         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

                   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.

              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*].

<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.
