ARTICLE 2 - SALE OF AERATION TECHNOLOGY AND ROYALTY INTEREST

         2.01 Inventor hereby sells, transfers, assigns and conveys to Essential
all right title and interest in and to the Aeration Technology.

         2.02 The parties shall co-operate in the development and marketing of

         2.04 Payment of Royalty: The Royalty shall be calculated on a calendar
quarter basis and paid, without set-off or counterclaim, for each quarter within
30 days of the end of such quarter. Any amounts not paid within 30 days shall
bear interest, calculated from the end of the quarter for which such payment was
due, at the prime lending rate charged by the Royal Bank of Canada to its most
credit worthy customers plus two percent (2%). To the extent that the revenue
received by Essential for the sale of the Aeration Technology or other
applications of the technology is in a form other than the lawful currency of
the United States of America, the Royalty shall be paid to Inventor in the

exchange rates (as constituted on the last day of the applicable quarter)
reasonably designated by Inventor. Essential shall be responsible for
maintaining books and records which accurately document its revenues and the
Royalty.

         2.05 Report of Aeration Technology Sales: Within 30 days following the
close of the first calendar quarter in which there are any revenues generated
from the Aeration Technology, Essential shall provide Inventor with a written
report showing the sales in such quarter and the amount of Royalty payable with
respect thereto, certified by the accountant for Essential. Thereafter, within
30 days following the close of each calendar quarter, Essential shall provide
Inventor with a written report showing the amount of sales in such quarter and
the amount of Royalty payable with respect thereto.

         2.06 Examination of Books and Records: Upon the written request of
Inventor and, except as otherwise provided below, at Inventor's expense,
Essential shall allow and make available (during reasonable times and with
reasonable advance notice so as to minimize interference with Essential's
business operations) its books and records to be examined and audited by an
independent firm of chartered accountants appointed for the purpose of
determining compliance with Royalty obligations under this Agreement. If such
audit discloses any discrepancy in the amount of Royalty paid, the appropriate
adjustment shall be made immediately thereafter. To the extent of an
overpayment, the amount due from Inventor shall be deducted from future
payments. In the event that any such examination or audit shall determine that
the Royalty actually paid for any period was less than 95% of the amount
properly payable, or was greater than the amount that should have been paid,
Essential shall pay the reasonable expenses actually incurred by Inventor in
connection therewith, in addition to all previously unpaid Royalties. Inventor
and its representatives shall not use or disclose such books and records, nor
any of the specific information contained therein, to any third parties except
as reasonably necessary if Essential is in breach of this Agreement.
