would materially adversely effect the Acquired Assets and the Acquired Business,
the ability of EHGI to sell, transfer, convey and assign the Acquired Assets and
the Acquired Business to the Purchaser or result in the assumption of any
Liabilities by the Purchaser other than the Assumed Liabilities.

         2.2      Manner of Payment. Payment of the Consideration by the

                        ACQUISITION OF FOREIGN OPERATIONS

         3.1      Agreement to Acquire Foreign Operations. On or prior to the
Closing Date, ESI shall, and ESI shall cause its Subsidiaries to, sell,

(Eltrax Systems Scandinavia AS), Singapore (Eltrax Systems Pte. Ltd.),
Switzerland (Eltrax Holdings, AG and Eltrax AG) and the United Kingdom (Eltrax

10,000. This Transaction and the other transactions involving the Affiliated
Sellers (the "Related Transactions") are all interrelated transactions. ESI and
the Purchaser contemplate that in connection with the Related Transactions, the
purchaser may be a wholly-owned (direct or indirect) Subsidiary of the Purchaser
and the seller will be a wholly-owned (direct or indirect) Subsidiary of ESI. In
that event, Purchaser will be jointly and severally liable for the obligations
of its wholly-owned Subsidiary and ESI will be jointly and severally liable for
the obligations of its Subsidiary with respect to the Related Transactions. The
terms of the definitive agreements for the Related Transactions will be, to the
extent possible, identical to those set forth in this Agreement, giving due and
reasonable regard to the nuances of the laws of the various countries in which
the Affiliated Sellers are located. The Purchaser and ESI shall proceed in good
faith to finalize the purchase agreements for the Related Transactions as soon
as is practicable, consistent with the foregoing. The Closing of this
Transaction, and the closings of the Related Transactions, shall be dependent on
one another, such that none of the transactions shall close unless all of them
close, notwithstanding any other provision of this Agreement or of the purchase
agreements for the Related Transactions to the contrary. ESI and the Purchaser
hereby agree that notwithstanding any provision of any agreement relative to the
Related Transactions (including, without limitation, any "integration" clause
included in any such agreement), in the event of a conflict between a provision
of this Agreement and any provision of any agreement relative to the Related
Transactions, the provisions of this Agreement shall control.

                                       9
<PAGE>   10

identified in Section 5.3.5 of the Acquired Business Disclosure Document,
constitute grounds for the loss or suspension of any permits, licenses, or other
authorizations used in the Acquired Business.

         5.4      Brokers. No broker, finder, or investment banker is entitled
to any brokerage, finder's, or other fee or commission in connection with this
Agreement or the Transaction or any related transaction based upon any
agreements, written or oral, made by or on behalf of ESI, EHGI or any of their
Subsidiaries. EHGI does not have any obligation to pay finder's or broker's fees
or commissions in connection with the exercise of options to renew or extend
real estate leases to which the EHGI is a party.

         5.5      Financial Statements. EHGI has heretofore delivered to the
Purchaser the following:

                  (1)      The Unaudited Financial Statements of the Acquired
         Business;

                  (2)      The Projections.

                  All of the historical financial statements contained in such
documents were prepared from the books and records oil ESI and EHGI. The
Unaudited Financial Statements were prepared in accordance with GAAP (as
qualified in Section 1.48 above). Without limiting the foregoing, as of the
Acquired Business Balance Sheet, EHGI owned each of the assets included in
preparation of the Acquired Business Balance Sheet, and the valuation of such
assets in the Acquired Business Balance Sheet is consistent with GAAP (as
qualified in Section 1.48 above), and EHGI had no Liabilities required to be
included in the Acquired Business Balance Sheet in accordance with GAAP (as
qualified in Section 1.48 above) for which the Acquired Business or any part of
the Acquired Assets is responsible or liable, other than those included in the
Acquired Business Balance Sheet, nor any Liabilities required to be included in
the Acquired Business Balance Sheet in accordance with GAAP (as qualified in
Section 1.48 above) in amounts in excess of the amounts included for them in the
Acquired Business Balance Sheet. The Purchaser acknowledges that projections of
future economic performance are necessarily unreliable and subject to the
occurrence or nonoccurrence of a variety of events, but ESI and EHGI represent
that the Projections have been prepared on the basis of assumptions that are, in
the judgment of ESI and EHGI, reasonable in all respects and are not, to the
knowledge of ESI or EHGI, contrary in any material respect to fact or to events
that have occurred or are presently in existence. From the date hereof through
the Closing Date ESI and EHGI will continue to prepare financial statements for
the Acquired Business on the same basis that they have done so in the past, will
promptly deliver the same to the Purchaser, and agree that from and after such
delivery the foregoing representations will be applicable to each financial
statement so prepared and delivered.

         5.6      Absence of Material Differences From the Acquired Business
Disclosure Document. Except as specifically disclosed in the Acquired Business
Disclosure Document in sections corresponding to the subsections below:


                                       10
<PAGE>   11

         (1)      No Undisclosed Liabilities. EHGI has no Liabilities relating
to or affecting the Acquired Business or the Acquired Assets which are not, to
the extent required by GAAP (as qualified in Section 1.48 above), adequately
reflected or reserved against on the face of the Acquired Business Balance
Sheet, except Liabilities incurred since the date of the Acquired Business
Balance Sheet in the ordinary course of business of the Acquired Business and
consistent with past practice. Without limiting the foregoing, (a) EHGI is not
in any default or in breach, in any material respect, under any contract,
license, mortgage, indenture, deed or permit held or affecting the Acquired
Business, (b) there are no leasehold improvements currently due and owing at any
of the Acquired Facilities for which the Acquired Business is or will be
responsible, and (c) there are no deferred rents due to lessors at or with
respect to any of such Acquired Facilities, and (d) the Acquired Business
Disclosure Document sets forth, as a part thereof, each Liability of or
affecting the Acquired Business or the Acquired Assets in an amount in excess of
$10,000 and each person to whom the aggregate amount of such Liabilities is in
excess of $10,000.

         (2)      No Material Adverse Change, Etc. Since the date of the
Acquired Business Balance Sheet, other than as contemplated or caused by this
Agreement, there has not been (a) any material adverse change in the business,
condition (financial or otherwise), operations, or prospects of the Acquired
Business; (b) any damage, destruction or loss, whether covered by insurance or
not, having a material adverse effect on the business, condition (financial or
otherwise), operations or prospects of the Acquired Business, or materially
adversely affecting the Acquired Assets; (c) any entry into or termination of
any material commitment, contract, agreement or transaction affecting the
Acquired Business or the Acquired Assets (including, without limitation, any
material borrowing or capital expenditure or sale or other disposition of any
material asset or assets) other than this Agreement and agreements executed in
the ordinary course of business; (d) any transfer of or right granted under any
material lease, license, agreement, patent, trademark, trade name or copyright
included among the Acquired Assets; (e) any sale or other disposition of any
asset of the Acquired Business, or any mortgage, pledge or imposition of any
lien or other encumbrance on any asset of the Acquired Business or of any
corporation included in the Acquired Assets, or any agreement relating to any of
the foregoing, other than in the ordinary course of business; or (f) any default
or breach in any material respect under any contract, license or permit held by
or for or affecting the Acquired Business. Since the date of the Acquired
Business Balance Sheet, ESI and EHGI have conducted the Acquired Business
businesses only in the ordinary and usual course, and without limiting the
foregoing, no changes have been made in (a) executive compensation levels, or
(b) the manner in which other employees of EHGI are compensated, or (c)
supplemental benefits provided to any such executives or other employees of
EHGI, or (d) inventory levels of the Acquired Business in relation to sales
levels, except, in any such case, in the ordinary course of business and, in any
event, without material adverse effect on the business, condition (financial or
otherwise), operations, or prospects of the Acquired Business.

         (3)      Taxes. ESI and EHGI have properly filed or caused to be filed
(or obtained proper extensions in respect of) all federal, state, local, and
foreign income and other tax returns, reports, and declarations that are
required by applicable law to be filed by them and that relate to or in any way
affect the Acquired Business or the Acquired Assets except for those the failure
of


                                       11
<PAGE>   12

which to file would not have an adverse effect on the Acquired Business or the
Acquired Assets, and have paid, or will pay when due all federal, state, local,
and foreign income and other taxes properly due (including any amounts deferred
as a result of an extension or otherwise) for the periods covered by such
returns, reports, and declarations.

         (4)      Litigation. (a) No material investigation or review by any
governmental entity with respect to the Acquired Business or any of the Acquired
Assets or the use thereof is, to the best of the knowledge of ESI and EHGI,
pending or threatened (other than inspections and reviews customarily made of
businesses such as the Acquired Business), nor has any governmental entity
indicated an intention to conduct the same, and (b) there is no action, suit or
proceeding pending or, to the best of the knowledge of ESI and EHGI, threatened
against or affecting the Acquired Business or the Acquired Assets at law or in
equity, or before any federal, state, municipal, or other governmental
department, commission, board, bureau, agency, or instrumentality.

         (5)      Employees, Etc. There are no collective bargaining, bonus,
profit sharing, compensation, or other plans, agreements, trusts, funds, or
arrangements maintained by EHGI for the benefit of directors, officers or
employees of EHGI and there are no employment, consulting, severance, or
indemnification arrangements, agreements, or understandings between EHGI, on the
one hand, and any current or former directors, officers or other employees of
EHGI, on the other hand. The Acquired Business Disclosure Document identifies
each person whose annualized income from EHGI, on the date of the Acquired
Business Balance Sheet, exceeded or would exceed on an annualized basis, or
whose income from EHGI in the fiscal year begun immediately thereafter is at a
rate exceeding, $50,000 per annum. EHGI is not, and following the Closing will
not be, bound by any express or implied contract or agreement to employ,
directly or as a consultant or otherwise, any person for any specific period of
time or until any specific age except as specified in agreements in writing
identified in the Acquired Business Disclosure Document or executed pursuant to
the provisions hereof.

         (6)      Compliance With Laws. The Acquired Business and each of the
Acquired Assets is in substantial compliance with all, and neither ESI nor EHGI
have received notice of any violation of any, laws or regulations applicable to
EHGI or the operations of the Acquired Business, including, without limitation,
the laws and regulations relevant to the use or utilization of premises, or with
respect to which compliance is a condition of engaging in any aspect of the
business of the Acquired Business, except to the extent the failure of which any
of the foregoing to be true would not have a material adverse effect on the
Acquired Business or the Acquired Assets. The Acquired Business has all permits,
licenses, zoning rights, and other governmental authorizations necessary to
conduct its business as presently conducted, except to the extent the failure of
the Acquired Business to have any of the foregoing would not have a material
adverse effect on the Acquired Business or the Acquired Assets. All such
permits, licenses, zoning rights, and other governmental authorizations will, as
a part and consequence of the Transactions, be transferred to the Purchaser at
the Closing.

         (7)      Ownership of Assets. EHGI has (or as of the Closing will have)
good, marketable and insurable title, or valid, effective and continuing
leasehold rights (including licenses) in the


                                       12
<PAGE>   13

case of leased or licensed property, to all real property (as to which, in the
case of owned property, such title is fee simple) and all personal property
owned or leased by it and comprising a part of the Acquired Assets or the
Acquired Business, or used by it in the conduct of the Acquired Business in such
a manner as to create the reasonable appearance or reasonable expectations that
the same is owned or leased by it; such ownership or leasehold rights are, or at
the Closing will be, free and clear of all liens, claims, encumbrances and
charges (other than those customarily held by a lessor or licensor in a lease or
license of real property), except liens for taxes not yet due and minor
imperfections of title and encumbrances, if any, which, singularly or in the
aggregate, are not substantial in amount and do not materially-detract from the
value of the property subject thereto or materially impair the use thereof, no
other person has any ownership or similar right in, or contractual or other
right to acquire any such right in, any of such assets; and such ownership or
leasehold rights will be conveyed to the Purchaser at the Closing pursuant to
the Transaction. ESI and EHGI do not know of any potential action by any party,
governmental or other, and no proceedings with respect thereto have been
instituted of which ESI or EHGI has notice, that would materially affect EHGI's
ability to use and to utilize each of such assets in the business of the
Acquired Business. Neither ESI nor EHGI has received any default notices from
any mortgagee regarding any leased properties of the Acquired Business or any
leasehold interests which comprise any part of the Acquired Assets. Section
5.6(7) of the Acquired Business Disclosure Document contains a reasonably
detailed listing, as of the date specified therein, of all Acquired Assets
including, but not limited to, (a) accounts receivable as provided in clause
(13) below, (b) miscellaneous current assets in excess of $10,000, (c) prepaid
expenses in excess of $10,000, (d) Software Products, (e) real property, and (f)
gross aggregate additions for each of the past four years by location of (i)
buildings and improvements, (ii) leasehold improvements, and (iii) automobiles
and trucks.

         (8)      Proprietary Rights, Software Products and Intellectual
Property. EHGI possesses full ownership of, or adequate and enforceable
exclusive long-term licenses or other exclusive rights to use (without payment),
all Proprietary Rights, Software Products and Intellectual Property used in the
Acquired Business or utilized in connection with the Acquired Assets, and all
such ownership, license or other rights shall be conveyed to the Purchaser at
the Closing pursuant to the Transaction; neither ESI nor EHGI has received any
notice of conflict which asserts the rights of others with respect thereto, and
EHGI has, in all material respects, performed all of the obligations required to
be performed by it, and is not in default in any material respect, under any
agreement relating to any such Proprietary Rights, Software Products and
Intellectual Property.

         (9)      Trade Names. The Acquired Business Disclosure Document
identities each trade name, fictitious business name, or other similar name
under which ESI or EHGI has conducted any part of the Acquired Business or in
which ESI or EHGI has utilized any of the Acquired Assets during the five (5)
years preceding the date of this Agreement.

         (10)     Subsidiaries, Etc. No Subsidiary of ESI or EHGI (other than
EHGI), directly or indirectly, owns any of the Acquired Assets or conducts any
part of the Acquired Business. EHGI is not a partner of or joint venturer with
any other person or Entity in relation to any of the Acquired Assets or any
portion of the Acquired Business.


                                       13
<PAGE>   14

         (11)     Employee Benefit Plans. EHGI does not maintain or contribute
to any Pension Plan or any Welfare Plan, nor is EHGI presently, nor has it been
within the last six years, a participating employer in any Multi-employer Plan
affecting, in any case, employees of EHGI.

         (12)     Facilities. To ESI and EHGI's knowledge (as applied to all of
the following), the Acquired Facilities are (as to physical plant and structure)
structurally sound and none of the Acquired Facilities, nor any of the vehicles
or other equipment used by EHGI in connection with the Acquired Business has any
material defects and all of them are in all material respects in good operating
condition and repair and are adequate for the uses to which they are being
utilized; none of such Acquired Facilities, vehicles or other equipment is in
need of maintenance or repairs except for ordinary, routine maintenance and
repairs (normal wear and tear excepted) which are not material in nature or
cost. EHGI is not in any material breach, violation or default of any lease
affecting the Acquired Business or the Acquired Assets with respect to, or as a
result of which, the other party, whether lessor, lessee, sublessor, or
sublessee thereto, has the right to terminate the same and neither ESI nor EHGI
have received notice of any claim or assertion that it is or may be in any such
breach, violation or default.

         (13)     Accounts Receivable. All accounts receivable of EHGI reflected
in the Acquired Business Balance Sheet represent transactions in the ordinary
course of business, and are collectible, net of any reserves. As of the date
specified therein, the Acquired Business Disclosure Document specifically
identifies (a) the aging of Receivables, (b) each Receivable in excess of $
10,000, (c) each Receivable in an amount in excess of $5,000 that is more than
90 days past due, and (d) each Receivable from a person or Entity from whom the
aggregate of such Receivables exceeds $10,000.

         (14)     Inventories. All Inventories of EHGI reflected in the Acquired
Business Balance Sheet are of quality and quantity usable and salable in the
ordinary course of business except for obsolete items and items of
below-standard quality, all of which, in the aggregate, are immaterial in
amount. Items included in EHGI's Inventories are carried on the books of EHGI,
and are valued on the Acquired Business Balance Sheet consistent with GAAP (as
qualified in Section 1.48 above).

         (15)     Contracts. The Acquired Assets and the Acquired Business are
not affected by any contracts, agreements or understandings, whether express or
implied, written or verbal, provided, however, that the Acquired Assets or the
Acquired Business may be affected by, and the Acquired Business Disclosure
Document need not identify, any such contracts, agreements, or understandings
that fall into one of the following categories: (a) those that are terminable on
notice of less than thirty-two (32) days and do not involve payments or
obligations of more than $10,000 In any period of thirty-one (31) days or less
(on termination or otherwise); or (b) those that involve aggregate payment or
obligation remaining unpaid as of the date of the Agreement of less than
$10,000. All items excluded in (b) above represent, in the aggregate, less than
$100,000. Neither ESI nor EHGI is a party to any executory contract to sell or
transfer any part of any leasehold interest included in the Acquired Assets or
utilized by the Acquired Business. True and accurate copies of all leases of
properties included in the Acquired Assets or utilized by


                                       14
<PAGE>   15

the Acquired Business, including all amendments, supplements, extensions and
modifications thereof, have heretofore been delivered to the Purchaser by EHGI.

         (16)     Accounts Payable. The accounts payable reflected on the
Acquired Business Balance Sheet do, and those reflected in the most recent
balance sheet included in the Unaudited Financial Statements do, and those
reflected on the books of EHGI at the time of the Closing will, reflect all
amounts owed by EHGI in respect of trade accounts due and other Payables of the
Acquired Business or relating to the Acquired Assets, and the actual Liability
of EHGI in respect of such obligations was not, and will not be, on any of such
dates, in excess of the amounts so reflected on the balance sheets or the books
of the Acquired Business, as the case may be.

         (17)     Labor Matters. To the best of the knowledge of ESI and EHGI,
there are no activities or controversies, including without limitation, any
labor organizing activities, election petitions or proceedings, proceedings
preparatory thereto, unfair labor practice complaints, labor strikes, disputes,
slowdowns, or work stoppages, pending or, threatened, affecting the employees of
EHGI.

         (18)     [Omitted]

         (19)     Title to and Utilization of Real Properties and Leasehold
Estates. Except as disclosed in the Acquired Business Disclosure Document, EHGI
owns fee, simple or a valid leasehold interest in, all real property included in
the Acquired Assets and has the unbridled right to use the same (other than
those customarily held by a lessor or licensor in a lease or license of real
property), and is not aware of any claim, notice or threat to the effect that
its right to own and use such property is subject in any way to any challenge,
claim, assertion of rights, proceedings toward condemnation or confiscation, in
whole or in part, or is otherwise subject to challenge. To ESI and EHGI's
knowledge, each parcel of real property the ownership of, or leasehold interest
in, which is included among the Acquired Assets is free of any and all hazardous
wastes, toxic substances, or other types of contamination in quantities or
conditions requiring remediation, and EHGI is not subject to any Liability
resulting from or related to any such wastes, substances or contaminants in
connection with any such property.

         5.7      Full Disclosure. The documents, certificates, and other
writings furnished or to be furnished by or on behalf of ESI and/or EHGI to the
Purchaser pursuant to the provisions of this Agreement, taken together in the
aggregate, do not and will not contain any untrue statements of a material fact,
or omit to state any material fact necessary to make the statements made, in the
light of the circumstances under which they are made, not misleading.

         5.8      Actions Since Balance Sheet Date. Except as set forth on the
Acquired Business Disclosure Document, since the date of the Acquired Business
Balance Sheet, neither ESI nor EHGI has taken any actions that would be
prohibited under the provisions of this Agreement (without the prior consent of
the Purchaser) after the date of this Agreement.

                                   ARTICLE VI
                           COVENANTS OF THE PURCHASER

         6.1      Affirmative Covenants. From the date hereof through the
Closing Date, the Purchaser will use commercially reasonable efforts to satisfy
the conditions to Closing set forth in this Agreement and otherwise to ensure
the prompt and expedient consummation of the Transaction substantially as
contemplated by this Agreement, and will use commercially reasonable efforts to
cause the Transaction to be consummated, provided in all instances that the
representations and warranties of ESI and EHGI in this Agreement are and remain
true and accurate in all material respects and that the covenants and agreements
of ESI and EHGI in this Agreement are honored and that the conditions to the
obligations of the Purchaser set forth in this Agreement are not incapable of
satisfaction.

         6.2      Cooperation. The Purchaser shall reasonably cooperate with ESI
and EHGI and its counsel, accountants and agents in every way in carrying out
the Transactions contemplated herein, and in delivering all documents and
instruments deemed reasonably necessary or useful by EHGI.

         6.3      Expenses. Whether or not the Transaction is consummated, all
costs and expenses incurred by the Purchaser in connection with the preparation
of this Agreement and in preparation for the Transactions contemplated hereby
shall be paid by the Purchaser.

         6.4      Publicity. Prior to the Closing any written news releases by
the Purchaser pertaining to this Agreement or the Transaction shall be submitted
to ESI for review and approval prior to release by the Purchaser, and shall be
released only in a form approved by ESI, provided, however, that (1) such
approval shall not be unreasonably withheld, and (2) such review and approval
shall not be required of releases by the Purchaser if prior review and approval
would prevent the timely and accurate dissemination of such press release as
required to comply, in the judgment of counsel, with any applicable law, rule or
policy.

         6.5      Offers of Employment. Subject to the terms and conditions of
this Agreement, promptly after the Closing, Purchaser shall offer employment to
all employees of EHGI other than those set forth in Schedule 6.5, on terms and
conditions acceptable to Purchaser. Purchaser shall not be liable for any
liabilities associated with any employee terminated by ESI or EHGI.
Notwithstanding the foregoing, the Purchaser shall assume responsibility for
compensation for all employees of EHGI, other than those indicated in Schedule
6.5, accrued after the last payroll period immediately prior to the Closing to
the extent consistent with the historical payroll practices of EHGI and the
Acquired Business. The Purchaser shall not assume responsibility for any
scheduled or unscheduled payroll payments due the employees of the Acquired
Business indicated on Schedule 6.5 for any form of compensation which may be
accrued by such employees. The Purchaser will include in its offers of
employment to all employees, other than those indicated in Schedule 6.5, the
same number of days of vacation accrued by such employees, as employees of EHGI,
as of the Closing Date if, and only if, EHGI is not required by law to pay such
accrued vacation to the employees upon their termination by EHGI (assuming that
Purchaser makes the offers of employment contemplated in this Section 6.5). The
Purchaser


                                       16
<PAGE>   17

will not be liable, in any manner, for any payments or other compensation which
may be required to be paid to such employees upon their termination by EHGI
pursuant to any federal, state or local law or rule.

         6.6      Cooperation. Purchaser acknowledges that post-Closing, ESI
intends to cause EHGI to be dissolved, its assets liquidated and its affairs
wound up. Purchaser will reasonably cooperate with ESI, EHGI and their
respective counsel, accountants, agents and representatives in every way in that
regard and in executing and delivering all documents and instruments deemed
reasonably necessary or useful by ESI or EHGI in that regard. Without limiting
the foregoing, Purchaser shall use its best efforts to cause those employees of
EHGI who currently are officers of EHGI and who become employed by Purchaser to
remain as officers of EHGI, without compensation, and shall use its best efforts
to cause such employees to execute and deliver, on behalf of EHGI, the documents
and instruments contemplated in the immediately preceding sentence and to
otherwise further the dissolution, liquidation and winding up of EHGI, as
directed by ESI; provided, however, that Purchaser shall not be required to take
any action which may expose Purchaser or any of its officers, directors,
employees or agents to any liability in connection with such action. EHGI shall
reimburse Purchaser for any and all reasonable out-of-pocket expenses which it
incurs and pays in connection with it duties and obligations under this Section
6.6, but EHGI shall not be required to reimburse Purchaser for the time spent by
its employees in furtherance of such duties and obligations. Purchaser shall use
its best efforts to retain, and on request, shall provide ESI and EHGI with
access to or copies of, all documents which ESI and/or EHGI may reasonably
request in connection with the dissolution, liquidation and winding up of EHGI
or in preparing and filing any and all tax returns and financial statements for
any periods ending on or prior to December 31, 2000, or in connection with any
audit activities in respect of any periods ending on or prior to December 31,
2000.

                                   ARTICLE VII
                            COVENANTS OF ESI AND EHGI

         7.1      Affirmative Covenants. From the date hereof through the
Closing Date, ESI and EHGI will take every action reasonably required of it to
satisfy the conditions to Closing set forth in this Agreement and otherwise to
ensure the prompt and expedient consummation of the Transaction substantially as
contemplated hereby, and will exert all reasonable efforts to cause the
Transaction to be consummated, provided in all instances that the
representations and warranties of the Purchaser in this Agreement are and remain
true and accurate and that the covenants and agreements of the purchaser in his
Agreement are honored and that the conditions to the obligations of ESI and EHGI
set forth in this Agreement are not incapable of satisfaction.

         7.2      Employment Contracts. Pending the Closing, and effective upon
the consummation of the Transaction, ESI and EHGI will reasonably cooperate with
the Purchaser's efforts to have executed one (1) year employment contracts
between the Purchaser and each of the persons identified on Schedule 7.2, at an
annual salary equal to that set forth for such individual in such schedule; such
contracts shall provide that the Acquired Business may


                                       17
<PAGE>   18

terminate them at any time for cause, or without cause may terminate them upon
sixty (60) days prior written notice.

         7.3      Covenant Not to Compete. ESI and EHGI will execute a five (5)
year noncompetition agreement with the Purchaser to preclude ESI and EHGI from
engaging in any business competitive with that of the Acquired Business,
directly or indirectly, alone or in collaboration with others, except with the
written consent of the Purchaser or as a shareholder of less than one percent
(1%) of the common stock of a publicly held company engaged in one or more of
such businesses and with such other terms as are mutually acceptable to ESI,
EHGI and Purchaser.

         7.4      Access and Information. Subject to the terms and conditions of
the existing confidentiality agreement between ESI and the Purchaser (the terms
and conditions of which are incorporated herein by reference), between the date
of this Agreement and the Closing Date ESI and EHGI shall afford to the
Purchaser and to the Purchaser's accountants, counsel, and other representatives
reasonable access during normal business hours throughout the period prior to
the Closing to all of its and its Subsidiaries properties, books, contracts,
commitments, records (including, but not limited to, tax returns), and personnel
relating to the Acquired Assets or the Acquired Business and, during such
period, shall furnish promptly to the Purchaser (1) all written communications
to its directors or to its shareholders generally relating to the Acquired
Assets or the Acquired Business, (2) internal monthly financial statements of
the Acquired Business when and as available, and (3) all other information
relating to the Acquired Assets or the Acquired Business as the Purchaser may
reasonably request, but no investigation pursuant to this Section 7.4 shall
affect any representations or warranties of ESI or EHGI , or the conditions to
the obligations of the Purchaser to consummate the Transaction contained in this
Agreement. Purchaser and its representatives shall use their best efforts to
assert their rights hereunder in such a manner as to minimize interference with
the business of ESI and EHGI.

         7.5      No Solicitation. Until the Closing Date or the termination of
this Agreement in accordance with its terms, ESI and EHGI, and those acting on
behalf of any of them will not, and ESI and EHGI will use its best efforts to
cause its officers, employees, agents, and representatives (including any
investment banker) to not, directly or indirectly, solicit, encourage, or
initiate any discussions with, or negotiate or otherwise deal with, or provide
any information to, any person or Entity other than the Purchaser and its
officers, employees, and agents, in relation to the Acquired Assets or the
Acquired Business. ESI or EHGI will notify the Purchaser immediately upon
receipt of an inquiry, offer or proposal relating to any of the foregoing. None
of the foregoing shall prohibit providing information to others in a manner in
keeping with the ordinary conduct of the ESI or EHGI's business, or providing

                           Attendant Documents,

                  (2)      any breach or failure of the Purchaser to perform any
                           covenant or agreement required to be performed by the
                           Purchaser pursuant to this Agreement or any of the
                           Attendant Documents including, without limitation,
                           Purchaser's obligations to pay the Assumed
                           Liabilities under Section 2.1 above;

                  (3)      any and all Related Expenses incident to any of the
                           foregoing.

         10.3     Remedies Not Exclusive. The Purchaser Parties and the Seller
Parties shall be entitled to exercise and resort to all rights and remedies for
misrepresentation or breach as are afforded at law or in equity, including,
without limitation, rescission, specific performance or such other non-monetary
remedies and relief as may be afforded under this Agreement or by a court of
competent jurisdiction. Neither the existence or exercise of any specific
remedies is intended to be exclusive or impair or otherwise adversely affect in
any manner whatsoever any rights, remedies or relief otherwise available, and
each and every right and remedy will be cumulative and in addition to every
other right and remedy provided in this Agreement or by law. Notwithstanding the
foregoing, other than actions for fraud or other intentional torts, the


                                       25
<PAGE>   26

remedies set forth in this Article 10 shall be the Purchaser Parties' and the
Seller Parties' sole and exclusive remedies relative to the recovery of economic
or monetary damages.

         10.4     Procedures. If any proceedings are instituted or any claim or
demand is asserted by any person not a party to this Agreement in respect of
which any of the Purchaser Parties or the Seller Parties may seek
indemnification pursuant to this Section 10, the indemnified party shall
promptly cause written notice (the "Notice") of the assertion of any such claim
or demand to be made to the indemnifying party; provided, however, that the
failure of the indemnified party to give prompt Notice shall not relieve the
indemnifying party of its obligations hereunder unless, and only to the extent
that, such failure caused the damages for which the indemnifying party is
obligated to be greater than they would have been had the indemnified party
given the indemnifying party prompt Notice hereunder. Except as otherwise
provided herein, the indemnifying party shall have the right, at its option and
expense, to defend against, negotiate, or settle any such claim or demand, and
if the indemnifying party exercises that option, the indemnifying party shall
not be liable for the fees and expenses incurred after the date the indemnifying
party notifies the indemnified party of such exercise by a counsel employed by
the indemnified party. An indemnifying party may not settle any such claim or
demand without the written consent (which consent shall not be unreasonably
withheld, conditioned or delayed) of the indemnified party unless such
settlement requires no more than a monetary payment for which the indemnified
party is fully indemnified or involves other matters not binding upon the
indemnified party. An indemnifying party shall not be liable for any settlement
of any such claim or demand effected without its prior written consent (which
consent shall not be unreasonably withheld, conditioned or delayed). In the
event that the indemnifying party shall fail to respond within ten (10) days
after the giving of the Notice, then the indemnified party may retain counsel
and conduct the defense thereof as it may, in its sole discretion, deem proper,
at the sole cost and expense of the indemnifying party. The parties agree to
cooperate fully with each other in connection with the defense, negotiation or
settlement of any such legal proceeding, claim or demand.

         10.5     Cooperation. The Purchaser shall, and shall cause its
accountants, counsel, employees and other representatives to, reasonably
cooperate with ESI and EHGI in connection with any and all disputes which may
arise in connection with any and all Liabilities other than the Assumed
Liabilities (the "Excluded Liabilities"). ESI and EHGI shall, and shall cause
its accountants, counsel, employees and other representatives to, reasonably
cooperate with the Purchaser in connection with any and all disputes which may
arise in connection with any and all of the Assumed Liabilities. Without
limiting the generality of the foregoing, the Purchaser shall cause its
accountants, counsel, employees and other representatives, to make available to
ESI or EHGI, their employees, work papers, documents and other information and
materials reasonably requested by ESI or EHGI in connection with the Excluded
Liabilities and ESI and EHGI shall cause its respective accountants, counsel,
employees and other representatives, to make available to the Purchaser, its
employees, work papers, documents and other information and materials reasonably
requested by the Purchaser in connection with the Assumed Liabilities. The party
requesting cooperation (ESI and EHGI in connection with the Excluded Liabilities
or the Purchaser in connection with the Assumed Liabilities) shall pay all
out-of-pocket expenses reasonably incurred and paid by the cooperating party to
third parties in connection with such


                                       26
<PAGE>   27

cooperative efforts; provided, however, that the party requesting cooperation
shall not be obligated to reimburse the cooperating party for the time spent by
any of their or their Affiliates' employees' time spent in connection with such
cooperative efforts.

         10.6     Initial Limitation. Other than the rights to defend and hold
harmless with respect to third party claims, neither Party (defined below) shall
have any liability for indemnification pursuant to Section 10.1 and Section
10.2, above, until the aggregate amount of all losses suffered by the Party
seeking indemnification with respect to such matters exceeds the sum of
$100,000; provided, however, that this limitation shall not apply to breaches by
EHGI of its obligations under Section 7.11 above or Purchaser of its obligations
to pay the Assumed Liabilities. For purposes of this Section 10.6 and Section
10.7 below, Purchaser, on the one hand, and ESI and EHGI, collectively, on the
other hand, shall each constitute a "Party."

         10.7     Aggregate Limitation. The aggregate liability, for either
Party, for indemnification pursuant to Section 10.1 or Section 10.2, above,
shall not exceed the sum of $10,000,000; provided, however, that this limitation
shall not apply to breaches by EHGI of its obligations under Section 7.11 above
or Purchaser of its obligations to pay the Assumed Liabilities.

         10.8     Available Insurance Limitation. The amount of any recovery for
indemnification pursuant to Section 10.1 or Section 10.2, above, shall be
determined after taking into account all amounts to which the indemnified party
is entitled and actually receives under the provisions of all insurance policies
with third parties (i.e. actual insurance policies and not self-insurance or
retention programs) subject to offset for any increase in premiums attributable
to such losses or payments made in respect of such losses. The parties agree to
use reasonable efforts to collect amounts available under any such insurance
policies.

         10.9     Balance Sheet Adjustment Limitation. With respect to any claim
of indemnification related to any breach of Sections 5.5, 5.6(l), 5.6(13),
and/or 5.6(14) or any other representation or warranty concerning the Unaudited
Financial Statements, the amount of any recovery by the Purchaser Parties for
indemnification pursuant to Section 10.1, above, as a result of any breach of
Sections 5.5, 5.6(l), 5.6(13), and/or 5.6(14) or any other representation or
warranty concerning the Unaudited Financial Statements, shall be reduced by any
Balance Sheet Gains (defined below). Upon any such claim for recovery, or upon
the reasonable request of ESI or EHGI after a claim has been made by Purchaser
hereunder, Purchaser shall deliver to ESI or EHGI a report identifying Balance
Sheet Gains or will represent in writing that there are no Balance Sheet Gains.
For purposes of this Agreement, the term "Balance Sheet Gains" means any
realization with respect to any current asset in excess of its value as
reflected on the Acquired Business Balance Sheet (as adjusted to account for any
ordinary course changes thereto through the Closing Date), or any positive
realization with respect to any Liability reflected on the Acquired Business
Balance Sheet (as adjusted to account for any ordinary course changes thereto
through the Closing Date) (in that the Purchaser is actually responsible for any
amount less than that reflected thereon).

         10.10    Application of Indemnification Provisions. The parties agree
that the limitations of the indemnification provisions contained in Sections
10.6, 10.7, 10.8 and 10.9 above do not apply to the parties' rights and
obligations to defend and hold harmless with regard to third party


                                       27
<PAGE>   28

claims, pursuant to Sections 10.1 and 10.2 above, and shall apply on a
collective basis to all agreements for indemnification including those to be
entered into in respect of each of the Related Transactions, pursuant to Section
3.1 above. For example, a claim for indemnification as a result of a balance
sheet adjustment, pursuant to Section 10.9 above, shall be determined after
taking into account any positive adjustments to the Acquired Business Balance
Sheet or to the balance sheets of any foreign jurisdiction entities (as set
forth in Section 3.1 above) and shall similarly be accompanied by the report or
representation contemplated in Section 10.9 above. The parties further agree
that the Purchaser's right to put any Receivables back to ESI or EHGI, as and to
the extent provided in Section 11.1 below, shall be determined on a collective
basis, taking into consideration all receivables of EHGI and all of the foreign
entities identified in Section 3.1 above, the Purchaser's or its Affiliates'
collection efforts, and the aggregate reserves of EHGI and all of the foreign
entities identified in Section 3.1 above.

                                   ARTICLE XI
                               GENERAL PROVISIONS

         11.1     Collection of Accounts Receivable. Upon and after the Closing,
the Purchaser shall have the right and authority to collect all Receivables
transferred to Purchaser pursuant to this Agreement and to endorse the name of
EHGI on any checks received on account of any such Receivables. ESI and EHGI
shall promptly transfer and deliver to Purchaser any cash, checks or other
property which ESI and EHGI may receive in respect of such accounts after the
Closing Date. ESI and EHGI will cooperate with Purchaser, at its reasonable
request, on and after the Closing Date in endeavoring to collect all Receivables
transferred to Purchaser by furnishing, at Purchaser's cost and expense, such
information, testimony and other assistance as Purchaser may reasonably require
in connection with collection of such accounts. Payments received from customers
in respect of any Receivables shall be applied to the oldest outstanding
Receivable from such customer, unless such customer, acting on its own volition,
specifically identifies such payment to a particular Receivable, in which case
such payment shall be applied to the specified Receivable. Purchaser hereby
agrees not to coerce or suggest, directly or indirectly, in any way, to any
customer that they identify any payment to a particular Receivable, and in the
event of any such coercion or suggestion Purchaser agrees to make a credit to
ESI or EHGI, for any Receivables put to ESI or EHGI as provided below, in an
amount equal to five times the amount of that Receivable. Purchaser shall use
commercially reasonable efforts to collect the Receivables (but shall not be
obligated hereunder to bring any action to collect any Receivables) but if it
shall fall to collect the full amount of any such Receivable within 180 days
after the Closing Date, Purchaser shall have the right to put such Receivable to
EHGI (or ESI, if EHGI is no longer in existence), whereupon ESI or EHGI (as
applicable) shall repurchase such Receivable from Purchaser at the face amount
thereof; provided, however, that ESI or EHGI (as applicable) shall not have any
obligation to repurchase any Receivables until the aggregate amount of
Receivables which Purchaser has a right to, and has elected to, put to ESI or
EHGI (as applicable) exceeds the amount of any reserve for such Receivables as
of the Closing Date and then only to the extent of such excess. Any such put
right must be exercised on or before 360 days after the Closing Date unless
extended in writing by ESI. Notwithstanding the foregoing, Purchaser shall not
have the


                                       28
<PAGE>   29

right to put to ESI or EHGI (as applicable) any Receivable which Purchaser has
compromised or settled or agreed to accept payment at less than the face amount
thereof in full satisfaction thereof or otherwise given a credit in respect
thereof. Upon a put of a receivable to ESI or EHGI, Purchaser will cooperate
with ESI or EHGI, at its reasonable request, in endeavoring to collect all
Receivables put to ESI or EHGI by furnishing, at ESI or EHGI's cost and expense,
such information, testimony and other assistance as ESI or EHGI may reasonably
require in connection with collection of such accounts.

         11.2     Maintenance and Support of Performer. After the Closing, upon
a sale by Purchaser of the Software Product commonly referred to as "Performer"
and the entering into of an agreement for its maintenance and support, Purchaser
and ESI agree that Purchaser shall subcontract with ESI, or any Subsidiary of
ESI as designated by ESI, for purposes of providing such maintenance and
support. The terms and conditions shall be substantially similar to those
currently utilized by EHGI for the maintenance and support of Performer;
provided, however, that ESI shall be responsible for invoicing and collecting
all maintenance and support fees generated thereunder. Notwithstanding the
foregoing, Purchaser shall be responsible for the management of the Performer
customer accounts. On or before the 15th day of each month, ESI shall deliver to
Purchaser an amount equal to 15% of all such fees which ESI collected during the
previous month. Upon 90 days written notice, either ESI or Purchaser shall have
the right to terminate their obligations hereunder. Upon a termination,
Purchaser and ESI shall use commercially reasonable efforts to complete the
invoicing, collection and division of all previously accrued maintenance and
support fees generated from the subcontracting of such services by Purchaser to
ESI.

         11.3     Asset Acquisition Statement. Prior to the Closing, the parties
agree to jointly prepare and file the Asset Acquisition Statement on Form 8594,
as required by the Internal Revenue Service, and to use commercially reasonable
methods to determine the allocation of the Consideration to be disclosed
therein.

         11.4     Arbitration. In the event that there shall be a dispute
arising out of or relating to this Agreement, the Transaction, any document
referred to herein or centrally related to the subject matter hereof, or the
subject matter of any of the same, the parties agree that such dispute shall be
submitted to binding arbitration in Los Angeles County, California, under the
auspices of, and pursuant to the rules of, the American Arbitration Association
as then in effect, or such other procedures as the parties may agree to at the
time, before an arbitrator selected pursuant to the rules of the American
Arbitration Association. Any award issued as a result of such arbitration shall
be final and binding between the parties, and shall be enforceable by an court
having jurisdiction over the party against whom enforcement is sought.

         11.5     Notices. All notices and other communications required or
permitted hereunder shall be in writing and shall be deemed given if and when
delivered personally or three (3) business days following mailing by registered
or certified mail (return receipt requested) to the parties at the following
addresses or at such other address for a party as shall be specified by like
notice given.

                 If to the Purchaser:

         11.6     Interpretation. The headings contained in this Agreement are
for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

         11.7     Survival of Representations, Warranties, Etc. The
representations, warranties, covenants, and agreements of the parties contained
herein shall survive the Closing and any investigation of the other party made
prior thereto. Representations and warranties shall so survive for a period of
three (3) years from the Closing, except for those contained in Sections 4.1,
4.2, 4.3, 5.1, 5.2 and 5.3 which shall survive indefinitely, and for those
contained in Section 5.5 which shall survive until March 31, 2001.

         11.8     Miscellaneous. This Agreement and the existing confidentiality
agreement referenced in Section 7.4 constitute the entire agreement and
supersedes all of the prior agreements and understandings, both written and
oral, between the parties, with respect to the subject matter hereof, except as
specifically provided otherwise or referred to herein, so that no such external
or separate agreements relating to the subject matter of this Agreement (1)
shall have any effect or be binding, unless the same is referred to specifically
in this Agreement or is executed by the parties after the date hereof, (2) is
not intended to confer upon any other person any rights or remedies hereunder;
(3) shall not be assigned by operation of law or otherwise


                                       30
<PAGE>   31

except for assignments of all or any part of the rights of the Purchaser
hereunder, which may be freely assigned by the Purchaser so long as the
obligations of the Purchaser under this Agreement remain obligations of, or
their performance is unconditionally guaranteed (which must be a guaranty of
performance, and not just collection, with no duty on the part of ESI or EHGI to
pursue the assignee first, and which guarantee must be approved by ESI in
advance, which approval will not be unreasonably withheld) by, the Purchaser;
and (4) shall be governed in all respects, including validity, interpretation
and effect, by the internal laws of the State of California, without regard to
the principles of conflict of laws thereof. It is acknowledged and understood by
ESI and EHGI that Purchaser may assign it rights, but not its obligations,
hereunder, after execution and prior to the Closing, to one or more wholly-owned
(direct or indirect) Subsidiaries of Purchaser. This Agreement may be executed
in two or more counterparts which together shall constitute a single agreement
and facsimile signatures shall have equal dignity with original signatures for
all purposes.

         11.9     Certain Exhibits. The parties acknowledge that they have not
yet finalized the documents to be attached to this Agreement as Exhibits 8.1(7),
8.1(12), 8.1(13), 8.2(6) and 8.2(9) but they agree that they shall endeavor in
good faith to do so by the close of business on October 5, 2000. Each party's
approval of those documents prior to the Closing shall be an additional
condition precedent to its obligations to consummate the Transaction.

                           [INTENTIONALLY LEFT BLANK.]
