              AMOUNT AND TERMS FOR THE REVOLVING CREDIT FACILITY
              --------------------------------------------------

     Section 2.01 Revolving Credit Facility.
                  -------------------------

          (i)  Availability.  (a)  Subject to the terms, conditions and
               ------------
provisions set forth in this Loan Agreement and provided no Event of Default or
Potential Event of Default shall have occurred and be continuing, the Lender
hereby agrees to make available to the Borrower from time to time during the
period from the Closing Date up through and including the Business Day next
preceding the Revolving Credit Termination Date, revolving credit loans
(hereinafter each individually referred to as a "Revolving Credit Loan" and
collectively referred to as the "Revolving Credit Loans") in amounts which shall
not exceed, in the aggregate for all Revolving Credit Loans at any time
outstanding, the Commitment.  The Revolving Credit Loans shall be evidenced by
the Revolving Credit Loan Note.  The Lender is hereby authorized to record the
date and amount of each Revolving Credit Loan made by the Lender and the date
and amount of each payment or prepayment of principal thereof made by the
Borrower on the Schedule "1" annexed to and constituting a part of the Revolving
                ------------
Credit Loan Note, and any such recordation shall constitute prima facie evidence
of the accuracy of the information so recorded.  If the outstanding amount of
the Revolving Credit Loans shall exceed the amount of the Revolving Credit
Facility at any time, such excess shall be immediately due and payable to the
Lender and subject to the terms, conditions and provisions of this Loan
Agreement.

               (b) Revolving Credit Loans may be voluntarily prepaid pursuant to
Section 2.04 hereof and, subject to the provisions of this Loan Agreement, any
------------
amounts so prepaid may be reborrowed, up to the amount available under this
Section 2.01(i) at the time of such Borrowing, until the Business Day next
---------------
preceding the Revolving Credit Termination Date.  The Lender's commitment to
make Revolving Credit Loans shall automatically expire, and each Revolving
Credit Loan then outstanding shall be repaid in full by the Borrower, no later
than the Revolving Credit Termination Date.

          (ii) Notice of Borrowing.  Whenever the Borrower desires to borrow
               -------------------
under this Section 2.01, the Borrower shall deliver to the Lender a Notice of

proposed Funding Date, in the case of a Borrowing as a Base Rate Loan, and (b)
11:00 A.M. (New York City, New York time) at least three (3) Business Days in
advance of the proposed Funding Date, in the case of a Borrowing as a Eurodollar
Rate Loan.  The Notice of Borrowing shall specify (1) the Funding Date (which
shall be a Business Day) in respect of the Revolving Credit Loan, (2) the amount
of the proposed Borrowing which shall not be less than (A) $250,000.00, in the

Borrowing as a Eurodollar Rate Loan, (3) the intended use of the proceeds of
such Borrowing, (4) the applicable interest rate option as described in Section
                                                                        -------
2.02(i) of this Loan Agreement and, if applicable, (5) the Eurodollar Interest
-------
Period for such Revolving Credit Loan.  In lieu of delivering the above-
described Notice of Borrowing, such Borrower may give the Lender telephonic
notice of any proposed Borrowing by the time required under this Section
                                                                 -------
2.01(ii); provided, however, that such notice shall be confirmed in writing by
--------  --------  -------
delivery to the Lender promptly (but in no event later than the Funding

                                       23
<PAGE>

Date of the requested Revolving Credit Loan) of a Notice of Borrowing. Any
Notice of Borrowing (or telephonic notice in lieu thereof) pursuant to this
Section 2.01(ii) shall be irrevocable.
----------------

          (iii)  Making of Revolving Credit Loans.  The Lender shall make the
                 --------------------------------
proceeds of such Revolving Credit Loan available to the Borrower in Newark, New
Jersey on such Funding Date by the end of business on such Funding Date and
shall disburse such funds in Dollars and in immediately available funds to an
account of the Borrower maintained with the Lender and thereafter to any
substitute account designated in writing by the Borrower in the Notice of
Borrowing.

          (iv)   Use of Proceeds of Revolving Credit Loans.  The proceeds of the
                 -----------------------------------------
Revolving Credit Loans shall be used by the Borrower for financing the general
corporate purposes of the Borrower including the financing of Permitted
Acquisitions (but expressly excluding the financing of the Stock Repurchase
                  -------------------
Program).

          (v)    Reduction of Revolving Credit Facility; Revolving Credit
                 --------------------------------------------------------
Termination Date.
----------------

                 (a)  The Borrower shall have the right, at any time and from
time to time, to terminate in whole or permanently reduce in part, the Revolving
Credit Facility in an amount up to the amount of the Commitment minus the
                                                                -----
aggregate principal amount of the Revolving Credit Loans then outstanding. Any
such prepayment may be made by the Borrower without premium or fee, except as
                                                                    ------
provided for in Section 2.04 of this Loan Agreement with respect to the
                ------------
prepayment of a Eurodollar Rate Loan.  The Borrower shall give not less than
three (3) Business Days' prior express written notice to the Lender designating
the date (which shall be a Business Day) of such termination or reduction and
the amount of any partial reduction.  Such termination or partial permanent
reduction of the Revolving Credit Facility and the Commitment shall be effective
on the date specified in the Borrower's notice.  Any such partial permanent
reduction of the Revolving Credit Facility shall be in an aggregate minimum
principal amount of $1,000,000.00 and integral multiples of $500,000.00 in
excess of that amount.

                 (b)  The Revolving Credit Facility shall automatically expire
without further action on the part of the Lender, and all then outstanding
Revolving Credit Loans shall be paid in full, on the Revolving Credit
Termination Date.

          (vi)   No Amortization of the Revolving Credit Facility.  Prior to the
                 ------------------------------------------------
Revolving Credit Termination Date, provided no Event of Default of Potential
Event of Default shall have occurred and be continuing, there shall be no
required scheduled principal amortization payments due and owing to the Lender
on the Revolving Credit Facility.  The full and final payment of any and all
principal, unpaid accrued interest, fees, costs and expenses, if any, owing to
the Lender under the Revolving Credit Facility shall be made by the Borrower to
the Lender on the Revolving Credit Termination Date.  The Lender hereby agrees
that no "annual clean-up" of the Revolving Credit Loan shall be required.

     Section 2.02 Interest on the Revolving Credit Facility.
                  -----------------------------------------

          (i)    Rates of Interest.  (a)  All Revolving Credit Loans shall bear
                 -----------------
interest

                                       24
<PAGE>

computed daily on the outstanding principal balance thereof from the Funding
Date thereof until repaid in full at one or more of the interest rate options
selected by the Borrower from between the two (2) interest rate options set
forth below. Subject to the provisions of this Loan Agreement, the Borrower may
select different options to apply simultaneously to different portions of the
Revolving Credit Loans and may select different Funding Segments to apply
simultaneously to different parts of the Eurodollar Portion of the Revolving
Credit Loans. Each selection of an interest rate option shall apply separately
and without overlap to the Revolving Credit Loans as a class. There shall be no
limit to the aggregate number of Funding Segments applicable to the Eurodollar
Portion of the Revolving Credit Loans at any time.

          Interest Rate Options for Revolving Credit Loans:
          ------------------------------------------------

               (1)  Eurodollar Rate Option.  A fluctuating rate per annum (fixed
                    ----------------------
     for each particular Eurodollar Interest Period only) for each day during a
                                                    ----
     Eurodollar Interest Period equal to (A) the Adjusted LIBO Rate plus (B) the
                                                                    ----
     Applicable Margin for such day.  The Lender shall give prompt notice to the
     Borrower of the Adjusted LIBO Rate, determined or adjusted in accordance
     with the provisions hereof, which determination or adjustment shall be
     conclusive (absent manifest error) if made by the Lender in good faith.
     The Adjusted LIBO Rate shall be calculated in accordance with the
     Eurodollar Reserve Percentage, if the Lender is required to hold such
     reserves; or

               (2)  Base Rate Option:  A fluctuating rate per annum for each day
                    ----------------
     equal to (A) the Base Rate of the Lender, in effect from time to time (such
     interest rate to change immediately upon any change in the Base Rate) plus
                                                                           ----
     (B)  the Applicable Margin for such day.

               (b)  The Applicable Margin for Eurodollar Rate Loans and Base
Rate Loans with respect to the Revolving Credit Loan Facility for any day shall
be the applicable amount (expressed in basis points) set forth in the Pricing
Grid (hereinafter referred to as the "Applicable Margin"). For purposes of this
Section 2.04(i)(b), the Consolidated Cash Flow Leverage Ratio shall be tested at
------------------
the end of the periods covered by the quarterly and annual consolidated
financial statements which are to be provided to the Agent pursuant to Section
                                                                       -------
5.02 of the Loan Agreement. Any change in the Applicable Margin (both increases
----
and decreases therein) shall be effective on the first (1/st/) day of the Fiscal
Quarter following the Fiscal Quarter in which the Lender is entitled to receive
said submitted financial statements for a prior Fiscal Quarter all as provided
for in Article V hereof. For example, for financial statements covering the
       ---------
first Fiscal Quarter of any Fiscal Year, the effective date of any increase or
decrease in the Applicable Margin would be July 1/st/ of said calendar year. For
the period from the Closing Date up through and including the date upon which
the Lender receives the September 30, 1999 Compliance Certificate attached to
the Officer's Certificate set forth on Exhibit "D" attached hereto and made a
                                       -----------
part hereof, the Applicable Margin for Base Rate Loans and Eurodollar Rate Loans
shall be the percentage described at Level I on the Pricing Grid. Thereafter,
the Applicable Margin for Base Rate Loans and Eurodollar Rate Loans shall be set
and established based upon the Consolidated Cash Flow Leverage Ratio tested in
accordance with the terms, conditions and provisions set forth in Section 8.02
                                                                  ------------
hereof.

               (c)  Notwithstanding subsections (a) and (b) above, interest in
                                    -----------------------
respect

                                       25
<PAGE>

of any Revolving Credit Loan shall not exceed the maximum rate permitted
by applicable Law.

          (ii)  Interest Payments.  Subject to the terms, conditions and
                -----------------
provisions of Section 2.02(iv) hereof, interest accrued on all Base Rate Loans
              ----------------
shall be payable by the Borrower in arrears (a) on the first Business Day of
each month during the term of this Loan Agreement, commencing on the first
Business Day of the first full month next following the making of each such Base
Rate Loan and (b) at maturity.  Interest accrued on each Eurodollar Rate Loan
shall be payable by the Borrower in arrears (1) on each Eurodollar Interest
Payment Date applicable to such Eurodollar Rate Loan, (2) upon prepayment
thereof in full or in part and (3) at maturity.

          (iii) Conversion or Continuation.  (a)  Subject to the terms,
                --------------------------
conditions and provisions of Section 2.06 hereof, the Borrower shall have the
                             ------------
option (1) to convert at any time all or any part of outstanding Revolving
Credit Loans which comprise part of the same Borrowing and which, in the
aggregate, equal $500,000.00 from Base Rate Loans to Eurodollar Rate Loans; (2)
to convert all or any part of outstanding Revolving Credit Loans from Eurodollar
Rate Loans to Base Rate Loans or (3) upon the expiration of any Eurodollar
Interest Period applicable to a Borrowing of Eurodollar Rate Loans, to continue
all or any portion of such Revolving Credit Loans equal to $500,000.00 as
Eurodollar Rate Loans of the same type, and the succeeding Eurodollar Interest
Period of such continued Revolving Credit Loans shall commence on the expiration
date of the Eurodollar Interest Period applicable thereto; provided, however,
                                                           --------  -------
that no outstanding Revolving Credit Loan may be continued as, or be converted
into, a Eurodollar Rate Loan when any Event of Default or Potential Event of
Default has occurred and is continuing.

                (b) In the event the Borrower shall elect to convert or continue
a Revolving Credit Loan under this Section 2.02 (iii), the Borrower shall
                                   ------------------
deliver a Notice of Conversion/Continuation to the Lender no later than 11:00
a.m. (New York City, New York time) at least three (3) Business Days in advance
of the proposed conversion/continuation date in the case of a conversion to or a
continuation of a Eurodollar Rate Loan. A Notice of Conversion/Continuation
shall specify (1) the proposed conversion/continuation date (which shall be a
Business Day), (2) the amount of the Revolving Credit Loan to be
converted/continued, (3) the nature of the proposed conversion/continuation, and
(4) in the case of a conversion to, or continuation of, a Eurodollar Rate Loan,
the requested Eurodollar Interest Period. In lieu of delivering the above-
described Notice of Conversion/Continuation, the Borrower may give the Lender
telephonic notice of any proposed conversion/continuation by the time required
under this Section 2.02(iii); provided, however, that such notice shall be
           -----------------  --------  -------
confirmed in writing by delivery to the Lender promptly (but in no event later
than the proposed conversion/continuation date) of a Notice of
Conversion/Continuation. In the event the Borrower shall fail to provide the
Lender with the requisite Notice of Conversion/Continuation for a continuation
of any Eurodollar Rate Loan within the time prescribed above, said Eurodollar
Rate Loan shall automatically continue as a Eurodollar Rate Loan for the same
Eurodollar Interest Period.

                (c) Any Notice of Conversion/Continuation for conversion to, or
continuation of, a Revolving Credit Loan (or telephonic notice in lieu thereof)
shall be irrevocable and the Borrower shall be bound to convert or continue in
accordance therewith.

                                       26
<PAGE>

          (iv)  Default Interest.  Notwithstanding the rate of interest
                ----------------
specified in Section 2.02(i) hereof and the payment dates specified in Section
             ---------------                                           -------
2.02(ii) and Section 2.05(i) hereof, effective immediately upon the occurrence
--------     ---------------
of any Event of Default and for as long thereafter as any such Event of Default
shall be continuing, the principal balance of all Revolving Credit Loans then
outstanding and any interest payments on the Revolving Credit Loans not paid
when due shall bear interest, to the extent permitted by applicable Law, payable
upon demand at the Default Rate. The Borrower hereby acknowledges that: (a) such
Default Rate is a material inducement to the Lender to make the Revolving Credit
Facility available to the Borrower; (b) the Lender would not have made the
Revolving Credit Facility available to the Borrower in the absence of the
agreement of the Borrower to pay such Default Rate; (c) such Default Rate
represents compensation for increased risk to the Lender that the Revolving
Credit Facility will not be repaid; and (d) such Default Rate is not a penalty
and represents a reasonable estimate of (1) the cost to the Lender in allocating
its resources (both personnel and financial) to the on-going review, monitoring,
administration and collection of the Revolving Credit Facility and (2)
compensation to the Lender for losses that are difficult to ascertain.

          (v)   Computation of Interest.  Interest on all Revolving Credit Loans
                -----------------------
shall be computed on the basis of the actual number of days elapsed in the
period during which interest accrues and a year of 360 days.  In computing
interest on any Revolving Credit Loan, the date of the making of the Revolving
Credit Loan or the first day of a Eurodollar Interest Period, as the case may
be, shall be included and the date of payment or the expiration date of a
Eurodollar Interest Period, as the case may be, shall be excluded; provided,
                                                                   --------
however, that if a Revolving Credit Loan is repaid on the same day on which it
-------
is made, one day's interest shall be paid on that Revolving Credit Loan.

          (vi) Changes: Legal Restrictions.  Except as provided in Section
               ---------------------------                         -------
2.06(iv) hereof with respect to certain determinations on Eurodollar Interest
--------
Rate Determination Dates, in the event that after the date hereof (a) the
adoption of or any change in any law, treaty, rule, regulation, guideline or
determination of a court or Governmental Authority or any change in the
interpretation or application thereof by a court or Governmental Authority or
(b) compliance by the Lender with any request or directive (whether or not
having the force of law and whether or not the failure to comply therewith would
be unlawful) from any central bank or other Governmental Authority or quasi-
governmental authority:

               (1)  does or may impose, modify, or hold applicable, in the
determination of a Lender, any reserve, special deposit, compulsory loan, FDIC
insurance, capital allocation or similar requirement against assets held by, or
deposits or other liabilities in or for the account of, advances or loans by,
commitments made, or other credit extended by, or any other acquisition of funds
by, the Lender or any applicable lending office or Eurodollar Affiliate of the
Lender (except, with respect to a Eurodollar Rate Loan, to the extent that the
Statutory Reserve Rate requirements are reflected in the definition of "Adjusted
LIBO Rate"); or

               (2)  does or is reasonably likely to impose on the Lender any
other condition materially more burdensome in nature, extent or consequence than
those in existence as of the Closing Date;

and the result of any of the foregoing is to increase the cost to the Lender of
making, renewing or

                                       27
<PAGE>

maintaining the Revolving Credit Loans, then, in any such case, the Borrower
shall promptly pay to the Lender, upon demand, such amount or amounts (based
upon an allocation thereof by the Lender to the financing transactions
contemplated by this Loan Agreement and effected by this Section 2.02(vi) as may
                                                         ---------------
be necessary to compensate the Lender for any such additional cost incurred or
reduced amount received. The Lender shall deliver to the Borrower a written
statement of the costs or reductions claimed and the basis therefore, and the
allocation made by the Lender of such costs and reductions shall be conclusive,
absent manifest error, if made in good faith. If the Lender subsequently
recovers any amount previously paid by the Borrower pursuant to this Section
                                                                     -------
2.02(vi), the Lender shall, within thirty (30) days after receipt of such refund
--------
and to the extent permitted by applicable Law, pay to the Borrower the amount of
any such recovery.

      Section 2.03  Fees.
                    ----

          (i)   Facility Fee.  The Borrower shall have paid to the Lender the

of one percent (0.125%) per annum multiplied by (b) the positive difference
                                  ---------- --
between (1) the average daily amount of the Commitment minus (2) the aggregate
                                                       -----
average daily amount of all Revolving Credit Loans outstanding under the
Revolving Credit Facility from time to time.  All such commitment fees payable
under this Section 2.03(ii) shall be calculated and payable quarterly in arrears
           ----------------
on the last Business Day in each Fiscal Quarter beginning after the Closing
Date.

          (iii) Late Charge Fee.  In the event that any payment (other than a
                ---------------
payment of principal and/or interest) required to be made by the Borrower under
the Revolving Credit Loan Note or under this Loan Agreement shall not be
received by the Lender within ten (10) days of when due, the Lender may charge,
and if so charged, the Borrower shall pay, a late charge of ($0.05) for each
dollar ($1.00) of each delinquent payment for the purpose of defraying the
expense incident to the handling of such delinquent payment.  In no event shall
said late charge fee be less than ten dollars ($10.00).

          (iv)  Payment of Fees. The fees described in this Section 2.03
                ---------------                             ------------
represent compensation for services rendered and to be rendered separate and
apart from the lending of money or the provision of credit, and the obligation
of the Borrower to pay each fee described herein shall be in addition to, and
not in lieu of, the obligation of the Borrower to pay interest, other fees and
expenses otherwise described in this Loan Agreement.  Fees shall be payable when
due at the office of the Lender in Newark, New Jersey in immediately available
funds.  All fees shall be non-refundable when paid.  All fees and expenses
specified or referred to in this Loan Agreement due and owing to the Lender,
including, without limitation, those referred to in this Section 2.03 and in
                                                         ------------

time to time, upon the giving of at least three (3) Business Days' prior express
written notice to the Lender, voluntarily prepay any Eurodollar Rate Loan in
whole or in part, in an aggregate minimum amount of $500,000.00, subject to the

          (ii)  Base Rate Loans.  The Borrower may, at any time and from time to
                ---------------
time, upon the giving of at least one (1) Business Day's prior express written
notice to the Lender, voluntarily prepay any Base Rate Loan in whole or in part,
in an aggregate minimum amount of $250,000.00, without premium or fee; provided,
                                                                       --------
however, any principal prepayment of a Base Rate Loan shall be accompanied by
-------
the payment of all unpaid accrued interest due and owing on said Base Rate Loan.

          (iii) Prepayments in Full.  Notwithstanding any term, condition or
                -------------------
provision of this Section 2.04 to the contrary, in the event that any
                  ------------
prepayments of any Revolving Credit Loans are made in connection with the
termination of this Loan Agreement, such prepayments shall be made only upon
three (3) Business Days' prior express written notice to the Lender.

     Section 2.05 Payments.
                  --------

          (i)  Manner and Time of Payment.  All payments of principal, interest
               --------------------------
and fees hereunder payable to the Lender, including, without limitation, all
payments in connection with Revolving Credit Loans, shall be made without
condition or reservation or right, in Dollars and in immediately available
funds, delivered to the Lender not later than 2:00 p.m. (New York City, New York
time) on the date due, to such account of the Lender in Newark, New Jersey, as
the Lender may designate.  Funds received by the Lender after that time and date
shall be deemed to have been paid on the next succeeding Business Day.  The
Lender shall send a monthly and/or quarterly invoice, as applicable, to the
Borrower reflecting the accrued interest due and owing and all fees due and
owing hereunder.  The Borrower hereby agrees that on the Business Day that any
payment of principal, interest and fees are due, the Borrower shall initiate the
transfer of such payment to the Lender; provided, however, if the Borrower shall
                                        --------  -------
fail to initiate such payment no later than the date on which any such payment
is due and owing to the Lender, the Lender shall, and is hereby authorized by
the Borrower to, automatically charge a demand deposit account of the Borrower,
which account shall be maintained with the Lender at all times throughout the
term of the Revolving Credit Facility.  The Borrower's authorization of the
Lender to charge such account having sufficient funds on deposit shall
constitute payment of the amount so authorized notwithstanding the Lender's
failure to charge said account.  Any failure or delay by the Lender in
submitting invoices for interest and fee payments shall not discharge or relieve
the Borrower of the obligation to make such payments into the demand deposit
account or

                                       29
<PAGE>

to initiate any such transfer of payment.

          (ii)  Apportionment of Payments.  So long as there does not exist an
                -------------------------
Event of Default, all payments of principal and interest in respect of
outstanding Revolving Credit Loans, all payments of the fees described herein
and all payments in respect of any other Obligation shall be allocated by the
Lender as it may be entitled thereto as provided herein.  After the occurrence
and during the continuance of an Event of Default, the Lender shall, after
providing notice to the Borrower that payments and proceeds shall be so applied,
apply all payments remitted to the Lender and all amounts received by the
Lender, subject to the provisions of this Loan Agreement, (a) first, to pay
Obligations in respect of any fees, expense reimbursements or indemnities then
due and owing to the Lender from the Borrower; (b) second, to pay interest due
in respect of Revolving Credit Loans and to pay (or to the extent such
Obligations are contingent, prepay or provide cash collateral in respect of);
(c) third, to pay or prepay principal of Revolving Credit Loans in the inverse
order of maturity and (d) fourth, to the ratable payment of all other
Obligations.

          (iii) Payments on Non-Business Days.  Whenever any payment to be made
                -----------------------------
by the Borrower hereunder shall be stated to be due on a day which is not a
Business Day, payments shall be made on the next succeeding Business Day and
such extension of time shall be included in the computation of the payment of
interest hereunder and of any of the fees specified in Section 2.03 hereof, as
                                                       ------------
the case may be.

          (iv)  Lender's Accounting.  The Lender shall maintain a loan account
                -------------------
(hereinafter referred to as the "Loan Account") on its books in which shall be
recorded (a) the principal amount of Revolving Credit Loans owing to the Lender
from time to time; (b) all other appropriate debits and credits as provided in
this Loan Agreement, including, without limitation, all interest, fees,
expenses, charges and other Obligations; and (c) all payments of Obligations
made by the Borrower or for the Borrower's account.  All entries in the Loan
Account shall be made in accordance with the Lender's customary accounting
practices as in effect from time to time.  The Lender will render a statement of
the Loan Account upon the request of the Borrower.  Each and every such
statement shall be deemed final, binding and conclusive upon the Borrower in all
respects as to all matters reflected therein (absent manifest error), unless the
Borrower, within fifteen (15) days after the date such statement is rendered,
delivers to the Lender written notice of any objection which the Borrower may
have to any such statement.  In that event, only those items expressly objected
to in such notice shall be deemed to be disputed by the Borrower.
Notwithstanding the foregoing, the Lender's entries in the Loan Account
evidencing Revolving Credit Loans and other financial accommodations made from
time to time shall be final, binding and conclusive upon the Borrower (absent
manifest error) as to the existence and amount of the Obligations recorded in
the Loan Account.  The Lender, in its discretion, may charge any or all
interest, fees and expenses incurred by the Borrower hereunder to the Loan
Account.

     Section 2.06 Special Provisions Governing Eurodollar Rate Loans.
                  --------------------------------------------------
Notwithstanding other provisions of this Loan Agreement to the contrary, if any,
the following provisions shall govern with respect to Eurodollar Rate Loans as
to the matters described below:

          (i)   Amount of Eurodollar Rate Loans. Each Eurodollar Rate Loan shall
                -------------------------------
be for a minimum amount of $500,000.00.

                                       30
<PAGE>

          (ii)  Determination of Eurodollar Interest Period. By giving notice as
                -------------------------------------------
set forth in Sections 2.01(ii) and 2.02(iii) hereof (with respect to a
             -------------------------------
conversion into or a continuation of Eurodollar Rate Loans), the Borrower shall
have the option, subject to the other terms, conditions and provisions of this
Section 2.06, to specify the Eurodollar Interest Period to apply to the
------------
Borrowing of Eurodollar Rate Loans described in such notice, subject to
availability. The determination of Eurodollar Interest Periods shall be subject
to the following provisions:

                (a) In the case of immediately successive Eurodollar Interest
Periods applicable to a Borrowing of Eurodollar Rate Loans, each successive
Eurodollar Interest Period shall commence on the day on which the next preceding
Eurodollar Interest Period expires;

                (b) If any Eurodollar Interest Period would otherwise expire on
a day which is not a Business Day, the Eurodollar Interest Period shall be
extended to expire on the next succeeding Business Day; provided, however, that
                                                        --------  -------
if any such Eurodollar Interest Period applicable to a Borrowing of Eurodollar
Rate Loans would otherwise expire on a day which is not a Business Day but is a
day of the month after which no further Business Day occurs in that month, then
that Eurodollar Interest Period shall expire on the immediately preceding
Business Day;

                (c) The Borrower may not select a Eurodollar Interest Period for
any Revolving Credit Loan which terminates later than the Revolving Credit
Termination Date;

                (d) The Borrower may not select a Eurodollar Interest Period
with respect to any portion of principal of a Eurodollar Rate Loan which extends
beyond a date on which the Borrower is required to make a scheduled payment of
any portion of principal, it being understood and agreed that any Eurodollar
Rate Loan whose Eurodollar Interest Period ends less than one month prior to
such required principal payment date shall be deemed converted to a Base Rate
Loan as of the last day of such Eurodollar Interest Period for purposes of
determining whether any portion of principal of any Eurodollar Rate Loan is
required in order to make a mandatory payment of principal;

                (e) There shall be no limit to the number of Eurodollar Interest
Periods under this Loan Agreement in effect at any one time under the Revolving
Credit Facility; and

                (f) If any Eurodollar Interest Period commences on the last
Business Day of a calendar month (or on a day for which there is no numerically
corresponding day in the last calendar month of such Eurodollar Interest Period)
then said Eurodollar Interest Period shall end on the last Business Day of the
last calendar month of such Eurodollar Interest Period.

          (iii) Determination of Interest Rate.  As soon as practicable after
                ------------------------------
11:00 a.m. (New York City, New York time) on any Eurodollar Interest Rate
Determination Date, the Lender shall determine (which determination shall,
absent manifest error, be presumptively correct) the interest rate which shall
apply to the Eurodollar Rate Loans for which an interest rate is then being
determined for the applicable Eurodollar Interest Period and shall promptly give
notice thereof (in writing or by telephone confirmed in writing) to the
Borrower.

                                       31
<PAGE>

          (iv)  Interest Rate Unascertainable, Inadequate or Unfair.  If, with
                ---------------------------------------------------
respect to any Eurodollar Interest Period, the Lender determines that (a)
deposits in Dollars (in the applicable amounts) are not being offered in the
relevant market for such Eurodollar Interest Period, (b) adequate and reasonable
means do not exist for ascertaining the Adjusted LIBO Rate, (c) a contingency
has occurred which materially and adversely affects the London interbank
Eurodollar market or (d) the effective cost to the Lender of funding a proposed
Funding Segment of the Eurodollar Portion from a corresponding source of funds
shall exceed the Eurodollar Rate, applicable to such Funding Segment, the Lender
shall forthwith give notice thereof to the Borrower, whereupon until the Lender
notifies the Borrower that the circumstances giving rise to such suspension no
longer exist, (1) the right of the Borrower to elect to have Revolving Credit
Loans bear interest based upon the Adjusted LIBO Rate shall be suspended and (2)
each outstanding Eurodollar Rate Loan shall be converted into a Base Rate Loan
on the last day of the then current Eurodollar Interest Period therefor,
notwithstanding any prior election by the Borrower to the contrary.

          (v)   Illegality. (a) In the event that on any date the Lender shall
                ----------
have determined (which determination shall, absent manifest error, be final and
conclusive and binding upon all parties) that the making or continuation of any
Eurodollar Rate Loan has become unlawful by compliance by the Lender in good
faith with any Law, of any Governmental Authority (whether or not having the
force of Law and whether or not failure to comply therewith would be unlawful),
then, and in any such event, the Lender shall promptly give notice (by telephone
promptly confirmed in writing) to the Borrower.

                (b)  Upon the giving of the notice referred to in Section
                                                                  -------
2.06(v)(a) hereof, (1) the Borrower's right to request of the Lender and the
----------
Lender's obligation to make Eurodollar Rate Loans shall be immediately
suspended, and the Lender shall make a Revolving Credit Loan, as part of any
requested Borrowing of Eurodollar Rate Loans, as a Base Rate Loan, which Base
Rate Loan shall, for all purposes, be considered a part of such Borrowing and
(2) if the affected Revolving Credit Loans are then outstanding, the Borrower
shall immediately (or, if permitted by applicable Law, no later than the date
permitted thereby, upon at least one (1) Business Day's written notice to the
Lender) convert each such Revolving Credit Loan into a Base Rate Loan.

                (c)  In the event that the Lender determines at any time
following its giving of the notice referred to in Section 2.06(iv) and Section
                                                  ----------------     -------
2.06(v)(a) hereof that the Lender may lawfully make Eurodollar Rate Loans of the
----------
type referred to in such notice, the Lender shall promptly give notice (by
telephone confirmed in writing) to the Borrower of that determination, whereupon
the Borrower's right to request of the Lender, and the Lender's obligation to
make, Eurodollar Rate Loans shall be restored.

          (vi)  Compensation.  In addition to such amounts as are required to be
                ------------
paid by the Borrower pursuant to Sections 2.02(iv), 2.02(vi), 2.03, 2.04(i),
                                 -------------------------------------------
2.06(vii), 2.07 and 2.09 hereof, the Borrower shall compensate the Lender, upon
---------------     ----
demand, for all losses, expenses and liabilities (including, without limitation,
any loss or expense incurred by reason of the liquidation or reemployment of
deposits or other funds required by the Lender to fund or maintain the Lender's
Eurodollar Rate Loans) which losses, expenses and liabilities the Lender may
sustain (a) if for any reason a Borrowing, conversion or continuation of
Eurodollar Rate Loans does not

                                       32
<PAGE>

occur on a date specified therefor in a Notice of Borrowing or a Notice of
Conversion/Continuation or in a telephonic request for borrowing or
conversion/continuation or a successive Eurodollar Interest Period does not
commence after notice therefor is given pursuant to Section 2.02(iii) hereof,
                                                    -----------------
(b) if any prepayment of an Eurodollar Rate Loan (including, without limitation,
any prepayment pursuant to Section 2.04 hereof) occurs for any reason on a date
                           ------------
which is not the last day of the applicable Eurodollar Interest Period, (c) as a
consequence of any required conversion of a Eurodollar Rate Loan to a Base Rate
Loan as a result of any of the events indicated in Section 2.06(v) or (d) as a
                                                   ---------------
consequence of any other failure by the Borrower to repay Eurodollar Rate Loans
when required by the terms of this Loan Agreement. The Lender shall deliver to
the Borrower a written statement as to such losses, expenses and liabilities
which statement shall be conclusive as to such amounts in the absence of
manifest error.

          (vii)  Eurodollar Rate Taxes.  The Borrower hereby agrees that:
                 ---------------------

                 (a) the Borrower shall pay, prior to the date on which
penalties attach thereto, all present and future income, stamp and other taxes,
levies, or costs and charges whatsoever imposed, assessed, levied or collected
on or in respect of a Revolving Credit Loan solely as a result of the interest
rate being determined by reference to the Adjusted LIBO Rate or the provisions
of this Loan Agreement relating to the Adjusted LIBO Rate or the recording,
registration, notarization or other formalization of any thereof or any payments
of principal, interest or other amounts made on or in respect of a Revolving
Credit Loan made to the Borrower when the interest rate is determined by
reference to the Adjusted LIBO Rate (all such taxes, levies, costs and charges
being hereinafter collectively called "Eurodollar Rate Taxes"); provided,
                                                                --------
however, that Eurodollar Rate Taxes shall not include net income or franchise
-------
taxes imposed by any jurisdiction. The Borrower shall also pay such additional
amounts equal to increases in net income or franchise taxes attributable to
payments made by the Borrower pursuant to this clause (a). Promptly after the
                                               ----------
date on which payment of any such Eurodollar Rate Tax is due pursuant to
applicable law, the Borrower will, at the request of the Lender, furnish to the
Lender evidence, in form and substance satisfactory to the Lender, that the
Borrower has met its obligation under this Section 2.06(vii); and
                                           -----------------

                 (b) the Borrower will indemnify the Lender against, and
reimburse the Lender on demand for, any Eurodollar Rate Taxes paid by the Lender
in respect of a Revolving Credit Loan made to the Borrower, as determined by the
Lender in its sole discretion. The Lender shall provide the Borrower with (1)
appropriate receipts for any payments or reimbursements made by the Borrower
pursuant to this clause (b) and (2) such information as may reasonably be
                 ----------
required to indicate the basis for such Eurodollar Rate Taxes; provided,
however, that if the Lender subsequently recovers, or receives a net tax benefit
with respect to, any amount of Eurodollar Rate Taxes previously paid by the
Borrower pursuant to this Section 2.06(vii)(b), the Lender shall, within thirty
                          --------------------
(30) days after receipt of such refund, and to the extent permitted by
applicable law, pay to the Borrower the amount of any such recovery or permanent
net tax benefit.

          (viii) Booking of Eurodollar Rate Loans.  The Lender may make, carry
                 --------------------------------
or transfer Eurodollar Rate Loans at, to, or for the account of, any of its
branch offices, agencies or the office of an Affiliate of the Lender; provided,
                                                                      --------
however, the Lender shall not be entitled to receive any greater amount under
-------
Section 2.02(vi) or Section 2.06(vii) hereof as a result of the
----------------    -----------------

                                       33
<PAGE>

transfer of any such Revolving Credit Loan than the Lender would be entitled to
immediately prior thereto unless (a) such transfer occurred at a time when
circumstances giving rise to the claim for such greater amount did not exist and
were not reasonably foreseeable in the view of the Lender and (b) such claim
would have arisen even if such transfer had not occurred.

          (ix) Affiliates Not Obligated.  No Eurodollar Affiliate or other
               ------------------------
Affiliate of the Lender shall be deemed a party to this Loan Agreement or shall
have any rights, liability or obligation under this Loan Agreement.

     Section 2.07   Increased Capital.  If either (i) the introduction of or any
                    -----------------
change in or in the interpretation of any Law or regulation or (ii) compliance
by the Lender with any guideline or request from any central bank or other
Governmental Authority (whether or not having the force of law and whether or
not the failure to comply therewith would be unlawful) affects or would affect
the amount of capital required or expected to be maintained by the Lender or any
corporation controlling the Lender and the Lender determines that the amount of
such capital is increased by or based upon the existence of the Lender's
commitment to make Revolving Credit Loans and other commitments of this type,
then, upon demand by the Lender, the Borrower shall immediately pay to the
Lender, from time to time as specified by the Lender, additional amounts
sufficient to compensate the Lender in the light of such circumstances, to the
extent that the Lender determines such increase in capital to be allocable to
the existence of the Lender's commitment to fund the Revolving Credit Facility.
A certificate as to such amounts submitted to the Borrower by the Lender, shall,
in the absence of manifest error, be conclusive and binding for all purposes.
The Lender shall make written demand on the Borrower for such additional amounts
no later than one hundred eighty (180) days after the Lender receives actual
notice or obtains actual knowledge of the promulgation of any law, rule,
regulation or interpretation, or occurrence of any other event, giving rise to a
claim by the Lender against the Borrower for any such additional amounts
pursuant to this Section 2.07.  The Lender shall furnish the Borrower with a
                 ------------
description of the reason for any such increased capital requirement.  In the
event that the Lender fails to make such written demand on the Borrower within
such time period, then the Borrower shall have no obligation to pay any such
additional amount with respect to claims accruing prior to the one hundred
eightieth (180/th/) day preceding the date on which such written demand is made.

     Section 2.08.  Authorized Officers of the Borrower.  The Borrower shall
                    -----------------------------------
notify the Lender in writing of the names of the officers and employees
authorized to request Revolving Credit Loans and shall provide the Lender with a
specimen signature of each such Authorized Officer.  The Lender shall be
entitled to rely conclusively on such officer's or employee's authority to
request such Revolving Credit Loans until the Lender receives written notice to
the contrary.  The Lender shall have no duty to verify the authenticity of the
signature on any written Notice of Borrowing or Notice of
Conversion/Continuation and, with respect to an oral request for such a
Revolving Credit Loan, the Lender shall have no duty to verify the identity of
any Person representing himself as one of the officers or employees authorized
to make such request on behalf of the Borrower.  The Lender shall not incur any
liability to the Borrower in acting upon any telephonic notice referred to above
which the Lender believes in good faith to have been given by a duly Authorized
Officer or other Person authorized to borrow on behalf of the Borrower or for
otherwise acting in good faith under this Section 2.08.
                                          ------------

     Section 2.09  Taxes.
                   -----

          (i)  Payments Net of Taxes.  All payments made by the Borrower under
               ---------------------
this Loan Agreement or any other Loan Document shall be made free and clear of,
and without reduction or withholding for or on account of, any present or future
income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions
or withholdings, now or hereafter imposed, levied, collected, withheld or
assessed by any Governmental Authority, and all liabilities with respect
thereto, excluding

               (a)  in the case of the Lender, income or franchise taxes imposed
on the Lender by the jurisdiction under the laws of which the Lender is
organized or any political subdivision or taxing authority thereof or therein or
as a result of a connection between the Lender and any jurisdiction and the
transactions contemplated hereby; and

               (b)  in the case of the Lender, income or franchise taxes imposed
by any jurisdiction in which the Lender's lending offices which make or book
Revolving Credit Loans, are located or any political subdivision or taxing
authority thereof or therein (all such non-excluded taxes, levies, imposts,
deductions, charges or withholdings being hereinafter called "Taxes"). If any
Taxes are required to be withheld or deducted from any amounts payable to the
Lender under this Loan Agreement or any other Loan Document, the Borrower shall
pay the relevant amount of such Taxes and the amounts so payable to the Lender
shall be increased to the extent necessary to yield to the Lender (after payment
of all Taxes) interest or any such other amounts payable hereunder at the rates
or in the amounts specified in this Loan Agreement and the other Loan Documents.
Whenever any Taxes are paid by the Borrower with respect to payments made in
connection with this Loan Agreement or any other Loan Document, as promptly as
possible thereafter, the Borrower shall send to the Lender for its own account a
certified copy of an original official receipt received by the Borrower showing
payment thereof.

          (ii) Indemnity.  The Borrower hereby indemnifies the Lender for the
               ---------
full amount of all Taxes attributable to payments by or on behalf of the
Borrower hereunder or under any of the other Loan Documents, any Taxes paid by
the Lender any present or future claims, liabilities or losses with respect to
or resulting from any omission to pay or delay in paying any Taxes (including
any incremental Taxes, interest or penalties that may become payable by the
Lender as a result of any failure to pay such Taxes), whether or not such Taxes
were correctly or legally asserted.  Such indemnification shall be made within
thirty (30) days from the date the Lender makes written demand therefor.

                                                                    -----------
and (b) above, then the Borrower shall remain and be liable for any such

deficiency.

     Section 9.04  No Notices.  In order to entitle the Lender to exercise any
                   ----------
remedy available to it under Section 9.02 of this Loan Agreement, it shall not
                             ------------
be necessary for the Lender to give any notice, other than such notice as may be
required expressly in this Loan Agreement or by

applicable law.

     Section 9.05  Agreement to Pay Attorneys' Fees and Expenses.  Upon the
                   ---------------------------------------------
occurrence and during the continuance of an Event of Default, as a result of
which the Lender shall require and employ attorneys or incur other expenses for
the collection of payments due or to become due or the enforcement or
performance or observance of any obligation or agreement on the part of the
Borrower contained herein, the Borrower shall, on demand, pay to the Lender, the
reasonable fees of such attorneys, costs and such other expenses so incurred by
them including, without limitation, post-judgment attorney's fees, costs and
other expenses.

     Section 9.06  No Additional Waiver Implied by One Waiver.  In the event any
                   ------------------------------------------
agreement contained in this Loan Agreement should be breached by any party and
thereafter waived by the other parties, such waiver shall be limited to the
particular breach so waived and shall not be deemed to waive any other breach
hereunder.

     Section 9.07  Failure to Exercise Rights.  Nothing herein contained shall
                   --------------------------
impose upon the Lender any obligation to enforce any terms, covenants or
conditions contained in this Loan Agreement and the other Loan Documents.
Failure of the Lender, in any one or more instances, to insist upon strict
performance by the Borrower of any terms, covenants or conditions of this Loan
Agreement and the other Loan Documents, shall not be considered or taken as a
waiver or relinquishment by the Lender of its right to insist upon and to
enforce in the future, by injunction or other appropriate legal or equitable
remedy, strict compliance by the Borrower with all the terms, covenants and
conditions of this Loan Agreement and the other Loan Documents.  The consent of
the Lender to any act or omission by the Borrower shall not be construed to be a
consent to any other or subsequent act or omission or to waive the requirement
for the Lender's consent to be obtained in any future or other instance.

     Section 9.08  WAIVER OF JURY TRIAL. THE BORROWER AND THE LENDER HEREBY
                   --------------------
WAIVE ANY AND ALL RIGHTS THAT THEY MAY NOW OR HEREAFTER HAVE UNDER THE LAWS OF
THE UNITED STATES OF AMERICA OR ANY STATE, TO A TRIAL BY JURY OF ANY AND ALL
ISSUES ARISING EITHER DIRECTLY OR INDIRECTLY IN ANY ACTION OR PROCEEDING BETWEEN
THE BORROWER, THE LENDER OR THEIR SUCCESSORS AND ASSIGNS, OUT OF OR IN ANY WAY
CONNECTED WITH THIS LOAN AGREEMENT AND THE OTHER LOAN DOCUMENTS.  IT IS INTENDED
THAT SAID WAIVER SHALL APPLY TO ANY AND ALL DEFENSES, RIGHTS, AND/OR
COUNTERCLAIMS IN ANY ACTION OR PROCEEDING.  THE BORROWER AND THE LENDER
RECOGNIZE THAT ANY DISPUTE ARISING IN CONNECTION WITH THE REVOLVING CREDIT
FACILITY IS LIKELY TO BE COMPLEX AND CONSEQUENTLY THEY WISH TO STREAMLINE AND
MINIMIZE THE COST OF THE DISPUTE RESOLUTION PROCESS BY AGREEING TO WAIVE THEIR
RIGHTS TO A JURY TRIAL.

     Section 9.09  Remedies Cumulative.  No remedy herein conferred upon or
                   -------------------
reserved to the Lender is intended to be exclusive of any other remedy or
remedies; but each and every such remedy shall be cumulative, and shall be in
addition to every other remedy given hereunder, or now or hereafter existing at
law or in equity or by statute.  No express or implied waiver by the

                                       68
<PAGE>

Lender of any Event of Default hereunder shall in any way be, or construed to
be, a waiver of any future or subsequent Event of Default. No delay or omission
to exercise any right or power accruing upon any Event of Default continuing as
aforesaid, shall impair any such right or power or shall be construed to be a
waiver of any such Event of Default, or acquiescence therein; and every such
right and power may be exercised from time to time and as often as may be deemed
expedient.

sentence may be unenforceable because it is violative of any law or public
policy, the Borrower shall contribute the maximum portion which it is permitted
to pay and satisfy under applicable law, to the payment and satisfaction of all
Indemnified Matters incurred by the Indemnified Parties.

     Section 10.03  Amendments and Waivers.  No amendment or modification of any
                    ----------------------
provision of this Loan Agreement shall be effective without the written
agreement of the Lender and the Borrower, and no termination or waiver of any
provision of this Loan Agreement, or consent to any departure by the Borrower

exception to, or be otherwise within the limitations of, another covenant shall
not avoid the occurrence of an Event of Default or Potential Event of Default if
such action is taken or condition exists.

     Section 10.05  Notices.  Unless otherwise specifically provided therein,
                    -------

thereof are subsequently invalidated, declared to be fraudulent or preferential,

enforceability of the remaining provisions or obligations under the Loan
Agreement or the other Loan Documents, shall not in any way be affected or
impaired thereby.  The invalidating, illegality or unenforceability of a
particular provision in a particular jurisdiction shall not render such
provision invalid, illegal or unenforceable in any other jurisdiction.

                    --------------------------------------------
Agreement and any amendments, waivers, consents, or supplements may be executed
in counterparts, each of which when so executed and delivered shall be deemed an
original, but all such counterparts together shall constitute but one and the
same instrument.  This Loan Agreement and each of the other Loan Documents shall
