             NON-NEGOTIABLE SUBORDINATED CONVERTIBLE PROMISSORY NOTE

$5,000,000.00                                                      June 23, 2000

         FOR VALUE RECEIVED, the undersigned, ELTRAX SYSTEMS, INC., a Minnesota
corporation ("Maker"), promises to pay to the order of CEREUS TECHNOLOGY

interest thereon as provided herein, in such coin or currency of the United

payment of public and private debts. This Amended and Restated Non-Negotiable
Subordinated Convertible Promissory Note (the "Note") 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


--------------------
(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.



                                       6
<PAGE>   7

         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 (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



                                       7
<PAGE>   8

         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 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




                                       8
<PAGE>   9


         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 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



                                       9

         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 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 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



                                       11

any, for the payment thereof, are subordinated in all respects pursuant to, and

waived or modified, but only upon the written consent of Maker and Holder.

(as defined below), this Note shall not be transferable, negotiable or
assignable otherwise than by the operation of law without the prior written
consent of Maker, and any purported transfer, negotiation or assignment of this
Note without the prior written consent of Maker shall be void and of no force or
effect. The term "Permitted Transfers" shall mean transfers between Holder and
its Subsidiaries.

pursuant to the terms of the Bridge Loan Note which is attached as Exhibit A to
the Loan Agreement and which, under certain circumstances, may be converted into

         WHEREAS, the Loan Agreement further provides that, if that certain

         NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties agree as follows:

<PAGE>   17

         2.       DEMAND AND FORM S-3 REGISTRATIONS.

                  2A.      REQUEST FOR REGISTRATION.

                           (i)      At any time and from time to time for the
period (the "Demand Period") that is one (1) year after the later to occur of
(x) the date that the Bridge Loan Note is converted, and (y) the date that the
Warrant is exercised, the Investor may request an underwritten registration
under the Securities Act of 1933, as amended (the "Securities Act"), of all or
part (but not less than 100,000 shares) of its Registrable Stock (the "Demand
Registration"), subject to the terms and conditions of this Agreement. Any
request (a "Registration Request") for the Demand Registration shall specify the
approximate number of shares of Registrable Stock requested to be registered
(but not less than a majority of the total number of shares of Registrable Stock
then outstanding).

                           (ii)     Subject to subsection (i) above and
paragraph 2F, the Investor will be entitled to request one (1) Demand
Registration at any time during the Demand Period.

                           (iii)    A  registration will not count as the
Demand Registration paid for by the Company (as provided in paragraph 5B) unless
the Investor is able to register and sell at least 50% of the Registrable Stock
requested to be included in such registration.

                           (iv)     The Company will not include in any Demand
Registration any securities other than shares of Registrable Stock and
securities to be registered for offering and sale on behalf of the Company
without the prior written consent of the Investor. If the managing
underwriter(s) of the offering to be effected pursuant to the Demand
Registration advise the Company in writing that in their opinion the number of
shares of Registrable Stock and, if permitted hereunder, other securities in
such offering, exceeds the number of shares of Registrable Stock and other
securities, if any, which can be sold in an orderly manner in such offering
within a price range acceptable to the Investor, the Company will include in
such registration, prior to the inclusion of any securities which are not shares
of Registrable Stock, the number of shares of Registrable Stock requested to be
included which in the opinion of such underwriters can be sold in an orderly
manner within the price range of such offering.

                  2B.      REGISTRATIONS ON FORM S-3. The Company shall use
commercially reasonable efforts to qualify for registration of its securities on
Form S-3 or any comparable or successor form or forms ("Form S-3"). After the
Company has so qualified, in addition to the rights set forth in paragraph 2A
hereof, at any time and from time to time (but subject to the proviso in
paragraph 2B(i) hereof) for the period that is one (1) year after the later to
occur of (x) the date that the Bridge Loan Note is converted, and (y) the date
that the Warrant Agreement is exercised, the Investor may make a Registration
Request for registration of not less than 100,000 shares of the Registrable
Stock on Form S-3 (the "S-3 Registration"). Such Registration Request shall be
in writing and shall state the number of shares of Registrable Stock proposed to
be disposed of and the intended method of distribution of such shares by the
Investor.

                           (i)      The Investor will be entitled to require the
Company to file two (2) registration statements on Form S-3; provided, however,
that the Investor may not require the


                                       17
<PAGE>   18

Company to file a registration statement on Form S-3 more than once during any
calendar year.

                      (ii)     A registration will not count as the S-3
Registration paid for by the Company (as provided in paragraph 5B) unless the
Investor is able to register and sell at least 50% of the Registrable Stock
requested to be included in such registration.

                      (iii)    The Company will not include in the S-3
Registration any securities other than shares of Registrable Stock and
securities to be registered for offering and sale on behalf of the Company
without the prior written consent of the Investor. If the managing
underwriter(s), if any, of the offering to be effected pursuant to an S-3
Registration advise the Company in writing that in their opinion the number of
shares of Registrable Stock and, if permitted hereunder, other securities in
such offering, exceeds the number of shares of Registrable Stock and other
securities, if any, which can be sold in an orderly manner in such offering
within a price range acceptable to the Investor, the Company will include in
such registration, prior to the inclusion of any securities which are not shares
of Registrable Stock, the number of shares of Registrable Stock requested to be
included which in the opinion of such underwriters can be sold in an orderly
manner within the price range of such offering.

                  2C. SELECTION OF UNDERWRITER. The Investor or the holders of a
majority of the then outstanding Registrable Stock proposed to be registered, as
the case may be, will have the right to select the managing underwriter or
underwriters to manage the offering, subject to the Company's approval, which
will not be unreasonably withheld, provided that the managing underwriter or
underwriters shall be the firm or firms that managed the Company's most recently
completed underwritten public offering of Common Stock unless the Investor or
the holders of a majority of the then outstanding Registrable Stock proposed to
be registered, as the case may be, shall object to such firm or firms for
reasons related to the ability of such firm or firms to effectively manage the
offering, and the Company may consent to the selection of such other managing
underwriter or underwriters in such event.

                  2D. DELAYED REGISTRATIONS. Notwithstanding anything in this
Section 2 to the contrary, the Company may delay any Demand Registration or S-3
Registration for a period of not more than sixty (60) days from the date a
Registration Request is made upon certification by an executive officer of the
Company that such registration might (i) materially interfere with or affect the
negotiation or completion of any transaction that is being contemplated by the
Company (whether or not a final decision has been made to undertake such
transaction) at the time the right to delay is exercised, or (ii) involve
initial or continuing disclosure obligations that would not be in the best
interests of the Company and its shareholders.

                  2F. TERMINATION OF REGISTRATION RIGHTS. The Investor's right
to request a Demand Registration, S-3 Registration or Piggyback Registration (as
hereinafter defined) shall terminate at such time as the Investor can sell all
of the Registrable Stock in accordance with Rule 144(k) under the Securities
Act.

         3.       PIGGYBACK REGISTRATIONS.

                  3A. RIGHT TO PIGGYBACK. If the Company proposes to register
any of its


                                       18
<PAGE>   19


securities under the Securities Act (other than pursuant to the Demand
Registration, an S-3 Registration, a registration on Form S-4, a registration
solely in connection with an employee benefit or stock ownership plan or a shelf
registration filed under Rule 415(a)(1)(viii) promulgated under the Securities
Act) and the registration form to be used may be used for the registration of
Registrable Stock, then the Company will give prompt written notice to the
Investor of its intention to effect such a registration (the "Piggyback
Registration"). Subject to subparagraphs 3B and 3C below, the Company will
include in such registration all shares of Registrable Stock which the Investor
requests the Company to include in such registration by written notice given to
the Company within fifteen (15) days after the date of sending of the Company's
notice, subject to the terms and provisions of this Section 3.

                  3B.  PRIORITY ON PRIMARY REGISTRATIONS. If a Piggyback
Registration relates to an underwritten public offering of equity securities by
the Company and the managing underwriters advise the Company in writing that in
their opinion the number of securities requested to be included in such
registration exceeds the number which can be sold in an orderly manner in such
offering within a price range acceptable to the Company, the Company will
include in such registration (i) first, the securities proposed to be sold by
the Company, (ii) second, any Registrable Stock requested to be included in such
registration, pro rata among the holders of such Registrable Stock on the basis
of the number of shares owned by each such holder, and (iii) third, other
securities requested to be included in such registration.

                  3C.  PRIORITY ON SECONDARY REGISTRATIONS. If a Piggyback
Registration relates to an underwritten public offering of equity securities by
holders of the Company's securities and the managing underwriters advise the
Company in writing that in their opinion the number of securities requested to
be included in such registration exceeds the number which can be sold in an
orderly manner in such offering within a price range acceptable to the holders
initially requesting such registration, the Company will include in such
registration (i) first, the Registrable Stock requested to be included in such
registration pro rata among the holders of such Registrable Stock on the basis
of the number of the Registrable Stock owned by each such holder; and (ii)
second, securities other than Registrable Stock.

              4.  REGISTRATION PROCEDURES. Whenever the Investor has requested
that any Registrable Stock be registered pursuant to this Agreement, the Company
will use its best efforts to effect the registration and the sale of such
Registrable Stock in accordance with the intended method of distribution thereof
and will, as expeditiously as possible (subject to the terms hereof):

                  (i)  prepare and file with the Securities and Exchange
Commission a registration statement with respect to such Registrable Stock and
use its best efforts to cause such registration statement to become effective,
provided that before filing a registration statement or prospectus or any
amendments or supplements thereto in connection with a Demand Registration or
S-3 Registration, as the case may be, the Company will furnish to the counsel
selected by the Investor copies of all such documents proposed to be filed,
which documents will be subject to the review of such counsel;

                  (ii) prepare and file with the Securities and Exchange
Commission such amendments and supplements to such registration statement and
the prospectus used in


                                       19
<PAGE>   20


connection therewith as may be necessary to keep such registration statement
effective for a period of not less than the reasonable time necessary to permit
the Investor to complete the distribution described in such registration
statement, and comply with the provisions of the Securities Act with respect to
the disposition of all securities covered by such registration statement during
such period in accordance with the intended methods of distribution by the
sellers thereof set forth in such registration statement;

                  (iii)  furnish to the Investor such number of copies of such
registration statement, each amendment and supplement thereto, the prospectus
included in such registration statement (including each preliminary prospectus)
and such other documents as the Investor may reasonably request in order to
facilitate the disposition of the Registrable Stock owned by the Investor;

                  (iv)   use its best efforts to register or qualify such
Registrable Stock under the securities or blue sky laws of such jurisdictions as
the Investor reasonably requests and do any and all other acts and things which
may be reasonably necessary or advisable to enable the Investor to consummate
the disposition in such jurisdictions of the Registrable Stock owned by the
Investor, provided that the Company will not be required (i) to qualify
generally to do business in any jurisdiction where it would not otherwise be
required to qualify but for this subparagraph, (ii) to subject itself to
taxation in any such jurisdiction or (iii) to consent to general service of
process in any such jurisdiction;

                  (v)    notify the Investor, at any time when a prospectus
relating thereto is required to be delivered under the Securities Act, of the
happening of any event as a result of which the prospectus included in such
registration statement contains an untrue statement of a material fact or omits
any fact necessary to make the statements therein not misleading, and, at the
request of any the Investor, the Company will prepare a supplement or amendment
to such prospectus so that, as thereafter delivered to the Investor, such
prospectus will not contain an untrue statement of a material fact or omit to
state any fact necessary to make the statements therein not misleading;

                  (vi)   use its best efforts to cause all such Registrable
Stock to be listed on each securities exchange on which similar securities
issued by the Company are then listed and to be qualified for trading on each
system on which similar securities issued by the Company are from time to time
qualified;

                  (vii)  provide a transfer agent and registrar for all such
Registrable Stock not later than the effective date of such registration
statement and thereafter maintain such a transfer agent and registrar;

                  (viii) enter into such customary agreements (including
underwriting agreements in customary form) and take all such other actions as
the Investor reasonably requests in order to expedite or facilitate the
disposition of such Registrable Stock;

                  (ix)   make available for inspection by any underwriter
participating in any disposition pursuant to such registration statement and any
attorney, accountant or other agent


                                       20

<PAGE>   21

retained by any such underwriter, all financial and other records, pertinent
corporate documents and properties of the Company, and cause the Company's
officers, directors, employees and independent accountants to supply all
information reasonably requested by any such underwriter, attorney, accountant
or agent in connection with such registration statement;

                  (x)  otherwise use its best efforts to comply with all
applicable rules and regulations of the Securities and Exchange Commission, and
make available to its security holders, as soon as reasonably practicable, an
earnings statement covering the period of at least twelve (12) months beginning
with the first day of the Company's first full calendar quarter after the
effective date of the registration statement, which earnings statement shall
satisfy the provisions of Section 11(a) of the Securities Act and Rule 158
thereunder;

                 (xi)  in the event of the issuance of any stop order suspending
the effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any Registrable Stock included in such registration statement for sale in any
jurisdiction, the Company will use its reasonable best efforts promptly to
obtain the withdrawal of such order; and

                 (xii) furnish to the Investor a copy, or upon request, a
signed counterpart, addressed to the Investor (and the underwriters, if any) of
(a) an opinion of counsel for the Company, dated the effective date of such
registration statement (or, if such registration includes an underwritten public
offering, dated the date of closing under the underwriting agreement), and (b) a
"comfort" letter, dated the effective date of such registration statement (or,
if such registration includes an underwritten public offering, dated the date of
the closing under the underwriting agreement), signed by the independent public
accountants who have audited the Company's financial statements included in such
registration statement, covering substantially the same matters with respect to
such registration statement (and the prospectus included therein) and, in the
case of the accountants' letter, with respect to events subsequent to the date
of such financial statements, as are customarily covered in opinions of issuer's
counsel and in accountants letters delivered to the underwriters in underwritten
public offerings of securities and such other matters as the underwriter may
reasonably request.

         5.      REGISTRATION EXPENSES.

                 5A.   DEFINITION. The term "Registration Expenses" means all
expenses incident to the Company's performance of or compliance with this
Agreement, including, without limitation, all registration and filing fees, fees
and expenses of compliance with securities and blue sky laws, printing,
messenger and delivery expenses, and fees and expenses of counsel for the
Company and all independent certified public accountants, underwriters
(excluding underwriting discounts and commissions, which shall be paid by the
selling stockholders out of the proceeds of the offering) and other Persons
retained by the Company.

                 5B.   PAYMENT. The Company shall pay the Registration Expenses
in connection with one (1) Demand Registration, or two (2) S-3 Registrations,
and any and all Piggyback Registrations. In connection with each Demand
Registration, the S-3 Registration and each Piggyback Registration, the Company
will reimburse the holders of Registrable Stock covered by


                                       21

<PAGE>   22

such registration for the reasonable fees and disbursements of one counsel
chosen by the Investor.

         6.       INDEMNIFICATION.

                  6A. INDEMNIFICATION BY THE COMPANY. The Company agrees to
indemnify, to the extent permitted by law, the Investor, its officers and
directors and each Person who controls such holder (within the meaning of the
Securities Act) against all losses, claims, damages, liabilities and expenses
caused by any untrue or alleged untrue statement of material fact contained in
any registration statement, prospectus or preliminary prospectus or any
amendment thereof or supplement thereto, or any omission or alleged omission of
a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as the same are caused by or
contained in any information furnished in writing to the Company by such holder
expressly for use therein or by such holder's or an underwriter's failure to
deliver a copy of the registration statement or prospectus or any amendments or
supplements thereto after the Company has furnished such holder or underwriter
with a sufficient number of copies of the same, provided that the obligations of
the Company hereunder shall not apply to amounts paid in settlement of any such
losses, claims, damages, liabilities or expenses (or actions in respect thereof)
if such settlement is effected without the consent of the Company (which consent
shall not be unreasonably withheld). In connection with an underwritten
offering, the Company will indemnify such underwriters, their officers and
directors and each Person who controls such underwriters (within the meaning of
the Securities Act) to the same extent as provided above with respect to the
indemnification of the Investor unless otherwise provided in the underwriting
agreement.

                  6B. INDEMNIFICATION BY HOLDERS. In connection with any
registration statement in which the Investor is participating, the Investor will
furnish to the Company in writing such information and affidavits as the Company
reasonably requests for use in connection with any such registration statement
or prospectus and, to the extent permitted by law, will indemnify the Company,
its directors and officers and each Person who controls the Company (within the
meaning of the Securities Act) against any losses, claims, damages, liabilities
and expenses resulting from any untrue or alleged untrue statement of material
fact contained in the registration statement, prospectus or preliminary
prospectus or any amendment thereof or supplement thereto or any omission or
alleged omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading, but only to the extent that such
untrue statement or omission is contained in any information or affidavit so
furnished in writing by the Investor and stated to be specifically for use
therein, provided that (i) the obligation to indemnify will be limited to the
net amount of proceeds received by the Investor from the sale of Registrable
Stock pursuant to such registration statement and (ii) the obligations of the
Investor hereunder shall not apply to amounts paid in settlement of any such
losses, claims, damages, liabilities or expenses (or actions in respect thereof)
if such settlement is effected without the consent of the Investor (which
consent shall not be unreasonably withheld).

                  6C. NOTICE; DEFENSE OF CLAIMS. Any Person entitled to
indemnification hereunder will give prompt written notice to the indemnifying
party of any claim with respect to which it seeks indemnification, and such
indemnifying party will, upon request of the indemnified party, assume the
defense of such claim with counsel reasonably satisfactory to the indemnified


                                       22
<PAGE>   23

party. If such defense is assumed, the indemnifying party will not be subject to
any liability for any settlement made by the indemnified party without its
consent (but such consent will not be unreasonably withheld). An indemnifying
party who assumes the defense of a claim will not be obligated to pay the fees
and expenses of separate counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the written opinion of
counsel to the indemnified party a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
claim, in which case the indemnified party may retain its own counsel (which
counsel will be reasonably satisfactory to the indemnifying party) and the fees
and expenses of such counsel will be paid by the indemnifying party.

                  6D. CONTRIBUTION. If the indemnification provided for in this
Section 6 is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any loss, liability, claim, damage or expense
referred to herein, then the indemnifying party, in lieu of indemnifying such
indemnified party hereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such loss, liability, claim, damage, or
expense in such proportion as is appropriate to reflect the relative fault of
the indemnifying party, on the one hand, and of the indemnified party, on the
other, in connection with the statements or omissions that resulted in such
loss, liability, claim, damage, or expense, as well as any other relevant
equitable considerations. The relative fault of the indemnifying party and of
the indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission. The obligation to contribute will be limited to the
amount by which the net amount of proceeds received by the Investor from the
sale of Registrable Stock exceeds the amount of losses, liabilities, damages,
and expenses which the Investor has otherwise been required to pay by reason of
such statements or omissions.

                  6E. SURVIVAL. The indemnification and contribution provided
for under this Agreement will remain in full force and effect regardless of any
investigation made by or on behalf of the indemnified party or any officer,
director or controlling Person of such indemnified party and will survive the
transfer of securities.

           7.     PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. No Person may
participate in any registration hereunder which is underwritten unless such
Person (i) agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Person or Persons entitled hereunder
to approve such arrangements, and (ii) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents required under the terms of such underwriting arrangements,
provided that the Investor shall not be required to make any representations or
warranties to the Company or the underwriters other than representations and
warranties regarding the Investor as are required by the underwriters.

           8.     MISCELLANEOUS.

                  8A. NO INCONSISTENT AGREEMENTS.  The Company will not
hereafter enter into any agreement with respect to its securities which is
inconsistent with or violates the rights


                                       23
<PAGE>   24

granted to the holders of Registrable Stock in this Agreement.

                  8B.     ADJUSTMENTS AFFECTING REGISTRABLE STOCK.  The Company
will not take any action, or permit any change to occur, with respect to its
securities for the purpose of materially and adversely affecting the ability of
the Investor to include the Registrable Stock in a registration undertaken
pursuant to this Agreement.

               8C. NOTICES. All notices, requests and other communications
required or permitted under this Agreement (collectively, "notices") shall be in

                  8K.   FURTHER ASSURANCES. Each party to this Agreement hereby
covenants and agrees, without the necessity of any further consideration, to
execute and deliver any and all such further documents and take any and all such

                  8M.   LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS. If at any
time or from time to time after the date of this Agreement, the Company shall
enter into any agreement with any holder or prospective holder of any securities
of the Company giving such holder or prospective holder any registration rights
the terms and conditions of which are more favorable than the registration
rights granted to the Investor, then the parties hereto agree that the terms and
conditions of this Agreement shall be immediately amended, without any further
or additional action or notice by the parties hereto, so as to give the Investor
registration rights on terms and conditions no less favorable than the terms and
conditions of the registration rights granted to such holder or prospective
holder. The parties hereto further agree that no single amendment pursuant to
this Section 8M will preclude further or additional amendments upon further or
additional grants of registration rights by the Company.

                  8N.   RULE 144 REPORTING. With a view to making available the
benefits of certain rules and regulations of the Securities and Exchange
Commission that may permit sale of the Registrable Stock to the public without
registration, the Company agrees to use its reasonable efforts to:

                  (i)   Make and keep public information regarding the Company
available as those terms are understood and defined in Rule 144 under the
Securities Act, at all times;

                  (ii)  File with the Securities and Exchange Commission in a
timely manner all reports and other documents required of the Company under the
Securities Act and the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), at any time after it has become subject to such reporting
requirements.

                  (iii) So long as a holder owns any Registrable Stock, furnish
to the holder forthwith upon written request a written statement by the Company
as to its compliance with the reporting requirements of Rule 144, the Securities
Act and the Exchange Act, a copy of the most recent annual or quarterly report
of the Company, and such other reports and documents so filed as a holder of
Registrable Stock may reasonably request in availing itself of any rule or
regulation of the Securities and Exchange Commission allowing a holder of
Registrable Stock to sell any such securities without registration.

         IN WITNESS WHEREOF, this Amended and Restated Registration Rights
Agreement has been executed and delivered by the duly authorized officers of the

                            Warrant for the Purchase
                            of Shares of Common Stock

________________________, 20___                            ____________ Shares


                  FOR VALUE RECEIVED, ELTRAX SYSTEMS, INC., a Minnesota
corporation (the "Company"), hereby certifies that CEREUS TECHNOLOGY PARTNERS,
INC., a Delaware corporation (the "Holder"), is entitled, subject to the
provisions of this Warrant, to purchase from the Company, at any time or from
time to time during the Exercise Period (as hereinafter defined) the number of
fully paid and nonassessable shares of Borrower Common Stock, as defined in the
Loan Agreement (as hereinafter defined), as determined pursuant to Section 9.1
of the Loan Agreement and set forth above, at the applicable Exercise Price (as
hereinafter defined).

                  All capitalized terms used herein shall have the meanings
ascribed to such terms in that certain Bridge Loan and Security Agreement by
and between the Company (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 (the

                                       33


<PAGE>   34

"Loan Agreement"), except to the extent that such capitalized terms are
otherwise defined or limited herein.

                  The number and character of shares of Borrower Common Stock or
other securities to be received upon exercise of this Warrant are subject to
adjustment in accordance with the provisions of Sections 6 and 7 hereof.

                  For purposes of this Warrant, "Warrant Shares" means the
shares of the Borrower Common Stock deliverable upon exercise of this Warrant,
as adjusted from time to time. Unless the context requires otherwise, all
references to the Borrower Common Stock and Warrant Shares in this Warrant
shall, in the event of an adjustment pursuant to Sections 6 and 7 hereof, be
deemed to refer also to any securities or property then issuable upon exercise
of this Warrant as a result of such adjustment.

                  Section 1. Exercise of Warrant. This Warrant may be exercised,
as a whole or in part, at any time or from time to time during the Exercise
Period or, if such day is not a Business Day, then on the next succeeding
Business Day, by presentation and surrender hereof to the Company at the address
set forth in Section 15 hereof (or at such other address as the Company may
hereafter notify the Holder in writing), with the Purchase Form annexed hereto
duly executed and accompanied by proper payment of the aggregate applicable
Exercise Price in lawful money of the United States of America in the form of a
certified or cashier's check to the order of Eltrax Systems, Inc. or by wire
transfer of same day funds, for the number of Warrant Shares specified in such
form. If this Warrant should be exercised in part only, the Company shall, upon
surrender of this Warrant, execute and deliver a new Warrant of like form
evidencing the rights of the Holder to purchase the balance of the Warrant
Shares purchasable hereunder. Upon receipt by the Company of this Warrant and
such Purchase Form, together with the aggregate applicable Exercise Price (as
hereinafter defined) for the number of Warrant Shares specified in such Purchase
Form, at such office, the Company shall issue and deliver to the Holder, in the
name of the Holder, a certificate or certificates for the Warrant Shares. Such
certificate or certificates shall be deemed to have been issued and the Holder
shall be deemed to have become the holder of record of such Warrant Shares as of
the date of the surrender of this Warrant, notwithstanding that the stock
transfer books of the Company shall then be closed or that certificates
representing such Warrant Shares shall not then be actually delivered to the
Holder. The Company shall pay any and all documentary stamp or similar issue or
transfer taxes payable in respect of the issue or delivery of the Warrant
Shares. Notwithstanding the foregoing, the Exercise Price may be paid by
surrendering a part of the Warrant having an aggregate Spread equal to the
aggregate Exercise Price of the portion of the Warrant being exercised. With
respect to the Warrant, "Spread" means the Current Market Value (as hereinafter
defined) of the Warrant Shares issuable upon exercise of such portion of the
Warrant less the Exercise Price of such part of the Warrant, in each case as
adjusted as provided herein.

                  Section 2.  Exercise Period and Exercise Price.

                          (a)      This Warrant shall be  exercisable  during
the period (the "Exercise Period") beginning on the date of execution of this
Warrant (the "Initial Exercise Date") and ending at 5:00 p.m. (Atlanta, Georgia
time) on a date three (3) years after the Initial Exercise

                                       34

<PAGE>   35


Date (the "Termination Date").

                          (b)      "Exercise Price" means $.01 per share of the
Borrower Common Stock, subject to adjustment as herein provided.

                  Section 3. Reservation of Shares. The Company hereby agrees
that at all times there shall be reserved for issuance and delivery upon
exercise of this Warrant all shares of the Borrower Common Stock or other shares
of capital stock of the Company or other property from time to time issuable
upon exercise of this Warrant. All such shares shall be duly authorized and,
when issued upon such exercise in accordance with the terms of this Warrant,
shall be validly issued, fully paid and nonassessable, free and clear of all
liens, security interests, charges and other encumbrances or restrictions on
sale (other than any restrictions on sale pursuant to applicable federal and
state securities laws) and free and clear of all preemptive rights.

                  Section 4. Exchange, Transfer, Assignment or Loss of Warrant.


                          (a)      This Warrant is  exchangeable,  without
expense, at the option of the Holder, upon presentation and surrender hereof to
the Company for other warrants of different denomination, entitling the Holder
thereof to purchase in the aggregate the same number of Warrant Shares and
otherwise carrying the same rights as this Warrant.

                          (b)      This Warrant may be divided or combined by
the Holder with other warrants that carry the same rights upon presentation
hereof at the office of the Company, together with a written notice specifying
the names and denominations in which new warrants are to be issued and signed by
the Holder hereof. The term "Warrant" as used herein includes any warrants into
which this Warrant may be divided or for which it may be exchanged.

                          (c)      Upon receipt by the Company of evidence
satisfactory to it of the loss, theft, destruction or mutilation of this
Warrant, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Warrant, if mutilated, the Company shall execute and deliver a new Warrant of
like tenor and date.

                  Section 5. Rights of the Holder. The Holder shall not, by
virtue hereof, be entitled to any rights of a stockholder in the Company, either
at law or in equity, and the rights of the Holder are limited to those expressed
in this Warrant.

                  Section 6. Antidilution Provisions and Other Adjustments. The
number of Warrant Shares which may be purchased upon the exercise hereof shall
be subject to change or adjustment from time to time as follows:

                          (a)      Stock  Dividends;  Stock Splits;  Reverse
Stock Splits; Reclassifications. In case the Company 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

                                       35

business combination in which the Company is the continuing corporation) the
number of shares of Borrower Common Stock issuable upon exercise of this Warrant
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 the 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 the Company that the Holder would have owned or have been entitled
to receive after the happening of each such event, had this Warrant been
exercised immediately prior to the happening of each such event or any record
date with respect thereto. Each adjustment made pursuant to this Section 6(a)
shall become effective immediately after the effective date of the applicable
event retroactive to the record date, if any, for such event.

                          (b)      Distributions of Debt, Assets,  Subscription
Rights or Convertible Securities. In case the Company 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 the Company, assets (other than cash
dividends payable out of retained earnings or securities (excluding those
referred to in Section 6(a)) (any such evidences of indebtedness, assets, or
securities being referred to in this Section 6(b) as the "assets or
securities"), then in each case the Holder, upon the exercise of this Warrant,
shall be entitled to receive in addition to the shares of Borrower Common Stock
issuable upon exercise of this Warrant, (i) the assets or securities to which
the Holder would have been entitled as a holder of Borrower Common Stock if the
Holder had exercised this Warrant immediately prior to the record date for such
distribution and (ii) 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, the Company shall either (A) deposit the assets or
securities payable to the Holder pursuant hereto in trust for the 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 the Holder or (B) distribute to the Holder the assets
or securities to which it would be entitled upon exercise and, upon any such
distribution pursuant to this clause (B), the provisions of this Section 6(b)
shall no longer apply to such event. Such election shall be made by the Company
by giving written notice thereof to the Holder.

                          For  purposes  of this  Section  6(b),  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.

                          (c)      De Minimis  Adjustments.  Except as
provided in Section 6(d) with reference to adjustments required by such Section
6(d), 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 exercise of each Warrant; provided, however, that
any adjustments which by reason of this Section 6(c) 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.

<PAGE>   37


                          (d)      Adjustments.  In case the Company after
the date hereof shall take any action affecting the Warrant Shares, other than
any action described in Sections 6(a) or 6(b) or in Section 7 hereof, which the
Company's board of directors, acting in the good faith exercise of their
reasonable judgment, determines would have a material adverse effect on the
rights of the Holder, then the Exercise Price, the number of Warrant Shares
and/or the character of the securities receivable upon exercise of this Warrant
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 the Company are then listed or
quoted.

                          (e)      Notice of  Adjustment.  Whenever the number
of shares of Borrower Common Stock or other stock or property issuable upon the
exercise of this Warrant is adjusted, as herein provided, the Company shall
promptly notify the Holder of such adjustment or adjustments.

                          (f)      Adjustments  to Exercise  Price.  The
aggregate exercise price payable upon exercise of this Warrant shall not
increase or decrease upon any adjustment (pursuant to this Section 6) to the
number of Warrant Shares issuable upon exercise of this Warrant. Accordingly,
the per share Exercise Price of the Warrant Shares will be adjusted to reflect
any such adjustment to the number of Warrant Shares issuable as required not to
increase or decrease the aggregate exercise price payable upon exercise of this
Warrant.

                  Section 7. Reclassification. Reorganization, Consolidation or
Merger. In the event of any reclassification, capital reorganization or other
change of outstanding shares of the Borrower Common Stock (other than a
subdivision or combination of the outstanding Borrower Common Stock, a change
in the par value of the Borrower Common Stock or a transaction subject to
Section 6 hereof) or in the event of any consolidation or merger of the Company
with or into another corporation (other than the transactions contemplated by
the Merger Agreement, a merger in which merger the Company 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 exercise of this Warrant or a transaction subject to
Section 6 hereof) or in the event of any sale, lease, transfer or conveyance to
another corporation of the property and assets of the Company 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 the Company 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 the Company hereunder and the
Holder shall have the right thereafter, by exercising this Warrant, to purchase
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 exercise of this Warrant 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

                                       37


<PAGE>   38


as may be practicable to the adjustments provided for in this Warrant. The
foregoing provisions of this Section 7 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 the Company other than Borrower Common Stock, any such issue shall
be treated as an issue of Borrower Common Stock covered by the provisions of
Section 6(a).

                  Section 8. Transfer to Comply with the Securities Act. Neither
this Warrant, nor any of the Warrant Shares, nor any interest therein, may be
sold, assigned, pledged, hypothecated, encumbered or in any other manner
transferred or disposed of, as a whole or in part, except in compliance with
applicable United States federal and state securities or Blue Sky laws and the
terms and conditions hereof. Each Warrant shall bear a legend in substantially
the same form as the legend set forth on the first page of this initial Warrant.
Each certificate for Warrant Shares issued upon exercise of this Warrant, unless
at the time of exercise such exercise is registered under the Securities Act of
1933, as amended (the "Securities Act"), shall bear a legend substantially in
the following form:

         "The securities represented by this certificate have not been
         registered under the Securities Act of 1933 or registered or qualified
         under the securities or Blue Sky laws of any state. Neither these
         securities nor any interest or participation therein may be sold,
         assigned, pledged, hypothecated, encumbered or in any other manner
         transferred or disposed of unless (i) registered under an effective
         registration statement under the Securities Act of 1933 and in full
         compliance with the applicable rules and regulations thereunder and
         applicable state securities or Blue Sky laws, (ii) pursuant to Rule 144
         of such Act or (iii) unless Eltrax Systems, Inc. receives an opinion of
         counsel for the holder of this certificate, reasonably satisfactory to
         Eltrax Systems, Inc., stating that such sale, assignment, pledge,
         hypothecation, encumbrance or other manner of transfer or disposition
         is exempt from the registration and prospectus delivery requirements of
         the Securities Act of 1933 and applicable state securities or Blue Sky
         law."

Any certificate for any Warrant Shares issued at any time in exchange or
substitution for any certificate for any Warrant Shares bearing such legend
(except a new certificate for any Warrant Shares issued after registration of
such Warrant Shares under the Securities Act) shall also bear such legend
unless, in the opinion of counsel for the Company, the Warrant Shares
represented thereby need no longer be subject to the restriction contained
herein. The provisions of this Section 8 shall be binding upon all subsequent
holders of certificates for Warrant Shares bearing the above legend and all
subsequent Holders of this Warrant, if any. Warrant Shares sold pursuant to a
Registration Statement under the Securities Act pursuant to Section 12 thereof
or sold by the holder thereof in compliance with Rule 144 under the Securities
Act shall thereafter cease to be deemed to be "Warrant Shares" for all purposes
of this Warrant.

Warrant and the Company shall maintain, so long as any other shares of the
Borrower Common Stock shall be so listed, all shares of Borrower Common Stock

shall so list on each national securities exchange, and shall maintain such
listing of, any other shares of capital stock of the Company issuable upon the
exercise of this Warrant if and so long as any shares of capital stock of the

comply with the reporting requirements of Sections 13 and 15(d) of the Exchange
Act to the extent it is required to do so under the Exchange Act, and shall
likewise comply with all other applicable public information reporting
requirements of the Securities and Exchange Commission (including those required
to make available the benefits of Rule 144 under the Securities Act) to which it
may from time to time be subject. The Company shall also cooperate with the
holder of this Warrant and the holder of any Warrant Shares in supplying such
information as may be necessary for such holder to complete and file any
information reporting forms currently or hereafter required by the Commission as
a condition to the availability of Rule 144 or any successor rule under the
Securities Act for the sale of this Warrant or the Warrant Shares. The
provisions of this Section 10 shall survive termination of this Warrant, whether
upon exercise of this Warrant in full or otherwise until such time as the
Warrant Shares have been sold by the Holder or are eligible for sale under Rule
144(k). The Company shall also provide to holders of this Warrant the same
information that it provides to holders of the Borrower Common Stock.

                  Section 11. Registration Rights. The Company and the Holder
agree that the shares of Borrower Common Stock and other securities (as the case
may be) underlying this Warrant shall be subject to the terms and conditions of
