein.

                           XV.  NO PARTITION OR OTHER USES

    Prior to the termination of this Agreement, a Party or its successors or
assigns shall not (a) resort to any action to partition the Property and, to
such extent, each Party waives the benefits of all laws authorizing such action;
or (b) utilize or attempt to utilize all of any portion of the Property for uses
or purposes other than those set forth in Article II of this Agreement without
the prior written consent of the other Parties.

                                  15
<PAGE>


                            XVI.  SURRENDER OR ABANDONMENT

    The Parties shall not surrender or abandon any of the Property unless all
Parties consent to the same in writing; provided, however, that such consent
shall not unreasonably be withheld.


                 XVII.  ASSIGNMENT AND PREFERENTIAL RIGHT TO PURCHASE

    17.01     ASSIGNMENT.  Except as provided in Section 17.02 below, and
except as to the right of a Party to receive in kind and separately dispose of
such Party's share of sulphur produced at the Mine as provided in Article XVIII
hereof, no Party shall assign or transfer all or any part of its interest in the
Property, the Joint Assets, this Agreement or any of its rights and interests
hereunder to any party other than a Party or an Affiliate unless it shall have
first offered to make such assignment to the other Parties pursuant to Section
17.03 below.


    17.02     EXEMPT TRANSFERS.  Any Party may convey, assign or transfer all
or any part of its interest in this Agreement the Property, and/or the Joint
Assets, to an Affiliate, or to a successor by reason of sale of substantially
all of a Party's assets, merger, consolidation or reorganization; provided,
however, that the Affiliate, or successor shall in writing assume and agree to
carry out all, or a corresponding portion, of the transferring Party's
obligations arising under this Agreement.


    17.03     PREFERENTIAL RIGHT TO PURCHASE.

    A.        PROCEDURE.  If any Party receives from a person or entity, 
other than those described in Section 17.02 above, a bona fide offer to 
purchase or otherwise acquire all or any part of the offeree's interest in 
this Agreement, the Property, and/or the Joint Assets which the offeree is 
willing to accept, the offeree shall furnish in writing to the other Parties 
the complete terms of the offer; provided, however, if any part of the 
consideration offered is other than cash, in submitting such offer to the 
other Parties the offeree shall place a reasonable cash value on such 
non-cash part of the consideration and support such cash value with 
appropriate information and data upon which it is based. The other Parties 
shall have the right for a period of 30 days after receipt of the offer to 
elect in writing to purchase or otherwise acquire the same interest upon the 
same terms and conditions as the proposed offer, but with the right to pay 
the entire consideration in cash; provided, however, if a majority in 
interest of the other Parties do not agree that cash value of the non-cash 
part of the offer is reasonable, and the offeree and the other Parties are 
unable to agree within ten (10) days after the latest date on which any of 
the other Parties receive the offer (the "Receipt Date") , then both the 
offeree and the other Parties shall select a resident partner of one of the 
"Big Eight" accounting firms (if such parties are unable to agree on such a 
person within thirteen (13) days after Receipt Date, each side shall 
immediately designate such a partner and the two partners so designated shall 
within fifteen (15) days from Receipt Date select such a partner who shall 
act solely as hereinafter provided) furnish him with information, data and 
reasons supporting their respective cash values, and such partner, on or 
before twenty (20) days from Receipt Date, shall determine the reasonable 
cash value of the non-cash part of the consideration, which determination 
shall be final, unappealable, binding on all Parties and enforceable in a 
court of law, and shall be used in establishing the price at which the 
offeree may elect to reject the offer entirely and, if not, at which the 
other Parties shall elect to acquire or not acquire the interest offered. If 
the offer is not accepted by the other Parties, the offeree Party may sell or 
otherwise dispose of the interest described in the offer at the price and 
upon the terms and conditions of the proposed offer, provided (i) that all 
other Parties consent in writing to such sale or disposition (which consent 
shall not be unreasonably withheld), (ii) that the sale or other disposition 
is effectuated within 120 days after the other Party's right of election has 
expired, and (iii) that the transferee agrees in writing to assume all of the 
transferring Party's obligations and liabilities under this Agreement. After 
the 120 day period has expired, the provisions of this Section 17.03 shall 
again apply to the proposed offer for another 30 day period, if that offer is 
still effective. The failure of the other Parties to exercise their rights to 
acquire an interest under this Section 17.03 shall not be deemed to be a 
waiver of their rights under this Section 17.03 with respect to subsequent 
offers.


    B.        APPLICATION GENERALLY.  The preferential right to purchase and 
the procedures for implementing it set forth in Section 17.03A shall apply to 
all sales or other dispositions of all or any portion of a Party's interest 
in all or 

                                  16
<PAGE>

any portion of this Agreement, the Property, and/or the Joint Assets,
regardless of whether other interests or assets of the offeree Party also are
being sold or otherwise subjected to disposition. If the offeree Party is
disposing of all or any portion of its interest in all or any portion of this
Agreement, the Property, and/or the Joint Assets, together with other interests
or assets held by the offeree Party, in its notice of offer to the other
Parties, the offeree Party shall state the offered consideration for the
interest in this Agreement, the Property, and/or the Joint Assets, as it is set
forth in the offer, including offeree's determination of a reasonable cash value
for any non-cash part of the consideration, and if it is not set forth in the
offer separately from the consideration offered for the other interests or
assets of the offeree Party that are the subject of the offer, the offer shall
state the reasonable cash value of the offered price or consideration relating
to the interest in this Agreement, the Property, and/or the Joint Assets. If the
offeree and the other Parties cannot agree as to the reasonable cash value of
the offered price or consideration relating to the interest in this Agreement,
the Property, and/or the Joint Assets, such reasonable cash value and the rights
of the Parties thereunder shall be established as between the offeree and the
other Parties following the same procedures set out in this Section 17.03A for a
determination of the reasonable cash value of the non-cash part of the
consideration therein involved, however, the price so stated for the interest in
this Agreement, the Property, and/or the Joint Assets, shall not exceed the fair
market value of the same. The other Parties may elect, in the manner provided
above in this Section 17.03, to accept the offer as to only the interest in this
Agreement, the Property, and/or the Joint Assets, but shall have no right as to
the other interests and assets described in the notice.

    C.        APPLICATION TO OPERATOR'S INTEREST.  In the event Operator 
should sell or otherwise dispose of a portion of its interest in all or any 
portion of this Agreement, the Property, and/or the Joint Assets, but retain 
its rights as Operator, Operator shall continue to be obligated to act as a 
reasonable and prudent Operator in the conduct of operations and the 
performance of its obligations hereunder. The provisions of this Article XVII 
shall not be construed to allow the sale or transfer of this operatorship of 
the Property separate and apart from its interest in the Property.

    17.04     TRANSFERRING PARTY NOT RELEASED FROM AGREEMENT.  A transferring
Party shall not be relieved of any of its obligations or liabilities (including
but not limited to reclamation obligations owing to a landowner or governmental
entity) under this Agreement existing at the time of transfer, unless the other
Parties consent thereto in writing and the transferee agrees in writing to
assume all of the transferring Party's obligations and liabilities under this
Agreement.

    17.05     EVIDENCE OF CHANGE OF OWNERSHIP.  No change in ownership of any
interest in all or any portion of this Agreement, the Property, and/or the Joint
Assets shall be binding upon the other Parties until a certified copy of all
instruments executed and delivered in connection with the transfer or assignment
shall have been delivered to the other Parties.

    17.06     AGENT OF ASSIGNEE CO-OWNERS.  If, at any time the interest of any
original Party to this Agreement is divided among and owned by two (2) or more
co-owners, Operator, at its discretion, may require such co-owners to appoint a
single trustee or agent with full authority to receive notices, approve
expenditures, receive billings for and approve and pay such assignees' share of
the Joint Expenses, and to deal generally with, and with power to bind, the
assignees of such interest within the scope of operations embraced by this
Agreement.

                          XVIII.  DISPOSITION OF PRODUCTION

    18.01     PARTICIPATING INTEREST OWNERS.  Pursuant to the terms of the
Operating Provisions and this Article XVIII, each Participating Interest Owner
shall receive in kind and separately dispose of a portion of the sulphur
produced at the Mine equal to its Participating Interest as of the time of
commencement of Steaming Operations, exclusive of any sulphur which the lessor
of the sulphur lease covering the Property should elect to take in kind and
exclusive of any sulphur that may be unavoidably lost.

    Any extra expenditures (including but not limited to expenditures incurred
in the construction, operation and maintenance of any and all facilities that
may be necessary to receive, store and dispose of a Party's share of production)

                                  17
<PAGE>

in excess of the cost of constructing, maintaining and operating the Joint
Assets incurred by the reason of taking in kind or separate disposition by such
Party of its proportionate share of the sulphur so produced shall be borne by
that Party. It is the intent of the Parties that any sulphur mine constructed
hereunder will include such facilities beyond the wellhead as are necessary to
transport the sulphur production to a permanent short-term storage facility or
other point from which separate delivery may be taken and to provide or
construct such storage or other facility and its ancillary load-out facilities
as may be necessary.

    18.02     ELECTION TO NOT RECEIVE AND NOT PAY.  Each Party other than the
Operator shall have the right, exercisable by notice to Operator within 15 days
after its receipt from Operator of the Production Work Plan and Budget for the
Budget Year covered by such Work Plan and Budget, to elect (i) not to receive
such Party's share of sulphur produced at the Mine during such Budget Year, and
(ii) not to pay such Party's share of Joint Expenses for such Budget Year;
provided, however, that such Party shall not have such right with respect to any
Budget Year if the Work Plan and Budget for such Budget Year received from the
operator indicates that the estimated total unit cost (less depreciation) per
ton of sulphur to be produced at the Mine during such Budget Year exceeds the
Tampa Posting as of the time such Work Plan and Budget is received by such Party
from Operator; nor shall such party have such right if at the time of such
election there remains to be produced less than thirty percent of the largest
total of proven, recoverable reserves underlying the Property (such total being
the same as reported to the Securities and Exchange Commission by Operator in
its Form 10K). The term "Tampa Posting" as used herein shall mean the arithmetic
average of the high and low contract price per ton of Frasch Sulfur FOB Tampa
published in GREEN MARKETS FERTILIZER MARKET INTELLIGENCE WEEKLY, under the
heading Green Markets Price-Scan U.S. Domestic Spot Quotes, for Contracts. If
such Party makes such election, such Party shall forfeit its right to receive
its share of sulphur produced at the Mine during such Budget Year and shall have
no obligation to pay its share of Joint Expenses for such Budget Year except as
hereinafter in this Section 18.02 provided. Such Party's share of Joint Expenses
for such Budget Year shall be allocated proportionately to the other Parties
using the proportionate allocation methodology employed in Sections 9.01 and
9.02 above (with necessary changes in points and details). If at the end of the
Budget Year for which such Party made the election provided for by this Section
18.02, the Operator determines that the actual total unit cost (less
depreciation) per ton to produce sulphur at the Mine during such year exceeds
the time weighted per ton average price for such year based on prices reported
to the Minerals Management Service for payment of royalties for such year
(hereinafter referred to as the "Average Price") . then such Party shall pay to
the Joint Account within 15 days after receipt of operator's invoice therefor,
an amount calculated by (i) subtracting the "Average Price" per ton for such
year from (ii) the actual total unit cost (less depreciation) per ton of sulphur
produced at the Mine during such year, and (iii) multiplying the remainder by
(iv) the number of tons representing such Party's proportionate share of sulphur
produced at the Mine during such year.

                                     IX.  DEFAULT

    In the event of any default by any Party or Operator in the performance of
any of its obligations under this Agreement, other than payment of dollar
amounts due Operator for the Joint Account, the non-defaulting Party or Parties
shall give to the defaulting Party written notice of the default. If the default
is not cured within 60 days after receipt of the notice, or if the defaulting
Party has not within that time begun action to cure the same and does not
thereafter diligently prosecute such action to completion, the non-defaulting
Party or Parties may bring an action in a court of competent jurisdiction for
any and all damages of whatsoever nature incurred by it as a result of the
default. If the defaulting Party disagrees that a default occurred, it shall so
advise the nondefaulting Party or Parties in writing within 30 days after
receipt of the notice of default. The Parties shall attempt to resolve the
dispute by mutual agreement, but if they are unable to do so within 60 days
after the notice of default, the issue of default shall be submitted to a court
of competent jurisdiction. The defaulting Party shall not be deemed to be in
default unless it is so adjudged by such court and until all appeals from said
decision have either been exhausted or waived. If the defaulting Party is found
to be in default by the court, it shall have 60 days after the date on which all
appeals have been exhausted or waived in which to either cure the default, begin
action to diligently cure the same, or pay damages awarded by such court to the
non-defaulting Party or Parties.

                                  18
<PAGE>

    If at any time during the Exploration and Development Programs, a Party
which is a Participating Interest Owner at such time should default in making
payments due Operator for the Joint Account, operator, in addition to any other
rights and remedies it may have in law or at equity or pursuant to this
Agreement, shall have the right, exercisable at any time after the expiration of
the ninetieth (90th) day following such defaulting Party's receipt of Operator's
written notice of such default, to give such defaulting Party a notice of
forfeiture, upon receipt of which notice such defaulting Party shall, within 15
days of its receipt thereof, relinquish and assign all of such Party's interest
in and to the Joint Assets and this Agreement, effective as of the date such
notice is given, to the remaining other Participating Interest Owners and such
defaulting Party shall be due no recompense whatsoever from such owners for such
relinquishment and assignment. Such defaulting Party's unpaid share of the Joint
Expenses prior to and after any such forfeiture, and such Party's forfeited
interest shall be allocated proportionately to the then remaining other
Participating Interest Owners by Operator using the same proportionate
allocation methodology employed in Sections 9.01 and 9.02 above with respect to
allocation of Relinquished Interests and Partial Relinquished Interests (with
necessary changes in points and details) and such then remaining other owners
shall have no right to decline such allocation and shall pay their respective
proportionate shares of such unpaid share within 15 days of each such owner's
receipt of operator's notice of such allocation and accompanying invoice. Should
such a default by such a Party occur during the Production Program and remain
uncured for a period of 365 consecutive days after Operator's notice of default,
operator shall have the same right to effect forfeiture of such Party's
interests as hereinabove provided in this paragraph with respect to default
during the Exploration and Development Programs; provided, however, that in
addition to such right to effect forfeiture, Operator shall have the right prior
to such forfeiture, exercisable at the time notice of default is given to such
Party, to sell such Party's share of sulphur produced during the period
following Operator's notice of default for the purpose of applying the proceeds
of such sale to such Party's unpaid share of the Joint Expenses during such
period, and Operator shall have no obligation to account to any such Party for
any of such proceeds so applied.

                                   XX.  TERMINATION

    20.01     EVENTS OF TERMINATION.  This Agreement shall terminate upon the
earlier to occur of the following:

              (a)  The mutual agreement of the Parties;

              (b)  Such time as none of the Parties own jointly any interest in 
                   the Property;

              (c)  The fiftieth anniversary of the Effective Date.

    20.02     PROCEDURE.  Upon termination of this Agreement pursuant to (a) or
(c) or Section 20.01, the Parties shall satisfy all liabilities resulting from
Joint operations, including but in no way limited to expenditures that Operator
has firmly committed to make pursuant to an approved Work Plan and Budget, and
shall sell or otherwise agree on the disposition of all Joint Assets other than
the Property. All liabilities and expenses shall be several and not joint and
shall be borne and paid by the Parties in proportion to their respective
Participating Interests. The proceeds of sale shall be distributed to the
Parties in proportion to their Participating Interests. At termination the
Parties shall retain their undivided interests in the Property as joint owners,
equal to their respective Participating Interests therein, and such undivided
interests shall cease being subject to the terms and conditions of this
Agreement. The Parties shall execute such assignments and cross-assignments as
may be necessary to reflect their ownership of their undivided interests in the
Property. Upon termination, the Policy Committee, or its appointee, shall have
the right and authority to take all action necessary to wind up the activities
being terminated and all costs and expenses so incurred by the Policy Committee,
or its appointee, shall be expenses for the Joint Account. Termination of this
Agreement shall not relieve any Party from any liability that has accrued or
attached prior to the date of such termination.

    20.03     RECLAMATION AND ABANDONMENT SECURITY.  Unless prior to the
commencement of Steaming Operations the Parties agree to another procedure to be
utilized for charging abandonment and reclamation costs to the Joint Account
(examples of other possible procedures set forth hereinbelow), Operator shall
charge each Non-Operator, in each monthly billing to such Non-Operator after
Steaming Operations commence, an amount equal to such Non-

                                  19
<PAGE>

Operator's proportionate share of the total cost for abandonment and 
reclamation of the Property and Joint Assets (including costs required by 
government or other authority) apportioned ratably over the Operator's 
estimated life of commercially producible reserves at the Mine as such cost 
may be reasonably estimated by Operator and revised from time to time as 
operator shall deem necessary.

EXAMPLES:

    A.   The Operator will charge the Joint Account monthly with a reasonably
         estimated cost for abandonment and reclamation, including costs
         required by government or other authority. In so doing receivable
         accounts for each Party will be debited for each Party's proportionate
         share of such charges and a reserve account will be credited for the
         total monthly charge. Each Non-Operator will post a bond with the
         Operator for its proportionate share of the total estimated
         abandonment and reclamation costs. As required, such bonds will be
         revised to reflect each Non-Operator's proportionate share of revised
         abandonment and reclamation costs. At the time abandonment and
         reclamation costs are incurred by the Operator, each Party will be
         billed its proportionate share of such costs. Cash remitted to the
         operator in payment of such billings will be applied against each
         Party's receivable account. At the end of the operating life of the
         Joint Operations, the difference between the total abandonment costs
         incurred and the total charges to the reserve account will be charged
         or credited to the reserve account of the Parties' receivable accounts
         in proportion to their respective interests.

    B.   A reasonably estimated cost for abandonment and reclamation of the
         Joint Property, including costs required by government or other
         regulatory authority, will be provided for in the Joint Account and
         included in a reserve account. A charge for these estimated costs will
         be included by the Operator in each monthly billing to the
         Non-Operators. Interest will be earned on the total reserve account
         balance and credited to the Joint Account on a monthly basis based
         upon an interest rate to be agreed to by the Parties. At the end of
         the operating life of the Joint Operations, the difference between the
         total abandonment and reclamation costs incurred and the total charged
         to the reserve account will be charged or credited to the Joint
         Account.

                              OPERATING AGREEMENTS

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


     THIS AGREEMENT (the "Agreement") made and entered into between Freeport-
McMoRan Resource Partners, Limited Partnership, a Delaware limited partnership
(sometimes "FMRP" and sometimes "Operator") , IMC Fertilizer, Inc., a Delaware
corporation ("IMC") , and Felmont Oil Corporation, a Delaware corporation
("Felmont"), FMRP, IMC and Felmont hereinafter each a "Party" and collectively
the "Parties", as the owners in indivision in the percentages, respectively, of
58.33%, 25%, and 16.67% of the following described rights and interests:

     A.   That certain Sulphur and Salt Lease, designated by Serial No. OCS-G
          9372, granted effective as of May 1, 1988 by the United States
          Department of the Interior, Minerals Management Service, as Lessor, to
          Freeport-McMoRan Resource Partners, Limited Partnership, IMC
          Fertilizer, Inc., and Felmont Oil Corporation, as Lessee, covering
          lands described as follows:

               All of Block 299, Main Pass Area, South and East
               Addition, OCS Leasing Map, Louisiana Map No. 10A.

          hereinafter referred to as the "Sulphur Lease";

     B.   That certain Oil and Gas Lease, designated by Serial No. OCS-G 1316A,
          granted by the United States of America, as lessor, to Freeport-
          McMoRan Resource Partners, Limited Partnership, as lessee, effective
          June 5, 1990, covering and affecting the therein described portion of
          Block 299, Main Pass Area, South and East Addition, as shown on
          official leasing map La. No. 10A, Outer Continental Shelf Leasing Map,
          Louisiana Offshore operations.

which lease is hereinafter referred to as the "Oil and Gas Lease", to-wit:

     WHEREAS, the Parties entered into an operating agreement dated May 1, 1988,
designating FMRP as Operator, governing their exploration, development,
production and transportation of sulphur under the Sulphur Lease, such operating
agreement hereinafter being referred to as the "Sulphur Agreement"; and

     WHEREAS, the Parties entered into an operating agreement dated of even date
herewith, designating FMRP as the Operator, governing their exploration,
development, production and transportation of oil and gas under the Oil and Gas
Lease, said operating agreement hereinafter being referred to as the "Oil and
Gas Agreement"; and

     WHEREAS, the Parties recognize that the development and production of oil
and gas from the Oil and Gas Lease in certain respects will be unusual and
different from oil and gas operations normally conducted Offshore Louisiana due
to the shallow subsea depth of the oil and gas reserves, the location of oil and
gas reserves on top of a salt dome and in the same formations, horizons and
zones in which sulphur deposits are present and from which sulphur is to be
mined and produced along with the oil and gas, and that the technical and
engineering problems likely to be encountered in the operations and facilities
for the development and production of oil and gas from the Oil and Gas Lease may
involve or require technology which is unusual and novel with respect to oil and
gas operations Offshore Louisiana, the results of which have not been proven by
usage or experience: and

     WHEREAS, it is the desire and intent of the Parties that such oil and gas
reserves be developed and produced in coordination with the sulphur reserves,
utilizing the technology and facilities which are customary for the development
and production of sulphur and for the development and production of oil and gas,
it being recognized, however, that it is necessary for the operations for the
development and production of the sulphur reserves and the oil and gas reserves
to be closely coordinated to insure the optimum total net value of the combined
sulphur reserves and oil and gas reserves consistent with safety and
conservation of the natural resources.


<PAGE>

     NOW, THEREFORE, in consideration of the premises, and for the mutual
benefit of the Parties hereto, the Parties agree that they will coordinate the
exploration, development, production and transportation under the Sulphur Lease
and the Oil and Gas Lease in accordance with the terms of the Sulphur Agreement
and the oil and Gas Agreement, respectively, by modifying and amending those
agreements as hereinafter set out.

     A.   UNITY OF OWNERSHIP

          The Parties recognize that continuity of the joint ownership among
themselves, their successors and assigns, is essential to the efficient
operation of the above described leases with the undivided interest owned by
each Party being and remaining identical in both the Sulphur Lease and the Oil
and Gas Lease. To that effect, no Party shall sell, assign, transfer or
otherwise dispose of its interest in either the Sulphur Lease or the Oil and Gas
Lease, or in any agreements relating to the ownership of, operations on or
production from such leases, including the Sulphur Agreement and the Oil and Gas
Agreement, unless it simultaneously sells, assigns, transfers or otherwise
disposes to the acquiring party an identical interest in the other lease and
related agreements. Any sale, assignment, transfer or other disposition by a
Party shall be made under the terms and provisions of the respective Operating
Agreements and must specifically be made subject thereto as such agreements are
modified and amended herein. Notwithstanding any of the foregoing, this
paragraph shall not be construed to prevent a party from granting a mortgage,
pledge or other security interest affecting one but not the other of (i) the
Sulphur Lease and related agreements and (ii) the Oil and Gas Lease and related
agreements, nor shall it be construed to prevent a party from assigning,
pledging or granting a security interest in such party's share of sulphur or oil
and gas production or the proceeds therefrom.

     B.   COORDINATING POLICY COMMITTEE

          The Parties shall establish a Coordinating Policy Committee ("CPC") to
be composed of one representative designated by each Party which is a party to
both the Sulphur Agreement and the Oil and Gas Agreement, for the purpose of
coordinating the exploration, development, production, transportation and
abandonment operations under the Sulphur Lease and the Oil and Gas Lease in the
manner hereinbelow provided.

          A representative designated pursuant to this provision shall serve
until replaced by the Party that designated such representative. Each Party also
may designate one or more alternates for any representative designated by it. An
alternate shall exercise voting rights only in the event of a representative's
absence. Each representative may bring to CPC meetings such advisors as the
representative deems necessary or desirable; however, such advisors shall have
no right to vote on matters before the CPC.

          Each Party promptly shall advise the other Parties in writing as to
the names and addresses of its representative and alternate representative who
shall have the authority to represent and bind the advising Party with respect
to any matter to be acted upon by the Policy Committee. A Party's representative
or alternate representative may be changed from time to time upon written notice
to the other Parties.

          The Operator for each Operating Agreement will submit to the CPC the
Work Plan and Budget for the following calendar year for the particular
operating agreement as soon as it is approved, but not later than November 15th
of each year. The CPC will review such Work Plans and Budgets to be assured that
there are no provisions therein which would result in a conflict between the two
operations, and, in such event, will approve and adopt such Work Plans and
Budgets. Should the CPC believe that there is a conflict or a potential conflict
between the two Work Plans and Budgets, it shall work to an acceptable
modification of one or both so as to remove such conflict or potential conflict
and, thereupon, shall approve and adopt both Work Plans and Budgets as modified.

          Should the Parties to either operating agreement be unable to agree on
the Work Plan and Budget for the following calendar year by November 15th of the
preceding year, the alternate proposals shall, at that time, be referred to the
CPC which shall work to the resolution thereof and the approval of the
particular Work Plan and Budget. Upon such approval, the CPC shall proceed to a
review of both Work Plans and Budgets for possible conflicts, approving both if
no conflict is found or, in the event of a potential conflict, working to an
acceptable modification one 

<PAGE>

or both of the Work Plans and Budgets so as to remove such conflict as 
potential conflict and, thereupon, shall approve and adopt both Work Plans 
and Budgets as modified.

          The Work Plan and Budget for the Sulphur Lease for all of the calendar
year of 1990 has been approved and adopted by the Parties and the Work Plans and
Budgets for the Oil and Gas Lease for the calendar years of 1990 and 1991 have
been approved and adopted by the Parties, and such Work Plans and Budgets are to
be implemented as approved and adopted.

          The CPC shall also approve all supplements and revisions to the Work
Plans and Budgets, and the actions taken to wind up the activities and
operations on either lease under the provisions of its applicable operating
agreement, all in the manner provided above.

          Special meetings shall be called by operator as and when the operator
should deem necessary. Any other Party shall have the right to call a special
meeting provided that no such special meeting shall be called sooner than three
months after the last such special meeting. During the fifth month of each
Budget Year the operator shall call an advisory meeting for the sole purpose of
informing the CPC of the progress of operations for the current Budget Year to
date. The Parties shall attend all regular, special and advisory meetings of the
CPC. All meetings shall be held at Operator's offices, unless all Parties agree
to another location. Written notice of the time and place of each regular,
special and advisory meeting, shall be submitted by the Operator to the Parties,
not less than 15 days before any such meeting, unless such requirement of notice
is waived in writing by the Parties. The holding of any advisory meeting may be
waived provided all Parties consent to such waiver.

          The designated representative, or alternate, of operator shall act as
chairman at all CPC meetings. Each Party shall bear its own cost of attendance.
If Operator deems it necessary for any personnel who are assigned duties in
connection with the conduct of operations to attend any meeting, the additional
cost incurred therefor shall be charged to the Joint Account of the operating
agreement on whose behalf such personnel is appearing.

          Only those Parties owning an interest of ten percent (10%) or more in
both leases may vote on matters before the CPC. CPC approval of any matter
requiring CPC approval hereunder, shall require the vote of Operator and the
vote of at least one other Party entitled to vote which is not an affiliate of
Operator; provided, however, that if only one Party other than Operator should
be entitled to vote then CPC approval of any such matter shall require only the
vote of Operator.

          With respect to any matter submitted for CPC approval, should Operator
be unable to obtain a concurring vote to its proposal of at least one other
party entitled to vote, then in such event all Parties entitled to vote shall
continue good faith negotiations to resolve outstanding differences. In the
event the CPC is unable to secure approval of proposed Work Plans and Budgets
within 60 days, the Operator shall submit alternate proposed Work Plans and
Budgets and the Parties shall vote and negotiate thereon until approval is
obtained. In any event, until CPC approval of Work Plans and Budgets, Operator
is authorized to continue operating the Sulphur Lease for the joint account of
the Sulphur Agreement in accordance with its latest approved Work Plan and
Budget, and to continue operating the Oil and Gas Lease in the manner provided
in the second paragraph of Section 8.5 of the Oil and Gas Agreement. No formal
CPC approval shall be necessary for such expenditures or for such operations.
Upon approval of the Work Plans and Budgets they shall be implemented and
followed.

          In lieu of deciding any matter at any meeting, the CPC (a) may act by
instrument(s) in writing signed by the representative of each Participating
Interest Owner, which instrument(s) (in one or more counterparts) shall be
conclusively deemed to be the act of the CPC, or (b) by telephone communication
provided that such action is unanimous and is confirmed in writing by each Party
or each Party's representative.

          A Work Plan and Budget for both the Sulphur Lease and the Oil and Gas
Lease must be adopted by the CPC before the adoption of either Work Plan and
Budget shall become effective. At such time as a Work Plan and Budget for both
the Sulphur Lease and the Oil and Gas Lease have been adopted by the CPC, it
shall be binding on all Parties as adopted and shall then be implemented as to
each the Sulphur Lease and the Oil and Gas Lease under the 

<PAGE>

terms and conditions provided therefor in the Sulphur Agreement and the Oil. 
and Gas Agreement, respectively, and may not be changed except by action of 
the CPC provided for herein.

          Each capitalized term herein shall have the same meaning as in the Oil
and Gas Agreement unless such term is defined herein or a different meaning is
otherwise clearly indicated.

     C.   DEFAULTS

          Reference is made to Article XIX of the Sulphur Agreement and to
Article XXI of the Oil and Gas Agreement. The Parties agree that a default under
the Sulphur Agreement by any Participating Interest Owner (as defined therein),
which activates the provisions of the second paragraph of Article XIX thereof
shall be grounds for a default under the provisions of Article XXI of the Oil
and Gas Agreement, but with the sole and limited effect of conferring on the
Operator of the Sulphur Agreement the right under the provisions of Section 21.2
of the oil and Gas Agreement ("Section 21.2") to have the proceeds from the sale
of production of oil and gas accruing to the defaulting party paid to the
operator of the Oil and Gas Agreement and remitted to the Operator of the
Sulphur Agreement in discharge of the defaulting Participating Interest Owner's
unpaid share of the Joint Expenses under the Sulphur Agreement. The Operator of
the Sulphur Agreement may exercise such right by requesting in writing that the
operator of the Oil and Gas Agreement collect from purchasers of oil and gas the
proceeds identified in Section 21.2 and remit the proceeds to the Operator of
the Sulphur Agreement; provided, however, that no such collection or remittance
of proceeds shall occur unless the defaulting party receives at least fifteen
(15) days prior written notice thereof from the Operator of the Oil and Gas
Agreement and does not cure the default within such fifteen (15) day period.

          Neither the Operator of the Sulphur Agreement nor the Operator of the
Oil and Gas Agreement shall have any other right or remedy with respect to the
working interest or interests in the Property of the defaulting party under the
Oil and Gas Agreement as a consequence of a default under the Sulphur Agreement,
nor shall any default under the Sulphur Agreement give rise under any
circumstances to any foreclosure, or the like, or the defaulting party's working
interest or interests in the Property under the Oil and Gas Agreement.

          Conversely, the Parties agree that a default of any party under the
Oil and Gas Agreement which activates the provisions of Section 21.2 shall be
grounds for a default under the provisions of the second paragraph of Article
XIX of the Sulphur Agreement, but with the sole and limited effect of conferring
on the operator of the Oil and Gas Agreement the right to have sold the
defaulting party's share of sulphur produced after the notice of default
provided for in such paragraph is given, and the proceeds from such sale
remitted to the Operator of the Oil and Gas Agreement in discharge of such
defaulting party's delinquent obligations under the Oil and Gas Agreement. The
Operator of the Oil and Gas Agreement may exercise such right after expiration
of the fifteen (15) day period provided for in Section 21.2 by requesting in
writing that the Operator of the Sulphur Agreement sell such defaulting party's
share of such sulphur and remit the proceeds from such sale to the Operator of
the Oil and Gas Agreement; provided, however, that no such sale or remittance
shall take place unless the defaulting party has received at least fifteen (15)
days prior written notice of such sale from the Operator of the Sulphur
Agreement and does not cure the default within such fifteen (15) day period.
Neither the operator of the Oil and Gas Agreement nor the Operator of the
Sulphur Agreement shall have any other right or remedy with respect to the
Participating Interest or share of sulphur of the defaulting party arising as a
consequence of a default under the Oil and Gas Agreement, nor shall any default
arising under the oil and Gas Agreement give rise under any circumstances to any
forfeiture, foreclosure, or the like, of the defaulting party's Participating
Interest under the Sulphur Agreement.

          Neither the Operator of the Sulphur Agreement nor of the oil and Gas
Agreement shall be required to comply with the request from the other pursuant
to this subparagraph C, if a defaulting party is in default under both
Agreements. Any Operator may cease honoring such a request from the other
Operator at such time as any party in default under one Agreement defaults under
the other. It is the intention of the Parties hereto that each Operator shall
have priority in enforcing default under its Agreement against one of its own
participating Interest Owners or parties, as the case may be.

<PAGE>

D.   CONFLICTS

          To the extent necessary, the Sulphur Agreement and the Oil and Gas
Agreement are amended and modified to conform with the terms and provisions
hereof. Consequently, in the event of any conflict between the terms and
provisions of this Agreement and those of either the Sulphur Agreement or the
Oil and Gas Agreement, the terms and provisions of this Agreement shall prevail.

E.   GENERAL PROVISIONS

     (a)  This Agreement shall be binding upon and inure to the benefit of the
          Parties and their respective successors and assigns. This Agreement
          may not be assigned by any Party without the written consent of all
          other Parties being first had and obtained, except any assignments
          that are consistent with assignments made pursuant to the Sulphur
          Agreement and the Oil and Gas Agreement.

     (b)  In the event that the interests of any Party in the Sulphur Lease and
          the Oil and Gas Lease become subject to separate ownership as the
          result of the foreclosure of any separate mortgage, pledge, or
          security interest permitted under Section A hereof or as a result of
          the transfer of any interest in the Sulphur Lease or the Oil and Gas
          Lease by deed in lieu of foreclosure of any separate mortgage, pledge,
          or security interest permitted under Section A hereof, this Agreement
          shall remain in full force and effect and shall remain binding upon
          all other Parties. Further, in the event that a single entity
          subsequently becomes the owner of such separate interests in the
          Sulphur Lease and the Oil and Gas Lease, such entity shall be a Party
          hereunder and this Agreement shall be binding upon such Party.

     (c)  This Agreement shall be considered an amendment to both the Sulphur
          Agreement and the Oil and Gas Agreement and may not be amended except
          by an agreement in writing executed by all the Parties.

     (d)  This Agreement shall be construed and enforced in accordance with the
          laws of the State of Louisiana and the United States.

     EXECUTED this 5th day of June, 1990, but effective as of the 5th day of
June, 1990.

next to the Tampa Average Sulphur Price for that Quarterly Period; PROVIDED
that: 

          (i)  if the Tampa Average Sulphur Price for a Quarterly Period falls
     between any two prices shown on SCHEDULE 1.1, the Quarterly Installment
     Payment for that Quarterly Period will be determined by interpolation
     between the "Quarterly Installment Payment" amounts shown on SCHEDULE 1.1
     next to those two prices;

         (ii)  if the first and/or last Quarterly Period covers only a portion
     of a full calendar quarter, the Quarterly Installment Payment for that
     Quarterly Period will be determined by multiplying the Quarterly
     Installment Payment that would be payable if that Quarterly Period covered
     a full calendar quarter by a fraction of which (A) the numerator is the
     number of days in that Quarterly Period and 


                                        8

<PAGE>

     (B) the denominator is the number of days in the full calendar quarter of

     the twentieth anniversary of the Closing Date, 

               (A)  FRP calculates the Quarterly Installment Payment that would
          be due for such Quarterly Period but for the adjustment required by
          this Section (iii) (such amount being referred to as the "PRE-
          ADJUSTMENT AMOUNT") and 

               (B)  the number of tons of sulphur with respect to which the
          calculation of the Pre-Adjustment Amount would be deemed to be made
          (the "PRO FORMA TONNAGE"), when added to the aggregate number of tons
          of sulphur with respect to which calculations of Quarterly Installment
          Payments are deemed to have been made in all previous Quarterly
          Periods, would exceed 18.6 million tons (such excess being referred to
          as the "EXCESS TONNAGE"), then the Quarterly Installment Payment for
          that Quarterly Period will be calculated by multiplying the Pre-
          Adjustment Amount by a fraction of which (I) the numerator is obtained
          by subtracting the Excess Tonnage from the Pro Forma Tonnage and (II)
          the denominator is the Pro Forma Tonnage. 

          For purposes of this calculation, the number of tons of sulphur with
respect to which a calculation of the Quarterly Installment Payment due in any
Quarterly Period will be deemed to have been made is the amount shown on
SCHEDULE 1.1 under the column "Deemed Quarterly Volumes" next to the Tampa
Average Sulphur Price for that Quarterly Period, PROVIDED that (i) if the Tampa
Average Sulphur Price for that Quarterly Period is between any two prices shown
on SCHEDULE 1.1, the number of such tons shall be determined by interpolating
between the Deemed Quarterly Volumes shown on SCHEDULE 1.1 next to those two
prices, (ii) if the first Quarterly Period covers only a portion of a full
calendar quarter, the number of tons of sulphur with respect to which a
calculation of the Quarterly Installment Payment due in that Quarterly Period
will be deemed to have been made will be determined by multiplying the number of
such tons as to which a 


                                        9

<PAGE>

calculation would have been made if that Quarterly Period had covered a full
calendar quarter by a fraction of which (A) the numerator is the number of days
in that Quarterly Period and (B) the denominator is the number of days in the
full calendar quarter of which that Quarterly Period is a part. 

          "QUARTERLY PERIOD" means a calendar quarter during the period
commencing on the day after the Closing Date and ending on the earlier of (iv)

tons of sulphur, as contemplated by Section (iii) of the definition of
"Quarterly Installment Payment"; PROVIDED that if the Closing Date does not
occur on the last day of a calendar quarter: 

          (A)  the first Quarterly Period will commence on the day after the
     Closing Date and end on the last day of the calendar quarter during which
     the Closing Date occurs; and 

          (B)  unless the last Quarterly Period is the period contemplated by
     Section (v) of this definition, the last Quarterly Period will commence on
     the first day of the calendar quarter in which the twentieth anniversary of
     the Closing Date falls and end on such twentieth anniversary.

          "REGULATED ENVIRONMENTAL ACTIVITY" means any generation, treatment,
storage, recycling, transportation or Release of any Hazardous Substance, as
such activities are regulated under Environmental Laws.

          "RELEASE" means any "release" as such term as defined in CERCLA at 42

          "TAMPA AVERAGE SULPHUR PRICE" means for any Quarterly Period the
average market price per ton for sulphur FOB Tampa Terminal during that
Quarterly Period calculated by (i) FIRST, taking the arithmetic average of the
high and low Tampa Contract prices, as published in "Green Markets", for each
week that is partially or wholly within that Quarterly Period (each such average
being referred to as a "WEEKLY AVERAGE") and (ii) SECOND, calculating the
arithmetic average of the Weekly Averages for all 


                                       10

<PAGE>

weeks that are partially or wholly within that Quarterly Period; PROVIDED that
if any Weekly Average relates to a week of which only part is within that
Quarterly Period, the weight given to that Weekly Average in calculating this
arithmetic average will be proportionately reduced to reflect the portion of
such week that is within the Quarterly Period.  If "Green Markets" ceases
publication or the required prices are no longer published or if the prices
published in "Green Markets" are no longer representative of prevailing contract
sulphur prices in Tampa, FRP and Pennzoil shall agree on an alternative basis
for determining the Tampa Average Sulphur Price in accordance with the
procedures set forth in Section 2.11 of this Agreement. 

          "TAMPA FACILITY" means (i) Pennzoil's facility in Hillsborough County,

     pipe) located in the plant area at the Culberson Facility as well as any
     asbestos containing material located elsewhere at the Culberson Facility. 
     Pennzoil shall retain responsibility for such abatement for asbestos-
     insulated pipe in excess of 


                                       18

<PAGE>

     14,000 linear feet located in the plant area at the Culberson Facility.

          2.4  EXCLUDED LIABILITIES.  Notwithstanding any provision in this
Agreement or any other writing to the contrary, FRP is assuming only the Assumed
Liabilities and is not assuming any other liability or obligation of Pennzoil
(or any predecessor owner of all or part of the Business and the Purchased
Assets) of whatever nature, whether presently in existence or arising hereafter
and whether accrued, contingent, absolute, determined, determinable or
otherwise, actual or potential, known or unknown.  All such other liabilities
and obligations shall be retained by and remain obligations and liabilities of
Pennzoil (all such liabilities and obligations not being assumed being herein
referred to as the "EXCLUDED LIABILITIES"), and, without in any way limiting
this Section 2.4, none of the following shall be Assumed Liabilities for
purposes of this Agreement:  (a) all accounts payable attributable to the
operation of the Business prior to the Closing Date and all obligations with
respect to any Debt; (b) any obligation or liability for Tax arising from or
with respect to the Purchased Assets or the operations of the Business which is
incurred in or attributable to the Pre-Closing Tax Period; (c) any liabilities
or obligations relating to employee benefits or compensation arrangements with
respect to any Pennzoil employee who is not a Transferred Employee or with
respect to any Transferred Employee for any period on or prior to the Transfer
Date for such Transferred Employee; (d) except as provided in Sections 2.3(e)
and 2.3(f), any Environmental Liability; (e) any liability or obligation
relating to an Excluded Asset; and (f) subject to Section 11.2, any other
obligation or liability associated with the Business or the operation of the
Purchased Assets on or prior to the Closing Date.

          2.5  ASSIGNMENT OF CONTRACTS AND RIGHTS.  Anything in this Agreement
to the contrary notwithstanding, this Agreement shall not constitute an
agreement to assign any Purchased Asset or any claim or right or any benefit
arising thereunder or resulting therefrom if an attempted assignment thereof,
without the consent of a third party thereto, would constitute a breach or other
contravention thereof or in any way adversely affect the rights of FRP or
Pennzoil thereunder.  Pennzoil and FRP will use all commercially reasonable
efforts (but without any obligation on the part of Pennzoil or FRP to pay money)
to obtain the 


                                       19

<PAGE>

consent of the other parties to any such Purchased Asset or any claim or right
or any benefit arising thereunder for the assignment thereof to FRP.  If such
consent is not obtained, or if an attempted assignment thereof would be
ineffective or would adversely affect the rights of Pennzoil thereunder so that
FRP would not in fact receive all such rights, Pennzoil and FRP will cooperate
in a mutually agreeable arrangement under which FRP will obtain the benefits and
assume the obligations thereunder in accordance with this Agreement, including
sub-contracting, sub-licensing or sub-leasing to FRP, or under which Pennzoil
will enforce for the benefit of FRP, with FRP assuming Pennzoil's obligations,
any and all rights of Pennzoil against a third party thereto; PROVIDED, HOWEVER,
that Pennzoil does not guarantee performance by any other party to a Purchased
Asset.  Pennzoil will promptly pay to FRP when received all monies received by
Pennzoil under any Purchased Asset or any claim or right or any benefit arising
thereunder, except to the extent the same represents an Excluded Asset.

          2.6  OTHER SULPHUR PROPERTIES.  (a)  Pennzoil hereby grants FRP an
exclusive option, effective from and after the date of this Agreement and
through the date six months after the Closing Date, to acquire some or all of
the properties listed on SCHEDULE 2.6, including the lands they cover, all
interests in the surface and minerals and all appurtenant rights, interests and
properties (collectively, the "OTHER SULPHUR PROPERTIES"), on the terms provided
in this Section 2.6.  Pennzoil represents that the Other Sulphur Properties
constitute all of the properties owned by Pennzoil, other than the Real Property
and the Mineral Interests described in SCHEDULES 3.8(a) OR 3.8(b), that are now
predominantly sulphur prospects or properties.

          (b)  To exercise the option, FRP must give written notice, identifying
the Other Sulphur Property or Properties FRP wishes to acquire, to Pennzoil at
any time from the date of this Agreement to the date six months after the
Closing Date.  On the date six months after the Closing Date the option shall
expire, except for Pennzoil's obligation to convey the Other Sulphur Properties
selected by FRP during the six-month option period.

          (c)  Within ten days after FRP gives each such written notice to
Pennzoil, Pennzoil shall convey to FRP the Other Sulphur Property or Properties
selected by FRP by form of conveyance substantially in the form of the
Conveyance, 


                                       20

<PAGE>

Assignment, Bill of Sale and Assumption Agreement, but without warranty of
title.  FRP shall be responsible for all Environmental Liabilities that relate
to the Other Sulphur Property or Properties selected by and conveyed to FRP.

          (d)  Each such conveyance shall be made without additional
consideration.

          2.7  PURCHASE PRICE.  (a)  In consideration for Pennzoil's sale of the
Purchased Assets to FRP, FRP agrees to pay to Pennzoil the Quarterly Installment
Payment for each Quarterly Period, subject, however, to Section 5.6 of the Deed
of Trust.  The Quarterly Installment Payment payable for each Quarterly Period
will be due on the date 45 days after the last day of that Quarterly Period (or,
if such date is not a Business Day, the next succeeding Business Day) and will
be accompanied by a schedule prepared by FRP showing, in reasonable detail, its
calculation of such Quarterly Installment Payment.  The obligation of FRP to
make Quarterly Installment Payments as provided above is referred to herein as
the "PURCHASE PRICE" for the Purchased Assets.

          (b)  On each Option Date, FRP will have the right, by notice given to
Pennzoil (a "CALL OPTION NOTICE") on or before the thirtieth day (or, if such
date is not a Business Day, the next succeeding Business Day) after such Option
Date, to acquire all rights to all Quarterly Installment Payments occurring
after that Option Date for an amount equal to the Option Price for that Option
Date (such right being referred to as the "CALL OPTION").  A Call Option Notice
shall be accompanied by a schedule prepared by FRP showing, in reasonable
detail, its calculation of the Option Price.  If FRP delivers a Call Option
Notice in respect of any Option Date, the Option Price shall be due on the date
45 days after that Option Date.  Payment of the Option Price shall satisfy in
full all of FRP's obligations to pay any Quarterly Installment Payments
occurring after the applicable Option Date, and all rights of Pennzoil to
receive any such Quarterly Installment Payments shall be extinguished.  

          (c)  If FRP does not exercise the Call Option with respect to any
Option Date by delivering a Call Option Notice on or before the thirtieth day
(or, if such date is not a Business Day, the next succeeding Business Day) after
such Option Date, Pennzoil will have the right, by notice given to FRP (a "PUT 


                                       21

<PAGE>

OPTION NOTICE") on or before the sixtieth day (or, if such date is not a
Business Day, the next succeeding Business Day) after such Option Date, to
require FRP to purchase all rights to all future Quarterly Installment Payments
for an amount equal to $10,000,000 (such right being referred to as the "PUT
OPTION"); PROVIDED that Pennzoil will not have any Put Option with respect to
any Option Date occurring after the earliest to occur of (i) the sixteenth
anniversary of the Closing Date and (ii) the date on which FRP has completed all
Quarterly Installment Payments.  If Pennzoil delivers a Put Option Notice in
respect of any Option Date, such amount shall be due on the date 75 days after
that Option Date (or, if such date is not a Business Day, on the next succeeding
Business Day).  Payment of the Option Price shall satisfy in full all of FRP's
obligations to pay any Quarterly Installment Payments occurring after the
applicable Option Date, and all rights of Pennzoil to receive any such Quarterly
Installment Payments shall be extinguished.  

          (d)  Each payment under this Section 2.7 shall be made by delivery by
FRP of a certified or official bank check payable in immediately available funds
to Pennzoil or by causing such payment to be credited to such account of
Pennzoil as Pennzoil may designate in writing from time to time.  Any payment
under this Section 2.7 that is not paid on the date when due shall bear interest
from and including the due date to but excluding the date of payment at a rate
per annum equal to the rate publicly announced from time to time by Chase
Manhattan Bank, N.A. in New York City (i) as its prime rate in the case of
payments as to which there exists a genuine dispute between the parties
regarding the amount of the payment or (ii) as its prime rate plus 2% in the
case of payments as to which no such genuine dispute exists, in each case during
the period from the due date to the date of payment.  Such interest shall be
payable at the same time as the payment to which it relates and shall be
calculated daily on the basis of a year of 365 days and the actual number of
days elapsed.

          (e)  Upon the payment of the last installment of the Purchase Price or
upon payment pursuant to the exercise of the Call Option or the Put Option, all
Liens under the Deed of Trust and all other Liens held by Pennzoil or its
assignee in the Purchased Assets shall be released and discharged automatically.
At any time and from time to time prior to such termination, the parties may
agree to a total or partial release of any such Lien


                                       22

<PAGE>

in the Purchased Assets.  Upon such total or partial release of any such Lien,
Pennzoil will execute and deliver to FRP such releases and other documents as
FRP shall reasonably request to evidence or effect such release.

          2.8  CLOSING.  The closing (the "CLOSING") of the purchase and sale of
the Purchased Assets and the assumption of the Assumed Liabilities hereunder
shall take place at the offices of Pennzoil in Houston as soon as possible, but
in no event later than 10 Business Days, after satisfaction of the conditions
set forth in Article 10, or at such other time or place as FRP and Pennzoil may
agree.  At the Closing (or from time to time thereafter), Pennzoil and FRP shall
enter into the Conveyance, Assignment, Bill of Sale and Assumption Agreement,
and Pennzoil shall execute, acknowledge and deliver to FRP such deeds, bills of
sale, endorsements, consents, assignments and other good and sufficient
instruments of conveyance and assignment (the "CONVEYANCE DOCUMENTS") as the
parties and their respective counsel shall deem reasonably necessary or
appropriate to vest in FRP Good Title in and to the Purchased Assets.  The
parties will also execute and deliver (i) the Deed of Trust, (ii) a Transition
Services Agreement and (iii) each other deed, certificate, agreement or other
document contemplated by this Agreement.  Any payment required under this
Section 2.8 and not made at the Closing shall bear interest at the rate per
annum equal to the rate publicly announced from time to time by Chase Manhattan
Bank, N.A. in New York City (i) as its prime rate in the case of payments as to
which there exists a genuine dispute between the parties regarding the amount of
the payment and (ii) as its prime rate plus 2% in the case of payments as to
which no such genuine dispute exists.

          2.9  ALLOCATION OF PURCHASE PRICE FOR TAX PURPOSES.  (a) The parties
agree that for tax purposes, the Purchase Price will be deemed to be
$22,500,000.  As soon as practicable after the Closing Date, FRP shall deliver
to Pennzoil a statement (the "ALLOCATION STATEMENT"), setting forth the value of
the Purchased Assets for tax purposes which shall be used for the allocation of
the Purchase Price (together with the Assumed Liabilities) among the Purchased
Assets.

          (b)  Pennzoil shall have a period of 30 days after the delivery of the
Allocation Statement to present in writing to FRP notice of any objections
Pennzoil may have to the allocation set 


                                       23

<PAGE>

forth in the Allocation Statement.  Unless Pennzoil timely objects, the
Allocation Statement shall be binding on the parties without further adjustment.

          (c)  If Pennzoil shall raise any objections within the 30 day period,
FRP and Pennzoil shall negotiate in good faith and use their best efforts to
resolve such dispute.  If the parties fail to agree within 5 days after the
delivery of the notice, then the disputed items shall be resolved by Arthur
Andersen, or if such firm declines to act in such capacity, by such other firm
of independent nationally recognized accountants chosen and mutually accepted by
both parties (the "ACCOUNTING REFEREE").  The Accounting Referee shall resolve
the dispute within 30 days of having the item referred to it.  The costs, fees
and expenses of the Accounting Referee shall be borne equally by Pennzoil and
FRP.

          (d)  Pennzoil and FRP agree to report an allocation of the Purchase
Price among the Purchased Assets in a manner entirely consistent with the
Allocation Statement and agree to act in accordance with such Allocation
Statement in the preparation and filing of all tax returns (including without
limitation filing Form 8594 with its Federal income tax return for the taxable
year that includes the date of the Closing) and in the course of any tax audit,
tax review or tax litigation relating thereto.

          (e)  Not later than 10 days prior to the filing of their respective
Form 8594 relating to this transaction, each party shall deliver to the other
party a copy of its Form 8594.
          
          2.10 LIQUID SULPHUR INVENTORY ADJUSTMENT.  (a) On the Closing Date (or
on such other date or dates as close as possible to the Closing Date as may be
mutually agreed by the parties, one or more representatives designated by each
of Pennzoil and FRP (who may be employees or officers of Pennzoil or FRP, as the
case may be) shall jointly conduct on behalf of each party respectively a
measurement by tank strapping of the level of Pennzoil's liquid sulphur
inventory (net of any sulphur owned by parties other than Pennzoil and any
sulphur that is sold on Pennzoil's books as of the Closing Date) included in the
Purchased Assets at Closing (the "CLOSING SULPHUR INVENTORY").  Inventory in
transit, including in tank cars and barges, will be measured by tank strapping
at destination and will be deemed to 


                                       24

<PAGE>

be at its destination as of the Closing Date.  If the parties' respective
measurements of Pennzoil's liquid sulphur inventory at the Tampa Facility, the
Galveston Facility, the Culberson Facility and/or Pennzoil's Savannah facility
differ, the level of inventory at that facility shall be the average of the
parties' respective measurements for that facility. 

          (b)(i)  Subject to Section 2.10(b)(v) below, if the Closing Sulphur
Inventory at the Tampa Facility is greater than the Tampa Base Sulphur
Inventory, then FRP shall pay to Pennzoil a cash amount equal to the difference
multiplied by the Tampa Average Sulphur Price as of the Closing Date minus
$3.75; if the Closing Sulphur Inventory at the Tampa Facility is less than the
Tampa Base Sulphur Inventory then Pennzoil shall pay to FRP a cash amount equal
to the difference multiplied times the Tampa Average Sulphur Price as of the
Closing Date minus $3.75 (the payment under this Section 2.10(b)(i) being the
"TAMPA ADJUSTMENT").

            (ii)  Subject to Section 2.10(b)(v) below, if the Closing Sulphur
Inventory at the Galveston Facility is greater than the Galveston Base Sulphur
Inventory, then FRP shall pay to Pennzoil a cash amount equal to the difference
multiplied by the Tampa Average Sulphur Price as of the Closing Date minus
$17.75; if the Closing Sulphur Inventory at the Galveston Facility is less than
the Galveston Base Sulphur Inventory, then Pennzoil shall pay to FRP a cash
amount equal to the difference multiplied times the Tampa Average Sulphur Price
as of the Closing Date minus $17.75 (the payment under this Section 2.10(b)(ii)
being the "GALVESTON ADJUSTMENT").

           (iii)  Subject to Section 2.10(b)(v) below, if the Closing Sulphur
Inventory at the Culberson Facility is greater than the Culberson Base Sulphur
Inventory, then FRP shall pay to Pennzoil a cash amount equal to the difference
multiplied by the Tampa Average Sulphur Price as of the Closing Date minus
$39.50; if the Closing Sulphur Inventory at the Culberson Facility is less than
the Culberson Base Sulphur Inventory, then Pennzoil shall pay to FRP a cash
amount equal to the difference multiplied times the Tampa Average Sulphur Price
as of the Closing Date minus $39.50 (the payment under this Section 2.10(b)(iii)
being the "CULBERSON ADJUSTMENT").


                                       25

<PAGE>

            (iv)  Subject to Section 2.10(b)(v) below, if the Closing Sulphur
Inventory at Savannah is greater than the Savannah Base Sulphur Inventory, then
FRP shall pay to Pennzoil a cash amount equal to the difference multiplied by
the Tampa Average Sulphur Price as of the Closing Date plus $2.75; if the
Closing Sulphur Inventory at Pennzoil's Savannah facility is less than the
Savannah Base Sulphur Inventory, then Pennzoil shall pay to FRP a cash amount
equal to the difference multiplied times the Tampa Average Sulphur Price as of
the Closing Date plus $2.75 (the payment under this Section 2.10(b)(iv) being
the "SAVANNAH ADJUSTMENT").

             (v)  The dollar amount of the Tampa Adjustment, the Galveston
Adjustment, the Culberson Adjustment and the Savannah Adjustment shall be
netted, and, if the Closing Sulphur Inventory is greater than the Base Sulphur
Inventory, the net amount shall be adjusted in FRP's favor by 50 percent of the
royalties payable on such excess inventory.  Pennzoil shall pay to FRP, or FRP
shall pay to Pennzoil, as the case may be, the net adjusted amount in the manner
and with interest as provided in Section 2.10(c).  Any such payment of the net
adjusted amount pursuant to this Section 2.10(b) shall be made at a mutually
convenient time and place within 20 days after the Closing Date.

          (c)  Any payments pursuant to this Section 2.10 shall be made by
delivery by FRP, or Pennzoil, as the case may be, of a certified or official
bank check payable in immediately available funds to the other party or by
causing such payments to be credited to such account of such other party as may
be designated by such other party.  The amount of any payment to be made
pursuant to this Section 2.10 shall bear interest from and including the due
date to but excluding the date of payment at a rate per annum equal to the rate
publicly announced from time to time by Chase Manhattan Bank, N.A. in New York
City (i) as its prime rate in the case of payments as to which there exists a
genuine dispute between the parties regarding the amount of the payment and (ii)
as its prime rate plus 2% in the case of payments as to which no such genuine
dispute exists, in each case during the period from the Closing Date to the date
of payment.  Such interest shall be payable at the same time as the payment to
which it relates and shall be calculated daily on the basis of a year of 365
days and the actual number of days elapsed.


                                       26

<PAGE>

          (d)  If Pennzoil advises FRP that the relative amounts of inventory at
Tampa, Galveston and Culberson have been materially changed due to FRP's use of
the "Marine Duval", Pennzoil will propose an appropriate adjustment to reflect
the amounts that would have been paid under this Section 2.10 if FRP had not
used the "Marine Duval".  The amount of such adjustment will be negotiated in
good faith by the parties.  If the parties are unable to agree upon the amount
of such adjustment within 60 days of Pennzoil's initial proposal, then the
arbitration procedure outlined in Section 2.11(b) shall be used by the parties
to establish the amount of the adjustment.  Each party will be entitled to make
one proposal, the Panel will be required to choose one of those two proposals
and its decision will be binding on the parties.  Costs of arbitration will also
be allocated in accordance with Section 2.11(b).

          2.11 TAMPA AVERAGE SULPHUR PRICE.  (a)  If, for purposes of
calculating the Tampa Average Sulphur Price, "Green Markets" ceases publication
or no longer publishes the required prices or if the prices published in "Green
Markets" are no longer representative of prevailing contract sulphur prices in
Tampa, FRP and Pennzoil shall agree upon an alternative basis for determining
the Tampa Average Sulphur Price that will be representative of prevailing
contract (rather than spot) sulphur prices in Tampa from time to time.  Such
agreement shall be made following good faith negotiations which shall commence
promptly upon the provision of written notice by either party to the other party
("WRITTEN NOTICE") that an alternative basis is necessary.

          (b)  If the parties are unable to agree on such an alternative basis
within 60 days of the provision of Written Notice, the new basis shall be
finally and conclusively determined by a panel of arbitrators (the "PANEL")
consisting of three members unaffiliated with either party and selected as
hereinafter provided.  Each of Pennzoil and FRP shall select one member of the
Panel within five Business Days after the 60 day period referred to above and
the third member shall be selected by mutual agreement of the two members so
selected within an additional ten Business Days.  If either party does not
appoint its member of the Panel as provided above, then the alternative basis
proposed by the other party Section shall prevail.  Panel members shall be
chosen on the basis of their knowledge of the agricultural minerals industry in
general and the sulphur industry in particular.  The Panel shall meet in New
York, New 


                                       27

<PAGE>

York or such other place as a majority of the members of the Panel determines
more appropriate.  Each party shall provide the Panel within 30 Business Days of
its formation with one or more proposals as to the appropriate alternative basis
for determining the prevailing contract market price for sulphur FOB Tampa
Terminal.  The parties shall be given the opportunity to submit in writing
supporting information or data for their proposals and to each make an oral
presentation to the Panel.  The Panel shall then decide (by a majority) within
45 Business Days of its formation which one of the proposed bases will most
accurately reflect the prevailing contract sulphur price in Tampa.  It is
understood and agreed that the Panel will not have discretion to select any
basis for the Tampa Average Sulphur Price other than one of the bases proposed
by the parties, and will not have authority to modify or amend such proposal. 
The basis adopted by the Panel shall be binding on the parties for future
determinations of the Tampa Average Sulphur Price.  The costs associated with
the arbitration procedure described in this Section 2.11(b), including the fees
and expenses of the arbitrators and the costs reasonably incurred by the parties
themselves in preparing their proposals, shall be borne by the party whose
proposals are not selected by the Panel.
     
          (c)  Until such time as such an alternative basis has been mutually
agreed as described in Section 2.11(a), or determined by the Panel as described
in Section 2.11(b), the Tampa Average Sulphur Price shall be determined
utilizing prices published in "Green Markets" as described in the definition of
"Tampa Average Sulphur Price"; PROVIDED that once an alternative basis has been
agreed upon that new basis shall be applied retroactively to any payments made
with respect to periods after receipt by a party of Written Notice.


                                    ARTICLE 3

                   REPRESENTATIONS AND WARRANTIES OF PENNZOIL

          Pennzoil represents and warrants to FRP as of the date hereof and as
of the Closing Date that:

          3.1  CORPORATE EXISTENCE AND POWER.  Pennzoil is a corporation duly
incorporated, validly existing and in good standing under the laws of its
jurisdiction of incorporation, and 


                                       28

<PAGE>

has all corporate powers and all material governmental licenses, authorizations,
permits, consents and approvals required to carry on its business as now
conducted.  Pennzoil is duly qualified to do business as a foreign corporation
and is in good standing in each jurisdiction where such qualification is
necessary in connection with the conduct of the Business, except for those
jurisdictions where failure to be so qualified would not, individually or in the
aggregate, have a Material Adverse Effect.  Pennzoil has heretofore delivered to
FRP true and complete copies of its certificate of incorporation and bylaws as
currently in effect.

          3.2  CORPORATE AUTHORIZATION.  The execution, delivery and performance
by Pennzoil of this Agreement are within Pennzoil's corporate powers and have
been duly authorized by all necessary corporate action on the part of Pennzoil. 
This Agreement constitutes a valid and binding agreement of Pennzoil,
enforceable against Pennzoil in accordance with its terms, except as enforcement
hereof may be limited by bankruptcy, insolvency, reorganization or other similar
laws affecting enforcement of creditors' rights generally and except as
enforcement hereof is subject to general principles of equity (regardless of
whether such enforcement is considered in a proceeding in equity or at law).

          3.3  GOVERNMENTAL AUTHORIZATION.  The execution, delivery and
performance by Pennzoil of this Agreement require no action by or in respect of,
or filing with, any Governmental Authority other than (i) compliance with any
applicable requirements of the HSR Act; and (ii) compliance with any applicable
requirements of the 1934 Act.

          3.4  NON-CONTRAVENTION.  The execution, delivery and performance by
Pennzoil of this Agreement do not and will not (i) violate the certificate of
incorporation or bylaws of Pennzoil, (ii) assuming compliance with the matters
referred to in Section 3.3, violate any applicable Law, (iii) assuming the
obtaining of all Required Consents, constitute a default under or give rise to
any right of termination, cancellation or acceleration of any right or
obligation relating to the Business or to a loss of any benefit relating to the
Business to which Pennzoil is entitled under (a) any provision of any agreement,
contract or other instrument binding upon Pennzoil or by which any of the
Purchased Assets is or may be bound or (b) any Permit or (iv) result in the 


                                       29

<PAGE>

creation or imposition of any Lien on any Purchased Asset, other than Permitted
Liens.  From August 22, 1994 through the date of this Agreement, Pennzoil has
not taken any action that would have resulted in a breach of any covenant or
agreement contained in this Agreement if this Agreement had been executed on
August 22, 1994.

          3.5  REQUIRED CONSENTS.  SCHEDULE 3.5 sets forth each agreement,
contract or other instrument binding upon Pennzoil or any Permit requiring a
consent or other form of approval as a result of or a waiver of rights to permit
the execution, delivery and performance of this Agreement (each such consent, a
"REQUIRED CONSENT" and together the "REQUIRED CONSENTS").

          3.6  FINANCIAL STATEMENTS.  The unaudited balance sheet for the
Business as of December 31, 1993 and the related unaudited statements of
operations and cash flows for the Business for the year ended December 31, 1993
and the Balance Sheet and the related unaudited interim statement of operations
and cash flows for the six months ended June 30, 1994 (collectively, the
"FINANCIAL STATEMENTS") fairly present, in conformity with generally accepted
accounting principles applied on a consistent basis (except as may be indicated
in the notes thereto), the financial position as of the dates thereof and its
results of operations and cash flows for the periods then ended (subject to
normal year-end adjustments in the case of any unaudited interim financial
statements).

          3.7  ABSENCE OF CERTAIN CHANGES.  Except as reported in monthly
financial and operating reports that are delivered to FRP before the date of
this Agreement, since the Balance Sheet Date, the Business has been conducted in
the ordinary course consistent with past practices, and there has not been:

          (a)  any event, occurrence, development or state of circumstances or
     facts which has had or could reasonably be expected to have a Material
     Adverse Effect other than those that may be deemed to have occurred by
     virtue of general changes in economic conditions or conditions generally
     affecting the sulphur mining and marketing business;

          (b)  any creation or other incurrence of any Lien (other than
     Permitted Liens) on any Purchased Asset;


                                       30

<PAGE>

          (c)  any damage, destruction or other casualty loss (whether or not
     covered by insurance) affecting the Business or any Purchased Asset which,

<PAGE>

          (b)  SCHEDULE 3.8(b) correctly describes the Mineral Interests.

          (c)  To the knowledge of Pennzoil, SCHEDULE 3.8(c) correctly describes
all Personal Property with a book value in excess of $100,000 and any Liens
thereon, specifying in the case of leases or subleases, the name of the lessor
or sublessor, the lease term and basic annual rent.

          (d)  Pennzoil has, and at Closing will have and will convey to FRP,
and upon consummation of the transactions contemplated hereby, FRP will acquire,
Good Title to each of the Purchased Assets. 

          (e)(i)  The real property summarized on SCHEDULE 3.8(a) includes all
Real Property (other than Excluded Assets), and only such real property, as is
used or held for use in connection with the conduct and operations of the
Business as heretofore conducted.  Except for the Other Sulphur Properties and
other Excluded Assets, the mineral interests described on SCHEDULE 3.8(b)
include all Mineral Interests, and only such mineral interests, as are used or
held for use in connection with the conduct and operations of the Business as
heretofore conducted.

            (ii)  All leases of and other instruments and agreements relating to
Real Property, Mineral Interests described on SCHEDULE 3.8(b) or Personal
Property are in good standing and are valid, binding and enforceable in
accordance with their respective terms, and there does not exist under any such
lease, instrument or agreement any material default or any event which with
notice or lapse of time or both would constitute a material default.

           (iii)  Except as provided in SCHEDULE 3.8(e), the plants, buildings,
structures and equipment included in the Purchased Assets and currently used in
the Business are in satisfactory operating condition and repair and have been
reasonably maintained consistent with standards generally followed in the
industry (giving due account to the age and length of use of same, ordinary wear
and tear excepted), are suitable for their present uses and, in the case of
plants, buildings and other structures currently used in the Business (including
without limitation the roofs thereof), are, to the knowledge of Pennzoil,
structurally sound.  Except as expressly 


                                       32

<PAGE>

provided in this Section 3.8(e)(iii), the Personal Property is sold "AS, IS,
WHERE IS," and Pennzoil MAKES NO, AND DISCLAIMS ANY, REPRESENTATION OR WARRANTY,
WHETHER EXPRESS OR IMPLIED, AND WHETHER BY COMMON LAW, STATUTE, OR OTHERWISE, AS
TO (i) MERCHANTABILITY, (ii) FITNESS FOR ANY PARTICULAR PURPOSE, (iii)
CONFORMITY TO MODELS OR SAMPLES OF MATERIALS AND (iv) CONDITION.  FRP EXPRESSLY
WAIVES THE PROVISIONS OF CHAPTER XVII, SUBCHAPTER E, SECTIONS 17.41 THROUGH
17.63, INCLUSIVE (OTHER THAN SECTION 17.555, WHICH IS NOT WAIVED), VERNON'S
TEXAS CODE ANN., BUSINESS AND COMMERCE CODE (THE "DTPA").  Pennzoil and FRP
agree that the preceding disclaimers of warranty are "conspicuous" disclaimers
for purposes of any applicable law, rule or order.  FRP expressly recognizes
that the consideration for which Pennzoil has agreed to sell the Purchased
Assets and perform its obligations under this Agreement has been predicated upon
the inapplicability of the DTPA and this waiver of the DTPA.  FRP further
recognizes that Pennzoil, in determining to proceed with the entering in to of
this Agreement, has expressly relied on this waiver and the inapplicability of
the DTPA.

           (iv)  The plants, buildings and structures included in the Purchased
Assets currently have access to (A) public roads or valid easements over private
streets or private property for such ingress to and egress from all such plants,
buildings and structures and (B) water supply, telephone, gas and electrical
connections, drainage and other utilities, as are necessary for the conduct of
the Business as it is presently conducted.

            (v)  None of the material structures on the Real Property encroaches
upon real property of another person, and no structure of any other person
substantially encroaches upon any Real Property.

          (f)  No Purchased Asset is subject to any Lien, except Permitted
Liens.

          (g)  There are no developments affecting any of the Purchased Assets
pending or, to the knowledge of Pennzoil threatened, which might materially
detract from the value of such Purchased Assets, materially interfere with any
present use of any such Purchased Assets or materially adversely affect the
marketability of such Purchased Assets (other than those developments as may be
deemed to have occurred by virtue of 


                                       33

<PAGE>

business and economic conditions in general and those relating generally to the
sulphur mining and marketing business).

          (h)  Pennzoil has delivered or made available to FRP, true and
complete copies of all records, title policies and reports, leases, contracts
and other materials relating to the Real Property and Mineral Interests.

          (i)  (i)  In this Subsection 3.8(i), "Mineral Interest" refers only to

(Culberson County, Texas) of SCHEDULE 3.8(b).

              (ii)  Each Mineral Interest has been maintained in full force and
effect according to its terms.  Pennzoil has made or caused to be made all
payments, including royalties, delay rentals and shut-in royalties, due under
each Mineral Interest. 

             (iii)  To the knowledge of Pennzoil, no other party to a Mineral
Interest is in breach or default of any obligation under the Mineral Interest.

              (iv)  Except for matters asserted by the General Land Office in
audits of royalty payments to the State of Texas, there has not occurred an
event, fact or circumstance that with the lapse of time or the giving of notice,
or both, would constitute a breach or default of any obligation under a Mineral
Interest by Pennzoil or, to the knowledge of Pennzoil, by any other party to the
Mineral Interest.

              (v)  Neither Pennzoil nor any other party to a Mineral Interest
described on has given or threatened to give notice of any action to terminate,
cancel, rescind or procure a judicial reformation of the Mineral Interest or any
provision of the Mineral Interest.

             (vi)  There are no obligations under a Mineral Interest to engage
in continuous development operations to maintain the Mineral Interest in full
force and effect.

            (vii)  There are no provisions in a Mineral Interest or other
applicable instrument or agreement that increases the royalty share of the
lessor under that Mineral Interest.


                                       34

<PAGE>

           (viii)  Except for matters asserted by the General Land Office in
audits of royalty payments to the State of Texas, no provision in any Mineral
Interest (other than a provision allowing a lessor to take Minerals in kind)

than the basis of the proceeds actually received by Pennzoil from the sale or
other disposition of the Minerals.

             (ix)  Pennzoil is not obligated by (A) any prepayment arrangement,
(B) a "take-or-pay" provision or other similar provision, (C) a production
payment, (D) a minerals "balancing" agreement, or (E) any other arrangements to
deliver Minerals produced from the Mineral Interests described on at some future
time without then or thereafter receiving full payment for the Minerals.

              (x)  Payments for Minerals sold under each Material Contract are
current (subject to adjustment in accordance with the Material Contracts) and in
accordance with the prices set forth in the Material Contracts.

             (xi)  All wells drilled and completed on the Culberson Unit have
been drilled and completed within the boundaries of the applicable Mineral
Interests or within the limits otherwise permitted by contract, by pooling or
unit agreement or by law.

          3.9  SUFFICIENCY OF THE PURCHASED ASSETS.  The Purchased Assets
constitute, and on the Closing Date will constitute, all of the assets or
property (other than Excluded Assets) used or held for use in the Business.

          3.10 NO UNDISCLOSED LIABILITIES.  Other than liabilities disclosed on
SCHEDULE 3.10, there are no liabilities of the Business (other than Excluded
Liabilities) of any kind whatsoever, whether accrued, contingent, absolute,
determined, determinable or otherwise, actual or potential, known or unknown,
and there is no existing condition, situation or set of circumstances which
could reasonably be expected to result in such a liability, and which, in any
such case, could be asserted against FRP or the Purchased Assets other than
liabilities provided for in the Balance Sheet or disclosed in the notes thereto.

contemplated hereby.

required to be disclosed pursuant to this Section 3.12 is a valid and binding
agreement of Pennzoil and is in full force and effect, and neither Pennzoil nor,

binding agreement of FRP, enforceable against FRP in accordance with its terms,
except as enforcement hereof may be limited by bankruptcy, insolvency,
reorganization or other similar laws affecting enforcement of creditors' rights

use their best efforts to cause their respective officers, directors, employees,
accountants, counsel, consultants, advisors and agents to hold, in confidence,
unless compelled to disclose by judicial or administrative process or by other
requirements of law, all confidential documents and information concerning the
Business or FRP furnished to Pennzoil or its Affiliates in connection with the
transactions contemplated by this Agreement, except to the extent that such
information can be shown to have been (i) previously known on a nonconfidential
basis by Pennzoil, (ii) in the public domain through no fault of Pennzoil or
(iii) later lawfully acquired by 


                                       47

<PAGE>

Pennzoil from sources other than FRP; PROVIDED that Pennzoil may disclose such
information to its officers, directors, employees, accountants, counsel,
consultants, advisors and agents in connection with the transactions
contemplated by this Agreement so long as such Persons are informed by Pennzoil
of the confidential nature of such information and are directed by Pennzoil to
treat such information confidentially.  Without limiting the foregoing, Pennzoil
will enter into confidentiality agreements with its officers, directors and
employees pursuant to which such officers, directors and employees will agree to
comply with the foregoing confidentiality obligations.  The obligations in this
Section 5.2 shall continue upon any termination of this Agreement.  If this
Agreement is terminated, Pennzoil and its Affiliates will, and will use their
best efforts to cause their respective officers, directors, employees,
accountants, counsel, consultants, advisors and agents to, destroy or deliver to
FRP, upon request, all documents and other materials, and all copies thereof,
obtained by Pennzoil or its Affiliates or on their behalf from FRP in connection
with this Agreement that are subject to such confidence. 

          5.3  ACCESS TO INFORMATION.  (a)  From the date hereof until the
Closing Date (or, in the case of information relating to Other Sulphur
Properties, until the date six months after the Closing Date), Pennzoil (i) will
give FRP, its counsel, financial advisors, auditors and other authorized
representatives full access during normal business hours to the offices,
properties, books and records of Pennzoil relating to the Business, (ii) will
furnish to FRP, its counsel, financial advisors, auditors and other authorized
representatives such financial, exploration and operating data and other
information relating to the Business as such Persons may reasonably request and
(iii) will instruct the employees, counsel and financial advisors of Pennzoil to
cooperate with FRP in its investigation of the Business; PROVIDED that no
investigation by FRP or other information received by FRP shall operate as a
waiver or otherwise affect any representation, warranty or agreement given or
made by Pennzoil hereunder.  Any investigation pursuant to this Section shall be
conducted in such manner as not to interfere unreasonably with the conduct of
the business of Pennzoil. 

          (b)  From the date hereof until the Closing Date, Pennzoil will
furnish to FRP, (i) within 30 days after the end of each fiscal quarter, the
unaudited interim balance sheet for the 


                                       48

<PAGE>

Business and the related unaudited interim statements of income and cash flows
for the Business for that quarter and (ii) within 45 days after the end of a
fiscal year, the audited balance sheet for the Business and the related audited
statements of income and cash flow for that fiscal year.

          (c)  No later than 45 days after the date of this Agreement, Pennzoil
will cause the balance sheet for the Purchased Assets and Assumed Liabilities as
of December 31, 1993 and the related statement of operations and cash flows for
the twelve months then ended to be audited by its independent public accountants
and will cause such audited statements to be delivered to FRP.  FRP will bear
the reasonable expense of the independent public accountants.

          5.4  NOTICES OF CERTAIN EVENTS.  Pennzoil shall promptly notify FRP
of:

          (i)  any notice or other communication from any Person alleging that
     the consent of such Person is or may be required in connection with the
     transactions contemplated by this Agreement;

         (ii)  any notice or other communication from any Governmental Authority
     in connection with the transactions contemplated by this Agreement;

        (iii)  any actions, suits, claims, investigations or proceedings
     commenced or, to its knowledge threatened against, relating to or involving
     or otherwise affecting Pennzoil or the Business that, if pending on the
     date of this Agreement, would have been required to have been disclosed
     pursuant to Section 3.11 or that relate to the consummation of the
     transactions contemplated by this Agreement; and

         (iv)  the damage or destruction by fire or other casualty of any
     Purchased Asset or part thereof or in the event that any Purchased Asset or
     part thereof becomes the subject of any proceeding or, to the knowledge of
     Pennzoil, threatened proceeding for the taking thereof or any part thereof
     or any right relating thereto by condemnation, eminent domain or other
     similar governmental action.


                                       49

<PAGE>

          5.5  NONCOMPETITION.  (a)  Pennzoil agrees that for a period of five
full years from the Closing Date, neither it nor any of its Affiliates shall
engage, either directly or indirectly, as a principal or for its own account or
solely or jointly with others, or as stockholders in any corporation or joint
stock association, in any business that competes with the Business anywhere in
the Western Hemisphere; PROVIDED that nothing herein shall prohibit (i) the
acquisition by Pennzoil or any of its Affiliates of a business (including any
interest in an oil or natural gas field) which is predominantly engaged in a
business other than the production or marketing of sulphur, (ii) Pennzoil's
conduct of operations at its facilities in Antwerp so long as sales from such
operations are not made in the North American market, (iii) the sale of sulphur
recovered by Pennzoil from the refining of oil and natural gas at facilities
owned by it or any Affiliate and (iv) the conduct of the Business at any time on
or after the date that Pennzoil takes title to the Purchased Assets pursuant to
the exercise of remedies under the Deed of Trust; PROVIDED that, in the case of
Section 5.5(a)(i) or Section 5.5(a)(iii) if more than 20% of the sales of any
business which Pennzoil or its Affiliates owns or proposes to acquire are
attributable to sulphur sales, Pennzoil provides FRP with the opportunity to
negotiate on a good faith basis and on reasonable commercial terms for FRP to
act as Pennzoil's exclusive marketing agent for the sale of any sulphur produced
by the operations of such business.

          (b)  If any provision contained in this Section shall for any reason
be held invalid, illegal or unenforceable in any respect, such invalidity,
illegality or unenforceability shall not affect any other provisions of this
Section, but this Section shall be construed as if such invalid, illegal or
unenforceable provision had never been contained herein.  It is the intention of
the parties that if any of the restrictions or covenants contained herein is
held to cover a geographic area or to be for a length of time which is not
permitted by applicable law, or in any way construed to be too broad or to any
extent invalid, such provision shall not be construed to be null, void and of no
effect, but to the extent such provision would be valid or enforceable under
applicable law, a court of competent jurisdiction shall construe and interpret
or reform this Section to provide for a covenant having the maximum enforceable
geographic area, time period and other provisions (not greater than those
contained herein) as shall be valid and enforceable 


                                       50

<PAGE>

under such applicable law.  Pennzoil acknowledges that FRP would be irreparably
harmed by any breach of this Section and that there would be no adequate remedy
at law or in damages to compensate FRP for any such breach.  Pennzoil agrees
that FRP shall be entitled to injunctive relief requiring specific performance
by Pennzoil of this Section, and Pennzoil consents to the entry thereof.

          5.6  TRADEMARKS; TRADE NAMES. (a)  Except as set forth in the other
subsections of this Section 5.6, after the Closing, FRP and its affiliates shall
not use the name "Pennzoil" or "Duval" or any tradename incorporating the name
"Pennzoil" or "Duval"; PROVIDED that FRP will have full and unrestricted rights
with respect to the "alchemist" symbol used in connection with the Pennzoil
Sulphur Company logo.  The name "Pennzoil" and "Duval" and any tradename
incorporating the name "Pennzoil" or "Duval" shall be referred to, collectively
or individually as the context requires, as the "PENNZOIL TRADE NAMES".

          (b)  After the Closing, FRP shall have the right to sell existing
inventory and to use existing packaging, labelling, containers, supplies,
advertising materials, brochures, technical data sheets and any similar
materials bearing any Pennzoil Trade Name until the earlier of (i) six months
after the Closing Date and (ii) the date existing stocks are exhausted.

          (c)  FRP agrees to discontinue the use of the Pennzoil Trade Name on
buildings, cars, trucks and other fixed assets as soon as practicable after the
Closing and in no event later than six months after the Closing.

          5.7  ENVIRONMENTAL OBLIGATIONS.  In addition to Pennzoil's obligations
under this Agreement as to Environmental Liabilities generally, with respect to
those environmental conditions specifically set forth in this Section 5.7, it is
understood and agreed that:

          (a)  Pennzoil shall be responsible for any and all costs and expenses
     incurred in connection with any investigation, assessment, testing, clean-
     up, remediation, removal, containment, disposal, treatment or monitoring,
     including any costs for capital expenditures associated therewith (the
     "REMEDIAL ACTIVITIES"), in connection with the following:


                                       51

<PAGE>

               (i)  the scrap sulphur located at the Michigan Vent area at the
          Culberson Facility, PROVIDED HOWEVER that Pennzoil shall have no
          environmental obligations if FRP disposes of sulphur materials at such
          area after the Closing Date;

              (ii)  the solid waste landfill located on property owned by the
          State of Texas adjacent to the Culberson Facility;

             (iii)  compliance with any future National Pollutant Discharge
          Elimination System permit limitations on copper in stormwater at the
          Galveston Facility resulting from elevated concentrations of copper in
          existence as of the Closing Date; and

              (iv)  any barium, radium or gross alpha contamination at the Tampa
          Facility. 

     (Sections 5.7(a)(i) to 5.7(a)(iv), the "KNOWN REMEDIAL CONDITIONS").

          (b)  Pennzoil shall be responsible for any and all liabilities
associated with:

          (x)  any stormwater runoff and wastewater within or adjacent to the
     vat sulphur storage area at the Galveston Facility and any sludge that is
     generated through the treatment of such waters (the "GENERATED MATERIALS");
     and 

          (y)  the operation of the vat sulphur storage area and the adjacent
     vat drainage collection and treatment system (the "STORAGE AREA";
     collectively with the Generated Materials, the "GALVESTON ENVIRONMENTAL
     OPERATIONS"); 

arising under the Resource Conservation and Recovery Act as in effect on the
Closing Date (including any rules and regulations promulgated thereunder as of
such date) ("RCRA"), PROVIDED that the parties agree as follows:

          (i)  If the Generated Materials and the Galveston   Environmental
     Operations are in compliance with RCRA, as of the Closing Date, and a
     change in the operation of the Storage Area by FRP after the Closing Date
     as compared with 


                                       52

<PAGE>

     the operation of such area by Pennzoil prior to the Closing Date results in
     noncompliance with RCRA, FRP will be responsible for any liabilities
     associated with such noncompliance.  

          (ii) FRP shall be responsible for payment of operating costs after the
     Closing Date in connection with the Galveston Environmental Operations as
     part of the Assumed Liabilities, PROVIDED that to the extent such costs are
     greater than the historical operating costs of Pennzoil in connection with
     the Galveston Environmental Operations for the two years prior to the date
     hereof, Pennzoil shall be responsible for any such increased amounts.  

          (iii)  If, as of the Closing Date, the Galveston Environmental
     Operations are not in compliance with RCRA and Pennzoil's obligations
     pursuant to this Section 5.7(b) are increased as a result of the operation
     of the Storage Area by FRP after the Closing Date in a manner that is not
     substantially similar to the operation of the Storage Area by Pennzoil
     prior to the Closing Date, FRP shall be responsible for the amount by which
     such obligations have been increased.

          (iv)  FRP shall, within a reasonable time period after the Closing
     Date, conduct a compliance review of the Galveston Environmental
     Operations.  If, after conducting such review, FRP determines that the
     Generated Materials or the Galveston Environmental Operations are not in
     compliance with RCRA, then FRP will consult and cooperate with Pennzoil (in
     coordination with governmental agencies and personnel) in good faith to
     resolve the problem in a mutually satisfactory and cost effective manner
     consistent with prudent business practices.   If, after such consultations,
     FRP reasonably determines that expenditures are necessary in order for the
     Galveston Environmental Operations to be in compliance with RCRA, FRP
     shall, after consultation with Pennzoil and taking into account the cost
     effectiveness of any proposed solution, perform any appropriate measures
     (including without limitation any Remedial Activities and any necessary
     construction or installation of control equipment) to put the Generated
     Materials and the Galveston Environmental Operations into compliance with
     RCRA, and Pennzoil shall reimburse FRP for such expenditures up to a 


                                       53

<PAGE>

     maximum of $2,000,000 promptly upon submission of invoices and any other
     supporting documentation that Pennzoil may reasonably request.  If the
     measures performed by FRP require expenditures in excess of $2,000,000, the
     parties shall split such costs equally and Pennzoil shall reimburse FRP for
     Pennzoil's share promptly upon the submission of the documentation
     identified in the preceding sentence.

          (v)  If the Generated Materials and the Galveston Environmental
     Operations remain in compliance with RCRA three years after completion of
     all appropriate measures, if any are required, in accordance with the
     provisions of Section 5.7(b)(iv), Pennzoil shall have no further liability
     in connection with noncompliance with RCRA at the Galveston Environmental
     Operations.

          (vi) To the extent any fines or penalties are imposed on FRP or its
     Affiliates after the Closing Date in connection with any noncompliance with
     RCRA of the Galveston Environmental Operations at the time of Closing,
     notwithstanding anything herein to the contrary, Pennzoil shall be
     responsible for all such fines or penalties and no such fines or penalties
     shall be included in the cost allocation described in Section 5.7(b)(iv).

          (vii)  As used herein, the term "in compliance with RCRA" means that
     (A) the Generated Materials are not a "hazardous waste" pursuant to RCRA,
     (B) the Galveston Environmental Operations are exempt from RCRA permitting
     requirements, regardless of whether the Generated Materials are a
     "hazardous waste" pursuant to RCRA or (C) the Galveston Environmental
     Operations and the Generated Materials are otherwise in compliance with
     RCRA (including RCRA permitting requirements).
  
          (c)  With respect to Known Remedial Conditions and any other
environmental condition forming the basis for a claim for indemnification
pursuant to Section 11.2(a)(iv), FRP shall notify Pennzoil of the assertion of
any such claim.  Other than in connection with conditions identified in Section
5.7(b), Pennzoil shall have the right to conduct Remedial Activities itself or
reimburse FRP for performing such Remedial Activities and Pennzoil shall provide
FRP with prompt notification of any such decision.


                                       54

<PAGE>

          (d)  If Pennzoil elects to perform any such Remedial Activities,
Pennzoil shall implement such Remedial Activities in a timely fashion and in
accordance with applicable Environmental Laws.  FRP agrees to provide Pennzoil
with access to the facility at which such Remedial Activities are to be
conducted, and shall cooperate with Pennzoil and Pennzoil's agents in the
performance of any such Remedial Activities, PROVIDED that Pennzoil shall not
unreasonably interfere with the operation of FRP's business at such facility and
shall use its best efforts to minimize impairment to the value of FRP's
property.  Pennzoil agrees to (i) prepare any necessary or appropriate remedial
plans and afford FRP a reasonable opportunity to review such plans prior to
their completion and, prior to the finalization of any such plan, consider FRP's
comments and suggestions in good faith, (ii) furnish FRP with copies of any test
results, environmental reports and investigations and correspondence between
Pennzoil and the applicable Governmental Authorities and (iii) indemnify FRP and
its Affiliates against (A) any and all fines or penalties; (B) any damage to
property; and (C) any claims, actions, suits and other proceedings, damages,
liabilities, costs and expenses sought by any third party (whether or not an
agent or employee of Pennzoil), in each case as a result of the activities of
Pennzoil, its agents or its contractors in managing, controlling or implementing
any Remedial Activities.

          (e)  If Pennzoil elects not to perform any such Remedial Activities,
FRP shall perform or cause to be performed such Remedial Activities in a timely
fashion and in accordance with applicable Environmental Laws.  FRP agrees to (i)
prepare any necessary or appropriate remedial plans (taking into account the
cost effectiveness of any proposed remedy or remedial activity) and afford
Pennzoil a reasonable opportunity to review such plans prior to their
completion, and, prior to the finalization of any such plan, consider FRP's
comments and suggestions in good faith and (ii) furnish Pennzoil with copies of
any test results, environmental reports and investigations and correspondence
between FRP and the applicable Governmental Authorities.  Pennzoil shall
reimburse FRP for all reasonable costs and expenses actually incurred by FRP or
its Affiliates in connection with the performance of such Remedial Activities
promptly upon the submission of invoices and any other supporting documentation
that Pennzoil may reasonably request.


                                       55

<PAGE>

          (f)  Notwithstanding anything in this Agreement to the contrary,
Pennzoil shall not be responsible for performing any Remedial Activities or
reimbursing or indemnifying FRP or its Affiliates for any Remedial Activities
unless Pennzoil or FRP or its Affiliates is required to perform such Remedial
Activities (i) pursuant to any Environmental Law or (ii) by any Governmental
Authority (other than Remedial Activities in connection with Section 5.7(b), as
to which this Section 5.7(f) shall not apply). 
          5.8  DAMAGE, DESTRUCTION OR CONDEMNATION.  If prior to the Closing
there occurs any damage to or destruction of any Purchased Asset or part thereof
by fire or other casualty or any taking of any Purchased Asset or part thereof
or right relating thereto by condemnation, eminent domain or other similar
governmental action, Pennzoil and FRP agree, in addition to any other rights
that either party may have under this Agreement, that:

          (a)  all condemnation awards or similar payments relating to any such
     taking and any and all rights thereto shall constitute part of the
     Purchased Assets and shall be transferred to FRP pursuant to this
     Agreement; and

          (b)  subject to the provisions in Section 12.1(d), in the event of any
     such fire or other casualty, Pennzoil shall be obligated at its sole cost
     and expense, (i) and as promptly as reasonably practicable, to repair or
     replace the damaged or destroyed Purchased Assets to restore them to the
     condition they were in prior to the damage or destruction or (ii) if the
     parties agree, which agreement shall not be unreasonably withheld, to
     provide at Closing in immediately available funds an amount sufficient to

will retain Saybolt (or, if Saybolt is not available, another independent
surveyor selected by the parties)  to conduct a survey of the amount of solid
sulphur inventory above the Base Pad Sulphur at the Galveston Facility using
procedures approved by the parties.  The surveyed volume components will be
multiplied by the densities of solid sulphur for each volume component, as are
proposed by the independent surveyor and approved by the parties, to derive the
weight of the solid sulphur.  The sum of the weights of all the component
volumes shall be referred to as the "SOLID SULPHUR AMOUNT".

Solid Sulphur Amount will be marketed on the following terms:

          (i)  On or before the date 90 days after the Closing (the "SOLID
     SULPHUR OPTION DATE"), Pennzoil will have the right to sell any amount of
     solid sulphur up to the Solid Sulphur Amount outside the United States.  On
     or before the Solid Sulphur Option Date, Pennzoil will notify FRP in
     writing as to the proportion of the Solid Sulphur Amount with respect to
     which it has exercised such right, together with the loading schedule for
     such solid sulphur.  Pennzoil will pay FRP $3.50 per ton for loading the
     solid sulphur sold by Pennzoil pursuant to this Section 6.2(b)(i).

          (ii)  During each of the ten Quarterly Periods beginning with the
     first Quarterly Period to commence 90 days after the Solid Sulphur Option
     Date, FRP shall purchase solid sulphur equal to one-tenth of the Solid
     Sulphur Amount that has not been nominated for sale by Pennzoil as provided
     in Section 6.2(a) (the "PURCHASE AMOUNT"), PROVIDED that FRP will have the
     right to increase the amount purchased in any Quarterly Period (A) up to an
     amount equal to two-tenths of the Solid Sulphur Amount under the payment
     conditions set out in Section 6.2(b)(iii) or (B) above an amount equal to
     two-tenths of the Solid Sulphur Amount so long as the parties have agreed
     upon a price for the amount of sulphur which is greater than two-tenths of
     the Solid Sulphur Amount, in either case with the amount of the increase
     above the Purchase Amount for such Quarterly Period being applied to reduce
     equally the Purchase Amount in each of the remaining Quarterly Periods.

          (iii)  On the date 45 days after the end of each of the ten Quarterly
     Periods, FRP will pay to Pennzoil an amount equal to the product of:

               (A)  the greater of (x) the Purchase Amount for such Quarterly
          Period and (y) the amount of solid sulphur that FRP has elected to
          purchase pursuant to Section 6.2(b)(ii) and

               (B)  the Tampa Average Sulphur Price for such Quarterly Period
          less $25.00 (or, in the case of sulphur sold as contemplated by
          Section 6.2(b)(iii)(B), such other price as the parties have agreed). 
          Each payment pursuant to this Section 6.2 shall be made in accordance
          with the requirements of Section 2.7, and subject to payment of
          interest on any late payment calculated as provided therein.

          6.3  PREPAID EXPENSES.  No later than 10 days prior to the Closing
Date, Pennzoil will deliver to FRP a schedule of all prepaid expenses
attributable to the Business.  Prior to the Closing Date, Pennzoil will provide
FRP with such information as it may reasonably request with respect to the items

any issues raised by FRP as to whether the items listed on that schedule will be

<PAGE>

     Pennzoil or its Affiliates to make timely installments or other payments
     required by Code Section 412.

          (e)  No Transferred Employee will become entitled to any retirement,
     severance or similar benefit or enhanced benefit for which FRP could be

          9.3  EMPLOYEES AND OFFERS OF EMPLOYMENT.  (a) At any time on or after
the Closing Date, FRP shall have the right at its sole discretion to offer
employment to any or all active employees of the Business; PROVIDED, that FRP
may terminate at any time after the Closing Date the employment of any employee
who accepts such offer.  FRP agrees to notify Pennzoil as soon as is reasonably
practicable for FRP in light of its business objectives, and in any event within
six months of the Closing Date, of the names of active employees of the Business
to whom FRP intends to offer employment and FRP will offer employment to such
employees within the six-month period.  For purposes of this Article 9, the term
"ACTIVE EMPLOYEE" shall mean any Person who, on the Closing Date, is actively
employed by Pennzoil or who is on short-term disability leave, authorized leave
of absence, military service or lay-off with recall rights as of the Closing

employees employment at any time on or after the date they return to active
employment with Pennzoil), but shall exclude any other inactive or former
employee including any Person who has been on long-term disability leave or
unauthorized leave of absence or who has terminated his or her employment,

EMPLOYEE" and the date on which a Transferred Employee commences employment with
FRP shall be referred to as the "TRANSFER DATE" with respect to such Transferred

HOWEVER, that if during that six-month period Pennzoil desires to solicit any
active employee of the 


                                       66

<PAGE>

not assume responsibility for any Transferred Employee until such employee
commences employment with FRP.  FRP shall have no obligation to offer employment
to any Pennzoil employee.  Subject to any contrary provision in the Transition
Services Agreement, until such time as a Transferred Employee is hired by FRP
and commences employment with FRP, he or she shall remain and shall be
considered as a Pennzoil employee, and FRP will have no obligation to such
employee for statutory or other purposes.

          9.4  PENNZOIL'S EMPLOYEE BENEFIT PLANS.  (a)(i) Subject to Section
9.4(a)(ii), Pennzoil shall retain all obligations and liabilities under the

employee (including any beneficiary thereof) who is not a Transferred Employee. 
Except as expressly set forth herein, Pennzoil shall retain all liabilities and
obligations under the Employee Plans and Benefit Arrangements for each
Transferred Employee in respect of benefits accrued as of the Transfer Date for
the Transferred Employee, and neither FRP nor any of its Affiliates shall have
any liability with respect thereto.  Accrued benefits or account balances of
each Transferred Employee under the Employee Plans and Benefit Arrangements
qualified under Section 401(a) of the Code shall be fully vested as of that
Transferred Employee's Transfer Date.  

        (ii)  FRP shall be responsible to Pennzoil for up to a maximum aggregate
amount of $8 million in severance pay (as provided for under Pennzoil's existing
severance plans), pension and benefit liabilities incurred in connection with
existing severance plans and incentive pay under the 1994 IBITDA plan,
associated with Pennzoil's active employees of the Business and for which
liability is incurred by Pennzoil at any time from the Closing Date until the
later of the date nine months after the Closing Date or the expiration of the
Transition Services Agreement ("PERSONNEL COSTS").  The parties agree that if
FRP terminates any Transferred Employee on or prior to the date nine months
after the Closing, such Transferred Employee will be entitled to the same
severance payment that he would have received from Pennzoil (as provided for
under Pennzoil's existing severance plans) if he had not accepted employment
with FRP, and the amount of such payments shall constitute Personnel Costs for
all purposes of this Agreement.  On the day nine months after the 


                                       67

<PAGE>

Closing Date, FRP shall calculate the cumulative amount of such Personnel Costs.
If the Personnel Costs amount to less than $8 million, FRP shall pay Pennzoil
the Personnel Costs, and in addition, 50 percent of the amount calculated by
subtracting the Personnel Costs from $8 million.  Pennzoil shall be responsible
for any portion of the Personnel Costs that exceeds $8 million, PROVIDED that
Pennzoil will not be responsible for any portion of such excess that results
from stay bonuses (other than those paid at Pennzoil's direction) or other
increases in benefits implemented by FRP after the Closing Date.  Likewise, FRP
shall not be responsible for any increase in benefits implemented by Pennzoil
after the Closing Date.

          (b)  With respect to each Transferred Employee (including any
beneficiary or dependent thereof), Pennzoil shall retain (i) all liabilities and
obligations arising under any group life, accident, medical, dental or
disability plan or similar arrangement (whether or not insured) to the extent
that such liability or obligation relates to contributions or premiums accrued
(whether or not payable), or to claims incurred (whether or not reported), on or
prior to that Transferred Employee's Transfer Date, (ii) all liabilities and
obligations arising under any worker's compensation arrangement to the extent
such liability or obligation relates to the period prior to that Transferred
Employee's Transfer Date, including liability for any retroactive workman's
compensation premiums attributable to such period and all other liabilities
and obligations arising under the Employee Plans and the Benefit
Arrangements to the extent any such liability or obligation relates to the
period prior to that Transferred Employee's Transfer Date, including
proportional accruals through that Transfer Date and including without
limitation liabilities and obligations in respect of accruals through that
Transfer Date under any bonus plan or arrangement, any vacation plans,
arrangements and policies.

          (c)  FRP will recognize Pennzoil service for Transferred Employees for
the purposes of (i) vesting in FRP's 401(k) and pension plans, (ii) vacation
eligibility, (iii) service award eligibility, (iv) wage and salary continuation
and (v) severance benefits.  FRP will not recognize Pennzoil service for
Transferred Employees for purposes of pension accruals and for determining
eligibility for retiree medical, dental or other retiree coverage.

          (d)  Subject to the provisions of Section 9.4(e), after the Transfer
Date, Transferred Employees and their dependents shall be covered under FRP's
medical insurance policies without any exclusions for pre-existing medical
conditions or other retiree coverage.  Co-payments and deductibles of
Transferred Employees under Pennzoil's medical insurance policies shall be
credited against co-payment and deductible requirements under FRP's medical
insurance policies.   

          (e)  With respect to any Transferred Employee (including any
beneficiary or dependent thereof) who enters a hospital or is on short-term
disability under any Benefit Arrangement on or prior to that Transferred
Employee's Transfer Date and continues in a hospital or on short-term disability
after that Transfer Date, Pennzoil shall be responsible for claims and expenses
incurred both before and after that Transfer Date in connection with such
Person, to the extent that such claims and expenses are covered by a Benefit
Arrangement, until such time, (if any) that, in the case of a Transferred
Employee, such Person resumes full-time employment with FRP or one of its
Affiliates and, in the case of any beneficiary or dependent of a Transferred
Employee, such Person's hospitalization has terminated.  With respect to any
Benefit Arrangements covering medical expenses and other costs relating to
pregnancies and maternity leave, Pennzoil shall be responsible for all claims
(whether or not reported) and expenses incurred during the period prior to and
ending on that Transfer Date, and FRP or one of its Affiliates shall be
responsible for such benefit arrangements covering such pregnancies and
maternity leave for the period subsequent to that Transfer Date.

          9.5  CONTINUATION OF CERTAIN ADMINISTRATIVE SERVICES AND INSURANCE
COVERAGE.  The parties agree that Pennzoil will continue certain administrative
services and continue to provide insurance coverage after the Closing Date to
the extent provided in and in accordance with the provisions of the Transition
Services Agreement.

          9.6  WARN ACT.  The parties agree to cooperate in good faith to
determine whether any notification may be required under the WARN Act as a
result of the transactions contemplated by this Agreement.  FRP will be
responsible for providing any notification that may be required under the WARN
Act with respect to any Transferred Employees.  Pennzoil will be responsible for


                                       69

<PAGE>

providing any notification that may be required under the WARN Act with respect
to any employees of the Business that are not Transferred Employees, PROVIDED
that FRP has given sufficient notice to enable Pennzoil to provide such timely
notification.  If FRP fails to provide sufficient notice, FRP shall be liable
for any additional expenditure resulting from the failure to provide
notification required under the WARN Act with respect to any employees of the
Business.

          9.7  NO THIRD PARTY BENEFICIARIES.  No provision of this Article shall
create any third party beneficiary or other rights in any employee or former
employee (including any beneficiary or dependent thereof) of Pennzoil or of any
of its subsidiaries in respect of continued employment (or resumed employment)
with either FRP or the Businesses or any of their Affiliates and no provision of
this Article 9 shall create any such rights in any such Persons in respect of
any benefits that may be provided, directly or indirectly, under any Employee
Plan or Benefit Arrangement or any plan or arrangement which may be established
by FRP or any of its Affiliates.  No provision of this Agreement shall
constitute a limitation on rights to amend, modify or terminate after the
Closing Date any such plans or arrangements of FRP or any of its Affiliates.

                            SURVIVAL; INDEMNIFICATION

          11.1  SURVIVAL.  (a)  The representations and warranties of the
parties hereto contained in this Agreement or in any certificate or other
writing delivered pursuant hereto or in connection herewith shall not be limited
or affected by any investigation undertaken by either party hereto, and shall
survive the Closing until the second anniversary of the Closing Date or (i) in
the case of Sections 3.1, 3.2, 4.1 and 4.2, indefinitely, (ii) in the case of
Section 3.20(a), until the fifth anniversary of the Closing and (iii) in the
case of the representations and warranties relating to Taxes or contained in
Article 9, until expiration of the applicable statutory period of limitations
(giving effect to any waiver, mitigation or extension thereof), if later, and
shall thereafter terminate, together with any associated right of
indemnification pursuant to Section 11.2(a)(i).  Notwithstanding the preceding
sentence any representation or warranty in respect of which indemnity may be
sought under Section 11.2(a)(i) and the associated right of indemnification
under Section 11.2(a)(i), shall survive the time at which it would otherwise
terminate pursuant to the preceding sentence, with respect to any matter
identified in a notice (which notice shall identify the representation or
warranty claimed to have been breached or to have been inaccurate, and shall
state with reasonable particularity the nature of the 


                                       73

<PAGE>

asserted breach or inaccuracy) given prior to such time to the party against
whom such indemnity may be sought.  

          (b)  Except as expressly provided in this Agreement, the covenants and
agreements of the parties hereto contained in this Agreement (including without
limitation the obligation to make Quarterly Installment Payments) or in any
certificate or other writing delivered pursuant hereto or in connection herewith
shall not be limited or affected by any investigation undertaken by either party
hereto, and shall survive indefinitely together with any associated right of
indemnification.  Without limiting the generality of the preceding sentence, the
indemnification obligation of Pennzoil pursuant to Section 11.2 with respect to
Excluded Liabilities (other than Environmental Liabilities) shall survive
indefinitely whether or not the Excluded Liability involves any
misrepresentation or breach of warranty by Pennzoil under Article 3.

          (c)  Except as provided in Section 5.7(b), the indemnification
obligation of Pennzoil for Environmental Liabilities shall survive for five
years after the Closing Date (other than in connection with Known Remedial
Conditions, as to which the indemnification obligation of Pennzoil shall survive
indefinitely and shall include all future changes in Environmental Laws),
PROVIDED that if within such five-year period FRP notifies Pennzoil of the
existence of any Environmental Liability that requires remediation (whether at
the time of notification or at some future date) under Environmental Laws in
effect at the time of such notification, Pennzoil shall indemnify FRP and its
Affiliates for all Losses incurred or suffered by FRP or its Affiliates in
connection with such Environmental Liability and, in accordance with the
provisions of Section 5.7 relating to remediation, Pennzoil shall be responsible
for all Remedial Activities relating to any such Environmental Liability
(including Remedial Activities that might be required due to changes in
Environmental Laws after such five-year period) and such obligations shall
survive indefinitely.

          11.2  INDEMNIFICATION.  (a)  Pennzoil hereby indemnifies FRP and its
Affiliates against and agrees to hold each of them harmless from any and all
damage, loss, liability and expense (including without limitation reasonable
expenses of investigation (including the cost of environmental consultants,
engineers or technical personnel) and reasonable attorneys' fees 


                                       74

<PAGE>

and expenses in connection with any action, suit or proceeding) (collectively,
"LOSS") incurred or suffered by FRP or any of its Affiliates arising out of or
in connection with:

           (i)  any misrepresentation or breach of warranty by Pennzoil under
     this Agreement, PROVIDED, HOWEVER, that Pennzoil shall be liable only if
     the aggregate amount of any such Losses exceeds $500,000 and PROVIDED
     FURTHER that for purposes of making such calculation the representation set
     forth in Section 3.20(a)(iv) shall be read without any materiality
     qualification (the "FRP Retention") and then only to the extent of such
     excess;

          (ii)  any breach of any covenant or agreement made or to be performed
     by Pennzoil pursuant to this Agreement;

         (iii)  the failure of Pennzoil to discharge or perform any Excluded
     Liability; 

          (iv)  subject to and consistent with the provisions of Section 5.7,
     any Environmental Liabilities; or

           (v)  any liability to the State of Texas for royalties owed as a
     result of sulphur production carried out prior to the Closing.

The FRP Retention shall not apply to Losses covered by Subsections 11.2(a)(ii)
through 11.2(a)(v) above whether or not such Losses are also covered by Section
11.2(a)(i).

          (b)  FRP hereby indemnifies Pennzoil and its Affiliates against and
agrees to hold each of them harmless from any and all Loss incurred or suffered
by Pennzoil or any of its Affiliates arising out of or in connection with any
misrepresentation or breach of warranty, covenant or agreement made or to be
performed by FRP pursuant to this Agreement.

          11.3  PROCEDURES.  The party seeking indemnification under Section
11.2 (the "INDEMNIFIED PARTY") agrees to give prompt notice to the party against
whom indemnity is sought (the "INDEMNIFYING PARTY") of the assertion of any
claim, or the commencement of any suit, action or proceeding in respect of which
indemnity may be sought under such Section.  The Indemnifying Party may, and at
the request of the Indemnified 


                                       75

<PAGE>

Party shall, participate in and control the defense of any such suit, action or
proceeding at its own expense.  The Indemnifying Party shall not be liable under
Section 11.2 or for any settlement effected without its consent of any claim,
litigation or proceeding in respect of which indemnity may be sought hereunder. 
In addition, if a claim for indemnification for Environmental Liabilities
involves Remedial Activities, such claim shall be processed in accordance with
the applicable provisions of Section 5.7.


                                   ARTICLE 12

                                   TERMINATION

          12.1  GROUNDS FOR TERMINATION.  This Agreement may be terminated at
any time prior to the Closing:

          (a)  by mutual written agreement of Pennzoil and FRP;

          (b)  by either Pennzoil or FRP if the Closing shall not have been
     consummated on or before December 31, 1995;

          (c)  by either Pennzoil or FRP if there shall be any Law that makes
     the consummation of the transactions contemplated hereby illegal or
     otherwise prohibited or if consummation of the transactions contemplated
     hereby would violate any nonappealable final order, decree or judgment of
     any Governmental Authority having competent jurisdiction; or

          (d)  by either Pennzoil or FRP if there shall occur any damage to or
     destruction of any Purchased Asset or part thereof by fire or other
     casualty if, in any such case, the cost of repair or replacement of the
     damaged or destroyed Purchased Assets (net, in the case of Pennzoil, of the
     estimated insurance proceeds related thereto) exceeds $2,000,000; PROVIDED,
     HOWEVER, that Pennzoil may not terminate this Agreement pursuant to this
     Section 12.1(d) if FRP waives Pennzoil's obligations pursuant to Section
     5.8(b) in connection with the event of destruction of or damage to any
     Purchased Assets.


                                       76

<PAGE>

          The party desiring to terminate this Agreement pursuant to SECTIONS
12.1(b), 12.1(c) OR 12.1(d) shall give notice of such termination to the other
party.

          12.2  EFFECT OF TERMINATION.  If this Agreement is terminated as
permitted by Section 12.1, such termination shall be without liability of either
party (or any stockholder, director, officer, employee, agent, consultant or
representative of such party) to the other party to this Agreement; PROVIDED
that if such termination shall result from the willful failure of either party
to fulfill a condition to the performance of the obligations of the other party,
failure to perform a covenant of this Agreement or breach by either party to
this Agreement of any representation or warranty or agreement contained herein,
such party shall be fully liable for any and all Losses incurred or suffered by
the other party as a result of such failure or breach.  The provisions of
Sections 5.2, 6.1 and 13.3 shall survive any termination hereof pursuant to
Section 12.1.

                               ASSET PURCHASE AGREEMENT


    AMENDMENT NO. 1 dated as of January 3, 1995 to the Asset Purchase Agreement
(the "Agreement") dated as of October 22, 1994 between Freeport-McMoRan Resource
Partners Limited Partnership, a Delaware limited partnership ("FPR") and

                                W T I N E S S E T H :

    WHEREAS, FRP and Pennzoil desire to amend the Agreement as set forth in
this Amendment No. 1;

    NOW, THEREFORE, the parties hereto agree as follows:

    1.   DEFINITIONS.  Unless otherwise specifically defined herein, each 
term used herein which is defined in the Agreement shall have the meaning 
assigned to such term in the Agreement.  Each reference to "hereof," 
"hereunder," "herein" and "hereby" and each reference to "this Agreement" and 
each other similar reference contained in the Agreement shall refer to the 
agreement as amended by this Amendment No. 1.

    2.   ACCOUNTING ADJUSTMENT.  The parties have agreed, as an accounting 
convenience, to establish a financial accounting cut-off time (the 
"Accounting Cut-Off") for the transaction of 12.:01 a.m. on January 1, 1995.  
Accordingly, upon the occurrence of the Closing, the parties will make all 
appropriate financial and accounting adjustments (including appropriate 
payments to each other and to third parties) as if the Closing had occurred 
at the Accounting Cut-Off.  In particular, FRP will be entitled to record and 
receive (and receive the benefit of) all operating revenues, inventories, 
receivables and prepaid expenses generated from or with respect to the 
Purchased Assets from and after the Accounting Cut-Off and shall record and 
pay all payables and contract obligations incurred in connection with the 
Purchased Assets (and all obligations of FRP to reimburse Pennzoil for 
royalties as provided in the Agreement shall commence) from and after the 
Accounting Cut-Off.  Pennzoil's cash and cash equivalents on hand and in 
banks as of the Accounting Cut-Off (except for Petty Cash as of that time) 
and all accounts, notes and other receivables attributable to the operation 
of the Business prior to the Accounting Cut-Off shall continue to be Excluded 
Assets, but all such items generated on or after the Accounting Cut-Off shall 
be Purchased Assets. Similarly, all accounts payable attributable to the 
operation of the Business prior to the Accounting Cut-Off shall continue to 
be Excluded Liabilities, but all accounts payable attributable to the 
operation of the Business on or after the Accounting Cut-Off shall be Assumed 
Liabilities.  The liquid sulphur inventory adjustment contemplated by 

<PAGE>


Section 2.10 of the Agreement shall be conducted as of the Accounting 
Cut-Off, and sales of liquid sulphur inventory (or other inventory 
constituting Purchased Assets) on or after the Accounting Cut-Off shall be 
for the account and benefit of FRP.  The prepaid expense adjustment 
contemplated by Section 6.3 of the Agreement shall be made in respect of 
prepaid expenses as they exist at the Accounting Cut-Off.  The proration 
provisions set forth in Sections 7.4 and 8.3 of the Agreement shall be made 
as of the Accounting Cut-Off rather than as of the Closing Date.  The first 
Quarterly Period shall commence on January 1, 1995, and the last Quarterly 
Period shall end on the earlier of December 31, 2014 and the date specified 
in clause (v) of the definition of Quarterly Period.  The term "Option Date" 
shall mean January 1, 1999 and each subsequent third anniversary of the First 
Option Date.  For all other purposes of the Agreement, including without 
limitation, determining the Purchased and Excluded Assets and the Assumed and 
Excluded Liabilities, compliance with the representations and covenants set 
forth in the Agreement, responsibility for damage, destruction or 
condemnation of the assets and satisfaction of the conditions to Closing, the 
references in the Agreement to the Closing Date shall mean the actual date of 
the Closing.

    3.   VALUATION OF PURCHASE ASSETS IN FLORIDA.  The parties agree that for
tax purposes, the portion of the Purchase Price attributable to all Purchased
Assets located in the State of Florida shall be deemed to be $966,500.

    4.   GAS SUPPLY.  Section 2.2(h) of the Agreement is hereby deleted in its
entirety, and it is understood that Pennzoil's gas contract with Texaco Inc.
shall be deemed to be added to Schedule 3.12(a) of the Agreement and shall be a
"Contract" to be assigned by Pennzoil to FRP at the Closing.  Section 5.9 of the
Agreement is hereby deleted in its entirety.

    5.   SOLID SULPHUR AMOUNT.  Section 6.2(a) of the Agreement is hereby
amended and restated to read in its entirety:

              "6.2 MARKETING SOLID SULPHUR.  (a) The parties will
         retain an independent surveyor acceptable to all of the
         parties to conduct a survey of the amount of solid sulphur
         inventory above the Base Pad Sulphur at the Galveston
         Facility using procedures approved by the parties, such
         survey to be completed within 90 days of the Closing.  The
         surveyed volume components will be multiplied by the
         densities of solid sulphur for each volume component, as are
         proposed by the independent surveyor and approved by the
         parties, to derive the weight of the solid sulphur.  The sum
         of the weights of all of the component volumes shall be
         referred to as the "Solid Sulphur Amount."

    FRP and IMC shall collectively, supply 100% of Partnership's sulphur
requirements during the Contract Term with the quantity to be supplied by each
of FRP and IMC being determined as set forth in subparagraphs (a) through (d)
below of this Article IV, unless otherwise agreed by each of Partnership, FRP

as prescribed it subparagraphs (a) through (d) below of this Article IV between
the categories "Base Sulphur" [Confidential*] and "Supplemental Sulphur." 
Schedule A attached hereto and made a part hereof represents the agreement of
the parties hereto as to the manner in which quantities of sulphur to be
supplied by FRP and IMC would be allocated among Partnership plants shown on
such schedule, as well as the allocation of such quantities as between Base
Sulphur and Supplemental Sulphur, in the event Partnership's requirement for
sulphur for a year should be exactly 3,025,000 tons. Schedule B attached hereto
and made a part hereof is a sulphur allocation worksheet which incorporates the
allocation ratios of Schedule A, as supplemented and modified by subparagraphs
(a) through (d) below of this Article IV, and as such constitutes the mechanism
by which quantities to be supplied hereunder to Partnership plants shown on
Schedule A hereof, and the allocation of such quantities for purposes of the
pricing provisions hereof, shall be calculated.

<PAGE>


    (a)  FRP will supply 100% of the requirements of the Faustina, Uncle Sam
         and South Pierce plants, with the allocation of Base Sulphur and
         Supplemental Sulphur to each of such plants to be calculated by the
         use of the Sulphur Allocation Worksheet set forth on Schedule B.

    (b)  All sulphur requirements for the New Wales plant will be supplied by
         FRP and IMC with the portion of such requirements to be supplied by
         each of FRP and IMC for the New Wales plant, and the allocation of
         each such portion as between Base Sulphur and Supplemental Sulphur, to
         be determined by the use of the Sulphur Allocation Worksheet set forth
         on Schedule B, except if at any time IMC has insufficient IMC Main
         Pass Sulphur to meet IMC's Base Sulphur supply obligation at such time
         as determined from Schedule B, it shall so notify FRP and the number
         of tons of IMC Main Pass Sulphur required to meet such obligation (the
         Shortfall) may be supplied by FRP at FRP's election, provided notice
         of FRP's election to supply is furnished to IMC within 30 days of
         FRP's receipt of IMC's notice of the Shortfall. Should FRP decline or
         fail to elect to supply the Shortfall, the Shortfall shall be supplied
         by IMC. In the event of a Shortfall the tonnage supplied by either FRP
         or IMC, as the case may be, to make up the Shortfall shall be deemed
         to be Supplemental Sulphur.

    c)   Notwithstanding subparagraphs (a) and (b) above of this Article IV it
         is intended that

         (i)       if the total sulphur consumed by all of Partnership's then
                   operating plants (excluding the Nichols plant) during any
                   calendar year is 1,275,000 tons (the "Base Tonnage"), then 
                   FRP shall supply 775,000 tons and IMC shall supply 500,000 
                   tons and all such tonnage shall be Base Sulphur (except as 
                   provided otherwise in subparagraph (b) above of this 
                   Article IV in respect of any Shortfall),

         (ii)      if the total sulphur consumed by all of Partnership's then
                   operating plants (excluding the Nichols plant) during any
                   calendar year is less than the Base Tonnage, then FRP shall
                   supply 60.78% of such total and IMC shall supply 39.22% of 
                   such total and all such sulphur shall be deemed to be Base 
                   Sulphur, and

         (iii)     if the total sulphur consumed by all of Partnership's then
                   operating plants (excluding the Nichols plant) during any
                   calendar year is greater then the Base Tonnage (with tonnage
                   in excess of the Base Tonnage being hereinafter referred to
                   as "Supplemental Tonnage"), then FRP shall supply 64.52% of
                   such Supplemental Tonnage and IMC shall supply 35.48% of
                   such Supplemental Tonnage, except that if in such year the
                   quantity of IMC Main Pass Sulphur available for sale exceeds
                   500,000 tons, IMC shall deliver such excess IMC Main Pass
                   Sulphur to Partnership and the quantity of Supplemental
                   Tonnage shall be reduced by the quantity of such excess IMC
                   Main Pass Sulphur so delivered. All Supplemental Tonnage and
                   all such excess IMC Main Pass Sulphur shall be deemed to be
                   Supplemental Sulphur.

    (d)  All sulphur requirements of the Nichols plant will be supplied by FRP
         and IMC in equal quantities and all such sulphur supplied to such
         plant shall be deemed to be Supplemental Sulphur.

<PAGE>


calculated because no sulphur properly includible in such calculation has 
been purchased by IMC and delivered during such month, then, in either such 
event, the parties shall have the rights and obligations hereinafter net 
forth in this Article V.

    5.4.1     At the end of any six-month period described in subclause (i) of
              Section 5.4 above, FRP, IMC or Partnership may by written notice
              to the other parties given within 5 days after the end of such
              period request redetermination of the price payable for sulphur
              delivered hereunder during such period. Not later than five days
              after the end of any month described in subclause (ii) of Section
              5.4 above IMC shall confirm by written notice to FRP the absence
              of a basis for calculating the [Confidential*] for such month and
              the parties shall proceed pursuant to Section 5.4.2 below to
              [Confidential*] sulphur delivered hereunder during such month.
              Sulphur delivered during a month for which a price is unavailable
              pending a price redetermination pursuant to this Article V, shall
              be invoiced and paid for at the price which would have been
              applicable to such sulphur if delivered in the most recent prior
              month for which the [Confidential*].  With respect to any final
              price redetermination made during a month, any billing
              adjustments required to be made by FRP or IMC as the result
              thereof shall be accomplished in the billing party's next monthly
              invoice.

    5.4.2     In the event a notice of either kind contemplated by Section
              5.4.1 is given, FRP, IMC and Partnership shall have a period of
              10 days after the day such notice is given in which to commence
              redetermination of and agree upon the price payable for sulphur
              delivered hereunder during the period to which the notice is
              applicable. In the event the parties are unable to agree upon a
              redetermined price by the end of such 10 day period, the price
              shall be determined through a proceeding for resolution of
              disputes submitted to Endispute Incorporated ("Endispute") in San
              Francisco, California, with the party whose position is upheld by
              Endispute in such proceeding being entitled to recover its
              reasonable attorneys' fees and expenses from the other party. If
              at the time the dispute occurs Endispute is not in the business
              of resolving disputes in San Francisco, California, either party
              may ask the Chief Judge of the United States Court of Appeals for
              the Ninth Circuit to select a similar firm located in San
              Francisco, California. The determination of Endispute or such
              similar firm shall be final and binding on the parties.

    5.4.3     Unless otherwise agreed by the parties in any particular
              instance, a proceeding for dispute resolution under Section 5.4.2
              shall be based on a "baseball arbitration" pursuant to which each
              party shall produce a written statement setting forth the price
              it believes to be the [Confidential*] located in central Florida
              for the time period in issue. The dispute shall be resolved by
              adoption of one of such prices submitted by the parties and not
              at a third price.

                                VI.  SCHEDULING

    6.1  GENERAL; PLANT ACCESS. Partnership shall cooperate in good faith with
each of FRP and IMC for the purpose of obtaining information required for
scheduling sulphur supply logistics, including a rights in each of FRP and IMC
to enter upon the premises of any Partnership plant when such entry is
reasonably required to obtain such information and subject to the prior consent
of Partnership (which consent shall not be unreasonably withheld). Required
information would include, but not be limited to, plant sulphur inventory levels
in tanks and railcars, mechanical condition of transportation equipment, and
sulphur logistic limitations, e.g., dock outage, sulphur pit repairs.
Partnership shall also permit access to Partnership plants from time to time by
FRP and/or IMC contractors as may be reasonably required for purposes of
conducting repairs on transportation equipment, provided reasonable advance
notice is given and provided the conduct of such repairs would not unreasonably
interfere with plant operations.

    6.2  DAILY REPORT. On any day or from day to day as either FRP or IMC
should request, Partnership shall provide to the requesting party, by telecopy
and for each Partnership plant, a report setting forth all deliveries of sulphur
made by each of FRP and IMC to such plant during the preceding day, as well as
the number of tons of sulphur consumed at such plant during such preceding day.

    6.3  OPERATING FORECASTS. Partnership shall provide to each of FRP and IMC,
as and when FRP and/or IMC shall request from time to time during the Contract
Term, a timely forecast of sulphur consumption by plant using the 

<PAGE>


Sulphur Allocation Worksheet attached hereto as Schedule B and of expected 
delivered prices, as well as periodic updates revising such forecast as 
needed for purposes of budgeting and providing uninterrupted sulphur supply.

    6.4  MONTHLY DELIVERY BALANCING. For purposes of maintaining a balance
between the quantities of sulphur each of FRP and IMC are entitled to deliver
hereunder to a Partnership plant and their respective actual deliveries thereto,
Partnership shall, in addition to any other consumption forecasts which
Partnership may be requested to provide under Section 6.3 hereof and by use of
the Sulphur Allocation Worksheet attached as Schedule B hereto, provide to each
of FRP and IMC not later than 30 days prior to the beginning of each calendar
month, or any other period of time as may be mutually agreed upon, a forecast
allocation of the quantities of sulphur to be delivered by each of FRP and IMC
during such month, to each of Partnership plants. Within 5 business days after
the end of such month, Partnership shall utilize such worksheet to determine the
actual allocation of such quantities for such month. Should it appear from the
actual allocation that FRP or IMC, as the case may be, delivered during such
month to a particular Partnership plant a quantity of sulphur greater than the
quantity it was entitled to deliver to such plant during such month, the
quantity in excess of such entitled quantity shall be referred to as an
"over-delivery".  Within such 5-day period, Partnership shall provide to each of
FRP and IMC an amended allocation forecast for the then current calendar month
which reflects, for each Partnership plant to which an over-delivery was made
during the preceding calendar month a reduction in the tonnage to be delivered
during such current month to such plant by the over-delivering party and a
corresponding increase in the tonnage to be delivered during such current month
to such plant by the under-delivering party.

                                   VII.  DELIVERIES

    7.1  DELIVERIES:  GENERAL. Partnership's written orders specifying the
tonnage of sulphur which Partnership shall wish to take from each of FRP and IMC
during each month shall be placed with FRP and IMC, respectively, within the
first ten days of the month preceding the month in which deliveries are desired.
Deliveries shall be made and taken at a reasonably uniform rate during the
Contract Term. All shipments of sulphur hereunder will be made on commercial
bills of lading. There is reserved to each of FRP and IMC the right to route
shipments of and to select the carriers for the sulphur to be shipped by each
hereunder. All shipments of sulphur hereunder shall be on [Confidential*], with
the shipping party (FRP or IMC,  as applicable) responsible for [Confidential*]
on the sulphur shipped by it from point of origin to such plant; EXCEPT THAT in
the case of sulphur designated by FRP or IMC (as applicable) for delivery to
Partnership at a marine sulphur terminal located in the Port of Tampa, Florida,
Partnership shall provide the trucks required to take delivery of such sulphur
at such terminal and transport same to the Partnership plant for which such
sulphur in destined and all costs of providing such trucks and transporting such
sulphur from such terminal to such plant shall be paid by [Confidential*].

    7.2  FACILITIES.  Partnership will provide, maintain, and make available
facilities, at Partnership plants for unloading rail cars, trucks and barges, as
applicable, delivering sulphur pursuant to this Agreement including but not
limited to rail track to receive railcars and to steam railcars, necessary
transfer lines, pumps, storage tanks, and any other necessary or related
facilities. Such unloading shall be accomplished promptly and any demurrage
and/or detention charges which become due shall be paid by Partnership, unless
the delay is directly attributable to FRP or IMC.

    Partnership will provide, maintain and make available a safe berth for
FRP's barges at each of the Uncle Sam plant and the Faustina plant. Each such
safe berth will provide adequate unloading facilities to accommodate a towboat
and a two barge tow.

    7.3  DAMAGE TO TRANSPORTATION EQUIPMENT. Partnership agrees to (i)
compensate each of FRP and IMC for loss or damage, excepting sulphur corrosion
and ordinary wear and tear, to the property of each and (ii) indemnify and save
each of FRP and IMC harmless from any damage to property other than the property
of each and from any injuries to persons relating in any way to the use of such
railcar(s), trucks(s) and barge(s) which is due to the fault or negligence of
Partnership. Partnership further agrees to promptly report to each of FRP and
IMC, as appropriate, any damage which may be sustained by the railcars(s),
truck(s) or barge(s).

    FRP and IMC agree to (i) compensate Partnership for loss or damage,
excepting ordinary wear and tear, to the property of Partnership and (ii)
indemnify and save Partnership harmless from any loss or damage to property
other than the property of Partnership and from any injuries to persons related
in any way to the use of such railcar(s), truck(s) and barge(s) which is due to
the fault or negligence of either FRP or IMC or their agents or employees.

<PAGE>


    7.4  UNLOADING; DEMURRAGE.

         BARGE - Barge deliveries shall be made by FRP into Partnership's
shorelines at the Uncle Sam and Faustina plants. The sulphur shall be deemed to
have been delivered as it is progressively discharged into such shorelines.
Partnership shall use reasonable efforts to accept multi-barge deliveries:  In
no event shall the number of deliveries by barge to the Uncle Sam and Faustina
plants obliged to be made by FRP during a month exceed a combined total of 25
such deliveries, nor shall FRP be obligated to make barge deliveries in lots
less than approximately 4,000 tons.

    Partnership shall provide, [Confidential*] proper dock facilities where
FRP's barges can moor, together with such flexible connections, shorelines and
other facilities as may be needed to connect such lines with the discharge lines
on FRP's barges and to receive discharge from the barges at a rate of not less
than 500 tons per hour. Partnership shall also provide, without cost to FRP,
such shore labor and facilities as may be needed for the prompt and proper
handling of mooring lines, the making and breaking of shore connections and the
handling of sulphur into and through Partnership's shorelines. Discharge of the
sulphur shall commence promptly following berthing of the barges, and shall
continue with all reasonable dispatch and without interruption, including
nights, Saturdays, Sundays, and holidays. The parties agree to cooperate in
scheduling the arrival of barges and the use of Partnership's docks to the end
that an open berth will be provided for FRP's barges upon their arrival.

    If at any time during the Contract Term a barge is presented at the Uncle
Sam plant or the Faustina plant for unloading and Partnership is unable at such
plant to receive any and/or all of the sulphur available for unloading from such
barge at such time, then, unless such inability, is the fault of the employees
and/or equipment of FRP or its agents, Partnership shall be responsible for
payment of any freight or other associated costs incurred by FRP in redirecting
or diverting the barge in order to discharge therefrom the sulphur which
Partnership was unable to receive as aforesaid.  In the event delays are
experienced in the unloading of sulphur from FRP' barges into shorelines at
either of the Uncle Sam or Faustina plants, regardless of the cause of such
delay except fault of the employees or equipment of FRP or its agents or force
majeure, Partnership shall for each barge so delayed pay FRP Barge Demurrage for
each hour and any fraction of an hour by which actual laytime for unloading
FRP's barges exceeds twelve hours for a single barge tow or twenty-four hours
for a two barge tow; such Barge Demurrage to be an hourly rate reflecting the
full operating cost of the towboat and barge (or towboat and barges, as the case
may be) during the period of time with respect to which the Barge Demurrage is
chargeable. Laytime for unloading shall commence when the barge is tendered to
the plant, berth or no berth, day or night, including Saturday, Sunday and
holidays. Laytime shall end when all shore connections have been disconnected
and removed from FRP's barge, or when notice is given that Partnership is unable
to load the barge.

    TRUCKS - Partnership will provide and maintain a daily tank truck unloading
capability at each of the Partnership plants equal to the average number of tank
trucks unloaded per day at such plant during the period of one year immediately
preceding the date of this Agreement. Necessary personnel and safety equipment
will be provided to accommodate the unloading of tank trucks 7 days a week,
including holidays, 365 days per year. Tank trucks will be unloaded on a "first
come-first served" basis. Any truck detention or demurrage charges incurred by
FRP or IMC at a Partnership plant shall be reimbursed to the incurring party at
cost by Partnership unless such charges were imposed through the fault of the
incurring party.

    RAILCARS - Partnership will unload railcars promptly at destination and
return them to the carrier in accordance with the routing instructions of FRP or
IMC, as applicable. Partnership will not divert any rail car from the
destination to which it was originally consigned by FRP or IMC without prior
notification to and approval by such consigning party (followed by written
confirmation of such approval). FRP and IMC will use best efforts to supply
railcars in good working order.  Should a railcar require minor repair,
Partnership will provide available trackage for repair crews as long as in
Partnership's judgment it does not interfere with plant operations.  Should a
railcar require repairs that cannot be accomplished in the plants, notification
will be given to FRP or IMC, as applicable for railcar disposition. Partnership
shall not be responsible for railcar repairs. FRP or IMC, as applicable, agree
to indemnify and hold harmless Partnership from any and all liability arising
out of or in any way related to the trackage provided for railcar repair,
railcar repair services or the presence of railcars awaiting repair as well as
instructions for dispatch after repair. Said liability and indemnification shall
include but not be limited to injury, sickness, death or property damage.

<PAGE>


    Partnership will provide and maintain a daily railcar unloading capability
at each Partnership plant equal to the average number of railcars unloaded per
day at such plant during the period of one year immediately preceding the date
of this Agreement.

    Unloading of railcars will be performed 7 days a week, 365 days per year,
including holidays. Railcars will be unloaded in the order of their arrival.

    Partnership will have a maximum of 5 free days unloading time starting at
7:00 a.m. on the morning following the time of the railroad's notification to
Partnership of the railcar's constructive placement and ending with official
notice to the railroad of release of the railcar as empty. After such 5 free
days Railcar Demurrage will be assessed against and paid by Partnership per day
or fraction of a day, per railcar, at a rate reflecting the actual cost incurred
by FRP or IMC, as applicable, as the result of the railcar being held by the
Partnership for a period longer than the allowed free time. FRP and IMC shall
each have the right, exercisable on December 31 of each year during the Contract
Term by notice to Partnership given on or before such date, to decrease the
number of free days then being allowed hereunder for unloading at a particular
Partnership plant to the lowest number of free days then being allowed pursuant
to its published tariffs of any railroad carrier for unloading of cars at such
plant (provided that such lowest number of free days is less than 5 free days).

                         VIII.  WEIGHTS AND MEASURED

    The quantity of sulphur delivered by each of FRP and IMC to Partnership
shall be determined based upon a certified bill of lading.  The quantity
determination made by such delivering party will govern (except in case of
proven error) when the delivery is by truck or barge.

    Railcar quantities shall be determined as follows:

    The quantity placed on the bill of lading will be determined by certified
    rail scales at point of railcar loading. In the event rail scales are
    unavailable at origin, the railcar will be weighted in transit to
    destination on railroad certified scales.  In the event the quantity was
    not determined at railcar loading or in transit to the destination, the
    railcar will be weighed upon arrival at destination on certified rail
    scales.  If the railcar was not previously weighed prior to reaching
    destination and should rail scales be unavailable or incapacitated at
    destination, the quantity will be determined by tank car outage tables
    provided by the tank car owner or lessee for that particular railcar,
    taking into consideration correction factors for temperature.

    Barge quantities shall be determined by volumetric measurements of shore
tank(s) prior to, and at the conclusion of, loading appropriately adjusted to
changes in density resulting from varying temperatures and carbonaceous
impurities. Partnership shall have the right to be represented, at Partnership's
expense, during any barge loading.

                            IX.  QUALITY AND FORM

    9.1  SPECIFICATIONS.  Except as otherwise provided in Sections 9.2 and 9.3
below the sulphur to be purchased and sold hereunder shall meet the following
specifications:

         Crude sulphur guaranteed 99.50% pure on a dry basis which shall be
commercially free of arsenic, selenium, and tellurium and which shall contain
not more than 0.25% carbon, not more than 50 parts per million (ppm) ash, and
not more than 10 ppm acidity:  if over 99.50% purity, no charges shall be made
for the excess; if under, a pro-rata allowance shall be made or, at
Partnership's option, acceptance of delivery thereof may be refused by
Partnership (provided that such refusal shall not relieve the selling party (FRP
or IMC, as applicable) of its obligation to replace the quantity so refused with
an equal quantity of sulphur conforming to the specifications set forth in this
Article IX). The sulphur shall be in liquid (molten) form of not less than 260
degrees Fahrenheit when loaded into Partnership receiving facilities.

    9.2  AMENDMENT OF SPECIFICATIONS.  At any time or from time to time during
the Contract Term as a material change should occur in the quality
specifications which are usual and customary in sulphur supply agreements in
effect at the time between sulphur suppliers in general and their customers, the
parties hereto shall confer in good faith and amend this Agreement to accord
with such changed specifications.

    9.3  UNCLE SAM PLANT EXCEPTION.  The specifications set forth in Section
9.1 above shall apply to all sulphur delivered hereunder to the Uncle Sam plant
except that such sulphur shall contain not more carbon than would raise the
calculated percentage of carbon in a storage tank at the Uncle Sam plant to a
level greater than 0.4%.

                              X.  TITLE AND RISK

    Title to sulphur sold hereunder and risk of loss with respect thereto shall
pass to Partnership upon delivery.

                          XI.  INVOICING AND PAYMENT

    11.1 GENERAL.  Within 5 days following the close of each calendar month,
Partnership shall furnish each of FRP and IMC a report setting forth the
quantities of sulphur delivered by each of FRP and IMC to each of Partnership
plants during the preceding month. On the basis of such report FRP and IMC shall
each invoice Partnership within 7 days following the close of each calendar
month for the quantities of sulphur delivered by each of them respectively to
each of Partnership plants during the preceding month. Within fifteen days from
the date of FRP's or IMC's invoice, Partnership shall make payment for the
sulphur so invoiced by electronic transfer of same-day funds. Partnership agrees
to pay FRP, or IMC, as the case may be, a service charge equal to .050% per day
(approximately 1-1/2% per month) on all payments due by Partnership not received
into FRP's or IMC's account, as the case may be, on or before the due date. For
invoicing purposes hereunder, the first quantities of sulphur delivered by FRP
and IMC hereunder to a Partnership plant during any month shall be deemed to be
in fulfillment of the quantity of Base Sulphur which the delivering party is
entitled to deliver to such plant during such month. Notwithstanding the
preceding sentence, with respect to the quantity of Base Sulphur delivered by
FRP during any calendar year, FRP shall endeavor, to the extent Partnership
plant consumption rates permit, to invoice Partnership for such annual quantity
in such manner as will permit such annual quantity to be distributed in
approximately equal portions over the twelve monthly invoices applicable to
deliveries made in such year.

    11.2 FREIGHT REIMBURSEMENT. The monthly report of deliveries to be
furnished each of FRP and IMC pursuant to Section 11.1 above shall also contain
a per ton [Confidential*] (as more fully described hereinafter in this Section
11.2) applicable to the month covered in the monthly report. FRP and IMC shall
in their respective invoices for sulphur delivered during the month covered by
the report, [Confidential*] applicable to that month times the number of tons of
the invoicing party's sulphur delivered to Partnership at a marine sulphur
terminal(s) located in the Port of Tampa, Florida during such month.

    The [Confidential*] for any month shall be [Confidential*] of transporting
sulphur from marine sulphur terminals located in the Port of Tampa, Florida to
Partnership plants in Florida during such month. Such [Confidential*] shall also
be used for purposes of calculating the terminable-to-plant truck delivery costs
contemplated by the definition 

<PAGE>


of "Delivered Price Per Ton" set forth at Section 1.08 hereinabove. In 
calculating such [Confidential*]; (i) the per-ton cost of a truck movement 
from terminal to plant with no [Confidential*] shall be the total cost of 
such [Confidential*] in such movement, and (ii) the per- ton cost of a truck 
movement from terminal to plant, with a [Confidential*] of another commodity 
from the plant for Partnership's account, shall be determined by 
[Confidential*].

    11.3 ANNUAL ASSESSMENT OF [Confidential*] PERIOD. An annual price
adjustment calculation shall be made hereunder by each of FRP and IMC within 30
days after the end of each calendar year to compare the invoiced amount for
sulphur delivered hereunder during such year against the amount which would have
been payable for such sulphur had the [Confidential*] and the [Confidential*]
each been computed on a quarterly, as opposed to a monthly, basis.  Such
calculation, the details of which the parties agree to develop prior to January
1, 1994, would provide, for each [Confidential*] of such year, the total amount
which would have been owed by FRP and/or IMC to Partnership, or owed by
Partnership to FRP and/or IMC, as the case may be, had invoicing been conducted
on the [Confidential*] utilized in the calculation. Such [Confidential*] total
amounts for the year would be added together and the net amount obtained
thereby, constituting either an overpayment or underpayment by Partnership, as
applicable, would be duly billed or credited as appropriate in the next regular
invoices of FRP and IMC.

                         XII.  SAFETY, LIABILITY, WARRANTIES

    12.1 SAFETY DATA SHEETS.  FRP and IMC shall each furnish to Partnership
Material Safety Data Sheets, including warnings and safety and health
information concerning the products sold hereunder. Partnership agrees to
disseminate such information so as to give warning of possible hazards to
persons who Partnership can reasonably foresee may be exposed to such hazards,
including but not limited to Partnership's employees, agents, contractors or
customers.

    12.2 PRODUCT LIABILITY.  FRP and IMC shall not, under any circumstances, be
liable for any special, indirect or consequential damages of any kind of the
Partnership arising from the handling, storage or use of the sulphur when
delivered, whether used singly or in combination with other materials. No claim
of any kind, whether in contract, tort or otherwise, arising out of such
handling, storage or use, shall be greater than, nor shall FRP or IMC in any
event be liable for, an amount in excess of the purchase price of the quantity
of sulphur in respect of which such claim is made.

    12.3 WARRANTIES.  FRP AND IMC MAKE NO WARRANTY OF ANY KIND, EXPRESS OR
IMPLIED EXCEPT THAT THE SULPHUR SOLD HEREUNDER SHALL CONFORM TO THE
SPECIFICATIONS SET FORTH IN ARTICLE IX OF THIS AGREEMENT AND THAT FRP AND IMC
WILL CONVEY GOOD TITLE THERETO,  FREE FROM ANY LAWFUL SECURITY INTEREST. FRP AND
IMC ASSUME NO OTHER LIABILITY WITH RESPECT TO THE SULPHUR AND MAKE NO OTHER
WARRANTY, WHETHER OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR
OTHERWISE, EXPRESSED OR IMPLIED, WITH RESPECT THERETO.

                                XIII.  TAXES

    Partnership shall be responsible for the payment or satisfaction of any and
all taxes which may be imposed by Federal, State or local taxation authorities
after title to sulphur delivered hereunder has passed to Partnership, and shall
either (i) pay or (ii) demonstrate its exemption from any such taxes imposed
upon or levied coincident with the transfer of title to sulphur delivered
hereunder from the selling party (FRP or IMC, as applicable) to Partnership,
including but not limited to sales, use, gross receipts or other similar taxes,
but excluding income, excess profit, franchise, severance or production taxes.

                                XIV.  AUDIT

    FRP shall have the right to request and IMC will provide to FRP through
such nationally recognized independent firm of certified public accountants as
IMC shall designate a certified statement verifying that the calculation of the
[Confidential*] the [Confidential*] and IMC's [Confidential*] of sulphur
delivered to the Nichols plant have been accurately calculated and are in
accordance with the terms of this Agreement, and a certified statement that the
auditor has reviewed the records of Partnership's plants to the extent necessary
to verify that sulphur delivered to and consumed by Partnership has been
accurately calculated in accordance with the terms of this Agreement.

<PAGE>


In the event IMC or an Affiliate of IMC shall cease to be the "Operating
Partner" under Partnership's Partnership Agreement, FRP and IMC shall thereafter
during the Contract Term each have the right through such nationally recognized
independent firm of certified public accountants as FRP and IMC shall
respectively designate (other than any such firm then serving as Partnership's
auditor at the time of the audit) to audit the records of Partnership's plants
to the extent necessary to provide the same [Confidential*] and sulphur delivery
and consumption verifications as theretofore were provided FRP by IMC's auditor
pursuant to the preceding sentence.

                             XV.  FORCE MAJEURE

    Provided a party hereto promptly notifies the other parties hereto thereof,
such party shall not be liable for any failure or delay in performance hereunder
which may be due in whole or in part to fire, explosion, earthquake, storm,
flood, drought or other adverse weather condition, accident, breakdown of
machinery or facilities including, but not limited to, the transportation,
terminal and handling facilities which may be employed in making deliveries
hereunder, transportation or handling difficulties, faults or errors in
navigation (including, but not limited to, any act or omission of carriers or
terminal operators), strike, lockout, combination of workmen or other labor
difficulties (from whatever cause arising, and whether or not the demands of the
employees are reasonable or within such party's power to grant), war,
insurrection, riot, act of God or the public enemy, law, act, order,
proclamation degree, regulation, ordinance, instruction or request of Government
or other public authorities, judgment or decree of a court of competent
jurisdiction, delay or failure of carriers or contractors, labor shortage, or
inability to obtain transportation equipment, operating materials, plant
equipment or materials required for maintenance or repairs, curtailment or
suspension of operations to remedy or avoid an actual or alleged violation or
violations of Federal, State, or local environmental, health or safety standards
as may be in effect from time to time during the contract period, or any other
contingency or delay or failure or cause of any nature beyond the reasonable
control of such party, whether or not of the kind hereinabove specified and
whether or not any such contingency is presently occurring or occurs in this
future. In the event that the transportation, handling or delivery capability of
FRP is impeded due to any such cause or causes FRP shall have the right to
reduce deliveries and to allocate its facilities in such manner as appears to it
to fairly apportion the consequences of such cause or causes among FRP's
customers, and FRP shall not be obligated to take any action which would remelt
in increasing its cost of performance beyond the cost which it would have
incurred in the absence of such cause or causes.

                     XVI.  SULPHUR SALES BY FRP TO IMC

    FRP and IMC shall not be precluded from entering into agreements whereby
FRP could sell to IMC a portion of the Supplemental Sulphur which IMC would be
obligated to supply to Partnership.

                  XVII.  FRP USE OF PARTNERSHIP FACILITIES

    17.1 STORAGE AND REDELIVERY.  FRP may deliver sulphur to any Partnership
plant for redelivery therefrom at such time and in such manner as FRP shall
specify, subject to Partnership's agreement that any such Delivery and
redelivery will not disrupt operations at such plant.  FRP shall reimburse
Partnership for actual costs incurred by Partnership in connection with and
reasonably related to any such delivery and redelivery.

    17.2 BARGE FACILITIES. FRP shall have the right to fleet barges at docks or
other line-up facilities at the Faustina, Taft and/or Uncle Sam plants at any
time or from time to time provided Partnership determines such fleeting does not
cause interference with plant operations. FRP shall reimburse Partnership for
any actual costs incurred by Partnership as the result of, and reasonably
related to, such fleeting.

    17.3 OTHER USES.  With respect to Partnership facilities at the plants
owned by FRP prior to formation of Partnership, FRP shall be entitled to
continue to use such facilities provided (i) such use will not unduly interfere
with operations of Partnership, (ii) FRP reimburses Partnership for any actual
costs incurred by Partnership as the result of, and reasonably related to, such
use and (iii) FRP shall have first obtained the consent of Partnership (which
consent shall not be unreasonably withheld).

    17.4 INDEMNITY.  FRP shall defend, indemnify and hold harmless Partnership
against any and all liability arising out of or in any way connected with FRP's
use of Partnership facilities pursuant to this Article XVII including 

<PAGE>


but not limited to liability for injury, sickness, death and property damage 
provided, however, that if Partnership has contributed to such liability 
through gross negligence or willful misconduct, FRP's indemnity to 
Partnership shall be reduced by the proportion in which Partnership's grows 
negligence or willful misconduct contributed to such liability. In the event 
any claim or demand as to which such indemnity relates is made on 
Partnership, Partnership shall provide FRP with reasonable notice and 
opportunity to defend. FRP shall carry liability insurance adequate to the 
liability assumed by it hereunder. FRP shall reimburse Partnership for the 
actual cost of any additional insurance which Partnership deems reasonably 
necessary to insure its facilities against any and all liabilities which may 
arise due to FRP's use fief Partnership facilities pursuant to this Article 
XVII.

                     XVIII.  COMMERCIAL IMPRACTICABILITY

    The parties acknowledge that the allocation and pricing provisions of
Articles IV and V are based on assumptions about Partnership operations and
sulphur and sulphur transportation markets in accordance with which those
provisions are expected to yield generally balanced and equitable results.  If
fundamental changes in those operations or markets render such an assumption
invalid and performance of this Agreement by a party becomes commercially
impracticable or grossly inequitable, that party may so notify the other
parties, setting forth its reasons in reasonable detail. The parties will
negotiate in good faith toward amending the affected provisions of the Agreement
in a manner intended to restore its balance and equity. Ordinary cyclical
changes in markets shall not be grounds for invoking negotiation under this
Article. A party invoking negotiation will have the burden of proving that an
assumption upon which the Agreement was based has fundamentally altered.

                          XIX.  SUCCESSOR MANAGER

    In the event IMC or an Affiliate of IMC shall cease to be the "Operating
Partner" under Partnership's Partnership Agreement, then with respect Into IMC's
rights and obligations to supply sulphur hereunder:

    (a)  IMC Main Pass Sulphur will be supplied to the Partnership by IMC and
         otherwise dealt with hereunder in the same manner as would be the case
         if IMC continued having responsibility for general management of the
         Partnership; and

    (b)  the rights and obligations of IMC to supply hereunder sulphur other
         than IMC Main Pass Sulphur shall vest in Partnership.

    As the result of the vesting of such rights and obligations pursuant to
subclause (b) above, the Partnership shall assume the Sulphur purchasing
functions theretofore performed by IMC in connection with IMC's non-IMC Main
Pass Sulphur supply obligations hereunder, and, accordingly the pricing
provisions of Article V, [Confidential*] shall thenceforward be based upon the
[Confidential*] of the [Confidential*].

                               XX.  NOTICES

    Any notice, election, payment or other correspondence required or permitted
under this Agreement shall be made in writing and shall be sufficiently

                          XXII.  SATCO  EXCHANGES

    FRP, directly or through FRP's affiliate, Sulphuric Acid Trading Company
("SATCO"), shall have the right at any time and from time to time to deliver to

<PAGE>


                    ADDENDUM NO. 1 TO AGREEMENT FOR SULPHUR SUPPLY

    This Addendum No. 1, dated as of January 1, 1994 ("Addendum") to AGREEMENT
FOR SULPHUR SUPPLY, dated July 1, 1993 ("Agreement") is entered into among
Freeport-McMoRan Resource Partners, Limited Partnership ("FRP"), IMC Fertilizer,
Inc. ("IMC"), and IMC-Agrico Company ("IMC-Agrico"). Captioned terms used herein
without definition shall have the same meaning given them in the Agreement.

    Now, therefore FRP, IMC and IMC-Agrico hereby agree to determine the
quantity of ''Excess IMC Sulphur" (EIS), defined in Section 1.08 of the
Agreement as of the close of any month as follows:

    Quantity of IMC sulphur over/(under) supplied to "Partnership Plant" as
calculated by Schedule B of the Agreement......................................#

    Plus...IMC sulphur held by FRP in liquid inventory for whatever reason from
all sources including but not limited to, sulphur acquired from arms-length
purchase contracts, sulphur residing with FRP under transportation or
terminating agreements, sulphur sales by FRP to IMC pursuant to Section XVI fit
the Agreement, IMC sulphur acquired through exchanges, and sulphur withdrawn
from solid inventory for IMC's account by FRP, but excluding Allowable IMCF
Working Liquid Inventory ("IMCWLI") and IMCF Sulphur as defined below..........#

    Less IMCWLI...........................................................12,000

    Equals EIS.................................................................#

    Upon mutual agreement of all parties, the IMCWLI may be revised upward or
downward from time-to-time. Adjustments, for the most part will be determined by
transportation and/or terminal contractual agreement(s) between IMC and FRP for
the use of FRP facilities by IMC.

    Within seven business days following IMC's receipt of a written notice from
FRP to IMC of the existence of EIS, IMC shall notify FRP in writing of the
liquidation option that FRP shall use to dispose of the EIS.  Liquidation
options shall include the following:

    A.    FRP markets EIS on behalf of IMC when market conditions allow, or

    B.   EIS is vatted by FRP for IMC's account.

    FRP's notice to IMC of the existence of an EIS shall include the market
sales price which FRP can obtain and the commercial arrangements to compensate
FRP for its services under liquidation option A and FRP's solid sulphur
inventory costs associated with liquidation option B.  Depending upon IMC's
liquidation option, IMC shall execute a sulphur marketing agreement or solid
storage agreement with FRP containing the cost terms contained in the EIS
notice.  Should IMC fail to execute such an agreement within seven business days
following IMC's receipt of notice from FRP to IMC of the existence of EIS, all
EIS shall be considered as placed in solid inventory for IMC's account pursuant
to liquidation option B.

<PAGE>


ADDENDUM NO 1 TO AGREEMENT FOR SULPHUR SUPPLY

The storage cost of sulphur and solid inventory is time sensitive.  Labor, fuel,
equipment and environmental costs will change over time.  From time-to-time,
and/or as required, revised costs will be provided to IMC.  Accordingly,
Freeport will make best efforts to identify representative costs associated with
vatting and melting sulphur in parcels of 50,000 tons. Requests by IMC to vat or
melt in quantities less than 50,000 tons could result in additional costs. 
FRP's 1994 solid sulphur inventory handling costs are as follows:

    Vatting Charge .......... [Confidential*] (invoiced as EIS is placed into
solid inventory)
    Melting Charge ......... [Confidential*] (invoiced as EIS is withdrawn from
solid inventory)

IMCF SULPHUR

    In determining solid storage vatting and melting requirements and the costs
attributable thereto, the terms and provisions of the Processing and
Transportation Agreement, as amended, between Freeport Sulphur Company, a
division of Freeport McMoRan Resource Partners Limited Partnership, and IMC
Fertilizer, Inc., dated December 1, 1989, shall apply.

    In witness hereof, the parties hereto have caused this Addendum to be
executed as of the date first above written.

This Amendment, dated July 1, 1994 by and between Freeport-McMoRan Resource
Partners, Limited Partnership ("FRP"), IMC Fertilizer, Inc. ("IMC") and
IMC-Agrico Company ("IMC-Agrico").

                            W I T N E S S E T H:

WHEREAS, FRP, IMC and IMC-Agrico entered into that certain Agreement for Sulphur

                      RE: Agreement for Sulphur Supply dated July 1, 1993
                          among Freeport-McMoRan Resource Partners,
                          Limited Partnership, IMC Fertilizer Inc. and IMC-
                          Agrico Company (the "Sulphur Supply Agreement")

Gentlemen:

     In connection with the transactions contemplated in the Agreement and 
Plan of Merger dated August 26, 1997 between IMC Global Inc. and 
Freeport-McMoRan Inc. (the "Merger Agreement"), FRP will transfer its 
interest in the Sulphur Supply Agreement to the company referred to in the 
Merger Agreement as "Newco". (Terms not otherwise defined in this letter will 
have the meaning ascribed to them in the Merger Agreement.) A question has 
arisen in connection with Article III of the Sulphur Supply Agreement 
relating to its term. In consideration of the benefits anticipated by them in 
connection with the transactions contemplated in the Merger Agreement, FRP 
and IGL wish to record their understanding as follows.

     IGL and FRP acknowledge that, while not contemplated at this time, a 
transaction or series of transactions could take place in the future as a 
result of which IMC-Agrico Company's (the "Partnership's") phosphate 
fertilizer operations could be acquired by transfer tor by operation of law by 
IGL or a company controlling, controlled by or under common control with IGL 
(an "Affiliate"), with or without the consequent termination of the 
Partnership (an "IGL Acquisition Transaction"). IGL and FRP acknowledge and 
agree that the "business of the Partnership" and the term of the Sulphur 
Supply Agreement, as intended by Article III of the Agreement, will not be 
deemed to end as a result of an IGL Acquisition Transaction.

     This agreement is not intended to amend Article III or any other term of 
the Sulphur Supply Agreement and is intended to be for the benefit of and 
binding on FRP, Newco, IGL and its Affiliates, and the successors and assigns 
of any of them.

                                    Yours truly,
 
                                    Freeport-McMoRan Resource Partners,

                            II. SCOPE OF AGREEMENT

     2.1   GENERAL.  Freeport will take receipt of the Felmont Sulphur at the 
Receiving Point, commingle the same with Freeport Sulphur, and sell Felmont's 
share of such commingled sulphur to purchasers. Freeport will perform, in 
accordance with the terms and conditions hereinafter set forth, all services 
required between receipt and sale of such sulphur, including storage, 
filtration, blending, purification (by means other than blending, if 
required), vatting, melting, loading into transportation equipment, marketing 
and associated transporting and terminalling services.

     2.2  OTHER AGREEMENTS. Freeport's entry into this Agreement shall in no 
way limit Freeport's right to enter into agreements with other parties to 
perform for such parties any services of the kind to be rendered hereunder; 
provided, however, Freeport shall not knowingly enter into any agreement that 
would adversely affect performance of Freeport's obligations under this 
Agreement, and further provided, that no such third party agreement shall 
provide to any such third party any priority that is above that afforded to 
Felmont or otherwise Consistent with the following:

          (i)  With respect to the use of Initial Facilities, no third party 
shall have any priority that is above the priority afforded to Felmont;

          (ii) With respect to the use of New and Replacement Facilities for 
which Felmont pays any adjustment to the Facilities recharge pursuant to 
Article 10, all such third party priorities shall be below the priority 
afforded to Felmont unless such third party is obligated to pay a 
proportionate share of the capital cost (including the Reasonable Cost of 
Capital associated therewith) of such New or Replacement Facility in which 
latter case such third party priority shall be equal to the priority afforded 
Felmont.

     2.3  SPARE CAPACITY.  In the event Freeport enters into any agreement to 
provide services to any third party utilizing the spare or idle capacity of 
any Facility, the revenue received by Freeport for such services shall be 
retained by Freeport. All operating costs for such services shall be for the 
account of Freeport. For purposes of this Section 2.3, "operating costs" shall 
have the same meaning as it has in Section 6.1(i). No reduction to the base 
Facilities Charge or to any adjustment to the Facilities Charge shall be made 
as a consequence of the use of such spare or idle capacity for provision of 
such services to third parties unless such Facility is a New or Replacement 
Facility that has incremental or surplus capacity in which case the 
adjustment shall be made as provided in Section 10.3.

                               III. QUANTITY

     This Agreement shall apply to 100% (one hundred percent) of the Felmont 
Main Pass Sulphur produced during the term of this Agreement, including the 
Purchase Requirement Period, and 100% (one hundred percent) of the Felmont 
Blending Sulphur delivered to the Port Sulphur Terminal as provided in 
Article VII.

providing to Felmont monthly sales and inventory reports related to all such 
activities). Monthly sales reports provided to Felmont shall indicate the 
total quantity sold in each market served by Freeport and the average sales 
realization in each such market. All marketing information to be furnished by 
Freeport hereunder is deemed by Freeport to be confidential and Felmont 
agrees that it shall treat such information in the same manner Felmont treats 
its own confidential information.

     5.6  Arranging for all transportation equipment and labor required to 
deliver Felmont Sulphur to customers, including use of Freeport's own 
transportation equipment and labor and such equipment and labor as Freeport 
may contract from Freeport's Related Parties and third parties.

     5.7  Loading and delivery of Felmont Sulphur into transportation 
equipment. In the event of a shortage in sulphur vessel capacity subject to 
Freeport's control, first and equal priority shall be given to the transport 
of Freeport's sales tonnage (including tonnage sold by Freeport on Felmont's 
behalf and tonnage consumed by Freeport or Freeport's Related Parties), 
sulphur produced at the Main Pass Mine, sulphur to be moved for others 
pursuant to shared transportation equipment commitments, and sulphur used 
for blending or vatting; second priority shall be given to all other Freeport 
uses of its transportation equipment.

     5.8  With respect to customers taking delivery of Felmont Sulphur at or 
through the Tampa Terminal or another Freeport receiving facility as

    From and after the Commencement Date, for the services rendered by 
Freeport pursuant to Article V hereinabove and pursuant to Articles VII, VIII 
and XVI hereinafter, Felmont shall pay Freeport the Operating Cost 
Reimbursement plus the Management Fee plus the Facilities Charge plus the 
Marketing Fee as described below:

                                      10

<PAGE>

     6.1  OPERATING COST REIMBURSEMENT.

         (i)   Freeport shall be entitled to reimbursement of its actual 
               operating costs incurred in rendering services under this 
               Agreement (except for the services described in Section 5.5 
               hereinabove for which Freeport shall be compensated by the 
               Marketing Fee described in Section 6.4 below) without 
               duplication of any item of cost incurred under this Agreement 
               and any other agreement between Freeport and Felmont. Charges 
               from Freeport's Related Parties which are included in 
               Operating Cost Reimbursement shall be no less favorable to 
               Felmont than would be the case if such services were purchased 
               in an arm's-length transaction; provided however, such charges 
               from Related Parties shall in any event fully reimburse 
               Freeport, without any profit, for any and all direct and indirect
               costs incurred. Freeport shall keep accurate records of such 
               actual operating cost (including costs from Freeport's Related 
               Parties or other third parties, but excluding G & A 
               [subject to the provisions of Section 6.5 hereof] and 
               depreciation) incurred each month in rendering the services 
               described in Articles V, VII, VIII and XVI in respect of 
               Felmont Sulphur. In this regard Freeport shall cause cost 
               records to be kept for each activity center (e.g. 
               purification, vatting, etc.) so that an average cost incurred 
               per ton of all sulphur moved through such activity center 
               during a month may be determined and charged proportionally 
               to each quantity of sulphur moved through the activity center 
               during such month. Such actual operating cost shall include the 
               full cost of services rendered by any Freeport Employee 
               specifically for the performance of this Agreement, the 
               charges for such services shall reflect not only an allocation 
               of such Freeport Employee's wages (including bonuses), but 
               also a fair and equitable allocation of that Freeport 
               Employee's benefits and departmental overhead (as opposed to 
               G & A). Operating Cost Reimbursement shall include, at 
               Freeport's option, Felmont's estimated proportionate share of 
               Closure Costs of any Facility or Facilities, the amount of 
               such accrual to be determined on a net present value basis or 
               other basis which reflects Felmont's pre-payment of such 
               estimated proportionate share of Closure Costs.

         (ii)  Freeport shall invoice Felmont for reimbursement of such 
               actual cost, and for payment of the associated Management Fee 
               described in Section 6.2 below, during the following month.

     6.2  MANAGEMENT FEE. Freeport shall be entitled to a Management Fee for 
performing the services described in Articles V (other than those described 
in Section 5.5), VII, VIII and XVI, which such fee shall be payable monthly 
and shall be equal to 5% of the total Operating Cost Reimbursement applicable 
tic such month; provided, however, that for the month during which

                                       11

<PAGE>

the Commencement Date occurs and for each of the next succeeding 35 months 
thereafter, the Management Fee shall in no event exceed sixty cents ($.60) 
per ton of Felmont Main Pass Sulphur received at the Receiving Point during 
any such month. The Management Fee shall not be applicable to any G & A for 
which Freeport may become entitled to reimbursement through the Operating 
Cost Reimbursement pursuant to the provisions of Section 6.5 hereof, nor to 
the amount paid for purchased sulphur pursuant to Section 7.3 nor to 
Felmont's share of Closure Costs.

     6.3  FACILITIES CHARGE. Freeport shall be entitled to a fee for the use 
of Freeport's facilities in rendering the services described in Articles V 
(other than those described in Section 5.5), VII and VIII. Fifteen (15) days 
after the beginning of each quarter after the Commencement Date, Freeport 
shall estimate the quantity of Felmont Main Pass Sulphur to be received 
during such quarter and shall invoice Felmont a Facilities Charge which shall 
be $3.00 (three dollars) per ton of such estimated tonnage until and unless 
such amount is adjusted as provided in Article X. The actual tonnage of 
Felmont Main Pass Sulphur received in a current quarter will be indicated in 
the Facilities Charge invoice for the next succeeding quarter, with 
appropriate adjustment being made to the Facilities Charge for such 
succeeding quarter to reflect the actual tonnage received in the current 
quarter.

     6.4  MARKETING FEE. For each ton of Felmont Tonnage determined to have 
been sold during a month, Felmont shall pay Freeport a Marketing Fee equal to 
a specified percentage of the Average Sales Realization for such month, which 
such percentage shall be either 3% as proposed by Freeport or 2 1/4% as 
proposed by Felmont, depending upon the outcome of the arbitration procedure 
hereinafter described in this Section 6.4. On or before 30 days after the 
date of execution of this Agreement the parties shall engage the services of 
one arbitrator who shall be Dr. Russell Coleman, retired Chairman of the 
Sulphur Institute, or if he is unavailable, Mr. Douglas Borne, President of 
Battle Mountanin Gold, or if he is unavailable, Dr. Robert Wagner, Chairman 
of the Potash and Phosphate Institute, or if he is unavailable, such other 
person as the parties shall mutually agree. On or before 30 days after such 
arbitrator is engaged each of the parties shall submit to such arbitrator a 
statement, which shall be limited to 10 single spaced typewritten pages and 
supporting documentation, setting forth such party's arguments in favor of 
the percentage proposed by it. Within 10 days after the day upon which the 
arbitrator is in receipt of the statements of both parties, the arbitrator 
will choose either the 3% proposed by Freeport or the 2 1/4% proposed by 
Felmont and not substitute his own judgment that a percentage different from 
either of those would constitute a fair and equitable resolution. The 
decision of the arbitrator will be final and binding upon both parties.

     6.5  G & A. Freeport bears a portion of the G & A. Freeport has chosen 
to allocate the G & A (not otherwise allocated to a specific project) by 
dividing the G & A for a specific billing period by the total number of tons 
produced during such period from Freeport's own mines and the Main Pass Mine 
(disregarding purchased sulphur). The Main Pass Mine is treated as a special 
project for G & A allocation during the pre-production phase. After the 
Commencement Date all G & A not allocated to a specific project will be 
allocated to sulphur production. Felmont agrees 

                                       12

<PAGE>

to bear its fair and equitable share of such G & A without duplication 
through the Joint Operating Agreement and through charges under this 
Agreement. If the method for allocation of Felmont's share of such G&A under 
the Joint Operating Agreement should be changed by Freeport with the result 
that Felmont ceases to bear its fair share of such G&A through charges under 
the Joint Operating Agreement, Felmont agrees to bear its share of such G&A 
without duplication though a combination of charges under the Joint Operating 
Agreement and this Agreement.

     6.6  PAYMENT.  Felmont shall make payment for each of the Operating Cost 
Reimbursement, the Management Fee and the Facilities Charge within thirty 
days from the date of postmark of Freeport's invoice therefor and shall send 
such payment to the address set out in such invoice for receipt of 
remittances. Freeport shall be deemed to have received such payment on the 
date it is received at such address; provided, however, that if the date of 
post mark of a payment is a date 25 days or less from the date of postmark of 
Freeport's invoice, such payment shall be deemed to have been timely received 
hereunder. Felmont agrees to pay Freeport a service charge equal to the 
lesser of (i) 0.05% per day (approximately one and one-half percent (1-1/2%) 
per month), or (ii) the highest percentage interest rate then permitted by 
law, on all payments due by Felmont not received by Freeport on or before the 
date due. Payment of the Marketing Fee shall be made as provided in Section 
13.2 hereof.

                                VII. BLENDING

     Because of impurities which may be present in sulphur produced from the 
Main Pass Mine, it may be necessary from time to time to blend higher quality 
sulphur with Felmont Main Pass Sulphur in order for Felmont Main Pass Sulphur 
to meet commercial specifications. Freeport agrees to use its best efforts, 
and in the order of priority provided in Sections 7.1 through 7.3 below 
(unless transportation charges can be reduced by altering the order of 
priority), to obtain recovered sulphur or other higher quality sulphur for 
purposes of such blending in a manner to minimize the cost thereof. The 
following provisions shall apply from time to time in determining Operating 
Cost Reimbursement under Article VI, the quality of Felmont Sulphur sold and 
the quantity of Felmont Tonnage for the purposes of Schedule C. Freeport 
agrees that in allocating blending sulphur Felmont Sulphur will be treated on 
a parity with Freeport Sulphur in priority of allocation of sulphur under 
Section 7.1 through 7.3.

     7.1  WATERBORNE SULPHUR PROVIDED BY FREEPORT.  Freeport currently 
transports recovered sulphur by barge and by tanker for third parties and for 
its own use at phosphoric acid plants which Freeport owns and operates in 
Louisiana. Provided that Freeport (a) has the right to exchange recovered 
sulphur being transported for third parties, and/or (b) can utilize less than 
commercial grade sulphur in its phosphoric acid plants without operational 
difficulties or increased operating costs, then Freeport agrees to exchange 
(without charge to Felmont to reflect the differences in quality between the 
tonnages exchanged) that quantity of recovered sulphur which is necessary for 
blending with Felmont Main Pass Sulphur for an equal quantity Of Felmont Main 
Pass Sulphur. The exchanges contemplated herein shall be on a ton per ton 
basis and shall not result in 

                                      13
<PAGE>


any increase or decrease in the total quantity of Felmont Sulphur then held 
by Freeport. Risk of loss to each quantity of sulphur so exchanged shall pass 
from one party to the other at the time the blending occurs. For each ton of 
recovered sulphur so exchanged for a ton of Felmont Main Pass Sulphur, 
Freeport shall be entitled to payment as provided in Article VI hereof for 
performing the services utilized pursuant to Article V associated with such 
Felmont Blending Sulphur, except that Operating Cost Reimbursement shall also 
include one-half (but only one-half) of the transportation costs associated 
with transporting such quantity of recovered sulphur from the place of 
receipt at a port facility to the Port Sulphur Terminal. Felmont shall bear 
no portion of any cost of shipment of Felmont Main Pass Sulphur so exchanged 
from the Port Sulphur Terminal to another location.

     7.2  SULPHUR PROVIDED BY FREEPORT FROM ITS PHOSPHORIC ACID PLANTS.  
Freeport also currently transports recovered sulphur by rail and truck for 
use at its phosphoric acid plants in Louisiana. Provided that Freeport (a) 
can utilize less than commercial grade sulphur in its phosphoric acid plants 
without operational difficulties or increased operating costs, and (b) has 
recovered sulphur available, then Freeport agrees to exchange (without charge 
to Felmont to reflect the differences in quality between the tonnages 
exchanged) that quantity of recovered sulphur which is necessary for blending 
with Felmont Main Pass Sulphur for an equal quantity of Felmont Main Pass 
Sulphur. The exchanges contemplated herein shall be on a ton per ton basis 
and shall not result in any increase or decrease in the total quantity of 
Felmont Sulphur then held by Freeport. Risk of loss or damage to each 
quantity of sulphur so exchanged shall pass from one party to the other at 
the time the blending occurs. For each ton of liquid recovered sulphur so 
exchanged for a ton of Felmont Main Pass Sulphur, Freeport shall be entitled 
to payment as provided in Article VI hereof for performing the services 
utilized pursuant to Article V associated with such Felmont Blending Sulphur, 
except that Operating Cost Reimbursement shall also include the full cost of 
loading such liquid recovered sulphur into a barge at Freeport's phosphoric 
acid plant and transporting such recovered sulphur from the phosphoric acid 
plant to the Port Sulphur Terminal, and transporting the exchanged Felmont 
Main Pass Sulphur from such terminal to Freeport's phosphoric acid plant.

     7.3  SULPHUR PURCHASED BY FREEPORT FOR BLENDING.  If the quantity of 
recovered sulphur available pursuant to Sections 7.1 and 7.2 above is less 
than the quantity required for blending with Felmont Main Pass Sulphur, 
Freeport shall consult with and obtain Felmont's approval (which shall not be 
unreasonably withheld) before purchasing any sulphur for blending with 
Felmont Main Pass Sulphur. If Freeport purchases recovered sulphur for 
blending with Felmont Main Pass Sulphur, Freeport shall be entitled to 
payment as provided in Article VI hereof for performing the services utilized 
pursuant to Article V associated with such Felmont Blending Sulphur, except 
that Operating Cost Reimbursement shall also include Felmont's proportionate 
share of the full cost of purchasing and transporting such recovered sulphur 
from the point of purchase to the Port Sulphur Terminal. All such Felmont 
Blending Sulphur so purchased for Felmont's account shall be added to the 
quantity of Felmont Sulphur then in the possession of Freeport and risk of 
loss or damage to such Felmont Blending Sulphur so purchased shall pass to 
Felmont at the shoreline

                                      14
<PAGE>


flange at the Port Sulphur Terminal as such Felmont Blending Sulphur is 
progressively discharged into such Facility from the transportation equipment 
transporting such sulphur to such terminal.

                                 VIII. VATTING

     In determining solid storage vatting costs attributable to Felmont 
Sulfur, Freeport shall be entitled to reimbursement as an Operating Cost 
Reimbursement for the full cost of the vatting and melting of such sulphur if 
undertaken as the result of a decision by Freeport in its capacity as 
marketing agent that it expects such vatting to benefit Average Sales 
Realization, or if as the result of a force majeure affecting Freeport's 
terminalling and/or transportation system. Should it become necessary, 
because of anticipated future shortages of recovered sulphur or for other 
reasons, to vat Felmont Blending Sulphur obtained for blending with Felmont 
Main Pass Sulphur, Freeport shall consult with and obtain Felmont's approval 
(which shall not be unreasonably withheld) before any such Felmont Blending 
Sulphur is vatted. If Freeport vats any Felmont Blending Sulphur, Freeport 
shall be entitled to reimbursement as an Operating Cost Reimbursement, for 
the full cost of the vatting and melting of such Felmont Blending Sulphur. 
Should Freeport elect to vat a quantity of Freeport Sulphur or sulphur of any 
Freeport Related Party at the Port Sulphur Terminal principally for the 
economic benefit of Freeport or such Related Party is a party, or principally 
for purposes of maintenance of recovered sulphur purchase contracts to which 
Freeport or any Freeport Related Party is a party, and not substantially for 
the benefit of Felmont, Felmont shall bear no portion of the cost of services 
specified in Articles V, VII, VIII and XVI with respect to such quantity of 
sulphur.

                     IX.  OPERATIONAL AND PROCESS LOSSES

     The parties acknowledge that in the course of operations and processes 
required for receiving, handling, storing, purifying, filtering, 
transporting, loading and unloading Felmont Sulphur, some portion of such 
sulphur will be lost and, from time to time, gained. The parties agree that 
such operational and process losses and gains shall be estimated and 
allocated among the particular processes in which such changes occur, by such 
method or methods as Freeport shall from time to time determine, subject to 
adjustment based on total loss or gain determinations made from time to time 
by actual physical measurement. The quantity of Felmont Sulphur which is held 
be Freeport from time to time shall be determined by totaling all receipts of 
Felmont Main Pass Sulphur and Felmont Blending Sulphur and subtracting (or 
adding in the case of the operational gains) therefrom (i) the operational 
and process losses and gains) (ii) all deliveries of Felmont Sulphur made to 
purchasers, and (iii) any Felmont Sulphur which is lost or destroyed due to 
reasons beyond Freeport's reasonable control.

     Freeport shall from time to time make analyses of sulphur in the course 
of such operations and processes in order to establish the quantities and 
characteristics of such sulphur. Freeport shall deliver to Felmont reports of 
such analyses at least monthly. Felmont shall have the right at Felmont's

                        X. ADDITIONAL CAPITAL

     10.1  FREEPORT'S COMMITMENT RELATED TO FACILITIES IMPROVEMENT, SCHEDULE. 
Freeport represents, in good faith, that the expansions and modifications of 
Existing Facilities set forth in the Facilities Improvement Schedule will 
bring the processing and storage facilities at the Port Sulphur Terminal and 
at the Tampa Terminal into a condition suitable for providing the services to 
be rendered under the Agreement: but it is expressly understood that the 
transgulf transportation facilities listed on Schedule A hereof may not be 
sufficient to provide adequate reserve transportation capacity so that 
additional capital expenditures in respect thereof may be required at some 
future time. Freeport shall invest, at Freeport's sole expense, the 
additional capital required to accomplish the expansions and modifications 
indicated in the Facilities Improvements Schedule and shall notify Felmont in 
writing of the date upon which such expansions and modifications have been 
accomplished.

     10.2  OTHER PRE-COMMENCEMENT DATE CAPITAL EXPENDITURES. Notwithstanding 
the foregoing provisions of Section 10.1, if an additional capital 
expenditure not shown on Schedule B is determined by Freeport to be required 
prior to the Commencement Date:

           (i)   for Existing Facility expansion and modification as the 
                 result of changes in applicable environmental or other laws 
                 and/or regulations in effect as of December 31, 1989, or new 
                 interpretations of such applicable environmental or other 
                 laws and/or regulations in effect as of such date which are 
                 made after such date, or other event beyond the reasonable 
                 control of Freeport; or 

           (ii)  for replacement of Initial Facilities as the result of loss 
                 or damage beyond the reasonable control of Freeport and such 
                 replacement, after taking into account salvage value and/or 
                 insurance proceeds, requires additional capital to improve 
                 the economics of overall operations or is dictated by 
                 factors not within the control of Freeport (Freeport agrees 
                 to maintain, from the date of execution of this Agreement 
                 until the Commencement Date, insurance on the Initial 
                 Facilities in an amount which it, in good faith, believes 
                 will reflect in the case of vessels, adequate Hull insurance 
                 coverage and, in the case of all other such Initial 
                 Facilities, the replacement cost thereof);

such determination having been made on the basis that such capital 
expenditure is substantially for the purpose of providing services in respect 
of sulphur to be produced from the Main Pass Mine, Felmont shall bear its 
proportionate share (determined on the same basis as provided in Section 10.3 
below) of such additional capital expenditure (including the Reasonable Costs 
of 

                                  16

<PAGE>

Capital associated therewith) through an adjustment of the Facilities Charge 
in the same manner as provided in Section 10.3 below with respect to a 
Replacement Facility of a New Facility, except that any such expansion or 
modification project undertaken or any replacement for a Facility constructed 
or otherwise acquired prior to the Commencement Date with a cost in excess of 
$500,000 (which amount is subject to adjustment as provided in Section 10.7) 
shall be subject to Felmont's approval which shall not be unreasonably 
withheld. Except as otherwise provided in this Section 10.2, any such 
expansion or modification project undertaken as contemplated by this Section 
10.2 shall for all other purposes of this Agreement be deemed to be a New 
Facility and any such replacement for a Facility constructed or otherwise 
acquired as contemplated by this Section 10.2 shall for all other purposes of 
this Agreement be deemed to be a Replacement Facility.

     10.3  NEW AND REPLACEMENT FACILITIES. From and after the Commencement 
Date, a proportionate share of the cost of each capital expenditure made by 
Freeport in respect of Facilities used by it to perform services under this 
Agreement, whether made in respect of a Replacement Facility or in respect of 
a New Facility, plus the Reasonable Cost of Capital associated therewith, 
shall be borne by Felmont in the form of an adjustment to the basic $3.00 per 
ton Facilities Charge specified in Section 6.3 hereof. If in determining the 
size or capacity, of a New Facility or Replacement Facility, Freeport 
includes in the size or capacity of such Facility incremental or surplus 
capacity (in excess of that reasonably needed for contingencies) in order to 
provide services to third parties, then the adjustment to the Facilities 
Charge shall (i) be no greater than it would have been had such Facility been 
sized not to exceed the reasonable service requirements of sulphur production 
from the Main Pass Mine plus Freeport's other sulphur mines in the Gulf 
Coast area, and (ii) reflect for the benefit of Felmont any reduction in the 
Facilities Charge adjustment resulting from such incremental or surplus 
capacity as compared to the Facilities Charge adjustment that would have 
resulted from such a Facility without incremental or surplus capacity.

     Felmont's proportionate share of such capital expenditure shall be 
determined (and thereafter fixed) at the time of the capital expenditure is 
made for such Facility based on the percentage of the capacity of such 
Facility reasonably estimated to be for the benefit of Felmont Sulphur. The 
adjustment to the Facilities Charge in accordance with the preceding 
paragraph will reflect Felmont's proportionate share of the cost of the 
Facility so constructed or acquired, plus the Reasonable Cost of Capital 
associated therewith, as depreciated over the useful life of the Facility in 
accordance with a schedule of depreciation to be provided at the time of 
construction or acquisition. When Felmont has paid Freeport its full 
proportionate share of a capital expenditure, plus the Reasonable Cost of 
Capital associated therewith, which is attributable to Felmont Sulphur, the 
adjustment to the basic $3.00 per ton Facilities Charge associated with such 
capital expenditure shall no longer be applied. Any Freeport decision to 
replace any of the Initial Facilities with a Replacement Facility requiring 
an expenditure in excess of $3,000,000 (which amount is subject to adjustment 
as provided in Section 10.7) or to add any New Facility requiring an 
expenditure in excess of $500,000 (which amount is subject to adjustment as 
provided if Section 10.7), shall be subject to Felmont's approval, with 
approval shall not be unreasonably withheld.

                                  17

     10.4  REFERRAL TO CHIEF EXECUTIVE OFFICERS. In the event that 
representatives of Felmont and Freeport are unable to agree on the need to 
add a Replacement Facility, or a New Facility, its the case may be, which 
requires the approval of Felmont in accordance with Sections 10.2 or 10.3 
above, the matter shall be referred to the chief executive officers of 
Felmont's intimate parent company and Freeport's ultimate parent company for 
their decision. If the parties remain unable to agree at the end of 30 days 
after such referral, the matter shall be resolved in accordance with the 
provisions of Article XI hereof entitled "Additional Capital Dispute 
Resolution." Notwithstanding anything in this Agreement, or any decision 
rendered pursuant to Article XI, to the contrary, Freeport reserves the right 
at all times to proceed in its sole discretion with any capital expenditure 
for its own use and for its own accounts, and the only effect of Felmont's 
approval or disapproval of a capital expenditure will be whether such capital 
expenditure shall be utilized by Freeport in performing services under this 
Agreement and whether Felmont has an obligation to pay a Facilities Charge 
associated therewith.

     10.5  ENVIRONMENTAL AUDITS. Felmont shall have the right to conduct, at 
Felmont's expense, an environmental audit prior to use of, and/or upon 
abandonment of, and/or upon notice to Felmont pursuant to Section 10.6.3 of 
Freeport's continued use of, and/or upon Felmont's termination of this 
Agreement, any Facilities utilized by Freeport in the performance of this 
Agreement (inclusive of the Initial Facilities plus all replacements and 
additions thereto); provided, however, that in the conduct of any such 
environmental audit no contact shall be made with any personnel of any federal, 
state, local or other government, and none of the information obtained in the 
conduct of such audit shall be released to any person other than a director, 
officer, employee or consultant of Felmont or of a Felmont Related Party, 
without the prior written consent of Freeport unless Felmont determines that 
it is legally obligated to disclose such information and gives Freeport 
reasonable advance written notice of its intention to make such a disclosure.

     10.6  DISPOSITION OF FACILITIES. Subject to the further provisions of 
this Section 10.6, the disposition of any Initial Facility, Replacement 
Facility or New Facility (i) after this Agreement has terminated, or (ii) at 
any time after Freeport has determined that any such Facility is no longer 
appropriate for the performance of this Agreement, shall be made as Freeport 
in its sole discretion shall decide.

           10.6.1 Should Freeport in its discretion choose to scrap or sell a 
                  Facility, Felmont shall bear a proportionate share of (i) 
                  the Closure Coat of the Facility, and (ii) any remaining 
                  unrecovered cost of the Facility (but excluding the 
                  unrecovered cost of any Initial Facility identified on the 
                  Existing Facilities Schedule), if any, after taking salvage 
                  value (or sales proceeds, as the case may be) into account. 
                  In the case of a Replacement Facility or a New Facility 
                  such proportionate share shall be the proportionate share 
                  determined to be Felmont's proportionate share for purposes 
                  of adjusting the Facilities Charge to reflect the addition 
                  of such Replacement Facility or New Facility. In the case 
                  of an Initial Facility such proportionate share

                                  18
<PAGE>

                  shall be based upon the percentage of utilization of such 
                  Initial Facility for the benefit of Felmont Sulphur during 
                  the period this Agreement was in effect prior to scrapping 
                  or sale, as the case may be; provided, however, that with 
                  respect to the Closure Cost, if any, of an Initial 
                  Facility, the parties recognize that a portion of such cost 
                  may be the result of Freeport's use of the Initial Facility 
                  prior to or after performing services under this Agreement 
                  and will develop a fair and equitable method or methods for 
                  relieving Felmont of responsibility for such portion of 
                  such cost. If Freeport has elected to charge Felmont an 
                  amount as an accrual for Closure Cost as provided in 
                  Section 6.1(i) and Felmont's proportionate share of the 
                  actual Closure Cost is more or less than Felmont's 
                  proportionate share of the estimated Closure Cost on which 
                  the accrual was calculated or the amount actually accrued, 
                  then Freeport will develop a fair and equitable method for 
                  reimbursing or crediting Felmont for such excess amount 
                  accrued for Closure Cost and Felmont shall reimburse 
                  Freeport for any under accrual for Closure Cost.

           10.6.2 Should Freeport in its discretion sell a Facility (other 
                  than an Initial Facility) and the sales proceeds therefrom 
                  are greater than the depreciated book value (cost less 
                  depreciation), Freeport will develop a fair and equitable 
                  method for reimbursing Felmont for any overpayment of 
                  Facilities Charges in a manner which takes into account the 
                  extent that Felmont has contributed to the depreciation of 
                  such Facility. Neither this Section 10.6.2 nor any other 
                  provision of this Agreement shall be construed or is 
                  intended to grant to Felmont any ownership right, lien, 
                  encumbrance, equitable or beneficial interest in any 
                  Facility (whether an Initial Facility or a Replacement 
                  Facility or a New Facility) now or at any time in the 
                  future or impose any liability or responsibility on Felmont 
                  to third parties with respect thereto.

           10.6.3 Should Freeport in its discretion choose to continue to use 
                  or permit a Freeport Related Party to use a Facility 
                  exclusively for purposes other than performing the services 
                  to be rendered under this Agreement, either after having 
                  determined that such Facility is no longer necessary or 
                  appropriate for the performance of this Agreement or after 
                  termination of this Agreement (provided such Facility does 
                  not qualify as an Early Termination Facility subject to the 
                  provisions of Section 10.6.4 below), Freeport shall so 
                  notify Felmont and Felmont shall, except as otherwise 
                  provided in the next following sentence, be relieved of all 
                  further financial responsibility for and right to surplus 
                  proceeds from such Facility as of the date of such notice 
                  from Freeport. If after giving such notice of continued 
                  use, Freeport should choose to scrap or sell such Facility, 
                  as the case may be, and such 

                                  19
<PAGE>

                  scrapping or sale entails a Closure Cost, Felmont shall 
                  bear its proportionate share of such Closure Cost. 
                  Felmont's proportionate share shall be determined in the 
                  manner provided in Section 10.6.1 above for the period of 
                  time when this Agreement was in effect, and Felmont shall 
                  have no responsibility for any portion of such Closure Cost 
                  relating to utilization of the Facility before or after 
                  that period of time. Further, if the Facility so used 
                  exclusively for purposes other than performing the services 
                  to be rendered under this Agreement is a New Facility or a 
                  Replacement Facility for which an adjustment to the 
                  Facilities Charge is still being charged to Felmont, then 
                  for the period of time that the Facility is so used for 
                  other purposes, Felmont shall receive a credit for and be 
                  forever relieved of the obligation to pay the Facilities 
                  Charge adjustment associated with such Facility.

           10.6.4 In the event this Agreement should terminate prior to the 
                  tenth anniversary of the Commencement Date, and Freeport in 
                  its discretion should choose to continue to use an Early 
                  Termination Facility exclusively for purposes other than 
                  performing the services to be rendered under this 
                  Agreement, Freeport shall so notify Felmont and Felmont 
                  shall, within 30 days after the date of Freeport's notice, 
                  pay to Freeport an amount which shall be specified in such 
                  notice from Freeport and equal to the difference between 
                  (i) the total amount Freeport would otherwise have 
                  recovered through the Facilities Charge in accordance with 
                  the depreciation schedule applicable to such Early 
                  Termination Facility) during the period beginning on the 
                  Commencement Date and ending as of the tenth anniversary of 
                  the Commencement Date, for Felmont's proportionate share 
                  (determined as provided in Section 10.3) of the cost of 
                  such Early Termination Facility after taking into account 
                  amounts to be paid by Felmont as a Facilities Fee with 
                  respect to such a Facility during the Purchase Requirement 
                  Period (including the Reasonable Cost of Capital associated 
                  therewith), and (ii) the portion, if any, of such total 
                  amount which shall have been recovered by Freeport through 
                  the Facilities Charge and any adjustments to the Facilities 
                  Charge pursuant to Section 10.3 as of the date of 
                  termination. Upon making such payment, Felmont shall, 
                  except as provided in the next following sentence, 
                  thereafter be relieved of all further financial 
                  responsibility for and right to surplus proceeds from such 
                  Early Termination Facility. If after having received such 
                  payment from Felmont as aforesaid, Freeport should choose 
                  to scrap or sell such Early Termination Facility, as the 
                  case may be, and such scrapping or sale entails a Closure 
                  Cost, Felmont shall bear its proportionate share of such 
                  Closure Cost. Felmont's proportionate share of such Closure 
                  Cost shall be determined in the manner provided in Section 
                  10.6.1 above for the period of time when this Agreement was 
                  in effect, and 

                                  20

<PAGE>

               Felmont shall have no responsibility for any portion of such 
               Closure Cost relating to utilization of such Early Termination 
               Facility before or after that period of time.

       10.6.5  Should Freeport sell or otherwise permanently dispose of a 
               Facility to a Freeport Related Party, for all purposes of this 
               Agreement, Freeport shall be deemed to have received the fair 
               market value of such Facility after taking into account all 
               relevant matters as agreed by the parties or if they fail to 
               agree as determined by appraisal. If the parties fail to agree 
               and such value is to be fixed by appraisal, each party shall 
               select an appraiser who is familiar with the valuation of 
               similar assets and operations. The two appraisers so selected 
               shall choose a third similarly qualified appraiser. The three 
               appraisers shall simultaneously submit their appraisals with a 
               brief statement of the basis therefor. The appraised value 
               shall be the average of the two appraisals which are closest 
               to each other unless such value is determined to be clearly 
               unreasonable.

   10.7  APPROVAL LEVEL ADJUSTMENT PROCEDURE.  The dollar amounts associated 
         with Felmont's rights to approve capital expenditures specified in 
         Sections 10.2 and 10.3 hereof shall be adjusted annually commencing 
         on December 31, 1990 and on each December 31 thereafter by 
         multiplying such dollar amount by the percentage change in the 
         "Implicit Price Deflator for Gross National Product (Index number 
         1982 = 00)" as published by the Bureau of Economic Analysis of the 
         United States Department of Commerce in the monthly publication 
         "Survey of Current Business" for the second calendar quarter 
         (seasonally adjusted) if the year in which the adjustment is made 
         form a base of 125.9. For example, assuming an increase in the index 
         of 10% from the base of 125.9, each of the dollar amounts specified 
         in Sections 10.2 and 10.3 hereof shall be increased 10%. Should the 
         index specified above cease to be published at any time during the 
         term of this Agreement, the parties shall select a substitute index 
         which in their judgement as nearly as possible approximates the 
         results obtained by use of the index specified above.

   10.8  ESTIMATE OF CLOSURE COST; PREPAYMENT. Should Freeport in its 
         direction choose to continue to use a Facility exclusively for 
         purposes other than performing the services pursuant to this 
         Agreement after termination of this Agreement, Freeport shall 
         promptly so notify Felmont. Felmont shall have the right to require 
         Freeport to prepare an estimate of Closure Cost for such Facility 
         and to calculate the present value of such Closure Cost using the 
         publicly announced fluctuating prime rate of interest then in effect 
         charged by Chase Manhattan Bank, New York, New York, on 90-day loans 
         to its most responsible and substantial customers, plus 2% (but in no 
         event in excess of the maximum rate of interest which it is permitted 
         to charge from time to time under applicable law), and shall 
         reimburse Freeport for the costs reasonably incurred by Freeport in 
         preparing such estimate (except that if a third party jointly with 
         Felmont directs the preparation of such estimate, reimbursement to 
         Freeport of such preparation costs shall be borne between Felmont and 
         such third party in the proportion the respective interests of Felmont
         and such third

                                       21

<PAGE>

party in sulphur production from the Main Pass Mine bear to each other). 
Within 90 days after receipt of such estimate, Felmont shall have the right 
to pay Felmont's proportionate share of such present value of such estimated 
Closure Cost and upon Freeport's receipt of such amount Felmont shall have no 
further obligation, express or implied, to Freeport for Closure Cost for such 
Facility.

                 XI.  ADDITIONAL CAPITAL DISPUTE RESOLUTION

     In then event of the failure of the chief executive officers of Felmont's 
ultimate parent and Freeport's ultimate parent to leach a decision on a 
matter referred to them pursuant to Section 10.4 hereof by the end of the 30 
day period provided for therein, the matter shall be determined through the 
"Baseball Arbitration" procedure described hereinafter in this Article XI and 
such determination shall be binding on the parties

   11.1  Within 20 days after the expiration of the 30 day period referred to 
         above, Felmont and Freeport shall simultaneously exchange a written 
         statement of their respective positions as to the matter in dispute, 
         which statement shall be limited to 10 single spaced typewritten 
         pages plus supporting documentation.

   11.2  On or before the fifth day after the exchange of statements under 
         Section 11.1 above, each party must name its choice of an arbitrator. 
         Within 20 days thereafter, the two arbitrators so chosen shall name a 
         third arbitrator. If any of the three arbitrators has not been named 
         within the appointed time, then either party may apply to the 
         American Arbitration Association for appointment of the arbitrator(s) 
         necessary to complete the panel within 20 days thereafter. All 
         arbitrators shall be individuals who are not and never have been 
         officers, directors or employees of either party or of any Related 
         Party, and who are not currently officers, directors or employees of 
         any supplier which by reason of the volume of business between the 
         party appointing such arbitrator and that supplier can reasonably be 
         expected to have a conflict of interest. All arbitrators shall be 
         qualified by education, knowledge and experience to determine the 
         matters submitted to them. Each party shall each pay the compensation 
         and expenses of the arbitrators named by or for it, and both shall 
         share equally the compensation and expenses of the third arbitrator, 
         subject to reimbursement of the prevailing party as provided in 
         Section 11.3 below. Within 30 days following the date that a 
         three-person panel is established, the three arbitrators shall 
         evaluate the statements of each party and select a position which 
         must be either the Felmont position set forth in its statement or the 
         Freeport position set forth in its statement. The decision cannot be 
         one that creates an alternative position other than those set forth 
         in the parties' statements. The decision of the arbitration panel, or 
         a majority thereof, shall be final and binding as to the matters 
         submitted for arbitration by the parties. Notwithstanding anything in 
         this Agreement, or any decision rendered pursuant to this Article XI, 
         to the contrary, Freeport reserves the right at all times to proceed 
         in its sole discretion with any

                                     22
<PAGE>

         capital expenditure for its own use and for its own account, and 
         the only effect of Felmont's approval or disapproval of a capital 
         expenditure will be whether such capital expenditure shall be 
         utilized by Freeport in performing services under this Agreement and 
         whether Felmont has an obligation to pay a Facilities Charge 
         associated therewith.

   11.3  The party whose position is selected by the arbitration panel 
         pursuant to Section 11.2 above (the "prevailing party"), shall be 
         entitled to reimbursement from the other party of all costs and 
         expenses reasonably incurred by it as the result of preparing and 
         submitting the matter at issue to arbitration pursuant to this 
         Article XI (including but not limited to reasonable attorneys fees 
         and all amounts paid pursuant to Section 11.2 above) within 30 days 
         after its submission of a statement of such costs and expenses to the 
         other party for payment, and the other party shall pay all other 
         costs and expenses of such arbitration over and above those incurred 
         by the prevailing party.

   11.4  Felmont understands that Freeport is also entering into a similar 
         agreement with IMCF concerning cervices to be performed by Freeport 
         in connection with Main Pass sulphur produced for IMCF's account. 
         In the event that Freeport proposes a capital expenditure that is 
         subject to the approval of both Felmont and IMCF and neither 
         approves, and the chief executive officers of Freeport, Felmont and 
         IMCF are unable to reach a decision on such capital expenditure, 
         then, in order to avoid the potential of inconsistent results, 
         Freeport and Felmont agree that the arbitration of such dispute 
         shall be conducted in a single proceeding with Freeport, Felmont and 
         IMCF all participating in that single proceeding. In the event of 
         such a three party arbitration, the procedures provided in Section 
         11.2 shall govern but Freeport, individually, and Felmont and IMCF, 
         collectively, shall have the right to name an arbitrator and the two 
         arbitrators so named shall name three additional arbitrators. If the 
         panel has not been completed within the time contemplated above, any 
         party may apply to the American Arbitration Association to complete 
         the panel. The arbitrators shall select the position of one of the 
         three parties. Each party of the arbitration shall simultaneously 
         exchange a written statement of its respective position as to the 
         matters in dispute. The prevailing party's expenses shall be borne 
         by the other two parties in the proportion that their respective 
         interests in sulphur production from the Main Pass Mine bear to each 
         other. Agreement by Freeport and IMCF or Felmont and IMCF on any 
         such matter shall not preclude the exercise by the other party 
         hereto of its right to arbitrate under Section 11.1 through Section 
         11.3.

                               XII.  WARRANTIES

     12.1  TITLE. Felmont warrants title to all Felmont Sulphur received by 
Freeport from Felmont hereunder free from all liens encumbrances, taxes or 
claims arising by, through or under Felmont. Freeport warrants title to all 
Felmont Blending Sulphur.

     12.2  WARRANTY OBLIGATION. Under current conditions in the sulphur 
market, Freeport markets sulphur to purchasers on the basis that sulphur 
delivered will confirm to written specifications agreed to between Freeport 
and its sulphur purchasers with price allowances for sulphur not meeting such 
specifications and on the basis that Freeport shall not be liable for 
indirect or consequential damages including loss of revenues or loss of 
profits. Freeport otherwise makes no express warranties nor does it disclaim 
any warranties. Felmont warrants Felmont Sulphur to Freeport to the extent 
required to permit Freeport to market Combined Sulphur on the basis above 
described. Should Freeport find it necessary in order to market Combined 
Sulphur at any time or from time to time during the term of this Agreement to 
accept terms and conditions different than described above, Freeport shall so 
notify Felmont and continue to market Combined Sulphur in accordance with 
this Agreement unless Felmont should choose to terminate this Agreement as the 
result of such notification. Felmont agrees that from and after any such 
notification from Freeport, Felmont shall warrant Felmont Sulphur to the 
extent necessary to permit Freeport to market Combined Sulphur on the basis 
of such revised terms and conditions described in such notice.

                            XIII. SALES AGENCY

     13.1  EXCLUSIVE AGENT. As sales agent for Felmont, Freeport will sell 
the Felmont Sulphur in exclusively Freeport's name and will be the sole and 
exclusive seller of Felmont Sulphur during the time this Agreement is in 
force and effect but will have no actual or apparent authority to make 
commitments on Felmont's behalf except with respect to Felmont Sulphur to 
be sold and delivered under the terms of this Agreement.

     13.2  DETERMINATION AND PAYMENT OF SALES PROCEEDS DUE FELMONT. Of the 
Combined Sulphur determined by Freeport to have been sold during a month, the 
portion thereof which is Felmont Tonnage shall be determined in the manner 
prescribed in Schedule C hereof. Within 45 days after the end of a month 
Freeport will remit to Felmont an amount equal to the Felmont Tonnage 
multiplied by the per-ton Average Sales Realization for the month less the per 
ton Marketing Fee applicable to such month, and Freeport agrees to pay 
Felmont a service charge equal to the lesser of (i) 0.05% per day 
(approximately one and one-half percent (1-1/2%) per month), or (ii) the 
highest percentage interest rate then permitted by law, on all remittances 
due from Freeport not received by Felmont on or before the date due.

    13.3  INVENTORY REMAINING ON TERMINATION. In the event that this Agreement 
terminates and Freeport has not remitted to Felmont the sales proceeds due 
Felmont for any quantities of

                                     24

<PAGE>

Felmont Sulphur previously received by Freeport other than Requirement Period 
Sales Tonnage, the provisions of this Article XIII and the allocation 
procedures of Schedule C shall continue to apply to such Felmont Sulphur until 
Felmont has received payment: in full therefor.

                XIV. TERMINATION PURCHASE REQUIREMENT

     Should Felmont give notice of termination pursuant to Article IV hereof, 
then upon and notwithstanding such termination, except as otherwise provided 
in Section 4.3 hereof, Freeport shall be obligated to purchase from Felmont 
and Felmont shall be obligated to sell to Freeport all Felmont Main Pass 
Sulphur produced at the Main Pass Mine during the period beginning on the 
date of termination of the sales agency and ending as of December 31 of the 
year next following the year during which the sales agency terminated (such 
purchase and sale obligations as described in more detail hereinafter in this 
Article XIV being herein referred to as the "Termination Purchase 
Requirement" and such period being hereinafter referred to as the "Purchase 
Requirement Period"). For each month of the Purchase Requirement Period 
Freeport shall determine the number of tons of Freeport Sulphur sold by 
Freeport to all customers during the month (such tonnage hereinafter called 
the "Requirement Period Sales Tonnage"). Freeport shall then calculate the 
Requirement Period Average Sales Realization for the month which shall be the 
average revenue per ton realized by Freeport from sale to customers 
(excluding sales to Freeport and Freeport Related Parties) of the Requirement 
Period Sales Tonnage (excluding sales to Freeport and Freeport Related 
Parties) for such month, less the per ton average of all proper adjustments 
such as discounts and transfer-related taxes paid (but excluding sales to 
Freeport and Freeport Related Parties and excluding bad debt losses) in 
respect of the Requirement Period Sales Tonnage for such month. The Purchase 
Requirement Price payable for Felmont Main Pass Sulphur received by Freeport 
during the month shall be the Reimbursement Period Average Sales Realization 
for the month less the Requirement Period Charge for such month. As used 
herein the term "Requirement Period Charge" means the sum of the Operating 
Charge for the month plus the Facilities Fee plus the Requirement Discount 
for the month as those terms are defined hereinafter:

          (i)    OPERATING CHARGE. For each month of the Purchase Requirement 
                 Period Freeport shall determine an amount calculated in the 
                 same manner as the Operating Cost Reimbursement but excluding
                 any vatting and melting costs. Such amount shall by multiplied
                 by 105% and the product thereof divided by the number of tons 
                 of Felmont Main Pass Sulphur received by Freeport during such 
                 month. The amount thus obtained shall be the Operating Charge 
                 for such month.

         (ii)    FACILITIES FEE. The Facilities Fee shall be an amount per ton 
                 equal to the Facilities Charge in effect at the time of 
                 termination of the agreement. Appropriate credit shall be 
                 made by Freeport for any pre-payment of the Facilities Charge 
                 made prior to Termination.

                                      25

<PAGE>


        (iii)    REQUIREMENT DISCOUNT. The Requirement Discount for any month 
                 of the Purchase Requirement Period shall be an amount equal 
                 to 5% of the Requirement Period Average Sales Realization 
                 for such month.


Payment for the total tonnage of Felmont Main Pass Sulphur received by 
Freeport during a particular month shall be made by Freeport to Felmont 
within 45 days after the end of such month. Title and risk of loss shall pass 
to Freeport at the Receiving Point.

                       XV. TITLE: RISK OF LOSS

     Title to Felmont Sulphur shall pass to Freeport at the shoreline flange 
at the Port Sulphur Terminal as the Felmont Sulphur is progressively 
discharged into such Facility from the transportation equipment transporting 
such sulphur from the Main Pass Mine to such terminal; provided, however, 
that if the sulphur produced from the Main Pass Mine is transported to a 
Receiving Point other than the Port Sulphur Terminal, the title to Felmont 
Sulphur shall pass to Freeport at the flange of the vessel transporting such 
sulphur from the Main Pass Mine to such other location. Risk of loss of 
Felmont Sulphur shall remain in Felmont until delivery thereof to a purchaser, 
except as may be otherwise provided in Article VII hereof.

                 Facilities, the replacement cost thereof; provided, however, 
                 that Freeport shall credit the amount of any recovery under 
                 such property insurance to the cost of repair or replacement 
                 of the Facility damaged.

       16.1.16   With respect to all of the above insurance, Freeport shall 
                 furnish Felmont with Certificates of Insurance evidencing 
                 the issuing of the required policies and that they are in 
                 force and stating such policies will not be canceled or

annual renewal of Freeport's blanket All Risk Property Insurance and Cargo 
Insurance programs, Freeport shall advise Felmont of the principal provisions 
thereof, including deductibles and premium. Within fifteen days after receipt 
of such information from Freeport, Felmont shall advise Freeport whether, for

proportionate share of the actual amount recovered under Freeport's insurance 
after any deductible has been proportionately applied, (ii) to carry its own 
insurance on Felmont Sulphur, or (iii) to self insure Felmont Sulphur. In any 
event Felmont hereby waives, on behalf of itself and any of its insurers, any 
right of recovery or subrogation against Freeport in the event of a loss of 
Felmont Sulphur, and each insurance policy shall be so endorsed.

     16.3  INDEMNITY. Each party hereby agrees to indemnify and hold harmless 
the other party, its Related Parties, and their officers, directors and 
employees, from and against any claim for bodily injury or property damage

certified public accountants which is deemed to be confidential by Freeport 
(including, but not limited to, corporate minutes and unitholder records) 
shall not be disclosed to Felmont by such designated firm of certified public

                  1997 STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS

         The purpose of the 1997 Stock Option Plan for Non-Employee Directors
(the "Plan") is to align more closely the interests of the non-employee
directors of Freeport-McMoRan Sulphur Inc. (the "Company")  with that of the
Company's stockholders by providing for the automatic grant to such directors of
stock options ("Options") to purchase Shares (as hereinafter defined), in
accordance with the terms of the Plan.


                                      ARTICLE II
                                           
                                     DEFINITIONS

meanings indicated:

         BOARD:  The Board of Directors of the Company.

         CHANGE IN CONTROL:  A Change in Control shall be deemed to have
occurred if either (a) any person, or any two or more persons acting as a group,
and all affiliates of such person or persons, shall own beneficially more than
20% of the Common Stock outstanding (exclusive of shares held in the Company's
treasury or by the Company's Subsidiaries) pursuant to a tender offer, exchange
offer or series of purchases or other acquisitions, or any combination of those
transactions, or (b) there shall be a change in the composition of the Board at
any time within two years after any tender offer, exchange offer, merger,
consolidation, sale of assets or contested election, or any combination of those
transactions (a "Transaction"), so that (i) the persons who were directors of
the Company immediately before the first such Transaction cease to constitute a
majority of the Board of Directors of the corporation which shall thereafter be

Transaction, or (ii) the number of persons who shall thereafter be directors of
such corporation shall be fewer than two-thirds of the number of directors of
the Company immediately prior to such first Transaction.  A Change in Control

the foregoing clauses (a) and (b).

         CODE:  The Internal Revenue Code of 1986, as amended from time to

date, on the last preceding date on which any reported sale occurred) on the
principal exchange or market on which such Shares are quoted.

         OPTION CANCELLATION GAIN:  With respect to the cancellation of an
Option pursuant to Section 3 of Article IV hereof, the excess of the Fair Market
Value as of the Option Cancellation Date (as that term is defined in Section 3

whether or not then exercisable, over the purchase price of such Shares under
such Option.

or regulation thereto as in effect from time to time.

of equity securities or interests of such entity are owned, directly or

                                     ARTICLE III
                                           
                              ADMINISTRATION OF THE PLAN
                                           
         This Plan shall be administered by the Board.  The Board will
interpret this Plan and may from time to time adopt such rules and regulations
for carrying out the terms and provisions of this Plan as it may deem best. 
Notwithstanding the foregoing, the Committee shall have the authority to make
all determinations with respect to the transferability of Options in accordance
with Article VIII hereof.  All determinations by the Board or the Committee
shall be made by the affirmative vote of a majority of its respective members,
but any determination reduced to writing and signed by a majority of its
respective members shall be fully as effective as if it had been made 

                                      -2-

<PAGE>

by a majority vote at a meeting duly called and held. Subject to any applicable
provisions of the Company's By-Laws or of this Plan, all determinations by the
Board and the Committee pursuant to the provisions of this Plan, and all related
orders or resolutions of the Board and the Committee, shall be final, conclusive
and binding on all persons, including the Company and its stockholders,
employees, directors and optionees.  In the event of any conflict or
inconsistency between determinations, orders, resolutions, or other actions of
the Committee and the Board taken in connection with this Plan, the action of
the Board shall control.  


                                      ARTICLE IV
                                           
                              STOCK SUBJECT TO THE PLAN
                                           
         SECTION 1.  The Shares to be issued or delivered upon exercise of
Options shall be made available, at the discretion of the Board, either from the
authorized but unissued Shares of the Company or from Shares reacquired by the
Company, including Shares purchased by the Company in the open market or
otherwise obtained.

         SECTION 2.  Subject to the provisions of Section 3 of this Article IV,
the aggregate number of Shares which may be purchased pursuant to Options shall
not exceed 75,000.  To the extent an Option is forfeited or cancelled prior to
exercise, the Shares subject to such forfeited or cancelled Option shall again
be available for grant under the Plan.  To the extent that Shares are delivered
to pay the exercise price of an Option, the number of Shares so delivered shall
again be available for grant under the Plan.

         SECTION 3.  In the event that the Board determines that any dividend
or other distribution (whether in the form of cash, Shares, Subsidiary
securities, other securities or other property), recapitalization, stock split,
reverse stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase or exchange of Shares or other securities of the
Company, issuance of warrants or other rights to purchase Shares or other
securities of the Company, or other similar corporate transaction or event
affects the Shares such that an adjustment is determined by the Board to be
appropriate to prevent dilution or enlargement of the benefits or potential
benefits intended to be made available under the Plan, then the Board may, in
its sole discretion and in such manner as it may deem equitable, adjust any or
all of (i) the number and type of Shares (or other securities or property) with
respect to which Options may be granted, (ii) the number and type of Shares (or
other securities or property) subject to outstanding Options, and (iii) the
grant or exercise price with respect to any Option and, if deemed appropriate,
make provision for a cash payment to the holder of an outstanding Option,
PROVIDED that the number of Shares subject to any Option shall always be a whole
number.

         SECTION 4.  In the event the Company is merged or consolidated into or
with another corporation in a transaction in which the Company is not the
survivor, or in the event that substantially all of the Company's assets are
sold to another entity not affiliated with the Company, any holder of an Option,
whether or not then exercisable, shall be entitled to receive (unless the
Company shall take such alternative action as may be necessary to preserve the
economic benefit 

                                      -3-

<PAGE>

of the Option for the optionee) on the effective date of any
such transaction (the "Option Cancellation Date"), in cancellation of such
Option, an amount in cash equal to the Option Cancellation Gain relating
thereto, determined as of the Option Cancellation Date.


                                      ARTICLE V

         The purchase price per Share under each Option shall be 100% of the
Fair Market Value of a Share at the time such Option is granted, but in no case
shall such price be less than the par value of the Shares subject to such
Option.


                                      ARTICLE VI
                                           
                              ELIGIBILITY OF RECIPIENTS

                                   GRANT OF OPTIONS
                                           
         SECTION 1.  Each Option shall constitute a nonqualified stock option
which is not intended to qualify under Section 422 of the Code.

         SECTION 2.  Effective upon the distribution of shares to shareholders
of Freeport-McMoRan Inc. ("FTX") under the Contribution and Distribution
Agreement dated August 26, 1997 among FTX, Freeport-McMoRan Resource Partners
and the Company, each Eligible Director shall be granted an Option to purchase
5,000 Shares.  On May 1, 1998  and May 1 of each subsequent year that the Plan
remains in effect, each Eligible Director, as of each such date, shall be
granted an Option to purchase 1,000 Shares.

         SECTION 3.  Each Option shall become exercisable with respect to
one-fourth of the Shares subject thereto on each of the first, second, third and
fourth anniversaries of the date of grant and may be exercised by the holder
thereof with respect to all or any part of the Shares comprising each
installment as such holder may elect at any time after such installment becomes
exercisable but no later than the termination date of such Option; provided that
each Option shall become exercisable in full upon a Change in Control.

         SECTION 4.  The purchase price of Shares subject to any Option shall
be the Fair Market Value thereof on the respective date of grant.

         No Options granted hereunder may be transferred, pledged, assigned or
otherwise encumbered by an optionee except:

         (a)  by will;

         (b)  by the laws of descent and distribution; or

         (c)  if permitted by the Committee and so provided in the Option or an
    amendment thereto, (i) pursuant to a domestic relations order, as defined
    in the Code, (ii) to Immediate Family Members, (iii) to a partnership in
    which Immediate Family Members, or entities in which Immediate Family
    Members are the owners, members or beneficiaries, as appropriate, are the
    partners, (iv) to a limited liability company in which Immediate Family
    Members, or entities in which Immediate Family Members are the owners,
    members or beneficiaries, as appropriate, are the members, or (v) to a
    trust for the benefit of Immediate Family Members; provided, however, that
    no more than a DE MINIMUS beneficial interest in a partnership, limited
    liability company or trust described in (iii), (iv) or (v) above may be
    owned by a person who is not an Immediate Family Member or by an entity
    that is not beneficially owned solely by Immediate Family Members. 
    "Immediate Family Members" shall be defined as the spouse and natural or
    adopted children or grandchildren of the optionee and their spouses.

Any attempted assignment, transfer, pledge, hypothecation or other disposition
of Options, or levy of attachment or similar process upon Options not
specifically permitted herein, shall be null and void and without effect.


                                      ARTICLE IX

                                 EXERCISE OF OPTIONS

         SECTION 1.  Each Option shall terminate 10 years after the date on
which it was granted.

         SECTION 2.  Except in cases provided for in Article X hereof, each
Option may be exercised by the holder thereof only while the optionee to whom
such Option was granted is an Eligible Director.

         SECTION 3.  A person electing to exercise an Option or any portion
thereof then exercisable shall give written notice to the Company of such
election and of the number of Shares such person has elected to purchase, and
shall at the time of purchase tender the full purchase price 

                                      -5-

<PAGE>

of such Shares, which tender shall be made in cash or cash equivalent (which 
may be such person's personal check) or in Shares already owned by such 
person (which Shares shall be valued for such purpose on the basis of their 
Fair Market Value on the date of exercise), or in any combination thereof.  
The Company shall have no obligation to deliver Shares pursuant to the 
exercise of any Option, in whole or in part, until such payment in full of 
the purchase price of such Shares is received by the Company.  No optionee, 
or legal representative, legatee, distributee, or assignee of such optionee 
shall be or be deemed to be a holder of any Shares subject to such Option or 
entitled to any rights of a stockholder of the Company in respect of any 
Shares covered by such Option distributable in connection therewith until 
such Shares have been paid for in full and certificates for such Shares have 
been issued or delivered by the Company.

         SECTION 4.  Each Option shall be subject to the requirement that if at
any time the Board shall be advised by counsel that the listing, registration or
qualification of the Shares subject to such Option upon any securities exchange
or under any state or federal law, or the consent or approval of any
governmental regulatory body, is necessary or desirable as a condition of, or in
connection with, the granting of such Option or the issue or purchase of Shares
thereunder, such Option may not be exercised in whole or in part unless such
listing, registration, qualification, consent or approval shall have been
effected or obtained free from any conditions not reasonably acceptable to such
counsel for the Board.

         SECTION 5.  The Company may establish appropriate procedures to
provide for payment or withholding of such income or other taxes as may be
required by law to be paid or withheld in connection with the exercise of
Options, and to ensure that the Company receives prompt advice concerning the
occurrence of any event which may create, or affect the timing or amount of, any
obligation to pay or withhold any such taxes or which may make available to the
Company any tax deduction resulting from the occurrence of such event.

Director for any reason other than death or retirement from the Board, all of
the Options granted to such optionee  shall be terminated except that any
Option, to the extent then exercisable, may be exercised by the holder thereof
within three months after such optionee ceases to be an Eligible Director, but

         SECTION 2.  If and when an optionee shall cease to be an Eligible
Director by reason of the optionee's retirement from the Board, all of the
Options granted to such optionee shall be terminated except that any Option, to
the extent then exercisable or exercisable within one year thereafter, may be
exercised by the holder thereof within three years after such retirement, but
not later than the termination date of the Option.

         SECTION 3.  Should an optionee die while serving as an Eligible
Director, all the  Options granted to such optionee shall be terminated, except
that any Option to the extent exercisable by the holder thereof  at the time of
such death, together with the unmatured installment (if any) of such Option
which at that time is next scheduled to become exercisable, may be exercised
within one year after the date of such death, but not later than the termination
date of the Option, by the holder thereof, the optionee's estate, or the person
designated in the optionee's last will and testament, as appropriate.

         SECTION 4.  Should an optionee die after ceasing to be an Eligible
Director, all of the Options granted to such optionee shall be terminated,
except that any Option, to the extent exercisable by the holder thereof at the
time of such death, may be exercised within one year after the date of such
death, but not later than the termination date of the Option, by the holder
thereof, the optionee's estate, or the person designated in the optionee's last

         The Board may at any time terminate or from time to time amend, modify
or suspend this Plan; provided, however, that no such amendment or modification
shall be made without stockholder approval if such approval is deemed necessary
to comply with any regulatory requirements.

                                   SECTION 5

         (a) SHARES AVAILABLE FOR AWARDS.  Subject to adjustment as provided 
in Section 5(b):

                                     -3-
<PAGE>


              (i)  CALCULATION OF NUMBER OF SHARES AVAILABLE.   The number of 
    Shares with respect to which Awards may be granted under the Plan shall 
    be such number of Shares as results from the application of the award 
    formulas set forth in Sections 6 and 7.  If, after the effective date of 
    the Plan, an Award granted under the Plan expires or is exercised, 
    forfeited, canceled or terminated without the delivery of Shares, then 
    the Shares covered by such Award or to which such Award relates, or the 
    number of Shares otherwise counted against the aggregate number of 
    Shares with respect to which Awards may be granted, to the extent of any 
    such expiration, exercise, forfeiture, cancellation or termination, 
    shall not thereafter be available for grants or Awards under the Plan.

              (ii)  SOURCES OF SHARES DELIVERABLE UNDER AWARDS.  Any Shares
    delivered pursuant to an Award may consist of authorized and unissued Shares
    or of treasury Shares, including Shares held by the Company or a Subsidiary 
    and acquired in the open market or otherwise obtained by the Company or a
    Subsidiary.

              (iii)  INDIVIDUAL LIMIT.  Any provision of the Plan to the 
    contrary notwithstanding, no individual may receive in any year Awards under
    the Plan, whether payable in cash or Shares, that relate to more than 
    200,000 Shares.

         (b) ADJUSTMENTS.  In the event that the Committee determines that 
any dividend or other distribution (whether in the form of cash, Shares, 
Subsidiary securities, other securities or other property), recapitalization, 
stock split, reverse stock split, reorganization, merger, consolidation, 
split-up, spin-off, combination, repurchase or exchange of Shares or other 
securities of the Company, issuance of warrants or other rights to purchase 
Shares or other securities of the Company, or other similar corporate 
transaction or event affects the Shares such that an adjustment is determined 
by the Committee to be appropriate to prevent dilution or enlargement of the 
benefits or potential benefits intended to be made available under the Plan, 
then the Committee may, in its sole discretion and in such manner as it may 
deem equitable, adjust any or all of (i) the number and type of Shares (or 
other securities or property) with respect to which Awards may be granted, 
(ii) the number and type of Shares (or other securities or property) subject 
to outstanding Awards, and (iii) the grant or exercise price with respect to 
any Award or, if deemed appropriate, make provision for a cash payment to the 
holder of an outstanding Award; PROVIDED, that the number of Shares subject 
to any Award denominated in Shares shall always be a whole number.

                                 SECTION 6

         (a) STOCK OPTIONS.  Immediately prior to the Distribution, each 
holder of an FTX Award shall receive an Option to purchase such number of 
Shares (disregarding any fractional Share) as such holder would be eligible 
to receive in the Distribution with respect to the number of shares of FTX 
common stock subject to such FTX Award if such holder were the owner of 
record of such FTX shares on the record date for the Distribution.  Except as 
set forth in Sections 6(b) and 6(c), each such Option shall have the same 
remaining term and other terms and conditions (whether such terms and 
conditions are contained in the related FTX Award agreement or in the plan 
under which such FTX Award was made) and shall be immediately exercisable in 
full, as were the FTX 

                                     -4-
<PAGE>


Awards from which they were derived as a result of the change of control of 
FTX, with such changes and modifications as are necessary to substitute the 
Company for FTX as the issuer of the Option.

         (b) EXERCISE PRICE.  The per Share exercise price of each Option 
granted pursuant to Section 6(a) shall be the per share exercise price or 
grant price of the FTX Award from which such Option was derived multiplied by 
a fraction, the numerator of which is the "Company Distribution Value," as 
defined below, and the denominator of which is the "FTX Distribution Value," 
as defined below.  For purposes of this Section 6(b), the "Company 
Distribution Value" shall be the weighted average per Share price of the 
Shares on the New York Stock Exchange on the first day that Shares are traded 
on the New York Stock Exchange after the effective date of the Merger, and 
the FTX Distribution Value shall be the weighted average per share price of 
the FTX common stock on the New York Stock Exchange on the last day that 
shares of FTX common stock are traded on the New York Stock Exchange before 
the effective date of the Merger.

         (c) TAX-OFFSET RIGHT ADJUSTMENT.  Notwithstanding the foregoing, if 
the FTX Option from which the Option granted under this Section 6 derives 
contained a right to receive a cash payment upon exercise of such FTX Option 
related to and intended to defray the income tax liability associated 
therewith, the number of Shares to be subject to the Option, determined 
according to the provisions of Section 6(a) (without disregarding fractional 
Shares), shall be multiplied by 1.6556 and any fractional Share resulting 
from such adjustment shall be disregarded.  Such adjustment shall not affect 
the calculation of the per Share exercise price of the Option as set forth in 
Section 6(b).

         (d) PAYMENT.  No Shares shall be delivered pursuant to any exercise 
of an Option until payment in full of the option price therefor is received 
by the Company. Such payment may be made in cash, or its equivalent, or, if 
and to the extent permitted by the Committee, by applying cash amounts 
payable by the Company upon the exercise of such Option or other Awards by 
the holder thereof or by exchanging whole Shares owned by such holder (which 
are not the subject of any pledge or other security interest), or by a 
combination of the foregoing, provided that the combined value of all cash, 
cash equivalents, cash amounts so payable by the Company upon exercises of 
Awards and the fair market value of any such whole Shares so tendered to the 
Company, valued (in accordance with procedures established by the Committee) 
as of the effective date of such exercise, is at least equal to such option 
price.

                                 SECTION 7

         (a) LIMITED RIGHTS.  Each holder of an FTX Award shall receive, at 
the same time as and in tandem with each Option granted to such holder under 
Section 6, Limited Rights equal in number to the number of Shares subject to 
such Option with which such Limited Rights are in tandem.  Such Limited 
Rights shall have a grant price equal to the exercise price of the Option 
under Section 6 with which it is in tandem, and shall in all other respects 
contain the same terms and conditions as the agreement pertaining to the FTX 
Award from which they derived.

         (b) A Limited Right shall entitle the holder thereof to receive an 
amount equal to the excess, if any, of the Offer Price on the date of 
exercise of the Limited Right over the grant price.  

                                     -5-
<PAGE>


Any Limited Right may be settled in cash, Shares or a combination of cash and 
Shares, as determined by the Committee or the Board at the time of exercise, 
and shall only be exercisable during a period beginning not earlier than one 
day and ending not more than ninety days after the expiration date of an 
Offer.

                                  SECTION 8

         (a) AMENDMENTS TO THE PLAN.  The Board may amend, suspend or 
terminate the Plan or any portion thereof at any time, provided that no 
amendment shall be made without stockholder approval if such approval is 
necessary to comply with any tax or regulatory requirement, including for 
these purposes any approval necessary to qualify Awards as "performance 
based" compensation under Section 162(m) or any successor provision if such 
qualification is deemed necessary or desirable by the Committee.   
Notwithstanding anything to the contrary contained herein, (i) the Committee 
may amend the Plan in such manner as may be necessary for the Plan to conform 
with local rules and regulations in any jurisdiction outside the United 
States and (ii) any amendment, suspension or termination made in accordance 
with this Section 8(a) that would adversely affect a holder's rights under an 
Award made under the Plan may not be made without such holder's consent.

         (b) AMENDMENTS TO AWARDS.  The Committee may amend, modify or 
terminate any outstanding Award with the holder's consent at any time prior 
to payment or exercise in any manner not inconsistent with the terms of the 
Plan, including without limitation, a change in the date or dates as of which 
an Award becomes exercisable.

         (c) ADJUSTMENT OF AWARDS UPON THE OCCURRENCE OF CERTAIN UNUSUAL OR 
NONRECURRING EVENTS.  The Committee is hereby authorized to make adjustments 
in the terms and conditions of, and the criteria included in, Awards in 
recognition of unusual or nonrecurring events (including, without limitation, 
the events described in Section 5(b) hereof) affecting the Company, or the 
financial statements of the Company or any Subsidiary, or of changes in 
applicable laws, regulations, or accounting principles, whenever the 
Committee determines that such adjustments are appropriate to prevent 
dilution or enlargement of the benefits or potential benefits intended to be 
made available under the Plan.

         (d) CANCELLATION.  Any provision of this Plan or any Award Agreement 
to the contrary notwithstanding, the Committee may cause any Award granted 
hereunder to be canceled in consideration of a cash payment or alternative 
Award made to the holder of such canceled Award equal in value to such 
canceled Award.  The determinations of value under this subsection shall be 
made by the Committee in its sole discretion.

                                 SECTION 9

         (a) AWARD AGREEMENTS.  Each Award hereunder shall be evidenced by a 
writing delivered to the Participant that shall specify the terms and 
conditions thereof and any rules applicable thereto and that shall, in 
accordance with the provisions of the Plan, replicate as closely 

                                     -6-
<PAGE>


as possible the terms, conditions and other contractual attributes of the FTX 
Award from which the Award is derived, as in effect on the Distribution Date.

         (b) WITHHOLDING.   (i)  A Participant may be required to pay to the 
Company, and the Company shall have the right to deduct from all amounts paid 
to a Participant (whether under the Plan or otherwise), any taxes required by 
law to be paid or withheld in respect of Awards hereunder to such 
Participant. 

              (ii)  At any time that a Participant is required to pay to the 
Company an amount required to be withheld under the applicable tax laws in 
connection with the issuance of Shares under the Plan, the Participant may, 
if permitted by the Committee, satisfy this obligation in whole or in part by 
electing (the "Election") that the Company withhold from the issuance Shares 
having a value equal to the amount required to be withheld.  The value of the 
Shares withheld shall be based on the fair market value of the Shares on the 
date that the amount of tax to be withheld shall be determined in accordance 
with applicable tax laws (the "Tax Date").

              (iii)  Each Election must be made prior to the Tax Date.  The 
Committee may suspend or terminate the right to make Elections at any time.

              (iv)  A Participant may also satisfy his total tax liability 
related to the Award by delivering Shares owned by the Participant.  The 
value of the Shares delivered shall be based on the fair market value of the 
Shares on the Tax Date. 

         (c) TRANSFERABILITY.  No Awards granted hereunder may be 
transferred, pledged, assigned or otherwise encumbered by a Participant 
except: (i) by will; (ii) by the laws of descent and distribution; (iii) 
pursuant to a domestic relations order, as defined in the Code, if permitted 
by the Committee and so provided in the Award Agreement or an amendment 
thereto; or (iv) if permitted by the Committee and so provided in the Award 
Agreement or an amendment thereto, (a) to Immediate Family Members, (b) to a 
partnership in which Immediate Family Members, or entities in which Immediate 
Family Members are the owners, members or beneficiaries, as appropriate, are 
the partners, (c) to a limited liability company in which Immediate Family 
Members, or entities in which Immediate Family Members are the owners, 
members or beneficiaries, as appropriate, are the members, or (d) to a trust 
for the benefit of Immediate Family Members; provided, however, that no more 
than a DE MINIMUS beneficial interest in a partnership, limited liability 
company or trust described in (b), (c) or (d) above may be owned by a person 
who is not an Immediate Family Member or by an entity that is not 
beneficially owned solely by Immediate Family Members. "Immediate Family 
Members" shall be defined as the spouse and natural or adopted children or 
grandchildren of the Participant and their spouses.  Any attempted 
assignment, transfer, pledge, hypothecation or other disposition of Awards, 
or levy of attachment or similar process upon Awards not specifically 
permitted herein, shall be null and void and without effect.  The designation 
of a Designated Beneficiary shall not be a violation of this Section 9(c).

         (d) SHARE CERTIFICATES.  All certificates for Shares or other 
securities delivered under the Plan pursuant to any Award or the exercise 
thereof shall be subject to such stop transfer orders and other restrictions 
as the Committee may deem advisable under the Plan or the rules, regulations, 

                                     -7-
<PAGE>


and other requirements of the SEC, any stock exchange upon which such Shares 
or other securities are then listed, and any applicable federal or state 
laws, and the Committee may cause a legend or legends to be put on any such 
certificates to make appropriate reference to such restrictions.

         (e) NO LIMIT ON OTHER COMPENSATION ARRANGEMENTS.   Nothing contained 
in the Plan shall prevent the Company from adopting or continuing in effect 
other compensation arrangements, which may, but need not, provide for the 
grant of options and other types of Awards provided for hereunder (subject to 
stockholder approval of any such arrangement if approval is required), and 
such arrangements may be either generally applicable or applicable only in 
specific cases.

         (f) NO RIGHT TO EMPLOYMENT.  The grant of an Award shall not be 
construed as giving a Participant the right to be engaged or employed by or 
retained in the employ of FTX, the Company or any Subsidiary.  FTX, the 
Company or any Subsidiary may at any time dismiss a Participant from 
engagement or employment, free from any liability or any claim under the 
Plan, unless otherwise expressly provided in the Plan or in any Award 
Agreement or any agreement relating to the engagement or employment of the 
Participant by FTX, the Company or any Subsidiary.

         (g) GOVERNING LAW.  The validity, construction, and effect of the 
Plan, any rules and regulations relating to the Plan and any Award Agreement 
shall be determined in accordance with the laws of the State of Delaware.

         (h) SEVERABILITY.  If any provision of the Plan or any Award is or 
becomes or is deemed to be invalid, illegal, or unenforceable in any 
jurisdiction or as to any Person or Award, or would disqualify the Plan or 
any Award under any law deemed applicable by the Committee, such provision 
shall be construed or deemed amended to conform to applicable laws, or if it 
cannot be construed or deemed amended without, in the determination of the 
Committee, materially altering the intent of the Plan or the Award, such 
provision shall be stricken as to such jurisdiction, Person or Award and the 
remainder of the Plan and any such Award shall remain in full force and 
effect.

         (i) NO TRUST OR FUND CREATED.  Neither the Plan nor any Award shall 
create or be construed to create a trust or separate fund of any kind or a 
fiduciary relationship between the Company and a Participant or any other 
Person.  To the extent that any Person acquires a right to receive payments 
from the Company pursuant to an Award, such right shall be no greater than 
the right of any unsecured general creditor of the Company.

         (j) NO FRACTIONAL SHARES.  No fractional Shares shall be issued or 
delivered pursuant to the Plan or any Award, and the Committee shall 
determine, in accordance with the terms of the Plan, as applicable, whether 
cash, other securities or other property shall be paid or transferred in lieu 
of any fractional Shares or whether such fractional Shares or any rights 
thereto shall be canceled, terminated, or otherwise eliminated.

         (k) HEADINGS.  Headings are given to the subsections of the Plan 
solely as a convenience to facilitate reference.  Such headings shall not be 
deemed in any way material or relevant to the construction or interpretation 
of the Plan or any provision thereof.

dates, and the authority of the Committee to administer, interpret, amend, 
alter, adjust, suspend, discontinue, or terminate, in accordance with the 
provisions of the Plan, any such Award or to waive any conditions or rights 
under any such Award shall extend until the latest such date.

administration of the Plan; and (ix) make any other determination and take 
any other action that the Committee deems necessary or desirable for the

Participant, any holder or beneficiary of any Award, any stockholder of the 
Company and any Eligible Individual.

         (b)  DELEGATION.  Subject to the terms of the Plan and applicable

Award.


                                 SECTION 5

         (a)  SHARES AVAILABLE FOR AWARDS.  Subject to adjustment as provided 
in Section 5(b):

              (i)    CALCULATION OF NUMBER OF SHARES AVAILABLE.

                   (A)  The number of Shares with respect to which Awards 
payable in Shares may be granted under the Plan shall be 1,000,000, plus, to 
the extent authorized by the Board, the number of Shares reacquired by the 
Company in the open market or in private transactions for an aggregate price 
no greater than the cash proceeds received by the Company from the exercise 
of options granted under the Plan.  Awards that by their terms may be settled 
only in cash shall not be counted against the maximum number of Shares 
provided herein.

                   (B)  Grants of Stock Appreciation Rights, Limited Rights 
and Other Stock-Based Awards not granted in tandem with Options and payable 
only in cash may relate to no more than 1,000,000 Shares.  

                   (C)  Any Shares granted under the Plan that are forfeited 
because of failure to meet an Award contingency or condition shall again be 
available for grant pursuant to new Awards under the Plan.

                                     -4-
<PAGE>


                   (D)  To the extent any Shares covered by an Award are not 
issued because the Award is forfeited or cancelled or the Award is settled in 
cash, such Shares shall again be available for grant pursuant to new Awards 
under the Plan.

                   (E)  To the extent that Shares are delivered to pay the 
exercise price of an Option or are delivered or withheld by the Company in 
payment of the withholding taxes relating to an Award, the number of Shares 
so delivered or withheld shall become Shares with respect to which Awards may 
be granted.

              (ii)   SUBSTITUTE AWARDS.  Any Shares delivered by the Company, 
any Shares with respect to which Awards are made by the Company, or any 
Shares with respect to which the Company becomes obligated to make Awards, 
through the assumption of, or in substitution for, outstanding awards 
previously granted by an acquired company or a company with which the Company 
combines, shall not be counted against the Shares available for Awards under 
the Plan.

              (iii)  SOURCES OF SHARES DELIVERABLE UNDER AWARDS.  Any 
Shares delivered pursuant to an Award may consist of authorized and unissued 
Shares or of treasury Shares, including Shares held by the Company or a 
Subsidiary and Shares acquired in the open market or otherwise obtained by 
the Company or a Subsidiary.

              (iv)   INDIVIDUAL LIMIT.  Any provision of the Plan to the 
contrary notwithstanding, no individual may receive in any year Awards under 
the Plan, whether payable in cash or Shares, that relate to more than 200,000 
Shares.

         (b)  ADJUSTMENTS.  In the event that the Committee determines that 
any dividend or other distribution (whether in the form of cash, Shares, 
Subsidiary securities, other securities or other property), recapitalization, 
stock split, reverse stock split, reorganization, merger, consolidation, 
split-up, spin-off, combination, repurchase or exchange of Shares or other 
securities of the Company, issuance of warrants or other rights to purchase 
Shares or other securities of the Company, or other similar corporate 
transaction or event affects the Shares such that an adjustment is determined 
by the Committee to be appropriate to prevent dilution or enlargement of the 
benefits or potential benefits intended to be made available under the Plan, 
then the Committee may, in its sole discretion and in such manner as it may 
deem equitable, adjust any or all of (i) the number and type of Shares (or 
other securities or property) with respect to which Awards may be granted, 
(ii) the number and type of Shares (or other securities or property) subject 
to outstanding Awards, and (iii) the grant or exercise price with respect to 
any Award and, if deemed appropriate, make provision for a cash payment to 
the holder of an outstanding Award and, if deemed appropriate, adjust 
outstanding Awards to provide the rights contemplated by Section 9(b) hereof; 
PROVIDED, in each case, that with respect to Awards of Incentive Stock 
Options no such adjustment shall be authorized to the extent that such 
authority would cause the Plan to violate Section 422(b)(1) of the Code or 
any successor provision thereto and, with respect to all Awards under the 
Plan, no such adjustment shall be authorized to the extent that such 
authority would be inconsistent with the requirements for full deductibility 
under Section 162(m); and PROVIDED FURTHER, that the number of Shares subject 
to any Award denominated in Shares shall always be a whole number.

                                  SECTION 6

         (a)  STOCK OPTIONS.  Subject to the provisions of the Plan, the 
Committee shall have sole and complete authority to determine the Eligible 
Individuals to whom Options shall be granted, the number of Shares to be 
covered by each Option, the option price therefor and the conditions and 
limitations applicable to the exercise of the Option.  The Committee shall 
have the authority to grant Incentive Stock Options, Nonqualified Stock 
Options or both. In the case of Incentive Stock Options, the terms and 
conditions of such grants shall be subject to and comply with such rules as 
may be required by Section 422 of the Code, as from time to time amended, and 
any implementing regulations. Except in the case of an Option granted in 
assumption of or substitution for an outstanding award of a company acquired 
by the Company or with which the Company combines, the exercise price of any 
Option granted under this Plan shall not be less than 100% of the fair market 
value of the underlying Shares on the date of grant.

         (b)  EXERCISE.  Each Option shall be exercisable at such times and 
subject to such terms and conditions as the Committee may, in its sole 
discretion, specify in the applicable Award Agreement or thereafter, 
provided, however, that in no event may any Option granted hereunder be 
exercisable after the expiration of 10 years after the date of such grant.  
The Committee may impose such conditions with respect to the exercise of 
Options, including without limitation, any condition relating to the 
application of Federal or state securities laws, as it may deem necessary or 
advisable.

         (c)  PAYMENT.  No Shares shall be delivered pursuant to any exercise 
of an Option until payment in full of the option price therefor is received 
by the Company.  Such payment may be made in cash, or its equivalent, or, if 
and to the extent permitted by the Committee, by applying cash amounts 
payable by the Company upon the exercise of such Option or other Awards by 
the holder thereof or by exchanging whole Shares owned by such holder (which 
are not the subject of any pledge or other security interest), or by a 
combination of the foregoing, provided that the combined value of all cash, 
cash equivalents, cash amounts so payable by the Company upon exercises of 
Awards and the fair market value of any such whole Shares so tendered to the 
Company, valued (in accordance with procedures established by the Committee) 
as of the effective date of such exercise, is at least equal to such option 
price.


                                SECTION 7

         (a)  STOCK APPRECIATION RIGHTS.  Subject to the provisions of the 
Plan, the Committee shall have sole and complete authority to determine the 
Eligible Individuals to whom Stock Appreciation Rights shall be granted, the 
number of Shares to be covered by each Award of Stock Appreciation Rights, 
the grant price thereof and the conditions and limitations applicable to the 
exercise thereof.  Stock Appreciation Rights may be granted in tandem with 
another Award, in addition to another Award, or freestanding and unrelated to 
any other Award.  Stock Appreciation Rights granted in tandem with or in 
addition to an Option or other Award may be granted either at the same time 
as the Option or other Award or at a later time.  Stock Appreciation Rights 
shall not be exercisable after the expiration of 10 years after the date of 
grant. Except in the case of a Stock 

                                     -6-
<PAGE>


Appreciation Right granted in assumption of or substitution for an 
outstanding award of a company acquired by the Company or with which the 
Company combines, the grant price of any Stock Appreciation Right granted 
under this Plan shall not be less than 100% of the fair market value of the 
Shares covered by such Stock Appreciation Right on the date of grant or, in 
the case of a Stock Appreciation Right granted in tandem with a then 
outstanding Option or other Award, on the date of grant of such related 
Option or Award.

         (b)  A Stock Appreciation Right shall entitle the holder thereof to 
receive upon exercise, for each Share to which the SAR relates, an amount 
equal to the excess, if any, of the fair market value of a Share on the date 
of exercise of the Stock Appreciation Right over the grant price.  Any Stock 
Appreciation Right shall be settled in cash, unless the Committee shall 
determine at the time of grant of a Stock Appreciation Right that it shall or 
may be settled in cash, Shares or a combination of cash and Shares.


                                 SECTION 8

         (a)  LIMITED RIGHTS.  Subject to the provisions of the Plan, the 
Committee shall have sole and complete authority to determine the Eligible 
Individuals to whom Limited Rights shall be granted, the number of Shares to 
be covered by each Award of Limited Rights, the grant price thereof and the 
conditions and limitations applicable to the exercise thereof.  Limited 
Rights may be granted in tandem with another Award, in addition to another 
Award, or freestanding and unrelated to any Award.  Limited Rights granted in 
tandem with or in addition to an Award may be granted either at the same time 
as the Award or at a later time.  Limited Rights shall not be exercisable 
after the expiration of 10 years after the date of grant and shall only be 
exercisable during a period determined at the time of grant by the Committee 
beginning not earlier than one day and ending not more than ninety days after 
the expiration date of an Offer.  Except in the case of a Limited Right 
granted in assumption of or substitution for an outstanding award of a 
company acquired by the Company or with which the Company combines, the grant 
price of any Limited Right granted under this Plan shall not be less than 
100% of the fair market value of the Shares covered by such Limited Right on 
the date of grant or, in the case of a Limited Right granted in tandem with a 
then outstanding Option or other Award, on the date of grant of such related 
Option or Award.

         (b)  A Limited Right shall entitle the holder thereof to receive 
upon exercise, for each Share to which the Limited Right relates, an amount 
equal to the excess, if any, of the Offer Price on the date of exercise of 
the Limited Right over the grant price.  Any Limited Right shall be settled 
in cash, unless the Committee shall determine at the time of grant of a 
Limited Right that it shall or may be settled in cash, Shares or a 
combination of cash and Shares.


                                 SECTION 9

         (a)  OTHER STOCK-BASED AWARDS.  The Committee is hereby authorized 
to grant to Eligible Individuals an "Other Stock-Based Award", which shall 
consist of an Award, the value of 

                                     -7-
<PAGE>


which is based in whole or in part on the value of Shares, that is not an 
instrument or Award specified in Sections 6 through 8 of this Plan.  Other 
Stock-Based Awards may be awards of Shares or may be denominated or payable 
in, valued in whole or in part by reference to, or otherwise based on or 
related to, Shares (including, without limitation, securities convertible or 
exchangeable into or exercisable for Shares), as deemed by the Committee 
consistent with the purposes of the Plan.  The Committee shall determine the 
terms and conditions of any such Other Stock-Based Award and may provide that 
such awards would be payable in whole or in part in cash. Except in the case 
of an Other Stock-Based Award granted in assumption of or in substitution for 
an outstanding award of a company acquired by the Company or with which the 
Company combines, the price at which securities may be purchased pursuant to 
any Other Stock-Based Award granted under this Plan, or the provision, if 
any, of any such Award that is analogous to the purchase or exercise price, 
shall not be less than 100% of the fair market value of the securities to 
which such Award relates on the date of grant.

         (b)  DIVIDEND EQUIVALENTS.  In the sole and complete discretion of 
the Committee, an Award, whether made as an Other Stock-Based Award under 
this Section 9 or as an Award granted pursuant to Sections 6 through 8 
hereof, may provide the holder thereof with dividends or dividend 
equivalents, payable in cash, Shares, Subsidiary securities, other securities 
or other property on a current or deferred basis.


                                 SECTION 10

         (a)  AMENDMENTS TO THE PLAN.  The Board may amend, suspend or 
terminate the Plan or any portion thereof at any time, provided that no 
amendment shall be made without stockholder approval if such approval is 
necessary to comply with any tax or regulatory requirement, including for 
these purposes any approval necessary to qualify Awards as "performance 
based" compensation under Section 162(m) or any successor provision if such 
qualification is deemed necessary or advisable by the Committee. 
Notwithstanding anything to the contrary contained herein, the Committee may 
amend the Plan in such manner as may be necessary for the Plan to conform 
with local rules and regulations in any jurisdiction outside the United 
States.

         (b)  AMENDMENTS TO AWARDS.  The Committee may amend, modify or 
terminate any outstanding Award at any time prior to payment or exercise in 
any manner not inconsistent with the terms of the Plan, including without 
limitation, to change the date or dates as of which an Award becomes 
exercisable.  Notwithstanding the foregoing, no amendment, modification or 
termination may impair the rights of a holder of an Award under such Award 
without the consent of the holder.

         (c)  ADJUSTMENT OF AWARDS UPON THE OCCURRENCE OF CERTAIN UNUSUAL OR 
NONRECURRING EVENTS.  The Committee is hereby authorized to make adjustments 
in the terms and conditions of, and the criteria included in, Awards in 
recognition of unusual or nonrecurring events (including, without limitation, 
the events described in Section 5(b) hereof) affecting the Company, or the 
financial statements of the Company or any Subsidiary, or of changes in 
applicable laws, regulations, or accounting principles, whenever the 
Committee determines that such adjustments are 

                                     -8-
<PAGE>


appropriate to prevent dilution or enlargement of the benefits or potential 
benefits intended to be made available under the Plan.

         (d)  CANCELLATION.  Any provision of this Plan or any Award 
Agreement to the contrary notwithstanding, the Committee may cause any Award 
granted hereunder to be canceled in consideration of a cash payment or 
alternative Award made to the holder of such canceled Award equal in value to 
such canceled Award. The determinations of value under this subparagraph 
shall be made by the Committee in its sole discretion.


                                 SECTION 11

         (a)  AWARD AGREEMENTS.  Each Award hereunder shall be evidenced by a 
writing delivered to the Participant that shall specify the terms and 
conditions thereof and any rules applicable thereto, including but not 
limited to the effect on such Award of the death, retirement or other 
termination of employment of the Participant and the effect thereon, if any, 
of a change in control of the Company.

         (b)  WITHHOLDING. (i) A Participant may be required to pay to the 
Company, and the Company shall have the right to deduct from all amounts paid 
to a Participant (whether under the Plan or otherwise), any taxes required by 
law to be paid or withheld in respect of Awards hereunder to such 
Participant.  The Committee may provide for additional cash payments to 
holders of Awards to defray or offset any tax arising from the grant, 
vesting, exercise or payment of any Award.

              (ii)  At any time that a Participant is required to pay to the 
Company an amount required to be withheld under the applicable tax laws in 
connection with the issuance of shares of Common Stock under the Plan, the 
Participant may, if permitted by the Committee, satisfy this obligation in 
whole or in part by electing (the "Election") to have the Company withhold 
from the issuance shares of Common Stock having a value equal to the amount 
required to be withheld.  The value of the shares withheld shall be based on 
the fair market value of the Common Stock on the date that the amount of tax 
to be withheld shall be determined in accordance with applicable tax laws 
(the "Tax Date").

              (iii) Each Election must be made prior to the Tax Date.  The 
Committee may suspend or terminate the right to make Elections at any time.

              (iv)  A Participant may also satisfy his or her total tax 
liability related to the Award by delivering Shares owned by the Participant. 
The value of the Shares delivered shall be based on the fair market value of 
the Shares on the Tax Date.

         (c)  TRANSFERABILITY.  No Awards granted hereunder may be 
transferred, pledged, assigned or otherwise encumbered by a Participant 
except: (i) by will; (ii) by the laws of descent and distribution; (iii) 
pursuant to a domestic relations order, as defined in the Code, if permitted 
by the Committee and so provided in the Award Agreement or an amendment 
thereto; or (iv) if permitted 

                                     -9-
<PAGE>


by the Committee and so provided in the Award Agreement or an amendment 
thereto, Options and Limited Rights granted in tandem therewith may be 
transferred or assigned (a) to Immediate Family Members, (b) to a partnership 
in which Immediate Family Members, or entities in which Immediate Family 
Members are the owners, members or beneficiaries, as appropriate, are the 
partners, (c) to a limited liability company in which Immediate Family 
Members, or entities in which Immediate Family Members are the owners, 
members or beneficiaries, as appropriate, are the members, or (d) to a trust 
for the benefit of Immediate Family Members; provided, however, that no more 
than a DE MINIMUS beneficial interest in a partnership, limited liability 
company or trust described in (b), (c) or (d) above may be owned by a person 
who is not an Immediate Family Member or by an entity that is not 
beneficially owned solely by Immediate Family Members.  "Immediate Family 
Members" shall be defined as the spouse and natural or adopted children or 
grandchildren of the Participant and their spouses.  To the extent that an 
Incentive Stock Option is permitted to be transferred during the lifetime of 
the Participant, it shall be treated thereafter as a Nonqualified Stock 
Option.  Any attempted assignment, transfer, pledge, hypothecation or other 
disposition of Awards, or levy of attachment or similar process upon Awards 
not specifically permitted herein, shall be null and void and without effect. 
 The designation of a Designated Beneficiary shall not be a violation of this 
Section 11(c).

         (d)  SHARE CERTIFICATES.  All certificates for Shares or other 
securities delivered under the Plan pursuant to any Award or the exercise 
thereof shall be subject to such stop transfer orders and other restrictions 
as the Committee may deem advisable under the Plan or the rules, regulations, 
and other requirements of the SEC, any stock exchange upon which such Shares 
or other securities are then listed, and any applicable federal or state 
laws, and the Committee may cause a legend or legends to be put on any such 
certificates to make appropriate reference to such restrictions.

         (e)  NO LIMIT ON OTHER COMPENSATION ARRANGEMENTS.  Nothing contained 
in the Plan shall prevent the Company from adopting or continuing in effect 
other compensation arrangements, which may, but need not, provide for the 
grant of options, stock appreciation rights and other types of Awards 
provided for hereunder (subject to stockholder approval of any such 
arrangement if approval is required), and such arrangements may be either 
generally applicable or applicable only in specific cases.

         (f)  NO RIGHT TO EMPLOYMENT.  The grant of an Award shall not be 
construed as giving a Participant the right to be retained in the employ of 
or as a consultant or adviser to the Company or any Subsidiary or in the 
employ of or as a consultant or adviser to any other entity providing 
services to the Company.  The Company or any Subsidiary or any such entity 
may at any time dismiss a Participant from employment, or terminate any 
arrangement pursuant to which the Participant provides services to the 
Company or a Subsidiary, free from any liability or any claim under the Plan, 
unless otherwise expressly provided in the Plan or in any Award Agreement.  
No Eligible Individual or other person shall have any claim to be granted any 
Award, and there is no obligation for uniformity of treatment of Eligible 
Individuals, Participants or holders or beneficiaries of Awards.

                                    -10-
<PAGE>


         (g)  GOVERNING LAW.  The validity, construction, and effect of the 
Plan, any rules and regulations relating to the Plan and any Award Agreement 
shall be determined in accordance with the laws of the State of Delaware.

         (h)  SEVERABILITY.  If any provision of the Plan or any Award is or 
becomes or is deemed to be invalid, illegal, or unenforceable in any 
jurisdiction or as to any Person or Award, or would disqualify the Plan or 
any Award under any law deemed applicable by the Committee, such provision 
shall be construed or deemed amended to conform to applicable laws, or if it 
cannot be construed or deemed amended without, in the determination of the 
Committee, materially altering the intent of the Plan or the Award, such 
provision shall be stricken as to such jurisdiction, Person or Award and the 
remainder of the Plan and any such Award shall remain in full force and 
effect.

         (i)  NO TRUST OR FUND CREATED.  Neither the Plan nor any Award shall 
create or be construed to create a trust or separate fund of any kind or a 
fiduciary relationship between the Company and a Participant or any other 
Person.  To the extent that any Person acquires a right to receive payments 
from the Company pursuant to an Award, such right shall be no greater than 
the right of any unsecured general creditor of the Company.

         (j)  NO FRACTIONAL SHARES.  No fractional Shares shall be issued or 
delivered pursuant to the Plan or any Award, and the Committee shall 
determine whether cash, other securities or other property shall be paid or 
transferred in lieu of any fractional Shares or whether such fractional 
Shares or any rights thereto shall be canceled, terminated, or otherwise 
eliminated.

         (k)  HEADINGS.  Headings are given to the subsections of the Plan 
solely as a convenience to facilitate reference.  Such headings shall not be 
deemed in any way material or relevant to the construction or interpretation 
of the Plan or any provision thereof.


                                 SECTION 12

    TERM OF THE PLAN.  Subject to Section 10(a), the Plan shall remain in 
effect until all Awards permitted to be granted under the Plan have either 
been satisfied, expired or cancelled under the terms of the Plan and any 
restrictions imposed on Shares in connection with their issuance under the 
Plan have lapsed.

         STOCKHOLDER PROTECTION RIGHTS AGREEMENT (as amended from time to time,
this "Agreement"), dated as of ____________, 1997, between Freeport-McMoRan
Sulphur Inc., a Delaware corporation (the "Company"), and MELLON SECURITIES
TRUST COMPANY, a NEW YORK corporation, as Rights Agent (the "Rights Agent",
which term shall include any successor Rights Agent hereunder).

                                 W I T N E S S E T H:

         WHEREAS, the Board of Directors of the Company has (a) authorized and
declared a dividend of one right ("Right") in respect of each share of Common
Stock (as hereinafter defined) held of record as of the close of business on
____________, 1997 (the "Record Time") and (b) authorized the issuance of one
Right in respect of each share of Common Stock issued after the Record Time and
prior to the Separation Time (as hereinafter defined) and, to the extent
provided in Section 5.3, each share of Common Stock issued after the Separation
Time;

         WHEREAS, subject to the terms hereof, each Right entitles the holder
thereof, after the Separation Time, to purchase securities of the Company (or,
in certain cases, of certain other entities) pursuant to the terms and subject
to the conditions set forth herein; and

         WHEREAS, the Company desires to appoint the Rights Agent to act on
behalf of the Company, and the Rights Agent is willing so to act, in connection
with the issuance, transfer, exchange and replacement of Rights Certificates (as
hereinafter defined), the exercise of Rights and other matters referred to
herein;

         NOW THEREFORE, in consideration of the premises and the respective
agreements set forth herein, the parties hereby agree as follows:

                                      -1-

<PAGE>

                                      ARTICLE I

                                 CERTAIN DEFINITIONS

         1.1  CERTAIN DEFINITIONS.  For purposes of this Agreement, the
following terms have the meanings indicated:

         "Acquiring Person" shall mean any Person who is a Beneficial Owner

that the term "Acquiring Person" shall not include (i) any Person who shall 
become the Beneficial Owner of 15% or more of the outstanding shares of 
Common Stock solely as a result of an acquisition by the Company of shares of 
Common Stock, until such time thereafter as such Person shall become the 
Beneficial Owner (other than by means of a stock dividend or stock split) of 
any additional shares of Common Stock, (ii) any Person who shall become the 
Beneficial Owner of 15% or more of the outstanding shares of Common Stock but 
who acquired shares of Common Stock without any plan or intention to seek or 
affect control of the Company, if such Person promptly thereafter enters into 
and delivers to the Company an irrevocable commitment promptly to divest, and 
thereafter promptly divests (without exercising or retaining any power, 
including voting, with respect to such shares), sufficient shares of Common 
Stock (or securities convertible into, exchangeable into or exercisable for 
Common Stock) so that such Person ceases to be the Beneficial Owner of 15% or 
more of the outstanding shares of Common Stock or (iii) any Person who 
Beneficially Owns shares of Common Stock consisting solely of one or more of 
(A) shares of Common Stock Beneficially Owned pursuant to the grant or 
exercise of an option granted to such Person by the Company in connection 
with an agreement to merge with, or acquire, the Company at a time at which 
there is no Acquiring Person, (B) shares of Common Stock (or securities 
convertible into, exchangeable into or exercisable for Common Stock) 
Beneficially Owned by such Person or its Affiliates or Associates at the time 
of grant of such option or (C) shares of Common Stock (or securities

convertible into, exchangeable into or exercisable for Common Stock) acquired

Common Stock.  In addition, the Company, any wholly-owned Subsidiary of the 
Company and any employee benefit plan of the Company or a wholly-owned 
Subsidiary of the Company shall not be an Acquiring Person.

rights, exchange rights, rights (other than the Rights), warrants or options, 
or otherwise; PROVIDED, HOWEVER, that a Person shall not be deemed the

Person's Affiliates or Associates until such tendered security is accepted 
for payment or exchange or (ii) solely because such Person or any of such 
Person's Affiliates or Associates has or shares the power to vote or direct 
the voting of such security pursuant to a revocable proxy given in response 

                                      -3-

Date; PROVIDED, that if the foregoing results in the Separation Time being 
prior to the Record Time, the Separation Time shall be the Record Time and 
PROVIDED FURTHER, that if any tender or exchange offer referred to in clause

                                      THE RIGHTS

         2.1  SUMMARY OF RIGHTS.  As soon as practicable after the Record 
Time, the Company will mail a letter summarizing the terms of the Rights to 
each holder of record of Common Stock as of the Record Time, at such holder's 
address as shown by the records of the Company.

         2.2  LEGEND ON COMMON STOCK CERTIFICATES.  Certificates for the 
Common Stock issued after the Record Time but prior to the Separation Time 
shall evidence one Right for each share of Common Stock represented thereby 
and shall have impressed on, printed on, written on or otherwise affixed to 
them the following legend:

    Until the Separation Time (as defined in the Rights Agreement referred to
    below), this certificate also evidences and entitles the holder hereof to
    certain Rights as set forth in a Rights Agreement, dated as of
    ____________, 1997 (as such may be amended from time to time, the "Rights
    Agreement"), between Freeport-McMoRan Sulphur Inc. (the "Company") and
    MELLON SECURITIES TRUST COMPANY, as Rights Agent, the terms of which are
    hereby incorporated herein by reference and a copy of which is on file at
    the principal executive offices of the Company.  Under certain
    circumstances, as set forth in the Rights Agreement, such Rights may be
    redeemed, may be exchanged for shares of Common Stock or other securities
    or assets of the Company or a Subsidiary of the Company, may expire, may
    become void (if they are "Beneficially Owned" by an "Acquiring Person" or
    an Affiliate or Associate thereof, as such terms are defined in the Rights
    Agreement, or by any transferee of any of the foregoing) or may be
    evidenced by separate certificates and may no longer be evidenced by this
    certificate.  The Company will mail or arrange for the mailing of a copy of
    the Rights Agreement to the holder of this certificate without charge
    within five days after the receipt of a written request therefor.

<PAGE>

Certificates representing shares of Common Stock that are issued and 
outstanding at the Record Time shall evidence one Right for each share of 
Common Stock evidenced thereby notwithstanding the absence of the foregoing 
legend.

         2.3  EXERCISE OF RIGHTS; SEPARATION OF RIGHTS.  (a)  Subject to 
Sections 3.1, 5.1 and 5.10 and subject to adjustment as herein set forth, 
each Right will entitle the holder thereof, after the Separation Time and 
prior to the Expiration Time, to purchase, for the Exercise Price, one 
one-hundredth of a share of Preferred Stock.  

         (b)  Until the Separation Time, (i) no Right may be exercised and 
(ii) each Right will be evidenced by the certificate for the associated share 
of Common Stock (together, in the case of certificates issued prior to the 
Record Time, with the letter mailed to the record holder thereof pursuant to 
Section 2.1) and will be transferable only together with, and will be 
transferred by a transfer (whether with or without such letter) of, such 
associated share.  

         (c)  Subject to the terms hereof, after the Separation Time and 
prior to the Expiration Time, the Rights (i) may be exercised and (ii) may be 
transferred independent of shares of Common Stock.  Promptly following the 
Separation Time, the Rights Agent will mail to each holder of record of 
Common Stock as of the Separation Time (other than any Person whose Rights 
have become void pursuant to Section 3.1(b)), at such holder's address as 
shown by the records of the Company (the Company hereby agreeing to furnish 
copies of such records to the Rights Agent for this purpose), (x) a 
certificate (a "Rights Certificate") in substantially the form of Exhibit A 
hereto appropriately completed, representing the number of Rights held by 
such holder at the Separation Time and having such marks of identification or 
designation and such legends, summaries or endorsements printed thereon as 
the Company may deem appropriate and as are not inconsistent with the 

                                      -10-

<PAGE>

provisions of this Agreement, or as may be required to comply with any law or 
with any rule or regulation made pursuant thereto or with any rule or 
regulation of any national securities exchange or quotation system on which 
the Rights may from time to time be listed or traded, or to conform to usage, 
and (y) a disclosure statement describing the Rights.

         (d)  Subject to the terms hereof, Rights may be exercised on any 
Business Day after the Separation Time and prior to the Expiration Time by 
submitting to the Rights Agent the Rights Certificate evidencing such Rights 
with an Election to Exercise (an "Election to Exercise") substantially in the 
form attached to the Rights Certificate duly completed, accompanied by 
payment in cash, or by certified or official bank check or money order 
payable to the order of the Company, of a sum equal to the Exercise Price 
multiplied by the number of Rights being exercised and a sum sufficient to 
cover any transfer tax or charge which may be payable in respect of any 
transfer involved in the transfer or delivery of Rights Certificates or the 
issuance or delivery of certificates for shares or depositary receipts (or 
both) in a name other than that of the holder of the Rights being exercised.

         (e)  Upon receipt of a Rights Certificate, with an Election to 
Exercise accompanied by payment as set forth in Section 2.3(d), and subject 
to the terms hereof, the Rights Agent will thereupon promptly (i)(A) 
requisition from the Company's transfer agent stock certificates evidencing 
such number of shares or other securities to be purchased (the Company hereby 
irrevocably authorizing its transfer agent to comply with all such 
requisitions) and (B) if the Company elects pursuant to Section 5.5 not to 
issue certificates representing fractional shares, requisition from the 
depositary selected by the Company depositary receipts representing the 
fractional shares to be purchased or requisition from the Company the amount 
of cash to be paid in lieu of fractional shares in accordance with Section 
5.5 and (ii) after receipt of such certificates, depositary receipts and/or 

                                      -11-

<PAGE>

cash, deliver the same to or upon the order of the registered holder of such 
Rights Certificate, registered (in the case of certificates or depositary 
receipts) in such name or names as may be designated by such holder.

         (f)  In case the holder of any Rights shall exercise less than all 
the Rights evidenced by such holder's Rights Certificate, a new Rights 
Certificate evidencing the Rights remaining unexercised will be issued by the 
Rights Agent to such holder or to such holder's duly authorized assigns.

         (g)  The Company covenants and agrees that it will (i) take all such 
action as may be necessary to ensure that all shares delivered upon exercise 
of Rights shall, at the time of delivery of the certificates for such shares 
(subject to payment of the Exercise Price), be duly and validly authorized, 
executed, issued and delivered and fully paid and nonassessable; (ii) take 
all such action as may be necessary to comply with any applicable 
requirements of the Securities Act of 1933 or the Securities Exchange Act of 
1934, and the rules and regulations thereunder, and any other applicable law, 
rule or regulation, in connection with the issuance of any shares upon 
exercise of Rights; and (iii) pay when due and payable any and all federal 
and state transfer taxes and charges which may be payable in respect of the 
original issuance or delivery of the Rights Certificates or of any shares 
issued upon the exercise of Rights, provided that the Company shall not be 
required to pay any transfer tax or charge which may be payable in respect of 
any transfer involved in the transfer or delivery of Rights Certificates or 
the issuance or delivery of certificates for shares in a name other than that 
of the holder of the Rights being transferred or exercised.

         2.4  ADJUSTMENTS TO EXERCISE PRICE; NUMBER OF RIGHTS.  (a)  In the 
event the Company shall at any time after the Record Time and prior to the 
Separation Time (i) declare or pay a dividend on Common Stock payable in 

                                      -12-

<PAGE>

Common Stock, (ii) subdivide the outstanding Common Stock or (iii) combine 
the outstanding Common Stock into a smaller number of shares of Common Stock, 
(x) the Exercise Price in effect after such adjustment will be equal to the 
Exercise Price in effect immediately prior to such adjustment divided by the 
number of shares of Common Stock (the "Expansion Factor") that a holder of 
one share of Common Stock immediately prior to such dividend, subdivision or 
combination would hold thereafter as a result thereof and (y) each Right held 
prior to such adjustment will become that number of Rights equal to the 
Expansion Factor, and the adjusted number of Rights will be deemed to be 
distributed among the shares of Common Stock with respect to which the 
original Rights were associated (if they remain outstanding) and the shares 
issued in respect of such dividend, subdivision or combination, so that each 
such share of Common Stock will have exactly one Right associated with it.  
Each adjustment made pursuant to this paragraph shall be made as of the 
payment or effective date for the applicable dividend, subdivision or 
combination.

         In the event the Company shall at any time after the Record Time and 
prior to the Separation Time issue any shares of Common Stock otherwise than 
in a transaction referred to in the preceding paragraph, each such share of 
Common Stock so issued shall automatically have one new Right associated with 
it, which Right shall be evidenced by the certificate representing such 
share.  To the extent provided in Section 5.3, Rights shall be issued by the 
Company in respect of shares of Common Stock that are issued or sold by the 
Company after the Separation Time.

         (b)  In the event the Company shall at any time after the Record 
Time and prior to the Separation Time issue or distribute any securities or 
assets in respect of, in lieu of or in exchange for Common Stock (other than 

                                      -13-

<PAGE>

pursuant to a regular periodic cash dividend or a dividend paid solely in 
Common Stock) whether by dividend, in a reclassification or recapitalization 
(including any such transaction involving a merger, consolidation or share 
exchange), or otherwise, the Company shall make such adjustments, if any, in 
the Exercise Price, number of Rights and/or securities or other property 
purchasable upon exercise of Rights as the Board of Directors of the Company, 
in its sole discretion, may deem to be appropriate under the circumstances in 
order to adequately protect the interests of the holders of Rights generally, 
and the Company and the Rights Agent shall amend this Agreement as necessary 
to provide for such adjustments.

         (c)  Each adjustment to the Exercise Price made pursuant to this 
Section 2.4 shall be calculated to the nearest cent.  Whenever an adjustment 
to the Exercise Price is made pursuant to this Section 2.4, the Company shall 
(i) promptly prepare a certificate setting forth such adjustment and a brief 
statement of the facts accounting for such adjustment, (ii) promptly file 
with the Rights Agent and with each transfer agent for the Common Stock a 
copy of such certificate and (iii) mail a brief summary thereof to each 
holder of Rights.

         (d)  Irrespective of any adjustment or change in the securities 
purchasable upon exercise of the Rights, the Rights Certificates theretofore 
and thereafter issued may continue to express the securities so purchasable 
which were expressed in the initial Rights Certificates issued hereunder.

         2.5  DATE ON WHICH EXERCISE IS EFFECTIVE.  Each person in whose name 
any certificate for shares is issued upon the exercise of Rights shall for 
all purposes be deemed to have become the holder of record of the shares 
represented thereby on, and such certificate shall be dated, the date upon 
which the Rights Certificate evidencing such Rights was duly surrendered and 
payment of the Exercise Price for such Rights (and any applicable taxes and 
other governmental charges payable by the exercising holder hereunder) was 

                                      -14-

<PAGE>

made; PROVIDED, HOWEVER, that if the date of such surrender and payment is a 
date upon which the stock transfer books of the Company are closed, such 
person shall be deemed to have become the record holder of such shares on, 
and such certificate shall be dated, the next succeeding Business Day on 
which the stock transfer books of the Company are open.  

         2.6  EXECUTION, AUTHENTICATION, DELIVERY AND DATING OF RIGHTS 
CERTIFICATES.  (a)  The Rights Certificates shall be executed on behalf of 
the Company by its Chairman of the Board, President or its Treasurer, under 
its corporate seal reproduced thereon attested by its Secretary or one of its 
Assistant Secretaries.  The signature of any of these officers on the Rights 
Certificates may be manual or facsimile.

         Rights Certificates bearing the manual or facsimile signatures of 
individuals who were at any time the proper officers of the Company shall 
bind the Company, notwithstanding that such individuals or any of them have 
ceased to hold such offices prior to the countersignature and delivery of 
such Rights Certificates.

         Promptly after the Company learns of the Separation Time, the 
Company will notify the Rights Agent of such Separation Time and will deliver 
Rights Certificates executed by the Company to the Rights Agent for 
countersignature, and, subject to Section 3.1(b), the Rights Agent shall 
manually countersign and deliver such Rights Certificates to the holders of 
the Rights pursuant to Section 2.3(c) hereof.  No Rights Certificate shall be 
valid for any purpose unless manually countersigned by the Rights Agent.

         (b)  Each Rights Certificate shall be dated the date of 
countersignature thereof.

         2.7  REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.  (a)  
After the Separation Time, the Company will cause to be kept a register (the 
"Rights Register") in which, subject to such reasonable regulations as it may 

                                      -15-

<PAGE>

prescribe, the Company will provide for the registration and transfer of 
Rights.  The Rights Agent is hereby appointed "Rights Registrar" for the 
purpose of maintaining the Rights Register for the Company and registering 
Rights and transfers of Rights after the Separation Time as herein provided.  
In the event that the Rights Agent shall cease to be the Rights Registrar, 
the Rights Agent will have the right to examine the Rights Register at all 
reasonable times after the Separation Time.

         After the Separation Time and prior to the Expiration Time, upon 
surrender for registration of transfer or exchange of any Rights Certificate, 
and subject to the provisions of Section 2.7(c) and (d), the Company will 
execute, and the Rights Agent will countersign and deliver, in the name of 
the holder or the designated transferee or transferees, as required pursuant 
to the holder's instructions, one or more new Rights Certificates evidencing 
the same aggregate number of Rights as did the Rights Certificate so 
surrendered.

         (b)  Except as otherwise provided in Section 3.1(b), all Rights 
issued upon any registration of transfer or exchange of Rights Certificates 
shall be the valid obligations of the Company, and such Rights shall be 
entitled to the same benefits under this Agreement as the Rights surrendered 
upon such registration of transfer or exchange.

         (c)  Every Rights Certificate surrendered for registration of 
transfer or exchange shall be duly endorsed, or be accompanied by a written 
instrument of transfer in form satisfactory to the Company or the Rights 
Agent, as the case may be, duly executed by the holder thereof or such 
holder's attorney duly authorized in writing.  As a condition to the issuance 
of any new Rights Certificate under this Section 2.7, the Company may require 
the payment of a sum sufficient to cover any tax or other governmental charge 
that may be imposed in relation thereto.

                                      -16-

<PAGE>

         (d)  The Company shall not be required to register the transfer or
exchange of any Rights after such Rights have become void under Section 3.1(b),
been exchanged under Section 3.1(c) or been redeemed or terminated under
Section 5.1.

         2.8  MUTILATED, DESTROYED, LOST AND STOLEN RIGHTS CERTIFICATES.  (a) 
If any mutilated Rights Certificate is surrendered to the Rights Agent prior 
to the Expiration Time, then, subject to Sections 3.1(b) and 5.1, the Company 
shall execute and the Rights Agent shall countersign and deliver in exchange 
therefor a new Rights Certificate evidencing the same number of Rights as did 
the Rights Certificate so surrendered.

         (b)  If there shall be delivered to the Company and the Rights Agent 
prior to the Expiration Time (i) evidence to their satisfaction of the 
destruction, loss or theft of any Rights Certificate and (ii) such security 
or indemnity as may be required by them to save each of them and any of their 
agents harmless, then, subject to Sections 3.1(b) and 5.1 and in the absence 
of notice to the Company or the Rights Agent that such Rights Certificate has 
been acquired by a BONA FIDE purchaser, the Company shall execute and upon 
its request the Rights Agent shall countersign and deliver, in lieu of any 
such destroyed, lost or stolen Rights Certificate, a new Rights Certificate 
evidencing the same number of Rights as did the Rights Certificate so 
destroyed, lost or stolen.

         (c)  As a condition to the issuance of any new Rights Certificate 
under this Section 2.8, the Company may require the payment of a sum 
sufficient to cover any tax or other governmental charge that may be imposed 
in relation thereto and any other expenses (including the fees and expenses 
of the Rights Agent) connected therewith.

         (d)  Every new Rights Certificate issued pursuant to this Section 
2.8 in lieu of any destroyed, lost or stolen Rights Certificate shall 

                                      -17-

<PAGE>

evidence an original additional contractual obligation of the Company, 
whether or not the destroyed, lost or stolen Rights Certificate shall be at 
any time enforceable by anyone, and shall be entitled to all the benefits of 
this Agreement equally and proportionately with any and all other Rights duly 
issued hereunder.

         2.9  PERSONS DEEMED OWNERS.  Prior to due presentment of a Rights 
Certificate (or, prior to the Separation Time, the associated Common Stock 
certificate) for registration of transfer, the Company, the Rights Agent and 
any agent of the Company or the Rights Agent may deem and treat the person in 
whose name such Rights Certificate (or, prior to the Separation Time, such 
Common Stock certificate) is registered as the absolute owner thereof and of 
the Rights evidenced thereby for all purposes whatsoever, including the 
payment of the Redemption Price and neither the Company nor the Rights Agent 
shall be affected by any notice to the contrary.  As used in this Agreement, 
unless the context otherwise requires, the term "holder" of any Rights shall 
mean the registered holder of such Rights (or, prior to the Separation Time, 
the associated shares of Common Stock).

         2.10  DELIVERY AND CANCELLATION OF CERTIFICATES.  All Rights 
Certificates surrendered upon exercise or for registration of transfer or 
exchange shall, if surrendered to any person other than the Rights Agent, be 
delivered to the Rights Agent and, in any case, shall be promptly cancelled 
by the Rights Agent.  The Company may at any time deliver to the Rights Agent 
for cancellation any Rights Certificates previously countersigned and 
delivered hereunder which the Company may have acquired in any manner 
whatsoever, and all Rights Certificates so delivered shall be promptly 
cancelled by the Rights Agent.  No Rights Certificates shall be countersigned 
in lieu of or in exchange for any Rights Certificates cancelled as provided 
in this Section 2.10, except as expressly permitted by this Agreement.  The 
Rights Agent shall destroy all cancelled Rights Certificates and deliver a 
certificate of destruction to the Company.

exercise thereof in accordance with the terms hereof (but subject to Section 
5.10), that number of shares of Common Stock having an aggregate Market Price 
on the Stock Acquisition Date equal to twice the Exercise Price for an amount 
in cash equal to the Exercise Price (such right to be appropriately adjusted 
in order to protect the interests of the holders of Rights generally in the 
event that on or after such Stock Acquisition Date an event of a type 
analogous to any of the events described in Section 2.4(a) or (b) shall have 
occurred with respect to the Common Stock).

         (b)  Notwithstanding the foregoing,  any Rights that are or were 
Beneficially Owned on or after the Stock Acquisition Date by an Acquiring 
Person or an Affiliate or Associate thereof or by any transferee, direct or 
indirect, of any of the foregoing shall become void and any holder of such 
Rights (including transferees) shall thereafter have no right to exercise or 
transfer such Rights under any provision of this Agreement.  If any Rights 
Certificate is presented for assignment or exercise and the Person presenting 
the same will not complete the certification set forth at the end of the form 
of assignment or notice of election to exercise and provide such additional 
evidence of the identity of the Beneficial Owner and its Affiliates and 
Associates (or former Beneficial Owners and their Affiliates and Associates) 
as the Company shall reasonably request, then the Company shall be entitled 
conclusively to deem the Beneficial Owner thereof to be an Acquiring Person 
or an Affiliate or Associate thereof or a transferee of any of the foregoing 
and accordingly will deem the Rights evidenced thereby to be void and not 
transferable or exercisable.

         (c)  The Board of Directors of the Company may, at its option, at 
any time after a Flip-in Date and prior to the time that an Acquiring Person 

                                      -20-

<PAGE>

becomes the Beneficial Owner of more than 50% of the outstanding shares of 
Common Stock, elect to exchange all (but not less than all) the then 
outstanding Rights (which shall not include Rights that have become void 
pursuant to the provisions of Section 3.1(b)) for shares of Common Stock at 
an exchange ratio of one share of Common Stock per Right, appropriately 
adjusted in order to protect the interests of holders of Rights generally in 
the event that after the Separation Time an event of a type analogous to any 
of the events described in Section 2.4(a) or (b) shall have occurred with 
respect to the Common Stock (such exchange ratio, as adjusted from time to 
time, being hereinafter referred to as the "Exchange Ratio").

         Immediately upon the action of the Board of Directors of the Company 
electing to exchange the Rights, without any further action and without any 
notice, the right to exercise the Rights will terminate and each Right (other 
than Rights that have become void pursuant to Section 3.1(b)) will thereafter 
represent only the right to receive a number of shares of Common Stock equal 
to the Exchange Ratio.  Promptly after the action of the Board of Directors 
electing to exchange the Rights, the Company shall give notice thereof 
(specifying the steps to be taken to receive shares of Common Stock in 
exchange for Rights) to the Rights Agent and the holders of the Rights (other 
than Rights that have become void pursuant to Section 3.1(b)) outstanding 
immediately prior thereto by mailing such notice in accordance with Section 
5.9.

         Each Person in whose name any certificate for shares is issued upon 
the exchange of Rights pursuant to this Section 3.1(c) or Section 3.1(d) 
shall for all purposes be deemed to have become the holder of record of the 
shares represented thereby on, and such certificate shall be dated, the date 
upon which the Rights Certificate evidencing such Rights was duly surrendered 
and payment of any applicable taxes and other governmental charges payable by 
the holder was made; PROVIDED, HOWEVER, that if the date of such surrender 

                                      -21-

<PAGE>

and payment is a date upon which the stock transfer books of the Company are 
closed, such Person shall be deemed to have become the record holder of such 
shares on, and such certificate shall be dated, the next succeeding Business 
Day on which the stock transfer books of the Company are open.

         (d)  Whenever the Company shall become obligated under Section 
3.1(a) or (c) to issue shares of Common Stock upon exercise of or in exchange 
for Rights, the Company, at its option, may substitute therefor shares of 
Preferred Stock, at a ratio of one one-hundredth of a share of Preferred 
Stock for each share of Common Stock so issuable.

         (e)  In the event that there shall not be sufficient treasury shares 
or authorized but unissued shares of Common Stock or Preferred Stock of the 
Company to permit the exercise or exchange in full of the Rights in 
accordance with Section 3.1(a) or (c), the Company shall either (i) call a 
meeting of stockholders seeking approval to cause sufficient additional 
shares to be authorized (provided that if such approval is not obtained the 
Company will take the action specified in clause (ii) of this sentence) or 
(ii) take such action as shall be necessary to ensure and provide, to the 
extent permitted by applicable law and any agreements or instruments in 
effect on the Stock Acquisition Date to which it is a party, that each Right 
shall thereafter constitute the right to receive, (x) at the Company's 
option, either (A) in return for the Exercise Price, debt or equity 
securities or other assets (or a combination thereof) having a fair value 
equal to twice the Exercise Price, or (B) without payment of consideration 
(except as otherwise required by applicable law), debt or equity securities 
or other assets (or a combination thereof) having a fair value equal to the 
Exercise Price, or (y) if the Board of Directors of the Company elects to 
exchange the Rights in accordance with Section 3.1(c), debt or equity 
securities or other assets (or a combination thereof) having a fair value 
equal to the product of the Market Price of a share of Common Stock on the 
Flip-in Date times the Exchange Ratio in effect on the Flip-in Date, where in 

                                      -22-

<PAGE>

any case set forth in (x) or (y) above the fair value of such debt or equity 
securities or other assets shall be as determined in good faith by the Board 
of Directors of the Company, after consultation with a nationally recognized 
investment banking firm.  

         3.2  FLIP-OVER.  (a)  Prior to the Expiration Time, the Company 
shall not enter into any agreement with an Acquiring Person (or any of its 
Affiliates or Associates) with respect to, consummate or permit to occur any 
Flip-over Transaction or Event unless and until it shall have entered into a 
supplemental agreement with the Flip-over Entity, for the benefit of the 
holders of the Rights, providing that, upon consummation or occurrence of the 
Flip-over Transaction or Event (i) each Right shall thereafter constitute the 
right to purchase from the Flip-over Entity, upon exercise thereof in 
accordance with the terms hereof, that number of shares of Flip-over Stock of 
the Flip-over Entity having an aggregate Market Price on the date of 
consummation or occurrence of such Flip-over Transaction or Event equal to 
twice the Exercise Price for an amount in cash equal to the Exercise Price 
(such right to be appropriately adjusted in order to protect the interests of 
the holders of Rights generally in the event that after such date of 
consummation or occurrence an event of a type analogous to any of the events 
described in Section 2.4(a) or (b) shall have occurred with respect to the 
Flip-over Stock) and (ii) the Flip-over Entity shall thereafter be liable 
for, and shall assume, by virtue of such Flip-over Transaction or Event and 
such supplemental agreement, all the obligations and duties of the Company 
pursuant to this Agreement.  The provisions of this Section 3.2 shall apply 
to successive Flip-over Transactions or Events.

         (b)  Prior to the Expiration Time, unless the Rights will be 
redeemed pursuant to  Section 5.1 hereof in connection therewith, the Company 
shall not enter into any agreement with respect to, consummate or permit to 

                                      -23-

<PAGE>

occur any Flip-over Transaction or Event if at the time thereof there are any 
rights, warrants or securities outstanding or any other arrangements, 
agreements or instruments that would eliminate or otherwise diminish in any 
material respect the benefits intended to be afforded by this Rights 
Agreement to the holders of Rights upon consummation of such transaction.

                                THE RIGHTS AGENT

         4.1  GENERAL.  (a)  The Company hereby appoints the Rights Agent to 
act as agent for the Company in accordance with the terms and conditions 
hereof, and the Rights Agent hereby accepts such appointment.  The Company 
agrees to pay to the Rights Agent reasonable compensation for all services 
rendered by it hereunder and, from time to time, on demand of the Rights 
Agent, its reasonable expenses and counsel fees and other disbursements 
incurred in the administration and execution of this Agreement and the 
exercise and performance of its duties hereunder.  The Company also agrees to 
indemnify the Rights Agent for, and to hold it harmless against, any loss, 
liability, or expense, incurred without negligence, bad faith or willful 
misconduct on the part of the Rights Agent, for anything done or omitted to 
be done by the Rights Agent in connection with the acceptance and 
administration of this Agreement, including the costs and expenses of 
defending against any claim of liability.

         (b)  The Rights Agent shall be protected and shall incur no 
liability for or in respect of any action taken, suffered or omitted by it in 
connection with its administration of this Agreement in reliance upon any 
certificate for securities purchasable upon exercise of Rights, Rights 
Certificate, certificate for other securities of the Company, instrument of

<PAGE>

assignment or transfer, power of attorney, endorsement, affidavit, letter, 
notice, direction, consent, certificate, statement, or other paper or 
document believed by it to be genuine and to be signed, executed and, where 
necessary, verified or acknowledged, by the proper person or persons.

         4.2  MERGER OR CONSOLIDATION OR CHANGE OF NAME OF RIGHTS AGENT.  (a) 
Any corporation into which the Rights Agent or any successor Rights Agent may 
be merged or with which it may be consolidated, or any corporation resulting 
from any merger or consolidation to which the Rights Agent or any successor 
Rights Agent is a party, or any corporation succeeding to the stockholder 
services business of the Rights Agent or any successor Rights Agent, will be 
the successor to the Rights Agent under this Agreement without the execution 
or filing of any paper or any further act on the part of any of the parties 
hereto, provided that such corporation would be eligible for appointment as a 
successor Rights Agent under the provisions of Section 4.4 hereof.  In case 
at the time such successor Rights Agent succeeds to the agency created by 
this Agreement any of the Rights Certificates have been countersigned but not 
delivered, any such successor Rights Agent may adopt the countersignature of 
the predecessor Rights Agent and deliver such Rights Certificates so 
countersigned; and in case at that time any of the Rights Certificates have 
not been countersigned, any successor Rights Agent may countersign such 
Rights Certificates either in the name of the predecessor Rights Agent or in 
the name of the successor Rights Agent; and in all such cases such Rights 
Certificates will have the full force provided in the Rights Certificates and 
in this Agreement.

         (b)  In case at any time the name of the Rights Agent is changed and 
at such time any of the Rights Certificates shall have been countersigned but 
not delivered, the Rights Agent may adopt the countersignature under its 
prior name and deliver Rights Certificates so countersigned; and in case at 
that time any of the Rights Certificates shall not have been countersigned, 
the Rights Agent may countersign such Rights Certificates either in its prior 

                                      -25-

<PAGE>

name or in its changed name; and in all such cases such Rights Certificates 
shall have the full force provided in the Rights Certificates and in this 
Agreement.

         4.3  DUTIES OF RIGHTS AGENT.  The Rights Agent undertakes the duties 
and obligations imposed by this Agreement upon the following terms and 
conditions, by all of which the Company and the holders of Rights 
Certificates, by their acceptance thereof, shall be bound:

         (a)  The Rights Agent may consult with legal counsel (who may be 
legal counsel for the Company), and the opinion of such counsel will be full 
and complete authorization and protection to the Rights Agent as to any 
action taken or omitted by it in good faith and in accordance with such 
opinion.

         (b)  Whenever in the performance of its duties under this Agreement 
the Rights Agent deems it necessary or desirable that any fact or matter be 
proved or established by the Company prior to taking or suffering any action 
hereunder, such fact or matter (unless other evidence in respect thereof be 
herein specifically prescribed) may be deemed to be conclusively proved and 
established by a certificate signed by a person believed by the Rights Agent 
to be the Chairman of the Board, the President or any Vice President and by 
the Treasurer or any Assistant Treasurer or the Secretary or any Assistant 
Secretary of the Company and delivered to the Rights Agent; and such 
certificate will be full authorization to the Rights Agent for any action 
taken or suffered in good faith by it under the provisions of this Agreement 
in reliance upon such certificate.

         (c)  The Rights Agent will be liable hereunder only for its own 
negligence, bad faith or willful misconduct.

         (d)  The Rights Agent will not be liable for or by reason of any of 
the statements of fact or recitals contained in this Agreement or in the 
certificates for securities purchasable upon exercise of Rights or the Rights 

                                      -26-

<PAGE>

Certificates (except its countersignature thereof) or be required to verify 
the same, but all such statements and recitals are and will be deemed to have 
been made by the Company only.

         (e)  The Rights Agent will not be under any responsibility in 
respect of the validity of this Agreement or the execution and delivery 
hereof (except the due authorization, execution and delivery hereof by the 
Rights Agent) or in respect of the validity or execution of any certificate 
for securities purchasable upon exercise of Rights or Rights Certificate 
(except its countersignature thereof); nor will it be responsible for any 
breach by the Company of any covenant or condition contained in this 
Agreement or in any Rights Certificate; nor will it be responsible for any 
change in the exercisability of the Rights (including the Rights becoming 
void pursuant to Section 3.1(b) hereof) or any adjustment required under the 
provisions of Section 2.4, 3.1 or 3.2 hereof or responsible for the manner, 
method or amount of any such adjustment or the ascertaining of the existence 
of facts that would require any such adjustment (except with respect to the 
exercise of Rights after receipt of the certificate contemplated by Section 
2.4 describing any such adjustment); nor will it by any act hereunder be 
deemed to make any representation or warranty as to the authorization or 
reservation of any securities purchasable upon exercise of Rights or any 
Rights or as to whether any securities purchasable upon exercise of Rights 
will, when issued, be duly and validly authorized, executed, issued and 
delivered and fully paid and nonassessable.

         (f)  The Company agrees that it will perform, execute, acknowledge 
and deliver or cause to be performed, executed, acknowledged and delivered 
all such further and other acts, instruments and assurances as may reasonably 
be required by the Rights Agent for the carrying out or performing by the 
Rights Agent of the provisions of this Agreement.

                                      -27-

<PAGE>

         (g)  The Rights Agent is hereby authorized and directed to accept 
instructions with respect to the performance of its duties hereunder from any 
person believed by the Rights Agent to be the Chairman of the Board, the 
President, the Secretary or any Assistant Secretary or the Treasurer of the 
Company, and to apply to such persons for advice or instructions in 
connection with its duties, and it shall not be liable for any action taken 
or suffered by it in good faith in accordance with instructions of any such 
person.

         (h)  The Rights Agent and any stockholder, director, officer or 
employee of the Rights Agent may buy, sell or deal in Common Stock, Rights or 
other securities of the Company or become pecuniarily interested in any 
transaction in which the Company may be interested, or contract with or lend 
money to the Company or otherwise act as fully and freely as though it were 
not Rights Agent under this Agreement.  Nothing herein shall preclude the 
Rights Agent from acting in any other capacity for the Company or for any 
other legal entity.

         (i)  The Rights Agent may execute and exercise any of the rights or 
powers hereby vested in it or perform any duty hereunder either itself or by 
or through its attorneys or agents, and the Rights Agent will not be 
answerable or accountable for any act, default, neglect or misconduct of any 
such attorneys or agents or for any loss to the Company resulting from any 
such act, default, neglect or misconduct, provided reasonable care was 
exercised in the selection and continued employment thereof.

         4.4  CHANGE OF RIGHTS AGENT.  The Rights Agent may resign and be 
discharged from its duties under this Agreement upon 90 days' notice (or such 
lesser notice as is acceptable to the Company) in writing mailed to the 
Company and to each transfer agent of Common Stock by registered or certified 

                                      -28-

<PAGE>

mail, and to the holders of the Rights in accordance with Section 5.9.  The 
Company may remove the Rights Agent upon 30 days' notice in writing, mailed 
to the Rights Agent and to each transfer agent of the Common Stock by 
registered or certified mail, and to the holders of the Rights in accordance 
with Section 5.9.  If the Rights Agent should resign or be removed or 
otherwise become incapable of acting, the Company will appoint a successor to 
the Rights Agent.  If the Company fails to make such appointment within a 
period of 30 days after such removal or after it has been notified in writing 
of such resignation or incapacity by the resigning or incapacitated Rights 
Agent or by the holder of any Rights (which holder shall, with such notice, 
submit such holder's Rights Certificate for inspection by the Company), then 
the holder of any Rights may apply to any court of competent jurisdiction for 
the appointment of a new Rights Agent.  Any successor Rights Agent, whether 
appointed by the Company or by such a court, shall be a corporation organized 
and doing business under the laws of the United States or of the State of New 
York, in good standing, having its principal office in the State of New York, 
which is authorized under such laws to exercise the powers of the Rights 
Agent contemplated by this Agreement and is subject to supervision or 
examination by federal or state authority and which has at the time of its 
appointment as Rights Agent a combined capital and surplus of at least 
$50,000,000.  After appointment, the successor Rights Agent will be vested 
with the same powers, rights, duties and responsibilities as if it had been 
originally named as Rights Agent without further act or deed; but the 
predecessor Rights Agent shall deliver and transfer to the successor Rights 
Agent any property at the time held by it hereunder, and execute and deliver 
any further assurance, conveyance, act or deed necessary for the purpose.  
Not later than the effective date of any such appointment, the Company will 
file notice thereof in writing with the predecessor Rights Agent and each 
transfer agent of the Common Stock, and mail a notice thereof in writing to 
the holders of the Rights.  Failure to give any notice provided for in this 
Section 4.4, however, or any defect therein, shall not affect the legality or 
validity of the resignation or removal of the Rights Agent or the appointment 
of the successor Rights Agent, as the case may be.

                              ARTICLE V 
                            MISCELLANEOUS

         5.1  REDEMPTION.  (a)  The Board of Directors of the Company may, at 
its option, at any time prior to the close of business on the Flip-in Date, 
elect to redeem all (but not less than all) the then outstanding Rights at 
the Redemption Price and the Company, at its option, may pay the Redemption 
Price either in cash or shares of Common Stock or other securities of the 
Company deemed by the Board of Directors, in the exercise of its sole 
discretion, to be at least equivalent in value to the Redemption Price.

         (b)  Immediately upon the action of the Board of Directors of the 
Company electing to redeem the Rights (or, if the resolution of the Board of 
Directors electing to redeem the Rights states that the redemption will not 
be effective until the occurrence of a specified future time or event, upon 
the occurrence of such future time or event), without any further action and 
without any notice, the right to exercise the Rights will terminate and each 
Right will thereafter represent only the right to receive the Redemption 
Price in cash or securities, as determined by the Board of Directors.  
Promptly after the Rights are redeemed, the Company shall give notice of such 
redemption to the Rights Agent and the holders of the then outstanding Rights 
by mailing such notice in accordance with Section 5.9.

         5.2  EXPIRATION.  The Rights and this Agreement shall expire at the 
Expiration Time and no Person shall have any rights pursuant to this 
Agreement or any Right after the Expiration Time, except, if the Rights are 
exchanged or redeemed, as provided in Section 3.1(c), 3.1(d), 3.1(e), 3.2 or 
5.1 hereof.

                                      -30-

<PAGE>

         5.3  ISSUANCE OF NEW RIGHTS CERTIFICATES.  Notwithstanding any of 
the provisions of this Agreement or of the Rights to the contrary, the 
Company may, at its option, issue new Rights Certificates evidencing Rights 
in such form as may be approved by its Board of Directors to reflect any 
adjustment or change in the number or kind or class of shares of stock 
purchasable upon exercise of Rights made in accordance with the provisions of 
this Agreement.  In addition, in connection with the issuance or sale of 
shares of Common Stock by the Company following the Separation Time and prior 
to the Redemption Time or Expiration Time pursuant to the terms of securities 
convertible or redeemable into shares of Common Stock or to options, in each 
case issued or granted prior to, and outstanding at, the Separation Time, the 
Company shall issue to the holders of such shares of Common Stock, Rights 
Certificates representing the appropriate number of Rights in connection with 
the issuance or sale of such shares of Common Stock; PROVIDED, HOWEVER, in 
each case, (i) no such Rights Certificate shall be issued, if, and to the 
extent that, the Company shall be advised by counsel that such issuance would 
create a significant risk of material adverse tax consequences to the Company 
or to the Person to whom such Rights Certificates would be issued, (ii) no 
such Rights Certificates shall be issued if, and to the extent that, 
appropriate adjustment shall have otherwise been made in lieu of the issuance 
thereof, and (iii) the Company shall have no obligation to distribute Rights 
Certificates to any Acquiring Person or Affiliate or Associate of an 
Acquiring Person or any transferee of any of the foregoing.

         5.4  SUPPLEMENTS AND AMENDMENTS.  The Company and the Rights Agent 
may from time to time supplement or amend this Agreement without the approval 
of any holders of Rights (i) prior to the close of business on the Flip-in 
Date, in any respect and (ii) after the close of business on the Flip-in 
Date, to make any changes that the Company may deem necessary or desirable 
and which shall not materially adversely affect the interests of the holders 

                                      -31-

<PAGE>

of Rights generally or in order to cure any ambiguity or to correct or 
supplement any provision contained herein which may be inconsistent with any 
other provisions herein or otherwise defective.  The Rights Agent will duly 
execute and deliver any supplement or amendment hereto requested by the 
Company which satisfies the terms of the preceding sentence.

         5.5  FRACTIONAL SHARES.  If the Company elects not to issue 
certificates representing fractional shares upon exercise or redemption of 
Rights, the Company shall, in lieu thereof, in the sole discretion of the 
Board of Directors, either (a) evidence such fractional shares by depositary 
receipts issued pursuant to an appropriate agreement between the Company and 
a depositary selected by it, providing that each holder of a depositary 
receipt shall have all of the rights, privileges and preferences to which 
such holder would be entitled as a beneficial owner of such fractional share, 
or (b) sell such shares on behalf of the holders of Right and pay to the 
registered holder of such Rights the appropriate fraction of price per share 
received upon such sale.

         5.6  RIGHTS OF ACTION.  Subject to the terms of this Agreement 
(including Section 3.1(b)), rights of action in respect of this Agreement, 
other than rights of action vested solely in the Rights Agent, are vested in 
the respective holders of the Rights; and any holder of any Rights, without 
the consent of the Rights Agent or of the holder of any other Rights, may, on 
such holder's own behalf and for such holder's own benefit and the benefit of 
other holders of Rights, enforce, and may institute and maintain any suit, 
action or proceeding against the Company to enforce, or otherwise act in 
respect of, such holder's right to exercise such holder's Rights in the 
manner provided in such holder's Rights Certificate and in this Agreement.  
Without limiting the foregoing or any remedies available to the holders of 
Rights, it is specifically acknowledged that the holders of Rights would not 

                                      -32-

<PAGE>

have an adequate remedy at law for any breach of this Agreement and will be 
entitled to specific performance of the obligations under, and injunctive 
relief against actual or threatened violations of, the obligations of any 
Person subject to this Agreement.

         5.7  HOLDER OF RIGHTS NOT DEEMED A STOCKHOLDER.  No holder, as such, 
of any Rights shall be entitled to vote, receive dividends or be deemed for 
any purpose the holder of shares or any other securities which may at any 
time be issuable on the exercise of such Rights, nor shall anything contained 
herein or in any Rights Certificate be construed to confer upon the holder of 
any Rights, as such, any of the rights of a stockholder of the Company or any 
right to vote for the election of directors or upon any matter submitted to 
stockholders at any meeting thereof, or to give or withhold consent to any 
corporate action, or to receive notice of meetings or other actions affecting 
stockholders (except as provided in Section 5.8 hereof), or to receive 
dividends or subscription rights, or otherwise, until such Rights shall have 
been exercised or exchanged in accordance with the provisions hereof.

         5.8  NOTICE OF PROPOSED ACTIONS.  In case the Company shall propose 
after the Separation Time and prior to the Expiration Time (i) to effect or 
permit (in cases where the Company's permission is required) occurrence of 
any Flip-in Date or Flip-over Transaction or Event or (ii) to effect the 
liquidation, dissolution or winding up of the Company, then, in each such 
case, the Company shall give to each holder of a Right, in accordance with 
Section 5.9 hereof, a notice of such proposed action, which shall specify the 
Flip-in Date or the date on which such Flip-over Transaction or Event, 
liquidation, dissolution, or winding up is to take place, and such notice 
shall be so given at least 20 Business Days prior to the date of the taking 
of such proposed action.

Ladies and Gentlemen:

This letter is provided by Valuation Research Corporation ("Valuation") 
reporting the performance of certain limited procedures at the request of the 
Board of Directors of IMC Global Inc., a Delaware Corporation ("IGL"), 
Freeport-McMoRan Inc., a Delaware Corporation ("FTX"), FMRP, Inc., a Delaware 
Corporation ("FMRP"), and Freeport-McMoRan Sulphur Inc., a Delaware 
Corporation ("NEWCO") and a newly formed, wholly-owned subsidiary of 
Freeport-McMoRan Resource Partners, Limited Partnership, a Delaware limited 
partnership ("FRP") to assist in complying with certain conditions to the 
transactions described in the Agreement and Plan of Merger between FTX and 
IGL (the "Merger Agreement") and the Contribution and Distribution Agreement 
among FTX, NEWCO and FRP (the "Contribution and Distribution Agreement"), 
both dated August 26, 1997, pursuant to which specified sulphur and other 
assets will be transferred from FRP and others to NEWCO.

Pursuant to the Merger Agreement, FTX will merge with and into IGL (the 
"Merger"). FTX is the Administrative Managing General Partner and Special 
General Partner of FRP. FTX and FMRP, collectively own, approximately 51.6% 
of the equity interest in FRP. FMRP is a wholly owned subsidiary of FTX, and 
is the Managing General Partner and Special General Partner of, and an equity 
owner in, FRP. IGL owns 100% of the issued and outstanding stock of IMC 
Global Operations Inc. (formerly IMC Fertilizer Inc.) ("IMC Operations").

In connection with the Merger: (1) IMC Operations intends to transfer to FRP
various 

<PAGE>

assets (collectively, the "IMC Main Pass Interests") and FRP intends to 
assume various liabilities, relating to the sulphur, oil and gas exploration 
and development operations in Main Pass Block 299, Offshore, Louisiana ("Main 
Pass") including a 25% working interest in the sulphur, oil and gas 
operations located thereon and (2) FRP intends to convey to NEWCO, various 
assets (including the IMC Main Pass Interests that FRP will acquire from IMC 
Operations and FRP's 58.3% working interest in the sulphur, oil and gas 
operations in Main Pass) and NEWCO intends to assume various liabilities, 
relating to the sulphur and certain oil and gas operations of FRP 
(collectively, the "FRP Sulphur Operations"). Following the transfer of the 
FRP Sulphur Operations to NEWCO, FRP intends to distribute the stock of NEWCO 
to its equity holders, including FTX and FMRP. FMRP intends to distribute to 
FTX the NEWCO stock it receives from FRP (the "FMRP Dividend"). As part of 
the consideration to be received by FTX stockholders in the Merger, NEWCO 
stock held by FTX prior to the Merger will be transferred to FTX 
stockholders. Collectively, the transactions described in this paragraph will 
be hereinafter referred to as the "Transaction".

Based on the foregoing description of the Transaction, Valuation has been 
asked to provide its opinion as of October 21, 1997, assuming that the entire 
Transaction has been consummated on October 21, 1997 that immediately before 
and after for FRP and FMRP, and immediately after for NEWCO, and giving 
effect to the consummation of the entire Transaction:

    (i)     The Fair Value of the aggregate assets of FRP exceeds and will
            exceed FRP's liabilities (including, without limitation, Stated
            Liabilities and Identified Contingent Liabilities).

    (ii)    The Present Fair Saleable Value of the assets of FRP exceeds and
            will exceed probable liabilities on its debts (including, without
            limitation, Stated Liabilities and Identified Contingent
            Liabilities) as such debts become absolute and mature.

    (iii)   FRP is and will be able to pay its debts, liabilities and other
            obligations (including, without limitation, Stated Liabilities and
            Identified Contingent Liabilities) as such debts, liabilities and
            other obligations become absolute and mature.

    (iv)    FRP will not have Unreasonably Small Capital with which to conduct
            its present and anticipated business.

    (v)     The Fair Value of the aggregate assets of NEWCO will exceed NEWCO's
            liabilities (including, without limitation, Stated Liabilities and
            Identified Contingent Liabilities).

<PAGE>


    (vi)    The Present Fair Saleable Value of the assets of NEWCO will exceed
            NEWCO's probable liabilities on its debts (including, without
            limitation, Stated Liabilities and Identified Contingent
            Liabilities), if any, as such debts become absolute and mature.

    (vii)   NEWCO will be able to pay its debts, liabilities and other
            obligations (including, without limitation, Stated Liabilities and
            Identified Contingent Liabilities), if any, as such debts,
            liabilities and other obligations become absolute and mature.

    (viii)  NEWCO will not have Unreasonably Small Capital with which to
            conduct its present and anticipated business.

    (ix)    FRP and FTX will not, by virtue of the Transaction, violate Section
            17-607 of the Delaware Revised Uniform Limited Partnership Act.

    (x)     The value of the Dividend does not exceed FMRP's Surplus.

    (xi)    The Fair Value of the aggregate assets of FMRP exceeds and will
            exceed FMRP's liabilities (including, without limitations, Stated
            Liabilities and Identified Contingent Liabilities).

    (xii)   The Present Fair Saleable Value of the assets of FMRP exceeds and
            will exceed FMRP's probable liabilities on its debts (including,
            without limitation, Stated Liabilities and Identified Contingent
            Liabilities) as such debts become absolute and mature).

    (xiii)  FMRP is and will be able to pay its debts, liabilities and other
            obligations (including, without limitation, Stated Liabilities and
            Identified Contingent Liabilities) as such debts, liabilities and
            other obligations become absolute and mature.

    (xiv)   FMRP will not have Unreasonably Small Capital with which to conduct
            its present and anticipated business.


<PAGE>

In addition, for purposes of the opinion set forth in item (x) on page 9, we
have assumed that:

    1.   FMRP's sole asset is 20,740 partnership units or unit equivalents of
         FRP which constitute the General Partnership Interest (as defined in
         the Amended and Restated Partnership Agreement of FRP (the "FRP
         Partnership Agreement")) which are subject to the transfer
         restrictions set forth in the FRP Partnership Agreement.

    2.   FMRP has no liabilities other than those liabilities of FRP for which
         FMRP may be responsible in its capacity as Managing General Partner
         and Special General Partner of FRP.

    3.   The assets of FRP will be available to satisfy the liabilities of FRP
         or will be available to reimburse FMRP through a right of subrogation
         if FMRP is required to satisfy the liabilities of FRP because of
         FMRP's status as a Managing General Partner and Special General
         partner of FRP.


Valuation has also been asked to provide an update of this letter as of the date
of the Merger. For the purposes of this opinion letter, the following terms are
defined:


    (a)  Present Fair Saleable Value
         The aggregate amount that may be realized by an independent willing
         seller from an independent willing buyer if the aggregate assets of
         FRP and NEWCO are sold with reasonable promptness in an arms-length
         transaction under present conditions for the sale of comparable
         business enterprises in an existing and not theoretical market. This
         definition does not contemplate a distress sale.

    (b)  Fair Value
         The amount at which the aggregate assets of each of FRP and NEWCO
         would change hands between a willing buyer and a willing seller,
         within a commercially reasonable period of time, each having
         reasonable knowledge of the relevant facts, neither being under any
         compulsion to act, with equity to both. This definition does not
         contemplate a distress sale.

<PAGE>

    (c)  Stated Liabilities
         The recorded liabilities of FRP, FMRP and NEWCO as of June 30, 1997.
         Valuation has made inquiries of management of FRP, FMRP and NEWCO (the
         "Management") and has been advised by them that there are no material
         adverse changes in the Stated Liabilities between the date of the
         information shown on such balance sheet and date of opinion.

    (d)  Identified Contingent Liabilities
         The maximum reasonably estimated liabilities that may result from
         pending litigation, asserted claims and assessments, guaranties,
         environmental conditions, uninsured risks, and other contingent
         liabilities as identified and explained to us in terms of their nature
         and estimated dollar magnitude by responsible officers of FRP and
         NEWCO. These contingent liabilities may not meet the criteria for
         accrual under Statement of Financial Accounting Standards No. 5 and
         therefore may not be recorded as liabilities under GAAP.

    (e)  Unreasonably Small Capital
         This phrase relates to the ability of each of FRP, FMRP and NEWCO,
         after giving effect to consummation of the entire Transactions, to
         continue as a going concern and not lack sufficient capital for the
         needs and anticipated needs of the operation, including Identified
         Contingent Liabilities, without substantial disposition of assets
         outside the ordinary course of business, restructuring of debt,
         externally forced revisions of its operations, or similar actions. Our
         determination of adequate capital is made from an economic rather than
         financial accounting perspective.

    (f)  Net Assets
         The amount by which total assets exceed total liabilities, including
         contingent liabilities identified to us by FMRP's management, as well
         as their respective accountants, legal advisors and financial
         advisors, and such other experts as we deemed necessary to consult,
         and valued by Valuation after consultation with responsible officers
         and employees of FMRP and/or such industry, economic and other experts
         as we deemed necessary to consult (the valuation of contingent
         liabilities to be computed in light of all the facts and circumstances
         existing at the time of such valuation as the maximum amount that can
         reasonably be expected to become an actual or matured liability).
         Capital and Surplus are not liabilities for the purposes of
         determining Net Assets.

    (g)  Capital
         The par value of the consideration received for the issuance of FMRP's
         par stock.

    (h)  Surplus
         The Fair Value of FMRP's Net Assets in excess of Capital.

<PAGE>

We believe the foregoing definitions are reasonable and appropriate for purposes
of rendering our opinions, and we believe that the methodologies we use in our
analysis are appropriate for determining Fair Value and Present Fair Saleable
Value as defined herein. Based on our inquiry, we believe it is appropriate for
us to value each of FRP and NEWCO as a going concern as part of our analysis
relating to our opinions.

In expressing its opinions, Valuation has relied, to the extent deemed
appropriate in its independent judgements, on information and analyses furnished
by and/or discussions held with FRP's management, accountants, advisors and
other experts. Information and analysis supplied by FRP's management was
reviewed and utilized to form our valuation opinions of FRP, FMRP and NEWCO.

Although Valuation does not assume any responsibility for the sufficiency and
accuracy of the information provided by FRP or NEWCO, nothing has come to
Valuation's attention in the course of this engagement which would lead it to
believe that any such information is incorrect in any material respect or that
it was unreasonable for Valuation to utilize and rely upon the information. Such
data has been accepted as reasonably reflecting the Transaction, FRP and NEWCO's
financial condition and their future operations. All items generally considered
subject to audit pursuant to generally accepted auditing standards and in
conformity with generally accepted accounting principles have been relied upon
without review, check, or verification. Nothing has come to our attention;
however, in the course of this engagement which would cause us to believe that
any information is incorrect in any material respect or that it was unreasonable
for Valuation to utilize and rely upon the information. Valuation has performed
certain analyses, studies, and investigations more fully described herein in
support of its opinions. Further, all opinions expressed herein are subject to
the General Limiting Conditions and Assumptions attached hereto as Exhibit A.

Valuation has reviewed the historical financial results of the business which
includes FRP and NEWCO, as well as extensive background data and material
considered appropriate to the opinions expressed. Such area of investigation
have included but are not limited to:


    -    Industry overviews, including an analysis of companies engaged in
         similar lines of business, as well as reviewing recent acquisitions of
         companies engaged in similar lines of business.

    -    Inquiries of Management as to the impact of future trends on FRP and
         NEWCO and also the industry, including expected demand for their
         products; estimated future levels of working capital and capital
         expenditures; competitive conditions and advantages; and key actions
         to be taken in the near term, among other factors.

         potential Identified Contingent Liabilities.

    -    Unaudited financial statements for FMRP as of September 30, 1997.

For the purposes of this opinion, Valuation has assumed that there will be no
material change in any documents in Valuation's possession on October 21, 1997.

Valuation has, to the extent necessary, discussed FRP and NEWCO and its
financial and operating matters with Management and advisors to FRP and NEWCO.
Valuation has reviewed the forecasts of earnings, cash flows, and balance sheets
of FRP and NEWCO prepared by Management and discussed, to the extent necessary,
such forecasts with Management. Nothing has come to our attention that would
cause us to believe the basic assumptions used in the forecasts are
unreasonable. We believe that the review we have conducted and the analyses and
procedures undertaken are those generally considered appropriate for expressing
the opinions herein.

<PAGE>

On the basis of the review, procedures, and analyses performed, we express the
following opinions as of the date of this letter, assuming that the entire
Transaction has been consummated on the date hereof, that immediately before and
after for FRP and FMRP, and immediately after for NEWCO, giving effect to the
consummation of the entire Transaction, all predicated on the General Limiting
Conditions and Assumptions and FRP and NEWCO continuing to operate the business
in a manner consistent with current practices, that:


    (i)     The Fair Value of the aggregate assets of FRP exceeds and will

            Liabilities and Identified Contingent Liabilities).

    (ii)    The Present Fair Saleable Value of the assets of FRP exceeds and
            will exceed FRP's probable liabilities on its debts (including,
            without limitation, Stated Liabilities and Identified Contingent
            Liabilities) as such debts become absolute and mature.

    (iii)   FRP is and will be able to pay its debts, liabilities and other
            obligations (including, without limitation, Stated Liabilities and
            Identified Contingent Liabilities) as such debts, liabilities and
            other obligations become absolute and mature.

    (iv)    FRP will not have Unreasonably Small Capital with which to conduct
            its present and anticipated business.

    (v)     The Fair Value of the aggregate assets of NEWCO will exceed NEWCO's
            liabilities (including, without limitation, Stated Liabilities, and
            Identified Contingent Liabilities).

    (vi)    The Present Fair Saleable Value of the assets of NEWCO will exceed
            NEWCO's probable liabilities on its debts (including, without
            limitation, Stated Liabilities and Identified Contingent
            Liabilities), if any, as such debts become absolute and mature.

    (vii)   NEWCO will be able to pay its debts, liabilities and other
            obligations (including, without limitation, Stated Liabilities and
            Identified Contingent Liabilities), if any, as they such debts,
            liabilities and other obligations become absolute and mature.

    (viii)  NEWCO will not have Unreasonably Small Capital with which to
            conduct its present and anticipated business.

    (xii)   The Present Fair Saleable Value of the assets of FMRP exceeds and
            will exceed FMRP's probable liabilities on its debts (including,
            without limitation, Stated Liabilities and Identified Contingent
            Liabilities) as such debts become absolute and mature).

    (xiii)  FMRP is and will be able to pay its debts, liabilities and other
            obligations (including, without limitation, Stated Liabilities and
            Identified Contingent Liabilities) as such debts, liabilities and
            other obligations become absolute and mature.

    (xiv)   FMRP will not have Unreasonably Small Capital with which to conduct

This letter is solely for the information and assistance to the parties to whom
it is addressed for matters in connection with the proposed Transaction,
including disclosing the final opinion in any Proxy Statement or Prospectus. Any
other use is expressly prohibited and neither this letter nor any of its parts
may be circulated, quoted, or otherwise referred to for any other purpose
without the written consent of Valuation, the exercise of which will be at the
sole discretion of Valuation not unreasonably withheld. If given, such consent
shall not be without sufficient review by Valuation as to the precise language
of such disclosure and the time and place of its potential release.

The above limitations do not apply to related parties who you believe have a
legitimate business interest in receiving such copies, including counsel,
potential and participating lenders, courts, administrative agencies, the
persons and entities to whom disclosure is permitted under the General Limiting

additional lenders, successors, or appropriate parties involved in litigation or
court proceedings involving this Transaction or under other similar
circumstances.

                                      EXHIBIT A

                     GENERAL LIMITING CONDITIONS AND ASSUMPTIONS


In accordance with recognized professional standards as generally practiced in
the valuation industry, the fee for these services is not contingent upon the
conclusions of value contained herein. Valuation has determined to the best of
its knowledge and in good faith that neither it nor any of its agents or
employees have a material financial interest in FRP or NEWCO.

Neither Valuation, nor its agents or employees, assume any responsibility for
matters legal in nature, nor do they render any opinion as to any title to, or
legal status of, property which may be involved, both real and personal,
tangible and intangible.

Valuation assumes that all laws, statutes, ordinances, or other regulations, or
regulations of any governmental authority relevant to and in connection with
this engagement are complied with unless express written noncompliance is
brought to the attention of Valuation and is stated and defined by those relied
on by Valuation.

Valuation has relied on certain information furnished by others, including but
not limited to FRP and NEWCO, without verification, other than the procedures
specified in Valuation's letter attached hereto. Valuation believes such
information to be reliable as to accuracy and completeness but offers no
warranty or representation to that effect; however, nothing has come to our
attention in the course of this engagement that would cause us to believe that
any information is inaccurate in any material respect or unreasonable to utilize
and rely upon such information.

Valuation assumes in the case of leases of real and other property that this
transaction will not trigger any renegotiations of such leases to market rates
based upon the change in the financial condition of the properties leased by the
Borrower arising out of this Transaction that would, in aggregate, be material
to the Borrower. Based upon inquiries in connection with this matter, we have no
reason to believe that there will be any material adverse effect on FRP or NEWCO
arising from the consummation of the Transaction.

In some instances, public information and statistical information have been
obtained from sources Valuation has accepted as being reliable; however,
Valuation makes no representation as to the accuracy or completeness of such
information and has accepted the information without further verification.
However, nothing has come to our attention in the course of this engagement that
would cause us to believe that any such information is inaccurate in any
material respect.


The opinion of Valuation does not represent an assurance, guarantee, or warranty
that FRP or NEWCO will not default on any debt obligations or covenants
associated with the Transaction.

<PAGE>

Valuation has analyzed and reviewed the Transaction and provided an opinion for
the purposes set forth in this letter only and for no other purpose. Valuation's
opinion is in no way given as an indication of the fairness of the Transaction
to any shareholder of FRP or NEWCO or any other participant in the Transaction. 

The opinions expressed herein are valid only for the express and stated purposes
of providing information and assistance to the parties to whom it is addressed
and their specific agents engaged in conducting and documenting their
independent investigations concerning FRP and NEWCO and are not in any way,
implied or expressed, to be construed, used, circulated, quoted, relied upon or
otherwise referred to for any other purpose, except as set forth in the Opinion
to which these General Limiting Conditions and Assumptions are attached.

In addition, Valuation hereby consents to (i) the filing and disclosure of the
Opinion with the Securities and Exchange Commission (the "SEC") and any state
securities commission or blue sky authority, or other governmental authority or
agency if such filing or disclosure is required pursuant to the rules, statutes,
and regulations thereof, or required by applicable law, (ii) the disclosure of
the Opinion upon demand, order or request of any court, administrative or
governmental agency, regulatory body or examiner (whether or not such demand,
order or request has the force of law) or as may be required or appropriate in
response to any summons, subpoena, or discovery requests, (iii) the use or
disclosure of the Opinion in any pending or threatened litigation, judicial, or
administrative proceeding (including, without limitation, any proceeding in
bankruptcy) or inquiry, or government investigation, (iv) the attachment of the
Opinion as an exhibit to the Merger document or as an exhibit to any documents
related to the Transaction, (v) the disclosure of the Opinion in connection with

In preparing this Solvency Opinion, Valuation conducted certain procedures and
analysis which have been described in the body of this opinion. In order to
render such an opinion, Valuation developed a range of valuation conclusions
with respect to FRP and NEWCO's assets. The range of indicated values was
arrived at through the use of generally accepted valuation procedures. These
procedures included the Income Approach, and Market Approach as both such
approaches are defined in forthcoming paragraphs which we believe to be
procedures appropriate to express the opinions herein.

The Income Approach utilized cash flow projections discounted to a present
value. The discount rate selected was based on risk and return requirements
deemed appropriate by Valuation, given the facts and circumstances surrounding
the Transaction under consideration. In arriving at an appropriate discount
rate, Valuation considered FRP's weighted average cost of capital, the weighted
average cost of capital for other companies in the industry, and the rate of
return on alternative investments. In addition, the risk inherent in the
business was also considered.

In addition to discounting the projected cash flows of FRP and NEWCO, Valuation
performed sensitivity analysis which included varying the discount rates, sales
growth rates, and profit margins of the projections in estimating a range of
values.

The Market Approach compared the subject company with publicly-traded companies
engaged in businesses which Valuation deemed reasonably similar to the
subject's. The companies selected were either competitors of FRP and NEWCO or
operating in the same industry. Ratios such as invested capital to earnings
before interest and taxes; invested capital to earnings before interest,
depreciation, and taxes; invested capital to sales; and invested capital to debt
free net income were employed. Recent acquisitions of sulphur companies or
companies in related industries were also reviewed.

Our opinion is necessarily based on economic, market, financial and other
conditions as they exist on the date of this letter. While various judgments and
estimates which we consider reasonable and appropriate under the circumstances
were made by us in the determination of value, no assurance can be given by us
that the sale price which might ultimately be realized in any actual
transaction, if and when effected, will be at the Present Fair Saleable Value or
Fair Value concluded in our analysis.

<PAGE>

Our conclusions of Present Fair Saleable Value and Fair Value of assets are for
the aggregate or total assets of FRP and NEWCO. Nothing has come to our
attention which would cause us to believe that the Present Fair Saleable Value
of the aggregate assets is materially different from the Fair Value of such
aggregate assets.

Valuation has discussed Identified Contingent Liabilities with representatives
of FRP, FMRP and NEWCO, respectively. FRP, FMRP and NEWCO have advised Valuation
that there are no other outstanding claims or proceedings or other contingent
liabilities that, in the aggregate would materially affect the financial
position of FRP, FMRP, or NEWCO. The respective officers of FRP, FMRP and NEWCO
expressed their opinions that adequate provisions for contingent liabilities
have been made by insurance or accrual or that the ultimate cost resulting from
such liabilities will not materially affect the financial position of FRP, FMRP
and NEWCO. Valuation expresses no opinion as to the completeness or adequacy of
Identified Contingent Liabilities but nothing has come to Valuation's attention
which would lead it to believe that such estimates are unreasonable.

Valuation has made inquiries of the management of FRP and NEWCO and been advised
that there has been no material adverse change in the financial position of FRP
and NEWCO (except for any changes related to the Transaction between June 30,
1997 and October 21, 1997. 

Material changes in the industry or in market conditions which might affect FRP
and NEWCO's business from and after the effective date of the proposed
Transactions and which are not reasonably foreseeable are not taken into
account.
