                  funding for such Revolving Credit Borrowing with such Interest
                  Period (the failure of any Lender to so respond by such time

                  months;

                      (iv) whenever the last day of any Interest Period would
                  otherwise occur on a day other than a Business Day, the 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 occurs
                  on a day of an initial calendar month for which there is no
                  numerically corresponding day in the calendar month that

Revolving Credit Borrowing shall be made on notice, given not later than (x)
11:00 A.M. (New York City time) on the third Business Day prior to the date of
the proposed Revolving Credit Borrowing in the case of a Revolving Credit
Borrowing consisting of Eurodollar Rate Advances or (y) 11:00 A.M. (New York
City time) on the date of the proposed Revolving Credit Borrowing in the case of
a Revolving Credit Borrowing consisting of Base Rate Advances, by the Borrower

telecopier or telex. Each such notice of a Revolving Credit Borrowing (a "Notice
of Revolving Credit Borrowing") shall be by telephone, confirmed immediately in
writing, or telecopier or telex in substantially the form of Exhibit B-1 hereto,
specifying therein the requested (i) date of such Revolving Credit Borrowing,
(ii) Type of Advances comprising such Revolving Credit Borrowing, (iii)
aggregate amount of such Revolving Credit Borrowing, and (iv) in the case of a
Revolving Credit Borrowing consisting of Eurodollar Rate Advances, initial
Interest Period for each such Revolving Credit Advance. Each Lender shall,
before 12:00 noon (New York City time) on the date of such Revolving Credit
Borrowing make available for the account of its Applicable Lending Office to the
Agent at the Agent's Account, in same day funds, such Lender's ratable portion
of such Revolving Credit Borrowing. After the Agent's receipt of such funds and
upon fulfillment of the applicable conditions set forth in Article III, the
Agent will make such funds available to the Borrower at the Agent's address
referred to in Section 8.02, provided, however, that the Agent shall first make
a portion of such funds equal to the aggregate principal amount of any Letter of
Credit Advances made by the Issuing Bank and by any other Lender and outstanding
on the date of such Revolving Credit Borrowing, plus interest accrued and unpaid
thereon to and as of such date, available to the Issuing Bank and such other
Lender for repayment of such Letter of Credit Advances.

                  (b) Anything in subsection (a) above to the contrary
notwithstanding, (i) the Borrower may not select Eurodollar Rate Advances for
any Revolving Credit Borrowing if the aggregate amount of such Revolving Credit
Borrowing is less than $10,000,000 or if the obligation of the Lenders to make
Eurodollar Rate Advances

                                       12
<PAGE>   18
shall then be suspended pursuant to Section 2.09 or 2.13 and (ii) the Eurodollar
Rate Advances may not be outstanding as part of more than ten separate Revolving
Credit Borrowings.

                  (c) Each Notice of Revolving Credit Borrowing shall be
irrevocable and binding on the Borrower. In the case of any Revolving Credit
Borrowing that the related Notice of Revolving Credit Borrowing specifies is to
be comprised of Eurodollar Rate Advances, 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 such Notice of
Revolving Credit Borrowing for such Revolving Credit 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 Revolving Credit Advance to be made by such Lender as part of
such Revolving Credit Borrowing when such Revolving Credit Advance, as a result
of such failure, is not made on such date.

                  (d) Unless the Agent shall have received notice from a Lender
prior to the date of any Revolving Credit Borrowing that such Lender will not
make available to the Agent such Lender's ratable portion of such Revolving
Credit Borrowing, the Agent may assume that such Lender has made such portion
available to the Agent on the date of such Revolving Credit Borrowing in
accordance with subsection (a) of this Section 2.02 and the Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount. If and to the extent that such Lender shall not have so
made such ratable portion available to the Agent, such Lender and the Borrower
severally agree to repay to the Agent forthwith on demand such corresponding
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

                                       13
<PAGE>   19
         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 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.

                                       14
<PAGE>   20

                  (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 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,

                                       15
<PAGE>   21
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. Issuance of and Drawings and Reimbursement Under
the Letters of Credit. (a) Request for Issuance. Each Letter of Credit shall be
issued upon notice, given not later than 11:00 A.M. (New York City time) on the
third Business Day prior to the date of the proposed issuance of such Letter of
Credit, by the Borrower to the Issuing Bank, which shall give to the Agent and
each Lender prompt notice thereof by telex or telecopier. Each such notice of
issuance of a Letter of Credit (a "Notice of Issuance") shall be by telephone,
confirmed immediately in writing, or telex or telecopier, specifying therein the
requested (A) date of such issuance (which shall be a Business Day), (B)
Available Amount of such Letter of Credit, (C) expiration date of such Letter of
Credit, (D) name and address of the beneficiary of such Letter of Credit and (E)
form of such Letter of Credit, and shall be accompanied by such application and
agreement for letter of credit as the Issuing Bank may specify to the Borrower
for use in connection with such requested Letter of Credit (a "Letter of Credit
Agreement"). If the requested form of such Letter of Credit is acceptable to the
Issuing Bank in its sole discretion, the Issuing Bank will, upon fulfillment of
the applicable conditions set forth in Article III, make such Letter of Credit
available to the Borrower at its office referred to in Section 8.02 or as
otherwise agreed with the Borrower in connection with such issuance. In the
event and to the extent that the provisions of any Letter of Credit Agreement
shall conflict with this Agreement, the provisions of this Agreement shall
govern.

                  (b) Letter of Credit Reports. The Issuing Bank shall furnish
to the Agent, the Borrower and each Lender Party on the first Business Day of
each calendar quarter a written report setting forth the average daily aggregate
Available Amount during the preceding calendar quarter of all Letters of Credit.

                  (c) Drawing and Reimbursement. The payment by the Issuing Bank
of a draft drawn under any Letter of Credit shall constitute for all purposes of
this Agreement the making by the Issuing Bank of a letter of credit advance (a
"Letter of Credit Advance"), which shall be a Base Rate Advance, in the amount
of such draft. Upon written demand by the Issuing Bank with an outstanding
Letter of Credit Advance, with a copy of such demand to the Agent, each Lender
shall purchase from the Issuing Bank, and the Issuing Bank shall sell and assign
to each such Lender, such Lender's Ratable Share of such outstanding Letter of
Credit Advance as of the date of such purchase, by making available for the
account of its Applicable Lending Office to the Agent for the account of the
Issuing Bank, by deposit to the Agent's Account, in same day funds, an amount
equal to the portion of the outstanding principal amount of such Letter of
Credit Advance to be purchased by such Lender. Promptly after receipt thereof,
the Agent shall transfer such funds to the Issuing Bank. The Borrower hereby
agrees to each such sale and assignment. Each Lender agrees to purchase its
Ratable Share of an outstanding Letter of Credit Advance on (i) the Business Day
on which demand therefor is made by the Issuing Bank, provided that notice of
such demand is given not later than 11:00 A.M. (New York City time) on such
Business Day, or (ii) the first Business Day next succeeding such demand if
notice of such demand is given after such time. Upon any such assignment by the
Issuing Bank to any Lender of a portion of a Letter of Credit Advance, the
Issuing Bank represents and warrants to such other Lender that the Issuing Bank
is the legal and beneficial owner of such interest being assigned by it, free
and clear of any liens, but makes no other representation or warranty and
assumes no responsibility with respect to such Letter of Credit Advance, this
Agreement or the Borrower. If and to the extent that any Lender shall not have
so made the amount of such Letter of Credit Advance available to the Agent, such
Lender agrees to pay to the Agent forthwith on demand such amount together with
interest thereon, for each day from the date of demand by the Issuing Bank until
the date such amount is paid to the Agent, at the Federal Funds Rate for its
account or the account of the Issuing Bank, as applicable. If such Lender shall
pay to the Agent such amount for the account of the Issuing Bank on any Business
Day, such amount so paid in respect of principal shall constitute a Letter of
Credit Advance

                                       16
<PAGE>   22
made by such Lender on such Business Day for purposes of this Agreement, and the
outstanding principal amount of the Letter of Credit Advance made by the Issuing
Bank shall be reduced by such amount on such Business Day.

                  (d) Failure to Make Letter of Credit Advances. The failure of
any Lender to make the Letter of Credit Advance to be made by it on the date
specified in Section 2.04(c) shall not relieve any other Lender of its
obligation hereunder to make its Letter of Credit Advance on such date, but no
Lender shall be responsible for the failure of any other Lender to make the
Letter of Credit Advance to be made by such other Lender on such date.

                  SECTION 2.05. 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) Letter of Credit Fees, Etc. (i) The Borrower shall pay to
the Agent for the account of each Lender a commission, payable in arrears
quarterly on the last day of each March, June, September and December commencing
June 30, 2001, and on the earliest to occur of the full drawing, expiration,
termination or cancellation of any Letter of Credit and on the Termination Date,
on such Lender's Ratable Share of the average daily aggregate Available Amount
during such quarter of all Letters of Credit outstanding from time to time at
the rate per annum equal to the Applicable Margin for Eurodollar Rate Advances
plus the Applicable Utilization Fee, if any, plus, after the occurrence and
during the continuance of an Event of Default under Section 6.01(a), 2% per
annum.

                  (ii) The Borrower shall pay to the Issuing Bank, for its own
         account, such commissions, issuance fees, fronting fees, transfer fees
         and other fees and charges in connection with the issuance or
         administration of each Letter of Credit as the Borrower and the Issuing
         Bank shall agree.

                  (c) 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 2.06. Termination or Reduction of the Commitments. (a)
Optional. 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.

                  (b) Mandatory. The Letter of Credit Facility shall be
permanently reduced from time to time on the date of each reduction in the
Revolving Credit Commitments by the amount, if any, by which the amount of the
Letter of Credit Commitment exceeds the Revolving Credit Facility after giving
effect to such reduction of the Revolving Credit Facility.

                  SECTION 2.07. Repayment of Advances. (a) 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.

                  (b) Letter of Credit Advances. (i) The Borrower shall repay to
the Agent for the account of the Issuing Bank and each other Lender that has
made a Letter of Credit Advance on the earlier of demand and the Termination
Date the outstanding principal amount of each Letter of Credit Advance made by
each of them.

                  (ii) The obligations of the Borrower under this Agreement, any
         Letter of Credit Agreement and any other agreement or instrument
         relating to any Letter of Credit shall be unconditional and
         irrevocable, and shall be paid strictly in accordance with the terms of
         this Agreement, such Letter of Credit Agreement and such other
         agreement or instrument under all circumstances, including, without
         limitation, the following circumstances:

                           (A) any lack of validity or enforceability or this
                  Agreement, any Letter of Credit Agreement, any Letter of
                  Credit or any other agreement or instrument relating thereto
                  (all of the foregoing being, collectively, the "L/C Related
                  Documents");

                           (B) any change in the time, manner or place of
                  payment of, or in any other term of, all or any of the
                  obligations of the Borrower in respect of any L/C Related
                  Document or any other amendment or waiver of or any consent to
                  departure from all or any of the L/C Related Documents;

                           (C) the existence of any claim, set-off, defense or
                  other right that the Borrower may have at any time against any
                  beneficiary or any transferee of a Letter of Credit (or any
                  Persons for which any such beneficiary or any such transferee
                  may be acting), the Issuing Bank or any other Person, whether
                  in connection with the transactions contemplated by the L/C
                  Related Documents or any unrelated transaction;

                           (D) any statement or any other document presented
                  under a Letter of Credit proving to be forged, fraudulent,

                  Credit;

                           (F) any exchange, release or non-perfection of any
                  collateral, or any release or amendment or waiver of or

                  whether or not similar to any of the foregoing, including,
                  without limitation, any other circumstance that might
                  otherwise constitute a defense to, or a discharge of, the
                  Borrower or any guarantor.

                  SECTION 2.08. Interest on Revolving Credit Advances and Letter
of Credit Advances. (a) Scheduled Interest. The Borrower shall pay interest on
the unpaid principal amount of each Advance (other than a Competitive Bid
Advance) owing to each Lender from the date of such 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 and each Letter of Credit Advance owing to each Lender
Party, payable in arrears on the dates referred to in clause (a)(i) or

                                       18
<PAGE>   24
(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 2.09. 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 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 2.08(a)(i) or (ii), and the rate, if any, furnished by each Reference
Bank for the purpose of determining the interest rate under Section 2.08(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.

                                       19

                  SECTION 2.10. 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
2.09 and 2.13, 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 (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 2.11. Prepayments of Revolving Credit Advances and
Letter of 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 or the Letter of Credit Advances 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. (i) 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 and the Letter
         of Credit Advances equal to the amount by which (A) the sum of the
         aggregate principal amount of the Advances then outstanding plus the
         aggregate Available Amount of all Letters of Credit then outstanding
         exceeds (B) the Revolving Credit Facility on such Business Day.

                  (ii) The Borrower shall, on each Business Day, pay to the
         Agent for deposit in the L/C Cash Collateral Account an amount
         sufficient to cause the aggregate amount on deposit in such Account to
         equal the amount by which the aggregate Available Amount of all Letters
         of Credit then outstanding exceeds the Letter of Credit Facility on
         such Business Day.

                  SECTION 2.12. 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 Party of agreeing to make
or making, funding or maintaining Eurodollar Rate Advances or LIBO Rate Advances
or of agreeing to issue or of issuing or maintaining Letters of Credit or of
agreeing to make or of making or maintaining Letter of Credit Advances
(excluding for purposes of this Section 2.12 any such increased costs resulting
from (i) Taxes or Other Taxes (as to which Section 2.15 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 Party 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 Party (with a copy of such demand to the Agent), pay to
the Agent for the account of such Lender Party additional amounts sufficient to
compensate such Lender Party 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 Party, shall be
conclusive and binding for all purposes, absent manifest error.

                  (b) If any Lender Party 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)

                                       20
<PAGE>   26
affects or would affect the amount of capital required or expected to be
maintained by such Lender Party or any corporation controlling such Lender Party
and that the amount of such capital is increased by or based upon the existence
of such Lender Party's commitment to lend or to issue Letters of Credit
hereunder and other commitments of such type or the issuance or maintenance of
the Letters of Credit (or similar contingent obligations), then, upon demand by
such Lender Party (with a copy of such demand to the Agent), the Borrower shall
pay to the Agent for the account of such Lender Party, from time to time as
specified by such Lender Party, additional amounts sufficient to compensate such
Lender Party or such corporation in the light of such circumstances, to the
extent that such Lender Party reasonably determines such increase in capital to
be allocable to the existence of such Lender Party's commitment to lend
hereunder. A certificate as to such amounts submitted to the Borrower and the
Agent by such Lender Party 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 2.12 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 2.13. 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 2.08(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 2.14. 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, interest, facility fees or Letter of Credit commissions
ratably (other than amounts payable pursuant to Section 2.03, 2.12, 2.15 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 and Letter of Credit commissions 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,

                                       21
<PAGE>   27
facility fees or Letter of Credit commissions 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, facility fee or
Letter of Credit commissions, 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.

                  SECTION 2.15. Taxes. (a) Any and all payments by the Borrower
to or for the account of any Lender Party or the Agent hereunder or under the
Notes or any other documents to be delivered hereunder shall be made, in
accordance with Section 2.14 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 Party
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 Party or the Agent (as the case may be) is organized or any
political subdivision thereof and, in the case of each Lender Party, 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 Party'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 Party 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
2.15) such Lender Party 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 Party 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 2.15) imposed on or paid by
such Lender Party 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
Party 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

                                       22
<PAGE>   28
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 Party 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 Party and on
the date of the Assumption Agreement or the Assignment and Acceptance pursuant
to which it becomes a Lender Party in the case of each other Lender Party, and
from time to time thereafter as reasonably requested in writing by the Borrower
(but only so long as such Lender Party 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 Party 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 Party at the time such Lender Party 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 Party 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 Party assignee becomes a party to this Agreement, the
Lender Party 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 Party 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 Party
reasonably considers to be confidential, the Lender Party 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 Party has
failed to provide the Borrower with the appropriate form, certificate or other
document described in Section 2.15(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 Party shall
not be entitled to indemnification under Section 2.15(a) or (c) with respect to
Taxes imposed by the United States by reason of such failure; provided, however,
that should a Lender Party 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 Party shall reasonably request to assist the
Lender Party to recover such Taxes.

                  SECTION 2.16. Sharing of Payments, Etc. If any Lender Party
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 or Letter of Credit Advances owing to it (other than pursuant to
Section 2.12, 2.15 or 8.04(c)) in excess of its ratable share of payments on
account of the Revolving Credit Advances and Letter of Credit Advances obtained
by all the Lender Parties, such Lender Party shall forthwith purchase from the
other Lender Parties such participations in the Revolving Credit Advances owing
to them as shall be necessary to cause such purchasing Lender Party 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 Party, such purchase from each Lender Party shall be rescinded and such
Lender Party shall repay to the purchasing Lender Party the purchase price to
the extent of such recovery together with an amount equal to such Lender Party's
ratable share (according to the proportion of (i) the amount of such Lender
Party's required repayment to (ii) the total amount so recovered from the
purchasing Lender Party) of any interest or other amount paid or payable by the
purchasing Lender Party in respect of the total amount so recovered. The
Borrower agrees that any Lender Party so purchasing a participation from another
Lender Party pursuant to this Section 2.16 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 Party were the direct
creditor of the Borrower in the amount of such participation.

                                       23
<PAGE>   29

                  SECTION 2.17. 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 and Letter of 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 and Letter
of 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 and Letter of 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)

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 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 5.01. Affirmative Covenants. So long as any Advance
shall remain unpaid, any Lender Party shall have any Commitment hereunder or any
Letter of Credit shall be outstanding, 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.

                  (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 Lender
         Parties.

                  (e) Visitation Rights. At any reasonable time and from time to
         time upon reasonable notice, permit the Agent or any of the Lender
         Parties 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.

            (i)   Reporting Requirements.  Furnish to the Lender Parties:

                  (i) as soon as available and in any event within 45 days after

            officer or treasurer of the Borrower as having been prepared in

            of any change in generally accepted accounting principles used in
            the preparation of such financial statements, the Borrower shall
            also provide, if necessary for the determination of compliance with
            Section 5.03, a statement of reconciliation conforming such
            financial statements to GAAP;

            exception, or qualification arising out of the scope of the audit,
            acceptable to the Required Lenders by KPMG LLP or other independent
            public accountants of nationally recognized standing and
            certificates of the chief financial officer or treasurer of the
            Borrower as to compliance with the terms of this Agreement and

      (as the case may be), when the same becomes due and payable (whether by
      scheduled maturity, required prepayment, acceleration, demand or
      otherwise), and such failure shall continue 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 such Debt and shall continue after
      the applicable grace period, if any, specified in such agreement or
      instrument, if the effect of such event or condition is to accelerate, or
      to permit the acceleration of, the maturity of such Debt; or any such Debt

      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
      $25,000,000 in the aggregate shall be rendered against the Borrower or any
      of its Subsidiaries and either (i) enforcement proceedings shall have been

      such 24-month period 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

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 (other than Letter of Credit

                                       32
<PAGE>   38
Advances by the Issuing Bank or a Lender pursuant to Section 2.04(c)) and of the
Issuing Bank to issue Letters of Credit 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 (other than Letter of Credit Advances by the Issuing Bank or a
Lender under Section 2.04(c)) and of the Issuing Bank to issue Letters of Credit
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.

            SECTION 6.02. Actions in Respect of the Letters of Credit upon
Default. If any Event of Default shall have occurred and be continuing, the
Agent may with the consent, or shall at the request, of the Required Lenders,
irrespective of whether it is taking any of the actions described in Section
6.01 or otherwise, make demand upon the Borrower to, and forthwith upon such
demand the Borrower will (a) pay to the Agent on behalf of the Lender Parties in
same day funds at the Agent's office designated in such demand, for deposit in
the L/C Cash Collateral Account, an amount equal to the aggregate Available
Amount of all Letters of Credit then outstanding or (b) make such other
arrangements in respect of the outstanding Letters of Credit as shall be
acceptable to the Required Lenders. If at any time the Agent determines that any
funds held in the L/C Cash Collateral Account are subject to any right or claim
of any Person other than the Agent and the Lender Parties or that the total
amount of such funds is less than the aggregate Available Amount of all Letters
of Credit, the Borrower will, forthwith upon demand by the Agent, pay to the
Agent, as additional funds to be deposited and held in the L/C Cash Collateral
Account, an amount equal to the excess of (a) such aggregate Available Amount
over (b) the total amount of funds, if any, then held in the L/C Cash Collateral
Account that the Agent determines to be free and clear of any such right and
claim. Upon the drawing of any Letter of Credit for which funds are on deposit
in the L/C Cash Collateral Account, such funds shall be applied to reimburse the
Issuing Bank or Lenders, as applicable, to the extent permitted by applicable
law.

                                   ARTICLE VII

                                    THE AGENT

            SECTION 7.01. Authorization and Action. Each Lender Party 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 instructions of
the Required Lenders, and such instructions shall be binding upon all Lender
Parties 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 Party 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 Party and shall not be
responsible to any Lender Party 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,

                                       33
<PAGE>   39
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 Party 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 Party
and may exercise the same as though it were not the Agent; and the term "Lender
Party" or "Lender Parties" 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
Lender Parties. 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 Party Credit Decision. Each Lender Party
acknowledges that it has, independently and without reliance upon the Agent or
any other Lender Party 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 Party also acknowledges that it will, independently and
without reliance upon the Agent or any other Lender Party 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. (a) The Lender Parties agree to
indemnify the Agent (to the extent not reimbursed by the Borrower) from and
against such Lender Party'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 Party
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 Party 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 Costs, this Section 7.05 applies whether any such investigation,
litigation or proceeding is brought by the Agent, any Lender Party or a third
party.

            (b) The Lender Parties agree to indemnify the Issuing Bank (to the
extent not promptly reimbursed by the Borrower) from and against such Lender
Party'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 Issuing Bank in any way relating to or arising out of this Agreement
and its related documents and instruments or any action taken or omitted by the
Issuing Bank under this Agreement and its related documents and instruments;
provided, however, that no Lender Party shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from the Issuing Bank's gross
negligence or willful misconduct as found by a court of competent jurisdiction.
Without limitation of the foregoing, the Lender Parties agree to reimburse the
Issuing Bank promptly upon demand for its ratable share of any costs and
expenses (including, without limitation, fees and expenses of counsel) payable
by the Borrower under Section 8.04, to the extent that the Issuing Bank is not
promptly reimbursed for such costs and expenses by the Borrower.

            SECTION 7.06. Successor Agent. The Agent may resign at any time by
giving written notice thereof to the Lender Parties 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
Lender Parties, 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 Party 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 Party.

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

provided further that (x) 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

signed by the Issuing Bank in addition to the Lenders required above to take
such action, affect the rights or obligations of the Issuing Bank under this
Agreement.

provided for hereunder shall be in writing (including telecopier, telegraphic or

            SECTION 8.03. No Waiver; Remedies. No failure on the part of any
Lender Party 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 Lender Parties, 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 Party 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 Party 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 the Letters of Credit 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 Party, 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 or the
Letters of Credit.

            (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 Party other than on the last day of the Interest Period for such
Advance, as a result of a payment or Conversion pursuant to Section 2.09(d) or
(e), 2.11 or 2.13, 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 2.12, 2.15 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

                                       36
<PAGE>   42
authorize the Agent to declare the Notes due and payable pursuant to the
provisions of Section 6.01, each Lender Party 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 Party 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 Party, whether or not such Lender Party shall have made any demand
under this Agreement or such Note and although such obligations may be
unmatured. Each Lender Party 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 Party 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 Party 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 Party that such Initial Lender Party
has executed it and thereafter shall be binding upon and inure to the benefit of
the Borrower, the Agent and each Lender Party 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
Lender Parties.

            SECTION 8.07. Assignments and Participations. (a) Each Lender Party
may and, if demanded by the Borrower (following a demand by such Lender Party
pursuant to Section 2.12 or 2.15) upon at least five Business Days' notice to
such Lender Party 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 Party or an
assignment of all of a Lender Party's rights and obligations under this
Agreement, the amount of the Commitment of the assigning Lender Party 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 Party 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 Party under this Agreement, (v) no Lender Party 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 Party 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 Party, together with
accrued interest thereon to the date of payment of such principal amount and all
other amounts payable to such Lender Party 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 Party, and (vii) any Lender Party 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 or Issuing Bank, as
the case may be, hereunder and (y) the Lender or Issuing Bank 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 2.12, 2.15 and 8.04 to the extent any claim
thereunder relates to an event arising prior such assignment) and be released
from its obligations

                                       37
<PAGE>   43
under this Agreement (and, in the case of an Assignment and Acceptance covering
all or the remaining portion of an assigning Lender's or Issuing Bank's rights
and obligations under this Agreement, such Lender or Issuing Bank shall cease to
be a party hereto).

            (b) By executing and delivering an Assignment and Acceptance, the
Lender Party 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 Party 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 Party 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 Party
or any other Lender Party 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 or Issuing Bank, as the case may be.

            (c) Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender Party 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 Lender
Parties and the Revolving Credit Commitment of, and principal amount of the
Advances owing to, each Lender Party 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 Lender Parties may treat
each Person whose name is recorded in the Register as a Lender Party hereunder
for all purposes of this Agreement. The Register shall be available for
inspection by the Borrower or any Lender Party at any reasonable time and from
time to time upon reasonable prior notice.

            (e) Each Lender Party 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 Party's obligations under this Agreement (including, without
limitation, its Revolving Credit Commitment to the Borrower hereunder) shall
remain unchanged, (ii) such Lender Party shall remain solely responsible to the
other parties hereto for the performance of such obligations, (iii) such Lender
Party shall remain the holder of any such Note for all purposes of this
Agreement, (iv) the Borrower, the Agent and the other Lender Parties shall
continue to deal solely and directly with such Lender Party in connection with
such Lender Party'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.

                                       38
<PAGE>   44
            (f) Any Lender Party 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
Party 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 Party.

            (g) The Issuing Bank may assign to one or more Eligible Assignees
all or a portion of its rights and obligations under the undrawn portion of its
Letter of Credit Commitment at any time; provided, however, that (i) each such
assignment shall be to an Eligible Assignee and (ii) 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 a
processing and recordation fee of $3,500.

            (h) Notwithstanding any other provision set forth in this Agreement,
any Lender Party 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
Party 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
Party'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. No Liability of the Issuing Bank. The Borrower assumes
all risks of the acts or omissions of any beneficiary or transferee of any
Letter of Credit with respect to its use of such Letter of Credit. Neither the
Issuing Bank nor any of its officers or directors shall be liable or responsible
for: (a) the use that may be made of any Letter of Credit or any acts or
omissions of any beneficiary or transferee in connection therewith; (b) the
validity, sufficiency or genuineness of documents, or of any endorsement
thereon, even if such documents should prove to be in any or all respects
invalid, insufficient, fraudulent or forged; (c) payment by the Issuing Bank
against presentation of documents that do not comply with the terms of a Letter
of Credit, including failure of any documents to bear any reference or adequate
reference to the Letter of Credit; or (d) any other circumstances whatsoever in
making or failing to make payment under any Letter of Credit, except that the
Borrower shall have a claim against the Issuing Bank, and the Issuing Bank shall
be liable to the Borrower, to the extent of any direct, but not consequential,
damages suffered by the Borrower that the Borrower proves were caused by (i) the
Issuing Bank's willful misconduct or gross negligence as determined by a court
of competent jurisdiction in determining whether documents presented under any
Letter of Credit comply with the terms of the Letter of Credit or (ii) the
Issuing Bank's willful failure to make lawful payment under a Letter of Credit
after the presentation to it of a draft and certificates strictly complying with
the terms and conditions of the Letter of Credit. In furtherance and not in
limitation of the foregoing, the Issuing Bank may accept documents that appear
on their face to be in order, without responsibility for further investigation,
regardless of any notice or information to the contrary.

            SECTION 8.12. 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

                                       39
<PAGE>   45
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.

                                       40
<PAGE>   46
            SECTION 8.13. Waiver of Jury Trial. Each of the Borrower, the Agent
and the Lender Parties 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
Letters of Credit or the actions of the Agent or any Lender Party 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.

agree as follows:

            1. The Assignor hereby sells and assigns to the Assignee, and the
Assignee hereby purchases and assumes from the Assignor, an interest in and to

hereof (other than in respect of Competitive Bid Advances and Competitive Bid
Notes) equal to the percentage interest specified on Schedule 1 hereto of all
outstanding rights and obligations under the Credit Agreement (other than in
respect of Competitive Bid Advances and Competitive Bid Notes). After giving
effect to such sale and assignment, the Assignee's Revolving Credit Commitment
and the amount of the Revolving Credit Advances owing to the Assignee will be as
set forth on Schedule 1 hereto.

            2. The Assignor (i) represents and warrants that it is the legal and
beneficial owner of the interest being assigned by it hereunder and that such
interest is free and clear of any adverse claim; (ii) makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with the Credit Agreement
or the execution, legality, validity, enforceability, genuineness, sufficiency
or value of the Credit Agreement or any other instrument or document furnished
pursuant thereto; (iii) 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 the
Credit Agreement or any other instrument or document furnished pursuant thereto;
and (iv) attaches the Revolving Credit Note, if any, held by the Assignor [and
requests that the Agent exchange such Revolving Credit Note for a new Revolving
Credit Note payable to the order of [the Assignee in an amount equal to the
Revolving Credit Commitment assumed by the Assignee pursuant hereto or new
Revolving Credit Notes payable to the order of the Assignee in an amount equal
to the Revolving Credit Commitment assumed by the Assignee pursuant hereto and]
the Assignor in an amount equal to the Revolving Credit Commitment retained by
the Assignor under the Credit Agreement, [respectively,] as specified on
Schedule 1 hereto.

            3. The Assignee (i) confirms that it has received a copy of the
Credit Agreement, together with copies of the financial statements referred to
in Section 4.01 thereof and such other documents and information as it has
deemed appropriate to make its own credit analysis and decision to enter into
this Assignment and Acceptance; (ii) agrees that it will, independently and
without reliance upon the Agent, the Assignor or any other Lender Party 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 the Credit Agreement; (iii) confirms that it is an Eligible Assignee; (iv)
appoints and authorizes the Agent to take such action as agent on its behalf and
to exercise such powers and discretion under the Credit Agreement as are
delegated to the Agent by the terms thereof, together with such powers and
discretion as are reasonably incidental thereto; (v) agrees that it will perform
in accordance with their terms all of the obligations that by the terms of the
Credit Agreement are required to be performed by it as a Lender Party; and (vi)
attaches any U.S. Internal Revenue Service forms required under Section 2.15 of
the Credit Agreement.

            4. Following the execution of this Assignment and Acceptance, it
will be delivered to the Agent for acceptance and recording by the Agent. The
effective date for this Assignment and Acceptance (the "Effective Date") shall
be the date of acceptance hereof by the Agent, unless otherwise specified on
Schedule 1 hereto.
<PAGE>   60
            5. Upon such acceptance and recording by the Agent, as of the
Effective Date, (i) the Assignee shall be a party to the Credit Agreement and,
to the extent provided in this Assignment and Acceptance, have the rights and
obligations of a Lender Party thereunder and (ii) the Assignor shall, to the
extent provided in this Assignment and Acceptance, relinquish its rights and be
released from its obligations under the Credit Agreement.

            6. Upon such acceptance and recording by the Agent, from and after
the Effective Date, the Agent shall make all payments under the Credit Agreement
and the Revolving Credit Notes in respect of the interest assigned hereby
(including, without limitation, all payments of principal, interest and facility
fees with respect thereto) to the Assignee. The Assignor and Assignee shall make
all appropriate adjustments in payments under the Credit Agreement and the
Revolving Credit Notes for periods prior to the Effective Date directly between
themselves.

            7.    This Assignment and Acceptance shall be governed by, and
construed in accordance with, the laws of the State of New York.

            8. This Assignment and Acceptance 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 Schedule 1 to this Assignment and Acceptance by telecopier shall
be effective as delivery of a manually executed counterpart of this Assignment
and Acceptance.

            IN WITNESS WHEREOF, the Assignor and the Assignee have caused
Schedule 1 to this Assignment and Acceptance to be executed by their officers
thereunto duly authorized as of the date specified thereon.

                    AMENDED AND RESTATED EMPLOYMENT AGREEMENT
                          DATED AS OF DECEMBER 19, 1997

          THIS AMENDMENT to the Amended and Restated Employment Agreement, dated
as of December 19, 1997, as amended on December 18, 1998 and April 19, 2000 (as
so amended, the "Employment Agreement"), by and between Gehl Company ("GEHL"), a
Wisconsin corporation with its principal place of business in West Bend,
Wisconsin, and William D. Gehl ("Executive"), is made as of June 13, 2001.

                                    RECITALS

          WHEREAS, GEHL and Executive have previously entered into the
Employment Agreement and wish to enter into this Amendment to amend the
Employment Agreement as provided herein.

          NOW, THEREFORE, in consideration of the mutual promises and agreements
set forth herein, the parties agree as follows:

          Section 2 of the Employment Agreement shall be deleted in its entirety
and replaced with the following:

          Executive's "term of employment," as this phrase is used
          throughout this Agreement, shall be for a period commencing
          on January 1, 1999 and ending on June 13, 2004 unless
          Executive's employment is terminated earlier with the
          consequences described herein in which event the term of
          employment shall extend through the date of such
          termination.

          Section 5 of the Employment Agreement shall be revised by adding the
following new paragraph after subsection (e) and prior to the paragraph
beginning "In addition":

          Executive shall also receive, at the expense of GEHL,
          outplacement services, on an individualized basis at a level
          of service commensurate with Executive's most senior status
          with GEHL during the 180-day period prior to the date of the
          Change in Control, provided by a nationally recognized
          senior executive placement firm selected by GEHL with the
          consent of Executive, provided that the cost to GEHL of such
          services shall not exceed 20% of Executive's Current Base
          Salary. In the alternative, Executive, at his election, may
          choose to receive the net amount of these services, up to a
          maximum of $15,000, to be paid as a lump sum within 30 days
          of the Termination Date as outlined above.
<PAGE>

          Section 5 of the Employment Agreement shall be further revised by
adding the following new subsection (vii) to the definition (the "Definition")
of "Good Reason":

          (vii) Any voluntary termination of employment by Executive
          for any reason where the notice of termination is delivered
          by Executive to GEHL at any time within ninety (90) days
          following the six-month anniversary of the Change in
          Control.

          Section 5 of the Employment Agreement shall be further revised by
deleting the word "or" from the end of subsection (v) to the Definition and by
deleting the period (".") from the end of subsection (vi) to the Definition and
replacing it with a semicolon followed by the word "or" ("; or").

          The following new Section 18 shall be added to the Employment
Agreement:

          Section 18. Expenses and Interest. If (i) a dispute arises
          with respect to the enforcement of Executive's rights under
          this Agreement, (ii) any legal or arbitration proceeding
          shall be brought to enforce or interpret any provision
          contained herein or to recover damages for breach hereof, or
          (iii) any tax audit or proceeding is commenced that is
          attributable in part to the application of Section 4999 of
          the Code, in any case so long as Executive is not acting in
          bad faith, then GEHL shall reimburse Executive for any
          reasonable attorney's fees and necessary costs and
          disbursements incurred as a result of such dispute, legal or
          arbitration proceeding or tax audit or proceeding
          ("Expenses"), and prejudgment interest on any money judgment
          or arbitration award obtained by Executive calculated at the
          rate of interest announced by M&I Bank, Milwaukee,
          Wisconsin, from time to time as its prime or base lending
          rate from the date that payments to Executive should have
          been made under this Agreement. Within ten days after
          Executive's written request therefor, GEHL shall pay to
          Executive, or such person or entity as Executive may
          designate in writing to GEHL, Executive's reasonable
          Expenses in advance of the final disposition or conclusion
          of any such dispute, legal or arbitration proceeding.

          IN WITNESS WHEREOF, GEHL has caused this Amendment to be executed by
its duly authorized officer, and Executive has hereunto set his hand, all as of
the date set forth above.
