Interest shall be computed on a per annum basis of a year of 365 days or 366 days in a leap year, as the case may be. 1. Payment Terms. Principal and interest shall be due and payable as -------------- follows. To the extent that the proceeds from the sale of any of the 4,819,674 shares of the common stock of Loch Harris, Inc. ("Loch") previously received by Lender in connection with the purchase by Loch of Borrower from Lender, plus the proceeds from the sale of any spin-offs, stock dividends, cash dividends or any other payment or item of value paid in connection with such shares (all the foregoing collectively referred to as "Stock Related Property"), plus the value of any Stock Related Property remaining after such sales, exceed an amount equal to the principal, plus interest at seven percent (7%) simple interest per annum from the date hereof, plus any amount due to Lender pursuant to a Consulting Agreement, this Note shall be considered paid in full and Lender shall immediately release any lien or claim Lender has against the Property, the Borrower and Loch. In addition, if the value of the Stock Related Property, plus the proceeds received by Lender from the sale of any Stock Related Property, exceeds such an amount, Lender shall sell such Stock Related Property and pay any excess to Loch. Value for the Loch stock, as well as any other stock included in the Stock Related Property shall mean the highest mean average of the closing bid and asked price on any date prior to February 28, 2002 that such stock becomes negotiable and eligible to be sold by Lender or Lender's agents. If such value, plus the proceeds from the sale of any Stock Related Property, does not equal or exceed the remaining principal, plus accrued interest, plus accrued consulting fee by February 28, 2002, but does equal or exceed a value of at least one-half of such amount, then such amount shall be credited against the remaining principal, accrued interest and consulting fee, this Note shall be renewed for one (1) year and the interest rate shall be reduced to five percent (5%) simple interest per annum on the remaining balance. If such value, plus any proceeds received by Lender from the sale of any Stock Related Property does not equal or exceed at least one-half the amount of the remaining principal, accrued interest, plus the consulting fee, then the remaining shares of Loch stock, plus any spin-offs, split-offs, stock dividends, cash dividends or any other payment or item of value paid in connection with such shares shall be returned immediately to Loch or Loch's designee and Lender's sole recourse shall be to the Property secured by the Deed of Trust. If the real or personal property secured by the Deed of Trust/Security Agreement/Financing Statement is sold as discussed in Paragraph 13 of the Loan 1 Agreement, the collateral and Stock Related Property shall be disposed of as therein provided. Lender further agrees that when and if any of the Stock Related Property becomes negotiable, Lender shall use his best efforts to sell such shares to maximize value and sale proceeds. Lender agrees to sell such shares in such a manner that will not unreasonably disrupt the market for such shares and that from the first $450,000 in proceeds from the sale of such shares, fifty percent (50%) of such proceeds shall be promptly paid to Loch in connection with funds previously advanced to Borrower by Loch and Lender shall retain fifty percent (50%) of such proceeds which shall be credited against sums due pursuant to this Note. 2. Interest Rate.
