        plan and various stock options plans.  Filing of all required

        coordination of stock repurchase programs, and tracking of stock
        issuances and reserved shares.

             (e)  Services in addition to those enumerated in subsections
        1.1(a) through 1.1(d) above including, but not limited to,
        routine legal and other administrative activities, Corporate
        information and treasury and other financial services as
        reasonably requested by Subsidiary.

             1.2  For performing general services of the types described
        above in Paragraph 1.1, Thermo will initially charge Subsidiary
        an annual fixed fee equal to 1.0% of the gross revenues of
        Subsidiary for the fiscal year in which such services are
        performed (such amount to be prorated on a daily basis for any
        partial year), which fee is intended to compensate Thermo for
        Subsidiary's pro rata share of the aggregate costs actually
        incurred by Thermo in connection with the provision of such
        services to all recipients thereof.  The fee set forth in the
        preceding sentence may be adjusted from time to time by mutual
        agreement of Thermo and Subsidiary.

             1.3  In addition to the foregoing services, certain specific
        services are made available to Subsidiary by Thermo on an
        as-requested basis.  These may include, but are not limited to,
        services specifically requested by Subsidiary or services which,
        in Thermo's judgment, are not routine administrative services or
        create unusual burdens or demands on Thermo's resources, such as
        litigation support, acquisition and offering support services
        (including legal services), corporate development, tax audit
        support or public or investor relations services other than
        routine shareholder communications.  Thermo will charge
        Subsidiary the costs actually incurred  (including overhead and
        general administrative expenses) for such services that are
        requested by Subsidiary and supplied by Thermo.

             1.4  The charges for services pursuant to Subsections 1.2
        and 1.3 above will be determined and payable no less frequently
        than on a quarterly basis.  The charges will be due when billed
        and shall be paid no later than 30 days from the date of billing.

             1.5  When services of the type described above in this
        Section 1 are provided by outside providers to Subsidiary or, in
        connection with the provision of such services out-of-pocket
        costs are incurred such as travel, the cost thereof will be paid
        by Subsidiary.  To the extent that Subsidiary is billed by the
        provider directly, Subsidiary shall pay the bill directly.  If
        Thermo is billed for such services, Thermo may pay the bill and
        charge Subsidiary the amount of the bill or forward the bill to
        Subsidiary for payment by Subsidiary.

             2.   Subsidiary's Directors and Officers.  Nothing contained
        herein will be construed to relieve the directors or officers of
        Subsidiary from the performance of their respective duties or to
        limit the exercise of their powers in accordance with the charter
        or By-Laws of Subsidiary or in accordance with any applicable
        statute or regulation.

             3.   Liabilities.  In furnishing Subsidiary with management
        advice and other services as herein provided, neither Thermo nor
        any of its officers, directors or agents shall be liable to
        Subsidiary or its creditors or shareholders for errors of
        judgment or for anything except willful malfeasance, bad faith or
        gross negligence in the performance of their duties or reckless
        disregard of their obligations and duties under the terms of this
        Agreement.  The provisions of this Agreement are for the sole
        benefit of Thermo and Subsidiary and will not, except to the
        extent otherwise expressly stated herein, inure to the benefit of
        any third party.

             4.   Term. 

             (a)  Term.  The initial term of this Agreement shall begin
        on the date of this Agreement and continue through the end of the
        current fiscal year.  This Agreement shall automatically renew at
        the end of the initial term for successive one-year terms until
        terminated in accordance with Subsection (b) below.

             (b)  Termination.  This Agreement may be terminated by
        Subsidiary at any time on thirty days prior notice to Thermo.  In
        addition, this Agreement shall automatically terminate without
        any further action by either party on the date the Subsidiary
        ceases to be a member of the Thermo Group or a participant in the
        Thermo Electron Corporate Charter.

             (c)  Termination Fee.  In the event of a termination of this
        Agreement, Subsidiary shall pay to Thermo its pro rata fee
        pursuant to Section 1.2 for the year in which the termination
        takes effect plus a termination fee equal to the fee payable
        under Section 1.2 for the most recent nine consecutive months.  

             (d)  Post-Termination Services.  Following a termination of
        this Agreement, corporate administrative services of the kind
        provided under the Agreement may continue to be provided to

                                        3PAGE
<PAGE>
        Subsidiary on an as-requested basis by the Subsidiary or as
        required in the event it is not practicable for the Subsidiary to
        provide such services or it is otherwise unable to identify
        another source to provide such services (as would be the case of
        administration of employee benefit plans and insurance programs
        sponsored by Thermo and in which Subsidiary's employees
        participate) or as otherwise required by Thermo acting in its
        capacity as majority stockholder of Subsidiary.  In the event
        such services are provided by Thermo to Subsidiary, Subsidiary
        shall be charged by Thermo a fee equal to the market rate for
        comparable services charged by third-party vendors.  Such fee
        will be charged monthly and payable by Subsidiary within thirty
        days.  The obligations of Subsidiary set forth in this Section
        4(d) shall survive the termination of this Agreement.  

             5.   Status.  Thermo shall be deemed to be an independent
        contractor and, except as expressly provided or authorized in
        this Agreement, shall have no authority to act for or represent
        Subsidiary.

             6.   Other Activities of Thermo.  Subsidiary recognizes that
        Thermo now renders and may continue to render management and
        other services to other companies that may or may not have
        policies and conduct activities similar to those of Subsidiary.
        Thermo shall be free to render such advice and other services,
        and Subsidiary hereby consents thereto.  Thermo shall not be
        required to devote full time and attention to the performance of
        its duties under this Agreement, but shall devote only so much of
        its time and attention as it deems reasonable or necessary to
        perform the services required hereunder.

             7.   Notices.  All notices, billings, requests, demands,
        approvals, consents, and other communications which are required
        or may be given under this Agreement shall be in writing and will
        be deemed to have been duly given if delivered personally or sent
