          WHEREAS, upon completion of the Macro Acquisition, Company will be a

          (B)  Revolving Loans.  (1) Each Lender agrees, severally and not
               ---------------
jointly, to lend to Borrowers  from the Closing Date to the Expiry Date its Pro
Rata Share of the loans requested by Parent, on behalf of Borrowers, to be made
by Lenders under this subsection 1.1(B), up to an aggregate maximum for all
Lenders of $20,000,000 (as the same may be reduced from time to time hereunder,
the "Revolving Loan Commitment").  Advances or amounts outstanding under the
Revolving Loan Commitment will be called "Revolving Loans".  Revolving Loans may
be repaid and reborrowed.  The Revolving Loans shall be repaid in full on the
Expiry Date.   The "Maximum Revolving Loan Balance" will be the lesser of (a)
the "Borrowing Base" (as calculated on Exhibit 4.8(E), the "Borrowing Base
Certificate") less the sum of (i) outstanding Risk Participation Liability, plus
              ----                                                          ----
(ii) the Earn-Out Reserve, plus (iii) until the earlier to occur of final
                           ----
payment of the Macro Earn-Out and ProTel Earn-Out and the date on which it is
determined that no further obligation exists in respect of the Macro Earn-Out
and ProTel Earn-Out, $1,000,000 (the amount computed pursuant to this clause (a)
is referred to herein as "Borrowing Base Availability") or (b) the Revolving
Loan Commitment less the sum of (i) outstanding Risk Participation Liability,
                ----
plus (ii) the Earn-Out Reserve, plus (iii) until the earlier to occur of final
----                            ----
payment of the Macro Earn-Out and ProTel Earn-Out and the date on which it is
determined that no further obligation exists in respect of the Macro Earn-Out
and ProTel Earn-Out,  $1,000,000.  If at any time the outstanding Revolving
Loans exceed the Maximum Revolving Loan Balance (as it may be deemed increased
from time to time pursuant to subsection 1.1(B)(2)), Lenders shall not be
obligated to make Revolving Loans and issue Lender Letters of Credit and Risk
Participation Agreements, and Revolving Loans must be repaid immediately in an
amount sufficient to eliminate any excess.  Revolving Loans may be requested in
any amount with one (1) Business Day prior notice required for amounts equal to
or greater than $5,000,000.  For amounts less than $5,000,000, written or
telephonic notice must be provided by noon Chicago time on the day on which the
Loan is to be made.  All LIBOR Loans require three (3) Business Day's notice.
All Loans requested telephonically must be confirmed in writing within one (1)
Business Day.  Neither Agent nor any Lender shall incur any liability to
Borrowers for acting upon any telephonic notice that Agent believes in good
faith to have been given by a duly authorized officer or other person authorized
to borrow on behalf of Borrowers.

               (2)  If Parent requests that Lenders make, or permit to remain
outstanding, Revolving Loans in an aggregate amount in excess of Borrowing Base
Availability, Lenders having

                                       3
<PAGE>

sixty-six and two-thirds percent (66-2/3%) or more of the Revolving Loan
Commitment may in their discretion elect to cause all Lenders having a Revolving
Loan Commitment to make, or permit to remain outstanding, such excess Revolving
Loans (such Revolving Loans in excess of Borrowing Base Availability being
referred to as "Overadvance Revolving Loans"), provided, however, that such
                                               --------  -------
Lenders may not cause all Lenders having a Revolving Loan Commitment to make, or
permit to remain outstanding, (a) Revolving Loans in excess of the Revolving
Loan Commitment less outstanding Risk Participation Liability or (b) Overadvance
Revolving Loans in excess of $2,000,000. If Overadvance Revolving Loans are
made, or permitted to remain outstanding, pursuant to the preceding sentence,
then (a) the Maximum Revolving Loan Balance shall be deemed increased by the
amount of such permitted Overadvance Revolving Loans, but only for so long as
Lenders having sixty-six and two-thirds percent (66-2/3%) or more of the
Revolving Loan Commitment allow such Overadvance Revolving Loans to be
outstanding and for five (5) Business Days after notice by Agent to Parent that
such Lenders have terminated such allowance and (b) all Lenders that have
committed to make Revolving Loans shall be bound to make, or permit to remain
outstanding, such Overadvance Revolving Loans based upon their Pro Rata Shares
in accordance with the terms of this Agreement. Notwithstanding the foregoing,
if Overadvance Revolving Loans remain outstanding for more than ninety (90) days
during any 180-day period, Revolving Loans must be repaid immediately in an
amount sufficient to eliminate all of such Overadvance Revolving Loans.

               (3)  Borrowers shall have the right to permanently reduce the
Revolving Loan Commitment on not less than five (5) Business Days prior written
notice to Agent and Lenders provided (a) each reduction shall be in a minimum
amount of $1,000,000 and integral multiples of $500,000 in excess thereof, (b)
after giving effect to any such reduction, the Maximum Revolving Loan Balance
exceeds outstanding Revolving Loans by not less than $2,000,000 and (c) no more
than 3 reductions shall be permitted.

          (C)  Letters of Credit and Risk Participation Agreements.  The
               ---------------------------------------------------
Revolving Loan Commitment may, in addition to advances under the Revolving Loan,
be utilized, upon the request of Parent, on behalf of Borrowers, for (i) the
issuance of standby letters of credit for the account of a Borrower or its
Subsidiaries by Agent (each such letter of credit, a "Lender Letter of Credit")
or (ii) the issuance by Agent of risk participation agreements (each such
agreement, a "Risk Participation Agreement") to confirm payment to banks which
issue letters of credit for the account of a Borrower or its Subsidiaries.

               (1)  Maximum Amount.  The aggregate amount of Risk Participation
                    --------------
Liability with respect to all Lender Letters of Credit and Risk Participation
Agreements outstanding for the account of Borrowers at any time shall not exceed
$1,000,000.

               (2)  Reimbursement.  Borrowers shall be irrevocably and
                    -------------
unconditionally obligated forthwith without presentment, demand, protest or
other formalities of any kind, to reimburse Agent for any amounts paid by Agent
with respect to a Lender Letter of Credit or a Risk Participation Agreement
issued for the account of Borrowers, including all fees, costs and expenses paid
by Agent to any bank that issues letters of credit. Borrowers hereby authorize
and direct Agent, at Agent's option, to make a Revolving Loan in the amount of
any payment made by Agent with

                                       4
<PAGE>

respect to any Lender Letter of Credit or any Risk Participation Agreement. All
amounts paid by Agent with respect to any Lender Letter of Credit or Risk
Participation Agreement that are not immediately repaid by Borrowers with the
proceeds of a Revolving Loan or otherwise shall bear interest at the interest
rate applicable to Revolving Loans calculated using the Base Rate. Each Lender
agrees to fund its Pro Rata Share of any Revolving Loan made pursuant to this
subsection 1.1(C)(2). If no such Revolving Loan is made, each Lender agrees to
purchase, and shall be deemed to have purchased, a participation in such Lender
Letter of Credit or Risk Participation Agreement, as the case may be, in an
amount equal to its Pro Rata Share of the Risk Participation Liability of such
Lender Letter of Credit or Risk Participation Agreement, as the case may be, and
each Lender agrees to pay to Agent such Lender's Pro Rata Share of any payments
made by Agent under such Lender Letter of Credit and Risk Participation
Agreement. The obligation of each Lender to deliver to Agent an amount equal to
its respective Pro Rata Share pursuant to the preceding two (2) sentences shall
be absolute and unconditional and such remittance shall be made notwithstanding
the occurrence or continuation of an Event of Default or Default or the failure
to satisfy any condition set forth in subsection 7.2. If any Lender fails to
make available to Agent the amount of such Lender's Pro Rata Share of any
payments made by Agent in respect of such Lender Letter of Credit or Risk
Participation Agreement as provided in this subsection 1.1(C)(2), Agent shall be
entitled to recover such amount on demand from such Lender together with
interest at the Base Rate.

               (3)  Conditions of Issuance of Letters of Credit or Risk
                    ---------------------------------------------------
Participation Agreements. In addition to all other terms and conditions set
------------------------
forth in this Agreement, the issuance by Agent of any Lender Letter of Credit or
Risk Participation Agreement shall be subject to the conditions precedent that
the Lender Letter of Credit, the Risk Participation Agreement or the letter of
credit for which Parent requests a Risk Participation Agreement shall support a
transaction entered into in the ordinary course of Borrowers' business and shall
be in such form, be for such amount, and contain such terms and conditions as
are reasonably satisfactory to Agent. The expiration date of each Lender Letter
of Credit and each letter of credit to be issued under a Risk Participation
Agreement shall be on a date which is the earlier of (a) one year from its date
of issuance, or (b) the thirtieth (30th) day before the date set forth in clause
(c) of the definition of the term Expiry Date. Each Risk Participation Agreement
shall provide that the agreement terminates and all demand or claims for payment
must be presented by a date certain, which date will be at least thirty (30)
days before the date set forth in clause (c) of the definition of the term
Expiry Date.

               (4)  Request for Lender Letters of Credit or Risk Participation
                    ----------------------------------------------------------
Agreements.  Parent shall give Agent at least three (3) Business Days prior
----------
notice specifying the date a Lender Letter of Credit is requested to be issued,
identifying the beneficiary and describing the nature of the transactions
proposed to be supported thereby.  Upon Parent's request, Agent shall use
reasonable efforts to arrange Risk Participation Agreements. After the issuance
of a Risk Participation Agreement in favor of a bank that will issue letters of
credit on behalf of a Borrower or one of its Subsidiaries, Parent shall give
Agent at least two (2) Business Days prior written notice specifying the date a
letter of credit is to be issued under a Risk Participation Agreement,
identifying the beneficiary and describing the nature of the transactions
proposed to be supported thereby.  Any notice described in this paragraph shall
be accompanied by the form of the Lender Letter of Credit or the letter of
credit to which such Risk Participation Agreement relates.

                                       5
<PAGE>

          (D)  Notes.  Each Borrower shall execute and deliver to each Lender
               -----
(i) a Note to evidence the Revolving Loans, such Note to be in the principal
amount of such Lender's Pro Rata Share of the Revolving Loan Commitment and (ii)
a Note to evidence the Term Loan, such Note to be in the principal amount of
such Lender's Pro Rata Share of the Term Loan. In the event of an assignment
under subsection 8.1, Borrowers shall, upon surrender of the assigning Lender's
Notes, issue new Notes to reflect the interests of the assigning Lender and the
Person to which interests are to be assigned.

          (E)  Funding Authorization.  The proceeds of all Loans made pursuant
               ---------------------
to this Agreement subsequent to the Closing Date are to be funded by wire
transfer to the following account of Parent:

          Bank:               The Chase Manhattan Bank
          ABA No.:            021000021
          Bank Address:       36 E. Midland, Paramus, NJ 07562
          Account No.:        777370093
          Reference:          Opinion Research Corporation

Parent shall provide Agent with written notice of any change in the foregoing
instructions at least three (3) Business Days before the desired effective date
of such change.

          (F)  Parent as Agent.  (1) The Borrowers maintain an integrated cash
               ---------------
management system reflecting their interdependence on one another and the mutual
benefits shared among them as a result of their respective operations.  In order
to efficiently fund and operate their respective businesses and minimize the
number of borrowings which they will make under this Agreement and thereby
reduce the administrative costs and record keeping required in connection
therewith, including the necessity to enter into and maintain separately
identified and monitored borrowing facilities, the Borrowers have requested, and
the Agent and the Lenders have agreed that, subject to subsection 9.19, (i) all
Loans will be advanced to and for the account of the Borrowers on a joint and
several basis to the account identified in subsection 1.1(E) and (ii) all
Letters of Credit and Risk Participation Agreements will be issued pursuant to
requests executed by Parent on behalf of and for the account of Borrowers.  Each
Borrower hereby acknowledges that it will be receiving a direct benefit from
each Loan made and each Letter of Credit issued pursuant to this Agreement.

          (2)  Each Borrower hereby designates, appoints, authorizes and
empowers Parent as its agent to act as specified in subsections 1.1 and 1.2 of
this Agreement and each of the other Loan Documents and Parent hereby
acknowledges such designation, authorization and empowerment, and accepts such
appointment. Each Borrower hereby irrevocably authorizes and directs Parent to
take such action on its behalf under the respective provisions of this Agreement
and the other Loan Documents, and any other instruments, documents and
agreements referred to herein or therein, and to exercise such powers and to
perform such duties hereunder and thereunder as are specifically delegated to or
required of the Parent by the respective terms and provisions hereof and

                                       6
<PAGE>

thereof, and such other powers as are reasonably incidental thereto, including,
without limitation, to take the following actions for and on such Borrower's
behalf:

               (i)    to submit on behalf of each Borrower notices of borrowing
     (and LIBOR Loan Requests) to Agent in accordance with the provisions of
     this Agreement; and

               (ii)   to receive on behalf of each Borrower the proceeds of the
     Loans in accordance with the provisions of this Agreement, such proceeds to
     be disbursed to or for the account of the applicable Borrower as soon as
     practicable after its receipt thereof;

               (iii)  to submit on behalf of each Borrower requests for the
     issuance of Letters of Credit and Risk Participation Agreements in
     accordance with the provisions of this Agreement, each such requests for
     the issuance of a Letter of Credit to be submitted by Parent as soon as
     practicable after its receipt o a request to do so from any Borrower; and

               (iv)   to submit on behalf of each Borrower, Borrowing Base
     Certificates, Compliance Certificates, Excess Cash Flow Certificates, and
     all other certificates, notices and other communications given or required
     to be given, hereunder.

Parent is further authorized and directed by each of the Borrowers to take all
such actions on behalf of such Borrower necessary to exercise the specific power
granted in clauses (i) through (iv) above and to perform such other duties
hereunder and under the other Loan Documents, and deliver such documents as
delegated to or required of Parent by the terms hereof or thereof.

          (3)  The administration by Agent and Lenders of the respective credit
facilities under this Agreement as a co-borrowing facility with a borrowing
agent in the manner set forth herein is solely as an accommodation to Borrowers
and at their request and neither Agent nor any Lender shall incur any liability
to any of the Borrowers as a result thereof.

          1.2  Interest and Related Fees.
               -------------------------

          (A)  Interest.  From the date the Loans are made and the date the
               --------
other Obligations become due, depending upon Parent's election from time to
time, as permitted herein, to have portions of the Loans accrue interest
determined by reference to the Base Rate ("Base Rate Loans") or the LIBOR
("LIBOR Loans"), the Loans and the other Obligations shall bear interest at the
applicable rates set forth below:

          (1)  If a LIBOR Loan, then at the sum of the LIBOR plus the LIBOR
                                                             ----
Margin.

          (2)  In all other cases, then at the sum of the Base Rate plus the
                                                                    ----
               Base Rate Margin.

          "Base Rate" means a variable rate of interest per annum equal to the
rate of interest from time to time published by the Board of Governors of the
Federal Reserve System in Federal Reserve statistical release H.15 (519)
entitled "Selected Interest Rates" as the Bank prime loan rate.  Base Rate also
includes rates published in any successor publications of the Federal Reserve
System

                                       7
<PAGE>

reporting the Bank prime loan rate or its equivalent. The statistical release
generally sets forth a Bank prime loan rate for each business day. The
applicable Bank prime loan rate for any date not set forth shall be the rate set
forth for the last preceding date. In the event the Board of Governors of the
Federal Reserve System ceases to publish a Bank prime loan rate or equivalent,
the term "Base Rate" shall mean a variable rate of interest per annum equal to
the highest of the "prime rate," "reference rate," "base rate" or other similar
rate as determined by Agent announced from time to time by any of Bankers Trust
Company, The Chase Manhattan Bank or Citibank, N.A. (with the understanding that
any such rate may merely be a reference rate and may not necessarily represent
the lowest or best rate actually charged to any customer by such bank).

          "Base Rate Margin" shall mean (i) as of the Closing Date, 1.25% per
annum, and (ii) thereafter, as of April 1, July 1, October 1 and January 1 of
each year (each, an "Adjustment Date"), commencing on January 1, 2000, the Base
Rate Margin shall be adjusted, if necessary, to the applicable percent per annum
set forth in the pricing table below opposite the Total Adjusted Indebtedness to
Adjusted EBITDA Ratio calculated for the trailing twelve month period ending on
the last day of the most recently completed calendar quarter prior to the
applicable Adjustment Date (each such period, a "Calculation Period").

          "LIBOR" means, for each Interest Period, a rate  equal to:  (a) the
offered rate for deposits in U.S. dollars in the London interbank market for the
relevant Interest Period which is published by the British Bankers' Association
and currently appears on Telerate Page 3750 as of 11:00 a.m. (London time) on
the day which is two (2) Business Days prior to the first day of such Interest
Period for a term comparable to such Interest Period; provided, however, that
                                                      --------  -------
if, for any reason, such a rate is not published by the British Bankers'
Association on Telerate or any other source available to Agent, LIBOR shall be
equal to a rate per annum equal to the average rate (rounded upwards, if
necessary, to the nearest 1/100 of 1%) at which Agent determines that U.S.
dollars in an amount comparable to the amount of the applicable Loans are being
offered to prime banks at approximately 11:00 a.m. (London time) on the day
which is two (2) Business Days prior to the first day of such Interest Period

available funds by leading banks in the London interbank market selected by
Agent; divided by (b) a number equal to 1.0 minus the aggregate (but without

balance of the Revolving Loans for the one month period ending on the last day
of the month for which the Compliance Certificate most recently delivered
pursuant to subsection 4.8(C) was prepared, plus (b) the outstanding principal

          If Borrowers shall fail to deliver a Compliance Certificate by the
date required pursuant to subsection 4.8(C), effective as of the tenth Business
Day following the date on which such Compliance Certificate was due, each
applicable Base Rate Margin and each applicable LIBOR Margin shall be
conclusively presumed to equal the highest applicable Base Rate Margin and the
highest applicable LIBOR Margin specified in the pricing table set forth above
until the date of delivery of the Compliance Certificate.

          Each LIBOR Loan may be obtained for a one, two, three or six month
period (each being an "Interest Period").  With respect to all LIBOR Loans:  (a)
the Interest Period will commence on the date that the LIBOR Loan is made or the
date on which a Base Rate Loan is converted into a LIBOR Loan, as applicable, or
in the case of immediately successive Interest Periods, each successive Interest
Period shall commence on the day on which the next preceding Interest Period
expires, (b) if the Interest Period expires on a day that is not a Business Day,
then it will expire on the next Business Day, (c) no Interest Period for
Revolving Loans shall extend beyond the date set forth in clause (c) of the
definition of the term "Expiry Date" and (d) no Interest Period for any portion
of the Term Loan shall extend beyond the date of the final Scheduled Installment
thereof.

<PAGE>

          If the introduction of or the interpretation of (in each case, made
after the date hereof) any law, rule, or regulation would increase the reserve
requirement or otherwise increase the cost to any Lender of making or
maintaining a LIBOR Loan, then Agent, on behalf of all affected Lenders, shall
submit a certificate to Borrowers demonstrating the calculation of the increased
cost and requiring payment thereof to Agent for the benefit of the affected
Lenders within ten days after the date of the certificate.  There are no
limitations on the number of times such certificate may be submitted.

          (B)  Commitment Fee. From the Closing Date, Borrowers shall pay Agent,
               --------------
for the benefit of all Lenders committed to make Revolving Loans (based upon
their respective Pro Rata Shares), a fee in an amount equal to (1) (a) the
Revolving Loan Commitment less (b) the sum of (i) the average daily balance of
                          ----
the Revolving Loans plus (ii) the average daily aggregate amount of outstanding
                    ----
Risk Participation Liability, in each case during the preceding month,
multiplied by (2) one-half of one percent (0.50%) per annum.  Such fee is to be
---------- --
paid monthly in arrears on the first day of each month.

          (C)  Risk Participation Fee.  From the Closing Date, Borrowers shall
               ----------------------
pay Agent, for the benefit of all Lenders committed to make Revolving Loans
(based upon their respective Pro Rata Shares), a fee for each Lender Letter of
Credit and each Risk Participation Agreement from the date of issuance to the
date of termination equal to the average daily aggregate amount of outstanding
Risk Participation Liability multiplied by a percent per annum equal to the
                             ---------- --
LIBOR Margin in effect on the date such fee is due and payable.  Such fee is to
be paid monthly in arrears on the first day of each month.  Borrowers shall also
reimburse Agent for any and all fees and expenses paid by Agent to the issuer of
any letter of credit that is supported by a Risk Participation Agreement.

          (D)  Computation of Interest and Related Fees.  Interest on all Loans
               ----------------------------------------
and all other Obligations and any fees set forth in this subsection 1.2 shall be
calculated daily on the basis of a three hundred sixty (360) day year for the
actual number of days elapsed in the period during which it accrues. The date of
funding a Base Rate Loan and the first day of an Interest Period with respect to
a LIBOR Loan shall be included in the calculation of interest. The date of
payment of a Base Rate Loan and the last day of an Interest Period with respect
to a LIBOR Loan shall be excluded from the calculation of interest. If a Loan is
repaid on the same day that it is made, one (1) days' interest shall be charged.
Interest on all Base Rate Loans is payable in arrears on the first day of each
month and on the maturity of such Loans, whether by acceleration or otherwise.
Interest on LIBOR Loans shall be payable on the last day of the applicable
Interest Period, unless the Interest Period is greater than three (3) months, in
which case interest will be payable on the last day of each three (3) month
interval. In addition, interest on LIBOR Loans is due on the maturity of such
Loans, whether by acceleration or otherwise.

          (E)  Default Rate of Interest.  At the election of Agent or Requisite
               ------------------------
Lenders, after the occurrence of an Event of Default and for so long as it
continues, the Loans and other Obligations shall bear interest at a rate that is
two percent (2.0%) in excess of the rates otherwise payable under this
Agreement. Furthermore, during any period in which any Event of Default is
continuing, as the Interest Periods for LIBOR Loans then in effect expire, such
Loans shall be converted at Agent's

                                       10
<PAGE>

discretion into Base Rate Loans and the LIBOR election will not be available to
Borrowers until all Events of Default are cured or waived.

          (F)  Excess Interest.  Under no circumstances will the rate of
               ---------------
interest chargeable be in excess of the maximum amount permitted by law. If
excess interest is charged and paid in error, then the excess amount will be
promptly refunded.

          (G)  LIBOR Rate Election.  All Loans made on the Closing Date shall be
               -------------------
Base Rate Loans and remain so until the earlier of ten (10) days after the
Closing Date or completion of the primary syndication of the credit facilities.
If the primary syndication of the credit facilities is not complete by the tenth
day after the Closing Date, then Parent, on behalf of Borrowers, may not select
an Interest Period for a LIBOR Loan which is longer than one month prior to the
earlier of ninety (90) days after the Closing Date or the date Agent notifies
Borrowers, that it has completed such primary syndication. Thereafter, Parent,
on behalf of Borrowers may request that Revolving Loans to be made be LIBOR
Loans, that outstanding portions of Revolving Loans and the Term Loan be
converted to LIBOR Loans and that all or any portion of a LIBOR Loan be
continued as a LIBOR Loan upon expiration of the applicable Interest Period. Any
such request will be made by Parent submitting a LIBOR Loan request in the form
of Exhibit 1.2(G). Once given, a LIBOR Loan request shall be irrevocable and
Borrowers shall be bound thereby. Upon the expiration of an Interest Period, in
the absence of a new LIBOR Loan request submitted to Agent not less than three
(3) Business Days prior to the end of such Interest Period, the LIBOR Loan then
maturing shall be automatically converted to a Base Rate Loan. There may be no
more than six (6) LIBOR Loans outstanding at any one time. Loans which are not
the subject of a LIBOR Loan request shall be Base Rate Loans. Agent will notify
Lenders, by telephonic or facsimile notice, of each LIBOR Loan request received
by Agent not less than two (2) Business Days prior to the first day of the
Interest Period of the LIBOR Loan requested thereby.

          1.3  Other Fees and Expenses.
               -----------------------

          (A)  Certain Fees.  Borrowers shall pay to Heller, individually, the
               ------------
fees in the amounts and at the times specified in that certain letter agreement
dated the date of this Agreement among Borrowers and Heller.

          (B)  LIBOR Breakage Fee.  Upon (i) any default by Borrowers in making
               ------------------
any borrowing of, conversion into or continuation of any LIBOR Loan following
delivery to Agent of any LIBOR Loan request in respect thereof or (ii) any
payment of a LIBOR Loan on any day that is not the last day of the Interest
Period applicable thereto (regardless of the source of such prepayment and
whether voluntary, by acceleration or otherwise), Borrowers shall pay Agent, for
the benefit of all Lenders, an amount (the "LIBOR Breakage Fee") equal to the
amount of any losses, expenses and liabilities (including, without limitation,
any loss (including interest paid) in connection with the re-employment of such
funds) that any Lender may sustain as a result of such default or such payment.
For purposes of calculating amounts payable to a Lender under this subsection,
each Lender shall be deemed to have actually funded its relevant LIBOR Loan
through the purchase of a deposit bearing interest at the LIBOR Rate in an
amount equal to the amount of that LIBOR Loan

                                       11
<PAGE>

and having a maturity and repricing characteristics comparable to the relevant
Interest Period; provided, however, that each Lender may fund each of its LIBOR
Loans in any manner it sees fit, and the foregoing assumption shall be utilized
only for the calculation of amounts payable under this subsection.

          (C)  Expenses and Attorneys Fees.  Borrowers agree to promptly pay all
               ---------------------------
reasonable out-of-pocket fees, costs and expenses (including those of attorneys)
incurred by Agent in connection with any matters contemplated by or arising out
of the Loan Documents, in connection with the examination, review, due diligence
investigation, documentation, negotiation, closing and syndication of the
transactions contemplated herein and in connection with the continued
administration of the Loan Documents including any amendments, modifications and
waivers.  Borrowers agree to promptly pay all fees, costs and expenses incurred
by Agent and Lenders in connection with any action to enforce any Loan Document
or to collect any payments due from Borrowers or any other Loan Party.  All
fees, costs and expenses for which a Borrower is responsible under this
subsection 1.3(C) shall be deemed part of the Obligations when incurred, payable
in accordance with the final two sentences of subsection 1.4 and secured by the
Collateral.

          1.4  Payments.  All payments by Borrowers of the Obligations shall
               --------
be made in same day funds and delivered to Agent, for the benefit of Agent and
Lenders, as applicable, by wire transfer to the following account or such other
place as Agent may from time to time designate.

                         ABA No. 0710-0001-3

Borrowers shall receive credit on the day of receipt for funds received by Agent
by 1:00 p.m. Chicago time. In the absence of timely receipt, such funds shall be
deemed to have been paid on the next Business Day. Whenever any payment to be
made hereunder shall be stated to be due on a day that is not a Business Day,
the payment may be made on the next succeeding Business Day and such extension
of time shall be included in the computation of the amount of interest and fees
due hereunder.

          Each Borrower hereby authorizes Lenders to make Revolving Loans, on
the basis of their Pro Rata Shares, for the payment of Scheduled Installments,
interest, commitment fees, Risk Participation Liability fees, LIBOR Breakage
Fees and Risk Participation Liability payments. Prior to an Event of Default,
other fees, costs and expenses (including those of attorneys) reimbursable to
Agent pursuant to subsections 1.3(A) and (C) or elsewhere in any Loan Document
may be debited to the Revolving Loan after fifteen (15) days notice. After the
occurrence of an Event of Default, no notice will be required.

                                       12

          1.5  Prepayments.
               -----------

          (A)  Voluntary Prepayment of Term Loan.  At any time, Borrowers may
               ---------------------------------
prepay the Term Loan, in whole or in part, but with LIBOR Breakage Fees, if
applicable. The payments shall be applied in accordance with subsection 1.5(E)
or as otherwise may be agreed by Requisite Lenders.

          (B)  Prepayments from Excess Cash Flow.  Within one hundred (100) days
               ---------------------------------
after the end of each of its fiscal years, Borrowers shall prepay the Loans in
an amount equal to fifty percent (50%) of the Excess Cash Flow for such fiscal
year determined pursuant to the calculation on Exhibit 1.5(B). The calculation
shall be based on the audited financial statements for Parent and its
Subsidiaries. The payments shall be applied in accordance with subsection
1.5(E).

          (C)  Prepayments from Asset Dispositions.  Immediately upon receipt of
               -----------------------------------
the Net Proceeds in excess of $250,000 for any single transaction or series of
transactions, Borrowers shall repay the outstanding principal balance of the
Revolving Loan by the amount of any reduction in the Borrowing Base attributable
to the Asset Disposition giving rise to such Net Proceeds. Parent or any
Subsidiary may reinvest all remaining Net Proceeds of such Asset Disposition
(including insurance proceeds payable on account of a casualty), within one
hundred eighty (180) days, in productive replacement fixed assets of a kind then
used or usable in the business of Parent and its Subsidiaries. If Borrowers do
not intend to so reinvest such Net Proceeds or if the period set forth in the
immediately preceding sentence expires without Parent or its Subsidiaries having
reinvested such Net Proceeds, Borrowers shall prepay the Term Loan in an amount
equal to the remaining Net Proceeds of such Asset Disposition. The payments
shall be applied in accordance with subsection 1.5(E).

          (D)  Prepayment from Issuance of Securities.  Immediately upon the
               --------------------------------------
receipt by  Parent or any of its Subsidiaries of the proceeds of the issuance of
equity securities (other than (1) proceeds of the issuance of equity securities
received on or before the Closing Date, (2) proceeds from the issuance of equity
securities to members of the management of Parent and (3) proceeds of the
issuance of equity securities to Parent or any Subsidiary of Parent), Borrowers
shall prepay the Loans in an amount equal to such proceeds, net of underwriting
discounts and commissions and other reasonable costs associated therewith.  The
payments shall be applied in accordance with subsection 1.5(E).

          (E)  Application of Proceeds.  With respect to the prepayments
               -----------------------
described in subsections 1.5(A), 1.5(B), 1.5(C) (other than any amount applied
to the Revolving Loans as a result of the reduction of the Borrowing Base as
specified therein) and 1.5(D), such prepayments shall first be applied in
payment of the Term Loan pro rata against all remaining Scheduled Installments
and, at any time after the Term Loan shall have been prepaid in full, such
prepayments shall be applied to reduce the outstanding principal balance of the
Revolving Loans.  Considering each type of Loan being prepaid separately, in the
absence of an Event of Default, any such prepayment shall be applied first to
Base Rate Loans of the type required to be prepaid before application to LIBOR
Loans of the

                                       13
<PAGE>

type required to be prepaid, in each case in a manner which minimizes the amount
of any payment required to be made by Borrowers pursuant to subsection 1.3(B).

          1.6  Maturity.  All of the Obligations shall become due and payable
               --------
as otherwise set forth herein, but in any event, all of the remaining
Obligations shall become due and payable on the date set forth in clause (c) of
the definition of the term "Expiry Date."  Until all Obligations have been fully
paid and satisfied, the Revolving Loan Commitment has been terminated and all
Lender Letters of Credit and Risk Participation Agreements have been terminated,
Agent, for the benefit of Agent and Lenders, shall be entitled to retain the
security interests in the Collateral granted under the Security Documents and
the ability to exercise all rights and remedies available to them under the Loan
Documents and applicable laws.

          1.7  Loan Accounts.  Agent will maintain loan account records for
               -------------
(a) all Loans, interest charges and payments thereof, (b) all Risk Participation
Liability, (c) the charging and payment of all fees, costs and expenses and (d)
all other debits and credits pursuant to this Agreement.  The balance in the
loan accounts shall be presumptive evidence of the amounts due and owing to
Lenders, provided that any failure by Agent to so record shall not limit or
         --------
affect the Borrowers' obligation to pay.  Within five (5) days of the first of
each month, Agent shall provide a statement for each loan account setting forth
the principal of each account and interest due thereon.  Borrowers must deliver
a written objection within sixty (60) days after receipt of the statement or the
statement will be presumptive evidence of the Obligations absent manifest error.
During the continuance of an Event of Default, each Borrower irrevocably waives
the right to direct the application of any and all payments and each Borrower
hereby irrevocably agrees that Agent shall have the continuing exclusive right
to apply and reapply payments in any manner it deems appropriate.

          1.8  Capital Adequacy and Other Adjustments.  In the event that any
               --------------------------------------
Lender shall have determined that the adoption after the date hereof of any law,
treaty, governmental (or quasi-governmental) rule, regulation, guideline or
order regarding capital adequacy, reserve requirements or similar requirements
or compliance by any Lender or any corporation controlling such Lender with any
request or directive regarding capital adequacy, reserve requirements or similar
requirements (whether or not having the force of law and whether or not failure
to comply therewith would be unlawful) from any central bank or governmental
agency or body having jurisdiction does or shall have the effect of increasing
the amount of capital, reserves or other funds required to be maintained by such
Lender or any corporation controlling such Lender and thereby reducing the rate
of return on such Lender's or such corporation's capital as a consequence of its
obligations hereunder, then Borrowers shall from time to time within fifteen
(15) days after notice and demand from such Lender (together with the
certificate referred to in the next sentence and with a copy to Agent) pay to
Agent, for the account of such Lender, additional amounts sufficient to
compensate such Lender for such reduction.  A certificate as to the amount of
such cost and showing the basis of the computation of such cost submitted by
such Lender to Borrowers and Agent shall, absent demonstrable error, be final,
conclusive and binding for all purposes.

          1.9  Taxes.
               -----

                                       14
<PAGE>

          (A)  No Deductions.  Any and all payments or reimbursements made
               -------------
hereunder or under the Notes shall be made free and clear of and without
deduction for any and all taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto (all such taxes, levies,
imposts, deductions, charges or withholdings and all liabilities with respect
thereto excluding such taxes imposed on net income, herein "Tax Liabilities"),
excluding, however, taxes imposed on the net income of a Lender or Agent.  If
Borrowers shall be required by law to deduct any such amounts from or in respect
of any sum payable hereunder to any Lender or Agent, then the sum payable
hereunder shall be increased as may be necessary so that, after making all
required deductions, such Lender or Agent receives an amount equal to the sum it
would have received had no such deductions been made.

          (B)  Changes in Tax Laws. In the event that, subsequent to the Closing
               -------------------
Date, (1) any changes in any existing law, regulation, treaty or directive or in
the interpretation or application thereof, (2) any new law, regulation, treaty
or directive enacted or any interpretation or application thereof, or (3)
compliance by Agent or any Lender with any request or directive (whether or not
having the force of law) from any governmental authority, agency or
instrumentality:

               (a)  does or shall subject Agent or any Lender to any tax of any
     kind whatsoever with respect to this Agreement, the other Loan Documents or
     any Loans made or Lender Letters of Credit or Risk Participation Agreements
     issued hereunder, or change the basis of taxation of payments to Agent or
     such Lender of principal, fees, interest or any other amount payable
     hereunder (except for net income taxes, or franchise taxes imposed in lieu
     of net income or gross receipts taxes, imposed generally by federal, state
     or local taxing authorities with respect to interest or commitment or other
     fees payable hereunder or changes in the rate of tax on the overall net
     income or gross receipts of Agent or such Lender); or

               (b)  does or shall impose on Agent or any Lender any other
     condition or increased cost in connection with the transactions
     contemplated hereby or participations herein;

and the result of any of the foregoing is to increase the cost to Agent or any
such Lender of issuing any Lender Letter of Credit or Risk Participation
Agreement or making or continuing any Loan hereunder, as the case may be, or to
reduce any amount receivable hereunder, then, in any such case, Borrowers shall
promptly pay to Agent or such Lender, upon its demand, any additional amounts
necessary to compensate Agent or such Lender, on an after-tax basis, for such
additional cost or reduced amount receivable, as determined by Agent or such
Lender with respect to this Agreement or the other Loan Documents.  If Agent or
such Lender becomes entitled to claim any additional amounts pursuant to this
subsection, it shall promptly notify Borrowers of the event by reason of which
Agent or such Lender has become so entitled.  A certificate as to any additional
amounts payable pursuant to the foregoing sentence submitted by Agent or such
Lender to Borrowers and Agent shall, absent manifest error, be final, conclusive
and binding for all purposes.

                                       15
<PAGE>

          (C)   Foreign Lenders.  Each Lender organized under the laws of a
                ---------------
jurisdiction outside the United States (a "Foreign Lender") as to which payments
to be made under this Agreement or under the Notes are exempt from United States
withholding tax or are subject to United States withholding tax at a reduced
rate under an applicable statute or tax treaty shall provide to Borrower and
Agent (1) a properly completed and executed Internal Revenue Service Form 4224
or Form 1001 or other applicable form, certificate or document prescribed by the
Internal Revenue Service of the United States certifying as to such Foreign
Lender's entitlement to such exemption or reduced rate of withholding with
respect to payments to be made to such Foreign Lender under this Agreement and
under the Notes (a "Certificate of Exemption") or (2) a letter from any such
Foreign Lender stating that it is not entitled to any such exemption or reduced
rate of withholding (a "Letter of Non-Exemption").  Prior to becoming a Lender
under this Agreement and within fifteen (15) days after a reasonable written
request of Borrowers or Agent from time to time thereafter, each Foreign Lender
that becomes a Lender under this Agreement shall provide a Certificate of
Exemption or a Letter of Non-Exemption to Borrowers and Agent.

          If a Foreign Lender is entitled to an exemption with respect to
payments to be made to such Foreign Lender under this Agreement (or to a reduced
rate of withholding) and does not provide a Certificate of Exemption to
Borrowers and Agent within the time periods set forth in the preceding
paragraph, Borrowers shall withhold taxes from payments to such Foreign Lender
at the applicable statutory rates and Borrowers shall not be required to pay any
additional amounts as a result of such withholding, provided that all such
                                                    --------

Exemption to Borrowers and Agent.

          1.10  Optional Prepayment/Replacement of Lenders.  Within thirty
                ------------------------------------------
(30) days after receipt by Borrowers of written notice and demand from any
Lender for payment pursuant to subsection 1.8 or 1.9 or, as provided in
subsection 8.3(C), in the case of certain refusals by any Lender to consent to
certain proposed amendments, modifications, terminations or waivers with respect
to this Agreement that have been approved by Requisite Lenders (any such Lender
demanding such payment or refusing to consent being referred to herein as an
"Affected Lender"), Borrowers may, at their option, notify Agent and such
Affected Lender of its intention to do one of the following:

          (A)   Borrowers may obtain, at Borrowers' expense, a replacement
     Lender ("Replacement Lender") for such Affected Lender, which Replacement
     Lender shall be reasonably satisfactory to Agent. In the event Borrowers
     obtain a Replacement Lender that will refinance all outstanding Obligations
     owed to such Affected Lender and assume its Commitments hereunder within
     ninety (90) days following notice of Borrowers' intention to do so, the
     Affected Lender shall sell and assign all of its rights and delegate all of
     its obligations under this Agreement to such Replacement Lender in
     accordance with the provisions of subsection 8.1, provided that Borrowers
                                                       --------
     have reimbursed such Affected Lender for any administrative fee payable
     pursuant to subsection 8.1 and, in any case where such replacement occurs
     as the result of a demand for payment pursuant to subsection 1.8 or 1.9,
     paid all amounts required to

                                       16
<PAGE>

     be paid to such Affected Lender pursuant to subsection 1.8 or 1.9 through
     the date of such sale and assignment; or

          (B)  Borrowers may prepay in full all outstanding Obligations owed to
     such Affected Lender and terminate such Affected Lender's Pro Rata Share of
     the Revolving Loan Commitment, in which case the Revolving Loan Commitment
     will be reduced by the amount of such Pro Rata Share.  Borrowers shall,
     within ninety (90) days following notice of its intention to do so, prepay
     in full all outstanding Obligations owed to such Affected Lender
     (including, in any case where such replacement occurs as the result of a
     demand for payment for increased costs, such Affected Lender's increased
     costs for which it is entitled to reimbursement under this Agreement
     through the date of such prepayment), and terminate such Affected Lender's
     obligations under the Revolving Loan Commitment.


                                   SECTION 2

                             AFFIRMATIVE COVENANTS

          Each Borrower covenants and agrees that so long as the Revolving Loan
Commitment is in effect and until payment in full of all Obligations (other than
contingent indemnification obligations to the extent no unsatisfied claim giving
rise thereto has been asserted) and termination of all Lender Letters of Credit
and Risk Participation Agreements, unless Requisite Lenders shall otherwise give
their prior written consent, each Borrower shall perform and comply with, and
shall cause each of the other Loan Parties to perform and comply with, all
covenants in this Section 2 applicable to such Person.

          2.1  Compliance With Laws and Contractual Obligations.  Each
               ------------------------------------------------
Borrower will (a) comply with and will cause each of its Subsidiaries to comply
with (i) the requirements of all applicable laws, rules, regulations and orders
of any governmental authority (including, without limitation, laws, rules,
regulations and orders relating to taxes, employer and employee contributions,
securities, employee retirement and welfare benefits, environmental protection
matters and employee health and safety) as now in effect and which may be
imposed in the future in all jurisdictions in which Parent or its Subsidiaries
are now doing business or may hereafter be doing business and (ii) the
obligations, covenants and conditions contained in all Contractual Obligations
of such Borrower or such Subsidiary, as applicable other than those laws, rules,
regulations, orders and provisions of such Contractual Obligations the
noncompliance with which could not be reasonably expected to have, either
individually or in the aggregate, a Material Adverse Effect, and (b) maintain or
obtain and will cause each of its Subsidiaries to maintain or obtain, all
licenses, qualifications and permits now held or hereafter required to be held
by Parent and its Subsidiaries, for which the loss, suspension, revocation or
failure to obtain or renew, could reasonably be expected to have a Material
Adverse Effect.  This subsection 2.1 shall not preclude a Borrower or any
Subsidiary from contesting any taxes or other payments, if they are being
diligently contested in good faith in a manner which stays enforcement thereof
and if appropriate expense provisions have been recorded in conformity

                                       17
<PAGE>

with GAAP. Each Borrower represents and warrants that as of the date hereof, it
(i) is in compliance and each of its Subsidiaries is in compliance with the
requirements of all applicable laws, rules, regulations and orders of any
governmental authority as now in effect other than those laws, rules,
regulations, orders and provisions of such Contractual Obligations, the
noncompliance with which could not be reasonably expected to have, either
individually or in the aggregate, a Material Adverse Effect and (ii) maintains
and each of its Subsidiaries maintains all licenses, qualifications and permits
referred to above.

     "Contractual Obligations," as applied to any Person, means any indenture,
mortgage, deed of trust, contract, undertaking, agreement or other instrument to
which that Person is a party or by which it or any of its properties is bound or
to which it or any of its properties is subject including, without limitation,
the Related Transactions Documents.

          2.2  Maintenance of Properties; Insurance.  Each Borrower will
               ------------------------------------
maintain or cause to be maintained in good repair, working order and condition
all material properties used in the business of such Borrower and its
Subsidiaries and will make or cause to be made all appropriate repairs, renewals
and replacements thereof.  Each Borrower will maintain or cause to be
maintained, with financially sound and reputable insurers, public liability and
property damage insurance with respect to its business and properties and the
business and properties of its Subsidiaries against loss or damage of the kinds
customarily carried or maintained by corporations of established reputation
engaged in similar businesses and in amounts acceptable to Agent and will
deliver evidence thereof to Agent. Parent will maintain business interruption
insurance providing coverage for a period of at least six months and in an
amount not less than $7,000,000.  Borrowers shall cause Agent, pursuant to
endorsements and/or assignments in form and substance reasonably satisfactory to
Agent, to be named as lender's loss payee in the case of casualty insurance,
additional insured in the case of all liability insurance and assignee in the
case of all business interruption insurance, in each case for the benefit of
Lenders.  Each Borrower represents and warrants that it and each of its
Subsidiaries currently maintains all material properties as set forth above and
maintains all insurance described above.  In the event Borrowers fail to provide
Agent with evidence of the insurance coverage required by this Agreement, Agent
may purchase insurance at Borrowers' expense to protect Agent's interests in the
Collateral.  This insurance may, but need not, protect Borrowers' interests.
The coverage purchased by Agent may not pay any claim made by Borrowers or any
claim that is made against Borrowers in connection with the Collateral.
Borrowers may later cancel any insurance purchased by Agent, but only after
providing Agent with evidence that Borrowers have obtained insurance as required
by this Agreement.  If Agent purchases insurance for the Collateral, Borrowers
will be responsible for the costs of that insurance, including interest and
other charges imposed by Agent in connection with the placement of the
insurance, until the effective date of the cancellation or expiration of the
insurance.  The costs of the insurance may be added to the Obligations.  The
costs of the insurance may be more than the cost of insurance Borrowers are able
to obtain on their own.

          2.3  Inspection; Lender Meeting.  Each Borrower shall permit any
               --------------------------
authorized representatives of Agent to visit and inspect any of the properties
of such Borrower or any of its Subsidiaries, including its and their financial
and accounting records, and to make copies and take

                                       18
<PAGE>

extracts therefrom, and to discuss its and their affairs, finances and business
with its and their officers and certified public accountants, at such reasonable
times during normal business hours, as often as may be reasonably requested and,
provided no Default or Event of Default has occurred and is continuing, upon
reasonable prior notice. Representatives of each Lender will be permitted to
accompany representatives of Agent during each visit, inspection and discussion
referred to in the immediately preceding sentence. Without in any way limiting
the foregoing, each Borrower will participate and will cause its key management
personnel to participate in a meeting with Agent and Lenders at least once
during each year, which meeting shall be held at such time and such place as may
be reasonably requested by Agent.

          2.4  Corporate Existence.  Except as otherwise permitted by
               -------------------
subsection 3.6, each Borrower will, and will cause each of its Subsidiaries to,
at all times preserve and keep in full force and effect its corporate existence
and all rights and franchises material to its business.

          2.5  Further Assurances.
               ------------------

          (A)  Each Borrower shall and shall cause each other Loan Party (other
than Foreign Subsidiaries) to, from time to time, execute such guaranties,
financing statements, documents, security agreements and reports as Agent or
Requisite Lenders at any time may reasonably request to evidence, perfect or
otherwise implement the guaranties and security for repayment of the Obligations
contemplated by the Loan Documents.

          (B)  At Agent's or Requisite Lenders' request, Borrowers shall cause
any Domestic Subsidiaries of Parent promptly to guaranty the Obligations and to
grant to Agent, for the benefit of Agent and Lenders, a security interest in the
real, personal and mixed property of such Subsidiary to secure the Obligations
provided neither Borrowers nor any Domestic Subsidiary shall be required to
comply with any foreign law requirements necessary to perfect a security
interest in property located outside the United States if such property is not
material.  The documentation for such guaranty or security shall be
substantially similar to the Loan Documents executed concurrently herewith with
such modifications as are reasonably requested by Agent.

          (C)  At Agent's or Requisite Lenders' request, Borrowers shall engage,
or reimburse Agent or Requisite Lenders for the costs of, such legal counsel as
Agent or Requisite Lenders may request to provide opinions or such other advice
acceptable to them regarding the organization, valid existence and good standing
of Foreign Subsidiaries and the effectiveness of the pledge of the equity
securities of such Foreign Subsidiary.

          2.6  Syndication Assurances.  Notwithstanding anything to the
               ----------------------
contrary set forth  in this Agreement, Agent may change pricing and make
structural changes to the Loans and this Agreement (without affecting the total
amount of commitments hereunder) if Agent determines that such changes are
reasonably required in order to ensure successful syndication of the Loans on
the terms which are acceptable to Agent and each Borrower agrees to execute such
amendments and agreements as Agent may request to effectuate the foregoing.

                                       19

          2.7  Distributions.  Each Borrower shall, and shall cause each of
               -------------
its Subsidiaries to distribute, or cause to be distributed, not less frequently
than quarterly, to Borrowers all cash receipts, including operating cash flow,
sales proceeds and investment income, after payment of all expenses, other costs
permitted to be paid herein and after the funding of reasonable reserves and
setting aside of funds reasonably anticipated to be needed for Acquisitions
reasonably expected to be consummated and permitted hereunder.

                              NEGATIVE COVENANTS

          Each Borrower covenants and agrees that so long as the Revolving Loan
Commitment is in effect and until payment in full of all Obligations (other than
contingent indemnification obligations to the extent no unsatisfied claim giving
rise thereto has been asserted) and termination of all Lender Letters of Credit
and Risk Participation Agreements, unless Requisite Lenders shall otherwise give
their prior written consent, such Borrower shall perform and comply with, and
shall cause each of the other Loan Parties to perform and comply with, all
covenants in this Section 3 applicable to such Person.

          3.1  Indebtedness.  Each Borrower will not and will not permit any
               ------------
of its Subsidiaries directly or indirectly to create, incur, assume, or
otherwise become or remain directly or indirectly liable with respect to any

          (B)  intercompany Indebtedness from Parent to its Subsidiaries or from
     a Domestic Subsidiary to other Subsidiaries provided the aggregate amount

     outstanding $6,500,000; provided, however, that upon the request of Agent
                             --------  -------
     at any time, such Indebtedness shall be evidenced by promissory notes
     having terms reasonably satisfactory to Agent and Requisite Lenders, the
     sole originally executed counterparts of which shall be delivered to Agent,
     for the benefit of Agent and Lenders, as security for the Obligations;

          (C)  unsecured subordinated Indebtedness of Parent to Subordinated

covenant, duty or agreement contained in any of the Loan Documents, Agent may

                                   SECTION 7

          The obligations of Lenders to make Loans and of Agent to issue Lender

          7.1  Conditions to Initial Loans.  The obligations of Lenders to
               ---------------------------
make the initial Loans and of Agent to issue any Lender Letters of Credit and
Risk Participation Agreements on the Closing Date are, in addition to the
conditions precedent specified in subsection 7.2, subject to the delivery of all

          (A)  Agent shall have received, in accordance with the provisions of

of a Lender Letter of Credit or Risk Participation Agreement.

          (B)  The representations and warranties contained in Section 5 of this
Agreement and elsewhere herein and in the Loan Documents shall be (and each
request by Borrowers for a Loan or a Lender Letters of Credit and Risk
Participation Agreement shall constitute a representation and warranty by
Borrowers that such representations and warranties are) true, correct and
complete in all material respects on and as of that Funding Date to the same
extent as though made on and as of that date, except for any representation or
warranty (i) limited by its terms to a specific date and taking into account any
amendments to the Schedules or Exhibits as a result of any disclosures made

                                       44
<PAGE>

in writing by Borrower to Agent after the Closing Date and approved by Agent in
writing or (ii) not true and correct due to events or conditions, the occurrence
or existence of which are not prohibited by this Agreement or the other Loan
Documents and which do not in and of themselves constitute a Default or Event of
Default.

          (C)  No event shall have occurred and be continuing or would result
from the consummation of the borrowing contemplated (or notice requesting
issuance of a Lender Letters of Credit and Risk Participation Agreement) that
would constitute an Event of Default or a Default.

          (D)  No order, judgment or decree of any court, arbitrator or
governmental authority shall purport to enjoin or restrain any Lender from
making any Loan or Agent from issuing any Lender Letter of Credit or Risk
Participation Agreement.

                                   SECTION 8

                         ASSIGNMENT AND PARTICIPATION

          8.1  Assignments and Participations in Loans and Notes.  Each Lender
               -------------------------------------------------
(including Heller) may from time to time assign, subject to the terms of an
Assignment and Acceptance Agreement, its rights and delegate its obligations
under this Agreement to another Person, provided that (a) such Lender (excluding
                                        --------
Heller) shall first obtain the written consent of Agent, which consent shall not
be unreasonably withheld and, provided no Default or Event of Default has
occurred and is continuing, Borrowers; provided Borrowers' consent shall not be
required with respect to an assignment by a Lender to an Affiliate thereof; (b)
the Pro Rata Share of the Revolving Loan Commitment and Term Loan being assigned
shall in no event be less than the lesser of (i) $5,000,000 and (ii) the entire
amount of the Pro Rata Share of the Revolving Loan Commitment and Term Loan of
the assigning Lender; and (c) upon the consummation of each such assignment the
assigning Lender shall pay Agent an administrative fee of $3,500. The
administrative fee referred to in clause (c) of the preceding sentence shall not
apply to an assignment from a Lender to an affiliate of such Lender. In the case
of an assignment authorized under this subsection 8.1, the assignee shall have,
to the extent of such assignment, the same rights, benefits and obligations as
it would if it were an initial Lender hereunder. The assigning Lender shall be
relieved of its obligations hereunder with respect to its Pro Rata Share of the
Revolving Loan Commitment or assigned portion thereof. Each Borrower hereby
acknowledges and agrees that any assignment will give rise to a direct
obligation of Borrowers to the assignee and that the assignee shall be
considered to be a "Lender".

          Each Lender (including Heller) may sell participations in all or any
part of its Pro Rata Share of the Revolving Loan Commitment and the Term Loan to
another Person, provided that (a) such Lender (excluding Heller) shall first
                --------
obtain the prior written consent of Agent, which consent shall not be
unreasonably withheld; and (b) any such participation shall be in a minimum
amount of $5,000,000, and provided, further, that all amounts payable by
                          --------  -------
Borrowers hereunder shall be determined as if that Lender had not sold such
participation and the holder of any such participation shall not be entitled to
require such Lender to take or omit to take any action hereunder

                                       45
<PAGE>

except action directly effecting (i) any reduction in the principal amount,
interest rate or fees payable with respect to any Loan in which such holder
participates; (ii) any increase of the aggregate principal amount of the Loans;
(iii) any extension of the Expiry Date, any extension of the date on which any
Scheduled Installment is to be paid or any extension of any date fixed for any
payment of interest or fees payable with respect to any Loan in which such
holder participates; (iv) any change of the percentage of Lenders which shall be
required for Lenders or any of them to take any action hereunder; (v) any
release of Collateral (except if the sale, disposition or release of such
Collateral is permitted under subsection 3.7 or 8.2 or any other Loan Document);
(vi) any amendment or waiver of this subsection 8.1 or the definitions of the
terms used in this subsection 8.1 insofar as the definitions affect the
substance of this subsection 8.1; (vii) any consent to the assignment,
delegation or other transfer by any Loan Party of any of its rights and
obligations under any Loan Document; (viii) any change in the form in which
interest is required to be paid; and (ix) any increase in any advance rate set
forth in the Borrowing Base Certificate. Each Borrower hereby acknowledges and
agrees that any participation will give rise to a direct obligation of Borrowers
to the participant, and the participant shall for purposes of subsections 1.8,
1.9, 8.4 and 9.1 be considered to be a "Lender".

          Except as otherwise provided in this subsection 8.1 no Lender shall,
as between Borrowers and that Lender, be relieved of any of its obligations
hereunder as a result of any sale, assignment, transfer or negotiation of, or
granting of a participation in, all or any part of the Loans, the Notes or other
Obligations owed to such Lender.  Each Lender may furnish any information
concerning a Borrower and its Subsidiaries in the possession of that Lender from
time to time to assignees and participants (including prospective assignees and
participants), subject to the provisions of subsection 9.13.

          Each Borrower agrees that it will use its best efforts to assist and
cooperate with Agent and any Lender in any manner reasonably requested by Agent
or such Lender to effect the sale of a participation or an assignment described
above, including without limitation assistance in the preparation of appropriate
disclosure documents or placement memoranda.

          Agent shall provide Borrowers with written notice of the name and
address of any new Lender after the date hereof.

          Notwithstanding anything contained in this Agreement to the contrary,
so long as the Requisite Lenders shall remain capable of making LIBOR Loans, no
Person shall become a "Lender" hereunder unless such Person shall also be
capable of making LIBOR Loans.

          8.2  Agent.
               -----

          (A)  Appointment.  Each Lender hereby designates and appoints Heller
               -----------
as its Agent under this Agreement and the other Loan Documents, and each Lender
hereby irrevocably authorizes Agent to take such action or to refrain from
taking such action on its behalf under the provisions of this Agreement and the
other Loan Documents and to exercise such powers as are set forth herein or
therein, together with such other powers as are reasonably incidental thereto.
Agent

                                       46
<PAGE>

is authorized and empowered to amend, modify, or waive any provisions of this
Agreement or the other Loan Documents on behalf of Lenders subject to the
requirement that certain of Lenders' consent be obtained in certain instances as
provided in subsections 8.2, 8.3 and 9.2. Agent agrees to act as such on the
express conditions contained in this subsection 8.2. The provisions of this
subsection 8.2 are solely for the benefit of Agent and Lenders and neither
Borrowers nor any Loan Party shall have any rights as a third party beneficiary
of any of the provisions hereof. In performing its functions and duties under
this Agreement, Agent shall act solely as agent of Lenders and does not assume
and shall not be deemed to have assumed any obligation toward or relationship of
agency or trust with or for Borrowers or any other Loan Party. Agent may perform
any of its duties hereunder, or under the Loan Documents, by or through its
agents or employees.

          (B) Nature of Duties. The duties of Agent shall be mechanical and
              ----------------
administrative in nature. Agent shall not have by reason of this Agreement a
fiduciary relationship in respect of any Lender. Nothing in this Agreement or
any of the Loan Documents, express or implied, is intended to or shall be
construed to impose upon Agent any obligations in respect of this Agreement or
any of the Loan Documents except as expressly set forth herein or therein. Each
Lender shall make its own independent investigation of the financial condition
and affairs of each Borrower in connection with the extension of credit
hereunder and shall make its own appraisal of the creditworthiness of Borrowers,
and 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 (other than as expressly required herein). If Agent seeks
the consent or approval of any Lenders to the taking or refraining from taking
any action hereunder, then Agent shall send notice thereof to each Lender. Agent
shall promptly notify each Lender any time that the Requisite Lenders have
instructed Agent to act or refrain from acting pursuant hereto.

          (C) Rights, Exculpation, Etc. Neither Agent nor any of its officers,
              -------------------------
directors, employees or agents shall be liable to any Lender for any action
taken or omitted by them hereunder or under any of the Loan Documents, or in
connection herewith or therewith, except that Agent shall be liable with respect
to its own gross negligence or willful misconduct. Agent shall not be liable for
any apportionment or distribution of payments made by it in good faith and if
any such apportionment or distribution is subsequently determined to have been
made in error the sole recourse of any Lender to whom payment was due but not
made, shall be to recover from other Lenders any payment in excess of the amount
to which they are determined to be entitled (and such other Lenders hereby agree
to return to such Lender any such erroneous payments received by them). In
performing its functions and duties hereunder, Agent shall exercise the same
care which it would in dealing with loans for its own account, but Agent shall
not be responsible to any Lender for any recitals, statements, representations
or warranties herein or for the execution, effectiveness, genuineness, validity,
enforceability, collectibility, or sufficiency of this Agreement or any of the
Loan Documents or the transactions contemplated thereby, or for the financial
condition of any Loan Party. 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 Agreement or any of the Loan Documents or the financial
condition of any Loan Party, or the existence or possible existence of any
Default or Event of Default. Agent may at any time request instructions from
Lenders with respect

                                       47
<PAGE>

to any actions or approvals which by the terms of this Agreement or of any of
the Loan Documents Agent is permitted or required to take or to grant, and if
such instructions are promptly requested, Agent shall be absolutely entitled to
refrain from taking any action or to withhold any approval and shall not be
under any liability whatsoever to any Person for refraining from any action or
withholding any approval under any of the Loan Documents until it shall have
received such instructions from Requisite Lenders or all of the Lenders, as
applicable. Without limiting the foregoing, no Lender shall have any right of
action whatsoever against Agent as a result of Agent acting or refraining from
acting under this Agreement, the Notes, or any of the other Loan Documents in
accordance with the instructions of Requisite Lenders.

          (D) Reliance. Agent shall be entitled to rely, and shall be fully
              --------
protected in relying, upon any written or oral notices, statements,
certificates, orders or other documents or any telephone message or other
communication (including any writing, telex, telecopy or telegram) believed by
it in good faith to be genuine and correct and to have been signed, sent or made
by the proper Person, and with respect to all matters pertaining to this
Agreement or any of the Loan Documents and its duties hereunder or thereunder,
upon advice of counsel selected by it. Agent shall be entitled to rely upon the
advice of legal counsel, independent accountants, and other experts selected by
Agent in its sole discretion.

          (E) Indemnification. Lenders will reimburse and indemnify Agent for
              ---------------
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses (including, without limitation,
attorneys' fees and expenses), advances or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by, or asserted against Agent in
any way relating to or arising out of this Agreement or any of the Loan
Documents or any action taken or omitted by Agent under this Agreement or any of
the Loan Documents, in proportion to each Lender's Pro Rata Share, but only to
the extent that any of the foregoing is not reimbursed by Borrowers; provided,
                                                                     --------
however, that no Lender shall be liable for any portion of such liabilities,
-------
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses, advances or disbursements resulting from Agent's gross negligence or
willful misconduct. If any indemnity furnished to Agent for any purpose shall,
in the opinion of Agent, be insufficient or become impaired, Agent may call for
additional indemnity and cease, or not commence, to do the acts indemnified
against until such additional indemnity is furnished. The obligations of Lenders
under this subsection 8.2(E) shall survive the payment in full of the
Obligations and the termination of this Agreement.

          (F) Heller Individually. With respect to its obligations under the
              -------------------
Revolving Loan Commitment, the Loans made by it, and the Notes issued to it,
Heller shall have and may exercise the same rights and powers hereunder and is
subject to the same obligations and liabilities as and to the extent set forth
herein for any other Lender. The terms "Lenders" or "Requisite Lenders" or any
similar terms shall, unless the context clearly otherwise indicates, include
Heller in its individual capacity as a Lender or one of the Requisite Lenders.
Heller may lend money to, acquire equity or other ownership interests in, and
generally engage in any kind of banking, trust or other business with any Loan
Party as if it were not acting as Agent pursuant hereto.

          (G)  Successor Agent.
               ---------------

               (1) Resignation. Agent may resign from the performance of all its
                   -----------
agency functions and duties hereunder at any time by giving at least thirty (30)
Business Days' prior written notice to Borrowers and the Lenders. Such
resignation shall take effect upon the acceptance by a successor Agent of
appointment pursuant to clause (2) below or as otherwise provided below.

               (2) Appointment of Successor. Upon any such notice of resignation
                   ------------------------
pursuant to clause (1) above, Requisite Lenders shall, upon receipt of
Borrowers' prior consent which shall not be unreasonably withheld, appoint a
successor Agent. If a successor Agent shall not have been so appointed within
the thirty (30) Business Day period, referred to in clause (1) above, the
retiring Agent, upon notice to Borrowers, shall then appoint a successor Agent
who shall serve as Agent until such time, if any, as Requisite Lenders, upon
receipt of Borrowers' prior written consent which shall not be unreasonably
withheld, appoint a successor Agent as provided above.

               (3) Successor Agent. Upon the acceptance of any appointment as
                   ---------------
Agent under the Loan Documents by a successor Agent, such successor Agent shall
thereupon 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 the Loan Documents. After any retiring
Agent's resignation as Agent under the Loan Documents, the provisions of this
subsection 8.2 shall inure to its benefit as to any actions taken or omitted to
be taken by it while it was Agent under the Loan Documents.

          (H)  Collateral Matters.
               ------------------

               (1) Release of Collateral. Lenders hereby irrevocably authorize
                   ---------------------
Agent, at its option and in its discretion, to release any Lien granted to or
held by Agent upon any property covered by the Security Documents (i) upon
termination of the Revolving Loan Commitment and payment and satisfaction of all
Obligations (other than contingent indemnification obligations to the extent no
claims giving rise thereto have been asserted); (ii) constituting property being
sold or disposed of if Borrowers certify to Agent that the sale or disposition
is made in compliance with the provisions of this Agreement (and Agent may rely
in good faith conclusively on any such certificate, without further inquiry);
(iii) constituting property leased to a Borrower under a lease which has expired
or been terminated in a transaction permitted under this Agreement or is about
to expire and which has not been, and is not intended by such Borrower to be,
renewed or extended; or (iv) in accordance with the provisions of the succeeding
sentence. Agent may release or compromise any Collateral and the proceeds
thereof having a value not greater than ten percent (10%) of the total book
value of all Collateral, either in a single transaction or in a series of
related transactions, with the consent of Lenders owning an aggregate of at
least eighty percent (80%) of the Revolving Loan Commitment and the outstanding
Term Loan, provided that in no event will Agent, acting under the authority
           --------
granted to it pursuant to this sentence, release or compromise Collateral or the
proceeds

                                       49
<PAGE>

thereof having a total book value in excess of twenty percent (20%) of the book
value of all Collateral, as determined by Agent, during any calendar year.

          (2) Confirmation of Authority; Execution of Releases. Without in any
              ------------------------------------------------
manner limiting Agent's authority to act without any specific or further
authorization or consent by Lenders (as set forth in subsection 8.2(H)(1)), each
Lender agrees to confirm in writing, upon request by Agent or Borrowers, the
authority to release any property covered by the Security Documents conferred
upon Agent under clauses (i) through (iii) of subsection 8.2(H)(1). Upon receipt
by Agent of confirmation from the requisite percentage of Lenders required by
subsection 8.2(H)(1), if any, of its authority to release or compromise any
particular item or types of property covered by the Security Documents, and upon
at least ten (10) Business Days prior written request by Borrowers, Agent shall
(and is hereby irrevocably authorized by Lenders to) execute such documents as
may be necessary to evidence the release or compromise of the Liens granted to
Agent, for the benefit of Agent and Lenders, upon such Collateral, provided that
                                                                   --------
(i) Agent shall not be required to execute any such document on terms which, in
Agent's opinion, would expose Agent to liability or create any obligation or
entail any consequence other than the release or compromise of such Liens
without recourse or warranty, and (ii) such release or compromise shall not in
any manner discharge, affect or impair the Obligations or any Liens upon (or
obligations of any Loan Party, in respect of), all interests retained by any
Loan Party, including (without limitation) the proceeds of any sale, all of
which shall continue to constitute part of the property covered by the Security
Documents.

          (3) Absence of Duty. Agent shall have no obligation whatsoever to any
              ---------------
Lender or any other Person to assure that the property covered by the Security
Documents exists or is owned by a Borrower or is cared for, protected or insured
or has been encumbered or that the Liens granted to Agent have been properly or
sufficiently or lawfully created, perfected, protected or enforced or are
entitled to any particular priority, or to exercise at all or in any particular
manner or under any duty of care, disclosure or fidelity, or to continue
exercising, any of the rights, authorities and powers granted or available to
Agent in this subsection 8.2(H) or in any of the Loan Documents, it being
understood and agreed that in respect of the property covered by the Security
Documents or any act, omission or event related thereto, Agent may act in any
manner it may deem appropriate, in its discretion, given Agent's own interest in
property covered by the Security Documents as one of the Lenders and that Agent
shall have no duty or liability whatsoever to any of the other Lenders, provided
                                                                        --------
that Agent shall exercise the same care which it would in dealing with loans for
its own account.

          (I) Agency for Perfection. Agent and each Lender hereby appoint each
              ---------------------
other Lender as agent for the purpose of perfecting Agent's security interest in
assets which, in accordance with Article 9 of the Uniform Commercial Code in any
                                 ---------
applicable jurisdiction, can be perfected only by possession. Should any Lender
(other than Agent) obtain possession of any such Collateral, such Lender shall
notify Agent thereof, and, promptly upon Agent's request therefor, shall deliver
such Collateral to Agent or in accordance with Agent's instructions. Each Lender
agrees that it will not have any right individually to enforce or seek to
enforce any Security Document or to realize upon any collateral security for the
Loans unless instructed to do so by Agent, it being understood and agreed that
such rights and remedies may be exercised only by Agent.

                                       50
<PAGE>

          (J) Dissemination of Information. Agent will use its best efforts to
              ----------------------------
provide Lenders with any information received by Agent from Borrowers or any
other Loan Party which is required to be provided to a Lender hereunder,
provided that Agent shall not be liable to Lenders for any failure to do so,
--------
except to the extent that such failure is attributable to Agent's gross
negligence or willful misconduct.

          8.3 Amendments, Consents and Waivers for Certain Actions.
              ----------------------------------------------------

          (A) Except as otherwise provided in this subsection 8.3, in subsection
9.2 or in any Assignment and Acceptance Agreement and except as to matters set
forth in other subsections hereof or in any other Loan Document as requiring
only Agent's consent, the consent of Requisite Lenders and Borrowers will be
required to amend, modify, terminate, or waive any provision of this Agreement
or any of the other Loan Documents.

          (B) In the event Agent requests the consent of a Lender and does not
receive a written consent or denial thereof within ten (10) Business Days after
such Lender's receipt of such request, then such Lender will be deemed to have
denied the giving of such consent.

          (C) If, in connection with any proposed amendment, modification,
termination or waiver of any of the provisions of this Agreement as contemplated
by clauses (a) through (i) of the first proviso of subsection 9.2, the consent
of Requisite Lenders is obtained but the consent of one or more other Lenders
whose consent is required is not obtained, then Borrowers shall have the right,
so long as all non-consenting Lenders are treated as described in clauses (A) or
(B) below, to either (A) replace each such non-consenting Lender with one or
more Replacement Lenders pursuant to subsection 1.10(A) so long as each such
Replacement Lender consents to the proposed amendment, modification, termination
or waiver or (B) terminate such non-consenting Lender's Pro Rata Share of the
Revolving Loan Commitment and prepay in full its Obligations to such non-
consenting Lender, in accordance with subsection 1.10(B).

          8.4 Set Off and Sharing of Payments. In addition to any rights now
              -------------------------------
or hereafter granted under applicable law and not by way of limitation of any
such rights, during the continuance of any Event of Default, each Lender is
hereby authorized by Borrowers at any time or from time to time, with reasonably
prompt subsequent notice to Borrowers (any prior or contemporaneous notice being
hereby expressly waived) to set off and to appropriate and to apply any and all
(A) balances held by such Lender at any of its offices for the account of a
Borrower or any of its Subsidiaries (regardless of whether such balances are
then due to a Borrower or its Subsidiaries), and (B) other property at any time
held or owing by such Lender to or for the credit or for the account of a
Borrower or any of its Subsidiaries, against and on account of any of the
Obligations; except that no Lender shall exercise any such right without the
prior written consent of Agent.  Any Lender exercising a right to set off shall,
to the extent the amount of any such set off exceeds its Pro Rata Share of the
amount set off, purchase for cash (and the other Lenders shall sell) interests
in each such other Lender's Pro Rata Share of the Obligations as would be
necessary to cause such Lender to share

                                       51
<PAGE>

such excess with each other Lender in accordance with their respective Pro Rata
Shares. Each Borrower agrees, to the fullest extent permitted by law, that any
Lender may exercise its right to set off with respect to amounts in excess of
its Pro Rata Share of the Obligations and upon doing so shall deliver such
excess to the Agent for the benefit of all Lenders in accordance with their Pro
Rata Shares.

          8.5  Disbursement of Funds. Agent may, on behalf of Lenders, disburse
               ---------------------
funds to Borrowers for Loans requested. Each Lender shall reimburse Agent on
demand for all funds disbursed on its behalf by Agent, or if Agent so requests,
each Lender will remit to Agent its Pro Rata Share of any Loan before Agent
disburses same to Borrowers. If Agent elects to require that each Lender make
funds available to Agent, prior to a disbursement by Agent to Borrowers, Agent
shall advise each Lender by telephone or telecopy of the amount of such Lender's
Pro Rata Share of the Loan requested by Parent, on behalf of Borrowers, no later
than 1:00 p.m. Chicago time on the Funding Date applicable thereto, and each
such Lender shall pay Agent such Lender's Pro Rata Share of such requested Loan,
in same day funds, by wire transfer to Agent's account on such Funding Date. If
any Lender fails to pay the amount of its Pro Rata Share within one (1) Business
Day after Agent's demand, Agent shall promptly notify Borrowers, and Borrowers
shall immediately repay such amount to Agent. Any repayment required pursuant to
this subsection 8.5 shall be without premium or penalty. Nothing in this
subsection 8.5 or elsewhere in this Agreement or the other Loan Documents,
including without limitation the provisions of subsection 8.6, shall be deemed
to require Agent to advance funds on behalf of any Lender or to relieve any
Lender from its obligation to fulfill its commitments hereunder or to prejudice
any rights that Agent or Borrowers may have against any Lender as a result of
any default by such Lender hereunder.

          8.6  Disbursements of Advances; Payment.
               ----------------------------------

          (A)  Revolving Loan Advances, Payments and Settlements; Interest and
               ---------------------------------------------------------------
Fee Payments.
------------

               (1)  The Revolving Loan balance may fluctuate from day to day
through Agent's disbursement of funds to, and receipt of funds from, Borrowers.
In order to minimize the frequency of transfers of funds between Agent and each
Lender notwithstanding terms to the contrary set forth in Section 1 or
subsection 8.5, Revolving Loan advances and payments will be settled among Agent
and Lenders according to the procedures described in this subsection 8.6.
Notwithstanding these procedures, each Lender's obligation to fund its portion
of any advances made by Agent to Borrowers will commence on the date such
advances are made by Agent. Such payments will be made by such Lender without
set-off, counterclaim or reduction of any kind.

               (2)  On the second (2nd) Business Day of each week, or more
frequently (including daily), if Agent so elects (each such day being a
"Settlement Date"), Agent will advise each Lender by telephone or telecopy of
the amount of each such Lender's Pro Rata Share of the Revolving Loan balance as
of the close of business of the (2nd) second Business Day immediately preceding
the Settlement Date. In the event that payments are necessary to adjust the
amount of such

                                       52
<PAGE>

Lender's required Pro Rata Share of the Revolving Loan balance to such Lender's
actual Pro Rata Share of the Revolving Loan balance as of any Settlement Date,
the party from which such payment is due will pay the other, in same day funds,
by wire transfer to the other's account not later than 3:00 p.m. Chicago time on
the Business Day following the Settlement Date.

               (3) For purposes of this subsection 8.6(A)(3), the following
terms and conditions will have the meanings indicated:

               (a) "Daily Loan Balance" means an amount calculated as of the end
     of each calendar day by subtracting (i) the cumulative principal amount
     paid by Agent to a Lender on a Loan from the Closing Date through and
     including such calendar day, from (ii) the cumulative principal amount on a
     Loan advanced by such Lender to Agent on that Loan from the Closing Date
     through and including such calendar day.

               (b) "Daily Interest Rate" means an amount calculated by dividing
     the interest rate payable to a Lender on a Loan (as set forth in subsection
     1.2) as of each calendar day by three hundred sixty (360).

               (c) "Daily Interest Amount" means an amount calculated by
     multiplying the Daily Loan Balance of a Loan by the associated Daily
     Interest Rate on that Loan.

               (d) "Interest Ratio" means a number calculated by dividing the
     total amount of the interest on a Loan received by Agent with respect to
     the immediately preceding month by the total amount of interest on that
     Loan due from Borrower during the immediately preceding month.

On the first (1st) Business Day of each month ("Interest Settlement Date"),
Agent will advise each Lender by telephone, telex, or telecopy of the amount of
such Lender's Pro Rata Share of interest and fees on each of the Loans as of the
end of the last day of the immediately preceding month. Provided that such
Lender has made all payments required to be made by it under this Agreement,
Agent will pay to such Lender, by wire transfer to such Lender's account (as
specified by such Lender on the signature page of this Agreement or the
applicable Assignment and Acceptance Agreement, as amended by such Lender from
time to time after the date hereof pursuant to the notice provisions contained
herein or in the applicable Assignment and Acceptance Agreement) not later than
3:00 p.m. Chicago time on the next Business Day following the Interest
Settlement Date, such Lender's Pro Rata Share of interest and fees on each of
the Loans. Such Lender's Pro Rata Share of interest on each Loan will be
calculated for that Loan by adding together the Daily Interest Amounts for each
calendar day of the prior month for that Loan and multiplying the total thereof
by the Interest Ratio for that Loan. Such Lender's Pro Rata Share of each of the
commitment fee described in subsection 1.2(B) and the Risk Participation
Liability fee described in subsection 1.2(C) shall be paid and

                                       53
<PAGE>

calculated in a manner consistent with the payment and calculation of interest
as described in this subsection 8.6(A).

          (B)  Term Loan Principal Payments. Payments of principal of the Term
               ----------------------------
Loan will be settled on the date of receipt if received by Agent on the first
Business Day of a month and on the Business Day immediately following the date
of receipt if received by Agent on any day other than the first Business Day of
a month.

          (C)  Availability of Lender's Pro Rata Share.
               ---------------------------------------

               (1)  Unless Agent shall have received notice from a Lender prior
to a Funding Date that such Lender will not make available its Pro Rata Share of
a Loan requested by Parent, on behalf of Borrowers, Agent may assume that such
Lender has made such amount available to Agent on the Business Day following the
next Settlement Date. If a Lender has not in fact made its Pro Rata Share
available to the Agent on such date, then such Lender and Borrowers severally
agree to pay to Agent forthwith on demand such amount without set-off,
counterclaim or deduction of any kind, together with interest thereon, for each
day from and including the date such amount is made available to Agent by such
Lender to but excluding the date of payment to Agent, at (a) in the case of such
Lender, the greater of the Federal Funds Effective Rate and a rate determined by
Agent in accordance with banking industry rules on interbank compensation or (b)
in the case of Borrowers, the interest rate applicable under this Agreement with
respect to such Loan. Until any such amount is paid to Agent, Agent shall not be
obligated to submit to such Lender any payment made by Borrowers to Agent with
respect to any Loan or any fees or other payments with respect thereto.

               (2)  Nothing contained in this subsection 8.6(C) will be deemed
to relieve a Lender of its obligation to fulfill its commitments or to prejudice
any rights Agent or Borrowers may have against such Lender as a result of any
default by such Lender under this Agreement.

               (3)  Without limiting the generality of the foregoing, each
Lender shall be obligated to fund its Pro Rata Share of any Revolving Loan made
after any Event of Default or acceleration of the Obligations with respect to
any draw on a Lender Letter of Credit or a Risk Participation Agreement.

          (D)  Return of Payments
               ------------------

               (1)  If Agent pays an amount to a Lender under this Agreement in
the belief or expectation that a related payment has been or will be received by
Agent from Borrowers and such related payment is not received by Agent, then
Agent will be entitled to recover such amount from such Lender without set-off,
counterclaim or deduction of any kind together with interest thereon, for each
day from and including the date such amount is made available by Agent to such
Lender to but excluding the date of repayment to Agent, at the greater of the
Federal Funds Effective Rate and a rate determined by Agent in accordance with
banking industry rules on interbank compensation.

                                       54
<PAGE>

               (2)  If Agent determines at any time that any amount received by
Agent under this Agreement must be returned to a Borrower or paid to any other
person pursuant to any requirement of law, court order or otherwise, then,
notwithstanding any other term or condition of this Agreement, Agent will not be
required to distribute any portion thereof to any Lender. In addition, each
Lender will repay to Agent on demand any portion of such amount that Agent has
distributed to such Lender, together with interest at such rate, if any, as
Agent is required to pay to a Borrower or such other Person, without set-off,
counterclaim or deduction of any kind.

                                   SECTION 9

                                 MISCELLANEOUS

          9.1  Indemnities. Each Borrower agrees to indemnify, pay, and hold
               -----------
Agent, each Lender and their respective officers, directors, employees, agents,
and attorneys (the "Indemnitees") harmless from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits
and claims of any kind or nature whatsoever that may be imposed on, incurred by,
or asserted against the Indemnitee as a result of its being a party to this
Agreement or the transactions consummated pursuant to this Agreement; provided
                                                                      --------
that Borrowers shall have no obligation to an Indemnitee hereunder with respect
to liabilities arising from the gross negligence or willful misconduct of that
Indemnitee as determined by a court of competent jurisdiction. This subsection
and other indemnification provisions contained within the Loan Documents shall
survive the termination of this Agreement.

          9.2  Amendments and Waivers. Except as otherwise provided herein, no
               ----------------------
amendment, modification, termination or waiver of any provision of this
Agreement, the Notes or any of the other Loan Documents, or consent to any
departure by any Loan Party therefrom, shall in any event be effective unless
the same shall be in writing and signed by Requisite Lenders (or Agent, if
expressly set forth herein, in any Note or in any other Loan Document) and the
applicable Loan Party; provided, that except to the extent permitted by the
                       --------
applicable Assignment and Acceptance Agreement, no amendment, modification,
termination or waiver shall, unless in writing and signed by all Lenders, do any
of the following: (a) increase any Lender's Pro Rata Share of the Revolving Loan
Commitment; (b) reduce the principal of, rate of interest on or fees payable
with respect to any Loan; (c) extend the Expiry Date, extend the date on which
any Scheduled Installment is to be paid or extend any date fixed for any payment
of interest or fees; (d) change the percentage of Lenders which shall be
required for Lenders or any of them to take any action hereunder; (e) release
Collateral (except if the sale, disposition or release of such Collateral is
permitted under subsection 3.7 or 8.2 or any other Loan Document); (f) amend or
waive this subsection 9.2 or the definitions of the terms used in this
subsection 9.2 insofar as the definitions affect the substance of this
subsection 9.2; (g) consent to the assignment, delegation or other transfer by
any Loan Party of any of its rights and obligations under any Loan Document; (h)

                                       55
<PAGE>

and provided, further, that no amendment, modification, termination or waiver
    --------  -------
affecting the rights or duties of Agent under any Loan Document shall in any
event be effective, unless in writing and signed by Agent, in addition to
Lenders required hereinabove to take such action. Each amendment, modification,
termination or waiver shall be effective only in the specific instance and for
the specific purpose for which it was given. No amendment, modification,
termination or waiver shall be required for Agent to take additional Collateral
pursuant to any Loan Document. No amendment, modification, termination or waiver
of any provision of any Note shall be effective without the written concurrence
of the holder of that Note. No notice to or demand on Borrowers or any other
Loan Party in any case shall entitle a Borrower or any other Loan Party to any
other or further notice or demand in similar or other circumstances. Any
amendment, modification, termination, waiver or consent effected in accordance
with this subsection 9.2 shall be binding upon each holder of the Notes at the
time outstanding, each future holder of the Notes, and, if signed by a Loan
Party, on such Loan Party.

          9.3  Notices. Any notice or other communication required shall be
               -------

                                                               Chicago, Illinois

     FOR VALUE RECEIVED, the undersigned, OPINION RESEARCH CORPORATION, a
Delaware corporation and ORC, INC., a Delaware corporation (together, the
"Borrowers"), hereby unconditionally promise to pay to the order of
____________________________, a _________ corporation ("Lender"), at Agent's
office at 500 West Monroe Street, Chicago, Illinois 60661, or at such other
place as the Agent may from time to time designate in writing, in lawful money
of the United States of America and in immediately available funds, the
principal sum of ___________________ AND NO/100 DOLLARS ($__________________),
or, if less, the aggregate unpaid principal amount of all advances made pursuant
to subsection 1.1(B) of the "Credit Agreement" (as hereinafter defined), at such
times as are specified in, and in accordance with the provisions of, the Credit
Agreement. This Revolving Note is referred to in and was executed and delivered
pursuant to that certain Credit Agreement of even date herewith (the "Credit
Agreement") among Borrowers, Heller Financial, Inc., as Agent for the benefit of
all lenders, and the other lenders who are parties thereto, to which reference
is hereby made for a statement of the terms and conditions under which the
Revolving Loan evidenced hereby was made and is to be repaid. All terms which
are capitalized and used herein (which are not otherwise specifically defined
herein) and which are defined in the Credit Agreement shall be used in this
Revolving Note as defined in the Credit Agreement. This Revolving Note is
secured by the Collateral.

     Borrowers further promise to pay interest on the outstanding unpaid
principal amount hereof, as provided in the Credit Agreement, from the date
hereof until payment in full hereof at the applicable rate specified in
subsection 1.2(A) of the Credit Agreement; provided, however, that if Agent, or
Requisite Lenders, so elect, following the occurrence and during the continuance
of an Event of Default, Borrowers promise to pay to Lender interest on the
unpaid principal amount hereof at the applicable rate specified in subsection
1.2(E) of the Credit Agreement. Interest shall be payable in arrears on the
dates specified in subsection 1.2(D) of the Credit Agreement and at maturity,
whether by acceleration or otherwise. Interest shall be computed on the closing
daily principal balance in Borrowers' Loan Account with respect to Revolving
Loan on the basis of a 360 day year for the actual number of days elapsed in the
period during which it accrues.

     If a payment hereunder becomes due and payable on a day that is not a
Business Day, the payment may be made on the next succeeding Business Day, and
such extension of time shall be included in the computation of the amount of
interest due on such succeeding Business Day. Checks, drafts or similar items of
payment received by Lender shall not constitute payment, but credit therefor
shall, solely for the purpose of computing interest earned by Lender, be given
in accordance with the Credit Agreement. In no contingency or event whatsoever
shall interest charged hereunder, however such interest may be characterized or
computed, exceed the highest rate
<PAGE>

permissible under any law which a court of competent jurisdiction determines is
applicable hereto. In the event of any such determination, the provisions of
subsection 1.2(F) of the Credit Agreement shall govern and control.

     After the occurrence and during the continuance of an Event of Default,
Agent shall have the exclusive right to apply and to reapply any and all
payments hereunder against the Obligations of Borrowers in such manner as Agent
deems advisable notwithstanding any previous entry by Agent upon Borrowers' Loan
Account or any other books and records.

     If any suit or action is instituted or attorneys are employed to collect
this Revolving Note or any part thereof, Borrowers hereby promise and agree to
pay all costs of collection, including attorneys' fees and court costs.

     Each Borrower and each endorser, guarantor and surety of this Revolving
Note hereby waives presentment for payment, protest and demand, and notice of
demand, protest, dishonor and nonpayment of this Revolving Note. Except as
otherwise required pursuant to the Credit Agreement, each Borrower also waives
all rights to notice and hearing of any kind upon the occurrence of an Event of
Default and prior to the exercise by Agent of its rights to repossess the
Collateral without judicial process or to replevy, attach or levy upon the
Collateral without notice or hearing.

     THIS REVOLVING NOTE HAS BEEN DELIVERED AT AND SHALL BE DEEMED TO HAVE BEEN
MADE AT CHICAGO, ILLINOIS AND SHALL BE INTERPRETED AND THE RIGHTS AND
LIABILITIES OF THE PARTIES HERETO SHALL BE DETERMINED IN ACCORDANCE WITH THE
INTERNAL LAWS AND DECISIONS OF THE STATE OF ILLINOIS WITHOUT REGARD TO CONFLICTS
OF LAW PROVISIONS. Whenever possible each provision of this Revolving Note shall
be interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Revolving Note shall be prohibited by or invalid
under applicable law, such provision shall be ineffective to the extent of such
prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions of this Revolving Note. Whenever in this Revolving
