$5,000,000.00                                                      June 23, 2000
                                                                Atlanta, Georgia

         FOR VALUE RECEIVED, the undersigned, ELTRAX SYSTEMS, INC., a Minnesota
corporation ("Maker"), promises to pay to the order of CEREUS TECHNOLOGY
PARTNERS, INC., a Delaware corporation (together with any permitted assignee,
the "Holder"), at Holder's principal offices located at 1000 Abernathy Road,
Suite 1000, Atlanta, Georgia 30328, or at such other address as Holder may from
time to time designate in writing, the principal sum of FIVE MILLION AND NO/100
DOLLARS ($5,000,000.00), or, if less, the unpaid aggregate principal amount of
all loans made from time to time hereunder, together with interest thereon as

                                       1
<PAGE>   2

amends and restates that certain $2,000,000.00 Non-Negotiable Subordinated
Convertible Promissory Note dated June 14, 2000 made by Maker in favor of
Holder.

         All capitalized terms used herein shall have the meanings ascribed to
such terms in that certain Bridge Loan and Security Agreement by and between
Maker (as Borrower thereunder) and Holder (as Lender thereunder) dated as of
June 14, 2000, as amended by Amendment No.1 thereto dated as of June 23, 2000,
as the same may be further amended (as so amended, the "Loan Agreement"), except
to the extent that such capitalized terms are otherwise defined or limited
herein.

         The aggregate then-current Loan Amount of the Loan loaned and borrowed
pursuant to the Loan Agreement shall be paid as provided in Section 2.1(d) of
the Loan Agreement.

         Maker may repay all or any portion of the Loan Amount outstanding
hereunder in full or in part at any time prior to the Maturity Date, without
penalty or premium, in the manner set forth in the Loan Agreement.

         All amounts of principal outstanding hereunder shall bear interest at a
rate equal to the Bridge Loan Interest Rate, which shall accrue and be payable
in accordance with the terms of Section 2.1 of the Loan Agreement. Unpaid
interest hereunder shall not bear interest. The entire principal balance hereof,
and all interest accrued and unpaid thereon, shall be due and payable in full on
the Maturity Date, except as otherwise set forth in Section 2.1(d) of the Loan
Agreement. The provisions of Article II of the Loan Agreement are hereby
incorporated herein by this reference.

         1. CONVERSION. Holder shall have the right, at Holder's option at any
time prior to or after the Maturity Date, to convert the then outstanding Loan
Amount in whole (but not in part) into that number of fully paid and
non-assessable shares of Borrower Common Stock determined by multiplying (i)
1.15 by (ii) a fraction, the numerator of which shall be the outstanding Loan
Amount on the date of conversion and the denominator of which shall be $7.5631
(the "Initial Conversion Price").

            1.1    CONVERSION PROCEDURE

                           1.1.1 Notice of Conversion. To effect the conversion
         of this Note into shares of Borrower Common Stock, Holder shall give
         written notice by hand or by overnight mail, or by mail, postage
         prepaid, to Maker at its address designated in Section 8 below, of the
         election to convert this Note pursuant to this Section 1.1. Holder
         shall surrender this Note contemporaneous with such notice. Such notice
         shall state therein the name or names (which shall be the names of the
         Holders) in which the certificate or certificates for shares of
         Borrower Common Stock are to be issued. Such conversion shall be deemed
         to have been made immediately prior to the close of business on the
         date

--------------------------
1        The Initial Conversion Price shall be the per share closing price for
the Borrower Common Stock on the day immediately prior to the date that Maker
and Holder publicly announce the transactions contemplated by the Merger
Agreement.

                                       2

<PAGE>   3

         (which shall be the date of conversion) on which Maker actually
         receives such notice and this Note, and the Person or Persons entitled
         to receive the shares of Borrower Common Stock issuable upon such
         conversion shall be treated for all purposes as the record holder or
         holders of such shares of Borrower Common Stock as of such date.

                           1.1.2 Delivery of Stock Certificate. As promptly as
         practicable after the date of conversion of this Note, but in no event
         later than five (5) Business Days after receipt thereof, Maker, at its
         expense, will issue and deliver to Holder a certificate or certificates
         for the number of full shares of Borrower Common Stock issuable upon
         such conversion.

                           1.1.3 Fractional Shares. No fractional shares of
         Borrower Common Stock shall be issued upon conversion of this Note. In
         lieu of Maker issuing any fractional shares to Holder upon the
         conversion of this Note, Maker shall issue a check payable to Holder
         for an amount equal to the fractional share times the Initial
         Conversion Price.

                           1.1.4 Transfer Taxes. Maker shall pay all taxes which
         may be payable in respect of the issuance of any shares of Borrower
         Common Stock deliverable upon conversion of this Note, except that
         Maker shall not be required to pay any tax imposed in connection with
         any transfer involving the issuance of a certificate for shares of
         Borrower Common Stock in any name other than that of the original
         Holder of this Note; and in such case, Maker shall not be required to
         deliver any certificate representing the shares of Borrower Common
         Stock purchased upon conversion until such tax shall have been paid, or
         it has been established to Maker's satisfaction that no tax is due.

                       1.2 ADJUSTMENTS. The number of shares of Borrower Common
Stock which may be received upon the conversion of this Note shall be subject to
change or adjustment from time to time as follows:

                           1.2.1 Stock Dividends; Stock Splits; Reverse Stock
         Splits; Reclassifications. In case Maker shall (i) pay a dividend or
         make any other distribution with respect to the Borrower Common Stock
         in shares of its capital stock, (ii) subdivide its outstanding Borrower
         Common Stock, (iii) combine its outstanding Borrower Common Stock into
         a smaller number of shares, or (iv) issue any shares of its capital
         stock in a reclassification of the Borrower Common Stock (including any
         such reclassification in connection with a merger (other than the
         transactions contemplated by the Merger Agreement), consolidation or
         other business combination in which Maker is the continuing
         corporation), then the number of shares of Borrower Common Stock
         issuable upon conversion of this Note (assuming it had been converted
         immediately prior to the record date for each such dividend or
         distribution or the effective date of each such subdivision or
         combination) shall be adjusted so that Holder shall thereafter be
         entitled after the completion of each such event to receive the kind
         and number of shares of Borrower Common Stock or other securities of
         Maker that Holder would have owned or have been entitled to receive
         after the happening of each such event had this Note been converted

                                       3
<PAGE>   4

         immediately prior to the happening of each such event or any record
         date with respect thereto. Each adjustment made pursuant to this
         Section 1.2.1 shall become effective immediately after the effective
         date of the applicable event retroactive to the record date, if any,
         for such event.

                           1.2.2 Rights; Options; Warrants. If the Merger
         Agreement shall be terminated pursuant to Section 8.1 thereof, and, at
         the time of such termination, Holder shall be entitled to receive a
         termination fee under Section 8.5 thereof, and if Maker shall at any
         time thereafter issue rights, options, warrants or convertible or
         exchangeable securities (other than a transaction subject to Section
         1.2.1 hereof) to all holders of the Borrower Common Stock, entitling
         them to subscribe for or purchase Borrower Common Stock at a price per
         share that is lower (at the record date for such issuance) than the
         Initial Conversion Price, then the number of shares of Borrower Common
         Stock thereafter issuable upon conversion of this Note shall be
         determined by adding the number of shares of Borrower Common Stock
         theretofore issuable upon conversion of this Note to the product of (a)
         the Cheap Stock Issued (as hereinafter defined), multiplied by (b) the
         Ownership Ratio (as hereinafter defined). Such adjustment shall be made
         whenever such rights, options, warrants or convertible or exchangeable
         securities are issued, and shall become effective retroactively
         immediately after the record date for the determination of shareholders
         entitled to receive such rights, options, warrants or convertible or
         exchangeable securities. For purposes of this Section 1.2.2, the term
         (x) "Cheap Stock Issued" shall be the number of additional shares of
         Borrower Common Stock offered by Maker for subscription or purchase as
         described above, minus the number of shares of Borrower Common Stock
         that the aggregate offering price of the total number of shares of
         Borrower Common Stock so offered would purchase at the Initial
         Conversion Price; and (y) "Ownership Ratio" shall be a fraction, the
         numerator of which shall be the number of shares of Borrower Common
         Stock theretofore issuable upon conversion of this Note, and the
         denominator of which shall be the shares of Borrower Common Stock
         outstanding immediately prior to the issuance of such rights, options,
         warrants or convertible or exchangeable securities, plus the number of
         shares of Borrower Common Stock theretofore issuable upon the
         conversion of this Note. Upon the expiration or termination of such
         rights, options, warrants or convertible or exchangeable securities the
         issuance of which triggered the adjustments referred to in this Section
         1.2.2 prior to any exercise thereof, the number of shares of Borrower
         Common Stock into which this Note shall be converted shall forthwith be
         readjusted to the number of shares of Borrower Common Stock that would
         have been issuable had such expired or terminated rights, options,
         warrants or convertible or exchangeable securities not been issued by
         Maker.

                           1.2.3 Distributions of Debt, Assets, Subscription
         Rights or Convertible Securities. In case Maker shall fix a record date
         for the making of a distribution to all holders of shares of the
         Borrower Common Stock of evidences of indebtedness of Maker, assets
         (other than cash dividends payable out of retained earnings or
         securities (excluding those referred to in Sections 1.2.1 and 1.2.2
         hereof) (any such evidences of indebtedness, assets, or securities
         being referred to in this Section 1.2.3 as the "assets or securities"),
         then in each case Holder, upon the conversion of this Note, shall be
         entitled to receive in

                                       4

<PAGE>   5

         addition to the shares of Borrower Common Stock issuable upon
         conversion of this Note, (a) the assets or securities to which Holder
         would have been entitled as a holder of Borrower Common Stock if Holder
         had converted this Note immediately prior to the record date for such
         distribution, and (b) any interest or distributions on the assets or
         securities distributed from the distribution date to the date of
         exercise. At the time of any such distribution, Maker shall either (x)
         deposit the assets or securities payable to Holder pursuant hereto in
         trust for Holder with an eligible institution (as hereinafter defined)
         with instructions as to the investment of such property and any
         proceeds therefrom so as to protect the value of such property for
         Holder, or (y) distribute to Holder the assets or securities to which
         it would be entitled upon exercise and, upon any such distribution
         pursuant to this clause (y), the provisions of this Section 1.2.3 shall
         no longer apply to such event. Such election shall be made by Maker by
         giving written notice thereof to Holder. For purposes of this Section
         1.2.3, the term "eligible institution" shall mean a corporation
         organized and doing business under the laws of the United States of
         America or of any state thereof, authorized under such laws to exercise
         corporate trust powers, having a combined capital and surplus of at
         least $100,000,000, and subject to supervision or examination by
         Federal or state authority.

                           1.2.4 Reclassification, Reorganization, Consolidation
         or Merger. In the event of any reclassification, capital reorganization
         or other change of outstanding shares of Borrower Common Stock of Maker
         (other than a subdivision or combination of the outstanding Common
         Stock, a change in the par value of the Common Stock or a transaction
         subject to Sections 1.2.1, 1.2.2 or 1.2.3 hereof) or in the event of
         any consolidation or merger of Maker with or into another corporation
         (other than the transactions contemplated by the Merger Agreement, a
         merger in which Maker is the continuing corporation and that does not
         result in any reclassification, capital reorganization or other change
         of outstanding shares of Borrower Common Stock of the class issuable
         upon conversion of this Note or a transaction subject to Sections
         1.2.1, 1.2.2 or 1.2.3 hereof) or in the event of any sale, lease,
         transfer or conveyance to another corporation of the property and
         assets of Maker as an entirety or substantially as an entirety, in each
         case as a result of which the holders of Borrower Common Stock shall be
         entitled to receive stock, securities or other property or assets
         (including cash) with respect to or in exchange for such Borrower
         Common Stock, then Maker shall, as a condition precedent to such
         transaction, cause effective provisions to be made so that such other
         corporation shall assume all of the obligations of Maker hereunder, and
         Holder shall have the right thereafter, by converting this Note, to
         receive the kind and amount of shares of stock and other securities and
         property (including cash) receivable upon such reclassification,
         capital reorganization and other change, consolidation, merger, sale,
         lease, transfer or conveyance by a holder of the number of shares of
         Borrower Common Stock that might have been received upon conversion of
         this Note immediately prior to such reclassification, capital
         reorganization, change, consolidation, merger, sale, lease or
         conveyance. Any such provision shall include provision for adjustments
         in respect of such shares of stock and other securities and property
         that shall be as nearly equivalent as may be practicable to the
         adjustments provided for in this Note. The foregoing provisions of

                                       5

<PAGE>   6

         this Section 1.2.4 shall similarly apply to successive
         reclassifications, capital reorganizations and changes of shares of
         Borrower Common Stock and to successive changes, consolidations,
         mergers, sales, leases, transfers or conveyances of the nature and type
         described in the first sentence hereof. In the event that in connection
         with any such capital reorganization, reclassification, consolidation,
         merger, sale, lease, transfer or conveyance, additional shares of
         Borrower Common Stock shall be issued in exchange, conversion,
         substitution or payment, as a whole or in part, for, or of, a security
         of Maker other than Borrower Common Stock, any such issue shall be
         treated as an issue of Borrower Common Stock covered by the provisions
         of Section 1.2.1 hereof.

                           1.2.5 De Minimis Adjustments. Except as provided in
         Section 1.2.6 hereof with reference to adjustments required by such
         Section 1.2.6, no adjustment in the number of shares of Borrower Common
         Stock issuable hereunder shall be required unless such adjustment would
         require an increase or decrease of at least one percent (1%) in the
         number of shares of Borrower Common Stock issuable upon the conversion
         of this Note; provided, however, that any adjustments which by reason
         of this Section 1.2.5 are not required to be made shall be carried
         forward and taken into account in any subsequent adjustment. All
         calculations shall be made to the nearest one-thousandth of a share.

                           1.2.6 Adjustments. In case Maker after the date
         hereof shall take any action affecting the shares of Borrower Common
         Stock into which this Note may be converted, other than any action
         described in Sections 1.2.1, 1.2.2, 1.2.3 or 1.2.4 hereof, which
         Maker's Board of Directors, acting in the good faith exercise of its
         reasonable judgment, determines would have a material adverse effect on
         the rights of Holder, then the conversion price, the number of shares
         of Borrower Common Stock into which this Note may be converted and/or
         the character of the securities receivable upon conversion of this Note
         may be adjusted in such manner, if any, and at such time, by action of
         the directors, acting in the good faith exercise of their reasonable
         judgment, subject to obtaining all necessary approvals to such
         adjustment, including, without limitation, any necessary approvals of
         any stock exchange or over-the-counter market on which securities of
         Maker are then listed or quoted.

                           1.2.7 Notice of Adjustment. Whenever the number of
         shares of Borrower Common Stock or other stock or property issuable
         upon the conversion of this Note is adjusted, as herein provided, Maker
         shall promptly notify Holder of such adjustment or adjustments.

                 1.3       CONVERSION SHARES SUBJECT TO REGISTRATION RIGHTS.
Maker and Holder agree that the shares of Borrower Common Stock and other
securities (as the case may be) receivable upon the conversion of this Note
shall be "Registrable Stock" as defined in that certain Amended and Restated
Registration Rights Agreement between the Company and the Holder dated as of
June 23, 2000 and shall be subject to the terms and conditions thereof.

         2.      NOTICES OF RECORD DATE, ETC. In the event of (a) any taking by
Maker of a record of the holders of any class of securities of Maker for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend payable out of earned

                                       6

<PAGE>   7

surplus at the same rate as that of the last such cash dividend theretofore
paid) or other distribution, or any right to subscribe for, purchase or
otherwise acquire any shares of stock of any class or any other securities or
property, or to receive any other right; (b) any capital reorganization of
Maker, any reclassification or recapitalization of the capital stock of Maker or
any transfer of all or substantially all of the assets of Maker to any other
person or any consolidation or any merger involving Maker (other than the
transactions contemplated by the Merger Agreement); or (c) any voluntary or
involuntary dissolution, liquidation or winding-up of Maker, Maker will, but
only to the extent that such information is disclosed to Maker's shareholders,
and then contemporaneous therewith, mail to Holder a notice specifying (x) the
date on which any such record is to be taken for the purpose of such dividend,
distribution or right, and the amount and character of such dividend,
distribution or right; and (y) the date on which any such reorganization,
reclassification, transfer, consolidation, merger, dissolution, liquidation or
winding-up is expected to become effective and the record date for determining
shareholders entitled to vote thereon.

         3. SHARES RESERVED FOR ISSUANCE. Maker shall at all times reserve and
keep available out of its authorized but unissued shares of Borrower Common
Stock solely for the purpose of effecting the conversion of this Note such
number of shares of Borrower Common Stock as shall from time to time be
sufficient to effect the conversion of this Note; and if at any time the number
of authorized but unissued shares of Borrower Common Stock shall not be
sufficient to effect the conversion of the entire outstanding principal amount
of this Note, in addition to such other remedies as shall be available to the
Holder of this Note, Maker will use its best efforts to take such corporate
actions as may be necessary to increase its authorized but unissued shares of
Borrower Common Stock to such number of shares as shall be sufficient for such
purposes.

         4. EVENTS OF DEFAULT. If an Event of Default occurs and is continuing,
then, at Holder's option, Holder may (subject to the terms of the Subordination
Agreement) declare the entire principal amount outstanding hereunder, together
with all accrued and unpaid interest thereon, immediately due and payable and
pursue such remedies as are provided in the Loan Agreement. The rights,
remedies, powers and privileges provided for herein are cumulative and not
exclusive of any rights, remedies, powers and privileges provided by law.

        5. SUBORDINATION. Maker and Holder each acknowledges and agrees that the
payment of the principal and interest (including, without limitation,
post-petition interest, whether or not a claim for such post-petition interest
is allowed in the related bankruptcy proceeding) hereunder and any and all other
obligations and liabilities now or at any time or times hereafter owing by Maker
or any subsidiary of Maker to Holder or any other person under or in respect of,
and all of Holder's rights under or in respect of, this Note and any amendments,
modifications, extensions, renewals, refinancings and replacements hereof
(including, without limitation, obligations and liabilities in respect of
expenses, costs, indemnities, conversions, redemptions and special contingent
payments), together with any and all guaranties, collateral and other security,
if any, for the payment thereof, are subordinated in all respects pursuant to,
and are subject to, the terms of the Subordination Agreement.

2. CONSENTS TO LIENS. Senior Creditor hereby consents to Eltrax's grant of Liens
in the Collateral to Junior Creditor as security for the Junior Creditor
Obligations and agrees that the existence of any such Liens (other than any Lien
that may hereafter arise from any judgment obtained against Eltrax or any other
Borrower) shall not constitute an Event of Default under any of the Senior
Creditor Documents. Junior Creditor hereby acknowledges Eltrax's (and each other
Borrower's) grant of Liens in the Collateral to Agent as security for the Senior
Creditor Obligations and agrees that the existence of any such Liens shall not
constitute an Event of Default under any of the Junior Creditor Documents.

3. PRIORITY OF LIENS.

                  (a) Junior Creditor and Agent agree at all times, whether
before, after or during the pendency of any Bankruptcy Case or other insolvency
proceeding and notwithstanding the priorities which would ordinarily result from
the order of granting or perfection of any Liens, the order of filing or
recording of any financing statements, or the priorities that would otherwise
apply under applicable law, that (i) Agent's Liens in the Collateral shall
constitute first priority Liens in such property to secure the Senior Creditor
Obligations and shall be superior to any Lien or other interest of Junior
Creditor in the same property arising pursuant to the Junior Creditor Documents,
by operation of law or otherwise; and (ii) any Lien or other interest at any
time acquired by Junior Creditor in any of the Collateral shall be subordinate
to the Liens of Agent therein.

                  (b) If for any reason any Lien granted or conveyed by Eltrax
or any other Borrower to Agent pursuant to the Senior Creditor Documents or
otherwise is set aside or otherwise declared ineffective, in whole or in part,
by any court of competent jurisdiction, and if as a consequence thereof Junior
Creditor becomes entitled to receive any proceeds from any of the Collateral or
on account of such Junior Creditor's Lien in any of the Collateral, then any
such payments or proceeds received by such Junior Creditor shall be used by it
to purchase a junior participation in the Senior Creditor Obligations pursuant
to a junior participation agreement in form and content satisfactory to Agent
but in all events

<PAGE>   5

providing that Agent's retained interest in the Senior Creditor Obligations
(including both principal and interest) and all costs and expenses incurred by
Senior Creditor (including attorneys' fees) in attempting to collect the Senior
Creditor Obligations or to realize upon any of the Collateral shall be paid in
full before such Junior Creditor shall be entitled to any payment on account of
its junior participation and such Junior Creditor's junior participation will be
without recourse of any kind to Agent except for Agent's gross negligence or
willful misconduct after the date of such Junior Creditor's purchase of such
junior participation.

                  (c) In no event shall Junior Creditor institute, or join as a
party in the institution of, or directly or indirectly assist in the prosecution
of, any action, suit or proceeding seeking a determination that the Lien of
Agent in any of the Collateral is invalid, unperfected or avoidable, or is or
should be subordinated to the interests of any other Person. In no event shall
Agent or any Senior Creditor institute, or join as a party in the institution
of, or directly or indirectly assist in the prosecution of, any action, suit or
proceeding seeking a determination that the Lien of Junior Creditor in any of
the Collateral is invalid, unperfected or avoidable, or is or should be
subordinated to the interests of any other Person other than Agent under the
terms hereof.

                  (d) If, at any time, Agent shall subordinate in whole or in
part its Lien upon any of the Collateral to or in favor of any other Person, the
priority of Agent's Lien in the Collateral vis-a-vis Junior Creditor shall not
be affected thereby, and Agent's Lien shall continue to be superior to Junior
Creditor's Lien in the Collateral as provided in paragraph 3(a) of this
Agreement.

4. DEBT SUBORDINATION/PERMITTED PAYMENTS.

                  (a) Subject to the provisions of paragraph 4(c) and 4(d)
hereof relating to payments on the Junior Creditor Obligations that are
permitted to be made to the extent and under the circumstances set forth in
paragraphs 4(c) and 4(d), Junior Creditor hereby postpones and subordinates all
of the Junior Creditor Obligations to the full and final payment and discharge
of all of the Senior Creditor Obligations.

                  (b) In the event of any distribution (other than a
distribution of Reorganization Securities), division or application, partial or
complete, voluntary or involuntary, by operation of law or otherwise, of all or
any part of the assets of Eltrax or any other Borrower or the proceeds thereof
to Junior Creditor or upon any indebtedness of Eltrax or any other Borrower, by
reason of the liquidation, dissolution or other winding up of Eltrax or such
Borrower or Eltrax's or such Borrower's business, or in the event of any sale,
receivership, insolvency or bankruptcy proceeding, or assignment for the benefit
of creditor, or any proceeding by or against Eltrax or any other Borrower for
any relief under the Bankruptcy Code or other insolvency law relating to the
relief of debtors, readjustment of indebtedness, reorganization, compositions or
extensions, then and in any such event any payment or distribution of any kind
or character, whether in cash, securities or other property (excluding
Reorganization Securities), which shall be payable or deliverable upon or with
respect to any of the Junior Creditor Obligations shall be paid or delivered
directly to Agent for application to the Senior Creditor Obligations (whether or
not the same is then due) until all of the Senior Creditor Obligations has been
fully paid and discharged. The Subordinated Note shall at all times bear a
conspicuous legend that the Junior Creditor Obligations evidenced thereby are
subordinated to the Senior Creditor Obligations pursuant to this Agreement.
Eltrax's and Junior Creditor's books shall be marked to evidence the
subordination of all of the Junior Creditor Obligations to the Senior Creditor
Obligations. Agent is authorized to examine such books from time to time and to
make any notations required by this Agreement. The provisions of this paragraph
4 shall remain effective and binding upon Junior Creditor, to the full extent of
the Senior

<PAGE>   6

Creditor Obligations, even if any of the Senior Creditor Obligations is avoided,
equitably subordinated or nullified in any Bankruptcy Case of Eltrax or any
other Borrower.

                  (c) Eltrax may pay to Junior Creditor, and Junior Creditor may
accept and retain, the regularly scheduled installment of interest due and owing
to Junior Creditor from Eltrax on September 30, 2000 under the Subordinated Loan
Agreement and Subordinated Note in accordance with their present tenor, but
without prepayment, whether mandatory or optional, or payment upon acceleration.

                  (d) For so long as (i) no Event of Default exists under any of
the Senior Creditor Documents or would exist as a result of any payment on
account of the Subordinated Note and (ii) Undrawn Availability at the time of
and after giving effect to any payment on account of the Subordinated Note is
not less than the amount required by Section 6.10 of the Credit Agreement, and
except as otherwise provided in paragraph 4(b) hereof, Eltrax may pay to Junior
Creditor, and Junior Creditor may accept and retain, any regularly scheduled
installments of interest due and owing to Junior Creditor from Eltrax under the
Subordinated Loan Agreement and Subordinated Note in accordance with their
present tenor, but without prepayment, whether mandatory or optional, or payment
upon acceleration. If an Event of Default under any of the Senior Creditor
Documents exists or would result from the making of any payment under the
Subordinated Loan Agreement or the Subordinated Note, Eltrax shall not be
permitted to make, and Junior Creditor shall be entitled to accept or retain,
any payments on the Subordinated Note. In no event shall Senior Creditors'
continuing to honor any requests of Eltrax or any other Borrower for Advances
under the Credit Agreement after the occurrence or existence of any Event of
Default under the Senior Creditor Documents be deemed a waiver thereof, unless
such Event of Default is expressly waived in writing by Senior Creditors.

5. WARRANTIES AND REPRESENTATIONS OF ELTRAX AND JUNIOR CREDITOR. Eltrax and
Junior Creditor each hereby represents and warrants (severally and not jointly)
that: (i) it has not relied nor will it rely on any representation or
information of any nature made by or received from Agent or any Senior Creditor
relative to Eltrax or any other Borrower in deciding to execute this Agreement;
(ii) no part of the Junior Creditor Obligations is evidenced by any instrument
or writing except the Subordinated Loan Agreement and Subordinated Note and the
other documents contemplated therein; (iii) Junior Creditor is the lawful owner
of the Junior Creditor Obligations; (iv) Junior Creditor has not heretofore
assigned or transferred any of the Junior Creditor Obligations, any interest
therein or any Collateral or security pertaining thereto; and (v) Junior
Creditor has not heretofore given any subordination in respect of the Junior
Creditor Obligations.

6. NEGATIVE COVENANTS. For so long as this Agreement is in effect: (i) neither
Eltrax nor any other Borrower shall, directly or indirectly, make any payment
(other than a payment permitted by paragraph 4 hereof) on account of the Junior
Creditor Obligations; (ii) Junior Creditor shall not demand, collect or accept
from Eltrax or any other Person, including any other Borrower, any payment
(other than a payment permitted by paragraph 4 hereof) on account of the Junior
Creditor Obligations or any part thereof, or accelerate the maturity of any of
the Junior Creditor Obligations or realize upon or enforce any security
heretofore granted by any Person, including any other Borrower, as collateral
for any of the Junior Creditor Obligations; (iii) Junior Creditor shall not
exchange, set off, release, convert to equity or otherwise discharge any part of
the Junior Creditor Obligations, except as contemplated by the Junior Creditor
Documents as in existence on the date hereof; (iv) Junior Creditor shall not
hereafter give any subordination in respect of the Junior Creditor Obligations
or transfer or assign any of the Junior Creditor Obligations to any Person other
than Agent unless the transferee or

<PAGE>   7

assignee thereof first agrees in writing with Agent to be bound by the terms of
this Agreement; (v) no Borrower shall hereafter issue any instrument, security
or other writing evidencing any part of the Junior Creditor Obligations, and
Junior Creditor will not receive any such writing, except upon the prior written
approval of Agent or at the request of and in the manner requested by Agent;
(vi) Eltrax and Junior Creditor shall not amend, alter or modify any provision
of the Subordinated Loan Agreement or the Subordinated Note without the prior
written consent of Agent (other than to reduce the rate of interest or extend
the time for payment); (vii) Junior Creditor shall not commence or join with any
other creditor of Eltrax or any other Borrower in commencing any Bankruptcy Case
or reorganization, receivership or insolvency proceeding against Eltrax or any
other Borrower; and (viii) none of Eltrax, any other Borrower or Junior Creditor
otherwise shall take or permit any action prejudicial to or inconsistent with
Agent's priority position over Junior Creditor that is created by this
Agreement.

7. STANDBY AS TO CERTAIN ACTIONS. Junior Creditor agrees that it will not ask
for, demand, sue for, take, receive, or repossess any of the Collateral from
Eltrax or any other Borrower by setoff or in any other manner, or otherwise take
any Enforcement Action to collect any of the Junior Creditor Obligations or to
realize upon the whole or any part of the Collateral, whether by judicial action
or under power of sale, by self-help repossession or otherwise, unless and until
all of the Senior Creditor Obligations have been paid finally and in full. If
Junior Creditor, in violation hereof, initiates any Enforcement Action against
Eltrax or any other Borrower or any of the Collateral, Eltrax or such other
Borrower may interpose this Agreement as a complete defense, and Agent may
intervene and interpose this Agreement as a defense in Agent's name or in the
name of Eltrax or such other Borrower.

8. SENIOR CREDITOR'S RIGHTS EXCLUSIVE. Agent shall have the exclusive right to
collect, foreclose upon, sell, transfer, liquidate or otherwise dispose of the
Collateral as provided in the Senior Creditor Documents or by applicable law, in
the manner deemed appropriate by Agent, without regard to any Liens of Junior
Creditor therein, and Junior Creditor will not hinder Agent's actions in
enforcing its remedies or taking any Enforcement Action with respect to the
Collateral; provided, however, that after payment in full of all Senior Creditor
Obligations, Agent shall deliver to Junior Creditor (unless otherwise restricted
by law or by any order issued by a court in the proper exercise of its
jurisdiction and subject in all events to Agent's receipt of an indemnification
from Junior Creditor of all liabilities arising from such delivery) for
application to the Junior Creditor Obligations any proceeds remaining from the
sale or other disposition of the Collateral. To the fullest extent permitted by
applicable law, Junior Creditor waives any requirement on the part of Agent to
conduct any sale or other disposition of any of the Collateral in a commercially
reasonable manner, and Agent shall be fully authorized to sell or otherwise
dispose of any or all of the Collateral in the manner deemed appropriate by
Agent, including by the exercise of any right Agent may have to accept any or
all of the Collateral in total or partial satisfaction of any of the Senior
Creditor Obligations in accordance with the Code or otherwise.

9. RECEIPT OF MONIES BY JUNIOR CREDITOR. Junior Creditor agrees that should it
receive at any time prior to payment in full of all Senior Creditor Obligations
any payment, distribution or security (other than Reorganization Securities)
from Eltrax or any other Borrower in violation of this Agreement or any money
from the sale, liquidation, casualty or other disposition of, or as a result of
Junior Creditor's Lien in any of the Collateral, it will (unless otherwise
restricted by law) hold the same in trust for Agent and promptly pay over the
same to Agent for application to the Senior Creditor Obligations (unless
otherwise restricted by law or by any order issued by a court in the proper
exercise of its jurisdiction).

10. AGREEMENT ON CERTAIN BANKRUPTCY MATTERS.

                  (a) Without impairing, abrogating or in any way affecting
Agent's rights hereunder, including the relative priorities established by
paragraph 3 hereof, Agent may during any Bankruptcy Case give or withhold its
consent to Eltrax's, any other Borrower's or any bankruptcy trustee's use of any
Collateral (including cash proceeds of any Collateral) or may provide financing
or otherwise extend credit to Eltrax, any other Borrower or any bankruptcy
trustee secured by a Lien upon any or all of the Collateral whether created,
acquired or arising prior to or after the commencement of any such Bankruptcy
Case, and by its execution of this Agreement Junior Creditor shall be deemed to
have consented to Eltrax's, any other Borrower's or any bankruptcy trustee's use
of Collateral if and to the extent consented to by Agent and to any financing
proposed to be provided by Senior Creditors to any Borrower or any bankruptcy
trustee during the pendency of any such Bankruptcy Case. Any Lien at any time
granted to or otherwise acquired by Junior Creditor in any of the Collateral,
whether such Collateral is created, acquired or arises prior to or after the
commencement of any such Bankruptcy Case, shall be subject to all of the terms
of this Agreement and shall be subordinate in priority to all Liens granted to
or otherwise obtained by Agent with respect to any such Collateral, including
Liens granted to or conferred upon Agent or any Senior Creditors to secure
financings in any such Bankruptcy Case.

                  (b) If Agent consents to the sale of any of the Collateral
during any Bankruptcy Case (whether such sale is to be made pursuant to 11
U.S.C. ss. 363, pursuant to a plan of reorganization or otherwise), then Junior
Creditor shall be deemed to have consented to any such sale and shall, if
requested to do so by Agent in connection with any such sale Junior Creditor
shall promptly execute and deliver to Agent a release of Junior Creditor's Liens
with respect to the Collateral to be sold.

                  (c) If, in or as a result of any Bankruptcy Case, Agent
returns, refunds or repays to Eltrax, any other Borrower or any trustee or
committee appointed in the Bankruptcy Case any payment or proceeds of any
Collateral in connection with any action, suit or proceeding alleging that
Agent's receipt of such payments or proceeds was a transfer voidable under state
or federal law, then Agent shall not be deemed ever to have received such
proceeds for purposes of this Agreement in determining whether and when all of
the Senior Creditor Obligations have been paid in full.

                  (d) If Junior Creditor has any claim against Eltrax or any
other Borrower in any Bankruptcy Case, assignment for the benefit of Junior
Creditor, receivership proceedings, dissolution proceedings or similar
proceedings, Junior Creditor hereby makes, constitutes and appoint Agent as
Junior Creditor's attorney-in-fact and authorizes Agent to file, in the name of
Junior Creditor, such claim on behalf of Junior Creditor and any sums received
by Agent in connection with such claim shall be applied to the Senior Creditor
Obligations to the extent thereof. Agent shall remit to Junior Creditor any
funds remaining after those sums have been so applied, to the extent permitted
by applicable laws or the proceedings governing any such bankruptcy.

11. SUBROGATION. Provided that the Senior Creditor Obligations have been
indefeasibly paid and discharged and the Senior Creditor Documents have been
terminated, Junior Creditor shall be subrogated (without any representation by
or recourse to any Senior Creditor) to the rights of Senior Creditors to receive
payments or distributions of cash, property or securities payable or
distributable on account of the Senior Creditor Obligations, to the extent of
all payments and distributions paid over to or for the benefit of Senior
Creditors pursuant to this Agreement on account of the Junior Creditor
Obligations. In no event, however, shall Junior Creditor have any rights or
claims against any Senior Creditor for any alleged impairment of Junior
Creditor's subrogation rights,

<PAGE>   9

Junior Creditor acknowledging that any actions taken by any Senior Creditor with
respect to the Senior Creditor Obligations or the Collateral are authorized and
consented to by Junior Creditor.

12. AGREEMENT TO RELEASE LIENS. Junior Creditor agrees that it will (if
requested to do so by Agent after and during the continuance of an Event of
Default under the Senior Creditor Documents) release its Liens, if any, in any
Collateral in connection with and in order to facilitate any orderly liquidation
sale of such Collateral by Eltrax or any other Borrower or any bankruptcy
trustee or receiver for any Borrower, and promptly upon the request of Agent, it
will execute and deliver such documents, instruments and agreements as are
necessary to effectuate such release and to evidence such release in the
appropriate public records. Notwithstanding the foregoing, the Lien, if any,
granted to Junior Creditor shall, subject to all of the provisions of this
Agreement, continue in the proceeds of any such Collateral if such proceeds are
not applied to the Senior Creditor Obligations in accordance with the terms of
the Senior Creditor Documents.

13. WAIVER OF MARSHALING; APPLICATION OF PAYMENTS AND PROCEEDS. Junior Creditor
hereby waives any right to require Agent or any Senior Creditor to marshall any
security or collateral or otherwise to compel Agent or any Senior Creditor to
seek recourse against or satisfaction of the indebtedness to it from one source
before seeking recourse or satisfaction from another source. Agent shall be
authorized to apply any and all payments, collections and proceeds of Collateral
received by it to such portion of the Senior Creditor Obligations as Agent may
lawfully elect consistent with the provisions of the Senior Creditor Documents.

14. PROVISIONS CONCERNING INSURANCE. Proceeds of the Collateral include
insurance proceeds, and therefore the priorities set forth in paragraph 3 hereof
govern the ultimate disposition of casualty insurance proceeds. Agent shall have
the sole and exclusive right, as against Junior Creditor, to adjust settlement
of insurance claims in the event of any covered loss, theft or destruction of
the Collateral. All proceeds of such insurance shall inure to Agent to the
extent of the Senior Creditor Obligations, and Junior Creditor shall cooperate
(if necessary), at Agent's expense, in a reasonable manner in effecting the
payment of insurance proceeds to Agent. Agent shall have the right (as set forth
in the Senior Creditor Documents) to determine whether such proceeds will be
applied to its claim or used to rebuild, replace or repair the affected
Collateral. If such proceeds are applied to Senior Creditor Obligations, any
proceeds remaining after payment of Senior Creditor Obligations and all expenses
of collection shall be promptly remitted to Junior Creditor for application to
the Junior Creditor Obligations or to Eltrax, as applicable.

15. NOTICES. All notices, requests and demands to or upon a party hereto shall
be in writing and shall be delivered by hand, sent by certified or registered
mail, return receipt requested or by telecopier and shall be deemed to have been
validly served, given or delivered when delivered against receipt or three (3)

or to such other address as each party may designate for itself by like notice
given in accordance with this paragraph. Any written notice that is not sent in
conformity with the provisions hereof shall nevertheless be effective on the
date that such notice is actually received by the noticed party. Junior Creditor
hereby agrees that any requirement for the giving of notice by Agent under the
Code or otherwise in connection with any exercise by Agent of any of its rights
or remedies with respect to the Collateral shall be satisfied by the giving of
written notice at least five (5) days prior to the date on which such rights or
remedies are to be exercised by Agent, provided that nothing herein shall be
deemed to require the giving of any such notice when such notice is not required
by applicable law.

16. AUTHORITY. Agent hereby represents and warrants to Junior Creditor and
Eltrax that Agent has the right power and authority to execute this Agreement on
behalf of itself and each Senior Creditor and that upon the execution of this
Agreement by Agent, Agent and each Senior Creditor will be bound by the terms
hereof. Junior Creditor hereby represents and warrants to Agent, that Junior
Creditor has the right power and authority to execute this Agreement on behalf
of itself and each Junior

<PAGE>   11

Creditor and that upon the execution of this Agreement by Junior Creditor,
Junior Creditor will be bound by the terms hereof.

17. NO DUTIES IMPOSED UPON SENIOR CREDITOR. The rights granted to Agent in this
Agreement are solely for its protection and nothing herein contained imposes on
Agent any duties with respect to any of the Collateral. Agent has no duty to
preserve rights against prior parties on any instrument or chattel paper
received from Eltrax or any other Borrower as collateral security for any of the
Senior Creditor Obligations.

18. SPECIFIC ENFORCEMENT. If Junior Creditor fails to comply with any provision
of this Agreement that is applicable to it, Agent may demand specific
performance of this Agreement and may exercise any other remedy available at law
or equity.

19. ADDITIONAL CREDIT EXTENSIONS. Junior Creditor acknowledges, understands and
agrees that Senior Creditors may make Advances to Eltrax and the other Borrowers
from time to time, pursuant to the Senior Creditor Documents or otherwise, and
all such Advances shall constitute part of the Senior Creditor Obligations and
shall be secured by all of the Collateral, and nothing herein shall restrict in
any manner or in any way the right of any Borrower to obtain additional credit
from Senior Creditors or the right of any Senior Creditors to make available
such additional credit to any Borrower as Senior Creditors in their sole
discretion may elect.

20. INDEMNITY. Junior Creditor agrees to indemnify, defend and hold Agent and
each Senior Creditor harmless from and against any loss, damage, cost, claim or
expense, including court costs and attorneys' fees, incurred or sustained by
Agent or any Senior Creditor in connection with any remittances of proceeds of
any Collateral made pursuant to the terms hereof from Agent to Junior Creditor,
to the extent that such remittance of proceeds subsequently is determined by a
court of competent jurisdiction to have been prohibited by applicable law,
avoidable under any insolvency law (including the Bankruptcy Code), or in
violation of the rights of any other creditor of any Borrower when made. The
foregoing indemnity shall survive any termination of this Agreement.

21. INDEPENDENT CREDIT INVESTIGATIONS. None of the parties hereto nor any of
their respective directors, officers, agents, employees, successors or assigns
shall be responsible to the others or to any other Person for any Borrower's
solvency, financial condition or ability to repay any of the Junior Creditor
Obligations or any of the Senior Creditor Obligations, or for statements of any
Borrower, oral or written, or for the validity, sufficiency or enforceability of
any of the Junior Creditor Documents or any of the Senior Creditor Documents, or
the validity or priority of any Liens granted by any Borrower to either party in
connection with any of the Junior Creditor Documents or any of the Senior
Creditor Documents. Each party hereto has entered into its agreements with
Eltrax and the other Borrowers based upon its own independent investigation, and
makes no warranty or representation to the other party nor does it rely upon any
representation of the other party with respect to matters identified or referred
to in this paragraph.

22. NO ADDITIONAL RIGHTS OF BORROWERS HEREUNDER. Nothing herein shall be
construed to confer additional rights upon Eltrax or any other Borrower. Without
limiting the generality of the foregoing, if any party hereto shall enforce its
rights or remedies in violation of this Agreement, no Borrower shall be
authorized to use such violation as a defense to any right or remedy exercised
by such party, nor assert such violation as a counterclaim or basis of setoff or
recoupment against such party,

<PAGE>   12

unless the other party hereto consents in writing and itself asserts that the
exercise of right or remedy is in violation of this Agreement.

23. TERM OF AGREEMENT. This Agreement shall continue in full force and effect
and shall be irrevocable by any party hereto until the earliest to occur of the
following: (i) the parties hereto in writing mutually agree to terminate this
Agreement; (ii) the Junior Creditor Obligations are fully paid and discharged
and the Junior Creditor Documents are terminated; or (iii) the Senior Creditor
Obligations are fully paid and discharged and the Senior Creditor Documents are
terminated.

24. GOVERNING LAW. This Agreement shall be interpreted, and the rights and
obligations of the parties hereto determined, in accordance with the internal
laws of the State of Georgia.

25. NO THIRD PARTY BENEFICIARIES. Nothing contained in this Agreement shall be
deemed to indicate that this Agreement has been entered into for the benefit of
any Person other than the parties hereto.

26. CONFLICT WITH DOCUMENTS. The provisions of this Agreement are intended by
the parties to control any conflicting provisions in the Senior Creditor
Documents or the Junior Creditor Documents, including any covenants prohibiting
further borrowing or encumbrances of Collateral.

27. COUNTERPARTS; TELECOPIED SIGNATURES. This Agreement may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed and delivered shall be deemed to be an original
and all of which counterparts taken together shall constitute but one and the
same instrument. Any signature delivered by a party by facsimile transmission
shall be deemed to be an original signature hereto.

28. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and shall inure
to the benefit of the parties hereto and their respective successors and
assigns. In no event, however, shall either party hereto transfer or assign any
Lien that it may have in any of the Collateral to any Person unless the
transferee or assignee thereof shall first agree in writing to be bound by the
terms of this Agreement the same as if an original signatory hereto.
Notwithstanding the immediately preceding sentence, any Person(s) whose loans or
advances to any Borrowers hereafter are used to refinance and pay in full the
Senior Creditor Obligations shall be deemed for all purposes hereof to be the
successor to Agent and Senior Creditors, and from and after the date of any such
refinancing in satisfaction in full of the Senior Creditor Obligations such
Person(s) shall be deemed a party hereto in the place and stead of Agent and
Senior Creditors as if such Person(s) had been the original signatories hereto,
and all loans, advances, liabilities, debit balances, covenants and duties at
any time or times owed by Eltrax and any other Borrowers to such successor to
Agent and Senior Creditors, whether direct or indirect, absolute or contingent,
secured or unsecured, due or to become due, then existing or thereafter arising,
including any renewals, extensions, modifications, or replacements of any of the
foregoing, shall be deemed for all purposes hereunder to constitute and be
Senior Creditor Obligations.

29. FURTHER ASSURANCES. Each of the parties hereto agrees to execute such
amendments to financing statements and other documents as may be necessary to
reflect of record the existence of this Agreement and the relative priorities
established pursuant to paragraph 3 hereof.

30. SEVERABILITY. Wherever possible, each provision of this Agreement shall be
interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this

<PAGE>   13

Agreement shall be prohibited by or invalid under applicable law, such provision
shall be ineffective only to the extent of such prohibition or invalidity,
without invalidating the remainder of such provision or the remaining provisions
of this Agreement.

31. ENTIRE AGREEMENT; AMENDMENTS. This Agreement expresses the entire
understanding and agreement of the parties hereto with respect to the subject
matter hereof and supersedes all prior understandings and agreements of the
parties regarding the same subject matter. This Agreement may not be amended or
modified except by a writing signed by the parties hereto.

32. JURY TRIAL WAIVER. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, EACH
PARTY HERETO HEREBY WAIVES ALL RIGHTS TO A TRIAL BY JURY IN CONNECTION WITH ANY
ACTION, SUIT OR OTHER PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT.

         IN WITNESS WHEREOF, the parties hereto have executed this Agreement on
the day and year first above written.
