Ladies and Gentlemen:

owner of certain shares of Common Stock of the Company ("Common Stock") or

Certain subsidiaries of Fairfax (the "Selling Stockholders") propose to sell

you are relying on the representations and agreements of Fairfax contained in
this letter in carrying out the Transaction.

            In consideration of the foregoing, Fairfax hereby agrees that it

subsidiaries, not to), without your prior written consent, directly or
indirectly, sell, offer, contract or grant any option to sell (including without
limitation any short sale), pledge, transfer, establish an open "put equivalent
position" within the meaning of Rule 16a-1(h) under the Securities Exchange Act
of 1934, as amended, or otherwise dispose of any shares of Common Stock, options
or warrants to acquire shares of Common Stock, or securities exchangeable or
exercisable for or convertible into shares of Common Stock currently or
hereafter owned either of record or beneficially (as defined in Rule 13d-3 under
the Securities Exchange Act of 1934, as amended) by Fairfax (or such entity
under its control), or publicly announce an intention to do any of the
foregoing, for a period commencing on the date hereof and continuing through the
close of trading on the date 30 days after the date hereof.

            Notwithstanding the foregoing, Fairfax may (i) exercise options or
warrants to acquire shares of Common Stock or (ii) transfer the Common Stock (w)
to the Company to pay withholding taxes, or satisfy the exercise price,
applicable to the exercise of options, (x) as a bona fide gift or gifts,
provided that the donee or donees thereof agree to be bound by the restrictions
set forth herein, (y) to any entity under Fairfax's control, including any of
its subsidiaries, provided that such entity agrees to be bound by the
restrictions set forth herein, and provided further that any such transfer shall
not involve a disposition for value or (z) with your prior written consent.

            This agreement is irrevocable and will be binding on Fairfax and the
respective successors, heirs, personal representatives, and assigns of Fairfax.

corresponding amount from such Lender. If such Lender does not pay such
corresponding amount forthwith upon the Agent's demand therefor, the Agent will
promptly notify the Borrower, and the Borrower shall immediately pay such
corresponding amount to the Agent. The Agent shall also be entitled to recover
from the Lender or the Borrower, as the case may be, interest on such
corresponding amount in respect of each day from the date such corresponding
amount was made available by the Agent to the Borrower to the date such
corresponding amount is recovered by the Agent at a per annum rate equal to (i)

a Eurodollar Loan that fails to comply with the terms hereof or any failure to
request an extension of a Eurodollar Loan that fails to comply with the terms
hereof or any failure to request an extension of a Eurodollar Loan at the end of
an Interest Period shall constitute a conversion to a Base Rate Loan on the last
day of the applicable Interest Period. Each continuation or conversion must be
requested by the Borrower no later than noon (Milwaukee time) (i) on the date
for a requested conversion of a Eurodollar Loan to a Base Rate Loan or (ii) two

time after the Revolving Loan Commitment has been terminated or reduced, (iii)
each partial increase shall be made in an aggregate amount at least equal to
$10,000,000 and in integral multiples of $5,000,000 above such amount, (iv) no
more than two such increases shall be made between the Effective Date and the
Maturity Date, and (v) the Borrower shall have delivered to the Agent certified
resolutions of the Board of Directors of the Borrower approving such increase
and borrowings in connection therewith. In the event of such a requested
increase in the Revolving Loan Commitment, (i) each of the Lenders shall be
given the opportunity to participate in the increased Revolving Loan Commitment
(x) initially to the extent of such Lender's existing Commitment Percentage and
(y) to the extent that the requested increase of the Revolving Loan Commitment
is not fulfilled pursuant to the preceding clause (x), ratably in the proportion
that the respective Commitment Percentages of the Lenders desiring to
participate in the requested increase bear to the total of the Commitment
Percentages of the increasing

<PAGE>

 

 Lenders, and (ii) to the extent that the Lenders
do not elect so to participate in such increased Revolving Loan Commitment after
an opportunity to do so, then the Borrower shall consult with the Agent as to
the number, identity and requested Revolving Loan Commitments of additional
financial institutions that the Agent may invite to participate in the aggregate
Revolving Loan Commitment. The Agent will not unreasonably refuse to so invite a
commercial bank organized under the laws of the United States or of any State
thereof, identified and requested by the Borrower, that has capital and surplus
reasonably satisfactory to the Agent in light of the Revolving Loan Commitment
which such commercial bank would assume hereunder. The Agent shall promptly
notify the Borrower and the Lenders of any increase in the amount of the
aggregate Revolving Loan Commitment pursuant to this Section and of the
respective adjusted Revolving Loan Commitment and Commitment Percentage of each
Lender after giving effect thereto. The Borrower acknowledges that, in order to
maintain Loans in accordance with the Commitment Percentage of each Lender, a
non-pro-rata increase in the aggregate Revolving Loan Commitment may require
prepayment or funding of all or portions of certain Loans on the date of such
increase (and any such prepayment or funding shall be subject to the other
provisions of this Credit Agreement).

        2.7 Notes.

        The Revolving Loans made by the Lenders shall be evidenced by
a duly executed promissory note of the Borrower payable to each Lender in
substantially the form of Exhibit 2.7 (the "Revolving Loan Notes")
and in a principal amount equal to the amount of such Lender's Commitment
Percentage of the Revolving Loan Commitment as originally in effect.

        2.8 Swing Line Loans.

        (a) Subject to the terms and conditions set forth herein,
during the period from the Effective Date to the Maturity Date, Swing Line
Lender agrees to make Swing Line Loans to the Borrower as the Borrower may from
time to time request for the purposes permitted hereby; provided, however, that
(i) the aggregate amount of Swing Line Loans outstanding shall not exceed the
Swing Line Sublimit, (ii) Swing Line Lender's pro rata share of the aggregate
amount of Revolving Loans outstanding plus the aggregate amount of Swing Line
Loans outstanding shall not exceed such Lender's Commitment Percentage of the
amount of the Revolving Loan Commitment minus the Letter of Credit Obligations,
and (iii) the sum of all Loans outstanding shall not exceed the amount of the
Revolving Loan Commitment minus the Letter of Credit Obligations. This is a
revolving credit and, subject to the foregoing and the other terms and
conditions hereof, the Borrower may borrow, prepay and reborrow Swing Line Loans
as set forth herein without premium or penalty; provided, however, that Swing
Line Lender may terminate or suspend the Swing Line at any time in its sole
discretion upon notice to the Borrower. Each Swing Line Loan shall bear interest
at a rate equal to the rate applicable to Base Rate Loans or at a rate quoted by
the Agent and agreed to by the Borrower.

        (b) Unless notified to the contrary by Swing Line Lender, the
Borrower may irrevocably request a Swing Line Loan upon notice to Swing Line
Lender. There is no minimum borrowing amount for a Swing Line Loan. Each such
request for a Swing Line Loan shall constitute a representation and warranty by
the Borrower that the conditions set forth in Section 5.2 are satisfied.
Promptly after receipt of such request, Swing Line Lender shall obtain 

 

16

<PAGE>

 

telephonic verification from the Agent that such Swing Line Loan is permitted
hereunder. Upon receiving such verification, Swing Line Lender shall make such
Swing Line Loan available to the Borrower. Without the consent of the Required
Lenders and Swing Line Lender, no Swing Line Loan shall be made during the
continuation of a Default or Event of Default. Upon the making of each Swing
Line Loan, each Lender shall be deemed to have purchased from Swing Line Lender
a risk participation therein in an amount equal to that Lender's Commitment
Percentage times the amount of the Swing Line Loan.

        (c) Each Swing Line Loan shall bear interest at a fluctuating
rate per annum equal to the rate of interest payable on Base Rate Loans or at
the rate quoted by the Agent and agreed to by the Borrower and interest shall be
payable upon demand of Swing Line Lender, on the last day of each month and on
the Revolving Termination Date. Swing Line Lender shall be responsible for
invoicing the Borrower (or notifying the Agent to so invoice the Borrower) for
such interest. The interest payable on Swing Line Loans is solely for the
account of Swing Line Lender, except following any funding of a risk
participation under clause (f) below.

        (d) The Borrower shall repay each Swing Line Loan on the
earliest of (i) upon demand made by Swing Line Lender and (ii) the Revolving
Termination Date. The Borrower shall repay the principal amount of each Swing
Line Loan by payment directly to Swing Line Lender or by Swing Line Lender
debiting the Borrower's deposit account at Swing Line Lender not later than
10:00 a.m. (Milwaukee, Wisconsin time) for payments hereunder. If the conditions
precedent set forth in Section 5.2 can be satisfied, the Borrower may request a
Revolving Loan to repay Swing Line Lender, or, failing to make such request, the
Borrower shall be deemed to have requested a Revolving Loan of Base Rate Loans
on such payment date pursuant to subsection (f) below. Swing Line Lender shall
promptly notify the Agent of each Swing Line Loan and each payment thereof.

        (e) If the Borrower fails to timely make any principal or
interest payment on any Swing Line Loan, Swing Line Lender shall notify the
Agent of such fact and the unpaid amount. The Agent shall promptly notify each
Lender of its pro rata share of such amount by 11:00 a.m. (Milwaukee, Wisconsin
time). Each Lender shall make funds in an amount equal to its pro rata share of
such amount available to the Agent at the Agent's payment office not later than
the 2:00 p.m. (Milwaukee, Wisconsin time) for payments hereunder on the same
Business Day. The obligation of each Lender to make such payment shall be
absolute and unconditional and shall not be affected by the occurrence of an
Event of Default or any other occurrence or event. Any such payment shall not
relieve or otherwise impair the obligation of the Borrower to repay the Swing
Line Lender for any amount of Swing Line Loans, together with interest as
provided herein.

        (f) If the conditions precedent set forth in Section 5.2 can
be satisfied on any date the Borrower is obligated to, but fails to, repay a
Swing Line Loan, the funding by Lenders pursuant to the previous subsection
shall be deemed to be a borrowing of Base Rate Loans (without regard to the
minimum amount therefor) deemed requested by the Borrower. If the conditions
precedent set forth in Section 5.2 cannot be satisfied on the date the Borrower
is obligated to make, but fails to make, such payment, the funding by Lenders
pursuant to the previous subsection shall be deemed to be a funding by each
Lender of its participation in such Swing Line Loan, and each Lender making such
funding shall thereupon acquire a pro rata 

 

17

<PAGE>

 

 participation, to the extent of its
payment, in the claim of Swing Line Lender against the Borrower in respect of
such payment and shall share, in accordance with that pro rata participation, in
any payment made by the Borrower with respect to such claim. Any amounts made
available by a Lender under its risk participation shall be payable by the
Borrower upon demand of the Agent, and shall bear interest at a rate per annum
equal to the Base Rate plus 2% per annum.

        2.9 Letters of Credit.

        (a) Issuance. Subject to the terms and conditions
hereof and of the LOC Documents, if any, and any other terms and conditions
which the Agent may reasonably require, the Agent shall from time to time upon
request issue, and the Lenders shall participate in, letters of credit (the
"Letters of Credit") for the account of the Borrower; provided,
however, that (i) the aggregate amount of Letter of Credit Obligations
shall not at any time exceed $300,000,000 (provided that the foregoing sublimit
shall be increased automatically by the amount of any increase in the aggregate
Revolving Loan Commitment made pursuant to Section 2.6(b), effective as of the
date thereof), (ii) the sum of the aggregate amount of Letter of Credit
Obligations outstanding plus the aggregate amount of Loans outstanding shall not
exceed the Aggregate Commitment and (iii) with respect to each individual
Lender, the Lender's pro rata share of outstanding Loans plus its pro rata share
of outstanding Letter of Credit Obligations shall not exceed such Lender's
Revolving Loan Commitment. The Agent may require the issuance and expiry date of
each Letter of Credit to be a day other than (x) a Saturday or a Sunday or (y)
any other day on which the letter of credit issuing office of the Agent is
authorized or required by law or executive order to close. Each Letter of Credit
shall be a standby or documentary letter of credit issued to support the
obligations (including pension or insurance obligations), contingent or
otherwise, of the Borrower or any of its Subsidiaries. Each Letter of Credit
shall have a stated term not to exceed one year, but may by its terms be
renewable annually upon notice (a "Notice of Renewal") given to
the Agent on or prior to any date for notice of renewal set forth in such Letter
of Credit but in any event at least three Business Days prior to the date of the
proposed renewal of such Letter of Credit and upon fulfillment of the applicable
conditions set forth in Section 5.2 unless the Agent has notified the Borrower
on or prior to the date for notice of termination set forth in such Letter of
Credit but in any event at least 30 Business Days prior to the date of automatic
renewal of its election not to renew such Letter of Credit (a "Notice of
Termination") and (y) 10 Business Days prior to the Maturity Date; provided
that the terms of each Letter of Credit that is automatically renewable annually
shall (x) require the Agent to give the beneficiary named in such Letter of
Credit notice of any Notice of Termination, (y) permit such beneficiary,
upon receipt of such notice, to draw under such Letter of Credit prior to the
date such Letter of Credit otherwise would have been automatically renewed and
(z) not permit the expiration date (after giving effect to any renewal) of
such Letter of Credit in any event to be extended to a date later than 10
Business Days before the Maturity Date. If either a Notice of Renewal is not
given by the Borrower or a Notice of Termination is given by the Agent pursuant
to the immediately preceding sentence, such Letter of Credit shall expire on the
date on which it otherwise would have been automatically renewed; provided,
however, that even in the absence of receipt of a Notice of Renewal the
Agent may in its discretion, unless instructed to the contrary by the Borrower,
deem that a Notice of Renewal had been timely delivered and in such case, a
Notice of Renewal shall be deemed to have been so 

 

18

<PAGE>

 

 delivered for all purposes
under this Agreement. Each Letter of Credit shall comply with the related LOC
Documents.

        (b) Cash Collateral. In the event that any Letter of
Credit remains outstanding beyond the fifteenth day prior to the Maturity Date,
the Borrower shall upon demand of the Required Lenders (or the Agent acting with
the consent of the Required Lenders) either (i) pay to the Agent the sum of the
largest draft which could then or thereafter be drawn under such Letter of
Credit, which sum the Agent may hold for the account of the Borrower, with
interest, for the purpose of paying any draft presented, with the excess, if
any, to be returned to the Borrower upon termination or expiration of such
Letter of Credit or (ii) deliver a back-up letter of credit to the Agent
securing the Borrower's reimbursement obligations with respect to such Letter of
Credit in form and substance acceptable to the Required Lenders and from a
creditworthy financial institution acceptable to the Required Lenders.

        (c) Letter of Credit Fees.

                (1) Letter of Credit Fees. In consideration of
        the issuance of Letters of Credit hereunder, the Borrower agrees to pay
        to the Agent for the pro rata benefit of the Lenders (based on each
        Lender's Commitment Percentage), a per annum fee (the "Letter of
        Credit Fees") equal to the Applicable Percentage on the average
        daily maximum amount available to be drawn under all Letters of Credit.
        The Letter of Credit Fees will be payable in arrears on the first
        Business Day after the end of each fiscal quarter of the Borrower (as
        well as on the Maturity Date) for the immediately preceding fiscal
        quarter (or portion thereof), beginning with the first of such dates to
        occur after the date of this Agreement.

                (2) Agent Letter of Credit Fees. In addition
        to the Letter of Credit Fees payable pursuant to subsection (1) above,
        the Borrower shall pay to the Agent for its own account, without sharing
        by the other Lenders, a fronting fee in an amount agreed by the Borrower
        and the Issuing Bank as a percentage of the outstanding face amount of
        each Letter of Credit payable quarterly in arrears at the same time the
        Letter of Credit Fees are payable plus the customary incidental and/or
        out of pocket charges from time to time for its services in connection
        with the issuance, amendment, payment, transfer, administration,
        cancellation and conversion of, and drawings under, Letters of Credit
        (collectively, the "Agent Letter of Credit Fees").

        (d) Notice and Reports. The request for the issuance
of a Letter of Credit shall be submitted to the Agent at least two Business Days
prior to the requested date of issuance unless otherwise agreed to between the
Borrower and the Agent. The Agent will, at least monthly and more frequently
upon request, provide to the Lenders a detailed report specifying the Letters of
Credit which are then issued and outstanding and any activity with respect
thereto which may have occurred since the date of the prior report, and
including therein, among other things, the account party, the beneficiary, the
face amount, and the expiry date as well as any payments or expirations which
may have occurred.

<PAGE>

 

        (e) Participations. Each Lender, upon issuance of a
Letter of Credit, shall be deemed to have purchased without recourse a risk
participation from the Agent in such Letter of Credit and each LOC Document
related thereto and the rights and obligations arising thereunder and any
collateral relating thereto, in each case in an amount equal to its Commitment
Percentage of the obligations under such Letter of Credit, and shall absolutely,
unconditionally and irrevocably assume, as primary obligor and not as surety,
and be obligated to pay to the Agent therefor and discharge when due, its
Commitment Percentage of the obligations arising under such Letter of Credit.
Without limiting the scope and nature of each Lender's participation in any
Letter of Credit, to the extent that the Agent has not been reimbursed as
required hereunder or under any such Letter of Credit, each such Lender shall
pay to the Agent its Commitment Percentage of such unreimbursed drawing in same
day funds on the day of notification by the Agent of an unreimbursed drawing
pursuant to the provisions of subsection (f) hereof. The obligation of each
Lender to so reimburse the Agent shall be absolute and unconditional and shall
not be affected by the occurrence of a Default, an Event of Default or any other
occurrence or event. Any such reimbursement shall not relieve or otherwise
impair the obligation of the Borrower to reimburse the Agent under any Letter of
Credit, together with interest as hereinafter provided.

        (f) Reimbursement. In the event of any drawing under
any Letter of Credit, the Agent will promptly notify the Borrower. Unless the
Borrower shall immediately notify the Agent of its intent to otherwise reimburse
the Agent, the Borrower shall be deemed to have requested a Revolving Loan at
the Base Rate in the amount of the drawing as provided in subsection (g) hereof,
the proceeds of which will be used to satisfy the reimbursement obligations. The
Borrower shall reimburse the Agent on the day any drawing under any Letter of
Credit is paid either with the proceeds of a Revolving Loan obtained hereunder
or otherwise in same day funds as provided herein or in the LOC Documents. If
the Borrower shall fail to reimburse the Agent as provided hereinabove, the
unreimbursed amount of such drawing shall bear interest at a per annum rate
equal to the Base Rate plus two percent (2%). The Borrower's reimbursement
obligations hereunder shall be absolute and unconditional under all
circumstances (except as expressly set forth below) irrespective of any rights
of set-off, counterclaim or defense to payment the applicable account party or
the Borrower may claim or have against the Agent, the Lenders, the beneficiary
of the Letter of Credit drawn upon or any other Person, including without
limitation, any defense based on any failure of the applicable account party or
the Borrower to receive consideration or the legality, validity, regularity or
unenforceability of the Letter of Credit. The Agent will promptly notify the
Lenders of the amount of any unreimbursed drawing and each Lender shall promptly
pay to the Agent, in immediately available funds, the amount of such Lender's
Commitment Percentage of such unreimbursed drawing. Such payment shall be made
on the day such notice is received by such Lender from the Agent if such notice
is received at or before 2:00 p.m., otherwise such payment shall be made at or
before 12:00 noon on the Business Day next succeeding the day such notice is
received. If such Lender does not pay such amount to the Agent in full upon such
request, such Lender shall, on demand, pay to the Agent interest on the unpaid
amount during the period from the date the Lender received the notice regarding
the unreimbursed drawing until the Lender pays such amount to the Agent in full
at a rate per annum equal to, if paid within two Business Days of the date of
drawing, the Federal Funds Rate and thereafter at a rate equal to the Base Rate.
Each Lender's obligation to make such payment to the Agent, and the right of the
Agent to receive the same, shall be absolute and unconditional, shall not be
affected by any circumstance whatsoever and 

 

20

<PAGE>

 

 without regard to the termination of
this Credit Agreement or the Revolving Loan Commitments hereunder, the existence
of a Default or Event of Default or the acceleration of the obligations
hereunder and shall be made without any offset, abatement, withholding or
reduction whatsoever. Simultaneously with the making of each such payment by a
Lender to the Agent, such Lender shall, automatically and without any further
action on the part of the Agent or such Lender, acquire a participation in an
amount equal to such payment (excluding the portion of such payment constituting
interest owing to the Agent) in the related unreimbursed drawing portion of the
Letter of Credit Obligation and in the interest thereon and in the related LOC
Documents, and shall have a claim against the Borrower with respect thereto.

        (g) Repayment with Revolving Loans. On any day on
which the Borrower shall have requested, or been deemed to have requested, a
Revolving Loan to reimburse a drawing under a Letter of Credit, the Agent shall
give notice to the Lenders that a Revolving Loan has been requested or deemed
requested in connection with a drawing under a Letter of Credit, in which case a
Revolving Loan comprised solely of Base Rate Loans (each such borrowing, a
"Mandatory Borrowing") shall be immediately made from all
Lenders (without giving effect to any termination of the Revolving Loan
Commitments pursuant to Section 9.1) pro rata based on each Lender's respective
Commitment Percentage and the proceeds thereof shall be paid directly to the
Agent for application to the respective Letter of Credit Obligations. Each
Lender hereby irrevocably agrees to make such Revolving Loans upon any such
request or deemed request on account of each such Mandatory Borrowing in the
amount and in the manner specified in the preceding sentence and on the same
such date notwithstanding (i) the amount of Mandatory Borrowing may not
comply with the minimum amount for borrowings of Revolving Loans otherwise
required hereunder, (ii) whether any conditions specified in Article III are
then satisfied, (iii) whether a Default or Event of Default then exists, (iv)
failure of any such request or deemed request for Revolving Loans to be made by
the time otherwise required hereunder, (v) the date of such Mandatory Borrowing,
or (vi) any reduction in or any termination of the Revolving Loan Commitments.
Such funding of Revolving Loans shall be made on the day notice of such
Mandatory Borrowing is received by each Lender from the Agent if such notice is
received at or before 2:00 p.m., otherwise such payment shall be made at or
before 12:00 noon on the Business Day next succeeding the day such notice is
received. In the event that any Mandatory Borrowing cannot for any reason be
made on the date otherwise required above (including, without limitation, as a
result of the commencement of a proceeding under any applicable bankruptcy law
with respect to the Borrower), then each Lender hereby agrees that it shall
forthwith fund (as of the date the Mandatory Borrowing would otherwise have
occurred, but adjusted for any payments received from the Borrower on or after
such date and prior to such purchase) its Commitment Percentage in the
outstanding Letter of Credit Obligations; provided, further, that
in the event any Lender shall fail to fund its Commitment Percentage on the day
the Mandatory Borrowing would otherwise have occurred, then the amount of such
Lender's unfunded Commitment Percentage therein shall bear interest payable to
the Agent upon demand, at the rate equal to, if paid within two Business Days of
such date, the Federal Funds Rate, and thereafter at a rate equal to the Base
Rate.

        (h) Modification and Extension. The issuance of any
supplement, modification, amendment, or extension to any Letter of Credit shall,
for purposes hereof, be treated in all respects the same as the issuance of a
new Letter of Credit.

 

21

<PAGE>

 

        (i) International Standby Practices. The Agent may
have the Letters of Credit be subject to International Standby Practices, as
published as of the date of issue by the International Chamber of Commerce
(Publication No. 590 or the most recent publication, the "ISP 98"),
in which case the ISP 98 may be incorporated therein and deemed in all respects
to be a part thereof.

        (j) Responsibility of Agent. It is expressly
understood and agreed as between the Lenders that the obligations of the Agent
hereunder to the Lenders are only those expressly set forth in this Credit
Agreement and that the Agent shall be entitled to assume that the conditions
precedent set forth in Section 5 have been satisfied unless it shall have
acquired actual knowledge that any such condition precedent has not been
satisfied; provided, however, that nothing set forth in this Section 2.9 shall
be deemed to prejudice the right of any Lender to recover from the Agent any
amounts made available by such Lender to the Agent pursuant to this Section 2.9
in the event that it is determined by a court of competent jurisdiction that the
issuance of or payment with respect to a Letter of Credit constituted gross
negligence or willful misconduct on the part of the Agent.

        (k) Conflict with LOC Documents. In the event of any
conflict between this Credit Agreement and any LOC Document, this Credit
Agreement shall govern.

        (l) Indemnification of Agent.

                (1) In addition to its other obligations under this
        Credit Agreement, the Borrower hereby agrees to protect, indemnify, pay
        and save the Agent harmless from and against any and all claims,
        demands, liabilities, damages, losses, costs, charges and expenses
        (including reasonable, documented attorneys' fees) that the Agent may
        incur or be subject to as a consequence, direct or indirect, of (A) the
        issuance of any Letter of Credit or (B) the failure of the Agent to
        honor a drawing under a Letter of Credit as a result of any act or
        omission, whether rightful or wrongful, of any present or future de jure
        or de facto government or governmental authority (all such acts or
        omissions, herein called "Government Acts").

                (2) As between the Borrower and the Agent and the
        Lenders, the Borrower shall assume all risks of the acts, omissions or
        misuse of any Letter of Credit by the beneficiary thereof. The Agent and
        the Lenders shall not be responsible for (except in the case of (A), (B)
        and (C) below if the Agent has actual knowledge to the contrary): (A)
        the form, validity, sufficiency, accuracy, genuineness or legal effect
        of any document submitted by any party in connection with the
        application for and issuance of any Letter of Credit, even if it should
        in fact prove to be in any or all respects invalid, insufficient,
        inaccurate, fraudulent or forged; provided that such document(s)
        reasonably appear to conform on their face to the terms of the Letter of
        Credit, (B) the validity or sufficiency of any instrument transferring
        or assigning or purporting to transfer or assign any Letter of Credit or
        the rights or benefits thereunder or proceeds thereof, in whole or in
        part, that may prove to be invalid or ineffective for any reason; (C)
        failure of the beneficiary of a Letter of Credit to comply fully with
        conditions required in order 

 

22

<PAGE>

 

         to draw upon a Letter of Credit; provided
        that such document(s) reasonably appear to conform on their face to the
        terms of the Letter of Credit, (D) errors, omissions, interruptions or
        delays in transmission or delivery of any messages, by mail, cable,
        telegraph, telex or otherwise, whether or not they be in cipher; (E)
        errors in interpretation of technical terms; (F) any loss or delay in
        the transmission or otherwise of any document required in order to make
        a drawing under a Letter of Credit or of the proceeds thereof; and (G)
        any consequences arising from causes beyond the control of the Agent,
        including, without limitation, any Government Acts. None of the above
        shall affect, impair, or prevent the vesting of the Agent's rights or
        powers hereunder.

                (3) In furtherance and extension and not in
        limitation of the specific provisions hereinabove set forth, any action
        taken or omitted by the Agent, under or in connection with any Letter of
        Credit or the related certificates, if taken or omitted in good faith
        and not deemed to constitute gross negligence or willful misconduct,
        shall not put the Agent under any resulting liability to the Borrower.
        It is the intention of the parties that this Credit Agreement shall be
        construed and applied to protect and indemnify the Agent against any and
        all risks involved in the issuance of the Letters of Credit, all of
        which risks are hereby assumed by the Borrower, including, without
        limitation, any and all risks of the acts or omissions, whether rightful
        or wrongful, of any present or future Government Acts. The Agent shall
        not, in any way, be liable for any failure by the Agent or anyone else
        to pay any drawing under any Letter of credit as a result of any
        Government Acts or any other cause beyond the control of the Agent.

                (4) Nothing in this subsection (l) is intended to
        limit the reimbursement obligation of the Borrower contained in this
        Section 2.9. The obligations of the Borrower under this subsection (l)
        shall survive the termination of this Credit Agreement. No act or
        omission of any current or prior beneficiary of a Letter of Credit shall
        in any way affect or impair the rights of the Agent to enforce any
        right, power or benefit under this Credit Agreement.

                (5) Notwithstanding anything to the contrary
        contained in this subsection (l) or in any LOC Document, neither the
        Borrower nor any Lender shall have any obligation to indemnify the Agent
        in respect of any liability incurred by the Agent arising out of the
        gross negligence or willful misconduct of the Agent, as determined by a
        court of competent jurisdiction. Nothing in this Credit Agreement shall
        relieve the Agent of any liability to the Borrower or any Lender in
        respect of any action taken by the Agent which action constitutes gross
        negligence or willful misconduct of the Agent or a violation of the UCP
        or Uniform Commercial Code (as applicable), as determined by a court of
        competent jurisdiction.

        (m) Letters of Credit Under the 2004 Credit Agreement.
Upon the Effective Date, all letters of credit issued or deemed issued by U.S.
Bank National Association under the 2004 Credit Agreement shall automatically be
deemed Letters of Credit issued by the Agent under this Agreement subject to all
of the terms and conditions hereof including, among other things, that 

 

23

<PAGE>

 

 the
Lenders will automatically be deemed to have purchased a participation in such
letters of credit as of the Effective Date and the Borrower shall have the
reimbursement obligations with respect thereto set forth in Section 2.9(f)
above.

    Section 3. PAYMENTS

        3.1 Interest.

        (a) Interest Rate.

                (i) All Base Rate Loans shall accrue interest at the
        Base Rate.

                (ii) All Eurodollar Loans shall accrue interest at
        the Adjusted Eurodollar Rate applicable to such Eurodollar Loan.

        (b) Default Rate of Interest. Upon the occurrence, and
during the continuance, of an Event of Default, the principal of and, to the
extent permitted by law, interest on the Loans and any other amounts owing
hereunder or under the other Credit Documents shall bear interest, payable on
demand, at a per annum rate equal to two percent (2%) plus the rate which would
otherwise be applicable (or if no rate is applicable, then the rate for
Revolving Loans that are Base Rate Loans plus two percent (2%) per annum).

        (c) Interest Payments. Interest on Loans shall be due
and payable in arrears on each Interest Payment Date.

        3.2 Prepayments.

        (a) Voluntary Prepayments. The Borrower shall have the
right to prepay Loans in whole or in part from time to time without premium or
penalty; provided, however, that (i) Eurodollar Loans may only be
prepaid on three Business Days' prior written notice to the Agent and any
prepayment of Eurodollar Loans will be subject to Section 4.3; and (ii) each
such partial prepayment of Loans shall be in the minimum principal amount of
$1,000,000; provided that if less than $1,000,000 would remain
outstanding after such prepayment, such prepayment shall be in the amount of the
entire outstanding principal amount of the Loans. Amounts prepaid hereunder
shall be applied as the Borrower may elect; provided that if the Borrower
fails to specify a voluntary prepayment then such prepayment shall be applied as
the Agent may direct. All voluntary prepayments shall be applied first to Swing
Line Loans, then to Revolving Loans that are Base Rate Loans, and then to
Revolving Loans that are Eurodollar Loans in direct order of Interest Period
maturities.

        (b) Mandatory Prepayments. If at any time the amount
of Loans outstanding plus the Letter of Credit Obligations outstanding exceeds
the Aggregate Commitment, the Borrower shall immediately make a principal
payment to the Agent in the manner and in an amount such that the sum of Loans
outstanding plus the Letter of Credit Obligations outstanding is less than or
equal to the Aggregate Commitment. Any payments made under this Section 3.2(b)
shall be subject to Section 4.3 and shall be applied first to Swing Line Loans,
then to Revolving Loans that are Base Rate Loans, and then to Revolving Loans
that are Eurodollar Loans in direct order of Interest Period maturities.

        3.3 Payment in Full at Maturity.

        On the Maturity Date, the entire outstanding principal
balance of all Loans and the Letter of Credit Obligations (to the extent that
the Borrower has not provided cash collateral or provided a back-up letter of
credit pursuant to Section 2.9(b) above), together with accrued but unpaid
interest and all other sums owing under this Credit Agreement, shall be due and
payable in full, unless accelerated sooner pursuant to Section 9.2.

        3.4 Fees.

        (a) Revolving Fees. In consideration of the Revolving
Loan Commitment being made available by the Lenders hereunder, the Borrower
agrees to pay to the Agent, for the pro rata benefit of each Lender, a fee equal
to the Applicable Percentage for Revolving Fees multiplied by the Revolving Loan
Commitment (the "Revolving Fees"). The accrued Revolving Fees
shall be due and payable in arrears on the first Business Day after the end of
each fiscal quarter of the Borrower (as well as on the Maturity Date and on any
date that the Revolving Loan Commitment is reduced) for the immediately
preceding fiscal quarter (or portion thereof), beginning with the first of such
dates to occur after the Closing Date.

        (b) Utilization Fees. At any time the principal amount
of outstanding Loans and outstanding Letter of Credit Obligations hereunder
shall exceed an amount equal to fifty percent (50%) of the Aggregate
Commitment, the Borrower shall pay to the Agent hereunder, for the pro rata
benefit of the Lenders, fees ("Utilization Fees") equal
to .10% per annum on the principal amount of outstanding Loans and Letter
of Credit Obligations. The Utilization Fees, if any, shall be due and payable in
arrears on the first Business Day after the end of each fiscal quarter of the
Borrower (as well as the Maturity Date) and any date of reduction in the
Revolving Loan Commitments.

        (c) Administrative Fees. The Borrower agrees to pay to
the Agent, for its own account, an annual fee as agreed to between the Borrower
and the Agent in the Fee Letter.

        3.5 Place and Manner of Payments.

        All payments of principal, interest, fees, expenses and other
amounts to be made by the Borrower under this Credit Agreement shall be received
without setoff, deduction or counterclaim not later than 2:00 p.m.(Milwaukee
time) on the date when due in Dollars and in immediately available funds by the
Agent at its offices in Milwaukee, Wisconsin. The Agent may charge account no.
121641146 of the Borrower for principal, interest and fees due hereunder and
under the Notes. Unless the application of a payment is specifically directed by
the Borrower (or if such application would be inconsistent with the terms
hereof), the Agent shall distribute payments received from the Borrower to the
Lenders in such manner as it reasonably determines in its sole discretion.

        3.6 Pro Rata Treatment.

        Except to the extent otherwise provided herein, all Revolving
Loans, each payment or prepayment of principal of any Revolving Loan, each
payment of interest on the Revolving Loans, each payment of Revolving Fees, each
reduction of the Revolving Loan 

 

25

<PAGE>

 

 Commitment, and each conversion or continuation
of any Revolving Loans, shall be allocated pro rata among the Lenders in
accordance with the respective Commitment Percentages; provided that, if any
Lender shall have failed to pay its applicable pro rata share of any Revolving
Loan, then any amount to which such Lender would otherwise be entitled pursuant
to this Section 3.6 shall instead be payable to the Agent until the share of
such Revolving Loan not funded by such Lender has been repaid; and provided,
further, that in the event any amount paid to any Lender pursuant to this
Section 3.6 is rescinded or must otherwise be returned by the Agent, each Lender
shall, upon the request of the Agent, repay to the Agent the amount so paid to
such Lender, with interest for the period commencing on the date such payment is
returned by the Agent until the date the Agent receives such repayment at a rate
per annum equal to, during the period to but excluding the date two Business
Days after such request, the Federal Funds Rate, and thereafter, the Base Rate
plus two percent (2%) per annum.

        3.7 Computations of Interest and Fees.

        (a) Except for Base Rate Loans, on which interest shall be
computed on the basis of a 365 or 366 day year as the case may be, all
computations of interest and fees hereunder shall be made on the basis of the
actual number of days elapsed over a year of 360 days.

        (b) It is the intent of the Lenders and the Borrower to
conform to and contract in strict compliance with applicable usury law from time
to time in effect. All agreements between the Lenders and the Borrower are
hereby limited by the provisions of this paragraph which shall override and
control all such agreements, whether now existing or hereafter arising and
whether written or oral. In no way, nor in any event or contingency (including
but not limited to prepayment or acceleration of the maturity of any
obligation), shall the interest taken, reserved, contracted for, charged, or
received under this Credit Agreement, under the Notes or otherwise, exceed the
maximum nonusurious amount permissible under applicable law. If, from any
possible construction of any of the Credit Documents or any other document,
interest would otherwise be payable in excess of the maximum nonusurious amount,
any such construction shall be subject to the provisions of this paragraph and
such documents shall be automatically reduced to the maximum nonusurious amount
permitted under applicable law, without the necessity of execution of any
amendment or new document. If any Lender shall ever receive anything of value
which is characterized as interest on the Loans under applicable law and which
would, apart from this provision, be in excess of the maximum lawful amount, an
amount equal to the amount which would have been excessive interest shall,
without penalty, be applied to the reduction of the principal amount owing on
the Loans and not to the payment of interest, or refunded to the Borrower or the
other payor thereof if and to the extent such amount which would have been
excessive exceeds such unpaid principal amount of the Loans. The right to demand
payment of the Loans or any other indebtedness evidenced by any of the Credit
Documents does not include the right to receive any interest which has not
otherwise accrued on the date of such demand, and the Lenders do not intend to
charge or receive any unearned interest in the event of such demand. All
interest paid or agreed to be paid to the Lenders with respect to the Loans
shall, to the extent permitted by applicable law, be amortized, prorated,
allocated, and spread throughout the full stated term (including any renewal or
extension) of the Loans so that the amount of interest on account of such
indebtedness does not exceed the maximum nonusurious amount permitted by
applicable law.

        3.8 Sharing of Payments.

        Each Lender agrees that, in the event that any Lender shall
obtain payment in respect of any Loan or any other obligation owing to such
Lender under this Credit Agreement through the exercise of a right of set-off,
banker's lien, counterclaim or otherwise (including, but not limited to,
pursuant to the Bankruptcy Code) in excess of its pro rata share as provided for
in this Credit Agreement, such Lender shall promptly purchase from the other
Lenders a participation in such Loans and other obligations, in such amounts and
with such other adjustments from time to time, as shall be equitable in order
that all Lenders share such payment in accordance with their respective ratable
shares as provided for in this Credit Agreement. Each Lender further agrees that
if a payment to a Lender (which is obtained by such Lender through the exercise
of a right of set-off, banker's lien, counterclaim or otherwise) shall be
rescinded or must otherwise be restored, each Lender which shall have shared the
benefit of such payment shall, by repurchase of a participation theretofore
sold, return its share of that benefit to each Lender whose payment shall have
been rescinded or otherwise restored. The Borrower agrees that any Lender so
purchasing such a participation may, to the fullest extent permitted by law,
exercise all rights of payment, including set-off, banker's lien or
counterclaim, with respect to such participation as fully as if such Lender were
a holder of such Loan or other obligation in the amount of such participation.
Except as otherwise expressly provided in this Credit Agreement, if any Lender
shall fail to remit to the Agent or any other Lender an amount payable by such
Lender to the Agent or such other Lender pursuant to this Credit Agreement on
the date when such amount is due, such payments shall accrue interest thereon,
for each day from the date such amount is due until the day such amount is paid
to the Agent or such other Lender, at a rate per annum equal to the Federal
Funds Rate. If under any applicable bankruptcy, insolvency or other similar law,
any Lender receives a secured claim in lieu of a setoff to which this Section
3.8 applies, such Lender shall, to the extent practicable, exercise its rights
in respect of such secured claim in a manner consistent with the rights of the
Lenders under this Section 3.8 to share in the benefits of any recovery on such
secured claim.

        3.9 Evidence of Debt.

        (a) Each Lender shall maintain an account or accounts
evidencing each Loan made by such Lender to the Borrower from time to time,
including the amounts of principal and interest payable and paid to such Lender
from time to time under this Credit Agreement. Each Lender will make reasonable
efforts to maintain the accuracy of its account or accounts and to promptly
update its account or accounts from time to time, as necessary.

        (b) The Agent shall maintain the Register pursuant to Section
11.3(c), and a subaccount for each Lender, in which Register and subaccounts
(taken together) shall be recorded (i) the amount, type and Interest Period of
each such Loan hereunder, (ii) the amount of any principal or interest due and
payable or to become due and payable to each Lender hereunder and (iii) the
amount of any sum received by the Agent hereunder from or for the account of the
Borrower and each Lender's share thereof. The Agent will make reasonable efforts
to maintain the accuracy of the subaccounts referred to in the preceding
sentence and to promptly update such subaccounts from time to time, as
necessary.

 

27

<PAGE>

 

        (c) The entries made in the accounts, Register and
subaccounts maintained pursuant to subsection (b) of this Section 3.9 (and, if
consistent with the entries of the Agent, subsection (a)) shall be prima facie
evidence of the existence and amounts of the obligations of the Borrower therein
recorded; provided, however, that the failure of any Lender or the
Agent to maintain any such account, such Register or such subaccount, as
applicable, or any error therein, shall not in any manner affect the obligation
of the Borrower to repay the Loans made by such Lender in accordance with the
terms hereof.

    Section 4. ADDITIONAL PROVISIONS REGARDING LOANS

        4.1 Eurodollar Loan Provisions.

        (a) Unavailability. In the event that the Agent shall
have determined in good faith (i) that U.S. dollar deposits in the principal
amounts requested with respect to a Eurodollar Loan are not generally available
in the London interbank Eurodollar market or (ii) that reasonable means do not
exist for ascertaining the Eurodollar Rate, the Agent shall, as soon as
practicable thereafter, give notice of such determination to the Borrower and
the Lenders. In the event of any such determination under clauses (i) or (ii)
above, until the Agent shall have advised the Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, (A) any request by the
Borrower for Eurodollar Loans shall be deemed to be a request for Base Rate
Loans, (B) any request by the Borrower for conversion into or continuation of
Eurodollar Loans shall be deemed to be a request for conversion into or
continuation of Base Rate Loans and (C) any Loans that were to be converted or
continued as Eurodollar Loans on the first day of an Interest Period shall be
converted to or continued as Base Rate Loans.

        (b) Change in Legality. Notwithstanding any other
provision herein, if any change, after the date hereof, in any law or regulation
(including the introduction of any new law or regulation) or in the
interpretation thereof by any Governmental Authority charged with the
administration or interpretation thereof shall make it unlawful for any Lender
to make or maintain any Eurodollar Loan or to give effect to its obligations as
contemplated hereby with respect to any Eurodollar Loan, then, by written notice
to the Borrower and to the Agent, such Lender may:

            (A) declare that Eurodollar Loans, and conversions to or
    continuations of Eurodollar Loans, will not thereafter be made by such
    Lender hereunder, whereupon any request by the Borrower for, or for
    conversion into or continuation of, Eurodollar Loans shall, as to such
    Lender only, be deemed a request for, or for conversion into or continuation
    of, Base Rate Loans, unless such declaration shall be subsequently
    withdrawn; and

            (B) require that all outstanding Eurodollar Loans made by
    it be converted to Base Rate Loans in which event all such Eurodollar Loans
    shall be automatically converted to Base Rate Loans.

        In the event any Lender shall exercise its rights under
clause (A) or (B) above, all payments and prepayments of principal which would
otherwise have been applied to repay the Eurodollar Loans that would have been
made by such Lender or the converted Eurodollar Loans 

 

28

<PAGE>

 

 of such Lender shall
instead be applied to repay the Base Rate Loans made by such Lenders in lieu of,
or resulting from the conversion of, such Eurodollar Loans.

        (c) Requirements of Law. If at any time a Lender shall
incur increased costs or reductions in the amounts received or receivable
hereunder with respect to the making, the commitment to make or the maintaining
of any Eurodollar Loan because of (i) any change, after the date hereof, in any
applicable law, governmental rule, regulation, guideline or order (or in the
interpretation or administration thereof and including the introduction of any
new law or governmental rule, regulation, guideline or such order) including,
without limitation, the imposition, modification or deemed applicability of any
reserves, deposits or similar requirements (such as, for example, but not
limited to, a change in official reserve requirements, but, in all events,
excluding reserves required under Regulation D to the extent included in the
computation of the Adjusted Eurodollar Rate) or (ii) other circumstances
affecting the London interbank Eurodollar market; then the Borrower shall pay to
such Lender promptly upon written demand therefore, accompanied by a statement
in reasonable detail showing the calculation of the amount demanded, such
additional amounts (in the form of an increased rate of, or a different method
of calculating, interest or otherwise as such Lender may determine in its
reasonable discretion) as may be required to compensate such Lender for such
increased costs or reductions in amounts receivable hereunder. Each
determination and calculation made by a Lender under this Section 4.1 shall,
absent manifest error, be binding and conclusive on the parties hereto. Any
conversions of Eurodollar Loans made pursuant to this Section 4.1 shall subject
the Borrower to the payments required by Section 4.3. This Section shall survive
termination of this Credit Agreement and the other Credit Documents and payment
of the Loans and all other amounts payable hereunder.

        Failure or delay on the part of any Lender to demand
compensation pursuant to this Section 4.1 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 90 days prior to the date that
such Lender notifies the Borrower of the change in or in the interpretation of
law or regulation giving rise to such increased costs or reductions and of such
Lender's intention to claim compensation therefor; provided further
that, if the change in or in the interpretation of law or regulation giving rise
to such increased costs or reductions is retroactive, then the 90-day period
referred to above shall be extended to include the period of retroactive effect
thereof.

        4.2 Capital Adequacy.

        If any Lender has determined that the adoption or
effectiveness, after the date hereof, of any applicable law, rule or regulation
regarding capital adequacy, or any change therein (after the date hereof), or
any change in the interpretation or administration thereof by any Governmental
Authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by such Lender (or its parent corporation)
with any request or directive regarding capital adequacy (whether or not having
the force of law) of any such authority, central bank or comparable agency, has
or would have the effect of reducing the rate of return on such Lender's (or
parent corporation's) capital or assets as a consequence of its commitments or
obligations hereunder to a level below that which such Lender (or its parent
corporation) could have achieved but for such adoption, effectiveness, change or
compliance 

 

29

<PAGE>

 

 (taking into consideration such Lender's (or parent corporation's)
policies with respect to capital adequacy), then, upon notice from such Lender,
accompanied by a statement in reasonable detail showing the calculation of the
amount demanded, the Borrower shall pay to such Lender such additional amount or
amounts as will compensate such Lender for such reduction. Each determination by
any such Lender of amounts owing under this Section 4.2 shall, absent manifest
error, be conclusive and binding on the parties hereto. This Section shall
survive termination of this Credit Agreement and the other Credit Documents and
payment of the Loans and all other amounts payable hereunder.

        Failure or delay on the part of any Lender to demand
compensation pursuant to this Section 4.2 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 90 days prior to the date that
such Lender notifies the Borrower of the change in or in the interpretation of
law or regulation giving rise to such increased costs or reductions and of such
Lender's intention to claim compensation therefor; provided further
that, if the change in or in the interpretation of law or regulation giving rise
to such increased costs or reductions is retroactive, then the 90-day period
referred to above shall be extended to include the period of retroactive effect
thereof.

        4.3 Compensation.

        The Borrower promises to indemnify each Lender and to hold
each Lender harmless from any loss or expense which such Lender may sustain or
incur as a consequence of (a) default by the Borrower in making a borrowing of,
conversion into or continuation of Eurodollar Loans after the Borrower has given
a notice requesting the same in accordance with the provisions of this Credit
Agreement, (b) default by the Borrower in making any prepayment of a Eurodollar
Loan after the Borrower has given a notice thereof in accordance with the
provisions of this Credit Agreement, (c) the making of a prepayment of
Eurodollar Loans on a day which is not the last day of an Interest Period with
respect thereto and (d) the payment, continuation or conversion of a Eurodollar
Loan on a day which is not the last day of the Interest Period applicable
thereto or the failure to repay a Eurodollar Loan when required by the terms of
this Credit Agreement. Such indemnification may include an amount equal to (i)
an amount of interest calculated at the Eurodollar Rate which would have accrued
on the amount in question, for the period from the date of such prepayment or of
such failure to borrow, convert, continue or repay to the last day of the
applicable Interest Period (or, in the case of a failure to borrow, convert or
continue, the Interest Period that would have commenced on the date of such
failure) in each case at the applicable rate of interest for such Eurodollar
Loans provided for herein minus (ii) the amount of interest (as reasonably
determined by such Lender) which would have accrued to such Lender on such
amount by placing such amount on deposit for a comparable period with leading
banks in the interbank Eurocurrency market. The agreements in this Section shall
survive the termination of this Credit Agreement and the payment of the Loans
and all other amounts payable hereunder.

        4.4 Taxes.

        (a) Except as provided below in this Section 4.4, all
payments made by the Borrower under this Credit Agreement and any Notes shall be
made free and clear of, and 

 

30

<PAGE>

 

 without deduction or withholding for or on account
of, any present or future income, stamp or other taxes, levies, imposts, duties,
charges, fees, deductions or withholdings, now or hereafter imposed, levied,
collected, withheld or assessed by any court, or governmental body, agency or
other official, excluding taxes measured by or imposed upon the net income of
any Lender or its applicable lending office, or any branch or affiliate thereof,
and all franchise taxes, branch taxes, taxes on doing business or taxes on the
capital or net worth of any Lender or its applicable lending office, or any
branch or affiliate thereof, in each case imposed in lieu of net income taxes: (i)
by the jurisdiction under the laws of which such Lender, applicable lending
office, branch or affiliate is organized or is located, or in which its
principal executive office is located, or any nation within which such
jurisdiction is located or any political subdivision thereof or (ii) by reason
of any connection between the jurisdiction imposing such tax and such Lender,
applicable lending office, branch or affiliate other than a connection arising
solely from such Lender having executed, delivered or performed its obligations,
or received payment under or enforced, this Credit Agreement or any Notes. If
any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions
or withholdings ("Non-Excluded Taxes") are required to be
withheld from any amounts payable to an Agent or any Lender hereunder or under
any Notes, (A) the amounts so payable to the Agent or such Lender shall be
increased to the extent necessary to yield to the Agent or such Lender (after
payment of all Non-Excluded Taxes) interest or any such other amounts payable
hereunder at the rates or in the amounts specified in this Credit Agreement and
any Notes, provided, however, that the Borrower shall be entitled
to deduct and withhold any Non-Excluded Taxes and shall not be required to
increase any such amounts payable to any Lender that is not organized under the
laws of the United States of America or a state thereof if such Lender fails to
comply with the requirements of paragraph (b) of this Section 4.4 whenever any
Non-Excluded Taxes are payable by the Borrower, and (B) as promptly as possible
after requested, the Borrower shall send to the Agent for its own account or for
the account of such Lender, as the case may be, a certified copy of an original
official receipt received by the Borrower showing payment thereof. If the
Borrower fails to pay any Non-Excluded Taxes of which it has notice when due to
the appropriate taxing authority or fails to remit to the Agent the required
receipts or other required documentary evidence, the Borrower shall indemnify
the Agent and any Lender for any incremental Non Excluded Taxes, interest or
penalties that may become payable by the Agent or any Lender as a result of any
such failure. The agreements in this Section 4.4 shall survive the termination
of this Credit Agreement and the payment of the Loans and all other amounts
payable hereunder.

        (b) Each Lender that is not incorporated under the laws of
the United States of America or a state thereof shall:

  
    (A) on or before the date of any payment by the Borrower
    under this Credit Agreement or the Notes to such Lender, deliver to the
    Borrower and the Agent (x) two duly completed copies of United States
    Internal Revenue Service Form W-8ECI or W-8BEN, or successor applicable
    form, as the case may be, certifying that it is entitled to receive payments
    under this Credit Agreement and any Notes without deduction or withholding
    of any United States federal income taxes and (y) an Internal Revenue
    Service Form W-8 or W-9, or successor applicable form, as the case may be,
    certifying that it is entitled to an exemption from United States backup
    withholding tax;

  

 

31

<PAGE>

 

     

  
    (B) deliver to the Borrower and the Agent two further
    copies of any such form or certification on or before the date that any such
    form or certification expires or becomes obsolete and after the occurrence
    of any event requiring a change in the most recent form previously delivered
    by it to the Borrower; and

    (C) obtain such extensions of time for filing and
    complete such forms or certifications as may reasonably be requested by the
    Borrower or the Agent; or

    
        (ii) in the case of any such Lender that is not a
        "bank" within the meaning of Section 881(c)(3)(A) of the
        Internal Revenue Code, (A) represent to the Borrower (for the benefit of
        the Borrower and the Agent) that it is not a bank within the meaning of
        Section 88l(c)(3)(A) of the Internal Revenue Code, (B) agree to furnish
        to the Borrower, on or before the date of any payment by the Borrower,
        with a copy to the Agent, two accurate and complete original signed
        copies of Internal Revenue Service Form W-8, or successor applicable
        form certifying to such Lender's legal entitlement at the date of such
        certificate to an exemption from U.S. withholding tax under the
        provisions of Section 881(c) of the Internal Revenue Code with respect
        to payments to be made under this Credit Agreement and any Notes (and to
        deliver to the Borrower and the Agent two further copies of such form on
        or before the date it expires or becomes obsolete and after the
        occurrence of any event requiring a change in the most recently provided
        form and, if necessary, obtain any extensions of time reasonably
        requested by the Borrower or the Agent for filing and completing such
        forms), and (C) agree, to the extent legally entitled to do so, upon
        reasonable request by the Borrower, to provide to the Borrower (for the
        benefit of the Borrower and the Agent) such other forms as may be
        reasonably required in order to establish the legal entitlement of such
        Lender to an exemption from withholding with respect to payments under
        this Credit Agreement and any Notes.

    

  

        Notwithstanding the above, if any change in treaty, law or
regulation has occurred after the date such Person becomes a Lender hereunder
which renders all such forms inapplicable or which would prevent such Lender
from duly completing and delivering any such form with respect to it and such
Lender so advises the Borrower and the Agent, then such Lender shall be exempt
from such requirements. Each Person that shall become a Lender or a participant
of a Lender pursuant to Section 11.3 shall, upon the effectiveness of the
related transfer, be required to provide all of the forms, certifications and
statements required pursuant to this subsection (b); provided that in the case
of a participant of a Lender, the obligations of such participant of a Lender
pursuant to this subsection (b) shall be determined as if the participant of a
Lender were a Lender except that such participant of a Lender shall furnish all
such required forms, certifications and statements to the Lender from which the
related participation shall have been purchased.

        4.5 Replacement of Lenders.

        The Agent and each Lender shall use reasonable efforts to
avoid or mitigate any increased cost or suspension of the availability of an
interest rate under Sections 4.1 through 4.4 above to the greatest extent
practicable (including transferring the Loans to another lending 

 

32

<PAGE>

 

 office of
Affiliate of a Lender) unless, in the opinion of the Agent or such Lender, such
efforts would be likely to have an adverse effect upon it. In the event a Lender
makes a request to the Borrower for additional payments in accordance with
Section 4.1, 4.2 or 4.4, then, provided that no Default or Event of Default has
occurred and is continuing at such time, the Borrower may, at its own expense
(such expense to include any transfer fee payable to the Agent under Section
11.3(b) and any expense pursuant to Section 4) and in its sole discretion,
require such Lender to transfer and assign in whole (but not in part), without
recourse (in accordance with and subject to the terms and conditions of Section
11.3(b)), all of its interests, rights and obligations under this Credit
Agreement to an Eligible Assignee which shall assume such assigned obligations
(which assignee may be another Lender, if a Lender accepts such assignment);
provided that (a) such assignment shall not conflict with any law, rule or
regulation or order of any court or other Governmental Authority and (b) the
Borrower or such assignee shall have paid to the assigning Lender in immediately
available funds the principal of and interest accrued to the date of such
payment on the portion of the Loans hereunder held by such assigning Lender and
all other amounts owed to such assigning Lender hereunder, including amounts
owed pursuant to Sections 4.1 through 4.4.

    Section 5. CONDITIONS PRECEDENT

        5.1 Closing Conditions.

        The obligation of the Lenders to enter into this Credit

and governmental charges or levies imposed upon it, or upon its income or
profits, or upon any of its properties, before they shall become delinquent and
(b) all lawful claims (including claims for labor, materials and supplies)
which, if unpaid, might give rise to a Lien which is not permitted by Section
8.6 upon any of its properties; provided, however, that neither
the Borrower nor any Principal Subsidiary shall be required to pay any such tax,
assessment, charge, levy, claim or Indebtedness which is being contested in good
faith by appropriate proceedings and as to which adequate reserves therefor have
been established in accordance with GAAP, unless the failure to make any such
payment (i) would give rise to an immediate right to foreclose or collect on a
Lien securing such amounts or (ii) would have or reasonably be likely to have a
Material Adverse Effect.

        7.7 Insurance.

        The Borrower will, and will cause each of its Principal
Subsidiaries to, at all times maintain in full force and effect insurance
(including worker's compensation insurance, liability insurance, casualty
insurance and business interruption insurance) in such amounts, covering such
risks and liabilities and with such deductibles or self-insurance retentions as
are in accordance with normal industry practice; provided, however,
that the Borrower and its Principal Subsidiaries may self-insure to the same
extent as other companies engaged in similar businesses and to the extent
consistent with prudent business practice.

        7.8 Use of Proceeds.

        The proceeds of the Loans may be used solely (a) to repay on
the Closing Date the entire amount of all loans and other obligations
outstanding under the 2004 Credit Agreement, (b) to provide working capital and
(c) for other general corporate purposes; provided that proceeds of the Loans
may not be used to acquire another Person unless the board of directors (or
other comparable body) or shareholders, as appropriate, of such Person has
approved such acquisition.

        7.9 Audits/Inspections.

Borrower will, and will cause each of its Principal Subsidiaries to, permit
representatives appointed by the Agent, including, without limitation,
independent accountants, agents, attorneys, and appraisers to visit and inspect
the Borrower's and its Principal Subsidiaries' property, including its books and
records, its accounts receivable and inventory, the Borrower's and its Principal
Subsidiaries' facilities and their other business assets, and to make
photocopies or photographs thereof and to write down and record any information
such representative obtains and shall permit the Agent or its representatives to

        The Borrower will not, and will not permit any Principal
Subsidiary to, enter into any agreement that restricts the ability of any
Principal Subsidiary to pay dividends or other distributions with respect to any
shares of its capital stock; provided that it is understood and agreed that (a)
the foregoing covenant does not prohibit the Borrower or a Principal Subsidiary
from entering into agreements that contain financial covenants which require the
maintenance of a minimum net worth or compliance with financial ratios without
explicitly addressing the ability to pay dividends or make other distributions
with respect to shares of its capital stock and (b) the foregoing covenant does
not apply to limitations or restrictions imposed by law or in regulatory
proceedings or in the articles of incorporation of Wisconsin Pubic Service
Corporation as in effect on the date hereof or restrictions which arise only if
dividends on preferred stock issued by such Principal Subsidiary have not been
paid.

percent (25%) of Total Assets, as calculated as of the end of the most recent
fiscal quarter.

        8.4 Arm's-Length Transactions.

        9.1 Events of Default.

        An Event of Default shall exist upon the occurrence of any of
the following specified events (each an "Event of Default"):

        (a) Payment. The Borrower shall: (i) default in the
payment when due of any principal of any of the Loans or Letter of Credit
Obligations; or (ii) default, and such default shall continue for three or more
Business Days, in the payment when due of any interest on the Loans or Letter of
Credit Obligations or of any fees or other amounts owing hereunder, under any of
the other Credit Documents or in connection herewith.

        (b) Representations. Any representation, warranty or
statement made or deemed to be made by the Borrower (or any of its officers or
agents) herein, in any of the other Credit Documents, or in any statement or
certificate delivered or required to be delivered pursuant hereto or thereto
shall prove untrue in any material respect on the date as of which it was deemed
to have been made.

        (c) Covenants. The Borrower shall:

  
        (i) default in the due performance or observance of
        any term, covenant or agreement contained in Sections 7.1(a), 7.1(b),
        7.1(c), 7.1(d), 7.2, 7.3, 7.9, 8.2, 8.3 or 8.6; or

        (ii) default in the due performance or observance by
        it of any term, covenant or agreement (other than those referred to in
        subsections (a), (b) or (c)(i) of this Section 9.1) contained in this
        Credit Agreement or any other Credit Document and such default shall
        continue unremedied for a period of at least 30 days after the earlier
        of the Borrower becoming aware of such default or notice thereof given
        by the Agent.

  

        (d) Credit Documents. Any Credit Document shall fail
to be in full force and effect or the Borrower shall so assert or any Credit

privileges purported to be created thereby.

 

47

<PAGE>

 

        (e) Bankruptcy, etc. The occurrence of any of the
following with respect to the Borrower or any of its Principal Subsidiaries: (i)
a court or governmental agency having jurisdiction in the premises shall enter a
decree or order for relief in respect of the Borrower or any of its Principal
Subsidiaries in an involuntary case under any applicable bankruptcy, insolvency
or other similar law now or hereafter in effect, or appoint a receiver,
liquidator, assignee, custodian, trustee, sequestrator or similar official of
the Borrower or any of its Principal Subsidiaries or for any substantial part of
its property or ordering the winding up or liquidation of its affairs; or (ii)
an involuntary case under any applicable bankruptcy, insolvency or other similar
law now or hereafter in effect is commenced against the Borrower or any of its
Principal Subsidiaries and such petition remains unstayed and in effect for a
period of 60 consecutive days; or (iii) the Borrower or any of its Principal
Subsidiaries shall commence a voluntary case under any applicable bankruptcy,
insolvency or other similar law now or hereafter in effect, or consent to the
entry of an order for relief in an involuntary case under any such law, or
consent to the appointment or taking possession by a receiver, liquidator,
assignee, custodian, trustee, sequestrator or similar official of such Person or
any substantial part of its property or make any general assignment for the
benefit of creditors; or (iv) the Borrower or any of its Principal Subsidiaries
shall admit in writing its inability to pay its debts generally as they become
due or any action shall be taken by such Person in furtherance of any of the
aforesaid purposes.

        (f) Defaults Under Other Agreements. With respect to
any Indebtedness in excess of $35,000,000 (other than Indebtedness outstanding
under this Credit Agreement) of the Borrower or any of its Principal
Subsidiaries (i) the Borrower or any of its Principal Subsidiaries shall (A)
default in any payment (beyond the applicable grace period with respect thereto,
if any) with respect to any such Indebtedness, or (B) default (after giving
effect to any applicable grace period) in the observance or performance relating
to such Indebtedness or contained in any instrument or agreement evidencing,
securing or relating thereto, or any other event or condition shall occur or
condition exist other than non-material defaults under any First Mortgage
Indenture, the effect of which default or other event or condition is to cause,
or permit, the holder of the holders of such Indebtedness (or trustee or agent
on behalf of such holders) to cause (determined without regard to whether any
notice or lapse of time is required) any such Indebtedness to become due prior
to its stated maturity; or (ii) any such Indebtedness shall be declared due and
payable, or required to be prepaid other than by a regularly scheduled required
prepayment prior to the stated maturity thereof; or (iii) any such Indebtedness
shall mature and remain unpaid. The foregoing cross default provision shall not
apply to Indebtedness to the extent recourse to the Borrower is limited to
specific assets in a project financing; i.e., defaults under agreements
governing non-recourse project financing indebtedness are excluded.

        (g) Judgments. One or more judgments, orders, or
decrees shall be entered against the Borrower or any of its Principal
Subsidiaries involving a liability of $35,000,000 or more, in the aggregate (to
the extent not paid or covered by insurance provided by a carrier who has been
notified of, and has not disputed the claim made for payment of, the amount of
such judgment or order), and such judgments, orders or decrees shall continue
unsatisfied, undischarged and unstayed for a period ending on the first to occur
of (i) the last day on which such judgment, order or decree becomes final and
unappealable and, where applicable, with the status of a judicial lien or (ii)
60 days; provided that if such judgment, order or decree provides 

 

48

<PAGE>

 

 for
periodic payments over time then the Borrower shall have a grace period of 30
days with respect to each such periodic payment.

        (h) ERISA. The occurrence of any of the following
events or conditions if any of the same would be reasonably likely to have a
Material Adverse Effect: (A) any "accumulated funding deficiency," as
such term is defined in Section 302 of ERISA and Section 412 of the Code,
whether or not waived, shall exist with respect to any Plan, or any lien shall
arise on the assets of the Borrower, any of its Subsidiaries or any ERISA
Affiliate in favor of the PBGC or a Plan; (B) a Termination Event shall occur
with respect to a Single Employer Plan, which is, in the reasonable opinion of
the Agent, likely to result in the termination of such Plan for purposes of
Title IV of ERISA; (C) a Termination Event shall occur with respect to a
Multiemployer Plan or Multiple Employer Plan, which is, in the reasonable
opinion of the Agent, likely to result in (i) the termination of such Plan for
purposes of Title IV of ERISA, or (ii) the Borrower, any of its Subsidiaries or
any ERISA Affiliate incurring liability in connection with a withdrawal from,
reorganization of (within the meaning of Section 4241 of ERISA), or insolvency
(within the meaning of Section 4245 of ERISA) of such Plan; or (D) any
prohibited transaction (within the meaning of Section 406 of ERISA or Section
4975 of the Code) or breach of fiduciary responsibility shall occur which would
be reasonably likely to subject the Borrower, any of Subsidiaries or any ERISA
Affiliate to liability under Sections 406, 409, 502(i), or 502(1) of ERISA or
Section 4975 of the Code, or under any agreement or other instrument pursuant to
which the Borrower, any of Subsidiaries or any ERISA Affiliate has agreed or is
required to indemnify any person against any such liability.

        (i) Change of Control. The occurrence of any Change of
Control.

        9.2 Acceleration; Remedies.

        Upon the occurrence and during the continuance of an Event of
Default, the Agent may, and shall, upon the request and direction of the
Required Lenders, by written notice to the Borrower take any of the following
actions without prejudice to the rights of the Agent or any Lender to enforce
its claims against the Borrower, except as otherwise specifically provided for
herein:

  
        (i) Termination of Revolving Loan Commitments.
        Declare the Revolving Loan Commitments terminated whereupon the
        Revolving Loan Commitments shall be immediately terminated.

        (ii) Acceleration of Borrower Obligations.
        Declare the unpaid amount of all Borrower Obligations to be due
        whereupon the same shall be immediately due and payable without
        presentment, demand, protest or other notice of any kind, all of which
        are hereby waived by the Borrower.

        (iii) Cash Collateral. Direct the Borrower to
        pay (and the Borrower agrees that upon receipt of such notice, or upon
        the occurrence of an Event of Default under Section 9.1(e), it will
        immediately pay) to the Agent additional cash, to be held, without
        interest, by the Agent, for the benefit of the Lenders, in a cash
        collateral account as additional security for the Letter of Credit
        Obligations 

 

    49

  

<PAGE>

  
 

         in respect of subsequent drawings under all then outstanding
        Letters of Credit in an amount equal to the maximum aggregate amount
        which may be drawn under all Letters of Credits then outstanding.

        (iv) Enforcement of Rights. Enforce any and
        all rights and interests created and existing under the Credit
        Documents, including, without limitation, all rights of set-off.

  

Notwithstanding the foregoing, if an Event of Default
specified in Section 9.1(e) shall occur, then the Revolving Loan Commitments
shall automatically terminate and all Borrower Obligations, all accrued interest
in respect thereof, all accrued and unpaid fees and other indebtedness or
obligations owing to the Lenders and the Agent hereunder shall immediately
become due and payable without the giving of any notice or other action by the
Agent or the Lenders.

        Notwithstanding the fact that enforcement powers reside
primarily with the Agent, each Lender has, to the extent permitted by law, a
separate right of payment and shall be considered a separate
"creditor" holding a separate "claim" within the meaning of
Section 101(5) of the Bankruptcy Code or any other insolvency statute.

        9.3 Allocation of Payments After Event of
Default.

        Notwithstanding any other provisions of this Credit
Agreement, after the occurrence and during the continuance of an Event of
Default, all amounts collected or received by the Agent or any Lender on account
of amounts outstanding under any of the Credit Documents shall be paid over or
delivered as follows:

  
        FIRST, to the payment of all reasonable out-of-pocket
        costs and expenses (including without limitation reasonable attorneys'
        fees) of the Agent or-any of the Lenders in connection with enforcing
        the rights of the Lenders under the Credit Documents, pro rata as set
        forth below;

        SECOND, to payment of any fees owed to the Agent or
        any Lender, pro rata as set forth below;

        THIRD, to the payment of all accrued interest payable
        to the Lenders hereunder, pro rata as set forth below;

        FOURTH, to the payment of the outstanding principal
        amount of the Loans and unreimbursed drawings under Letters of Credit,
        and to the payment or cash collateralization of the outstanding Letters
        of Credit Obligations, pro rata as set forth below;

        FIFTH, to all other obligations which shall have
        become due and payable under the Credit Documents and not repaid
        pursuant to clauses "FIRST" through "FOURTH" above;
        and

 

    50

  

<PAGE>

  
 

        SIXTH, to the payment of the surplus, if any, to
        whoever may be lawfully entitled to receive such surplus.

  

In carrying out the foregoing, (a) amounts received shall be
applied in the numerical order provided until exhausted prior to application to
the next succeeding category; (b) each of the Lenders shall receive an amount
equal to its pro rata share (based on the proportion that the then outstanding
Loans, and Letter of Credit Obligations held by such Lender bears to the
aggregate then outstanding Loans and Letter of Credit Obligations), of amounts
available to be applied; and (c) to the extent that any amounts available for
distribution pursuant to clause "FOURTH" above are attributable to the
issued but undrawn amount of outstanding Letters of Credit, such amounts shall
be held by the Agent in a cash collateral account and applied (x) first, to
reimburse the Lenders from time to time for any drawings under such Letters of
Credit and (y) then, following the expiration of all Letters of Credit, to all
other obligations of the types described in clauses "FOURTH," and
"FIFTH" above in the manner provided in this Section 9.3.

    Section 10. AGENCY PROVISIONS

        10.1 Appointment.

        Each Lender hereby designates and appoints U.S. Bank National
Association as agent of such Lender to act as specified herein and the other
Credit Documents, and each such Lender hereby authorizes the Agent, as the agent
for such Lender, to take such action on its behalf under the provisions of this
Credit Agreement and the other Credit Documents and to exercise such powers and
perform such duties as are expressly delegated by the terms hereof and of the
other Credit Documents, together with such other powers as are reasonably
incidental thereto. Notwithstanding any provision to the contrary elsewhere
herein and in the other Credit Documents, the Agent shall not have any duties or
responsibilities, except those expressly set forth herein and therein, or any
fiduciary relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Credit Agreement or any of the other Credit Documents, or shall otherwise exist
against the Agent. The provisions of this Section are solely for the benefit of
the Agent and the Lenders and the Borrower shall not have any rights as a third
party beneficiary of the provisions hereof. In performing its functions and
duties under this Credit Agreement and the other Credit Documents, the Agent
shall act solely as agent of the Lenders and does not assume and shall not be
deemed to have assumed any obligation or relationship of agency or trust with or
for the Borrower.

any agents or attorneys-in-fact selected by it with reasonable care.

        10.3 Exculpatory Provisions.

        Neither the Agent nor any of its officers, directors,

    51

  

<PAGE>

 

 Documents
(except for its or such Person's own gross negligence or willful misconduct), or
responsible in any manner to any of the Lenders for any recitals, statements,
representations or warranties made by the Borrower contained herein or in any of
the other Credit Documents or in any certificate, report, statement or other
document referred to or provided for in, or received by the Agent under or in
connection herewith or in connection with the other Credit Documents, or
enforceability or sufficiency therefor of any of the other Credit Documents, or
for any failure of the Borrower to perform its obligations hereunder or
thereunder. The Agent shall not be responsible to any Lender for the
effectiveness, genuineness, validity, enforceability, collectibility or
sufficiency of this Credit Agreement, or any of the other Credit Documents or
for any representations, warranties, recitals or statements made herein or
therein or made by the Borrower in any written or oral statement or in any
financial or other statements, instruments, reports, certificates or any other
documents in connection herewith or therewith furnished or made by the Agent to
the Lenders or by or on behalf of the Borrower to the Agent or any Lender or be
required to ascertain or inquire as to the performance or observance of any of
the terms, conditions, provisions, covenants or agreements contained herein or
therein or as to the use of the proceeds of the Loans or of the existence or
possible existence of any Default or Event of Default or to inspect the
properties, books or records of the Borrower. The Agent is not a trustee for the
Lenders and owes no fiduciary duty to the Lenders.

        10.4 Reliance on Communications.

        The Agent shall be entitled to rely, and shall be fully
protected in relying, upon any note, writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message, statement, order or other document or conversation believed by it in
good faith to be genuine and correct and to have been signed, sent or made by
the proper Person or Persons and upon advice and statements of legal counsel
(including, without limitation, counsel to the Borrower, independent accountants
and other experts selected by the Agent with reasonable care). The Agent may
deem and treat the Lenders as the owner of its interests hereunder for all
purposes unless a written notice of assignment, negotiation or transfer thereof
shall have been filed with the Agent in accordance with Section 11.3(b). The
Agent shall be fully justified in failing or refusing to take any action under
this Credit Agreement or under any of the other Credit Documents unless it shall
first receive such advice or concurrence of the Required Lenders as it deems
appropriate or it shall first be indemnified to its satisfaction by the Lenders
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action. The Agent shall in all cases be
fully protected in acting, or in refraining from acting, hereunder or under any
of the other Credit Documents in accordance with a request of the Required
Lenders (or to the extent specifically provided in Section 11.6, all the
Lenders) and such request and any action taken or failure to act pursuant
thereto shall be binding upon all the Lenders (including their successors and
assigns).

        10.5 Notice of Default.

        The Agent shall not be deemed to have knowledge or notice of
the occurrence of any Default or Event of Default hereunder unless the Agent has
received notice from a Lender or the Borrower referring to the Credit Document,
describing such Default or Event of Default and stating that such notice is a
"notice of default." In the event that the Agent receives such a
notice, the Agent shall give prompt notice thereof to the Lenders. The Agent
shall take such

 

  
    52

  

<PAGE>

 

action with respect to such Default or Event of Default as shall
be reasonably directed by the Required Lenders.

        10.6 Non-Reliance on Agent and Other
Lenders.

        Each Lender expressly acknowledges that neither the Agent nor
any of its officers, directors, employees, agents, attorneys-in-fact or
affiliates has made any representations or warranties to it and that no act by
the Agent or any affiliate thereof hereinafter taken, including any review of
the affairs of the Borrower and its Subsidiaries, shall be deemed to constitute
any representation or warranty by the Agent to any Lender. Each Lender
represents to the Agent that it has, independently and without reliance upon the
Agent or any other Lender, and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, assets, operations, property, financial and other conditions,
prospects and creditworthiness of the Borrower or its Subsidiaries and made its
own decision to make its Extensions of Credit hereunder and enter into this
Credit Agreement. Each Lender also represents that it will, independently and
without reliance upon the Agent or any other Lender, and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own credit analysis, appraisals and decisions in taking or not taking action
under this Credit Agreement, and to make such investigation as it deems
necessary to inform itself as to the business, assets, operations, property,
financial and other conditions, prospects and creditworthiness of the Borrower
or its Subsidiaries. Except for notices, reports and other documents expressly
required to be furnished to the Lenders by the Agent hereunder, the Agent shall
not have any duty or responsibility to provide any Lender with any credit or
other information concerning the business, operations, assets, property,
financial or other conditions, prospects or creditworthiness of the Borrower or
its Subsidiaries which may come into the possession of the Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates.

        10.7 Indemnification.

        Each Lender agrees to indemnify the Agent in its capacity as
such (to the extent not reimbursed by the Borrower and without limiting the
obligation of the Borrower to do so), ratably according to its Commitment
Percentage, from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind whatsoever which may at any time (including without limitation at
any time following the payment in full of the Borrower Obligations) be imposed
on, incurred by or asserted against the Agent in its capacity as such in any way
relating to or arising out of this Credit Agreement or the other Credit
Documents or any documents contemplated by or referred to herein or therein or
the transactions contemplated hereby or thereby or any action taken or omitted
by the Agent under or in connection with any of the foregoing; provided that no
Lender shall be liable for the payment of any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from the gross negligence or willful
misconduct of the Agent or from any losses suffered by the Agent solely as a
result of the Borrower's failure to make payments as required pursuant to
Section 3.4(c). If any indemnity furnished to the Agent for any purpose shall,
in the opinion of the Agent, be insufficient or become impaired, the Agent may
call for additional indemnity and cease, or not commence, to do the acts
indemnified against until such additional indemnity is furnished. The 

53

<PAGE>

 

agreements
in this Section 10.7 shall survive the payment of the Borrower Obligations and
all other amounts payable hereunder and under the other Credit Documents.

        10.8 Agent in Its Individual Capacity.

        The Agent in its individual capacity and its Affiliates may
make loans to, accept deposits from and generally engage in any kind of business
with the Borrower and its Subsidiaries as though the Agent were not Agent
hereunder. With respect to the Loans made and all Borrower Obligations owing to
it, the Agent in its individual capacity shall have the same rights and powers
under this Credit Agreement as any Lender and may exercise the same as though
they were not Agent, and the terms "Lender" and "Lenders"
shall include the Agent in its individual capacity.

        10.9 Successor Agent.

        The Agent may, and at the request of the Required Lenders
shall, resign as the Agent upon 30 days notice to the Lenders. If the Agent
resigns under this Credit Agreement, the Required Lenders shall appoint from
among the Lenders a successor agent for the Lenders which successor agent shall
be approved by the Borrower. If no successor agent is appointed prior to the
effective date of the resignation of the Agent, the Agent may appoint, after
consulting with the Lenders and the Borrower, a successor agent from among the
Lenders. Upon the acceptance of its appointment as successor agent hereunder,
such successor agent shall succeed to all the rights, powers and duties of the
retiring Agent and the term "Agent" shall mean such successor agent
and the retiring Agent's appointment, powers and duties as Agent shall be
terminated. After any retiring Agent's resignation hereunder as Agent, the
provisions of this Section 10 and Section 11.5 shall inure to its benefit as to
any actions taken or omitted to be taken, by it while it was the Agent under
this Credit Agreement. If no successor agent has accepted appointment as the
Agent by the date which is 30 days following a retiring Agent's notice of
resignation, the retiring Agent's resignation shall nevertheless thereupon
become effective and the Lenders shall perform all of the duties of the Agent
hereunder until such time, if any, as the Required Lenders appoint a successor
agent with the Borrower's approval, as provided for above; provided that the
Borrower's approval shall not be required after and during the continuance of an
Event of Default.

    Section 11. MISCELLANEOUS

        11.1 Notices.

        Except as otherwise expressly provided herein, all notices
and other communications shall have been duly given and shall be effective (a)
when delivered, (b) when transmitted via telecopy (or other facsimile device) or
(c) the Business Day following the day on which the same has been delivered
prepaid to a reputable national overnight air courier service, in each case to
the respective parties at the address or telecopy numbers set forth on Schedule
11.1, or at such other address as such party may specify by written notice
to the other parties hereto.

        11.2 Right of Set-Off.

 

54

<PAGE>

 

        In addition to any rights now or hereafter granted under
applicable law or otherwise, and not by way of limitation of any such rights,
upon the occurrence and during the continuance of an Event of Default and the
commencement of remedies described in Section 9.2, each Lender is authorized at
any time and from time to time, without presentment, demand, protest or other
notice of any kind (all of which rights being hereby expressly waived), to set
off and to appropriate and apply any and all deposits (general or special) and
any other indebtedness at any time held or owing by such Lender (including,
without limitation branches, agencies or Affiliates of such Lender wherever
located) to or for the credit or the account of the Borrower against obligations
and liabilities of the Borrower to the Lenders hereunder, under the Notes, the
other Credit Documents or otherwise, irrespective of whether the Agent or the
Lenders shall have made any demand hereunder and although such obligations,
liabilities or claims, or any of them, may be contingent or unmatured. The
Borrower hereby agrees that any Person purchasing a participation in the Loans
and Revolving Loan Commitments hereunder pursuant to Section 11.3(c) may
exercise all rights of set-off with respect to its participation interest as
fully as if such Person were a Lender hereunder.

        11.3 Benefit of Agreement.

        (a) Generally. This Credit Agreement shall be binding
upon and inure to the benefit of and be enforceable by the respective successors
and assigns of the parties hereto; provided the Borrower may not assign and
transfer any of its interests without the prior written consent of the Lenders;
and provided, further, that the rights of each Lender to transfer, assign or
grant participations in its rights and/or obligations hereunder shall be limited
as set forth below in this Section 11.3.

        (b) Assignments. Each Lender may assign to one or more
Eligible Assignees all or a portion of its rights and obligations under this
Credit Agreement (including, without limitation, all or a portion of its Loans,
its Notes, and its Revolving Loan Commitment); provided, however,
that:

        (i) each such assignment shall be to an Eligible
        Assignee;

        (ii) except in the case of an assignment to another
        Lender or an assignment of all of a Lender's rights and obligations
        under this Credit Agreement, any such partial assignment shall be in an
        amount at least equal to $5,000,000 (or, if less, the remaining amount
        of the Revolving Loan Commitment being assigned by such Lender) and an
        integral multiple of $1,000,000 in excess thereof;

        (iii) each such assignment by a Lender shall be of a
        constant and not varying, percentage of all of its rights and
        obligations under this Credit Agreement and the Notes; and

        (iv) the parties to such assignment shall execute and
        deliver to the Agent for its acceptance an Assignment Agreement in
        substantially the form of Exhibit 11 .3(b), together with a processing
        fee (other than in connection with any assignment to an Affiliate of
        such Lender) from the assignor of $3,500.

 

55

<PAGE>

 

Upon execution, delivery, and acceptance of such Assignment
Agreement, the assignee thereunder shall be a party hereto and, to the extent of
such assignment, have the obligations, rights, and benefits of a Lender
hereunder and the assigning Lender shall, to the extent of such assignment,
relinquish its rights and be released from its obligations under this Credit
Agreement. Upon the consummation of any assignment pursuant to this Section
11.3(b), the assignor, the Agent and the Borrower shall make appropriate
arrangements so that, if required, new Notes are issued to the assignor and the
assignee. If the assignee is not incorporated under the laws of the United
States of America or a state thereof, it shall deliver to the Borrower and the
Agent certification as to exemption from deduction or withholding of taxes in
accordance with Section 4.4.

        By executing and delivering an assignment agreement in
accordance with this Section 11.3(b), the assigning Lender thereunder and the
assignee thereunder shall be deemed to confirm to and agree with each other and
the other parties hereto as follows: (A) such assigning Lender represents and
warrants that it is legally authorized to enter into such assignment agreement
and it is the legal and beneficial owner of the interest being assigned thereby
free and clear of any adverse claim created by such assigning Lender and the
assignee warrants that it is an Eligible Assignee; (B) except as set forth in
clause (A) above, such assigning Lender makes no representation or warranty and
assumes no responsibility with respect to any statements, warranties or
representations made in or in connection with this Credit Agreement, any of the
other Credit Documents or any other instrument or document furnished pursuant
hereto or thereto, or the execution, legality, validity, enforceability,
genuineness, sufficiency or value of this Credit Agreement, any of the other
Credit Documents or any other instrument or document furnished pursuant hereto
or thereto or the financial condition of the Borrower or its Subsidiaries or the
performance or observance by the Borrower of any of its obligations under this
Credit Agreement, any of the other Credit Documents or any other instrument or
document furnished pursuant hereto or thereto; (C) such assignee represents and
warrants that it is legally authorized to enter into such assignment agreement;
(D) such assignee confirms that it has received a copy of this Credit Agreement,
the other Credit Documents and such other documents and information as it has
deemed appropriate to make its own credit analysis and decision to enter into
such assignment agreement; (E) such assignee will independently and without
reliance upon the Agent, such assigning Lender or any other Lender, and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Credit Agreement and the other Credit Documents; (F) such assignee appoints
and authorizes the Agent to take such action on its behalf and to exercise such
powers under this Credit Agreement or any other Credit Document as are delegated
to the Agent by the terms hereof or thereof, together with such powers as are
reasonably incidental thereto; and (G) such assignee agrees that it will perform
in accordance with their terms all the obligations which by the terms of this
Credit Agreement and the other Credit Documents are required to be performed by
it as a Lender.

        (c) Register. The Agent shall maintain a copy of each
Assignment Agreement delivered to and accepted by it and a register for the
recordation of the names and addresses of the Lenders and the Revolving Loan
Commitment of, and principal amount of the Loans owing to, each Lender from time
to time (the "Register"). The entries in the Register shall be
conclusive and binding for all purposes, absent manifest error, and the
Borrower, the Agent and the Lenders may treat each Person whose name is recorded
in the Register as a Lender hereunder 

 

56

<PAGE>

 

 for all purposes of this Credit Agreement.
The Register shall be available for inspection by the Borrower or any Lender at
any reasonable time and from time to time upon reasonable prior notice.

        (d) Acceptance. Upon its receipt of an Assignment
Agreement executed by the parties thereto, together with any Note subject to
such assignment and payment of the processing fee, the Agent shall, if such
Assignment Agreement has been completed and is in substantially the form of Exhibit
11.3(b) hereto, (i) accept such Assignment Agreement, (ii) record the
information contained therein in the Register and (iii) give prompt notice
thereof to the parties thereto.

        (e) Participations. Each Lender may sell
participations to one or more Persons in all or a portion of its rights,
obligations or rights and obligations under this Credit Agreement (including all
or a portion of its Revolving Loan Commitment, its Notes and its Loans); provided,
however, that (i) such Lender's obligations under this Credit Agreement
shall remain unchanged, (ii) such Lender shall remain solely responsible to the
other parties hereto for the performance of such obligations, (iii) the
participant shall be entitled to the benefit of the yield protection provisions
contained in Sections 4.1 through 4.4, inclusive, but only to the extent that
such Lender is entitled to payment or reimbursement under such Sections, and the
right of set-off contained in Section 11.2 and (iv) the Borrower shall continue
to deal solely and directly with such Lender in connection with such Lender's
rights and obligations under this Credit Agreement, and such Lender shall retain
the sole right to enforce the obligations of the Borrower relating to its Loans
and its Notes and to approve any amendment, modification, or waiver of any
provision of this Credit Agreement (other than amendments, modifications, or
waivers decreasing the amount of principal of or the rate at which interest is
payable on such Loans or Notes, extending any scheduled principal payment date
or date fixed for the payment of interest on such Loans or Notes, or extending
its Revolving Loan Commitment).

        (f) Nonrestricted Assignments. Notwithstanding any
other provision set forth in this Credit Agreement, any Lender may at any time
assign and pledge all or any portion of its Loans and its Notes to any Federal
Reserve Bank as collateral security pursuant to Regulation A and any Operating
Circular issued by such Federal Reserve Bank. No such assignment shall release
the assigning Lender from its obligations hereunder.

        (g) Information. Any Lender may furnish any
information concerning the Borrower and its Subsidiaries in the possession of
such Lender from time to time to assignees and participants (including
prospective assignees and participants); provided that the furnishing of such
information shall be subject to the provisions of Section 11.11 below.

        (h) SPC's. Notwithstanding anything to the contrary
contained herein, any Lender (a "Granting Lender") may grant to
a special purpose funding vehicle (an "SPC") the option to fund all or
any part of any Loan that such Granting Lender would otherwise be obligated to
fund pursuant to this Credit Agreement; provided that (i) nothing
herein shall constitute a commitment by any SPC to fund any Loan, (ii) if an SPC
elects not to exercise such option or otherwise fails to fund all or any part of
such Loan, the Granting Lender shall be obligated to fund such Loan pursuant to
the terms hereof, (iii) no SPC shall have any voting rights pursuant to Section
11.6 (all such voting rights shall be retained by the Granting Lenders), 

 

57

<PAGE>

 

 (iv)
with respect to notices, payments and other matters hereunder, the Borrower, the
Agent and the Lenders shall not be obligated to deal with an SPC, but may limit
their communications and other dealings relevant to such SPC to the applicable
Granting Lender, and (v) with respect to the funding of any Loan by an SPC, the
Borrower shall not have to pay any greater cost, or incur any greater expense,
under the provisions of Section 4 of this Credit Agreement or otherwise, than if
all Loans were funded by the applicable Granting Lender without the involvement
of an SPC. The funding of a Loan by an SPC hereunder shall utilize the Revolving
Loan Commitment of the Granting Lender to the same extent that, and as if, such
Loan were funded by such Granting Lender. Each party hereto hereby agrees that
no SPC shall be liable for any indemnity or payment under this Credit Agreement
for which a Lender would otherwise be liable for so long as, and to the extent,
the Granting Lender provides such indemnity or makes such payment. In
furtherance of the foregoing, each party hereto hereby agrees (which agreements
shall survive termination of this Credit Agreement) that, prior to the date that
is one year and one day after the payment in full of all outstanding commercial
paper or other senior indebtedness of any SPC, it will not institute against, or
join any other Person in instituting against, such SPC any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings under the
laws of the United States or any State thereof. Notwithstanding anything to the
contrary contained in this Credit Agreement, any SPC may disclose on a
confidential basis any non-public information relating to its funding of Loans
to any rating agency, commercial paper dealer or provider of any surety or
guarantee to such SPC. This clause (h) may not be amended without the prior
written consent of each Granting Lender, all or any part of whose Loan is being
funded by an SPC at the time of such amendment.

        11.4 No Waiver; Remedies Cumulative.

        No failure or delay on the part of the Agent or any Lender in
exercising any right, power or privilege hereunder or under any other Credit
Document and no course of dealing between the Borrower and the Agent or any
Lender shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege hereunder or under any other Credit
Document preclude any other or further exercise thereof or the exercise of any
other right, power or privilege hereunder or thereunder. The rights and remedies
provided herein are cumulative and not exclusive of any rights or remedies which
the Agent or any Lender would otherwise have. No notice to or demand on the
Borrower in any case shall entitle the Borrower to any other or further notice
or demand in similar or other circumstances or constitute a waiver of the rights
of the Agent or the Lenders to any other or further action in any circumstances
without notice or demand.

        11.5 Payment of Expenses, etc.

        The Borrower agrees to: (i) pay all reasonable out-of-pocket
costs and expenses of the Agent and the Lead Arranger in connection with (A) the
negotiation, preparation, execution and delivery and administration of this
Credit Agreement and the other Credit Documents and the documents and
instruments referred to therein (including, without limitation, legal fees of
one counsel for the Agent) and (B) any amendment, waiver or consent relating
hereto and thereto including, but not limited to, any such amendments, waivers
or consents resulting from or related to any work-out, renegotiation or
restructure relating to the performance by the Borrower under this Credit
Agreement, (ii) pay all reasonable out-of-pocket costs and expenses of the Agent
and 

 

58

<PAGE>

 

 the Lenders in connection with (A) enforcement of the Credit Documents and
the documents and instruments referred to therein (including, without
limitation, in connection with any such enforcement, the reasonable fees and
disbursements of counsel for the Agent and each of the Lenders) and (B) any
bankruptcy or insolvency proceeding of the Borrower and (iii) indemnify the
Agent, the Lead Arranger and each Lender, its officers, directors, employees,
representatives, affiliates and agents from and hold each of them harmless
against any and all losses, liabilities, claims, damages or expenses incurred by
any of them as a result of, or arising out of, or in any way related to, or by
reason of, any investigation, litigation or other proceeding (whether or not the
Agent, the Lead Arranger or any Lender is a party thereto) related to the
entering into and/or performance of any Credit Document or the use of proceeds
of any Loans (including other extensions of credit) hereunder or the
consummation of any other transactions contemplated in any Credit Document,
including, without limitation, the reasonable fees and disbursements of counsel
incurred in connection with any such investigation, litigation or other
proceeding (but excluding any such losses, liabilities, claims, damages or
expenses to the extent incurred by reason of gross negligence or willful
misconduct on the part of the Person to be indemnified or such Person's
employer, employee or co-employee); provided that the foregoing indemnity by the
Borrower shall not extend to disputes solely among the Lenders or litigation
commenced by the Borrower which (a) seeks enforcement of any of the Borrower's
rights hereunder and (b) is determined in a final judgment adverse to the Agent
and the Lenders.

        11.6 Amendments, Waivers and Consents.

        Neither this Credit Agreement, nor any other Credit Document
nor any of the terms hereof or thereof may be amended, changed, waived,
discharged or terminated unless such amendment, change, waiver, discharge or
termination is in writing and signed by the Required Lenders and the Borrower;
provided that no such amendment, change, waiver, discharge or termination shall
without the consent of each Lender:

        (a) extend the Maturity Date, or postpone or extend the time
for any payment or prepayment of principal;

        (b) reduce the rate or extend the time of payment of interest
(other than as a result of waiving the applicability of any post-default
increase in interest rates) thereon or fees or other amounts payable hereunder;

        (c) reduce or waive the principal amount of any Loan;

        (d) increase or extend the Revolving Loan Commitment of a
Lender (it being understood and agreed that a waiver of any Default or Event of
Default shall not constitute a change in the terms of any Revolving Loan
Commitment of any Lender);

        (e) release the Borrower from its obligations under the
Credit Documents;

        (f) amend, modify or waive any provision of this Section 11.6
or Section 3.6, 3.8, 4.1, 4.2, 4.3, 4.4, 9.1(a), 11.2, 11.3 or 11.5;

        (g) reduce any percentage specified in, or otherwise modify,
the definition of Required Lenders; or

 

59

<PAGE>

 

        (h) consent to the assignment or transfer by the Borrower of
any of its rights and obligations under (or in respect of) the Credit Documents.

        No provision of Section 2.9 or Section 10 may be amended or
modified without the consent of the Agent.

        Notwithstanding the fact that the consent of all the Lenders
is required in certain circumstances as set forth above, each Lender is entitled
to vote as such Lender sees fit on any reorganization plan that affects the
Loans, and each Lender acknowledges that the provisions of Section 1126(c) of
the Bankruptcy Code supersedes the unanimous consent provisions set forth
herein.

        11.7 Counterparts/Telecopy.

        This Credit Agreement may be executed in any number of
counterparts, each of which where so executed and delivered shall be an
original, but all of which shall constitute one and the same instrument.
Delivery of executed counterparts by telecopy shall be as effective as an
original and shall constitute a representation that an original will be
delivered.

        11.8 Headings.

        The headings of the sections and subsections hereof are
provided for convenience only and shall not in any way affect the meaning or
construction of any provision of this Credit Agreement.

        11.9 Defaulting Lender.

        Each Lender understands and agrees that if such Lender is a
Defaulting Lender then it shall not be entitled to vote on any matter requiring
the consent of the Required Lenders or to object to any matter requiring the
consent of all the Lenders; provided, however, that all other
benefits and obligations under the Loan Documents shall apply to such Defaulting
Lender.

        11.10 Survival of Indemnification and
Representations and Warranties.

        All indemnities set forth herein and all representations and
warranties made herein shall survive the execution and delivery of this Credit
Agreement, the making of the Loans and the repayment of the Loans and other
obligations and the termination of the Revolving Loan Commitments hereunder.

        11.11 Confidentiality.

        Neither the Agent nor any Lender shall disclose any
Confidential Information to any Person, without the prior written consent of the
Borrower, other than (a) to the Agent's or such Lender's Affiliates and their
officers, directors, employees, agents, attorneys, accountants and advisors (it
being understood that the Persons to whom such disclosure is made will be
informed of the confidential nature of such Confidential Information and such
person shall have agreed to keep such Confidential Information confidential on
substantially the same terms as provided herein) and, as contemplated by Section
11.3, to actual or prospective assignees and

 participants, and, in each such
case, then only on a confidential basis, (b) as required by any law, rule or
regulation or by judicial process, (c) to any rating agency when required by it
to do so; provided that, prior to any such disclosure, such rating agency shall
undertake to preserve the confidentiality of any Confidential Information
relating to the Borrower received by it from such Lender, (d) as requested or
required by any state, federal or foreign authority or examiner regulating banks
or banking, (e) to protect, preserve, exercise or enforce the Agent's or such
Lender's rights under or pursuant to this Agreement or any Note, and (f) to
perform any of the Agent's or such Lender's obligations under or pursuant to
this Agreement or any Note.

        If any provision of any of the Credit Documents is determined

pursuant to Section 326 of the USA Patriot Act of 2001, 31 U.S.C. Section 5318:

        IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW
ACCOUNT. To help the government fight the funding of terrorism and money
laundering activities, Federal law requires all financial institutions to
obtain, verify, and record information that identifies each person or entity
that opens an account, including any deposit account, treasury management
account, loan, other extension of credit, or other financial services product.
What this means for the Borrower: When the Borrower opens an account, if the
Borrower is an individual, the Agent and the Lenders will ask for the Borrower's
name, residential address, tax identification number, date of birth, and other
information that will allow the Agent and the Lenders to identify the Borrower,
and, if the Borrower is not an individual, the Agent and the Lenders will ask
for the Borrower's name, tax identification number, business address, and other
information that will allow the Agent and the Lenders to identify the Borrower.
The Agent and the Lenders may also ask, if the Borrower is an individual, to see
the Borrower's driver's license or other identifying documents, and, if the
Borrower is not an individual, to see the Borrower's legal organizational
documents or other identifying documents.

        11.18 Entirety.

        This Credit Agreement together with the other Credit
Documents represent the entire agreement of the parties hereto and thereto, and
supersede all prior agreements and understandings, oral or written, if any,
including any commitment letters or correspondence relating to the Credit
Documents or the transactions contemplated herein and therein.
