Attention:  Mr. Richard Bullock

6 February 2001

Subject:  In the Matter of the Bankruptcies of
          Kafus Industries Ltd.
          Cameron Strategic Planning Ltd.
          Purchase of common shares and other assets of Hyaton Organics Inc.
          ("Hyaton") by Berkeley Investments Inc. (the "Purchaser") from the
          estates of Kafus Industries Ltd. and Cameron Strategic Planning Ltd.
          (together the "Companies") by the Companies' trustee in bankruptcy
          PricewaterhouseCoopers Inc. (the "Vendor")

Dear Sirs:

The undersigned, PricewaterhouseCoopers Inc. as trustee in bankruptcy of the
Companies, and not in its personal capacity, confirms the agreement to sell to
the Purchaser the following:

     (a)  all of the shares the Vendor holds in Hyaton being 20,000,000 common
          shares (the "Hyaton Shares"); and

     (b)  all of the interests the Vendor may have, including accounts
          receivable or shareholders' loans, in Hyaton and Camden Agro-
          Systems, Inc. (the "Non-share Interests").  The Non-share Interests
          have been outlined in the attached Schedule A.  The information in
          Schedule A is complete to the best of the Vendor's knowledge, and
          has been prepared from the Companies' financial data without audit
          or verification by the Vendor.

          (the Hyaton Shares and the Non-share Interests are referred to
          collectively as the "Assets")

on the following terms and conditions:

1.   Subject to the terms and conditions of this Agreement, the Vendor agrees
     to sell to the Purchaser and the Purchaser agrees to purchase from the
     Vendor, on the Closing Date, the Assets in consideration of the payment
     of the sum of $50,000 (the "Purchase Price").

2.   On the Closing Date, the Purchaser will have paid the Purchase Price of
     $50,000 to the Vendor by bank draft, certified cheque or wire transfer.
     The Purchase Price shall be allocated $40,000 to the Hyaton Shares and
     $10,000 to the Non-share Interests.

3.   Richard Bullock, a director of the Purchaser, resigned as an Inspector of
     the estate of the bankrupt Kafus Industries Ltd. effective January 24,
     2001.  Based upon Richard Bullock's resignation, no Court Order/approval
     has been obtained with respect to the sale of the Assets to the
     Purchaser.  The Purchaser will bear the risk of any Court setting aside
     the sale of the Assets to the Purchaser.  The Purchaser agrees to bear
     any costs incurred by the Purchaser, the Companies, the estates of the
     Companies or the Vendor associated with obtaining a Court Order/approval
     in the future or other matters which arise with the Courts with respect
     to this agreement.

4.   The Vendor provides no representation or warranty with respect to the
     Assets, except as expressly set out in this paragraph, and the Assets are
     purchased on an "as is where is" basis.  Without limiting the generality
     of the foregoing, the Purchaser acknowledges that the Hyaton Shares may
     be subject to restrictions on resale under United States federal and
     state securities legislation.  The Vendor warrants and represents that:

     (a)  the Vendor is the trustee in bankruptcy of the Companies;

     (b)  subject to the matters set out in paragraph 3 above, the Vendor has
          the right to transfer the interest of the Companies, if any, in the
          Assets; and

     (c)  the Vendor is a resident of Canada for the purposes of the Income
          Tax Act (Canada).

5.   The Vendor's obligation to carry out the terms of this agreement and to
     complete the purchase referred to in paragraph 1 is subject to the
     following condition that on or before the Closing Date the Vendor shall
     have received evidence satisfactory to it that:

     (a)  Berkeley Investments Inc. does not have any claims, rights or causes
          of action against the Companies or their estates with respect to the
          Assets; and

     (b)  neither Hyaton nor Camden Agro-Systems, Inc. has any claims, rights
          or causes of action against the Companies or their estates.

6.   The Purchaser's obligation to carry out the terms of this agreement and
     to complete the purchase referred to in paragraph 1 is subject to the
     condition that on or before the Closing Date, the Vendor will have
     delivered to the Purchaser:

     (a)  the share certificates representing the Hyaton Shares duly endorsed
          for transfer to the Purchaser along with any documentation necessary
          to reflect such transfer, such as a corporate resolution of the
          Vendor and a medallion signature guarantee; and,

     (b)  a Bill of Sale representing the transfer of the balance of the
          Assets to the Purchaser.

7.   The Vendor will transfer the corporate records of Hyaton and Camden Agro-
     Systems, Inc. in its possession that it is aware of, as indicated by the
     Purchaser.

8.   Time shall be of the essence of this agreement.

9.   This agreement shall enure to the benefit of and be binding upon the
     Vendor and its successors and assigns, and upon the Purchaser and its
     heirs, executors, successors and assigns.

10.  Any notice to be given under this Agreement shall be duly and properly
     given if delivered or mailed by prepaid registered post or by facsimile
     addressed as follows (or such other address as a party may advise in
     writing) and any such notice shall be deemed to be received on the day of
     delivery, if delivered or sent by facsimile, and 7 days after the day of
     mailing, if mailed:
