          Product is less than eighty-five percent (85%). 2. If the insoluble
          TiO\\2\\ content of Product exceeds two percent (2%), the price shall
          be adjusted downwards by one-one hundred seventieth (1/170th) of the
          Basic Price for each increment of one-half percent (0.5%) or part
          thereof by which the insoluble TiO\\2\\ content exceeds two percent
          (2%).

                                  ARTICLE VI.

                                  ARTICLE XI.

                  INSPECTION, WEIGHING, SAMPLING AND ANALYSIS

A.   Inspection and Weighing
     -----------------------

     1.   RBIT shall determine the weight of Product by weighing the railroad
          car, before and after loading, on RBIT's government approved,
          inspected and certified track scale. The weight so determined shall
          then be adjusted for moisture content and the resulting dry weight
          will be the final weight on which payment shall be made. The cost of
          weighing shall be for RBIT's account.

     2.   Buyer shall be entitled, at its own expense, to verify the accuracy of
          the weighing equipment referred to in paragraph XI.A.1. In the event
          such verification reveals a weight discrepancy of more than one
          percent (1%), the parties shall negotiate a mutually acceptable price
          adjustment, failing which, the matter shall be referred to
          arbitration.

B.   Sampling
     --------

                                       10


     1.   Sampling - Each shipment of Product loaded onto railcars at RBIT's
          --------
          Plant at Richards Bay shall be sampled by Bureau Veritas or such other
          independent testing laboratory as may be agreed between Buyer and
          RBIT. Such independent laboratory shall take and distribute
          representative samples consisting of a monthly composite of individual
          shipment samples (herein called "Official Sample(s)") in accordance
          with the "SATP Slag Sampling and Sample Preparation Procedure," as set
          forth in Exhibit "A" Procedure "SAM 080," attached hereto and made a
          part hereof.

     2.   Lab Fees - The fees for services of such independent testing
          --------
          laboratory shall be borne equally by RBIT and Buyer. Buyer shall pay
          RBIT for Buyer's one-half of such fees within seven (7) days after
          receipt of an invoice therefor.

C.   Analysis
     --------

     1.   Methods of Analysis - All analyses shall be made by the methods
          -------------------
          outlined in Exhibit "B" Procedure "SAM 004," Exhibit "C" Procedure
          "SAM 006," Exhibit "D" Procedure "SAM 008," Exhibit "E" Procedure
          "SAM 001," Exhibit "G" Procedure "SAM 051," which are attached hereto
          and made a part hereof.

                                       11


     2.   Analysis by RBIT - RBIT shall analyse the Official Samples and the
          ----------------
          results of such analysis shall be provided to Buyer not later than
          twenty-one (21) days following the end of the month in which the
          shipments were made.

     3.   Analysis by Buyer - Buyer may, but shall not be obligated to, analyse
          -----------------
          the Official Samples. Unless Buyer notifies RBIT, within sixty (60)
          days of receipt of an Official Sample, that Buyer's analysis indicates
          that Product fails to meet the Specifications or that the TiO//2//
          content is more than [+++++] different from RBIT's analysis, the
          results of RBIT's analysis shall be final and conclusive.

     4.   Umpire Procedure - Should Buyer's analysis of the Official Samples
          ----------------
          indicate that Product does not meet the Specifications or that the
          TiO\\2\\ content of Products is more than [+++++] different from
          RBIT's analysis, Buyer may so advise RBIT, who will then request the
          independent testing laboratory referred to above to forward for
          analysis its retained Official. Sample to such umpire analyst (being
          an independent testing laboratory) as shall be agreed to from time to
          time by the parties. The parties hereby agree that Inspectorate
          Griffith Limited, 2 Perry Road, Witham, Essex, CN8 3TU, U.K., shall be
          the initial umpire analyst.

                                       12


     5.   Settlement - The umpire's analysis as to TiO\\2\\content and that of
          ----------
          Buyer or RBIT, whichever is in closer agreement to the umpire's
          analysis, shall be averaged to establish the revised analysis for the
          shipment. If the umpire's analysis is exactly halfway between Buyer's
          and RBIT's analyses, such umpire's analysis shall then be used to
          establish the revised analysis for the shipment.

          If such revised analysis results in a price adjustment in accordance
          with the procedures described in this Agreement, RBIT shall issue a
          credit or debit invoice as the case may be. If an umpire's analysis is
          required on any Specifications other than TiO\\2\\, the umpire's
          analysis and that of Buyer or RBIT, whichever is in closer agreement
          to the umpire's analysis, shall be averaged as the basis for final
          settlement; provided, however, that if the umpire's analysis is
          exactly halfway between Buyer's and RBIT's analyses, the umpire's
          analysis shall be the basis for final settlement. If such analysis
          determines that Product does not meet each of such Specifications, the
          parties shall proceed as described in Article X of this Agreement. The
          cost of an umpire's analysis shall be paid by the party whose analysis
          varies most from umpire's analysis unless such variations are equal,
          whereupon, the cost shall be borne equally by the parties.

                                       13


D.   Revisions of Sampling and Analytical Procedures
     -----------------------------------------------

     The procedures set forth in the Exhibits referred to in this Article XI are
     believed to be the most satisfactory ones now available. In the event
     better procedures become available, each of said Exhibits may be revised
     with the written approval of Buyer and RBIT.

                                 ARTICLE XII.

                                  ARBITRATION

Any dispute between RBIT and Buyer arising out of or in any way connected with
this Agreement, its negotiation, performance, breach, existence or validity
shall, unless settled by mutual agreement, be referred first, for conciliation
and, failing settlement thereunder, for final and binding arbitration, in
London, England, under the Rules of Conciliation and Arbitration of the
International Chamber of Commerce. The arbitration shall be presided over by
three (3) arbitrators of which RBIT shall appoint one and Buyer shall appoint
another, and the two appointed arbitrators shall appoint the Chairman of the
arbitral tribunal within sixty (60) days following their appointment by the
parties hereto, failing which the Chairman shall be appointed by the
International Court of Arbitration of the International Chamber of Commerce. The
language of the arbitration shall be English.

                                 ARTICLE XIII.

                               TAXES AND DUTIES

                                       14


All taxes or duties now or hereafter imposed in connection with this Agreement
shall be for the sole account of Buyer.

                                  ARTICLE XIV.

                                    PATENTS

A.   RBIT agrees to protect and hold Buyer harmless against any and all claims
     that Product in the state or form as sold under this Agreement infringes or
     allegedly infringes any product claims of any South African patent owned by
     third parties.  RBIT will, at its own cost and expense, defend any and all
     suits which may be brought against Buyer on account of alleged infringement
     of such South African patent or patents, and RBIT shall pay any and all
     fees, costs and damages awarded in said suits; provided, however, that the
     total liability for damages under this Article XIV shall in no event exceed
     the aggregate sales price of Product sold to buyer during the previous year
     in which such alleged infringement commenced.

B.   RBIT's obligations pursuant to this Article XIV shall be conditional upon
     Buyer giving prompt notice to RBIT of any claims by third parties of any
     such alleged infringement and of all information available to Buyer in
     respect of such alleged infringement or claim.

                                  ARTICLE XV.

                                 FORCE MAJEURE

                                       15


In the event of any contingency which is beyond the reasonable control of RBIT
or Buyer, including, but not limited to (i) any strike, lockout, industrial
dispute, difference with workmen, accident, fire, explosion, earthquake, flood,
mobilization, war (whether declared or undeclared), act of any belligerent in
any such war, civil commotion, riot, rebellion, revolution or blockade, (ii) any
requirement, regulation, restriction, or other act of any Government, whether
legal or otherwise, (iii) any inability to secure or delay in securing export
licenses or import licenses, cargo space or other transportation facilities
necessary for the shipment or receipt of Product or fuel or other supplies or
material including ilmenite ore, water or electric power necessary for the
operation of the mines and plants where Product is produced or consumed, (iv)
any delay in or interruption to transportation by rail, water or other wise, (v)
any damage to or destruction of such mines or plants or any breakdown of plants
or machinery of RBIT or Buyer, or (vi) any other contingency, excluding market
conditions of any kind, which is beyond the reasonable control of RBIT or Buyer,
whether or not of the nature or character hereinbefore specifically enumerated,
which event delays or interferes with the performance of this Agreement or the
consumption of Product (an event of "Force Majeure"), then such event shall be
considered sufficient justification for delay in making shipment or delivery or
taking delivery or performance hereunder (other than the payment of money), in
whole or in part, until such event ceases to exist, and this Agreement shall be
deemed suspended

                                       16


for so long as such event delays or interferes with the performance hereof,
provided that prompt notice of any such event be given by the party affected to
the other party. Any delay or interference which affects RBIT's supply of
Product to customers shall entitle RBIT to allocate equitably any available
Product among customers in its discretion.

     Anything to the contrary herein notwithstanding, if such event of Force
Majeure occurs, the obligation of RBIT to sell and deliver and of Buyer to buy
and to take the Contracted Quantity of Product with respect to any year shall
terminate (unless otherwise agreed between the parties) at the end of the year
as to quantities of Product which have not been loaded aboard Buyer's railcar at
Richards Bay by the end of the year due to such event of Force Majeure. Nothing
contained in this Article shall require Buyer to pay for, or RBIT to make up or
compensate for, any Product not delivered due to the application of this Article
XV.

                                  ARTICLE XVI.

                         DEFAULT & LIMITS OF LIABILITY

For purposes of this Article XVI, a "default" shall mean any failure by either
party to make any payment or to perform any obligation under or pursuant to this
Agreement for any reason other than an event of Force Majeure as defined in
Article XV.

No default shall be deemed to have occurred unless the party in default shall
have first been given notice of such default and shall have failed to cure such
default

                                       17


within thirty (30) days in the event of a failure to pay and in all other events
of default, within ninety (90) days after receipt of such written notice.

In the event of a default arising from a breach of Buyer's duty to pay for
Product delivered for the total amount of the Contracted Quantity in any
particular year, RBIT shall have the right to seek damages for all loss or
damage actually sustained as a direct result of the default. In addition, RBIT
shall have the right (subject to Buyer's right to cure its default pursuant to
this Article) to terminate this Agreement forthwith by providing notice to such
effect to Buyer. Notwithstanding anything contained herein to the contrary, in
no event shall Buyer be liable for consequential, indirect or special damages as
a result of a default for failure to pay under this Agreement.

     In the event of any default by RBIT arising from a failure to deliver
Product pursuant to this Agreement, RBIT (subject to RBIT's rights to cure its
default pursuant to this Article) shall compensate Buyer for all loss or damage
actually sustained as a direct result of the failure to deliver but excluding
indirect, consequential, punitive or contingent damages of the default Buyer
may suffer therewith including, but not limited to, loss of revenue or profits
as a result of Buyer's inability to operate, or shut down of its operations,
loss of use of equipment, or cost of substitute equipment, claims of third
parties, and the like. Buyer shall not, however, be entitled to terminate its
obligations to purchase Product under this Agreement.

                                       18


                                 ARTICLE XVII.

                               WAIVER OF DEFAULT

Any failure by either party to give notice in writing to the other party of any
breach or default in any of the terms or conditions of this Agreement shall not
constitute a waiver therefor, nor shall any delay by either party in enforcing
any of its rights hereunder be deemed a waiver of such rights nor shall a waiver
by either party of any defaults of the other party be deemed a waiver of any
other or subsequent defaults.

                                ARTICLE XVIII.

                                    NOTICE
