shall be identical in all respects to the Initial Tranche Debentures except that

Purchasers of such executed definitive agreement and, provided further that,
such consent shall not be unreasonably denied; it being understood that,
customary and standard representations, warranties and conditions set forth in

                         REPRESENTATIONS AND WARRANTIES

the following representations and warranties to each Purchaser:

         (a) Organization and Qualification. The Company is a corporation duly

of Minnesota with the requisite corporate power and authority to own and use its
properties and assets and to carry on its business as currently conducted. The
Company has no subsidiaries other than as set forth in Schedule 2.1(a)
(collectively the "Subsidiaries"). Each of the Subsidiaries is an entity, duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation or organization (as applicable), with the
requisite corporate power and authority to own and use its properties and assets
and to carry on its business as currently conducted. Each of the Company and the
Subsidiaries is duly qualified to do business and is in good standing as a
foreign corporation in each jurisdiction in which the nature of the business
conducted or property owned by it makes such qualification necessary, except
where the failure to be so qualified or in good standing, as the case may be,
could not be reasonably expected to, individually or in the aggregate, (x)
adversely affect the legality, validity or

                                       3
<PAGE>   5

enforceability of the Securities (as defined below) or any of this Agreement,
the Registration Rights Agreement, the Debenture or the Transfer Agent
Instructions (collectively, the "Transaction Documents"), (y) have or result in
a material adverse effect on the results of operations, assets, prospects, or
condition (financial or otherwise) of the Company and the Subsidiaries, taken as
a whole, or (z) adversely impair the Company's ability to perform fully on a
timely basis its obligations under any of the Transaction Documents (any of (x),
(y) or (z), a "Material Adverse Effect").

         (b) Authorization; Enforcement. The Company has the requisite corporate
power and authority to enter into and to consummate the transactions
contemplated by each of the Transaction Documents and otherwise to carry out its
obligations thereunder. The execution and delivery of each of the Transaction
Documents by the Company and the consummation by it of the transactions
contemplated thereby have been duly authorized by all necessary action on the
part of the Company and no further action is required by the Company. Each of
the Transaction Documents has been duly executed by the Company and, when
delivered in accordance with the terms hereof, will constitute the valid and
binding obligation of the Company enforceable against the Company in accordance
with its terms, except to the extent that enforcement thereof may be limited by
(i) bankruptcy, insolvency, reorganization, moratorium or similar laws now or
hereafter in effect relating to creditors' rights generally and (ii) general
principles of equity (regardless of whether enforceability is considered in a
proceeding at law or in equity) and except to the extent that rights to
indemnification and contribution contained in this Agreement may be limited by
federal or state securities laws on public policy relating thereto. Neither the
Company nor any Subsidiary is in violation of any of the provisions of its
respective certificate or articles of incorporation, by-laws or other charter or
organizational documents.

outstanding capital stock of the Company is set forth in Schedule 2.1(c). Except
as disclosed in Schedule 2.1(c), the Company owns all of the capital stock of

rights, nor is any holder of securities of the Company or any Subsidiary
entitled to preemptive or similar rights arising out of any agreement or
understanding with the Company or any Subsidiary by virtue of any of the
Transaction Documents. Except as a result of the purchase and sale of the
Debentures and the Warrants and except as disclosed in Schedule 2.1(c), there
are no outstanding options, warrants, script rights to subscribe to, calls or
commitments of any character whatsoever relating to, or securities, rights or
obligations convertible into or exchangeable for, or giving any Person any right
to subscribe for or acquire, any shares of Common Stock, or contracts,
commitments, understandings, or arrangements by which the Company or any
Subsidiary is or may become bound to issue additional shares of Common Stock, or
securities or rights convertible or exchangeable into shares of Common Stock.

         (d) Issuance of the Debentures and the Warrants. The Debentures and the
Warrants will be duly and validly issued, free and clear of all liens,
encumbrances and rights of first refusal of any kind (collectively, "Liens"). On
the date hereof and on each Closing Date, the Company will have (and will, at
all times while Debentures and Warrants are

                                       4

outstanding, maintain) an adequate reserve of duly authorized shares of Common
Stock, reserved for issuance to the holders of such Debentures and Warrants, to
enable it to perform its conversion, exercise and other obligations thereunder.
The Company has duly reserved 2,520,000 shares of Common Stock for issuance to
the Purchasers as Underlying Shares upon conversion of the Debentures and the
Warrants. The shares of Common Stock issuable upon conversion of the Debentures
and upon exercise of the Warrants are collectively referred to herein as the
"Underlying Shares." The Debentures, the Warrants and the Underlying Shares are
collectively referred to herein as, the "Securities." When issued in accordance
with the Debentures and the Warrants, the Underlying Shares will be duly

all Liens.

         (e) No Conflicts. The execution, delivery and performance of the
Transaction Documents by the Company and the consummation by the Company of the
transactions contemplated thereby do not and will not (i) conflict with or
violate any provision of the Company's or any Subsidiary's certificate or
articles of incorporation, bylaws or other charter documents (each as amended
through the date hereof), or (ii) subject to obtaining the Required Approvals

which any property or asset of the Company or any Subsidiary is bound or
affected, or (iii) result in a violation of any law, rule, regulation, order,

clauses (ii) and (iii), as could not reasonably be expected to, individually or
in the aggregate, have or result in a Material Adverse Effect. The business of
the Company is not being conducted in violation of any law, ordinance or
regulation of any governmental authority, except for violations which,
individually or in the aggregate, could not reasonably be expected to have or
result in a Material Adverse Effect.

         (f) Filings, Consents and Approvals. Neither the Company nor any
Subsidiary is required to obtain any consent, waiver, authorization or order of,

capacity, "Agent") (as at any time amended, the "PNC Agreement"), and (v) in all
other cases where the failure to obtain such consent, waiver, authorization or
order, or to give such notice or make such filing or registration could not
reasonably be expected to have or result in, individually or in the aggregate, a
Material Adverse Effect (collectively, the "Required Approvals").

         (g) Litigation; Proceedings. There is no action, suit, inquiry, notice
of violation, proceeding or investigation pending or, to the knowledge of the
Company, threatened against or affecting the Company or any of its Subsidiaries
or any of their respective properties before or by any court, arbitrator,

county, local or foreign) (collectively, an "Action") which (i) adversely
affects or challenges the legality, validity or enforceability of any of the
Transaction Documents or the Securities or (ii) could reasonably be expected to,

warranties of the Purchasers set forth in Sections 2.2(b)-(g), the offer,
issuance and sale of the Securities to the Purchasers as contemplated hereby are
exempt from the registration requirements of the Securities Act of 1933, as
amended (the "Securities Act"). Neither the Company nor any Person acting on its
behalf has taken or is, to the knowledge of the Company, contemplating taking
any action which could subject the offering, issuance or sale of the Securities

behalf of other Persons for fees of a type contemplated in this Section that may

have rights to use, all patents, patent applications, trademarks, trademark

have a Material Adverse Effect (collectively, the "Intellectual Property
Rights"). Neither the Company nor any Subsidiary has received a written notice
that the Intellectual Property Rights used by the Company or its Subsidiaries

certificates, authorizations and permits issued by the appropriate federal,
state or foreign regulatory authorities necessary to conduct their respective
businesses as described in the SEC Documents and are operating their respective
businesses in compliance with the terms thereof, except where the failure to
possess such permits or operate their business could not, individually or in the
aggregate, reasonably be expected to have or result in a Material Adverse

                                       8
<PAGE>   10

Effect ("Material Permits"), and neither the Company nor any such Subsidiary has
received any notice of proceedings relating to the revocation or modification of
any Material Permit.

         (s) Title. The Company and the Subsidiaries have good and marketable
title in fee simple to all real property owned by them which is material to the
business of the Company and its Subsidiaries and good and marketable title in
all personal property owned by them which is material to the business of the
Company and its Subsidiaries, in each case free and clear of all Liens, except
for Liens of the Agent and Cereus and Liens that do not materially affect the
value of such property and do not interfere with the use made and proposed to be
made of such property by the Company and its Subsidiaries. Any real property and
facilities held under lease by the Company and its Subsidiaries are held by them

with respect to any of the employees of the Company.

         (v) Non-Public Information. The Company confirms that neither it nor
any other Person acting on its behalf has provided any of the Purchasers or
their agents or counsel with any information with respect to the Company that
constitutes or might constitute material non-public information. The Company
understands and confirms that the Purchasers shall be relying on the foregoing
representations in effecting transactions in securities of the Company. All
disclosure provided to the Purchasers regarding the Company, its business and

under which they were made, not misleading.

    2.2 Representations and Warranties of the Purchasers. Each Purchaser hereby
for itself and for no other Purchaser, represents and warrants to the Company as
follows:

         (a) Organization; Authority. Such Purchaser is an entity duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its organization with the requisite corporate or partnership
power and authority to enter into and to consummate the

                                       9
<PAGE>   11

transactions contemplated by the Transaction Documents and otherwise to carry
out its obligations thereunder. The execution, delivery and performance by such
Purchaser of this Agreement and the Registration Rights Agreement and the
consummation by it of the transaction contemplated hereby and thereby, including
purchase by such Purchaser of the Securities hereunder has been duly authorized
by all necessary action on the part of such Purchaser. Each of this Agreement
and the Registration Rights Agreement has been duly executed by such Purchaser,
and when delivered by such Purchaser in accordance with the terms hereof, will
constitute the valid and legally binding obligation of such Purchaser,
enforceable against it in accordance with its terms, except to the extent that
enforcement thereof may be limited by (i) bankruptcy, insolvency,
reorganization, moratorium or similar laws now or hereafter in effect relating
to creditors' rights generally and (ii) general principles of equity (regardless
of whether enforceability is considered in a proceeding at law or in equity) and
except to the extent that rights to indemnification and contribution contained
in this Agreement may be limited by federal or state securities laws on public
policy relating thereto.

         (b) Investment Intent. Such Purchaser is acquiring the Securities as
principal for its own account for investment purposes only and not with a view
to or for distributing or reselling such Securities or any part thereof, without
prejudice, however, to such Purchaser's right, subject to the provisions of the
Registration Rights Agreement to sell or otherwise dispose of such Securities
pursuant to an effective registration statement under the Securities Act or
under an exemption from such registration and in compliance with applicable
federal and state securities laws. Such Purchaser is acquiring the Securities
hereunder in the ordinary course of its business. Such Purchaser does not have
any agreement or understanding, directly or indirectly, with any Person to
distribute the Securities.

         (c) Purchaser Status. At the time such Purchaser was offered the
Securities, it was, at the date hereof it is, and on each Closing Date and on
each exercise date under the Warrant it will be an "accredited investor" as
defined in Rule 501(a) under the Securities Act.

         (d) Experience of such Purchaser. Such Purchaser, either alone or
together with its representatives, has such knowledge, sophistication and
experience in business and financial matters so as to be capable of evaluating
the merits and risks of the prospective investment in the Securities, and has so
evaluated the merits and risks of such investment.

         (e) Ability of such Purchaser to Bear Risk of Investment. Such
Purchaser is able to bear the economic risk of an investment in the Securities
and is able to afford a complete loss of such investment.

         (f) Access to Information. Such Purchaser acknowledges that it has
reviewed the Disclosure Materials and has been afforded (i) the opportunity to
ask such questions as it has deemed necessary of, and to receive answers from,
representatives of the Company concerning the terms and conditions of the
offering of the Securities and the merits and risks of investing in the
Securities; (ii) access to information about the Company and the Company's
financial condition, results of operations, business, properties, management and
prospects sufficient to enable it to evaluate its investment; and (iii) the
opportunity to obtain

                                       10
<PAGE>   12

such additional information which the Company possesses or can acquire without
unreasonable effort or expense that is necessary to make an informed investment
decision with respect to the investment and to verify the accuracy and
completeness of the information contained in the Disclosure Materials. Neither
such inquiries nor any other investigation conducted by or on behalf of such
Purchaser or its representatives or counsel shall modify, amend or affect such
Purchaser's right to rely on the truth, accuracy and completeness of the
Disclosure Materials and the Company's representations and warranties contained
in the Transaction Documents.

         (g) Reliance. Such Purchaser understands and acknowledges that (i) the
Securities are being offered and sold to it without registration under the
Securities Act in a private placement that is exempt from the registration
provisions of the Securities Act and (ii) the availability of such exemption
depends in part on, and the Company will rely upon the accuracy and truthfulness
of, the foregoing representations, and such Purchaser hereby consents to such
reliance.

         (h) Limitation. The Company acknowledges and agrees that no Purchaser
makes or has made any representations or warranties with respect to the
transactions contemplated hereby other than those specifically set forth in this
Section 2.2.

                                    ARTICLE 3

                         OTHER AGREEMENTS OF THE PARTIES

    3.1 Transfer Restrictions.

         (a) Securities may only be disposed of pursuant to an effective
registration statement under the Securities Act, or pursuant to an available
exemption from or in a transaction not subject to the registration requirements
of the Securities Act, and in compliance with any applicable federal and state
securities laws. In connection with any transfer of Securities other than
pursuant to an effective registration statement or to the Company, except as
otherwise set forth herein, the Company may require the transferor thereof to
provide to the Company an opinion of counsel selected by the transferor, such
counsel and the form and substance of which opinion shall be reasonably
satisfactory to counsel for the Company, to the effect that such transfer does
not require registration of such transferred Securities under the Securities
Act. Notwithstanding the foregoing, the Company, without requiring a legal
opinion as described in the immediately preceding sentence, hereby consents to
and agrees to register on the books of the Company and with any transfer agent
for the securities of the Company any transfer of Securities by a Purchaser to
an Affiliate (as such term is defined in Rule 501(a) under the Securities Act)
of such Purchaser or to one or more funds or managed accounts under common
management with such Purchaser, and any transfer among any such Affiliates or
one or more funds or managed accounts, provided that the transferee certifies to
the Company that it is an "accredited investor" as defined in Rule 501(a) under
the Securities Act and that it is acquiring the Securities solely for investment
purposes (subject to the qualifications hereof). Any such transferee shall agree
in writing to be bound by the terms of

                                       11

<PAGE>   13

this Agreement and shall have the rights of a Purchaser under this Agreement and
the Registration Rights Agreement.

         (b) The Purchasers agree to the imprinting, so long as is required by
Section 3.1(c), of the following legend on the Securities:

    NEITHER THESE SECURITIES NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE
    [CONVERTIBLE] [EXERCISABLE] HAVE BEEN REGISTERED WITH THE SECURITIES AND
    EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE
    UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS
    AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD
    EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES
    ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT
    SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN
    ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS.

         (c) Underlying Shares shall not contain the legend set forth above nor
any other legend if the conversion of Debentures or exercise of the Warrants
occurs at any time while an Underlying Shares Registration Statement for the
applicable Underlying Shares is effective under the Securities Act or, in the
event there is not an effective Underlying Shares Registration Statement, at
such time, in the opinion of counsel to the Company, such legend is not required
under applicable requirements of the Securities Act (including judicial
interpretations and pronouncements issued by the staff of the Commission). The
Company shall cause its counsel to issue the legal opinion included in the
Transfer Agent Instructions to the Company's transfer agent on the Effective
Date. The Company agrees that, in the event any Underlying Shares are issued
with a legend in accordance with this Section 3.1(b), it will, within three
Trading Days after request therefor by a Purchaser, provide such Purchaser with
a certificate or certificates representing such Underlying Shares, free from
such legend at such time as such legend would not have been required under this
Section 3.1(b) had such issuance occurred on the date of such request. The
Company may not make any notation on its records or give instructions to any
transfer agent of the Company which enlarge the restrictions of transfer set
forth in this Section.

    3.2 Acknowledgment of Dilution. The Company acknowledges that the issuance
of the Underlying Shares upon (i) conversion of the Debentures and (ii) exercise
of the Warrants will result in dilution of the outstanding shares of Common
Stock, which dilution may be substantial under certain market conditions. The
Company further acknowledges that its obligation to issue Underlying Shares upon
(x) conversion of the Debentures and (y) exercise of the Warrants is
unconditional and absolute, subject to the limitations set forth in the
Debentures or in the Warrants, regardless of the effect of any such dilution.

                                       12

<PAGE>   14

    3.3 Furnishing of Information. As long as the Purchasers own Securities, the
Company covenants to timely file (or obtain extensions in respect thereof and
file within the applicable grace period) all reports required to be filed by the
Company after the date hereof pursuant to Section 13(a) or 15(d) of the Exchange
Act. As long as the Purchasers own Securities, if the Company is not required to
file reports pursuant to such sections, it will prepare and furnish to the
Purchasers and make publicly available in accordance with Rule 144(c)
promulgated under the Securities Act such information as is required for the
Purchasers to sell the Securities under Rule 144 promulgated under the
Securities Act. The Company further covenants that it will take such further
action as any holder of Securities may reasonably request, all to the extent
required from time to time to enable such Person to sell Underlying Shares
without registration under the Securities Act within the limitation of the
exemptions provided by Rule 144 promulgated under the Securities Act, including
causing its attorneys to render and deliver any legal opinion required in order
to permit a Purchaser to sell Underlying Shares under Rule 144 upon notice of an
intention to sell or other form of notice having a similar effect. Upon the
request of any such Person, the Company shall deliver to such Person a written
certification of a duly authorized officer as to whether it has complied with
such requirements.

    3.4 Integration. The Company shall not, and shall use its best efforts to
ensure that no Affiliate of the Company shall, sell, offer for sale or solicit
offers to buy or otherwise negotiate in respect of any security (as defined in
Section 2 of the Securities Act) that could be integrated with the offer or sale
of the Securities in a manner that could require the registration under the
Securities Act of the sale of the Securities to the Purchasers.

    3.5 Increase in Authorized Shares. If on any date the Company could be, if a
notice of conversion or exercise (as the case may be) were to be delivered on
such date, precluded from issuing the sum of (a) 175% of the number of
Underlying Shares as would then be issuable upon a conversion in full of the
Debentures, and (b) the number of Underlying Shares issuable upon exercise in
full of the Warrants (the "Current Required Minimum"), in either case, due to
the unavailability of a sufficient number of authorized but unissued or reserved
shares of Common Stock, then the Board of Directors of the Company shall
promptly prepare and mail to the stockholders of the Company proxy materials
requesting authorization to amend the Company's certificate of incorporation to
increase the number of shares of Common Stock which the Company is authorized to
issue to at least such number of shares as reasonably requested by the
Purchasers in order to provide for such number of authorized and unissued shares
of Common Stock to enable the Company to comply with its issuance, conversion,
exercise and reservation of shares obligations as set forth in this Agreement,
the Debentures and the Warrants (the sum of (x) the number of shares of Common
Stock then outstanding plus all shares of Common Stock issuable upon exercise of
all outstanding options, warrants and convertible instruments, and (y) the
Current Required Minimum, shall be a reasonable number). In connection
therewith, the Board of Directors shall (a) adopt proper resolutions authorizing
such increase, (b) recommend to and otherwise use its best efforts to promptly
and duly obtain stockholder approval to carry out such resolutions (and hold a
special meeting of the stockholders no later than the earlier to occur of (x)
the 25th day after the date on which the Commission shall have indicated that
they approve of or have no further comments on the

                                       13

<PAGE>   15

preliminary proxy materials to be delivered by the Company to its shareholders
in connection with the meeting contemplated by this Section and (y) the 90th day
after request by a holder of a conversion or other issuance that could require
the actions contemplated in this Section) and (c) within two Business Days of
obtaining such stockholder authorization, file an appropriate amendment to the
Company's certificate or articles of incorporation to evidence such increase.

    3.6 Reservation and Listing of Underlying Shares.

         (a) The Company shall (i) in the time and manner required by any
national securities exchange, market, trading or quotation facility on which the
Common Stock is then traded, prepare and file with such national securities
exchange or market or trading or quotation facility on which the Common Stock is
then listed for trading an additional shares listing application covering a
number of shares of Common Stock which is not less than the Current Required
Minimum, (ii) take all steps necessary to cause such shares of Common Stock to
be approved for listing on any such national securities exchange or market or
trading or quotation facility on which the Common Stock is then listed as soon
as possible thereafter, and (iii) provide to the Purchasers evidence of such
listing, and the Company shall maintain the listing of its Common Stock thereon.
If the number of Underlying Shares issuable upon conversion in full of the then
outstanding Debentures and upon exercise of the then unexercised portion of the
Warrants exceeds 85% of the number of Underlying Shares previously listed on
account thereof with any such required exchanges, then the Company shall take
the necessary actions to list immediately a number of Underlying Shares as
equals no less than the then Current Required Minimum.

         (b) The Company shall maintain a reserve of shares of Common Stock for
issuance upon conversion of the Debentures in full and upon exercise in full of
the Warrants in accordance with this Agreement, the Debentures and the Warrants,
respectively, in such amount as may be required to fulfill its obligations in
full under the Transaction Documents, which reserve shall equal no less than the
then Current Required Minimum.

    3.7 Conversion and Exercise Procedures. The Transfer Agent Instructions,
Conversion Notice (as defined in the Debentures) and Form of Election to
Purchase under the Warrants set forth the totality of the procedures with
respect to the conversion of the Debentures and exercise of the Warrants,
including the form of legal opinion, if necessary, that shall be rendered to the
Company's transfer agent and such other information and instructions as may be
reasonably necessary to enable the Purchasers to convert their Debentures and
exercise their Warrants.

    3.8 Conversion and Exercise Obligations of the Company. The Company shall
honor conversions of the Debentures and exercises of the Warrants and shall
deliver Underlying Shares in accordance with the respective terms, conditions
and time periods set forth in the Debentures and the Warrants.

    3.9 Right of First Refusal; Participation Right; Subsequent Registrations.

         (a) Commencing on the date hereof and for a period of 120-Trading Days
after the Effective Date, provided that such 120-Trading Day period shall be
extended for the number of Trading Days during such period (A) in which trading
in the Common Stock is suspended by The Nasdaq Stock Market or such market or
quotation system on which the Common Stock is then listed, or (B) during which
the Underlying Shares Registration Statement is not effective, or (C) during
which the prospectus included in the Underlying Shares Registration Statement
may not be used by the holders thereof for the resale of Underlying Shares (the
"Investment Restriction Period"), the Purchasers shall have the right to
co-invest (the "Co-Investment Right") on the same terms and conditions in any
transaction intended to be exempt or not subject to registration under the
Securities Act in which the Company shall, directly or indirectly, offer, sell,
grant any option to purchase, or otherwise dispose of (or announce any offer,
sale or grant of any option to purchase or otherwise dispose of) any of its or
its Affiliates' equity or equity-equivalent securities, including the issuance
of any debt or other instrument at any time over the life thereof convertible
into or exchangeable for Common Stock (a "Subsequent Placement").
Notwithstanding the foregoing, the following transactions shall not constitute a
Subsequent Placement: (i) the issuance of shares of Common Stock upon conversion
of the Debentures or upon the exercise of the Warrants in accordance with their
respective terms; (ii) the issuance of shares of Common Stock upon the exercise
of outstanding options or warrants to purchase shares of Common Stock; (iii) the
issuance of any options or warrants to purchase Common Stock to employees,
officers or directors of, or consultants to, the Company pursuant to any stock
option or stock purchase plan or agreements approved by the Company's Board of
Directors; (iv) the issuance of shares of Common Stock or securities convertible
into or exchangeable for shares of Common Stock to any bank lender (including
the issuance of warrants contemplated on Schedule 2.1(c) hereto as item (4)
under the section titled "Options and Warrants") or other Person in satisfaction
of amounts owing to such Person; or (v) the issuance of shares of Common Stock
or options or warrants to purchase Common Stock pursuant to the Cereus Merger.
The Company shall give promptly to the Purchasers written notice of any
Subsequent Placement, which notice shall describe in reasonable detail the
proposed terms of such Subsequent Placement (the "Subsequent Placement Notice").
The Purchasers' Co-Investment Right shall terminate unless the Purchasers notify
the Company of their intention to purchase the securities proposed to be sold in
the Subsequent Placement on the terms set forth in the Subsequent Placement
Notice by 6:30 p.m. New York City time by the seventh Trading Day after their
receipt of such Subsequent Placement Notice. The Co-Investment Right shall be
allocated among the Purchasers on a pro rata basis by reference to aggregate
principal amount of the Debentures purchased by such Purchaser under this
Agreement, or in such other manner as the Purchasers shall determine.

         (b) Notwithstanding anything to the contrary contained herein, if a
Subsequent Placement provides for the (i) sale of shares of Common Stock at a
per share purchase price less than 85% of the fair market value of such shares
on the date of sale, and/or (ii) sale of any security convertible into or
exchangeable for shares of Common Stock including any securities which provide
for any adjustments to the conversion or exchange ratio (including "reset"
provisions), as the case may be (other than adjustments occasioned by stock
dividends or a

                                       15
<PAGE>   17

combination, subdivision or reclassification of outstanding shares of Common
Stock) ("First Refusal Convertible Securities"), and the per share purchase
price to be paid for the Common Stock issuable pursuant to such First Refusal
Convertible Securities is, or could be, less than 85% of the fair market value
of such shares on the date the First Refusal Convertible Security is first
issued, then, and in such event, the Purchasers shall have a right of first
refusal with respect to such financing and the Subsequent Placement Notice shall
describe in reasonable detail the proposed terms of such Subsequent Placement,
the amount of proceeds intended to be raised thereunder, the Person with whom
such Subsequent Placement is proposed to be effected and shall annex thereto the
proposed form of documentation. The Purchasers shall notify the Company by 6:30
p.m. New York City time by the seventh Trading Day after its receipt of the
Subsequent Placement Notice of its willingness to provide (or to cause its
designee to provide), in accordance with the terms set forth in the Subsequent
Placement Notice and pursuant to the proposed form of documentation (subject to
reasonable modifications), financing to the Company. If the Purchasers notify
the Company of their willingness to provide the proposed financing, the parties
shall act and negotiate in good faith to cause a closing of the proposed
financing to be effected on or before the twelfth Trading Day after the
Purchasers receipt of the Subsequent Placement Notice. Commencing upon its
delivery of the Subsequent Placement Notice, the Company shall act in good faith
and shall provide Purchasers with timely responses to any business inquiries
necessary for its evaluation of the proposed financing. Further, commencing upon
its delivery of the Subsequent Placement Notice, the Company shall act in good
faith, and shall cause its legal and accounting professionals to act in a
commercially reasonable manner, each under the circumstances, to facilitate
closing the proposed financing in a timely manner. The time for closing shall be
extended beyond the twelfth Trading Date after the Purchasers receipt of the
Subsequent Placement Notice by such period of delay which is solely attributable
to the failure of the Company or its professionals to act in the manner
prescribed by the foregoing sentences. If the Purchasers shall fail to notify
the Company of their intention to effect such financing within such time period,
the Company may effect such Subsequent Placement substantially upon the terms
and to the Persons (or Affiliates of such Persons) set forth in the Subsequent
Placement Notice; provided that the Company shall provide the Purchasers with a
second Subsequent Placement Notice, and the Purchasers shall again have the
right of first refusal set forth above in this paragraph (b), if the Subsequent
Placement subject to the initial Subsequent Placement Notice shall not have been
consummated for any reason on the terms set forth in such Subsequent Placement
Notice within thirty Trading Days after the date of the initial Subsequent
Placement Notice with the Person (or an Affiliate of such Person) identified in
the Subsequent Placement Notice. If the Purchasers shall indicate a willingness
to provide financing in excess of the amount set forth in the Subsequent
Placement Notice, then each Purchaser shall be entitled to provide financing
pursuant to such Subsequent Placement Notice up to an amount equal to such
Purchaser's pro-rata portion of the aggregate principal amount of Debentures
purchased by such Purchaser under this Agreement, but the Company shall not be
required to accept financing from the Purchasers in an amount less than or in
excess of the aggregate amount set forth in the Subsequent Placement Notice.

         (c) Except as set forth on Schedule 3.9(c), the Company shall not for a
period of 60-Trading Days after the Effective Date, provided that such
60-Trading Day period shall be extended for the number of Trading Days during
such period (A) in which trading in the

                                       16
<PAGE>   18

Common Stock is suspended by The Nasdaq Stock Market or such market or quotation
system on which the Common Stock is then listed, or (B) during which the
Underlying Shares Registration Statement is not effective, or (C) during which
the prospectus included in the Underlying Shares Registration Statement may not
be used by the holders thereof for the resale of Underlying Shares (the
"Registration Restriction Period", without the prior written consent of the
Purchasers, permit to be filed a registration statement which seeks to register
"Discount Shares" (as hereinafter defined). Notwithstanding the foregoing, on or
after the tenth Trading Day preceding the expiration of the Registration
Restriction Period the Company may file a registration statement covering
Discount Shares, provided that such registration statement shall not be declared
effective by the SEC prior to the expiration of the Registration Restriction
Period. The term "Discount Shares" shall mean (i) Common Stock, the purchase
price per share of which on the date of sale was less than 75% of the fair
market value of such shares on such date, or (ii) First Refusal Convertible
Securities where the purchase price to be paid for the Common Stock issuable
pursuant to such First Refusal Convertible Securities is, or could be, less than
75% of the fair market value of such shares on the date the First Refusal
Convertible Security was first issued.

    3.10 Certain Securities Laws Disclosures; Publicity. The Company shall: (i)
on the Initial Closing Date, issue a press release reasonably acceptable to the
Purchasers disclosing the transactions contemplated hereby, (ii) file with the
Commission a Report on Form 8-K disclosing the transactions contemplated hereby
within ten Business Days after the Initial Closing Date (including this
Agreement, the form of Warrant and the Registration Rights Agreement as exhibits
thereto), and (iii) timely file with the Commission a Form D promulgated under
the Securities Act as required under Regulation D promulgated under the
Securities Act and provide a copy thereof to the Purchasers promptly after the
filing thereof. The Company shall, no less than one Business Day prior to the
filing of any disclosure required by clauses (ii) and (iii) above, provide a
copy thereof to the Purchasers. Such filings will not be made without the
consent of the Purchasers, not to be unreasonably withheld or delayed. The
Company and the Purchasers shall consult with each other in issuing any other
press releases or otherwise making public statements or filings and other
communications with the Commission or any regulatory agency or stock market or
trading facility with respect to the transactions contemplated hereby, and
neither party shall issue any such press release or otherwise make any such
public statement, filings or other communications without the prior written
consent of the other, which consent shall not be unreasonably withheld or
delayed, except that no prior consent shall be required if such disclosure is
required by law or stock market regulations, in which such case the disclosing
party shall provide the other party with prior notice of such public statement,
filing or other communication.

    3.11 Use of Proceeds. The Company shall use the net proceeds from the sale
of the Securities hereunder for the repayment of debt incurred under the PNC
Agreement and for working capital purposes and not for the satisfaction of any
portion of the Company's debt (other than pursuant to the PNC Agreement and
payment of (a) trade payables in the ordinary course of the Company's business
and consistent with prior practices or (b) capital lease obligations).

                                       17
<PAGE>   19

    3.12 Reimbursement. If any Purchaser, other than by reason of its gross
negligence or willful misconduct, becomes involved in any capacity in any
action, proceeding or investigation brought by or against any Person, including
stockholders of the Company, in connection with or as a result of the
consummation of the transactions contemplated by Transaction Documents, the
Company will reimburse such Purchaser for its reasonable legal and other
expenses (including the reasonable cost of any investigation and preparation and
travel in connection therewith) incurred in connection therewith, as such
expenses are incurred. In addition, other than with respect to any matter in
which a Purchaser is a named party, the Company will pay such Purchaser the
charges, as reasonably determined by such Purchaser, for the time of any
officers or employees of such Purchaser devoted to appearing and preparing to
appear as witnesses, assisting in preparation for hearings, trials or pretrial
matters, or otherwise with respect to inquiries, hearings, trials, and other
proceedings relating to the subject matter of this Agreement. The reimbursement
obligations of the Company under this paragraph shall be in addition to any
liability which the Company may otherwise have, shall extend upon the same terms
and conditions to any Affiliates of the Purchasers who are actually named in
such action, proceeding or investigation, and partners, directors, agents,
employees and controlling persons (if any), as the case may be, of the
Purchasers and any such Affiliate, and shall be binding upon and inure to the
benefit of any successors, assigns, heirs and personal representatives of the
Company, the Purchasers and any such Affiliate and any such Person. The Company
also agrees that neither the Purchasers nor any such Affiliates, partners,
directors, agents, employees or controlling persons shall have any liability to
the Company or any Person asserting claims on behalf of or in right of the
Company in connection with or as a result of the consummation of the Transaction
Documents except to the extent that any losses, claims, damages, liabilities or
expenses incurred by the Company result from the gross negligence or willful
misconduct of the applicable Purchaser or entity in connection with the
transactions contemplated by this Agreement.

    3.13 Certain Trading Restrictions. (a) Each Purchaser agrees that it will
not enter into and will not encourage or assist others into entering on its
behalf into any Short Sales (as hereinafter defined) or have other Persons do so
on their behalf for so long as its holds Debentures. For purposes hereof, a
"Short Sale" by a Purchaser shall mean a sale of Common Stock by a Purchaser
that is marked as a short sale and that is made at a time when there is no
equivalent offsetting long position in the Common Stock held by such Purchaser.
For purposes of determining whether there is an equivalent offsetting long
position in the Common Stock held by a Purchaser, on any date of computation,
Underlying Shares that would be issuable upon the conversion in full of the
Debentures or exercise in full of the Warrants held by such Purchaser shall be
deemed to be held long by such Purchaser.

         (b) The Company shall not issue or sell any of the principal amount of
the Debentures to any Person other than the Purchasers.

    3.14 No Dividends. So long as any amount remains outstanding under any
Debenture, the Company shall not pay any dividend on account of any outstanding
capital stock, except dividends paid in shares of the Company's capital stock.

    3.15 Adjustment to Exchange Ratio. In the event that at any time prior to
the Third Closing Date the Exchange Ratio (as defined in the Merger Agreement)
is modified such that each share of Cereus Common Stock (as defined in the
Merger Agreement) issued and outstanding immediately prior to the Effective Time
(as defined in the Merger Agreement) shall be converted into the right to
receive, without interest, more than 1.75 fully paid and non-assessable shares
of Parent Common Stock (as defined in the Merger Agreement), then the Conversion
Price shall be decreased proportionately as follows:
                    PX
         CP= X+((CN)-- (CO))

Where:
         CP= New Conversion Price;

         P= $4.80;

         X= 41,606,823;

         C= 9,023,444;

         O= 1.75; and

         N= The new Exchange Ratio.

amended except in a written instrument signed, in the case of an amendment, by
the Company and each of the Purchasers or, in the case of a waiver, by the party
against whom enforcement of any such waiver is sought. No waiver of any default
with respect to any provision, condition or requirement of this Agreement shall
be deemed to be a continuing waiver in the future or a waiver of any other
provision, condition or requirement hereof, nor shall any delay or omission of
either party to exercise any right hereunder in any manner impair the exercise
of any such right accruing to it thereafter.

    5.5 Headings. The headings herein are for convenience only, do not
constitute a part of this Agreement and shall not be deemed to limit or affect
any of the provisions hereof.

    5.6 Successors and Assigns. This Agreement shall be binding upon and inure
to the benefit of the parties and their successors and permitted assigns. The
Company may not assign this Agreement or any rights or obligations hereunder
without the prior written consent of the Purchasers.

    5.7 No Third-Party Beneficiaries. This Agreement is intended for the benefit
of the parties hereto and their respective successors and permitted assigns and
is not for the benefit of, nor may any provision hereof be enforced by, any
other Person.

    5.8 Governing Law. The corporate laws of the State of Minnesota shall govern
all issues concerning the relative rights of the Company and its stockholders.
All other questions concerning the construction, validity, enforcement and
interpretation of the Transaction Documents shall be governed by and construed
and enforced in accordance with the internal laws of the State of New York,
without regard to the principles of conflicts of law thereof. Each party hereby
irrevocably submits to the exclusive jurisdiction of the state and federal
courts sitting in the City of New York, borough of Manhattan, for the
adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein (including with respect to
the enforcement of the any of the Transaction

                                       24
<PAGE>   26

Documents), and hereby irrevocably waives, and agrees not to assert in any suit,
action or proceeding, any claim that it is not personally subject to the
jurisdiction of any such court, that such suit, action or proceeding is
improper. Each party hereby irrevocably waives personal service of process and
consents to process being served in any such suit, action or proceeding by
mailing a copy thereof via registered or certified mail or overnight delivery
(with evidence of delivery) to such party at the address in effect for notices
to it under this Agreement and agrees that such service shall constitute good

permitted by law.

    5.9 Survival. The representations, warranties, agreements and covenants
contained herein shall survive the Closing and the delivery, exercise and

of three years from the last Closing Date.

    5.10 Execution. This Agreement may be executed in two or more counterparts,
all of which when taken together shall be considered one and the same agreement
and shall become effective when counterparts have been signed by each party and
delivered to the other party, it being understood that both parties need not
sign the same counterpart. In the event that any signature is delivered by
facsimile transmission, such signature shall create a valid and binding
obligation of the party executing (or on whose behalf such signature is
executed) the same with the same force and effect as if such facsimile signature
page were an original thereof.

    5.11 Severability. In case any one or more of the provisions of this
Agreement shall be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Agreement shall not
in any way be affected or impaired thereby, and the parties will attempt to
agree upon a valid and enforceable provision which shall be a reasonable
substitute therefor, and upon so agreeing, shall incorporate such substitute
provision in this Agreement.

    5.12 Remedies. In addition to being entitled to exercise all rights provided
herein or granted by law, including recovery of damages, each of the Purchasers
will be entitled to specific performance of the obligations of the Company under
the Transaction Documents. The Company and each of the Purchasers agree that
monetary damages may not be adequate compensation for any loss incurred by
reason of any breach of its obligations described in the foregoing sentence and
hereby agrees to waive in any action for specific performance of any such
obligation the defense that a remedy at law would be adequate.

    5.13 Independent Nature of Purchasers' Obligations and Rights. The
obligations of each Purchaser under any Transaction Document is several and not
joint with the obligations of any other Purchaser, and no Purchaser shall be
responsible in any way for the performance of the obligations of any other
Purchaser under any Transaction Document. Nothing contained herein or in any
Transaction Document, and no action taken by any Purchaser pursuant thereto,
shall be deemed to constitute the Purchasers as a partnership, an association, a
joint venture or any other kind of entity, or create a presumption that the
Purchasers are in any way

                                       25
<PAGE>   27

acting in concert with respect to such obligations or the transactions
contemplated by the Transaction Document. Each Purchaser shall be entitled to
independently protect and enforce its rights, including without limitation the
rights arising out of this Agreement or out of the other Transaction Documents,
and it shall not be necessary for any other Purchaser to be joined as an
additional party in any proceeding for such purpose.

arrangement of the Company in an amount exceeding five hundred thousand dollars

               (vii)  an Underlying Shares Registration Statement shall not have
been declared effective by the Commission (as defined in Section 6) on or prior
to the 175th day after the Original Issue Date;

               (viii) if, during the Effectiveness Period (as defined in the
Registration Rights Agreement (as defined in Section 8)), the effectiveness of
the Underlying Shares Registration Statement lapses for any reason or the Holder
shall not be permitted to resell Registrable Securities (as defined in the
Registration Rights Agreement) under an Underlying Shares Registration
Statement, in either case, for an aggregate of more of than sixty Trading Days
(which need not be consecutive Trading Days) in any twelve month period;

               (ix)   an Event (as defined in the Registration Rights Agreement)
shall not have been cured to the reasonable satisfaction of the Holder prior to
the expiration of thirty days from the Event Date (as defined in the

               (x)    the Company shall fail for any reason to deliver
certificates to a Holder prior to the seventh (7th) Trading Day after a Delivery
Date (as defined in Section 4(e)) pursuant to and in accordance with Section
4(b) or the Company shall provide notice to the Holder, including by way of
public announcement, at any time, of its intention not to comply with requests
for conversions of any Debentures in accordance with the terms hereof; or

               (xi)   the Company shall fail for any reason to deliver the
payment in cash pursuant to a Buy-In (as defined herein) within five Business
Days after written notice for such Buy-In is provided.

         (b)   If any Event of Default occurs, the full principal amount of this
Debenture (and, at the Holder's option, all other Debentures then held by such
Holder), together with interest and other amounts owing in respect thereof, to
the date of acceleration shall become, at the Holder's election immediately due
and payable in cash. The aggregate amount payable upon an Event of Default shall
be equal to the sum of (i) the Mandatory Prepayment Amount (as defined in
Section 7) plus (ii) the product of (A) the number of Underlying Shares issued
in respect of conversions hereunder within thirty (30) days of the date of a
declaration of an Event of Default and then held by the Holder and (B) the
closing sales price of the Common Stock as reported by Bloomberg L.P. (or the
successor to its function of reporting share prices) on the date prepayment is
due or the date the full prepayment price is paid, whichever is greater.
Interest shall accrue on the prepayment amount hereunder from the seventh
Business Day after such amount is due (being the date of an Event of Default)
through the date of prepayment in full thereof at the rate of 18% per annum (or
such lesser maximum amount that is permitted to be paid by applicable law), to
accrue daily from the date such payment is due hereunder through and including
the date of payment. All Debentures and Underlying Shares for which the full
prepayment price hereunder shall have been paid in accordance herewith shall
promptly be surrendered to or as

                                       4

directed by the Company. The Holder need not provide and the Company hereby
waives any presentment, demand, protest or other notice of any kind, and the
Holder may immediately enforce any and all of its rights and remedies hereunder
and all other remedies available to it under applicable law. Such declaration
may be rescinded and annulled by Holder at any time prior to payment hereunder.
No such rescission or annulment shall affect any subsequent Event of Default or
impair any right consequent thereon.

    Section 4. Conversion.

         (a)   Conversion at Option of Holder. The Holder shall effect
conversions hereunder by delivering to the Company by facsimile a completed
conversion notice in the form attached as Exhibit A (a "Holder Conversion
Notice") and delivery to the Company within two Trading Days thereafter of the
principal amount of Debentures to be converted. Each Holder Conversion Notice
shall specify the date on which such conversion is to be effected, which date
may not be prior to the date such Holder Conversion Notice is deemed to have
been delivered hereunder (a "Holder Conversion Date"). If no Holder Conversion
Date is specified in a Holder Conversion Notice, the Holder Conversion Date
shall be the date that such Holder Conversion Notice is deemed delivered
hereunder. Subject to Section 4(b), each Holder Conversion Notice, once given,
shall be irrevocable. If the Holder is converting less than all of the principal
amount represented by the Debenture(s) tendered by the Holder with the Holder
Conversion Notice, or if a conversion hereunder cannot be effected in full for
any reason, the Company shall honor such conversion to the extent permissible
hereunder and shall promptly deliver to such Holder (in the manner and within
the time set forth in Section 4(e)) a new Debenture for such principal amount as
has not been converted.

         (b)   Conversion at Option of the Company.

               (i)   If the conditions set forth in this subsection are
satisfied, the Company may require the conversion of all or a portion of the
principal amount of the Debentures subject to an effective Underlying Shares
Registration Statement. The Company shall only have the right to require
conversions hereunder if (i) the closing sales price of the Common Stock as
reported by Bloomberg L.P. (or any successor to its function of reporting share
prices) exceeds $6.72 (subject to equitable adjustment in the event of stock
splits and similar events) for twenty consecutive Trading Days following the
date on which an Underlying Shares Registration Statement shall have first been
declared effective by the Securities and Exchange Commission (the "Effective
Date"), (ii) the Underlying Shares Registration Statement shall be effective and
the prospectus thereunder available to the Holders for the resale of all
Underlying Shares issuable upon such conversion during the entire twenty Trading
Day period and on the Company Conversion Date (as defined below) or Underlying
Shares may be sold by the Holder subject to such conversion without volume
limitation under Rule 144(k) promulgated under the Securities Act on the Company
Conversion Date, (iii) the Company has available sufficient unreserved and
available shares of Common Stock to fulfill its share delivery requirements upon
such conversion, (iv) the Common Stock is listed or quoted for trading on the
NASDAQ or a Subsequent Market during the entire twenty Trading Day calculation
period described above in this subsection, (v) such conversion would not result

                                       5

<PAGE>   36

in a violation of Section 4d(i), (ii) or (iii), and (vi) the Company shall not
have been more than three Trading Days late in delivering any conversion shares
pursuant to Section 4(e).

               (ii)  The Company shall exercise its right to require conversions
under Section 4(b)(i) by delivering to the Holder a completed conversion notice
in the form attached as Exhibit B (a "Company Conversion Notice"). Each of a
Company Conversion Notice and a Holder Conversion Notice is sometimes referred
to herein as a "Conversion Notice". Each Company Conversion Notice shall specify
the principal amount of Debentures to be converted and the date on which such
conversion is to be effected, which date may not be prior to the date such
Company Conversion Notice is deemed to have been delivered hereunder (a "Company
Conversion Date"). Each of a Company Conversion Date and a Holder Conversion
Date is referred to herein as a "Conversion Date". If no Conversion Date is
specified in a Company Conversion Notice, the Conversion Date shall be the date
that such Company Conversion Notice is deemed delivered hereunder. Subject to
the Holder's rights under Section 4(b), the conversion subject to each Company
Conversion Notice, once given, shall be irrevocable. Not more than three Trading
Days following receipt of the Company Conversion Notice, the Holder shall
deliver to the Company the principal amount of Debentures subject to such
Company Conversion Notice against receipt of the Underlying Shares. If the
Company is requiring conversion of less than the full principal amount
represented by the Debenture(s) tendered by the Holder following a Company
Conversion Notice, or if a conversion hereunder cannot be effected in full for
any reason, the Company shall honor such conversion to the extent permissible
hereunder and shall promptly deliver to such Holder (in the manner and within
the time set forth in Section 4(e)) a new Debenture for such principal amount as
has not been converted.

         (c) Number of Underlying Shares Issuable Upon Conversion.

               (i)   The number of shares of Common Stock issuable upon a
conversion hereunder shall be determined by adding the sum of (i) the quotient
obtained by dividing (x) the principal amount of this Debenture to be converted
and (y) the Conversion Price (as defined herein), and (ii) the amount equal to
(I) the product of (x) the principal amount of this Debenture to be converted
and (y) the product of (1) .000139 and (2) the number of days for which such
principal amount was outstanding, divided by (II) the Conversion Price on the
Conversion Date, provided, that (1) if the Company shall have paid the interest
at issue in cash, subsection (ii) shall not be used in the calculation of the
number of shares of Common Stock issuable upon such conversion, and (2) only
such portion of the accrued and outstanding amount of interest owing on the
principal amount being converted shall be calculated in subsection (ii), giving
credit for previously paid interest on such principal amount.

               (ii)  Notwithstanding anything to the contrary contained herein,
if on any Conversion Date: (1) the number of shares of Common Stock at the time
authorized, unissued and unreserved for all purposes, or held as treasury stock,
is insufficient to permit issuance of the shares upon Conversion; (2) after the
Effective Date (as defined in Section 7) such shares of Common Stock (x) are not
registered for resale pursuant to an effective

                                       6

<PAGE>   37

Underlying Shares Registration Statement and (y) may not be sold without volume
restrictions pursuant to Rule 144(k) promulgated under the Securities Act (as
defined in Section 7), as determined by counsel to the Company pursuant to a
written opinion letter, addressed to the Company's transfer agent in the form
and substance reasonably acceptable to the applicable Holder and such transfer
agent; (3) the Common Stock is not listed or quoted for trading on the NASDAQ or
on a Subsequent Market; or (4) the issuance of such shares of Common Stock would
result in a violation of Sections 4(d)(i), (ii) or (iii), then, at the option of
the Holder, the Company, in lieu of delivering shares of Common Stock pursuant
to Section 4(c), shall deliver, within ten Trading Days of each applicable
Conversion Date, an amount in cash equal to the product of (a) the outstanding
principal amount of the Debentures to be converted on such Conversion Date and
(b) the product of (x) .000139 and (y) the number of days for which such
principal amount was outstanding, less any interest previously paid in cash.

         (d)   Certain Conversion Restrictions.

               (i)   A Holder may not convert Debentures to the extent such
conversion would result in the Holder, together with any affiliate thereof,
beneficially owning (as determined in accordance with Section 13(d) of the
Exchange Act and the rules promulgated thereunder) in excess of 4.999% of the
then issued and outstanding shares of Common Stock, including shares issuable
upon conversion of the Debentures held by such Holder after application of this
Section. Since the Holder will not be obligated to report to the Company the
number of shares of Common Stock it may hold at the time of a conversion
hereunder, unless the conversion at issue would result in the issuance of shares
of Common Stock in excess of 4.999% of the then outstanding shares of Common
Stock without regard to any other shares which may be beneficially owned by the
Holder or an affiliate thereof, the Holder shall have the authority and
obligation to determine whether the restriction contained in this Section will
limit any particular conversion hereunder and to the extent that the Holder
determines that the limitation contained in this Section applies, the
determination of which portion of the principal amount of Debentures are
convertible shall be the responsibility and obligation of the Holder. If the
Holder has delivered a Conversion Notice for a principal amount of Debentures
that, without regard to any other shares that the Holder or its affiliates may
beneficially own, would result in the issuance in excess of the permitted amount
hereunder, the Company shall notify the Holder of this fact and shall honor the
conversion for the maximum principal amount permitted to be converted on such
Conversion Date in accordance with the periods described in Section 4(b) and, at
the option of the Holder, either retain any principal amount tendered for
conversion in excess of the permitted amount hereunder for future conversions or
return such excess principal amount to the Holder. The provisions of this
Section may be waived by a Holder (but only as to itself and not to any other
Holder) upon not less than sixty-one days prior notice to the Company. Other
Holders shall be unaffected by any such waiver.

               (ii)  A Holder may not convert Debentures to the extent such
conversion would result in the Holder, together with any affiliate thereof,
beneficially owning (as determined in accordance with Section 13(d) of the
Exchange Act and the rules promulgated thereunder) in excess of 9.999% of the
then issued and outstanding shares of

                                       7

<PAGE>   38

Common Stock, including shares issuable upon conversion of the Debentures held
by such Holder after application of this Section. Since the Holder will not be
obligated to report to the Company the number of shares of Common Stock it may
hold at the time of a conversion hereunder, unless the conversion at issue would
result in the issuance of shares of Common Stock in excess of 9.999% of the then
outstanding shares of Common Stock without regard to any other shares which may
be beneficially owned by the Holder or an affiliate thereof, the Holder shall
have the authority and obligation to determine whether the restriction contained
in this Section will limit any particular conversion hereunder and to the extent
that the Holder determines that the limitation contained in this Section
applies, the determination of which portion of the principal amount of
Debentures are convertible shall be the responsibility and obligation of the
Holder. If the Holder has delivered a Conversion Notice for a principal amount
of Debentures that, without regard to any other shares that the Holder or its
affiliates may beneficially own, would result in the issuance in excess of the
permitted amount hereunder, the Company shall notify the Holder of this fact and
shall honor the conversion for the maximum principal amount permitted to be
converted on such Conversion Date in accordance with the periods described in
Section 4(b) and, at the option of the Holder, either retain any principal
amount tendered for conversion in excess of the permitted amount hereunder for
future conversions or return such excess principal amount to the Holder. The
provisions of this Section may be waived by a Holder (but only as to itself and
not to any other Holder) upon not less than sixty-one days prior notice to the
Company. Other Holders shall be unaffected by any such waiver.

               (iii) If the Common Stock is then listed for trading on the
NASDAQ National Market or the Nasdaq SmallCap Market and the Company has not
obtained the Shareholder Approval (as defined below), then the Company is
precluded from issuing at a Conversion Price or, with respect to the Warrants
described below in this sentence, an exercise price, that is less than the
closing sales price per share of the Common Stock on the Trading Day immediately
preceding the first closing of the transactions contemplated by the Purchase
Agreement, subject to equitable adjustment in the event of stock splits and
similar events (such price, the "Market Price"), in excess of 5,160,577 shares
of Common Stock (the "Issuable Maximum") upon conversion of the Debentures and
exercise of the Warrants (as defined in the Purchase Agreement). The Issuable
Maximum equals 19.999% of the number of shares of Common Stock outstanding
immediately prior to the first closing of transactions set forth in the Purchase
Agreement. Accordingly, if on any Conversion Date (A) the Common Stock is listed
for trading on the NASDAQ or the Nasdaq SmallCap Market and (B) the Company
shall not have previously obtained the vote of shareholders (the "Shareholder
Approval"), if any, as may be required by the applicable rules and regulations
of the Nasdaq Stock Market (or any successor entity) applicable to approve the
issuance of a number of shares of Common Stock in excess of the Issuable Maximum
at a price below the Market Price, then the Company shall issue to the Holder
requesting a conversion a number of shares of Common Stock equal to the lesser
of (x) the number of shares of Common Stock issuable upon such conversion at the
Conversion Price and (y) the Issuable Maximum less all shares of Common Stock
previously issued upon conversion of the Debentures and as payment of interest
thereon (but only those shares issued at a Conversion Price less than the Market
Price) and all shares of Common Stock previously issued upon any exercise of
Warrants (but only those shares issued at an

                                       8

<PAGE>   39

exercise price less than the Market Price). With respect to the principal amount
of Debentures tendered for conversion at issue for which a conversion in
accordance with the Conversion Price would, when aggregated with all shares of
Common Stock previously issued on account of conversions of Debentures and
payment of interest thereon and upon exercise of Warrants (at the exercise and
Conversion Price described in the immediately preceding sentence) (the "Excess
Principal"), result in the issuance of a number of shares of Common Stock in
excess of the Issuable Maximum, the converting Holder shall have the option to
require the Company to either (1) use its best efforts to obtain the Shareholder
Approval applicable to such issuance as soon as is possible, but in any event
not later than the first to occur of (x) the twenty-fifth day from the date that
the Commission approves or indicates that it has no further comments to the
Company's preliminary proxy statement, if any, prepared for delivery to the
shareholders of the Company in connection with the Shareholder Approval
contemplated hereby and (y) the 90th day after such request (such date the
"Approval Date"), or (2) pay cash to the converting Holder in an amount equal to
the Mandatory Prepayment Amount for the Excess Principal. If the converting
Holder shall have elected the first option pursuant to the immediately preceding
sentence and the Company shall have failed for any reason to obtain the
Shareholder Approval on or prior to the Approval Date, then within three days of
the Holder's demand therefore, which may be given at any time following the
Approval Date, the Company shall pay cash to the converting Holder in an amount
equal to the Mandatory Prepayment Amount for the Excess Principal. If the
Company fails to pay the Mandatory Prepayment Amount in full pursuant to this
Section within seven days of the date payable, the Company will pay interest
thereon at a rate of 18% per annum (or such lesser maximum amount that is
permitted to be paid by applicable law) to the converting Holder, accruing daily
from the Conversion Date until such amount, plus all such interest thereon, is
paid in full. In the event there is more than one holder of Debentures, the
Issuable Maximum applicable to each Debenture shall be determined pro rata by
reference to the percentage of the principal amount of all Debentures held by
such Holder, provided that if one or more Debentures shall have been prepaid or
converted without having been issued its pro rata allocated portion of the
Issuable Maximum such unissued shares shall be allocated pro rata to the
remaining Holders. It is understood and agreed that shares of Common Stock
delivered to and held by the Holder or one of its affiliates on account of
conversion hereunder may not cast votes on the matter of Shareholder Approval.
Shares delivered on account of conversion hereunder and not held by the Holder
or its affiliates may cast votes on the matter of Shareholder Approval. Any
Mandatory Prepayment Amount owing pursuant to this Section shall be due and
payable by the 20th day following the demand therefor.

         (e)   Delivery of Certificates.

               (i)   Not later than three Trading Days after any Conversion Date
(a "Delivery Date"), the Company will deliver to the Holder (A) a certificate or
certificates which shall be free of restrictive legends and trading restrictions
(other than those required by Section 3.1(b) of the Purchase Agreement or in the
event that the Holder does not execute and deliver to the Company by fax the
undertaking set forth in the Company Conversion Notice within two Trading Days
after a Company Conversion Date (provided that in such event, the Company shall
cause any legend to be removed immediately upon receipt of such undertaking))

representing the number of shares of Common Stock being acquired upon the
conversion of Debentures, (B) Debentures in a principal amount equal to the
principal amount of Debentures not converted, and (C) a bank check in the amount
of accrued and unpaid interest, provided, that the Company shall not be
obligated to issue certificates evidencing the shares of Common Stock issuable
upon conversion of the principal amount of Debentures until Debentures are
delivered for conversion to the Company, or the Holder notifies the Company that
such Debentures have been lost, stolen or destroyed and provides a bond (or
other adequate security) reasonably satisfactory to the Company to indemnify the
Company from any loss incurred by it in connection therewith. The Company shall,
upon request of the Holder, if available, use its best efforts to deliver any
certificate or certificates required to be delivered by the Company under this
Section electronically through the Depository Trust Corporation or another
established clearing corporation performing similar functions. If in the case of
any Conversion Notice such certificate or certificates are not delivered to or
as directed by the applicable Holder by the Delivery Date after a Conversion
Date, the Holder shall be entitled by written notice to the Company at any time
on or before its receipt of such certificate or certificates thereafter, to
rescind such conversion, in which event the Company shall immediately return the
certificates representing the principal amount of Debentures tendered for
conversion.

               (ii)  If the Company fails to deliver to the Holder such
certificate or certificates pursuant to this Section 4 by the Delivery Date, the
Company shall pay to such Holder, in cash, as liquidated damages and not as a
penalty, $5,000 for each Trading Day after the Delivery Date until such
certificates are delivered. Nothing herein shall limit a Holder's right to
pursue actual damages or declare an Event of Default pursuant to Section 3
herein for the Company's failure to deliver certificates representing shares of
Common Stock upon conversion within the period specified herein and such Holder
shall have the right to pursue all remedies available to it at law or in equity
including, without limitation, a decree of specific performance and/or
injunctive relief. The exercise of any such rights shall not prohibit the
Holders from seeking to enforce damages pursuant to any other Section hereof or
under applicable law. Further, if the Company shall not have delivered any cash
due in respect of conversions of Debentures or as payment of interest thereon by
the Delivery Date, the Holder may, by notice to the Company, require the Company
to issue shares of Common Stock pursuant to Section 4(c), except that for such
purpose the Conversion Price applicable thereto shall be the lesser of the
Conversion Price on the Conversion Date and the Conversion Price on the date of
such Holder demand. Any such shares will be subject to the provision of this
Section.

               (iii) In addition to any other rights available to the Holder, if
the Company fails to deliver to the Holder such certificate or certificates
pursuant to this Section 4 by the Delivery Date, and if after the Delivery Date
the Holder purchases (in an open market transaction or otherwise) Common Stock
to deliver in satisfaction of a sale by such Holder of the Underlying Shares
which the Holder anticipated receiving upon such conversion (a "Buy-In"), then
the Company shall pay in cash to the Holder (in addition to any remedies
available to or elected by the Holder) the amount by which (x) the Holder's
total purchase price (including brokerage commissions, if any) for the Common
Stock so purchased exceeds (y) the

                                       10

<PAGE>   41

product of (1) the lesser of (A) the aggregate number of shares of Common Stock
that such Holder anticipated receiving from the conversion at issue or (B) the
number of shares of Common Stock so purchased, multiplied by (2) the Conversion
Price of the Common Stock on the Conversion Date, in which event the number of
shares of Common Stock that would have been issued had the Company timely
complied with its delivery requirements under this Section 4 shall not be so
issued. For example, if the Holder purchases Common Stock having a total
purchase price of $11,000 to cover a Buy-In in connection with an attempted
conversion of Debentures with respect to which the Conversion Price of the
Underlying Shares on the applicable Conversion Date multiplied by the number of
Underlying Shares was equal to $2,000 under clause (A) of the immediately
preceding sentence, the Company shall be required to pay the Holder $9,000. The
Holder shall provide the Company written notice indicating the amounts payable
to the Holder in respect of the Buy-In. Notwithstanding anything contained
herein to the contrary, if a Holder requires the Company to make payment in
respect of a Buy-In for the failure to timely deliver certificates hereunder and
the Company timely pays in full such payment, the Company shall not be required
to pay such Holder liquidated damages under Section 4(e)(ii) in respect of the
certificates resulting in such Buy-In.

         (f)   Conversion Price; Adjustment. The Conversion Price of the
Debentures on any Conversion Date (the "Conversion Price") shall equal $4.80,
subject to adjustment as provided for in subsection (i) through (x) below and in
Section 5 hereof.

               (i)   If the Company, at any time while any Debentures are
         outstanding, (a) shall pay a stock dividend or otherwise make a
         distribution or distributions on shares of its Common Stock or any
         other equity or equity equivalent securities payable in shares of
         Common Stock (other than PIK dividend preferred stock), (b) subdivide
         outstanding shares of Common Stock into a larger number of shares, (c)
         combine (including by way of reverse stock split) outstanding shares of
         Common Stock into a smaller number of shares, or (d) issue by
         reclassification of shares of the Common Stock any shares of capital
         stock of the Company, then the Conversion Price shall be multiplied by
         a fraction of which the numerator shall be the number of shares of
         Common Stock (excluding treasury shares, if any) outstanding before
         such event and of which the denominator shall be the number of shares
         of Common Stock outstanding after such event. Any adjustment made
         pursuant to this Section shall become effective immediately after the
         record date for the determination of stockholders entitled to receive
         such dividend or distribution and shall become effective immediately
         after the effective date in the case of a subdivision, combination or
         re-classification.

               (ii)  If the Company, at any time while any Debentures are
         outstanding, shall issue rights, options or warrants to all holders of
         Common Stock (and not to Holders) entitling them to subscribe for or
         purchase shares of Common Stock at a price per share less than the Per
         Share Market Value at the record date mentioned below, then the
         Conversion Price shall be multiplied by a fraction, of which the
         denominator shall be the number of shares of the Common Stock
         (excluding treasury shares, if any) outstanding on the date of issuance
         of such rights or warrants plus the number of additional shares of
         Common Stock offered for subscription or purchase, and of which

                                       11

<PAGE>   42

         the numerator shall be the number of shares of the Common Stock
         (excluding treasury shares, if any) outstanding on the date of issuance
         of such rights or warrants plus the number of shares which the
         aggregate offering price of the total number of shares so offered would
         purchase at such Per Share Market Value. Such adjustment shall be made
         whenever such rights or warrants are issued, and shall become effective
         immediately after the record date for the determination of stockholders
         entitled to receive such rights, options or warrants. However, upon the
         expiration of any such right, option or warrant to purchase shares of
         the Common Stock the issuance of which resulted in an adjustment in the
         Conversion Price pursuant to this Section, if any such right, option or
         warrant shall expire and shall not have been exercised, the Conversion
         Price shall immediately upon such expiration be recomputed and
         effective immediately upon such expiration be increased to the price
         which it would have been (but reflecting any other adjustments in the
         Conversion Price made pursuant to the provisions of this Section after
         the issuance of such rights or warrants) had the adjustment of the
         Conversion Price made upon the issuance of such rights, options or
         warrants been made on the basis of offering for subscription or
         purchase only that number of shares of the Common Stock actually
         purchased upon the exercise of such rights, options or warrants
         actually exercised.

               (iii) If the Company or any subsidiary thereof, as applicable
         with respect to Common Stock Equivalents (as defined below), at any
         time while Debentures are outstanding shall issue shares of Common
         Stock or rights, warrants, options or other securities or debt that are
         convertible into or exchangeable for shares of Common Stock ("Common
         Stock Equivalents"), entitling any Person to acquire shares of Common
         Stock at a price per share less than the Conversion Price (if the
         holder of the Common Stock or Common Stock Equivalent so issued shall
         at any time, whether by operation of purchase price adjustments, reset
         provisions, floating conversion, exercise or exchange prices or
         otherwise, or due to warrants, options or rights issued in connection
         with such issuance, be entitled to receive shares of Common Stock at a
         price less than the Conversion Price, such issuance shall be deemed to
         have occurred for less than the Conversion Price), then, the Conversion
         Price shall be multiplied by a fraction, the numerator of which shall
         be the number of shares of Common Stock outstanding immediately prior
         to the issuance of such shares of Common Stock or such Common Stock
         Equivalents plus the number of shares of Common Stock which the
         offering price for such shares of Common Stock or Common Stock
         Equivalents would purchase at the Conversion Price, and the denominator
         of which shall be the sum of the number of shares of Common Stock
         outstanding immediately prior to such issuance plus the number of
         shares of Common Stock so issued or issuable, provided, that for
         purposes hereof, all shares of Common Stock that are issuable upon
         conversion exercise or exchange of Common Stock Equivalents shall be
         deemed outstanding immediately after the issuance of such Common Stock
         Equivalents. Such adjustment shall be made whenever such shares of
         Common Stock or Common Stock Equivalents are issued. However, upon the
         expiration of any Common Stock Equivalents the issuance of which
         resulted in an adjustment in the Conversion Price pursuant to this
         Section, if any such Common Stock Equivalents shall expire and shall
         not have been exercised, the

                                       12

<PAGE>   43

         Conversion Price shall immediately upon such expiration be recomputed
         and effective immediately upon such expiration be increased to the
         price which it would have been (but reflecting any other adjustments in
         the Conversion Price made pursuant to the provisions of this Section
         after the issuance of such Common Stock Equivalents) had the adjustment
         of the Conversion Price made upon the issuance of such Common Stock
         Equivalents been made on the basis of offering for subscription or
         purchase only that number of shares of Common Stock actually purchased
         upon the exercise of such Common Stock Equivalents actually exercised.
         The foregoing shall not apply to any (i) issuances of securities as
         consideration in a merger, consolidation or acquisition of assets, or
         in connection with any strategic partnership or joint venture (the
         primary purpose of which is not to raise equity capital), or as
         consideration for the acquisition of a business, product or license by
         the Company, (ii) the issuance of securities upon the exercise or
         conversion of the Company's options, warrants or other convertible
         securities outstanding as of the date hereof, or (iii) the grant of
         options or warrants, or the issuance of additional securities, under
         any duly authorized Company stock option, restricted stock plan or
         stock purchase plan for the benefit of the Company's employees.

               (iv)  If the Company, at any time while Debentures are
         outstanding, shall distribute to all holders of Common Stock (and not
         to Holders) evidences of its indebtedness or assets or rights or
         warrants to subscribe for or purchase any security, then in each such
         case the Conversion Price at which Debentures shall thereafter be
         convertible shall be determined by multiplying the Conversion Price in
         effect immediately prior to the record date fixed for determination of
         stockholders entitled to receive such distribution by a fraction of
         which the denominator shall be the Per Share Market Value determined as
         of the record date mentioned above, and of which the numerator shall be
         such Per Share Market Value on such record date less the then fair
         market value at such record date of the portion of such assets or
         evidence of indebtedness so distributed applicable to one outstanding
         share of the Common Stock as determined by the Board of Directors in
         good faith. In either case the adjustments shall be described in a
         statement provided to the Holders of the portion of assets or evidences
         of indebtedness so distributed or such subscription rights applicable
         to one share of Common Stock. Such adjustment shall be made whenever
         any such distribution is made and shall become effective immediately
         after the record date mentioned above.

               (v)   In case of any reclassification of the Common Stock or any
         compulsory share exchange pursuant to which the Common Stock is
         converted into other securities, cash or property, the Holders shall
         have the right thereafter to, at their option, (A) convert the then
         outstanding principal amount, together with all accrued but unpaid
         interest and any other amounts then owing hereunder in respect of this
         Debenture only, into the shares of stock and other securities, cash and
         property receivable upon or deemed to be held by holders of the Common
         Stock following such reclassification or share exchange, and the
         Holders of the Debentures shall be entitled upon such event to receive
         such amount of securities, cash or property as the shares of the Common
         Stock of the Company into which the then outstanding principal amount,
         together with all

                                       13

<PAGE>   44

         accrued but unpaid interest and any other amounts then owing hereunder
         in respect of this Debenture could have been converted immediately
         prior to such reclassification or share exchange would have been
         entitled or (B) require the Company to prepay the aggregate of its
         outstanding principal amount of Debentures, plus all interest and other
         amounts due and payable thereon, at a price determined in accordance
         with Section 3(b). The entire prepayment price shall be paid in cash.
         This provision shall similarly apply to successive reclassifications or
         share exchanges.

               (vi)   All calculations under this Section 4 shall be made to the
         nearest cent or the nearest 1/100th of a share, as the case may be. No
         adjustments in the Conversion Price shall be required if such
         adjustment is less than $0.01, provided, however, that any adjustments
         which by reason of this Section are not required to be made shall be
         carried forward and taken into account in any subsequent adjustment.

               (vii)  Whenever the Conversion Price is adjusted pursuant hereto,
         the Company shall promptly mail to each Holder a notice setting forth
         the Conversion Price after such adjustment and setting forth a brief
         statement of the facts requiring such adjustment.

               (viii) If (A) the Company shall declare a dividend (or any other
         distribution) on the Common Stock; (B) the Company shall declare a
         special nonrecurring cash dividend on or a redemption of the Common
         Stock; (C) the Company shall authorize the granting to all holders of
         the Common Stock rights or warrants to subscribe for or purchase any
         shares of capital stock of any class or of any rights; (D) the approval
         of any stockholders of the Company shall be required in connection with
         any reclassification of the Common Stock, any consolidation or merger
         to which the Company is a party, any sale or transfer of all or
         substantially all of the assets of the Company, of any compulsory share
         exchange whereby the Common Stock is converted into other securities,
         cash or property; (E) the Company shall authorize the voluntary or
         involuntary dissolution, liquidation or winding up of the affairs of
         the Company; then, in each case, the Company shall cause to be filed at
         each office or agency maintained for the purpose of conversion of the
         Debentures, and shall cause to be mailed to the Holders at their last
         addresses as they shall appear upon the stock books of the Company, at
         least twenty calendar days prior to the applicable record or effective
         date hereinafter specified, a notice stating (x) the date on which a
         record is to be taken for the purpose of such dividend, distribution,
         redemption, rights or warrants, or if a record is not to be taken, the
         date as of which the holders of the Common Stock of record to be
         entitled to such dividend, distributions, redemption, rights or
         warrants are to be determined or (y) the date on which such
         reclassification, consolidation, merger, sale, transfer or share
         exchange is expected to become effective or close, and the date as of
         which it is expected that holders of the Common Stock of record shall
         be entitled to exchange their shares of the Common Stock for
         securities, cash or other property deliverable upon such
         reclassification, consolidation, merger, sale, transfer or share
         exchange, provided, that the failure to mail such notice or any defect
         therein or in the mailing thereof shall not affect the validity of the
         corporate action required to be

                                       14

<PAGE>   45

         specified in such notice. Holders are entitled to convert Debentures
         during the twenty-day period commencing the date of such notice to the
         effective date of the event triggering such notice.

               (ix)  Except as contemplated by the Merger Agreement, in case of
         any (1) merger or consolidation of the Company with or into another
         Person, or (2) sale by the Company of more than one-half of the assets
         of the Company (based upon then fair market value) in one or a series
         of related transactions, a Holder shall have the right to (A) if
         permitted under Section 3(b) hereof, exercise its rights of prepayment
         under Section 3(b) with respect to such event, or (B) convert its
         aggregate principal amount of Debentures then outstanding into the
         shares of stock and other securities, cash and property receivable upon
         or deemed to be held by holders of Common Stock following such merger,
         consolidation or sale, and such Holder shall be entitled upon such
         event or series of related events to receive such amount of securities,
         cash and property as the shares of Common Stock into which such
         aggregate principal amount of Debentures could have been converted
         immediately prior to such merger, consolidation or sales would have
         been entitled, or (C) in the event that the Holder shall have elected
         under clause (A) above and the Company shall not have failed to pay the
         amounts due under Section 3(b) by the second Business Day prior to the
         closing of such Change of Control Transaction, or shall have indicated
         its intention to do so, then in the case of a merger or consolidation
         at the closing thereof, (x) require the surviving entity to issue
         shares of convertible preferred stock or convertible debentures with
         such aggregate stated value or in such face amount, as the case may be,
         equal to the aggregate principal amount of Debentures then held by such
         Holder, plus all accrued and unpaid interest and other amounts owing
         thereon, which newly issued shares of preferred stock or debentures
         shall have terms identical (including with respect to conversion) to
         the terms of this Debenture (except, in the case of preferred stock, as
         may be required to reflect the differences between equity and debt) and
         shall be entitled to all of the rights and privileges of a Holder of
         Debentures set forth herein and the agreements pursuant to which the
         Debentures were issued (including, without limitation, as such rights
         relate to the acquisition, transferability, registration and listing of
         such shares of stock other securities issuable upon conversion
         thereof), and (y) simultaneously with the issuance of such convertible
         preferred stock or convertible debentures, shall have the right to
         convert such instrument only into shares of stock and other securities,
         cash and property receivable upon or deemed to be held by holders of
         Common Stock following such merger or consolidation. In the case of
         clause (C), the conversion price applicable for the newly issued shares
         of convertible preferred stock or convertible debentures shall be based
         upon the amount of securities, cash and property that each share of
         Common Stock would receive in such transaction and the Conversion Price
         in effect immediately prior to the effectiveness or closing date for
         such transaction. The terms of any such merger, sale or consolidation
         shall include such terms so as to continue to give the Holders the
         right to receive the securities, cash and property set forth in this
         Section upon any conversion or redemption following such event. This
         provision shall similarly apply to successive such events.

                                       15
<PAGE>   46

               (x)   In the event that at any time prior to the Third Closing
         Date (as defined in the Purchase Agreement) the Exchange Ratio (as
         defined in the Merger Agreement) is modified such that each share of
         Cereus Common Stock (as defined in the Merger Agreement) issued and
         outstanding immediately prior to the Effective Time (as defined in the
         Merger Agreement) shall be converted into the right to receive, without
         interest, more than 1.75 fully paid and non-assessable shares of Parent
         Common Stock (as defined in the Merger Agreement), then the Conversion
         Price shall be decreased proportionately as follows:

                CP=         PX
                            --
                      X+((CN)-- (CO))

Where:
                CP=   New Conversion Price;

                P=    $4.80;

                X=    41,6506,823;

                C=    9,023,444;

                O=    1.75; and

                N=    The new Exchange Ratio.

         (g)   The Company covenants that it will at all times reserve and keep
available out of its authorized and unissued shares of Common Stock solely for
the purpose of issuance upon conversion of the Debentures and payment of
interest on the Debentures, each as herein provided, free from preemptive rights
or any other actual contingent purchase rights of persons other than the
Holders, not less than such number of shares of the Common Stock as shall
(subject to any additional requirements of the Company as to reservation of such
shares set forth in the Purchase Agreement) be issuable (taking into account the
adjustments and restrictions of Section 4(b)) upon the conversion of the
outstanding principal amount of the Debentures and payment of interest
hereunder. The Company covenants that all shares of Common Stock that shall be
so issuable shall, upon issue, be duly and validly authorized, issued and fully
paid, nonassessable and, if the Underlying Shares Registration Statement has
been declared effective under the Securities Act, registered for public sale in
accordance with such Underlying Shares Registration Statement.

         (h)   Upon a conversion hereunder the Company shall not be required to
issue stock certificates representing fractions of shares of the Common Stock,
but may if otherwise permitted, make a cash payment in respect of any final

splits, stock dividends and the like) for fifteen consecutive Trading Days then,
and in such event the Holder shall at any time thereafter have the option to
require the Company to prepay this Debenture for an amount equal to the
Mandatory Prepayment Amount plus any and all accrued and unpaid interest (the
"Put Prepayment Amount") by notifying the Company in writing of its election to
do so (a "Put Notice"). Within five Business Days of receipt of a Put Notice,
the Company shall either pay the Put Prepayment Amount or advise the Holder in
writing (an "Election Notice") that it has elected not to prepay this Debenture,
but instead has elected to reduce the Conversion Price, in which event the
Company shall not be required to prepay this Debenture and the Conversion Price
then in effect shall thereafter be adjusted on the first day of each month
following the giving of the Put Notice to an amount which shall equal the lesser
(a) of the Conversion Price in effect on the first day of such month or (b) the
average Per Share Market Value for the last ten Trading Days of the prior month
(i.e., if the Conversion Price in effect on September 1, 2000 were $5.50 per
share and the average Per Share Market Value for the last ten Trading Days of
August 2000 were $3.25 per share, the Conversion Price would on and after
September 1, 2000 be $3.25 per share and, if the Conversion Price thereafter
remained unchanged until October 1, 2000 and the average Per Share Market Value
for the last ten Trading Days of September 2000 were $3.50 per share the
Conversion Price in effect from and after October 1, 2000 would remain $3.25 per
share, etc.)

         (b)   In the event the Company fails to deliver an Election Notice
within the prescribed period, then, and in such event, the Holder shall have
twenty business days to advise the Company in writing of its election to receive
the Put Prepayment Amount which, in such event, shall be immediately due and
payable, or to reduce the Conversion Price as provided in this Section,
retroactive to the date of the Put Notice.

         (c)   If at any time after the Original Issue Date the following two
conditions are met, the options set forth in Section 5(a) and 5(b) above, if not
previously effected, shall terminate and be of no further force and effect (if
the option set forth in Section 5(b) above shall have previously been exercised,
no further adjustment shall thereafter be required):

               (i)   The Per Share Market Value shall exceed $6.00 (as adjusted
for stock dividends or any subdivision, combination or reclassification of the
Common Stock) for a period of Twenty Consecutive Trading Days (the "Measurement
Period"); and

               (ii)  The Underlying Share Registration Statement shall have been
effective at all times during the Measurement Period.

         (d)   If the Cereus Merger shall not have been consummated on or prior
to the 150th day after the Original Issuance Date, then by notifying the Company
in writing of its election to do so (a "Redemption Notice"), the Holder shall
have, at any time thereafter, the option to require the Company to prepay this
Debenture for the "Prepayment Amount" (as defined below). The Prepayment Amount
shall equal, (i) if such prepayment is made on or before the ninetieth day
following the Redemption Notice, one-hundred percent of the principal amount of
this Debenture, (ii) if such prepayment is made after the ninetieth day but on
or before the one hundred eightieth day following the Redemption Notice, one
hundred ten percent of the principal amount of this Debenture, and (iii) if such
prepayment is made after the one hundred eightieth day following the Redemption
Notice, one hundred twenty percent of the principal amount of this Debenture, in
each case together with any and all accrued and unpaid interest through the date
of payment. Until this Debenture is paid in full, Holder shall have all of its
rights hereunder without interruption or modification notwithstanding its
delivery of Redemption Notice.

    Section 6. Unconditional Obligation. Except as expressly provided herein, no
provision of this Debenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of, interest and
liquidated damages (if any) on, this Debenture at the time, place, and rate, and
in the coin or currency, herein prescribed. This Debenture is a direct
obligation of the Company. This Debenture ranks pari passu with all other

there are Debentures outstanding, the Company shall not and shall cause it
subsidiaries not to, without the consent of the Holders, (i) amend its
certificate of incorporation, bylaws or other charter documents so as to
adversely affect any rights of the Holders (creation of a class of preferred

conversion of all or a portion of the Subordinated Indebtedness to Common Stock)

or PNC Event of Default exists or would exist. In no event shall any Lender's
continuing to honor any requests of Company or any other borrower for loans or
other extensions of credit under the PNC Agreement after the occurrence or

         (g)    Holder agrees and acknowledges that in no event shall Holder
accept, receive or otherwise obtain any Lien on any assets of Company or any of
its subsidiaries. If, notwithstanding the foregoing, Holder is granted or

be subordinated to any and all Liens held by any Senior Creditor on any such
assets.

         (h)    If the Senior Indebtedness has been indefeasibly paid and
discharged, Holder 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 Indebtedness, to the extent of all
payments and distributions paid over to or for the benefit of Senior Creditors
pursuant to this Section 11 on account of the Subordinated Indebtedness. In no

Creditor for any alleged impairment of Holder's subrogation rights, Holder
acknowledging that any actions taken by a Senior Creditor with respect to the
Senior Indebtedness or the collateral securing all or any part of the Senior
Indebtedness are authorized and consented to by Holder.

         (i)    The provisions of this Debenture subordinating the Subordinated
Indebtedness are solely for the purpose of defining the relative rights of
Senior Creditors and Holder and shall not impair, as between Holder and Company,

                                       23

                                     WARRANT

Warrant No. _______

Dated:       July 27, 2000

    Eltrax Systems, Inc., a Minnesota corporation (the "Company"), hereby
certifies that, for value received, [                      ] or its registered
assigns ("Holder"), is entitled, subject to the terms set forth below, to
purchase from the Company up to a total of 364,5841 shares of common stock, $.01
par value per share (the "Common Stock"), of the Company (each such share, a
"Warrant Share" and all such shares, the "Warrant Shares"). The initial
"Exercise Price" for Warrant Shares shall be $5.03 and shall be subject to
adjustment from time to time as provided in Section 7. The Holder may acquire
Warrant Shares under this Warrant at any time and from time to time from and
after the date hereof and through and including July 26, 2005 (the "Expiration
Date").

    This Warrant shall be subject to the following terms and conditions:

    1. Registration of Warrant. The Company shall register this Warrant, upon
records to be maintained by the Company for that purpose (the "Warrant
Register"), in the name of the record Holder hereof from time to time. The
Company may deem and treat the registered Holder of this Warrant as the absolute
owner hereof for the purpose of any exercise hereof or any distribution to the
Holder, and for all other purposes, and the Company shall not be affected by
notice to the contrary.

    2.   Registration of Transfers and Exchanges.

         (a) The Company shall register the transfer of any portion of this
Warrant in the Warrant Register, upon surrender of this Warrant, with the Form
of Assignment attached hereto duly completed and signed, to the Transfer Agent
or to the Company at its address for notice set forth in Section 11. Upon any
such registration or transfer, a new warrant to purchase Common Stock, in
substantially the form of this Warrant (any such new warrant, a "New Warrant"),
evidencing the portion of this Warrant so transferred shall be issued to the
transferee and a New Warrant evidencing the remaining portion of this Warrant
not so transferred, if any, shall be issued to the transferring Holder. The
acceptance of the New Warrant by the transferee thereof shall be deemed the
acceptance of such transferee of all of the rights and obligations of a holder
of a Warrant.

         (b) This Warrant is exchangeable, upon the surrender hereof by the
Holder to the office of the Company at its address for notice set forth in
Section 11 for one or more New Warrants, evidencing in the aggregate the right
to purchase the number of Warrant Shares which may then be purchased hereunder.
Any such New Warrant will be dated the date of such exchange.

         (c) This Warrant has been issued subject to certain investment
representations of the original Holder set forth in the Convertible Debenture
Purchase Agreement among the Company and the Holder dated as of July 27, 2000
(the "Purchase Agreement") and may only be transferred or exchanged in
compliance with the transfer restrictions contained therein.

    3.   Duration and Exercise of Warrants.

         (a) This Warrant shall be exercisable by the registered Holder on any
business day before 6:30 P.M., New York City time, at any time and from time to
time on or after the date hereof to and including the Expiration Date. At 6:30
P.M., New York City time on the Expiration Date, the portion of this Warrant not
exercised prior thereto shall be and become void and of no value. Prior to the
Expiration Date, the Company may not call or otherwise redeem this Warrant
without the prior written consent of the Holder.

         (b) Upon surrender of this Warrant, with the Form of Election to
Purchase attached hereto duly completed and signed, to the Company at its
address for notice set forth in Section 12 and upon payment of the Exercise
Price multiplied by the number of Warrant Shares that the Holder intends to
purchase hereunder, in the manner provided hereunder, all as specified by the
Holder in the Form of Election to Purchase, the Company shall promptly (but in
no event later than three business days after the Date of Exercise (as defined
herein)) issue or cause to be issued and cause to be delivered to or upon the
written order of the Holder and in such name or names as the Holder may
designate, a certificate for the Warrant Shares issuable upon such exercise,
free of restrictive legends except (i) either in the event that a registration
statement covering the resale of the Warrant Shares and naming the Holder as a
selling stockholder thereunder is not then effective or the Warrant Shares are
not freely

                                       2
<PAGE>   64

transferable without volume restrictions pursuant to Rule 144(k) promulgated
under the Securities Act of 1933, as amended (the "Securities Act"), or (ii) if
this Warrant shall have been issued pursuant to a written agreement between the
original Holder and the Company, as required by such agreement. Any person so
designated by the Holder to receive Warrant Shares shall be deemed to have
become holder of record of such Warrant Shares as of the Date of Exercise of
this Warrant. The Company shall, upon request of the Holder, if available, use
its best efforts to deliver Warrant Shares hereunder electronically through the
Depository Trust Corporation or another established clearing corporation
performing similar functions.

         (c) A "Date of Exercise" means the date on which the Company shall have
received (i) this Warrant (or any New Warrant, as applicable), with the Form of
Election to Purchase attached hereto (or attached to such New Warrant)
appropriately completed and duly signed, and (ii) payment of the Exercise Price
for the number of Warrant Shares so indicated by the Holder hereof to be
purchased.

         (d) This Warrant shall be exercisable, either in its entirety or, from
time to time, for a portion of the number of Warrant Shares, representing not
less than 10% of the original Warrant Shares or such lesser amount as is then
remaining available for exercise. If less than all of the Warrant Shares which
may be purchased under this Warrant are exercised at any time, the Company shall
issue or cause to be issued, at its expense, a New Warrant evidencing the right
to purchase the remaining number of Warrant Shares for which no exercise has
been evidenced by this Warrant.

    4.   Payment of Taxes. The Company will pay all documentary stamp taxes
attributable to the issuance of Warrant Shares upon the exercise of this
Warrant; provided, however, that the Company shall not be required to pay any
tax which may be payable in respect of any transfer involved in the registration
of any certificates for Warrant Shares or Warrants in a name other than that of
the Holder. The Holder shall be responsible for all other tax liability that may
arise as a result of holding or transferring this Warrant or receiving Warrant
Shares upon exercise hereof.

    5.   Replacement of Warrant. If this Warrant is mutilated, lost, stolen or
destroyed, the Company shall issue or cause to be issued in exchange and
substitution for and upon cancellation hereof, or in lieu of and substitution
for this Warrant, a New Warrant, but only upon receipt of evidence reasonably
satisfactory to the Company of such loss, theft or destruction and indemnity, if
requested, satisfactory to it. Applicants for a New Warrant under such
circumstances shall also comply with such other reasonable regulations and
procedures and pay such other reasonable charges as the Company may prescribe.

    6.   Reservation of Warrant Shares. The Company covenants that it will at
all times reserve and keep available out of the aggregate of its authorized but
unissued Common Stock, solely for the purpose of enabling it to issue Warrant
Shares upon exercise of this Warrant as herein provided, the number of Warrant
Shares which are then issuable and deliverable upon the exercise of this entire
Warrant, free from preemptive rights or any other actual contingent purchase
rights of persons other than the Holder (taking into account the adjustments and

                                       3

<PAGE>   65

restrictions of Section 7). The Company covenants that all Warrant Shares that
shall be so issuable and deliverable shall, upon issuance and the payment of the
applicable Exercise Price in accordance with the terms hereof, be duly and
validly authorized, issued and fully paid and nonassessable.

    7. Certain Adjustments. The Exercise Price and number of Warrant Shares
issuable upon exercise of this Warrant are subject to adjustment from time to
time as set forth in this Section 7. Upon each such adjustment of the Exercise
Price pursuant to this Section 7, the Holder shall thereafter prior to the
Expiration Date be entitled to purchase, at the Exercise Price resulting from
such adjustment, the number of Warrant Shares obtained by multiplying the
Exercise Price in effect immediately prior to such adjustment by the number of
Warrant Shares issuable upon exercise of this Warrant immediately prior to such
adjustment and dividing the product thereof by the Exercise Price resulting from
such adjustment.

         (a) If the Company, at any time while this Warrant is outstanding, (i)
shall pay a stock dividend (except scheduled dividends paid on preferred stock
which contain a stated dividend rate) or otherwise make a distribution or
distributions on shares of its Common Stock or on any other class of capital
stock payable in shares of Common Stock, (ii) subdivide outstanding shares of
Common Stock into a larger number of shares, or (iii) combine outstanding shares
of Common Stock into a smaller number of shares, the Exercise Price shall be
multiplied by a fraction of which the numerator shall be the number of shares of
Common Stock (excluding treasury shares, if any) outstanding before such event
and of which the denominator shall be the number of shares of Common Stock
(excluding treasury shares, if any) outstanding after such event. Any adjustment
made pursuant to this Section shall become effective immediately after the
record date for the determination of stockholders entitled to receive such
dividend or distribution and shall become effective immediately after the
effective date in the case of a subdivision or combination, and shall apply to
successive subdivisions and combinations.

         (b) In case of any reclassification of the Common Stock or any
compulsory share exchange pursuant to which the Common Stock is converted into
other securities, cash or property, then the Holder shall have the right
thereafter to exercise this Warrant only into the shares of stock and other
securities and property receivable upon or deemed to be held by holders of
Common Stock following such reclassification or share exchange, and the Holder
shall be entitled upon such event to receive such amount of securities or
property equal to the amount of Warrant Shares such Holder would have been
entitled to had such Holder exercised this Warrant immediately prior to such
reclassification or share exchange. The terms of any such reclassification or
share exchange shall include such terms so as to continue to give to the Holder
the right to receive the securities or property set forth in this Section 7(b)
upon any exercise following any such reclassification or share exchange.

         (c) If the Company, at any time while this Warrant is outstanding,
shall distribute to all holders of Common Stock (and not to holders of this
Warrant) evidences of its indebtedness or assets or rights or warrants to
subscribe for or purchase any security (excluding those referred to in Sections
7(a), (b) and (d)), then in each such case the Exercise

                                       4

<PAGE>   66

Price shall be determined by multiplying the Exercise Price in effect
immediately prior to the record date fixed for determination of stockholders
entitled to receive such distribution by a fraction of which the denominator
shall be the Exercise Price determined as of the record date mentioned above,
and of which the numerator shall be such Exercise Price on such record date less
the then fair market value at such record date of the portion of such assets or
evidence of indebtedness so distributed applicable to one outstanding share of
Common Stock as determined by the Company's independent certified public
accountants that regularly examines the financial statements of the Company (an
"Appraiser").

         (d) If the Company or any subsidiary thereof, as applicable with
respect to Common Stock Equivalents (as defined below), at any time while this
Warrant is outstanding, shall issue shares of Common Stock or rights, warrants,
options or other securities or debt that is convertible into or exchangeable for
shares of Common Stock ("Common Stock Equivalents"), entitling any person to
acquire shares of Common Stock at a price per share less than the Exercise Price
(if the holder of the Common Stock or Common Stock Equivalent so issued shall at
any time, whether by operation of purchase price adjustments, reset provisions,
floating conversion, exercise or exchange prices or otherwise, or due to
warrants, options or rights issued in connection with such issuance, be entitled
to receive shares of Common Stock at a price less than the Exercise Price, such
issuance shall be deemed to have occurred for less than the Exercise Price),
then the Exercise Price shall be multiplied by a fraction, the numerator of
which shall be the number of shares of Common Stock outstanding immediately
prior to the issuance of such Common Stock or such Common Stock Equivalents plus
the number of shares of Common Stock which the offering price for such shares of
Common Stock or Common Stock Equivalents would purchase at the Exercise Price,
and the denominator of which shall be the sum of the number of shares of Common
Stock outstanding immediately prior to such issuance plus the number of shares
of Common Stock so issued or issuable, provided, that for purposes hereof, all
shares of Common Stock that are issuable upon conversion, exercise or exchange
of Common Stock Equivalents shall be deemed outstanding immediately after the
issuance of such Common Stock Equivalents. Such adjustment shall be made
whenever such Common Stock or Common Stock Equivalents are issued. However, upon
the expiration of any Common Stock Equivalents the issuance of which resulted in
an adjustment in the Exercise Price pursuant to this Section, if any such Common
Stock Equivalents shall expire and shall not have been exercised, the Exercise
Price shall immediately upon such expiration be recomputed and effective
immediately upon such expiration be increased to the price which it would have
been (but reflecting any other adjustments in the Exercise Price made pursuant
to the provisions of this Section after the issuance of such Common Stock
Equivalents) had the adjustment of the Exercise Price made upon the issuance of
such Common Stock Equivalents been made on the basis of offering for
subscription or purchase only that number of shares of the Common Stock actually
purchased upon the exercise of such Common Stock Equivalents actually exercised.
The foregoing shall not apply to any (i) issuances of securities as
consideration in a merger, consolidation or acquisition of assets, or in
connection with any strategic partnership or joint venture (the primary purpose
of which is not to raise equity capital), or as consideration for the
acquisition of a business, product or license by the Company, (ii) the issuance
of securities upon the exercise or conversion of the Company's options, warrants
or other convertible securities

                                       5

<PAGE>   67

outstanding as of the date hereof, or (iii) the grant of options or warrants, or
the issuance of additional securities, under any duly authorized Company stock
option, restricted stock plan or stock purchase plan for the benefit of the
Company's employees.

         (e) Except as contemplated by the Merger Agreement (as defined in the
Purchase Agreement) in case of any (1) merger or consolidation of the Company
with or into another Person, or (2) sale by the Company of more than one-half of
the assets of the Company (based upon then fair market value) in one or a series
of related transactions, (A) the Holder shall have the right at all times from
and after the date of such merger, sale or consolidation, as the case may be, to
and including the Expiration Date, to exercise this Warrant for the shares of
stock and other securities, cash and property receivable upon or deemed to be
held by holders of Common Stock immediately following such merger, consolidation
or sale, and the Holder shall be entitled upon such event or series of related
events to receive such amount of securities, cash and property as the Common
Stock for which this Warrant could have been exercised immediately prior to such
merger, consolidation or sales would have been entitled, or (B) the acquiring
company or newly created company shall have the right to pay the Holder the
value of the Warrant determined on a Black-Scholes basis. (For example, if (1)
the Company merges with and into another Person ("Newco") and as a result
thereof each share of Common Stock shall entitle the holder thereof to receive
two shares of the common stock of Newco and $2.00 in cash, and (2) the Exercise
Price is at the effective time of such merger $6.00 per share, then at all times
thereafter this Warrant shall upon the payment of $6.00 times the number of
Warrant Shares represent the right to receive (A) that number of shares of the
Common Stock of Newco as is equal to two times the Warrant Shares, and (B) that
amount of cash as is equal to $2.00 times the number of Warrant Shares.) The
terms of any such merger, sale or consolidation shall include such terms so as
to continue to give the Holder the right to receive the securities, cash and
property set forth in this Section upon any conversion or redemption following
such event. This provision shall similarly apply to successive such events.

         (f)  For the purposes of this Section 7, the following clauses shall
also be applicable:

              (i) Record Date. In case the Company shall take a record of the
holders of its Common Stock for the purpose of entitling them (A) to receive a
dividend or other distribution payable in Common Stock or in securities
convertible or exchangeable into shares of Common Stock, or (B) to subscribe for
or purchase Common Stock or securities convertible or exchangeable into shares
of Common Stock, then such record date shall be deemed to be the date of the
issue or sale of the shares of Common Stock deemed to have been issued or sold
upon the declaration of such dividend or the making of such other distribution
or the date of the granting of such right of subscription or purchase, as the
case may be.

              (ii) Treasury Shares. The number of shares of Common Stock
outstanding at any given time shall not include shares owned or held by or for
the account of the Company, and the disposition of any such shares shall be
considered an issue or sale of Common Stock.

                                       6

<PAGE>   68

         (g) All calculations under this Section 7 shall be made to the nearest
cent or the nearest 1/100th of a share, as the case may be.

         (h) Whenever the Exercise Price is adjusted pursuant to Section 7(c)
above, the Holder, after receipt of the determination by the Appraiser, shall
have the right to select an additional appraiser (which shall be a nationally
recognized accounting firm), in which case the adjustment shall be equal to the
average of the adjustments recommended by each of the Appraiser and such
appraiser. The Holder shall promptly mail or cause to be mailed to the Company,
a notice setting forth the Exercise Price after such adjustment and setting
forth a brief statement of the facts requiring such adjustment. Such adjustment
shall become effective immediately after the record date mentioned above.

         (i) If:

                  (i)      the Company shall declare a dividend (or any other
                           distribution) on its Common Stock; or

                  (ii)     the Company shall declare a special nonrecurring cash
                           dividend on or a redemption of its Common Stock; or

                  (iii)    the Company shall authorize the granting to all
                           holders of the Common Stock rights or warrants to
                           subscribe for or purchase any shares of capital stock
                           of any class or of any rights; or

                  (iv)     the approval of any stockholders of the Company shall
                           be required in connection with any reclassification
                           of the Common Stock, any consolidation or merger to
                           which the Company is a party, any sale or transfer of
                           all or substantially all of the assets of the
                           Company, or any compulsory share exchange whereby the
                           Common Stock is converted into other securities, cash

                  (v)      the Company shall authorize the voluntary
                           dissolution, liquidation or winding up of the affairs
                           of the Company,

then the Company shall cause to be mailed to each Holder at their last addresses
as they shall appear upon the Warrant Register, at least twenty calendar days
prior to the applicable record or effective date hereinafter specified, a notice
stating (x) the date on which a record is to be taken for the purpose of such
dividend, distribution, redemption, rights or warrants, or if a record is not to
be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distributions, redemption, rights or warrants are to
be determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or share exchange is expected to become effective or
close, and the date as of which it is expected that

                                       7

<PAGE>   69

holders of Common Stock of record shall be entitled to exchange their shares of
Common Stock for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, share exchange,
dissolution, liquidation or winding up; provided, however, that the failure to
mail such notice or any defect therein or in the mailing thereof shall not
affect the validity of the corporate action required to be specified in such
notice.

    8.   Payment of Exercise Price. The Holder shall pay the Exercise Price in
one of the following manners:

         (a) Cash Exercise. The Holder may deliver immediately available funds;
or

         (b) Cashless Exercise. In the event, but only in such event, that on or
after the Effective Date (as defined in the Purchase Agreement) a Registration
Statement covering the resale of the Warrant Shares has not been declared
effective, then the Holder may surrender this Warrant to the Company together
with a notice of cashless exercise, in which event the Company shall issue to
the Holder the number of Warrant Shares determined as follows:

                                            X = Y [(A-B)/A]

         where:

                                            X = the number of Warrant Shares to
                                            be issued to the Holder.

                                            Y = the number of Warrant Shares
                                            with respect to which this Warrant
                                            is being exercised.

                                            A = the average of the closing sale
                                            prices of the Common Stock for the
                                            five (5) trading days immediately
                                            prior to (but not including) the
                                            Date of Exercise.

                                            B = the Exercise Price.

For purposes of Rule 144 promulgated under the Securities Act, it is intended,
understood and acknowledged that the Warrant Shares issued in a cashless
exercise transaction shall be deemed to have been acquired by the Holder, and
the holding period for the Warrant Shares shall be deemed to have been
commenced, on the issue date.

     9.  Certain Exercise Restrictions.

         (a) A Holder may not exercise this Warrant to the extent such exercise
would result in the Holder, together with any affiliate thereof, beneficially
owning (as determined in accordance with Section 13(d) of the Securities
Exchange Act of 1934, as

                                       8

<PAGE>   70

amended (the "Exchange Act") and the rules promulgated thereunder) in excess of
4.999% of the then issued and outstanding shares of Common Stock, including
shares issuable upon such exercise and held by such Holder after application of
this Section. Since the Holder will not be obligated to report to the Company
the number of shares of Common Stock it may hold at the time of an exercise
hereunder, unless the exercise at issue would result in the issuance of shares
of Common Stock in excess of 4.999% of the then outstanding shares of Common
Stock without regard to any other shares which may be beneficially owned by the
Holder or an affiliate thereof, the Holder shall have the authority and
obligation to determine whether the restriction contained in this Section will
limit any particular exercise hereunder and to the extent that the Holder
determines that the limitation contained in this Section applies, the
determination of which portion of this Warrant is exercisable shall be the
responsibility and obligation of the Holder. If the Holder has delivered a Form
of Election to Purchase for a number of Warrant Shares that, without regard to
any other shares that the Holder or its affiliates may beneficially own, would
result in the issuance in excess of the permitted amount hereunder, the Company
shall notify the Holder of this fact and shall honor the exercise for the
maximum portion of this Warrant permitted to be exercised on such Date of
Exercise in accordance with the periods described herein and, at the option of
the Holder, either keep the portion of the Warrant tendered for exercise in
excess of the permitted amount hereunder for future exercises or return such
excess portion of the Warrant to the Holder. The provisions of this Section may
be waived by a Holder (but only as to itself and not to any other Holder) upon
not less than sixty-one days prior notice to the Company. Other Holders shall be
unaffected by any such waiver.

                  (b) A Holder may not exercise this Warrant to the extent such
exercise would result in the Holder, together with any affiliate thereof,
beneficially owning (as determined in accordance with Section 13(d) of the
Exchange Act and the rules promulgated thereunder) in excess of 9.999% of the
then issued and outstanding shares of Common Stock, including shares issuable
upon such exercise and held by such Holder after application of this Section.
Since the Holder will not be obligated to report to the Company the number of
shares of Common Stock it may hold at the time of an exercise hereunder, unless
the exercise at issue would result in the issuance of shares of Common Stock in
excess of 9.999% of the then outstanding shares of Common Stock without regard
to any other shares which may be beneficially owned by the Holder or an
affiliate thereof, the Holder shall have the authority and obligation to
determine whether the restriction contained in this Section will limit any
particular exercise hereunder and to the extent that the Holder determines that
the limitation contained in this Section applies, the determination of which
portion of this Warrant is exercisable shall be the responsibility and
obligation of the Holder. If the Holder has delivered a Form of Election to
Purchase for a number of Warrant Shares that, without regard to any other shares
that the Holder or its affiliates may beneficially own, would result in the
issuance in excess of the permitted amount hereunder, the Company shall notify
the Holder of this fact and shall honor the exercise for the maximum portion of
this Warrant permitted to be exercised on such Date of Exercise in accordance
with the periods described herein and, at the option of the Holder, either keep
the portion of the Warrant tendered for exercise in excess of the permitted
amount hereunder for future exercises or return such excess portion of the
Warrant to the Holder. The provisions of this Section may be waived by a Holder
(but only as to itself

                                       9

<PAGE>   71

and not to any other Holder) upon not less than sixty-one days prior notice to
the Company. Other Holders shall be unaffected by any such waiver.

    10. Fractional Shares. The Company shall not be required to issue or cause
to be issued fractional Warrant Shares on the exercise of this Warrant. The
number of full Warrant Shares which shall be issuable upon the exercise of this
Warrant shall be computed on the basis of the aggregate number of Warrant Shares
purchasable on exercise of this Warrant so presented. If any fraction of a
Warrant Share would, except for the provisions of this Section, be issuable on
the exercise of this Warrant, the Company shall pay an amount in cash equal to
the Exercise Price multiplied by such fraction.

    11. Notices. Any and all notices or other communications or deliveries
hereunder shall be in writing and shall be deemed given and effective on the
earliest of (i) the date of transmission, if such notice or communication is
delivered via facsimile at the facsimile telephone number specified in this
Section prior to 6:30 p.m. (New York City time) on a business day, (ii) the
business day after the date of transmission, if such notice or communication is

Section later than 6:30 p.m. (New York City time) on any date and earlier than
11:59 p.m. (New York City time) on such date, (iii) the business day following

                              ELTRAX SYSTEMS, INC.

                                     WARRANT

Warrant No. _______

Dated:   July 27, 2000

    Eltrax Systems, Inc., a Minnesota corporation (the "Company"), hereby
certifies that, for value received, [ ] or its registered assigns ("Holder"), is
entitled, subject to the terms set forth below, to purchase from the Company up
to a total of 52,0831 shares of common stock, $.01 par value per share (the
"Common Stock"), of the Company (each such share, a "Warrant Share" and all such
shares, the "Warrant Shares"). The initial "Exercise Price" for Warrant Shares
shall be $5.03, and shall be subject to adjustment from time to time as provided
in Section 7. The Holder may acquire Warrant Shares under this Warrant at such
times as is provided for in Section 3(a) hereof.

    This Warrant shall be subject to the following terms and conditions:

    1.   Registration of Warrant. The Company shall register this Warrant, upon
records to be maintained by the Company for that purpose (the "Warrant
Register"), in the name of the record Holder hereof from time to time. The
Company may deem and treat the registered Holder of this Warrant as the absolute
owner hereof for the purpose of any exercise hereof or any distribution to the
Holder, and for all other purposes, and the Company shall not be affected by
notice to the contrary.

    2.   Registration of Transfers and Exchanges.

         (a) The Company shall register the transfer of any portion of this
Warrant in the Warrant Register, upon surrender of this Warrant, with the Form
of Assignment attached

<PAGE>   79
hereto duly completed and signed, to the Transfer Agent or to the Company at its
address for notice set forth in Section 11. Upon any such registration or
transfer, a new warrant to purchase Common Stock, in substantially the form of
this Warrant (any such new warrant, a "New Warrant"), evidencing the portion of
this Warrant so transferred shall be issued to the transferee and a New Warrant
evidencing the remaining portion of this Warrant not so transferred, if any,
shall be issued to the transferring Holder. The acceptance of the New Warrant by
the transferee thereof shall be deemed the acceptance of such transferee of all
of the rights and obligations of a holder of a Warrant.

         (b) This Warrant is exchangeable, upon the surrender hereof by the
Holder to the office of the Company at its address for notice set forth in
Section 11 for one or more New Warrants, evidencing in the aggregate the right
to purchase the number of Warrant Shares which may then be purchased hereunder.
Any such New Warrant will be dated the date of such exchange.

         (c) This Warrant has been issued subject to certain investment
representations of the original Holder set forth in the Convertible Debenture
Purchase Agreement among the Company and the Holder dated as of July 27, 2000
(the "Purchase Agreement") and may only be transferred or exchanged in
compliance with the transfer restrictions contained therein.

    3.   Duration and Exercise of Warrants.

         (a) This Warrant shall be exercisable by the registered Holder on any
business day before 6:30 P.M., New York City time, and from time to time from
and after the earliest to occur of (a) one hundred fifty days after the Initial
Closing Date (as such term is defined in Section 1.2 of the Purchase Agreement,
or (b) the Second Closing Date (as such term is defined in Section 1.3 of the
Purchase Agreement), and through and including July 26, 2005 (the "Expiration
Date").; provided, however, that this Warrant shall be null and void ab initio,
and of no force and effect in the event the Holder breaches its obligation to
purchase the Second Tranche Debentures as contemplated by the Purchase
Agreement. At 6:30 P.M., New York City time on the Expiration Date, the portion
of this Warrant not exercised prior thereto shall be and become void and of no
value. Prior to the Expiration Date, the Company may not call or otherwise
redeem this Warrant without the prior written consent of the Holder.

         (b) Upon surrender of this Warrant, with the Form of Election to
Purchase attached hereto duly completed and signed, to the Company at its
address for notice set forth in Section 12 and upon payment of the Exercise
Price multiplied by the number of Warrant Shares that the Holder intends to
purchase hereunder, in the manner provided hereunder, all as specified by the
Holder in the Form of Election to Purchase, the Company shall promptly (but in
no event later than three business days after the Date of Exercise (as defined
herein)) issue or cause to be issued and cause to be delivered to or upon the
written order of the Holder and in such name or names as the Holder may
designate, a certificate for the Warrant Shares issuable upon such exercise,
free of restrictive legends except (i) either in the event that a

                                       2

<PAGE>   80
registration statement covering the resale of the Warrant Shares and naming the
Holder as a selling stockholder thereunder is not then effective or the Warrant
Shares are not freely transferable without volume restrictions pursuant to Rule
144(k) promulgated under the Securities Act of 1933, as amended (the "Securities
Act"), or (ii) if this Warrant shall have been issued pursuant to a written
agreement between the original Holder and the Company, as required by such
agreement. Any person so designated by the Holder to receive Warrant Shares
shall be deemed to have become holder of record of such Warrant Shares as of the
Date of Exercise of this Warrant. The Company shall, upon request of the Holder,
if available, use its best efforts to deliver Warrant Shares hereunder
electronically through the Depository Trust Corporation or another established
clearing corporation performing similar functions.

         (c) A "Date of Exercise" means the date on which the Company shall have
received (i) this Warrant (or any New Warrant, as applicable), with the Form of
Election to Purchase attached hereto (or attached to such New Warrant)
appropriately completed and duly signed, and (ii) payment of the Exercise Price
for the number of Warrant Shares so indicated by the Holder hereof to be
purchased.

         (d) This Warrant shall be exercisable, either in its entirety or, from
time to time, for a portion of the number of Warrant Shares, representing not
less than 10% of the original Warrant Shares or such lesser amount as is then
remaining available for exercise. If less than all of the Warrant Shares which
may be purchased under this Warrant are exercised at any time, the Company shall
issue or cause to be issued, at its expense, a New Warrant evidencing the right
to purchase the remaining number of Warrant Shares for which no exercise has
been evidenced by this Warrant.

    4.   Payment of Taxes. The Company will pay all documentary stamp taxes
attributable to the issuance of Warrant Shares upon the exercise of this
Warrant; provided, however, that the Company shall not be required to pay any
tax which may be payable in respect of any transfer involved in the registration
of any certificates for Warrant Shares or Warrants in a name other than that of
the Holder. The Holder shall be responsible for all other tax liability that may
arise as a result of holding or transferring this Warrant or receiving Warrant
Shares upon exercise hereof.

    5.   Replacement of Warrant. If this Warrant is mutilated, lost, stolen or
destroyed, the Company shall issue or cause to be issued in exchange and
substitution for and upon cancellation hereof, or in lieu of and substitution
for this Warrant, a New Warrant, but only upon receipt of evidence reasonably
satisfactory to the Company of such loss, theft or destruction and indemnity, if
requested, satisfactory to it. Applicants for a New Warrant under such
circumstances shall also comply with such other reasonable regulations and
procedures and pay such other reasonable charges as the Company may prescribe.

    6.   Reservation of Warrant Shares. The Company covenants that it will at
all times reserve and keep available out of the aggregate of its authorized but
unissued Common Stock, solely for the purpose of enabling it to issue Warrant
Shares upon exercise of this Warrant as herein provided, the number of Warrant
Shares which are then issuable and deliverable upon

                                       3

<PAGE>   81
the exercise of this entire Warrant, free from preemptive rights or any other
actual contingent purchase rights of persons other than the Holder (taking into
account the adjustments and restrictions of Section 7). The Company covenants
that all Warrant Shares that shall be so issuable and deliverable shall, upon
issuance and the payment of the applicable Exercise Price in accordance with the
terms hereof, be duly and validly authorized, issued and fully paid and
nonassessable.

    7.   Certain Adjustments. The Exercise Price and number of Warrant Shares
issuable upon exercise of this Warrant are subject to adjustment from time to
time as set forth in this Section 7. Upon each such adjustment of the Exercise
Price pursuant to this Section 7, the Holder shall thereafter prior to the
Expiration Date be entitled to purchase, at the Exercise Price resulting from
such adjustment, the number of Warrant Shares obtained by multiplying the
Exercise Price in effect immediately prior to such adjustment by the number of
Warrant Shares issuable upon exercise of this Warrant immediately prior to such
adjustment and dividing the product thereof by the Exercise Price resulting from
such adjustment.

         (a) If the Company, at any time while this Warrant is outstanding, (i)
shall pay a stock dividend (except scheduled dividends paid on preferred stock
which contain a stated dividend rate) or otherwise make a distribution or
distributions on shares of its Common Stock or on any other class of capital
stock payable in shares of Common Stock, (ii) subdivide outstanding shares of
Common Stock into a larger number of shares, or (iii) combine outstanding shares
of Common Stock into a smaller number of shares, the Exercise Price shall be
multiplied by a fraction of which the numerator shall be the number of shares of
Common Stock (excluding treasury shares, if any) outstanding before such event
and of which the denominator shall be the number of shares of Common Stock
(excluding treasury shares, if any) outstanding after such event. Any adjustment
made pursuant to this Section shall become effective immediately after the
record date for the determination of stockholders entitled to receive such
dividend or distribution and shall become effective immediately after the
effective date in the case of a subdivision or combination, and shall apply to
successive subdivisions and combinations.

         (b) In case of any reclassification of the Common Stock or any
compulsory share exchange pursuant to which the Common Stock is converted into
other securities, cash or property, then the Holder shall have the right
thereafter to exercise this Warrant only into the shares of stock and other
securities and property receivable upon or deemed to be held by holders of
Common Stock following such reclassification or share exchange, and the Holder
shall be entitled upon such event to receive such amount of securities or
property equal to the amount of Warrant Shares such Holder would have been
entitled to had such Holder exercised this Warrant immediately prior to such
reclassification or share exchange. The terms of any such reclassification or
share exchange shall include such terms so as to continue to give to the Holder
the right to receive the securities or property set forth in this Section 8(b)
upon any exercise following any such reclassification or share exchange.

         (c) If the Company, at any time while this Warrant is outstanding,
shall distribute to all holders of Common Stock (and not to holders of this
Warrant) evidences of its

                                       4

<PAGE>   82
indebtedness or assets or rights or warrants to subscribe for or purchase any
security (excluding those referred to in Sections 7(a), (b) and (d)), then in
each such case the Exercise Price shall be determined by multiplying the
Exercise Price in effect immediately prior to the record date fixed for
determination of stockholders entitled to receive such distribution by a
fraction of which the denominator shall be the Exercise Price determined as of
the record date mentioned above, and of which the numerator shall be such
Exercise Price on such record date less the then fair market value at such
record date of the portion of such assets or evidence of indebtedness so
distributed applicable to one outstanding share of Common Stock as determined by
the Company's independent certified public accountants that regularly examines
the financial statements of the Company (an "Appraiser").

         (d) If the Company or any subsidiary thereof, as applicable with
respect to Common Stock Equivalents (as defined below), at any time while this
Warrant is outstanding, shall issue shares of Common Stock or rights, warrants,
options or other securities or debt that is convertible into or exchangeable for
shares of Common Stock ("Common Stock Equivalents"), entitling any person to
acquire shares of Common Stock at a price per share less than the Exercise Price
(if the holder of the Common Stock or Common Stock Equivalent so issued shall at
any time, whether by operation of purchase price adjustments, reset provisions,
floating conversion, exercise or exchange prices or otherwise, or due to
warrants, options or rights issued in connection with such issuance, be entitled
to receive shares of Common Stock at a price less than the Exercise Price, such
issuance shall be deemed to have occurred for less than the Exercise Price),
then the Exercise Price shall be multiplied by a fraction, the numerator of
which shall be the number of shares of Common Stock outstanding immediately
prior to the issuance of such Common Stock or such Common Stock Equivalents plus
the number of shares of Common Stock which the offering price for such shares of
Common Stock or Common Stock Equivalents would purchase at the Exercise Price,
and the denominator of which shall be the sum of the number of shares of Common
Stock outstanding immediately prior to such issuance plus the number of shares
of Common Stock so issued or issuable, provided, that for purposes hereof, all
shares of Common Stock that are issuable upon conversion, exercise or exchange
of Common Stock Equivalents shall be deemed outstanding immediately after the
issuance of such Common Stock Equivalents. Such adjustment shall be made
whenever such Common Stock or Common Stock Equivalents are issued. However, upon
the expiration of any Common Stock Equivalents the issuance of which resulted in
an adjustment in the Exercise Price pursuant to this Section, if any such Common
Stock Equivalents shall expire and shall not have been exercised, the Exercise
Price shall immediately upon such expiration be recomputed and effective
immediately upon such expiration be increased to the price which it would have
been (but reflecting any other adjustments in the Exercise Price made pursuant
to the provisions of this Section after the issuance of such Common Stock
Equivalents) had the adjustment of the Exercise Price made upon the issuance of
such Common Stock Equivalents been made on the basis of offering for
subscription or purchase only that number of shares of the Common Stock actually
purchased upon the exercise of such Common Stock Equivalents actually exercised.
The foregoing shall not apply to any (i) issuances of securities as
consideration in a merger, consolidation or acquisition of assets, or in
connection with any strategic partnership or joint venture (the primary purpose
of which is not to raise equity capital), or as consideration for the
acquisition

                                       5

<PAGE>   83
of a business, product or license by the Company, (ii) the issuance of
securities upon the exercise or conversion of the Company's options, warrants or
other convertible securities outstanding as of the date hereof, or (iii) the
grant of options or warrants, or the issuance of additional securities, under
any duly authorized Company stock option, restricted stock plan or stock
purchase plan for the benefit of the Company's employees.

         (e) Except as contemplated by the Merger Agreement (as defined in the
Purchase Agreement) in case of any (1) merger or consolidation of the Company
with or into another Person, or (2) sale by the Company of more than one-half of
the assets of the Company (based upon then fair market value) in one or a series
of related transactions, (A) the Holder shall have the right at all times from
and after the date of such merger, sale or consolidation, as the case may be, to
and including the Expiration Date, to exercise this Warrant for the shares of
stock and other securities, cash and property receivable upon or deemed to be
held by holders of Common Stock immediately following such merger, consolidation
or sale, and the Holder shall be entitled upon such event or series of related
events to receive such amount of securities, cash and property as the Common
Stock for which this Warrant could have been exercised immediately prior to such
merger, consolidation or sales would have been entitled, or (B) the acquiring
company or newly created company shall have the right to pay the Holder the
value of the Warrant determined on a Black-Scholes basis. (For example, if (1)
the Company merges with and into another Person ("Newco") and as a result
thereof each share of Common Stock shall entitle the holder thereof to receive
two shares of the common stock of Newco and $2.00 in cash, and (2) the Exercise
Price is at the effective time of such merger $6.00 per share, then at all times
thereafter this Warrant shall upon the payment of $6.00 times the number of
Warrant Shares represent the right to receive (A) that number of shares of the
Common Stock of Newco as is equal to two times the Warrant Shares, and (B) that
amount of cash as is equal to $2.00 times the number of Warrant Shares.) The
terms of any such merger, sale or consolidation shall include such terms so as
to continue to give the Holder the right to receive the securities, cash and
property set forth in this Section upon any conversion or redemption following
such event. This provision shall similarly apply to successive such events.

         (f) For the purposes of this Section 7, the following clauses shall
also be applicable:

             (i) Record Date. In case the Company shall take a record of the
holders of its Common Stock for the purpose of entitling them (A) to receive a
dividend or other distribution payable in Common Stock or in securities
convertible or exchangeable into shares of Common Stock, or (B) to subscribe for
or purchase Common Stock or securities convertible or exchangeable into shares
of Common Stock, then such record date shall be deemed to be the date of the
issue or sale of the shares of Common Stock deemed to have been issued or sold
upon the declaration of such dividend or the making of such other distribution
or the date of the granting of such right of subscription or purchase, as the
case may be.

             (ii) Treasury Shares. The number of shares of Common Stock
outstanding at any given time shall not include shares owned or held by or for
the account of

                                       6

<PAGE>   84
the Company, and the disposition of any such shares shall be considered an issue
or sale of Common Stock.

         (g) All calculations under this Section 7 shall be made to the nearest
cent or the nearest 1/100th of a share, as the case may be.

         (h) Whenever the Exercise Price is adjusted pursuant to Section 7(c)
above, the Holder, after receipt of the determination by the Appraiser, shall
have the right to select an additional appraiser (which shall be a nationally
recognized accounting firm), in which case the adjustment shall be equal to the
average of the adjustments recommended by each of the Appraiser and such
appraiser. The Holder shall promptly mail or cause to be mailed to the Company,
a notice setting forth the Exercise Price after such adjustment and setting
forth a brief statement of the facts requiring such adjustment. Such adjustment
shall become effective immediately after the record date mentioned above.

         (i) If:

                  (i)      the Company shall declare a dividend (or any other
                           distribution) on its Common Stock; or

                  (ii)     the Company shall declare a special nonrecurring cash
                           dividend on or a redemption of its Common Stock; or

                  (iii)    the Company shall authorize the granting to all
                           holders of the Common Stock rights or warrants to
                           subscribe for or purchase any shares of capital stock
                           of any class or of any rights; or

                  (iv)     the approval of any stockholders of the Company shall
                           be required in connection with any reclassification
                           of the Common Stock, any consolidation or merger to
                           which the Company is a party, any sale or transfer of
                           all or substantially all of the assets of the
                           Company, or any compulsory share exchange whereby the
                           Common Stock is converted into other securities, cash
                           or property; or

                  (v)      the Company shall authorize the voluntary
                           dissolution, liquidation or winding up of the affairs
                           of the Company,

then the Company shall cause to be mailed to each Holder at their last addresses
as they shall appear upon the Warrant Register, at least twenty calendar days
prior to the applicable record or effective date hereinafter specified, a notice
stating (x) the date on which a record is to be taken for the purpose of such
dividend, distribution, redemption, rights or warrants, or if a record is not to
be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distributions, redemption, rights or warrants are to
be determined or

                                       7
<PAGE>   85
(y) the date on which such reclassification, consolidation, merger, sale,
transfer or share exchange is expected to become effective or close, and the
date as of which it is expected that holders of Common Stock of record shall be
entitled to exchange their shares of Common Stock for securities, cash or other
property deliverable upon such reclassification, consolidation, merger, sale,
transfer, share exchange, dissolution, liquidation or winding up; provided,
however, that the failure to mail such notice or any defect therein or in the
mailing thereof shall not affect the validity of the corporate action required
to be specified in such notice.

    8.   Payment of Exercise Price. The Holder shall pay the Exercise Price in
one of the following manners:

         (a) Cash Exercise. The Holder may deliver immediately available funds;
or

         (b) Cashless Exercise. In the event, but only in such event, that on or
after the Effective Date (as defined in the Purchase Agreement) a Registration
Statement covering the resale of the Warrant Shares has not been declared
effective, then the Holder may surrender this Warrant to the Company together
with a notice of cashless exercise, in which event the Company shall issue to
the Holder the number of Warrant Shares determined as follows:

                                            X = Y [(A-B)/A]

         where:

                                            X = the number of Warrant Shares to
                                            be issued to the Holder.

                                            Y = the number of Warrant Shares
                                            with respect to which this Warrant
                                            is being exercised.

                                            A = the average of the closing sale
                                            prices of the Common Stock for the
                                            five (5) trading days immediately
                                            prior to (but not including) the
                                            Date of Exercise.

                                            B = the Exercise Price.

For purposes of Rule 144 promulgated under the Securities Act, it is intended,
understood and acknowledged that the Warrant Shares issued in a cashless
exercise transaction shall be deemed to have been acquired by the Holder, and
the holding period for the Warrant Shares shall be deemed to have been
commenced, on the issue date.

    9.   Certain Exercise Restrictions.

                                       8

<PAGE>   86
         (a) A Holder may not exercise this Warrant to the extent such exercise
would result in the Holder, together with any affiliate thereof, beneficially
owning (as determined in accordance with Section 13(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act") and the rules promulgated
thereunder) in excess of 4.999% of the then issued and outstanding shares of
Common Stock, including shares issuable upon such exercise and held by such
Holder after application of this Section. Since the Holder will not be obligated
to report to the Company the number of shares of Common Stock it may hold at the
time of an exercise hereunder, unless the exercise at issue would result in the
issuance of shares of Common Stock in excess of 4.999% of the then outstanding
shares of Common Stock without regard to any other shares which may be
beneficially owned by the Holder or an affiliate thereof, the Holder shall have
the authority and obligation to determine whether the restriction contained in
this Section will limit any particular exercise hereunder and to the extent that
the Holder determines that the limitation contained in this Section applies, the
determination of which portion of this Warrant is exercisable shall be the
responsibility and obligation of the Holder. If the Holder has delivered a Form
of Election to Purchase for a number of Warrant Shares that, without regard to
any other shares that the Holder or its affiliates may beneficially own, would
result in the issuance in excess of the permitted amount hereunder, the Company
shall notify the Holder of this fact and shall honor the exercise for the
maximum portion of this Warrant permitted to be exercised on such Date of
Exercise in accordance with the periods described herein and, at the option of
the Holder, either keep the portion of the Warrant tendered for exercise in
excess of the permitted amount hereunder for future exercises or return such
excess portion of the Warrant to the Holder. The provisions of this Section may
be waived by a Holder (but only as to itself and not to any other Holder) upon
not less than sixty-one days prior notice to the Company. Other Holders shall be
unaffected by any such waiver.

         (b) A Holder may not exercise this Warrant to the extent such exercise
would result in the Holder, together with any affiliate thereof, beneficially
owning (as determined in accordance with Section 13(d) of the Exchange Act and
the rules promulgated thereunder) in excess of 9.999% of the then issued and
outstanding shares of Common Stock, including shares issuable upon such exercise
and held by such Holder after application of this Section. Since the Holder will
not be obligated to report to the Company the number of shares of Common Stock
it may hold at the time of an exercise hereunder, unless the exercise at issue
would result in the issuance of shares of Common Stock in excess of 9.999% of
the then outstanding shares of Common Stock without regard to any other shares
which may be beneficially owned by the Holder or an affiliate thereof, the
Holder shall have the authority and obligation to determine whether the
restriction contained in this Section will limit any particular exercise
hereunder and to the extent that the Holder determines that the limitation
contained in this Section applies, the determination of which portion of this
Warrant is exercisable shall be the responsibility and obligation of the Holder.
If the Holder has delivered a Form of Election to Purchase for a number of
Warrant Shares that, without regard to any other shares that the Holder or its
affiliates may beneficially own, would result in the issuance in excess of the
permitted amount hereunder, the Company shall notify the Holder of this fact and
shall honor the exercise for the maximum portion of this Warrant permitted to be
exercised on such Date of Exercise in accordance with the periods described
herein and, at the option of

                                       9

<PAGE>   87
the Holder, either keep the portion of the Warrant tendered for exercise in
excess of the permitted amount hereunder for future exercises or return such
excess portion of the Warrant to the Holder. The provisions of this Section may
be waived by a Holder (but only as to itself and not to any other Holder) upon
not less than sixty-one days prior notice to the Company. Other Holders shall be
unaffected by any such waiver.

    10. Fractional Shares. The Company shall not be required to issue or cause
to be issued fractional Warrant Shares on the exercise of this Warrant. The
number of full Warrant Shares which shall be issuable upon the exercise of this
Warrant shall be computed on the basis of the aggregate number of Warrant Shares
purchasable on exercise of this Warrant so presented. If any fraction of a
Warrant Share would, except for the provisions of this Section, be issuable on

                                     WARRANT

Warrant No. _______

Dated:   July 27, 2000

    Eltrax Systems, Inc., a Minnesota corporation (the "Company"), hereby
certifies that, for value received, [ ] or its registered assigns ("Holder"), is
entitled, subject to the terms set forth below, to purchase from the Company up
to a total of 104,1681 shares of common stock, $.01 par value per share (the
"Common Stock"), of the Company (each such share, a "Warrant Share" and all such
shares, the "Warrant Shares"). The initial "Exercise Price" for Warrant Shares
shall be $5.03, and shall be subject to adjustment from time to time as provided
in Section 7. The Holder may acquire Warrant Shares under this Warrant at such
times as is provided for in Section 3(a) hereof.

    This Warrant shall be subject to the following terms and conditions:

    1.   Registration of Warrant. The Company shall register this Warrant, upon
records to be maintained by the Company for that purpose (the "Warrant
Register"), in the name of the record Holder hereof from time to time. The
Company may deem and treat the registered Holder of this Warrant as the absolute
owner hereof for the purpose of any exercise hereof or any distribution to the
Holder, and for all other purposes, and the Company shall not be affected by
notice to the contrary.

    2.   Registration of Transfers and Exchanges.

         (a)   The Company shall register the transfer of any portion of this
Warrant in the Warrant Register, upon surrender of this Warrant, with the Form
of Assignment attached

____________________

<PAGE>   95

hereto duly completed and signed, to the Transfer Agent or to the Company at its
address for notice set forth in Section 11. Upon any such registration or
transfer, a new warrant to purchase Common Stock, in substantially the form of
this Warrant (any such new warrant, a "New Warrant"), evidencing the portion of
this Warrant so transferred shall be issued to the transferee and a New Warrant
evidencing the remaining portion of this Warrant not so transferred, if any,
shall be issued to the transferring Holder. The acceptance of the New Warrant by
the transferee thereof shall be deemed the acceptance of such transferee of all
of the rights and obligations of a holder of a Warrant.

         (b)   This Warrant is exchangeable, upon the surrender hereof by the
Holder to the office of the Company at its address for notice set forth in
Section 11 for one or more New Warrants, evidencing in the aggregate the right
to purchase the number of Warrant Shares which may then be purchased hereunder.
Any such New Warrant will be dated the date of such exchange.

         (c)   This Warrant has been issued subject to certain investment
representations of the original Holder set forth in the Convertible Debenture
Purchase Agreement among the Company and the Holder dated as of July 27, 2000
(the "Purchase Agreement") and may only be transferred or exchanged in
compliance with the transfer restrictions contained therein.

    3.   Duration and Exercise of Warrants.

         (a)   This Warrant shall be exercisable by the registered Holder on any
business day before 6:30 P.M., New York City time, and from time to time from
and after the earliest to occur of (a) one hundred fifty days after the Initial
Closing Date (as such term is defined in Section 1.2 of the Purchase Agreement,
or (b) the Third Closing Date (as such term is defined in Section 1.3 of the
Purchase Agreement), and through and including July 26, 2005 (the "Expiration
Date").; provided, however, that this Warrant shall be null and void ab initio,
and of no force and effect in the event the Holder breaches its obligation to
purchase the Third Tranche Debentures as contemplated by the Purchase Agreement.
At 6:30 P.M., New York City time on the Expiration Date, the portion of this
Warrant not exercised prior thereto shall be and become void and of no value.
Prior to the Expiration Date, the Company may not call or otherwise redeem this
Warrant without the prior written consent of the Holder.

         (b)   Upon surrender of this Warrant, with the Form of Election to
Purchase attached hereto duly completed and signed, to the Company at its
address for notice set forth in Section 12 and upon payment of the Exercise
Price multiplied by the number of Warrant Shares that the Holder intends to
purchase hereunder, in the manner provided hereunder, all as specified by the
Holder in the Form of Election to Purchase, the Company shall promptly (but in
no event later than three business days after the Date of Exercise (as defined
herein)) issue or cause to be issued and cause to be delivered to or upon the
written order of the Holder and in such name or names as the Holder may
designate, a certificate for the Warrant Shares issuable upon such exercise,
free of restrictive legends except (i) either in the event that a registration
statement covering the resale of the Warrant Shares and naming the Holder as a

                                       2

<PAGE>   96

selling stockholder thereunder is not then effective or the Warrant Shares are
not freely transferable without volume restrictions pursuant to Rule 144(k)
promulgated under the Securities Act of 1933, as amended (the "Securities Act"),
or (ii) if this Warrant shall have been issued pursuant to a written agreement
between the original Holder and the Company, as required by such agreement. Any
person so designated by the Holder to receive Warrant Shares shall be deemed to
have become holder of record of such Warrant Shares as of the Date of Exercise
of this Warrant. The Company shall, upon request of the Holder, if available,
use its best efforts to deliver Warrant Shares hereunder electronically through
the Depository Trust Corporation or another established clearing corporation
performing similar functions.

         (c)   A "Date of Exercise" means the date on which the Company shall
have received (i) this Warrant (or any New Warrant, as applicable), with the
Form of Election to Purchase attached hereto (or attached to such New Warrant)
appropriately completed and duly signed, and (ii) payment of the Exercise Price
for the number of Warrant Shares so indicated by the Holder hereof to be
purchased.

         (d)   This Warrant shall be exercisable, either in its entirety or,
from time to time, for a portion of the number of Warrant Shares, representing
not less than 10% of the original Warrant Shares or such lesser amount as is
then remaining available for exercise. If less than all of the Warrant Shares
which may be purchased under this Warrant are exercised at any time, the Company
shall issue or cause to be issued, at its expense, a New Warrant evidencing the
right to purchase the remaining number of Warrant Shares for which no exercise
has been evidenced by this Warrant.

    4.   Payment of Taxes. The Company will pay all documentary stamp taxes
attributable to the issuance of Warrant Shares upon the exercise of this
Warrant; provided, however, that the Company shall not be required to pay any
tax which may be payable in respect of any transfer involved in the registration
of any certificates for Warrant Shares or Warrants in a name other than that of
the Holder. The Holder shall be responsible for all other tax liability that may
arise as a result of holding or transferring this Warrant or receiving Warrant
Shares upon exercise hereof.

    5.   Replacement of Warrant. If this Warrant is mutilated, lost, stolen or
destroyed, the Company shall issue or cause to be issued in exchange and
substitution for and upon cancellation hereof, or in lieu of and substitution
for this Warrant, a New Warrant, but only upon receipt of evidence reasonably
satisfactory to the Company of such loss, theft or destruction and indemnity, if
requested, satisfactory to it. Applicants for a New Warrant under such
circumstances shall also comply with such other reasonable regulations and
procedures and pay such other reasonable charges as the Company may prescribe.

    6.   Reservation of Warrant Shares. The Company covenants that it will at
all times reserve and keep available out of the aggregate of its authorized but
unissued Common Stock, solely for the purpose of enabling it to issue Warrant
Shares upon exercise of this Warrant as herein provided, the number of Warrant
Shares which are then issuable and deliverable upon the exercise of this entire
Warrant, free from preemptive rights or any other actual contingent

                                       3

<PAGE>   97

purchase rights of persons other than the Holder (taking into account the
adjustments and restrictions of Section 7). The Company covenants that all
Warrant Shares that shall be so issuable and deliverable shall, upon issuance
and the payment of the applicable Exercise Price in accordance with the terms
hereof, be duly and validly authorized, issued and fully paid and nonassessable.

    7.   Certain Adjustments. The Exercise Price and number of Warrant Shares
issuable upon exercise of this Warrant are subject to adjustment from time to
time as set forth in this Section 7. Upon each such adjustment of the Exercise
Price pursuant to this Section 7, the Holder shall thereafter prior to the
Expiration Date be entitled to purchase, at the Exercise Price resulting from
such adjustment, the number of Warrant Shares obtained by multiplying the
Exercise Price in effect immediately prior to such adjustment by the number of
Warrant Shares issuable upon exercise of this Warrant immediately prior to such
adjustment and dividing the product thereof by the Exercise Price resulting from
such adjustment.

         (a)   If the Company, at any time while this Warrant is outstanding,
(i) shall pay a stock dividend (except scheduled dividends paid on preferred
stock which contain a stated dividend rate) or otherwise make a distribution or
distributions on shares of its Common Stock or on any other class of capital
stock payable in shares of Common Stock, (ii) subdivide outstanding shares of
Common Stock into a larger number of shares, or (iii) combine outstanding shares
of Common Stock into a smaller number of shares, the Exercise Price shall be
multiplied by a fraction of which the numerator shall be the number of shares of
Common Stock (excluding treasury shares, if any) outstanding before such event
and of which the denominator shall be the number of shares of Common Stock
(excluding treasury shares, if any) outstanding after such event. Any adjustment
made pursuant to this Section shall become effective immediately after the
record date for the determination of stockholders entitled to receive such
dividend or distribution and shall become effective immediately after the
effective date in the case of a subdivision or combination, and shall apply to
successive subdivisions and combinations.

         (b)   In case of any reclassification of the Common Stock or any
compulsory share exchange pursuant to which the Common Stock is converted into
other securities, cash or property, then the Holder shall have the right
thereafter to exercise this Warrant only into the shares of stock and other
securities and property receivable upon or deemed to be held by holders of
Common Stock following such reclassification or share exchange, and the Holder
shall be entitled upon such event to receive such amount of securities or
property equal to the amount of Warrant Shares such Holder would have been
entitled to had such Holder exercised this Warrant immediately prior to such
reclassification or share exchange. The terms of any such reclassification or
share exchange shall include such terms so as to continue to give to the Holder
the right to receive the securities or property set forth in this Section 7(b)
upon any exercise following any such reclassification or share exchange.

         (c)   If the Company, at any time while this Warrant is outstanding,
shall distribute to all holders of Common Stock (and not to holders of this
Warrant) evidences of its indebtedness or assets or rights or warrants to
subscribe for or purchase any security

                                       4

<PAGE>   98

(excluding those referred to in Sections 7(a), (b) and (d)), then in each such
case the Exercise Price shall be determined by multiplying the Exercise Price in
effect immediately prior to the record date fixed for determination of
stockholders entitled to receive such distribution by a fraction of which the
denominator shall be the Exercise Price determined as of the record date
mentioned above, and of which the numerator shall be such Exercise Price on such
record date less the then fair market value at such record date of the portion
of such assets or evidence of indebtedness so distributed applicable to one
outstanding share of Common Stock as determined by the Company's independent
certified public accountants that regularly examines the financial statements of
the Company (an "Appraiser").

         (d)   If the Company or any subsidiary thereof, as applicable with
respect to Common Stock Equivalents (as defined below), at any time while this
Warrant is outstanding, shall issue shares of Common Stock or rights, warrants,
options or other securities or debt that is convertible into or exchangeable for
shares of Common Stock ("Common Stock Equivalents"), entitling any person to
acquire shares of Common Stock at a price per share less than the Exercise Price
(if the holder of the Common Stock or Common Stock Equivalent so issued shall at
any time, whether by operation of purchase price adjustments, reset provisions,
floating conversion, exercise or exchange prices or otherwise, or due to
warrants, options or rights issued in connection with such issuance, be entitled
to receive shares of Common Stock at a price less than the Exercise Price, such
issuance shall be deemed to have occurred for less than the Exercise Price),
then the Exercise Price shall be multiplied by a fraction, the numerator of
which shall be the number of shares of Common Stock outstanding immediately
prior to the issuance of such Common Stock or such Common Stock Equivalents plus
the number of shares of Common Stock which the offering price for such shares of
Common Stock or Common Stock Equivalents would purchase at the Exercise Price,
and the denominator of which shall be the sum of the number of shares of Common
Stock outstanding immediately prior to such issuance plus the number of shares
of Common Stock so issued or issuable, provided, that for purposes hereof, all
shares of Common Stock that are issuable upon conversion, exercise or exchange
of Common Stock Equivalents shall be deemed outstanding immediately after the
issuance of such Common Stock Equivalents. Such adjustment shall be made
whenever such Common Stock or Common Stock Equivalents are issued. However, upon
the expiration of any Common Stock Equivalents the issuance of which resulted in
an adjustment in the Exercise Price pursuant to this Section, if any such Common
Stock Equivalents shall expire and shall not have been exercised, the Exercise
Price shall immediately upon such expiration be recomputed and effective
immediately upon such expiration be increased to the price which it would have
been (but reflecting any other adjustments in the Exercise Price made pursuant
to the provisions of this Section after the issuance of such Common Stock
Equivalents) had the adjustment of the Exercise Price made upon the issuance of
such Common Stock Equivalents been made on the basis of offering for
subscription or purchase only that number of shares of the Common Stock actually
purchased upon the exercise of such Common Stock Equivalents actually exercised.
The foregoing shall not apply to any (i) issuances of securities as
consideration in a merger, consolidation or acquisition of assets, or in
connection with any strategic partnership or joint venture (the primary purpose
of which is not to raise equity capital), or as consideration for the
acquisition of a business, product or license by the Company, (ii) the issuance
of securities upon the

                                       5

<PAGE>   99

exercise or conversion of the Company's options, warrants or other convertible
securities outstanding as of the date hereof, or (iii) the grant of options or
warrants, or the issuance of additional securities, under any duly authorized
Company stock option, restricted stock plan or stock purchase plan for the
benefit of the Company's employees.

         (e)   Except as contemplated by the Merger Agreement (as defined in the
Purchase Agreement) in case of any (1) merger or consolidation of the Company
with or into another Person, or (2) sale by the Company of more than one-half of
the assets of the Company (based upon then fair market value) in one or a series
of related transactions, (A) the Holder shall have the right at all times from
and after the date of such merger, sale or consolidation, as the case may be, to
and including the Expiration Date, to exercise this Warrant for the shares of
stock and other securities, cash and property receivable upon or deemed to be
held by holders of Common Stock immediately following such merger, consolidation
or sale, and the Holder shall be entitled upon such event or series of related
events to receive such amount of securities, cash and property as the Common
Stock for which this Warrant could have been exercised immediately prior to such
merger, consolidation or sales would have been entitled, or (B) the acquiring
company or newly created company shall have the right to pay the Holder the
value of the Warrant determined on a Black-Scholes basis. (For example, if (1)
the Company merges with and into another Person ("Newco") and as a result
thereof each share of Common Stock shall entitle the holder thereof to receive
two shares of the common stock of Newco and $2.00 in cash, and (2) the Exercise
Price is at the effective time of such merger $6.00 per share, then at all times
thereafter this Warrant shall upon the payment of $6.00 times the number of
Warrant Shares represent the right to receive (A) that number of shares of the
Common Stock of Newco as is equal to two times the Warrant Shares, and (B) that
amount of cash as is equal to $2.00 times the number of Warrant Shares.) The
terms of any such merger, sale or consolidation shall include such terms so as
to continue to give the Holder the right to receive the securities, cash and
property set forth in this Section upon any conversion or redemption following
such event. This provision shall similarly apply to successive such events.

         (f)   For the purposes of this Section 7, the following clauses shall
also be applicable:

               (i)   Record Date. In case the Company shall take a record of the
holders of its Common Stock for the purpose of entitling them (A) to receive a
dividend or other distribution payable in Common Stock or in securities
convertible or exchangeable into shares of Common Stock, or (B) to subscribe for
or purchase Common Stock or securities convertible or exchangeable into shares
of Common Stock, then such record date shall be deemed to be the date of the
issue or sale of the shares of Common Stock deemed to have been issued or sold
upon the declaration of such dividend or the making of such other distribution
or the date of the granting of such right of subscription or purchase, as the
case may be.

               (ii)  Treasury Shares. The number of shares of Common Stock
outstanding at any given time shall not include shares owned or held by or for
the account of

                                       6

<PAGE>   100

the Company, and the disposition of any such shares shall be considered an issue
or sale of Common Stock.

         (g)   All calculations under this Section 7 shall be made to the
nearest cent or the nearest 1/100th of a share, as the case may be.

         (h)   Whenever the Exercise Price is adjusted pursuant to Section 7(c)
above, the Holder, after receipt of the determination by the Appraiser, shall
have the right to select an additional appraiser (which shall be a nationally
recognized accounting firm), in which case the adjustment shall be equal to the
average of the adjustments recommended by each of the Appraiser and such
appraiser. The Holder shall promptly mail or cause to be mailed to the Company,
a notice setting forth the Exercise Price after such adjustment and setting
forth a brief statement of the facts requiring such adjustment. Such adjustment
shall become effective immediately after the record date mentioned above.

         (i)   If:

                      (i)   the Company shall declare a dividend (or any other
                            distribution) on its Common Stock; or

                      (ii)  the Company shall declare a special nonrecurring
                            cash dividend on or a redemption of its Common
                            Stock; or

                      (iii) the Company shall authorize the granting to all
                            holders of the Common Stock rights or warrants to
                            subscribe for or purchase any shares of capital
                            stock of any class or of any rights; or

                      (iv)  the approval of any stockholders of the Company
                            shall be required in connection with any
                            reclassification of the Common Stock, any
                            consolidation or merger to which the Company is a
                            party, any sale or transfer of all or substantially
                            all of the assets of the Company, or any compulsory
                            share exchange whereby the Common Stock is converted
                            into other securities, cash or property; or

                      (v)   the Company shall authorize the voluntary
                            dissolution, liquidation or winding up of the
                            affairs of the Company,

then the Company shall cause to be mailed to each Holder at their last addresses
as they shall appear upon the Warrant Register, at least twenty calendar days
prior to the applicable record or effective date hereinafter specified, a notice
stating (x) the date on which a record is to be taken for the purpose of such
dividend, distribution, redemption, rights or warrants, or if a record is not to
be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distributions, redemption, rights or warrants are to
be determined or

                                       7
<PAGE>   101

(y) the date on which such reclassification, consolidation, merger, sale,
transfer or share exchange is expected to become effective or close, and the
date as of which it is expected that holders of Common Stock of record shall be
entitled to exchange their shares of Common Stock for securities, cash or other
property deliverable upon such reclassification, consolidation, merger, sale,
transfer, share exchange, dissolution, liquidation or winding up; provided,
however, that the failure to mail such notice or any defect therein or in the
mailing thereof shall not affect the validity of the corporate action required
to be specified in such notice.

    8.   Payment of Exercise Price. The Holder shall pay the Exercise Price in
one of the following manners:

         (a)   Cash Exercise. The Holder may deliver immediately available
funds; or

         (b)   Cashless Exercise. In the event, but only in such event, that on
or after the Effective Date (as defined in the Purchase Agreement) a
Registration Statement covering the resale of the Warrant Shares has not been
declared effective, then the Holder may surrender this Warrant to the Company
together with a notice of cashless exercise, in which event the Company shall
issue to the Holder the number of Warrant Shares determined as follows:

                             X = Y [(A-B)/A]

    where:

                             X = the number of Warrant Shares to be issued to
                             the Holder.

                             Y = the number of Warrant Shares with respect to
                             which this Warrant is being exercised.

                             A = the average of the closing sale prices of the
                             Common Stock for the five (5) trading days
                             immediately prior to (but not including) the Date
                             of Exercise.

                             B = the Exercise Price.

For purposes of Rule 144 promulgated under the Securities Act, it is intended,
understood and acknowledged that the Warrant Shares issued in a cashless
exercise transaction shall be deemed to have been acquired by the Holder, and
the holding period for the Warrant Shares shall be deemed to have been
commenced, on the issue date.

    9.   Certain Exercise Restrictions.

                                       8
<PAGE>   102

         (a)   A Holder may not exercise this Warrant to the extent such
exercise would result in the Holder, together with any affiliate thereof,
beneficially owning (as determined in accordance with Section 13(d) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act") and the rules
promulgated thereunder) in excess of 4.999% of the then issued and outstanding
shares of Common Stock, including shares issuable upon such exercise and held by
such Holder after application of this Section. Since the Holder will not be
obligated to report to the Company the number of shares of Common Stock it may
hold at the time of an exercise hereunder, unless the exercise at issue would
result in the issuance of shares of Common Stock in excess of 4.999% of the then
outstanding shares of Common Stock without regard to any other shares which may
be beneficially owned by the Holder or an affiliate thereof, the Holder shall
have the authority and obligation to determine whether the restriction contained
in this Section will limit any particular exercise hereunder and to the extent
that the Holder determines that the limitation contained in this Section
applies, the determination of which portion of this Warrant is exercisable shall
be the responsibility and obligation of the Holder. If the Holder has delivered
a Form of Election to Purchase for a number of Warrant Shares that, without
regard to any other shares that the Holder or its affiliates may beneficially
own, would result in the issuance in excess of the permitted amount hereunder,
the Company shall notify the Holder of this fact and shall honor the exercise
for the maximum portion of this Warrant permitted to be exercised on such Date
of Exercise in accordance with the periods described herein and, at the option
of the Holder, either keep the portion of the Warrant tendered for exercise in
excess of the permitted amount hereunder for future exercises or return such
excess portion of the Warrant to the Holder. The provisions of this Section may
be waived by a Holder (but only as to itself and not to any other Holder) upon
not less than sixty-one days prior notice to the Company. Other Holders shall be
unaffected by any such waiver.

         (b)   A Holder may not exercise this Warrant to the extent such
exercise would result in the Holder, together with any affiliate thereof,
beneficially owning (as determined in accordance with Section 13(d) of the
Exchange Act and the rules promulgated thereunder) in excess of 9.999% of the
then issued and outstanding shares of Common Stock, including shares issuable
upon such exercise and held by such Holder after application of this Section.
Since the Holder will not be obligated to report to the Company the number of
shares of Common Stock it may hold at the time of an exercise hereunder, unless
the exercise at issue would result in the issuance of shares of Common Stock in
excess of 9.999% of the then outstanding shares of Common Stock without regard
to any other shares which may be beneficially owned by the Holder or an
affiliate thereof, the Holder shall have the authority and obligation to
determine whether the restriction contained in this Section will limit any
particular exercise hereunder and to the extent that the Holder determines that
the limitation contained in this Section applies, the determination of which
portion of this Warrant is exercisable shall be the responsibility and
obligation of the Holder. If the Holder has delivered a Form of Election to
Purchase for a number of Warrant Shares that, without regard to any other shares
that the Holder or its affiliates may beneficially own, would result in the
issuance in excess of the permitted amount hereunder, the Company shall notify
the Holder of this fact and shall honor the exercise for the maximum portion of
this Warrant permitted to be exercised on such Date of Exercise in accordance
with the periods described herein and, at the option of

                                       9

<PAGE>   103

the Holder, either keep the portion of the Warrant tendered for exercise in
excess of the permitted amount hereunder for future exercises or return such
excess portion of the Warrant to the Holder. The provisions of this Section may
be waived by a Holder (but only as to itself and not to any other Holder) upon
not less than sixty-one days prior notice to the Company. Other Holders shall be
unaffected by any such waiver.

    10.  Fractional Shares. The Company shall not be required to issue or cause
to be issued fractional Warrant Shares on the exercise of this Warrant. The
number of full Warrant Shares which shall be issuable upon the exercise of this
Warrant shall be computed on the basis of the aggregate number of Warrant Shares
purchasable on exercise of this Warrant so presented. If any fraction of a
Warrant Share would, except for the provisions of this Section, be issuable on
the exercise of this Warrant, the Company shall pay an amount in cash equal to
the Exercise Price multiplied by such fraction.

    11.  Notices. Any and all notices or other communications or deliveries
hereunder shall be in writing and shall be deemed given and effective on the
earliest of (i) the date of transmission, if such notice or communication is
delivered via facsimile at the facsimile telephone number specified in this
Section prior to 6:30 p.m. (New York City time) on a business day, (ii) the
business day after the date of transmission, if such notice or communication is
delivered via facsimile at the facsimile telephone number specified in this
Section later than 6:30 p.m. (New York City time) on any date and earlier than
11:59 p.m. (New York City time) on such date, (iii) the business day following

Warrant. Upon thirty days' notice to the Holder, the Company may appoint a new

may be merged or any corporation resulting from any consolidation to which the
Company or any new warrant agent shall be a party or any corporation to which
the Company or any new warrant agent transfers substantially all of its
corporate trust or shareholders services business shall be a successor warrant
agent under this Warrant without any further act. Any such successor warrant
agent shall promptly cause notice of its succession as warrant agent to be

address as shown on the Warrant Register.

    13.  Miscellaneous.

         (a)   This Warrant shall be binding on and inure to the benefit of the
parties hereto and their respective successors and assigns. This Warrant may be
amended only in writing signed by the Company and the Holder and their
successors and assigns.

         (b)   Subject to Section 13(a), above, nothing in this Warrant shall be

         (c)   The corporate laws of the State of Minnesota shall govern all

irrevocably submit to the exclusive jurisdiction of the state and federal courts
sitting in the City of New York, borough of Manhattan, for the adjudication of

(To be executed by the Holder to exercise the right to purchase shares of Common

To Eltrax Systems, Inc.:

    The undersigned hereby irrevocably elects to purchase _____________ shares

    The undersigned requests that certificates for the shares of Common Stock

    Re:  Convertible Debenture Purchase Agreement (the "Agreement"), dated July
         27, 2000, by and between Eltrax Systems, Inc., a Minnesota corporation
         (the "Company"), and the Purchasers (as defined therein)

Dear Sirs/Madames:

    We have acted as special counsel to the Company in connection with the
execution and delivery of the Agreement, and in this capacity, we have examined
and relied upon executed copies of the Agreement and of the Debentures, Warrants
and Registration Rights Agreement attached as Exhibits A, B and D, respectively,
to the Agreement. We have also examined and relied upon a certified copy of the
Articles of Incorporation of the Company and certificate of good standing of the
Company issued by the Secretary of State of the State of Minnesota, a
certificate as to factual matters on information set forth in a certificate of
an officer of the Company ("Certificate") and copies of the organizational
documents, bylaws and minute books for the Company and its subsidiaries provided
to us by management of the Company. All terms in this letter that are
capitalized and have not been defined in this letter shall have the meanings
ascribed to them in the Agreement. We are delivering this opinion to you at the
Company's request and pursuant to the terms of the Agreement.

    In our examination, we have assumed the legal capacity of all natural
persons, the genuineness of all signatures, the authenticity of all documents
submitted to us as originals and the conformity to original documents of
documents submitted to us as certified or photostatic copies. We have also
assumed that all parties to the Agreement other than the Company have all
necessary power and authority to execute, deliver, accept and perform the
Agreement, and that each such party has taken all necessary action so as to
cause such party to be bound by the Agreement, including under the terms of its
governing documents and the laws of the jurisdiction of its formation.

    Our review has been limited to examining the documents described above and
applicable Michigan and federal law. We note that the Company is incorporated
under the

<PAGE>   111
Cavallo Capital
Page 2

State of Minnesota and that its subsidiaries are incorporated or otherwise
organized under the laws of Georgia, Pennsylvania and Florida. In addition, we
note that the Agreement is governed by the laws of the State of New York. We
have made no study or other investigation of the laws, decisions, statutes or
other authorities of Minnesota, Georgia, Pennsylvania, Florida or New York.
Rather, for purposes of our opinions, we have assumed, with your permission,
that the substantive laws of those states are identical to the substantive laws
of the State of Michigan in all respects relevant to such opinions.

    To the extent that any opinion given herein relates to or is dependent upon
factual information, or is expressed in terms of our knowledge or awareness, we
have relied exclusively upon the assumptions and the Certificate. We have not
undertaken to independently verify any such facts or information. In this
regard, our knowledge is limited to the conscious awareness of facts or other
information by: (i) the attorney executing this opinion on behalf of our firm;
(ii) any attorney in our firm who has been actively involved in negotiating the
terms and conditions of the Agreement or preparing this opinion; and (iii)
solely as to information relevant to a particular opinion or confirmation
regarding a particular factual matter, the attorney in our firm who is primarily
responsible for providing the response to the particular opinion or confirmation
addressed in this opinion.

    We express no opinion as to the validity, binding effect or enforceability
of provisions of the Agreement to the extent they contain: (i) choice of law or
forum selection provisions, (ii) waivers by the Company of any statutory or
constitutional rights or remedies, (iii) cumulative remedies to the extent such
cumulative remedies purport to compensate, or would have the effect of
compensating, the party entitled to the benefits thereof in an amount in excess
of the actual loss suffered by such party, (iv) indemnification and contribution
provisions which are against the laws or public policy of the United States or
agencies of the United States or (v) agreements, covenants, remedies, waivers
and the like which purport to give rights to the Purchasers under the Agreement
in respect to any matters described in any of the qualifications in this letter.

    Based solely upon the foregoing, and subject to the qualifications and
limitations set forth herein, we are of the opinion that, as of the date hereof:

    1. The Company is incorporated and is validly existing and in good standing
under the laws of the State of Minnesota. The Company has the corporate power
and corporate authority under the Company's Certificate of Incorporation and the
Minnesota Corporation Law to own and operate its current properties and assets.

    2. Each of the Subsidiaries listed as Direct Subsidiaries on Schedule A
hereto is incorporated and is validly existing under the laws of the state of
its incorporation set forth on Schedule A and each such Direct Subsidiary has
the corporate power and authority under its articles of incorporation and bylaws
and under the applicable corporation law to own and operate its current
properties and assets.

    3. The Company has the corporate power and corporate authority under the
Company's Certificate of Incorporation and the Minnesota Corporation Law to
execute and deliver each of the Transaction Documents and to perform its
obligations thereunder. The execution, delivery and performance as of the date
hereof by the Company of the Transaction Documents have been duly authorized by
all necessary corporate action of the Company.

    4. Each of the Transaction Documents has been duly executed and delivered on
behalf of the Company and constitutes a valid and binding obligation of the
Company, enforceable in accordance with its terms, except as may be limited by
bankruptcy, insolvency, reorganization, moratorium or other laws affecting
creditors' rights (including, without limitation, the effect of statutory and
other law regarding fraudulent conveyances, fraudulent transfers and
preferential transfers) and as may be limited by the exercise of judicial
discretion and the application of principles of equity including, without
limitation, requirements of good faith, fair dealing, conscionability and
materiality (regardless of whether such agreement is considered in a proceeding
in equity or at law).

    5. To our knowledge, except as disclosed in Schedule 2.1(c) to the
Agreement, the Company has not issued any outstanding securities convertible
into or exchangeable for, or outstanding options, warrants or other rights to
purchase or to subscribe for, any shares of stock or other securities of the
Company, other than the Securities. No person or entity, including any holder of
outstanding shares of common stock of the Company, has any preemptive right to
subscribe for any of the Securities under (i) the Minnesota Corporation Law,
(ii) any contract filed as an exhibit to an SEC Document or, (iii) to our
knowledge, any other contract to which the Company is a party.

    6. The Debentures and the Warrants have been duly authorized, and when
issued in accordance with the provisions of the Agreement, will be validly
issued.

    7. The shares of common stock of the Company initially issuable upon
conversion of the Debentures and upon exercise of the Warrants (assuming the
conversion or exercise, as the case may be, on the date hereof) have been duly
authorized and reserved for issuance upon conversion of the Debentures or upon
exercise of the Warrants, as the case may be, and such shares of common stock,
when issued and delivered by the Company upon such conversion or exercise in
accordance with the terms of the Debentures or the Warrants, as the case may be,
will be validly issued, fully paid and nonassessable.

    8. Assuming the accuracy of the Purchasers' representations and warranties
in Section 2.2 of the Agreement, the execution and delivery and performance as
of the date hereof by the Company of the Transaction Documents do not (i)
violate the

<PAGE>   113
Cavallo Capital
Page 4

Minnesota Corporation Law or the Company's Certificate of Incorporation or the
Company's Bylaws, (ii) violate any applicable rule, regulation, order, judgment
or decree of the SEC or any other governmental authority or (iii) breach or
constitute a default under any agreement or contract filed as an exhibit to the
SEC Documents.

    9. Assuming the accuracy of the Purchasers' representations and warranties
in Section 2.2 of the Agreement, no approval or consent of, or registration or
filing with, the SEC or any Minnesota governmental agency is required to be
obtained or made by the Company in connection with the execution and delivery
and performance as of the date hereof by the Company of the Transaction
Documents, other than the Required Approvals.

    10. To our knowledge, the Company has filed all reports required to be filed
by it under Sections 13(a) and 15(d) of the Exchange Act since January 1, 1999.
As of their respective filing dates, the SEC Documents complied in all material
respects as to form with the requirements of the Exchange Act and the rules and
regulations of the SEC promulgated thereunder.

    11. Assuming (i) that each Purchaser is an "accredited investor" as defined
in Rule 501 under the Act and (ii) the accuracy of the Purchasers'
representations, warranties and agreements set forth in Section 2.2 of the
Agreement, each of the sale of the Debentures and the Warrants, the issuance of
the shares of common stock upon conversion of the Debentures and the issuance of
the shares of common stock upon exercise of the Warrants to the Purchasers as
contemplated under the Agreement is exempt from registration under the
Securities Act, as in effect on the date hereof.

    12. Except as set forth in the SEC Documents, to our knowledge, the Company
is not (i) subject to any unsatisfied judgment, order, decree, stipulation or
injunction or (ii) a party to or threatened to be made a party to any complaint,
action, suit, proceeding, hearing or investigation of or in any court or
administrative agency of any federal, state, local or foreign jurisdiction or
before any arbitrator.

    Our opinions are limited to the specific issues addressed and are limited in
all respects to the laws and facts existing on the date of this letter. We do
not purport to be experts on or express any opinion herein concerning any laws
other than the laws of the State of Michigan and Federal law and this opinion is
qualified accordingly.

event prior to the Effective Date, and shall use its best efforts to keep such
Registration Statement continuously effective under the Securities Act until the
earlier of the fifth anniversary of the Closing Date therefor and such time as
all Registrable Securities covered by such Registration Statement have been sold
or may be sold without volume restrictions pursuant to Rule 144(k) as determined
by the counsel to the Company pursuant to a written opinion letter to such
effect, addressed and acceptable to the Company's transfer agent and the
affected Holders (the "Effectiveness Period"), provided, that the Company shall
not be deemed to have used its best efforts to keep the Registration Statement
effective during the Effectiveness Period if it voluntarily takes any action
that would result in the Holders not being able to sell the Registrable
Securities covered by such Registration Statement during the Effectiveness
Period, unless such action is required under applicable law or the Company has

                                       3

<PAGE>   119

filed a post-effective amendment to the Registration Statement and the
Commission has not declared it effective.

         (b)   The Registration Statement shall include a number of shares of
Common Stock equal to no less than the sum of (i) 200% of the number of shares
of Common Stock issuable upon conversion in full of the principal amount of
Debentures issuable pursuant to the Purchase Agreement, and (ii) the number of
shares of Common Stock issuable upon exercise in full of the Warrants.

         (c)   If (a) the Registration Statement is not filed on or prior to the
Filing Date (if the Company files such Registration Statement without affording
the Holder the opportunity to review and comment on the same as required by
Section 3(a) hereof, the Company shall not be deemed to have satisfied this
clause (a)), or (b) the Company fails to file with the Commission a request for
acceleration in accordance with Rule 461 promulgated under the Securities Act
within five days of the date that the Company is notified (orally or in writing,
whichever is earlier) by the Commission that the Registration Statement will not
be "reviewed," or not subject to further review, or (c) the Registration
Statement filed hereunder is not declared effective by the Commission on or
prior to the Effective Date, or (d) after the Registration Statement is filed
with and declared effective by the Commission, such Registration Statement
ceases to be effective as to all Registrable Securities to be covered thereby at
any time prior to the expiration of the Effectiveness Period without being
succeeded within ten days by an amendment to such Registration Statement or by a
subsequent Registration Statement filed with and declared effective by the
Commission, or (e) the Common Stock shall be delisted or suspended from trading
on The Nasdaq National Market ("NASDAQ") or on The New York Stock Exchange, or
Nasdaq Smallcap Market (each, a "Subsequent Market") for more than five Trading
Days (which need not be consecutive days) in any twelve-month period, or (f) the
conversion rights of the Holders pursuant to the Debentures are suspended for
any reason, or (g) an amendment to a Registration Statement is not filed by the
Company with the Commission within ten days of the Commission's notifying the
Company that such amendment is required in order for such Registration Statement
to be declared effective (any such failure or breach being referred to as an
"Event," and for purposes of clauses (a), (c), (f) the date on which such Event
occurs, or for purposes of clause (b) the date on which such five day period is
exceeded, or for purposes of clauses (d) and (g) the date which such ten
day-period is exceeded, or for purposes of clause (e) the date on which such
three day-period is exceeded, being referred to as "Event Date"), then, on the
Event Date and each monthly anniversary thereof until the applicable Event is
cured, the Company shall pay to each Holder 2.0% of the purchase price paid by
such Holder pursuant to the Purchase Agreement, in cash, as liquidated damages
and not as a penalty. Notwithstanding the foregoing, (a) in the event the
Company has and continues to use its best efforts to cause the Registration
Statement to be declared effective, no liquidated damages shall be due for
periods prior to the 110th day following the First Closing Date and (b) the
liquidated damages for the first monthly period after the Effective Date, or any
portion thereof, shall be at the rate of 1% of the purchase price paid by such
Holder pursuant to the Purchase Agreement. If the Company fails to pay any
liquidated damages pursuant to this Section in full within five days after the
date payable, the Company will pay interest thereon at a rate of 18% per annum
(or

                                       4

<PAGE>   120

such lesser maximum amount that is permitted to be paid by applicable law) to
the Holder, accruing daily from the date such liquidated damages are due until
such amounts, plus all such interest thereon, are paid in full. The liquidated
damages pursuant to the terms hereof shall apply on a pro-rata basis for any
portion of a month prior to the cure of an Event.

         (d)   Notwithstanding the foregoing, the Company may suspend offers and
sales or delay the effectiveness of any Registration Statement, an aggregate of
up to sixty Trading Days in any 12-month period, if the Company's Board of
Directors determines, in good faith, that such delay would be necessary to avoid
premature disclosure of any material acquisition, disposition, business
combination, or other material transaction, and such delay or suspension will
not result in an Event hereunder (however, no such delay will provide the basis
for avoidance of an Event of Default under Section 3(a)(viii) of the
Debentures).

    3.   Registration Procedures

         In connection with the Company's registration obligations hereunder,
the Company shall:

         (a)   Not less than five Business Days prior to the filing of the
Registration Statement or any related Prospectus or any amendment or supplement
thereto, the Company shall, (i) furnish to the Holders and their Special Counsel
copies of all such documents proposed to be filed, which documents (other than
those incorporated or deemed to be incorporated by reference) will be subject to
the review of such Holders and their Special Counsel, and (ii) cause its
officers and directors, counsel and independent certified public accountants to
respond to such inquiries as shall be necessary, in the reasonable opinion of
Special Counsel to conduct a reasonable investigation within the meaning of the
Securities Act. The Company shall not file a Registration Statement or any such
Prospectus or any amendments or supplements thereto to which the Holders of a
majority of the Registrable Securities to be covered thereby and their Special
Counsel shall reasonably object.

         (b)   (i) Prepare and file with the Commission such amendments,
including post-effective amendments, to the Registration Statement and the
Prospectus used in connection therewith as may be necessary to keep such
Registration Statement continuously effective for the Effectiveness Period; (ii)
cause the related Prospectus to be amended or supplemented by any required
Prospectus supplement, and as so supplemented or amended to be filed pursuant to
Rule 424; (iii) respond as promptly as reasonably possible, and in any event
within ten days, to any comments received from the Commission with respect to
the Registration Statement or any amendment thereto and as promptly as
reasonably possible provide the Holders true and complete copies of all
correspondence from and to the Commission relating to the Registration
Statement; and (iv) comply in all material respects with the provisions of the
Securities Act and the Exchange Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement during the
Effectiveness Period in accordance with the intended methods of disposition by
the Holders thereof set forth in the Registration Statement as so amended or in
such Prospectus as so supplemented.

                                       5

<PAGE>   121

         (c)   File additional Registration Statements if the number of
Registrable Securities to be covered by a Registration Statement at any time
exceeds 85% of the number of shares of Common Stock then registered in such
Registration Statement. The Company shall have twenty days to file such
additional Registration Statements after such requirement notice is received by
the Company (which shall be the Filing Date for such additional Registration
Statements) and the Effectiveness Date for each such additional Registration
Statement shall be the 90th day following the date of such notice.

         (d)   Notify the Holders Special Counsel as promptly as reasonably
possible (and, in the case of (i)(A) below, not less than five Business Days
prior to such filing) and (if requested by any such Person) confirm such notice
in writing no later than one Business Day following the day (i)(A) when the
Commission notifies the Company whether there will be a "review" of such
Registration Statement and whenever the Commission comments in writing on such
Registration Statement (the Company shall provide true and complete copies
thereof and all written responses thereto to Special Counsel); and (B) with
respect to the Registration Statement or any post-effective amendment, when the
same has become effective; (ii) of any request by the Commission or any other
Federal or state governmental authority for amendments or supplements to the
Registration Statement or Prospectus or for additional information; (iii) of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement covering any or all of the Registrable Securities or the
initiation of any Proceedings for that purpose; (iv) if at any time any of the
representations and warranties of the Company contained in the Transaction
Documents ceases to be true and correct in all material respects; (v) of the
receipt by the Company of any notification with respect to the suspension of the
qualification or exemption from qualification of any of the Registrable
Securities for sale in any jurisdiction, or the initiation or threatening of any
Proceeding for such purpose; and (vi) of the occurrence of any event or passage
of time that makes the financial statements included in the Registration
Statement ineligible for inclusion therein or any statement made in the
Registration Statement or Prospectus or any document incorporated or deemed to
be incorporated therein by reference untrue in any material respect or that
requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

         (e)   Use its best efforts to avoid the issuance of, or, if issued,
obtain the withdrawal of (i) any order suspending the effectiveness of each
Registration Statement, or (ii) any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in
any jurisdiction, at the earliest practicable moment.

         (f)   Furnish to each Holder and their Special Counsel, without charge,
at least one conformed copy of each Registration Statement and each amendment
thereto, including financial statements and schedules, all documents
incorporated or deemed to be incorporated therein by reference, and all exhibits
to the extent requested by such Person

                                       6

<PAGE>   122

(including those previously furnished or incorporated by reference) promptly
after the filing of such documents with the Commission.

         (g)   Promptly deliver to each Holder and their Special Counsel,
without charge, as many copies of the Prospectus or Prospectuses (including each
form of prospectus) and each amendment or supplement thereto as such Persons may
reasonably request. The Company hereby consents to the use of such Prospectus
and each amendment or supplement thereto by each of the selling Holders in
connection with the offering and sale of the Registrable Securities covered by
such Prospectus and any amendment or supplement thereto.

         (h)   Prior to any public offering of Registrable Securities, use its
best efforts to register or qualify or cooperate with the selling Holders and
their Special Counsel in connection with the registration or qualification (or
exemption from such registration or qualification) of such Registrable
Securities for offer and sale under the securities or Blue Sky laws of such
jurisdictions within the United States as any Holder requests in writing, to
keep each such registration or qualification (or exemption therefrom) effective
during the Effectiveness Period and to do any and all other acts or things
necessary or advisable to enable the disposition in such jurisdictions of the
Registrable Securities covered by a Registration Statement; provided that the
Company shall not be required to qualify generally to do business in any
jurisdiction where it is not then so qualified or subject the Company to any
material tax in any such jurisdiction where it is not then so subject.

         (i)   Cooperate with the Holders to facilitate the timely preparation
and delivery of certificates representing Registrable Securities to be delivered
to a transferee pursuant to a Registration Statement, which certificates shall
be free, to the extent permitted by the Purchase Agreement, of all restrictive
legends, and to enable such Registrable Securities to be in such denominations
and registered in such names as any such Holders may request.

         (j)   Upon the occurrence of any event contemplated by Section 3(d)
(vi), as promptly as reasonably possible, prepare a supplement or amendment,
including a post-effective amendment, to a Registration Statement or a
supplement to the related Prospectus or any document incorporated or deemed to
be incorporated therein by reference, and file any other required document so
that, as thereafter delivered, neither such Registration Statement nor such
Prospectus will contain an untrue statement of a material fact or omit to state
a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading.

         (k)   Comply with all applicable rules and regulations of the
Commission in connection with its obligations hereunder.

         (l)   The Company may require each selling Holder to complete a selling
shareholder questionnaire in reasonable and customary form furnishing to the
Company a certified statement as to the number of shares of Common Stock
beneficially owned by such Holder and such other information reasonably
necessary for the preparation of the Registration Statement and, if requested by
the Commission, the controlling person of such Holder.

                                       7

    4.   Registration Expenses. All fees and expenses (other than commissions or
underwriter fees incurred by the Holder to sell its Registrable Securities)
incident to the performance of or compliance with this Agreement by the Company
shall be borne by the Company whether or not any Registrable Securities are sold
pursuant to the Registration Statement. The fees and expenses referred to in the
foregoing sentence shall include, without limitation, (i) all registration and
filing fees (including, without limitation, fees and expenses (A) with respect
to filings required to be made with the NASDAQ and any Subsequent Market on
which the Common Stock is then listed for trading, and (B) in compliance with
state securities or Blue Sky laws, (ii) printing expenses (including, without
limitation, expenses of printing certificates for Registrable Securities), (iii)
reasonable messenger, telephone and delivery expenses, (iv) reasonable fees and
disbursements of counsel for the Company and Special Counsel for the Holders,
(v) Securities Act liability insurance, if the Company so desires such
insurance, and (vi) fees and expenses of all other Persons retained by the
Company in connection with the consummation of the transactions contemplated by
this Agreement. In addition, the Company shall be responsible for all of its
internal expenses incurred in connection with the consummation of the
transactions contemplated by this Agreement (including, without limitation, all
salaries and expenses of its officers and employees performing legal or
accounting duties), the expense of any annual audit and the fees and expenses
incurred in connection with the listing of the Registrable Securities on any
securities exchange as required hereunder.

    5.   Indemnification

         (a)   Indemnification by the Company. The Company shall,
notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, the officers, directors, agents, brokers (including brokers who
offer and sell Registrable Securities as principal as a result of a pledge or
any failure to perform under a margin call of Common Stock), investment advisors
and employees of each of them, each Person who controls any such Holder (within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act) and the officers, directors, agents and employees of each such controlling
Person, to the fullest extent permitted by applicable law, from and against any
and all losses, claims, damages, liabilities, costs (including, without
limitation, costs of preparation and attorneys' fees) and expenses
(collectively, "Losses"), as incurred, arising out of or relating to any untrue
or alleged untrue statement of a material fact contained in any Registration
Statement, any Prospectus or any form of prospectus or in any amendment or
supplement thereto or in any preliminary prospectus, or arising out of or
relating to any omission or alleged omission of a material fact required to be
stated therein or necessary to make the statements therein (in the case of any
Prospectus or form of prospectus or supplement thereto, in light of the
circumstances under which they were made) not misleading, except to the extent,
but only to the extent, that (1) such untrue statements or omissions are based
solely upon information regarding such Holder furnished in writing to the
Company by such Holder expressly for use therein, or to the extent that such
information relates to such Holder or such Holder's proposed method of
distribution of Registrable Securities and was reviewed and expressly approved
in writing by such Holder expressly for use in such Registration Statement, such
Prospectus or such form of Prospectus or in any amendment or supplement thereto
or (2) in the case of an

                                       8

<PAGE>   124

occurrence of an event of the type specified in Section 3(d)(ii)-(vi), the use
by such Holder of an outdated or defective Prospectus after the Company has
notified such Holder in writing that the Prospectus is outdated or defective and
prior to the receipt by such Holder of the Advice contemplated in Section 6(e).
The Company shall notify the Holders promptly of the institution, threat or
assertion of any Proceeding of which the Company is aware in connection with the
transactions contemplated by this Agreement.

         (b)   Indemnification by Holders. Each Holder shall, severally and not
jointly, indemnify and hold harmless the Company, its directors, officers,
agents and employees, each Person who controls the Company (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents or employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses (as
determined by a court of competent jurisdiction in a final judgment not subject
to appeal or review) arising solely out of or based solely upon any untrue
statement of a material fact contained in such Registration Statement, any
Prospectus, or any form of prospectus, or in any amendment or supplement
thereto, or arising solely out of or based solely upon any omission of a
material fact required to be stated therein or necessary to make the statements
therein not misleading to the extent, but only to the extent, that such untrue
statement or omission is contained in any information so furnished in writing by
such Holder to the Company specifically for inclusion in such Registration
Statement or such Prospectus or to the extent that such information relates to
such Holder or such Holder's proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by such Holder
expressly for use in such Registration Statement, such Prospectus or such form
of Prospectus, or in any amendment or supplement thereto. In no event shall the
liability of any selling Holder hereunder be greater in amount than the dollar
amount of the net proceeds received by such Holder upon the sale of the
Registrable Securities giving rise to such indemnification obligation.

         (c)   Conduct of Indemnification Proceedings. If any Proceeding shall
be brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party shall promptly notify the Person
from whom indemnity is sought (the "Indemnifying Party") in writing, and the
Indemnifying Party shall assume the defense thereof, including the employment of
counsel reasonably satisfactory to the Indemnified Party and the payment of all
fees and expenses incurred in connection with defense thereof; provided that the
failure of any Indemnified Party to give such notice shall not relieve the
Indemnifying Party of its obligations or liabilities pursuant to this Agreement,
except (and only) to the extent that it shall be finally determined by a court
of competent jurisdiction (which determination is not subject to appeal or
further review) that such failure shall have proximately and materially
adversely prejudiced the Indemnifying Party.

         (d)   Separate Counsel. An Indemnified Party shall have the right to
employ separate counsel in any such Proceeding and to participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed
in writing to pay such fees and expenses; or (2) the Indemnifying Party shall
have failed promptly to assume the defense of such Proceeding

                                       9

<PAGE>   125

and to employ counsel reasonably satisfactory to such Indemnified Party in any
such Proceeding; or (3) the named parties to any such Proceeding (including any
impleaded parties) include both such Indemnified Party and the Indemnifying
Party, and such Indemnified Party shall have been advised by written opinion of
counsel that a conflict of interest is likely to exist if the same counsel were
to represent such Indemnified Party and the Indemnifying Party (in which case,
if such Indemnified Party notifies the Indemnifying Party in writing that it
elects to employ separate counsel at the expense of the Indemnifying Party, the
Indemnifying Party shall not have the right to assume the defense thereof and
such counsel, who shall represent all other Indemnified Parties who are
similarly situated and who can be represented without conflict by such counsel,
shall be at the expense of the Indemnifying Party). The Indemnifying Party shall
not be liable for any settlement of any such Proceeding effected without its
written consent, which consent shall not be unreasonably withheld. No
Indemnifying Party shall, without the prior written consent of the Indemnified
Party, effect any settlement of any pending Proceeding in respect of which any
Indemnified Party is a party, unless such settlement includes an unconditional
release of such Indemnified Party from all liability on claims that are the
subject matter of such Proceeding.

         (e)   Fees and Expenses of Indemnified Party. All fees and expenses of
the Indemnified Party (including reasonable fees and expenses to the extent
incurred in connection with investigating or preparing to defend such Proceeding
in a manner not inconsistent with this Section) shall be paid to the Indemnified
Party, as incurred, within ten Business Days of written notice thereof to the
Indemnifying Party (regardless of whether it is ultimately determined that an
Indemnified Party is not entitled to indemnification hereunder; provided that
the Indemnifying Party may require such Indemnified Party to undertake to
reimburse all such fees and expenses to the extent it is finally judicially
determined that such Indemnified Party is not entitled to indemnification
hereunder).

         (f)   Contribution. If a claim for indemnification under Section 5(a)
or 5(b) is unavailable to an Indemnified Party (by reason of public policy or
otherwise), then each Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such Losses, in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party and
Indemnified Party in connection with the actions, statements or omissions that
resulted in such Losses as well as any other relevant equitable considerations.
The relative fault of such Indemnifying Party and Indemnified Party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission of a material fact, has been taken or made by, or relates to
information supplied by, such Indemnifying Party or Indemnified Party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such action, statement or omission. The amount paid or
payable by a party as a result of any Losses shall be deemed to include, subject
to the limitations set forth in Section 5(c), any reasonable attorneys' or other
reasonable fees or expenses incurred by such party in connection with any
Proceeding to the extent such party would have been indemnified for such fees or
expenses if the indemnification provided for in this Section was available to
such party in accordance with its terms. The parties hereto agree that it would
not be just and equitable if contribution

                                       10

<PAGE>   126

pursuant to this Section 5(f) were determined by pro rata allocation or by any
other method of allocation that does not take into account the equitable
considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 5(f), no Holder shall be required
to contribute, in the aggregate, any amount in excess of the amount by which the
proceeds actually received by such Holder from the sale of the Registrable
Securities subject to the Proceeding exceeds the amount of any damages that such
Holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission. No Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any Person who was not guilty of such
fraudulent misrepresentation.

         (g)   Non-Exclusive Remedy. The indemnity and contribution agreements
contained in this Section are in addition to any liability that the Indemnifying
Parties may have to the Indemnified Parties.

    6.   Miscellaneous

         (a)   Remedies. In the event of a breach by the Company or by a Holder,
of any of their obligations under this Agreement, each Holder or the Company, as
the case may be, in addition to being entitled to exercise all rights granted by
law and under this Agreement, including recovery of damages, will be entitled to
specific performance of its rights under this Agreement. The Company and each
Holder agree that monetary damages would not provide adequate compensation for
any losses incurred by reason of a breach by it of any of the provisions of this
Agreement and hereby further agrees that, in the event of any action for
specific performance in respect of such breach, it shall waive the defense that
a remedy at law would be adequate.

         (b)   No Inconsistent Agreements. Neither the Company nor any of its
subsidiaries has entered, as of the date hereof, nor shall the Company or any of
its subsidiaries, on or after the date of this Agreement, enter into any
agreement with respect to its securities that is inconsistent with the rights
granted to the Holders in this Agreement or otherwise conflicts with the
provisions hereof. Except as and to the extent specified in Schedule 6(b)
hereto, neither the Company nor any of its subsidiaries has previously entered
into any agreement granting any registration rights with respect to any of its
securities to any Person.

         (c)   No Piggyback on Registrations. Except as and to the extent
specified in Schedule 6(b) hereto, neither the Company nor any of its security
holders (other than the Holders in such capacity pursuant hereto) may include
securities of the Company in the Registration Statement other than the
Registrable Securities, and the Company shall not after the date hereof enter
into any agreement providing any such right to any of its security holders.

         (d)   Compliance. Each Holder covenants and agrees that it will comply
with the prospectus delivery requirements of the Securities Act as applicable to
it in connection with sales of Registrable Securities pursuant to the
Registration Statement.

                                       11

<PAGE>   127

         (e)   Discontinued Disposition. Each Holder agrees by its acquisition
of such Registrable Securities that, upon receipt of a notice from the Company
of suspension under Section 2(d) or of the occurrence of any event of the kind
described in Sections 3(d)(ii), 3(d)(iii), 3(d)(iv), 3(d)(v) or 3(d)(vi), such
Holder will forthwith discontinue disposition of such Registrable Securities
under the Registration Statement until such Holder's receipt of the copies of
the supplemented Prospectus and/or amended Registration Statement contemplated
by Section 3(j), or until it is advised in writing (the "Advice") by the Company
that the use of the applicable Prospectus may be resumed, and, in either case,
has received copies of any additional or supplemental filings that are
incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement. The Company may provide appropriate stop orders to
enforce the provisions of this paragraph.

         (f)   Piggy-Back Registrations. If at any time during the Effectiveness
Period there is not an effective Registration Statement covering all of the
Registrable Securities and the Company shall determine to prepare and file with
the Commission a registration statement relating to an offering for its own
account or the account of others under the Securities Act of any of its equity
securities, other than on Form S-4 or Form S-8 (each as promulgated under the
Securities Act) or their then equivalents relating to equity securities to be
issued solely in connection with any acquisition of any entity or business or
equity securities issuable in connection with stock option or other employee
benefit plans, then the Company shall send to each Holder written notice of such
determination and, if within fifteen days after receipt of such notice, any such
Holder shall so request in writing, the Company shall include in such
registration statement all or any part of such Registrable Securities such
holder requests to be registered, subject to customary underwriter cutbacks
applicable to all holders of registration rights.

         (g)   Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and the Holders of at least two-thirds of the then outstanding Registrable
Securities. Notwithstanding the foregoing, a waiver or consent to depart from
the provisions hereof with respect to a matter that relates exclusively to the
rights of Holders and that does not directly or indirectly affect the rights of
other Holders may be given by Holders of at least a majority of the Registrable
Securities to which such waiver or consent relates; provided, however, that the
provisions of this sentence may not be amended, modified, or supplemented except
in accordance with the provisions of the immediately preceding sentence.

         (h)   Notices. Any and all notices or other communications or
deliveries required or permitted to be provided hereunder shall be in writing
and shall be deemed given and effective on the earliest of (i) the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified in this Section prior to 6:30 p.m. (New
York City time) on a Business Day, (ii) the Business Day after the date of

         (i)   Successors and Assigns. This Agreement shall inure to the benefit
of and be binding upon the successors and permitted assigns of each of the
parties and shall inure

                                       13

<PAGE>   129

to the benefit of each Holder. The Company may not assign its rights or
obligations hereunder without the prior written consent of each Holder. Each
Holder may assign their respective rights hereunder in the manner and to the
Persons as permitted under the Purchase Agreement.

         (j)   Counterparts. This Agreement may be executed in any number of
counterparts, each of which when so executed shall be deemed to be an original
and, all of which taken together shall constitute one and the same Agreement. In
the event that any signature is delivered by facsimile transmission, such
signature shall create a valid binding obligation of the party executing (or on
whose behalf such signature is executed) the same with the same force and effect
as if such facsimile signature were the original thereof.

         (k)   Governing Law. All questions concerning the construction,
validity, enforcement and interpretation of this Agreement shall be governed by
and construed and enforced in accordance with the internal laws of the State of
New York, without regard to the principles of conflicts of law thereof. Each
party hereby irrevocably submits to the exclusive jurisdiction of the state and
federal courts sitting in the City of New York, borough of Manhattan, for the
adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein, and hereby irrevocably
waives, and agrees not to assert in any suit, action or proceeding, any claim
that it is not personally subject to the jurisdiction of any such court, that
such suit, action or proceeding is improper. Each party hereby irrevocably
waives personal service of process and consents to process being served in any
such suit, action or proceeding by mailing a copy thereof to such party at the
address in effect for notices to it under this Agreement and agrees that such
service shall constitute good and sufficient service of process and notice
thereof. Nothing contained herein shall be deemed to limit in any way any right
to serve process in any manner permitted by law.

         (l)   Cumulative Remedies. The remedies provided herein are cumulative
and not exclusive of any remedies provided by law.

         (m)   Severability. If any term, provision, covenant or restriction of
this Agreement is held by a court of competent jurisdiction to be invalid,
illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their reasonable efforts to find and employ an alternative
means to achieve the same or substantially the same result as that contemplated
by such term, provision, covenant or restriction. It is hereby stipulated and
declared to be the intention of the parties that they would have executed the
remaining terms, provisions, covenants and restrictions without including any of
such that may be hereafter declared invalid, illegal, void or unenforceable.

         (n)   Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

         (o)   Shares Held by the Company and its Affiliates. Whenever the
consent or approval of Holders of a specified percentage of Registrable
Securities is required hereunder, Registrable Securities held by the Company or
its Affiliates (other than any Holder or

                                       14

<PAGE>   130

transferees or successors or assigns thereof if such Holder is deemed to be an
Affiliate solely by reason of its holdings of such Registrable Securities) shall

                                     Annex A
                              PLAN OF DISTRIBUTION

    The Selling Stockholders and any of their pledgees, assignees and
successors-in-interest may, from time to time, sell any or all of their shares
of Common Stock on any stock exchange, market or trading facility on which the
shares are traded or in private transactions. These sales may be at fixed or
negotiated prices. The Selling Stockholders may use any one or more of the
following methods when selling shares:

    -    ordinary brokerage transactions and transactions in which the
         broker-dealer solicits purchasers;

    -    block trades in which the broker-dealer will attempt to sell the shares
         as agent but may position and resell a portion of the block as
         principal to facilitate the transaction;

    -    purchases by a broker-dealer as principal and resale by the
         broker-dealer for its account;

    -    an exchange distribution in accordance with the rules of the applicable
         exchange;

    -    privately negotiated transactions;

    -    short sales;

    -    broker-dealers may agree with the Selling Stockholders to sell a
         specified number of such shares at a stipulated price per share;

    -    a combination of any such methods of sale; and

    -    any other method permitted pursuant to applicable law.

    The Selling Stockholders may also sell shares under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

    The Selling Stockholders may also engage in short sales against the box,
puts and calls and other transactions in securities of the Company or
derivatives of Company securities and may sell or deliver shares in connection
with these trades. The Selling Stockholders may pledge their shares to their
brokers under the margin provisions of customer agreements. If a Selling
Stockholder defaults on a margin loan, the broker may, from time to time, offer
and sell the pledged shares.

    Broker-dealers engaged by the Selling Stockholders may arrange for other
brokers-dealers to participate in sales. Broker-dealers may receive commissions
or discounts from the Selling Stockholders (or, if any broker-dealer acts as
agent for the purchaser of

<PAGE>   135

shares, from the purchaser) in amounts to be negotiated. The Selling
Stockholders do not expect these commissions and discounts to exceed what is
customary in the types of transactions involved.

    The Selling Stockholders and any broker-dealers or agents that are involved
in selling the shares may be deemed to be "underwriters" within the meaning of
the Securities Act in connection with such sales. In such event, any commissions
received by such broker-dealers or agents and any profit on the resale of the
shares purchased by them may be deemed to be underwriting commissions or
discounts under the Securities Act.

    The Company is required to pay all fees and expenses incident to the
registration of the shares, including fees and disbursements of counsel to the
Selling Stockholders. The Company has agreed to indemnify the Selling
Stockholders against certain losses, claims, damages and liabilities, including
liabilities under the Securities Act.

                           TRANSFER AGENT INSTRUCTIONS

                                                                   July 27, 2000

Ladies and Gentlemen:

     Reference is made to that certain Convertible Debenture Purchase Agreement
(the "Purchase Agreement") among Eltrax Systems, Inc., a Minnesota corporation
(the "Company"), and the purchasers named therein (the "Holders") pursuant to
which the Company is issuing to the Holders its 5.00% Convertible Debentures,
due July 26, 2001 (the "Debentures"), and certain Common Stock purchase warrants
(the "Warrants") which shall be convertible and exercisable, respectively, into
shares of the Company's common stock, $.01 par value per share (the "Common
Stock"). The shares of Common Stock issuable upon conversion of the Debentures
and upon exercise of the Warrants are collectively referred to herein as
"Underlying Shares."

     This letter shall serve as our irrevocable authorization and direction to
you (provided that you are the transfer agent for the Company with respect to
the Common Stock at such time) to issue Underlying Shares from time to time upon
notice from the Company to issue such Underlying Shares. So long as you have
previously received (x) an opinion of the Company's outside counsel
substantially in the form of Exhibit I attached hereto (which the Company shall
direct be delivered to you by such outside counsel upon the effectiveness of the
registration statement covering resales of Underlying Shares) stating that a
registration statement covering resales of Underlying Shares has been declared
effective by the Securities and Exchange Commission under the Securities Act of
1933, as amended, and that Underlying Shares may be issued (or reissued if they
have been issued at a time when there was not such an effective registration
statement) or resold without any restrictive legend (the "Opinion") and (y) a
copy of such registration statement, then certificates representing Underlying
Shares shall not bear any legend restricting transfer of Underlying Shares
thereby and should not be subject to any stop-transfer restriction. Provided,
however, that if you have not previously received a copy of the Opinion and such
registration statement, then the certificates representing Underlying Shares
shall bear the following legend:

          THESE SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND
          EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN
          RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT
          OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT
          BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
          STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE
          EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION

<PAGE>   137

          REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE
          STATE SECURITIES LAWS.

and, provided, further, that the Company may, from time to time, notify you to
place stop-transfer restrictions on the certificates for Underlying Shares in
the event, but only in the event, a registration statement covering Underlying
Shares is subject to amendment for events then current.

     Please be advised that the Holders have relied upon this instruction letter
as an inducement to enter into the Purchase Agreement and, accordingly, the
Holders are a third party beneficiary to these instructions.

     Please execute this letter in the space indicated to acknowledge your
agreement to act in accordance with these instructions.

         Re:      Shares of Common Stock of Eltrax Systems, Inc.

Gentlemen:

         1. SUBSCRIPTION. The undersigned ("INVESTOR") hereby tenders this
subscription and applies to purchase 180,000 shares of Common Stock (the
"SHARES") of Eltrax Systems, Inc. (the "COMPANY"), for the aggregate cash
consideration of $990,000, pursuant to the terms of this Subscription Agreement.
The Investor further sets forth statements upon which you may rely to determine
the suitability of the Investor to purchase the Shares.

         2. REPRESENTATIONS AND UNDERSTANDINGS. The Investor hereby makes the
following representations, warranties and agreements and confirms the following
understandings with the Company:

            (i)    The Investor has reviewed the Company's SEC filings
(including but not limited to, its Annual Reports on Form 10-K (as amended on
Form 10-K/A) for the fiscal years ended December 31, 1998 and December 31, 1999,

Technology Partners, Inc., (the "MERGER")), and has received a copy of a draft
Form S-4, with respect to the Merger (the "DRAFT S-4"), (collectively, the
"Company SEC Filings") and has had an opportunity to question representatives of
the Company and obtain such additional information concerning the Company as the
Investor has requested.

            (ii)   The Investor has sufficient experience in financial and
business matters to be capable of utilizing such information to evaluate the
merits and risks of the Investor's investment, and to make an informed decision
relating thereto; or the Investor has utilized the services of a purchaser
representative and together they have sufficient experience in financial and
business matters that they are capable of utilizing such information to evaluate
the merits and risks of the Investor's investment, and to make an informed
decision relating thereto.

            (iii)  The Investor has evaluated the risks of this investment in
the Company, including those risks particularly described in the Draft S-4, and
has determined that the investment is

<PAGE>   2

suitable. The Investor has adequate financial resources for an investment of
this character, and at this time it could bear a complete loss of its
investment. The Investor understands that any projections which may be made in
the Draft S-4 are mere estimates and may not reflect the actual results of the
Company's operations.

            (iv)   The Investor understands that the Shares are not being
registered under the Securities Act of 1933, as amended (the "1933 ACT"), on the
ground that the issuance thereof is exempt under Section 4(2) of the 1933 Act
and Rule 506 of Regulation D promulgated thereunder, and that reliance on such
exemption is predicated in part on the truth and accuracy of the Investor's
representations and warranties. The Investor covenants not to sell, transfer or
otherwise dispose of any of the Shares unless such Shares have been registered
under the 1933 Act, or an exemption from registration is available.

            (v)    The Investor understands that the Shares are not being
registered under the securities laws of certain states on the basis that the
issuance thereof is exempt as an offer and sale not involving a public offering
in such state. The Investor understands that reliance on such exemptions is
predicated in part on the truth and accuracy of the Investor's representations
and warranties. The Investor covenants not to sell, transfer or otherwise
dispose of any of the Shares unless such Shares have been registered under the
applicable state securities laws, or an exemption from registration is
available.

            (vi)   The Investor is an Accredited Investor as defined in Rule 501
of Regulation D promulgated under Section 4(2) of the 1933 Act.

            (vii)  The Investor has no need for any liquidity in its investment
and is able to bear the economic risk of his investment for an indefinite period
of time. The Investor has been advised and is aware that: (a) there is a limited
public market for the Shares; (b) it may not be possible to liquidate the
investment readily; (c) the Investor must bear the economic risk of its
investment in the Shares for an indefinite period of time because the Shares
have not been registered under the 1933 Act and applicable state law; (d) a
legend as to the restrictions on transferability of the Shares will be made on
the Shares, and (e) a notation in the appropriate records of the Company will be
made with respect to any restrictions on transfer of the Shares.

            (viii) The Investor has relied solely upon the Company's SEC
filings, the Draft S-4, the Company's representations and warranties herein and
independent investigations made by him or his purchaser representative with
respect to the Shares subscribed for herein, and no oral or written
representations other than as referred to herein have been made to the Investor
or relied upon by the Investor.

            (ix)   The Investor agrees not to transfer or assign this
subscription or any interest therein.

            (x)    The Investor hereby acknowledges and agrees that, except as
may be specifically provided herein, the Investor is not entitled to withdraw,
terminate or revoke this subscription once it has been duly executed by both
parties listed on the signature page hereto.

                                       2
<PAGE>   3

            (xi)   If the Investor is a partnership, corporation or trust, it
has been duly formed, is validly existing, has full power and authority to make
this investment, and has not been formed for the specific purpose of investing
in the Shares. This Subscription Agreement and all other documents executed in
connection with this subscription for Shares are valid, binding and enforceable
agreements of the Investor.

         3. INDEMNIFICATION. The representations, warranties and agreements of
the parties contained herein are continuing in nature and shall survive the
acceptance of this Subscription Agreement. Each party hereby agrees to indemnify
and hold harmless the other party and all of its affiliates, attorneys,
accountants, employees, officers, directors, members and agents from any
liability, claims, costs, damages, losses or expenses incurred or sustained by

         Agreements and the issuance of the Shares. These Agreements have been

         Cereus Technology Partners, Inc., which has been obtained and such
         declarations, filings, registrations, notices, authorizations, consents
         or approvals which, if not made or obtained, as the case may be, would
         not, in the aggregate, result in a Company Material Adverse Effect.

1997 (the documents referred to in clauses (a), (b) and (c) are collectively
referred to as the "COMPANY SEC REPORTS"). As of their respective dates, the
Company SEC Reports contained no untrue statement of a material fact or omitted
to state a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. The audited financial statements for the fiscal year ended
December 1999 and the two prior fiscal years, and the unaudited consolidated
financial statements of Company included in Company's Quarterly Report on Form
10-Q for the period ended March 31, 2000 (collectively, the "COMPANY FINANCIAL
STATEMENTS"), have been prepared in accordance with GAAP (except as may be
indicated therein or in the notes thereto) and fairly present the financial
position of Company and its Subsidiaries as of the dates thereof and the results
of their operations and changes in financial position for the periods then
ended. Since March 31, 2000, there has not occurred any event, circumstance or
state of facts that would reasonably be expected, individually or in the
aggregate, to have a Material Adverse Effect on the Company.

            (vi)  Litigation. There is no suit, claim, action, proceeding or
investigation pending or, to the knowledge of Company, threatened against
Company or any Subsidiary of Company before any governmental entity that would
reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect, and, to the knowledge of Company, there are no existing
facts or circumstances that would reasonably be expected to result in such a
suit, claim, action, proceeding or investigation. Company is not aware of any
facts or circumstances which would reasonably be expected to result in the
denial of insurance coverage under policies issued to the Company and its
Subsidiaries in respect of such suits, claims, actions, proceedings and
investigations for which Company has a reasonable expectation of obtaining
insurance coverage, except in any case as would not reasonably be expected to
have, individually or in the aggregate, a Company Material Adverse Effect.

            (vii) Intellectual Property. Except as would not reasonably be
expected to have, individually or in the aggregate, a Company Material Adverse
Effect, (i) Company and its Subsidiaries own or possess adequate licenses or
other valid rights to use all patents, patent applications, patent rights,
trademarks, trademark rights, trade names, trade dress, trade name rights,
copyrights and copyright registrations and applications, copyright rights,
service marks, trade secrets, applications for trademarks and for service marks,
know- how and other proprietary rights and information used or held for use in
connection with the respective businesses of Company and its Subsidiaries as
currently conducted (collectively, the "COMPANY IP"), free and clear of all
liens other than those in favor of PNC Bank, National Association ("PNC"), and
(ii) Company is unaware of any assertion or claim challenging the ownership, use
or validity of any of the foregoing. The licenses associated with the Company IP
are valid and binding obligations of Company, enforceable in accordance with
their terms, and there are no material breaches or defaults thereunder. The
conduct of the respective businesses of Company and its Subsidiaries as
currently conducted does not infringe upon any patent, patent right, license,
trademark, trademark right, trade dress, trade name, trade name right, service
mark, copyright or copyright right of any third party that would reasonably be
expected to have, individually or in the aggregate, a Company Material Adverse
Effect. To the knowledge of Company, there are no infringements of any
proprietary rights owned by or licensed by or to the Company or any Subsidiary
of the Company that could reasonably be expected to have, individually or in the
aggregate, a Company Material Adverse Effect.
