each Canadian Term Lender to maintain an adequate supply of blank forms of B/As
for acceptance under this Agreement. CBIL recognizes and agrees that all B/As
signed and/or endorsed on its behalf by any Canadian Term Lender shall bind CBIL
as fully and effectually as if manually signed and duly issued by authorized
officers of CBIL. Each Canadian Term Lender is hereby authorized to issue such
B/As endorsed in blank in such face amounts as may be determined by such Lender;
provided that the aggregate face amount thereof is equal to the aggregate face
--------
amount of B/As required to be accepted by such Lender. No Canadian Term Lender
shall be liable for any damage, loss or claim arising by reason of any loss or
improper use of any such instrument unless such loss or improper use results
from the gross negligence or wilful misconduct of such Lender. Each Canadian
Term Lender shall maintain a record with respect to B/As (i) received by it from
the Canadian Agent in blank hereunder, (ii) voided by it for any reason, (iii)
accepted and purchased by it hereunder and (iv) canceled at their respective
maturities. Each Canadian Term Lender further agrees to retain such records in
the manner and for the periods provided in applicable provincial or Federal
statutes and regulations of Canada and to provide such records to CBIL upon its
request and at its expense. Upon request by CBIL, a Lender shall cancel all
forms of B/A that have been pre-signed or pre-endorsed on behalf of CBIL and
that are held by such Lender and are not required to be issued pursuant to this
Agreement.

          (e) Drafts of CBIL to be accepted as B/As hereunder shall be signed as
set forth in paragraph (d) above. Notwithstanding that any Person whose
signature appears on any B/A may no longer be an authorized signatory for any of
the Lenders or CBIL at the date of issuance of such B/A, such signature shall
nevertheless be valid and sufficient for all purposes as if such authority had
remained in force at the time of such issuance and any such B/A so signed shall
be binding on CBIL.

          (f) Upon acceptance of a B/A by a Lender, such Lender shall purchase,
or arrange the purchase of, such B/A from CBIL at the Discount Rate for such
Lender applicable to such B/A accepted by it and provide to the Canadian Agent
the Discount Proceeds for the account of CBIL as provided in Section 2.06. The
acceptance fee payable by CBIL to a Lender under Section 2.12 in respect of each
B/A accepted by such Lender shall be set off against the Discount Proceeds
payable by such Lender under this paragraph.

Notwithstanding the foregoing, in the case of any B/A Drawing resulting from the
conversion or continuation of a B/A Drawing or Canadian Term Loan pursuant to
Section 2.07, the net amount that would otherwise be payable to CBIL by each
Lender pursuant to this paragraph will be applied as provided in Section
2.07(f).

          (g) Each Lender may at any time and from time to time hold, sell,
rediscount or otherwise dispose of any or all B/A's accepted and purchased by
it.

          (h) Each B/A accepted and purchased hereunder shall mature at the end
of the Contract Period applicable thereto.

          (i) CBIL waives presentment for payment and any other defence to
payment of any amounts due to a Lender in respect of a B/A accepted and
purchased by it pursuant to this Agreement which might exist solely by reason of
such B/A being held, at the maturity thereof, by such Lender in its own right
and CBIL agrees not to claim any days of grace if such Lender as holder sues
CBIL on the B/A for payment of the amounts payable by CBIL thereunder. On the
specified maturity date of a B/A, or such earlier date as may be required
pursuant to the provisions of this Agreement, CBIL shall pay the Lender that has
accepted and purchased such B/A the full face amount of such B/A, and after such
payment CBIL shall have no further liability in respect of such B/A and such
Lender shall be entitled to all benefits of, and be responsible for all payments
due to third parties under, such B/A. Amounts owed by CBIL at the maturity dates
of B/As may not be voluntarily prepaid.

          (j) At the option of CBIL and any Lender, B/A's under this Agreement
to be accepted by that Lender may be issued in the form of depository bills for
deposit with The Canadian Depository for Securities Limited pursuant to the
Depository Bills and Notes Act (Canada). All depository bills so issued shall be
governed by the provisions of this Section 2.04.

          SECTION 2.05. Letters of Credit. (a) General. Upon the Effective Date,
                        -----------------      -------
the Existing Letters of Credit will automatically, without any action on the
part of any Person, be deemed to be Letters of Credit issued hereunder for the
account of the Company for all purposes of this Agreement and the other Loan
Documents. Subject to the terms and conditions set forth herein, the Company may
request the issuance of Letters of Credit for its own account, in a form
reasonably acceptable to the US Agent and the applicable Issuing Bank, at any
time and from time to time during the Revolving Availability Period. In the
event of any inconsistency between the terms and conditions of this Agreement
and the terms and conditions of any form of letter of credit application or
other agreement submitted by the Company to, or entered into by the Company
with, any Issuing Bank relating to any Letter of Credit (including the Existing
Letters of Credit), the terms and conditions of this Agreement shall control.

          (b) Notice of Issuance, Amendment, Renewal, Extension; Certain
              ----------------------------------------------------------
Conditions. To request the issuance of a Letter of Credit (or the amendment,
----------
renewal or extension of an outstanding Letter of Credit), the Company shall hand
deliver or telecopy (or transmit by electronic communication, if arrangements
for doing so have been approved by the applicable Issuing Bank) to the
applicable Issuing Bank and the US Agent (reasonably in advance of the requested
date of issuance, amendment, renewal or extension) a notice requesting the
issuance of a Letter of Credit, or identifying the Letter of Credit to be
amended, renewed or extended, and specifying the date of issuance, amendment,
renewal or extension (which shall be a Business Day), the date on which such
Letter of Credit is to expire (which shall comply with paragraph (c) of below),
the amount of such Letter of Credit, the name and address of the beneficiary
thereof and such other information as shall be necessary to enable the
applicable Issuing Bank to prepare, amend, renew or extend such Letter of
Credit. If requested by the applicable Issuing Bank, the Company also shall
submit a letter of credit application on such Issuing Bank's standard form in
connection with any request for a Letter of Credit. A Letter of Credit shall be
issued, amended, renewed or extended only if (and upon issuance, amendment,
<PAGE>

                                                                              46

renewal or extension of each Letter of Credit the Company shall be deemed to
represent and warrant that), after giving effect to such issuance, amendment,
renewal or extension (i) the LC Exposure shall not exceed US$15,000,000 and (ii)
the aggregate Revolving Exposures shall not exceed the aggregate Revolving
Commitments.

          (c) Expiration Date. Each Letter of Credit shall expire at or prior to
              ---------------
the close of business on the earlier of (i) the date one year after the date of
the issuance of such Letter of Credit (or, in the case of any renewal or
extension thereof, one year after such renewal or extension) and (ii) the date
that is five Business Days prior to the Revolving Maturity Date.

          (d) Participations. By the issuance of a Letter of Credit (or an
              --------------
amendment to a Letter of Credit increasing the amount thereof) and without any
further action on the part of the Issuing Bank or the Lenders, the applicable
Issuing Bank hereby grants to each Revolving Lender, and each Revolving Lender
hereby acquires from such Issuing Bank, a participation in such Letter of Credit
equal to such Lender's Applicable Percentage of the aggregate amount available
to be drawn under such Letter of Credit. In consideration and in furtherance of
the foregoing, each Revolving Lender hereby absolutely and unconditionally
agrees to pay to the US Agent, for the account of the applicable Issuing Bank,
such Lender's Applicable Percentage of each LC Disbursement made by such Issuing
Bank and not reimbursed by the Company on the date due or financed with the
proceeds of an ABR Borrowing as provided in paragraph (e) of this Section, or of
any reimbursement payment required to be refunded to the Company for any reason.
Each Lender acknowledges and agrees that its obligation to acquire
participations pursuant to this paragraph in respect of Letters of Credit is
absolute and unconditional and shall not be affected by any circumstance
whatsoever, including any amendment, renewal or extension of any Letter of
Credit or the occurrence and continuance of a Default or reduction or
termination of the Commitments, and that each such payment shall be made without
any offset, abatement, withholding or reduction whatsoever.

          (e) Reimbursement. If any Issuing Bank shall make any LC Disbursement
              -------------
in respect of a Letter of Credit, the Company shall reimburse such LC
Disbursement by paying to the US Agent an amount equal to such LC Disbursement
not later than 12:00 noon, New York City time, on the date that such LC
Disbursement is made, if the Company shall have received notice of such LC
Disbursement prior to 10:00 a.m., New York City time, on such date, or, if such
notice has not
<PAGE>

                                                                              47

been received by the Company prior to such time on such date, then not later
than 12:00 noon, New York City time, on (i) the Business Day that the Company
receives such notice, if such notice is received prior to 10:00 a.m., New York
City time, on the day of receipt, or (ii) the Business Day immediately following
the day that the Company receives such notice, if such notice is not received
prior to such time on the day of receipt; provided that, if such LC Disbursement
                                          --------
is not less than US$2,000,000, the Company may, subject to the conditions to
borrowing set forth herein, request (and if the Company fails to reimburse such
LC Disbursement when due the Company shall be deemed to have requested) in
accordance with Section 2.03 that such LC Disbursement be financed with an ABR
Revolving Borrowing in an equivalent amount and, to the extent so financed, the
Company's obligation to make such payment shall be discharged and replaced by
the resulting ABR Revolving Borrowing (and the time for reimbursement of such LC
Disbursement shall automatically be extended to the Business Day following such
request or deemed request). If the Company fails to reimburse such LC
Disbursement when due, whether directly or through an ABR Borrowing as provided
above, the US Agent shall notify each Revolving Lender of the applicable LC
Disbursement, the payment then due from the Company in respect thereof and such
Lender's Applicable Percentage thereof. Promptly following receipt of such
notice, each Revolving Lender shall pay to the US Agent its Applicable
Percentage of the payment then due from the Company, in the same manner as
provided in Section 2.06 with respect to Loans made by such Lender (and Section
2.06 shall apply, mutatis mutandis, to the payment obligations of the Revolving
                  ------- --------
Lenders), and the US Agent shall promptly pay to the applicable Issuing Bank the
amounts so received by it from the Revolving Lenders. Promptly following receipt
by the US Agent of any payment from the Company pursuant to this paragraph, the
US Agent shall distribute such payment to the applicable Issuing Bank or, to the
extent that Revolving Lenders have made payments pursuant to this paragraph to
reimburse such Issuing Bank, then to such Lenders and such Issuing Bank as their
interests may appear. Any payment made by a Revolving Lender pursuant to the
second preceding sentence to reimburse any Issuing Bank for any LC Disbursement
(other than the funding of ABR Revolving Loans as contemplated above) shall not
constitute a Loan and shall not relieve the Company of its obligation to
reimburse such LC Disbursement.

          (f) Obligations Absolute. The Company's obligation to reimburse LC
              --------------------
Disbursements as provided in paragraph (e) of this Section shall be absolute,
unconditional and irrevocable, and shall be performed
<PAGE>

                                                                              48

strictly in accordance with the terms of this Agreement under any and all
circumstances whatsoever and irrespective of (i) any lack of validity or
enforceability of any Letter of Credit or this Agreement, or any term or
provision therein, (ii) any draft or other document presented under a Letter of
Credit proving to be forged, fraudulent or invalid in any respect or any
statement therein being untrue or inaccurate in any respect, (iii) payment by
the applicable Issuing Bank under a Letter of Credit against presentation of a
draft or other document that does not comply with the terms of such Letter of
Credit or (iv) any other event or circumstance whatsoever, whether or not
similar to any of the foregoing, that might, but for the provisions of this
Section, constitute a legal or equitable discharge of, or provide a right of
setoff against, the Company's obligations hereunder. None of the US Agent, the
Lenders or the Issuing Banks, or any of their Related Parties, shall have any
liability or responsibility by reason of or in connection with the issuance or
transfer of any Letter of Credit or any payment or failure to make any payment
thereunder (irrespective of any of the circumstances referred to in the
preceding sentence), any error, omission, interruption, loss or delay in
transmission or delivery of any draft, notice or other communication under or
relating to any Letter of Credit (including any document required to make a
drawing thereunder), any error in interpretation of technical terms or any
consequence arising from causes beyond the control of any Issuing Bank; provided
                                                                        --------
that the foregoing shall not be construed to excuse any Issuing Bank from
liability to the Company to the extent of any direct damages (as opposed to
consequential damages, claims in respect of which are hereby waived by the
Company to the extent permitted by applicable law) suffered by the Company that
are caused by such Issuing Bank's failure to exercise care when determining
whether drafts and other documents presented under a Letter of Credit comply
with the terms thereof. The parties hereto expressly agree that, in the absence
of gross negligence or wilful misconduct on the part of any Issuing Bank (as
finally determined by a court of competent jurisdiction), such Issuing Bank
shall be deemed to have exercised care in each such determination. In
furtherance of the foregoing and without limiting the generality thereof, the
parties agree that, with respect to documents presented which appear on their
face to be in substantial compliance with the terms of a Letter of Credit, the
applicable Issuing Bank may, in its sole discretion, either accept and make
payment upon such documents without responsibility for further investigation,
regardless of any notice or information to the contrary, or refuse to accept and
make payment upon such documents if such documents are not in strict compliance
with the terms of such Letter of Credit.

                                                                              49

          (g) Disbursement Procedures. The applicable Issuing Bank shall,
              -----------------------
promptly following its receipt thereof, examine all documents purporting to
represent a demand for payment under a Letter of Credit. The applicable Issuing
Bank shall promptly notify the US Agent and the Company by telephone (confirmed
by telecopy) of such demand for payment and whether such Issuing Bank has made
or will make an LC Disbursement thereunder; provided that any failure to give or
                                            --------
delay in giving such notice shall not relieve the Company of its obligation to
reimburse such Issuing Bank and the Revolving Lenders with respect to any such
LC Disbursement.

          (h) Interim Interest. If any Issuing Bank shall make any LC
              ----------------
Disbursement, then, unless the Company shall reimburse such LC Disbursement in
full on the date such LC Disbursement is made, the unpaid amount thereof shall
bear interest, for each day from and including the date such LC Disbursement is
made to but excluding the date that the Company reimburses such LC Disbursement,
at (i) prior to the date on which reimbursement in respect of such LC
Disbursement is due, the rate per annum then applicable to ABR Revolving Loans
under Section 2.13(a) and (ii) on and after the date on which reimbursement in
respect of such LC Disbursement is due, the rate per annum then applicable to
overdue ABR Revolving Loans under Section 2.13(d). Interest accrued pursuant to
this paragraph shall be for the account of the applicable Issuing Bank, except
that interest accrued on and after the date of payment by any Revolving Lender
pursuant to paragraph (e) of this Section to reimburse such Issuing Bank shall
be for the account of such Lender to the extent of such payment.

          (i) Replacement of the Issuing Bank. Any Issuing Bank may be replaced
              -------------------------------
at any time by written agreement among the Company, the US Agent, the replaced
Issuing Bank and the successor Issuing Bank. The US Agent shall notify the
Lenders of any such replacement of an Issuing Bank. At the time any such
replacement shall become effective, the Company shall pay all unpaid fees
accrued for the account of the replaced Issuing Bank pursuant to Section
2.12(c). From and after the effective date of any such replacement, (i) the
successor Issuing Bank shall have all the rights and obligations of the replaced
Issuing Bank under this Agreement with respect to Letters of Credit to be issued
thereafter and (ii) references herein to the term "Issuing Bank" shall be deemed
to refer to such successor or to any previous Issuing Bank, or to such successor
and all previous Issuing Banks, as the context shall require. After the
replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain
a party hereto and shall continue to have all the rights and obligations of an
Issuing Bank
<PAGE>

                                                                              50

under this Agreement with respect to Letters of Credit issued by it prior to
such replacement, but shall not be required to issue additional Letters of
Credit.

          (j) Cash Collateralization. If any Event of Default shall occur and be
              ----------------------
continuing, on the Business Day that the Company receives notice from the US
Agent or the Required Lenders (or, if the maturity of the Loans has been
accelerated, Revolving Lenders with LC Exposures representing a majority of the
total LC Exposure) demanding the deposit of cash collateral pursuant to this
paragraph, the Company shall deposit in an account with the US Agent, in the
name of the US Agent and for the benefit of the Lenders, an amount in cash equal
to the LC Exposure as of such date plus any accrued and unpaid interest thereon;
provided that the obligation to deposit such cash collateral shall become
--------
effective immediately, and such deposit shall become immediately due and
payable, without demand or other notice of any kind, upon the occurrence of any
Event of Default with respect to the Company described in clause (f) or (g) of
Article VII. Each such deposit shall be held by the US Agent as collateral for
the payment and performance of the obligations of the Borrowers under this
Agreement. The US Agent shall have exclusive dominion and control, including the
exclusive right of withdrawal, over such account. Other than any interest earned
on the investment of such deposits, which investments shall be made at the
option and sole discretion of the US Agent (in a manner not inconsistent with
that in which a reasonable person would invest his or her own funds) and at the
Company's risk and expense, such deposits shall not bear interest. Interest or
profits, if any, on such investments shall accumulate in such account. Moneys in
such account shall be applied by the US Agent to reimburse the applicable
Issuing Bank for LC Disbursements for which it has not been reimbursed and, to
the extent not so applied, shall be held for the satisfaction of the
reimbursement obligations of the Company for the LC Exposure at such time or, if
the maturity of the Loans has been accelerated (but subject to the consent of
Revolving Lenders with LC Exposures representing a majority of the total LC
Exposure), be applied to satisfy other obligations of the Borrowers under this
Agreement. If the Company is required to provide an amount of cash collateral
hereunder as a result of the occurrence of an Event of Default, such amount (to
the extent not applied as aforesaid) shall be returned to the Company within
three Business Days after all Events of Default have been cured or waived.

          (k) Additional Issuing Banks. The Company may at any time and from
              ------------------------
time to time, designate one or more
<PAGE>

                                                                              51

additional Lenders to act as an issuing bank under this Agreement with the
consent of the US Agent (which consent shall not be unreasonably withheld) and
such Lender. Any Lender designated as an issuing bank pursuant to this paragraph
(k) shall be deemed to be and shall have all the rights and obligations of an
"Issuing Bank" hereunder.

          SECTION 2.06. Funding. (a) Each Lender shall make each Loan to be made
                        -------
by it and disburse the Discount Proceeds of each B/A to be accepted and
purchased by it hereunder on the proposed date of such Loan or such acceptance
and purchase by wire transfer of immediately available funds by 12:00 noon in
the Applicable Jurisdiction to the account of the Applicable Agent most recently
designated by it for such purpose by notice to the Lenders. The Applicable Agent
will make such funds available to the applicable Borrower by promptly crediting
the amounts so received, in like funds, to an account of such Borrower
maintained with the Applicable Agent in the Applicable Jurisdiction and
designated by such Borrower in the applicable Borrowing Request or request for
the acceptance and purchase of B/As; provided that (i) no proceeds shall be made
                                     --------
available in the case of any conversion or continuation of Borrowings or B/A
Drawings pursuant to Section 2.07 and (ii) ABR Revolving Loans made to finance
the reimbursement of an LC Disbursement as provided in Section 2.05(e) shall be
remitted by the US Agent to the applicable Issuing Bank.

          (b) Unless the Applicable Agent shall have received notice from a
Lender prior to the proposed date of any Borrowing or acceptance and purchase of
B/As that such Lender will not make available to the Applicable Agent such
Lender's share of the proceeds thereof, the Applicable Agent may assume that
such Lender has made such share available on such date in accordance with
paragraph (a) of this Section and may, in reliance upon such assumption, make
available to the applicable Borrower a corresponding amount. In such event, if a
Lender has not in fact made its share of such proceeds available to the
Applicable Agent, then the applicable Lender and the applicable Borrower
severally agree to pay to the Applicable Agent forthwith on demand such
corresponding amount with interest thereon, for each day from and including the
date such amount is made available to such Borrower to but excluding the date of
payment to the Applicable Agent, at (i) in the case of such Lender, a rate
determined by the Applicable Agent in accordance with banking industry rules on
interbank compensation or (ii) in the case of such Borrower, the interest rate
applicable to ABR Loans or the Canadian Base Rate Loans, as the case may be.

                                                                              52

          SECTION 2.07. Rate Elections. (a) Each Revolving Borrowing and Term
                        --------------
Borrowing initially shall be of the Type specified in the applicable Borrowing
Request and, in the case of a Eurodollar Borrowing, shall have an initial
Interest Period as specified in such Borrowing Request. Each B/A Drawing shall
have a Contract Period as specified in the applicable request therefor. After
the initial Borrowings and B/A Drawings, the Borrowers may elect to convert and
continue such Borrowings and B/A Drawings as provided in this Section (it being
understood that no B/A Drawing may be converted or continued other than at the
end of the Contract Period applicable thereto). The Borrowers may elect
different options with respect to different portions of the affected Borrowings
or B/A Drawings, in which case each such portion shall be allocated ratably
among the Lenders holding the Loans comprising such Borrowings or accepting the
B/As comprising such B/A Drawings, as the case may be, and any Loans or B/As
resulting from an election made with respect to any such portion shall be
considered a separate Borrowing or B/A Drawing. Notwithstanding any other
provision of this Section, no Canadian Term Borrowing or B/A Drawing may be
converted into or continued as a B/A Drawing with a Contract Period ending after
the next date on which a payment is to become due under Section 2.10(b) unless,
after giving effect to such conversion or continuation, the amount of such
payment does not exceed the sum of (i) the aggregate outstanding principal
amount of the Canadian Term Borrowings and (ii) the aggregate face amount of the
outstanding B/As with Contract Periods ending prior to such date.

          (b) To make an election pursuant to this Section, the applicable
Borrower shall notify the Applicable Agent of such election by telephone (i) in
the case of an election that will result in a Borrowing or the continuation of a
Borrowing, by the time that a Borrowing Request would be required under Section
2.03 if the applicable Borrower were requesting a Borrowing of the Type and
Class resulting or continuing from such election to be made on the effective
date of such election and (b) in the case of an election that will result in a
B/A Drawing or the continuation of a B/A Drawing, by the time specified in
Section 2.04(c). Each such telephonic Rate Election Request shall be irrevocable
and shall be confirmed promptly by hand delivery or telecopy to the Applicable
Agent of a written Rate Election Request in a form approved by the Applicable
Agent and signed by the applicable Borrower.
<PAGE>

                                                                              53

          (c)   Each telephonic and written Rate Election Request shall specify
the following information in compliance with Section 2.02 or 2.04:

          (i)   the Borrowing or B/A Drawing to which such Rate Election Request
     applies and, if different options are being elected with respect to
     different portions thereof, the portions thereof to be allocated to each
     resulting Borrowing or B/A Drawing (in which case the information to be
     specified pursuant to clauses (iii) and (iv) below shall be specified for
     each resulting Borrowing or B/A Drawing);

          (ii)  the effective date of the election made pursuant to such Rate
     Election Request, which shall be a Business Day;

          (iii) in the case of an election with respect to a US Term Borrowing
     or a Revolving Borrowing, whether an ABR Borrowing or a Eurodollar
     Borrowing is elected, and in the case of an election with respect to a
     Canadian Term Borrowing or a B/A Drawing, whether a Canadian Term Borrowing
     or a B/A Drawing is elected; and

          (iv)  in the case of an election of a Eurodollar Borrowing, the
     Interest Period to be applicable thereto, which shall be a period
     contemplated by the definition of the term "Interest Period", and in the
     case of an election of a B/A Drawing, the Contract Period to be applicable
     thereto, which shall be a period contemplated by the definition of the term
     "Contract Period".

If any such Rate Election Request requests a Eurodollar Borrowing or B/A Drawing
but does not specify an Interest Period or Contract Period, then the applicable
Borrower shall be deemed to have selected an Interest Period of one month's
duration or a Contract Period of one month's duration, as the case may be.

          (d)   Promptly following receipt of an Rate Election Request, the
Applicable Agent shall advise each applicable Lender of the details thereof and
of such Lender's portion of each resulting Borrowing or B/A Drawing.

          (e)   If the applicable Borrower fails to deliver a timely Rate
Election Request with respect to a Eurodollar Borrowing or B/A Drawing prior to
the end of the Interest Period or Contract Period applicable thereto, then,
unless such Borrowing or B/A Drawing is repaid as provided herein, at the end of
such Interest Period or Contract Period such

Borrowing or B/A Drawing shall be converted to an ABR Borrowing or a Canadian
Base Rate Borrowing, as applicable. Notwithstanding any contrary provision
hereof, if an Event of Default has occurred and is continuing and the US Agent,
at the request of the Required Lenders, so notifies the Borrowers, then, so long
as an Event of Default is continuing (i) no outstanding Borrowing may be
converted to or continued as a Eurodollar Borrowing or a B/A Drawing and (ii)
unless repaid, each Eurodollar Borrowing or B/A Drawing shall be converted to an
ABR Borrowing or a Canadian Base Rate Borrowing, as applicable, at the end of
the Interest Period or Contract Period applicable thereto.

          (f) Upon the conversion of any Canadian Term Borrowing or the
continuation of any B/A Drawing (or portion thereof) to or as a B/A Drawing, the
net amount that would otherwise be payable to CBIL by each Lender pursuant to
Section 2.04(f) in respect of such new B/A Drawing shall be applied against the
principal of the Canadian Term Loan made by such Lender (in the case of a
conversion), or CBIL's obligation to reimburse such Lender in respect of the
B/As accepted by such Lender under Section 2.04(i) (in the case of a
continuation), as part of such Canadian Term Borrowing to be so converted or
such maturing B/A Drawing to be so continued, and CBIL shall pay to such Lender
an amount equal to the difference between the principal amount of such Canadian
Term Loan or the aggregate face amount of such maturing B/As, as the case may
be, and such net amount.

          (g) The conversion or continuation of any
Borrowing or B/A drawing shall not constitute a repayment of amounts outstanding
or a new advance of funds hereunder.

          SECTION 2.08. Termination and Reduction of Commitments. (a) Unless
                        ----------------------------------------
previously terminated, (i) the US Term Commitments and Canadian Term Commitments
shall terminate at 5:00 p.m., New York City time, on the Effective Date and (ii)
the Revolving Commitments shall terminate on the Revolving Maturity Date.

          (b) The Company may at any time terminate, or from time to time
reduce, the Commitments of any Class; provided that (i) each reduction of the
                                      --------
Commitments of any Class shall be in an amount that is an integral multiple of
US$1,000,000 or C$100,000, as the case may be, and not less than US$5,000,000 or
C$500,000, as the case may be, and (ii) the Company shall not terminate or
reduce the Revolving Commitments if, after giving effect to any concurrent
prepayment of the Revolving Loans in accordance with Section 2.11, the aggregate
Revolving Exposures would exceed the aggregate Revolving Commitments.

                                                                              55

          (c) The Company shall notify the Facility Agents of any election to
terminate or reduce the Commitments under paragraph (b) above at least three
Business Days prior to the effective date of such termination or reduction,
specifying such election and the effective date thereof. Promptly following
receipt of any notice, the Facility Agents shall advise the Lenders of the
contents thereof. Each notice delivered by the Company pursuant to this Section
shall be irrevocable; provided that a notice of termination of the Revolving
                      --------
Commitments delivered by the Company may state that such notice is conditioned
upon the effectiveness of other credit facilities (or any other transaction
intended to replace the financing hereunder), in which case such notice may be
revoked by the Company (by notice to the US Agent on or prior to the specified
effective date) if such condition is not satisfied. Any termination or reduction
of the Commitments of any Class shall be permanent. Each reduction of the
Commitments of any Class shall be made ratably among the Lenders in accordance
with their respective Commitments of such Class.

          SECTION 2.09. Repayment of Loans; Evidence of Debt. (a) The Company
                        ------------------------------------
hereby unconditionally promises to pay (i) to the US Agent for the account of
each Revolving Lender the then unpaid principal amount of each Revolving Loan of
such Lender on the Revolving Maturity Date and (ii) to the US Agent for the
account of each US Term Lender the then unpaid principal amount of each US Term
Loan of such Lender as provided in Section 2.10. CBIL hereby unconditionally
promises to pay to the Canadian Agent for the account of each Canadian Term
Lender the then unpaid principal amount of each Canadian Term Loan of such
Lender and the face amount of each B/A accepted by such Lender as provided in
Section 2.10.

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

          (c) The Facility Agents shall maintain accounts in which they shall
record (i) the amount of each Loan made hereunder, the Class and Type thereof
and the Interest Period applicable thereto, (ii) the amount of any principal or
interest due and payable or to become due and payable from each Borrower to each
Lender hereunder and (iii) the amount of any sum received by the Facility Agents
hereunder for the accounts of the Lenders and each Lender's share thereof.

          (d) The entries made in the accounts maintained pursuant to paragraph
(b) or (c) of this Section shall be prima facie evidence of the existence and
                                    ----- -----
amounts of the obligations recorded therein; provided that the failure of any

Lender or Agent to maintain such accounts or any error therein shall not in any
manner affect the obligations of the Borrowers to repay the Loans in accordance
with the terms of this Agreement.

          (e) Any Lender may request that Loans of any Class made by it be
evidenced by a promissory note. In such event, the applicable Borrower shall
prepare, execute and deliver to such Lender a promissory note payable to the
order of such Lender (or, if requested by such Lender, to such Lender and its
registered assigns) and in a form approved by the Applicable Agent. Thereafter,
the Loans evidenced by such promissory note and interest thereon shall at all
times (including after assignment pursuant to Section 9.04) be represented by
one or more promissory notes in such form payable to the order of the payee
named therein (or, if such promissory note is a registered note, to such payee
and its registered assigns).

shall be due and payable on the US Term Maturity Date and (ii) all Canadian Term
Borrowings and Obligations in respect of B/As shall be due and payable on the
Canadian Term Maturity Date.

          (d) Any prepayment of a Term Borrowing of either Class or amounts to
become due in respect of B/As shall be applied to reduce the subsequent
scheduled repayments in respect of such Class or such B/A Drawings to be made
pursuant to this Section ratably in accordance with the amounts thereof. If the
initial aggregate amount of the Lenders' Term Commitments of either Class
exceeds the aggregate principal amount of Term Loans of such Class that are made
(and, in the case of the Canadian Term Commitments, the aggregate face amount of
the B/As that are accepted) on the Effective Date, then the scheduled repayments
in respect of such Class or B/A Drawings to be made pursuant to this Section
shall be ratably reduced by an aggregate amount equal to such excess.

          (e) Prior to any repayment of any Term Borrowings of either Class or
B/A Drawings hereunder, the Borrower shall select the Borrowing or Borrowings of
the applicable Class or B/A Drawings to be repaid and shall notify the
Applicable Agent by telephone (confirmed by telecopy) of such selection not
later than 11:00 a.m. in the Applicable Jurisdiction three Business Days before
the scheduled date of such repayment. Each repayment of a Term Borrowing or B/A
Drawings shall be applied ratably to the Loans included in the repaid Borrowing
or the B/As included in such B/A Drawing. Repayments of Term Borrowings shall be
accompanied by accrued interest on the amount repaid.

          SECTION 2.11. Prepayment of Loans. (a) Each Borrower shall have the
                        --------------------
right at any time and from time to time to prepay any Borrowing in whole or in
part, without penalty or premium (but subject to Section 2.16), subject to the
requirements of this Section.

          (b) In the event and on each occasion that the sum of the Revolving
Exposures exceeds the total Revolving Commitments, the Company shall prepay
Revolving Borrowings (or, if no such Borrowings are outstanding, deposit cash
collateral in an account with the US Agent pursuant to Section 2.05(j)) in an
aggregate amount equal to such excess.

          (c) In the event and on each occasion that any Net Proceeds are
received by or on behalf of the Company or any Subsidiary in respect of any
Prepayment Event resulting in aggregate Net Proceeds in excess of US$2,000,000,
the Borrowers shall, within five Business Days after such Net Proceeds are
received, prepay Term Borrowings and amounts owed in respect of outstanding B/As
in an aggregate amount equal to (i) in the case of Net Proceeds of an event
referred to in clause (a), (b) or (d) of the definition of "Prepayment Event",
100% of such Net Proceeds, and (ii) in the case of Net Proceeds of an event
referred to in clause (c) of the definition of "Prepayment Event", (A) at any
time when the Leverage Ratio exceeds 2.5 to 1.0, 50% of such Net Proceeds (or
such lesser amount as shall result in the Leverage Ratio, calculated to include
the effect of any such application of Net Proceeds, to be not greater than 2.5
to 1.0) and (ii) at any other time, 0% of such Net Proceeds; provided, that the
                                                             --------
Net Proceeds of any event referred to in clause (a) or (b) of the definition of
"Prepayment Event", to the extent such event shall relate to assets of CBIL and
its subsidiaries, shall be applied only to prepay Canadian Term Loans and
amounts owed by CBIL in respect of outstanding B/As.

                                                                              60

          (d) Following the end of each fiscal year of the Company, commencing
with the fiscal year ending December 31, 2001, the Borrowers shall prepay Term
Borrowings and amounts owed in respect of outstanding B/As in an aggregate
amount equal to 50% of Excess Cash Flow for such fiscal year. Each prepayment
pursuant to this paragraph shall be made within five days after the date on
which financial statements are delivered pursuant to Section 5.01(a) with
respect to the fiscal year for which Excess Cash Flow is being calculated (and
in any event within 95 days after the end of such fiscal year).

          (e) Prior to any optional or mandatory prepayment of Borrowings or
amounts owing in respect of outstanding B/As hereunder, the Borrowers shall
select the Borrowing or Borrowings and B/As to be prepaid and shall specify such
selection in the notice of such prepayment pursuant to paragraph (f) of this
Section. In the event of any optional or mandatory prepayment of Term Borrowings
and amounts owing in respect of outstanding B/As made at a time when US Term
Borrowings and Canadian Term Borrowings and/or B/As remain outstanding, the
Borrowers shall, except as required by the proviso in paragraph (c) above,
select Term Borrowings and B/As to be prepaid so that the aggregate amount of
such prepayment is allocated between the US Term Borrowings and Canadian Term
Borrowings and/or B/As ratably based on the aggregate principal amount of
outstanding Borrowings of each such Class and the aggregate face amount of all
outstanding B/As.

          (f) The Borrowers shall notify the Facility Agents by telephone
(confirmed by telecopy) of any prepayment hereunder (i) in the case of
prepayment of a Eurodollar Borrowing, not later than 11:00 a.m., New York City
time, three Business Days before the date of prepayment or (ii) in the case of
prepayment of any other Borrowing or any amount owed in respect of outstanding
B/As, not later than 11:00 a.m. in the Applicable Jurisdiction, one Business Day
before the date of prepayment. Each such notice shall be irrevocable and shall
specify the prepayment date, the principal amount of each Borrowing or portion
thereof to be prepaid and, in the case of a mandatory prepayment, a reasonably
detailed calculation of the amount of such prepayment; provided that, if a
                                                       --------
notice of optional prepayment is given in connection with a conditional notice
of termination of the Revolving Commitments as contemplated by Section 2.08,
then such notice of prepayment may be revoked if such notice of termination is
revoked in accordance with Section 2.08. Promptly following receipt of any such
notice, the Applicable Agent shall advise the affected Lenders of the contents
thereof. Each partial

                                                                              61

prepayment of any Borrowing shall be in an amount that would be permitted in the
case of an advance of a Borrowing of the same Type as provided in Section 2.02,
except as necessary to apply fully the required amount of a mandatory
prepayment. Each prepayment of a Borrowing shall be applied ratably to the Loans
included in the prepaid Borrowing. Prepayments shall be accompanied by accrued
interest to the extent required by Section 2.13.

          (g) Amounts to be applied pursuant to this Section 2.11 or Section
7.02 to prepay amounts to become due with respect to outstanding B/As shall be
deposited in the Prepayment Account (as defined below). The Canadian Agent shall
apply any cash deposited in the Prepayment Account allocable to amounts to
become due in respect of B/As on the last day of their respective Contract
Periods until all amounts due in respect of outstanding B/As have been prepaid
or until all the allocable cash on deposit has been exhausted. For purposes of
this Agreement, the term "Prepayment Account" shall mean an account established
                          ------------------
by CBIL with the Canadian Agent and over which the Canadian Agent shall have
exclusive dominion and control, including the exclusive right of withdrawal for
application in accordance with this paragraph (g). The Canadian Agent will, at
the request of CBIL, invest amounts on deposit in the Prepayment Account in
short term cash equivalents that mature prior to the last day of the applicable
Contract Periods of the B/As to be prepaid; provided, however, that (i) the
                                            -----------------
Canadian Agent shall not be required to make any investment that, in its sole
judgment, would require or cause the Canadian Agent to be in, or would result in
any, violation of any law, statute, rule or regulation and (ii) the Canadian
Agent shall have no obligation to invest amounts on deposit in the Prepayment
Account if a Default or Event of Default shall have occurred and be continuing.
Other than any interest earned on such investments (which shall be for the
account of the CBIL, to the extent not necessary for the prepayment of B/As in
accordance with this Section 2.11), the Prepayment Account shall not bear
interest. Interest or profits, if any, on such investments shall be deposited in
the Prepayment Account and reinvested and disbursed as specified above. If the
maturity of the Loans and all amounts due hereunder has been accelerated
pursuant to Article VII, the Canadian Agent may, in its sole discretion, apply
all amounts on deposit in the Prepayment Account to satisfy any of the Canadian
Obligations. CBIL hereby grants to the Canadian Agent, for its benefit and the
benefit of the Canadian Secured Parties, a security interest in its Prepayment
Account to secure the Canadian Obligations.

          SECTION 2.12. Fees. (a) The Company agrees to pay to the US Agent for
                        ----
the account of each Lender a commitment fee, which shall accrue at the
Applicable Rate on the average daily unused amount of each Commitment of such
Lender during the period from and including the date of this Agreement to but
excluding the date on which such Commitment terminates. Accrued commitment fees
shall be payable in arrears on the last day of March, June, September and
December of each year and on each date on which the Commitments of any Class
shall terminate, commencing on the first such date to occur after the date
hereof. All commitment fees will be computed on the basis of a year of 360 days
and will be payable for the actual number of days elapsed (including the first
day but excluding the last day). For purposes of computing commitment fees with
respect to Revolving Commitments, a Revolving Commitment of a Lender shall be
deemed to be used to the extent of the outstanding Revolving Loans and LC
Exposure of such Lender.

          (b) CBIL agrees to pay to the Canadian Agent, for the account of each
Canadian Term Lender, on each date on which B/As are accepted hereunder, an
acceptance fee computed by multiplying (i) the product of the face amount of
each B/A accepted by such Lender and the Applicable Rate by (ii) a fraction the
numerator of which is the number of days in the Contract Period applicable to
such B/A and the denominator of which is 365.

          (c) The Company agrees to pay (i) to the US Agent for the account of
each Revolving Lender a participation fee with respect to its participations in
Letters of Credit, which shall accrue at the same Applicable Rate as interest on
Eurodollar Revolving Loans on the average daily amount of such Lender's LC
Exposure (excluding any portion thereof attributable to unreimbursed LC
Disbursements) during the period from and including the Effective Date to but
excluding the later of the date on which such Lender's Revolving Commitment
terminates and the date on which such Lender ceases to have any LC Exposure, and
(ii) to each Issuing Bank a fronting fee, which shall accrue at the rate of .25%
per annum on the daily average aggregate outstanding amount of all Letters of
Credit issued by it, during the period from and including the Effective Date to
but excluding the later of the date of termination of the Revolving Commitments
and the date on which there ceases to be any LC Exposure with respect to Letters
of Credit issued by such Issuing Bank, as well as such Issuing Bank's standard
fees with respect to the issuance, amendment, renewal or extension of any Letter
of Credit or processing of drawings thereunder. Participation fees and fronting

June, September and December of each year shall be payable on the third Business
Day following such last day, commencing on the first such date to occur after
the Effective Date; provided that all such fees shall be payable on the date on
                    --------
which the Revolving Commitments terminate and any such fees accruing after the
date on which the Revolving Commitments terminate shall be payable on demand.
Any other fees payable to any Issuing Bank pursuant to this paragraph shall be
payable within 30 days after demand in writing. All participation fees and
fronting fees shall be computed on the basis of a year of 360 days and shall be
payable for the actual number of days elapsed (including the first day but
excluding the last day).

          (d) The Borrowers agree to pay to the Facility Agents, for their own
account, fees payable in the amounts and at the times separately agreed upon
between the Borrowers and the Facility Agents.

          (e) All fees payable hereunder shall be paid on the dates due, in
immediately available funds, to the applicable Agent (or to the applicable
Issuing Bank, in the case of fees payable to it) for distribution, in the case
of commitment fees and participation fees, to the Lenders entitled thereto. Fees
due hereunder which shall have been paid shall not be refundable under any
circumstances.

          SECTION 2.13. Interest. (a) The Loans comprising each ABR Borrowing
                        --------
shall bear interest at the Alternate Base Rate plus the Applicable Rate.

          (b) The Loans comprising each Eurodollar
Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period
in effect for such Borrowing plus the Applicable Rate.

          (c) The Loans comprising each Canadian Base Rate Borrowing shall bear
interest at the Canadian Base Rate plus the Applicable Rate.

          (d) Notwithstanding the foregoing, if any principal of or interest on
any Loan or any fee or other amount payable by the Borrowers hereunder is not
paid when due, whether at stated maturity, upon acceleration or otherwise, such
overdue amount shall bear interest, after as well as before judgment, at a rate
per annum equal to (i) in the case of overdue principal of any Loan, 2% per
annum plus the rate otherwise applicable to such Loan as provided in the
preceding paragraphs of this Section or (ii) in the case of any other amount, 2%
per annum plus (A) in the case of any amounts payable in US Dollars, the rate
applicable to

                                                                              64

ABR Loans as provided in paragraph (a) of this Section and (B) in the case of
any amounts payable in Canadian Dollars, the rate applicable to Canadian Base
Rate Loans as provided in paragraph (b) of this Section.

          (e) Accrued interest on each Loan shall be payable in arrears on each
Interest Payment Date for such Loan and, in the case of Revolving Loans, upon
termination of the Revolving Commitments; provided that (i) interest accrued
                                          --------
pursuant to paragraph (d) of this Section shall be payable on demand, (ii) in
the event of any repayment or prepayment of any Loan (other than a prepayment of
an ABR Revolving Loan prior to the end of the Revolving Availability Period),
accrued interest on the principal amount repaid or prepaid shall be payable on
the date of such repayment or prepayment and (iii) in the event of any
conversion of any Eurodollar Loan prior to the end of the current Interest
Period therefor, accrued interest on such Loan shall be payable on the effective
date of such conversion.

          (f) All interest hereunder shall be computed on the basis of a year of
360 days, except that interest computed by reference to (i) the Alternate Base
Rate at times when the Alternate Base Rate is based on the Prime Rate and (ii)
the Canadian Base Rate shall be computed on the basis of a year of 365 days (or
366 days in a leap year), and in each case shall be payable for the actual
number of days elapsed (including the first day but excluding the last day). The
applicable Alternate Base Rate, Adjusted LIBO Rate or Canadian Base Rate shall
be determined by the Applicable Agent, and such determination shall be
conclusive absent manifest error.

          SECTION 2.14. Alternate Rate of Interest. If prior to the commencement
                        --------------------------
of any Interest Period for a Eurodollar Borrowing:

          (a) the US Agent determines (which determination shall be conclusive
     absent manifest error) that adequate and reasonable means do not exist for
     ascertaining the Adjusted LIBO Rate for such Interest Period; or

          (b) the US Agent is advised by the Required Lenders that the Adjusted
     LIBO Rate for such Interest Period will not adequately and fairly reflect
     the cost to such Lenders of making or maintaining their Loans included in
     such Borrowing for such Interest Period;
<PAGE>

                                                                              65

     then the US Agent shall give notice thereof to the Company and the Lenders
     by telephone or telecopy as promptly as practicable thereafter and, until
     the US Agent notifies the Company and the Lenders that the circumstances
     giving rise to such notice no longer exist, (i) any Rate Election Request
     that requests the conversion of any Borrowing to, or continuation of any
     Borrowing as, a Eurodollar Borrowing shall be ineffective and (ii) if any
     Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be
     made as an ABR Borrowing.

               SECTION 2.15. Increased Costs. (a) If any Change in Law shall:
                             ----------------

               (i) impose, modify or deem applicable any reserve, special
          deposit or similar requirement against assets of, deposits with or for
          the account of, or credit extended by, any Lender (except any such
          reserve requirement reflected in the Adjusted LIBO Rate) or Issuing
          Bank; or

              (ii) impose on any Lender or Issuing Bank or the London interbank
          market any other condition affecting this Agreement or Eurodollar
          Loans made by such Lender or any Letter of Credit or participation
          therein;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Eurodollar Loan or obtaining funds for the
purchase of B/As (or of maintaining its obligation to make any such Loan or to
accept and purchase B/As) or to increase the cost to such Lender or Issuing Bank
of participating in, issuing or maintaining any Letter of Credit or to reduce
the amount of any sum received or receivable by such Lender or Issuing Bank
hereunder (whether of principal, interest or otherwise), then the Borrowers will
pay to such Lender or Issuing Bank, as the case may be, such additional amount
or amounts as will compensate such Lender or such Issuing Bank, as the case may
be, for such additional costs incurred or reduction suffered, as determined by
such Lender or Issuing Bank in good faith.

          (b) If any Lender or Issuing Bank determines in good faith that any
Change in Law regarding capital requirements has or would have the effect of
reducing the rate of return on such Lender's or Issuing Bank's capital or on the
capital of such Lender's or Issuing Bank's holding company, if any, as a
consequence of this Agreement or the Loans made or B/As accepted and purchased
by, or participations in Letters of Credit held by, such Lender, or the Letters
of Credit issued by such Issuing Bank, to a
<PAGE>

                                                                              66

level below that which such Lender or Issuing Bank or such Lender's or Issuing
Bank's holding company could have achieved but for such Change in Law (taking
into consideration such Lender's or Issuing Bank's policies and the policies of
such Lender's or Issuing Bank's holding company with respect to capital
adequacy), then from time to time the Borrowers will pay to such Lender or
Issuing Bank, as the case may be, such additional amount or amounts as will
compensate such Lender or Issuing Bank or such Lender's or Issuing Bank's
holding company for any such reduction suffered.

          (c) A certificate of a Lender or Issuing Bank setting forth the amount
or amounts necessary to compensate such Lender or Issuing Bank or its holding
company, as the case may be, as specified in paragraph (a) or (b) of this
Section, shall be delivered to the Borrowers and shall be conclusive absent
manifest error. The Borrowers shall pay such Lender or such Issuing Bank, as the
case may be, the amount shown as due on any such certificate within 10 days
after receipt thereof absent manifest error in the determination of such amount.

          (d) Failure or delay on the part of any Lender or any Issuing Bank to
demand compensation pursuant to this Section shall not constitute a waiver of
such Lender's or such Issuing Bank's right to demand such compensation; provided
                                                                        --------
that the Borrowers shall not be required to compensate a Lender or an Issuing
Bank pursuant to this Section for any increased costs or reductions incurred
more than 90 days prior to the date that such Lender or such Issuing Bank, as
the case may be, notifies the Borrowers of the Change in Law giving rise to such
increased costs or reductions and of such Lender's or such Issuing Bank's
intention to claim compensation therefor; provided further that, if the Change
                                          -------- -------
in Law 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.

          SECTION 2.16. Break Funding Payments. In the event of (a) the payment
                        ----------------------
of any principal of any Eurodollar Loan other than on the last day of an
Interest Period applicable thereto (including as a result of an Event of
Default), (b) the conversion of any Eurodollar Loan other than on the last day
of the Interest Period applicable thereto, (c) the failure to borrow, convert,
continue or prepay any Revolving Loan or Term Loan or to issue B/As for
acceptance and purchase on the date specified in any notice delivered pursuant
hereto (regardless of whether such notice may be revoked under Section 2.11(f)
and is revoked in
<PAGE>

                                                                              67

accordance therewith), or (d) the assignment of any Eurodollar Loan or right to
receive payment in respect of any B/A other than on the last day of the Interest
Period or Contract Period applicable thereto as a result of a request by the
Company pursuant to Section 2.19, then, in any such event, the applicable
Borrower shall compensate each Lender for the loss, cost and expense
attributable to such event. In the case of a Eurodollar Loan, such loss, cost or
expense to any Lender shall be deemed to include an amount determined by such
Lender to be the excess, if any, of (i) the amount of interest which would have
accrued on the principal amount of such Loan had such event not occurred, at the
Adjusted LIBO Rate that would have been applicable to such Loan, for the period
from the date of such event to the last day of the then current Interest Period
therefor (or, in the case of a failure to borrow, convert or continue, for the
period that would have been the Interest Period for such Loan), over (ii) the
amount of interest which would accrue on such principal amount for such period
at the interest rate which such Lender would bid were it to bid, at the
commencement of such period, for US Dollar deposits of a comparable amount and
period from other banks in the eurodollar market. A certificate of any Lender
setting forth any amount or amounts that such Lender is entitled to receive
pursuant to this Section shall be delivered to the applicable Borrower and shall
be conclusive absent manifest error. The applicable Borrower shall pay such
Lender the amount shown as due on any such certificate within 10 days after
receipt thereof absent manifest error in the determination of such amount.

          SECTION 2.17. Taxes. (a) Any and all payments by or on account of any
                        -----
obligation of any Loan Party hereunder or under any other Loan Document shall be
made free and clear of and without deduction for any Indemnified Taxes or Other
Taxes; provided that if a Loan Party shall be required to deduct any Indemnified
       --------
Taxes or Other Taxes from such payments, then (i) the sum payable shall be
increased as necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this Section) the
Applicable Agent, Lender or Issuing Bank (as the case may be) receives an amount
equal to the sum it would have received had no such deductions been made, (ii)
the Loan Party shall make such deductions and (iii) the Loan Party shall pay the
full amount deducted to the relevant Governmental Authority in accordance with
applicable law.

          (b) In addition, the Borrowers shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.
<PAGE>

                                                                              68

          (c) The Borrowers shall indemnify each Agent, each Lender and each
Issuing Bank, within 15 days after written demand therefor, for the full amount
of any Indemnified Taxes or Other Taxes paid by such Agent, Lender or Issuing
Bank, as the case may be, on or with respect to any payment by or on account of
any obligation of any Loan Party hereunder or under any other Loan Document
(including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section) and any penalties, interest
and reasonable expenses arising therefrom or with respect thereto, whether or
not such Indemnified Taxes or Other Taxes were correctly or legally imposed or
asserted by the relevant Governmental Authority. A certificate as to the amount
of such payment or liability delivered to the Borrowers by a Lender or an
Issuing Bank, or by an Agent on its own behalf or on behalf of a Lender or an
Issuing Bank, shall be conclusive absent manifest error in the determination of
such amount.

          (d) As soon as practicable after any payment of Indemnified Taxes or
Other Taxes by any Loan Party to a Governmental Authority, the Borrowers shall
deliver to the Facility Agents the original or a certified copy of a receipt
issued by such Governmental Authority evidencing such payment, a copy of the
return reporting such payment or other evidence of such payment reasonably
satisfactory to the Facility Agents.

          (e) Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which a Loan
Party is located, or any treaty to which such jurisdiction is a party, with
respect to payments under this Agreement shall deliver to such Loan Party (with
a copy to the Applicable Agent), at the time or times prescribed by applicable
law, such properly completed and executed documentation prescribed by applicable
law or reasonably requested by such Loan Party as will permit such payments to
be made without withholding or at a reduced rate, provided that such Foreign
Lender has received written notice from such Loan Party advising it of the
availability of such exemption or reduction and supplying all applicable
documentation.

          SECTION 2.18. Payments Generally; Pro Rata Treatment; Sharing of Set-
                        -------------------------------------------------------
offs. (a) Each Borrower shall make each payment required to be made by it
----
hereunder or under any other Loan Document (whether of principal, interest, fees
or reimbursement of LC Disbursements, or of amounts payable under Section 2.15,
2.16 or 2.17, or otherwise) prior to the time expressly required hereunder or
under such other Loan Document for such payment (or, if no
<PAGE>

                                                                              69

such time is expressly required, prior to 3:00 p.m. in the Applicable
Jurisdiction), on the date when due, in immediately available funds, without
set-off or counterclaim. Any amounts received after such time on any date may,
in the discretion of the Applicable Agent, be deemed to have been received on
the next succeeding Business Day for purposes of calculating interest thereon.
All such payments to the US Agent shall be made to it at its offices at 270 Park
Avenue, New York, New York, and all such payments to the Canadian Agent shall be
made to it at its offices at 100 King Street West, Suite 6900, Toronto M5X1A4,
Canada, except for payments to be made directly to any Issuing Bank as expressly
provided herein and except that payments pursuant to Sections 2.15, 2.16, 2.17
and 9.03 shall be made directly to the Persons entitled thereto and payments
pursuant to other Loan Documents shall be made to the Persons specified therein.
Each Facility Agent shall distribute any such payments received by it for the
account of any other Person to the appropriate recipient promptly following
receipt thereof. If any payment under any Loan Document shall be due on a day
that is not a Business Day, the date for payment shall be extended to the next
succeeding Business Day, and, in the case of any payment accruing interest,
interest thereon shall be payable for the period of such extension. All payments
of the principal of and interest on and other amounts in respect of Canadian
Term Loans and B/As, and all payments of commitment fees in respect of the
Canadian Term Commitments and of B/A acceptance fees, shall be payable in
Canadian Dollars. All other payments under each Loan Document shall be made in
US Dollars.

          (b) If at any time insufficient funds are received by and available to
a Facility Agent to pay fully all amounts of principal, unreimbursed LC
Disbursements, interest and fees then due hereunder, such funds shall be applied
ratably among the parties entitled thereto in accordance with the amounts then
due to such parties.

          (c) If any Lender shall, by exercising any right of set-off or
counterclaim or otherwise, obtain payment in respect of any principal of or
interest on its Term Loans or Revolving Loans or payment obligation in respect
of a B/A or LC Disbursement due from either Borrower resulting in such Lender
receiving payment of a greater proportion of the aggregate amount of the
principal of or interest on its Term Loans or Revolving Loans or payment
obligations in respect of B/As or LC Disbursements due to it from such Borrower
than the proportion received by any other Lender, then the Lender receiving such
greater proportion shall purchase (for cash at face value) participations in the
Revolving Loans,
<PAGE>

                                                                              70

Term Loans and payment obligations in respect of B/As and participations in LC
Disbursements of other Lenders owed by such Borrower to the extent necessary so
that the benefit of all such payments shall be shared by the Lenders ratably in
accordance with the aggregate amounts of such principal, interest and other
payment obligations owed to them; provided that (i) if any such participations
                                  --------
are purchased and all or any portion of the payment giving rise thereto is
recovered, such participations shall be rescinded and the purchase price
restored to the extent of such recovery, without interest, and (ii) the
provisions of this paragraph shall not be construed to apply to any payment made
by a Borrower pursuant to and in accordance with the express terms of this
Agreement or any payment obtained by a Lender as consideration for the
assignment of or sale of a participation in any of its Loans, claims in respect
of B/As or participations in LC Disbursements to any assignee or participant,
other than to a Borrower or any subsidiary or Affiliate thereof (as to which the
provisions of this paragraph shall apply). The Borrowers consent to the
foregoing and agree, to the extent they may effectively do so under applicable
law, that any Lender acquiring a participation pursuant to the foregoing
arrangements may exercise against the applicable Borrower rights of set-off and
counterclaim with respect to such participation as fully as if such Lender were
a direct creditor of such Borrower in the amount of such participation.

          (d) Unless the Applicable Agent shall have received notice from a
Borrower prior to the date on which any payment is due to such Agent for the
account of the Lenders or any Issuing Bank hereunder that such Borrower will not
make such payment, such Agent may assume that such Borrower has made such
payment on such date in accordance herewith and may, in reliance upon such
assumption, distribute to the Lenders or such Issuing Bank, as the case may be,
the amount due. In such event, if such Borrower has not in fact made such
payment, then each of the Lenders or such Issuing Bank, as the case may be,
severally agrees to repay to such Agent forthwith on demand the amount so
distributed to such Lender or Issuing Bank with interest thereon, for each day
from and including the date such amount is distributed to it to but excluding
the date of payment to such Agent, at a rate determined by such Agent in
accordance with banking industry rules on interbank compensation.

          (e) If any Lender shall fail to make any payment required to be made
by it hereunder, then the Facility Agents may, in their discretion
(notwithstanding any contrary provision hereof), apply any amounts thereafter
<PAGE>

                                                                              71

received by them for the account of such Lender to satisfy such Lender's
obligations under such Sections until all such unsatisfied obligations are fully
paid.

          SECTION 2.19. Mitigation Obligations; Replacement of Lenders. (a) If
                        ----------------------------------------------
any Lender requests compensation under Section 2.15, or if a Borrower is
required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to Section 2.17, then such
Lender shall use reasonable efforts to designate a different lending office for
funding or booking its Loans hereunder or to assign its rights and obligations
hereunder to another of its offices, branches or affiliates, if, in the judgment
of such Lender, such designation or assignment (i) would eliminate or reduce
amounts payable pursuant to Section 2.15 or 2.17, as the case may be, in the
future and (ii) would not subject such Lender to any unreimbursed cost or
expense and would not otherwise be disadvantageous to such Lender. The Borrowers
hereby agree to pay all reasonable costs and expenses incurred by any Lender in
connection with any such designation or assignment.

          (b) If any Lender requests compensation under Section 2.15, or if a
Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.17,
or if any Lender defaults in its obligation to fund Loans or accept and purchase
B/As hereunder, then the Company may, at its sole expense (subject to any claims
it may have against a defaulting Lender), upon notice to such Lender and the
Facility Agents, require such Lender to assign and delegate, without recourse
(in accordance with and subject to the restrictions contained in Section 9.04),
all its interests, rights and obligations under this Agreement to an assignee
that shall assume such obligations (which assignee may be another Lender, if a
Lender accepts such assignment); provided that (i) the Company shall have
                                 --------
received the prior written consent of the Facility Agents (and, if a Revolving
Commitment is being assigned, each Issuing Bank), which consent shall not
unreasonably be withheld, (ii) such Lender shall have received payment of an
amount equal to the outstanding principal of its Loans and participations in LC
Disbursements, accrued interest thereon, accrued fees and all other amounts
payable to it hereunder, from the assignee (to the extent of such outstanding
principal and accrued interest and fees) or the Borrowers (in the case of all
other amounts) and (iii) in the case of any such assignment resulting from a
claim for compensation under Section 2.15 or payments required to be made
pursuant to Section 2.17, such assignment will result
<PAGE>

                                                                              72

in a material reduction in the compensation or payments required under such
Sections. A Lender shall not be required to make any such assignment and
delegation if, prior thereto, as a result of a waiver by such Lender or
otherwise, the circumstances entitling the Company to require such assignment
and delegation cease to apply.

          SECTION 2.20. Increase in Revolving Commitments. During the period
                        ---------------------------------
beginning with the Effective Date and ending on the date that is 60 days
thereafter, the Company may, by written notice to the US Agent, executed by the
Company and one or more financial institutions (any such financial institution
referred to in this Section being called a "Prospective Revolving Lender"),
                                            ----------------------------
which may include any Lender, cause the Revolving Commitments of the Prospective
Revolving Lenders to be increased (or cause Revolving Commitments to be extended
by the Prospective Revolving Lenders, as the case may be) in an amount for each
Prospective Revolving Lender set forth in such notice, provided, however, that
                                                       -----------------
(a) the aggregate amount of the Lenders' Revolving Commitments after giving
effect to such increase shall in no event exceed US$75,000,000, (b) each
Prospective Revolving Lender, if not already a Lender hereunder, shall be
subject to the approval of the US Agent (which approval shall not be
unreasonably withheld) and (c) each Prospective Revolving Lender, if not already
a Lender hereunder, shall become a party to this Agreement by completing and
delivering to the US Agent a duly executed Accession Agreement on or prior to
the date that is 60 days after the Effective Date. Increases and new Revolving
Commitments created pursuant to this Section shall become effective (A) in the
case of Prospective Revolving Lenders already parties hereunder, on the date
specified in the notice delivered pursuant to this Section (which shall be a
date no later than the 60th day after the Effective Date) and (B) in the case of
Prospective Revolving Lenders not already parties hereunder, on the effective
date of the Accession Agreement (which shall be a date no later than the 60th
day after the Effective Date). Upon the effectiveness of any Accession Agreement
to which any Prospective Revolving Lender is a party, (i) such Prospective
Revolving Lender shall thereafter be deemed to be a party to this Agreement and
shall be entitled to all rights, benefits and privileges accorded a Lender
hereunder and subject to all obligations of a Lender hereunder and (ii) Schedule
2.01 shall be deemed to have been amended to reflect the Revolving Commitment of
the additional Lender as provided in such Accession Agreement. Upon the
effectiveness of any increase pursuant to this Section in the Revolving
Commitment of a Lender already a party hereunder, Schedule 2.01 shall be deemed
to have been amended to
<PAGE>

                                                                              73

reflect the increased Revolving Commitment of such Lender. Notwithstanding the
foregoing, no increase in the aggregate Revolving Commitments (or in the
Revolving Commitment of any Lender) shall become effective under this Section
unless, on the date of such increase, the conditions set forth in paragraphs (a)
and (b) of Section 4.02 shall be satisfied (with all references in such

proceedings, claims or disputes pending, or to the knowledge of either Borrower,

Governmental Authority, against the Company or any of its Subsidiaries or any of
their respective properties which:

          (a) purport to affect or pertain to this Agreement or any other Loan
Document, or any of the Transactions; or

          (b) could reasonably be expected to be determined adversely to the

Borrowers, nothing has occurred which would cause the loss of such
qualification. The Company and each ERISA Affiliate has made all required
contributions to any Plan subject to Section 412 of the Code, and no application
for a funding waiver or an extension of any amortization period pursuant to
Section 412 of the Code has been made with respect to any Plan.

          (b) There are no pending or, to the best knowledge of the Borrowers,
threatened claims, actions or lawsuits, or actions by any Governmental

transaction or violation of the fiduciary responsibility rules with respect to
any Plan

neither the Company nor any ERISA Affiliate has engaged in a transaction that
could be subject to Section 4069 or 4212(c) of ERISA; which, in the case of any

be expected to create a material liability to the Company and the Subsidiaries.

Liens. The Mortgaged Properties on the date of this Agreement are identified on
Schedule 3.09.

ordinary course operations, all such Environmental Permits are in good standing,

9.02), and (c) except as expressly set forth in the Loan Documents, the Agents
shall not have any duty to disclose, and shall not be liable for the failure to
disclose, any information relating to the Company or any Subsidiary that is
communicated to or obtained by it in any capacity other than its capacity as
Agent. The Agents shall not be liable for any action taken or not taken by them
with the consent or at the request of the Required Lenders (or such other number
or percentage of the Lenders as shall be necessary under the circumstances as
provided in Section 9.02) or in the absence of their own gross negligence or
wilful misconduct. The Agents shall not be deemed to have knowledge of any
Default unless and until written notice thereof is given to them by the Company
or a Lender, and the Agents shall not be responsible for or have any duty to
ascertain or inquire into (i) any statement, warranty or representation made in
or in connection with any Loan Document, (ii) the contents of any certificate,
report or other document delivered thereunder or in connection therewith, (iii)
the performance or observance of any of the covenants, agreements or other terms
or conditions set forth in any Loan Document, (iv) the validity, enforceability,
effectiveness or genuineness of any Loan Document or any other agreement,
instrument or document, or (v) the satisfaction of any condition set forth in
Article IV or elsewhere in any Loan Document, other than to confirm receipt of
items expressly required to be delivered to them.

          The Agents shall be entitled to rely upon, and shall not incur any
liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing believed by them to be genuine
and to have been signed or sent by the proper Person. The Agents also may rely
upon any statements made to them orally or by telephone and believed by them to
be made by the proper Persons, and shall not incur any liability for relying
thereon. The Agents may consult with legal counsel (who may be counsel for the
Company), independent accountants and other experts selected by them, and shall
not be liable for any action taken or not taken by them in
<PAGE>

                                                                             115

accordance with the advice of any such counsel, accountants or experts.

          The Agents may perform any of and all their duties and exercise their
rights and powers by or through any one or more sub-agents appointed by them and
selected with reasonable care. The Agents and any such sub-agent may perform any
and all its duties and exercise its rights and powers through their respective
Related Parties. The exculpatory provisions of the preceding paragraphs shall
apply to any such sub-agent and to the Related Parties of each Agent and any
such sub-agent, and shall apply to their respective activities in connection
with the syndication of the credit facilities provided for herein as well as
activities in their capacities as Agents.

          Subject to the appointment and acceptance of a successor Agent as
provided in this paragraph, any Agent may resign at any time by notifying the
Lenders, the Issuing Banks and the Borrowers. Upon any such resignation, the
Required Lenders shall have the right, in consultation with the Borrowers, to
appoint a successor. If no successor shall have been so appointed by the
Required Lenders and shall have accepted such appointment within 30 days after
the retiring Agent gives notice of its resignation, then the retiring Agent may,
on behalf of the Lenders and the Issuing Banks, appoint a successor Agent which
shall be (a) in the case of a successor to the US Agent, a bank with an office
in New York, New York, or an Affiliate of any such bank, and (b) in the case of
a successor to the Canadian Agent, a bank with an office in Toronto, Canada, or
an Affiliate of any such bank. Upon the acceptance of its appointment as an
Agent hereunder by a successor, such successor shall succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Agent,
and the retiring Agent shall be discharged from its duties and obligations
hereunder. The fees payable by the Borrowers to a successor Agent shall be the
same as those payable to its predecessor unless otherwise agreed between the
Borrowers and such successor. After an Agent's resignation hereunder, the
provisions of this Article and Section 9.03 shall continue in effect for the
benefit of such retiring Agent, its sub-agents and their respective Related
Parties in respect of any actions taken or omitted to be taken by any of them
while it was acting as Agent.

          Each Lender acknowledges that it has, independently and without
reliance upon any Agent or any other Lender and based on such documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. Each Lender also

acknowledges that it will, independently and without reliance upon any Agent or
any other Lender and based on such documents and information as it shall from
time to time deem appropriate, continue to make its own decisions in taking or
not taking action under or based upon this Agreement, any other Loan Document or
related agreement or any document furnished hereunder or thereunder.

          It is understood that the financial institutions named in the heading
of this Agreement as Syndication Agent and Documentation Agent shall have no
duties or responsibilities for the administration of this Agreement or the other
Loan Documents.

          SECTION 9.02. Waivers; Amendments. (a) No failure or delay by any
                        -------------------
Agent, any Issuing Bank or any Lender in exercising any right or power hereunder
or under any other Loan Document shall operate as a waiver thereof, nor shall
any single or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
and remedies of the Agents, the Issuing Banks and the Lenders hereunder and
under the other Loan Documents are cumulative and are not exclusive of any
rights or remedies that they would otherwise have. No waiver of any provision of
any Loan Document or consent to any departure by any Loan Party therefrom shall
in any event be effective unless the same shall be permitted by paragraph (b) of
this Section, and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. Without limiting the
generality of the foregoing, the making of a Loan, acceptance and purchase of a
B/A or issuance of a Letter of Credit shall not be construed as a waiver of any
Default, regardless of whether any Agent, any Lender or any Issuing Bank may
have had notice or knowledge of such Default at the time.

          (b)  Neither this Agreement nor any other Loan Document nor any
provision hereof or thereof may be waived, amended or modified except, in the
case of this Agreement, pursuant to an agreement or agreements in writing
entered into by the Borrowers and the Required Lenders or, in the case of any
other Loan Document, pursuant to an agreement or
<PAGE>

agreements in writing entered into by the Agents and Loan Parties that are party
thereto, in each case with the consent of the Required Lenders; provided that no
                                                                --------
such agreement shall (i) increase any Commitment of any Lender without the
written consent of such Lender, (ii) reduce the principal amount of any Loan or
the amount payable in respect of any B/A or LC Disbursement or reduce the rate
of interest thereon, or reduce any fees payable hereunder, without the written
consent of each Lender affected thereby, (iii) postpone the maturity of any
Loan, or any scheduled date of payment of the principal amount of any Term Loan
under Section 2.10, or the required date of any payment with respect to any B/A
or reimbursement of any LC Disbursement, or any date for the payment of any
interest or fees payable hereunder, or reduce the amount of, waive or excuse any
such payment, or postpone the scheduled date of expiration of any Commitment,
without the written consent of each Lender affected thereby, (iv) change Section
2.18(b) or (c) in a manner that would alter the pro rata sharing of payments
required thereby without the written consent of each Lender, (v) change any of
the provisions of this Section or the percentage set forth in the definition of
"Required Lenders" or any other provision of any Loan Document specifying the
number or percentage of Lenders (or Lenders of any Class) required to waive,
amend or modify any rights thereunder or make any determination or grant any
consent thereunder without the written consent of each Lender (or each Lender of
such Class, as the case may be), (vi) release the Company or any Subsidiary from
its obligations under a Guarantee Agreement (except as expressly provided herein
or in such Guarantee Agreement), or limit its liability under such Guarantee
Agreement, without the written consent of each Lender, (vii) release all or
substantially all of the Collateral from the Liens of the Security Documents
without the written consent of each Lender, or (viii) change any provisions of
any Loan Document in a manner that by its terms adversely affects the rights in
respect of payments due to Lenders holding Loans of any Class differently than
those due to Lenders holding Loans of any other Class without the written
consent of Lenders holding a majority in interest of the outstanding Loans and
unused Commitments of each Class adversely affected or not equally benefitted by
such change; provided further that (A) no such agreement shall amend, modify or
             ----------------
otherwise affect the rights or duties of any Agent or any Issuing Bank without
the prior written consent of such Agent or such Issuing Bank, as the case may
be, and (B) any waiver, amendment or modification of this Agreement that by its
terms affects the rights or duties under this Agreement of the Revolving Lenders
(but not the US Term Lenders or Canadian Term Lenders), the US Term Lenders (but
not the Revolving Lenders or the Canadian Term
<PAGE>

                                                                             119

Lenders) or the Canadian Term Lenders (but not the Revolving Lenders or the US
Term Lenders) may be effected by an agreement or agreements in writing entered
into by the Borrowers and requisite percentage in interest of the affected Class
of Lenders that would be required to consent thereto under this Section if such
Class of Lenders were the only Class of Lenders hereunder at the time.
Notwithstanding the foregoing, any provision of this Agreement may be amended by
an agreement in writing entered into by the Borrowers, the Required Lenders and
the Facility Agents (and, if their rights or obligations are affected thereby,
the Issuing Banks) if (i) by the terms of such agreement the Commitment of each
Lender not consenting to the amendment provided for therein shall terminate upon
the effectiveness of such amendment and (ii) at the time such amendment becomes
effective, each Lender not consenting thereto receives payment in full of the
principal of and interest accrued on each Loan made by it and all other amounts
owing to it or accrued for its account under this Agreement.

          SECTION 9.03. Expenses; Indemnity; Damage Waiver. (a) The Borrowers
                        ----------------------------------
shall pay (i) all reasonable out-of-pocket expenses incurred by the Agents and
their Affiliates, including the reasonable fees, charges and disbursements of
counsel for the Agents, in connection with the syndication of the credit
facilities provided for herein, the preparation and administration of the Loan
Documents or any amendments, modifications or waivers of the provisions thereof
(whether or not the transactions contemplated hereby or thereby shall be
consummated), (ii) all reasonable out-of-pocket expenses incurred by any Issuing
Bank in connection with the issuance, amendment, renewal or extension of any
Letter of Credit or any demand for payment thereunder and (iii) all reasonable
out-of-pocket expenses incurred by any Agent, any Issuing Bank or any Lender,
including the reasonable fees, charges and disbursements of any counsel for any
Agent, any Issuing Bank or any Lender, in connection with the enforcement or
protection of its rights in connection with the Loan Documents, including its
rights under this Section, or in connection with the Loans made, the B/As
accepted and purchased or Letters of Credit issued hereunder, including all such
reasonable out-of-pocket expenses incurred during any workout, restructuring or
negotiations in respect of such Loans or Letters of Credit.

          (b)  The Borrowers shall indemnify the Agents, each Issuing Bank and
each Lender, and each Related Party of any of the foregoing Persons (each such
Person being called an "Indemnitee") against, and hold each Indemnitee harmless
                        ----------

from, any and all losses, claims, damages, liabilities and related expenses,
including the reasonable fees, charges and disbursements of any counsel for any
Indemnitee, incurred by or asserted against any Indemnitee arising out of, in
connection with or as a result of (i) the execution or delivery of any Loan
Document or any other agreement or instrument contemplated hereby, the
performance by the parties to the Loan Documents of their respective obligations
thereunder or the consummation of the Transactions, (ii) any Loan, B/A or Letter
of Credit or the use of the proceeds therefrom (including any refusal by the
applicable Issuing Bank to honor a demand for payment under a Letter of Credit
if the documents presented in connection with such demand do not strictly comply
with the terms of such Letter of Credit), (iii) any actual or alleged presence
or release of Hazardous Materials on or from any property currently or formerly
owned or operated by the Company or any of its Subsidiaries, or any
Environmental Claim related in any way to the Company or any of its
Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation
or proceeding relating to any of the foregoing, whether based on contract, tort
or any other theory and regardless of whether any Indemnitee is a party thereto;
provided that such indemnity shall not, as to any Indemnitee, be available to
--------
the extent that such losses, claims, damages, liabilities or related expenses
have resulted from the gross negligence or wilful misconduct of such Indemnitee.

          (c)  To the extent that the Borrowers fail to pay any amount required
to be paid by them to any Agent or any Issuing Bank under paragraph (a) or (b)
of this Section, each Lender severally agrees to pay to such Agent or such
Issuing Bank, as the case may be, such Lender's pro rata share (determined as of
the time that the applicable unreimbursed expense or indemnity payment is
sought) of such unpaid amount; provided that the unreimbursed expense or
                               --------
indemnified loss, claim, damage, liability or related expense, as the case may
be, was incurred by or asserted against such Agent or such Issuing Bank in its
capacity as such. For purposes hereof, a Lender's "pro rata share" shall be
determined based upon its share of the sum of the total Revolving Exposures,
outstanding Term Loans and B/As and unused Commitments at the time.

          (d)  To the extent permitted by applicable law, neither Borrower shall
assert, and each hereby waives, any claim against any Indemnitee, on any theory
of liability, for special, indirect, consequential or punitive damages (as
opposed to direct or actual damages) arising out of, in connection with or as a
result of this Agreement or any

agreement or instrument contemplated hereby, the Transactions, any Loan or
Letter of Credit or the use of the proceeds thereof.

          (e)  All amounts due under this Section shall be payable promptly
after written demand therefor.

          SECTION 9.04. Successors and Assigns. (a) The provisions of this
                        ----------------------
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns permitted hereby (including any
Affiliate of any Issuing Bank that issues any Letter of Credit), except that the
Borrowers may not assign or otherwise transfer any of their rights or
obligations hereunder without the prior written consent of each Lender (and any
attempted assignment or transfer by a Borrower without such consent shall be
null and void). Nothing in this Agreement, expressed or implied, shall be
construed to confer upon any Person (other than the parties hereto, their
respective successors and assigns permitted hereby (including any Affiliate of
any Issuing Bank that issues any Letter of Credit) and, to the extent expressly
contemplated hereby, the Related Parties of each of the Agents, the Issuing
Banks and the Lenders) any legal or equitable right, remedy or claim under or by
reason of this Agreement.

          (b) Any Lender may assign to one or more assignees all or a portion of
its rights and obligations under this Agreement (including all or a portion of
its Commitments and the Loans and other amounts at the time owing to it);
provided that (i) except in the case of an assignment to a Lender or an
--------
Affiliate of a Lender, each of the Company and the US Agent (and, in the case of
an assignment of all or a portion of a Revolving Commitment or any Lender's
obligations in respect of its LC Exposure, the Issuing Banks) must give their
prior written consent to such assignment (which consent shall not be
unreasonably withheld), (ii) except in the case of an assignment to a Lender or
an Affiliate of a Lender or an assignment of the entire remaining amount of the
assigning Lender's Commitment or Loans, the amount of the Commitment or Loans of
the assigning Lender subject to each such assignment (determined as of the date
the Assignment and Acceptance with respect to such assignment is delivered to
the Administrative Agent) shall not be less than US$5,000,000 unless each of the
Company and the US Agent otherwise consent, (iii) each partial assignment shall
be made as an assignment of a proportionate part of all the assigning Lender's
rights and obligations under this Agreement, except that this clause (iii) shall
not be construed to prohibit the assignment of a proportionate part of all the
assignment Lender's rights and
<PAGE>

                                                                             122

obligations in respect of one Class of Commitments or Loans, (iv) the assignor
and assignee party to each assignment shall execute and deliver to the US Agent
an Assignment and Acceptance, together with a processing and recordation fee of
US$3,500, and (v) the assignee, if it shall not be a Lender, shall deliver to
the US Agent an Administrative Questionnaire; and provided further that any
                                                  -------- -------
consent of the Company otherwise required under this paragraph shall not be
required if an Event of Default has occurred and is continuing. Subject to
acceptance and recording thereof pursuant to paragraph (d) of this Section, from
and after the effective date specified in each Assignment and Acceptance the
assignee thereunder shall be a party hereto and, to the extent of the interest
assigned by such Assignment and Acceptance, have the rights and obligations of a
Lender under this Agreement, and the assigning Lender thereunder shall, to the
extent of the interest assigned by such Assignment and Acceptance, be released
from its obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto but shall continue
to be entitled to the benefits of Sections 2.15, 2.16, 2.17 and 9.03). Any
assignment or transfer by a Lender of rights or obligations under this Agreement
that does not comply with this paragraph shall be treated for purposes of this
Agreement as a sale by such Lender of a participation in such rights and
obligations in accordance with paragraph (e) of this Section.

          (c)  The US Agent, acting for this purpose as an agent of the
Borrowers, shall maintain at one of its offices in The City of New York a copy
of each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitment of,
and principal amount of the Loans and LC Disbursements owing to, each Lender
pursuant to the terms hereof from time to time (the "Register"). The entries in
                                                     --------
the Register shall be conclusive, and the Borrowers, the US Agent, the Issuing
Banks and the Lenders may treat each Person whose name is recorded in the
Register pursuant to the terms hereof as a Lender hereunder for all purposes of
this Agreement, notwithstanding notice to the contrary. The Register shall be
available for inspection by the Borrowers, the Issuing Banks and any Lender, at
any reasonable time and from time to time upon reasonable prior notice.

          (d)  Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee, the assignee's completed
Administrative Questionnaire (unless the assignee shall already be a Lender
<PAGE>

                                                                             123

hereunder), the processing and recordation fee referred to in paragraph (b) of
this Section and any written consent to such assignment required by paragraph
(b) of this Section, the US Agent shall accept such Assignment and Acceptance
and record the information contained therein in the Register. No assignment
shall be effective for purposes of this Agreement unless it has been recorded in
the Register as provided in this paragraph.

          (e)  Any Lender may, without the consent of either Borrower, the US
Agent or the Issuing Banks, sell participations to one or more banks or other
entities (a "Participant") in all or a portion of such Lender's rights and/or
             -----------
obligations under this Agreement (including all or a portion of its Commitment
and the Loans owing to it); provided that (i) such Lender's obligations under
                            --------
this Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations
and (iii) the Borrowers, the Agents, the Issuing Banks and the other Lenders
shall continue to deal solely and directly with such Lender in connection with
such Lender's rights and obligations under this Agreement. Any agreement or
instrument pursuant to which a Lender sells such a participation shall provide
that such Lender shall retain the sole right to enforce the Loan Documents and
to approve any amendment, modification or waiver of any provision of the Loan
Documents; provided that such agreement or instrument may provide that such
           --------
Lender will not, without the consent of the Participant, agree to any amendment,
modification or waiver described in the first proviso to Section 9.02(b) that
adversely affects such Participant. Subject to paragraph (f) of this Section,
the Borrowers agree that each Participant shall be entitled to the benefits of
Sections 2.15, 2.16 and 2.17 to the same extent as if it were a Lender and had
acquired its interest by assignment pursuant to paragraph (b) of this Section.
To the extent permitted by law, each Participant also shall be entitled to the
benefits of Section 9.08 as though it were a Lender, provided such Participant
agrees to be subject to Section 2.18(c) as though it were a Lender.

          (f)  A Participant shall not be entitled to receive any greater
payment under Section 2.15 or 2.17 than the applicable Lender would have been
entitled to receive with respect to the participation sold to such Participant,
unless the sale of the participation to such Participant is made with the
Borrower's prior written consent. A Participant that would be a Foreign Lender
if it were a Lender shall not be entitled to the benefits of Section 2.17 unless
the Company is notified of the participation sold to such Participant and such
Participant agrees, for the
<PAGE>

                                                                             124

benefit of the Borrowers, to comply with Section 2.17(e) as though it were a
Lender.

          (g)  Any Lender may at any time pledge or assign a security interest
in all or any portion of its rights under this Agreement to secure obligations
of such Lender, including any pledge or assignment to secure obligations to a
Federal Reserve Bank, and this Section shall not apply to any such pledge or
assignment of a security interest; provided that no such pledge or assignment of
                                   --------
a security interest shall release a Lender from any of its obligations hereunder
or substitute any such pledgee or assignee for such Lender as a party hereto.

          SECTION 9.05. Survival. All covenants, agreements, representations and
                        --------
warranties made by the Loan Parties in the Loan Documents and in the
certificates or other instruments delivered in connection with or pursuant to
this Agreement or any other Loan Document shall be considered to have been
relied upon by the other parties hereto and shall survive the execution and
delivery of the Loan Documents and the making of any Loans and issuance of any
Letters of Credit, regardless of any investigation made by any such other party
or on its behalf and notwithstanding that any Agent, any Issuing Bank or any
Lender may have had notice or knowledge of any Default or incorrect
representation or warranty at the time any credit is extended hereunder, and
shall continue in full force and effect as long as the principal of or any
accrued interest on any Loan or any fee or any other amount payable under this
Agreement is outstanding and unpaid or any Letter of Credit is outstanding and
so long as the Commitments have not expired or terminated. The provisions of
Sections 2.15, 2.16, 2.17 and 9.03 and Article VIII shall survive and remain in
full force and effect regardless of the consummation of the transactions
contemplated hereby, the repayment of the Loans, the expiration or termination

          SECTION 9.06. Counterparts; Integration; Effectiveness. This Agreement
                        ----------------------------------------
may be executed in counterparts (and by different parties hereto on different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Agreement, the other
Loan Documents and any separate letter agreements with respect to fees payable
to the Agents constitute the entire contract among the parties relating to the
subject matter hereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject

                                                                             125

matter hereof. Except as provided in Section 4.01, this Agreement shall become
effective when it shall have been executed by the Agents and when the US Agent
shall have received counterparts hereof which, when taken together, bear the
signatures of each of the other parties hereto, and thereafter shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns. Delivery of an executed counterpart of a signature page
of this Agreement by telecopy shall be effective as delivery of a manually
executed counterpart of this Agreement.

          SECTION 9.07. Severability. Any provision of this Agreement held to be
                        ------------
invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

          SECTION 9.08. Right of Setoff. If an Event of Default shall have
                        ---------------
occurred and be continuing, each Lender and each of its Affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other obligations at any time
owing by such Lender or Affiliate to or for the credit or the account of either
Borrower against any of and all the obligations of such Borrower now or
hereafter existing under this Agreement held by such Lender, irrespective of
whether or not such Lender shall have made any demand under this Agreement and
although such obligations may be unmatured. The rights of each Lender under this
Section are in addition to other rights and remedies (including other rights of
setoff) which such Lender may have. Each Lender agrees to notify, as promptly as
practicable under the circumstances, the Borrowers and the Facility Agents after
it exercises any right of setoff and application under this Section (it being
agreed that the failure to provide such notice shall in no way affect any
Lender's setoff rights).

District of New York, and any appellate court from any thereof, in any action or
proceeding arising out of or relating to any Loan Document, or for recognition
or enforcement of any judgment, and each of the parties hereto hereby
irrevocably and unconditionally agrees that all claims in respect of any such

the extent permitted by law, in such Federal court. Each of the parties hereto
agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Agreement or any other Loan
Document shall affect any right that any Agent, any Issuing Bank or any Lender
may otherwise have to bring any action or proceeding relating to this Agreement
or any other Loan Document against either Borrower or its properties in the
courts of any jurisdiction.

          (c)  Each Borrower hereby irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection which it
may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement or any other Loan
Document in any court referred to in paragraph (b) of this Section. Each of the
parties hereto hereby irrevocably waives, to the fullest extent permitted by
law, the defense of an inconvenient forum to the maintenance of such action or
proceeding in any such court.

          (d)  Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 9.01. Nothing in this

PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY
OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B)

          SECTION 9.13. Interest Rate Limitation. Notwithstanding anything
                        ------------------------
herein to the contrary, if at any time the interest rate applicable to any Loan,

on such Loan under applicable law (collectively the "Charges"), shall exceed the

any Subsidiary Guarantor or any Collateral permitted to be sold under the terms

thereof will comply with the terms of this Agreement, the applicable Collateral
Agent, if satisfied that the applicable certificate is correct, shall, without
the consent of any Lender, execute and deliver all such instruments, releases,
financing statements or other agreements, and take all such further actions, as
shall be necessary to effectuate the release of such Subsidiary Guarantor or
such Collateral.

liability that would reasonably be expected to have a Material Adverse Effect,
and the Company has no reason to believe it may become subject to any clean up
liability that would reasonably be expected to have a Material Adverse Effect,
under any federal, state or local environmental law, rule or regulation.

          SECTION 2.13.  Disclosure.
                         ----------

          (a)  Neither this Agreement nor any of the schedules, attachments,
written statements, documents, certificates or other items prepared or supplied
to the Purchasers by or on behalf of the Company with respect to the
transactions contemplated hereby (collectively, the "Materials") contain any
untrue statement of material fact or omit a material fact necessary to make each
statement contained herein or therein not misleading. There is no fact which the
Company has not disclosed to the Purchasers in writing and of which any of its
officers, directors or executive employees is aware and which has had or might
reasonably be anticipated to have a material adverse effect upon the existing or
expected financial condition, operating results, assets, customer or supplier
relations, employee relations or business prospects of the Company and its
Subsidiaries taken as a whole.

          (b)  Except as and to the extent specifically set forth in this
Agreement (including, with respect to any Materials, the representations set
forth in paragraph (a) hereof), neither the Company nor any Subsidiary makes any
representation or warranty of any kind or nature with respect to the matters
contemplated hereby.

                                     III.

true and correct in all material respects as of the dates and for the period

     principles consistently applied, or fair market value, determined by the

     transaction or series of related transactions (other than sales of

                         ---------------------
any Shares, the Company shall, and shall cause each Subsidiary to:

          (i)   comply with all applicable laws, rules and regulations of all
     governmental authorities, the violation of which would reasonably be
     expected to have a Material Adverse Effect, and pay and discharge when

     of the Purchasers.

          SECTION 4.05.  Current Public Information.  At all times after the
                         --------------------------
Company has filed a registration statement with the Securities and Exchange
Commission pursuant to the requirements of either the Securities Act or the
Securities Exchange Act of 1934 as amended (the "Securities Exchange Act"), the
Company shall file all reports required to be filed by it under the Securities
Act and the Securities Exchange Act and the rules and regulations adopted by the
Securities and Exchange Commission thereunder and shall take such further action
as any holder or holders of the Securities may reasonably request, all to the
extent required to enable such holders to sell the Securities pursuant to (i)
Rule 144 adopted by the Securities and Exchange Commission under the Securities
Act (as such rule may be amended from time to time) or any similar rule or
regulation hereafter adopted by the Securities and Exchange Commission or (ii) a
registration statement on Form S-2 or S-3 or any similar registration form

                         -----------------------------
amend, modify or waive any provision of any Management Agreement without the

          SECTION 4.07.  Limited Preemptive Rights.
                         -------------------------

          (i)   Except for the issuance of shares of Common Stock (a) pursuant
     to the Other Senior Management Agreements, (b) as consideration for
     acquisitions, (c) upon the exercise of stock options granted pursuant to a
     stock option or other benefit plan or arrangement approved by the Board of

                                       14
<PAGE>

     of warrants approved by the Board of Directors of the Company or (e)
     pursuant to a public offering registered under the Securities Act, if the
     Company at any time after the Closing authorizes the issuance or sale of
     any shares of Common Stock or any securities containing options or rights
     to acquire any shares of Common Stock (other than as a dividend on the
     outstanding Common Stock), the Company shall first offer to sell to each
     holder of Shares (without duplication) a portion of such stock or
     securities equal to the quotient determined by dividing (1) the number of
     shares of Shares held by such holder by (2) the total number of shares of
     Common Stock outstanding on a fully diluted basis immediately prior to such
     issuance; provided, however, that if two or more securities shall be
     proposed to be sold as a "unit" in such issuance, any such election must
     relate to such unit of securities. Each holder of Shares shall be entitled
     to purchase all or any portion of such stock or securities at the most
     favorable price and on the most favorable terms as such stock or securities
     are to be offered to any other persons.

          (ii)  In order to exercise its purchase rights hereunder a holder of
     Shares must within 15 days after receipt of written notice from the Company
     describing in reasonable detail the stock or securities being offered, the
     purchase price thereof, the payment terms and such holder's percentage
     allotment deliver a written notice to the Company describing its election
     hereunder. If all of the stock and securities offered to the holders of
     Shares is not fully subscribed by such holders, the remaining stock and
     securities shall be reoffered by the Company to the holders purchasing
     their full allotment upon the terms set forth in this paragraph, except
     that such holders must exercise their purchase rights within five days
     after receipt of such reoffer.

          (iii) Upon the expiration of the offering periods described above, the
     Company shall be entitled to sell such stock or securities which the
     holders of Shares have not elected to purchase during the 90 days following
     such expiration on terms and conditions no more favorable to the purchasers
     thereof than those offered to such holders. Any stock or securities offered
     or sold by the Company after such 90-day period must be reoffered to the
     holders of Shares pursuant to the terms of this paragraph.

          (iv)  Nothing contained in this Section 4.07 shall be deemed to amend,
     modify or limit in any way the restrictions on the issuance of shares of
     stock set forth in Section 4.03 hereof or elsewhere in this Agreement, in
     the Stockholders Agreement or in any other agreement to which the Company
     is bound.

          SECTION 4.08.  Public Disclosures.  The Company shall not, nor shall
                         ------------------
it permit any Subsidiary to, disclose any Purchaser's name or identity as an
investor in the Company in any press release or other public announcement or in
any document or material filed with any governmental entity, without the prior
written consent of such Purchaser, unless such disclosure is required by
applicable law or governmental regulations or by order of a court of competent
jurisdiction, in which case prior to making such disclosure the Company shall
give written notice to such Purchaser describing in reasonable detail the
proposed content of such disclosure and shall permit such Purchaser to review
and comment upon the form and substance of such disclosure.

          SECTION 4.09.  Unrelated Business Taxable Income.  The Company shall
                         ---------------------------------
not engage in any action which is reasonably likely to cause any Purchaser or
any of its limited partners which are exempt from income taxation under Section
501(a) of the IRC and, if applicable, any pension plan that any such trust may
be a part of, to recognize unrelated business taxable income as defined in
Section 512 and Section 514 of the IRC.

          SECTION 4.10.  Hart-Scott-Rodino Compliance.  In connection with any
                         ----------------------------
transaction in which the Company is involved which is required to be reported
under the HSR Act, the Company shall prepare and file all documents with the
Federal Trade Commission ("FTC") and the United States Department of Justice
("DOJ") which may be required to comply with the HSR Act, and shall promptly
furnish all materials thereafter requested by any of the regulatory agencies
having jurisdiction over such filings, in connection with the transactions
contemplated thereby.  The Company shall take all reasonable actions and shall
file and use reasonable best efforts to have declared effective or approved all
documents and notifications with any governmental or regulatory bodies, as may
be necessary or may reasonably be requested under federal antitrust laws for the
consummation of the subject transaction.  Without limiting the generality of the
foregoing, the Company, WCAS VII and GTCR Fund V promptly after the execution
and delivery of this Agreement shall prepare and file all documents with the FTC
and the DOJ to comply with the HSR Act with respect to the purchase of the
Shares by WCAS VII and GTCR Fund V.  It is understood that the Shares acquired
hereunder by WCAS VII and GTCR Fund V will not entitle the holder thereof to any
voting rights and that the Company shall cause all voting restrictions on said
Shares to be removed concurrently with the expiration or termination of all
applicable waiting periods under the HSR Act in accordance with the Certificate
of Amendment.

          SECTION 4.11.  Conduct of the Company's Business.  The Company
                         ---------------------------------
covenants and agrees that, between the date hereof and the Closing Date, unless
WCAS VII and GTCR shall otherwise consent in writing, the Company shall not (i)
issue, sell, pledge or dispose of, or agree to issue, sell, pledge or dispose
of, any shares of, or securities convertible or exchangeable for, or any
options, warrants or rights of any kind to acquire any shares of, its capital
stock of any class, except as provided herein; (ii) acquire (by merger,
consolidation or acquisition of stock or assets) any corporation, partnership or
other business organization or division thereof (except an existing wholly-owned
subsidiary) or any material amount of assets; (iii) incur or guarantee any
indebtedness for borrowed money or refinance any such indebtedness or issue or
sell any debt securities; (iv) enter into or modify any material contract,
lease, agreement or commitment, or permit or perform any act that would cause a
material breach of any such contract, lease, agreement or commitment; (v) make
any loans, advances or capital contributions to or investments in, any other
person; or (vi) violate or fail to perform in any material respect any
obligation imposed upon the Company or any of its subsidiaries by any applicable
laws, orders, decrees, ordinances, government rules or regulations.

          SECTION 4.12.  Further Assurances.  Subject to the terms and
                         ------------------
conditions herein provided, each of the parties hereto agrees to use its
reasonable best efforts to take, or cause to be taken, all action and to do, or
cause to be done, all things necessary, proper or advisable to consummate and
make effective as promptly as practicable the transactions contemplated by this
Agreement, the Ancillary Agreements and the Merger Agreement, including, without
limitation,

                                       16

using all reasonable efforts to obtain all necessary waivers, consents and
approvals and to effect all necessary registrations and filings.

          SECTION 4.13.  Transfer of Restricted Securities.
                         ---------------------------------

          (a)  Restricted Securities are transferable only pursuant to (i)
public offerings registered under the Securities Act, (ii) Rule 144 or Rule 144A
of the Securities and Exchange Commission (or any similar rule or rules then in
force) if such rule or rules are available and (iii) subject to the conditions
specified in subparagraph (b) below, any other legally available means of
transfer.

          (b)  In connection with the transfer of any Restricted Securities
(other than a transfer described in Section 4.1 3(a)(i) or (ii) above), the
holder thereof shall deliver written notice to the Company describing in
reasonable detail the transfer or proposed transfer, together with an opinion of
Reboul, MacMurray, Hewitt, Maynard & Kristol or Kirkland & Ellis or other
counsel which (to the Company's reasonable satisfaction) is knowledgeable in
securities law matters to the effect that such transfer of Restricted Securities
may be effected without registration of such Restricted Securities under the
Securities Act. In addition, if the holder of the Restricted Securities delivers
to the Company an opinion of Reboul, MacMurray, Hewitt, Maynard & Kristol or
Kirkland & Ellis or such other counsel that no subsequent transfer of such
Restricted Securities shall require registration under the Securities Act, the
Company shall promptly upon such contemplated transfer deliver new certificates
for such Restricted Securities which do not bear the Securities Act legend set
