All Materials shall be weighed on a truckload basis for bulk Material when Purebase sends trucks off of the property. Purebase shall pay US Mine Corp Ten Dollars ($10.00) per truckload sent over the truck platform scale.

Operation of the scale shall be by a certificated weigh-master. A weight certificate and a copy thereof, shall be prepared for each and every load of the Materials sent to the weigh-master by Purebase. A duplicate of all weight certificates shall be delivered to US Mine Corp and Purebase. In the event that the scale installed pursuant to this Section 8 fails for any reasons to function properly, and repair thereof cannot be effected within a reasonable period of time, Purebase and US Mine Corp shall cooperate in good faith to weigh tonnage of the Material supplied at any public scales operated by a weigh-master available or at any other scales operated by a weigh-master until the US Mine Corp scales are repaired.

EXHIBIT A

PRICE LIST

Purebase Corporation agrees to pay the following prices:

PRICE ADJUSTMENT

The price for each Material listed in this Exhibit A and any other additional minerals or commodities mined or processed, which are not listed, which the Parties have agreed, in writing, to add subsequently as part of this Exhibit A, shall be adjusted quarterly, effective October 1^st, January 1^st, April 1^st and July 1^st of each calendar year pursuant to the process below:

Each year, the Parties shall use the Bureau of Labor Statistics, Producer Price Index for Kaolin and Ball Clay (Table 11) Industry Product Code 212324-O for the month of June from the previous year and June in the current year and calculate the differential between the indices to equate a percentage price increase or decrease from the prior year. The current Bulk Kaolin Clay Price price shall then be multiplied by the percentage price increase or decrease and added to or subtracted from the current price for both Bulk and Bagged Products. This amount shall become the new price for effective December 1^st. Except, in no event, shall the new price be less than the original price stated in this Exhibit A, unless agreed to in writing by each Party. To the extent the Bureau of Labor Statistics, Producer Price Index for Kaolin and Ball Clay (Table 11) Industry Product Code 212324-O does not include price fluctuations for fuel prices used in the mining of the Materials, US Mine Corp reserves the right to further adjust the prices quarterly based on substantiated increases in gasoline and/or diesel fuel prices.

Parties also agree that if Purebase supplies the bags the total charge will be reduced by the cost of the bags incurred by Purebase.

If Purebase provides clay product to the facility at its cost, the bagged cost will be reduced by an amount equal to the Bulk Kaolin Clay price
