     THIS AGREEMENT is effective as of June 1, 1996 between ELTRAX SYSTEMS,
INC., a Minnesota corporation (the "COMPANY"), and CLUNET R. LEWIS (the
"CONSULTANT").

     WHEREAS, the Consultant serves as a member of the Board of Directors of
the Company (the "BOARD"); and

     WHEREAS, the Company desires to engage the Consultant to perform certain
consulting services in order to benefit from the Consultant's management
experience and abilities, and the Consultant desires to accept such
engagement, all upon the terms and conditions set forth in this Agreement.

     NOW, THEREFORE, in consideration of the mutual promises contained
herein, the Company and the Consultant, each intending to be legally bound,
agree as follows:

     1. ENGAGEMENT. Subject to all of the terms and conditions of this
Agreement, the Company agrees to engage the Consultant (i) to assist the
Company in seeking out and identifying various opportunities for the Company
to increase its operations and revenues including, but not limited to,
possible acquisitions, joint ventures, marketing agreements and other growth
opportunities; (ii) to serve as Chief Financial Officer of the Company; and
(iii) to perform various management and other duties as may be agreed to from
time to time between the Board and the Consultant, and the Consultant agrees
to accept such engagement.

     2. DUTIES.

         a.  During the term of this Agreement, the Consultant agrees to consult
     with the Board and the Company regarding such matters, and to provide such
     services to the Board and the Company, as may reasonably be requested by
     the Board consistent with the Consultant's expertise and experience and the
     Consultant's position as Chief Financial Officer and a director of the
     Company and agreed to by the Consultant.

         b.  The services to be rendered by the Consultant to the Company
     pursuant to this Agreement will be as an independent contractor, and this
     Agreement does not make the Consultant an employee, agent or legal
     representative of the Company for any purpose whatsoever, including without
     limitation participation in any benefits or privileges given or extended by
     the Company to its employees.  No right or authority is granted to the
     Consultant to assume or create any obligation or responsibility, express
     or implied, on behalf of or in the name of the Company.  The Company will
     not withhold from the amounts paid to the Consultant under this Agreement
     for any federal or state taxes, and the Consultant agrees that he will pay
     all taxes due on such amounts paid.

         c.  Notwithstanding anything to the contrary contained in this
     Agreement other than in Section 7 hereof, nothing shall be construed to
     limit the ability of the Consultant to consult for or serve on the Board of
     Directors of such other corporations, trade associations, charitable
     organizations or other entities as the Consultant shall from time to time
     deem appropriate and to engage in such other activities as the Consultant
     shall reasonably deem not to be in conflict with his duties to the Company.

     3.  TERM. The term of this Agreement will commence on June 1, 1996 and,
subject to earlier termination in accordance with Section 4 below, will continue
for a period of one (1) year.  The term of this Agreement will automatically
renew for an additional one(1) year term unless earlier terminated in accordance
with Section 4 below.

     4. TERMINATION. Subject to the respective continuing obligations of the
Company and the Consultant under Sections 5(b), 6, 7 and 9 of this Agreement:

        a.  This Agreement may be terminated by the Company immediately upon
     written notice to the Consultant "for cause," with the basis for
     termination specified in such notice.  For purposes of this Agreement,

     embezzlement or material and deliberate injury or attempted injury, in
     each case related to the Company or its business, (ii) any unlawful or
     criminal activity of a serious nature, (iii) any willful breach of duty,

     disability plan of the Company then in effect for employees of the Company
     (regardless of whether the Consultant is covered by such plan) or, if no
     such plan exists, "Total Disability" will mean such disability that
     prevents the Consultant from performing his duties under Section 2 of this
     Agreement for a continuous period of ninety (90) days

        d.  This Agreement will be automatically terminated upon the death of
     the Consultant.

     5. COMPENSATION.

        a.  ANNUAL CONSULTING FEE. In consideration of the Consultant's services
     under this Agreement, the Company will pay the Consultant a fee as
     determined by the Company's Board of Directors or the Compensation
     Committee of such Board, payable in accordance with the Company's normal
     payroll practices commencing June 1, 1996.

        b.  EXPENSES. The Company will pay or reimburse the Consultant for
     reasonable expenses that the Consultant incurs while performing his duties
     under this Agreement, whether as a Consultant or as a director, provided
     that such expenses are incurred and properly accounted for in accordance
     with the Company's policies regarding reimbursement of business expenses as
     may be in effect from time to time.

     6. CONFIDENTIAL INFORMATION.

        a.  DEFINITION. "CONFIDENTIAL INFORMATION," as used in this Section 6,
     means information that is not generally known and that is proprietary to
     the Company or that the Company is obligated to treat as proprietary.
     This information includes, without limitation:

            (i)   trade secret or other proprietary information about the
        Company and its products; and


                                        2

<PAGE>

            (ii)   proprietary information concerning any of the Company's
         past, current, or possible future products, including (without
         limitation) proprietary information about the Company's research,
         development, engineering, purchasing, manufacturing, accounting,
         marketing, selling or leasing.

         Notwithstanding anything to the contrary contained herein, the term
"Confidential Information" does not include information which (i) is or becomes
available to the public other than as a result of a disclosure by the
Consultant, (ii) was within the Consultant's possession prior to its being
furnished to the Consultant by or on behalf of the Company pursuant to this
Agreement, or (iii) becomes available to the Consultant on a non-confidential
basis from a source other than the Company or its representatives.

         b. NONDISCLOSURE. The Consultant will not, either during or after his
     engagement  by the Company, use or disclose Confidential Information to
     any person not authorized by the Company to receive it, except (i) as
     required in the performance of the Consultant's duties to the Company,
     (ii) as required to enforce this Agreement, or (iii) as otherwise
     required by law.

         c. RETURN OF INFORMATION. When the Consultant's engagement with the
     Company ends, he will, upon the Company's request, promptly turn over to
     the Company all records and any compositions, articles, devices, apparatus
     and other items that disclose, describe or embody Confidential Information,
     including all copies, reproductions and specimens of the Confidential
     Information in his possession, regardless of who prepared them.

   7.    COMPETITIVE ACTIVITIES. The Consultant agrees that during the term of
this Agreement and for a period of two (2) years after termination of this
Agreement, regardless of the reason for such termination:

         a. He will not alone, or in any capacity with another firm:

            (i)   directly or indirectly compete with the Company's business, as
         the Company has conducted it during the Consultant's engagement with
         the Company, within any state in the United States or any country in
         which state or country the Company directly or indirectly markets or
         services products or provides services or reasonably plans or intends
         during Consultant's engagement period to market or service products or
         provide services;

            (ii)  solicit or encourage any Company customer or potential
         customer to cease to do business with or to not do business with the
         Company in such products; or

            (iii) employ or attempt to employ any of the Company's then
         employees on behalf of any other entity competing with the Company.

         b. The Consultant may, however, accept employment or service with an
     entity competing with the Company so long as the business of such entity
     is diversified, and the employment or service by the Consultant is with
     a separately managed and operated part of its business that does not
     compete with the Company.

     8.  NO ADEQUATE REMEDY. The Consultant understands that if he fails to
fulfill his obligations under this Agreement, the damages to the Company
would be very difficult to determine.  Therefore, in addition to any other
rights or remedies available to the Company at law, in equity or by statute, the


                                       3

Consultant hereby consents to the specific enforcement by the Company of
Sections 6 and 7 of this Agreement through an injunction or restraining order
issued by an appropriate court.

     9.  INDEMNIFICATION; DIRECTORS AND OFFICERS LIABILITY INSURANCE.

         a.   The Company shall pay or reimburse to the Consultant the fees and
     expenses of personal counsel for their professional services rendered to
     the Consultant in connection with this Agreement and any other agreement
     or benefit plan entered into or adopted in connection herewith and
     matters related hereto and thereto (PROVIDED; HOWEVER, that the fees and
     expenses of such counsel in connection with the execution and delivery
     of this Agreement shall not exceed $5,000), including in connection with
     any enforcement hereof and thereof if the Consultant is the prevailing
     party in any such dispute or enforcement action.  Without limiting the
     foregoing, in the event that the Company terminates, or seeks to
     terminate this Agreement, alleging as justification for such termination
     "for cause" as specified in Section 4 hereof and the Consultant in good
     faith disputes such termination or attempted termination, and the
     Company disputes its obligations pursuant to any provision of this
     Agreement, the Company shall pay, or reimburse to the Consultant, all
     reasonable costs incurred by the Consultant in such dispute, including
     attorneys' fees and costs, if the Consultant is the prevailing party in
     any such dispute or enforcement action.

         b. The Company shall indemnify and hold the Consultant harmless
     against all claims, damages, judgments, fines, amounts paid in
     settlement and reasonable expenses, including attorneys' fees and
     expenses, incurred by the Consultant:  (i) for any breach of any
     covenant of the Company contained herein, or in any agreement entered
     into in connection herewith, or (ii) in connection with the defense of,
     or as a result of any action or proceeding (or any appeal from any
     action or proceeding) (x) brought by the Company or any third party
     challenging the validity or enforceability of all or any portion of this
     Agreement and any other agreement entered into or adopted in connection
     herewith or (y) in which the Consultant is made or is threatened to be
     made a party by reason of the fact that the Consultant is or was an
     officer or director of the Company, regardless of when such action or
     proceeding may be brought and regardless of whether such action or
     proceeding is one brought by or in the right of the Company to procure a
     judgment in its favor (or other than by or in the right of the Company).
     The undertakings of subparagraph (a) are independent of and shall not be
     limited or prejudiced by the undertakings of this subparagraph (b).

         c.  In addition to the foregoing (and not in limitation):

            (i)   the Consultant will at all times be entitled to
         indemnification from the Company in accordance with Article V of the
         Amended and Restated Bylaws of the Company as in effect on the date
         hereof, the Consultant will be deemed to be an "Indemnified Person" as
         defined therein for all purposes, and the Consultant's rights
         thereunder will not be adversely affected by any subsequent amendment
         thereof; and

            (ii)  the Company will maintain in full force and effect one or
         more policies of directors and officers liability insurance providing
         for such coverage (in amounts not less than present amounts) as may be
         determined from time to time by the Board.

         d.  The provisions of this Section 9 shall survive the termination of
     this Agreement.
