        Employer requires Executive to relocate to a location outside of the
        metropolitan Roanoke area and Executive fails to so relocate, such
        failure shall not be deemed to be grounds for termination for "Cause"

             2.1.  Salary.  Employer will pay to Executive, and Executive will

          3.  Termination of Employment.
 
             3.1.  Termination.  Executive's employment by Employer pursuant to
        this Agreement shall commence on the date hereof and will continue until
        the first anniversary of the date of this Agreement. Thereafter, it will
        continue for successive one-year periods commencing on April 1 of each
        subsequent year; provided, however, that either party may elect to
        terminate this Agreement as of March 31, 1997, or as of any subsequent
        March 31, by written notice to such effect delivered to the other party
        at least 90 days prior to such termination date. Upon termination of
        Executive's employment with Employer pursuant to Sections 3.2.2 through
        3.2.6 hereof, inclusive, Executive will be released from any duties and
        obligations hereunder (except those duties and obligations set forth in
        Sections 4, 5.11, 5.12 and 5.13 hereof), and the obligations of Employer
        to Executive will be as set forth in Section 3.3 hereof.
 
             3.2.  Events of Termination.  Executive's employment with Employer
        will terminate upon the occurrence of any one or more of the following
        events:
 
                3.2.1.  Death.  In the event of the Executive's death,
           Executive's employment will terminate on the date of death.
 
                3.2.2.  Disability.  In the event of Executive's Disability (as
           hereinafter defined), Employer will have the option to terminate
           Executive's employment by giving a notice of termination to
           Executive. The notice of termination shall specify the date of
           termination, which date shall not be earlier than thirty (30) days
           after the notice of termination is given. For purposes of this
           Agreement, "Disability" means the inability of Executive to
           substantially perform her duties hereunder for 90 days out of 180
           consecutive days as a result of a physical or mental illness, all as
           determined in good faith by the Board.
 
                3.2.3.  Termination by Employer for Cause.  Employer may, at its
           option, terminate Executive's employment for "Cause" based on
           objective factors determined in good faith by a majority of the Board
           by giving a notice of termination to Executive specifying the reasons
           for termination, and if Executive shall fail to cure same within ten
           (10) days of her receiving the notice of termination, her Employment
           shall terminate at the end of such ten (10) day period; provided,
           that in the event the Board in good faith determines that the
           underlying reasons giving rise to such determination cannot be cured,
           then said cure period shall not apply and Executive's employment
           shall terminate on the date of Executive's receipt of the notice of
           termination. "Cause" shall mean (i) Executive's conviction of, guilty
           plea to, or confession of guilt of, a felony, (ii) dishonest or
           illegal conduct or misconduct or malfeasance by Executive in the
           performance of services for or on behalf of the Employer, or other
           conduct detrimental to the business, operations or reputation of the
           Employer, regardless of whether such conduct is within the scope of
           Executive's duties, (iii) failure by Executive to perform her duties,
           as assigned to her by the Chief Executive Officer, President,
           Chairman or the Board from time to time, (iv) violation by Executive
           of the covenants set forth in this Agreement, (v) the filing by or
           against Executive of any bankruptcy, insolvency or reorganization
           proceeding and (vi) except as may be permitted herein, disclosure of
           Confidential Information (as defined in Section 4.1 hereof) without
           the prior written consent of Employer.
 
                3.2.4.  Without Cause By Employer.  Employer may, at its option,
           terminate the Executive's employment for any reason whatsoever (other
           than for the reasons set forth above in this Section 3.2) by giving a
           notice of termination to Executive, and Executive's employment shall
           terminate on the later of the date the notice of termination is given
           or the date set forth in such notice of termination.
 
                                        2
   3
 
                3.2.5.  Employer's Material Breach.  Executive may, at her
           option, terminate the Executive's employment upon Employer's material
           breach of this Agreement by giving Employer written notice of such
           breach (which notice will identify the manner in which Employer has
           materially breached this Agreement) and if such breach is not cured
           within thirty (30) days of Employer receiving such written notice,
           the Executive's employment shall terminate at the end of such thirty
           (30) day period. Employer's "Material Breach" of this Agreement shall
           mean (i) the failure of Employer to pay Base Salary or additional
           compensation hereunder in accordance with this Agreement or (ii) the
           assignment to Executive without Executive's consent of duties
           substantially inconsistent with her duties as set forth in Section
           1.2 hereof. Notwithstanding the foregoing, Employer shall have the
           right to remove Executive's title and duties as Treasurer of the
           Corporation, and such change shall not be deemed to be a material
           breach by Employer of this Agreement. Employer shall not be entitled
           to the payments provided in Section 3.3.2 hereof solely as a result
           of such change in title and duties.
 
                3.2.6.  Without Cause By Executive.  Executive may terminate the
           Executive's employment for any reason whatsoever by giving a notice
           of termination to Employer. The Executive's employment shall
           terminate on the earlier of (i) the date, following the date of the
           notice of termination, upon which a suitable replacement for
           Executive is found by Employer, or (ii) 5 days after the date of
           receipt by Employer of the notice of termination.
 
             3.3.  Certain Obligations of Employer Following Termination of the
        Executive's Employment. Following the termination of Executive's
        employment under the circumstances described below, Employer will pay to
        Executive in accordance with its regular payroll practices the following
        compensation and provide the following benefits in full satisfaction and
        final settlement of any and all claims and demands that Executive now
        has or hereafter may have hereunder a gainst Employer:
 
                3.3.1.  Death; Disability.  In the event that Executive's
           employment is terminated by reason of Executive's death or
           Disability, Executive or her estate, as the case may be, shall be
           entitled to the following payments:
 
                    (i) Base Salary through the date the Executive's employment
               is terminated; and
 
                    (ii) Employer shall pay to Executive or her estate, as the
               case may be, the amounts and shall provide all benefits generally
               available under the employee benefit plans, and the policies and
               practices of Employer, determined in accordance with the
               applicable terms and provisions of such plans, policies and
               practices, in each case, as accrued to the date of termination or
               otherwise payable as a consequence of Executive's death or
               Disability.
 
                3.3.2.  Without Cause by Employer; Material Breach by
           Employer.  In the event that the Executive's employment is terminated
           by Employer pursuant to Section 3.2.4 hereof or by Executive pursuant
           to Section 3.2.5 hereof, Executive shall be entitled to the following
           payments:
 
                    (i) Base Salary through the date the Executive's employment
               is terminated; and
 
                    (ii) a pro-rata portion of any amounts Executive would be
               entitled to under the MICP, if any, accrued on or prior to date
               Executive's employment is terminated for any reason hereunder.
 
                    (iii) continuing payments of Base Salary, payable in
               accordance with the regular payroll practices of Employer, for
               six (6) months following the date of termination of Executive's
               employment.
 
                3.3.3.  Termination by Executive Without Cause or by Employer
           for Cause.  In the event the Executive's employment is terminated by
           Executive pursuant to Section 3.2.6 hereof or by Employer pursuant to
           Section 3.2.3 hereof, Executive shall be entitled to no further
           compensation or other benefits under this Agreement except as to that
           portion of any unpaid Base Salary and other benefits accrued and
           earned by her hereunder up to and including the effective date of
 
                                        3
   4
 
           such termination. In addition, Executive shall be entitled to receive
           any additional compensation earned but not yet paid with respect only
           to any calendar year prior to the calendar year of termination.
 
             3.4.  Nature of Payments.  All amounts to be paid by Employer to
        Executive pursuant to this Section 3 are considered by the parties to be
        severance payments. In the event such payments are treated as damages,
        it is expressly acknowledged by the parties that damages to Executive
        for termination of employment would be difficult to ascertain and the
        above amounts are reasonable estimates thereof.
 
          4.  Confidentiality; Nonsolicitation; Non-Compete.
 
             4.1.  Confidential Information Defined.  "Confidential Information"
        means any and all information (oral or written) relating to Employer or
        any person controlling, controlled by, or under common control with
        Employer or any of their respective activities, including, but not
        limited to, information relating to: discoveries, innovations,
        chemistry, patents, patent applications, know how, secret processes,
        research, test procedures and results, machinery and equipment;
        manufacturing processes; financial information; products; identity and
        description of materials and services used; purchasing; costs; pricing;
        customers and prospects; advertising, promotion and marketing;
        trademarks and trademark registrations; copyrights and copyright
        registrations; and information pertaining to any governmental
        investigation, except such information which can be shown by Executive
        to be generally in the public domain (such information not being deemed
        to be in the public domain merely because it is embraced by more general
        information which is in the public domain), other than as a result of a
        breach of the provisions of Section 4.2 hereof.
 
             4.2.  Nondisclosure of Confidential Information.  Executive will
        not, at any time (other than as may be required or appropriate in
        connection with the performance by her of her duties hereunder) directly
        or indirectly, use, communicate, disclose or disseminate any
        Confidential Information in any manner whatsoever (except as may be
        required under legal process by subpoena or other court order; provided,
        that, Executive will take reasonable steps to give Employer sufficient
        prior written notice in order to contest such requirement or order).
 
             4.3.  Certain Activities.  Executive will not while employed by
        Employer and thereafter, directly or indirectly, hire, offer to hire,
        entice away or in any other manner persuade or attempt to persuade any
        officer, employee, agent, lessor, lessee, licensor, licensee, customer,
        prospective customer, supplier or shareholder or prospective shareholder
        of Employer to discontinue or alter her or its relationship with
        Employer.
 
             4.4.  Covenant Not to Compete.  During the Executive's employment
        and for a period of two (2) years after the termination of Executive's
        employment, Executive will not directly or indirectly engage in
        competition with Employer by being associated with any competitor of
        Employer that sells or offers to sell any products or services which
        compete with the products or services offered or sold by Employer or
        being developed by Employer for sale at the time of termination of the
        Executive, or induce or attempt to induce, directly or indirectly, any
        then current or potential customer of Employer to cease doing business,
        in whole or in part, with Employer or solicit business of any such
        customer for any products or services of any competitor of Employer
        which compete with the products or services offered or sold by Employer
        or being developed by Employer for sale at the time of termination of
        the Executive. Notwithstanding the foregoing, in the event Executive's
        employment is terminated by Employer without Cause or due to Employer's
        Material Breach of this Agreement, this Section 4.4 shall only apply to
        the products or services offered or sold by Employer that relate to its
        SurfaceCasting technology.
 
             4.5.  Injunctive Relief.  Executive acknowledges and agrees that
        (a) Employer will be irreparably injured in the event of a breach by
        Executive of any of her obligations under this Section 4; (b) monetary
        damages will not be an adequate remedy for any such breach; (c) Employer
        will be entitled to injunctive relief, in addition to any other remedy
        which it may have, in the event of any
 
                                        4
   5
 
        such breach, including, but not limited to, termination of the
        Executive's employment for Cause; and (d) the existence of any claims
        which Executive may have against Employer, whether under this Agreement
        or otherwise, will not be a defense to the enforcement by Employer of
        any of its rights under this Section 4.
 
             4.6.  Nonexclusivity and Survival.  The covenants and obligations
        of Executive contained in this Section 4 are in addition to, and not in
        lieu of, any covenants and obligations which Executive may have with
        respect to the subject matter hereof, whether by contract, as a matter
        of law or otherwise, and such covenants and obligations, and their
        enforceability, will survive any termination of Executive's employment
        by either party and any investigation made with respect to the breach
        thereof by Employer at any time.
 
          5.  Miscellaneous Provisions.
 
             5.1.  Severability.  If in any jurisdiction any term or provision
        hereof is determined to be invalid or unenforceable, (a) the remaining
        terms and provisions hereof shall be unimpaired, (b) any such invalidity
        or unenforceability in any jurisdiction shall not invalidate or render
        unenforceable such provision in any other jurisdiction, and (c) the
        invalid or unenforceable term or provision shall, for purposes of such
        jurisdiction, be deemed replaced by a term or provision that is valid
        and enforceable and that comes closest to expressing the intention of
        the invalid or unenforceable term or provision.
 
             5.2.  Execution in Counterparts.  This Agreement may be executed in
        one or more counterparts, and by the different parties hereto in
        separate counterparts, each of which shall be deemed to be an original
        but all of which taken together shall constitute one and the same
        agreement (and all signatures need not appear on any one counterpart),
        and this Agreement shall become effective when one or more counterparts

        affect the meaning or interpretation of any of the terms or provisions
        of this Agreement.
 
             5.8.  Binding Effect; Successors and Assigns.  Executive may not
        delegate her duties or assign her rights hereunder. This Agreement will
        inure to the benefit of, and be binding upon, the parties hereto and
        their respective heirs, legal representatives, successors and permitted
        assigns.
 
             5.9.  Waiver, etc.  The failure of either of the parties hereto to
        at any time enforce any of the provisions of this Agreement shall not be
        deemed or construed to be a waiver of any such provision, nor to in any
        way affect the validity of this Agreement or any provision hereof or the
        right of either of the parties hereto to thereafter enforce each and
        every provision of this Agreement. No waiver of any breach of any of the
        provisions of this Agreement shall be effective unless set forth in a
        written instrument executed by the party against whom or which
        enforcement of such waiver is sought, and no waiver of any such breach
        shall be construed or deemed to be a waiver of any other or subsequent
        breach.
 
             5.10.  Capacity, etc.  Executive and Employer hereby represent and
        warrant to the other that: (a) she or it has full power, authority and
        capacity to execute and deliver this Agreement, and to perform her or
        its obligations hereunder; (b) such execution, delivery and performance
        will not (and with the giving of notice or lapse of time or both would
        not) result in the breach of any agreements or other obligations to
        which she or it is a party or she or it is otherwise bound; and (c) this
        Agreement is her or its valid and binding obligation in accordance with
        its terms.
 
             5.11.  Enforcement.  If any party institutes legal action to
        enforce or interpret the terms and conditions of this Agreement, the
        prevailing party shall be awarded reasonable attorneys' fees at all
        trial and appellate levels, and the expenses and costs incurred by such
        prevailing party in connection therewith. Venue for any such action
        shall exclusively be Roanoke, Virginia.
 
           5.12.  Arbitration.
 
                (i) Any dispute under Section 3 hereof, including but not
           limited to the determination by the Board of a termination for Cause
           pursuant to Section 3.2.3 hereof or in respect of the breach thereof
           will be settled by arbitration in Roanoke, Virginia. The arbitration
           will be accomplished in the following manner. Either party may serve
           upon the other party written demand that the dispute, specifying the
           nature thereof, shall be submitted to arbitration. Within ten (10)
           days after the service of such demand, each of the parties will
           designate an arbitrator and serve written notice of such appointment
           upon the other party. If either party fails within the specified time
           to appoint such arbitrator, the other party will be entitled to
           appoint both arbitrators. The two (2) arbitrators so appointed will
           appoint a third arbitrator.
 
                (ii) The decision of the arbitrators will be final and binding
           upon the parties. The arbitration will be conducted, to the extent
           consistent with this Section 5.12, in accordance with the then
           prevailing rules of commercial arbitration of the American
           Arbitration Association or its successor.
 
             5.13.  Continuing Effect.  Where the context of this Agreement
        requires, the respective rights and obligations of the parties shall
        survive any termination or expiration of the term of this Agreement.
