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

    	 	3	 



     


    

 


(b)

EXHIBIT
A


 


PRICE
LIST


 


Purebase
Corporation agrees to pay the following prices:


 


	Product	 	Price
	Kaolin
    Clay for Organic Agriculture	 	$145
    per US Ton for bagged product


 


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 1st, January 1st, April 1st and July 1st 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 1st. 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
