Dear Mr. Adereth:

It is my pleasure to offer you the opportunity to serve as a consultant to and

"Company") on the following terms and conditions which shall constitute your
agreement (the "Agreement") with the Company.

1. Start Date; Term: This Agreement shall become effective on August 1st 2000
      and the term shall end on the second anniversary thereof (the "Term"),
      subject to earlier termination as provided herein.

2. Duties: You shall serve as a management consultant to the Company. In this
      position, your responsibilities shall include:

      (a)   maintaining constant contact with the management of the Company;

      (b)   taking an active role in outlining the Company's business strategy
            and R&D plans; and

      (c)   monitoring the progress of the Company's management in such business
            strategy and R&D plans.

During the term of this Agreement, you shall devote such time as is reasonably
necessary to perform the duties and responsibilities referred to in this Section
1. You shall report to the Company's Chairman of the Board.

3. Directorship. On or promptly following the date of this Agreement, you
      will be elected as a member of the Board. The Company shall use its
      reasonable best efforts to cause you to be elected as a director of the
      Company at each of the Company's annual meetings of stockholders during
      the Term (as defined above).

      In the event that Noga Investments in Technologies Ltd. ("Noga") becomes
      eligible to nominate more than one director to the Board pursuant to that
      certain Letter Agreement


                                       2
<PAGE>

      dated December 17, 1999, as subsequently amended, it is understood that
      you are to be one of Noga's nominees.

4. Fees: In consideration for your consulting services, you shall receive
      consulting fee of $3,500 plus Israeli VAT (if applicable) per month, due
      on the first business day of each month, from which the Company shall
      withhold and deduct all federal and state income, social security and
      other taxes to the extent required by applicable laws. Additionally the
      company will pay you a monthly allowance of $500 plus VAT (*) to cover
      your variable expenses (without presentation of expense reports). This
      payment will be made on the first date of each month together with the
      consulting fee mentioned above. Additionally, you shall receive $500 plus
      VAT per day for each day that you are in or you are on your way to and
      from the United States in order to attend and participate at Board
      meetings or, at the request of the Company, for other business matters of
      the Company outside of Israel. Such payments will be made together with
      the consulting fee mentioned here above on the first business day of the
      month following the month of travel. The company will also pay all your
      travel food and lodging expenses during such travels at the appropriate
      level suitable to your position ( i.e. Air Travel : Business Class,
      Hotels : Executive Business standard etc.).

5. Stock Option. You shall be granted an option, under the Company's Stock
      Option Plan, to purchase 2,500,000 shares of the common stock of the
      Company, subject to the terms of the Company's Option Plan and such other
      terms as are set forth herein and in the applicable option agreement (the
      "Option"). The Option shall vest and become exercisable in four equal
      installments on each of the next six-month anniversary dates of this
      Agreement. The Option shall be exercisable at a price per share of $0.49,
      which was the average of the closing bid and ask prices of the Company's
      common stock on July __, 2000, the date on which the Option was granted,
      and shall expire five years from the date of grant. In the event of any
      inconsistencey between the terms of the Stock Option Plan and the terms of
      the Option as set forth in this Agreement (including, without limitation,
      treatment of the Option upon cessation of services), the terms of the
      Stock Option Plan shall control. The Company does not currently have
      sufficient shares available under its Option Plan or authorized in its
      charter to cover the Option. Accordingly, the Company will use its best
      efforts to obtain approval from its stockholders to increase its
      authorized shares, both under the Option Plan and in its charter, in an
      amount sufficient to cover the share issuances under the Option.
      Additionally, the Company will use its best efforts to register the
      exercise of this Option with the Securities and Exchange Commission on
      Form S-8.

      In the event of a Change in Control (as defined below), notwithstanding
      anything contained herein to the contrary, any portion of the Option that
      has not yet vested shall immediately vest and be exercisable by you within
      sixty days following the consummation of the Change in Control; provided
      however, that if you are requested to continue as a member of the Board
      following such Change in Control, only 50% of the Option will be
      considered vested and exercisable and the remaining 50% will become vested
      and exercisable six months thereafter. For purposes of this Agreement, a
      "Change in Control" of the Company shall be deemed to have occurred if (i)
      there shall be consummated (x) any consolidation or merger of the Company
      in which the Company is


                                       3
<PAGE>

      not the continuing or surviving corporation or pursuant to which the
      shares of the common stock of the Company would be converted into cash,
      securities or other property, other than a merger of the Company in which
      the holders of the common stock immediately prior to the merger have the
      same proportionate ownership of common stock of the surviving corporation
      immediately after the merger, or (y) any sale, lease, exchange or other
      transfer of all, or substantially all, of the assets of the Company, or
      (ii) the stockholders of the Company approve a plan for liquidation or
      dissolution of the Company, or (iii) any person (as such term is defined
      in Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as
      amended (the "Exchange Act") who is not currently an affiliate of the
      Company, shall become the beneficial owner (within the meaning of Rule
      13d-3 under the Exchange Act) of 50% or more of the outstanding common
      stock of the Company. Notwithstanding the foregoing, in the event the
      definition of Change in Control herein is inconsistent with the terms in
      Option Plan then such definition shall be modified so that it is
      consistent with the Option Plan.

6. Cessation of Services: In the event you shall cease to provide consulting
      services to the Company for any reason, then your compensation shall cease
      on the date of such event, except as otherwise provided herein. All
      amounts due and payable through the date of termination as defined below,
      shall be paid to you by the company within seven days of the date of
      termination.

            exercisable. In the event that your retention hereunder is

            parties with respect to the assignment of Inventions or rights to
            Inventions, nor does claim any previous, unpublished Inventions
            within the scope of this Agreement as 's own, except for the
            Inventions, if any, which has listed in Appendix A to this
            Agreement.

      6.    Undersigned certifies that there is no other contract or duty on
            Undersigned's part that would interfere with Undersigned's ability
            to provide services to the Company. Undersigned agrees that, in
            performing work for the Company, Undersigned will not knowingly use
            any patented inventions, trade secrets, confidential information or
            proprietary information obtained from third parties, including any
            prior employer or any other organization or individual. Undersigned
            will not bring onto the premises of the Company any unpublished
            document or other property containing proprietary information or
            trade secrets belonging to Undersigned's former or concurrent
            employers or companies, unless consented to in writing by said
            employers or companies.

      7.    The restrictions against competition and disclosure set forth above
            are considered by the parties to be reasonable for the purposes of
            protecting the business of the Company, its subsidiaries and its
            affiliates. However, if any such restriction is found by any court
            of competent jurisdiction to be unenforceable because it extends for
            too long a period of time or over too great a range of activities or
            in too broad a geographic area, it shall be interpreted to extend
            only over the maximum period of time, range of activities or
            geographic area as to which it may be enforceable.

      8.    The parties hereto understand and intend that each restriction
            agreed to by Undersigned herein shall be construed as separable and
            divisible from every other restriction,


                                   Exhibit 1
                                       2

            and the un enforceability, in whole or in part, of any such
            restriction, in any jurisdiction, shall not affect the
            enforceability of such restriction in any other jurisdiction or of
            the remaining restrictions in any jurisdiction, and that one or more
            or all of such restrictions may be enforced in whole or in part as
            the circumstances warrant.

      9.    Undersigned acknowledges that the Company is relying upon the
            representations and covenants contained in this Agreement as an
            inducement to permit Undersigned to provide services in connection
            therewith to permit Undersigned to have continued access to
            Information and Trade Secrets.

      10.   This Agreement shall be governed by the laws of the State of New
            York (without reference to its rules as to conflicts of laws).
            Undersigned and the Company specifically consent to the jurisdiction
            of the courts of the State of New York or the United States District
            Courts for the Southern or Eastern Districts of New York over any
            action or arbitration arising out of or related to this Agreement
            and consent to the service of process in any such action or
            proceeding by certified or registered mailing of the summons and
            complaint therein directed to Undersigned at the address of
            Undersigned's residence (as reflected in the Company's records or
            otherwise designated by Undersigned on 30 days' prior written notice
            to the Company) and to the Company's designated agent for service of
            process.
