                  (iii) An amount equal to three (3) years of Officer's annual
            base salary, based upon Officer's base Salary as in effect on the

            Termination"), payable on the Company's regular payroll dates over

                  2.4.3 The Corporation shall, promptly upon submission by
            Officer of supporting documentation, pay or reimburse to Officer all

            provisions of this Section 2.4, benefits shall not be available
            under any of such plans because Officer is no longer an employee of
            the Corporation, the Corporation itself shall, to the extent
            necessary, pay or provide for payment of such benefits to Officer
            and/or Officer's family, in each case at the time such payments

            Officer shall not accrue any further benefits other than those
            required by law and will achieve vested status in any other benefits
            offered by the Corporation under this Agreement or any other benefit
            plan.

            2.5 Disability. If, during the term of this Agreement, Officer, in
the reasonable judgment of the Board of Directors of the Corporation (which
conclusion by such Board shall be principally based upon the full availability
of benefits of the disability policy referred to below), has failed to perform
his duties under this Agreement on account of illness or physical or mental
disability, which condition renders Officer incapable of performing the duties
of this office, and such condition continues for a period of more than six (6)
months, the Corporation shall have the right to terminate Officer's employment
hereunder by written notification to Officer and payment to Officer of all
accrued compensation to the date of termination. The Company agrees to purchase
and maintain at its own expense during the Employment Period a long-term
disability insurance policy that provides compensation upon disability of
Officer on the same terms as is generally made available to employees of the

pay to his estate all accrued compensation to the date of termination. The
Company agrees to purchase and maintain at its own expense during the Employment
Period a life insurance policy that provides a death benefit to the estate or
designated

<PAGE>

beneficiary of Officer on the same terms as is generally made available to
employees of the Corporation.

            2.7 Merger or Acquisition. This Agreement shall not be deemed
terminated by reason of the change of control of the majority ownership of the
Corporation for the purpose of merger or acquisition if Officer is offered
employment with any concern or undertaking resulting from the merger or
acquisition on terms and conditions not less favorable than the terms of this
Agreement.

            2.8 Termination Upon Expiration of Employment Period. If (a) Officer
shall voluntarily terminate his employment hereunder in accordance with Section
2.3 hereof, or (b) either the Corporation or Officer shall elect to terminate
Officer's employment hereunder upon the expiration of the Employment Period by
giving timely Notice of Termination to the other; then, as of the date of the
expiration of the Employment Period ("Expiration Date"), Officer shall not
accrue any further benefits other than those required by law and shall not
achieve vested status in any other benefits offered by the Corporation under
this Agreement or any other benefit plan, and the Corporation shall have no
further obligation under this Agreement, except as follows:

                2.8.1 The Corporation shall pay to Officer the following
            amounts:

            days after the Expiration Date; and

                  (iii) An amount equal to three (3) years of Officer's annual
            base salary, based upon Officer's base Salary as in effect on the
            Expiration Date ("Base Salary Upon Expiration"), payable on the
            Company's regular payroll dates over the six (6) year period
            commencing on the Expiration Date at the rate of 50% of Officer's
            Base Salary Upon Expiration; and

            Date which are payable under Section 3.3.2; and

                2.8.3 For a period of three (3) years from the Expiration Date,
            Officer and his family shall be permitted to continue to participate
            in all life, accidental death, disability, medical, dental and other
            insurance plans of the Corporation If, despite the provisions of
            this Section 2.8.3, benefits shall not be available under any of
            such plans because Officer is no longer an employee of the
            Corporation, the Corporation itself shall, to the extent necessary,
            pay or provide for payment of such benefits to

                                       8

            shall be in full and complete in satisfaction of all obligations of
            the Corporation owed to Officer pursuant to this Agreement. After

            forth herein.

      3. Compensation.

            3.1 Base Salary. During the Employment Period, the Corporation shall
pay to Officer as compensation for the services to be performed by Officer a
salary at the annual rate of $325,000 in U.S. currency. Such salary shall be
subject to further annual upward adjustment at the discretion of the Board.
Officer's salary shall be payable in equal semi-monthly installments on or
before the 15th day and the last day of each month during which Officer is
employed. Should Officer be employed for only a portion of any month, Officer's
salary shall be prorated to reflect the actual days of employment during such
month.

            3.2 Incentive Compensation. The Corporation shall establish an
Incentive Compensation Fund to be administered by the Compensation Committee of
the Board of Directors. The Compensation Committee shall determine the
distribution of the payment of incentive compensation (the "Incentive
Compensation") to officers and key employees of the Corporation as follows:

                3.2.1 In the event that the Corporation enters into a merger or
            other transaction which results in a change of control, the sale of
            substantially all of its assets or similar transactions, the
            Compensation Committee shall determine the amount of Incentive
            Compensation pursuant to the formula set forth in section 3.2.2 and
            shall immediately upon consummation of such transaction, distribute
            100% of the Incentive Compensation to each officer or employee who
            had, in the Compensation Committee's judgment, made substantial
            contribution to the Corporation's success and increase in value. In
            the event of the sale of a significant subsidiary, or substantially
            all of the assets of a significant subsidiary, a similar pro rata
            distribution shall be required. Such payments shall be made on a pro
            rata basis in the event of a death, disability or termination (other
            than for cause) or at such other times as the Compensation Committee
            may determine. The Compensation Committee may, in its discretion,
            determine that up to 50% of any payment be made in shares of Common
            Stock.

                3.2.2 The total amount of Incentive Compensation available for
            distribution shall be determined according to the following formula
            (an example of which is attached hereto as Exhibit A):

                                       9
<PAGE>

                        [Fair Market Value per Common Stock Equivalent ("FMV")
                        Base Price per Common Stock Equivalent ("BP")] X
                        Outstanding Common Stock Equivalents X the applicable
                        percentage as set forth below:

                          The portion of FMV equal to or less than
                          the ratio of FMV to BP; plus                        0%

                          The portion of FMV falling in the range of
                          1 to 3 for the ratio of FMV to BP; plus            10%

                          The portion of FMV falling in the range of
                          3 to 4 for the ratio of FMV to BP; plus            15%

                          The portion of FMV which exceeds 4 for
                          the ratio of FMV to BP                             20%

                3.2.3 BP shall mean $10.04 per Share, adjusted to reflect stock
            dividends, stock splits and similar events occurring after the date
            hereof.

                3.2.4 For purposes hereof, FMV shall be defined as the actual or
            allocated transaction price per equivalent share of Common Stock
            (the total number of shares of Common Stock outstanding plus the
            balance of dilutive shares of Common Stock into which outstanding
            shares of Preferred Stock are convertible), or the average closing
            bid price of the Corporation stock during the 30 days preceding the
            determination date, or such other price as may be reasonably
            determined by the Compensation Committee. In the event of a sale of
            a significant subsidiary or substantially all of the assets of a
            significant subsidiary, then FMV and the part of the BP attributable
            to that significant subsidiary shall be reasonably determined by the
            Compensation Committee.

                3.2.5 Officer's right to participate in the Incentive
            Compensation Fund shall be fully vested as of the date hereof.

      3.3 Benefits. During the Employment Period and for any other time required
by law, Officer shall be entitled to participate, upon the standard terms and
conditions of such plans in all regular and key employee benefit plans
established by the Corporation for its salaried employees, including, without
limitation, the following:

                3.3.1 Stock Options. The Corporation shall use its best efforts
            to establish and maintain one or more stock option plans (the "Stock
            Option Plans") for the purpose of granting options to key employees,
            management and directors. The Stock Option Plans shall provide for
            incentive stock options and such other options and awards as the
            Board of Directors, in its discretion, may determine. The Stock
            Option Committee or other appropriate Committee of the Board of
            Directors shall from time

                                       10

            to time grant to Officer options to purchase shares of Common Stock
            or other awards under the Stock Option Plans as it shall in its
            discretion deem appropriate.

                3.3.2 Expenses. The Corporation shall reimburse Officer for any
            reasonable business expenses wholly, exclusively and necessarily
            incurred by him in the performance of his duties for the

            reasonable cost incurred to establish or maintain membership in any
            professional association necessary to maintain Officer's
            professional qualifications. Officer shall be required to provide
            reasonable evidence of expense prior to reimbursement.

            terminate Officer's employment without "cause" (as defined in
            Section 2.2), or the employment of Officer shall be terminated by
            Officer for "Good Reason" (as defined in Section 3.4.3):

            Officer, all amounts of such compensation previously deferred and
            not yet paid by the Corporation; and

                (b)The Corporation shall, promptly upon submission by Officer of

            provisions of this Section 3.4.1(c), benefits shall not be available

            for any reason or by Officer for Good Reason, shall be communicated
            by Notice of Termination to the other party hereto. For purposes of

            this Section 3.4.

      4. Confidentiality. The Officer shall not, during the Employment Period,
or at any time thereafter, directly or indirectly use, divulge, furnish or make

projects, plans, techniques, methods, reports, customer names or lists,
financial or sales information or other material relating to the business or
activities of the Corporation. Officer, upon leaving the employ of the

or material relating to the business or activities of the Corporation.

      5. Inventions, Discoveries and Improvements. All inventions, discoveries
and improvements, whether patentable or unpatentable, made, devised or

relating or pertaining in any way to the business of his employment, shall
promptly be disclosed in writing to the Board of Directors and are to rebound to
the benefit of the Corporation and become and remain its sole and exclusive
property. Officer agrees to execute any assignments to the Corporation or its
nominee of his entire right, title and interest in and to any such inventions,
discoveries and improvements and to execute any other instruments and documents
requisite to or desirable in applying for and obtaining patents with respect
thereto in the United States and in all foreign countries, at the request and
expense of the Corporation. Officer further agrees to cooperate to the extent
and in the manner requested by the Corporation in the prosecution or defense of
any patent claims or any litigation or other proceeding involving any

      6. Covenant Not to Compete. During the Employment Period and (i) for a
period of three (3) years after the Employment Period, or (ii) if the
Corporation for any reason defaults for sixty (60) days in its severance
obligations to Officer hereunder, for a period after the Employment Period
ending upon the expiration of such default period (the "Restricted Period"),
Officer shall not, alone, together or in association with others, as owner,
shareholder, employee, officer, director, partner, lender, investor, consultant,
principal, agent, independent contractor, co-venturer or in any other capacity,
directly or indirectly, engage in, have a financial interest in or be in any way
connected or affiliated with, or render advice or service, to, any person, firm
or business or enterprise which is in competition with any subsidiary of the
Corporation. This consent shall apply in every geographic area in the world in
which the Corporation is conducting or has conducted business at any time since

than five percent (5%) of the shares of any corporation, the shares of which are
regularly traded either on a national securities exchange, on the Nasdaq Stock
Market or in the over-the-counter market. In the event Officer is terminated by
the Corporation without cause, then the period of this covenant shall be limited
to the period of time during which Employee shall receive compensation or
benefits from the Corporation under the provisions of this Agreement.

unenforceable, invalid or void to any extent for any reason, such provision will

cancelled, and any of the terms hereof may be waived, only by a written
instrument executed by each Party or, in the case of a waiver, by the Party
waiving compliance. The failure of any Party at any time or times to require
performance of any provisions hereof shall not affect the right at a latter time
to enforce the same. No waiver by any Party of the breach of any provision
contained in this Agreement, whether by conduct or otherwise, in any one or more
instances, shall be deemed to be or construed as a further or continuing waiver
of any such breach or of any other term of this Agreement.

whatsoever, the provisions of Sections 4 through 7 shall survive such
termination.
