ITEM 2.        ACQUISITION OR DISPOSITION OF ASSETS.
 

MERGER WITH ENCORE SYSTEMS, INC. AND ACQUISITION OF GLOBAL SYSTEMS AND 
SUPPORT, INC. AND FIVE STAR SYSTEMS, INC.

     On September 10, 1998, pursuant to an Acquisition Agreement dated as of 
August 31, 1998 (the "Acquisition Agreement") by and among Eltrax Systems, 
Inc., a Minnesota corporation (the "Company"), Encore Acquiring Corp., a 
Georgia corporation ("Acquiring Sub"), Global Systems and Support, Inc., a 
Georgia corporation ("GSS"), Five Star Systems, Inc., a Georgia corporation 
("Five Star"), Penelope Sellers ("Sellers"), and Joseph T. Dyer ("Dyer"; 
Sellers and Dyer are sometimes hereinafter collectively referred to as the 
"Shareholders"), Acquiring Sub merged with and into Encore, and the Company 
acquired all of the outstanding stock of GSS and Five Star.  As a result of 
the merger, the separate existence of Acquiring Sub ceased and Encore 
continues as the surviving corporation and a wholly owned subsidiary of the 
Company.  Encore, GSS, and Five Star are providers of proprietary software 
products and technology services to the hospitality industry.  The 
description of the merger and stock acquisitions included herein does not 
purport to be complete and is qualified in its entirety by reference to the 
Acquisition Agreement which is filed as Exhibit 2.1 hereto.

     Pursuant to the terms of the Acquisition Agreement, upon the closing of 
the merger on September 10, 1998, 465,000 shares of common stock, $.01 par 
value per share, of the Company (the "Common Stock") were issued to the 
Shareholders in connection with the merger, and the Company paid the 
Shareholders $8.5 million for all of the outstanding capital stock of GSS and 
Five Star.  Furthermore, in the event the Company elects to treat the 
acquisition of Five Star stock as a "deemed sale of assets" pursuant to 
Section 338(h)(10) of the Internal Revenue Code, the Company will reimburse 
the Shareholders (on a "grossed-up" basis for taxes) for the additional tax 
resulting from such election.  The 465,000 shares of Common Stock issued in 
connection with the merger represents approximately 3.6% of the issued and 
outstanding shares of Common Stock after the closing. All of the shares of 
the Common Stock that have been issued to the Shareholders in connection with 
the merger are "restricted stock", as defined in Rule 144 promulgated under 
the Securities Act of 1933, and have certain demand and "piggyback" 
registration rights.

     In addition to the foregoing, the Company entered into an Employment and 
Non-Competition Agreement with Penelope Sellers that provides for the 
employment by the Company of Sellers for a period of one (1) year from 
September 1, 1998. The agreement also provides for a non-compete period 
through two (2) years after the term of the agreement.  The description of 
the Employment and Non-Competition Agreement included herein does not purport 
to be complete and is qualified in its entirety by reference to the 
Employment and Non-Competition Agreement which is filed as Exhibit 10.1 
hereto.

     For accounting purposes, it is intended that the merger will be treated 
as a purchase transaction under APB Opinion No. 16.

ITEM 5.        OTHER EVENTS.

CREDIT AGREEMENT

     The Company has entered into a new three-year credit agreement (the 
"Credit Agreement") with State Street Bank and Trust Company that provides 
for a $4.0 million three-year term loan and a $6.0 million revolving credit 
loan.  Each loan is due on September 10, 2001, and is secured by a security 
interest in all of the Company's personal property.  In addition to monthly 
interest payments under each loan, equal monthly principal payments of 
$111,111 are


                                      -2-

<PAGE>

required pursuant to the term loan.  The revolving credit loan accrues 
interest at a rate 100 basis points above the "prime rate" and the term loan 
accrues interest at a rate equal to a rate (i) 150 basis points above the 
"prime rate" or (ii) 425 basis points above the LIBOR rate, as selected by 
the Company pursuant to the terms of the Credit Agreement.  The description 
of the Credit Agreement included herein does not purport to be complete and 
is qualified in its entirety by reference to the Credit Agreement which is 
filed as Exhibit 10.2 hereto.

                           REPRESENTATIONS AND WARRANTIES
                       OF THE COMPANIES AND THE SHAREHOLDERS


                                       5

<PAGE>



     Each of the Companies (to the extent applicable to itself and its 
business) and each of the Shareholders, jointly and severally (except as 
noted at Section 2.19), represent and warrant to Eltrax and to Acquiring Sub, 
that the following statements are true, complete and correct as of the 
Closing Date:

2.1. CORPORATE ORGANIZATION.

     Each of Encore, GSS and Five Star is a corporation duly organized, 
validly existing and in good standing under the laws of Georgia, has full 
corporate power and authority to carry on its respective business as it is 
now being conducted and to own, lease and operate its respective properties 
and assets. Each of the Companies has heretofore delivered to Eltrax complete 
and correct copies of its certified articles of incorporation and bylaws, as 
presently in effect.  In addition, each of the Companies has delivered to 
Eltrax a good standing certificate from the State of Georgia bearing a date 
within thirty (30) days of the Closing Date.  Except as set forth on Schedule 
2.1, each of the Companies is duly qualified or licensed to do business as a 
foreign corporation and is in good standing in every jurisdiction in which 
the character or location of the properties and assets owned, leased or 
operated by it or the nature of the business conducted by it requires such 
qualification or licensing, except where the failure to be so qualified, 
licensed or in good standing in such other jurisdiction could not, 
individually or in the aggregate, reasonably be expected to have a material 
adverse effect on its business taken as a whole.  Except for 40 shares of 
Common Stock of On Command, Inc. held by Encore, none of the Companies owns 
or controls any interest in any corporation, partnership, joint venture or 
other business association or entity.

2.2. CAPITALIZATION AND TITLE TO SHARES.

     The authorized capital stock of Encore consists of 20,000,000 shares of 
Class A common stock, no par value, and 20,000,000 shares of Class B common 
stock, no par value.  At Closing 767,777 shares of Class A common stock will 
be issued and outstanding and no shares of Class B common stock will be 
outstanding.  The authorized capital stock of GSS consists of 100,000 shares 
of common stock, no par value, of which 1,000 shares will be issued and 
outstanding at Closing.  The authorized capital stock of Five Star consists 
of 100,000 shares of common stock, no par value, of which 1,000 shares will 
be issued and outstanding at Closing.  All issued and outstanding shares of 
capital stock of each of the Companies are (or will be) duly authorized, 
validly issued, fully paid and nonassessable and have not been issued in 
violation of, any preemptive rights.  There are no outstanding options, 
warrants, conversion privileges or other rights to purchase or acquire any 
shares of capital stock of any of the Companies or any outstanding securities 
that are convertible into or exchangeable for such stock.  Except as 
disclosed on Schedule 2.2, there are no contracts, commitments, 
understandings, arrangements or restrictions by which any of the Companies 
are bound to issue any additional shares of their capital stock or any 
options, warrants, conversion privileges or other rights to purchase or 
acquire any capital stock of any of the Companies or any securities 
convertible into or exchangeable for such stock.  The Shareholders 
collectively own beneficially and of record all of the issued and outstanding 
capital stock of the Companies.

2.3. AUTHORIZATION.

     The Board of Directors of each of the Companies have taken all action
required by law, their respective articles of incorporation, bylaws and
otherwise to authorize the execution, delivery and performance of this Agreement
and the consummation of the transactions described in this Agreement (the
"Transactions").  No other consent or approval from any party is necessary to
validly complete the Transactions, other than as may be required under the GBCC.
This Agreement has been duly and validly executed and delivered by the
Companies, and is the valid and binding legal obligation of each of the


                                       6

<PAGE>



Companies, enforceable against each of them in accordance with its terms, 
subject to the affect of applicable bankruptcy, reorganization, insolvency, 
moratorium, fraudulent conveyance and other laws affecting the rights of 
creditors generally (the "Enforceability Exceptions"), or the availability of 
specific performance, injunctive relief and other equitable remedies and to 
general principles of equity (regardless of whether such principles are 
considered in a proceeding in equity or at law).

2.4. NON-CONTRAVENTION.

     In addition to the foregoing representations, each Shareholder severally,
and not jointly, represents and warrants to Eltrax that as to such Shareholder,
the following statements are true, complete and correct as of the Closing Date:

          (a)  Such Shareholder is the record and beneficial owner of the shares
     of Encore, GSS and Five Star set forth opposite each Shareholder's name on

     to convey such shares in accordance with the terms of this Agreement.

          (b)  Such Shareholder has all requisite legal power to enter into this

     performance of this Agreement and the Transactions.

     by such Shareholder, and is the valid and binding legal obligation of the
     Shareholders enforceable against each of them in accordance with its terms,

     performance, injunctive relief and other equitable remedies and to general

     in a proceeding in equity or at law).

     pursuant to the Merger for such Shareholder's sole account (and such
     Shareholder will be the sole beneficial owners thereof) for the purpose of
     investment and not with a view to distribution thereof within the meaning
     of the Securities Act of 1933, as amended and the rules and regulations

     distribution or selling such shares of Eltrax Common Stock in connection
     with any such distribution, and such Shareholder understands that such
     shares have not been registered under the Securities Act or any applicable
     state securities law and therefore cannot be resold unless they are
     registered under the Securities Act and any applicable state securities
     laws or unless an exemption from registration is available.

          (e)  There are available over the Internet various public filings made

                    REPRESENTATIONS AND WARRANTIES OF ELTRAX

     Eltrax represents and warrants to the Shareholders that the following
statements are true, complete and correct as of the Closing Date:

     3.1. ORGANIZATION.

     Each of Eltrax and Acquiring Sub is a corporation duly organized, validly
existing and in good standing under the laws of the state of its incorporation
and each has all requisite corporate power and authority to own, lease and
operate its respective properties and to carry on its business as it is now
being conducted.  Acquiring Sub is a recently-formed Georgia corporation that
has not conducted, and will not conduct prior to the Closing, any activities
other than those incident to its formation and in connection with the
consummation of the Encore Merger.  Each of Eltrax and Acquiring Sub is duly
qualified and in good standing to do business in each jurisdiction in which the
property owned, leased or operated by it or the nature of the business conducted
by it makes such qualification necessary and where the failure to qualify would
have a material adverse effect on the business, results of operations or
financial condition of Eltrax and its subsidiaries taken as a whole.

     3.2. AUTHORITY AND VALIDITY OF AGREEMENT.

     The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly and validly authorized and
approved by the Boards of Directors of Eltrax and Acquiring Sub and by Eltrax as
the sole shareholder of Acquiring Sub, and no other corporate proceedings on the
part of Eltrax or Acquiring Sub are necessary to authorize this Agreement or to
consummate the transactions contemplated hereby.  This Agreement and each
Transaction document to which each is a party has been duly and validly executed
by each of Eltrax and Acquiring Sub and constitutes valid and binding
obligations of Eltrax and Acquiring Sub, enforceable against each of them in
accordance with their terms, subject to the Enforceability Exceptions.

     3.3. CONSENTS AND APPROVALS.

     The execution and delivery of this Agreement and the consummation of the
Transactions will not, except for any applicable requirements of the Securities
Act and state securities laws, and the filing and recordation of the appropriate
merger document as required by the GBCC, require any filing with or permit,
consent or approval of any party or authority.


                                      16
<PAGE>

     3.4. CAPITALIZATION.

     The authorized capital stock of Eltrax consists of 50,000,000 shares of
Eltrax Common Stock and 970,000 shares of undesignated preferred stock, of which
there were 12,573,438 shares of Eltrax Common Stock issued and outstanding on
August 7, 1998.  All shares of Eltrax Common Stock to be issued and delivered in
the Encore Merger will be, at the time of issuance and delivery, validly issued,
fully paid, nonassessable and free of preemptive rights.  Eltrax holds no shares
of Eltrax Common Stock in its treasury.  As of August 7, 1998, there were
outstanding stock options to purchase an aggregate of 2,010,441 shares of Eltrax
Common Stock.

     3.5. NON-CONTRAVENTION.

     Neither the execution, delivery and performance of this Agreement nor the
consummation of the transactions contemplated herein will:  (i) violate or be in
conflict with any provision of the articles of incorporation or bylaws of Eltrax
or Acquiring Sub; or (ii) be in conflict with, or constitute a default under,
any instrument or other agreement or obligation to which Eltrax or Acquiring Sub
is a party.

     3.6. BROKERS.

     Neither Eltrax, Acquiring Sub nor any of  their respective directors,
officers or employees has employed any broker, finder, or financial advisor or
incurred any liability for any brokerage fee or commission, finder's fee or
financial advisory fee, in connection with the Transactions, nor is there any
basis known to either Eltrax or Acquiring Sub for any such fee or commission to
be claimed by any person or entity.

     3.7. SCOPE OF DUE DILIGENCE REVIEW.

     Eltrax and its representatives have had access to, and have had sufficient
time to review and consider, the books and records of the Companies, including,
without limitation, the Griffin Records (defined below).  Eltrax has been
afforded an opportunity to ask questions of and receive answers from the
Shareholders and the employees, customers and representatives of the Companies
concerning the business and financial condition of the Companies, and to obtain
any additional information as Eltrax has requested to satisfy Eltrax's due
diligence needs.  The term Griffin Records means the items disclosed on Schedule
3.7.

     3.8  SEC REPORTS AND FINANCIAL STATEMENTS.

     Since December 31, 1995, Eltrax has filed all Eltrax SEC Reports required
to be filed by Eltrax with the SEC.  As of their respective dates, the Eltrax
SEC Reports complied in all material respects with the applicable requirements
of the Securities Act, the Exchange Act and the rules and regulations
promulgated thereunder applicable to such Eltrax SEC Reports and, except to the
extent that information contained in any Eltrax SEC Report has been revised or
superseded by a later Eltrax SEC Report filed and publicly available prior to
the date of this Agreement (a "Filed SEC Document"), none of the Eltrax SEC
Reports contained any untrue statement of a material fact or omitted to state
any material fact required to be stated therein or necessary in order to make
the statements therein, in light of the circumstances under which they were
made, not misleading.  The financial statements of Eltrax included in the Eltrax
SEC Reports or Filed SEC Documents complied as to form in all material respects
with applicable accounting requirements and the published rules and regulations
of the SEC with respect thereto, were prepared in accordance with generally
accepted accounting principles (except, in the case of


                                      17
<PAGE>

unaudited statements, as permitted by the SEC) applied on a consistent basis 
during the periods involved (except as may be indicated in the notes thereto) 
and presented fairly in all material respects the consolidated financial 
position of Eltrax and its consolidated subsidiaries as of the dates thereof 
and the consolidated results of their operations and cash flows for the periods 
then ended (subject, in the case of unaudited statements, to normal year-end 
audit adjustments).  Except as set forth in the Eltrax SEC Reports or Filed SEC 
Documents, neither Eltrax nor any of the Eltrax Subsidiaries has any 
liabilities or obligations of any nature (whether accrued, absolute, contingent 
or otherwise) required by generally accepted accounting principles to be set 
forth on a consolidated balance sheet of Eltrax and its consolidated 
subsidiaries or in the notes.  No subsidiary of Eltrax is required to file any 
forms, reports or other documents with the SEC pursuant to Sections 12 or 15 of 
the Exchange Act.  Since the date of last Filed SEC Document, Eltrax has not 
made or suffered any change in its condition (financial or otherwise), or 
experienced any event or failed to take any action which could reasonably be 
expected to have a material adverse effect on the business of Eltrax.

     3.9. INVESTIGATIONS; LITIGATION.

     Except as described in the Eltrax SEC Reports, there are no claims or
actions by anyone against or directly involving Eltrax or its subsidiaries that
are pending or, to the knowledge of Eltrax, have been threatened.  To the
knowledge of Eltrax, there is no basis for any such claim or action.

     3.10.      ACCURACY OF INFORMATION.

     To the knowledge of Eltrax, no representation or warranty by Eltrax in this
Agreement contains any untrue statement of material fact or omits to state any
material fact necessary in order to make the statements herein, in light of the
circumstances under which they were made, not misleading.

     4.1. CONFIDENTIALITY.

     The parties hereto will not use, or permit the use of, any of the
information relating to any other party hereto furnished to it in connection
with the Transactions ("Information") in a manner or for a purpose detrimental
to such other party or otherwise than in connection with the Transaction, and

or entity, other than their responsible directors, officers, employees,
investment advisors, accountants, counsel and other authorized representatives
and agents, except as may be required by judicial or administrative process or,
in the opinion of such party's regular counsel, by other requirements of law,
unless the disclosing party first obtains the prior written consent of the other
parties hereto. The parties hereto also will promptly return to the party from

This Section 4.1 survives the Closing and any termination of this Agreement.

<PAGE>

         4.2. FURTHER ASSURANCES; COOPERATION.

     Each party hereto will, at and after Closing, execute and deliver such
instruments and take such other actions as the other party or parties, as the
case may be, may reasonably require in order to carry out the intent of this
Agreement, including, but not limited to, any securities filings and any
assignments necessary to transfer all rights to the Intellectual Property to the
Companies.

     4.3. REGISTRATION RIGHTS AND LOCK-UP.

          (A)  Eltrax agrees to provide the Shareholders with the registration
     rights with respect to Eltrax Common Stock as set forth on Exhibit C
     hereto.

          (b)  With respect to three hundred ninety thousand (390,000) shares of
     the Eltrax Common Stock to be issued to the Shareholders in connection with
     the Encore Merger, each of the Shareholders agrees not to, directly or
     indirectly, offer, sell, contract to sell or otherwise dispose of (or
     announce any offer, sale, contract of sale or other disposition) any shares
     of such Eltrax Common Stock until August 31, 2000; provided, however, that
     this Section 4.3(b) shall not apply to any transfer by a Shareholder to:
     (i) any other Shareholder; (ii) any family member (within the meaning of
     Code Section 267(c)(4)) of a transferring Shareholder; and (iii) any sale
     pursuant to registration rights of the Shareholders described in paragraph
     (ii) of Exhibit C.

4.4  RECONCILIATION OF GAP INCOME.

          (A) As soon as practicable following the preparation of the final S
     Corporation returns for each of GSS and Five Star, which shall be jointly
     undertaken and reviewed by the Shareholders and Eltrax, but prior the
     filing of such returns, the accountants for Eltrax shall make a
     determination of the actual Gap Income (the "Final Gap Income") based upon
     and consistent with the final S corporation returns.  Eltrax shall deliver
     a copy of such determination (and all supporting data) to the Shareholders
     (the "Notice") who shall have fifteen business (15) days from the date of
     the Notice to dispute such determination by sending a written response to
     Eltrax (the "Response") detailing the differences in the calculation.   In
     the event the Shareholders fail to respond timely or with particularity to
     the Notice, the determination of the Final Gap Income by the Eltrax
     accountants shall be deemed final.  In the event the Response is timely
     delivered and appropriately completed, then the Eltrax accountants and the
     Shareholders (or their advisors) shall have thirty (30) days (the
     "Reconciliation Period") from the date of the Response in which to agree to
     the Final Gap Income.  In the event an agreement cannot be reached, unless
     the parties mutually agree to extend the Reconciliation Period, the
     determination of the Final Gap Income shall be made in accordance with the
     provisions of Section 9.12.

          (B) If the Final Gap Income as ultimately determined in accordance 
     with Section 4.4(a) (subject to any future adjustment by any tax authority)
     is positive (the "Taxable Gap Income"), then: (i) to the extent the Taxable
     Gap Income multiplied by forty-five percent (45%) is more than the Tax
     Distribution, Eltrax will immediately pay the difference to the 
     Shareholders, 90% to Penelope Sellers and 10% to Joseph T. Dyer, and (ii)
     to the extent the Taxable Gap Income multiplied by forty-five percent (45%)
     is less than the Tax Distribution, the Shareholders will immediately remit
     the difference to Eltrax, 90% to be paid by Penelope Sellers and 10% by
     Joseph T. Dyer.

     4.5  ADJUSTMENT FOR POST-MAY 31, 1998 ADVANCES AND DISTRIBUTIONS.

     As soon as practicable following the Closing, a determination shall be made
by the accountants for Eltrax as to the total of all advances, loans,
distributions or other extensions of credit made by the Companies to any of the
Shareholders, for the period June 1, 1998 through Closing, which remain unpaid
as of the Closing Date (collectively, the "Advances"), exclusive of the Tax
Distribution described in Section 2.9, a distribution of approximately $188,888
made to the Shareholders in June of 1998 and a $35,000 payment to the
Shareholders made in January of 1998.  The notice procedures detailed in Section
4.4 shall be utilized with respect to the determination of the Advances.  To the
extent such Advances exceed the amounts reflected in the Companies' balance
sheet dated May 31, 1998 (a copy of which is attached hereto as Exhibit E) as
receivables from Shareholders or receivables from a Related Party (the "Excess
Advance"), the Shareholders shall immediately pay Eltrax an amount equal to the
Excess Advance, in proportion to the share of the Excess Advance which they
possess.

     4.6  CODE SECTION 338(h)(10) ELECTION.

     If directed by Eltrax, upon receipt of the payments described in this
Section 4.6, the Shareholders agree to make on behalf of Five Star, an election
under Section 338(h)(10) of the Code (the "Election"). In accordance with the
Treasury Regulations under Section 338(h)(10) of the Code, the Shareholders
acknowledge that as a result of making the Election the Five Star Purchase will
be treated for federal and state income tax purposes as a deemed sale of the
assets of Five Star for consideration equal to: (i) the purchase price allocated
to Five Star plus (ii) all liabilities of Five Star (the "Asset Purchase
Price"), followed by a deemed liquidation of Five Star.  In connection with the
deemed sale of assets by the Five Star, the Shareholders agree to allocate the
Asset Purchase Price in accordance with Eltrax's determination.  If as a result
of the Election, the Shareholders incur a Total Tax Liability (as defined below)
for Five Star greater than would otherwise result absent such Election
("Additional Tax"), then Eltrax will pay the Shareholders as additional
purchase price for Five Star, an amount equal to the Additional Tax, divided by
0.76376. "Total Tax Liability" includes the Shareholders' aggregate federal and
state tax liability, including any penalties, interest, fees or costs, arising
solely from the Five Star Purchase.

     4.7  NOMINATION TO ELTRAX BOARD.

          At the first meeting of the Board of Directors of Eltrax following the
Closing, Eltrax will arrange for Penelope Sellers to be nominated, and will
cause Penelope Sellers to be elected to the Board of Directors of Eltrax.

     4.8  POST-CLOSING MATTERS

          If prior to Closing the personal guaranties of Penelope Sellers, each
of which is specifically identified on Schedule 2.14, have not been terminated,
following the Closing the parties hereto will use their reasonable efforts to
obtain the termination of such guaranties.  Eltrax will indemnify Penelope
Sellers from any losses to Ms. Sellers arising out of or pertaining to such
guaranties.

     the either party resulting from a breach of the covenants contained in
     Section 4.6 shall not be subject to the provisions of this Section 8.5(a).

          (b)  Notwithstanding the foregoing, in the case of any untrue
     representation contained in Article 2 or Article 3 with respect to which
     any party had actual knowledge at the time of Closing that such
     representation was untrue, without disclosing such to the other party prior
     to the Closing Date, such non-disclosing party will promptly pay the other
     party the full indemnification claim for such loss, liability or damage,
     without regard to the Threshold Amount set forth in this Section, the
     overall limitation on amount as set forth in Section 8.4 or the time
     limitation set forth in Section 8.1; provided, however, that with respect
     to any obligation of the Shareholders, Penelope Sellers will pay ninety
     percent (90%) of such indemnification claim, and Joseph T. Dyer will pay
     ten percent (10%) of such indemnification claim, unless such
     indemnification arises under Section 2.19, in which case the loss shall be
     satisfied one hundred percent (100%) by the Shareholder subject to such
     claim but in no event shall any Shareholder's


                                      23
<PAGE>

     indemnification obligations pursuant to this Article 8 exceed the aggregate
     value of consideration received by such Shareholder (measured as to the 
     Closing) under this Agreement.

     8.6. CLAIMS FOR INDEMNIFICATION.

     The parties intend that all indemnification claims hereunder be made as
promptly as practicable by the party seeking indemnification (the "Indemnified
Party"). Whenever any claim arises for indemnification hereunder the Indemnified
Party will promptly notify the party from whom indemnification is sought (the
"Indemnifying Party") of the claim and, when known, the facts constituting the
basis for such claim; PROVIDED, HOWEVER, that any failure to give such claim
notice will not be deemed a waiver of any rights of the Indemnified Party except
to the extent the rights of the Indemnifying party are actually prejudiced by
such failure.  In the case of any such claim for indemnification hereunder
resulting from or in connection with any claim or legal proceedings of a third
party (a "Third Party Claim"), the notice to the Indemnifying Party will
specify, if known, the amount or an estimate of the amount of the liability
arising therefrom.  The Indemnifying Party shall have the right to dispute and
defend all Third Party Claims and thereafter so defend and pay any adverse final
judgment or award or settlement amount in regard thereto.  Such defense shall be
controlled by the Indemnifying Party, and the cost of such defense shall be
borne by the Indemnifying Party, except that the Indemnified Party shall have
the right to participate in such defense at its own expense; and PROVIDED,
HOWEVER that the Indemnifying Party must first acknowledge that the claim is a
bona fide indemnification claim under this Agreement.  The Indemnified Party
shall cooperate in all reasonable respects in the defense of any such claim,
including making personnel, books, and records relevant to the claim available
to the Indemnifying Party, without charge, except for reasonable out-of-pocket
expenses.  If the Indemnifying Party fails to take assume the defense of such
Third Party Claim within thirty (30) days as set forth above, then the
Indemnified Party shall have the right to pay, compromise or defend any Third
Party Claim and to assert the amount of any payment on the Third Party Claim
plus the reasonable expenses of defense or settlement as its claim for
indemnification.  The Indemnified Party shall also have the right, exercisable
in good faith, to take such action as may be necessary to avoid a default prior
to the assumption of the defense of the Third Party Claim by the Indemnifying
Party, and any reasonable expenses incurred by Indemnified Party so acting shall
be paid by the Indemnifying Party.  Except as otherwise provided herein, the
Indemnified Party will not settle or compromise any Third Party Claim the
defense of which has been assumed by the Indemnifying Party, without the prior
written consent of the Indemnifying Party, which will not be unreasonably
withheld.  If the Indemnifying Party is of the opinion that the Indemnified
Party is not entitled to indemnification, or is not entitled to indemnification
in the amount claimed in such notice, it will deliver, within twenty (20)
business days after the receipt of the initial claim notice, a written objection
to such claim and written specifications in reasonable detail of the aspects or
details objected to, and the grounds for such objection.  If the Indemnifying
Party filed timely written notice of objection to any claim for indemnification,
the validity and amount of such claim will be determined by arbitration pursuant
to Section 9.12 hereof.  In determining the damages suffered by an Indemnified
Party, there shall be no duplication of the amounts claimed for recovery (E.G. a
damage suffered by Acquiring Sub shall not result in an equal amount of damages
suffered by Encore). Unless otherwise set forth in this Agreement, the
indemnification provided in this Article 8 shall be the sole and exclusive
remedy of the parties.

                            MISCELLANEOUS PROVISIONS

     9.1. EXPENSES.

     Each of the parties hereto will bear its own costs, fees and expenses in
connection with the negotiation, preparation, execution, delivery and
performance of this Agreement and the consummation of the transactions
contemplated hereby, including without limitation fees, commissions and expenses
payable to brokers, finders, investment bankers, consultants, exchange or
transfer agents, attorneys, accountants and other professionals, and all Taxes,
whether or not the Transactions are consummated; provided however, (i) Eltrax
will pay all transfer taxes applicable to the Transactions, if any, and
(ii) subject to review of invoices and approval of Eltrax, the Companies will
pay the reasonable expenses and costs, including legal and accounting fees, to
be calculated on an hourly basis plus any out-of-pocket disbursements, of the
Companies and the Shareholders incurred in connection with the Transactions; and
provided further, all due diligence costs incurred by Roger Maloch shall be an
expense of the Shareholders directly and not paid by the Company and any
violation of this clause shall be treated as a direct reduction of the purchase
price of GSS and not subject to the threshold limitations of Section 8.5(a).

     9.2. AMENDMENT AND MODIFICATION.

     Subject to applicable law, this Agreement may be amended or modified by the
parties hereto at any time prior to the Closing with respect to any of the terms
contained herein; provided, however, that all such amendments and modifications
must be in writing duly executed by all of the parties hereto.

     9.3. WAIVER OF COMPLIANCE; CONSENTS.

     Any failure of a party to comply with any obligation, covenant, agreement
or condition herein may be expressly waived in writing by the party entitled
hereby to such compliance, but such waiver or failure to insist upon strict
compliance with such obligation, covenant, agreement or condition will not
operate as a waiver of, or estoppel with respect to, any subsequent or other
failure.  No single or partial exercise of a right or remedy will preclude any
other or further exercise thereof or of any other right or remedy hereunder.
Whenever this Agreement requires or permits the consent by or on behalf of a
party, such consent will be given in writing in the same manner as for waivers
of compliance.

     9.4. NO THIRD PARTY BENEFICIARIES.

     Nothing in this Agreement will entitle any person or entity (other than a
party hereto and his, her or its respective successors and assigns permitted
hereby) to any claim, cause of action, remedy or right of any kind.

     9.5. NOTICES.

     All notices, requests, demands and other communications required or
permitted hereunder will be made in writing and will be deemed to have been duly
given and effective:  (i) on the date of delivery, if delivered personally; (ii)
on the day following delivery, if sent by a nationally recognized overnight

permitted assigns, but neither this Agreement nor any of the rights, interests
or obligations hereunder may be assigned (whether voluntarily, involuntarily, by
operation of law or otherwise) by any of the parties hereto without the prior

of validity, construction, effect, performance and remedies.

     9.8. COUNTERPARTS.

     9.10.     ENTIRE AGREEMENT.

     The Schedules and the Exhibits and other writings referred to in this
Agreement, together with this Agreement embody the entire agreement and
understanding of the parties hereto in respect of the transactions contemplated
by this Agreement  and together they are referred to as "this Agreement" or the
"Agreement".  This Agreement, when fully executed by all parties, supersedes all
prior and contemporaneous oral and written agreements and understandings between
the parties with respect to the transaction or transactions contemplated by this
Agreement (including without limitation the letter of intent dated August 4,
1998 between Eltrax, Encore, and Shareholders and all amendments and extensions
thereof).

     9.11.     INJUNCTIVE RELIEF.

     It is expressly agreed among the parties hereto that monetary damages would
be inadequate to compensate a party hereto for any breach by any other party of
its covenants in Section 4.1.  Accordingly, the parties agree and acknowledge
that any such violation or threatened violation will cause irreparable injury to
the other and that, in addition to any other remedies which may be available,
such party will be entitled to injunctive relief against the threatened breach
of Section 4.1 hereof or the continuation of any such breach without the
necessity of proving actual damages and may seek specific enforcement of the
terms thereof.

     9.12.     ARBITRATION.

     With the sole exception of the injunctive relief contemplated by
Section 9.11 hereof, any controversy or claim arising out of or relating to this
Agreement, or the making, performance or interpretation hereof, including
without limitation alleged fraudulent inducement hereof, will be settled by
binding arbitration in Atlanta, Georgia by a panel of three arbitrators, of
which Eltrax will choose one arbitrator, the Shareholders will choose one
arbitrator, and those arbitrators will choose the third arbitrator, who will act
as chairman of the panel.  The arbitrators will select the rules and procedures
under which the arbitration will be conducted.  Judgment upon any arbitration
award may be entered in any court having jurisdiction thereof and the parties
consent to the jurisdiction of the courts of the State of Georgia for this
purpose.

     9.13.     ATTORNEYS' FEES.

     If any arbitration, litigation or similar proceedings are brought by any
party to enforce any obligation or to pursue any remedy under this Agreement,
the party prevailing in any such arbitration, litigation or similar proceedings
will be entitled to costs of collection, if any, and reasonable attorneys' fees
actually incurred in connection with such proceedings and in collecting or
enforcing any award granted therein.

     9.14.     KNOWLEDGE OF THE COMPANIES OR THE SHAREHOLDERS.

     Where any representation or warranty contained in this Agreement is
expressly qualified by reference to the knowledge of the Companies or the
Shareholders, such phrase will only include each Shareholder's actual present
knowledge of a particular matter.

     9.15.     VENUE AND JURISDICTION.

     The parties agree that all actions or proceedings arising in connection
with this Agreement and the instruments, agreements and documents executed
pursuant to the terms of this Agreement shall be tried, litigated and arbitrated
only in the courts of the United States located in the Northern District of
Georgia, the Georgia state courts, or at an arbitration venue located nearest
Atlanta, Georgia.  Each of the Companies, the Shareholders and Eltrax
irrevocably accept for itself or herself and in respect of its or her property,
generally and unconditionally, the jurisdiction of such courts.  Each of the
Companies, Shareholders and Eltrax irrevocably consent to the service of process
out of any such courts in any such action or proceeding by the mailing of copies
thereof by registered or certified mail, postage prepaid, to such party, at its
address as set forth in this Agreement, or in the records of the Surviving
Corporation, such service to become effective ten (10) days after such mailing.
Nothing in this Section 9.15 shall affect the right of any party to serve
process in any other manner permitted by law.  Each of the Companies, the
Shareholders and Eltrax irrevocably waive any right it or she may have to assert
the doctrine of forum non conveniens or to object to venue to the extent any
proceeding is brought in accordance with this Section 9.15.

                     EMPLOYMENT AND  NON-COMPETITION AGREEMENT

      THIS AGREEMENT (this "AGREEMENT") is dated as of August 31, 1998, and 
is between ENCORE SYSTEMS, INC., a Georgia corporation ("Encore" or the 
"Company") and wholly owned subsidiary of Eltrax Systems, Inc., ("Eltrax") 
and PENELOPE SELLERS, an individual residing in the State of Georgia 
("Employee").  The parties agree as follows:

                                         1.
                            EMPLOYMENT, DUTIES AND TERM

1.1.  EMPLOYMENT; POSITION.  Upon the terms and conditions set forth in this
      Agreement, the Company hereby employs Employee as President of Encore and

and performed in accordance with GAAP, and all financial data required to be 
delivered hereunder shall be prepared in accordance with GAAP.

     2.   LOAN FACILITY.

     (a)  REVOLVING CREDIT FACILITY.

          (i)    REVOLVING CREDIT LOANS.  Upon the terms and subject to the 
     conditions of this Agreement, the Bank agrees to lend to the Borrowers 
     such sums that the Borrowers may request, from the date hereof until but 
     not including the Maturity Date, provided that the sum of the outstanding 
     principal amount of all Revolving Credit Loans (after giving effect to all
     amounts requested) shall not exceed the lesser of (i) the Borrowing Base 
     and (ii) the Revolver Commitment Amount.

          (ii)   INTEREST.  Each Revolving Credit Loan shall bear interest at 
     a per annum rate equal to the Prime Rate plus one percent (1.0%). Borrowers
     promise and agree to pay all accrued interest on each Revolving Credit Loan
     in arrears on each Interest Payment Date at the Applicable Rate for such 
     Interest Period.  Each change in such interest rate shall take effect 
     simultaneously with the corresponding change in the Prime Rate.

          (iii)  NOTICES.  The Borrower shall notify the Bank in writing not 
     later than 10:00 a.m. (Boston time) on the date of the Revolving Credit 
     Loan being requested of the Drawdown Date (which must be a Business Day) 
     and the principal amount of such Revolving Credit Loan.  Subject to the 
     foregoing, so long as the Revolving Credit Commitment is then in effect 
     and the conditions set forth in Sections 5(a) and (b), as applicable, 
     hereof have been met, the Bank shall advance the amount requested to 
     Borrowers' account(s) at the Bank in immediately available funds not 
     later than the close of business on such Drawdown Date.

          (iv)   REVOLVING CREDIT NOTE.  The Revolving Credit Loans shall be 
     evidenced by an amended and restated promissory note of the Borrowers in 
     substantially the form of EXHIBIT E hereto (the "Revolving Credit Note"),
     dated as of the date hereof and completed with appropriate insertions, 
     which Revolving Credit Note shall be due and payable in full on the 
     Maturity Date.  The Borrowers irrevocably authorize the Bank to make or 
     cause to be made, at the time of receipt of any advance on or payment of 
     principal under the Revolving Credit Note, an appropriate notation on the 
     Bank's Record reflecting the advance or receipt of  such payment.  The 
     outstanding amount of the Revolving Credit Loans set forth on the Bank's 
     Record shall be prima facie evidence of the principal amount thereof owing 
     and unpaid to the Bank, but the failure to record, or any error in so 


12
<PAGE>

     recording, any such amount on the Bank's Record shall not limit or 
     otherwise affect the obligations of the Borrowers hereunder or under the 
     Revolving Credit Note to make payments of principal of or interest on 
     the Revolving Credit Note when due.

          (v)    PAYMENT ON MATURITY DATE. The Borrowers hereby agree to pay 
     the Bank on the Maturity Date the entire unpaid principal of and 
     interest on all Revolving Credit Loans.

          (vi)   PREPAYMENT AND REPAYMENT. On and subject to the payments of 
     the amounts due, if any, under the provisions of Sections 2(c) and 2(k) 
     of this Agreement, the Borrowers may repay or prepay the outstanding 
     principal of all or any part of any Revolving Credit Loan, by 10:00 a.m. 
     (Boston time) on any Business Day.  The Borrowers shall be entitled to 
     reborrow before the Maturity Date such repaid or prepaid amounts, upon 
     the terms and subject to the conditions of this Agreement.  Except as 
     provided in Section 2(c)(iii) below, no repayment of principal under any 
     Revolving Credit Loan shall cause Borrowers to incur any Prepayment 
     Penalty, as defined herein. All payments in respect of any Revolving 
     Credit Loans shall be applied first to accrued and unpaid interest on 
     the Revolving Credit Loans and then to outstanding principal on such 
     Revolving Credit Loans.

          (vii)  EXCESS ADVANCES.  If at any time the outstanding principal 
     amount of the Revolving Credit Loans shall exceed the Borrowing Base, 
     the Borrower shall immediately pay the amount of such excess to the Bank 
     for application to the Revolving Credit Loans.

          (viii) USE OF PROCEEDS.  The proceeds of the Revolving Credit Loans 
     will be used to repay existing revolving credit loans made by the Bank, 
     if any, and to provide working capital and funds for Acquisitions, to 
     the extent permitted pursuant to Section 6(m) hereof, to the Borrowers.  
     No part of such proceeds will be used for the purpose of purchasing or 
     carrying any "margin securities" as such term is defined in Regulation U 
     of the Board of Governors of the Federal Reserve System.

     (b)  TERM LOAN FACILITY.

          (i)    AMOUNT OF TERM LOAN.  Subject to the terms and conditions 
     hereof, the Bank shall advance to Borrowers on the Closing Date, the 
     Term Loan in an amount of Four Million Dollars ($4,000,000).  Principal 
     amounts prepaid or repaid under the Term Loan may not be reborrowed by 
     the Borrowers.

          (ii)   INTEREST.  To the extent that for any Interest Period, the 
     Term Loan is a Prime Rate Loan, the Term Loan shall bear interest during 
     such Interest Period at the Prime Rate plus one and one-half percent 
     (1.5%) per annum.  Each change in such interest rate shall take effect 
     simultaneously with the corresponding change in the Prime Rate.  To the 
     extent that for any Interest Period, the Term Loan is a Libor Rate Loan, 
     the Term Loan shall bear interest during such Interest Period at a rate 
     of 425 basis points 


13
<PAGE>

     above the Libor Rate determined for such Interest Period.  The Borrower 
     promises and agrees to pay interest on the Term Loan in arrears on the 
     date provided in subsection (vi) below at the Applicable Rate for such 
     Interest Period.

          (iii)  CONVERSION.  The Borrower may elect from time to time to 
     convert the entire outstanding principal balance of the Term Loan to 
     another Type, provided that (A) with respect to any such conversion from 
     a Libor Rate Loan to a Prime Rate Loan, the Borrower shall give the Bank 
     at least three (3) Business Days' prior written notice of such election 
     (each a "Conversion Request"); and such conversion shall only be made on 
     the last day of the Interest Period with respect thereto; and (B) with 
     respect to such conversion from a Prime Rate Loan to a Libor Rate Loan, 
     the Borrower shall give the Bank at least three (3) Business Days' prior 
     written notice of such election and no Prime Rate Loan may be converted 
     into a Libor Rate Loan when any Default or Event of Default has occurred 
     and is continuing. Each Conversion Request relating to the conversion of 
     a Prime Rate Loan to a Libor Rate Loan shall be irrevocable by the 
     Borrower.

          (iv)   CONTINUATION.  Except as limited by the provisions of 
     subsection (iii) above, a Loan of any Type may be continued as such upon 
     the expiration of an Interest Period with respect thereto by compliance 
     by the Borrower with the notice provisions contained in subsection 
     (iii); PROVIDED that no Libor Rate Loan may be continued as such when 
     any Default or Event of Default has occurred and is continuing, but 
     shall be automatically converted to a Prime Rate Loan on the last day of 
     the first Interest Period relating thereto ending during the continuance 
     of any Default or Event of Default of which the officers of the Bank 
     active upon the Borrower's account have actual knowledge.  In the event 
     that the Borrowers do not notify the Bank of their election hereunder 
     with respect to the Term Loan or portion thereof, such Loan or portion 
     thereof shall be automatically converted to a Prime Rate Loan at the end 
     of the applicable Interest Period.

          (v)    AUTHORIZATION AND ISSUANCE OF TERM NOTE.  The Term Loan 
     shall be evidenced by a promissory note of the Borrowers in 
     substantially the form of EXHIBIT F hereto (the "Term Note"), dated as 
     of the date hereof and completed with appropriate insertions, which Term 
     Note shall be due and payable in full on the Maturity Date.  The 
     Borrowers irrevocably authorize the Bank to make or cause to be made, at 
     the time of receipt of any advance on or payment of principal under the 
     Term Note, an appropriate notation on the Bank's Record reflecting the 
     advance or receipt of  such payment.  The outstanding amount of the Term 
     Loan set forth on the Bank's records shall be prima facie evidence of 
     the principal amount thereof owing and unpaid to the Bank, but the 
     failure to record, or any error in so recording, any such amount on the 
     Bank's Record shall not limit or otherwise affect the obligations of the 
     Borrowers hereunder or under the Term Note to make payments of principal 
     of or interest on the Term Note when due.

          (vi)   PAYMENT.  Borrowers shall make monthly payments of principal 
     of the Term Loan in the amount of $111,111 plus accrued interest thereon 
     at the Applicable 


14
<PAGE>

     Rate commencing on the first day of the month following the Closing Date 
     and continuing on the first day of each month thereafter until the 
     Maturity Date.  Borrowers shall also make annual prepayments of 
     principal of the Term Loan within 120 days after the end of Borrowers' 
     fiscal year equal to fifty percent (50%) of Excess Cash Flow for such 
     fiscal year (each a "Mandatory Prepayment").  The making of any 
     Mandatory Prepayment shall not cause Borrowers to incur any Prepayment 
     Penalty, as defined herein.  Each Mandatory Prepayment will be applied 
     to scheduled payments under the Term Loan in inverse order of maturity.  
     The entire remaining outstanding principal balance of the Term Loan, if 
     any, together with all accrued and unpaid interest, shall be due and 
     payable on the Maturity Date.  Principal amounts repaid under the Term 
     Loan may not be reborrowed by Borrowers.

          (vii)  PREPAYMENT AND REPAYMENT.  Subject to the payments of the 
     amounts due, if any, under the provisions of Sections 2(c) and 2(k) of 
     this Agreement, the Borrowers may repay or prepay the outstanding 
     principal of all or any part of the Term Loan, by 10:00 a.m. (Boston 
     time) on any Business Day, in the case of a Prime Rate Loan, or upon 
     written notice given by 10:00 a.m. (Boston time) at least three (3) 
     Business Days, in the case of a Libor Rate Loan, prior to the date of 
     such prepayment, of the amount to be prepaid and the date of such 
     prepayment.

          (viii) USE OF PROCEEDS.  The proceeds of the Term Loan will be used 
     to provide working capital and funds for Acquisitions, to the extent 
     permitted pursuant to Section 6(m) hereof, to the Borrowers.  No part of 
     such proceeds will be used for the purpose of purchasing or carrying any 
     "margin securities" as such term is defined in Regulation U of the Board 
     of Governors of the Federal Reserve System.

      (c) FEES AND PAYMENTS.

          (i)    CLOSING FEE.  Borrowers shall pay to the Bank a fee (the 
     "Closing Fee") of $150,000 payable in monthly installments equal to 
     one-half of one percent (0.5%) of the combined monthly net sales of the 
     Borrowers for each month from and after January 1, 1999 until paid in 
     full. The Closing Fee shall be paid monthly in arrears commencing on 
     February 26, 1999 (for the month of January 1999) and thereafter on the 
     last Business Day of each calendar month.  Any unpaid balance of the 
     Closing Fee shall be due and payable in full upon (i) acceleration of 
     the Obligations following an Event of Default or (ii) prepayment in full 
     of the Loans and termination of the Commitment pursuant to Section 2(k) 
     of this Agreement.

          (ii)   COMMITMENT FEE.  At all times prior to termination of the 
     Commitment, the Borrowers shall pay to the Bank, a fee (the "Commitment 
     Fee") of one-quarter of one percent (0.25%) per annum of the difference 
     between the amount of the Revolver Commitment Amount and the sum of the 
     daily average principal amount of the Revolving Credit Loans outstanding 
     from time to time.  The Commitment Fee shall be calculated quarterly in 
     arrears commencing on September 30, 1998 (for the period from the date 
     hereof through September 30, 1998) and thereafter on the last day of each


15

<PAGE>

     calendar quarter and on any other date the Commitment is terminated.  The
     Commitment Fee shall be due and payable on the last day of each quarter.

          (iii)  PREPAYMENT FEE.  Borrowers shall pay the Bank a prepayment
     penalty (the "Prepayment Penalty"), payable in the event the Loans are
     prepaid for any reason, whether voluntarily, after an Event of Default,
     upon acceleration or otherwise (except as provided in the last paragraph of
     this subsection or as otherwise provided in this Credit Agreement),
     calculated as follows:

                 (A)  If Borrowers make prepayment before the one (1) year
          anniversary of the Closing Date, the Prepayment Penalty shall be equal
          to two percent (2%) of the Commitment Amount.

                 (B)  If Borrowers make prepayment at any time during the six
          (6) month period beginning on the (1) year anniversary of the Closing
          Date, the Prepayment Penalty shall be equal to one percent (1%) of the
          Commitment Amount.

                 (C)  If Borrowers make prepayment on the date eighteen (18)
          months after the Closing Date or at any time thereafter, there shall
          be no Prepayment Penalty.

     Notwithstanding anything to the contrary in this subsection (iii), there
     shall be no Prepayment Penalty: (x) on Mandatory Prepayments of the Term
     Loan, (y) on prepayments made entirely with funds generated from operations
     of the Borrowers and/or a public or private offering, rather than as a
     result of or with proceeds of any new indebtedness of the Borrowers to
     another bank or other institutional lender, or (z) if the Borrowers request
     the Bank to provide additional financing, the Bank declines to provide such
     financing and thereafter the Borrowers obtain such financing from another
     source and prepay the Loans in full with the proceeds thereof.

          (iv)   PAYMENTS.  All payments of principal, interest, Closing Fee,
     Commitment Fee, Prepayment Fee and any other amounts due hereunder or under
     any of the other Loan Documents shall be made to the Bank at its principal
     office at 225 Franklin Street, Boston, Massachusetts 02110, or at such
     other location that the Bank may from time to time designate, in each case
     in immediately available funds.

          (v)    NO SET OFF, ETC.  All payments by the Borrowers hereunder and
     under any of the other Loan Documents shall be made without setoff or
     counterclaim and free and clear of and without deduction for any taxes,
     levies, imposes, duties, charges, fees, deductions, withholdings,
     compulsory loans, restrictions or conditions of any nature now or hereafter
     imposed or levied by any jurisdiction or any political subdivision thereof
     or taxing or other authority therein unless the Borrowers are compelled by
     law to make such deduction or withholding.  If any such obligation is
     imposed upon the Borrowers with respect to any amount payable by it
     hereunder or under any of the other Loan Documents, 

16

<PAGE>

     the Borrowers will pay to the Bank, on the date on which such amount is 
     due and payable hereunder or under such other Loan Document, such 
     additional amount in Dollars as shall be necessary to enable the Bank to 
     receive the same net amount which the Bank would have received on such 
     due date had no such obligation been imposed upon the Borrowers.  The 
     Borrowers will deliver promptly to the Bank certificates or other valid 
     vouchers for all taxes or other charges deducted from or paid with 
     respect to payments made by the Borrowers hereunder or under such other 
     Loan Document.

     (d)  COMPUTATIONS.  All computations of interest on the Loans and of other
fees to the extent applicable shall be based on a 360-day year and paid for the
actual number of days elapsed.  Except as otherwise provided in the definition
of the term "Interest Period" with respect to Libor Rate Loans, whenever a
payment hereunder or under any of the other Loan Documents becomes due on a day
that is not a Business Day, the due date for such payment shall be extended to
the next succeeding Business Day, and interest shall accrue during such
extension.  The outstanding amount of the Loans as reflected on the Bank's
Record from time to time shall be considered correct and binding on the
Borrowers unless within ten (10) Business Days after receipt by the Bank from
the Borrowers of any notice of such outstanding amount, the Bank shall notify
the Borrowers to the contrary.

     (e)  INABILITY TO DETERMINE LIBOR RATE.  In the event, prior to the
commencement of any Interest Period relating to a Libor Rate Loan, the Bank
shall determine that adequate and reasonable methods do not exist for
ascertaining the Libor Rate that would otherwise determine the rate of interest
to be applicable to a Libor Rate Loan during any Interest Period, the Bank shall
forthwith give notice of such determination (which shall be conclusive and
binding on the Borrowers) to the Borrowers.  In such event (i) any Conversion
Notice with respect to a Libor Rate Loan shall be automatically withdrawn and
shall be deemed a request for a Prime Rate Loans, (ii) each Libor Rate Loan will
automatically, on the last day of the then current Interest Period thereof,
become a Prime Rate Loan, and (iii) the obligations of the Bank to make Libor
Rate Loans shall be suspended until the Bank determines that the circumstances
giving rise to such suspension no longer exist, whereupon the Bank shall so
notify the Borrowers.

     (f)  ILLEGALITY.  Notwithstanding any other provisions herein, if any
present or future law, regulation, treaty or directive or in the interpretation
or application thereof shall make it unlawful for the Bank to make or maintain
Libor Rate Loans, the Bank shall forthwith give notice of such circumstances to
the Borrower and thereupon (a) the commitment of the Bank to make Libor Rate
Loans or convert Loans of another Type to Libor Rate Loans shall forthwith be
suspended and (b) the Libor Rate Loans then outstanding shall be converted
automatically to Prime Rate Loans on the last day of each Interest Period
applicable to such Libor Rate Loans or within such earlier period as may be
required by law.  The Borrowers hereby agree promptly to pay the Bank, upon
demand by the Bank, any additional amounts necessary to compensate the Bank for
any costs incurred by the Bank in making any conversion in accordance with this
Section 2(f), including any interest or fees payable by the Bank to lenders of
funds obtained by it in order to make or maintain its Libor Rate Loans
hereunder.

     (g)  ADDITIONAL COSTS, ETC.  If any present or future applicable law, which
expression, 

17

<PAGE>

as used herein, includes statutes, rules and regulations thereunder and 
interpretations thereof by any competent court or by any governmental or 
other regulatory body or official charged with the administration or the 
interpretation thereof and requests, directives, instructions and notices at 
any time or from time to time hereafter made upon or otherwise issued to the 
Bank by any central bank or other fiscal, monetary or other authority 
(whether or not having the force of law), shall:

          (i)    Subject the Bank to any tax, levy, impost, duty, charge, fee,
     deduction or withholding of any nature with respect to this Agreement, the
     other Loan Documents, the Commitment or the Loans (other than taxes based
     upon or measured by the income or profits of the Bank); or

          (ii)   Materially change the basis of taxation (except for changes in
     taxes on income or profits) of payments to the Bank of the principal of or
     the interest on any Loans or any other amounts payable to the Bank under
     this Agreement or the other Loan Documents; or

          (iii)  Impose or increase or render applicable (other than to the
     extent specifically provided for elsewhere in this Agreement) any special
     deposit, reserve, assessment, liquidity, capital adequacy or other similar
     requirements (whether or not having the force of law) against assets held
     by, or deposits in or for the account of, or loans by, or commitments of an
     office of the Bank; or

          (iv)   Impose on the Bank any other conditions or requirements with
     respect to this Agreement, the other Loan Documents, the Loans, the
     Commitment, or any class of loans or commitments of which any of the Loans
     or the Commitment forms a part; and the result of any of the foregoing is:

                 (A)  to increase the cost to the Bank of making, funding,
          issuing, renewing, extending or maintaining any of the Loans or the
          Commitment; or

                 (B)  to reduce the amount of principal, interest or other
          amount payable to the Bank hereunder on account of the Commitment or
          any of the Loans; or

                 (C)  to require the Bank to make any payment or to forego any
          interest or other sum payable hereunder, the amount of which payment
          or foregone interest or other sum is calculated by reference to the
          gross amount of any sum receivable or deemed received by the Bank from
          the Borrowers hereunder,

     then, and in each such case, the Borrowers will, upon demand made by the
     Bank at any time and from time to time and as often as the occasion
     therefor may arise, pay to the Bank such additional amounts as will be
     sufficient to compensate the Bank for such additional cost, reduction,
     payment or foregone interest or other sum.  The Bank shall use reasonable
     efforts to provide the Borrowers with prompt notice of any such additional
     amounts which are or will become due hereunder.

18

<PAGE>

     (h)  CAPITAL ADEQUACY.  If any present or future law, governmental rule, 
regulation, guideline or directive (whether or not having the force of law) 
or the interpretation thereof by a court or governmental authority with 
appropriate jurisdiction affects the amount of capital required or expected 
to be maintained by the Bank or any corporation controlling the Bank and the 
Bank determines that the amount of capital required to be maintained by it is 
increased by or based upon the existence of the Loan made or deemed to be 
made pursuant hereto, then the Bank may notify the Borrowers of such fact, 
and the Borrowers shall pay to the Bank from time to time on demand, as an 
additional fee payable hereunder, such amount as the Bank shall determine in 
good faith and certify in a notice to the Borrowers to be an amount that will 
adequately compensate the Bank in light of these circumstances for its 
increased costs of maintaining such capital.  The Bank shall allocate such 
cost increases among its customers in good faith and on an equitable basis.

     (i)  CERTIFICATE.  A certificate setting forth any additional amounts
payable pursuant to Section 2(g) or 2(h) and a brief explanation of such amounts
which are due, submitted by the Bank to the Borrowers, shall be prima facie
evidence that such amounts are due and owing.

     (j)  INDEMNITY.  The Borrowers agree to indemnify the Bank and to hold the
Bank harmless from and against any loss, cost or expense (including loss of
anticipated profits) that the Bank may sustain or incur as a consequence of: (i)
default by the Borrowers in payment of the principal amount of or any interest
on any Libor Rate Loans as and when due and payable, including any such loss or
expense arising from interest or fees payable by the Bank to lenders of funds
obtained by it in order to maintain its Libor Rate Loans, (ii) default by the
Borrowers in making a borrowing or conversion after the Borrowers have given (or
are deemed to have given) a Conversion Request, or (iii) the making of any
payment of a Libor Rate Loan or the making of any conversion of any such Libor
Rate Loan to a Prime Rate Loan on a day that is not the last day of the
applicable Interest Period with respect thereto, including interest or fees
payable by the Bank to lenders of funds obtained by it in order to maintain any
such Loans.

     (k)  TERMINATION OF COMMITMENT. The Borrowers may elect to permanently
terminate the Commitment upon written notice to the Bank given by 10:00 a.m.
(Boston time) at least three (3) Business Days prior to the date of such
termination, and by making on such termination date payment in full to the Bank
of all amounts due and payable under and on account of the Obligations,
including but not limited to all principal, accrued interest, accrued facility
fees and any other amounts due hereunder including, but not limited to, amounts
due under the provisions of Section 2(c) hereof.  The Borrower shall not be
entitled to reinstate the Commitment following such termination.

     (l)  APPOINTMENT OF ELTRAX AS AGENT OF BORROWERS.  Each of the Borrowers
hereby authorizes and appoints Eltrax as its agent for purposes of giving and
receiving all notices and making all borrowing requests, interest rate
determinations, conversion requests, prepayment and repayments, and other
actions on behalf of or required of the Borrowers under this Agreement,
including, without limitation, with respect to all matters set forth in this
Section 2. The Bank may conclusively rely on all such requests, determinations
and notifications made by Eltrax with respect to each of the Borrowers.

     3.   INTEREST AFTER DEFAULT; LATE FEE.  While an Event of Default is
continuing, amounts payable under any of the Loan Documents shall bear interest
(compounded monthly and payable on demand in respect of overdue amounts) at a
rate per annum which is equal to two percent (2%) above the rate otherwise in
effect for such amounts, until such amount is paid in full or (as the case may
be) such Event of Default has been waived in writing by the Bank (after as well
as before judgment).

     4.   REPRESENTATIONS AND WARRANTIES OF THE BORROWERS. The Borrowers hereby
represent, warrant and covenant to the Bank that:

     (a)  CORPORATE EXISTENCE.  Each Borrower and each of its Subsidiaries is 
a corporation duly incorporated and validly existing under the laws of the 
jurisdiction of its incorporation, and is duly licensed or qualified as a 
foreign corporation in all states wherein the nature of its property owned or 
business transacted by it makes such licensing or qualification necessary, 
except where the failure to be licensed or to so qualify could not have a 
Material Adverse Effect.  In addition, each Borrower and each of its 
Subsidiaries holds all licenses, permits and approvals from Governmental 
Authorities necessary or appropriate for the conduct of their businesses as 
currently conducted or currently contemplated to be conducted in the future. 
All such licenses, permits and approvals are in full force and effect and no 
action has been taken or threatened to be taken to dissolve, cancel or 
restrict any such license, permit or approval.

     (b)  NO VIOLATION  Neither the execution, delivery or performance of 
this Agreement or any other Loan Document, nor the consummation of the 
transactions herein or therein contemplated, will contravene any provision of 
law, statute, rule or regulation to which any Borrower or any of its 
Subsidiaries is subject or any judgment, decree, franchise, order, license or 
permit applicable to any Borrower or any of its Subsidiaries, or will 
conflict or will be inconsistent with or will result in any breach of, any of 
the terms, covenants, conditions or provisions of, or constitute a default 
under, or result in the creation or imposition of (or the obligation to 
create or impose) any Lien (other than the lien created by the Security 
Documents) upon any of the property or assets of any Borrower or any of its 
Subsidiaries pursuant to the terms of any contractual obligation of any 
Borrower or any of its Subsidiaries, or violate any provision of the 
corporate charter or by-laws of the Borrower or any of its Subsidiaries.

     (c)  CORPORATE AUTHORITY AND POWER.  The execution, delivery and
performance of this Agreement and the other Loan Documents are within the
corporate powers of the Borrowers and have been duly authorized by all necessary
corporate action.

     (d)  ENFORCEABILITY.  This Agreement and each other Loan Document
constitutes a valid and binding obligation of the Borrowers enforceable against
the Borrowers in accordance with its terms, except as enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting the enforcement of creditors' rights generally and except
as enforceability may be subject to general principles of equity, whether such
principles are applied in a court of equity or at law.

20

<PAGE>

     (e)  GOVERNMENTAL APPROVALS.  No order, permission, consent, approval,
license, authorization, registration or validation of, or filing with, or
exemption by, any Governmental Authority is required to authorize, or is
required in connection with, the execution, delivery and performance by the
Borrowers of this Agreement or any other Loan Document, or the taking of any
action contemplated hereby or thereby, except for the filing of UCC-1 financing
statements in the appropriate Uniform Commercial Code filing offices.

     (f)  FINANCIAL STATEMENTS.

          (i)    Eltrax has heretofore furnished, or will before the Closing
     Date furnish, the Bank with complete and correct copies of: (A) its audited
     consolidated balance sheet as of December 31, 1997, examined by the
     Accountants, and its unaudited consolidated balance sheet as of June 30,
     1997 (the "Financial Statement Date"); (B) the related audited consolidated
     statements of income and of cash flows for the fiscal year of Eltrax ended
     on December 31, 1997, examined by the Accountants, and its unaudited
     consolidated statements of income and cash flows for the period ending on
     the Financial Statement Date; (C) the balance sheets as of December 31,
     1997 and statements of income and cash flows for the period ending December
     31, 1997, of Encore and GSS, respectively, reviewed by the accountants for
     such companies; and (D) the tax basis balance sheet and statement of income
     internally prepared by Five Star and dated December 31, 1997.  Such
     financial statements (including in each case the related schedules and
     notes) fairly present the consolidated financial condition of the
     respective Borrowers as of the stated dates, and as applicable, the
     consolidated results of their operations and cash flows for the respective
     periods then ended.

          (ii)   None of the Borrowers nor any of their Subsidiaries has any
     material liabilities, contingent or otherwise, including liabilities for
     taxes or any unusual forward or long-term commitments or any Guaranty,
     which are not disclosed by or included in the financial statements referred
     to above or in the notes thereto, and there are no unrealized or
     anticipated losses from any unfavorable commitments of the Borrowers or any
     of their Subsidiaries which may have a Material Adverse Effect.  During the
     period from the Financial Statement Date to the date hereof: (x) there has
     been no sale, transfer or other disposition by the Borrowers or any of
     their Subsidiaries of any material part of their business or property and
     no purchase or other acquisition of any business or property (including any
     capital stock of any Person) material in relation to the consolidated
     financial condition of the Borrowers and their subsidiaries at the
     Financial Statement Date, other than the acquisition by Eltrax of all of
     the capital stock of Encore, GSS and Five Star, respectively; and (y) none
     of the Borrowers nor any of their Subsidiaries has made, or agreed or
     committed itself to make any Stockholder Distribution.

          (iii)  All financial statements (including in each case the related
     schedules and notes) referred to above, except for the Five Star statements
     prepared on a tax basis, have been prepared in accordance with GAAP applied
     consistently throughout the periods involved (except as approved by the
     Accountants and as disclosed therein).

21

<PAGE>

     (g)  NO CHANGE.  Since the Financial Statement Date there has been no
development or event, nor any prospective development or event, which has had or
could have a Material Adverse Effect.

     (h)  LITIGATION.  There are no actions, suits or proceedings pending or
threatened against or affecting the Borrowers or any of their Subsidiaries
before any Governmental Authority, which in any one case or in the aggregate, if
determined adversely to any interests of the Borrower or any Subsidiary, would
have a Material Adverse Effect.

     (i)  COMPLIANCE WITH OTHER INSTRUMENTS; COMPLIANCE WITH LAW.

          (i)    None of the Borrowers nor any of their Subsidiaries is in
     default under (A) any contractual obligation, where such default could have
     a Material Adverse Effect, or (B) the terms of any agreements relating to
     any Indebtedness of any Borrower or any such Subsidiary.

          (ii)   None of the Borrowers nor any of their Subsidiaries is in
     default with respect to any applicable statute, rule, writ, injunction,
     decree, order or regulation of any Governmental Authority having
     jurisdiction over the Borrowers or any of their Subsidiaries which could
     have a Material Adverse Effect.

     (j)  SUBSIDIARIES.   Except as set forth on Schedule 4(j) hereto, no
Borrower has any Subsidiaries on the date hereof.

     (k)  SUBSIDIARY TRANSACTIONS. Except as set forth on Schedule 4(k) hereto,
no Subsidiary of any Borrower engages, directly or indirectly in any transaction
with any Affiliate of that Borrower.

     (l)  INVESTMENT COMPANY STATUS; LIMITS ON ABILITY TO INCUR INDEBTEDNESS.
None of the Borrowers nor any of their Subsidiaries is an "investment company"
or a company "controlled by" an investment company within the meaning of the
Investment Company Act of 1940, as amended.  No Borrower is subject to
regulation under any Federal or State statute or regulation which limits its
ability to incur Indebtedness.

     (m)  TITLE TO PROPERTY.  Each Borrower and each of its Subsidiaries has
good and marketable title to all of its properties and assets, in each case
including the properties and assets reflected in the consolidated balance sheet
of the Borrowers as of the Financial Statement Date, except properties and
assets disposed of since that date in the ordinary course of business, and none
of such properties or assets is subject to (i) any Lien except for Liens
described on Schedule 6(p) hereof, or (ii) a defect in title or other claim
other than defects and claims that, in the aggregate, would have no Material
Adverse Effect.  Each Borrower and each of its Subsidiaries enjoys peaceful and
undisturbed possession under all leases necessary in any material respect for
the operation of its properties and assets, none of which contains any unusual
or burdensome provisions which might materially affect or impair such properties
or assets.  All such leases are 

22

<PAGE>

valid and subsisting and are in full force and effect.

     (n)  ERISA PLANS.  Each of the Borrowers has provided the Bank with a list
of each "employee benefit plan," "employee pension benefit plan," "defined
benefit plan," or multiemployer plan," which any Borrower or any Subsidiary
thereof has established or maintained or to which any Borrower or any of its
Subsidiaries is required to contribute (collectively, the "Plans").  Each such
Plan is in compliance in all material respects with all applicable provisions of
ERISA and the Code, and the rules and regulations thereunder, except where
failure to so comply would not have a Material Adverse Effect.  There have been
no "prohibited transactions" under ERISA with respect to the Plans which would
result in any material liability to any Borrower or any Subsidiary thereof under
ERISA or the Code.  As used in the Loan Documents, the terms "employee benefit
plan," "employee pension benefit plan," "defined benefit plan," and
"multiemployer plan" shall have the respective meanings assigned to such terms
in Section 3 of ERISA.  None of the Borrowers nor any Subsidiaries thereof has
incurred any material "accumulated funding deficiency" within the meaning of
ERISA or incurred any material liability to the PBGC in connection with a Plan
(or other class of benefit which the PBGC has elected to insure) established or
maintained by any of the Borrowers or any Subsidiary thereof.

     (o)  TAXES.  Except as set forth on Schedule 4(o) hereto, all tax returns
of the Borrowers and their Subsidiaries required to be filed have been filed,
all taxes, fees and other governmental charges (other than those being contested
in good faith by appropriate proceedings diligently conducted and with respect
to which adequate reserves have been established and, in the case of ad Valorem
taxes or betterment assessments, no proceedings to foreclose any lien with
respect thereto have been commenced and, in all other cases, no notice of lien
has been filed or other action taken to perfect or enforce such lien) shown
thereon which are payable have been paid.  The charges and reserves on the books
of the Borrowers and their Subsidiaries in respect of all income and other taxes
are adequate, and the Borrower knows of no additional assessment or any basis
therefor.  The Federal income tax returns of the Borrowers and their
Subsidiaries have not been audited within the last three years, all prior audits
have been closed, and there are no unpaid assessments, penalties or other
charges arising from such prior audits.

     (p)  ENVIRONMENTAL MATTERS.

          (i)    The Borrowers and each of their Subsidiaries have obtained all
     Governmental Approvals that are required with respect to the operation of
     their business under any Environmental Law.

          (ii)   The Borrowers and each of their Subsidiaries are in compliance
     with all terms and conditions of all required Governmental Approvals and is
     also in compliance with all other limitations, restrictions, conditions,
     standards, prohibitions, requirements, obligations, schedules and
     timetables contained in all applicable Environmental Laws.

          (iii)  There is no civil, criminal or administrative action, suit,
     demand, claim, hearing, notice of violation, investigation, proceeding,
     notice or demand letter pending or 

23

<PAGE>

     threatened against any Borrower or any Subsidiary thereof relating in 
     any way to the Environmental Laws, and there is no Lien of any private 
     entity or Governmental Authority against any property of any Borrower 
     or any Subsidiary thereof relating in any way to the Environmental Laws.
     
          (iv)   There has been no claim, complaint, notice, or request for 
     information-nation received by any Borrower or any of its Subsidiaries 
     with respect to any site listed on the National Priority List 
     promulgated pursuant to the Comprehensive Environmental Response, 
     Compensation, and Liability Act ("CERCLA"), 42 USC 9601 et seq. or any 
     state list of sites requiring investigation or cleanup with respect to 
     contamination by Hazardous Substances.
     
          (v)    To the best of the Borrowers' knowledge, after reasonable 
     investigation, there has been no release or threat of release of any 
     Hazardous Substance at any property owned or leased or occupied by any 
     Borrower or any of its Subsidiaries which would likely result in 
     liability being imposed upon such Borrower or such Subsidiary thereof.

     (q)  SOLVENCY.  Each of the Borrowers other than Nordata, Inc. has 
assets (both tangible and intangible) having a fair saleable value in excess 
of the amount required to pay the probable liability on its respective 
existing debts (whether matured or unmatured, liquidated or unliquidated, 
fixed or contingent); each of the Borrowers other than Nordata, Inc. has 
access to adequate capital for the conduct of its business and the discharge 
of its debts incurred in connection therewith as such debts mature; and none 
of the Borrowers other than Nordata, Inc. is insolvent nor was it insolvent, 
immediately prior to the initial consummation of the Loans.

     5.   CONDITIONS PRECEDENT.

     (a)  CONDITIONS TO THE LOANS. The obligations of the Bank to make the Term
Loan and the first Revolving Credit Loan are subject to the satisfaction of all
of the following conditions:

          (i)    LOAN DOCUMENTS.  Each of the Loan Documents shall have been
     duly executed and delivered by the respective parties thereto and, shall be
     in full force and effect and shall be in form and substance satisfactory to
     the Bank.  The Bank shall have received a fully executed copy of each such
     document.

          (ii)   CERTIFIED COPIES OF ORGANIZATION DOCUMENTS.  The Bank shall
     have received from each Borrower a copy, certified as of a recent date by
     the appropriate officer of the state in which each Borrower is organized to
     be true and complete, of the corporate charter and any other organization
     documents of each Borrower as in effect on such date of certification.

          (iii)  SECRETARY'S CERTIFICATE; BY-LAWS; RESOLUTIONS.  The Bank shall
     have received from each of the Borrowers a Secretary's certificate, dated
     as of the Closing Date, signed by the Secretary of each such Borrower,

     completeness of:  (A) the articles of incorporation and good standing 
     certificate of such Borrower; (B) a true copy of the by-laws of such 
     Borrower; (C) a copy of the resolutions adopted by the board of 
     directors of such Borrower authorizing the transactions described 
     herein; (D) the name and specimen signature of each individual who

     each of the Loan Documents to which the Borrower is or is to become a 
     party and to give notices and to take other action on behalf of such 
     Borrower under the Loan Documents.  All action on the part of the 
     Borrowers necessary for the valid execution, delivery and performance 
     by the Borrowers of this Agreement and the other Loan Documents to 
     which the Borrowers are or are to become parties shall have been duly 
     and effectively taken, and evidence thereof satisfactory to the Bank 
     shall have been provided to the Bank.
     
          (iv)   VALIDITY OF LIENS.  The Security Documents shall be 
     effective to create in favor of the Bank a legal, valid and enforceable 
     first (except for Permitted Liens entitled to priority under applicable 
     law) security interest in the Collateral (as defined therein).  All 
     filings, recordings, deliveries of instruments and other actions 
     necessary or desirable in the opinion of the Bank to protect and 
     preserve such security interests shall have been duly effected.  The 
     Bank shall have received evidence thereof in form and substance 
     satisfactory to the Bank.  With respect to Collateral which is 
     evidenced by certificates of title, the Bank shall have received 
     certificates of title to all, or such lesser number acceptable to the 
     Bank, of such certificated equipment owned by the Borrowers, with any 
     third-party liens evidenced on such certificates of title duly released 
     by the lien holders identified on such certificates of title, and shall 
     have also received such other documentation and signatures as are 
     required to have the lien of the Banks created pursuant to the Security 
     Documents recorded thereon.  Notwithstanding anything to the contrary 
     in this subsection (iv), Borrowers will use their best efforts before 
     and after the Closing Date to obtain from each landlord from which the 
     Bank has not already received such instrument a Landlord's Consent and 
     Waiver of Lien as requested by the Bank, but the receipt of such 
     instrument with regard to each landlord shall not be a condition 
     precedent to the making of the Loans.
     
          (v)    INSURANCE. The Bank shall have received insurance binders 
     or certificates of insurance coverage with respect to all insurance

     such matters and in form and substance as are satisfactory to 
     the Bank.

25
<PAGE>
     
          (vii)  REPRESENTATIONS TRUE; NO EVENT OF DEFAULT.  Each of the 
     representations and warranties of the Borrowers contained in this 
     Agreement, the other Loan Documents or in any document or instrument 
     delivered pursuant to or in connection with this Agreement shall be 
     true as of the date of such Loan and no Default or Event of Default 
     shall have occurred and be continuing.  The Bank shall have received a 
     Closing Certificate to such effect signed by an authorized officer of 
     each Borrower.
     
          (viii) NO LEGAL IMPEDIMENT.  No change shall have occurred in any 
     law or regulations thereunder or interpretations thereof that in the 
     reasonable opinion of the Bank would make it illegal for the Bank to 
     make such Loan.
     
          (ix)   SOLVENCY.  The Bank shall have received a certificate as to 
     the solvency of each Borrower other than Nordata, Inc. in substantially 
     the form of EXHIBIT G hereto signed by an officer of each Borrower.
     
          (x)    SOFTWARE REVIEW.  The Bank shall have received a copy of a 
     written assessment provided by a third-party software consultant to 
     Borrowers covering, with regard to Borrowers' software and its 
     architecture, the processes and procedures used by Borrowers in its 
     development, its functionality, its compliance with Microsoft 
     standards, its documentation and commentary on qualitative factors in 
     the development process of such software, together with any commentary 
     such consultant may provide regarding the development of the Medallion 
     software and any initial feedback from Beta version users of such 
     Medallion software.
     
          (xi)   YEAR 2000 REVIEW.  Each Borrower and Subsidiary has taken, 
     or will take, in a timely manner, and in all events on or before 
     December 31, 1999, all necessary action to assure that each such 
     Borrower or Subsidiary will be Year 2000 Compliant.  As used in this 
     Agreement, "Year 2000 Compliant" shall mean, in regard to any entity, 
     that all software, hardware, firmware, equipment, goods or systems 
     utilized by or material to the business operations or financial 
     condition of such entity, will properly perform date-sensitive 
     functions before, during and after the year 2000.  The Bank shall have 
     received, with respect to Eltrax, Nordata and Four Corners, an 
     internally-prepared assessment of Year-2000 risk and a compliance plan, 
     which addresses hardware, software and telecom inventories, customer 
     and vendor communication, vendor preparedness, status of new hardware 
     and software for Borrowers' own critical systems including financial 
     and managerial accounting systems and internal communications, together 
     with a budget and timeline for the installation of any new software or 
     hardware to be acquired in respect of any Year-2000 problem. The Bank 
     shall have received, with respect to Encore, GSS and Five Star, an 
     assessment of Year-2000 risk and a compliance plan prepared by a 
     third-party consultant, which assesses each proprietary software 
     product, associated software tools whether owned or licensed by Encore 
     and their respective hardware platforms and is accompanied by evidence 
     that each such product has been thoroughly tested and found to work 
     properly in an environment which accurately simulates a post-December 
     31, 1999 environment.


26
<PAGE>

          (xii)  OTHER DOCUMENTS.  The Bank shall have received all other 
     documents and assurances which it requires or which it may reasonably 
     request in connection with the transactions contemplated by this 
     Agreement.
     
          (xiii) PROCEEDINGS AND DOCUMENTS.  All proceedings in connection 
     with the transactions contemplated by this Agreement, the other Loan 
     Documents and all other documents incident thereto shall be 
     satisfactory in substance and in form to the Bank and its counsel, and 
     the Bank and such counsel shall have received all information and such 
     counterpart originals or certified or other copies of such documents as 
     the Bank may reasonably request.
     
     (b)  CONDITIONS OF MAKING SUBSEQUENT REVOLVING CREDIT LOANS. The 
obligation of the Bank to make any Revolving Credit Loan on any Drawdown Date 
subsequent to the Closing Date is subject to the satisfaction of the 
following conditions precedent on or before the date of each such subsequent 
Loan:

          (i)    REPRESENTATIONS AND WARRANTIES. Each of the representations and
     warranties of the Borrower contained in this Agreement, the other Loan
     Documents or in any document or instrument delivered pursuant to or in
     connection with this Agreement shall be true as of the date as of which
     they were made and shall also be true at and as of the time of the making
     of such Loan, with the same effect as if made at and as of that time
     (except to the extent of changes resulting from transactions contemplated
     or permitted by this Agreement and the other Loan Documents and changes
     occurring in the ordinary course of business that singly or in the
     aggregate are not materially adverse, and except to the extent that such
     representations and warranties relate expressly to an earlier date).

          (ii)   PERFORMANCE.  The Borrowers shall have performed and complied
     with all terms and conditions herein required to be performed or complied
     with by it prior to or on such Drawdown Date and on such Drawdown Date no
     Default or Event of Default shall have occurred or be continuing and there
     shall exist no condition which would, with either or both the giving of
     notice or the lapse of time, result in an Event of Default upon
     consummation of the subsequent Loan to be made on such Drawdown Date.

Each request by the Borrowers for a Revolving Credit Loan shall constitute
certification by the Borrowers that the conditions specified in this Section
5(b) have been or will be duly satisfied on the date of such loan advance.

     6.   COVENANTS OF THE BORROWERS.  Each of the Borrowers covenants and 
agrees with the Bank as follows:

     (a)  MAINTENANCE OF EXISTENCE. The Borrowers will, and will cause each 
of their subsidiaries to, maintain their existence and comply with all 
applicable statutes, rules and regulations and to remain duly qualified as a 
foreign corporation, licensed and in good standing in each jurisdiction where 
such qualification or licensing is required by the nature of its business, 


27
<PAGE>

the character and location of its property, business or customers, or the 
ownership or leasing of its property, except where such noncompliance or 
failure to so qualify would not have a Material Adverse Effect, and the 
Borrowers will, and will cause each of their Subsidiaries to, maintain their 
properties in good operating condition, and continue to conduct their 
business as presently conducted.  Notwithstanding anything to the contrary in 
the foregoing paragraph, Eltrax may merge entirely into itself or any 
Subsidiary any of its Subsidiaries, upon prior written notice to the Bank, 
provided, however, that the Accounts of any such Subsidiary which were not 
already Eligible Accounts before such merger shall not be deemed Eligible 
Accounts, and the Inventory of such Subsidiary which was not already Eligible 
Inventory before such merger shall not be deemed Eligible Inventory, unless 
consented to in writing by the Bank.

     (b)  TAXES AND OTHER LIENS.  The Borrowers will, and will cause each of 
their Subsidiaries to, pay when due all taxes, assessments, governmental 
charges or levies, or claims for labor, supplies, rent and other obligations 
made against it which, if unpaid, might become a lien or charge against the 
Borrowers or such Subsidiaries or on their property, except liabilities being 
contested in good faith and by proper proceedings, as to which adequate 
reserves with respect thereto are maintained on the books of the Borrowers or 
their Subsidiaries, as the case may be, in accordance with GAAP.

     (c)  INSURANCE.  The Borrowers will, and will cause each of their 
Subsidiaries to, maintain with financially sound and reputable insurance 
companies, (i) insurance on its properties, (ii) public liability insurance 
against claims for personal injury or death as a result of the use of any 
products sold by it and (iii) insurance coverage against other business 
risks, in each case, in at least such amounts and against at least such risks 
(and with such risk retention) as are usually and prudently insured against 
in the same general area by companies of established repute engaged in the 
same or a similar business; and the Borrowers will furnish to the Bank, upon 
its written request, full information as to the insurance so carried.  All 
such insurance shall name the Bank as a loss payee and as an additional 
insured as its interests may appear and shall provide that no termination, 
cancellation or material reduction in the amount of coverage or a material 
modification of the extent of coverage shall be effective until at least 30 
days after receipt by the Bank of notice thereof.

     (d)  FINANCIAL STATEMENTS, ETC.  The Borrowers will furnish to the Bank:

          (i)    Within twenty-five (25) days after the end of each calendar
     month (including the last month of the fiscal year), (A) the unaudited

          personnel of such Borrower or any Subsidiary thereof or other
          employees having responsibility for the compliance by such Borrower or
          any Subsidiary thereof with Environmental Laws, without any
          independent investigation, which does cause, or could cause, such
          property, or any part thereof, to contain Hazardous Substances in

     (g)  ERISA INFORMATION.

          (i)    The Borrowers will not permit any pension plan maintained by
     any Borrower or  by any member of a "controlled group" (ERISA 210(c) or

     "reportable event" (ERISA 4043) within 30 days after its occurrence or as
     to any reportable event as to which the 30-day notice period requirement of
     Section 4043(b) of Title IV of ERISA has been waived by the PBGC, within 30
     days of such time as any Borrower is requested to notify the PBGC of such
     reportable event; (c) incur any "accumulated funding deficiency" (ERISA
     302); (d) terminate its existence at any time in a manner which could

     reportable event under Section 4043(b) of Title IV of ERISA with 
     respect to any employee pension or other benefit plan of such Borrower 
     or any Subsidiary thereof subject to such Title has occurred, or that 
     the PBGC or such Borrower or any Subsidiary thereof has instituted or 
     will institute proceedings under such Title to terminate such Plan, 
     deliver to the Bank a certificate of the chief financial officer of 
     such Borrower setting forth details as to such reportable event and the 
     action which such Borrower or such Subsidiary proposes to take with 
     respect thereto, together with a copy of any notice of such reportable 
     event which may be required to be filed with the PBGC, or any notice 
     delivered by the PBGC evidencing its intent to institute such 
     proceedings, or any notice to the PBGC that the Plan is to be 
     terminated, as the case may be.  Notwithstanding the foregoing 
     sentence, no Borrower shall have any obligation to notify the Bank as 
     described above as to any reportable event as to which the thirty (30)

     by the PBGC, until such time as such Borrower or a Subsidiary thereof 
     is required to notify the PBGC of such reportable event.  For purposes 
     of this covenant, the Borrower shall be deemed to have all knowledge or 
     knowledge of all facts attributable to the plan administrator under 
     such Title IV, but only to the extent, in the case of any multiemployer 
     plan, it can reasonably obtain such information.  In addition, upon 
     request of the Bank, the Borrower shall furnish the Bank (or cause, or 
     in the case of a multiemployer plan, exert their best efforts to cause, 
     the plan administrator to furnish the Bank) with the Annual Report for 
     each plan covered by such Title IV and filed with the Internal Revenue 
     Service.

     and delivery of or the consummation or administration of any of the 
     transactions contemplated by, or any amendment, supplement or

     directors and hold the Bank and its officers and directors harmless 
     from and against any and all liabilities, losses, damages, costs and 
     expenses of any kind (including, without limitation, the reasonable 
     fees and disbursements of counsel for the Bank in connection with any 
     investigative, administrative or judicial proceeding, whether or not 
     the Bank shall be designated a party thereto) which may be incurred by 
     the Bank, relating to or arising out of this Agreement or any other 
     Loan Document, or the existence of any Hazardous Substance on, in, or 
     under any property owned, leased or occupied by the Borrowers or any of 
     its Subsidiaries, or any violation of any applicable Environmental Laws 
     for which any Borrower or any of their subsidiaries has any liability 
     or which occurs upon any property owned, leased or occupied by any 
     Borrower or any of their subsidiaries, or the imposition of any Lien 
     under any Environmental Laws, provided that the Bank shall not have the 
     right to be indemnified hereunder for its own gross negligence or 
     willful misconduct as determined by a court of competent jurisdiction.
     
          (iii)  The agreements in this Section 6(i) shall survive

joint enterprise or other joint arrangement with, any Affiliate of the 
Borrowers unless such transaction is otherwise permitted under this 
Agreement, is in the ordinary course of the Borrowers' or their Subsidiary's

that the Obligations will be paid strictly in accordance with the terms 
thereof, regardless of any law, regulation or order now or hereafter in 
effect in any jurisdiction affecting any of such terms of the rights of the 
Bank with respect thereto.  The liability of each Borrower with regard to the 
Obligations shall be absolute and unconditional irrespective of:

          (i)    any other Borrower's lack of authorization, execution, 
     validity or enforceability of this Agreement, any prior amendment 
     hereof and any further amendment hereof (with regard to such 
     Obligations), or any other obligation, agreement or instrument relating 
     thereto (it being agreed by each Borrower that the Obligations shall 
     not be discharged prior to the final and complete satisfaction of all 
     of the Obligations) or any failure to obtain any necessary governmental 
     consent or approval or necessary third party consents or approvals;
     
          (ii)   the Bank's exercise or enforcement of, or failure or delay

     enforce against any Borrower any of the Obligations, or (ii) any change 
     in the time, manner or place of payment of, or in any other term of, 
     all or any of the Obligations or any other amendment or waiver of or 
     any consent to departure from this Agreement, as 


40
<PAGE>

     amended, or any other Loan Document (with regard to such Obligations) 
     or any other agreement or instrument governing or evidencing any of the 
     Obligations;
     
          (iii)  any exchange, release or non-perfection of any collateral, 
     or any release or amendment or waiver of or consent to departure from 
     any other guaranty, for all or any of the Obligations;
     
          (iv)   any change in ownership of any Borrower;
     
          (v)    any acceptance of any partial payment(s) from any Borrower;

          (vi)   any insolvency, bankruptcy, reorganization, arrangement, 
     adjustment, composition, assignment for the benefit of creditors, 
     appointment of a receiver or trustee for all or any part of any 
     Borrower's assets;
     
          (vii)  any cancellation, renunciation or surrender of any pledge, 
     guaranty or any debt instrument evidencing the Obligations;
     
          (viii) the Bank's vote, claim, distribution, election, acceptance, 
     action or inaction in any bankruptcy or reorganization case related to 
     the Obligations; or
     
          (ix)   any other action or circumstance, other than payment, which 
     might otherwise constitute a defense available to, or a discharge of, 
     any Borrower in respect of the Obligations (other than the defense of 
     payment in full in cash).

No invalidity, irregularity or unenforceability by reason of any bankruptcy 
or similar law, or any law or order of any government or agency thereof 
purporting to reduce, amend or otherwise affect any liability of any 
Borrower, and no defect in or insufficiency or want of powers of any Borrower 
or irregular or improperly recorded exercise thereof, shall impair, affect, 
be a defense to or claim against such Borrower.  Each Borrower hereby waives 
promptness, diligence, protest, notice of protest, all suretyship defenses, 
notice of acceptance and any other notice with respect to any of the 
Obligations and any requirement that the Bank secure, perfect or protect any 
security interest or lien on any property subject thereto or exhaust any 
right to take any action against any Borrower and any other person or any 
collateral.  Each Borrower also irrevocably waives, to the fullest extent 
permitted by law, all defenses which at any time may be available to it in 
respect of the Obligations by virtue of any statute of limitations, 
valuation, stay, moratorium law or similar law now or hereinafter in effect 
and all suretyship defenses generally.

     11.  SUCCESSORS AND ASSIGNS.  The provisions of this Agreement shall be 
binding upon and inure to the benefit of the parties hereto and their 
respective successors and assigns, except that the Borrowers may not assign 
or otherwise transfer any of their rights under this Agreement without the 
prior written consent of the Bank.  All covenants, agreements and obligations 
of the Borrowers under this Agreement and each other Loan Document are joint 
and several in all respects.

     12.  MISCELLANEOUS.  Any communication to be made hereunder shall (a) be 
made in writing, but unless otherwise stated, may be made by telex, facsimile 
transmission or letter, and (b) be made or delivered to the address of the 
party receiving notice which is identified with its signature below (unless 
such party has by three (3) days' written notice specified another address), 
and shall be deemed made or delivered, when dispatched, left at that address, 
or three (3) days after being mailed, postage prepaid, to such address.  This 
Agreement may not be amended or waived except by a written instrument signed 
by the Borrowers and the Bank, and any such amendment or waiver shall be 
effective only for the specific purpose given.  No failure or delay by the 
Bank to exercise any right hereunder shall operate as a waiver thereof, nor 
shall any single or partial exercise of any right, power or privilege 
preclude any other right, power or privilege.  The provisions of this 
Agreement are severable and if any one provision hereof shall be held invalid 
or unenforceable in whole or in part in any jurisdiction, such invalidity or 
unenforceability shall affect only such provision in such jurisdiction.  This 
Agreement, together with all Exhibits and Schedules hereto, expresses the 
entire understanding of the parties with respect to the transactions 
contemplated hereby.  This Agreement and any amendment hereby may be executed 
in several counterparts, each of which shall be an original, and all of which 
shall constitute one agreement.  In proving this Agreement, it shall not be 
necessary to produce more than one such counterpart executed by the party to 
be charged.  THIS AGREEMENT AND THE NOTES ARE CONTRACTS UNDER THE LAWS OF THE 
COMMONWEALTH OF MASSACHUSETTS AND SHALL BE CONSTRUED IN ACCORDANCE THEREWITH 
AND GOVERNED THEREBY (OTHER THAN THE CONFLICTS OF LAW PROVISIONS).  THE 
BORROWERS AGREE THAT ANY SUIT FOR THE ENFORCEMENT OF ANY OF THE LOAN 
DOCUMENTS MAY BE BROUGHT IN THE COURTS OF THE COMMONWEALTH OF MASSACHUSETTS 
OR ANY FEDERAL COURT SITTING THEREIN.  THE BORROWERS, AS AN INDUCEMENT TO THE 
BANK TO ENTER INTO THIS AGREEMENT, HEREBY WAIVE THEIR RIGHT TO A JURY TRIAL 
WITH RESPECT TO ANY ACTION ARISING IN CONNECTION WITH ANY LOAN DOCUMENT.

     financially sound and reputable insurers insurance with respect to its
     properties and business against such casualties and contingencies as shall
     be in accordance with general practices of businesses engaged in similar
     activities in similar geographic areas.  All such insurance shall be in
     such minimum amounts that the Company will not be deemed a co-insurer under
     applicable insurance laws, regulations and policies and otherwise shall be
     in such amounts, contain such terms, be in such forms and be for such
     periods as may be reasonably satisfactory to the Bank.  In addition, all
     such insurance shall be payable to the Bank as loss payee under a
     "standard" or "New York" loss payee clause.  Without limiting the
     foregoing, the Company will (a) keep all of its physical property insured
     with casualty or physical hazard insurance on an "all risks" basis, with
     broad form flood and earthquake coverages and electronic data processing
     coverage, with a full replacement cost endorsement and an "agreed amount"
     clause in an amount equal to 100% of the full replacement cost of such
     property, (b) maintain all such workers' compensation or similar insurance

     marine insurance; and product liability insurance.

     respect of any casualty loss of any of the Collateral shall, subject to the
     rights, if any, of other parties with a prior interest in the property
     covered thereby, (a) so long as no Default or Event of Default has occurred
     and is continuing and to the extent that the amount of such proceeds is
     less than $10,000, be disbursed to the Company for direct application by
     the Company solely to the repair or replacement of the Company's property
     so damaged or destroyed and (b) in all other circumstances, be held by the
     Bank as cash collateral for, or 

                                    54
<PAGE>

                                
     applied to repay, the Obligations.  The Bank may, at its sole option, 
     disburse from time to time all or any part of such proceeds so held as 
     cash collateral, upon such terms and conditions as the Bank may reasonably
     prescribe, for direct application by the Company solely to the repair or 
     replacement of the Company's property so damaged or destroyed, or the 
     Bank may apply all or any part of such proceeds to the Obligations.

          7.3.   NOTICE OF CANCELLATION, ETC.  All policies of insurance shall
     provide for at least thirty (30) days' prior written cancellation notice to
     the Bank.  In the event of failure by the Company to provide and maintain
     insurance as herein provided, the Bank may, at its option, provide such
     insurance and charge the amount thereof to the Company.  The Company shall
     furnish the Bank with certificates of insurance and policies evidencing
     compliance with the foregoing insurance provision.

     8.   MAINTENANCE OF COLLATERAL; COMPLIANCE WITH LAW.  The Company will keep
the Collateral in good order and repair and will not use the same in material
violation of law or any policy of insurance thereon.  The Bank, or its designee,
may inspect the Collateral at any reasonable time, wherever located.  The
Company will pay promptly when due all taxes, assessments, governmental charges
and levies upon the Collateral or incurred in connection with the use or
operation of such Collateral or incurred in connection with this Agreement.  The
Company has at all times operated, and the Company will continue to operate, its
business in compliance with all applicable provisions of the federal Fair Labor
Standards Act, as amended, and with all applicable provisions of federal, state
and local statutes and ordinances dealing with the control, shipment, storage or
disposal of hazardous materials or substances.  Within ten (10) days of the date
hereof, and thereafter from time to time upon request of the Bank (but no more
often than quarterly if no Event of Default has occurred and is continuing), the
Company will provide the Bank with a schedule identifying all customer locations
at which vending machines or other Collateral is located (which Schedule will
include the name and address of such customers and the vending machines and
other Collateral located thereat).

     9.   COLLATERAL PROTECTION EXPENSES; PRESERVATION OF COLLATERAL.

          9.1.   EXPENSES INCURRED BY THE BANK.  In its discretion, the Bank may
     discharge taxes and other encumbrances at any time levied or placed on any
     of the Collateral, make repairs thereto and pay any necessary filing fees.
     The Company agrees to reimburse the Bank on demand for any and all
     expenditures so made.  The Bank shall have no obligation to the Company to
     make any such expenditures, nor shall the making thereof relieve the
     Company of any default.

          9.2.   BANK'S OBLIGATIONS AND DUTIES.  Anything herein to the contrary
     notwithstanding, the Company shall remain liable under each contract or
     agreement comprised in the Collateral to be observed or performed by the
     Company thereunder.  The Bank shall not have any obligation or liability
     under any such contract or agreement by reason of or arising out of this
     Agreement or the receipt by the Bank of any payment relating to any of the
     Collateral, nor shall the Bank be obligated in any manner to perform 

                                    55
<PAGE>

     any of the obligations of the Company under or pursuant to any such 
     contract or agreement, to make inquiry as to the nature or sufficiency of 
     any payment received by the Bank in respect of the Collateral or as to the
     sufficiency of any performance by any party under any such contract or 
     agreement, to present or file any claim, to take any action to enforce any 
     performance or to collect the payment of any amounts which may have been 
     assigned to the Bank or to which the Bank may be entitled at any time or 
     times.  The Bank's sole duty with respect to the custody, safe keeping and 
     physical preservation of the Collateral in its possession, under 9-207 of 
     the Uniform Commercial Code of the Commonwealth of Massachusetts or 
     otherwise, shall be to deal with such Collateral in the same manner as the 
     Bank deals with similar property for its own account.

     10.  SECURITIES AND DEPOSITS.  The Bank may at any time, at its option,
transfer to itself or any nominee any securities constituting Collateral.  After
and during the continuance of an Event of Default, the Bank may, at its option,
(i) receive any income on any securities constituting Collateral and hold such
income as additional Collateral or apply it to the Obligations and (ii) demand,
sue for, collect, or make any settlement or compromise which it deems desirable
with respect to the Collateral.  Regardless of the adequacy of Collateral or any
other security for the Obligations, any deposits or other sums at any time
credited by or due from the Bank to the Company may at any time be applied to or
set off against any of the Obligations.

     11.  NOTIFICATION TO ACCOUNT DEBTORS AND OTHER OBLIGORS.  At any time after
an Event of Default has occurred and is continuing,

          (a)    The Bank may notify account debtors on accounts, chattel paper
     and general intangibles of the Company and obligors on instruments for
     which the Company is an obligee that payment thereof is to be made directly
     to the Bank or such other address as may be specified by the Bank, and may

     constitutes and appoints the Bank and any officer or agent thereof, with
     full power of substitution, as its true and lawful attorneys-in-fact with

                 (a)  Upon the occurrence and during the continuance of an Event
          of Default, generally to sell, transfer, pledge, make any agreement
          with respect to or otherwise deal with any of the Collateral in such
          manner as is consistent with the Uniform Commercial Code of the
          Commonwealth of Massachusetts and as fully and completely as though
          the Bank were the absolute owner thereof for all purposes, and to do
          at the Company's expense, at any time, or from time to time, all acts
          and things which the Bank deems necessary to protect, preserve or
          realize upon the Collateral and the Bank's security interest therein,
          in order to effect the intent of this Agreement, all as fully and
          effectively as the Company might do, including, without limitation,
          (i) the filing and prosecuting of registration and transfer
          applications with the appropriate federal or local agencies or
          authorities with respect to trademarks, copyrights and patentable
          inventions and processes, (ii) upon written notice to the Company, the
          exercise of voting rights with respect to voting securities, which
          rights may be exercised, if the Bank so elects, with a view to causing
          the liquidation in a commercially reasonable manner of assets of the
          issuer of any such securities and (iii) the execution, delivery and
          recording, in connection with any sale or other disposition of any
          Collateral, of the endorsements, assignments or other instruments of
          conveyance or transfer with respect to such Collateral; and

                 (b)  To file such financing statements with respect hereto,

          statements and amendments thereto and continuation statements which
          may require the Company's signature.

          13.2.  RATIFICATION BY COMPANY.  To the extent permitted by law, the
     Company hereby ratifies all that said attorneys shall lawfully do or cause
     to be done by virtue hereof This power of attorney is a power coupled with
     an interest and shall be irrevocable.

          13.3.  NO DUTY ON BANK.  The powers conferred on the Bank hereunder
     are solely to protect its interests in the Collateral and shall not impose
     any duty upon it to exercise any such powers.  The Bank shall be
     accountable only for the amounts that it actually receives as a result of
     the exercise of such powers and neither it nor any of its officers,
     directors, employees or agents shall be responsible to the Company for any
     act or failure to act, except for the Bank's own gross negligence or
     willful misconduct.

     14.  REMEDIES.  If an Event of Default shall have occurred and be
continuing, the Bank may, without notice to or demand upon the Company, declare
this Agreement to be in default, and the Bank shall thereafter have in any
jurisdiction in which enforcement hereof is sought, in addition to all other
rights and remedies, the rights and remedies of a secured party under the
Uniform Commercial Code, including, without limitation, the right to take
possession 

                                    59
<PAGE>

of the Collateral, and for that purpose the Bank may, so far as the
Company can give authority therefor, enter upon any premises on which the
Collateral may be situated and remove the same therefrom.  The Bank may in its
discretion require the Company to assemble all or any part of the Collateral at
such location or locations within the state(s) of the Company's principal
office(s) or at such other locations as the Bank may designate.  Unless the
Collateral is perishable or threatens to decline speedily in value or is of a
type customarily sold on a recognized market, the Bank shall give to the Company
at least five Business Days' prior written notice of the time and place of any
public sale of Collateral or of the time after which any private sale or any
other intended disposition is to be made.  The Company hereby acknowledges that
five business Days' prior written notice of such sale or sales shall be
reasonable notice.  If any of the Collateral which constitutes securities is not
registered under applicable state and federal securities laws, the Bank shall
not be obligated to register such Collateral and may, in effecting any sale
thereof, impose such conditions and limitations on the sale as the Bank deems
appropriate to comply with applicable securities laws, including but not limited
to requiring an investment representation agreement from any purchaser thereof
and imposing restrictions as to the financial sophistication and ability of any
person permitted to bid or purchase at any such sale, and such actions by the
Bank shall be deemed commercially reasonable.  In addition, the Company waives
any and all rights that it may have to a judicial hearing in advance of the
enforcement of any of the Bank's rights hereunder, including, without
limitation, its right following an Event of Default to take immediate possession
of the Collateral and to exercise its rights with respect thereto.  To the
extent that any of the Obligations are to be paid or performed by a person other
than the Company, the Company waives and agrees not to assert any rights or
privileges which it may have under 9-112 of the Uniform Commercial Code of the
Commonwealth of Massachusetts.

     15.  NO WAIVER, ETC.  The Company waives demand, notice, protest, notice of
acceptance of this Agreement, notice of loans made, credit extended, Collateral
received or delivered or other action taken in reliance hereon and all other
demands and notices of any description.  With respect to both the Obligations
and the Collateral, the Company assents to any extension or postponement of the
time of payment or any other indulgence, to any substitution, exchange or
release of or failure to perfect any security interest in any Collateral, to the
addition or release of any party or person primarily or secondarily liable, to
the acceptance of partial payment thereon and the settlement, compromising or
adjusting of any thereof, all in such manner and at such time or times as the
Bank may deem advisable.  The Bank shall have no duty as to the collection or
protection of the Collateral or any income thereon, nor as to the preservation
of rights against prior parties, nor as to the preservation of any rights
pertaining thereto beyond the safe custody thereof as set forth in 9.2 hereof.
The Bank shall not be deemed to have waived any of its rights upon or under the
Obligations or the Collateral unless such waiver shall be in writing and signed
by the Bank.  No delay or omission on the part of the Bank in exercising any
right shall operate as a waiver of such right or any other right.  A waiver on
any one occasion shall not be construed as a bar to or waiver of any right on
any future occasion.  All rights and remedies of the Bank with respect to the
Obligations or the Collateral, whether evidenced hereby or by any other
instrument or papers, shall be cumulative and may be exercised singularly,
alternatively, successively or concurrently at such time or at such times as the
Bank deems expedient.

                                    60
<PAGE>

     16.  MARSHALLING.  The Bank shall not be required to marshal any present or
future collateral security (including but not limited to this Agreement and the
Collateral) for, or other assurances of payment of, the Obligations or any of
them or to resort to such collateral security or other assurances of payment in
any particular order, and all of its rights hereunder and in respect of such
collateral security and other assurances of payment shall be cumulative and in
addition to all other rights, however existing or arising.  To the extent that
it lawfully may, the Company hereby agrees that it will not invoke any law
relating to the marshalling of collateral which might cause delay in or impede
the enforcement of the Bank's rights under this Agreement or under any other
instrument creating or evidencing any of the Obligations or under which any of
the Obligations is outstanding or by which any of the Obligations is secured or
payment thereof is otherwise assured, and, to the extent that it lawfully may,
the Company hereby irrevocably waives the benefits of all such laws.

     17.  PROCEEDS OF DISPOSITIONS, EXPENSES.  The Company shall pay to the Bank
on demand any and all expenses, including reasonable attorneys' fees and
disbursements, incurred or paid by the Bank in protecting, preserving or
enforcing the Bank's rights under or in respect of any of the Obligations or any
of the Collateral.  After deducting all of said expenses, the residue of any
proceeds of collection or sale of the Obligations or Collateral shall, to the
extent actually received in cash, be applied to the payment of the Obligations
in such order or preference as the Bank may determine, proper allowance and
provision being made for any Obligations not then due.  Upon the final payment
and satisfaction in full of all of the Obligations and after making any payments
required by Section 9-504(l)(c) of the Uniform Commercial Code of the
Commonwealth of Massachusetts, any excess shall be returned to the Company, and
the Company shall remain liable for any deficiency in the payment of the
Obligations.

     18.  OVERDUE AMOUNTS.  Until paid, all amounts due and payable by the
Company hereunder shall be a debt secured by the Collateral and shall bear,
whether before or after judgment, interest at the rate of interest for overdue
principal set forth in the Credit Agreement.

     19.  GOVERNING LAW, CONSENT TO JURISDICTION.  THIS AGREEMENT IS INTENDED
TO.  TAKE EFFECT AS A SEALED INSTRUMENT AND SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS.  The Company
agrees that any suit for the enforcement of this Agreement may be brought in the
courts of the Commonwealth of Massachusetts or any federal court sitting therein
and consents to the non-exclusive jurisdiction of such court and to service-vice
of process in any such suit being made upon the Company by mail at the address
specified in the Credit Agreement.  The Company hereby waives any objection that
it may now or hereafter have to the venue of any such suit or any such court or
that such suit is brought in an inconvenient court.

     20.  WAIVER OF JURY TRIAL.  THE COMPANY WAIVES ITS RIGHT TO A JURY TRIAL
WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION
WITH THIS AGREEMENT, ANY RIGHTS OR OBLIGATIONS 

                                    61
<PAGE>

HEREUNDER OR THE PERFORMANCE OF ANY SUCH RIGHTS OR OBLIGATIONS.  Except as 
prohibited by law, the Company waives any right which it may have to claim or 
recover in any litigation referred to in the preceding sentence any special, 
exemplary, punitive or consequential damages or any damages other than, or in 
addition to, actual damages.  The Company (a) certifies that neither the Bank 
nor any representative, agent or attorney of the Bank has represented, 
expressly or otherwise, that the Bank would not, in the event of litigation, 
seek to enforce the foregoing waivers and (b) acknowledges that, in entering 
into the Credit Agreement and the other Loan Documents to which the Bank is a 
party, the Bank is relying upon, among other things, the waivers and 
certifications contained in this Section 20.

     21.  MISCELLANEOUS.  This Agreement and any amendment hereof may be
executed in several counterparts and by each party on a separate counter-part,
each of which when so executed and delivered shall be an original, but all of
which together shall constitute one instrument.  In proving this Agreement it
shall not be necessary to produce or account for more than one such counterpart
signed by the party against whom enforcement is sought.  The headings of each
section of this Agreement are for convenience only and shall not define or limit
the provisions thereof.  This Agreement and all rights and obligations hereunder
shall be binding upon the Company and its respective successors and assigns, and
shall inure to the benefit of the Bank and its successors and assigns.  If any
term of this Agreement shall be held to be invalid, illegal or unenforceable,
the validity of all other terms hereof shall in no way be affected thereby, and
this Agreement shall be construed and be enforceable as if such invalid, illegal
or unenforceable term had not been included herein.  The Company acknowledges
receipt of a copy of this Agreement.

     IN WITNESS WHEREOF, intending to be legally bound, the Company has caused
this Agreement to be duly executed as of the date first above written.

PREMISES: ___________________________________

TENANT:        NORDATA, INC. (D/B/A DATATECH)
               ------------------------------

     Landlord's Waiver made and entered into by the owner/landlord (the "Owner")
to, and for the benefit of, State Street Bank and Trust Company (the "Bank"),
with respect to the Premises referred to above.

     WHEREAS, the Bank and the Tenant are entering into a Credit Agreement,
promissory notes and related loan documents pursuant to which the Bank shall
make loans to and extend credit to the Tenant (all amounts now or hereafter due
and owing from the Tenant to the Bank being referred to as the "Obligations");
and

     WHEREAS, to secure the Obligations, the Tenant is granting to the Bank a
security interest in its assets, including but not limited to equipment,
furniture, trade fixtures, inventory, accounts receivable, general intangibles,
instruments, documents, books and records (hereinafter referred to as the
"Collateral"), certain of which Collateral is or shall be located in or at the
Premises; and

     WHEREAS, the Bank is unwilling to enter into the Revolving Credit Agreement
with the Tenant and make loans and advances thereunder unless the Owner executes
and delivers this Waiver;

     NOW, THEREFORE, the Owner agrees with the Bank that:

     1.   Notwithstanding anything to the contrary set forth in the Lease or
herein, the Collateral shall be and remain personal property and shall not
become, nor be deemed to be, fixtures nor attached to the Premises or the
building containing the Premises.

     2.   Owner waives and releases each and every right which Owner now has or
may hereafter have, under any applicable laws, pursuant to the Lease, or
otherwise, (a) to levy or distain upon the Collateral for the collection of rent
or any other sums due from Tenant, whether owing under the Lease or otherwise,
or (b) to claim or assert any right or title in or to, or any interests or liens
upon, the Collateral.

     3.   Owner will not interpose any objections to, and will permit, the entry
by the Bank upon the Premises for the purposes of removing and/or liquidating
the Collateral in the event of a 

<PAGE>

default by Tenant in the Obligations, provided only that the Bank restores 
any damage to the Premises caused by such entry or removal and, subject to 
the provisions of Section 4 below, the Bank completes such removal and 
liquidation within ninety (90) days of the Bank's entry into possession.  
Owner agrees that upon the Bank taking possession of the Premises, that the 
Bank's only obligation shall be as set forth in the preceding sentence, and 
that the Bank shall not be liable under or in respect of the Lease, except as 
otherwise provided in Section 4 below.

     4.   Owner represents that a true and complete copy of the Lease is
attached hereto and confirms and agrees that to the best of its knowledge there
are currently no uncured defaults on the part of the Tenant thereunder.  Owner
agrees to give the Bank a copy of any notice of default given to Tenant under
the Lease and of any notice purporting to terminate the rights of the Tenant
thereunder in the same manner and contemporaneously with any such notice to
Tenant.  Owner agrees that the Bank shall have the right, within thirty (30)
days after receipt of any such notice either (a) to enter into the Premises for
the purpose of removing and/or liquidating the Collateral in accordance with the
provisions of Section 3 hereof, or (b) with or without taking possession, to
maintain the Lease in effect by curing any default which can be cured by the
payment or expenditure of money.  Nothing herein, including the acceptance of
rent or other sums from the Bank shall be deemed an assumption of the Lease by
the Bank, nor bar the Landlord's right to collect unpaid amounts due from the
Tenant under the Lease.

     5.   The provisions hereof shall be binding upon and inure to the benefit
of the parties hereto and their respective heirs, executors, administrators,
successors and assigns and shall be governed by the laws of the Commonwealth of
Massachusetts.

in satisfaction of, an Amended and Restated Commercial Promissory Note dated 
as of July 31, 1997 issued by Eltrax Systems, Inc., Nordata, Inc. (d/b/a 
Datatech), Atlantic Network Systems, Inc., EJG Techline Incorporated and Four 
Corners Technology, Inc. to the order of the Bank in the original principal 
amount of $5,000,000.

     Interest shall be determined in all instances based upon a 360-day year 
and actual day months and shall be payable on each Interest Payment Date as 
provided in the Credit Agreement.

     Prior to the Maturity Date (whether by demand or otherwise), the 
principal amount hereof may be advanced, repaid and readvanced in accordance 
with the terms of the Credit Agreement.  The entire unpaid principal balance 
hereof and all unpaid interest hereon shall in all events be due and payable 
in full on the Maturity Date.  Upon prepayment of this Note, the Borrowers 
shall pay a Prepayment Penalty to the Bank to the extent required under the 
Credit Agreement.

     Overdue principal (whether at maturity, by reason of acceleration or 
otherwise) and, to the extent permitted by applicable law, overdue interest 
(compounded monthly and payable on demand in respect of overdue amounts) and 
fees or any other amounts payable under the Credit Agreement (including 
without limitation overadvances) due to the Borrowers' failure to pay the 
same in full shall bear interest from and including the due date thereof 
until paid, at a rate per annum equal to two percent (2%) above the interest 
rate then applicable thereto, which interest shall be compounded daily and 
payable on demand.

     All payments under this Note shall be made to the Bank at 225 Franklin 
Street, Boston, Massachusetts 02110 (or at such other place as the Bank may 
designate to the Borrower from time to time in writing) in lawful money of 
the United States of America in immediately available funds.

     This Note is the "Revolving Credit Note" referred to in and is entitled 
to the benefits of the Credit Agreement (including Schedules thereto) and all 
other instruments evidencing and/or securing the indebtedness hereunder, 
which Credit Agreement and other instruments are hereby made part of this 
Note and are deemed incorporated herein in full; but neither this reference 
to the Credit Agreement nor any provision thereof shall affect or impair the 
absolute and unconditional obligation of the Borrowers to pay the principal 
of and interest on this Note as herein provided.

     All agreements between the Borrowers and the Bank are hereby expressly 
limited so that in no contingency or event whatsoever, whether by reason of 
acceleration of maturity of the indebtedness or otherwise, shall the amount 
paid or agreed to be paid for the use or forbearance of the indebtedness 
evidenced hereby exceed the maximum amount which the Bank is permitted to 
receive under applicable law.  If, from any circumstances whatsoever, 
fulfillment of any provision hereof or of the Credit Agreement, at the time 
performance of such provision shall be due, shall involve exceeding such 
amount, then the obligation to be fulfilled shall automatically be reduced to 
the limit of such validity and if, from any circumstances the Bank should 
ever receive as interest an amount which would exceed such maximum amount, 
such amount which would be excessive interest shall be applied to the 
reduction of the principal balance evidenced hereby and not to the payment of 
interest.  As used herein, the term "applicable law" shall mean the law in 
effect as of the date hereof, provided, however, that in the event there is a 
change in the law which results in a higher permissible rate of interest, 
then this Note shall be governed by such new law as of its effective date.  
This provision shall control every other provision of all agreements between 
the Borrowers and the Bank.

     If this Note shall not be paid when due and shall be placed by the 
holder hereof in the hands of any attorney for collection, through legal 
proceedings or otherwise, the Borrowers will pay reasonable attorneys' fees 
to the holder hereof together with reasonable costs and expenses of 
collection, including, without limitation, any such reasonable attorneys' 
fees, costs and expenses relating to any proceedings with respect to the 
bankruptcy, reorganization, insolvency, readjustment of debt, dissolution or 
liquidation of the Borrowers or any party to any instrument or agreement 
securing this Note, all as provided in the Credit Agreement.

     No delay or omission on the part of the Bank or any holder hereof in 
exercising any right hereunder shall operate as a waiver of such right or of 
any other rights of the Bank or such holder, nor shall any delay, omission or 
waiver on any one occasion be deemed a bar or waiver of the same or any other 
right on any further occasion.

     The Borrowers hereby waive presentment, demand, notice, protest and all 
other demands and notices in connection with the delivery, acceptance, 
performance, default or enforcement of 

                                      67
<PAGE>

this Note, and assent to any extension or postponement of the time of payment 
or any other indulgence, to any substitution, exchange or release of 
collateral and to the addition or release of any other party or person 
primarily or secondarily liable.

     THIS NOTE AND THE OBLIGATIONS OF THE BORROWERS HEREUNDER SHALL FOR ALL 
PURPOSES BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE 
COMMONWEALTH OF MASSACHUSETTS (EXCLUDING THE LAWS APPLICABLE TO CONFLICTS OR 
CHOICE OF LAW).  THE BORROWERS AGREE THAT ANY SUIT FOR THE ENFORCEMENT OF 
THIS NOTE MAY BE BROUGHT IN THE COURTS OF THE COMMONWEALTH OF MASSACHUSETTS 
OR ANY FEDERAL COURT SITTING THEREIN AND CONSENT TO THE NONEXCLUSIVE 
JURISDICTION OF SUCH COURT AND THE SERVICE OF PROCESS IN ANY SUCH SUIT BEING 
MADE UPON THE BORROWERS BY MAIL AT THE ADDRESSES SPECIFIED IN THE CREDIT 
AGREEMENT.  THE BORROWERS HEREBY WAIVE ANY OBJECTION THAT THEY MAY NOW OR 
HEREAFTER HAVE TO THE VENUE OF ANY SUCH SUIT OR ANY SUCH COURT OR THAT SUCH 
SUIT IS BROUGHT IN AN INCONVENIENT COURT.

     This Note shall be deemed to take effect as a sealed instrument under 
the laws of the Commonwealth of Massachusetts.

     IN WITNESS WHEREOF, each of the undersigned have caused this Note to be 
signed in its respective corporate name and its respective corporate seal to 
be impressed hereon by a duly authorized officer as of the day and year first 
above written.

liabilities mature, and (d) such Person is not engaged, and is not about to
