            Communications, Inc., SBA Towers, Inc. and SBA Telecommunications,

Dear Tom:

        As contemplated in Section 3(a) of the Agreement, the Credit Agreement
has now been amended to permit additional Sites to be transferred to SBA.
Accordingly, I propose that with your acknowledgement, this letter serves to
amend the Agreement to increase the number of Sites up to and including Two
Hundred and Seventy-Five (275) completed Sites and increase the aggregate
purchase price to Ninety Million Sixty Two Thousand Five Hundred Dollars
($90,062,500.00).  All other terms and conditions of the Agreement shall remain
in full force and effect.

        If acceptable to you please return your executed acknowledgement to me
by facsimile at (703) 236-1376.

                                        Sincerely,

                                        /s/ Ronald W. Keefe, Jr.

Dear Ron:

        I am writing this letter to confirm our agreement today with respect to
that certain, Purchase Agreement ("Agreement") entered into by and among
TeleCorp Realty, LLC, TeleCorp Puerto Rico Realty, Inc., TeleCorp
Communications, Inc. (collectively "TeleCorp") and SBA Towers, Inc. ("SBA") on
September 15, 2000. SBA and TeleCorp hereby agree that a Closing shall occur on
March 16, 2001, at which time a minimum of two hundred (200) Sites shall be
approved for purchase by SBA and conveyed by TeleCorp to NewCo.

        Subsequent to such Closing and through July 19, 2001, SBA and TeleCorp
shall continue pursuant to Section 7(c) of the Agreement to take Curative
Actions with respect to any Sites subject to the Agreement but not yet closed
upon. One or more Closings upon such sites shall occur at such times or times as
may be agreed upon by the parties. In the event a March 16th 2001 Closing does
not occur as contemplated herein, TeleCorp hereby reserves its right under
Section 7(g) to terminate the Agreement as result of the rejection by SBA of
more than fifteen (15) of the two hundred seventy-five (275) sites which were
subject to the Agreement and to pursue any remedies available to it at law or
equity for breach of the Agreement as modified by this letter agreement.

        Except as set forth herein, all terms and conditions of the Agreement
shall remain in full force and effect. If you agree to the modifications to the
Agreement contained herein, please sign the acknowledgement set forth below and
return the signature page to me via facsimile at (703) 236-1376.

                                                Sincerely,

                                                /s/ Ronald W. Keefe

                                                Ronald W. Keefe, Jr.

          SECTION 2.04.  Swingline Loans.  (a)  Subject to the terms and
                         ----------------
conditions set forth herein, the Swingline Lender agrees to make Swingline Loans
to the U.S. Borrower from time to time during the U.S. $ Revolving Availability
Period, in an aggregate principal amount at any time outstanding that will not
result in (i) the aggregate principal amount of outstanding Swingline Loans
exceeding $25,000,000 or (ii) the sum of the aggregate U.S. $ Revolving
Exposures exceeding the Total U.S. $ Revolving Commitment; provided that the
                                                           --------
Swingline Lender shall not be required to make a Swingline Loan to refinance an
outstanding Swingline Loan.  Within the foregoing limits and subject to the
terms and conditions set forth herein, the U.S. Borrower may borrow, prepay and
reborrow Swingline Loans.

          (b)  To request a Swingline Loan, the U.S. Borrower shall notify the
U.S. Administrative Agent of such request by telephone (confirmed by telecopy),
not later than 2:00 p.m., New York City time, on the day of a proposed Swingline

date (which shall be a Business Day) and amount of the requested Swingline Loan.
The U.S. Administrative Agent will promptly advise the Swingline Lender of any
such notice received from the U.S. Borrower. The Swingline Lender shall make
each Swingline Loan available to the U.S. Borrower by means of a credit to the
general deposit account of the U.S. Borrower with the Swingline Lender (or, in
the case of a Swingline Loan made to finance the reimbursement of an LC
Disbursement as provided in Section 2.05(e), by remittance to the Issuing Bank)
by 3:00 p.m., New York City time, on the requested date of such Swingline Loan.

          (c)  The Swingline Lender may by written notice given to the U.S.

                                                                              52

outstanding. Such notice shall specify the aggregate amount of Swingline Loans
in which such U.S. $ Revolving Lenders will participate. Promptly upon receipt
of such notice, the U.S. Administrative Agent will give notice thereof to each
U.S. $ Revolving Lender, specifying in such notice such U.S. $ Revolving
Lender's Applicable Percentage of such Swingline Loan or Loans. Each U.S. $
Revolving Lender hereby absolutely and unconditionally agrees, upon receipt of
notice as provided above, to pay to the U.S. Administrative Agent, for the
account of the Swingline Lender, such U.S. $ Revolving Lender's Applicable
Percentage of such Swingline Loan or Loans. Each U.S. $ Revolving Lender
acknowledges and agrees that its obligation to acquire participations in
Swingline Loans pursuant to this paragraph is absolute and unconditional and
shall not be affected by any circumstance whatsoever, including the occurrence
and continuance of a Default or reduction or termination of the Commitments, and
that each such payment shall be made without any offset, abatement, withholding
or reduction whatsoever. Each U.S. $ Revolving Lender shall comply with its
obligation under this paragraph by wire transfer of immediately available funds,
in the same manner as provided in Section 2.06 with respect to Loans made by
such Lender (and Section 2.06 shall apply, mutatis mutandis, to the payment
                                           ------- --------
obligations of the U.S. $ Revolving Lenders), and the U.S. Administrative Agent
shall promptly pay to the Swingline Lender the amounts so received by it from
the U.S. $ Revolving Lenders. The U.S. Administrative Agent shall notify the
U.S. Borrower of any participations in any Swingline Loan acquired pursuant to
this paragraph, and thereafter payments in respect of such Swingline Loan shall
be made to the U.S. Administrative Agent and not to the Swingline Lender. Any
amounts received by the Swingline Lender from the U.S. Borrower (or other party
on behalf of the U.S. Borrower) in respect of a Swingline Loan after receipt by
the Swingline Lender of the proceeds of a sale of participations therein shall
be promptly remitted to the U.S. Administrative Agent; any such amounts received
by the U.S. Administrative Agent shall be promptly remitted by the U.S.
Administrative Agent to the U.S. $ Revolving Lenders that shall have made their
payments pursuant to this paragraph and to the Swingline Lender, as their
interests may appear. The purchase of participations in a Swingline Loan
pursuant to this paragraph shall not relieve the U.S. Borrower of any default in
the payment thereof.

          SECTION 2.05.  Letters of Credit.  (a)  General. Upon the Effective
                         ------------------       --------
Date, the Existing Letters of Credit will automatically, without any action on
the part of any Person, be deemed to be Letters of Credit issued hereunder for
the account of the U.S. Borrower for all purposes of this
<PAGE>

                                                                              53

Agreement and the other Loan Documents. In addition, subject to the terms and
conditions set forth herein, the U.S. Borrower may request the issuance of
Letters of Credit for its own account, in a form reasonably acceptable to the
U.S. Administrative Agent and the Issuing Bank, at any time and from time to
time during the U.S. $ Revolving Availability Period and prior to the date that
is five Business Days prior to the Revolving Maturity Date. In the event of any
inconsistency between the terms and conditions of this Agreement and the terms
and conditions of any form of letter of credit application or other agreement
submitted by the U.S. Borrower to, or entered into by the U.S. Borrower with,
the Issuing Bank relating to any Letter of Credit, the terms and conditions of
this Agreement shall control. All Letters of Credit shall be denominated in
Dollars.

          (b)  Notice of Issuance, Amendment, Renewal, Extension; Certain
               ----------------------------------------------------------
Conditions.  To request the issuance of a Letter of Credit (or the amendment,
-----------
renewal or extension of an outstanding Letter of Credit), the U.S. Borrower
shall hand deliver or telecopy (or transmit by electronic communication, if
arrangements for doing so have been approved by the Issuing Bank) to the Issuing
Bank and the U.S. Administrative Agent (reasonably in advance of the requested
date of issuance, amendment, renewal or extension) a notice requesting the
issuance of a Letter of Credit, or identifying the Letter of Credit to be
amended, renewed or extended, and specifying the date of issuance, amendment,
renewal or extension (which shall be a Business Day), the date on which such
Letter of Credit is to expire (which shall comply with paragraph (c) of this
Section), the amount of such Letter of Credit, the name and address of the
beneficiary thereof and such other information as shall be necessary to prepare,
amend, renew or extend such Letter of Credit.  If requested by the Issuing Bank,
the U.S. Borrower also shall submit a letter of credit application on the
Issuing Bank's standard form in connection with any request for a Letter of
Credit.  A Letter of Credit shall be issued, amended, renewed or extended only
if (and upon issuance, amendment, renewal or extension of each Letter of Credit
the U.S. Borrower shall be deemed to represent and warrant that), after giving
effect to such issuance, amendment, renewal or extension (i) the LC Exposure
shall not exceed $100,000,000 and (ii) the aggregate U.S. $ Revolving Exposures
shall not exceed the aggregate U.S. $ Revolving Commitments.

          (c)  Expiration Date.  Each Letter of Credit shall expire at or prior
               ----------------
to the close of business on the earlier of (i) the date one year after the date
of the issuance of
<PAGE>

                                                                              54

such Letter of Credit (or, in the case of any Existing Letter of Credit having a
later expiration date, such expiration date) or, in the case of any renewal or
extension thereof, one year after such renewal or extension, and (ii) the date
that is five Business Days prior to the Revolving Maturity Date.

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

          (e)  Reimbursement.  If the Issuing Bank shall make any LC
               --------------
Disbursement in respect of a Letter of Credit, the U.S. Borrower shall reimburse
such LC Disbursement by paying to the U.S. Administrative Agent an amount equal
to such LC Disbursement not later than 12:00 noon, New York City time, on the
date that such LC Disbursement is made, if the U.S. Borrower shall have received
notice of such LC Disbursement prior to 10:00 a.m., New York City time, on such
date, or, if such notice has not been received by the U.S. Borrower prior to
such time on such date, then not later than 12:00 noon, New York City time, on
(i) the Business Day that the U.S. Borrower receives such notice, if such notice
is received prior to 10:00 a.m., New York City time, on the day of receipt, or
(ii) the Business Day
<PAGE>

                                                                              55

immediately following the day that the U.S. Borrower receives such notice, if
such notice is not received prior to such time on the day of receipt; provided
                                                                      --------
that, if such LC Disbursement is not less than $1,000,000, the U.S. Borrower
may, subject to the conditions to borrowing set forth herein, request in
accordance with Section 2.03 or 2.04 that such payment be financed with an ABR
U.S. $ Revolving Borrowing or Swingline Loan in an equivalent amount and, to the
extent so financed, the U.S. Borrower's obligation to make such payment shall be
discharged and replaced by the resulting ABR U.S. $ Revolving Borrowing or
Swingline Loan. If the U.S. Borrower fails to make such payment when due, the
U.S. Administrative Agent shall notify each U.S. $ Revolving Lender of the
applicable LC Disbursement, the payment then due from the U.S. Borrower in
respect thereof and such U.S. $ Revolving Lender's Applicable Percentage
thereof. Promptly following receipt of such notice, each U.S. $ Revolving Lender
shall pay to the U.S. Administrative Agent its Applicable Percentage of the
payment then due from the U.S. Borrower, in the same manner as provided in
Section 2.06 with respect to Loans made by such U.S. $ Revolving Lender (and
Section 2.06 shall apply, mutatis mutandis, to the payment obligations of the
                          ------- --------
U.S. $ Revolving Lenders), and the U.S. Administrative Agent shall promptly pay
to the Issuing Bank the amounts so received by it from the U.S. $ Revolving
Lenders. Promptly following receipt by the U.S. Administrative Agent of any
payment from the U.S. Borrower pursuant to this paragraph, the U.S.
Administrative Agent shall distribute such payment to the Issuing Bank or, to
the extent that U.S. $ Revolving Lenders have made payments pursuant to this
paragraph to reimburse the Issuing Bank, then to such U.S. $ Lenders and the
Issuing Bank as their interests may appear. Any payment made by a U.S. $
Revolving Lender pursuant to this paragraph to reimburse the Issuing Bank for
any LC Disbursement (other than the funding of ABR U.S. $ Revolving Loans or a
Swingline Loan as contemplated above) shall not constitute a Loan and shall not
relieve the U.S. Borrower of its obligation to reimburse such LC Disbursement.

          (f)  Obligations Absolute.  The U.S. Borrower's obligation to
               --------------------
reimburse LC Disbursements as provided in paragraph (e) of this Section shall be
absolute, unconditional and irrevocable, and shall be performed strictly in
accordance with the terms of this Agreement under any and all circumstances
whatsoever and irrespective of (i) any lack of validity or enforceability of any
Letter of Credit or this Agreement, or any term or provision therein, (ii) any
draft or other document presented under a Letter of Credit proving to be forged,
fraudulent or invalid
<PAGE>

                                                                              56

in any respect or any statement therein being untrue or inaccurate in any
respect, (iii) payment by the Issuing Bank under a Letter of Credit against
presentation of a draft or other document that does not comply with the terms of
such Letter of Credit, or (iv) any other event or circumstance whatsoever,
whether or not similar to any of the foregoing, that might, but for the
provisions of this Section, constitute a legal or equitable discharge of, or
provide a right of setoff against, the U.S. Borrower's obligations hereunder.
Neither the U.S. Administrative Agent, the Lenders nor the Issuing Bank, nor any
of their Related Parties, shall have any liability or responsibility by reason
of or in connection with the issuance or transfer of any Letter of Credit or any
payment or failure to make any payment thereunder (irrespective of any of the
circumstances referred to in the preceding sentence), or any error, omission,
interruption, loss or delay in transmission or delivery of any draft, notice or
other communication under or relating to any Letter of Credit (including any
document required to make a drawing thereunder), any error in interpretation of
technical terms or any consequence arising from causes beyond the control of the
Issuing Bank; provided that the foregoing shall not be construed to excuse the
              --------
Issuing Bank from liability to the U.S. Borrower to the extent of any direct
damages (as opposed to consequential damages, claims in respect of which are
hereby waived by the U.S. Borrower to the extent permitted by applicable law)
suffered by the U.S. Borrower that are caused by the Issuing Bank's failure to
exercise care when determining whether drafts and other documents presented
under a Letter of Credit comply with the terms thereof.  The parties hereto
expressly agree that, in the absence of gross negligence or wilful misconduct on
the part of the Issuing Bank (as finally determined by a court of competent
jurisdiction), the Issuing Bank shall be deemed to have exercised care in each
such determination.  In furtherance of the foregoing and without limiting the
generality thereof, the parties agree that, with respect to documents presented
which appear on their face to be in substantial compliance with the terms of a
Letter of Credit, the Issuing Bank may, in its sole discretion, either accept
and make payment upon such documents without responsibility for further
investigation, regardless of any notice or information to the contrary, or
refuse to accept and make payment upon such documents if such documents are not
in strict compliance with the terms of such Letter of Credit.

          (g)  Disbursement Procedures.  The Issuing Bank shall, promptly
               -----------------------
following its receipt thereof, examine all documents purporting to represent a
demand for payment under a Letter of Credit.  The Issuing Bank shall promptly
notify
<PAGE>

                                                                              57

the U.S. Administrative Agent and the U.S. Borrower by telephone (confirmed by
telecopy) of such demand for payment and whether the Issuing Bank has made or
will make an LC Disbursement thereunder; provided that any failure to give or
                                         --------
delay in giving such notice shall not relieve the U.S. Borrower of its
obligation to reimburse the Issuing Bank and the U.S. $ Revolving Lenders with
respect to any such LC Disbursement.

          (h)  Interim Interest.  If the Issuing Bank shall make any LC
               ----------------
Disbursement, then, unless the U.S. Borrower shall reimburse such LC
Disbursement in full on the date such LC Disbursement is made, the unpaid amount
thereof shall bear interest, for each day from and including the date such LC
Disbursement is made to but excluding the date that the U.S. Borrower reimburses
such LC Disbursement, at the rate per annum then applicable to ABR U.S. $
Revolving Loans; provided that, if the U.S. Borrower fails to reimburse such LC
                 --------
Disbursement when due pursuant to paragraph (e) of this Section, then Section
2.13(e) shall apply.  Interest accrued pursuant to this paragraph shall be for
the account of the Issuing Bank, except that interest accrued on and after the
date of payment by any U.S. $ Revolving Lender pursuant to paragraph (e) of this
Section to reimburse the Issuing Bank shall be for the account of such U.S. $
Revolving Lender to the extent of such payment.

          (i)  Replacement of the Issuing Bank.  The Issuing Bank may be
               -------------------------------
replaced at any time by written agreement among the U.S. Borrower, the U.S.
Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank.
The U.S. Administrative Agent shall notify the U.S. $ Revolving Lenders of any
such replacement of the Issuing Bank.  At the time any such replacement shall
become effective, the U.S. Borrower shall pay all unpaid fees accrued for the
account of the replaced Issuing Bank pursuant to Section 2.12(b).  From and
after the effective date of any such replacement, (i) the successor Issuing Bank
shall have all the rights and obligations of the Issuing Bank under this
Agreement with respect to Letters of Credit to be issued thereafter and (ii)
references herein to the term "Issuing Bank" shall be deemed to refer to such
successor or to any previous Issuing Bank, or to such successor and all previous
Issuing Banks, as the context shall require.  After the replacement of an
Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto
and shall continue to have all the rights and obligations of an Issuing Bank
under this Agreement with respect to Letters of Credit issued by it prior to
such replacement, but shall not be required to issue additional Letters of
Credit.

          (j)  Cash Collateralization.  If any Event of Default shall occur and
               ----------------------
be continuing, on the Business Day that the U.S. Borrower receives notice from
the U.S. Administrative Agent or the Required Lenders (or, if the maturity of
the Loans has been accelerated, U.S. $ Revolving Lenders with LC Exposure
representing greater than 50% of the total LC Exposure) demanding the deposit of
cash collateral pursuant to this paragraph, the U.S. Borrower shall deposit in
an account with the U.S. Administrative Agent, in the name of the U.S.
Administrative Agent and for the benefit of the U.S. $ Revolving Lenders, an
amount in cash equal to the LC Exposure as of such date plus any accrued and
unpaid interest thereon; provided that the obligation to deposit such cash
                         --------
collateral shall become effective immediately, and such deposit shall become
immediately due and payable, without demand or other notice of any kind, upon
the occurrence of any Event of Default with respect to the U.S. Borrower
described in clause (i) or (j) of Article VII.  Each such deposit pursuant to
this paragraph or Section 2.11(b) shall be held by the U.S. Administrative Agent
as collateral for the payment and performance of the obligations of the U.S.
Borrower under this Agreement.  The U.S. Administrative Agent shall have
exclusive dominion and control, including the exclusive right of withdrawal,
over such account.  Other than any interest earned on the investment of such
deposits, which investments shall be made at the option and sole discretion of
the U.S. Administrative Agent and at the U.S. Borrower's risk and expense, such
deposits shall not bear interest. Interest or profits, if any, on such
investments shall accumulate in such account.  Moneys in such account shall be
applied by the U.S. Administrative Agent to reimburse the Issuing Bank for LC
Disbursements for which it has not been reimbursed and, to the extent not so
applied, shall be held for the satisfaction of the reimbursement obligations of
the U.S. Borrower for the LC Exposure at such time or, if the maturity of the
Loans has been accelerated (but subject to the consent of U.S. $ Revolving
Lenders with LC Exposure representing greater than 50% of the total LC

the U.S. Administrative Agent most recently designated by the U.S.
Administrative Agent for such purpose by notice to the Term Loan Lenders, the

U.S. Administrative Agent will make such Term Loans, U.S. $ Revolving Loans and
Additional Revolving Loans available to the U.S. Borrower by promptly crediting
the amounts so received, in like funds, to an account of the U.S. Borrower
maintained with the U.S. Administrative Agent in New York City and designated by
the U.S. Borrower in the applicable Borrowing Request; provided that ABR U.S. $

by it hereunder on the proposed date thereof by wire transfer of immediately
available funds by 12:00 noon, Toronto time, to the account of the Canadian
Administrative Agent most recently designated by the Canadian Administrative

promptly crediting the amounts so received, in like funds, to an account of the
Canadian Borrower designated in the applicable Borrowing Request (or, in the
case of a Loan made in the form of a B/A Borrowing, in accordance with Section

          (b)  Unless the applicable Administrative Agent shall have received
notice from a Lender prior to the proposed date of any Borrowing that such
Lender will not make available to such Administrative Agent such Lender's share
of such Borrowing, such Administrative Agent may assume that such Lender has
made such share available on such date in accordance with paragraph (a) of this
Section and may, in reliance upon such assumption, make available to the
applicable Borrower a corresponding amount in the required currency.  In such
event, if a Lender has not in fact made its share of the applicable Borrowing
available to such Administrative Agent, then the applicable Lender and the
applicable Borrower severally agree to pay to such Administrative Agent
forthwith on demand such

determined by the U.S. Administrative Agent in accordance with banking industry
rules on interbank compensation or (B) in the case of any such C $ Revolving
Lender, at a rate determined by the Canadian Administrative Agent to represent
its cost of overnight or short-term funds (which determination shall be
conclusive absent manifest error) or (ii) (A) in the case of the U.S. Borrower,
the interest rate applicable to ABR Loans of the applicable Class or (B) in the
case of the Canadian Borrower, the interest rate applicable to Canadian Prime
Rate Loans. If such Lender pays such amount to the applicable Administrative
Agent, then such amount shall constitute such Lender's Loan included in such
Borrowing.

          SECTION 2.07.  Interest Elections.  (a)  Each U.S. $ Revolving
                         ------------------
Borrowing, C $ Revolving Borrowing, Additional Revolving Borrowing and Term
Borrowing initially shall be of the Type specified in the applicable Borrowing
Request and, in the case of a Eurodollar Borrowing, shall have an initial
Interest Period as specified in such Borrowing Request and, in the case of a B/A
Borrowing, shall have a Contract Period and maturity date as specified in such
Borrowing Request.  Thereafter, the applicable Borrower may from time to time
elect to convert or continue the Type of, or the duration of the Interest Period
(or issue replacement B/As for a further Contract Period) applicable to, the
Loans included in any Borrowing, all as provided in this Section.  The
applicable Borrower may elect different options with respect to different
portions of the affected Borrowing, in which case each such portion shall be
allocated ratably among the Lenders holding the Loans comprising such Borrowing,
and the Loans comprising each such portion shall be considered a separate
Borrowing.  This Section shall not apply to Swingline Borrowings, which may not
be converted or continued.

          (b)  To make an election pursuant to this Section, the applicable
Borrower shall notify the applicable Administrative Agent of such election by
telephone by the time that a Borrowing Request would be required under Section
2.03 if such Borrower were requesting a U.S. $ Revolving Borrowing, C $
Revolving Borrowing or Additional Revolving Borrowing, as applicable, of the
Type resulting from such election to be made on the effective date of such
election.  Each such telephonic Interest

Election Request shall be irrevocable and shall be confirmed promptly by hand
delivery or telecopy to the applicable Administrative Agent of a written
Interest Election Request in a form approved by the applicable Administrative
Agent and signed by the applicable Borrower.

          (c)    Each telephonic and written Interest Election Request shall
specify the following information in compliance with Section 2.02 and paragraph
(f) of this Section:

          (i)    the Borrower making such Interest Election Request;

          (ii)   the Borrowing to which such Interest Election Request applies
     and, if different options are being elected with respect to different
     portions thereof, the portions thereof to be allocated to each resulting
     Borrowing (in which case the information to be specified pursuant to
     clauses (iv) and (v) below shall be specified for each resulting
     Borrowing);

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

          (iv)   whether the resulting Borrowing is to be an ABR Borrowing, a
     Eurodollar Borrowing, a Canadian Prime Rate Borrowing or a B/A Borrowing;

          (v)    if the resulting Borrowing is a Eurodollar Borrowing, the
     Interest Period to be applicable thereto after giving effect to such
     election, which shall be a period contemplated by the definition of the
     term "Interest Period"; and

          (vi)   if the resulting Borrowing is a B/A Borrowing, the Contract
     Period to be applicable thereto after giving effect to such election, which
     shall be a period contemplated by the definition of the term "Contract
     Period".

If any such Interest Election Request requests a Eurodollar Borrowing but does
not specify an Interest Period, then the U.S. Borrower shall be deemed to have
selected an Interest Period of one month's duration.  If any such Interest
Election Request requests a B/A Borrowing but does not specify a maturity date
or Contract Period, then the Canadian Borrower shall be deemed to have selected
a maturity date that is 30 days following the date of such B/A Borrowing.

                                                                              62

          (d)  Promptly following receipt of an Interest Election Request, the
applicable Administrative Agent shall advise each applicable Lender of the
details thereof and of such Lender's portion of each resulting Borrowing.

          (e)  If the U.S. Borrower fails to deliver a timely Interest Election
Request with respect to a Eurodollar Borrowing prior to the end of the Interest
Period applicable thereto, then, unless such Borrowing is repaid as provided
herein, at the end of such Interest Period such Borrowing shall be converted to
an ABR Borrowing.  If the Canadian Borrower fails to deliver a timely Interest
Election Request with respect to a B/A Borrowing prior to the maturity date
applicable thereto, then, unless such Borrowing is repaid as provided herein, at
the end of such Contract Period such Borrowing shall be converted to a Canadian
Prime Rate Borrowing.

          (f)  Notwithstanding any contrary provision hereof, if an Event of
Default has occurred and is continuing and the U.S. Administrative Agent, at the
request of the Required Lenders, so notifies the Borrowers, then, so long as an
Event of Default is continuing (i) no outstanding Borrowing may be converted to
or continued as a Eurodollar Borrowing or a B/A Borrowing, (ii) unless repaid,
each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of
the Interest Period applicable thereto and (iii) each outstanding B/A Borrowing
shall be converted or continued as a Canadian Prime Rate Loan on its maturity
date and any additional C $ Revolving Loans shall be made as Canadian Prime Rate
Loans.

          (g)  A Borrowing of any Class may not be converted to or continued as
a Eurodollar Borrowing if after giving effect thereto (i) the Interest Period
therefor would commence before and end after a date on which any principal of
the Loans of such Class is scheduled to be repaid and (ii) the sum of the
aggregate principal amount of outstanding Eurodollar Borrowings of such Class
with Interest Periods ending on or prior to such scheduled repayment date plus
the aggregate principal amount of outstanding ABR Borrowings of such Class would
be less than the aggregate principal amount of Loans of such Class required to
be repaid on such scheduled repayment date.

          (b)  The U.S. Borrower or the Canadian Borrower, as applicable, may at
any time terminate, or from time to time reduce, the Commitments of any Class;
provided that (i) each reduction of the Commitments of any Class shall be in an

that is less than the aggregate U.S. $ Revolving Exposure of the U.S. $
Revolving Lenders at the time, (iii) the Total C $ Revolving Commitment shall
not be reduced to an amount that is less than the aggregate C $ Revolving
Exposure of the C $ Revolving Lenders at the time and (iv) the Total Additional

aggregate principal amount of Additional Revolving Loans outstanding at such
time.

          (c)  The Revolving Commitments and Additional Revolving Commitments
shall be reduced as and to the extent required by Section 2.11(c).

to the effective date of such termination or reduction, specifying such election
and the effective date thereof.  Promptly following receipt of any such notice,
the applicable Administrative Agent shall advise the relevant Lenders of the
contents thereof.  Each notice delivered by either of the Borrowers pursuant to
this Section shall be irrevocable; provided that a notice of termination with

respect to any Revolving Commitment or Additional Revolving Commitment delivered
by the applicable Borrower may state that such notice is conditioned upon the
effectiveness of other credit facilities, in which case such notice may be
revoked by such Borrower (by notice to the applicable Administrative Agent on or
prior to the specified effective date) if such condition is not satisfied.  Any
termination or reduction of the Commitments of any Class pursuant to this
Section shall be permanent.  Each reduction of the Commitments of any Class
shall be made ratably among the Lenders in accordance with their respective
Commitments of such Class.

reasonably detailed calculation of the amount of such prepayment; provided that,
                                                                  --------

Administrative Agent shall advise the relevant Lenders of the contents thereof.
Each partial prepayment of any Borrowing shall be in an amount that would be
permitted in the case of an advance of a Borrowing of the same Type as provided
in Section 2.02, except as necessary to apply fully the required amount of a
mandatory prepayment.  Each prepayment of a Borrowing shall be applied ratably
to the Loans included in the prepaid Borrowing.  Prepayments shall be

Commitments pursuant to Section 2.23 shall become effective) to but excluding
the date on which such U.S. $ Revolving Commitment or Additional Revolving
Commitment terminates and (b) the Canadian Borrower agrees to pay to the
Canadian Administrative Agent for the account of each C $ Revolving Lender a
commitment fee (the "Canadian Commitment Fee" and, together with the U.S. $
                     -----------------------
Commitment Fee, the "Commitment Fees"), which shall accrue at the rate of 0.50%
                     ---------------
per annum on the average daily unused amount of the C $ Revolving Commitment of
such Lender during the period from and including the Effective Date to but
excluding the date on which such C $ Revolving Commitment terminates.  Accrued
Commitment Fees shall be payable in arrears on the last Business Day of March,
June, September and December of each year and on the date on which the U.S. $
Revolving

                                                                              69

Commitments, the C $ Revolving Commitments or Additional Revolving Commitments,
as applicable, terminate, commencing on the first such date to occur after the
date hereof. All Commitment Fees shall be computed on the basis of a year of 360
days and shall be payable for the actual number of days elapsed (including the
first day but excluding the last day). For purposes of computing the Commitment
Fees, (i) a U.S. $ Revolving Commitment of a U.S. $ Revolving Lender shall be
deemed to be used to the extent of the outstanding U.S. $ Revolving Loans and LC
Exposure of such Lender (and the Swingline Exposure of such Lender shall be
disregarded for such purpose), and (ii) a C $ Revolving Commitment of a C $
Revolving Lender shall be deemed to be used to the extent of the Dollar
Equivalent of the outstanding C $ Revolving Loans of such Lender (or, in the
case of outstanding C $ Revolving Loans that are in the form of B/As, the Dollar
Equivalent of the face amount of such B/As).

          (b)  The U.S. Borrower agrees to pay (i) to the U.S. Administrative
Agent for the account of each U.S. $ Revolving Lender a participation fee with
respect to its participations in Letters of Credit, which shall accrue at the
same Applicable Rate as interest on Eurodollar Revolving Loans on the average
daily amount of such Lender's LC Exposure (excluding any portion thereof
attributable to unreimbursed LC Disbursements) during the period from and
including the Effective Date to but excluding the later of the date on which
such Lender's U.S. $ Revolving Commitment terminates and the date on which such
Lender ceases to have any LC Exposure, and (ii) to the Issuing Bank a fronting
fee, which shall accrue at the rate of 0.250% per annum on the average daily
amount of the LC Exposure (excluding any portion thereof attributable to
unreimbursed LC Disbursements) during the period from and including the
Effective Date to but excluding the later of the date of termination of the U.S.
$ Revolving Commitments and the date on which there ceases to be any LC
Exposure, as well as the Issuing Bank's standard fees with respect to the
issuance, amendment, renewal or extension of any Letter of Credit or processing
of drawings thereunder.  Participation fees and fronting fees accrued through
and including the last day of March, June, September and December of each year
shall be payable in arrears on the third Business Day following such last day,
commencing on the first such date to occur after the Effective Date; provided
                                                                     --------
that all such fees shall be payable on the date on which the U.S. $ Revolving
Commitments terminate and any such fees accruing after the date on which the
U.S. $ Revolving Commitments terminate shall be payable on demand.  Any other
fees payable to the Issuing Bank pursuant to this paragraph shall be payable
<PAGE>

                                                                              70

within 10 days after demand. All participation fees and fronting fees shall be
computed on the basis of a year of 360 days and shall be payable for the actual
number of days elapsed (including the first day but excluding the last day).

          (c)  The U.S. Borrower agrees to pay to the U.S. Administrative Agent,
for its own account, fees payable in the amounts and at the times separately
agreed upon between Holdings and the U.S. Administrative Agent (and/or its
Affiliates).

          (d)  All fees payable hereunder shall be paid on the dates due, in
immediately available funds, to the applicable Administrative Agent (or to the
Issuing Bank, in the case of fees payable to it) for distribution, in the case
of commitment fees and participation fees, to the Lenders entitled thereto.  All
fees payable to the U.S. Administrative Agent, the Issuing Bank, the Swingline
Lender, the Term Lenders, the U.S. $ Revolving Lenders and the Additional
Revolving Lenders shall be payable in Dollars, and all fees payable to the
Canadian Administrative Agent and the C $ Revolving Lenders shall be payable in
Canadian Dollars.  Fees paid shall not be refundable under any circumstances.

          SECTION 2.13.  Interest.  (a)  The Loans comprising each ABR Borrowing
                         --------
(excluding each Swingline Loan) shall bear interest at the Alternate Base Rate
plus the Applicable Rate.  Each Swingline Loan shall bear interest at an annual
rate separately agreed upon by the U.S. Borrower and the Swingline Lender.

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

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

          (d)  Each B/A Borrowing shall be subject to an Acceptance Fee
calculated and payable at a rate per annum equal to the applicable B/A Spread
from time to time in effect and payable as set forth in Section 2.21.

          (e)  Notwithstanding the foregoing, if any principal of or interest on
any Loan or any fee or other amount payable by the Borrowers hereunder is not
paid when due, whether at stated maturity, upon acceleration or
<PAGE>

                                                                              71

otherwise, such overdue amount shall bear interest, after as well as before
judgment, at a rate per annum equal to (i) in the case of overdue principal of
any Loan, 2.00% plus the rate otherwise applicable to such Loan as provided in
the preceding paragraphs of this Section or (ii) in the case of any other
amount, 2.00% plus the rate applicable to ABR U.S. $ Revolving Loans as provided
in paragraph (a) of this Section.

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

          (g)  All interest hereunder shall be computed on the basis of a year
of 360 days, except that interest computed by reference to (i) the Alternate
Base Rate at times when the Alternate Base Rate is based on the Prime Rate and
(ii) the Canadian Prime Rate and the B/A Spread shall be computed on the basis
of a year of 365 days (or 366 days in a leap year), and in each case shall be
payable for the actual number of days elapsed (including the first day but
excluding the last day).  The applicable Alternate Base Rate or Canadian Prime
Rate for each day, or Adjusted IBO Rate for each Interest Period or Discount
Rate for each Contract Period, shall be determined by the U.S. Administrative
Agent or the Canadian Administrative Agent (in the case of Canadian Dollar
Borrowings), and such determination shall be conclusive absent manifest error.
The applicable Administrative Agent shall give the applicable Borrower prompt
notice of each such determination.

          (h)  For the purposes of the Interest Act (Canada) and disclosure
thereunder, whenever interest or a fee to be
<PAGE>

                                                                              72

paid hereunder or in connection herewith is to be calculated on the basis of a
year of 360 days or any other period of time that is less than a calendar year,
the yearly rate of interest or fee to which the rate determined pursuant to such
calculation is equivalent is the rate so determined (expressed as a percentage)
multiplied by the actual number of days in the calendar year in which the same
is to be ascertained and divided by either 360 or such other period of time, as
the case may be. The rates of interest under this Agreement are nominal rates,
and not effective rates or yields. The principle of deemed reinvestment of
interest does not apply to any interest calculation under this Agreement.

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

          (a) the U.S. Administrative Agent (in the case of a Term Loan, U.S. $
Revolving Loan or Additional Revolving Loan) or the Canadian Administrative
Agent (in the case of a C $ Revolving Loan) determines (which determination
shall be conclusive absent manifest error) that adequate and reasonable means do
not exist for ascertaining the Adjusted IBO Rate for such Interest Period or
Discount Rate for such Contract Period, as applicable; or

          (b) the applicable Administrate Agent is advised by a majority in
interest of the Lenders participating in such Borrowing that deposits in the
principal amounts of the Loans comprising such Borrowing and in the currency in
which such Loans are to be denominated are not generally available in the
international interbank market or there is not an adequate Canadian market for
bankers' acceptances, as applicable, or that the rates at which such deposits
are being offered or B/As are purchased will not adequately and fairly reflect
the cost to the Majority Lenders in respect of the affected Credit Facility of
making or maintaining its Eurodollar Loan during such Interest Period or its B/A
Borrowing or B/A Equivalent Note during such Contract Period, as applicable,
such Administrative Agent shall, as soon as practicable thereafter, give written
or telecopy notice of such determination to the applicable Borrower and the
applicable Lenders.  In the event of any such determination, until the
applicable Administrative Agent shall have advised the applicable Borrower and
the applicable Lenders that the circumstances giving rise to such notice no
longer exist, any request by the applicable Borrower for a Eurodollar Borrowing
or a B/A Borrowing, as applicable, pursuant to Section 2.03 or 2.07 shall be
deemed
<PAGE>

                                                                              73

to be a request for an ABR Borrowing (if a Eurodollar Borrowing has been
requested) or a Canadian Prime Rate Loan (if a B/A Borrowing has been
requested). Each determination by the Administrative Agents hereunder shall be
conclusive absent manifest error.

          In making any determination under this Section 2.14, the
Administrative Agents and each Lender will use good faith efforts to treat the
Borrowers in substantially the same manner as the Administrative Agent or such
Lender, as the case may be, treats other similarly situated borrowers under
similar circumstances.

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

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

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

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Eurodollar Loan or any C $ Revolving Loan
(or of maintaining its obligation to make any such Loan) or to increase the cost
to such Lender or the Issuing Bank of participating in, issuing or maintaining
any Letter of Credit or to reduce the amount of any sum received or receivable
by such Lender or the Issuing Bank hereunder (whether of principal, interest or
otherwise), then the U.S. Borrower will pay (or cause the Canadian Borrower to
pay in respect of the C $ Revolving Loans) to such Lender or the Issuing Bank,
as the case may be, such additional amount or amounts as will compensate such
Lender or the Issuing Bank, as the case may be, for such additional costs
incurred or reduction suffered.

          (b)  If any Lender or the Issuing Bank determines that any Change in
Law regarding capital requirements has or would have the effect of reducing the
rate of return on such Lender's or the Issuing Bank's capital or on the capital
of such Lender's or the Issuing Bank's holding company, if any, as a consequence
of this Agreement or the Loans made by, or
<PAGE>

                                                                              74

participations in Letters of Credit held by, such Lender, or the Letters of
Credit issued by the Issuing Bank, to a level below that which such Lender or
the Issuing Bank or such Lender's or the Issuing Bank's holding company could
have achieved but for such Change in Law (taking into consideration such
Lender's or the Issuing Bank's policies and the policies of such Lender's or the
Issuing Bank's holding company with respect to capital adequacy), then from time
to time the U.S. Borrower will pay (or cause the Canadian Borrower to pay in
respect of the C $ Revolving Loans) to such Lender or the Issuing Bank, as the
case may be, such additional amount or amounts as will compensate such Lender or
the Issuing Bank or such Lender's or the Issuing Bank's holding company for any
such reduction suffered.

          (c)  A certificate of a Lender or the Issuing Bank setting forth (and
showing in reasonable detail the calculation of) the amount or amounts necessary
to compensate such Lender or the Issuing Bank or its holding company, as the
case may be, as specified in paragraph (a) or (b) of this Section shall be
delivered to the U.S. Borrower and shall be conclusive absent manifest error.
The U.S. Borrower shall pay (or cause the Canadian Borrower to pay in respect of
the C $ Revolving Loans) such Lender or the Issuing Bank, as the case may be,
the amount shown as due on any such certificate within 10 days after receipt
thereof.

          (d)  Failure or delay on the part of any Lender or the Issuing Bank to
demand compensation pursuant to this Section shall not constitute a waiver of
such Lender's or the Issuing Bank's right to demand such compensation; provided
                                                                       --------
that neither the U.S. Borrower nor the Canadian Borrower shall be required to
compensate a Lender or the Issuing Bank pursuant to this Section for any
increased costs or reductions incurred more than 270 days prior to the date that
such Lender or the Issuing Bank, as the case may be, notifies the U.S. Borrower
of the Change in Law giving rise to such increased costs or reductions and of
such Lender's or the Issuing Bank's intention to claim compensation therefor;
provided, further, that if the Change in Law giving rise to such increased costs
--------  -------
or reductions is retroactive, then the 270-day period referred to above shall be
extended to include the period of retroactive effect thereof.

          (e) In requesting any compensation pursuant to this Section, each
Lender and the Issuing Bank will use good faith efforts to treat the Borrowers
in substantially the same manner as such Lender or the Issuing Bank, as the case
<PAGE>

                                                                              75

may be, treats other similarly situated borrowers under similar circumstances.

          SECTION 2.16.  Break Funding Payments.  In the event of (a) the
                         ----------------------
payment of any principal of any Eurodollar Loan or Bankers' Acceptance other
than on the last day of an Interest Period or Contract Period applicable thereto
(including as a result of an Event of Default), (b) the conversion of, or the
exchange pursuant to Article X of, any Eurodollar Loan or Bankers' Acceptance
other than on the last day of the Interest Period or Contract Period applicable
thereto, (c) the failure to borrow, convert, continue or prepay any Revolving
Loan or Term Loan on the date specified in any notice delivered pursuant hereto
(regardless of whether such notice may be revoked under Section 2.11(e) and is
revoked in accordance therewith) or (d) the assignment of any Eurodollar Loan or
Bankers' Acceptance other than on the last day of the Interest Period or
Contract Period applicable thereto as a result of a request by the applicable
Borrower pursuant to Section 2.19, then, in any such event, the applicable
Borrower shall compensate each Lender for the loss, cost and expense
attributable to such event.  In the case of a Eurodollar Loan or Bankers'
Acceptance, such loss, cost or expense to any Lender shall be deemed to include
an amount determined by such Lender to be the excess, if any, of (i) the amount
of interest that would have accrued on the principal amount of such Loan had
such event not occurred, at the Adjusted IBO Rate or the Discount Rate that
would have been applicable to such Loan, for the period from the date of such
event to the last day of the then current Interest Period or Contract Period
therefor (or, in the case of a failure to borrow, convert or continue, for the
period that would have been the Interest Period or Contract Period for such
Loan), over (ii) the amount of interest that would accrue on such principal
amount for such period at the interest rate that such Lender would bid were it
to bid at the commencement of such period, for deposits or bankers' acceptances
of a comparable amount and period and in the same currency from other banks in
the eurodollar market or the Canadian market, as applicable.  A certificate of
any Lender setting forth any amount or amounts that such Lender is entitled to
receive pursuant to this Section shall be delivered to the applicable Borrower
and shall be conclusive absent manifest error.  The applicable Borrower shall
pay such Lender the amount shown as due on any such certificate within 10 days
after receipt thereof.  Nothing in this Section 2.16 shall be construed to
permit a voluntary prepayment of a B/A Borrowing other than on the last day of a
Contract Period.

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

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

          (c)  The applicable Borrower shall indemnify each Agent, each Lender
and the Issuing Bank, within 10 days after written demand therefor, for the full
amount of any Indemnified Taxes or Other Taxes paid by such Agent, such Lender
or the Issuing Bank, as the case may be, on or with respect to any payment by or
on account of any obligation of the applicable Borrower hereunder or under any
other Loan Document (including Indemnified Taxes or Other Taxes imposed or
asserted on or attributable to amounts payable under this Section) and any
penalties, interest and reasonable expenses arising therefrom or with respect
thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or
legally imposed or asserted by the relevant Governmental Authority.  A
certificate as to the amount of such payment or liability delivered to the
applicable Borrower by a Lender or the Issuing Bank, or by the applicable
Administrative Agent on its own behalf or on behalf of a Lender or the Issuing
Bank, shall be conclusive absent manifest error.

          (d)  As soon as practicable after any payment of Indemnified Taxes or
Other Taxes by either Borrower to a Governmental Authority, such Borrower shall
deliver to the U.S. Administrative Agent the original or a certified copy of a
receipt issued by such Governmental Authority evidencing such payment, a copy of
the return reporting such payment or other evidence of such payment reasonably
satisfactory to the U.S. Administrative Agent.

          (e)  Any Foreign Lender (or Participant that would be a Foreign Lender
if it were a Lender) or any other recipient of any payment to be made by or on
account of any obligation of either Borrower hereunder or under any other Loan
Document that is entitled to an exemption from or reduction of withholding tax
under the law of the jurisdiction in which a Borrower is located, or any treaty
to which such jurisdiction is a party, with respect to payments by or on account
of any obligation of the applicable Borrower hereunder or under any other Loan
Document shall deliver to the applicable Borrower (with a copy to the applicable
Administrative Agent), at the time or times prescribed by applicable law,
Internal Revenue Service Form W-8BEN or W-8ECI, as applicable (or any successor
form), or such properly completed and executed documentation prescribed by
applicable law or reasonably requested by applicable Borrower as will permit
such payments to be made without withholding or at a reduced rate.

          (f)  If any Lender, Participant, the Issuing Bank or any Agent or any
other recipient of any payment to be made by or on account of any obligation of
the U.S. Borrower or the Canadian Borrower hereunder or under any other Loan
Document shall become aware that it is entitled to receive a refund, reduction
or credit in respect of amounts paid by the U.S. Borrower or the Canadian
Borrower pursuant to this Section 2.17, which refund, reduction or credit in the
good faith judgment of such Lender, Participant, Issuing Bank or any Agent or
any other recipient of any payment to be made by or on account of any obligation
of the U.S. Borrower or the Canadian Borrower hereunder or under any other Loan
Document is allocable to such payment, it shall promptly notify such Borrower of
the availability of such refund, reduction or credit and shall, within 30 days
after the receipt of a request by such Borrower, apply for such refund,
reduction or credit.  If any Lender, Participant, the Issuing Bank or any Agent
or any other recipient of any payment to be made by or on account of any
obligation of the U.S. Borrower or the Canadian Borrower hereunder or under any
other Loan Document receives a refund, reduction or credit in respect of any
amounts paid by either Borrower pursuant to this Section 2.17, which refund,

hereunder or under any other Loan Document is allocable to such payment, it
shall promptly notify such Borrower of such refund, reduction or credit and
shall, within 15 days after receipt, repay such refund or the amount of such
reduction or credit to such Borrower net of all out-of-pocket expenses

of such Lender, Participant, Issuing Bank or any Agent or any other recipient of
any payment to be made by or on account of any obligation of the U.S. Borrower
hereunder or the Canadian Borrower hereunder or under any other Loan Document;
provided, however, that such Borrower, upon the request of such Lender,

Agent or any other recipient of any payment to be made by or on account of any
obligation of the U.S. Borrower or the Canadian Borrower or under any other Loan
Document in the event such Lender, Participant, Issuing Bank or any Agent or any
other recipient of any payment to be made by or on account of any obligation of
the U.S. Borrower or the Canadian Borrower hereunder or under any other Loan
Document is required to repay such refund, reduction or credit, which repayment
shall in no event be made fewer than five days prior to the date on which such

under such other Loan Document for such payment (or, if no such time is
expressly required, prior to 2:00 p.m., New York City time), on the date when
due, in immediately available funds, without setoff or counterclaim.  Any
amounts received after such time on any date may, in the discretion of the U.S.

deemed to have been received on the next succeeding Business Day for purposes of
calculating interest thereon.  All payments to the U.S. Administrative Agent

except payments to be made directly to the Issuing Bank or Swingline Lender as
expressly provided herein and payments pursuant to Sections 2.15, 2.16, 2.17 and
9.03 shall be made directly to the Persons entitled thereto and payments
pursuant to other Loan Documents shall be made to the Persons specified therein.
All payments to the Canadian Administrative Agent shall be made to it at c/o
Royal Bank of Canada, Correspondent Banking Division, Financial Institution
Account Services, 180 Wellington Street, 6th Floor, Toronto, Ontario M5J2J5
except that payments pursuant to Sections 2.15, 2.16, 2.17 and 9.03 shall be
made directly to the Persons entitled thereto and payments pursuant to other
Loan Documents shall be made to the Persons specified therein.  The applicable
Administrative Agent shall distribute any such payments received by it for the
account of any other Person to the appropriate recipient promptly following
receipt thereof.  If any payment under any Loan Document shall be due on a day
that is not a Business Day, the date for payment shall be extended to the next
succeeding Business Day, and, in the case of any payment accruing interest,
interest thereon shall be payable for the period of such extension.

          (b)  If at any time insufficient funds are received by and available
to (i) the U.S. Administrative Agent to pay fully all amounts of principal,
unreimbursed LC Disbursements, interest and fees then due with respect to the
U.S. $ Revolving Commitments and the U.S. $ Revolving Loans hereunder, such
funds shall be applied (A) first, towards payment of interest and fees then due
hereunder with respect thereto, ratably among the parties entitled thereto in
accordance with the amounts of interest and fees then due to such parties, and
(B) second, towards payment of principal and unreimbursed LC Disbursements then
due hereunder, ratably among the parties entitled thereto in accordance with the
amounts of principal and unreimbursed LC Disbursements then due to such parties,
(ii) the Canadian Administrative Agent to pay fully all amounts of principal,
interest and fees then due with respect to the C $ Revolving Commitments and the
C $ Revolving Loans hereunder, such funds shall be applied (A) first, towards
payment of interest and fees then due hereunder with respect thereto, ratably
among the parties entitled thereto in accordance with the amounts of interest
and fees then due to such parties, and (B) second, towards payment of principal
then due with respect to the C $ Revolving Commitments and C $ Revolving Loans
hereunder, ratably among the parties entitled thereto in accordance with the
amounts of principal then due to such parties and (iii) the U.S. Administrative
Agent to pay fully all amounts of principal, interest and fees then due with
respect to the Additional Revolving Commitments and Additional Revolving Loans
hereunder, such funds shall be applied (A) first, towards payment of interest
and fees then due hereunder with respect thereto, ratably among the parties
entitled thereto in accordance with the amounts of interest and fees then due to
such parties and (B) second, towards payment of principal then

                                                                              80

due hereunder, ratably among the parties entitled thereto in accordance with the
amounts of principal then due to such parties.

          (c)  If any Lender shall, by exercising any right of setoff or
counterclaim or otherwise, obtain payment in respect of any principal of or
interest on any of its U.S. $ Revolving Loans, C $ Revolving Loans, Additional
Revolving Loans, Term Loans or participations in LC Disbursements or Swingline
Loans resulting in such Lender receiving payment of a greater proportion of the
aggregate amount of its U.S. $ Revolving Loans, C $ Revolving Loans, Additional
Revolving Loans, Term Loans, participations in LC Disbursements and
participations in Swingline Loans and accrued interest thereon than the
proportion received by any other Lender, then the Lender receiving such greater
proportion shall purchase (for cash at face value) participations in the
Revolving Loans, C $ Revolving Loans, Additional Revolving Loans, Term Loans,
participations in LC Disbursements and participations in Swingline Loans of
other Lenders to the extent necessary so that the benefit of all such payments
shall be shared by the Lenders ratably in accordance with the aggregate amount
of principal of and accrued interest on their respective U.S. $ Revolving Loans,
C $ Revolving Loans, Additional Revolving Loans, Term Loans, participations in
LC Disbursements and participations in Swingline Loans; provided that (i) if any
                                                        --------
such participations are purchased and all or any portion of the payment giving
rise thereto is recovered, such participations shall be rescinded and the
purchase price restored to the extent of such recovery, without interest, and
(ii) the provisions of this paragraph shall not be construed to apply to any
payment made by either Borrower pursuant to and in accordance with the express
terms of this Agreement or any payment obtained by a Lender as consideration for
the assignment of or sale of a participation in any of its Loans or
participations in LC Disbursements to any assignee or participant, other than to
the Borrowers or any Subsidiary or Affiliate thereof (as to which the provisions
of this paragraph shall apply). Each Borrower consents to the foregoing and
agrees, to the extent it may effectively do so under applicable law, that any
Lender acquiring a participation pursuant to the foregoing arrangements may
exercise against such Borrower rights of setoff and counterclaim with respect to
such participation as fully as if such Lender were a direct creditor of such
Borrower in the amount of such participation.

          (d)  Unless the applicable Administrative Agent shall have received
notice from the applicable Borrower
<PAGE>

                                                                              81

prior to the date on which any payment is due to such Administrative Agent for
the account of the Lenders or the Issuing Bank hereunder that the applicable
Borrower will not make such payment, the applicable Administrative Agent may
assume that such Borrower has made such payment on such date in accordance
herewith and may, in reliance upon such assumption, distribute to the relevant
Lenders or the Issuing Bank, as applicable, the amount due. In such event, if
the applicable Borrower has not in fact made such payment, then each of the
Lenders or the Issuing Bank, as applicable, severally agrees to repay to the
applicable Administrative Agent forthwith on demand the amount so distributed to
such Lender or the Issuing Bank with interest thereon, for each day from and
including the date such amount is distributed to it to but excluding the date of
payment to the applicable Administrative Agent, (i) in the case of payments to
the U.S. Administrative Agent, at the greater of the Federal Funds Effective
Rate and a rate determined by the U.S. Administrative Agent in accordance with
banking industry rules on interbank compensation and (ii) in the case of
payments to the Canadian Administrative Agent, the greater of a rate determined
by the Canadian Administrative Agent to represent its cost of overnight or
short-term funds and a rate in accordance with applicable banking industry rules
on interbank compensation.

          (e)  If any Lender shall fail to make any payment required to be made
by it pursuant to Section 2.04(c), 2.05(d) or (e), 2.06(b), 2.18(d) or 9.03(c),
then the applicable Administrative Agent may, in its discretion (notwithstanding
any contrary provision hereof), apply any amounts thereafter received by such
Administrative Agent for the account of such Lender to satisfy such Lender's
obligations under such Sections until all such unsatisfied obligations are fully
paid.

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

                                                                              82

hereby agrees to pay all reasonable costs and expenses incurred by any Lender in
connection with any such designation or assignment.

          (b)  If (i) any Lender requests compensation under Section 2.15, (ii)
either Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.17 or
(iii) any Lender defaults in its obligation to fund Loans hereunder, then the
applicable Borrower may, at its sole expense and effort, upon notice to such
Lender and the applicable Administrative Agent, require such Lender to assign
and delegate, without recourse (in accordance with and subject to the
restrictions contained in Section 9.04), all its interests, rights and
obligations under this Agreement to an assignee that shall assume such
obligations (which assignee may be another Lender, if a Lender accepts such
assignment); provided that (A) the applicable Borrower shall have received the
             --------
prior written consent of the applicable Administrative Agent (and, if a U.S. $
Revolving Commitment is being assigned, the Issuing Bank and Swingline Lender),
which consent, in each case, shall not unreasonably be withheld, (B) such Lender
shall have received payment of an amount equal to the outstanding principal of
its Loans and participations in LC Disbursements and Swingline Loans, accrued
interest thereon, accrued fees and all other amounts payable to it hereunder,
from the assignee (to the extent of such outstanding principal and accrued
interest and fees) or the applicable Borrower (in the case of all other
amounts), and (C) in the case of any such assignment resulting from a claim for
compensation under Section 2.15 or payments required to be made pursuant to
Section 2.17, such assignment will result in a material reduction in such
compensation or payments.  A Lender shall not be required to make any such
assignment and delegation if, prior thereto, as a result of a waiver by such
Lender or otherwise, the circumstances entitling the applicable Borrower to
require such assignment and delegation cease to apply.

          SECTION 2.20.  Incremental Facility.  At any time prior to the sixth
                         ---------------------
anniversary of the Effective Date, the U.S. Borrower may, by notice to the U.S.
Administrative Agent (which shall promptly deliver a copy to each of the
Lenders), request the addition of a new tranche of term loans (the "Incremental
                                                                    -----------
Term Loans"); provided that both at the time of any such request and upon the
----------    --------
effectiveness of the Incremental Facility Amendment referred to below, no
Default shall exist and at the time that any such Incremental Term Loans are
made (and after giving effect thereto) no Default shall exist and Holdings and
the Borrowers shall be in compliance with Section 6.01,

determined on a pro forma basis as if such Incremental Term Loans had been
incurred at the beginning of the most recent period for testing compliance
therewith. The Incremental Term Loans (i) shall be in an aggregate principal
amount not exceeding (in the aggregate) $250,000,000, (ii) shall rank pari passu
                                                                      ---- -----
in right of payment and of security with the Revolving Loans and the Term Loans,
(iii) shall not mature earlier than the Term Loan Maturity Date (but may,
subject to clause (iv) below, have amortization and commitment reductions prior
to such date), (iv) shall not have a weighted average life that is shorter than
that of the Term Loans, (v) shall not accrue interest at a rate or rates in
excess of the interest rates applicable to the Term Loans and (vi) shall
otherwise be treated no more favorably than the Term Loans (in each case,
including with respect to mandatory and voluntary prepayments); provided that
                                                                --------
the terms and conditions applicable to the Incremental Term Loans may provide
for additional or different financial or other covenants applicable only during
periods after the Term Loan Maturity Date. Such notice shall set forth the
requested amount of Incremental Term Loans. In the event that existing Lenders
provide commitments in an aggregate amount less than the total amount of the
Incremental Term Loans requested by the U.S. Borrower (but the U.S. Borrower
shall not have any obligation to request any Lender to provide any amount of the
Incremental Term Loans), the U.S. Borrower may arrange for one or more banks or
other financial institutions (any such bank or other financial institution being
called an "Additional Lender") to extend commitments to provide Incremental Term
           -----------------
Loans in an aggregate amount equal to the unsubscribed amount. Commitments in
respect of Incremental Term Loans shall become Commitments under this Agreement
pursuant to an amendment (an "Incremental Facility Amendment") to this Agreement
                              ------------------------------
and, as appropriate, the other Loan Documents, executed by Holdings, the U.S.
Borrower, each Lender agreeing to provide such Commitment, if any, each
Additional Lender, if any, and the U.S. Administrative Agent. The Incremental
Facility Amendment may, without the consent of any other Lenders, effect such
amendments to this Agreement and the other Loan Documents as may be necessary or
appropriate, in the opinion of the U.S. Administrative Agent, to effect the
provisions of this Section. The effectiveness of any Incremental Facility
Amendment shall be subject to the satisfaction on the date thereof of each of
the conditions set forth in Section 4.02 (it being understood that all
references to "the date of such Borrowing" in such Section 4.02 shall be deemed
to refer to the effective date of such Incremental Facility Amendment). No
Lender shall be obligated to provide any Incremental Term Loans unless it so
agrees.

          SECTION 2.21.  Bankers' Acceptances.  (a)  Subject to the terms and
                         ---------------------
conditions of this Agreement, the Canadian Borrower may request a C $ Revolving
Borrowing by presenting drafts for acceptance and purchase as B/As by the C $
Revolving Lenders.

          (b)  To facilitate B/A Borrowings, the Canadian Borrower hereby
appoints each C $ Revolving Lender as its attorney to sign and endorse on its
behalf, in handwriting or by facsimile or mechanical signature as and when
deemed necessary by such Lender, blank forms of B/As in the form requested by
such Lender.  In this respect, it is each C $ Revolving Lender's responsibility
to maintain an adequate supply of blank forms of B/As for acceptance under this
Agreement.  The Canadian Borrower recognizes and agrees that all B/As signed
and/or endorsed on its behalf by a C $ Revolving Lender shall bind the Canadian
Borrower as fully and effectually as if signed in the handwriting of and duly
issued by the proper signing officers of the Canadian Borrower.  Each C $
Revolving Lender is hereby authorized to issue such B/As endorsed in blank in
such face amounts as may be determined by such Lender; provided that the
                                                       --------
aggregate amount thereof is equal to the aggregate amount of B/As required to be
accepted and purchased by such Lender. No C $ Revolving Lender shall be liable
for any damage, loss or other claim arising by reason of any loss or improper
use of any such instrument except the gross negligence or wilful misconduct of
such Lender or its officers, employees, agents or representatives.  Each C $
Revolving Lender shall maintain a record with respect to B/As (i) received by it
in blank hereunder, (ii) voided by it for any reason, (iii) accepted and
purchased by it hereunder and (iv) canceled at their respective maturities.
Each C $ Revolving Lender further agrees to retain such records in the manner
and for the statutory periods provided in the various provincial or federal
statutes and regulations that apply to such Lender.  Each C $ Revolving Lender
agrees to provide a copy of such records to the Canadian Borrower at the
Canadian Borrower's expense upon request.  On request by or on behalf of the
Canadian Borrower, a C $ Revolving Lender shall cancel all forms of B/A that
have been pre-signed or pre-endorsed on behalf of the Canadian Borrower and that
are held by such Lender and are not required to be issued in accordance with the
Canadian Borrower's irrevocable notice.

          (c)  Drafts of the Canadian Borrower to be accepted as B/As hereunder
shall be signed as set forth in this Section 2.21.  Notwithstanding that any
person whose signature appears on any B/A may no longer be an authorized
signatory for any C $ Revolving Lender or the Canadian
<PAGE>

                                                                              85

Borrower at the date of issuance of a B/A, such signature shall nevertheless be
valid and sufficient for all purposes as if such authority had remained in force
at the time of such issuance and any such B/A so signed shall be binding on the
Canadian Borrower.

          (d)  Promptly following receipt of a Borrowing Request or notice of
rollover pursuant to Section 2.03 by way of B/As, the Canadian Administrative
Agent shall so advise the C $ Revolving Lenders and shall advise each C $
Revolving Lender of the aggregate face amount of the B/As to be accepted by it
and the applicable Contract Period (which shall be identical for all C $
Revolving Lenders).  The aggregate face amount of the B/As to be accepted by a C
$ Revolving Lender shall be a whole multiple of C $100,000, and such face amount
shall be in the C $ Revolving Lenders' pro rata portions of such C $ Revolving
Borrowing; provided that the Canadian Administrative Agent may in its sole
           --------
discretion increase or reduce any C $ Revolving Lender's portion of such B/A
Borrowing to the nearest C $100,000.

          (e)  Upon acceptance of a B/A by a C $ Revolving Lender, such Lender
shall purchase, or arrange the purchase of, each B/A from the Canadian Borrower
at the Discount Rate for such Lender applicable to such B/A accepted by it and
provide to the Canadian Administrative Agent the Discount Proceeds for the
account of the Canadian Borrower.  The Canadian Borrower will, upon acceptance
of a B/A by a C $ Revolving Lender, be obligated to pay to the Canadian
Administrative Agent on behalf of the C $ Revolving Lender that accepted the B/A
an Acceptance Fee in respect of such B/A.  The Acceptance Fee payable by the
Canadian Borrower to a C $ Revolving Lender under this Section 2.21(e) in
respect of each B/A accepted by such Lender shall be set off against the
Discount Proceeds payable by such Lender under this Section 2.21(e).

          (f)  Each C $ Revolving Lender may at any time and from time to time
hold, sell, rediscount or otherwise dispose of any or all B/As accepted and
purchased by it.

          (g)  If a C $ Revolving Lender notifies the Canadian Administrative
Agent in writing that it is unable or unwilling to accept Bankers' Acceptances,
such Lender will, instead of accepting and purchasing Bankers' Acceptances,
purchase from the Canadian Borrower a note that does not bear interest during
the Contract Period (a "B/A Equivalent Note"), in the form of Exhibit K, issued
                        -------------------
by the Canadian Borrower in the amount and for the same term as the draft that
such Lender would otherwise have been required to accept and purchase hereunder,
at a purchase price
<PAGE>

                                                                              86

calculated on the same basis as Bankers' Acceptances are discounted pursuant to
this Agreement. Each such Lender will provide to the Canadian Administrative
Agent the proceeds of such purchase for the account of the Canadian Borrower.
The Canadian Borrower will, upon purchase of a B/A Equivalent Note, pay to the
Canadian Administrative Agent on behalf of the C $ Revolving Lender that
purchased from the Canadian Borrower the B/A Equivalent Note an Acceptance Fee
in respect of such B/A Equivalent Note. The Acceptance Fee payable by the
Canadian Borrower to a C $ Revolving Lender under this Section 2.21(g) in
respect of each B/A Equivalent Note purchased by such Lender shall be set off
against the Discount Proceeds payable by such Lender under this Section 2.21(g).

          (h)  With respect to each B/A Borrowing, at or before 10:00 a.m.,
Toronto time, two Business Days before the maturity date of such B/As, the
Canadian Borrower shall notify the Canadian Administrative Agent at the Canadian
Administrative Agent's address set forth in Section 9.01 by irrevocable
telephone notice, followed by a notice of rollover on the same day, if the
Canadian Borrower intends to issue B/As on such maturity date to provide for the
payment of such maturing B/As.  If the Canadian Borrower fails to notify the
Canadian Administrative Agent of its intention to issue B/As on such maturity
date, the Canadian Borrower shall provide payment to the Canadian Administrative
Agent on behalf of the C $ Revolving Lenders of an amount equal to the aggregate
face amount of such B/As on the maturity date of such B/As.  If the Canadian
Borrower fails to make such payment, such maturing B/As shall, subject to
satisfaction of the conditions set forth in Section 4.02, be deemed to have been
converted on their maturity date into a Canadian Prime Rate Loan in an amount
equal to the face amount of such B/A as provided in Section 2.07 and the
Canadian Borrower shall on demand pay any losses, costs or penalties that may
have been incurred by the Canadian Administrative Agent or any C $ Revolving
Lender due to the failure of the Canadian Borrower to make such payment.

          (i)  The Canadian Borrower waives presentment for payment and any
other defense, in respect of a B/A accepted and purchased by it pursuant to this
Agreement, that might exist solely by reason of such B/A being held, at the
maturity thereof, by such Lender in its own right and the Canadian Borrower
agrees not to claim any days of grace if such Lender as holder sues the Canadian
Borrower on the B/A for payment of the amount payable by the Canadian Borrower
thereunder.  On the specified maturity date of a B/A, or such earlier date as
may be required or permitted pursuant
<PAGE>

                                                                              87

to the provisions of this Agreement, the Canadian Borrower shall pay, through
the Canadian Administrative Agent, the C $ Revolving Lender that has accepted
and purchased such B/A the full face amount of such B/A and after such payment,
the Canadian Borrower shall have no further liability in respect of such B/A and
such Lender shall be entitled to all benefits of, and be responsible for all
payments due to third parties under, such B/A.

          (j)  If a C $ Revolving Lender grants a participation in a portion
of its rights under this Agreement to a participant under Section 9.04(f), then
in respect of any B/A Borrowing, a portion thereof may, at the option of such
Lender, be by way of Bankers' Acceptance accepted by such participant.  In such
event, the Canadian Borrower shall upon request of the Canadian Administrative
Agent or the C $ Revolving Lender granting the participation execute and deliver
a form of Bankers' Acceptance undertaking in favor of such participant for
delivery to such participant.

          SECTION 2.22.  Spot Exchange Rate Calculations. (a)(i) Not later than
                         --------------------------------
2:00 p.m., Toronto time, on each Calculation Date, the Canadian Administrative
Agent shall (A) determine the Spot Exchange Rate as of such Calculation Date
with respect to Canadian Dollars if at such time C $ Revolving Loans are then
outstanding and (B) give notice thereof to the Canadian Borrower and the C $
Revolving Lenders.

          (ii)  The Spot Exchange Rates determined pursuant to this Section
2.22(a) shall become effective on the second Business Day immediately following
the relevant Calculation Date (a "Reset Date") and shall remain effective until
                                  ----------
the next succeeding Reset Date.

          (b)  Not later than 2:00 p.m., Toronto time, on the Business Day
immediately following the delivery of any notice pursuant to Section 2.08(d) or
2.11(f) in connection with the repayment of C $ Revolving Loans, the Canadian
Administrative Agent shall (i) determine as of such date the Assigned Dollar
Value, based on the Spot Exchange Rate then in effect, of each C $ Revolving
Loan then outstanding (after giving effect to any C $ Revolving Loan repaid in
connection therewith) and (ii) notify the Canadian Borrower and the C $
Revolving Lenders of the results of such determination.

          SECTION 2.23.  Reallocation.  (a) Subject to Section 2.23(b), the
                         -------------
Borrowers may, from time to time (but no more than once in any calendar
quarter), from and after July 1, 2001, until the earlier of (i) the Revolving

Maturity Date and (ii) the termination of the C $ Revolving Commitments and the
Additional Revolving Commitments, upon giving an irrevocable joint written
notice (each, a "Reallocation Notice") to the Canadian Administrative Agent and
                 -------------------
the U.S. Administrative Agent at least ten Business Days prior to the beginning
of the next Fiscal Quarter (including, with respect to any reallocation to be
effective as of July 1, 2001, the Fiscal Quarter ended June 30, 2001),
temporarily reduce (but not below zero), in whole or in part, the C $ Revolving
Commitments or the Additional Revolving Commitments, as applicable.  Each
reduction in the C $ Revolving Commitments shall result in an automatic
corresponding increase in the Additional Revolving Commitments, and each
reduction in the Additional Revolving Commitments shall result in an automatic
and corresponding increase in the C $ Revolving Commitments.  Any amount of C $
Revolving Commitments reallocated under this Section 2.23(a) to Additional
Revolving Commitments will not be available to the Canadian Borrower, and any
amount of Additional Revolving Commitments reallocated under this Section
2.23(a) to C $ Revolving Commitments will not be available to the U.S. Borrower,
in each case unless and until such amounts are reallocated back to the C $
Revolving Commitments or the Additional Revolving Commitments, as applicable, in
accordance with the terms and subject to the conditions of this Section 2.23.

          (b)  The Borrowers shall be permitted to reallocate the C $ Revolving
Commitments and the Additional Revolving Commitments in accordance with this
Section 2.23 subject to the conditions that (i) any such reallocation shall only
be made on, and be effective as of, the first day of a Fiscal Quarter, (ii) each
partial reallocation shall be in an integral multiple of $1,000,000 (or, if
less, the remaining amount of the applicable Commitments being reduced), (iii)
the Total C $ Revolving Commitment shall not be reduced to an amount that is
less than the aggregate C $ Revolving Exposures of the C $ Revolving Lenders at
such time, (iv) the Total Additional Revolving Commitment shall not be reduced
to an amount that is less than the aggregate principal amount of Additional
Revolving Loans outstanding at such time and (v) on the date of any reduction of
the Additional Revolving Commitments (and a corresponding increase in the C $
Revolving Commitments), (A) the representations and warranties set forth in each

at such time are greater than zero) shall be made ratably among the C $
Revolving Lenders based on their respective C $ Revolving Commitments.  Each
increase in the C $ Revolving Commitments (if the C $ Revolving Commitments at
such time are equal to zero) shall be made ratably among the C $ Revolving
Lenders based on their respective Additional Revolving Commitments; provided

that, for this purpose, the Additional Revolving Commitment of any C $ Revolving
Lender that makes Additional Revolving Loans through its Designated U.S.
Affiliate shall be deemed to be equal to the Additional Revolving Commitment of
such Designated U.S. Affiliate. Each reduction in the Additional Revolving
Commitments and each increase in the Additional Revolving Commitments (if the
Additional Revolving Commitments at such time are greater than zero) shall be
made ratably among the Additional Revolving Lenders based on their respective
Additional Revolving Commitments.  Each increase in the Additional Revolving
Commitments (if the Additional Revolving Commitments at such time are equal to
zero) shall be made ratably among the Additional Revolving Lenders based on
their respective C $ Revolving Commitments; provided that, for this purpose, the

its Affiliate that is a C $ Revolving Lender. Promptly after receiving a
Reallocation Notice, the Canadian Administrative Agent or the U.S.
Administrative Agent, as applicable, shall notify each C $ Revolving Lender and
Additional Revolving Lender, as applicable, of the amount of its C $ Revolving
Commitment or Additional Revolving Commitment, as applicable, to be reallocated

          Section 2.24. Increases in C $ Revolving Commitments. (a)
                        --------------------------------------
Notwithstanding anything to the contrary in this Agreement, the Canadian
Borrower may, from time to time (but no more than once in any Fiscal Quarter),
from and after July 1, 2001, until the Revolving Maturity Date, upon giving an
irrevocable written notice (each, a "C $ Commitment Increase Notice") to the
                                     ------------------------------
Canadian Administrative Agent and the U.S. Administrative Agent at least ten
Business Days prior to the beginning of the next Fiscal Quarter (including, with
respect to any increase to be effective as of July 1, 2001, the Fiscal Quarter
ended June 30, 2001), obtain an increase in the C $ Revolving Commitments in
accordance with paragraphs (b) through (f) below, subject to the conditions that
(i) any such increase shall be in an integral multiple of $1,000,000, (ii) on
the date of each such increase, (A) the representations and warranties set forth
in each Loan Document shall be true and correct in all material respects with
the same effect as though made on and as of such date, except to the extent such
representations and warranties expressly relate to an earlier date, and (B)
immediately after giving effect to each such increase no Default or Event of
Default shall have occurred and be continuing and (iii) after giving effect to
each such increase, the Total Additional Revolving Commitment plus the Total C $
Revolving Commitment shall not exceed $75,000,000.

          (b) Each increase in the C $ Revolving Commitments pursuant to this
Section 2.24 shall be effected by the execution and delivery by the Borrowers
and by a Lender or other Person satisfactory to the Administrative Agents (in
either case, that satisfies the definition of C $ Revolving Lender) of a
supplement to this Agreement, in form and substance satisfactory to the
Administrative Agents, pursuant to which such Lender or other Person agrees (i)
to provide a C $ Revolving Commitment or, if such Lender is at the time already
a C $ Revolving Lender, to increase its C $ Revolving Commitment and (ii) if
such Person is not at the time already a Lender, to become a party to this
Agreement as a Lender and to have all the obligations of a Lender hereunder with
respect to its C $ Revolving Commitment.  Any supplement so executed and
delivered in accordance with this Section 2.24 shall be effective to increase
the C $ Revolving Commitments as provided therein (and correspondingly decrease
the U.S. $ Revolving Commitments as provided herein) without the consent of any
other Lenders.

          (c) Each increase in the C $ Revolving Commitments pursuant to this
Section 2.24 shall result in an automatic corresponding decrease in the U.S. $
Revolving Commitments, which corresponding decrease shall (i) if neither (A) the
Person providing such increase in the C $ Revolving Commitments nor (B) an
Affiliate of such Person designated by such Person and agreed to by the
Borrowers and the Administrative Agents is already a U.S. $ Revolving Lender at
the time, be made ratably among the U.S. $ Revolving Lenders based on their
respective U.S. $ Revolving Commitments or (ii) if either (A) the Person
providing such increase in the C $ Revolving Commitments or (B) an Affiliate of
such Person designated by such Person and agreed to by the Borrowers and the
Administrative Agents is already a U.S. $ Revolving Lender at the time, be
allocated first to reduce such Person's (or, with the consent of the Borrowers
and the Administrative Agents, such Affiliate's) U.S. $ Revolving Commitment
and, after such Person's or Affiliate's U.S. $ Revolving Commitment has been
reduced to zero, be made ratably among the remaining U.S. $ Revolving Lenders
based on their respective remaining U.S. $ Revolving Commitments.

          (d) Any increase in the C $ Revolving Commitments pursuant to this
Section 2.24 (and any corresponding reduction in the U.S. $ Revolving
Commitments referred to in paragraph (c) above) shall only be made on, and be
effective as of, the first day of a Fiscal Quarter.

          (e) If, immediately prior to the effectiveness of any increase in the
C $ Revolving Commitments pursuant to this Section 2.24, (i) there are any Loans
outstanding under the C $ Revolving Commitments, then all such Loans shall be
repaid immediately prior to or concurrently with the effectiveness of such
increase or (ii) there are any Loans outstanding under the U.S. $ Revolving
Commitments and clause (ii) of paragraph (c) of this Section 2.24 is applicable
to such increase, then all such Loans shall be repaid immediately prior to or
concurrently with the effectiveness of such increase.

          (f)  Each C $ Commitment Increase Notice shall specify the amount
(expressed in Dollars) of any increase in the C $ Revolving Commitments and the
corresponding decrease in the U.S. $ Revolving Commitments.

Loan Documents.

          SECTION 3.04.  Financial Condition; No Material Adverse Change.  (a)
                         ------------------------------------------------
Holdings has heretofore furnished to the Lenders the consolidated balance sheet
and statements of income, stockholders' equity and cash flows of Holdings and
its Subsidiaries as of and for the Fiscal Year ended December 31, 2000, reported
on by Ernst & Young LLP, independent public accountants.  Such financial

          (b)  Holdings has heretofore furnished to the Lenders Holdings's pro
forma consolidated balance sheet as of December 31, 2000, prepared giving effect
to the Transactions as if the Transactions had occurred on such date.  Such pro
forma consolidated balance sheet (i) has been prepared in good faith based on
the same assumptions used to prepare the pro forma financial statements included

the U.S. Borrower as of the Effective Date to be reasonable), (ii) is based on
the best information available to Holdings and the U.S. Borrower as of the
Effective Date after due inquiry, (iii) accurately reflects all adjustments
necessary to give effect to the Transactions and (iv) presents fairly, in all
material respects, the pro forma financial position of Holdings and its
consolidated Subsidiaries as of December 31, 2000, as if the Transactions had
occurred on such date.

          (c)  Except as disclosed in the financial statements referred to above
or the notes thereto or in the Information Memorandum and except for the
Disclosed Matters, after giving effect to the Transactions, none of Holdings or
the Subsidiaries has, as of the Effective Date, any material contingent
liabilities, unusual long-term commitments or unrealized losses.

                                                                              94

          (b)  Each of Holdings and the Subsidiaries owns, or is licensed to
use, all trademarks, tradenames, copyrights, patents and other intellectual
property material to its business, and the use thereof by Holdings and the
Subsidiaries does not infringe upon the rights of any other Person, except for
any such infringements that, individually or in the aggregate, could not
reasonably be expected to result in a Material Adverse Effect.

          (c)  Schedule 3.05 sets forth the address of each real property that
is owned or leased by Holdings or any Subsidiary as of the Effective Date.

          SECTION 3.06.  Litigation and Environmental Matters.  (a) There are no
                         -------------------------------------
actions, suits or proceedings by or before any arbitrator or Governmental
Authority pending against or, to the knowledge of Holdings or the U.S. Borrower,
threatened against or affecting Holdings or any Subsidiary (i) as to which there
is a reasonable possibility of an adverse determination and that, if adversely
deter  mined, could reasonably be expected, individually or in the aggregate, to
result in a Material Adverse Effect (other than the Disclosed Matters) or (ii)
that involve any of the Loan Documents or the Transactions.

          (b)  Except for the Disclosed Matters and except with respect to any
other matters that, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect, neither Holdings nor any
Subsidiary (i) has failed to comply with any Environmental Law or to obtain,
maintain or comply with any permit, license or other approval required under any
Environmental Law, (ii) has become subject to any Environmental Liability, (iii)
has received notice of any claim with respect to any Environmental Liability or
(iv) knows of any basis for any Environmental Liability.

          (c)  Since the date of this Agreement, there has been no change in the

upon it or its property, except where the failure to do so, individually or in
the aggregate, could not reasonably be expected to result in a Material Adverse
Effect. No Default has occurred and is continuing.

          SECTION 3.08.  Investment and Holding Company Status.  Neither
                         --------------------------------------

subject to regulation under, the Investment Company Act of 1940 or (b) a
"holding company" as defined in, or subject to regulation under, the Public
Utility Holding Company Act of 1935.

          SECTION 3.09.  Taxes.  Each of Holdings and the Subsidiaries has
                         ------
timely filed or caused to be filed all Tax returns and reports required to have
been filed and has paid or caused to be paid all Taxes required to have been
paid by it, except (a) any Taxes that are being contested in good faith by
appropriate proceedings and for which Holdings or such Subsidiary, as

that the failure to do so could not reasonably be expected to result in a
Material Adverse Effect.

          SECTION 3.10.  ERISA.  No ERISA Event has occurred or is reasonably
                         ------
expected to occur that, when taken together with all other such ERISA Events for
which liability is reasonably expected to occur, could reasonably be expected to
result in a Material Adverse Effect.  The present value of all accumulated
benefit obligations under each Plan (based on the assumptions used for purposes
of Statement of Financial Accounting Standards No. 87) did not in the aggregate,
as of the date of the most recent financial statements reflecting such amounts,
exceed the fair market value of the assets of such Plan by an amount which could
reasonably be expected to result in a Material Adverse Effect, and the present
value of all accumulated benefit obligations of all underfunded Plans (based on
the assumptions used for purposes of Statement of Financial Accounting Standards
No. 87) did not in the aggregate, as of the date of the most recent financial
statements reflecting such amounts, exceed the fair market value of the assets
of all such underfunded Plans by an amount which could reasonably be expected to
result in a Material Adverse Effect.

          SECTION 3.11.  Disclosure.  Holdings and the Borrowers have disclosed
                         -----------
to the Lenders all agreements, instruments and corporate or other restrictions
to which Holdings or any Subsidiary is subject, and all other matters known to
any of them, that, individually or in the aggregate, could reasonably be
expected to result in a
<PAGE>

                                                                              96

Material Adverse Effect. Neither the Information Memorandum nor any of the other
reports, financial statements, certificates or other information furnished by or
on behalf of any Loan Party to any Agent or any Lender in connection with the
negotiation of this Agreement or any other Loan Document or delivered hereunder
or thereunder (as modified or supplemented by other information so furnished)
contains any material misstatement of fact or omits to state any material fact
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading (it being recognized by the Agents
and the Lenders that any projections and forecasts provided by Holdings or any
Subsidiary are based on good faith estimates and assumptions believed by
Holdings or such Subsidiary to be reasonable as of the date of the applicable
projections or assumptions and that actual results during the period or periods
covered by any such projections and forecasts may differ from projected or
forecasted results and no representation whatsoever is made with respect to
reports or projections that are included or referred to in or attached to the
Information Memorandum and identified therein as having been provided by Persons
other than Holdings or one of its Affiliates).

each case as of the Effective Date.  The Canadian Borrower is a wholly owned
subsidiary of the U.S. Borrower.

          SECTION 3.13.  Insurance.  Schedule 3.13 sets forth a description of
                         ----------
all insurance maintained by or on behalf of Holdings and the Subsidiaries as of
the Effective Date.  As of the Effective Date, all premiums in respect of such
insurance have been paid.

          SECTION 3.14.  Labor Matters.  Except as set forth in Schedule 3.14,
                         --------------
as of the Effective Date, there are no strikes, lockouts or slowdowns against
Holdings or any Subsidiary pending or, to the knowledge of Holdings or the
Borrower, threatened.  The hours worked by and payments made to employees of
Holdings and the Subsidiaries have been in compliance with the Fair Labor
Standards Act or any other applicable federal, state, local or foreign law
dealing with such matters except where the failure to comply could not
reasonably be expected to result in a Material Adverse Effect.  All payments due
from Holdings or any Subsidiary, or for which any claim may be made against
Holdings or any Subsidiary, on account of wages and employee health and welfare
insurance and other benefits, have been paid or
<PAGE>

                                                                              97

accrued as a liability on the books of Holdings or such Subsidiary except to the
extent that a failure to comply could not reasonably be expected to result in a
Material Adverse Effect. Except as set forth in Schedule 3.14, the consummation
of the Transactions will not give rise to any right of termination or right of
renegotiation on the part of any union under any collective bargaining agreement
to which Holdings or any Subsidiary is bound.

          SECTION 3.15.  Solvency.  Immediately after the consummation of the
                         ---------
Transactions to occur on the Effective Date and immediately following the making
of each Loan made on the Effective Date and after giving effect to the
application of the proceeds of such Loans (and taking into account all rights of
contribution arising by operation of law or otherwise to which any Loan Party
may be entitled and other credit support available to any Subsidiary from
Holdings or any of the other Subsidiaries), (a) the fair value of the assets of
each Loan Party, at a fair valuation, will exceed its debts and liabilities,
subordinated, contingent or otherwise, (b) the present fair saleable value of
the property of each Loan Party will be greater than the amount that will be
required to pay the probable liability of its debts and other liabilities,
subordinated, contingent or otherwise, as such debts and other liabilities
become absolute and matured, (c) each Loan Party will be able to pay its debts
and liabilities, subordinated, contingent or otherwise, as such debts and
liabilities become absolute and matured, and (d) each Loan Party will not have
unreasonably small capital with which to conduct the business in which it is
engaged as such business is now conducted and is proposed to be conducted
following the Effective Date.

          SECTION 3.16.  Senior Debt.  The Obligations constitute "Senior
                         ------------
Indebtedness" under and as defined in each Subordinated Note Indenture and the
documents evidencing or governing all Subordinated Debt referred to in clauses
(e) and (f) of the definition of "Subordinated Debt".

          SECTION 3.17.  Security Interests.  (a)  When executed and delivered,
                         -------------------
the Pledge Agreements (and/or, as applicable, in the case of the Canadian
Borrower or the Canadian Subsidiary Loan Parties, the making of requisite
filings or registrations) will be effective to create in favor of the applicable
Collateral Agent, for the ratable benefit of the applicable Secured Parties or
Canadian Secured Parties, a legal, valid and enforceable security interest in
the Collateral (as defined in the applicable Pledge Agreement) and, when the
portion of the Collateral constituting certificated securities (as defined in
the
<PAGE>

Uniform Commercial Code or such other local law as may apply) is delivered to
the applicable Collateral Agent (and/or, as applicable, in the case of the
Canadian Borrower or the Canadian Subsidiary Loan Parties, the requisite filings
or registrations are made), the Pledge Agreements shall constitute a fully
perfected first priority Lien on, and security interest in, all right, title and
interest of the pledgor thereunder in such Collateral, in each case prior and
superior in right to any other Person.

          (b)  The Security Agreements are effective to create in favor of the
applicable Collateral Agent, for the ratable benefit of the applicable Secured
Parties or Canadian Secured Parties, a legal, valid and enforceable security
interest in the Collateral (as defined in the applicable Security Agreement)
and, when financing statements or such other filings required by local law in
appropriate form are filed in the appropriate filing offices (which, for the
U.S. Subsidiary Loan Parties as of the Effective Date, are the offices specified
on Schedule 6 to the Perfection Certificate), the Security Agreements shall
constitute a fully perfected Lien on, and security interest in, all right, title
and interest of the grantors thereunder in such Collateral to the extent
perfection can be obtained by filing, recording or registering a security
agreement, financing statement or analogous document in the United States or
Canada (other than under vehicle certificate of title statutes), in each case
prior and superior in right to any other Person other than with respect to the
rights of Persons pursuant to Liens expressly permitted by Section 6.03.

          (c)  When the U.S. Security Agreement is filed in the United States
Patent and Trademark Office and the United States Copyright Office, the security
interest created thereunder shall constitute a fully perfected Lien on, and
security interest in, all right, title and interest of the Loan Parties in the
Intellectual Property (as defined in the U.S. Security Agreement) in which a
security interest may be perfected by filing, recording or registering a
security agreement, financing statement or analogous document in the United
States Patent and Trademark Office or the United States Copyright Office, as
applicable, in each case prior and superior in right to any other Person, other
than with respect to the rights of Persons pursuant to Liens expressly permitted
by Section 6.03 (it being understood that subsequent recordings in the United
States Patent and Trademark Office and the United States Copyright Office may be
necessary to perfect a Lien on registered trademarks, trademark applications and
copyrights acquired by the Loan Parties after the date hereof).

behalf and to exercise such powers as are delegated to such Agent by the terms
of the Loan Documents, together with such actions and powers as are reasonably
incidental thereto.  The Canadian Collateral Agent hereby agrees to act as the
fonde de pouvoir (i.e., holder of the power of attorney) of the Canadian Secured
                  ----
Parties to the extent necessary or desirable for the purposes of creating,
maintaining or enforcing any security interest created or established or to be
created or established under any of the Canadian Security Documents including
entering into the Canadian Security Documents and exercising all or any of the
rights, powers, trusts or duties conferred upon the Canadian Collateral Agent
therein or conferred upon the Canadian Collateral Agent hereunder with respect
to such security interest, and each Canadian Secured Party by executing this
Credit Agreement accepts the Canadian Collateral Agent as the fonde de pouvoir
of such Canadian Secured Party for such purposes.

          Each bank serving as an Agent hereunder shall have the same rights and
powers in its capacity as a Lender as any other Lender and may exercise the same
as though it were not an Agent, and such bank and its Affiliates may accept
deposits from, lend money to and generally engage in any kind of business with
Holdings, the Borrowers or any Subsidiary or other Affiliate thereof as if it
were not an Agent hereunder.

                                                                             129

          The Agents shall not have any duties or obligations except those
expressly set forth in the Loan Documents.  Without limiting the generality of
the foregoing, (a) the Agents shall not be subject to any fiduciary or other
implied duties, regardless of whether a Default has occurred and is continuing,
(b) the Agents shall not have any duty to take any discretionary action or
exercise any discretionary powers, except discretionary rights and powers
expressly contemplated by the Loan Documents that the Agents are required to
exercise in writing by the Required Lenders (or such other number or percentage
of the Lenders as shall be necessary under the circumstances as provided in
Section 9.02) and (c) except as expressly set forth in the Loan Documents, the
Agents shall not have any duty to disclose, and shall not be liable for the
failure to disclose, any information relating to Holdings, either Borrower or
any of the Subsidiaries that is communicated to or obtained by such Agent or any
of its Affiliates in any capacity.  No Agent shall be liable for any action
taken or not taken by it with the consent or at the request of the Required
Lenders (or such other number or percentage of the Lenders as shall be necessary
under the circumstances as provided in Section 9.02) or in the absence of its
own gross negligence or wilful misconduct.  No Agent shall be deemed to have
knowledge of any Default unless and until written notice thereof is given to
such Agent by Holdings, either Borrower or a Lender, and no Agent shall be
responsible for or have any duty to ascertain or inquire into (i) any statement,
warranty or representation made in or in connection with any Loan Document, (ii)
the contents of any certificate, report or other document delivered thereunder
or in connection therewith, (iii) the performance or observance of any of the
covenants, agreements or other terms or conditions set forth in any Loan
Document, (iv) the validity, enforceability, effectiveness or genuineness of any
Loan Document or any other agreement, instrument or document or (v) the
satisfaction of any condition set forth in Article IV or elsewhere in any Loan
Document, other than to confirm receipt of items expressly required to be
delivered to such Agent.

          Each Agent shall be entitled to rely upon, and shall not incur any
liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing believed by it to be genuine
and to have been signed or sent by the proper Person.  Each Agent also may rely
upon any statement made to it orally or by telephone and believed by it to be
made by the proper Person, and shall not incur any liability for relying
thereon.  Each Agent may consult with legal counsel (who may be counsel for
either Borrower), independent accountants and
<PAGE>

                                                                             130

other experts selected by it, and shall not be liable for any action taken or
not taken by it in accordance with the advice of any such counsel, accountants
or experts.

          Either Collateral Agent may (and shall at the request of any Loan
Party), without the approval of any other Secured Party, (a) release any
Collateral under any Security Document which is permitted to be sold or disposed
of or otherwise released pursuant to this Agreement and execute and deliver such
releases as may be necessary to terminate of record such Collateral Agent's
security interest in such Collateral, (b) release any Loan Party from its
obligations under the applicable Guarantee Agreement if such Loan Party ceases
to be a Subsidiary pursuant to a transaction which is permitted under this
Agreement and (c) subordinate the interest of such Collateral Agent in any
Collateral to the holder of any Lien on such Collateral which is permitted by
clause (d), (h) or (i) of Section 6.03.  In determining whether any such release
or subordination is permitted under this Agreement, each Collateral Agent (i)
may rely, as to factual matters, on a certificate from either Borrower and (ii)
may (but shall not be obligated to) seek (and, if obtained, rely upon)
instructions from the Required Lenders.  In addition, the Collateral Agents may
release all Collateral upon receipt of written notice from the Administrative
Agents that all obligations of the Loan Parties hereunder and under the other
Loan Documents have been paid in full (other than contingent obligations (A) in
respect of Letters of Credit which have been cash collateralized or otherwise
provided for to the satisfaction of the Issuing Bank and (B) arising under
provisions of this Agreement which by their terms survive termination hereof)
and all Commitments have been terminated.

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

          Any Agent may resign at any time upon 30 days' notice to the Lenders,
the Issuing Bank and the Borrowers. Upon any such resignation, the Required
Lenders shall, with (so long as no Default exists) the consent of the U.S.
<PAGE>

                                                                             131

Borrower (which consent shall not be unreasonably withheld or delayed), have the
right to appoint a successor; provided that, in the case of the resignation of
                              --------
the Canadian Administrative Agent or the Canadian Collateral Agent, Lenders
holding a majority of the C $ Revolving Loans shall, with (so long as no Default
exists) the consent of the Canadian Borrower (which consent shall not be
unreasonably withheld or delayed), have such right.  If no successor shall have
been so appointed by the Required Lenders (or the C $ Revolving Lenders, in the
case of the Canadian Administrative Agent or the Canadian Collateral Agent) and
shall have accepted such appointment within 30 days after the retiring Agent
gives notice of its resignation, then the retiring Agent may, on behalf of the
Lenders and the Issuing Bank, appoint a successor Agent which shall be a bank
with an office in New York, New York, or an Affiliate of any such bank having a
combined capital and surplus of at least $500,000,000 (or in the case of a
successor to the Canadian Administrative Agent or the Canadian Collateral Agent,
a Canadian bank with an office in Toronto having a combined capital and surplus
of at least $500,000,000).  Upon the acceptance of its appointment as an Agent
hereunder by a successor, such successor shall succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Agent, and the
retiring Agent shall be discharged from its duties and obligations hereunder.
The fees payable by the applicable Borrower to a successor Agent shall be the
same as those payable to its predecessor unless otherwise agreed between the
applicable Borrower and such successor. After the applicable Agent's resignation
hereunder, the provisions of this Article VIII and Section 9.03 shall continue
in effect for the benefit of such retiring Agent, its sub-agents and their
respective Related Parties in respect of any actions taken or omitted to be
taken by any of them while it was acting as an Agent.  If no successor Agent has
accepted appointment as the applicable Agent by the date which is 30 days
following a retiring Agent's notice of resignation, the retiring Agent's
resignation shall nevertheless thereupon become effective and the Lenders (or,
in the case of the Canadian Administrative Agent and the Canadian Collateral
Agent, the C $ Revolving Lenders) shall perform all of the duties of such Agent
hereunder until such time, if any, as the Required Lenders appoint a successor
Agent as provided for above.

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

reliance upon any Agent or any other Lender and based on such documents and
information as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement,
any other Loan Document or related agreement or any document furnished hereunder
or thereunder.

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

          (b)  Except as provided in Section 2.20 with respect to an Incremental
Facility Amendment or Section 2.24 with respect to an increase in the C $
Revolving Commitments, neither this Agreement nor any other Loan Document nor

amended or modified except, in the case of this Agreement, pursuant to an
agreement or agreements in writing entered into by Holdings, the Borrowers and
the Required Lenders or, in the case of any other Loan Document, pursuant to an
agreement or agreements in writing entered into by the applicable Agent, and the
Loan Party or Loan Parties that are parties thereto, in each case with the
consent of the Required Lenders; provided that no such agreement shall (i)
                                 --------
increase the Commitment of any Lender without the written consent of such
Lender, (ii) reduce the principal amount of any Loan or LC Disbursement or
reduce the rate of interest thereon, or reduce any fees payable hereunder,
without the written consent of each Lender affected thereby, (iii) postpone the
scheduled date of payment of the principal amount of any Loan or LC
Disbursement, or any interest thereon, or any fees payable hereunder, or reduce
the amount of, waive or excuse any such payment, or postpone the scheduled date
of expiration of any Commitment, without the written consent of each Lender
affected thereby, (iv) change Section 2.18(b) or (c) or 2.11(e) in a manner that
would alter the pro rata sharing of payments required thereby, without the
written consent of each Lender, (v) change any of the provisions of this Section
9.02(b) or the definition of "Required Lenders", "Majority Lenders" or any other
provision of any Loan Document specifying the number or percentage of Lenders
(or Lenders of any Class) required to waive, amend or modify any rights
thereunder or make any determination or grant any consent thereunder, without
the written consent of each Lender (or each Lender of such Class, as the case
may be), (vi) release any Loan Party from its guarantee under the applicable
Guarantee Agreement (except as expressly provided therein) or release the U.S.
Borrower from its Guaranty set forth in Article XI, or limit such Loan Party's
or the U.S. Borrower's liability in respect of such Guarantee Agreement or
Guaranty, as the case may be, without the written consent of each Lender, (vii)
release all or substantially all of the Collateral from the Liens of the
Security Documents (except as expressly provided therein), without the written
consent of each Lender, (viii) change any provisions of any Loan Document in a
manner that by its terms adversely affects the rights in respect of payments due
to Lenders holding Loans of any Class differently than those holding Loans of
any other Class, without the written consent of Lenders holding a majority in
interest of the outstanding Loans and unused Commitments of each affected Class,
or (ix) change Section 2.10(c), or change Section 2.11(c) in a manner that would
alter the order of the application of the payments contemplated by the second
sentence thereof, without the written consent of Lenders holding a majority in
interest of Term Loans; provided, further, that (A) no such agreement

shall amend, modify or otherwise affect the rights or duties of the
Administrative Agents, the Issuing Bank or the Swingline Lender without the
prior written consent of the applicable Administrative Agent, the Issuing Bank
or the Swingline Lender, as the case may be, and (B) any waiver, amendment or
modification of this Agreement that by its terms affects the rights or duties
under this Agreement of the U.S. $ Revolving Lenders (but not the Term Loan
Lenders, the Incremental Term Lenders, the C $ Revolving Lenders and the
Additional Revolving Lenders), the C $ Revolving Lenders and Additional
Revolving Lenders (including any change in the identity of the Canadian
Borrower)(but not the U.S. $ Revolving Lenders, the Term Loan Lenders and the
Incremental Term Lenders), the Term Loan Lenders (but not the Revolving Lenders,
the Additional Revolving Lenders, the C $ Revolving Lenders or the Incremental
Term Lenders) or the Incremental Term Lenders (but not the Revolving Lenders,
the Additional Revolving Lenders, the C $ Revolving Lenders or the Term Loan
Lenders) may be effected by an agreement or agreements in writing entered into
by Holdings, the Borrowers and the requisite percentage in interest of the
affected Class of Lenders. Notwithstanding the foregoing, any provision of this
Agreement may be amended by an agreement in writing entered into by Holdings,
the Borrowers, the Required Lenders and each Agent (and, if their rights or
obligations are affected thereby, the Issuing Bank and the Swingline Lender) if
(i) by the terms of such agreement the Commitment of each Lender not consenting
to the amendment provided for therein shall terminate (but such Lender shall
continue to be entitled to the benefits of Sections 2.15, 2.16, 2.17 and 9.03)
upon the effectiveness of such amendment and (ii) at the time such amendment
becomes effective, each Lender not consenting thereto receives payment in full
of the principal of and interest accrued on each Loan made by it and all other
amounts owing to it or accrued for its account under this Agreement and is
released from its obligations hereunder. In connection with any proposed
amendment, modification, waiver or termination (a "Proposed Change") requiring
                                                   ---------------
the consent of all affected Lenders, if the consent of the Required Lenders to
such Proposed Change is obtained, but the consent to such Proposed Change of
other Lenders whose consent is required is not obtained (any such Lender whose
consent is not obtained as described in this Section 9.02(b) being referred to
as a "Non-Consenting Lender"), then, so long as the Lender that is acting as the
      ---------------------
U.S. Administrative Agent is not a Non-Consenting Lender, at the Borrower's
request, the U.S. Administrative Agent or another assignee that is acceptable to
the U.S. Administrative Agent shall have the right with the U.S. Administrative
Agent's consent and in the U.S. Administrative Agent's sole discretion (but
shall have no

obligation) to purchase from such Non-Consenting Lender, and such Non-Consenting
Lender agrees that it shall, upon the U.S. Administrative Agent's request, sell
and assign to the Lender that is acting as the Administrative Agent or such
other assignee, all of the Commitments, Term Loans and Revolving Exposures of
such Non-Consenting Lender for an amount equal to the principal balance of all
Term Loans and Revolving Loans (and funded participations in Swingline Loans and
unreimbursed LC Disbursements) held by the Non-Consenting Lender and all accrued
interest and fees with respect thereto through the date of sale, such purchase
and sale to be consummated pursuant to an executed Assignment and Acceptance in
accordance with Section 9.04(b).

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

          (b)  The Borrowers shall indemnify the Agents, the Issuing Bank and
each Lender, and each Related Party of any of the foregoing Persons (each such
Person being called an "Indemnitee") against, and hold each Indemnitee harmless
                        ----------
from, any and all losses, claims, damages, liabilities and related expenses,
including the reasonable fees, charges and disbursements of any counsel for any
Indemnitee, incurred by or asserted against any Indemnitee arising out of, in
connection with, or as a result of (i) the execution or delivery of any Loan
Document or any other agreement or

instrument contemplated hereby, the performance by the parties to the Loan
Documents of their respective obligations thereunder or the consummation of the
Transactions or any other transactions contemplated hereby, (ii) any Loan or
Letter of Credit or the use of the proceeds therefrom (including any refusal by
the Issuing Bank to honor a demand for payment under a Letter of Credit if the
documents presented in connection with such demand do not strictly comply with
the terms of such Letter of Credit), (iii) any actual or alleged presence or
release of Hazardous Materials on or from any property currently or formerly
owned or operated by Holdings or any Subsidiary, or any Environmental Liability
related in any way to Holdings or any Subsidiary, or (iv) any actual or
prospective claim, litigation, investigation or proceeding relating to any of
the foregoing, whether based on contract, tort or any other theory and
regardless of whether any Indemnitee is a party thereto; provided that such
                                                         --------
indemnity shall not, as to any Indemnitee, be available to the extent that such
losses, claims, damages, liabilities or related expenses are determined by a
court of competent jurisdiction by final and nonappealable judgment to have
resulted from the gross negligence or wilful misconduct of such Indemnitee.

          (c)  To the extent that either Borrower fails to pay any amount
required to be paid by it to any Agent, the Issuing Bank or the Swingline Lender
under paragraph (a) or (b) of this Section 9.03, each Lender severally agrees to
pay to such Agent, the Issuing Bank or the Swingline Lender, as the case may be,
such Lender's pro rata share (determined as of the time that the applicable
unreimbursed expense or indemnity payment is sought) of such unpaid amount;
provided that the unreimbursed expense or indemnified loss, claim, damage,
--------
liability or related expense, as the case may be, was incurred by or asserted
against such Agent, the Issuing Bank or the Swingline Lender in its capacity as
such.  For purposes hereof, a Lender's "pro rata share" shall be determined
based upon its share of the sum of the total Revolving Exposures, outstanding
Term Loans and unused Commitments at the time.

          (d)  To the extent permitted by applicable law, neither Holdings nor
the Borrowers shall assert, and each hereby waives, any claim against any
Indemnitee, on any theory of liability, for special, indirect, consequential or
punitive damages (as opposed to direct or actual damages) arising out of, in
connection with, or as a result of, this Agreement or any agreement or
instrument contemplated hereby, the Transactions, any Loan or Letter of Credit
or the use of the proceeds thereof.

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

          (f)  Notwithstanding the foregoing, the Canadian Borrower shall not
have any liability pursuant to this Section 9.03 other than to the Canadian
Administrative Agent, the Canadian Collateral Agent and the C $ Revolving
Lenders (and assignees thereof pursuant to Section 9.04 or 10.01)

          SECTION 9.04.  Successors and Assigns.  (a)  The provisions of this
                         -----------------------
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns permitted hereby (including any
Affiliate of the Issuing Bank that issues any Letter of Credit), except that
neither Holdings nor the Borrowers may assign or otherwise transfer any of its
rights or obligations hereunder without the prior written consent of each Lender
(and any attempted assignment or transfer by Holdings or either Borrower without
such consent shall be null and void)(except as contemplated by the second
parenthetical in clause (B) of the second proviso to Section 9.02(b)).  Nothing
in this Agreement, expressed or implied, shall be construed to confer upon any
Person (other than the parties hereto, their respective successors and assigns
permitted hereby (including any Affiliate of the Issuing Bank that issues any
Letter of Credit) and, to the extent expressly contemplated hereby, the Related
Parties of each Agent, the Issuing Bank and the Lenders) any legal or equitable
right, remedy or claim under or by reason of this Agreement.

          (b)  Any Lender may assign to one or more assignees all or a portion

Administrative Agent) shall not be less than (A) $1,000,000, in the case of an
assignment of Term Loans or Term Loan Commitments, or (B) $5,000,000, in the
case of an assignment of Revolving Loans or Revolving Commitments, in each case
unless each of the U.S. Borrower and the U.S. Administrative Agent, or the
Canadian Borrower and the Canadian Administrative Agent, as applicable,
otherwise consent, (iii) each partial assignment shall be made as an assignment
of a proportionate part of all the assigning Lender's rights and obligations
under this Agreement, except that, subject to clause (vi), this clause (iii)
shall not be construed to prohibit the assignment of a proportionate part of all
the assigning Lender's rights and obligations in respect of one Class of
Commitments or Loans, (iv) the parties to each assignment shall execute and
deliver to the applicable Administrative Agent an Assignment and Acceptance,
together with a processing and recordation fee of $3,500, (v) the assignee, if
it shall not be a Lender, shall deliver to the applicable Administrative Agent
an Administrative Questionnaire and (vi) each assignment by a C $ Revolving
Lender (or, in the case of a C $ Revolving Lender that is not a Canadian
Schedule I chartered bank, its Designated U.S. Affiliate) shall be (A) to an

Section 2.23 after giving effect to such assignment, (B) to an assignee that
agrees to make (individually or together with a U.S. Affiliate) C $ Revolving
Loans and Additional Revolving Loans as required pursuant to Section 2.23 (and,
if such assignee is not a Canadian Schedule I chartered bank, such assignee must
designate in the applicable Assignment and Acceptance a U.S. Affiliate for
purposes of making Additional Revolving Loans) and (C) comprised of all or a pro
rata portion of such Lender's C $ Revolving Commitments and Additional Revolving
Commitments; provided, further, that any consent of the Borrowers otherwise

Article VII has occurred and is continuing. Subject to acceptance and recording
thereof pursuant to paragraph (d) of this Section, from and after the effective
date specified in each Assignment and Acceptance the assignee thereunder shall
be a party hereto and, to the extent of the interest assigned by such Assignment
and Acceptance, have the rights and obligations of a Lender under this
Agreement, and the assigning Lender thereunder shall, to the extent of the

obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to

be a party hereto but shall continue to be entitled to the benefits of Sections
2.15, 2.16, 2.17 and 9.03). Any assignment or transfer by a Lender of rights or
obligations under this Agreement that does not comply with this paragraph shall
be treated for purposes of this Agreement as a sale by such Lender of a
participation in such rights and obligations in accordance with paragraph (e) of
this Section.

          (c)  Each of the U.S. Administrative Agent and the Canadian
Administrative Agent, acting for this purpose as an agent of the applicable
Borrower, shall maintain at its address referred to in Section 9.01 a copy of
each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitment of,
and principal amount of the Loans and LC Disbursements owing to, each Lender
pursuant to the terms hereof from time to time (each, a "Register").  The
                                                         --------
entries in a Register shall be conclusive, and Holdings, the Borrowers, the
Administrative Agents, the Issuing Bank and the Lenders may treat each Person
whose name is recorded in a Register pursuant to the terms hereof as a Lender
hereunder for all purposes of this Agreement, notwithstanding notice to the
contrary.  Each Register shall be available for inspection by the Borrowers, the
Collateral Agents, the Issuing Bank and any Lender, at any reasonable time and
from time to time upon reasonable prior notice.

          (d)  Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee, the assignee's completed
Administrative Questionnaire (unless the assignee shall already be a Lender
hereunder), the processing and recordation fee referred to in paragraph (b) of
this Section 9.04 and any written consent to such assignment required by
paragraph (b) of this Section 9.04, the applicable Administrative Agent shall
accept such Assignment and Acceptance and record the information contained
therein in the Register.  No assignment shall be effective for purposes of this
Agreement unless it has been recorded in the Register as provided in this
paragraph.

          (e)  Any Lender may, without notice to or the consent of any party,
sell participations to one or more banks or other entities (a "Participant") in
                                                               -----------
all or a portion of such Lender's rights and obligations under this Agreement
(including all or a portion of its Commitment and the Loans owing to it);
provided that (i) such Lender's obligations under this Agreement shall remain
--------
unchanged, (ii) such Lender shall remain solely responsible to the other parties
hereto for the performance of such obligations
<PAGE>

                                                                             141

and (iii) Holdings, the Borrowers, the Administrative Agents, the Issuing Bank,
the Swingline Lender and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement. Any agreement or instrument pursuant to which
a Lender sells such a participation shall provide that such Lender shall retain
the sole right to enforce the Loan Documents and to approve any amendment,
modification or waiver of any provision of the Loan Documents; provided that
                                                               --------
such agreement or instrument may provide that such Lender will not, without the
consent of the Participant, agree to any amendment, modification or waiver
described in the first proviso to Section 9.02(b) that affects such Participant.
Subject to paragraph (f) of this Section, the Borrowers agree that each
Participant shall be entitled to the benefits of Sections 2.15, 2.16 and 2.17 to
the same extent as if it were a Lender and had acquired its interest by
assignment pursuant to paragraph (b) of this Section. To the extent permitted by
law, each Participant also shall be entitled to the benefits of Section 9.08 as
though it were a Lender, provided such Participant agrees to be subject to
Section 2.18(c) as though it were a Lender.

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

          (g)  In the event that S&P or Moody's shall, after the date that any
Lender becomes a Revolving Lender, downgrade the long-term certificate of
deposit ratings of such Revolving Lender, and the resulting ratings shall be
BBB+ or lower, in the case of S&P, or Baa1 or lower, in the case of Moody's,
then the Issuing Bank shall have the right, but not the obligation, at its own
expense, upon notice to such Lender and the U.S. Administrative Agent, to
replace (or to request the U.S. Borrower to use its reasonable efforts to
replace) such Lender with an assignee (in accordance with and subject to the
restrictions contained in paragraph (b) above), and such Lender hereby agrees to
transfer and assign without representation, warranty or
<PAGE>

                                                                             142

recourse (in accordance with and subject to the restrictions contained in
paragraph (b) above) all its interests, rights and obligations in respect of its
Revolving Commitment to such assignee; provided, however, that (i) no such
                                       --------  -------
assignment shall conflict with any law, rule and regulation or order of any
Governmental Authority and (ii) the Issuing Bank or such assignee, as the case
may be, shall pay to such Lender in immediately available funds on the date of
such assignment the principal of and interest accrued to the date of payment on
the Revolving Loans made by such Lender hereunder and all other amounts accrued
for such Lender's account or owed to it hereunder (in its capacity as a
Revolving Lender).

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

          (i)  Notwithstanding anything to the contrary contained in this
Section 9.04, any Lender (a "Granting Lender") may grant to a special purpose
                             ---------------
funding vehicle (an "SPV"), identified as such in writing from time to time by
                     ---
the Granting Lender to each Agent and the Borrowers, the option to provide to
the Borrowers all or any part of any Loan that such Granting Lender would
otherwise be obligated to make to the Borrowers pursuant to this Agreement;

provided that (i) nothing herein shall constitute a commitment by any SPV to
--------
make any Loan and (ii) if an SPV elects not to exercise such option or otherwise
fails to provide all or any part of such Loan, the Granting Lender shall be
obligated to make such Loan pursuant to the terms hereof.  The making of a Loan
by an SPV hereunder shall utilize the Commitment of the Granting Lender to the
same extent, and as if, such Loan were made by such Granting Lender.  Each party
hereto hereby agrees that no SPV shall be liable for any indemnity or similar
payment obligation under this Agreement (all liability for which shall remain
with the Granting Lender).  In furtherance of the foregoing, each party hereto
hereby agrees (which agreement shall survive the termination of this Agreement)
that, prior to the date that is one year and one day after the payment in full
of all outstanding commercial paper or other senior Debt of any SPV, it will not
institute against, or join any other person in instituting against, such SPV any

bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings
under the laws of the United States of America or any State thereof.  In
addition, notwithstanding anything to the contrary in this Section 9.04, any SPV
may (i) with notice to, but without the prior written consent of, the Borrowers
or any Agent and without paying any processing fee therefor, assign all or a
portion of its interests in any Loans to the Granting Lender or to any financial
institutions (consented to by the Borrowers and each Agent) providing liquidity
and/or credit support to or for the account of such SPV to support the funding
or maintenance of Loans and (ii) disclose on a confidential basis any non-public
information relating to its Loans to any rating agency, commercial paper dealer
or provider of any surety, guarantee or credit or liquidity enhancement to such
SPV.  As this Section 9.04(h) applies to any particular SPV, this Section may
not be amended without the written consent of such SPV.

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

          SECTION 9.06.  Counterparts; Integration; Effectiveness.  This
                         -----------------------------------------
Agreement may be executed in counterparts (and by different parties hereto on
different counterparts), each of which shall constitute an original, but all of
which when taken together shall constitute a single contract.  This Agreement,
the other Loan Documents
<PAGE>

                                                                             144

and any separate letter agreements with respect to fees payable to any Agents
constitute the entire contract among the parties relating to the subject matter
hereof and supersede any and all previous agreements and understandings, oral or
written, relating to the subject matter hereof. Except as provided in Section
4.01, this Agreement shall become effective when it shall have been executed by
the Administrative Agents and when the U.S. Administrative Agent shall have
received counterparts hereof which, when taken together, bear the signatures of
each of the other parties hereto, and thereafter shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and
assigns. Delivery of an executed counterpart of a signature page of this
Agreement by telecopy shall be effective as delivery of a manually executed
counterpart of this Agreement.

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

          SECTION 9.08.  Right of Setoff.  If an Event of Default shall have
                         ----------------
occurred and be continuing, each Lender and each of its Affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other obligations at any time
owing by such Lender or Affiliate to or for the credit or the account of the
applicable Borrower against any of and all the obligations of such Borrower now
or hereafter existing under this Agreement held by such Lender, irrespective of
whether or not such Lender shall have made any demand under this Agreement and
although such obligations may be unmatured. The rights of each Lender under this
Section are in addition to other rights and remedies (including other rights of
setoff) which such Lender may have.  Notwithstanding anything to the contrary
contained in any of the Loan Documents, no proceeds of the exercise of any such
lien, setoff or similar right against the Canadian Borrower or its subsidiaries
shall be applied to the payment of any amounts other than amounts owing by the
Canadian Borrower hereunder in respect of C $ Revolving Borrowings.

County and of the United States District Court of the Southern District of New

enforcement of any judgment, and each of the parties hereto hereby irrevocably
and unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such federal court.  Each of the parties hereto agrees that
a final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law.  Nothing in this Agreement or any other Loan Document shall
affect any right that the Agents, the Issuing Bank or any Lender may otherwise
have to bring any action or proceeding relating to this Agreement or any other
Loan Document against Holdings, the Borrowers or their properties in the courts
of any jurisdiction.

          (c)  Each of Holdings and the Borrowers hereby irrevocably and
unconditionally waives, to the fullest extent it may legally and effectively do
so, any objection which it may now or hereafter have to the laying of venue of
any suit, action or proceeding arising out of or relating to this Agreement or
any other Loan Document in any court referred to in paragraph (b) of this
Section 9.09.  Each of the parties hereto hereby irrevocably waives, to the
fullest extent permitted by law, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such court.

          (d)  Each party to this Agreement irrevocably consents to service of

OR RELATING TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH
PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY
OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B)
ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER
INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS IN THIS SECTION.

                         ----------------
and the Lenders agrees to maintain the confidentiality of the Information (as
defined below) and use the information only in connection with the
administration of this Agreement and the other Loan Documents or in connection
with any other extension of credit or proposed extension of credit to Holdings
or a Subsidiary by the Agents, the Issuing Bank or the Lenders, as applicable,
except that Information may be disclosed (a) to its and its Affiliates'
directors, officers, employees and agents, including accountants, legal counsel
and other advisors in connection with the administration of this Agreement and
the other Loan Documents, and to any direct or indirect contractual counterparty
in swap agreements or to such contractual counterparty's professional advisors
(it being understood that the Persons to whom such disclosure is made will be
informed of the confidential nature of such Information and instructed to keep
such Information confidential), (b) to the extent requested by any regulatory
authority or by the National Association of Insurance Commissioners, (c) to the
extent required by applicable laws or regulations or by any subpoena or similar

from Holdings or the Borrowers relating to Holdings or either Borrower or its
business, other than any such information that is available to the Agents, the
Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by
Holdings or the Borrowers; provided that, in the case of information received
                           --------
from Holdings or the Borrowers after the date hereof, such information is
clearly identified at the time of delivery as confidential. Any Person required
to maintain the confidentiality of Information as provided in this Section 9.12
shall be considered to have complied with its obligation to do so if such Person
has exercised the same degree of care to maintain the confidentiality of such
Information as such Person would accord to its own confidential information.

          SECTION 9.13.  Interest Rate Limitation. Notwithstanding anything
                         -------------------------
herein to the contrary, if at any time the interest rate applicable to any Loan,
together with all fees, charges and other amounts which are treated as interest
on such Loan under applicable law (collectively, the "Charges"), shall exceed
                                                      -------
the maximum lawful rate (the "Maximum Rate") which may be contracted for,

limited to the Maximum Rate and, to the extent lawful, the interest and Charges
that would have been payable in respect of such Loan but were not payable as a
result of the operation of this Section shall be cumulated and the interest and
Charges payable to such Lender in respect of other Loans or periods shall be
increased (but not above the Maximum Rate therefor) until such cumulated amount,
together with interest thereon at the Federal Funds Effective Rate (or, in the
case of amounts owed to C $ Revolving Lenders, the Canadian Prime Rate) to the
date of repayment, shall have been received by such Lender.

          SECTION 9.14.  Designated Senior Indebtedness. The U.S. Borrower

hereunder and under the other Loan Documents to make payments in Dollars or in
Canadian Dollars (the "Obligation Currency") shall not be discharged or

satisfied by any tender or recovery pursuant to any judgment expressed in or
converted into any currency other than the Obligation Currency, except to the
extent that such tender or recovery results in the effective receipt by the
Administrative Agents, the Collateral Agents or a Lender of the full amount of
the Obligation Currency expressed to be payable to such Administrative Agent,
Collateral Agent or Lender under this Agreement or the other Loan Documents. If,
for the purpose of obtaining or enforcing judgment against either of the
Borrowers or any other Loan Party in any court or in any jurisdiction, it
becomes necessary to convert into or from any currency other than the Obligation
Currency (such other currency being hereinafter referred to as the "Judgment

by the U.S. Administrative Agent or, if the U.S. Administrative Agent does not
quote a rate of exchange on such currency, by a known dealer in such currency
designated by the U.S. Administrative Agent) determined, in each case, as of the
date immediately preceding the day on which the judgment is given (such Business
Day being hereinafter referred to as the "Judgment Currency Conversion Date").
                                          ---------------------------------

          (b)  If there is a change in the rate of exchange prevailing between
the Judgment Currency Conversion Date and the date of actual payment of the
amount due, the Borrowers covenant and agree to pay, or cause to be paid, such
additional amounts, if any (but in any event not a lesser amount), as may be
necessary to ensure that the amount paid in the Judgment Currency, when
converted at the rate of exchange prevailing on the date of payment, will
produce the amount of the Obligation Currency which could have been purchased
with the amount of Judgment Currency stipulated in the judgment or judicial
award at the rate of exchange prevailing on the Judgment Currency Conversion
Date.

          (c)  For purposes of determining the Dollar Equivalent or rate of
exchange for this Section, such amounts shall include any premium and costs
payable in connection with the purchase of the Obligation Currency.

          SECTION 10.01.  Implementation of CAM.  (a)  On the CAM Exchange Date,
                          ----------------------
(i) the Commitments shall automatically and without further act be terminated as
provided in Article VII, (ii) each U.S. $ Revolving Lender shall immediately be
deemed to have acquired (and shall promptly make payment therefor to the U.S.
Administrative Agent in accordance with Section 2.04(c)) participations in the
Swingline Loans in an amount equal to such U.S. $ Revolving Lender's Applicable
Percentage of each Swingline Loan outstanding on such date and (iii) the Lenders
shall automatically and without further act (and without regard to the
provisions of Section 9.04) be deemed to have exchanged interests in the Credit
Facilities such that in lieu of the interest of each Lender in each Credit
Facility in which it shall participate as of such date (including such Lender's
interest in the Designated Obligations of each Loan Party in respect of each
such Credit Facility), such Lender shall hold an interest in every one of the
Credit Facilities (including the Designated Obligations (including Swingline
Exposure) of each Loan Party in respect of each such Credit Facility and each LC
Reserve Account established pursuant to Section 10.02 below), whether or not
such Lender shall previously have participated therein, equal to such Lender's
CAM Percentage thereof.  Each Lender and each Loan Party hereby consents and
agrees to the CAM Exchange, and each Lender agrees that the CAM Exchange shall
be binding upon its successors and assigns and any Person that acquires a
participation in its interests in any Credit Facility.  Each Loan Party agrees
from time to time to execute and deliver to the U.S. Administrative Agent all
such notes and other instruments and documents as the U.S. Administrative Agent
shall reasonably request to evidence and confirm the respective interests of the
Lenders after giving effect to the CAM Exchange, and each Lender agrees to
surrender any notes originally received by it in connection with its Loans
hereunder to the U.S. Administrative Agent against delivery of new notes
evidencing its interests in the Credit Facilities; provided, however, that the
                                                   --------  -------

such note, instrument or document shall not affect the validity or effectiveness
of the CAM Exchange.

          (b)  As a result of the CAM Exchange, upon and after the CAM Exchange
Date, each payment received by the Administrative Agents or the Collateral
Agents pursuant to any Loan Document in respect of the Designated Obligations,
and each distribution made by the Collateral Agents pursuant to any Security
Documents in respect of the Designated Obligations, shall be distributed to the
Lenders pro rata in accordance with their respective CAM Percentages.  Any
direct payment received by a Lender upon or after the CAM Exchange Date,
including by way of setoff, in respect of a Designated Obligation shall be paid
over to the U.S. Administrative Agent or the Canadian Administrative Agent, as
applicable, for distribution to the Lenders in accordance herewith.

          SECTION 10.02.  Letters of Credit.  (a)  In the event that on the CAM
                          ------------------
Exchange Date any Letter of Credit shall be outstanding and undrawn in whole or
in part, or any amount drawn under a Letter of Credit shall not have been
reimbursed either by the U.S. Borrower, or with the proceeds of a U.S. $
Revolving Borrowing, each U.S. $ Revolving Lender shall promptly pay over to the
U.S. Administrative Agent, in immediately available funds, an amount equal to
such U.S. $ Revolving Lender's Applicable Percentage (as notified to such Lender
by the U.S. Administrative Agent) of such Letter of Credit undrawn face amount
or (to the extent it has not already done so) such Letter of Credit unreimbursed
drawing, together with interest thereon from the CAM Exchange Date to the date
on which such amount shall be paid to the U.S. Administrative Agent at the rate
that would be applicable at the time to an ABR U.S. $ Revolving Loan in a
principal amount equal to such amount, as the case may be.  The U.S.
Administrative Agent shall establish a separate account or accounts for each
Lender (each, an "LC Reserve Account") for the amounts received with respect to
                  ------------------
each such Letter of Credit pursuant to the preceding sentence.  The U.S.
Administrative Agent shall deposit in each Lender's LC Reserve Account such
Lender's CAM Percentage of the amounts received from the U.S. $ Revolving
Lenders as provided above.  The U.S. Administrative Agent shall have sole
dominion and control over each LC Reserve Account, and the amounts deposited in
each LC Reserve Account shall be held in such LC Reserve Account until withdrawn
as provided in paragraph (b), (c), (d) or (e) below.  The U.S. Administrative
Agent shall maintain records enabling it to determine the amounts paid over to
it and deposited in the LC Reserve Accounts in respect of
<PAGE>

                                                                             151

each Letter of Credit and the amounts on deposit in respect of each Letter of
Credit attributable to each Lender's CAM Percentage. The amounts held in each
Lender's LC Reserve Account shall be held as a reserve against the LC Exposure,
shall be the property of such Lender, shall not constitute Loans to or give rise
to any claim of or against any Loan Party and shall not give rise to any
obligation on the part of any Borrower to pay interest to such Lender, it being
agreed that the reimbursement obligations in respect of Letters of Credit shall
arise only at such times as drawings are made thereunder, as provided in Section
2.05.

          (b)  In the event that after the CAM Exchange Date any drawing shall
be made in respect of a Letter of Credit, the U.S. Administrative Agent shall,
at the request of the Issuing Bank, withdraw from the LC Reserve Account of each
Lender any amounts, up to the amount of such Lender's CAM Percentage of such
drawing, deposited in respect of such Letter of Credit and remaining on deposit
and deliver such amounts to the Issuing Bank, as applicable, in satisfaction of
the reimbursement obligations of the U.S. $ Revolving Lenders under Section
2.05(e) (but not of the U.S. Borrower under Section 2.05(f)).  In the event any
U.S. $ Revolving Lender shall default on its obligation to pay over any amount
to the U.S. Administrative Agent in respect of any Letter of Credit as provided
in this Section 10.02, the applicable Issuing Bank shall, in the event of a
drawing thereunder, have a claim against such U.S. $ Revolving Lender to the
same extent as if such Lender had defaulted on its obligations under Section
2.05(e), but shall have no claim against any other Lender in respect of such
defaulted amount, notwithstanding the exchange of interests in the U.S.
Borrower's reimbursement obligations pursuant to Section 10.01.  Each other
Lender shall have a claim against such defaulting U.S. $ Revolving Lender for
any damages sustained by it as a result of such default, including, in the event
such Letter of Credit shall expire undrawn, its CAM Percentage of the defaulted
amount.

          (c)  In the event that after the CAM Exchange Date any Letter of
Credit shall expire undrawn, the U.S. Administrative Agent shall withdraw from
the LC Reserve Account of each Lender the amount remaining on deposit therein in
respect of such Letter of Credit and distribute such amount to such Lender.

          (d)  With the prior written approval of the U.S. Administrative Agent
and the applicable Issuing Bank (not to be unreasonably withheld), any Lender
may withdraw the amount held in its LC Reserve Account in respect of the undrawn
amount of any Letter of Credit.  Any Lender making such a withdrawal shall be
unconditionally obligated, in the
<PAGE>

                                                                             152

event there shall subsequently be a drawing under such Letter of Credit, to pay
over to the U.S. Administrative Agent, for the account of the Issuing Bank, on
demand, its CAM Percentage of such drawing.

          (e)  Pending the withdrawal by any Lender of any amounts from its LC
Reserve Account as contemplated by the above paragraphs, the U.S. Administrative
Agent will, at the direction of such Lender and subject to such rules as the
U.S. Administrative Agent may prescribe for the avoidance of inconvenience,
invest such amounts in Cash Equivalent Investments.  Each Lender that has not
withdrawn its CAM Percentage of amounts in its LC Reserve Account as provided in
paragraph (d) above shall have the right, at intervals reasonably specified by
the U.S. Administrative Agent, to withdraw the earnings on investments so made
by the U.S. Administrative Agent with amounts in its LC Reserve Account and to
retain such earnings for its own account.

          SECTION 10.03.  Conversion.  In the event the CAM Exchange Date shall
                          -----------
occur, Obligations owed by the Loan Parties denominated in Canadian Dollars
shall, automatically and with no further act required, be converted to
obligations of the same Loan Parties denominated in Dollars. Such conversion
shall be effected based upon the Spot Exchange Rate in effect with respect to
Canadian Dollars on the CAM Exchange Date.  On and after any such conversion,
all amounts accruing and owed to any Lender in respect of its Obligations shall
accrue and be payable in Dollars at the rates otherwise applicable hereunder
(and, in the case of interest on Loans, at the default rate applicable to ABR
Loans hereunder).  Notwithstanding the foregoing provisions of this Section
10.03, any Lender may, by notice to the U.S. Borrower and the U.S.
Administrative Agent prior to the CAM Exchange Date, elect not to have the
provisions of this Section 10.03 apply with respect to all Obligations owed to
such Lender immediately following the CAM Exchange Date, and, if such notice is
given, all Obligations owed to such Lender immediately following the CAM
Exchange Date shall remain designated in Canadian Dollars.

note issued by the Canadian Borrower, and the full and punctual payment of all
other amounts payable by the Canadian Borrower under this Agreement. Upon
failure by the Canadian Borrower to pay punctually any such amount, the U.S.
Borrower shall forthwith on demand pay the amount not so paid at the place, in
the currency and in the manner specified in this Agreement. In addition (and
without limiting the foregoing), upon any Loan to the Canadian Borrower being
declared or otherwise becoming immediately due and payable pursuant to Article
VII, the U.S. Borrower shall forthwith on demand pay all amounts payable in
respect of such Loan at the place, in the currency and in the manner specified
in this Agreement.

          SECTION 11.02.  Guaranty Unconditional.  The obligations of the U.S.
                          -----------------------
Borrower under this Section shall be absolute, unconditional and irrevocable
and, without limiting the generality of the foregoing, shall not be released,
discharged or otherwise affected by:

          (a) any extension, renewal, settlement, compromise, waiver or release
     in respect of any obligation of the Canadian Borrower under this Agreement
     or any promissory note issued hereunder, by operation of law or otherwise;

          (b) any modification or amendment of or supplement to this Agreement
     or any promissory note issued hereunder;

          (c) any release, impairment, non-perfection or invalidity of any other
     guaranty or of any direct or indirect security for any obligation of the
     Canadian Borrower under this Agreement or any promissory note issued
     hereunder;

          (d) any change in the corporate existence, structure or ownership of
     the Canadian Borrower or any insolvency, bankruptcy, reorganization or
     other similar proceeding affecting the Canadian Borrower or the Canadian
     Borrower's assets or any resulting release or discharge of any obligation
     of the Canadian Borrower contained in this Agreement or any promissory note
     issued hereunder;

          (e) the existence of any claim, set-off or other right which the U.S.
     Borrower may have at any time against the Canadian Borrower, any Agent, any
     Lender or any other Person, whether in connection herewith or any unrelated
     transaction; provided that nothing herein

     shall prevent the assertion of any such claim by separate suit or
     compulsory counterclaim;

          (f) any invalidity or unenforceability relating to or against the
     Canadian Borrower for any reason of this Agreement or any promissory note
     issued hereunder, or any provision of applicable law or regulation
     purporting to prohibit the payment by the Canadian Borrower of the
     principal of or interest on any Loan or promissory note issued hereunder or
     any other amount payable by the Canadian Borrower under this Agreement; or

          (g) any other act or omission to act or delay of any kind by the
     Canadian Borrower, any Agent, any Lender or any other Person or any other
     circumstance whatsoever which might, but for the provisions of this
     paragraph, constitute a legal or equitable discharge of the Canadian
     Borrower's obligations hereunder.

          SECTION 11.03.  Discharge only upon Payment in Full: Reinstatement in
                          -----------------------------------------------------
Certain Circumstances.  The U.S. Borrower's obligations as guarantor hereunder
----------------------
shall remain in full force and effect until the Commitments shall have
terminated and all obligations of the Canadian Borrower under this Agreement and
each promissory note issued hereunder shall have been paid in full.  If at any
time any payment of principal, interest or any other amount payable by the
Canadian Borrower under this Agreement or any promissory note issued hereunder
is rescinded or must be otherwise restored or returned upon the insolvency,
bankruptcy or reorganization of the Canadian Borrower or otherwise, the Canadian
Borrower's obligations hereunder with respect to such payment shall be
reinstated as though such payment had been due but not made at such time.

          SECTION 11.04.  Waiver by the U.S. Borrower.  The U.S. Borrower
                          ----------------------------
irrevocably waives acceptance hereof, presentment, demand, protest and any
notice not provided for herein, as well as any requirement that at any time any
action be taken by any Person against the Canadian Borrower or any other Person.

          SECTION 11.05.  Subrogation.  Notwithstanding any payment made by or
                          ------------
for the account of the Canadian Borrower pursuant to this Section, the U.S.
Borrower shall not be subrogated to any right of any Agent or any Lender until
such time as the Agents and the Lenders shall have received final payment in
cash of the full amount of all obligations of the Canadian Borrower hereunder.

payment of any amount payable by the Canadian Borrower under this Agreement or
any promissory note issued hereunder is stayed upon the insolvency, bankruptcy

Agent made at the request of the Required Lenders.

                                      -----------    --------  -------
liability of each of the undersigned hereunder shall be limited to the maximum
amount of the Liabilities which such undersigned may guaranty without violating
any fraudulent conveyance or fraudulent transfer law.

     Each of the undersigned agrees that upon the occurrence of any Event of
Default under clause (i) or (j) of Article VII of the Credit Agreement, and if
such event shall occur at a time when any of the Liabilities may not then be due
and payable, such undersigned will pay to the U.S. Collateral Agent for the
account of the Secured Parties forthwith the full amount which would be payable
hereunder by such undersigned if all Liabilities were then due and payable.

     To secure all obligations of each of the undersigned hereunder, the U.S.
Collateral Agent and each other Secured Party shall have a lien on and security
interest in (and may, without demand or notice of any kind, at any time and from
time to time when any amount shall be due and payable by such undersigned
hereunder, appropriate and apply toward the payment of such amount, in such
order of application as the U.S. Collateral Agent or the other Secured Parties
may elect, in accordance with the Credit Agreement) any and all balances,
credits, deposits, accounts or moneys of or in the name of such undersigned now
or hereafter with the U.S. Collateral Agent or such other Secured Party and any
and all property of every kind or description of or

                                       2
<PAGE>

in the name of such undersigned now or hereafter, for any reason or purpose
whatsoever, in the possession or control of, or in transit to, the U.S.
Collateral Agent or such other Secured Party or any agent or bailee for the U.S.
Collateral Agent or such other Secured Party.

     This Guaranty shall in all respects be a continuing, irrevocable, absolute
and unconditional guaranty of payment and performance and not only
collectibility, and shall remain in full force and effect (notwithstanding,
without limitation, the dissolution of any of the undersigned, that at any time
or from time to time no Liabilities are outstanding or any other circumstance)
until all Commitments have terminated and all Liabilities have been paid in full
(subject to reinstatement as provided in the immediately following paragraph).

     The undersigned further agree that if at any time all or any part of any
payment theretofore applied by the U.S. Collateral Agent or any other Secured
Party to any of the Liabilities is or must be rescinded or returned by the U.S.
Collateral Agent or such other Secured Party for any reason whatsoever
(including, without limitation, the insolvency, bankruptcy or reorganization of
the Borrower or any of the undersigned), such Liabilities shall, for the
purposes of this Guaranty, to the extent that such payment is or must be
rescinded or returned, be deemed to have continued in existence, notwithstanding
such application by the U.S. Collateral Agent or such other Secured Party, and
(notwithstanding anything herein to the contrary) this Guaranty shall continue
to be effective or be reinstated, as the case may be, as to such Liabilities,
all as though such application by the U.S. Collateral Agent or such other
Secured Party had not been made.

     The U.S. Collateral Agent or any other Secured Party may, from time to
time, at its sole discretion and without notice to the undersigned (or any of
them), take any or all of the following actions: (a) retain or obtain a security
interest in any property to secure any of the Liabilities or any obligation
hereunder, (b) retain or obtain the primary or secondary obligation of any
obligor or obligors, in addition to the undersigned, with respect to any of the
Liabilities, (c) extend or renew any of the Liabilities for one or more periods
(whether or not longer than the original period), alter or exchange any of the
Liabilities, or release or compromise any obligation of any of the undersigned
hereunder or any obligation of any nature of any other obligor with respect to
any of the Liabilities, (d) release its security interest in, or surrender,
release or permit any substitution or exchange for, all or any part of any
property securing any of the Liabilities or any obligation hereunder, or extend
or renew for one or more periods (whether or not longer than the original
period) or release, compromise, alter or

                                       3
<PAGE>

exchange any obligations of any nature of any obligor with respect to any such
property, and (e) resort to the undersigned (or any of them) for payment of any
of the Liabilities when due, whether or not the U.S. Collateral Agent or such
other Secured Party shall have resorted to any property securing any of the
Liabilities or any obligation hereunder or shall have proceeded against any
other of the undersigned or any other obligor primarily or secondarily obligated
with respect to any of the Liabilities.

     Any amounts received by the U.S. Collateral Agent or any other Secured
Party from whatever source on account of the Liabilities may be applied by it
toward the payment of the Liabilities in accordance with the Credit Agreement;
and, notwithstanding any payments made by or for the account of any of the
undersigned pursuant to this Guaranty, the undersigned shall not be subrogated
to any rights of the U.S. Collateral Agent or any other Secured Party until such
time as this Guaranty shall have been discontinued as to all of the undersigned
and the U.S. Collateral Agent and the other Secured Parties shall have received
payment of the full amount of all Liabilities of the undersigned hereunder.

     The undersigned hereby expressly waive: (a) notice of the acceptance by the
U.S. Collateral Agent or any other Secured Party of this Guaranty, (b) notice of
the existence or creation or non-payment of all or any of the Liabilities, (c)
presentment, demand, notice of dishonor, protest, and all other notices
whatsoever, and (d) all diligence in collection or protection of or realization
upon any Liabilities or any security for or guaranty of any Liabilities.

     Each of the undersigned further agrees to pay all expenses (including
reasonable attorneys' fees and legal expenses) paid or incurred by the U.S.
Collateral Agent or any other Secured Party in endeavoring to collect the
Liabilities of such undersigned, or any part thereof, and in enforcing this
Guaranty against such undersigned.

     The creation or existence from time to time of additional Liabilities to
the U.S. Collateral Agent or the other Secured Parties or any of them is hereby
authorized, without notice to the undersigned (or any of them), and shall in no
way affect or impair the rights of the U.S. Collateral Agent or the other
Secured Parties or the obligations of the undersigned under this Guaranty.

     The U.S. Collateral Agent and any other Secured Party may from time to
time, without notice to the undersigned (or any of them), assign or transfer any
or all of the Liabilities or any interest therein; and, notwithstanding any such
assignment or

                                       4
<PAGE>

transfer or any subsequent assignment or transfer thereof, such Liabilities
shall be and remain Liabilities for the purposes of this Guaranty, and each and
every immediate and successive assignee or transferee of any of the Liabilities
or of any interest therein shall, to the extent of the interest of such assignee
or transferee in the Liabilities, be entitled to the benefits of this Guaranty
to the same extent as if such assignee or transferee were a Secured Party.

     No delay on the part of the U.S. Collateral Agent or any other Secured
Party in the exercise of any right or remedy shall operate as a waiver thereof,
and no single or partial exercise by the U.S. Collateral Agent or any other
Secured Party of any right or remedy shall preclude any other or further
exercise thereof or the exercise of any other right or remedy; nor shall any
modification or waiver of any provision of this Guaranty be binding upon the
U.S. Collateral Agent or any other Secured Party except as expressly set forth
in a writing duly signed and delivered on behalf of the U.S. Collateral Agent
(or, if at any time there is no U.S. Collateral Agent, the Required Lenders). No
action of the U.S. Collateral Agent or any other Secured Party permitted
hereunder shall in any way affect or impair the rights of the U.S. Collateral
Agent or any other Secured Party or the obligations of the undersigned under
this Guaranty. For purposes of this Guaranty, Liabilities shall include all
obligations of the Borrower to the U.S. Collateral Agent or any other Secured
Party arising under or in connection with any Loan Document, notwithstanding any
right or power of the Borrower or anyone else to assert any claim or defense as
to the invalidity or unenforceability of any obligation, and no such claim or
defense shall affect or impair the obligations of the undersigned hereunder.

     Pursuant to the Credit Agreement, (a) this Guaranty has been delivered to
the U.S. Collateral Agent and (b) the U.S. Collateral Agent has been authorized
to enforce this Guaranty on behalf of itself and each of the other Secured
Parties. All payments by the undersigned pursuant to this Guaranty shall be made
to the U.S. Collateral Agent for application as set forth in the Credit
Agreement or, if there is no U.S. Collateral Agent, to the Secured Parties for
their ratable benefit.

     This Guaranty shall be binding upon the undersigned and the successors and
assigns of the undersigned; and to the extent that the Borrower or any of the
undersigned is a partnership, corporation, limited liability company or other
entity, all references herein to the Borrower and to the undersigned,
respectively, shall be deemed to include any successor or successors, whether
immediate or remote, to such partnership, corporation, limited liability company
or other entity. The term "undersigned" as used herein shall mean all parties
executing

                                       5
<PAGE>

this Guaranty and each of them, and all such parties shall be jointly and
severally obligated hereunder.

     This Guaranty shall be construed in accordance with and governed by the law
of the State of New York. Wherever possible each provision of this Guaranty
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Guaranty shall be prohibited by or
invalid under such law, such provision shall be ineffective to the extent of
such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Guaranty.

     This Guaranty may be executed in any number of counterparts and by the
different parties hereto on separate counterparts, and each such counterpart
shall be deemed to be an original but all such counterparts shall together
constitute one and the same Guaranty. At any time after the date of this
Guaranty, one or more additional persons or entities may become parties hereto
by executing and delivering to the U.S. Collateral Agent a counterpart of this
Guaranty. Immediately upon such execution and delivery (and without any further
action), each such additional person or entity will become a party to, and will
be bound by all of the terms of, this Guaranty.

     This Guaranty is secured pursuant to a Third Restated U.S. Security
Agreement dated as of even date herewith (as amended or otherwise modified from
time to time) and may be secured by one or more other agreements (including,
without limitation, one or more pledge agreements, mortgages, deeds of trust or
other similar documents).

     This Guaranty amends and restates in its entirety the Existing Guaranty
which, after the effectiveness hereof, shall no longer be effective (except for
any provisions thereof which by their terms survive, or may be reinstated, after
terminations thereof).

     ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER OR IN CONNECTION WITH
THIS GUARANTY OR ANY OTHER LOAN DOCUMENT, SHALL BE BROUGHT AND MAINTAINED
EXCLUSIVELY IN THE COURTS OF THE STATE OF NEW YORK OR IN THE UNITED STATES
DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK; PROVIDED, HOWEVER, THAT
                                                      --------  -------
ANY SUIT SEEKING ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE
BROUGHT, AT THE U.S. COLLATERAL AGENT'S OPTION, IN THE COURTS OF ANY
JURISDICTION WHERE SUCH COLLATERAL OR OTHER PROPERTY MAY BE FOUND. EACH OF THE
UNDERSIGNED HEREBY EXPRESSLY AND IRREVOCABLY SUBMITS TO THE JURISDICTION OF THE
COURTS OF THE STATE OF NEW YORK AND OF THE UNITED STATES DISTRICT COURT FOR THE
SOUTHERN DISTRICT OF NEW YORK FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET
FORTH ABOVE. EACH OF THE UNDERSIGNED FURTHER

                                       6

IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE
PREPAID, TO FIVE GREENWICH OFFICE PARK, GREENWICH, CONNECTICUT 06830 (OR SUCH
OTHER ADDRESS AS IT SHALL HAVE SPECIFIED IN WRITING TO THE U.S. COLLATERAL AGENT
AS ITS ADDRESS FOR NOTICES HEREUNDER) OR BY PERSONAL SERVICE WITHIN OR WITHOUT
THE STATE OF NEW YORK. EACH OF THE UNDERSIGNED HEREBY EXPRESSLY AND IRREVOCABLY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW
OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY
SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN
BROUGHT IN AN INCONVENIENT FORUM. TO THE EXTENT THAT ANY OF THE UNDERSIGNED HAS
OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY COURT OF FROM ANY
LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT,
ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS
PROPERTY, SUCH UNDERSIGNED HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF
ITS OBLIGATIONS UNDER THIS GUARANTY AND THE OTHER LOAN DOCUMENTS.

     EACH OF THE UNDERSIGNED, AND (BY ACCEPTING THE BENEFITS HEREOF) EACH OF THE
U.S. COLLATERAL AGENT AND EACH OTHER SECURED PARTY, HEREBY WAIVES ANY RIGHT TO A
TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS UNDER
THIS GUARANTY OR ANY OTHER LOAN DOCUMENT AND ANY AMENDMENT, INSTRUMENT, DOCUMENT
OR AGREEMENT DELIVERED OR WHICH MAY IN THE FUTURE BE DELIVERED IN CONNECTION
HEREWITH OR THEREWITH OR ARISING FROM ANY FINANCING RELATIONSHIP EXISTING IN
CONNECTION WITH ANY OF THE FOREGOING, AND AGREES THAT ANY SUCH ACTION OR
PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY.

     foregoing, all certificates and instruments representing or evidencing such
     property, and all cash, securities, interest, dividends, rights and other

     otherwise distributed in respect of or in exchange for any or all thereof;
     and

          D. All products and proceeds of all of the foregoing.

<PAGE>

65% of the stock of any class of any Foreign Issuer to the extent that the
pledge of any greater percentage could result in adverse tax consequences to

receipt and in due form for transfer (i.e., endorsed in blank or accompanied by

dividends which such Pledgor is entitled to receive and retain pursuant to

(or at the time of any future delivery, pledge, assignment or transfer thereof
will be) the legal and equitable owner of such Pledgor's Collateral free and
clear of all liens, security interests and encumbrances of every description
whatsoever other than the security interest created hereunder; (b) the pledge
and delivery of such Pledgor's Collateral pursuant to this Agreement will create
a valid perfected security interest in such Pledgor's Collateral in favor of the
U.S. Collateral Agent for the benefit of the Secured Parties; (c) all shares of
stock referred to in Schedule I hereto are duly authorized, validly issued,
                     ----------

Schedule I hereto, such Pledgor's Collateral represents on the date hereof not
----------

information contained on Schedule I hereto with respect to such Pledgor is true
                         ----------

Agreement or with the express prior written consent of the U.S. Collateral
Agent, sell, assign, exchange, pledge, encumber or otherwise transfer, or grant

pledged hereunder, or otherwise diminish or impair any of its rights in, to or
under any of such Pledgor's Collateral; (ii) shall execute such Uniform
Commercial Code financing statements and other documents (and pay the costs of
filing and recording or re-filing and re-recording the same in all public
offices reasonably deemed necessary or appropriate by the U.S. Collateral Agent)
and do such other acts and things, all as the U.S. Collateral Agent may from
time to time reasonably request, to establish and maintain a valid, perfected
security interest in such Pledgor's Collateral (free of all other liens, claims
and rights of third parties whatsoever) to secure the performance and payment of
the Liabilities; (iii) will execute and deliver to the U.S. Collateral Agent
such stock powers and similar documents relating to such Pledgor's Collateral,
satisfactory in form and substance to the U.S. Collateral Agent, as the U.S.
Collateral Agent may reasonably request; and (iv) will furnish the U.S.
Collateral Agent or any Secured Party such information concerning such Pledgor's
Collateral as the U.S. Collateral Agent or such Secured Party may from time to
time reasonably request, and will permit the U.S. Collateral Agent or any other
Secured Party or any designee of the U.S.

to such Pledgor's Collateral, and will, upon request of the U.S. Collateral

or compromise or renew for any period (whether or not longer than the original
period) any obligations of any nature of any party with respect thereto, and (f)
take control of any proceeds of the Collateral.

     5.   Voting Rights, Dividends, etc. (a) Notwithstanding certain provisions
          -----------------------------
of Section 4 hereof, so long as the U.S. Collateral Agent has not given the
notice referred to in paragraph (b) below:

          A. The Pledgors shall be entitled to exercise any and all voting or
     consensual rights and powers and stock purchase or subscription rights
     relating or pertaining to the Collateral or any part thereof for any
     purpose; provided, however, that each Pledgor agrees that it will not
              --------  -------
     exercise any such right or power in any manner which would have a material
     adverse effect on the value of the Collateral.

          B. The Pledgors shall be entitled to receive and retain any and all
     lawful dividends payable in respect of the Collateral which are paid in
     cash by any Issuer if such dividends are permitted by the Credit Agreement,
     but all dividends and distributions in respect of the Collateral or any
     part thereof made in shares of stock or securities or other property or
     representing any return of capital, whether resulting from a subdivision,
     combination or reclassification of Collateral or any part thereof or
     received in exchange for Collateral or any part thereof or as a result of
     any merger, consolidation, acquisition or other exchange of assets to which
     any Issuer may be a party or otherwise or as a result of any exercise of
     any stock purchase or subscription right, shall be and become part of the
     Collateral hereunder and, if received by any Pledgor, shall be forthwith
     delivered to the U.S. Collateral Agent in due form for transfer (i.e.,
     endorsed in blank or accompanied by

                                       5
<PAGE>

     undated stock or bond powers executed in blank) to be held for the purposes
     of this Agreement.

          C. The U.S. Collateral Agent shall execute and deliver, or cause to be
     executed and delivered, to the Pledgors all proxies, powers of attorney,
     dividend orders and other instruments as any Pledgor may request for the
     purpose of enabling such Pledgor to exercise the rights and powers which it
     is entitled to exercise pursuant to clause (A) above and to receive the
                                         ----------
     dividends which it is authorized to retain pursuant to clause (B) above.
                                                            ----------

     (b) Upon notice from the U.S. Collateral Agent during the existence of a
Default, and so long as the same shall be continuing, all rights and powers
which the Pledgors are entitled to exercise pursuant to Section 5(a)(A) hereof,
                                                        ---------------
and all rights of the Pledgors to receive and retain dividends pursuant to
Section 5(a)(B) hereof, shall forthwith cease, and all such rights and powers
---------------
shall thereupon become vested in the U.S. Collateral Agent which shall have,
during the continuance of such Default, the sole and exclusive authority to
exercise such rights and powers and to receive such dividends. Any and all money
and other property paid over to or received by the U.S. Collateral Agent
pursuant to this paragraph (b) shall be retained by the U.S. Collateral Agent as
                 -------------
additional Collateral hereunder and applied in accordance with the provisions
hereof.

     6. Remedies. Whenever a Default shall exist, the U.S. Collateral Agent may
        --------
exercise from time to time any rights and remedies available to it under the
Uniform Commercial Code as in effect in New York or otherwise available to it.
Without limiting the foregoing, whenever a Default shall exist the U.S.
Collateral Agent (a) may, to the fullest extent permitted by applicable law,
without notice, advertisement, hearing or process of law of any kind, (i) sell
any or all of the Collateral, free of all rights and claims of any Pledgor
therein and thereto, at any public or private sale or brokers' board and (ii)
bid for and purchase any or all of the Collateral at any such public sale and
(b) shall have the right, for and in the name, place and stead of the applicable
Pledgor, to execute endorsements, assignments, stock powers and other
instruments of conveyance or transfer with respect to all or any of the
Collateral. Each Pledgor hereby expressly waives, to the fullest extent
permitted by applicable law, any and all notices, advertisements, hearings or
process of law in connection with the exercise by the U.S. Collateral Agent of
any of its rights and remedies during the continuance of a Default. Any
notification of intended disposition of any of the Collateral shall be deemed
reasonably and properly given if given at least ten (10) days before such
disposition. Any proceeds of any of the Collateral may be applied by the U.S.
Collateral Agent to the payment of expenses in connection with the Collateral,
including, without limitation, reasonable attorneys' fees and legal expenses,
and any balance of such proceeds may be applied by the U.S. Collateral Agent
toward the ratable payment of the Liabilities (and, after payment in full of all
Liabilities, any excess shall be delivered to the applicable Pledgor or as a
court of competent jurisdiction shall direct).

     The U.S. Collateral Agent is hereby authorized to comply with any
limitation or restriction in connection with any sale of Collateral as it may be
advised by counsel is necessary in order to (a) avoid any violation of
applicable law (including, without limitation, compliance with such

                                       6
<PAGE>

procedures as may restrict the number of prospective bidders and purchasers
and/or further restrict such prospective bidders or purchasers to persons or
entities who will represent and agree that they are purchasing for their own
account for investment and not with a view to the distribution or resale of such
Collateral) or (b) obtain any required approval of the sale or of the purchase
by any governmental regulatory authority or official, and each Pledgor agrees
that such compliance shall not result in such sale being considered or deemed
not to have been made in a commercially reasonable manner and that the U.S.
Collateral Agent shall not be liable or accountable to any Pledgor for any
discount allowed by reason of the fact that such Collateral is sold in
compliance with any such limitation or restriction.

     7. General. The U.S. Collateral Agent shall be deemed to have exercised
        -------
reasonable care in the custody and preservation of the Collateral if it takes
such action for that purpose as the applicable Pledgor shall request in writing,
but failure of the U.S. Collateral Agent to comply with any such request shall
not of itself be deemed a failure to exercise reasonable care, and no failure of
the U.S. Collateral Agent to preserve or protect any rights with respect to the
Collateral against prior parties, or to do any act with respect to preservation
of the Collateral not so requested by the such Pledgor, shall be deemed a
failure to exercise reasonable care in the custody or preservation of any
Collateral.

     No delay on the part of the U.S. Collateral Agent in exercising any right,
power or remedy shall operate as a waiver thereof, and no single or partial
exercise of any such right, power or remedy shall preclude any other or further
exercise thereof, or the exercise of any other right, power or remedy. No
amendment, modification or waiver of, or consent with respect to, any provision
of this Agreement shall be effective unless the same shall be in writing and
signed and delivered by the U.S. Collateral Agent, and then such amendment,
modification, waiver or consent shall be effective only in the specific instance
and for the specific purpose for which given.

     All obligations of the Pledgors and all rights, powers and remedies of the
U.S. Collateral Agent and the other Secured Parties expressed herein are in
addition to all other rights, powers and remedies possessed by them, including,
without limitation, those provided by applicable law or in any other written
instrument or agreement relating to any of the Liabilities or any security
therefor.

     This Agreement shall be construed in accordance with and governed by the
laws of the State of New York. Wherever possible each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be prohibited by or
invalid under such law, such provision shall be ineffective to the extent of
such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Agreement.

     This Agreement shall be binding upon the Pledgors and the U.S. Collateral
Agent and their respective successors and assigns, and shall inure to the
benefit of the Pledgors and the U.S. Collateral Agent and the successors and
assigns of the U.S. Collateral Agent.

     This Agreement may be executed in any number of counterparts and by the
different parties hereto on separate counterparts, and each such counterpart
shall be deemed an original but all such counterparts shall together constitute
but one and the same Agreement.

     This Agreement amends and restates in its entirety the Existing Pledge
Agreements which, after the effectiveness hereof, shall no longer be effective
(except for any provisions thereof which by their terms survive, or may be
reinstated, after terminations thereof).

THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, SHALL BE BROUGHT AND MAINTAINED

FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE. EACH PLEDGOR FURTHER

PREPAID, TO THE ADDRESS OF SUCH PLEDGOR SPECIFIED IN, OR PURSUANT TO, THE LOAN
DOCUMENTS, AS APPLICABLE, OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF

EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO
ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT
FORUM. TO THE EXTENT THAT A PLEDGOR HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY
FROM JURISDICTION OF ANY COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH
SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION
OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, SUCH PLEDGOR HEREBY
IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS

collect, as and when due, all amounts due under any of the Non-Tangible
Collateral, including the taking of such action with respect to such collection
as the U.S. Collateral Agent may reasonably request or, in the absence of such
request, as such Debtor may deem advisable, and (c) may grant, in the ordinary
course of business, to any party obligated on any of the Non-Tangible
Collateral, any rebate, refund or allowance to which such party may be lawfully
entitled, and may accept, in connection therewith, the return of Goods, the sale
or lease of which shall have given rise to such Non-Tangible Collateral. The
U.S. Collateral Agent, however, may, at any time that a Default exists, whether
before or after any revocation of such power and authority or the maturity of
any of the Liabilities, notify any parties obligated on any of the Non-Tangible
Collateral to make payment to the U.S. Collateral Agent of any amounts due or to
become due thereunder and enforce collection of any of the Non-Tangible
Collateral by suit or otherwise and surrender, release or exchange all or any
part thereof, or compromise or extend or renew for any period (whether or not
longer than the original period) any indebtedness thereunder or evidenced
thereby. Upon request of the U.S. Collateral Agent during the existence of a
Default, each Debtor

                                       7
<PAGE>

will, at its own expense, notify any parties obligated on any of the
Non-Tangible Collateral to make payment to the U.S. Collateral Agent of any
amounts due or to become due thereunder.

     Upon request by the U.S. Collateral Agent during the existence of a
Default, each Debtor will forthwith, upon receipt, transmit and deliver to the
U.S. Collateral Agent, in the form received, all cash, checks, drafts and other
instruments or writings for the payment of money (properly endorsed, where
required, so that such items may be collected by the U.S. Collateral Agent)
which may be received by such Debtor at any time in full or partial payment or
otherwise as proceeds of any of the Collateral. Except as the U.S. Collateral
Agent may otherwise consent in writing, any such items which may be so received
by any Debtor during the existence of a Default will not be commingled with any
other of its funds or property, but will be held separate and apart from its own
funds or property and upon express trust for the U.S. Collateral Agent for the
benefit of the Secured Parties until delivery is made to the U.S. Collateral
Agent. Each Debtor will comply with the terms and conditions of any consent
given by the U.S. Collateral Agent pursuant to the foregoing sentence.

     During the existence of a Default, all items or amounts which are delivered
by any Debtor to the U.S. Collateral Agent on account of partial or full payment
or otherwise as proceeds of any of the Collateral shall be deposited to the
credit of a deposit account of such Debtor under which the U.S. Collateral Agent
is the depositary bank (each an "Assignee Deposit Account"), as security for
payment of the Liabilities. No Debtor shall have any right to withdraw any funds
deposited in the applicable Assignee Deposit Account. The U.S. Collateral Agent
may, from time to time, in its discretion, and shall upon request of the
applicable Debtor made not more than once in any week, apply all or any of the
then balance, representing collected funds, in the Assignee Deposit Account,
toward payment of the Liabilities, whether or not then due, in such order of
application as the U.S. Collateral Agent may determine, and the U.S. Collateral
Agent may, from time to time, in its discretion, release all or any of such
balance to the applicable Debtor.

     If and to the extent that a perfected security interest hereunder in any
Collateral shall cease to be perfected for any reason whatsoever (including,
without limitation, release of all or any balance in any Assignee Deposit
Account or use or disposition by any Debtor of any proceeds of Collateral), then
such Collateral (referred to in this paragraph as "released Collateral") shall
be deemed thereby released from the security interest hereunder in exchange, as
of the time of such release, for any other Collateral of equivalent value in
which a perfected security interest hereunder is being obtained
contemporaneously

                                       8
<PAGE>

or has been most recently obtained, but only to the extent such other Collateral
does not represent either (a) Collateral in exchange for which any previously
released Collateral shall have been deemed released, or (b) Collateral of
equivalent value to any loan or advance (otherwise than by renewal or extension)
from the U.S. Collateral Agent to the Borrower in which Collateral a perfected
security interest hereunder shall have been obtained contemporaneously with or
most recently prior to such loan or advance.

     During the existence of a Default, the U.S. Collateral Agent is authorized
to endorse, in the name of the applicable Debtor, any item, howsoever received
by the U.S. Collateral Agent, representing any payment on or other proceeds of
any of the Collateral.

5.           Certificates, Schedules and Reports. Each Debtor will from time to
             -----------------------------------
time deliver to the U.S. Collateral Agent such schedules, certificates and
reports respecting all or any of the Collateral at the time subject to the
security interest hereunder, and the items or amounts received by such Debtor in
full or partial payment of any of the Collateral, as the U.S. Collateral Agent
may reasonably request. Any such schedule, certificate or report shall be
executed by a duly authorized officer of such Debtor and shall be in such form
and detail as the U.S. Collateral Agent may specify. Each Debtor shall
immediately notify the U.S. Collateral Agent of the occurrence of any event
causing any loss of its Inventory or other Goods which is material to Holdings
and its Subsidiaries taken as a whole, and such notice shall specify the amount
of such loss.

6.           Agreements of the Debtors. Each Debtor (a) will, upon request of
             -------------------------
the U.S. Collateral Agent, execute such financing statements and other documents
(and pay the cost of filing or recording the same in all public offices
reasonably deemed appropriate by the U.S. Collateral Agent) and do such other
acts and things (including, without limitation, delivery to the U.S. Collateral
Agent of any Instruments or Certificated Securities which constitute
Collateral), all as the U.S. Collateral Agent may from time to time reasonably
request, to establish and maintain a valid security interest in the Collateral
(free of all other liens, claims and rights of third parties whatsoever, other
than Permitted Liens) to secure the payment of the Liabilities; (b) hereby
authorizes the U.S. Collateral Agent to file such financing statements and other
documents without its signature (to the extent allowed by applicable law); (c)
will keep all its Inventory (other than Inventory which is leased to customers
or in transit to or from customer locations), Equipment and other Goods at, and
will not maintain any place of business at any location other than, its
address(es) shown on Schedules I and II hereto or at such other addresses of
                     -----------     --
which such Debtor shall have

                                       9
<PAGE>

given the U.S. Collateral Agent not less than 10 days' prior written notice; (d)
shall not change its state of organization or incorporation or its name,
identity or corporate structure such that any financing statement filed to
perfect the U.S. Collateral Agent's interests under this Agreement would become
seriously misleading, unless the Debtor shall have given the U.S. Collateral
Agent not less than 10 days' prior notice of such change (provided that this
Section 6(d) shall not be deemed to authorize any change or transaction
prohibited under the Credit Agreement); (e) will keep its records concerning the
Non-Tangible Collateral in such a manner as will enable the U.S. Collateral
Agent or its designees to determine at any time the status of the Non-Tangible
Collateral; (f) will furnish the U.S. Collateral Agent such information
concerning such Debtor, the Collateral and the Account Debtors as the U.S.
Collateral Agent may from time to time reasonably request; (g) will permit the
U.S. Collateral Agent and its designees, from time to time, on reasonable notice
and at reasonable times and intervals during normal business hours (or at any
time without notice during the existence of a Default) to inspect such Debtor's
Inventory and other Goods, and to inspect, audit and make copies of and extracts
from all records and all other papers in the possession of such Debtor
pertaining to the Collateral and the Account Debtors, and will, upon request of
the U.S. Collateral Agent during the existence of a Default, deliver to the U.S.
Collateral Agent all of such records and papers; (h) will, upon request of the
U.S. Collateral Agent, stamp on its records concerning the Collateral and add on
all Chattel Paper constituting a portion of the Collateral, a notation, in form
satisfactory to the U.S. Collateral Agent, of the security interest of the U.S.
Collateral Agent hereunder; (i) except for the sale or lease of Inventory in the
ordinary course of its business and sales of Equipment which is no longer useful
in its business or which is being replaced by similar Equipment or as otherwise
permitted by the Credit Agreement, will not create or permit to exist any lien
on or security interest in any Collateral other than Permitted Liens and liens
and security interests in favor of the U.S. Collateral Agent for the benefit of
the Secured Parties; (j) will at all times keep all its Inventory and other
Goods insured under policies maintained with reputable, financially sound
insurance companies against loss, damage, theft and other risks to such extent
as is customarily maintained by companies similarly situated, and cause all such
policies to provide that loss thereunder shall be payable to the U.S. Collateral
Agent as its interest may appear (it being understood that (A) so long as no
Default shall be existing, the U.S. Collateral Agent shall deliver any proceeds
of such insurance which may be received by it to such Debtor and (B) whenever a
Default shall be existing, the U.S. Collateral Agent may apply any proceeds of
such insurance which may be received by it toward the ratable payment of the
Liabilities, whether or not due), and such policies or certificates thereof
shall, if the
<PAGE>

U.S. Collateral Agent so requests, be deposited with or furnished to the U.S.
Collateral Agent; (k) will, upon request of the U.S. Collateral Agent, (i) cause
to be noted on the applicable certificate, in the event any of its Equipment is
covered by a certificate of title, the security interest of the U.S. Collateral
Agent in the Equipment covered thereby and (ii) deliver all such certificates to
the U.S. Collateral Agent or its designees; (l) will take all steps reasonably
necessary to protect, preserve and maintain all of its rights in the Collateral;
(m) will keep all of the tangible Collateral and Deposit Accounts in the
continental United States or, in the case of any Debtor, any province in Canada
of which such Debtor has given the U.S. Collateral Agent not less than 10 days
prior written notice; and (n) will reimburse the U.S. Collateral Agent for all
expenses, including reasonable attorneys' fees and legal expenses, incurred by
the U.S. Collateral Agent in seeking to collect or enforce any rights in respect
of such Debtor's Collateral.

     Any expenses incurred in protecting, preserving and maintaining any
Collateral shall be borne by the applicable Debtor. Whenever a Default shall be
existing, the U.S. Collateral Agent shall have the right to bring suit to
enforce any or all of the Intellectual Property or licenses thereunder, in which
event the applicable Debtor shall at the request of the U.S. Collateral Agent do
any and all lawful acts and execute any and all proper documents required by the
U.S. Collateral Agent in aid of such enforcement and such Debtor shall promptly,
upon demand, reimburse and indemnify the U.S. Collateral Agent for all
reasonable costs and expenses incurred by the U.S. Collateral Agent in the
exercise of its rights under this Section 6, except to the extent any of the
                                  ---------
foregoing result from the gross negligence or willful misconduct of the U.S.
Collateral Agent. Notwithstanding the foregoing, the U.S. Collateral Agent shall
have no obligations or liabilities regarding the Collateral or any thereof by
reason of, or arising out of, this Agreement.

7.           Default.  Whenever a Default shall be existing, the U.S. Collateral
             -------
Agent may exercise from time to time any and all rights and remedies available
to it under the UCC or any other applicable law, in addition to those described
in this section below.

      (a)    Each Debtor agrees, in case of Default, (i) to assemble, at its
expense, all its Inventory and other Goods (other than Fixtures) at a convenient
place or places acceptable to the U.S. Collateral Agent, and (ii) at the U.S.
Collateral Agent's request, to execute all such documents and do all such other
things which may be necessary or desirable in order to enable the U.S.
Collateral Agent or its nominee to be registered

                                      11
<PAGE>

as owner of the Intellectual Property with any competent registration authority.

     (b)   Notice of the intended disposition of any of the Collateral may be
given by first-class mail, hand-delivery (through a delivery service or
otherwise), facsimile or E-mail, and shall be deemed to have been "sent" upon
deposit in the U.S. Mails with adequate postage properly affixed, upon delivery
to an express delivery service or upon the electronic submission through
telephonic or Internet services, as applicable. Each Debtor hereby agrees and
acknowledges that (i) with respect to Collateral that is: (A) perishable or
threatens to decline speedily in value or (B) is of a type customarily sold on a
recognized market (including but not limited to, Investment Property), no notice
of disposition need be given; and (ii) with respect to Collateral not described
in clause (i) of this Section 7(b), notification sent after default and ten days
before any proposed disposition provides notice within a reasonable time before
disposition.

     (c)   Each Debtor hereby agrees and acknowledges that a commercially
reasonable disposition of Inventory, Equipment, Computer Hardware and Software
or Intellectual Property may be by lease or license of, in addition to the sale
of, such Collateral. Each Debtor further agrees and acknowledges that a
disposition (i) made in the usual manner on any recognized market, (ii) a
disposition at the price current in any recognized market at the time of
disposition or (iii) a disposition in conformity with reasonable commercial
practices among dealers in the type of property subject to the disposition
shall, in each case, be deemed commercially reasonable.

     (d)   Any cash proceeds of any disposition by the U.S. Collateral Agent of
any of the Collateral shall be applied by the U.S. Collateral Agent to payment
of expenses in connection with the Collateral, including reasonable attorneys'
fees and legal expenses, and thereafter to the ratable payment of the
Liabilities, and thereafter any surplus will be paid to the applicable Debtor.
The U.S. Collateral Agent need not apply or pay over for application noncash
proceeds of collection and enforcement unless (i) the failure to do so would be
commercially unreasonable and (ii) the affected Debtor has provided the U.S.
Collateral Agent with a written demand to apply or pay over such noncash
proceeds on such basis.

8.         General.  The U.S. Collateral Agent shall be deemed to have exercised
           -------
reasonable care in the custody and preservation of any of the Collateral in its
possession if it takes such action

                                      12
<PAGE>

for that purpose as any applicable Debtor requests in writing, but failure of
the U.S. Collateral Agent to comply with any such request shall not of itself be
deemed a failure to exercise reasonable care, and no failure of the U.S.
Collateral Agent to preserve or protect any rights with respect to such
Collateral against prior parties, or to do any act with respect to the
preservation of such Collateral not so requested by any Debtor, shall be deemed
a failure to exercise reasonable care in the custody or preservation of such
Collateral.

     All notices and requests hereunder shall be in writing (including facsimile
transmission) and shall be sent to the applicable party at its address shown on
Schedule I hereto or at such other address as such party may, by written notice
----------
received by the U.S. Collateral Agent, have designated as its address for such
purpose. Notices sent by facsimile transmission shall be deemed to have been
given when sent; notices sent by mail shall be deemed to have been given three
Business Days after the date when sent by registered or certified mail, postage
prepaid; and notices sent by hand delivery or overnight courier shall be deemed
to have been given when received.

     Each of the Debtors agrees to pay all expenses (including reasonable
attorney's fees and legal expenses) paid or incurred by the U.S. Collateral
Agent or any other Secured Party in endeavoring to collect the Liabilities of
such Debtor, or any part thereof, and in enforcing this Agreement against such
Debtor, and such obligations will themselves be Liabilities.

     No delay on the part of the U.S. Collateral Agent in the exercise of any
right or remedy shall operate as a waiver thereof, and no single or partial
exercise by the U.S. Collateral Agent of any right or remedy shall preclude any
other or further exercise thereof or the exercise of any other right or remedy.

     This Security Agreement shall remain in full force and effect until all
Liabilities have been paid in full and all Commitments have terminated. If at
any time all or any part of any payment theretofore applied by the U.S.
Collateral Agent or any other Secured Party to any of the Liabilities is or must
be rescinded or returned by the U.S. Collateral Agent or such other Secured
Party for any reason whatsoever (including, without limitation, the insolvency,
bankruptcy or reorganization of any Debtor), such Liabilities shall, for the
purposes of this Agreement, to the extent that such payment is or must be
rescinded or returned, be deemed to have continued in existence, notwithstanding
such application by the U.S. Collateral Agent or such other Secured Party, and
this Agreement shall continue to be effective or be reinstated, as the case may
be, as to such Liabilities, all as though such application by the U.S.
Collateral Agent or such other Secured Party had not been made.

                                      13
<PAGE>

     This Agreement shall be construed in accordance with and governed by the
laws of the State of New York(except to the extent that perfection, the effect
of perfection or nonperfection, or the priority of the security interest granted
hereunder may be determined in accordance with the Uniform Commercial Code of a
different jurisdiction in accordance with New York law). Whenever possible, each
provision of this Agreement shall be interpreted in such manner as to be
effective and valid under applicable law, but if any provision of this Agreement
shall be prohibited by or invalid under applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this
Agreement.

     The rights and privileges of the U.S. Collateral Agent hereunder shall
inure to the benefit of its successors and assigns.

     This Agreement may be executed in any number of counterparts and by the
different parties hereto on separate counterparts, and each such counterpart
shall be deemed to be an original, but all such counterparts shall together
constitute one and the same Agreement. At any time after the date of this
Agreement, one or more additional persons or entities may become parties hereto
by executing and delivering to the U.S. Collateral Agent a counterpart of this
Agreement (including supplements to the Schedules hereto). Immediately upon such
execution and delivery (and without any further action), each such additional
person or entity will become a party to, and will be bound by all the terms of,
this Agreement.

     This Agreement amends and restates in its entirety the Existing Security
Agreement which, after the effectiveness hereof, shall no longer be effective
(except for any provisions thereof which by their terms survive, or may be
reinstated, after terminations thereof).

     ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER OR IN CONNECTION WITH
THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, SHALL BE BROUGHT AND MAINTAINED
EXCLUSIVELY IN THE COURTS OF THE STATE OF NEW YORK OR IN THE UNITED STATES
DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK; PROVIDED, HOWEVER, THAT
                                                      --------  -------
ANY SUIT SEEKING ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE
BROUGHT, AT THE U.S. COLLATERAL AGENT'S OPTION, IN THE COURTS OF ANY
JURISDICTION WHERE SUCH COLLATERAL OR OTHER PROPERTY MAY BE FOUND. EACH DEBTOR
HEREBY EXPRESSLY AND IRREVOCABLY SUBMITS TO THE JURISDICTION OF THE COURTS OF
THE STATE OF NEW YORK AND OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN
DISTRICT OF NEW YORK FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE.
EACH DEBTOR FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED
MAIL, POSTAGE PREPAID, TO THE ADDRESS SET

                                      14

FORTH ON SCHEDULE I HERETO (OR SUCH OTHER ADDRESS AS IT SHALL HAVE SPECIFIED IN
         ----------
WRITING TO THE U.S. COLLATERAL AGENT AS ITS ADDRESS FOR NOTICES HEREUNDER) OR BY
PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF NEW YORK. EACH DEBTOR HEREBY
EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY
OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUCH
LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY
SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. TO THE EXTENT THAT
ANY DEBTOR HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY
COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT
PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO
ITSELF OR ITS PROPERTY, SUCH DEBTOR HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY IN
RESPECT OF ITS OBLIGATIONS UNDER THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

     EACH OF EACH DEBTOR, THE U.S. COLLATERAL AGENT AND (BY ACCEPTING THE
BENEFITS HEREOF) EACH OTHER SECURED PARTY HEREBY WAIVES ANY RIGHT TO A TRIAL BY
JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS UNDER THIS
AGREEMENT OR ANY OTHER LOAN DOCUMENT AND ANY AMENDMENT, INSTRUMENT, DOCUMENT OR
AGREEMENT DELIVERED OR WHICH MAY IN THE FUTURE BE DELIVERED IN CONNECTION
HEREWITH OR THEREWITH OR ARISING FROM ANY FINANCING RELATIONSHIP EXISTING IN
CONNECTION WITH ANY OF THE FOREGOING, AND AGREES THAT ANY SUCH ACTION OR
PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY.

                                      15

     IN WITNESS WHEREOF, this Agreement has been duly executed as of the day and

                           FORM OF CANADIAN GUARANTEE

     Guarantee dated as of [X], made by [Name of Guarantor] (the

credit agreement dated as of April ____, 2001, among United Rentals (North
America), Inc., United Rentals, Inc., the Borrower, The Chase Manhattan Bank as
U.S. administrative agent and the Lenders (as amended, modified, extended,
renewed, replaced, restated, supplemented or refinanced from time to time and
including any agreement extending the maturity of, or refinancing or
restructuring (including the inclusion of additional borrowers thereunder or any
increase in the amount borrowed) all or any portion of, the indebtedness under
such agreement or any successor agreements, whether or not with the same agents,
co-agents or lenders, the "Credit Agreement");

B. One of the conditions of the Lenders agreeing to make credit facilities
available to United Rentals (North America), Inc. and the Borrower under the
Credit Agreement was that the Guarantor execute and deliver this guarantee, to
and in favour of Bank of America Canada, as Canadian collateral agent (in such
capacity, the "Canadian Collateral Agent") and the C $ Revolving Lenders (as
defined in the Credit Agreement) (collectively, the "Canadian Secured Parties"),
guaranteeing the payment and performance of all present and future debts,
liabilities and obligations, direct or indirect, absolute or contingent, of the
Borrower to the Canadian Collateral Agent and the other Canadian Secured Parties
arising under, in connection with or pursuant to the Credit Agreement and the
other Loan Documents (as defined in the Credit Agreement); and

C. The Guarantor is a subsidiary (as construed in accordance with the Business
Corporations Act ([Name of Jurisdiction])) of the Borrower and the Guarantor has
determined that it is in the best interests of the Guarantor to enter into this
guarantee;

     NOW THEREFORE in consideration of the foregoing, the sum of $10.00 now paid
by the Canadian Collateral Agent and the other Canadian Secured Parties to

the Guarantor and such other good and valuable consideration, the receipt and
sufficiency of which are acknowledged, the Guarantor agrees as follows:

                                   ARTICLE 1
                                   GUARANTEE

Section 1.1 Guarantee.

     The Guarantor absolutely, irrevocably and unconditionally guarantees the
due and punctual payment to the Canadian Secured Parties, whether at stated
maturity, by acceleration or otherwise, of all present and future debts,

in respect of, the Credit Agreement and the other Loan Documents (as defined in
the Credit Agreement) or any other document executed and delivered by the
Borrower in connection with the Credit Agreement and all Hedging Obligations (as
defined in the Credit Agreement) of the Borrower to the Canadian Secured Parties
(all such obligations, the "Guaranteed Obligations") and promises to pay, on
demand, any and all out-of-pocket expenses (including reasonable counsel fees
and disbursements) incurred by or on behalf of the Canadian Secured Parties in
enforcing any of their respective rights under this guarantee.

Section 1.2 Absolute Liability.

     The Guarantor guarantees that the Guaranteed Obligations will be paid to
the Canadian Collateral Agent and the other Canadian Secured Parties strictly in
accordance with their terms and conditions, that the Guarantor shall be liable
as principal debtor and not solely as surety with respect to the payment of the
Guaranteed Obligations and that the liability of the Guarantor under this
guarantee shall be absolute, irrevocable and unconditional irrespective of:

     (a)  the lack of validity or enforceability of any terms of any of the Loan
          Documents;

     (b)  any contest by the Borrower, United Rentals (North America), Inc. or
          any other Person as to the amount of the Guaranteed Obligations, the
          validity or enforceability of any terms of the Loan Documents or the
          priority of any security granted to the Canadian Collateral Agent or
          the other Canadian Secured Parties;

     (c)  any defence, counter-claim or right of set-off available to the
          Borrower;

     (d)  any extension of the time or times for payment of the Guaranteed
          Obligations or any other indulgences which the Canadian Secured
          Parties may grant to the Borrower, United Rentals (North America),
<PAGE>

                                      - 3 -

          Inc. or any other Person or any amendment to, or alteration or renewal
          of, any of the Loan Documents or the Guaranteed Obligations;

     (e)  any dealings with the security which the Canadian Secured Parties hold
          or may hold pursuant to the terms and conditions of the Loan
          Documents, including the taking, giving up or exchange of securities,
          their variation or realization, the accepting of compositions and the
          granting of releases and discharges, and any release of any other
          guarantor of the Guaranteed Obligations;

     (f)  the assignment of all or any part of the benefits of this guarantee;

     (g)  any invalidity, non-perfection or unenforceability of any security
          held by the Canadian Secured Parties or any irregularity or defect in
          the manner or procedure by which the Canadian Collateral Agent and the
          other Canadian Secured Parties realize on such security; and

     (h)  any other circumstances which might otherwise constitute a defence
          available to, or a discharge of, the Guarantor, the Borrower, United
          Rentals (North America), Inc. or any other Person in respect of the
          Guaranteed Obligations or this guarantee.

                                    ARTICLE 2
                                  ENFORCEMENT

Section 2.1 Remedies.

     The Canadian Secured Parties shall not be bound to exhaust their recourse
against the Borrower, United Rentals (North America), Inc. or any other Person
or realize on any security they may hold in respect of the Guaranteed
Obligations before being entitled to payment under this guarantee and the
Guarantor renounces all benefits of discussion and division.

Section 2.2 Impairment of Security.

     Any loss of, or loss of value of, any security granted to any of the
Canadian Secured Parties by the Borrower, United Rentals (North America), Inc.
or any other Person shall not discharge pro tanto or limit or lessen the
liability of the Guarantor under this guarantee.

Section 2.3 Amount of Guaranteed Obligations.

     Any account settled or stated by or between the Canadian Collateral Agent
and the Borrower, or if any such account has not been settled or stated
immediately before demand for payment under this guarantee, any account stated
by the Canadian Collateral Agent shall, in the absence of manifest mathematical
error, be
<PAGE>

                                      - 4 -

accepted by the Guarantor as conclusive evidence of the amount of the Guaranteed
Obligations which is due by the Borrower to the Canadian Secured Parties or
remains unpaid by the Borrower to the Canadian Secured Parties.

Section 2.4 Payment on Demand.

     The obligation of the Guarantor to pay the amount of the Guaranteed
Obligations and all other amounts payable by it to the Canadian Secured Parties
under this guarantee shall arise, and the Guarantor shall make such payments,
immediately after demand for same is made in writing to it. The liability of the
Guarantor shall bear interest from the date of such demand at the rate or rates
of interest then applicable to the Guaranteed Obligations under and calculated
in the manner provided in the Loan Documents (including any adjustment to give
effect to the provisions of the Interest Act (Canada)).

Section 2.5 Assignment and Postponement.

(1)  All obligations, liabilities and indebtedness of the Borrower, United
     Rentals, Inc. and each of their respective Subsidiaries to the Guarantor of
     any nature whatsoever and all security therefor (the "Intercorporate
     Indebtedness") are assigned and transferred to the Canadian Collateral
     Agent for the benefit of the Canadian Collateral Agent and the other
     Canadian Secured Parties as continuing and collateral security for the
     Guarantor's obligations under this guarantee. Subject to Section 2.5(2) and
     Section 2.5(3), until notice by the Canadian Collateral Agent to the
     Guarantor that the Guaranteed Obligations have become due and payable, the
     Guarantor may receive payments in respect of the Intercorporate
     Indebtedness in accordance with their terms. The Guarantor shall not,
     except with the written consent of the Canadian Collateral Agent and the
     other Canadian Secured Parties, assign all or any part of the
     Intercorporate Indebtedness to any Person other than the Canadian
     Collateral Agent or the other Canadian Secured Parties.

(2)  Upon the occurrence and during the continuance of an Event of Default under
     and as defined in the Credit Agreement, all Intercorporate Indebtedness
     shall be held in trust for the Canadian Secured Parties and shall be
     collected, enforced or proved subject to, and for the purpose of, this
     guarantee and any payments received by the Guarantor in respect of the
     Intercorporate Indebtedness shall be segregated from other funds and
     property held by the Guarantor and immediately paid to the Canadian
     Collateral Agent on account of the Guaranteed Obligations.

(3)  Upon the occurrence and during the continuance of an Event of Default under
     and as defined in the Credit Agreement, the Canadian Secured Parties shall
     be entitled to receive payment of the Guaranteed Obligations in full before
     the Guarantor receives any payment on account of the Intercorporate
<PAGE>

                                      - 5 -

     Indebtedness. In such case, the Intercorporate Indebtedness shall not be
     released or withdrawn by the Guarantor unless the Canadian Collateral
     Agent's written consent to the release or withdrawal is first obtained. The
     Guarantor shall not permit the prescription of the Intercorporate
     Indebtedness by any statute of limitations or ask for or obtain any
     security or negotiable paper for, or other evidence of, the Intercorporate
     Indebtedness except for the purpose of delivering the same to the Canadian
     Collateral Agent.

Section 2.6 Suspension of Guarantor Rights.

     The Guarantor irrevocably waives any rights which it may at any time have
by reason of the performance of any of its obligations under this guarantee (i)
to be indemnified by the Borrower, (ii) to claim contribution from any other
guarantor of the debts, liabilities or obligations of the Borrower, or (iii)
subject to Section 2.8, to take the benefit (in whole or in part and whether by
way of subrogation or otherwise) of any rights of the Canadian Secured Parties
under any of the Loan Documents.

Section 2.7 No Prejudice to Canadian Secured Parties or Canadian Collateral
            Agent.

     The Canadian Secured Parties shall not be prejudiced in any way in the
right to enforce any provision of this guarantee by any act or failure to act on
the part of the Borrower, United Rentals (North America), Inc., United Rentals,
Inc., the Canadian Collateral Agent or the other Canadian Secured Parties. The
Canadian Collateral Agent and the other Canadian Secured Parties may, at any
time and from time to time, in such manner as any of them may determine is
expedient, without any consent of, or notice to, the Guarantor and without
impairing or releasing the obligations of the Guarantor (i) change the manner,
place, time or terms of payment of, or renew or alter, the Guaranteed
Obligations, (ii) renew, increase or otherwise vary any credit or credit
facilities to, or the terms or conditions of any transaction with, the Borrower,
United Rentals (North America), Inc. or any other Person, (iii) release,
compound or vary the liability of the Borrower, United Rentals (North America),
Inc. or any other Person liable in any manner under or in respect of the
Guaranteed Obligations, (iv) exercise or enforce or refrain from exercising or
enforcing any right or security against the Borrower, United Rentals (North
America), Inc., the Guarantor or any other Person, and (v) apply any sums from
time to time received to the Guaranteed Obligations. In their dealings with the
Borrower and United Rentals (North America), Inc., the Canadian Collateral Agent
and the other Canadian Secured Parties need not enquire into the authority or
power of any Person purporting to act for or on behalf of the Borrower or United
Rentals (North America), Inc.

Section 2.8 No Subrogation.

     The Guarantor irrevocably waives any claim, remedy or other right which it
may now have or hereafter acquire against the Borrower that arises from the
existence, payment, performance or enforcement of the Guarantor's obligations
under this guarantee, including any right of subrogation, reimbursement,
exoneration or indemnification or any right to participate in any claim or
remedy of the Canadian Secured Parties against the Borrower or any collateral
which the Canadian Secured Parties now have or hereafter acquire, whether or not
such claim, remedy or other right is reduced to judgment or is liquidated,
unliquidated, fixed, contingent, matured, unmatured, disputed, undisputed,
secured or unsecured, and whether or not such claim, remedy or other right
arises in equity or under contract, statute or common law. The Guarantor further
agrees that the Borrower shall be an intended third party beneficiary of the
Guarantor's waiver contained in this Section 2.8. If any amount is paid to the
Guarantor in violation of this section and, at such time, the Canadian Secured
Parties' claims against the Borrower in respect of the Guaranteed Obligations
shall not have been paid in full, any amount paid to the Guarantor shall be
deemed to have been paid to the Guarantor for the benefit of, and held in trust
for, the Canadian Secured Parties, and shall immediately be paid to the Canadian
Collateral Agent to be credited and applied upon such Guaranteed Obligations.
The Guarantor acknowledges that it will receive direct and indirect benefits
from the transactions contemplated by this guarantee and that the waiver in this
Section 2.8 is knowingly made in contemplation of such benefits.

Section 2.9 No Set-off.

     To the fullest extent permitted by law, the Guarantor shall make all
payments under this guarantee without regard to any defence, counter-claim or
right of set-off available to it.

Section 2.10 Successors of the Borrower.

     Any change or changes in the name of, or reorganization (whether by way of
reconstruction, consolidation, amalgamation, merger, transfer, sale, lease or
otherwise) of, the Borrower or its business shall not affect or in any way limit
or lessen the liability of the Guarantor under this guarantee or under any of
the Guarantor Security Agreements (as defined below). This guarantee and the
Guarantor Security Agreements shall extend to any person, firm or corporation
acquiring or from time to time carrying on the business of the Borrower.

Section 2.11 Continuing Guarantee.

     This guarantee is a continuing guarantee. It extends to all present and
future Guaranteed Obligations, applies to and secures the ultimate balance of
the Guaranteed Obligations due or remaining due to the Canadian Collateral Agent
and the other Canadian Secured Parties and shall be binding as a continuing
obligation
<PAGE>

                                      - 7 -

of the Guarantor until the Canadian Collateral Agent and the other Canadian
Secured Parties release the Guarantor. This guarantee shall continue to be
effective or be reinstated, as the case may be, if at any time any payment of
any of the Guaranteed Obligations is rescinded or must otherwise be returned by
the Canadian Secured Parties upon the insolvency, bankruptcy or reorganization
of the Borrower or otherwise, all as though the payment had not been made.

Section 2.12 Supplemental Security.

     This guarantee is in addition and without prejudice to and supplemental to
all other guarantees and securities held or which may hereafter be held by the
Canadian Secured Parties.

Section 2.13 Security for Guarantee.

     The Guarantor acknowledges that this guarantee is intended to secure
payment of the Guaranteed Obligations and that the payment of the Guaranteed
Obligations and the other obligations of the Guarantor under this guarantee are
secured pursuant to the terms and provisions of those agreements described in
Schedule "A" (collectively, the "Guarantor Security Agreements").

Section 2.14 Right of Set-off.

     Upon the occurrence and during the continuance of any Event of Default
under and as defined in the Credit Agreement, the Canadian Collateral Agent and
each of the other Canadian Secured Parties are authorized by the Guarantor at
any time and from time to time and may, to the fullest extent permitted by law,
set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other indebtedness at any time owing
by the Canadian Collateral Agent or the other Canadian Secured Parties to or for
the credit or the account of the Guarantor against any and all of the
obligations of the Guarantor now or hereafter existing irrespective of whether
or not (i) the Canadian Secured Parties have made any demand under this
guarantee, or (ii) any of the obligations comprising the Guaranteed Obligations
are contingent or unmatured. The rights of the Canadian Collateral Agent and the
other Canadian Secured Parties under this Section 2.14 are in addition and
without prejudice to and supplemental to other rights and remedies which the
Canadian Collateral Agent and the other Canadian Secured Parties may have.

Section 2.15 Interest Act (Canada).

     The Guarantor acknowledges that certain of the rates of interest applicable
to the Guaranteed Obligations may be computed on the basis of a year of 360 days
or 365 days, as the case may be and paid for the actual number of days elapsed.
For purposes of the Interest Act (Canada), whenever any interest is calculated
using a rate based on a year of 360 days or 365 days, as the case may be, such
rate
<PAGE>

                                     - 8 -

determined pursuant to such calculation, when expressed as an annual rate is
equivalent to (i) the applicable rate based on a year of 360 days or 365 days,
as the case may be, (ii) multiplied by the actual number of days in the calendar
year in which the period for such interest is payable (or compounded) ends, and
(iii) divided by 360 or 365, as the case may be.

Section 2.16 Taxes and Other Taxes.

(1)  All payments to the Canadian Collateral Agent or the other Canadian Secured
     Parties by the Guarantor under this guarantee or under any of the Guarantor
     Security Agreements shall be made free and clear of and without deduction
     or withholding for any present or future income, excise, stamp or franchise
     taxes and other taxes, fees, duties, withholdings or other charges of any
     nature whatsoever imposed by any taxing authority, but excluding franchise
     taxes and taxes imposed on or measured by any Lender's net income or
     receipts (all non-excluded items being called "Taxes"). If any withholding
     or deduction from any payment to be made by the Guarantor hereunder
     (including any additional amount or amounts to be paid under this Section
     2.16) is required in respect of any Taxes pursuant to any applicable law,
     rule or regulation, then the Guarantor will:

     (a)  pay directly to the relevant authority the full amount required to be
          so withheld or deducted;

     (b)  promptly forward to the Canadian Collateral Agent an official receipt
          or other documentation satisfactory to the Canadian Collateral Agent
          evidencing such payment to such authority; and

     (c)  pay to the Canadian Collateral Agent for the account of the Canadian
          Secured Parties such additional amount or amounts as is necessary to
          ensure that the net amount actually received by each Canadian Secured
          Parties will equal the full amount such Canadian Secured Parties would
          have received had no such withholding or deduction been required.

     Moreover, if any Taxes are directly asserted against the Canadian
     Collateral Agent or any other Canadian Secured Party with respect to any
     payment received by the Canadian Collateral Agent or such other Canadian
     Secured Party hereunder, the Canadian Collateral Agent or such other
     Canadian Secured Party may pay such Taxes and the Guarantor will promptly
     pay such additional amounts (including any penalty, interest and expense)
     as is necessary in order that the net amount received by such Person after
     the payment of such Taxes (including any Taxes on such additional amount)
<PAGE>

                                     - 9 -

     shall equal the amount such Person would have received had such Taxes not
     been asserted.

(2)  If the Guarantor fails to pay any Taxes when due to the appropriate taxing
     authority or fails to remit to the Canadian Collateral Agent, for the
     account of the applicable Canadian Secured Parties, the required receipts
     or other required documentary evidence, the Guarantor shall indemnify such
     Canadian Secured Parties for any incremental Taxes, interest or penalties
     that may become payable by any such Canadian Secured Party as a result of
     any such failure. For purposes of this Section 2.16, a distribution
     hereunder by the Canadian Collateral Agent or any Canadian Secured Party to
     or for the account of any Canadian Secured Party shall be deemed a payment
     by the Guarantor.

(3)  The provisions of this Section 2.16 shall survive the termination of this
     guarantee.

Section 2.17 Judgment Currency.

(1)  If for the purposes of obtaining judgment in any court it is necessary to
     convert all or any part of the Guaranteed Obligations or any other amount
     due to a Canadian Secured Party in respect of the Guarantor's obligations
     under this guarantee in any currency (the "Original Currency") into another
     currency (the "Other Currency"), the Guarantor, to the fullest extent that
     it may effectively do so, agrees that the rate of exchange used shall be
     that at which, in accordance with normal banking procedures, such Canadian
     Secured Party, as the case may be, could purchase the Original Currency
     with the Other Currency on the Business Day preceding that on which final
     judgment is paid or satisfied.

(2)  The obligations of the Guarantor in respect of any sum due in the Original
     Currency from it to any Canadian Secured Party shall, notwithstanding any
     judgment in any Other Currency, be discharged only to the extent that on
     the Business Day following receipt by such Canadian Secured Party of any
     sum adjudged to be so due in such Other Currency such Canadian Secured
     Party may, in accordance with its normal banking procedures, purchase the
     Original Currency with such Other Currency. If the amount of the Original
     Currency so purchased is less than the sum originally due to such Canadian
     Secured Party in the Original Currency, the Guarantor agrees, as a separate
     obligation and notwithstanding any such judgment, to indemnify such
     Canadian Secured Party against such loss, and if the amount of the Original
     Currency so purchased exceeds the sum originally due to such Canadian
     Secured Party in the Original Currency, such Canadian Secured Party agrees
     to remit such excess to the Guarantor.

     this security agreement or additional security agreements as may be
     required by the Canadian Collateral Agent.

Section 1.5 Scope of Security Interest.

(1)  To the extent that the creation of the Security Interest would constitute a
     breach or permit the acceleration or termination of any agreement, right,
     licence or permit of the Obligor (each, a "Restricted Asset"), the
     Security Interest created hereunder will constitute a trust created in
     favour of the Canadian Secured Parties pursuant to which the Obligor shall
     hold as trustee its interest in all proceeds arising under or in connection
     with the Restricted Asset in trust for the Canadian Collateral Agent on the
     following basis:

          (i)  until the Security Interest has become enforceable, the Obligor
               shall be entitled to receive all such proceeds; and
<PAGE>

                                     - 5 -

          (ii) whenever the Security Interest has become enforceable, all rights
               of the Obligor to receive such proceeds shall cease, the Obligor
               shall at the request of the Canadian Collateral Agent take all
               such actions to collect and enforce payment and other rights
               arising under the Restricted Asset in accordance with the
               instructions of the Canadian Collateral Agent and all such
               proceeds arising under or in connection with the Restricted Asset
               shall be immediately paid over to the Canadian Collateral Agent
               for the benefit of the Canadian Secured Parties.

     The Obligor shall not exercise any rights of set-off with respect to
     amounts payable under or in connection with any Restricted Asset and shall
     use its best efforts to ensure that no other party to the Restricted Asset
     shall exercise any rights of set-off against any amounts payable
     thereunder. The Obligor shall use its best efforts to obtain the consent of
     each other party to the Restricted Asset to the creation of a security
     interest in the Restricted Asset in favour of the Canadian Collateral Agent
     in accordance with this security agreement and shall use its best efforts
     to ensure that all agreements entered into on and after the date hereof
     expressly permit the creation of a security interest in the Restricted
     Asset in favour of the Canadian Collateral Agent in accordance with the
     terms of this security agreement.

(2)  Until the Security Interest shall have become enforceable, the grant of the
     Security Interest in the Intellectual Property shall not affect in any way
     the Obligor's rights to commercially exploit the Intellectual Property,
     defend it, enforce the Obligor's rights in it or with respect to it against
     third parties in any court or claim and be entitled to receive any damages
     with respect to any infringement of it.

(3)  The Security Interest shall not extend to consumer goods.

(4)  The Security Interest shall not extend or apply to the last day of the term
     of any lease or sublease or any agreement for a lease or sublease, now held
     or hereafter acquired by the Obligor in respect of real property, but the
     Obligor shall stand possessed of any such last day upon trust to assign and
     dispose of it as the Canadian Collateral Agent may direct.

Section 1.6 Grant of Licence to Use Intellectual Property.

     For purposes of enabling the Canadian Collateral Agent to exercise its
rights and remedies pursuant to Article 2, at such time as the Canadian
Collateral Agent shall be lawfully entitled to exercise its rights and remedies
and for no other purpose, the Obligor grants to the Canadian Collateral Agent an
irrevocable, nonexclusive licence (exercisable without payment of royalty or
other compensation to the Obligor) to use, assign or sublicense any of the
Intellectual Property wherever
<PAGE>

                                      - 6 -

the same may be located, including in such licence access to (i) all media in
which any of the licensed items may be recorded or stored, and (ii) all computer
programs used for compilation or print-out.

Section 1.7 Care and Custody of Collateral.

(1)  The Canadian Collateral Agent and the other Canadian Secured Parties shall
     have no obligation to keep Collateral in their possession identifiable.

(2)  The Canadian Collateral Agent may, after the Security Interest shall have
     become enforceable, (i) notify any person obligated on an account or on
     chattel paper or any obligor on an instrument to make payments to the
     Canadian Collateral Agent whether or not the Obligor was previously making
     collections on such accounts, chattel paper or instruments, and (ii) assume
     control of any proceeds arising from the Collateral.

                              ARTICLE 2 ENFORCEMENT

Section 2.1 Enforcement.

     The Security Interest shall be and become enforceable against the Obligor
upon the occurrence and during the continuance of an Event of Default (under and
as defined in the Credit Agreement).

Section 2.2 Remedies.

     Whenever the Security Interest has become enforceable, the Canadian
Collateral Agent may realize upon the Collateral and enforce the rights of the
Canadian Collateral Agent and the other Canadian Secured Parties by:

     (a)  entry onto any premises where Collateral consisting of tangible
          personal property may be located;

     (b)  entry into possession of the Collateral by any method permitted by
          law;

     (c)  sale or lease of all or any part of the Collateral;

     (d)  collection of any proceeds arising in respect of the Collateral;

     (e)  collection, realization or sale of, or other dealing with, the
          accounts;

     (f)  appointment by instrument in writing of a receiver (which term as used
          in this security agreement includes a receiver and manager) or agent
          of all or any part of the Collateral and removal or replacement from
          time to time of any receiver or agent;
<PAGE>

                                     - 7 -

     (e)  Collateral may be disposed of in any manner and on any terms necessary
          to avoid violation of applicable law (including, without limitation,

          bidders and purchasers have certain qualifications, and restrict the
          prospective bidders and purchasers to persons who will represent and
          agree that they are purchasing for their own account for investment
          and not with a view to the distribution or resale of the Collateral)

          the resulting purchase) by any governmental or regulatory authority or
          official;

          inventory and other goods, and to inspect, audit and make copies of
          and extracts from all records and all other papers in the possession
          of the Obligor pertaining to the Collateral and the account debtors of

          policies maintained with reputable, financially sound insurance
          companies against loss, damage, theft and other risks to such extent

          cause all such policies to provide that loss thereunder shall be
          payable to the Canadian Collateral Agent as its interest may appear
          (it being understood that (A) so long as the Security Interest has not
          become enforceable, the Canadian Collateral Agent shall deliver any
          proceeds of such insurance which may be received by it to the Obligor
          and (B) whenever the Security Interest has become enforceable, the
          Canadian Collateral Agent may apply any proceeds of such insurance
          which may be received by it toward payment of the Obligations, whether
          or not due, in such order of application as the Canadian Collateral
          Agent may determine) and such policies or certificates thereof shall,
          if the Canadian Collateral Agent, so requests, be deposited with or
          furnished to the Canadian Collateral Agent;

     (j)  take such actions as are reasonably necessary to keep its inventory in

          assessments and other charges which may be levied upon or assessed
          against the ownership, operation, possession, maintenance or use of

          the Obligor shall not be required to pay any such fee, tax, assessment
          or other charge if the validity thereof is being contested by the
          Obligor in good faith by appropriate proceedings, so long as
          forfeiture of any substantial part of its equipment or other goods
          will not result from the failure of the Obligor to pay any such fee,
          tax, assessment or other charge during the period of such contest;

     (m)  upon request of the Canadian Collateral Agent, (i) cause to be noted
          on the applicable certificate, in the event any of its equipment is
          covered by a certificate of title, the security interest of the

          Agent and the other Canadian Secured Parties in the equipment covered
          thereby and (ii) deliver all such certificates to the Canadian

          aggregate value of not more than $200,000 that is: (i) equipment
          leased in the ordinary course of business to a customer where the
          aggregate value of all equipment leased to such customer does not
          exceed $150,000 or (ii) equipment leased in the ordinary course of
          business to a customer that has been removed by such customer from one
          of the jurisdictions specified in Schedule "B" in breach of the lease

Canadian Collateral Agent and the other Canadian Secured Parties may have,

prejudice to the rights of the Canadian Collateral Agent and the other Canadian

     Borrowers shall resume making payments in respect of the subordinated
     notes, unless clause (a) above is then applicable.

     to stated maturity because of the occurrence of any default thereunder or
     under the agreement or instrument under which they are issued or otherwise
     than at the option of the Borrowers, under circumstances when clause (a)

Indebtedness shall be deemed to be irrevocably appointed the agent and attorney-
in-fact of the holder of such note to execute, verify, deliver and file any such
proof of claim, consent, assignment or other instrument.

3.   No right of any holder of any Superior Indebtedness to enforce
subordination as herein provided shall at any time or in any way be affected or
impaired by any failure to act on the part of the Borrowers or any holder of
Superior Indebtedness, or by any non-compliance by the Borrowers with any term,
provision or covenant of the subordinated notes or the agreement under which
they are issued, regardless of any knowledge thereof that any such holder of
Superior Indebtedness may have or be otherwise charged with.

4.   The Borrowers agree, for the benefit of the holders of Superior
Indebtedness, that in the event that any subordinated note is declared due and
payable before its expressed maturity because of the occurrence of a default

Indebtedness.
