        to the Chief Executive Officer of JMAR. Schiele's primary
        responsibilities shall be for maximizing the profitability of JMAR's
        operating divisions consistent with the achievement of new product
        line/emerging business area development milestones set forth in the
        Company's annual and strategic business plans which are updated yearly,

3.      Signing Bonus. JMAR shall grant Schiele a $20,000 signing bonus (the
        "Signing Bonus") in consideration for Schiele starting employment no
        later than December 1, 1998. The Signing Bonus is payable immediately or
        will be deferred at Schiele's request and may be payable in cash or JMAR
        shares of common stock at Schiele's election. In the event that this
        Agreement is terminated prior to December 1, 2000 by JMAR pursuant to
        Paragraph 7.2 or by Schiele for any reason other than pursuant to
        Paragraph 7.3, then Schiele shall return to JMAR that portion of the
        Signing Bonus which is equal to the product of $833.33 multiplied by the
        number of calendar months remaining until December 1, 2000.

4.      Initial Stock Options/Future Stock Options. JMAR shall grant Schiele
        options to purchase 150,000 shares, consisting of (i) incentive stock
        options ("ISO's") to purchase 100,000 shares of JMAR common stock
        pursuant to the terms of JMAR's 1991 Employee Stock Option Plan, a copy
        of which is delivered herewith, and (ii) non-qualified options to
        purchase 50,000 shares of Common Stock, outside of the 1991 Employee
        Stock Option Plan ("NQSO's"). The ISO's will vest in equal amounts at
        the end of each of the first three years after the start date of
        Schiele's employment and the exercise price of the ISO's will be equal
        to the average closing prices of JMAR Common Stock for the five trading
        days prior to the date of the grant. The NQSO's shall have terms similar
        to the warrants granted to employees under the JMAR Management Incentive
        Warrant Plan, as described in Attachment 1 hereto. The other terms of
        the options shall be contained in JMAR's standard stock option
        agreement, which shall also contain a provision that immediately vests
        all options granted to Schiele in the event that a third party should
        acquire a controlling interest in JMAR.

5.      Performance Bonus Plan. JMAR shall provide to Schiele as annual
        executive bonus plan that, based upon Company performance, has the
        potential of paying Schiele an additional 75% of annual salary.

6.      Relocation Benefits/House-hunting/Temporary Living Expenses. JMAR will
        reimburse Schiele for reasonable, actual expenses involved in moving his
        residences from the present locations in Norwood, MA and Portland, OR to
        Southern California pursuant to JMAR's standard Relocation Policy. In
        addition, JMAR will reimburse Schiele for the cost of four (4)
        house-hunting trips for Schiele and his "significant other" (from
        Portland, OR). JMAR will also reimburse Schiele for up to four months
        temporary living expense during the relocation process. These expenses
        may include but are not limited to airfare, car rental and hotel/motel.

7.      Employment at Will; Salary Continuation Payments.

        7.1     Schiele's employment will be "at-will" and may be terminated at
                any time, for any reason, by either Schiele or JMAR. If JMAR
                terminates Schiele for any reason other than pursuant to
                Paragraph 7.2 below, Schiele shall become entitled to receive an
                amount ("Salary Continuation Payments")

                equal to twelve (12) months salary (subject to earlier
                termination upon the occurrence of an event specified in
                Paragraph 7.2), payable commencing on the date of such
                termination at the rate and times as such compensation would
                have been payable to Schiele had this Agreement not been
                terminated pursuant to this Paragraph 7.1. In addition to the
                payment of such Salary Continuation Payments, JMAR shall, at its
                expense, continue coverage under those insurance policies in
                which Schiele participates for which COBRA coverage is available
                for the twelve month period during which the Salary Continuation
                Payments are made (the "Continued Insurance Coverage").

        7.2     Notwithstanding the provisions of Paragraph 7.1 above, this
                Agreement shall terminate (without any right to Salary
                Continuation Payments or Continued Insurance Coverage) upon the
                occurrence of any of the following events: (a) the death of
                Schiele; (b) the incapacity or disability of Schiele, which
                renders him unable to perform substantially all of the services
                contemplated by this Agreement for a continuous period of sixty
                (60) days; (c) the commission of an act of fraud, dishonesty in
                a matter which is material to his employment, or embezzlement by
                Schiele; (d) the willful neglect by Schiele in the performance
                of the services contemplated by this Agreement in such manner as
                to provide reasonable cause for terminating his services; or (3)
                the substantial breach by Schiele of any of the covenants or
                obligations under this Agreement and such breach provides
                reasonable cause for JMAR to terminate this Agreement; provided
                that, in order to terminate this Agreement pursuant to clauses
                (d) and (e) of this Paragraph 7.2, JMAR shall have given thirty
                (30) days written notice of termination to Schiele and Schiele
                shall have failed to fully cure or correct such willful neglect
                or breach within the thirty days immediately following such
                notice.

        7.3     This Agreement may be terminated by Schiele on thirty (30) days
                written notice of termination to JMAR if JMAR breaches any of
                its covenants or obligations under the Agreement and such breach
                provides reasonable cause for Schiele to terminate this
                Agreement and in such event Schiele shall also be entitled to
                the Salary Continuation Payments and Continued Insurance
                Coverage in the manner provided in Paragraph 7.1 above; provided
                that, in order to terminate this Agreement pursuant to this
                provision, JMAR shall have failed to fully cure or correct such
                breach within the thirty days immediately following such notice.
