ARTICLE XI. INSPECTION, WEIGHING, SAMPLING AND ANALYSIS

Inspection and Weighing. Inspection of Buyer's Vessels' holds for cleanliness and protection and determination of weight of Product loaded aboard Buyer's Vessel, by draft survey, will be made by Capt. G.A. Chettles & Assoc., a registered independent surveyor, or such other inspector acceptable to RBT and Buyer. The cost of such surveys shall be borne equally by RBT and Buyer and shall be included in RBT's commercial invoice referred to in Article VIII.A.1. Such surveyor shall be entitled to reject any vessel

not found to be suitable for loading of Product, provided such surveyor sends to Buyer, by facsimile, the reasons for such rejection and his certification that the Buyer's Vessel as presented would not adequately protect the Product from contamination. Such rejection shall be for Buyer's account. Such surveyor shall determine the weight of Product loaded aboard Buyer's Vessel. The Product weight so determined, which includes moisture, shall, on the basis of the analyses of the Official Samples then be adjusted for the moisture content. The resulting dry weight shall be the basis on which Product is invoiced for payment.

Sampling. Each shipment of Product delivered to Buyer's Vessel at Richards Bay shall be sampled by an independent testing company, Bureau Veritas or such other independent testing laboratory acceptable to both parties. Such independent laboratory shall take and distribute representative samples (hereinafter called "Official Samples") from each shipment in accordance With the "Sampling and Sample Preparation Procedure", set forth in Exhibit "A," Procedure "SAM 78," attached hereto and made a part hereof.

The fees for services of such independent testing laboratory shall be paid for equally by RBT and Buyer and shall be included in RBT's commercial invoice referred to in Article VIII.

C.Analysis

Methods of Analysis. All analyses shall be made by the methods outlined in Exhibit "B" Procedure "SAM 004", Exhibit "C" Procedure "SAM 124", Exhibit "D" Procedure "SAM 051", Exhibit "E" Procedure "SAM 079" and Exhibit "F' Procedure "SAM 008" which are attached hereto and made a part hereof, or by such other methods as RBT shall consider appropriate provided that the results obtained from such other methods are consistent with the results which would be obtained by using the methods outlined in the above-mentioned exhibits.

Analysis by RBT. RBT shall analyze the Official Samples and the results of such analysis for each shipment shall be provided to Buyer not later than thirty (30) days following the date of such shipment.

Analysis by Buyer. Buyer may, but shall not be obligated to, analyze the Official Samples. Unless Buyer notifies RBT within [***] of receipt of an Official Sample that Buyer's analysis indicates that Product fails to meet Specifications or that the TiO2 content is more than [***] different from RBT's analysis, the results of RBT's analysis shall be final and conclusive.

Umpire Procedure. Should Buyer's analysis of the Official Sample indicate that Product does not meet Specifications or that the TiO2 content of Product is more than [***] different from RBT's analysis, Buyer may so advise RBT and RBT shall 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 at this time for this purpose that Inspectorate Griffith Limited, 2 Perry Road, Witham, Essex, CM8 3TU, U.K. shall be the initial umpire analyst. The umpire shall analyze the Official Sample in accordance with the methods outlined in the Exhibits referred to in Article XI.C.

Settlement. The umpire's analysis as to TiO2 content and that of Buyer or RBT, whichever is in closer agreement, shall be averaged as the basis for final

settlement; provided that if the umpire's analysis lies exactly halfway between Buyer's and RBT's analyses, the umpire's analysis shall be the basis for final settlement.

If such final basis for settlement results in a price adjustment in accordance with the procedure described in Article V of this Agreement, RBT shall issue a credit or debit invoice as the case may be. If an umpire's analysis is required on any Specification other than Ti02, the umpire's analysis and that of Buyer or RBT, whichever is in closer agreement, shall be averaged as the basis for final settlement; provided that if the umpire's analysis lies exactly halfway between the Buyer's and RBT'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 IX.B. of this Agreement. The cost of an umpire's analysis shall be paid by the party whose analysis varies most from the umpire's analysis unless such variations are equal and then the cost shall be borne equally by the parties.

Revision of Sampling and Analytical Procedures. The procedures set forth in the Exhibits referred to in this article are believed to be the most satisfactory ones now available. However, better procedures may become available. Each of said Exhibits may be revised from time to time, without formal amendment to this Agreement; provided that each such revision shall require the written approval of Buyer and RBT.

ARTICLE XII. ARBITRATION

Any dispute between the parties hereto arising out of or in any way connected with this Agreement, its negotiation, performance, breach, existence or validity shall, unless settled by mutual agreement or conciliation and failing settlement thereunder, be referred 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 arbitrators of which RBT shall appoint one and Buyer shall appoint another, and the two appointed arbitrators shall appoint the Chairman of the arbitral tribunal within thirty (30) 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 and all documents submitted therein shall be in English.

ARTICLE XIII. TAXES AND DUTIES

RBT will, at its own cost and expense, defend any and all suits which may be brought against Buyer on account of said infringement of such patent or patents, and RBT 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 year in which such infringement commenced.

B.	RBT's obligations pursuant to Article XIV shall be conditional upon Buyer giving prompt

notice to RBT 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.

Any delay or interference which affects RBT' s supply of Product to customers shall entitle RBT to allocate equitably any available Product among customers in its discretion. During the pendency of any Force Majeure declared by RBT, Buyer [***] for such year shall be adjusted accordingly.

Anything to the contrary hereinabove notwithstanding, if such event occurs, the obligation of RBT to sell and deliver and of Buyer to buy and to take delivery 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 Vessel at Richards Bay, by the end of the year due to such event.

Either party may terminate the Agreement if such event continues for more than one hundred and eighty (180) days.

ARTICLE XVI. DEFAULT & LIMITS OF LIABILITY

For purposes of Article XVI, a "default" shall mean any failure by either party to make any payment when due 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.

In the event of a default arising from a breach of Buyer's duty to pay for Product delivered or for the total quantity of Product to be purchased in any particular year, RBT shall have the right to seek damages for all loss or damage actually sustained as a direct result of the default. In addition, RBT 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.

ARTICLE XVII. WAIVER OF DEFAULT
