Rate Loan (the events described in clauses (ii) and (iii) hereof, being "Other
Indemnity Events").  The amount of such loss shall be calculated by multiplying
the principal amount of the repayment or prepayment or the amount which is the
subject of an Other Indemnity Event by the per annum rate (expressed as a

Rate"), determined by subtracting (A) the highest asked yield most recently

Indemnity Event, said Repayment Indemnity to accrue for a period from and
including the date of the repayment or prepayment or Other Indemnity Event to,
but excluding, the date of expiration of the Average Term, as if such term
commenced on the date of repayment or prepayment or Other Indemnity Event;
provided that no Repayment Indemnity shall be payable unless the foregoing
calculation of the Indemnity Rate produces a positive number.  The Borrowers
agree that the Repayment Indemnity has been freely bargained between the parties
to provide the Agent and the Banks with compensation for the costs of
reinvesting the Credit Facility proceeds and the loss of the contracted-for
return on the Credit Facilities and such Repayment Indemnity is reasonable and
constitutes a means of providing the Agent and the Banks with a substitute or
alternate source of cash flow if any Adjusted LIBOR Rate Loan is repaid, prepaid
or converted or if there is a failure to borrow, continue or convert as set
forth above.  The Agent's reasonable determination of the Repayment Indemnity

this Agreement and the other Loan Documents. Prepayments shall be applied in the

set forth below, selected by the Borrowers in a Borrowing Request, on the daily
unpaid balance, which interest shall be payable quarterly as to Term Loans which
are Base Rate Loans at the times principal is payable or, as to Term Loans which
are Adjusted LIBOR Rate Loans, at end of each Interest Period (except as to an
Interest Period of six (6) months, in which case interest shall be payable at
the end of each three (3) month period). The per annum interest rate on each
Term Loan shall be equal to (a) the Base Rate plus the Applicable Base Rate
                                              ----                        
Margin, or (b) the Adjusted LIBOR Rate for the applicable Interest Period plus
                                                                          ----
the Applicable Eurodollar Margin.  The Borrowing Request (which shall be made by
Research on behalf of the other Borrowers) shall designate the applicable
interest rate and Interest Period (if any), and amount of the Term Loans (which
shall be not less than $500,000 or multiples thereof) which shall bear interest
at the rates selected.  A Borrowing Request (i) as to Term Loans which are
Adjusted LIBOR Rate Loans which are to be continued as such for the next
Interest Period or as to Term Loans which are Base Rate Loans which are to be
converted to Adjusted LIBOR Rate Loans, shall be provided to the Agent not less
than three (3) Business Days prior to the requested date of continuation or

                                      42
<PAGE>

conversion and (ii) as to Adjusted LIBOR Rate Loans which are to be converted to
Base Rate Loans, not less than one (1) Business Day prior to the end of the then
pending Interest Period.  Conversions to Adjusted LIBOR Rate Loans shall only be
made (a) on a Business Day and (b) if no Default or Event of Default has
occurred and is continuing.  Conversions from Adjusted LIBOR Rate Loans to Base
Rate Loans shall only be made on the last day of the Interest Period applicable
to such Adjusted LIBOR Rate Loans.  If no notice is provided by the Borrowers as
to any Term Loan which is an Adjusted LIBOR Rate Loan prior to the end of the
then pending Interest Period, such Term Loan shall, at the end of such Interest
Period, automatically become a Base Rate Loan.  No more than five (5) Term Loans
bearing interest based upon the Adjusted LIBOR Rate may be outstanding at any
one time.  All interest computation on the Term Loans shall be on the basis of a
year of 360 days, for the actual number of days (including the first day but
excluding the last day) occurring in the period for which such interest is
payable.

          (C) Amortization.  The principal balance of the Term Loans shall be
              ------------                                                  
payable in consecutive equal quarterly installments of principal, commencing on
the first Business Day of September, 1998 and continuing on the first Business
Day of December, March, June and September thereafter until the Term Loan
Maturity Date, each such installment being equal to 1/20th of the original
principal balance of the Term Loans and being sufficient to fully amortize the
Term Loans by the Term Loan Maturity Date.  Any remaining outstanding principal
balances of Term Loans shall be payable in full on the Term Loan Maturity Date.

          (D) Optional Prepayments.  The Borrowers  may, upon not less than one
              --------------------                                            
(1) Business Day's prior written notice to the Agent, prepay the outstanding
principal amount of any Term Loan, in whole or in part, with accrued interest to
the date of such prepayment on the

                                      43
<PAGE>

amount prepaid; provided, that any prepayment as to portions of the Term Loans
which are Adjusted LIBOR Rate Loans made other than at the end of an Interest
Period shall be accompanied by the Repayment Indemnity and each partial
prepayment shall be in a principal amount of not less than $500,000 (or such
lesser amount as shall be the remaining outstanding principal balance on such
Term Loans) and such prepayments shall be applied to principal installments in
the inverse order of their maturities. Any amounts so prepaid may not be
reborrowed.

          (E) Place and Manner of Payment.  All amounts of principal and
              ---------------------------                              
interest repaid under the Term Loans must be received by the Agent in
immediately available funds, before 1:00 p.m., then prevailing New York time, to
be applied towards payment of the Term Loans on the Business Day received.
Amounts received thereafter shall be applied towards repayment of the Term Loans
on the next Business Day.

     2.3.  LETTERS OF CREDIT
           ----------------

           I.  Issuances of Letters of Credit. (a) Subject to and upon the terms
               ------------------------------
and conditions set forth herein, the Borrowers may request that any Issuing Bank
issue, at any time and from time to time on and after the Closing Date and prior
to the tenth day prior to the Revolving Credit Facility Maturity Date, for the
account of the Borrowers and for the benefit of any holder (or any trustee,
agent or other similar representative for any such holders) of L/C Supportable
Obligations of the Borrowers, an irrevocable sight standby letter of credit, in
a form customarily used by such Issuing Bank or in such other form as has been
approved by such Issuing Bank (each such standby letter of credit, a "Letter of
Credit") in support of such L/C Supportable Obligations. All Letters of Credit
shall be denominated in Dollars.

                                      44
<PAGE>

           (b)  Subject to and upon the terms and conditions set forth herein,
each Issuing Bank hereby agrees that it will, at any time and from time to time
on and after the Closing Date and prior to the tenth day prior to the Revolving
Credit Facility Maturity Date, following its receipt of the respective Letter of
Credit Request, issue for the account of the Borrowers, one or more Letters of
Credit in support of such L/C Supportable Obligations of the Borrower or any
Subsidiaries as are permitted to remain outstanding without giving rise to a
Default or an Event of Default, provided that the respective Issuing Bank shall
                                --------                                      
be under no obligation to issue any Letter of Credit if at the time of such
issuance:

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

          (ii) such Issuing Bank shall have received notice from the Required
Banks prior to the issuance of such Letter of Credit of the type described in
the second sentence

                                      45
<PAGE>

of Section 2.4(b) hereof and the matters identified in such notice have not
previously been waived or cured.

     II.  Maximum Letter of Credit Outstandings; Final Maturities.
          -------------------------------------------------------
Notwithstanding anything to the contrary contained in this Agreement, (i) no
Letter of Credit shall be issued the Stated Amount of which, when added to the
Letter of Credit Outstandings (exclusive of Unpaid Drawings which are repaid on
the date of, and prior to the issuance of, the respective Letter of Credit) at
such time would exceed either (x) $2,000,000 or (y) when added to the aggregate
principal amount of all Revolving Credit Advances then outstanding an amount
equal to the Maximum Amount and (ii) each Letter of Credit shall by its terms
terminate on or before the earlier of (A) the date which occurs one year after
the date of the issuance thereof (although any such Letter of Credit may be
extendible for successive periods of up to one year, but not beyond the tenth
Business Day prior to the Revolving Credit Facility Maturity Date, on terms
acceptable to the Issuing Bank thereof) and (B) the tenth Business Day prior to
the Revolving Credit Facility Maturity Date.

     2.4.  LETTER OF CREDIT REQUESTS.
           -------------------------

     (a)  Whenever the Borrowers desire that a Letter of Credit be issued for
their account, the Borrowers shall give the Agent and the respective Issuing
Bank at least two Business Days' (or such shorter period as is acceptable to the
respective Issuing Bank) written notice thereof.  Each notice shall be in the
form of EXHIBIT A attached hereto (each a "Letter of Credit Request").

     (b)  The making of each Letter of Credit Request shall be deemed to be a
representation and warranty by the Borrowers that such Letter of Credit may be
issued in accordance with, and will not violate the requirements of, Section 2.3
II hereof.  Unless the

                                      46
<PAGE>

respective Issuing Bank has received notice from the Required Banks before it
issues a Letter of Credit that one or more of the conditions specified in
Section 2.12 hereof are not satisfied on the Closing Date or Section 2.13 hereof
are not then satisfied, or that the issuance of such Letter of Credit would
violate Section 2.3 II hereof then, subject to the terms and conditions of this
Agreement, such Issuing Bank shall issue the requested Letter of Credit for the
account of the Borrowers in accordance with such Issuing Bank's usual and
customary practices. Upon the issuance of or amendment or modification to a
Letter of Credit, the respective Issuing Bank shall promptly notify the
Borrowers, the Agent and the Banks of such issuance, amendment or modification
and such notification shall be accompanied by a copy of the issued Letter of
Credit or amendment or modification.

     2.5.  LETTER OF CREDIT PARTICIPANTS.
           -----------------------------

     (a) Immediately upon the issuance by the respective Issuing Bank of any
Letter of Credit, such Issuing Bank shall be deemed to have sold and transferred
to each Bank with a Revolving Credit Commitment, other than such Issuing Bank
(each such Bank, in its capacity under this Section 2.5, an "L/C Participant"),
and each L/C Participant shall be deemed irrevocably and unconditionally to have
purchased and received from such Issuing Bank, without recourse or warranty, an
undivided interest and participation, to the extent of such L/C Participant's
Proportionate Share, in such Letter of Credit, each drawing or payment made
thereunder and the obligations of the Borrowers under this Agreement with
respect thereto, and any security therefor or guaranty pertaining thereto.  Upon
any change in the Revolving Credit Commitments of the Banks pursuant to this
Agreement, it is hereby agreed that, with respect to all outstanding Letters of
Credit and Unpaid Drawings, there shall be an automatic adjustment to

                                      47
<PAGE>

the participations pursuant to this Section 2.5 to reflect the new adjusted
Proportionate Shares of the assignor and assignee Bank, as the case may be.

     (b)  In determining whether to pay under any Letter of Credit, the
respective Issuing Bank shall have no obligation relative to the other Banks
other than to confirm that any documents required to be delivered under such
Letter of Credit appear to have been delivered and that they appear to
substantially comply on their face with the requirements of such Letter of
Credit. Any action taken or omitted to be taken by any Issuing Bank under or in
connection with any Letter of Credit if taken or omitted in the absence of gross
negligence or willful misconduct, as determined by a court competent
jurisdiction, shall not create for such Issuing Bank any resulting liability to
the Borrowers, any Bank or any other Person.

     (c)  In the event that any Issuing Bank makes any payment under any Letter
of Credit and the Borrowers shall not have reimbursed such amount in full to
such Issuing Bank pursuant to this Agreement, such Issuing Bank shall promptly
notify the Agent, which shall promptly notify each L/C Participant of such
failure, and each L/C Participant shall promptly and unconditionally pay to such
Issuing Bank the amount of such L/C Participant's Proportionate Share of such
unreimbursed payment in Dollars and in same day funds. If the Agent so notifies,
prior to 11:00 A.M. (New York time) on any Business Day, any L/C Participant
required to fund a payment under a Letter of Credit, such L/C Participant shall
make available to such Issuing Bank in Dollars such L/C Participant's
Proportionate Share of the amount of such payment on such Business Day in same
day funds. If and to the extent such L/C Participant shall not have so made its
Proportionate Share of the amount of such payment available to such Issuing
Bank, such L/C Participant agrees to pay to such Issuing Bank, forthwith on
demand such amount, together

                                      48
<PAGE>

with interest thereon, for each day from such date until the date such amount is
paid to such Issuing Bank at the Federal Funds Rate. The failure of any L/C
Participant to make available to such Issuing Bank its Proportionate Share of
any payment under any Letter of Credit shall not relieve any other L/C
Participant of its obligation hereunder to make available to such Issuing Bank
its Proportionate Share of any Letter of Credit on the date required, as
specified above, but no L/C Participant shall be responsible for the failure of
any other L/C Participant to make available to such Issuing Bank such other L/C
Participant's Proportionate Share of any such payment.

     (d)  Whenever any Issuing Bank receives a payment of a reimbursement
obligation as to which it has received any payments from the L/C Participants
pursuant to clause (c) above, such Issuing Bank shall pay to each L/C
Participant which has paid its Proportionate Share thereof, in Dollars and in
same day funds, an amount equal to such L/C Participant's share (based upon the
proportionate aggregate amount originally funded by such L/C Participant to the
aggregate amount funded by all L/C Participants) of the principal amount of such
reimbursement obligation and interest thereon accruing after the purchase of the
respective participations.

     (e)  Upon the request of any L/C Participant, each Issuing Bank shall
furnish to such L/C Participant copies of any Letter of Credit issued by it and
such other documentation as may reasonably be requested by such L/C Participant.

     (f)  The obligations of the L/C Participants to make payments to each
Issuing Bank with respect to Letters of Credit issued by it shall be irrevocable
and not subject to any qualification or exception whatsoever (except as
otherwise expressly provided in the last sentence of Section 2.3(b) hereof) and
shall be made in accordance with the terms and conditions

                                      49
<PAGE>

of this Agreement under all circumstances, including, without limitation, any of
the following circumstances:

          (i)   any lack of validity or enforceability of this Agreement or any
of the other Loan Documents;

          (ii)  the existence of any claim, setoff, defense or other right which
the Borrowers or any Subsidiaries may have at any time against a beneficiary
named in a Letter of Credit, any transferee of any Letter of Credit (or any
Person for whom any such transferee may be acting), the Agent, any L/C
Participant, or any other Person, whether in connection with this Agreement, any
Letter of Credit, the transactions contemplated herein or any unrelated
transactions (including any underlying transaction between the Borrowers or any
Subsidiary and the beneficiary named in any such Letter of Credit);

          (iii) any draft, certificate or any other document presented under any
Letter of Credit proving to be forged, fraudulent, invalid or insufficient in
any respect or any statement therein being untrue or inaccurate in any respect;

          (iv)  the surrender or impairment of any security for the performance
or observance of any of the terms of any of the Credit Documents; or

          (v)   the occurrence of any Default or Event of Default.

     2.6.  AGREEMENT TO REPAY LETTER OF CREDIT DRAWINGS.
           --------------------------------------------

     (a)   The Borrowers hereby jointly and severally agree to reimburse the
respective Issuing Bank, by making payment to the Agent in immediately available
funds, for any payment or disbursement made by such Issuing Bank under any
Letter of Credit issued by it (each such amount so paid until reimbursed, an
"Unpaid Drawing"), immediately after, and in any event on

                                      50
<PAGE>

the date of, such payment or disbursement, with interest on the amount so paid
or disbursed by such Issuing Bank, to the extent not reimbursed prior to 2:00
P.M. (New York time) on the date of such payment or disbursement, from and
including the date paid or disbursed to but excluding the date such Issuing Bank
was reimbursed by the Borrowers therefor at a rate per annum which shall be the
Base Rate in effect from time to time plus the Applicable Base Rate Margin;
provided, however, to the extent such amounts are not reimbursed prior to 2:00
--------  -------
p.m. (New York time) on the third Business Day following the receipt by the
Borrowers of notice of such payment or disbursement or following the occurrence
of a Default or an Event of Default under Article VII hereof, interest shall
thereafter accrue on the amounts so paid or disbursed by such Issuing Bank (and
until reimbursed by the Borrowers) at the Default Rate, in each such case, with
interest to be payable on demand. The respective Issuing Bank shall give the
Borrowers prompt written notice of each drawing under any Letter of Credit,
provided that the failure to give any such notice shall in no way affect, impair
--------                                                                       
or diminish the Borrowers' obligations hereunder.

     (b)  The obligations of the Borrowers under this Section 2.6 to reimburse
the respective Issuing Bank with respect to Unpaid Drawings (including, in each
case, interest thereon) shall be absolute and unconditional under any and all
circumstances, including, without limitation, any of the following
circumstances:

          (i)   any lack of validity or enforceability of this Agreement or any
of the other Loan Documents;

          (ii)  the existence of any claim, setoff, defense or other right which
the Borrowers or any Subsidiary may have at any time against a beneficiary named
in a Letter of Credit, any transferee of any Letter of Credit (or any Person for
whom any such transferee may be acting),

                                      51
<PAGE>

the Agent, any L/C Participant, or any other Person, whether in connection with
this Agreement, any Letter of Credit, the transactions contemplated herein or
any unrelated transactions (including any underlying transaction between the
Borrowers or any Subsidiary and the beneficiary named in any such Letter of
Credit);

          (iii) any draft, certificate or any other document presented under
any Letter of Credit proving to be forged, fraudulent, invalid or insufficient
in any respect or any statement therein being untrue or inaccurate in any
respect; or

          (iv)  the surrender or impairment of any security for the performance
or observance of any of the terms of any of the Loan Documents; provided,
however, that the Borrowers shall not be obligated to reimburse any Issuing Bank
for any wrongful payment made by such Issuing Bank under a Letter of Credit as a
result of acts or omissions constituting willful misconduct or gross negligence,
as determined by a court of competent jurisdiction, on the part of such Issuing
Bank.

     2.7.  FEES
           ----

           (A) Revolving Credit Facility Commitment Fee.  The Borrowers agree to
               ----------------------------------------                        
pay to the Agent for the ratable benefit of the Banks a commitment fee, payable
quarterly in arrears within ten (10) days after the last Business Day of each
quarter (and upon reduction and/or termination of the Revolving Credit
Commitments), equal to one quarter percent (1/4%) per annum of the actual
average unused portion of the Revolving Credit Facility over the particular
quarter.

                                      52
<PAGE>

           (B) Closing Fee.  On the Closing Date, the Borrowers shall pay to the
               -----------                                                     
Agent for the ratable benefit of the Banks a closing fee of $80,000.

           (C) Agent Fee.  Contemporaneous with the execution hereof and on each
               ---------                                                       
annual anniversary of the Closing Date, the Borrowers shall pay to the Agent,
for its own account, the Agent Fee.

           (D) Fronting Fee(s); Standby Fee(s).  The Borrowers agree to pay (i)
               -------------------------------                                
to each Issuing Bank upon issuance or renewal, for its own account, a fronting
fee in respect of each Letter of Credit issued by such Issuing Bank equal to 1/8
of one percent of the Stated Amount of such Letter of Credit (the "Fronting
Fee"), and (ii) to the Agent (for the ratable benefit of the Banks) a standby
fee (the "Standby Fee") for the period from and including the date of issuance
or renewal of such Letter of Credit to and including the date of the termination
of such Letter of Credit equal to the average daily Stated Amount of such Letter
of Credit times the Applicable Eurodollar Margin.  Accrued Standby Fees shall be
due and payable quarterly in arrears on each date interest is payable and upon
the first day after the termination of the Revolving Credit Commitments upon
which no Letters of Credit remain outstanding.

          (E) Other Letter of Credit Fees.  The Borrowers agree to pay, upon
              ---------------------------                                  
each drawing under, issuance of, or amendment to, any Letter of Credit, such
amount as shall at the time of such event be the customary scheduled
administrative charge which the applicable Issuing Bank is generally imposing in
connection with such occurrence with respect to letters of credit.

                                      53
<PAGE>

     2.8.  MANNER OF PAYMENT
           -----------------

           (A) Payments of (i) principal and interest to be made by the
Borrowers with respect to the Notes and Letter of Credit Outstandings shall be
made by the Borrowers to the Agent for the ratable benefit of the Banks in their
respective Proportionate Shares at the Agent's address specified in Section
10.10 hereof, in immediately available funds in coin or currency of the United
States of America. The Agent shall be entitled to charge any of the payments
owing to the Agent or any of the Banks hereunder or under any other Loan
Document to any account(s) of the Borrowers maintained at the Agent.

           (B) The Borrowers shall maintain a demand deposit account with the
Agent at all times that this Agreement is in effect, and the Agent may (and the
Borrowers authorize the Agent to) debit such deposit account of the Borrowers
(maintained with the Agent) for any amount due and owing as payment under the
Notes, hereunder or under any other Loan Document.

           (C) Unless the Agent shall have received notice from the Borrowers
prior to the date on which any payment is due to the Banks hereunder that the
Borrowers will not make such payment in full, the Agent may assume that the
Borrowers have made such payment in full to the Agent on such date and the Agent
may, in reliance upon such assumption, but shall be under no obligation to,
cause to be distributed to each Bank on such date an amount equal to the amount
then due such Bank.  If and to the extent that the Borrowers shall not have so
made such payment in full to the Agent, each Bank shall repay to the Agent
forthwith on demand such amount distributed to such Bank together with interest
thereon at the Federal Funds Rate, for

                                      54
<PAGE>

each day from the date such amount is distributed to such Bank until such Bank
repays such amount to the Agent.

          (D) The Agent shall after receipt of any payment (including any
repayment) relating to the payment of principal, interest, Letter of Credit
Outstandings, Commitment Fees or any other amounts due with respect to the
Obligations governed hereby, cause to be distributed in like funds to each Bank
such Bank's Proportionate Share of such payment, such distribution to be made by
the Agent (i) by 2:00 p.m. on the day such payment is made with respect to
payments received on or before 11:00 a.m. on such date and (ii) on the next
Business Day with respect to payments received after 11:00 a.m. on such date.
Such payments shall be made at the office of the appropriate Bank specified by
such Bank or at such other place as such Bank may from time to time designate in
writing to the Agent.  All payments on each Note shall be applied first to the
payment of interest then due on the unpaid amount thereof, and thereafter to the
payment and reduction of the unpaid principal amount thereof.  In the event the
Agent does not make timely payment as required hereby to any Bank, the Agent
shall pay interest to such Bank at the Federal Funds Rate on such unpaid amount
for each day such amount is unpaid until such amount is so paid to such Bank.

          (E) In the event any Bank shall obtain any payment (whether voluntary,
involuntary, through the exercise of any right of set-off, or otherwise) on
account of any amounts owing to it in excess of its ratable share of payments on
account of the Credit Facilities obtained by all the Banks, such Bank shall
forthwith purchase from the other Banks such participations in their respective
Proportionate Shares of the Credit Facilities owing to them as shall be
necessary to cause such purchasing Bank to share the excess payment ratably with
each of them; provided,

                                      55
<PAGE>

however, that if all or any portion of such excess payment is thereafter
recovered from such purchasing Bank, such purchase from each Bank shall be
rescinded and such Bank shall repay to the purchasing Bank the purchase price to
the extent of such recovery together with an amount equal to such Bank's ratable
share (according to the proportion of (a) the amount of such Bank's required
payment to (b) the total amount so recovered from the purchasing Bank) of any
interest or other amount paid or payable by the purchasing Bank in respect of
the total amount so recovered. The Borrowers agree that any Bank so purchasing a
participation from another Bank pursuant hereto, to the fullest extent permitted
by law and as provided herein, may exercise all its rights of payment (including
the right of set-off) with respect to such participation as fully as if such
Bank were the direct creditor of the Borrowers in the amount of such
participation.

     2.9.  DEFAULT RATE
           ------------

     From and after the occurrence and during the continuance of an Event of
Default, all principal amounts outstanding under the Credit Facilities shall
thereafter bear interest, payable on demand, at the Default Rate.  It is
expressly acknowledged and agreed by the Borrowers that the Default Rate is
intended to compensate the Banks for costs and losses associated with Events of
Default and is not a penalty.

     2.10. USE OF PROCEEDS

     2.11. FUNDING BY THE BANKS
           -------------------

           Non-Funding by a Bank.  In the event a Bank determines for any reason
           ---------------------                                               
not to make all or a portion of its Proportionate Share of any Revolving Credit
Advance available when requested, such Bank, not later than the close of
business on the date of such borrowing, shall notify the Agent of such
determination and the reasons therefor.  The foregoing shall not be construed to
relieve any Bank of its obligation to make any Revolving Credit Advance in
accordance with and subject to the terms and conditions of this Agreement.
Unless the Agent shall have been so notified by the non-funding Bank, the Agent
may assume that such Bank has made its Proportionate Share of such Revolving
Credit Advance available to the Agent in accordance with Section 2.1(C) hereof
and the Agent may, in reliance upon such assumption, make available to the
Borrowers on the date requested for such Revolving Credit Advance a
corresponding amount.  If and to the extent that a Bank, without so notifying
the Agent, shall not have made its Proportionate Share of a Revolving Credit
Advance available to the Agent, such Bank and the Borrowers agree to pay or
repay respectively to the Agent forthwith on demand such corresponding amount
together with interest thereon at the Federal Funds Rate, for each day from the
date of such Revolving Credit Advance until such amount is paid or repaid to the
Agent; provided, however, that in no event shall the Agent be entitled to
recover more than such corresponding amount plus interest as described above.
If such Bank shall pay to the Agent such corresponding amount, such amount so
paid shall constitute such Bank's Proportionate Share of such Revolving Credit
Advance for the purposes of this Agreement.  The Agent shall provide notice to
the Banks of a failure to fund by any Bank.

     2.13.  CONDITIONS TO ALL REVOLVING CREDIT ADVANCES AND ISSUANCES OF LETTERS
            --------------------------------------------------------------------
            OF CREDIT
            ---------

            The obligation of any Bank to make any Revolving Credit Advance or
of any Issuing Bank to issue any Letter of Credit is subject to fulfillment of
the following additional conditions precedent, to the reasonable satisfaction of
the Banks and their counsel:

               (A) Representations and Warranties.  The representations and
                   ------------------------------                         
warranties made by the Borrowers herein and in each of the other Loan Documents
or which are contained in any certificate, document or financial or other
statement furnished at any time under or in connection herewith shall be correct
in all material respects on and as of the date of such Revolving Credit Advance
or issuance of such Letter of Credit, after giving effect to such Revolving
Credit Advance or issuance of such Letter of Credit, as if made on and as of
such date, except for (i) those representations and warranties which speak
exclusively to a certain earlier date and (ii) changes in those representations
and warranties resulting from changes in circumstances after the date hereof
which do not violate this Agreement.

               (B) No Default.  No Event of Default or Default has arisen and is
                   ----------                                                  
continuing on the date such Revolving Credit Advance or issuance of such Letter
of Credit is to be made, after giving effect to such Revolving Credit Advance or
issuance of such Letter of Credit.

               (C) Litigation.  No suit, action, investigation, inquiry or other
                   ----------                                                  
proceeding by any governmental authority or other Person or any other legal or
administrative proceeding shall be pending or threatened which (i) questions the
validity or legality of the transactions contemplated by this Agreement or any
other Loan Document, or (ii) seeks damages

                                      62
<PAGE>

in connection therewith and which, in the reasonable judgment of the Agent or
the Required Banks, (x) involves a significant risk of a preliminary or
permanent injunction or other order by a state or federal court which would
prevent, or require rescission of, the transactions contemplated by this
Agreement, or (y) in the case of any action or proceeding which seeks monetary
damages involves a significant risk of resulting in substantial financial
liability to any of the Borrowers and/or the Agent or any of the Banks.

               (D) Material Adverse Change. No event shall have occurred since
                   -----------------------
the date of the most recent financial statements of Borrowers furnished to the
Banks which resulted in a Material Adverse Change of any Borrower or had a
Material Adverse Effect on any Borrower.

               (E) Revolving Credit Advances for Permitted Acquisitions.  As to
                   ----------------------------------------------------       
Revolving Credit Advances being used to finance (in whole or in part) Permitted
Acquisitions, the Agent shall have received such amendments to or additional
Loan Documents as may be necessary to cause (i) the acquired entity to become a
party to this Agreement and the other Loan Documents, (ii) the assets of the
acquired entity (including shares of stock in all domestic entities and 65% of
shares of stock of foreign entities) to become subject to the lien of the Agent
(for the ratable benefit of the Banks) and (iii) there to be delivered to the
Agent and the Banks such opinions of counsel, certificates and other documents
as reasonably requested by the Agent and the Banks.

               (E) Legal Matters. All legal matters incident to the making of
                   -------------

     2.14.  REGULATORY CAPITAL REQUIREMENTS
            -------------------------------

            If any law or regulation or the interpretation thereof by any court
or administrative or governmental authority charged with the administration
thereof enacted or made after the date hereof, or compliance by the Agent or any
of the Banks with any request or directive (whether or not having the force of
law) of any such authority issued after the date hereof, results in any
increases after the date hereof in any capital maintenance, capital ratio or
similar requirement against loan commitments made by any of the Banks and the
result thereof is to impose upon the Agent or any of the Banks or increase any
capital requirement applicable to any of the Banks as a result of the making or
maintenance of the revolving credit facility available or letters of credit
hereunder (which imposition of or increase in capital requirement may be
determined by such Bank's reasonable allocation of the aggregate of such capital
impositions or increases) then, upon demand by such Bank (which shall be made by
such Bank within 90 days of such Bank becoming aware of the circumstance which
gives rise to the demand), the Borrowers shall within ten (10) days of such
demand pay to such Bank from time to time as specified by such Bank an amount
which shall be sufficient to compensate such Bank for such imposition of or
increase in capital requirements together with interest on each such amount from
the date demanded until payment in full thereof at the Base Rate. A certificate
setting forth in reasonable detail the amount necessary to compensate such Bank
as a result of an imposition of or increase in capital requirements submitted by
such Bank to the Borrowers shall be conclusive, absent error or bad faith, as to
the amount thereof.

                                      64
<PAGE>

     2.15.  EXCESS REVOLVING CREDIT ADVANCES
            --------------------------------

            In the event the Agent on behalf of the Banks or any of the Banks
shall advance an amount in excess of the aggregate amount of all Revolving
Credit Advances and/or Letter of Credit Outstandings permitted under this
Agreement or if the Borrowers should directly or indirectly become indebted to
the Banks in an amount which, together with all Revolving Credit Advances and/or
Letter of Credit Outstandings pursuant to this Agreement, is in excess of the
aggregate amount permitted under this Agreement, such Revolving Credit Advances,
Letter of Credit Outstandings or such Indebtedness shall nevertheless be covered
by the terms of this Agreement and such excess shall be immediately paid by the
Borrowers to the Agent (for the account of the Banks).

     2.16.  REQUIREMENTS OF LAW
            -------------------

            If, after the date hereof, the adoption of or any change in any law,
regulation, treaty, or directive or any change in the interpretation or
application thereof or compliance by the Agent or any of the Banks with any
request or directive (whether or not having the force of law) from any central
bank or other governmental authority, agency or instrumentality:

            (A) does or shall subject the Agent or any of the Banks to any tax
imposed by the United States or any State or municipality thereof of any kind
whatsoever (except for taxes on income, net profits and/or gross receipts of the
Agent or any Bank) with respect to this Agreement, any Revolving Credit
Advances, the Term Loans or the Letters of Credit (or participations therein),
or change the basis of taxation of payments to the Agent or any of the Banks of
principal, commitment fee, interest or any other amount payable hereunder
(except for changes in the rate of any income tax presently imposed on the Agent
or any of the Banks); or

                                      65
<PAGE>

           (B) does or shall impose, modify, or hold applicable any reserve,
special deposit, compulsory loan or similar requirement against assets held by,
or deposits or other liabilities in or for the account of, advances or loans by,
or other credit extended by, or any other acquisition of funds by, any office of
the Agent or any of the Banks which are not otherwise included in the
determination of the Adjusted LIBOR Rate or the issuance of Letters of Credit
(or participations therein); or

           (C) has or would have the effect of reducing the rate of return on
any of the Banks' capital as a consequence of its obligations hereunder to a
level below that which such Bank reasonably could have achieved but for such
adoption, change or compliance (taking into consideration such Bank's policies
with respect to capital adequacy); or

           (D) does or shall impose on the Agent or any of the Banks any other
condition;

           and the result of any of the foregoing is to increase the cost to the
Agent or any of the Banks of making, renewing or maintaining (or participating
in) advances or extensions of credit to the Borrowers or to reduce any amount
receivable from the Borrowers hereunder or to reduce the rate of return on any
of the Banks' capital, then, in any such case, the Borrowers shall promptly pay
to such Bank, upon its demand (and delivery of the certificate referred to in
the last sentence of this paragraph), any additional amounts necessary to
compensate such Bank for such additional cost or reduced amount receivable or
reduced rate of return which such Bank deems to be material, as reasonably
determined by such Bank, with respect to this Agreement, any Revolving Credit
Advances, the Term Loans or the Letters of Credit (or participations therein).
If a Bank becomes entitled to claim any additional amounts pursuant to this
Section 2.16, it shall promptly notify the Borrowers (but in any event within 90
days of such Bank's becoming aware of its claim), the Agent and the other Banks
of the event by reason of which it has become so entitled.  A certificate
setting forth calculations as to any additional amounts payable pursuant to the
foregoing sentence submitted by a Bank to the Borrowers shall be conclusive in
the absence of error.  In the event a Bank which has received payment from the
Borrowers of amounts pursuant to this Section

                                      66
<PAGE>

2.16 obtains a refund from the governmental authority imposing the tax or other
charge which resulted in the required payment by the Borrowers hereunder, such
Bank shall pay to the Borrowers the amount so refunded up to the amount paid to
such Bank by the Borrowers.

     2.17.  ADJUSTED LIBOR RATE LOANS DECLARED UNLAWFUL.
            -------------------------------------------

     Notwithstanding any other provision of this Agreement, if the introduction
of or any change in or in the interpretation of any law or regulation by any
United States central bank or other United States governmental authority (either
federal, state or local) charged with the administration or interpretation
thereof shall make it unlawful, or any United States central bank or other
United States governmental authority (either federal, state or local) shall
assert that it is unlawful, for any Bank to perform its obligations hereunder
(i) to make or convert into Adjusted LIBOR Rate Loans or (ii) to continue to
fund or maintain Adjusted LIBOR Rate Loans hereunder, then, on notice thereof
and demand therefor by the Agent and/or any Bank to the Borrowers, the
obligation of such Bank or Banks to make any such Adjusted

                                      67
<PAGE>

LIBOR Rate Loans shall terminate and, if the foregoing clause (ii) is
applicable, the Borrowers shall, upon prior notice to the Agent, either (A)
forthwith repay in full any such Adjusted LIBOR Rate Loans then outstanding,
together with interest accrued thereon, or (B) forthwith convert any such
Adjusted LIBOR Rate Loans then outstanding into Base Rate Loans. If no such
notice is received by the Agent within three (3) Business Days of the prior
demand by the Agent for any Bank or Banks, the Borrowers will be deemed to have
made the election to convert any such Adjusted LIBOR Rate Loans then outstanding
into Base Rate Loans as of the fourth Business Day following such demand (or
earlier if circumstances so require). Any repayment or conversion of Adjusted
LIBOR Rate Loans as a result of the provisions of this Section 2.17 shall not
require payment of the Repayment Indemnity.

     2.18.  INABILITY TO ASCERTAIN INTEREST RATE FOR AN INTEREST PERIOD.
            ------------------------------------------------------------

     If, with respect to any Interest Period, the Agent reasonably determines
that (i) extraordinary circumstances affecting the relevant market make it
impracticable to ascertain the interest rate applicable for such Interest Period
or (ii) the Adjusted LIBOR Rate for such Interest Period will not adequately and
fairly reflect the cost to the Banks of making or maintaining the Adjusted LIBOR
Rate Loans during such Interest Period, the Agent shall promptly notify the
Borrowers of such determination and no additional Adjusted LIBOR Rate Loans
shall be made or continued nor shall there be any conversions thereto until such
notice is withdrawn (and such notice shall be promptly withdrawn after the
initial reasons for such notice are no longer applicable). If any Adjusted LIBOR
Rate Loans are outstanding on the date of such notice and such notice has not
been withdrawn on the last day of the then current Interest Period applicable
thereto, the Borrowers may on the last day of such Interest Period either
convert such Adjusted LIBOR Rate Loans to a Base Rate Loan or prepay the
outstanding principal balance thereof and accrued interest thereon in full. If
no notice is received by the Agent at least one (1) Business

                                      68
<PAGE>

Day prior to the last day of such Interest Period, the Borrowers will be deemed
to have made the election to convert any such Adjusted LIBOR Rate Loans then
outstanding into Base Rate Loans.

     2.19. SALE, ASSIGNMENT OR PARTICIPATIONS
           ----------------------------------

          (a) Any Bank may, with the consent of the Borrowers provided there is
not then any continuing Default or Event of Default (which consent shall not be
unreasonably withheld or delayed), assign to one or more assignees all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Commitments and the Revolving Credit Advances, the Letter of
Credit Outstandings (or participations therein) and the Term Loans at the time
owing to it); provided that (i) except in the case of an assignment to a Bank or
              --------                                                         
an Affiliate of a Bank, the Agent must give its prior written consent to such
assignment (which consent shall not be unreasonably withheld), (ii) except in
the case of an assignment to a Bank or an Affiliate of a Bank, the amount of
such assignment shall be a multiple of $3,000,000 and the amount of the
Commitments of the assigning Bank subject to each such assignment shall not be
less than $3,000,000 or such lesser amount as is then outstanding (unless a
Default or an Event of Default shall then be continuing, in which event there
shall be no such minimum), in each case determined as of the date an assignment
and assumption (an "Assignment and Assumption") with respect to such assignment
is delivered to the Agent, unless each of the Borrowers and the Agent otherwise
consent, (iii) each partial assignment shall be made as an assignment of a
proportionate part of all the assigning Bank's rights and obligations under this
Agreement, (iv) the parties to each assignment shall execute and deliver to the
Agent an Assignment and Assumption (in the form attached hereto as EXHIBIT I),
together with a processing and

                                      69
<PAGE>

recordation fee of $2,500, and (v) the assignee must be an Eligible Transferee.
At the time of each assignment pursuant to this Section 2.19(a) to a Person
which is not already a Bank hereunder and which is not a United States person
(as such term is defined in Section 7701(a)(30) of the Internal Revenue Code)
for Federal income tax purposes, the respective assignee Bank shall, to the
extent legally entitled to do so, provide to the Borrowers the appropriate
Internal Revenue Service Forms and, if applicable, a Section 2.20(b) Certificate
described in Section 2.20(b) hereof. Upon acceptance and recording pursuant to
paragraph (c) of this Section 2.19, from and after the effective date specified
in each Assignment and Assumption, the assignee thereunder shall be a party
hereto and, to the extent of the interest assigned by such Assignment and
Assumption, have the rights and obligations of a Bank under this Agreement (and
the Proportionate Shares of all Banks (including the assignee Bank) shall
automatically be deemed adjusted accordingly), and the assigning Bank thereunder
shall, to the extent of the interest assigned by such Assignment and Assumption,
be released from its obligations under this Agreement (and, in the case of an
Assignment and Assumption covering all of the assigning Bank's rights and
obligations under this Agreement, such Bank shall cease to be a party hereto but

10.15 hereof). Any assignment or transfer by a Bank of rights or obligations

in such rights and obligations in accordance with paragraph (d) of this Section
2.19.

register for the recordation of the names and addresses of the Banks, and the
Commitments of, and principal amount of the Revolving Credit Advances, Letter of

the Banks may treat each Person whose name is recorded in the Register pursuant
to the terms hereof as a Bank hereunder for all purposes of this Agreement
notwithstanding notice to the contrary. The Register shall be available for
inspection by the Borrowers and any Bank, at any reasonable time and from time
to time upon reasonable prior notice.
         
          (c) Upon its receipt of a duly completed Assignment and Assumption
executed by an assigning Bank and assignee, the processing and recordation fee
referred to in paragraph (a) of this Section 2.19 and any written consent to
such assignment required by paragraph (a) of this Section 2.19, the Agent shall
accept such Assignment and Assumption, record the information contained therein

entities (a "Participant") in all or a portion of such Bank's rights and
obligations under this Agreement (including all or a portion of its Commitments
and the Revolving Credit Advances, Letter of Credit Outstandings (or
participations therein) and Term Loans owing to it); provided that (i) such
                                                     --------             
Bank's obligations under this Agreement shall remain unchanged, (ii) such Bank
shall remain solely responsible to the other parties hereto for the performance
of such obligations and (iii) the Borrowers, the Agent, and the other Banks
shall continue to deal solely and directly with

                                      71
<PAGE>

such Bank in connection with such Bank's rights and obligations under this
Agreement. Any agreement or instrument pursuant to which a Bank sells such a
participation shall provide that such Bank shall retain the sole right to
enforce this Agreement and to approve any amendment, modification or waiver of
any provision of this Agreement; provided that such agreement or instrument may
                                 -------- 
provide that such Bank will not, without the consent of such Participant, agree
to any amendment, modification or waiver described in Section 10.2 hereof that
affects such Participant. The Borrowers agree that each Participant shall be
entitled to the benefits of Sections 2.14, 2.16, 2.20 and 10.15 hereof to the
same extent as if it were a Bank and had acquired its interest by assignment
pursuant to paragraph (a) of this Section 2.19.

          (e) Notwithstanding the foregoing and without the consent of the
Borrowers, any Bank may at any time pledge or assign or grant a security
interest in all or any portion of its rights under this Agreement to secure
obligations of such Bank, including any such pledge or assignment or grant to a
Federal Reserve Bank, and this Section 2.19 shall not apply to any such pledge
or assignment or grant of a security interest; provided that no such pledge or
                                               --------                      
assignment or grant of a security interest shall release a Bank from any of its
obligations hereunder or substitute any such assignee for such Bank as a party

will be made without setoff, counterclaim or other defense. Except as provided
in Section 2.20(b) hereof, all such payments will be made free and clear of, and
without deduction or withholding

                                      72
<PAGE>

for, any present or future taxes, levies, imposts, duties, fees, assessments or
other charges of whatever nature now or hereafter imposed by any jurisdiction or
by any political subdivision or taxing authority thereof or therein with respect
to such payments (but excluding, except as provided in the second succeeding
sentence, any tax imposed on or measured by the net income, net profits or gross
receipts of a Bank and any taxes imposed solely on deposits or net assets of a
Bank), and all interest, penalties or similar liabilities with respect to such
non-excluded taxes, levies, imposts, duties, fees, assessments or other charges
(all such non-excluded taxes, levies, imposts, duties, fees, assessments or
other charges being referred to collectively as "Non-Excluded Taxes"). Except as
otherwise provided in Section 2.20(b) hereof, if any Non-Excluded Taxes are so
levied or imposed, the Borrowers agree to pay the full amount of such Non-
Excluded Taxes and such additional amounts as may be necessary so that every
payment of all amounts due under this Agreement or under any Note, after
withholding or deduction for or on account of any Non-Excluded Taxes, will not
be less than the amount provided for herein or in such Note. If any amounts are
payable in respect of Non-Excluded Taxes pursuant to the preceding sentence, the
Borrowers agree to reimburse each Bank, upon the written request of such Bank,
for taxes imposed on or measured by the net income, net profits or gross
receipts of such Bank and for any withholding of taxes as such Bank shall
determine are payable by, or withheld from, such Bank, in respect of such
amounts so paid to or on behalf of such Bank pursuant to the preceding sentence
and in respect of any amounts paid to or on behalf of such Bank pursuant to this
sentence. The Borrowers will furnish to the Agent within 45 days after the date
the payment of any Non-Excluded Taxes is due pursuant to applicable law
certified copies of tax receipts evidencing such payment by the borrowers. The
Borrowers agree to indemnify

                                      73
<PAGE>

and hold harmless each Bank against, and reimburse such Bank upon its written
request for, the amount of any Non-Excluded Taxes so levied or imposed and paid
by such Bank. The provisions hereof shall survive the final payment of the
Obligations.

          (b) Each Bank that is not a United States person (as such term is
defined in Section 7701(a)(30) of the Internal Revenue Code (the "Code")) for
U.S. Federal income tax purposes agrees to deliver to the Borrowers and the
Agent on or prior to the Closing Date, or in the case of a Bank that is an
assignee or transferee of an interest under this Agreement pursuant to Section
2.19 hereof (unless the respective Bank was already a Bank hereunder immediately
prior to such assignment or transfer), on the date of such assignment or
transfer to such Bank, (i) two accurate and complete original signed copies of
Internal Revenue Service Form 4224 or 1001 (or successor forms) certifying to
such Bank's entitlement to a complete exemption from United States withholding
tax with respect to payments to be made under this Agreement and under any Note,
or (ii) if the Bank is not a "bank" within the meaning of Section 881(c)(3)(A)
of the Code and cannot delivery either Internal Revenue Service Form 1001 or
4224 pursuant to clause (i) above, (x) a certificate substantially in the form
of EXHIBIT J (any such certificate, a "Section 2.20 Certificate") and (y) two
accurate and complete original signed copies of Internal Revenue Service Form W-
8 (or successor form) certifying to such Bank's entitlement to a complete
exemption from United States withholding tax with respect to payments of
interest to be made under this Agreement and under any Note. In addition, each
such Bank agrees that from time to time after the Closing Date, when a lapse in
time or change in circumstances renders the previous certification obsolete or
inaccurate in any material respect, it will, promptly upon request by the
Borrowers, deliver to the Borrowers and the Agent two new accurate and complete

                                      74
<PAGE>

original signed copies of Internal Revenue Service Form 4224 or 1001, or Form W-
8 and a Section 2.20 Certificate, as the case may be, and such other forms as
may be required in order to confirm or establish the entitlement of such Bank to
a continued exemption from or reduction in United States withholding tax with
respect to payments under this Agreement and any Note, or it shall immediately
notify the Borrowers and the Agent of its inability to deliver any such Form or
Section 2.20 Certificate, in which case such Bank shall not be required to
deliver any such Form or Section 2.20 Certificate pursuant to this Section 2.20.
Notwithstanding anything to the contrary contained in Section 2.20(a) hereof,
but subject to Section 2.20(a) hereof, (x) the Borrowers shall be entitled, to
the extent each is required to do so by law, to deduct or withhold income or
similar taxes imposed by the United States (or any political subdivision or
taxing authority thereof or therein) from interest, fees or other amounts
payable hereunder for the account of any Bank which it not a United States
person (as such term is defined in Section 7701(a)(30) of the Code) for U.S.
Federal income tax purposes to the extent that such Bank has not provided to the
Borrowers U.S. Internal Revenue Service Forms that establish a complete
exemption from such deduction or withholding and (y) the Borrowers shall not be
obligated pursuant to Section 2.20(a) hereof to gross-up payments to be made to
a Bank in respect of income or similar taxes imposed by the United States if (i)
such Bank has not provided to the Borrowers the Internal Revenue Service Forms
required to be provided to the Borrowers pursuant to this Section 2.20(b) or
(ii) in the case of a payment, other than interest, to a Bank described in
clause (ii) above, to the extent that such Forms do not establish a complete
exemption from withholding of such taxes.

(for the ratable benefit of the Banks), and in such amounts, with such
companies, and against such risks as may be reasonably acceptable to the Agent,
and deliver copies of the policies evidencing such insurance to the Banks.  If
the Borrowers fail to take the action called for herein, the Agent, may, in its
discretion obtain insurance covering the Agent's (for the ratable benefit of the
Banks') interest in the Collateral and the amount of the premium for said
insurance shall be added to the Obligations of the Borrowers to the Agent and

<PAGE>

(and agents-in-fact) for the purpose of making, settling and adjusting claims
under such policies of insurance, endorsing the names of the Borrowers on any
check, draft, instrument or other item of payment for the proceeds of such
policies of insurance and for making all determinations and decisions with
respect to such policies of insurance. In the event the Borrowers, at any time
or times hereafter, shall fail to obtain or maintain any of the policies of
insurance required above or to pay any premium in whole or in part relating
thereto, then the Agent, without waiving or releasing any obligation or default
by the Borrowers hereunder, may (but shall be under no obligation to do so) at

in such amounts as companies similarly situated as the Borrowers would maintain
and to furnish to the Agent and the Banks from time to time evidence that such
insurance is in full force and effect.

OBLIGATIONS

                                   THE AGENT
                                   ---------

           The Banks by their execution of this Agreement or any acknowledgement
hereto hereafter executed by any Bank not a party hereto as of the date hereof,
hereby agree among themselves (and the Borrowers by their execution hereof
hereby acknowledge such agreement) as follows:

     9.1.  APPOINTMENT.
           -----------

           Each Bank by its execution of this Agreement or any subsequent
separate acknowledgment hereof, hereby appoints The Chase Manhattan Bank, as the
Agent hereunder and under the other Loan Documents, and agrees that The Chase
Manhattan Bank is authorized to act as its agent hereunder and under the other
Loan Documents to the extent provided in this Agreement and the other Loan
Documents. In addition, each Bank entering into any Interest Rate Protection
Agreement with the Borrowers in connection with the Credit Facilities and the
other Banks acknowledges and agrees that the security interest granted to the
Agent hereunder and in any other Loan Document in the Collateral secures the
Obligations under such Interest Rate Protection Agreement to such Bank on a
pari passu basis with the other Obligations of the Borrowers to the Banks in
---- -----
respect of the Credit Facilities. In the event the Agent after acceleration of
the Credit Facilities realizes upon Collateral or otherwise receives funds or
property in respect of the Obligations and at such a time there are Obligations
outstanding under any such Interest Rate Protection Agreement with any Bank (a
"Hedge Obligation"), the Proportionate Share of each Bank shall be adjusted
accordingly to take into account such Bank's Hedge Obligation so as to assure
that such Hedge Obligation is treated on a pari passu basis with
                                           ---- -----

                                      118
<PAGE>

all other Obligations of the Borrowers to the Banks in respect of the Credit
Facilities. In the event the Proportionate Shares of the Banks are adjusted as a
result of an outstanding Hedge Obligation to any Bank, and such Hedge
Obligations does become payable to such Bank, any Bank which received amounts in
excess of its Proportionate Share (calculated without taking into account such
Hedge Obligation) shall repay such excess to the other Banks in their
Proportionate Shares (calculated without taking into account such Hedge
Obligation). The Chase Manhattan Bank agrees to act as the Agent upon the
express conditions contained in this Article IX. The provisions of this Article
IX are solely for the benefit of the Agent, and neither the Borrowers nor any
other Person (other than the Banks) shall have any rights as a third party
beneficiary of any of the provisions of this Article IX. The Agent may perform
any of its duties hereunder by or through its agents or employees. For such
duties the Agent alone shall be entitled to the Agency Fee.

     9.2.  NATURE OF DUTIES.
           ----------------

           (a) The Agent shall have no duties or responsibilities except those
expressly set forth in this Agreement or the other Loan Documents. Neither the
Agent nor any of its officers, directors, employees or agents shall be liable
for any action taken or omitted to be taken by it as such hereunder or under any
other Loan Documents or in connection herewith or therewith, unless caused by
its or their gross negligence or willful misconduct. The duties of the Agent
shall be mechanical and administrative in nature; the Agent shall not have, by
reason of this Agreement or any other Loan Documents, a fiduciary relationship
in respect of any Bank; and nothing in this Agreement or any other Loan
Document, expressed or implied, is intended to or

                                      119
<PAGE>

shall be so construed as to impose upon the Agent any obligations in respect of
this Agreement or any other Loan Document except as expressly set forth herein.

           (b) The Agent's duties under this Agreement shall include the
following:
               (i)   The Agent shall maintain records relating to the available
amount of the Revolving Credit Facility and advise the Banks with respect to
such availability.

               (ii)  If the Agent obtains actual knowledge of any breach of
covenant or default by the Borrowers under this Agreement or any other Loan
Documents or of any fact or circumstance which, except for any grace period
permitted by this Agreement or such other Loan Document, as the case may be,
would result in any breach of covenant or default by the Borrowers hereunder or
under any other Loan Document, the Agent shall promptly report (to the extent
the officer obtaining such knowledge knows of the obligation to report same to
the Banks) such breach, default or information to the Banks.

               (iii) The Agent shall be responsible for coordinating any actions
among the Banks and between the Banks and the Borrowers.

               (iv)  The Agent shall act if and as directed by the Required
Banks subject to the terms and conditions herein.

     9.3.  LACK OF RELIANCE ON THE AGENT.
           -----------------------------

           Independently and without reliance upon the Agent, each Bank, to the
extent it deems appropriate, has made and shall continue to make (a) its own
independent investigation of the financial condition and affairs of the
Borrowers in connection with the making and

                                      120
<PAGE>

continuance of the Credit Facilities hereunder and the taking or not taking of
any action in connection herewith, and (b) its own appraisal of the
creditworthiness of the Borrowers, and except as expressly provided in this
Agreement, the Agent shall have no duty or responsibility, either initially or
on a continuing basis, to provide any Bank with any credit or other information
with respect thereto, whether coming into its possession before the making of
the Credit Facilities, or at any time or times thereafter. The Agent shall not
be responsible to any Bank for any recitals, statements, information,
representations or warranties herein or in any document, certificate or other
writing delivered in connection herewith, or for the execution, effectiveness,
genuineness, validity, enforceability, perfection, collectibility, priority or
sufficiency of this Agreement or any other Loan Document, or for the financial
condition of the Borrowers, nor shall the Agent 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 other Loan Document, or the financial
condition of the Borrowers, or the existence or possible existence of any Event
of Default.

     9.4.  CERTAIN RIGHTS OF THE AGENT.
           ---------------------------

           (a) If the Agent shall request instructions from the Banks or such
number of Banks required to so instruct the Agent with respect to any act or
action (including failure to act) in connection with this Agreement or any other
Loan Document, the Agent shall be entitled to refrain from such act or taking
such action unless and until the Agent shall have received instructions from the
Banks or such number of Banks required to so instruct the Agent, and the Agent
shall not incur liability to any Person by reason of so refraining. The Agent
shall be fully justified in failing or refusing to take any action hereunder or
under any other Loan Document (i)

                                      121
<PAGE>

if such action would, in the opinion of the Agent, be contrary to law or the
terms of this Agreement or the other Loan Documents or (ii) if it shall not
first be indemnified to its satisfaction by the Banks against any and all
liability and expense which may be incurred by it by reason of taking or
continuing to take any such action. Without limiting the foregoing, no Bank
shall have the right of action whatsoever against the Agent as a result of the
Agent acting or refraining from acting hereunder or under any other Loan
Documents in accordance with the instructions of the Banks or such number of
Banks required to so instruct the Agent.

           (b) The Agent shall be entitled to rely upon any written notice,
statement, certificate, order or other document or any telephone message
believed by it 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 other Loan Documents and its duties hereunder or thereunder,
upon advice of counsel reasonably selected by it.

     9.5.  INDEMNIFICATION.
           ---------------

           To the extent the Agent is not reimbursed and indemnified by the
Borrowers, the Banks will reimburse and indemnify the Agent, in proportion to
their Proportionate Share of the Revolving Credit Facility, for and against any
and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, attorneys' fees and expenses, costs, expenses or disbursements
of any kind or nature whatsoever which may be imposed on, incurred by or
asserted against the Agent in performing its duties hereunder or under any other
Loan Document, in any way relating to or arising out of this Agreement or any
other Loan Document; provided that no Bank shall be liable for any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting from the Agent's

                                      122
<PAGE>

gross negligence or willful misconduct. The provisions hereof shall survive the
final repayment of the Obligations.

     9.6.  THE AGENT IN ITS INDIVIDUAL CAPACITY.
           ------------------------------------

           With respect to its obligation to extend credit under the Credit
Facilities as a Bank under this Agreement, Chase shall have the rights and
powers specified herein for a Bank and may exercise the same rights and powers
as though it were not performing the duties of the Agent specified herein, may
lend money to and generally engage in any kind of lending business with the
Borrowers, or any Subsidiary or Affiliate of the Borrowers, as if it were not
performing the duties specified herein, may accept fees and other consideration
from the Borrowers for services in connection with this Agreement and otherwise
without having to account for the same to the other Banks and the terms "Banks,"
or any similar terms shall, unless the context clearly otherwise indicates,
include Chase in its individual capacity.

     9.7.  HOLDERS.
           -------

           The Agent may deem and treat the payee of any Note as the owner
thereof for all purposes hereof unless and until a written notice of the
assignment, transfer or endorsement thereof, as the case may be, shall have been
filed with the Agent. Any request, authority or consent of any Person or entity
who, at the time of making such request or giving such authority or consent, is
the holder of any Note shall be conclusive and binding on any subsequent holder,
transferee, assignee or endorsee, as the case may be, of such Note issued in
exchange thereof.

     9.8.  SUCCESSOR AGENTS.
           ----------------

           (a) The Agent may resign from the performance of all its functions
and duties as Agent hereunder and/or under the other Loan Documents at any time
by giving thirty (30)

                                      123

appoint a successor Agent who shall be a Bank hereunder.

then appoint a successor Agent who shall serve as Agent hereunder or thereunder
until such time, if any, as the Required Banks appoint a successor Agent as
provided above.

               (d) If no successor Agent has been appointed pursuant to clause
(b) or (c) by the thirty-fifth (35th) Business Day after the date on which such
notice of resignation was given, the Agent's resignation shall become effective

hereof or thereof, or preclude any other or further exercise thereof, or

grant of security interests in and Liens on the Collateral as set forth in

indefeasibly paid in full and any commitment to extend credit has been
terminated.

     10.14.  INTEREST LIMITATION
             -------------------

             It is the intention of the Agent and the Banks and the Borrowers to
conform strictly to the laws of the State of New Jersey or the laws of such
other jurisdiction which may be found to apply to the subject transaction
relating to the maximum rate of interest which may be lawfully contracted for or
charged. Nothing contained in this Agreement or any other Loan Document shall be
construed to mean that the Borrowers have contracted to pay or are obligated to
pay any sum or sums to the Agent and/or the Banks in excess of those which may
lawfully be

                                      130
<PAGE>

charged or contracted for under applicable law of the State of New Jersey or
other applicable law. If any provision of this Agreement or any of the other
Loan Documents shall require payment of any sum or sums of interest in excess of
the maximum permitted rate which may be lawfully contracted for or charged, then
the Borrowers, the Agent, and the Banks agree that such result is as a
consequence of their inadvertence and/or mistake, and the interest charge for
which the Borrowers are liable under this instrument shall be recomputed for the
sole and limited purpose of determining the extent of the obligations and
liabilities of the Borrowers to the Agent and/or the Banks so that the interest
charges for which the Borrowers are liable shall not exceed the maximum

effect to any recomputation and adjustment required pursuant to the foregoing
provisions of this Section, or if such outstanding principal balance and
interest are paid in full, any such excess shall be remitted by the Agent,
