                  Agreement as an objection by such Lender to the requested
                  duration of such Interest Period); provided that, if any or
                  all of the Lenders object to the requested duration of such

                  last day of such Interest Period shall be extended to occur on
                  the next succeeding Business Day, provided, however, that, if
                  such extension would cause the last day of such Interest
                  Period to occur in the next following calendar month, the last
                  day of such Interest Period shall occur on the next preceding
                  Business Day; and

                           (v) whenever the first day of any Interest Period

conditions set forth in Article III, including, without limitation, any loss
(excluding loss of anticipated profits), cost or expense incurred by reason of

Credit Borrowing, the Agent may assume that such Lender has made such portion

amount together with interest thereon, for each day from the date such amount is
made available to the Borrower until the date such amount is repaid to the
Agent, at (i) in the case of the Borrower, the interest rate applicable at the
time to Revolving Credit Advances comprising such Revolving Credit Borrowing and
(ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall
repay to the Agent such corresponding amount, such amount so repaid shall
constitute such Lender's Revolving Credit Advance as part of such Revolving
Credit Borrowing for purposes of this Agreement.

                  (e) The failure of any Lender to make the Revolving Credit
Advance to be made by it as part of any Revolving Credit Borrowing shall not
relieve any other Lender of its obligation, if any, hereunder to make its
Revolving Credit Advance on the date of such Revolving Credit Borrowing, but no
Lender shall be responsible for the failure of any other Lender to make the
Revolving Credit Advance to be made by such other Lender on the date of any
Revolving Credit Borrowing.

                  SECTION 2.03. The Competitive Bid Advances. (a) Each Lender
severally agrees that the Borrower may make Competitive Bid Borrowings under
this Section 2.03 from time to time on any Business Day during the period from
the date hereof until the date occurring 30 days prior to the Termination Date
in the manner set forth below; provided that, following the making of each
Competitive Bid Borrowing, the aggregate Usage shall not exceed the Revolving
Credit Facility.

                  (i) The Borrower may request a Competitive Bid Borrowing under
         this Section 2.03 by delivering to the Agent, by telecopier or telex, a
         notice of a Competitive Bid Borrowing (a "Notice of Competitive Bid
         Borrowing"), in substantially the form of Exhibit B-2 hereto,
         specifying therein the requested (v) date of such proposed Competitive
         Bid Borrowing, (w) aggregate amount of such proposed Competitive Bid
         Borrowing, (x) in the case of a Competitive Bid Borrowing consisting of
         LIBO Rate Advances, Interest Period, or in the case of a Competitive
         Bid Borrowing consisting of Fixed Rate Advances, maturity date for
         repayment of each Fixed Rate Advance to be made as part of such
         Competitive Bid Borrowing (which maturity date may not be earlier than
         the date occurring 7 days after the date of such Competitive Bid
         Borrowing or later than the earlier of (I) 180 days after the date of
         such Competitive Bid Borrowing and (II) the Termination Date), (y)
         interest payment date or dates relating thereto, and (z) other terms
         (if any) to be applicable to such Competitive Bid Borrowing, not later
         than 10:00 A.M. (New York City time) (A) at least one Business Day
         prior to the date of the proposed Competitive Bid Borrowing, if the
         Borrower shall specify in the Notice of Competitive Bid Borrowing that
         the rates of interest to be offered by the Lenders shall be fixed rates
         per annum (the Advances comprising any such Competitive Bid Borrowing
         being referred to herein as "Fixed Rate Advances") and (B) at least
         four Business Days prior to the date of the proposed Competitive Bid
         Borrowing, if the Borrower shall instead specify in the Notice of
         Competitive Bid Borrowing that the Advances comprising such Competitive
         Bid Borrowing shall be LIBO Rate Advances. Each Notice of Competitive
         Bid Borrowing shall be irrevocable and binding on the Borrower. The
         Agent shall in turn promptly notify each Lender of each request for a
         Competitive Bid Borrowing received by it from the Borrower by sending
         such Lender a copy of the related Notice of Competitive Bid Borrowing.

                  (ii) Each Lender may, if, in its sole discretion, it elects to
         do so, irrevocably offer to make one or more Competitive Bid Advances
         to the Borrower as part of such proposed Competitive Bid Borrowing at a
         rate or rates of interest specified by such Lender in its sole
         discretion, by notifying the Agent (which shall give prompt notice
         thereof to the Borrower), (A) before 9:30 A.M. (New York City time) on
         the date of such proposed Competitive Bid Borrowing, in the case of a
         Competitive Bid Borrowing consisting of Fixed Rate Advances and (B)
         before 10:00 A.M. (New York City time) three

                                       12
<PAGE>   18
         Business Days before the date of such proposed Competitive Bid
         Borrowing, in the case of a Competitive Bid Borrowing consisting of
         LIBO Rate Advances of the minimum amount and maximum amount of each
         Competitive Bid Advance which such Lender would be willing to make as
         part of such proposed Competitive Bid Borrowing (which amounts may,
         subject to the proviso to the first sentence of this Section 2.03(a),
         exceed such Lender's Revolving Credit Commitment, if any), the rate or
         rates of interest therefor and such Lender's Applicable Lending Office
         with respect to such Competitive Bid Advance; provided that if the
         Agent in its capacity as a Lender shall, in its sole discretion, elect
         to make any such offer, it shall notify the Borrower of such offer at
         least 30 minutes before the time and on the date on which notice of
         such election is to be given to the Agent, by the other Lenders. If any
         Lender shall elect not to make such an offer, such Lender shall so
         notify the Agent before 10:00 A.M. (New York City time) on the date on
         which notice of such election is to be given to the Agent by the other
         Lenders, and such Lender shall not be obligated to, and shall not, make
         any Competitive Bid Advance as part of such Competitive Bid Borrowing;
         provided that the failure by any Lender to give such notice shall not
         cause such Lender to be obligated to make any Competitive Bid Advance
         as part of such proposed Competitive Bid Borrowing.

                  (iii) The Borrower shall, in turn, (A) before 10:30 A.M. (New
         York City time) on the date of such proposed Competitive Bid Borrowing,
         in the case of a Competitive Bid Borrowing consisting of Fixed Rate
         Advances and (B) before 11:00 A.M. (New York City time) three Business
         Days before the date of such proposed Competitive Bid Borrowing, in the
         case of a Competitive Bid Borrowing consisting of LIBO Rate Advances,
         either:

                           (x) cancel such Competitive Bid Borrowing by giving
                  the Agent notice to that effect, or

                           (y) accept one or more of the offers made by any
                  Lender or Lenders pursuant to paragraph (ii) above, in its
                  sole discretion, by giving notice to the Agent of the amount
                  of each Competitive Bid Advance (which amount shall be equal
                  to or greater than the minimum amount, and equal to or less
                  than the maximum amount, notified to the Borrower by the Agent
                  on behalf of such Lender for such Competitive Bid Advance
                  pursuant to paragraph (ii) above) to be made by each Lender as
                  part of such Competitive Bid Borrowing, and reject any
                  remaining offers made by Lenders pursuant to paragraph (ii)
                  above by giving the Agent notice to that effect. The Borrower
                  shall accept the offers made by any Lender or Lenders to make
                  Competitive Bid Advances in order of the lowest to the highest
                  rates of interest offered by such Lenders. If two or more
                  Lenders have offered the same interest rate, the amount to be
                  borrowed at such interest rate will be allocated among such
                  Lenders in proportion to the amount that each such Lender
                  offered at such interest rate.

                  (iv) If the Borrower notifies the Agent that such Competitive
         Bid Borrowing is cancelled pursuant to paragraph (iii)(x) above, the
         Agent shall give prompt notice thereof to the Lenders and such
         Competitive Bid Borrowing shall not be made.

                  (v) If the Borrower accepts one or more of the offers made by
         any Lender or Lenders pursuant to paragraph (iii)(y) above, the Agent
         shall in turn promptly notify (A) each Lender that has made an offer as
         described in paragraph (ii) above, of the date and aggregate amount of
         such Competitive Bid Borrowing and whether or not any offer or offers
         made by such Lender pursuant to paragraph (ii) above have been accepted
         by the Borrower, (B) each Lender that is to make a Competitive Bid
         Advance as part of such Competitive Bid Borrowing, of the amount of
         each Competitive Bid Advance to be made by such Lender as part of such
         Competitive Bid Borrowing, and (C) each Lender that is to make a
         Competitive Bid Advance as part of such Competitive Bid Borrowing, upon
         receipt, that the Agent has received forms of documents appearing to
         fulfill the applicable conditions set forth in Article III. Each Lender
         that is to make a Competitive Bid Advance as part of such Competitive
         Bid Borrowing shall, before 12:00 noon (New York City time) on the date
         of such Competitive Bid Borrowing specified in the notice received from
         the Agent pursuant to clause (A) of the preceding sentence or any later
         time when such Lender shall have received notice from the Agent
         pursuant to clause (C) of the preceding sentence, make available for
         the

                                       13
<PAGE>   19
         account of its Applicable Lending Office to the Agent at the Agent's
         Account, in same day funds, such Lender's portion of such Competitive
         Bid Borrowing. Upon fulfillment of the applicable conditions set forth
         in Article III and after receipt by the Agent of such funds, the Agent
         will make such funds available to the Borrower at the Agent's address
         referred to in Section 8.02. Promptly after each Competitive Bid
         Borrowing the Agent will notify each Lender of the amount of the
         Competitive Bid Borrowing and the dates upon which such Competitive Bid
         Borrowing commenced and will terminate.

                  (vi) If the Borrower notifies the Agent that it accepts one or
         more of the offers made by any Lender or Lenders pursuant to paragraph
         (iii)(y) above, such notice of acceptance shall be irrevocable and
         binding on the Borrower. The Borrower shall indemnify each Lender
         against any loss, cost or expense incurred by such Lender as a result
         of any failure to fulfill on or before the date specified in the
         related Notice of Competitive Bid Borrowing for such Competitive Bid
         Borrowing the applicable conditions set forth in Article III,
         including, without limitation, any loss (excluding loss of anticipated
         profits), cost or expense incurred by reason of the liquidation or
         reemployment of deposits or other funds acquired by such Lender to fund
         the Competitive Bid Advance to be made by such Lender as part of such
         Competitive Bid Borrowing when such Competitive Bid Advance, as a
         result of such failure, is not made on such date.

                  (b) Each Competitive Bid Borrowing shall be in an aggregate
amount of $10,000,000 or an integral multiple of $1,000,000 in excess thereof
and, following the making of each Competitive Bid Borrowing, the Borrower shall
be in compliance with the limitation set forth in the proviso to the first
sentence of subsection (a) above.

                  (c) Within the limits and on the conditions set forth in this
Section 2.03, the Borrower may from time to time borrow under this Section 2.03,
repay or prepay pursuant to subsection (d) below, and reborrow under this
Section 2.03, provided that a Competitive Bid Borrowing shall not be made within
three Business Days of the date of any other Competitive Bid Borrowing.

                  (d) The Borrower shall repay to the Agent for the account of
each Lender that has made a Competitive Bid Advance, on the maturity date of
each Competitive Bid Advance (such maturity date being that specified by the
Borrower for repayment of such Competitive Bid Advance in the related Notice of
Competitive Bid Borrowing delivered pursuant to subsection (a)(i) above and
provided in the Competitive Bid Note evidencing such Competitive Bid Advance),
the then unpaid principal amount of such Competitive Bid Advance. The Borrower
shall have no right to prepay any principal amount of any Competitive Bid
Advance unless, and then only on the terms, specified by the Borrower for such
Competitive Bid Advance in the related Notice of Competitive Bid Borrowing
delivered pursuant to subsection (a)(i) above and set forth in the Competitive
Bid Note evidencing such Competitive Bid Advance.

                  (e) The Borrower shall pay interest on the unpaid principal
amount of each Competitive Bid Advance from the date of such Competitive Bid
Advance to the date the principal amount of such Competitive Bid Advance is
repaid in full, at the rate of interest for such Competitive Bid Advance
specified by the Lender making such Competitive Bid Advance in its notice with
respect thereto delivered pursuant to subsection (a)(ii) above, payable on the
interest payment date or dates specified by the Borrower for such Competitive
Bid Advance in the related Notice of Competitive Bid Borrowing delivered
pursuant to subsection (a)(i) above, as provided in the Competitive Bid Note
evidencing such Competitive Bid Advance. Upon the occurrence and during the
continuance of an Event of Default under Section 6.01(a), the Borrower shall pay
interest on the amount of unpaid principal of and interest on each Competitive
Bid Advance owing to a Lender, payable in arrears on the date or dates interest
is payable thereon, at a rate per annum equal at all times to 2% per annum above
the rate per annum required to be paid on such Competitive Bid Advance under the
terms of the Competitive Bid Note evidencing such Competitive Bid Advance unless
otherwise agreed in such Competitive Bid Note.

                  (f) The indebtedness of the Borrower resulting from each
Competitive Bid Advance made to the Borrower as part of a Competitive Bid
Borrowing shall be evidenced by a separate Competitive Bid Note of the Borrower
payable to the order of the Lender making such Competitive Bid Advance.

                  SECTION 2.04. Fees. (a) Facility Fee. The Borrower agrees to
pay to the Agent for the account of each Lender a facility fee on the aggregate
amount of such Lender's Revolving Credit Commitment from the Effective Date in
the case of each Initial Lender and from the effective date specified in the
Assignment and Acceptance pursuant to which it became a Lender in the case of
each other Lender until the Termination Date at a rate per annum equal to the
Applicable Percentage in effect from time to time, payable in arrears quarterly
on the last day of each March, June, September and December, commencing June 30,
2001, and on the Termination Date.

                  (b) Agent's Fees. The Borrower shall pay to the Agent for its
own account such fees as may from time to time be agreed between the Borrower
and the Agent.

                  SECTION 2.05. Optional Termination or Reduction of the
Commitments. The Borrower shall have the right, upon at least three Business
Days' notice to the Agent, to terminate in whole or permanently reduce ratably
in part the unused portions of the respective Unused Revolving Credit
Commitments of the Lenders, provided that each partial reduction shall be in the
aggregate amount of $10,000,000 or an integral multiple of $1,000,000 in excess
thereof.

                  SECTION 2.06. Repayment of Revolving Credit Advances. The
Borrower shall repay to the Agent for the ratable account of the Lenders on the
Termination Date the aggregate principal amount of the Revolving Credit Advances
then outstanding.

                  SECTION 2.07. Interest on Revolving Credit Advances. (a)
Scheduled Interest. The Borrower shall pay interest on the unpaid principal
amount of each Revolving Credit Advance owing to each Lender from the date of
such Revolving Credit Advance until such principal amount shall be paid in full,
at the following rates per annum:

                  (i) Base Rate Advances. During such periods as such Advance is
         a Base Rate Advance, a rate per annum equal at all times to the sum of
         (x) the Base Rate in effect from time to time plus (y) the Applicable
         Margin in effect from time to time plus (z) the Applicable Utilization
         Fee in effect from time to time, payable in arrears quarterly on the
         last day of each March, June, September and December during such
         periods and on the date such Base Rate Advance shall be Converted or
         paid in full.

                  (ii) Eurodollar Rate Advances. During such periods as such
         Advance is a Eurodollar Rate Advance, a rate per annum equal at all
         times during each Interest Period for such Revolving Credit Advance to
         the sum of (x) the Eurodollar Rate for such Interest Period for such
         Revolving Credit Advance plus (y) the Applicable Margin in effect from
         time to time plus (z) the Applicable Utilization Fee in effect from
         time to time, payable in arrears on the last day of such Interest
         Period and, if such Interest Period has a duration of more than three
         months, on each day that occurs during such Interest Period every three
         months from the first day of such Interest Period and on the date such
         Eurodollar Rate Advance shall be Converted or paid in full.

                  (b) Default Interest. Upon the occurrence and during the
continuance of an Event of Default under Section 6.01(a), the Agent may, and
upon the request of the Required Lenders shall, require the Borrower to pay
interest ("Default Interest") on (i) the unpaid principal amount of each
Revolving Credit Advance owing to each Lender, payable in arrears on the dates
referred to in clause (a)(i) or (a)(ii) above, at a rate per annum equal at all
times to 2% per annum above the rate per annum required to be paid on such
Revolving Credit Advance pursuant to clause (a)(i) or (a)(ii) above and (ii) to
the fullest extent permitted by law, the amount of any interest, fee or other
amount payable hereunder that is not paid when due, from the date such amount
shall be due until such amount shall be paid in full, payable in arrears on the
date such amount shall be paid in full and on demand, at a rate per annum equal
at all times to 2% per annum above the rate per annum required to be paid on
Base Rate Advances pursuant to clause (a)(i) above, provided, however, that
following acceleration of the Advances pursuant to Section 6.01, Default
Interest shall accrue and be payable hereunder whether or not previously
required by the Agent.

                  SECTION 2.08. Interest Rate Determination. (a) Each Reference
Bank agrees to furnish to the Agent timely information for the purpose of
determining each Eurodollar Rate and each LIBO Rate. If any one or more of the
Reference Banks shall not furnish such timely information to the Agent for the
purpose of determining

                                       15
<PAGE>   21
any such interest rate, the Agent shall determine such interest rate on the
basis of timely information furnished by the remaining Reference Banks. The
Agent shall give prompt notice to the Borrower and the Lenders of the applicable
interest rate determined by the Agent for purposes of Section 2.07(a)(i) or
(ii), and the rate, if any, furnished by each Reference Bank for the purpose of
determining the interest rate under Section 2.07(a)(ii).

                  (b) If, with respect to any Eurodollar Rate Advances, the
Required Lenders notify the Agent that the Eurodollar Rate for any Interest
Period for such Advances will not adequately reflect the cost to such Required
Lenders of making, funding or maintaining their respective Eurodollar Rate
Advances for such Interest Period, the Agent shall forthwith so notify the
Borrower and the Lenders, whereupon (i) each Eurodollar Rate Advance will
automatically, on the last day of the then existing Interest Period therefor,
Convert into a Base Rate Advance, and (ii) the obligation of the Lenders to
make, or to Convert Revolving Credit Advances into, Eurodollar Rate Advances
shall be suspended until the Agent shall notify the Borrower and the Lenders
that the circumstances causing such suspension no longer exist.

                  (c) If the Borrower shall fail to select the duration of any
Interest Period for any Eurodollar Rate Advances in accordance with the
provisions contained in the definition of "Interest Period" in Section 1.01, the
Agent will forthwith so notify the Borrower and the Lenders and such Advances
will automatically, on the last day of the then existing Interest Period
therefor, Convert into Base Rate Advances.

                  (d) On the date on which the aggregate unpaid principal amount
of Eurodollar Rate Advances comprising any Borrowing shall be reduced, by
payment or prepayment or otherwise, to less than $10,000,000, such Advances
shall automatically Convert into Base Rate Advances.

                  (e) Upon the occurrence and during the continuance of any
Event of Default under Section 6.01(a), (i) each Eurodollar Rate Advance will
automatically, on the last day of the then existing Interest Period therefor,
Convert into a Base Rate Advance and (ii) the obligation of the Lenders to make,
or to Convert Advances into, Eurodollar Rate Advances shall be suspended.

                  (f) If Telerate Markets Page 3750 is unavailable and fewer
than two Reference Banks furnish timely information to the Agent for determining
the Eurodollar Rate or LIBO Rate for any Eurodollar Rate Advances or LIBO Rate
Advances, as the case may be,

                  (i) the Agent shall forthwith notify the Borrower and the
         Lenders that the interest rate cannot be determined for such Eurodollar
         Rate Advances or LIBO Rate Advances, as the case may be,

                  (ii) with respect to Eurodollar Rate Advances, each such
         Advance will automatically, on the last day of the then existing
         Interest Period therefor, Convert into a Base Rate Advance (or if such
         Advance is then a Base Rate Advance, will continue as a Base Rate
         Advance), and

                  (iii) the obligation of the Lenders to make Eurodollar Rate
         Advances or LIBO Rate Advances or to Convert Revolving Credit Advances
         into Eurodollar Rate Advances shall be suspended until the Agent shall
         notify the Borrower and the Lenders that the circumstances causing such
         suspension no longer exist.

                  SECTION 2.09. Optional Conversion of Revolving Credit
Advances. The Borrower may on any Business Day, upon notice given to the Agent
not later than 11:00 A.M. (New York City time) on the third Business Day prior
to the date of the proposed Conversion and subject to the provisions of Sections
2.08 and 2.12, Convert all Revolving Credit Advances of one Type comprising the
same Borrowing into Revolving Credit Advances of the other Type; provided,
however, that any Conversion of Eurodollar Rate Advances into Base Rate Advances
shall be made only on the last day of an Interest Period for such Eurodollar
Rate Advances, any Conversion of Base Rate Advances into Eurodollar Rate
Advances shall be in an amount not less than the minimum amount specified in
Section 2.02(b) and no Conversion of any Revolving Credit Advances shall result
in more separate Revolving Credit Borrowings than permitted under Section
2.02(b). Each such notice of a Conversion shall, within the restrictions
specified above, specify (i) the date of such Conversion, (ii) the Revolving
Credit Advances to be Converted, and

                                       16
<PAGE>   22
(iii) if such Conversion is into Eurodollar Rate Advances, the duration of the
initial Interest Period for each such Advance. Each notice of Conversion shall
be irrevocable and binding on the Borrower.

                  SECTION 2.10. Prepayments of Revolving Credit Advances. (a)
Optional. The Borrower may, upon notice at least three Business Days' prior to
the date of such prepayment, in the case of Eurodollar Rate Advances, and not
later than 11:00 A.M. (New York City time) on the date of such prepayment, in
the case of Base Rate Advances, to the Agent stating the proposed date and
aggregate principal amount of the prepayment, and if such notice is given the
Borrower shall, prepay the outstanding principal amount of the Revolving Credit
Advances comprising part of the same Revolving Credit Borrowing in whole or
ratably in part, together with accrued interest to the date of such prepayment
on the principal amount prepaid; provided, however, that (x) each partial
prepayment shall be in an aggregate principal amount of $10,000,000 or an
integral multiple of $1,000,000 in excess thereof and (y) in the event of any
such prepayment of a Eurodollar Rate Advance, the Borrower shall be obligated to
reimburse the Lenders in respect thereof pursuant to Section 8.04(c).

                  (b) Mandatory. The Borrower shall, on each Business Day,
prepay an aggregate principal amount of the Revolving Credit Advances comprising
part of the same Revolving Credit Borrowing equal to the amount by which the
aggregate principal amount of the Advances then outstanding exceeds the
Revolving Credit Facility on such Business Day.

                  SECTION 2.11. Increased Costs. (a) If, due to either (i) the
introduction of or any change in or in the interpretation of any law or
regulation or (ii) the compliance with any guideline or request from any central
bank or other governmental authority (whether or not having the force of law),
there shall be any increase in the cost to any Lender of agreeing to make or
making, funding or maintaining Eurodollar Rate Advances or LIBO Rate Advances
(excluding for purposes of this Section 2.11 any such increased costs resulting
from (i) Taxes or Other Taxes (as to which Section 2.14 shall govern) and (ii)
changes in the basis of taxation of overall net income or overall gross income
by the United States or by the foreign jurisdiction or state under the laws of
which such Lender is organized or has its Applicable Lending Office or any
political subdivision thereof), then the Borrower shall from time to time, upon
demand by such Lender (with a copy of such demand to the Agent), pay to the
Agent for the account of such Lender additional amounts sufficient to compensate
such Lender for such increased cost; provided, however, that before making any
such demand, each Lender agrees to use reasonable efforts (consistent with its
internal policy and legal and regulatory restrictions) to designate a different
Applicable Lending Office if the making of such a designation would avoid the
need for, or reduce the amount of, such increased cost and would not, in the
reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.
A certificate as to the amount of such increased cost, submitted to the Borrower
and the Agent by such Lender, shall be conclusive and binding for all purposes,
absent manifest error.

                  (b) If any Lender determines that compliance with any law or
regulation or any guideline or request from any central bank or other
governmental authority (whether or not having the force of law) affects or would
affect the amount of capital required or expected to be maintained by such
Lender or any corporation controlling such Lender and that the amount of such
capital is increased by or based upon the existence of such Lender's commitment
to lend hereunder and other commitments of such type, then, upon demand by such
Lender (with a copy of such demand to the Agent), the Borrower shall pay to the
Agent for the account of such Lender, from time to time as specified by such
Lender, additional amounts sufficient to compensate such Lender or such
corporation in the light of such circumstances, to the extent that such Lender
reasonably determines such increase in capital to be allocable to the existence
of such Lender's commitment to lend hereunder. A certificate as to such amounts
submitted to the Borrower and the Agent by such Lender shall be conclusive and
binding for all purposes, absent manifest error.

                  (c) Failure or delay on the part of any Lender to demand
compensation pursuant to this Section 2.11 shall not constitute a waiver of such
Lender's right to demand such compensation; provided that the Borrower shall not
be required to compensate such Lender pursuant to this Section for any increased
costs or reductions incurred more than 180 days prior to the date that such
Lender notifies the Borrower of the event giving rise to such increased costs or
reductions and of such Lender's intention to claim compensation therefor;
provided, further that, if the event giving rise to such increased costs or
reductions is retroactive, then the 180 day period referred to above shall be
extended to include the period of retroactive effect thereof.

                  SECTION 2.12. Illegality. Notwithstanding any other provision
of this Agreement, if any Lender shall notify the Agent that the introduction of
or any change in or in the interpretation of any law or regulation makes it
unlawful, or any central bank or other governmental authority asserts that it is
unlawful, for any Lender or its Eurodollar Lending Office to perform its
obligations hereunder to make Eurodollar Rate Advances or LIBO Rate Advances or
to fund or maintain Eurodollar Rate Advances or LIBO Rate Advances hereunder,
(a) each Eurodollar Rate Advance or LIBO Rate Advance, as the case may be, will
automatically, at the end of the applicable Interest Period then in effect if
permitted and otherwise upon such demand, Convert into a Base Rate Advance or an
Advance that bears interest at the rate set forth in Section 2.07(a)(i), as the
case may be, and (b) the obligation of the Lenders to make Eurodollar Rate
Advances or LIBO Rate Advances or to Convert Revolving Credit Advances into
Eurodollar Rate Advances shall be suspended until the Agent shall notify the
Borrower and the Lenders that the circumstances causing such suspension no
longer exist; provided, however, that before making any such demand, each Lender
agrees to use reasonable efforts (consistent with its internal policy and legal
and regulatory restrictions) to designate a different Eurocurrency Lending
Office if the making of such a designation would allow such Lender or its
Eurocurrency Lending Office to continue to perform its obligations to make
Eurocurrency Rate Advances or to continue to fund or maintain Eurocurrency Rate
Advances and would not, in the judgment of such Lender, be otherwise
disadvantageous to such Lender.

                  SECTION 2.13. Payments and Computations. (a) The Borrower
shall make each payment hereunder, irrespective of any right of counterclaim or
set-off, not later than 11:00 A.M. (New York City time) on the day when due in
U.S. dollars to the Agent at the Agent's Account in same day funds. The Agent
will promptly thereafter cause to be distributed like funds relating to the
payment of principal or interest or facility fees ratably (other than amounts
payable pursuant to Section 2.03, 2.11, 2.14 or 8.04(c)) to the Lenders for the
account of their respective Applicable Lending Offices, and like funds relating
to the payment of any other amount payable to any Lender to such Lender for the
account of its Applicable Lending Office, in each case to be applied in
accordance with the terms of this Agreement. Upon its acceptance of an
Assignment and Acceptance and recording of the information contained therein in
the Register pursuant to Section 8.07(c), from and after the effective date
specified in such Assignment and Acceptance, the Agent shall make all payments
hereunder and under the Notes in respect of the interest assigned thereby to the
Lender assignee thereunder, and the parties to such Assignment and Acceptance
shall make all appropriate adjustments in such payments for periods prior to
such effective date directly between themselves.

                  (b) All computations of interest based on the Base Rate shall
be made by the Agent on the basis of a year of 365 or 366 days, as the case may
be, and all computations of interest based on the Eurodollar Rate, the LIBO Rate
or the Federal Funds Rate or in respect of Fixed Rate Advances and of facility
fees shall be made by the Agent on the basis of a year of 360 days, in each case
for the actual number of days (including the first day but excluding the last
day) occurring in the period for which such interest or facility fees are
payable. Each determination by the Agent of an interest rate hereunder shall be
conclusive and binding for all purposes, absent manifest error.

                  (c) Whenever any payment hereunder or under the Notes shall be
stated to be due on a day other than a Business Day, such payment shall be made
on the next succeeding Business Day, and such extension of time shall in such
case be included in the computation of payment of interest or facility fee, as
the case may be; provided, however, that, if such extension would cause payment
of interest on or principal of Eurodollar Rate Advances or LIBO Rate Advances to
be made in the next following calendar month, such payment shall be made on the
next preceding Business Day.

                  (d) Unless the Agent shall have received notice from the
Borrower prior to the date on which any payment is due to the Lenders hereunder
that the Borrower will not make such payment in full, the Agent may assume that
the Borrower has made such payment in full to the Agent on such date and the
Agent may, in reliance upon such assumption, cause to be distributed to each
Lender on such due date an amount equal to the amount then due such Lender. If
and to the extent the Borrower shall not have so made such payment in full to
the Agent, each Lender shall repay to the Agent forthwith on demand such amount
distributed to such Lender together with interest thereon, for each day from the
date such amount is distributed to such Lender until the date such Lender repays
such amount to the Agent, at the Federal Funds Rate.

                                       18
<PAGE>   24
                  SECTION 2.14. Taxes. (a) Any and all payments by the Borrower
to or for the account of any Lender or the Agent hereunder or under the Notes or
any other documents to be delivered hereunder shall be made, in accordance with
Section 2.13 or the applicable provisions of such other documents, free and
clear of and without deduction for any and all present or future taxes, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect
thereto, excluding, in the case of each Lender and the Agent, taxes imposed on
its overall net income, and franchise taxes imposed on it in lieu of net income
taxes, by the jurisdiction under the laws of which such Lender or the Agent (as
the case may be) is organized or any political subdivision thereof and, in the
case of each Lender, taxes imposed on its overall net income, and franchise
taxes imposed on it in lieu of net income taxes, by the jurisdiction of such
Lender's Applicable Lending Office or any political subdivision thereof (all
such non-excluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities in respect of payments hereunder or under the Notes being
hereinafter referred to as "Taxes"). If the Borrower shall be required by law to
deduct any Taxes from or in respect of any sum payable hereunder or under any
Note or any other documents to be delivered hereunder to any Lender or the
Agent, (i) the sum payable shall be increased as may be necessary so that after
making all required deductions (including deductions applicable to additional
sums payable under this Section 2.14) such Lender or the Agent (as the case may
be) receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions and (iii) the
Borrower shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law.

                  (b) In addition, the Borrower shall pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies that arise from any payment made hereunder or under the Notes or
any other documents to be delivered hereunder or from the execution, delivery or
registration of, performing under, or otherwise with respect to, this Agreement
or the Notes or any other documents to be delivered hereunder (hereinafter
referred to as "Other Taxes").

                  (c) The Borrower shall indemnify each Lender and the Agent for
and hold it harmless against the full amount of Taxes or Other Taxes (including,
without limitation, taxes of any kind imposed or asserted by any jurisdiction on
amounts payable under this Section 2.14) imposed on or paid by such Lender or
the Agent (as the case may be) and any liability (including penalties, interest
and expenses) arising therefrom or with respect thereto. This indemnification
shall be made within 30 days from the date such Lender or the Agent (as the case
may be) makes written demand therefor.

                  (d) Within 30 days after the date of any payment of Taxes, the
Borrower shall furnish to the Agent, at its address referred to in Section 8.02,
the original or a certified copy of a receipt evidencing such payment to the
extent such a receipt is issued therefor, or other written proof of payment
thereof that is reasonably satisfactory to the Agent. In the case of any payment
hereunder or under the Notes or any other documents to be delivered hereunder by
or on behalf of the Borrower through an account or branch outside the United
States or by or on behalf of the Borrower by a payor that is not a United States
person, if the Borrower determines that no Taxes are payable in respect thereof,
the Borrower shall furnish, or shall cause such payor to furnish, to the Agent,
at such address, an opinion of counsel acceptable to the Agent stating that such
payment is exempt from Taxes. For purposes of this subsection (d) and subsection
(e), the terms "United States" and "United States person" shall have the
meanings specified in Section 7701 of the Internal Revenue Code.

                  (e) Each Lender organized under the laws of a jurisdiction
outside the United States, on or prior to the date of its execution and delivery
of this Agreement in the case of each Initial Lender and on the date of the
Assumption Agreement or the Assignment and Acceptance pursuant to which it
becomes a Lender in the case of each other Lender, and from time to time
thereafter as reasonably requested in writing by the Borrower (but only so long
as such Lender remains lawfully able to do so), shall provide each of the Agent
and the Borrower with two original Internal Revenue Service forms W-8BEN or
W-8ECI, as appropriate, or any successor or other form prescribed by the
Internal Revenue Service, certifying that such Lender is exempt from or entitled
to a reduced rate of United States withholding tax on payments pursuant to this
Agreement or the Notes. If the form provided by a Lender at the time such Lender
first becomes a party to this Agreement indicates a United States interest
withholding tax rate in excess of zero, withholding tax at such rate shall be
considered excluded from Taxes unless and until such Lender provides the
appropriate forms certifying that a lesser rate applies, whereupon withholding
tax at such lesser rate only shall be considered excluded from Taxes for periods
governed by such form; provided, however, that, if at the date of the Assignment
and Acceptance pursuant to which a Lender assignee becomes a party

                                       19
<PAGE>   25
to this Agreement, the Lender assignor was entitled to payments under subsection
(a) in respect of United States withholding tax with respect to interest paid at
such date, then, to such extent, the term Taxes shall include (in addition to
withholding taxes that may be imposed in the future or other amounts otherwise
includable in Taxes) United States withholding tax, if any, applicable with
respect to the Lender assignee on such date. If any form or document referred to
in this subsection (e) requires the disclosure of information, other than
information necessary to compute the tax payable and information required on the
date hereof by Internal Revenue Service form W-8BEN or W-8ECI, that the Lender
reasonably considers to be confidential, the Lender shall give notice thereof to
the Borrower and shall not be obligated to include in such form or document such
confidential information.

                  (f) For any period with respect to which a Lender has failed
to provide the Borrower with the appropriate form, certificate or other document
described in Section 2.14(e) (other than if such failure is due to a change in
law, or in the interpretation or application thereof, occurring subsequent to
the date on which a form, certificate or other document originally was required
to be provided, or if such form, certificate or other document otherwise is not
required under subsection (e) above), such Lender shall not be entitled to
indemnification under Section 2.14(a) or (c) with respect to Taxes imposed by
the United States by reason of such failure; provided, however, that should a
Lender become subject to Taxes because of its failure to deliver a form,
certificate or other document required hereunder, the Borrower shall take such
steps as the Lender shall reasonably request to assist the Lender to recover
such Taxes.

                  SECTION 2.15. Sharing of Payments, Etc. If any Lender shall
obtain any payment (whether voluntary, involuntary, through the exercise of any
right of set-off, or otherwise) on account of the Revolving Credit Advances
owing to it (other than pursuant to Section 2.11, 2.14 or 8.04(c)) in excess of
its ratable share of payments on account of the Revolving Credit Advances
obtained by all the Lenders, such Lender shall forthwith purchase from the other
Lenders such participations in the Revolving Credit Advances owing to them as
shall be necessary to cause such purchasing Lender to share the excess payment
ratably with each of them; provided, however, that if all or any portion of such
excess payment is thereafter recovered from such purchasing Lender, such
purchase from each Lender shall be rescinded and such Lender shall repay to the
purchasing Lender the purchase price to the extent of such recovery together
with an amount equal to such Lender's ratable share (according to the proportion
of (i) the amount of such Lender's required repayment to (ii) the total amount
so recovered from the purchasing Lender) of any interest or other amount paid or
payable by the purchasing Lender in respect of the total amount so recovered.
The Borrower agrees that any Lender so purchasing a participation from another
Lender pursuant to this Section 2.15 may, to the fullest extent permitted by
law, exercise all its rights of payment (including the right of set-off) with
respect to such participation as fully as if such Lender were the direct
creditor of the Borrower in the amount of such participation.

                  SECTION 2.16. Evidence of Debt. (a) Each Lender shall maintain
in accordance with its usual practice an account or accounts evidencing the
indebtedness of the Borrower to such Lender resulting from each Revolving Credit
Advance owing to such Lender from time to time, including the amounts of
principal and interest payable and paid to such Lender from time to time
hereunder in respect of Revolving Credit Advances. The Borrower agrees that upon
notice by any Lender to the Borrower (with a copy of such notice to the Agent)
to the effect that a Revolving Credit Note is required or appropriate in order
for such Lender to evidence (whether for purposes of pledge, enforcement or
otherwise) the Revolving Credit Advances owing to, or to be made by, such
Lender, the Borrower shall promptly execute and deliver to such Lender a
Revolving Credit Note payable to the order of such Lender in a principal amount
up to the Revolving Credit Commitment of such Lender.

                  (b) The Register maintained by the Agent pursuant to Section
8.07(d) shall include a control account, and a subsidiary account for each
Lender, in which accounts (taken together) shall be recorded (i) the date and
amount of each Borrowing made hereunder, the Type of Advances comprising such
Borrowing and, if appropriate, the Interest Period applicable thereto, (ii) the
terms of each Assignment and Acceptance delivered to and accepted by it, (iii)
the amount of any principal or interest due and payable or to become due and
payable from the Borrower to each Lender hereunder and (iv) the amount of any
sum received by the Agent from the Borrower hereunder and each Lender's share
thereof.

                  (c) Entries made in good faith by the Agent in the Register
pursuant to subsection (b) above, and by each Lender in its account or accounts
pursuant to subsection (a) above, shall be prima facie evidence of the amount of
principal and interest due and payable or to become due and payable from the
Borrower to, in the case of

                                       20
<PAGE>   26
the Register, each Lender and, in the case of such account or accounts, such
Lender, under this Agreement, absent manifest error; provided, however, that the
failure of the Agent or such Lender to make an entry, or any finding that an
entry is incorrect, in the Register or such account or accounts shall not limit
or otherwise affect the obligations of the Borrower under this Agreement.

                  SECTION 2.17. Use of Proceeds. The proceeds of the Advances
shall be available (and the Borrower agrees that it shall use such proceeds)
solely for general corporate purposes of the Borrower and its Subsidiaries.

                                   ARTICLE III

         litigation or proceeding affecting the Borrower or any of its
         Subsidiaries pending or threatened before any court, governmental
         agency or arbitrator that (i) could be reasonably expected to have a
         Material Adverse Effect or (ii) purports to affect the legality,
         validity or enforceability of this Agreement or any Note or the
         consummation of the transactions contemplated hereby.

                  (c) Nothing shall have come to the attention of the Lenders
         during the course of their due diligence investigation to lead them to
         believe that the Information Memorandum was or has become misleading,
         incorrect or incomplete in any material respect; without limiting the
         generality of the foregoing, the Lenders shall have been given such
         access to the management, records, books of account, contracts and
         properties of the Borrower and its Subsidiaries as they shall have
         requested.

                  (d) All governmental and third party consents and approvals

         or regulation shall be applicable in the reasonable judgment of the
         Lenders that restrains, prevents or imposes materially adverse
         conditions upon the transactions contemplated hereby.

                  (e) The Borrower shall have notified the Agent, who will
         promptly notify each Lender, in writing as to the proposed Effective

         of counsel to the Agent).

                  (g) On the Effective Date, the following statements shall be
         true and the Agent shall have received for the account of each Lender a
         certificate signed by a duly authorized officer of the Borrower, dated
         the Effective Date, stating that:

                  Section 4.01 are correct on and as of the Effective Date,

                           (ii) No event has occurred and is continuing that

                  Agreement

                           By execution of this Agreement, each of the Lenders
                  that is a lender under either of the credit agreements
                  referred to in clause (iii) above hereby waives the
                  requirement set forth in Section 3.02 of each such credit
                  agreement of three business days' prior notice to the
                  termination of their commitments thereunder.

                  (h) The Agent shall have received on or before the Effective
         Date the following, each dated such day, in form and substance
         satisfactory to the Agent and (except for the Revolving Credit Notes)
         in sufficient copies for each Lender:

                           (i) The Revolving Credit Notes to the order of the
                  Lenders to the extent requested by any Lender pursuant to

                  the Agent.

                  SECTION 3.02. Conditions Precedent to Each Revolving Credit
Borrowing. The obligation of each Lender to make a Revolving Credit Advance on
the occasion of each Revolving Credit Borrowing shall be subject to the
conditions precedent that the Effective Date shall have occurred and on the date
of such Revolving Credit Borrowing (a) the following statements shall be true
(and each of the giving of the applicable Notice of Revolving Credit Borrowing
and the acceptance by the Borrower of the proceeds of such Revolving Credit
Borrowing shall constitute a representation and warranty by the Borrower that on
the date of such Borrowing such statements are true):

                  (i) the representations and warranties contained in Section
         4.01 (except the representations set forth in the last sentence of
         subsection (e) thereof and in subsection (f)(i) thereof) are correct on
         and as of such date, before and after giving effect to such Revolving
         Credit Borrowing and to the application of the proceeds therefrom, as
         though made on and as of such date, and

                  (ii) no event has occurred and is continuing, or would result
         from such Revolving Credit Borrowing or from the application of the
         proceeds therefrom, that constitutes a Default;

and (b) the Agent shall have received such other approvals, opinions or
documents as any Lender through the Agent may reasonably request.

                  SECTION 3.03. Conditions Precedent to Each Competitive Bid
Borrowing. The obligation of each Lender that is to make a Competitive Bid
Advance on the occasion of a Competitive Bid Borrowing to make

                                       22
<PAGE>   28
such Competitive Bid Advance as part of such Competitive Bid Borrowing is
subject to the conditions precedent that (i) the Agent shall have received the
written confirmatory Notice of Competitive Bid Borrowing with respect thereto,
(ii) on or before the date of such Competitive Bid Borrowing, but prior to such
Competitive Bid Borrowing, the Agent shall have received a Competitive Bid Note
payable to the order of such Lender for each of the one or more Competitive Bid
Advances to be made by such Lender as part of such Competitive Bid Borrowing, in

each of the giving of the applicable Notice of Competitive Bid Borrowing and the
acceptance by the Borrower of the proceeds of such Competitive Bid Borrowing

         of the proceeds therefrom, as though made on and as of such date,

                  (b) no event has occurred and is continuing, or would result
         from such Competitive Bid Borrowing or from the application of the
         proceeds therefrom, that constitutes a Default, and

                  (c) no event has occurred and no circumstance exists as a
         result of which the information concerning the Borrower that has been
         provided to the Agent and each Lender by the Borrower in connection
         herewith would include an untrue statement of a material fact or omit
         to state any material fact or any fact necessary to make the statements
         contained therein, in the light of the circumstances under which they
         were made, not misleading.

                  SECTION 3.04. Determinations Under Section 3.01. For purposes
of determining compliance with the conditions specified in Section 3.01, each
Lender shall be deemed to have consented to, approved or accepted or to be
satisfied with each document or other matter required thereunder to be consented
to or approved by or acceptable or satisfactory to the Lenders unless an officer
of the Agent responsible for the transactions contemplated by this Agreement
shall have received notice from such Lender prior to the date that the Borrower,
by notice to the Lenders, designates as the proposed Effective Date, specifying
its objection thereto. The Agent shall promptly notify the Lenders of the
occurrence of the Effective Date.

                  SECTION 5.01. Affirmative Covenants. So long as any Advance
shall remain unpaid or any Lender shall have any Commitment hereunder, the
Borrower will:

                  (a) Compliance with Laws, Etc. Comply, and cause each of its
         Subsidiaries to comply, in all material respects, with all applicable
         laws, rules, regulations and orders, such compliance to include,
         without limitation, compliance with ERISA and Environmental Laws.

                  (b) Payment of Taxes, Etc. Pay and discharge, and cause each
         of its Subsidiaries to pay and discharge, before the same shall become
         delinquent, (i) all taxes, assessments and governmental charges or
         levies imposed upon it or upon its property and (ii) all lawful claims
         that, if unpaid, might by law become a Lien upon its property;
         provided, however, that neither the Borrower nor any of its
         Subsidiaries shall be required to pay or discharge any such tax,
         assessment, charge or claim that (i) does not singly or in the
         aggregate exceed $25,000,000 or (ii) is being contested in good faith
         and by proper proceedings and as to which appropriate reserves are
         being maintained, unless and until any Lien resulting therefrom
         attaches to its property and becomes enforceable against its other
         creditors.

                                       24
<PAGE>   30
                  (c) Maintenance of Insurance. Maintain, and cause each of its
         Subsidiaries to maintain, insurance with responsible and reputable
         insurance companies or associations in such amounts and covering such
         risks as is usually carried by companies engaged in similar businesses
         and owning similar properties in the same general areas in which the
         Borrower or such Subsidiary operates.

                  (d) Preservation of Corporate Existence, Etc. Preserve and
         maintain, and cause each of its Subsidiaries to preserve and maintain,
         its corporate existence, rights (charter and statutory) and franchises;
         provided, however, that (i) the Borrower and its Subsidiaries may
         consummate any transaction permitted under Section 5.02(b), (ii) any
         Subsidiary the aggregate book value of the assets of which is less than
         $65,000,000 will not be subject to this Section 5.01(d) and (iii)
         neither the Borrower nor any of its Subsidiaries shall be required to
         preserve any right or franchise or, in the case of any immaterial
         Subsidiary, its existence, if the Borrower or such Subsidiary shall
         determine that the preservation thereof is no longer desirable in the
         conduct of the business of the Borrower or such Subsidiary, as the case
         may be, and that the loss thereof is not disadvantageous in any
         material respect to the Borrower, such Subsidiary or the Lenders.

                  (e) Visitation Rights. At any reasonable time and from time to
         time upon reasonable notice, permit the Agent or any of the Lenders or
         any agents or representatives thereof, to examine and make copies of
         and abstracts from the records and books of account of, and visit the
         properties of, the Borrower and any of its Subsidiaries, and to discuss
         the affairs, finances and accounts of the Borrower and any of its
         Subsidiaries with any of their officers or directors and with their
         independent certified public accountants.

                  (f) Keeping of Books. Keep, and cause each of its Subsidiaries
         to keep, proper books of record and account, in which full and correct
         entries shall be made of all financial transactions and the assets and
         business of the Borrower and each such Subsidiary in accordance with
         generally accepted accounting principles in effect from time to time.

                  (g) Maintenance of Properties, Etc. Maintain and preserve, and
         cause each of its Subsidiaries to maintain and preserve, all of its
         material properties that are used or useful in the conduct of its
         business in good working order and condition, ordinary wear and tear
         excepted.

                  (h) Transactions with Affiliates. Conduct, and cause each of
         its Subsidiaries to conduct, all transactions otherwise permitted under
         this Agreement with any of their Affiliates (other than the Borrower
         and its Subsidiaries) on terms that are fair and reasonable and no less
         favorable to the Borrower or such Subsidiary than it would obtain in a
         comparable arm's-length transaction with a Person not an Affiliate,
         except for transactions with joint ventures in which the Borrower owns,
         directly or indirectly, an interest of at least 20%, which could not,
         singly or in the aggregate, reasonably be expected to have a Material
         Adverse Effect.

         type as that engaged in by the Borrower and its Subsidiaries, provided,
         in each case, that no Default shall have occurred and be continuing at
         the time of such proposed transaction or would result therefrom and
         provided, further, that any Subsidiary of the Borrower the then
         aggregate book value of the assets of which is less than $65,000,000
         shall not be subject to this Section 5.02(b).

                  (c) Accounting Changes. Make or permit, or permit any of its
         Subsidiaries to make or permit, any change in accounting policies or

                  SECTION 5.03. Financial Covenants. So long as any Advance

         after the applicable grace period, if any, specified in the agreement
         or instrument relating to such Debt; or any other event shall occur or
         condition shall exist under any agreement or instrument relating to any

         shall be required to be made, in each case prior to the stated maturity
         thereof; or

                  (e) The Borrower or any of its Subsidiaries shall generally
         not pay its debts as such debts become due, or shall admit in writing
         its inability to pay its debts generally, or shall make a general
         assignment for the benefit of creditors; or any proceeding shall be

         seeking to adjudicate it a bankrupt or insolvent, or seeking
         liquidation, winding up, reorganization, arrangement, adjustment,

<PAGE>   34
         relief or the appointment of a receiver, trustee, custodian or other
         similar official for it or for any substantial part of its property
         and, in the case of any such proceeding instituted against it (but not
         instituted by it), either such proceeding shall remain undismissed or
         unstayed for a period of 30 days, or any of the actions sought in such
         proceeding (including, without limitation, the entry of an order for
         relief against, or the appointment of a receiver, trustee, custodian or
         other similar official for, it or for any substantial part of its
         property) shall occur; or the Borrower or any of its Subsidiaries shall
         take any corporate action to authorize any of the actions set forth
         above in this subsection (e); or

                  (f) Judgments or orders for the payment of money in excess of

         have been commenced by any creditor upon such judgment or order or (ii)
         there shall be any period of 10 consecutive days during which a stay of
         enforcement of such judgment or order, by reason of a pending appeal or

         Stock of the Borrower; or (ii) during any period of up to 24
         consecutive months, commencing before or after the date of this

         were directors of the Borrower shall cease for any reason to constitute
         a majority of the board of directors of the Borrower (except to the
         extent that individuals who at the beginning of such 24-month period
         were replaced by individuals (x) elected by a majority of the remaining
         members of the board of directors of the Borrower or (y) nominated for
         election by a majority of the remaining members of the board of
         directors of the Borrower and thereafter elected as directors by the
         shareholders of the Borrower) or

                  (i) The Borrower or any of its ERISA Affiliates shall incur,
         or, in the reasonable opinion of the Required Lenders, shall be
         reasonably likely to incur liability in excess of $25,000,000 in the

         of the Borrower or any of its ERISA Affiliates from a Multiemployer
         Plan; or (iii) the reorganization or termination of a Multiemployer
         Plan;

then, and in any such event, the Agent (i) shall at the request, or may with the
consent, of the Required Lenders, by notice to the Borrower, declare the
obligation of each Lender to make Advances to be terminated, whereupon the same
shall forthwith terminate, and (ii) shall at the request, or may with the
consent, of the Required Lenders, by notice to the Borrower, declare the
Advances, all interest thereon and all other amounts payable under this
Agreement to be forthwith due and payable, whereupon the Advances, all such
interest and all such amounts shall become and be forthwith due and payable,
without presentment, demand, protest or further notice of any kind, all of which
are hereby expressly waived by the Borrower; provided, however, that in the
event of an actual or deemed entry of an order for relief with respect to the
Borrower under the Federal Bankruptcy Code, (A) the obligation of each Lender to
make Advances shall automatically be terminated and (B) the Advances, all such
interest and all such amounts shall automatically become and be due and payable,
without presentment, demand, protest or any notice of any kind, all of which are
hereby expressly waived by the Borrower.

                                   ARTICLE VII

                                    THE AGENT

                  SECTION 7.01. Authorization and Action. Each Lender hereby
appoints and authorizes the Agent to take such action as agent on its behalf and
to exercise such powers and discretion under this Agreement as are delegated to
the Agent by the terms hereof, together with such powers and discretion as are
reasonably incidental thereto. As to any matters not expressly provided for by
this Agreement (including, without limitation, enforcement or collection of the
Notes), the Agent shall not be required to exercise any discretion or take any
action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the


                                       29
<PAGE>   35
instructions of the Required Lenders, and such instructions shall be binding
upon all Lenders and all holders of Notes; provided, however, that the Agent
shall not be required to take any action that exposes the Agent to personal
liability or that is contrary to this Agreement or applicable law. The Agent
agrees to give to each Lender prompt notice of each notice given to it by the
Borrower pursuant to the terms of this Agreement.

                  SECTION 7.02. Agent's Reliance, Etc. Neither the Agent nor any
of its directors, officers, agents or employees shall be liable for any action
taken or omitted to be taken by it or them under or in connection with this
Agreement, except for its or their own gross negligence or willful misconduct.
Without limitation of the generality of the foregoing, the Agent: (i) may treat
the Lender that made any Advance as the holder of the Debt resulting therefrom
until the Agent receives and accepts an Assignment and Acceptance entered into
by such Lender, as assignor, and an Eligible Assignee, as assignee, as provided
in Section 8.07; (ii) may consult with legal counsel (including counsel for the
Borrower), independent public accountants and other experts selected by it and
shall not be liable for any action taken or omitted to be taken in good faith by
it in accordance with the advice of such counsel, accountants or experts; (iii)
makes no warranty or representation to any Lender and shall not be responsible
to any Lender for any statements, warranties or representations (whether written
or oral) made in or in connection with this Agreement; (iv) shall not have any
duty to ascertain or to inquire as to the performance, observance or
satisfaction of any of the terms, covenants or conditions of this Agreement on
the part of the Borrower or the existence at any time of any Default or to
inspect the property (including the books and records) of the Borrower; (v)
shall not be responsible to any Lender for the due execution, legality,
validity, enforceability, genuineness, sufficiency or value of this Agreement or
any other instrument or document furnished pursuant hereto; and (vi) shall incur
no liability under or in respect of this Agreement by acting upon any notice,
consent, certificate or other instrument or writing (which may be by telecopier,
telegram or telex) believed by it to be genuine and signed or sent by the proper
party or parties.

                  SECTION 7.03. Citibank and Affiliates. With respect to its
Commitment, the Advances made by it and the Note issued to it, Citibank shall
have the same rights and powers under this Agreement as any other Lender and may
exercise the same as though it were not the Agent; and the term "Lender" or
"Lenders" shall, unless otherwise expressly indicated, include Citibank in its
individual capacity. Citibank and its Affiliates may accept deposits from, lend
money to, act as trustee under indentures of, accept investment banking
engagements from and generally engage in any kind of business with, the
Borrower, any of its Subsidiaries and any Person who may do business with or own
securities of the Borrower or any such Subsidiary, all as if Citibank were not
the Agent and without any duty to account therefor to the Lenders. The Agent
shall have no duty to disclose information obtained or received by it or any of
its Affiliates relating to the Borrower or its Subsidiaries to the extent such
information was obtained or received in any capacity other than as Agent.

                  SECTION 7.04. Lender Credit Decision. Each Lender acknowledges
that it has, independently and without reliance upon the Agent or any other
Lender and based on the financial statements referred to in Section 4.01 and
such other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the Agent or
any other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement.

                  SECTION 7.05. Indemnification. The Lenders agree to indemnify
the Agent (to the extent not reimbursed by the Borrower) from and against such
Lender's Ratable Share of any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever that may be imposed on, incurred by, or asserted
against the Agent in any way relating to or arising out of this Agreement or any
action taken or omitted by the Agent under this Agreement (collectively, the
"Indemnified Costs"), provided that no Lender shall be liable for any portion of
the Indemnified Costs resulting from the Agent's gross negligence or willful
misconduct. Without limitation of the foregoing, each Lender agrees to reimburse
the Agent promptly upon demand for its ratable share of any out-of-pocket
expenses (including reasonable counsel fees) incurred by the Agent in connection
with the preparation, execution, delivery, administration, modification,
amendment or enforcement (whether through negotiations, legal proceedings or
otherwise) of, or legal advice in respect of rights or responsibilities under,
this Agreement, to the extent that the Agent is not reimbursed for such expenses
by the Borrower. In the case of any investigation, litigation or proceeding
giving rise to any Indemnified


                                       30
<PAGE>   36
Costs, this Section 7.05 applies whether any such investigation, litigation or
proceeding is brought by the Agent, any Lender or a third party.

                  SECTION 7.06. Successor Agent. The Agent may resign at any
time by giving written notice thereof to the Lenders and the Borrower and may be
removed at any time with or without cause by the Required Lenders. Upon any such
resignation or removal, the Required Lenders shall have the right to appoint a
successor Agent. If no successor Agent shall have been so appointed by the
Required Lenders, and shall have accepted such appointment, within 30 days after
the retiring Agent's giving of notice of resignation or the Required Lenders'
removal of the retiring Agent, then the retiring Agent may, on behalf of the
Lenders, appoint a successor Agent, which shall be a commercial bank organized
under the laws of the United States of America or of any State thereof and
having a combined capital and surplus of at least $500,000,000. Upon the
acceptance of any appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the
rights, powers, discretion, privileges and duties of the retiring Agent, and the
retiring Agent shall be discharged from its duties and obligations under this
Agreement. After any retiring Agent's resignation or removal hereunder as Agent,
the provisions of this Article VII shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Agent under this Agreement.

                  SECTION 7.07. Other Agents. Each Lender hereby acknowledges
that neither the documentation agent nor any other Lender designated as any
"Agent" on the signature pages hereof has any liability hereunder other than in
its capacity as a Lender.

                                  ARTICLE VIII

                                  MISCELLANEOUS

                  SECTION 8.01. Amendments, Etc. No amendment or waiver of any
provision of this Agreement or the Revolving Credit Notes, nor consent to any
departure by the Borrower therefrom, shall in any event be effective unless the
same shall be in writing and signed by the Required Lenders, and then such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given; provided, however, that no amendment, waiver
or consent shall, unless in writing and signed by all the Lenders, do any of the
following: (a) waive any of the conditions specified in Section 3.01, (b)
increase the aggregate Revolving Credit Commitments of the Lenders, (c) reduce
the principal of, or interest on, the Revolving Credit Advances or any fees or
other amounts payable hereunder, (d) postpone any date fixed for any payment of
principal of, or interest on, the Revolving Credit Advances or any fees or other
amounts payable hereunder, (e) change the percentage of the Revolving Credit
Commitments or of the aggregate unpaid principal amount of the Revolving Credit
Advances, or the number of Lenders, that shall be required for the Lenders or
any of them to take any action hereunder or (f) amend this Section 8.01; and
provided further that no amendment, waiver or consent shall, unless in writing
and signed by the Agent in addition to the Lenders required above to take such
action, affect the rights or duties of the Agent under this Agreement or any
Note.

                  SECTION 8.02. Notices, Etc. All notices and other
communications provided for hereunder shall be in writing (including telecopier,
telegraphic or telex communication) and mailed, telecopied, telegraphed, telexed

answerback, respectively, except that notices and communications to the Agent

manually executed counterpart thereof.

<PAGE>   37
                  SECTION 8.03. No Waiver; Remedies. No failure on the part of
any Lender or the Agent to exercise, and no delay in exercising, any right
hereunder or under any Note shall operate as a waiver thereof; nor shall any
single or partial exercise of any such right preclude any other or further
exercise thereof or the exercise of any other right. The remedies herein
provided are cumulative and not exclusive of any remedies provided by law.

                  SECTION 8.04. Costs and Expenses. (a) The Borrower agrees to
pay on demand all costs and expenses of the Agent in connection with the
preparation, execution, delivery, administration, modification and amendment of
this Agreement, the Notes and the other documents to be delivered hereunder,
including, without limitation, (A) all due diligence, syndication (including
printing, distribution and bank meetings), transportation, computer,
duplication, appraisal, consultant, and audit expenses and (B) the reasonable
fees and expenses of counsel for the Agent with respect thereto and with respect
to advising the Agent as to its rights and responsibilities under this
Agreement. The Borrower further agrees to pay on demand all costs and expenses
of the Agent and the Lenders, if any (including, without limitation, reasonable
counsel fees and expenses), in connection with the enforcement (whether through
negotiations, legal proceedings or otherwise) of this Agreement, the Notes and
the other documents to be delivered hereunder, including, without limitation,
reasonable fees and expenses of counsel for the Agent and each Lender in
connection with the enforcement of rights under this Section 8.04(a).

                  (b) The Borrower agrees to indemnify and hold harmless the
Agent and each Lender and each of their Affiliates and their officers,
directors, employees, agents and advisors (each, an "Indemnified Party") from
and against any and all claims, damages, losses, liabilities and expenses
(including, without limitation, reasonable fees and expenses of counsel)
incurred by or asserted or awarded against any Indemnified Party, in each case
arising out of or in connection with or by reason of (including, without
limitation, in connection with any investigation, litigation or proceeding or
preparation of a defense in connection therewith) (i) the Notes, this Agreement,
any of the transactions contemplated herein or the actual or proposed use of the
proceeds of the Advances or (ii) the actual or alleged presence of Hazardous
Materials on any property of the Borrower or any of its Subsidiaries or any
Environmental Action relating in any way to the Borrower or any of its
Subsidiaries, except to the extent such claim, damage, loss, liability or
expense is found by a court of competent jurisdiction to have resulted from such
Indemnified Party's gross negligence or willful misconduct. In the case of an
investigation, litigation or other proceeding to which the indemnity in this
Section 8.04(b) applies, such indemnity shall be effective whether or not such
investigation, litigation or proceeding is brought by the Borrower, its
directors, equityholders or creditors or an Indemnified Party or any other
Person, whether or not any Indemnified Party is otherwise a party thereto and
whether or not the transactions contemplated hereby are consummated. The
Borrower also agrees not to assert any claim for special, indirect,
consequential or punitive damages against the Agent, any Lender, any of their
Affiliates, or any of their respective directors, officers, employees, attorneys
and agents, on any theory of liability, arising out of or otherwise relating to
the Notes, this Agreement, any of the transactions contemplated herein or the
actual or proposed use of the proceeds of the Advances.

                  (c) If any payment of principal of, or Conversion of, any
Eurodollar Rate Advance or LIBO Rate Advance is made by the Borrower to or for
the account of a Lender other than on the last day of the Interest Period for
such Advance, as a result of a payment or Conversion pursuant to Section 2.08(d)
or (e), 2.10 or 2.12, acceleration of the maturity of the Notes pursuant to
Section 6.01 or for any other reason, or by an Eligible Assignee to a Lender
other than on the last day of the Interest Period for such Advance upon an
assignment of rights and obligations under this Agreement pursuant to Section
8.07 as a result of a demand by the Borrower pursuant to Section 8.07(a), the
Borrower shall, upon demand by such Lender (with a copy of such demand to the
Agent), pay to the Agent for the account of such Lender any amounts required to
compensate such Lender for any additional losses, costs or expenses that it may
reasonably incur as a result of such payment or Conversion, including, without
limitation, any loss (excluding loss of anticipated profits), cost or expense
incurred by reason of the liquidation or reemployment of deposits or other funds
acquired by any Lender to fund or maintain such Advance.

                  (d) Without prejudice to the survival of any other agreement
of the Borrower hereunder, the agreements and obligations of the Borrower
contained in Sections 2.11, 2.14 and 8.04 shall survive the payment in full of
principal, interest and all other amounts payable hereunder and under the Notes.

                  SECTION 8.05. Right of Set-off. Upon (i) the occurrence and
during the continuance of any Event of Default and (ii) the making of the
request or the granting of the consent specified by Section 6.01 to authorize

                                       32
<PAGE>   38
and each of its Affiliates is hereby authorized at any time and from time to
time, to the fullest extent permitted by law, to set off and apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and other indebtedness at any time owing by such Lender or such Affiliate
to or for the credit or the account of the Borrower against any and all of the
obligations of the Borrower now or hereafter existing under this Agreement and
the Note held by such Lender, whether or not such Lender shall have made any
demand under this Agreement or such Note and although such obligations may be
unmatured. Each Lender agrees promptly to notify the Borrower after any such
set-off and application, provided that the failure to give such notice shall not
affect the validity of such set-off and application. The rights of each Lender
and its Affiliates under this Section are in addition to other rights and
remedies (including, without limitation, other rights of set-off) that such
Lender and its Affiliates may have.

                  SECTION 8.06. Binding Effect. This Agreement shall become
effective (other than Sections 2.01 and 2.03, which shall only become effective
upon satisfaction of the conditions precedent set forth in Section 3.01) when it
shall have been executed by the Borrower and the Agent and when the Agent shall
have been notified by each Initial Lender that such Initial Lender has executed
it and thereafter shall be binding upon and inure to the benefit of the
Borrower, the Agent and each Lender and their respective successors and assigns,
except that the Borrower shall not have the right to assign its rights hereunder
or any interest herein without the prior written consent of the Lenders.

                  SECTION 8.07. Assignments and Participations. (a) Each Lender
may and, if demanded by the Borrower (following a demand by such Lender pursuant
to Section 2.11 or 2.14) upon at least five Business Days' notice to such Lender
and the Agent, will assign to one or more Persons all or a portion of its rights
and obligations under this Agreement (including, without limitation, all or a
portion of its Commitment, the Revolving Credit Advances owing to it and the
Revolving Credit Note or Notes held by it); provided, however, that (i) each
such assignment shall be of a constant, and not a varying, percentage of all
rights and obligations under this Agreement (other than any right to make
Competitive Bid Advances, Competitive Bid Advances owing to it and Competitive
Bid Notes), (ii) except in the case of an assignment to a Person that,
immediately prior to such assignment, was a Lender or an assignment of all of a
Lender's rights and obligations under this Agreement, the amount of the
Commitment of the assigning Lender being assigned pursuant to each such
assignment (determined as of the date of the Assignment and Acceptance with
respect to such assignment) shall in no event be less than $10,000,000 or an
integral multiple of $1,000,000 in excess thereof, (iii) each such assignment
shall be to an Eligible Assignee, (iv) each such assignment made as a result of
a demand by the Borrower pursuant to this Section 8.07(a) shall be arranged by
the Borrower after consultation with the Agent and shall be either an assignment
of all of the rights and obligations of the assigning Lender under this
Agreement or an assignment of a portion of such rights and obligations made
concurrently with another such assignment or other such assignments that
together cover all of the rights and obligations of the assigning Lender under
this Agreement, (v) no Lender shall be obligated to make any such assignment as
a result of a demand by the Borrower pursuant to this Section 8.07(a) unless and
until such Lender shall have received one or more payments from either the
Borrower or one or more Eligible Assignees in an aggregate amount at least equal
to the aggregate outstanding principal amount of the Advances owing to such
Lender, together with accrued interest thereon to the date of payment of such
principal amount and all other amounts payable to such Lender under this
Agreement, and (vi) the parties to each such assignment shall execute and
deliver to the Agent, for its acceptance and recording in the Register, an
Assignment and Acceptance, together with any Revolving Credit Note subject to
such assignment and a processing and recordation fee of $3,500 payable by the
parties to each such assignment, provided, however, that in the case of each
assignment made as a result of a demand by the Borrower, such recordation fee
shall be payable by the Borrower except that no such recordation fee shall be
payable in the case of an assignment made at the request of the Borrower to an
Eligible Assignee that is an existing Lender, and (vii) any Lender may, without
the approval of the Borrower and the Agent, assign all or a portion of its
rights to any of its Affiliates. Upon such execution, delivery, acceptance and
recording, from and after the effective date specified in each Assignment and
Acceptance, (x) the assignee thereunder shall be a party hereto and, to the
extent that rights and obligations hereunder have been assigned to it pursuant
to such Assignment and Acceptance, have the rights and obligations of a Lender
hereunder and (y) the Lender assignor thereunder shall, to the extent that
rights and obligations hereunder have been assigned by it pursuant to such
Assignment and Acceptance, relinquish its rights (other than its rights under
Section 2.11, 2.14 and 8.04 to the extent any claim thereunder relates to an
event arising prior such assignment) and 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 Lender shall cease to be a party hereto).

                  (b) By executing and delivering an Assignment and Acceptance,
the Lender assignor thereunder and the assignee thereunder confirm to and agree
with each other and the other parties hereto as follows: (i) other than as
provided in such Assignment and Acceptance, such assigning Lender makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement or any other instrument or document
furnished pursuant hereto; (ii) such assigning Lender makes no representation or
warranty and assumes no responsibility with respect to the financial condition
of the Borrower or the performance or observance by the Borrower of any of its
obligations under this Agreement or any other instrument or document furnished
pursuant hereto; (iii) such assignee confirms that it has received a copy of
this Agreement, together with copies of the financial statements referred to in
Section 4.01 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such
Assignment and Acceptance; (iv) such assignee will, independently and without
reliance upon the Agent, such assigning Lender or any other Lender and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement; (v) such assignee confirms that it is an Eligible Assignee; (vi)
such assignee appoints and authorizes the Agent to take such action as agent on
its behalf and to exercise such powers and discretion under this Agreement as
are delegated to the Agent by the terms hereof, together with such powers and
discretion as are reasonably incidental thereto; and (vii) such assignee agrees
that it will perform in accordance with their terms all of the obligations that
by the terms of this Agreement are required to be performed by it as a Lender.

                  (c) Upon its receipt of an Assignment and Acceptance executed
by an assigning Lender and an assignee representing that it is an Eligible
Assignee, together with any Revolving Credit Note or Notes subject to such
assignment, the Agent shall, if such Assignment and Acceptance has been
completed and is in substantially the form of Exhibit C hereto, (i) accept such
Assignment and Acceptance, (ii) record the information contained therein in the
Register and (iii) give prompt notice thereof to the Borrower.

                  (d) The Agent shall maintain at its address referred to in
Section 8.02 a copy of each Assignment and Acceptance delivered to and accepted
by it and a register for the recordation of the names and addresses of the
Lenders and the Revolving Credit Commitment of, and principal amount of the
Advances owing to, each Lender from time to time (the "Register"). The entries
in the Register shall be conclusive and binding for all purposes, absent
manifest error, and the Borrower, the Agent and the Lenders may treat each
Person whose name is recorded in the Register as a Lender hereunder for all
purposes of this Agreement. The Register shall be available for inspection by
the Borrower or any Lender at any reasonable time and from time to time upon
reasonable prior notice.

                  (e) Each Lender may sell participations to one or more banks
or other entities (other than the Borrower or any of its Affiliates) in or to
all or a portion of its rights and obligations under this Agreement (including,
without limitation, all or a portion of its Revolving Credit Commitment, the
Advances owing to it and any Note or Notes held by it); provided, however, that
(i) such Lender's obligations under this Agreement (including, without
limitation, its Revolving Credit Commitment to the Borrower hereunder) shall
remain unchanged, (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, (iii) such Lender shall
remain the holder of any such Note for all purposes of this Agreement, (iv) the
Borrower, the Agent and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and (v) no participant under any such
participation shall have any right to approve any amendment or waiver of any
provision of this Agreement or any Note, or any consent to any departure by the
Borrower therefrom, except to the extent that such amendment, waiver or consent
would reduce the principal of, or interest on, the Notes or any fees or other
amounts payable hereunder, in each case to the extent subject to such
participation, or postpone any date fixed for any payment of principal of, or
interest on, the Notes or any fees or other amounts payable hereunder, in each
case to the extent subject to such participation.

                  (f) Any Lender may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
8.07, disclose to the assignee or participant or proposed assignee or
participant, any information relating to the Borrower furnished to such Lender
by or on behalf of the Borrower; provided that, prior to any such disclosure,
the assignee or participant or proposed assignee or participant shall agree to
preserve the confidentiality of any Confidential Information relating to the
Borrower received by it from such Lender.

<PAGE>   40
                  (g) Notwithstanding any other provision set forth in this
Agreement, any Lender may at any time create a security interest in all or any
portion of its rights under this Agreement (including, without limitation, the
Advances owing to it and any Note or Notes held by it) in favor of any Federal
Reserve Bank in accordance with Regulation A of the Board of Governors of the
Federal Reserve System.

                  SECTION 8.08. Confidentiality. Neither the Agent nor any
Lender shall disclose any Confidential Information to any other Person without
the consent of the Borrower, other than (a) to the Agent's or such Lender's
Affiliates and their officers, directors, employees, agents and advisors and, as
contemplated by Section 8.07(f), to actual or prospective assignees and
participants, and then only on a confidential basis, (b) as required by any law,
rule or regulation or judicial process and (c) as requested or required by any
state, federal or foreign authority or examiner regulating banks or banking.

                  SECTION 8.09. Governing Law. This Agreement and the Notes
shall be governed by, and construed in accordance with, the laws of the State of
New York.

                  SECTION 8.10. Execution in Counterparts. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement. Delivery of an executed counterpart of a signature page to this
Agreement by telecopier shall be effective as delivery of a manually executed
counterpart of this Agreement.

                  SECTION 8.11. Jurisdiction, Etc. (a) Each of the parties
hereto hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of any New York State court or
federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement or the Notes, or for recognition or enforcement of
any judgment, and each of the parties hereto hereby irrevocably and
unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in any such New York State court or, to
the extent permitted by law, in such federal court. The Borrower hereby agrees
that service of process in any such action or proceeding brought in the any such
New York State court or in such federal court may be made by the mailing thereof
by any parties hereto by registered or certified mail, postage prepaid, to the
Borrower at its address specified pursuant to Section 8.02. Each of the parties
hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Agreement shall affect any
right that any party may otherwise have to bring any action or proceeding
relating to this Agreement or the Notes in the courts of any jurisdiction.

                  (b) Each of the parties hereto irrevocably and unconditionally
waives, to the fullest extent it may legally and effectively do so, any
objection that it may now or hereafter have to the laying of venue of any suit,
action or proceeding arising out of or relating to this Agreement or the Notes
in any New York State or federal court. Each of the parties hereto hereby
irrevocably waives, to the fullest extent permitted by law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such
court.

                  SECTION 8.12. Waiver of Jury Trial. Each of the Borrower, the
Agent and the Lenders hereby irrevocably waives all right to trial by jury in
any action, proceeding or counterclaim (whether based on contract, tort or
otherwise) arising out of or relating to this Agreement or the Notes or the
actions of the Agent or any Lender in the negotiation, administration,
performance or enforcement thereof.

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

Ladies and Gentlemen:

                  This opinion is furnished to you pursuant to Section
3.01(h)(iv) of the 364-Day Credit Agreement, dated as of May 29, 2001 (the
"Credit Agreement"), among York International Corporation (the "Borrower"), the
Lenders parties thereto and Citibank, N.A., as Agent for said Lenders. Terms
defined in the Credit Agreement are used herein as therein defined.

                  We have acted as counsel for the Borrower in connection with
the preparation, execution and delivery of the Credit Agreement.

                  In that connection, we have examined:

                  (1) The Credit Agreement.

                  (2) The documents furnished by the Borrower pursuant to
         Article III of the Credit Agreement.

                  (3) The [Articles] [Certificate] of Incorporation of the
         Borrower and all amendments thereto (the "Charter").

                  (4) The by-laws of the Borrower and all amendments thereto
         (the "By-laws").

                  (5) A certificate of the Secretary of State of Delaware, dated
         _______________, 2001, attesting to the continued corporate existence
         and good standing of the Borrower in that State.

We have also examined the originals, or copies certified to our satisfaction, of
the documents listed in a certificate of the chief financial officer of the
Borrower, dated the date hereof (the "Certificate"), certifying that the
documents listed in such certificate are all of the indentures, loan or credit
agreements, leases, guarantees, mortgages, security agreements, bonds, notes and
other agreements or instruments, and all of the orders, writs, judgments,
awards, injunctions and decrees, that affect or purport to affect the Borrower's
right to borrow money or the Borrower's obligations under the Credit Agreement
or the Notes. In addition, we have examined the originals, or copies certified
to our satisfaction, of such other corporate records of the Borrower,
certificates of public officials and of officers of the Borrower, and
agreements, instruments and other documents, as we have deemed necessary as a
basis

for the opinions expressed below. As to questions of fact material to such
opinions, we have, when relevant facts were not independently established by us,
relied upon certificates of the Borrower or its officers or of public officials.
We have assumed the due execution and delivery, pursuant to due authorization,
of the Credit Agreement by the Initial Lenders and the Agent.

                  Our opinions expressed below are limited to the law of the
State of [New York], the General Corporation Law of the State of Delaware and
the Federal law of the United States.

                  Based upon the foregoing and upon such investigation as we
have deemed necessary, we are of the following opinion:

                  1. The Borrower is a corporation duly organized, validly
         existing and in good standing under the laws of the State of Delaware.

                  2. The execution, delivery and performance by the Borrower of
         the Credit Agreement and the Notes, and the consummation of the
         transactions contemplated thereby, are within the Borrower's corporate
         powers, have been duly authorized by all necessary corporate action,
         and do not contravene (i) the Charter or the By-laws or (ii) any law,
         rule or regulation applicable to the Borrower (including, without
         limitation, Regulation X of the Board of Governors of the Federal
         Reserve System) or (iii) any contractual or legal restriction contained
         in any document listed in the Certificate or, to the best of our
         knowledge, contained in any other similar document. The Credit
         Agreement and the Notes have been duly executed and delivered on behalf
         of the Borrower.

                  3. No authorization, approval or other action by, and no
         notice to or filing with, any governmental authority or regulatory body
         or any other third party is required for the due execution, delivery
         and performance by the Borrower of the Credit Agreement and the Notes.

                  4. The Credit Agreement is, and after giving effect to the
         initial Borrowing, the Notes will be, legal, valid and binding
         obligations of the Borrower enforceable against the Borrower in
         accordance with their respective terms.

                  5. To the best of our knowledge, there are no pending or
         overtly threatened actions or proceedings against the Borrower or any
         of its Subsidiaries before any court, governmental agency or arbitrator
         that purport to affect the legality, validity, binding effect or
         enforceability of the Credit Agreement or any of the Notes or the
         consummation of the transactions contemplated thereby or[, except as
         described in Exhibit 3.01(b) to the Credit Agreement,] that are likely
         to have a materially adverse effect upon the financial condition or
         operations of the Borrower or any of its Subsidiaries.

                  **[6. In any action or proceeding arising out of or relating
         to the Credit Agreement or the Notes in any court of the State of
         _______________ or in any Federal court sitting in the State of
         _______________, such court would recognize and give effect to the
         provisions of Section 8.09 of the Credit Agreement wherein the parties
         thereto agree that the Credit Agreement and the Notes shall be governed
         by, and construed in accordance with, the laws of the State of New
         York. Without limiting the generality of the foregoing, a court of the
         State of _______________ or a Federal court sitting in the State of
         _______________ would apply the usury law of the State of New York, and
         would not apply the usury law of the State of _______________, to the
         Credit Agreement and the Notes. However, if a court of the State of
         _______________ or a Federal court sitting in the State of
         _______________ were to hold that the Credit Agreement and the Notes
         are governed by, and to be construed in accordance with, the laws of
         the State of _______________, the Credit Agreement and the Notes would
         be, under the laws of the State of




**       Another alternative to be considered if Borrower's counsel is not
         prepared to opine as to New York law, and the Initial Lenders are not
         prepared to require a separate opinion of special New York counsel for
         the Borrower. If this alternative is used, paragraph 4 would be
         eliminated.

         _______________, legal, valid and binding obligations of the Borrower
         enforceable against the Borrower in accordance with their respective
         terms.]

                  The opinions set forth above are subject to the following
         qualifications:

                  (a) Our opinion in paragraph 4 above* as to enforceability is
         subject to the effect of any applicable bankruptcy, insolvency
         (including, without limitation, all laws relating to fraudulent
         transfers), reorganization, moratorium or similar law affecting
         creditors' rights generally.

                  (b) Our opinion in paragraph 4 above** as to enforceability is
         subject to the effect of general principles of equity, including,
         without limitation, concepts of materiality, reasonableness, good faith
         and fair dealing (regardless of whether considered in a proceeding in
         equity or at law).

                  (c) We express no opinion as to (i) Section 2.15 of the Credit
         Agreement insofar as it provides that any Lender purchasing a
         participation from another Lender pursuant thereto may exercise set-off
         or similar rights with respect to such participation and (ii) the
         effect of the law of any jurisdiction other than the State of
         _______________ wherein any Lender may be located or wherein
         enforcement of the Credit Agreement or the Notes may be sought that
         limits the rates of interest legally chargeable or collectible.

                                              Very truly yours,



*        If paragraph 6 is used, this should be modified to refer to "the last
         sentence of paragraph 6 above".
