                  6.4      For the avoidance of doubt, it is hereby clarified

                           the Minimum Price.

                           For the purposes hereof the "Minimum Price" shall

                           Israeli Shekels payable shall be determined in
                           accordance with (i) with respect to sales of Israeli
                           Market Product - the representative rate of exchange

                           Israeli Shekels excluding any premiums which Seller

                           provisions hereof.

                           In the event that the representative rate of exchange
                           shall not be published by the Bank of Israel then a
                           substituting rate shall be used, which shall resemble
                           the principles reflected in the determination of the
                           representative rate of exchange.

                           whether in contract, tort or otherwise.

                  9.2      Without prejudice to the provisions of sub-articles
                           9.1 above and 9.4 below, in no event shall any claim

                           other reason whatsoever be greater than the purchase
                           price of that portion of the product in respect of

                           amount that may be claimed by Buyer in respect of
                           damages not excluded from Seller's

                           above and shall not be interpreted so as to impose an

                           otherwise pay Buyer the above amount.

                           the specified time shall constitute a waiver by Buyer
                           of all claims in respect of such Product.

                  9.4      In the event that Product shall not conform to the

                           of the parties with respect to Product therefore
                           delivered to Buyer.

                  14.1     The weight of the Product delivered hereunder shall

                           shall be for the account of Seller.

                           14.2.3   Until such time that the analysis method
                                    referred to in 14.2.5 below shall be applied
                                    (if at all), Seller's analysis results
