the other stockholders of I-NET, Inc. signatories thereto (the "Other

subordinated promissory notes, in the principal aggregate face amount of

Government as required by law or pursuant to Contracts with the United States

restrictively marked technical data or computer software as unlimited rights
data or software. For purposes of this Section 3.20(f), the terms first used in

            Section 4.1  ORGANIZATION AND QUALIFICATION. Wang is a corporation
duly organized, validly existing and in good standing under the laws of the

carry on its businesses as they are now being conducted. Wang is duly qualified

subscription, option, warrant, call, right, agreement, commitment, understanding
or arrangement relating to the issuance, sale, delivery, transfer or redemption
of any capital stock of Wang (including, except as set forth on Schedule 4.3(a),
any right of conversion or exchange under any outstanding security or other
instrument) other than, in the case of Wang Common Stock, in each case as of

qualifying shares or as set forth in Schedule 4.3(b)).

                  (c) If Wang issues any shares of Wang Common Stock in partial
payment of the Notes, such shares when so issued will be duly authorized,
validly issued, fully paid, nonassessable and free of preemptive rights.

            Section 4.4  CONFLICTING AGREEMENTS AND CHARTER PROVISIONS. Except
as set forth in Schedule 4.4, none of (a) the execution and delivery of this
Agreement by Wang, (b) the fulfillment of or compliance with the terms and
provisions hereof by Wang or (c) the consummation of any of the transactions
contemplated hereby by Wang will conflict with or result in a breach of the
terms, conditions or provisions of, or give rise to a right of termination
under, or constitute a default under, or result in the loss of any right or
benefit under or result in any violation of (in each case with or without the
giving of notice or the passage of time or both), the certificate of
incorporation or bylaws of Wang or any mortgage, Contract, License, order,
arbitration award, judgment, decree, statute, law, rule or regulation to which
Wang is a party or it or any of its property is subject, except for such
conflicts, breaches, rights of termination, defaults, losses or rights or
benefits, or violations which, individually or in the aggregate, could not
reasonably be expected to have a Wang Material Adverse Effect.

            Section 4.5  DEFAULT. No default exists and no event has occurred
which with notice, lapse of time, or both, would constitute a default, in the
due performance and observance of any term, covenant or condition of any
indenture or other agreement or instrument to which Wang or any of its
subsidiaries is a party or by which it or any of them is bound, except such
defaults which would not have a Wang Material Adverse Effect.

            Section 4.6  REPORTS; FINANCIAL STATEMENTS. (a) Since January 1,
1994, Wang has filed all forms, reports and documents with the Commission
required to be filed by it pursuant to the Securities Act or the Exchange Act

                                       49


<PAGE>   54


Securities Act or the Exchange Act. None of such forms, reports or documents,
including, without limitation, any financial statements or schedules included
therein, at the time filed, contained any untrue statement of a material fact or
omitted to state a 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.

                  (b) The consolidated financial statements included in the
forms, reports and documents referred to in Section 4.6(a) present fairly the
financial position, results of operations, stockholders' equity and cash flows
of Wang as of their respective dates or for the periods then ended, as
applicable, except that the unaudited interim financial statements were or are
subject to normal and recurring year-end adjustments which were not and are not
expected to be material in amount, and have been prepared in conformity with
GAAP.

            Section 4.7  CHANGES SINCE THE MOST RECENT AUDITED FINANCIAL
STATEMENTS. Except as set forth on Schedule 4.7, since the date of the most
recent audited financial statements of Wang and through and as of the date of
this Agreement, there has not been any change, event or occurrence (or, to the
knowledge of Wang, any threat thereof) which individually or in the aggregate,
has resulted in, or could reasonably be expected to result in, a Wang Material
Adverse Effect.

            Section 4.8  LITIGATION; ORDERS. Except as set forth in Schedule 4.8
or the Wang Reports, there are no lawsuits, actions, administrative or
arbitration or other proceedings or governmental investigations pending or, to
the knowledge of Wang, threatened against Wang or otherwise involving Wang which
(a) could reasonably be expected to result in the issuance of an order,
judgment, injunction or decree restraining, enjoining or otherwise prohibiting
or making illegal the consummation of any of the transactions contemplated by
this Agreement or (b) if adversely determined, could have a Wang Material
Adverse Effect. Except as set forth in the Wang Reports, there are no judgments
or outstanding orders, injunctions, decrees, stipulations or awards (whether
rendered by a court or administrative agency, or by arbitration) against Wang or
against or affecting any of Wang's properties or businesses which has had or
could



                                       50


<PAGE>   55


reasonably be expected to have a Wang Material Adverse Effect.

            Section 4.9  LICENSES; CONSENTS; COMPLIANCE WITH LAWS. (a) Schedule
4.9(a) contains a list of all Consents required to be made or given to, or
obtained from, any Person by Wang under the certificate of incorporation or
bylaws of Wang, or any mortgage, Contract, License, order, arbitration award,
judgment, decree, statute, law, rule, regulation or other restriction of any
kind or character to which Wang is a party or any of its property is subject to
or otherwise in connection with the execution and delivery of this Agreement by
Wang, the fulfillment of or compliance with the terms and provisions of this
Agreement by Wang, or the consummation of the transactions contemplated by this
Agreement by Wang.

                  (b) The businesses of Wang are being and have been conducted
in compliance in all material respects with the certificate of incorporation and
bylaws of Wang, and with all applicable laws, statutes, ordinances, rules and
regulations of any governmental department, commission, board, bureau, agency or
instrumentality of the United States, any state or political subdivision
thereof, or any foreign jurisdiction, and all applicable court decrees, awards,
orders, writs, injunctions permits and judgments (except for violations, which
could not, individually or in the aggregate, reasonably be expected to have a
Wang Material Adverse Effect or which have been cured).

                  (c) Wang and each of its subsidiaries have received and are
operating in compliance with all Consents, licenses, authorizations, approvals,
orders, certificates and permits of and from, and have made or will have made,
as the case may be, all declarations and filings with, all federal, state, local
and other governmental authorities, all self regulatory organizations and all
courts and other tribunals, as are required to own, lease, license and use their
respective properties and assets and to conduct their respective businesses, in
the manner and to the extent described in Wang Reports, except to the extent
that the failure to obtain or file would not have a Wang Material Adverse
Effect.

                  (b) Each of the Sellers shall reimburse the Company, in cash
(or provide Wang with written notice of its election to exercise the right of
set-off pursuant to the last sentence of this Section 5.10(b)), for its share of
the amount due under the Lamb Settlement Agreement, such share to be determined
by multiplying (i) the aggregate market value of the shares of Company Common
Stock issued pursuant to the Lamb Settlement Agreement or (ii) if the Company
repurchases the shares of Company Common Stock issued pursuant to the Lamb

C hereto, not later than five business days after the date on which the Company
notifies such Seller of such Seller's share. Any Seller obligated to reimburse
Wang for any amounts paid by Wang pursuant to this Section 5.10(b) may elect, by

termination of the employment of any of the executives party to a Severance
Protection Agreement by any such executive (i) during the 90 day period after
the date of the occurrence of any event or condition constituting Good Reason
pursuant to Section 2.15(a)(1) of such Severance Protection Agreement or (ii)
during the 90 day period commencing six months after the occurrence of the
Change in Control (as defined in such Severance Protection Agreements) resulting

right of set-off pursuant to Section 5.11(c)), for its share of any amounts paid
in cash by Wang or the Company, as the case may be, to any executive party to
any of the Severance Protection Agreements, attributable to such executive's
relinquishment of his or her rights under his or her Severance Protection
Agreement in connection with any such executive entering into a new employment

to be determined by multiplying (x) the lesser of (A) the cash amount so paid by
Wang or the Company, as the case may be, to such executive to relinquish such
rights or (B) the maximum amount payable under such executive's Severance
Protection Agreement upon termination of the employment of such executive under
circumstances described in Section 5.11(a) by (y) the percentage set forth under

Closing shall automatically become an option to purchase shares of Wang Common
Stock (a "New KESOP Option"), such that the New KESOP Option (i) shall be
exercisable for that number of shares of Wang Common Stock equal to the number
of shares of Company Class E Stock covered by the Old KESOP Option immediately

5.12(d)) (rounded to the nearest whole share), (ii) shall have an exercise price
per share equal to exercise price per share of the Old KESOP Option immediately
prior to Closing divided by the Exchange Ratio (rounded to the nearest whole
cent), (iii) shall be exercisable to the extent vested, (iv) shall terminate on

Plan) shall adopt such resolutions or take such other actions as are necessary
to amend, subject, if necessary, to obtaining con-



                                       61

sents of the holders thereof, the terms of all outstanding options to purchase
shares of Company Class E Stock theretofore granted under the Stock Incentive
Plan (the "Old Incentive Options") to provide for the amendment of the Old
Incentive Options as set forth in Section 5.12(b). Except to the extent that the
holder of an Old Incentive Option elects to receive cash as provided in Section
5.12(e), each Old Incentive Option outstanding immediately prior to the Closing
shall automatically become an option to purchase shares of Wang Common Stock (a
"New Incentive Option"), such that the New Incentive Option (i) shall be
exercisable for that number of shares of Wang Common Stock equal to the number
of shares of Company Class E Stock covered by the Old Incentive Option
immediately prior to Closing multiplied by the Exchange Ratio (rounded to the
nearest whole share), (ii) shall have an exercise price per share equal to
exercise price per share of the Old Incentive Option immediately prior to the
Closing divided by the Exchange Ratio (rounded to the nearest whole cent), (iii)
shall vest one-third, one-third and one-third on the first, second and third
anniversaries of the Closing Date, (iv) shall be exercisable to the extent
vested, (v) shall terminate on the 30th day following the termination of
employment of the holder, (vi) shall have such other customary terms and

consents of the holders of Old KESOP Options or Old Incentive Options necessary
to effect the amendment and modification of the Old KESOP Options and the Old
Incentive Options contemplated by Sections 5.12(a) or (b), respectively, prior
to the Closing. The Sellers shall cause the Company's General Counsel to report
not less than weekly to Wang's General Counsel (or his designee) as to the
consents obtained as of the date of the report, the consents remaining to be
obtained as of the date of the report and the steps being taken to obtain the

                  (e) Immediately prior and subject to the Closing, the Company
shall pay to each holder of an Old KESOP Option or Old Incentive Option who (i)
has consented to the amendment of such options contemplated by Section 5.12(a)
or (b), in a manner satisfactory to Wang, and (ii) so elects, an amount in cash
equal to (x) the number of vested shares covered by such option (whether or not
currently exercisable) multiplied by (y) the excess of $24.87 over the per share
exercise price of such option. Any holder of an Old KESOP Option or Old
Incentive Option who elects to receive cash in lieu of such holder's vested Old
KESOP Options or Old Incentive Options shall be deemed to have exercised such
option to that extent immediately prior to the Closing. Wang shall (i) reserve
for issuance the number of shares of Wang Common Stock that will become issuable
upon the exercise of the New KESOP Options or the New Incentive Options pursuant
to this Section 5.12(a) or (b), (ii) as soon as practicable after the Closing,
execute and deliver option agreements evidencing the New KESOP Options and the
New Incentive Options to the holders thereof and (iii) as soon as practicable
after the Closing, Wang shall file a registration statement on Form S-8 (or any
successor form), or another appropriate form with respect to the shares of Wang
Common Stock subject to the New KESOP Options and the New Incentive Options to
the holders thereof.

                  (f) It is intended that the actions contemplated by Sections
5.12(a) or (b) shall be undertaken in a manner that will not constitute a
"modification" as defined in Section 424 of the Code, as to any Old KESOP Option
or Old Incentive Option which is an incentive stock option.

                  (g) For a period of not less than two years following the
Closing Date, subject to applicable law, Wang will cause the Company to provide
benefits to the Company's employees which will, in the aggregate, be no less
favorable than (i) those provided by the Company



                                       63


<PAGE>   68


and the Company Subsidiaries to their employees immediately prior to the Closing
Date or (ii) those provided by Wang to its similarly situated employees from
time to time. If any salaried employee of the Company becomes a participant in
any employee benefit plan, practice or policy of Wang or any Wang Subsidiary,
such employee shall, to the extent permitted by applicable law, be given credit
under such plan for all service prior to the Closing Date with the Company (to
the extent such credit was given by the Company) and prior to the time such
employee becomes such a participant, for purposes of eligibility and vesting but
not for purposes of any other benefit accrual.

                  (h) Wang hereby agrees that consummation of the transactions
contemplated by this Agreement constitutes a "Change in Control" for purposes of
the Severance Protection Agreements set forth on Schedule 5.12(h).

three years from and after the Closing Date, Wang agrees to indemnify and hold
harmless all past and present officers and directors of the Company or the
Company Subsidiaries to the same extent such persons are indemnified as of the
date of this Agreement by the Company pursuant to the Charter and the Bylaws for
acts or omissions occurring at or prior to the Closing Date. Wang shall provide,
or shall cause the Company to provide, for an aggregate period of not less than
two years from and after the Closing Date, the Company's current directors and
officers with directors' and officers' liability insurance coverage for events
occurring prior to the Closing Date that is no less favorable than the Company's
existing directors' and officers' liability insurance policy in terms of
coverage and amounts; PROVIDED, HOWEVER, that if Wang elects to provide such
coverage under Wang's directors' and officers' liability insurance policy, the
Company's current directors and officers shall provide Wang with such
representations as Wang's directors' and officers' liability insurance carrier
may request; and PROVIDED FURTHER, HOWEVER, that the annual cost to Wang, or the
Company, of such coverage shall not exceed 200 percent of the Company's fiscal
1995 annual premium for its directors' and officers' liability insurance policy

through the Closing Date in accordance with GAAP, shall be for the account of
the Sellers, and Wang or the Company shall pay over to the Sellers in
immediately available funds such refund within fifteen (15) days after receipt

under Sections 6.1(a)(ii), 6.1(a)(iii), 6.1(a)(iv) and 6.1(c) shall be several

the Sellers having such obligations as set forth on Exhibit A hereto (provided,
however, that any obligation under Section 6.1(a) with respect to the
investigation of the General Accounting Office during 1995 referred to in

(i) no Seller shall have any obligation to indemnify any Wang Indemnified
Persons for Losses pursuant to Section 6.1(a)(i) unless and until the aggregate

Losses exceed $500,000; (ii) the aggregate liability of the Sellers pursuant to

(to the extent such Loss does not result from an administrative, civil or
criminal penalty or fine, a criminal conviction or a suspension, debarment or
termination (other than any termination for convenience or termination of a
Contract of the type referred to in Section 3.14(a)(xi) as a result of the
transactions contemplated hereby)), 3.24 (the second sentence), 3.25 or 3.26
shall be limited to $8,333,150 (provided, however, that, notwithstanding the
foregoing $8,333,150 limit, the Sellers, on the one hand, and the Wang
Indemnified Parties, on the other hand, shall share dollar for dollar the first
$8,333,150 of Losses exceeding the foregoing limit involving any Loss arising
out of or relating to, directly or indirectly, any breach of any representation
or warranty in Section 3.20, including, without limitation, any Loss which may,
in accordance with the terms of a Contract, result in a direct or indirect
reduction in Contract price, including interest thereon, to be repaid by the
Company or any Contract modification resulting in an ongoing reduction in
Contract price); (iii) the aggregate liability of the Sellers pursuant to
Section 6.1(a)(i) for Losses incurred by the Wang Indemnified Persons with
respect to breaches of representations and warranties in Section 3.20 to the
extent such Loss results from an administrative, civil or criminal penalty or
fine, a criminal conviction or a suspension, debarment or termination (other
than any termination for convenience or termination of a Contract of the type
referred to in Section 3.14(a)(xi) as a result of the transactions contemplated

warranties in Article III is limited to $166,630,000; and (v) the aggregate
liability of the Sellers pursuant to Section 6.1(c) is limited to $166,630,000.

                  (c) In accordance with this Article VI and in addition to the
indemnification provided for in Section 6.1(a), the Sellers will indemnify and
hold the Wang Indemnified Persons harmless from and against (i)



                                       67


<PAGE>   72


all unpaid liability for Taxes of the Company for all taxable periods ending on
or prior to the Closing Date and the portion for the period which is treated
pursuant to Section 6.2(1) as ending on the Closing Date (the "Pre-Closing Date
Period"), (ii) any liability for Taxes imposed pursuant to Treasury Regulations
[Section] 1.1502-6 (or a comparable provision under state or local Tax law) for
any Pre-Closing Date Period and (iii) liabilities, costs, expenses (including,
without limitation, reasonable expenses of investigation and reasonable
attorney's fees and expenses) arising out of or incident to the imposition,
assertion or assessment of any Tax (including those incurred in the contest in
good faith in appropriate proceedings relating to the imposition, assertion or
assessment of any Tax for any Pre-Closing Date Period (the sum of (i) through   
(iii) being referred to as a "Tax Loss"); PROVIDED, HOWEVER, that the amount of
any Tax Loss shall be reduced to the extent such Tax Loss was specifically
identified and reserved against (as to amount, type of Tax and Tax year) on the
Company Balance Sheet as adjusted for the passage of time through the Closing
Date in accordance with GAAP. The parties agree that, except to the extent
otherwise required by law, the Company shall be entitled to claim any
deductions attributable to cash payments made under Section 5.12(e) in the
final consolidated federal income Tax Return on which the Company is the common
parent. In the case of a Straddle Period, the Company shall also be entitled to
claim in the Pre-Closing Date Period any deductions for such payments for
state, local and foreign purposes.

                  (d) In the case of any taxable period that includes (but does
not end on) the Closing Date (a "Straddle Period"), the Taxes of the Company
attributable to the Pre-Closing Date Period shall be:

                        (i) in the case of Taxes that are either (x) based upon
            or related to income or receipts, or (y) except for Taxes imposed as
            a result of the transactions contemplated hereby, imposed in
            connection with any sale or other transfer or assignment of property
            (real or personal), tangible or intangible, deemed to be equal to
            the amount which would be payable if the taxable year ended with and
            included the Closing Date; and




                                       68


<PAGE>   73


                        (ii) in the case of Taxes not described in subparagraph
            (i) that are imposed on a periodic basis and measured by the level
            of any item, the amount of such Taxes for the entire period (or, in
            the case of such Taxes determined on an arrears basis, the amount of
            such Taxes for the immediately preceding period) multiplied by a
            fraction, the numerator of which is the number of calendar days in
            the period ending on the Closing Date and the denominator of which
            is the number of calendar days in the entire period; PROVIDED,
            HOWEVER, that the Sellers shall have no indemnification obligation
            with respect to any Taxes incurred in a Straddle Period attributable
            to assets contributed to the Company by Wang after the Closing Date.

                  (e) To the extent that the Sellers indemnify the Wang
Indemnified Persons for a Tax Item that produces a Tax benefit in any period
after the Closing Date, the Sellers' indemnification obligation under Section
6.1(c) shall be decreased. To the extent that the Sellers' indemnification
obligation is reduced by a Tax Item that produces a Tax detriment to Wang or the
Company in any period after the Closing Date, the Sellers' indemnification
obligation under Section 6.1(c) shall be increased. The amount of such Tax
benefit or Tax detriment shall be calculated on a "with-or-without" basis when
actually realized.

                  (f) Notwithstanding anything to the contrary in Section
6.1(c), the Sellers shall not indemnify the Wang Indemnified Persons for any
Taxes which arise from Wang making an election under Section 338 of the Code in
connection with this transaction.

            Section 6.2  WANG INDEMNIFICATION. (a) In accordance with this
Article VI, Wang will indemnify and hold each of the Sellers and their
respective Affiliates and the respective officers, directors, employees, agents
and representatives of each of the foregoing (collectively, the "Seller
Indemnified Persons") harmless from and against any and all Losses incurred by
any Seller Indemnified Person arising out of or relating to, directly or
indirectly, (i) any breach of any representation or warranty of Wang in Article
IV this Agreement or (ii) any



                                       69


<PAGE>   74


breach of any covenant or agreement of Wang in this Agreement.

                  (b) Notwithstanding anything herein to the contrary: (i) Wang
shall have no obligation to indemnify any Seller Indemnified Person for Losses
pursuant to Section 6.2(a)(i) unless and until the aggregate amount of such
Losses exceeds $500,000, and then only to the extent such Losses exceed
$500,000; (ii) the aggregate liability of Wang pursuant to Section 6.2(a)(i) for
Losses incurred by Seller Indemnified Persons with respect to breaches of
representations and warranties in Sections 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 4.11
(the second sentence), 4.12 and 4.13 shall be limited to $3,331,500; (iii) the
aggregate liability of Wang pursuant to Section 6.2(a)(i) for Losses incurred by
Seller Indemnification Persons with respect to all breaches of representations
and warranties in Article IV shall be limited to $66,630,000.

            Section 6.3  CALCULATION OF LOSSES. For purposes of this Article VI,
(a) the amount of any Loss shall be calculated net of insurance proceeds
received by the indemnified party in connection with such Loss, (b) the amount
of any Loss shall be calculated taking into account any Tax benefit or detriment
actually realized, on a "with-or-without" basis, by the indemnifying party or
the indemnified party as a result of or in connection with either the matter,
event or condition giving rise to such Loss and (c) the amount of any Loss shall
be reduced to the extent such Loss was specifically identified and reserved
against (as to type of Loss and amount) on the Company Balance Sheet as adjusted
for the passage of time through the Closing Date in accordance with GAAP.

            Section 6.4  PROCEDURES RELATING TO INDEMNIFICATION. (a) An
indemnified party under this Article VI shall give prompt written notice to the
indemnifying party (when and to the extent that the indemnified party has actual
knowledge thereof) of any condition, event or occurrence or the commencement of
any action, suit or proceeding for which indemnification may be sought, and the
indemnifying party, through counsel of its own choosing and reasonably
satisfactory to the indemnified party, shall assume the defense thereof or other
indemnification obligation with respect thereto; PROVIDED, HOWEVER, that (i) any
indemnified party shall be entitled to partici-


                                       70


<PAGE>   75


pate in any such action, suit or proceeding with counsel of its own choice but
at its own expense and (ii) any indemnified party shall be entitled to
participate in any such action, suit or proceeding with counsel of its own
choice at the expense of the indemnifying party, if, in the good faith
determination of the indemnified party's counsel, representation by the
indemnifying party's counsel may present a conflict of interests. The failure of
any indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations under this Article VI, except to the
extent that the indemnifying party is actually prejudiced by such failure to
give notice. In any event, if the indemnifying party fails to assume the defense
within a reasonable time, the indemnified party may assume such defense or other
indemnification obligation and the reasonable fees and expenses of its attorneys
will be covered by the indemnity provided for in this Article VI. No action,
suit or proceeding for which indemnification may be sought shall be compromised
or settled in any manner which might materially and adversely affect the
interests of the indemnifying party without the prior written consent of such
indemnifying party (which shall not be unreasonably withheld). Notwithstanding
anything (other than Section 6.4(b)) in this Article VI to the contrary, the
indemnifying party shall not, without the written consent of the indemnified
party, (i) settle or compromise any action, suit or proceeding or consent to the
entry of any judgment which does not include as an unconditional term thereof
the delivery by the claimant or plaintiff to the indemnified party of a written
release from all liability in respect of such action, suit or proceeding or (ii)
settle or compromise any action, suit or proceeding in any manner that may
materially and adversely affect the indemnified party. The indemnifying party
shall pay all expenses, including attorneys' fees, that may be incurred by any
indemnified party in enforcing the indemnity provided for in this Article VI. If
the indemnifying party assumes the defense or settlement of any claim or demand,
the indemnified party will give the indemnifying party and its counsel
reasonable access to, during normal business hours, the business records and
other documents of the Company relating to such claim or demand, and shall
permit them to consult, during normal business hours, with employees of the
Company having information regarding such claim or demand.



                                       71


<PAGE>   76


Regardless of which person assumes the defense of any claim, each party shall
cooperate in the defense thereof.

                  (b) Notwithstanding anything in this Article VI to the
contrary, the Sellers, at their own expense, shall have the exclusive authority
to represent the Company before the IRS or any other governmental agency or
authority or before any court with respect to any matter affecting the Tax
liability of the Company for any Pre-Closing Date Period (not including the
Straddle Period) for which the Sellers might be obligated to indemnify the Wang
Indemnified Persons. Such representation shall include, but shall not be limited
to, exclusive control over (i) any response to any examination of any such Tax
Returns and (ii) any contest through a Final Determination of any issue included
in any such Tax Return, including, but not limited to, (A) whether and in what
forum to conduct such contest, and (B) whether and on what basis to settle such
contest; provided, however, that the Sellers shall not settle any contest if
such settlement would increase the Tax liability of Wang or the Company in any
period after the Closing Date without the consent of Wang or the Company, as the
case may be, which consent shall not be unreasonably withheld. Any Tax
controversy relating to the Company for a Straddle Period shall be controlled by
Wang, at its own expense; PROVIDED, HOWEVER, that Wang shall keep the Sellers
informed of all material developments relating to such controversy and the
Sellers, at their own expense, shall have the right to participate in (but not
control) the defense of any such controversy relating to any Tax Item subject to
indemnification pursuant to Section 6.1(c); PROVIDED, FURTHER, that Wang shall
not have the right to settle any Tax controversy to the extent such settlement
would increase the Sellers' indemnification obligation under Section 6.1(c)
without the consent of the Sellers, which consent shall not be unreasonably
withheld.

                  (c) Notwithstanding anything in this Agreement to the
contrary, the Sellers may appoint a representative (the "Sellers'
Representative") to act on their behalf pursuant to, and to follow the
procedures set forth in, this Section 6.4. If the Sellers appoint a Sellers'
Representative, so long as such appointment shall be in effect, Wang shall be
entitled, but shall under no circumstances be obligated, to deal exclusively
with the Sellers' Representative in respect of all mat-



                                       72


<PAGE>   77


ters under this Section 6.4, including, without limitation, the giving of all
notices pursuant to this Section 6.4. The Sellers hereby designate the authority
to Bajaj and the Goldman Stockholders to select the Sellers' Representative and
to provide written notice to Wang of such selection.

                  (d) The Sellers and Wang shall negotiate in good faith to
determine the amount of the Losses incurred by one party arising out of or
relating to, directly or indirectly, any breach of any representation, warranty,
covenant or agreement of the other party contained in this Agreement. If the
Sellers and Wang cannot agree to the amount of the Losses, the Sellers and Wang
shall settle their disagreement by arbitration in the City of New York, State of
New York, before three arbitrators in accordance with the then prevailing Rules
of Commercial Arbitration of the American Arbitration Association. Either Wang
or any Seller may initiate this procedure by so informing the other parties. The
date of such communication shall be deemed to be the time the disagreement arose
(the "Disagreement Date"). The Sellers shall select one arbitrator. Wang shall
select one arbitrator. The two arbitrators so selected shall select a third
arbitrator. If one party has not selected its arbitrator within 20 days of the
Disagreement Date, or if the two arbitrators so selected have not selected a
third arbitrator within 40 days of the Disagreement Date, the one arbitrator or
the two arbitrators, as the case may be, shall apply for the appointment of a
second or third arbitrator, as the case may be, by a justice then sitting in a
special term part of the Supreme Court of the State of New York: New York
County. If the three arbitrators have not addressed and resolved any such
disagreements within 180 days of the Disagreement Date, the parties shall be
entitled to their remedies at law or in equity, if any, and any such
disagreements shall not then be resolved by arbitration under this Section
6.4(d). Judgment upon the award rendered by the arbitrators may be entered in
any court having jurisdiction. The cost of arbitration shall be borne one-half
by Wang and one-half by the Sellers participating therein in proportion to their
respective percentage of the aggregate consideration received pursuant to this
Agreement by the Sellers participating therein as set forth in Exhibit A hereto.

            Section 6.5  TERMINATION OF INDEMNIFICATION. No indemnified party
under this Article VI shall be entitled to indemnification under this Article VI
with respect to any breach of any representation or warranty or covenant or
agreement after the termination thereof pursuant to Section 8.10, except for
breaches with respect to which notice was given to the indemnifying party
pursuant to Section 6.4 prior to termination of the representation or warranty
or covenant or agreement to which it relates.

            Section 6.6  CONSIDERATION FOR PAYMENT OF INDEMNIFICATION
OBLIGATIONS; RIGHT OF SET-OFF. With respect to any indemnification obligation
under this Article VI, such obligation shall be satisfied by means of a payment
in cash by the indemnifying party to the applicable indemnified party in an
amount equal to the Loss incurred by such indemnified party; provided, however,
that: (a) Wang may, at its option and in addition to any other rights it may
have, offset any Loss incurred by any Wang Indemnified Person against the
principal amount of any Note held by any Seller obligated to indemnify such Wang
Indemnified Person against such Loss and such Seller's obligation shall be
satisfied to, and only to, the extent of such offset; and (b) any Seller
obligated to indemnify any Wang Indemnified Person for any Loss may elect, by
written notice to Wang, to have Wang offset such Loss against the principal
amount of any Note held by such Seller and such Seller's obligation shall be
satisfied to, and only to, the extent of such offset.

            Section 6. 7 EXCLUSIVE REMEDY. If the transactions contemplated by
this Agreement are consummated, the indemnification provisions of this Article
VI shall be the sole and exclusive remedy of the parties against one another
with respect to any Loss under this Agreement.

                  (b) by Bajaj and the Goldman Stockholders, on behalf of all of

                  (d) by Bajaj and the Goldman Stockholders, on behalf of all of
the Sellers, on the one hand, or Wang, on the other hand, if any court of
competent jurisdiction in the United States or other United States governmental
body shall have issued an order, decree or ruling or taken any other action
restraining, enjoining or otherwise prohibiting the transactions contemplated
hereby and such order, decree, ruling or other action shall have become final
and nonappealable.

            Section 8.2  EFFECT OF TERMINATION. In the event this Agreement is
validly terminated pursuant to Section 8.1 hereof, this Agreement will forthwith

hereunder except as provided in the next succeeding sentence and except that the
provisions of Section 5.7 will continue to apply following any such termination.
Notwithstanding the foregoing, a party will remain liable to the other parties
hereto if such termination was the result of such party's willful breach of this
Agreement or such party's fraud, bad faith or willful misconduct.

            Section 8.3  SEVERABILITY. If any provision of this Agreement is 
held to be illegal, invalid or unenforceable by any court or governmental agency
or with competent jurisdiction, and if the rights or obligations of any party
hereto under this Agreement will not be materially and adversely affected
thereby, (i) such provision will be fully severable, (ii) this Agreement will be
construed and enforced as if such illegal, invalid or unenforceable provision
had never comprised a part hereof, (iii) the remaining provisions of this
Agreement will remain in full force and effect and will not be affected by the
illegal, invalid or unenforceable provision or by its severance herefrom and
(iv) in lieu of such illegal, invalid or unenforceable provision, there will be
added automatically as a part of this Agreement a legal, valid and enforceable
provision as similar in terms to such illegal, invalid or unenforceable
provision as may be possible.

            Section 8.4  ENTIRE AGREEMENT. This Agreement (together with the
documents attached as exhibits hereto and any documents or agreements
specifically contemplated hereby) supersedes all prior discussions and
agreements

more counterparts, all of which shall be considered one and the same agreement,

any claim that any such action, suit or proceeding brought in such a court has
been brought in an inconvenient forum. Nothing herein shall affect the right of

legal proceedings or otherwise proceed against the other parties in any other
jurisdiction.

                 AMENDMENT NO. 1 TO THE STOCK PURCHASE AGREEMENT


            THIS AMENDMENT NO. 1 TO THE STOCK PURCHASE AGREEMENT (this
"Amendment No. 1 to the Stock Purchase Agreement") is being entered into as of
August 29, 1996 by and among Wang Laboratories, Inc., a Delaware corporation
("Wang"), and the other signatories hereto (the "Sellers").

            WHEREAS, Wang and the Sellers are parties to a Stock Purchase
Agreement, dated as of July 24, 1996 (the "Stock Purchase Agreement"), pursuant
to which Wang has agreed to purchase from the Sellers, and the Sellers have
agreed to sell to Wang, all of the issued and outstanding shares of capital
stock of I-NET, Inc., a Maryland corporation (the "Company"), owned by the
Sellers;

            WHEREAS, by letter dated August 19, 1996 attached as Exhibit A
hereto (the "Sellers' Letter"), the Sellers gave Wang notice of certain events
or conditions which have occurred since the date of the Stock Purchase
Agreement;

            WHEREAS, by letter dated August 23, 1996 attached as Exhibit B
hereto ("Wang's Letter"), Wang responded to the Sellers' Letter;

            WHEREAS, Wang and the Sellers desire to resolve the matters at issue
in the Sellers' Letter and Wang's Letter so that they can, simultaneously with
such resolution, consummate the transactions contemplated by the Stock
Purchase Agreement; and

            WHEREAS, Wang and the Sellers are entering into this Amendment No. 1
to the Stock Purchase Agreement to resolve the matters at issue in the Sellers'
Letter and Wang's Letter;

            NOW, THEREFORE, in consideration of the foregoing, the mutual
covenants contained herein and the consummation of the transactions
contemplated by the Stock Purchase Agreement, Wang and the Sellers agree to
amend the Stock Purchase Agreement as follows (with capitalized terms used and
not defined herein having their respective meanings set forth in the Stock
Purchase Agreement):


 
<PAGE>   93

            Section 1. ADJUSTMENT OF NOTES. To resolve the write-off of $742,000
on the ArPerCen contract disclosed in paragraph 3 of the Sellers' Letter (the
"ArPerCen Write-Off"), the operating reserve of $900,000 with respect to the CIT
equipment lease costs disclosed in paragraph 4 of the Sellers' Letter (the "CIT
Reserve") and the write-off of $460,000 of obsolete equipment having no future
economic usefulness disclosed in paragraph 5 of the Sellers' Letter (the
"Equipment Write-Off"), the aggregate principal amount of the Note or Notes to
be delivered at the Closing by Wang to each Seller pursuant to Section
2.3(a)(ii)(y) of the Stock Purchase Agreement shall be reduced by the amount set
forth under the heading "Adjustment for Certain Write-Offs and Reserves"
opposite such Seller's name on Exhibit C hereto.

            Section 2. ADDITIONAL SELLER INDEMNIFICATION; COMMERCIALLY
REASONABLE BEST EFFORTS TO RECOVER RESERVES. (a) To resolve the reserve of
$962,000 on the FAA contract disclosed in paragraph 3 of the Sellers' Letter
(the "FAA Reserve") and the reserve of $360,000 on undepreciated cost of
equipment in use disclosed in paragraph 5 of the Sellers' Letter (the "Equipment
Reserve"), the Sellers, subject to this Section 2(a), will indemnify and hold
the Wang Indemnified Persons harmless from and against (i) the amount, if any,
of the FAA Reserve not determined by the Company, in the ordinary course of
business consistent with past practice and on or prior to May 15, 1997, to be
unnecessary (and thus reversed) through improved operational effectiveness,
contract modifications or other steps or to be unnecessary (and thus reversed)
for any other reason (and such amount shall be a Loss within the meaning of the
Stock Purchase Agreement) or (ii) the amount, if any, of the Equipment Reserve
not determined by the Company, in the ordinary course of business consistent
with past practice and on or prior to May 15, 1997, to be unnecessary (and thus
reversed) through use of the related assets in imaging contracts or to be
unnecessary (and thus reversed) for any other reason (and such amount shall be
a Loss within the meaning of the Stock Purchase Agreement); provided, however,
that the Sellers will not have any obligation to indemnify the Wang Indemnified
Persons for Losses pursuant to this Section 2(a) unless and until the aggregate
amount of such Losses exceeds $322,000; provided, further, however, that if
the aggregate amount of such Losses exceeds $322,000, the immediately preceding
proviso shall be disregarded and the Sellers, subject to this Section 2(a), will
indemnify the Wang Indemnified Persons for all of such Losses. Article VI of the
Stock Purchase Agreement shall apply to the indemnification

 
                                        2
<PAGE>   94

provided for in this Section 2(a), and, among other things, the indemnification
provided for in this Section 2(a) shall be considered an obligation of the
Sellers under Section 6.1(a)(i) of the Stock Purchase Agreement with respect to
breaches of representations and warranties in Section 3.7 of the Stock
Purchase Agreement for purposes of the application of Section 6.1(b) of the
Stock Purchase Agreement and any Losses with respect to which the Wang
Indemnified Persons are entitled to be indemnified pursuant to this Section 2(a)
shall be considered Losses incurred by the Wang Indemnified Persons with
respect to breaches of representations and warranties in Section 3.7 of the
Stock Purchase Agreement for purposes of the application of Section 6.1(b) of
the Stock Purchase Agreement.

                    (b) Until May 15, 1997, Wang shall cause the Company to use 
its commercially reasonable best efforts to recover (x) the FAA Reserve through
improved operational effectiveness, contract modifications or other steps and
(y) the Equipment Reserve through use of the related assets in imaging
contracts.

            Section 3.  ADJUSTMENT OF INDEMNIFICATION CAPS. The amount of
$8,333,150 appearing in three places in clause (ii) of the fourth sentence of
Section 6.1(b) of the Stock Purchase Agreement is hereby amended to be
$8,250,550 in each such place. The amount of $41,657,500 appearing in clause
(iii) of the fourth sentence of Section 6.1(b) of the Stock Purchase Agreement
is hereby amended to be $41,574,900. The amount of $166,630,000 appearing in
clauses (iv) and (v) of the fourth sentence of Section 6.1(b) of the Stock
Purchase Agreement is hereby amended to be $166,547,400. The amount of
$3,331,500 appearing in clause (ii) of Section 6.2(b) of the Stock Purchase
Agreement is hereby amended to be $3,248,900. The amount of $66,630,000
appearing in clause (iii) of Section 6.2(b) of the Stock Purchase Agreement is
hereby amended to be $66,547,400.

            Section 4. CALCULATION OF LOSSES. The amount of any Losses incurred
by any Wang Indemnified Person shall not be reduced pursuant to Section 6.3(c)
of the Stock Purchase Agreement by the amount of the ArPerCen Write-Off, the CIT
Reserve, the Equipment Write-Off, the FAA Reserve or the Equipment Reserve.

            Section 5. NO ADMISSION. The Sellers' execution and delivery of
this Amendment No. 1 to the Stock Purchase Agreement shall not be construed as
an admission that the events or conditions disclosed in the Sellers' Letter,
individually or in the aggregate, constituted a

 
                                        3
<PAGE>   95

breach of any representation or warranty or covenant or agreement of any Seller
in the Stock Purchase Agreement.

            Section 6.  NO WAIVER. Wang's execution and delivery of this
Amendment No. 1 to the Stock Purchase Agreement shall not be construed as a
waiver, and Wang hereby reserves its rights with respect to, any other
write-offs, reserves or other changes or events relating to the ArPerCen
contract, the FAA contract, the CIT equipment lease or assets of the Company
other than the equipment the subject of the Equipment Write-Off or the Equipment
Reserve.

            Section 7.  CLOSING CERTIFICATES. Because the events or conditions
disclosed in the Sellers' Letter have been resolved in this Amendment No. 1 to
the Stock Purchase Agreement, neither the exception taken with respect to the
Sellers' Letter in the certificates of each of the Sellers being delivered to
Wang at the Closing pursuant to Section 7.1(a) of the Stock Purchase Agreement
or in the certificate of the Company's chief financial officer being delivered
to Wang at the Closing pursuant to Section 7.1(l) of the Stock Purchase 
Agreement, nor Wang's acceptance of such certificates with such exception, shall
have any effect on the rights or obligations of the parties to the Stock
Purchase Agreements after the Closing, except as provided in this Amendment
No. 1 to the Stock Purchase Agreement.

            Section 8.  SCOPE OF THIS AMENDMENT NO. 1 TO THE STOCK PURCHASE
AGREEMENT. Except as expressly provided in this Amendment No. 1 to the Stock
Purchase Agreement, the Stock Purchase Agreement shall remain in full force and
effect.

            Section 9.  CLOSING DOCUMENTS. All references to the Stock Purchase
Agreement in the documents being delivered at the Closing shall be deemed to be
to the Stock Purchase Agreement as amended by this Amendment No. 1 to the Stock
Purchase Agreement.

shall give each Lender prompt notice by telephone or facsimile transmission of a
Notice of Borrowing that requests Lender Advances of Revolving Loans. No later

reflected in the Notice of Borrowing, each Lender shall make available to the
Agent at the Agent's address such Lender's Proportionate Share of such borrowing

notice prior to the date of any such borrowing of Revolving Loans, it is
entitled to assume that each Lender will make available its Proportionate Share
of the borrowing and in reliance upon that assumption, but without any
obligation to do so, may advance such Proportionate Share on behalf of such
Lender.

by the Agent as of 5:00 p.m. (New York City time) on the last Business Day of
the period specified by the Agent (such date, the "SETTLEMENT DATE").

                    (b) SUMMARY STATEMENTS; SETTLEMENTS OF PRINCIPAL. The Agent
shall deliver to each of the Lenders promptly after the Settlement Date a
summary statement of the amount of outstanding Revolving Loans (including Agent
Advances). As reflected on the summary statement: (i) the Agent shall transfer
to each Lender its Proportionate Share of repayments; and (ii) each Lender shall
transfer to the Agent, or the Agent shall transfer to each Lender, such amounts
as are necessary to insure that, after giving effect to all such transfers, the
amount of Revolving Loans made by each Lender shall be equal to such Lender's
Proportionate Share of the aggregate amount of Revolving Loans outstanding as of
such Settlement Date. If the summary statement requires transfers to be made to
the Agent by the Lenders and is received prior to 12:00 Noon (New York City
time) on a Business Day, such transfers shall be made in immediately available
funds no later than 3:00 p.m. (New York City time) that day; and, if received
after 12:00 Noon (New York City time), then no later than 3:00 p.m. (New York
City time) on the next Business Day. The obligation of each Lender to transfer
such funds is irrevocable, unconditional and without recourse to or warranty by
the Agent.

                    (c) DISTRIBUTION OF INTEREST AND UNUSED LINE FEES. Interest
on the Revolving Loans (including Agent Advances) shall be allocated by the
Agent to each Lender in accordance with the Proportionate Share of Revolving
Loans actually advanced by and repaid to each Lender, and shall accrue from and
including the date such Revolving Loans are so advanced and to but excluding the
date such Revolving Loans are either repaid by the Borrowers or actually settled
under this Section. The Unused Line Fee shall be allocated by the Agent to each
Lender in accordance with such Lender's Proportionate Share of such Fee,
regardless of the amount of Revolving Loans actually advanced by such Lender.
After the end of each month, the Agent shall, upon receipt from the Borrowers,
distribute to each Lender its Proportionate Share of the interest and Unused
Line Fee accrued during such month. The Agent shall, upon receipt from the
Borrowers, distribute interest on Eurodollar Rate Loans promptly after it is
received from the Borrowers.

                  SECTION 2.7. SHARING OF PAYMENTS. If any Lender shall obtain
any payment pursuant to the terms of this Credit Agreement (whether voluntary,
involuntary, through the exercise of any right of setoff or otherwise) on
account of the Loans made by it or its participation in Letters of Credit in
excess of its Proportionate Share of payments on account of the Loans or Letters
of Credit obtained by all the Lenders, such Lender shall forthwith purchase from
the other Lenders such participations in the Loans made by them or in their
participation in Letters of Credit as shall be necessary to cause such
purchasing Lender to share the excess payment ratably with each of them;
PROVIDED, HOWEVER, that if all or any portion of such excess payment is

                                      -36-


<PAGE>   43




thereafter recovered from such purchasing Lender, such purchase from each Lender
shall be rescinded and each such Lender shall repay to the purchasing Lender the
purchase price to the extent of such recovery together with an amount equal to
such Lender's ratable share (according to the proportion of (i) the amount of
such Lender's required repayment to (ii) the total amount so recovered from the
purchasing Lender) of any interest or other amount paid or payable by the
purchasing Lender in respect to the total amount so recovered, and PROVIDED,
FURTHER that this Section shall not apply with respect to any fees which are
intended to be for the benefit of less than all of the Lenders. The Borrowers
agree that any Lender so purchasing a participation from another Lender pursuant
to this Section 2.7 may, to the fullest extent permitted by law, exercise all of
its rights of payment (including the right of setoff) with respect to such
participation as fully as if such Lender were the direct creditor of the
Borrowers in the amount of such participation. Notwithstanding anything
contained herein to the contrary, the sharing provisions of this Section 2.7
shall not apply to any payments received by any Lender from or on behalf of the
Borrowers or the Agent that are not made pursuant to the express terms and
provisions of this Credit Agreement.

                  SECTION 2.8.  DEFAULTING LENDERS.

                    (a) A Lender who fails to pay the Agent its Proportionate
Share of any Revolving Loans (including Agent Advances) made available by the
Agent on such Lender's behalf, or who fails to pay any other amount owing by it
to the Agent, is a defaulting lender ("DEFAULTING LENDER"). The Agent may
recover all such amounts owing by a Defaulting Lender on demand. If the
Defaulting Lender does not pay such amounts on the Agent's demand, the Agent
shall promptly notify the Borrowers and the Borrowers shall pay such amounts
with respect to Revolving Loans within five Business Days. In addition, the
Defaulting Lender or the Borrowers shall pay the Agent interest on such amount
for each day from the date it was made available by the Agent to Wang to the
date it is recovered by the Agent at a rate PER ANNUM equal to (x) the overnight
Federal Funds Rate, if paid by the Defaulting Lender, or (y) the then applicable
rate of interest calculated under Section 4.1, if paid by the Borrowers; plus,
in each case, the Expenses and losses, if any, incurred as a result of the
Defaulting Lender's failure to perform its obligations.

                    (b) The failure of any Lender to fund its Proportionate
Share of any Revolving Loan (including Agent Advances) shall not relieve any
other Lender of its obligation to fund its Proportionate Share of such Revolving
Loan. Conversely, no Lender shall be responsible for the failure of another
Lender to fund such other Lender's Proportionate Share of a Revolving Loan.

<PAGE>   44




                    (c) The Agent shall not be obligated to transfer to a
Defaulting Lender any payments made by a Borrower to the Agent for the
Defaulting Lender's benefit; nor shall a Defaulting Lender be entitled to the
sharing of any payments hereunder. Amounts payable to a Defaulting Lender shall
instead be paid to or retained by the Agent. The Agent may hold and, in its
discretion, re-lend to Wang the amount of all such payments received or retained
by it for the account of such Defaulting Lender. For purposes of the Unused Line
Fee and for voting or consenting to matters with respect to the Credit Documents
and determining Proportionate Shares, such Defaulting Lender shall be deemed not
to be a "Lender" and such Lender's Commitment shall be deemed to be zero (-0-).
This Section shall remain effective with respect to such Lender until the
Defaulting Lender has paid all amounts required to be paid to the Agent
hereunder or until the Majority Lenders, the Agent and the Borrowers shall have
waived such Lender's default in writing or such default has been cured. The
operation of this Section shall not be construed to increase or otherwise affect
the Commitment of any Lender, or relieve or excuse the performance by the
Borrowers of their duties and obligations hereunder.

                  SECTION 2.9.  MANDATORY AND VOLUNTARY PAYMENT; MANDATORY AND 
VOLUNTARY REDUCTION OF COMMITMENTS.

                    (a) The aggregate balance of Revolving Loans and all Letter
of Credit Obligations outstanding at any time in excess of the lesser of (i) the
Borrowing Base then in effect and (ii) the Line of Credit shall be immediately
due and payable without the necessity of any demand; PROVIDED, HOWEVER that if
the aggregate balance of Revolving Loans and all Letter of Credit Obligations
exceeds the Borrowing Base solely due to a change in the Borrowing Base made by
the Agent pursuant to the terms of this Credit Agreement, the amount in excess
of the Borrowing Base shall be due and payable five (5) Business Days after
notice from the Agent.

                    (b) Wang may reduce or terminate the Commitments on a PRO
RATA basis at any time and from time to time in whole or in part; PROVIDED,
HOWEVER, that each such reduction must be in an aggregate amount for all Lenders
of not less than $5,000,000 (and in increments of $1,000,000 thereafter). Once
reduced, no portion of the Commitments may be reinstated.

                    (c) The Line of Credit shall be permanently and
automatically reduced to $200,000,000 on March 31, 1998, (ii) $175,000,000 on
September 30, 1998 and (iii) $150,000,000 on March 31, 1999. Such reductions
shall reduce the Commitment of each Lender proportionately by its Proportionate
Share of the amount of such reductions.

                    (d) All Net Cash Proceeds from the consummation of an Asset
Sale or from the issuance of any equity securities, and Litigation Proceeds
shall be immediately paid to the Agent to be applied to repay the outstanding
Revolving Loans. All amounts applied to repay the outstanding Revolving Loans
under this Section 2.9(d) may be reborrowed, subject to the terms and conditions
contained herein.

                  SECTION 2.10. MAINTENANCE OF LOAN ACCOUNT; STATEMENTS OF
ACCOUNT. The Agent shall maintain an account on its books in the name of Wang
(the "LOAN ACCOUNT") in which Wang will be charged with all loans and advances
made by the Lenders to Wang or for Wang's account, including the Revolving
Loans, the Letter of Credit Obligations, the Fees, the Expenses and any other
Obligations. The Loan Account will be credited with all amounts received by the
Agent from the Borrowers or for the Borrowers' account, including, as set forth
in Section 2.12, all amounts received in the Concentration Accounts from any
Lockbox Bank. The Agent shall send the Borrowers a monthly statement reflecting
the activity in the Loan Account. Absent manifest error, each monthly statement
shall be an account stated and shall be final, conclusive and binding on the
Borrowers.

                  SECTION 2.11. PAYMENT PROCEDURES. The Borrowers hereby
authorize the Agent to charge the Loan Account with the amount of all interest,
Fees and Expenses and other payments to be made hereunder and under the other
Credit Documents. The Borrowers' obligations to the Agent and the Lenders with
respect to such payments shall be discharged by the Agent's charging the Loan
Account as provided herein.

                  SECTION 2.12. COLLECTIONS.

                    (a) Wang and Wang Canada shall at all times maintain
lockboxes (the "LOCKBOXES") and shall instruct all account debtors on their
Accounts to remit all Collections to their respective Lockboxes. Such Borrowers
shall enter into agreements with the Agent and financial institutions acceptable
to the Agent (the "LOCKBOX BANKS") substantially in the form of Exhibit L to the
Existing Credit Agreement (the "LOCKBOX AGREEMENTS"), which among other things
shall provide for the opening of an account with such Lockbox Bank for the
deposit of Collections (a "COLLECTION ACCOUNT") and shall require the Agent's
consent to its termination (except on the Expiration Date). All Collections and
other amounts received by such Borrowers from any account debtor shall upon
receipt be deposited into a Collection Account maintained by such Borrowers.
Upon the terms and subject to the conditions set forth in the Lockbox
Agreements, all available amounts held in each Collection Account shall be wired
each Business Day into an account (a "CONCENTRATION ACCOUNT") maintained by the
Agent at a financial institution acceptable to the Borrowers and the Agent (a
"CONCENTRATION BANK"). Such

                                      -39-


<PAGE>   46




Borrowers shall enter into one or more agreements with a Concentration Bank and
the Agent substantially in the form of Exhibit N to the Existing Credit
Agreement (the "CONCENTRATION ACCOUNT AGREEMENTS"). All amounts other than
Collections received by the Borrowers from any source shall upon receipt be
deposited into a separate Concentration Account maintained by the Agent at a
Concentration Bank. Upon the terms and subject to the conditions set forth in
the Concentration Account Agreements, all available amounts held in each
Concentration Account shall be wired each Business Day into an account
maintained by the Agent at Bankers Trust Company (the "BT ACCOUNT").

                    (b) WFI, INET and, subject to Section 7.1(t)(i), Dataserv
shall at all times maintain a Lockbox with a Lockbox Bank pursuant to a Lockbox
Agreement and shall instruct all account debtors on the Accounts to remit all
Collections to such Lockbox. All Collections and other amounts received by such
Borrowers from any account debtor shall upon receipt be deposited into a
Collection Account. Upon the terms and subject to the conditions set forth in
the Lockbox Agreements, all available amounts held in the Collection Accounts
shall be wired each Business Day into the BT Account. All amounts other than
Collections received by such Borrowers from any source shall upon receipt be
deposited into a separate Concentration Account maintained by the Agent at a
Concentration Bank. Until Dataserv complies with the provisions of Section
7.1(t)(i), Dataserv shall deposit all Collections and other amounts received by
Dataserv from any account debtor into a Collection Account maintained by Wang
promptly upon receipt.

                    (c) Wang shall cause Wang Software at all times to maintain
a bank account (the "WANG SOFTWARE DEPOSITARY ACCOUNT") with Chemical Bank or
any other bank acceptable to the Agent (the "DEPOSITARY ACCOUNT BANK"). Wang
shall cause Wang Software to enter into an agreement with the Agent and the
Depositary Account Bank, in form and substance satisfactory to the Agent (as
amended, supplemented or otherwise modified from time to time, the "WANG
SOFTWARE DEPOSITARY ACCOUNT AGREEMENT"), which among other things shall provide
for the opening of the Wang Software Depositary Account for the deposit of Wang
Software's Collections and shall require the Agent's consent to its termination
(except on the Expiration Date). Wang shall cause Wang Software to deposit all
Collections and other amounts received by Wang Software from any account debtor
into the Wang Software Depositary Account promptly upon receipt. Subject to the
terms and conditions set forth in the Wang Software Depositary Account
Agreement, upon and after the time the Depositary Account Bank shall have
received a Notice of Redirection (as defined in the Wang Software Depositary
Account Agreement) from the Agent, all amounts deposited in the Wang Software
Depositary Account shall be transferred only as provided by the Agent in such
Notice of Redirection.

                    (d) Promptly upon the written request of the Agent, Wang
shall cause WSSM to deposit all Collections and other amounts received by WSSM
from any account debtor into a Collection Account maintained by Wang promptly
upon receipt.

                  SECTION 2.13. APPLICATION OF PAYMENTS. All amounts received in
the BT Account shall be credited to the Loan Account as of the date received.
Except as provided in Section 8.5, after the occurrence of an Event of Default,
and until it is waived, all amounts received by the Agent from the Lockbox
Banks, from the Concentration Accounts, from liquidation of Collateral or
otherwise, shall be applied in the following order: FIRST, to the payment of any
Fees, Expenses or other Obligations due and payable to the Agent or the
Collateral Agent under any of the Credit Documents, including Agent Advances and
any other amounts advanced by the Agent on behalf of the Lenders; SECOND, to the
payment of any Fees, Expenses or other Obligations due and payable to the
Issuing Bank under any of the Credit Documents; THIRD, to the ratable payment of
any Fees, Expenses or other Obligations due and payable to the Lenders under any
of the Credit Documents other than those Obligations specifically referred to in
this Section; FOURTH, to the ratable payment of interest due on the Revolving
Loans; FIFTH, to the ratable payment of principal due on the Revolving Loans;
SIXTH to cash collateralize Letters of Credit in accordance with the provisions
of Section 8.2(c); and SEVENTH, if no Obligations are outstanding, to the
Borrowers. Any amounts received in the BT Account after this Credit Agreement
has terminated, all Obligations have been indefeasibly paid in full and all
outstanding Letters of Credit have been cash collateralized in an amount equal
to 105% of the aggregate face amount thereof shall be delivered to Wang.

                                LETTERS OF CREDIT

                  SECTION 3.1. ISSUANCE OF LETTERS OF CREDIT. Subject to the
terms and conditions of this Credit Agreement and in reliance upon the
representations and warranties of the Borrowers set forth herein, the Issuing
Bank shall issue Letters of Credit hereunder at the request of Wang and for the
account of Wang or, if approved by the Agent, one of Wang's Subsidiaries, as
more specifically described below. The Issuing Bank shall not be obligated to
issue any Letter of Credit for the account of Wang or any such Subsidiary on or
after the Expiration Date. The Issuing Bank shall not (in the case of clause (a)
below) and shall not be obligated to (in the case of clauses (b) and (c) below)
issue any Letter of Credit for the account of Wang or any such Subsidiary if at
the time of such requested issuance:

                                      -41-


<PAGE>   48




                    (a) The face amount of such requested Letter of Credit when
added to the Letter of Credit Obligations then outstanding, would cause the
Letter of Credit Obligations to exceed (i) $70,000,000 or (ii) when added to the
aggregate amount of Revolving Loans and all Letter of Credit Obligations then
outstanding would cause the sum of the Revolving Loans and Letter of Credit
Obligations to exceed the lesser of (x) the Line of Credit and (y) the Borrowing
Base then in effect; PROVIDED, HOWEVER that in no event shall the aggregate
amount of Revolving Loans made and Letters of Credit issued in respect of
Eligible Accounts Receivable consisting of Unbilled Accounts exceed the lesser
of 10% of all Accounts of WFI that do not consist of Unbilled Accounts and
$10,000,000; PROVIDED, FURTHER that no Letter of Credit shall be issued if the
issuance thereof would cause the face amount of all Letter of Credit Obligations
then outstanding on account of documentary letters of credit to exceed
$40,000,000; or

                    (b) Any order, judgment or decree of any Governmental
Authority or arbitrator shall purport by its terms to enjoin or restrain the
Issuing Bank from issuing such Letter of Credit or any Requirement of Law
applicable to the Issuing Bank or any request or directive (whether or not
having the force of law) from any Governmental Authority with jurisdiction over
the Issuing Bank shall prohibit, or request the Issuing Bank refrain from, the
issuance of letters of credit generally or such Letter of Credit in particular
or shall impose upon the Issuing Bank with respect to such Letter of Credit any
restriction or reserve or capital requirement (for which the Issuing Bank is not
otherwise compensated) not in effect as of the Closing Date, or any unreimbursed
loss, cost or expense which was not applicable, in effect or known to the
Issuing Bank as of the Closing Date and which the Issuing Bank deems in good
faith to be material to it; or

                    (c) A default of any Lender's obligations to fund under
Section 3.6 exists, or such Lender is a Defaulting Lender, unless the Agent and
the Issuing Bank have entered into satisfactory arrangements with the Borrowers
to eliminate the Issuing Bank's risk with respect to such Lender, including cash
collateralization of such Lender's Proportionate Share of the Letter of Credit
Obligations.

                  SECTION 3.2. TERMS OF LETTERS OF CREDIT. The Letters of Credit
shall be in a form customarily used by the Issuing Bank or in such other form as
has been approved by the Issuing Bank. At the time of issuance, the amount and
the terms and conditions of each Letter of Credit, and of any drafts or
acceptances thereunder, shall be subject to approval by the Agent and Wang. In
no event may the term of any Letter of Credit issued hereunder exceed 365/366
days (except that such Letters of Credit may

                                      -42-


<PAGE>   49



provide for annual renewal) and all Letters of Credit issued hereunder shall
expire no later than the date that is five (5) Business Days prior to the
Expiration Date. Any Letter of Credit containing an automatic renewal provision
(other than a Letter of Credit issued with respect to worker's compensation
insurance or a Letter of Credit listed on Schedule 3.2) shall also contain a
provision pursuant to which, notwithstanding any other provisions thereof, it
shall not be renewable on or after the Expiration Date and it shall expire no
later than the date that is three (3) Business Days prior to the Expiration
Date. Notwithstanding the foregoing, a Letter of Credit may have an expiry date
subsequent to the Expiration Date if, on or prior to the Expiration Date, such
Letter of Credit is cash collateralized in a manner satisfactory to the Agent
and in an amount equal to 105% of the aggregate face amount thereof or is
supported by another letter of credit which is issued by a financial institution
reasonably acceptable to the Agent and is in a form and contains terms and
conditions reasonably satisfactory to the Agent.

                  SECTION 3.3. LENDERS' PARTICIPATION. Immediately upon issuance
or amendment by the Issuing Bank of any Letter of Credit in accordance with the
procedures set forth in Sections 3.1 and 3.2, each Lender shall be deemed to
have irrevocably and unconditionally purchased and received from the Issuing
Bank, without recourse or warranty, an undivided interest and participation to
the extent of such Lender's Proportionate Share (based upon its Commitment) of
the liability with respect to such Letter of Credit (including, without
limitation, all obligations of the Borrowers with respect thereto, other than
amounts owing to the Issuing Bank consisting of Issuing Bank Fees) and any
security therefor or guaranty pertaining thereto.

                  SECTION 3.4. NOTICE OF ISSUANCE. Whenever Wang desires the
issuance of a Letter of Credit, Wang shall deliver to the Agent a written notice
no later than 1:00 p.m. New York City time at least three (3) Business Days (or
such shorter period as may be agreed to by the Issuing Bank) in advance of the
proposed date of issuance of a letter of credit request in substantially the
form attached as Exhibit F (a "LETTER OF CREDIT REQUEST") accompanied by such
application and agreement for letter of credit (a "LETTER OF CREDIT AGREEMENT")
as the Issuing Bank may specify to Wang in connection with such requested Letter
of Credit. The transmittal by Wang of each Letter of Credit Request shall be
deemed to be a representation and warranty by the Borrowers that the Letter of
Credit may be issued in accordance with and will not violate any of the
requirements of Sections 3.1 and 3.2. Prior to the date of issuance of each
Letter of Credit, Wang shall provide to the Agent a precise description of the
documents and the text of any certificate to be presented by the beneficiary of
such Letter of Credit which if presented by such beneficiary on or prior to the
expiration date of the Letter of Credit would require the Issuing Bank to make
payment under the

                                      -43-


<PAGE>   50




Letter of Credit. The Issuing Bank, in its reasonable judgment, may require
changes in any such documents and certificates. No Letter of Credit shall
require payment against a conforming draft to be made thereunder prior to the
second Business Day (under the laws of the jurisdiction of the Issuing Bank)
after the date on which such draft is presented. A Letter of Credit Request may
be given in writing or electronically and, if requested by the Agent, with
prompt confirmation in writing. Any electronic Letter of Credit Request shall be
deemed to have been prepared by, or under the supervision of the chief financial
officer or other Authorized Officer of Wang. The Agent shall promptly provide
the aforementioned Letter of Credit Request, document description and proposed
text of certification to the Issuing Bank.

                  SECTION 3.5. PAYMENT OF AMOUNT DRAWN UNDER LETTERS OF CREDIT.
In the event of any request for drawing under any Letter of Credit by the
beneficiary thereof, the Issuing Bank shall notify the Agent, which shall notify
the Borrowers of such request, not later than 11:00 a.m. (New York City time) on
the Business Day immediately prior to the date on which the Issuing Bank intends
to honor such drawing. The Borrowers shall give notice to be received by the
Agent and the Issuing Bank not later than 2:00 p.m. (New York City time) on such
Business Day if they intend to reimburse the Issuing Bank for the amount of such
drawing with funds other than the proceeds of Loans. Such notice from the
Borrowers shall be irrevocable and, if given, the Borrowers, jointly and
severally, shall reimburse the Issuing Bank not later than the close of business
(New York City time) on the day on which such drawing is honored in an amount in
same day funds equal to the amount of such drawing. If the Agent shall not have
timely received such notice (i) the Borrowers shall be deemed to have timely
given a Notice of Borrowing to the Agent to make Loans on the date on which such
drawing is honored in an amount equal to the amount of such drawing and (ii)
subject to satisfaction or waiver of the applicable conditions specified in
Article V and the other terms and conditions of Borrowings contained herein, the
Lenders shall, on the date of such drawing, make Loans in the amount of such
drawing, the proceeds of which shall be applied directly by the Agent to
reimburse the Issuing Bank for the amount of such drawing or payment. If for any
reason, proceeds of Loans are not received by the Issuing Bank on such date in
an amount equal to the amount of such drawing, the Borrowers shall be obligated
to and shall reimburse the Issuing Bank, on the Business Day (under the laws of
the jurisdiction of the Issuing Bank) immediately following the date of such
drawing, in an amount in same day funds equal to the excess of the amount of
such drawing over the amount of such Loans, if any, which are so received, plus
accrued interest on such amount at the rate set forth in Section 4.1.

                                      -44-


<PAGE>   51



                  SECTION 3.6. PAYMENT BY LENDERS. In the event that the
Borrowers do not reimburse the Issuing Bank for the amount of any drawing
pursuant to Section 3.5, the Agent shall promptly notify each Lender of the
unreimbursed amount of such drawing and of such Lender's respective
participation therein. Each Lender shall make available to the Issuing Bank an
amount equal to its respective participation in same day funds, at the office of
the Issuing Bank specified in such notice, not later than 1:00 p.m. (New York
City time) on the first Business Day (under the laws of the jurisdiction of the
Issuing Bank) after the date notified by the Agent. In the event that any Lender
fails to make available to the Issuing Bank the amount of such Lender's
participation in such Letter of Credit as provided in this Section 3.6, the
Issuing Bank shall be entitled to recover such amount on demand from such Lender
together with interest at the Federal Funds Rate. The Agent or the Issuing Bank
shall distribute to each other Lender which has paid all amounts payable by it
under this Section 3.6 with respect to any Letter of Credit issued by the
Issuing Bank such other Lender's Proportionate Share of all payments
subsequently received by the Agent or the Issuing Bank from the Borrowers in
reimbursement of drawings honored by the Issuing Bank under such Letter of
Credit when such payments are received.

                  SECTION 3.7. NATURE OF ISSUING BANK'S DUTIES. In determining
whether to pay under any Letter of Credit, the Issuing Bank shall be responsible
only to determine that the documents and certificates required to be delivered
under that Letter of Credit have been delivered and that they comply on their
face with the requirements of that Letter of Credit. Subject to the last
sentence of this Section 3.7, as between the Borrowers, the Issuing Bank and
each other Lender, the Borrowers assume all risks of the acts and omissions of
the Issuing Bank, or misuse of the Letters of Credit issued by the Issuing Bank
by the respective beneficiaries of such Letters of Credit. In furtherance and
not in limitation of the foregoing, neither the Issuing Bank nor any of the
Lenders shall be responsible (i) for the form, validity, sufficiency, accuracy,
genuineness or legal effects of any document submitted by any party in
connection with the application for and issuance of or any drawing honored under
such Letters of Credit even if it should in fact prove to be in any or all
respects invalid, insufficient, inaccurate, fraudulent or forged, (ii) for the
validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign any such Letter of Credit, or the rights or
benefits thereunder or proceeds thereof, in whole or in part, which may prove to
be invalid or ineffective for any reason, (iii) for failure of the beneficiary
of any such Letter of Credit to comply fully with conditions required in order
to draw upon such Letter of Credit, (iv) for errors, omissions, interruptions or
delays in transmission or delivery of any messages, by mail, cable, telegraph,
telex, telecopy or otherwise, whether or not they be

                                      -45-


<PAGE>   52




in cipher, (v) for errors in interpretation of technical terms, (vi) for any
loss or delay in the transmission or otherwise of any document required in order
to make a drawing under any such Letter of Credit, or of the proceeds thereof,
(vii) for the misapplication by the beneficiary of any such Letter of Credit, of
the proceeds of any drawing honored under such Letter of Credit, and (viii) for
any consequences arising from causes beyond the control of the Issuing Bank or
the other Lenders. None of the above shall affect, impair, or prevent the
vesting of any of the Issuing Bank's rights or powers hereunder. Any action
taken or omitted to be taken by the Issuing Bank under or in connection with any
Letter of Credit, if taken or omitted in the absence of gross negligence or
willful misconduct, shall not create any liability of the Issuing Bank to the
Borrowers or any Lender.

                  SECTION 3.8. OBLIGATIONS ABSOLUTE. The obligations of the
Borrowers to reimburse, jointly and severally, the Issuing Bank for drawings
honored under the Letters of Credit and the obligations of the Lenders under
Section 3.6 shall be unconditional and irrevocable and shall be paid strictly in
accordance with the terms of this Credit Agreement under all circumstances
including, without limitation, the following circumstances: (i) any lack of
validity or enforceability of this Credit Agreement, any Letter of Credit, any
Letter of Credit Agreement or any other agreement or instrument relating thereto
(the "LETTER OF CREDIT RELATED DOCUMENTS"); (ii) the existence of any claim,
setoff, defense or other right which the Borrowers or any Affiliate of the
Borrowers may have at any time against a beneficiary or any transferee of any
Letter of Credit (or any Persons or entities for whom any such beneficiary or
transferee may be acting), the Issuing Bank, any Lender or any other Person,
whether in connection with this Credit Agreement, the other Credit Documents,
the transactions contemplated herein or therein or any unrelated transaction;
(iii) any draft, demand, certificate or any other documents presented under any
Letter of Credit proving to be forged, fraudulent, invalid or insufficient in
any respect or any statement therein being untrue or inaccurate in any respect;
(iv) the surrender or impairment of any security for the performance or
observance of any of the terms of any of the Credit Documents; (v) payment by
the Issuing Bank under any Letter of Credit against presentation of a demand,
draft or certificate or other document which does not comply with the terms of
such Letter of Credit; (vi) failure of any drawing under a Letter of Credit or
any non-application or misapplication by the beneficiary of the proceeds of any
drawing; or (vii) the fact that a Default or Event of Default shall have
occurred and be continuing; PROVIDED, HOWEVER, that the Borrowers shall have no
obligation to reimburse the Issuing Bank and the Lenders shall have no
obligation under Section 3.6 in the event of the Issuing Bank's willful
misconduct or gross negligence in determining

                                      -46-

whether documents presented under the Letter of Credit comply with the terms of
such Letter of Credit.

                  SECTION 4.1. INTEREST ON PRIME RATE LOANS. The Borrowers,
jointly and severally, shall pay to the Agent for the benefit of the Lenders
interest on Prime Rate Loans two Business Days after the last Business Day of
each month, calculated monthly in arrears at an interest rate per annum equal to
the Prime Lending Rate plus the Applicable Margin with respect to Prime Rate
Loans on the average net balances owing to the Agent and the Lenders at the
close of business each day during such month. The rate under this Section 4.1
shall change each day as the Prime Lending Rate changes.

                  SECTION 4.2. INTEREST ON EURODOLLAR RATE LOANS. The Borrowers,
jointly and severally, shall pay to the Agent for the benefit of the Lenders
interest on Eurodollar Rate Loans on the last day of each Interest Period with
respect to such Eurodollar Rate Loan and, in the case of an Interest Period
longer than three months, on the date occurring every three months from the
first day of such Interest Period, at the date of conversion of such Eurodollar
Rate Loan (or a portion thereof) to a Prime Rate Loan, and at maturity of such
Eurodollar Rate Loan, in each case at a per annum interest rate equal during the
Interest Period for such Eurodollar Loan to the Adjusted Eurodollar Rate for the
Interest Period in effect for such Eurodollar Rate Loan plus the Applicable
Margin with respect to Eurodollar Rate Loans. After maturity of such Eurodollar
Rate Loan (whether by acceleration or otherwise), interest shall be payable upon
demand. The Agent, upon determining the Adjusted Eurodollar Rate for any
Interest Period, shall promptly notify the Borrowers and the Lenders by
telephone (confirmed promptly in writing) or in writing thereof. Each
determination by the Agent of an interest rate hereunder shall be conclusive and
binding for all purposes, absent manifest error.

                  SECTION 4.3. INTEREST AND LETTER OF CREDIT FEES AFTER EVENT OF
DEFAULT. From the date of occurrence of any of the Events of Default specified
in Section 8.1(a), (f) or (g), until the earlier of the date upon which (i) all
Obligations shall have been paid and satisfied in full or (ii) such Event of
Default shall have been waived or cured, interest on the Loans, and Letter of
Credit Fees on Letter of Credit Obligations, shall each be payable on demand at
a rate per annum equal to, with respect to the Loans, the rate in effect under
Section 4.1, plus two percent (2%), and with respect to the Letter of Credit

                                      -47-


<PAGE>   54




Obligations, the rate in effect under the first sentence of Section 4.4(a), plus
two percent (2%). From the date of occurrence of any of the Events of Default
specified in Section 8.1(b), (c), (d), (e), (h), (i), (j), (k) or (l), until the
earlier to occur of the events described in clauses (i) and (ii) of the
preceding sentence, interest on the Loans and Letter of Credit Fees on Letter of
Credit Obligations shall be payable on demand of the Majority Lenders, at the
rates respectively set forth in the preceding sentence.

                  SECTION 4.4. LETTER OF CREDIT FEES.

                    (a) The Borrowers, jointly and severally, shall pay to the
Agent for distribution to the Lenders two Business Days after the last Business
Day of each month a fee (the "LETTER OF CREDIT FEE"), in an amount equal to a
rate per annum equal to the Applicable Margin with respect to the Letter of
Credit Fee of the daily average amount of Letter of Credit Obligations
outstanding during the immediately preceding month. In addition, the Borrowers,
jointly and severally, shall pay to the Agent, for its own benefit, the letter
of credit facing fees outlined in the Fee Letter.

                    (b) The Borrowers, jointly and severally, shall also pay the
customary charges, fees and expenses of the Issuing Bank for the issuance,
administration and negotiation of each Letter of Credit (the "ISSUING BANK
FEES"). Each determination by the Agent of Letter of Credit Fees and other fees,
charges and expenses under this Section shall be conclusive and binding for all
purposes, absent manifest error.

                  SECTION 4.5. UNUSED LINE FEE. The Borrowers, jointly and
severally, shall pay to the Agent for distribution to the Lenders two Business
Days after the last Business Day of each month and on the Expiration Date a fee
equal to a rate per annum equal to the Applicable Margin with respect to the
Unused Line Fee calculated monthly in arrears on the average unused portion of
the total Commitments at the close of business each day during such month or
occurring prior to the Expiration Date (the "UNUSED LINE FEE").

                  SECTION 4.6. OTHER FEES AND EXPENSES. The Borrowers, jointly
and severally, agree to pay fees to BT Commercial Corporation in the amounts and
at the times set forth in the Fee Letter and shall be obligated to reimburse the
Agent's and the Collateral Agent's Expenses promptly upon demand.

                  SECTION 4.7. CALCULATIONS. All calculations of (i) interest
hereunder and (ii) Fees, including, without limitation, Unused Line Fees and
Letter of Credit Fees, shall be made by the Agent, on the basis of a year of 360
days for the actual number of days elapsed (including the first day but

                                      -48-


<PAGE>   55




excluding the last day) occurring in the period for which such interest or Fees
are payable. Each determination by the Agent of an interest rate, Fee or other
payment hereunder shall be conclusive and binding for all purposes, absent
manifest error.

                  SECTION 4.8. SPECIAL PROVISIONS RELATING TO EURODOLLAR RATE 
LOANS.

                    (a) CONTINUATION. With respect to any Borrowing consisting
of Eurodollar Rate Loans, Wang may (so long as no Default or Event of Default
has occurred and is continuing), subject to the provisions of Section 4.8(c),
elect to maintain such Borrowing or any portion thereof as consisting of
Eurodollar Rate Loans by selecting a new Interest Period for such Borrowing,
which new Interest Period shall commence on the last day of the immediately
preceding Interest Period. Each selection of a new Interest Period shall be made
by notice given not later than 2:00 p.m. (New York City time) on the third
Business Day prior to the date of any such continuation relating to Eurodollar
Rate Loans, by Wang to the Agent. Such notice by Wang of a continuation (a
"NOTICE OF CONTINUATION") shall be by telephone or facsimile transmission, and
if by telephone, promptly confirmed in writing substantially in the form of
Exhibit D, in each case specifying (i) the date of such continuation, (ii) the
Type of Loans subject to such continuation, (iii) the aggregate amount of Loans
subject to such continuation and (iv) the duration of the selected Interest
Period. Wang may elect to maintain more than one Borrowing consisting of
Eurodollar Rate Loans by combining such Borrowings into one Borrowing and
selecting a new Interest Period pursuant to this Section 4.8(a). If Wang shall
fail to select a new Interest Period for any Borrowing consisting of Eurodollar
Rate Loans in accordance with this Section 4.8(a), such Revolving Loans will
automatically, on the last day of the then existing Interest Period therefore,
convert into Prime Rate Loans. The Agent shall give each Lender prompt notice by
telephone or facsimile transmission of each Notice of Continuation.

                  (b) CONVERSION. Wang may on any Business Day (so long as no
Default or Event of Default has occurred and is continuing), upon notice (each
such notice, a "NOTICE OF CONVERSION") given to the Agent, and subject to the
provisions of Section 4.8(c), convert the entire amount of or a portion of all
Loans of one Type comprising the same Borrowing into Loans of another Type;
PROVIDED, HOWEVER, that any conversion of any Eurodollar Rate Loans into Loans
of another Type shall be made on, and only on, the last day of an Interest
Period for such Eurodollar Rate Loans and, upon conversion of any Prime Rate
Loans into Loans of another Type, the Borrowers, jointly and severally, shall
pay accrued interest to the date of conversion on the principal amount
converted. Each such Notice of Conversion shall be given not later than 10:00
a.m. (New York

                                      -49-


<PAGE>   56




City time) on the Business Day prior to the date of any proposed conversion into
Prime Rate Loans and on the third Business Day prior to the date of any proposed
conversion into Eurodollar Rate Loans. Subject to the restrictions specified
above, each Notice of Conversion shall be by telephone or facsimile
transmission, and if by telephone, promptly confirmed in writing substantially
in the form of Exhibit E, in each case specifying (i) the requested date of such
conversion, (ii) the Type of Loans to be converted, (iii) the portion of such
Type of Loan to be converted, (iv) the Type of Loan such Loans are to be
converted into and (v) if such conversion is into Eurodollar Rate Loans, the
duration of the Interest Period of such Loan. Each conversion shall be in an
aggregate amount for the Loans of all Lenders of not less than $1,000,000 or an
integral multiple of $100,000 in excess thereof. Wang may elect to convert the
entire amount of or a portion of all Loans of one Type comprising more than one
Borrowing into Loans of another Type by combining such Borrowings into one
Borrowing; PROVIDED, HOWEVER, that if the Borrowings so combined consist of
Eurodollar Rate Loans, such Loans shall have Interest Periods ending on the same
date.

                    (c) CERTAIN LIMITATIONS ON EURODOLLAR RATE LOANS. The right
of Wang to maintain, select, continue or convert Eurodollar Rate Loans shall be
limited as follows:

                    (i) If the Agent is not offering U.S. dollar deposits (in
         the applicable amounts) in the London interbank market, or the Agent
         determines that adequate and fair means do not otherwise exist for
         ascertaining the Eurodollar Rate for Eurodollar Rate Loans comprising
         any requested Borrowing, continuation or conversion, the right of Wang
         to select or maintain Eurodollar Rate Loans for such Borrowing or any
         subsequent Borrowing shall be suspended until the Agent shall notify
         Wang and the Lenders that the circumstances causing such suspension no
         longer exists, and each Loan comprising such Borrowing shall be made as
         a Prime Rate Loan.

                   (ii) If the Majority Lenders shall, at least one Business Day
         before the date of any requested Borrowing, continuation or conversion,
         notify the Agent that the Eurodollar Rate for Loans comprising such
         Borrowing will not adequately reflect the cost to such Lenders of
         making or funding their respective Loans for such Borrowing, the right
         of Wang to select Eurodollar Rate Loans for such Borrowing shall be
         suspended until the Agent shall notify Wang and the Lenders that the
         circumstances causing such suspension no longer exist, and each Loan
         comprising such Borrowing shall be made as a Prime Rate Loan.

                  (iii) If at any time any Lender determines (which 
         determination shall, absent manifest error, be conclusive

                                      -50-


<PAGE>   57




         and binding on all parties) that the making, continuation or conversion
         of any Loan as a Eurodollar Rate Loan has become unlawful or
         impermissible by reason of compliance by that Lender with any law,
         governmental rule, regulation or order of any Governmental Authority
         (whether or not having the force of law or resulting in costs or
         penalties), then, and in any such event, such Lender may give notice of
         that determination in writing, to Wang and the Agent and the Agent
         shall promptly transmit the notice to each other Lender. Until such
         Lender gives notice otherwise, the right of Wang to select Eurodollar
         Rate Loans from that Lender shall be suspended and each Eurodollar Rate
         Loan outstanding from that Lender shall automatically and immediately
         convert to a Prime Rate Loan.

                   (iv) Until the first Business Day following the Syndication
         Date, the right of Wang to select Eurodollar Rate Loans for any
         Borrowing shall be limited to Eurodollar Rate Loans with an Interest
         Period of one month.

                    (v) There shall not be outstanding at any one time more than
         an aggregate of seven (7) Borrowings of Loans which consist of
         Eurodollar Rate Loans.

                   (vi) No Agent Advance shall be made as a Eurodollar Rate 
         Loan.

                    (d) COMPENSATION.

                    (i) Each Notice of Continuation and Notice of Conversion
         shall be irrevocable by and binding on Wang. In the case of any
         Borrowing, continuation or conversion that the related Notice of
         Borrowing, Notice of Continuation or Notice of Conversion specifies is
         to be comprised of Eurodollar Rate Loans, the Borrowers, jointly and
         severally, shall indemnify each Lender against any loss, cost or
         expense incurred by such Lender as a result of any failure to fulfill,
         on or before the date for such Borrowing, continuation or conversion
         specified in such Notice of Borrowing, Notice of Continuation or Notice
         of Conversion, the applicable conditions set forth in Article V,
         including, without limitation, any loss (excluding loss of anticipated
         profits), cost or expense incurred by reason of the liquidation or
         re-employment of deposits or other funds acquired by such Lender to
         fund the Loan to be made by such Lender as part of such Borrowing,
         continuation or conversion.

                   (ii) If any payment of principal of, or conversion or
         continuation of, any Eurodollar Rate Loan is made other than on the
         last day of the Interest Period for such Loan as a result of a payment,
         prepayment, conversion or continuation

                                      -51-

         of such Loan or acceleration of the maturity of the Revolving Notes
         pursuant to Article VIII or for any other reason, the Borrowers,
         jointly and severally, shall, upon demand by any Lender (with a copy of
         such demand to the Agent), pay to the Agent for the account of such
         Lender any amounts required to compensate such Lender for any
         additional losses, costs or expenses which it may reasonably incur as a
         result of such payment, including, without limitation, any loss
         (excluding loss of anticipated profits), cost or expense incurred by
         reason of the liquidation or reemployment of deposits or other funds
         acquired by any Lender to fund or maintain such Loan.

                  (iii) Calculation of all amounts payable to a Lender under
         this Section 4.8(d) shall be made as though such Lender elected to fund
         all Eurodollar Rate Loans by purchasing U.S. dollar deposits in its
         Eurodollar Lending Office's interbank eurodollar market.

                     SECTION 4.9. INDEMNIFICATION IN CERTAIN EVENTS. If after
the Closing Date, either (i) any change in or in the interpretation of any law
or regulation is introduced, including, without limitation, with respect to
reserve requirements, applicable to the Agent, to any of the Lenders, the
Collateral Agent or any other banking or financial institution from whom any of
the Lenders borrows funds or obtains credit (a "FUNDING BANK"), or (ii) the
Agent, the Collateral Agent, a Funding Bank or any of the Lenders complies with
any future guideline or request from any central bank or other Governmental
Authority, or (iii) the Agent, the Collateral Agent, a Funding Bank or any of
the Lenders determines that the adoption of any applicable law, rule or
regulation regarding capital adequacy, or any change therein, or any change in
the interpretation or administration thereof by any Governmental Authority,
central bank or comparable agency charged with the interpretation or
administration thereof has or would have the effect described below, or the
Agent, the Collateral Agent, a Funding Bank or any of the Lenders complies with
any request or directive regarding capital adequacy (whether or not having the
force of law) of any such authority, central bank or comparable agency, and in
the case of any event set forth in this clause (iii), such adoption, change or
compliance has or would have the direct or indirect effect of reducing the rate
of return on any of the Lenders' capital as a consequence of its obligations
hereunder to a level below that which such Lender could have achieved but for
such adoption, change or compliance (taking into consideration the Agent's, the
Collateral Agent's, or such Funding Bank's or Lender's policies as the case may
be with respect to capital adequacy) by an amount deemed by such Lender to be
material, and any of the foregoing events described in clauses (i), (ii) or
(iii) increases the cost to the Agent, the Collateral Agent, the Issuing Bank or
any of the Lenders of (A) funding or maintaining the total Commitments or (B)
issuing,

                                      -52-


<PAGE>   59



making or maintaining any Letter of Credit or of purchasing or maintaining any
participation therein, or reduces the amount receivable in respect thereof by
the Agent, the Collateral Agent, the Issuing Bank or any Lender, then the
Borrowers, jointly and severally, shall upon demand by the Agent, pay to the
Agent, for the account of each applicable Lender or, as applicable, the
Collateral Agent, the Issuing Bank or a Funding Bank, additional amounts
sufficient to indemnify the Lenders against such increase in cost or reduction
in amount receivable. A certificate as to the amount of such increased cost and
setting forth in reasonable detail the calculation thereof shall be submitted to
the Borrowers by the Agent, or the applicable Lender, the Collateral Agent,
Issuing Bank or Funding Bank, and shall be conclusive absent manifest error.
Prior to making any such demand, each of the Lenders, the Agent, the Collateral
Agent, Funding Bank or other such party shall use reasonable efforts to
designate a different Applicable Lending Office if such a designation could
reduce or eliminate any such payment.

                  SECTION 4.10.  NET PAYMENTS.

                  (a) Any and all payments by the Borrowers hereunder, under the
Revolving Loans or under the Letters of Credit to or for the benefit of any
Lender, the Issuing Bank, the Collateral Agent or the Agent shall be made free
and clear of and without deduction or withholding for any and all present or
future taxes, levies, imposts, deductions, charges or withholdings and
penalties, interests and all other liabilities with respect thereto ("TAXES"),
including any Taxes imposed under Section 7701(l) of the Internal Revenue Code,
excluding, (i) in the case of each such Lender, the Issuing Bank, the Collateral
Agent or the Agent, taxes imposed on its net income (including, without
limitation, any taxes imposed on branch profits) and franchise taxes imposed on
it by the jurisdiction under the laws of which such Lender, the Issuing Bank,
the Collateral Agent or the Agent (as the case may be) is organized or any
political subdivision thereof, (ii) in the case of each Lender, taxes imposed on
its net income (including, without limitation, any taxes imposed on branch
profits), and franchise taxes imposed on it, by the jurisdiction of such
Lender's Applicable Lending Office or any political subdivision thereof, (iii)
in the case of each such Lender, the Issuing Bank, the Collateral Agent and the
Agent, any Taxes that are in effect and that would apply to a payment to such
Lender, the Issuing Bank, the Collateral Agent or Agent, as applicable, as of
the Closing Date (other than any Taxes imposed under Section 7701(l) of the
Internal Revenue Code), and (iv) if any Person acquires any interest in this
Credit Agreement, any Revolving Loan or Letter of Credit pursuant to the
provisions hereof, or a Foreign Lender or the Agent changes the office in which
the Borrowing is made, accounted for or booked (any such person, or such Foreign
Lender or the Agent in that event, being referred to as a "TAX TRANSFEREE"), any
Taxes (other than Taxes

                                      -53-


<PAGE>   60



imposed under Section 7701(l) of the Internal Revenue Code) to the extent that
they are in effect and would apply to a payment to such Tax Transferee as of the
date of the acquisition of such interest or change in office, as the case may be
(all such nonexcluded Taxes being hereinafter referred to as "COVERED TAXES").
If the Borrowers shall be required by law to deduct or withhold any Covered
Taxes from or in respect of any sum payable hereunder, under any Revolving Loan
or under any Letter of Credit to or for the benefit of any Lender, the Issuing
Bank, the Collateral Agent or the Agent or any Tax Transferee, (A) the sum
payable shall be increased as may be necessary so that after making all required
deductions or withholdings of Covered Taxes (including deductions of Covered
Taxes applicable to additional sums payable under this Section 4.10) such
Lender, the Issuing Bank, the Agent, the Collateral Agent or such Tax
Transferee, as the case may be, receives an amount equal to the sum it would
have received had no such deductions or withholdings been made, (B) such
Borrower shall make such deductions or withholdings and (C) such Borrower shall
pay the full amount so deducted or withheld to the relevant taxation authority
or other authority in accordance with applicable law.

                    (b) In addition, the Borrowers, jointly and severally, agree
to pay any present or future stamp, documentary, excise, privilege, intangible
or similar levies that arise at any time or from time to time (i) from any
payment made under any and all Credit Documents, (ii) from the transfer of the
rights of the Lender under any Credit Documents to any transferee, or (iii) from
the execution or delivery by the Borrowers of, or from the filing or recording
or maintenance of, or otherwise with respect to the exercise by the Agent or the
Lenders of their rights under, any and all Credit Documents (hereinafter
referred to as "OTHER TAXES").

                    (c) The Borrowers, jointly and severally, indemnify each
Lender, the Issuing Bank, the Agent, the Collateral Agent and any Tax Transferee
for the full amount of (i) Covered Taxes imposed on or with respect to amounts
payable hereunder, (ii) Other Taxes, and (iii) any Taxes (other than Covered
Taxes imposed by any jurisdiction on amounts payable under this Section 4.10)
paid by such Lender, the Issuing Bank, the Collateral Agent or the Agent or such
Tax Transferee, as the case may be, and any liability (including penalties,
interest and expenses) arising solely therefrom or with respect thereto. Payment
of this indemnification shall be made within 30 days from the date such Lender,
the Issuing Bank or the Agent or Tax Transferee certifies and sets forth in
reasonable detail the calculation thereof as to the amount and type of such
Taxes. Any such certificate submitted by the Lender, the Issuing Bank, the
Collateral Agent or Agent or Tax Transferee in good faith to the Borrowers
shall, absent manifest error, be final, conclusive and binding on all parties.

                                      -54-


<PAGE>   61




                    (d) Within 30 days after having received a receipt of
Covered Taxes or Other Taxes, the Borrowers will furnish to the Agent the
original or a certified copy of a receipt evidencing payment thereof.

                    (e) On or before the Closing Date, each Foreign Lender shall
deliver to the Agent and the Borrowers (i) two valid, duly completed copies of
IRS Form 1001 or 4224 or successor applicable form, as the case may be, and any
other required form, certifying in each case that such Foreign Lender is
entitled to receive payments under this Credit Agreement or the Revolving Loans
payable to it without deduction or withholding of any United States federal
income taxes or with such withholding imposed at a reduced rate (the "REDUCED
RATE"), and (ii) a valid, duly completed IRS Form W-8 or W-9 or successor
applicable form, as the case may be, to establish an exemption from United
States backup withholding tax. Each such Foreign Lender shall also deliver to
the Agent and the Borrowers two further copies of said Form 1001 or 4224 and W-8
or W-9, or successor applicable forms, or other manner of required
certification, as the case may be, on or before the date that any such form
expires or becomes obsolete or otherwise is required to be resubmitted as a
condition to obtaining an exemption from a required withholding of United States
federal income tax or entitlement to having such withholding imposed at the
Reduced Rate or after the occurrence of any event requiring a change in the most
recent form previously delivered by it to the Borrowers and the Agent, and such
extensions or renewals thereof as may reasonably be requested by the Borrowers
and the Agent, certifying (i) in the case of a Form 1001 or 4224 that such
Foreign Lender is entitled to receive payments under this Credit Agreement or
the Revolving Notes payable to it without deduction or withholding of any United
States federal income taxes, unless in any such case any change in a tax treaty
to which the United States is a party, or any change in law or regulation of the
United States or official interpretation thereof has occurred after the Closing
Date and prior to the date on which any such delivery would otherwise be
required that renders all such forms inapplicable or that would prevent such
Foreign Lender from duly completing and delivering any such form with respect to
it, and such Foreign Lender advises the Borrowers and the Agent that it is not
capable of receiving payments without any deduction or withholding at the
Reduced Rate, or (ii) in the case of a Form W-8 or W-9, establishing an
exemption from United States backup withholding tax.

                    (f) If a Tax Transferee that is organized under the laws of
a jurisdiction outside of the United States acquires an interest in this Credit
Agreement or any Revolving Loan or a Foreign Lender changes the office through
which Loans are made, accounted for or booked, the transferor, or the applicable
Foreign Lender, in the case of a change of office, shall cause such Tax
Transferee to agree that, on or prior to the effective

                                      -55-


<PAGE>   62




date of such acquisition or change, as the case may be, it will deliver to the
Borrowers and the Agent (i) two valid, duly completed copies of IRS Form 1001 or
4224 or successor applicable form, as the case may be, and any other required
form, certifying in each case that such Tax Transferee is entitled to receive
payments under this Credit Agreement and the Revolving Notes payable to it
without deduction or withholding of United States federal income tax or with
such withholding imposed at a Reduced Rate; and (ii) a valid, duly completed IRS
Form W-8 or W-9 or successor applicable form, as the case may be, to establish
an exemption from United States backup withholding tax. Each Tax Transferee that
delivers to the Borrowers and the Agent a Form 1001 or 4224, and Form W-8 or W-9
and any other required form, pursuant to the next preceding sentence, further
undertakes to deliver two further copies of the said Form 1001 or 4224 and Form
W-8 or W-9, or successor applicable forms, or other manner of required
certification, as the case may be, on or before the date that any such form
expires or becomes obsolete or otherwise is required to be resubmitted as a
condition to obtaining an exemption from a required withholding of United States
federal income tax or entitlement to having such withholding imposed at the
Reduced Rate or after the occurrence of any event requiring a change in the most
recent form previously delivered by it to the Borrowers and the Agent, and such
extensions or renewals thereof as may reasonably be requested by the Borrowers
and the Agent, certifying (i) in the case of a Form 1001 or 4224 that such Tax
Transferee is entitled to receive payments under this Credit Agreement without
deduction or withholding of any United States federal income taxes or with such
withholding imposed at the Reduced Rate, unless any change in treaty, law or
regulation or official interpretation thereof has occurred after the effective
date of such acquisition or change and prior to the date on which any such
delivery would otherwise be required that renders all such forms inapplicable or
that would prevent such Tax Transferee from duly completing and delivering any
such form with respect to it, and such Tax Transferee advises the Borrowers and
the Agent that it is not capable of receiving payments (a) without any deduction
or withholding of United States federal income tax or (b) with such withholding
at the Reduced Rate, as the case may be, or (ii) in the case of a Form W-8 or
W-9, establishing an exemption from United States backup withholding tax.

                    (g) If any Taxes for which the Borrowers would be required
to make payment under this Section 4.10 are imposed, the Lender, the Issuing
Bank, the Collateral Agent or the Agent, as the case may be, shall use its
reasonable best efforts to avoid or reduce such Taxes by taking any appropriate
action (including, without limitation, assigning its rights hereunder to a
related entity or a different office) which would not in the sole opinion of
such Lender, the Issuing Bank, the Collateral Agent or the Agent be otherwise
disadvantageous to such Lender, the Issuing Bank or the Agent, as the case may
be.

                    (h) Without prejudice to the survival of any other agreement
of the Borrowers hereunder, the agreements and obligations of the Borrowers
contained in this Section 4.10 shall survive the payment in full of the
Obligations.

                    SECTION 4.11. AFFECTED LENDERS. If the Borrowers are
obligated to pay to any Lender any amount under Sections 4.9 or 4.10 materially
in excess of any such amounts payable to the other Lenders or if any Lender is a
Defaulting Lender and remains as such for five Business Days following its
receipt of written notice from the Agent or the Borrowers, or if the Borrowers
are exercising their right to replace a non-consenting Lender under Section
10.11(d), the Borrowers may, if no Default or Event of Default then exists,
replace such Lender with another lender reasonably acceptable to the Agent, and
such Lender hereby agrees to be so replaced subject to the following:

                    (a) The obligations of the Borrowers hereunder to the Lender
to be replaced (including such increased or additional costs incurred from the
date of notice to the Borrowers of such increase or additional costs through the
date such Lender is replaced hereunder) shall be paid in full to the Agent for
the account of such Lender concurrently with such replacement;

                    (b) The replacement Lender shall be a bank or other
financial institution that is not subject to the increased costs arising under
Section 4.9 which may have effectuated the Borrowers' election to replace any
Lender hereunder, and each such replacement Lender shall execute and deliver to
the Agent such documentation satisfactory to the Agent pursuant to which such
replacement Lender is to become a party hereto, conforming to the provisions of
Section 10.8, with a Commitment equal to that of the Lender being replaced
(before giving effect to Section 2.8) and shall make a Loan or Loans in the
aggregate principal amount equal to the aggregate outstanding principal amount
of the Loan or Loans of the Lender being replaced (or Loans that should have
been made but for a Defaulting Lender's failure to lend);

                    (c) Upon such execution of such documents referred to in
clause (b) and repayment of the amounts referred to in clause (a), the
replacement lender shall be a "Lender" with a Commitment as specified
hereinabove and the Lender being replaced shall cease to be a "Lender"
hereunder, except with respect to indemnification provisions under this Credit
Agreement, which shall survive as to such replaced Lender;

                    (d) The Agent shall reasonably cooperate in effectuating the
replacement of any Lender under this Section 4.11, but at no time shall the
Agent be obligated to initiate any such replacement; and

                    (e) Any Lender replaced under this Section 4.11 shall be
replaced at the Borrowers' sole cost and expense and at no cost or expense to
the Agent or any of the Lenders (other than a Defaulting Lender).

failure to qualify or be in good standing is not reasonably likely to result in
a Material Adverse Effect. Schedule 6.1(a) lists all jurisdictions in which Wang
and each Domestic Subsidiary, FSI and its Subsidiaries are qualified to do
business as foreign corporations as of the Closing Date.

                    (b) AUTHORITY. Each Borrower and each other Credit Party has
the requisite corporate power and authority to execute, deliver and perform each
of the Credit Documents and INET Purchase Documents to which it is a party. All
corporate action necessary for the execution, delivery and performance of any of
the Credit Documents has been or, prior to the execution and delivery thereof,
will be taken. All corporate action necessary for the execution, delivery and
performance of any of the INET Purchase Documents to which a Credit Party is a
party has been taken.

                    (c) ENFORCEABILITY. This Credit Agreement is and, when
executed and delivered, each other Credit Document and INET Purchase Document is
and, when executed, and delivered, will be the legal, valid and binding
obligation of the Borrowers or of any Credit Party which is a party thereto,

limited by (i) bankruptcy, insolvency or similar laws affecting creditors'
rights generally, and (ii) general principles of equity.

                    (d) NO CONFLICT. The execution, delivery and performance of
each Credit Document by the Borrowers or any other Credit Party does not, and
the execution, delivery and performance by Wang of each INET Purchase Document
to which it is a party will not, contravene (i) the Governing Documents of the
Borrowers or any other Credit Party, or (ii) any Requirement of Law (including,
without limitation, HSR and the other Acquisition Notification Laws) or (iii)
any franchise, license, permit, indenture, contract, lease, agreement,
instrument or other commitment to which it is a party or by which it or any of
its properties are bound, in each case, other than those which are not
reasonably likely to result in a Material Adverse Effect, and will not, except
as contemplated herein, result in the imposition of any Liens upon any of its
properties.

<PAGE>   69




                    (e) CONSENTS AND FILINGS. No material consent,
authorization, approval or filing is required in connection with the execution,
delivery and performance of this Credit Agreement, any Credit Document or any
INET Purchase Document, or the continuing operations of Wang and any Subsidiary,
except: (i) those that have been obtained or made; (ii) filings necessary to
create, perfect or retain the perfection of Liens against the Collateral; (iii)
filings required under HSR or the other Acquisition Notification Laws; and (iv)
in the case of the continuing operations of Wang and each Subsidiary, those the
failure to obtain are not reasonably likely to have a Material Adverse Effect.
All applicable waiting periods under HSR and the other Acquisition Notification
Laws will have expired or been earlier terminated prior to the Closing Date.

                    (f) GOVERNMENT REGULATION. Neither of the Borrowers nor any
other Credit Party is subject to regulation under the Public Utility Holding
Company Act of 1935, the Federal Power Act, the Investment Company Act of 1940,
or any other Requirement of Law that limits its ability to incur indebtedness or
its ability to consummate the transactions contemplated in this Credit Agreement
and the other Credit Documents.

                    (g) SOLVENCY. The fair saleable value of the assets of Wang
and its Subsidiaries on a consolidated basis, WFI and its Subsidiaries on a
consolidated basis, Dataserv and its Subsidiaries on a consolidated basis, Wang
Canada and its Subsidiaries on a consolidated basis and INET and its
Subsidiaries on a consolidated basis exceeds all their respective probable
liabilities, including those to be incurred pursuant to this Credit Agreement,
the other Credit Documents and the INET Purchase Documents. No Borrower and its
Subsidiaries on a consolidated basis (i) has unreasonably small capital in
relation to the business in which it is or proposes to be engaged and (ii) has
incurred, or believes that it will incur, after giving effect to the
transactions contemplated by this Credit Agreement, the other Credit Documents
and the INET Purchase Agreement, debts beyond its ability to pay as such debts
become due.

                    (h) RIGHTS IN COLLATERAL; PRIORITY OF LIENS. All property
consisting of Collateral is owned or leased by the Borrowers or another Credit
Party, free and clear of any and all Liens in favor of third parties, other than
Liens permitted under Section 7.2(a), and to the extent such Collateral consists
of real estate, the Borrowers or another Credit Party has good and marketable
title in fee simple to such real estate. Upon the proper filing of the UCC
financing statements, the security interests granted pursuant to the Credit
Documents constitute valid and enforceable first, prior and perfected Liens on
the Collateral to the extent such Liens can be perfected by the filing of such
financing statements.

                  (i)      FINANCIAL DATA.

                           (A) Wang has provided to the Agent and each of the
                  Lenders complete and accurate copies of annual audited
                  Financial Statements for the fiscal year ended June 30, 1995,
                  reported on by Ernst & Young LLP and unaudited Financial
                  Statements for the fiscal period ended March 31, 1996. Such
                  Financial Statements have been prepared in accordance with
                  GAAP consistently applied throughout the periods involved and
                  fairly present the respective financial positions, results of
                  operations and cash flows of Wang and its consolidated
                  Subsidiaries for each of the periods covered. Neither Wang nor
                  any of its consolidated Subsidiaries has any Contingent
                  Obligation, or liability for taxes or long-term leases, which
                  is not reflected in such Financial Statements or the footnotes
                  thereto. During the period from March 31, 1996 to and
                  including the Closing Date there has been no sale, transfer or
                  other disposition by Wang or any of its consolidated
                  Subsidiaries of any material part of its business or property
                  and no purchase or other acquisition of any business or
                  property (including any capital stock of any other Person
                  other than as part of the Acquired INET Stock) material in
                  relation to the consolidated financial condition of Wang and
                  its consolidated Subsidiaries at March 31, 1996, except for
                  the acquisitions of Dataserv and WSSM. Since March 31, 1996,
                  except as permitted under this Credit Agreement (a) there has
                  been no change, occurrence, development or event which has had
                  or is reasonably likely to have a Material Adverse Effect and
                  (b) no dividends or other returns of capital or other
                  distributions have been declared, paid or made upon the
                  capital stock of any Credit Party, except for dividends paid
                  to Wang by its Subsidiaries, regularly scheduled dividends to
                  holders of the Preferred Stock, dividends paid-in-kind and
                  payments in respect of the InterCompany Convertible
                  Instruments, nor has any of the capital stock of Wang been
                  redeemed, retired, purchased or otherwise acquired for value
                  by Wang or any of its Subsidiaries.

                           (B) INET has provided to the Agent and each of the
                  Lenders complete and accurate copies of annual audited balance
                  sheet, statement of operations, statement of cash flows and
                  statement of changes in shareholder's equity of INET and its
                  consolidated Subsidiaries (the "INET FINANCIAL STATEMENTS")
                  for the fiscal year ended December 31, 1995, reported on by
                  KPMG Peat Marwick and unaudited INET Financial Statements for
                  the fiscal period ended May 31, 1996. Such Financial
                  Statements have been prepared in

                                      -64-


<PAGE>   71




                  accordance with GAAP consistently applied throughout the
                  periods involved and fairly present the financial position,
                  results of operation and cash flows of INET for each of the
                  periods covered and, with respect to the unaudited Financial
                  Statements only, subject to normal year-end audit adjustments.
                  INET does not have any Contingent Obligation, or liability for
                  taxes or long-term leases, which is not reflected in such
                  Financial Statements or the footnotes thereto. During the
                  period from May 31, 1996 to and including the date hereof
                  there has been no sale, transfer or other disposition by INET
                  of any material part of its business or property and no
                  purchase or other acquisition of any business or property
                  (including any capital stock of any other Person) material in
                  relation to the financial condition of INET at June 30, 1996.

                  (j) CASH FLOW STATEMENTS. The forecasted cash flow statements 
and other financial statements of Wang and its consolidated Subsidiaries on a
consolidated basis dated July 24, 1996 for the fiscal years ended June 30, 1996,
1997, 1998 and 1999 delivered to the Agent and the Lenders in writing were
prepared in good faith on the basis of assumptions which were fair in light of
the conditions existing at the time of delivery of such forecasts, and
represented, at the time of delivery, such Borrower's best estimate of its and
(in the case of Wang) its consolidated Subsidiaries' future financial
performance. The forecasted statements described in this Section 6.1(j) should
not be construed by the Agent or the Lenders as a guaranty of results or
performance in the future.

                  (k) LOCATIONS OF OFFICES, RECORDS AND INVENTORY. As of the
Closing Date, the address of the principal place of business and chief executive
office of each Credit Party is set forth on Schedule 6.1(k). As of the Closing
Date, the books and records of each Credit Party, and all of its chattel paper
and records of Accounts, are maintained exclusively at the locations for such
Credit Party set forth on such Schedule. As of the Closing Date, there is no
jurisdiction in the United States or Canada in which any Credit Party has any
Collateral (except for vehicles and Inventory in transit for processing or at
customer sites) other than those jurisdictions with respect to such Credit Party
identified on Schedule 6.1(k). A complete list of the legal name and address of
each location in the United States or Canada at which any Credit Party's
Inventory or Equipment with an aggregate book value in excess of $500,000 is
located as of the Closing Date is set forth on Schedule 6.1(k). Schedule 6.1(k)

there are no proxies, irrevocable or otherwise, with respect to such shares, and
no equity securities of any of the Subsidiaries are or may become required to be

                    (m) NO JUDGMENTS OR LITIGATION. Except as set forth on

Wang or any of its consolidated Subsidiaries nor is there now pending or, to the
best of Wang's knowledge after diligent inquiry, threatened in writing any
litigation, contested claim, investigation, arbitration, or governmental
proceeding by or against Wang or any of its consolidated Subsidiaries that (i)
individually or in the aggregate, is reasonably likely to have a Material

contemplated hereby or thereby.

                    (n) LICENSES AND PERMITS. Except with respect to

                    (o) NO DEFAULTS. After giving effect to the closing of the
INET Purchase Agreement and the other transactions contemplated herein, neither
Wang nor any of its Subsidiaries is in default under any term of any indenture,
contract, lease, agreement, instrument or other commitment to which any of them
is a party or by which any of them is bound which, individually or in the
aggregate, is reasonably likely to have a Material Adverse Effect. The Borrowers
know of no dispute regarding any such indenture, contract, lease, agreement,
instrument or other commitment which, individually or in the aggregate, is
reasonably likely to have a Material Adverse Effect.

                    (p) LABOR MATTERS. Schedule 6.1(p) accurately sets forth all
collective bargaining agreements or other agreements with labor organizations to
which the Credit Parties or any of the Material Foreign Subsidiaries is a party
as of the Closing Date, and their dates of expiration. There are no existing or,
to the best of the Borrowers' knowledge after diligent inquiry, threatened
strikes, lockouts or other disputes relating to any collective bargaining or
other agreements with labor organizations to which Wang or any of its
Subsidiaries is a party which, individually or in the aggregate, is reasonably
likely to have a Material Adverse Effect.

                    (q) COMPLIANCE WITH LAW. Neither Wang nor any of its
Subsidiaries has violated or failed to comply with any Requirement of Law,
including without limitation ERISA, HSR, the other Acquisition Notification Laws
and Environmental Laws which violation or failure to comply, individually or in
the aggregate, is reasonably likely to have a Material Adverse Effect. The
transactions contemplated by the INET Purchase Agreement have been consummated
in accordance with all applicable laws except where the failure to do so is not
reasonably likely to have a Material Adverse Effect.

                    (r) ERISA; PENSION PLANS.

                    (i) As of the Closing Date, none of Wang, any of its
         Subsidiaries or any ERISA Affiliate maintains or contributes to any
         Plan, other than those listed on Schedule 6.1(r).

                   (ii) Wang, each of its Subsidiaries and each ERISA Affiliate
         have fulfilled all contribution obligations for each Plan (including
         obligations related to the minimum funding standards of ERISA and the
         Internal Revenue Code).

                  (iii) No Termination Event has occurred nor has any other
         event occurred that is likely to result in a Termination Event other
         than any Termination Event described in clause (ii) or (vi) of the
         definition of Termination Event that is not reasonably likely to have a
         Material Adverse Effect.

                   (iv) None of Wang or its Subsidiaries or any ERISA Affiliate
         is required to or reasonably expects to be required to provide security
         to any Plan under Section 401(a)(29) of the Internal Revenue Code.

                    (v) Wang, each of its Subsidiaries and each ERISA Affiliate
         are in material compliance in all respects with any applicable
         provisions of ERISA with respect to all Plans. Since June 30, 1995,
         there has been no prohibited transaction as defined in Section 406 of
         ERISA or Section 4975 of the Internal Revenue Code (a "PROHIBITED
         TRANSACTION") with respect to any Plan or, to the best knowledge of the
         Borrowers, with respect to any Multiemployer Plan, which, in either
         such case, is reasonably likely to result in any material liability to
         Wang, its Subsidiaries or any other ERISA Affiliates. Wang, its
         Subsidiaries and each ERISA Affiliate have made when due any and all
         payments required to be made under any agreement relating to a
         Multiemployer Plan or any Requirement of Law pertaining thereto. With
         respect to each Plan and Multiemployer Plan, Wang, its Subsidiaries and
         each ERISA Affiliate have not incurred any liability to the PBGC (other
         than required premium payments) and, except as set forth on Schedule
         6.1(r), have not had asserted against them any penalty for failure to
         fulfill the minimum funding requirements of ERISA.

                   (vi) To the Borrowers' best knowledge, each Multiemployer
         Plan is able to pay benefits when due.

                  (vii) As of the Closing Date, neither Wang, its Subsidiaries
         nor any ERISA Affiliate has instituted or, except as set forth on
         Schedule 6.1(r), intends to institute proceedings to terminate any
         Benefit Plan.

                  (viii) As of the Closing Date, except as set forth on Schedule
         6.1(r), the aggregate actuarial present value of all benefit
         liabilities (whether or not vested) under each Plan which is subject to
         Title IV of ERISA, determined on either an accumulated or projected
         benefit obligation basis, as disclosed in, and as of the date of, the
         most recent actuarial report for such Plan, does not exceed the
         aggregate fair market value of the assets of such Plan.

                   (ix) Neither Wang, its Subsidiaries nor any ERISA Affiliate
         has incurred or reasonably expects to incur any material withdrawal
         liability under ERISA to any Multiemployer Plan.

                    (x) To the extent that any Plan is insured, Wang, its
         Subsidiaries and all ERISA Affiliates have paid when due all

                                      -68-


<PAGE>   75




         premiums required to be paid for all periods through and
         including the Closing Date.

                   (xi) All pension plans maintained by Wang Canada are fully
         funded on an on-going and termination basis.

                    (s) BUSINESS AND PROPERTIES. Neither the business nor the
properties of Wang or any Subsidiary is affected by any fire, explosion,
accident, strike, lockout or other labor dispute, drought, storm, hail,
earthquake, embargo, act of God or of the public enemy or other casualty
(whether or not covered by insurance) which is reasonably likely to have a
Material Adverse Effect.

                    (t) COMPLIANCE WITH ENVIRONMENTAL LAWS. Except as set forth
on Schedule 6.1(t), (i) neither Wang nor any of its Subsidiaries is the subject
of a judicial or administrative proceeding or investigation relating to the
violation of any Environmental Laws, or asserting potential liability arising
from the release or disposal by any Person of any Hazardous Materials which,
individually or in the aggregate, is reasonably likely to have a Material
Adverse Effect, (ii) neither Wang nor any of its Subsidiaries has filed or
received any notice under any Environmental Laws concerning the treatment,
storage, disposal, spill or release or threatened release of any Hazardous
Materials at, on, beneath or adjacent to property owned or leased by Wang or any
of its Subsidiaries, or the release or threatened release at any other location
of any Hazardous Material generated, used, stored, treated, transported or
released by or on behalf of Wang or any of its Subsidiaries which, individually
or in the aggregate, is reasonably likely to have a Material Adverse Effect; and
(iii) neither Wang nor any of its Subsidiaries has knowledge of any contingent
liability for any release of any Hazardous Materials, in each case which,
individually or in the aggregate, is reasonably likely to have a Material
Adverse Effect.

                    (u) REAL PROPERTY. As of the Closing Date, except as set
forth on Schedule 6.1(u), no Credit Party either owns or leases any real
property.

                    (v) MATERIAL CONTRACTS. As of the Closing Date, set forth on
Schedule 6.1(v) is a complete and accurate list of all Material Contracts to
which Wang or any of its Subsidiaries is a party, showing as of the date hereof
the parties, subject matter and term thereof. Each such contract has been duly
authorized, executed and delivered by Wang and each Subsidiary that is a party
thereto, and, to the Borrowers' best knowledge, each other party thereto. Except
as described on Schedule 6.1(v), none of the Material Contracts contains any
burdensome restrictions on Wang or any of its Subsidiaries or any of their
respective properties, and each Material Contract is in full force and

                                      -69-


<PAGE>   76




effect and is binding upon and enforceable against all parties thereto in
accordance with its terms, and there exists no default under such contract by
any party thereto which is reasonably likely to have a Material Adverse Effect.

                    (w) INTELLECTUAL PROPERTY. As of the Closing Date, set forth
on Schedule 6.1(w) hereto is a complete and accurate list of all patents,
registered trademarks, trade names, registered service marks and registered
copyrights, and all applications therefor and material licenses thereof, of each
Credit Party, showing with regard to the registrations and applications the
jurisdiction in which registered or applied for, the registration or application
number, the date of registration (if any) and any expiration or application
date. Each of Wang and its Subsidiaries owns or licenses all material patents,
trademarks, service-marks, logos, tradenames, trade secrets, know-how,
copyrights, or licenses and other rights with respect to any of foregoing, which
are necessary for the operation of its business as presently conducted or
presently proposed to be conducted and which, if not obtained or held, is
reasonably likely to have a Material Adverse Effect. Except as set forth on
Schedule 6.1(w) hereto, to the best of the Borrowers' knowledge, neither Wang
nor any of its Subsidiaries has infringed any patent, trademark, service-mark,
tradename, copyright, license or other right owned by any other Person by the
sale or employment of any product, process, method, substance, part or other
material presently contemplated to be sold or employed, where such sale or
employment is reasonably likely to have a Material Adverse Effect on such Credit
Party and no claim or litigation is pending, or to the best of the Borrowers'
knowledge, threatened in writing against any Credit Party that contests its
right to sell or use any such product, process, method, substance, part or other
material which claim or litigation is reasonably likely to have a Material
Adverse Effect.

                    (x) TAXES AND TAX RETURNS.

                    (i) Wang and each of its consolidated Subsidiaries has
         properly completed and timely filed all income tax returns it is
         required to file. The information filed is complete and accurate in all
         material respects. All deductions taken in such income tax returns are
         appropriate and in accordance with applicable laws and regulations,
         except deductions that may have been disallowed but are being
         challenged in good faith and for which adequate reserves have been made
         in accordance with GAAP or other applicable accounting standards in the
         relevant jurisdictions.

                   (ii) All taxes, assessments, fees and other governmental
         charges for periods beginning prior to the date hereof have been timely
         paid (or, if not yet due, adequate reserves therefor have been
         established) and neither Wang

                                      -70-


<PAGE>   77




         nor any of its consolidated Subsidiaries has any material liability
         for taxes in excess of the amounts so paid or reserves so established.

                  (iii) Except as set forth on Schedule 6.1(x), no deficiencies
         for taxes have been claimed, proposed or assessed by any taxing or
         other Governmental Authority against Wang or any of its consolidated
         Subsidiaries and no tax Liens other than liens for current taxes not
         yet due or those being contested in good faith have been filed. There
         are no pending or threatened (in writing) audits, investigations or
         claims for or relating to any liability for taxes and there are no
         matters under discussion with any Governmental Authority which is
         reasonably likely to result in a material additional liability for
         taxes. Either the federal income tax returns of Wang have been audited
         by the Internal Revenue Service and such audits have been closed, or
         the period during which any assessments may be made by the Internal
         Revenue Service has expired without waiver or extension for all years
         up to and including the fiscal year of Wang ended June 30, 1991.

                   (iv) Neither Wang nor any of its Subsidiaries is a party to
         or has any obligation under any written tax sharing agreement or
         agreement regarding payments in lieu of taxes except as set forth on
         Schedule 6.1(x).

                    (y) CORPORATE AND TRADE NAME. Except as set forth on
Schedule 6.1(y), during the past five years, as of the Closing Date no Credit
Party has been known by or used any other corporate or fictitious name.

                    (z) TITLE TO PROPERTY. Each of Wang and its Restricted
Subsidiaries has (i) good and marketable fee simple title to or valid leasehold
interests in all of its real property and (ii) subject to the terms of the
Intellectual Property Security Agreement, good and marketable title to all of
its other property (including, in each case, all real and other property in each
case as reflected in the Financial Statements delivered to the Agent hereunder),
other than properties disposed of in the ordinary course of business or in any
manner otherwise permitted under this Credit Agreement since the date of the
most recent audited consolidated balance sheet of Wang and its Subsidiaries, and
in each case subject to no Liens other than those Liens that are permitted by
Section 7.2(a).

                   (aa) ACCURACY AND COMPLETENESS OF INFORMATION. All factual
information heretofore, contemporaneously or hereafter furnished by or on behalf
of Wang or any of its Subsidiaries in writing to the Agent or any Lender for
purposes of or in connection with this Credit Agreement or any Credit Documents,
or any transaction contemplated hereby or thereby is or will be, to

                                      -71-


<PAGE>   78




the best knowledge of the Borrowers, true and accurate in all material respects
on the date as of which such information is dated or certified and not
incomplete by omitting to state any material fact necessary to make such
information not misleading at such time. Since June 30, 1995, there are no facts
now known to any officer of the Borrowers which, individually or in the
aggregate, is reasonably likely to have a Material Adverse Effect and which have
not been set forth herein, in the Financial Statements, or any certificate,
opinion or other written statement made or furnished by the Borrowers to the
Agent.

                   (ab) AFFILIATE TRANSACTIONS. As of the Closing Date, except
as set forth on Schedule 6.1(ab), neither Wang nor any of its Subsidiaries is a
party to or bound by any agreement or arrangement (whether oral or written) to
which any Affiliate of Wang or any Subsidiary is a party except (i) consistent
with past practices in the ordinary course of and pursuant to the reasonable
requirements of Wang's or such Subsidiary's business or (ii) upon fair and
reasonable terms no less favorable to Wang and such Subsidiary than it could
obtain in a comparable arm'slength transaction with an unaffiliated Person.

                   (ac) NO OTHER INDEBTEDNESS. After giving effect to the
closing of this Credit Agreement, the INET Purchase Agreement and the
transactions contemplated hereby and thereby, neither Wang nor any of its
Restricted Subsidiaries has any Indebtedness other than Indebtedness that is
permitted under Section 7.2(b).

                   (ad) FOREIGN SUBSIDIARIES. A complete list of all Foreign
Subsidiaries and Material Foreign Subsidiaries on the Closing Date is set forth
on Schedule 6.1(ad).

                   (ae) ASSIGNMENT OF CLAIMS ACT. Set forth on Schedule 6.1(ae)
hereto is a complete and accurate list of all effective assignments made with
respect to any of the Accounts of INET under the Assignment of Claims Act of
1940, as amended (31 U.S.C. [Sections] 3727 et seq.).

                   (af) SURVIVAL OF REPRESENTATIONS.  All representations made 
by the Borrowers in this Credit Agreement and in any other Credit Document
executed and delivered in connection herewith

                                      -72-

the transactions contemplated hereby.

Subsidiaries to, (i) maintain its corporate existence (except for the

its Subsidiaries to maintain, public liability insurance, business interruption
insurance, third party property damage insurance and replacement value insurance
on its assets (including the Collateral) under such policies of insurance, with
such insurance companies, in such amounts and covering such risks as are at all
times satisfactory to the Agent in its commercially reasonable judgment. All
policies covering the Collateral are to name the Collateral Agent as an
additional insured and the loss payee in case of loss, and are to contain such
other provisions as the Agent may reasonably require to fully protect the
Collateral Agent's interest in the Collateral and to any payments to be made
under such policies.

                    (g) CASUALTY LOSS. Wang shall provide written notice to the
Agent and the Lenders of the occurrence of any of the following events within
five (5) Business Days after the occurrence of such event: any asset or property
owned or used by any Credit Party is (i) damaged or destroyed, or suffers any
material loss, or (ii) condemned, confiscated or otherwise taken, in whole or in
part, or the use thereof is otherwise diminished so as to render impracticable
or unreasonable the use of such asset or property for the purposes to which such
asset or property were used immediately prior to such condemnation, confiscation
or taking, by exercise of the powers of condemnation or eminent domain or
otherwise, and in either case the amount of the damage, destruction, loss or
diminution to the fair market value of the damaged asset is in excess of
$1,000,000 (collectively, a "CASUALTY LOSS"). Wang shall, and shall cause each
other Credit Party to, diligently file and prosecute its claim or claims for any
award or payment in connection with a Casualty Loss.

                    (h) TAXES. Wang agrees to pay, when due (including by
extension), and to cause each of its Subsidiaries to pay, when due (including by
extension), all taxes and other amounts set forth in Section 6.1(x)(ii) lawfully
levied or assessed against Wang, any of its Subsidiaries or any of the
Collateral before any penalty or interest accrues thereon; PROVIDED, HOWEVER,
that, unless such taxes have become a federal, state, local, foreign tax or
ERISA Lien on any of the assets of Wang or any of its Subsidiaries, no such tax
need be paid if the same is being contested, in good faith, by appropriate
proceedings promptly instituted and diligently conducted and if an adequate
reserve or other appropriate provision shall have been made therefor as required
in order to be in conformity with GAAP or other applicable standards in foreign
jurisdictions.

environmental matters covered by Section 7.1(n), Wang agrees to comply, and to
cause each of its Subsidiaries to comply, with all Requirements of Law
applicable to the Collateral or any part thereof, or to the operation of its
business or its assets generally, unless the Borrowers or such Subsidiary
contest any such Requirements of Law in a reasonable manner and in good faith or
where the failure to comply is not reasonably likely to have a Material Adverse
Effect.

                    (j) USE OF PROCEEDS. The Revolving Loans and Letters of
Credit made to the Borrowers hereunder shall be used by the Borrowers (i) to
refinance the Indebtedness owed by Wang and its Subsidiaries under the Existing
Credit Agreement, (ii) to refinance the Indebtedness owed by INET and its
Subsidiaries under the Existing INET Loan Facility, (iii) for the Borrowers'
general corporate purposes and (iv) to finance a portion of the purchase price
payable by Wang pursuant to the INET Purchase Agreement. The Borrowers shall not
use any portion of the proceeds of any Revolving Loans for the purpose of
purchasing or carrying any "margin stock" (as defined in Regulation G of the
Board of Governors of the Federal Reserve System) in any manner which violates
the provisions of Regulation G or X of said Board of Governors or for any other
purpose in violation of any applicable statute or regulation, or of the terms
and conditions of this Credit Agreement.

                    (k) FISCAL YEAR. Wang agrees to maintain, and to cause each
of its Subsidiaries to maintain, its fiscal year as a year ending June 30,

written consent of the Agent (not to be unreasonably withheld).

7.1(d), Wang agrees to keep, and to cause each of its Subsidiaries to keep, all
property useful and necessary to their respective businesses in good working
order and condition (ordinary wear and tear excepted) in accordance with their
past operating practices and not to commit or suffer any material waste with
respect to any of their properties except to the extent failure to do so is not
reasonably likely to result in a Material Adverse Effect.

                    (m) ERISA DOCUMENTS. The Borrowers will cause to be
delivered to the Agent, upon the Agent's request, each of the following: (i) a
copy of each Plan (or, where any such plan is not in writing, complete

thereof and written descriptions thereof that have been distributed to employees
or former employees of Wang or its Subsidiaries;

                    (n) ENVIRONMENTAL AND OTHER MATTERS.

                    (i) Wang shall, and shall cause each of its Subsidiaries to,
         conduct its business so as to comply in all material respects with all
         applicable Environmental Laws, in all jurisdictions in which any of
         them is doing business, including, without limitation, compliance in
         all material respects with the terms and conditions of all permits and
         governmental authorizations, except to the extent that Wang or any of
         the Subsidiaries are contesting, in good faith by appropriate legal
         proceedings, any such Environmental Law or interpretation thereof or
         application thereof; PROVIDED, FURTHER, that Wang and each of the
         Subsidiaries shall comply in all material respects with the applicable
         order of any court or other governmental agency relating to such
         Environmental Laws unless Wang or the Subsidiaries shall currently be
         prosecuting an appeal or proceedings for review and shall have secured
         a stay of enforcement or execution or other arrangement postponing
         enforcement or execution pending such appeal or proceedings for review.
         If Wang or any of the Subsidiaries shall (A) receive written notice
         that any material violation of any federal, state or local
         Environmental Law may have been committed or is about to be committed
         by Wang or any of the Subsidiaries, (B) receive written notice that any
         administrative or judicial complaint or order has been filed or is
         about to be filed against Wang or any of the Subsidiaries alleging
         material violations of any federal, state or local Environmental Law,
         or requiring Wang or any of the Subsidiaries to take any action in
         connection with the release of toxic or hazardous substances into the
         environment or (C) receive any written notice from a federal, state, or
         local governmental agency or private party alleging that Wang or any of
         the Subsidiaries may be liable or responsible for material costs
         associated with a response to or cleanup of a release of a toxic or
         hazardous substance into the environment or any damages caused

                                      -81-


<PAGE>   88




         thereby, Wang shall provide the Agent and the Lenders with a copy of
         such notice within ten (10) days after the receipt thereof by the
         Borrowers or any of the Subsidiaries. Within ten (10) days after the
         Borrowers learn of the enactment or promulgation of any federal, state
         or local Environmental Law, which is reasonably likely to have a
         Material Adverse Effect, Wang shall provide the Agent and the Lenders
         with notice thereof. The Borrowers shall promptly take all reasonable
         actions necessary to prevent the imposition of any Liens on any of its
         properties arising out of or related to any environmental matters. At
         the request of the Agent, Wang shall provide the Agent with any
         additional information relating to environmental matters and any
         potential related liability resulting therefrom as the Agent may
         reasonably request.

                   (ii) For purposes of this Section 7.1(n), "material" means
         any noncompliance or basis of liability that is reasonably likely to
         subject Wang or any of its Subsidiaries to liability in excess of
         $10,000,000.

                    (o) SECURITY INTERESTS. Wang will defend, and will cause
each other Credit Party to defend, the Collateral against all claims and demands
of all Persons at any time claiming the same or any interest therein, other than
claims relating to Liens permitted by the Credit Documents. Wang agrees to
comply, and will cause each other Credit Party to comply, with the requirements
of all provincial, state and federal laws in order to grant to the Lenders valid
and perfected first security interests in the Collateral.

                    (p) PATENTS AND TRADEMARKS. Wang shall do or cause to be
done all things necessary to preserve and keep in full force and effect all of
its and its Restricted Subsidiaries' material patents and applications and
registrations and applications of trademarks, service marks and other marks,
trade names (other than the "Bull" tradename) or other similar registered
property except (i) as otherwise permitted pursuant to the Intellectual Property
Security Agreement or (ii) those the failure to preserve and keep in full force
and effect is not reasonably likely to have a Material Adverse Effect.

                    (q) FURTHER ASSURANCES. Wang shall take, and shall cause
each of its Subsidiaries to take, all such further actions and execute all such
further documents and instruments as the Agent may at any time reasonably
determine in its sole discretion to be necessary or desirable to further carry
out and consummate the transactions contemplated by the Credit Documents, to
cause the execution, delivery and performance of the Credit Documents to be duly
authorized and to perfect or protect the Liens (and the priority status thereof)
of the Collateral Agent for the benefit of the Lenders on the Collateral.

                    (r) COLLATERAL ACCESS AGREEMENTS. Wang shall use its
reasonable best efforts (which shall not require a substantial expenditure of
funds) to deliver to the Agent a Collateral Access Agreement with respect to
each Material Location in existence on the Closing Date, duly executed by the
landlord of such Material Location and the applicable Credit Party. Prior to the
date on which any other location listed on Schedule 6.1(k) becomes a Material
Location, Wang shall use its reasonable best efforts (which shall not require a
substantial expenditure of funds) to deliver to the Agent a Collateral Access
Agreement with respect to each such location, duly executed by the landlord of
such location and the applicable Credit Party.

                    (s) PLEDGE OF STOCK IN FOREIGN SUBSIDIARIES.

                    (i) Promptly upon receipt by Wang of a written notice from
         the Agent stating that the Agent has determined, in its reasonable
         judgment, that there exists a Foreign Subsidiary not listed on Schedule
         6.1(ad) that is material, Wang shall, or shall cause its Subsidiaries
         (other than its Foreign Subsidiaries) to, pledge to the Collateral
         Agent for the ratable benefit of the Lenders all of the issued and
         outstanding shares of capital stock of such Foreign Subsidiary pursuant

                  tax described in Sections 406 of ERISA or 4975 of the Internal
                  Revenue Code for which a statutory or class exemption is not
                  available or a private exemption has not been previously
                  obtained from the Department of Labor, other than any civil

                  Material Adverse Effect;

                          (ii) permit to exist with respect to any Benefit Plan
                  any accumulated funding deficiency (as defined in Sections 302

                  would result in any liability of Wang, any Subsidiary or any
                  ERISA Affiliate under Title IV of ERISA, other than any
                  liability that is not reasonably likely to have a Material
                  Adverse Effect;

                           (v) fail to make any required contribution or payment

                           (vii) amend a Plan resulting in an increase in
                  current liability for the plan year such that either of Wang,
                  any Subsidiary or any ERISA Affiliate is required to provide
                  security to such Plan under Section 401(a)(29) of the Internal
                  Revenue Code; or

                          (viii) withdraw from any Multiemployer Plan where
                  such withdrawal is reasonably likely to result in any
                  liability of any such entity under Title IV of ERISA, other
                  than any liability that is not reasonably likely to have a
                  Material Adverse Effect.

                  (v) BUSINESS OF CERTAIN SUBSIDIARIES. Wang shall not permit

         shall not permit any other Credit Party, to maintain or keep Inventory
         and Equipment having an aggregate book value in excess of $500,000 at
         any location that is not set forth on Schedule 6.1(k).

Expenses or other Obligations (other than principal) when due or within three
(3) Business Days of when due, whether at stated maturity, by acceleration, or
otherwise or (ii) any principal when due, whether at stated maturity, by
acceleration or otherwise; or

                  (b) any representation or warranty made by any Credit Party
under or in connection with any Credit Document shall prove to have been
incorrect in any material respect when made or deemed made; or

                  (c) the Borrowers or any Restricted Subsidiary shall fail to

term, covenant or agreement contained in any Credit Document (other than as set
forth in Sections 8.1(a) and (c)) on its part to be performed or observed or any
Borrower or any Subsidiary shall fail to comply with any provisions contained in

Business Days after notice from the Agent to the Borrowers; or

                    (e) any Borrower or any Restricted Subsidiary (i) shall fail
to pay any Indebtedness in an amount in excess of $3,000,000 (including the
Subordinated Notes but excluding disputed trade Indebtedness in the ordinary
course of business and the Indebtedness hereunder) when due (whether at
scheduled maturity or by required prepayment, acceleration, demand or
otherwise), or (ii) shall otherwise be in breach or default in any of its
obligations under any agreement with respect to any such Indebtedness, if the
effect of such failure to pay, breach or default is to cause such Indebtedness
to become due or redeemed or permit the holder or holders of such Indebtedness
(or a trustee or agent on behalf of such holder or holders) to declare such
Indebtedness due or require such Indebtedness to be redeemed prior to its stated
maturity; or

                    (f) any Credit Party shall dissolve, wind up or otherwise
cease its business; or

                    (g) any Borrower or any Restricted Subsidiary shall become
the subject of (i) an Insolvency Event as set forth in clause (e) of the

(60) days or (ii) any Insolvency Event except as set forth in clause (e) of the
definition of Insolvency Event; or

                    (h) any judgment or order for the payment of money in excess
of $5,000,000 shall be rendered against Wang or any Restricted Subsidiary and
either (i) enforcement proceedings shall have been commenced by any creditor
upon such judgment or order or (ii) there shall be any period of thirty (30)
consecutive days during which a stay of enforcement of such judgment or order,
by reason of a pending appeal or otherwise, shall not be in effect; PROVIDED
that in the case of any such judgment or order with respect to a Subsidiary that
is not a Credit Party, such judgment or order shall have a Material Adverse
Effect; or

<PAGE>   106




                    (i) any non-monetary judgment or order shall be rendered
against the Borrowers or any Subsidiary that is reasonably likely to have a
Material Adverse Effect, and there shall be any period of 30 consecutive days
during which a stay of enforcement of such judgment or order, by reason of a
pending appeal or otherwise, shall not be in effect; or

                    (j) except through the action or inaction of the Agent or
any Lender, any covenant, agreement or obligation of any Credit Party contained
in or evidenced by any of the Credit Documents shall cease to be enforceable, or
shall be determined to be unenforceable, in accordance with its terms; any
Credit Party shall deny or disaffirm its obligations under any of the Credit
Documents or any Liens granted in connection therewith; or any Liens granted in
any of the Collateral shall be determined to be void, voidable or invalid, are
subordinated or are not given the priority contemplated by this Credit
Agreement; or

                    (k) except through the action or inaction of the Collateral
Agent or any Lender, a Collateral Document shall for any reason (other than
pursuant to the terms thereof) cease to create a valid and, except as otherwise
permitted under Section 7.2(a), perfected first priority Lien on the Collateral
purported to be covered thereby; or

                    (l) a Change in Control shall have occurred.

                    SECTION 8.2. ACCELERATION AND CASH COLLATERALIZATION. Upon
the occurrence and during the continuance of an Event of Default, the Agent may
take any or all of the following actions, without prejudice to the rights of the
Agent or any Lender to enforce its claims against the Borrowers:

                    (a) ACCELERATION. Upon the written request of the Majority
Lenders, and by delivery of written notice to the Borrowers from the Agent, all
Obligations shall be declared to be immediately due and payable (except with
respect to any Event of Default with respect to a Credit Party set forth in
Section 8.1(g), in which case all Obligations shall automatically become
immediately due and payable without the necessity of any request of the Majority
Lenders or notice or other demand to the Borrowers) without presentment, demand,
protest or any other action or obligation of the Agent or any Lender, all of
which are hereby expressly waived by the Borrowers.

                    (b) TERMINATION OF COMMITMENTS. Upon the written request of
the Majority Lenders, and by delivery of written notice to the Borrowers from
the Agent, the Commitments shall be immediately terminated and, at all times
thereafter, all Revolving Loans made by any Lender pursuant to this Credit
Agreement shall be at such Lender's sole discretion, unless such

                                      -100-


<PAGE>   107




Event of Default is cured or waived in accordance with Section 10.11.

                  (c) CASH COLLATERALIZATION. On demand of the Agent or the
Majority Lenders, the Borrowers shall immediately deposit with the Collateral
Agent for each Letter of Credit then outstanding, cash or Cash Equivalents in an
amount equal to 105% of the greatest amount drawable thereunder and execute and
deliver documentation with respect to such cash collateralization in form and
substance satisfactory to the Collateral Agent.

                  SECTION 8.3. RESCISSION OF ACCELERATION. After acceleration of
the maturity of the Revolving Loans, if the Borrowers pay all accrued interest
and all principal due (other than by reason of the acceleration) and all
Defaults and Events of Default are otherwise remedied or waived in accordance
with Section 10.11, the Majority Lenders may elect in their sole discretion, to
rescind the acceleration and return any cash collateral. (This Section is
intended only to bind all of the Lenders to a decision of the Majority Lenders
and not to confer any right on the Borrowers, even if the described conditions
for the Majority Lenders' election may be met.)

                  SECTION 8.4. REMEDIES. Upon the occurrence and during the
continuance of an Event of Default, the Agent, the Collateral Agent and the
Lenders shall have all rights and remedies with respect to the Obligations under
the Credit Documents and the Collateral available to it as creditors under
applicable law and the Credit Documents and the Agent and, to the fullest extent
permitted by applicable law, the Collateral Agent may do any or all of the
following:

                  (a) remove for copying all documents, instruments, files and
         records (including the copying of any computer records) relating to the
         Accounts or use (at the expense of the Borrowers) such supplies or
         space of any Credit Party at such Credit Party's place of business
         necessary to properly administer and collect the Accounts thereon;

                  (b) accelerate or extend the time of payment, compromise,
         issue credits, or bring suit on the Accounts (in the name of the
         Borrowers or the Lenders) and otherwise administer and collect the
         Accounts;

                  (c) sell, assign and deliver the Accounts and any returned,
         reclaimed or repossessed merchandise, with or without advertisement, at
         public or private sale, for cash, on credit or otherwise, subject to
         applicable law; and

                  (d) foreclose the security interests created pursuant to the 
         Credit Documents by any available procedure, or take possession of any 
         or all of the Collateral without judicial

                                      -101-


<PAGE>   108




         process and enter any premises where any Collateral may be located for
         the purpose of taking possession of or removing the same.

Any Lender may bid or become a purchaser at any sale, free from any right of
redemption, which right is expressly waived by the Borrowers. If notice of
intended disposition of any Collateral is required by law, it is agreed that
fifteen (15) Business Days notice shall constitute reasonable notification. Wang
will assemble, and cause each other Credit Party to assemble the Collateral and
make it available to the Collateral Agent at such locations as the Agent may
specify, whether at the premises of such Credit Party or elsewhere, and will
make available to the Collateral Agent the premises and facilities of such
Credit Party for the purpose of the Collateral Agent's taking possession of,
removing or putting the Collateral in saleable form.

                  SECTION 8.5. RIGHT OF SETOFF. In addition to and not in
limitation of all rights of offset that any Lender or the Issuing Bank may have
under applicable law, upon the occurrence of any Event of Default, and whether
or not any Lender or the Issuing Bank has made any demand or the Obligations of
any Credit Party have matured, each Lender and the Issuing Bank shall have the
right to appropriate and apply to the payment of the Obligations of a Credit
Party all deposits and other obligations then or thereafter owing by such Lender
or the Issuing Bank to such Credit Party. Each Lender or the Issuing Bank
exercising such rights shall notify the Agent thereof (and the Agent shall
promptly notify the Borrowers thereof) and any amount received as a result of
the exercise of such rights shall be shared in accordance with Section 2.7.

                  SECTION 8.6. LICENSE FOR USE OF SOFTWARE AND OTHER
INTELLECTUAL PROPERTY. Unless expressly prohibited by the licensor thereof, if
any, the Agent and the Collateral Agent are hereby granted a limited
non-exclusive non-transferable license to use all computer software programs,
data bases, processes and materials used by any Borrower and any Subsidiary in
connection with its businesses or in connection with the Collateral solely in
connection with the exercise of remedies under this Credit Agreement and the
other Credit Documents. The Agent and the Collateral Agent agree not to use any
such license prior to the occurrence of an Event of Default.

                  SECTION 8.7. NO MARSHALLING; DEFICIENCIES; REMEDIES
CUMULATIVE. The net cash proceeds resulting from the Agent's or the Collateral
Agent's exercise of any of the foregoing rights to liquidate all or
substantially all of the Collateral (after deducting all of the Agent's and the
Collateral Agent's Expenses related thereto) shall be applied by the Agent to
the payment of the Obligations to the Agent, the Collateral Agent and the
Lenders, whether due or to become due, in such order as the Agent

                                      -102-


<PAGE>   109




may elect. The Borrowers, jointly and severally, shall remain liable to the
Agent, the Collateral Agent and the Lenders for any deficiencies, and the Agent,
the Collateral Agent and the Lenders in turn agree to remit to the Borrowers or
their respective successors or assigns, any surplus resulting therefrom. The
foregoing remedies are not intended to be exhaustive and the full or partial
exercise of any of them shall not preclude the full or partial exercise of any
other available remedy under this Credit Agreement, under any other Credit
Document, at equity or at law.

                                   ARTICLE IX

                       THE AGENT AND THE COLLATERAL AGENT

                  SECTION 9.1. APPOINTMENT OF AGENT AND COLLATERAL AGENT.

                  (a) Each Lender hereby designates BTCO as the Agent and BTCC
as the Collateral Agent and irrevocably authorizes the Agent and the Collateral
Agent to take action on such Lender's behalf under the Credit Documents and to
exercise the powers and to perform the duties described therein and to exercise
such other powers as are reasonably incidental thereto. Each Agent may perform
any of its duties by or through its agents or employees.

                  (b) Other than the Borrowers' rights under Section 9.9, the
provisions of this Article IX are solely for the benefit of each Agent and the
Lenders, and none of the Credit Parties shall have any rights as a third party
beneficiary of any of the provisions hereof. Each Agent shall act solely as
agent of the Lenders and assumes no obligation toward or relationship of agency
or trust with or for any Credit Party.

                  (c) As used in this Article IX and unless the context
otherwise requires, the term "Agent" shall refer to each of BTCo in its capacity
as Agent and BTCC in its capacity as Collateral Agent.

                  SECTION 9.2. NATURE OF DUTIES OF AGENT. Each Agent shall have
no duties or responsibilities except those expressly set forth in the Credit
Documents. Neither Agent nor any of its officers, directors, employees or agents
shall be liable for any action taken or omitted by it as such hereunder or in
connection herewith, unless caused by its or their gross negligence or willful
misconduct. The duties of each Agent shall be mechanical and administrative in
nature. Each Agent shall not have a fiduciary relationship in respect of any
Lender or any participant of any Lender.

                  SECTION 9.3. LACK OF RELIANCE ON AGENT.

                  (a) Independently and without reliance upon either Agent, each
Lender, to the extent it deems appropriate, has made and shall continue to make
(i) its own independent investigation of the financial or other condition and
affairs of each Credit Party in connection with the taking or not taking of any
action in connection herewith and (ii) its own appraisal of the creditworthiness
of each Credit Party, and, except as expressly provided in this Credit
Agreement, each Agent shall have no duty or responsibility, either initially or
on a continuing basis, to provide any Lender with any credit or other
information with respect thereto, whether coming into its possession before the
making of the Loans or at any time or times thereafter.

                  (b) Each Agent shall not be responsible to any Lender for any
recitals, statements, information, representations or warranties herein or in
any document, certificate or other writing delivered in connection herewith or
for the execution, effectiveness, genuineness, validity, enforceability,
collectibility, priority or sufficiency of this Credit Agreement or the
Revolving Notes or the financial or other condition of any Credit Party. Each
Agent shall not be required to make any inquiry concerning either the
performance or observance of any of the terms, provisions or conditions of this
Credit Agreement or the Revolving Notes, or the financial condition of any
Credit Party, or the existence or possible existence of any Default or Event of
Default, unless specifically requested to do so in writing by any Lender.

                  SECTION 9.4. CERTAIN RIGHTS OF THE AGENT. Each Agent may
request instructions from the Majority Lenders at any time. If either Agent
requests instructions from the Majority Lenders with respect to any action or
inaction, such Agent shall be entitled to await instructions from the Majority
Lenders before such action or inaction. No Lender shall have any right of action
based upon either Agent's action or inaction in response to instructions from
the Majority Lenders.

                  SECTION 9.5. RELIANCE BY AGENT. Each Agent may rely upon
written or telephonic communication it believes to be genuine and to have been
signed, sent or made by the proper person. Each Agent may obtain the advice of
legal counsel (including counsel for the Borrowers with respect to matters
concerning the Borrowers), independent public accountants and other experts
selected by it and shall have no liability for any action or inaction taken or
omitted to be taken by it in good faith based upon such advice.

<PAGE>   111




                  SECTION 9.6. INDEMNIFICATION OF AGENT. To the extent either
Agent is not reimbursed and indemnified by the Borrowers, each Lender will
reimburse and indemnify such Agent, to the extent of its Proportionate Share for
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses (including counsel fees and disbursements) or
disbursements of any kind or nature whatsoever (including all Expenses) which
may be imposed on, incurred by or asserted against such Agent in performing its
duties hereunder or otherwise relating to the Credit Documents unless resulting
from such Agent's gross negligence or willful misconduct. The agreements
contained in this Section shall survive any termination of this Credit Agreement
and the other Credit Documents and the payment in full of the Obligations.

                  SECTION 9.7. THE AGENT IN ITS INDIVIDUAL CAPACITY. In its
individual capacity, each Agent shall have the same rights and powers hereunder
as any other Lender or holder of a Revolving Note or participation interests and
may exercise the same as though it was not performing the duties specified
herein. The terms "Lenders," "Majority Lenders," "holders of Revolving Notes,"
or any similar terms shall, unless the context clearly otherwise indicates,
include each Agent in its individual capacity. Each Agent and its Affiliates may
accept deposits from, lend money to, acquire equity interests in, and generally
engage in any kind of banking, trust, financial advisory or other business with
the Borrowers or any Affiliate of the Borrowers as if it were not performing the
duties specified herein, and may accept fees and other consideration from the
Borrowers for services in connection with this Credit Agreement and otherwise
without having to account for the same to the Lenders.

                  SECTION 9.8. HOLDERS OF REVOLVING NOTES. Each Agent may deem
and treat the payee of any Revolving Note as the owner thereof for all purposes
hereof unless and until a written notice of the assignment or transfer thereof
shall have been filed with each Agent. Any request, authority or consent of any
Person who, at the time of making such request or giving such authority or
consent, is the holder of any Revolving Note, shall be conclusive and binding on
any subsequent holder, transferee or assignee of such Revolving Note or of any
Revolving Note or Revolving Notes issued in exchange therefor.

                  SECTION 9.9.  SUCCESSOR AGENT.

                  (a) Either or both Agents may, upon ten (10) Business Days'
notice to the Lenders and the Borrowers, resign by giving written notice thereof
to the Lenders and the Borrowers. An Agent's resignation shall be effective upon
the appointment of a successor Agent. Such resignation of an Agent shall be
deemed to be a resignation of Bankers Trust Company as Issuing Bank.

                  (b) Upon receipt of either Agent's resignation, the Majority
Lenders may appoint a successor Agent which shall also be a Lender. Unless an
Event of Default shall have occurred and be continuing at the time of such
appointment, the successor Agent shall be subject to approval by the Borrowers,
which approval shall not be unreasonably withheld and if the Borrower approves
of the successor Agent, such approval shall be delivered to the Majority Lenders
within five (5) Business Days after the Borrowers' receipt of notice of a
proposed successor Agent. If a successor Agent has not accepted its appointment
within fifteen (15) Business Days, then the retiring Agent may, on behalf of the
Lenders, appoint a successor Agent.

                  (c) Upon its acceptance of the agency hereunder, such
successor Agent shall succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties and obligations under this Credit Agreement. The
retiring Agent shall continue to have the benefit of this Article IX for any
action or inaction while it was Agent.

                  SECTION 9.10. COLLATERAL MATTERS.

                  (a) Each Lender authorizes and directs each Agent to enter
into the Collateral Documents for the benefit of the Lenders. Except as
otherwise set forth herein, any action or exercise of powers by the Majority
Lenders under the Credit Documents, together with such other powers as are
reasonably incidental thereto, shall be authorized and binding upon all of the
Lenders. Prior to an Event of Default, without notice to or consent from any
Lender, either Agent may take any action necessary or advisable to perfect and
maintain the perfection of the Liens upon the Collateral.

                  (b) Each Agent is authorized to release any Lien granted to or
held by such Agent upon any Collateral (i) upon termination of the Commitments
and payment and satisfaction of all of the Obligations, (ii) required to be
delivered in connection with permitted sales of Collateral hereunder, if any,
upon receipt of the proceeds or (iii) if the release can be and is approved by
the Majority Lenders or all Lenders, as applicable. Each Agent may request and
the Lenders will provide confirmation of such Agent's authority to release
particular types or items of Collateral.

                  (c) Upon any sale and transfer of Collateral which is
expressly permitted pursuant to the terms of this Credit Agreement, or consented
to in writing by the Majority Lenders or all of the Lenders, as applicable, and
upon at least five (5) Business Days' prior written request by the Borrowers,
either Agent shall (and is hereby irrevocably authorized by the Lenders to)
execute such documents as may be necessary to evidence the

                                      -106-


<PAGE>   113




release of the Liens granted to such Agent for the benefit of the Lenders herein
or pursuant hereto upon the Collateral that was sold or transferred; PROVIDED
that (i) each Agent shall not be required to execute any such document on terms
which, in such Agent's opinion, would expose such Agent to liability or create
any obligation of such Agent or entail any adverse consequence to such Agent
other than the release of such Liens without recourse or warranty and (ii) such
release shall not in any manner discharge, affect or impair the Obligations or
any Liens upon (or obligations of the Borrowers or any Subsidiary in respect of)
all interests retained by the Borrowers or any Subsidiary, including (without
limitation) the proceeds of the sale, all of which shall continue to constitute
part of the Collateral. In the event of any sale or transfer of Collateral, or
any foreclosure with respect to any of the Collateral, each Agent shall be
authorized to deduct all of the Expenses reasonably incurred by such Agent from
the proceeds of any such sale, transfer or foreclosure.

                  (d) Neither Agent shall have any obligation to assure that the
Collateral exists or is owned by the Borrowers or any Subsidiary, that such
Collateral is cared for, protected or insured, or that the Liens in the
Collateral have been created, perfected, or have any particular priority. With
respect to the Collateral, each Agent may act in any manner it may deem
appropriate, in its sole discretion, given such Agent's own interest in the
Collateral as one of the Lenders and it shall have no duty or liability
whatsoever to the Lenders, except for its gross negligence or willful
misconduct.

                  SECTION 9.11. ACTIONS WITH RESPECT TO DEFAULTS. In addition to
each Agent's right to take actions on its own accord as permitted under this
Credit Agreement, each Agent shall take such action with respect to a Default or
Event of Default as shall be directed by the Majority Lenders or all Lenders, as
applicable. Until an Agent shall have received such directions, such Agent may
act or not act as it deems advisable and in the best interests of the Lenders.

                  SECTION 9.12. DELIVERY OF INFORMATION. Each Agent shall not be
required to deliver to any Lender originals or copies of any documents,
instruments, notices, communications or other information received by such Agent
from the Borrowers, any Subsidiary, the Majority Lenders, any Lender or any
other Person under or in connection with this Credit Agreement or any other
Credit Document except (i) as specifically provided in this Credit Agreement or
any other Credit Document and (ii) as specifically requested from time to time
in writing by any Lender with respect to a specific document, instrument, notice
or other written communication received by and in the possession of such Agent
at the time of receipt of such request and then only in accordance with such
specific request.

                  SECTION 10.8. ASSIGNMENTS AND PARTICIPATIONS.

                  (a) BORROWER ASSIGNMENT. The Borrowers shall not assign this
Credit Agreement or any rights or obligations hereunder, without the prior
written consent of the Agent and the Lenders.

                  (b) LENDER ASSIGNMENTS. Each Lender may assign to one or more
banks or other financial institutions all or a portion of its rights and
obligations under this Credit Agreement, the Revolving Notes and the other
Credit Documents, with the consent of the Agent, and with the consent of Wang
(not to be unreasonably withheld), and upon execution and delivery to the Agent,
for its acceptance and recording in the Register, of an agreement in
substantially the form of Exhibit N (an "ASSIGNMENT AND ASSUMPTION AGREEMENT"),
together with surrender of any Revolving Note or Revolving Notes subject to such
assignment and a processing and recordation fee of $2,500.00. No such assignment
shall be for less than $5,000,000 of the Commitments unless it is to another
Lender. Upon such execution and delivery of the Assignment and Assumption
Agreement to the Agent, from and after the date specified as the effective date
in the Assignment and Assumption Agreement (the "ACCEPTANCE DATE"), (x) the
assignee thereunder shall be a party hereto, and, to the extent that rights and
obligations hereunder have been assigned to it pursuant to such Assignment and
Assumption Agreement, such assignee shall have the rights and obligations of a
Lender hereunder and (y) the assignor thereunder shall, to the extent that
rights and obligations hereunder have been assigned by it pursuant to such
Assignment and Assumption Agreement, relinquish its rights (other than any
rights it may have pursuant to Section 10.10 which will survive) and be released
from its obligations under this Credit Agreement (and, in the case of an
Assignment and Assumption Agreement covering all or the remaining portion of an
assigning Lender's rights and obligations under this Credit Agreement, such
Lender shall cease to be a party hereto). (This Section does not apply to
branches and Affiliates of a Lender, it being understood that a Lender may make,
carry or transfer Revolving Loans at or for the account of any of its branch
offices or Affiliates without consent of the Borrowers, the Agent or any Lender
and without payment of any processing and recordation fee.)

                  By executing and delivering an Assignment and Assumption
Agreement, the assignee thereunder confirms and agrees as follows: (i) other
than as provided in such Assignment and Assumption Agreement, the assigning
Lender makes no representation or warranty and assumes no responsibility with

                                      -110-


<PAGE>   117



respect to any statements, warranties or representations made in or in
connection with this Credit Agreement or the execution, legality, validity,
enforceability, genuineness, sufficiency or value of this Credit Agreement, the
Revolving Notes or any other instrument or document furnished pursuant hereto,
(ii) such assigning Lender makes no representation or warranty and assumes no
responsibility with respect to the financial condition of the Borrowers or any
other Credit Parties or the performance or observance by the Borrowers or any
other Credit Parties of any of their obligations under this Credit Agreement or
any other instrument or document furnished pursuant hereto, (iii) such assignee
confirms that it has received a copy of this Credit Agreement, together with
copies of the Financial Statements referred to in Section 6.1(i), the Financial
Statements delivered pursuant to Section 7.1(a), if any, and such other
documents and information as it has deemed appropriate to make its own credit
analysis and decision to enter into such Assignment and Assumption Agreement,
(iv) such assignee will, independently and without reliance upon the Agent, such
assigning Lender or any other Lender and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit
decisions in taking or not taking action under this Credit Agreement, (v) such
assignee appoints and authorizes the Agent to take such action as agent on its
behalf and to exercise such powers under this Credit Agreement as are delegated
to the Agent by the terms hereof, together with such powers as are reasonably
incidental thereto and (vi) such assignee agrees that it will perform in
accordance with their terms all of the obligations which by the terms of this
Credit Agreement are required to be performed by it as a Lender.

                  (c) AGENT'S REGISTER. The Agent shall maintain a register of
the names and addresses of the Lenders, their Commitments, and the principal
amount of their Revolving Loans (the "REGISTER"). The Agent shall also maintain
a copy of each Assignment and Assumption Agreement delivered to and accepted by
it and modify the Register to give effect to each Assignment and Assumption
Agreement. The entries in the Register shall be conclusive and binding for all
purposes, absent manifest error, and the Borrowers, the Agent and the Lenders
may treat each Person whose name is recorded in the Register as a Lender
hereunder for all purposes of this Credit Agreement. The Register and copies of
each Assignment and Assumption Agreement shall be available for inspection by
the Borrowers or any Lender at any reasonable time and from time to time upon
reasonable prior notice. Upon its receipt of each Assignment and Assumption
Agreement and surrender of the affected Revolving Note or Revolving Notes
subject to such assignment, the Agent will give prompt notice thereof to the
Borrowers. Within five (5) Business Days after its receipt of such notice, each
Borrower shall execute and deliver to the Agent a new Revolving Note or
Revolving Notes to the order of the assignee in the amount of the

                                      -111-


<PAGE>   118


Commitment or Commitments assumed by it and to the assignor in the amount of the
Commitment or Commitments retained by it, if any. Such new Revolving Note or
Revolving Notes shall reevidence the indebtedness outstanding under the
surrendered Revolving Note or Revolving Notes and shall be in an aggregate
principal amount equal to the aggregate principal amount of such surrendered
Revolving Note or Revolving Notes, shall be dated as of the Closing Date. The
Agent shall return to the Borrowers the affected Revolving Note or Notes
surrendered to the Agent marked "cancelled" or, if any such note cannot be
located, an affidavit to such effect. The Agent shall be entitled to rely upon
the Register exclusively for purposes of identifying the Lenders hereunder.

                  (d) LENDER PARTICIPATIONS. Each Lender may sell participations
(without the consent of the Agent, the Borrowers or any other Lender) to one or
more banks or other financial institutions in or to all or a portion of its
rights and obligations under this Credit Agreement, the Revolving Notes and the
other Credit Documents. Notwithstanding a Lender's sale of a participation
interest, such Lender's obligations hereunder shall remain unchanged. The
Borrowers, the Agent, and the other Lenders shall continue to deal solely and
directly with such Lender. No participant shall have rights to approve any
amendment or waiver of this Credit Agreement except to the extent such amendment
or waiver would (i) increase the Commitment of the Lender from whom the
participant purchased its participation interest, if such increase would cause
such participant's obligations to increase; (ii) reduce the principal of, or
rate or amount of interest on the Revolving Loans subject to such participation;
(iii) postpone any date fixed for any payment of principal of, or interest on,
the Revolving Loans subject to the participation interest; or (iv) release all
or a substantial portion of the Collateral, other than in each case when
otherwise permitted hereunder. A participant shall be entitled to the benefits
of Sections 4.8(d), 4.9 and 4.10 only up to a maximum amount for each section
equal to the maximum amount for each section which the Lender from whom it
acquired its participation would have been entitled if it had not sold the
participation.

                  Each Lender agrees that, without the prior written consent of
Wang and the Agent, it will not make any assignment hereunder in any manner or
under any circumstances that would require registration or qualification of, or
filings in respect of, any Loan, Revolving Note or other Obligation under the
securities laws of the United States or of any jurisdiction.

                  (e) CONFIDENTIALITY. In connection with their efforts to
assign its rights or obligations or sell participations pursuant to Sections
10.8(b) and (d) hereof, the Agent or the Lenders may disclose any information
they have, now or in the future, with respect to the business of the Borrowers
or the

                                      -112-

Acquisition of the Acquired INET Stock to prospective assignees or purchasers,
provided that such prospective assignees or purchasers agree to be bound by the
provisions of Section 10.9.

                  SECTION 10.9. CONFIDENTIALITY. Except as provided in Section
10.8(e), each Lender agrees that it will not disclose, without the prior consent
of the Borrowers, any information with respect to the Borrowers or any
Subsidiary which is furnished pursuant to this Credit Agreement and which is
designated by the Borrowers to the Lenders in writing as confidential (the
information delivered pursuant to Sections 7.1(a), (b), (c) and (e) and 8.4(a)
being hereby so designated), and acknowledges that such information, except as
provided below, is material non-public information about the Borrowers and their
consolidated Subsidiaries PROVIDED, THAT any Lender may disclose any such
information (a) to its Affiliates, employees, auditors, or counsel, or to
another Lender if the disclosing Lender or such disclosing Lender's holding or
parent company in its reasonable discretion determines that any such party
should have access to such information provided that each such person will be
advised of the confidential nature of such information, (b) as has become
generally available to the public other than through improper disclosure by the
Agent or any Lender, (c) as may be required or appropriate in any report,
statement or testimony submitted to any Governmental Authority having or
claiming to have jurisdiction over such Lender, (d) as may be required or
appropriate in response to any summons or subpoena or in connection with any
litigation, PROVIDED that Wang is given prior or contemporaneous notice of such
disclosure and (e) in order to comply with any Requirement of Law.

                  SECTION 10.10. INDEMNIFICATION; REIMBURSEMENT OF EXPENSES OF
COLLECTION.

                  (a) The Borrowers, jointly and severally, hereby indemnify and
agree to defend and hold harmless the Agent, the Collateral Agent, the Issuing
Bank and each of the Lenders and their respective directors, officers, agents,
employees and counsel (each, an "Indemnified Party") from and against any and
all losses, claims, damages, liabilities, deficiencies, judgments or expenses
incurred by any of them (except to the extent that it is finally judicially
determined to have resulted from their own gross negligence or willful
misconduct) arising out of or by reason of (i) any litigations, investigations,
claims or proceedings which arise out of or are in any way related to (A) this
Credit Agreement, any other Credit Document or the transactions contemplated
hereby or thereby including, without limitation, the transactions contemplated
by the INET Purchase Agreement, (B) the issuance of the Letters of Credit, (C)
the failure of the Issuing Bank to honor a drawing under any Letter of Credit,
as a result of any act or omission, whether rightful or wrongful, of any present
or future de jure or de facto

                                      -113-

government or Governmental Authority, (D) any actual or proposed use by the
Borrowers of the proceeds of the Revolving Loans or (E) the Agent's, the
Collateral Agent's or the Lenders' entering into this Credit Agreement, the
other Credit Documents or any other agreements and documents relating hereto,
including, without limitation, amounts paid in settlement, court costs and the
reasonable fees and disbursements of counsel incurred in connection with any
such litigation, investigation, claim or proceeding or any advice rendered in
connection with any of the foregoing and (ii) any remedial or other action taken
by the Borrowers, the Agent, the Collateral Agent or any of the Lenders in
connection with compliance by the Borrowers or any Subsidiary, or any of their
respective properties, with any federal, state or local Environmental Laws. In
addition, the Borrowers shall, upon demand, pay to the Agent all costs and
expenses incurred by the Agent (including the reasonable fees and disbursements
of counsel and other professionals) in connection with the preparation,
execution, delivery, administration, modification and amendment of the Credit
Documents, and pay to the Agent, the Collateral Agent and any Lender all costs
and expenses (including the reasonable fees and disbursements of counsel and
other professionals) paid or incurred by the Agent, the Collateral Agent or such
Lender in (A) enforcing or defending its rights under or in respect of this
Credit Agreement, the other Credit Documents or any other document or instrument
now or hereafter executed and delivered in connection herewith, (B) in
collecting the Obligations, (C) in foreclosing or otherwise collecting upon the
Collateral or any part thereof and (D) obtaining any legal, accounting or other
advice in connection with any of the foregoing. If and to the extent that the
Obligations of the Borrowers hereunder are unenforceable for any reason, the
Borrowers, jointly and severally, hereby agree to make the maximum contribution
to the payment and satisfaction of such Obligations which is permissible under
applicable law.

                  (b) The Borrowers' Obligations under Sections 4.8(d), 4.9,
4.10, 9.6 and this Section 10.10 shall survive any termination of this Credit
Agreement and the other Credit Documents and the payment in full of the
Obligations, and are in addition to, and not in substitution of, any other of
their Obligations set forth in this Credit Agreement.

                  SECTION 10.11. AMENDMENTS AND WAIVERS.

                  (a) No amendment or waiver of any provision of this Credit
Agreement or any other Credit Document shall be effective unless in writing and
signed by the Majority Lenders (or by the Agent on their behalf with the consent
of the Majority Lenders) and the Borrowers, except that:

                  (i) the consent of all the Lenders is required to (A) reduce
         the principal of, or interest on, the Revolving

         Commitment of any Lender over the amount thereof then in effect without
         the consent of such Lender, or waive or amend any scheduled reduction
         in such Commitment (it being understood that amendments or waivers of
         conditions precedent, covenants, Defaults or Events of Default shall
         otherwise not constitute an increase in the Commitment of any Lender,
         and that an increase in the available portion of any Commitment of any
         Lender shall not constitute an increase in the Commitment of such
         Lender);

                  (iii) the consent of the Agent, the Collateral Agent or the
         Issuing Bank, as the case may be, shall be required for any amendment,
         waiver or consent affecting the rights or duties of the Agent, the
         Collateral Agent or the Issuing Bank under any Credit Document, in
         addition to the consent of the Lenders otherwise required by this
         Section 10.11; and

                   (iv) the consent of the Borrowers shall not be required for
         any amendment, modification or waiver of the provisions of Article IX
         (other than Section 9.9).

                  (b) The Borrowers and the Lenders hereby authorize the Agent
to modify this Credit Agreement by unilaterally amending or supplementing
Schedule I to reflect assignments of the Commitments.

                  (c) Notwithstanding the foregoing, the Borrowers may amend
Schedule 6.1(a) and Schedule 6.1(k) without the consent of the Majority Lenders;
PROVIDED THAT, except as contemplated by Section 8.1, no amendment to any such
Schedule shall be permitted to cure any Default or Event of Default which would
otherwise have existed in the absence of such amendment; and PROVIDED FURTHER
THAT, with respect to any amendment to Schedule 6.1(k) the Borrower shall comply
with Section 7.1(c)(v).

                  (d) If, in connection with any proposed amendment or waiver
of any of the provisions of this Credit Agreement as contemplated by Section
10.11(a)(i), the consent of the Majority Lenders is obtained but the consent of
one or more of such other Lenders whose consent is required is not obtained,
then the Borrowers shall have the right to replace each such nonconsenting
Lender or Lenders (so long as all non-consenting Lenders are so replaced) with
one or more replacement Lenders pursuant to Section 4.11 so long as at the time
of such replacement, each such replacement Lender consents to the proposed
amendment or waiver; provided that the Borrowers shall not have the right to
replace a Lender solely as a result of the exercise of such Lender's rights (and
the withholding of any required consent by such Lender) pursuant to Section
10.11(a)(i).

                  SECTION 10.12. NONLIABILITY OF AGENT, COLLATERAL AGENT,
CO-AGENTS AND LENDERS. The relationship between the Borrowers and the Lenders,
the Collateral Agent and the Agent shall be solely that of borrower and lender.
Neither the Agent, the Collateral Agent nor any Lender shall have any fiduciary
responsibilities to any Borrower. Neither the Agent nor any Lender undertakes
any responsibility to the Borrowers to review or inform the Borrowers of any
matter in connection with any phase of the Borrowers' business or operations.
None of the Co-Agents shall have any duties, obligations or liabilities
hereunder in its capacity as Co-Agent.

                  SECTION 10.13. INDEPENDENT NATURE OF LENDERS' RIGHTS. The
amounts payable at any time hereunder to each Lender under such Lender's
Revolving Note or Notes shall be a separate and independent debt.

                  SECTION 10.14. COUNTERPARTS. This Credit Agreement and any
waiver or amendment hereto may be executed in any number of counterparts and by
the different parties hereto in separate counterparts, each of which when so
executed and delivered shall be an original, but all of which shall together
constitute one and the same instrument.

                  SECTION 10.15. EFFECTIVENESS. This Credit Agreement shall
become effective on the date on which all of the parties hereto shall have
signed a copy hereof (whether the same or different copies) and shall have
delivered the same to the Agent, or, in the case of the Lenders, shall have
given to the Agent written, telecopied or telex notice (actually received) at
such office that the same has been signed and mailed to it.

                  SECTION 10.16. SEVERABILITY. In case any provision in or
obligation under this Credit Agreement or the Revolving Notes or the other
Credit Documents shall be invalid, illegal or unenforceable in any jurisdiction,
the validity, legality and enforceability of the remaining provisions or
obligations, or of such provision or obligation in any other jurisdiction, shall
not in any way be affected or impaired thereby.

                  SECTION 10.17. MAXIMUM RATE. Notwithstanding anything to the
contrary contained elsewhere in this Credit Agreement or in any other Credit
Document, the Borrowers, the Agent and the Lenders hereby agree that all
agreements among them under this Credit Agreement and the other Credit
Documents, whether now existing or hereafter arising and whether written or
oral, are expressly limited so that in no contingency or event whatsoever shall
the amount paid, or agreed to be paid, to the Agent or any Lender for the use,
forbearance, or detention of the money loaned to the Borrowers and evidenced
hereby or thereby or for the performance or payment of any covenant or
obligation contained herein or therein, exceed the Highest Lawful Rate. If due
to any circumstance whatsoever, fulfillment of any provisions of this Credit
Agreement or any of the other Credit Documents at the time performance of such
provision shall be due shall exceed the Highest Lawful Rate, then,
automatically, the obligation to be fulfilled shall be modified or reduced to
the extent necessary to limit such interest to the Highest Lawful Rate, and if
from any such circumstance any Lender should ever receive anything of value
deemed interest by applicable law which would exceed the Highest Lawful Rate,
such excessive interest shall be applied to the reduction of the principal
amount then outstanding hereunder or on account of any other then outstanding
Obligations and not to the payment of interest, or if such excessive interest
exceeds the principal unpaid balance then outstanding hereunder and such other
then outstanding Obligations, such excess shall be refunded to the Borrowers.
All sums paid or agreed to be paid to the Agent or any Lender for the use,
forbearance, or detention of the Obligations and other indebtedness of the
Borrowers to the Agent or any Lender shall, to the extent permitted by
applicable law, be amortized, prorated, allocated and spread throughout the full
term of such indebtedness, until payment in full thereof, so that the actual
rate of interest on account of all such indebtedness does not exceed the Highest
Lawful Rate throughout the entire term of such indebtedness. The terms and
provisions of this Section shall control every other provision of this Credit

                                      -117-

Agreement and all agreements among the Borrowers, the Agent and the Lenders.

                  SECTION 10.18. ENTIRE AGREEMENT; SUCCESSORS AND ASSIGNS. This
Credit Agreement and the other Credit Documents constitute the entire agreement
among the Borrowers, the Agent and the Lenders, supersedes any prior agreements
among them, and shall bind and benefit the Borrowers and the Lenders and their
respective successors and permitted assigns.

                  SECTION 10.19. JUDGMENT. The obligation of Wang Canada in
respect of any sum due from it to the Agent, the Collateral Agent or any Lender
under any Credit Document shall, notwithstanding any judgment in a currency
other than Dollars, be discharged only to the extent that on the Business Day
following receipt by the Agent, the Collateral Agent or such Lender of any sum
adjudged to be so due in such other currency, the Agent, the Collateral Agent or
such Lender may in accordance with normal banking procedures purchase Dollars
with such other currency; if the Dollars so purchased are less than the sum
originally due to the Agent, the Collateral Agent or such Lender in Dollars, the
Borrowers agree, as a separate obligation and notwithstanding any such judgment,
to, jointly and severally, indemnify the Agent, the Collateral Agent or such
Lender against such loss, and if the Dollars so purchased exceed the sum
originally due to the Agent, the Collateral Agent or such Lender in Dollars, the
Agent, the Collateral Agent or such Lender agrees to remit to Wang Canada such
excess.

                  SECTION 10.20. WAIVER OF IMMUNITIES. To the extent that Wang
Canada has or hereafter may acquire any immunity from jurisdiction of any court
or from any legal process (whether through service or notice, attachment prior
to judgment, attachment in aid of execution, execution or otherwise) with
respect to itself or its property, to the fullest extent permitted by law, Wang
Canada hereby irrevocably waives such immunity in respect of its obligations
under this Credit Agreement and any other Credit Document to which it is a party
and, without limiting the generality of the foregoing, agrees that the waivers
set forth in this Section shall have the fullest scope permitted under the
Foreign Sovereign Immunities Act of 1976 of the United States and are intended
to be irrevocable for purposes of such Act.

                  SECTION 10.21. INTEREST ACT (CANADA). Wang Canada hereby
acknowledges that the rate or rates of interest applicable to the Obligations
are computed on the basis of a year of 360 days and paid for the actual number
of days elapsed. For purposes of the Interest Act (Canada), at any time and from
time to time, the yearly rate of interest provided in this Credit Agreement,
which is paid or payable by the Borrowers pursuant hereto is equivalent and may
be determined by multiplying the

                                      -118-


<PAGE>   125




applicable rate of interest by the number of days in such calendar year and
dividing such product by 360.

                  IN WITNESS WHEREOF, the parties hereto have caused this Credit
Agreement to be executed by their proper and duly authorized officers as of the
date set forth above.

                                                                  EXECUTION COPY

     AGREEMENT made this 20th day of August, 1996 by and among Wang
Laboratories, Inc. ("Wang"), Wang Federal, Inc. ("WFI"), BT Commercial
Corporation, as Agent (the "Agent"), and Heller Financial, Inc. ("Heller").

     Reference is made to the Credit Agreement dated as of January 30, 1995 (as
amended, supplemented or otherwise modified from time to time, the "CREDIT
AGREEMENT"; capitalized terms used herein shall have the meanings given such
terms in the Credit Agreement unless otherwise defined herein), among Wang and
WFI as Borrowers, the financial institutions from time to time parties thereto,
as Lenders, the Agent, Fleet National Bank of Massachusetts and BayBank, as
Co-Agents, and Bankers Trust Company, as Issuing Bank.

     The Agent and Wang have informed Heller that they intend to amend and
restate the Credit Agreement and provide for, among other things, an increase
in the aggregate Commitments. Heller is unwilling to agree to such amendment and
restatement or to an increase in the aggregate Commitments unless its Commitment
is terminated and it is paid all amounts due it under the terms of the Credit
Agreement. Accordingly, the Agent, Wang, WFI and Heller hereby agree as follows:

     1. In accordance with Section 10.11 of the Credit Agreement, Heller hereby
agrees to the amendment and restatement of the Credit Agreement.


     2. Upon the closing of the amendment and restatement of the Credit
Agreement (the "Closing") and the satisfaction of the conditions set forth in
paragraph 3 below, Heller shall no longer have any rights under the Credit
Agreement and the other Credit Documents, shall be released from its obligations
under the Credit Agreement and the other Credit Documents and its Commitment
shall be terminated.

     3. The terms of this Agreement shall be effective only upon the
satisfaction of each of the following conditions:

     a.   Receipt by the Agent by telecopy of a copy of this Agreement executed
          by all of the parties hereto;

     b.   Receipt by the Agent of the originally executed Revolving Note held by
          Heller; and

     c.   Receipt by Heller by wire transfer of an amount which represents
          Heller's share of the Obligations outstanding as of the date of the
          Closing.

     4. Heller represents and warrants that it is the legal and beneficial owner
of the interest being released by it hereunder and that such interest is free
and clear of any adverse claims.

     5. This Agreement may be executed in any number of counterparts and by the
different parties hereto in separate counterparts, each of which when so
executed and delivered shall be an original, but all of which shall together
constitute one and the same instrument.

     6. The validity, interpretation and enforcement of this Agreement shall be
governed by the laws of the state of New York without giving effect to the
conflict of laws principles (other than Section 5-1401 of the New York General
Obligations Law).

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed by their respective duly authorized officers as of the first date above
written.
