Multi-Currency Loans or the Term Loans of one Type into Loans of the other Type
(as provided in Section 3.02(a) hereof) or continue Eurocurrency Loans for
subsequent Interest Periods. Unless otherwise provided herein, all
Multi-Currency Loans and all US$-Canadian Loans, other than Dollar-denominated
Multi-Currency Loans and Dollar-denominated US$-Canadian Loans, shall be made,
maintained and continued as Eurocurrency Loans.

          (b) The Loans outstanding under the Existing Credit Agreement on the
Effective Date other than the Tranche A Term Loans and the Tranche B Term Loans
thereunder (which shall be prepaid in full on the Effective Date) shall continue
to be outstanding and shall be continued under this Agreement (such Loans to be
continuing, the "EXISTING LOANS").

          (c) The Swingline Lender agrees to make a portion of the credit
otherwise available to the Company under the US$ Commitments from time to time
during the Commitment Period by making swing line loans ("SWINGLINE LOANS") to
the Company in an aggregate principal amount at any one time outstanding up to
but not exceeding the amount of the Swingline Commitment (notwithstanding that
the Swingline Loans outstanding at any time, when aggregated with the Swingline
Lender's other outstanding Revolving Loans, may exceed the Swingline Commitment
then in effect), PROVIDED that in no event shall the aggregate outstanding
principal amount of all US$ Loans and Swingline Loans, together with the
aggregate amount of all Letter of Credit Liabilities under the US$ Commitments
outstanding, exceed the aggregate amount of the US$ Commitments as in effect
from time to time. During the Commitment Period, the Company may use the
Swingline Commitment by borrowing, repaying and reborrowing, all in accordance
with the terms and conditions hereof. Swingline Loans shall be ABR Loans only.
For purposes of calculating the commitment fee payable in respect of the US$
Commitments under Section 2.03, the Swingline Loans shall not be treated as
usage of the US$ Commitments. Swingline Loans shall be Dollar-denominated Loans
only.

          2.02. REDUCTIONS OF COMMITMENTS.

          (a) MANDATORY. The US$ Commitments, the US$-Canadian Commitments and
Multi-Currency Commitments shall terminate on the Commitment Termination Date.
In addition, the US$ Commitments, the US$-Canadian Commitments and
Multi-Currency Commitments shall be reduced as provided in Section 3.02(c).

          (b) OPTIONAL. The Company shall have the right to terminate or reduce
the unused US$ Commitments, US$-Canadian Commitments and Multi-Currency
Commitments (for which purpose use of the US$ Commitments and Multi-Currency
Commitments shall be deemed to include the aggregate amount of Letter of Credit
Liabilities under the US$ Commitment or the Multi-Currency Commitment, as the
case may be) at any time or from time to time, provided that

<Page>

                                                                              32

(i) the Company shall give notice of each such termination or reduction to the
Administrative Agent as provided in Section 5.05 hereof and (ii) each partial
reduction shall be in an aggregate amount at least equal to $1,000,000.

          (c) NO REINSTATEMENT. US$ Commitments, US$-Canadian Commitments and
Multi-Currency Commitments once terminated or reduced may not be reinstated.

          2.03. FEES. The Company shall pay to the Administrative Agent for the
account of each US$ Lender, US$-Canadian Lender or Multi-Currency Lender
commitment fees in Dollars on the daily average unused amount of such Lender's
US$ Commitment, US$-Canadian Commitment or Multi-Currency Commitment, as the
case may be, (for which purpose, (i) the aggregate amount of any Letter of
Credit Liabilities under the US$ Commitments or the Multi-Currency Commitments
shall be deemed to be a PRO RATA (based on the US$ Commitments or the
Multi-Currency Commitments, as the case may be) use of each Lender's US$
Commitment or Multi-Currency Commitment, as the case may be, and (ii) the daily
average amount of each US$-Canadian Lender's US$-Canadian Commitment shall be
determined after giving effect to the allocation of the Canadian Commitments and
the US$-Canadian Commitments pursuant to subsection 2.6 of Annex A hereto) for
the period from the Effective Date to and including the earlier of the date the
Revolving Commitments are terminated and the Commitment Termination Date, at a
rate per annum equal to the Applicable Commitment Fee Rate in effect from time
to time. Accrued commitment fees under this Section 2.03 shall be payable on the
Quarterly Dates and on the earlier of the date the Revolving Commitments are
terminated and the Commitment Termination Date. The Company shall pay to
JPMorgan Chase Bank on the Effective Date syndication, agency and additional
commitment fees in the amounts heretofore mutually agreed in writing. The
Company shall pay to the Administrative Agent on the Effective Date and on each
anniversary thereof, so long as any of the Commitments are in effect and until
payment in full of all Loans hereunder, all interest thereon and all other
amounts payable hereunder, an annual agency fee in the amount heretofore
mutually agreed in writing.

          2.04. LENDING OFFICES. The Loans of each Type made by each Lender
shall be made and maintained at such Lender's Applicable Lending Office for
Loans of such Type.

          2.05. SEVERAL OBLIGATIONS: REMEDIES INDEPENDENT. The failure of any
Lender to make any Loan to be made by it on the date specified therefor shall
not relieve any other Lender of its obligation to make its Loan on such date,
but neither the Administrative Agent nor any Lender shall be responsible for the
failure of any other Lender to make a Loan to be made by such other Lender. The
amounts payable by the Borrowers at any time hereunder and under the Notes to
each Lender shall be a separate and independent debt and each Lender shall be
entitled to protect and enforce its rights arising out of this Agreement and the
Notes, and it shall not be necessary for any other Lender or the Administrative
Agent to consent to, or be joined as an additional party in, any proceedings for
such purposes.

          2.06. NOTES. The Loans made by each Lender under its US$ Commitment,
US$-Canadian Commitment, Multi-Currency Commitment or Term Commitment shall be
evidenced by a single promissory note of the relevant Borrower (each, a "NOTE")
in substantially the form of Exhibit A-1 (in the case of Revolving Loans) or
Exhibit A-2 (in the case of Term Loans) hereto, dated the Effective Date,
payable to such Lender in a principal amount equal to

<Page>

                                                                              33

such Commitment as in effect on the Effective Date and otherwise duly completed.
Each Lender is hereby authorized by the Company to endorse on the schedule (or a
continuation thereof) attached to each Note of such Lender, to the extent
applicable, the date, amount and Type of and the Interest Period (if any) for
each Loan made by such Lender to any Borrower under the relevant Commitment, and
the date and amount of each payment or prepayment of principal of such Loan
received by such Lender, provided that any failure by such Lender to make any
such endorsement shall not affect the obligations of the relevant Borrower under
such Note or hereunder in respect of such Loan.

          2.07. USE OF PROCEEDS. The proceeds of the Loans shall be used in part
to prepay existing term loans and for the general corporate purposes of the
Company and its Subsidiaries, including, without limitation, the making of
Permitted Acquisitions and capital expenditures and the refinancing of existing
Indebtedness of the Company and its Subsidiaries. The proceeds of the Term Loans
shall be used on the Effective Date to prepay existing term loans. Neither the
Administrative Agent nor any Lender shall have any responsibility as to the use
of any of the proceeds of any of the Loans or Letters of Credit.

          2.08. LETTERS OF CREDIT. Subject to the terms and conditions of this
Agreement, the US$ Commitments and the Multi-Currency Commitments may be
utilized, upon the request of any Borrower, in addition to the Loans provided
for by Section 2.01 hereof or in Annex A hereto, as the case may be, for the
issuance by the Issuing Bank of standby letters of credit (collectively with the
Existing Letters of Credit, "LETTERS OF CREDIT") for the account of the relevant
Borrower or, in the event that the Borrower is the Company, for the account of
such of its Subsidiaries as the Company may specify, PROVIDED that in no event
shall (i) the aggregate amount of all Letter of Credit Liabilities under the US$
Commitments or the Multi-Currency Commitments, together with the aggregate
outstanding principal amount of the US$ Loans or the Multi-Currency Loans, as
the case may be, exceed the aggregate amount of the US$ Commitments or the
Multi-Currency Commitments, as the case may be, as in effect from time to time,
(ii) the aggregate outstanding amount of all Letter of Credit Liabilities under
the US$ Commitments and the Multi-Currency Commitments exceed $75,000,000 and
(iii) the expiration date of any Letter of Credit extend beyond the earlier of
the Commitment Termination Date and the date one year following the issuance of
such Letter of Credit (provided that any Letter of Credit with a one-year tenor
may provide for the renewal thereof for additional one-year periods, which
periods shall in any event not extend beyond the Commitment Termination Date).
On the Effective Date, all Existing Letters of Credit shall automatically,
without any action on the part of any Person, be deemed to be Letters of Credit
issued and outstanding hereunder (with the Existing Letters of Credit
denominated in Dollars being deemed to be issued under the US$ Commitments and
the Existing Letters of Credit denominated in other currencies being deemed to
be issued under the Multi-Currency Commitments).

          The following additional provisions shall apply to Letters of Credit:

          (a) Each Borrower shall give the Administrative Agent (or if the
     Letter of Credit is to be issued under the Multi-Currency Commitments, the
     Multi-Currency Payment Agent) at least three Business Days' irrevocable
     prior notice (effective upon receipt) specifying the Business Day (which
     shall be no later than 5 days preceding the Commitment Termination Date) on
     which each Letter of Credit is to be issued and the

<Page>

                                                                              34

     account party or parties therefor and describing in reasonable detail the
     proposed terms of such Letter of Credit (including the beneficiary thereof)
     and the nature of the transactions or obligations proposed to be supported
     thereby. Any Letter of Credit to be issued in a currency other than Dollars
     shall be issued under the Multi-Currency Commitments. Upon receipt of any
     such notice, the Administrative Agent or the Multi-Currency Payment Agent,
     as the case may be, shall advise the Issuing Bank of the contents thereof.

          (b) On each day during the period commencing with the issuance by the
     Issuing Bank of any Letter of Credit and until such Letter of Credit shall
     have expired or been terminated, the US$ Commitment or Multi-Currency
     Commitment of each Lender shall be deemed to be utilized for all purposes
     of this Agreement in an amount equal to such Lender's US$ Commitment
     Percentage or Multi-Currency Commitment Percentage, as the case may be, of
     the then undrawn stated amount of such Letter of Credit. Each Lender (other
     than the Issuing Bank) agrees that, upon the issuance of any Letter of
     Credit hereunder, it shall automatically acquire a participation in the
     Issuing Bank's rights and obligations under such Letter of Credit in an
     amount equal to such Lender's US$ Commitment Percentage or Multi-Currency
     Commitment Percentage, as the case may be, of such rights and obligations,
     and each Lender (other than the Issuing Bank) thereby shall automatically
     absolutely, unconditionally and irrevocably assume, as primary obligor and
     not as surety, and be unconditionally obligated to the Issuing Bank to pay
     and discharge when due, its US$ Commitment Percentage or Multi-Currency
     Commitment Percentage of the Issuing Bank's obligation to pay drawings
     under such Letter of Credit.

          (c) Upon receipt from the beneficiary of any Letter of Credit of any
     demand for payment under such Letter of Credit, the Issuing Bank shall
     promptly notify the relevant Borrower (through the Administrative Agent or
     the Multi-Currency Payment Agent, as the case may be) of the amount to be
     paid by the Issuing Bank as a result of such demand and the date on which
     payment is to be made by the Issuing Bank to such beneficiary in respect of
     such demand. Notwithstanding the identity of the account party of any
     Letter of Credit, the relevant Borrower hereby unconditionally agrees to
     pay and reimburse the Administrative Agent or the Multi-Currency Payment
     Agent, as the case may be, for account of the Issuing Bank for the amount
     of each demand for payment under such Letter of Credit that is in
     substantial compliance with the provisions of such Letter of Credit at or
     prior to the date on which payment is to be made by the Issuing Bank to the
     beneficiary thereunder, without presentment, demand, protest or other
     formalities of any kind.

          (d) Forthwith upon its receipt of a notice referred to in paragraph
     (c) of this Section 2.08, the relevant Borrower shall advise the
     Administrative Agent or the Multi-Currency Payment Agent, as the case may
     be, whether or not such Borrower intends to borrow hereunder to finance its
     obligation to reimburse the Issuing Bank for the amount of the related
     demand for payment and, if it does, submit a notice of such borrowing as
     provided in Section 5.05 hereof.

          (e) Each Lender (other than the Issuing Bank) shall pay to the
     Administrative Agent or the Multi-Currency Payment Agent, as the case may
     be, for account of the

<Page>

                                                                              35

     Issuing Bank at an account in New York, New York specified by the
     Administrative Agent (or the Multi-Currency Payment Agent, as the case may
     be) in Dollars and in immediately available funds the amount of such
     Lender's US$ Commitment Percentage or Multi-Currency Commitment Percentage,
     as the case may be, of any payment under a Letter of Credit issued under
     the US$ Commitments or the Multi-Currency Commitments, as the case may be,
     upon notice by the Issuing Bank (through the Administrative Agent) to such
     Lender requesting such payment and specifying such amount. Each such
     Lender's obligation to make such payment to the Administrative Agent or the
     Multi-Currency Payment Agent, as the case may be, for account of the
     Issuing Bank under this paragraph (e), and the Issuing Bank's right to
     receive the same, shall be absolute and unconditional and shall not be
     affected by any circumstance whatsoever (other than gross negligence or
     wilful misconduct of the Issuing Bank), including, without limitation, the
     failure of any other Lender to make its payment under this paragraph (e),
     the financial condition of the Company or the Borrowers (or any other
     account party), any failure to satisfy any condition precedent to any Loan,
     the existence of any Default or the termination of the Commitments. Each
     such payment to the Issuing Bank shall be made without any offset,
     abatement, withholding or reduction whatsoever. If any Lender shall default
     in its obligation to make any such payment to the Administrative Agent or
     the Multi-Currency Payment Agent, as the case may be, for account of the
     Issuing Bank, for so long as such default shall continue the Administrative
     Agent or the Multi-Currency Payment Agent, as the case may be, may at the
     request of the Issuing Bank withhold from any payments received by the
     Administrative Agent or the Multi-Currency Payment Agent, as the case may
     be, under this Agreement or any Note for account of such Lender the amount
     so in default and, to the extent so withheld, pay the same to the Issuing
     Bank in satisfaction of such defaulted obligation.

          (f) Upon the making of each payment by a Lender to the Issuing Bank
     pursuant to paragraph (e) above in respect of any Letter of Credit, such
     Lender shall, automatically and without any further action on the part of
     the Administrative Agent (or the Multi-Currency Payment Agent, as the case
     may be), the Issuing Bank or such Lender, acquire (i) a participation in an
     amount equal to such payment in the Reimbursement Obligation owing to the
     Issuing Bank hereunder and under the Letter of Credit Documents relating to
     such Letter of Credit and (ii) a participation in a percentage equal to
     such Lender's US$ Commitment Percentage or Multi-Currency Percentage, as
     the case may be, in any interest or other amounts payable by the relevant
     Borrower hereunder and under such Letter of Credit Documents in respect of
     such Reimbursement Obligation (other than the commissions, charges, costs
     and expenses payable to the Issuing Bank pursuant to paragraph (g) of this
     Section 2.08). Upon receipt by the Issuing Bank from or for account of the
     relevant Borrower of any payment in respect of any Reimbursement Obligation
     or any such interest or other amount (including by way of setoff or
     application of proceeds of any collateral security) the Issuing Bank shall
     promptly pay to the Administrative Agent (or the Multi-Currency Payment
     Agent, as the case may be) for account of each Lender entitled thereto such
     Lender's US$ Commitment Percentage or Multi-Currency Percentage, as the
     case may be, of such payment, each such payment by the Issuing Bank to be
     made in the same money and funds in which received by the Issuing Bank. In
     the event any payment received by the Issuing Bank and so paid to the
     Lenders hereunder is rescinded or must otherwise be returned by the

<Page>

                                                                              36

     Issuing Bank, each Lender shall, upon the request of the Issuing Bank
     (through the Administrative Agent or the Multi-Currency Payment Agent, as
     the case may be), repay to the Issuing Bank (through the Administrative
     Agent or the Multi-Currency Payment Agent, as the case may be) the amount
     of such payment paid to such Lender, with interest at the rate specified in
     paragraph (j) of this Section 2.08.

          (g) The Company shall pay to the Administrative Agent or the
     Multi-Currency Payment Agent, as the case may be, for account of the
     Lenders (ratably in accordance with their respective US$ Commitment
     Percentages or Multi-Currency Percentages, as the case may be) a letter of
     credit fee in Dollars in respect of each Letter of Credit in an amount
     equal to the Applicable L/C Percentage of the daily average undrawn stated
     amount of such Letter of Credit for the period from and including the date
     of issuance of such Letter of Credit (i) in the case of a Letter of Credit
     that expires in accordance with its terms, to and including such expiration
     date and (ii) in the case of a Letter of Credit that is drawn in full or is
     otherwise terminated other than on the stated expiration date of such
     Letter of Credit, to but excluding the date such Letter of Credit is drawn
     in full or is terminated (such fee to be non-refundable, to be paid in
     arrears on each Quarterly Date and on the Commitment Termination Date and
     on the date of expiry or termination or full utilization of such Letter of
     Credit and to be calculated for any day after giving effect to any payments
     made under such Letter of Credit on such day). In addition, the Company
     shall pay to the Administrative Agent or the Multi-Currency Payment Agent,
     as the case may be, for account of the Issuing Bank a fronting fee in
     Dollars in respect of each Letter of Credit in an amount equal to 0.25% per
     annum of the daily average undrawn stated amount of such Letter of Credit
     for the period from and including the date of issuance of such Letter of
     Credit (i) in the case of a Letter of Credit that expires in accordance
     with its terms, to and including such expiration date and (ii) in the case
     of a Letter of Credit that is drawn in full or is otherwise terminated
     other than on the stated expiration date of such Letter of Credit, to but
     excluding the date such Letter of Credit is drawn in full or is terminated
     (such fee to be non-refundable, to be paid in arrears on each Quarterly
     Date and on the Commitment Termination Date and to be calculated for any
     day after giving effect to any payments made under such Letter of Credit on
     such day) plus all commissions, charges, costs and expenses in the amounts
     customarily charged by the Issuing Bank from time to time in like
     circumstances with respect to the issuance of each Letter of Credit and
     drawings and other transactions relating thereto.

          (h) Promptly following the end of each calendar month, the Issuing
     Bank shall deliver (through the Administrative Agent or the Multi-Currency
     Payment Agent, as the case may be) to each Lender and each Borrower a
     notice describing the aggregate amount of all Letters of Credit outstanding
     at the end of such month. Upon the request of any Lender from time to time,
     the Issuing Bank shall deliver any other information reasonably requested
     by such Lender with respect to each Letter of Credit then outstanding.

          (i) The issuance by the Issuing Bank of each Letter of Credit shall,
     in addition to the conditions precedent set forth in Section 7 hereof, be
     subject to the conditions precedent that (i) such Letter of Credit shall be
     in such form, contain such terms and

<Page>

                                                                              37

     support such transactions as shall be satisfactory to the Issuing Bank
     consistent with its then current practices and procedures with respect to
     letters of credit of the same type, (ii) such Letter of Credit shall be
     denominated in Dollars or a Multi-Currency and (iii) the relevant Borrower
     shall have executed and delivered such applications, agreements and other
     instruments relating to such Letter of Credit as the Issuing Bank shall
     have reasonably requested consistent with its then current practices and
     procedures with respect to letters of credit of the same type, provided
     that in the event of any conflict between any such application, agreement
     or other instrument and the provisions of this Agreement or any Security
     Document, the provisions of this Agreement and the Security Documents shall
     control.

          (j) To the extent that any Lender shall fail to pay any amount
     required to be paid pursuant to paragraph (e) or (f) of this Section 2.08
     on the due date therefor, such Lender shall pay interest to the Issuing
     Bank (through the Administrative Agent or the Multi-Currency Payment Agent,
     as the case may be) on such amount from and including such due date to but
     excluding the date such payment is made at a rate per annum equal to the
     Federal Funds Effective Rate or, in the case of any amount payable in a
     currency other than Dollars, the rate determined by the Administrative
     Agent or the Multi-Currency Payment Agent (in the case of Letters of Credit
     issued under the Multi-Currency Commitments) in its discretion as the
     appropriate rate for interbank settlements, PROVIDED that if such Lender
     shall fail to make such payment to the Issuing Bank within three Business
     Days of such due date, then, retroactively to the due date, such Lender
     shall be obligated to pay interest on such amount at the rate then payable
     by the relevant Borrower on such amount.

          (k) The issuance by the Issuing Bank of any modification or supplement
     to any Letter of Credit hereunder shall be subject to the same conditions
     as are applicable under this Section 2.08 to the issuance of new Letters of
     Credit, and no such modification or supplement shall be issued hereunder
     unless either (i) the respective Letter of Credit affected thereby would
     have complied with such conditions had it originally been issued hereunder
     in such modified or supplemented form or (ii) each Lender shall have
     consented thereto.

The Company hereby indemnifies and holds harmless each Lender (including the
Issuing Bank, the Administrative Agent and the Multi-Currency Payment Agent)
from and against any and all claims and damages, losses, liabilities, costs or
expenses that such Lender, the Administrative Agent or the Multi-Currency
Payment Agent may incur (or that may be claimed against such Lender, the
Administrative Agent or the Multi-Currency Payment Agent by any Person
whatsoever) by reason of or in connection with the execution and delivery or
transfer of or payment or refusal to pay by the Issuing Bank under any Letter of
Credit; PROVIDED that the Company shall not be required to indemnify any Lender,
the Administrative Agent or the Multi-Currency Payment Agent for any claims,
damages, losses, liabilities, costs or expenses to the extent, but only to the
extent, caused by (x) the willful misconduct or gross negligence of the Issuing
Bank in determining whether a request presented under any Letter of Credit
complied with the terms of such Letter of Credit or (y) in the case of the
Issuing Bank, its failure to pay under any Letter of Credit after the
presentation to it of a request strictly complying with the terms and conditions
of such Letter of Credit. Nothing in this Section 2.08 is intended to limit the

                                                                              38

other obligations of any Borrower, any Lender, the Administrative Agent or the
Multi-Currency Payment Agent under this Agreement.

          2.09. CURRENCY FLUCTUATIONS, ETC.

          (a) Not later than 1:00 p.m., New York City time, on each Calculation
Date, the Multi-Currency Payment Agent shall (i) determine the Exchange Rate as
of such Calculation Date with respect to (x) each Multi-Currency for which there
are at such time outstanding Multi-Currency Loans or Letters of Credit issued
under the Multi-Currency Commitments and (y) the Canadian Dollar if there are at
such time outstanding non-Dollar-denominated US$-Canadian Loans, and (ii) give
notice thereof to the Multi-Currency Lenders which have committed to make
Multi-Currency Loans in each such Multi-Currency, to the US$-Canadian Lenders
which have committed to make US$-Canadian Loans in Canadian Dollars and to the
Company. The Exchange Rates so determined shall become effective on the first
Business Day immediately following the relevant Calculation Date (a "Reset
Date") and shall remain effective until the next succeeding Reset Date.

          (b) Not later than 5:00 p.m., New York City time, on each Reset Date,
the Multi-Currency Payment Agent shall (i) determine (x) the Dollar Equivalent
of the Multi-Currency Loans or Letter of Credit Liabilities under the
Multi-Currency Commitments in each Multi-Currency then outstanding (after giving
effect to any Multi-Currency Loans to be made or repaid on such date) and (y)
the Dollar Equivalent of the non-Dollar-denominated US$-Canadian Loans or Letter
of Credit Liabilities under the US$-Canadian Commitments and denominated in
Canadian Dollars then outstanding (after giving effect to any
non-Dollar-denominated US$-Canadian Loans to be made or repaid on such date)and
(ii) notify the Multi-Currency Lenders or the US$-Canadian Lenders, as the case
may be, and the Company of the results of such determination.

          (c) If on any Reset Date, the Dollar Equivalent of the aggregate
principal amount of Multi-Currency Loans and Letters of Credit issued under the
Multi-Currency Commitments outstanding exceeds 105% of the aggregate principal
amount of the Multi-Currency Commitments, then the Company shall, within three
Business Days after notice thereof from the Multi-Currency Payment Agent, prepay
(in any Multi-Currency as selected by the Company) Multi-Currency Loans in an
aggregate amount such that, after giving effect thereto, the Dollar Equivalent
of all such Multi-Currency Loans, together with Letters of Credit issued under
the Multi-Currency Commitments, shall be equal to or less than such aggregate
amount of Multi-Currency Commitments (and in the event that after such
prepayment, the Dollar Equivalent of the outstanding stated amount of the
Letters of Credit issued under the Multi-Currency Commitments is more than such
aggregate amount of the Multi-Currency Commitments, the Company shall provide
cash cover for the difference by paying to the Multi-Currency Payment Agent
immediately available funds in an amount equal to such difference, which funds
shall be retained by the Multi-Currency Payment Agent in the Collateral Account
as such collateral security for such Letter of Credit Liabilities). If any such
prepayment occurs on a day which is not the last day of the then current
Interest Period with respect thereto, the Company shall pay to the

                                                                              39

          (d) If on any Reset Date, the Dollars Equivalent of the aggregate
principal amount outstanding ("Outstanding Amount") of Dollar-denominated,
non-Dollar-denominated US$-Canadian Loans and Canadian Letters of Credit exceeds
105% of the aggregate principal amount of the US$-Canadian Commitments, then the
Company shall, within three Business Days after notice thereof from the
Multi-Currency Payment Agent, prepay (in Dollars or Canadian Dollars as selected
by the Company) US$-Canadian Loans or Canadian Letters of Credit in an aggregate
amount such that, after giving effect thereto, the Dollar Equivalent of all such
US$-Canadian Loans and Canadian Letters of Credit shall be equal to or less than
such aggregate amount of US$-Canadian Commitment. If any such prepayment occurs
on a day which is not the last day of the then current Interest Period with
respect thereto, the Company shall pay to the US$-Canadian Lenders such amounts,
if any, as may be required pursuant to Section 6.05.

<Page>

                                                                              40

provided in Section 5.05 hereof. Any prepayment of Term Loans hereunder may not
be reborrowed.

          (b) MANDATORY PREPAYMENTS. (i) If on any date, the Company or any
Subsidiary of the Company shall receive Net Cash Proceeds from any issuance
subsequent to the Effective Date of Indebtedness, other than Indebtedness
incurred pursuant to Section 9.08 hereof (except Section 9.08(vii)), or any
Accounts Receivable Financing (it being understood that this Section 3.02(b)
shall not constitute a waiver of any provision of Section 9.08), then the
Borrowers shall prepay the Loans (and/or provide cover for Letter of Credit
Liabilities as specified in paragraph (d) below) in an amount equal to such Net
Cash Proceeds (less any prepayments of the C$ Loans under Section 3.4(b) of
Annex A hereto), but, the Revolving Commitments shall not be subject to
automatic reduction.

          (ii) Amounts to be applied in connection with prepayments made
pursuant to this Section 3.02(b) shall be applied, FIRST, to the prepayment of
the Term Loans (which may not be reborrowed) and, SECOND, to the prepayment of

          (c) COMMITMENT REDUCTIONS; TERM LOAN PREPAYMENTS. (i) If on any date,
the Company or any Subsidiary of the Company shall receive Net Cash Proceeds
from any disposition of assets or any Recovery Event, then, unless such
disposition of assets or Recovery Event shall be a Reinvestment Event, the
Revolving Commitments shall be reduced or the Term Loans prepaid, as the case
may be, by an amount equal to such Net Cash Proceeds to the extent such Net Cash
Proceeds, together with all other such Net Cash Proceeds from dispositions of
assets or Recovery Events that are not Reinvestment Events, exceeds $15,000,000
in the then-current fiscal year of the Company; PROVIDED, that notwithstanding
the foregoing, (i) the aggregate Net Cash Proceeds from dispositions of assets
and Recovery Events that may be excluded from the foregoing requirement for a
Reinvestment Event shall not exceed 10% of the Consolidated Net Tangible Assets
of the Company as at the end of the immediately preceding fiscal year and (ii)
on each Reinvestment Prepayment Date, an amount equal to the Reinvestment
Prepayment Amount with respect to the relevant Reinvestment Event shall be
applied toward the reduction of the Revolving Commitments or the prepayment of
the Term Loans, as the case may be.

          (ii) Amounts to be applied in connection with prepayments and
Revolving Commitment reductions made pursuant to this Section 3.02(c) shall be
applied, FIRST, to the prepayment of the Term Loans (which may not be
reborrowed) and, SECOND, to reduce permanently the Revolving Commitments. Each
prepayment of the Loans under this Section 3.02(c) shall be accompanied by
accrued interest to the date of such prepayment on the amount prepaid. To the
extent that, after giving effect to any such reduction of the Revolving
Commitments, the aggregate principal amount of the US$ Loans, the US$-Canadian
Loans or the Multi-Currency Loans and the aggregate amount of Letter of Credit
Liabilities under the US$ Commitments, US$-Canadian Commitments or the
Multi-Currency Commitments, as the case may be, would exceed such Commitments,
the Borrowers shall, first, prepay Loans thereunder and, second, provide cover
for Letter of Credit Liabilities thereunder as specified in paragraph (d) below,
in an aggregate amount equal to such excess. The Company shall notify the

<Page>

                                                                              41

Administrative Agent promptly upon the occurrence of any event giving rise to a
prepayment or Commitment reduction under this Section 3.02(c).

          (d) COVER FOR LETTER OF CREDIT LIABILITIES. In the event that the US$
Loans or the Multi-Currency Loans have been repaid in full, amounts payable
under Section 3.02(b) or 3.02(c) shall be applied to provide cash cover for
outstanding Letters of Credit under the US$ Commitments or the Multi-Currency
Commitments, as the case may be, in which event the Company shall effect the
same by paying to the Administrative Agent or the Multi-Currency Payment Agent,
as the case may be, immediately available funds in an amount equal to the
required amount, which funds shall be retained by the Administrative Agent or
the Multi-Currency Payment Agent in the Collateral Account on behalf of the
Lenders as collateral security for such Letter of Credit Liabilities until such
time as the Letters of Credit under such Commitments shall have been terminated
and all of the Letter of Credit Liabilities paid in full.

          3.03. PROCEDURE FOR SWINGLINE BORROWING; REFUNDING OF SWINGLINE LOANS.

          (a) NOTICE AND BORROWING OF SWINGLINE LOANS. Whenever the Company
desires that the Swingline Lender make Swingline Loans it shall give the
Swingline Lender irrevocable telephonic notice confirmed promptly in writing
(which telephonic notice must be received by the Swingline Lender not later than
11:00 a.m., New York City time, on the proposed Borrowing Date), specifying (i)
the amount to be borrowed and (ii) the requested Borrowing Date (which shall be
a Business Day during the Commitment Period). Each borrowing under the Swingline
Commitment shall be in an amount equal to $500,000 or a whole multiple of
$100,000 in excess thereof. Not later than 3:00 p.m., New York City time, on the
Borrowing Date specified in a notice in respect of Swingline Loans, the
Swingline Lender shall make available to the Administrative Agent at the
Applicable Lending Office an amount in immediately available funds equal to the
amount of the Swingline Loan to be made by the Swingline Lender. The
Administrative Agent shall make the proceeds of such Swingline Loan available to
the Company on such Borrowing Date by depositing such proceeds in the account of
the Company with the Administrative Agent on such Borrowing Date in immediately
available funds.

          (b) REFUNDED SWINGLINE LOANS. The Swingline Lender, at any time and
from time to time in its sole and absolute discretion may, on behalf of the
Company (which hereby irrevocably directs the Swingline Lender to act on its
behalf), on one Business Day's notice given by the Swingline Lender no later
than 12:00 Noon, New York City time, request each US$ Lender to make, and each
US$ Lender hereby agrees to make, a US$ Loan, in an amount equal to such US$
Lender's US$ Commitment Percentage of the aggregate amount of the Swingline
Loans (the "REFUNDED SWINGLINE LOANS") outstanding on the date of such notice,
to repay the Swingline Lender. Each US$ Lender shall make the amount of such US$
Loan available to the Administrative Agent at the Applicable Lending Office in
immediately available funds, not later than 10:00 a.m., New York City time, one
Business Day after the date of such notice. The proceeds of such US$ Loans shall
be immediately made available by the Administrative Agent to the Swingline
Lender for application by the Swingline Lender to the repayment of the Refunded
Swingline Loans. The Company irrevocably authorizes the Swingline Lender, on one
Business Day's notice given by the Swingline Lender no later than 12:00 Noon,
New York City time, to charge the Company's accounts with the Administrative
Agent (up to the amount available in

<Page>

                                                                              42

each such account) in order to pay the amount of such Refunded Swingline Loans
to the extent amounts received from the US$ Lenders are not sufficient to repay
in full such Refunded Swingline Loans.

          (c) SWINGLINE PARTICIPATION AMOUNT. If prior to the time a US$ Loan
would have otherwise been made pursuant to Section 3.03(b), one of the events
described in Section 10.01(f) shall have occurred and be continuing with respect
to the Company or if for any other reason, as determined by the Swingline Lender
in its sole discretion, US$ Loans may not be made as contemplated by Section
3.03(b), each US$ Lender shall, on the date such US$ Loan was to have been made
pursuant to the notice referred to in Section 3.03(b), purchase for cash an
undivided participating interest in the then outstanding Swingline Loans by
paying to the Swingline Lender an amount (the "SWINGLINE PARTICIPATION AMOUNT")
equal to (i) such US$ Lender's US$ Commitment Percentage TIMES (ii) the sum of
the aggregate principal amount of Swingline Loans then outstanding that were to
have been repaid with such US$ Loans.

          (d) DISTRIBUTION OF SWINGLINE PARTICIPATION AMOUNT. Whenever, at any
time after the Swingline Lender has received from any US$ Lender such Lender's
Swingline Participation Amount, the Swingline Lender receives any payment on
account of the Swingline Loans, the Swingline Lender will distribute to such
Lender its Swingline Participation Amount (appropriately adjusted, in the case
of interest payments, to reflect the period of time during which such Lender's
participating interest was outstanding and funded and, in the case of principal
and interest payments, to reflect such Lender's PRO RATA portion of such payment
if such payment is not sufficient to pay the principal of and interest on all
Swingline Loans then due); PROVIDED, HOWEVER, that in the event that such
payment received by the Swingline Lender is required to be returned, such US$
Lender will return to the Swingline Lender any portion thereof previously
distributed to it by the Swingline Lender.

          (e) OBLIGATION ABSOLUTE. Each US$ Lender's obligation to make the
Loans referred to in Section 3.03(b) and to purchase participating interests
pursuant to Section 3.03(c) shall be absolute and unconditional and shall not be
affected by any circumstance, including (i) any setoff, counterclaim,
recoupment, defense or other right that such US$ Lender or the Company may have
against the Swingline Lender, the Company or any other Person for any reason
whatsoever; (ii) the occurrence or continuance of a Default or an Event of
Default or the failure to satisfy any of the other conditions specified in
Section 7; (iii) any adverse change in the condition (financial or otherwise) of
the Company; (iv) any breach of this Agreement or any other Basic Document by
the Company, any other Obligor or any other US$ Lender; or (v) any other
circumstance, happening or event whatsoever, whether or not similar to any of
the foregoing.

          (f) NO AMENDMENT, WAIVER OR CONSENT. No amendment, waiver or consent
shall be made with respect to this Section 3.03 and Section 2.01(c) without the
consent of the Swingline Lender and the Administrative Agent.

          (a) The Borrowers hereby promise to pay to the Administrative Agent or
the Multi-Currency Payment Agent, as the case may be, for the account of each
Revolving Lender the entire outstanding principal amount of such Lender's
Revolving Loans, and each Revolving Loan shall mature, on the Commitment
Termination Date.

          (b) The aggregate principal amount of the Term Loans shall mature and
be payable in consecutive quarterly installments, on the dates and in the

</Table>

               PROVIDED, HOWEVER, that if on or prior to April 15, 2007 the
$120,000,000 9-1/8% Senior Subordinated Notes due July 15, 2007 shall not have
been redeemed, repurchased or defeased in full in a manner in accordance with
this Agreement, the Term Loans shall mature and, to the extent then outstanding,
be payable in full on April 15, 2007.

          4.02. INTEREST. Each Borrower will pay to the Administrative Agent or,
in the case of Multi-Currency Loans or non-Dollar-denominated US$-Canadian
Loans, to the Multi-Currency Payment Agent, for the account of each Lender
interest on the unpaid principal amount of each Loan made by such Lender to such
Borrower for the period commencing on the date of such Loan to but excluding the
date such Loan shall be paid in full, at the following rates per annum:

          (a) if such Loan is an ABR Loan, the Alternate Base Rate PLUS the
Applicable Margin; and

<Page>

                                                                              44

          (b) if such Loan is a Eurocurrency Loan, the Eurocurrency Rate PLUS
     the Applicable Margin.

          Notwithstanding the foregoing, each Borrower hereby promises to pay to
the Administrative Agent or, in the case of Multi-Currency Loans or
non-Dollar-denominated US$-Canadian Loans, to the Multi-Currency Payment Agent,
for account of each Lender interest at the applicable Post-Default Rate (x) on
any principal of any Loan made by such Lender to such Borrower, on any
Reimbursement Obligation held by such Lender and on any other amount payable by
such Borrower hereunder or under the Note held by such Lender to or for account
of such Lender (but, if such amount is interest, only to the extent legally
enforceable), that shall not be paid in full when due (whether at stated
maturity, by acceleration, by mandatory prepayment or otherwise), for the period
from and including the due date thereof to but excluding the date the same is
paid in full and (y) during any period when an Event of Default shall have
occurred under Section 10.01(a) hereof and for so long as such Event of Default
shall be continuing, on any principal of any Loan made by such Lender to such
Borrower.

          Accrued interest on each Loan shall be payable (i) if such Loan is an
ABR Loan, on each Quarterly Date, (ii) if such Loan is a Eurocurrency Loan, on
the last day of each Interest Period for such Loan (and, if such Interest Period
exceeds three months' duration, quarterly, commencing on the first quarterly
anniversary of the first day of such Interest Period), and (iii) in any event,
upon the payment, prepayment or conversion thereof, but only on the principal so
paid or prepaid or converted; PROVIDED that interest payable at the Post-Default
Rate shall be payable from time to time on demand of the Administrative Agent
(or the Multi-Currency Payment Agent, in the case of Multi-Currency Loans or
non-Dollar-denominated US$-Canadian Loans,) or the Majority Lenders. Promptly
after the determination of any interest rate provided for herein or any change
therein, the Administrative Agent shall notify the Lenders and each Borrower
thereof.

          Notwithstanding the foregoing provisions of this Section 4.02, if at
any time the rate of interest set forth above on any Loan of any Lender (the
"Stated Rate" for such Loan) exceeds the maximum non-usurious interest rate
permissible for such Lender to charge commercial borrowers under applicable law
(the "Maximum Rate" for such Lender), the rate of interest charged on such Loan
of such Lender hereunder shall be limited to the Maximum Rate for such Lender.

          In the event the Stated Rate for any Loan of a Lender that has
theretofore been subject to the preceding paragraph at any time is less than the
Maximum Rate for such Lender, the principal amount of such Loan shall bear
interest at the Maximum Rate for such Lender until the total amount of interest
paid to such Lender or accrued on its Loans hereunder equals the amount of
interest which would have been paid to such Lender or accrued on such Lender's
Loans hereunder if the Stated Rate had at all times been in effect.

          In the event, upon payment in full of all amounts payable hereunder,
the total amount of interest paid to any Lender or accrued on such Lender's
Loans under the terms of this Agreement is less than the total amount of
interest which would have been paid to such Lender or accrued on such Lender's
Loans if the Stated Rate had, at all times, been in effect, then the relevant
Borrower shall, to the extent permitted by applicable law, pay to the
Administrative

<Page>

                                                                              45

Agent or, in the case of Multi-Currency Loans or non-Dollar-denominated
US$-Canadian Loans, to the Multi-Currency Payment Agent, for the account of such
Lender an amount equal to the difference between (a) the lesser of (i) the
amount of interest which would have accrued on such Lender's Loans if the
Maximum Rate for such Lender had at all times been in effect or (ii) the amount
of interest which would have accrued on such Lender's Loans if the Stated Rate
had at all times been in effect and (b) the amount of interest actually paid to
such Lender or accrued on its Loans under this Agreement. In the event any
Lender ever receives, collects or applies as interest any sum in excess of the
Maximum Rate for such Lender, such excess amount shall be applied to the
reduction of the principal balance of its Loans or to other amounts (other than
interest) payable hereunder, and if no such principal is then outstanding, such
excess or part thereof remaining shall be paid to such Borrower.

          Section 5 PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS; ETC.

          5.01. PAYMENTS.

          (a) Except to the extent otherwise provided herein, all payments of
principal, interest, Reimbursement Obligations and other amounts to be made by
any Borrower under the US$ Commitments, the US$-Canadian Commitments, the
Multi-Currency Commitments or the Term Commitments and under the corresponding
Notes shall (except in the case of payments of principal and interest on
Multi-Currency Loans or Letter of Credit Liabilities incurred under the
Multi-Currency Commitments or non-Dollar-denominated US$-Canadian Loans) be made
in Dollars, in immediately available funds, to the Administrative Agent at an
account in New York, New York specified by the Administrative Agent, not later
than 11:00 a.m. New York time on the date on which such payment shall become due
(each such payment made after such time on such due date to be deemed to have
been made on the next succeeding Business Day). The Administrative Agent, or any
Lender for whose account any such payment is made, may (but shall not be
obligated to) debit the amount of any such payment which is not made by such
time to any ordinary deposit account of such Borrower with the Administrative
Agent or such Lender, as the case may be. The relevant Borrower shall, at the
time of making each such payment, specify to the Administrative Agent the Loans
or other amounts payable by such Borrower hereunder to which such payment is to
be applied (and in the event that it fails to so specify, or if an Event of
Default has occurred and is continuing, the Administrative Agent may apply such
payment for the benefit of the Lenders as it may elect in its sole discretion,
but subject to the other terms and conditions of this Agreement, including
without limitation, Section 5.02 hereof). Each payment received by the
Administrative Agent under the US$ Commitments, the US$-Canadian Commitments,
the Multi-Currency Commitments or the Term Commitments or under any
corresponding Note (except in the case of payment of principal and interest on
Multi-Currency Loans or Letter of Credit Liabilities incurred under the
Multi-Currency Commitments or non-Dollar-denominated US$-Canadian Loans) for the
account of a Lender shall be paid promptly to such Lender, in immediately
available funds, for the account of such Lender's Applicable Lending Office. If
the due date of any such payment would otherwise fall on a day which is not a
Business Day such date shall be extended to the next succeeding Business Day and
interest shall be payable for any principal so extended for the period of such
extension.

          (b) Except to the extent otherwise provided herein, all payments of
principal and interest on (i) Multi-Currency Loans and Letter of Credit
Liabilities incurred under the

<Page>

                                                                              46

Multi-Currency Commitments, (ii) non-Dollar-denominated US$-Canadian Loans and
(iii) under corresponding Notes to be made by any Borrower shall be made in the
currency of the applicable Loan or Letter of Credit for which payment is being
made, in immediately available funds, to the Multi-Currency Payment Agent at an
account in London specified by the Multi-Currency Payment Agent, not later than
11:00 a.m. London time on the date on which such payment shall become due (each
such payment made after such time on such due date to be deemed to have been
made on the next succeeding Business Day). The Multi-Currency Payment Agent, or
any Lender for whose account any such payment is made, may (but shall not be
obligated to) debit the amount of any such payment which is not made by such
time to any ordinary deposit account of such Borrower with the Multi-Currency
Payment Agent or such Lender, as the case may be. The relevant Borrower shall,
at the time of making each such payment, specify to the Multi-Currency Payment
Agent the Loans or other amounts payable by such Borrower hereunder to which
such payment is to be applied (and in the event that it fails to so specify, or
if an Event of Default has occurred and is continuing, the Multi-Currency
Payment Agent may apply such payment for the benefit of the Lenders as it may

Eurocurrency Loans within the time period and otherwise as provided in this
Section 5.05, such Loans (if outstanding as Eurocurrency Loans) will be

Interest Period for such Loans or (if outstanding as ABR Loans) will remain as,

          5.06. NON-RECEIPT OF FUNDS BY THE ADMINISTRATIVE AGENT. Unless the
Administrative Agent or the Multi-Currency Payment Agent, as the case may be,
shall have been notified by a US$ Lender, US$-Canadian Lender, Multi-Currency
Lender, Term Lender or a Borrower (the "PAYOR") prior to the date on which such
Lender is to make payment to the Administrative Agent or the Multi-Currency
Payment Agent, as the case may be, of the proceeds of a Loan to be made by it
hereunder or the Borrower is to make a payment to the Administrative Agent or
the Multi-Currency Payment Agent, as the case may be, for the account of one or
more of the Lenders, as the case may be (such payment being herein called the
"REQUIRED PAYMENT"), which notice shall be effective upon receipt, that the
Payor does not intend to make the Required Payment to the Administrative Agent
or the Multi-Currency Payment Agent, as the case may be, the Administrative
Agent or the Multi-Currency Payment Agent, as the case may be, may assume that
the Required Payment has been made and may, in reliance upon such assumption
(but shall not be required to), make the amount thereof available to the
intended recipient on such date and, if the Payor has not in fact made the
Required Payment to the Administrative Agent or the Multi-Currency Payment
Agent, as the case may be, the recipient of such payment shall, on demand, pay
to the Administrative Agent or the Multi-Currency Payment Agent, as the case may
be, the amount made available to it together with interest thereon in respect of
the period commencing on the date such amount was so made available by the
Administrative Agent or the Multi-Currency Payment Agent, as the case may be,
until the date the Administrative Agent or the Multi-Currency Payment Agent, as
the case may be, recovers such amount at a rate per annum equal to the Federal
Funds Effective Rate for such period or, in the case of an amount payable in a
currency other than Dollars, the rate determined by the Administrative Agent in
its discretion of the appropriate rate for interbank settlements.

          5.07. SHARING OF PAYMENTS; WAIVER OF ENFORCEMENT WITHOUT CONSENT. ETC.

          (a) Each Borrower agrees that, in addition to (and without limitation
of) any right of set-off, banker's lien or counterclaim a Lender may otherwise
have, each Lender shall be entitled, at its option, to offset balances held by
it or its affiliates for the account of the such Borrower at any of their
offices, in Dollars or in any other currency, against any principal of or
interest on any of such Lender's Loans or Reimbursement Obligations to such
Borrower hereunder, or any other obligation of such Borrower hereunder, which is
not paid when due (regardless of whether such balances are then due to such
Borrower), in which case it shall promptly notify the Company, the relevant
Borrower and the Administrative Agent (or the Multi-Currency Payment Agent, as
the case may be) thereof, provided that such Lender's failure to give such
notice shall not affect the validity thereof. Each Borrower agrees, to the
fullest extent it may effectively do so under applicable law, that any Person
purchasing a participation in the Loans to such Borrower made, or other
obligations held, by another Person, whether or not acquired pursuant to the
foregoing arrangements, may exercise all rights of set-off, banker's lien,

<Page>

                                                                              52

counterclaim or similar rights with respect to such participation as fully as if
such Lender were a direct holder of such Loans or other obligations in the
amount of such participation.

          (b) If a Lender shall obtain payment of any principal of or interest
on any Loan made by it under this Agreement, or on any other obligation then due
to such Lender hereunder, through the exercise of any right of set-off, banker's
lien, counterclaim or similar right, or otherwise, it shall promptly notify the
Administrative Agent (or the Multi-Currency Payment Agent, as the case may be)
and purchase from the other Lenders participations in the Loans made, or other
obligations held, by the other Lenders in such amounts, and make such other
adjustments from time to time as shall be equitable to the end that all the
Lenders shall share the benefit of such payment (net of any expenses which may
be incurred by such Lender in obtaining or preserving such benefit) pro rata in
accordance with the unpaid principal and interest on the Loans or other
obligations then due to each of them. To such end all the Lenders shall make
appropriate adjustments among themselves (by the resale of participations sold
or otherwise) if such payment is rescinded or must otherwise be restored
(including the payment of interest to the extent that the Lender obligated to
return such funds is obligated to return interest).

          (c) Nothing contained herein shall require any Lender to exercise any
right of set-off, banker's lien, counterclaim or similar right or shall affect
the right of any Lender to exercise, and retain the benefits of exercising, any
such right with respect to any other indebtedness or obligation of any Borrower.

          (d) This Section 5.07 is for the benefit of the Lenders only and does
not constitute a waiver of any rights against any Borrower or any of their
Subsidiaries or against any property held as security for any obligations
hereunder or under any other Basic Document.

          5.08. WITHHOLDING TAX EXEMPTION.

          (a) At least five Business Days prior to the first date on which
interest or fees are payable hereunder for the account of any Lender, each
Lender that is not incorporated under the laws of the United States of America
or a state thereof agrees that it will deliver, to the extent it has not so
delivered under the Existing Credit Agreement, to each of the Company and the
Administrative Agent two duly completed copies of either U.S. Internal Revenue
Service Form W-8BEN or Form W-8ECI (or any subsequent versions thereof or
successors thereto), or, in the case of a Non-U.S. Lender claiming exemption
from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code
with respect to payments of "portfolio interest", a statement substantially in
the form of Exhibit K (any such certificate an "EXEMPTION CERTIFICATE") and a
Form W-8BEN (or any subsequent versions thereof or successors thereto),
certifying in either case that such Lender is entitled to receive payments under
this Agreement and the Notes without deduction or withholding of any United
States federal income taxes. Each Lender which so delivers a Form W-8BEN or Form
W-8ECI further undertakes to deliver to each of the Company and the
Administrative Agent (or the Multi-Currency Payment Agent, in the case of
Multi-Currency Lenders) two additional copies of such form (or a successor form)
on or before the date that such form expires or becomes obsolete or after the
occurrence of any event requiring a change in the most recent form so delivered
by it, and such amendments thereto or extensions or renewals thereof as may be
reasonably requested by the Company or the Administrative Agent (or the
Multi-Currency Payment Agent, as the case may be), in each case

<Page>

                                                                              53

certifying that such Lender is entitled to receive payments under this Agreement
and the Notes without deduction or withholding of any United States federal
income taxes, unless an event (including without limitation any change in
treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable
or which would prevent such Lender from duly completing and delivering any such
form with respect to it and such Lender advises the Company and the
Administrative Agent (or the Multi-Currency Payment Agent, as the case may be)
that it is not capable of receiving payments without any deduction or
withholding of United States federal income tax.

          (b) Each Lender that is not incorporated or organized under the laws
of the jurisdiction under which a Foreign Subsidiary Borrower is incorporated or
organized shall, upon request by such Foreign Subsidiary Borrower, deliver to
such Foreign Subsidiary Borrower or the applicable Governmental Authority, any
form or certificate required in order that any payment by such Foreign
Subsidiary Borrower under this Agreement or any Notes to such Lender may be made
free and clear of, and without deduction or withholding for or on account of any
tax (or to allow any such deduction or withholding to be at a reduced rate)
imposed on such payment under the laws of the jurisdiction under which such
Foreign Subsidiary Borrower is incorporated or organized, PROVIDED that such
Lender is legally entitled to complete, execute and deliver such form or
certificate and such completion, execution or submission would not materially
prejudice the legal position of such Lender.

          (c) All payments made by a Borrower or the Canadian Borrower under
this Agreement shall be made free and clear of, and without deduction or
withholding for or on account of, any present or future income, stamp or other
taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now
or hereafter imposed, levied, collected, withheld or assessed by any
Governmental Authority, excluding net income taxes and franchise taxes (imposed
in lieu of net income taxes) imposed on the Administrative Agent, the
Multi-Currency Payment Agent, the Canadian Administrative Agent or any Lender as
a result of a present or former connection between the Administrative Agent, the
Multi-Currency Payment Agent, the Canadian Administrative Agent or such Lender
and the jurisdiction of the Governmental Authority imposing such tax or any
political subdivision or taxing authority thereof or therein (other than any
such connection arising solely from the Administrative Agent, the Multi-Currency
Payment Agent or such Lender having executed, delivered or performed its
obligations or received a payment under, or enforced, this Agreement or any
other Loan Document). If any such non-excluded taxes, levies, imposts, duties,
charges, fees, deductions or withholdings ("NON-EXCLUDED TAXES") or other taxes
are required to be withheld from any amounts payable to the Administrative
Agent, the Multi-Currency Payment Agent, the Canadian Administrative Agent or
any Lender hereunder, the amounts so payable to the Administrative Agent, the
Multi-Currency Payment Agent, the Canadian Administrative Agent or such Lender
shall be increased to the extent necessary to yield to the Administrative Agent,
the Multi-Currency Payment Agent, the Canadian Administrative Agent or such
Lender (after payment of all Non-Excluded Taxes and other taxes) interest or any
such other amounts payable hereunder at the rates or in the amounts specified in
this Agreement, PROVIDED, HOWEVER, that the relevant Borrower or the Canadian
Borrower shall not be required to increase any such amounts payable to any
Lender with respect to any Non-Excluded Taxes (i) that are attributable to such
Lender's failure to comply with the requirements of paragraph (a) or (b) of this
Section or (ii) that are United States withholding taxes imposed on amounts
payable to such Lender at the time the Lender becomes a

                                                                              54

party to this Agreement, except to the extent that such Lender's assignor (if
any) was entitled, at the time of assignment, to receive additional amounts from
such Borrower or the Canadian Borrower with respect to such Non-Excluded Taxes
pursuant to this paragraph.

          5.09. JUDGMENT CURRENCY. If for the purpose of obtaining judgment in
any court it is necessary to convert a sum due from any Borrower or the Canadian
Borrower hereunder or under any of the Notes or the C$ Notes in the currency
expressed to be payable herein (the "specified currency") into another currency,
the parties hereto agree, to the fullest extent that they may effectively do so,
that the rate of exchange used shall be that at which in accordance with normal
banking procedures the Administrative Agent could purchase the specified
currency with other such currency at the Administrative Agent's New York Office
on the Business Day that is on or immediately following the day on which final
judgment is given. The obligations of each Borrower or the Canadian Borrower in
respect of any sum due to any Lender, the Administrative Agent, the
Multi-Currency Payment Agent or the Canadian Administrative Agent hereunder or
under any Note or C$ Note shall, notwithstanding any judgment in a currency
other than the specified currency, be discharged only to the extent that on the
Business Day following receipt by such Lender, the Administrative Agent, the
Multi-Currency Payment Agent or the Canadian Administrative Agent, as the case
may be, of any sum adjudged to be so due in such other currency such Lender, the
Administrative Agent, the Multi-Currency Payment Agent or the Canadian
Administrative Agent as the case may be, may in accordance with normal banking
procedures purchase the specified currency with such other currency. If the
amount of the specified currency so purchased is less than the sum originally
due to such Lender, the Administrative Agent, the Multi-Currency Payment Agent
or the Canadian Administrative Agent, as the case may be, in the specified
currency, each Borrower and the Canadian Borrower agrees, to the fullest extent
it may effectively do so, as a separate obligation and notwithstanding any such
judgment, to indemnify such Lender, the Administrative Agent, the Multi-Currency
Payment Agent or the Canadian Administrative Agent, as the case may be, against
such loss, and if the amount of the specified currency so purchased exceeds the
sum originally due to any Lender, the Administrative Agent the Multi-Currency
Payment Agent or the Canadian Administrative Agent, as the case may be, in the
specified currency, such Lender or the Administrative Agent, or the
Multi-Currency Payment Agent, or the Canadian Administrative Agent, as the case
may be, agrees to remit such excess to the appropriate Borrower or the Canadian
Borrower.

          Section 6 YIELD PROTECTION AND ILLEGALITY.

          6.01. ADDITIONAL COSTS.

          (a) Each Borrower shall pay to the Administrative Agent for the
account of each Lender from time to time such amounts as such Lender may
determine to be necessary to compensate it for any costs incurred by such Lender
which such Lender determines are attributable to its making or maintaining of
any Eurocurrency Loans hereunder to such Borrower or its obligation to make any
of such Loans hereunder to such Borrower, or any reduction in any amount
receivable by such Lender in respect of any of such Loans or such obligation
(such increases in costs and reductions in amounts receivable being herein
called "ADDITIONAL COSTS"), in each case resulting from any Regulatory Change
which:

<Page>

                                                                              55

               (i) changes the basis of taxation of any amounts payable to such
          Lender under this Agreement or its Notes in respect of any of such
          Loans (other than changes which affect taxes measured by or imposed on
          the overall net income of such Lender or of its Applicable Lending
          Office by the jurisdiction in which such Lender has its principal
          office or such Applicable Lending Office); or

               (ii) imposes or modifies any reserve, special deposit or similar
          requirements relating to any extensions of credit or other assets of,
          or any deposits with or other liabilities of, such Lender (including
          any of such Loans or any deposits referred to in the definition of
          "Eurocurrency Base Rate" in Section 1.01 hereof); or

               (iii) imposes any other condition affecting this Agreement (or
          any of such extensions of credit or liabilities).

Each Lender will notify the relevant Borrower through the Administrative Agent
of any event occurring after the date of this Agreement which will entitle such
Lender to compensation pursuant to this Section 6.01(a) (an "ADDITIONAL COST
EVENT") as promptly as practicable after it obtains knowledge thereof and
determines to request such compensation, and (if so requested by the Company
through the Administrative Agent) will designate a different Applicable Lending
Office for the Eurocurrency Loans of such Lender if such designation will avoid
the need for, or reduce the amount of, such compensation and will not, in the
sole opinion of such Lender, be disadvantageous to such Lender (provided that
such Lender shall have no obligation to so designate an Applicable Lending
Office located in the United States of America) PROVIDED, that a Borrower shall
not be obligated to compensate such Lender for any such Additional Costs
incurred more than 180 days prior to the time the Lender first notifies such
Borrower of such Additional Cost Event. Each Lender will furnish the relevant
Borrower with a statement setting forth the calculations and the basis therefor,
in each case in reasonable detail, and amount of each request by such Lender for
compensation under this Section 6.01(a). If any Lender requests compensation
from a Borrower under this Section 6.01(a), the relevant Borrower may, by notice
to such Lender through the Administrative Agent, suspend the obligation of such
Lender to make additional Eurocurrency Loans to such Borrower until the
Regulatory Change giving rise to such request ceases to be in effect (in which
case the provisions of Section 6.04 hereof shall be applicable).

          (b) Without limiting the effect of the foregoing provisions of this
Section 6.01, in the event that, by reason of any Regulatory Change, any Lender
either (i) incurs Additional Costs based on or measured by the excess above a
specified level of the amount of a category of deposits or other liabilities of
such Lender which includes deposits by reference to which the interest rate on
Eurocurrency Loans is determined as provided in this Agreement or a category of
extensions of credit or other assets of such Lender which includes Eurocurrency
Loans or (ii) becomes subject to restrictions on the amount of such a category
of liabilities or assets which it may hold, then, if such Lender so elects by
notice to the relevant Borrower (with a copy to the Administrative Agent), the
obligation of such Lender to make Eurocurrency Loans hereunder shall be
suspended until the date such Regulatory Change ceases to be in effect (in which
case the provisions of Section 6.04 hereof shall be applicable).

<Page>

                                                                              56

          (c) Determinations and allocations by any Lender for purposes of this
Section 6.01 of the effect of any Regulatory Change on its costs of maintaining
its obligations to make Loans or of making or maintaining Loans or on amounts
receivable by it in respect of Loans, and of the additional amounts required to
compensate such Lender in respect of any Additional Costs, shall be conclusive
absent manifest error, provided that such determinations and allocations are
made on a reasonable basis.

          (d) If any Lender demands compensation under this Section, the
relevant Borrower may, at any time upon at least three (3) Business Days' prior
notice to such Lender through the Administrative Agent, convert in full the then
outstanding Eurocurrency Loans of such Lender (in which case the relevant
Borrower shall be obligated, if such conversion is made on a day that is not the
last day of the then current Interest Period applicable to such affected
Eurocurrency Loan, to reimburse such Lender, in accordance with Section 6.05,
for any resulting loss or expense incurred by it) to an ABR Loan.

          6.02. LIMITATION ON TYPES OF LOANS. Anything herein to the contrary
notwithstanding, if, with respect to any Loans that are Eurocurrency Loans:

          (a) the Administrative Agent determines (which determination shall be
     conclusive) that quotations of interest rates for the relevant deposits
     referred to in the definition of "Eurocurrency Base Rate" in Section 1.01
     hereof are not being provided by the Reference Lenders in the relevant
     amounts or for the relevant maturities for purposes of determining the rate
     of interest for such Loans for Interest Periods therefor as provided in
     this Agreement; or

          (b) the Majority Lenders determine (which determination shall be
     conclusive) and notify the Administrative Agent that the relevant rates of
     interest referred to in the definition of "Eurocurrency Base Rate" in
     Section 1.01 thereof upon the basis of which the rates of interest for such
     Loans are to be determined do not accurately reflect the cost to such
     Lenders of making or maintaining such Loans for Interest Periods therefor;

then the Administrative Agent shall promptly notify the relevant Borrower and
each Lender thereof, and so long as such condition remains in effect, the
Lenders shall be under no obligation to make Eurocurrency Loans or to convert
ABR Loans into Eurocurrency Loans and the relevant Borrower shall, on the last
day(s) of the then current Interest Period(s) for the outstanding Eurocurrency
Loans, either prepay such Loans or convert such Loans into ABR Loans in
accordance with Section 3.02 hereof.

          6.03. ILLEGALITY. Notwithstanding any other provision of this
Agreement to the contrary, in the event that it becomes unlawful for any Lender
or its Applicable Lending Office to (a) honor its obligation to make
Eurocurrency Loans hereunder, or (b) maintain Eurocurrency Loans hereunder, then
such Lender shall promptly notify the relevant Borrower thereof through the
Administrative Agent and such Lender's obligation to make Eurocurrency Loans
hereunder shall be suspended until such time as such Lender may again make and
maintain Eurocurrency Loans (in which case the provisions of Section 6.04 hereof
shall be applicable).

<Page>

                                                                              57

          6.04. SUBSTITUTE ABR LOANS. If the obligation of any Lender to make
Eurocurrency Loans shall be suspended pursuant to Section 6.01, 6.02 or 6.03
hereof, all Loans in Dollars which would otherwise be made by such Lender as
Eurocurrency Loans shall be made instead as ABR Loans (and, if an event referred
to in Section 6.01 (b)or 6.03 hereof has occurred and such Lender so requests by
notice to the relevant Borrower with a copy to the Administrative Agent, each
Dollar-denominated Eurocurrency Loan of such Lender then outstanding shall be
automatically converted into an ABR Loan on the date specified by such Lender in
such notice) and, to the extent that Eurocurrency Loans are so made as (or
converted into) ABR Loans, all payments of principal which would otherwise be
applied to such Eurocurrency Loans shall be applied instead to such ABR Loans.

          6.05. COMPENSATION. Each Borrower shall pay to the Administrative
Agent for the account of each Lender, upon the request of such Lender through
the Administrative Agent, such amount or amounts as shall be sufficient (in the
reasonable opinion of such Lender) to compensate it for any loss, cost or
expense incurred by it as a result of:

          (a) any payment, prepayment or conversion (including, without
     limitation, an automatic conversion pursuant to Section 10.02 hereof) of a
     Eurocurrency Loan made by such Lender to such Borrower on a date other than
     the last day of an Interest Period for such Loan;

          (b) any failure by a Borrower to borrow a Eurocurrency Loan to be made
     by such Lender to such Borrower on the date for such borrowing specified in
     the relevant notice of borrowing under Section 5.05 hereof;

          (c) any failure by a Borrower to prepay a Eurocurrency Loan on the
     date specified in a notice of prepayment; or

          (d) any substitution of a Lender under Section 6.07 hereof on a date
     other than the last day of an Interest Period for each Loan of such Lender;

but excluding, in any event, loss of margin for the period after any such
payment, prepayment or conversion or failure to borrow; PROVIDED that such
Lender shall have delivered to the relevant Borrower a certificate as to the
amount of such loss and expense along with the calculation and the basis
therefor, in each case in reasonable detail.

          6.06. CAPITAL ADEQUACY. If any Lender shall determine that the
adoption of any applicable law, rule, regulation or treaty regarding capital
adequacy after the date hereof, or any change therein after the date hereof, or
any change after the date hereof in the interpretation or administration thereof
by any governmental authority, central bank or comparable agency charged with
the interpretation or administration thereof, or compliance by any Lender (or
its Applicable Lending Office) with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on capital of such Lender or any Person controlling such Lender (a
"PARENT") as a consequence of its obligations hereunder to a level below that
which such Lender (or its Parent) could have achieved but for such adoption,
change or compliance (taking into consideration its policies with respect to
capital adequacy) by an

<Page>

                                                                              58

amount deemed by such Lender to be material, then from time to time, within 15
days after demand by such Lender (with a copy to the Administrative Agent), the
relevant Borrower shall pay to such Lender such additional amount or amounts as
will compensate such Lender for such reduction. A statement of any Lender
claiming compensation under this Section and setting forth the additional amount
or amounts to be paid to it hereunder shall be conclusive absent manifest error;
provided that the determination thereof is made on a reasonable basis; and
provided further that a Borrower shall not be obligated to compensate such
Lender for any such reduction occurring more than 180 days prior to the time
such Lender first notifies such Borrower of such adoption, implementation,
change or compliance. In determining such amount, such Lender may use any
reasonable averaging and attribution methods.

          6.07. SUBSTITUTION OF LENDER. If (i) the obligation of any Lender to
make Eurocurrency Loans or the right of a Borrower to convert ABR Loans of any
Lender to Eurocurrency Loans has been suspended pursuant to Section 6.03, or
(ii) any Lender has demanded compensation under Section 6.01, 6.06 or 6.09, the
relevant Borrower shall have the right, with the assistance of the
Administrative Agent, to seek a substitute bank or banks (which may be one or
more of the Lenders) satisfactory to such Borrower and the Administrative Agent
to purchase the Notes and assume the Commitments and Loans of such Lender. Any
such Lender shall be obligated to sell the Notes, Loans and Commitments for cash
without recourse to such substitute bank or banks and to execute and deliver an
appropriately completed assignment and assumption agreement reasonably
satisfactory to the Administrative Agent and the relevant Borrower and any other
document or perform any act reasonably necessary to effect the assumption of the
rights and obligations of such substitute bank or banks.

          6.08. ADDITIONAL COSTS IN RESPECT OF LETTERS OF CREDIT. Without
limiting the obligations of the Borrowers under Section 6.01 hereof (but without
duplication), if as a result of any Regulatory Change or any risk-based capital
guideline or other requirement heretofore or hereafter issued by any government
or governmental or supervisory authority implementing at the national level the
Basle Accord there shall be imposed, modified or deemed applicable any tax,
reserve, special deposit, capital adequacy or similar requirement against or
with respect to or measured by reference to Letters of Credit issued or to be
issued hereunder and the result shall be to increase the cost to any Lender or
Lenders of issuing (or purchasing participations in) or maintaining its
obligation hereunder to issue (or purchase participations in) any Letter of
Credit hereunder or reduce any amount receivable by any Lender hereunder in
respect of any Letter of Credit (which increases in cost, or reductions in
amount receivable, shall be the result of such Lender's or Lenders' reasonable
allocation of the aggregate of such increases or reductions resulting from such
event), then, upon demand by such Lender or Lenders (through the Administrative
Agent), the relevant Borrower shall pay immediately to the Administrative Agent
for account of such Lender or Lenders, from time to time as specified by such
Lender or Lenders (through the Administrative Agent), such additional amounts as
shall be sufficient to compensate such Lender or Lenders (through the
Administrative Agent) for such increased costs or reductions in amount. A
statement as to such increased costs or reductions in amount incurred by any
such Lender or Lenders, showing calculations and the basis therefor in
reasonable detail, submitted by such Lender or Lenders to the relevant Borrower,
shall be conclusive in the absence of manifest error as to the amount thereof.

<Page>

                                                                              59

          6.09. FOREIGN BORROWER COSTS. (a) If the cost to any Lender of making
or maintaining any Loan to a Foreign Subsidiary Borrower is increased, or the
amount of any sum received or receivable by any Lender (or its Applicable
Lending Office) is reduced, by an amount deemed by such Lender to be material,
by reason of the fact that such Borrower is organized under the laws of, or
principally conducts its business in, a jurisdiction or jurisdictions outside
the United States of America, such Borrower shall indemnify such Lender for such
increased cost or reduction within 15 days after demand by such Lender (with a
copy to the Administrative Agent). A certificate of such Lender claiming
compensation under this subsection (a) and setting forth the additional amount
or amounts to be paid to it hereunder, together with calculations in reasonable
detail supporting such amounts, shall be conclusive in the absence of clearly
demonstrable error. No such compensation may be claimed (x) in respect of any
Loan for any period prior to the date 90 days before the date of notice by such
Lender to the Company of its intention to make claims therefor or (y) to the
extent such Lender was aware of such cost or reduction at the time the related
Loan was made.

          (b) Each Lender will promptly notify the Company and the
Administrative Agent of any event of which it has knowledge that will entitle
such Lender to additional interest or payments pursuant to the foregoing
subsection (a) and will designate a different Applicable Lending Office, if, in
the judgment of such Lender, such designation will avoid the need for, or reduce
the amount of, such compensation and will not be otherwise disadvantageous to
such Lender.

that, as of the date of such Loan or such issuance, and before and after giving
effect thereto:

          (a) no Default shall have occurred and be continuing;

          (b) the representations and warranties made by each of the Company,
     the Canadian Borrower, any other Borrower and the Subsidiary Guarantors in
     each Basic Document to which it is a party shall be true on and as of the
     date of the making of such Loan or such issuance, with the same force and
     effect as if made on and as of such date; provided that the representations

     such earlier date); and

          (c) the borrowing of such Loan by the Company, the Canadian Borrower
     or any other Borrower hereunder or the issuance of such Letter of Credit,
     as the case may be, and the related incurrence of obligations by the
     Company, the Canadian Borrower or any other Borrower does not violate the
     provisions of any Senior Subordinated Debt Indenture or any other Senior
     Subordinated Debt Document.

Each notice of borrowing by the Company, the Canadian Borrower or any other
Borrower hereunder shall constitute a certification by the Company, the Canadian

sentence (both as of the date of such notice and, unless the Company, the
Canadian Borrower or such other Borrower otherwise notifies the Administrative
Agent prior to the date of such borrowing or issuance, as of the date of such

          7.03. FIRST LOAN TO A SUBSIDIARY BORROWER. The obligation of each

Election to Participate, this Agreement and the Notes of such Subsidiary
Borrower, and for any other matters relevant thereto, all in form and substance
reasonably satisfactory to the Administrative Agent.

          Section 8 REPRESENTATIONS AND WARRANTIES. The Company represents and
warrants to the Lenders and the Administrative Agent, as of the Effective Date
and on the date of each Loan and of the issuance of each Letter of Credit, as
follows:

          8.01. CORPORATE EXISTENCE. Each of the Company and its Subsidiaries:
(a) is duly organized, validly existing and in good standing under the laws of
the jurisdiction of its formation; (b) has all requisite power, and has all
governmental licenses, authorizations, consents, permits and approvals
(including any license, authorization, consent, permit and approval required
under any Environmental Law) necessary to own its assets and carry on its
business as now being or as proposed to be conducted (except such licenses,
authorizations, consents and approvals the lack of which, in the aggregate, will
not have a Material Adverse Effect); and (c) is qualified to do business in all
jurisdictions in which the nature of the business conducted by it makes such
qualification necessary and where failure so to qualify would have a Material
Adverse Effect.

hereunder and under the Company Guaranty and the Guarantees of such Indebtedness

     and its Subsidiaries as at the end of, and for, such fiscal year, and
     stating (or indicating in a footnote to such financial statements) that, in

     reason to know that any Default has occurred and is continuing, a notice of
     such Default, describing the same in reasonable detail;

cause each of its Subsidiaries to pay and discharge, all material taxes,
assessments and governmental charges or levies imposed upon it or upon its
income or profits, or upon any property belonging to it, prior to the date on
which penalties attach thereto, and all lawful claims which, if unpaid, might
become a Lien upon the property of the Company or such Subsidiary, provided that
neither the Company nor such Subsidiary shall be required to pay any such tax,
assessment, charge, levy or claim the payment of which is being contested in
good faith and by proper proceedings if it maintains adequate reserves with
respect thereto.

          9.03. INSURANCE. The Company will maintain, and will cause each of its
Subsidiaries to maintain, insurance with responsible companies in such amounts
and against such risks as is usually carried by owners of similar businesses and
properties in the same general areas in which the Company and its Subsidiaries
operate, provided that in any event the Company shall maintain or cause to be
maintained:

          (1) PROPERTY INSURANCE -- insurance against loss or damage covering
     all of the tangible real and personal property and improvements of the
     Company and its Subsidiaries, by reason of any Peril (as defined below), in
     amounts as shall be reasonable and customary, but in no event less than the
     functional replacement cost of all such real and personal property and
     improvements. Such policy shall include insurance against loss of operating
     income earned from the operation of the business of the Company and its
     Subsidiaries, by reason of any Peril affecting the operation thereof, and
     insurance against any other insurable loss of operating income by reason of
     any business interruption affecting the Company to the extent covered by
     standard business interruption policies in the States in which the
     Properties are located.

                                                                              69

          (2) EARTHQUAKE INSURANCE -- insurance against loss or damage covering
     all of the tangible real and personal property and improvements of the
     Company and its Subsidiaries, by reason of any earthquake peril, in amounts
     as shall be reasonable, customary and commercially available in the
     property/casualty insurance markets.

Such insurance shall be written by financially responsible companies selected by
the Company, having an A.M. Best rating of "A-" or better and in a financial
size category acceptable to the Majority Lenders, or by other companies
acceptable to the Majority Lenders.

          For purposes hereof, the term "Peril" shall mean, collectively, (i)

preserve and maintain, and will cause each of its Subsidiaries to preserve and
maintain, its legal existence and all of its rights, privileges and franchises
necessary or desirable in the normal conduct of its business, and will conduct
its business in a regular manner; PROVIDED that nothing herein shall prevent (i)
the merger and dissolution of any Subsidiary of the Company into the Company or
any Wholly-Owned Subsidiary of the Company so long as the Company or such
Wholly-Owned Subsidiary is the surviving corporation (and, if such Subsidiary is
not an Excluded Subsidiary prior to such merger or dissolution, the surviving
corporation (if not the Company) is not an Excluded Subsidiary and is a
Subsidiary Guarantor) (ii) the merger of any Subsidiary of the Company (a
"Merging Subsidiary") with any Person (other than the Company or a Wholly-Owned
Subsidiary of the Company) provided that (A) such merger is permitted under
Section 9.12(vi) hereof and (B) the surviving entity is either (x) a
Wholly-Owned Subsidiary (and, if such Merging Subsidiary is not an Excluded
Subsidiary prior to such merger, the surviving entity is not an Excluded
Subsidiary and is a Subsidiary Guarantor), or (y) an Excluded Subsidiary
(PROVIDED that such Merging Subsidiary is an Excluded Subsidiary prior to such
merger), or (iii) the abandonment of any right, privilege or franchise
(including any lease) not material in the aggregate to the business of the
Company and its Subsidiaries. Nothing in this Agreement shall, or shall be
deemed to, prohibit or restrict the merger of the Company with or into another
corporation for the sole purpose of changing the Company's domicile from
Pennsylvania to Delaware, so long as the surviving corporation of such merger,
if such surviving corporation is not the Company, shall expressly assume all of
the obligations of the Company under this Agreement and the other Basic
Documents to which it is a party and expressly agree to be bound by all other
provisions applicable to the Company under this Agreement and the other Basic
Documents to which it is a party in a manner reasonably satisfactory to the
Administrative Agent.

          (a) The Company will keep, and will cause each of its Subsidiaries to
     keep, all of its properties necessary in its business in good working order

     ordinary wear and tear excepted, and will permit representatives of the
     Lenders to inspect such properties and, upon reasonable notice and

<Page>

                                                                              70

     and records of the Company and any such Subsidiary.

     things necessary to preserve and keep in full force and effect all

     material to the conduct of the business of the Company and its Subsidiaries
     taken as a whole.

          9.06. COMPLIANCE WITH APPLICABLE LAWS. The Company will comply, and
     will cause each of its Subsidiaries to comply, with the requirements of all
     applicable laws, rules, regulations and orders of any governmental body or
     regulatory authority (including, without limitation, ERISA and all
     Environmental Laws), a breach of which would have a Material Adverse
     Effect, except where contested in good faith and by proper proceedings.

          9.07. LITIGATION. The Company will promptly give to the Administrative
     Agent (which shall promptly notify each Lender) notice in writing of (i)
     all judgments against it or any of its Subsidiaries (other than judgments
     covered by insurance) which in the aggregate exceed $10,000,000 and (ii)
     all litigation and of all proceedings of which it is aware before any
     courts, arbitrators or governmental or regulatory agencies affecting the
     Company or any of its Subsidiaries except litigation or proceedings which,

     have a Material Adverse Effect.

     its Subsidiaries to, create, incur or suffer to exist any Indebtedness
     except: (i) Indebtedness to the Lenders hereunder; (ii) the Indebtedness

or her services in such capacity; (b) the Company or a Subsidiary of the Company
may enter into any transaction with an Affiliate of the Company if the monetary
or business consideration arising therefrom would be substantially as
advantageous to the Company or such Subsidiary as the monetary or business
consideration which would obtain in a comparable arm's length transaction with a
Person similarly situated to the Company but not an Affiliate of the Company;
and (c) the Company may make Investments in Affiliates permitted by Section
9.14(ix) hereof and may create Residual Assurances for the benefit of an
Affiliate permitted by Section 9.23 hereof in either case in connection with the
construction and/or acquisition of records management facilities to be leased to
the Company or a Subsidiary, so long as, taking such transaction as a whole
(giving effect to such Investment or Residual Assurance, and the lease of such
facility to the Company or such Subsidiary) such Affiliate is not
disproportionately benefited.

          9.17. SUBORDINATED INDEBTEDNESS. The Company will not, nor will it
permit any of its Subsidiaries to, purchase, redeem, retire or otherwise acquire

other amount owing in respect of, any Subordinated Indebtedness, except for:

                (i) regularly scheduled payments or prepayments of principal and
          interest in respect thereof required pursuant to the instruments
          evidencing such Subordinated Indebtedness;

                (ii) so long as no Default has occurred and is continuing,
          scheduled payments of principal of (not to exceed $10,000,000 in the
          aggregate, excluding payments made in connection with that certain
          company named Datavault acquired by the Company in the United Kingdom)
          and interest on, and expenses and indemnities incurred in connection
          with, Seller Indebtedness; and

                (iii) any other purchase, redemption or retirement of
          Subordinated Indebtedness, so long as (i) no Default has occurred and
          is continuing and (ii) either (A) such other purchase, redemption or
          retirement is in connection with a refinancing of such Subordinated
          Indebtedness with the proceeds of, or in connection with an exchange
          of such Subordinated Indebtedness for a new series of, Senior
          Subordinated Debt issued within 60 days of the substantial completion
          of such purchase, redemption or retirement, or (B) after giving effect
          to such purchase, redemption or retirement, the ratio of Senior Debt

          Company to EBITDA for the four quarters then ended on a PRO FORMA
          basis, after giving effect to such purchase, redemption or retirement
          and any Stock Repurchase consummated on or prior to the date hereof,
          and to any borrowings to finance the same, as at the last day of the
          latest fiscal quarter is less than or equal to 1.5 to 1.

          (a) The Company will, and will cause each of its Subsidiaries to, take
such action from time to time as shall be necessary to ensure that the Company
and each of its Subsidiaries at all times owns (i) all of the issued and
outstanding shares of each class of Capital Stock of each of such Person's
Subsidiaries (other than, in each case, Capital Stock of Excluded Subsidiaries)
and (ii) more than 50% of the issued and outstanding shares of Capital Stock of

dispose of any shares of stock in any Subsidiary (other than an Excluded
Subsidiary) owned by them, nor permit any Subsidiary of the Company (other than
an Excluded Subsidiary) to issue any shares of Capital Stock of any class
whatsoever to any Person (other than to the Company or to another Wholly-Owned
Subsidiary or pursuant to Section 9.12 hereof). In the event that any such
additional shares of Capital Stock shall be issued by any Subsidiary of the
Company, or any Subsidiary shall be acquired, the Company agrees (so long as the
certificates evidencing such shares of stock are not subject to a lien permitted
under Section 9.13(vii) hereof, and in any event subject to clause (c) below)
forthwith to deliver to the Administrative Agent pursuant to the Security
Documents the certificates evidencing such shares of stock, accompanied by
undated stock powers executed in blank as well as, in accordance with the
Security Documents, promissory notes and intercompany notes specified as
Collateral as defined in the Security Documents and shall take such other action
as the Administrative Agent shall request to perfect the security interest
created therein pursuant to the Security Documents.

          (b) The Majority Lenders shall have the right from time to time to
require the Company, pursuant to a written request from the Administrative
Agent, to cause such Subsidiaries of the Company as may be specified in such
request (except for any SPE) to become parties to the Subsidiary Guaranty or to
execute and deliver such other guaranties, in form and substance satisfactory to
the Majority Lenders, guaranteeing payment of the Company's obligations
hereunder. Any such request shall be made by the Majority Lenders in the good
faith and reasonable exercise of their discretion. Within 30 days after any such
request, the Company shall, and shall cause the appropriate Subsidiaries of the
Company to, (i) execute and deliver to the Administrative Agent such number of
copies as the Administrative Agent may specify of documents creating such
guaranties and (ii) do all other things which may be necessary or which the
Administrative Agent may reasonably request in order to confer upon and confirm
to the Lenders the benefits of such security.

                (I) no Excluded Subsidiary shall be required to be or become a

          Subsidiary directly held by the Company or its Domestic Subsidiaries
          to the Administrative Agent under the Security Documents; and

                (III) the Company and its Subsidiaries shall not be required to
          pledge the stock of any other Excluded Subsidiary.

          (d) The Company will not permit any of its Subsidiaries (other than
Excluded Subsidiaries or any SPE acting pursuant to the terms of an Accounts
Receivable Financing permitted by the terms of this Agreement) to enter into,
after the date hereof, any indenture, agreement, instrument or other arrangement
(other than the Senior Subordinated Debt Documents) that, directly or
indirectly, prohibits or restrains, or has the effect of prohibiting or
restraining, or imposes materially adverse conditions upon, the incurrence or
payment of Indebtedness, the granting of Liens, the declaration or payment of
dividends, the making of loans, advances or Investments or the sale, assignment,
transfer or other disposition of Property.

          9.22. ENVIRONMENTAL MATTERS. The Company will promptly give to the

liability, obligation, remedial action, loss, damage, cost, expense, fine,
penalty or sanction resulting from any air emission, water discharge, noise

happening of any event involving the Release or cleanup of any Hazardous
Substance), (ii) any Release on such property or any part thereof in a quantity
that is reportable under any applicable Environmental Law, (iii) the

any of its Subsidiaries to, create, incur or suffer to exist any Residual
Assurances, except that (notwithstanding Sections 9.08 and 9.14) the Company may

any records management facility by any Affiliate of the Company so long as (a)
the maximum liability of the Company in respect of such Residual Assurance does
not exceed 15% of the fair market value (as determined in good faith by the
Board of Directors of the Company) of the completed records management facility,
and (b) the

                                                                              81

exceed $3,000,000 in the aggregate.

          9.24. INVESTMENTS IN EXCLUDED SUBSIDIARIES. The Company will not, and
will not permit any of its Subsidiaries (other than its Excluded Subsidiaries),
to make any advance, loan or other extension of credit to, or any other
Investment in, or Guarantee any Indebtedness of, any Excluded Subsidiary or any
other person organized outside of the United States or principally conducting
its business outside the United States if, after giving effect thereto, the
aggregate outstanding amount of such Investments and Guaranties (other than (a)
Guaranties permitted under clause (viii) of the definition of "Permitted
Indebtedness" in Section 1.01 hereof, (b) the Guaranties by the Company and its
Subsidiaries of (x) the Pierce 1998 Senior Notes and (y) Indebtedness under the

applicable exchange rate for any Investment or Guaranty or repayment thereof
determined by reference to the relevant Exchange Rate in effect at the time of
such Investment or Guaranty or repayment).

          9.25. HEDGING AGREEMENTS. The Company will not, and will not permit
any of its Subsidiaries to enter into any Hedging Agreement other than Hedging
Agreements entered into in the ordinary course of business, and not for
speculative purposes, to protect against changes in interest rates or foreign
exchange rates. Without limiting the generality of the foregoing, the Company
will not, and will not permit any of its Subsidiaries to, enter into any
derivatives or other transactions with any financial institution, commodities or

          (h) a final judgment or judgments by a court or courts (or a final

outstanding of and the accrued interest on the Loans, the Reimbursement
Obligations, and commitment fees and all other amounts payable hereunder and
under the Notes and the C$ Notes to be forthwith due and payable, whereupon such
amounts shall be and become immediately due and payable, without notice
(including, without limitation, notice of intent to accelerate), presentment,
demand, protest or other formalities of any kind, all of which are hereby
expressly waived by the Borrowers and the Canadian Borrower; PROVIDED that in
the case of the occurrence of an Event of Default with respect to the Company
referred to in clause (f) or (g) of this Section 10.01, the Commitments shall be
automatically terminated and the principal amount then outstanding of and the
accrued interest on the Loans, the

<Page>

                                                                              84

Reimbursement Obligations, and commitment fees and all other amounts payable
hereunder and under the Notes and the C$ Notes shall be and become automatically
and immediately due and payable, without notice (including, without limitation,
notice of intent to accelerate), presentment, demand, protest or other
formalities of any kind, all of which are hereby expressly waived by the
Company, the Borrowers and the Canadian Borrower.

                  In addition, upon the occurrence and during the continuance of
any Event of Default (if the Administrative Agent has declared the principal
amount then outstanding of, and accrued interest on, the Loans and all other
amounts payable by the Company, the Canadian Borrower or any other Borrower
hereunder and under the Notes and the C$ Notes to be due and payable), the
Company agrees that it shall, if requested by the Administrative Agent or the
Majority Lenders through the Administrative Agent (and, in the case of any Event
of Default referred to in clause (f) or (g) of this Section 10.01 with respect
to the Company or the other Borrowers or the Canadian Borrower, forthwith,
without any demand or the taking of any other action by the Administrative Agent
or such Lenders) provide cover for the Letter of Credit Liabilities by paying to
the Administrative Agent immediately available funds in an amount equal to the
then aggregate undrawn stated amount of all Letters of Credit, which funds shall
be held by the Administrative Agent in the Collateral Account as collateral
security in the first instance for the Letter of Credit Liabilities.

                  10.02. RATABLE TREATMENT OF LENDERS. In the event that the
Loans and the Reimbursement Obligations shall be declared or become immediately
due and payable on any date (the "ACCELERATION DATE") pursuant to Section 10.01
hereof, the Borrowers, the Canadian Borrower and the Revolving Lenders agree
that the outstanding Revolving Loans and Reimbursement Obligations and accrued
but unpaid interest thereon not denominated in Dollars shall be automatically
converted to Dollars on the Acceleration Date at the then applicable Exchange
Rate and any Reimbursement Obligation not denominated in Dollars thereafter
arising shall be automatically converted to Dollars on the date of the drawing
giving rise thereto under the relevant Letter of Credit at the then applicable
Exchange Rate. The Revolving Lenders hereby irrevocably agree for the benefit of
each other (and not for the benefit of the Borrowers, the Canadian Borrower or
the other Obligors) that, effective as of the Acceleration Date, each Revolving
Lender shall acquire participations in each then outstanding Revolving Loan and
Letter of Credit Liability in proportion to the aggregate Commitments of such
Revolving Lender to the aggregate Revolving Commitments of all the Revolving
Lenders, in each case determined immediately prior to the Acceleration Date
(such Revolving Lender's "PROPORTION"). On or promptly following the
Acceleration Date, the Administrative Agent shall determine for each Revolving
Lender the difference between (a) such Revolving Lender's Proportion of the
aggregate principal amount of the outstanding Revolving Loans and Reimbursement
Obligations on the Acceleration Date after giving effect to the automatic
conversion to Dollars and (b) the aggregate principal amount of such Revolving
Lender's actual outstanding Revolving Loans and Reimbursement Obligations on the
Acceleration Date after giving effect to the automatic conversions to Dollars.
Each Revolving Lender whose difference is positive shall make a payment which is
equal to such difference to the Administrative Agent in Dollars in immediately
available funds on a date set by the Administrative Agent promptly following the
Acceleration Date. The Administrative Agent shall distribute such payment to the
Revolving Lenders whose differences are negative, with such distribution to be
ratable based upon the respective amounts of such negative differences. On each

arises by virtue of a draw on a Letter of Credit, each Revolving Lender shall,
promptly after being notified thereof, make a payment to the Issuing Lender
equal to its Proportion of such Reimbursement Obligation. To the extent that any
Revolving Lender shall fail to pay any amount required to be paid pursuant to
this Section 10.02 on the due date therefor, such Revolving Lender shall pay
interest to the Administrative Agent for ratable distribution to the Revolving
Lenders or Issuing Lenders entitled thereto on such amount from and including
such due date to but excluding the date such payment is made at a rate per annum
equal to the Federal Funds Effective Rate, PROVIDED that if such Revolving
Lender shall fail to make such payment within three Business Days of such due
date, then, retroactively to the due date, such Revolving Lender shall be
obligated to pay interest on such amount at the ABR Rate.

          Section 11 THE ADMINISTRATIVE AGENT.

          11.01. APPOINTMENT POWERS AND IMMUNITIES. Each Lender hereby
irrevocably appoints and authorizes the Administrative Agent to act as its agent
hereunder and under the other Basic Documents with such powers as are
specifically delegated to the Administrative Agent by the terms hereof and
thereof, together with such other powers as are reasonably incidental thereto.
The Administrative Agent (which term as used in this Section 11 shall include
reference to its affiliates and its own and its affiliates' officers, directors,
employees and agents): (a) shall have no duties or responsibilities except those
expressly set forth in this Agreement and the other Basic Documents, and shall
not by reason of this Agreement or any other Basic Document be a trustee for any
Lender; (b) shall not be responsible to the Lenders for any recitals,
statements, representations or warranties contained in this Agreement or any
other Basic Document, or in any certificate or other document referred to or
provided for in, or received by any of them under, this Agreement or any other
Basic Document, or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Basic Document or
any other document referred to or provided for herein or therein or for any
failure by the Company, the Canadian Borrower, any other Borrower or any of the
Subsidiary Guarantors or any other Person to perform any of its obligations
hereunder or thereunder; (c) shall not be required to initiate or conduct any
litigation or collection proceedings hereunder or under any other Basic Document
except to the extent requested by the Majority Lenders; and (d) shall not be
responsible for any action taken or omitted to be taken by it hereunder or under
any other Basic Document or any other document or instrument referred to or
provided for herein or therein or in connection herewith or therewith, except
for its own gross negligence or willful misconduct. The Administrative Agent may
employ agents and attorneys-in-fact and shall not be responsible for the
negligence or misconduct of any such agents or attorneys-in-fact selected by it
with reasonable care.

          11.02. RELIANCE BY ADMINISTRATIVE AGENT. The Administrative Agent
shall be entitled to rely upon any certification, notice or other communication
(including any thereof by telephone, telex, telegram or cable) believed by it to
be genuine and correct and to have been signed or sent by or on behalf of the
proper Person or Persons, and upon advice and statements of legal counsel,
independent accountants and other experts selected by the Administrative Agent.
As to any matters not expressly provided for by this Agreement or any other
Basic Document, the Administrative Agent shall in all cases be fully protected
in acting, or in refraining from acting, hereunder and thereunder in accordance
with instructions signed by the

<Page>

                                                                              86

Majority Lenders and such instructions of the Majority Lenders and any action
taken or failure to act pursuant thereto shall be binding on all of the Lenders.

          11.03. DEFAULTS. The Administrative Agent shall not be deemed to have
knowledge of the occurrence of a Default (other than a Default of the type
specified in Section 10.01(a)) unless the Administrative Agent has received
notice from a Lender or the Company, the Canadian Borrower or any other Borrower
specifying such Default and stating that such notice is a "Notice of Default".
In the event that the Administrative Agent receives such a notice of the
occurrence of a Default, the Administrative Agent shall give prompt notice
thereof to the Lenders. The Administrative Agent shall (subject to Section 11.07
hereof) take such action with respect to such Default as shall be directed by
the Majority Lenders, provided that, unless and until the Administrative Agent
shall have received such directions, the Administrative Agent may (but shall not
be obligated to) take such action, or refrain from taking such action, with
respect to such Default as it shall deem advisable in the best interests of the
Lenders. The Administrative Agent shall deliver to the Lenders a copy of any
written declaration made pursuant to the second to last paragraph of Section
10.01 hereof.

          11.04. RIGHTS AS A LENDER. With respect to its Commitments and the
Loans made by it, the Administrative Agent in its capacity as a Lender hereunder
shall have the same rights and powers hereunder as any other Lender and may
exercise the same as though it were not acting as the Administrative Agent and
the term "Lender" or "Lenders" shall, unless the context otherwise indicates,
include the Administrative Agent in its individual capacity. The Administrative
Agent in its individual capacity may (without having to account therefor to any
Lender) accept deposits from, lend money to and generally engage in any kind of
banking, trust or other business with the Company, the Canadian Borrower, the
other Borrowers and the Subsidiary Guarantors (and their respective Affiliates)
as if it were not acting as the Administrative Agent, and the Administrative
Agent in its individual capacity may accept fees and other consideration from
the Company, the Canadian Borrower or any other Borrower (in addition to the
agency fees and arrangement fees heretofore agreed to between the Company or the
Canadian Borrower and the Administrative Agent) for services in connection with
this Agreement or otherwise without having to account for the same to the
Lenders.

          11.05. INDEMNIFICATION. The Lenders agree to indemnify the
Administrative Agent (to the extent not reimbursed under Section 12.03 or 12.04
hereof, but without limiting the obligations of the Company under said Sections
12.03 and 12.04), ratably in accordance with the principal amount of their
respective Loans and Reimbursement Obligations outstanding, or if no Loans or
Reimbursement Obligations are outstanding, ratably in accordance with their
respective Commitments, for any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind and nature whatsoever which may be imposed on, incurred by or
asserted against the Administrative Agent in any way relating to or arising out
of this Agreement or any other Basic Document or any other documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby (including, without limitation, the costs and
expenses which the Company is obligated to pay under Sections 12.03 and 12.04
hereof but excluding, unless a Default has occurred and is continuing, normal
administrative costs and expenses incident to the performance of its agency
duties hereunder) or the enforcement of any of the terms hereof or thereof or of
any such other

<Page>

                                                                              87

documents, PROVIDED, that no Lender shall be liable for any of the foregoing to
the extent they arise from the gross negligence or willful misconduct of the
party to be indemnified.

          11.06. NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER LENDERS. Each
Lender agrees that it has, independently and without reliance on the
Administrative Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own credit analysis of the
Company and the Canadian Borrower and decision to enter into this Agreement and
that it will, independently and without reliance upon the Administrative Agent
or any other Lender, and based on such documents and information as it shall
deem appropriate at the time, continue to make its own analysis and decisions in
taking or not taking action under this Agreement or any of the other Basic
Documents. The Administrative Agent shall not be required to keep itself
informed as to the performance or observance by the Company, the Canadian
Borrower, the other Borrowers and the Subsidiary Guarantors of this Agreement or
any of the other Basic Documents or any other document referred to or provided
for herein or therein or to inspect the properties or books of the Company, the
Canadian Borrower, any other Borrower or any of the Subsidiary Guarantors.
Except for notices, reports and other documents and information expressly
required to be furnished to the Lenders by the Administrative Agent hereunder or
the other Basic Documents, the Administrative Agent shall not have any duty or
responsibility to provide any Lender with any credit or other information
concerning the affairs, financial condition or business of the Company, the
Canadian Borrower, any other Borrower or any of the Subsidiary Guarantors (or
any of their affiliates) which may come into the possession of the
Administrative Agent.

          11.07. FAILURE TO ACT. Except for action expressly required of the
Administrative Agent hereunder and under the other Basic Documents, the
Administrative Agent shall in all cases be fully justified in failing or
refusing to act hereunder and thereunder unless it shall receive further
assurances to its satisfaction by the Lenders of their indemnification
obligations under Section 11.05 hereof against any and all liability and expense
which may be incurred by it by reason of taking or continuing to take any such
action.

          11.08. RESIGNATION OR REMOVAL OF ADMINISTRATIVE AGENT. Subject to the
appointment and acceptance of a successor Administrative Agent as provided
below, the Administrative Agent may resign at any time by giving notice thereof
to the Lenders and the Company and the Administrative Agent may be removed at
any time with or without cause by the Majority Lenders. Upon any such
resignation or removal the Majority Lenders shall have the right to appoint a
successor Administrative Agent reasonably acceptable to the Company. Upon any
such resignation or removal, the Administrative Agent that resigned or was
removed shall, to the extent that its annual agency fee was paid in advance, pay
to the Company an amount equal to such fee multiplied by a fraction the
numerator of which shall be the number of days remaining on the date of such
resignation or removal until the next anniversary of the Effective Date, and the
denominator of which shall be 365. If no successor Administrative Agent shall
have been so appointed by the Majority Lenders and shall have accepted such
appointment within 30 days after the retiring Administrative Agent's giving of
notice of resignation or the Majority Lenders' removal of the retiring
Administrative Agent (the "Notice Date"), then the retiring Administrative Agent
may, on behalf of the Lenders, appoint a successor Administrative Agent
reasonably acceptable to the Company. Any successor Administrative Agent shall
be (i) a Lender or (ii) if no Lender has accepted such appointment within 30
days after the Notice Date, a

                                                                              88

bank which has an office in New York, New York with a combined capital and
surplus of at least $250,000,000. Upon the acceptance of any appointment as
Administrative Agent hereunder by a successor Administrative Agent, such
successor Administrative Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder. After any retiring Administrative Agent's resignation
or removal hereunder as Administrative Agent, the provisions of this Section 11
shall continue in effect for its benefit in respect of any actions taken or
omitted to be taken by it while it was acting as the Administrative Agent.

          11.09. CONSENTS UNDER BASIC DOCUMENTS. Without the prior written
consent of the Majority Lenders, the Administrative Agent will not consent to
any modification, supplement or waiver under any of the Basic Documents or any
of the other documents described in Section 9.20 hereof.

          11.10. COLLATERAL SUB-AGENTS. Each Lender by its execution and
delivery of this Agreement agrees, as contemplated by the Security Documents,
that, in the event it shall hold any Liquid Investments referred to therein,
such Liquid Investments shall be held in the name and under the control of such
Lender and such Lender shall hold such Liquid Investments as a collateral
sub-agent for the Administrative Agent thereunder.

          11.11. MULTI-CURRENCY PAYMENT AGENT AND CANADIAN ADMINISTRATIVE AGENT.
The Multi-Currency Payment Agent referred to herein and the Canadian
Administrative Agent referred to in Annex A hereto shall be deemed to be
sub-agents of the Administrative Agent for all purposes of this Agreement and
entitled to the benefits of this Section 11.

          11.12. ADDITIONAL MINISTERIAL POWERS OF THE AGENTS. The Administrative
Agent is hereby irrevocably authorized by each of the Lenders to execute any
document creating any Lien and to release any Lien covering any asset of the
Company or any of its Subsidiaries (including, without limitation, any
Facilities, accounts receivable or inventory) that is the subject of a
disposition, sale or assignment which is permitted under this Agreement.

          Section 12 MISCELLANEOUS.

          12.01. WAIVER. No failure on the part of the Administrative Agent or
any Lender to exercise and no delay in exercising, and no course of dealing with
respect to, any right, power or privilege under any Basic Document shall operate
as a waiver thereof, nor shall any single or partial exercise of any right,
power or privilege thereunder preclude any other or further exercise thereof or
the exercise of any other right, power or privilege. The remedies provided in
the Basic Documents are cumulative and not exclusive of any remedies provided by
law.

          12.02. NOTICES. All notices and other communications provided for

          12.03. EXPENSES ETC. The Company agrees to pay or reimburse each of

Agent, the Canadian Administrative Agent, the Lenders and each affiliate thereof

Loan by any Lender hereunder or (ii) breach by the Company, the Canadian
Borrower or any other Borrower of this Agreement or any other Basic Document or
(iii) the Pierce Merger or (iv) any Environmental Liabilities (whether known or
unknown) or (v) any investigation, litigation or other proceeding (including any

Company shall reimburse the Administrative Agent, the Canadian Administrative

(including legal fees) incurred in connection with any such investigation or

this Agreement or the Notes or the C$ Notes, nor any consent to any departure by
the Company, the Canadian Borrower or any other Borrower therefrom, shall in any

<Page>

                                                                              90

which given; PROVIDED that no such change, waiver, discharge or termination
shall, without the consent of each Lender (other than a defaulting Lender)
directly affected thereby, (i) extend the Commitment Termination Date (it being
understood that any waiver of any prepayment of, or the method of application of
any prepayment to the amortization of, Loans shall not constitute any such
extension), or extend the stated maturity of any Letter of Credit beyond the
Commitment Termination Date, or extend the scheduled date of any payment of
principal of any Term Loan, or reduce the rate or extend the time of payment of
interest (other than as a result of waiving the applicability of any
post-default increase in interest rates) or fees, or reduce the principal amount
thereof, or increase any Commitment of any Lender over the amount thereof then
in effect (it being understood that a waiver of any Default or Event of Default
or of a mandatory reduction in the Commitments shall not constitute a change in
the terms of a Commitment of a Lender), (ii) amend, modify or waive any
provision of this Section 12.05, (iii) reduce the percentage specified in, or
(except to give effect to any additional facilities hereunder) otherwise modify,

their obligations under the Subsidiary Guaranty. Notwithstanding anything in
this Section 12.05 to the contrary, no amendment, waiver or consent shall be

Agent or (y) with respect to Annex A hereto without the consent of the Canadian
Borrower.

          12.06. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon
and inure to the benefit of the parties hereto and their respective successors
and assigns except that the Company, the Canadian Borrower and the other
Borrowers may not assign their rights or obligations hereunder or under the
Notes or the C$ Notes without the prior written consent of all of the Lenders.
Each Lender may assign all or a portion of its rights and obligations under this
Agreement and the Notes and the C$ Notes (i) to any affiliate thereof
(including, without limitation, (x) any entity (whether a corporation,
partnership, trust or otherwise) that is engaged in making, purchasing, holding
or otherwise investing in bank loans and similar lines of credit in the ordinary
course of its business and is administered or managed by a Lender or an
affiliate of such Lender and (y) with respect to any Lender that is a fund which
invests in bank loans and similar extensions of credit, any other fund that
invests in bank loans and similar extensions of credit and is managed by the
same investment advisor as such Lender or by an affiliate of such investment
advisor), (ii) to any other Lender or (iii) with the consent of the
Administrative Agent, of the Issuing Bank or the Canadian Issuing Bank (to the
extent that the rights and obligations assigned include obligations in respect
of the US$ Commitments, Multi-Currency Commitments or Canadian Commitments, as
the case may be) and of the Company (provided, that the consent of the Company
shall not be required if an Event of Default hereunder shall have occurred and
be continuing), which consents shall not be unreasonably withheld or delayed, to
any other bank or financial institution (it being understood that, in the case
of the Canadian Issuing Bank, it shall not be unreasonable to withhold consent
in the case of any proposed assignment to any entity or entities rated below
BBB+ by Standard & Poor's, a Division of the McGraw-Hill Companies, Inc., or
other comparable rating by another comparable rating agency), PROVIDED that any
such partial assignment shall not, unless the Company and the Administrative
Agent otherwise agree, be less than $5,000,000 (or, in the case of Term Loans,

<Page>

                                                                              91

$1,000,000), or if the remainder of the Lender's Commitment or Term Loans is
less than $5,000,000, such lesser amount. Upon execution by the assignor and the
assignee of an instrument pursuant to which the assignee assumes such rights and
obligations, payment by such assignee to such assignor of an amount equal to the
purchase price agreed between such assignor and such assignee and delivery to
the Administrative Agent and the Company of an executed copy of such instrument
together with payment by such assignee to the Administrative Agent of a
processing fee of $2,500, such assignee shall have, to the extent of such
assignment (unless otherwise provided therein), the same rights and benefits as
it would have if it were a Lender hereunder and the assignor shall be, to the
extent of such assignment (unless otherwise provided therein), released from its
obligations under this Agreement. Each Lender may (without the consent of any
other party to this Agreement) sell participations in all or any part of any
Loan or Loans or any Commitment or Commitments made by it to another bank or
other entity, in which event the participant shall not have any rights under
this Agreement (except as provided in the next succeeding sentence hereof), or
in the case of a Loan, such Lender's Note or C$ Note (the participant's rights
against such Lender in respect of such participation to be those set forth in
the agreement executed by such Lender in favor of the participant relating
thereto, which agreement shall not give the participant the right to consent to
any modification, amendment or waiver other than one described in clause (i),
(ii), (iii),(iv), (v) or (vi) of Section 12.05 hereof). Each of the Company and
the Canadian Borrower agrees that each participant shall be entitled to the
benefits of Sections 5.07 and 6 of this Agreement and Section 3.8 of Annex A
hereto with respect to its participation; PROVIDED that no participant shall be
entitled to receive any greater amount pursuant to such Sections than the
transferor Lender would have been entitled to receive in respect of the amount
of the participation transferred by such transferor Lender to such participant
had no such transfer occurred. Each Lender may furnish any information
concerning the Company and its Subsidiaries in the possession of such Lender
from time to time to assignees and participants (including prospective assignees
and participants) which have agreed in writing to be bound by the provisions of
Section 12.07 hereof. The Administrative Agent and the Company may, for all
purposes of this Agreement, treat any Lender as the holder of any Note or C$
Note drawn to its order (and owner of the Loans evidenced thereby) until written
notice of assignment, participation or other transfer shall have been received
by them from such Lender.

          In addition to the assignments and participations permitted the
foregoing provisions of this Section 12.06, any Lender may (without notice to
the Company, the Canadian Borrower, any other Borrower, the Administrative
Agent, the Issuing Bank or any other Lender and without payment of any fee)
assign and pledge all or any portion of its Loans and its Notes (i) to any
Federal Reserve Bank as collateral security pursuant to Regulation A of the
Board of Governors of the Federal Reserve System and any Operating Circular
issued by such Federal Reserve Bank and (ii) with respect to any Lender which is
a fund, to its trustee or creditors in support of its obligations to its trustee
or creditors, and such Loans and Notes shall be fully transferable as provided
therein. No such assignment pursuant to the preceding sentence shall release the
assigning Lender from its obligations hereunder.

          12.07. CONFIDENTIALITY. Each Lender agrees to exercise all reasonable
efforts to keep any information delivered or made available by or on behalf of
the Company to it which has not been publicly disclosed confidential from anyone
other than persons employed or retained by such Lender who are or are expected
to become engaged in evaluating, approving, structuring or administering the
Loans; PROVIDED that nothing herein shall prevent any Lender

                                                                              92

from disclosing such information (i) to any other Lender, (ii) to the officers,
directors, employees, agents, attorneys and accountants of such Lender or its
affiliates who have a need to know such information in accordance with customary
banking practices and who receive such information having been made aware of the
restrictions set forth in this Section, (iii) upon the order of any court or
administrative agency, (iv) upon the request or demand of any regulatory agency
or authority having jurisdiction over such Lender, (v) to the extent reasonably
required in connection with any litigation to which the Administrative Agent,
any Lender, the Company, the Canadian Borrower, any other Borrower, any
Subsidiary Guarantor or their respective affiliates may be a party, (vi) to the
extent reasonably required in connection with the exercise of any remedy
hereunder, (vii) to such Lender's legal counsel and independent auditors, and
(viii) to any actual or proposed participant or assignee of all or part of its
rights hereunder which has agreed in writing to be bound by the provisions of
this Section 12.07.

          12.08. SURVIVAL. The obligations of the Company under Sections 6.01,
6.05, 6.06, 6.08, 6.09, 12.03 and 12.04 hereof and of the Canadian Borrower
under such Sections and Section 3.8 of Annex A hereto and the obligations of the
Lenders under Section 11.05 shall survive the repayment of the Loans and the
termination of the Commitments.

          12.09. CAPTIONS. Captions and section headings appearing herein are
included solely for convenience of reference and are not intended to affect the
interpretation of any provision of this Agreement.

          12.10. COUNTERPARTS; INTEGRATION. This Agreement may be executed in
any number of counterparts, all of which taken together shall constitute one and
the same instrument, and any of the parties hereto may execute this Agreement by
signing any such counterpart. This Agreement constitutes the entire agreement
and understanding among the parties hereto and supersedes any and all prior
agreements and understandings, oral and written, relating to the subject matter
hereof.

                      SECTION 2. THE CANADIAN COMMITMENTS

hereof, each Canadian Lender severally agrees to make revolving credit loans
(which shall be C$ Prime Loans) to, to accept and, at the option of the Canadian
Borrower, purchase Bankers' Acceptances from, and to issue letters of credit for
the account of, the Canadian Borrower from time to time during the Commitment
Period in an aggregate principal amount at any one time outstanding not to
exceed the lesser of (i) such Lender's Canadian Commitment and (ii) the
US$-Canadian Commitment of such Lender less the aggregate outstanding principal
amount of the US$-Canadian Loans of such Lender. During the Commitment Period,
the Canadian Borrower may use the Canadian Commitments by borrowing, prepaying
(other than Bankers' Acceptances) or repaying the C$ Prime Loans or Bankers'
Acceptances, in whole or in part, and reborrowing, all in accordance with the
terms and conditions hereof.

          2.2. PROCEDURE FOR C$ PRIME LOAN BORROWING. The Canadian Borrower may
borrow C$ Prime Loans during the Commitment Period on any Business Day (Canada),
provided that the Canadian Borrower shall give the Canadian Administrative Agent
irrevocable written or telephonic notice (in the case of telephonic notice, to
be promptly confirmed in writing) (which notice must be received by the Canadian
Administrative Agent prior to 10:00 A.M., Toronto time, one Business Day
(Canada) prior to the requested Borrowing Date (Canada)), specifying (a) the
amount to be borrowed and (b) the requested Borrowing Date (Canada). Each
borrowing of C$ Prime Loans shall be in an amount equal to C$300,000 or a whole
multiple of C$100,000 in excess thereof. Upon receipt of any such irrevocable
notice from the Canadian Borrower, the Canadian Administrative Agent shall
promptly notify each Canadian Lender thereof. Each Canadian Lender will make the
amount of its pro rata share of each such borrowing available to the Canadian
Administrative Agent for the account of the Canadian Borrower at the Canadian
Administrative Office prior to 11:00 A.M., Toronto time, on the Borrowing Date
(Canada) requested by the Canadian Borrower in funds immediately available to
the Canadian Administrative Agent. Such borrowing will then be made available on
such date to the Canadian Borrower by the Canadian Administrative Agent
crediting the account of the Canadian Borrower on the books of the Canadian
Administrative Office with the aggregate of the amounts made available to the
Canadian Administrative Agent by the Canadian Lenders and in like funds as
received by the Canadian Administrative Agent.

          (a) The Canadian Borrower may issue Bankers' Acceptances denominated
in C$, for acceptance and, at the Canadian Borrower's option, purchase by the
Canadian Lenders, each in accordance with the provisions of this subsection 2.3.

          (b) PROCEDURES.

          (1) NOTICE. The Canadian Borrower shall notify the Canadian

     case of telephonic notice, to be promptly confirmed in writing) by 10:00
     A.M., Toronto time, two Business Days (Canada) prior to the date of the
     relevant borrowing in respect of any borrowing by way of Bankers'
     Acceptances.

                                                                               7

          (2) MINIMUM BORROWING AMOUNT. Each borrowing by way of Bankers'
     Acceptances shall be in a minimum aggregate face amount of C$1,000,000 or a
     whole multiple of C$100,000 in excess thereof.

          (3) FACE AMOUNTS. The face amount of each Bankers' Acceptance shall be
     C$100,000 or any whole multiple thereof.

          (4) TERM. Bankers' Acceptances shall be issued and shall mature on a
     Business Day (Canada). Each Bankers' Acceptance shall have a term of 30,
     60, 90 or 180 days (or such shorter or longer term as shall be agreed to by
     all of the Canadian Lenders), shall mature on or before the Commitment
     Termination Date and shall be in form and substance reasonably satisfactory
     to each Canadian Lender.

          (5) BANKERS' ACCEPTANCES IN BLANK. To facilitate the acceptance of
     Bankers' Acceptances under this Agreement, the Canadian Borrower shall,
     from time to time as required, provide to the Canadian Administrative Agent
     Drafts duly executed and endorsed in blank by the Canadian Borrower in
     quantities sufficient for each Canadian Lender to fulfill its obligations
     hereunder. In addition, the Canadian Borrower hereby appoints each Canadian
     Lender as its attorney, with respect to Bankers' Acceptances for which the
     Canadian Borrower has provided a Bankers' Acceptance notice:

               (i) to complete and sign on behalf of the Canadian Borrower,
          either manually or by facsimile or mechanical signature, the Drafts to
          create the Bankers' Acceptances (with, in each Canadian Lender's
          discretion, the inscription "This is a depository bill subject to the
          Depository Bills and Notes Act (Canada)");

               (ii) after the acceptance thereof by any Canadian Lender, to
          endorse on behalf of the Canadian Borrower, either manually or by
          facsimile or mechanical signature, such Bankers' Acceptance in favor
          of the applicable purchaser or endorsee thereof including, in such
          Canadian Lender's discretion, such Canadian Lender or a clearing house
          (as defined by the Depository Bills and Notes Act (Canada));

               (iii) to deliver such Bankers' Acceptances to such purchaser or
          to deposit such Bankers' Acceptances with such clearing house; and

               (iv) to comply with the procedures and requirements established
          from time to time by such Canadian Lender or such clearing house in
          respect of the delivery, transfer and collection of bankers'
          acceptances and depository bills.

     The Canadian Borrower recognizes and agrees that all Bankers' Acceptances
     signed, endorsed, delivered or deposited on its behalf by a Canadian Lender
     shall bind the Canadian Borrower as fully and effectually as if signed in
     the handwriting of and duly issued, delivered or deposited by the proper
     signing officer of the Canadian Borrower. Each Canadian Lender is hereby
     authorized to accept such Drafts or issue such Bankers' Acceptances
     endorsed in blank in such face amounts as may be determined by such
     Canadian Lender in accordance with the terms of this Agreement, PROVIDED
     that the

<Page>

                                                                               8

     aggregate amount thereof is less than or equal to the aggregate amount of
     Bankers' Acceptances required to be accepted by such Canadian Lender. No
     Canadian Lender shall be responsible or liable for its failure to accept a
     Bankers' Acceptance if the cause of such failure is, in whole or in part,
     due to the failure of the Canadian Borrower to provide duly executed and
     endorsed Drafts to the Canadian Administrative Agent on a timely basis, nor
     shall any Canadian Lender be liable for any damage, loss or other claim
     arising by reason of any loss or improper use of any such instrument except
     loss or improper use arising by reason of the gross negligence or willful
     misconduct of such Canadian Lender, its officers, employees, agents or
     representatives. The Canadian Administrative Agent and each Canadian Lender
     shall exercise such care in the custody and safekeeping of Drafts as it
     would exercise in the custody and safekeeping of similar property owned by
     it. Each Canadian Lender will, upon the request of the Canadian Borrower,
     promptly advise the Canadian Borrower of the number and designation, if
     any, of Drafts then held by it for the Canadian Borrower. Each Canadian
     Lender shall maintain a record with respect to Drafts and Bankers'
     Acceptances (i) received by it from the Canadian Administrative Agent in
     blank hereunder, (ii) voided by it for any reason, (iii) accepted by it
     hereunder, (iv) purchased by it hereunder and (v) canceled at their
     respective maturities. Each Canadian Lender further agrees to retain such
     records in the manner and for the statutory periods provided in the various
     Canadian provincial or federal statutes and regulations which apply to such
     Canadian Lender.

          (6) EXECUTION OF BANKERS' ACCEPTANCES. Drafts of the Canadian Borrower
     to be accepted as Bankers' Acceptances hereunder shall be duly executed on
     behalf of the Canadian Borrower. Notwithstanding that any person whose
     signature appears on any Bankers' Acceptance as a signatory for the
     Canadian Borrower may no longer be an authorized signatory for the Canadian
     Borrower at the date of issuance of a Bankers' Acceptance, 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
     Bankers' Acceptance so signed shall be binding on the Canadian Borrower.

          (7) ISSUANCE OF BANKERS' ACCEPTANCES. Promptly following receipt of a
     notice of borrowing by way of Bankers' Acceptances, the Canadian
     Administrative Agent shall so advise the Canadian Lenders and shall advise
     each Canadian Lender of the face amount of each Draft to be accepted by it
     and the term thereof. The aggregate face amount of Drafts to be accepted by
     a Canadian Lender shall be determined by the Canadian Administrative Agent
     on a pro rata basis by reference to the respective Canadian Commitments of
     the Canadian Lenders, except that, if the face amount of a Draft which
     would otherwise be accepted by a Canadian Lender would not be C$100,000 or
     a whole multiple thereof, such face amount shall be increased or reduced by
     the Canadian Administrative Agent in its sole and unfettered discretion to
     the nearest whole multiple of C$100,000.

          (8) ACCEPTANCE OF BANKERS' ACCEPTANCES. Each Draft to be accepted by a
     Canadian Lender shall be accepted at such Canadian Lender's Canadian
     Lending Office.

          (9) PURCHASE OF BANKERS' ACCEPTANCES. Each Canadian Lender shall be
     required to purchase (subject to the commercial availability of a resale
     market in the case of

<Page>

                                                                               9

     Bankers' Acceptances with a term of approximately 30, 60, 90 or 180 days,
     as the case may be) from the Canadian Borrower on the Borrowing Date
     (Canada), at the Applicable BA Discount Rate, the Bankers' Acceptances
     accepted by it on such date and to provide to the Canadian Administrative
     Agent the BA Discount Proceeds thereof not later than 12:00 Noon, Toronto
     time, on such Borrowing Date (Canada) for the account of the Canadian
     Borrower. The Acceptance Fee payable by the Canadian Borrower to such
     Canadian Lender under subsection 2.3(e) in respect of each Bankers'
     Acceptance accepted and purchased by such Canadian Lender from the Canadian
     Borrower shall be set off against the BA Discount Proceeds payable by such
     Canadian Lender under this subsection 2.3(b)(9). Not later than 2:00 P.M.,
     Toronto time, on such Borrowing Date (Canada), the Canadian Administrative
     Agent shall make such BA Discount Proceeds available to the Canadian
     Borrower by crediting the account of the Canadian Borrower on the books of
     the Canadian Administrative Office with the aggregate of the amounts made
     available to the Canadian Administrative Agent by the Canadian Lenders and
     in like funds as received by the Canadian Administrative Agent.

          (10) SALE OF BANKERS' ACCEPTANCES. Each Canadian Lender may at any
     time and from time to time hold, sell, rediscount or otherwise dispose of
     any or all Bankers' Acceptances accepted and purchased by it.

          (11) WAIVER OF PRESENTMENT AND OTHER CONDITIONS. To the extent
     permitted by applicable law, the Canadian Borrower waives presentment for
     payment and any other defense to payment of any amounts due to a Canadian
     Lender in respect of a Bankers' Acceptance accepted by it pursuant to this
     Agreement which might exist solely by reason of such Bankers' Acceptance
     being held, at the maturity thereof, by such Canadian Lender in its own
     right, and the Canadian Borrower agrees not to claim any days of grace if
     such Canadian Lender as holder sues the Canadian Borrower on the Bankers'
     Acceptances for payment of the amount payable by the Canadian Borrower
     thereunder.

          (c) The Canadian Borrower shall reimburse a Canadian Lender for, and
there shall become due and payable at 10:00 A.M., Toronto time, on the maturity
date for each Bankers' Acceptance, an amount in Canadian Dollars in same day
funds equal to the face amount of such Bankers' Acceptance. The Canadian
Borrower shall make each such reimbursement payment (i) by causing any proceeds
of a Refunding Bankers' Acceptance (as defined in subsection 2.3(d) below)
issued in accordance with subsection 2.3(d) or conversion of such Bankers'
Acceptance in accordance with subsection 2.4 to be applied in reduction of such
reimbursement payment; and (ii) by depositing the amount of such reimbursement
payment (or any portion thereof remaining unpaid after application of any
proceeds referred to in clause (i)) with the Canadian Administrative Office in
accordance with subsection 3.7. The Canadian Borrower's payment in accordance
with this subsection shall satisfy its obligations under any Bankers' Acceptance
to which it relates, and the Canadian Lender which has accepted such Bankers'
Acceptance shall thereafter be solely responsible for the payment of such
Bankers' Acceptance.

          (d) The Canadian Borrower shall give irrevocable written or telephonic
notice (in the case of telephonic notice, to be promptly confirmed in writing)
(or such other method of notification as may be agreed upon between the Canadian

                                                                              10

Canadian Borrower) to the Canadian Administrative Agent at or before 10:00 A.M.,
Toronto time, two Business Days (Canada) prior to the maturity date of each
Bankers' Acceptance of the Canadian Borrower's intention to issue a Bankers'
Acceptance on such maturity date (a "REFUNDING BANKERS' ACCEPTANCE") to provide
for the payment of such maturing Bankers' Acceptance (it being understood that
payments by the Canadian Borrower and fundings by the Canadian Lenders in
respect of each maturing Bankers' Acceptance and the related Refunding Bankers'
Acceptance shall be made on a net basis reflecting the difference between the
face amount of such maturing Bankers' Acceptance and the BA Discount Proceeds
(net of the applicable Acceptance Fee) of such Refunding Bankers' Acceptance).
If the Canadian Borrower fails to give such notice or does not have sufficient
funds on deposit in the amount of reimbursement payment in accordance with
subsection 2.3(c)(ii), the Canadian Borrower shall be deemed to have requested
that such maturing Bankers' Acceptances be repaid with the proceeds of C$ Prime
Loans (without any requirement to give notice with respect thereto), commencing
on the maturity date of such maturing Bankers' Acceptances.

          (e) An Acceptance Fee shall be payable by the Canadian Borrower to
each Canadian Lender in advance (in the manner specified in subsection 2.3(b)(9)
hereof) upon the issuance of a Bankers' Acceptance to be accepted by such
Canadian Lender calculated at the rate per annum equal to the Applicable Margin
for Canadian Borrowing, such Acceptance Fee to be calculated on the face amount
of such Bankers' Acceptance and to be computed on the basis of the number of
days in the term of such Bankers' Acceptance and a year of 365 days.

          (f) Upon the occurrence of any Event of Default which is continuing,
the Canadian Borrower shall, forthwith, without any demand or the taking of any
action by the Canadian Administrative Agent, provide cover for all outstanding
Bankers' Acceptances by paying to the Canadian Administrative Agent immediately
available funds in an amount equal to the then aggregate face amount of all
outstanding Bankers' Acceptances, which funds shall be held by the Canadian
Administrative Agent in an account as collateral security, and in addition to
any other rights or remedies of any Canadian Lender and the Canadian
Administrative Agent hereunder, any Canadian Lender or the Canadian
Administrative Agent (or such alternate arrangement as may be agreed upon by the
Canadian Borrower and such Canadian Lender or the Canadian Administrative Agent,
as applicable) shall be entitled to deposit and retain in an account to be
maintained by the Canadian Administrative Agent (bearing interest at the
Canadian Administrative Agent's rates as may be applicable in respect of other
deposits of similar amounts for similar terms), for the ratable benefit of the
Canadian Lenders, amounts which are received by such Canadian Lender or the
Canadian Administrative Agent from the Canadian Borrower hereunder or as
proceeds of the exercise of any rights or remedies of any Canadian Lender or the
Canadian Administrative Agent hereunder against the Canadian Borrower, to the
extent such amounts may be required to satisfy any contingent or unmatured
obligations or liabilities of the Canadian Borrower to the Canadian Lenders or
the Canadian Administrative Agent, or any of them hereunder.

          2.4. CONVERSION OPTION. Subject to the provisions of this Agreement,
the Canadian Borrower may, prior to the Commitment Termination Date, effective
on any Business Day (Canada), convert, in whole or in part, C$ Prime Loans into
Bankers' Acceptances or vice versa upon giving to the Canadian Administrative
Agent prior irrevocable written or telephonic notice (in the case of telephonic
notice, to be promptly confirmed in writing) within the notice

<Page>

                                                                              11

period and in the form which would be required to be given to the Canadian
Administrative Agent in respect of the category of C$ Loan into which the
outstanding C$ Loan is to be converted in accordance with the provisions of
subsection 2.2 or 2.3, as applicable, PROVIDED that:

          (a)  no C$ Prime Loan may be converted into a Bankers' Acceptance when
               any Event of Default has occurred and is continuing;

          (b)  each conversion to Bankers' Acceptances shall be for an aggregate
               amount of C$1,000,000 (and whole multiples of C$100,000 in excess
               thereof), and each conversion to C$ Prime Loans shall be in a
               minimum aggregate amount of C$300,000; and

          (c)  Bankers' Acceptances may be converted only on the maturity date
               of such Bankers' Acceptances and, PROVIDED that, if less than all
               Bankers' Acceptances are converted, then after such conversion
               not less than C$1,000,000 (and whole multiples of C$100,000 in
               excess thereof) shall remain as Bankers' Acceptances.

          2.5. CIRCUMSTANCES MAKING BANKERS' ACCEPTANCES UNAVAILABLE.

          (a) If the Canadian Administrative Agent determines in good faith,
which determination shall be final, conclusive and binding upon the Canadian
Borrower, and notifies the Canadian Borrower that, by reason of circumstances
affecting the money market, there is no market for Bankers' Acceptances, then:

          (i) the right of the Canadian Borrower to request a borrowing by way
     of Bankers' Acceptance shall be suspended until the Canadian Administrative
     Agent determines that the circumstances causing such suspension no longer
     exist and the Canadian Administrative Agent so notifies the Canadian
     Borrower; and

          (ii) any notice relating to a borrowing by way of Bankers' Acceptance
     which is outstanding at such time shall be deemed to be a notice requesting
     a borrowing by way of C$ Prime Loans (all as if it were a notice given
     pursuant to subsection 2.2).

          (b) The Canadian Administrative Agent shall promptly notify the
Canadian Borrower and the Canadian Lenders of the suspension of the Canadian
Borrower's right to request a borrowing by way of Bankers' Acceptance and of the
termination of such suspension.

          2.6. DESIGNATION OF BORROWINGS. On or prior to the date which is five
(5) Business Days (Canada) prior to the first day of each month, the US Borrower
and the Canadian Borrower shall give notice to each of the Canadian
Administrative Agent and the Administrative Agent, respectively, of the
aggregate Canadian Commitment and the aggregate US$-Canadian Commitment to be
available during such month (the "US-CANADIAN ALLOCATION"), and the Canadian
Administrative Agent and the Administrative Agent shall promptly notify the
Canadian Lenders and the US$-Canadian Lenders, respectively, thereof. With the
consent of each of the US$-Canadian Lenders, the Canadian Lenders, the
Administrative Agent and the Canadian Administrative Agent (as evidenced in a
manner satisfactory to the Administrative

<Page>

                                                                              12

Agent), the US Borrower and the Canadian Borrower may modify the then-current
US-Canadian Allocation for any period and subject to any notice as they may
request; and in the event of a failure by the US Borrower and the Canadian
Borrower to give a timely notice as to the US-Canadian Allocation for any month,
the US-Canadian Allocation for the immediately preceding month shall continue in
effect. The US Borrower and the Canadian Borrower agree that at no time during
such month shall the aggregate principal amount of the C$ Loans exceed the
aggregate Canadian Commitment specified in such notice, nor shall the aggregate
principal amount of the US$-Canadian Loans exceed the aggregate US$-Canadian
Commitment specified in such notice, and in no event shall the aggregate of the
Canadian Commitments and the US$-Canadian Commitments exceed US$50,000,000.

          2.7. FEES. The Canadian Borrower shall pay to the Canadian
Administrative Agent for the account of each Canadian Lender commitment fees in
Canadian Dollars on the daily average unused amount of such Canadian Lender's
Canadian Commitment (for which purpose, the aggregate amount of any Bankers'
Acceptance liabilities shall be deemed to be a PRO RATA (based on the Canadian
Commitments) use of each Canadian Lender's Canadian Commitment and the daily
average used amount of each Canadian Lender's Canadian Commitment shall be
determined after taking into account its outstanding US$-Canadian Loans) for the
period from the Closing Date to and including the earlier of the date the
Canadian Commitments are terminated and the Commitment Termination Date, at a
rate per annum equal to the Applicable Commitment Fee Rate in effect from time
to time. Accrued commitment fees under this subsection 2.7 shall be payable on
the Quarterly Dates and on the earlier of the date the Canadian Commitments are
terminated and the Scheduled Revolving Credit Commitment Termination Date. The
Canadian Borrower shall pay to the Canadian Administrative Agent on the Closing
Date syndication, agency and additional commitment fees in the amounts
heretofore mutually agreed in writing. The Canadian Borrower shall pay to the
Canadian Administrative Agent on the Closing Date and on each anniversary
thereof, so long as any of the Canadian Commitments are in effect and until
payment in full of all C$ Loans hereunder, all interest thereon and all other
amounts payable hereunder, and an annual agency fee in the amount heretofore
mutually agreed in writing.

          2.8. CANADIAN LETTERS OF CREDIT. Subject to the terms and conditions
of this Agreement, the Canadian Commitments may be utilized, upon the request of
the Canadian Borrower, in addition to the Loans provided for by subsection 2.2
hereof, by the issuance by the Canadian Issuing Bank of standby letters of
credit ("CANADIAN LETTERS OF CREDIT") for the account of the Canadian Borrower,
PROVIDED that in no event shall (i) the aggregate amount of all letter of credit
liabilities under the Canadian Commitments, together with the aggregate
outstanding principal amount of the C$ Loans, exceed the aggregate amount of the
Canadian Commitments as in effect from time to time, (ii) the aggregate
outstanding amount of all letter of credit liabilities under the Canadian
Commitments exceed $5,000,000 and (iii) the expiration date of any Canadian
Letter of Credit extend beyond the earlier of the Commitment Termination Date
and the date one year following the issuance of such Canadian Letter of Credit
(provided that any Canadian Letter of Credit with a one-year tenor may provide
for the renewal thereof for additional one-year periods, which periods shall in
any event not extend beyond the Commitment Termination Date). Prior to the
issuance of any Canadian Letter of Credit, the Administrative Agent shall have
first determined, and advised the relevant Canadian Issuing Bank, that the

<Page>

                                                                              13

requested amount of Canadian Letters of Credit shall be available under the
Canadian Commitments

          The following additional provisions shall apply to Canadian Letters of
Credit:

          (a) The Canadian Borrower shall give the Canadian Administrative Agent
at least three Business Days' irrevocable prior notice (effective upon receipt)
specifying the Business Day (which shall be no later than 5 days preceding the
Commitment Termination Date) on which each Canadian Letter of Credit is to be
issued and the account party or parties therefor and describing in reasonable
detail the proposed terms of such Canadian Letter of Credit (including the
beneficiary thereof) and the nature of the transactions or obligations proposed
to be supported thereby. Upon receipt of any such notice, the Canadian
Administrative Agent shall advise the Canadian Issuing Bank of the contents
thereof.

          (b) On each day during the period commencing with the issuance by the
Canadian Issuing Bank of any Canadian Letter of Credit and until such Canadian
Letter of Credit shall have expired or been terminated, the Canadian Commitment
of each Canadian Lender shall be deemed to be utilized for all purposes of this
Agreement in an amount equal to such Canadian Lender's C$ Commitment Percentage
of the then undrawn stated amount of such Canadian Letter of Credit. Each
Canadian Lender (other than the Canadian Issuing Bank) agrees that, upon the
issuance of any Canadian Letter of Credit hereunder, it shall automatically
acquire a participation in the Canadian Issuing Bank's rights and obligations
under such Canadian Letter of Credit in an amount equal to such Canadian
Lender's C$ Commitment Percentage of such rights and obligations, and each
Canadian Lender (other than the Canadian Issuing Bank) thereby shall
automatically absolutely, unconditionally and irrevocably assume, as primary
obligor and not as surety, and be unconditionally obligated to the Canadian
Issuing Bank to pay and discharge when due, its C$ Commitment Percentage of the
Canadian Issuing Bank's obligation to pay drawings under such Canadian Letter of
Credit.

          (c) Upon receipt from the beneficiary of any Canadian Letter of Credit
of any demand for payment under such Canadian Letter of Credit, the Canadian
Issuing Bank shall promptly notify the Canadian Borrower (through the Canadian
Administrative Agent) of the amount to be paid by the Canadian Issuing Bank as a
result of such demand and the date on which payment is to be made by the
Canadian Issuing Bank to such beneficiary in respect of such demand.
Notwithstanding the identity of the account party of any Canadian Letter of
Credit, the Canadian Borrower hereby unconditionally agrees to pay and reimburse
the Canadian Administrative Agent for account of the Canadian Issuing Bank for
the amount of each demand for payment under such Canadian Letter of Credit that
is in substantial compliance with the provisions of such Canadian Letter of
Credit at or prior to the date on which payment is to be made by the Canadian
Issuing Bank to the beneficiary thereunder, without presentment, demand, protest
or other formalities of any kind.

          (d) Forthwith upon its receipt of a notice referred to in paragraph
(c) of this Section 2.8, the Canadian Borrower shall advise the Canadian
Administrative Agent whether or not the Canadian Borrower intends to borrow
hereunder to finance its obligation to reimburse the Canadian Issuing Bank for
the amount of the related demand for payment and, if it does, submit a notice of
such borrowing as provided in Section 5.05 of the Credit Agreement.

                                                                              14

          (e) Each Canadian Lender shall pay to the Canadian Administrative
Agent for account of the Canadian Issuing Bank at the Canadian Administrative
Office in Canadian Dollars and in immediately available funds the amount of such
Canadian Lender's C$ Commitment Percentage of any payment under a Canadian
Letter of Credit upon notice by the Canadian Issuing Bank (through the Canadian
Administrative Agent) to such Canadian Lender requesting such payment and
specifying such amount. Each such Canadian Lender's obligation to make such
payment to the Canadian Administrative Agent for account of the Canadian Issuing
Bank under this paragraph (e), and the Canadian Issuing Bank's right to receive
the same, shall be absolute and unconditional and shall not be affected by any
circumstance whatsoever (other than gross negligence or wilful misconduct of the
Canadian Issuing Bank), including, without limitation, the failure of any other
Canadian Lender to make its payment under this paragraph (e), the financial
condition of the Company or the Canadian Borrower (or any other account party),
any failure to satisfy any condition precedent to any Loan, the existence of any
Default or the termination of the Commitments. Each such payment to the Canadian
Issuing Bank shall be made without any offset, abatement, withholding or
reduction whatsoever. If any Canadian Lender shall default in its obligation to
make any such payment to the Canadian Administrative Agent for account of the
Canadian Issuing Bank, for so long as such default shall continue the Canadian
Administrative Agent may at the request of the Canadian Issuing Bank withhold
from any payments received by the Canadian Administrative Agent under this
Agreement or any Note for account of such Canadian Lender the amount so in
default and, to the extent so withheld, pay the same to the Canadian Issuing
Bank in satisfaction of such defaulted obligation.

          (f) Upon the making of each payment by a Canadian Lender to the
Canadian Issuing Bank pursuant to paragraph (e) above in respect of any Canadian
Letter of Credit, such Canadian Lender shall, automatically and without any
further action on the part of the Canadian Administrative Agent, the Canadian
Issuing Bank or such Canadian Lender, acquire (i) a participation in an amount
equal to such payment in the Reimbursement Obligation owing to the Canadian
Issuing Bank hereunder and under the Canadian Letter of Credit Documents
relating to such Letter of Credit and (ii) a participation in a percentage equal
to such Canadian Lender's C$ Commitment Percentage in any interest or other
amounts payable by the Canadian Borrower hereunder and under such Letter of
Credit Documents in respect of such Reimbursement Obligation (other than the
commissions, charges, costs and expenses payable to the Canadian Issuing Bank
pursuant to paragraph (g) of this Section 2.8). Upon receipt by the Canadian
Issuing Bank from or for account of the Canadian Borrower of any payment in
respect of any Reimbursement Obligation or any such interest or other amount
(including by way of setoff or application of proceeds of any collateral
security) the Canadian Issuing Bank shall promptly pay to the Canadian
Administrative Agent for account of each Canadian Lender entitled thereto such
Canadian Lender's C$ Commitment Percentage of such payment, each such payment by
the Canadian Issuing Bank to be made in the same money and funds in which
received by the Canadian Issuing Bank. In the event any payment received by the
Canadian Issuing Bank and so paid to the Canadian Lenders hereunder is rescinded
or must otherwise be returned by the Canadian Issuing Bank, each Canadian Lender
shall, upon the request of the Canadian Issuing Bank (through the Canadian
Administrative Agent), repay to the Canadian Issuing Bank (through the Canadian
Administrative Agent) the amount of such payment paid to such Canadian Lender,
with interest at the rate specified in paragraph (j) of this Section 2.8.

                                                                              15

          (g) The Company shall pay to the Canadian Administrative Agent for
account of the Canadian Lenders (ratably in accordance with their respective C$
Commitment Percentages) a letter of credit fee in Canadian Dollars in respect of
each Canadian Letter of Credit in an amount equal to the Applicable L/C
Percentage of the daily average undrawn stated amount of such Canadian Letter of
Credit for the period from and including the date of issuance of such Canadian
Letter of Credit (i) in the case of a Canadian Letter of Credit that expires in
accordance with its terms, to and including such expiration date and (ii) in the
case of a Canadian Letter of Credit that is drawn in full or is otherwise
terminated other than on the stated expiration date of such Canadian Letter of
Credit, to but excluding the date such Canadian Letter of Credit is drawn in
full or is terminated (such fee to be non-refundable, to be paid in arrears on
each Quarterly Date and on the Commitment Termination Date and on the date of
expiry or termination or full utilization of such Canadian Letter of Credit and
to be calculated for any day after giving effect to any payments made under such
Canadian Letter of Credit on such day). In addition, the Company shall pay to
the Canadian Administrative Agent for account of the Canadian Issuing Bank a
fronting fee in Canadian Dollars in respect of each Canadian Letter of Credit in
an amount equal to 0.25% per annum of the daily average undrawn stated amount of
such Canadian Letter of Credit for the period from and including the date of
issuance of such Canadian Letter of Credit (i) in the case of a Canadian Letter
of Credit that expires in accordance with its terms, to and including such
expiration date and (ii) in the case of a Canadian Letter of Credit that is
drawn in full or is otherwise terminated other than on the stated expiration
date of such Canadian Letter of Credit, to but excluding the date such Canadian
Letter of Credit is drawn in full or is terminated (such fee to be
non-refundable, to be paid in arrears on each Quarterly Date and on the
Commitment Termination Date and to be calculated for any day after giving effect
to any payments made under such Canadian Letter of Credit on such day) plus all
commissions, charges, costs and expenses in the amounts customarily charged by
the Canadian Issuing Bank from time to time in like circumstances with respect
to the issuance of each Canadian Letter of Credit and drawings and other
transactions relating thereto.

          (h) Promptly following the end of each calendar month, the Canadian
Issuing Bank shall deliver (through the Canadian Administrative Agent) to each
Canadian Lender and the Canadian Borrower a notice describing the aggregate
amount of all Canadian Letters of Credit outstanding at the end of such month.
Upon the request of any Canadian Lender from time to time, the Canadian Issuing
Bank shall deliver any other information reasonably requested by such Canadian
Lender with respect to each Canadian Letter of Credit then outstanding.

          (i) The issuance by the Canadian Issuing Bank of each Canadian Letter
of Credit shall, in addition to the conditions precedent set forth in Section 7
of the Credit Agreement, be subject to the conditions precedent that (i) such
Canadian Letter of Credit shall be in such form, contain such terms and support
such transactions as shall be satisfactory to the Canadian Issuing Bank
consistent with its then current practices and procedures with respect to
letters of credit of the same type, (ii) such Canadian Letter of Credit shall be
denominated in Canadian Dollars and (iii) the Canadian Borrower shall have
executed and delivered such applications, agreements and other instruments
relating to such Canadian Letter of Credit as the Canadian Issuing Bank shall
have reasonably requested consistent with its then current practices and
procedures with respect to letters of credit of the same type, provided that in
the event of any conflict between any such application, agreement or other
instrument and the provisions of this Agreement or any Security Document, the
provisions of this Agreement and the Security Documents shall control.

          (j) To the extent that any Canadian Lender shall fail to pay any
amount required to be paid pursuant to paragraph (e) or (f) of this Section 2.8
on the due date therefor, such Canadian Lender shall pay interest to the
Canadian Issuing Bank (through the Canadian Administrative Agent) on such amount
from and including such due date to but excluding the date such payment is made
at the rate determined by the Canadian Administrative Agent in its discretion as
the appropriate rate for interbank settlements, PROVIDED that if such Canadian
Lender shall fail to make such payment to the Canadian Issuing Bank within three
Business Days of such due date, then, retroactively to the due date, such
Canadian Lender shall be obligated to pay interest on such amount at the rate
then payable by the Canadian Borrower on such amount.

          (k) The issuance by the Canadian Issuing Bank of any modification or
supplement to any Canadian Letter of Credit hereunder shall be subject to the
same conditions as are applicable under this Section 2.8 to the issuance of new
Canadian Letters of Credit, and no such modification or supplement shall be
issued hereunder unless either (i) the respective Canadian Letter of Credit
affected thereby would have complied with such conditions had it originally been
issued hereunder in such modified or supplemented form or (ii) each Canadian
Lender shall have consented thereto.

          The Company hereby indemnifies and holds harmless each Canadian Lender
(including the Canadian Issuing Bank and the Canadian Administrative Agent) from
and against any and all claims and damages, losses, liabilities, costs or
expenses that such Canadian Lender or the Canadian Administrative Agent may
incur (or that may be claimed against such Canadian Lender or the Canadian
Administrative Agent by any Person whatsoever) by reason of or in connection
with the execution and delivery or transfer of or payment or refusal to pay by
the Canadian Issuing Bank under any Canadian Letter of Credit; PROVIDED that the
Company shall not be required to indemnify any Canadian Lender or the Canadian
Administrative Agent for any claims, damages, losses, liabilities, costs or
expenses to the extent, but only to the extent, caused by (x) the willful
misconduct or gross negligence of the Canadian Issuing Bank in determining
whether a request presented under any Canadian Letter of Credit complied with
the terms of such Canadian Letter of Credit or (y) in the case of the Canadian
Issuing Bank, its failure to pay under any Canadian Letter of Credit after the
presentation to it of a request strictly complying with the terms and conditions
of such Canadian Letter of Credit. Nothing in this Section 2.8 is intended to
limit the other obligations of the Canadian Borrower, any Canadian Lender or the
Canadian Administrative Agent under this Agreement.

                         SECTION 3. GENERAL PROVISIONS

          3.1. REPAYMENT OF LOANS; EVIDENCE OF DEBT. The Canadian Borrower
hereby unconditionally promises to pay to the Canadian Administrative Agent for
the account of each Canadian Lender the then unpaid principal amount of each C$
Loan of such Canadian Lender on the Commitment Termination Date (or such earlier
date on which the C$ Loans become due and payable pursuant to Section 10 of the
Credit Agreement). The Canadian Borrower hereby further agrees to pay interest
on the unpaid principal amount of the C$ Loans from time to time outstanding
from the date hereof until payment in full thereof at the rates per annum, and
on the dates, set forth in subsection 3.5 hereof.

<Page>

                                                                              17

          3.2. C$ NOTES. The C$ Prime Loans made by each Canadian Lender under
its Canadian Commitment shall be evidenced by a single promissory note of the
Canadian Borrower (each, a "C$ NOTE") in substantially the form of Exhibit B to
this Annex A, dated the Closing Date, payable to such Canadian Lender in a
principal amount equal to such Canadian Commitment as in effect on the Closing
Date and otherwise duly completed. Each Canadian Lender is hereby authorized by
the Canadian Borrower to endorse on the schedule (or a continuation thereof)
attached to each C$ Note of such Canadian Lender, to the extent applicable, the
date and amount for each C$ Prime Loan made by such Canadian Lender to the
Canadian Borrower hereunder, and the date and amount of each payment or
prepayment of principal of such C$ Loan received by such Canadian Lender,
provided that any failure by such Canadian Lender to make any such endorsement
shall not affect the obligations of the Canadian Borrower under such C$ Note or
hereunder in respect of such C$ Prime Loan.

          3.3. TERMINATION OR REDUCTION OF COMMITMENTS.

          (a) The Canadian Commitments shall terminate on the Commitment
Termination Date.

          (b) The Canadian Borrower shall have the right to terminate or reduce
the unused Canadian Commitments at any time or from time to time to an amount
not less than the aggregate principal amount of the C$ Prime Loans and Bankers'
Acceptances outstanding, PROVIDED that (i) the Canadian Borrower shall give no
less than two Business Days' (Canada) notice of each such termination or
reduction to the Canadian Administrative Agent and (ii) each partial reduction
shall be in an aggregate amount at least equal to C$1,000,000 and, if greater,
in integral multiples of C$100,000. Any termination of the Canadian Commitments
shall be accompanied by prepayment in full of all C$ Prime Loans together with
accrued interest thereon to the date of such prepayment, and by cash
collateralization, but not prepayment, of the Bankers' Acceptances on terms
satisfactory to the Canadian Administrative Agent.

          3.4. OPTIONAL AND MANDATORY PREPAYMENTS.

          (a) OPTIONAL PREPAYMENTS. The Canadian Borrower shall have the right
to prepay the C$ Loans, in whole or in part, at any time or from time to time,
PROVIDED that the Canadian Borrower shall give the Canadian Administrative Agent
at least one Business Days' (Canada) irrevocable notice of each such prepayment
specifying the date and amount of such prepayment. Upon receipt of any such
notice the Canadian Administrative Agent shall promptly notify each Canadian
Lender thereof. If any such notice is given, the amount specified in such notice
shall be due and payable on the date specified therein, together with any
amounts payable pursuant to Section 12.04 of the Credit Agreement. Partial
prepayments shall be in an aggregate principal amount of C$1,000,000 or a whole
multiple of C$100,000 in excess thereof. Notwithstanding anything to the
contrary above, C$ Loans consisting of Bankers' Acceptances may not be prepaid
pursuant to this subsection.

          (b) MANDATORY PREPAYMENTS. (i) If, at any time during the Commitment
Period, the aggregate principal amount of C$ Loans outstanding with respect to
all Canadian Lenders exceeds the aggregate Canadian Commitments then in effect
by more than 5% of the aggregate principal amount of the Canadian Commitments
then in effect, the Canadian Borrower shall,

<Page>

                                                                              18

without notice or demand, immediately repay the C$ Loans (or, in the case of
Bankers' Acceptances, cash collateralize such Bankers' Acceptances) in an
aggregate principal amount equal to such excess, together with interest accrued
to the date of such payment or prepayment.

          (ii) If on any date, the Canadian Borrower or any Subsidiary of the
Canadian Borrower shall receive Net Cash Proceeds from any issuance subsequent
to the Closing Date of Indebtedness other than Indebtedness incurred pursuant to
Section 9.08 of the Credit Agreement (it being understood that this subsection
3.4(b) shall not constitute a waiver of any provision of said Section 9.08),
then the Canadian Borrower shall prepay the C$ Loans (or, in the case of
Bankers' Acceptances, cash collateralize such Bankers' Acceptances) in an amount
equal to such Net Cash Proceeds (less any prepayment on account of the receipt
of such Net Cash Proceeds under Section 3.02(b) of the Credit Agreement), but
the Canadian Commitments shall not be subject to automatic reduction.

          (c) APPLICATION OF MANDATORY PREPAYMENTS. To the extent that
prepayment is required to be made by the Canadian Borrower, such prepayment
shall be applied to reduce (ratably among the Canadian Lenders) such of the then
outstanding C$ Loans (or, in the case of Bankers' Acceptances, cash
collateralization of such Bankers' Acceptances on terms satisfactory to the
Canadian Administrative Agent, which cash collateral shall be invested in a
manner satisfactory to the Canadian Administrative Agent) as the Canadian
Borrower shall determine in its sole discretion.

          (d) Notwithstanding anything to the contrary contained above, (i) all
prepayments of C$ Loans shall be made in Canadian Dollars and (ii) all cash
collateralization of Bankers' Acceptances shall be made in Canadian Dollars.

          3.5. INTEREST RATES AND PAYMENT DATES.

          (a) Subject to subsection 3.5(b) below, each C$ Prime Loan shall bear
interest at a rate per annum equal to the C$ Prime Rate PLUS the Applicable
Margin for Canadian Borrowing.

          (b) The Canadian Borrower hereby promises to pay to the Canadian
Administrative Agent for account of each Canadian Lender interest at the
applicable Post-Default Rate (x) on any principal of any C$ Loan made by such
Canadian Lender and on any other amount payable by the Canadian Borrower
hereunder or under the C$ Note held by such Canadian Lender to or for account of
such Canadian Lender (but, if such amount is interest, only to the extent
legally enforceable), that shall not be paid in full when due (whether at stated
maturity, by acceleration, by mandatory prepayment or otherwise), for the period
from and including the due date thereof to but excluding the date the same is
paid in full and (y) during any period when an Event of Default shall have
occurred under Section 10.01(a) of the Credit Agreement and for so long as such
Event of Default shall be continuing, on any principal of any C$ Loan made by
such Canadian Lender.

          (c) Accrued interest on each C$ Prime Loan shall be calculated monthly
and payable quarterly in arrears, and in any event, upon the payment or
prepayment thereof, but only on the principal so paid or prepaid; PROVIDED that
interest payable after the occurrence of a

                                                                              19

Default at the Post-Default Rate shall be payable from time to time on demand of
the Canadian Administrative Agent or the Canadian Lenders having at least 51% of
the aggregate amount of the Canadian Commitments. Promptly after the
determination of any interest rate provided for herein or any change therein,
the Canadian Administrative Agent shall notify the Canadian Lenders and the
Canadian Borrower thereof.

          (d) Interest in respect of C$ Prime Loans (and all other amounts
denominated in C$) shall be payable in C$ and shall be payable based upon a year
of 365 days.

          (e) (i) If any provision of this Annex would obligate any party to the
Credit Agreement to make any payment of interest or other amount payable to any
Canadian Lender in an amount or calculated at a rate which would be prohibited
by law or would result in a receipt by such Canadian Lender of interest at a
criminal rate (as such terms are construed under the CRIMINAL CODE (Canada)),
then notwithstanding such provision, such amount or rate shall be deemed to have
been adjusted with retroactive effect to the maximum amount or rate of interest,
as the case may be, as would not be so prohibited by law or so result in a
receipt by such Canadian Lender of interest at a criminal rate, such adjustment
to be effected, to the extent necessary, as follows:

          (x)  first, by reducing the amount or rates of interest required to be
               paid under this subsection 3.5; and

          (y)  thereafter, by reducing any fees, commissions, premiums and other
               amounts which would constitute interest for purposes of Section
               347 of the CRIMINAL CODE (Canada).

          (ii) If, notwithstanding the provisions of clause (i) of this
subsection 3.5(e), and after giving effect to all adjustments contemplated
thereby, any Canadian Lender shall have received an amount in excess of the
maximum permitted by such clause, then the party having paid such amount shall
be entitled, by notice in writing to such Canadian Lender, to obtain
reimbursement from such Canadian Lender of an amount equal to such excess, and,
pending such reimbursement, such amount shall be deemed to be an amount payable
by such Canadian Lender to such party.

          (iii) Any amount or rate of interest referred to in this subsection
3.5(e) shall be determined in accordance with generally accepted actuarial
practices and principles as an effective annual rate of interest over the term
of any C$ Loan on the assumption that any charges, fees or expenses that fall
within the meaning of "interest" (as defined in the CRIMINAL CODE (Canada))
shall, if they relate to a specific period of time, be prorated over that period
of time and otherwise be prorated over the period from the Closing Date to the
Scheduled Revolving Credit Commitment Termination Date and, in the event of
dispute, a certificate of a Fellow of the Canadian Institute of Actuaries
appointed by the Canadian Administrative Agent shall be conclusive for the
purposes of such determination absent manifest error.

          3.6. COMPUTATION OF INTEREST AND FEES. For the purposes of the
INTEREST ACT (Canada), in any case in which an interest rate is stated in this
Agreement to be calculated on the basis of a year of 360 days or 365 days, as
the case may be, the yearly rate of interest to which

<Page>

                                                                              20

such interest rate is equivalent is equal to such interest rate multiplied by
the number of days in the year in which the relevant interest payment accrues
and divided by 360 or 365, respectively. In addition, the principles of deemed
investment of interest do not apply to any interest calculations under this
Agreement and the rates of interest stipulated in this Agreement are intended to
be nominal rates and not effective rates or yields.

          3.7. PRO RATA TREATMENT AND PAYMENTS.

          (a) Each borrowing by the Canadian Borrower from the Canadian Lenders
hereunder, each payment by the Canadian Borrower on account of any commitment
fee or Acceptance Fee hereunder and any reduction of the Canadian Commitments of
the Canadian Lenders shall be made pro rata according to the respective C$
Commitment Percentages. Each payment by the Canadian Borrower on account of
principal of and interest on the C$ Loans shall be made pro rata according to
the respective outstanding principal amounts of the relevant C$ Loans then held
by the relevant Canadian Lenders. All payments (including prepayments) to be
made by the Canadian Borrower hereunder, whether on account of principal,
interest, fees or otherwise, shall be made without set off or counterclaim and
shall be made prior to 11:00 A.M., Toronto time, on the due date thereof to the
Canadian Administrative Agent, for the account of the Canadian Lenders, at the
Canadian Administrative Office in C$ and in immediately available funds. The
Canadian Administrative Agent shall distribute such payments to the Canadian
Lenders promptly upon receipt in like funds as received, but the Canadian
Borrower shall have satisfied its payment obligation hereunder upon payment to
the Canadian Administrative Agent, regardless of whether such Canadian
Administrative Agent distributes such payments as required hereunder. If any
payment hereunder becomes due and payable on a day other than a Business Day
(Canada), such payment shall be extended to the next succeeding Business Day
(Canada), and, with respect to payments of principal, interest thereon shall be
payable at the then applicable rate during such extension.

          (b) Unless the Canadian Administrative Agent shall have received
notice from a Canadian Lender prior to 11:00 A.M., Toronto time, on any
Borrowing Date (Canada) that such Lender will not make available to the Canadian
Administrative Agent such Canadian Lender's share of the borrowing requested to
be made on such Borrowing Date (Canada), the Canadian Administrative Agent may
assume that such Canadian Lender has made its share of such borrowing available
to the Canadian Administrative Agent on such Borrowing Date (Canada), and the
Canadian Administrative Agent may, in reliance upon such assumption, make
available to the Canadian Borrower on such Borrowing Date (Canada) a
corresponding amount. If such amount is not so made available to the Canadian
Administrative Agent by such Canadian Lender on such Borrowing Date (Canada),
the Canadian Administrative Agent shall also be entitled to recover such amount
with interest thereon at the rate per annum applicable to the C$ Prime Rate
determined for such day PLUS 1%, on demand, from the relevant Canadian Lender.
Nothing contained in this subsection 3.7(b) shall relieve any Canadian Lender
which has failed to make available its share of any borrowing hereunder from its
obligation to do so in accordance with the terms hereof or prejudice any rights
which the Canadian Borrower may have against any Canadian Lender as a result of
any default by such Canadian Lender to make loans.

          (c) The failure of any Canadian Lender to make the C$ Loan to be made
by it on any Borrowing Date (Canada) shall not relieve any other Lender of its
obligation, if any,

<Page>

                                                                              21

hereunder to make its C$ Loan on such Borrowing Date (Canada), but no Lender
shall be responsible for the failure of any other Canadian Lender to make the C$
Loan to be made by such other Canadian Lender on such Borrowing Date (Canada).

          3.8. ADDITIONAL COSTS.

          (a) If the adoption of or any change in any Requirement of Law
regarding capital adequacy or in the interpretation or application thereof by
any Governmental Authority or compliance by any Canadian Lender or any
corporation controlling such Canadian Lender with any request or directive
regarding capital adequacy (whether or not having the force of law) from any
Governmental Authority made subsequent to the date hereof shall have the effect
of reducing the rate of return on such Canadian Lender's or such corporation's
capital as a consequence of its obligations hereunder to a level below that
which such Canadian Lender or such corporation could have achieved but for such
adoption, change or compliance (taking into consideration such Lender's or such
corporation's policies with respect to capital adequacy) by an amount deemed by
such Canadian Lender to be material, then from time to time, the Canadian
Borrower shall promptly pay to such Canadian Lender, upon written demand
therefor, such additional amount or amounts as will compensate such Canadian
Lender for such reduced rate of return. In determining such additional amounts,
each Canadian Lender will act reasonably and in good faith and will use
averaging and attribution methods which are reasonable and which will, to the
extent the reduced rate of return relates to such Canadian Lender's loans or
commitments in general and are not specifically attributable to C$ Loans or
Canadian Commitments hereunder, be calculated with respect to all loans or
commitments similar to the C$ Loans or Canadian Commitments made by such
Canadian Lender hereunder whether or not the loan documentation for such other
loans or commitments permits the Canadian Lender to charge the respective
borrower on a basis similar to that provided in this subsection 3.8.

          (b) If any Canadian Lender becomes entitled to claim any additional
amounts pursuant to this subsection, it shall promptly notify the Canadian
Borrower (with a copy to the Canadian Administrative Agent) of the event by
reason of which it has become so entitled. A certificate as to any additional
amounts payable pursuant to this subsection submitted by such Canadian Lender to
the Canadian Borrower (with a copy to the Canadian Administrative Agent),
showing in reasonable detail the basis for the calculation thereof, shall be
prima facie evidence of such additional amounts payable. The agreements in this
subsection shall survive the termination of the Credit Agreement and the payment
of the C$ Loans and all other amounts payable thereunder.

          3.9. TAXES. All payments made by the Canadian Borrower, the US
Borrower or any Subsidiary Guarantor in respect of amounts owing under this
Annex A and any C$ Notes shall be made free and clear of, and without deduction
or withholding for or on account of, any present or future income, stamp or
other taxes, levies, imposts, duties, charges, fees, deductions or withholdings,
now or hereafter imposed, levied, collected, withheld or assessed by any
Governmental Authority, excluding gross or net income or gross receipts taxes,
ad valorem taxes, personal property and/or sales taxes and franchise taxes
(imposed in lieu of net income taxes) imposed on the Canadian Administrative
Agent or any Canadian Lender as a result of a present or former connection
between the Canadian Administrative Agent or such Canadian Lender and the
jurisdiction of the Governmental Authority imposing such tax or any political

<Page>

                                                                              22

subdivision or taxing authority thereof or therein (other than any such
connection arising solely from the Canadian Administrative Agent or such
Canadian Lender having executed, delivered or performed its obligations or
received a payment under, or enforced, this Annex A or any C$ Note). If any such
non-excluded taxes, levies, imposts, duties, charges, fees deductions or
withholdings ("NON-EXCLUDED TAXES") are required to be withheld from any amounts
payable to the Canadian Administrative Agent or any Canadian Lender hereunder or
under any C$ Note, the amounts so payable to the Canadian Administrative Agent
or such Canadian Lender shall be increased to the extent necessary to yield to
the Canadian Administrative Agent or such Canadian Lender (after payment of all
Non-Excluded Taxes) interest or any such other amounts payable hereunder at the
rates or in the amounts specified in this Annex A, PROVIDED, HOWEVER, that
neither the Canadian Borrower, the US Borrower, nor any Subsidiary Guarantor
shall be required to increase any such amounts payable to the Canadian
Administrative Agent, any Canadian Lender or any holder of Bankers' Acceptances
if such increased amount arises as a result of the failure of such Canadian
Lender, the Canadian Administrative Agent or any holder of Bankers' Acceptances
to be a Person resident in Canada for the purposes of the INCOME TAX ACT
(Canada). The Canadian Borrower shall also indemnify the Canadian Administrative
Agent and each Canadian Lender on an after-tax basis for any additional taxes on
net income which the Canadian Administrative Agent or such Canadian Lender, as
the case may be, may be obligated to pay as a result of the receipt of
additional amounts under this subsection 3.9. Whenever any Non-Excluded Taxes
are payable by the Canadian Borrower, the US Borrower or any Subsidiary
Guarantor, as promptly as possible thereafter but in any event within 45 days
after the date of payment the Canadian Borrower, the US Borrower or such
Subsidiary Guarantor shall send to the Canadian Administrative Agent for its own
account or for the account of such Canadian Lender, as the case may be, a
certified copy of an original official receipt received by the Canadian
Borrower, the US Borrower or such Subsidiary Guarantor showing payment thereof.
If the Canadian Borrower, the US Borrower or any Subsidiary Guarantor fails to
pay any Non-Excluded Taxes when due to the appropriate taxing authority or fails
to remit to the Canadian Administrative Agent the required receipts or other
required documentary evidence, the Canadian Borrower, the US Borrower or such
Subsidiary Guarantor shall indemnify the Canadian Administrative Agent and the
Canadian Lenders for any incremental taxes, interest or penalties that may
become payable by the Canadian Administrative Agent or any Canadian Lender as a
result of any such failure. The agreements in this subsection shall survive the
termination of this Annex A and the payment of the C$ Loans and all other
amounts payable hereunder.

          3.10. SUBSTITUTION OF LENDER. If any Canadian Lender has demanded
compensation under subsection 3.8 of this Annex A, the Canadian Borrower shall
have the right, with the assistance of the Canadian Administrative Agent, to
seek a substitute bank or banks (which may be one or more of the Lenders)
satisfactory to the Canadian Borrower and the Canadian Administrative Agent to
purchase the C$ Notes and assume the Canadian Commitments of such Canadian
Lender. Any such Canadian Lender shall be obligated to sell the C$ Notes for
cash without recourse to such substitute bank or banks and to execute and
deliver an appropriately completed assignment and assumption agreement
reasonably satisfactory to the Canadian Administrative Agent and the Canadian
Borrower and any other document or perform any act reasonably necessary to
effect the assumption of the rights and obligations of such substitute bank or
banks.

Agreement or hereunder in respect of the C$ Prime Loans made by the Bank.
