     FOR VALUE RECEIVED, the undersigned HTM Holdings, Inc., a Delaware

forth on Schedule 1 hereto or its registered assigns (each, a "Payee"), on
demand at any time made by the Payees holding more than 50% of the aggregate
principal amount then outstanding hereunder, the principal sum set forth
opposite the name of such Payee on Schedule 1 hereto, together with interest of
(i) a lump sum of 3% of such principal amount accruing on the date hereof and

clear of and without deduction for any and all present or future Taxes. If the
Company shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder, (i) the sum payable shall be increased as much as shall
be necessary so that after making all required deductions (including deductions
applicable to additional sums payable hereunder) each Payee shall receive an
amount equal to the sum it would have received had no such deductions been made,
(ii) the Company shall make such deductions and (iii) the Company shall pay the
full amount deducted to the relevant taxing or other authority in accordance
with applicable law. Within thirty (30) days after the date of any payment of
Taxes, the Company shall furnish to each Payee the original or certified copy of
a receipt evidencing payment thereof. The Company shall indemnify and, within
ten (10) days of demand therefor, pay each Payee for the full amount of Taxes
(including any Taxes imposed by any jurisdiction on amounts payable hereunder)
paid by such Payee, and any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto, whether or not such Taxes
were correctly or legally asserted.

the meanings so defined.

     The Company hereby waives diligence, presentment, demand, protest and
notice of any kind whatsoever. The nonexercise by the holder of any of its
rights hereunder in any particular instance shall not constitute a waiver
thereof in that or any subsequent instance.

     This Note shall be construed in accordance with and governed by the laws of
The Commonwealth of Massachusetts without giving effect to principles of
conflicts of laws.

otherwise been made pursuant to Section 2.7(b), one of the events described in
Section 13(f) shall have occurred and be continuing with respect to the U.S.
Borrower, or if for any other reason, as determined by the Swing Line Lender in
its sole discretion, U.S. Revolving Credit Loans may not be made as contemplated

U.S. Revolving Credit Loan was to have been made pursuant to the notice referred

the sum of the aggregate principal amount of Swing Line Loans then outstanding
which were to have been repaid with such U.S. Revolving Credit Loans.

          (d)  Whenever, at any time after the Swing Line Lender has received
from any U.S. Revolving Credit Lender such Lender's Swing Line Participation
Amount, the Swing Line Lender receives any payment on account of the Swing Line
Loans, the Swing Line Lender will distribute to such Lender its Swing Line
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 Swing Line Loans then
due); provided, however, that in the event that such payment received by the

Swing Line Lender is required to be returned, such U.S. Revolving Credit Lender
will return to the Swing Line Lender any portion thereof previously distributed
to it by the Swing Line Lender.

          (e)  Each U.S. Revolving Credit Lender's obligation to make the U.S.

Attorney") authorizing each Canadian Revolving Credit Lender to draw Drafts on
--------
such Canadian Revolving Credit Lender on behalf of the Canadian Borrower and to
complete such Drafts in accordance with the Requests for Acceptances submitted
from time to time pursuant to Section 5.7(a).

          (c)  Each Request for Acceptances made by or on behalf of the Canadian
Borrower hereunder shall contain a request for Acceptances denominated in
Canadian Dollars and having an aggregate undiscounted face amount equal to
C$1,000,000 or a whole multiple of C$100,000 in excess thereof.  Each Acceptance
shall be dated the Borrowing Date specified in the Request for Acceptances with
respect thereto and shall be stated to mature on a Business Day which is
approximately 30, 60, 90 or 180 days after the date thereof (and, in any event,
prior to the Canadian Revolving Credit Termination Date).

          (d)  Not later than 12:00 Noon, Toronto time, on the Borrowing Date
specified in the relevant Request for Acceptances, and upon fulfillment of the
applicable conditions set forth in Section 9.2, each Canadian Revolving Credit
Lender will, in accordance with such Request for Acceptances, (i) sign each
Draft on behalf of the Canadian Borrower pursuant to the Power of Attorney, (ii)
complete the date, amount and maturity of each Draft to be accepted, (iii)
accept such Drafts and give notice to the Canadian Administrative Agent of such
acceptance and (iv) upon such acceptance, purchase such Acceptances to the
extent contemplated by Section 5.8. Alternatively, at the request of the
Canadian Administrative Agent, the Canadian Borrower shall deliver to the
Canadian Administrative Agent a "depository note" which complies with the
requirements of the Depository Bills and Notes Act (Canada), and consents to the
deposit of any Acceptance in the form of a depository note in the book-based
debt clearance system maintained by the Canadian Depository of Securities or
other recognized clearing house.  In such circumstances, the delivery of
Acceptances shall be governed by the clearance procedures established
thereunder.

          (e)  Each Canadian Revolving Credit Lender will 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 and will, upon request by the
Canadian Borrower, promptly advise the Canadian Borrower of the number and
designations, if any, of uncompleted Drafts held by it for the Canadian
Borrower.  The signature of any officer of the Canadian Borrower on a Draft may
be mechanically reproduced and Acceptance Notes bearing facsimile signatures
shall be binding upon the Canadian Borrower as if they had been manually signed.
Even if the individuals whose manual or facsimile signature appears on any
Acceptance or Acceptance Note no longer hold office at the date of signature, at
the date of its acceptance by the Lender or at any time after such date, any

Acceptance or Acceptance Note so signed shall be valid and binding upon the
Canadian Borrower.

          5.8  Discount of Acceptances.  (a)  Each Canadian Revolving Credit
               -----------------------
Lender hereby severally agrees, on the terms and subject to the conditions set
forth in this Agreement, to purchase or cause to be purchased Acceptances
created by it on the Borrowing Date with respect thereto at the applicable
Reference Discount Rate by making available to the Canadian Borrower an amount
in immediately available funds equal to the Acceptance Purchase Price in respect
thereof, and to notify the Canadian Administrative Agent that such Draft has
been accepted, discounted and purchased by such accepting Canadian Revolving
Credit Lender.

          (b)  In the event that the Canadian Borrower has made a Request for
Acceptances, then (i) prior to 11:00 A.M., Toronto time, on the Borrowing Date
with respect thereto, the Canadian Administrative Agent will notify the General
Administrative Agent, the Canadian Borrower and the Canadian Revolving Credit
Lenders of the applicable Reference Discount Rate for such Acceptances and the
corresponding Acceptance Purchase Price and (ii) each Canadian Revolving Credit
Lender shall make the Acceptance Purchase Price for such Acceptances discounted
by it available to the Canadian Administrative Agent, for the account of the
Canadian Borrower, at the Canadian Funding Office prior to 12:00 Noon, Toronto
time, on the Borrowing Date, in Canadian Dollars and in funds immediately
available to the Canadian Administrative Agent.  The proceeds of such purchase
will then be made available to the Canadian Borrower by the Canadian
Administrative Agent in like funds as received by the Canadian Administrative
Agent.

          (c)  Acceptances purchased or caused to be purchased by any Canadian
Revolving Credit Lender may be held by it for its own account until maturity or
sold by it at any time prior thereto in the relevant market therefor in Canada
in such Canadian Revolving Credit Lender's sole discretion.  The doctrine of
merger shall not apply with respect to any Acceptance held by a Lender at
maturity.

          5.9  Stamping Fees.  On the Borrowing Date with respect to each
               -------------
Acceptance, the Canadian Borrower shall pay to the Canadian Administrative
Agent, for the account of the Canadian Revolving Credit Lenders, a stamping fee
payable in Canadian Dollars at a rate per annum equal to the Applicable Margin
in effect on such Borrowing Date for Eurodollar Loans under the Canadian
Revolving Credit Facility, computed for the period from and including the
Borrowing Date with respect to such Acceptance to but not including the maturity
of such Acceptance, on the basis of a 365 or 366 -day year, as the case may be,
of the undiscounted face amount of such Acceptance.  On any Borrowing Date with
respect to an Acceptance, the Canadian Borrower hereby authorizes each Canadian
Revolving Credit Lender to net all amounts payable on such date by such Canadian
Revolving Credit Lender to the Canadian Administrative Agent for the account of
the Canadian Borrower, against all amounts payable on such date by the Canadian
Borrower to such Canadian Revolving Credit Lender in accordance with the
Canadian Administrative Agent's calculations.

          5.10 Acceptance Reimbursement Obligations.  (a)  The Canadian
               ------------------------------------
Borrower hereby unconditionally agrees to pay to the Canadian Administrative
Agent for the account of each Canadian Revolving Credit Lender, on the maturity
date (whether at stated maturity, by acceleration or otherwise) for each
Acceptance created by such Canadian Revolving Credit Lender for the account of
the Canadian Borrower, the aggregate undiscounted face amount of each such then-
maturing Acceptance.

          (b)  The obligation of the Canadian Borrower to reimburse the Canadian
Revolving Credit Lenders for then-maturing Acceptances may be satisfied by the
Canadian Borrower by:

               (i)   paying to the Canadian Administrative Agent, for the
     account of the Canadian Revolving Credit Lenders, an amount in Canadian
     Dollars and in immediately available funds equal to the aggregate
     undiscounted face amount of all Acceptances created for the account of the
     Canadian Borrower hereunder which are then maturing by 12:00 Noon, Toronto
     time, on such maturity date; provided that the Canadian Borrower shall have
     given not less than one Business Day's prior notice to the Canadian
     Administrative Agent (which shall promptly notify each Canadian Revolving
     Credit Lender thereof) of its intent to reimburse the Canadian Revolving
     Credit Lenders in the manner contemplated by this clause (i);

               (ii)  having new Drafts accepted and discounted by the Canadian
     Revolving Credit Lenders in the manner contemplated by Sections 5.7 and 5.8
     in substitution for the then-maturing Acceptances; provided that (A) the
                                                        --------
     Canadian Borrower shall have delivered to the Canadian Administrative Agent
     (which shall promptly provide a copy thereof to each Canadian Revolving
     Credit Lender) a duly completed Request for Acceptances not later than 2:00
     P.M., Toronto time, one Business Day prior to such maturity date, together
     with the documents, instruments, certificates and other papers and
     information contemplated by Section 5.7(a)(ii) and 5.7(a)(iii), (B) if any
     Default or Event of Default has occurred and is then continuing, the
     Request for Acceptances shall be deemed to be a request for a Canadian
     Revolving Credit Loan in an amount equal to the undiscounted face amount of
     the Acceptances requested, (C) each Canadian Revolving Credit Lender shall
     retain the Acceptance Purchase Price for the Acceptance created by it and
     apply such Acceptance Purchase Price to the Acceptance Reimbursement
     Obligations of the Canadian Borrower in respect of the maturing Acceptance
     created by such Canadian Revolving Credit Lender, (D) if the Acceptance
     Purchase Price so retained by such Canadian Revolving Credit Lender is less
     than the undiscounted face amount of the then-maturing Acceptance, the
     Canadian Borrower shall have made arrangements reasonably satisfactory to
     such Canadian Revolving Credit Lender for payment of such deficiency and
     (E) if the Acceptance Purchase Price so retained by the Canadian Revolving
     Credit Lender is greater than the undiscounted face amount of the then-
     maturing Acceptance, the Canadian Revolving Credit Lender shall make such
     excess available to the Canadian Administrative Agent, which in turn shall
     make such excess available to the Canadian Borrower, all in accordance with
     Section 5.8(b); or
<PAGE>

                                                                              58

               (iii) no the extent that the Canadian Borrower has not given to
     the Canadian Administrative Agent a notice contemplated by clause (i) or
     (ii) above, then the Canadian Borrower shall be deemed to have requested a
     borrowing pursuant to Section 5.1 of Canadian Revolving Credit Loans in an
     aggregate principal amount equal to the undiscounted face amount of such
     then-maturing Acceptance. The Borrowing Date with respect to such borrowing
     shall be the maturity date for such Acceptance. Except to the extent that
     any of the events contemplated by paragraph (f) of Section 13 with respect
     to the Canadian Borrower has occurred and is then continuing, each Canadian
     Revolving Credit Lender shall be obligated to make the Canadian Revolving
     Credit Loan contemplated by this Section 5.10(b)(iii) regardless of whether
     the conditions precedent to borrowing set forth in this Agreement are then
     satisfied. The proceeds of any Canadian Revolving Credit Loans made
     pursuant to this Section 5.10(b)(iii) shall be retained by the Canadian
     Revolving Credit Lenders and applied by them to the Acceptance
     Reimbursement Obligations of the Canadian Borrower in respect of the then-
     maturing Acceptance.

          (c)  The unpaid amount of any such Acceptance Reimbursement
Obligations shall be treated as a Canadian Revolving Credit Loan for the
purposes hereof and interest shall accrue on the amount of any such unpaid
Acceptance Reimbursement Obligation from the date such amount becomes due until
paid in full at a fluctuating rate per annum equal to the rate which would then
be payable on Canadian Revolving Credit Loans.  Such interest shall be payable
by the Canadian Borrower on demand by the Canadian Administrative Agent.

          (d)  In no event shall the Canadian Borrower claim from any Canadian
Revolving Credit Lender any grace period with respect to the payment at maturity
of any Acceptances created by such Canadian Revolving Credit Lender pursuant to
this Agreement.

          5.11 Converting Canadian Revolving Credit Loans to Acceptances and
               -------------------------------------------------------------
Acceptances to Canadian Revolving Credit Loans.  (a)  Subject to Section
----------------------------------------------
5.11(b), the Canadian Borrower may at any time and from time to time request
that any then outstanding Canadian Revolving Credit Loan denominated in Canadian
Dollars be converted into an Acceptance by delivering to the Canadian
Administrative Agent (which shall promptly notify the General Administrative
Agent and each Canadian Revolving Credit Lender of its receipt thereof) a
Request for Acceptances, together with a statement that the Acceptances so
requested are to be created pursuant to this Section 5.11(a), such notice to be
given not later than two Business Days prior to the requested conversion date.

          (b)  In the event that the Canadian Administrative Agent receives such
a Request for Acceptances and the accompanying statement described in Section
5.11(a), then the Canadian Borrower shall pay on the requested Borrowing Date to
the Canadian Administrative Agent, for the account of the Canadian Revolving
Credit Lenders, the principal amount of the then outstanding Canadian Revolving
Credit Loans being so converted, and each Canadian Revolving Credit Lender shall
accept and discount the Canadian Borrower's Draft having an aggregate face
amount equal to the principal amount of the Canadian Revolving Credit Loans of
such Canadian Revolving Credit Lender which are then being repaid; it being
understood and agreed that for the
<PAGE>

                                                                              59

purposes of this Section 5.11(b), such payment by the Canadian Borrower of such
outstanding Canadian Revolving Credit Loans may be from the proceeds of such
discounted Drafts, provided that, (i) following the occurrence and during the
                   --------
continuance of a Default or an Event of Default, no Acceptances may be created,
(ii) the Canadian Borrower shall make arrangements reasonably satisfactory to
each Canadian Revolving Credit Lender for payment of any deficiency, including,
without limitation, the difference between the undiscounted face amount of the
Acceptance to be created pursuant to Section 5.11(a) and the Acceptance Purchase
Price and any other amount owing by the Canadian Borrower and (iii) no
Acceptance which is permitted to be created hereunder shall have a maturity that
extends beyond the Canadian Revolving Credit Termination Date.

          (c)  The creation of Acceptances pursuant to this Section 5.11 shall
not be subject to the satisfaction of the conditions precedent to borrowing set
forth in this Agreement.

          (d)  The Canadian Borrower may elect from time to time to convert
outstanding Acceptances to Canadian Revolving Credit Loans denominated in
Canadian Dollars by giving the Canadian Administrative Agent at least one
Business Day's irrevocable notice of such election prior to the maturity of such
Acceptances; provided that any such conversion of  Acceptances may only be made
             --------
on the maturity thereof.

          (e)  On any date on which a conversion or substitution of a maturing
Acceptance shall occur, the Canadian Administrative Agent shall be entitled to
net all amounts payable on such date by the Canadian Administrative Agent to a
Canadian Revolving Credit Lender against all amounts payable on such date by
such Canadian Revolving Credit Lender to the Canadian Administrative Agent.
Similarly, on any such date, the Canadian Borrower hereby authorizes each
Canadian Revolving Credit Lender to net all amounts payable on such date by such
Canadian Revolving Credit Lender to the Canadian Administrative Agent for the
account of the Canadian Borrower, against all amounts payable on such date by
the Canadian Borrower to such Canadian Revolving Credit Lender in accordance
with the Canadian Administrative Agent's calculations.

          5.12 Allocation of Acceptances.  The Canadian Borrower hereby agrees
               -------------------------
that each Request for Acceptances, reimbursement of Acceptances and conversion
of Canadian Revolving Credit Loans to Acceptances shall be made in a manner so
that any such Request for Acceptances, reimbursement or conversion shall apply
ratably to all Canadian Revolving Credit Lenders in accordance with their
respective Canadian Revolving Credit Commitment Percentages. In the event that
the aggregate undiscounted face amount of Acceptances requested by the Canadian
Borrower to be created by all Canadian Revolving Credit Lenders hereunder
pursuant to any Request for Acceptances is an amount which, if divided ratably
among the Canadian Revolving Credit Lenders in accordance with their respective
Canadian Revolving Credit Commitment Percentages, would not result in each
Canadian Revolving Credit Lender accepting a Draft which has an undiscounted
face amount equal to C$100,000 or a whole multiple of C$100,000 in excess
thereof, then, notwithstanding any provision in this Section 5.12 to the
contrary, the Canadian Administrative Agent is authorized by the Canadian
Borrower and the Canadian Revolving Credit Lenders to allocate among the
Canadian Revolving Credit Lenders the Acceptances to be issued in such manner
and amounts as the Canadian Administrative Agent may,
<PAGE>

                                                                              60

in its sole discretion, acting reasonably, consider necessary, rounding up or
down, so as to ensure that no Canadian Revolving Credit Lender is required to
accept a Draft for a fraction of C$100,000 and, in such event, the Canadian
Revolving Credit Lenders' ratable share with respect to such  Acceptances
shall be adjusted accordingly.

          5.13 Special Provisions Relating to Acceptance Notes.  (a)  The
               -----------------------------------------------
Canadian Borrower and each Canadian Revolving Credit Lender hereby acknowledge
and agree that from time to time certain Canadian Revolving Credit Lenders which
are not Canadian chartered banks or which are Schedule II Canadian Revolving
Credit Lenders may not be authorized to or may, as a matter of general corporate
policy, elect not to accept Drafts, and the Canadian Borrower and each Canadian
Revolving Credit Lender agree that any such Canadian Revolving Credit Lender may
purchase Acceptance Notes of the Canadian Borrower in accordance with the
provisions of Section 5.13(b) in lieu of creating Acceptances for its account.

          (b)  In the event that any Canadian Revolving Credit Lender
described in Section 5.13(a) above is unable to, or elects as a matter of
general corporate policy not to, create Acceptances hereunder, such Canadian
Revolving Credit Lender shall not create Acceptances hereunder, but rather, if
the Canadian Borrower requests the creation of such Acceptances, the Canadian
Borrower shall deliver to such Canadian Revolving Credit Lender non-interest
bearing promissory notes (each, an "Acceptance Note") of the Canadian Borrower,
                                    ---------------
substantially in the form of Exhibit J, having the same maturity as the
Acceptances to be created and in an aggregate principal amount equal to the
undiscounted face amount of such Acceptances. Each such Canadian Revolving
Credit Lender hereby agrees to purchase Acceptance Notes from the Canadian
Borrower at a purchase price equal to the Acceptance Purchase Price which would
have been applicable if a Draft in the same aggregate face amount as the
principal amount of its Acceptance Notes and of the same maturity had been
accepted by it (less any stamping fee which would have been paid pursuant to
Section 5.9 if such Lender had created an Acceptance) and such Acceptance Notes
shall be governed by the provisions of this Section 5 as if they were
Acceptances.

                         SECTION 6.  LETTERS OF CREDIT

          6.1  L/C Commitments.  (a)  Subject to the terms and conditions
               ---------------
hereof, each U.S. Issuing Lender, in reliance on the agreements of the other
U.S. Revolving Credit Lenders set forth in Section 6.4(a), agrees to issue
letters of credit ("U.S. Letters of Credit") for the account of the U.S.
                    ----------------------
Borrower on any Business Day during the U.S. Revolving Credit Commitment Period
in such form as may be approved from time to time by such Issuing Lender;
provided, that no Issuing Lender shall have any obligation to issue any U.S.
--------
Letter of Credit if, after giving effect to such issuance, (i) the U.S. L/C
Obligations would exceed the U.S. L/C Commitment or (ii) the aggregate amount of
the Available U.S. Revolving Credit Commitments would be less than zero or (iii)
the Aggregate U.S. Revolving Extensions of Credit would exceed the Borrowing
Base of the U.S. Borrower. Notwithstanding the foregoing, the letter of credit
described on Schedule 6.1 shall, from and after the Closing Date, be deemed to
be a U.S. Letter of Credit issued pursuant to this Section 6.1(a) with the
Lender listed on such schedule being deemed to be the Issuing Lender in
respect of such U.S. Letter of Credit. Each U.S. Letter of

                                                                              61

Credit shall (i) be denominated in U.S. Dollars and (ii) expire no later than
the earlier of (x) the first anniversary of its date of issuance and (y) the
date which is five Business Days prior to the U.S. Revolving Credit Termination
Date, provided that any U.S. Letter of Credit with a one-year term may provide
      --------
for the renewal thereof for additional one-year periods (which shall in no event
extend beyond the date referred to in clause (y) above).

          (b)  Subject to the terms and conditions hereof, each Canadian Issuing
Lender, in reliance on the agreements of the other Canadian Revolving Credit
Lenders set forth in Section 6.4(a), agrees to issue letters of credit
("Canadian Letters of Credit"; together with the U.S. Letters of Credit, the
  --------------------------
"Letters of Credit") for the account of the Canadian Borrower on any Business
 -----------------
Day during the Canadian Revolving Credit Commitment Period in such form as may
be approved from time to time by such Issuing Lender; provided, that no Issuing
                                                      --------
Lender shall have any obligation to issue any Canadian Letter of Credit if,
after giving effect to such issuance, (i) the Canadian L/C Obligations would
exceed the Canadian L/C Commitment, (ii) the aggregate amount of the Aggregate
Available Canadian Revolving Credit Commitments would be less than zero, or
(iii) the Aggregate Canadian Revolving Credit Outstanding would exceed the
Borrowing Base of the Canadian Borrower. Each Canadian Letter of Credit shall
(i) be denominated in U.S. Dollars or Canadian Dollars and (ii) expire no later
than the earlier of (x) the first anniversary of its date of issuance and (y)
the date which is five Business Days prior to the Canadian Revolving Credit
Termination Date, provided that any Canadian Letter of Credit with a one-year
                  --------
term may provide for the renewal thereof for additional one-year periods (which
shall in no event extend beyond the date referred to in clause (y) above).

          (c)  No Issuing Lender shall at any time be obligated to issue any
Letter of Credit hereunder if such issuance would conflict with, or cause such
Issuing Lender or any L/C Participant to exceed any limits imposed by, any
applicable Requirement of Law.

          6.2  Procedure for Issuance of Letters of Credit.  The U.S. Borrower
               -------------------------------------------
or the Canadian Borrower may from time to time request that a U.S. Issuing
Lender or a Canadian Issuing Lender, as the case may be, issue a Letter of
Credit by delivering to such Issuing Lender at its address for notices specified
herein an Application therefor, completed to the satisfaction of such Issuing
Lender, and such other certificates, documents and other papers and information
as such Issuing Lender may request.  Upon receipt of any Application, an Issuing
Lender will process such Application and the certificates, documents and other
papers and information delivered to it in connection therewith in accordance
with its customary procedures and shall promptly issue the Letter of Credit
requested thereby by issuing the original of such Letter of Credit to the
beneficiary thereof or as otherwise may be agreed to by such Issuing Lender and
the relevant Borrower (but in no event shall any Issuing Lender be required to
issue any Letter of Credit earlier than three Business Days after its receipt of
the Application therefor and all such other certificates, documents and other
papers and information relating thereto).  Promptly after issuance by an Issuing
Lender of a Letter of Credit, such Issuing Lender shall furnish a copy of such
Letter of Credit to the relevant Borrower.  Each Issuing Lender shall promptly
furnish to the General Administrative Agent (and, in the case of a Canadian
Letter of Credit, to the Canadian Administrative Agent), notice of the issuance
of each Letter of Credit issued by it (including the amount thereof) and such
Agent shall promptly upon receipt of such notice notify each Lender.

                                                                              62

          6.3  Fees and Other Charges.  (a) Each Borrower will pay a fee on the
               ----------------------
aggregate drawable amount of all outstanding Letters of Credit issued for such
Borrower's account at a per annum rate equal to the Applicable Margin then in
effect with respect to Eurodollar Loans under the U.S. Revolving Credit
Facility, shared ratably among the U.S. Revolving Credit Lenders or the Canadian
Revolving Credit Lenders, as the case may be, in accordance with their
respective U.S. Revolving Credit Percentages or Canadian Revolving Credit
Percentages, as the case may be, and payable quarterly in arrears on each L/C
Fee Payment Date after the issuance date.  In addition, each Borrower shall pay
to the relevant Issuing Lender for its own account a fronting fee on the
aggregate drawable amount of each outstanding Letter of Credit issued by such
Issuing Lender for the account of such Borrower of 1/4 of 1% per annum, payable
quarterly in arrears on each L/C Fee Payment Date after the issuance date of
such Letter of Credit.

          (b)  In addition to the foregoing fees, each Borrower shall pay or
reimburse each Issuing Lender for such normal and customary costs and expenses
as are incurred or charged by the Issuing Lender in issuing, negotiating,
effecting payment under, amending or otherwise administering any Letter of
Credit issued for such Borrower's account.

          (c)  Fees payable in respect of any Letter of Credit shall be payable
in the currency in which such Letter of Credit is denominated.

          6.4  L/C Participations.  (a)  Each Issuing Lender irrevocably agrees
               ------------------
to grant and hereby grants to each L/C Participant, and, to induce each Issuing
Lender to issue Letters of Credit hereunder, each L/C Participant irrevocably
agrees to accept and purchase and hereby accepts and purchases from each Issuing
Lender, on the terms and conditions hereinafter stated, for such L/C
Participant's own account and risk an undivided interest equal to (i) in the
case of each U.S. L/C Participant, such U.S. L/C Participant's U.S. Revolving
Credit Percentage in each Issuing Lender's obligations and rights under each
U.S. Letter of Credit issued by such Issuing Lender hereunder and the amount of
each draft paid by such Issuing Lender thereunder and (ii) in the case of each
Canadian L/C Participant, such Canadian L/C Participant's Canadian Revolving
Credit Percentage in each Issuing Lender's obligations and rights under each
Canadian Letter of Credit issued by such Issuing Lender hereunder and the amount
of each draft paid by such Issuing Lender thereunder.  Each L/C Participant
unconditionally and irrevocably agrees with each Issuing Lender that, if a draft
is paid under any Letter of Credit in which such L/C Participant has a
participating interest for which the relevant Issuing Lender is not reimbursed
in full by the relevant Borrower in accordance with the terms of this Agreement,
such L/C Participant shall pay to such Issuing Lender upon demand at such
Issuing Lender's address for notices specified herein an amount equal to such
L/C Participant's U.S. Revolving Credit Percentage (in the case of U.S. Letters
of Credit) or Canadian Revolving Credit Percentage (in the case of Canadian
Letters of Credit) of the amount of such draft, or any part thereof, that is not
so reimbursed.

          (b)  If any amount required to be paid by any L/C Participant to an
Issuing Lender pursuant to Section 6.4(a) in respect of any unreimbursed portion
of any payment made by such Issuing Lender under any Letter of Credit is paid to
such Issuing Lender within three Business Days after the date such payment is
due, such L/C Participant shall pay to such Issuing Lender on

funding the overdue amount (in the case of amounts owing in Canadian Dollars)
during the period from and including the date such payment is required to the
date on which such payment is immediately available to such Issuing Lender,
times (iii) a fraction the numerator of which is the number of days that elapse
during such period and the denominator of which is 360.  If any such amount
required to be paid by any L/C Participant pursuant to Section 6.4(a) is not

from the relevant Borrower or otherwise, including proceeds of collateral
applied thereto by such Issuing Lender), or any payment of interest on account
thereof, such Issuing Lender will distribute to such L/C Participant its pro
                                                                         ---
rata share thereof; provided, however, that in the event that any such payment
----                --------  -------
received by such Issuing Lender shall be required to be returned by such Issuing
Lender, such L/C Participant shall return to such Issuing Lender the portion
thereof previously distributed by such Issuing Lender to it.

any Letter of Credit issue for the account of such Borrower and paid by such
Issuing Lender for the amount of (a) such draft so paid and (b) any taxes, fees,
charges or other costs or expenses incurred by such Issuing Lender in connection
with such payment (the amounts described in the foregoing clauses (a) and (b) in
respect of any drawing, collectively, the "Payment Amount").  Each such payment
                                           --------------
shall be made to such Issuing Lender at its address for notices specified herein
in the currency in which such amount is owing and in immediately available
funds. Interest shall be payable on each Payment Amount from the date of the
applicable drawing until payment in full at the rate set forth in (i) until the
second Business Day following the date of the applicable drawing, Section 7.1(b)
(in the case of amounts outstanding in U.S. Dollars) in Section 7.1(c) (in the
case of amounts outstanding in Canadian Dollars) and (ii) thereafter, Section
7.1(e). Each drawing under any Letter of Credit shall (unless an event of the

continuing with respect to the Borrower, in which case the procedures specified
in Section 6.4 for funding by L/C Participants shall apply) constitute a request

drawing.  The Borrowing Date with respect to such borrowing shall be the first
date on which a borrowing of U.S. Revolving Credit Loans, Canadian Revolving
Credit Loans or applicable, Swing Line Loans, as the case may be, could be made,
pursuant to Section 2.5, 5.2 or 2.7, as the case may be, if the relevant
Administrative Agent had received a notice of such borrowing at the time such
Administrative Agent receives notice from the relevant Issuing Lender of such
drawing under such Letter of Credit.

          6.6  Obligations Absolute.  Each Borrower's obligations under this

Section 6 shall be absolute and unconditional under any and all circumstances
and irrespective of any setoff, counterclaim or defense to payment that such
Borrower may have or have had against any Issuing Lender, any beneficiary of a
Letter of Credit or any other Person.  Each Borrower also agrees with each
Issuing Lender that such Issuing Lender shall not be responsible for, and such
Borrower's Reimbursement Obligations under Section 6.5 shall not be affected by,
among other things, the validity or genuineness of documents or of any
endorsements thereon, even though such documents shall in fact prove to be
invalid, fraudulent or forged, or any dispute between or among such Borrower and
any beneficiary of any Letter of Credit or any other party to which such Letter
of Credit may be transferred or any claims whatsoever of such Borrower against
any beneficiary of such Letter of Credit or any such transferee.  No Issuing
Lender shall be liable for any error, omission, interruption or delay in
transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit, except for errors or
omissions resulting from the gross negligence or willful misconduct of such
Issuing Lender.  Each Borrower agrees that any action taken or omitted by an
Issuing Lender under or in connection with any Letter of Credit issued by it or
the related drafts or documents, if done in the absence of gross negligence or
willful misconduct and in accordance with the standards or care specified in the
Uniform Commercial Code of the State of New York, shall be binding on such
Borrower and shall not result in any liability of such Issuing Lender to such
Borrower.

          6.7  Letter of Credit Payments.  If any draft shall be presented for
               -------------------------
payment under any Letter of Credit, the relevant Issuing Lender shall promptly
notify the relevant Borrower of the date and amount thereof.  The responsibility
of the relevant Issuing Lender to the relevant Borrower in connection with any
draft presented for payment under any Letter of Credit shall, in addition to any
payment obligation expressly provided for in such Letter of Credit issued by
such Issuing Lender, be limited to determining that the documents (including
each draft) delivered under such Letter of Credit in connection with such
presentment appear on their face to be in conformity with such Letter of Credit.

          6.8  Applications.  To the extent that any provision of any
               ------------
Application related to any Letter of Credit is inconsistent with the provisions
of this Section 6, the provisions of this Section 6 shall apply.

made first to U.S. Base Rate Loans and second to Eurodollar Loans (in a manner,
to the extent practicable and permitted hereunder, which minimizes amounts
payable under Section 7.12 as a result of such prepayment). The application of
any such prepayment to Aggregate Canadian Term Loan Outstandings shall be made
first to Canadian Base Rate Loans and second to Eurodollar Loans (in a manner,
to the extent practicable and permitted hereunder, which minimizes amounts
payable under Section 7.12 as a result of such prepayment).  Each such
prepayment of Loans (except in the case of Swing Line Loans, U.S. Revolving
Credit Loans that are U.S. Base Rate Loans and Canadian Revolving Credit Loans
that are Canadian Prime Rate Loans or Canadian Base Rate Loans) shall be
accompanied by accrued interest to the date of such prepayment on the amount
prepaid.

          (f) Subject to Section 7.9, amounts to be applied in connection with
prepayments and reductions made pursuant to Section 7.4(a), the first sentence
of Section 7.5(c) or the first sentence of  Section 7.5(d) shall be applied,
first, to the prepayment of the Tranche A Term Loans and Tranche B Term Loans,
-----
ratably in accordance with the respective outstanding amounts of the Facilities,
and, second, after prepayment in full of the amounts described in the foregoing
     ------
clause first, 50% of any remaining portion of amounts to be applied pursuant to
       -----
Section 7.4(a), the first sentence of Section 7.5(c) or the first sentence of
Section 7.5(d) shall be applied to reduce permanently the U.S. Revolving Credit
Commitments.  Any such reduction of the U.S. Revolving Credit Commitments shall
be accompanied by prepayment of the U.S. Revolving Credit Loans and/or Swing
Line Loans to the extent, if any, that the Aggregate U.S. Revolving Extensions
of Credit exceed the amount of the aggregate U.S. Revolving Credit Commitments
as so reduced, provided that if the aggregate principal amount of U.S. Revolving
               --------
Credit Loans and/or Swing Line Loans then outstanding is less than the amount of
such excess (because L/C Obligations constitute a portion thereof), the U.S.
Borrower shall not be required to reduce any outstanding U.S. Letters of Credit.
The application of any such prepayment of U.S. Term Loans shall be made first to
U.S. Base Rate Loans and second to Eurodollar Loans (in a manner, to the extent
practicable and permitted hereunder, which minimizes amounts payable under
Section 7.12 as a result of such prepayment).  Each such prepayment of the Loans
(except in the case of Swing Line Loans and U.S. Revolving Credit Loans that are
U.S. Base Rate Loans) shall be accompanied by accrued interest to the date of
such prepayment on the amount prepaid.

          (g)  Subject to Section 7.9, amounts to be applied in connection with
prepayments and reductions made pursuant to Section 7.4(b), the second sentence
of Section 7.5(c) or the
<PAGE>

                                                                              71

second sentence of Section 7.5(d) shall be applied, first, to the reduction of
                                                    -----
the Aggregate Canadian Term Loan Outstandings and the simultaneous and automatic
reduction in an equal amount of the Canadian Facility Maximum Amount and,
second, after prepayment in full of the amounts described in the foregoing
------
clause first, 50% of any remaining portion of amounts to be applied pursuant to
       -----
Section 7.4(b), the second sentence of Section 7.5(c) or the second sentence of
Section 7.5(d) shall be applied to permanently reduce the Canadian Revolving
Credit Commitments. The application of any such prepayment to Aggregate Canadian
Term Loan Outstandings shall be made first to Canadian Base Rate Loans and
second to Eurodollar Loans (in a manner, to the extent practicable and permitted
hereunder, which minimizes amounts payable under Section 7.12 as a result of
such prepayment).  Each such prepayment of the Canadian Term Loans shall be
accompanied by accrued interest to the date of such prepayment on the amount
prepaid.

          (h)  The amount of each prepayment of the Loans made pursuant to
Section 7.4 or Section 7.5 shall be applied to reduce the then remaining
installments of the Loans under the relevant Facility pro rata based upon the
                                                      --- ----
then remaining outstanding principal amount of such installments; provided, that
                                                                  --------
the relevant Borrower may elect for such prepayments to be first applied to
installments payable under such Loans during the twelve months following the
date of such prepayment.

          (i)  Notwithstanding anything in Section 7.4(a), Section 7.5(e) or
Section 7.5(f) to the contrary and provided that there are Tranche A Term Loans
then outstanding, with respect to the amount of any optional prepayment
described in Section 7.4(a) or mandatory prepayment described in Section 7.5
that is allocated to the Tranche B Term Loans (such amounts, the "Tranche B
                                                                  ---------
Prepayment Amount"), the U.S. Borrower will, in lieu of applying such amount to
-----------------
the prepayment of Tranche B Term Loans, as provided in Section 7.4(a) or Section
7.5(e) or (f), as the case may be, on the date specified in Section 7.4(a) or
Section 7.5, as the case may be, for such prepayment, give the General
Administrative Agent telephonic notice (promptly confirmed in writing)
requesting that the General Administrative Agent prepare and provide to each
Tranche B Lender a notice (each, a "Prepayment Option Notice") as described
                                    ------------------------
below.  As promptly as practicable after receiving such notice from the U.S.
Borrower, the General Administrative Agent will send to each Tranche B Lender a
notice (a "Prepayment Option Notice"), which shall be in the form of Exhibit K,
           ------------------------
and shall include an offer by the U.S. Borrower to prepay on the date (each a
"Proposed Prepayment Date") that is 15 days after the date of the Prepayment
 ------------------------
Option Notice, the Tranche B Term Loans of such Lender by an amount equal to the
portion of the Tranche B Prepayment Amount indicated in such Lender's Prepayment
Option Notice as being applicable to such Lender's Tranche B Term Loans (which
shall be such Lender's pro rata share of the Tranche B Prepayment Amount).  On
the Proposed Prepayment Date, (A) the U.S. Borrower shall pay to the General
Administrative Agent the aggregate amount necessary to prepay that portion of
the outstanding Tranche B Term Loans in respect of which Tranche B Lenders have
accepted prepayment as described above (such Lenders, the "Accepting Lenders"),
                                                           -----------------
and such amount shall be applied to reduce the Tranche B Prepayment Amount with
respect to each Accepting Lender and (B) the U.S. Borrower may retain 50% of the
Tranche B Prepayment Amount not accepted for prepayment and shall pay to the
General Administrative Agent an amount equal to 50% of the portion of the
Tranche B Prepayment Amount not accepted for prepayment, and such amount

                                                                              72

shall be applied (i) in the case of optional prepayments pursuant to Section
7.4, to prepay the Tranche A Term Loans and (ii) in the case of mandatory
prepayments, to the other Facilities required to be prepaid pursuant to Section
7.5(e) or Section 7.5(f), as the case may be, ratably in accordance with the
outstanding amounts thereof.

          7.6  Certain Fees.  (a)  The U.S. Borrower shall pay (without
               ------------
duplication of any other fee payable under this Section 7.6) to the Arranger and
the Syndication Agent, for their respective accounts, all fees separately agreed
to by the U.S. Borrower and the Arranger and the Syndication Agent, as the case
may be.

          (b)  The Canadian Borrower shall (without duplication of any other fee
payable under this Section 7.6) pay to the Canadian Administrative Agent all
fees separately agreed to by the Canadian Borrower and the Canadian
Administrative Agent.

          (c)  The U.S. Borrower shall (without duplication of any other fee
payable under this Section 7.6) pay to the General Administrative Agent all fees
separately agreed to by the U.S. Borrower and the General Administrative Agent.

          7.7  Computation of Interest and Fees.  (a)  Interest based on the
               --------------------------------
Eurodollar Rate the Canadian Prime Rate, the Canadian Base Rate, or the U.S.
Base Rate when it is based upon the Federal Funds Effective Rate shall be
calculated on the basis of a 360-day year for the actual days elapsed; and
commitment fees, letters of credit fees and interest (other than interest based
the Canadian Prime Rate, the Canadian Base Rate, upon the Eurodollar Rate or the
U.S. Base Rate when it is based upon the Federal Funds Effective Rate) shall be
calculated on the basis of a 365-(or 366-, as the case may be) day year for the
actual days elapsed.  The General Administrative Agent shall as soon as
practicable notify the relevant Borrower and the relevant Lenders of each
determination of a Eurodollar Rate. Any change in the interest rate on a Loan
resulting from a change in the U.S. Base Rate, the Canadian Base Rate or the
Canadian Prime Rate shall become effective as of the opening of business on the
day on which such change becomes effective.  The General Administrative Agent
shall as soon as practicable notify the U.S. Borrower and the Lenders of the
effective date and the amount of each such change in the U.S. Base Rate, and the
Canadian Administrative Agent shall as soon as practicable notify the U.S.
Borrower and Canadian Borrower and the Canadian Revolving Credit Lenders of each
such change in the Canadian Prime Rate and the Canadian Base Rate; provided that
                                                                   --------
a failure by the General Administrative Agent or the Canadian Administrative
Agent to notify the U.S. Borrower or the Canadian Borrower of such respective
rate changes does not affect the obligation of the U.S. Borrower or the Canadian
Borrower to pay interest at the applicable rate as changed.  For purposes of the
Interest Act (Canada), whenever any interest or fee under this Agreement is
calculated based on a period which is less than a year (the "Lesser Period"),
                                                             -------------
the interest rate or fee determined pursuant to such calculation, when expressed
as an annual rate, is equivalent to (i) the applicable rate based on such Lesser
Period, (ii) multiplied by the actual number of days in the calendar year in
which the period for which such interest or fee is payable ends, and (iii)
divided by the number of days in such Lesser Period.  The rates of interest
specified in this Agreement are nominal rates and all interest payments and
computations are to be made without allowance or deduction for deemed
reinvestment of interest.

          (b)  Each determination of an interest rate by the General
Administrative Agent or the Canadian Administrative Agent, as the case may be,
pursuant to any provision of this Agreement shall be conclusive and binding on
the Borrowers and the Lenders in the absence of manifest error.  Each
Administrative Agent shall, at the request of a Borrower, deliver to such
Borrower a statement showing in reasonable detail the calculations used by such
Administrative Agent in determining any interest rate pursuant to Section
7.1(a).

          (c)  If any Canadian Reference Lender shall for any reason no longer
have a Canadian Revolving Credit Commitment or any Canadian Revolving Credit
Loans, such Canadian Reference Lender shall thereupon cease to be a Canadian
Reference Lender, and if, as a result, there shall only be one Schedule I
Canadian Reference Lender or Schedule II Canadian Reference Lender (as the case
may be) remaining, the Canadian Administrative Agent, with the consent of the
Canadian Borrower (after consultation with the Schedule I Canadian Lenders or
the Schedule II Canadian Lenders, as applicable) shall, by notice to the
Canadian Borrower and the Canadian Lenders, designate another Schedule I
Canadian Lender or Schedule II Canadian Lender, as applicable, as a Schedule I
Canadian Reference Lender or a Schedule II Canadian Reference Lender, as
applicable, so that there shall at all times be at least two Schedule I Canadian
Reference Lenders and two Schedule II Canadian Reference Lenders.

          (d)  Each Canadian Reference Lender shall use its best efforts to
furnish quotations of rates to the Canadian Administrative Agent as contemplated
hereby.  If any of the Canadian Reference Lenders shall be unable or shall
otherwise fail to supply such rates to the applicable Administrative Agent upon
its request, the rate of interest shall, subject to the provisions of Section
7.8, be determined on the basis of the quotations of the remaining Canadian
Reference Lenders or Reference Lender.

          7.8  Inability to Determine Interest Rate.  If prior to the first day
               ------------------------------------
of any Interest Period:

          (a)  the General Administrative Agent shall have determined (which
     determination shall be conclusive and binding upon the Borrowers absent
     manifest error) that, by reason of circumstances affecting the relevant
     market, adequate and reasonable means do not exist for ascertaining the
     Eurodollar Rate for such Interest Period, or

          (b)  the General Administrative Agent has received notice from the
     Majority Facility Lenders that the Eurodollar Rate determined or to be
     determined for such Interest Period will not adequately and fairly reflect
     the cost to such Lenders of making or maintaining their Eurodollar Loans
     during such Interest Period,

the General Administrative Agent shall give telecopy or telephonic notice
thereof to the Borrower and the relevant Lenders as soon as practicable
thereafter.  If such notice is given (x) any Eurodollar Loans under the relevant
Facility requested to be made on the first day of such Interest Period shall be
made as Base Rate Loans, (y) any Loans under the relevant Facility that were to
have been converted on the first day of such Interest Period to Eurodollar Loans
shall be continued as Base Rate Loans and (z) any outstanding Eurodollar Loans
under the relevant
<PAGE>

                                                                              74

Facility shall be converted, on the first day of such Interest Period, to Base
Rate Loans.  Until such time as the Eurodollar Rate can be determined by the
General Administrative Agent in the manner specified in the definitions of such
terms in subsection 1.1, no further Eurodollar Loans under the affected Facility
shall be continued as such at the end of the then current Interest Periods or
shall be made, nor shall the relevant Borrower have the right to convert
outstanding Loans under such Facility into Eurodollar Loans.  The Administrative
Agent shall withdraw (i) any such notice pursuant to clause (a) above if the
Administrative Agent determines that the relevant circumstances have ceased to
exist and (ii) any such notice pursuant to clause (b) above upon receipt of
notice from the Majority Facility Lenders in respect of the relevant Facility
that the relevant circumstances described in such clause (b) have ceased to
exist.

          7.9   Pro Rata Treatment and Payments.  (a) (i)  Each borrowing from
                -------------------------------
the Lenders under any Facility shall be made pro rata according to the
                                             --- ----
respective Commitment Percentages of the Lenders in respect of such Facility in
effect on the date of such borrowing.  Each payment on account of any commitment
fee or letter of credit fee relating to any Facility shall be allocated by the
relevant Administrative Agent among the Lenders in accordance with the
respective Commitment Percentages of the Lenders in respect of such Facility.
Any reduction of the Commitments under any Facility shall be allocated among the
Lenders pro rata according to the Commitment Percentages of the Lenders in
        --- ----
respect of such Facility.  Each payment (other than any optional prepayment) by
a Borrower on account of principal of the Loans shall be allocated by the
relevant Administrative Agent pro rata according to the respective principal
                              --- ----
amounts thereof then due and owing to each Lender.  Each payment by a Borrower
on account of interest on the Loans shall be allocated by the relevant
Administrative Agent pro rata according to the respective amounts of interest
                     --- ----
then due and owing to each Lender.  Each optional prepayment on account of
principal of or interest on the Loans under any Facility shall be allocated by
the relevant Administrative Agent pro rata according to the respective
                                  --- ----
outstanding principal amounts of Loans outstanding under such Facility.

          (ii)  All payments (including prepayments) to be made by the U.S.
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 1:00 P.M., New York City time, on the due date thereof to the General
Administrative Agent, for the account of the U.S. Lenders, at the U.S. Payment
Office, in U.S. Dollars and in immediately available funds.  The General
Administrative Agent shall distribute such payments to the U.S. Lenders entitled
to receive the same promptly upon receipt in like funds as received.

          (iii) 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 1:00 P.M., Toronto time, on the due date thereof to the Canadian
Administrative Agent, for the account of the Canadian Lenders, at the Canadian
Payment Office, in the currency in which the relevant amount is outstanding and
in immediately available funds.  The Canadian Administrative Agent shall
distribute such payments to the Canadian Lenders entitled to receive the same
promptly upon receipt in like funds as received.
<PAGE>

                                                                              75

          (iv) If any payment hereunder (other than payments on the Eurodollar
Loans and the Acceptances) becomes due and payable on a day other than a
Business Day, the maturity of such payment shall be extended to the next
succeeding Business Day, and, with respect to payments of principal, interest
thereon shall be payable at the then applicable rate during such extension.  If
any payment on a Eurodollar Loan becomes due and payable on a day other than a
Business Day, the maturity of such payment shall be extended to the next
succeeding Business Day (and, with respect to payments of principal, interest
thereon shall be payable at the then applicable rate during such extension)
unless the result of such extension would be to extend such payment into another
calendar month, in which event such payment shall be made on the immediately
preceding Business Day.  Acceptances may only mature on a Business Day.

          (b)  Unless the applicable Administrative Agent shall have been
notified in writing by any Lender prior to a Borrowing Date that such Lender
will not make the amount that would constitute its share of such borrowing
available to such Administrative Agent, such Administrative Agent may assume
that such Lender is making such amount available to such Administrative Agent,
and such Administrative Agent may, in reliance upon such assumption, make
available to the applicable Borrower a corresponding amount.  If such amount is
not made available to such Administrative Agent by the required time on the
Borrowing Date therefor, such Lender shall pay to such Administrative Agent, on
demand, such amount with interest thereon at a rate per annum equal to (i) the
daily average Federal Funds Effective Rate (in the case of a borrowing of Loans
in U.S. Dollars), and (ii) the Canadian Administrative Agent's reasonable
estimate of its average daily cost of funds (in the case of a borrowing of Loans
or Acceptances in Canadian Dollars), in each case for the period until such
Lender makes such amount immediately available to such Administrative Agent.  A
certificate of such Administrative Agent submitted to any Lender with respect to
any amounts owing under this subsection shall be conclusive in the absence of
manifest error.  If such Lender's share of such borrowing is not made available
to such Administrative Agent by such Lender within three Business Days of such
Borrowing Date, the applicable Borrower shall repay such Lender's share of such
borrowing (together with interest thereon from the date such amount was made
available to such Borrower (i) at the rate per annum applicable to U.S. Base
Rate Loans under the relevant Facility (in the case of amounts made available to
the U.S. Borrower and amounts made available in U.S. Dollars to the Canadian
Borrower) and (ii) at the rate per annum applicable to Canadian Prime Rate Loans
under the relevant Facility (in the case of amounts made available in Canadian
Dollars to the Canadian Borrower) to such Administrative Agent not later than
three Business Days after receipt of written notice from such Administrative
Agent specifying such Lender's share of such borrowing that was not made
available to such Administrative Agent.  Nothing contained in this Section
7.9(b) shall prejudice any claims otherwise available to any Borrower against
any Lender as a result of such Lender's failure to make its share of any
borrowing available to an Administrative Agent for the account of a Borrower.

          7.10 Illegality.  (a)  Notwithstanding any other provision herein, if
               ----------
the adoption of or any change in any Requirement of Law or in the interpretation
or application thereof shall make it unlawful for any Lender to make or maintain
Eurodollar Loans as contemplated by this Agreement, (i) the commitment of such
Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and
convert U.S. Base Rate Loans or Canadian Base Rate Loans to
<PAGE>

                                                                              76

Eurodollar Loans shall forthwith be cancelled until such time as it shall no
longer be unlawful for such Lender to make or maintain the affected Loans and,
(ii) such Lender's Loans then outstanding as Eurodollar Loans, if any, shall be
converted automatically to U.S. Base Rate Loans or Canadian Base Rate Loans, as
the case may be, on the respective last days of the then current Interest
Periods with respect to such Eurodollar Loans or within such earlier period as
may be required by law.  If any such conversion of a Eurodollar Loan occurs on a
day which is not the last day of the then current Interest Period with respect
thereto, the relevant Borrower shall not be obligated to pay to such Lender such
amounts, if any, as may be required pursuant to Section 7.12.

          (b)  Notwithstanding any other provision herein, if the adoption of or
any change in any Requirement of Law or in the interpretation or application
thereof shall make it unlawful for any Canadian Lender to create or maintain
Acceptances as contemplated by this Agreement, (a) the commitment of such
Canadian Lender hereunder to accept Drafts, purchase Acceptances, continue
Acceptances as such and convert Canadian Revolving Credit Loans or Canadian
Dollar Term Loans to Acceptances shall forthwith be cancelled until such time as
it shall no longer be unlawful for such Canadian Lender to create or maintain
Acceptances and (b) such Canadian Lender's then outstanding Acceptances, if any,
shall be converted automatically to Canadian Prime Rate Loans on the respective
maturities thereof or within such earlier period as may be permitted and
required by law.

          (c)  Notwithstanding any other provision herein, if the adoption of or
any change in any Requirement of Law or in the interpretation or application
thereof shall make it unlawful for any Canadian Lender to make or maintain
Canadian Base Rate Loans, (i) the commitment of such Canadian Lender hereunder
to make Canadian Base Rate Loans shall forthwith be cancelled until such time as
it shall no longer be unlawful for such Canadian Lender to make or maintain
Canadian Base Rate Loans and (ii) such Canadian Lender's then outstanding
Canadian Base Rate Loans, if any, shall be converted automatically to Canadian
Dollars at the Exchange Rate and Canadian Prime Rate Loans on the respective
maturities thereof or within such earlier period as may be permitted and
required by law.

          (d) If, by reason of circumstances affecting the money markets
generally, there is no market for Acceptances (i) the right of the Canadian
Borrower to request an Acceptance shall be suspended until the circumstances
causing a suspension no longer exist, and (ii) any Request for an Acceptance
which is outstanding shall be canceled and the requested Acceptance shall not be
available.  The Canadian Administrative Agent shall promptly notify the Canadian
Borrower of the suspension of the Canadian Borrower's right to request an
Acceptance and of the termination of any suspension.

          7.11 Requirements of Law.  (a)  If the adoption of, or any change in,
               -------------------
any Requirement of Law or in the interpretation thereof, or compliance by any
Lender with any request or directive (whether or not having the force of law)
from any central bank or other Governmental Authority:
<PAGE>

                                                                              77

               (i)   shall subject any Lender to any tax of any kind whatsoever
     with respect to this Agreement, any Note, any Acceptance created by it, any
     Letter of Credit issued or participated in by it or any Loans made by it,
     or change the basis of taxation of payments to such Lender of principal,
     fees, interest or any other amount payable hereunder (except for taxes
     covered by Section 7.13 and changes in the rate of tax on the overall net
     income or capital of such Lender);

               (ii)  shall impose, modify or hold applicable any reserve,
     special deposit, compulsory loan or similar requirement against assets held
     by, or deposits or other liabilities in or for the account of, advances or
     loans by, or other credit extended by, or any other acquisition of funds
     by, any office of such Lender which are not otherwise included in the
     determination of the Eurodollar Rate, including, without limitation, the
     imposition of any reserves with respect to Eurocurrency Liabilities under
     Regulation D of the Board; or

               (iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by any amount which such Lender deems to be material, of making, renewing or
maintaining advances or extensions of credit or to reduce any amount receivable
hereunder, in each case in respect of its Loans, its Acceptances or its
Participating Interests, then, in any such case, the applicable Borrower shall,
to the extent permitted by law, promptly pay such Lender, upon receipt of its
demand setting forth in reasonable detail, any additional amounts necessary to
compensate such Lender for such additional cost or reduced amount receivable. If
any Lender becomes entitled to claim any additional amounts pursuant to this
Section, it shall promptly notify the Borrower in reasonable detail (with a copy
to the Administrative Agent) of the event by reason of which it has become so
entitled. This covenant shall survive the termination of this Agreement and
payment of all amounts outstanding hereunder.

          (b)  In the event that any Lender shall have determined that the
adoption of or any change in any Requirement of Law regarding capital adequacy
(or in the interpretation or application thereof) or compliance by such Lender
or any corporation controlling such Lender with any request or directive
regarding capital adequacy (whether or not having the force of law) from any
central bank or Governmental Authority, does or shall have the effect of
reducing the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder to a level below that which such 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 Lender to
be material, then from time to time, after submission by such Lender to the U.S.
Borrower (with a copy to the General Administrative Agent) of a written request
therefor, setting forth in reasonable detail the basis therefor the U.S.
Borrower shall promptly pay to such Lender such additional amount or amounts as
will compensate such Lender for such reduction.

          (c)  If any Lender becomes entitled to claim any additional amounts
pursuant to this Section 7.11 or Section 7.13, it shall promptly notify the
relevant Borrower (with a copy to
<PAGE>

                                                                              78

the Administrative Agent) of the event by reason of which it has become so
entitled, provided that no Lender shall be entitled to claim any such additional
amount with respect to the period which is more than 180 days prior to the
delivery of such notice.

          7.12 Indemnity.  Each Borrower agrees to indemnify each Lender and
               ---------
each Agent and to hold each Lender and each Agent harmless from any loss or
expense (other than any loss of Applicable Margin) which such Lender or such
Agent, as the case may be, may sustain or incur as a consequence of (a) default
by such Borrower in payment when due of the principal amount of or interest on
any Loans of such Lender, (b) default by such Borrower in making a borrowing or
conversion after the Borrower has given a notice of borrowing or a notice of
conversion in accordance with this Agreement, (c) default by such Borrower in
making any prepayment after such Borrower has given a notice in accordance with
this Agreement, (d) the making of a prepayment of a Eurodollar Loan on a day
which is not the last day of an Interest Period with respect thereto, including,
without limitation, any such loss or expense arising from the reemployment of
funds obtained by it or from fees payable to terminate the deposits from which
such funds were obtained, (e) the prepayment of an Acceptance or an Acceptance
Note on a day which is not the maturity date thereof, (f) the failure of the
Canadian Borrower to make any payment, repayment or prepayment on the date
required hereunder or specified by it in any notice hereunder which results in
any cost or expense accrued by reason of the liquidation or re-employment in
whole or in part of deposits or other funds required by any Lender to fund any
Acceptance or (g) the Canadian Borrower's failure to provide for the payment to
the Canadian Administrative Agent or any Lender of the full face amount of each
Acceptance on its maturity date, including, without limitation, in each case,
any such loss or expense arising from the reemployment of funds obtained by it
to maintain its Eurodollar Loans hereunder or from fees payable to terminate the
deposits from which such funds were obtained.  A certificate as to any such loss
or expense submitted by such Lender shall be presumptively correct, absent
manifest error.  This covenant shall survive termination of this Agreement and
payment of all amounts outstanding hereunder.

          7.13 Taxes.  (a) Except as otherwise provided herein, all payments
               -----
made by either 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 any Agent or any Lender
as a result of a present or former connection between such 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 such Agent's or such Lender's 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 any Other Taxes are required to be withheld from any amounts
--------------
payable to any Agent or any Lender hereunder, the amounts so payable to such
Agent or such Lender shall be increased to the extent necessary to yield to such
Agent or such Lender (after payment of all taxes) interest or any such other
amounts payable hereunder at the rates or in the amounts specified in this
Agreement;
<PAGE>

                                                                              79

provided, however, that the Borrowers 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 (d) or (e) of this Section or (ii) that are United States withholding
taxes imposed on amounts payable to such Lender at the time such Lender becomes
a 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
the Borrowers with respect to such Non-Excluded Taxes pursuant to Section
7.13(a).

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

          (c)  Whenever any Non-Excluded Taxes or Other Taxes are payable by any
Borrower, as promptly as possible thereafter such Borrower shall send to the
relevant Administrative Agent for the account of the relevant Agent or Lender,
as the case may be, a certified copy of an original official receipt received by
such Borrower showing payment thereof. If any Borrower fails to pay any Non-
Excluded Taxes or Other Taxes when due to the appropriate taxing authority or
fails to remit to the relevant Administrative Agent the required receipts or
other required documentary evidence, such Borrower shall indemnify the Agents
and the Lenders for any incremental taxes, interest or penalties that may become
payable by any Agent or any Lender as a result of any such failure.  The
agreements in this Section 7.13 shall survive the termination of this Agreement
and the payment of the Loans and all other amounts payable hereunder.

          (d)  Each Lender or Transferee (other than a Canadian Lender) that is
not a U.S. person as defined in section 7701(a)(30) of the Code (a "Non-U.S.
                                                                    --------
Lender") shall deliver to the U.S. Borrower and the General Administrative Agent
------
(or, in the case of a Participant, to the Lender from which the related
participation shall have been purchased) two copies of either U.S. Internal
Revenue Service Form 1001 or Form 4224, 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 L and a Form W-8, or any subsequent
versions thereof or successors thereto properly completed and duly executed by
such Non-U.S. Lender claiming complete exemption from, or a reduced rate of,
U.S. federal withholding tax on all payments by the U.S. Borrower under this
Agreement and the other Loan Documents together with any other certificate or
statement of exemption required under the Code or Regulations issued thereunder.
Such forms shall be delivered by each Non-U.S. Lender on or before the date it
becomes a party to this Agreement (or, in the case of any Participant, on or
before the date such Participant purchases the related participation).  In
addition, each Non-U.S. Lender shall deliver such forms promptly upon the
obsolescence or invalidity of any form previously delivered by such Non-U.S.
Lender.  Each such Non-U.S. Lender shall promptly notify the U.S. Borrower at
any time it determines that it is no longer in a position to provide any
previously delivered certificate to the U.S. Borrower (or any other form of
certification adopted by the U.S. taxing authorities for such purpose).
Notwithstanding any other provision of this paragraph, a Non-U.S. Lender shall
not be required to deliver any form pursuant to this paragraph that such Non-
U.S. Lender is not legally able to deliver.

          (e)  Each Canadian Lender that is entitled to an exemption from or
reduction of Canadian withholding tax with respect to payments under this
Agreement shall deliver to the Canadian Borrower (with a copy to the General
Administrative Agent), at the time or times prescribed by applicable law or
reasonably requested by the Canadian Borrower, such properly completed and
executed documentation prescribed by applicable law as will permit such payments
to be made without withholding or at a reduced rate, provided that such Canadian
                                                     --------
Lender is legally entitled to complete, execute and deliver such documentation
and in such Canadian Lender's reasonable judgment such completion, execution or
submission would not materially prejudice the legal position of such Canadian
Lender.

          (f)  If  an Administrative Agent or any Lender receives a refund or
otherwise would have received a refund but for the offset of the amount of such
refund against the Lender's Non-Excluded Taxes ("Tax Refund"), which in the good
                                                 ----------
faith judgment of such Lender is allocable to Non-Excluded Taxes paid by the
Borrower, it shall promptly pay such Tax Refund to the Borrower, net of all out-
of-pocket expenses of such Lender incurred in obtaining such Tax Refund,
provided, however, that the Borrower agrees to promptly return such Tax Refund
--------  -------
to such Administrative Agent or the applicable Lender, as the case may be, if it
receives notice from such Administrative Agent or applicable Lender that such
Administrative Agent or Lender is required to repay such Tax Refund but only if
such repayment is required because the initial Tax Refund was permitted in
error.

          7.14 Use of Proceeds.  The proceeds of the Loans shall be used for
               ---------------
general corporate purposes of Holdings and its Subsidiaries, including the
Transactions and acquisitions permitted hereunder; provided, that not more than
                                                   --------
U.S.$16,500,000 in aggregate principal amount of U.S. Revolving Credit Loans and
Canadian Revolving Credit Loans may be used to finance the Transactions.

          7.15 Change of Lending Office.  Each Lender agrees that, upon the
               ------------------------
occurrence of any event giving rise to the operation of Section 7.10, 7.12 or
7.13(a) with respect to such Lender, it will, if requested by Holdings, use
reasonable efforts (subject to overall policy considerations of such Lender) to
designate another lending office for any Loans affected by such event with the
object of avoiding the consequences of such event; provided, that such
                                                   --------
designation is made on terms that, in the sole judgment of such Lender, cause
such Lender and its lending office(s) to suffer no economic, legal or regulatory
disadvantage, and provided, further, that nothing in this Section shall affect
                  --------  -------
or postpone any of the obligations of any Borrower or the rights of any Lender
pursuant to Section 7.10, 7.12 or 7.13(a).

          7.16 Replacement of Lenders under Certain Circumstances.  Holdings
               --------------------------------------------------
shall be permitted to (a) replace any Lender that (i) defaults in its obligation
to make Loans hereunder, (ii) is not required to make Eurodollar Loans pursuant
to Section 7.10 or 7.11, (iii) is not required to issue Acceptances under
Section 7.10 (unless such Lender complies with Section 5.13) or (iv) in
connection with any proposed amendment, modification, supplement or waiver with
respect to any of the provisions of the Loan Documents as contemplated in
Section 15.1 where such amendment, modification, supplement or waiver has been
approved by the Required Lenders (and, if applicable, the Required Prepayment
Lenders and/or Majority Facility Lenders) in
<PAGE>

                                                                              81

accordance with such Section, fails to consent to any such proposed action and
(b) replace or remove any Lender that requests reimbursement for amounts owing
pursuant to Section 7.11 or 7.13, in each case with a replacement financial
institution and, if the Borrower elects to remove such Lender, terminate such
Lender's applicable Revolving Credit Commitment hereunder; provided that (i)
such replacement or removal does not conflict with any Requirement of Law, (ii)
no Event of Default shall have occurred and be continuing at the time of such
replacement or removal, (iii) prior to any such replacement or removal pursuant
to clause (b) above, such Lender shall have taken no action under Section 7.15
so as to eliminate the continued need for payment of amounts owing pursuant to
Section 7.11 or 7.13, (iv) the relevant Borrower shall be liable to such
replaced Lender under Section 7.12 (as though Section 7.12 were applicable) if
any Eurodollar Loan owing to such replaced Lender or Acceptance created by such
Lender shall be purchased other than on the last day of the Interest Period or
maturity date relating thereto, (v) any such replacement or removal, as the case
may be, shall not be deemed to be a waiver of any rights which the Borrower, the
Administrative Agents or any other Lender shall have against the replaced or
removed Lender, (vi) in the case of replacement of a Lender under this Section
7.16, the replacement financial institution shall purchase, at par, all Loans
and other amounts owing to such replaced Lender on or prior to the date of
replacement, (vii) the replacement financial institution, if not already a
Lender, shall be reasonably satisfactory to the General Administrative Agent,
(viii) the replaced Lender shall be obligated to make such replacement in
accordance with the provisions of Section 15.6 (provided that no registration
and processing fee referred to therein shall be required to be paid in
connection therewith), and (ix) the relevant Borrower shall pay all additional
amounts (if any) required pursuant to Section 7.11 or 7.13, as the case may be,
in respect of any period prior to the date on which such replacement shall be
consummated. If the Borrower elects to remove a Lender under clause (b) of this
Section 7.16 and if such Lender has any Loans outstanding at such time, the
consent of the General Administrative Agent and the Required Lenders shall be
required to terminate such Lender's Revolving Credit Commitment and in the case
of replacement of a non-consenting Lender under clause (a)(iii) of this Section
7.16, the Borrower shall replace such Lender within 120 days of such Lender's
failure to consent to the proposed action.

                  SECTION 8.  REPRESENTATIONS AND WARRANTIES

          To induce the Agents and the Lenders to enter into this Agreement and
to make the Loans, issue or participate in the Letters of Credit, Holdings and
the Borrowers hereby represent and warrant to each Agent and each Lender that
(it being understood that the representations and warranties of the Canadian
Borrower are made only with respect to matters relating to it):

          8.1  Financial Condition.  (a)  The unaudited pro forma consolidated
               -------------------                      --- -----
balance sheet of Holdings and its consolidated Subsidiaries as at June 30, 1999
(including the notes thereto) (the "Pro Forma Balance Sheet"), copies of which
                                    -----------------------
have heretofore been furnished to each Lender, has been prepared giving effect
(as if such events had occurred on such date) to (i) the consummation of the
Transactions, (ii) the Loans to be made and the Acceptances to be created on the
Closing Date and the use of proceeds thereof and (iii) the payment of fees and
expenses in connection with the foregoing.  The Pro Forma Balance Sheet has been
prepared based on the

best information reasonably available to the Borrower as of the date of delivery
thereof and on good faith estimates and assumptions believed to be reasonable at
the time made, and presents fairly in all material respects on a pro forma basis
                                                                 --- -----

(prior to the Transactions) as at August 31, 1997 and August 31, 1998, and the
related consolidated statements of income and of cash flows for the fiscal years
ended on such dates, reported on by and accompanied by an unqualified report
from KPMG Peat Marwick, present fairly in all material respects the consolidated
financial condition of the Canadian Borrower (prior to the Transactions) as at

consolidated balance sheet of the Canadian Borrower (prior to the Transactions)
as at June 30, 1999, and the related unaudited consolidated statements of income
for the ten-month period ended on such date, present fairly in all material
respects the consolidated financial condition of the Canadian Borrower (prior to
the Transactions) as at such date, and the consolidated results of its
operations for the ten-month period then ended (subject to normal year-end audit
adjustments and the absence of certain notes thereto).  All such financial
statements, including the related schedules and notes thereto, have been
prepared in accordance with Canadian GAAP applied consistently throughout the
periods involved (except as approved by the aforementioned firm of accountants
and disclosed therein).  Immediately prior to the consummation of the
Transactions, the Canadian Borrower does not have any material Guarantee

leases or unusual forward or long-term commitments, including, without
limitation, any interest rate or foreign currency swap or exchange transaction

period from August 31, 1998 to and including the date hereof there has been no
Disposition by the Canadian Borrower of any material part of its business or
Property, except pursuant to the Transactions.

the related consolidated statements of income and of cash flows for the fiscal

Transactions) as at such date, and the consolidated results of its operations
and its consolidated cash flows for the respective fiscal years then ended.  The
unaudited consolidated balance sheet of the U.S. Borrower (prior to the
Transactions) as at June 30, 1999, and the related unaudited consolidated
statements of income and cash flows for the six-month period ended on such date,
present fairly in all material respects the consolidated financial condition of
the U.S. Borrower (prior to the Transactions) as at such date, and the
consolidated results of its operations and its consolidated cash flows for the
six-month period then ended (subject to normal year-end audit adjustments and
the absence of certain notes thereto).  All such financial statements, including
the related schedules and notes thereto, have been prepared in accordance with
GAAP applied consistently throughout the
<PAGE>

                                                                              83

periods involved (except as approved by the aforementioned firm of accountants
and disclosed therein).  Immediately prior to the consummation of the
Transactions, the U.S. Borrower does not have any material Guarantee
Obligations, contingent liabilities and liabilities for taxes, or any long-term
leases or unusual forward or long-term commitments, including, without
limitation, any interest rate or foreign currency swap or exchange transaction

period from December 31, 1998 to and including the date hereof there has been no
Disposition by the U.S. Borrower of any material part of its business or
Property, except pursuant to the Transactions.

          8.2  No Change.  Since August 31, 1998 (in the case of the Canadian
               ---------
Borrower) and since December 31, 1998 (in the case of the U.S. Borrower) there
has been no development or event that has had or could reasonably be expected to
have a Material Adverse Effect (it being understood that the consummation of the
Transactions on the Closing Date shall not constitute or be deemed to have a
Material Adverse Effect).

          8.3  Corporate Existence; Compliance with Law.  Each of Holdings and
               ----------------------------------------
its Subsidiaries (a) is duly organized, validly existing and in good standing
under the laws of the jurisdiction of its organization, (b) has the corporate
power and authority, and the legal right, to own and operate its Property, to
lease the Property it operates as lessee and to conduct the business in which it
is currently engaged, (c) is duly qualified as a foreign corporation and in good
standing under the laws of each jurisdiction where its ownership, lease or
operation of Property or the conduct of its business requires such
qualification, except to the extent the failure to be so qualified and/or in
good standing could not reasonably be expected to have a Material Adverse Effect
and (d) is in compliance with all Requirements of Law except to the extent that
the failure to comply therewith could not, in the aggregate, reasonably be
expected to have a Material Adverse Effect.

          8.4  Corporate Power; Authorization; Enforceable Obligations.  Each
               -------------------------------------------------------
Loan Party has the corporate power and authority, and the legal right, to make,
deliver and perform the Loan Documents to which it is a party and, in the case
of each Borrower, to borrow hereunder.  Each Loan Party has taken all necessary
corporate action to authorize the execution, delivery and performance of the
Loan Documents to which it is a party and, in the case of each Borrower, to
authorize the borrowings on the terms and conditions of this Agreement.  No
consent or authorization of, filing with, notice to or other act by or in
respect of, any Governmental Authority or any other Person is required in
connection with the Transactions, the borrowings hereunder or the execution,
delivery, performance, validity or enforceability of this Agreement or any of
the other Loan Documents, except (i) consents, authorizations, filings and
notices described in Schedule 8.4, which consents, authorizations, filings and
notices have been obtained or made and are in full force and effect, (ii) other
consents required in connection with the Transactions, the failure to obtain
which could not reasonably be expected to have a Material Adverse Effect, and
(iii) the filings referred to in Section 8.19.  Each Loan Document has been duly
executed and delivered on behalf of each Loan Party that is a party thereto.
This Agreement constitutes, and each other Loan Document upon execution will
constitute, a legal, valid and binding obligation of each Loan Party that is a
party thereto, enforceable against each such Loan

                                                                              84

Party in accordance with its terms, except as enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting the enforcement of creditors' rights generally and by general
equitable principles (whether enforcement is sought by proceedings in equity or
at law).

          8.5  No Legal Bar.  The execution, delivery and performance of this
               ------------
Agreement and the other Loan Documents, the issuance of Letters of Credit, the
borrowings hereunder and the use of the proceeds thereof will not violate any
material Requirement of Law or any material Contractual Obligation of Holdings
or any of its Subsidiaries and will not result in, or require, the creation or
imposition of any Lien on any of their respective properties or revenues
pursuant to any material Requirement of Law or any such material Contractual
Obligation (other than the Liens created by the Security Documents).  No
Contractual Obligation applicable to Holdings or any of its Subsidiaries could
reasonably be expected to have a Material Adverse Effect.

          8.6  No Material Litigation.  Except as disclosed on Schedule 8.6, as
               ----------------------
of the date hereof, no litigation, investigation or proceeding of or before any
arbitrator or Governmental Authority is pending or, to the knowledge of
Holdings, threatened by or against Holdings or any of its Subsidiaries or
against any of their respective properties or revenues (a) with respect to any
of the Loan Documents or any of the transactions contemplated hereby or thereby,
or (b) that could reasonably be expected to have a Material Adverse Effect.

          8.7  No Default.  Neither Holdings nor any of its Subsidiaries is in
               ----------
default under or with respect to any of its Contractual Obligations in any
respect that could reasonably be expected to have a Material Adverse Effect.  No
Default or Event of Default has occurred and is continuing.

          8.8  Ownership of Property; Liens.  Each of Holdings and its
               ----------------------------
Subsidiaries has title in fee simple to, or a valid leasehold interest in, all
its material real property, and good title to, or a valid leasehold interest in,
all its other Property material to the conduct of its Business, and none of such
Property is subject to any Lien except as permitted by Section 11.3.

          8.9  Intellectual Property.  Holdings and each of its Subsidiaries
               ---------------------
owns, or is licensed to use, or otherwise has the right to use, all Intellectual
Property necessary for the conduct of its business as currently conducted,
except for any failure to so own, license or have the right to use Intellectual
Property which, individually or in the aggregate, could not reasonably be
expected to have a Material Adverse Effect.  No material claim has been asserted
and is pending by any Person against Holdings or any of its Subsidiaries
challenging or questioning the use of any Intellectual Property or the validity
or effectiveness of any Intellectual Property by Holdings or any of its
Subsidiaries or the validity or effectiveness of any Intellectual Property used
by Holdings or any of its Subsidiaries, except for any claims which,
individually or in the aggregate, could not reasonably be expected to have a
Material Adverse Effect.  The use of Intellectual Property by Holdings and its
Subsidiaries does not infringe on the rights of any Person in any respect which
could reasonably be expected to have a Material Adverse Effect.

               -----
or caused to be filed all Federal, state and other material tax returns that are
required to be filed and has paid all material taxes shown to be due and payable
on said returns prior to the date penalties or interest attach thereto or on any
assessments made against it or any of its Property and all other material taxes,
fees or other charges imposed on it or any of its Property by any Governmental
Authority (other than any the amount or validity of which are currently being
contested in good faith by appropriate proceedings and with respect to which
reserves in conformity with GAAP have been provided on the books of Holdings or
its Subsidiaries, as the case may be); and no tax Lien has been filed that is
not permitted by Section 11.3, and, to the knowledge of Holdings, no claim is
being asserted, with respect to any such tax, fee or other charge.

          8.11 Federal Regulations.  No part of the proceeds of any Loans will
               -------------------
be used for "purchasing" or "carrying" any "margin stock" within the respective
meanings of each of the quoted terms under Regulation U as now and from time to
time hereafter in effect or for any purpose that violates the provisions of the
Regulations of the Board.  If requested by any Lender or the General
Administrative Agent, the relevant Borrower will furnish to the Administrative
Agent and each Lender a statement to the foregoing effect in conformity with the
requirements of FR Form G-3 or FR Form U-1 referred to in Regulation U.

          8.12 Labor Matters. There are no strikes or other labor disputes
               -------------
against Holdings or any of its Subsidiaries pending or, to the knowledge of
Holdings, threatened that (individually or in the aggregate) could reasonably be
expected to have a Material Adverse Effect.  Hours worked by and payment made to
employees of Holdings and its Subsidiaries have not been in violation of the
Fair Labor Standards Act or any other applicable Requirement of Law dealing with
such matters that (individually or in the aggregate) could reasonably be
expected to have a Material Adverse Effect.  All payments due from Holdings or
any of its Subsidiaries on account of employee health and welfare insurance that
(individually or in the aggregate) could reasonably be expected to have a
Material Adverse Effect if not paid have been paid or accrued as a liability on
the books of Holdings or the relevant Subsidiary.

          8.13 ERISA.  Neither a Reportable Event nor an "accumulated funding
               -----
deficiency" (within the meaning of Section 412 of the Code or Section 302 of
ERISA) has occurred during the five-year period prior to the date on which this
representation is made or deemed made with respect to any Plan, and each Plan
has complied in all material respects with the applicable provisions of ERISA
and the Code.  No termination of a Single Employer Plan has occurred, and no
Lien in favor of the PBGC or a Plan has arisen, during such five-year period.
The present value of all accrued benefits under each Single Employer Plan (based
on those assumptions used to fund such Plans) did not, as of the last annual
valuation date prior to the date on which this representation is made or deemed
made, exceed the value of the assets of such Plan allocable to such accrued
benefits by a material amount.  Neither Holdings nor any Commonly Controlled
Entity has had a complete or partial withdrawal from any Multiemployer Plan that
has resulted or could reasonably be expected to result in a material liability
under ERISA, and neither Holdings nor any Commonly Controlled Entity would
become subject to any material liability under ERISA if the Borrower or any such
Commonly Controlled Entity were to withdraw completely from all Multiemployer
Plans as of the valuation date most closely preceding the date

                                                                              86

on which this representation is made or deemed made.  No such Multiemployer Plan
is in Reorganization or Insolvent.

          8.14 Investment Company Act; Other Regulations.  No Loan Party is an
               -----------------------------------------
"investment company", or a company "controlled" by an "investment company",
within the meaning of the Investment Company Act of 1940, as amended.  No Loan
Party is subject to regulation under any Requirement of Law (other than
Regulation X of the Board) which limits its ability to incur Indebtedness.

          8.15 Subsidiaries.  The Subsidiaries listed on Schedule 8.15
               ------------
constitute all the Subsidiaries of Holdings at the date hereof.  Schedule 8.15
sets forth as of the Closing Date the name and jurisdiction of incorporation of
each Subsidiary and, as to each Subsidiary, the percentage of each class of
Capital Stock owned by each Loan Party.

          8.16 Use of Proceeds.  The proceeds of the Loans shall be used for
               ---------------
the purposes set forth in Section 7.14.

          8.17 Environmental Matters.  Other than exceptions to any of the
               ---------------------

     without limitation, any location to which Materials of Environmental
     Concern have been sent for re-use or recycling or for treatment, storage,
     or disposal) which could reasonably be expected to (i) give rise to
     liability of Holdings or any of its Subsidiaries under any applicable
     Environmental Law or otherwise result in costs to Holdings or any of its
     Subsidiaries, or (ii) interfere with Holdings or any of its Subsidiaries'
     continued operations, or (iii) impair the fair saleable value of any real
     property owned or leased by Holdings or any of its Subsidiaries.

     as a party that is pending or, to the knowledge of Holdings or any of its
     Subsidiaries, threatened.

          (d)  Neither Holdings nor any of its Subsidiaries has received any
     written request for information, or been notified that it is a potentially
     responsible party under or relating to the federal Comprehensive
     Environmental Response, Compensation, and Liability Act or any similar
     Environmental Law, or with respect to any Materials of Environmental
     Concern.

     agreed to any consent decree, order, or settlement or other agreement, or
     is subject to any judgment, decree, or order or other agreement, in any
     judicial, administrative, arbitral, or other forum for dispute resolution,
     relating to compliance with or liability under any Environmental Law.

          (f)  Neither Holdings nor any of its Subsidiaries has assumed or
     retained, by contract or operation of law, any liabilities of any kind,
     fixed or contingent, known or unknown, under any Environmental Law or with
     respect to any Material of Environmental Concern.

          8.18 Accuracy of Information, etc.  Subject to the next succeeding
               ----------------------------
sentence and to the qualification provided therein, no statement or information
contained in this Agreement, any other Loan Document, the Confidential
Information Memorandum or any other document, certificate or statement furnished
to any Agent or the Lenders or any of them, by or on behalf of any Loan Party
for use in connection with the transactions contemplated by this Agreement or
the other Loan Documents, contained as of the date such statement, information,
document or certificate was so furnished (or, in the case of the Confidential
Information Memorandum, as of the date of this Agreement), any untrue statement
of a material fact or omitted to state a material fact necessary in order to
make the statements contained herein or therein not misleading in light of the
circumstances under which they were made.  The projections and pro forma
                                                               --- -----
financial information contained in the materials referenced above are based upon
good faith estimates and assumptions believed by management of Holdings to be
reasonable at the time made, it being recognized by the Lenders that such
financial information as it relates to future events is not to be viewed as fact
and that actual results during the period or periods covered by such financial
information may differ from the projected results set forth therein by a
material amount. As of the date hereof, the representations and warranties of
each of the Loan Parties and, to the best knowledge of the Borrowers, each of
the other parties thereto contained in the Transaction Documentation are true
and correct in all material respects. There is no fact known to any Loan Party
that could reasonably be expected to have a Material Adverse Effect that has not

by the other Loan Documents.

          8.19 Security Documents.  (a)  The Guarantee and Collateral Agreement
               ------------------
is effective to create in favor of the General Administrative Agent, for the
benefit of the Lenders, a legal, valid and enforceable security interest in the
Collateral described therein and proceeds thereof.  In the case of the Pledged
Stock described in the Guarantee and Collateral Agreement, when any stock
certificates representing such Pledged Stock are delivered to the General
Administrative Agent, and in the case of the other Collateral described in the
Guarantee and Collateral Agreement, when financing statements in appropriate
form are filed in the offices specified on Schedule 8.19(a)-1 (which financing
statements have been duly completed and executed and delivered to the General
Administrative Agent) and such other filings as are specified on Schedule 3 to
the Guarantee and Collateral Agreement (all of which filings have been duly
completed), the Guarantee and Collateral Agreement shall constitute a fully
perfected Lien on, and security interest in, all right, title and interest of
the Loan Parties in such Collateral and the proceeds thereof, as security for
the Obligations (as defined in the Guarantee and Collateral Agreement), in each
case prior and superior in right to any other Person (except, in the case of
Collateral other than Pledged Stock, Liens permitted by Section 11.3).  Schedule
8.19(a)-2 lists each UCC Financing Statement that (i) names any Loan Party as
debtor and (ii) will remain on file after the Closing Date.  Schedule 8.19(a)-3

statements, signed by the relevant secured party, in respect of each UCC
Financing Statement listed in Schedule 8.19(a)-3.

          (b)  Each Canadian Security Document is effective to create in favor
of the General Administrative Agent, for the benefit of the Canadian Lenders, a
legal, valid and enforceable security interest in the Collateral described
therein and proceeds thereof.  In the case of the Pledged Stock described in the
Canadian Security Documents, when any stock certificates representing such
Pledged Stock are delivered to the General Administrative Agent, and in the case
of the other Collateral described in the Canadian Security Documents, when
financing statements or other registrations specified in Schedule 8.19(b)-1 are
registered in the offices specified therein, the Canadian Security Documents
shall constitute a fully perfected Lien on, and security interest in, all right,
title and interest of the Loan Parties in such Collateral and the proceeds
thereof, as security for the Canadian Borrower Obligations in each case prior
and superior in right to any other Person (except, in the case of Collateral
other than Pledged Stock, Liens permitted by Section 11.3).  Schedule 8.19(b)-2
lists each registered financing statement or other registration made under the
Personal Property Security Act (Ontario) ("PPSA") and similar legislation in

Closing Date. Schedule 8.19(b)-3 lists each registered financing statement or
other registration made under the PPSA and similar legislation in effect in each
of the other provinces of Canada and under The Bank Act (Canada) that (i) names
any Loan Party as debtor and (ii) will be discharged on or prior to the Closing
Date; and on or prior to the Closing Date, the Canadian Borrower will have
delivered to the Canadian Administrative Agent, or caused to be filed, duly
completed financing

form satisfactory to the Canadian Administrative Agent signed by the relevant
secured party, in respect of each registered financing statement listed in

year 2000, of (i) the Borrowers' computer systems and (ii) equipment containing
embedded microchips (including systems and equipment supplied by others or with

Borrower when due (whether at the stated maturity, by acceleration or otherwise)
of the Canadian Borrower Obligations.

          (b)  The U.S. Borrower further agrees to pay any and all expenses
(including, without limitation, all reasonable fees and disbursements of counsel
which may be paid or incurred by the Canadian Administrative Agent, or any
Canadian Lender in enforcing, or obtaining advice of counsel in respect of, any
rights with respect to, or collecting, any or all of the Canadian Borrower
Obligations and/or enforcing any rights with respect to, or collecting against,
the U.S. Borrower under this Section.  This Section shall remain in full force
and effect until the Obligations are paid in full and the Commitments are
terminated, notwithstanding that from time to time prior thereto any Borrower
may be free from any Canadian Borrower Obligations.

          (c)  No payment or payments made by any Borrower or any other Person
or received or collected by the Administrative Agents or any Lender from any
Borrower or any other Person by virtue of any action or proceeding or any set-
off or appropriation or application, at any time or from time to time, in
reduction of or in payment of the Canadian Borrower Obligations shall be deemed
to modify, reduce, release or otherwise affect the liability of the U.S.
Borrower hereunder which shall, notwithstanding any such payment or payments,
remain liable hereunder for the Canadian Borrower Obligations until the Canadian
Borrower Obligations are paid in full and the Commitments are terminated.

          (d)  The U.S. Borrower agrees that whenever, at any time, or from time
to time, it shall make any payment to any Administrative Agent or any Lender on
account of its liability hereunder, it will notify such Administrative Agent and
such Lender in writing that such payment is made under this Section for such
purpose.

          (e)  Anything herein or in any other Loan Document to the contrary
notwithstanding, the maximum liability of the U.S. Borrower hereunder and under
the other Loan Documents in respect of the Canadian Borrower Obligations shall
in no event exceed the amount which can be guaranteed by the U.S. Borrower under

          12.2  No Subrogation.  Notwithstanding any payment or payments made by
                --------------
the U.S. Borrower hereunder, or any set-off or application of funds of the U.S.
Borrower by any Administrative Agent or any Lender, the U.S. Borrower shall not
be entitled to be subrogated to any of the rights of any Administrative Agent or
any Lender against the other Borrowers or against any collateral security or
guarantee or right of offset held by any Administrative Agent or any Lender for
the payment of the Canadian Borrower Obligations, nor shall the U.S. Borrower
seek or be entitled to seek any contribution or reimbursement from the other
Borrowers in respect of payments made by the U.S. Borrower hereunder, until all
amounts owing to the Administrative Agents and the Lenders by the other

the Commitments are terminated.  If any amount shall be paid to the U.S.
Borrower on account of such subrogation rights at any time when all of the
Canadian Borrower Obligations shall not have been paid in full, such amount
shall be held by the U.S. Borrower in trust for the Administrative Agents and
the Lenders, segregated from other funds of

the U.S. Borrower, and shall, forthwith upon receipt by the U.S. Borrower, be
turned over to the Canadian Administrative Agent in the exact form received by
the U.S. Borrower (duly indorsed by the U.S. Borrower to the Canadian
Administrative Agent, if required), to be applied against the Canadian Borrower
Obligations, whether matured or unmatured, in such order as the Canadian
Administrative Agent may determine.

          12.3  Amendments, etc. with respect to the Canadian Borrower
                ------------------------------------------------------
Obligations; Waiver of Rights.  The U.S. Borrower shall remain obligated
-----------------------------
hereunder notwithstanding that, without any reservation of rights against the
U.S. Borrower, and without notice to or further assent by the U.S. Borrower, any
demand for payment of any of the Canadian Borrower Obligations made by any
Administrative Agent or any Lender may be rescinded by such Administrative Agent
or such Lender, and any of the Canadian Borrower Obligations continued, and the
Canadian Borrower Obligations, or the liability of any other party upon or for
any part thereof, or any collateral security or guarantee therefor or right of
offset with respect thereto, may, from time to time, in whole or in part, be
renewed, extended, amended, modified, accelerated, compromised, waived,
surrendered or released by any Administrative Agent or any Lender, and any Loan
Documents and any other documents executed and delivered in connection therewith
may be amended, modified, supplemented or terminated, in whole or in part, in
accordance with the provisions thereof as the Administrative Agents or the
Lenders (or the Required Lenders, as the case may be) may deem advisable from
time to time, and any collateral security, guarantee or right of offset at any
time held by any Administrative Agent or any Lender for the payment of the
Canadian Borrower Obligations may be sold, exchanged, waived, surrendered or
released.  None of any Administrative Agent or any Lender shall have any
obligation to protect, secure, perfect or insure any Lien at any time held by it
as security for the Canadian Borrower Obligations or for this Agreement or any
property subject thereto.  When making any demand hereunder against the U.S.
Borrower, any Administrative Agent or any Lender may, but shall be under no
obligation to, make a similar demand on any other Borrower or any other
guarantor, and any failure by any Administrative Agent or any Lender to make any
such demand or to collect any payments from any such Borrower or any such other
guarantor or any release of such Borrower or such other guarantor shall not
relieve the U.S. Borrower of its obligations or liabilities hereunder, and shall
not impair or affect the rights and remedies, express or implied, or as a matter
of law, of any Administrative Agent or any Lender against the U.S. Borrower.
For the purposes hereof "demand" shall include the commencement and continuance
of any legal proceedings.

          12.4  Guarantee Absolute and Unconditional.  The U.S. Borrower waives
                ------------------------------------
any and all notice of the creation, renewal, extension or accrual of any of the
Canadian Borrower Obligations and notice of or proof of reliance by any
Administrative Agent or any Lender upon this Agreement or acceptance of this
Agreement; the Canadian Borrower Obligations, and any of them, shall
conclusively be deemed to have been created, contracted or incurred, or renewed,
extended, amended or waived, in reliance upon this Agreement; and all dealings
between the Borrowers and the U.S. Borrower and the Canadian Borrower, on the
one hand, and the Administrative Agents and the Lenders, on the other, shall
likewise be conclusively presumed to have been had or consummated in reliance
upon this Agreement.  The U.S. Borrower waives diligence, presentment, protest,
demand for payment and notice of default or nonpayment to or

                                                                             118

upon the other Borrowers and the U.S. Borrower with respect to the Canadian
Borrower Obligations.  This Section 12 shall be construed as a continuing,
absolute and unconditional guarantee of payment without regard to (a) the
validity or enforceability of this Agreement, any other Loan Document, any of
the Canadian Borrower Obligations or any other collateral security therefor or
guarantee or right of offset with respect thereto at any time or from time to
time held by any Administrative Agent or any Lender, (b) any defense, set-off or
counterclaim (other than a defense of payment or performance) which may at any
time be available to or be asserted by the Canadian Borrower against any
Administrative Agent or any Lender, or (c) any other circumstance whatsoever
(with or without notice to or knowledge of the Canadian Borrower or the U.S.
Borrower) which constitutes, or might be construed to constitute, an equitable
or legal discharge of the Canadian Borrower for the Canadian Borrower
Obligations, or of the U.S. Borrower under this Section 12, in bankruptcy or in
any other instance.  When pursuing its rights and remedies hereunder against the
U.S. Borrower, any Administrative Agent and any Lender may, but shall be under
no obligation to, pursue such rights and remedies as it may have against the
Canadian Borrower or any other Person or against any collateral security or
guarantee for the Canadian Borrower Obligations or any right of offset with
respect thereto, and any failure by any Administrative Agent or any Lender to
pursue such other rights or remedies or to collect any payments from such other
Borrowers or any such other Person or to realize upon any such collateral
security or guarantee or to exercise any such right of offset, or any release of
the other Borrower or any such other Person or of any such collateral security,
guarantee or right of offset, shall not relieve the U.S. Borrower of any
liability hereunder, and shall not impair or affect the rights and remedies,
whether express, implied or available as a matter of law, of any Administrative
Agent or any Lender against the U.S. Borrower.  This Section 12 shall remain in
full force and effect and be binding in accordance with and to the extent of its
terms upon the U.S. Borrower and its successors and assigns, and shall inure to
the benefit of the Administrative Agents and the Lenders, and their respective
successors, indorsees, transferees and assigns, until all the Canadian Borrower
Obligations and the obligations of the U.S. Borrower under this Agreement shall
have been satisfied by payment in full and the Commitments shall be terminated,
notwithstanding that from time to time during the term of this Agreement the
Borrowers may be free from any Canadian Borrower Obligations.

          12.5  Reinstatement.  This Section 12 shall continue to be effective,
                -------------
or be reinstated, as the case may be, if at any time payment, or any part
thereof, of any of the Canadian Borrower Obligations is rescinded or must
otherwise be restored or returned by any Administrative Agent or any Lender upon
the insolvency, bankruptcy, dissolution, liquidation or reorganization of any
Borrower or upon or as a result of the appointment of a receiver, intervenor or
conservator of, or trustee or similar officer for, any Borrower or any
substantial part of its property, or otherwise, all as though such payments had
not been made.

          12.6  Payments.  The U.S. Borrower hereby agrees that all payments
                --------
required to be made by it hereunder will be made to the Canadian Administrative
Agent, for the benefit of the Administrative Agents and the Lenders, as the case
may be, without set-off or counterclaim in accordance with the terms of the
Canadian Borrower Obligations, including, without limitation, in the currency in
which payment is due.

Administrative Agent may, or upon the request of the Required Lenders, the
General Administrative Agent shall, by notice to the Borrowers declare the
Commitments to be terminated forthwith, whereupon the Commitments shall
immediately terminate; (ii) with the consent of the Required Lenders, the
General Administrative Agent may, or upon the direction of the Required Lenders,
the General Administrative Agent shall, by notice of default to the Borrowers,
declare the Loans hereunder (with accrued interest thereon) and all other
amounts owing under this Agreement (including all amounts payable in respect of
Letters of Credit whether or not the beneficiaries thereof shall have presented
the drafts and other documents required thereunder) and the Notes to be due and
payable forthwith, whereupon the same shall immediately become due and payable
and (iii) the General Administrative Agent may, and upon the direction of the
Required Lenders shall, exercise any and all remedies and other rights provided
pursuant to this Agreement and/or the other Loan Documents.

          With respect to all outstanding Reimbursement Obligations which have
not matured at the time of an acceleration pursuant to the second preceding
paragraph, the relevant Borrower shall at such time deposit in a cash collateral
account opened by and maintained by the relevant Administrative Agent an amount
equal to the aggregate amount of all such Reimbursement Obligations.  Amounts
held in such cash collateral account shall be applied by an Administrative Agent
to the payment of Reimbursement Obligations when drawings under the related
Letters of Credit are made, and any balance in such account shall be applied to
repay other obligations of the relevant Borrower hereunder.  After all
Reimbursement Obligations shall have been satisfied and all other obligations of
the Borrowers hereunder shall have been paid in full, the balance, if any, in
such cash collateral account shall be returned to the relevant Borrower.

          With respect to all outstanding Acceptance Reimbursement Obligations
in respect of Acceptances which have not matured at the time of an acceleration
pursuant to the second preceding paragraph, the Canadian Borrower shall at such
time deposit in a cash collateral account opened by and maintained by the
Canadian Administrative Agent an amount equal to the aggregate undiscounted face
amount of all such unmatured Acceptances.  Amounts held in such cash collateral
account shall be applied by the Canadian Administrative Agent to the payment of
maturing Acceptances, and any balance in such account shall be applied to repay
other obligations of the Canadian Borrower hereunder and under any Notes.  After
all Acceptance Reimbursement Obligations shall have been satisfied and all other
obligations of the Canadian Borrower hereunder

                                                                             123

and under any Notes shall have been paid in full, the balance, if any, in such
cash collateral account shall be returned to the Canadian Borrower.

          Except as expressly provided above in this Section, presentment,
demand, protest and all other notices of any kind are hereby expressly waived.

          SECTION 14.  THE AGENTS; THE ARRANGER

          14.1  Appointment.  Each Lender hereby irrevocably designates and
                -----------
appoints the Agents as agents of such Lender under this Agreement and the other
Loan Documents, and each Lender irrevocably authorizes each Agent, in such
capacity, to take such action on its behalf under the provisions of this
Agreement and the other Loan Documents and to exercise such powers and perform
such duties as are expressly delegated to such Agent by the terms of this
Agreement and the other Loan Documents, together with such other powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
elsewhere in this Agreement, the Agents shall not have any duties or
responsibilities, except those expressly set forth herein, or any fiduciary
relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against any Agent.

          14.2  Delegation of Duties.  Each Agent may execute any of its duties
                --------------------
under this Agreement and the other Loan Documents by or through agents or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties.  No Agent shall be responsible for the
negligence or misconduct of any agents or attorneys-in-fact selected by it with
reasonable care.

          14.3  Exculpatory Provisions.  Neither any Agent nor any of its
                ----------------------
respective officers, directors, employees, agents, attorneys-in-fact or
affiliates shall be (i) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or any
other Loan Document (except for its or such Person's gross negligence or willful
misconduct) or (ii) responsible in any manner to any of the Lenders for any
recitals, statements, representations or warranties made by any Borrower or
other Person or any officer thereof contained in this Agreement or any other
Loan Document or in any certificate, report, statement or other document
referred to or provided for in, or received by such Agent under or in connection
with, this Agreement or any other Loan Document or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any other Loan Document or for any failure of a Borrower or any other Person to
perform its obligations hereunder or thereunder.  No Agent shall be under any
obligation to any Lender to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this
Agreement or any other Loan Document or to inspect the properties, books or
records of the Borrowers.

          14.4  Reliance by Agents.  Each Agent shall be entitled to rely, and
                ------------------
shall be fully protected in relying, upon any Note, writing, resolution, notice,
consent, certificate, affidavit, letter, telecopy, telex or teletype message,
statement, order or other document or conversation believed by it to be genuine
and correct and to have been signed, sent or made by the proper
<PAGE>

                                                                             124

Person or Persons and upon advice and statements of legal counsel (including,
without limitation, counsel to the Borrowers or either of them), independent
accountants and other experts selected by such Agent.  Each Agent may deem and
treat the payee of any Note as the owner thereof for all purposes unless a
written notice of assignment or transfer thereof shall have been filed with such
Agent.  Each Agent shall be fully justified as between itself and the Lenders in
failing or refusing to take any action under this Agreement or any other Loan
Document unless it shall first receive such advice or concurrence of the
Required Lenders as it deems appropriate or it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action.
Each Agent shall in all cases be fully protected in acting, or in refraining
from acting, under this Agreement and the other Loan Documents in accordance
with a request of the Required Lenders, and such request and any action taken or
failure to act pursuant thereto shall be binding upon all the Lenders and all
future holders of the Loans, the Reimbursement Obligations and the Acceptance
Reimbursement Obligations.

          14.5  Notice of Default.  No Agent shall be deemed to have knowledge
                -----------------
or notice of the occurrence of any Default or Event of Default hereunder unless
such Agent has received notice from a Lender or a Borrower referring to this
Agreement, describing such Default or Event of Default and stating that such
notice is a "notice of default".  In the event that the General Administrative
Agent receives such a notice, the General Administrative Agent shall give notice
thereof to the Lenders.  The General Administrative Agent shall take such action
reasonably promptly with respect to such Default or Event of Default as shall be
reasonably directed by the Required Lenders; provided that unless and until the
General Administrative Agent shall have received such directions, the General
Administrative Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable in the best interests of the Lenders.

          14.6  Non-Reliance on Agents and Other Lender.  Each Lender expressly
                ---------------------------------------
acknowledges that neither any Agent nor any of its respective officers,
directors, employees, agents, attorneys-in-fact or affiliates has made any
representations or warranties to it and that no act by such Agent hereafter
taken, including any review of the affairs of either Borrower, shall be deemed
to constitute any representation or warranty by such Agent to any Lender.  Each
Lender represents to each Agent that it has, independently and without reliance
upon such Agent or any other Lender, and based on such documents and information
as it has deemed appropriate, made its own appraisal of and investigation into
the business, operations, property, financial and other condition and
creditworthiness of the Borrowers and made its own decision to make its
Extensions of Credit hereunder and enter into this Agreement.  Each Lender also
represents that it will, independently and without reliance upon either any
Agent or any other Lender, and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents, and to make such investigation as it deems necessary
to inform itself as to the business, operations, property, financial and other
condition and creditworthiness of the Borrowers.  Except for notices, reports
and other documents expressly required to be furnished to the Lenders by an
Agent hereunder, such Agent shall not have any duty or responsibility to provide
any Lender with any credit or other information concerning the business,
<PAGE>

                                                                             125

operations, property, condition (financial or otherwise), prospects or
creditworthiness of the Borrowers which may come into the possession of such
Agent or any of its respective officers, directors, employees, agents,
attorneys-in-fact or affiliates.

          14.7  Indemnification.  Each Lender agrees to indemnify each Agent in
                ---------------
its capacity as such (to the extent not reimbursed by the Borrowers and without
limiting the obligation of the Borrowers to do so), ratably according to its
Aggregate Exposure Percentage in effect on the date on which indemnification is
sought from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind whatsoever which may at any time (including, without limitation, at any
time following the payment of the Loans, the Reimbursement Obligations and the
Acceptance Reimbursement Obligations) be imposed on, incurred by or asserted
against such Agent in any way relating to or arising out of this Agreement, any
of the other Loan Documents or any documents contemplated by or referred to
herein or therein or the transactions contemplated hereby or thereby or any
action taken or omitted by such Agent under or in connection with any of the
foregoing; provided that no Lender shall be liable for the payment of any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the gross
negligence or willful misconduct of such Agent.  The agreements in this
subsection shall survive the payment of the Loans, the Acceptance Reimbursement
Obligations, the Reimbursement Obligations and all other amounts payable
hereunder.

          14.8  Agents in their Individual Capacity.  Each Agent and its
                -----------------------------------
respective affiliates may make loans to, accept Drafts, accept deposits from and
generally engage in any kind of business with the Borrowers as though such Agent
was not an Agent hereunder and under the other Loan Documents.  With respect to
the Loans made or renewed by such Agent, any Acceptances created by such Agent
and any Note or Acceptance Note issued to it, such Agent shall have the same
rights and powers under this Agreement and the other Loan Documents as any
Lender and may exercise the same as though it were not an Agent, and the terms
"Lender" and "Lenders" shall include each Agent in its individual capacity.

          14.9  Successor Agents.  The General Administrative Agent may resign
                ----------------
as General Administrative Agent, the Canadian Administrative Agent may resign as
Canadian Administrative Agent and the Collateral Monitoring Agent may resign as
the Collateral Monitoring Agent, in each case upon 30 days' notice to the
Lenders and the other Agents.  If any Agent shall resign as Agent under this
Agreement and the other Loan Documents, then the Required Lenders shall appoint
from among the U.S. Lenders (in the case of a resignation of the General
Administrative Agent or the Collateral Monitoring Agent) or the Canadian Lenders
(in the case of a resignation of the Canadian Administrative Agent) a successor
agent for the Lenders, whereupon such successor agent shall succeed to the
rights, powers and duties of the resigning Agent, and the terms "General
Administrative Agent", "Canadian Administrative Agent" or "Collateral Monitoring
Agent", as the case may be, shall mean such successor agent effective upon such
appointment and approval, and the former Agent's rights, powers and duties as
such Agent shall be terminated, without any other or further act or deed on the
part of such former Agent or any of the parties to this Agreement or any holders
of the Loans.  After any resigning Agent's resignation, the provisions of this
Section 14 shall inure to its benefit as to any actions taken or

<PAGE>

                                                                             126

omitted to be taken by it while it was an Agent under this Agreement and the
other Loan Documents.

          14.10  The Documentation Agent, the Arranger and the Syndication
                 ---------------------------------------------------------
Agents.  Each Lender, the Documentation Agent, the Arranger and the Syndication
------
Agent acknowledge that the Documentation Agent, the Arranger and the Syndication
Agent, in such capacities, shall have no duties or responsibilities, and shall
incur no liabilities, under this Agreement or the other Loan Documents in their
respective capacities as such.

          14.11  Authorization to Release Liens and Guarantees.  Each
                 ---------------------------------------------
Administrative Agent is hereby irrevocably authorized by each of the Lenders to
effect any release of Liens or guarantee obligations contemplated by Section
15.15.

                          SECTION 15.  MISCELLANEOUS

          15.1  Amendments and Waivers.  Neither this Agreement or any other
                ----------------------
Loan Document, nor any terms hereof or thereof may be amended, supplemented or
modified except in accordance with the provisions of this Section 15.1.  The
Required Lenders and each Loan Party party to the relevant Loan Document may, or
the General Administrative Agent (with the written consent of the Required
Lenders) and each Loan Party party to the relevant Loan Document may, from time
to time, (a) enter into written amendments, supplements or modifications hereto
and to the other Loan Documents (including amendments and restatements hereof or
thereof) for the purpose of adding any provisions to this Agreement or the other
Loan Documents or changing in any manner the rights of the Lenders or of the
Loan Parties hereunder or thereunder or (b) waive, on such terms and conditions
as may be specified in the instrument of waiver, any of the requirements of this
Agreement or the other Loan Documents or any Default or Event of Default and its
consequences; provided, however, that no such waiver and no such amendment,
              --------  -------
supplement or modification shall:

          (i)   forgive the principal amount or extend the final scheduled date
     of maturity of any Loan, Reimbursement Obligation or Acceptance
     Reimbursement Obligation, extend the scheduled date of any amortization
     payment in respect of any Term Loan, reduce the stated rate of any interest
     or fee payable hereunder or extend the scheduled date of any payment
     thereof, or increase the amount or extend the expiration date of any
     Commitment of any Lender, in each case without the consent of each Lender
     directly affected thereby;

          (ii)  amend, modify or waive any provision of this Section or reduce
     any percentage specified in the definition of Required Lenders or Required
     Prepayment Lenders consent to the assignment or transfer by any Borrower of
     any of its rights and obligations under this Agreement and the other Loan
     Documents, release all or substantially all of the Collateral or release
     all or substantially all of the Subsidiary Guarantors from their guarantee
     obligations under the Guarantee and Collateral Agreement or all or

     Canadian Facility Guarantees, in each case without the consent of all
     Lenders, except as otherwise provided in this Agreement or any other Loan
     Document;
<PAGE>

                                                                             127

          (iii)  amend, modify or waive any condition precedent to any extension
     of credit under the U.S. Revolving Credit Facility or the Canadian
     Revolving Credit Facility set forth in Section 9.2 (including, without
     limitation, the waiver of an existing Default or Event of Default required
     to be waived in order for such extension of credit to be made), or change
     the Advance Rate, without the consent of the Majority Facility Lenders
     under the relevant Facility;

          (iv)   reduce the percentage specified in the definition of Majority
     Facility Lenders with respect to any Facility without the written consent
     of all Lenders under such Facility; (v) amend, modify or waive any
     provision of Section 14 without the consent of any Agent directly affected
     thereby;

          (vi)   amend, modify or waive any provision of Section 2.6 or 2.7
     without the written consent of the Swing Line Lender;

          (vii)  amend, modify or waive any provision of Section 7.9 without the
     consent of each Lender directly affected thereby; or

          (viii) amend, modify or waive any provision of Section 6 without the
     consent of each Issuing Lender directly affected thereby.

Any such waiver and any such amendment, supplement or modification shall apply
equally to each of the Lenders and shall be binding upon the Loan Parties, the
Lenders, the Agents and all future holders of the Loans.  In the case of any
waiver, the Loan Parties, the Lenders and the Agents shall be restored to their
former position and rights hereunder and under the other Loan Documents, and any
Default or Event of Default waived shall be deemed to be cured and not
continuing; but no such waiver shall extend to any subsequent or other Default
or Event of Default, or impair any right consequent thereon.  Any such waiver,
amendment, supplement or modification shall be effected by a written instrument
signed by the parties required to sign pursuant to the foregoing provisions of
this Section; provided, that delivery of an executed signature page of any such
              --------
instrument by facsimile transmission shall be effective as delivery of a
manually executed counterpart thereof.

          For the avoidance of doubt, this Agreement may be amended (or amended
and restated) with the written consent of the Required Lenders, the Agents and
each Loan Party to each relevant Loan Document (x) to add one or more additional
credit facilities to this Agreement and to permit the extensions of credit from
time to time outstanding thereunder and the accrued interest and fees in respect
thereof (collectively, the "Additional Extensions of Credit") to share ratably
                            -------------------------------
in the benefits of this Agreement and the other Loan Documents with the Loans
and other Extensions of Credit and the accrued interest and fees in respect
thereof and (y) to include appropriately the Lenders holding such credit
facilities in any determination of the  Required Lenders, Required Prepayment
Lenders and Majority Facility Lenders; provided, however, that no such amendment
                                       --------  -------
shall permit the Additional Extensions of Credit to share ratably with or with
preference to the Loans in the application of mandatory prepayments without the
consent of the Required Prepayment Lenders.

                ------------------------------
delay in exercising, on the part of the any Agent or any Lender, any right,
remedy, power or privilege hereunder or under the other Loan Documents shall

statement delivered pursuant hereto or in connection herewith shall survive the
execution and delivery of this Agreement and the making of the Loans and other
extensions of credit hereunder.

          15.5  Payment of Expenses.  The Borrowers jointly and severally agree
                -------------------
(a) to pay or reimburse the Agents for all their reasonable out-of-pocket costs
and expenses incurred in connection with the syndication of the Facilities
(other than fees payable to syndicate members) and the development, preparation
and execution of, and any amendment, supplement or modification to, this
Agreement and the other Loan Documents and any other documents prepared in
connection herewith or therewith, and the consummation and administration of the
transactions contemplated hereby and thereby, including, without limitation, the
reasonable fees and disbursements of counsel to the Agents, (b) to pay or
reimburse each Lender and the Agents for all their costs and expenses incurred
in connection with the enforcement or preservation of any rights under this
Agreement, the other Loan Documents and any such other documents, including,
without limitation, the fees and disbursements of counsel (including the
allocated fees and disbursements of in-house counsel) to each Lender and of
counsel to the Agents, (c) to pay, indemnify, or reimburse each Lender and the
Agents for, and hold each Lender and the Agents harmless from, any and all
recording and filing fees and any and all liabilities with respect to, or
resulting from any delay in paying, stamp, excise (other than excise taxes
imposed in lieu of income taxes) and other similar taxes, if any, which may be
payable or determined to be payable in connection with the execution and
delivery of, or consummation or administration of any of the transactions
contemplated by, or any amendment, supplement or modification of, or any waiver
or consent under or in respect of, this Agreement, the other Loan Documents and
any such other documents, and (d) to pay, indemnify or reimburse each Lender,
each Agent, their respective affiliates, and their respective officers,
directors, trustees, employees, advisors, agents and controlling persons (each,
an "Indemnitee") for, and hold each Indemnitee harmless from and against any and
    ----------
all other liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever with respect to the execution, delivery, enforcement, performance and
administration of this Agreement, the other Loan Documents and any such other
documents, including, without limitation, any of the foregoing relating to the
use of proceeds of the Loans or the violation of, noncompliance with or
liability under, any Environmental Law applicable to the operations of either
Borrower any of its Subsidiaries or any of the Properties and the fees and
disbursements of legal counsel in connection with successful claims, actions or
proceedings by any Indemnitee against either Borrower hereunder (all the
foregoing in this clause (d), collectively, the "Indemnified Liabilities"),
                                                 -----------------------
provided, that the Borrowers shall have no obligation hereunder to any
--------
Indemnitee with respect to Indemnified Liabilities to the extent such
Indemnified Liabilities (i) are found by a final and nonappealable decision of a
court of competent jurisdiction to have resulted from the gross negligence or
willful misconduct of such Indemnitee or (ii) arise from disputes among the
Agents, among the Lenders or between the Agents and the Lenders.  Without
limiting the foregoing, and to the extent permitted by applicable law, each
Borrower agrees not to assert and to cause its Subsidiaries not to assert, and
hereby waives and agrees to cause its Subsidiaries so to waive, all rights for
contribution or any other rights of recovery with respect to all claims,
demands, penalties, fines, liabilities, settlements, damages, costs and expenses
of whatever kind or nature, under or related to Environmental Laws, that any of
them might have by statute or otherwise against any Indemnitee.  All amounts due

                                                                             131

days after written demand therefor.  Statements payable by the Borrowers
pursuant to this Section shall be submitted to the Borrowers at the address of
the U.S. Borrower set forth in Section 15.2, or to such other Person or address
as may be hereafter designated by the U.S. Borrower in a written notice to the
General Administrative Agent. The agreements in this Section shall survive
repayment of the Loans and all other amounts payable hereunder.

          15.6  Successors and Assigns; Participations and Assignments.  (a)
                ------------------------------------------------------
This Agreement shall be binding upon and inure to the benefit of Holdings, the
Borrowers, the Lenders, the Agents, all future holders of the Loans and their
respective successors and assigns, except that neither Holdings nor any Borrower
may assign or transfer any of its rights or obligations under this Agreement
without the prior written consent of the Agents and each Lender.

          (b)  Any Lender may, without the consent of Holdings or either
Borrower, in accordance with applicable law, at any time sell to one or more
banks, financial institutions or other entities (each, a "Participant")
                                                          -----------
participating interests in any Loan owing to such Lender, any Commitment of such
Lender or any other interest of such Lender hereunder and under the other Loan
Documents.  In the event of any such sale by a Lender of a participating
interest to a Participant, such Lender's obligations under this Agreement to the
other parties to this Agreement shall remain unchanged, such Lender shall remain
solely responsible for the performance thereof, such Lender shall remain the
holder of any such Loan for all purposes under this Agreement and the other Loan
Documents, and the Borrowers and the Agents shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and the other Loan Documents.  In no event
shall any Participant under any such participation have any right to approve any
amendment or waiver of any provision of any Loan Document, or any consent to any
departure by any Loan Party therefrom, except to the extent that such amendment,
waiver or consent would require the consent of all Lenders pursuant to Section
15.1. Each of Holdings and each Borrower agrees that if amounts outstanding
under this Agreement and the Loans are due or unpaid after applicable grace
periods, or shall have been declared or shall have become due and payable upon
the occurrence and during the continuation of an Event of Default, each
Participant shall, to the maximum extent permitted by applicable law, be deemed
to have the right of setoff in respect of its participating interest in amounts
owing under this Agreement to the same extent as if the amount of its
participating interest were owing directly to it as a Lender under this
Agreement, provided that, in purchasing such participating interest, such
           --------
Participant shall be deemed to have agreed to share with the Lenders the
proceeds thereof as provided in Section 5.7(a) as fully as if such Participant
were a Lender hereunder.  The Borrower also agrees that each Participant shall
be entitled to the benefits of Sections 7.11, 7.12 and 7.13 with respect to its
participation in the Commitments and the Loans outstanding from time to time as
if such Participant were a Lender if and to the extent the transferor Lender
waives its rights to such amounts; provided that, in the case of Section 7.13,
                                   --------
such Participant shall have complied with the requirements of said Section, and
provided, further, that no Participant shall be entitled to receive any greater
--------  -------
amount pursuant to any such Section 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.

          (c)  Any Lender (an "Assignor") may, in accordance with applicable law
                               --------
and upon written notice to the General Administrative Agent (and the Canadian
Administrative Agent, in the case of assignments with respect to the Canadian
Facilities), at any time and from time to time assign to any Lender or any
affiliate or Control Investment Affiliate thereof or, with the consent of the
relevant Borrower and the Administrative Agents and, in the case of any
assignment of U.S. Revolving Credit Commitments or Canadian Revolving Credit
Commitments, the written consent of each relevant Issuing Lender and Swing Line
Lender (which, in each case, shall not be unreasonably withheld or delayed)
(provided (x) that no such consent need be obtained by any Lehman Entity for a
 --------
period of 180 days following the Closing Date and (y) no consent of Borrowers
need be obtained with respect to any assignment of Term Loans), to an additional
bank, financial institution or other entity (an "Assignee") all or any part of
                                                 --------
its rights and obligations under this Agreement pursuant to an Assignment and
Acceptance, substantially in the form of Exhibit E, executed by such Assignee
and such Assignor (and, where the consent of a Borrower, the Administrative
Agents or any Issuing Lender or the Swing Line Lender is required pursuant to
the foregoing provisions, by such Borrower and such other Persons) and delivered
to the General Administrative Agent for its acceptance and recording in the
Register; provided that no such assignment to an Assignee (other than any Lender
          --------
or any affiliate thereof) shall be in an aggregate principal amount of less than
U.S.$5,000,000 (other than in the case of an assignment of all of a Lender's
interests under this Agreement), unless otherwise agreed by the relevant
Borrower and the General Administrative Agent.  Any such assignment need not be
ratable as among the Facilities.  Upon such execution, delivery, acceptance and
recording, from and after the effective date determined pursuant to such
Assignment and Acceptance, (x) the Assignee thereunder shall be a party hereto
and, to the extent provided in such Assignment and Acceptance, have the rights
and obligations of a Lender hereunder with  Commitments and/or Loans as set
forth therein, and (y) the Assignor thereunder shall, to the extent provided in
such Assignment and Acceptance, be released from its obligations under this
Agreement (and, in the case of an Assignment and Acceptance covering all of an
Assignor's rights and obligations under this Agreement, such Assignor shall
cease to be a party hereto, except as to Section 7.11, 7.13 and 15.5 in respect
of the period prior to such effective date).  Notwithstanding any provision of
this Section, the consent of the Borrowers shall not be required for any
assignment that occurs at any time when any Event of Default shall have occurred
and be continuing.  Any assignment of Canadian Facilities after the Syndication
Date must be to an Assignee that is entitled to receive payments in respect of
the Canadian Facilities free and clear of any withholding or similar tax imposed
by Canada or any province thereof.

          (d)  The General Administrative Agent (together with the Canadian
Administrative Agent, in the case of Canadian Facility Loans) shall, on behalf
of the relevant Borrower, maintain at its address referred to in Section 15.2 a
copy of each Assignment and Acceptance delivered to it and a register (the
"Register") for the recordation of the names and addresses of the Lenders and
 --------
the Commitments of, and principal amount of the Loans owing to, each Lender from
time to time.  The entries in the Register shall be conclusive, in the absence
of manifest error, and the Borrowers, each Agent and the Lenders shall treat
each Person whose name is recorded in the Register as the owner of the Loans and
any Notes evidencing such Loans recorded therein for all purposes of this
Agreement.  Any assignment of any Loan, whether or not evidenced by a Note,
shall be effective only upon appropriate entries with respect thereto being made
in the Register
<PAGE>

                                                                             133

(and each Note shall expressly so provide).  Any assignment or transfer of all
or part of a Loan evidenced by a Note shall be registered on the Register only
upon surrender for registration of assignment or transfer of the Note evidencing
such Loan, accompanied by a duly executed Assignment and Acceptance; thereupon
one or more new Notes in the same aggregate principal amount shall be issued to
the designated Assignee, and the old Notes shall be returned by the General
Administrative Agent to the relevant Borrower marked "canceled".  The Register
shall be available for inspection by the Borrowers or any Lender (with respect
to any entry relating to such Lender's Loans) at any reasonable time and from
time to time upon reasonable prior notice.

          (e)  Upon its receipt of an Assignment and Acceptance executed by an
Assignor and an Assignee (and, in any case where the consent of any other Person
is required by Section 15.6(c), by each such other Person) together with payment
to the General Administrative Agent of a registration and processing fee of
$3,500 (except that no such registration and processing fee shall be payable (y)
in connection with an assignment by or to any Lehman Entity or (z) in the case
of an Assignee which is already a Lender or is an affiliate or Control
Investment Affiliate of a Lender or a Person under common management with a
Lender), the General Administrative Agent shall (i) promptly accept such
Assignment and Acceptance and (ii) on the effective date determined pursuant
thereto record the information contained therein in the Register and give notice
of such acceptance and recordation to the Lenders, the Agents and the Borrowers.
On or prior to such effective date, the relevant Borrower, at its own expense,
upon request, shall execute and deliver to the General Administrative Agent (in
exchange for the Note or Notes of the assigning Lender) a new applicable Note
and/or applicable Notes to the order of such Assignee in an amount equal to the
Commitment and/or applicable Loans, as the case may be, assumed or acquired by
it pursuant to such Assignment and Acceptance and, if the Assignor has retained
a Commitment and/or Loans, as the case may be, upon request, a new Note or
Notes, as the case may be, to the order of the Assignor in an amount equal to
the Commitment and/or applicable Loans, as the case may be, retained by it
hereunder.  Such new Note or Notes shall be dated the Closing Date and shall
otherwise be in the form of the Note or Notes replaced thereby.

          (f)  For avoidance of doubt, the parties to this Agreement acknowledge
that the provisions of this Section concerning assignments of Loans and Notes
relate only to absolute assignments and that such provisions do not prohibit
assignments creating security interests, including, without limitation, any
pledge or assignment by a Lender of any Loan or Note to any Federal Reserve Bank
in accordance with applicable law.

          15.7  Adjustments; Set-off.  (a)  If any Lender (a "Benefitted
                --------------------                          ----------
Lender") (i) shall at any time prior to any date on which the Commitments are
------
terminated and the Loans, Reimbursement Obligations or Acceptance Reimbursement
Obligations become due and payable pursuant to Section 13 (an "Acceleration")
                                                               ------------
receive any payment of all or part of its Extensions of Credit made by it to any
Borrower, or interest thereon, or receive any collateral in respect thereof
(whether voluntarily or involuntarily, by set-off or otherwise), in a greater
proportion than any such payment to or collateral received by any other Lender,
if any, in respect of such other Lender's Extensions of Credit made by it to
such Borrower, or interest thereon (in each case except to the extent that this
Agreement provides for payments to be allocated to the Lenders under a
particular Facility) or (ii) (except as provided with respect to the Tranche C
Term Loans
<PAGE>

                                                                             134

in Section 15.18) shall at any time after an Acceleration receive any payment of
all or part of the aggregate amount of the Extensions of Credit made by such
benefitted Lender to all Borrowers, or interest thereon, or receive any
collateral in respect thereof (whether voluntarily, by set-off, pursuant to
events or proceedings of the nature referred to in Section 13(f), or otherwise),
in a greater proportion than any such payment or collateral received by any
other Lender, if any, in respect by the aggregate amount of the Extensions of
Credit made by such Lender to all Borrowers, or interest thereon, then, in each
case described in the foregoing clauses (i) and (ii), such Benefitted Lender
shall purchase for cash from the other Lenders a participating interest in such
portion of each such other Lender's Extensions of Credit, or shall provide such
other Lenders with the benefits of any such collateral, or the proceeds thereof,
as shall be necessary to cause such Benefitted Lender to share the excess
payment or benefits of such collateral or proceeds ratably with each of the
Lenders (to the extent required by the foregoing clause (i) or (ii), as
applicable); provided, however, that if all or any portion of such excess
             --------  -------
payment or benefits is thereafter recovered from such Benefitted Lender, such
purchase shall be rescinded, and the purchase price and benefits returned, to
the extent of such recovery, but without interest.

          (b) In addition to any rights and remedies of the Lenders provided by
law, each Lender shall have the right, without prior notice to the Borrowers,
any such notice being expressly waived by the Borrowers to the extent permitted
by applicable law, upon any amount becoming due and payable by a Borrower
hereunder (whether at the stated maturity, by acceleration or otherwise) after
any applicable grace period, to set-off and appropriate and apply against such
amount any and all deposits (general or special, time or demand, provisional or
final), in any currency, and any other credits, indebtedness or claims, in any
currency, in each case whether direct or indirect, absolute or contingent,
matured or unmatured, at any time held or owing by such Lender or any branch,
agency or Affiliate thereof to or for the credit or the account of the Borrower.
Each Lender agrees promptly to notify the Borrowers and the Administrative
Agents after any such set-off and application made by such Lender, provided that
                                                                   --------
the failure to give such notice shall not affect the validity of such set-off
and application.

          15.8  Counterparts. This Agreement may be executed by one or more of
                ------------
the parties to this Agreement on any number of separate counterparts, and all of
said counterparts taken together shall be deemed to constitute one and the same
instrument. Delivery of an executed signature page of this Agreement or of a
Lender Addendum by facsimile transmission shall be effective as delivery of a
manually executed counterpart hereof. A set of the copies of this Agreement and
Lender Addenda signed by all the parties shall be lodged with the Borrower and
the General Administrative Agent.

          15.9  Severability. Any provision of this Agreement that is
                ------------
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

          15.10 Integration. This Agreement and the other Loan Documents
                -----------
represent the entire agreement of Holdings, the Borrowers, the Agents, the
Arranger and the Lenders with

          (c)  agrees that service of process in any such action or proceeding
     may be effected by mailing a copy thereof by registered or certified mail

     extent necessary to permit consummation of such Disposition in accordance
     with the Loan Documents.

          (b)  Notwithstanding anything to the contrary contained herein or any
     other Loan Document, when all obligation of the Borrowers secured by the
     Security Documents (other than obligations in respect of any Specified
     Hedge Agreement) have been paid in full, all Commitments have terminated or
     expired and no Extensions of Credit shall be outstanding, upon request of
     the relevant Borrower, the relevant Administrative Agent

                                                                             137

     shall (without notice to, or vote or consent of, any Lender, or any
     affiliate of any Lender that is a party to any Specified Hedge Agreement)
     take such actions as shall be required to release its security interest in
     all Collateral, and to release all guarantee obligations under any Loan
     Document, whether or not on the date of such release there may be
     outstanding obligations in respect of Specified Hedge Agreements. Any such
     release of guarantee obligations shall be deemed subject to the provision
     that such guarantee obligations shall be reinstated if after such release
     any portion of any payment in respect of the obligations guaranteed thereby
     shall be rescinded or must otherwise be restored or returned upon the
     insolvency, bankruptcy, dissolution, liquidation or reorganization of any
     Borrower or any Guarantor, or upon or as a result of the appointment of a
     receiver, intervenor or conservator of, or trustee or similar officer for,
     any Borrower or any Guarantor or any substantial part of its property, or
     otherwise, all as though such payment had not been made.

          15.16  Accounting Changes. In the event that any "Accounting Change"
                 ------------------
(as defined below) shall occur and such change results in a change in the method
of calculation of financial covenants, standards or terms in this Agreement,
then Holdings and the Administrative Agent agree to enter into negotiations in
order to amend such provisions of this Agreement so as to equitably reflect such
Accounting Changes with the desired result that the criteria for evaluating
Holdings' financial condition shall be the same after such Accounting Changes as
if such Accounting Changes had not been made. Until such time as such an
amendment shall have been executed and delivered by the Borrowers, the
Administrative Agents and the Required Lenders, all financial covenants,
standards and terms in this Agreement shall continue to be calculated or
construed as if such Accounting Changes had not occurred. "Accounting Changes"
refers to changes in accounting principles required by the promulgation of any
rule, regulation, pronouncement or opinion by the Financial Accounting Standards
Board of the American Institute of Certified Public Accountants or, if
applicable, the SEC.

          15.17 Delivery of Lender Addenda. Each initial Lender shall become a

Lender Addendum duly executed by such Lender, the Borrowers and the General
Administrative Agent.

          15.18  Intercreditor Provisions. (a)  Notwithstanding (i) any
                 ------------------------
provision hereof or of any other Loan Document and (ii) the priority of any Lien
on the Collateral, all proceeds received by the Canadian Administrative Agent
from the Canadian Facility Guarantees or from the exercise by the Canadian
Administrative Agent of any of its remedies under any of the Canadian Security
Documents or the Canadian Facility Guarantees shall be  applied by the Canadian
Administrative Agent as follows:

          First, to reimburse the Canadian Administrative Agent for all costs
          -----
     and expenses incurred by them in administering the Collateral, the Canadian
     Facility Guarantees and the Canadian Security Documents and in enforcing
     rights thereunder;

          Second, to the Canadian Lenders to pay principal of, accrued and

     liabilities of the Canadian  Borrower under the Loan Documents (including,
     without limitation, the obligations of the Canadian Borrower to cash
     collateralize Canadian L/C Obligations and Acceptance Reimbursement
     Obligations), ratably among the Canadian Lenders according to the amounts
     of such indebtedness, liabilities and obligations owing to the Canadian

     Borrower or the other Loan Parties entitled thereto or as otherwise may be
     required under applicable law.

          (b) Notwithstanding (i) any provision hereof or of any other Loan
Document and (ii) the priority of any Lien on the Collateral, all proceeds
received by the General Administrative Agent from the guarantees contained in
the Guarantee and Collateral Agreement or from the exercise by the General
Administrative Agent of any of its remedies under any of the Security Documents
or the guarantees contained in the Guarantee and Collateral Agreement shall be
applied by the General Administrative Agent as follows:

          First, to reimburse the General Administrative Agent for all costs and
          -----
     expenses incurred by them in administering the Collateral and the Security
     Documents and in enforcing rights thereunder;

          Second, to the Lenders to pay principal of, accrued and unpaid
          ------
     interest on, and other amounts payable hereunder with respect to all
     indebtedness, obligations and liabilities of the U.S. Borrower under the
     Loan Documents (including, without limitation, the guarantee obligations of
     the U.S. Borrower pursuant to Section 12 and the obligations of the U.S.
     Borrower to cash collateralize U.S. L/C Obligations, but excluding any
     indebtedness, obligations and liabilities of any Loan Party  with respect
     to the Tranche C Term Loans) (all such non-excluded indebtedness,
     obligations and liabilities, collectively, the "First Priority
                                                     --------------
     Obligations"), ratably among the Lenders according to the amounts of First
     -----------
     Priority Obligations owing to the Lenders;

          Third, after payment in full of the First Priority Obligations, to the
          -----
     Tranche C Term Loan Lenders to pay the principal of, accrued and unpaid
     interest on, and other amounts payable hereunder with respect to, the
     Tranche C Term Loans; and

          Fourth, after payment in full of all of the amounts described in the
          ------
     foregoing clauses First, Second and Third of this paragraph (b), to the
     U.S. Borrower or the other Loan Parties entitled thereto or as otherwise
     may be required under applicable law.

          (c) The General Administrative Agent, and the Canadian Administrative
Agent under the direction of the General Administrative Agent, shall coordinate
their exercise of remedies and the application of the proceeds thereof with the
intent of causing the repayment of the largest possible amount of the
indebtedness, obligations and liabilities of the Canadian Borrower under the
Loan Documents before application toward such repayment of proceeds from (i) the
guarantee of the U.S. Borrower under Section 12, (ii) the guarantee contained in
the

Guarantee and Collateral Agreement or (iii) any Security Document (other than
the Canadian Security Documents).

          (d)  Notwithstanding any provision hereof or of any other Loan
Document, without the consent of a majority in outstanding principal amount of
the Tranche C Term Loan Lenders, neither Holdings nor any of its Subsidiaries
will create, incur, assume or suffer to exist any Indebtedness that ranks senior
or pari passu in right of payment or with respect to Collateral to the Tranche C
Term Loans (either directly or indirectly, including without limitation through
intercreditor arrangements or otherwise) other than Indebtedness which ranks
pari passu in right of payment or with respect to collateral with the First
Priority Obligations.
