Pursuant to Section 4 of the agreement to which this schedule is attached, the Vendor is entitled to a royalty equal to 2.0% of all Net Smelter Returns ("NSR") received by the Purchaser or any subsequent operator (the "OPERATOR") from metal production from the Claims (as described in SCHEDULE A of the agreement), free and clear of all costs of development and operations. 2. "NET SMELTER RETURNS" shall mean the actual proceeds received by the Operator from any mint, smelter, or other purchaser for the sale of ores, metals or concentrated products from the Claims and sold after deducting from such proceeds the following charges to the extent that they were not deducted from such proceeds by the purchaser in computing payment: smelting and refining charges; penalties; cost of transportation of ores, metals or concentrates from the Claims to any mint smelter or other purchaser; marketing costs; insurance on all such ores, metals or concentrates; and any export and import taxes on said ores, metals or concentrates levied in Canada or by the country into which such ore, metals or concentrates are imported, if such charges or costs are deducted from the proceeds received. 3. Payment of the NSR royalty shall be made quarterly within 90 days after the end of each fiscal quarter of the Operator and shall be accompanied by interim or annual financial statements pertaining to the operations carried out on the Claims. Within 150 days after the end of each fiscal year of the Operator in which the NSR royalty is payable, the records relating to the calculation of NSR royalty for such year shall be audited and any resulting adjustments in the payment of the NSR royalty payable shall be made forthwith. A copy of the said audit (the "ANNUAL REPORT") shall be delivered to the Vendor within 30 days of the end of such 150-day period. 4. Each annual audit shall be final and not subject to adjustment unless the Vendor delivers to the Operator written exceptions in reasonable detail within 30 days after receipt of the Annual Report. The Vendor, or its representative duly authorized in writing, shall at its expense have the right to audit the books and records of the Operator related to the NSR to determine the accuracy of the Annual Report, but shall not have access to any other books and records of the Operator. The audit shall be conducted by a chartered or certified public accountant of recognized standing (the "AUDITOR"). The Operator shall have the right to condition access to its books and records on execution of a written agreement by the Auditor that all information will be held in confidence and used solely for purposes of audit and resolution of any disputes related to the NSR royalty. A copy of the Auditor's report shall be delivered to the Operator and the amount, which should have been paid according to the Auditor's report, shall be paid forthwith, one party to the other. In the event that the said discrepancy is to the detriment of the Vendor and exceeds 5.0% of the amount actually paid by the Operator, then the Operator shall pay the entire cost of the audit. 5. In the event smelting or refining are carried out in facilities owned or controlled in whole or in part by the Operator, charges, costs and penalties with respect to such operations, excluding transportation, shall mean reasonable charges, costs and penalties for such operations but not in excess of the amounts that the Operator would have incurred if such operations were carried out at facilities not owned or controlled by the Operator then offering comparable custom services. 6. The Vendor shall at its election have the right to take its NSR royalty in kind as it may pertain to precious metals defined as gold and platinum group elements in whole or in part. SCHEDULE C - GROSS OVERRIDINGF RECEIPTS ROYALTY 1. Pursuant to Section 4 of the agreement to which this schedule is attached, the Vendor is entitled to a royalty equal to 2.0% of all Gross Overriding Receipts ("GOR") from the average appraised value of all diamonds (the "DIAMONDS") recovered, sorted and graded by the Purchaser or any other operator (the "OPERATOR") from the Claims (as described in Schedule A of the agreement), free and clear of all costs of development and operations. 2. The expression "AVERAGE APPRAISED VALUE" shall mean the average of the valuations in Canadian dollars of the Diamonds determined by two independent graders, one appointed by the Operator and one appointed by the Vendor. Such independent graders shall be duly qualified and accredited, and shall sort, grade and value the Diamonds in accordance with industry standards, having regard to, but without limiting the generality of the foregoing, the commercial demand for the Diamonds. Each independent valuator shall value each particular classification of the Diamonds in accordance with the industry price books, standards and formulas. The parties acknowledge that the intention is that the GOR royalty be paid to the Vendor on this basis, regardless of the price or proceeds actually received by the Operator for or in connection with the Diamonds or the manner in which a sale of the Diamonds to a third party is made, and without deduction. 3. Payment of the GOR royalty shall be calculated and made quarterly within 90 days after the end of each fiscal quarter of the Operator, based on all Diamonds recovered from the Claims that were graded in such quarter. 4.
