                  Shares, at an agreed upon price of $ .3975 per Sol6 Share
                  [i.e., AUS$.75 per share x .53 conversion rate], and at an
                  agreed upon re-purchase price of $3.00 per share of Common
                  Stock; (b) $554,931 of the principal amount of the Promissory
                  Note shall be deemed to be reduced due to the purchase by
                  Tyler of Common Stock from other shareholders of the Company
                  as discussed in Section 3(a) above; and (c) the remaining
