     5.   General Operating Principles for the Aniline Facilities
          -------------------------------------------------------

          The general operating principles concerning the entitlement of the
Users with respect to products resulting from Rubicon's operation of the Aniline
Facilities (and in this Section 5 the term "products" shall mean only those
resulting from the operation of the Aniline Facilities), the requirements with
respect to furnishing benzene, the allocation and payment of Rubicon's operating
costs with respect to the Aniline Facilities (and in this Section 5 the term
"operating costs" shall mean only those incurred with respect to the Aniline
Facilities), and the consequences of a User's failure to order products or to
furnish benzene, shall be as stated below.

          The other provisions of this Section 5 and elsewhere in this Operating
Agreement to the contrary notwithstanding, the parties recognize that the
production of TDA and DNT requires the use of certain facilities in the aniline
plant and the nitrobenzene plant and, as hereinafter set forth, the sulfuric
acid plant, in addition to the TDA/ DNT plant.  During those periods in which
the operation of the sulfuric acid plant is not required relative to the
production of aniline for the Users it will be operated solely for the
production of DNT and all the costs, including variable, constant and capital
based costs, incurred by Rubicon for the operation of the sulfuric acid plant
during such periods shall be allocated to and paid by RCI.  During

                                       11


any period in which part or all of the sulfuric acid plant's operation is
required for the production of aniline as well as DNT and at all times with
respect to the operation of the aniline plant to produce aniline and the
nitrobenzene plant to produce nitrobenzene, as well as in part for the
production of DNT, all operations for the production of DNT shall be deemed to
be production of aniline or nitrobenzene, as appropriate, for ICI-AM for
purposes of determining the respective entitlements of the Users to products
resulting from the operation of the Aniline Facilities, and for purposes of
allocating to the Users the variable, constant and capital based costs incurred
by Rubicon for the operation of the Aniline Facilities in accordance with this
Section 5. ICI-AM shall determine and instruct Rubicon to what extent production
capacity available for it shall be used for aniline, nitrobenzene or DNT and to
what extent any costs allocated to it shall be paid by RCI.

          5.1. Entitlement to Products
               -----------------------

          (a)  Before the end of each month, Rubicon shall advise the Users as
     to its estimate of the maximum quantity of each product which can result
     from Rubicon's operations in each day of the following month.

          (b)  On a specified day in each month, each User shall be entitled to
     order produced for it during each day in the following month a quantity of
     each product up to

               (i)   such User's ("the first User") percentage entitlement to
                     such estimated maximum quantity of each product, plus

               (ii)  that portion, if any, of such estimated maximum quantity
                     not ordered by the other User (the "second User") which,
                     together with the quantity determined under (i), will not
                     result in the first User's receiving a quantity of product
                     for the year-to-date period in excess of the first User's
                     percentage entitlement to the Rated Capacity for such
                     product for such year-to-date period, plus

               (iii) any remaining portion of the second User's unused
                     percentage entitlement to such maximum estimated quantity
                     which the second User agrees to make available to the first
                     User for such day.

                                       12


          (c)  Thereafter, either User may increase or decrease its order for
     each product for any day on reasonable notice to Rubicon and such User's
     order as last so revised shall become the existing order of such User, but
     any increase shall be taken into account only to the extent that a capacity
     to produce such product in excess of that last ordered by both Users for
     that day shall become available for such day and shall be within the
     quantity of such product which the User seeking an increase would be
     entitled to order under subparagraph (b) above.

          (d)  Rubicon shall promptly advise both Users of the aggregate
     existing orders for products.

          (e)  The available quantity of each product shall be allocated between
     the Users each day in accordance with the following:

               (i)  when the quantity available is equal to or greater than the
                    aggregate quantity ordered by both Users, the quantity
                    available shall be allocated between the Users in proportion
                    to their respective existing orders, but

               (ii) when the quantity available is less than the aggregate
                    quantity of both Users' existing orders, the quantity
                    available shall be allocated between the Users as follows:

                         first, there shall be allocated to each User the
                    quantity of its existing order, or such User's percentage
                    entitlement of the quantity available, whichever is less,
                    and

                         then, the remaining quantity available, if any, shall
                    be allocated to the User to which there was allocated in the
                    first step above less than the quantity of such User's
                    existing order.

          (f)  If either User fails to furnish Rubicon enough benzene, or to
     leave available enough intermediate product necessary for production of
     another product, and thus limits the quantity of a given product which
     Rubicon can produce on a given day for such User to less than the quantity
     to which such User otherwise would have been entitled, then the available

                                       13


     quantity of that product produced shall be allocated between the Users for
     that day in proportion to the limiting benzene or intermediate product
     furnished, or left available, by each User for that day.

          (g)  Each User shall have the right to specify how much, if any, of
     the available quantity of each product allocated to such User for each day
     is to be delivered to or on behalf of such User outside the Aniline
     Facilities, and how much, if any, is to be used for production of another
     product.

          (h)  If, through any circumstance, a quantity of a given product which
     should have been allocated to or delivered to or on behalf of one User
     ("the first User") for a given day is in fact allocated to or delivered to
     or on behalf of the other User ("the second User") for such day, Rubicon
     shall promptly notify the first User and shall adjust subsequent
     allocations or deliveries of such product between the Users so as to
     correct the variance in allocation or delivery at the earliest opportunity,
     but if Rubicon fails to correct such variance during the month in which it
     is discovered, the variance shall be corrected at the earliest opportunity
     thereafter only if and to the extent that the first User shall request it,
     in which event the quantity of such product returned to the first User
     shall be taken from the quantity of such product allocable to the second
     User pursuant to subparagraphs (e) and (f) above.

          (i)  If one User ("the first User") has availed itself of product
     storage space in any portion of the other User's ("the second User")
     entitlement to product storage space and if, solely as a consequence of
     lack of product storage space for the second User, Rubicon is unable to
     produce all of the second User's ordered product, then

               (i)  there shall be deemed to have been produced for the second
                    User and transferred from the stored product of the first
                    User a quantity equal to the second User's order for product
                    which could not, for this reason, be produced; and

               (ii) if the product so transferred is nitrobenzene or aniline, it
                    shall be deemed to have been produced from benzene belonging
                    to the second User.

                                       14


          (j)  Any by-product, except high pressure steam resulting from the
     operation of the nitric acid plant and low pressure steam (approximately 30
     psig) resulting from the operation of the integrated aniline plant,
     resulting from the operation of the Aniline Facilities shall, at no
     additional charge to the Users, be delivered to or on behalf of the Users
     in the same ratios as the product to which the by-product relates.

          5.2. Furnishing Benzene to Rubicon
               -----------------------------

          (a)  Each User shall furnish to Rubicon the quantity of benzene
     meeting the specifications set forth in Exhibit E required by Rubicon in
     the operation of the Aniline Facilities for such User. The provisions of
     any agreement by Rubicon to defend and indemnify the Users with respect to
     benzene shall not be deemed or construed as a release or waiver by Rubicon
     of its rights hereunder.

          (b)  The furnishing of benzene shall be determined in accordance with
     the following rules.

               (1)  A User's benzene shall be deemed to be furnished to Rubicon
          within the meaning of paragraph (a) immediately above and subparagraph
          (2) immediately below when such benzene has been delivered to the
          vicinity of Rubicon's property and is within its control, even though
          such benzene has not yet been transferred into Rubicon's benzene
          storage facility.

               (2)  If one User ("the first User") has availed itself of benzene
          unloading facilities or benzene storage space in any portion of the
          other User's ("the second User") entitlement to unloading facilities
          or benzene storage space when the second User has furnished benzene to
          Rubicon as provided in (1) above, then

                    (i)  any demurrage charges incurred by the second User (with
               respect to any vessel, tank car or tank truck holding benzene) as
               a result of the first User's use of such portion of benzene
               unloading facilities or benzene storage space shall be paid for
               by the first User; and

                                       15


                    (ii) the benzene of the first User which occupies such
               portion of the benzene unloading facilities or benzene storage
               space shall be deemed exchanged for an equal amount of benzene of
               the second User but only if and to the extent that Rubicon
               requires such amount of benzene to fill the second User's ordered
               quantity of product.

          5.3  Uniroyal's Option to Furnish Ammonia to Rubicon
               -----------------------------------------------

          (a) Uniroyal may, at any time and from time to time, furnish to
     Rubicon for use in the nitric acid plant, and Rubicon shall accept for such
     use, any ammonia which results from the operation of the DPA plant for
     Uniroyal and which meets the ammonia specifications set forth in Exhibit F,
     provided that such purchase by Rubicon shall not violate any existing
     Rubicon contract for the purchase of ammonia or require the payment by
     Rubicon of any liquidated damages under any such contract.

          (b) Rubicon shall pay, or credit, Uniroyal for such ammonia the lowest
     most recent net price to Rubicon (f.o.b. supplier) of ammonia otherwise
     purchased by Rubicon.

          (c) At Uniroyal's request, Rubicon shall, in accordance with paragraph
     3.4 of this Operating Agreement, acquire and operate such additional
     facilities as Uniroyal may specify so that ammonia from the DPA plant will
     meet the applicable specifications for ammonia, and such facilities shall
     be included in the definition of the DPA plant for all purposes under this
     Agreement.

          5.4  Use and Delivery of Low Pressure Steam
               --------------------------------------

          Rubicon shall, as and to the extent requested by Uniroyal, deliver to
Uniroyal, at the property line between Rubicon and Uniroyal, at the property
line between Rubicon and Uniroyal, up to that quantity of the low pressure steam
(approximately 30 psig) generated by the Aniline Facilities as exceeds the
aggregate quantity of such low pressure steam (i) which is utilized by Rubicon
in the Aniline Facilities plus (ii) which is delivered to RCI or the other
Rubicon facilities as provided in the following two sentences.  Rubicon shall,
as and to the extent requested by RCI, deliver up to 15,000 lbs. per hour for
use in the MDI plant and up to 10,000 lbs. per hour for use in the TDI plant of
such low pressure steam.  As and to the extent authorized in specific
appropriation requests approved by its Board of

                                       16


Directors, Rubicon shall make additional quantities of such low pressure steam
available for delivery to and use in Rubicon facilities, other than the Aniline
Facilities, and in the RCI plants. Uniroyal and RCI shall, until December 25,
1983, pay to Rubicon, and, until such date, Rubicon shall charge to any of its
facilities, including the Aniline Facilities, utilizing such low pressure steam,
for each pound of such steam so delivered and utilized in each month, a price
equal to 0.80 of the average total constant (excluding any constant cost
resulting from the basic charge referred to in subparagraph 5.2(b) of the
Utilities Services Agreement) and variable costs incurred by Rubicon in
accordance with Exhibit A for each pound of 600 psig steam purchased by Rubicon
from Uniroyal in such month, and after such date a price equal to 0.70 of such
costs. Rubicon shall apply such payments from Uniroyal and RCI and such charges
to its facilities in reduction of Rubicon's variable costs incurred with respect
to the production of aniline.

          5.5  Use of High Pressure Steam from Nitric Acid Plant
               -------------------------------------------------

          Rubicon shall utilize high pressure steam generated by the nitric acid
plant in its other operations and reduce purchases of steam from Uniroyal or
other sources accordingly.  Rubicon shall charge to the variable cost of the
operations utilizing such steam, for each pound of steam so utilized in each
month, an amount equal to the average total constant and variable costs incurred
by Rubicon in accordance with Exhibit A for each pound of 600 psig steam
purchased by Rubicon from Uniroyal in such month, and shall apply the amount of
such charges in reduction of Rubicon's variable cost incurred with respect to
the operation of the nitric acid plant.

          5.6  Allocation and Payment of the Operating Costs of the
               Aniline Facilities
               ----------------------------------------------------

          (a) The operating costs of the Aniline Facilities consist of Rubicon's
     pre-operational and start-up, variable, constant and capital based costs
     allocated to the Aniline Facilities in accordance with Exhibit A.

          (b) The variable costs incurred by Rubicon with respect to each plant
     within the Aniline Facilities shall be allocated to and paid by the Users
     on an equal per-unit-of delivered product basis, calculated on an average
     year-to-date basis.

          (c) Except as otherwise provided in subparagraph (d) below and in the
     second paragraph of the preamble to this Section 5, the pre-operational

                                       17


     and start-up costs, the constant costs and the capital based costs incurred
     by Rubicon with respect to each plant within the Aniline Facilities shall
     be allocated between and paid by the Users in proportion to their
     respective percentage entitlements to product from such plant.

          (d) To the extent that there is allocated to a User ("the first User")
     for any year-to-date period a quantity of product in excess of the greater
     of:

              (i)  the quantity derived by multiplying Rubicon's Rated Capacity
          for such product, pro-rated to such year-to-date period, by the first
          User's percentage entitlement to such product, or

              (ii) the quantity derived by multiplying the aggregate quantity
          of such product allocated to both Users for such year-to-date period
          by the first User's percentage entitlement to such product,

     the first User must pay to Rubicon, in addition to the costs allocated to
     the first User pursuant to subparagraph (c) above, the year-to-date
     constant and capital based costs attributable to such excess quantity of
     such product during such year-to-date period, and the constant and capital
     based costs allocated to the other User shall be reduced accordingly, which
     shall be final only if and to the extent any such excess quantity of such
     product is allocated to the first User as of the end of a year.

          (e) The Rated Capacity of each plant within the Aniline Facilities
     shall be expressed in pounds of product per year extrapolated from a
     performance test to be conducted by Rubicon.

              (1) The performance test shall be conducted

                  (i)  as soon as practicable following the debugging of the
                       integrated aniline plant, and

                  (ii) annually thereafter at a time mutually agreed upon by
                       the Users.

              (2) Unless otherwise agreed by the Users from time to time, the
          performance test shall consist of operating each plant within the
          Aniline Facilities at full possible production rates for 24 hours per
          day for a period of 7 consecutive days (the "test period") and noting

                                       18


          the production results and operating conditions for each plant within
          the Aniline Facilities during the test period.  If during any portion
          of any day within the test period a plant should not operate at its
          full possible production rate (such portion of such day hereinafter
          called "down time"), the production results obtained for such plant
          during the down time shall be eliminated, and the down time shall be
          eliminated from the test period for such plant.  The adjusted
          production results (expressed in pounds of production) when divided by
          the adjusted test period (expressed in days) for each plant and
          multiplied by 330 days shall be the Rated Capacity of such plant.

               (3) Rubicon shall submit to the Users Rubicon's detailed plan for
          conducting each performance test, and Rubicon shall not conduct such
          test until the plan has been approved by the Users.  Any adjustments
          resulting from eliminations for down time made by Rubicon in
          accordance with subparagraph (2) immediately above shall be subject to
          the approval of the Users.  Each User shall have the right to have its
          representatives observe the performance test and receive the results
          obtained therefrom.

          5.7  Consequences of Failure of the Users to Order
               Products or to Furnish Benzene
               ---------------------------------------------

          The only consequences of a User's failure to order products from
Rubicon or to furnish to Rubicon the quantity and quality of benzene required by
Rubicon in the operation of the Aniline Facilities shall be that

               (i)  the quantities of products and by-products, if any,
          allocated to such User shall be correspondingly reduced; and

               (ii) such User shall nevertheless pay to Rubicon that portion of
          Rubicon's operating costs for the Aniline Facilities allocated to such
          User.

                                       19


     6.   General Operating Principles for the DPA Plant
          ----------------------------------------------

          6.1  Operation of the DPA Plant
               --------------------------

          (a) Rubicon shall operate the DPA plant solely for Uniroyal, and shall
     deliver to or on behalf of Uniroyal all DPA, ammonia and any other
     by-product resulting from the operation of the DPA plant.

          (b) Before the end of each month, Rubicon shall advise Uniroyal as to
     Rubicon's estimate of the maximum quantity of DPA which can result from
     Rubicon's operation in each day of the following month.

          (c) On a specified day in each month, Uniroyal shall be entitled to
     order DPA produced for it in each day in the following month up to such
     maximum quantity, and thereafter may increase or decrease its order for DPA
     for any day on reasonable notice to Rubicon, but any such increase shall be
     taken into account only to the extent that a quantity of DPA in excess of
     that previously ordered by Uniroyal for that day can result from Rubicon's
     operation in such day.

          6.2  Furnishing Aniline to Rubicon
               -----------------------------

          Uniroyal shall furnish to Rubicon the aniline required by Rubicon to
operate the DPA plant out of Uniroyal's allocation of aniline produced by
Rubicon or from any other source.

          6.3  Allocation and Payment of the Operating Costs of
               the DPA Plant
               ------------------------------------------------

          The operating costs of the DPA plant consist of Rubicon's
pre-operational and start-up, variable, constant and capital based costs
allocable to the DPA plant in accordance with Exhibit A. The operating costs of
the DPA plant shall be allocated to and paid by Uniroyal.

                                       20


          6.4  Consequences of Failure of Uniroyal to Order DPA
               or Furnish Aniline
               ------------------------------------------------

          The only consequences of Uniroyal's failure to order DPA from Rubicon
or to furnish to Rubicon the quantity of aniline required by Rubicon in the
operation of the DPA plant shall be that

               (i)  the quantity of DPA produced for Uniroyal shall be
          correspondingly reduced; and

               (ii) Uniroyal shall nevertheless pay to Rubicon all of Rubicon's
          operating costs for the DPA plant.

     7.   Rubicon's Operation of the Off-sites
          ------------------------------------

          7.1  Rubicon shall operate the Off-sites as required to provide the
necessary and appropriate services for all its facilities and for the RCI
plants.

          7.2  (a)  The operating costs of the Off-sites consist of Rubicon's
     pre-operational and start-up, constant and capital based costs allocated to
     the Off-sites in accordance with Exhibit A.

               (b) The operating costs incurred by Rubicon with respect to each
     of the Off-sites shall be allocated first to the plants or to other Off-
     sites and then to the plants, and then shall be allocated among and paid by
     the Users and RCI, as provided in Exhibit A.

     8.   Rubicon's Operation of the Waste Disposal Plant
          -----------------------------------------------

          8.1  Rubicon shall operate the waste disposal plant to treat and
dispose of only acceptable liquid waste generated by the operation of its
facilities for the Users and the RCI plants for RCI, all as provided in this
Operating Agreement.

          8.2  The total present capability of the deep well portion of the
waste disposal plant to dispose of liquid waste is estimated, as of the date of
this Operating Agreement, to be 455 gallons per minute.  The parties have agreed
that ICI-AM shall be entitled to 80% and Uniroyal shall be entitled to 20% of
the flow capacity of the waste disposal plant (the respective WD percentage
entitlements). The usage of the flow capacity of the waste disposal plant for
the RCI plants shall be deemed to be usage thereof by, and shall be charged to
the WD percentage entitle-

                                      21


ment of, ICI-AM, and ICI-AM shall determine the usage of its WD percentage
entitlement as between the RCI plants and the Aniline Facilities as operated for
it. If, for any reason, the present deep wells are incapable of fulfilling the
waste disposal requirements of the Users and RCI, the provisions of Section 15
shall apply to any increase of waste disposal capability which may be proposed.

          8.3  Except as provided in paragraph 8.4, the respective
responsibilities of the Users for the fixed capital of the waste disposal plant
shall be in their respective WD percentage entitlements. As a result of the
agreement to establish the respective WD percentage entitlements at 80% and 20%,
ICI-AM will increase its F.C.F. Commitment and Term Loan to Rubicon, plus pay to
Uniroyal, an aggregate amount of $120,000, divided as appropriate between such
increases and such payment, and Uniroyal's F.C.F. Commitment and Term Loan to
Rubicon shall be reduced by an amount corresponding to the ICI-AM increases in
its Commitment and Loan.

          8.4  (a)  In the event the capacity to produce any product is expanded
     or a production process is changed by Rubicon or RCI and such expansion or
     change results in an increased flow of liquid waste to be disposed of by
     the waste disposal plant but is within the disposal capacity of the deep
     well and is within the WD percentage entitlement of the User or Users
     causing such expansion or change (including the waste from the RCI plants
     in ICI-AM's WD percentage entitlement) but will require an addition or
     expansion of any or all of the ancillary facilities for accumulation,
     pretreatment and injection, then, Rubicon shall proceed with the design and
     construction of such ancillary facility addition or expansion using such
     design and such contractor or contractors as shall be determined by
     Rubicon's Board of Directors.

               (b) The allocation of the fixed capital responsibility for each
     such ancillary facility addition or expansion shall be determined at the
     time it is authorized by Rubicon's Board of Directors.  The appropriation
     request which is approved by Rubicon's Board of Directors covering each
     such addition or expansion shall identify the purpose for its installation,
     including which plant or plants have, directly or indirectly, the need for
     such addition or expansion at that time and, if two or more plants have
     such need, the best engineering estimates at that time of the relative
     proportions of such needs between or among such plants.  For purposes of
     making the allocations of responsibility for the fixed capital for each
     such addition or expansion, the

                                       22


     need or needs as so determined shall be the expected use (projected in good
     faith as and to the extent reasonably able to be anticipated at that time
     and acceptable to Rubicon's Board of Directors), directly or indirectly, of
     such addition or expansion. Fixed capital responsibility allocated to one
     or more of the RCI plants shall be allocated to ICI-AM. Each User shall
     furnish the financing for the fixed capital for which it is so allocated
     responsibility in the manner and on the terms set forth in the Financing
     Agreement.

          8.5  The operating costs of the waste disposal plant consist of
Rubicon's pre-operational and start-up, constant and capital based costs
allocated to the waste disposal plant in accordance with Exhibit A. The
operating costs incurred by Rubicon with respect to the waste disposal plant
shall be allocated between and paid by the Users as provided in Exhibit A;
provided, however, that ICI-AM may direct that some portion of its allocation be
reallocated to and paid by RCI.

     9.   General Obligations of Rubicon with Respect to the RCI Plants
          -------------------------------------------------------------

          9.1  Operation of the RCI Plants
               ---------------------------

          (a) Rubicon shall, in accordance with this Operating Agreement, as an
     independent contractor, operate the RCI plants, solely for the benefit of
     RCI and as directed by RCI consistent with this Operating Agreement, to
     produce RCI products. Except for aniline to be furnished by RCI, all
     utilities, labor, materials and services required to operate the RCI plants
     to produce RCI products shall be furnished by Rubicon. Rubicon shall

               (i)  deliver to or on behalf of RCI the products and by-products,
          if any, resulting from the operation of the RCI plants, and

               (ii) allocate to, and collect from, RCI the costs incurred by
          Rubicon in its facilities and for utilities, labor, materials and
          services provided by Rubicon for the operation of the RCI plants and
          allocated to RCI in accordance with the procedures contained in this
          Operating Agreement.

          (b) Rubicon shall supervise and cause to be made such additions to,
     modifications of or improvements in the RCI plants as may be specified by
     RCI and make or cause to be made such other normal maintenance and

                                       23


     improvement expenditures as shall be approved or directed by RCI.  RCI
     shall directly pay for all expenditures incurred for these purposes.

          9.2  Allocation and Payment of Rubicon's Operating Costs
               with Respect to the RCI Plants
               ---------------------------------------------------

          Rubicon's operating costs with respect to the RCI plants consist of
those of Rubicon's pre-operational and start-up, variable, constant and capital
based costs allocated to the RCI plants in accordance with Exhibit A, it being
understood that, in view of the fact that RCI owns and has financed and shall
finance directly all fixed capital investment in the RCI plants, Rubicon shall
have no capital based costs with respect to the RCI plants themselves.
Rubicon's operating costs for the RCI plants shall be allocated to and paid by
RCI.

          9.3  Termination of Rubicon's Operation of the RCI Plants
               ----------------------------------------------------

          (a) On reasonable notice to Rubicon, RCI may terminate Rubicon's
     operation of the RCI plants and any other facilities then owned by RCI and
     operated by Rubicon in accordance with this Operating Agreement. Following
     the effective date of such termination, Rubicon will cease operating the
     RCI plants and such other facilities, and will cease furnishing management,
     staff, labor and materials to operate the RCI plants to produce RCI
     products. Thereupon the provisions of paragraph 9.1 (except for
     subparagraph 9.1(a)(ii)) shall no longer be applicable.

          (b) Notwithstanding the provisions of subparagraph 9.3(a), unless the
     parties hereto shall otherwise agree,

               (i)  Rubicon shall continue to furnish to RCI for the operation
                    of the RCI plants those substances, utilities and services
                    from certain of the Off-sites, the waste disposal plant and
                    purchased from others then being furnished by Rubicon,

               (ii) Rubicon shall continue to allocate the operating costs
                    thereof to RCI in accordance with this Operating Agreement
                    (which allocations to RCI, as to constant costs, shall be
                    (1) of Rubicon's remaining constant costs, i.e. after
                    reductions thereof, if any, resulting from such termination,
                    following the same principles as set forth in paragraph
                    17.2 with respect to constant costs allocations in

                                       24


                     the event of a plant shutdown, (2), on the same bases as
                     such constant costs would have been allocated to the RCI
                     plants and then to RCI as though such termination had not
                     occurred, e.g., allocations based on direct labor will
                     reflect RCI's employees as though they were employees of
                     Rubicon), and

               (iii) RCI shall pay such costs.

          9.4  Consequences of Failure of RCI to have Rubicon
               Operate the RCI Plants
               ----------------------------------------------

          While Rubicon is operating the RCI plants or after the termination of
such operation, the only consequences under this Operating Agreement of RCI
failing to have the RCI plants operated shall be that RCI shall nevertheless pay
to Rubicon that part of Rubicon's operating costs for the RCI plants allocated
to RCI.

     10.  External Assets
          ---------------

          10.1 RCI and Rubicon, respectively, shall provide the financing for,
and pay the operating costs of, their respective External Assets.

          10.2 RCI and Rubicon hereby grant, each to the other, for as long as
may be necessary, an easement on their respective real properties at Geismar,
Louisiana for the installation, operation, repair and maintenance of their
respective External Assets.  If at any time, and from time to time, for any
significant reason it becomes necessary or desirable to do so, each party will
execute and deliver to the other, in recordable form acceptable to counsel for
the receiving party, documentary evidence covering one or more easements with
respect to one or more External Assets.

          10.3 The ownership of External Assets will be determined by the
respective books and records of RCI and Rubicon, which, in the absence of error
or negligence, shall be the final determination of ownership and valuation.
External Assets will remain the property of the owning party notwithstanding the
fact that they are permanently affixed to, or interconnected with, the real or
personal property of the party on whose property they are located.

          10.4 In the event RCI exercises its right to terminate Rubicon's
operation of the RCI plants as provided in paragraph 9.3, RCI and Rubicon,
respec-

                                       25


tively, will nevertheless continue to operate the other's External Assets as and
to the extent requested by the other.

     11.  Expansion of Capacity to Produce Aniline
          ----------------------------------------

          11.1 If at any time and from time to time either User desires that
Rubicon expand its then existing capacity to produce aniline, then in each such
instance the provisions of this Section 11 shall apply.  The User proposing such
expansion (the "first User") shall so notify the other User (the "second User")
in writing, which notification shall state in detail the Design Expansion
Capacity desired by the first User, the cost and timing of the proposed
expansion, and, if other than by Rubicon's then current process, the proposed
process (disclosure of which process to the second User may require execution by
the second User of appropriate agreements for confidentiality) , as well as any
other information the second User may reasonably request.  The Users shall then
consult together to consider this proposal.  Within 90 days following its
receipt of such notification and all such information, the second User shall
elect in writing whether it desires to participate in such proposed expansion,
specifying, if it wishes to participate, the Design Expansion Capacity of
aniline it desires.  Failure by the second User to make any election within said
period shall be deemed an election by it not to participate in such expansion.
If both Users desire to participate in such expansion, the Design Expansion
Capacity of such expansion shall be the combination of the Design Expansion
Capacities desired by both Users.

          11.2 Upon completion of said notification, information, consultation
and election procedures, and provided that the User or Users participating in
such expansion furnish all of the financing for the fixed capital for such
expansion in the manner and on the terms set forth in the Financing Agreement,
Rubicon shall proceed with the design and construction of such expansion, using
such process as is then available, or is made available by the User or Users
participating in such expansion, to Rubicon, and such contractor or contractors
as shall be designated by the participating User or Users, which process and
contractor or contractors must be reasonably acceptable to Rubicon's Board of
Directors.  The Users' respective responsibilities for the fixed capital for
such expansion and for the financing thereof shall be in their respective
Expansion Percentages.

          11.3 If both Users participate in such expansion and their respective
Expansion Percentages are the same as their respective pre-expansion percent-

                                       26


age entitlements, then the provisions of the following paragraphs of this
Section 11 shall not apply.

          11.4 If only one User participates in such expansion or if both Users
participate but their respective Expansion Percentages are different from their
respective pre-expansion percentage entitlements, and, in either such event, for
all expansions of capacity to produce aniline thereafter, then the provisions of
this paragraph 11.4 and the following paragraphs of this Section 11 shall apply.
Prior to the commencement of construction of each such expansion, Rubicon shall,
utilizing the procedures set forth in subparagraph 5.6(e) of this Operating
Agreement, conduct a performance test of each plant within its then existing
Aniline Facilities to determine the Pre-Expansion Rated Capacity thereof. Upon
Completion of each such expansion, Rubicon shall, utilizing said procedures,
conduct a performance test of each plant within its then expanded Aniline
Facilities to determine the Post-Expansion Rated Capacity thereof. The
difference between the Pre-Expansion and Post-Expansion Rated Capacities of each
plant within the Aniline Facilities as so determined shall be the Expansion
Rated Capacity of such plant resulting from such expansion.

          11.5 After completion of each post-expansion performance test referred
to in paragraph 11.4, the definition of the respective percentage entitlements
of the Users in this Operating Agreement shall be amended by replacing the
percents then specified therein with percents for each User for each plant
within the Aniline Facilities derived as follows:

     (i)    multiply the Pre-Expansion Rated Capacity of each plant within the
            Aniline Facilities by each User's percentage entitlement prior to
            such expansion, then

     (ii)   multiply the Expansion Rated Capacity of each plant within the
            Aniline Facilities by each User's Expansion Percentage, then

     (iii)  as to each plant within the Aniline Facilities, add the results of
            (i) and (ii) for each User, then

     (iv)   as to each User for each plant within the Aniline Facilities, divide
            the result of (iii) for each User by the Post-Expansion Rated
            Capacity of such plant.

                                       27


The resulting percent for each User for each plant within the Aniline Facilities
shall be the amended percent for each User with respect to each such plant in
the definition of percentage entitlement in this Operating Agreement.

          11.6 If only one User ("the first User") participates in such an
expansion, the first User shall, if requested by the other User ("the second
User"), during any period production of a product by a plant within the Aniline
Facilities is reduced or eliminated by reason of making such expansion prior to
Completion of such expansion, furnish to the second User, out of the first
User's entitlement to such product available from Rubicon or otherwise, a
quantity of such product equal to the difference between

               (i)  the second User's percentage entitlement to the Pre-
          Expansion Rated Capacity of such plant and

               (ii) the quantity of such product actually available to the
          second User from Rubicon while such reduction or elimination
          continues.

Such quantity of such product shall be so furnished at no cost to the second
User beyond its cost for such product from Rubicon in accordance with this
Operating Agreement.  If any of such quantity of such product is furnished to
the second User from the first User's entitlement thereto from Rubicon, it shall
be treated by Rubicon as having been ordered by and allocated to the second User
for all purposes under this Operating Agreement, except that such quantity of
such product shall be deemed to have been allocated to the first User for the
purposes of subparagraph 5.6(d) of this Operating Agreement.  If any of such
quantity of such product is furnished to the second User by the first User from
outside Rubicon, the second User shall pay the first User therefor only an
amount equal to the variable cost for an equal quantity of such product charged
by Rubicon in accordance with this Operating Agreement immediately prior to the
reduction of production caused by such expansion, plus, if benzene is included
in such product, an amount equal to the second User's then current cost of
benzene for the amount of benzene included in such product.

          11.7 Upon Completion of the first such expansion, subparagraph 5.6(c)
of this Operating Agreement shall be amended in its entirety to read as follows:

                                       28


          "(c) Following Completion of the first expansion referred to in
          paragraph 11.4 of this Operating Agreement, and each expansion
          thereafter, except as otherwise provided in subparagraph (d) below and
          in the second paragraph of the preamble to this Section 5, the
          pre-operational costs, the start-up costs, the constant costs and the
          capital based costs incurred by Rubicon with respect to each plant
          within the Aniline Facilities shall be allocated between and paid by
          the Users as set forth below.

                  (1) The capital based costs incurred by Rubicon with respect
               to the fixed capital for each pre-expanded plant, or, in the
               event of any expansions subsequent to the first such expansion,
               with respect to the fixed capital for each previous expansion
               thereof, within the Aniline Facilities shall be allocated between
               and paid by the Users in the same proportions as before each such
               expansion.

                  (2) The capital based costs incurred by Rubicon with respect
               to the fixed capital for each such expansion of each plant within
               the Aniline Facilities and the pre-operational costs incurred by
               Rubicon with respect to each such expansion shall be allocated
               between and paid by the Users in proportion to their respective
               Expansion Percentages with respect to each such expansion of each
               such plant.

                  (3) The start-up costs incurred by Rubicon with respect to
               each such expansion of each plant within the Aniline Facilities
               shall be allocated between and paid by the Users in proportion to
               their respective post-expansion percentage entitlements to
               product from such plant.

                  (4) The capital based costs incurred by Rubicon with respect
               to fixed capital for assets acquired by Rubicon to maintain and
               operate each plant within the Aniline Facilities after Completion
               of each such expansion, but prior to any subsequent expansion,
               shall be allocated between and paid by the Users in proportion to
               their respective post-expansion percentage entitlements to
               product from such plant.

                                       29


                  (5) The constant costs incurred by Rubicon with respect to
               each plant within the Aniline Facilities after Completion of each
               such expansion shall be allocated between and paid by the Users
               in proportion to their respective post-expansion percentage
               entitlements to product from such plant."

          11.8 Upon Completion of the first such expansion, subparagraph 5.6(d)
of this Operating Agreement shall be amended by adding the following sentence.

          "Following the first expansion referred to in paragraph 11.4 of this
          Operating Agreement, and each expansion thereafter, the additional
          capital based costs referred to in the first sentence of this
          subparagraph 5.6(d) to be paid by the first User shall be based upon
          the other User's ("the second User's") average year-to-date capital
          based costs with respect to the production of such product, which, for
          this purpose, shall be determined by dividing the aggregate year-to-
          date capital based costs allocated to the second User with respect to
          such product by the number of pounds of its year-to-date entitlement
          to such product, such year-to-date entitlement to such product to be
          determined by multiplying the second User's percentage entitlement to
          such product times the Rated Capacity for such product pro-rated for
          the year-to-date period."

     12.  Expansion of Capacity to Produce DPA
          ------------------------------------

          12.1 If at any time and from time to time Uniroyal desires that
Rubicon expand its then existing capacity to produce DPA, it shall so notify
Rubicon, and, provided that Uniroyal furnishes all of the financing for the
fixed capital for such expansion in the manner and on the terms set forth in the
Financing Agreement, Rubicon shall proceed with the design and construction of
such expansion, using such process as is then available, or is made available by
Uniroyal, to Rubicon and such contractor or contractors as shall be designated
by Uniroyal, which process and contractor or contractors must be reasonably
acceptable to Rubicon's Board of Directors, acceptability of a process being
unrelated in this instance to considerations of cost but related to such
considerations as environmental requirements and plant safety.

                                       30


     13.  Expansion of or Addition to Off-sites
          -------------------------------------

          13.1 In the event the capacity to produce any product or dispose of
waste is expanded by Rubicon or RCI and such expansion requires the addition or
expansion of one or more Off-sites, or if Rubicon's Board of Directors decides
to add or expand an Off-site for any other reason, Rubicon shall proceed with
the design and construction of such Off-site addition or expansion using such
design and such contractor or contractors as shall be determined by Rubicon's
Board of Directors.

          13.2 The allocation of the fixed capital responsibility for each such
Off-site addition or expansion shall be determined at the time it is authorized
by Rubicon's Board of Directors on the bases provided in this Operating
Agreement. The appropriation request covering each Off-site addition or
expansion which is approved by Rubicon's Board of Directors shall identify the
purpose for its installation, including which plant or plants have, directly or
indirectly, the need for such addition or expansion at that time and, if two or
more plants have such need, the best engineering estimates at that time of the
relative proportions of such needs between or among such plants. For purposes of
making the allocations of responsibility for the fixed capital for each such
addition or expansion in accordance with Exhibit A, the need or needs as so
determined shall be the expected use (projected in good faith as and to the
extent reasonably able to be anticipated at that time and acceptable to
Rubicon's Board of Directors), directly or indirectly, of such addition or
expansion. Each User shall furnish the financing for the fixed capital for which
it is so allocated responsibility in the manner and on the terms set forth in
the Financing Agreement.

     14.  Certain Additional Off-sites
          ----------------------------

          14.1 If Uniroyal or another supplier shall cease to be obligated to
furnish a substance, utility or service and other arrangements for the supply of
such substance, utility or service satisfactory to both Users are not made, and
such substance, utility or service is one which could be produced or provided by
Rubicon, Rubicon shall proceed with the design and construction of the
capability to produce or provide such substance, utility or service using such
design and such contractor or contractors as shall be determined by Rubicon's
Board of Directors.  The facilities to produce each such substance, utility or
service shall be considered for all purposes of this Operating Agreement to be
an additional Off-site and, unless paragraph 14.2 applies, the provisions of
Section 13 shall apply thereto.

                                       31


          14.2 If for any reason either User (the "first User") is,
notwithstanding the provisions of paragraph 14.1, unwilling or unable to
participate in the actions contemplated therein with respect to such an
additional Off-site, the other User (the "second User") may nevertheless cause
Rubicon to proceed with the design and construction of such an Off-site,
furnishing all of the financing for the fixed capital therefor in the manner and
on the terms set forth in the Financing Agreement. In such event Rubicon shall
allocate all of the responsibility for the fixed capital and all of the
operating costs of such Off-site to the second User and Rubicon shall not use
any substance, utility or service derived from such Off-site with respect to any
conversion services for the first User, or, if the second User is Uniroyal,
services for RCI.

     15.  Expansion of Waste Disposal Plant or Different Method for the
          Disposition or treatment of Waste
          -------------------------------------------------------------

          15.1 If at any time either User proposes that Rubicon install an
expansion of the waste disposal plant, other than expansion of ancillary
facilities as contemplated in paragraph 8.4, or that Rubicon install a method or
process for disposing or treating of waste different from that of any part of
the method used in the waste disposal plant (i.e., deep well injection after
accumulation, neutralization and sand filtration), such a proposal shall
constitute a proposal for the construction of a new plant.  The User proposing
such installation (the "first User") shall so notify the other User (the "second
User") in writing, which notification shall state in detail the method or
process to be used, the cost and timing of the installation and the intended
capacity for waste disposal, as well as any other information the second User
may reasonably request.  The Users shall then consult together to consider this
proposal.  Within 90 days following its receipt of such notification and all
such information, the second User shall elect in writing whether it desires to
participate in such proposed plant, specifying, if it wishes to participate, the
capacity it desires. Failure by the second User to make any election within said
period shall be deemed an election by it not to participate in such plant.  If
both Users desire to participate in such plant, the Design Capacity of such
plant shall be the combination of the capacities desired by both Users.

          15.2 Upon completion of said notification, information, consultation
and election procedures, and provided that the User or Users participating in
such plant furnish all of the financing for the fixed capital for such plant in
the manner and on the terms set forth in the Financing Agreement, Rubicon shall
proceed with the design and construction of such plant, using such process as is

                                       32


specified by the User or Users participating in such plant and such contractor
or contractors as shall be designated by the participating User or Users, which
process and contractor or contractors must be reasonably acceptable to Rubicon's
Board of Directors.  The Users' respective responsibilities for the fixed
capital for such plant and for the financing thereof shall be in the respective
percentages of their entitlement to the use of such plant.

          15.3 Prior to the Completion of such plant this Operating Agreement
shall be amended by the addition of (i) appropriate new definitions of such
plant and percentage entitlement to the use thereof and (ii) appropriate new or
amended Sections covering the operation and the allocation and payment of the
operating costs of such plant corresponding to those Sections hereof applicable
to the waste disposal plant.  Exhibit A hereto shall also be amended by the
addition of appropriate provisions corresponding to those provisions applicable
to the waste disposal plant.

     16.  Sales of Nitric Acid and Tolling of Ammonia to Nitric Acid
          ----------------------------------------------------------

          16.1 To the extent either or both Users may, at any time and from time
to time, designate a portion of their respective entitlements to nitric acid as
available for sale, Rubicon shall, to the extent it is not already committed to
another supplier, purchase such nitric acid for its requirements to produce DNT
for RCI, and Rubicon shall use its best efforts to sell such nitric acid not so
purchased,

               (i)  from the aggregate quantity of nitric acid so designated by
          the Users in proportion to each User's percentage entitlement to
          nitric acid until a User's designated quantity of nitric acid has been
          depleted, and then

               (ii) from the remaining designated quantity of nitric acid of the
          other User, if any.

To the extent that the Users do not make nitric acid available for Rubicon's
requirements for RCI, Rubicon shall purchase such requirements elsewhere.

          16.2 All sales of a User's nitric acid (other than sales to Rubicon
for its requirements for RCI), if any, shall be made by Rubicon as undisclosed
agent for such User and Rubicon shall pay, or credit, the proceeds from sales of
such User's nitric acid to such User, but Rubicon shall invoice and receive
payment in its own

                                       33


name. Rubicon shall be reimbursed by each User for Rubicon's selling expenses
incurred on behalf of such User. Rubicon shall pay or credit to each User from
which it purchases nitric acid the then current market price of nitric acid,
f.o.b. supplier.

          16.3 To the extent either or both Users may, at any time and from time
to time, designate a portion of their respective percentage entitlements to the
productive capacity of the nitric acid plant as available for tolling nitric
acid for outside customers (i.e. producing nitric acid for such customers from
ammonia supplied by the customers and charging such customers a tolling fee),
Rubicon shall use its best efforts to arrange tolling for such customers, and
Rubicon shall perform such tolling

               (i)  by utilizing the aggregate productive capacity so designated
          by the Users in proportion to each User's percentage entitlement to
          the productive capacity of the nitric acid plant, until the designated
          portion of a User's percentage entitlement to productive capacity has
          been fully utilized, and then

               (ii) by utilizing the remaining designated portion of the other
          User's percentage entitlement to productive capacity, if any.

          16.4 All tolling of nitric acid utilizing a User's percentage
entitlement to the productive capacity of the nitric acid plant, if any, shall
be carried out by Rubicon as undisclosed agent for such User and Rubicon shall
pay, or credit, the proceeds to such User, but Rubicon shall invoice and receive
payment of the tolling fee in its own name. Rubicon shall be reimbursed by each
User for Rubicon's expenses incurred on behalf of such User to sell and provide
this service.

     17.  Capital and Operating Cost Responsibility and Allocation
          --------------------------------------------------------

          17.1 The capitalized expenditures made by Rubicon to acquire land, to
design and construct buildings, to acquire and install machinery and equipment
and to acquire furniture, fixtures and transportation, office and other
equipment are called fixed capital and certain costs related thereto are called
capital based costs, all as defined in this Operating Agreement.  The
responsibility for fixed and working capital and the responsibility for capital
based and other costs, respectively, shall be allocated within Rubicon and then,
for fixed and working capital responsibility, to the Users (including RCI's
allocation in ICI-AM's share) and, for capital based and

                                       34


other costs, to the Users and RCI, in accordance with the terms and conditions
of this Operating Agreement. The purpose of such allocations is to determine the
respective obligations (i) of the Users to finance Rubicon's fixed and working
capital and (ii) of the Users and RCI to reimburse Rubicon for its costs with
respect to conversion services for the production of aniline for the Users and
DPA for Uniroyal and to operate the RCI plants and to provide substances,
utilities and services for RCI. The responsibility for the portions of the fixed
and working capital for the waste disposal plant and the Off-sites which are
allocated to the RCI plants shall be allocated to ICI-AM. The portions of the
capital based costs incurred by Rubicon with respect to the waste disposal plant
and the Off-sites which are allocated to the RCI plants shall be allocated to
RCI. Except with respect to RCI as aforesaid and as provided in Section 5 of
this Operating Agreement, capital based costs shall be allocated correspondingly
with fixed capital responsibility. Other operating costs shall be allocated as
provided in this Operating Agreement.

          17.2 (a) The responsibility for the fixed capital for each of
     Rubicon's assets and the corresponding responsibility for the capital based
     costs associated with each of Rubicon's assets are determined and allocated
     to the Users at the time of acquisition as provided in this Operating
     Agreement. Such responsibilities shall not be reallocated unless by
     agreement between the affected parties.

               (b) In the event either User or RCI or, in the case of the
     Aniline Facilities, either User or both Users (hereinafter in this
     paragraph 17.2 individually or collectively called "the Reducing Party")
     proposes a substantial reduction in operations for it for at least one year
     or a permanent shutdown of a plant operated by Rubicon for it, or, in the
     case of RCI, it exercises the right provided in paragraph 9.3, the parties
     shall promptly determine if and to what extent Rubicon may adjust its
     operations so as to reduce its constant costs without adversely affecting
     Rubicon's safety or efficiency.  Except as to those constant costs referred
     to in (c) below, the remaining constant costs shall thereafter be allocated
     to the remaining plants and Off-sites as provided in this Operating
     Agreement.

               (c) All net additional or continuing costs which are incurred as
     a result of, or continue notwithstanding, such reduction or shutdown, e.g.
     take or pay penalties under supply contracts, utility demand charges,
     pension and other benefit costs, and severance pay for employees terminated
     by reason of such permanent reduction or shutdown, but excluding foregone

                                       35


     volume or quantity discounts, shall be allocated to the permanently reduced
     or shutdown plant and paid by the Reducing Party (and in the case of both
     Users permanently reducing or shutting down the Aniline Facilities,
     allocated between and paid by them in their respective percentage
     entitlements at the time of such permanent reduction or shutdown).  "Net
     additional or continuing costs" are the aggregate balance of such costs
     over those costs not otherwise absorbed by the expansion or addition of
     other operations at the time of or subsequent to such reduction or
     shutdown.

          17.3 Unless otherwise agreed between ICI-AM and Uniroyal, all property
which will qualify for investment tax credit under Section 38 of the Internal
Revenue Code which Rubicon acquires for inclusion in the Aniline Facilities, the
DPA plant, the waste disposal plant, the Off-sites and any additional plants
shall become subject to the Lease as provided therein.

     18.  Term of this Operating Agreement
          --------------------------------

          18.1 This Operating Agreement shall remain in effect until terminated
as herein provided.  Termination of this Operating Agreement may be effected
only by all parties agreeing thereto in writing, which agreement to terminate
may not be rescinded by any party without the written consent of the other
parties.

     19.  Allocations by Rubicon Under Certain Circumstances
          --------------------------------------------------

          19.1 In the event Rubicon, for any reason, is unable to provide
sufficient utility services, waste disposal plant use, or Off-site use to
operate all of its and RCI's plants at each of such plants' scheduled production
level, Rubicon shall allocate its available utility services, waste disposal
capability and Off-site use on a fair and reasonable basis among all those
plants then requiring such utility services, waste disposal or Off-sites, having
regard first to (i) the obligations undertaken by the respective parties to
Rubicon and by Rubicon to the respective parties with respect to those plants
and (ii) the technical necessities and feasibilities of operating each of such
plants at reduced levels or during alternating periods, and, secondarily, to the
current business needs of the respective parties entitled to the products of
such plants.  The purpose of this Section 19 is to record the understanding of
the parties to this Operating Agreement that, under circumstances of
uncontrollable reductions of one or more of those services and uses referred to
in this Section 19, Rubicon, while attempting to accommodate the desires and
needs of all parties as fairly as possible,

                                       36


will not follow any purely mechanical procedure or priority schedule in
determining how to allocate available services and uses.

     20.  General Provisions
          ------------------

          20.1 Rubicon shall operate the Aniline Facilities as provided in
Section 5, the DPA plant as provided in Section 6 and the RCI plants as provided
in Section 9. All of the products and by-products resulting from Rubicon's
operation of the Aniline Facilities and the DPA plant which are not utilized by
Rubicon in the operation of such facilities or which are not discharged by
Rubicon as waste shall be furnished by Rubicon to or on behalf of the Users in
accordance with this Operating Agreement; and, except to the extent paid as rent
under the Lease, all of the pre-operational, start-up, capital based, constant
and variable costs incurred by Rubicon with respect to its facilities shall be
allocated to, and paid by, the Users and RCI in accordance with this Operating
Agreement.  So long as Rubicon is operating the RCI plants, it shall operate
them, in accordance with this Operating Agreement, exclusively for, and as
directed by, RCI; and RCI shall pay all of the costs incurred by Rubicon with
respect to such operation.

          20.2 Each of the Users and RCI, acting for itself, shall make such
disposition as it deems appropriate of the products and by-products resulting
from the conversion services performed by Rubicon for such User and from the
operation of the RCI plants by Rubicon for RCI.

          20.3 Except as provided in paragraph 2.3 and Section 16, title to
benzene furnished by the Users and material-in-process, products and by-products
of the Aniline Facilities and the DPA plant in the possession of Rubicon at any
time shall be vested in the Users in the respective proportions in which each
User's interest therein shall appear at such time.  Title to aniline furnished
by RCI and material-in-process, products and by-products of the RCI plants under
Rubicon's control at any time shall be vested in RCI.

          20.4 If Rubicon under this Operating Agreement or under the Lease
charges an amount to one User ("the first User") or RCI, and if the first User
or RCI fails, upon written demand by Rubicon, either (i) to pay said amount to
Rubicon or (ii) to advance said amount to Rubicon under protest and without
prejudice to any claim by the first User or RCI that such amount was improperly
charged to the first User or RCI, then,

                                       37


          (a) the right which the first User or RCI would otherwise have to
     order and receive products, services, utilities and use of facilities from
     Rubicon shall be suspended so long as said failure by the first User or RCI
     continues, and

          (b) the other User ("the second User") shall have, in the event of
     such failure by the first User only, in addition to all of the second
     User's other rights, the right, if the second User so elects, to pay all or
     any part of said amount to Rubicon and forthwith to recover the same from
     the first User or from Rubicon or in part from the first User and in part
     from Rubicon, it being understood that Rubicon and the first User shall be
     liable in solido to the second User, or, in the alternative, the second
     User may waive such recovery and may, while making said payments, and to
     the extent thereof, order Rubicon to perform conversion services hereunder
     for the second User.

          20.5 Each User and RCI hereby agrees with each of the others that it
will comply with its obligations to Rubicon under this Operating Agreement and
each of the other agreements entered into by it with Rubicon as contemplated by
this Operating Agreement.

          20.6 The Users shall have the right from time to time to examine
jointly, or cause to be examined jointly, the books and records of Rubicon.  If
either User does not wish to participate in such examination, the other User
shall have the right to conduct such examination alone.  The Users shall also
have the right to require an annual audit of Rubicon's books and records by
independent certified public accountants.  To the extent that the Users shall
agree upon the scope of such audit, the cost thereof shall be borne by the Users
equally; but, to the extent that one User shall require an audit greater in
scope than that agreed to by the other User, the User requiring the greater
scope of audit shall bear the extra cost. thereof.

          20.7 This Operating Agreement shall be binding upon and shall enure to
the benefit of the parties, their successors and permitted assigns.  This
Operating Agreement may not be assigned by Rubicon or RCI.  It shall be assigned
by a User in and only in conjunction with a transfer of all of the shares of
Rubicon held by ICI American Holdings Inc. and Uniroyal, respectively, in
accordance with the Shareholders Agreement, dated January 11, 1982, among
Imperial Chemical Industries PLC, ICI American Holdings Inc. and Uniroyal, or
upon the written approval of the other User.

                                       38


          20.8  Any delay or failure by any party hereto in performance
hereunder shall be excused if and to the extent that such delay or failure shall
be related to occurrences beyond such party's control, including, but not
limited to, decrees or restraints of government, acts of God, strikes or other
labor disturbances, war, sabotage, or any other cause or causes, whether similar
or dissimilar to those already specified, which cannot be controlled by such
party. Such performance shall be so excused during the continuance of the
inability of the party to perform so caused, but for no longer period, and the
cause thereof shall be remedied as far as possible with all reasonable dispatch.

          20.9  Failure of any party to insist, in any one or more instances,
upon a strict performance of any of the terms of this Operating Agreement or the
waiver by any party of any term of right or any default of any other party
hereunder will not be deemed or construed as a waiver or a relinquishment for
the future of any such term, right or default.

          20.10 All questions relating to the validity, interpretation or
performance of this Operating Agreement shall be determined in accordance with
the law of the State of Louisiana.

          20.11 This Operating Agreement may be amended from time to time only

specifically authorized by its Board of Directors and duly executed by each of
the other parties.

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


I.   OBJECTIVE
     ---------

     The objective of this Exhibit is to set forth the principles of capital
     responsibility and cost allocation required by the Operating Agreement.

II.  DEFINITIONS
     -----------

     All terms which are defined in the Operating Agreement or any other Exhibit
     thereto are used in this Exhibit as so defined, including, or in addition
     to, the following definitions.

     A.   Fixed Capital
          -------------

          Fixed capital consists of capitalized expenditures to acquire land, to
          design and construct buildings, to acquire and install machinery and
          equipment, and to acquire furniture, fixtures, transportation, office
          and other equipment, and construction in process.  Net fixed capital
          shall be computed by deducting accumulated depreciation from fixed
          capital.

     B.   Working Capital
          ---------------

          Working capital consists of funds required for expenditures other than
          for fixed capital, including, but not limited to, spare parts,
          purchased materials, supplies, taxes and prepaid and accrued items.

     C.   Capital Based Costs
          -------------------

          Capital based costs consist of book depreciation as agreed to by the
          parties from time to time to zero net book value and interest on
          indebtedness for fixed capital.  Gains and losses from the disposition
          of assets financed by fixed capital shall be credited or charged to
          the plants correspondingly with the responsibility for the fixed
          capital of each such asset.

     D.   Constant Costs
          --------------

          Constant costs consist of costs other than capital based costs and
          variable costs, including, but not limited to, interest on working


          capital loans; salaries; payroll overheads (such as pension costs,
          F.I.C.A., medical benefits, vacations, holidays, etc.); all charges
          for utilities (except variable charges for steam); costs of operating
          supplies; costs of outside services and contractors; travel and
          entertaining; taxes (other than income taxes); and insurance.

     E.   Fixed Costs
          -----------

          Fixed costs consist of capital based costs plus constant costs.

     F.   Variable Costs
          --------------

          Variable costs consist of those costs which vary directly with the
          amount of production, including, but not limited to, costs of
          purchased raw materials and catalysts; variable charges for steam;
          costs of drums; and technical assistance fees and royalties based on
          production.

     G.   Pre-Operational Costs
          ---------------------

          Pre-operational costs consist of those costs incurred after the
          decision has been made to make an expenditure for fixed capital but
          prior to the initial operation of facilities resulting from such
          expenditure, including, but not limited to, costs incurred to plan
          resource requirements, secure sources of supply, develop operating
          procedures, and recruit and train production personnel.

     H.   Start-Up Costs
          --------------

          Start-up costs consist of initial production costs, including, but not
          limited to, costs deemed to be excessive prior to achieving an
          economic or planned level of production.

                    such expenditure is made on the basis of the best
                    engineering estimates at that time as to the expected use of
                    the ancillary facilities by such plant or plants, i.e., not
                    on the basis of the aggregate overall allocation of the

     B.   Allocation of Responsibility for Working Capital to Users and RCI
          -----------------------------------------------------------------

          Responsibility for the working capital for each of Rubicon's plants
          and for that part of the working capital for each Off-site which is
          allocated to each such plant and the RCI plants shall be allocated to
          the Users, and to ICI-AM for the RCI plants, on the basis of current
          levels of activity of all such plants and the RCI plants.

IV.  ALLOCATION OF COSTS (OTHER THAN VARIABLE)
     -----------------------------------------

          disposal plant shall be reallocated to RCI.

     B.   Constant costs shall first be allocated to Rubicon's plants and the
          RCI plants as provided in Section V. The constant costs allocated to
          each of Rubicon's plants and each of the RCI plants, including that
          part of the constant costs for each Off-site which is allocated to
          each of Rubicon's plants and the RCI plants, shall (except as provided
          in Section 5 of the Operating Agreement) then be allocated to the
          Users on the basis of percentage entitlement or Expansion Percentage,
          as appropriate, for the Aniline Facilities, to Uniroyal for the DPA
          plant, to the Users on the basis of WD percentage entitlement for the

     C.   The pre-operational costs and start-up costs which are not deferred
          and capitalized shall be allocated to the Users correspondingly with
          their respective responsibilities for the fixed capital with respect
          to which such costs were incurred.  Unless the Users otherwise agree,
          all pre-operational and start-up costs shall not be deferred and
          capitalized and shall be charged immediately to the Users.

V.   BASES FOR ALLOCATING CONSTANT COSTS TO PLANTS
     ---------------------------------------------

     A.   Estimated Services Rendered
          ---------------------------

          Production Departments
          Administration Department
          Technical and Engineering Department
          Purchasing Department
          Traffic Department
          Order Processing and Billing Department
          Chemical Warehouse and Materials Handling Department

          To make the allocations under this basis, the duties of each employee
          in the above Departments shall be analyzed to determine the expected
          proportion of each employee's time to be devoted to servicing each
          plant at the current annual budgeted level of activity.  The
          proportion as so determined shall be weighted by the individual's
          annual salary and a composite weighted average for each Department
          shall be

                                       5


          calculated. This composite weighted average shall be used to allocate
          the Department's constant costs to the plants.

     B.   Actual Services Rendered
          ------------------------

          Maintenance

          The constant costs incurred to maintain and repair buildings,
          machinery and equipment shall be recorded and charged by project work
          order.

     C.   Current Annual Budgeted Level of Activity
          -----------------------------------------

          Electrical power
          Steam (other than variable costs)
          Natural Gas
          Water
          Nitrogen
          Taxes (other than income taxes)

     D.   Percentage of Gross Capital
          ---------------------------

          Fire protection
          Property Insurance (other than on inventories)
          Auxiliary facilities, including roads and parking lots, rail sidings,
          grounds and fences, administration building, maintenance building and
          vehicles.

          The constant costs incurred for these matters shall be allocated to
          each of Rubicon's plants and each of the RCI plants in the same
          proportion as the gross fixed capital allocated to each such plant
          bears to the total gross fixed capital of Rubicon and the RCI plants.

     E.   Direct Labor
          ------------

          Accounting Department
          Management Information Services Department

          Safety Department
          Janitorial Department
          Factory Management Department
          Liability Insurance

          The constant costs of the above Departments and Liability Insurance
          shall be allocated to each plant in the same proportion as the direct
          labor salaries expected to be charged to each plant at the current
          annual budgeted level of activity is to the total direct labor
          salaries expected to be charged to all plants at the current annual
          budgeted level of activity.

     F.   In the event there is a material change in the annual level of
          activity from the current annual budgeted level of activity used as
          the basis for allocating costs in this Section V., then this basis
          will be revised to reflect such change in such allocation for the
          remaining part of that year.

VI.  ALLOCATION OF VARIABLE COSTS TO USERS AND RCI
     ---------------------------------------------

     The variable costs will be charged to the Users and RCI using:

     A.   Standard Cost per unit times actual units produced.
          -------------

     B.   Variations from standard cost per unit of production
          -----------------------------

          (1   Price Variance
               --------------

               Price variance is the difference between monthly average actual
               cost per unit and standard cost per unit multiplied by the actual
               units consumed in each plant calculated and distributed to
               products on the basis of output of each product.

          (2   Usage Variance
               --------------

               Usage variance is the difference between actual usage on a year-
               to-date weighted average basis and the standard allowance
               multiplied by the standard cost calculated and distributed to
               products on the basis of output of each product.

                                       7


VII.  ALLOCATION OF TRANSPORTATION COSTS TO USERS AND RCI
      ---------------------------------------------------

      The costs of transportation incurred for deliveries of a product as
      directed by a User or RCI shall be allocated to such User or RCI.

VIII. ALLOCATION OF INCOME TAXES TO USERS
      -----------------------------------

      The cost of Rubicon's income taxes will be allocated equally to the Users.

IX.   BILLING AND PAYMENT
      -------------------

      Bills for all costs incurred in each month shall be submitted to each User
      and RCI not later than the 15th working day of the following month and
      shall be payable within 10 days from the billing date.

          production/inventory, DPA production/inventory, benzene
          inventory/consumption, reconciliation of cash advances, reconciliation
          of construction bank account, and an analysis of the variable,
          constant and capital based costs incurred with respect to each of
          Rubicon's plants and each of the RCI plants, including those for
          Off-sites and the allocation thereof.

          3.   Financing Commitments
               ---------------------

          3.1  ICI-AH and ICI-AM (in solido but acting individually from time to
time as determined between them and hereinafter collectively called "ICI") on
the one hand, and Uniroyal, on the other hand, hereby each establishes in favor
of Rubicon a Fixed Capital Financing Commitment ("F.C.F. Commitment") in such
amount which, in the aggregate from time to time, is equal to that part of
Rubicon's

                                       2


fixed capital for which it is responsible as determined in accordance with the
Operating Agreement (deeming ICI's responsibility to be the responsibilities for
fixed capital allocated to ICI-AM and RCI), minus, for each, one half of the
sum, from time to time, of Rubicon's equity, capital surplus and retained
earnings. ICI and Uniroyal, respectively, shall lend funds to Rubicon pursuant
to their respective F.C.F. Commitments upon call by Rubicon as hereinafter
provided.

          3.2  ICI and Uniroyal hereby each establishes in favor of Rubicon a
Working Capital Financing Commitment ("W.C.F. Commitment") in such amount which,
in the aggregate from time to time, is equal to that part of Rubicon's working

allocated to ICI-AM and RCI).  ICI and Uniroyal, respectively, shall lend funds
to Rubicon pursuant to their respective W.C.F. Commitments upon call by Rubicon
as hereinafter provided.

          3.3  The respective F.C.F. Commitments and W.C.F. Commitments
(hereinafter collectively referred to, for ICI or Uniroyal, as the "Commitment"
and, for both, as the "Commitments") are, as between ICI and Uniroyal, several
and not in solido, and neither ICI nor Uniroyal shall have any responsibility in
respect of the Commitment of the other.

          4.   Calls on the Commitments
               ------------------------

          4.1  Rubicon shall, from time to time as required by it, call upon ICI
and Uniroyal, respectively, to lend to it funds pursuant to their respective
Commitments and, for this purpose, shall use its best efforts to estimate the
proper allocation of each such call and all such calls cumulatively between them
in the anticipated proportions of their respective cumulative Commitments.  If
at any time and from time to time such calls, in the aggregate, have not been in
the proper proportions, Rubicon, ICI and Uniroyal shall adjust the Loans
referred to below accordingly.

          5.   Loans
               -----

          5.1  Upon the calls from Rubicon referred to in Section 4, ICI and
Uniroyal shall each make a loan ("Loan") to Rubicon in a principal amount equal
to its Commitment, adjusted from time to time as provided in paragraph 4.1.
Follow  ing the making of the first Loans, all Loans made by ICI and Uniroyal,
pursuant to calls

                                       3


on their respective Commitments, shall be added to the outstanding principal
amount of their respective Loans.

          5.2  The principal of each Loan shall be payable by Rubicon on the
15th workday of each month in an amount equal to the capital based costs, except
interest, incurred by Rubicon and allocated to ICI-AM and RCI, on the one hand,
and Uniroyal, on the other hand, respectively, in accordance with the Operating
Agreement, in the preceding month with respect to the fixed capital financed by
such Loan, plus any amount by which the respective then current W.C.F. Commit
ments are less than the principal amount of working capital included in the
Loans.

          5.3  Each Loan shall bear interest on the unpaid principal amount
thereof outstanding, payable monthly in arrears on the 15th of each month,
commencing with the first such date after making said Loans, at the rate of 9%
per annum calculated on the basis of a year of 365 (or 366) days for the actual
number of days elapsed.

          5.4  Payments of principal and interest on each Loan may be made by
Rubicon crediting the amounts thereof to the respective obligations of ICI-AM
and Uniroyal for capital based costs under the Operating Agreement or rent under
the Lease, or a combination thereof, as the case may be.

          6.   Revision of Commitments and Loans
               ---------------------------------

          6.1  If, in accordance with the Operating Agreement, there are changes
in the respective fixed or working capital responsibilities of ICI (deeming
ICI's responsibility to be the responsibilities of ICI-AM and RCI) and Uniroyal,
their respective F.C.F. Commitments and W.C.F. Commitments shall be changed
accordingly as of the date of such change. If as a result of such changes the
outstanding principal of the respective Loans is lower or higher than the
respective Commitments, ICI and Uniroyal, respectively, shall forthwith lend to
Rubicon the amount, if any, by which its Loan is too low, and Rubicon shall
forthwith pay to ICI and Uniroyal, respectively, the amount, if any, by which
its Loan is too high.

          7.   Miscellaneous
               -------------

          7.1  The amount of each F.C.F. and W.C.F. Commitment and Loan shall be
subject to audit and verification by Rubicon's independent certified public
accountants from time to time and, if and to the extent found to be incorrect,
shall be appropriately adjusted as provided herein to reflect the correct
amounts. Subject to

                                       4


such audit and verification and appropriate adjustment, if any, the principal
amount of each F.C.F. and W.C.F. Commitment and Loan shall be as determined from
Rubicon's books and records.

          7.2  Failure by any party to insist, in any one or more instances,
upon a strict performance of any of the terms of this Agreement or the waiver by
any party of any term or right or any default of any other party hereunder will
not be deemed or construed as a waiver or a relinquishment for the future of any
such term, right or default.

          7.3  This Agreement may be amended by written instrument executed on
behalf of each party hereto (except RCI which is a party hereto only for the
purpose of the assignment in paragraph 1.1) by an authorized officer thereof.

performance of this Agreement will be determined in accordance with the law of
the State of Louisiana.
