(hereinafter referred to as "Buyer") and ELECTROPURE, INC., a California corporation (hereinafter referred to as "Electropure" or the "Company").

        1.    PURCHASE AND SALE OF SHARES

        (a)  Effective on the date hereof, the Company hereby sells to Buyer and Buyer hereby purchases Two Hundred Twenty Seven Thousand Two Hundred Seventy Three (227,273) Shares of Electropure, Inc. Common Stock (the "Shares") with an aggregate value equal to Fifty Thousand Dollars ($50,000).

        (b)  The Shares shall have the rights, preferences, privileges, restrictions and other terms set forth in the By-laws of the Company.

        2.    REPRESENTATIONS AND WARRANTIES OF BUYER    Buyer represents and warrants to the Company:

        (a)  The Shares are being acquired by Buyer for investment for an indefinite period, for Buyer's own account, not as a nominee or agent, and not with a view to the sale or distribution of any part thereof, and the Buyer has no present intention of selling, granting participations in, or otherwise distributing the same except as may be permitted by the Securities Act of 1933, as amended (the "Act").

        (b)  Buyer does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer, or grant participation to such person or to any third person, with respect to the Shares.

        (c)  That Buyer understands that the Shares have not been registered under the Securities Act of 1933, as amended (the "Act"), in reliance upon the exemptions from the registration provisions of the Act contained in Section 4 (2) thereof, and any continued reliance on such exemption is predicated on the representations of the Buyer set forth herein.

        (d)  Buyer understands that the Shares must be held indefinitely unless the sale or other transfer thereof is subsequently registered under the Act, as amended, or an exemption from such registration is available. Buyer further understands that the Company is under no obligation to register the Securities on its behalf or to assist him in complying with any exemption from registration except as otherwise provided herein.

        (e)  Buyer (i) has adequate means of providing for his current needs and possible contingencies, (ii) has no need for liquidity in this investment, (iii) is able to bear the substantial economic risks of an investment in the Shares for an indefinite period, (iv) at the present time, can afford a complete loss of such investment, and (v) does not have an overall commitment to investments which are not readily marketable that is disproportionate to Buyer's net worth, and Buyer's investment in the Shares will not cause such overall commitment to become excessive.

        (f)    Buyer is an "accredited investor" (as defined in Regulation D promulgated under the Act) and the undersigned's total investment in the Shares does not exceed 10% of the Buyer's net worth.

        (g)  Buyer recognizes that the Company has had only limited revenues to date and that the Shares as an investment involve significant risks.

The Company and Buyer acknowledges that the Company has no obligation to supply the information required for sales under Rule 144.

        (k)  The Purchase Price to be paid by Buyer to Company for the Shares has been determined by Buyer as fair and appropriate based solely upon Buyer's independent investigation and due diligence of the Company, and neither Buyer nor the Company nor any of their agents, including, without limitation, any of their officers, directors, employees, accountants and attorneys, has made any representations or warranties whatsoever in connection with the sale of the Shares by the Company to Buyer.
