<PAGE>

         (i) If, subsequent to the Closing Date, Holdings or any of its
     Subsidiaries shall incur or permit the incurrence of any Indebtedness
     (other than Indebtedness permitted pursuant to subsection 7.2(a) through
     and including subsection 7.2(k)), 100% of the Net Proceeds thereof shall be
     promptly ratably applied toward the prepayment of the Loans, the Facility A
     Loans and the Facility B Loans and, unless the Required Class Lenders shall
     have waived such requirement in writing, on or before the 60th day
     following the date of receipt of such Net Proceeds (such 60 day period,
     herein, the "Debt Prepayment Waiting Period"), the Commitments, the
     Facility A Commitments and the Facility B Commitments shall be permanently
     reduced as set forth in clause (iv) of this subsection 2.6(b) by the amount
     so prepaid on the last day of the Debt Prepayment Waiting Period. During
     the term of any Debt Prepayment Waiting Period, a portion of the
     Commitments, the Facility A Commitments and the Facility B Commitments
     equal to the amount of prepayments received in respect of the Loans, the
     Facility A Loans and the Facility B Loans, as applicable, from the issuance
     and/or incurrence of such Indebtedness shall be unavailable to Borrower and
     deemed excluded from each Lender's, Facility A Lender's and Facility B
     Lender's "Available Commitment" (as such term is defined herein and in each
     of the Facility A Credit Agreement and Facility B Credit Agreement) unless
     Borrower shall have received a written waiver of such mandatory commitment
     reduction from the Required Class Lenders. Nothing in this paragraph (b)
     shall be deemed to permit any Indebtedness not permitted by subsection 7.2.

         (ii) If, subsequent to the Original Closing Date, Holdings or any of
     its Subsidiaries shall receive Net Proceeds from any Asset Sale (other than
     in respect of a sale of all of the Capital Stock of the TCAS Subsidiary
     owned, directly or indirectly, by Borrower (a "Final TCAS Sale")), such Net
     Proceeds, subject to the Applicable Holdback (defined below) shall be
     promptly and ratably applied toward the prepayment of the Loans, the
     Facility A Loans and the Facility B Loans and permanent reduction of the
     Commitments, the Facility A Commitments and the Facility B Commitments as
     set forth in clause (iv) of this subsection 2.6(b); provided that Net
     Proceeds from any Asset Sales (other than in respect of a Final TCAS Sale)
     shall not be required to be so applied to the extent that such Net Proceeds
     are used by the Borrower or such Subsidiary to acquire assets to be
     employed in the business of the Borrower or its Subsidiaries within 365
     days of receipt thereof, but if such Net Proceeds, subject to the
     Applicable Holdback (as defined below), are not so used, 100% of the amount
     of such Net Proceeds not so used shall be applied toward the prepayment of
     the Loans and the permanent reduction of the Commitments as set forth in
     clause (iv) of this subsection

                                       3
<PAGE>

     2.6(b) on the earlier of (x) the 366th day after receipt of such Net
     Proceeds and (y) the date on which the Borrower has determined that such
     Net Proceeds shall not be so used. If Holdings, Borrower or any of its
     Subsidiaries shall receive Net Proceeds from a Final TCAS Sale, such Net
     Proceeds shall be applied on or prior to the third Business Day after
     receipt thereof toward prepayment of the Loans, the Facility A Loans and
     the Facility B Loans and, unless the Required Class Lenders shall have
     waived such requirement in writing, on or before the 60th day following the
     date of such Final TCAS Sale (such 60 day period, herein, the "TCAS Waiting
     Period"), the Commitments, the Facility A Commitments and the Facility B
     Commitments shall be permanently reduced as set forth in clause (iv) of
     this subsection 2.6(b) by the amount so prepaid on the last day of the TCAS
     Waiting Period. During the term of any TCAS Waiting Period, a portion of
     the Commitments, the Facility A Commitments and the Facility B Commitments
     equal to the amount of prepayments received in respect of the Loans, the
     Facility A Loans and the Facility B Loans from such Final TCAS Sale shall
     be unavailable to Borrower and deemed excluded from each Lender's, Facility
     A Lender's and Facility B Lender's "Available Commitment" (as such term is
     defined herein and in each of the Facility A Credit Agreement and Facility
     B Credit Agreement) unless Borrower shall have received a written waiver of
     such mandatory commitment reduction from the Required Class Lenders. As
     used herein, "Applicable Holdback" shall mean an amount of Net Proceeds not
     in excess of $20,000,000 derived from any Asset Sales (other than a Final
     TCAS Sale) occurring since the Original Closing Date that has not been
     applied toward the prepayment of Loans and the permanent reduction of the
     Commitments as set forth in clause (iv) of subsection 2.6(b) which Borrower
     and/or its applicable Subsidiary may retain and not apply as a mandatory
     prepayment without the requirement of utilizing the same to acquire assets
     to be employed in the business of the Borrower or such applicable
     Subsidiary; provided, that if any Event of Default shall have occurred and
     be continuing, the Applicable Holdback amount shall be automatically
     reduced to zero unless and until such Event of Default is acknowledged in
     writing by the Required Lenders (or all the Lenders in cases where the
     unanimous consent of the Lenders is required) as cured or waived.

         (iii) If, subsequent to the Closing Date, any Capital Stock (other than
     any Convertible Securities which shall for all purposes under this
     Agreement be deemed Indebtedness for borrowed money) shall be issued by
     Holdings, the Borrower or any of its Subsidiaries, an amount equal to 50%
     of the Net Proceeds thereof shall be promptly ratably applied toward the
     prepayment of the Loans on the date of issuance and, unless the Required
     Lenders shall have waived such requirement in writing, on or before the
     60th day following the date of receipt of such Net Proceeds (such 60 day
     period, herein, the "Equity Issuance Waiting Period"), the Commitments
     shall be permanently reduced as set forth in clause (iv) of this subsection
     2.6(b) by the amount so prepaid on the last day of the Equity Issuance
     Waiting Period. During the term of any Equity Issuance Waiting Period, a
     portion of the Commitments equal to the amount of prepayments received in
     respect of the Loans from the issuance of such Capital Stock shall be
     unavailable to Borrower for Loans and deemed excluded from each Lender's
     Available Commitment unless Borrower shall have received a written waiver
     of such mandatory commitment reduction from the Required Lenders. Nothing
     in this paragraph (b) shall be deemed to permit any issuance of Capital
     Stock not permitted by subsection 7.6.

         (iv) Except during any period in which an Event of Default has occurred
     and is continuing, any mandatory prepayments required by subsection
     2.6(b)(i) and (ii) shall be applied ratably to the outstanding principal
     amount of Facility A Loans, Facility B Loans and Loans, with a
     corresponding ratable permanent reduction of the Facility A Commitments,
     the Facility B Commitments and the Commitments as and when required by
     subsection 2.6(b)(i) and (ii). Commitment, Facility A Commitment and
     Facility B Commitment reductions made pursuant to subsections 2.6(b)(i) and
     (ii) (and

                                       4
<PAGE>

     the corresponding subsections of the Facility A Credit Agreement and the
     Facility B Credit Agreement) hereof shall be applied to each Lender's
     respective Commitment, each Facility A Lender's Facility A Commitment
     and/or each Facility B Lender's Facility B Commitment, as applicable, on a
     pro rata basis and shall reduce permanently such Commitments, Facility A
     Commitments and Facility B Commitments. In addition, except during any
     period in which an Event of Default has occurred and is continuing, any
     mandatory prepayments required by subsection 2.6(b)(iii) shall be applied
     ratably to the outstanding principal amount of Loans, with a corresponding
     permanent reduction of the Commitments as and when required by subsection
     2.6(b)(iii). The Commitment reductions made pursuant to subsection
     2.6(b)(iii) hereof shall be applied to each Lender's respective Commitment
     and shall reduce permanently such Commitments. At any time that an Event of
     Default has occurred and is continuing, all mandatory prepayments shall be
     applied in accordance with the terms of subsection 2.12 hereof (and the
     corresponding subsection of the Facility A Credit Agreement and the
     Facility B Credit Agreement). Mandatory prepayments shall not be subject to
     any minimum amount requirement.

<PAGE>

            (b) The Loans may from time to time be (i) Eurodollar Loans, (ii)

         as a Eurodollar Loan after the day that is one month prior to the
         applicable Termination Date.

         2.2 Procedure for Borrowing. The Borrower may borrow under the
Commitments during the Commitment Period on any Business Day, provided that the
Borrower shall give the Administrative Agent irrevocable notice (which notice
must be received by the Administrative Agent prior to (a) 11:00 A.M., New York
City time, three Business Days prior to the requested Borrowing Date, if all or
any part of the requested Loans are to be initially Eurodollar Loans, (b) 11:00

Borrowing Date, (iii) whether the borrowing is to be of Eurodollar Loans, Base
Rate Loans or a combination thereof and (iv) if the borrowing is to be entirely
or partly of Eurodollar Loans, the respective lengths of the initial Interest
Periods therefor. Each borrowing under the Commitments shall be in an amount
equal to (x) in the case of Base Rate Loans, $2,000,000 or a whole multiple of
$100,000 in excess thereof (or, if the then Available Commitments are less than
$2,000,000, such lesser amount), and (y) in the case of Eurodollar Loans,
$5,000,000 or a whole multiple of $100,000 in excess thereof; provided that the
Borrower may nevertheless borrow amounts below such minimum amounts in clauses
(x) or (y) above solely for the purpose of (i) repaying Loans owing to any
Nonconsenting Lenders on the Termination Date and (ii) permitting the addition
of any New Lender or increasing the Commitment of any existing Lender pursuant
to subsection 2.1(a)(i). Upon receipt of any such notice from the Borrower, the
Administrative Agent shall promptly notify each Lender thereof. Each Lender will
make the amount of its pro rata share of each borrowing available to the
Administrative Agent for the account of the Borrower at the office of the
Administrative Agent specified in subsection 10.2 prior to 11:00 A.M., New York
City time (in the case of Eurodollar Loans) or 2:30 P.M., New York City time (in

funds immediately available to the Administrative Agent. Such borrowing will
then be made available to the Borrower by the Administrative Agent in accordance
with the Borrower's payment instructions with the aggregate of the amounts made
available to the Administrative Agent by the Lenders and in like funds as
received by the Administrative Agent. All notices given by the Borrower under
this subsection 2.2 may be made by telephonic notice promptly confirmed in
writing.

Agent for the account of each Lender a commitment fee for the period from and

such dates to occur after the date hereof.

Administrative Agent, to

                                       24
<PAGE>

terminate the Commitments or, from time to time, to reduce the amount of the
Commitments ratably among the Lenders; provided that no such termination or
reduction shall be permitted if, after giving effect thereto and to any
prepayments of the Loans made on the effective date thereof, the aggregate
principal amount of the Loans then outstanding, would exceed the Commitments
then in effect. Any such reduction shall be in an amount equal to $2,000,000 or
a whole multiple of $500,000 in excess thereof and shall reduce permanently the
Commitments then in effect.

         2.5 Extension of Termination Date; Repayment of Loans; Evidence of
Debt.

            (a) Extension of Termination Date. The Borrower may elect to forward
         to the Administrative Agent (for distribution to each Lender) no
         earlier than sixty (60) but no later than fifty-five (55) days prior to
         the initially scheduled Termination Date a written request asking each
         Lender to consent to the extension of the Termination Date for one (1)
         additional 364 day period. Not later than 30 days after receipt of such
         written request, each Lender shall advise the Administrative Agent and
         the Borrower in writing whether such Lender consents to the proposed
         extension if all the conditions, including those set forth in
         subsection 5.2 of this Agreement, thereto have been satisfied. If all
         of the Lenders have consented in writing to such extension and all
         conditions set forth in subsection 5.2 shall have been satisfied, then
         effective on the initially scheduled Termination Date, the Termination
         Date shall be deemed automatically extended by an additional 364 day
         period (herein, the "Extension Option"). If less than all of the
         Lenders consent to the exercise of the proposed Extension Option (the
         "Extending Lenders"), the Borrower may replace all, some or none of
         such Nonconsenting Lenders on or before the initially scheduled
         Termination Date pursuant to subsection 2.17 and repay all outstanding
         Loans owing to each Nonconsenting Lender that is not being replaced, if
         any, on the initially scheduled Termination Date (without giving effect
         to the Extension Option); provided that if the Extending Lenders do not
         hold more than 50% of the outstanding Commitments, the Borrower will
         not be entitled to exercise the Extension Option with respect to any
         Extending Lenders nor shall any Lender failing to consent to the
         Extension Option be deemed a Nonconsenting Lender and be subject to
         replacement under subsection 2.17 as a result thereof. Subject to the
         foregoing proviso, if the Borrower desires to exercise the Extension
         Option with the Extending Lenders, Borrower shall provide the
         Administrative Agent (for distribution to each Lender) with not less
         than five (5) days prior written notice thereof in addition to
         satisfying all conditions precedent set forth above (other than the
         requirement that all Lenders have timely consented to the Extension
         Option). On the date the Extension Option becomes effective, Schedule I
         hereto shall be deemed amended to accurately reflect the Commitments of
         the Lenders then in existence and the Administrative Agent shall
         promptly deliver a copy of such amended Schedule I to each Lender and
         the Borrower.

            (b) [Intentionally Omitted].

                                       25
<PAGE>

            (c) Replacement of Nonconsenting Lenders. If any Lender declines to
         consent or fails to timely indicate its consent to the exercise by
         Borrower of the Extension Option and the Extending Lenders hold more
         than 50% of the Commitments, such Lender shall be deemed a
         Nonconsenting Lender and be subject to replacement in accordance with
         the terms of subsection 2.17 hereof.

            (d) Payments on Loans. The Borrower hereby unconditionally promises
         to pay to the Administrative Agent on the Termination Date (or such
         earlier date on which the Loans become due and payable pursuant to
         Section 8) for the account of each Lender the then unpaid principal
         amount of each Loan of such Lender.

            (e) Interest. The Borrower hereby further agrees to pay interest on
         the unpaid principal amount of the Loans from time to time outstanding
         from the date such Loans are made until payment in full thereof at the
         rates per annum, and on the dates, set forth in subsection 2.9.

            (f) Recording. Each Lender shall maintain in accordance with its
         usual practice an account or accounts evidencing indebtedness of the
         Borrower to such Lender resulting from each Loan of such Lender from
         time to time, including the amounts of principal and interest payable
         and paid to such Lender from time to time under this Agreement.

            (g) Loan Accounts and Register; Notes.

         (i) The Loans made by, and the Commitments of, each Lender shall be
     evidenced by one or more loan accounts ("Loan Accounts") maintained by such
     Lender and by the Register maintained by the Administrative Agent in the
     ordinary course of business. The Register maintained by the Administrative
     Agent shall, in the event of a discrepancy between the entries in the
     Administrative Agent's books and any Lender's books relating to such
     matters, be controlling and, absent manifest error, shall be conclusive as
     to the amount of the Loans made by the Lender to the Borrower, the interest
     and payments thereon and any other amounts owing in respect of this
     Agreement. The Borrower hereby designates the Administrative Agent to serve
     as the Borrower's agent, solely for purposes of this subsection 2.5(g) and
     subsection 10.6, to maintain the Register on which it will record the
     Commitments from time to time of each of the Lenders, the Loans made by
     each of the Lenders and each repayment in respect of the principal amount
     of the Loans of each Lender. The Borrower agrees to indemnify the
     Administrative Agent from and against any and all losses, claims, damages
     and liabilities of whatsoever nature which may be imposed on, asserted
     against or incurred by the Administrative Agent in performing its duties
     under this subsection 2.5(g) and subsection 10.6 (other than any losses,
     claims, damages and liabilities to the extent incurred by reason of the
     gross negligence or willful misconduct of the Administrative Agent).

         (ii) If requested by any Lender, the Borrower shall execute and deliver
     to such Lender (and deliver a copy thereof to the Administrative Agent) one
     or more promissory

                                       26

     notes evidencing the Loans owing to such Lender pursuant to this Agreement
     in accordance with subsection 2.5(i).

            (h) Prima Facie Evidence. The entries made in the Register and the
         Loan Accounts of each Lender maintained pursuant to subsection 2.5(g)
         shall, to the extent permitted by applicable law, be prima facie
         evidence of the existence and amounts of the obligations of the
         Borrower therein recorded; provided, however, that the failure of any
         Lender or the Administrative Agent to maintain the Register or any such
         Loan Account, or any error therein, shall not in any manner affect the
         obligation of the Borrower to repay (with applicable interest) the
         Loans made to the Borrower by such Lender in accordance with the terms
         of this Agreement. For the avoidance of doubt, the existence or
         non-existence of any Note representing any Obligations owing to any
         Lender hereunder shall not affect the existence, amount, validity or
         enforceability of such Obligations, which in all events shall be
         absolute and unconditional.

            (i) Notes. The Borrower agrees that the Borrower will execute and
         deliver to each Lender that requests any such Note pursuant to
         subsection 2.5(g)(ii), a promissory note of the Borrower evidencing the
         Loans of such Lender, substantially in the form of Exhibit A-1 with
         appropriate insertions as to date and principal amount (a "Note").

         2.6 Optional Prepayments; Mandatory Prepayments and Reduction of
Commitments.

            (a) Subject to subsections 2.12 and 2.16, the Borrower may at any
         time and from time to time prepay any Loans, in whole or in part,
         without premium or penalty, upon irrevocable notice to the
         Administrative Agent prior to 11:00 A.M., New York City time, three
         Business Days prior to the date of prepayment in the case of Eurodollar
         Loans or on any Business Day in the case of Base Rate Loans, specifying
         the date and amount of prepayment of the Loans (which Loans shall be
         prepaid on a pro rata basis among the applicable Lenders) and whether
         the prepayment is of Eurodollar Loans, Base Rate Loans or a combination
         thereof, and, if of a combination thereof, the amount allocable to
         each. Upon receipt of any such notice, the Administrative Agent shall
         promptly notify each applicable Lender thereof. If any such notice is
         given, the amount specified in such notice shall be due and payable on
         the date specified therein, together with any amounts payable pursuant
         to subsection 2.16. Partial prepayments shall be in an aggregate
         principal amount of $2,000,000 or a whole multiple of $100,000 in
         excess thereof.

         (b) (i) If, subsequent to the Closing Date, Holdings or any of its
     Subsidiaries shall incur or permit the incurrence of any Indebtedness
     (other than Indebtedness permitted pursuant to subsection 7.2), 100% of the
     Net Proceeds thereof shall be promptly ratably applied toward the
     prepayment of the Loans, the Facility A Loans and the Facility B Loans and
     permanent reduction of the Commitments, the Facility A Commitments and the
     Facility B Commitments as set forth in clause (iv) of

                                       27
<PAGE>

     this subsection 2.6(b). Nothing in this paragraph (b) shall be deemed to
     permit any Indebtedness not permitted by subsection 7.2.

         (ii) If, subsequent to the Original Closing Date, Holdings or any of
     its Subsidiaries shall receive Net Proceeds from any Asset Sale, such Net
     Proceeds, subject to the Applicable Holdback (defined below) shall be
     promptly and ratably applied toward the prepayment of the Loans, the
     Facility A Loans and the Facility B Loans and permanent reduction of the
     Commitments, the Facility A Commitments and the Facility B Commitments as
     set forth in clause (iv) of this subsection 2.6(b); provided that Net
     Proceeds from any Asset Sales shall not be required to be so applied to the
     extent that such Net Proceeds are used by the Borrower or such Subsidiary
     to acquire assets to be employed in the business of the Borrower or its
     Subsidiaries within 365 days of receipt thereof, but if such Net Proceeds,
     subject to the Applicable Holdback (as defined below), are not so used,
     100% of the amount of such Net Proceeds not so used shall be applied toward
     the prepayment of the Loans and the permanent reduction of the Commitments
     as set forth in clause (iv) of this subsection 2.6(b) on the earlier of (x)
     the 366th day after receipt of such Net Proceeds and (y) the date on which
     the Borrower has determined that such Net Proceeds shall not be so used. As
     used herein, "Applicable Holdback" shall mean an amount of Net Proceeds not
     in excess of $20,000,000 derived from any Asset Sales occurring since the
     Original Closing Date that has not been applied toward the prepayment of
     Loans and the permanent reduction of the Commitments as set forth in clause
     (iv) of subsection 2.6(b) which Borrower and/or its applicable Subsidiary
     may retain and not apply as a mandatory prepayment without the requirement
     of utilizing the same to acquire assets to be employed in the business of
     the Borrower or such applicable Subsidiary; provided, that if any Event of
     Default shall have occurred and be continuing, the Applicable Holdback
     amount shall be automatically reduced to zero unless and until such Event
     of Default is acknowledged in writing by the Required Lenders (or all the
     Lenders in cases where the unanimous consent of the Lenders is required) as
     cured or waived.

         (iii) If, subsequent to the Closing Date, any Capital Stock shall be
     issued by Holdings, the Borrower or any of its Subsidiaries, an amount
     equal to 50% of the Net Proceeds thereof shall be promptly ratably applied
     on the date of such issuance toward the prepayment of the Loans, and
     permanent reduction of the Commitments, as set forth in clause (iv) of this
     subsection 2.6(b). Nothing in this paragraph (b) shall be deemed to permit
     any issuance of Capital Stock not permitted by subsection 7.6.

         (iv) Except during any period in which an Event of Default has occurred
     and is continuing, any mandatory prepayments required by subsection
     2.6(b)(i) and (ii) shall be applied ratably to the outstanding principal
     amount of Facility A Loans, Facility B Loans and Loans, with a
     corresponding ratable permanent reduction of the Facility A Commitments,
     the Facility B Commitments and the Commitments. Commitment, Facility A
     Commitment and Facility B Commitment reductions made pursuant to
     subsections 2.6(b)(i) and (ii) (and the corresponding subsections of the
     Facility A Credit Agreement and the Facility B Credit Agreement) hereof
     shall be applied to each Lender's respective Commitment, each Facility A
     Lender's Facility A Commitment and/or each

                                       28
<PAGE>

     Facility B Lender's Facility B Commitment, as applicable, on a pro rata
     basis and shall reduce permanently such Commitments, Facility A Commitments
     and Facility B Commitments. In addition, except during any period in which
     an Event of Default has occurred and is continuing, any mandatory
     prepayments required by subsection 2.6(b)(iii) shall be applied ratably to
     the outstanding principal amount of Loans, with a corresponding permanent
     reduction of the Commitments. The Commitment reductions made pursuant to
     subsection 2.6(b)(iii) hereof shall be applied to each Lender's respective
     Commitment and shall reduce permanently such Commitments. At any time that
     an Event of Default has occurred and is continuing, all mandatory
     prepayments shall be applied in accordance with the terms of subsection
     2.12 hereof (and the corresponding subsection of the Facility A Credit
     Agreement and the Facility B Credit Agreement). Mandatory prepayments shall
     not be subject to any minimum amount requirement.

         (v) If after giving effect to any reduction of the Commitments under
     subsection 2.4, 2.5 or 2.6, the aggregate outstanding principal amount of
     Loans shall exceed the aggregate amount of the Commitments, such reduction
     or recalculation shall be accompanied by prepayment in the amount of such
     excess to be applied to the Loans.

         2.7 Conversion and Continuation Options.

            (a) The Borrower may elect from time to time to convert Eurodollar
         Loans to Base Rate Loans, by giving the Administrative Agent prior
         irrevocable notice of such election at or before 11:00 A.M. New York
         City time, on the Business Day immediately preceding the date of the
         proposed conversion and of the amount to be converted, provided that
         any such conversion of Eurodollar Loans may only be made on the last
         day of an Interest Period with respect thereto. The Borrower may elect
         from time to time to convert Base Rate Loans to Eurodollar Loans by
         giving the Administrative Agent prior irrevocable notice of such
         election at or before 11:00 A.M., New York City time, on the third
         Business Day immediately preceding the date of the proposed conversion
         and of the amount to be converted. Any such notice of conversion to
         Eurodollar Loans shall specify the length of the initial Interest
         Period or Interest Periods therefor. Upon receipt of any such notice
         the Administrative Agent shall promptly notify each applicable Lender
         thereof. All or any part of outstanding Eurodollar Loans and Base Rate
         Loans may be converted as provided herein, provided that (i) no Loan
         may be converted into a Eurodollar Loan when any Event of Default has
         occurred and is then continuing and (ii) no Loan may be converted into
         a Eurodollar Loan after the date that is one month prior to the
         Termination Date with respect to such Loan.

            (b) Any Eurodollar Loans may be continued as such upon the
         expiration of the then current Interest Period with respect thereto by
         the Borrower giving notice to the Administrative Agent, in accordance
         with the applicable provisions of the term "Interest Period" set forth
         in subsection 1.1, of the length of the next Interest Period to be
         applicable to such Loans and of the amount to be converted, provided
         that no Eurodollar Loan may be continued as such (i) when

                                       29
<PAGE>

         any Event of Default has occurred and is then continuing or (ii) after
         the date that is one month prior to the Termination Date with respect
         to such Loan and provided, further, that if the Borrower shall fail to
         give such notice or if such continuation is not permitted such Loans
         shall be automatically converted to Base Rate Loans on the last day of
         such then expiring Interest Period.

            (c) All notices given by Borrower under this subsection 2.7 may be
         made by telephonic notice promptly confirmed in writing.

         2.8 Minimum Amounts and Maximum Number of Tranches. All borrowings,
conversions and continuations of Loans hereunder and all selections of Interest
Periods hereunder shall be in such amounts and be made pursuant to such
elections so that, after giving effect thereto, the aggregate principal amount
of the Loans comprising each Eurodollar Tranche shall be equal to $5,000,000 or
a whole multiple of $100,000 in excess thereof; provided that the Borrower may
nevertheless borrow amounts in any Eurodollar Tranche below such minimum amounts
solely for the purpose of (i) repaying Loans owing to any Nonconsenting Lenders
on the Termination Date or (ii) permitting the addition of any New Lender or any
increasing the Commitment of any existing Lender pursuant to subsection
2.1(a)(i). All Loans hereunder may be converted or continued into Base Rate
Loans without reference to the minimum principal amount requirements for new
Base Rate borrowings set forth in subsection 2.2 above. In no event shall the
number of outstanding Eurodollar Tranches under this Agreement plus the number
of outstanding Facility A Eurodollar Tranches and Facility B Eurodollar Tranches
exceed 20 at any time.

         2.9 Interest Rates and Payment Dates.

            (a) Each Eurodollar Loan shall bear interest for each day during
         each Interest Period with respect thereto at a rate per annum equal to
         the Eurodollar Rate determined for such day plus the Applicable Margin.

            (b) Each Base Rate Loan shall bear interest at a rate per annum
         equal to the Base Rate plus the Applicable Margin.

            (c) If all or a portion of (i) any principal of any Loan, (ii) any
         interest payable thereon, (iii) any commitment fee or (iv) any other
         amount payable hereunder shall not be paid when due (whether at the
         stated maturity, by acceleration or otherwise), the principal of the
         Loans and any such overdue interest, commitment fee or other amount
         shall bear interest at a rate per annum which is (x) in the case of
         principal, the rate that would otherwise be applicable thereto pursuant
         to the foregoing provisions of this subsection plus 2% or (y) in the
         case of any such overdue interest, commitment fee or other amount, the
         rate described in paragraph (b) of this subsection plus 2%, in each
         case from the date of such non-payment until such overdue principal,
         interest, commitment fee or other amount is paid in full (as well after
         as before judgment).

                                       30
<PAGE>

            (d) Interest shall be payable with respect to each Loan in arrears
         on each Interest Payment Date and on the Termination Date with respect
         to such Loan, provided that interest accruing pursuant to paragraph (c)
         of this subsection shall be payable from time to time on demand.

            2.10 Computation of Interest and Fees.

            (a) Interest on Base Rate Loans and fees shall be calculated on the
         basis of a 365- (or 366-, as the case may be) day year for the actual
         days elapsed; all other interest shall be calculated on the basis of a
         360-day year for the actual days elapsed. The Administrative Agent
         shall as soon as practicable notify the Borrower and the Lenders of
         each determination of a Eurodollar Rate. Any change in the interest
         rate on a Loan resulting from a change in the Base Rate or the
         Eurocurrency Reserve Requirements shall become effective as of the
         opening of business on the day on which such change becomes effective.
         The Administrative Agent shall as soon as practicable notify the
         Borrower and the Lenders of the effective date and the amount of each
         such change in interest rate.

            (b) Each determination of an interest rate by the Administrative
         Agent pursuant to any provision of this Agreement shall be conclusive
         and binding on the Borrower and the Lenders in the absence of manifest
         error. The Administrative Agent shall, at the request of the Borrower,
         deliver to the Borrower a statement showing the quotations used by the
         Administrative Agent in determining any interest rate pursuant to
         subsection 2.9(a) or (c).

            2.11 Inability to Determine Interest Rate. If prior to the first day
of any Interest Period:

            (a) the Administrative Agent shall have determined (which
         determination shall be conclusive and binding upon the Borrower) that,
         by reason of circumstances affecting the eurodollar market, adequate
         and reasonable means do not exist for ascertaining the Eurodollar Rate
         for such Interest Period, or

            (b) the Administrative Agent shall have received notice from the
         Required Lenders that the Eurodollar Rate determined or to be
         determined for such Interest Period will not adequately and fairly
         reflect the cost to such Lenders (as conclusively certified by such
         Lenders) of making or maintaining their affected Loans during such
         Interest Period, the Administrative Agent shall give telecopy or
         telephonic notice thereof to the Borrower and the Lenders as soon as
         practicable thereafter. If such notice is given (x) any Eurodollar
         Loans requested to be made on the first day of such Interest Period
         shall be made as Base Rate Loans, (y) any Loans that were to have been
         converted on the first day of such Interest Period to Eurodollar Loans
         shall be converted to or continued as Base Rate Loans and (z) any
         outstanding Eurodollar Loans shall be converted, on the first day of
         such Interest Period, to Base Rate Loans. Until such notice has been
         withdrawn in writing by the Administrative Agent (which the
         Administrative Agent agrees to do when the Administrative Agent has
         determined, or has been instructed

                                       31
<PAGE>

         by the Required Lenders that, the circumstances that prompted the
         delivery of such notice no longer exist), no further Eurodollar Loans
         shall be made or continued as such, nor shall the Borrower have the
         right to convert Loans to Eurodollar Loans.

            2.12 Pro Rata Treatment and Payments.

            (a) Each borrowing by the Borrower from the Lenders hereunder, each
         payment by the Borrower on account of any commitment fee hereunder and
         any reduction of the Commitments of Lenders shall be made pro rata
         according to the respective Commitment Percentages of the Lenders.
         Except during any period in which an Event of Default has occurred and
         is continuing, each payment (including each prepayment) by the Borrower
         on account of principal of and interest on the Loans, and any
         application by the Administrative Agent of the proceeds of any
         Collateral, shall be made pro rata according to the respective
         outstanding principal amounts of such Loans then held by the Lenders.
         All payments (including prepayments) to be made by the Borrower
         hereunder in respect of any Loan, whether on account of principal,
         interest, fees, expenses or otherwise, shall be made without set off or
         counterclaim and shall be made prior to 11:00 A.M., New York City time,
         on the due date thereof to the Administrative Agent, for the account of
         the Lenders with respect to such Loans, at the Administrative Agent's
         office specified in subsection 10.2, in Dollars and in immediately
         available funds. At any time that an Event of Default has occurred and
         is continuing, all payments (including prepayments) made by Borrower
         hereunder and any application by the Administrative Agent of the
         proceeds of any Collateral and/or payment under any Guarantee shall be
         applied in the following order: (1) to the ratable payment of all
         amounts due and owing by the Borrower pursuant to subsection 10.5 of
         this Agreement, subsection 10.5 of the Facility A Credit Agreement or
         subsection 10.5 or the Facility B Credit Agreement to the Agents, the
         Facility A Agents and/or the Facility B Agents and, after payment in
         full thereof, to any other Lender, Facility A Lender or Facility B
         Lender; (2) to the ratable payment of all interest, fees and
         commissions due and owing under this Agreement, the Facility A Credit
         Agreement or the Facility B Credit Agreement or to the Agents, the
         Facility B Agents, the Facility A Agents, the Swing Line Lender, any
         Lender, any Facility A Lender or any Facility B Lender; (3) to the
         ratable payment (or cash collateralization) of the aggregate
         outstanding principal amount of Loans, Facility A Loans and Facility B
         Loans and the aggregate Facility A L/C Obligations and Facility B L/C
         Obligations; and (4) to the ratable payment of all other obligations of
         the Borrower to the Agents, the Facility A Agents, the Facility B
         Agents, the Swing Line Lender, any Lender, any Facility A Lender or any
         Facility B Lender under any Credit Document, Facility A Credit Document
         or Facility B Credit Document. The Administrative Agent, the Facility A
         Administrative Agent and the Facility B Administrative Agent shall
         ratably distribute such payments to the applicable Lenders, the
         Facility A Lenders and the Facility B Lenders promptly upon receipt in
         like funds as received. If any payment hereunder becomes due and
         payable on a day other than a Business Day, such payment shall be
         extended to the next succeeding Business Day, and, with

                                       32
<PAGE>

         respect to payments of principal, interest thereon shall be payable at
         the then applicable rate during such extension.

            (b) Unless the Administrative Agent shall have been notified in
         writing by any Lender prior to a borrowing that such Lender will not
         make the amount that would constitute its Commitment Percentage of such
         borrowing available to the Administrative Agent, the Administrative
         Agent may assume that such Lender is making such amount available to
         the Administrative Agent on such Borrowing Date, and the Administrative
         Agent may, in reliance upon such assumption, make available to the
         Borrower a corresponding amount. If such amount is not made available
         to the Administrative Agent by the required time on the Borrowing Date
         therefor, such Lender shall pay to the Administrative Agent, on demand,
         such amount with interest thereon at a rate equal to the daily average
         Federal Funds Effective Rate for the period until such Lender makes
         such amount immediately available to the Administrative Agent. A
         certificate of the Administrative Agent submitted to any Lender with
         respect to any amounts owing under this subsection shall be conclusive
         in the absence of manifest error. If such Lender's Commitment
         Percentage of such borrowing is not made available to the
         Administrative Agent by such Lender within three Business Days of such
         Borrowing Date, the Administrative Agent shall also be entitled to
         recover such amount with interest thereon at the rate per annum
         applicable to Base Rate Loans hereunder, on demand, from the Borrower.
         The failure of any Lender to make any Loan to be made by it shall not
         relieve any other Lender of its obligation hereunder to make its Loan
         on such Borrowing Date.

         2.13 Illegality. Notwithstanding any other provision herein, if the
adoption of or any change in any Requirement of Law or in the interpretation or
application thereof shall make it unlawful for any Lender to make or maintain
Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such
Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and
convert Base Rate Loans to Eurodollar Loans shall forthwith be canceled and (b)
such Lender's Loans then outstanding as Eurodollar Loans, if any, shall be
converted automatically to Base Rate Loans on the respective last days of the
then current Interest Periods with respect to such Loans or within such earlier
period as required by law. If any such conversion of a Eurodollar Loan occurs on
a day which is not the last day of the then current Interest Period with respect
thereto, the Borrower shall pay to such Lender such amounts, if any, as may be
required pursuant to subsection 2.16. If circumstances subsequently change so
that any affected Lender shall determine that it is no longer so affected, such
Lender will promptly notify the Borrower and the Administrative Agent, and upon
receipt of such notice, the obligations of such Lender to make or continue
Eurodollar Loans or to convert Base Rate Loans into Eurodollar Loans shall be

         2.14 Requirements of Law.

            (a) If the adoption of or any change in any Requirement of Law or in
         the interpretation or application thereof or compliance by any Lender
         with any

                                       33
<PAGE>

         request or directive (whether or not having the force of law) from any
         central bank or other Governmental Authority made subsequent to the
         date hereof:

         (i) shall subject any Lender to any tax of any kind whatsoever with
     respect to this Agreement, any Note or any Eurodollar Loan made by it, or
     change the basis of taxation of payments to such Lender in respect thereof
     (except for Non-Excluded Taxes covered by subsection 2.15 and changes in
     the rate of net income taxes (including branch profits taxes and minimum
     taxes) or franchise taxes (imposed in lieu of net income taxes) of such
     Lender);

         (ii) shall impose, modify or hold applicable any reserve, special
     deposit, compulsory loan or similar requirement against assets held by,
     deposits or other liabilities in or for the account of, advances, loans or
     other extensions of credit by, or any other acquisition of funds by, any
     office of such Lender which is not otherwise included in the determination
     of the Eurodollar Rate hereunder; or

         (iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or to reduce any amount receivable
hereunder in respect thereof, then, in any such case, the Borrower shall
promptly pay such Lender upon written demand such additional amount or amounts
as will compensate such Lender for such increased cost or reduced amount
receivable; provided that before making any such demand, each Lender agrees to
use reasonable efforts (consistent with its internal policy and legal and
regulatory restrictions and so long as such efforts would not be disadvantageous
to it, in its reasonable discretion, in any legal, economic or regulatory
manner) to designate a different Eurodollar lending office if the making of such
designation would allow the Lender or its Eurodollar lending office to continue
to perform its obligations to make Eurodollar Loans or to continue to fund or
maintain Eurodollar Loans and avoid the need for, or reduce the amount of, such
increased cost. If any Lender becomes entitled to claim any additional amounts
pursuant to this subsection, it shall promptly notify the Borrower, through the
Administrative Agent, of the event by reason of which it has become so entitled.
If the Borrower so notifies the Administrative Agent within five Business Days
after any Lender notifies the Borrower of any increased cost pursuant to the
foregoing provisions of this Section, the Borrower may convert all Eurodollar
Loans of such Lender then outstanding into Base Rate Loans in accordance with
the terms hereof. Each Lender shall notify the Borrower within 120 days after it
becomes aware of the imposition of such costs; provided that if such Lender
fails to so notify the Borrower within such 120-day period, such Lender shall
not be entitled to claim any additional amounts pursuant to this subsection for
any period ending on a date which is prior to 120 days before such notification.

            (b) If any Lender shall have determined that the adoption of or any
         change in any Requirement of Law regarding capital adequacy or in the
         interpretation or application thereof or compliance by such Lender or
         any corporation controlling such Lender with any request or directive
         regarding capital adequacy (whether or not having the force of law)
         from any Governmental

                                       34
<PAGE>

         Authority made subsequent to the date hereof shall have the effect of
         reducing the rate of return on such Lender's or such corporation's
         capital as a consequence of its obligations hereunder to a level below
         that which such Lender or such corporation could have achieved but for
         such adoption, change or compliance (taking into consideration such
         Lender's or such corporation's policies with respect to capital
         adequacy) by an amount deemed by such Lender to be material, then from
         time to time, after submission by such Lender to the Borrower (with a
         copy to the Administrative Agent) of a prompt written request therefor,
         the Borrower shall promptly pay to such Lender such additional amount
         or amounts as will compensate such Lender for such reduction. Each
         Lender shall notify the Borrower within 120 days after it becomes aware
         of the imposition of such additional amount or amounts; provided that
         if such Lender fails to so notify the Borrower within such 120-day
         period, such Lender shall not be entitled to claim any additional
         amount or amounts pursuant to this subsection for any period ending on
         a date which is prior to 120 days before such notification.

            (c) If any Lender becomes entitled to claim any additional amounts
         pursuant to this subsection, it shall promptly notify the Borrower
         (with a copy to the Administrative Agent) of the event by reason of
         which it has become so entitled. A certificate as to any additional
         amounts payable pursuant to this subsection, showing the calculation
         thereof in reasonable detail, submitted by such Lender to the Borrower
         (with a copy to the Administrative Agent) shall be conclusive in the
         absence of manifest error. The agreements in this subsection shall
         survive the termination of this Agreement and the payment of the Loans
         and all other amounts payable hereunder.

         2.15  Taxes.

            (a) Except as provided in this subsection 2.15, all payments made by
         the Borrower under this Agreement and any Notes shall be made free and
         clear of, and without deduction 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 ("Taxes"), excluding Taxes on net income (including, without
         limitation, branch profits taxes and minimum taxes) and franchise taxes
         (imposed in lieu of net income taxes) imposed on any Agent or any
         Lender as a result of a present or former connection between any Agent
         or such Lender and the jurisdiction of the Governmental Authority
         imposing such tax or any political subdivision or taxing authority
         thereof or therein (other than any such connection arising solely from
         such Agent or such Lender having executed, delivered or performed its
         obligations or received a payment under, or enforced, this Agreement or
         any Note). If any such non-excluded taxes, levies, imposts, duties,
         charges, fees deductions or withholdings ("Non-Excluded Taxes") are
         required to be withheld from any amounts payable to any Agent or any
         Lender hereunder or under any Note, the amounts so payable to such
         Agent or such Lender shall be increased to the extent necessary to
         yield to such Agent or such

                                       35
<PAGE>

         Lender (after payment of all Non-Excluded Taxes) interest or any such
         other amounts payable hereunder at the rates or in the amounts
         specified in this Agreement, provided, however, that the Borrower shall
         not be required to increase any such amounts payable to any Lender that
         is not organized under the laws of the United States of America or a
         state thereof with respect to any Taxes that are imposed on amounts
         payable to such Lender at the time such Lender becomes a party to this
         Agreement or that are attributable to such Lender's failure to comply
         with the requirements of paragraph (b) of this subsection. Whenever any
         Non-Excluded Taxes are payable by the Borrower, as promptly as possible
         thereafter, the Borrower shall send to the relevant Agent for its own
         account or for the account of such Lender, as the case may be, a
         certified copy of an original official receipt, if any, received by the
         Borrower showing payment thereof. If the Borrower fails to pay any
         Non-Excluded Taxes when due to the appropriate taxing authority or
         fails to remit to the relevant Agent the required receipts or other
         required documentary evidence, the Borrower shall indemnify the Agents
         and the Lenders for any incremental taxes, interest or penalties that
         may become payable by any Agent or any Lender as a result of any such
         failure. The agreements in this subsection shall survive the
         termination of this Agreement and the payment of the Loans and all
         other amounts payable hereunder.

            (b) Each Lender, Assignee and Participant that is not a citizen or
         resident of the United States of America, a corporation, partnership
         created or organized in or under the laws of the United States of
         America, any estate that is subject to U.S. federal income taxation
         regardless of the source of its income or any trust which is subject to
         the supervision of a court within the United States and the control of
         a United States fiduciary as described in Section 7701(a)(30) of the
         Code (a "Non-U.S. Lender") shall deliver to the Borrower and the
         Administrative Agent, and if applicable, the assigning Lender (or, in
         the case of a Participant, to the Lender from which the related
         participation shall have been purchased) on or before the date on which
         it becomes a party to this Agreement (or, in the case of a Participant,
         on or before the date on which such Participant purchases the related
         participation) either:

         (A) two duly completed and signed copies of either Internal Revenue
     Service Form W-8 ECI (relating to such Non-U.S. Lender and entitling it to
     a complete exemption from withholding of U.S. Taxes on all amounts to be
     received by such Non-U.S. Lender pursuant to this Agreement and the other
     Credit Documents) or Form W-8 BEN (relating to all amounts to be received
     by such Non-U.S. Lender pursuant to this Agreement and the other Credit
     Documents), or successor and related applicable forms, as the case may be;
     or

         (B) in the case of a Non-U.S. Lender that is not a "bank" within the
     meaning of Section 881(c)(3)(A) of the Code and that does not comply with
     the requirements of clause (A) hereof, (x) a statement in the form of
     Exhibit E (or such other form of statement as shall be reasonably requested
     by the Borrower from time to time) to the effect that such Non-U.S. Lender
     is eligible for a complete exemption from withholding

                                       36
<PAGE>

     of U.S. Taxes under Code Section 871(h) or 881(c), and (y) two duly
     completed and signed copies of Internal Revenue Service Form W-8 or
     successor and related applicable form (it being understood and agreed that
     no Participant and, without the prior written consent of the Borrower
     described in clause (B) of the proviso to the first sentence of subsection
     10.6(c), no Assignee shall be entitled to deliver any forms or statements
     pursuant to this clause (B), but rather shall be required to deliver forms
     pursuant to clause (A) of this subsection 2.15(b)).

Further, each Non-U.S. Lender agrees (i) to deliver to the Borrower and the
Administrative Agent, and if applicable, the assigning Lender (or, in the case
of a Participant, to the Lender from which the related participation shall have
been purchased) two further duly completed and signed copies of such Forms W-8
ECI or W-8 BEN, as the case may be, or successor and related applicable forms,
on or before the date that any such form expires or becomes obsolete and
promptly after the occurrence of any event requiring a change from the most
recent form(s) previously delivered by it to the Borrower (or, in the case of a
Participant, to the Lender from which the related participation shall have been
purchased) in accordance with applicable U.S. laws and regulations and (ii) in
the case of a Non-U.S. Lender that delivers a statement in the form of Exhibit E
(or such other form of statement as shall have been requested by the Borrower),
to deliver to the Borrower and the Administrative Agent, and if applicable, the
assigning Lender, such statement on an annual basis on the anniversary of the
date on which such Non-U.S. Lender became a party to this Agreement and to
deliver promptly to the Borrower and the Administrative Agent, and if
applicable, the assigning Lender, such additional statements and forms as shall
be reasonably requested by the Borrower from time to time unless, in any such
case, any change in law or regulation has occurred subsequent to the date such
Lender became a party to this Agreement (or in the case of a Participant, the
date on which such Participant purchased the related participation) which
renders all such forms inapplicable or which would prevent such Lender (or
Participant) from properly completing and executing any such form with respect
to it and such Lender promptly notifies the Borrower and the Administrative
Agent (or, in the case of a Participant, the Lender from which the related
participation shall have been purchased) if it is no longer able to deliver, or
if it is required to withdraw or cancel, any form or statement previously
delivered by it pursuant to this subsection 2.15(b). Each Non-U.S. Lender agrees
to indemnify and hold harmless the Borrower from and against any taxes,
penalties, interest or other costs or losses (including, without limitation,
reasonable attorneys' fees and expenses) incurred or payable by the Borrower as
a result of the failure of the Borrower to comply with its obligations to deduct
or withhold any U.S. Taxes from any payments made pursuant to this Agreement to
such Non-U.S. Lender or the Administrative Agent which failure resulted from the
Borrower's reliance on any form, statement, certificate or other information
provided to it by such Non-U.S. Lender pursuant to clause (B) or clause (ii) of
this subsection 2.15(b). The Borrower hereby agrees that for so long as a
Non-U.S. Lender complies with this subsection 2.15(b), the Borrower shall not
withhold any amounts from any payments made pursuant to this Agreement to such
Non-U.S. Lender, unless the Borrower reasonably determines that it is required
by law to withhold or deduct any amounts from any payments made to such Non-U.S.
Lender pursuant to this Agreement. A Non-U.S. Lender shall not be required to
deliver any form or statement pursuant to the immediately preceding sentences in
this subsection 2.15(b) that such Non-U.S. Lender is not legally able to deliver
(it being understood and agreed

                                       37
<PAGE>

that the Borrower shall withhold or deduct such amounts from any payments made
to such Non-U.S. Lender that the Borrower reasonably determines are required by
law and that payments resulting from a failure to comply with this paragraph (b)
shall not be subject to payment or indemnity by the Borrower pursuant to
subsection 2.15(a)). If any Credit Party other than the Borrower makes any
payment to any Non-U.S. Lender under any Credit Document, the foregoing
provisions of this subsection 2.15 shall apply to such Non-U.S. Lender and such
Credit Party as if such Credit Party were the Borrower (but a Non-U.S. Lender
shall not be required to provide any form or make any statement to any such
Credit Party unless such Non-U.S. Lender has received a request to do so from
such Credit Party and has a reasonable time to comply with such request).

            (c) If a Lender shall become aware that it is entitled to receive a
         refund (whether by way of a direct payment or by offset) in respect of
         a Non-Excluded Tax paid by the Borrower, which refund, in the good
         faith judgment of such Lender, is allocable to such payment made
         pursuant to this Section, it shall promptly notify the Borrower of the
         availability of such refund and shall, within 30 days after the receipt
         of a request from the Borrower, apply for such refund at the Borrower's
         sole expense. If any Lender receives such refund (as described in the
         preceding sentence), it shall repay the amount of such refund (together
         with any interest received thereon) to the Borrower if all the payments
         due under this Section has been paid in full.

         2.16 Indemnity. The Borrower agrees to indemnify each Lender and to
hold each Lender harmless from any loss or expense which such Lender may sustain
or incur as a consequence of (a) default by the Borrower in making a borrowing
of, conversion into or continuation of Eurodollar Loans after the Borrower has
given a notice requesting the same in accordance with the provisions of this
Agreement, (b) default by the Borrower in making any prepayment after the
Borrower has given a notice thereof in accordance with the provisions of this
Agreement or (c) the making of a prepayment of Eurodollar Loans on a day which
is not the last day of an Interest Period with respect thereto (but excluding
loss of margin). Such indemnification under this subsection 2.16 may include an
amount equal to the excess, if any, of (i) the amount of interest which would
have accrued on the amount so prepaid, or not so borrowed, converted or
continued, for the period from the date of such prepayment or of such failure to
borrow, convert or continue to the last day of such Interest Period (or, in the
case of a failure to borrow, convert or continue, the Interest Period that would
have commenced on the date of such failure) in each case at the applicable rate
of interest for such Loans provided for herein (but excluding loss of margin)
over (ii) the amount of interest (as reasonably determined by such Lender) which
would have accrued to such Lender on such amount by placing such amount on
deposit for a comparable period with leading banks in the interbank eurodollar
market. Each Lender claiming any payment pursuant to this subsection 2.16 shall
do so by giving notice thereof to the Borrower and the Administrative Agent
(showing calculation of the amount claimed in reasonable detail) within 60
Business Days after a failure to borrow, convert or continue Eurodollar Loans,
or to prepay, after notice or after a prepayment of Eurodollar Loans on a day
which is not the last day of an Interest Period therefor. This covenant shall
survive the termination of this Agreement and the payment of the Loans and all
other amounts payable hereunder.

         2.17 Replacement of Lenders. If at any time (a) the Borrower becomes
obligated to pay additional amounts described in subsections 2.13, 2.14 or 2.15
as a result of any condition described in such subsections, (b) any Lender
ceases to make Eurodollar Loans pursuant to subsection 2.13, (c) any Lender
becomes insolvent and its assets become subject to a receiver, liquidator,
trustee, custodian or other Person having similar powers or (d) any Lender
becomes a "Nonconsenting Lender" (hereinafter defined), then the Borrower may,
on five (5) Business Days' prior written notice to the Administrative Agent and
such Lender, replace such Lender by causing such Lender to (and such Lender
shall) assign pursuant to subsection 10.6 all of its rights and obligations
under this Agreement to a Lender or other entity selected by the Borrower and
acceptable to the Administrative Agent for a purchase price equal to the
outstanding principal amount of such Lender's Loans and all accrued interest and
fees and other amounts payable hereunder (including amounts payable under
subsection 2.16 as though such Loans were being paid instead of being
purchased); provided that (i) the Borrower shall have no right to replace the
Administrative Agent, (ii) neither the Administrative Agent nor any Lender shall
have any obligation to the Borrower to find a replacement Lender, (iii) in the
event of a replacement of a Nonconsenting Lender or a Lender to which the
Borrower becomes obligated to pay additional amounts under one of the
subsections described in clause (a) above, in order for the Borrower to be
entitled to replace such a Lender, such replacement must take place no later
than 180 days after (A) the date the Nonconsenting Lender shall have notified
the Borrower and the Administrative Agent of its failure to agree to any
requested consent, waiver or amendment or (B) the Lender shall have demanded
payment of additional amounts under one of the subsections described in clause
(a) above, as the case may be, and (iv) in no event shall the Lender hereby
replaced be required to pay or surrender to its replacement Lender or other
entity any of the fees received by such Lender hereby replaced pursuant to this
Agreement. In the case of a replacement of a Lender to which the Borrower
becomes obligated to pay additional amounts pursuant to this subsection 2.17,
the Borrower shall pay such additional amounts to such Lender prior to such
Lender being replaced and the payment of such additional amounts shall be a
condition to the replacement of such Lender. In the event that (x) the Borrower
or the Administrative Agent has requested the Lenders to consent to a departure
or waiver of any provisions of the Credit Documents or to agree to any amendment
thereto or consent to the Extension Option, (y) the consent, waiver or amendment
in question requires the agreement of all Lenders in accordance with the terms
of subsection 10.1 or relates to a request to exercise the Extension Option
under subsection 2.5(a) and (z) the Required Lenders have agreed to such
consent, waiver or amendment, then any Lender who does not agree to such
consent, waiver or amendment shall be deemed a "Nonconsenting Lender."

         2.18 Certain Fees. The Borrower agrees to pay to the Administrative
Agent, for its own account, the non-refundable fees at the times and in the
amounts as set forth in that certain fee letter between the Administrative Agent
and the Borrower dated on or about March 1, 2000

         2.19 Certain Rules Relating to the Payment of Additional Amounts.

            (a) Upon the request, and at the expense, of the Borrower, each
         Lender to which the Borrower is required to pay any additional amount
         pursuant to subsection 2.14 or 2.15 shall reasonably afford the
         Borrower the opportunity to

                                       39
<PAGE>

         contest, and reasonably cooperate with the Borrower in contesting, the
         imposition of any Non-Excluded Taxes or other amounts giving rise to
         such payment; provided that (i) such Lender shall not be required to
         afford the Borrower the opportunity to so contest unless the Borrower
         shall have confirmed in writing to such Lender its obligation to pay
         such amounts pursuant to this Agreement and (ii) the Borrower shall
         reimburse such Lender for its reasonable attorneys' and accountants'
         fees and disbursements incurred in so cooperating with the Borrower in
         contesting the imposition of such Non-Excluded Taxes.

            (b) Each Lender agrees that if it makes any demand for payment under
         subsection 2.14 or 2.15(a), or if any adoption or change of the type
         described in subsection 2.13 shall occur with respect to it, it will
         use reasonable efforts (consistent with its internal policy and legal
         and regulatory restrictions and so long as such efforts would not be
         disadvantageous to it, as determined in its reasonable discretion) to
         designate a different lending office if the making of such a
         designation would allow the Lender to continue to make and maintain
         Eurodollar Loans and would reduce or obviate the need for the Borrower
         to make payments under subsection 2.14 or 2.15(a), or would eliminate
         or reduce the effect of any adoption or change described in subsection
         2.13.

                       SECTION 3. [INTENTIONALLY OMITTED]

                   SECTION 4. REPRESENTATIONS AND WARRANTIES

         To induce the Agents and the Lenders to enter into this Agreement and

         respect to unaudited financial statements, for the absence of footnotes
         and normal year-end audit adjustments) and present fairly in all
         material respects the financial position of the Persons covered thereby
         as at the dates thereof and the results of their operations and cash

the aggregate, reasonably be expected to have a Material Adverse Effect and (d)
is in compliance with all Requirements of Law except to the extent that the
failure to comply therewith could not, in the aggregate, reasonably be expected
to have a Material Adverse Effect.

         4.4 Corporate Power; Authorization; Enforceable Obligations. Each of
Holdings, the Borrower and its Subsidiaries has the corporate power and
authority, and the legal right, to make, deliver and perform the Credit
Documents to which it is a party and, in the case of the Borrower, to borrow
hereunder and has taken all necessary corporate action to authorize the
borrowings on the terms and conditions of this Agreement and to authorize the
execution, delivery and performance of such Credit Documents. No consent or
authorization of, filing with, notice to or other act by or in respect of, any
Governmental Authority or any other Person is required in connection with the
borrowings hereunder or with the execution, delivery, performance, validity or
enforceability of the Credit Documents to which the Borrower and each other
Credit Party is a party, except those referred to in subsections 4.17 and 6.13
and those set forth on Schedule 4.4. This Agreement has been, and each other
Credit Document will be, duly executed and delivered on behalf of the Borrower
and each other Credit Party. This Agreement constitutes, and each other Credit
Document to which it is a party when executed and delivered will constitute, a
legal, valid and binding obligation of each Credit Party thereto enforceable
against each such Credit Party, as the case may be, in accordance with its
terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and other similar laws relating to or affecting
creditors' rights generally, general equitable principles (whether considered in
a proceeding in equity or at law) and an implied covenant of good faith and fair
dealing.

         4.5 No Legal Bar. Except as set forth on Schedule 4.5 or as could not
reasonably be expected to, individually or in the aggregate, have a Material
Adverse Effect, the execution, delivery and performance of each Credit Document,
the borrowing and use of the proceeds of the Loans and the consummation of the
transactions contemplated by the Credit Documents: (a) will not violate any
Requirement of Law or any Contractual Obligation applicable to or binding upon
Holdings, the Borrower or any Subsidiary of the Borrower or any of their
respective properties or assets and (b) will not result in the creation or
imposition of any Lien on any of its properties or assets pursuant to any
Requirement of Law applicable to it or any of its Contractual Obligations,
except for the Liens arising under the Pledge Agreements.

         4.6 No Material Litigation. Except as set forth on Schedule 4.6, no
litigation by, investigation by, or proceeding of or before any arbitrator or
any Governmental Authority is pending or, to the knowledge of the Borrower,
overtly threatened by or against the Borrower or any of its Subsidiaries or
against any of its or their respective properties or revenues with respect to
any Credit Document or any of the transactions contemplated hereby or thereby or
which could reasonably be expected to have a Material Adverse Effect.

         4.7 No Default. Neither Holdings, the Borrower nor any of its
Subsidiaries is in default under or with respect to any of its Contractual
Obligations in any respect which could reasonably be expected to have a Material
Adverse Effect. No Default or Event of Default has occurred and is continuing.

         4.8 Ownership of Property; Liens. Each of Holdings, the Borrower and
its Subsidiaries (i) has good record and insurable title in fee simple to, or a
valid leasehold interest in, all its material real property, (ii) has good title
to, or a valid leasehold interest in, all its other material property and (iii)
none of such property in clauses (i) and (ii) is or shall be subject to any Lien
except as permitted by subsection 7.3.

         4.9 Intellectual Property. Holdings, the Borrower and each of its
Subsidiaries owns, or is licensed to use, all trademarks, tradenames,
copyrights, technology, know-how and processes necessary for the conduct of its
business as currently conducted except for those the failure to own or license
which could not reasonably be expected to have a Material Adverse Effect (the
"Intellectual Property"). To the best of the Borrower's knowledge, and except as
set forth on Schedule 4.9, no claim has been asserted and is pending by any
Person challenging or questioning the use of any such Intellectual Property or
the validity or effectiveness of any such Intellectual Property, nor does the
Borrower know of any valid basis for any such claim which could reasonably be
expected to have a Material Adverse Effect. The use of such Intellectual
Property by Holdings, the Borrower and its Subsidiaries does not infringe on the
rights of any Person, except for such claims and infringements that, in the
aggregate, could not reasonably be expected to have a Material Adverse Effect.

         4.10 Taxes. Except as set forth on Schedule 4.10, each of Holdings, the
Borrower and its Subsidiaries has filed or caused to be filed all material tax
returns which, to the knowledge of the Borrower, are required to be filed and
has paid all taxes shown to be due and payable on said returns or on any
assessments made against it or any of its property and all other material taxes,
fees or other charges imposed on it or any of its property by any Governmental

                                       42
<PAGE>

Authority (other than any the amount or validity of which are currently being
contested in good faith by appropriate proceedings and with respect to which
reserves in conformity with GAAP have been provided on the books of Holdings,
the Borrower or its Subsidiaries, as the case may be); no tax Lien has been
filed, and, to the knowledge of the Borrower, no claim is being asserted, with
respect to any such tax, fee or other charge.

         4.11 Federal Regulations. No part of the proceeds of any Loans will be
used for "purchasing" or "carrying" any "margin stock" within the respective
meanings of each of the quoted terms under Regulation U of the Board of
Governors of the Federal Reserve System as now and from time to time hereafter
in effect.

         4.12 ERISA. The Borrower has provided to the Agents a true and correct
copy of all agreements, arrangements and understandings relating to the transfer
of Plans from the Seller to the Borrower (the "Transfer Agreements"). The
Transfer Agreements are in full force and effect and have not been waived or
modified without the consent of the Agents (which shall not be unreasonably
withheld) except to the extent any such waiver or modification, singly or in the
aggregate, could not be reasonably expected to have a Material Adverse Effect.
Except as could not reasonably be expected, individually or in the aggregate, to
have a Material Adverse Effect, no Reportable Event has occurred with respect to
any Single Employer Plan, all contributions required to be made with respect to
a Plan have been timely made; none of the Borrower or any of its Subsidiaries
nor any Commonly Controlled Entity has incurred any material liability to or on
account of a Plan pursuant to Section 409, 502(i), 502(1), 515, 4062, 4063,
4064, 4069, 4201, 4204 or 4212 of ERISA or Section 401(a)(29), 4971, 4975 or
4980 of the Code or expects to incur any liability (including any indirect,
contingent or secondary liability) under any of the foregoing Sections with
respect to any Plan; no termination or, or institution of proceedings to
terminate or appoint a trustee to administer, a Single Employer Plan has
occurred; and each Plan has complied in all material respects with the
applicable provisions of ERISA and the Code (except that with respect to any
Multiemployer Plan, such representation is deemed made only to the knowledge of
the Borrower). No "accumulated funding deficiency" (within the meaning of
Section 412 of the Code or Section 302 of ERISA), extension of any amortization
period (within the meaning of Section 412 of the Code) or Lien in favor of the
PBGC or a Plan has arisen or has occurred during the five-year period prior to
the date on which this representation is made or deemed made with respect to any
Single Employer Plan. As of the last annual valuation date prior to the date on
which this representation is made or deemed made, the fair market value of the
assets available for benefits under each Single Employer Plan did not exceed the
actuarial present value of all accumulated benefit obligations under such Plan
by more than $20,000,000, all as determined in accordance with Statement of
Financial Accounting Standards No. 87. Neither the Borrower nor any Commonly
Controlled Entity has had a complete or partial withdrawal from any
Multiemployer Plan for which there is any outstanding liability, and neither the
Borrower nor any Commonly Controlled Entity would become subject to any
liability under ERISA if the Borrower or any such Commonly Controlled Entity
were to withdraw completely from all Multiemployer Plans as of the valuation
date most closely preceding the date on which this representation is made or
deemed made in an amount which would be reasonably likely to have a Material
Adverse Effect. To the best knowledge of the Borrower, no such Multiemployer
Plan is in Reorganization or Insolvent.

         4.13 Investment Company Act; Other Regulations. None of the Borrower or
any of its Subsidiaries is an "investment company," or a company "controlled" by
an "investment company," within the meaning of the Investment Company Act of
1940, as amended. None of the Borrower or any of its subsidiaries is not subject
to regulation under any Federal or State statute or regulation (other than
Regulation X of the Board of Governors of the Federal Reserve System) which
limits its ability to incur Indebtedness.

         4.14 Subsidiaries. The Subsidiaries of the Borrower and their
respective jurisdictions of incorporation shall be as set forth on Schedule
4.14.

         4.15 Purpose of Loans. The proceeds of the Loans shall be used by the
Borrower (i) to pay the cash portion of the purchase price for the Acquired
Company pursuant to the Acquisition Documents, (ii) to pay fees and expenses
related to the preparation and negotiation of the Acquisition Documents, this
Agreement and the other Credit Documents and (iii) for general corporate and
working capital purposes in the ordinary course of business of the Borrower and
its Subsidiaries, including, without limitation, the making of Investments
permitted under subsection 7.9.

         4.16 Environmental Matters. Except insofar as any exception to any of
the following, or any aggregation of such exceptions, is not reasonably likely
to result in a Material Adverse Effect:

         Holdings, by the Borrower or any of its Subsidiaries (the "Properties")
         do not contain, and have not previously contained, any Materials of
         Environmental Concern in amounts or concentrations which (i) constitute
         or constituted a violation of, or (ii) could reasonably be expected to
         give rise to liability under, any applicable Environmental Law.

            (b) None of Holdings, the Borrower nor any of its Subsidiaries has
         received any written notice of violation, alleged violation,
         non-compliance, liability or potential liability regarding
         environmental matters or compliance with Environmental Laws with regard
         to any of the Properties or the Business, nor does the Borrower have
         knowledge or reason to believe that any such notice will be received or
         is being threatened.

            (c) Materials of Environmental Concern have not been transported or
         disposed of from the Properties in violation of, or in a manner or to a
         location which could reasonably be expected to give rise to liability
         under, any applicable Environmental Law, nor have any Materials of
         Environmental Concern been generated, treated, stored or disposed of
         at, on or under any of the Properties in violation of, or in a manner
         that could reasonably be expected to give rise to liability under, any
         applicable Environmental Law.

            (d) No judicial proceeding or governmental or administrative action
         is pending or, to the knowledge of the Borrower, threatened, under any

                                       44
<PAGE>

         Environmental Law to which Holdings, the Borrower or any Subsidiary is
         or, to the knowledge of the Borrower, will be named as a party or with
         respect to the Properties or the Business, nor are there any consent
         decrees or other decrees, consent orders, administrative orders or
         other orders, or other administrative or judicial requirements
         outstanding under any Environmental Law with respect to the Properties
         or the Business.

            (e) There has been no release or threat of release of Materials of
         Environmental Concern at or from the Properties, or arising from or
         related to the operations of Holdings, the Borrower or any Subsidiary
         in connection with the Properties or otherwise in connection with the
         Business, in violation of or in amounts or in a manner that could
         reasonably give rise to liability under any applicable Environmental
         Laws.

            (f) The Properties and all operations at the Properties are in
         compliance, and have in the last 3 years been in compliance, in all
         material respects with all applicable Environmental Laws, and there is
         no contamination at, under or about the Properties or violation of any
         applicable Environmental Law with respect to the Properties or the
         business operated by Holdings, the Borrower or any of its Subsidiaries
         (the "Business") which could materially interfere with the continued
         operation of the Properties or materially impair the fair saleable
         value thereof.

            (g) Holdings, the Borrower and its Subsidiaries hold and are in
         compliance with all Environmental Permits necessary for their
         operations.

         4.17 Collateral Documents. Upon execution and delivery thereof by the
parties thereto, each Pledge Agreement will be effective to create in favor of
the Administrative Agent, for the ratable benefit of the Lenders, a legal, valid
and enforceable security interest in the pledged stock described therein and,
when stock certificates representing or constituting the pledged stock described
therein are delivered to the Administrative Agent, together with undated stock
powers executed in blank therefor, such security interest shall, subject to the
existence of Permitted Liens, constitute a perfected first lien on, and security
interest in, all right, title and interest of the pledgor party thereto in the
pledged stock described therein.

         4.18 Accuracy and Completeness of Information. No fact is known to
Holdings, the Borrower or any of its Subsidiaries which has had or could
reasonably be expected to have a Material Adverse Effect, which has not been
disclosed to the Lenders by Holdings, the Borrower or its Subsidiaries in
writing prior to the date hereof. Neither Holdings, the Borrower nor any
Subsidiary of the Borrower is aware of any material liability of the Borrower or
any of its Subsidiaries which is not fully disclosed in the most recent
financial statements delivered to the Agents and Lenders pursuant to subsections
4.1 and 6.1 hereto.

         4.19 Labor Matters. There are no strikes pending or, to the Borrower's
knowledge, overtly threatened against Holdings, the Borrower or any of its
Subsidiaries which, individually or in the aggregate, could reasonably be
expected to have a Material Adverse Effect.

                                       45
<PAGE>

The hours worked and payments made to employees of Holdings, the Borrower and
each of its Subsidiaries (and their predecessors) have not been in violation of
the Fair Labor Standards Act or any other applicable Requirement of Law, except
to the extent such violations could not, or in the aggregate, be reasonably
expected to have a Material Adverse Effect.

         4.20 Acquisition. The Acquisition Documents listed on Schedule 4.20
attached hereto constitute all of the material agreements, instruments and
undertakings to which Holdings, the Borrower or any of its Subsidiaries is bound
or by which such Person or any of its property or assets is bound or affected
relating to, or arising out of, the Acquisition (including, without limitation,
any agreements, instruments or undertakings assumed pursuant to the Acquisition
Documents). None of such material agreements, instruments or undertakings have
been amended, supplemented or otherwise modified, and all such material
agreements, instruments and undertakings are in full force and effect. As of the
Closing Date, the Borrower is not in default under any of the Acquisition
Documents and, to the best of Borrower's knowledge, no other party to any
Acquisition Document is in default thereunder. Upon the funding of the initial
Loan under this Agreement on the Closing Date, the Acquisition shall have been
consummated in accordance with the material terms of the Acquisition Documents.
As of the Closing Date, the representations and warranties of the Borrower
contained in the Acquisition Documents are true and correct in all material
respects.

         Immaterial Subsidiary or Foreign Subsidiary of the Borrower shall be
         required to execute a Subsidiary Guarantee or Subsidiary Pledge
         Agreement, and no more than 65% of the capital stock of or equity
         interests in any Foreign Subsidiary of the Borrower or any of its
         Subsidiaries if more than 65% of the assets of such Subsidiary are
         securities of foreign companies (such determination to be made on the
         basis of fair market value), shall be required to be pledged hereunder.

                                       46

         execution, delivery and performance by the Credit Parties, and the
         validity and enforceability against the Credit Parties, of the Credit
         Documents to which any of them is a party, shall have been obtained or
         made, and such consents, authorizations and filings shall be in full
         force and effect, except such consents, authorizations and filings, the
         failure to obtain which would not have a Material Adverse Effect. In
         addition, all governmental, shareholder and third party consents,
         authorizations, approvals and filings, if any, necessary or, in the
         reasonable discretion of the Agents, advisable in connection with the

         impose materially adverse conditions on the Acquisition or the
         financing contemplated hereby.

            (e) Insurance. The Lenders shall have received (i) a reasonably
         satisfactory schedule describing all insurance maintained by the
         Borrower and its Subsidiaries pursuant to subsection 6.5, and (ii)
         binders (or other customary evidence as to the obtaining and
         maintenance by the Borrower and its Subsidiaries of such insurance) for
         each policy set forth on such schedule insuring against casualty and
         other usual and customary risks.

            (f) Litigation. On the Closing Date, there shall not exist actions,
         suits or proceedings pending or threatened against any Credit Party or
         any order, decree, judgment, ruling or injunction (a) with respect to
         this Agreement or any other Credit Document or any Acquisition Document
         or the transactions contemplated hereby or thereby, (b) which the
         Agents or the Required Lenders shall determine could reasonably be
         expected to have a Material Adverse Effect or (c) which restrains the
         consummation of the Acquisition in the manner contemplated by the

     believe that the Borrower failed to comply with the provisions of
     subsection 7.1, except as specified in such certificate;

         (b) concurrently with the delivery of the financial statements referred
     to in subsection 6.1, a certificate of a Responsible Officer stating that,

     subsection 6.10 with respect thereto) and (ii) such Officer has obtained no
     knowledge of any Default or Event of Default except as specified in such

judgment of the Borrower or such Subsidiary, as the case may be, it is in its
best economic interest not to preserve and maintain such rights, privileges or
franchises, and (ii) such failure to preserve and maintain such privileges,
rights or franchises would not materially adversely affect the rights of the
Lenders hereunder or the value of the Collateral, and except as otherwise
permitted pursuant to subsection 7.5; and (d) comply with all Contractual
Obligations and Requirements of Law except to the extent that failure to comply
therewith could not, in the aggregate, be reasonably expected to have a Material
Adverse Effect.

         Subsidiaries shall generally not, or shall be unable to, or shall admit
         in writing its inability to, pay its debts as they become due;

            (g) (i) Any Person shall engage in any "prohibited transaction" (as

         Holdings, the Borrower or any of its Subsidiaries involving in the
         aggregate a liability (not paid or fully covered by insurance (which

         $7,500,000 or more, and all such judgments or decrees shall not have
         been vacated, discharged, stayed or bonded pending appeal within 60
         days from the entry thereof;

            (i) (i) Any of the Pledge Agreements shall cease, for any reason, to
         be in full force and effect (unless released by the Administrative
         Agent at the direction of the requisite Lenders or as otherwise
         permitted under this Agreement or the other Credit Documents), or the
         Borrower or any other Credit Party which is a party to any of the
         Pledge Agreements shall so assert or (ii) the Lien created

                                       68
<PAGE>

         by any of the Pledge Agreements shall cease to be enforceable and of
         the same effect and priority purported to be created thereby (and, if
         such invalidity is such so as to be amenable to cure without materially
         disadvantaging the position of the Administrative Agent and the
         Lenders, as the case may be, as secured parties thereunder, the Credit
         Party shall have failed to cure such invalidity within 30 days after
         notice from the Administrative Agent);

            (j) The Guarantee Obligation of any Credit Party under the Credit
         Documents shall be held in any judicial proceeding to be unenforceable
         or invalid or shall cease for any reason to be in full force and effect
         or any Credit Party or any Person acting on behalf of any Credit Party,
         shall deny or disaffirm its obligations under such Guarantee
         Obligation;

            (k) There shall have occurred a Change in Control; or

            (l) An "Event of Default" as defined in the Facility A Credit
         Agreement and/or the Facility B Credit Agreement shall have occurred
         and be continuing;

then, and in any such event, (A) if such event is an Event of Default specified
in clause (i) or (ii) of paragraph (f) of this Section above with respect to the
Borrower, automatically the Commitments shall immediately terminate and the
Loans hereunder (with accrued interest thereon) and all other amounts owing
under this Agreement and the Notes shall immediately become due and payable, and

and (ii) with the consent of the Required Lenders, the Administrative Agent may,
or upon the request of the Required Lenders, the Administrative Agent shall, by

and payable.

         EXCEPT AS EXPRESSLY PROVIDED ABOVE IN THIS SECTION, PRESENTMENT,
DEMAND, PROTEST AND ALL OTHER NOTICES OF ANY KIND ARE HEREBY EXPRESSLY WAIVED.

                      SECTION 9. THE AGENTS; THE ARRANGERS

         9.1 Appointment. Each Lender hereby irrevocably designates and appoints
each of the Agents as the agent of such Lender under this Agreement and the
other Credit Documents, and each such Lender irrevocably authorizes each of the
Agents, in such capacity, to take such action on its behalf under the provisions
of this Agreement and the other Credit Documents and to exercise such powers and
perform such duties as are expressly delegated to such Agent by the terms of
this Agreement and the other Credit Documents, together with such other powers
as are reasonably incidental thereto. Notwithstanding any provision to the
contrary

                                       69
<PAGE>

elsewhere in this Agreement, none of the Agents shall have any duties or
responsibilities, except those expressly set forth herein, or any fiduciary
relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Credit Document or otherwise exist against any of the
Agents.

         9.2 Delegation of Duties. The Agents may execute any of their duties
under this Agreement and the other Credit Documents by or through agents or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. None of the Agents shall be responsible for
the negligence or misconduct of any agents or attorneys in-fact selected by it
with reasonable care.

         9.3 Exculpatory Provisions. Neither any of the Agents nor any of their
officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be
(i) liable for any action lawfully taken or omitted to be taken by it or such
Person under or in connection with this Agreement or any other Credit Document
(except for its or such Person's own gross negligence or willful misconduct) or
(ii) responsible in any manner to any of the Lenders for any recitals,
statements, representations or warranties made by the Borrower or any officer
thereof contained in this Agreement or any other Credit Document or in any
certificate, report, statement or other document referred to or provided for in,
or received by such Agent under or in connection with, this Agreement or any
other Credit Document or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Credit Document or
for any failure of the Borrower to perform its obligations hereunder or
thereunder. None of the Agents shall be under any obligation to any Lender to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement or any other Credit
Document, or to inspect the properties, books or records of the Borrower.

         9.4 Reliance by Agents. The Agents shall be entitled to rely, and shall
be fully protected in relying, upon any Note, writing, resolution, notice,
consent, certificate, affidavit, letter, telecopy, telex or teletype message,
statement, order or other document or conversation believed by it to be genuine
and correct and to have been signed, sent or made by the proper Person or
Persons and upon advice and statements of legal counsel (including, without
limitation, counsel to the Borrower), independent accountants and other experts
selected by such Agent. The Agents may deem and treat the payee of any Note as
the owner thereof for all purposes unless a written notice of assignment,
negotiation or transfer thereof shall have been filed with such Agent. Except as
expressly provided in this Agreement, the Agents shall be fully justified in
failing or refusing to take any action under this Agreement or any other Credit
Document unless it shall first receive such advice or concurrence of the
Required Lenders as it deems appropriate or it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action. The
Agents shall in all cases be fully protected in acting, or in refraining from
acting, under this Agreement and the other Credit Documents in accordance with a
request of the Required Lenders, and such request and any action taken or
failure to act pursuant thereto shall be binding upon all the Lenders and all
future holders of the Loans.

         9.5 Notice of Default. No Agent shall be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default hereunder unless
such Agent has received

                                       70
<PAGE>

notice from a Lender or the Borrower referring to this Agreement, describing
such Default or Event of Default and stating that such notice is a "notice of
default". In the event that any Agent receives such a notice, such Agent shall
give notice thereof to the Lenders. Each Agent shall take such action with
respect to such Default or Event of Default as shall be reasonably directed by
the Required Lenders; provided that unless and until such Agent shall have
received such directions, such Agent may (but shall not be obligated to) take
such action, or refrain from taking such action, with respect to such Default or
Event of Default as it shall deem advisable in the best interests of the
Lenders.

         9.6 Non-Reliance on Agents and Other Lenders. Each Lender expressly
acknowledges that neither any of the Agents nor any of their officers,
directors, employees, agents, attorneys-in-fact or Affiliates has made any
representations or warranties to it and that no act by any of the Agents
hereafter taken, including any review of the affairs of the Borrower, shall be
deemed to constitute any representation or warranty by any of the Agents to any
Lender. Each Lender represents to each of the Agents that it has, independently
and without reliance upon any of the Agents or any other Lender, and based on
such documents and information as it has deemed appropriate, made its own
appraisal of and investigation into the business, operations, property,
financial and other condition and credit worthiness of the Borrower and made its
own decision to make its Loans hereunder and enter into this Agreement. Each
Lender also represents that it will, independently and without reliance upon any
of the Agents or any other Lender, and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit
analysis, appraisals and decisions in taking or not taking action under this
Agreement and the other Credit Documents, and to make such investigation as it
deems necessary to inform itself as to the business, operations, property,
financial and other condition and creditworthiness of the Borrower. Except for
notices, reports and other documents expressly required to be furnished to the
Lenders by any of the Agents hereunder (or copies of which have been provided to
the Administrative Agent pursuant to this Agreement), none of the Agents shall
have any duty or responsibility to provide any Lender with any credit or other
information concerning the business, operations, property, condition (financial
or otherwise), prospects or creditworthiness of any Credit Party which may come
into the possession of such Agent or any of its officers, directors, employees,
agents, attorneys-in-fact or Affiliates.

         9.7 Indemnification. The Lenders agree to indemnify each of the Agents
in their respective capacities as such (to the extent not reimbursed by the
Borrower and without limiting the obligation of the Borrower to do so), ratably
according to their respective Commitment Percentages with respect to all Loans
in effect on the date on which indemnification is sought, from and against any
and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind whatsoever which
may at any time (including, without limitation, at any time following the
payment of the Loans) be imposed on, incurred by or asserted against any of the
Agents in any way relating to or arising out of, the Commitments, this
Agreement, any of the other Credit Documents or any documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or thereby
or any action taken or omitted by any of the Agents under or in connection with
any of the foregoing provided that no Lender shall be liable for the payment of
any portion of such liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements resulting from such
Agent's gross negligence or willful misconduct. The

                                       71
<PAGE>

agreements in this subsection shall survive the payment of the Loans and all
other amounts payable hereunder.

         9.8 Agents, in Their Individual Capacities. The Agents and their
respective Affiliates may make loans to, accept deposits from and generally
engage in any kind of business with the Borrower as though the Agents were not
acting in such capacities hereunder and under the other Credit Documents. With
respect to the Loans made or renewed by it and any Note issued to it or Loan
Account maintained by it, each Agent shall have the same rights and powers under
this Agreement and the other Credit Documents as any Lender and may exercise the
same as though it were not an Agent, and the terms "Lender" and "Lenders" shall
include the Agents in their individual capacities.

         9.9 Successor Administrative Agent, Syndication Agent and Documentation
Agent. The Administrative Agent may resign as Administrative Agent upon 30 days'
notice to the Lenders. If the Administrative Agent resigns under this Agreement,
the Required Lenders shall appoint from among the Lenders a successor
administrative agent for the Lenders, which successor administrative agent
shall, unless a Default or Event of Default shall have occurred and be
continuing, be approved by the Borrower. If no successor administrative agent is
appointed prior to the effective date of the resignation of the Administrative
Agent, the Administrative Agent may appoint, after consulting with the Lenders
and the Borrower, a successor administrative agent from among the Lenders. Upon
the acceptance of its appointment as successor administrative agent hereunder,
such successor administrative agent shall succeed to all the rights, powers and
duties of the retiring Administrative Agent and the term "Administrative Agent"
shall mean such successor administrative agent and the retiring Administrative
Agent's appointment, powers and duties as Administrative Agent shall be
terminated. After any retiring Administrative Agent's resignation hereunder as
Administrative Agent, the provisions of this Section 9 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement. If no successor administrative agent
has accepted appointment as Administrative Agent by the date which is 30 days
following a retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become effective
and the Lenders shall perform all of the duties of the Administrative Agent
hereunder until such time, if any, as the Required Lenders appoint a successor
administrative agent as provided for above. Similarly, the Syndication Agent
and/or the Documentation Agent may resign as Syndication Agent and/or
Documentation Agent, as the case may be, upon 30 days' notice to the Lenders.
The procedure for replacement and effective date of resignation for the
Syndication Agent and the Documentation Agent shall be identical to that
provided above for the Administrative Agent.

         9.10 The Arrangers and the Managing Agents. Except as expressly set
forth herein, each of the Arrangers and the Managing Agents, in their respective
capacities as such, shall have no duties or responsibilities, and shall incur no
liabilities, under this Agreement or the other Credit Documents.

                                       72

                           SECTION 10. MISCELLANEOUS

         10.1 Amendments and Waivers. Neither this Agreement nor any other
Credit Document, nor any terms hereof or thereof may be amended, supplemented,
waived or modified except in accordance with the provisions of this subsection.
The Required Lenders may, or, with the written consent of the Required Lenders,
the Administrative Agent may, from time to time, (a) enter into with the
Borrower written amendments, supplements or modifications hereto and to the
other Credit Documents for the purpose of adding any provisions to this
Agreement or the other Credit Documents or changing in any manner the rights of
the Lenders or of the Borrower hereunder or thereunder or (b) waive, on such
terms and conditions as the Required Lenders or the Administrative Agent, as the
case may be, may specify in such instrument, any of the requirements of this
Agreement or the other Credit Documents or any Default or Event of Default and
its consequences; provided, however, that no such waiver and no such amendment,
supplement or modification shall (i) reduce the amount or extend any scheduled
date of maturity of any Loan or reduce the stated rate or amount of any interest
or fee payable hereunder or extend the scheduled date of any payment thereof, in
each case without the consent of each Lender affected thereby, or increase the
commitment of any Lender or extend the expiry of the commitment of any Lender
without the consent of such Lender, (ii) amend, modify or waive the definition
of Required Lenders, or consent to the assignment or transfer by the Borrower of
any of its rights and obligations under this Agreement and the other Credit
Documents, in each case without the written consent of all the Lenders, (iii)
release all or substantially all of the Collateral or release all or
substantially all of the Credit Parties from their Guarantee Obligations under
the Credit Documents without the consent of all Lenders, (iv) amend, modify or
waive any provision of Section 9 without the written consent of the then Agents,
or (v) amend, modify or waive any provision of this Agreement or any other
Credit Document which would directly and adversely affect the Arrangers or the
Agents without the written consent of the Arrangers or the Agents, as the case
may be. In addition to the foregoing, (A) no amendment, modification,
termination or waiver of any provision of subsection 2.5, subsection 2.6 or
subsection 2.12 which has the effect of changing any interim scheduled payments,
voluntary or mandatory prepayments, the application of any scheduled payment or
voluntary or mandatory prepayment, the application of proceeds of any Collateral
or any Commitment reductions applicable to any Class (an "Affected Class") in a
manner that disproportionately disadvantages such Class relative to the other
Class shall be effective without the written concurrence of the Requisite Class
Lenders of the Affected Class (it being understood and agreed that any
amendment, modification, termination or waiver of any provision which only
postpones or reduces any interim scheduled payment, voluntary or mandatory
prepayment or Commitment reduction from those set forth in subsection 2.6 with
respect to only one Class shall be deemed to not disproportionately disadvantage
the other Class and, therefore, shall not require the consent of Requisite Class
Lenders of such other Class), (B) no amendment, modification, termination or
waiver of any provision of any Guarantee or Pledge Agreement shall be effective
without the written concurrence of the Requisite Class Lenders for each Class
and (C) no amendment, modification or waiver with respect to any provision of
this subsection 10.1 or to the definition of "Requisite Class Lenders" shall be
effective without the written concurrence of all Lenders, all Facility A Lenders
and all Facility B Lenders. Any such waiver and any such amendment, supplement
or modification shall apply equally to each of the Lenders and shall be binding
upon the Borrower, the Lenders, the Agents and all future holders

                                       73
<PAGE>

of the Loans. In the case of any waiver, the Borrower, the Lenders and the
Agents shall be restored to their former positions and rights hereunder and
under the other Credit Documents, and any Default or Event of Default waived
shall be deemed to be cured and not continuing; no such waiver shall extend to
any subsequent or other Default or Event of Default or impair any right
consequent thereon.

         10.2 Notices. All notices, requests and demands to or upon the

consummation or administration of any of the transactions contemplated by, or
any amendment, supplement or modification of, or any waiver or consent under or
in respect of, this Agreement, the other Credit Documents and any such other

Acquisition, including, without limitation, any of the foregoing relating to the
violation of, noncompliance with or liability under, any Environmental Law
applicable to the operations of the Borrower, any of its Subsidiaries or any of
the Properties (all the foregoing in this clause (d), collectively, the
"indemnified liabilities"), it being understood that the Borrower shall have an
obligation hereunder to any Lender, Arranger or Agent with respect to any
indemnified liabilities incurred by any Agent, Arranger or Lender as a result of
any Materials of Environmental Concern that are first manufactured, emitted,
generated, treated, released, spilled, stored or disposed of on, at or from any
Property or any violation of any Environmental Law, which in any case first
occurs on or with respect to such Property (i) after the Property is transferred
to any Agent, Arranger or Lender or their successors or assigns by foreclosure
sale, deed in lieu of foreclosure, or similar transfer or, following such
transfer, (ii) in connection with, but prior to, the sale, leasing or other
transfer of such Property by such Agent, Arranger or Lender or their successors
or assigns to one or more third parties; provided, however, that the Borrower
shall have no obligation hereunder to any Agent, Arranger or Lender with respect
to otherwise indemnified liabilities arising from the gross negligence or
willful misconduct of such Agent, Arranger or Lender, or with respect to
otherwise indemnified liabilities following the sale, leasing or other transfer
of such Property to one or more third parties. The agreements in this subsection
shall survive repayment of the Loans and all other amounts payable hereunder.

         10.6 Successors and Assigns; Participation and Assignments.

            (a) This Agreement shall be binding upon and inure to the benefit of
         the Borrower, the Lenders, the Agents and their respective successors
         and assigns, except that the Borrower may not assign or transfer any of
         its rights or obligations under this Agreement without the prior
         written consent of each Lender.

            (b) Any Lender may, in the ordinary course of its business and in
         accordance with applicable law, at any time sell to one or more banks
         or other entities ("Participants") participating interests in any Loan
         owing to such Lender or any other interest of such Lender hereunder and
         under the other Credit Documents. In the event of any such sale by a
         Lender of a participating interest to a Participant, such Lender's
         obligations

                                       77
<PAGE>

         under this Agreement to the other parties to this Agreement shall
         remain unchanged, such Lender shall remain solely responsible for the
         performance thereof, such Lender shall remain the holder of any such
         Loan for all purposes under this Agreement and the other Credit
         Documents, and the Borrower and the Agents shall continue to deal
         solely and directly with such Lender in connection with such Lender's
         rights and obligations under this Agreement and the other Credit
         Documents. No Lender shall be entitled to create in favor of any
         Participant, in the participation agreement pursuant to which such
         Participant's participating interest shall be created or otherwise, any
         right to vote on, consent to or approve any matter relating to this
         Agreement or any other Credit Document except for those specified in
         clauses (i), (ii) and (iii) of the proviso to subsection 10.1. The
         Borrower agrees that if amounts outstanding under this Agreement are
         due or unpaid, or shall have been declared or shall have become due and
         payable upon the occurrence of an Event of Default, each Participant
         shall, to the maximum extent permitted by applicable law, be deemed to
         have the right of setoff in respect of its participating interest in
         amounts owing under this Agreement to the same extent as if the amount
         of its participating interest were owing directly to it as a Lender
         under this Agreement; provided that, in purchasing such participating
         interest, such Participant shall be deemed to have agreed to share with
         the Lenders the proceeds thereof as provided in subsection 10.7(a) as
         fully as if it were a Lender hereunder. The Borrower also agrees that
         each Participant shall be entitled to the benefits of subsections 2.14,
         2.15 and 2.16 with respect to its participation in the Commitments and
         the Loans outstanding from time to time as if it was a Lender; provided
         that in the case of subsection 2.15, such Participant shall have
         complied with the requirements of said subsection; provided, further,
         that no Participant shall be entitled to receive any greater amount
         pursuant to any such subsection than the transferor Lender would have
         been entitled to receive in respect of the amount of the participation
         transferred by such transferor Lender to such Participant had no such
         transfer occurred.

            (c) Any Lender may, in the ordinary course of its business and in
         accordance with applicable law, at any time and from time to time
         assign to any Lender, any affiliate thereof or, in the case of Lender
         that is an investment fund which is regularly engaged in making,
         purchasing or investing in loans or securities (an "Investment Fund"),
         any other such Investment Fund which is under common management with
         such Lender, or, with the consent of the Borrower, the Administrative
         Agent and the Syndication Agent (which in each case shall not be
         unreasonably withheld), to an additional bank, Investment Fund or
         financial institution (an "Assignee") all or any part of its rights and
         obligations under this Agreement and the other Credit Documents
         pursuant to an Assignment and Acceptance, substantially in the form of
         Exhibit F, executed by such Assignee, such assigning Lender (and, in
         the case of an Assignee that is not then a Lender or an affiliate
         thereof, by the Borrower, the Administrative Agent and the Syndication
         Agent) and delivered to the Administrative Agent for its acceptance and
         recording in the Register with a copy to the Syndication Agent,
         provided that, in the case of any such assignment to an additional bank
         or financial institution, (A) either (x) such assignment is of all the
         rights and obligations of the assigning Lender or (y) the sum of the
         aggregate principal amount of the Loans and the aggregate amount of the
         unused Commitments being assigned and, if such assignment is of less
         than all of the rights and obligations of the assigning Lender,

                                       78
<PAGE>

         the sum of the aggregate principal amount of the Loans and the
         aggregate amount of the unused Commitments remaining with the assigning
         Lender are each not less than $5,000,000 (or such lesser amount as may
         be agreed to by the Borrower and the Administrative Agent) and (B) each
         Assignee which is a Non-U.S. Lender shall comply with the provisions of
         clause (A) of subsection 2.15(b) hereof, or, with the prior written
         consent of the Borrower, which shall not be unreasonably withheld, the
         provisions of clause (B) of subsection 2.15(b) hereof (and, in either
         case, with all of the other provisions of subsection 2.15(b) hereof).
         Upon such execution, delivery, acceptance and recording, from and after
         the effective date determined pursuant to such Assignment and
         Acceptance, (x) the Assignee thereunder shall be a party hereto and, to
         the extent provided in such Assignment and Acceptance, have the rights
         and obligations of a Lender hereunder with a Commitment as set forth
         therein and (y) the assigning Lender thereunder shall, to the extent
         provided in such Assignment and Acceptance, be released from its
         obligations under this Agreement (and, in the case of an Assignment and
         Acceptance covering all or the remaining portion of an assigning
         Lender's rights and obligations under this Agreement, such assigning
         Lender shall cease to be a party hereto). Notwithstanding any provision
         of this paragraph (c) and paragraph (f) of this subsection, the consent
         of the Borrower shall not be required for any assignment which occurs
         at any time when any of the events described in clause (f) of Section 8
         shall have occurred and be continuing.

            (d) The Administrative Agent, on behalf of the Borrower, shall
         maintain at the address of the Administrative Agent referred to in
         subsection 10.2 a copy of each Assignment and Acceptance delivered to
         it and a register (the "Register") for the recordation of the names and
         addresses of the Lenders and Commitments of and principal amounts of
         the Loans owing to each Lender from time to time and the registered
         owners of the Obligations evidenced by the Notes and the Loan Accounts.
         The entries in the Register shall be conclusive, in the absence of
         manifest error, and the Borrower, the Administrative Agent and the
         Lenders shall treat each Person whose name is recorded in the Register
         as the owner of a Loan, a Note or other Obligation hereunder as the
         owner thereof for all purposes of this Agreement and the other Credit
         Documents, notwithstanding any notice to the contrary. Any assignment
         of any Loan, Commitment or other obligation evidenced by a Note or a
         Loan Account shall be effective only upon appropriate entries with
         respect thereto being made in the Register, and prior to such
         recordation, all amounts owing to the assignor with respect thereto
         shall remain owing to the assignor. Any assignment or transfer of all
         or part of an Obligation evidenced by a Note shall be registered in the
         Register only upon surrender for registration of assignment or transfer
         of the Note evidencing such Obligation, duly endorsed by (or
         accompanied by a written instrument of assignment or transfer duly
         executed by) the holder thereof, and thereupon one or more new Notes
         shall be issued to the designated Assignee, if requested, and the old
         Note shall be returned by the Administrative Agent to the Borrower
         marked "canceled."

                                       79
<PAGE>

            (e) Upon its receipt of an Assignment and Acceptance executed by an
         assigning Lender and an Assignee (and, in the case of an Assignee that
         is not then a Lender or an affiliate thereof, by the Borrower the
         Administrative Agent and the Syndication Agent ) together with payment
         to the Administrative Agent of a registration and processing fee of
         $3,500 (provided that no such payment shall be required whenever LCPI
         or BOA is the assigning Lender), the Administrative Agent shall (i)
         promptly accept such Assignment and Acceptance and (ii) on the
         effective date determined pursuant thereto record the information
         contained therein in the Register and give notice of such acceptance
         and recordation to the Lenders and the Borrower. Following the
         effective date of any such Assignment and Acceptance, the
         Administrative Agent shall be entitled to update Schedule I hereto to
         reflect the then outstanding Commitments of each Lender whereupon such
         amended Schedule I shall be substituted for the pre-existing Schedule I
         and be deemed a part of this Agreement without any further action or
         consent of any party and the Administrative Agent shall promptly
         deliver a copy of such amended Schedule I to each Lender and the
         Borrower.

            (f) The Borrower authorizes each Lender to disclose to any
         Participant or Assignee (each, a "Transferee") and any prospective
         Transferee, subject to the provisions of subsection 10.15, any and all
         financial information in such Lender's possession concerning the
         Borrower and its Affiliates which has been delivered to such Lender by
         or on behalf of the Borrower pursuant to this Agreement or which has
         been delivered to such Lender by or on behalf of the Borrower in
         connection with such Lender's credit evaluation of the Borrower and its
         Affiliates prior to becoming a party to this Agreement.

            (g) If, pursuant to this subsection 10.6, any interest in this
         Agreement or any Loan is transferred to any Transferee which would be a
         Non-U.S. Lender upon the effectiveness of such transfer, the assigning
         Lender shall cause such Transferee, concurrently with the effectiveness
         of such transfer, (i) to represent to the assigning Lender (for the
         benefit of the assigning Lender, the Administrative Agent and the
         Borrower) that under applicable law and treaties no U.S. Taxes will be
         required to be withheld by the Administrative Agent, the Borrower or
         the assigning Lender with respect to any payments to be made to such
         Transferee in respect of the Loans, (ii) to furnish to the assigning
         Lender (and, in the case of any Assignee registered in the Register,
         the Administrative Agent and the Borrower such Internal Revenue Service
         Forms required to be furnished pursuant to subsection 2.15(b) and (iii)
         to agree (for the benefit of the assigning Lender, the Administrative
         Agent and the Borrower) to be bound by the provisions of subsection
         2.15(b).

            (h) For avoidance of doubt, the parties to this Agreement
         acknowledge that the provisions of this subsection concerning
         assignments of Loans and Notes relate only to absolute assignments and
         that such provisions do not prohibit assignments creating security
         interests, including, without limitation, any pledge

                                       80
<PAGE>

         or assignment by a Lender of any Loan or Note to any Federal Reserve
         Bank in accordance with applicable law.

            (i) Notwithstanding any other provision contained in this Agreement
         or any other Credit Document to the contrary, (x) any Lender may assign
         all or any portion of the Loans held by it to any Federal Reserve Bank
         or the United States Treasury as collateral security pursuant to
         Regulation A of the Federal Reserve Board and any Operating Circular
         issued by such Federal Reserve Bank, provided that any payment in
         respect of such assigned Loans made by the Borrower to or for the
         account of the assigning or pledging Lender in accordance with the
         terms of this Agreement shall satisfy the Borrower's obligations
         hereunder in respect to such assigned Loans to the extent of such
         payments and (y) with the consent of the Administrative Agent (not to
         be unreasonably withheld), any Lender which is an Investment Fund may
         pledge all or any portion of its Loans to its trustee in support of its
         obligations to its trustee. No such assignment shall release the
         assigning Lender from its obligations hereunder.

            10.7 Adjustments; Set-off.

            (a) At any time that an Event of Default has occurred and is
         continuing, if any Lender (a "benefited Lender") shall at any time
         receive any payment of all or part of its Loans owing to it, or
         interest thereon, or receive any collateral in respect thereof (whether
         voluntarily or involuntarily, by set-off, pursuant to events or
         proceedings of the nature referred to in clause (f) of Section 8, or
         otherwise), in a greater proportion than any such payment to or
         collateral received by any other Lender, Facility A Lender or Facility
         B Lender (any such affected Lender, Facility A Lender or Facility B
         Lender, hereinafter, an "Affected Lender"), if any, in respect of the
         Borrower's obligations owing to such other Affected Lender, whether
         under this Agreement, the Facility A Credit Agreement or Facility B
         Credit Agreement, including any interest thereon, such benefited Lender
         shall purchase for cash from each other Affected Lender a participating
         interest in such portion of each such other Affected Lender's Loans
         owing to it, Facility A Loans or Facility A Reimbursement Obligations
         and/or Facility B Loans or Facility B Reimbursement Obligations owing
         to it, or shall provide such other Affected Lenders with the benefits
         of any such collateral, or the proceeds thereof, as shall be necessary
         to cause such benefited Lender to share the excess payment or benefits
         of such collateral or proceeds ratably with each of the Affected
         Lenders; provided, however, that if all or any portion of such excess
         payment or benefits is thereafter recovered from such benefited Lender,
         such purchase shall be rescinded, and the purchase price and benefits
         returned, to the extent of such recovery, but without interest unless
         the benefited Lender is required by court order to pay interest
         thereon, in which case each Lender returning funds to such benefited
         Lender shall pay its pro rata share of such interest.

                                       81

            (b) In addition to any rights and remedies of the Lenders provided
         by law, each Lender shall have the right, without prior notice to the
         Borrower, any such notice being expressly waived by the Borrower to the
         extent permitted by applicable law, upon any amount becoming due and
         payable by the Borrower hereunder (whether at the stated maturity, by
         acceleration or otherwise) to set-off and appropriate and apply against
         such amount any and all deposits (general or special, time or demand,
         provisional or final), in any currency, and any other credits,
         indebtedness or claims, in any currency, in each case whether direct or
         indirect, absolute or contingent, matured or unmatured, at any time
         held or owing by such Lender or any branch or agency thereof to or for
         the credit or the account of the Borrower. Each Lender agrees promptly
         to notify the Borrower and the Administrative Agent after any such
         set-off and application made by such Lender, provided that the failure
         to give such notice shall not affect the validity of such set-off and
         application. Each Lender and Borrower also agree that all proceeds of
         any such set-off shall be subject to the ratable sharing provisions of
         subsections 2.12 and 10.7(a) hereof to the same extent as if an Event
         of Default had occurred and was then continuing.

         10.8 Counterparts. This Agreement may be executed by one or more of the
parties to this Agreement on any number of separate counterparts (including by
facsimile transmission), and all of said counterparts taken together shall be
deemed to constitute one and the same instrument. A set of the copies of this
Agreement signed by all the parties shall be lodged with the Borrower and the
Administrative Agent.

         10.9 Severability. Any provision of this Agreement which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         10.10 Integration. This Agreement and the other Credit Documents
represent the agreement of the Borrower, the Agents and the Lenders with respect
to the subject matter hereof, and there are no promises, undertakings,
representations or warranties by any Agent or any Lender relative to subject
matter hereof not expressly set forth or referred to herein or in the other
Credit Documents.

         10.11 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF
THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

     BE EFFECTED BY MAILING A COPY THEREOF BY REGISTERED OR CERTIFIED MAIL (OR
     ANY SUBSTANTIALLY SIMILAR FORM OF MAIL), POSTAGE PREPAID, TO THE BORROWER
     AT ITS ADDRESS SET FORTH IN SUBSECTION 10.2 OR AT SUCH OTHER ADDRESS OF
     WHICH THE ADMINISTRATIVE AGENT SHALL HAVE BEEN NOTIFIED PURSUANT THERETO;

         (d) AGREES THAT NOTHING HEREIN SHALL AFFECT THE RIGHT TO EFFECT SERVICE

     relationship with or duty to the Borrower arising out of or in connection
     with this Agreement or any of the other Credit Documents, and the
     relationship between any of the Agents and the Lenders, on one hand, and
     the Borrower, on the other hand, in connection herewith or therewith is
     solely that of debtor and creditor; and

         (c) no joint venture is created hereby or by the other Credit Documents
     or otherwise exists by virtue of the transactions contemplated hereby among
     the Lenders or among the Borrower and the Lenders.

         10.14 WAIVERS OF JURY TRIAL. THE BORROWER, THE AGENTS, THE ARRANGERS,
THE LENDERS AND THE OTHER PARTIES HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY
WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT
OR ANY OTHER CREDIT DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

         10.15 Confidentiality. Each Lender agrees to keep confidential all
non-public information provided to it by the Borrower pursuant to this Agreement
that is designated by the Borrower in writing as confidential (excluding any
such information already in the possession of such Lender or provided to such
Lender by a third party not in violation of this Agreement which, in either
case, is not, to the knowledge of such Lender, subject to a confidentiality
agreement); provided that nothing herein shall prevent any Lender from
disclosing any such information (i) to any Agent or any other Lender or any of
its Affiliates, (ii) to any Transferee or prospective Transferee or to any
direct or indirect contractual counterparties in swap agreements or such
contractual counterparties' professional advisors which receives such
information and agrees to be bound by the confidentiality provisions hereof,
(iii) to its employees, directors, agents, attorneys, accountants and other
professional advisors, (iv) upon the request or demand of any Governmental
Authority having jurisdiction over such Lender, (v) in response to any order of
any court or other Governmental Authority or as may otherwise be required
pursuant to any Requirement of Law, (vi) which has been publicly disclosed other

any remedy hereunder.

         10.16 Conversion of Currencies.

            (a) If, for the purpose of obtaining judgment in any court, it is
         necessary to convert a sum owing hereunder in one currency into another
         currency, each party hereto agrees, to the fullest extent that it may
         effectively do so, that the rate of exchange used shall be that at
         which in accordance with normal banking procedures in the relevant
         jurisdiction the first currency could be purchased with such other
         currency on the Business Day immediately preceding the date on which
         final judgment is given.

            (b) The obligations of the Borrower in respect of any sum due to any
         party hereto or any holder of the obligations owing hereunder (the
         "Applicable Creditor") shall, notwithstanding any judgment in a
         currency (the "Judgment Currency") other than the currency in which
         such sum is stated to be due hereunder (the "Agreement Currency"), be
         discharged only to the extent that, on the Business Day following
         receipt by the Applicable Creditor of any sum adjudged to be so due in
         the Judgment Currency, the Applicable Creditor may in accordance with
         normal banking procedures in the relevant jurisdiction purchase the
         Agreement Currency with the Judgment Currency; if the amount of the
         Agreement Currency so purchased is less than the sum originally due to
         the Applicable Creditor in the Agreement Currency, the Borrower agrees,
         as a separate obligation and notwithstanding any such judgment, to
         indemnify the Applicable Creditor against such loss. The obligations of
         the Borrower contained

                                       84
<PAGE>

         in this subsection 10.16 shall survive the termination of this
         Agreement and the payment of all other amounts owing hereunder.

         10.17 Year 2000. The Borrower has reviewed, or will expeditiously
review, its operations and those of its Subsidiaries with a view to assessing
whether its businesses, or the businesses of any of its Subsidiaries, are
experiencing any Year 2000 Problem. The Borrower shall take all actions
necessary and commit adequate resources to assure that its computer-based and
other systems (and those of all of its Subsidiaries) are able to effectively
process data, including dates after January 1, 2000, without experiencing any
Year 2000 Problem that could reasonably be expected to cause a Material Adverse
Effect. At the request of the Required Lenders, the Borrower will provide the
Administrative Agent with assurances and substantiations (including, but not
limited to, the results of internal or external audit reports prepared in the
ordinary course of business) reasonably acceptable to the Administrative Agent
as to the capability of the Borrower and its Subsidiaries to conduct its and
their businesses and operations after January 1, 2000 without experiencing a
Year 2000 Problem causing a Material Adverse Effect. The Borrower represents and
warrants that it has a reasonable basis to believe that no Year 2000 Problem
will cause a Material Adverse Effect.

*    Pricing Grid (except for Debt Ratios) reflects basis points.

**   Notwithstanding the foregoing Pricing Grid, the Applicable Margins and the
     Commitment Fee Rate for the facility for the period following the Closing
     Date through but excluding the Adjustment Date related to the fiscal
     quarter ending as of September 30, 2000 will be no lower in cost to
     Borrower than the pricing level applicable if the Debt Ratio is greater
     than 3.25x but not greater than 3.75x; provided, however, nothing contained
     herein shall limit the effect of any increase in the pricing level on any
     Adjustment Date occurring after the Closing Date if the Debt Ratio exceeds
     3.75x.
