RE:  Asset Purchaser


Dear Mr. O'Gorman:

     This letter expresses our understanding  with respect to the Purchaser (the
"Purchaser")  of the resource  recovery assets (the "Assets ") of Enviro Dynamic
Systems, Inc., a Nevada Corporation  ("Seller") by Bio Solutions  Manufacturing,
Inc., a New York corporation,  ("Purchaser").  After the acquisition, the Assets
will be transferred to a subsidiary of Purchaser (the "Subsidiary").

           In connection with the Purchase we have the following understandings:

1. Purchaser  Price.  EDSI will receive a total of 500,000 shares of Purchaser's
$0.001 par value  common  stock (the  "Purchaser  Shares") in  exchange  for one
hundred percent (100%) of the Assets of Seller.


2.  Unregistered  Shares.  The Purchaser Shares will not be registered under the
Securities  Act of 1933  (the  "Securities  Act") and will be  legended  to that
effect  with a two year  lock-up  agreement.  Purchaser  will remove such legend
after  such a period,  if in the  opinion of counsel  reasonably  acceptable  to
Purchaser, the Purchaser Shares, or any portion of them, can be sold pursuant to
an exemption from the provisions of the Securities Act and any applicable  state
securities law.


3. Conditions.  The intent of Purchaser and Seller to consummate the transaction
described herein is subject to the following:


     a.  Execution  of a  Definitive  Agreement.  There shall be executed  among
     Purchaser  and  Seller,  a  definitive   agreement  covering  the  proposed
     transaction  under the terms and  conditions  set forth in this  letter and
     such further terms, provisions, agreements, covenants,  representations and
     warranties satisfactory to the parties,  including without limitation:  (i)
     general  warranties as to the  contracts,  commitments,  lease  obligation,
     trademarks  and debts of  Purchaser  and Seller  and (ii)  representations,
     indemnifications  and covenants  which shall survive the effective  date of
     the


                                        1




     transaction  and which will, in the opinion of the parties,  be adequate to
     protect their respective interests.

     b.  Litigation.  Neither  Purchaser nor Seller shall be subject to material
     litigation,  which would cause any party, in its sole discretion, to decide
     that  the  party  subject  to such  litigation  has a  material  contingent
     liability.

     c. Director and Shareholder Approval.  All necessary approvals of the Board
     of  Directors  and  Shareholders  of  Purchaser  and Seller shall have been
     obtained.

     d.  Preservation  of Assets and  Business.  Pending the closing date of the
     proposed   combination,   neither  Purchaser  nor  Seller  will  incur  any
     indebtedness  other than in the  ordinary  course of business  and will not
     commit to any  material  undertakings,  programs  or  projects,  other than
     pursuant  to  existing  agreements,  which  would have a material  negative
     impact on their balance  sheets  without the prior  written  consent of the
     other party.  Other than paying current  liabilities,  Purchaser and Seller
     will operate their businesses in a manner  consistent with the conservation
     of their assets, including their cash reserves.

     e. Consents and Releases.  Prior to the  consummation of the proposed Asset
     Purchase,  Purchaser  and Seller will each obtain all written  consents and
     releases of all persons deemed  necessary by either  Purchaser or Seller in
     connection with the consummation of the proposed transaction.


4. Expenses of Parties. Purchaser and Seller shall each bear their own costs and
expenses incurred in connection with the proposed transaction.


5.  Public  Announcement.  If  required,  upon the  execution  of this Letter of
Intent,  Purchaser  will  prepare a public  announcement  to be submitted to the
media in such form and containing such  information as approved by Purchaser and
Seller.


6. Other Matters.

     a. The Acquisition will be subject to such approvals,  which in the opinion
     of counsel for the parties, are necessary to effect the Purchase.

     b. The understandings  and agreements  reflected in this letter are subject
     to  the   execution  and  delivery  of  documents  in  form  and  substance
     satisfactory to Purchaser and Seller and to their respective counsel. There
     shall be no legal obligation upon any party until the Purchase Agreement is
     completed and executed by the parties, and then only in accordance with its
     terms.

     c. Purchaser and Seller agree that until this transaction has been publicly
     disclosed  as per  paragraph  5 hereof,  not to disclose  their  intentions
     except to their directors,  advisors and counsel.  Further,  neither Seller
     nor their  affiliates  will make any  transactions in stock of either party
     unless such transaction is first disclosed and


                                        2




     approved in writing by the parties hereto or has previously been agreed to.
     Seller  agrees to maintain  all  information,  records and  documents  in a
     confidential manner.

     d.  Unenforceablity.  The  expressions  of intent set forth in this letter,
     although  containing an agreement in principle between Purchaser and Seller
     to  the  proposed  transaction,  shall  not  be  considered  as  a  binding
     commitment on either  Purchaser and Seller,  but rather as an indication of
     their desire to consummate  the  transaction  upon the terms and conditions
     generally  outlined  herein.  Consequently,  there shall be no  enforceable
     obligation  on the part of  Purchaser or Seller with respect to the matters
     contained in this letter until a definitive agreement covering the proposed
     combination as outlined herein has been fully and properly  executed by all
     parties concerned and requested documents have been provided.


     If this letter  reflects your  understanding,  please  execute the enclosed
copy where indicated and return to BSLM for this agreement to become  effective.
Please note that an executed  facsimile copy is acceptable with an original copy
deposited in the United States Mail on the same day.


Sincerely,



BIO SOLUTIONS MANUFACTURING, INC.
