                           Re:  Binding Letter of Intent

Gentlemen:

         This Letter of Intent (this "Letter of Intent") shall set forth our
mutual agreement regarding a transaction (the "Transaction") whereby
Datigen.com, Inc., a Utah corporation ("Purchaser") shall purchase all right,
title and interest related to the Battery Brain Product (the "Battery Brain
Product") owned by Purisys, Inc., a New Jersey corporation ("Seller").


1.     Purchase and Sale of the Assets. Upon execution and delivery of a
       definitive Purchase Agreement between Purchaser and Seller, Seller shall
       sell, convey, transfer, assign and deliver possession to Purchaser, and
       Purchaser agrees to purchase and acquire from Seller, all of Seller's
       right, title and interest in and to all of the assets specified below
       (the "Assets"), free and clear of any and all liens, pledges, claims,
       charges, actions, suits, proceedings, hypothecation, security interests,
       preemptive rights, right of first refusal or other rights or restrictions
       or encumbrances of any kind ("Liens"):


       (a)    all of the Seller's intellectual property relating to the Battery
              Brain Product ("Seller's Intellectual Property");


       (b)    the goodwill associated with or attributable to the Seller's
              Intellectual Property;


       (c)    all of the rights of the Seller under any and all contracts with
              customers for the Battery Brain Product;


       (d)    all of the rights of the Seller under any and all customer
              purchase orders;


       (e)    all of the inventory associated with the Battery Brain Product;


<PAGE>

       (f)    the equipment that the Seller used or uses for the development,
              production and testing of the Battery Brain Product, and which is
              owned by or licensed to or registered in the name of Seller (the
              "Equipment"); and

       (g)    any and all other properties or assets of all other character or
              description, tangible or intangible, owned by Seller or Aharon Y.
              Levinas ("Principal") and used or held for use in connection with
              the Battery Brain Product.

         2. Consideration. In exchange for the Assets, Purchaser shall pay to
Seller: (i) one hundred thousand ($100,000) dollars (the "Cash Consideration");
and (ii) the number of shares (rounded to the nearest whole share) of the Common
Stock of the Purchaser, to be issued in accordance with the instructions of the
Seller, which will constitute, as of the closing date, twenty (20%) percent of
the issued and outstanding shares of Common Stock of the Purchaser on a fully
diluted basis (the "Equity Consideration").

         3. No Assumption of Liabilities. Purchaser will not assume any
liabilities, costs, debts, claims and obligations of Seller relating to the
Assets or otherwise. All liabilities relating to the Assets shall remain the
sole responsibility of, and shall be retained, paid, performed or discharged
solely by, the Seller, other than the liabilities of the Battery Brain Product
which are specifically assumed by the Purchaser in the definitive Purchase
Agreement.

         4. Appointment of CTO. The board of directors of Purchaser shall cause
Principal to be appointed as the Chief Technology Officer of the Purchaser
within 90 days after the date of the definitive Purchase Agreement, in
accordance with the provisions of a consulting agreement to be executed between
Purchaser and Mr. Levinas.

         5. Directors. Following the closing of the Transaction, the board of
directors of the Purchaser shall consist of five (5) members. Principal shall be
entitled to appoint two (2) representatives to the board of directors of the
Purchaser (the "Levinas' Directors"). Upon any retirement, resignation, death or
disability of any Levinas' Director, Principal shall have the sole right to
appoint a replacement.

         6. Registration Rights. Purchaser and Principal mutually agree to
negotiate, in good faith, an agreement regarding the registration rights of
Levinas for the shares of Common Stock of the Purchaser constituting the Equity
Consideration. Principal shall be entitled to equal registration rights with the
controlling shareholders of the Purchaser, pro rata in accordance with their
holdings in the Purchaser, subject to a lock-up agreement.

         8. Due Diligence. Seller shall provide the officers, independent

advisors and the Principal) or any other person acting on behalf of Seller, to,
directly or indirectly, (i) solicit, negotiate and/or accept any offer to
acquire any of Seller's securities and/or all or substantially all of its assets
until the execution and delivery of definitive agreements with respect to the
Transaction and (ii) acquire any shares of Purchaser, whether such acquisition
is made in the public markets or via a private sale.

         10. Conduct of Business Prior to Closing. Until the closing of the
Transaction, or termination of this Letter of Intent as provided in paragraph 14
hereof, Seller and Principal shall use their best efforts to preserve and

securities laws.



            14. Termination. The parties agree to negotiate in good faith the
terms and conditions of the definitive agreements with respect to the

participate in, the drafting of each provision hereof.


         If the foregoing accurately sets forth our agreement, please execute
where indicated below and return a fully executed copy of this Letter of Intent
to our attention, whereupon this Letter of Intent shall become a valid and
binding agreement between us in accordance with the terms hereof.
